We examined the benefit of tissue plasminogen activator (tPA), delivered as part of usual stroke management, on patient-reported outcomes and health care utilization. Using a case control design, patients who received tPA as part of usual stroke management were compared with patients who would have received tPA had they arrived to the hospital within the therapeutic time window. Data were collected from surveys 6 months after stroke using standardized patient-reported outcome measures and questions about health care utilization. Demographic and medical data were acquired from hospital records. Patients were matched on stroke severity, age, race, and gender. Matching was done with 1:2 ratio of tPA to controls. Results were compared between groups with 1-tailed tests because of a directionally specific hypothesis in favor of the tPA group. The tPA (n = 78) and control (n = 156) groups were matched across variables, except for stroke severity, which was better in the control group; subsequent analyses controlled for this mismatch. The tPA group reported better physical function, communication, cognitive ability, depressive symptomatology, and quality of life/participation compared with the control group. Fewer people in the tPA group reported skilled nursing facility stays, emergency department visits, and rehospitalizations after their stroke compared with controls. Reports of other postacute services were not different between groups. Although it is known that tPA reduces disability, this is the first study to demonstrate the effectiveness of tPA in improving meaningful, patient-reported outcomes. Thus, use of tPA provides a large benefit to the daily lives of people with ischemic stroke. Copyright © 2014 National Stroke Association. Published by Elsevier Inc. All rights reserved.

The aim of this study was to examine over a 12-month post-intervention period whether the participation of community-living individuals with mental illness in cognitive behavioral group therapy for recovery of self-esteem (CBGTRS) resulted in improved outcomes. This was a non-randomized controlled trial. The participants were persons with mental illness who resided in communities in the Chugoku region of Japan. In total, 41 were assigned to an experimental group (CBGTRS intervention, 12 group sessions), and 21 to a control group. Outcome indices (self-esteem, moods, cognition, subjective well-being, psychiatric symptoms) were measured for the experimental group prior to intervention (T0), immediately post-intervention (T1), and at 3 (T2) and 12 (T3) months post-intervention. The control group was measured at the same intervals. For the experimental group, self-esteem scores at T1, T2, and T3 were significantly higher than at T0. Moods and cognition scores remained significantly low until T2. Scores for Inadequate Mental Mastery in the subjective well-being index had not decreased by T3. Confidence in Coping remained significantly high until T2. Psychiatric symptoms scores at T0, T1, T2, and T3 were significantly lower than at T0. The means and standard errors for self-esteem and Inadequate Mental Mastery increased until T3, and those for Tension-Anxiety, Depression-Dejection, and Confusion decreased until T2. From within-group trends and between-group differences in self-esteem, we conclude that CBGTRS may have a relatively long-term effect on self-esteem recovery. T2 is the turning point for moods and cognition; thus, follow-up is needed 3 months following the initial program. © 2016 The Authors.

The aim was to compare periodontal and periimplant inflammatory parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD] and marginal bone loss [MBL]) among patients with prediabetes, type-2 diabetes mellitus (T2DM) and non-diabetic controls. Forty-five patients with prediabetes (Group-1), 43 patients with T2DM (Group-2) and 42 controls (Group-3) were included. Demographic data was recorded using a questionnaire. Full mouth and periimplant clinical (PI, BOP and PD) were assessed and the radiographic MBL were measured on digital radiographs. In all groups, haemoglobin A1c (HbA1c) levels were also measured. p values less than .05 were considered statistically significant. The mean HbA1c levels of participants in groups 1, 2 and 3 were 6.1%, 8.4% and 4.8%, respectively. The mean duration of prediabetes and T2DM among patients in groups 1 and 2 were 1.9 ± 0.3 and 3.1 ± 0.5 years, respectively. Periodontal and periimplant PI, BOP, PD and MBL were higher in groups 1 (p < .05) and 2 (p < .05) than group 3. There was no difference in these parameters in groups 1 and 2. Periodontal and periimplant inflammatory parameters were worse among patients with prediabetes and T2DM compared with controls; however, these parameters were comparable among patients with prediabetes and T2DM.

The purpose of study was to compare the effect of primary motor cortex (M1) and cerebellar anodal transcranial direct current stimulation (a-tDCS) on online and offline motor learning in healthy individuals. Fifty-nine healthy volunteers were randomly divided into three groups (n=20 in two experimental groups and n=19 in sham-control group). One experimental group received M1a-tDCSand another received cerebellar a-tDCS. The main outcome measure were response time (RT) and number of errors during serial response time test (SRTT) which were assessed prior, 35min and 48h after the interventions. Reduction of response time (RT) and error numbers at last block of the test compared to the first block was considered online learning. Comparison of assessments during retention tests was considered as short-term and long-term offline learning. Online RT reduction was not different among groups (P>0.05), while online error reduction was significantly greater in cerebellar a-tDCS than sham-control group (P<0.017). Moreover, a-tDCS on both M1 and cerebellar regions produced more long-term offline learning as compared to sham tDCS (P<0.01), while short-term offline RT reduction was significantly greater in M1a-tDCS than sham-control group (P<0.05). The findings indicated that although cerebellar a-tDCS enhances online learning and M1a-tDCS has more effect on short-term offline learning, both M 1 and cerebellar a-tDCS can be used as a boosting technique for improvement of offline motor learning in healthy individuals.

Chronic fungal infections are known to exacerbate allergic symptoms, including those of asthma and chronic urticaria (CU). We applied four prepared fungal antigens of Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, and Candida albicans to examine sensitization to each in subjects with CU and onychomycosis and in healthy subjects, and to evaluate the etiologic role of dermatophytic infection in CU and observe any cross-reactions among these four antigens. Participants were divided into four groups, including those with CU with onychomycosis (experiment group), those with onychomycosis without allergic diseases (control group 1), those with CU without fungal infections (control group 2), and a healthy group (control group 3). In all subjects, skin prick tests with the four fungal antigens were performed. Subjects in the experiment group and control group 1 were also submitted to mycologic investigations. The experiment group showed significantly higher rates of positivity than the three control groups to T. rubrum, E. floccosum, and T. mentagrophytes antigens. Control group 1 showed rates higher than those in control groups 2 and 3; no significant difference emerged between control groups 2 and 3. Positivity to the C. albicans antigen did not differ among the four groups. In control group 1, rates of positivity to the three dermatophytic antigens did not differ significantly but did for C. albicans. Fungal infection seems to be an important determinant of trichophyton hypersensitivity. Cross-reactions among T. mentagrophytes, T. rubrum, and E. floccosum antigens were obvious, but none emerged between the antigens of the three dermatophytes and that of C. albicans. © 2016 The International Society of Dermatology.

The superiority of an intervention combining two sets of theory-based behavior change techniques targeting planning and self-efficacy over an intervention targeting planning only or self-efficacy only has rarely been investigated. We compared the influence of self-efficacy, planning, and self-efficacy+planning interventions with an education-based control condition on adolescents' body fat, assuming mediating effects of respective social cognitive variables and moderate-to-vigorous physical activity (MVPA). The moderating role of the built environment was examined. Participants (N = 1217, aged 14-18 years) were randomly assigned to four conditions: planning (n = 270), self-efficacy (n = 311), self-efficacy+planning (n = 351), and control (n = 285). The measurement was conducted at baseline (T1), two-month follow-up (T2), and fourteen-month follow-up (T3). Interventions/control group procedures were delivered at T1 and T2. Percent of body fat tissue (measured at T1 and T3) was the main outcome. Social cognitive mediators (self-efficacy and planning) were assessed at T1 and T2. The behavioral mediator (MVPA) and the presence of built MVPA facilities (the moderator) were evaluated at T1 and T3. Similar small increases of body fat were found across the three intervention groups, but the increment of body fat was significantly larger in the control group. On average, differences between control and intervention groups translated to approximately 1% of body fat. Effects of the interventions on body fat were mediated by relevant social cognitive variables and MVPA. A lower increase of body fat was found among intervention group participants who had access to newly-built MVPA facilities. We found no superiority of an intervention targeting two social cognitive variables over the intervention targeting one cognition only.

This study aimed to evaluate the potential of Moringa oleifera fresh leaves (MOL) as feed supplement on the performance and egg quality of Rhode Island Red (RIR) hens under the tropical conditions of Yucatan, Mexico. Forty-eight RIR hens were allocated in 12 floor pen replicates each with four birds. Thereafter, the replicates were divided into three groups which were corresponded to ad libitum feed (control), ad libitum feed supplemented with MOL T1 (AL + MOL) and restricted feed amount (20% lower than control) with MOL T2 (RCD + MOL), respectively. T1 (AL + MOL) had higher egg laying rate (71.4% versus 66.6%), higher daily egg mass production (45.4 versus 41.9 g/day), lower feed intake (121.3 versus 127.5 g/day) and better feed conversion ratio (2.8 versus 3.2 g feed:g egg) versus control. T2 / (RCD + MOL) had lower values of body weight, egg laying rate, egg weight and egg mass, and recorded better feed conversion ratio than the control group. The control group recorded a higher percentage of pecked eggs versus T1 and T2 (6.5% versus 1.2% and 2.0 %). Similar intake of MOL (3.1 and 3.4 g DM/day) was recorded in T1 (AL + MOL) and T2 (RCD + MOL). Yolk color was improved significantly in T1 (AL + MOL) than both control and T2 (RCD + MOL), while T2 (RCD + MOL) had eggs with lower yolk and higher albumen percentages than the other two ad libitum groups. The results suggest that MOL could be used successfully as sustainable tropical feed resource for RIR hens.

To investigate the changes of proliferative activity and reactive oxygen species level of human epidermal cell line HaCaT after being irradiated with low-energy 633 nm red light. Irradiation distance was determined through preliminary experiment. HaCaT cells were conventionally sub-cultured with RPMI 1640 culture medium containing 10% fetal calf serum, 100 U/mL penicillin, and 100 μg/mL streptomycin. Cells of the third passage were used in the following experiments. (1) Cells were divided into blank control group and 0.082, 0.164, 0.245, 0.491, 1.472, 2.453, 4.910, and 9.810 J/cm(2) irradiation groups according to the random number table, with 3 wells in each group. Cells in blank control group were not irradiated, while cells in the latter 8 irradiation groups were irradiated with 633 nm red light for 10, 20, 30, 60, 180, 300, 600, and 1 200 s in turn. Cells were reirradiated once every 8 hours. After being irradiated for 48 hours (6 times) in irradiation groups, the proliferative activity of cells in 9 groups was determined with cell counting kit 8 and microplate reader (denoted as absorbance value). (2) Another batch of cells were grouped and irradiated as in experiment (1). After being irradiated for once in irradiation groups, cells in 9 groups were conventionally cultured for 60 min with detection reagent of reactive oxygen species. At post culture minute (PCM) 0 (immediately), 30, 60, and 120, reactive oxygen species level of cells was determined with microplate reader (denoted as absorbance value). (3) Another batch of cells were divided into blank control group, 0.082, 0.491, 2.453, and 9.810 J/cm(2) irradiation groups, and positive control group. Cells in blank control group and positive control group were not irradiated (positive control reagent of reactive oxygen species was added to cells in positive control group), and cells in irradiation groups were irradiated as in experiment (1) for once. The expression of reactive oxygen species in cells of each group was observed by confocal laser scanning microscope. Data were processed with one-way analysis of variance, analysis of variance for repeated measurement, and t test. (1) Irradiation distance was 10 cm. Proliferative activity of cells in blank control group and 0.082, 0.164, 0.245, 0.491, 1.472, 2.453, 4.910, and 9.810 J/cm(2) irradiation groups was 1.000, 1.116±0.031, 1.146±0.016, 1.162±0.041, 1.179±0.016, 1.207±0.016, 1.247±0.040, 1.097±0.059, and 0.951±0.118, respectively. Compared with that in blank control group, proliferative activity of cells in 0.082-2.453 J/cm(2) irradiation groups was significantly higher (with t values from -22.803 to -6.779, P values below 0.05). Proliferative activity of cells in 4.910 and 9.810 J/cm(2) irradiation groups was similar to that in blank control group (with t values respectively -2.854 and 0.711, P values above 0.05). (2) Compared with that in blank control group, reactive oxygen species level of cells was significantly enhanced at PCM 0 and 30 in 0.164-2.453 J/cm(2) irradiation groups (with t values from -12.453 to -4.684, P<0.05 or P<0.01), while that showed no significant change in 0.082, 4.910, and 9.810 J/cm(2) irradiation groups (with t values from -3.925 to -0.672, P values above 0.05). Compared with that in blank control group, reactive oxygen species level of cells was significantly enhanced at PCM 60 in 0.082-2.453 J/cm(2) irradiation groups (with t values from -11.387 to -4.717, P<0.05 or P<0.01). Compared with that in blank control group, reactive oxygen species level of cells was significantly enhanced at PCM 120 in 0.491-2.453 J/cm(2) irradiation groups (with t values from -10.657 to -6.644, P<0.05 or P<0.01). (3) Compared with that in blank control group, the expression of reactive oxygen species of cells was increased in 0.082, 0.491, and 2.453 J/cm(2) irradiation groups and positive control group. The expression of reactive oxygen species of cells in 9.810 J/cm(2) irradiation group was attenuated when compared with the expressions in the other irradiation groups. Reactive oxygen species expressed in mitochondria of cells in each group. Low-energy 633 nm red light can enhance the proliferation of human epidermal cell line HaCaT, and the effect is closely related to the increase of reactive oxygen species produced by mitochondria after being stimulated by red light irradiation.

Eating disorders associated to type 1 diabetes (T1D) raise the risk of impairments in metabolic control increasing short and long term complications. To compare the glycosylated hemoglobin (HbA1c) levels variation in a group of T1D adolescents with and without disordered eating behaviour (DEB) during 3-year follow-up and to relate the metabolic control, with pubertal stage, T1D duration, Body Mass Index and gender at the end of the study. Analytyc an observational comparative study of two cohorts: patients were selected from a previous multicentric study done by the Paediatric Committee of the Argentinean Diabetes Association. One DEB sample group and another group without DEB were conformed. HbA1c levels were estimated al baseline and after 3 years. Pubertal stage, BMI, gender and duration of T1D were assessed at the end of the study. Comparison of statistical tests of HbA1c levels and association tests were made. Eighty seven patients, 22 with DEB and 65 without DEB were studied. Patient's mean ages (13.6 vs.14.3 years) and T1D evolution time (4.0 vs. 4.7 years) were similar in both groups. Three years later, there was an increase in the mean HbA1c levels in both groups, with statistical differences only in the DEB group (8.40 vs. 9.93) (p: 0.001), but not in the group without DEB [8.57 vs. 9.01 (p: 0.06)]. An association between metabolic control and the presence of DEB was observed but not with the other studied variables. Presence and persistence DEB in T1D patients implies a worsening prognosis of the metabolic control in the future.

The use of new technologies in rehabilitation, such as virtual reality and/or computerized gaming exercises, may be useful to enable patients to practice intensively in a motivating way. The objective of the present randomized controlled pilot study was to compare the effect of reach training using a target group specific-designed rehabilitation game to time-matched standardized conventional reach training on arm function after stroke. Twenty chronic stroke patients were randomized to either the rehabilitation game group or the conventional training group. Both groups received three arm training sessions of 30 minutes each week, during a period of 6 weeks. Arm (the upper extremity part of Fugl-Meyer [FM] assessment) and hand (the Action Research Arm [ARA] test) functions were tested 1 week before (T0) and 1 week after (T1) training. A follow-up measurement was performed at 1 month after T1 (T2). ARA and FM scores improved significantly within both groups. Post hoc comparisons revealed significant increases in test scores between T0 and T1 and between T0 and T2 for both ARA and FM, but not for changes from T1 to T2. There were no significant differences between both groups for either clinical test. The present randomized controlled pilot study showed that both arm and hand function improved as much after training with a rehabilitation game as after time-matched conventional training.

To evaluate the effects of maxillary canine retraction on pulpal blood flow (PBF) in humans as recorded by laser Doppler flowmetry (LDF). Maxillary canines of 24 participants were divided into two groups (n = 12 each). Teeth in the study group underwent maxillary canine retraction using mini-implants as anchorage for approximately 4 months, with 100 g of force applied via coil springs. Subjects in the control group received no orthodontic treatment. LDF measurements were recorded at baseline (T0); during retraction, at 24 hours (T1), 3 days (T2), 7 days (T3) and 1 month (T4); and at the end of retraction (T5) in the study group and at similar time-points in control subjects. Data were analyzed using the Friedman, Wilcoxon signed rank and Mann-Whitney U tests, with the significance level set at 0.05. No significant changes in PBF perfusion units (PU) were observed in the control group over the course of the study. However, PBF in the study group increased significantly from T0 (3.6 ± 0.2 PU) to T1 (3.7 ± 0.2 PU, p < 0.001) and decreased severely from T1 to T2 (3.3 ± 0.1, p < 0.001). PBF in the study group was still significantly lower at T3 (3.4 ± 0.1 PU, p < 0.001) in comparison to T0; however, at T4 and T5, PBF was found to have returned to pre-retraction levels. The fact that PBF values returned to initial levels within one month of the initiation of retraction despite short-term, hyperaemic, regressive changes demonstrates that the changes observed in PBF during canine retraction are reversible.

Argulosis hampers aquaculture production and alters the host physiology and growth. Azadirachtin is recognized as a potential antiparasitic agent against Argulus sp. The present study aimed to investigate the effect of different concentration of azadirachtin solution on haematological and serum biochemical parameters of Argulus-infested goldfish Carassius auratus. Ninety Argulus-infested goldfish were randomly divided into six equal groups. Fish of group 1-5 were treated with azadirachtin solution through bath of 1, 5, 10, 15 and 20 mg L(-1) as T1, T2, T3, T4 and T5, respectively, and group 6 was exposed to 2% DMSO solution without azadirachtin and considered as negative control T0(-). Along with six treatment groups, a positive control T0(+) of healthy goldfish free from Argulus infestation was also maintained. Parasitic mortality was evaluated after 3 days of consecutive bath treatment. After 7 days of post-treatment, the blood and serum were drawn from each of the treatment groups and haematological and serum biochemical parameters were evaluated. Total leucocyte count (TLC), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), blood glucose, total protein (TP), globulin, serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) were significantly (p < 0.05) high in negative control group when compared with positive control group. It could be concluded that Argulus infestation altered marked haematological and serum biochemical parameters. However, in treated groups complete elimination of Argulus was found in T4 and T5 groups. Also significant (p < 0.05) reduction in haematological and serum biochemical parameters of all the treatment groups were recorded in comparison with negative control group. In addition, T4 and T5 groups showed significantly (p < 0.05) high superoxide dismutase (SOD), catalase, total erythrocyte count (TEC) and haemoglobin (Hb). However, higher mean corpuscular haemoglobin concentration (MCHC), blood glucose and lactate dehydrogenase (LDH) levels in T5 group revealed that higher concentration of azadirachtin have notable effects on activity of vital tissues function and physiology of the host. Argulus spp. from infested goldfish could be eliminated using bath treatment with solution of azadirachtin having concentration of 15 mg L(-1) and that also shifted haematological and serum biochemical parameters towards homeostasis.

Little is known about the changes in autonomic function during spinal anaesthesia in type 2 diabetic patients. The purpose of the study was to assess the influence of spinal anaesthesia on the heart rate variability in type 2 diabetic patients according to the glycated hemoglobin (HbA1c) level. Sixty-six patients who were scheduled for elective orthostatic lower limb surgery were assigned to three groups (n = 22, each) according to HbA1c; controlled diabetes mellitus (HbA1c < 7 %), uncontrolled diabetes mellitus (HbA1c > 7 %) and the control group. The heart rate variability was measured 10 min before (T0), and at10 min (T1), 20 min (T2) and 30 min (T3) after spinal anaesthesia. Before spinal anaesthesia, total, low-and high-frequency power were significantly lower in the uncontrolled diabetec group than in other group (p < 0.05). During spinal anaesthesia, total, low- and high-frequency powers were did not change in the uncontrolled diabetec group while the low-frequency power in the controlled diabetec group was significantly depressed (p < 0.05). The ratio of low-to high-frequency was comparable among the groups, while it was reduced at T1-2 than at T0 in all the groups. The blood pressures were higher in the uncontrolled diabetec group than in the other groups. Spinal anaesthesia had an influence on the cardiac autonomic modulation in controlled diabetec patients, but not in uncontrolled diabetec patients. There were no differences in all haemodynamic variables during an adequate level of spinal anaesthesia in controlled and uncontrolled type 2 DM. ClinicalTrials.gov NCT02137057.

To determine whether an internet-based mentoring program can improve glycemic control in subjects with type 1 diabetes mellitus (T1DM). Subjects with T1DM on intensive insulin therapy and with hemoglobin A1c (HbA1c) ≥8.0% were randomized to mentored (glucometer transmission with feedback from mentors) or control (glucometer transmission without feedback) groups and were examined for 12 weeks. Five mentors were interviewed and selected, of which two were T1DM patients themselves and three were parents with at least one child diagnosed with T1DM since more than 5 years ago. A total of 57 T1DM adult subjects with a mean duration after being diagnosed with diabetes of 7.4 years were recruited from Samsung Medical Center. Unfortunately, the mentored group failed to show significant improvements in HbA1c levels or other outcomes, including the quality of life, after completion of the study. However, the mentored group monitored their blood glucose (1.41 vs. 0.30) and logged into our website (http://ubisens.co.kr/) more frequently (20.59 times vs. 5.07 times) than the control group. A 12-week internet-based mentoring program for T1DM patients with inadequate glycemic control did not prove to be superior to the usual follow-up. However, the noted increase in the subjects' frequency of blood glucose monitoring may lead to clinical benefits.

The objective of this study was to investigate the long-term effect of presurgical nasoalveolar molding (PNAM) on growth of the maxillary arch through early childhood until 6 years of age in complete unilateral cleft lip and palate (UCLP) patients presenting for PNAM at different ages. Complete UCLP patients who were treated at our centre were divided into two groups. The study group underwent PNAM and was further subdivided into three subgroups (PNAM initiated within 1 month, between 1 and 6 months, and between 6 and 12 months of age in subgroup I, II, and III, respectively). The control group did not undergo PNAM and was further subdivided into three subgroups. Patients were evaluated at T1 (first visit), T2 (before cheiloplasty), and T3 (at 6 years). Between T1and T2, the intersegment distance (ISD) reduced significantly in the study group but increased in the control group, whereas the intercanine width (ICW) in both the study and control groups did not show significant change. Between T2 and T3, ISD and ICW were reduced significantly in the control group due to arch collapse, whereas in the study group, ISD reduced slightly with ICW remaining almost similar to noncleft norms. We conclude that reduced ISD following PNAM improves arch symmetry and stability, and thus may prevent arch collapse in the long term.

Evaluate the effectiveness of a diabetes mellitus educational program in primary health care. This cluster randomized trial was conducted in a sample of 470 people with type 2 diabetes mellitus from eight health units, randomly assigned to two groups: intervention (n = 231) and control (n = 239). The intervention group participated in the educational program composed of three strategies: group education, home visit, and telephone intervention. Simultaneously, the control group was monitored individually. Group monitoring took place over nine months in the year 2012. Clinical evaluations were performed at the initial time (T0), three (T3), six (T6) and nine (T9) months after the beginning of the intervention. After nine months of follow-up, 341 users remained in the study, 171 in the control group and 170 in the intervention group. The average age of users was 60.6 years. In both groups, statistically significant differences were observed in mean HbA1c levels over the follow-up time (p < 0.05). However, the mean HbA1c level at T3, T6 and T9 times were significantly lower among the people in the intervention group (p < 0.05). The educational program model developed was effective to improve the glycemic control of the intervention group participants.

This study was to examine the effects of acupressure on fatigue and depression in HCC patients undergoing TACE. A quasiexperimental study design was used. Patients were evaluated at five time points: before treatment (T1) and 2, 3, 4, and 5 days after treating TACE (T2, T3, T4, and T5). Fatigue and depression were assessed by a VAS fatigue scale and a VAS depression scale at each time point. TFRS and BDI were administered at T1 and T5. Patients' fatigue and depression were significantly higher at T5 than at T1 in two groups. Fatigue and depression increased in both the experimental and control groups' patients over the five days of hospitalization during which TACE and chemotherapy were administered. The experimental group had significantly less fatigue than the control group, with lower subscale scores on physical, psychosocial, daily, and overall fatigue. There were no differences between the groups on depression. At posttest, the experimental group experienced lower physical, psychosocial, daily, and overall fatigue than the control group. Acupressure can improve fatigue in HCC patients during treatment with TACE but did not alleviate depression. Discharge planning should include home care for management of fatigue and depression.

The long-term effects of amino acid-based formula (AAF) in the treatment of cow's milk allergy (CMA) are largely unexplored. The present study comparatively evaluates body growth and protein metabolism in CMA children treated with AAF or with extensively hydrolyzed whey formula (eHWF), and healthy controls. A 12-month multicenter randomized control trial was conducted in outpatients with CMA (age 5-12 m) randomized in 2 groups, treated with AAF (group 1) and eHWF (group 2), and compared with healthy controls (group 3) fed with follow-on (if age <12 months) or growing-up formula (if age >12 months). At enrolment (T0), after 3 (T3), 6 (T6), and 12 months (T12) a clinical evaluation was performed. At T0 and T3, in subjects with CMA serum levels of albumin, urea, total protein, retinol-binding protein, and insulin-like growth factor 1 were measured. Twenty-one subjects in group 1 (61.9% boys, age 6.5 ± 1.5 months), 19 in group 2 (57.9% boys, age 7 ± 1.7 months) and 25 subjects in group 3 (48% boys, age 5.5 ± 0.5 months) completed the study. At T0, the weight z score was similar in group 1 (-0.74) and 2 (-0.76), with differences compared to group 3 (-0.17, P < 0.05). At T12, the weight z score value was similar between the 3 groups without significant differences. There were no significant changes in protein metabolism in children in groups 1 and 2. Long-term treatment with AAF is safe and allows adequate body growth in children with CMA.

A feeding trial was conducted for 40 days to delineate the effect of treatment with probiotics as water additives on tilapia (Oreochromis niloticus) growth performance and immune response. About 360 juveniles were randomly distributed into four treatment groups, each with three replicates. Different probiotics (T-1, Bacillus subtilis B10; T-2, Bacillus coagulans B16; T-3, Rhodopseudomonas palustris G06) were added to the water of tanks at final concentration of 1 x 10(7) cfu ml(-1) every 2 days, with no probiotic added to control tanks. At the end of the feeding trial, fish treated with B. coagulans B16 (T-2) and R. palustris G06 (T-3) had significantly (P < 0.05) higher final weight, daily weight gain, and specific growth rate compared with those treated with B. subtilis B10 (T-1) and those without probiotics (control). The highest (P < 0.05) content of total serum protein was found in T-2 compared with that in T-1, T-3, and the control. However, albumin concentration and albumin/globulin ratio were not affected by the probiotics treatments. Compared with the control, probiotic supplementation remarkably improved activities of superoxide dismutase and catalase (P < 0.05). T-2 fish exhibited higher average myeloperoxidase activity than the control, T-1, and T-3 groups. Regarding serum lysozyme content in tilapia, assays showed no difference (P > 0.05) among the treatment groups. Furthermore, probiotics treatments remarkably increased respiratory burst activity compared with control, with T-2 showing higher values than T-1 and T-3. This indicated that treatment with probiotics, B. coagulans B16 and R. palustris G06, as water additives could be used to enhance immune and health status, thereby improving growth performance of O. niloticus.

The aim of this study was to evaluate the efficacy of an intervention combining Life Review Therapy (LRT) and Memory Specificity Training (MST) (LRT-MST) to improve ego-integrity and despair among cancer patients in palliative care. In this multicentre randomized controlled trial, cancer patients in palliative care were randomized to the intervention group (LRT-MST; n = 55) or waiting-list control group (n = 52). LRT-MST is a 4-session home-based psychological intervention that aims to retrieve specific positive memories, to re-evaluate life events and to reconstruct the story of a patient's life, including the diagnosis of incurable cancer. Outcome measures were ego-integrity and despair (NEIS), psychological distress, anxiety and depression (HADS), quality of life (EORTC QLQ-C15-PAL), and specificity of the autobiographical memory (AMT). NEIS, HADS and EORTC QLQ-C15-PAL were assessed at baseline (T0), 1 month later (post-treatment; T1), and at 1 month follow-up (T2). AMT was assessed at T0 and T1. Linear mixed models (intention to treat) were used to assess group differences in changes over time. Independent samples t-tests were used to assess group differences at T0, T1, and T2, and effect sizes (ES) were calculated at T1 and T2. The course of ego-integrity (not despair) improved significantly over time (p = .007) in the intervention group compared to the waiting-list control group, with moderate, but insignificant, effect sizes at T1 (ES = .42) and T2 (ES = .48). Compliance rate was 69% and total dropout rate was 28%, both primarily related to disease progression and death. LRT-MST seems effective among cancer patients in palliative care to improve the course of ego-integrity.

This experiment was designed to investigate the effect of feed supplementation with nano elemental Se (Nano-Se) on growth performance, tissue Se distribution, meat quality, and glutathione peroxidase (GSH-Px) activity in Guangxi Yellow chicken. Four treatments (control, T-1, T-2, and T-3 treatment groups) with 3 replicates of 30 chickens each were carried out. Diets for the control, T-1, T-2, and T-3 groups consisted of the basal diet supplemented with, respectively, 0.00, 0.10, 0.30, and 0.50 mg/kg of Nano-Se. Improved final BW, daily BW gain (DWG), feed conversion ratios, and survival rate (P < 0.05) were observed in the groups supplemented with Nano-Se as compared with the control groups after 90 d of feeding. The groups that received Nano-Se showed higher (P < 0.05) hepatic and muscle Se contents, drip loss percentage, inosine 5'-monophosphate content, and GSH-Px activities in the serum and liver than that did the control groups. For the T-2 and T-3 groups, a significant difference (P < 0.05) was observed in final BW, DWG, muscle Se content, breast drip loss, and GSH-Px activities in the serum and liver compared with the T-1 group. However, no significant differences were observed in final BW, DWG, and GSH-Px activities in the serum and liver between the T-2 and T-3 groups. It could be concluded from this study that supplementing diets with 0.30 mg/kg of Nano-Se for was effective in increasing the growth performance and feed conversion ratios of chickens, the Se content of tissues, and the quality of the meat.

the aim of the study was to evaluate the relationship between type 2 diabetes (T2DM), depression and depressive symptoms and their clinical impact on T2DM. the authors evaluated 214 outpatients, 105 with diabetes (T2DM group) and 109 non-diabetics (control group), with ages ranging between 50 and 75 years (T2DM group 65.1 ± 5.6 years, control group 63.4 ± 5.8 years). Use of antidepressant treatment or score ≥ 16 on the Beck depression inventory (BDI) was considered depression. Complications of diabetes and total symptom score (TSS) for peripheral neuropathy were reported by patients. diabetes group had a higher frequency of depression (35.2%) compared to controls (21.1%) (p=0,021), with 2.4 times increased risk of depression. The presence of depressive symptoms was also higher in T2DM group (mean BDI 9.5 ± 8.8 versus 6.9 ± 6.2; p=0.039). Symptoms of diabetic neuropathy were higher in depressed subjects. The metabolic control and presence of complications in T2DM group were not associated with depression. T2DM led to an increased risk of depression, but this did not influence the metabolic control or the presence of other complications.

In this present investigation, flow cytometry was utilized to evaluate 13 healthy controls and 31 HIV-1 infected patients who had advanced to the AIDS stage of infection (CD4 count below 200 cells/mm(3)), for the expression of CD161 on CD3(+) double negative (DN) (CD3(+)CD4(-)CD8(-)) T cells, CD4(+) T cells, CD8(+) T cells and γδ T cells. The observed depletion of CD161(+) T cells from peripheral circulation was due primarily to the loss of CD4(+)CD161(+) T cells; as these cells represented 8.67±0.74% of the total healthy control peripheral T cell population, while the CD4(+)CD161(+) T cells of the AIDS group represented only 3.35±0.41% (p=<0.0001) of the total peripheral T cell population. We have also shown here that the DN T cell population was more than doubled in the AIDS group, with the DN T cell population expanding from 3.29±0.45% of the healthy control peripheral T cell population to 8.64±1.16% (p=0.0001) of the AIDS group peripheral T cell population. By evaluating the expression of CD161 on the surface of the DN T cells we showed that within the healthy control group, 47.4±4.99% of the DN T cells were positive for the expression of CD161, while only 26.4±3.54% (p=0.002) of the AIDS group's DN T cells expressed CD161. Despite CD161 expression being halved on the DN T cells of the AIDS group, when we compared the total peripheral T cell percentage of CD161(+) DN T cells between the healthy control group and the AIDS group, there was no statistical difference. Even though only 26.4% DN T cells within the AIDS group were positive for CD161(+), the overall DN T cell population had expanded to such an extent that there was no statistical difference between the groups with regard to CD161(+) DN T cells as a percentage of the total peripheral T cell population. Furthermore, we showed that within the DN T cell population, there was an approximate 2:1 ratio of γδ to αβ T cells, and this ratio was maintained in both the healthy control group and the AIDS group. While evaluating γδ T cells we also discovered that CD8(+) γδ T cells were expanded from 0.62±.09% of the healthy control peripheral T cell population to 5.01±.88% (p=<0.0001) of the peripheral T cell population of the AIDS group; and that this population of CD8(+) γδ T cells underwent the same reduction in percentage of cells expressing CD161(+), further demonstrated that the phenomenon of CD161(+) percentage reduction and compensatory increase in total cell population was affecting the entire circulating γδ T cell population.

This is the first study to investigate the completely anti-atherogenic effect of Deglet Noor Date seeds methanol extract administration on diet-induced hypercholesterolemic rats. About 24 male Wistar rats were divided into 6 groups. The normal control (NC) group, Hypercholesterolemic Control (HC) group was given high cholesterol diet, and Simvastatin Control (SC) group was given 0.18 mg/200g simvastatin after high cholesterol diet induction. The treatment groups of T0.25, T0.5 and T1 were given supplementation of 0.25, 0.5 and 1 g/kg of dates seed extract after high cholesterol diet induction, respectively for 21 days. Blood was collected from orbitals plexus vein for plasma lipid profile analysis. The levels of Total Cholesterol (TC), Low-Density Lipoprotein (LDL) and Atherogenic Index (AI) values were significantly decreased (p<0.05) on diet-induced hypercholesterolemic rats after supplemented with date seeds extract (T0.25, T0.5 and T1) but not in Triglycerides (TG). Along with that, High Density Lipoprotein (HDL) level was significantly increased (p<0.05). However, the T1 group was the best anti-atherogenic activity in compared to other groups. Results showed that plasma lipid profile was significant to get better after supplemented with date seeds extract.

Quantitative mapping of T1 relaxation in the rotating frame (T1ρ) is a magnetic resonance imaging technique sensitive to pH and other cellular and microstructural factors, and is a potentially valuable tool for identifying brain alterations in bipolar disorder. Recently, this technique identified differences in the cerebellum and cerebral white matter of euthymic patients vs healthy controls that were consistent with reduced pH in these regions, suggesting an underlying metabolic abnormality. The current study built upon this prior work to investigate brain T1ρ differences across euthymic, depressed, and manic mood states of bipolar disorder. Forty participants with bipolar I disorder and 29 healthy control participants matched for age and gender were enrolled. Participants with bipolar disorder were imaged in one or more mood states, yielding 27, 12, and 13 imaging sessions in euthymic, depressed, and manic mood states, respectively. Three-dimensional, whole-brain anatomical images and T1ρ maps were acquired for all participants, enabling voxel-wise evaluation of T1ρ differences between bipolar mood state and healthy control groups. All three mood state groups had increased T1ρ relaxation times in the cerebellum compared to the healthy control group. Additionally, the depressed and manic groups had reduced T1ρ relaxation times in and around the basal ganglia compared to the control and euthymic groups. The study implicated the cerebellum and basal ganglia in the pathophysiology of bipolar disorder and its mood states, the roles of which are relatively unexplored. These findings motivate further investigation of the underlying cause of the abnormalities, and the potential role of altered metabolic activity in these regions. © 2018 John Wiley & Sons A/S.

Overt hypothyroidism is frequently found in patients with type 2 diabetes mellitus (T2DM), but it remains unknown the relationship between subclinical hypothyroidism (SCH) and T2DM. We attempt to evaluate the difference in prevalence of SCH between patients with T2DM and general population, and the association between SCH and glycemic control status ofdiabetic patients. This was cross-sectional study. Total 8,528 subjects who visited for health check-up were recruited. SCH was defined as an elevated level of serum thyroid stimulating hormone (> 4.0 mIU/L) with a normal level of free thyroxine. T2DM group was categorized into three groups by glycosylated hemoglobin (HbA1c): < 7% (reference), ≥ 7% and < 9%, ≥ 9%. Finally, 7,966 subjects were included. The prevalence of SCH was not different between healthy controls and subjects with T2DM (8.1% vs. 7.4%, p = 0.533; in men, 5.7% vs. 5.1%, p = 0.573; in women, 10.9% vs. 11.7%, p = 0.712), but it was increased with highest HbA1c group more than well controlled group, especially in women. The risk of SCH was increased by group with poorer glycemic control; the odds ratio for HbA1c ≥ 9% compared to < 7% was 2.52 (95% confidence interval [CI], 1.09 to 5.86; p = 0.031), and 4.58 (95% CI, 1.41 to 14.87; p = 0.011) in women, but not significant in men. The prevalence of SCH was similar between T2DM and healthy group. Poor glycemic control in T2DM was obviously associated with the risk of SCH, especially in elderly women. These results suggest SCH as comorbidity may be considered in elderly women with poor glycemic control.

The consequences of subclinical coeliac disease (CD) in Type 1 diabetes mellitus (T1DM) remain unclear. We looked at growth, anthropometry and disease management in children with dual diagnosis (T1DM + CD) before and after CD diagnosis. Anthropometry, glycated haemoglobin (HbA1c) and IgA tissue transglutaminase (tTg) were collected prior to, and following CD diagnosis in 23 children with T1DM + CD. This group was matched for demographics, T1DM duration, age at CD diagnosis and at T1DM onset with 23 CD and 44 T1DM controls. No differences in growth or anthropometry were found between children with T1DM + CD and controls at any time point. Children with T1DM + CD, had higher BMI z-score two years prior to, than at CD diagnosis (p < 0.001). BMI z-score change one year prior to CD diagnosis was lower in the T1DM + CD than the T1DM group (p = 0.009). At two years, height velocity and change in BMI z-scores were similar in all groups. No differences were observed in HbA1c between the T1DM + CD and T1DM groups before or after CD diagnosis. More children with T1DM + CD had raised tTg levels one year after CD diagnosis than CD controls (CDx to CDx + 1 yr; T1DM + CD: 100% to 71%, p = 0.180 and CD: 100% to 45%, p < 0.001); by two years there was no difference. No major nutrition or growth deficits were observed in children with T1DM + CD. CD diagnosis does not impact on T1DM glycaemic control. CD specific serology was comparable to children with single CD, but those with dual diagnosis may need more time to adjust to gluten free diet.

To assess the benefit of isokinetic strengthening of the upper limb (UL) in patients with chronic stroke as compared to passive mobilization. Randomized blinded assessor controlled trial. Physical Medicine and Rehabilitation departments of 2 university hospitals. Patients (N=20) with incomplete hemiplegia (16 men; mean age, 64y; median time since stroke, 32mo). A 6-week comprehensive rehabilitation program, 3d/wk, 3 sessions/d. In addition, a 45-minute session per day was performed using an isokinetic dynamometer, with either isokinetic strengthening of elbow and wrist flexors/extensors (isokinetic strengthening group) or passive joint mobilization (control group). The primary endpoint was the increase in Upper Limb Fugl-Meyer Assessment (UL-FMA) score at day 45 (t1). Secondary endpoints were increases in UL-FMA scores, Box and Block Test scores, muscle strength, spasticity, and Barthel Index at t1, t2 (3mo), and t3 (6mo). Recruitment was stopped early because of excessive fatigue in the isokinetic strengthening group. The increase in UL-FMA score at t1 was 3.5±4.4 in the isokinetic strengthening group versus 6.0±4.5 in the control group (P=.2). Gains in distal UL-FMA scores were larger (3.1±2.8) in the control group versus 0.6±2.5 in the isokinetic strengthening group (P=.05). No significant group difference was observed in secondary endpoints. Mixed models confirmed those results. Regarding the whole sample, gains from baseline were significant for the UL-FMA at t1 (+4.8; P<.001), t2, and t3 and for the Box and Block Test at t1 (+3; P=.013) and t2. In a comprehensive rehabilitation program, isokinetic strengthening did not show superiority to passive mobilization for UL rehabilitation. Findings also suggest a sustained benefit in impairments and function of late UL rehabilitation programs for patients with stroke. Copyright © 2017 American Congress of Rehabilitation Medicine.

Previously, we reported that ChondorT showed significant anti-arthritis and anti-inflammatory effects. ChondroT, a new herbal medication, consists of the water extracts of Osterici Radix, Lonicerae Folium, Angelicae Gigantis Radix, Clematidis Radix, and Phellodendri Cortex (6:4:4:4:3). The objective of this study was to investigate the effects of ChondroT in collagenase-induced osteoarthritis rat model. Osteoarthritis was induced by the injection of collagenase into the right knee joint cavity of rats. The samples were divided into seven groups [intact (n = 6), control (n = 6), indomethacin (n = 6), Joins tab (n = 6), ChondroT50 (n = 6), ChondroT100 (n = 6), and ChondroT200 (n = 6)]. The control group was administered normal saline, indomethacin group was administered indomethacin (2 mg/kg), and Joins tab group was administered Joins Tab (20 mg/kg). The ChondroT50, ChondroT100, and ChondroT200 groups were administered 50, 100, and 200 mg/kg of ChondroT, respectively. All oral administrations were initiated 7 days after the induction of arthritis and were continued for a total of 12 days. At the end of the experiment, serum aminotransferase, albumin, blood urea nitrogen, creatinine, leukocyte, and inflammatory cytokines [tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6] were analyzed. Hematoxylin and eosin (H&E) and safranin O-fast green staining of the articular structures of the knee joint were performed. TNF-α and IL-1β decreased in the ChondroT100 and ChondroT200 groups compared with those in the control group. IL-6 and aspartate aminotransferase decreased in the ChondroT50, ChondroT100, and ChondroT200 groups compared with that in the control group. Albumin, WBC and lymphocytes decreased in the ChondroT100 and ChondroT200 groups compared with those in the control group. In H&E stain, synoviocytes, cartilage lacunae, and chondrocytes were well preserved in the ChondroT100 and ChondroT200 groups, and safranin O-fast staining showed a clear reaction of proteoglycans in the ChondroT100 and ChondroT200 groups. Based on these results, it can be proposed that ChondroT has anti-osteoarthritic effects on collagenase-induced rat model.

The aim of this study was to determine whether psychosocial stimulation up to the age of 2 years benefits cognition and behaviour at age 6 years in low-birthweight, term-born (LBW-T) children (gestational age > or =37 wk, birthweight <2500g), and to compare LBW-T and normal-birthweight (NBW) children. LBW-T Jamaican infants were randomized at birth to a control group or an intervention group. Children in the intervention group received psychosocial stimulation for 2 years. LBW-T infants were also compared with NBW infants born in the same hospital. IQ, cognitive function, and behaviour were measured at age 6 years in 109 LBW-T infants. The LBW-T group were divided into the intervention group (55 out of 70 enrolled, 32 females, 23 males; mean birthweight 2190g, SD 200g; and the control group (54 out of 70 enrolled, 33 females, 21 males; birthweight 2240g, SD 180g]. These were compared with 73 out of 94 enrolled NBW infants (38 females 35 males; birthweight 3130g, SD 330g). Among the LBW-T children performance IQ scores were higher in the intervention group than in the control group (regression coefficient [B] 4.06, 95% confidence interval [CI] 0.01-7.98) as were visual-spatial memory scores (B 1.12, 95% CI 0.45-1.87). Children in the intervention group also exhibited fewer behavioural difficulties (B -2.21, 95% CI -4.13 to -0.10) than children in the control group. Compared with NBW children, LBW-T children in the control group had poorer selective attention (B=-3.35, 95% CI -5.59 to -1.26) and visual-spatial memory (B=-0.76, 95% CI -1.54 to 0.00), but there were no differences in IQ, language, or behaviour. Stimulation had sustained benefits in LBW-T infants. Finding few differences between LBW-T and NBW school-aged children concurs with results from other developing countries.

Background The main aim of this pilot study was to investigate an advanced version of eye movement desensitization and reprocessing (EMDR) for reducing anxiety. Methods Fifty participants were asked at two times of measurement (T1 and T2 with a rest of 4 weeks) to generate anxiety via the recall of autobiographical memories according to their anxiety. Furthermore, the participants were randomly assigned to an experimental group and a control group, and the experimental group received an intervention of 1–2 h with the advanced version of EMDR in order to their anxiety 2 weeks after T1. At T1 as well as T2, we measured the intensity of participants' anxiety with a Likert scale (LS) and collected participants' state (temporary) and trait (chronic) anxiety with the State-Trait Anxiety Inventory (STAI). In addition, we measured participants' physical performance in a test for the finger musculature under the induction of their anxiety. Results The results showed that participant's ratings of their perceived intensity of anxiety (measured by a 9-point LS) and the state and trait anxiety decreased significantly in the experimental group but not in the control group from T1 to T2. Moreover, the physical performance under the induction of participants' anxiety increased significantly in the experimental group from T1 to T2 and there were no significant changes in the control group. Conclusions The study could show that the advanced version of EMDR is an appropriate method to reduce anxiety. PMID:24944864

To investigate the relationship of four single nucleotide polymorphism (SNP) haplotypes in the angiotensinogen (AGT) gene to the primary hypertension with or without cerebral infarction in the Li nationality of Hainan, China. Total 300 subjects were allocated into three different groups: Group 1, 100 patients who have primary hypertension; Group 2, 100 patients who have primary hypertension with cerebral infarction; and control group, 100 healthy individuals. The genotypes of all subjects were determined by PCR-sequencing to analyze the four polymorphisms at position -152 (G-A), -20 (A-C), -18 (C-T), and -6 (A-G) in the promoter region of AGT. The frequencies of CT genotype of AGT-18 and T allele in Group 1 (P = 0.003, P = 0.004) and Group 2 (P = 0.002, P = 0.002) were both significantly higher than in healthy controls. The frequency of G allele of AGT-6 was significantly higher in Group 2 than in the control group (P = 0.016), while there is no significant difference between Group 1 and the control. Haplotype analysis revealed that H6 haplotype frequency which included -20C and -6G was significantly increased in Group 2 (P = 0.003) compared with the control group, while H5 haplotype frequency which included -20C and -18T was significantly increased in Group 1 (P = 0.006) versus the control. The -20 (A-C) and -18 (C-T) of the AGT may play an important role in pathogenesis of primary hypertension; and -20 (A-C), -18 (C-T), and -6 (A-G) may be the genetic risk factors for the onset of primary hypertension with cerebral infarction in the Li nationality of Hainan, China.

Scapular dyskinesis in pitchers can potentially lead to impairments in the optimal performance of muscles of the shoulder complex. The purpose of this prospective study was to evaluate whether the use of a scapula stabilizing t-shirt can decrease stress and discomfort in over-head baseball pitchers. Thirty-two semi-professional baseball pitchers were divided into 2 groups. Group A dressed the scapula stabilizing t-shirt during the weekly practice while group B (control group) continued to follow their training program without the t-shirt. All pitchers underwent a clinical examination at the beginning of the study (T0), 4 weeks (T1) and 8 weeks after (T2). Data collected showed a better clinical outcome at T1 which increased in T2 for pitchers in Group A, while in Group B athletes these positive results were not observed. This study underlines that scapula-stabilizing t-shirt can have positive effects on shoulder discomfort in over-head athletes.

The purpose of the research was to evaluate cervical sagittal parameters on magnetic resonance imaging (MRI) in patients with Modic changes and its impact on axial neck pain. This study consisted of 266 consecutive asymptomatic or symptomatic patients with Modic changes, whose average age was 50.9±12.6 years from January 2015 to December 2016. Cervical sagittal parameters included sagittal alignment of the cervical spine (SACS), T1 slope, thoracic inlet angle (TIA), and neck tilt (NT). The Modic changes group was compared with an asymptomatic control group of 338 age- and gender-matched adults. In the Modic changes group, T1 slope was significantly higher (25.8°±6.3°) compared with that in the control group (22.5°±6.8°) ( P =0.000). However, there was no significant difference of the NT, TIA, and SACS between the two groups. Patients in the Modic changes group were more likely to have experienced historical axial neck pain compared with the control group ( P =0.000). With regard to the disc degeneration, it indicated that the disc in the Modic changes group had more severe disc degeneration ( P =0.032). T1 slope in the Modic changes group was significantly higher compared to that of the control group. The findings suggested that a higher T1 slope with broken compensation of cervical sagittal mechanism may be associated with the development of Modic changes in the cervical spine.

To observe the clinical effect of ear point embedding on plasma and effect site concentrations of propofol-remifentanil in elderly patients who underwent abdominal external hernia surgery at the time of consciousness and pain disappearing by target-controlled infusion (TCI) and bispectral index (BIS). Fifty patients who underwent elective abdominal hernia surgery were randomly assigned into an observation group and a control group, 25 cases in each one. In the observation group, 30 minutes before anesthesia induction, Fugugou (Extra), Gan (CO 12 ), Pizhixia (AT 4 ), and Shenmen (TF 4 ) were embedded by auricular needles until the end of surgery, 10 times of counter press each point. In the control group, the same amount of auricular tape was applied until the end of surgery at the same points without stimulation 30 minutes before anesthesia induction. Patients in the two groups were given total intravenous anesthesia, and BIS was monitored by BIS anesthesia depth monitor. Propofol was infused by TCI at a beginning concentration of 1.5μg/L and increased by 0.3μg/L every 30s until the patients lost their consciousness. After that, remifentanil was infused by TCI at a beginning concentration of 2.0μg/L and increased by 0.3μg/L every 30s until the patients had no body reaction to pain stimulation (orbital reflex). Indices were recorded, including mean arterial pressure (MAP), heart rate (HR) and the BIS values, at the time of T 0 (entering into the operation room), T 1 (losing consciousness) and T 2 (pain relief), the plasma and effect site concentrations of propofol at T 1 , the plasma and effect site concentrations of remifentanil at T 2 . After surgery we recorded the total amounts of propofol and remifentanil, surgery time and anesthesia time. At T 1 and T 2 , MAP and HR of the observation group were higher than those of the control group ( P <0.05, P <0.01). At T 1 , the plasma and effect site concentrations of propofol in the observation group were significantly lower than those in the control group ( P <0.05, P <0.01). At T 2 , the plasma and effect site concentrations of remifentanil in the observation group were significantly lower than those in the control group ( P <0.05, P <0.01). There was no significant difference in BIS values at T 1 and T 2 between the two groups (both P >0.05). There was no significant difference in operation time and anesthesia time between the two groups (both P >0.05). The total amount of remifentanil in the observation group was significantly lower than that in the control group ( P <0.01). There was no significant difference in the total amount of propofol between the two groups ( P >0.05). Ear points embedding combined with propofol-remifentanil TCI could reduce the plasma and effect site concentrations of propofol and remifentanil and the total amount of remifentanil in elderly patients with extra-abdominal hernia surgery, and had the effect of assisting sedation and analgesia.

Suppressive or replacement doses of levothyroxine (LT4) are affected by the rate and extent of the active ingredient absorbed, as well as by the lean body mass. Obesity has reached epidemic proportions worldwide and is related with many comorbidities. The aim of this study was to determine the pharmacokinetic parameters of LT4 in severely obese individuals and compared them with similar data in lean control subjects. We studied 62 euthyroid subjects who had negative tests for anti-thyroid peroxidise antibodies (Ab-TPO). Thirty eight of these subjects were severely obese but otherwise healthy (severe obese subjects [SOS] group). Twenty-four were healthy control subjects (control group), with a body mass index of 23.3 ± 1.7 kg/m(2). Subjects received 600 μg oral sodium LT4 after an overnight fast. Serum triiodothyronine (T3), T4, and thyroid-stimulating hormone were measured at baseline. Serum T4 and T3 was measured 0.5, 1, 1.5, 2, 2.5, 3, and 4 hours after LT4 administration. Baseline serum T4 and thyroid-stimulating hormone concentrations were higher in the SOS group than in the control group; serum T3 was similar in the two groups. The corrected area under the curve and the maximum T4 concentration after LT4 administration were lower, whereas the time to maximum concentration from the baseline was higher in SOS than in the control group. The estimated plasma volume was higher in the SOS than in the control group. Mean serum T3 levels increased gradually during the four hours after LT4 administration in the control group. In contrast, they decreased gradually in the SOS group. Severely obese individuals may need higher LT4 suppressive or replacement doses than normal-weight individuals due, among other factors, to impaired LT4 pharmacokinetic parameters. The latter could be attributed to their higher plasma volume and/or to delayed gastrointestinal LT4 absorption. T4 conversion to T3 might be defective in severe obesity.

Toxoplasma gondii is the causative parasite of an important worldwide disease. This obligate intracellular parasite can infect and replicate inside any nucleated cells including those of pancreas. Insulin is a hormone secreted by the pancreas and is responsible for controlling blood glucose concentration. Deficiency of insulin production accounts for the occurrence of type-1 diabetes mellitus (T1D). Thus, theoretically, toxoplasmosis could play a possible role in the development of T1D. However, the studies on this theory are still insufficient; therefore, this work was designed. Interestingly, in the case-control study, seropositivity of anti-Toxoplasma IgG was significantly higher among T1D (86.37%) in comparison with T2D (66.67%) and the control group (60%). Moreover, the odd ratio of chronic toxoplasmosis was 4.2 folds higher among T1D patients than among controls. The experimental study included acute and chronic Me49 T. gondii infected mice groups in addition to a control group. Pathological examination revealed the presence of T. gondii zoites adjacent to the islets of Langerhans and in pancreatic parenchyma of acutely infected mice. With chronic infection, there was a significant reduction of islets number and sizes in association with grade-1 insulitis. Additionally, the immunohistochemical study showed significant infiltration of the islets of chronically infected mice by CD8 + and CD45 + immune cells. In contrary to the control group, the islets of the chronic group showed significantly higher expression of the apoptotic marker caspase-3 and a significantly lower expression of the proliferation marker Ki69. Finally, a significant reduction of insulin expression in the islets of chronic infection group was detected in association with a significant increase in serum glucose concentrations; however, the establishment of diabetes did not occur throughout this work. Thus, this study presents an evidence for the probable role of chronic toxoplasmosis in the development of T1D which should be considered in further studies. Copyright © 2018 Elsevier Inc.

Transforming growth factor-β1 (TGF-β1) is an important fibrogenic and immunomodulatory cytokine participating in the pathogenesis of a number of illnesses related to the growth, differentiation and migration of cells. It also plays a key role in inflammation, atherosclerosis, vascular inflammation and asthma. The aim of the present study was to evaluate the association between the expression of the TGF-β1 gene and its genetic polymorphisms, and the disease phenotype. The study comprised 173 patients with asthma, as well as 163 healthy volunteers as a control group. The gender profiles of the groups were similar (p=0.8415). Genotyping was performed by polymerase chain reaction (PCR)-high resolution melting (HRM). The results were verified by sequencing. Gene expression was evaluated by RT-PCR. This study evaluated the role and frequency of genetic polymorphisms (C-509T, C+466T and T+869C) of the TGF-β1 gene in the study group (patients with asthma) and the control group (healthy volunteers). The results obtained for the patients and healthy controls were as follows: C-509T single nucleotide polymorphism (SNP) (controls, TT/CT/CC-0.4444/0.5309/0.0247; patients, TT/CT/CC-0.3699/0.6012/0.0289), C+466T SNP (controls, TT/CT/CC-1.000/0.000/0.000; patients, TT/CT/CC-1.000/0.000/0.000) and T+869C SNP (controls, TT/CT/CC-1.000/0.000/0.000; patients, TT/CT/CC-1.000/0.000/0.000). Only the C-509T polymorphism was found to play a significant role in the pathogenesis of asthma, as well as a risk factor in the loss of the clinical control of the disease [TT vs. CC/CT, odds ratio (OR) 2.38; confidence interval (CI) 1.22-4.66; p=0.0103]. A significant difference was noted between the study and control groups with regard to the mRNA expression of TGF-β1 (p=0.0133). A higher level of expression of the TGF-β1 gene correlated with the time of diagnosis of patients over 16 years of age (p=0.0255). This study demonstrates that the C-509T SNP is a significant clinical risk factor for asthma and that the TGF-β1 cytokine contributes to the progression of the illness.

Rajyoga meditation is a form of mind body intervention that is promoted by the Brahma Kumaris World Spiritual University. This form of meditation can be easily performed without rituals or mantras and can be practiced anywhere at any time. The practice of Rajyoga meditation can have beneficial effects on modulating anxiety and cortisol level in patients undergoing major cardiac surgery. A prospective randomized control study was carried out in a single tertiary care center. One hundred and fifty patients undergoing elective coronary artery bypass surgery were enrolled in the study. The patients were randomized in two groups namely, Group 1 (Rajyoga group) and Group 2 (Control Group). Anxiety was measured on a visual analog scale 1-10 before the start of Rajyoga training or patient counseling (T1), on the morning of the day of surgery (T2), on the 2nd postoperative day (T3), and on the 5th postoperative day (T4). The serum cortisol level was measured in the morning of the day of surgery (T1), on the 2nd postoperative day (T2) and on the 5th postoperative day (T3), respectively. In the study, it was seen that the anxiety level of the patients before the surgery (T1) and on the day of surgery (T2) were comparable between the two groups. However on the 2nd postoperative day (T3), the patients who underwent Rajyoga training had lower anxiety level in comparison to the control group (3.12 ± 1.45 vs. 6.12 ± 0.14, P < 0.05) and on the 5th postoperative day (T4) it was seen that Rajyoga practice had resulted in significant decline in anxiety level (0.69 ± 1.1 vs. 5.6 ± 1.38, P < 0.05). The serum cortisol level was also favorably modulated by the practice of Rajyoga meditation. Mindbody intervention is found to effective in reducing the anxiety of the patients and modulating the cortisol level in patients undergoing wellknown stressful surgery like coronary artery bypass surgery.

ABSTRACT OBJECTIVE Evaluate the effectiveness of a diabetes mellitus educational program in primary health care. METHODS This cluster randomized trial was conducted in a sample of 470 people with type 2 diabetes mellitus from eight health units, randomly assigned to two groups: intervention (n = 231) and control (n = 239). The intervention group participated in the educational program composed of three strategies: group education, home visit, and telephone intervention. Simultaneously, the control group was monitored individually. Group monitoring took place over nine months in the year 2012. Clinical evaluations were performed at the initial time (T0), three (T3), six (T6) and nine (T9) months after the beginning of the intervention. RESULTS After nine months of follow-up, 341 users remained in the study, 171 in the control group and 170 in the intervention group. The average age of users was 60.6 years. In both groups, statistically significant differences were observed in mean HbA1c levels over the follow-up time (p < 0.05). However, the mean HbA1c level at T3, T6 and T9 times were significantly lower among the people in the intervention group (p < 0.05). CONCLUSIONS The educational program model developed was effective to improve the glycemic control of the intervention group participants. PMID:29412378

The research was conducted by a pretest and post-test conducted in a quasi-experimental design which aimed to determine effectiveness of Aggression Replacement Training (ART) on problem solving, anger and aggressive behaviour among adolescents with criminal attempts in Turkey. The study included 65 adolescents with criminal attempts (32 intervention, 33 control). There was no difference between the groups in terms of average age (16.13±1.10 in the experimental group and 16.21±0.89 in the control group). After the intervention, the experimental group showed significantly decreased Trait Anger levels (t=1.906; P=0.033), increased Anger Control scores (t=2.522; P=0.008), decreased Physical Aggression scores (t=1.925; P=0.031), decreased Hostility scores (t=2.496; P=0.009), increased Social Problem Solving total scores (t=2.937; P=0.005). Increased Anger Control scores were found to be significant when compared with the control group (t=2.273, P=0.026). These results showed that ART was effective on problem solving, anger and aggressive behaviour and can be used to develop positive behaviours among adolescents with criminal attempts.

Background The superiority of an intervention combining two sets of theory-based behavior change techniques targeting planning and self-efficacy over an intervention targeting planning only or self-efficacy only has rarely been investigated. Purpose We compared the influence of self-efficacy, planning, and self-efficacy+planning interventions with an education-based control condition on adolescents’ body fat, assuming mediating effects of respective social cognitive variables and moderate-to-vigorous physical activity (MVPA). The moderating role of the built environment was examined. Methods Participants (N = 1217, aged 14–18 years) were randomly assigned to four conditions: planning (n = 270), self-efficacy (n = 311), self-efficacy+planning (n = 351), and control (n = 285). The measurement was conducted at baseline (T1), two-month follow-up (T2), and fourteen-month follow-up (T3). Interventions/control group procedures were delivered at T1 and T2. Percent of body fat tissue (measured at T1 and T3) was the main outcome. Social cognitive mediators (self-efficacy and planning) were assessed at T1 and T2. The behavioral mediator (MVPA) and the presence of built MVPA facilities (the moderator) were evaluated at T1 and T3. Results Similar small increases of body fat were found across the three intervention groups, but the increment of body fat was significantly larger in the control group. On average, differences between control and intervention groups translated to approximately 1% of body fat. Effects of the interventions on body fat were mediated by relevant social cognitive variables and MVPA. A lower increase of body fat was found among intervention group participants who had access to newly-built MVPA facilities. Conclusions We found no superiority of an intervention targeting two social cognitive variables over the intervention targeting one cognition only. PMID:27410961

The aim of this randomized and controlled trial was to investigate the effect of a glucose-insulin-potassium (GIK) solution on myocardial protection in acute coronary syndrome (ACS) patients undergoing urgent multivessel off-pump coronary artery bypass (OPCAB) surgery. Sixty-six patients were randomly allocated either to receive 0.3 ml kg(-1) h(-2) GIK solution (potassium 80 mEq and regular insulin 325 IU in 500 ml of 50% glucose) or equivalent volume of normal saline (control) upon anaesthetic induction until 6 h after reperfusion. The primary endpoints were to compare the concentrations of creatine kinase-MB (CK-MB) and troponin-T between the groups after reperfusion. The secondary endpoints were to compare the incidences of postoperative troponin-T >0.8 ng ml(-1) and myocardial infarction (MI) between the groups. Highest CK-MB [8.7 (4.4) vs 13.1 (7.9) ng ml(-1), P=0.006] and troponin-T [0.20 (0.13-0.49) vs 0.48 (0.18-0.91) ng ml(-1), P<0.0001] values after reperfusion were significantly lower in the GIK group compared with the control group. The area under the curve of serially measured troponin-T was also significantly smaller in the GIK group compared with the control group [0.83 (0.43-1.81) vs 0.46 (0.31-1.00), P=0.036]. Significantly fewer patients in the GIK group showed troponin-T >0.8 ng ml(-1) after reperfusion compared with the control group (3 vs 11, P=0.033). The incidence of postoperative MI was similar between the groups. GIK administration in ACS patients undergoing urgent multivessel OPCAB significantly attenuated the degree of ensuing myocardial injury without complications related to glycaemic control.

Objectives To identify the possible role of natural killer (NK) cells in the pathogenesis of type 1 diabetes mellitus (T1DM) through studying the expression of the KLRC3 gene, which encodes the NK cell activating receptor (NKG2E). Methods This study was conducted at Alexandria University Children’s Hospital from April to October 2015. The study was conducted with 30 newly diagnosed T1DM patients (15 males and 15 females), aged 7–13 years (10.6±1.8 years) and 20 non-diabetic subjects served as age- and sex-matched controls. The patients were further sub-divided into two groups; group I included patients who first presented with classical symptoms of DM (polyuria, polydipsia, and polyphagia) without diabetes ketoacidosis (DKA) and group II included patients who first presented with DKA. The expression of the KLRC3 gene was measured in each group using the real-time polymerase chain reaction. Results KLRC3 gene expression was significantly downregulated in T1DM cases compared to healthy controls (p = 0.001). Expression was more downregulated in group I patients (p = 0.008). Moreover, there was higher mean value of glycated heamoglobin and lower C-peptide levels in group I than group II. Serum pancreatic amylase showed no significant difference between the two groups. Conclusions KLRC3 gene expression was downregulated in patients with T1DM compared to healthy controls. Downregulation of expression was greater in DKA patients compared to those who presented with classical symptoms. Expression of KLRC3 in T1DM might play a role in the pathogenesis of T1DM and could be a predictor of its severity. PMID:28804584

This study aimed to investigate the effect of EBI3 on radiation-induced immunosuppression of cervical cancer HeLa cells by regulating Treg cells through PD-1/PD-L1 signaling pathway. A total of 43 adult female Wistar rats were selected and injected with HeLa cells in the caudal vein to construct a rat model of cervical cancer. All model rats were randomly divided into the radiotherapy group ( n = 31) and the control group ( n = 12). The immunophenotype of Treg cells was detected by the flow cytometry. The protein expressions of EBI3, PD-1, and PD-L1 in cervical cancer tissues were tested by the streptavidin-peroxidase method. HeLa cells in the logarithmic growth phase were divided into four groups: the blank, the negative control group, the EBI3 mimics group, and the EBI3 inhibitors group. Western blotting was used to detect PD-1 and PD-L1 protein expressions. MTT assay was performed to measure the proliferation of Treg cells. Flow cytometry was used to detect cell cycle and apoptosis, and CD4 + /CD8 + T cell ratio in each group. Compared with before and 1 week after radiotherapy, the percentages of CD4 + T cells and CD8 + T cells were significantly decreased in the radiotherapy group at 1 month after radiotherapy. Furthermore, down-regulation of EBI3 and up-regulation of PD-1 and PD-L1 were observed in cervical cancer tissues at 1 month after radiotherapy. In comparison to the blank and negative control groups, increased expression of EBI3 and decreased expressions of PD-1 and PD-L1 were found in the EBI3 mimics group. However, the EBI3 inhibitors group had a lower expression of EBI3 and higher expressions of PD-1 and PD-L1 than those in the blank and negative control groups. The EBI3 mimics group showed an increase in the optical density value (0.43 ± 0.05), while a decrease in the optical density value (0.31 ± 0.02) was found in the EBI3 inhibitors group. Moreover, compared with the blank and negative control groups, the apoptosis rates of Treg/CD4 + T/CD8 + T cells were decreased in the EBI3 mimics group, but the EBI3 inhibitors group exhibited an increase in apoptosis rate. In conclusion, over-expression of EBI3 could reduce the apoptosis of Treg/CD4 + T/CD8 + T cells and prevent radiation-induced immunosuppression of cervical cancer HeLa cells by inhibiting the activation of PD-1/PD-L1 signaling pathway.

To investigate the inhibitory mechanisms of testosterone (T) biosynthesis in rats exposed to dibutyl phthalate (DBP). Male Wistar rats were randomly divided into five groups by weight, including 0.25, 0.50, 1.00, 2.00 g/kg DBP groups and corn oil control group, with 16 rats in each group. DBP was administered by gavage once a day. After 30 days exposure, eight rats in each group were killed and the others were killed after 15 days without DBP administration. The levels of T and glucocorticoid (GC) in serum were determined by radioimmunoassay. The expression levels of 11 beta-dedroxysteriod dehydrogenase (11 beta-HSD) mRNA and steroidogenesis acute regulatory protein (StAR) mRNA were determined by RT-PCR. The protein expression level of glucocorticoid receptor (GR) was investigated by Western blotting. During exposure period, in 1.00 and 2.00 g/kg DBP groups, the levels of T were (0.260 +/- 0.218) ng/ml and (0.260 +/- 0.342) ng/ml, the levels of GC were (13.470 +/- 5.661) ng/ml and (13.740 +/- 3.977) ng/ml, the levels of T and GC in control group were (1.045 +/- 1.222) ng/ml and (9.224 +/- 3.496) ng/ml. There were statistic differences between 1.00 and 2.00 g/kg DBP groups and control group (t(T) values were -2.295 and -2.295, t(GC) values were 2.159 and 2.296, respectively, P < 0.05). The expression level of StAR mRNA was significantly down-regulated in 1.00 and 2.00 g/kg DBP groups, while StAR/beta-Actin values were 0.657 +/- 0.060 and 0.407 +/- 0.033, and compared to control group (0.871 +/- 0.081), there was statistic difference (t values were -3.707 and -8.037, P < 0.05). In 1.00 and 2.00 g/kg DBP groups, the expression of 11 beta-HSD mRNA and the expression of GR protein were increased in DBP dose-dependent manner, while 11 beta-HSD/beta-Actin values were 0.538 +/- 0.138 and 0.988 +/- 0.133, and GR/beta-Actin were 0.785 +/- 0.106 and 0.956 +/- 0.076, respectively. There were statistic difference, as compared to the controls (0.285 +/- 0.106 and 0.275 +/- 0.035) (t(11 beta-HSD/beta-Actin) values were 2.829 and 7.860, t(GR/beta-Actin) values were 8.064 and 10.77, respectively, P < 0.05).Linear correlation and regression revealed that there were positive correlation between DBP dose and the expression levels of 11 beta-HSD mRNA and GR protein, with r values of 0.766 and 0.790, respectively. In post-exposure period, there were no statistic differences of all above index among DBP groups and control group. DBP might inhibit T production in rats through GR mediation.

The aim of our study was to investigate the link between MTHFR gene C677T polymorphism and DNMTs levels in patients with Subclinical Hypothyroidism (SCH). In this study 19 adult patients with subclinical hypothyroidism and 19 healthy controls (mean age 31±5.5 and 33±5.1 years respectively) were recruited. All patients were diagnosed based on serum levels of TSH, FT4, anti-TG and anti-TPO antibodies. Written informed consents were obtained from all study subjects. Genomic DNA was extracted using Quick-DNA Universal Kit (Zymo Research, USA). The MTHFR C677T polymorphism was genotyped by PCR-RFLP method. Levels of DNMT1 and 3a were measured in nuclear extracts of PBMC using DNMTs assay kits (Abcam). Our data indicates that the frequency of genotypes and alleles were different among the patient and the control group. There is a significant increase in CC genotype distribution in the control group when compared to the SCH patient group, while the CT as well as TT genotype distribution were not increased significantly in SCH group versus control group. However the C allele is significantly prevalent in the control group compared to the SCH group, while T allele is prevalent in patients compared to the control group with a statically significant difference. In addition, individuals with TT and CT genotypes and hypothyroidism showed elevated amount of DNMT3a in nuclear extracts of PBMC compared with controls, while no significant difference in DNMT1 levels was observed. This study indicates the MTHFR C677T variant may contribute in alteration of epigenetic regulation such as DNA methylation mediated by DNA methyltransferases in patients with subclinical hypothyroidism and also, carriers of the T allele might have an increasing risk of developing SCH.

Recent years have seen an increase in the use of dexmedetomidine in pediatric patients presenting for surgical procedures. However, only a limited number of studies have evaluated its effects on the QT interval in this patient group. To address this lack of knowledge, we have evaluated the effects of dexmedetomidine on the QT interval in children receiving sevoflurane anesthesia. This study was a prospective case-control study in which pediatric patients presenting for anesthetic care were divided into two groups--the dexmedetomidine (D) and control (C) groups. Three electrocardiograms (ECGs) were obtained on each patient, including a baseline ECG (T1) prior to anesthetic induction and an ECG after the induction of anesthesia with sevoflurane (T2). In group D, the third ECG was obtained 2 min after the administration of dexmedetomidine, which in turn was started immediately after the T2 ECG reading (T3D); in group C, it was obtained 2 min after the T2 reading (T3C). Statistical analysis was performed using analysis of variance to compare the QT intervals at the three time points outlined above. A total of 50 patients were recruited to the study, ranging in age from 1 to 16 [mean 7.9 ± 4.1 (SD) years]. There were 25 patients in group C and 25 in group D. There were no statistical differences in the demographics between the 2 groups. In group C, the QTc was noted to increase progressively with the administration of sevoflurane (T3C vs. T1; P = 0.006). In group D, following the administration of dexmedetomidine, there was a significant decrease in the QTc relative to the post-induction value [436 ± 25 (T2) vs. 418 ± 17 ms (T3D); P < 0.01]. A progressive lengthening of the QTc interval following the administration of sevoflurane was observed in the control group. In the dexmedetomidine group, there was a significant shortening of the QTc interval following the administration of dexmedetomidine compared to the length of the post-induction QTc interval and when compared to the control group.

To investigate the clinical response of gastro-esophageal reflux disease (GERD) symptoms to exclusion diets based on food intolerance tests. A double blind, randomized, controlled pilot trial was performed in 38 GERD patients partially or completely non-responders to proton pump inhibitors (PPI) treatment. Fasting blood samples from each patients were obtained; leukocytotoxic test was performed by incubating the blood with a panel of 60 food items to be tested. The reaction of leukocytes (rounding, vacuolization, lack of movement, flattening, fragmentation or disintegration of cell wall) was then evaluated by optical microscopy and rated as follows: level 0 = negative, level 1 = slightly positive, level 2 = moderately positive, and level 3 = highly positive. A "true" diet excluding food items inducing moderate-severe reactions, and a "control" diet including them was developed for each patient. Then, twenty patients received the "true" diet and 18 the "control" diet; after one month (T1) symptoms severity was scored by the GERD impact scale (GIS). Hence, patients in the "control" group were switched to the "true" diet, and symptom severity was re-assessed after three months (T2). At baseline (T0) the mean GIS global score was 6.68 (range: 5-12) with no difference between "true" and control group (6.6 ± 1.19 vs 6.7 ± 1.7). All patients reacted moderately/severely to at least 1 food (range: 5-19), with a significantly greater number of food substances inducing reaction in controls compared with the "true" diet group (11.6 vs 7.0, P < 0.001). Food items more frequently involved were milk, lettuce, brewer's yeast, pork, coffee, rice, sole asparagus, and tuna, followed by eggs, tomato, grain, shrimps, and chemical yeast. At T1 both groups displayed a reduction of GIS score ("true" group 3.3 ± 1.7, -50%, P = 0.001; control group 4.9 ± 2.8, -26.9%, P = 0.02), although the GIS score was significantly lower in "true" vs "control" group (P = 0.04). At T2, after the diet switch, the "control" group showed a further reduction in GIS score (2.7 ± 1.9, -44.9%, P = 0.01), while the "true" group did not (2.6 ± 1.8, -21.3%, P = 0.19), so that the GIS scores didn't differ between the two groups. Our results suggest that food intolerance may play a role in GERD symptoms development, and leucocytotoxic test-based exclusion diets may be a possible therapeutic approach when PPI are not effective or indicated.

This study highlighted the pro-oxidative functions of α-tocopherol (αT) on the heart antioxidant system and tissue histopathology of oxidized sunflower oil (OSO)-exposed rats.Four groups of male Wistar rats were fed with different diets: 1) control diet containing FSO (fresh sunflower oil); 2) diet containing 5 % OSO; 3) diet containing 5 % OSO, supplemented with 600 mg αT kg-1; and 4) diet containing 5 % OSO, supplemented with 1200 mg αT kg-1. The hearts were then isolated, and the antioxidant enzymatic activities were assessed. Body weight and catalase (CAT), glutathione peroxidase (GPx) activities significantly decreased in groups fed with OSO, while the lipid peroxidation (LPO) level significantly increased. Administration of OSO with αT (600 mg · kg-1) returned the body weight values and LPO levels to similar values as the control group. The CAT and GPx activities increased but remained significantly lower compared to the control group. In the OSO group with αT (1200 mg · kg-1), the CAT and GPx activities also decreased, while LPO significantly increased. Heart tissue sections obtained from the groups revealed the presence of large areas of necrosis. This study suggested that OSO induced oxidative stress and that administration of a moderate dose of αT restored the antioxidant balance, but that high levels of αT supplementation result in a pro-oxidant effect.

This study investigated a theoretically challenging dissociation between good production and poor perception of tones among neurologically unimpaired native speakers of Cantonese. The dissociation is referred to as the near-merger phenomenon in sociolinguistic studies of sound change. In a passive oddball paradigm, lexical and nonlexical syllables of the T1/T6 and T4/T6 contrasts were presented to elicit the mismatch negativity (MMN) and P3a from two groups of participants, those who could produce and distinguish all tones in the language (Control) and those who could produce all tones but specifically failed to distinguish between T4 and T6 in perception (Dissociation). The presence of MMN to T1/T6 and null response to T4/T6 of lexical syllables in the dissociation group confirmed the near-merger phenomenon. The observation that the control participants exhibited a statistically reliable MMN to lexical syllables of T1/T6, weaker responses to nonlexical syllables of T1/T6 and lexical syllables of T4/T6, and finally null response to nonlexical syllables of T4/T6, suggests the involvement of top-down processing in speech perception. Furthermore, the stronger P3a response of the control group, compared with the dissociation group in the same experimental conditions, may be taken to indicate higher cognitive capability in attention switching, auditory attention or memory in the control participants. This cognitive difference, together with our speculation that constant top-down predictions without complete bottom-up analysis of acoustic signals in speech recognition may reduce one’s sensitivity to small acoustic contrasts, account for the occurrence of dissociation in some individuals but not others.

To explore the effects of obstructive sleep apnea syndrome (OSAS) on children's growth by the study of identical twins. Seventeen cases of nonobese children with OSAS were included in this study. The control group was their identical twin sibling, who had no signs of OSAS. Data including height, weight, and serum insulin-like growth factor 1 levels were analyzed before tonsillectomy and adenoidectomy (T&A) and at 3, 6, and 12 months after surgery. The mean apnea hyponea index was 3.9 times/hour in patients with OSAS and became normal after surgery. Minimum oxygen saturation gradually increased after T&A. The height and weight of the OSAS group before T&A was lower than the control group. During the follow-up period, height and weight increased but were lower than the control group. Serum insulin-like growth factor 1 levels in the OSAS group before T&A were lower than the control group. The level was significantly increased 3 months after T&A. OSAS impairs growth and development. Significant growth recovery occurs after T&A, and early surgical intervention is an important factor for improvement in growth. Copyright © 2015.

The probiotic effects of seven newly isolated gut bacteria, from the indegenous honey bees of Saudi Arabia were investigated. In vivo bioassays were used to investigate the effects of each gut bacterium namely, Fructobacillus fructosus (T1), Proteus mirabilis (T2), Bacillus licheniformis (T3), Lactobacillus kunkeei (T4), Bacillus subtilis (T5), Enterobacter kobei (T6), and Morganella morganii (T7) on mortality percentage of honey bee larvae infected with P. larvae spores along with negative control (normal diet) and positive control (normal diet spiked with P. larvae spores). Addition of gut bacteria to the normal diet significantly reduced the mortality percentage of the treated groups. Mortality percentage in all treated groups ranged from 56.67% up to 86.67%. T6 treated group exhibited the highest mortality (86.67%), whereas T4 group showed the lowest mortality (56.67%). Among the seven gut bacterial treatments, T4 and T3 decreased the mortality 56.67% and 66.67%, respectively, whereas, for T2, T6, and T7 the mortality percentage was equal to that of the positive control (86.67%). Mortality percentages in infected larval groups treated with T1, and T5 were 78.33% and 73.33% respectively. Most of the mortality occurred in the treated larvae during days 2 and 3. Treatments T3 and T4 treatments showed positive effects and reduced mortality.

Objective To evaluate the impact of patent ductus arteriosus (PDA) on the pulse phase difference (PPD) between the left foot (postductal region) and the right hand (preductal region). Materials and Methods PPD was determined from arterial photoplethysmography signals (pulse waves) measured by infrared sensors routinely used for pulse oximetry in 56 premature infants less than 32 weeks gestation. Only infants with significant PDA (sPDA) diagnosed by echocardiography were treated with ibuprofen (for 3 days). Patients were classified according to whether or not they responded (Success/Failure) to this treatment. The Control group was composed of infants in whom ductus had already closed spontaneously at the time of the first echocardiography. The 3 groups were compared in terms of PPD at the beginning (T1) and at the end (T2) of the study. For patients in the Failure (n = 17) and Success groups (n = 18), T1 corresponded to the first day of treatment and T2 to the day after completion of the course of ibuprofen. In the Control group (n = 21), T1 corresponded to 1 to 3 days of life (DOL), and T2 to 4–6 DOL. Results Compared to the Control group, PPD was higher in the Failure (at T1 and T2) and Success (at T1) groups characterized by sPDA. After ibuprofen therapy, PPD in the Success group decreased to about the level observed in the Control group. The area under the ROC curve of PPD for the diagnosis of sPDA was 0.98 (95% CI 0.96–1); for an optimal cut-off of PPD ≥1.65 deg/cm, the sensitivity was 94.2% and the specificity was 98.3%. Conclusion In this study, PPD was correlated with ductus arteriosus status evaluated by echocardiography, indicating involvement of the ductal shunt in the mechanism of redistribution in systemic vascular territories. PPD can be considered for the diagnosis of hemodynamically significant PDA. PMID:24892695

To evaluate the effects of fixed orthodontic treatment with steel-ligated conventional brackets and self-ligating brackets on halitosis and periodontal health. Sixty patients, at the permanent dentition stage aged 12 to 18 years, who had Angle Class I malocclusion with mild-to-moderate crowding were randomly selected. Inclusion criteria were nonsmokers, without systematic disease, and no use of antibiotics and oral mouth rinses during the 2-month period before the study. The patients were subdivided into three groups randomly: the group treated with conventional brackets (group 1, n  =  20) ligated with steel ligature wires, the group treated with self-ligating brackets (group 2, n  =  20), and the control group (group 3, n  =  20). The periodontal records were obtained 1 week before bonding (T1), immediately before bonding (T2), 1 week after bonding (T3), 4 weeks after bonding (T4), and 8 weeks after bonding (T5). Measurements of the control group were repeated within the same periods. The volatile sulfur components determining halitosis were measured with the Halimeter at T2, T3, T4, and T5. A two-way repeated measures of analysis of variance (ANOVA) was used to compare the groups statistically. No statistically significant group × time interactions were found for plaque index, gingival index, pocket depth, bleeding on probing, and halitosis, which means three independent groups change like each other by time. The risk of tongue coating index (TCI) being 2 was 10.2 times higher at T1 than at T5 (P < .001). Therefore, the probability of higher TCI was decreased by time in all groups. The self-ligating brackets do not have an advantage over conventional brackets with respect to periodontal status and halitosis.

The study aimed to assess the effects of diabetes-related risk factors, especially severe hypoglycaemia,on the academic skills of children with early-onset type 1 diabetes mellitus (T1DM). The study comprised 63 children with T1DM (31 females, 32 males; mean age 9 y 11 mo,SD 4 mo) and 92 comparison children without diabetes (40 females, 52 males;mean age 9 y 9 mo,SD 3 mo). Children were included if T1DM had been diagnosed before the age of 5 years and if they were aged between 9 and 10 years at the time of study. Children were not included if their native language was not Finnish and if they had a diagnosed neurological disorder that affected their cognitive development. Among the T1DM group, 37 had and 26 had not experienced severe hypoglycaemia and 26 had avoided severe hypoglycaemia. Severe hypoglycaemia, diabetic ketoacidosis(DKA), and glycaemic control were used as T1DM-related factors. Task performance in reading, spelling, and mathematics was compared among the three groups, and the effects of the T1DM-related factors were analysed with general linear models. The groups with (p<0.001) and without (p=0.001) severe hypoglycaemia demonstrated a poorer performance than the comparison group in spelling, and the group without severe hypoglycaemia showed a poorer performance than the comparison group in mathematics (p=0.003).Severe hypoglycaemia, DKA, and recent glycaemic control were not associated with poorer skills,but poorer first-year glycaemic control was associated with poorer spelling (p=0.013). An early onset of T1DM can increase the risk of learning problems, independently of the history of severe hypoglycaemia or DKA. Poorer glycaemic control after the first year of T1DM is associated with a poorer acquisition of academic skills indicating the effect of the timing of metabolic aberrations on cognitive development.

Web-based, computer-tailored nutrition education interventions can be effective in modifying self-reported dietary behaviors. Traditional computer-tailored programs primarily targeted individual cognitions (knowledge, awareness, attitude, self-efficacy). Tailoring on additional variables such as self-regulation processes and environmental-level factors (the home food environment arrangement and perception of availability and prices of healthy food products in supermarkets) may improve efficacy and effect sizes (ES) of Web-based computer-tailored nutrition education interventions. This study evaluated the short- and medium-term efficacy and educational differences in efficacy of a cognitive and environmental feedback version of a Web-based computer-tailored nutrition education intervention on self-reported fruit, vegetable, high-energy snack, and saturated fat intake compared to generic nutrition information in the total sample and among participants who did not comply with dietary guidelines (the risk groups). A randomized controlled trial was conducted with a basic (tailored intervention targeting individual cognition and self-regulation processes; n=456), plus (basic intervention additionally targeting environmental-level factors; n=459), and control (generic nutrition information; n=434) group. Participants were recruited from the general population and randomly assigned to a study group. Self-reported fruit, vegetable, high-energy snack, and saturated fat intake were assessed at baseline and at 1- (T1) and 4-months (T2) postintervention using online questionnaires. Linear mixed model analyses examined group differences in change over time. Educational differences were examined with group×time×education interaction terms. In the total sample, the basic (T1: ES=-0.30; T2: ES=-0.18) and plus intervention groups (T1: ES=-0.29; T2: ES=-0.27) had larger decreases in high-energy snack intake than the control group. The basic version resulted in a larger decrease in saturated fat intake than the control intervention (T1: ES=-0.19; T2: ES=-0.17). In the risk groups, the basic version caused larger decreases in fat (T1: ES=-0.28; T2: ES=-0.28) and high-energy snack intake (T1: ES=-0.34; T2: ES=-0.20) than the control intervention. The plus version resulted in a larger increase in fruit (T1: ES=0.25; T2: ES=0.37) and a larger decrease in high-energy snack intake (T1: ES=-0.38; T2: ES=-0.32) than the control intervention. For high-energy snack intake, educational differences were found. Stratified analyses showed that the plus version was most effective for high-educated participants. Both intervention versions were more effective in improving some of the self-reported dietary behaviors than generic nutrition information, especially in the risk groups, among both higher- and lower-educated participants. For fruit intake, only the plus version was more effective than providing generic nutrition information. Although feasible, incorporating environmental-level information is time-consuming. Therefore, the basic version may be more feasible for further implementation, although inclusion of feedback on the arrangement of the home food environment and on availability and prices may be considered for fruit and, for high-educated people, for high-energy snack intake.

Background Web-based, computer-tailored nutrition education interventions can be effective in modifying self-reported dietary behaviors.

To evaluate the immediate and sustained effectiveness of the first Jamie's Ministry of Food Program in Australia on individuals' cooking confidence and positive cooking/eating behaviours. A quasi- experimental repeated measures design was used incorporating a wait-list control group. A questionnaire was developed and administered at baseline (T1), immediately post program (T2) and 6 months post completion (T3) for participants allocated to the intervention group, while wait -list controls completed it 10 weeks prior to program commencement (T1) and just before program commencement (T2). The questionnaire measured: participants' confidence to cook, the frequency of cooking from basic ingredients, and consumption of vegetables, vegetables with the main meal, fruit, ready-made meals and takeaway. Analysis used a linear mixed model approach for repeated measures using all available data to determine mean differences within and between groups over time. All adult participants (≥18 years) who registered and subsequently participated in the program in Ipswich, Queensland, between late November 2011- December 2013, were invited to participate. In the intervention group: 694 completed T1, 383 completed T1 and T2 and 214 completed T1, T2 and T3 assessments. In the wait-list group: 237 completed T1 and 149 completed T1 and T2 assessments. Statistically significant increases within the intervention group (P<0.001) and significant group*time interaction effects (P<0.001) were found in all cooking confidence measures between T1 and T2 as well as cooking from basic ingredients, frequency of eating vegetables with the main meal and daily vegetable intake (0.52 serves/day increase). Statistically significant increases at T2 were sustained at 6 months post program in the intervention group. Jamie's Ministry of Food Program, Australia improved individuals' cooking confidence and cooking/eating behaviours contributing to a healthier diet and is a promising community-based strategy to influence diet quality.

Acute hemodynamic responses to electroconvulsive therapy (ECT) may increase the risk of cardiovascular complications in vulnerable patients. The aim of the current study was to assess the effect of small-dose dexmedetomidine on hyperdynamic responses to ECT. Seventy-eight patients were enrolled and randomly allocated to receive either 0.2 μg/kg dexmedetomidine (Dex group, n = 39) or saline (Control group, n = 39) prior to ECT. Heart rate (HR) and mean arterial pressure (MAP) were recorded immediately after the administration of dexmedetomidine (T1), and 0, 1, 3, 5 and 10 min after the electrical stimuli ended (T2, T3, T4, T5 and T6). In addition, the peak HR after ECT, seizure duration, recovery time, and incidence rates of post-ECT adverse effects (agitation, headache and nausea) were also recorded. HR and MAP in the Dex group were significantly lower than those in the Control group from T2 to T5. In addition, peak HR was significantly lower in the Dex group compared with that in the Control group. Seizure length and time to spontaneous breathing, eye opening, and obeying commands in the Dex group were similar to those in the Control group. The incidence rates of post-ECT agitation and headache in the Dex group were significantly lower than that in the Control group. The administration of 0.2 μg/kg dexmedetomidine to patients receiving ECT leads to a significant reduction in HR, MAP, and peak HR responses to ECT without altering seizure duration or delaying recovery. Furthermore, dexmedetomidine effectively reduced the incidence rates of post-ECT adverse effects such as agitation and headache. Copyright © 2017. Published by Elsevier Taiwan LLC.

Medical students have higher rates of depression and psychologic distress than the general population, which may negatively impact academic performance and professional conduct. This study assessed whether 10-20 min of daily mindfulness meditation for 30 days, using a mobile phone application, could decrease perceived stress and improve well-being for medical students. Eighty-eight medical students were stratified by class year and randomized to either intervention or control groups to use the mobile application Headspace, an audio-guided mindfulness meditation program, for 30 days. All participants completed the Perceived Stress Scale (PSS), Five-Facet Mindfulness Questionnaire (FFMQ), and General Well-Being Schedule (GWBS) at baseline (T1), 30 days (T2), and 60 days (T3). Repeated measures analysis of variance (rANOVA) was conducted for intervention versus control groups across T1, T2, and T3 to examine differences in stress, mindfulness, and well-being. There was a significant interaction between time and treatment group for perceived stress and well-being. Perceived stress significantly decreased for the intervention group from T1 to T3 (F[2,142] = 3.98, p < 0.05). General well-being significantly increased for the intervention group compared to the control group from T1 to T2, and the increase was sustained through T3 (F[2,144] = 3.36, p < 0.05). These results highlight that a mobile audio-guided mindfulness meditation program is an effective means to decrease perceived stress in medical students, which may have implications on patient care. Integrating mindfulness training into medical school curricula for management of school- and work-related stress may lead to fewer negative physician outcomes (e.g., burnout, anxiety, and depression) and improved physician and patient outcomes. This has implications for a broad group of therapists and healthcare providers, ultimately improving quality of healing and patient care.

This experiment investigated the effect of dietary chromium (Cr as picolinate) on physical and biochemical characteristics of semen and carcass traits of adult male turkey. Seventy-two (72) male turkeys (16 weeks old) were randomly distributed into four dietary treatment groups (4×3×6) for a period of 24 weeks. Three experimental diets were supplemented with 250, 500 and 750μg Cr/kg (T2, T3 and T4 respectively) in basal diet (T1 considered as control). Semen physical characteristics viz. sperm concentration, progressive motility, live and dead count of spermatozoa and fertility differed significantly (P<0.05). Sperm concentration, progressive motility and fertility were higher and dead count was lower in T4 (750μg) group than control (T1) or other dietary treatments (T2 or T3) group. Semen biochemical parameters like creatinine, acid phosphatase (ACP) and alkaline phosphatase (ALP) concentration did not differ significantly among the dietary treatment groups, whereas, total protein, glucose, malondialdehyde (MAD) and cholesterol concentration differed significantly (P<0.05) amongst the treatment groups. Protein and MAD were higher while glucose and cholesterol concentrations were lower in T3 and T4 group than control or T1 group. The shrinkage loss, eviscerated yield, relative weight (as percent of body weight) of breast, thigh and liver improved on supplementation of Cr leading to significantly higher in T4 group in comparison to control. From this study, it could be concluded that supplementation of chromium as chromium picolinate, at 750μg/kg level in diet was beneficial for improving physical characteristics of semen, carcass yield and breast yield of adult male turkeys. However, Cr levels of 500 or 750μg/kg in diet were beneficial for semen biochemical parameters of adult male turkeys. Copyright © 2014 Elsevier B.V. All rights reserved.

The aim of this study was to explore the cytomorphometric and morphological effects of Trichomonas vaginalis in exfoliated epithelial cells. Ninety-six Pap-stained cervical smears were divided into a study group and two control groups as follows: T. vaginalis cases, a first control group with inflammation, and a second control group without inflammation. Micronucleated, binucleated, karyorrhectic, karyolytic, and karyopyknotic cells and cells with perinuclear halos per 1,000 epithelial cells were counted. Nuclear and cellular areas were evaluated in 70 clearly defined cells in each smear using image analysis. The frequencies of morphological parameters in the T. vaginalis cases were higher than the values of the two control groups, and the difference among groups was found to be significant (p < 0.05). The nuclear and cytoplasmic areas of epithelial cells were diminished in patients with trichomoniasis. The mean nucleus/cytoplasm ratio in T. vaginalis patients was higher than the value in the control groups, and the difference between the study group and control group 1 was significant. However, there was no statistically significant increase between the study group and control group 2. T. vaginalis exhibited significant changes in the cellular size and nuclear structure of the cells. The rising frequency of micronuclei, nuclear abnormalities, and changing nucleus/cytoplasm ratio may reflect genotoxic damage in trichomoniasis. © 2015 S. Karger AG, Basel.

Pregestational diabetes mellitus (type 1 and type 2) affects about 1% of the obstetric population. In diabetes, persistent hyperglycemia can be a source of DNA damage via overproduction of reactive oxygen species (ROS). Using the cytokinesis-block micronucleus (CBMN) test, we measured the frequencies of micronuclei (MN) per 1000 binucleated (BN) cells in pregnant women (mothers) with type 1 diabetes mellitus (T1DM) and in their newborns. Peripheral blood lymphocytes were collected from 17 pregnant women with T1DM and cord-blood lymphocytes from their 17 newborns. The control group included 40 pregnant women (mothers) without diabetes mellitus (DM) and their 40 newborns. In the group of pregnant women with T1DM, the mean number of MN per 1000 BN cells was 2.35 (±1.07), significantly (p<0.001) higher than in the control group of pregnant women (0.86±0.90). The frequency value in the group of newborns of T1DM mothers was 1.42 (±0.60), significantly (p<0.05) higher than in the corresponding control group (0.67±0.79). The value in the group of mothers with T1DM was significantly (p<0.05) higher than in their newborns. Comparing mothers without DM with their newborns, no significant frequency differences were observed. No significant correlations were observed between MN frequencies in mothers with T1DM and either the frequencies in their newborns, the duration of diabetes, or HbA1C levels. Our results indicate that T1DM is accompanied by increased frequencies of MN in pregnant women and their newborns. Copyright © 2014 Elsevier B.V. All rights reserved.

To investigate the role of brain-derived neurotrophic factor (BDNF) in pain facilitation and spinal mechanisms in the rat model of bone cancer pain. The bone cancer pain model was developed by inoculated Walker 256 mammary gland carcinoma cells into the tibia medullary cavity. Sixty SD female rats were divided into 5 groups (n = 12 each) randomly; group I: control group (sham operation); group II: model group; group III: control group + anti-BDNF intrathecal (i.t.); group IV: model group + control IgG i.t.; group V: model group + anti-BDNF i.t.. Anti-BDNF or control IgG was injected i.t. during 7 to 9th day. Von-Frey threshold was measured one day before operation and every 2 days after operation. On the 9th day after threshold tested, rats were sacrificed after i.t. injection of either anti-BDNF or control IgG, the lumbar 4-6 spinal cord was removed. The expression of the spinal BDNF and the phosphorylation of extracellular signal-regulated protein kinase 1/2 (p-ERK1/2) were detected by immunohistochemistry assay and Western-Blot. Co-expression pattern of BDNF and p-ERK1/2 were determined by double-labeling immunofluorescence. We demonstrated the coexistence of BDNF and p-ERK1/2 in the spinal cord of rats. From the 7 to 9th day after operation, von-Frey threshold in groups II and IV was significantly lower than that in group I and group V (P < 0.01), group V was remarkly higher than that in group IV (P < 0.01). The spinal BDNF and p-ERK1/2 expression in group II or IV were significantly increased compared with that in group I or V (P < 0.01), intrathecal anti-BDNF was significantly suppressed BDNF and p-ERK1/2 expression (P < 0.01). BDNF and p-ERK1/2 was coexistence in the spinal cord of rats, and it maybe involved in the bone cancer pain.

Nonspecific ST-segment and T-wave (ST-T) changes represent one of the most prevalent electrocardiographic abnormalities in hypertensive patients. However, a limited number of studies have investigated the association between nonspecific ST-T changes and unsatisfactory blood pressure (BP) control in adults with hypertension.The study population comprised 15,038 hypertensive patients, who were selected from 20,702 participants in the China Stroke Primary Prevention Trial. The subjects were examined with electrocardiogram test at the initial visit in order to monitor baseline heart activity. According to the results of the electrocardiogram (defined by Minnesota coding), the subjects were divided into 2 groups: ST-T abnormal and ST-T normal. Unsatisfactory BP control was defined as systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg following antihypertensive treatment during the 4.5-year follow-up period. Multivariate analysis was used to analyze the association between nonspecific ST-T abnormalities and unsatisfactory BP control.Nonspecific ST-T changes were common in hypertensive adults (approximately 8.5% in the study), and more prevalent in women (10.3%) and diabetic patients (13.9%). The unsatisfactory BP control rate was high in the total population (47.0%), notably in the ST-T abnormal group (55.5%). The nonspecific ST-T abnormal group exhibited a significantly greater rate of unsatisfactory BP control (odds ratio [OR] 1.20, 95% confidence interval [CI] [1.06, 1.36], P = 0.005]), independent of traditional risk factors, as demonstrated by multivariate regression analysis. Notable differences were further observed in male subjects (OR 1.51, 95% CI [1.17, 1.94], P = 0.002) and in patients with comorbid diabetes (OR 1.47, 95% CI [1.04, 2.07], P = 0.029).Greater rates of unsatisfactory BP control in hypertensive patients with electrocardiographic nonspecific ST-T abnormalities were observed, notably in the subcategories of the male subjects and the diabetic patients.

This study examined a possible association of the insulin (INS) gene with type 1 diabetes (T1D) in patients and controls from four ethnic groups in Israel. We analyzed the distribution of -23HphI single nucleotide polymorphism (SNP) T/A alleles that correspond to INS variable number of tandem repeat short class I alleles (26-63 repeats) and class III alleles (141-209 repeats), respectively. The -23HphI T/T genotype was found to be positively associated with T1D in three Jewish groups (Yemenites: 93.9% patients vs 68.8% controls, P = 0.0002; Ashkenazi: 80.6% vs 50.8%, P < 10(-4); Ethiopians: 75% vs 40.5%, P = 0.002). The Yemenite healthy controls have the highest frequency of T allele from all Jewish groups studied (83.5% vs 68.8% in Ashkenazi and 64.3% in Ethiopians). The high frequency of a susceptibility allele in the Yemenites is in line with the high incidence of T1D in this population. No association was observed between T1D and the INS gene in Israeli Arabs studied (70.6% vs 66.7%). Variable incidence of T1D among different ethnicities in Israel is largely attributed to heterogeneous genetics. Human leukocyte antigen (HLA) results of our previous studies describing the susceptibility and protective haplotypes were used for combined analysis to determine possible interaction between the HLA and INS loci. Only in the Ashkenazi group such interaction was presented with statistical significance.

To evaluate renal outcomes and survival in youth with type 2 diabetes (T2DM) versus type 1 diabetes (T1DM) versus nondiabetic control subjects. In total, 342 prevalent youth (aged 1-18 years) with T2DM, 1,011 youth with T1DM, and 1,710 control subjects identified from 1986 to 2007 were anonymously linked to health care records housed at the Manitoba Centre for Health Policy to assess long-term outcomes using ICD codes. Youth with T2DM were found to have a fourfold increased risk of renal failure versus youth with T1DM. Risk factors associated with renal failure were renin angiotensin aldosterone system inhibitor use and albuminuria in adolescence. Compared with control subjects (age, sex, and postal code matched), youth with T2DM had a 23-fold increased risk of renal failure and a 39-fold increased risk of dialysis. Kaplan-Meier survival at 10 years was 91.4% in the type 2 diabetic group versus 99.5% in the type 1 diabetic group (P < 0.0001). Renal survival was 100% at 10 years in both groups. It decreased to 92.0% at 15 years and 55.0% at 20 years in the type 2 diabetic group but remained stable in the type 1 diabetic group (P < 0.0001). Youth with T2DM are at high risk of adverse renal outcomes and death. Albuminuria and angiotensin aldosterone system inhibitor use, which may be a marker of severity of disease, are associated with poor outcomes in early adulthood.

The aim of this study was to evaluate the efficacy of animal-assisted therapy (AAT) in elderly patients affected by Alzheimer's disease based on the formal reality orientation therapy (ROT) protocol. Our study was carried out at an Alzheimer's centre for 6 months. A homogeneous sample (age, Mini-Mental State Examination (MMSE), 15-item Geriatric Depression Scale (GDS)) of 50 patients was selected at random and successively. Patients were divided into three groups: (i) 20 patients received a course of AAT (AAT group) based on the ROT protocol; (ii) 20 patients were engaged exclusively in activities based on the ROT group; and (iii) 10 patients (control group) participated in no stimulations. MMSE and GDS were administered at time 0 (T0 ) and time 1 (T1 ) to all three groups. Differences within groups between T0 and T1 for GDS and MMSE scores were analyzed by Student's t-test. Differences between group means were analyzed using an anova test with the Bonferroni-Dunn test for post-hoc comparisons. Both the AAT group and ROT group had improved GDS scores and showed a slight improvement in terms of mood. On the GDS, the AAT group improved from 11.5 (T0 ) to 9.5 (T1 ), and the ROT group improved from 11.6 (T0 ) to 10.5 (T1 ). At the same time, a slight improvement in cognitive function, as measured by the MMSE, was observed. In the AAT group, mean MMSE was 20.2 at T0 and 21.5 at T1 , and in the ROT group, it was 19.9 at T0 and 20.0 at T1 . In the control group, the average values of both the GDS and MMSE remained unchanged. The Bonferroni-Dunn results showed statistically significant differences between groups, particularly between the AAT group and the other two (P < 0.001). Pet therapy interventions based on the formal ROT protocol were effective and, compared to the ROT, provided encouraging and statistically significant results. © 2015 The Authors.

Forskolin, a direct activator of adenylate cyclase, can relax airway smooth muscle, similar to other agents that increase intracellular cyclic adenine monophosphate. However, the potential usefulness of forskolin in treating bronchospasm is limited by its poor water solubility. Colforsin daropate is a novel and potent water-soluble forskolin derivative. No clinical data have been published on the bronchorelaxant effects of this drug. The aim of this study was to investigate whether intravenous colforsin daropate prevents thiamylal-fentanyl-induced bronchoconstriction. Double-blind, prospective, placebo-controlled randomized study. University teaching hospital. Thirty-six patients were allocated randomly to two groups: the control group (n = 18) and colforsin daropate group (n = 18). Intravenous administration of colforsin daropate or placebo (normal saline). Anesthesia was induced with thiamylal 5 mg/kg and vecuronium 0.3 mg/kg. A 15 mg x kg(-1) x hr(-1) continuous infusion of thiamylal followed anesthetic induction. Controlled ventilation was maintained, delivering 50% nitrous oxide in oxygen. Twenty minutes after the induction of anesthesia, the control group patients started to receive 7.5 mL/hr continuous infusion of normal saline, and the colforsin daropate group patients started to receive 0.75 microg x kg(-1) x min(-1) (7.5 mL/hr) continuous infusion of colforsin daropate for 60 min. After that, both groups received fentanyl 5 microg/kg. Systolic and diastolic arterial pressure, heart rate, mean airway resistance (Rawm), expiratory airway resistance (Rawe), and dynamic lung compliance (Cdyn) were measured at the baseline, just before the administration of fentanyl (T30), at three consecutive 6-min intervals after fentanyl injection (T36, T42, and T48) and 30 min after fentanyl injection (T60). At baseline, both groups had comparable Rawm, Rawe, and Cdyn values. In the control group, Rawm increased significantly at T36-60 compared with the baseline, Rawe increased significantly at T36-48 compared with the baseline, and Cdyn decreased significantly at T36-60 compared with the baseline. In the colforsin daropate group, there were no changes in Rawm, Rawe or Cdyn at T36-60. These observations suggest that intravenous colforsin daropate has a bronchodilator effect in humans.

Plasma levels of lipoprotein(a) [Lp(a)], tissue plasminogen activator (tPA) and plasminogen activator inhibitor type 1 (PAI-1) were assessed in addition to anthropometry and levels of glucose, total cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and apo A1 and B in 73 patients (36 men and 37 women) with primary hyperlipidaemia (group NDHL) in Kuwait. Lp(a) levels (212 mg L-1, 8-600 mg L-1, median and range) were similar to those obtained in a matched group of 32 non-insulin-dependent diabetes mellitus (NIDDM) patients with hyperlipidaemia (218 mg L-1, 50-610 mg L-1) and slightly higher, although not significantly so (P = 0.06), than levels seen in 68 healthy normolipidaemic control subjects (182 mg L-1, 70-488 mg L-1). tPA levels (8.4 ng mL-1, 3.8-18.4 ng mL-1, median and range) in group NDHL were lower than in the diabetic group (11.4 ng mL-1, 5.2-14.2 ng mL-1) but higher than in the healthy control subjects (7.4 ng mL-1, 2.8-12.6 ng mL-1). PAI-1 levels in group NDHL (40.4 ng mL-1, 8.6-55 ng mL-1, median and range) were higher than in the control subjects (32.5 ng mL-1, 14.6-46.4 ng mL-1) but lower than in diabetic patients (43.8 ng mL-1, 15.6-55 ng mL-1). Hyperlipidaemia phenotype (hypercholesterolaemia or hypertriglyceridaemia) did not influence tPA and PAI-1 levels, but Lp(a) levels were significantly lower with hypertriglyceridaemia. Gender, cigarette smoking and racial origin (Kuwaitis, other Arabs or South Asians) did not affect Lp(a), tPA and PAI-1 levels, but tPA levels were higher in postmenopausal subjects. Low-density lipoprotein (LDL) levels (whether in total cholesterol or as apo B) correlated significantly (P < 0.05) with Lp(a) levels. tPA levels were correlated with age and the plasma levels of glucose and uric acid (P < 0.05); this correlation with glucose may explain the high levels associated with diabetes, whereas the age association might account not only for the differences observed between group NDHL and the younger control group but also for the higher levels in the postmenopausal women. PAI-1 levels correlated with tPA and triglyceride (TG) levels in the groups of subjects (normo- and hyperlipidaemic). In the normolipidaemic control group, the significant associations of tPA and PAI-1 were with body mass, expressed as the body mass index or the waist-hip ratio. These results suggest that different factors influence the plasma levels of the prothrombotic factors Lp(a), tPA and PAI-1 in healthy control subjects and in patients with hyperlipidaemia. In the latter, hyperlipidaemia phenotype, age, glycaemic status and uric acid levels are important determinants of the levels of these prothrombotic variables, whereas in the healthy, young control population, body mass was the single important association with tPA and PAI-1.

To investigate the protective effect of the active form of vitamin D3, 1,25-(OH)2D3, on macrovasculopathy in rats with type 2 diabetes mellitus (T2DM), 8-week-old male Sprague-Dawley rats were randomly divided into control group, T2DM group, and treatment group. The T2DM model was established after 6 weeks by administering an intraperitoneal injection of streptozotocin (30 mg/kg). 1,25-(OH)2D3 was administered by gavage to rats in the treatment group, and an equal volume of peanut oil was administered to rats in the T2DM group. Fasting plasma glucose (FPG), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C) cholesterols were measured in all rats. The morphology of the thoracic aorta was examined, and the expression of tumor necrosis factor alpha (TNF-α), endothelin (ET), endothelial nitric oxide synthase (eNOS), CD54, and CD106 in the thoracic aorta was determined by immunohistochemistry. The expression of FPG, TG, TC, and LDL-C in rats from the T2DM and treatment groups was significantly elevated compared with rats from the control group (P < 0.05). Compared with that in control group, the expression of TNF-α, ET, eNOS, and CD106 was significantly upregulated in the T2DM group and the treatment group, while the expression of CD54 was increased only in the T2DM group (P < 0.05). Moreover, the levels of TNF-α, CD54, and CD106 in rats from the treatment group were lower than those in the T2DM group (P < 0.05). These data suggest that 1,25-(OH)2D3 may protect the macrovessels from injury in T2DM rats by inhibiting the expression of TNF-α, CD54, and CD106.

An angiogenesis factor, angiopoietin-1 (Ang1), is associated with the blood-brain barrier (BBB) disruption after focal cerebral ischemia. However, whether hemorrhagic transformation and cerebral edema after tissue plasminogen activator (tPA) treatment are related to the decrease in Ang1 expression in the BBB remains unknown. We hypothesized that administering Ang1 might attenuate hemorrhagic transformation and cerebral edema after tPA treatment by stabilizing blood vessels and inhibiting hyperpermeability. Sprague-Dawley rats subjected to thromboembolic focal cerebral ischemia were assigned to a permanent ischemia group (permanent middle cerebral artery occlusion; PMCAO) and groups treated with tPA at 1 h or 4 h after ischemia. Endogenous Ang1 expression was observed in pericytes, astrocytes, and neuronal cells. Western blot analyses revealed that Ang1 expression levels on the ischemic side of the cerebral cortex were decreased in the tPA-1h, tPA-4h, and PMCAO groups as compared to those in the control group (P = 0.014, 0.003, and 0.014, respectively). Ang1-positive vessel densities in the tPA-4h and PMCAO groups were less than that in the control group (p = 0.002 and <0.001, respectively) as well as that in the tPA-1h group (p = 0.047 and 0.005, respectively). These results suggest that Ang1-positive vessel density was maintained when tPA was administered within the therapeutic time window (1 h), while it was decreased when tPA treatment was given after the therapeutic time window (4 h). Administering Ang1 fused with cartilage oligomeric protein (COMP) to supplement this decrease has the potential to suppress hemorrhagic transformation as measured by hemoglobin content in a whole cerebral homogenate (p = 0.007) and cerebral edema due to BBB damage (p = 0.038), as compared to administering COMP protein alone. In conclusion, Ang1 might be a promising target molecule for developing vasoprotective therapies for controlling hemorrhagic transformation and cerebral edema after tPA treatment. PMID:24896569

Type 1 diabetes mellitus (T1DM) and celiac disease (CD) are autoimmune diseases and have similar genetic patterns. T1DM treatment is based on diet, physical activity and insulin therapy, whereas CD depends on dietary changes with restriction of wheat, rye and barley. The aim of the study was to evaluate the quality of life (QoL) of individuals with the association of T1DM and CD, to characterize their nutritional status and to compare it with those with only one disease and healthier controls. Sixty patients controlled by sex, age and body mass index (BMI) were stratified by previous diagnosis in: T1DM and CD (DMCD group); T1DM (DM group); CD (CD group); or healthy participants (HC). The SF-36 questionnaire was applied to assess psychological well being and results were compared with glycemic control and presence of complications related to diabetes, adhesion to gluten-free diet (GFD). Nutritional status and body mass composition were determined by BMI, waist circumference, bioimpedance, general laboratory tests and whole-body densitometry. The time of diagnosis of T1DM was similar between DMCD and DM groups; however, the duration of CD was significantly higher in the CD group compared with DMCD. The SF-36 analysis revealed statistically significant differences between DM and HC groups in two domains: general health (P=0.042) and energy/vitality (P=0.012). QoL was also correlated with compliance to a GFD, and scores were similar in both groups: DMCD and CD. Forty percent of individuals in the CD group had visceral fat area above 100 cm 2 , as opposed to 20% in the other groups. Individuals of DMCD group had similar scores to DM, CD and HC on QoL, as well as on their nutritional status and bone metabolism. Thereby, we should conclude that the association of T1DM and CD did not deteriorate their health status.

To discuss the influence of different ways of low-dose corticosteroids infusion on hemodynamics, changes in blood glucose level and prognosis in patients with refractory septic shock. A prospective single-blind randomized controlled trial was conducted. Refractory septic shock patients admitted to the Department of Critical Care Medicine of Jiangxi Provincial People's Hospital from April 1st, 2013 to October 31st, 2014 were enrolled for the study. The patients were divided into control group and research group by random number table. Besides conventional treatment for septic shock, patients in control group were given 200 mg/d hydrocortisone intravenous infusion lasting for 2 hours, while those of research group were given 8.33 mg/h hydrocortisone per hour with an intravenous pump. Treatment lasted for 5 continuous days for both groups. The changes in heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP) and arterial blood lactic acid in both groups were observed at the time of enroldment and 6 hours, 24 hours, 48 hours, and 5 days after the treatment. With a dynamic blood glucose monitor, mean blood glucose (MBG) level, largest amplitude of glycemic excursions (LAGE), glucose variability (GV), and the ratio of hyperglycaemia time were recorded. The duration of shock, length of intensive care unit (ICU) stay, total length of hospital stay, and 28-day mortality of both groups were recorded. Seventy-nine septic shock patients were assigned to the treatment, with 41 in control group, and 38 in research group. Compared with control group, 6-hour MAP in research group was obviously lowered [mmHg (1 mmHg=0.133 kPa): 66.31±4.38 vs. 68.58±4.86, t=1.062, P=0.033], but there were no significant differences in HR, MAP, CVP, lactic acid clearance and norepinephrine (NE) utilization rates at other time points between two groups. No significant difference in MBG was found between research group and control group (mmol/L: 8.69±2.14 vs. 9.95±3.87, t=1.771, P=0.080), but LAGE, GV, the ratio of hyperglycemia time in research group were significantly lower than those of the control group [LAGE (mmol/L): 17.18±8.97 vs. 22.71±11.80, t=2.331, P=0.022; GV (mmol/L): 2.57±1.05 vs. 3.16±1.37, t=2.136, P=0.036; the ratio of hyperglycemia time: (43.1±11.7)% vs. (49.4±15.3)%, t=2.044, P=0.044]. There was no statistical difference in the following features between research group and control group, such as the duration of shock (days: 3.47±0.98 vs. 3.61±1.07, t=0.605, P=0.547), length of ICU stay (days: 8.74±3.12 vs. 9.97±3.37, t=1.543, P=0.120), total length of hospital stay (days: 18.34±9.27 vs. 19.58±9.83, t=0.576, P=0.566) and 28-day mortality rate (23.68% vs. 26.83%, χ2=0.103, P=0.748). Compared with slow intravenous infusion, a continuous intravenous supplementation of small amount of hydrocortisone to patients with refractory septic shock could stabilize blood glucose levels and maintain metabolic balance efficiently. However, in both groups there was no significant difference in the efficiency in stabilizing hemodynamics, shortening shock duration, reducing ICU or hospital days and decreasing 28-day mortality.

This study evaluated the activity of cardiac and renal antioxidant enzymes [superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), and glutathione reductase (GR)] and whether chronic treatment with tempol, a cell membrane-permeable SOD mimetic, ameliorates the hypertension of hyperthyroidism. Two experiments were performed. In experiment I, the following four groups of male Wistar rats were used: control group and three groups that received thyroxine (T4) at 10, 50, or 75 microg x rat(-1) x day(-1). In experiment II, tempol was orally administered (18 mg x kg(-1) x day(-1)) to control and T4-treated (75 microg x rat(-1) x day(-1)) rats. All treatments were maintained for 6 wk. Body weight, tail systolic blood pressure (BP), and heart rate were measured one time a week, and direct BP and morphological, metabolic, plasma, and renal variables were measured at the end of the experiment. Enzymatic activities were measured in renal cortex and medulla and right and left ventricles. In renal cortex, SOD activity was decreased in the T4-75 group, and there was a dose-related increase in CAT activity and decrease in GPX and GR activities in T4-treated groups. Activity of all antioxidant enzymes was reduced in left ventricle in T4-50 and T4-75 groups and in right ventricle in the T4-75 group. Tempol reduced BP, plasma malondialdehyde, and total urinary excretion of F2 isoprostanes in hypertensive hyperthyroid rats but not in controls. Tempol did not improve cardiac hypertrophy, proteinuria, or creatinine clearance in hyperthyroid rats. In conclusion, the results obtained indicate that the activity of SOD, GPX, and GR in renal and cardiac tissues is decreased in hyperthyroidism and that antioxidant treatment with tempol ameliorates T4-induced hypertension.

The objective of this prospective, double-blind, randomized clinical trial was to compare the effect of 2 dexamethasone dosages on reducing facial swelling after orthognathic surgery through 3-dimensional (3D) photogrammetry. Patients were classified into group 1 (control group) and group 2 (study group), depending on the administered dexamethasone dosage (5 and 15 mg, respectively). Three-dimensional images were recorded at 5 time points: preoperative (T0) and postoperative at 48 ± 6 hours (T1), 1 week (T2), 1 month (T3), and 6 months (T4). A preliminary study was performed on 5 patients, in whom 3D images were captured at 24, 36, 48, and 60 hours postoperatively to record serial changes in facial swelling. Facial swelling at T1, T2, and T3 and the reduction in swelling at T2 and T3 compared with that at the baseline (T4) were calculated. Possible complications, namely, adrenal suppression, wound dehiscence, wound infection, and postoperative nausea and vomiting were evaluated. In total, 68 patients were enrolled, of whom 25 patients in group 1 and 31 patients in group 2 were eligible for final evaluation. No significant differences were found between the 2 groups at any period. On average, the swelling subsided by 86% at 1 month after the orthognathic surgery. Facial swelling peaked approximately 48 hours after the surgery. The incidence of nausea and vomiting did not differ significantly between the groups. The effect of 5 and 15 mg of dexamethasone on facial swelling reduction as well as on nausea and vomiting after orthognathic surgery was not significantly different.

Background Insulin resistance increases during adolescence in those with type 1 diabetes (T1DM), complicating glycemic control and potentially increasing cardiovascular disease (CVD) risk. Metformin, typically used in type 2 diabetes (T2DM), is a possible adjunct therapy in T1DM to help improve glycemic control and insulin sensitivity. Objective We hypothesized that metformin would improve metabolic parameters in adolescents with T1DM. Design, Setting, and Participants This randomized, double-blinded, placebo-controlled trial included 74 pubertal adolescents (ages 13–20 years) with T1DM. Participants were randomized to receive either metformin or placebo for six months. HbA1c, insulin dose, waist circumference, BMI, and blood pressure were measured at baseline, 3 and 6 months, with fasting lipids measured at baseline and 6 months. Results Total daily insulin dose, BMI Z-score and waist circumference significantly decreased at 3 and 6 months compared to baseline within the metformin group, even among normal-weight participants. In placebo group, total insulin dose and systolic blood pressure increased significantly at 3 months and total insulin dose increased significantly at 6 months. No significant change was observed in HbA1c at any time point between metformin and placebo groups or within either group. Conclusions Low-dose metformin likely improves BMI as well as insulin sensitivity in T1DM adolescents, as indicated by a decrease in total daily insulin dose. The decrease in waist circumference indicates that fat distribution is also likely impacted by metformin in T1DM. Further studies with higher metformin doses and more detailed measurements are needed to confirm these results, their underlying mechanisms, and potential impact on CVD in T1DM youth. PMID:24698216

Cistanches Herba (CH) is thought to be a “Yang-invigorating” material in traditional Chinese medicine. We evaluated neuroprotective effects of Cistanches Herba on Alzheimer's disease (AD) patients. Moderate AD participants were divided into 3 groups: Cistanches Herba capsule (CH, n = 10), Donepezil tablet (DON, n = 8), and control group without treatment (n = 6). We assessed efficacy by MMSE and ADAS-cog, and investigated the volume changes of hippocampus by 1.5 T MRI scans. Protein, mRNA levels, and secretions of total-tau (T-tau), tumor necrosis factor-α (TNF-α), and interleukin- (IL) 1β (IL-1β) in cerebrospinal fluid (CSF) were detected by Western blot, RT-PCR, and ELISA. The scores showed statistical difference after 48 weeks of treatment compared to control group. Meanwhile, volume changes of hippocampus were slight in drug treatment groups but distinct in control group; the levels of T-tau, TNF-α, and IL-1β were decreased compared to those in control group. Cistanches Herba could improve cognitive and independent living ability of moderate AD patients, slow down volume changes of hippocampus, and reduce the levels of T-tau, TNF-α, and IL-1β. It suggested that Cistanches Herba had potential neuroprotective effects for moderate AD. PMID:26435722

To evaluate the ocular dimensions in patients with primary growth hormone receptor insensitivity (Laron syndrome [LS]) and to study the effect of supplemental insulinlike growth factor I (IGF-I) on ocular growth. Retrospective case series. Twelve patients with LS, 8 untreated (LS group) and 4 treated (LS-T group) with supplemental IGF-I, and 30 healthy controls. Ocular dimensions and refraction were measured, and a full ophthalmologic examination was performed. Differences in the average ocular dimension data among IGF-I-treated patients, untreated ones, and controls. The average axial length of eyes in the LS group was 21.94 mm (standard deviation [SD], 0.81). Corresponding values for the LS-T and control group eyes were 22.53 mm (SD, 1.74) and 23.20 mm (SD, 1.35) respectively. The average anterior chamber depth of eyes in the LS group was 2.55 mm (SD, 0.26). Corresponding values for eyes in the LS-T and control groups were 3.48 mm (SD, 0.09) and 3.84 mm (SD, 0.16) respectively. The average lens thickness of eyes in the LS group was 4.56 mm (SD, 0.36). Corresponding values for the LS-T and control groups were 3.77 mm (SD, 0.23) and 3.51 mm (SD, 0.25), respectively. The average corneal curvature of eyes in the LS group was 46.9 diopters (D) (SD, 2.32). Corresponding values for the LS-T and control groups were 47.6 D (SD, 2.83) and 44.4 D (SD, 1.5), respectively. Insulinlike growth factor I seems to be an important regulator of ocular growth as documented in patients with primary growth hormone insensitivity. The mechanism of this observation should be investigated further.

To determine the efficacy of mirror therapy in children with hemiparesis. The design was an observer-blinded parallel-group randomized controlled trial (International Standard Randomised Controlled Trial Number 48748291). Randomization was computer-generated, 1:1 allocation to mirror therapy or comparison groups. The settings were home-based intervention and tertiary centre assessments. Participants were 90 children with hemiparesis aged 7 to 17 years. Intervention was 15 minutes per day of simultaneous arm training, 5 days a week, for 5 weeks. The mirror therapy group used a mirror; those in the comparison group looked at their paretic limb. Assessments comprised measures of upper limb strength, function (Melbourne Assessment 2), daily performance (ABILHAND-Kids), and sensory function at weeks 0 (T0 ), 5 (T1 ), and 10 (T2 ). There were no significant differences in outcomes and their progression over time between the mirror therapy and comparison groups. Post-hoc intention-to-treat analyses showed significant improvements in both groups for grasp strength (T0 -T1 +12.6%), pinch strength (T0 -T2 +9.1%), upper limb function in terms of accuracy (T0 -T2 +2.7%) and fluency (T0 -T2 +5.0%), as well as daily performance (T0 -T2 +16.6%). Per protocol analyses showed additional improvements in dexterity (T0 -T2 +4.0%). The use of the mirror illusion during therapy had no significant effect on treatment outcomes. However, 5 weeks of daily simultaneous arm training significantly improved paretic upper limb strength, function, and daily use. © 2016 Mac Keith Press.

Complications may occur in the subcutaneous or subdermal tissues during IV administration of chemotherapy related to blood flow and catheter placement. Daily isometric hand grip exercises were evaluated for their effect on blood flow in the vessels of the nondominant arm before placement of IV catheters and the success rate of IV catheter placement on the first attempt. The study focused on patients with non-Hodgkin lymphoma receiving the first and second cycles of chemotherapy. The intervention group performed daily isometric hand grip exercises before chemotherapy with peripheral catheter insertion. The control group performed routine activities only. Blood flow was measured by ultrasound in the brachial artery (BA) and brachial vein (BV) of the nondominant arm before the first (T1) and second (T2) cycles of chemotherapy. Blood flow slightly increased in the intervention group at T2 compared to T1. In the control group, blood flow decreased in the BA and did not change in the BV at T2 compared to T1. The success rate for first-attempt placement of a peripheral IV catheter was the same for the intervention and control groups.

This study measured the effects of including 5% NaOH-treated corn straw (T-CS) as a substitute for 15% wheat hay in the control total mixed ration (TMR) of lactating cows on performance, digestibility, and rumen microbial profile. Two groups of 21 cows each, similar in initial performance, were fed individually 1 of the 2 TMR examined. Voluntary dry matter intake of cows fed the control TMR was 4.3% higher than that of the T-CS cows, but in vivo dry matter and organic matter digestibilities of both groups were similar. Crude protein digestibility was higher in the control cows but digestibility of neutral detergent fiber polysaccharides (cellulose and hemicelluloses) was higher in the T-CS TMR. This was followed by 4.6% reduction in rumination time of the T-CS group. A slightly higher milk yield was observed in the control cows compared with the T-CS group; however, milk fat and milk protein content were higher in cows fed the T-CS TMR. This was reflected in 1.3% increase in energy-corrected milk yield and 5.34% increase in production efficiency (energy-corrected milk yield/intake) of the T-CS cows compared with the control. Welfare of the cows, as assessed by length of daily recumbence time, was improved by feeding the T-CS TMR relative to the control group. As a whole, the rumen bacterial community was significantly modulated in the T-CS group in the experimental period compared with the preexperimental period, whereas the bacterial community of the control group remained unchanged during this period. Out of the 8 bacterial species that were quantified using real-time PCR, a notable decrease in cellulolytic bacteria was observed in the T-CS group, as well as an increase in lactic acid-utilizing bacteria. These results illustrate the effect of T-CS on the composition of rumen microbiota, which may play a role in improving the performance of the lactating cow.

An intervention existing of an evidence-based medicine (EBM) course in combination with case method learning sessions (CMLSs) was designed to enhance the professional performance, self-efficacy and job satisfaction of occupational physicians. A cluster randomized controlled trial was set up and data were collected through questionnaires at baseline (T0), directly after the intervention (T1) and 7 months after baseline (T2). The data of the intervention group [T0 (n = 49), T1 (n = 31), T2 (n = 29)] and control group [T0 (n = 49), T1 (n = 28), T2 (n = 28)] were analysed in mixed model analyses. Mean scores of the perceived value of the CMLS were calculated in the intervention group. The overall effect of the intervention over time comparing the intervention with the control group was statistically significant for professional performance (p < 0.001). Job satisfaction and self-efficacy changes were small and not statistically significant between the groups. The perceived value of the CMLS to gain new insights and to improve the quality of their performance increased with the number of sessions followed. An EBM course in combination with case method learning sessions is perceived as valuable and offers evidence to enhance the professional performance of occupational physicians. However, it does not seem to influence their self-efficacy and job satisfaction.

To evaluate whether using vascular age (VA) instead of chronological age (CA) in the Framingham score would enhance the cardiovascular disease (CVD) risk estimation in patients with type 1 diabetes (T1D). This was a cross-sectional study comprising 58 T1D patients and 38 control subjects matched by age, gender and body mass index. To estimate the VA, we used carotid intima-media thickness normality estimation tables that took into account age, gender and ethnic group. Compared to the control group, T1D patients had an older VA with an 8.8-year difference (p < 0.001), a higher CVD risk stratification comparing CA and VA (p < 0.001). In the group of T1D patients, there was a 9.4-year difference between VA and CA (p < 0.001), mainly due to a greater increase in women compared to men (11.2 vs 6.4 years, respectively) and 29.3 % of the patients with T1D increased their CVD risk stratification using VA as a parameter. Still, in the group of T1D patients, women had a higher increase in VA for each 1-year increase in CA than men (1.2 years vs 0.8 years, respectively, p < 0.001). This difference persisted as we compared women with T1D with women in the control group (0.4 years), p = 0.006. T1D patients have an increased VA, a marker of subclinical atherosclerosis. The use of VA age may contribute to the identification of high CVD risk in T1D. In patients with T1D, a younger chronological age, particularly in women, might not be a protective factor for CVD.

Objective The aim of this single – blind, multicenter, parallel, randomized controlled trial was to evaluate the effectiveness of the application of a high-fluoride toothpaste on root caries in adults. Methods Adult patients (n = 130, ♂ = 74, ♀ = 56; mean age ± SD: 56.9 ± 12.9) from three participating centers, diagnosed with root caries, were randomly allocated into two groups: Test (n = 64, ♂ = 37, ♀ = 27; lesions = 144; mean age: 59.0 ± 12.1; intervention: high-fluoride toothpaste with 5000 ppm F), and Control (n = 66, ♂ = 37, ♀ = 29; lesions = 160; mean age: 54.8 ± 13.5; intervention: regular-fluoride toothpaste with 1350 ppm F) groups. Clinical examinations and surface hardness scoring of the carious lesions were performed for each subject at specified time intervals (T0 – at baseline before intervention, T1 – at 3 months and T2 – at 6 months after intervention). Mean surface hardness scores (HS) were calculated for each patient. Statistical analyses comprised of two-way analysis of variance and post hoc comparisons using the Bonferroni–Dunn correction. Results At T0, there was no statistical difference between the two groups with regard to gender (P = 0.0682, unpaired t-test), or age (P = 0.9786, chi-squared test), and for the overall HS (Test group: HS = 3.4 ± 0.61; Control group: HS = 3.4 ± 0.66; P = 0.8757, unpaired t-test). The anova revealed significantly better HS for the test group than for the control groups (T1: Test group: HS = 2.9 ± 0.67; Control group: HS = 3.1 ± 0.75; T2: Test group: HS = 2.4 ± 0.81; Control group: HS = 2.8 ± 0.79; P < 0.0001). However, the interaction term time-point*group was not significant. Conclusions The application of a high-fluoride containing dentifrice (5000 ppm F) in adults, twice daily, significantly improves the surface hardness of otherwise untreated root caries lesions when compared with the use of regular fluoride containing (1350 ppm F) toothpastes.

This study examines the effectiveness of a communication skill training based on a coaching theory for public health nurses (PHNs) who are engaged in Japan's long-term care prevention program. The participants in this study included 112 PHNs and 266 service users who met with these PHNs in order to create a customized care plan within one month after the PHNs' training. The participants were divided into three groups: a supervised group in which the PHNs attended the 1-day training seminar and the follow-up supervision; a seminar group attended only the 1-day training seminar; a control group. The PHNs' sense of performance expectancy, and user's satisfaction, user's spontaneous behavior were evaluated at the baseline (T1), at one month (T2), and at three months (T3) after the PHNs' training. At T3, the PHNs performed a recalled evaluation (RE) of their communication skills before the training. The PHNs' sense of performance expectancy increased significantly over time in the supervised group and the control group (F = 11.28, P < 0.001; F = 4.03, P < 0.05, resp.). The difference score between T3-RE was significantly higher in the supervised group than the control group (P < 0.01). No significant differences in the users' outcomes were found.

[Can dexpanthenol prevent peritoneal adhesion formation? An experimental study].

Peritoneum has an intrinsic fibrinolytic activity that breaks the peritoneal adhesions. Ischemic peritoneal injuries interfere with this fibrinolytic activity. Local application of dexpanthenol, the alcohol form of pantothenic acid (vitamin B5) accelerates wound healing by increasing mitosis. We hypothesized that dexpanthenol would decrease peritoneal adhesions. In rats, antimesenteric border of cecum was abraded with gauze. No medication was given to the control group (n=15). Dexpanthenol was administered intraperitoneally (IP) (n=15, 25 mg/kg, before abdominal closure) or intravenously (IV) (n=15, 25 mg/kg, for 9 days after operation) in the experiment groups. On postoperative day 10, adhesions were graded; activities and concentrations of tissue plasminogen activator (tPA), plasminogen activator inhibitor type 1 (PAI-1), tPA/PAI-1 complex and hydroxyproline contents were determined in peritoneum. Adhesion formation was decreased in IP dexpanthenol group compared with control group (p=0.034). tPA concentration and activity and tPA/PAI-1 complex levels were increased in the treated groups compared to controls. PAI-1 levels were similar among the three groups. Peritoneal hydroxyproline levels were lower in animals receiving IV dexpanthenol compared with control animals and in addition, they remained unchanged in IP dexpanthenol treated group (p=0.009, p=0.84, respectively). Our results suggest that dexpanthenol administration through IP may reduce peritoneal adhesion formation probably by altering peritoneal fibrinolytic activity.

Nutritional therapy is used to reduce the adverse events (AEs) of anticancer drugs. Here, we determined whether the amino acids cystine and theanine, which provide substrates for glutathione, attenuated the AEs of S-1 adjuvant chemotherapy. Patients scheduled to receive S-1 adjuvant chemotherapy were randomized to the C/T or the control groups. The C/T group received 700 mg cystine and 280 mg theanine orally 1 week before the administration of S-1, which then continued for 5 weeks. Each group received S-1 for 4 weeks. Blood sampling was performed and AEs were evaluated (CTCAE ver. 4.0) before and after the administration of S-1. S-1 was discontinued when AEs ≥ grade 2 occurred. The incidences of AEs of any grade and those over grade 2 were lower in the C/T group than in the controls. The incidence of diarrhea (G ≥ 2) was significantly less (p < 0.05) in the C/T group (3.1 %) than in the controls (25.8 %). The duration and completion rate of the S-1 adjuvant chemotherapy were significantly longer (p < 0.01) and higher (p < 0.01), respectively, in the C/T group (complete ratio: 75.0 %, duration: 24.8 ± 5.8 days) than in the controls (complete ratio: 35.5 %, duration: 20.0 ± 7.7 days). The oral administration of cystine and theanine attenuated the AEs of S-1 adjuvant chemotherapy and increased the S-1 completion rate, suggesting that cystine and theanine is a useful supportive care for chemotherapy.

The primary purpose of the study was to determine whether girls in one school receiving nurse counseling plus an after-school physical activity club showed greater improvement in physical activity, cardiovascular fitness, and body composition than girls assigned to an attention control condition in another school (N = 69). Linear regressions controlling for baseline measures showed no statistically significant group differences, but the directionality of differences was consistent with greater intervention group improvement for minutes of moderate to vigorous physical activity/hour (t = 0.95, p = .35), cardiovascular fitness (t = 1.26, p = .22), body mass index (BMI; t = -1.47, p = .15), BMI z score (t = -1.19, p = .24), BMI percentile (t = -0.59, p = .56), percentage body fat (t = -0.86, p = .39), and waist circumference (t = -0.19, p = .85). Findings support testing with a larger sample.

Effect of individualized goal-setting on college biology students' locus of control

NASA Astrophysics Data System (ADS)

Schafer, John E.

This study investigated the effect of Individualized Goal-Setting A-T, relative to Classic A-T, on a student's locus of control (generalized and academic). This study also examined the effect of pretesting, relative to no pretesting, on a student's locus of control. Sixty students in an introductory, Audio-Tutorial, college zoology course were randomly assigned to treatment and control groups. Control groups (Classic A-T) completed the course in the usual manner. Treatment groups (IGS A-T) completed the course in the usual manner with one exception. That is, they used a different format for Optional Minicourse mastery. This new format released greater control to students over means as well as ends of minicourse mastery. Data were collected through use of the Solomon Four-Group design, with two levels of treatment (Classic A-T, IGS A-T) and two levels of pretesting (pretest, no pretest). Instruments included the Rotter I-E and Schafer Academic I-E Locus of Control Scales. Posttest scores were analyzed by a 2 × 2 multivariate analysis of variance (MANOVA).The following conclusions were made (p < 0.10).1IGS A-T, relative to Classic A-T, has no significant effect on a student's locus of control.2Pretesting, relative to no pretesting, has no significant effect on posttest locus of control.

In some previous studies, vitamin B12 treatment showed immunomodulatory effects and restored the immunological abnormalities in patients with pernicious anemia (PA). In the present study, peripheral blood T cell subsets, including regulatory T cells (T(reg)s), were examined before and after vitamin B12 treatment in PA patients. The percentages of CD4, CD8, Th1, Th2 and T(reg)s were examined in 23 PA patients before vitamin B12 treatment, in 23 other PA patients after vitamin B12 treatment and in 28 healthy controls. The mean percentage of CD8+ T cells was significantly higher in the control group (23.0%; 95% CI, 20.4-25.6%) than in the pre- (16.0%; 95% CI, 12.1-20.0%) and posttreatment groups (15.2%; 95% CI, 11.8-18.6%; p < 0.05). The CD4/CD8 ratio was significantly lower in the control group (2.01; 95% CI, 1.66-2.34) than in the pre- (3.45; 95% CI, 2.55-7.80) and posttreatment groups (2.97; 95% CI, 2.22-3.72; p < 0.05). There was no significant difference in the mean Th1/Th2 ratio among these groups. There were significant increases in the mean percentage of T(reg)s in the pre- (6.29%; 95% CI, 5.04-7.54%) and posttreatment groups (7.77%; 95% CI, 6.34-9.20%) compared with the control group (4.18%; 95% CI, 3.92-4.47%; p < 0.05). The percentage of T(reg)s was significantly higher in PA patients than in normal subjects, and this high T(reg) percentage was not different before and after vitamin B12 treatment. Other immunological alterations also did not recover after vitamin B12 treatment, so that these immunological changes appear to be the cause of PA and are not induced by vitamin B12 deficiency. © 2014 S.

Type 1 diabetes mellitus (T1DM) can be associated with an increased prevalence of Helicobacter pylori infection, which could contribute to the pathogenesis of autoimmune thyroiditis observed in this disease. The aim of this study was to assess the relationship between H. pylori infection and T1DM and to identify of the interconnection between H. pylori infection and autoimmune thyroiditis in patients with T1DM. A case-control design was used. The study group included 60 children and adolescents with T1DM who were selected from the pediatric outpatient clinic of Suez Canal University Hospital by a systematic random sampling method. The control group included 60 healthy children and adolescents matched for age and sex and selected from among relatives (brothers or cousins) of the patients with T1DM. The study participants were subjected to several investigations including estimation of levels of HbA1c, thyroid stimulating hormone (TSH), T3, T4, anti-thyroglobulin (anti-Tg), and anti-thyroid peroxidase (anti-TPO). The mean age of the patients with T1DM was 12.53±2.35 years, whereas that of the control group was 12.30±1.98 years, with no statistically significant difference between the two groups. The patients with diabetes had significantly higher levels of H. pylori IgG, TSH, anti-TPO, and anti-Tg (20.43±14.84  μ/ml, 4.03±1.53 mIu/l, 14.98 ±5.04 Iu/ml, and 5.66±3.37 Iu/ml, respectively) and significantly lower levels of T3 and T4 (120±15.86 μg/dl and 4.93±0.93 μg/dl, respectively) compared with the control group. In addition, the seroprevalence rate of H. pylori, anti-Tg, and anti-TPO was significantly higher in diabetic patients, and the duration of diabetes was significantly longer in H. pylori-positive patients with higher levels of HbA1c, insulin requirement, TSH, anti-TPO, and anti-Tg. The association between H. pylori infection and autoimmune thyroiditis in patients with T1DM was revealed in this study. Hence, screening and treatment of H. pylori infection in T1DM patients is recommended.

Behavioral and psychological symptoms of dementia (BPSD) are universal and associated with multiple negative outcomes. This pilot randomized controlled trial (RCT) evaluated the effect of using the WeCareAdvisor, an innovative web-based tool developed to enable family caregivers to assess, manage, and track BPSD. This RCT enrolled 57 dementia family caregivers from community and clinical settings in Ann Arbor, Michigan and Baltimore, Maryland. Participants were randomly assigned to immediate use of the WeCareAdvisor tool (WCA, n = 27) or a Waitlist control group (n = 30) that received the tool after a one-month waiting period. Outcomes for the caregiver and the person they were caring for were assessed at baseline (T0) and one-month followup for both the WCA (T1) and Waitlist control (T2) groups. Caregiver mean age was 65.9 ± 14.0 years old. About half (49%) were spouses. Baseline characteristics were comparable between groups except for mean caregiver confidence which was higher in the control group (WCA 35.0 ± 10.0 vs. Waitlist control 39.7 ± 6.9, p = 0.04). There were no significant differences between the WCA and control groups in characteristics of the person with dementia. After their one-month of tool use (T1), WCA caregivers showed significant within group improvement in caregiver distress (- 6.08 ± 6.31 points, t = - 4.82, p < 0.0001) and behavioral frequency (- 3.60 ± 5.05, t = - 3.56, p = 0.002), severity (- 3.24 ± 3.87, t = - 4.19, p = 0.0003) and total behavioral score (- 6.80 ± 10.73, t = - 3.17, p = 004). In the same timeframe, Waitlist control caregivers showed a significant decrease in confidence (- 6.40 ± 10.30, t = - 3.40, p = 0.002). The WCA group showed greater improvement in distress compared to the Waitlist group (T0-T1; t = - 2.49, p = 0.02), which remained significant after adjusting for site and baseline distress. There were no significant between-group differences in caregiver confidence or other secondary outcomes. After their one month of tool use (T2), the Waitlist group also showed significant improvement in caregiver distress (- 3.72 ± 7.53, t = - 2.66, p = 0.013), stress (- 0.41 ± 1.02, t = - 2.19, p = 0.037), confidence (4.38 ± 5.17, t = 4.56, p < 0.0001), burden (- 2.76 ± 7.26, t = - 2.05, p = 0.05), negative communication (- 1.48 ± 2.96, t = - 2.70, p = 0.012) and behavioral frequency (- 1.86 ± 4.58, t = - 2.19, p = 0.037); distress remained significant after adjustment. In this pilot RCT, WCA use resulted in a significant decrease in caregiver distress. Future research will identify whether longer use of WCA can impact other caregiver and behavioral outcomes.

Despite advances in the medical management of type 1 diabetes mellitus (T1DM), for many, glycaemic control remains substandard. Other factors are clearly important in determining success, or lack thereof, with diabetes management. With this in mind, we have investigated whether family CHAOS may provide a novel tool to identify when environmental confusion could impact on diabetes management and subsequent glycaemic control. A case-control study of children and adolescents with established T1DM and age-/sex-matched controls was conducted. Demographic information, both maternal and paternal CHAOS scores, and HbA1c were collected. Statistical analysis was undertaken to explore associations between T1DM and CHAOS and between CHAOS and HbA1c. Data on 65 children with T1DM and 60 age-/sex-matched controls were obtained. There was no evidence of group differences for maternal CHAOS (p = 0.227), but paternal CHAOS scores were higher for the T1DM group (p = 0.041). Greater maternal and paternal CHAOS scores were both associated with higher HbA1c (p ≤ 0.027). The maternal association remained after controlling for diabetes duration, SMBG frequency, and insulin therapy. In children with T1DM, there appears to be a negative association between increased environmental confusion, as rated by CHAOS, and glycaemic control. In addition, when compared to controls, fathers of children and adolescents with T1DM appear to experience CHAOS differently to mothers. These findings contribute to the growing body of literature exploring psychosocial factors in T1DM. Continuing efforts are required to fully understand how the family and psychosocial environment interact with diabetes to impact on long-term health outcomes.

To evaluate the craniofacial changes induced by functional appliances with special regard to the oro and nasopharyngeal sagittal airway dimensions in subjects with dentoskeletal Class II malocclusions when compared with an untreated Class II control group immediately after therapy and at long-term observation. A group of 40 patients (21 females and 19 males) with Class II malocclusion treated consecutively either with a Bionator or an Activator followed by fixed appliances was compared with a matched control group of 31 subjects (16 females and 15 males) with untreated Class II malocclusion. The treated sample was evaluated at T1, start of treatment (mean age: 9.9 ± 1.4 years); T2, end of functional treatment and prior to fixed appliances (mean age: 11.9 ± 1.3 years); and T3, long-term observation at the end of growth (mean age: 18.2 ± 2.1 years). Statistical comparisons were performed with independent sample t tests at T1 (baseline characteristics) and for the T1-T2, T2-T3, and T1-T3 changes. During active treatment the treated group showed a significant increment in lower airway dimension (PNS-AD1), as well as a significant improvement in the upper airway dimension (PNS-AD2). A significant decrease in the upper adenoid size (AD2-H) was also found. In the longterm evaluation, a significant increase in both lower and upper airway thickness (PNS-AD1; PNS-AD2) and a significant decrease in the upper adenoid thickness were still present in the treated group. The treatment with functional appliances produced significant favorable changes during active treatment in the oro- and nasopharyngeal sagittal airway dimensions in dentoskeletal Class II subjects when compared with untreated controls, and these changes were stable in the long-term.

To evaluate the efficacy and safety of combined treatment of mud-bath therapy and glucosamine crystalline sulfate (GlcN-S) in patients with knee osteoarthritis (OA). This study was a randomised, controlled, crossover investigation. Patients were randomly assigned (1:1) by the investigators to two groups, named group 1 and 2. Group 1 included twenty-three patients receiving oral GlcN-S treatment from the beginning of the study (T0) to the end of the 3rd month of treatment (T3) and a combined treatment of both mud-bath therapy and GlcN-S from T3 to the end of the study at six months (T6). Group 2 included twenty-two patients receiving a combined treatment of both mud-bath therapy and GlcN-S from T0 to T3 and that discontinued mud-bath therapy, receiving GlcN-S treatment alone, from T3 to T6. Primary endpoints of the study consisted of evaluating OA severity and activity at baseline and at follow-up visits. All 45 patients, eligible for the study, completed the period of the crossover. In group 1, no significant difference was shown in the comparison from T0 to T3, while from T3 to T6 most variables were significantly improved. In group 2, instead, the comparison between T0 and T3 showed a significant difference in different parameters. When comparing T3 and T6, despite an improvement of all the variables, no significant difference was shown. The association of GlcN-S and mud-bath therapy has a positive and safe role in improving pain, function and quality of life in knee OA patients.

The aim of the present study was to elucidate possible risk factors for DHS after cervical laminoplasty. Five patients who developed DHS after cervical laminoplasty (DHS group) and twenty age-matched patients who underwent laminoplasty without DHS after surgery (control group) were compared. The surgical procedure was single-door laminoplasty with strut grafting using resected spinous processes or hydroxyapatite spacers from C3 to C6 or C7. Analyses of preoperative images including the C2-C7 angle, C7-T1 kyphosis, T1 tilt, center of gravity line from the head-C7 sagittal vertical axis (CGH-C7 SVA) were performed on lateral plain cervical spine radiographs. Preoperative T2-weighted MRI at the C5 vertebral level was used to measure the cross-sectional area of the deep extensor muscles. Widths of the lateral gutters were assessed postoperatively using CT scans of the C5 vertebral body. The average preoperative C2-C7 angle was significantly smaller in the DHS group compared with the control group. The average preoperative C7-T1 angle was significantly larger in the DHS group compared with the control group. The average preoperative CGH-C7 SVA was significantly larger in the DHS group compared with the control group. In conclusion, patients with more pronounced preoperative C2-C7 kyphosis, C7-T1 kyphosis, and CGH-C7 SVA are more likely to develop DHS following laminoplasty. Copyright © 2016.

To assess a 6-month nutritional and physical activity intervention program on the nutritional status of overweight or obese and not very active 8-14 years old children by means of a controlled pre-post design (ACTIVA'T program). Pre-post study in 8-14 years old overweight or obese and low active children from Vilafranca del Penedès (Barcelona, Spain) randomized in control group (n = 51, 47.1% girls, nutritional intervention and ≤3h/wk physical activity) and ACTIVA'T group (n = 45, 37.8% girls, nutritional and physical activity ≥5h/wk intervention). Body mass index, waist/height index, and diet quality by means of KIDMED test at the beginning and at the end of the program were assessed. During the intervention, each participant was accompanied by a relative (father or mother) who performed the same activities as the children. Dietary recommendations have positively changed the habits of both ACTIVA'T and control group. The reversion in the prevalence of overweight and obesity was 93.8% and 58.6%, respectively, in the ACTIVA'T group, compared to 25.0% and 35.8% in the control group. Abdominal obesity was decreased from 42.2% to 17.8% in the ACTIVA'T group and from 47.1% to 27.5% in the control group. The program ACTIVA'T (nutritional education and physical activity promotion) improves the quality of diet and reverses the prevalence of overweight and obesity in the underactive child population.

This study examined whether standard cognitive training, tailored cognitive training, transcranial direct current stimulation (tDCS), standard cognitive training + tDCS, or tailored cognitive training + tDCS improved cognitive function and functional outcomes in participants with PD and mild cognitive impairment (PD-MCI). Forty-two participants with PD-MCI were randomized to one of six groups: (1) standard cognitive training, (2) tailored cognitive training, (3) tDCS, (4) standard cognitive training + tDCS, (5) tailored cognitive training + tDCS, or (6) a control group. Interventions lasted 4 weeks, with cognitive and functional outcomes measured at baseline, post-intervention, and follow-up. The trial was registered with the Australian New Zealand Clinical Trials Registry (ANZCTR: 12614001039673). While controlling for moderator variables, Generalized Linear Mixed Models (GLMMs) showed that when compared to the control group, the intervention groups demonstrated variable statistically significant improvements across executive function, attention/working memory, memory, language, activities of daily living (ADL), and quality of life (QOL; Hedge's g range = 0.01 to 1.75). More outcomes improved for the groups that received standard or tailored cognitive training combined with tDCS. Participants with PD-MCI receiving cognitive training (standard or tailored) or tDCS demonstrated significant improvements on cognitive and functional outcomes, and combining these interventions provided greater therapeutic effects.

To compare clinical effect of T-shaped locking internal fixation and external fixation in treating dorsal Barton's fracture,and investigate selective strategy of internal fixation. From January 2008 to January 2013, 100 patients with dorsal Barton's fracture were randomly divided into two groups. In treatment group, there were 30 males and 20 females with an average age of (33.8±3.6) years old;30 cases were type B, 20 cases were type C;and treated with T-shaped locking internal fixation. In control group, there were 32 male and 18 females with an average age of (32.9±3.4) years old; 29 cases were type B, 21 cases were type C; and treated with external fixation. Volar tilt, ulnar deviation and radial height at 3 months after operation were detected and compared between two groups. Mechara functional evaluation were used to evaluate postoperative clinical effects. Clinical cure time, postoperative complications,joint mobility and function score were recorded and compared between two groups. In treatment group,volar tilt was (11.9±2.7)°, ulnar deviation was (20.8+ 2.9)°,and radial height was (10.9±1.8) mm; while volar tilt was (9.1±1.6)°, ulnar deviation was (17.1±2.9)°, and radial height was (8.1±1.5) mm in control group. Treatment group was better than control group in volar tilt, ulnar deviation and radial height. Clinical cure time in treatment group was(12.0±2.3) weeks, shorter than control group (18.0±4.1) weeks. The incidence of complications in treatment group was lower than control group. According to Mehara functional evaluation,20 cases got excellent results, 25 good, 3 moderate and 2 poor in treatment group; 16 cases got excellent results, 14 good, 10 moderate and 10 poor in control group. Treatment group was better than control group in clinical effects. T-shaped locking internal fixation with postoperative functional exercise for the treatment of dorsal Barton's fracture fits for biomechanics demands,and has advantages of stable fixation,rapid recovery, less complications and good functional recovery, it has better clinical effects.

Decrements in cognitive function may already be evident in young children with type 1 diabetes (T1D). Here we report prospectively acquired cognitive results over 18 months in a large cohort of young children with and without T1D. A total of 144 children with T1D (mean HbA1c: 7.9%) and 70 age-matched healthy controls (mean age both groups 8.5 years; median diabetes duration 3.9 years; mean age of onset 4.1 years) underwent neuropsychological testing at baseline and after 18-months of follow-up. We hypothesized that group differences observed at baseline would be more pronounced after 18 months, particularly in those T1D patients with greatest exposure to glycemic extremes. Cognitive domain scores did not differ between groups at the 18 month testing session and did not change differently between groups over the follow-up period. However, within the T1D group, a history of diabetic ketoacidosis (DKA) was correlated with lower Verbal IQ and greater hyperglycemia exposure (HbA1c area under the curve) was inversely correlated to executive functions test performance. In addition, those with a history of both types of exposure performed most poorly on measures of executive function. The subtle cognitive differences between T1D children and nondiabetic controls observed at baseline were not observed 18 months later. Within the T1D group, as at baseline, relationships between cognition (Verbal IQ and executive functions) and glycemic variables (chronic hyperglycemia and DKA history) were evident. Continued longitudinal study of this T1D cohort and their carefully matched healthy comparison group is planned.

Dipeptidyl peptidase‐4 (DPP‐4) inhibitors and sodium glucose co‐transporter 2 (SGLT2) inhibitors are frequently used in combination for the treatment of type 2 diabetes mellitus (T2DM). We examined the efficacy and safety of teneligliptin (a DPP‐4 inhibitor) added to canagliflozin (an SGLT2 inhibitor) monotherapy in Japanese patients with poorly controlled T2DM as part of the development of a fixed‐dose combination of teneligliptin and canagliflozin. Japanese patients treated with canagliflozin (100 mg) for ≥12 weeks were randomized to receive add‐on teneligliptin (20 mg; C + T group) or placebo (C + P group) for 24 weeks. The primary endpoint was change in glycated haemoglobin (HbA1c) from baseline to Week 24. The between‐group differences in reductions from baseline to Week 24 were significantly greater in the C + T group for HbA1c (−0.94%; P < .001). The incidence of adverse events was similar in both groups (55.8% and 49.4% in the C + T and C + P groups, respectively). No episodes of hypoglycaemia were reported. Teneligliptin added to ongoing canagliflozin monotherapy improved glycaemic control and was well tolerated in Japanese patients with inadequately controlled T2DM. PMID:28786530

Adaptations to long-term exercise training in type 1 diabetes are sparsely studied. We examined the effects of a 1-year individualized training intervention on cardiorespiratory fitness, exercise-induced active muscle deoxygenation, and glycemic control in adults with and without type 1 diabetes. Eight men with type 1 diabetes (T1D) and 8 healthy men (CON) matched for age, anthropometry, and peak pulmonary O 2 uptake, completed a 1-year individualized training intervention in an unsupervised real-world setting. Before and after the intervention, the subjects performed a maximal incremental cycling test, during which alveolar gas exchange (volume turbine and mass spectrometry) and relative concentration changes in active leg muscle deoxygenated (Δ[HHb]) and total (Δ[tHb]) hemoglobin (near-infrared spectroscopy) were monitored. Peak O 2 pulse, reflecting peak stroke volume, was calculated (peak pulmonary O 2 uptake/peak heart rate). Glycemic control (glycosylated hemoglobin A 1c (HbA 1c )) was evaluated. Both T1D and CON averagely performed 1 resistance-training and 3-4 endurance-training sessions per week (∼1 h/session at ∼moderate intensity). Training increased peak pulmonary O 2 uptake in T1D (p = 0.004) and CON (p = 0.045) (group × time p = 0.677). Peak O 2 pulse also rose in T1D (p = 0.032) and CON (p = 0.018) (group × time p = 0.880). Training increased leg Δ[HHb] at peak exercise in CON (p = 0.039) but not in T1D (group × time p = 0.052), while no changes in leg Δ[tHb] at any work rate were observed in either group (p > 0.05). HbA 1c retained unchanged in T1D (from 58 ± 10 to 59 ± 11 mmol/mol, p = 0.609). In conclusion, 1-year adherence to exercise training enhanced cardiorespiratory fitness similarly in T1D and CON but had no effect on active muscle deoxygenation or glycemic control in T1D.

Leptin and adiponectin are adipokines presenting a wide range of impacts, including glycemic balance regulations. Insulin is one of the main regulators of adipose tissue function. In type 1 diabetes mellitus (T1DM) endogenous insulin secretion is replaced by the exogenous supply, which is not regulated naturally. The aim of the study was to establish serum leptin and adiponectin levels, and their relations to body fat mass and disease course in children with T1DM. The study included 75 children with T1DM and the control group of 20 healthy coevals. All children had estimated serum leptin and adiponectin concentrations, lipid profile, and bioelectrical impedance analysis. Serum leptin concentrations in children with T1DM were not significantly different from the control group (p=0.067, mean values±SD: 3.11±2.98 vs. 5.29±5.06μg/l, respectively), and related positively to body fat mass in both groups. Adiponectin serum concentrations were significantly higher in children with T1DM than in the control group (p<0.001; mean values: 18.82±9.31 vs. 12.10±5.53μg/ml, respectively), and were not related to the body fat content in the study group. Both, leptin and adiponectin, showed no relation to any of the analyzed parameters of the disease course. Differences observed between children with T1DM and their healthy coevals, when similar in terms of age, body weight, and body fat mass, seem not to depend directly on the disease duration, its metabolic control or insulin supply.

Anabolic androgenic steroids (AASs) are synthetic analogs of testosterone often used by athletes to increase the skeletal muscle mass. Our goal was to examine the effects of physical activity and physical activity combined with supraphysiological doses of nandrolone on functional morphology of the quadriceps muscle. The study included 32 peripubertal Wistar rats, divided into 4 groups: control (T-N-), nandrolone (T-N+), physical activity (T+N-) and physical activity plus nandrolone (T+N+) groups. The T+N- and T+N+ group swam for 4 weeks, 1 h/day, 5 days/week. The T-N+ and T+N+ groups received nandolone decanoate (20 mg/kg b.w.) once per week, subcutaneously. Subsequently, the rats were sacrificed and muscle specimens were prepared for the processing. Tissue sections were histochemically and immunohistochemically stained, while the image analysis was used for quantification. Longitudinal diameter of quadriceps muscle cells was increased for 21% in T-N+, for 57% in T+N- and for 64% in T+N+ group while cross section muscle cell area was increased in T-N+ for 19%, in T+N- for 47% and in T+N+ group for 59%, compared to the control. Collagen fibers covered area was increased in T-N+ group for 36%, in T+N- for 109% and in T+N+ group for 159%, compared to the control. Erythrocyte depots were decreased in T-N+ group and increased in T+N- and T+N+ group, in comparison with T-N-. VEGF depots were increased in all treated groups. Chronic administration of supraphysiological doses of AASs alone or in combination with physical activity induces hypertrophy and significant changes in the quadriceps muscle tissue structure.

Basic trunk movement control is often impaired after stroke and its recovery is a "miliary stone" in rehabilitation. In this prospective, observational, parallel-group study, we investigated whether there are differences in terms of post-stroke recovery of basic trunk control between patients with left or with right hemiparesis. We recruited 94 patients with loss of postural trunk control due to stroke. Patients were divided into Group A (48 patients with left hemiparesis) and Group B (46 patients with right hemiparesis). We administered the Trunk Control Test (TCT) and the 13 motor items included on the Functional Independence Measure. Evaluation was performed at admission (To) and discharge (T1). TCT increased respectively from 46.7 ± 23.3 to 62.6 ± 19.5 (mean ± standard deviation-SD, p < 0.0001) in Group A and from 49.4 ± 23.2 to 79.1 ± 14.4 (mean ± SD, p < 0.0001) in Group B. TCT resulted significantly higher in Group B than in Group A, at T1 (p < 0.0001). No significant difference was found for motFIM at T1. Side of hemiparesis could affect the degree of recovery of basic trunk control after stroke. Patients with right hemiparesis benefit more than those with left hemiparesis. Improvement of basic trunk control was not responsible for an advantage on functional independence.

The aim of this study was to investigate the effects of listening to Tibetan music on anxiety and endocrine, autonomic, cognitive responses in patients waiting for urologic surgery. Sixty patients waiting for surgery were enrolled to the study. They were randomized in music (M) and control (C) groups. The M group listened to a low-frequency Tibetan music for 30 min (T 0 -T 30 ) through headphones, and the C group wore headphones with no sound. The State Trait Anxiety Inventory Questionnaire (STAI) Y-1 was administered at T 0 and T 30 . Normalized low (LFnu) and high frequencies (HFnu) of heart rate variability, LF/HF ratio, and galvanic skin response (GRS) data were analyzed at T 0 , T 10 , T 20 , T 30 , and T 35 . The salivary α -amylase (sAA) samples were collected at T 0 , T 35 , and T 45 . In the M group, the STAI Y-1 score decreased at T 30 versus baseline ( p < 0.001), sAA levels decreased at T 35 versus T 0 ( p =0.004), and GSR remained unchanged. In the C group, the STAI Y-1 score remained unchanged, sAA level increased at T 35 versus T 0 ( p < 0.001), and GSR slightly increased at T 35 versus baseline ( p =0.359). LFnu was lower, and HFnu was significantly higher (T 10 -T 30 ) in M versus C group. Mean LF/HF ratio slightly reduced in the M group. Our results suggest that preoperative listening to relaxing Tibetan music might be a useful strategy to manage preoperative anxiety.

Pulmonary tuberculosis (TB) patients often suffer from anorexia and poor nutrition, causing weight loss. The peptide hormones leptin and its counterpart ghrelin, acting in the regulation of food intake and fat utilization, play an important role in nutritional balance. This study aimed to investigate the association of blood concentrations of leptin, ghrelin and inflammatory cytokines with body mass index (BMI) in TB patients with and without type 2 diabetes mellitus (T2DM). BMI, biochemical parameters and plasma levels of leptin, ghrelin and inflammatory cytokines were measured before the start of treatment in 27 incident TB patients with T2DM, 21 TB patients and 23 healthy subjects enrolled in this study. The levels of leptin were significantly higher in TB patients (35.2 ± 19.1 ng/ml) than TB+T2DM (12.6 ± 6.1 ng/ml) and control (16.1 ± 11.1 ng/ml) groups. The level of ghrelin was significantly lower in TB (119.9 ± 46.1 pg/ml) and non-significantly lower in TB+T2DM (127.7 ± 38.6 pg/ml) groups than control (191.6 ± 86.5 pg/ml) group. The levels of TNF-α were higher, while IFN-γ and IL-6 levels were lower in patients than in the control group. Leptin showed a negative correlation with BMI in TB (r=-0.622, p<0.05) and TB+T2DM (r= -0.654, p<0.05) groups, but a positive correlation with BMI in the control group (r=0.521, p<0.05). Contrary ghrelin showed a positive correlation with BMI in TB (r=0.695, p<0.05) and TB+T2DM (r= 0.199, p>0.05) groups, but negative correlation with BMI in the control (r=-0.693, p<0.05) group. Inflammatory cytokines were poorly correlated with BMI in this study. Only IFN-γ showed a significant negative correlation with BMI in the control group (r=-0.545, p<0.05). This study may suggest that possible abnormalities in ghrelin and leptin regulation (high levels of leptin and low levels of ghrelin) may be associated with low BMI and may account for the poor nutrition associated with TB and TB+T2DM.

In a spiral task, the accuracy of the spiral trajectory, which is affected by tracing or tracking ability, differs between patients with Parkinson's disease (PD) and essential tremor (ET). However, not many studies have analyzed velocity differences between the groups during this task. This study aimed to examine differences between the groups related to this characteristic using a tablet. Fourteen PD, 12 ET, and 12 control group participants performed two tasks: tracing a given spiral (T1) and following a guiding point (T2). A digitized tablet was used to record movements and trajectory. Effects of direct visual feedback on intergroup and intragroup velocity were measured. Although PD patients had a significantly lower T1 velocity than the control group (p < 0.05), they could match the velocity of the guiding point (3.0 cm/s) in T2. There was no significant difference in the average T1 velocity between ET and the control groups (p = 0.26); however, the T2 velocity of ET patients was significantly higher than the control group (p < 0.05). They were also unable to adjust the velocity to match the guiding point, indicating that ET patients have a poorer ability to follow dynamic guidance. When both groups of patients have similar action tremor severity, their ability to follow dynamic guidance was still significantly different. Our study combined visual feedback with spiral drawing and demonstrated differences in the following-velocity distribution in PD and ET. This method may be used to distinguish the tremor presentation of both diseases, and thus, provide accurate diagnosis.

The thrombolytic treatment of stroke is limited by a narrow therapeutic time window and is associated with significant adverse side effects. To improve this situation, the modulation of tissue-type plasminogen activator (tPA) activity by a synthetic plasminogen activator inhibitor-1-derived 18-mer peptide (THR-18) was examined in two models of stroke in rats. In the first model (thromboembolic), stroke was induced by intra-carotid injection of micro-clots to rats, and tPA (6 mg/kg) was intravenously infused for 30 minutes with or without THR-18 (1 mg/kg) at 4 hours post-induction. In the second model [transient middle cerebral artery occlusion (tMCAO)], stroke was induced for 2 hours by a transient mechanical occlusion. tPA and/or THR-18 (0.02, 0.1, and 1 mg/kg) were intravenously infused for 60 minutes at the time of reperfusion. In the thromboembolic model, cerebral blood flow, measured before and up to 5.5 hours post-induction, revealed that tPA administration caused reperfusion of flow at 30 minutes post-infusion. Later on, an additional increase in reperfusion was seen in the tPA+THR-18 group, and not with tPA alone. In both models, the frequency of intracranial hemorrhage in the tPA-treated group was found to be significantly higher than the control, and this tPA effect was attenuated by THR-18. In the thromboembolic study, infarct size and brain edema were similar in the control and tPA-treated rats. However, the combination of tPA and THR-18 caused a statistically significant reduction in both parameters (infarct size 17.8 versus 25.0%, brain edema 5 versus 8%, tPA+THR-18 versus control, respectively). In the tMCAO mechanical model, infarct size and brain edema were both increased by tPA treatment as compared to the control group, and this increase was markedly diminished by THR-18 co-administration. Neurobehavioral assessment of the tMCAO animals performed at 72 hours post-stroke induction revealed significant improvements (P<0.05-0.01) in neuroscores in all groups of animals treated with peptide-tPA, as compared to the tPA monotherapy group. A significant (P<0.05) improvement in the neurological outcome was also seen in the THR-18 monoterapy group, as compared to the control animals, thus demonstrating a clear neuroprotective effect by the peptide on its own. The results support the use of THR-18 together with tPA in the thrombolytic therapy of stroke, in order to achieve better patency, less tPA-induced damage, and possibly a widening of tPA therapeutic time window.

To evaluate the effect of interventions for general practitioners and nursing home staff to improve pain severity and appropriateness of pain medication in nursing home residents (NHR). This cluster-randomized controlled trial was conducted in six nursing homes in the intervention and control group, respectively. Pain management was analysed before (T0) and after (T1, T2) an educational intervention in 239 NHR, aged ≥65 years, without moderate or severe cognitive impairment. Primary and secondary outcomes were average pain severity and appropriateness of pain medication as determined with the Numeric Rating Scale and Pain Medication Appropriateness Scale (PMASD ), respectively. At T0, 72.2% and 73.7% of NHR (mean age 83 years) reported pain (average pain severity 2.4) in the intervention and control group, respectively. The PMASD at T0 was 53.9 in the intervention group and 60.8 in the control group (p = 0.12), while 20.6% compared to 6.9% (p = 0.009) received no pain medication in the two groups. At T2, non-significant improvements in the average pain severity (1.59) and PMASD (61.07) were observed in the intervention group. Moreover, the mean individual PMASD increased by 8.09 (p = 0.03) and the proportion of NHR without pain medication decreased by 50% (p = 0.03) in the intervention group. No appreciable changes were found in the control group at T2. NHR exhibited a high prevalence of pain with overall low severity, while a high proportion of individuals received inappropriate pain medications. Both findings were not significantly improved by the intervention, although some aspects of drug treatment were meaningful improved. © 2015 European Pain Federation - EFIC®

Objectives: This study investigated the effects of post bleaching treatments to prevent restaining and the change of enamel surface microhardness after dental bleaching in vitro. Methods: Sixty intact human incisor teeth were stained in tea solution and randomly assigned into four groups (n=15). Then samples were bleached for two weeks (8 hours daily) by 15% carbamide peroxide. Tooth color was determined both with a spectrophotometer and visually before bleaching (T1) and immediately after bleaching (T2). Next, it was applied in group 1 fluoride (Naf 2%) gel for 2 minutes, and in group 2 a fractional CO2 laser (10 mJ, 200 Hz, 10 s), and in group 3, nanohydroxyapatite gel for 2 minutes. The bleached teeth in group 4 remained untreated (control group). Then teeth placed in tea solution again. Color examinations were repeated after various post bleaching treatments (T3) and restaining with tea (T4) and color change values recorded. The microhardness was measured at the enamel surface of samples. Data was analyzed using ANOVA, Tukey HSD test and Dunnett T3 (α = 0.05). Results: Directly after bleaching (ΔE T3-T2), the treatment with nanohydroxyapatite showed significantly the least color lapse in colorimetric evaluation. In experimental groups, the color change between T3 and T4 stages (ΔE T4-T3) was significantly lower than control group (P < 0.05). Different methods of enamel treatment caused a significant increase in surface microhardness compared to control group (P < 0.05). Significance: Application of fluoride, fractional CO2 laser and nanohydroxyapatite as post bleaching treatments are suggested for prevention of stain absorption and increasing the hardening of bleached enamel.

Behavioral therapies are first-line for preschoolers with attention-deficit hyperactivity disorder (ADHD). Studies support yoga for school-aged children with ADHD; this study evaluated yoga in preschoolers on parent- and teacher-rated attention/challenging behaviors, attentional control (Kinder Test of Attentional Performance [KiTAP]), and heart rate variability (HRV). This randomized waitlist-controlled trial tested a 6-week yoga intervention in preschoolers with ≥4 ADHD symptoms on the ADHD Rating Scale-IV Preschool Version. Group 1 (n = 12) practiced yoga first; Group 2 (n = 11) practiced yoga second. We collected data at 4 time points: baseline, T1 (6 weeks), T2 (12 weeks), and follow-up (3 months after T2). At baseline, there were no significant differences between groups. At T1, Group 1 had faster reaction times on the KiTAP go/no-go task (p = 0.01, 95% confidence interval [CI], -371.1 to -59.1, d = -1.7), fewer distractibility errors of omission (p = 0.009, 95% CI, -14.2 to -2.3, d = -1.5), and more commission errors (p = 0.02, 95% CI, 1.4-14.8, d = 1.3) than Group 2. Children in Group 1 with more severe symptoms at baseline showed improvement at T1 versus control on parent-rated Strengths and Difficulties Questionnaire hyperactivity inattention (β = -2.1, p = 0.04, 95% CI, -4.0 to -0.1) and inattention on the ADHD Rating Scale (β = -4.4, p = 0.02, 95% CI, -7.9 to -0.9). HRV measures did not differ between groups. Yoga was associated with modest improvements on an objective measure of attention (KiTAP) and selective improvements on parent ratings.

This study investigated the effect of different ω-6/ω-3 polyunsaturated fatty acid (PUFA) ratios on dextran sulfate sodium (DSS)-induced changes to small intestinal intraepithelial lymphocyte (IEL) γδT-cell expression. Mice were assigned to 3 control and 3 DSS-treated groups and were maintained on a low-fat semipurified diet. One of the control (S) groups and a DSS (DS) group were provided with soybean oil; the other 2 control (Hω-3 and Lω-3) groups and 2 other DSS (DHω-3 and DLω-3) groups were fed either a soybean and fish oil mixture with a ω-6/ω-3 ratio of 2:1 or 4:1. After feeding the respective diets for 2 weeks, the DSS groups were given distilled water containing 2% DSS, and the control groups were given distilled water for 5 days. All groups were further provided distilled water 5 days for recovery, and the small intestinal IEL γδT-cell subset was isolated for analysis. DSS treatment resulted in a lower small intestinal IEL γδT-cell percentage and higher messenger RNA (mRNA) expressions of Reg IIIγ, keratinocyte growth factor (KGF), and complement 5a receptor (C5aR) by IEL γδT cells. Fish oil administration enhanced the proportion of small intestinal IEL γδT cells. Compared with the DLω-3 group, the DHω-3 group had lower Reg IIIγ, KGF, and C5aR mRNA expressions and higher expression of peroxisome proliferator-activated receptor (PPAR)-γ gene by small intestinal IEL γδT cells. Fish oil diets with a ω-6/ω-3 PUFA ratio of 2:1 were more effective than those with a ratio of 4:1 in improving DSS-induced small intestinal injury, and activation of PPAR-γ in IEL γδT cells may be associated with resolution of small intestinal inflammation. © 2014 American Society for Parenteral and Enteral Nutrition.

Recent data demonstrated that individuals with type 1 diabetes mellitus (T1DM) exhibit impaired sweating and increased rectal temperature (i.e., heat storage) during exercise compared with healthy controls. Our purpose in this study was to investigate the consequences of T1DM on post-exercise thermal homeostasis. Sixteen participants (eight controls matched with eight T1DM) performed 90 min of cycling followed by 60 min of seated recovery. Esophageal and rectal temperatures, sweating (forearm, chest, and upper back), skin blood flow [forearm and upper back, presented as cutaneous vascular conductance (CVC)], and blood pressure [mean arterial pressure (MAP)] were measured at baseline and throughout recovery. Esophageal temperature was similar during baseline and recovery between groups (P = 0.88). However, rectal temperature was elevated in our T1DM group throughout recovery (P = 0.05). Sweating and CVC were similar between groups at all sites from 10-min post-exercise until the end of recovery (P ≥ 0.16). While absolute MAP was similar between groups (P = 0.43), the overall decrease in MAP post-exercise was greater in controls from 20 min (T1DM: - 8 ± 5 vs control: - 13 ± 6 mmHg, P = 0.03) until the end of recovery. We conclude that despite increased heat storage during exercise, individuals with T1DM exhibit a suppression in heat loss similar to their healthy counterparts during recovery. © 2014 John Wiley & Sons A/S.

Spine deviations and orthodontic treatment of asymmetric malocclusions in children

PubMed Central

2012-01-01

Background The aim of this randomized clinical trial was to assess the effect of early orthodontic treatment for unilateral posterior cross bite in the late deciduous and early mixed dentition using orthopedic parameters. Methods Early orthodontic treatment was performed by initial maxillary expansion and subsequent activator therapy (Münster treatment concept). The patient sample was initially comprised of 80 patients with unilateral posterior cross bite (mean age 7.3 years, SD 2.1 years). After randomization, 77 children attended the initial examination appointment (therapy = 37, control = 40); 31 children in the therapy group and 35 children in the control group were monitored at the follow-up examination (T2). The mean interval between T1 and T2 was 1.1 years (SD 0.2 years). Rasterstereography was used for back shape analysis at T1 and T2. Using the profile, the kyphotic and lordotic angle, the surface rotation, the lateral deviation, pelvic tilt and pelvic torsion, statistical differences at T1 and T2 between the therapy and control groups were calculated (t-test). Our working hypothesis was, that early orthodontic treatment can induce negative therapeutic changes in body posture through thoracic and lumbar position changes in preadolescents with uniltaral cross bite. Results No clinically relevant differences between the control and the therapy groups at T1 and T2 were found for the parameters of kyphotic and lordotic angle, the surface rotation, lateral deviation, pelvic tilt, and pelvic torsion. Conclusions Our working hypothesis was tested to be not correct (within the limitations of this study). This randomized clinical trial demonstrates that in a juvenile population with unilateral posterior cross bite the selected early orthodontic treatment protocol does not affect negatively the postural parameters.

The aim of this study was to evaluate the efficacy of autochthonous Pichia kudriavzevii as a novel bioadsorbent for aflatoxin B 1 (AFB 1 ). The selection of this yeast was based on the AFB 1 adsorption capacity previously demonstrated in vitro (Magnoli et al. 2016). One-day-old Cobb broilers (n = 160) were randomly assigned to four dietary treatments (T1: basal diet (B); T2: B + 0.1% yeast; T3: B + AFB 1 , 100 μg/kg; T4: B + 0.1% yeast + AFB 1 , 100 μg/kg). Performance parameters (average daily weight gain body, average daily consumption, feed conversion ratio, carcass weight, and dead weight), biochemical parameters (albumin, globulin, and albumin/globulin), liver pathological changes, and AFB 1 residual levels in the liver and excreta were evaluated. Significant differences (P < 0.05) in performance parameters were observed among treatments and controls: T3 group showed the lowest average daily body weight gain value while in T4 group, the value of this parameter increased significantly (P < 0.05). T3 and T4 groups showed the lowest and highest values for average daily feed consumption, respectively. The feed conversion ratio (FC) showed no significant differences among treatments. T3 group showed the lowest dead weight and carcass weight compared with T1 group. The biochemical parameters showed no significant differences among treatments. T3 group showed macroscopic and microscopic liver changes compared to the control. Aflatoxin B 1 levels (μg/g) were detected in broiler livers and showed significant differences among treatments (P < 0.05). In conclusion, native P. kudriavzevii incorporation (0.1%) in broiler diets containing AFB 1 was shown to be effective in ameliorating the adverse effects of AFB 1 on production.

To identify the effect of highly active anti-retroviral therapy (HAART) on prevention of mother to child transmission (PMTCT) of HIV and on infant growth and development. A total of 16 HIV-infected women or pregnant women selected in this study received HAART before or 18 - 24 weeks after pregnancy. The treatment included taking Zidovudine (AZT) 0.3 g each time, twice a day, Lamivudine (3TC) 0.3 g each time, once a day and Nevirapine (NVP) 0.2 g each time, twice a day or Efavirenz (EFV) 0.6 g each time, once a day, as well as labor intervention and artificial feeding. The growth index for 17 infants from HIV-infected mothers (experimental group) and 16 normal infants (control group) were observed for 18 months. Neonatal hemoglobin (Hb), liver and kidney function, serum iron and calcium were detected at neonatal period and at 12(th) month, respectively. All the pregnant women were in good conditions and had tolerance with HAART. The birth weight, length and Apgar score of the newborns in the experimental group were (3.5 ± 0.9) kg, (54.2 ± 3.8) cm and 7 - 10 scores respectively, however those in the control group were (3.6 ± 0.8) kg, (55.6 ± 3.6) cm and 8 - 10 scores (t(weight) = 1.01, t(length) = 6.98, P > 0.05). Weight and length of infants in experimental group were (9.36 ± 1.8) kg and (76.3 ± 2.7) cm at 12(th) month, while those in control group were (9.86 ± 2.5) kg and (76.8 ± 2.9) cm (t(weight) = 0.83, t(length) = 1.00, P > 0.05). The level of Hb in experimental group was (126.2 ± 16.7) g/L, and was (148.6 ± 20.5) g/L in control group (t = -5.89, P = 0.11). At 12(th) month, the levels of Hb and the total bilirubin (TB) were (125.9 ± 19.8) g/L and (11.7 ± 3.5) µmol/L in experimental group; and those in the control group were (130.1 ± 18.7) g/L and (13.2 ± 3.7) µmol/L (t(Hb) = -3.82, t(TB) = -2.14, P > 0.05). Serum iron and calcium were (25.4 ± 5.7) µmol/L and (26.4 ± 7.2) µmol/L at neonatal period and were (2.3 ± 0.6) mol/L and (2.8 ± 0.6) mol/L at 12(th) month in experimental group, while those were (26.2 ± 4.9) µmol/L and (28.1 ± 6.9) µmol/L at neonatal period and were (2.6 ± 0.5) mol/L and (3.1 ± 0.5) mol/L at 12(th) month in the control group (t(Fe) = 0.80 and t(Ca) = -3.00 in neonatal period, t(Fe) = -1.50 and t(Ca) = -1.00 at 12(th) month, P > 0.05). All infants of HIV-infected mothers were not infected with HIV when they were 18 months old. HAART can prevent mother to child transmission of HIV and it was not found to influence the baby's growth and development in this study.

To evaluate the treatment effect of an antioxidant-essential oil gel on orthodontic patients with generalized gingivitis. The gel contains the essential oils menthol and thymol and the antioxidants ferulic acid and phloretin. Thirty patients from the university's orthodontic clinic were screened for gingivitis and randomly allocated into treatment and placebo-control groups. Each patient was evaluated at three orthodontic treatment visits (T1, T2, and T3). A periodontal examination, including probing depth (PD), bleeding on probing (BOP), gingival index (GI), and plaque index (PI) was performed at each visit. Between T1 and T2, patients were instructed to apply a topical gel (active or placebo) to their gingiva twice daily after brushing. From T2 to T3, patients were instructed to discontinue use of the gel. The treatment group showed statistically significant (P < .05) reductions of BOP (-13.6 percentage points) and GI (-0.14) between T1 and T2, and significant increases in BOP (13.3 percentage points) and GI (0.14) between T2 and T3. Except for an increase in the GI between T2 and T3, the control group showed no significant changes in BOP or GI over time. The only other significant changes that occurred pertained to the treatment group, which showed significant increases in PD (0.08 mm) and PI (0.18) between T2 and T3. Application of a topical antioxidant-essential oil gel is an effective means of reducing inflammation in orthodontic patients with gingivitis.

The objective of this study is to establish a co-culture model of mouse neurons and microglial cells, and to analyze the mechanism of action of oxygen glucose deprivation (OGD) and transient oxygen glucose deprivation (tOGD) preconditioning cell models. Mouse primary neurons and BV2 microglial cells were successfully cultured, and the OGD and tOGD models were also established. In the co-culture of mouse primary neurons and microglial cells, the cell number of tOGD mouse neurons and microglial cells was larger than the OGD cell number, observed by a microscope. CCK-8 assay result showed that at 1h after treatment, the OD value in the control group is lower compared to all the other three groups (P < 0.05). The treatment group exhibited the highest OD value among the four groups. The results observed at 5h were consistent with the results at 1 h. Flow cytometry results showed that at 1h after treatment the apoptosis percentages is higher in the control group compared to other three groups (P < 0.05). Mouse brain tissues were collected and primary neurons cells were cultured. In the meantime mouse BV2 microglia cells were cultured. Two types of cells were co-cultured, and OGD and tOGD cell models were established. There were four groups in the experiment: control group (OGD), treatment group (tOGD+OGD), placebo group (tOGD+OGD+saline) and minocycline intervention group (tOGD+OGD+minocycline). CCK-8 kit was used to detect cell viability and flow cytometry was used to detect apoptosis. In this study, mouse primary neurons and microglial cells were co-cultured. The OGD and tOGD models were established successfully. tOGD was able to effectively protect neurons and microglial cells from damage, and inhibit the apoptosis caused by oxygen glucose deprivation.

Medical nutritional therapy is important for glycemic control in children and adolescents with type 1 diabetes mellitus (T1DM). Carbohydrate (carb) counting, which is a more flexible nutritional method, has become popular in recent years. This study aimed to investigate the effects of carb counting on metabolic control, body measurements and serum lipid levels in children and adolescents with T1DM. T1DM patients aged 7-18 years and receiving flexible insulin therapy were divided into carb counting (n=52) and control (n=32) groups and were followed for 2 years in this randomized, controlled study. Demographic characteristics, body measurements, insulin requirements, hemoglobin A1c (HbA1c) and serum lipid levels at baseline and at follow-up were evaluated. There were no statistically significant differences between the groups in mean HbA1c values in the year preceding the study or in age, gender, duration of diabetes, puberty stage, total daily insulin dose, body mass index (BMI) standard deviation score (SDS) and serum lipid values. While there were no differences in BMI SDS, daily insulin requirement, total cholesterol, low-density lipoprotein and triglyceride values between the two groups (p>0.05) during the follow-up, annual mean HbA1c levels of the 2nd year were significantly lower in the carb counting group (p=0.010). The mean values of high-density lipoprotein were also significantly higher in the first and 2nd years in the carb counting group (p=0.02 and p=0.043, respectively). Carb counting may provide good metabolic control in children and adolescents with T1DM without causing any increase in weight or in insulin requirements.

To investigate whether text message reminders regarding oral hygiene have an effect on plaque removal in orthodontic patients. In this randomized, controlled clinical trial, 50 orthodontic patients were assigned to either a text message or control group. Patients in the text message group received 12 text messages over the course of 4 weeks and one text message for 8 weeks thereafter. Photos were taken at baseline (T0), at 4 weeks after baseline (T1), and at 12 weeks after baseline (T2). For each subject, photos of eight teeth were taken and then the area of the tooth and amount of plaque were measured using planimetry. There was a statistically significant difference in plaque coverage between baseline and both T1 and T2 in the text message group as measured using planimetry. This was demonstrated by comparing the average measurements of the control group and the treatment group. This study demonstrated that the use of automated text message reminders sent from an orthodontic office was effective in improving oral hygiene compliance in orthodontic patients.

Changes in respiratory parameters and pulmonary function tests were evaluated after shoulder arthroscopic surgery with brachial plexus block (BPB). The purpose of this study was to identify the mechanism of respiratory dysfunction after this type of surgery. Patients undergoing arthroscopic rotator cuff repair under general anesthesia (GA) with BPB were enrolled in the arthroscopy group (n = 30) while those undergoing open reduction of a clavicle or humerus fracture under GA were enrolled in the control group (n = 30). Forced vital capacity (FVC) and forced expiratory volume 1 s (FEV(1)) were measured at the outpatient clinic stage (#1) before (#2) and 20 min after BPB (#3) and 1 h after extubation (#4). Respiratory variable measurements along with the cuff leak test were performed 5 min after surgical positioning (T1) and at the start of skin closure (T2). Respiratory discomfort was evaluated after extubation. The upper airway diameters and soft tissue depth of chest wall were also measured by ultrasonography at stages #3 and #4. Static compliance decreased significantly at T2 in the arthroscopy group (50 ± 11 at T1 vs. 44 ± 9 ml/cm H(2)O at T2, p =0.035) but not in the control group. The incidence of positive cuff leak tests at T2 was significantly higher in the arthroscopy group than in the control group (47% in the arthroscopy group vs. 17% in controls, p =0.010). While FEV(1) and FVC remained stable at stages #1 and #2, FVC and FEV(1) decreased at stages #3 and #4 only in the arthroscopy group (FVC in arthroscopy group, #2: 3.26 ± 0.77 l; #3: 2.55 ± 0.63 l, p =0.015 vs. #2; #4: 2.66 ± 0.41 l, p =0.040 vs. #2). The subglottic diameter decreased at #4 in the arthroscopy group, while no changes occurred in the control group (0.70 ± 0.21 cm vs. 0.85 ± 0.23 cm in the arthroscopy and control groups, respectively, p =0.011). Depth of skin to pleura increased at both intercostal spaces 1-2 and 3-4 in the arthroscopy group. There were three cases of hypoxia (S(p)O(2) < 95%) with room air in the arthroscopy group while none occurred in the controls. Shoulder arthroscopic surgery under GA with BPB induced both restrictive and obstructive pathologies. It is important to maintain a high level of awareness for the potential negative respiratory effects of this surgery especially for subjects with pre-existing cardiopulmonary disease. The measurements in this study would be useful to monitor the risk of respiratory dysfunction in these patients.

The specific advantage of administering systemic antibiotics during initial, non-surgical therapy or in the context of periodontal surgery is unclear. This study assesses the differential outcomes of periodontal therapy supplemented with amoxicillin-metronidazole during either the non-surgical or the surgical treatment phase. This is a single-center, randomized placebo-controlled crossover clinical trial with a 1-year follow-up. Eighty participants with Aggregatibacter actinomycetemcomitans-associated moderate to advanced periodontitis were randomized into two treatment groups: group A, antibiotics (500 mg metronidazole plus 375 mg amoxicillin three times per day for 7 days) during the first, non-surgical phase of periodontal therapy (T1) and placebo during the second, surgical phase (T2); and group B, placebo during T1 and antibiotics during T2. The number of sites with probing depth (PD) >4 mm and bleeding on probing (BOP) per patient was the primary outcome. A total of 11,212 sites were clinically monitored on 1,870 teeth. T1 with antibiotics decreased the number of sites with PD >4 mm and BOP per patient significantly more than without (group A: from 34.5 to 5.7, 84%; group B: from 28.7 to 8.7, 70%; P <0.01). Twenty patients treated with antibiotics, but only eight treated with placebo, achieved a 10-fold reduction of diseased sites (P = 0.007). Consequently, fewer patients of group A needed additional therapy, the mean number of surgical interventions was lower, and treatment time in T2 was shorter. Six months after T2, the mean number of residual pockets (group A: 2.8 ± 5.2; group B: 2.2 ± 5.0) was not significantly different and was sustained over 12 months in both groups. Giving the antibiotics during T1 or T2 yielded similar long-term outcomes, but antibiotics in T1 resolved the disease quicker and thus reduced the need for additional surgical intervention.

To compare the effectiveness of Doctor Tecar TherapyTM with that of laser therapy in the management of low back pain (LBP), a total of 60 patients with LBP were enrolled. The participants were randomly divided into two groups: a Tecar group (experimental group, 30 subjects), and a laser group (control group, 30 subjects). All the subjects received 10 sessions of therapy: one each day from Monday to Friday and the same again the following week. All the subjects were evaluated for pain (VAS) and disability (Roland and Morris score and Oswestry score) at baseline (T0), and 2 weeks (T1), 1 month (T2) and 2 months (T3) after the end of treatment. The pain and disability presented a trend to improvement over time in both groups. This improvement was statistically significant at all follow-ups (FUs) in the Tecar group but only at T1 for the Laser group (p less than 0.01). Comparing the two methods, there emerged a significant difference in favour of the Tecar group at T2 and T3 (p less than 0.01). The results show that Tecar therapy determined significant improvement already by the end of the treatment. Moreover, at the first and second month FUs, the Tecar therapy showed statistically better results than laser therapy.

The objective of the present study was to investigate whether dietary selenium (Se) deficiency would affect the expression of selenoprotein T (SelT) and immune response in the immune organs of broilers. Changes in expression of inflammatory cytokines and oxidative stress response caused by Se deficiency can lead to organism damage, which in turn leads to immune response. Sixty (1-day-old) broilers were divided into the control group and Se-deficiency group. Animal models with exudative diathesis were duplicated in the broilers by feeding them Se-deficient diet for 20 days. After the Se-deficient group exhibited symptoms of exudative diathesis, all the broilers were euthanized, and their immune organs were taken for analysis. The tissues including spleen, bursa of Fabricius, and thymus were treated to determine the pathological changes (including microscopic and ultramicroscopic), the messenger RNA (mRNA) expression levels of SelT and its synthetase (SecS and SPS1), cytokine mRNA expression levels, and antioxidant status. The microscopic and ultramicroscopic analyses showed that immune tissues were obviously injured in the Se-deficient group. The mRNA expression of SelT was decreased compared with that in the control group. Meanwhile, the mRNA expression levels of SecS and SPS1 were downregulated. In the Se-deficient group, the mRNA expression levels of IL-1R and IL-1β were higher than those of three control organs. Additionally, the IL-2 and INF-γ mRNA expression levels were lower than those of the control group. The activity of CAT was decreased, and the contents of H 2 O 2 and •OH were increased due to Se deficiency. Pearson method analysis showed that the expression of SelT had a positive correlation with IL-2, INF-γ, SecS, and SPS1 and a negative correlation with IL-1R and IL-1β. In summary, these data indicated that Se-deficient diet decreased the SelT expression and its regulation of oxidative stress, and it inhibited a pleiotropic mechanism of the immune response.

Optimal therapeutics for hyperthyroidism-induced osteoporosis are still lacking. As a noninvasive treatment, electromagnetic fields (EMF) have been proven to be effective for treating osteoporosis in non-hyperthyroidism conditions. We herein systematically evaluated the reduced effects of EMF on osteoporosis in a hyperthyroidism rat model. With the use of Helmholtz coils and an EMF stimulator, 15 Hz/1 mT EMF was generated. Forty-eight 5-month-old male Sprague-Dawley rats were randomly divided into four different groups: control, levothyroxine treated (L-T4), EMF exposure + levothyroxine (EMF + L-T4), and EMF exposure without levothyroxine administration (EMF). All rats were treated with L-T4 (100 mg/day) except those in control and EMF groups. After 12 weeks, the results obtained from bone mineral density analyses and bone mechanical measurements showed significant differences between L-T4 and EMF + L-T4 groups. Micro CT and bone histomorphometric analyses indicated that trabecular bone mass and architecture in distal femur and proximal tibia were augmented and restored partially in EMF + L-T4 group. In addition, bone thyroid hormone receptors (THR) expression of hyperthyroidism rats was attenuated in EMF + L-T4 group, compared to control group, which was not observed in L-T4 group. According to these results, we concluded that 15 Hz/1 mT EMF significantly inhibited bone loss and micro architecture deterioration in hyperthyroidism rats, which might occur due to reduced THR expression caused by EMF exposure.

This study investigated the combined effect of fractional CO(2) laser irradiation and fluoride on treatment of enamel caries. Sixty intact premolars were randomly assigned into four groups and then stored in a demineralizing solution to induce white spot lesions. Tooth color was determined at baseline (T1) and after demineralization (T2). Afterwards, the teeth in group 1 remained untreated (control), while group 2 was exposed to an acidulated phosphate fluoride (APF) gel for 4 min. In groups 3 and 4, a fractional CO(2) laser was applied (10 mJ, 200 Hz, 10 s) either before (group 3) or through (group 4) the APF gel. The teeth were then immersed in artificial saliva for 90 days while subjected to daily fluoride mouthrinse and weekly brushing. Color examinations were repeated after topical fluoride application (T3) and 90 days later (T4). Finally, the teeth were sectioned, and microhardness was measured at the enamel surface and at 30 and 60 μ from the surface. In both lased groups, the color change between T1 and T4 stages (∆E(T1-T4)) was significantly lower than those of the other groups (p < 0.05). Laser irradiation followed by fluoride application (group 3) caused a significant increase in surface microhardness compared to APF alone and control groups (p < 0.05). Microhardness at depths of 30 and 60 μ was also significantly greater in group 3 compared to those of all other groups (p < 0.05). Application of a fractional CO(2) laser before fluoride therapy is suggested for recovering the color and rehardening of demineralized enamel.

The dipeptidyl-peptidase-IV (DPP-4) inhibitors, including sitagliptin, are used for the treatment of type 2 diabetes mellitus (T2DM). Adiponectin, an adipocyte-derived circulating protein, has anti-atherosclerotic and anti-diabetic properties and is effectively elevated in bloodstream by thiazolidinediones, an insulin sensitizer. However, the effect of sitagliptin treatment on serum adiponectin level in T2DM has not fully elucidated in Japanese T2DM patients. The aim of the present study was to examine the effect of sitagliptin treatment on serum adiponectin levels in T2DM subjects. Twenty-six consecutive Japanese T2DM outpatients were recruited between April 2011 and March 2013, and randomized into the control (conventional treatment, n = 10) group and sitagliptin treatment group (n = 16). Serum adiponectin was measured by enzyme-linked immunosorbent assay. Indices of glycemic control, such as hemoglobin A1c, glycated albumin, and 1.5-anhydro-D-glucitol, were significantly improved after the three-month treatment in both the control and sitagliptin groups. Serum adiponectin level was significantly increased in sitagliptin group from 6.7 ± 0.8 to 7.4 ± 1.0 μg/mL without change of body mass index (p = 0.034), while serum adiponectin level was not altered in the control group (p = 0.601). In Japanese T2DM patients, serum adiponectin level was elevated by three-month treatment with sitagliptin without change of body weight. UMIN000004721.

The aim of this study was to describe the impact of a tailored Web-based educational program designed to reduce excessive screening mammography recall. Radiologists enrolled in one of four mammography registries in the United States were invited to take part and were randomly assigned to receive the intervention or to serve as controls. The controls were offered the intervention at the end of the study, and data collection included an assessment of their clinical practice as well. The intervention provided each radiologist with individual audit data for his or her sensitivity, specificity, recall rate, positive predictive value, and cancer detection rate compared to national benchmarks and peer comparisons for the same measures; profiled breast cancer risk in each radiologist's respective patient populations to illustrate how low breast cancer risk is in population-based settings; and evaluated the possible impact of medical malpractice concerns on recall rates. Participants' recall rates from actual practice were evaluated for three time periods: the 9 months before the intervention was delivered to the intervention group (baseline period), the 9 months between the intervention and control groups (T1), and the 9 months after completion of the intervention by the controls (T2). Logistic regression models examining the probability that a mammogram was recalled included indication of intervention versus control and time period (baseline, T1, and T2). Interactions between the groups and time period were also included to determine if the association between time period and the probability of a positive result differed across groups. Thirty-one radiologists who completed the continuing medical education intervention were included in the adjusted model comparing radiologists in the intervention group (n = 22) to radiologists who completed the intervention in the control group (n = 9). At T1, the intervention group had 12% higher odds of positive mammographic results compared to the controls, after controlling for baseline (odds ratio, 1.12; 95% confidence interval, 1.00-1.27; P = .0569). At T2, a similar association was found, but it was not statistically significant (odds ratio, 1.10; 95% confidence interval, 0.96 to 1.25). No associations were found among radiologists in the control group when comparing those who completed the continuing medical education intervention (n = 9) to those who did not (n = 10). In addition, no associations were found between time period and recall rate among radiologists who set realistic goals. This study resulted in a null effect, which may indicate that a single 1-hour intervention is not adequate to change excessive recall among radiologists who undertook the intervention being tested.

Problems like postoperative pain are still common phenomena after general anesthesia. Oxycodone hydrochloride is a semisynthetic opioid with a safe and excellent therapeutic effect on visceral pain. Flurbiprofen axetil has the efficacy of targeted analgesia. We hypothesize that different doses of oxycodone hydrochloride combined with flurbiprofen axetil would generate great results on postoperative intravenous analgesia in lower abdominal patients. In the clinical trial, 90 American Society of Anesthesiologists I or II patients scheduled for elective general anesthesia were randomly divided into 3 groups, 30 cases in each group. Group I: oxycodone hydrochloride 0.5 mg/kg + flurbiprofen axetil 150 mg, group II: oxycodone hydrochloride 0.75 mg/kg + flurbiprofen axetil 150 mg, group III: oxycodone hydrochloride 1.0 mg/kg + flurbiprofen axetil 150 mg. Dilute them with 0.9% saline to 150 mL, respectively, with the background dose of 2 mL/h, patient-controlled analgesia 2 mL per time, with an interval of 10 min, and the loading dose of 0.1 mL/kg. Record the preoperative situation, 24 h (T0) before surgery, postoperative situation, 1 h (T1), 4 h (T2), 8 h (T3), 12 h (T4), 24 h (T5), 48 h (T6), 72 h (T7) after the surgery, including the mean arterial pressure, heart rate, saturation of pulse oximetry, static and dynamic pain rating (NRS) and Ramsay sedation score, effective pressing and total pressing ratio (referred to as the pressing ratio), patient satisfaction, and occurrence of adverse reactions. There was no significant statistic difference in mean arterial blood pressure, heart rate, arterial oxygen saturation, and adverse reactions among the 2 groups at each time point (P > .05). Compared with group I, the static NRS rating in group II and group III were significantly lower than that in group I (P < .05) from T1 to T5. The dynamic NRS rating of group II from T1 to T4 and that of group III from T1 to T5 were significantly lower (P < .05). The effective pressing and total pressing ratio was significantly higher (P < .05). There was no significant statistic difference between group II and group III in NRS rating and the effective pressing and total pressing ratio (P > .05). Compared with group III, the Ramsay sedation scores of group I and group II were significantly lower from T1 to T4 (P < .05). The dose of 0.75 mg/kg oxycodone hydrochloride combined with flurbiprofen axetil can provide safe and effective postoperative analgesia for lower abdominal patients, with fewer adverse reactions.

Longitudinal investigation of natural killer cells and cytokines in chronic fatigue syndrome/myalgic encephalomyelitis

PubMed Central

2012-01-01

Background Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is an etiologically unexplained disorder characterised by irregularities in various aspects of the immunological function. Presently, it is unknown whether these immunological changes remain consistent over time. This study investigates Natural Killer (NK) cell cytotoxic activity, NK cell subsets (CD56brightCD16- and CD56dimCD16+) and cytokines, over the course of a12 month period in patients with CFS/ME. Methods The participants in the study comprised 65 (47.2 ± 11.5 years) CFS/ME participants and 21 (45.2 ±9.3 years) non-fatigued controls. Flow cytometry protocols were used to assess NK subsets and NK cytotoxic activity at various time points that included baseline (T1), 6 (T2) and 12 months (T3). Cytokine secretions were measured following mitogenic stimulation of peripheral blood mononuclear cells. Results NK cytotoxic activity was significantly decreased in the CFS/ME patients at T1, T2 and T3 compared to the non-fatigued group. Additionally, in comparison to the non-fatigued controls, the CFS/ME group had significantly lower numbers of CD56brightCD16- NK cells at both T1 and T2. Interestingly, following mitogenic stimulation, cytokine secretion revealed significant increases in IL-10, IFN-γ and TNF-α at T1 in the CFS/ME group. A significant decrease was observed at T2 in the CFS/ME group for IL-10 and IL-17A while at T3, IL-2 was increased in the CFS/ME group in comparison to the non-fatigued controls. Overall cytotoxic activity was significantly decreased at T3 compared to T1 and T2. CD56brightCD16- NK cells were much lower at T2 compared to T1 and T3. IL-10 and IL-17A secretion was elevated at T2 in comparison to T1 and T3. Conclusion These results confirm decreases in immune function in CFS/ME patients, suggesting an increased susceptibility to viral and other infections. Furthermore, NK cytotoxic activity may be a suitable biomarker for diagnosing CFS/ME as it was consistently decreased during the course of the 12 months study. PMID:22571715

National guidelines recommend adolescents achieve 60 minutes of moderate-to-vigorous physical activity (MVPA)/day, yet few adolescents meet these guidelines. We piloted a novel quasi-randomized physical activity intervention to promote adolescent's use of their surrounding built environment among 30 intervention and 30 control overweight/obese adolescents aged 10-16 years living in greater Boston from 2013 to 2015. Location-specific MPVA was measured by accelerometry and global positioning system for three one-week periods (Time 1 [T1], Time 2 [T2], and Time 3 [T3]). One month after T1, intervention participants received individualized counseling on how to use their surrounding built environment to increase MVPA, and control participants received standard-of-care lifestyle modification counseling; both groups received their T1 physical activity data. T2 assessment occurred the week after the counseling visit and T3 assessment 3-4 months later. The main outcome was change in average daily minutes of MVPA; the secondary outcome was meeting national MVPA guidelines. Multivariable modeling accounted for covariates (baseline MVPA, body mass index, age, sex, race/ethnicity) and clustering by study group and town. Among the 60 adolescents recruited, 55 (92%) completed data collection. Short-term (T2) intervention effects included increased average MVPA of +13.9 minutes intervention versus -.6 minutes control (p < .0001). Differential increase in mean daily MVPA was sustained at T3 (9.3 minutes more in intervention group; p = .0006). The proportion of adolescents in the intervention group who achieved 60 minutes/day of MVPA increased from 11% (T1) to 21% (T2), whereas declining (7%-0%) among controls. Individualized counseling about the built environment can help increase MVPA among overweight and obese adolescents. Copyright © 2016 Society for Adolescent Health and Medicine.

Lambs were assigned to four groups of seven and treated as follows for 12 days: control group (BP) was fed beet pulp; group T (tannin remedy) received the BP diet including 80 g/kg of quebracho extract; group S (saponin remedy) received the BP diet including 15 g/kg of quillaja extract; and group C had a free choice between T and S remedies. Lipid oxidation was lower in meat from S lambs compared to T lambs (P<0.05). Among the volatile compounds, lactate was lower in meat from S lambs compared to T animals (P=0.05). Metabolomic analysis showed that the T treatment increased ribose, fructose, glucose and sorbitol concentration in meat (P<0.05), while cholesterol was decreased by S and C treatments. The T treatment increased the concentration of C14:1 cis-9 (P<0.05). These findings indicate that treatments for parasite control containing tannins and saponins do not detrimentally affect sheep meat quality. © 2013.

The aim was to test the effectiveness of early home-based group education on knowledge and communication about renal replacement therapy (RRT). We conducted a randomized controlled trial using a cross-over design among 80 end-stage renal disease (ESRD) patients. Between T0 and T1 (weeks 1-4) Group 1 received the intervention and Group 2 received standard care. Between T1 and T2 (weeks 5-8) Group 1 received standard care and Group 2 received the intervention. The intervention was a group education session on RRT options held in the patient's home given by social workers. Patients invited members from their social network to attend. Self-report questionnaires were used at T0, T1 and T2 to measure patients' knowledge and communication, and concepts from the Theory of Planned Behaviour such as attitude. Comparable questionnaires were completed pre-post intervention by 229 attendees. Primary RRT was registered up to 2 years post-intervention. Multilevel linear modelling was used to analyse patient data and paired t-tests for attendee data. Statistically significant increases in the primary targets knowledge and communication were found among patients and attendees after receiving the intervention. The intervention also had a significant effect in increasing positive attitude toward living donation and haemodialysis. Of the 80 participants, 49 underwent RRT during follow-up. Of these, 34 underwent a living donor kidney transplant, of which 22 were pre-emptive. Early home-based group education supports informed decision-making regarding primary RRT for ESRD patients and their social networks and may remove barriers to pre-emptive transplantation. © The Author 2015.

Hawthorn is a popular herb in many different traditional medicine systems, including traditional Chinese medicine, where it has long been used for the treatment of hyperglycemia. However, most of its varied biological activities remain unexplored. This study investigated the hypoglycemic effect of hawthorn extracts in type II diabetic (T2DM) rat model. A total of 54 rats were randomly divided into six groups: normal control group; type II diabetic model group (T2DM; these rats were induced by high-fat diet and streptozotocin); high, middle and low concentrations of hawthorn treatment (HT H , HT M and HT L T2DM rats were given hawthorn extract at a dose of 50, 100 and 200 mg kg -1 body weight, respectively); and positive control group (orlistat 40 mg kg -1 body weight). Triglyceride and total cholesterol serum levels were lower in the hawthorn extract-treated groups than in the T2DM control group (P < 0.01). Furthermore, hawthorn extracts decreased blood glucose level and increased plasma insulin release from pancreas. Positive effects of hawthorn against streptozotocin-induced T2DM were demonstrated. This study suggests that hawthorn extract represents a useful agent for the prevention or treatment of T2DM. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

INTRODUCTION: Type 1 diabetes mellitus (T1DM) is one of the most common chronic diseases in children that may be complicated by micro or macrovascular complications. Measurement of the carotid intima-media thickness (CIMT) allows the early detection of atherosclerotic alterations of blood vessels that may complicate T1DM. SUBJECTS AND METHODS: This study is a case-control study. Participants were classified into two groups. The first group included 40 children with T1DM and the second group included 30 matched healthy controls. The studied cases were recruited from Endocrinology and Diabetology Unit, Pediatric Hospital, Ain Shams University. Serum apelin, cholesterol, TG, LDL were measured for every case. Also, albumin level was analyzed in urine. Measurement of the carotid intima-media thickness (CIMT) was done for all cases. RESULTS: Comparison between T1DM patients and controls revealed that serum apelin, cholesterol, TG, LDL and albuminuria were significantly increased in cases compared to controls. Significant positive correlations were detected between HbA1C, albuminuria and lipid profile with apelin in the diabetic group (p < 0.05). CIMT has significant positive correlation with serum apelin levels (r = 0.36, p = 0.05). Also, this study found positive correlations between CIMT and some variables as LDL, SBP z-score and duration of the illness. CONCLUSION: Increased levels of serum apelin in T1DM patients may be considered as predicting factor for the ongoing development of vascular sequels. This study highlighted the possible validity of apelin assay as an early predictor of atherosclerosis in T1DM children. Evaluating CIMT in these patients is of at most important for early detection of subclinical atherosclerosis. PMID:29731925

Objectives The objective was to evaluate the clinical efficiacy of a constant rate infusion of heated fluid as the sole means of preventing intraoperative hypothermia in cats. Methods This randomised, prospective, clinical study was conducted at a university teaching veterinary hospital. Female cats (American Society of Anesthesiologists [ASA] grade I) undergoing elective surgery by laparotomy under general anaesthesia (acepromazine 0.05 mg/kg SC; morphine 0.2 mg/kg IV; propofol IV titrated, isoflurane 2% in 100% oxygen) were randomised in two groups. Both groups were infused with fluid (NaCl 0.9%, 5 ml/kg/h) either at room temperature (control group) or prewarmed at 43°C (warmed group) using an Astoflo Plus eco (Stihler Electronic) fluid heating device. No other heating device was used. Temperature, heart rate, respiratory rate and SpO 2 were evaluated after induction (T0) and every 15 mins for 1 h (T15, T30, T45, T60). Mean arterial blood pressure was recorded every 30 mins (T0, T30 and T60). Results Thirty-four female cats (ASA grade I) were enrolled in the study. There was no difference in age, weight, propofol dose or room temperature (22.4 ± 1.1°C vs 22.0 ± 1.5°C; P = 0.363) between control and warmed groups, respectively. In both groups, oesophageal temperature significantly decreased during anaesthesia ( P <0.0001). The temperature decrease after 1 h was -3.6 ± 0.7°C in the warmed group and was not significantly different from the control group (-3.4 ± 0.7°C; P = 0.307). The slopes of the temperature decrease did not significantly differ between the two groups (-0.058 ± 0.013°C/min vs -0.060 ± 0.010°C/min for the control and warmed groups, respectively; P = 0.624). Conclusions and relevance This study provides clinical evidence that a constant rate infusion of heated fluid alone fails to prevent intraoperative hypothermia in cats. The low infusion rate (5 ml/kg/h) could partly explain the ineffectiveness of this active warming device in minimising or delaying the onset of intraoperative hypothermia.

Resistance Training Improves Muscle Function and Cardiometabolic Risks But Not Quality of Life in Older People With Type 2 Diabetes Mellitus: A Randomized Controlled Trial.

In older people with type 2 diabetes mellitus (T2DM), the effects of aging and T2DM may compromise the function of skeletal muscle, deteriorate metabolic status, and jeopardize physical performance, aerobic capacity, and quality of life (QoL). The purpose of this study was to investigate the effects of 12 weeks of resistance training (RT) on muscle function, physical performance, cardiometabolic risks, and QoL in older people with T2DM. This study was a randomized controlled trial that employed block randomization, assessor blinding, and the intention-to-treat principle. Thirty people 65 years or older with a diagnosis of T2DM were randomly assigned to either an exercise group or a control group and were further stratified by gender. The exercise group performed 8 RT exercises in 3 sets of 8 to 12 repetitions at 75% 1-repetition maximum (1-RM) 3 times per week for 12 weeks. The control group received usual care and maintained their daily activities and lifestyle. Muscle function (1-RM and muscle oxygenation responses), physical performance (5-repetition sit-to-stand test and Timed Up and Go test), cardiometabolic risks (aerobic capacity, blood pressure, body composition, glycemic control, lipids levels, and high-sensitivity C-reactive protein levels), and QoL (Audit of Diabetes-Dependent Quality of Life 19) were assessed at baseline (week 0) and after the 12-week interventions (week 12). The 1-RM chest-press and leg-press strength and physical performance in 5-repetition sit-to-stand test were significantly improved in the exercise group compared with the controls after the interventions. The exercise group had significantly lower resting systolic blood pressure (by -12.1 mm Hg, P = 0.036) than did the controls after 12 weeks of RT, without any significant within-group change in either group after intervention. The waist circumference, fasting glucose levels, and peak diastolic blood pressure tended to favor RT over usual care after the interventions. Twelve weeks of RT increased the maximal strength in chest-press and leg-press tests, and improved 5-repetition sit-to-stand performance in older people with T2DM. Our study demonstrated that supervised, structured RT was able to promote muscle function and alleviate cardiometabolic risks in people with T2DM 65 years or older.

Caffeine is an adenosine receptor antagonist and a possible cause of inadequate stress perfusion. Splenic switch-off (SSO) and splenic rest-stress T1-mapping have been proposed as indicators of stress adequacy during perfusion cardiac magnetic resonance (CMR). We compared myocardial rest-stress T1-mapping with SSO and splenic rest-stress T1-mapping in patients with and without recent coffee intake. We analyzed 344 consecutive patients suspected of myocardial ischemia with adenosine perfusion CMR. All 146 normal CMR studies with a normal T1-rest of the myocardium, used as standard of reference, were included and divided in two groups. 22 patients accidentally ingested coffee < 4 h before CMR, compared to control group of 124 patients without self-reported coffee intake. Two independent readers graded SSO visually. T1-reactivity (ΔT1) was defined as percentual difference in T1-rest and T1-stress. Follow-up data were extracted from electronic patients records. In patients with recent coffee intake SSO was identified in 96%, which showed no significant difference with SSO in controls (94%, p = 0.835), however event rates were significantly different (13.6 and 0.8%, respectively (p < 0.001), median FU 17 months). Myocardial ΔT1 in the coffee group (- 5.2%) was significantly lower compared to control (+ 4.0%, p < 0.001), in contrast to the splenic ΔT1 (- 3.7 and - 4.0%, p = 0.789). The splenic T1-mapping results failed to predict false negative results. SSO and splenic rest-stress T1-mapping are not reliable indicators of stress adequacy in patients with recent coffee intake. Therefore, the dark spleen sign does not indicate adequate myocardial stress in patients with recent caffeine intake. Myocardial rest-stress T1-mapping is an excellent indicator of stress adequacy during adenosine perfusion CMR.

The impact of the investigational human immunodeficiency virus type 1 (HIV-1) F4/AS01B vaccine on HIV-1 viral load (VL) was evaluated in antiretroviral therapy (ART)-naive HIV-1 infected adults.This phase IIb, observer-blind study (NCT01218113), included ART-naive HIV-1 infected adults aged 18 to 55 years. Participants were randomized to receive 2 (F4/AS01B_2 group, N = 64) or 3 (F4/AS01B_3 group, N = 62) doses of F4/AS01B or placebo (control group, N = 64) at weeks 0, 4, and 28. Efficacy (HIV-1 VL, CD4 T-cell count, ART initiation, and HIV-related clinical events), safety, and immunogenicity (antibody and T-cell responses) were evaluated during 48 weeks.At week 48, based on a mixed model, no statistically significant difference in HIV-1 VL change from baseline was demonstrated between F4/AS01B_2 and control group (0.073 log10 copies/mL [97.5% confidence interval (CI): -0.088; 0.235]), or F4/AS01B_3 and control group (-0.096 log10 copies/mL [97.5% CI: -0.257; 0.065]). No differences between groups were observed in HIV-1 VL change, CD4 T-cell count, ART initiation, or HIV-related clinical events at intermediate timepoints. Among F4/AS01B recipients, the most frequent solicited symptoms were pain at injection site (252/300 doses), fatigue (137/300 doses), myalgia (105/300 doses), and headache (90/300 doses). Twelve serious adverse events were reported in 6 participants; 1 was considered vaccine-related (F4/AS01B_2 group: angioedema). F4/AS01B induced polyfunctional F4-specific CD4 T-cells, but had no significant impact on F4-specific CD8 T-cell and anti-F4 antibody levels.F4/AS01B had a clinically acceptable safety profile, induced F4-specific CD4 T-cell responses, but did not reduce HIV-1 VL, impact CD4 T-cells count, delay ART initiation, or prevent HIV-1 related clinical events.

The study was conducted to evaluate the effect of early physical rehabilitation by comparing the differences of surface electromyographic (sEMG) activity in the masseter and anterior temporalis muscles after surgical correction of skeletal class III malocclusion. The prospective study included 63 patients; the experimental groups contained 31 patients who received early systematic physical rehabilitation; the control group (32 patients) did not receive physiotherapy. The amplitude of sEMG in the masticatory muscles reached 72.6-121.3% and 37.5-64.6% of pre-surgical values in the experimental and control groups respectively at 6 weeks after orthognathic surgery (OGS). At 6 months after OGS, the sEMG reached 135.1-233.4% and 89.6-122.5% of pre-surgical values in the experimental and control groups respectively. Most variables in the sEMG examination indicated that recovery of the masticatory muscles in the experimental group was better than the control group as estimated in the early phase (T1 to T2) and the total phase (T1 to T3); there were no significant differences between the mean recovery percentages in the later phase (T2 to T3). Early physical rehabilitative therapy is helpful for early recovery of muscle activity in masticatory muscles after OGS. After termination of physical therapy, no significant difference in recovery was indicated in patients with or without early physiotherapy.

The interaction of FAS/FAS ligand (FASL) serves an important role in the upregulation of apoptotic processes through different mechanisms in cells. Previous studies have established that the polymorphisms FAS -670A/G and FASL -844C/T are associated with risk of generalized aggressive periodontitis (GAP) in different ethnic populations. Therefore, in the present study, it was investigated for the first time whether FAS -670A/G and FASL -844C/T polymorphisms were associated with risk of GAP in Iran. This case-control study performed the polymerase chain reaction-restriction fragment length polymorphism method in 25 patients with GAP and 110 normal subjects as controls. The results indicated that there was no significant difference in FAS -670A/G genotype frequency between the GAP and control groups. A higher frequency of the combined genotype (AG+GG) was observed in the GAP patients (96.0%) compared with the control subjects (90.9%), though this was not significant [χ 2 =0.705, degrees of freedom (df)=1, P=0.401]. Similarly, the prevalence of the G allele was non-significantly higher in the GAP group (62.0%) compared with that in the controls (60.0%; χ 2 =0.012, df=1, P=0.913). For FASL-844C/T polymorphism, the frequency of the combined genotype (CT+TT) was higher in the GAP group (96.0%) when compared with the control subjects (91.8%); however its association was not statistically significant (χ 2 =0.519, df=1, P=0.471). The frequency of the T allele only marginally differed between the groups, being 60.0% in the GAP group and 50.9% in the controls (χ 2 =3.627, df=1, P=0.057). These results indicated that there were no significant associations between the FAS -670A/G and FASL -844C/T polymorphisms and the risk of disease in GAP patients when compared with normal individuals.

The objective of this study was to explore the influence of the renin-angiotensin system on cardiac prooxidants and antioxidants levels and its association to autonomic imbalance induced by hyperthyroidism. Male Wistar rats were divided into four groups: control, losartan (10mg/kg/day by gavage, 28 day), thyroxine (T4) (12 mg/L in drinking water for 28 days), and T4+losartan. Spectral analysis (autonomic balance), angiotensin II receptor (AT1R), NADPH oxidase, Nrf2 and heme-oxygenase-1 (HO-1) myocardial protein expression, and hydrogen peroxide (H2O2) concentration were quantified. Autonomic imbalance induced by hyperthyroidism (~770%) was attenuated in the T4+losartan group (~32%) (P<0.05). AT1R, NADPH oxidase, H2O2, as well as concentration, Nrf2 and HO-1 protein expression were elevated (~172%, 43%, 40%, 133%, and 154%, respectively) in T4 group (P<0.05). H2O2 and HO-1 levels were returned to control values in the T4+losartan group (P<0.05). The overall results demonstrate a positive impact of RAS blockade in the autonomic control of heart rate, which was associated with an attenuation of H2O2 levels, as well as with a reduced counter-regulatory response of HO-1 in experimental hyperthyroidism.

HIV elite controllers suppress HIV viremia without antiretroviral therapy (ART), yet previous studies demonstrated that elite controllers maintain an activated T-cell phenotype. Chronic immune activation has detrimental consequences and thus ART has been advocated for all elite controllers. However, elite controllers are not a clinically homogenous group. Since CD4% is among the best predictors of AIDS-related events, in the current study, we assessed whether this marker can be used to stratify elite controllers needing ART. Sixteen elite controllers were divided into two groups based on CD4% (EC > 40% and EC ≤40%), and T-cell subsets were analyzed for markers of memory/differentiation (CD45RA, CCR7, CD28), activation (CD38/HLA-DR), immunosenescence (CD57), costimulation (CD73, CD28) and exhaustion (PD-1, CD160, Tim-3). Monocyte subsets (CD14, CD16) were also analyzed and sCD14 levels were quantified using ELISA. In the EC group, expression of activation, exhaustion, and immunosensescence markers on T cells were significantly reduced compared with the EC group and similar to the seronegative controls. The EC group expressed higher levels of costimulatory molecules CD28 and CD73 and had lower levels of monocyte activation (HLA-DR expression) with a reduced frequency of inflammatory monocyte (CD14 CD16) subset. Furthermore, the EC group maintained a stable CD4% during a median follow-up of 6 years. Elite controllers with preserved CD4T cells (EC) have normal T-cell and monocyte phenotypes and therefore may have limited benefit from ART. CD4% can be an important marker for evaluating future studies aimed at determining the need for ART in this group of individuals.

C.S.F. samples of 35 patients, who suffered from verified chronic, non-tumorous organic brain syndrome, were radioimmunoassayed for T4 and T.S.H., and were compared to C.S.F.-R.I.A. samples from a control group of patients who underwent myelography because of lumbar disc. In addition T4 and T.S.H. plasma levels were evaluated in the O.B.S. patients. C.S.F. T4 and T.S.H. levels were significantly higher in 65% of the O.B.S. group of patients than those of the control group. The average determinations for T4 were: 0.77 muh/100 ml in O.B.S. group as against 0--0.4 micrograms/100 ml in the C.S.F.'s of the control group. P greater than 0,001 T.S.H. C.S.F. levels were 1.33 microU/ml in the O.B.S. group, and 0--0.6 microU/ml in the control group (P greater than 0.005). It is suggested that the elevated R.I.A. values of these hormones in the C.S.F. of the O.B.S. patients reflect a disruption of blood-C.S.F. barriers. Therefore in the organic brain syndrome there seems to exist a pathophysiological dysfunction of brain barriers in addition of the neural damage.

To determine exposure to hyper- and hypoglycemia using blinded continuous glucose monitoring (CGM) profiles in youth with type 1 diabetes (T1D) with residual β-cell function during the first year of insulin treatment. Blinded, 3-7 day CGM profiles were obtained in 16 short-term T1D patients (age 8-18 years, T1D duration 6-52 weeks) who had peak C-peptide levels ranging from 0.46 to 1.96 nmol/L during a mixed-meal tolerance test. Results in this short-term group were compared with those in 34 patients with well-controlled, longer-term T1D (duration ≥5 years), matched for age and A1C with the short-term T1D group, and with those in 26 age-matched nondiabetic individuals. Despite matching for A1C, and therefore similar mean sensor glucose levels in the two T1D groups, short-term T1D participants had a lower frequency of hypoglycemia (0.3 vs. 7.6%, P < 0.001), a trend toward less hyperglycemia (17 vs. 32%, P = 0.15), and a greater percentage in the target range (median 77 vs. 60%, P = 0.02). Indeed, the percentage of sensor glucose levels ≤70 mg/dL in the short-term T1D group (0.3%) did not differ from those in the nondiabetic group (1.7%, P = 0.73). The coefficient of variation of sensor glucose levels (an index of glucose variability) was lower in short-term vs. longer-term T1D participants (27 vs. 42%, respectively, P < 0.001). In youth with short-term T1D who retain residual β-cell function, there is negligible exposure to hypoglycemia and lower glucose variability than in youth with well-controlled T1D of longer duration.

This prospective study was aimed to determine and quantify the change in mandibular condylar hyperactivity over a period of time by using a fluorine-18 (18F) fluoride PET-computed tomography (CT) scan. Sixteen patients (age 19.50 ± 2.58 years) with noticeable faciomandibular asymmetry caused by unilateral condylar hyperplasia (UCH) were included in the test group and underwent an 18F-fluoride PET-CT scan at the beginning of the study (T0); these patients were then followed up for a minimum of 12 months, after which the 18F-fluoride PET-CT scan was repeated at first follow-up (T1). An age-matched control group consisted of 10 patients with apparently symmetrical faces whose PET-CT scans were acquired for some other medical conditions. Statistical analysis of maximum standardized uptake values (SUV max) obtained through 18F-fluoride PET-CT was performed using the paired t-test. Mean SUV max of the affected condyle at T0 and T1 was 9.18 ± 4.07 and 9.18 ± 3.88, respectively. The mean SUV max of the contralateral condyle at T0 and T1 was 6.21 ± 2.30 and 6.66 ± 2.64, respectively. The mean right-left difference in tracer uptake between the test and control groups both at T0 and T1 was statistically significant. Right-left percentage difference of isotope uptake of the test group was 16.87 ± 15.75% at T0 and 14.97 ± 12.72% at T1. Right-left percentage difference of isotope uptake of the control group was 5.51 ± 5.72%. Although these differences were statistically significant, their clinical relevance was insignificant. SUV max of the higher uptake side and the lower uptake side of the control group was 5.63 ± 1.85 and 5.09 ± 1.83, respectively. Great diversity exists in the clinical presentation of UCH. The growth trend of UCH is highly variable because of the age and sex of patients. The results of the present study show that the 18F-fluoride PET-CT scan may guide us in determining the right time and in making the right choice of surgico-orthodontic intervention in UCH patients. The clinical presentation and SUV max of PET-CT of UCH patients were in agreement with each other. The baseline values of the control group indicated that these could also be used to differentiate normal from abnormal condylar growth in potential class III skeletal pattern cases - that is, patients having sagittal skeletal dysplasia resulting from either maxillary deficiency or mandibular protrusion, or both in combination, thus resulting in a concave facial profile.

Magnetic resonance (MR) imaging provides a unique, noninvasive diagnostic platform to quantify the physiological and biochemical variables of skeletal muscle at rest. This study was to investigate the difference in thigh skeletal muscles between snowboarding halfpipe athletes and healthy volunteers via multiparametric MR imaging. A comparative study was conducted between 12 healthy volunteers and 14 snowboarding halfpipe athletes. MR scanning targeted the left leg at the level of the proximal thigh on a 3.0T MR system. The measured parameters compared between the two groups included T1, T2, T2* relaxation times, fat fraction (FF), and cross-sectional area (CSA) of the quadriceps femoris and the hamstring muscles. Statistical analysis was carried out using independent sample t-test. Interrater reliability was also assessed with intraclass correlation coefficients (ICCs). It was statistically equivalent between two groups in age, body mass index, thigh circumference, calf circumference, systolic blood pressure, and resting heart rate (all P > 0.05). However, the T1 and T2 values of the hamstring muscles in the athlete group were found to be significantly shorter than those in control group (T1: 1063.3 ± 24.1 ms vs. 1112.0 ± 38.2 ms in biceps femoris, 1050.4 ± 31.2 ms vs. 1095.0 ± 39.5 ms in semitendinosus, 1053.1 ± 31.7 ms vs. 1118.4 ± 40.0 ms in semimembranosus, respectively; T2: 33.4 ± 0.7 ms vs. 36.1 ± 1.9 ms in biceps femoris, 34.6 ± 2.0 ms vs. 37.0 ± 1.9 ms in semitendinosus, 36.9 ± 1.5 ms vs. 38.9 ± 2.4 ms in semimembranosus, respectively; all P < 0.05) although T2* relaxation time was detected with no significant difference. The FF of the hamstring muscles was obviously less than the control group (5.5 ± 1.9% vs. 10.7 ± 4.7%, P < 0.001). In addition, the quadriceps' CSA in the athlete group was substantially larger than the control group (8039.0 ± 1072.3 vs. 6258.2 ± 852.0 mm 2 , P < 0.001). Interrater reliability was excellent (ICC: 0.758-0.994). Multiple MR imaging parameters indicated significant differences between snowboarding halfpipe athletes and healthy volunteers in the thigh skeletal muscles.

The control of hypertensive patients' blood pressure and heart rate using vasoconstrictors during surgical procedures under anesthesia is still a major concern in everyday surgical practice. This clinical trial aimed to evaluate the variation of blood pressure and heart rate in nonhypertensive and controlled hypertensive voluntary subjects undergoing oral surgery under local anesthesia with lidocaine hydrochloride and epinephrine at 1:100,000 (Alphacaine; DFL, Brazil), performed in the Oral Surgery Department, Dentistry School, Fluminense Federal University. In total, 25 voluntary subjects were divided into 2 groups: nonhypertensive (n = 15) and controlled hypertensives (n = 10). Blood pressure and heart rate were measured at 4 different times: T0, in the waiting room; T1, after placement of the surgical drapes; T2, 10 minutes after anesthesia injection; and T3, at the end of the surgical procedure. A statistically significant difference (P < 0.05) between the groups was found at times T0 and T2 for the systolic pressure but only at time T0 for the diastolic pressure. The assessment of the heart rate of both groups showed a statistically significant difference (P < 0.05) at time T1. An analysis of the employed anesthetic volume indicated no statistically significant difference (P > 0.05) between the amount administered to nonhypertensive and hypertensive subjects. It was concluded that the local anesthetics studied could safely be used in controlled hypertensive and nonhypertensive patients in compliance with the maximum recommended doses.

In order to investigate the relationship between gut microbiota and type 2 diabetic erectile dysfunction (T2DED), we analyzed the characteristics of gut microbiota in the Sprague-Dawley (SD) rats with T2DED. Thirty-five SD rats were randomly divided into two groups: control group (n=15) with normal diet, and experimental group (n=20) with construction of T2D model. Faecal and serum samples were collected at 2nd and 8th week after establishment of T2D model, respectively. Faecal samples were used for analysis of gut microbiota, and serum samples for detection of trimethylamine N-oxide (TMAO), lipopolysaccharide (LPS), and inflammatory factors like interleukin-1 (IL-1), IL-2, IL-10, and monocyte chemoattractantprotein-1 (MCP-1). The main compositions of gut microbiota were Bacteroidetes, Proteobacteria and Firmicutes at the phylum level, and Oscillospira, Allobaculum, Bacteroides, Ruminococcus, SMB53, Prevotella, Coprococcus, Sutterella and Blautia at the genus level with relatively higher abundance in all SD rats. The relative abundance of Enterococcus, Corynebacterium, Aerococcus, Facklamia (opportunistic pathogens in most case) increased, and that of Allobaculum, Bifidobacterium, Eubacterium, Anaerotruncus (beneficial bacteria) decreased in T2DED group as compared with that at 2nd week after establishment of T2D model (T2D2 group). The serum contents of TMAO, LPS, IL-1, IL-2, IL-10 and MCP-1 in T2DED group were significantly higher than those in control group. The gut microbiota of T2DED rats was inhibited. The gut microbiota of T2DED rats had changed, as the relative abundance of beneficial bacterium was decreased while that of opportunistic pathogens was increased. The variations of gut microbiota might lead to inflammation and prompt the emergence of erectile dysfunction in the rats with T2D. TMAO might play an important role in the formation of T2DED.

To investigate the association between C421T polymorphism within exon 4, C575T polymorphism within exon 6 of the RANK gene and bone mineral density (BMD) variations in postmenopausal Turkish women. One hundred seventy-eight postmenopausal women (patients = 100 and controls = 78) who applied to Ege University Faculty of Medicine, Department of Physical Medicine and Rehabilitation, for osteoporosis examination were analyzed. BMDs of the lumbar spine and femoral sites were measured. Patient and control groups were established based on their T-score values being above and/or below -1. After venous blood sampling, C421T and C575T polymorphisms of the RANK gene were assessed through PCR process following DNA extraction. Genotype frequencies for the C421T and C575T polymorphisms were compared between the control group and the patient group. No significant difference was detected between the two groups for both polymorphisms. There was also no significant difference between the control and patient groups in terms of the combined genotype (p = 0.752) and the combined haplotype analysis of the C421T and C575T polymorphisms (p = 0.723). In the control and patient groups separately, no significant differences in BMD values either at the femoral sites or at the lumbar spine were detected between the combined genotypes of the two polymorphisms. The genotypes, combined genotypes and allele frequencies of C421T and C575T polymorphisms of the RANK gene have not been found to be associated with BMD in Turkish women. Further studies including both sexes and more cases are required.

There is growing interest in t'ai chi, but little research has addressed whether t'ai chi is effective in older people using wheelchairs for mobilization. The aim of this study was to compare the effects of seated t'ai chi exercise and usual standard activities on mood states and self-efficacy in older people living in a long-term care facility and using wheelchairs for mobilization. Randomized controlled trial (trial registration no. ACTRN12613000029796). One long-term-care facility in Taiwan. Sixty participants were randomly assigned by a computer-generated random sequence to a t'ai chi group (n = 30) or a usual exercise and entertainment activities group (n = 30). Seated t'ai chi exercise for 40 minutes three times a week for 26 weeks was provided. Mood states (Profile of Mood States Short Form [POMS-SF]) and self-efficacy (Self-Efficacy for Exercise [SEE]). At week 26, participants in the t'ai chi group reported significantly lower mood states on the fatigue-inertia dimension of the POMS-SF (mean score ± standard deviation, 3.56 ± 3.71) than did the control group (mean score, 7.16 ± 6.36) (F [1, 58] = 7.15; p < 0.05). The t'ai chi group recorded significantly higher SEE levels (mean, 35.66 ± 36.83) than did those in the control group (mean, 15.30 ± 26.43) (F [1, 58] = 6.05; p < 0.05). The findings highlight the importance of t'ai chi for a reduction in the fatigue-inertia mood state and an increase in self-efficacy for older people using wheelchairs.

The role of mobile technology in patient-reported outcomes (PRO) and glycemic control in adults with type 1 diabetes (T1D) needs further evaluation. The single-center, prospective, 6-month, open-label, investigator-initiated study randomized 100 subjects with T1D in a 1:1 fashion to a control group using self-monitoring of blood glucose (SMBG) with Accu-Chek Nano ® and an intervention group using SMBG with iPhone plus glucose meter (iBGStar ® ). The primary endpoint was the change in PRO (hypoglycemia fear score, behavior and worry subscores). Secondary outcomes were the improvement in glycemic variability indices and the reduction in A1c values. Baseline demographics and glycosylated hemoglobin (A1c) values were similar in the two groups. There was a significant decrease in A1c value at 6 months in iBGStar ® group compared to the control group (-0.16 vs. -0.51, p = 0.04). The total insulin dose increased significantly in the iBGStar ® group at 3 months but did not change at 6 months. The hypoglycemia fear scale (PRO) improved in both groups at 6 months (-1.4 ± 10.0 vs. -3.9 ± 12.5, p = 0.32). The use of iBGStar ® resulted in better glycemic control and improvement in some PRO (hypoglycemia fear and behavior scores) compared to the control group at 6 months with no increased risk of hypoglycemia.

Objectives To test the hypothesis that powered wheelchair users who receive the Wheelchair Skills Training Program (WSTP) improve their wheelchair skills in comparison with a Control group that receives standard care. Our secondary objectives were to assess goal achievement, satisfaction with training, retention, injury rate, confidence with wheelchair use and participation. Design Randomized controlled trial (RCT). Setting Rehabilitation centers and communities. Participants 116 powered wheelchair users. Intervention Five 30-minute WSTP training sessions. Main Outcome Measures Assessments were done at baseline (T1), post-training (T2) and 3 months post-training (T3) using the Wheelchair Skills Test Questionnaire (WST-Q 4.1), Goal Attainment Score (GAS), Satisfaction Questionnaire, Injury Rate, Wheelchair Use Confidence Scale for Power Wheelchair Users (WheelCon) and Life Space Assessment (LSA). Results There was no significant T2-T1 difference between the groups for WST-Q capacity scores (p = 0.600) but the difference for WST-Q performance scores was significant (p = 0.016) with a relative (T2/T1 x 100%) improvement of the median score for the Intervention group of 10.8%. The mean (SD) GAS for the Intervention group after training was 92.8% (11.4) and satisfaction with training was high. The WST-Q gain was not retained at T3. There was no clinically significant difference between the groups in injury rate and no statistically significant differences in WheelCon or LSA scores at T3. Conclusions Powered wheelchair users who receive formal wheelchair skills training demonstrate modest transient post-training improvements in their WST-Q performance scores, they have substantial improvements on individualized goals and they are positive about training.

To investigate the effect of Echinococcus multilocularis cyst fluid on five MAPK (mitogen-activated protein kinase)-pathway genes of rat hepatic stellate cell. Rat hepatic stellate cell line, HSC-T6 cells were co-cultured with different protein concentrations of E. multilocularis cyst fluid (0.01, 0.025, 0.05, 0.1, 0.2, 0.4, 0.9, 1.7, 3.4, 6.8, and 13.5 mg/ml) for 24 h. HSC-T6 cells cultured with complete medium served as control group. The morphological change of cells was observed under the microscope. The expression of extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and mitogen-activated protein kinase(p38) in HSC-T6 cells was detected by real time fluorescent quantitative PCR. After co-cultured for 24 h, most HSC-T6 cells in 13.5 mg/ml group shrank as a precursor to slough off; In 6.8 mg/ml group, some HSC-T6 cells shrank and changed to long fusiform shape with many slender pseudopodia; In 3.4 mg/ml group, most HSC-T6 cells showed as adherent cells with an irregular polygon shape, formed a sheet with short pseudopodia. There was no difference in cell morphology between < 1.7 mg/ml groups and control group. When the protein concentration was above 1.7 mg/ml, the mRNA level of ERK1/2, JNK1/2, and P38 increased significantly increased. In 6.8 mg/ml cyst fluid group, the mRNA level of ERK1/2, JNK1/2, and P38 was higher than that of the control (P < 0.05). 6.8 mg/ml Echinococcus multilocularis cyst fluid can have a significant impact on mRNA levels of ERK1/2, JNK1/2 and p38 in rat hepatic stellate cells.

Even though patients with type 1 diabetes mellitus (T1DM) are exempted from fasting, the vast majority elect to fast against the advice of their healthcare providers. We have previously reported the incidence of wide fluctuations in blood glucose (BG) along with "unrecognized" severe hypoglycemia during Ramadan fasting in adolescents with T1DM. This report compares the continuous glucose monitoring (CGM) data during fasting in adolescents with T1DM according to their Pre-Ramadan diabetes control. Children and adolescents with T1DM who intended to fast the month of Ramadan were asked to wear the CGM during fasting for a minimum of 3 days. Hypoglycemia, hyperglycemia, and severe hyperglycemia were identified as BG <70 mg/dL (3.9 mmol/L), BG 201-300 mg/dL (11.2-16.7 mmol/L), or BG >300 mg/dL (16.7 mmol/L) respectively, while normoglycemia was identified as BG 70-200 mg/dL (3.9-11.1 mmol/L). Patients were categorized as well-controlled (Group 1) and poorly controlled (Group 2) if the pre-fasting HbA1C was ≤8% (64 mmol/mol) and >8%, respectively. We compared the mean BG and the percentages of time spent in hypoglycemia, hyperglycemia, and severe hyperglycemia between the two groups using Chi-square (significant difference when P value was <0.05). A total of 21 patients were enrolled (15 females), age 15 ± 4 years, duration of diabetes 6 ± 3 years, and HbA1C 8.5 ± 1.0% (70 mmol/mol). There were 7 subjects in Group 1, mean HbA1C 7.5 ± 0.4, and 14 subjects in Group 2, mean HbA1C 9.1 ± 0.9. The mean ± SD BG was 174 ± 76 mg/dL versus 199 ± 98, (P < 0.05) in Group 1 and Group 2, respectively. The percentages of hypoglycemia, hyperglycemia, and severe hyperglycemia were significantly higher in Group 2, while there was a higher percentage of normoglycemia in Group 1. The overall durations of hypoglycemia, hyperglycemia, and severe hyperglycemia in Group 2 were longer by 30, 14, and 135%, respectively, than those in Group 1. Glycemic control before Ramadan in adolescents with T1 DM appears to correlate with blood glucose profile during Ramadan fasting. Our data suggest that optimal glycemic control before Ramadan may reduce the potential risks associated with fasting and minimize glucose fluctuation.

Study Protocol: The Norfolk Diabetes Prevention Study [NDPS]: a 46 month multi - centre, randomised, controlled parallel group trial of a lifestyle intervention [with or without additional support from lay lifestyle mentors with Type 2 diabetes] to prevent transition to Type 2 diabetes in high risk groups with non - diabetic hyperglycaemia, or impaired fasting glucose.

This 7 year NIHR programme [2011-2018] tests the primary hypothesis that the NDPS diet and physical activity intervention will reduce the risk of transition to type 2 diabetes (T2DM) in groups at high risk of Type 2 diabetes. The NDPS programme recognizes the need to reduce intervention costs through group delivery and the use of lay mentors with T2DM, the realities of normal primary care, and the complexity of the current glycaemic categorisation of T2DM risk. NDPS identifies people at highest risk of T2DM on the databases of 135 general practices in the East of England for further screening with ab fasting plasma glucose and glycosylated haemoglobin [HbA1c]. Those with an elevated fasting plasma glucose [impaired fasting glucose or IFG] with or without an elevated HbA1c [non -diabetic hyperglycaemia; NDH] are randomised into three treatment arms: a control arm receiving no trial intervention, an arm receiving an intensive bespoke group-based diet and physical activity intervention, and an arm receiving the same intervention with enhanced support from people with T2DM trained as diabetes prevention mentors [DPM]. The primary end point is cumulative transition rates to T2DM between the two intervention groups, and between each intervention group and the control group at 46 months. Participants with screen detected T2DM are randomized into an equivalent prospective controlled trial with the same intervention and control arms with glycaemic control [HbA1c] at 46 months as the primary end point. Participants with NDH and a normal fasting plasma glucose are randomised into an equivalent prospective controlled intervention trial with follow up for 40 months. The intervention comprises six education sessions for the first 12 weeks and then up to 15 maintenance sessions until intervention end, all delivered in groups, with additional support from a DPM in one treatment arm. The NDPS programme reports in 2018 and will provide trial outcome data for a group delivered diabetes prevention intervention, supported by lay mentors with T2DM, with intervention in multiple at risk glycaemic categories, and that takes into account the realities of normal clinical practice.

Objective An intervention existing of an evidence-based medicine (EBM) course in combination with case method learning sessions (CMLSs) was designed to enhance the professional performance, self-efficacy and job satisfaction of occupational physicians. Methods A cluster randomized controlled trial was set up and data were collected through questionnaires at baseline (T0), directly after the intervention (T1) and 7 months after baseline (T2). The data of the intervention group [T0 (n = 49), T1 (n = 31), T2 (n = 29)] and control group [T0 (n = 49), T1 (n = 28), T2 (n = 28)] were analysed in mixed model analyses. Mean scores of the perceived value of the CMLS were calculated in the intervention group. Results The overall effect of the intervention over time comparing the intervention with the control group was statistically significant for professional performance (p < 0.001). Job satisfaction and self-efficacy changes were small and not statistically significant between the groups. The perceived value of the CMLS to gain new insights and to improve the quality of their performance increased with the number of sessions followed. Conclusion An EBM course in combination with case method learning sessions is perceived as valuable and offers evidence to enhance the professional performance of occupational physicians. However, it does not seem to influence their self-efficacy and job satisfaction. PMID:18386046

To evaluate effects of intensive insulin treatment modalities on cardiovascular biomarkers in patients with type 1 diabetes mellitus (T1DM). A total of 25 patients with T1DM receiving intensive insulin therapy either in the form of continuous insulin pump (IP group; n=13) or as multiple daily injections (MDI group; n=12) and 13 controls (control group, n=13) were included. Data on demographics, anthropometrics, diabetes history, and laboratory findings including glycemic and lipid parameters, and cardiovascular biomarkers [C-reactive protein (mg/dL), homocysteine (μmol/L), fibrinogen (mg/dL), oxidized LDL (ng/dL), PAI-1 (ng/mL), MCP-1 (pg/mL) and VEGF (pg/mL)] were recorded in each group. Correlation of cardiovascular biomarkers to other parameters was also evaluated in T1DM patients. Apart from significantly higher mean (SD) values for HbA1c [6.1 (0.3) vs. 5.6 (0.5)% (43 (3) vs. 38 (5) mmol/mol), p<0.05)] and HDL-cholesterol [71.5 (13.6) vs. 58.2 (10.8), p<0.01) in the IP than in the MDI group, no significance difference was noted between insulin treatment modalities as well as between patient and control groups in terms of demographic, anthropometric and laboratory parameters. Negative correlation of MCP-1 to treatment duration (r=-0.615, p=0.025), and HDL-c to CRP (r=-0.685, p=0.010) and VEGF (r=-0.678, p=0.011) was noted in IP group, whereas positive correlation of PAI-1 to diabetes age (r=0.805, p=0.002) and treatment duration was noted in MDI group. Our findings in a cohort of T1DM patients with optimal glycemic control revealed that intensive insulin therapy was not associated with an increase in atherosclerotic markers in T1DM, regardless of whether continuous IP infusion or MDIs was administered.

To evaluate the effectiveness of hypnotic and musical relaxation therapy and psychological consultation for parents of children with cleft lip and/or palate (CLP) and to provide a scientific basis of clinical-psychological treatment options. Sixty-six subjects with children with CLP participated in this study. The subjects were randomly assigned to a test group (n = 33) and a control group (n = 33). The test group was treated with hypnotic and musical relaxation therapy; the control group were subjected to psychological consultation. Anxiety and depression states were evaluated by using a self-rating anxiety scale (SAS) and a self-rating depression scale (SDS) before and after treatment was administered. 1) The test group demonstrated a significant decrease in SAS and SDS scores (t = 2.855, P < 0.01; t = 2.777, P < 0.01). The control group showed a significant decrease in the SAS score (t = 1.831, P < 0.05) but failed to show a significant change in the depression score (t = 0.909, P > 0.05). 2) The test group yielded a higher percentage of remission indicated by the SDS scores than the control group (test group = 75.76%; control group = 60.61%; P < 0.05). The test group also displayed a higher percentage of remission indicated by the SAS scores than the control group (test group = 78.79%, test group = 69.70%; P < 0.05). Hypnotic and musical relaxation therapy can more effectively reduce the scores of the anxiety and depression states of the parents of patients with cleft lip and/or palate than psychological consultation.

This study aimed to investigate the association of salinomycin and semduramicin, in different doses, against controlled mixed infection of Eimeria acervulina, E. maxima and E. tenella in broiler chickens. Eight hundred birds were divided into 5 groups (T1: not medicated feed; T2: 30 ppm of salinomycin and 12.5 ppm of semduramicin; T3: 30 ppm of salinomycin and 15 ppm of semduramicin; T4: 40 ppm of salinomycin and 12,5 ppm of semduramicin and T5: 40 ppm of salinomycin and 15 ppm of semduramicin) and inoculated at 15 days of age with sporulated oocysts of E. acervulina, E. maxima and E. tenella in a mixed suspension, through the feed. Performance data and lesion scores were recorded. All treated groups showed statistically better cumulative weight gain at 21 days old. At 35 days old only the T3 group showed significant difference. Cumulative feed conversion showed statistical difference in the groups T4 and T5. The treatment T5 was more effective in the coccidiosis control of E. tenella. T3 and T5 achieved statistical differences in the average lesion scores of the three analyzed species. The association of salinomycin and semduramicin used in lower doses than the usual, showed to be an option in the coccidiosis control in this experiment.

In human immunodeficiency virus (HIV)-infected individuals the amount of antibodies formed after vaccination with T-cell-dependent recall antigens such as tetanus toxoid is proportional to the peripheral blood CD4+ T-lymphocyte counts. To investigate whether the immunoglobulin G (IgG) subclass distribution and avidity of the antibodies produced after vaccination are affected as well, we gave 13 HIV-infected adults with low CD4+ T-lymphocyte counts (<200 × 106/liter; group I), 11 HIV-infected adults with intermediate CD4+ T-lymphocyte counts (≥200 × 106/liter; group II), and 5 healthy controls booster immunizations with tetanus toxoid. The prevaccination antibody concentrations against tetanus toxoid were similar in the HIV-infected and healthy adults. After vaccination the total IgG and the IgG1 anti-tetanus toxoid antibody concentrations were significantly lower in group I than in group II and the controls. The avidity of the IgG1 anti-tetanus toxoid antibodies formed by HIV-infected adults was within the range for healthy controls, irrespective of their CD4+ T-lymphocyte counts. PMID:10225835

When Atlantic salmon parr migrate from fresh water towards the sea, they undergo extensive morphological, neural, physiological and behavioural changes. Such changes have the potential to affect their responsiveness to various environmental factors that impose stress. In this study we compared the stress responses in parr and post-smolt salmon following exposure to repeated chasing stress (RCS) for three weeks. At the end of this period, all fish were challenged with a novel stressor and sampled before (T0) and after 1h (T1). Parr had a higher growth rate than post-smolts. Plasma cortisol declined in the RCS groups within the first week suggesting a rapid habituation/desensitisation of the endocrine stress axis. As a result of the desensitised HPI axis, RCS groups showed a reduced cortisol response when exposed to the novel stressor. In preoptic area (POA) crf mRNA levels were higher in all post-smolt groups compared to parr. 11βhsd2 decreased by RCS and by the novel stressor in post-smolt controls (T1), whereas no effect of either stress was seen in parr. The grs were low in all groups except for parr controls. In pituitary, parr controls had higher levels of crf1r mRNA than the other parr and post-smolt groups, whilst pomcb was higher in post-smolt control groups. Overall, 11βhsd2 transcript abundance in parr was lower than post-smolt groups; after the novel stressor pomcs, grs and mr were up-regulated in parr control (T1). In summary, we highlight differences in the central stress response between parr and post-smolt salmon following RCS. Copyright © 2015 Elsevier Inc. All rights reserved.

The aim of this study was to investigate the effect of active non-weight-bearing (NWB) group exercising on women with non specific chronic low back pain (NSCLBP). Forty females with NSCLBP were assigned in a randomized control longitudinal single blinded pilot study. 20 of them were assigned to a NWB bi-weekly group exercise class and 20 females were included in the control group. The exercises involved the entire lumbo-pelvic spine aimed at improving lumbar mobility/flexibility and stability. Pain intensity (VAS), back specific disability (Rolland Morris questionnaire-RMQ), and lumbar flexion and extension ranges of motion measurements were taken prior to intervention (t(0)), immediately following 4 weeks of intervention (t(1)) and 8 weeks later (t(fu)). Reliability trials were conducted on 10 females. Non-parametric tests were used for statistical significance (p < 0.05). The following significant changes in outcome measures were indicated at t(1) compared with t(0) and control group (p < 0.001): an increase in lumbar flexion and extension (mean difference = 9.26◦ (+54%) for flexion and 5.95◦ for extension(+98%)); reduction in VAS score (mean difference = 2.32 (+58%)) and RMQ score (mean difference = 4.9 (−34%)). All changes remained significant at t(fu). At t(0), lumbar flexion was correlated with extension (r = 0.547) and VAS (r = −0.581),whereas the RMQ score correlated with VAS score (r = 0.599) and negatively with lumbar extension (r = −0.665). At t(1),lumbar flexion correlated with extension (r = 0.664) and negatively with RMQ score (r = −0.54). At t(fu), changes in VAS score were negatively correlated with changes in lumbar flexion (r = −0.522), while changes in lumbar flexion correlated with extension (r = 0.58). A functional program of NWB group exercising improves functional, painful status, lumbar flexion and extension ranges of motion in women suffering from NSCLBP.

J Strength Cond Res 31(12): 3497-3502, 2017-The aim of the study was to evaluate the influence of a single partial-body cryotherapy (PBC) session on the maximum handgrip strength (JAMAR Hydraulic Hand dynamometer). Two hundred healthy adults were randomized into a PBC group and a control group (50 men and 50 women in each group). After the initial handgrip strength test (T0), the experimental group performed a 150-second session of PBC (temperature range between -130 and -160° C), whereas the control group stayed in a thermo neutral room (22.0 ± 0.5° C). Immediately after, both groups performed another handgrip strength test (T1). Data underlined that both groups showed an increase in handgrip strength values, especially the experimental group (Control: T0 = 39.48 kg, T1 = 40.01 kg; PBC: T0 = 39.61 kg, T1 = 41.34 kg). The analysis also reported a statistical effect related to gender (F = 491.99, P ≤ 0.05), with women showing lower handgrip strength values compared with men (women = 30.43 kg, men = 52.27 kg). Findings provide the first evidence that a single session of PBC leads to the improvement of muscle strength in healthy people. The results of the study imply that PBC could be performed also before a training session or a sport competition, to increase hand isometric strength.

The effective treatment of diabetes and the prevention of diabetic complications may be improved by a better understanding of the antioxidant function of intracellular defences against oxidative stress. Polymorphisms in antioxidant genes may determine cellular oxidative stress levels as a primary pathogenic role in diabetes and/or in its complications. SOD-2 was investigated in patients with type 1 diabetes mellitus (T1DM) to ascertain if specific genotypes have any protective influences in the pathogenic mechanisms in diabetes and/or in several different complications, including retinopathy, nephropathy and diabetic controls compared to normal healthy controls. 278 (136M:142F) T1DM patients and 135 (72M:63F) normal, healthy controls were investigated for SOD-2 polymorphism in the mitochondrial targeting sequence with Ala/Val (C-9T) substitution. A significant difference in the C-9-T genotype was observed between patients and normal controls but not between diabetic controls and patients with complications. There were significantly more of the diabetic control (DC, n=62) group (11.3%) than the patients with diabetic nephropathy (DN, n=73) (1.4%) with the CC genotype (p=0.03 and χ(2)=4.27, OR=9.16 (1.08

Type 1 Diabetes Modifies Brain Activation in Young Patients While Performing Visuospatial Working Memory Tasks

2015-01-01

In recent years, increasing attention has been paid to the effects of Type 1 Diabetes (T1D) on cognitive functions. T1D onset usually occurs during childhood, so it is possible that the brain could be affected during neurodevelopment. We selected young patients of normal intelligence with T1D onset during neurodevelopment, no complications from diabetes, and adequate glycemic control. The purpose of this study was to compare the neural BOLD activation pattern in a group of patients with T1D versus healthy control subjects while performing a visuospatial working memory task. Sixteen patients and 16 matched healthy control subjects participated. There was no significant statistical difference in behavioral performance between the groups, but, in accordance with our hypothesis, results showed distinct brain activation patterns. Control subjects presented the expected activations related to the task, whereas the patients had greater activation in the prefrontal inferior cortex, basal ganglia, posterior cerebellum, and substantia nigra. These different patterns could be due to compensation mechanisms that allow them to maintain a behavioral performance similar to that of control subjects. PMID:26266268

Increasing evidence demonstrates an association between diabetes and hippocampal neuron damage. This study aimed to determine the effects of troxerutin on cognitive deficits and glutamate cysteine ligase subunits (GCLM and GCLC) in the hippocampus of streptozotocin-induced type 1 diabetes mellitus (T1DM) rats. At 12weeks after streptozotocin injection, T1DM rats were randomly divided into 4 groups (n=15 each group) to receive no treatment (T1DM), saline (T1DM+saline), alpha-lipoic acid (T1DM+alpha-lipoic acid), and troxerutin (T1DM+troxerutin), respectively, for 6weeks. Meanwhile, 10 control animals (NC group) were assessed in parallel. Learning performance was evaluated by the Morris water maze. After treatment, hippocampi were collected for pathological examination by hematoxylin and eosin (H&E) staining. Next, hippocampal superoxide dismutase (SOD) activity, and malondialdehyde (MDA) and glutathione (GSH) levels were assessed. Finally, glutamate cysteine ligase catalytic (GCLC) and glutamate cysteine ligase modifier (GCLM) subunit mRNA and protein levels were quantified by reverse transcription polymerase chain reaction (RT-PCR) and Western blot, respectively. Compared with T1DM and T1DM+saline groups, escape latency was overtly reduced in T1DM+alpha-lipoic acid and T1DM+troxerutin groups. Significantly increased GCLM and GCLC mRNA levels, GCLC protein amounts, SOD activity, and GSH levels, and reduced MDA amounts were observed in T1DM+alpha-lipoic acid and T1DM+troxerutin groups. In T1DM and T1DM+saline groups, H&E staining showed less pyramidal cells in the hippocampus, with disorganized layers, karyopyknosis, decreased endochylema, and cavitation, effects relieved in T1DM+alpha-lipoic acid and T1DM+troxerutin groups. Troxerutin alleviates oxidative stress and promotes learning in streptozotocin-induced T1DM rats, a process involving GCLC expression. Copyright © 2016 Elsevier B.V. All rights reserved.

Chromium is an essential mineral that contributes to normal glucose function and lipid metabolism. This study evaluated the effect of chromium picolinate (CrPic) supplementation in patients with type 2 diabetes mellitus (T2DM). A four month controlled, single blind, randomized trial was performed with 71 patients with poorly controlled (hemoglobin A1c [HbA1c]>7%) T2DM divided into 2 groups: Control (n=39, using placebo), and supplemented (n=32, using 600μg/day CrPic). All patients received nutritional guidance according to the American Diabetes Association (ADA), and kept using prescribed medications. Fasting and postprandial glucose, HbA1c, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides and serum ferritin were evaluated. CrPic supplementation significantly reduced the fasting glucose concentration (-31.0mg/dL supplemented group; -14.0mg/dL control group; p<0.05, post- vs. pre-treatment, in each group) and postprandial glucose concentration (-37.0mg/dL in the supplemented group; -11.5 mg/dL in the control group; p<0.05). HbA1c values were also significantly reduced in both groups (p<0.001, comparing post- vs. pre-treatment groups). Post-treatment HbA1c values in supplemented patients were significantly lower than those of control patients. HbA1c lowering in the supplemented group (-1.90), and in the control group (-1.00), was also significant, comparing pre- and post-treatment values, for each group (p<0.001 and p<0.05, respectively). CrPic increased serum chromium concentrations (p<0.001), when comparing the supplemented group before and after supplementation. No significant difference in lipid profile was observed in the supplemented group; however, total cholesterol, HDL-c and LDL-c were significantly lowered, comparing pre- and post-treatment period, in the control group (p<0.05). CrPic supplementation had a beneficial effect on glycemic control in patients with poorly controlled T2DM, without affecting the lipid profile. Additional studies are necessary to investigate the effect of long-term CrPic supplementation. Copyright © 2015 Elsevier GmbH. All rights reserved.

Objectives: To evaluate the effectiveness of pre-surgical nasoalveolar molding (PNAM) in patients with unilateral cleft lip nasal deformities. Methods: This was a retrospective study involving 29 patients with unilateral cleft lip and palate defects, of whom 13 were treated with palatal devices with nasal stents (PNAM group) and 16 were treated with palatal devices without nasal stents or surgical tapes (control group). Submental oblique photographs and orthodontic models were longitudinally obtained at the initial visit (T1) and immediately before (T2) and after cheiloplasty (T3). Asymmetry of the external nose, degree of columellar shifting, nasal tip/ala nose ratio, nasal base angle, interalveolar gap, and the sagittal difference in the alveolar gap were measured. The study was conducted in the Orthodontic Clinic at Tokushima University Hospital, Tokushima, Japan between 1997 and 2012. Results: At T1, there were no significant intergroup differences in the first 4 asymmetry parameters. At T2, the PNAM group showed a significant improvement in all values compared to the control group. At T3, the PNAM group showed significant improvement in nasal asymmetry and columellar shifting. Model analysis showed significantly greater changes in the inter-alveolar gap and the sagittal difference of the alveolar cleft gap from T1 to T2 in the PNAM group. Conclusion: The use of PNAM is indispensable for pre-surgical orthodontic treatment at the early postnatal age. PMID:29436566

To evaluate the effectiveness of pre-surgical nasoalveolar molding (PNAM) in patients with unilateral cleft lip nasal deformities. Methods: This was a retrospective study involving 29 patients with unilateral cleft lip and palate defects, of whom 13 were treated with palatal devices with nasal stents (PNAM group) and 16 were treated with palatal devices without nasal stents or surgical tapes (control group). Submental oblique photographs and orthodontic models were longitudinally obtained at the initial visit (T1) and immediately before (T2) and  after cheiloplasty (T3). Asymmetry of the external nose, degree of columellar shifting, nasal tip/ala nose ratio, nasal base angle, interalveolar gap, and the sagittal difference in the alveolar gap were measured. The study was conducted in the Orthodontic Clinic at Tokushima University Hospital, Tokushima, Japan between 1997 and 2012. Results: At T1, there were no significant intergroup differences in the first 4 asymmetry parameters. At T2, the PNAM group showed a significant improvement in all values compared to the control group. At T3, the PNAM group showed significant improvement in nasal asymmetry and columellar shifting. Model analysis showed significantly greater changes in the inter-alveolar gap and the sagittal difference of the alveolar cleft gap from T1 to T2 in the PNAM group. Conclusion: The use of PNAM is indispensable for pre-surgical orthodontic treatment at the early postnatal age.

The efficacy of the nematode-trapping fungus Duddingtonia flagrans incorporated into an energy block was evaluated for the control of gastrointestinal nematodes in sheep. Four naturally parasitised sheep with average nematode egg counts of 2,470 eggs per gram grazed by pairs on two similar parasite-free paddocks for 30 days. During that period, one pair of sheep (treated animals, T1) received an energy block containing chlamydospores of D. flagrans at a dose of 200,000 chlamydopores/kg bw/day, while the second pair (control animals, C1) received a fungus-free energy block. The animals in both groups were taken off the paddocks after contaminating the pastures for a month with either nematode eggs plus fungal chlamydospores (T1) or nematode eggs alone (C1). Twelve parasite-free sheep were divided into two groups of six animals each, the treated group (T2) was placed on the paddock previously contaminated with parasites and fungus, while the control group (C2) was placed on the parasite-only paddock. These two groups grazed on their respective paddocks during 30 days and were then housed for 15 days, after which period they were slaughtered in order to determine the parasite burden present in each animal. Results showed that animals in group T2 harboured significantly less nematodes than their counterpart in group C2. The efficacy of D. flagrans was 92% against the total parasite burden, 100% against Haemonchus contortus and Teladorsagia circumcincta, 89.9% against Trichostrongylus colubriformis, 87.5% against Cooperia onchopora, and 90% against Trichostrongylus axei. No efficacy was detected against Nematodirus spathiger, Trichuris ovis and T. skrjabini.

This study analyzed the contribution of neuronal nitric oxide synthase (nNOS) to the hemodynamic manifestations of hyperthyroidism. The effects on hyperthyroid rats of the chronic administration of 7-nitroindazole (7-NI), an inhibitor of nNOS, were studied. Six groups of male Wistar rats were used: control, 7-NI (30 mg.kg-1.day-1 by gavage), T(4)50, T(4)75 (50 or 75 microg thyroxine.rat-1.day-1, respectively), T(4)50+7-NI, and T(4)75+7-NI. All treatments were maintained for 4 wk. Body weight, tail systolic blood pressure (SBP), and heart rate (HR) were recorded weekly. Finally, SBP, pulse pressure (PP), and HR were measured in conscious rats, and morphological, metabolic, plasma, and renal variables were determined. Expression of nNOS in the hypothalamus of T(4)75 and control rats was analyzed by Western blot analysis. The response of mean arterial pressure (MAP) to pentolinium (10 mg/kg iv) was used to evaluate the sympathetic contribution to BP in T(4)75 and T(4)75+7-NI rats. T(4) produced an increased hypothalamic nNOS expression and dose-related increases in blood pressure (BP), HR, and PP vs. control rats. 7-NI did not modify BP or any other hemodynamic variable in normal rats. However, 7-NI produced a marked reduction in BP, HR, PP, and food and water intake in both hyperthyroid groups and improved creatinine clearance in the T(4)75 group. Pentolinium produced a greater MAP decrease in the T(4)75+7-NI than in the T(4)75 group. In conclusion, administration of 7-NI attenuates the hemodynamic and metabolic manifestations of hyperthyroidism, suggesting that nNOS contributes to the hyperdynamic circulation of this endocrine disease by modulating sympathetic activity.

The aim of this study was to investigate the surface electromyographic (sEMG) activity of neck, trunk, and masticatory muscles in subjects with temporomandibular joint (TMJ) internal derangement treated with anterior mandibular repositioning splints. sEMG activities of the muscles in 34 adult subjects (22 females and 12 males; mean age 30.4 years) with TMJ internal derangement were compared with a control group of 34 untreated adults (20 females and 14 males; mean age 31.8 years). sEMG activities of seven muscles (anterior and posterior temporalis, masseter, posterior cervicals, sternocleidomastoid, and upper and lower trapezius) were studied bilaterally, with the mandible in the rest position and during maximal voluntary clenching (MVC), at the beginning of therapy (T0) and after 10 weeks of treatment (T1). Paired and Student's t-tests were undertaken to determine differences between the T0 and T1 data and in sEMG activity between the study and control groups. At T0, paired masseter, sternocleidomastoid, and cervical muscles, in addition to the left anterior temporal and right lower trapezius, showed significantly greater sEMG activity (P = 0.0001; P = 0.0001; for left cervical, P = 0.03; for right cervical, P = 0.0001; P = 0.006 and P = 0.007 muscles, respectively) compared with the control group. This decreased over the remaining study period, such that after treatment, sEMG activity revealed no statistically significant difference when compared with the control group. During MVC at T0, paired masseter and anterior and posterior temporalis muscles showed significantly lower sEMG activity (P = 0.03; P = 0.005 and P = 0.04, respectively) compared with the control group. In contrast, at T1 sEMG activity significantly increased (P = 0.02; P = 0.004 and P = 0.04, respectively), but no difference was observed in relation to the control group. Splint therapy in subjects with internal disk derangement seems to affect sEMG activity of the masticatory, neck, and trunk muscles.

This phase II clinical trial was conducted to compare the immunogenicity and safety of a newly developed tetanus-reduced diphtheria (Td) vaccine (GC1107-T5.0 and GC1107-T7.5) and control vaccine. This study was also performed to select the proper dose of tetanus toxoid in the new Td vaccines. Healthy adolescents aged between 11 and 12 yr participated in this study. A total of 130 subjects (44 GC1107-T5.0, 42 GC1107-T7.5 and 44 control vaccine) completed a single dose of vaccination. Blood samples were collected from the subjects before and 4 weeks after the vaccination. In this study, all subjects (100%) in both GC1107-T5.0 and GC1107-T7.5 groups showed seroprotective antibody levels (≥ 0.1 U/mL) against diphtheria or tetanus toxoids. After the vaccination, the geometric mean titer (GMT) against diphtheria was significantly higher in Group GC1107-T5.0 (6.53) and GC1107-T7.5 (6.11) than in the control group (3.96). The GMT against tetanus was 18.6 in Group GC1107-T5.0, 19.94 in GC1107-T7.5 and 19.01 in the control group after the vaccination. In this study, the rates of local adverse reactions were 67.3% and 59.1% in GC1107-T5.0 and GC1107-7.5, respectively. No significant differences in the number of adverse reactions, prevalence and degree of severity of the solicited and unsolicited adverse reactions were observed among the three groups. Thus, both newly developed Td vaccines appear to be safe and show good immunogenicity. GC1107-T5.0, which contains relatively small amounts of tetanus toxoid, has been selected for a phase III clinical trial. PMID:23579367

In contrast to type 2 diabetes, the association of body mass index (BMI) with glycemic control in type 1 diabetes (T1D) remains unclear. We investigated the relationship between BMI and average HbA 1c levels in subjects with T1D. In this multi-centre observational study, we analysed 719 subjects with T1D aged ≥18 years. Average HbA 1c levels over 18 months and other clinical and laboratory parameters were evaluated. The mean age and duration of diabetes at baseline were 41.5 ± 13.9 and 11.3 ± 8.7 years, respectively. A U-shaped correlation between BMI and 18-month average HbA 1c levels was documented by a spline curve. Based on this finding, subjects were divided into three groups according to BMI (group I, <21; group II, 21-23; and group III, ≥23 kg/m 2 ). In group I, the BMI negatively correlated with average HbA 1c (r = -0.172, p = 0.011), while a positive relationship was observed (r = 0.162, p = 0.012) in group III. Average HbA 1c levels were lower and the proportion of individuals with well-controlled glycemia (HbA 1c <7%) were increased in the higher BMI tertile group among subjects with group I as well as in the lower BMI tertile group among subjects with group III BMI. After adjustment with additional covariates in the multiple regression model, these associations between BMI and HbA 1c levels according to the different BMI ranges remained significant. In Korean subjects with T1D, an inverse relationship of BMI with HbA 1c levels was observed in the low BMI group, while a positive correlation was shown in the high BMI group.

This study was conducted to evaluate the effect of medicinal plant by-products (MPB) supplementation to a total mixed ration (TMR) on growth, carcass characteristics and economic efficacy in the late fattening period of Hanwoo steers. Twenty seven steers (body weight [BW], 573±57 kg) were assigned to 3 treatment groups so that each treatment based on BW contained 9 animals. All groups received ad libitum TMR throughout the feeding trial until slaughter (from 24 to 30 months of age) and treatments were as follows: control, 1,000 g/kg TMR; treatment 1 (T1), 970 g/kg TMR and 30 g/kg MPB; treatment 2 (T2), 950 g/kg TMR and 50 g/kg MPB. Initial and final BW were not different among treatments. Resultant data were analyzed using general linear models of SAS. Average daily gain and feed efficiency were higher (p<0.05) for T1 than control, but there was no difference between control and T2. Plasma albumin showed low-, intermediate- and high-level (p<0.05) for control, T1 and T2, whereas non-esterified fatty acid was high-, intermediate- and high-level (p<0.05) for control, T1 and T2, respectively. Carcass weight, carcass rate, backfat thickness and rib eye muscle area were not affected by MPB supplementation, whereas quality and yield grades were highest (p<0.05) for T1 and T2, respectively. Daily feed costs were decreased by 0.5% and 0.8% and carcass prices were increased by 18.1% and 7.6% for T1 and T2 compared to control, resulting from substituting TMR with 30 and 50 g/kg MPB, respectively. In conclusion, the substituting TMR by 30 g/kg MPB may be a potential feed supplement approach to improve economic efficacy in the late fattening period of Hanwoo steers. PMID:26580440

The present work aimed at studying growth pattern and carcass traits in pearl grey guinea fowl fed on dietary Neem (Azadirachta indica) leaf powder (NLP) over a period of 12 weeks. Day old guinea fowl keets (n=120) were randomly assigned to four treatment groups, each with 3 replicates. The first treatment was designated as control (T0) in which no supplement was added to the feed, while in treatments T1, T2 and T3, NLP was provided as 1, 2 and 3 g per kg of feed, respectively. The results revealed a significant increase in body weight at 12 weeks; 1229.7 for T1, 1249.8 for T2, and 1266.2 g T3 compared to 1220.0 g for the control group (P<0.05). The results also showed that the supplementation of NLP significantly increased feed intake (P≤0.05) which might be due to the hypoglycaemic activity of Neem. A significant increase was also found in the feed conversion ratio (FCR) of the treated groups over the control, showing that feeding NLP to the treated groups has lowered their residual feed efficiency. The results of the study demonstrate the beneficial effects of supplementing NLP on body weight gain and dressed yield in the treated groups in guinea fowl. NLP is, therefore, suggested to be used as a feed supplement in guinea fowl for higher profitability.

This proof-of-concept study examined the haemodynamic performance as well as the coronary and visceral organ perfusion using a new short balloon for intra-aortic counterpulsation (IABP) in a swine model of myocardial ischaemia. Eighteen healthy pigs underwent 120-min ligation of the left anterior descending coronary artery followed by 6 h of reperfusion, and they were randomly assigned into 3 groups undergoing IABP implantation with a 35-ml short balloon (n = 6), a 40-ml short balloon (n = 6) or no IABP implantation (controls, n = 6). Haemodynamics, and visceral and coronary flows were measured at baseline (t0), at 2 h of ischaemia (t1) and every hour thereafter until 6 h of reperfusion (from tR1 to tR6), respectively. Mesenteric and renal flows increased significantly at tR1 only in the IABP groups (all, P < 0.001) and were significantly higher than controls throughout the reperfusion periods (P < 0.001). Coronary systolic and diastolic blood flows increased only at tR1 in the IABP groups (all, P < 0.001) but were higher than controls at tR1-tR6. The IABP was associated with enhanced haemodynamics compared with controls. No difference was detected using different balloon volumes (all, P > 0.05). The new short balloon significantly increased visceral flow, enhanced haemodynamics and improved coronary circulation during reperfusion following myocardial ischaemia in our experimental model. © The Author 2015.

This study compares NT proBNP and troponin T levels in umbilical cord arterial blood and postnatal echocardiographic findings for infants of gestational and pregestational diabetic mothers and macrosomic infants. Twenty-seven infants of pregestational diabetic mothers, 61 infants of gestational diabetic mothers and 37 macrosomic infants of nondiabetic mothers were prospectively enrolled in this study along with a control group of 58 healthy infants of mothers without any pregestational or gestational disorders as the control group. All enrollees were born after 34 weeks of gestation. For this study, umbilical cord blood was drawn during delivery to determine NT proBNP and troponin T levels. Echocardiography was performed 24-72 h after the delivery. Umbilical cord troponin T and NT proBNP levels were found to be higher in the diabetic and macrosomic groups than in the control group (all of them p < 0.001). NT proBNP levels were positively correlated with interventricular septum thickness in the pregestational and gestational infants of diabetic mothers groups (r = 0.564 and r = 0.560, respectively, p < 0.01). Both pregestational and gestational diabetic mothers were divided into two groups according to HbA1c levels in the third trimester as good (<6.1 %) and suboptimal (>6.1 %) metabolic control. In the good and suboptimal metabolic control diabetic groups, NT proBNP levels were also positively correlated with interventricular septum thickness (r = 0.536 and r = 0.576, respectively, p < 0.01). In the suboptimal metabolic control diabetic group, NT proBNP was only found to be positively correlated with the left ventricular mass index (r = 0.586, p < 0.01). While there was no correlation in the myocardial performance index between infants of diabetic mothers and the control group, the myocardial performance index of macrosomic infants was lower than that of the control group (p = 0.017). Cardiac biomarkers (NT proBNP and troponin T) were elevated in infants of diabetic mothers and macrosomic infants. While there was a positive correlation between NT proBNP levels and cardiac structure in infants of pregestational and gestational diabetic mothers, there was no relationship between NT proBNP levels and cardiac function.

High prevalence of vitamin D deficiency in adolescents with type 1 diabetes (T1DM) has been recorded but data focused on the relationship between vitamin D, glycemic control and body composition is limited in T1DM patients. The study was aimed to investigate vitamin D status in T1DM patients and its association with body composition (fat and lean body mass) and clinical data. The study group comprised of 100 adolescents (15.3±1.9 yrs; 54 girls), including 60 T1DM patients (15.1±1.9 yrs; 32 girls) and 40 controls (15.6±1.8 yrs; 20 girls) from Warsaw, Poland. Serum total 25-hydroxyvitamin D (25(OH)D) levels and iPTH were measured by an ECLIA (Roche Diagnostics). Glycosylated hemoglobin (% HbA1c), serum calcium and inorganic phosphorous, and the use of dietary supplements were also assessed. DXA (GE Prodigy) was used to assess lean body mass (LBM; g), fat mass (FM; g), FM/LBM ratio, and respective Z-scores. Mean 25(OH)D level of 15.3±7.0 ng/mL (range 4.2-37.7 ng/mL) in T1DM was not different from that observed in controls (17.9±9.3 ng/mL; range 6.3-40.4 ng/mL). Eighty-two percent of T1DM patients and 67% controls had 25(OH)D levels <20 ng/mL, among them 25% T1DM and 12.5% controls revealed values <10 ng/mL. 5% T1DM and 15% controls had 25(OH)D>30 ng/mL. 25% from T1DM and 22% from control groups declared to use vitamin D supplementation and had significantly higher 25(OH)D levels compared to non-users (22.6±7.6 vs. 12.8±4.8 ng/mL in the T1DM; 26.9±11.5 vs. 15.3±6.8 ng/mL in controls, respectively). In the T1DM, low 25(OH)D levels negatively correlated with HbA1c (r=-0.320, P=0.013) and with iPTH (r=-0.434, P=0.001). 25(OH)D levels correlated negatively with Z-scores for FM/LBM ratio (r=-0.324; P=0.012) and Z-scores for FM (r=-0.229; P=0.079) and positively with LBM Z-scores (r=0.300; P=0.020). Serum Ca, serum iPTH did not differ T1DM and control groups but serum P level was significantly higher in T1DM patients compared to controls (1.39±0.19 mmol/L vs. 1.18±0.18 mmol/L; P=0.001, respectively). In T1DM adolescents vitamin D deficiency coincided with poor glycemic control and disturbed body composition. 25(OH)D levels were positively related to muscle stores and negatively with fat stores. Therefore, to limit a risk of disease related clinical complications both disturbed body composition and vitamin D deficiency should be corrected by implementation of regular vitamin D supplementation and increased intake of vitamin D-rich foods, as well as increased outdoors activities.

Aim: An experiment was conducted to evaluate the effect of supplementing different levels of salts of organic acid in the laying hen’s diet on their production performance and egg quality parameters during a period of 16-week. Materials and Methods: A total of 140 white leghorn laying hens at 24 weeks of age were randomly distributed to seven dietary treatment groups, i.e. T1 (control), T2 (0.5% sodium-butyrate), T3 (1.0% sodium-butyrate), T4 (1.5% sodium-butyrate), T5 (0.5% calcium-propionate), T6 (1.0% calcium-propionate) and T7 (1.5% calcium-propionate) consisting of 5 replications of 4 birds each in each treatment and housed in individual cages from 24 to 40 weeks of age. Feed intake, percent hen-day egg production, egg weight, egg mass production, feed conversion ratio (FCR), and economics of supplementation of salts of organic acids in layers’ ration were evaluated. Results: The dietary supplementation of salts of organic acids did not significantly affect the feed intake (g/day/hen) and body weight gain (g). Different levels of supplementation significantly (p<0.05) improved production performance (percent hen-day egg production and egg mass production) as compared to control group. FCR in terms of feed intake (kg) per dozen eggs was lowest (1.83±0.05) in T4 and feed intake (kg) per kg egg mass was lowest (2.87±0.05) in T5 as comparison to control (T1) group. Salts of organic acids supplementation resulted in significant (p<0.05) improvement in FCR. Egg weight was significantly (p<0.05) increased at 0.5% level of salts of organic acids in the diet. The cumulative mean values of feed cost per dozen egg production were Rs. 44.14, 42.40, 42.85, 43.26, 42.57, 43.29 and 43.56 in treatment groups T1, T2, T3, T4, T5, T6 and T7, respectively, and reduction in feed cost per kg egg mass production for Rs. 0.52 and 0.99 in groups T2 and T5, respectively, in comparison to T1 group. Conclusions: It can be concluded that supplementation of salts of organic acids may improve persistency of lay, egg weight, and FCR. From economical point of view, egg production was more profitable at 0.5% level of sodium butyrate and 0.5% level of calcium propionate which reduced the feed cost per dozen eggs and per kg egg mass production without affecting the egg quality.

Objective The main objective of this study was to determine the effect of different diets for early-weaned (EW) calves on rumen development, and how this affects fat deposition in the longissimus dorsi of adult Korean Hanwoo beef cattle. Methods Three EW groups were established (each n = 12) in which two- week-old Hanwoo calves were fed for ten weeks with milk replacer+concentrate (T1), milk replacer+concentrate+ roughage (T2), or milk replacer+concentrate+30% starch (T3); a control group (n = 12) was weaned as normal. At six months, 5 calves of each group were slaughtered and their organs were assessed and rumen papillae growth rates were measured. The remaining calves (n = 7 in each group) were raised to 20 months for further analysis. Results Twenty-month-old EW calves had a higher body weight (BW), backfat thickness (BF), longissimus dorsi muscle area (LMA) and intramuscular fat (IMF) than the control (p<0.05). Organ growth, rumen histology, and gene expression patterns in the 6-month-old calves were positively related to the development of marbling in the loin, as assessed by ultrasound analysis (p<0.05). In the group fed the starch-enriched diet (T3), higher BW, BF, LMA, and IMF were present. The IMF beef quality score of 20-month-old cattle was 1+ for the T2 and T3 diets and 1 for the T1 diet (p<0.05). Conclusion Papillae development was significantly greater in calves fed on high-concentrate diets and this may have resulted in the improved beef quality in the EW dietary groups compared to the control.

The Haematotoxic implications of exposure to petroleum fumes through inhalation in human subjects were investigated. A total of 400 subjects (200 males and 200 females) aged between 18-30 years participated. Each gender was further categorized into two groups of 100 each for control and test, respectively. The test group was again subdivided into test 1 (T1) and test 2 (T2) in both sexes. T1 subjects were exposed to petroleum fumes for two years and below while T2 subjects were exposed for more than two years. Samples of blood were collected daily and subjected to haematological analysis. The results obtained showed that in males and females, red blood cell counts (10(6) /mm3) was significantly [P < 0.001] decreased in T1 (4.4 +/- 0.13) and T2 (3.85 +/- 0.07) compared to control (4.76 +/- 0.01). White blood cell counts, haematocrit, haemoglobin concentration and mean corpusclular haemoglobin concentration (MCHC) were significantly [P < 0.01] decreased in both sexes of test groups when compared with control. There was also a significant [P < 0.001] decrease in mean corpuscular haemoglobin (MCH) and mean corpuscular volume (MCV) in test 2 males compared with control. Most subjects exposed for longer than two years (T2) had significantly [P < 0.001] lower values of red blood cell count, haemoglobin concentration and haematocrit than those exposed for less than two years. The odds/odds ratio that a subject would become anaemic progressively rose from less than 1 in the control to greater than 1 or infinity on exposure to petroleum fumes. These results indicate that the petroleum fumes cause a reduction in haematological indices which worsens with prolonged exposure.

To study effects of 50 Hz 1.8 mT sinusoidal electromagnetic fields (SEMFs) on bone mineral density (BMD) in SD rats. Thirty SD rats weighted(110±10) and aged 1 month were randomly divided into control group and electromagnetic field group, 15 in each group. Normal control group of 50 Hz 0 mT density and sinusoidal electromagnetic field group of 50 Hz 1.8 mT were performed respectively with 1.5 h/d and weighted weight once a week, and observed food-intake. Rats were anesthesia by intraperitoneal injection and dual energy X-ray absorptiometry were used to detect bone density of whole body, and detected bone density of femur and vertebral body. Osteocalcin and tartrate-resistant acid phosphatase 5b were detected by ELSA; weighted liver, kidney and uterus to calculate purtenance index, then detected pathologic results by HE. Compared with control group, there was no significant change in weight every week, food-intake every day; no obvious change of bone density of whole body at 2 and 4 weeks, however bone density of whole body, bone density of excised femur and vertebra were increased at 6 weeks. Expression of OC was increased, and TRACP 5b expression was decreased. No change of HE has been observed in liver, kidney and uterus and organic index. 50 Hz 1.8 mT sinusoidal electromagnetic fields could improve bone formation to decrease relevant factors of bone absorbs, to improve peak bone density of young rats, in further provide a basis for clinical research electromagnetic fields preventing osteoporosis foundation.

Dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEAS) are anabolic prehormones involved in the synthesis of testosterone. Both have been shown to exert neuroprotective effects during stress. In this randomized, controlled, double-blind field study, we examined the effects of a 12-day DHEA regimen on stress indices in military men undergoing survival training. Forty-eight men were randomized to either a DHEA treatment group or placebo control group. The treatment group received 50 mg of oral DHEA supplementation daily for 5 days during classroom training followed by 7 days of 75 mg during stressful field operations. Control subjects received identical placebo pills. Salivary assays (DHEA[S], testosterone, and cortisol) were conducted at four time points: distal pre-stress (T1), proximal pre-stress (T2), mock-captivity stress (T3), and 24 h recovery (T4). Subjective distress was also assessed at T1, T3, and T4. As expected, DHEA treatment resulted in higher salivary concentrations of DHEA and DHEAS during daily living, mock-captivity stress, and recovery. Similar patterns were observed for salivary markers of anabolic balance: DHEA/cortisol, DHEAS/cortisol, and testosterone/cortisol concentration ratios. Despite notable time effects, no group differences emerged for subjective distress. A brief, low dose DHEA regimen yielded large increases in salivary DHEA(S) concentrations and enhanced anabolic balance throughout sustained military stress. These physiological changes did not extrapolate to subjective distress.

In this study, we aimed to compare the serum lipid profile and fatty acid (FA) compositions of erythrocyte membrane (EM) and plasma in three different patient groups (group 1: type 2 diabetes mellitus (T2DM)+end-stage renal disease (ESRD), group 2: ESRD, group 4: T2DM) and healthy controls (group 3) simultaneously. 40 ESRD patients treated with hemodialysis (HD) in Gulhane School of Medicine (20 with T2DM) and 32 controls (17 with T2DM, 15 healthy controls) were included in the study. Plasma and EM FA concentrations were measured by gas chromatography-flame ionization detector (GC-FID). Plasma and EM palmitic acid (PA) and stearic acid (SA) levels were significantly higher in T2DM patients compared to controls (p=0.040 and p=0.002 for plasma, p=0.001 and p=0.010 for EM, respectively). EM docosahexaenoic acid (DHA) levels were also significantly lower in patients with ESRD+T2DM and ESRD compared to controls (p=0.004 and p=0.037, respectively). Patients with insulin resistance display a pattern of high long chain saturated FAs (PA, SA and arachidic acids). However, while there are no recognized standards for normal EM DHA content, decreased levels of EM DHA in ESRD patient groups (groups 1 and 2) suggest that there may be reduced endogenous synthesis of DHA in HD subjects, due to the decreased functionality of desaturase and elongase enzymes. Because membrane PUFA content affects membrane fluidity and cell signaling, these findings are worthy of further investigation. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

The management of breakthrough pain in cancer patients is always a challenge for medical professions. Occurring in 80% of cancer patients with advanced disease, breakthrough pain significantly decreases both patient's and caregiver's quality of life. The aim of this study is to assess the analgesic efficacy of a fixed inhaled nitrous oxide/oxygen mixture for adult cancer patients with breakthrough pain. This is a randomized, placebo-controlled, double-blind study; it will be conducted in the General Hospital of Ningxia Medical University. The target study subjects are at least 18 years old, and are hospitalized cancer patients who are receiving routine opioids to control cancer-related pain but still experience breakthrough pain. A total of 240 patients will be recruited and randomly allocated between three treatment groups (A, B, C) and a control group (group D) in a ratio of 3:1. All treatment groups (A, B, C) will receive standard pain treatment (oral immediate-release morphine) plus a pre-prepared nitrous oxide/oxygen mixture, and the control group (D) will receive the standard pain treatment plus oxygen. Patients, doctors, nurses, and data collectors are all blind to the experiment. Assessments will be taken before treatment (T0), at 5 min (T1) and 15 min (T2) during treatment, and at 5 min after treatment (T3). The primary endpoint measures will be the percentage of patients whose pain is relieved at T1, T2, and T3. Secondary outcome measures will include the safety of treatment, adverse events, and satisfaction from both health professionals and patients. This study aims to provide an effective and practical intervention for a fast breakthrough pain relief and to improve cancer patients' quality of life significantly. The Evidence-Based Medicine Working Group claim that a randomized, double-blind, placebo-controlled experimental intervention is the most appropriate design to demonstrate its efficacy, so this study could give a new approach to controlling breakthrough pain episodes.

Cerebral palsy (CP) and Duchenne muscular dystrophy (DMD) are neuromuscular disorders characterized by muscle weakness. Weakness in CP has neural and non-neural components, whereas in DMD, weakness can be considered as a predominantly non-neural problem. Despite the different underlying causes, weakness is a constraint for the central nervous system when controlling gait. CP demonstrates decreased complexity of motor control during gait from muscle synergy analysis, which is reflected by a higher total variance accounted for by one synergy (tVAF1). However, it remains unclear if weakness directly contributes to higher tVAF1 in CP, or whether altered tVAF1 reflects mainly neural impairments. If muscle weakness directly contributes to higher tVAF1, then tVAF1 should also be increased in DMD. To examine the etiology of increased tVAF1, muscle activity data of gluteus medius, rectus femoris, medial hamstrings, medial gastrocnemius, and tibialis anterior were measured at self-selected walking speed, and strength data from knee extensors, knee flexors, dorsiflexors and plantar flexors, were analyzed in 15 children with CP [median (IQR) age: 8.9 (2.2)], 15 boys with DMD [8.7 (3.1)], and 15 typical developing (TD) children [8.6 (2.7)]. We computed tVAF1 from 10 concatenated steps with non-negative matrix factorization, and compared tVAF1 between the three groups with a Mann-Whiney U-test. Spearman's rank correlation coefficients were used to determine if weakness in specific muscle groups contributed to altered tVAF1. No significant differences in tVAF1 were found between DMD [tVAF1: 0.60 (0.07)] and TD children [0.65 (0.07)], while tVAF1 was significantly higher in CP [(0.74 (0.09)] than in the other groups (both p < 0.005). In CP, weakness in the plantar flexors was related to higher tVAF1 (r = −0.72). In DMD, knee extensor weakness related to increased tVAF1 (r = −0.50). These results suggest that the non-neural weakness in DMD had limited influence on complexity of motor control during gait and that the higher tVAF1 in children with CP is mainly related to neural impairments caused by the brain lesion.

This study aimed to test the beneficial effect of grape seed extract (GSE) (Vitis vinifera) and Vitamin C in oxidative stress and reperfusion injury induced by cardiopulmonary bypass (CPB) in coronary artery bypass surgery. In this randomized trial, 87 patients undergoing elective and isolated coronary bypass surgery included. The patients were randomly assigned into three groups (n = 29 each): (1) Control group with no treatment, (2) GSE group who received the extract 24 h before operation, 100 mg every 6 h, orally, (3) Vitamin C group who received 25 mg/kg Vitamin C through CPB during surgery. Blood samples were taken from coronary sinus at (T1) just before aortic cross clamp; (T2) just before starting controlled aortic root reperfusion; and (T3) 10 min after root reperfusion. Some clinical parameters and biochemical markers were compared among the groups. There were significant differences in tracheal intubation times, sinus rhythm return, and left ventricular function between treatment groups compared with control (P < 0.05). Total antioxidant capacity was higher (P < 0.05) in both grape seed and Vitamin C groups at T2 and T3 times. In reperfusion period, malondialdehyde level was increased in control group; however, it was significantly lower for the grape seed group (P = 0.04). The differences in the mean levels of superoxide dismutase and glutathione peroxidase among the three groups were not significant (P > 0.05 in all cases). In our patients, GSE and Vitamin C had antioxidative effects and reduced deleterious effects of CPB during coronary artery bypass grafting surgery.

Oxidative stress plays an important role in the pathogenesis of type 1 diabetes mellitus (T1DM). To evaluate the association of glutathione S-transferase mu 1 (GST M1) and glutathione S-transferase theta 1 (GST T1) polymorphisms with development of T1DM and disease-related risk factors. Measurement of fasting glucose, serum creatinine, lipid profile, and glycosylated hemoglobin (HbA1c), as well as evaluation of GST T1 and M1 genetic polymorphisms using polymerase chain reaction were done in 64 diabetic children and 41 controls. The diabetic group had significantly higher fasting glucose, HbA1c, and cholesterol levels. GST T1 null genotype was more frequent in the diabetic than the control group with 4.2-fold increased risk of T1DM (odds ratio=4.2; 95% confidence interval=1.6-11.5; p=0.03). Significant positive associations were found with lipid profile, HbA1c, and duration of illness but not with age, age at onset, and body mass index. Gene polymorphisms of the enzyme GST are associated with development of T1DM and disease-related risk factors.

In clinical practice, translating the benefits of a sustained physically active lifestyle on glycaemic control in patients with type 2 diabetes mellitus (T2DM) is difficult. A walking prescription may be an effective alternative. To examine the effect of a 10 000 steps per day prescription on glycaemic control of patients with T2DM. Forty-six adults with T2DM attending a general outpatient clinic were randomised into two equal groups. The intervention group was given goals to accumulate 10 000 steps per day for 10 weeks, whereas the control group maintained their normal activity habits. Daily step count was measured with waist-mounted pedometer and baseline and endline average steps per day. Glycosylated haemoglobin (HbA1c), anthropometric, and cardiovascular measurements were also obtained. An intention-to-treat analysis was done. The average baseline step count was 4505 steps per day for all participants, and the average step count in the intervention group for the last 4 weeks of the study period was higher by 2913 steps per day (95% confidence interval [CI] = 1274 to 4551, F (2, 37.7) = 18.90, P <0.001). Only 6.1% of the intervention group participants achieved the 10 000 steps per day goal. The mean baseline HbA1c was 6.6% (range = 5.3 to 9.0). Endline HbA1c was lower in the intervention group than in the control group (mean difference -0.74%, 95% CI = -1.32 to -0.02, F = 12.92, P = 0.015) after adjusting for baseline HbA1c. There was no change in anthropometric and cardiovascular indices. Adherence to 10 000 steps per day prescription is low but may still be associated with improved glycaemic control in T2DM. Motivational strategies for better adherence would improve glycaemic control. © British Journal of General Practice 2018.

There are contrasting results obtained in migraineurs concerning the levels and the role of both pro-inflammatory and anti-inflammatory cytokines. In this study, the association of the occurrence and clinical characteristics of migraine with the polymorphisms of tumor necrosis factor alpha (TNF-alpha) -308 G/A (rs1800629), interleukin-1alpha (IL-1alpha) +4845 G/T (rs17561), IL-1beta+3953 C/T (rs1143634) and interleukin-1 receptor antagonist variable number tandem repeat (IL-1RA VNTR) genes were studied. We also investigated the genetic linkage between these genes. Sixty-seven patients with migraine without aura (MwoA) and 96 unrelated, age- and sex-matched migraine-free, healthy control subjects from the same geographic area were investigated. We observed significant differences in the genotypic distribution of the TNF-alpha-308 G/A and IL-1beta+3953 C/T polymorphism for migraineurs compared with controls (P = 0.004). Frequency of the TNF-alpha-308 GG genotype was higher in the control group than MwoA group (82.1% vs 55.2%). Differences in the distribution of the allele frequencies were also observed, being the TNF-alpha-308 G allele overrepresented in control group and TNF-alpha-308 A allele in MwoA group. In addition, there was a significant increase of the IL-1beta+3953 T allele in MwoA cases compared with controls (P = 0.004). In conclusion, the present results indicate the possible contribution of TNF-alpha and IL-1beta gene polymorphisms to migraine headache generation in MwoA patients.

We assessed the psychological profile of a large sample of patients with chronic daily headache (CDH) seen in tertiary care. We used a case-control design to study 791 patients who fell into the following categories: ARH group, chronic migraine with analgesic overuse (analgesic rebound headache, ARH), n=399; CM group, chronic migraine (CM) without analgesic overuse, n=158; and new daily persistent headache (NDPH) group, n=69. These groups were compared to two control groups: 1, migraine, n=100; 2, chronic posttraumatic headache (CPTH), n=65. We assessed personality and psychopathology with the Minnesota multiphasic personality inventory (MMPI)-2. The number of patients with Tscores > or =65 and < or =40 were analyzed by the two-sided Fischer's exact test. The ARH and CM groups had a higher number of subjects with T-scores > or =65, when compared to the migraine group, on the following scales: 1 (hypochondrias), 2 (depression), 8 (schizophrenia) and 0 (social introversion). No differences were observed between the NDPH and migraine groups. Considering CPTH as the control group, the pattern we found was quite the opposite of that described above: NDPH group presented a higher number of subjects with T-scores > or =65 on the following scales: 1, 2, 7 (psychasthenia) and 8. ARH and CM groups had significantly higher T-scores for scale 7 alone. NDPH showed T-scores < or =40 in scale 9 when compared to both control groups. We conclude that: (1) psychopathological factors are common in CDH patients, and appear to be a consequence of the chronification process; (2) low scores on scale 9 (hypomania) may relate to the development of NDPH; (3) psychopathological profiles differ among the subgroups of CDH and the MMPI-2 is reliable in identifying such patterns; and (4) psychological assessment is an essential step in the evaluation and treatment of patients with CDH.

The efficacy of anthelmintic treatment at 1, 3, and 6 month intervals was evaluated in a prospective controlled field study with naturally exposed Lithuanian village dogs by monthly coproscopy during 1 year. A placebo-treated control group (C) (n = 202) and groups treated with two broad-spectrum anthelmintics, febantel/pyrantel-embonate/praziquantel (Drontal® Plus, Bayer) (D1, D3, D6; n = 113-117) and emodepside/praziquantel (Profender®, Bayer) (P1, P3, P6; n = 114-119), were included. At the beginning of the study, eggs of Toxocara canis (4.02%) and T. cati (0.44%) identified morphometrically and/or molecularly and eggs of taeniid- (0.78%) and Capillaria-like eggs (5.03%) were present in the feces without significant differences in prevalence between groups. Significant decreases in excretion of T. canis eggs was found 1 month after the treatment with Drontal® Plus in February (D1) and with Profender® in October (P1), November (P1), December (P3), February (P1), and March (P1, P3), as compared to controls in the same months. The incidence of egg excretion per dog at least once a year was significantly lower in group P1 for T. canis (4.24%; p < 0.01) and in groups D1, P1 for taeniid eggs (0%; p < 0.01 and p < 0.001), when compared to controls (16.96 and 6.70%, respectively). A critical analyses of factors possibly responsible for intestinal passage of canine helminth eggs revealed that chained dogs excreted T. canis eggs more frequently 1 month after treatment compared to dogs in pens, particularly from November to March (p = 0.01). The incidence of single detection of T. cati eggs was significantly increased in chained dogs (12.46%) as compared to fenced dogs (1.08%; p = 0.0001).

Osteoporosis is a multi factorial disease with dimension of genetic and nutritional considerations. The aim of this study was to present data from the association of plasma zinc, copper and toxic elements of lead and cadmium levels with bone mineral density in Iranian women. 135 women gave their information and enrolled. Fasting plasma was used for measurement of trace elements and heavy metals by Differential Pulse Anodic Stripping Voltammetry. Control group (n = 51) were normal in both lumbar spine (L1-L4) and femoral neck density (T-score ≥ -1), but just femoral neck T-score was considered as criterion in selection of patient group (n = 49, Tscore < -1). No differences were found in the nutritional status, number of diseases, drugs and functional activities between these groups. Plasma Zn, Cu, Pb, Cd levels were analyzed by, a method of voltammetry. Mean ± SD levels of copper and zinc was 1.168 ± 0.115, 1.097 ± 0.091 μg/ml in control group, 1.394 ± 0.133, 1.266 ± 0.11 μg/ml in total patient (TP) and 1.237 ± 0.182, 1.127 ± 0.176 μg/ml in Mild patients(-1 > T-score > -1.7), 1.463 ± 0.174, 1.327 ± 0.147 μg/ml in Severe patient group (T-score < -1.7); respectively. Mean ± SD plasma level of lead and cadmium was 168.42 ± 9.61 ng/l, 2.91 ± 0.18 ng/ml in control group, 176.13 ± 8.64 ng/l, 2.97 ± 0.21 ng/ml in TP, 176.43 ± 13.2 ng/l, 2.99 ± 0.1 ng/ml in mild patients, 221.44 ± 20 ng/l and 3.80 ± 0.70 ng/ml in severe patient group, respectively. In this study plasma zinc, copper, lead & cadmium concentrations were higher in the patients than in the control, though differences were not significant. However, differences were higher between the controls and patients with severe disease (T-score < -1.7). In addition adjusted T-score of femur with age and BMI showed negative significant correlation with plasma levels of zinc and lead in total participants (p < 0.05, r = -0.201, p = 0.044, r = -0.201). It seems that more extensive study with larger ample size might supply definite results about this association for copper and cadmium.

Diabetes Mellitus type 1 (T1DM) is a chronic disease that requires patients' self-monitoring and self-management to achieve glucose targets and prevent complications. Telenursing implicates technology in the interaction of a specialized nurse with patients with chronic diseases in order to provide personalized care and support. To evaluate the effect of telenursing on T1DM patients' compliance with glucose self-monitoring and glycemic control. Randomized controlled study. Outpatient Department of Diabetes, Endocrinology and Metabolism of a University Hospital in Northern Greece. Ninety-four T1DM patients were recruited and randomized in two groups by a random number generator. The intervention group (N = 48) was provided with telenursing services. A specialized nurse made a weekly contact via telephone motivating patients to frequently measure blood glucose and adopt a healthy lifestyle. The control group (N = 46) received standard diabetes advice and care in the clinic. The primary outcome was the effect of the intervention in glucose control and glucose variability. The secondary outcome was the effect on frequency of self-monitoring. SPSS 20.0 was used for data analysis. The two groups did not differ in age, sex, physical activity or initial HbA1c. In the intervention group, blood glucose significantly decreased at the end of the study in all predefined measurements, compared to control group: morning (93.18 ± 13.30 mg/dl vs. 105.17 ± 13.74 mg/dl, p < 0.005), pre-prandial (114.76 ± 9.54 mg/dl vs. 120.84 ± 4.05 mg/dl, p < 0.005), post-prandial (193.35 ± 25.36 mg/dl vs. 207.84 ± 18.80 mg/dl, p < 0.005), and HbA1c decreased significantly over time in the intervention group (8.3 ± 0.6% at the beginning of the study vs. 7.8 ± 1% at the end of the study, p = 0.03). In the intervention group there were also fewer omitted glucose measurements than in the control group. Patients in the intervention group achieved better glucose control and more frequent self-monitoring than patients in routine care in the clinic. The findings of our study indicate that telenursing can motivate T1DM patients to better control their disease. Copyright © 2018 Elsevier Ltd. All rights reserved.

To assess the ability of schoolchildren to use a automated external defibrillator (AED) to provide an effective shock and their retention of the skill 1 month after a training exercise supported by audiovisual materials. Quasi-experimental controlled study in 205 initially untrained schoolchildren aged 6 to 16 years old. SAEDs were used to apply shocks to manikins. The students took a baseline test (T0) of skill, and were then randomized to an experimental or control group in the first phase (T1). The experimental group watched a training video, and both groups were then retested. The children were tested in simulations again 1 month later (T2). A total of 196 students completed all 3 phases. Ninety-six (95.0%) of the secondary school students and 54 (56.8%) of the primary schoolchildren were able to explain what a SAED is. Twenty of the secondary school students (19.8%) and 8 of the primary schoolchildren (8.4%) said they knew how to use one. At T0, 78 participants (39.8%) were able to simulate an effective shock. At T1, 36 controls (34.9%) and 56 experimental-group children (60.2%) achieved an effective shock (P< .001). At T2, 53 controls (51.4%) and 61 experimental-group children (65.6%) gave effective shocks (P=.045). All the students completed the tests in 120 seconds. Their average times decreased with each test. The secondary school students achieved better results. Previously untrained secondary school students know what a AED is and half of them can manage to use one in simulations. Brief narrative, audiovisual instruction improves students' skill in managing a SAED and helps them retain what they learned for later use.

To evaluate the effects of quad-helix treatment on the eruption pattern of maxillary second molars in patients with maxillary incisor crowding. The lateral cephalograms of 40 consecutively treated patients in the early mixed-dentition group (treatment group) were examined in comparison with those of the same number of untreated patients with a similar form of malocclusion (control group). The cephalograms of the treated patients were taken at the start (T0) and at the end (T1) of treatment, and those of the untreated patients were also taken at about the same time as T0 and T1. The mean ages at T0 and T1 in the two groups were about the same. Distal tipping and movement and impeded extrusion of the maxillary first molars were notable in the treatment group compared with the control group. The actual treatment changes with the use of the quad-helix found expression in distal tipping and impeded vertical eruption of maxillary second molars. The more the maxillary first molars were tipped distally and the less the maxillary first molars extruded, the more the vertical eruption of the maxillary second molars was impeded. Quad-helix treatment gives rise to spontaneous distal tipping and impeded vertical eruption of the maxillary second molars.

A total of 360 1-d-old male commercial Arbor Acre broiler chickens were randomly assigned to 5 groups (6 replicates of 12 birds each) to evaluate the dietary effects of polysavone (0·5, 1·0 and 1·5 g/kg), a natural extract from alfalfa, and 0·15 g/kg chlortetracycline (CTC) on growth performance, antioxidation and meat quality of broiler chickens. 2. Over the 6-week study, feed intake increased significantly with CTC supplementation and final body weight (BW) was significantly higher for 1·0 g/kg polysavone and 0·15 g/kg CTC treatments. Feed:gain ratio was not significantly affected by the dietary treatments. 3. At 3 weeks of age, serum total superoxide dismutase (T-SOD) activity for all polysavone treatments was significantly higher than controls, liver T-SOD activity in 1·5 g/kg polysavone group was significantly higher than the control and CTC groups, and serum glutathione peroxidase (GSHPx) activity for 1·5 g/kg polysavone and liver GSHPx activity in all polysavone groups were significantly higher than CTC. 4. At 6 weeks of age, serum and liver T-SOD activity in 1·5 g/kg polysavone group and liver GSHPx activity for all polysavone treatments were higher significantly than the control and CTC groups, and serum malondialdehyde (MDA) content for all polysavone treatments was significantly lower than CTC. 5. Breast muscle T-SOD activity and pH value at 6 weeks of age were significantly higher and MDA content was significantly lower in 1·0 and 1·5 g/kg polysavone groups than in the control and CTC groups. Breast muscle shear force was significantly lower in l·5 g/kg polysavone group compared with the control, and drip loss for all polysavone treatments was significantly lower than CTC. 6. It was indicated that polysavone modulates antioxidation and modifies meat quality, but with no adverse effect on performance of broiler chickens, and that CTC can be beneficial to performance but has no beneficial effect on antioxidant function or meat quality.

The aim of this study was to investigate the short- and long-term effects induced by rapid maxillary expansion (RME) on the shape of the maxillary and circummaxillary structures by means of thin-plate spline (TPS) analysis. The sample consisted of 42 patients who were compared with a control sample of 20 subjects. The treated subjects underwent Haas-type RME, followed by fixed appliance therapy. Postero-anterior (PA) cephalograms were analysed for each treated subject at T1 (pre-treatment), T2 (immediate post-expansion), and T3 (long-term observation), and were available at T1 and T3 for the control group (CG). The mean age at T1 was 11 years and 10 months for both groups. The mean chronological ages at T3 were 20 years, 6 months for the treated group (TG) and 17 years, 8 months for the control group. The study focused on shape changes in the maxillary, nasal, zygomatic, and orbital regions. TPS analysis revealed significant shape changes in the TG. They consisted of an upward and lateral displacement of the two halves of the naso-maxillary complex as a result of active expansion in the short-term, and normalization of maxillary shape in the transverse dimension in the long-term (the initial transverse deficiency of the maxilla in the treated group was eliminated by RME therapy both in the short- and long-term). At the end of the observation period, the nasal cavities were larger when compared with both their pre-expansion configuration and the final configuration in the controls. RME with the Haas appliance appears to be an efficient therapeutic means to induce permanent favourable changes in the shape of the naso-maxillary complex.

To explore the changes of protein expression of mitochondrial fission gene dynamin-related 1(Drp 1) in the cortical neurons of rats with chronic fluorosis. A total of 120 one-month-old SD rats (each weighing approximately 100-120 g at the beginning of the experiment) were randomly divided into three groups, and fed with the different doses of fluoride containing in drinking water (untreated control containing 0 mg/L fluoride, and low-fluoride & high-fluoride supplemented with 10 and 50 mg/L fluoride,respectively). After 3 or 6 months exposure, 20 rats from each group were killed. Then the protein expression of mitochondrial fission gene, Drp1, was detected by immunohistochemistry and western-blotting method. Dental fluorosis and urinary fluorosis were obviously found in the rats exposed to fluoride. At the experiment period of 3 months, the numbers of positive cells of Drp1 detected by immunohistochemistry changed. Compared with the control group (36.3 ± 5.8), the changes in low-fluoride group (34.7 ± 4.1) showed no significant difference (t = 1.5, P > 0.05),but the increase in high-fluoride group (45.0 ± 4.7) had statistical significance (t = 8.8, P < 0.05). The western-blotting method had consistent results. Compared with the control group (0.59 ± 0.03), a significant increase of the average topical density in low- fluoride (0.62 ± 0.03) and high-fluoride (0.71 ± 0.02) groups were found (t = 0.02,0.11, P < 0.05). At the experiment period of 6 months, the numbers of positive cells of Drp1 detected by immunohistochemistry significantly changed. Compared with the control group (33.2 ± 4.4), the number in low- fluoride and high-fluoride groups were separately (36.6 ± 3.8) and (39.4 ± 4.2),both increased significantly (t = 3.5,6.3, P < 0.05). Same results could be found in western-blotting method,compared with the control group (0.65 ± 0.06), the average topical density in low- fluoride (0.80 ± 0.09) and high-fluoride (0.76 ± 0.08) groups both increased significantly (t = 0.1,0.1, P < 0.05). Taking excessive amount of fluoride might result in the changes of expression of Drp1, and the neurons damage from the chronic fluorosis might be associated with the hyperfunction of mitochondrial fusion.

This study examined the effects of a 12-week physical activity intervention on the motor skill proficiency and executive function of 22 boys (aged 9.08 ± 1.75 years) with autism spectrum disorder. In Phase I of the 12 weeks, 11 boys with autism spectrum disorder (Group A) received the intervention, whereas the other 11 boys with autism spectrum disorder (Group B) did not (true control, no intervention). The arrangement was reversed in Phase II, which lasted an additional 12 weeks. The Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, and the Wisconsin Card Sorting Test were conducted three times for each participant (Group A, primary grouping: baseline (T1), post-assessment (T2), and follow-up assessment (T3); Group B, control grouping: T1-T2; intervention condition, T2-T3). The main findings were that both groups of children with autism spectrum disorder significantly exhibited improvements in motor skill proficiency (the total motor composite and two motor-area composites) and executive function (three indices of the Wisconsin Card Sorting Test) after 12 weeks of physical activity intervention. In addition, the effectiveness appeared to have been sustained for at least 12 weeks in Group A. The findings provide supporting evidence that physical activity interventions involving table tennis training may be a viable therapeutic option for treating children with autism spectrum disorder.

To evaluate the protective effect of thalidomide, a potent anti-inflammatory drug, on the development of diabetic cardiomyopathy (DMCMP). We induced type 1 diabetes using streptozocin in 8-week-old Sprague-Dawley rats, divided them into two groups-a thalidomide treatment group (DM-T, n = 15) and a non-treatment group (DM-N, n = 15)-and compared them with a normal control (n = 10). Ten weeks after diabetes induction, heart and lung mass indices were higher in the DM-N group compared with the control group. In the DM-T group, increases in heart and lung mass indices were attenuated compared with the DM-N group. On echocardiographic examination, systolic and diastolic mitral annulus velocities were impaired in the DM-N group, but they remained normal in the DM-T group. On haemodynamic analyses, left ventricular (LV) systolic function, represented by end-systolic elastance (0.35 ± 0.14 vs. 0.18 ± 0.07 mmHg/μl, P < 0.001) and preload-recruitable stroke work (90.5 ± 24.3 vs. 51.8 ± 22.0 mmHg, P < 0.001), was preserved in the DM-T group compared with the DM-N group. Likewise, deterioration of LV diastolic function was attenuated in the DM-T group. Increases in serum levels of TNF-α were attenuated in the DM-T group compared with the DM-N group. On histological analysis, thalidomide treatment lowered total myocardial collagen content and the expression of TNF-α, IL-1β, ICAM-1, and VCAM-1. In an animal model of DMCMP, deterioration of LV systolic and diastolic function was partially prevented by thalidomide treatment.

Although it is widely accepted that diabetic polyneuropathy (DPN) is linked to a marked decline in neuromuscular performance, information on the possible impact of type 1 diabetes (T1D) on muscle strength and fatigue remains unclear. The purpose of this study was to investigate the effects of T1D and DPN on strength and fatigability in knee extensor muscles. Thirty-one T1D patients (T1D), 22 T1D patients with DPN (DPN) and 23 matched healthy control participants (C) were enrolled. Maximal voluntary contraction (MVC) and endurance time at an intensity level of 50% of the MVC were assessed at the knee extensor muscles with an isometric dynamometer. Clinical characteristics of diabetic patients were assessed by considering a wide range of vascular and neurological parameters. DPN group had lower knee extensor muscles strength than T1D (-19%) and the C group (-37.5%). T1D group was 22% weaker when compared to the C group. Lower body muscle fatigability of DPN group was 22 and 45.5% higher than T1D and C group, respectively. T1D group possessed a higher fatigability (29.4%) compared to C group. A correlation was found between motor and sensory nerve conduction velocity and muscle strength and fatigability. Patients with T1D are characterised by both a higher fatigability and a lower muscle strength, which are aggravated by DPN. Our data suggest that factors other than nervous damage play a role in the pathogenesis of such defect.

To evaluate the effectiveness or acellular dermal matrix (ADM) with autologous buccal micro mucosa and micro skin graft in vaginoplasty. A retrospective analysis was made on the clinical data of 67 patients with vaginal agenesis treated between July 2006 and June 2013. ADM and mixed particles were used in 20 cases (ADM group) and mixed particles graft in 47 cases (control group) in vaginoplasty. There was no significant difference in age between 2 groups (t=0.233, P=0.816). The depth, diameter, and volume of neovagina, epithelization time, stent needing time, and female sexual function index (FSFI) score were compared between 2 groups. There was no significant difference in operation time and amount of bleeding between 2 groups (t = -1.922, P = 0.059; t = 0.398, P = 0.692). The patients were followed up 11-38 months (mean, 16.08 months). Fifteen cases in ADM group and 29 cases in control group had sexual life after operation. Bleeding after operation occurred in 6 cases (2 in ADM group and 4 in control group). No stenosis was observed. Difference in epithelization time was not statistically significant (t = -1.938, P = 0.057). However, the stent needing time of ADM group was significantly shorter than that of control group (t = 7.020, P = 0.000). The neovagina was ideal in wetness degree, smoothness, flexibility, and hairlessness during follow-up. The depth, diameter, and volume of vagina had no significant difference between 2 groups (P > 0.05) at last follow-up, which were close to normal vagina. The other patients had normal sexual function except 1 patient whose FSFI score was less than 23; no statistically significant difference was found in FSFI score between 2 groups (P > 0.05). On the basis of mixed particles grafting, the ADM could improve trestle structure for resisting contracture. The effectiveness is better than merely mixed particles graft. The procedure has satisfactory anatomical and functional results.

ABSTRACT Objective: To compare speech performance and levels of oral impairment between two types of lingual brackets. Methods: A parallel-group randomized controlled trial was carried out on patients with Class II, Division 1 malocclusion treated at the University of Hama School of Dentistry in Hama, Syria. A total of 46 participants (mean age: 22.3 ± 2.3 years) with maxillary dentoalveolar protrusion were randomly distributed into two groups with 23 patients each (1:1 allocation ratio). Either STb (Ormco) or 7th Generation (Ormco) lingual brackets were applied. Fricative sound/s/ spectrograms were analyzed directly before intervention (T0), one week following premolar extraction prior to bracket placement (T1), within 24 hours of bracket bonding (T2), one month after (T3), and three months after (T4) bracket placement. Patients′ acceptance was assessed by means of standardized questionnaires. Results: After bracket placement, significant deterioration in articulation was recorded at all assessment times in the 7th Generation group, and up to T3 in the STb group. Significant intergroup differences were detected at T2 and T3. No statistically significant differences were found between the two groups in reported tongue irritation levels, whereas chewing difficulty was significantly higher in the 7th Generation group one month after bracket placement. Conclusions: 7th Generation brackets have more interaction with sound production than STb ones. Although patients in both groups complained of some degree of oral impairment, STb appliances appeared to be more comfortable than the 7th Generation ones, particularly within the first month of treatment.

This study investigated the effects of the presence of type 2 diabetes mellitus (T2D) and/or chronic liver disease (CLD) on the incidence and prognosis of dementia during a 10-year period in Korea using a nationwide population-based dataset from the Korea National Health Insurance Service.To assess the impact of T2D and CLD on the incidence of dementia, we included subjects aged ≥60 years without dementia, T2D, and CLD from 2003 to 2005. We created another cohort for evaluating the all-cause mortality in subjects with dementia between 2003 and 2005. The participants were categorized into 4 groups: control (neither CLD nor T2D), CLD-only, T2D-only, and T2D-and-CLD groups, and they were followed up until 2013.The incidence of dementia was higher in the T2D-only group than in the control and CLD-only groups (2.78 vs. 2.04 and 2.00 per 1000 person-years). After adjustment for age, gender, and comorbid conditions, both T2D and CLD increased the risk of any type of dementia; however, the impact of CLD alone was much lower [hazard ratio (HR) 1.07, 95% confidence interval (CI): 1.06-1.08] than that of T2D alone (HR 1.27, 95% CI: 1.27-1.28). The risk of dementia did not significantly change in patients with the co-occurrence of T2D and CLD compared to those with T2D alone. The all-cause mortality rate was the lowest in the control group (2.59 per 1000 person-years) and the highest in the T2D-and-CLD group (3.77 per 1000 person-years). Presence of T2D or CLD alone was associated with higher mortality (HR 1.46 and HR 1.21, respectively) compared with in the absence of both the diseases. Furthermore, the presence of both the diseases further significantly increased the mortality rate compared to the presence of each disease alone (HR 1.67, 95% CI: 1.65-1.69).In conclusion, this study found that the incidence of dementia was much higher in patients with T2D. CLD was associated with a modest increase in risk of dementia; however, there was no additive effect with T2D. In the population with dementia, however, the presence of CLD was associated with high mortality in patients with or without T2D. Copyright © 2017 The Authors.

Clinical nursing practice is important because it helps nursing students experience realities of clinical nursing that cannot be learned through theoretical education. This study aimed to evaluate the effect of an interactive nursing skills mobile application for nursing students. Sixty-six senior nursing students were randomly assigned to experimental or control groups. The experimental group used an interactive nursing skills mobile application for 1 week. The control group was provided with a mobile application containing noninteractive nursing video contents for 1 week. Before (pre-test) and 1 week after (post-test) using the mobile application, participants' knowledge of clinical nursing skills, self-efficacy of nursing practice, and nursing skills performance were assessed. The experimental group showed a significantly higher value for knowledge after 1 week of treatment via their mobile application than the control group (t = 3.34, p = .001). In addition, they showed significantly improved self-efficacy before and after intervention (t = 2.46, p = .017) than the control group. The experimental group's nursing skills performance was also significantly enhanced after intervention (t = 7.05, p < .001), with a significant difference in the degree of improvement (t = 4.47, p < .001). The interactive learner-centered nursing education mobile application with systematic contents was an effective method for students to experience practical nursing skills. Developing and applying a mobile application with other nursing contents that can be effectively used across all range of nursing students is recommended. Copyright © 2018.

The effect of oral administration of lentinan (LTN), a biological response modifier, in the control of systemic immune function was studied in 6-week old male Wistar-Imamichi SPF rats. In the LTN group, 1 mg LTN dissolved in 1 ml physiological saline was administration forcibly into the stomach twice weekly. Physiological saline alone was administered in a similar fashion to the control group. Blood samples were obtained prior to and after four and eight weeks of administration. White blood cells and lymphocyte counts were obtained and lymphocyte subsets were measured using monoclonal antibodies W3/13, W3/25 and 0 X 8 (Sera-Lab), and a laser flow cytometry system (Orthospectrum III, Orthodiagnostic System). The T cell ratio, helper/inducer T (Th) cell ratio, and suppressor/cytotoxic T (Ts) cell ratio were measured. The peripheral white blood cell count and lymphocyte count were not significantly different between the control and LTN groups. After four weeks of LTN administration, however, the LTN group showed a significantly higher T cell ratio, Th cell ratio and Th/Ts cell ratio than did the control group, and the Ts cell ratio was significantly lower. In the groups undergoing administration for eight weeks, no difference was noted in the lymphocyte subsets between the two groups. Oral administration of LTN apparently modulates the systemic immune function through T cell stimulation, especially Th cells, but continued administration may induce a tolerance to the effect of LTN.

The purpose of this study was to evaluate the sensitivity of teeth with MIH in children before and after the use of a tooth mousse containing casein phosphopeptide and amorphous calcium phosphate (CPP-ACP). Forty patients, both males and females, aged from 8 to 13 years old that had a molar with MIH hypersensitivity were included in this study. In the test group (20 subjects), a tooth mousse with CPP-ACP was used while fluoride toothpaste was used in the control group. Dental sensitivity to mechanical and thermal stimuli was evaluated before (T0) and 120 days after the beginning of the treatment (T1). In the test group, the thermal sensitivity decreased significantly (P<0.05) from T0 to T1 (2.4±0.6 to 1.1±0.4) while in the control group resulted very similar (from 2.3±0.5 to 2.2±0.4). Similarly, mechanical sensitivity decreased significantly (P<0.05) from 7.8±1 to 3.8±0.6 while in the control group decreased not significantly (from 7.5±1.3 to 7.2±0.8). No significant difference (P>0.05) was observed by comparing males with females. The use of the remineralizing agent containing CPP-ACP resulted in a significant improvement in dental sensitivity in patients with MIH.

The objective is to study the effects of flurbiprofen axetil (FA) with fentanyl together in postoperative controlled intravenous analgesia (PCIA) on pain intensity, cytokine levels in peripheral blood and adverse reactions of thoracotomy patients. Fifty thoracotomy patients were divided into a FA and a control group, each with 25 cases. Postoperative analgesia was administered in the two groups using PCIA. The pressing times of analgesia pump, the visual analog scale (VAS) scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery and the incidence of adverse drug reactions were recorded. Levels of IL-1β, IL-6, IL-8, IL-2, and TNF-α in peripheral blood were determined before the administration of FA (T0), and at 24 h (T1), 48 h (T2), 72 h (T3) after surgery. The analgesia pump pressing times in the FA group was less than that of the control group. The VAS scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery, were statistically less than those of control group. The incidence rate of nausea and vomiting was insignificantly different between the two groups. Administration of FA together with PCIA in thoracotomy patients can improve postoperative analgesia.

To determine if text message reminders regarding oral hygiene compliance have an influence on the level of compliance within an orthodontic population. In this prospective, randomized, controlled clinical trial, 42 orthodontic patients were assigned to a text message or control group. Parents of patients assigned to the text message group received a reminder text message one weekday each week. Oral hygiene compliance was measured using bleeding index (BI), modified gingival index (MGI), and plaque index (PI), and visual examination of white spot lesion (WSL) development at baseline (T0), two appointments after baseline (T1), and four appointments after baseline (T2). BI, MGI, and PI scores were significantly lower in the text message group than in the control group at T2. A text message reminder system is effective for improving oral hygiene compliance in orthodontic patients.

This pilot study aimed to evaluate the effect of antimicrobial photodynamic therapy (aPDT) as an adjuvant to non-surgical periodontal therapy (NSPT) on periodontal status and glycemic control in patients with type 2 diabetes mellitus and generalized chronic periodontitis. Twelve patients were evaluated at five time points: during the preparation of the patient (T0), during the treatment phase (T1) and after 30 (T2), 90 (T3) and 180 (T4) days. The patients had a mean age of 52.2 years and a 9.58-year history of diabetes, on average, and were divided into two randomized treatment groups: 6 patients received NSPT combined with aPDT (G1) and 6 patients received only NSPT (G2). The aPDT was applied associating the photosensitizing agent methylene blue (10 mg/ ml) with a red laser (660 nm- 40 mW). The total time of exposure was 2 min per tooth. Whitin the limitation of this study, the results showed that the plaque index reduced significantly only in the control group (p = 0.02) at T2 (30 days). For bleeding on probing, both groups showed a significant reduction between T1 and T2, with no difference between groups G1 and G2. Regarding the probing depth, there were no differences between groups, but the parameters decreased over time when compared to T1. The glycated haemoglobin and fructosamine levels did not significantly differ between or within the groups at any time point. When NSPT was combined with aPDT, no additional benefits were observed for the periodontal and metabolic clinical parameters. Copyright © 2018. Published by Elsevier B.V.

To evaluate the efficacy of manual lymphatic drainage (MLD) in improving health-related quality of life (HRQOL), symptomatology, and physical status in patients with chronic venous insufficiency (CVI). Single-blind randomized controlled trial. Health community attendant service. Subjects with CVI (N=41) were randomly assigned to an experimental group (n=20; mean age, 54.6±11.3y) or control group (n=21; mean age, 46.8±11.1y). The experimental group completed 10 lower extremity MLD sessions over 4 weeks and 1 educational session. The control group only attended the educational session. Outcome measures were taken at baseline (t0), at the end of 4 weeks (t1), and after 2 months for follow-up (t2). HRQOL was assessed with the Chronic Venous Insufficiency Quality of Life Questionnaire-20, symptoms (fatigue, heaviness) were assessed with a visual analog scale, severity of the disease was assessed with the Venous Clinical Severity Score (VCSS) (total score, score for each item), leg volumetry was assessed with perimeters, and plantar/dorsiflexion strength and ankle range of motion (ROM) were assessed with dynamometry. A significant interaction group×time effect was found for pain on HRQOL (F2,78=3.507; P=.035; partial η2=.087), clinical severity (F2,78=5.231; P=.007; partial η2=.118), especially for venous edema (assessed with the VCSS), fatigue (F1.67,65.21=4.690; P=.012; partial η2=.107), and heaviness (F1.57,61.32=9.702; P=.001; partial η2=.199), with the experimental group improving from t0 to t1 and t0 to t2 in all of these outcomes. No effect of MLD treatment could be found for ankle muscle strength, ankle ROM, and leg volume. Short-term MLD treatment ameliorates CVI severity and related edema, symptoms, and pain HRQOL in patients with CVI. Copyright © 2015 American Congress of Rehabilitation Medicine.

The discrepancy between the extensive impact of musculoskeletal complaints and the common deficiencies in musculoskeletal examination skills lead to increased emphasis on structured teaching and assessment. However, studies of single interventions are scarce and little is known about the time-dependent effect of assisted learning in addition to a standard curriculum. We therefore evaluated the immediate and long-term impact of a small group course on musculoskeletal examination skills. All 48 Year 4 medical students of a 6 year curriculum, attending their 8 week clerkship of internal medicine at one University department in Berne, participated in this controlled study. Twenty-seven students were assigned to the intervention of a 6×1 h practical course (4-7 students, interactive hands-on examination of real patients; systematic, detailed feedback to each student by teacher, peers and patients). Twenty-one students took part in the regular clerkship activities only and served as controls. In all students clinical skills (CS, 9 items) were assessed in an Objective Structured Clinical Examination (OSCE) station, including specific musculoskeletal examination skills (MSES, 7 items) and interpersonal skills (IPS, 2 items). Two raters assessed the skills on a 4-point Likert scale at the beginning (T0), the end (T1) and 4-12 months after (T2) the clerkship. Statistical analyses included Friedman test, Wilcoxon rank sum test and Mann-Whitney U test. At T0 there were no significant differences between the intervention and control group. At T1 and T2 the control group showed no significant changes of CS, MSES and IPS compared to T0. In contrast, the intervention group significantly improved CS, MSES and IPS at T1 (p < 0.001). This enhancement was sustained for CS and MSES (p < 0.05), but not for IPS at T2. Year 4 medical students were incapable of improving their musculoskeletal examination skills during regular clinical clerkship activities. However, an additional small group, interactive clinical skills course with feedback from various sources, improved these essential examination skills immediately after the teaching and several months later. We conclude that supplementary specific teaching activities are needed. Even a single, short-lasting targeted module can have a long lasting effect and is worth the additional effort.

Different herbs and spices have been used as feed additives for various purposes in poultry production. This study was conducted to assess the effect of feed supplemented with black pepper (Piper nigrum), turmeric powder (Curcuma longa), coriander seeds (Coriandrum sativum) and their combinations on the performance of broilers. A total of 210 (Cobb) one-d-old chicks were divided into seven groups of 30 birds each. The treatments were: a control group received no supplement, 0.5% black pepper (T1), 0.5% turmeric powder (T2), 2% coriander seeds (T3), a mixture of 0.5% black pepper and 0.5% turmeric powder (T4), a mixture of 0.5% black pepper and 2% coriander seed (T5), and a mixture of 0.5% black pepper, 0.5% turmeric powder and 2% coriander seeds (T6). Higher significant values of body weight gain during the whole period of 5 weeks (p<0.001) were observed in broilers on T1, T3, T5, and T6 compared to control. Dietary supplements with T1, T2, T3, and T6 improved the cumulative G:F of broilers during the whole period of 5 weeks (p<0.001) compared with control. The dressing percentage and edible giblets were not influenced by dietary supplements, while higher values of relative weight of the liver (p<0.05) were obtained in T5 and T6 compared to control. The addition of feed supplements in T5 and T6 significantly increased serum total protein and decreased serum glucose, triglycerides and alkaline phosphatase concentrations compared with the control group (p<0.05). Broilers on T6 showed significant decrease in the serum glutamate pyruvate transaminase concentration (p<0.05) compared to control. The broilers having T5 and T6 supplemented feed had relatively greater antibody titre (p<0.001) at 35 d of age than control. It is concluded that dietary supplements with black pepper or coriander seeds or their combinations enhanced the performance and health status of broiler chickens. PMID:25050023

The purpose of this study was to evaluate the effects of a skin camouflage program on disfigurement, self-esteem, social interaction, and body image in female head and neck cancer (HNC) survivors. A prospective, repeated-measures, randomized controlled therapeutic intervention design was used. A total of 66 participants were randomly assigned to each group, with 32 in the experimental group and 34 in the control group. The experimental group received a 4-session skin camouflage program, and the control group received routine care. Patients were assessed at 3 time points: baseline assessment (T0) and then at 1, 2, and 3 months (T1, T2, and T3, respectively) after participating in the skin camouflage program. Patients in the experimental group had significantly less facial disfigurement, depression, fear of social interaction, and anxiety regarding social interaction compared with those in the control group. Participants in both groups had significantly lower levels of facial disfigurement, depression, fear of social interaction, anxiety of social interaction, and body image at the final posttest assessment than at the pretest assessment. There were no differences between the groups and within groups with respect to self-esteem. The 3-month skin camouflage program effectively improved facial disfigurement, fear of social interaction, anxiety of social interaction, and body image of female HNC survivors. A survival care plan should include a skin camouflage program to improve body image perception and decrease anxiety after treatment of HNC. Copyright © 2016 John Wiley & Sons, Ltd.

The aim of this study was to construct an electronic bowel sound recording system and determine its usefulness for the diagnosis of appendicitis, mechanical ileus and diffuse peritonitis. A group of 67 subjects aged 17 to 88 years including 15 controls was examined. Bowel sounds were recorded using an electret microphone placed on the right side of the hypogastrium and connected to a laptop computer. The method of adjustable grids (converted into binary matrices) was used for bowel sounds analysis. Significantly, fewer (p ≤ 0.05) sounds were found in the mechanical ileus (1004.4) and diffuse peritonitis (466.3) groups than in the controls (2179.3). After superimposing adjustable binary matrices on combined sounds (interval between sounds <0.01 s), significant relationships (p ≤ 0.05) were found between particular positions in the matrices (row-column) and the patient groups. These included the A1_T1 and A1_T2 positions and mechanical ileus as well as the A1_T2 and A1_T4 positions and appendicitis. For diffuse peritonitis, significant positions were A5_T4 and A1_T4. Differences were noted in the number of sounds and binary matrices in the groups of patients with acute abdominal diseases. Certain features of bowel sounds characteristic of individual abdominal diseases were indicated. BS: bowel sound; APP: appendicitis; IL: mechanical ileus; PE: diffuse peritonitis; CG: control group; NSI: number of sound impulses; NCI: number of combined sound impulses; MBS: mean bit-similarity; TMIN: minimum time between impulses; TMAX: maximum time between impulses; TMEAN: mean time between impulses.

Theory-based interventions can enhance people's safe water consumption, but the sustainability of these interventions and the mechanisms of maintenance remain unclear. We investigated these questions based on an extended theory of planned behaviour. Seven hundred and ten (445 analysed) randomly selected households participated in two cluster-randomised controlled trials in Bangladesh. Study 1 promoted switching to neighbours' arsenic-safe wells, and Study 2 promoted switching to arsenic-safe deep wells. Both studies included two intervention phases. Structured interviews were conducted at baseline (T1), and at 1-month (T2), 2-month (T3) and 9-month (T4) follow-ups. In intervention phase 1 (between T1 and T2), commitment-based behaviour change techniques--reminders, implementation intentions and public commitment--were combined with information and compared to an information-only control group. In phase 2 (between T2 and T3), half of each phase 1 intervention group was randomly assigned to receive either commitment-based techniques once more or coping planning with reminders and information. Initial well-switching rates of up to 60% significantly declined by T4: 38.3% of T2 safe water users stopped consuming arsenic-safe water. The decline depended on the intervention. Perceived behavioural control, intentions, commitment strength and coping planning were associated with maintenance. In line with previous studies, the results indicate that commitment and reminders engender long-term behavioural change.

To examine the effect of levothyroxine (L-T4), vitamin E or both on oxidative stress status and hippocampal apoptosis in a propylthiouracil (PTU)-induced hypothyroid rat model. Sprague-Dawley rats were randomly divided into five groups: Control, PTU+PTU+L-T4+PTU+Vit E, PTU+Vit E+L-T4. In each group we assessed levels of serum triiodothyronine (T3), tetraiodothyronine (T4), thyroid stimulating hormone (TSH), hippocampus cellular apoptosis index (AI), hippocampus nicotinamide adenine denucleotide hydrogen (NADPH)oxidase and superoxide dismutase (SOD). 1) Compared with the control group, NADPH oxidase levels were significantly increased, and SOD levels were significantly reduced in the PTU groups (p<0.05). 2) Compared to the PTU group, SOD levels were significantly increased in the PTU+Vit E and PTU+L-T4+Vit E group (p<0.05). NADPH oxidase levels were significantly decreased in the PTU+L-T4, PTU+Vit E and PTU+ L-T4+Vit E group (p<0.05). 3) Compared with the control group, hippocampus AI increased significantly in the PTU group (p<0.05). Compared with the PTU group, hippocampus AI was significantly reduced in the PTU+L-T4 group and PTU+L-T4+Vit E group (p<0.05). 4) Hippocampus AI was positively correlated with NADPH oxidase expression levels in hippocampus tissue (r=0.644, p<0.01). Levothyroxine replacement therapy combined with vitamin E reduces hippocampus AI by improving oxidative stress. This study suggested that the mechanisms of hippocampus tissue injury in a hypothyroid rat model is related to hippocampus apoptosis from increased oxidative stress.

Objectives The purpose of this randomized controlled trial was to evaluate the effects of a specialized yoga program for individuals with a spinal cord injury (SCI) on pain, psychological, and mindfulness variables. Materials and methods Participants with SCI (n=23) were outpatients or community members affiliated with a rehabilitation hospital. Participants were randomized to an Iyengar yoga (IY; n=11) group or to a 6-week wait-list control (WLC; n=12) group. The IY group participated in a twice-weekly 6-week seated IY program; the WLC group participated in the same yoga program, after the IY group’s yoga program had ended. Pain, psychological, and mindfulness measures were collected at two time points for both groups (within 1–2 weeks before and after program 1 and at a third time point for the WLC group (within 1 week after program 2). Results Linear mixed-effect growth models were conducted to evaluate the main effects of group at T2 (postintervention), controlling for T1 (preintervention) scores. T2 depression scores were lower (F1,18=6.1, P<0.05) and T2 self-compassion scores higher (F1,18=6.57, P< 0.05) in the IY group compared to the WLC group. To increase sample size and power, the two groups were combined and analyzed across time by comparing pre- and postintervention scores. Main effects of time were found for depression scores, (F1,14.83=6.62, P<0.05), self-compassion, (F1,16.6=4.49, P<0.05), mindfulness (F1,16.79=5.42, P<0.05), mindful observing (F1,19.82=5.06, P<0.05), and mindful nonreactivity, (F1,16.53=4.92, P<0.05), all showing improvement after the intervention. Discussion The results indicated that a specialized 6-week yoga intervention reduced depressive symptoms and increased self-compassion in individuals with SCI, and may also have fostered greater mindfulness.

To study the gene copy number, mRNA transcription and protien expression of programmed cell death 1 (PD-1) gene in primary hepatocellular carcinoma (PHC) patients and normal control individuals (NC) who are anti-HBs positive, and to investigate the variations in PD-1 gene copy numbers and its relationship with PHC. Real-time PCR was adopted to detect the PD-1 gene copy numbers and their mRNA expressions in peripheral blood mononuclear cells (PBMCs) from 24 samples of PHC patients and 26 of NC. Protein expression level of PD-1 on CD8+ T was analyzed by flow cytometry. In terms of number of PD-1 gene copy numbers, the percentage of cases of haploid (single) was 34.62% and 4.17% in PHC group and control group respectively while the percentage of cases of diploid (double) was 61.54% and 95.83% respectively. The difference between the two was statistically significant (chi2 = 7.639, P = 0.006). The rate of cases with double PD-1 gene copy numbers was found to be higher in patients with PHC than in control group. It was also found that the average expression of PD-1 mRNA was 2.35E-03 in control group and 1.23E-03 in PHC group. The expression level was significant lower in PHC group than that in control group when compared by using Mann-whitey technic (U = 153, P = 0.009). Furthermore, the frequency of PD-1 protein expression on CD8+ T cells was 3.72 +/- 0.32 in control group and 16.13 +/- 1.68 in PHC group. The level of PD-1 mRNA expression was higher in PHC and significant differences was shown between two groups (t = -7.073, P = 0.000). Our study suggests that the variation in PD-1 gene copy number may trigger primary hepatocellular carcinoma to HBV carriers. The relationship between the variation of PD-1 gene copy numbers and its association with primary hepatocellular carcinoma is worth further focus.

Using the method of case-control study, people of regional organizations and institutions aged 20 - 60 who received medical health checkup and endocrine patients in General Hospital of Ningxia Medical College and WuZhong city People's Hospital from October 2011 to October 2012 were enrolled in the study. According to the inclusion and exclusion criteria of T2DM patients and control groups, with gender, ethnic and age are not more than 3 years old cases and controls of matching, the T2DM group (case group) of 351 cases and non-T2DM group (control group) of 655 cases were determined. These subjects underwent questionnaire investigation, understand first, like the situation, the way of life, disease and medication history, family history. Physical examination: including height, weight, waist circumference (WC), systolic blood pressure (SBP) and diastolic blood pressure (DBP), and according to the height and weight to calculate body mass index (BMI), and laboratory tests, triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL-C), low density lipoprotein (LDL-C), blood uric acid (UA ), nmda aminotransferase ( AST) , alanine aminotransferase (ALT), blood biochemical indexes. Results Diabetes group of average age (50.28 + 8.32), 194 patients with male, (55.27%), 157 patients with female (44.73%) and control group in average age (50. 17 + 7. 14) , including 337 men (51.45% ) and 318 women (48.55%). Average age, gender, the proportion between the two groups had no statistical significance of difference. The white blood cell value of T2DM group (6.66 x 10(9) ± 1.61 x 10(9)/L) was higher than that of non-T2DM group (6.11 x 10(9) ± 1.49 x 10(9)/L), there was a significant difference (t = -5.430, P < 0.01); Comparing the mean value of white blood cell of Hui (6.459 x 10(9) ± 1.45 x 10(9)/L) and Han nationality (6.169 x 10(9) ± 1.63 x 10(9)/L), there was a significant difference (P < 0.05). T2DM group, the abnormal level of white blood cell was 2.6%, that of non-T2DM group was 0.8%, The T2DM group was significantly higher than that of non-T2DM group (χ2 = 4.168, P = 0.041). Comparing the abnormal level of white blood cell of Hui and Han nationality, there was no significant difference. After adjustment for age, gender, nation, TG, TC, HDL, LDL, ALT, AST and blood glucose, the odds ratios for T2MD were 4.072 in the people with the WBC abnormal people and the WBC normal people. After adjustment for age, gender sick or not, TG, TC, HDL, LDL, ALT, AST and blood glucose, the odds ratios for WBC increased were 1. 582 in the people with the Hui and Han nationality. The WBC count levels are closely associated with type 2 diabetes, and with the increase of the level, the association enhanced gradually, the WBC may be involved in the occurrence and development of type 2 diabetes. there is a certain relationship between ethnic genetic factors and the WBC count level.

To evaluate the effectiveness of an e-learning course compared with a face-to-face lecture on medication calculation. The current knowledge on medication calculation of nursing students and nurses is insufficient to provide safe care. A stratified-clustered quasi-experimental study. A random selection of nursing schools were allocated to the e-learning course (intervention group) (seven schools; 189 students) or face-to-face lecture (control group) (six schools, 222 students). Students in both groups completed a validated medication calculation test (maximum score: 16) prior to the course (T0), immediately after the course (T1) and 3 months later (T2). A linear mixed model was used for data analysis. Medication calculation skills improved significantly more by the face-to-face lecture than e-learning course. Students in both groups significantly improved in medication calculation skills immediately after the course (T1) and 3 months later. The results flattened at T2 with a significant decline in the intervention group between T1 and T2 and a non-significant decline in the control group. Based on a subgroup analysis, improvement in medication calculation skills at T2 could only be observed in vocational-level (sub degree) nursing students receiving a face-to-face course. Both medication calculation courses had a positive effect on medication calculation skills. Students receiving traditional face-to-face lecture improved significantly more than the students receiving the e-learning course. © 2016 John Wiley & Sons Ltd.

Alteration of the careful balance of the ratio of Th1/Th2 cell subsets impacts immune function and plays an important role in the pathogenesis of asthma. There is little research on the impact of changes on the balance of the regulatory T (Treg)/Th17 subset ratio and its possible repercussions for asthma. This investigation used a murine model of asthma to measure the expression levels of Treg and Th17 cells and the levels of their transcription factors Foxp3 and retinoic acid receptor-related orphan nuclear receptor (ROR)γt in bronchial asthma while assessing indexes of airway inflammation. Thirty female SPF BALB/c mice were divided into three equally numbered groups: a normal control, an asthma and a dexamethasone treatment group. All the airway inflammation indexes measured were more prominent in the asthma group and less so in the control group. The percentage of the lymphocyte subset CD4+CD25+Foxp3+ cells in the CD4+ cells in the asthma group was significantly lower than that in the normal control group (P<0.01). The percentage of the lymphocyte subset CD4+IL-17+ cells in the CD4+ cells in the asthma group was significantly higher than that in the normal control group (P<0.01). The ratio of CD4+CD25+Foxp3+ cells/CD4+IL-17+ cells in the asthma group decreased compared with that in the normal control group (P<0.01). The expression level of Foxp3 of the mice in the asthma group was significantly lower than that in the control group (P<0.01). The expression intensity of RORγt in the asthma group was higher than that in the normal control group (P<0.01). Finally, the Foxp3/RORγt protein expression ratio in the asthma group was significantly lower than that in the normal control group (P<0.01). The Foxp3/RORγt protein expression ratio and the airway responsiveness were negatively correlated. The average levels of inflammation markers in the dexamethasone group were intermediate between the other groups. During the course of bronchial asthma the unbalanced expression of Treg and Th17 affects mostly the expression of Foxp3/RORγt, leading to inflammation of the airways. Dexamethasone may inhibit airway inflammation by regulating the balance between Treg and Th17. PMID:28672989

Objectives This study aims to intensively evaluate the effectiveness of mindfulness-based intervention (MBI) on mental illness risks (including psychological distress, prolonged fatigue, and perceived stress) and job strain (job control and job demands) for employees with poor mental health. Methods A longitudinal research design was adopted. In total, 144 participants were randomized to the intervention group or the control group. The intervention group participated in MBI for eight weeks. Measurements were collected for both groups at five time points: at pre-intervention (T1), at mid-intervention (T2), at the completion of intervention (T3), four weeks after intervention (T4), and eight weeks after intervention (T5). Data were analyzed according to the intention-to-treat principle. A linear mixed model with two levels was employed to analyze the repeated measurement data. Results Compared with the control group, the intercepts (means at T3) for the intervention group were significantly lower on psychological distress, prolonged fatigue, and perceived stress when MBI was completed. Even with the demographic variables controlled, the positive effects remained. For growth rates of prolonged fatigue and perceived stress, participants in the intervention group showed a steeper decrease than did the participants in the control group. Regarding job strain, although the intercept (mean at T3) of job demands showed a significant decline when BMI was completed, the significance disappeared when the demographic variables were controlled. Moreover, the other results for job control and job demands did not show promising findings. Conclusion As a workplace health promotion program, the MBI seems to have potential in improving mental illness risks for employees with poor mental health. However, there was insufficient evidence to support its effect on mitigating job strain. Further research on maintaining the positive effects on mental health for the long term and on developing innovative MBI to suit job strain are recommended.

To investigate the effects of lipopolysaccharides (LPS) extracted from Porphyromonas endodontalis (Pe) on the expression of macrophage colony stimulating factor (M-CSF) mRNA and protein in MC3T3-E1 cells and the role of nucler factor-κB (NF-κB) in the process. MC3T3-E1 cells were treated with different concentrations of Pe-LPS (0-50 mg/L) and 10 mg/L Pe-LPS for different hours (0-24 h). The expression of M-CSF mRNA and protein was detected by reverse transcription polymerase chain reaction (RT-PCR) and enzyme-linked immunoadsordent assay (ELISA). The cells untreated by Pe-LPS served as control. The expression of M- CSF mRNA and protein was also detected in 10 mg/L Pe- LPS treated MC3T3-E1 cells after pretreated with BAY 11-7082 for 1 h, a special NF-κB inhibitor. The groups were divided as follows, control group, BAY group (10 µmol/L BAY 11-7082 treated alone MC3T3-E1 cells), Pe-LPS group (10 mg/L Pe-LPS stimulated MC3T3-E1 cells for 6 h), BAY combine with Pe-LPS group (10 µmol/L BAY 11-7082 pretreated cells for 1 h and 10 mg/L of Pe-LPS stimulated MC3T3-E1 cells for 6 h). The level of M- CSF mRNA and protein increased significantly after treatment with different concentrations of Pe-LPS (0-50 mg/L), which indicated that Pe-LPS induced osteoblasts to express M-CSF mRNA and protein in dose dependent manners. The expression of M-CSF protein increased from (35 ± 2) ng/L (control group) to (170 ± 8) ng/L (50 mg/L group). Maximal induction of M-CSF mRNA expression was found in the MC3T3- E1 cells treated with 10 mg/L Pe-LPS for 6 h. After 6 h, the expression of M-CSF mRNA decreased gradually. The expression of M-CSF protein also increased with the treatment of 10 mg/L Pe-LPS for 10 h [(122 ± 4) ng/L]. After 10 h, the expression of M-CSF protein decreased gradually. The mRNA and proteins of M-CSF decreased significantly after pretreatment with 10 µmol/L BAY 11-7082 for 1 h. There was no significant difference between BAY group and the control. Pe-LPS may induce the expression of M-CSF mRNA and protein in MC3T3-E1 cells through the signaling of NF-κB.

Abstract Thermal manipulation during embryogenesis was previously reported to decrease the occurrence of ascites and to potentially improve cold tolerance of broilers. The objective of our study was to explore the effects of the interaction of cold incubation temperatures and cool ambient temperatures until 21 d of age on performance and body temperature. Ross 308 eggs were incubated either under control conditions I0 (37.6°C) or with cyclic cold stimulations I1 (6 h/d at 36.6°C from d 10 to 18 of incubation) or with 2 cold stimulations I2 (30 min at 15°C) at d 18 and 19 of incubation. These treatments were followed by individual rearing and postnatal exposure to either standard rearing temperature T0 (from 33°C at hatching to 21°C at d 21) or continuously lower temperature T2 (from 28°C at hatching to 21°C at d 21) or exposure to cyclically lower temperature T1 (with circadian temperature oscillations). Treatments I1 and I2 did not significantly alter hatchability compared to control incubation (with 94.8, 95.1, and 92.3%, respectively), or hatching BW and overall chick quality. Hatching body temperature (Tb) was 0.5 and 0.3°C higher in I1 than in I0 and I2 groups, respectively (P = 0.007). A doubled occurrence of health problems was observed with T2 condition, regardless of incubation or sex. At d 3, BW was 2% lower with treatment I1 than with I0 and I2 and was 3% higher in T1 and T2 groups than in T0, but these effects disappeared with age. Group T2 presented a 5% higher feed intake than the control group T0 between 3 and 21 d of age (P = 0.025). Feed conversion ratio (FCR) was affected by experimental conditions (P < 0.001), with low FCR values obtained with I2 incubation in control or cyclically cold postnatal conditions. Maximal FCR values were observed in the continuously cold postnatal conditions, in males submitted to control incubation and in females submitted to I1 incubation, revealing sex-dependent effects of the treatments on performance.

There is evidence that substantial weight loss through bariatric surgery (BS) may result in short-term improvement of migraine severity. However, it still remains to be seen whether smaller amounts of weight loss have a similar effect on migraine headache. This study has been designed to compare the effects of weight reduction through BS and non-surgical modifications. Migraine characteristics were assessed at 1 month before (T0), 1 month (T1), and 6 months (T2) after BS (vertical sleeve gastrectomy (VSG) (n = 25) or behavioral therapy (BT) (n = 26) in obese women (aged 18-60 years) with migraine headache. Migraine was diagnosed using the International Classification of Headache Disorders (ICHDIIβ) criteria. There was significant reduction in the visual analog scale (VAS) from the baseline to T1 and T2 in both groups. The number of migraine-free days showed a significant increase within each group (p < 0.001). The BS group had a significant reduction in attack duration (p < 0.001) while there were no changes observed within the BT group. Following the adjustment of ANCOVA models for baseline values of migraine characteristics, age, changes in weight, BMI, body fat, and fat-free mass from T0 to T2, the BS group showed statistically significant lower VAS and duration of migraine attacks and a significantly higher number of migraine-free days than the BT group at T1 and T2 (p ≤ 0.028). Our results indicated that far before significant weight reduction after BS (VSG), there was marked alleviation in the severity and duration of migraine and a significant increase in the number of migraine-free days in obese female migraineurs. However, the effects in the BT group were not comparable with the effects in the BS group.

There are previous independent reports on the anti-thyroid property of Citrus sinensis. This isoflavones and phenolic acid-rich natural agent is widely consumed as dietary supplement, thus the need to investigate its comparative effect with a standard anti-thyroid drug on T4, T3 and thyroid stimulating hormone (TSH) levels. To compare the effect of Citrus sinensis and carbimazole (CARB) on blood levels of thyroid hormones (T4 and T3) and TSH. Male wistar albino rats weighing 100-150 g were employed in this research. The rats were randomly assigned to four groups of seven rats per group. Group I served as control and were administered distilled water while groups II-IV were administered with 1500 mg/kg of Citrus sinensis (fresh orange juice; FOJ), 0.1 μg/g of levothyroxine (LVT) and 0.01 mg/g of CARB, respectively, per oral once daily for 28 days. The animals were sacrificed under chloroform anaesthesia and blood sample collected by cardiac puncture and processed by standard method to obtain serum. TSH, T4 and T3 were assayed with the serum using ARIA II automated radioimmunoassay instrument. The results showed that TSH level was significantly (P < 0.05) decreased in LVT treated group compared with the FOJ group. T4 was significantly (P < 0.05) decreased in the FOJ and CARB groups compared with the control and LVT groups. LVT significantly increased T4 when compared with FOJ group. T3 was significantly (P < 0.05) decreased in the CARB group compared with the control. These findings suggest that FOJ alters thyroid hormones metabolism to reduce their serum levels with a compensatory elevations of TSH level in a direction similar to CARB.

Increasing tinnitus compliance and coping are desirable aims of successful treatment in chronic tinnitus. However, application of established procedures such as tinnitus retraining therapy (TRT) is often relatively short. In addition, the value of tinnitus control instruments (TCI) is questionable, especially for minor severity levels of tinnitus, and the comparability of treatment results is low. To evaluate long-term changes of tinnitus-related distress, defined psychometric data were collected in patients with compensated tinnitus (cT) or decompensated tinnitus (dT) during a standardized 2-yr outpatient tinnitus-coping therapy (TCT). In a prospective clinical investigation, the data of 70 tinnitus patients were recorded at the beginning and at 6-mo intervals, with a final investigation after 24 mo. The first group consisted of 40 patients with cT and dT who were randomly assigned to a treatment group and a waiting-list control group. After a period of 12 mo without treatment, the control group was treated similarly. The tinnitus questionnaire (TQ) of Goebel and Hiller, visual analog scales (VAS), and a severity questionnaire for tinnitus-associated complaints were used as psychodiagnostic instruments. Therapy components consisted of counseling, fitting patients with TCIs (TCI provision), auditory and relaxation training, and psychosomatic care if necessary. A second group of 30 patients with cT receiving TCT without TCI devices was investigated to evaluate the additive efficacy of TCI in cT. The initial TQ score did not differ between the treatment group and the waiting-list control group. After 12 mo, the control group did not show any significant changes, but the treatment group had improved significantly. During TCT, the combined data of both groups showed a statistically significant decrease of the TQ score in dT (59.1 to 34.8) and cT (32.8 to 24.0). These changes were especially reflected by the subscales of cognitive and emotional distress and also by the VAS and the severity questionnaire. dT patients benefitted without dependence on age or duration of pre-existing tinnitus; for cT patients, this was true mainly of the younger and older subjects and for tinnitus lasting for less than 1 yr. TCI provision improved the efficacy of TCT in patients with cT. The psychometric changes demonstrate a clear decrease of tinnitus-related distress in all severity levels of sufficiently treated chronic tinnitus. Long-term TCT induces improvement even up to the time of 24 mo. With TCIs established particularly in patients with dT, our results suggest that a supporting adjustment of TCI devices is helpful in cT to foster quicker rehabilitation. The outpatient interdisciplinary TCT, consisting of cognitive tinnitus desensitization, TCI provision, and psychosomatic support if required, represents a successful treatment strategy for both dT and cT patients.

Objective: To assess the immunogenicity and safety of recombinant B-subunit/whole cell cholera vaccine (rBS/WC) oral cholera vaccine (Ora Vacs) infused with antacids in healthy population at ages of 2-6 years. Methods: Between December 2009 and January 2010, we recruited 900 volunteers aged 2-6 years od through giving out recruitment notice for the eligible children's parents from different vaccination clinics of Chongzuo city in Guangxi Zhuang Autonomous Region. This study was a randomized, double-blind, placebo-controlled trial, and subjects were randomly (2∶1) assigned to receive Cholera vaccine infused with antacids or placebo, and observed for safety. Serum samples of 300 subjects in immunogenicity subgroups (200 for vaccine groups, 100 for control groups) before the 1st dose and 49 d (±3 d) after immunization were collected, and determined for antibody levels against the cholera toxin (anti-CT) and cholera vibriocidal (anti-Vab) with Enzyme-linked immunosorbent assays (ELISA), based on which the GMT was calculated. There were 266 cases paired with the serum samples before and after immunization (177 for vaccine groups, 89 for control groups). The comparison of subjects' age at enrollment and the level of GMT before and after immunization between groups were analyzed by t test. The superiority test for the difference between seroconversion rates of vaccine groups and control groups were analyzed by χ(2) test. Results: Of 900 subjects enrolled, the number of males and females were 503 and 397 respectively (vaccine groups 335 vs . 265, control groups 168 vs . 132), the average ages of vaccine groups and control groups at enrollment were (4.8±1.2) years and (4.9±1.2) years respectively. There were no significant differences between groups in terms of gender and age (χ(2)=0.00, P= 1.000; t= 0.55, P= 0.585). The 2 times increase rates of anti-CT and anti-Vab in vaccine groups after inoculation were 90.96% and 57.63% respectively, which were superiority to those of control groups (15.73% and 29.21%), and significant differences were observed between groups (χ(2)=15.89, χ(2)=3.85, P< 0.001). There were significant differences between vaccine groups and control groups after inoculation in terms of GMTs of anti-CT (1∶647.56 vs . 1∶99.49) and anti-Vab antibodies (1∶16.19 vs . 1∶11.27) ( t values were 15.82 and 3.43, respetively; both P values were<0.05), significant differences were observed in the growth rates when compared the GMTs of anti-CT (6.63 vs . 1.11) and anti-Vab antibodies (1.64 vs . 1.16) before inoculation between vaccine groups and control groups ( t '=17.85 and 4.96, P< 0.001). In terms of safety, the adverse reaction rates in vaccine groups and control groups were 37.67% (226/600) and 36.67% (110/300), respectively,the common adverse reaction including fever, nausea, vomiting, abdominal pain, diarrhea, headache, fatigue, allergies, rash, etc; and the severity degree were mainly for level 1. Conclusion: Ora Vacs infused with antacids could produce an positive effect on immune response and safety.

Expression of peptide transporter 1 (PepT1) and liver-expressed antimicrobial peptide 2 (LEAP-2) in chickens can be influenced by food deprivation, pathological conditions and drug administration. Effect of three putative probiotic Lactobacillus strains and enrofloxacin on the expression of PepT1 and LEAP-2 mRNA was investigated in Ross 308 chickens. One-day-old chicks (n = 24) were allocated to following groups: control (without treatment); group treated with probiotics via feed; group treated with a combination of probiotics and enrofloxacin; and a group given enrofloxacin only. The drug was administered at a dose of 10 mg kg -1 , via drinking water for 5 days. Samples from liver, duodenum and jejunum were collected 126 h after the start of the treatment. Expression levels of PepT1 and LEAP-2 were determined by real-time polymerase chain reaction and were statistically evaluated by Mann-Whitney test. Enrofloxacin administered alone or in combination with probiotics provoked a statistically significant up-regulation of PepT1 mRNA levels in the measured organ sites. These changes can be attributed to a tendency of improvement in utilization of dietary peptide and in body weight gain. LEAP-2 mRNA expression levels did not change significantly in enrofloxacin-treated chickens in comparison with control group.

We aimed to evaluate the acute effect of musical auditory stimulation on heart rate autonomic regulation during endodontic treatment. The study included 50 subjects from either gender between 18 and 40 years old, diagnosed with irreversible pulpitis or pulp necrosis of the upper front teeth and endodontic treatment indication. HRV was recorded 10 minutes before (T1), during (T2), and immediately (T3 and T4) after endodontic treatment. The volunteers were randomly divided into two equal groups: exposed to music (during T2, T3, and T4) or not. We found no difference regarding salivary cortisol and anxiety score. In the group with musical stimulation heart rate decreased in T3 compared to T1 and mean RR interval increased in T2 and T3 compared to T1. SDNN and TINN indices decreased in T3 compared to T4, the RMSSD and SD1 increased in T4 compared to T1, the SD2 increased compared to T3, and LF (low frequency band) increased in T4 compared to T1 and T3. In the control group, only RMSSD and SD1 increased in T3 compared to T1. Musical auditory stimulation enhanced heart rate autonomic modulation during endodontic treatment. PMID:28182118

This study was done to develop and evaluate a drug dosage calculation training program using cognitive loading theory based on a smartphone application. Calculation ability, dosage calculation related self-efficacy and anxiety were measured. A nonequivalent control group design was used. Smartphone application and a handout for self-study were developed and administered to the experimental group and only a handout was provided for control group. Intervention period was 4 weeks. Data were analyzed using descriptive analysis, χ²-test, t-test, and ANCOVA with the SPSS 18.0. The experimental group showed more 'self-efficacy for drug dosage calculation' than the control group (t=3.82, p<.001). Experimental group students had higher ability to perform drug dosage calculations than control group students (t=3.98, p<.001), with regard to 'metric conversion' (t=2.25, p=.027), 'table dosage calculation' (t=2.20, p=.031) and 'drop rate calculation' (t=4.60, p<.001). There was no difference in improvement in 'anxiety for drug dosage calculation'. Mean satisfaction score for the program was 86.1. These results indicate that this drug dosage calculation training program using smartphone application is effective in improving dosage calculation related self-efficacy and calculation ability. Further study should be done to develop additional interventions for reducing anxiety.

Background: This study aimed to test the beneficial effect of grape seed extract (GSE) (Vitis vinifera) and Vitamin C in oxidative stress and reperfusion injury induced by cardiopulmonary bypass (CPB) in coronary artery bypass surgery. Patients and Methods: In this randomized trial, 87 patients undergoing elective and isolated coronary bypass surgery included. The patients were randomly assigned into three groups (n = 29 each): (1) Control group with no treatment, (2) GSE group who received the extract 24 h before operation, 100 mg every 6 h, orally, (3) Vitamin C group who received 25 mg/kg Vitamin C through CPB during surgery. Blood samples were taken from coronary sinus at (T1) just before aortic cross clamp; (T2) just before starting controlled aortic root reperfusion; and (T3) 10 min after root reperfusion. Some clinical parameters and biochemical markers were compared among the groups. Results: There were significant differences in tracheal intubation times, sinus rhythm return, and left ventricular function between treatment groups compared with control (P < 0.05). Total antioxidant capacity was higher (P < 0.05) in both grape seed and Vitamin C groups at T2 and T3 times. In reperfusion period, malondialdehyde level was increased in control group; however, it was significantly lower for the grape seed group (P = 0.04). The differences in the mean levels of superoxide dismutase and glutathione peroxidase among the three groups were not significant (P > 0.05 in all cases). Conclusions: In our patients, GSE and Vitamin C had antioxidative effects and reduced deleterious effects of CPB during coronary artery bypass grafting surgery. PMID:28074795

To explore the effect of the transcutaneous tracheostomy tube in patients with pneumothorax and its clinical value. A prospective randomized controlled trial was conducted. Thirty-two patients with pneumothorax admitted to Department of Critical Care Medicine of Harrison International Peace Hospital of Hebei Medical University from June 2010 to June 2014 were enrolled. The patients were divided into control group and observation group, with 16 cases in each group. Beside the treatment for primary disease, the patients in control group received thoracic close drainage with traditional silica gel tube as performed by thoracic surgeons, and those in observation group received thoracic close drainage with transcutaneous tracheostomy tube by intensive care doctors. The curative effect and complications of the two groups were observed. Compared with control group, the time from diagnosis to operation (minutes:8.00 ± 1.36 vs. 23.06 ± 3.83, t=14.790, P=0.000) and the operation time were significantly shortened (days:5.37 ± 1.02 vs. 7.31 ± 1.70, t=7.286, P=0.000), the frequency of drainage tube replacement (times: 0.18 ± 0.40 vs. 3.87 ± 1.14, t=12.128, P=0.000) and the times of repeated chest radiography (times:1.12 ± 0.34 vs. 2.93 ± 0.77, t=8.589, P=0.000) in observation group were significantly reduced, the length of hospital day was significantly shortened (days:8.30 ± 1.37 vs. 24.56 ± 5.62, t=17.289, P=0.000), the rates of dislocation of drainage tube (0 vs. 3 cases), obstruction of the tube (0 vs. 5 cases), and subcutaneous emphysema (3 vs. 16 cases) were reduced obviously, but there was no difference in incidence of incision infection (1 vs. 3 cases) and infection of thoracic cavity (0 vs. 2 cases). The usage of transcutaneous tracheostomy tube in patients with pneumothorax is safe and simple. Doctors in ICU can independently do this procedure, and its effect is positive.

AIM: To investigate the clinical response of gastro-esophageal reflux disease (GERD) symptoms to exclusion diets based on food intolerance tests. METHODS: A double blind, randomized, controlled pilot trial was performed in 38 GERD patients partially or completely non-responders to proton pump inhibitors (PPI) treatment. Fasting blood samples from each patients were obtained; leukocytotoxic test was performed by incubating the blood with a panel of 60 food items to be tested. The reaction of leukocytes (rounding, vacuolization, lack of movement, flattening, fragmentation or disintegration of cell wall) was then evaluated by optical microscopy and rated as follows: level 0 = negative, level 1 = slightly positive, level 2 = moderately positive, and level 3 = highly positive. A “true” diet excluding food items inducing moderate-severe reactions, and a “control” diet including them was developed for each patient. Then, twenty patients received the “true” diet and 18 the “control” diet; after one month (T1) symptoms severity was scored by the GERD impact scale (GIS). Hence, patients in the “control” group were switched to the “true” diet, and symptom severity was re-assessed after three months (T2). RESULTS: At baseline (T0) the mean GIS global score was 6.68 (range: 5-12) with no difference between “true” and control group (6.6 ± 1.19 vs 6.7 ± 1.7). All patients reacted moderately/severely to at least 1 food (range: 5-19), with a significantly greater number of food substances inducing reaction in controls compared with the “true” diet group (11.6 vs 7.0, P < 0.001). Food items more frequently involved were milk, lettuce, brewer’s yeast, pork, coffee, rice, sole asparagus, and tuna, followed by eggs, tomato, grain, shrimps, and chemical yeast. At T1 both groups displayed a reduction of GIS score (“true” group 3.3 ± 1.7, -50%, P = 0.001; control group 4.9 ± 2.8, -26.9%, P = 0.02), although the GIS score was significantly lower in “true” vs “control” group (P = 0.04). At T2, after the diet switch, the “control” group showed a further reduction in GIS score (2.7 ± 1.9, -44.9%, P = 0.01), while the “true” group did not (2.6 ± 1.8, -21.3%, P = 0.19), so that the GIS scores didn’t differ between the two groups. CONCLUSION: Our results suggest that food intolerance may play a role in GERD symptoms development, and leucocytotoxic test-based exclusion diets may be a possible therapeutic approach when PPI are not effective or indicated.

AIM: To attempt rectal administration of rebamipide in the treatment of ischemic colitis patients with ulcers, and evaluate its effects. METHODS: We compared 9 ischemic colitis patients (2 men, 7 women) with ulcers treated by bowel rest only from 2000 to 2005 (conventional therapy group), with 6 patients (2 men, 4 women) treated by rebamipide enema therapy in 2006 (rebamipide enema therapy group) and analyzed the mean duration of fasting and hospitalization, degree of ulcer healing, and decrease in WBC count for the two groups. RESULTS: The mean duration of fasting and hospitalization were 2.7 ± 1.8 d and 9.2 ± 1.5 d in the rebamipide group and 7.9 ± 4.1 d and 17.9 ± 6.8 d in the control group, respectively, and significantly reduced in the rebamipide group (t = -2.915; P = 0.0121 and t = -3.054; P = 0.0092). As for the degree of ulcer healing at 7 d after admission, the ulcer score was reduced by 3.5 ± 0.5 (points) in the rebamipide group and 2.8 ± 0.5 (points) in the control group (t = 1.975; P = 0.0797), while the decrease in WBC count was 120.0 ± 55.8 (× 102/μL) in the rebamipide group and 85.9 ± 56.8 (× 102/μL) in the control group (t = 1.006; P = 0.3360). CONCLUSION: In left-sided ischemic colitis patients with ulcers, rebamipide enema therapy significantly reduced the duration of fasting and hospitalization, recommending its use as a new and effective therapeutic alternative.

Abstract The impact of the investigational human immunodeficiency virus type 1 (HIV-1) F4/AS01B vaccine on HIV-1 viral load (VL) was evaluated in antiretroviral therapy (ART)-naive HIV-1 infected adults. This phase IIb, observer-blind study (NCT01218113), included ART-naive HIV-1 infected adults aged 18 to 55 years. Participants were randomized to receive 2 (F4/AS01B_2 group, N = 64) or 3 (F4/AS01B_3 group, N = 62) doses of F4/AS01B or placebo (control group, N = 64) at weeks 0, 4, and 28. Efficacy (HIV-1 VL, CD4+ T-cell count, ART initiation, and HIV-related clinical events), safety, and immunogenicity (antibody and T-cell responses) were evaluated during 48 weeks. At week 48, based on a mixed model, no statistically significant difference in HIV-1 VL change from baseline was demonstrated between F4/AS01B_2 and control group (0.073 log10 copies/mL [97.5% confidence interval (CI): −0.088; 0.235]), or F4/AS01B_3 and control group (−0.096 log10 copies/mL [97.5% CI: −0.257; 0.065]). No differences between groups were observed in HIV-1 VL change, CD4+ T-cell count, ART initiation, or HIV-related clinical events at intermediate timepoints. Among F4/AS01B recipients, the most frequent solicited symptoms were pain at injection site (252/300 doses), fatigue (137/300 doses), myalgia (105/300 doses), and headache (90/300 doses). Twelve serious adverse events were reported in 6 participants; 1 was considered vaccine-related (F4/AS01B_2 group: angioedema). F4/AS01B induced polyfunctional F4-specific CD4+ T-cells, but had no significant impact on F4-specific CD8+ T-cell and anti-F4 antibody levels. F4/AS01B had a clinically acceptable safety profile, induced F4-specific CD4+ T-cell responses, but did not reduce HIV-1 VL, impact CD4+ T-cells count, delay ART initiation, or prevent HIV-1 related clinical events.

To test whether a multistrategy intervention enhanced recovery immediately and longitudinally in patients with severe to moderate upper extremity (UE) paresis. Double-blind, randomized controlled trial with placebo control. Outpatient department of a local medical center. People (N=25) with chronic stroke were randomly assigned to 1 of 2 groups: a transcranial direct current stimulation with sensory modulation (tDCS-SM) group (n=14; mean age ± SD, 55.3±11.4y) or a control group (n=11; mean age ± SD, 56.9±13.5y). Eight-week intervention. The tDCS-SM group received bilateral tDCS, bilateral cutaneous anesthesia, and high repetitions of passive movements on the paretic hand. The control group received the same passive movements but with sham tDCS and sham anesthesia. During the experiment, all participants continued their regular rehabilitation. Voluntary UE movement, spasticity, UE function, and basic activities of daily living. Outcomes were assessed at baseline, at postintervention, and at 3- and 6-month follow-ups. No significant differences were found between groups. However, there was a trend that the voluntary UE movement improved more in the tDCS-SM group than in the control group, with a moderate immediate effect (partial η 2 [η p 2 ]=.14, P=.07) and moderate long-term effects (3-mo follow-up: η p 2 =.17, P=.05; 6-mo follow-up: η p 2 =.12, P=.10). Compared with the control group, the tDCS-SM group had a trend of a small immediate effect (η p 2 =.02-.04) on reducing spasticity, but no long-term effect. A trend of small immediate and long-term effects in favor of tDCS-SM was found on UE function and daily function recovery (η p 2 =.02-.09). Accompanied with traditional rehabilitation, tDCS-SM had a nonsignificant trend of having immediate and longitudinal effects on voluntary UE movement recovery in patients with severe to moderate UE paresis after stroke, but its effects on spasticity reduction and functional recovery may be limited.

Type 1 diabetes is a genetically conditioned autoimmune disease. Genes that account for strong clustering of the disease susceptibility are located within the HLA region. There is also considerable individual variation in the immune response and role of cytokine genes in the disease predisposition. The aim of our research was identification of the genetically controlled TNF-alpha, IL-10, IL-6, IFN-gamma secretion profile in children with diabetes type 1. We have examined 36 children with diabetes type 1 and 36 healthy individuals. DNA was extracted from mononuclear peripheral blood cells. For identification of the cytokine polymorphism PCR-SSP method was used. Patients with diabetes type 1 differ from the group of healthy persons in the cytokine synthesis level and in the cytokine genotypes distribution. Genotype TNF-alpha (A/G) as well as IL-10 (ATA/ATA) was found only in group of children with diabetes but not in the control group. Genotypes IL-10 (GCC/GCC), IL-6 (C/C), IFN-gamma (T/T) were observed with decreased frequency in children with diabetes type 1. No differences between patients and control group in the frequency of IL-10 (GCC/ACC) (GCC/ATA), (ACC/ACC) (ACC/ATA) IL-6 (G/G), (G/C) and IFN-gamma (T/A), (A/A) genotypes were observed. Children with diabetes type 1 were more frequent "high producers" of TNF-alpha and IL-6. It is possible to us molecular method to estimate the genetically controlled immune reactivity. It is a very important immunogenetic factor of the disease predisposition.

To evaluate the characteristics of postoperative refractive status in age-related cataract patients with shallow anterior chamber and the correlation between pre-operative anterior chamber depth and postoperative refractive status. Prospective case-control study. Sixty-eight cases (90 eyes) with age-related cataract were recruited from October 2010 to January 2012 in People's Hospital Peking University including 28 cases (34 eyes) in control group and 40 cases (56 eyes) in shallow anterior chamber group according to anterior chamber depth (ACD) measured by Pentacam system. Axial length and keratometer were measured by IOL Master and intraocular lens power was calculated using SRK/T formula. Postoperative refraction, ACD and comprehensive eye examination were performed at 1 month and 3 months after cataract surgery. Using SPSS13.0 software to establish a database, the two groups were compared with independent samples t-test and correlation analysis were performed with binary logical regression. The postoperative refractive deviation at 1 month were (-0.39 ± 0.62) D in control group and (+0.73 ± 0.26) D in shallow anterior chamber group respectively which present statistical significance between the two groups (P = 0.00, t = 3.67); the postoperative refractive deviation in 3 month was (-0.37 ± 0.62) D in control group and (+0.79 ± 0.28) D in shallow anterior chamber group operatively which present statistical significance between the two groups (P = 0.00, t = 3.33). In shallow anterior chamber group, with the shallower of ACD, the greater of refractive deviation (P = 0.00, r1 month = -0.57, r3 months = -0.61). Hyperopic shift existed in age-related cataract patients with shallow anterior chamber and the shallower of ACD was, the greater of hyperopic shift happened.

In the present article, we aimed to compare the cardiometabolic risk between overweight children with and without type 1 diabetes (T1DM). Therefore, data with regard to cardiometabolic risk parameters of 44 overweight Caucasian children (3-18 years) with T1DM were matched with 44 overweight peers without T1DM for sex, ethnicity, age and standard deviation score of BMI (Z-BMI). Detailed history was taken, information regarding anthropometrics and family history were collected and blood pressure was measured. Blood samples were collected for evaluation of lipid profiles (fasting in controls, non-fasting in T1DM children), alanine aminotransferase and HbA1c (in children with T1DM). It was found that overweight children with T1DM had lower median standard deviation score of waist circumference (Z-WC) as compared to the overweight control group [median, 2.0 (interquartile range, IQR, 1.5-2.3) vs. 2.6 (IQR, 2.0-2.9), P < 0.001]. After adjustment for Z-WC, in children with T1DM, median high-density lipoprotein cholesterol levels were significantly higher and median low-density lipoprotein cholesterol lower in T1DM children, as compared to their peers without T1DM [1.40 (IQR, 1.2-1.5) vs. 1.2 (IQR, 1.0-1.3) and 2.7 (IQR, 2.5-3.2) vs. 3.0 (IQR, 2.5-3.4), respectively, all P < 0.01]. When dividing children according to glycaemic status, children with suboptimal glycaemic control had higher values of triglycerides as compared to well-controlled children [1.3 (IQR, 1.0-1.8) vs. 0.96 (IQR, 0.80-1.2), P = 0.036]. In conclusion, overweight children with T1DM have a more favourable lipid profile, as compared to non-diabetic overweight controls, in spite of a higher frequency of a positive family history of CVD, T2DM and hypertension. Still, paediatricians should give extra attention to cardiometabolic risk factors within this vulnerable group, taking into account the already high cardiometabolic risk.

The purpose of this quasi-experimental study was to assess the efficacy of a family-based (FB) weight-loss and behavior-modification intervention among overweight/obese children (age 9-11 years) and their parents in Taiwan. The intervention group (52 child-parent dyads) participated in an FB program for 7 weeks. The control group (55 child-parent dyads) received an educational pamphlet about obesity prevention. The children's body mass index (BMI) z-scores were the primary outcome variable. The parents' BMI, high-calorie (HC) food-intake behaviors, screen-related behaviors, and restrictions on children's consumption of HC foods and screen-related behaviors and the availability of HC foods at home were the secondary outcome variables. Outcome variables were measured at baseline (T0), at the end of the intervention (T1), and 4 weeks after the end of the intervention (T2). A linear mixed model was used to assess the efficacy of the FB program. Results indicated that the children's BMI z-scores decreased significantly more from T0 to T2 in the experimental group than in the control group. The decreases in parents' HC food-intake behaviors and availability of HC foods at home and the increase in parental restrictions on children's consumption of HC foods were significantly greater in the experimental than in the control group from T0 to T1 and T0 to T2. The FB program was effective in modifying parental behaviors and the weight of overweight/obese children in a Taiwanese population. © The Author(s) 2015.

We aimed to determine the clinical effects of titanium-prepared, platelet-rich fibrin (T-PRF) on human palatal mucosal wound healing (PMWH) and to identify its effect on time-dependent changes in palatal soft-tissue thickness (PSTT) in terms of histoconduction, which is a new concept. Free gingival graft (FGG) donor sites were treated with T-PRF and compared with an untreated control group. The results of colour match and H 2 O 2 -bubbling tests for complete wound epithelization (CWE) were recorded on days 3, 7, 14 and 21. Pain level, number of analgesics used and bleeding status were recorded for the first 7 days. PSTT was measured at baseline and after 1 and 6 months. Colour match scores of the test group were significantly higher than those of the control group at 7 and 14 days. CWE was observed at a higher frequency in the test group than in the control group on day 14. Post-operative bleeding prevalence was lower in the test group than in the control group for the first 2 days. A time-dependent decrease in PSTT was observed at 1 and 6 months in the control group compared with baseline (baseline, 4.23 ± 0.62 mm; 1 month, 4.01 ± 0.68 mm; and 6 months, 3.93 ± 0.69 mm). However, no significant difference was found in the test group (baseline, 4.29 ± 0.64 mm; 1 month, 4.61 ± 0.51 mm; and 6 months, 4.51 ± 0.58 mm). The T-PRF membrane exhibited positive effects on PMWH. T-PRF, which is a promising autogenous matrix for histoconduction, may also be preferred as an autogenous alternative to connective tissue grafts in the treatment of gingival recessions and peri-implant mucosal recessions.

The purpose of this study was to develop and pilot-test an innovative behavioral intervention in adolescents with type 1 diabetes mellitus (T1DM) incorporating structured care of a pet to improve glycemic control. Twenty-eight adolescents with A1C > 8.5% (69 mmol/mol) were randomly assigned to either the intervention group (care of a Betta splendens pet fish) or the control group (usual care). Adolescents in the intervention group were given instructions to associate daily and weekly fish care duties with diabetes self-management tasks, including blood glucose testing and parent-adolescent communication. After 3 months, the participants in the intervention group exhibited a statistically significant decrease in A1C level (-0.5%) compared with their peers in the control group, who had an increase in A1C level (0.8%) (P = .04). The younger adolescents (10-13 years of age) demonstrated a greater response to the intervention, which was statistically significant (-1.5% vs 0.6%, P = .04), compared with the older adolescents (14-17 years of age). Structured care of a pet fish can improve glycemic control in adolescents with T1DM, likely by providing cues to perform diabetes self-management behaviors. © 2015 The Author(s).

Wilson's disease (WD) is characterized with the accumulation of copper in the liver and brain. The objective of this study is to quantitatively measure the susceptibility changes of basal ganglia and brain stem of pediatric patients with neurological WD using quantitative susceptibility mapping (QSM) in comparison to healthy controls. Eleven patients with neurological WD (mean age 15 ± 3.3 years, range 10-22 years) and 14 agematched controls were prospectively recruited. Both groups were scanned on a 1.5 Tesla clinical scanner. In addition to T 1 - and T 2 -weighted MR images, a 3D multi-echo spoiled gradient echo (GRE) sequence was acquired and QSM images were derived offline. The quantitative measurement of susceptibility of corpus striatum, thalamus of each hemisphere, midbrain, and pons were assessed with the region of interest analysis on the QSM images. The susceptibility values for the patient and control groups were compared using twosample t-test. One patient with WD had T 1 shortening in the bilateral globus pallidus. Another one had hyperintensity in the bilateral putamen, caudate nuclei, and substantia nigra on T 2 -weighted images. The rest of the patients with WD and all subjects of the control group had no signal abnormalities on conventional MR images. The susceptibility measures of right side of globus pallidus, putamen, thalamus, midbrain, and entire pons were significantly different in patients compared to controls (P < 0.05). QSM method exhibits increased susceptibility differences of basal ganglia and brain stem in patients with WD that have neurologic impairment even if no signal alteration is detected on T 1 - and T 2 -weighted MR images.

1. A total of 180 one-day-old turkeys were randomly assigned to 6 equal groups to investigate the effect of feeding time on growth performance, carcass characteristics, meat quality, leg problems and physiological responses of growing turkeys under the high temperature conditions of summer. 2. Birds of the first group were ad libitum fed and were considered as the controls (C). The second group (T1) was given 80% of diet in the morning and 20% of diet in the afternoon, the third group (T2) was given 60% of diet in the morning and 40% of diet in the afternoon, the fourth group (T3) was given 40% of diet in the morning and 60% of diet in the afternoon, the fifth group (T4) was given 20% of diet in the morning and 80% of diet in the afternoon and the sixth group (T5) was given 100% of diet in the afternoon. 3. Body weight, body weight gain and feed conversion ratio were improved with T2, T3, T4 and T5 in comparison to control or T1 under heat stress conditions. No significant impacts on carcass traits and meat quality due to changing the time of feeding were seen, except for tenderness and juiciness. 4. Feeding in the afternoon (100%) decreased body temperature and tonic immobility test score, which were positively related with the health condition of the birds. 5. The incidence of leg problems, plumage condition and breast blisters were not significantly different among the experimental groups. 6. It is concluded that feeding turkeys mainly or totally in the afternoon (T4 and T5, birds were fed with 80% or 100% of the diet in the afternoon) can be used as a strategy and a managerial tool for improving growth rate, feed utilisation, carcass and meat quality, as well as health status of growing turkeys reared under hot climate conditions.

In the absence of large, prospective, placebo-controlled studies of longer duration, substantial evidence regarding the safety and risk of testosterone (T) therapy (TTh) with regard to cardiovascular (CV) outcomes can only be gleaned from observational studies. To date, there are limited studies comparing the effects of long-term TTh in men with hypogonadism who were treated or remained untreated with T, for obvious reasons. We have established a registry to assess the long-term effectiveness and safety of T in men in a urological setting. Here, we sought to compare the effects of T on a host of parameters considered to contribute to CV risk in treated and untreated men with hypogonadism (control group). Observational, prospective, cumulative registry study in 656 men (age: 60.7 ± 7.2 years) with total T levels ≤12.1 nmol/L and symptoms of hypogonadism. In the treatment group, men (n = 360) received parenteral T undecanoate (TU) 1000 mg/12 weeks following an initial 6-week interval for up to 10 years. Men (n = 296) who had opted against TTh served as controls. Median follow-up in both groups was 7 years. Measurements were taken at least twice a year, and 8-year data were analyzed. Mean changes over time between the 2 groups were compared by means of a mixed-effects model for repeated measures, with a random effect for intercept and fixed effects for time, group, and their interaction. To account for baseline differences between the 2 groups, changes were adjusted for age, weight, waist circumference, fasting glucose, blood pressure, and lipids. There were 2 deaths in the T-treated group, none was related to CV events. There were 21 deaths in the untreated (control) group, 19 of which were related to CV events. The incidence of death in 10 patient-years was 0.1145 in the control group (95% confidence interval [CI]: 0.0746-0.1756; P < .000) and 0.0092 in the T-treated group (95% CI: 0.0023-0.0368; P < .000); the estimated difference between groups was 0.0804 (95% CI: 0.0189-0.3431; P < .001). The estimated reduction in mortality for the T-group was between 66% and 92%. There were also 30 nonfatal strokes and 26 nonfatal myocardial infarctions in the control group and none in the T-treated group. Long-term TU was well tolerated with excellent adherence suggesting a high level of patient satisfaction. Mortality related to CV disease was significantly reduced in the T-group.

Background. Type 2 diabetes mellitus (T2DM) is determined by genetic and environmental factors. There have been many studies on the relationship between the composition of the gastrointestinal bacterial flora, T2DM, and obesity. There are no data, however, on the gut microbiome structure in monogenic forms of the disease including Maturity Onset Diabetes of the Young (MODY). Methods. The aim of the investigation was to compare the qualitative parameters of the colonic flora in patients with HNF1A-MODY and T2DM and healthy individuals. 16S sequencing of bacterial DNA isolated from the collected fecal samples using the MiSeq platform was performed. Results. There were significant between-group differences in the bacterial profile. At the phylum level, the amount of Proteobacteria was higher (p = 0.0006) and the amount of Bacteroidetes was lower (p = 0.0005) in T2DM group in comparison to the control group. In HNF1A-MODY group, the frequency of Bacteroidetes was lower than in the control group (p = 0.0143). At the order level, Turicibacterales was more abundant in HNF1A-MODY group than in T2DM group. Conclusions. It appears that there are differences in the gut microbiome composition between patients with HNF1A-MODY and type 2 diabetes. Further investigation on this matter should be conducted.

Background Whether the presence of type 2 diabetes mellitus (T2DM) increases the risk of hepatocellular carcinoma (HCC) in hepatitis B virus (HBV) cirrhosis patients is controversial. We conducted a retrospective case-control study to evaluate this issue. Material/Methods We considered all patients diagnosed with HBV-related liver cirrhosis at our hospital from July 2011 to June 2014. The case (n=91) and control (n=91) groups were HBV cirrhosis patients with and without T2DM, respectively. They were matched at a ratio of 1: 1 according to the individual age (±2 years) and same sex and Child-Pugh score. Results None of the baseline data were significantly different between the 2 groups. The percentage of HCC was similar between the 2 groups (case versus control group: 34.1% versus 46.2%, P=0.13). In the case group, sex (P=0.002), alkaline phosphatase (P<0.001), γ-glutamine transferase (P=0.001), and sodium (P=0.003) were associated with the risk of HCC. In the control group, platelet (P=0.041), alanine aminotransferase (P=0.034), aspartate aminotransferase (P=0.026), alkaline phosphatase (P<0.001), and γ-glutamine transferase (P<0.001) were associated with the risk of HCC. Conclusions T2DM may not be a risk factor for the presence of HCC in HBV cirrhosis. PMID:28689209

The purpose of this study was to investigate the acute effects of whole body vibration at optimal frequency, on postural control in blind subjects. Twenty-four participants, 12 congenital blind males (Experimental Group), and 12 non-disabled males with no visual impairment (Control Groups) were recruited. The area of the ellipse and the total distance of the center of pressure displacements, as postural control parameters, were evaluated at baseline (T0), immediately after the vibration (T1), after 10 min (T10) and after 20 min (T20). Whole body vibration protocol consisted into 5 sets of 1 min for each vibration, with 1 min rest between each set on a vibrating platform. The total distance of center of pressure showed a significant difference (p < 0.05) amongst groups, while the area remained constant. No significant differences were detected among times of assessments, or in the interaction group × time. No impairments in static balance were found after an acute bout of whole body vibration at optimal frequency in blind subjects and, consequently, whole body vibration may be considered as a safe application in individuals who are blind.

Post-operative oedema and ecchymosis represent early post-operative complications, impacting negatively on the final aesthetic outcome of each surgical procedure. In particular, such complications are very frustrating for patients and-sometimes-are difficult to be managed by surgeons. Several strategies are available for managing oedema, although some side effects have been reported. A new promising compound for the management of oedema is Venoplant, and this study aims to assess its effectiveness in decreasing post-operative oedema. Patients were randomly allocated for receiving three different treatments: (1) Venoplant tablets and Venoplant gel; (2) only Venoplant tablets; and (3) not treated with Venoplant. The aesthetical outcome has been evaluated using the Global Aesthetic Improvement Scale (GAIS), compiled by both patient and clinician. The GAIS scale was administered several times: the day following the surgical procedure (T0) after 3 days (T1), after 7 days (T2), after 15 days (T3) and after 1 month (T4). Forty-three patients participated in the study. According to patient's evaluations, at T0 in Group 1 and in Group 2 a significant statistical difference was found compared to the control group (p < 0.001 and p < 0.05, respectively). Over time, a significant reduction in swelling and ecchymosis was reported by patients treated with Venoplant (tablets alone or in combination with gel) compared to the control group. According to the physician's assessment, during the different time points of evaluation, a significant reduction in post-operative oedema in Group 1 and in Group 2 compared to the control group was found. Venoplant represents a valid therapeutic strategy for the management of post-operative oedema, guaranteeing a good level of patient satisfaction, in the absence of common side effects which are often associated with other therapies.

This study investigated the effects of dexmedetomidine on heart-type fatty acid binding protein (H-FABP), creatine kinase isoenzymes (CK-MB), and troponin I (cTnI) levels, neurological function and near-term prognosis in patients undergoing heart valve replacement. Patients undergoing heart valve replacement were randomly allocated to remifentanil anesthesia (control group, n=48) or dexmedetomidine anesthesia (observation group, n=48). Hemodynamic parameters were measured before anesthesia induction (T1), 1 min after intubation (T2), 10 min after start of surgery (T3), and on completion of surgery (T4). Levels of plasma H-FABP, CK-MB and cTnI were measured 10 min before anesthesia induction (C1), 10 min after start of surgery (C2), on completion of surgery (C3), 6 h after surgery (C4), and 24 h after surgery (C5). S100β protein and serum neuron-specific enolase (NSE) were detected 10 min before anesthesia induction (C1), and 24 h after surgery (C5). Neurological and cardiac function was evaluated 24 h after surgery. Incidence of cardiovascular adverse events was recorded for 1 year of follow-up. There were no significant differences in the average heart rate between the two groups during the perioperative period. The mean arterial pressure in the observation group was significantly lower than control group (P<0.05). Levels of H-FABP, CK-MB and cTnI at C2, C3, C4 and C5, were significantly higher than C1, but significantly lower in the observation versus control group (P<0.05). Twenty-four hours after surgery, levels of S100β and NSE in both groups were higher than those before induction (P<0.05), but significantly lower in the observation versus control group (P<0.05). Twenty-four hours after surgery, neurological function scores were better, and myocardial contractility and arrhythmia scores significantly lower in the observation versus control group (P<0.05 for all). After follow-up for 1 year, incidence of cardiovascular adverse events was significantly lower in the observation versus control group (P<0.05). Dexmedetomidine anesthesia can effectively maintain hemodynamic stability, reduce myocardial injury and the occurrence of cognitive dysfunction, and improve prognosis in patients undergoing heart valve replacement.

Patients with end-stage renal failure (ESRF) need integrated health care to maintain a desirable quality of life. Studies suggest that post-discharge nurseled telephone support has a positive effect for patients suffering from chronic diseases. But the post-discharge care is under-developed in mainland China and the effects of post-discharge care on patients with peritoneal dialysis have not been conclusive. The purpose of this study is to test the effectiveness of postdischarge nurse-led telephone support on patients with peritoneal dialysis in mainland China. A randomized controlled trial was conducted in the medical department of a regional hospital in Guangzhou. 135 patients were recruited, 69 in the study group and 66 in the control group. The control group received routine hospital discharge care. The study group received post-discharge nurse-led telephone support. The quality of life (Kidney Disease Quality of Life Short Form, KDQOL-SF), blood chemistry, complication control, readmission and clinic visit rates were observed at three time intervals: baseline before discharge (T1), 6 (T2) and 12 (T3) weeks after discharge. Statistically significant effects were found for symptom/problem, work status, staff encouragement, patient satisfaction and energy/fatigue in KDQOL-SF and 84-day (12-week) clinic visit rates between the two groups. The study group had more significant improvement than the control group for sleep, staff encouragement at both T2 and T3, and pain at T2 and patient satisfaction at T3. No significant differences were observed between the two groups for the baseline measures, other dimensions in KDQOL-SF, blood chemistry, complication control, readmission rates at all time intervals and clinic visit rates at the first two time intervals. Post-discharge nurse-led telephone support for patients undergoing peritoneal dialysis is effective to enhance patients' well-being in the transition from hospital to home in mainland China.

To investigate the effects of health education based on integrative therapy of Chinese and Western medicine for type 2 diabetes mellitus (T2DM) from the aspects of knowledge, attitude and practice (KAP), health-related quality of life (HRQoL), body mass index (BMI) and glucose control. Patients were individually randomized into intervention group (receiving integrative education, n=120) and control group (receiving usual education, n=120). The primary outcome was the changes in glycosylated hemoglobin A1c (HbA1c) levels after 3, 6, 9 and 12 months from baseline. Hierarchical linear models (HLMs) were used to assess within-group changes in outcomes over time and between-group differences in patterns of change. Secondary outcomes were KAP scores, HRQoL scores and BMI after 6 and 12 months, paired-sample t test was used to assess within-group changes in outcomes in 6 and 12 months, independent-sample t test was used to assess between-group differences in patterns of change. HbA1c decreased statistically from baseline to 3 months, from 3 to 6 months, from 6 to 9 months and from 9 to 12 months in the intervention group (all P<0.01); and decreased significantly from baseline to 3 months, and from 3 to 6 months in the control group P<0.01). There was a significant between-group difference from baseline to 3 months (P=0.044), from 6 to 9 months (P<0.01) and from 9 to 12 months (P<0.01). Significant improvements in the intervention group along with significant between-group differences were found in KAP and HRQoL scores respectively (all P<0.05). The number in the intervention group of normal weight increased from 56 at baseline to 81 (6 months), 94 (12 months), the number in the control group were 63 (baseline), 69 (6 months), 70 (12 months), the χ 2 of hierarchical analysis of BMI were 6.93 (P=0.075), 10.31 (P=0.016), 15.53 (P<0.01), respectively. Health education based on integrative therapy of Chinese and Western medicine is beneficial to the control of T2DM and should be recommended for T2DM.

Cardiovascular adaptations due to spaceflight are modeled with 6deg head-down tilt bed rest (BR) and result in decreased orthostatic tolerance. We investigated if high-intensity resistive and aerobic exercise with and without testosterone supplementation would improve the heart rate (HR) response to a 3.5-min stand test and how quickly these changes recovered following BR. During 70 days of BR male subjects performed no exercise (Control, n=10), high intensity supine resistive and aerobic exercise (Exercise, n=9), or supine exercise plus supplemental testosterone (Exercise+T, n=8; 100 mg i.m., weekly in 2-week on/off cycles). We measured HR for 2 min while subjects were prone and for 3 min after standing twice before and 0, 1, 6, and 11 days after BR. Mixed-effects linear regression models were used to evaluate group, time, and interaction effects. Compared to pre-bed rest, prone HR was elevated on BR+0 and BR+1 in Control, but not Exercise or Exercise+T groups, and standing HR was greater in all 3 groups. The increase in prone and standing HR in Control subjects was greater than either Exercise or Exercise+T groups and all groups recovered by BR+6. The change in HR from prone to standing more than doubled on BR+0 in all groups, but was significantly less in the Exericse+T group compared to the Control, but not Exercise group. Exercise reduces, but does not prevent the increase in HR observed in response to standing. The significantly lower HR response in the Exercise+T group requires further investigation to determine physiologic significance.

The aim of this experimental study was to evaluate the effects of light-emitting diode-mediated-photobiomodulation therapy (LPT), on the rate of orthodontic tooth movement (TM) and orthodontically induced root resorption, in rats. Twenty male 12-week-old Wistar rats were separated into two groups (control and LPT) and 50 cN of force was applied between maxillary left molar and incisor with a coil spring. In the treatment group, LPT was applied with an energy density of 20 mW/cm(2) over a period of 10 consecutive days directly over the movement of the first molar teeth area. The distance between the teeth was measured with a digital caliper on days 0 (T0), 10 (T1), and 21 (T2) on dental cast models. The surface area of root resorption lacunae was measured histomorphometrically using digital photomicrographs. Mann-Whitney U and Wilcoxon tests were used for statistical evaluation at p < 0.05 level. TM during two different time intervals (T1-T0 and T2-T1) were compared for both groups and a statistically significant difference was found in the LPT group (p = 0.016). The TM amount at the first time period (1.31 ± 0.36 mm) was significantly higher than the second time period (0.24 ± 0.23 mm) in the LPT group. Statistical analysis showed significant differences between two groups after treatment/observation period (p = 0.017). The magnitude of movement in the treatment group was higher (1.55 ± 0.33 mm) compared to the control group (1.06 ± 0.35 mm). Histomorphometric analysis of root resorption, expressed as a percentage, showed that the average relative root resorption affecting the maxillary molars on the TM side was 0.098 ± 0.066 in the LPT group and 0.494 ± 0.224 in the control group. Statistically significant inhibition of root resorption with LPT was determined (p < 0.001) on the TM side. The LPT method has the potential of accelerating orthodontic tooth movement and inhibitory effects on orthodontically induced resorptive activity.

Knee osteoarthritis (OA) conservative treatment aims to delay cartilage degeneration; chondroprotective agents are a valid approach in this sense. A commercially available dietary supplement, CartiJoint Forte, containing glucosamine hydrochloride (GH), chondroitin sulfate (CS) and Bio-Curcumin BCM-95®, was used in this trial. The aim of this study was to assess efficacy and safety of CartiJoint Forte combined with physical therapy in treating subjects with knee OA. A multicenter, prospective, randomized, double blind, placebo-controlled clinical trial. Outpatients referred to the Rehabilitation Departments of two University Hospitals. Fifty-three patients were randomly assigned to an experimental group (N=26) or a control group (N.=27). Experimental subjects received two tablets of CartiJoint Forte each day for 8 weeks, while those in the control group were provided with a placebo. Three subjects dropped out during the course of the study. The two groups both received 20 sessions of physical therapy during the course of the trial. Primary outcome was pain intensity, measured both at motion and at rest, using the Visual Analogue Scale (VAS). A secondary outcome was an assessment of knee function by Western Ontario and McMaster Universities Arthritis Index and Lequesne Index, knee ROM, and two inflammation markers (C-reactive protein and erythrocyte sedimentation rate). Each assessment was carried out at baseline (T0), at 8 weeks (T1) and at 12 weeks (T2). VAS at rest was found to be reduced between T0 and T1, as well as between T0 and T2 (F=13.712; P=0.0001), with no differences between groups (F=1.724; P=0.191). VAS at motion revealed a significant "group × time-check" interaction (F=2.491; P=0.032), with increasing effect of time on VAS reduction (F=17.748; P=0.0001). This was most pronounced in the experimental group at 8 weeks (F=3.437; P=0.045). The Lequesne Index showed reductions at T1 and T2 compared to T0 (F=9.535; P=0.0001), along with group effect, since the experimental group presented a lower score at T2 (F=7.091; P=0.009). No significant changes were found in the knee ROM and inflammation markers. CartiJoint Forte, added to physical therapy, may ameliorate pain and help to improve algofunctional score in knee OA patients. Treatment of knee OA with curcuminoids plus glycosaminoglycans, added to physical therapy, improves VAS at motion and Lequesne Index scores.

It is debatable whether adaptive riding (AR) in children with cerebral palsy (CP) improves postural control and gross motor development. The study aim was to explore the feasibility of an extensive assessment protocol for a randomized controlled trial of therapist-designed adaptive riding (TDAR) in children with CP, with the goals of assessing the effect on child outcomes and evaluating working mechanisms of sitting postural control. A pretest-posttest group design with 2 baseline measurements was used. Six children (1 girl, 5 boys; age range=6-12 years, median age=8 years 9 months) with bilateral spastic CP (Gross Motor Function Classification System level III) participated. Outcomes were evaluated 3 times (T0, T1, and T2) at 6-week intervals. T0 and T1 were baseline measurements; between T1 and T2, a TDAR intervention including an integrated program of postural challenge exercises (2 times per week for 1 hour) was applied. The complex protocol included the 88-item Gross Motor Function Measure (GMFM-88) and electromyographic (EMG) recording of postural muscle activity during reaching while sitting (EMG recording at T1 and T2 only). The protocol was feasible. Median GMFM-88 scores changed from 64.4 at T0 to 66.7 at T1 and from 66.7 at T1 to 73.2 at T2. The change scores for all children exceeded the minimal clinically important difference of the GMFM-88. Five of 6 children showed a decrease in stereotyped top-down recruitment between T1 and T2. Study limitations included the lack of a control group, small sample size, and potential assessor bias for all but the EMG parameters. The feasibility of the complex protocol was established. The data suggested that a 6-week TDAR intervention may improve gross motor function and may reduce stereotyped postural adjustments in children with CP. The limited results warrant replication in a well-powered randomized controlled trial. © 2015 American Physical Therapy Association.

Simple diffusion delivery (SDD) has attained good effects with only tiny amounts of drugs. Fractional anisotropy (FA) and relaxation time T2* that indicate the integrity of fiber tracts and iron concentration within brain tissue were used to evaluate the therapeutic effect of SDD. To evaluate therapeutic effect of SDD in the Parkinson's disease (PD) rat model with FA and T2* parameters. Prospective case-control animal study. Thirty-two male Sprague Dawley rats (eight normal, eight PD, eight SDD, and eight subcutaneous injection rats). Single-shot spin echo echo-planar imaging and fast low-angle shot T 2 WI sequences at 3.0T. Parameters of FA and T2* on the treated side of the substantia nigra were measured to evaluate the therapeutic effect of SDD in a PD rat model. The effects of time on FA and T2* values were analyzed by repeated measurement tests. A one-way analysis of variance was conducted, followed by individual comparisons of the mean FA and T2* values at different timepoints. The FA values on the treated side of the substantia nigra in the SDD treatment group and subcutaneous injection treatment group were significantly higher at week 1 and lower at week 6 than that of the PD control group (SDD vs. PD, week 1, adjusted P = 0.012; subcutaneous vs. PD, week 1, adjusted P < 0.001; SDD vs. PD, week 6, adjusted P = 0.004; subcutaneous vs. PD, week 6, adjusted P = 0.024). The T2* parameter in the SDD treatment group and subcutaneous injection treatment group was significantly higher than that in the PD control group at week 6 (SDD vs. PD, adjusted P = 0.032; subcutaneous vs. PD, adjusted P < 0.001). The combination of FA and T2* parameters can potentially serve as a new effective evaluation method of the therapeutic effect of SDD. 1 Technical Efficacy: Stage 4 J. Magn. Reson.

Athletic trainers must have sound evidence for the best practices in treating and preventing heat-related emergencies and potentially catastrophic events. To examine the effectiveness of a superficial cooling vest on core body temperature (T(c)) and skin temperature (T(sk)) in hypohydrated hyperthermic male participants. A randomized control design with 2 experimental groups. Participants exercised by completing the heat-stress trial in a hot, humid environment (ambient temperature = 33.1 +/- 3.1 degrees C, relative humidity = 55.1 +/- 8.9%, wind speed = 2.1 +/- 1.1 km/hr) until a T(c) of 38.7 +/- 0.3 degrees C and a body mass loss of 3.27 +/- 0.1% were achieved. Ten healthy males (age = 25.6 +/- 1.6 years, mass = 80.3 +/- 13.7 kg). Recovery in a thermoneutral environment wearing a cooling vest or without wearing a cooling vest until T(c) returned to baseline. Rectal T(c), arm T(sk), time to return to baseline T(c), and cooling rate. During the heat-stress trial, T(c) significantly increased (3.6%) and, at 30 minutes of recovery, T(c) had decreased significantly (2.6%) for both groups. Although not significant, the time for return to baseline T(c) was 22.6% faster for the vest group (43.8 +/- 15.1 minutes) than for the no-vest group (56.6 +/- 18.0 minutes), and the cooling rate for the vest group (0.0298 +/- 0.0072 degrees C/min) was not significantly different from the cooling rate for the no-vest group (0.0280 +/- 0.0074 degrees C/min). The T(sk) during recovery was significantly higher (2.1%) in the vest group than in the no-vest group and was significantly lower (7.1%) at 30 minutes than at 0 minutes for both groups. We do not recommend using the cooling vest to rapidly reduce elevated T(c). Ice-water immersion should remain the standard of care for rapidly cooling severely hyperthermic individuals.

The effects of dietary supplementation of sodium selenite (SS) on the reproductive performance and the concentration of selenium, glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and malondialdehyde (MDA) were determined, and expression of glutathione peroxidase 4 (GPx4) and bone morphogenic protein 15 (BMP15) was evaluated. Paired pigeons (n = 864) were fed: T1 received no SS, while T2, T3, and T4 received 0.5, 1.0, and 1.5 mg of SS/kg of dry matter (DM), respectively. Treatments were performed in triplicate with 72 pairs in each replicate. The results showed that selenium supplementation significantly affected pigeon reproductive performance. Birds fed 1.0 mg of SS/kg displayed higher egg production (P > 0.05), higher birth rate, and lower dead sperm rate than the control group (P < 0.05). Selenium and biochemical analyses revealed a higher selenium concentration in the 1.5 mg of SS/kg group than in the control group (P < 0.05), while GSH-Px was higher in the 0.5 mg of SS/kg group than in the control group (P < 0.05). Neither the MDA nor the SOD content were affected significantly in liver, chest muscle, or leg muscle (P > 0.05); however, in plasma, MDA was lower in the control group (P < 0.05), while SOD was higher in the control group (P < 0.05). qRT-PCR results revealed up-regulation of GPx4 in hypothalamus, pituitary and testis tissues in supplemented groups (P < 0.05). However, expression in ovary differed; GPx4 mRNA levels were lower in the 1.5 mg of SS/kg and control groups than in the 1.0 or 0.5 mg of SS/kg groups (P < 0.05). Expression of BMP15 in the hypothalamus, pituitary, and testis tissues was unaffected (P > 0.05), while in ovary, BMP15 was down-regulated in the 1.5 mg of SS/kg group (P < 0.05). These results suggest pigeons supplemented with SS up-regulated GPx4, 1.0 mg of SS/kg exhibited superior reproductive performance, while 1.5 mg of SS/kg increased the selenium concentration, and 0.5 mg of SS/kg up-regulated GSH-Px activity. © 2017 Poultry Science Association Inc.

The putaminal abnormalities detected on 1.5 T magnetic resonance imaging (MRI), such as putaminal atrophy, slit-like hyperintense rim, and hypointensity in the putamen on T2-weighted (T2W) imaging are important signs on differentiating multiple system atrophy with parkinsonism (MSA-P) from Parkinson's disease (PD). However, the putaminal abnormalities may have different manifestations on 3.0 T from those on 1.5 T. To investigate the diagnostic value of putaminal abnormalities on 3.0 T MRI for differentiating MSA-P from PD. The study included a MSA-P group (9 men, 9 women), a PD group (12 men, 14 women), and a control group (11 men, 13 women). All subjects were examined with 3.0 T MRI using the conventional protocol. Putaminal atrophy, T2-hypointensity in the dorsolateral putamenat, and a slit-like hyperintense rim on the lateral putamen were evaluated in each subject. There were no significant differences in the slit-like hyperintense rim (P = 0.782) or T2-hypointensity in the dorsolateral putamen (P = 0.338) among the three groups. Bilateral putaminal atrophy was found in 44.4% (8 of 18) of the MSA-P patients, in only 7.7% (2 of 26) of the PD patients, and in none of the controls. The proportion of subjects with putaminal atrophy was significantly higher in the MAS-P group (P = 0.008) and control group (P < 0.001). The specificity and sensitivity of putaminal atrophy for distinguishing MSA-P from PD was 92.3% and 44.4%, respectively. The signal changes in the putamen on T2W imaging on 3.0 T MRI, including slit-like hyperintense rim and putaminal hypointensity, are not specific signs for MSA-P. Putaminal atrophy is highly specific for differentiating MSA-P from PD and healthy controls, but its insufficient sensitivity limits its diagnostic value. © The Foundation Acta Radiologica 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

BACKGROUND Ischemic stroke (IS) is a leading cause of disability and death and NOTCH3 as a gene related with cardiac-cerebral vascular disease plays a vital role in IS development. However, the reports about the effect of genetic variants in NOTCH3 gene on IS are still few. MATERIAL AND METHODS In order to explore the association between NOTCH3 polymorphisms and IS, 134 patients with IS and 115 controls were enrolled in this case-control study. Polymerase chain reaction was used to do the genotyping of polymorphisms. The χ² test was performed to evaluate Hardy-Weinberg equilibrium (HWE) in the control group and calculate odds ratio (OR) with corresponding 95% confidence interval (CI) which represented the association intensity of NOTCH3 gene polymorphisms and IS risk. RESULTS The genotype frequencies in the control group all confirmed to HWE. TT genotype of 381C>T was associated significantly with IS risk (OR=2.441, 95%CI=1.021-5.837). TC, CC mutant genotypes of 1735T>C had higher frequencies in cases than controls and the difference was significant (P=0.013, 0.041); further, its C allele also increased 0.722 times risk in the case group than controls (OR=1.722, 95%CI=1.166-2.541). CONCLUSIONS NOTCH3 381C>T and 1735T>C polymorphisms were associated with IS and might be the risk factors for IS development, but not NOTCH3 605C>T polymorphism.

Excessive generation of free radicals plays a critical role in the pathogenesis of radiation-induced brain injury. This study was designed to evaluate the protective effect of edaravone, a free radical scavenger, on radiation-induced brain necrosis in patients with nasopharyngeal carcinoma. Eligible patients were randomized 1:1 to the control group and the edaravone group (intravenous 30 mg twice per day for 2 weeks). Both groups received intravenous conventional steroid therapy and were monitored by brain MRI and LENT/SOMA scales prior to the entry of the trial and at 3-months after completing the trial. The primary end point was a 3-month response rate of the proportional changes determined by MRI. The trial is registered at Clinicaltrials.gov Identifier: NCT01865201. Between 2009 and 2012, we enrolled 154 patients. Of whom 137 were eligible for analysis. The volumes of necrosis estimated on T(2)-weighted image showed that 55.6 % edaravone-treated patients (40 out of 72) showed edema decreases ≥25 %, which was significantly higher than that in the control group (35.4 %, 23 out of 65, p = 0.025). Forty-four patients treated with edaravone (61.1 %) reported improvement in neurologic symptoms and signs evaluated by LENT/SOMA scales, while the rate was 38.5 % in the control group (p = 0.006). MRI of the edaravone group showed a significant decrease in area of T(1)-weighted contrast enhancement (1.67 ± 4.69 cm(2), p = 0.004) and the T(2)-weighted edema (5.08 ± 10.32 cm(2), p = 0.000). Moreover, compared with those in control group, patients with edaravone exhibited significantly better radiological improvement measured by T(2)-weighted image (p = 0.042). Administration of edaravone, in adjunct to steroid regimen, might provide a better outcome in patients with radiation-induced brain necrosis.

Women treated with chemotherapy for breast cancer experience subtle cognitive deficits. Research has focused on mean performance level, yet recent work suggests that within-person variability in reaction time performance may underlie cognitive symptoms. We examined intraindividual variability (IIV) in women diagnosed with breast cancer and treated with neoadjuvant chemotherapy. Patients (n = 28) were assessed at baseline before chemotherapy (T1), approximately 1 month after chemotherapy but prior to surgery (T2), and after surgery about 9 months post chemotherapy (T3). Healthy women of similar age and education (n = 20) were assessed at comparable time intervals. Using a standardized regression-based approach, we examined changes in mean performance level and IIV (eg, intraindividual standard deviation) on a Stroop task and self-report measures of cognitive function from T1 to T2 and T1 to T3. At T1, women with breast cancer were more variable than controls as task complexity increased. Change scores from T1 to T2 were similar between groups on all Stroop performance measures. From T1 to T3, controls improved more than women with breast cancer. IIV was more sensitive than mean reaction time in capturing group differences. Additional analyses showed increased cognitive symptoms reported by women with breast cancer from T1 to T3. Specifically, change in language symptoms was positively correlated with change in variability. Women with breast cancer declined in attention and inhibitory control relative to pretreatment performance. Future studies should include measures of variability, because they are an important sensitive indicator of change in cognitive function. Copyright © 2016 John Wiley & Sons, Ltd.

Hyperandrogenism and vascular dysfunction often coexist in women with polycystic ovary syndrome (PCOS). We hypothesized that testosterone compromises cutaneous microvascular dilation in women with PCOS via the endothelin-1 ET-B subtype receptor. To control and isolate testosterone's effects on microvascular dilation, we administered a gonadotropin-releasing hormone antagonist (GnRHant) for 11 days in obese, otherwise healthy women [controls, 22.0 (4) yr, 36.0 (3.2) kg/m2] or women with PCOS [23 (4) yr, 35.4 (1.3) kg/m2], adding testosterone (T; 2.5 mg/day) on days 8–11. Using laser Doppler flowmetry and cutaneous microdialysis, we measured changes in skin microcirculatory responsiveness (ΔCVC) to local heating while perfusing ET-A (BQ-123) and ET-B (BQ-788) receptor antagonists under three experimental conditions: baseline (BL; prehormone intervention), GnRHant (day 4 of administration), and T administration. At BL, ET-A receptor inhibition enhanced heat-induced vasodilation in both groups [ΔCVC control 2.03 (0.65), PCOS 2.10 (0.25), AU/mmHg, P < 0.05]; ET-B receptor inhibition reduced vasodilation in controls only [ΔCVC 0.98 (0.39), 1.41 (0.45) AU/mmHg for controls, PCOS] compared with saline [ΔCVC controls 1.27 (0.48), PCOS 1.31 (0.13) AU/mmHg]. GnRHant enhanced vasodilation in PCOS [saline ΔCVC 1.69 (0.23) AU/mmHg vs. BL, P < 0.05] and abolished the ET-A effect in both groups, a response reasserted with T in controls. ET-B receptor inhibition reduced heat-induced vasodilation in both groups during GnRHant and T [ΔCVC, controls: 0.95 (0.21) vs. 0.51 (13); PCOS: 1.27 (0.23) vs. 0.84 (0.27); for GnRHant vs. T, P < 0.05]. These data demonstrate that androgen suppression improves microvascular dilation in PCOS via ET-A and ET-B receptors. PMID:23921139

In recent years there has been increasing interest in the potential beneficial effects of probiotic bacteria, particularly concerning their immune-modulating effects. Considering the involvement of free radicals in immunological processes, we tried to verify and compare the effects of probiotic (Lactobacillus casei) and conventional yoghurt on antioxidant and oxidant parameters in plasma of humans. In this study female volunteers consumed 100 g/day of probiotic (n = 17) or conventional yoghurt (n = 16) for two weeks (T1-T2) and 200 g/day for another two weeks (T2-T3). A wash-out phase lasting two weeks followed. Total antioxidant capacity (TAC), albumin, and bilirubin were determined photometrically, uric acid was determined by enzymatic methods, and vitamin E, carotenoids, malondialdehyde (MDA), and conjugated dienes (CD) were measured using high-performance liquid chromatography (HPLC). In the period of continuous yoghurt intake (T1-T3), mean concentrations of the antioxidants vitamin E, lycopene, and zeaxanthin decreased significantly (p < 0.01) in the probiotic and in the control group. The average concentrations of lutein, beta-carotene, albumin, uric acid, and bilirubin decreased significantly (p < 0.05) in the probiotic group, only. These alterations led to a significant (p < 0.001) decrease of the average TAC values during the period T1-T3 in both tested groups. In the interval of daily yoghurt consumption (T1-T3) the mean plasma levels of oxidant parameters MDA and CD increased significantly in the probiotic (MDA: p < 0.01; CD: p < 0.001) and the control group (CD: p < 0.01). The average activity of the antioxidant enzyme superoxide dismutase (SOD) was quite constant throughout the study in both groups. The mean activities of GSH-Px and catalase decreased significantly (p < 0.001) in the probiotic group, only after consuming yoghurt daily for four weeks (T1-T3). Although several parameters changed significantly during the study, no significant differences were observed between both investigated groups. Therefore, the results indicate a possible influence of both probiotic and conventional yoghurt on the plasma levels of antioxidant and oxidant parameters.

AIM To examine the long-term effects induced by treatment with the function regulator (FR-2) appliance 7 years post-treatment compared with untreated class II subjects. SUBJECTS AND METHODS The FR-2 sample was collected prospectively and comprised 17 subjects (10 boys and 7 girls, mean age 10.8 years) who were treated with the FR-2 appliance for 1.7 years and re-evaluated 7.1 years after treatment. The step-by-step mandibular advancement was performed gradually (increments up to 3–4 mm), until a ‘super class I’ molar relationship was obtained. The control group consisted of 17 class II subjects (9 boys and 8 girls, mean age 11.3 years) with class II malocclusion, excessive overjet, and class II molar relationship, matched to the treated group as to ages at all times, gender distribution, and stages of skeletal maturity (evaluated by the cervical vertebral maturation method). The lateral cephalograms were analysed at T1 (initial), T2 (final), and T3 (7.1 years post-treatment). The compatibility between the groups and the comparisons of their changes at T1–T2, T2–T3, and T1–T3 intervals were examined by independent sample t-tests (P < 0.05). RESULTS FR-2 treatment provided a significant improvement in the maxillomandibular relationship due to an increase in mandibular length compared with controls, which remained stable over time. Also overjet, overbite, and molar relationship corrections demonstrated stability. Among dentoalveolar changes, only the increased mesial movement of the mandibular molars in the FR-2 group demonstrated stability. CONCLUSIONS Correction of class II malocclusion remained stable 7 years after FR-2 treatment mainly due to the stability of the skeletal changes. PMID:23736378

Although physical activity has been demonstrated to increase cancer survival in epidemiological studies, breast cancer patients tend toward inactivity after treatment. Breast cancer patients were quasi-randomly allocated to two different groups, intervention (IG) and control (CG) groups. The intervention group (n = 111) received an individual 3-week exercise program with two additional 1-week inpatient stays after 4 and 8 months. At the end of the rehabilitation, a home-based exercise program was designed. The control group (n = 83) received a 3-week rehabilitation program and did not obtain any follow-up care. Patients from both groups were measured using questionnaires on physical activity, fatigue, and quality of life (QoL) at five time points, 4 months (t1), 8 months (t2), 12 months (t3), 18 months (t4), and 24 months (t5) after the beginning of the rehabilitation. After 2 years, the level of physical activity (total metabolic rate) increased significantly from 2733.16 ± 2547.95 (t0) to 4169.71 ± 3492.27 (t5) metabolic equivalent (MET)-min/week in the intervention group, but just slightly changed from 2858.38 ± 2393.79 (t0) to 2875.74 ± 2590.15 (t5) MET-min/week in the control group (means ± standard deviation). Furthermore, the internal group comparison showed significant differences after 2 years as well. These results came along with a significantly reduced fatigue syndrome and an increased health-related quality of life. The data indicate that an individual, according to their preferences, and physical-resource-adapted exercise program has a more sustainable impact on the physical activity level in breast cancer patients than the usual care. It is suggested that the rehabilitation program should be personalized for all breast cancer patients.

The aim of this study is to identify the effects of a case management program on knowledge about oral cancer, preventive behavior for oral cancer, and level of uncertainty for patients with oral precancerous lesions. A randomized controlled trial was conducted with two groups, using a pre- and posttest design. The experimental group received a case management program and telephone follow-up sessions; the control group received routine care. Patients were assessed at three time points: first visit to the otolaryngology clinic for biopsy examination (T0), and then at 2 weeks (T1) and 4 weeks (T2) after the biopsy examination. Patients in both groups had significantly higher levels of knowledge about oral cancer, preventive behavior for oral cancer, and lower level of uncertainty at T2 compared to T0. At T2, participants in the experimental group had significantly greater knowledge about oral cancer, more preventive behavior for oral cancer, and less uncertainty compared to those in the control group. The case management program with telephone counseling effectively improved knowledge about oral cancer, preventive behavior for oral cancer, and uncertainty levels in patients with oral precancerous lesions in the four weeks after receiving a biopsy examination. The case management program can be applied with positive results to patients receiving different types of cancer screening, including colorectal, breast, and cervical screening.

To investigate the relationship between C-reactive protein (CRP) + 1444C/T, CRP+1059G/C polymorphisms and chronic periodontitis (CP) in a Han Chinese population. Clinical periodontal parameters [attachment loss (AL) probing depth (PD) and bleeding on probing (BOP)], and serum CRP levels were examined in CP patients (n = 126) and healthy subjects (n = 113). The mean serum CRP level [(1.74 ± 1.67) mg/L] was significantly higher in the CP group than in the control group [(0.57 ± 0.39) mg/L], P < 0.001. In the control group, serum CRP levels were significantly lower in subjects with the CRP +1059 GC and CC genotypes than those with the CRP +1059 GG genotype (P < 0.01). There was no significant difference between genotypes in the CP group. In CP and the control groups, serum CRP levels were significantly higher in subjects with the CRP + 1444 CT and TT genotypes compared to those with the CRP + 1444 CC genotype (P < 0.5). The percentage of CRP + 1059 C allele was 6.7% (17/252) in the CP group and 4.9% (11/226) in the control group. The percentage of CRP + 1444 T allele was 6.3% (16/252) in the CP group and 5.3% (12/226) in the control group (P > 0.5). There was no significant difference between groups in both allele frequencies (P > 0.5). The association of CRP + 1059G/C, CRP + 1444 C/T polymorphisms with CP was not found in a regression model (P > 0.5). The presence of a CRP + 1059C-allele was associated with lower serum CRP levels and the presence of a CRP + 1444T-allele was associated with higher serum CRP levels. However, the data suggested that CRP + 1059G/C, CRP + 1444 C/T polymorphisms were not significantly associated with serum CRP levels of chronic periodontitis patients in ethnic Han Chinese.

This study was conducted to evaluate the prophylactic effect of ginger extract on ethanol-induced reproductive toxicity in male rats. Twenty-eight adult male Sprague-Dawley rats were randomly divided into 4 groups and treated daily for 28 days as follows: control, control-ginger (1 g/kg of body weight [BW]/day by gavage), ethanol group (ethanol 4 g/kg of BW/day by gavage), and ginger-ethanol group. At the end of the experiment, all the rats were sacrificed and their testes were removed and used for measurement of the total homocysteine (tHcy), trace elements, antioxidant enzymes activity, and malondialdehyde (MDA). The results in the ethanol group indicate that ethanol decreased antioxidant enzymes activity and increased MDA and tHcy compared with the control groups ( P < .05). In ginger-ethanol group, ginger improved antioxidant enzymes activity and reduced tHcy and MDA compared to ethanol group ( P < .05). It can be concluded that ginger protects the ethanol-induced testicular damage and improves the hormonal levels, trace elements, antioxidant enzymes activity, and decreases tHcy and MDA.

Interleukin-1β (IL-1β) assumes a centric role in the regulation of immune and inflammatory responses and thus has been recognized in immune mediated diseases like type 2 diabetes mellitus (T2DM). We aimed to investigate expressed level of IL-1β and its relation with IL-1β -511T>C polymorphism in T2DM patients. This study enrolled 80 subjects (50 patients with T2DM and 30 healthy control subjects). Laboratory investigations included fasting (FBG) and 2 h postprandial blood sugar (2 h PBG), HBA1c, lipid profile, and renal function tests. Genotyping of IL-1β -511T>C (rs16944) SNP assay by real-time PCR and relative quantitation of IL-1β gene expression transcript by real-time PCR. T2DM patients had significantly higher FBG and 2 h PBG, HBA1c, LDLc, TC, TG, systolic, and diastolic BP while lower HDLc compared with control group. IL 1- β -511 T>C, CC genotype and C allele were significantly associated with risk of T2DM with odds ratio (OR) 4.73, 95%CI (1.21-18.39) and OR 2.27, 95%CI (1.72-4.40), respectively. Moreover, diabetic patients had significantly higher IL 1- β gene transcript compared with control group (P < 0.001). CC genotype of IL 1- β -511 T > C had the highest significant level of IL 1- β gene transcript demonstrated compared with C/T and T/T genotypes (P < 0.001) in patients. C allele of IL-1 β -511 T >C could be considered risk factor contributor to T2DM and excess level of IL-1 β transcript may disclose to some degree the inflammatory role of cytokines in T2DM. © 2018 Wiley Periodicals, Inc.

Background More than 8.5 million Germans suffer from chronic diseases attributable to smoking. Education Against Tobacco (EAT) is a multinational network of medical students who volunteer for school-based prevention in the classroom setting, amongst other activities. EAT has been implemented in 28 medical schools in Germany and is present in 13 additional countries around the globe. A recent quasi-experimental study showed significant short-term smoking cessation effects on 11-to-15-year-old adolescents. Objective The aim of this study was to provide the first randomized long-term evaluation of the optimized 2014 EAT curriculum involving a photoaging software for its effectiveness in reducing the smoking prevalence among 11-to-15-year-old pupils in German secondary schools. Methods A randomized controlled trial was undertaken with 1504 adolescents from 9 German secondary schools, aged 11-15 years in grades 6-8, of which 718 (47.74%) were identifiable for the prospective sample at the 12-month follow-up. The experimental study design included measurements at baseline (t1), 6 months (t2), and 12 months postintervention (t3), via questionnaire. The study groups consisted of 40 randomized classes that received the standardized EAT intervention (two medical student-led interactive modules taking 120 minutes total) and 34 control classes within the same schools (no intervention). The primary endpoint was the difference in smoking prevalence from t1 to t3 in the control group versus the difference from t1 to t3 in the intervention group. The differences in smoking behavior (smoking onset, quitting) between the two groups, as well as gender-specific effects, were studied as secondary outcomes. Results None of the effects were significant due to a high loss-to-follow-up effect (52.26%, 786/1504). From baseline to the two follow-up time points, the prevalence of smoking increased from 3.1% to 5.2% to 7.2% in the control group and from 3.0% to 5.4% to 5.8% in the intervention group (number needed to treat [NNT]=68). Notable differences were observed between the groups for the female gender (4.2% to 9.5% for control vs 4.0% to 5.2% for intervention; NNT=24 for females vs NNT=207 for males), low educational background (7.3% to 12% for control vs 6.1% to 8.7% for intervention; NNT=30), and migrational background (students who claimed that at least one parent was not born in Germany) at the 12-month follow-up. The intervention appears to prevent smoking onset (NNT=63) but does not appear to initiate quitting. Conclusions The intervention appears to prevent smoking, especially in females and students with a low educational background. PMID:28588007

The aim of the present study was to investigate the effect of various doses of rocuronium on bispectral index (BIS) responses to propofol induction and tracheal intubation, as well as the role of the non-depolarization muscle relaxant rocuronium on the depth of sedation. A total of 72 patients (American Society of Anesthesiologists physical status I-II) were anaesthetized with propofol using a target-controlled infusion, and randomly divided into two sedation level groups (n=36). The patients were divided into 2 groups according to the BIS value: A normal sedation group (group 1), with a stable BIS value at 40-60, and a deep sedation group (group 2), with a BIS value <20 or with burst suppression. Each group was randomly divided into 4 subgroups A-D (n=9) according to the various doses of rocuronium (0.3, 0.6, 0.9 and 1.2 mg/kg). Tracheal intubation was performed after 2 min of rocuronium administration. BIS, electromyography (EMG), heart rate (HR) and mean arterial pressure (MAP) were recorded continuously and averaged over 1 min during baseline (T1), steady state (T2), 2 min after rocuronium infusion (T3), and 0, 2 and 5 min after tracheal intubation. The results demonstrated that HR and MAP decreased significantly at T2 and T3 compared with T1. Following tracheal intubation (L0), HR and MAP significantly increased compared with T2 and T3, and returned to levels similar to those prior to intubation after 5 min. In group 1C and 1D, BIS was significantly decreased at T3 compared with T2; BIS was significantly increased at L0 compared with T3 in group 1A and 1B. EMG at earlier stages of anesthesia was significantly higher compared with other points, and was significantly increased at L0 compared with T3 in group 1A and 1B. These results demonstrated that BIS response may be associated with the dosage of rocuronium in the normal sedation group, although no association was observed with the deep sedation group. Tracheal intubation resulted in marked hemodynamic changes under both normal and deep sedation.

This study was conducted to examine the effect of oral care with an aroma solution on oral status and oral cavity microorganism growth in elderly patients with stroke. A non-equivalent control group, with a pretest-posttest design was used in this study. The participants were assigned to the experimental group (n=30) that received oral care with an aroma solution or the control group (n=31) that received 0.9% saline solution. To identify the effect of the experimental treatments, objective/subjective assessments of oral status and oral cavity microorganism growth were performed using the oral assessment guide, oral perception guide, and oral swab culture. Data were analyzed using Chi-square test, Fisher's exact test, and t-test with the SPSS version 21.0 program. The objective oral status was significantly lower in the experimental group than in the control group (t= -3.64, p<.001). There was no significant difference between the subjective oral status of the experimental group and control groups (t= -1.24, p=.109). Oral microorganism growth was significantly lower in the experimental group than in the control group (t= -7.39, p<.001). These findings indicate that special mouth care using an aroma solution could be an effective oral health nursing intervention for elderly patients with stroke.

Patients with type 1 diabetes (T1D) have an increased risk of cognitive dysfunction. The cognitive decrement is believed to depend on macro- and microvascular complications and long disease duration. Some patients do not develop these complications, but still report cognitive symptoms. We examined if long-standing T1D without complications is associated with lower cognitive performance. A group of patients (n=43) with long-standing T1D (>30years) without micro- or macro vascular complications was compared with a non-diabetic control group (n=86) on six cognitive tests which probed episodic memory, semantic memory, episodic short-term memory, visual attention and psychomotor speed. Each patient was matched with two controls regarding age, gender and education. A linear mixed effect model was used to analyze the data. The mean age was 57years and mean duration was 41years. Patients with diabetes had lower diastolic blood pressure but BMI, waist circumference, systolic blood pressure and smoking did not differ between groups. Patients had lower results than non-diabetic controls in episodic short-term memory (p<0.001) and also lower values on a test that mirrors visual attention and psychomotor speed (p=0.019). Long-standing T1D was associated with lower cognitive performance, regardless of other diabetes-related complications. Copyright © 2017 Elsevier Inc. All rights reserved.

We investigated whether zinc deficiency can affect plasma membrane rheology. Three cell lines, human leukaemia T-cells (Jurkat), rat fibroblasts (3T3) and human neuroblastoma cells (IMR-32), were cultured for 48 h in control medium, in zinc-deficient medium (1.5 microM zinc; 1.5 Zn), or in the zinc-deficient medium supplemented with 15 microM zinc (15 Zn). The number of viable cells was lower in the 1.5 Zn group than in the control and 15 Zn groups. The frequency of apoptosis was higher in the 1.5 Zn group than in the control and 15 Zn groups. Membrane fluidity was evaluated using the 6-(9-anthroyloxy)stearic acid and 16-(9-anthroyloxy)palmitic acid probes. Membrane fluidity was higher in 1.5 Zn cells than in the control cells; no differences were observed between control cells and 15 Zn cells. The effect of zinc deficiency on membrane fluidity at the water/lipid interface was associated with a higher phosphatidylserine externalization. The higher membrane fluidity in the hydrophobic region of the bilayer was correlated with a lower content of arachidonic acid. We suggest that the increased fluidity of the membrane secondary to zinc deficiency is in part due to a decrease in arachidonic acid content and the apoptosis-related changes in phosphatidylserine distribution.

Purpose Previous lumbar spinal surgery (PLSS) is not currently considered as a contraindication for regional anesthesia. However, there are still problems that make spinal anesthesia more difficult with a possibility of worsening the patient's back pain. Spinal anesthesia using combined spinal-epidural anesthesia (CSEA) in elderly patients with or without PLSS was investigated and the anesthetic characteristics, success rates, and possible complications were evaluated. Materials and Methods Fifty patients without PLSS (Control group) and 45 patients with PLSS (PLSS group) who were scheduled for total knee arthroplasty were studied prospectively. A CSEA was performed with patients in the left lateral position, and 10 mg of 0.5% isobaric tetracaine was injected through a 27 G spinal needle. An epidural catheter was then inserted for patient controlled analgesia. Successful spinal anesthesia was defined as adequate sensory block level more than T12. The number of skin punctures and the onset time were recorded, and maximal sensory block level (MSBL), time to 2-segment regression, success rate and complications were observed. Results The success rate of CSEA in Control group and PLSS group was 98.0%, and 93.3%, respectively. The median MSBL in PLSS group was higher than Control group [T4 (T2-L1) vs. T6 (T3-T12)] (p < 0.001). There was a significant difference in the number of patients who required ephedrine for the treatment of hypotension in PLSS group (p = 0.028). Conclusion The success rate of CSEA in patients with PLSS was 93.3%, and patients experienced no significant neurological complications. The MSBL can be higher in PLSS group than Control group.

ADHD affects working memory (WM) and other executive functions (EFs) and thereby negatively impacts school performance, clinical symptoms and functional impairment. The main aim of this study was to analyse the efficacy of computerized WM training (CWMT) on EF rating scales. A secondary objective was to assess its efficacy on performance-based measures of EF (PBMEF), learning, clinical symptoms and functional impairment. 66 children with combined-type ADHD between 7 and 12 years of age from the Child and Adolescent Psychiatric Unit (Spain) were included in this randomized, double-blind, placebo-controlled, parallel-group clinical trial. The participants were randomized (1:1) to an experimental group (EG) (CWMT) (n = 36) or a control group (CG) (placebo training). Assessments were conducted at baseline (T0), 1-2 weeks (T1), and 6 months post-intervention (T2) with the administration of EF rating scales, PBMEF, measures of academic achievement, and questionnaires regarding clinical symptoms and functional impairment. Participants, parents, teachers and professionals who performed the cognitive assessments were blinded. Adjusted multiple linear regression analysis showed significant improvements in EF scales-parent version, from T1 to T2, on the metacognition index [p = 0.03, d' = -0.78 (95 % CI -1.28 to -0.27)] and on WM (also significant at T2-T0) and plan/organize subscales. Significant improvements were also noted in EF scales-teacher version, from T0 to T1 and T2, on the metacognitive index [p = 0.05, d' = -0.37 (95 % CI -0.86 to 0.12) T1-T0, p = 0.02, d' = -0.81 (95 % CI -1.31 to -0.30) T2-T0] and on the initiate, WM, monitor and shift subscales. There were also significant improvements in PBMEF, ADHD symptoms, and functional impairment. CWMT had a significant impact on ADHD deficits by achieving long-term far-transfer effects.

The Potential of Self-assembling Peptides for Enhancement of In Vitro Remineralisation of White Spot Lesions as Measured by Quantitative Laser Fluorescence.

PubMed

Golland, Luca; Schmidlin, Patrick R; Schätzle, Marc

To test the remineralisation potential of a single application of self-assembling peptides or acidic fluoride solution using quantitative light-induced fluorescence (QLF) in vitro. Bovine enamel disks were prepared, and white spot lesions were created on one half of the disk with an acidic buffer solution. After demineralisation, disks were allocated into three groups of 11 specimens each. Group A served as a control group and received no treatment. Group B had a single application of fluoride, and group C was treated once with self-assembling peptides. All disks were embedded in a plastic mold (diameter 15 mm, height 9 mm) with an a-silicone, and remineralisation was initiated using a pH-cycling protocol for five days. Four experimental regions on each disk were measured prior to the start of the study (T0), after demineralisation (T1) and after the remineralisation process (T2) using QLF. After demineralisation, all areas showed a distinct loss of fluorescence, with no statistically significant difference between the groups (ΔF from -69.3 to -10.2). After remineralisation, samples of group B (treated with fluoride) showed a statistically significant fluorescence increase (ΔF from T1 to T2 15.2 ± 7.3) indicating remineralisation, whereas the samples of control group A and group C (treated with self-assembling peptides) showed no significant changes in ΔF of 1.1 ± 1.9 and 2.5 ± 1.9, respectively. Application of self-assembling peptides on demineralised bovine enamel did not lead to increased fluorescence using QLF, indicating either lack of remineralisation or irregular crystals. Increased fluorescence using QLF indicated mineral gain following a single application of a highly concentrated fluoride.

In a previous study we have demonstrated that terminally iodinated hexadecenoic acid (131I-HA) and Thallium-201 (201T1) are comparable in myocardial uptake and distribution in the ischemic dog heart (Westera et al. 1980). In the present study the potential value of 131I-HA was proved in determining regional myocardial metabolism in 19 dog experiments. In ten dogs, 131I-HA was administered 5 min after occlusion of a coronary artery (group II), in six dogs after a 90 min occlusion period (group III). Three dogs served as controls (group I). The turnover rates (t 1/2) of 131I-HA were calculated from mono-exponential time-activity curves, obtained by external detection over ischemic and normally perfused areas during a 30 min period after IV injection of 0.7-1.5 mCi 131I-HA. The t 1/2 values in ischemic regions were found to be significantly longer (group II, 25.1 +/- 2.6 min; group III, 22.6 +/- 1.8 min) than in non-ischemic areas (group II, 12.5 +/- 1.8 min; group III, 14.2 +/- 1.4 min). The t 1/2 values in the control dogs (group I, 13.4 +/- 1.4 min) were not significantly different from the turnover rates in the non-ischemic areas of the occluded hearts. We conclude that the study of turnover rates of radioiodinated free fatty acids allows the determination of regional myocardial metabolism and offers a means to distinguish normally perfused from ischemic myocardial tissue.

Background: The ultra-short course pre-seasonal allergy vaccine, containing appropriate allergoids with the adjuvant monophosphoryl lipid A (MPL), may be effective in treating allergic symptoms. Objective: To explore the timing of the immunological responses to the pre-seasonal allergy vaccine. Methods: Four subcutaneous injections of the active product (Pollinex Quattro) were administered to 20 Parietaria-sensitive intermittent asthmatics (M/F: 12/8; age: 48 ± 10 years; FEV1% predicted: 108% ± 12%) during the 6 weeks prior to the start of the pollen season. Exhaled breath condensate (EBC) was collected immediately before the first and immediately after the last injections (t1 and t2), during the pollen season (t3) and after (t4) the pollen season. EBC was analyzed to determine the levels of pH and 8-isoprostane. Ten Parietaria-sensitive asthmatics served as the untreated control group at t1 and t2. Results: Measured pH levels were 7.64 ± 0.33 at t1, 7.67 ± 0.23 at t2, 7.72 ± 0.34 at t3, and 7.82 ± 0.34 at t4 (P = 0.049 vs baseline). 8-isoprostane levels were significantly lower than baseline at each visit (mean difference from baseline, for t2: −0.77 pg, P = 0.031; for t3: −0.92 pg, P = 0.010; for t4: −0.70 pg, P = 0.048). In the control group, pH levels were 7.73 ± 0.26 at baseline and did not change after 6 weeks (7.79 ± 0.25, P = 0.33). Similarly, the concentrations of 8-isoprostane in the control group were not different from those of the study group at baseline (P = 0.86), and the levels remained unchanged after 6 weeks (P = 0.58). Conclusion: These findings show that the ultra-short course of vaccine adjuvated with MPL acutely reduces the degree of airway inflammation, as expressed by markers of oxidative stress, and suggest that this reduction is maintained during and after the pollen season.

The studio di intervento nel decadimento vascolare lieve (IDEALE study) was an open multicenter Italian study, the aim of which was to assess the effectiveness and safety of oral citicoline in elderly people with mild vascular cognitive impairment. The study was performed in 349 patients. The active or citicoline group was composed of 265 patients and included 122 men and 143 women of mean age 79.9 ± 7.8 years selected from six Italian regions. Inclusion criteria were age ≥ 65 years, Mini-Mental State Examination (MMSE) score ≥ 21, subjective memory complaints but no evidence of deficits on MMSE, and evidence of vascular lesions on neuroradiology. Those with probable Alzheimer's disease were excluded. The control group consisted of 84 patients, including 36 men and 48 women of mean age 78.9 ± 7.01 (range 67-90) years. Patients included in the study underwent brain computed tomography or magnetic resonance imaging, and plasma dosage of vitamin B12, folate, and thyroid hormones. Functional dependence was investigated by scores on the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales, mood was assessed by the Geriatric Depression Scale (GDS), and behavioral disorders using the Neuropsychiatric Inventory scale. Comorbidity was assessed using the Cumulative Illness Rating Scale. An assessment was made at baseline (T0), after 3 months (T1), and after 9 months (T2, ie, 6 months after T1). The main outcomes were an improvement in MMSE, ADL, and IADL scores in the study group compared with the control group. Side effects were also investigated. The study group was administered oral citicoline 500 mg twice a day throughout the study. MMSE scores remained unchanged over time (22.4 ± 4 at T0; 22.7 ± 4 at T1; 22.9 ± 4 at T2), whereas a significant difference was found between the study and control groups, both in T1 and in T2. No differences were found in ADL and IADL scores between the two groups. A slight but not statistically significant difference was found in GDS score between the study and control groups (P = 0.06). No adverse events were recorded. In this study, citicoline was effective and well tolerated in patients with mild vascular cognitive impairment. Citicoline activates biosynthesis of phospholipids in neuronal membranes, increases brain metabolism as well as norepinephrine and dopamine levels in the central nervous system, and has neuroprotective effects during hypoxia and ischemia. Therefore, citicoline may be recommended for patients with mild vascular cognitive impairment.

Elevation in plasma triglycerides (TG) has been widely accepted as a coronary artery disease (CAD) risk predictor. Recently, a new apolipoprotein playing an important role in TG metabolism named apolipoprotein AV (apoAV) was discovered, which is encoded by the APOA5 gene. Several single nucleotide polymorphisms (SNPs) of APOA5 associated with increased TG concentrations have been identified. We here report that a recently identified genetic variant, c.553G>T in the APOA5 gene which causes a substitution of a cysteine for a glycine residue at amino acid residue 185(G185C) is also associated with increased TG levels. To investigate the association between this genetic variation and the risk of CAD, a case-control study comprising 232 patients with CAD and 302 controls from the same area of China was performed. The minor allele frequencies of c.553G > T for the CAD and control groups were 7.76 and 3.97%, respectively (P = 0.008). In both the CAD and control groups, the T allele carriers had higher serum TG levels than homozygous carriers of the major G allele (CAD group: 2.67 +/- 1.48 mmol/l versus 1.95 +/- 1.02 mmol/l, P = 0.021; controls: 2.31 +/- 1.20 mmol/l versus 1.68 +/- 0.95 mmol/l, P = 0.002). After adjustment for age, gender, body mass index, smoking status, glucose and presence of hypertension, the odds ratio (OR) for CAD in the T allele carriers was 2.089 (95% CI = 1.140-3.830, P = 0.017), in comparison to the individuals without the T allele. These results suggest that the APOA5 c.553G > T polymorphism is an important predictor for hypertriglyceridemia and CAD.

To explore the relationship between polymorphisms of interleukin-17A (IL-17A) gene promoter (-197G/A and -692C/T) and the susceptibility to childhood asthma, to further identify the candidate genes for asthma, and to provide a basis for early prevention of asthma in high-risk children. Sixty-five outpatients or inpatients with childhood asthma between August 2013 and August 2015 were assigned to asthma group. Seventy healthy children within the same period were assigned to control group. Using peripheral venous blood from the two groups, PCR with sequence-specific primers was carried out to determine single nucleotide polymorphisms at positions -197G/A and -692C/T in IL-17A gene promoter. A statistical analysis was used to evaluate differences in genotype and allele frequencies between the two groups. Compared with the control group, the asthma group had significantly higher frequencies of TT genotype (29% vs 16%; P=0.012) and T allele (52% vs 42%; P=0.039) at position -692C/T of IL-17A gene. Children with T allele had 1.413-fold higher risk of childhood asthma than those with C allele (OR=1.413, 95%CI: 1.015-1.917). There were no significant differences in genotype and allele frequencies at position -197G/A in IL-17A gene between the two groups (p>0.05). Polymorphisms at position -692C/T in IL-17A gene promoter is associated with the susceptibility to childhood asthma. Children with -692T allele are more susceptible to childhood asthma. There is no significant relationship between polymorphisms at position -197G/A in IL-17A gene promoter and the susceptibility to childhood asthma.

Patients with type 1 diabetes mellitus (T1DM) who are able to adjust their insulin doses according to the carbohydrate content of a meal, as well as their blood glucose, are likely to have improved glycaemic control (Silverstein et al., 2005). With improved glycaemic control, patients have a lower risk of developing long-term microvascular complications associated with T1DM (Diabetes Control and Complications Trial Research Group, 1993). To assess the carbohydrate and insulin knowledge of patients attending our paediatric diabetes clinic at the University Hospital Limerick (UHL), the validated PedCarbQuiz (PCQ) was applied to our clinic population. This study was completed by applying a questionnaire called the PedCarbQuiz (PCQ) to children exclusively attending our paediatric diabetes clinic at UHL. Of the clinic's 220 patients, 81 participated in the study. The average total PCQ score (%) was higher in the continuous subcutaneous insulin infusion (CSII) group compared with the multiple daily insulin (MDI) injection user group (79.1 ± 12.1 versus 65.9 ± 6.6 p = 0.005). The CSII group also had a higher average carbohydrate score (%) compared with the MDI group (79.4 ± 12.4 versus 66.3 ± 16.2, p = 0.004). This study demonstrates that in a representative Irish regional paediatric T1DM clinic, knowledge of carbohydrates and insulin is better among patients treated with CSII compared with MDI. However, knowledge in both groups is poorer than in the original US sample. This study demonstrates that in a representative Irish regional paediatric T1DM clinic, knowledge of carbohydrates and insulin is poorer than in a US based sample, although this knowledge is better among patients treated with CSII compared with MDI. This highlights the need for improved resources for diabetes and carbohydrate counting education for patients with T1DM.

Melatonin is an indolamine hormone, synthesized from tryptophan in the pineal gland primarily. Melatonin exerts both antioxidative and immunoregulatory roles but little is known about melatonin secretion in patients with type 1 diabetes mellitus (T1DM). The aim of this study was to measure serum melatonin levels in patients with T1DM and investigates their relationship with type 1 diabetes mellitus. Forty children and adolescents with T1DM (18 boys and 22 girls) and 30 healthy control subjects (17 boys and 13 girls) participated in the study. All patients followed in Pediatric Endocrinology and Metabolism Unit of Gaziantep University Faculty of Medicine and also control subjects had no hypertension, obesity, hyperlipidemia, anemia, and infection. Blood samples were collected during routine analysis, after overnight fasting. Serum melatonin levels were analyzed with ELISA. There were no statistically significant differences related with age, sex, BMI distribution between diabetic group and control group. Mean diabetic duration was 2.89 ± 2.69 years. The variables were in the equation. Mean melatonin level in diabetic group was 6.75 ± 3.52 pg/ml and mean melatonin level in control group was 11.51 ± 4.74 pg/ml. Melatonin levels were significantly lower in diabetic group compared to controls (P < 0.01). Melatonin was associated with type 1 diabetes mellitus significantly. Because of the varied roles of melatonin in human metabolic rhythms, these results suggest a role of melatonin in maintaining normal rhythmicity. Melatonin may play role in preventing process of inflammation and oxidative stress.

To evaluate the effects of fluoride varnish vs a combination of chlorhexidine-thymol varnish plus a gel containing chlorhexidine and fluoride on oral hygiene and caries prevention in disabled children. Ninety patients aged 3-17 years who were treated under general anaesthesia were randomly assigned into three groups as follows: group 1: Fluor Protector (0.1% fluoride varnish); group 2: Cervitec Plus (1% chlorhexidine- 1% thymol varnish) + Cervitec Gel (0.2% chlorhexidine-0.2% sodium fluoride); group 3: control (toothbrushing only). Mutans streptococci (MS) and lactobacilli (LB) levels, visible plaque index (VPI) and gingival bleeding index (GBI) were evaluated at four stages: T0, before general anaesthesia; T1, one month after treatment; T2, six months after treatment; T3, twelve months after treatment. The data were evaluated using Kruskal-Wallis and Mann-Whitney U-tests (P < 0.05). Groups 1 and 2 showed significantly lower scores than group 3 for all parameters at T1 and T2. No statistically significant difference was detected among any of the the groups at T3 (P > 0.05). The use of materials that include both fluoride and chlorhexidine as routine treatment of children with disability may increase the success of restorations by improving oral hygiene, reduce the need for future restorative treatments and thus the need for general anaesthesia.

This report aimed to explore the association between the change of circulating interleukin-6 (IL-6) in patients and the development of type 1 diabetes mellitus (T1DM). Four databases (PubMed, CNKI, WanFang and Civip) were used to search and list all clinical case-control studies about serum IL-6 level in T1DM patients between Jan 1, 2000 and Aug 31, 2016. A total of 20 case-control studies with 1238 T1DM patients and 742 healthy controls were included in this study. Compared to healthy controls, the serum content of IL-6 in patients with T1DM was significantly greater (overall: SMD, 1.49; 95% CI, 1.04 to 1.93; p<0.001), and notably increased in all subgroup with different age, ethnic and disease duration (all p<0.001). Furthermore, the analysis in subgroup exhibited that serum levels of IL-6 in the age greater than 20-year old (SMD, 1.64; 95% CI, 0.57-2.71; p<0.001), the diseased duration among 0-10years (SMD, 2.43; 95% CI, 1.42-3.44; p<0.001) and the sorted American group (SMD, 1.68; 95% CI, 0.85-2.51; p<0.001) were higher than those in control groups. Patients with T1DM were found to be linked to elevated level of serum IL-6, which the age, ethnic and disease durations in T1DM patients had no effect on the serum IL-6 levels for promoting diabetes mellitus.

Dietary therapy is the mainstay of treatment for diabetes. This study examined the effect of a low glycemic index (GI) multi-nutrient supplement, consumed in place of breakfast, on glycemic control in patients with type 2 diabetes mellitus (T2DM). A total of 71 participants were randomized at a 2:1 ratio into either a breakfast replacement group or a normal breakfast group for a 12-week interventional study. The primary outcome measure was change in hemoglobin A1c (HbA1c). Nutrition status and somatometry were studied as secondary outcomes. The breakfast replacement group displayed a -0.2% absolute reduction in HbA1c (95% CI (confidence interval), -0.38% to -0.07%, p = 0.004), while the HbA1c of the control group increased 0.3% (95% CI, 0.1% to 0.5%, p = 0.005). The baseline Mini Nutritional Assessment score for both groups was 26.0 and no significant changes occurred following intervention. However, there was a statistically significant difference in body mass index between the treatment and control groups (p = 0.032) due to the weight gain in the control group (increased 0.5 kg, 95% CI was 0.2 to 0.9, p = 0.007). These data suggest that breakfast replacement with a low GI multi-nutrient supplement can improve glycemic and weight control in T2DM.

Background Hospital stays and medical interventions are accompanied by worries and anxiety in children and parents. Recent studies show that hospital clowns may reduce anxiety and enhance well-being. However, so far studies are based solely on subjective measures and clowns are usually not integrated in medical routine. With this pilot study, we aim to provide both psychological and physiological evidence of positive effects of clowns' interventions in hospitalized children. Patients/Method In a consecutive randomized intervention-control group design with 31 children aged 4 to 13 years, 17 patients were accompanied by a clown prior to surgery or during ward round (intervention group) and 14 were not (control group). Saliva samples for oxytocin measurement were taken from all patients before hospitalization (T1) and prior to surgery or after ward round (T2). Self- and parents-reports were obtained at T1, T2 as well as at time of discharge from hospital (T3) regarding children's anxiety (STAI), worries and well-being. Clowns evaluated their success in cheering up the child. Health professionals were asked for their acceptance of clowns in hospitals. Results Children in the intervention group had lower anxiety ratings and a higher oxytocin concentration at T2 as compared with T1; the control group showed no changes. Parents rated the well-being of their children higher if their child had clown's contact and were more willing to recommend the hospital. The staff judged the clowns as helpful for patients. Discussion Consistent psychological and physiological results suggest the positive impact of a clown's intervention in hospitalized children. © Georg Thieme Verlag KG Stuttgart · New York.

Rolapitant is a selective and long-acting neurokinin-1 receptor antagonist approved in an oral formulation in combination with other antiemetic agents for the prevention of delayed chemotherapy-induced nausea and vomiting in adults. This was a phase 1 open-label, parallel-group pharmacokinetic and safety study of a single oral dose of 180 mg of rolapitant and its major active metabolite, M19, in subjects with mild and moderate hepatic impairment compared with healthy matched controls. Pharmacokinetics were assessed by a mixed-model analysis of variance of log-transformed values for maximum observed plasma concentration (C max ), observed time at C max (t max ), area under the plasma concentration-time curve (AUC) from time 0 to the time of the last quantifiable concentration (AUC 0-t ), and AUC from time 0 to 120 hours (AUC 0-120 ), with hepatic group as a fixed effect. Mean rolapitant C max , AUC 0-t , and AUC 0-120 were similar in the mild hepatic impairment and healthy control groups. In subjects with moderate hepatic impairment, AUC 0-t was similar and C max was 25% lower than in healthy controls. Mean M19 C max and AUC 0-t were similar in the mild hepatic impairment group and healthy controls, but <20% lower in those with moderate hepatic impairment versus healthy controls. Fraction of unbound rolapitant was comparable in all groups for rolapitant and M19. Rolapitant was well tolerated in all groups, without serious adverse events. Pharmacokinetic differences between healthy subjects and those with mild or moderate hepatic impairment are unlikely to pose a safety risk and do not warrant predefined dosage adjustment in the presence of hepatic impairment. © 2018, The American College of Clinical Pharmacology.

To investigate the effects of dietary zinc (Zn) on small intestinal mucosal epithelium, 6-month-old male Bama miniature pigs were randomly allocated into three groups and treated with three levels of Zn (Control, T1, and T2 diet supplemented with 0, 50, and 1500mg/kg Zn, respectively, as zinc sulfate) for 38days. The samples of small intestine tissues, serum, and feces were collected. The results showed that Zn concentrations of small intestine in the T2 group were higher than those in the control and T1 groups (p<0.05). In the T2 group, the pharmacological dose of dietary Zn treatment caused marked damage to the small intestinal epithelium. The expression of Bax, cleaved caspase-3, and caspase-8 were increased in the duodenum and the jejunum of the T2 group (p<0.05). The mRNA transcript levels of BAX, CYCS and CASP3 genes were upregulated in the duodenum and the jejunum of the T2 group. We concluded that a diet with a pharmacological dose of Zn increased the accumulation of Zn and the expression of Bax, cleaved caspase-3, and caspase-8, which might activate the apoptosis and lead to the marked injury of porcine small intestinal epithelium.

Conjugated linoleic acid (CLA) isomers have high health amelioration potential and hence it is of great interest to increase the CLA content in dairy products. The present study was conducted to investigate the effect of administration of high CLA producing Butyrivibrio fibrisolvens In-1 on fatty acid composition of milk and rumen fluid in lactating goats. Four groups (n = 5) of lactating goats were assigned the following treatments: Control (C) (basal diet); T1 (basal diet + linoleic acid source), T2 (basal diet + suspension of Butyrivibrio fibrisolvens In-1, 10(9) CFU head(-1)) and T3 (basal diet + linoleic acid source + suspension of Butyrivibrio fibrisolvens In-1, 10(9) CFU head(-1)). Rumen liquor and milk samples were collected on days 0, 15, 30, 60 and 90 of the experiment and linoleic isomerase enzyme (LA-I) activity and fatty acid profiles were elucidated. Major effects of treatments were seen on day 30 of the experiment. Total CLA content of rumen fluid increased (P < 0.05) by 218.72, 182.26 and 304% whereas total saturated fatty acid (SFA) content was lowered (P < 0.05) by 6.1, 4.44 and 9.55% in T1, T2 and T3, respectively, as compared to control. Vaccenic acid in groups T2 and T3 increased (P < 0.05) by 66.67% and 105.7% as compared to control. In milk, total CLA increased by 2.03, 1.61 and 0.61 folds in T3, T2 and T1, respectively. Total monounsaturated fatty acid and polyunsaturated fatty acid content increased (P < 0.05) in group T3 by 14.15 and 37.44%, respectively. Results of the present study indicated that administration of B. fibrisolvens In-1 along with a linoleic acid (LA) source is a useful strategy to alter the biohydrogenation pattern in the rumen that subsequently decreased SFA content while increased CLA and unsaturated fatty acids in ruminant's milk. © 2015 Society of Chemical Industry.

Thyroid hormone (TH) abnormalities are common in patients with diabetes mellitus (DM). These thyroid hormone abnormalities have been associated with inflammatory activity in several conditions but this link remains unclear in DM. We assessed the influence of subclinical inflammation in TH metabolism in euthyroid diabetic patients. Cross-sectional study involving 258 subjects divided in 4 groups: 70 patients with T2DM and 55 patients with T1DM and two control groups of 70 and 63 non-diabetic individuals, respectively. Groups were paired by age, sex, and body mass index (BMI). We evaluated the association between clinical and hormonal variables [thyrotropin, reverse T3 (rT3), total and free thyroxine (T4), and triiodothyronine (T3)] with the inflammation markers C-reactive protein (hs-CRP), serum amyloid A (SAA), and interleukin-6 (IL-6). Serum T3 and free T3 were lower in patients with diabetes (all P < 0.001) compared to the control groups. Interleukin-6 showed positive correlations with rT3 in both groups (P < 0.05). IL-6 was independently associated to FT3/rT3 (B = -0.193; 95% CI -0.31; -0.076; P = 0.002) and FT4/rT3 (B = -0.107; 95% CI -0.207; -0.006; P = 0.039) in the T1DM group. In the T2DM group, SAA (B = 0.18; 95% CI 0.089; 0.271; P < 0.001) and hs-CRP (B = -0.069; 95% CI -0.132; -0.007; P = 0.03) predicted FT3 levels. SAA (B = -0.16; 95% CI -0.26; -0.061; P = 0.002) and IL6 (B = 0.123; 95% CI 0.005; 0.241; P = 0.041) were related to FT4/FT3. In DM, differences in TH levels compared to non-diabetic individuals were related to increased subclinical inflammatory activity and BMI. Altered deiodinase activity was probably involved. These findings were independent of sex, age, BMI, and HbA1c levels.

Several longitudinal studies and meta-analytic reviews have demonstrated that exposure to violent media is linked to aggression over time. However, evidence on effective interventions to reduce the use of violent media and promote critical viewing skills is limited. The current study examined the efficacy of an intervention designed to reduce the use of media violence and aggression in adolescence, covering a total period of about 12 months. A sample of 683 7th and 8th graders in Germany (50.1% girls) were assigned to two conditions: a 5-week intervention and a no-intervention control group. Measures of exposure to media violence and aggressive behavior were obtained about 3 months prior to the intervention (T1) and about 7 months post-intervention (T2). The intervention group showed a significantly larger decrease in the use of violent media from T1 to T2 than the control group. Participants in the intervention group also scored significantly lower on self-reported aggressive behavior (physical aggression and relational aggression) at T2 than those in the control group, but the effect was limited to those with high levels of initial aggression. This effect was mediated by an intervention-induced decrease in the normative acceptance of aggression. No gender differences in program efficacy were found. The results show that a 5-week school-based intervention can produce changes in the use of media violence, aggressive norms, and behaviors sustained over several months.

Earlier studies aimed at defining protective immunity induced by Mycobacterium bovis BCG immunization have largely focused on the induction of antituberculosis CD4+ and CD8+ T cell responses. Here we describe a vaccine consisting of a BCGΔmmaA4 deletion mutant formulated in dimethyl dioctadecyl-ammonium bromide (DDA) with d-(+)-trehalose 6,6′-dibehenate (TDB) (DDA/TDB) adjuvant (A4/Adj) that protected TCRδ−/− mice depleted of CD4+, CD8+, and NK1.1+ T cells against an aerosol challenge with M. tuberculosis. These mice were significantly protected relative to mice immunized with a nonadjuvanted BCGΔmmaA4 (BCG-A4) mutant and nonvaccinated controls at 2 months and 9 months postvaccination. In the absence of all T cells following treatment with anti-Thy1.2 antibody, the immunized mice lost the ability to control the infection. These results indicate that an unconventional T cell population was mediating protection in the absence of CD4+, CD8+, NK1.1+, and TCRγδ T cells and could exhibit memory. Focusing on CD4− CD8− double-negative (DN) T cells, we found that these cells accumulated in the lungs postchallenge significantly more in A4/Adj-immunized mice and induced significantly greater frequencies of pulmonary gamma interferon (IFN-γ)-producing cells than were seen in the nonvaccinated or nonadjuvanted BCG control groups. Moreover, pulmonary DN T cells from the A4/Adj group exhibited significantly higher IFN-γ integrated median fluorescence intensity (iMFI) values than were seen in the control groups. We also showed that enriched DN T cells from mice immunized with A4/Adj could control mycobacterial growth in vitro significantly better than naive whole-spleen cells. These results suggest that formulating BCG in DDA/TDB adjuvant confers superior protection in immunocompromised mice and likely involves the induction of long-lived memory DN T cells. PMID:27226281

Text messages are increasingly being used because of the low cost and the ubiquitous nature of mobile phones to engage patients in self-care behaviors. Self-care is particularly important in achieving treatment outcomes in type 2 diabetes mellitus (T2DM). This study examined the effect of personalized text messages on physical activity, as measured by a pedometer, and clinical outcomes in a diverse population of patients with T2DM. Text to Move (TTM) incorporates physical activity monitoring and coaching to provide automated and personalized text messages to help patients with T2DM achieve their physical activity goals. A total of 126 English- or Spanish-speaking patients with glycated hemoglobin A 1c (HbA 1c ) >7 were enrolled in-person to participate in the study for 6 months and were randomized into either the intervention arm that received the full complement of the intervention or a control arm that received only pedometers. The primary outcome was change in physical activity. We also assessed the effect of the intervention on HbA 1c , weight, and participant engagement. All participants (intervention: n=64; control: n=62) were included in the analyses. The intervention group had significantly higher monthly step counts in the third (risk ratio [RR] 4.89, 95% CI 1.20 to 19.92, P=.03) and fourth (RR 6.88, 95% CI 1.21 to 39.00, P=.03) months of the study compared to the control group. However, over the 6-month follow-up period, monthly step counts did not differ statistically by group (intervention group: 9092 steps; control group: 3722 steps; RR 2.44, 95% CI 0.68 to 8.74, P=.17). HbA 1c decreased by 0.07% (95% CI -0.47 to 0.34, P=.75) in the TTM group compared to the control group. Within groups, HbA 1c decreased significantly from baseline in the TTM group by -0.43% (95% CI -0.75 to -0.12, P=.01), but nonsignificantly in the control group by -0.21% (95% CI -0.49 to 0.06, P=.13). Similar changes were observed for other secondary outcomes. Personalized text messaging can be used to improve outcomes in patients with T2DM by employing optimal patient engagement measures. ©Stephen Agboola, Kamal Jethwani, Lenny Lopez, Meghan Searl, Sandra O’Keefe, Joseph Kvedar.

Background and Aims: Earlier studies have shown that the type of laryngoscope blade influences the degree of hemodynamic response to endotracheal intubation. The aim of the study was to evaluate the hemodynamic response to oral endotracheal intubation with C-MAC laryngoscopy and McCoy laryngoscopy compared to that of Macintosh laryngoscopy in adult patients under general anesthesia. Material and Methods: This is a prospective randomized parallel group study. Ninety American Society of Anesthesiologists I patients were randomly allotted into three groups. Group A – Macintosh laryngoscopy (control group). Group B – laryngoscopy with McCoy laryngoscope. Group C – laryngoscopy with C-MAC video laryngoscope. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were monitored at baseline (just before induction), just before intubation (T0), 1 min (T1), 3 min (T3), 5 min (T5), and 10 min (T10) after intubation. Intergroup comparison of study parameters was done by unpaired sample t-test for normal data and Mann-Whitney U-test for skewed data. For within-group comparison, the repeated measures of ANOVA for normal data and Friedman followed by Wilcoxon signed rank test for skewed data were performed. Results: In C-MAC group, the HR was significantly higher than the Macintosh group at 3 min after intubation, whereas SBP, DBP, and MAP were significantly higher at 1 min. McCoy group showed a similar response compared to Macintosh group at all time intervals. Conclusion: C-MAC video laryngoscope has a comparatively greater hemodynamic response than Macintosh laryngoscope. PMID:28096584

To explore the effect of Progressive Muscle Relaxation (PMR) and Guided Imagery (GI),in reducing anxiety levels among parents of children diagnosed with any type of malignancy receiving active treatment at a Paediatric Oncology Unit in Republic of Cyprus and in Greece. A randomized non-blinded control trial was conducted between April 2012 to October 2013, at two public paediatric hospitals. Fifty four eligible parents of children hospitalized with a malignancy were randomly assigned to the intervention (PMR and GI) (n = 29) and a control group (n = 25). The study evaluated the changes in anxiety levels(HAM-A) and mood changes(POMSb). There was a statistically significant difference in the mean scores of the subjects in the intervention group in HAM-A scale between the T0 (14.67 ± 9.93) and T1 (11.70 ± 8.15) measurements (p = 0.008) compared to the control group in which a borderline difference (16.00 ± 11.52 vs 13.33 ± 8.38) was found (p = 0.066). The effect size for the intervention group was low to moderate (0.37). Regarding mood changes, there was a statistically significant difference in tension for parents in the intervention group between T0 and T1 (11.15 ± 5.39 vs 9.78 ± 4.26), (p = 0.027). Furthermore, the parents in the intervention group were significantly less sad following the intervention (T1) (2.81 ± 1.07 vs 2.19 ± 1.21), (p = 0.001), and felt significantly less tense (2.93 ± 0.91 vs 2.26 ± 0.90), (p = 0.001) and anxiety (2.63 ± 1.21 vs 2.19 ± 1.07), (p = 0.031) compared to those in the control group. These findings provided evidence on the positive effect of the combination of PMR and GI in reducing anxiety and improving mood states in parents of children with malignancy.

Lee, Seul Gi; Shin, Yun Hee

2016-04-01

This study was done to verify effects of a self-directed feedback practice using smartphone videos on nursing students' basic nursing skills, confidence in performance and learning satisfaction. In this study an experimental study with a post-test only control group design was used. Twenty-nine students were assigned to the experimental group and 29 to the control group. Experimental treatment was exchanging feedback on deficiencies through smartphone recorded videos of nursing practice process taken by peers during self-directed practice. Basic nursing skills scores were higher for all items in the experimental group compared to the control group, and differences were statistically significant ["Measuring vital signs" (t=-2.10, p=.039); "Wearing protective equipment when entering and exiting the quarantine room and the management of waste materials" (t=-4.74, p<.001) "Gavage tube feeding" (t=-2.70, p=.009)]. Confidence in performance was higher in the experimental group compared to the control group, but the differences were not statistically significant. However, after the complete practice, there was a statistically significant difference in overall performance confidence (t=-3.07. p=.003). Learning satisfaction was higher in the experimental group compared to the control group, but the difference was not statistically significant (t=-1.67, p=.100). Results of this study indicate that self-directed feedback practice using smartphone videos can improve basic nursing skills. The significance is that it can help nursing students gain confidence in their nursing skills for the future through improvement of basic nursing skills and performance of quality care, thus providing patients with safer care.

The study covers development and evaluation of an innovative counselling aid in an intervention study. The main purpose of the study was to establish whether improvements in nutrition and physical activity behaviour according to standard recommendations can be demonstrated. OPTIMAHL 60plus is a quasi-experimental study in which participants were assigned in clusters to an intervention or control group. The study was conducted in low socio-economic-status districts in Bremen, Germany. 423 elderly participated at baseline and 369 after 3 months intervention. Face-to-face interviews (24-h recall and frequency questionnaire) were conducted at T0 and T1. χ (2)-tests, sign-test and logistic regression were used for statistical analyses. No significant differences could be shown when comparing the intervention versus control group at T1. Significant changes from T0 to T1 in the intervention group were identified for daily fruit and vegetable (χ (2)-test, p = 0.04), and for weekly fish consumption (χ (2)-test, p = 0.04). However, similar results could also be shown for the control group. A practical counselling aid for elderly was developed and evaluated. Changes in the health behaviour of elderly were identified, but effects could not be clearly traced to the intervention.

To study the effects of intraoperative dexmedetomidine on the intraocular pressure (IOP) in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALRP) under propofol-remifentanil anesthesia. Double-blind, randomized controlled trial. Operating room. Forty consenting male patients aged ≥20 to <80 years with American Society of Anesthesiologists physical status classes I and II. The patients were randomly assigned to either dexmedetomidine (DEX) (n = 20) or control (n = 20) group. Anesthesia was induced and maintained using propofol, remifentanil, and rocuronium. In the dexmedetomidine group, dexmedetomidine was administered at 0.4 μg/kg/h immediately after anesthesia induction until the end of the surgery, whereas normal saline was administered as placebo in the control group. IOP was measured using a rebound tonometer. Time points of measuring IOP were as follows: T1: before anesthesia induction, T2: 5 min after intubation, T3: 60 min after placing patient in the Trendelenburg position, T4: 120 min after placing patient in the Trendelenburg position, T5: 180 min after placing patient in the Trendelenburg position, T6: 5 min after placing patient in a horizontal position, T7: 5 min after extubation, and T8: 30 min after extubation. A linear mixed model analysis demonstrated a significant intergroup difference in IOP over time and during pneumoperitoneum in the steep Trendelenburg position. IOP at T5 was significantly lower in the dexmedetomidine group than in the control group even after post-hoc analysis in the steep Trendelenburg position periods with Bonferroni correction. Dexmedetomidine combined with propofol decreases IOP in the steep Trendelenburg position during RALRP. Copyright © 2018 Elsevier Inc. All rights reserved.

To investigate the inhibitory effects of electrical stimulation of sacral dorsal root ganglion (DRG) on bladder activity under non-nociceptive and nociceptive bladder conditions in cats. 12 cats were divided into non-nociceptive and nociceptive groups. Saline was used to distend the bladder and induce non-nociceptive bladder activity, while acetic acid (AA, 0.25%) was used to induce nociceptive bladder overactivity, S1 or S2 DRG stimulation was applied via a pair of hook electrodes placed in the right S1 and S2 DRG. In both non-nociceptive and nociceptive groups, stimulation at 3 and 5 Hz significantly increased bladder capacity (BC) and no significantly different between the two frequencies. In non-nociceptive group, S1 DRG stimulation at 3 Hz was as effective (increasing BC to 139.7 ± 5.6 and 166.9 ± 12.21% of control at 1T and 3/2T, respectively) as S2 DRG stimulation (increases BC to 129.2 ± 5.6 and 160.5 ± 13.3% of control). In nociceptive group, AA reduced the BC to 62.6 ± 11.7% of saline control. S1 DRG stimulation at 3 Hz was also as effective (increasing BC to 54.9 ± 5.5 and 61.9 ± 6.0% of saline control at 1T and 3/2T, respectively) as S2 DRG stimulation (increases BC to 58.3 ± 3.7 and 65.6 ± 3.7% of control). This study showed the effective inhibition on bladder activity under both non-nociceptive and nociceptive conditions, suggesting the possibility of sacral DRG stimulation to treat bladder overactivity.

Malaria is highly endemic in Yunnan Province, China, with the incidence of malaria being highest along the Sino-Burmese border. The aim of our study was to determine whether genetic polymorphisms are associated with the prevalence of malaria among Chinese residents of the Sino-Burmese border region. Fourteen otherwise healthy people with glucose-6-phosphate dehydrogenase (G6PD) deficiency, 50 malaria patients, and 67 healthy control subjects were included in our cross-sectional study. We analyzed the frequency of the G3093T and T520C single-nucleotide polymorphisms (SNPs) of CR1. Logistic regression was used to calculate the prevalence odds ratio (POR) and 95% confidence interval (CI) of malaria for the T520C SNP of CR1 and SNPs of G6PD, IL-4, IL-4R, IL-1A, NOS, CD40LG, TNF, and LUC7L. The frequency of the 3093T/3093T genotype of CR1 in the malaria group (0.16) was significantly higher than that in the control group (0.045, P < 0.05), and significantly lower than that in the G6PD deficiency group (0.43, P < 0.01). The frequency of the 520T/520T genotype of CR1 was significantly higher in the malaria patients (0.78) than that in the control group (0.67, P < 0.05) and G6PD-deficiency group (0.36, P < 0.05). The T allele of the T520C variant of CR1 was significantly associated with the prevalence of malaria (POR: 1.460; 95% CI: 0.703-3.034). Polymorphisms of G6PD did not significantly influence the prevalence malaria (P > 0.05). A GTGTGTC haplotype consisting of IL-1A (rs17561), IL-4 (rs2243250), TNF (rs1800750), IL-4R (rs1805015), NOS (rs8078340), CD40LG (rs1126535), and LUC7L (rs1211375) was significantly associated with the prevalence of malaria (POR: 1.822, 95% CI: 0.998-3.324). The 3093G/3093G and 520T/520T genotypes are the predominant genetic variants of CR1 among Chinese residents near the Sino-Burmese border, and the T allele of T520C is associated with the prevalence of malaria in this region. Although G6PD deficiency does not protect against malaria, it may diminish the association between malaria and the CR1 polymorphisms in this population. The GTGTGTC haplotype is also associated with the prevalence of malaria in this region.

A role for γδ T cells in protection against mycobacterial infections including Johne's disease (JD) has been suggested. In neonatal calves where the risk to infection with Mycobacterium avium subsp. paratuberculosis (MAP) is high, the majority of circulating CD3 + lymphocytes are γδ TCR + . Bovine γδ T cells are divided into two major subsets based on the surface expression of workshop cluster 1 (WC1). The WC1 + subset, the predominant subset in periphery, is further divided into WC1.1 + and WC1.2 + subpopulations. The ability of γδ T cells to produce IFN-γ prior to CD4 + αβ T cell activation could be crucial to the outcome of MAP infection. In the current study, cattle were naturally infected with MAP and were classified as either in the subclinical or clinical stage of infection. Compared to the control non-infected group, γδ T cell frequency in circulating lymphocytes was significantly lower in the clinical group. The observed decline in frequency was restricted to the WC1.2 + subset, and was not associated with preferential migration to infection sites (distal-ileum). γδ T cells proliferated significantly in recall responses to stimulation with purified protein derivative from MAP (PPD-J) only in subclinically infected cattle. These responses were a heterogeneous mixture of WC1.1 and WC1.2 subsets. Proliferation and IFN-γ production by the WC1.1 + γδ T cell subset was significantly higher in the subclinical group compared to the control and clinical groups. Our data indicates differences in MAP-specific ex-vivo responses of peripheral WC1 + γδ T cells of cattle with the subclinical or clinical form of JD. Copyright © 2017 Elsevier B.V.

INTRODUCTION—Germline mutations in E-cadherin (CDH1) have been reported in families with early onset, diffuse gastric cancer. More recently, mutations in CDH1 have been described in colorectal cancer cell lines.
AIMS—We have investigated if germline mutations in CDH1 occur among different groups of Korean gastric and colorectal cancer patients, with and without a positive family history.
METHODS—We studied 131 patients and 168 normal controls (88 Korean and 80 non-Korean). Patients were divided into five groups: group I, 20 gastric cancer patients with a family history; group II, 26 colorectal cancer patients with a family history of gastric cancer (those from familial adenomatous polyposis (FAP) and hereditary non-polyposis colorectal cancer (HNPCC) kindred were excluded); group III, 16 HNPCC patients without identified germline mutations in hMLH1 and hMSH2; group IV, 35 gastric cancer patients without a family history; and group V, 34 colorectal cancer patients without a family history. Polymerase chain reaction, single strand conformational polymorphism analysis, direct sequencing, and genotyping for identified variants were performed.
RESULTS—Several germline changes in CDH1 were found. In addition to previously described polymorphisms, we found three novel changes, two of which were missense changes (T340A and L599V). T340A was present in one patient in group III and one in group V. L599V was present in one patient in group II, in two in group III, and in one in group IV. T340A was not found in normal controls while L599V was present in two of 88 Korean controls. Patients with these variants may appear to have a tendency to early onset cancer with a positive family history, although differences in frequencies did not reach statistical significance. Genotyping results suggest that these variants might have a common origin, particularly T340A.
CONCLUSION—We have described two new missense germline variants in CDH1 in various groups of Korean gastrointestinal cancer patients. Further work is required to assess if these variants increase the risk of gastrointestinal cancer.

The aim of this paper was to evaluate the effects of a 12-weeks combined aerobic-resistance exercise therapy on fatigue and isokinetic muscle strength, glycemic control and health-related quality of life (HRQoL) in moderately affected type 2 diabetes (T2DM) patients. A randomized controlled trial design was employed. Forty-three T2DM patients were assigned to an exercise group (N.=22), performing 3 weekly sessions of 60 minutes of combined aerobic-resistance exercise for 12-weeks; or a no exercise control group (N.=21). Both groups were evaluated at a baseline and after 12-weeks of exercise therapy for: 1) muscle strength and fatigue by isokinetic dynamometry; 2) plasma glycated hemoglobin A1C (HbA1C); and 3) HRQoL utilizing the SF-36 questionnaire. The exercise therapy led to improvements in muscle fatigue in knee extensors (-55%) and increased muscle strength in knee flexors and extensors (+15 to +30%), while HbA1C decreased (-18%). In addition, the exercising patients showed sizeable improvements in HRQoL: physical function (+53%), vitality (+21%) and mental health (+40%). Twelve-weeks of combined aerobic-resistance exercise was highly effective to improve muscle strength and fatigue, glycemic control and several aspects of HRQoL in T2DM patients. These data encourage the use of aerobic and resistance exercise in the good clinical care of T2DM.

2015-03-01

To investigate the short-term effects of the asymmetric rapid maxillary (ARME) appliance on the vertical, sagittal, and transverse planes in patients with true unilateral posterior crossbite. Subjects were divided into two groups. The treatment group was comprised of 21 patients with unilateral posterior crossbite (mean age  =  13.3 ± 2.1 years). Members of this group were treated with the ARME appliance. The control group was comprised of 17 patients with Angle Class I who were kept under observation (mean age  =  12.3 ± 0.8 years). Lateral and frontal cephalograms were taken before the expansion (T1), immediately after expansion (T2), and at postexpansion retention (T3) in the treatment group and at preobservation (T1) and postobservation (T2) in the control group. A total of 34 measurements were assessed on cephalograms. For statistical analysis, the Wilcoxon test and analysis of covariance were used. The ARME appliance produced significant increases in nasal, maxillary base, upper arch, and lower arch dimensions (P < .01) and a clockwise rotation of the occlusal plane (P  =  .001). The ARME appliance created asymmetric increments in the transversal dimensions of the nose, maxilla, and upper arch in the short term. Asymmetric expansion therapy for subjects with unilateral maxillary deficiency may provide satisfactory outcomes in adolescents, with the exception of mandibular arch expansion. The triangular pattern of expansion caused clockwise rotation of the mandible and the occlusal plane and produced significant alterations in the vertical facial dimensions, whereas it created no displacement in maxilla in the sagittal plane.

Background To study gradient recalled echo (GRE) T2*-weighted imaging (T2*WI) for normal pancreas and acute pancreatitis (AP). Methods Fifty-one patients without any pancreatic disorders (control group) and 117 patients with AP were recruited. T2* values derived from T2*WI of the pancreas were measured for the two groups. The severity of AP was graded by the magnetic resonance severity index (MRSI) and the Acute Physiology and Chronic Healthy Evaluation II (APACHE II) scoring system. Logistic regression was used to analyze the relationship between the T2* values and AP severity. The usefulness of the T2* value for diagnosing AP and the relationship between the T2* values and the severity of AP were analyzed. Results On GRE-T2*WI, the normal pancreas showed a well-marinated and consistently homogeneous isointensity. Edematous AP, as well as the non-necrotic area in necrotizing AP, showed ill-defined but homogeneous signal intensity. AP with pancreatic hemorrhage showed a decreased T2* value and a signal loss on the signal decay curve. The T2* value of pancreas in the AP group was higher than that of the control group (t=−8.20, P<0.05). The T2* value tended to increase along with the increase in MRSI scores but not with the APACHE II scores (P>0.05). AP was associated with a one standard deviation increment in the T2* value (OR =1.37; 95% CI: 1.216–1.532). Conclusions T2*WI demonstrates a few characteristics of the normal pancreas and AP, which could potentially be helpful for detecting hemorrhage, and contributes to diagnosing AP and its severity.

Although it is recognized that caring for a child with Type 1 diabetes (T1D) is stressful for parents, few interventions have been developed and tested for this population. The aim of this study was to compare a group educational intervention for parents of children with T1D to a coping skills training intervention. Parents of children with T1D were randomized to the group educational (n = 106) or coping skills training (n = 75) conditions. Parents completed measures of family conflict, responsibility for treatment, coping, and quality of life at baseline and at 3, 6, and 12 months postintervention. Clinical data (i.e., HbA1c) were collected from children's medical records preintervention and postintervention. There were no significant treatment effects 12 months postintervention, but parents in both groups reported improved coping (p < .001), less responsibility for treatment management (p < .001), and improved quality of life (p = .005). While children's metabolic control worsened over time, mean values at 12 months were still within the recommended levels in this well-controlled sample (HbA1c <8%). Group-based interventions for parents of children with T1D may lessen the impact of treatment management, improving coping and quality of life.

Possible interactions between selenium and iodine metabolism were investigated in 7- to 16-year-old children with goiter (n = 136) living in southeastern Poland in iodine-deficient areas influenced by a sulfur industry. The Se-iodine interactions in these children were compared to the interactions in children from outside of that region (n = 38). Blood selenium (BSe) concentration and plasma glutathione peroxidase activity were much lower in the study group (64.1 +/- 15.7 microg/L; 111.0 +/- 27.6 U/L) than in the control group (85.3 +/- 19.6 microg/L; 182.4 +/- 35.6 U/L). Almost all of the data [plasma thyroid-stimulating hormone (TSH) concentration, plasma free thyroxine (fT(4)) concentration] fell within the reference limits. There was no statistically significant difference between the control and the study groups with respect to fT(4) and TSH. However, statistically significant differences of fT(4) and TSH in the study group were revealed between females belonging to the lower (n = 21; fT(4), 16.1 +/- 3.3 pmol/L; TSH, 1.83 +/- 1.05 mU/L) and upper Se quartiles (n = 24; fT(4), 14.5 +/- 2.2 pmol/L; TSH, 1. 26 +/- 0.90 mU/L), p < 0.05. Neither group differed in iodine in urine concentration, age, and body mass index. The difference in fT(4) concentrations can be attributed to an Se deficiency. The relationship exists only for females, which suggests a sex-linked hormonal response to concomitant Se and iodine deficiencies. Images Figure 1 Figure 2 PMID:10620526

Experience with the use of real-time continuous glucose monitoring systems (RT-CGMS) in teenagers with type 1 diabetes mellitus (T1DM) is limited. We aimed to assess the possibility of glycaemic control improvement and to characterize the group of adolescents, who may gain long-term benefits from the use of the RT-CGMS. Forty T1DM patients, aged 14.6 ± 2.1 years, with diabetes duration 7.4 ± 3.6 years and initial HbA₁c 9.3 ± 1.5% were recruited. The analysis was based on one-month glucose sensors use, combined with the thorough family support. Patients were analysed in groups according to baseline HbA₁c: below and above 7.5%, and 10.0%. Comparison between patients with or without improvement in HbA₁c after 3-month follow-up was also performed. Patients' satisfaction based on the questionnaire was assessed. HbA₁c level in entire study group decreased after three months, from 9.3 ± 1.0% to 8.8 ± 1.6% (P<0.001). In the group with HbA1c improvement, reduction was the highest: 9.0 ± 1.3% vs. 8.0 ± 1.2% (P<0.001). Only the group with initial HbA₁c>10% did not achieve significant improvement: 11.2 ± 0.5% vs. 10.9 ± 1.1 (P=0.06). In satisfaction questionnaire the lowest scores (negative opinion) were reported by group of patients with initial HbA₁c above 10%, while the highest scores (positive opinion) were found in the group with improvement of HbA₁c after 3 month follow-up. Short-term use of CGMS RT, united with satisfaction questionnaire, performed in poorly controlled teenagers with T1DM, can be useful in defining the group of young patients, who can benefit from long-term CGMS RT use in metabolic control improvement.

Non insulin dependent diabetes mellitus is the most common type of diabetes. Genetic factors, lipid profiles, hypertension are potential risk factors for diabetes mellitus. Adenosine binding cassette transporter proteins 1 (ABCA1) plays a role in cholesterol metabolism, especially high density lipoprotein (HDL-cholesterol). There are multiple mechanisms by which HDL-cholesterol can be atheroprotective, it is clear that the relative activity of ABCA1 plays a major role. We aimed to investigate association of ABCA1 C69T gene polymorphism with lipid levels in Turkish type 2 diabetic patients. After isolation of DNA by ethanol precipitation we determined ABCA1 gene polymorphism by using polimerase chain reaction--restriction fragment lenght polymorphism (PCR-RFLP) method in 107 type 2 diabetic patients and 50 healthy controls. We have observed that the frequency of TT genotype is significantly higher in healthy controls compared to patients (14% vs. 3%; P = 0.008). Also frequency of T allele was higher in controls than in patients (34% vs. 21%; P = 0.020; OR (95% CI) = 0.52 (0.30-0.88)). There was no association of lipid levels and ABCA1 C69T polymorphism subgroups. We have found significantly higher frequency of both T allele and genotype in control group when compared to patients that made us think that T allele may be a protective factor against diabetes mellitus. But, we could not find a relationship between genotypes and lipid concentrations in our two groups. Larger studies will help us to understand the relationship between ABCA1 C69T genotype and lipid parameters in diabetes mellitus.

Studies on risk preferences have long been of great concern and have examined the neural basis underlying risk-based decision making. However, studies using conventional transcranial direct current stimulation (tDCS) revealed that bilateral stimulation could change risk propensity with limited evidence of precisely focalized unilateral high-definition transcranial direct current stimulation (HD-tDCS). The aim of this experiment was to investigate the effect of HD-tDCS focalizing the left dorsal lateral prefrontal cortex (DLPFC) on risk-taking behavior during the Balloon Analogue Risk Task (BART). This study was designed as a between-subject, single-blind, sham-controlled experiment. University students were randomly assigned to three groups: the anodal group (F3 anode, AF3, F1, F5, FC3 returned), the cathodal group (F3 cathodal, AF3, F1, F5, FC3 returned) and the sham group. Subsequently, 1.5-mA 20-min HD-tDCS was applied during the BART, and the Positive Affect and Negative Affect Scale (PANAS), the Sensation Seeking Scale-5 (SSS-5), and the Behavioral Inhibition System and Behavioral Approach System scale (BIS/BAS) were measured as control variables. The cathodal group earned less total money than the sham group, and no significant difference was observed between the anodal group and the sham group. These results showed that, to some extent, focalized unilateral cathodal HD-tDCS on left DLPFC could change performance during risky tasks and diminish risky decision making. Further studies are needed to investigate the dose effect and electrode distribution of HD-tDCS during risky tasks and examine synchronous brain activity to show the neural basis.

Self-monitoring of blood glucose (SMBG) has been recommended as a useful tool for improving glycemic control, but is still an underutilized strategy and most diabetic patients are not aware of the actions that must be taken in response to its results and do not adjust their treatment. The purpose of this study was to evaluate the effectiveness and safety of an educational program for insulin self-adjustment based on SMBG in poorly controlled patients with type 2 diabetes (T2DM). A prospective, randomized, controlled 12-week intervention study was conducted on poorly controlled insulin-requiring patients with T2DM. Twenty-three subjects were randomized to two educational programs: a 2-week basic program with guidance about SMBG and types and techniques of insulin administration (group A, n = 12) and a 6-week program including the basic one and additional instructions about self-titration of insulin doses according to a specific protocol (group B, n = 11). Patients were reviewed after 12 weeks and baseline to endpoint changes in glycated hemoglobin (A1C), insulin doses, body weight and incidence of hypoglycemia were compared by paired and independent Student t-tests. After 12 weeks, there was a significant reduction in A1C only in group B, but group comparison showed no significant difference (p = 0.051). A higher percentage of subjects in group B achieved an A1C near the treatment target (<7.5%) than in group A. Daily insulin dose increased non-significantly in the two groups and there was no significant difference in the incidence of hypoglycemia or body weight changes between groups. Training for self-titrating insulin doses combined with structured SMBG can safely improve glycemic control in poorly controlled insulin-treated T2DM patients. This strategy may facilitate effective insulin therapy in routine medical practice, compensating for any reluctance on the part of physicians to optimize insulin therapy and thus to improve the achievement of recommended targets of diabetes care.

Thermal manipulation during embryogenesis was previously reported to decrease the occurrence of ascites and to potentially improve cold tolerance of broilers. The objective of our study was to explore the effects of the interaction of cold incubation temperatures and cool ambient temperatures until 21 d of age on performance and body temperature. Ross 308 eggs were incubated either under control conditions I0 (37.6°C) or with cyclic cold stimulations I1 (6 h/d at 36.6°C from d 10 to 18 of incubation) or with 2 cold stimulations I2 (30 min at 15°C) at d 18 and 19 of incubation. These treatments were followed by individual rearing and postnatal exposure to either standard rearing temperature T0 (from 33°C at hatching to 21°C at d 21) or continuously lower temperature T2 (from 28°C at hatching to 21°C at d 21) or exposure to cyclically lower temperature T1 (with circadian temperature oscillations). Treatments I1 and I2 did not significantly alter hatchability compared to control incubation (with 94.8, 95.1, and 92.3%, respectively), or hatching BW and overall chick quality. Hatching body temperature (Tb) was 0.5 and 0.3°C higher in I1 than in I0 and I2 groups, respectively (P = 0.007). A doubled occurrence of health problems was observed with T2 condition, regardless of incubation or sex. At d 3, BW was 2% lower with treatment I1 than with I0 and I2 and was 3% higher in T1 and T2 groups than in T0, but these effects disappeared with age. Group T2 presented a 5% higher feed intake than the control group T0 between 3 and 21 d of age (P = 0.025). Feed conversion ratio (FCR) was affected by experimental conditions (P < 0.001), with low FCR values obtained with I2 incubation in control or cyclically cold postnatal conditions. Maximal FCR values were observed in the continuously cold postnatal conditions, in males submitted to control incubation and in females submitted to I1 incubation, revealing sex-dependent effects of the treatments on performance. © The Author 2017.

Objectives: In the absence of large, prospective, placebo-controlled studies of longer duration, substantial evidence regarding the safety and risk of testosterone (T) therapy (TTh) with regard to cardiovascular (CV) outcomes can only be gleaned from observational studies. To date, there are limited studies comparing the effects of long-term TTh in men with hypogonadism who were treated or remained untreated with T, for obvious reasons. We have established a registry to assess the long-term effectiveness and safety of T in men in a urological setting. Here, we sought to compare the effects of T on a host of parameters considered to contribute to CV risk in treated and untreated men with hypogonadism (control group). Patients and Methods: Observational, prospective, cumulative registry study in 656 men (age: 60.7 ± 7.2 years) with total T levels ≤12.1 nmol/L and symptoms of hypogonadism. In the treatment group, men (n = 360) received parenteral T undecanoate (TU) 1000 mg/12 weeks following an initial 6-week interval for up to 10 years. Men (n = 296) who had opted against TTh served as controls. Median follow-up in both groups was 7 years. Measurements were taken at least twice a year, and 8-year data were analyzed. Mean changes over time between the 2 groups were compared by means of a mixed-effects model for repeated measures, with a random effect for intercept and fixed effects for time, group, and their interaction. To account for baseline differences between the 2 groups, changes were adjusted for age, weight, waist circumference, fasting glucose, blood pressure, and lipids. Results: There were 2 deaths in the T-treated group, none was related to CV events. There were 21 deaths in the untreated (control) group, 19 of which were related to CV events. The incidence of death in 10 patient-years was 0.1145 in the control group (95% confidence interval [CI]: 0.0746-0.1756; P < .000) and 0.0092 in the T-treated group (95% CI: 0.0023-0.0368; P < .000); the estimated difference between groups was 0.0804 (95% CI: 0.0189-0.3431; P < .001). The estimated reduction in mortality for the T-group was between 66% and 92%. There were also 30 nonfatal strokes and 26 nonfatal myocardial infarctions in the control group and none in the T-treated group. Conclusion: Long-term TU was well tolerated with excellent adherence suggesting a high level of patient satisfaction. Mortality related to CV disease was significantly reduced in the T-group.

Hand hygiene is a key component of infection control in healthcare. WHO recommends that healthcare workers perform six specific poses during each hand hygiene action. SureWash (Glanta Ltd, Dublin, Ireland) is a novel device that uses video-measurement technology and immediate feedback to teach this technique. We assessed the impact of self-directed SureWash use on healthcare worker hand hygiene technique and evaluated the device's diagnostic capacity. A controlled before-after study: subjects in Group A were exposed to the SureWash for four weeks followed by Group B for 12 weeks. Each subject's hand hygiene technique was assessed by blinded observers at baseline (T0) and following intervention periods (T1 and T2). Primary outcome was performance of a complete hand hygiene action, requiring all six poses during an action lasting ≥20 seconds. The number of poses per hand hygiene action (maximum 6) was assessed in a post-hoc analysis. SureWash's diagnostic capacity compared to human observers was assessed using ROC curve analysis. Thirty-four and 29 healthcare workers were recruited to groups A and B, respectively. No participants performed a complete action at baseline. At T1, one Group A participant and no Group B participants performed a complete action. At baseline, the median number of poses performed per action was 2.0 and 1.0 in Groups A and B, respectively (p = 0.12). At T1, the number of poses per action was greater in Group A (post-intervention) than Group B (control): median 3.8 and 2.0, respectively (p<0.001). In Group A, the number of poses performed twelve weeks post-intervention (median 3.0) remained higher than baseline (p<0.001). The area under the ROC curves for the 6 poses ranged from 0.59 to 0.88. While no impact on complete actions was demonstrated, SureWash significantly increased the number of poses per hand hygiene action and demonstrated good diagnostic capacity.

In the Mexican-American population, the prevalence of Type 2 diabetes mellitus (T2DM) is as high as 50% of the population. This randomized controlled clinical trial was designed to elucidate how treatment of periodontal disease affects HbA1c values in this population. One hundred and fifty-four T2DM patients with periodontal disease were enrolled in the study. The test group was treated with scaling and root planing (SRP); the control group received oral hygiene instructions. At baseline and 4-6 weeks after therapy, a complete periodontal examination was performed. Blood was collected at baseline and 4 months later for HbA1c levels. One hundred and twenty-six individuals completed the study. Baseline mean ± SD HbA1c for the test and control groups were 9.0 ± 2.3% and 8.4 ± 2.0% respectively. Non-significant difference in HbA1c reductions (0.6 ± 2.1% and 0.3 ± 1.7%) was found between test and control groups at 4 months. Comparisons of the periodontal clinical parameters between the test and control groups found significant differences with improved results in the test subjects. No statistically significant differences were found in the changes of HbA1c levels between test and control groups. Non-surgical periodontal therapy improved the magnitude of change in periodontal parameters as compared to the control subjects.

The current study was conducted to identify technology for the production of high quality pork, based on the meat consumption habits of consumers. Macsumsuk, a type of kaolinite (a clay mineral), and/or a mixture of herbs (Mori Folium, Sophorae Radix, Glycyrrhizae Radix, Citri Leiocarpae Exocarpium, and Pogostemi Herba) were added to the diets of fattening pigs. Sixty barrow pigs (4 kinds of treatment × 5 pigs/treatment × 3 replicates) were randomly assigned to either the Control (no additives), T1 (3% Macsumsuk), T2 (3% Herb mixtures), or T3 (3% Macsumsuk + 3% Herb mixtures) groups, and were fed the diets for 60 d. Dressed weights were in the order of T1 (93.40±4.68kg) > T2 (91.40±6.52kg) > Control (88.80±1.57kg) > T3 (86.80±2.01kg). Back-fat thickness of the Control animals (23.2±1.03) was significantly greater than that of the various treatment groups (p<0.01). Numeric values representing the carcass yield and quality grade were higher for all the treated groups than the Control group, thought the difference was not statistically significant. Crude fat content was significantly higher in the Control group (2.23±0.34%) than in the treated groups (p<0.05). The addition of both Macsumsuk and herb mixtures into the diets of the pigs significantly reduced cooking loss of the pork compared to the Control (p<0.05). No statistically significant changes were observed in the shear force (average 5.87±0.54 kg/cm2), water holding capacity (average 54.59±3.16%), or CIE values of the pork, whereas cholesterol levels significantly decreased (p<0.01) in those fed Macsumsuk and/or the herb mixtures. No significant changes in fatty acid composition, total saturated fatty acid (SFA), total unsaturated fatty acid (UFA), or UFA/SFA ratios were observed by any of the treatments. In conclusion, the results obtained from this study suggest that the addition of Macsumsuk and/or herb mixtures into the diets of growing and fattening pigs improves the pork quality by reducing cooking loss, decreasing cholesterol content, and enhancing sensory characteristics.

Type 1 diabetes mellitus (T1DM) is characterized by an immunological reaction that is dominated by type-1 T helper (Th1) cells, whereas immunoglobulin E (IgE)-mediated allergies are associated with Th2 cell. According to the Th1/Th2-hypothesis, the immune system is said to either develop into the direction of Th1 or Th2 cells. This would mean that a child developing T1DM is unlikely to develop an IgE-mediated allergy and vice versa. The aim of the study was to investigate the association between the prevalence of T1DM and IgE-mediated allergies. We designed a prospective case control study with 94 children and adolescents with T1DM and 188 age- and sex-matched control children. The basis of our investigations was a questionnaire concerning the family and children's history as to the presence of IgE-mediated allergies. Moreover, the following blood investigations were done: total serum IgE, specific IgE antibodies to major inhalant allergens, and a multiplex cytokine analysis measuring levels of specific cytokines representing either Th1- or Th2- cytokines. Children with T1DM reported the presence of IgE-mediated allergies significantly more often than children of the control group. Children with T1DM had significantly higher tumor necrosis factor alpha (TNFα) levels than healthy controls. Levels of interleukin-2 (IL-2) and IL-6 were higher in the groups of children with the presence of a personal history of allergies, regardless of the presence of T1DM. Our results suggest that T1DM is associated with a higher risk of a self-reported presence of IgE-mediated allergies and that the Th1/Th2-hypothesis may be an oversimplification. © 2015 John Wiley & Sons A/S.

To evaluate the long-term effects of the standard (Class II) Balters bionator in growing patients with Class II malocclusion with mandibular retrusion by using morphometrics (thin-plate spline [TPS] analysis). Twenty-three Class II patients (8 male, 15 female) were treated consecutively with the Balters bionator (bionator group). The sample was evaluated at T0, start of treatment; T1, end of bionator therapy; and T2, long-term observation (including fixed appliances). Mean age at the start of treatment was 10 years 2 months (T0); at posttreatment, 12 years 3 months (T1); and at long-term follow-up, 18 years 2 months (T2). The control group consisted of 22 subjects (11 male, 11 female) with untreated Class II malocclusion. Lateral cephalograms were analyzed at the three time points for all groups. TPS analysis evaluated statistical differences (permutation tests) in the craniofacial shape and size between the bionator and control groups. TPS analysis showed that treatment with the bionator is able to produce favorable mandibular shape changes (forward and downward displacement) that contribute significantly to the correction of the Class II dentoskeletal imbalance. These results are maintained at a long-term observation after completion of growth. The control group showed no statistically significant differences in the correction of Class II malocclusion. This study suggests that bionator treatment of Class II malocclusion produces favorable results over the long term with a combination of skeletal and dentoalveolar shape changes.

This research was conducted to investigate the effect of supplementation of zinc (Zn) and ascorbic acid (AA) in heat-stressed broilers. A total of 160-day-old broiler chicks of approximately the same weight and appearance were divided into four treatment groups (control, T1, T2, and T3). Control group was fed a standard diet without any supplementation. T1 was supplemented with Zn at the rate of 60 mg/kg of feed, T2 was supplemented with 300 mg/kg of feed AA, and T3 was supplemented with combination of Zn and AA. From week 3 to 5, heat stress environment was provided at the rate of 12 h at 25 °C, 3 h at 25 to 34 °C, 6 h at 34 °C, and 3 h at 34 to 25 °C daily. The results revealed that feed intake, body weight and feed conversion ratio (FCR), and weight of thymus, spleen, and bursa of Fabricius improved significantly ( P < 0.05) in T3 compared to the other treatments. Antibody titer against Newcastle disease (ND), infectious bursal disease (IBD), and infectious bronchitis (IB) increased significantly ( P < 0.05) in T2 and T3 groups. However, total leucocytes count, lymphocytes, and monocytes increased ( P < 0.05) in all treated groups compared to control. The results indicated that the supplementation of Zn or AA alone or in combination improved the performance and immune status of broilers reared under heat stress.

To study the characteristics of the peripheral blood lymphocyte subsets in pediatric patients with chronic active EBV (CAEBV) infection. Flow cytometry was used to detect the peripheral blood NK, B, T lymphocyte subsets and the functional, regulatory, naïve, memory and activatory subsets of T lymphocytes in 10 pediatric patients with CAEBV infection, 13 pediatric patients with acute Epstein-Barr virus infection (AEBV) and 12 healthy children in our hospital between March 2004 and April 2008. Compared with AEBV group, the number of white blood cells [3325 x 10(6)/L (median, just the same as the following)], lymphocytes (1078 x 10(6)/L), NK cells (68 x 10(6)/L), B cells (84 x 10(6)/L), total T cells (684 x 10(6)/L), CD4+ T cells (406 x 10(6)/L) and CD8+ T cells (295 x 10(6)/L) in CAEBV patients were lower (P<0.05). The functional subset of the CD4+ T cells in CAEBV group (94.5%) was lower than those of the healthy control group (98.7%) (P<0.05), but was still higher than those of AEBV group (74.0%) (P<0.05). While the functional subset of the CD8+ T cells in CAEBV (40.7%) was not dramatically different from the healthy control group (48.3%), but was still higher than that of AEBV group (21.0%) (P<0.05). Although the regulatory subset in CAEBV group (5.0%) was higher than the health control group (4.6%) (P<0.05), but lower than AEBV group (5.8%) (P<0.05). In CAEBV, the proportion of CD4+/CD8+ naïve T cells (32.3%/37.5%) was lower than that of normal group (58.3%/56.6%) (P<0.05), but the proportion of CD4+/CD8+ effective memory T cells in CAEBV group (23.9%/15.1%) was lower than that in AEBV group (36.5%/69.8%) (P<0.05), while the proportion of CD8+ fake naïve T cells in CAEBV (17.5%) was higher than the other 2 groups (P<0.05). The CD8+ activatory subset in CAEBV group (84.4%/34.0%) was higher than that of the healthy control group (44.1%/16.7%) (P<0.05), but still lower than AEBV group (96%/95%) (P<0.05). There is an imbalance in lymphocyte subsets and disturbance in cellular immunity in CAEBV patients, which may be associated with EBV chronic active infection. Detecting the peripheral haematologic parameters and lymphocyte subsets may be helpful in the diagnosis and the differential diagnosis of CAEBV.

Objective: To evaluate the effects of percutaneous nephrolithotomy (PNL) in the treatment of medullary sponge kidney with calculi. Methods: A total of 77 patients (91 renal units) of medullary sponge kidney with calculi (MSK group) and 77 patients (77 renal units) with common kidney stone (control group) received PNL at Department of Urology in Peking University People's Hospital from September 2006 to February 2016 were analyzed retrospectively. The MSK group included 33 males and 44 females with a mean age of (42.1±13.2) years, the mean stone burden was (3.9±1.8) cm. The control group included 36 males and 41 females with a mean age of (45.3±13.0) years, the mean stone burden was (3.6±1.5) cm. The numbers of tracts, the time of operation, the drop of hemoglobin, the change of creatine, the time of hospitalization, the stone free rate and major complications were compared between the two groups. The measurement data and numeration data were compared with t test and χ(2) test. Results: There were no significant differences in sex, age, preoperative urinary tract infection, stone type, and stone burden between the two groups (all P >0.05). The proportion of bilateral renal calculus in MSK group was higher (18.2% vs . 0, χ(2)=15.400, P =0.000). There were 159 percutaneous channels were established in MSK group while 90 percutaneous channels were established in control group. Compared with the control group, the operation time ((88.1±37.5) minutes vs . (68.5±30.1) minutes, t =3.543, P =0.000) and hospitalization time ((15.1±8.3) days vs . (10.1±3.6) days, t =4.816, P =0.000) were longer, the creatinine level increased ((101.2±62.6) μmol/L vs . (71.3±23.6) μmol/L, t =3.777, P =0.000), the rate of stone free decreased (27.5% vs . 83.1%, χ(2)=51.840, P =0.000) and the rate of complications increased (29.9% vs . 11.7%, χ(2)=8.114, P =0.004) in MSK group. There was no statistically difference in hemoglobin drop ((12.5±13.2) g/L vs . (13.0±10.9) g/L, t =-0.260, P =0.795). Conclusions: Using PNL for patients of MSK with calculi has a lower stone free rate and a higher complications. It is an effective method for patients of MSK with large and complex calculi.

This study was conducted to develop and to test the effects of an educational program for coping with problem situations as a nursing intervention in the diabetic patient. A non-equivalent control group pretest-posttest design was used in this study. Data were collected from January to March, 2002. The subjects of the study consisted of 31 diabetic patients(experimental group: 17 patients, control group: 14 patients). The intervention of an educational program for coping with problem situations was applied to the experimental group for 4 weeks (total 8 hours). Data were collected before the educational program, immediately after and 1 months later and were analyzed with repeated measures ANOVA, t-test, and paired t-test. 1. There was a significant difference in self efficacy between the experimental and control groups (F=13.793, p=0.001). 2. There was a significant difference in self care behavior between the experimental and control groups (F=4.583, p=0.041). 3. There was a significant difference in coping behavior of the problem situation between the experimental and control groups (F=62.018, p=0.000). There was a significant difference according to experimental stages (F=4.546, p=0.015) and interaction between education and experimental stages (F=12.039, p=0.000). 4. There was a significant difference in glycemic control between the experimental and control groups (t=-3.112, p=0.004). These results support that a diabetic educational program for coping with problem situations is effective in promoting and maintaining self efficacy, self care behavior, problem coping behaviors and in improving glycemic control. Thus this program can be recommended as an effective nursing intervention of in-depth education for diabetic patient.

The P.A.R.T.Y. (Prevent Alcohol and Risk-Related Trauma in Youth) program is a 1-day injury awareness and prevention program for youth aged 15 years and older. The goal is to teach adolescents to recognize their injury risks and make informed decisions to reduce them. This study assessed the effectiveness of the P.A.R.T.Y. Program in preventing traumatic injuries during a period of 10 years (1992-2004). P.A.R.T.Y. participants (STUDY) were matched with subjects having the same age, gender, residential area, and initial year in database, who did not attend the P.A.R.T.Y. Program (CONTROL). Data from hospital discharge database, and provincial health claims, were searched to determine the incidence of traumatic injuries in both groups. Statistical comparisons were made for the two groups, gender, calendar year, and before and after the graduating driver licensing system was implemented, using the χ and conditional logistic regression analysis with a p<0.05 considered significant. Of 3,905 P.A.R.T.Y. participants, 1,281 were successfully randomly matched on the above 4 variables with 1,281 controls. The most frequent injury was injury by other or homicide 373 of 2,562 (14.8%). There were fewer traumatic injuries in the STUDY group than in the CONTROL group (43.3% vs. 47.4%; p=0.02; OR, 1.22; 95% CI, 1.03-1.45). This difference was stronger in females (44.4% vs. 49.0%; p=0.04) and before the graduating driver licensing system implementation (60.1% vs. 67.2%; p=0.04). The P.A.R.T.Y. Program effectively reduced the incidence of traumatic injuries among its participants. This effectiveness was stronger among females and before the driver licensing system was implemented.

This study evaluated the associations between depressive symptoms, emotion dysregulation and bulimic symptoms in youth with type 1 diabetes (T1D) in the context of the diagnosis and treatment of T1D. Study participants were 103 youth in 2 distinct groups: newly diagnosed (New) or transitioning to pump therapy (continuous subcutaneous insulin infusion [CSII]; “Pump”), who completed questionnaires regarding symptoms of depression, emotion dysregulation, and bulimia. Glycemic control (A1c), height, weight, and questionnaires were evaluated within 10 days of diagnosis (n = 58) or at education/clinic visit before starting insulin utilizing CSII (n = 45). In the newly diagnosed group, only depression accounted for significant variance in bulimia scores (β = .47, P < .01). For the group with disease treatment experience (Pump), but not for the newly diagnosed group (New), greater depressive symptoms and emotion dysregulation were associated with greater bulimic symptoms. Depressive symptoms and emotion dysregulation, an indicator of poor coping/behavioral control, could help explain adoption of disordered eating behaviors in youth with T1D who are transitioning to pump therapy.

Background Ossification of the nuchal ligament (ONL) caused by chronic injury to the nuchal ligament (NL) is very common in instability-related cervical disorders. Purpose To determine possible correlations between ONL, sagittal alignment, and segmental stability of the cervical spine. Material and Methods Seventy-three patients with cervical spondylotic myelopathy (CSM) and ONL (ONL group) and 118 patients with CSM only (control group) were recruited. Radiographic data included the characteristics of ONL, sagittal alignment and segmental stability, and ossification of the posterior longitudinal ligament (OPLL). We performed comparisons in terms of radiographic parameters between the ONL and control groups. The correlations between ONL size, cervical sagittal alignment, and segmental stability were analyzed. Multivariate logistic regression was used to identify the independent risk factors of the development of ONL. Results C2-C7 sagittal vertical axis (SVA), T1 slope (T1S), T1S minus cervical lordosis (T1S-CL) on the lateral plain, angular displacement (AD), and horizontal displacement (HD) on the dynamic radiograph increased significantly in the ONL group compared with the control group. The size of ONL significantly correlated with C2-C7 SVA, T1S, AD, and HD. The incidence of ONL was higher in patients with OPLL and segmental instability. Cervical instability, sagittal malalignment, and OPLL were independent predictors of the development of ONL through multivariate analysis. Conclusion Patients with ONL are more likely to have abnormal sagittal alignment and instability of the cervical spine. Thus, increased awareness and appreciation of this often-overlooked radiographic finding is warranted during diagnosis and treatment of instability-related cervical pathologies and injuries.

To examine the cross-sectional association between physical activity (PA) and hippocampal volume in middle-aged adults with childhood-onset type 1 diabetes (T1D), and whether hyperglycemia and insulin sensitivity contribute to this relationship. We analyzed neuroimaging and self-reported PA data from 79 adults with T1D from the Pittsburgh Epidemiology of Diabetes Complications Study (mean age 50 years, mean duration 41 years) and 122 similarly aged adults without T1D (mean age 48 years). Linear regression models, controlling for intracranial volume, sex, education, and age, tested associations between PA and gray matter volumes of hippocampi and total brain in the 2 groups. For the T1D group, models further controlled for hyperglycemia and glucose disposal rate, a measure of insulin sensitivity. PA was significantly lower in the T1D than in the non-T1D group (median [interquartile range] 952 kcal [420-2,044] vs 1,614 kcal [588-3,091], respectively). Higher PA was significantly associated with larger hippocampi for T1D, but not for non-T1D (standardized β [ p values] from regression models adjusted for intracranial volume, sex, age, and education: 0.270 [ p < 0.001] and 0.098 [ p = 0.12], respectively). Neither hyperglycemia nor glucose disposal rate substantially modified this association. Relationships between PA and total brain gray matter volume were similar. A cross-sectional association between higher PA and larger hippocampi is already detectable by middle age for these patients with T1D, and it appears robust to chronic hyperglycemia and insulin sensitivity. Proof-of-concept studies should investigate whether increasing PA preserves hippocampal volume and the mechanisms underlying the effects of PA on hippocampal volume. © 2017 American Academy of Neurology.

This study is supposed to investigate the effects of combined epidural and general anesthesia on intraoperative hemodynamic responses, postoperative cellular immunity, and prognosis in patients with gallbladder cancer (GBC). One hundred forty-four GBC patients were selected and randomly divided into the general anesthesia (GA) group and the combined epidural-general anesthesia (CEGA) group. Before anesthesia induction (t0), at intubation (t1), at the beginning of surgery (t2), 5 minutes after pneumoperitoneum (t3), at the end of surgery (t4), after recovery of spontaneous breathing (t5), after regaining consciousness (t6), and after extubation (t7), the heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and the depth of anesthesia (bispectral index [BIS]) were detected. Blood samples were separately collected 30 minutes before anesthesia induction (T1), 2 hours after the beginning of surgery (T2), at the end of surgery (T3), 1 day after surgery (T4), 3 days after surgery (T5). The survival rates of T cell subsets (CD3+, CD4+, CD8+, CD4+/CD8+) and natural killer (NK) cells were determined by flow cytometry. Postoperative nausea and vomiting (PONV), visual analog scale (VAS), and sedation-agitation scale (SAS) were performed to assess postoperative adverse reactions. A 3-year follow-up was conducted. Compared with the GA group, the CEGA group had significant lower SBP values at t5 and t6, lower DBP values at t1, t3, t4, and t5, lower HR values at t1 and t5, and higher BIS values at t4, t5, t6, and t7. No PONV was observed in the CEGA group. In comparison to the GA group, the VAS was markedly increased and survival rates of CD3+, CD4+, and CD4+/CD8+ cells were increased at T2, T3, T4, and T5 in the CEGA group. The 1-year, 2-year, and 3-year survival rates were not evidently different between the CEGA group and the GA group. Our study provides evidence that the combined epidural-general anesthesia might attenuate intraoperative hemodynamic responses and improve postoperative cellular immunity, so that it might be a more available anesthesia method for GBC patients.

In this study, we analyzed single nucleotide polymorphisms (SNP) in urate transporter genes to examine the pathogenesis of gout. We conducted a 1:1-matched case-control study that included 110 patients with acute gout attacks as the patient group and 110 healthy age- and gender-matched subjects as the control group. Clinical parameters were recorded and blood biochemistry tests were conducted for both groups. Multivariate logistic regression analysis was used to analyze the data. Hyperuricemia, hypercholesterolemia, and hypertriglyceridemia were found to be the main risk factors for the onset of gout, with relative risks of 29.2 (P < 0.001), 25.5 (P = 0.003), and 11.2 (P < 0.001). For all detected SNP, rs2231142, located in ABCG2, showed the largest frequency differences for the G/G, G/T, and T/T genotypes between groups: the distribution of these genotypes in the case group was 22, 49, and 26 individuals, respectively, and was 54, 38, and 9 individuals, respectively, in the control group. There was a statistically significant difference between the 2 groups (P < 0.001) and the odds ratio was 7.091 (95% confidence interval = 2.867-17.541). Other SNPs (rs1165196, rs1165205, rs1183201, rs17300741, rs2078267, rs2242206, rs3733591, and rs9358856) showed no significant difference between the groups (P > 0.05). The risk factors of gout were hyperuricemia, hypercholesterolemia, hypertriglyceridemia, and the T/T genotype of the rs2231142 locus in the ABCG2 gene; expression of the G/G genotype may be a protective factor against gout development.

Little is known about quality-of-life (QOL) differences over time between incident ductal carcinoma in situ (DCIS) and early-stage invasive breast cancer (EIBC) cases as compared with same-aged women without breast cancer (controls). We prospectively recruited and interviewed 1096 women (16.8% DCIS, 33.3% EIBC [25.7% Stage I, 7.6% Stage IIA], 49.9% controls; mean age 58; 23.7% non-white) a mean 6.7 weeks (T1), and 6.2 (T2), 12.3 (T3), and 24.4 months (T4) after surgery (patients) or screening mammogram (controls). We tested two hypotheses: (1) DCIS patients would report lower levels of QOL compared with controls but would report similar QOL compared with EIBC patients at baseline; and (2) DCIS patients’ QOL would improve during 2-year follow-up and approach levels similar to that of controls faster than EIBC patients. We tested Hypothesis 1 using separate general linear regression models for each of the eight subscales on the RAND 36-item Health Survey, controlling for variables associated with at least one subscale at T1. Both DCIS and EIBC patients reported lower QOL at T1 than controls on all subscales (each p < .05). We tested Hypothesis 2 using generalized estimating equations to examine change in each QOL subscale over time across the three diagnostic groups adjusting for covariates. By T3, physical functioning, role limitations due to physical problems, energy/fatigue, and general health each differed significantly by diagnostic group at P < 0.05, due to larger differences between EIBC patients and controls; but DCIS patients no longer differed significantly from controls on any of the QOL subscales. At T4, EIBC patients still reported worse physical functioning (P = 0.0001) and general health (P = 0.0017) than controls, possibly due to lingering treatment effects. DCIS patients’ QOL was similar to that of controls two years after diagnosis, but some aspects of EIBC patients’ QOL remained lower. PMID:22484800

Objective Exercise training provides a cornerstone of pulmonary rehabilitation (PR) in COPD-patients. However, the components of the training are not yet fully investigated. We conducted a randomized controlled trial to investigate the effectiveness of a sensory-motoric training (SMT) in comparison to a conventional strength training (KT) according to the physical performance. Patients and Methods: 43 COPD patients were randomized and participated either in the intervention group (SMT = 30 minutes SMT per day) or in the control group (KT = 30 minutes KT per day). The SMT was performed as circuit training with five stations. The primary endpoint was the difference between T1 (start of the PR) and T2 (end of the PR) in 5-Times Sit-to-stand test (5-STST) in the intergroup comparison. Secondary endpoints were the intra- and intergroup comparisons of T1 and T2 in the 6-Minute Walk Test (6-MWT), COPD Assessment Test (CAT), St. George Respiratory Questionnaire (SGRQ), Hospital Anxiety- and Depression Scale (HADS) and in lung function. Results No significant differences were seen in the results of the 5-STST between the groups. Likewise, in the 6-MWT, SGRQ, CAT, HADS and lung function. The intragroup comparison between T1 and T2 showed significant differences in 5-STST, 6-MWT, SGRQ, CAT and HADS in both groups. The differences in lung function were not significantly, neither in the inter- nor in the intragroup comparison. Conclusion Similarly to a conventional strength training improvements in exercise capacity could be achieved with a SMT during PR in COPD patients. Further studies are necessary to define the role of the SMT in regards to postural control. © Georg Thieme Verlag KG Stuttgart · New York.

The aim of the study was to evaluate the cognitive functioning of children and youth with type 1 diabetes (T1DM). The study included 68 children with type 1 diabetes, aged 6-17 years, divided into 3 groups according to the level of glycated hemoglobin (HbA1c): group 1: HbA1c ≤ 6.0-7.5%; group 2: HbA1c 7.6-8.5%; group 3: HbA1c over 8.6%. Wechsler's intelligence scale (WISC-R), the Trail of 10 words and Brickenkamp's and Zillmer's d2 Test of Attention were used to assess cognitive functioning. The research demonstrated a significant influence of low, medium or high glycaemic control on lowering the general level of functioning in verbal intelligence, and in WISC-R subtests: information, vocabulary, comprehension, number sequencing and block design. Children with type 1 diabetes mellitus can experience difficulties in cognitive functioning, as a consequence of high HbA1c. Additional research, involving a larger group of patients and a wider age range when the disease was diagnosed, will enable further findings on the occurrence of cognitive impairment in T1DM.

To observe the clinical efficacy differences between different needling methods for dry eye syndrome. Sixty patients of dry eye syndrome were randomly divided into an observation group and a control group, 30 cases (60 eyes) in each group. Shangjingming (Extra), Xiajingming (Extra), Tongziliao (GB 1), Cuanzhu (BL 2), Fengchi (GB 20), Hegu (LI 4), Sanyinjiao (SP 6), Taixi (KI 3) and Taichong (LR 3) were selected in the two groups. The control group was treated with conventional acupuncture, while the observation group was treated with guiding- qi acupuncture. Electroacupuncture (EA) was used at bilateral Tongziliao (GB1) and Cuanzhu (BL 2), 30 min per treatment. The treatment was given three times per week. Totally 1-month treatment (12 treatments) was given. The eye symptom score, breakup time of tear film (BUT), Schirmer Ⅰ test (SⅠT) and visual analogue scale (VAS) score were compared before and after treatment in the two groups. The clinical efficacy was compared between the two groups. Compared before treatment, the eye symptom score, BUT, SⅠT and VAS score were improved after treatment in the two groups (all P <0.001); the improvements of eye symptom score and SⅠT in the observation group were superior to those in the control group (both P <0.05). The differences of BUT and VSA score between the two groups were not significant (both P >0.05). The total effective rate was 86.7% (52/60) in the observation group, which was superior to 73.3% (44/60) in the control group ( P <0.05). . The conventional EA and guiding- qi acupuncture combined with EA are both effective for dry eye syndrome, and the efficacy of guiding- qi acupuncture combined with EA is superior to that of conventional EA.

This Research Communication describes the effects of a synthetic analogue of the Bovine Appeasing Pheromone (BAP) on milk parameters in Valdostana dairy cows during the first turning out from tie-stalls to confined lowland pastures around the farms. Thirty healthy lactating Valdostana cows were enroled in the study and randomly divided into 2 groups: experimental group (EG, n = 15) and control group (CG, n = 15). The two groups were separately housed in the same farm and managed outside in two different pens. Treatment (BAP and solution) and control (solution only) were poured on the nuchal skin area between the horns when the animals were inside the farm at the feeding rack every 7 d for 28 d (T0-T4). Milk samples were evaluated at the same time points (T0-T4). Daily milk production (kg/day) was higher in the EG than in the CG, particularly during the first day after the turning out to pasture (T1). Somatic Cell Count (103 cells/ml) was higher in the placebo group than in the EG, especially at T1. Proteins, fat, fat-free dry matter and casein (g/100 g) were not affected by the treatment. In T1 urea (mg/dl) content was higher in CG vs. EG, suggesting a more correct metabolic balance in the group treated with BAP. The use of BAP appears to modulate adaptation in ways that may improve dairy cow performance in the context of changes in management routines.

To explore the effects of parecoxib sodium analgesia on serum concentrations of neuron-specific enolase (NSE) and S-100β and postoperative cognitive function of elderly patients undergoing acute replacement of femoral head. After the approval of institutional review board and the provision of informed consent, 80 patients over 70 years old, undergoing acute replacement of femoral head under combined spinal and epidural anesthesia and midazolam sedation at Qingdao Municipal Hospital and Qingdao Hiser Medical Center from January 2011 to May 2012, were randomly assigned into control group (group C, n = 40) and parecoxib group (group P, n = 40). In group P, parecoxib sodium 20/40 mg (based on weight 50 kg) was administered via an intravenous injection after admission with 12 hours intervals for six times. In group C, morphine 2/4 mg was given initially. Additional morphine 2 mg was given to maintain the pain visual analog scale (VAS) of 3 points or less in both groups. Primary observation indices: (1) postoperative time and additional amount of morphine; (2) rate of postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) at 3 days, 1 week, 3 months and 6 months postoperation (T1-T4); (3) se rum levels of NSE and S-100β were measured at the timepoints of before analgesia (t0), before anesthesia (t1), end of surgery (t2) and 6 hours, 24 hours, 48 hours postoperation (t3-t5); (4) other serious complications. Compared with group C, the additional amount of morphine, postoperative time, rate of POD and POCD at T1-T4, the level of NSE at t2-t5 and S-100β at t1-t5 were lower in group P (P < 0.05). No other serious complications were observed. Parecoxib sodium analgesia reduces the rate of POD and POCD in elderly patients with neuroprotective effects.

2014-11-25

Compared to American Whites, African Americans have a higher prevalence of type 2 diabetes mellitus (T2DM), experiencing poorer metabolic control and greater risks for complications and death. Patient-level factors, such as diabetes knowledge, self-management skills, empowerment, and perceived control, account for >90% of the variance observed in outcomes between these racial groups. There is strong evidence that self-management interventions that include telephone-delivered diabetes education and skills training are effective at improving metabolic control in diabetes. Web-based home telemonitoring systems in conjunction with active care management are also effective ways to lower glycosylated hemoglobin A1c values when compared to standard care, and provide feedback to patients; however, there are no studies in African Americans with poorly controlled T2DM that examine the use of technology-based feedback to tailor or augment diabetes education and skills training. This study provides a unique opportunity to address this gap in the literature. We describe an ongoing 4-year randomized clinical trial, which will test the efficacy of a technology-intensified diabetes education and skills training (TIDES) intervention in African Americans with poorly controlled T2DM. Two hundred male and female AfricanAmerican participants, 21 years of age or older and with a glycosylated hemoglobin A1c level ≥ 8%, will be randomized into one of two groups for 12 weeks of telephone interventions: (1) TIDES intervention group or (2) a usual-care group. Participants will be followed for 12 months to ascertain the effect of the interventions on glycemic control. Our primary hypothesis is that, among African Americans with poorly controlled T2DM, patients randomized to the TIDES intervention will have significantly greater reduction in glycosylated hemoglobin A1c at 12 months of follow-up compared to the usual-care group. Results from this study will add to the current literature examining how best to deliver diabetes education and skills training and provide important insight into effective strategies to improve metabolic control and hence reduce diabetes complications and mortality rates in African Americans with poorly controlled T2DM. This study was registered with the National Institutes of Health Clinical Trials Registry on 13 March 2014 (ClinicalTrials.gov identifier# NCT02088658).

Demyelination was induced by two weeks cuprizone treatment. Rats of +ve control and triiodothyronine (T3) then received three subcutaneous injections of either saline or T3 day after day and sacrificed at the end of the third and fifth weeks. Animals in -ve control group received only standard rodent chow. After one week of cuprizone withdrawal the corpus callosum in +ve control and T3 treated rats was still demyelinated as revealed by MBP immunohistochemistry. The assay of PLP gene showed significant increase of T3 treated group compared to both the -ve control and +ve control groups. After three weeks, significant improvement in myelination was detected in T3-treated group compared to +ve control as detected by both MBP immunohistochemistry and electron microscopy. After one week of cuprizone withdrawal, PDGFRα positive cells and gene expression showed significant increase in +ve control and T3-treated groups as compared to -ve control with insignificant difference in between the former two groups. After three weeks of cuprizone withdrawal, PDGFRα positive cells in T3-treated and +ve control groups decreased to the control levels. These results suggest that T3 was effective in improving remyelination when administered during acute phase and might direct progenitor lineage toward oligodendrocytes. Copyright © 2016 Elsevier Ltd.

Adult-onset hypothyroidism induces a variety of impairments on hippocampus- dependent neurocognitive functioningin which many synaptic proteins in hippocampus neurons are involved. Here, we observed the effect of adult-onset hypothyroidism on the expression of syntaxin-1 and munc-18 in the dorsal hippocampus and whether the altered proteins could be restored by levothyroxine (T4) treatment. All rats were separated into 4 groups randomly: hypothyroid group, 5 µg T4 /100 g body weight (BW) treated group, 20 µg T4/100 g BW treated group and control group. The radioimmunoassay kits were applied to assay the levels of serum T3 and T4, and the levels of syntaxin-1 and munc-18 in hippocampus were assessed by immunohistochemistry and Western blot. Both analysis corroborated that syntaxin-1 in the hypothyroid group was significantly higher. Munc-18 was lower in four layers of CA3 and dentate gyrus by immunohistochemistry. After two weeks of treatment with 5 µg T4/100 g BW for hypothyroidism, syntaxin-1 levels were completely restored, whereas the recovery of munc-18 only located in two of the four impaired layers. Twenty µg T4/100 g BW treatment normalized munc-18 levels. These data suggested that adult-onset hypothyroidism induced increment of syntaxin-1 and decrement of munc-18 in the dorsal hippocampus, which could be restored by T4 treatment. Larger dosage of T4 caused more effective restorations. PMID:22688303

Cognitive behavioral therapy has been shown to be effective for treating chronic pain, and a growing literature shows the potential analgesic effects of minimally invasive brain stimulation. However, few studies have systematically investigated the potential benefits associated with combining approaches. The goal of this pilot laboratory study was to investigate the combination of a brief cognitive restructuring intervention and transcranial direct current stimulation (tDCS) over the left dorsolateral prefrontal cortex in affecting pain tolerance. Randomized, double-blind, placebo-controlled laboratory pilot. Medical University of South Carolina. A total of 79 healthy adult volunteers. Subjects were randomized into one of six groups: 1) anodal tDCS plus a brief cognitive intervention (BCI); 2) anodal tDCS plus pain education; 3) cathodal tDCS plus BCI; 4) cathodal tDCS plus pain education; 5) sham tDCS plus BCI; and 6) sham tDCS plus pain education. Participants underwent thermal pain tolerance testing pre- and postintervention using the Method of Limits. A significant main effect for time (pre-post intervention) was found, as well as for baseline thermal pain tolerance (covariate) in the model. A significant time × group interaction effect was found on thermal pain tolerance. Each of the five groups that received at least one active intervention outperformed the group receiving sham tDCS and pain education only (i.e., control group), with the exception of the anodal tDCS + education-only group. Cathodal tDCS combined with the BCI produced the largest analgesic effect. Combining cathodal tDCS with BCI yielded the largest analgesic effect of all the conditions tested. Future research might find stronger interactive effects of combined tDCS and a cognitive intervention with larger doses of each intervention. Because this controlled laboratory pilot employed an acute pain analogue and the cognitive intervention did not authentically represent cognitive behavioral therapy per se, the implications of the findings on chronic pain management remain unclear.

Research investigating maternal bonding and parenting stress in the course of postpartum depression is lacking. Aim of the study was to investigate the development and potential mediation of both constructs in the course of postpartum depression. n = 31 mothers with postpartum depression according to DSM-IV and n = 32 healthy controls completed the German version of the Postpartum Bonding Questionnaire and the Parenting Stress Index at two measuring times: acute depression (T1) and remission (T2). At T1, the clinical group reported lower bonding and higher parenting stress. Bonding was found to partially mediate the link between maternal diagnosis and parenting stress. Furthermore, the clinical group reported lower bonding and higher parenting stress averaged over both measurement times. However, at T2, the clinical group still differed from the controls even though they improved in bonding and reported less parenting stress. A significant increase of bonding was also observed in the control group. Maternal bonding seems to buffer the negative impact of postpartum depression on parenting stress. The results emphasize the need for interventions focusing on maternal bonding and mother-infant interaction in order to prevent impairment of the mother-child relationship.

To study the relationship between type 2 diabetes mellitus (T2DM) and oral lichen planus (OLP) by detecting the level of salivary tumor necrosis factor (TNF-α) and interlukin-6 (IL-6). Subjects were divided into 4 groups: T2DM/OLP group 29 patients, T2DM group 39 patients, OLP group 21 patients, and control group 43 individuals. The salivary interleukin-6 (IL-6) and tumor necrosis factor (TNF-α) were detected by enzyme-linked immuno sorbent assay (ELISA). (1) The level of salivary IL-6 in patients with T2DM/OLP [(12.30 ± 16.03) ng/L] was significantly higher than those in T2DM [(6.29 ± 5.91) ng/L] and OLP groups [(3.64 ± 4.47) ng/L], P<0.05. The level of salivary IL-6 was significantly lower in OLP group [(3.64 ± 4.47) ng/L] than in control group [(7.91 ± 4.05) ng/L], P<0.001. The level of salivary TNF-α in T2DM group [(8.80 ± 8.41) ng/L] was significantly lower than those in OLP [(14.02 ± 9.65) ng/L] and control groups [(15.02 ± 6.13) ng/L], P<0.05. (2) The level of salivary TNF-α is significantly negative correlated with pH value of saliva in T2DM/OLP group(r=-0.593, P<0.01);The level of salivary TNF-α and IL-6 are significantly positive correlated with waistline in control group(r=0.312,P=0.05).(3) The levels of salivary IL-6 and TNF-α were positively related to OLP clinical type, P<0.05. (4)When OLP played an overlying role on T2DM, the level of TNF-α was weakened and that of IL-6 was strengthened. When T2DM and OLP are in concurrence,there is a synergistic effect,and the secretion of IL-6 increases markedly; The level of salivary TNF-α is associated with local oral environment.

We hypothesize that the nebulization of gamma-tocopherol (g-T) in the airway of our ovine model of acute respiratory distress syndrome (ARDS) will effectively improve pulmonary function following burn and smoke inhalation after 96 hours. Adult ewes (n=14) were subjected to 40% total body surface area burn and were insufflated with 48 breaths of cotton smoke under deep anesthesia, in a double-blind comparative study. A customized aerosolization device continuously delivered g-T in ethanol with each breath from 3 to 48 hours after the injury (g-T group, n=6), while the control group (n=5) was nebulized with only ethanol. Animals were weaned from the ventilator when possible. All animals were sacrificed after 96 hours, with the exception of one untreated animal that was euthanized after 64 hours. Lung g-T concentration significantly increased after g-T nebulization compared to the control group (38.5±16.8 nmol/g vs. 0.39±0.46, p<0.01). The PaO2/FiO2 ratio was significantly higher after treatment with g-T compared to the control group (310±152 vs 150±27.0, p<0.05). The following clinical parameters were improved with g-T treatment: pulmonary shunt fraction, peak and pause pressures, lung bloodless wet-to-dry weight ratios (2.9±0.87 vs 4.6±1.4, p<0.05), and bronchiolar obstruction (2.0±1.1% vs 4.6±1.7%, p<0.05). Nebulization of g-T, carried by ethanol, improved pulmonary oxygenation and markedly reduced the time necessary for assisted ventilation in burn and smoke injured sheep. Delivery of g-T into the lungs may be a safe, novel, and efficient approach for management of ALI patients who have sustained oxidative damage to the airway. PMID:22266978

Forty, newly hatched, unsexed broiler chicks were fed diets containing 10 ppm cyclopiazonic acid (CPA) and 1 ppm T-2 toxin (T2) either individually or in combination for 28 days to study the immunopathological effects. Lymphoid organs revealed lymphocytolysis and lymphoid depletion in all toxin fed birds. Thymic and splenic CD+4 and CD+8 lymphocytes decreased significantly (p<0.01) in toxin fed birds when compared to the control. Thymic CD+8 lymphocytes of T2 and CPA-T2 showed significant (p<0.01) decrease from that of CPA and control groups. Splenic CD+4 and CD+8 lymphocytes showed significant (p<0.01) decrease in CPA and CPA-T2 fed groups when compared to the control. The T2 group did not differ significantly from that of control. The stimulation index (SI) of splenocytes to concavalin A revealed significant (p<0.01) decrease in all toxin fed birds. Significant (p<0.01) decrease were observed for the haemagglutination inhibition (HI) titres to Newcastle disease virus vaccine F strain (NDV) of birds fed CPA, T2 and in combination. Significant (p<0.01) interaction was found for lymphocyte subsets, SI and HI titres to NDV. The study indicated the immunosuppressive effect of these toxins either alone or in combination in broiler chicks.

Anodal Transcranial Direct Current Stimulation Shows Minimal, Measure-Specific Effects on Dynamic Postural Control in Young and Older Adults: A Double Blind, Sham-Controlled Study

We investigated whether stimulating the cerebellum and primary motor cortex (M1) using transcranial direct current stimulation (tDCS) could affect postural control in young and older adults. tDCS was employed using a double-blind, sham-controlled design, in which young (aged 18–35) and older adults (aged 65+) were assessed over three sessions, one for each stimulatory condition–M1, cerebellar and sham. The effect of tDCS on postural control was assessed using a sway-referencing paradigm, which induced platform rotations in proportion to the participant’s body sway, thus assessing sensory reweighting processes. Task difficulty was manipulated so that young adults experienced a support surface that was twice as compliant as that of older adults, in order to minimise baseline age differences in postural sway. Effects of tDCS on postural control were assessed during, immediately after and 30 minutes after tDCS. Additionally, the effect of tDCS on corticospinal excitability was measured by evaluating motor evoked potentials using transcranial magnetic stimulation immediately after and 30 minutes after tDCS. Minimal effects of tDCS on postural control were found in the eyes open condition only, and this was dependent on the measure assessed and age group. For young adults, stimulation had only offline effects, as cerebellar stimulation showed higher mean power frequency (MPF) of sway 30 minutes after stimulation. For older adults, both stimulation conditions delayed the increase in sway amplitude witnessed between blocks one and two until stimulation was no longer active. In conclusion, despite tDCS’ growing popularity, we would caution researchers to consider carefully the type of measures assessed and the groups targeted in tDCS studies of postural control.

This study protocol will evaluate the effectiveness and safety during labor and delivery of the Kinesio Taping bandage for pain sensation, satisfaction of patients, and obstetric and neonatal outcomes. A randomized controlled trial with 60 participants divided into two groups will be conducted. The intervention group will receive bandage application on the vertebral regions corresponding to uterine dermatomes - from T10 to L1 and from S2 to S4. The control group will receive bandage application away from uterine dermatomes, from T1 to T4. The primary endpoint is pain during labor. Secondary endpoints are perinatal outcomes and patient satisfaction with the bandage and with her labor. Pain levels will be evaluated on an hourly basis during labor, and intention-to-treat analysis will be performed. Risk ratios and 95% confidence intervals will be calculated. Findings on effectiveness of pain control with no adverse effects to both the mother and neonate are the first step in evaluating the systematic use of Kinesio Taping during labor. Since self-control may affect birthing experience satisfaction, discovering new alternatives for pain control may allow for a better experience. © 2017 John Wiley & Sons Australia, Ltd.

Modulation of the immune responses using active bio-ingredients as a possible prophylaxis measure has been novel prospect for aquaculture. The present study evaluated the effects of azadirachtin EC 25% on non-specific immune responses in goldfish Carassius auratus and resistance against pathogenic bacteria Aeromonas hydrophila. The experimental trial for effects of azadirachtin on immuno-haematoloical parameters in goldfish was conducted by feeding the various levels of azadirachtin as control T(0) (without azadirachtin), T(1) (0.1%), T(2) (0.2%), T(3) (0.4%), T(4) (0.8%) and T(5) (1.6%) for a period of 28 days. Fishes were challenged with A. hydrophila 28 days post feeding and relative percentage survival (%) was recorded over 14 days post infection. Immuno-haematoloical (total erythrocyte count, total leukocyte count, haemoglobin, packed cell volume, NBT activity, phagocytic activity, serum lysozyme activity, myeloperoxidase activity, total immunoglobulin) and serum biochemical parameters (serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT) and blood glucose) of fishes were examined at 14 and 28 days of feedings. Fish fed with azadirachtin, showed significantly (p < 0.05) enhanced TEC, TLC, Total Ig, total protein, NBT activity, serum lysozyme activity and myeloperoxidase level in different treatment groups in comparison with control group. Similarly, SGOT, SGPT and blood glucose level were found to be significantly (p < 0.05) high but PCV and Hb did not differ significantly (p > 0.05) in the treatment groups compared to control groups. Azadirachtin at the concentration of 4 g kg(-1) showed significantly (p < 0.05) higher relative percentage survival (42.60%) when compared with the control against A. hydrophila infection. This study indicated that azadirachtin EC 25% (4 g kg(-1)) showed higher NBT activity, serum lysozyme, protein profiles, leukocyte counts and resistance against A. hydrophila infection and thus, can be used as a potential immunostimulant in aquaculture.

The aim of the present study was to investigate the effectiveness of Samarium(153)-particulate hydroxyapatite radiation synovectomy in rheumatoid arthritis patients with chronic knee synovitis. Fifty-eight rheumatoid arthritis patients (60 knees) with chronic knee synovitis participated in a controlled double-blinded trial. Patients were randomized to receive either an intra-articular injection with 40 mg triamcinolone hexacetonide alone (TH group) or 40 mg triamcinolone hexacetonide combined with 15 mCi Samarium(153)-particulate hydroxyapatite (Sm/TH group). Blinded examination at baseline (T0) and at 1 (T1), 4 (T4), 12 (T12), 32 (T32), and 48 (T48) weeks post-intervention were performed on all patients and included a visual analog scale for joint pain and swelling as well as data on morning stiffness, flexion, extension, knee circumference, Likert scale of improvement, percentage of improvement, SF-36 generic quality of life questionnaire, Stanford Health Assessment Questionnaire (HAQ), Lequesne index, use of non-steroidal anti-inflammatory drugs or oral corticosteroids, events and adverse effects, calls to the physician, and hospital visits. The sample was homogeneous at baseline, and there were no withdrawals. Improvement was observed in both groups in relation to T0, but no statistically significant differences between groups were observed regarding all variables at the time points studied. The Sm/TH group exhibited more adverse effects at T1 (p<0.05), but these were mild and transitory. No severe adverse effects were reported during follow-up. Intra-articular injection of Samarium(153)-particulate hydroxyapatite (15 mCi) with 40 mg of triamcinolone hexacetonide is not superior to triamcinolone hexacetonide alone for the treatment of knee synovitis in patients with rheumatoid arthritis at 1 y of follow-up.

Several studies have reported increased fracture risk in Type 1 diabetes mellitus (T1DM). Quantitative Ultrasound (QUS) provides information on the structure and elastic properties of bone, which are important determinants of fracture risk, along with bone mineral density. To study phalangeal sites by QUS, examine bone turnover markers and analyze association between these factors with metabolic control in a population of pre-menopausal women with T1DM. Thirty-five T1DM pre-menopausal women (mean age 34.5 ± 6.8 yr) attending the Diabetic Outpatients Clinic in the Department of Internal Medicine, University of Messina, were consecutively enrolled and divided into two groups, taking into account the mean value of glycated hemoglobin in the last three years. Twenty healthy age-matched women served as controls. Phalangeal ultrasound measurements [Amplitude Dependent Speed of Sound (AD-SoS), Ultrasound Bone Profile Index (UBPI), TScore, Z-Score] were performed using a DBM Sonic Bone Profiler. Osteocalcin and deoxypyridinoline served as markers of bone formation and bone resorption, respectively. T1DM women with poor metabolic control showed lower phalangeal QUS values compared to healthy controls (p<0.01) and T1DM women with good metabolic control (p<0.05). No significant differences in QUS measurements were detected between T1DM women with good metabolic control and healthy controls. Lower bone formation and increased bone resorption, although not statistically significant, were observed in patients with poor metabolic control in comparison to patients with good metabolic control. Poor metabolic control may worsen the quality of bone in T1DM. Phalangeal QUS could be considered as a tool to screen T1DM women for osteoporosis in pre-menopausal age.

To assess changes in oral microflora in dental plaque from cancer patients within 7 days of the first course of chemotherapy, and the relationship of the changes with mucositis. Thirty cancer patients, divided into a test group undergoing chemotherapy and a control group no undergoing chemotherapy, were enrolled in this pilot study. Oral microflora were cultured from three samples of dental plaque at t0 (before chemotherapy), t1 (1 day after chemotherapy) and t2 (7 days after chemotherapy). Single and crossed descriptive analyses were used to establish prevalence, and the χ² test was used to establish the statistical significance of the differences observed in distributions (significance level: P<0.05). In most patients (57%), oral microflora consisted mainly of Gram-positive cocci, while the remaining 43% of the bacterial flora also had periodontal-pathogenic species. No Porphyromonas gingivalis appeared in the test group. Actinobacillus was the least frequently found bacterium among periodontal pathogens in the test group, while Fusobacterium nucleatum was the most frequently found. No significant differences were found in quantitative bacterial changes between t0, t1 and t2 in either the test or control groups, or between the two groups. According to World Health Organization scores, oral mucositis developed in 10 patients (66.6%) in the test group. The results of this pilot study indicate that there were no changes in microflora in dental plaque in cancer patients within 7 days of the first course of chemotherapy. No correlations between oral mucositis and specific microorganisms were assessed.

Levothyroxine (L-T4) treatment of euthyroid children with Hashimoto thyroiditis (HT) is a controversial issue. We conducted a prospective, randomized, controlled clinical trial. Out of 79 identified euthyroid patients, 59 started the study; 25 patients (21 female, 4 male; age: 11.8 ± 2.3 years) received L-T4 at a mean dose of 1.6 µg/kg (SD, 0.8) daily, and 34 (27 female, 7 male; age: 12.6 ± 1.2 years) were not treated. Patients developing subclinical hypothyroidism during follow-up (n = 13) were treated with L-T4 and removed from the observation group. As the main outcome measures, thyroid gland volume (determined by ultrasound) as well as serum levels of TSH, free T4, and antibodies against thyroid peroxidase and thyroglobulin were assessed every 6 months for 36 months. At the start, the mean thyroid volume (standard deviation score, SDS) was 2.5 in the treatment group and 1.6 in the observation group. There was a constant decline in mean thyroid volume (SDS) from 2.13 (month 12) to 1.12 (month 30) in the treated group, with a delta thyroid volume of -1.01 SDS. In the observation group, the mean delta thyroid volume increased to +0.27 SDS. The change of the delta thyroid volume was statistically significantly different between both groups during the 12- and 30-month time points (p < 0.05). L-T4 had no effect on thyroid function and serum thyroid antibodies. L-T4 treatment can decrease the thyroid volume in euthyroid children with HT, but the effect is limited to a definite time period. © 2015 S. Karger AG, Basel.

To determine the range of asymptomatic abnormal findings in adolescent soccer players at 3.0T MRI of the knee. In all, 87 knees of asymptomatic 14-17-year-old male adolescents were evaluated at 3T, using a standardized examination protocol comprising four sequences: two fat-suppressed T 2 -weighted fast spin-echo sequences (T 2 FSE), in the sagittal (repetition time / echo time [TR/TE], 5.300/71, echo train length [ETL] 17) and coronal planes (TR/TE, 4234/70, ETL 17), one fat-suppressed proton density (PD) sequence in the axial plane (TR/TE, 2.467/40, ETL 9), and one T 1 -weighted spin-echo (T 1 SE) sequence in the sagittal plane (TR/TE, 684/12.5). Soccer players (46 knees) were paired with controls (41 knees) by age and weight. Bone marrow, articular cartilage, meniscus, tendons, ligaments, fat pad abnormalities, and joint fluid were assessed. One or more abnormalities were detected in 31 knees (67.4%) in the soccer player group, compared to 20 knees (48.8%) in the control group. The prevalence of bone marrow edema was higher in the soccer group (19 knees, 41.3%) than in the control group (3 knees, 7.3%), P = 0.001. Other abnormalities found in this sample (joint effusion, cartilage lesions, tendinopathy, ganglion cysts, and infrapatellar fat pat edema) were not significantly different between the two study groups. Asymptomatic adolescents had a high prevalence of abnormal findings on knee imaging, especially bone marrow edema. This prevalence was higher among soccer players. 4 J. Magn. Reson.

Background There is an emerging interest in using magnetic resonance imaging (MRI) T2* measurement for the evaluation of degenerative cartilage in osteoarthritis (OA). However, relatively few studies have addressed OA-related changes in adjacent knee structures. This study used MRI T2* measurement to investigate sequential changes in knee cartilage, meniscus, and subchondral bone marrow in a rat OA model induced by anterior cruciate ligament transection (ACLX). Materials and Methods Eighteen male Sprague Dawley rats were randomly separated into three groups (n = 6 each group). Group 1 was the normal control group. Groups 2 and 3 received ACLX and sham-ACLX, respectively, of the right knee. T2* values were measured in the knee cartilage, the meniscus, and femoral subchondral bone marrow of all rats at 0, 4, 13, and 18 weeks after surgery. Results Cartilage T2* values were significantly higher at 4, 13, and 18 weeks postoperatively in rats of the ACLX group than in rats of the control and sham groups (p<0.001). In the ACLX group (compared to the sham and control groups), T2* values increased significantly first in the posterior horn of the medial meniscus at 4 weeks (p = 0.001), then in the anterior horn of the medial meniscus at 13 weeks (p<0.001), and began to increase significantly in the femoral subchondral bone marrow at 13 weeks (p = 0.043). Conclusion Quantitative MR T2* measurements of OA-related tissues are feasible. Sequential change in T2* over time in cartilage, meniscus, and subchondral bone marrow were documented. This information could be potentially useful for in vivo monitoring of disease progression. PMID:24204653

Women of reproductive age are a group of particular concern as diabetes may affect their pregnancy outcome as well as long-term morbidity and mortality. This study aimed to compare the clinical profiles and glycemic control of reproductive and non-reproductive age women with type 2 diabetes (T2D) in primary care settings, and to determine the associated factors of poor glycemic control in the reproductive age group women. This was a cross-sectional study using cases reported by public primary care clinics to the Adult Diabetes Control and Management registry from 1st January to 31st December 2009. All Malaysian women aged 18 years old and above and diagnosed with T2D for at least 1 year were included in the analysis. The target for glycemic control (HbA1c < 6.5%) is in accordance to the recommended national guidelines. Both univariate and multivariate approaches of logistic regression were applied to determine whether reproductive age women have an association with poor glycemic control. Data from a total of 30,427 women were analyzed and 21.8% (6,622) were of reproductive age. There were 12.5% of reproductive age women and 18.0% of non-reproductive age women that achieved glycemic control. Reproductive age group women were associated with poorer glycemic control (OR = 1.5, 95% CI = 1.2-1.8). The risk factors associated with poor glycemic control in the reproductive age women were being of Malay and Indian race, longer duration of diabetes, patients on anti-diabetic agents, and those who had not achieved the target total cholesterol and triglycerides. Women with T2D have poor glycemic control, but being of reproductive age was associated with even poorer control. Health care providers need to pay more attention to this group of patients especially for those with risk factors. More aggressive therapeutic strategies to improve their cardiometabolic control and pregnancy outcome are warranted.

Craving, as a central feature of addiction and a precursor of relapse, is targeted recently in addiction intervention. While Internet gaming disorder (IGD), conceptualized as a behavioral addiction, is lack of effective treatment practice and exploration of its mechanism. This research aims to test the effectiveness and detect the active ingredients of craving behavior intervention (CBI) in mitigation of IGD among young adults. A total of 63 male college students with IGD were assigned into the intervention group (six-session CBI intervention) or the waiting-list control group. Structured questionnaires were administered at pre-intervention (T1), post-intervention (T2), 3-month follow-up (T3), and 6-month follow-up (T4). Compared to the control group, a significant decrease in the severity of IGD in intervention group was found at post-intervention and lasting to 6 months after intervention. The value changes of craving could partially mediate the relationship between intervention and changes of IGD among all effects tests (immediate, T2-T1; short-term, T3-T1; and long-term effects, T4-T1). Further, explorations of the active ingredients of intervention found depression relief and shift of psychological needs from Internet to real life significantly predict craving amelioration at both post-intervention and 6-month follow-up. Although preliminary, the current study provides evidence for the value of craving-aimed intervention practice in IGD treatment and identifies two potential active ingredients for mitigation of craving, and the long-term therapeutic benefits are further conferred.

To evaluate the effectiveness of aviation-style teamwork training in improving operating theatre team performance and clinical outcomes. 3 operating theatres in a UK district general hospital, 1 acting as a control group and the other 2 as the intervention group. 72 operations (37 intervention, 35 control) were observed in full by 2 trained observers during two 3-month observation periods, before and after the intervention period. A 1-day teamwork training course for all staff, followed by 6 weeks of weekly in-service coaching to embed learning. We measured team non-technical skills using Oxford NOTECHS II, (evaluating the whole team and the surgical, anaesthetic and nursing subteams, and evaluated technical performance using the Glitch count. We evaluated compliance with the WHO checklist by recording whether time-out (T/O) and sign-out (S/O) were attempted, and whether T/O was fully complied with. We recorded complications, re-admissions and duration of hospital stay using hospital administrative data. We compared the before-after change in the intervention and control groups using 2-way analysis of variance (ANOVA) and regression modelling. Mean NOTECHS II score increased significantly from 71.6 to 75.4 in the active group but remained static in the control group (p=0.047). Among staff subgroups, the nursing score increased significantly (p=0.006), but the anaesthetic and surgical scores did not. The attempt rate for WHO T/O procedures increased significantly in both active and control groups, but full compliance with T/O improved only in the active group (p=0.003). Mean glitch rate was unchanged in the control group but increased significantly (7.2-10.2/h, p=0.002) in the active group. Teamwork training was associated with improved non-technical skills in theatre teams but also with a rise in operative glitches. Published by the BMJ Publishing Group Limited.

The aim of this study was to compare the effectiveness of antioxidants including Achillea millefolium extract (AmE) (n0t1.5: 1.5, n0t3: 3 and n0t4.5: 4.5 mg/L) and AmE loaded in nano phytosome (n1t1.5: 1.5, n1t3: 3 and n1t4.5: 4.5 mg/L) in the freezing of Ross 308 rooster semen. Sperm motility (CASA), membrane integrity (HOS test), viability, total abnormality and enzymatic parameters (SOD, CAT and GPx) were assessed after thawing. AmE-loaded nano phytosome at a concentration of 3 mg/l resulted in significantly (P < 0.05) higher total motility (MOT) (73.78 ± 2.92) and at concentrations of 1.5 mg/L and 3 mg/L in progressive motility (PROG) (14.12 ± 0.38, 16.78 ± 0.38) in comparison with the control group (MOT: 58.48 ± 2.92; PROG: 9.08 ± 0.38). Sperm viability (Vi) was higher (P < 0.05) in n1t3 (74.62 ± 1.55) and membrane integrity (Mi) in n0t3 and n1t3 groups (65.91 ± 1.91, 63.73 ± 1.91, respectively) compared to the control groups (Vi: 66.85 ± 1.55; Mi: 53.18 ± 1.91). Moreover, the lowest percentage of MDA was measured in n1t3 group (1.31 ± 0.31). There was no significant difference for SOD and CAT values with the use of various extenders. In conclusion, we suggest that AmE loaded in nano phytosome at 3 mg/l dose can be added to basic extender for improving rooster sperm motility, viability and oxidative stress values during the freezing procedure.

Type 2 diabetes mellitus (T2DM) is one of the most frequent metabolic disorders in industrialized countries. Among other complications, T2DM patients have an increased fracture risk and delayed fracture healing. We have demonstrated that supraphysiological glucose and insulin levels inhibit primary human osteoblasts' maturation. We aimed at developing a more physiologically relevant in vitro model to analyze T2DM-mediated osteoblast changes. Therefore, SCP-1-immortalized pre-osteoblasts were differentiated with T2DM or control (non-obese and obese) sera. Between both control groups, no significant changes were observed. Proliferation was significantly increased (1.69-fold), while AP activity and matrix mineralization was significantly reduced in the T2DM group.more » Expression levels of osteogenic marker genes and transcription factors were altered, e.g. down-regulation of RUNX2 and SP-7 or up-regulation of STAT1, in the T2DM group. Active TGF-β levels were significantly increased (1.46-fold) in T2DM patients' sera. SCP-1 cells treated with these sera showed significantly increased TGF-β signaling (2.47-fold). Signaling inhibition effectively restored osteoblast maturation in the T2DM group. Summarizing our data, SCP-1 cells differentiated in the presence of T2DM patients' serum exhibit reduced osteoblast function. Thus, this model has a high physiological impact, as it can identify circulating factors in T2DM patients' blood that may affect bone function, e.g. TGF-β. - Highlights: • We present here a physiologically relevant in vitro model for diabetic osteopathy. • Blood of T2DM patients contains factors that affect osteoblasts' function. • The model developed here can be used to identify these factors, e.g. TGF-β. • Blocking TGF-β signaling partly rescues the osteoblasts' function in the T2DM group. • The model is useful to demonstrate the role of single factors in diabetic osteopathy.« less

The combination of an increasing prevalence of diabetes mellitus and more people having access to smartphones creates opportunities for patient care. This study aims to investigate whether the use of the Diabetes Under Control (DBEES) mobile phone application, a digital diabetes diary, results in a change in quality of life for patients with type 1 diabetes mellitus (T1DM) compared with the standard paper diary. In this randomized controlled open-label trial, 63 patients with T1DM having access to a smartphone were assigned to the intervention group using the DBEES application (n = 31) or the control group using the standard paper diary (n = 32). Primary outcome was the change in quality of life, as measured by the RAND-36 questionnaire, between both groups. Secondary outcomes included diabetes-related distress (PAID), HbA1c, frequency of self-monitoring blood glucose, and the usability of the diabetes application (SUS). Patients had a median age (IQR) of 33 (21) years, diabetes duration of 17 (16) years, and an HbA1c of 62 ± 16 mmol/mol. No significant differences in the QOL, using the RAND-36, within and between both groups were observed after 3 months. Glycemic control, diabetes-related emotional distress, and frequency of self-monitoring of blood glucose remained within and between groups. Users reviewed the usability of DBEES with a 72 ± 20, on a range of 0-100. The use of the DBEES application in the management of patients with T1DM for 3 months yields no alterations in quality of life compared to the standard paper diary. © 2015 Diabetes Technology Society.

The aim of this study was to investigate the effect of heat stress (HS) on digestibility of protein and fat and the expression of nutrient transporters in broilers. Forty-eight male Cobb500 chicks were used in this study. At day 14, birds were randomly divided into two groups and kept under either constant normal temperature (25 °C) or high temperature (35 °C) in individual cages. Five birds per treatment at 1 and 12 days post-treatment were euthanized, and Pectoralis major (P. major) and ileum were sampled for gene expression analysis. At day 33, ileal contents were collected and used for digestibility analysis. The total consumption and retention of protein and fat were significantly lower in the HS group compared to the control group. Meanwhile, the retention of crude protein per BWG was significantly higher in the HS group compared to the control group. In P. major and ileum tissues at day 1, transporters FATP1 and SGLT1 were down-regulated in the HS group. Meanwhile, FABP1 and PepT1 were down-regulated only in the ileum of the HS group. The converse was shown in P. major. The nutrient transporter FABP1 at day 12 post-HS was down-regulated in the P. major and ileum, but GLUT1 and PepT2 were down-regulated only in the ileum, and PepT1 was down-regulated only in the P. major compared with the control group. These changes in nutrient transporters suggest that high ambient temperature might change the ileum and P. major lipids, glucose, and oligopeptide transporters.

There is a dearth of studies regarding the influence of cigarette smoking on periodontal inflammatory conditions among patients with type 2 diabetes mellitus (T2DM). The aim of the present study is to assess periodontal inflammatory conditions among smokers and never-smokers with and without T2DM. One hundred individuals (50 patients with T2DM [25 smokers and 25 never-smokers] and 50 controls [25 smokers and 25 never-smokers]) were included. Information regarding age, sex, duration and daily frequency of smoking, duration and treatment of diabetes, and oral hygiene was recorded using a questionnaire. Periodontal parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD], clinical attachment loss [AL], and marginal bone loss [MBL]) were measured. Hemoglobin A1c (HbA1c) levels were also recorded. Mean age, monthly income status, and education levels were comparable among smokers and never-smokers with and without T2DM. Mean HbA1c levels were significantly higher among patients with T2DM (8.2% ± 0.1%) compared with controls (4.4% ± 0.3%) (P <0.05). Smokers in the control group were smoking significantly greater numbers of cigarettes (15.5 ± 2.5 cigarettes daily) compared with smokers with T2DM (6.2 ± 2.1 cigarettes daily) (P <0.05). Periodontal parameters were comparable among smokers and never-smokers with T2DM. Among controls, periodontal parameters (PI [P <0.05], AL [P <0.05], PD ≥4 mm [P <0.05], and MBL [P <0.05]) were significantly higher in smokers than never-smokers. Never-smokers with T2DM had worse periodontal status than smokers and never-smokers in the control group (P <0.05). Periodontal inflammatory conditions are comparable among smokers and never-smokers with T2DM. Among controls, periodontal inflammation is worse among smokers than never-smokers.

To explore the association of sedentary life style with risk of metabolic syndrome (MS) and diabetes mellitus type 2(T2DM). A total of 6 016 local residents aged 18 years or older in Fujian province were recruited by multi-stage stratified cluster sampling method in 2010-2011. Data, including demographic information, physical activity and sedentary time were collected. Indices related to height, weight, waist circumference, blood pressure and blood lipid were determined while MS and T2DM were diagnosed by IDF (2005) and WHO (1999) criteria. Logistic regression was used to estimate the correlations between sedentary behavior and MS or T2DM. The prevalence rates of MS and T2DM were 19.0% and 8.0% respectively, in local residents aged 18 years or older, in Fujian province. The overall rate of sedentary behavior was 18.1%, with the mean sedentary time as 4.3 hours. Both data showed significantly differences (P < 0.001) among control group,MS without T2DM group,MS with T2DM group and T2DM without MS group. Compared with the group of sedentary time <2.0 h/d, 1) the group with 2.0-3.5 h/d was significantly correlated with MT group (OR = 1.44, 95% CI:1.03-2.03, P < 0.05), 2) groups of 3.5-6.0 h/d and ≥6.0 h/d were significantly correlated with M, T, MT group, respectively (OR:1.49-1.76 and 1.28-1.58 respectively, 95% CI:1.19-2.45 and 1.02-2.23 respectively, P < 0.05), and 3) sedentary behavior was independently associated with an increased risk of MT group (OR = 1.82, 95% CI: 1.33-2.48, P < 0.01) and M group (OR = 1.43, 95%CI:1.14-1.78, P < 0.01), after the adjustment for factors as age, sex, cigarette smoking, alcohol drinking,BMI, education, occupation, sedentary behavior/sedentary time. MS and T2DM were associated with sedentary lifestyle, but these findings should be confirmed through further longitudinal studies.

The COL5A1 and COL12A1 variants are independently associated with modulating the risk of anterior cruciate ligament (ACL) rupture in females. The objective of this study was to further investigate if COL3A1 and COL6A1 variants independently, as well as, collagen gene-gene interactions, modulate ACL rupture risk. Three hundred and thirty-three South African (SA, n = 242) and Polish (PL, n = 91) participants with diagnosed ACL ruptures and 378 controls (235 SA and 143 PL) were recruited. Participants were genotyped for COL3A1 rs1800255 G/A, COL5A1 rs12722 (T/C), COL6A1 rs35796750 (T/C) and COL12A1 rs970547 (A/G). No significant associations were identified between COL6A1 rs35796750 and COL3A1 rs1800255 genotypes and risk of ACL rupture in the SA cohort. The COL3A1 AA genotype was, however, significantly (p = 0.036) over-represented in the PL ACL group (9.9%, n = 9) when compared to the PL control (CON) group (2.8%, n = 4). Although there were genotype distribution differences between the SA and PL cohorts, the T+A-inferred pseudo-haplotype constructed from COL5A1 and COL12A1 was significantly over-represented in the female ACL group when compared to the female CON group within the SA (T+A ACL 50.5%, T+A CON 38.1%, p = 0.022), PL (T+A ACL 56.3%, T+A CON 36.3%, p = 0.029) and combined (T+A ACL 51.8%, T+A CON 37.5%, p = 0.004) cohorts. In conclusion, the novel main finding of this study was a significant interaction between the COL5A1 rs12722 T/C and COL12A1 rs970547 A/G variants and risk of ACL injury. These results highlight the importance of investigating gene-gene interactions in the aetiology of ACL ruptures in multiple independent cohorts.

To evaluate the changes of CD(4)(+)IL-17(+) T (Th17) and CD(4)(+)Foxp3(+) regulatory T (Treg) cells in peripheral blood and bronchoalveolar lavage fluid (BALF), and therefore to explore the role of Th17 and Treg in cigarette smoke-induced airway inflammation/COPD in rats. Forty male Wistar rats were randomly divided into 4 groups: a 12 wk smoke-exposure group, a 24 wk smoke-exposure group, a 12 wk control group and a 24 wk control group (n = 10 each). Cells in BALF were collected and analyzed by absolute and differential cell counts. IL-17 and IL-6 levels in serum and BALF were tested by enzyme linked immunosorbent assay (ELISA). The proportion of CD(4)(+)IL-17(+) T and CD(4)(+)Foxp3(+) Treg in peripheral blood and BALF were determined by flow cytometry. The mRNA expressions of IL-17 and Foxp3 were measured by real-time PCR. Comparisons of the data between different groups were performed using one-way ANOVA, and SNK and Games-Howell test were used for comparison between 2 groups. Levels of IL-17 were remarkable increased in the 12 wk smoke-exposure group and the 24 wk smoke-exposure group in serum [(52.6 ± 1.8) ng/L, (75.4 ± 6.0) ng/L] and BALF [(78.1 ± 5.8) ng/L, (95.0 ± 6.8) ng/L] compared with the 12 wk control group [(40.0 ± 3.2)ng/L, (54.5 ± 4.6) ng/L] and the 24 wk control group [(36.7 ± 3.2) ng/L, (53.9 ± 3.7) ng/L], all P < 0.05. IL-6 in serum was significantly increased in the 24 wk smoke-exposure group [(31.4 ± 2.1) ng/L] compared with the 24 wk control group [(11.5 ± 0.5) ng/L], and it was increased in the 12 wk and the 24 wk smoke-exposure group [(33.3 ± 2.3) ng/L, (44.6 ± 3.0) ng/L] compared with the 12 wk and the 24 wk control group [(15.6 ± 1.8) ng/L, (18.0 ± 1.9) ng/L] in BALF. Ratio of Th17 was higher in the 12 wk and the 24 wk smoke-exposure groups in peripheral blood [(1.81 ± 0.19)%, (3.74 ± 0.55)%] and BALF [(7.84 ± 0.28)%, (8.01 ± 0.39)%] compared with the12 wk [(0.97 ± 0.08)%, (5.64 ± 0.54)%] and the 24 wk control group [(1.08 ± 0.10)%, (5.95 ± 0.48)%]. Ratio of Treg in BALF was higher in the smoke-exposure groups [(8.81 ± 0.49)%, (11.98 ± 0.72)%] compared with the control groups [(4.34 ± 0.28)%, (5.21 ± 0.42)%]. The level of IL-17 mRNA was increased in the 12 wk and the 24 wk smoke-exposure group in peripheral blood (25.7 ± 2.0, 33.9 ± 1.5) and in BALF (22.2 ± 1.8, 34.7 ± 4.2) compared with the 12 wk (11.3 ± 2.6, 11.6 ± 2.4) and the 24 wk (11.1 ± 2.0, 13.5 ± 3.4) control groups. Foxp3 mRNA was increased in the smoke-exposure groups (24.4 ± 2.7, 30.3 ± 2.7) compared with the control groups (12.7 ± 2.7, 14.6 ± 3.8). Th17 in smoke-exposure groups was positively correlated with counts of total cells and macrophages (r = 0.512, 0.543, all P < 0.05). An elevated expression of Th17 and Treg cells and an increase of inflammatory cytokines were evident in airway inflammation of cigarette smoke-exposed rats, suggesting that Treg was involved in the immunological regulation and Th17 was associated with the persistent inflammation in cigarette smoke-induced airway inflammation in rats.

Diabetes mellitus (DM) is caused by hyperglycemia, resulting from defective insulin secretion or function. It is widely believed that the antioxidant micronutrients obtained from plants afford significant protection against diseases like diabetes mellitus. Present study was aimed to examine the effects of Persian shallot (Allium hirtifolium Boiss) on FBS, HbA1c, insulin, triiodothyronine (T3) and thyroxine (T4) levels in type 1 diabetic rats. Thirty two male Wistar rats were divided into 4 groups of 8. The diabetic groups received 100 and 200 mg/kg Persian shallot extract, diabetic control and normal control received %0.9 saline for 30 days. At the end of treatments, fasting blood specimens were collected. The levels of FBS, HbA1c, insulin, T3 and T4 were measured. Our findings indicated that hydroalcoholic extract of Persian shallot significantly decreased serum levels of FBS and HbA1c in treated groups (in a dose dependent manner) (p<0.05). The serum levels of insulin and T3 slightly increased by Persian shallot but the T4 serum level was declined. These beneficial effects of Persian shallot extracts in diabetic rats could probably be due to the antioxidant capacity of its phenolic and diallyl disulfide content.

To realize the oxidative damage of kidney mitochondrial complex in obese rats induced by high-fat diet and investigate the protective effects of sulforaphane against the damage. Eighty-eight adult male SD rats were used, after 1 week adaptability feeding, 8 rats were selected as control group and given low-fat diet. The other 80 rats were given high-fat diet. After 2 weeks, the 32 diet-induced obesity models were choosen whose weight gain was higher than 40%. The 32 rats were randomly divided into 4 groups, i.e. high fat group, high fat+sulforaphane low dose group, high fat+sulforaphane middle dose group and high fat+sulforaphane high dose group. The rats in the sulforaphane low, middle and high dose groups were orally administered with sulforaphane 5, 10 and 20 mg/kg, all the 4 groups were kept feeding high-fat diet for 5 weeks. All rats were sacrificed and their kidneys were removed to assay the index of oxidative damages. The content of ROS (0.26 ± 0.04) and MDA((0.87 ± 0.05) U/mg) in the hight-fat group were significantly higher than those in the control group((0.20 ± 0.02),(0.57 ± 0.08) U/mg)(t values were -3.02 and -4.72, P < 0.05). The activity of T-AOC((0.43 ± 0.04) U/mg) and MMP (12.09 ± 1.56) were lower than the control group ((0.48 ± 0.04 U/mg, (16.08 ± 3.12) )(t values were 2.06 and 2.28, P < 0.05). Gavage intervention with sulforaphane, the MDA amount ((0.67 ± 0.05), (0.55 ± 0.05), (0.56 ± 0.07) U/mg) in the sulforaphane low, middle and high dose groups were lower than the hight-fat group ((0.87 ± 0.05) U/mg (t values were 3.65, 5.71 and 5.60. P < 0.05). The activity of T-AOC ((0.49 ± 0.05), (0.55 ± 0.05), (0.54 ± 0.04) U/mg), T-SOD ((61.07 ± 2.79), (55.95 ± 2.39), (60.26 ± 6.02) U/mg) and the level of MMP ((17.17 ± 2.52), (18.24 ± 2.54), (18.21 ± 3.65)) were higher than in the high-fat group ((0.43 ± 0.04) U/mg,(47.22 ± 2.43) U/mg,(12.09 ± 1.56)) (tT-AOC values were -2.36, -4.83 and -4.30; tT-SOD values were -6.37, -4.71 and -5.99; tMMP values were -2.90, -3.52 and -3.50, P < 0.05). The activity of GSH-Px in the sulforaphane low and middle dose groups ((69.12 ± 8.63), (64.43 ± 6.58) U/mg) were higher than those in the high-fat group((53.03 ± 5.70) U/mg)(t values were -3.82 and -2.71, P < 0.05). But there were no significant difference between the high dose group ((60.02 ± 7.05) U/mg) and the high-fat group (t = -1.66, P > 0.05). High-fat diet can induce the mitochondrial oxidative dysfunction in kidney, and sulforaphane shows protective effect on the kidney mitochondrial complex from oxidative damage in obese rats induced by high-fat diet.

This study aimed at assessing the effects of chamomile tea consumption on glycemic control and serum lipid profile in patients with type 2 diabetes mellitus (T2DM). This single-blind randomized controlled clinical trial was conducted on 64 individuals with T2DM (males and females) aged between 30 and 60 years. The intervention group (n = 32) consumed chamomile tea (3 g/150 mL hot water) three times per day immediately after meals for 8 weeks. The control group (n = 32) followed a water regimen for the same intervention period. Fasting blood samples, anthropometric measurements, and 3-day, 24-h dietary recalls were collected at the baseline and at the end of the trial. Data were analyzed by independent t test, paired t test, Pearson correlation test, and analysis of covariance. Chamomile tea significantly decreased concentration of HbA1C (p = 0.03), serum insulin levels (p < 0.001), homeostatic model assessment for insulin resistance (p < 0.001), total cholesterol (p = 0.001), triglyceride (p < 0.001), and low-density lipoprotein cholesterol (p = 0.05) compared with control group. No significant changes were shown in serum high-density lipoprotein cholesterol levels in both groups. Chamomile tea has some beneficial effects on glycemic control and serum lipid profile in T2DM patients.

This investigation evaluated the effect of continuous milrinone infusion on right ventriclular (RV) function during off-pump coronary artery bypass graft (OPCAB) surgery in patients with reduced RV function. Fifty patients scheduled for OPCAB, with thermodilution RV ejection fraction (RVEF) <35% after anesthesia induction, were randomly allocated to either milrinone (0.5 µg/kg/min) or control (saline) group. Hemodynamic variables and RV volumetric data measured by thermodilution method were collected as follows: after anesthesia induction (T1); 10 min after heart displacement for obtuse marginal artery anastomosis (T2); after pericardial closure (T3). Cardiac index and heart rate increased and systemic vascular resistance significantly decreased in milrinone group at T2. Initially lower RVEF of milrinone group was eventually comparable to control group after milrinone infusion. RVEF did not significantly change at T2 and T3 in both groups. RV end-diastolic volume in milrinone group consistently decreased from the baseline at T2 and T3. Continuous infusion of milrinone without a bolus demonstrated potentially beneficial effect on cardiac output and RV afterload in patients with reduced RV function during OPCAB. However, aggressive augmentation of intravascular volume seems to be necessary to maximize the effect of the milrinone in these patients. PMID:17043419

Pancreatic cancer is often accompanied by severe abdominal or back pain. It's the first study to evaluate the analgesic effect of electroacupuncture on pancreatic cancer pain. A randomized controlled trial compared electroacupuncture with control acupuncture using the placebo needle. Sixty patients with pancreatic cancer pain were randomly assigned to the electroacupuncture group (n = 30) and the placebo control group (n = 30). Patients were treated on Jiaji (Ex-B2) points T8-T12 bilaterally for 30 min once a day for 3 days. Pain intensity was assessed with numerical rated scales (NRS) before the treatment (Baseline), after 3 treatments, and 2 days follow-up. Baseline characteristics were similar in the two groups. After 3 treatment, pain intensity on NRS decreased compared with Baseline (-1.67, 95% confidence interval [CI] -1.46 to -1.87) in the electroacupuncture group; there was little change (-0.13, 95% CI 0.08 to -0.35) in control group; the difference between two groups was statistically significant (P < 0.001). Follow-up also found a significant reduction in pain intensity in the electroacupuncture group compared with the control group (P < 0.001). Electroacupuncture was an effective treatment for relieving pancreatic cancer pain. Copyright © 2013 IAP and EPC. Published by Elsevier B.V. All rights reserved.

It may be difficult to distinguish type 1 diabetes mellitus (T1DM) from type 2 diabetes mellitus (T2DM) in the pediatric population. Autoantibodies may help to differentiate both types of diabetes, but sometimes these are positive in patients with T2DM and negative in patients with T1DM. The human leukocyte antigen (HLA)-DR genotype has been associated with T1DM and with T2DM only in adults and in determined cases. To determine the differences in HLA class II allele frequencies in Mexican children with T1DM and T2DM. We included 72 children with T1DM, 28 children with T2DM, and 99 healthy controls. All were Mexican, and diabetes was diagnosed according to the clinical and laboratory criteria established by the Expert Committee on the Diagnosis and Classification of Diabetes Mellitus. The HLA-DRB1 typing was performed using polymerase chain reaction-sequence-specific oligonucleotide probe and polymerase chain reaction sequence-specific primers. We found an increased frequency of HLA-DRB1*08 and a decreased frequency of HLA-DRB1*04 in the group with T2DM vs. T1DM [p = 0.0001, odds ratio (OR) = 10.58, 95% confidence interval (CI) = 3-40.8 and p = 0.0006, OR = 0.24, 95% CI = 0.11-0.53, respectively]. No significant differences were found between HLA-DRB1 alleles in T2DM vs. controls. In the group with T1DM, there was a significantly increased frequency of the HLA-DR4 and HLA-DR3 alleles relative to controls (p = 0.0000001, OR = 3.59, 95% CI = 2.2-5.8 and p = 0.00009, OR = 4.66, 95% CI = 2.1-10.3, respectively). There are significant differences in the HLA profile in Mexican children with T1DM and T2DM. HLA typing could play a role in the differentiation between both types of diabetes in this population.

Cranial thoracic intervertebral disc herniations have been reported to be rare in dogs due to the presence of the intercapital ligament, however some studies have proposed they may not be uncommon in German Shepherd dogs. The purpose of this retrospective study was to compare cranial thoracic intervertebral disc herniations in German Shepherd dogs and other large breed dogs (control group). Medical records at the Ontario Veterinary College were searched for German Shepherd dogs and other large breed dogs that had magnetic resonance imaging studies including the T1-T9 region. For each dog and each disc space from T1-T9, three variables (compression, disc degeneration, and herniation) were recorded and graded based on review of sagittal T2-weighted images. Twenty-three German Shepherd dogs and 47 other large breed dogs met inclusion criteria. The German Shepherd dog group had higher scores than the control group for compression (P = 0.0099) and herniation (P < 0.001), but not disc degeneration (P = 0.97). In the German Shepherd dog group, intervertebral discs T2-T3 and T4-T5 had an increased risk for compression and T3-T4 had an increased risk for compression and herniation. Findings from this study indicated that German Shepherd dogs may be more likely than other large breed dogs to have spinal cord compression due to cranial thoracic disc herniations. Imaging of the cranial thoracic spine, including T2-T3, is recommended for German Shepherd dogs with T3-L3 neurological signs. © 2012 Veterinary Radiology & Ultrasound.

To examine effects on symptoms of agitation and depression in nursing home residents with moderate to severe dementia participating in a robot-assisted group activity with the robot seal Paro. A cluster-randomized controlled trial. Ten nursing home units were randomized to either robot-assisted intervention or a control group with treatment as usual during 3 intervention periods from 2013 to 2014. Ten adapted units in nursing homes in 3 counties in eastern Norway. Sixty residents (67% women, age range 62-95 years) in adapted nursing home units with a dementia diagnosis or cognitive impairment (Mini-Mental State Examination score lower than 25/30). Group sessions with Paro took place in a separate room at nursing homes for 30 minutes twice a week over the course of 12 weeks. Local nurses were trained to conduct the intervention. Participants were scored on baseline measures (T0) assessing cognitive status, regular medication, agitation (BARS), and depression (CSDD). The data collection was repeated at end of intervention (T1) and at follow-up (3 months after end of intervention) (T2). Mixed models were used to test treatment and time effects. Statistically significant differences in changes were found on agitation and depression between groups from T0 to T2. Although the symptoms of the intervention group declined, the control group's symptoms developed in the opposite direction. Agitation showed an effect estimate of -5.51, CI 0.06-10.97, P = .048, and depression -3.88, CI 0.43-7.33, P = .028. There were no significant differences in changes on either agitation or depression between groups from T0 to T1. This study found a long-term effect on depression and agitation by using Paro in activity groups for elderly with dementia in nursing homes. Paro might be a suitable nonpharmacological treatment for neuropsychiatric symptoms and should be considered as a useful tool in clinical practice.

Reduced diastolic myocardial function is an early sign of diabetic cardiomyopathy. The aim of this study was to test the hypothesis that children and adolescents with type 1 diabetes mellitus (T1D), but without other known complications, have early reduced diastolic myocardial function diagnosed with echocardiographic color tissue Doppler imaging (cTDI). cTDI examination was carried out in 173 T1D patients and 62 age-matched controls. The T1D-patients were 8-18 years old with (mean (SD)) diabetes duration of 5.6 (3.4) years and HbA1c of 8.4 (1.3). All were treated with either insulin pumps or 4-6 daily insulin injections. cTDI early (E') and late (A') peak diastolic velocities and systolic peak velocity were measured from the lateral, septal, anterior and posterior mitral annulus and from the lateral tricuspidal annulus. Myocardial diastolic function was reduced in the T1D-patients with higher peak A'-velocity and lower E'/A'-ratio in all registrations. Overall mean (SD) mitral E'/A'-ratio was 2.3 (0.5) in T1D and 2.7 (0.6) in the controls (p < 0001). The overall mitral E'/A'-ratio was negative associated with blood pressure (BP) and body mass index (BMI). Stratifying all participants into three groups according to BMI (<25, 25-75, >75 centile, respectively), the T1D had lower E'/A'-values in all stratified groups, except for in the highest BMI-group where both T1D and controls had the lowest E'/A'-ratio. Systolic function did not differ in any of the measurements. There were no associations with sex, diabetes duration, carotid artery intima-media-thickness, vessel elasticity or HbA1c. Diabetic children and adolescents using modern intensive insulin treatment had echocardiographic signs of reduced diastolic myocardial function despite short duration of disease. The reduced function was associated with higher BP and higher BMI.

Hypercholesterolemia and diabetes mellitus are known to be accompanied by reproductive dysfunction. In this study, we investigated the effects of hypercholesterolemia, hyperglycemia, and these conditions combined, on testosterone (T) and testicular luteinizing hormone/human chorionic gonadotropin (LH/hCG) binding. Sprague-Dawley rats (8 weeks old) were divided into four groups: Group 1 was the control, group 2 was fed standard chow containing 2% cholesterol (C-diet), group 3 was administered streptozotocin (STZ, 65 mg/kg, i.p.), group 4 was treated with both the C-diet and STZ. After 4 weeks, rats were sacrificed. Serum glucose was significantly higher in the STZ group (304% that of controls) and the C-diet plus STZ group (345%), but there was no difference between the C-diet group (89%) and the control group. Serum cholesterol was significantly higher in the C-diet group (206% that of controls), the STZ group (452%) and the C-diet plus STZ group (2042%). Serum T, testicular T, and LH/hCG binding were significantly lower in the C-diet group (49%, 52%, and 81% that of controls, respectively), the STZ group (15%, 32%, and 72%) and the C-diet plus STZ group (8%, 21%, and 57%). These results suggest that hypercholesterolemia is an independent risk factor for testicular dysfunction and that the reduction of serum and testicular T levels is due at least in part to a reduction in testicular LH/hCG binding in rats with hypercholesterolemia, hyperglycemia, and these conditions combined. It is further suggested that the reduction in LH/hCG binding is mainly related to a rise in serum cholesterol levels.

The aim of the present study was to evaluate the effectiveness of chlorhexidine (CHX) with an antidiscoloration system (ADS) on stain, plaque accumulation, and gingivitis. A randomized, controlled clinical trial was conducted in 26 students. After a preparatory period, the students were randomly assigned to either group P (placebo), group T1 (0.12% CHX without an ADS), or group T2 (0.12% CHX with an ADS). During the 3-week experimental period, all mechanical oral hygiene was abolished. Rinsing with 10 mL mouthwash or placebo was performed twice daily under supervision. The parameters assessed on days 0, 7, 14, and 21 included the Discoloration Index (DI), Plaque Index (PII), and Gingival Index (GI). There were no significant mean differences in the DI, PII, or GI between groups T2 and P. Significant mean differences existed in the DI between groups T2 and T1 on days 14 and 21. Significant mean differences existed in the PI between groups T2 and T1 on days 7, 14, and 21. Likewise, significant mean differences existed in the GI between groups T2 and T1 on days 14 and 21. CHX with an ADS did not prevent plaque or gingivitis development. In fact, the CHX mouthwash with an ADS showed no superior effect over placebo on oral hygiene or the prevention of gingivitis. © 2013 Wiley Publishing Asia Pty Ltd.

Introduction Type 2 diabetes mellitus (T2DM) affects more than 1.1 million Canadians aged ≥65 years. Group Medical Visits are an emerging health service delivery method. Recent systematic reviews show that they can significantly reduce glycated haemoglobin (HbA1c) levels, but Group Visits have not been evaluated within primary care. We intend to determine the clinical effectiveness, quality of life and economic implications of Group Medical Visits within a primary care setting for older people with T2DM. Methods and analysis A 2-year proof-of-concept, single-blinded (measurement team) randomised control trial to test the efficacy of Group Medical Visits in an urban Canadian primary care setting. Participants ≥65 years old with T2DM (N=128) will be equally randomised to either eight groups of eight patients each (Group Medical Visits; Intervention) or to Individual visits (Standard Care; Controls). Those administering cointerventions are not blinded to group assignment. Our sample size is based on estimates of variance (±1.4% for HbA1c) and effect size (0.9/1.4=0.6) from the literature and from our own preliminary data. Forty participants per group will provide a β likelihood of 0.80, assuming an α of 0.05. A conservative estimation of an effect size of 0.7/1.4 changes the N in the power calculation to 59 per group. Hence, we aim to enrol 64 participants in each study arm. We will use intention-to-treat analysis and compare mean HbA1c (% glycosylated HbA1c) (primary outcome) of Intervention/Control participants at 12 months, 24 months and 1 year postintervention on selected clinical, patient-rated and economic measures. Trial registration number NCT02002143. PMID:26169803

Background Strategies to improve communication in people with dementia are warranted. We examined the effect of the Sonas programme on communication ability in persons with moderate to severe dementia. Methods A 24-week 3-armed (Sonas, reading, and control group) randomized controlled trial including 120 nursing home residents with dementia was conducted; 105 completed the follow-up assessments. The main outcome was change in communication abilities measured by the Holden Communication Scale (HCS). Results We found no overall significant effect of the Sonas programme with regard to communication ability as measured by the HCS. However, an effect between the Sonas group and the reading group and between the Sonas group and the control group from T0 to T1 and T2 was found, as well as a significant improvement in communication in the Sonas group. Among people with severe dementia, the Sonas group scored significantly better on the HCS compared to the reading group after 12 weeks, but not after 24 weeks. Conclusion This study failed to document an overall effect of the Sonas programme on communication; however, the findings indicate that the Sonas programme has a significant effect on communication among those with severe dementia.

Aspirin exacerbated respiratory disease (AERD) is induced by acetylsalicylic acid (ASA) and/or nonsteroidal antiinflammatory drugs (NSAIDs). Effects of desensitization on many mediators have been examined previously, but few studies addressed the influence of desensitization on T lymphocytes and T lymphocyte-derived cytokines. This study was performed to examine peripheral blood lymphocyte (PBL) cytokine expression in aspirin-sensitive patients who have asthma before and after aspirin desensitization. In this study, the release of interleukin-2 (IL-2), interleukin-4 (IL-4), and interferon-gamma (IFN-γ) by CD4+ T lymphocytes prior to aspirin desensitization were also measured at intracellular levels, and expression of these cytokines after 1 month aspirin desensitization was evaluated. Twelve patients with AERD were included in the study. Two different control groups were formed, one consisted of 15 healthy people and second 12 aspirin tolerant asthmatic (ATA) patients using aspirin. A blood sample was collected prior to desensitization, and the tests were repeated by taking a second blood sample 1 month after the 4-day desensitization treatment. The proportion of lymphocytes secreting IFN-γ in the study group was 15.61 ± 4.40 % before desensitization and 15.08 ± 5.89 % after desensitization. The rate of IFN-γ secreting CD4+ T lymphocytes was 20.51 ± 4.41 % in the normal control group and 16.07 ± 5.7 % in the ATA group (p = 0.021). The ratio of CD4+ T lymphocyte secreting IFN-γ was reduced in patients with AERD before desensitization compared to normal control group (p = 0.040). The levels of IL-2, IL-4, and the subsets of lymphocyte were not different before and after desensitization compared to control groups.

To evaluate whether balance training after total knee replacement surgery improves functional outcomes and to determine whether postoperative balance is associated with mobility. A prospective intervention study and randomized controlled trial with an intention-to-treat analysis. The rehabilitation center of a university-based teaching hospital. A total of 130 patients with knee osteoarthritis who had undergone total knee replacement surgery were recruited to attend an outpatient rehabilitation program. They were randomly allocated to additional balance rehabilitation and functional rehabilitation groups. During the eight-week outpatient rehabilitation program, both groups received general functional training. Patients in the balance rehabilitation group received an additional balance-based rehabilitation program. The functional reach test, single-leg stance test, 10-m walk test, Timed Up and Go Test, timed chair-stand test, stair-climb test, and Western Ontario and McMaster Universities Osteoarthritis Index were measured at baseline, eight weeks (T(1)), and 32 weeks (T(2)). The balance rehabilitation group patients demonstrated significant improvement in the results of the functional reach test at T(1) (37.6 ±7.8 cm) and T(2) (39.3 ±9.7 cm) compared with the baseline assessment (11.5 ±2.9 cm) and Timed Up and Go Test at T(1) (8.9 ±1.2 seconds) and T(2) (8.0 ±1.9 seconds) compared with the baseline assessment (12.5 ±1.8 seconds). Moreover, the balance rehabilitation group patients exhibited significantly greater improvements in balance and mobility than did the functional rehabilitation group patients (all P < 0.001). Furthermore, improved balance was significantly associated with improved mobility at T(2). Postoperative outpatient rehabilitation with balance training improves the balance, mobility, and functional outcomes in patients with knee osteoarthritis after total knee replacement. © The Author(s) 2014.

Objectvie: To investigate the effects of secreting cytokines interferon-gamma (IFN-γ) and interleukin-17 (IL-17) of T helper 1 cells (Th1) and T helper 17 cells (Th17) on the peripheral blood and alveolar bone destruction, so as to provide a new explanation for cellular immunity-mediated alveolar bone destruction. Methods: Eighteen eight-week-old male Sprague-Dawley rats were divided, randomly and equally, into 3 groups: lipopolysaccharide (LPS) group, ligation group and normal control group. In the LPS group, Escherichia coli LPS was injected into the alveolar mucosa on the buccalmedian site of the left upper first molar, while the right upper first molar was injected with equal volume of physiological saline as self-controls. The injections were performed every other day for four times totally. In the ligation group, the left upper first molars were ligatured with 0.2 mm orthodontic cords, while the right upper first molars were left untreated as self-controls, and supplemented with high-sugar diet to promote the periodontitis status. The rats in normal control group were fed normally. The concentrations of IFN-γ and IL-17 in peripheral blood were measured using enzyme linked immunosorbent assay (ELISA) method at the fourth week after the start of injection and at the eighth week after ligation. The histological of periodontal tissues were observed after hematoxylin-eosin (HE) staining and osteoclast count was performed under light microscope. The histological of osteoclasts were observed after tartrate-resistant acid phosphatase (TRAP) staining. Expression of IFN-γ and IL-17 were detected by immunohistochemical assay. Results: The concentrations of IFN-γ in peripheral blood of LPS group [(185.0±50.7) ng/L] and ligation group [(202.9±60.4) ng/L] were significantly higher than that of normal control group [(106.3±17.2) ng/L]( P< 0.05). Meanwhile, histological examination showed inflammatory cells infiltration in the gingival epithelium, the height reduction of alveolar bone accompanied with absorption lacuna. There were significantly higher HE and TRAP stained osteoclasts in LPS group (9.50±1.05) and ligation group (10.83±1.17) than that in controlgroup (0.33±0.52)( P< 0.05). Moreover, the expressions of IL-17 in alveolar bone absorption area of LPS group and ligation group were significantly stronger than that in control group ( P< 0.05). Conclusions: The rat models of experimental periodontitis and alveolar bone resorption could be successfully established by means of ligationand LPS injection, respectively. The periodontal inflammatory responses were related to secreting cytokines IFN-γ and IL-17 of Th1 and Th17 cells, while Th17 cells might exert a positive effect on alveolar bone destruction.

Smoking prevalence rates among Dutch children increase rapidly after they transit to secondary school, in particular among children with a low socioeconomic status (SES). Web-based, computer-tailored programs supplemented with prompt messages may be able to empower children to prevent them from starting to smoke when they transit to secondary school. The main aim of this study is to evaluate whether computer-tailored feedback messages, with and without prompt messages, are effective in decreasing children's smoking intentions and smoking behavior after 12 and 25 months of follow-up. Data were gathered at baseline (T0), and after 12 months (T1) and 25 months (T2) of follow-up of a smoking prevention intervention program called Fun without Smokes. A total of 162 schools were randomly allocated to a no-intervention control group, an intervention prompt group, or an intervention no-prompt group. A total of 3213 children aged 10 to 12 years old participated in the study and completed a Web-based questionnaire assessing their smoking intention, smoking behavior, and sociocognitive factors, such as attitude, social influence, and self-efficacy, related to smoking. After completion, children in the intervention groups received computer-tailored feedback messages in their own email inbox and those messages could be accessed on the intervention website. Children in the prompt group received prompt messages, via email and short message service (SMS) text messaging, to stimulate them to reuse the intervention website with nonsmoking content. Multilevel logistic regression analyses were performed using multiple imputations to assess the program effects on smoking intention and smoking behavior at T1 and T2. A total of 3213 children participated in the Fun without Smokes study at T0. Between T0 and T1 a total of 1067 children out of the original 3213 (33.21%) dropped out of the study. Between T0 and T2 the number of children that did not participate in the final measurement was 1730 out of the original 3213 (53.84%). No significant program effects were observed for any of the intervention groups compared to the control group at T1 for the intention to engage in smoking-prompt, OR 0.67 (95% CI 0.30-1.50), no-prompt, OR 0.76 (95% CI 0.34-1.67)-or for smoking behavior-prompt, OR 1.13 (95% CI 0.13-9.98), no-prompt, OR 0.50 (95% CI 0.04-5.59). Similar nonsignificant program effects were found at T2 for the intention to start smoking-prompt, OR 0.78 (95% CI 0.26-2.32), no-prompt, OR 1.31 (95% CI 0.45-3.82)-and smoking behavior-prompt, OR 0.53 (95% CI 0.12-2.47), no-prompt, OR 1.01 (95% CI 0.24-4.21). This study showed that the Web-based, computer-tailored feedback messages with and without prompt messages were not effective in modifying children's smoking intentions and smoking behavior as compared to no information. Future smoking prevention interventions are recommended to start closer to the age of actual smoking uptake. Furthermore, future studies on Web-based, computer-tailored smoking prevention programs should focus on assessing and controlling exposure to the educational content and the response to the prompt messages.

Aim: This study was carried out to evaluate groundnut haulms (GNH) as alternate feed source by its incorporation and assessment in terms of feed intake and growth performance in the diets of broilers. Materials and Methods: A total of 240 1-day-old Cobb-400 broiler chicks were randomly assigned to four dietary treatments each with three replicates (n=60). Experimental Birds in group T1 were fed with conventional feed while birds in T2, T3, T4 were fed containing 2%, 4%, and 6% of GNH replacing maize and soyabean on iso-nitrogenous basis. Results: Feed intake increases significantly (p>0.05) with increasing level of GNH in the diets of experimental birds. Highest feed intake was recorded in T4 (6% GNH), followed by T3 (4% GNH) than T2 (2% GNH) and T1 (control). Birds fed GNH gained significantly (p<0.05) higher body weight than birds fed the control diet. Birds in T4 [6% GNH] gained highest body weight, followed by T3 (4% GNH) than T2 (2% GNH) and T1 (control). However, feed conversion ratio (FCR) remained non-significant for all treatment groups. Conclusion: On the basis of the results of this study, it is concluded that supplementation of GNH can successfully replace costly ingredients like maize and soybean meal in the diets of broiler birds up to the level of 6 percent of concentrate mixture without any harmful effects on feed intake, growth and FCR.

Haptoglobin (Hp), serum amyloid A (SAA), C-reactive protein (CRP), white blood cells (WBC), reactive oxygen metabolites (ROMs), the antioxidant barrier (Oxy-adsorbent) and thiol groups of plasma compounds (SHp) were measured in ten dogs that had been transported a distance of about 230 km within 2 h (experimental group) and in ten dogs that had not been subjected to road transportation (control group). Blood was collected via cephalic venipuncture before road transportation (T0), after road transportation (T1), and more than 6 (T6) and 24 (T24) hours after road transportation in the experimental group (Group A) and at the same time points in the control group (Group B). The GLM (general linear model) Repeated Measures procedure showed a significant difference between the two groups (P<0.0001) and a significant rise (P<0.0001) in the concentrations of Hp, SAA, CRP, WBC, ROMs, Oxy-adsorbent and SHp after road transportation in Group A, underlining that physiological and homeostatic mechanisms are modified differently at various sampling times.

The liver is a central organ for the metabolism of iron and manganese and the places where those metals are commonly deposited overlap in the brain. To elucidate the relationship between pallidal T 1 hyperintensity and iron deposition in the deep gray matter of liver cirrhosis patients using quantitative susceptibility mapping (QSM). Retrospective case-control study SUBJECTS: In all, 38 consecutive liver cirrhosis patients who received brain magnetic resonance imaging (MRI) as pretransplant evaluation. QSM was reconstructed from 3D multi- or single-echo phase images at 3T. T 1 -weighted images were used for the assessment of pallidal hyperintensity and pallidal index (PI). Patients were divided into two groups according to the presence of pallidal hyperintensity by consensus of two radiologists. Susceptibility values were acquired for five deep gray matter structures. QSM measures were compared between two groups using the t-test. We also calculated Pearson correlations between QSM measures and PI. In all, 26 patients showed pallidal hyperintensity (T 1 h group) and 12 did not (T 1 n group). The susceptibility of the globus pallidus (GP) in the T 1 h group (120.6 ± 38.1 ppb) was significantly lower than that in the T 1 n group (150.0 ± 35.2, P = 0.030). The susceptibility of the dentate nucleus (DN) in the T 1 h group (88.1 ± 31.0) was significantly lower than that in the T 1 n group (125.6 ± 30.6, P = 0.001). Negative correlation between the susceptibility of GP (r = -0.37, P = 0.022) and the PI, and between DN (r = -0.43, P < 0.001) and the PI was found. Liver cirrhosis patients with pallidal T 1 hyperintensity had lower susceptibility values in the GP and DN than those without it. This suggests a possible interaction between iron and manganese in the brains of liver cirrhosis patients. 3 Technical Efficacy: Stage 3 J. Magn. Reson.

We assessed the antioxidant activity of dexmedetomidine (DEX) during an ischemic period in a rat model of testicular torsion/detorsion (T/DT) by using biochemical and histopathological methods. Wistar Albino male rats weighing 250-300 g were divided into three groups: sham (group S, n = 7); torsion/detorsion (group T/DT, n = 7), and DEX treatment (group DEX, n = 7). In the T/DT group, right testes were rotated 720 degrees for 1 h. Group S served for normal basal values. Rats in group T/DT were operated to make T/DT, this group served as a control group. Group DEX received intraperitoneal DEX 10 microg . kg(-1) after the 30-min torsion period. For measurement of total antioxidant enzyme activities and malondialdehyde (MDA) levels, testes of 7 animals in each group were excised after 4 h of reperfusion. Germ cell apoptosis was evaluated using the apoptosis protease-activating factor 1 (APAF-1) antibody in all groups and also on the expressions of endothelial nitric oxide synthase (eNOS) and inducible nitric oxide synthase (iNOS) were assessed within the bilateral testes. Mean MDA levels in group T/DT were significantly higher than in groups S and DEX (p < 0.05). There were also significant decreases in mean total antioxidant activities in group T/DT when compared to groups S and DEX (p < 0.05). These values were significantly higher in group DEX than group T/DT. Germ cell apoptosis, eNOS and iNOS levels were significantly higher in group T/DT when compared to groups S and DEX (p < 0.05). DEX treatment has potential biochemical and histopathological benefits by preventing ischemia/reperfusion-related cellular damage in an experimental testicular torsion model. Preference of DEX for anesthesia during the detorsion procedure may attenuate ischemia-reperfusion injury. Copyright 2010 S. Karger AG, Basel.

Detailed studies of correlation between HIV-M.tb co-infection and hierarchy declines of CD8+/CD4+ T-cell counts and IFN-γ responses have not been done. We conducted case-control studies to address this issue. 164 HIV-1-infected individuals comprised of HIV-1+ATB, HIV-1+LTB and HIV-1+TB- groups were evaluated. Immune phenotyping and complete blood count (CBC) were employed to measure CD4+ and CD8+ T-cell counts; T.SPOT.TB and intracellular cytokine staining (ICS) were utilized to detect ESAT6, CFP10 or PPD-specific IFN-γ responses. There were significant differences in median CD4+ T-cell counts between HIV-1+ATB (164/μL), HIV-1+LTB (447/μL) and HIV-1+TB- (329/μL) groups. Hierarchy low CD4+ T-cell counts (<200/μL, 200-500/μL, >500/μL) were correlated significantly with active TB but not M.tb co-infection. Interestingly, hierarchy low CD8+ T-cell counts were not only associated significantly with active TB but also with M.tb co-infection (P<0.001). Immunologically, HIV-1+ATB group showed significantly lower numbers of ESAT-6-/CFP-10-specific IFN-γ+ T cells than HIV-1+LTB group. Consistently, PPD-specific IFN-γ+CD4+/CD8+ T effector cells in HIV-1+ATB group were significantly lower than those in HIV-1+LTB group (P<0.001). Hierarchy low CD8+ T-cell counts and effector function in HIV-1-infected individuals are correlated with both M.tb co-infection and active TB. Hierarchy low CD4+ T-cell counts and Th1 effector function in HIV-1+ individuals are associated with increased frequencies of active TB, but not M.tb co-infection.

Background The studio di intervento nel decadimento vascolare lieve (IDEALE study) was an open multicenter Italian study, the aim of which was to assess the effectiveness and safety of oral citicoline in elderly people with mild vascular cognitive impairment. Methods The study was performed in 349 patients. The active or citicoline group was composed of 265 patients and included 122 men and 143 women of mean age 79.9 ± 7.8 years selected from six Italian regions. Inclusion criteria were age ≥ 65 years, Mini-Mental State Examination (MMSE) score ≥ 21, subjective memory complaints but no evidence of deficits on MMSE, and evidence of vascular lesions on neuroradiology. Those with probable Alzheimer’s disease were excluded. The control group consisted of 84 patients, including 36 men and 48 women of mean age 78.9 ± 7.01 (range 67–90) years. Patients included in the study underwent brain computed tomography or magnetic resonance imaging, and plasma dosage of vitamin B12, folate, and thyroid hormones. Functional dependence was investigated by scores on the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales, mood was assessed by the Geriatric Depression Scale (GDS), and behavioral disorders using the Neuropsychiatric Inventory scale. Comorbidity was assessed using the Cumulative Illness Rating Scale. An assessment was made at baseline (T0), after 3 months (T1), and after 9 months (T2, ie, 6 months after T1). The main outcomes were an improvement in MMSE, ADL, and IADL scores in the study group compared with the control group. Side effects were also investigated. The study group was administered oral citicoline 500 mg twice a day throughout the study. Results MMSE scores remained unchanged over time (22.4 ± 4 at T0; 22.7 ± 4 at T1; 22.9 ± 4 at T2), whereas a significant difference was found between the study and control groups, both in T1 and in T2. No differences were found in ADL and IADL scores between the two groups. A slight but not statistically significant difference was found in GDS score between the study and control groups (P = 0.06). No adverse events were recorded. Conclusion: In this study, citicoline was effective and well tolerated in patients with mild vascular cognitive impairment. Citicoline activates biosynthesis of phospholipids in neuronal membranes, increases brain metabolism as well as norepinephrine and dopamine levels in the central nervous system, and has neuroprotective effects during hypoxia and ischemia. Therefore, citicoline may be recommended for patients with mild vascular cognitive impairment. PMID:23403474

Currently many TKA protocols rely on multimodal analgesic protocols with patient-controlled analgesia systems that administer opioids through a patient controlled IV infusion pump, in addition to concomitant peripheral nerve blocks and local anesthetics. Although effective, PCA IV opioids do not provide optimal results with fast track rehabilitation protocols. The present is a retrospective study comparing the novel sublingual sufentanil PCA system (SSTS) to our standard of care foreseeing continuous femoral nerve block (cFNB) within a multimodal analgesic in a TKA fast-track protocol. The study evaluated 95 patients on SSTS (SSTS group) and 87 on cFNB (cFNB/control group) and collected data on numeric rating scores for pain from day 1-3 after surgery (T1, T2, T3), both at rest (NRS) and during movement (mNRS), patient's ability to walk, need for supplementary analgesia (rescue dose), occurrence of adverse effects, length of hospital stay, and usability rating for SSTS by both patients and hospital staff. NRS at rest was lower in the cFNB than in the SSTS group for all 3 days after surgery, whereas mNRS scores were lower in the SSTS group at all time points measured. Adverse effects were significantly fewer among patients of the SSTS group (6% patients) than those of the cFNB (74% patients) (p <  0.001). Rescue doses were needed by 5% of SSTS patients vs 60% of cFNB. The fewer adverse events and lower pain scores for the SSTS group were associated to a notably better ability to ambulate, with all patients (100%) of the SSTS group being able to stand and walk for 10 m from T1 on; patients in the cFNB group showed a slower recovery with only 40% being able to stand and walk on T1, 70% on T2 and 85% on T3. All patients of the SSTS group had a length of stay of 4 days (day of surgery plus 3 after) as foreseen by the fast track protocol, in comparison only 36% of cFNB. Lastly, patient and nursing staff judged SSTS easy to use. Our experience suggests that SSTS is a valuable strategy for routine postoperative analgesia following TKA in the context of a multimodal analgesic approach within the fast-track setting.

We aimed to evaluate the correlation of the monocyte chemoattractant protein 1 (MCP-1) A-2518G polymorphism with type 2 diabetes mellitus (T2DM) and vascular complications in T2DM, to aid in understanding its role in pathogenesis. A total of 150 T2DM patients and 50 healthy controls (group A) were enrolled. The T2DM patients were divided into three groups based on the absence of complications (group B) presence of microvascular disease (group C) or macrovascular disease (group D). DNA of all enrolled subjects was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for the MCP-1 A-2518G polymorphism. Serum MCP-1 levels were measured by an enzyme-linked immunosorbent assay (ELISA). Participants in group D had increased serum MCP-1 levels relative to group B, group C, and group A (all p<0.01). Compared with group A, the frequencies of the MCP-1 A-2518G G/G genotype and G allele were significantly higher in group C and group D (all p<0.05). In contrast to group B, group C had higher frequencies of the G/G genotype and G allele, while group D had higher G allele frequencies (all p<0.05). Logistic regression analysis showed that lower body-mass index (BMI) and free cholesterol (FC), as well as higher high-density lipoprotein cholesterol (HDL-C) levels may be the protective factors for T2DM, while higher levels of triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and G/G genotype frequency were independent risk factors for T2DM. Our data indicates a correlation between the MCP-1 A-2518G polymorphism with macrovascular complications in T2DM patients; lower BMI and FC, as well as higher HDL-C levels may be the protective factors for T2DM, while higher levels of TG, LDL-C, and G/G genotype frequency were independent risk factors for T2DM.

Background: The real mechanism for Thevetia peruviana poisoning remains unclear. Cholinergic activity is important for cardiac function regulation, however, the effect of T. peruviana on cholinergic activity is not well-known. Objective: To study the effect of the acute administration of an aqueous extract of the seed kernel of T. peruviana on the acetylcholine esterase (AChE) activity in CD1 mice as well its implications in the sub-chronic toxicity of the extract. Materials and Methods: A dose of 100 mg/kg of the extract was administered to CD1 mice and after 7 days, serum was obtained for ceruloplasmin (CP) quantitation and liver function tests. Another group of mice received a 50 mg/kg dose of the extract 3 times within 1 h time interval and AChE activity was determined for those animals. Heart tissue histological preparation was obtained from a group of mice that received a daily 50 mg/kg dose of the extract by a 30-days period. Results: CP levels for the treated group were higher than those for the control group (Student's t-test, P ≤ 0.001). AChE activity in the treated group was significantly higher than the control group (Tukey test, control vs. T. peruviana, P ≤ 0.001). Heart tissue histological preparations showed leukocyte infiltrates and necrotic areas, consistent with infarcts. Conclusion: The increased levels of AChE and the hearth tissue infiltrative lesions induced by the aqueous seed kernel extract of T. peruviana explains in part the poisoning caused by this plant, which can be related to an inflammatory process.

Twenty pregnant ewes were selected and classified into two groups. The first group received subcutaneous selenium supplementation (0.1 mg of sodium selenite/kg BW) at the 8th and 5th weeks before birth and 1st week after birth while the other was control group without selenium injection. Maternal plasma and serum samples were collected weekly from the 8th week before birth until the 8th week after birth and milk samples were taken from ewes weekly, while plasma and serum samples were collected at 48 hours, 1st, 2nd, 3rd, 5th, and 8th weeks after birth from the newborn lambs. Results demonstrated significant positive relationship between maternal plasma selenium and serum T3 in supplemented and control ewes (r = 0.69 to 0.72, P < 0.05). There was significant (P < 0.001) increase in T3 in supplemented ewes and their lambs until the 8th week after birth. There was positive relationship between milk, selenium concentration, and serum T3 in the newborn lambs of the supplemented group (r = 0.84, P < 0.01), while the relationship was negative in the control one (r = −0.89, P < 0.01). Muscular and thyroid pathological changes were independent of selenium supplementation. Selenium supplementation was important for maintaining T3 in ewes and newborn lambs until the 8th week after birth. PMID:24660087

The aim of the present study was to examine the effect of Greek traditional dances on the improvement of old people's quality of life. A hundred and eleven subjects (75 women and 36 men) 60-91 years old, were divided into an experimental group (n=76) which participated in Greek traditional dances and a control group (n=35) which was discussing and watching television, both for 1h. The Subjective Exercise Experiences Scale [McAuley, E., Courneya, K., 1994. The Subjective Exercise Experiences Scale (SEES): development and preliminary validation. Journal of Sport and Exercise Psychology 16, 163-177] was used to measure positive well-being, psychological distress, and fatigue and the State-Trait Anxiety Inventory [Spielberger, C.D., Gorsuch, R., Lushene, R., 1970. Manual for the State-trait Anxiety Inventory. Consulting Psychologists, Palo Alto] to measure state and trait anxiety respectively. Correlational analyses, between the various measures taken postdance, showed that the overall set of relations between the SEES subscales and the SAI-Y1 subscale supports the criterion-related validity of this measure of exercise-induced psychological responses. The independent groups t-tests showed that the control group in comparison to experimental group, at rest as well as on the second measurement, has significantly higher levels of state anxiety (t=-4.45, p<0.001 &t=-6.56, p<0.001), psychological distress (t=-4.30, p<0.001 &t=-5.46, p<0.001), and fatigue (t=-3.16, p<0.01 &t=-3.46, p<0.001), while it has significantly lower levels of positive well-being (t=4.23, p<0.001 &t=6.90, p<0.001). After dancing approximately 63% of maximum heart rate of experimental group was activated, while from paired t-tests significant decreases in state anxiety (t=5.02, p<0.001) and psychological distress (t=3.14, p<0.01) were observed, as well as significant increases in positive well-being (t=-4.44, p<0.001) and fatigue (t=-2.15, p<0.05). On the other hand, no significant difference in control group was observed. Consequently, Greek traditional dances may be used as a functional psycho-physical activity, to produce both physical and mental benefits for elderly individuals. (c) 2008 Elsevier Ltd.

The purpose of this study was to examine the effects of aroma hand massage on pain, state anxiety and depression in hospice patients with terminal cancer. This study was a nonequivalent control group pretest-posttest design. The subjects were 58 hospice patients with terminal cancer who were hospitalized. Twenty eight hospice patients with terminal cancer were assigned to the experimental group (aroma hand massage), and 30 hospice patients with terminal cancer were assigned to the control group (general oil hand massage). As for the experimental treatment, the experimental group went through aroma hand massage on each hand for 5 min for 7 days with blended oil-a mixture of Bergamot, Lavender, and Frankincense in the ratio of 1:1:1, which was diluted 1.5% with sweet almond carrier oil 50 ml. The control group went through general oil hand massage by only sweet almond carrier oil-on each hand for 5 min for 7 days. The aroma hand massage experimental group showed more significant differences in the changes of pain score (t=-3.52, p=.001) and depression (t=-8.99, p=.000) than the control group. Aroma hand massage had a positive effect on pain and depression in hospice patients with terminal cancer.

To investigate the metabolic differences in hippocampi of patients with juvenile myoclonic epilepsy (JME) and healthy controls using magnetic resonance spectroscopy (MRS). A 3D multivoxel SE 135 MRS study on 1.5 T scanner of both hippocampi was performed in 17 patients with JME and normal brain MRI and in 19 age and sex matched controls. Three dominant signals were measured: Choline (Cho), Creatine (tCr) and N-Acetylaspartate (NAA) and expressed as ratios of Cho:tCr, NAA:tCr, NAA:Cho and NAA:(Cho+tCr). Metabolite ratios in head, body and tail of each hippocampus in the JME group of patients were compared with ratios from corresponding structures in the control group. We found a significant difference in metabolite ratios of both hippocampi between the JME and the control groups. We detected significant differences of Cho:tCr in the head, NAA:tCr in the head, body and tail, NAA:Cho and NAA:(Cho+tCr) in the body and tail of the left hippocampus, and NAA:Cho and NAA:(Cho+tCr) in the body and tail of the right hippocampus. Although not previously recognized as a part of the epileptogenic network, our results suggest that the hippocampus, well recognized as a key player in focal epilepsies, may have a certain role in the pathogenesis of JME.

To determine whether lens induced myopia in chicks can be reversed or reduced by wearing myopia progression control lenses of the same nominal (central) power but different peripheral designs. Newly hatched chicks wore -10D Conventional lenses unilaterally for 7 days. The myopic chicks were then randomly divided into three groups: one fitted with Type 1 myopia progression control lenses, the second with Type 2 myopia progression control lenses and the third continued to wear Conventional lenses for seven more days. All lenses had -10D central power, but Type 1 and Type 2 lenses had differing peripheral designs; +2.75D and +1.32D power rise at pupil edge, respectively. Axial length and refractive error were measured on Days 0, 7 and 14. Analyses were performed on the mean differences between treated and untreated eyes. Refractive error and axial length differences between treated and untreated eyes were insignificant on Day 0. On Day 7 treated eyes were longer (T1; 0.44 ± 0.07 mm, T2; 0.27 ± 0.06 mm, C; 0.40 ± 0.06 mm) and more myopic (T1; -9.61 ± 0.52D, T2; -9.57 ± 0.61D, C; -9.50 ± 0.58D) than untreated eyes with no significant differences between treatment groups. On Day 14 myopia was reversed (+2.91 ± 1.08D), reduced (-3.83 ± 0.94D) or insignificantly increased (-11.89 ± 0.79D) in treated eyes of Type 1, Type 2 and Conventional treated chicks respectively. Relative changes in axial lengths (T1; -0.13 ± 0.09 mm, T2; 0.36 ± 0.09 mm, C; 0.56 ± 0.05 mm) were consistent with changes in refraction. Refractive error differences were significant for all group comparisons (p < 0.001). Type 1 length differences were significantly different from Conventional and Type 2 groups (p < 0.001). Myopia progression control lens designs can reverse lens-induced myopia in chicks. The effect is primarily due to axial length changes. Different lens designs produce different effects indicating that lens design is important in modifying refractive error. © 2017 The Authors.

Numerous adaptations of the maternal immune system are necessary during pregnancy to maintain immunological tolerance to the semi-allogeneic fetus. Several complications of pregnancy have been associated with dysregulation of these adaptive mechanisms. While gestational diabetes mellitus (GDM) has been associated with upregulation of circulating inflammatory factors linked to innate immunity, polarisation of the adaptive immune system has not been extensively characterised in this condition. We aimed to characterise pro- and anti-inflammatory CD4 + (T helper [Th]) T cell subsets in women with GDM vs women without GDM (of similar BMI), during and after pregnancy, and examine the relationship between CD4 + subsets and severity of GDM. This is a prospective longitudinal case-control study of 55 women with GDM (cases) and 65 women without GDM (controls) at a tertiary maternity hospital. Quantification of proinflammatory (Th17, Th17.1, Th1) and anti-inflammatory (regulatory T cell [Treg]) CD4 + T cell subsets was performed on peripheral blood at 37 weeks gestation and 7 weeks postpartum, and correlated with clinical characteristics and measures of blood glucose. Women with GDM had a significantly greater percentage of Th17 (median 2.49% [interquartile range 1.62-4.60] vs 1.85% [1.13-2.98], p = 0.012) and Th17.1 (3.06% [1.30-4.33] vs 1.55% [0.65-3.13], p = 0.006) cells compared with the control group of women without GDM. Women with GDM also had higher proinflammatory cell ratios (Th17:Treg, Th17.1:Treg and Th1:Treg) in pregnancy compared with the control group of women without GDM. In the control group, there was a statistically significant independent association between 1 h glucose levels in the GTT and Th17 cell percentages, and also between 2 h glucose levels and percentage of Th17 cells. The percentage of Th17 cells and the Th17:Treg ratio declined significantly after delivery in women with GDM, whereas this was not the case with the control group of women. Nevertheless, a milder inflammatory phenotype persisted after delivery (higher Th17:Treg ratio) in women with GDM vs women without. Dysregulation of adaptive immunity supports a novel paradigm of GDM that extends beyond hyperglycaemia and altered innate immunity.

Mindfulness-based meditation practices involve various attentional skills, including the ability to sustain and focus ones attention. During a simple mindful breathing practice, sustained attention is required to maintain focus on the breath while cognitive control is required to detect mind wandering. We thus hypothesized that regular, brief mindfulness training would result in improvements in the self-regulation of attention and foster changes in neuronal activity related to attentional control. A longitudinal randomized control group EEG study was conducted. At baseline (T1), 40 meditation naïve participants were randomized into a wait list group and a meditation group, who received three hours mindfulness meditation training. Twenty-eight participants remained in the final analysis. At T1, after eight weeks (T2) and after 16 weeks (T3), all participants performed a computerized Stroop task (a measure of attentional control) while the 64-channel EEG was recorded. Between T1 and T3 the meditators were requested to meditate daily for 10 min. Event-related potential (ERP) analysis highlighted two between group effects that developed over the course of the 16-week mindfulness training. An early effect at left and right posterior sites 160–240 ms post-stimulus indicated that meditation practice improved the focusing of attentional resources. A second effect at central posterior sites 310–380 ms post-stimulus reflects that meditation practice reduced the recruitment of resources during object recognition processes, especially for incongruent stimuli. Scalp topographies and source analyses (Variable Resolution Electromagnetic Tomography, VARETA) indicate relevant changes in neural sources, pertaining to left medial and lateral occipitotemporal areas for the early effect and right lateral occipitotemporal and inferior temporal areas for the later effect. The results suggest that mindfulness meditation may alter the efficiency of allocating cognitive resources, leading to improved self-regulation of attention. PMID:22363278

To observe the effect of resolving phlegm method (RPM) on fibrinolytic status in non-alcoholic steatohepatitis (NASH) patients of phlegm blood-stasis (PBS) syndrome type. Sixty-two patients were randomly assigned to 2 groups, namely the treated group (n = 34) treated with Chinese herbs for resolving phlegm and dampness, smoothing liver and gallbladder, promoting blood circulation and removing blood stasis (composition: Indigo Naturalis 10 g, Alumen 3 g, Semen Cassiae 15 g, Fructus Crataegi 15 g, vinegar prepared Radix Bupleuri 10 g, Radix Curcumae 10 g, Radix Salviae Miltiorrhizae 12 g, Herba Lycopi 12 g, talc 12 g and Radix Glycyrrhizae 2 g), one dose twice per day orally, and the control group (n = 28) with ursodeoxycholic acid tablet (UAT) 150 mg three times per day. The treatment course for both groups was 12 weeks. Liver function (ALT, AST, ALP), insulin resistance (IR) index represented by homeostasis model-IR (HOMA-IR) and insulin (Ins), levels of tissue plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-1), as well as main symptoms and physical signs were assessed before and after treatment. (1) Compared with those before treatment, levels of ALT, AST, HOMA-IR, t-PA, PAl-1 and main symptoms were all improved in the treated group (P < 0.05 or P < 0.01); (2) There was significant difference in ALP, HOMA-IR, t-PA and PAI-1 between the treated group and the control group (P < 0.05 or P < 0.01); (3) The improvement in liver function related indexes in the control group was mainly the level of ALT, t-PA (P < 0.01), and also shown on HOMA-IR, Ins and PAI-1. RPM could effectively improve liver function and fibrinolytic status. Its effect was better than that of UAT.

Diabetes self-care activities, like, healthy diet, regular exercise, self-monitoring of blood glucose, and rational use of medicines are considered to play a vital role in establishing euglycemia. Health literacy among type 2 diabetes mellitus (T2DM) patients in Pakistan is very low, which is the most likely cause for poor clinical outcomes. This study is designed to investigate the impact of pharmacist-led educational intervention on glycemic control, self-care activities and disease knowledge among T2DM patients in Pakistan. In this randomized controlled trail, effectiveness of a 6-month pharmacist-led educational intervention will be examined on glycemic control, diabetes self-care activities and disease knowledge of 80 adult T2DM patients (age >30 years) with poorly controlled T2DM (HbA1c> 7%), after randomizing them into intervention and control groups, at diabetes care clinic of Capital Hospital Islamabad, Pakistan. The primary outcome is change in patients' HbA1c, whereas, changes in self-care activities and patients' disease knowledge are the secondary outcomes. After baseline assessment of their self-care activities and disease knowledge by using validated Urdu versions of Diabetes Self-management Questionnaire (DSMQ) and Diabetes Knowledge Questionnaire (DKQ), respectively, interventional group patients will be supplemented with a face-to-face pharmacist-led educational intervention, whereas, the control group will receive usual care. Intervention arm patients will be educated successively at their first follow-up visit (12th week) and telephonically after every 4 weeks. All assessments will be made at baseline and end of trail for both intervention and control groups. Multivariate general linear model will be applied to analyze the effects of the intervention. Glycemic control in T2DM patients requires optimum self-care activities. This study is an attempt to improve self-care behaviors among poorly controlled T2DM patients who are at higher risk of diabetes-associated late complications.

Gastrointestinal tract microbiota, particularly bacterial microflora, seem to have a different qualitative and quantitative composition in both type 1 (T1DM) and type 2 diabetes (T2DM) mellitus cases as compared to non-diabetic individuals. So far, there are no data from diabetes research concerning the prevalence of fungi, particularly the most common genus, i.e. Candida, which are important components of human colon microflora. We aimed to examine whether there are quantitative changes of Candida fungi in the feces of patients with T1DM and T2DM as compared to healthy controls. Overall, we included 44 diabetic patients (27 patients with T1DM and 17 with T2DM) as well as 17 healthy, non-diabetic controls. Feces and blood samples were collected from all study individuals. DNA was isolated from fecal samples and quantitative real time PCR (qPCR) was applied in order to determine the number of fungal cells. Statistical association with selected clinical and biochemical features was examined. There was a difference in the amount of Candida in the feces among the three examined groups (p = 0.007). Candida spp. populations in T1DM and T2DM subjects were larger as compared to controls (p = 0.017 and p = 0.037, respectively). However, no difference was found between T1DM and T2DM. No association was identified between the quantity of fungi and examined patients' characteristics, except for negative correlation with blood lipid parameters in T2DM group. Candida fungi appear to be more prevalent in the feces of patients with T1DM and T2DM. Their amount seems to be associated with serum lipids in T2DM patients. This initial finding requires further confirmation.

Introduction Brain/Computer Interaction (BCI) devices are designed to alter neural signals and, thereby, mental activity. This study was a randomized, waitlist (TAU) controlled trial of a BCI, EEG neurofeedback training (NF), in patients with chronic PTSD to explore the capacity of NF to reduce PTSD symptoms and increase affect regulation capacities. Study Design 52 individuals with chronic PTSD were randomized to either NF (n = 28) or waitlist (WL) (n = 24). They completed four evaluations, at baseline (T1), after week 6 (T2), at post-treatment (T3), and at one month follow up (T4). Assessment measures were:1. Traumatic Events Screening Inventory (T1); 2. the Clinician Administered PTSD Scale (CAPS; T1, T3, T4); 3. the Davidson Trauma Scale (DTS; T1-T4) and 4. the Inventory of Altered Self-Capacities (IASC; T1-T4). NF training occurred two times per week for 12 weeks and involved a sequential placement with T4 as the active site, P4 as the reference site. Results Participants had experienced an average of 9.29 (SD = 2.90) different traumatic events. Post-treatment a significantly smaller proportion of NF (6/22, 27.3%) met criteria for PTSD than the WL condition (15/22, 68.2%), χ2 (n = 44, df = 1) = 7.38, p = .007. There was a significant treatment condition x time interaction (b = -10.45, t = -5.10, p< .001). Measures of tension reduction activities, affect dysregulation, and affect instability exhibited a significant Time x Condition interaction. The effect sizes of NF (d = -2.33 within, d = - 1.71 between groups) are comparable to those reported for the most effective evidence based treatments for PTSD. Discussion Compared with the control group NF produced significant PTSD symptom improvement in individuals with chronic PTSD, as well as in affect regulation capacities. NF deserves further investigation for its potential to ameliorate PTSD and to improve affect regulation, and to clarify its mechanisms of action. PMID:27992435

To investigate the effect of static magnetic field on deep wound healing of SD rats and VEGF during the wound healing and different strength static magnetic field on deep wound healing of SD rats. Divided forty-eight SD rats into three groups: 0.16 T magnetic disk treatment (0.16 T group), 0.32 T magnetic disk treatment (0.32 T group), control group. General wounds healing situation was observated on the 3, 6, 9, 12 day. The area of every wound was calculated. The tissue of granulation was dyeing by immune tissue chemical decoration method, in which VEGF protein content with its range in tissue was measured. The healing index of 0.16 T magnetic group wounds were larger than that of control group on 6th and 9th day, there were statistical difference. The healing index of 0.32 T magnetic group wounds were larger than that of control group on 3rd, 6th, 9th and 12th day, there were statistical difference. The healing index of 0.32 T group wounds contrasted to that of 0.16 T group wounds had no statistical significance. Observation of VEGF at the course of wound healing:the expressing of VEGF in magnetic group wounds on 3rd and 6th was stronger than in control group wounds, there were statistical difference. While there were no obvious difference between them on 9th and 12th day (P>0.05). But the contrast between that in 0.32 T group and in 0.16 T group had no statistical difference. The expressing strength of VEGF in magnetic group reached the peak amplitude on the 6th day, and that in control group reached peak amplitude on 9th day. And the peak amplitude of magnetic group was stronger than that of control group. Static magnetic disc of 0.16T and 0.32 T can promote deep wound of SD rats heal. The mechanism of static magnetic field promoting wound heal may be relative to the expressing highly of VEGF during early and middle time.

The purpose of this study was to determine the effects of obstructive sleep apnea syndrome (OSAS) on the submacular and peripapillary retinal nerve fiber layer (RNFL) and choroidal thickness (ChT). Eighty-four eyes of 42 male patients with OSAS and 112 eyes of 56 aged-matched and body mass index-matched healthy male subjects were enrolled in this case-control study. The ChT and peripapillary RNFL thickness was measured using enhanced depth imaging optical coherence tomography. The ChT and RNFL thickness measurements of the groups were compared, and correlations among the Apnea Hypopnea Index (AHI) values and these measurements were calculated. Right and left eyes were separately evaluated. There were no significant differences in the subfoveal and temporal ChT between the groups (p > 0.05). The OSAS group had significantly thicker ChT at 0.5 and 1.5 mm nasal to the fovea in both eyes than the control group (p < 0.05). The peripapillary ChT were significantly thicker in the OSAS group at all segments except for the temporal and superotemporal segments when compared with the control group (p < 0.05 for all quadrants except temporal and superotemporal). When compared with controls, the OSAS group had significantly thinner nasal RNFL thickness in the right eye (p = 0.01) and thinner mean RNFL thickness in both eyes (p < 0.001). Other RNFL thickness measurements were similar between groups (p > 0.05). Between AHI and mean RNFL thickness showed a median negative correlation (r = - 0.411, p = 0.001). The choroidal thickening in patients with OSAS may be associated with the pathophysiology of the neurodegeneration process of the disease.

In this sham-controlled study, 53 patients received 10 sessions of acupuncture treatment over 5 weeks to investigate the effects of acupuncture on the pain and quality of life of patients with osteoporosis. The results showed significant favorable effects of verum acupuncture on quality of life. Both interventions showed sustained and clinically relevant effects on pain. Standard analgesic treatment is associated with adverse events in patients with osteoporosis, especially elderly and/or comorbid patients. As acupuncture has gained widespread acceptance as a complementary treatment modality with few side effects, the aim of this study was to evaluate the effects of acupuncture on the pain and quality of life of patients with osteoporosis. In total, 53 patients with vertebral compression fractures, osteoporosis-associated spinal deformities, and resultant pain were randomly allocated to the verum acupuncture with deep needling of specific points following the principles of traditional Chinese medicine (n = 29) or control acupuncture group with superficial needling of non-acupuncture points (n = 24). All patients received 10 sessions of standardized verum or control acupuncture treatment over 5 weeks. Pain (VAS score 1-100) and quality of life (QUALEFFO-41) were measured at the start of treatment (T0), before each acupuncture session (T1), and at 1 (T2) and 3 months (T3) post-treatment. Both acupuncture treatments significantly reduced activity-related pain and pain at rest over time. The verum acupuncture group experienced a significantly greater reduction in mean pain intensity at rest than the control group. In the control group, quality of life improved only temporarily post-treatment (T2) and slightly declined at the end of the follow-up period (T3). In contrast, patients in the verum acupuncture group experienced continuous and significant improvements in quality of life up to 3 months after treatment (T3). Both types of acupuncture were equally effective in producing sustained, clinically relevant pain relief in patients with osteoporosis. Verum acupuncture had stronger and longer-lasting effects on quality of life and pain at rest. The possible reasons for these findings include the specificity of acupuncture point selection and the performance of needle stimulation.

The experiments were carried out to measure the effect of multivitamin, acidifier and Azolla on growth performance, profitability and lipid profiles of blood of broiler chickens to produce safe and cost effective broilers. In experiment 1, 240 day-old Cobb-500 broiler chicks were fed diets; D 1 (control), D 2 (D 1 with 1 mL multivitamin/liter water), D 3 (D 1 with 1 mL acidifier/liter water), D 4 (D 1 with 1 mL multivitamin and 2 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication. In experiment 2, 150 day-old Cobb-500 broiler chicks were fed diets; T 1 (control), T 2 (5% Azolla in the diet), T 3 (7% Azolla in the diet) and T 4 (T 1 with 1 mL multivitamin and 1 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication in control, and 10 chicks/replication in the remaining dietary treatment groups for 35 days. In experiment 1, the highest live weight was observed in D 4 (p<0.05), however, feed intake was statistically similar between diets (p>0.05). The lowest feed conversion ratio (FCR) (p<0.001) and mortality (p<0.05) were observed in D 2 followed by D 4 , D 1 , and D 3 , respectively. There were no significant differences between diets for feed cost and net profit (p>0.05). However, evidently but not significantly, the highest net profit was obtained in D 2 followed by D 4 , D 1 , and D 3 , respectively. In experiment 2, the highest live weight (p<0.05) and feed intake (p<0.001) were observed in T 4 . Mortality (p<0.01), FCR (p<0.01), feed cost (p<0.05) and net profit (p<0.05) were significantly different among diets. Considering net profit, T 2 was the best performing dietary group followed by T 3 , T 1 , and T 4 , respectively. The lowest lipid profiles were observed in D 3 followed by D 1 , D 4 , and D 2 , respectively (p<0.05). In experiment 2, the lowest total cholesterol, TG, and the highest amount of high density lipoprotein were observed in T 2 , followed by T 3 , T 1 , and T 4 , respectively (p<0.05). Evidently but not significantly, low density lipoprotein was the highest in T 2 followed by T 3 , T 4 , and T 1 , respectively (p>0.05). In conclusion, Azolla and acidifier reduced lipid profiles of broiler chickens. Considering net profit and lipid profiles, 5% Azolla may be the suitable dietary group for producing safe and profitable broilers. However, more studies are needed to confirm this study prior to suggesting using Azolla in the poultry industry.

We sought to determine the effect of group discussion-based education on the self-management capability of patients with type 2 diabetes in Iran. This randomized control trial was conducted on 90 patients with type 2 diabetes. Participants were allocated randomly into one of two groups; intervention and control. The intervention group received the group discussion-based education while the control group received routine care only. The Lin's self-management questionnaire was completed at baseline and three months post-intervention. Statistical analysis, including the use of independent t -test, identified that in comparison to the control group, significant increases were observed in the scores of self-organization ( t =11.24, p < 0.001), self-adjustment ( t = 7.53, p < 0.001), interaction with health experts ( t = 7.31, p < 0.001), blood sugar self-monitoring ( t = 6.42, p < 0.001), adherence to the proposed diet ( t = 5.22, p < 0.001), and total self-management ( t = 10.82, p < 0.001) in the intervention group. Sharing experiences through group discussions and receiving instructive feedback can improve the ability to self-manage diabetes.

Preterm infants are at risk for neurodevelopmental disorders, including motor, cognitive or behavioural problems, which may potentially be modified by early intervention. The EU CareToy Project Consortium (http://www.caretoy.eu) has developed a new modular system for intensive, individualized, home-based and family-centred early intervention, managed remotely by rehabilitation staff. A randomised controlled trial (RCT) has been designed to evaluate the efficacy of CareToy training in a first sample of low-risk preterm infants. The trial, randomised, multi-center, evaluator-blinded, parallel group controlled, is designed according to CONSORT Statement. Eligible subjects are infants born preterm without major complications, aged 3-9 months of corrected age with specific gross-motor abilities defined by Ages & Stages Questionnaire scores. Recruited infants, whose parents will sign a written informed consent for participation, will be randomized in CareToy training and control groups at baseline (T0). CareToy group will perform four weeks of personalized activities with the CareToy system, customized by the rehabilitation staff. The control group will continue standard care. Infant Motor Profile Scale is the primary outcome measure and a total sample size of 40 infants has been established. Bayley-Cognitive subscale, Alberta Infants Motor Scale and Teller Acuity Cards are secondary outcome measures. All measurements will be performed at T0 and at the end of training/control period (T1). For ethical reasons, after this first phase infants enrolled in the control group will perform the CareToy training, while the training group will continue standard care. At the end of open phase (T2) all infants will be assessed as at T1. Further assessment will be performed at 18 months corrected age (T3) to evaluate the long-term effects on neurodevelopmental outcome. Caregivers and rehabilitation staff will not be blinded whereas all the clinical assessments will be performed, videotaped and scored by blind assessors. The trial is ongoing and it is expected to be completed by April 2015. This paper describes RCT methodology to evaluate CareToy as a new tool for early intervention in preterm infants, first contribution to test this new type of system. It presents background, hypotheses, outcome measures and trial methodology. ClinicalTrials.gov: NCT01990183. EU grant ICT-2011.5.1-287932.

This study aimed to examine the associations between intakes of various nutrients and food groups and colorectal cancer risk in a case-control study among Koreans aged 20 to 80 years. A total of 150 new cases and 116 controls were recruited with subjects' informed consent. Dietary data were collected using the food frequency questionnaire developed and validated by the Korea Centers for Disease Control and Prevention. Multivariate logistic regression models were used to estimate odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for colorectal cancer incidence. High intakes of total lipid (ORT3 vs T1 = 4.15, 95% CI: 1.33-12.96, p for trend = 0.034), saturated fatty acid (ORT3 vs T1 = 2.96, 95% CI: 1.24-7.04, p for trend = 0.016) and monounsaturated fatty acid (ORT3 vs T1 = 3.04, 95% CI: 1.23-7.54, p for trend = 0.018) were significantly associated with increased incidence of colorectal cancer. High dietary fiber (ORT3 vs T1 = 0.22, 95% CI: 0.08-0.56, p for trend = 0.002) and vitamin C (ORT3 vs T1 = 0.38, 95% CI: 0.14-1.05, p for trend = 0.021) intakes were significantly associated with reduced colorectal cancer incidence. From the food group analysis, bread (ORT3 vs T1 = 2.26, 95% CI: 0.96-5.33, p for trend = 0.031), red meat (ORT3 vs T1 = 7.33, 95% CI: 2.98-18.06, p for trend < 0.001), milk·dairy product (ORT3 vs T1 = 2.42, 95% CI: 1.10-5.31, p for trend = 0.071) and beverage (ORT3 vs T1 = 3.17, 95% CI: 1.35-7.48, p for trend = 0.002) intakes were positively associated with colorectal cancer risk. On the other hand, high intake of traditional rice cake (ORT3 vs T1 = 0.35, 95% CI: 0.14-0.86, p for trend = 0.024) was linked with lower colorectal cancer incidence. In conclusion, eating a diet high in total lipid, saturated fatty acids and monounsaturated fatty acids is associated with higher incidence of colorectal cancer, whereas a diet high in dietary fiber and vitamin C was found to lower the incidence in Korean adults. Interestingly high traditional rice cake consumption is associated inversely with colorectal cancer incidence, warranting a future study. PMID:25954732

Type 1 narcolepsy (NT1) is a central hypersomnia linked to the destruction of hypocretin-producing neurons. A great body of genetic and epidemiological data points to likely autoimmune disease aetiology. Recent reports have characterized peripheral blood T-cell subsets in NT1, whereas data regarding the cerebrospinal fluid (CSF) immune cell composition are lacking. The current study aimed to characterize the T-cell and natural killer (NK) cell subsets in NT1 patients with long disease course. Immune cell subsets from CSF and peripheral blood mononuclear cell (PBMC) samples were analysed by flow cytometry in two age-balanced and sex-balanced groups of 14 NT1 patients versus 14 healthy controls. The frequency of CSF cell groups was compared with PBMCs. Non-parametric tests were used for statistical analyses. The NT1 patients did not show significant differences of CSF immune cell subsets compared to controls, despite a trend towards higher CD4 + terminally differentiated effector memory T cells. T cells preferentially displayed a memory phenotype in the CSF compared to PBMCs. Furthermore, a reduced frequency of CD4 + terminally differentiated effector memory T cells and an increased frequency of NK CD56 bright cells was observed in PBMCs from patients compared to controls. Finally, the ratio between CSF and peripheral CD4 + terminally differentiated effector memory T cells was two-fold increased in NT1 patients versus controls. Significant differences in PBMCs and in CSF/PBMC ratios of immune cell profile were found in NT1 patients compared to healthy controls. These differences might have arisen from the different HLA status, or be primary or secondary to hypocretin deficiency. Further functional studies in patients close to disease onset are required to understand NT1 pathophysiology. Copyright © 2017 Elsevier B.V. All rights reserved.

Despite major advances, the treatment of sepsis is still a challenging problem for surgeons. This study was aimed to compare the therapeutic effects of methylprednisolone and tri-iodothyronine replacement therapy during an early sepsis. Forty male Wistar albino rats weighing 300-340 g were divided into the Control, CLP, CLP/MP, CLP/T3 and CLP/MP/T3 groups. The Control group underwent a sham operation. Only cecal ligation and puncture was performed in the CLP group. The CLP/MP groups received an intramuscular injection of (MP) methylprednisolone (30 mg/kg) at one and half hour before CLP. The CLP/T3 group was given an intraperitoneal (IP) injection of tyroid hormone (T3) 0.4 µg/100 g immediately after CLP. The CLP/MP/T3 group was given IM injection of MP 30 mg/kg before CLP and IP injection of T3 0.4 µg/100 g after CLP. Hemavet changes, blood cultures, peritoneal bacteria content, hormonal alterations and histopathologic changes of intestinal, lung and liver tissue were used to asses the possible therapeutic effects of MP and T3 during early sepsis. A septic insult resulted in significant alterations on hemavet values, free T3, free T4 and cortisol levels, peritoneal bacteria content and intestinal lung and liver tissue samples of the CLP group. Hemavet changes and peritoneal inflammation findings were significantly limited in the CLP/T3 and CLP/MP/T3 groups. Histopathologic changes had no significant difference between the groups during an early sepsis. Compared to the MP replacement therapy, therapeutic effects of T3 replacement therapy have been found significantly more promising (Tab. 1, Fig. 10, Ref. 49).

The pathogenesis of aspirin-exacerbated respiratory disease (AERD) is thought to be based on, mainly, overproduction of eicosanoid lipid mediators and on defective anti-inflammatory regulators. Aspirin desensitization treatment, the mainstay of controlling asthma and rhinitis in AERD patients, however, is the least understood aspect of the disease. The study was designed to determine the effect of aspirin desensitization on T-lymphocyte cytokine expression and on plasma lipoxin levels in AERD. Spirometry, skin-prick test and asthma control test were documented and intracellular cytokine expression in T lymphocytes and plasma lipoxin levels were measured in 23 AERD patients, 17 aspirin-tolerant asthmatic (ATA) patients, and 16 healthy controls. In the AERD group nasal symptom and smell scores were assessed. Of the 23 AERD patients 15 accepted to undergo aspirin desensitization protocol and 14 of them were desensitized successfully. In the desensitized AERD group, cytokine and lipoxin measurements were repeated after 1-month aspirin treatment. CD4(+) IL-10 levels were higher in AERD patients than in healthy controls and CD4(+) interferon (IFN) gamma levels were higher in AERD and ATA patients than in controls. Plasma lipoxin-A4 and 15-epi-lipoxin-A4 levels were similar among the three study groups. In the AERD group, subjects underwent aspirin desensitization followed by a 1-month aspirin treatment. Clinical parameters improved and CD4(+) IFN-gamma levels decreased significantly. No significant change in lipoxin levels was recorded. CD4(+) IFN-gamma and CD4(+) IL-10 levels in AERD patients after 1-month aspirin desensitization treatment were similar to the healthy controls. The study confirms aspirin desensitization is effective clinically in AERD patients and suggests that IFN gamma and IL-10 expression in CD4(+) T lymphocytes may be related to the mechanism of action.

Alzheimer disease (AD) brain is characterized by extracellular plaques of amyloid β (Aβ) peptide with reactive microglia. This study aimed to determine whether a dietary intervention could attenuate microgliosis. Memory was assessed in 12-mo-old male amyloid precursor protein/presenilin 1 (APP/PS1) transgenic mice via Barnes maze testing followed by division into either a control-fed group provided free access to normal chow and water or a treatment group provided free access to normal chow and drinking water supplemented with pomegranate extract (6.25 mL/L) for 3 mo followed by repeat Barnes maze testing for both groups. Three months of pomegranate feeding decreased the path length to escape of mice compared with their initial 12-mo values (P < 0.05) and their control-fed counterparts (P < 0.05). Brains of the 3-mo study pomegranate-fed mice had lower tumor necrosis factor α (TNF-α) concentrations (P < 0.05) and lower nuclear factor of activated T-cell (NFAT) transcriptional activity (P < 0.05) compared with controls. Brains of the 3-mo pomegranate or control mice were also compared with an additional control group of 12-mo-old mice for histologic analysis. Immunocytochemistry showed that pomegranate- but not control-fed mice had attenuated microgliosis (P < 0.05) and Aβ plaque deposition (P < 0.05) compared with 12-mo-old mice. An additional behavioral study again used 12-mo-old male APP/PS1 mice tested by T-maze followed by division into a control group provided with free access to normal chow and sugar supplemented drinking water or a treatment group provided with normal chow and pomegranate extract-supplemented drinking water (6.25 mL/L) for 1 mo followed by repeat T-maze testing in both groups. One month of pomegranate feeding increased spontaneous alternations versus control-fed mice (P < 0.05). Cell culture experiments verified that 2 polyphenol components of pomegranate extract, punicalagin and ellagic acid, attenuated NFAT activity in a reporter cell line (P < 0.05) and decreased Aβ-stimulated TNF-α secretion by murine microglia (P < 0.05). These data indicate that dietary pomegranate produces brain antiinflammatory effects that may attenuate AD progression.

The present study aims to investigate the effects of both garlic and curcumin through evaluating their therapeutic properties as antioxidants on liver and kidney functions, hepatic antioxidants and GPx gene expression against aflatoxicosis of O. niloticus. In total, 180 of tilapia were divided into ten groups; T1 represented the negative control fed on a basal diet, and T2 was injected with a single intraperitoneal (i.p.) dose of AFB1 (6 mg/kg b.w.). Fish in T3-T6 were fed on a basal diet supplemented with both garlic (T3 and T4) and curcumin (T5 and T6) at the two concentrations of 10 and 20 g/kg diet, respectively. Fish in T7-T10 groups were injected with AFB1 and fed on the garlic (T7 and T8) and curcumin (T9 and T10) dietaries. The results showed that AFB1 has significant potency for increasing the activity of plasma AST, ALT, creatinine and uric acid values, and hepatic MDA as well as for reducing the concentrations of plasma TP, AL, GL and hepatic activity of TAC, while AFB1 led to up-regulated GPx gene expression when compared to the control (T1). These harmful effects of AFB1 were alleviated due to the garlic and curcumin dietaries in some studied parameters. Garlic reflected the highest induction of gene expression (T7); however, curcumin showed significant down-regulated (T9). These results concluded that the effects of garlic were better than curcumin at the two concentrations and the low concentration of them is more beneficial than the high concentration when it used against AFB1 in O. niloticus.

Oxidative stress is a well known phenomenon under hyperthyroid condition that induces various physiological and neural problems with a higher prevalence in females. We, therefore investigated the antioxidant potential of melatonin (Mel) on hyperthyroidism-induced oxidative stress and neuronal cell death in the hippocampus region of brain (cognition and memory centre) of aged female golden hamster, Mesocricetus auratus. Aged female hamsters were randomly divided into four experimental groups (n=7); group-I: control, group-II: Melatonin (5mgkg(-1)day(-1), i.p., for one week), group-III: Hyperthyroid (100μg kg(-1)day(-1), i.p., for two weeks) and group-IV- Hyper+Mel. Hormonal profiles (thyroid and melatonin), activity of antioxidant enzymes (SOD, CAT and GPX), lipid peroxidation level (TBARS) and the specific apoptotic markers (Bax/Bcl-2 ratio and Caspase-3) expression were evaluated. A significant increase in the profile of total thyroid hormone (tT3 and tT4) in hyperthyroidic group as compared to control while tT3 significantly decreased in melatonin treated hyperthyroidic group. However, Mel level significantly decreased in hyperthyroidic group but increased in melatonin treated hyperthyroidic group. Further, the number of immune-positive cells for thyroid hormone receptor-alpha (TR-α) decreased in the hippocampus of hyperthyroidic group and increased in melatonin treated hyperthyroidic group. Profiles of antioxidant enzymes showed a significant decrease in hyperthyroidic group with a simultaneous increase in lipid peroxidation (TBARS). Melatonin treatment to hyperthyroidic group lead to decreased TBARS level with a concomitant increase in antioxidant enzyme activity. Moreover, increased expression of Bax/Bcl-2 ratio and Caspase-3, in hyperthyroidic group had elevated neuronal cell death in hippocampal area and melatonin treatment reduced its expression in hyperthyroidic group. Our findings thus indicate that melatonin reduced the hyperthyroidism-induced oxidative stress and neuronal cell death in the hippocampus region of brain, suggesting a novel therapeutic approach of melatonin for management of cognition and memory function in females under hyperthyroid condition.

Several types of receptors are found at neuromuscular presynaptic membranes. Presynaptic inhibitory A1 and facilitatory A2A receptors mediate different modulatory functions on acetylcholine release. This study investigated whether adenosine A1 receptor agonist contributes to the first twitch tension (T1) of train-of-four (TOF) stimulation depression and TOF fade during rocuronium-induced neuromuscular blockade, and sugammadex-induced recovery. Phrenic nerve-diaphragm tissues were obtained from 30 adult Sprague-Dawley rats. Each tissue specimen was randomly allocated to either control group or 2-chloroadenosine (CADO, 10 μM) group. One hour of reaction time was allowed before initiating main experimental data collection. Loading and boost doses of rocuronium were sequentially administered until > 95% depression of the T1 was achieved. After confirming that there was no T1 twitch tension response, 15 min of resting time was allowed, after which sugammadex was administered. Recovery profiles (T1, TOF ratio [TOFR], and recovery index) were collected for 1 h and compared between groups. There were statistically significant differences on amount of rocuronium (actually used during experiment), TOFR changes during concentration-response of rocuronium (P = 0.04), and recovery profiles (P < 0.01) of CADO group comparing with the control group. However, at the initial phase of this experiment, dose-response of rocuronium in each group demonstrated no statistically significant differences (P = 0.12). The adenosine A1 receptor agonist (CADO) influenced the TOFR and the recovery profile. After activating adenosine receptor, sugammadex-induced recovery from rocuronium-induced neuromuscular block was delayed.

The aim of this study was to evaluate: (1) the cardiovascular parameters and plasma biomarkers in people with type 1 diabetes mellitus (T1DM) at baseline; and (2) the heart rate variability (HRV) and blood glucose in response to a session of aerobic exercise (AE) and during recovery period. Adults (18-35 years) were divided into two groups: control (CT, n=10) and T1DM (n=9). Anthropometric, cardiovascular, and biochemical parameters, and aerobic capacity (indirect peak oxygen uptake, VO2peak) were evaluated at baseline. Thirty minutes of AE (40-60% intensity) was performed on a treadmill. Blood glucose and HRV were determined at rest, during AE, and during the recovery period. Anthropometric measurements, cardiovascular parameters, aerobic capacity, and biochemical parameters were similar between the groups at baseline. In the T1DM group, blood glucose, glycated hemoglobin, and thiobarbituric acid reactive substances concentrations were increased while nitrite/nitrate (NOx(-)) levels were reduced. During AE, the magnitude of the reduction of blood glucose was greater than that during the recovery period in the T1DM group. The RR intervals and SDNN were reduced at rest as well as in the recovery period in T1DM subjects, whereas the RMSSD and pNN50 were only reduced during the recovery period. No changes were observed in low frequency (LF), high frequency (HF), and LF/HF ratio. Our study shows that T1DM patients on insulin therapy have poor blood glucose control with greater lipid peroxidation and lower NOx(-) levels, accompanied by an imbalance in autonomic function detected by the challenge of AE.

To investigate the preventive effect of magnesium isoglycyrrhizinate against acute drug-induced liver damage from initial chemotherapy treatment in patients with gastrointestinal cancer. A total of 216 cases with early stage gastric cancer and indications for systemic chemotherapy that had been diagnosed with gastrointestinal malignant tumors by pathology in our hospital were enrolled for study during the period of January 2011 to June 2013.Using a prospective randomized controlled study design,differences were assessed between groups treated with glycyrrhizic acid magnesium (experimental group; n=114) or glutathione (control group; n=102) and the FOLFOX regimen (n=104) or the XELOX regimen (n=112).Patients in the FOLFOX group received intravenous infusion of L-OHP (85 mg/m²) at day 1,followed by a bolus injection of 5-FU (400 mg/m²) at days 1-2 and continuous intravenous infusion of 5-FU (600 mg/m²) for 22 h at days 1-2,with one cycle comprising 2 weeks. Patients in the XELOX group received intravenous infusion of L-OHP (130 mg/m²) at day 1, followed by capecitabine (1 000 mg/m²) oral twice a day at days 1-14,with one cycle comprising 3 weeks.In the first cycle of chemotherapy,serum was extracted from the patients at 1 day before chemotherapy and 1 week after chemotherapy.An automated biochemistry analyzer was used to measure alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) and alkaline phosphatase (ALP). Differences between groups were statistically analyzed by the t-test and x² test. Among the total 216 cases treated with chemotherapy,40 showed hepatic biochemical abnormalities (12 cases in the experimental group, 28 cases in the control group), and the effect of prevention was significantly different between the two groups (10.53% vs. 27.25%; x² =10.219, P less than 0.005).The acute and subacute hepatic toxicity reaction degrees for the experimental and the control groups were: 0:94.78% vs. 88.2%; 1:5.3% vs. 11.8% (x² =6.99, P < 0.01). One week after chemotherapy, the liver biochemical indexes in the experimental group (ALT:35.93 ± 8.33 U/L; AST:24.84 ±2.91 U/L; TBil:13.29 ± 5.89 mumol/L; ALP:125.1 ± 53.61 U/L) were statically different from those in the control group (all P < 0.05). The liver biochemical indexes before and after chemotherapy were also significantly different between the experimental group (ALT:13.18t3.23 U/L; AST:5.39 ± 2.57 U/L; TBil:2.79 ± 0.23 mumol/L; ALP:52.08 ± 4.83 U/L) and the control group (all P < 0.05).One week after chemotherapy in the experimental group, the groups treated with the FOLFOX regimen or the XELOX regimen showed no statistical differences in the liver biochemical indexes.One week after chemotherapy in the control group, though, the groups treated with the FOLFOX regimen showed significantly lower AST (26.24 ± 3.50 U/L vs. 29.80 ± 6.57 U/L, t=-2.431, P < 0.05),but the residual liver biochemical indexes were not significantly different.In the experimental group, the FOLFOX group showed significantly lower ALP (53.44 ± 2.47 U/L vs. 56.58 ± 6.70 U/L, t =-2.201, P < 0.05), AST (6.48 ± 3.15U/L vs. 9.88 ± 4.57 U/L, t =-5.223, P < 0.05), but the residual liver biochemical index was not significantly different. Magnesium isoglycyrrhizinate is an effective drug for the prevention of drug-induced liver damage after initial chemotherapy in patients with early stage gastrointestinal cancer.

Young adults with type 1 diabetes (T1D) experience poor glycemic control, disengagement in care, and are often lost to the medical system well into their adult years. Diabetes providers need a new approach to working with the population. The goal of this study was to determine whether an innovative shared telemedicine appointment care model (CoYoT1 Clinic [pronounced as "coyote"; Colorado Young Adults with T1D]) for young adults with T1D improves care engagement, satisfaction, and adherence to American Diabetes Association (ADA) guidelines regarding appointment frequency. CoYoT1 Clinic was designed to meet the diabetes care needs of young adults (18-25 years of age) with T1D through home telemedicine. Visits occurred every 3 months over the 1-year study (three times by home telemedicine and one time in-person). Outcomes were compared to patients receiving treatment as usual (control). Compared with controls, CoYoT1 patients attended significantly more clinic visits (P < 0.0001) and increased their number of clinic visits from the year before the intervention. Seventy-four percent of CoYoT1 patients were seen four times over the 12-month study period, meeting ADA guidelines, but none in the control group met the ADA recommendation. CoYoT1 patients used diabetes technologies more frequently and reported greater satisfaction with care compared with controls. Delivering diabetes care by home telemedicine increases young adults' adherence to ADA guidelines and usage of diabetes technologies, and improves retention in care when compared to controls. Home telemedicine may keep young adults engaged in their diabetes care during this challenging transition period.

To explore the role of Pim-1 in the pathology of inflammatory bowel disease and the potential effect of Pim-1 inhibitor on treating such disease.
 Methods: Forty-five BALB/c mice were randomly divided into 5 groups (n=9): A normal control group, a inflammatory bowel disease group, two different dose of Pim-1 inhibitor treatment groups, and steroidhormone treatment group. The model of inflammatory bowel disease was induced by intracolonic administration of 2, 4, 6-trinitrobenzenestdfonic acid (TNBS) and ethanol mixture. Mice were treated with Pim-1 inhibitor [intraperitoneal inject, 5 or 10 mg/(kg.d)] for 5 days and prednisone (intragastric administration, 0.1 mg/d) for 5 days. The DAI, colon length, gross score and pathological grade were evaluated. The expressions of T cell master transcription factors T-box expressed in T cells (T-bet), GATA binding protein 3 (GATA-3), RA orphan receptorγ (RORγt) and forkhead box P3 (Foxp3) were measured by Real-time PCR and Western blot, respectively.
 Results: Pim-1 inhibitor and prednisone showed therapeutic effect on acute TNBS colitis in vivo. GATA3 and RORγt were significantly up-regulated in acute TNBS colitis (P<0.05). In contrast, the expression of Foxp3 was suppressed in the inflammatory bowel disease group, whereas it did not cause any significant change in T-bet expression (P>0.05). Administration of Pim-1 inhibitor and prednisone resulted in suppression of GATA3, RORγt expression, and the increase of Foxp3 expression (P<0.05). Administration of Pim-1 inhibitor and prednisone resulted in inhibition of T-bet mRNA expression (P<0.05), but only prednisone could inhibit T-bet protein expression (P>0.05).
 Conclusion: Pim-1 inhibitor significantly suppresses Th2- and Th17-type immune responses. Furthermore, Pim-1 inhibitor could induce T-cell differentiation towards a Treg phenotype. Pim-1 inhibitor has therapeutic effect on acute TNBS colitis.

Low fat pork sausages were formulated with tomato powder at 0% (C), 0.8% (T1), 1.2% (T2) and 1.5% (T3) levels in basic formula. With the increase in tomato powder concentration the lightness of the sausage decreased but the redness and yellowness increased significantly (p < 0.05). The pH values of T2 and T3 were significantly (p < 0.05) lower than the others, whereas, water holding capacity of T2 and T3 was significantly (p < 0.05) higher. Thiobarbituric acid reactive substances, cohesiveness and springiness values of treated groups were significantly (p < 0.05) lower than those of control samples, however, hardness values of sausages with tomato powder were significantly (p < 0.05) higher. The scores of overall acceptability in tested groups were significantly (p < 0.05) higher than those of control samples after 30 days of storage. The low fat pork sausage with tomato powder up to 1.5% was found to be well acceptable up to 30 days at refrigerated storage. This new product will have special value due to the functional additive lycopene in tomato powder.

This quasi-experimental longitudinal study documented the impact of a comprehensive cancer informational intervention using information technology on healthcare service use among individuals newly diagnosed with cancer. Women with breast cancer (n = 205) and men with prostate cancer (n = 45) were recruited within 8 weeks of diagnosis at 4 university teaching hospitals in Montreal, Quebec, Canada. The intervention group (n = 148) received a 1-hour training on information technology use, a CD-ROM on cancer, and a list of reputable cancer-related Web sites. The intervention material was available for a period of 8 weeks. The control group (n = 102) received usual care. Self-reported questionnaires were completed at T1 (baseline), T2 (1 week after intervention), and T3 (3 months after intervention). Using multivariate statistics, the experimental group reported significantly more satisfaction with cancer information received compared to the control group. No significant differences were found between experimental and control groups in their reliance on healthcare services. However, women as opposed to men spent more time with nurses, were more satisfied with cancer information received, and relied more heavily on health services. Future research would explore whether the latter observations reflect genuine sex differences or are more contingent on the specific cancer diagnosis.

To assess Factor V Leiden (FVL) (rs6025), Prothrombin G20210A (rs1799963), MTHFR C677T (rs1801133), and MTHFR A1298C (rs1801131) gene mutations as risk factors in the development of retinopathy of prematurity (ROP). A total of 105 children were included in this cross-sectional study. Patients were divided into two groups. The study group consisted of 55 infants with a history of ROP and the control group comprised 50 healthy infants with term birth. All subjects were screened for the presence of certain mutations (FVL, Prothrombin G20210A, MTHFR C677T and MTHFR A1298C) by Real-Time PCR at 1 year of age. The mean gestational age (GA) and birth weight (BW) of the study group were, 28.65 ± 2.85 weeks and 1171 ± 385.74 g, respectively. There were no significant differences of genotype and allele frequency of Prothrombin G20210A, MTHFR A1298C and MTHFR C677T between the study and control groups (p > 0.05). Eight children (14.5 %) had heterozygous and one child (1.8%) had homozygous FVL mutation in the study group. One child (2%) in the control group had heterozygous FVL mutation. There was statistically significant differences of FVL allele and genotype frequencies between the groups (p < 0.05). The prevalence of FVL polymorphism (16.3 %) was higher in ROP patients than control subjects in this Turkish cohort. We suggest a possible association of FVL mutation with ROP at the end of the study.

To evaluate the changes of CD(4)(+) IL-17+T (Th17) and CD(4)(+)Foxp3+regulatory T (Treg) cells in peripheral blood and bronchoalveolar lavage fluid (BALF) , and therefore to explore the role of Th17 and Treg in acrolein exposure airway inflammation in rats. Forty male Wistar rats were randomly divided into 4 groups: a 2 wk acrolein exposure group, a 4 wk acrolein exposure group, a 2 wk control group and a 4 wk control group (n=10 each). Cells in BALF were collected and analyzed by absolute and differential cell counts.IL-17 and IL-6 levels in serum and BALF were tested by enzyme linked immunosorbent assay (ELISA). The proportion of CD(4)(+)IL-17+T and CD(4)(+) Foxp3+Treg in peripheral blood and BALF were determined by flow cytometry.The mRNA expressions of IL-17 and Foxp3 were measured by real-time PCR. Comparisons of the data between different groups were performed using one-way ANOVA, and SNK and Games-Howell test were used for comparison between 2 groups. Levels of IL-17 were remarkable increased in the 2 wk acrolein exposure group and the 4 wk acrolein exposure group in serum [(52.64 ± 1.89) ng/L, (76.73 ± 5.57) ng/L], and BALF [(79.07 ± 5.67) ng/L, (96.61 ± 6.44) ng/L] compared with the 2 wk control group [(40.05 ± 3.12) ng/L, (56.75 ± 4.37) ng/L] and the 4 wk control group [(38.75 ± 3.23) ng/L, (53.27 ± 4.48) ng/L], all P<0.01. IL-6 was increased in the 2 wk and the 4 wk acrolein exposure group [ (33.28 ± 2.27) ng/L, (46.24 ± 3.16) ng/L] compared with the 2 wk and the 4 wk control group [ (16.37 ± 1.49) ng/L, (17.02 ± 1.43) ng/L] in BALF.Ratio of Th17 was higher in the 2 wk and the 4 wk acrolein exposure groups in peripheral blood (1.82 ± 0.18) %, (3.75 ± 0.48) % and BALF [(7.23 ± 0.27) %, (8.12 ± 0.38) %] compared with the 2 wk [(0.96 ± 0.07) %, (5.64 ± 0.63) %] and the 4 wk control group [(1.01 ± 0.08) %, (5.86 ± 0.57) %]. Ratio of Treg in BALF was higher in the acrolein exposure groups [ (8.83 ± 0.52) %, (12.05 ± 0.74) %] compared with the control groups [(4.37 ± 0.27) %, (5.01 ± 0.37) %]. The level of IL-17 mRNA was increased in the 2 wk and the 4 wk acrolein exposure group in peripheral blood [(25.78 ± 2.31), (34.69 ± 2.01) ] and in BALF [(23.04 ± 1.78), (34.56 ± 3.12)] compared with the 2 wk [(11.04 ± 2.53), (11.08 ± 2.05)] and the 4 wk [(12.03 ± 2.34), (12.69 ± 2.69)] control groups. Foxp3 mRNA was increased in the acrolein exposure groups [ (26.37 ± 3.24), (33.19 ± 2.98)] (24.4 ± 2.7), (30.3 ± 2.7) compared with the control groups [(12.37 ± 2.56), (13.12 ± 3.08)]. Th17 in acrolein exposure groups was positively correlated with counts of total cells and macrophages (r=0.5126, 0.5437, all P<0.01). A changed expression of Th17 and Treg cells and an vary of inflammatory cytokines were evident in airway inflammation of acrolein exposed rats, suggesting that Treg was involved in the immunological regulation and Th17 was associated with the persistent inflammation in acrolein induced airway inflammation in rats.

Concerns about patient safety and reducing harm have led to a particular focus on initiatives that improve healthcare quality. However Quality Improvement (QI) initiatives have in the past typically faltered because they fail to fully engage healthcare professionals, resulting in apathy and resistance amongst this group of key stakeholders. Productive Ward: Releasing Time to Care (PW) is a ward-based QI programme created to help ward-based teams redesign and streamline the way that they work; leaving more time to care for patients. PW is designed to engage and empower ward-based teams to improve the safety, quality and delivery of care. The main objective of this study was to explore whether PW sustains the 'engagement' of ward-based teams by examining the longitudinal effect that the national QI programme had on the 'work-engagement' of ward-based teams in Ireland. Utilising the Utrecht Work Engagement Scale questionnaire (UWES-17), we surveyed nine PW (intervention) sites from typical acute Medical/Surgical, Rehabilitation and Elderly services (representing the entire cohort of a national phase of PW implementation in Ireland) and a cohort of matched control sites. The numbers surveyed from the PW group at T1 (up to 3 months after commencing the programme) totalled 253 ward-team members and 249 from the control group. At T2 (12 months later), the survey was repeated with 233 ward-team members from the PW sites and 236 from the control group. Overall findings demonstrated that those involved in the QI initiative had higher 'engagement' scores at T1 and T2 in comparison to the control group. Total 'engagement' score (TES), and its 3 dimensions, were all significantly higher in the PW group at T1, but only the Vigour dimension remained significantly higher at T2 (p = 0.006). Our results lend some support to the assertions of the PW initiative itself and suggest that when compared to a control group, ward-based teams involved in the QI programme are more likely to be 'engaged' by it and its associated improvement activities and that this is maintained over time. However, only the Vigour dimension of 'engagement' remained significantly higher in the PW over time.

The quality of glycaemic control of patients with T1D and T2D can be assessed with HbA (1c) levels. We aimed to assess the quality of glycaemic control and the prevalence of inadequately controlled diabetes in German primary care, and to determine simple patient and treatment related factors associated with poor control. Using a nationwide probability sample of 3 188 general practices (response rate 50.6%), a total of 55,518 patients were assessed in DETECT, a cross-sectional and prospective multistage epidemiological study. Diabetes diagnoses were based on physician assessment. HbA (1c) values were taken from the patient charts. The quality of metabolic control was unsatisfactory on the whole in the 277 people with T1D (e.g. mean HbA (1c)=7.4%+/-1.4%). The 8 188 people with T2D had a mean HbA (1c) of 6.89%+/-1.2%. 38.8% of individuals had an HbA (1c)>/=7.0%. The situation was less favourable in subjects with a longer history of diabetes - in many cases in those with diabetes for 5-9 years, but generally in those with a plus-10-year history of diabetes - and also in younger men with a shorter disease history. Patients with a short T2D history, especially older subjects had more favourable values. With regard to age, a higher percentage of patients had an HbA (1c)>/=7.0% (42.0% and 40.6%) in the 45-54 and 55-64 year olds. With respect to the correlation between HbA (1c) and treatment modality, we identified the best metabolic control in T2D patients without drug therapy for diabetes, and the worst in patients on combination regimens (OAD/insulin). The average duration of diabetes in the various treatment groups differs substantially. The average duration was highest (12.1 y) in the insulin group. Oral treatment was the predominant treatment modality in all HbA (1c) categories. T1D treatment needs to be improved overall. The situation as regards T2D is less clear-cut. When people with T2D start requiring more intensive and complex treatment in response to disease progression, the treatment efforts of patients and physicians evidently fail to keep up with the actual pace of metabolic deterioration. Early and strict alignment with approximately normal HbA (1c) targets is essential. Close attention should be paid to T2 diabetics with a 5-9-year diabetes history, with the aim of preventing any loss of metabolic control. Likewise, patients aged 45-64 y and younger men require more attention.

Objectives: To generate an orthotopic left lung transplantation model in mice, and to observe the early changes of respiratory system resistance and γδT lymphocytes infiltrated in grafts. Methods: The research time was from March 2014 to May 2015. The male C57BL/6 mice ( n =35) and BALB/c mice (syngenic group, n =10) were randomly divided into five groups. Control group ( n =5): wild C57BL/6 mice; syngenic transplant group ( n =10): C57BL/6→C57BL/6; allogenic transplant group(allogenic group, n =10): BALB/c→C57BL/6; each transplant group was randomly divided into 3-day and 7-day subgroups ( n =5). Respiratory system resistance and histological features of grafts were assessed, and differences in graft infiltrating γδT lymphocytes and mRNA expression of interleukin (IL)-17A were quantified on 3 and 7 days after transplantation. Multiple comparisons were performed using one-way analysis of variance and least significant difference analysis. Results: (1) The respiratory system resistance of syngenic group and allogenic group were (2.61±0.59) cmH 2 O·s/ml and (2.84±0.31) cmH 2 O·s/ml 3 days post-operation, both of them increased compared to control group (1.39±0.17) cmH 2 O·s/ml (1 cmH 2 O=0.098 kPa) ( P =0.001, 0.000). The respiratory system resistance of allogenic group were (4.33±0.67) cmH 2 O·s/ml 7 days post-operation, which was significantly higher than that of syngenic 7-day subgroup (1.87±0.27) cmH 2 O·s/ml and control group (1.39±0.17) cmH 2 O·s/ml ( P =0.000, 0.000). (2) The isografts of syngenic group showed a relatively normal histological appearance with minimal infiltration of inflammatory cells, and the allografts of allogenic group infiltrated apparently by inflammatory cells, especially 7-day subgroup showed acute cellular rejection. (3) The percentage of γδT lymphocytes infiltrated in isografts and allografts were 3.90%±0.86% and 4.40%±0.57%, respectively, which were significantly increased compared to that of control lungs 2.00%±0.23% 3 days post-operation( P =0.000, 0.000); The percentage of γδT lymphocytes infiltrated in 7 days allografts was 5.40%±0.98% , which was higher compared to that of 7 days isografts 2.60%±0.54% and control lungs 2.00%±0.23% ( P =0.000, 0.000). (4) IL-17A mRNA expression levels were 3.37±0.55 and 5.23±1.50 in isografts and 6.77±0.93 and 27.32±4.20 in allografts, on postoperative day 3 and 7 respectively. All of them were significantly upregulated compared to that of control lungs 0.99±0.08 ( P =0.000, 0.000), and allografts exhibited significantly greater IL-17A transcript levels compared to isografts on postoperative day 3 and 7 ( P =0.000, 0.000). Conclusion: The rise of respiratory system resistance of lung grafts after transplantation may relate to the increased IL-17A-producing γδT lymphocytes infiltrated in the grafts.

Thirty-six, twenty-eight-day-old broiler chicks were randomly distributed into three groups of 12 birds each. Two groups were fed diets containing 10 ppm cyclopiazonic acid (CPA) and 1ppm T-2 toxin, respectively, to determine the mechanism of cell death in spleen and thymus at 6, 12, 24, and 36 h of post-treatment. The other group served as control. T-2 toxin treated group showed significant (P < 0.01) induction of apoptosis in thymus with peak induction at 24 h post-treatment where as, no significant differences were observed between the control and CPA groups. The CPA toxin treated group showed significant (P < 0.01) induction of apoptosis in spleen with peak induction at 24 h post-treatment. No significant differences were observed between the control and T-2 toxin group even though the latter showed a slight increase in the quantity of apoptotic cells at 36 h post-treatment in spleen. The semi-thin sections stained with toluidine blue from the spleen of CPA treated group exhibited crescent margination of chromatin against the nuclear envelope and shrinkage of lymphoid cells without any surrounding inflammation, the characteristics of apoptosis. The apoptotic thymocytes from T-2 fed birds appeared shrunken with condensed nucleus and showed crescent margination of chromatin against the nuclear envelope without any surrounding inflammation when compared with well-defined nuclei with dispersed chromatin in normal thymocytes. Ultrastructurally, splenocytes of the CPA treated group and thymocytes of the T-2 toxin treated birds showed apoptotic bodies characterized by crescent margination of the chromatin against the nuclear envelope. The study indicates that one route of the CPA and T-2 toxin induced cell death in lymphoid organs of broiler chicken is by apoptosis.

Type 2 diabetes mellitus (T2DM) is characterized by a relative insulin deficiency or insulin resistance. It is also associated with a cluster of metabolic abnormalities, including hyper-tension and dyslipidemia. Although there are many studies that have studied the metabolic abnormalities in T2DM patients with metabolic syndrome (MetS), only few of them have assessed the metabolic abnormalities in their first-degree relatives (FDRs) who had MetS. The aim of this study is to compare the clinical and biochemical variables in T2DM subjects and their FDRs without diabetes in Benin City, Nigeria. This is a cross sectional case control study including 124 T2DM patients, 96 FDR of T2DM subjects, and 96 controls recruited using convenience sampling. Data were collected using a questionnaire-administered technique. Variables of interest that were assessed included anthropometric indices like waist circumference (WC), hip circumference (HC), waist:hip ratio (WHR), body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), serum lipid profile, fasting plasma glucose (FPG), hemoglobin A1c (HbA1c), proteinuria, and microalbuminuria. The 1999 World Health Organization (WHO) criteria were used to make a diagnosis of metabolic syndrome. The Chi-square test was used for comparison of proportions. P-value of less than 0.05 was taken as statistically significant. The student t-test was used to compare means and test for significant differences in the anthropometric and the metabolic indices. The prevalence of the MetS in T2DM persons was 87.1%, 16.7% in the FDR group, and 13.5% in the control group according to the WHO criteria. The mean value of HbA1c was significantly higher in T2DM subjects with MetS (p<0.05). The mean values of WC, FPG, total cholesterol, HDL cholesterol, and LDL cholesterol were higher in subjects with MetS in the T2DM group than in persons with MetS in the FDR group though not significant (p>0.05). The mean values of WHR, BMI, SBP, DBP, and triglyceride were higher in persons with the MetS in the FDR group than in persons with the MetS in the T2DM group. The difference in the BMI and SBP was significant (p<0.05). The prevalence of MetS in subjects with T2DM in Nigeria is very high. Though, all the biochemical and clinical indices were higher in T2DM subjects with MetS, the mean HbA1c, BMI, and SBP was significantly higher when compared to their FDR who also have MetS.

To explore the association between the C46T polymorphism of coagulation factor Ⅻ (FⅫ) gene and the involvement of FⅫ activity (FⅫ:C) in patients with unexplained recurrent spontaneous abortion (URSA), and to elucidate its role in the pathogenesis of URSA. This study included 203 patients with URSA (URSA group) and 171 healthy women with at least one child and no history of infertility or miscarriage (control group) in the southern area of Zhejiang Province. The C46T polymorphism of the FⅫ gene was analyzed with matrix-assisted laser desorption/ionization time of flight-mass spectrometry (MALDI-TOF-MS) in all subjects. The values of prothrombin time, activated partial thromboplastin time (APTT), fibrinogen, FⅫ:C and other coagulant parameters were determined. The frequency distribution of the wild-type (CC), heterozygote (CT), homozygote (TT) genotypes and C and T alleles were compared between the patients and controls. A comprehensive analysis of association was conducted between C46T genotypes and the FⅫ:C levels in URSA patients. The CC, CT, TT genotypes of the FⅫ gene were observed in 7 (3.4%, 7/203), 83 (40.9%, 83/203) and 113 (55.7%, 113/203) patients with URSA versus 7 (4.1%, 7/171), 46 (26.9%, 46/171) and 118 (69.0%, 118/171) controls. The frequency of CT in the patients with URSA was significantly higher than that in controls, but the frequency of TT in the patients was lower than that in controls (χ(2)=7.939, OR=1.884, 95%CI: 1.210-2.935, P<0.05). The frequencies of allele C and allele T were observed in 97 (23.9%, 97/406) and 309 (76.1%, 309/406) patients with URSA versus 60 (17.5%, 60/342) and 282 (82.5%, 282/342) controls. The distribution frequency of allele T in URSA group was lower than that in control group (χ(2)=4.510, OR=1.475, 95%CI: 1.029-2.115, P<0.05). The FⅫ: C levels in the patients were (102±13)% in CC genotype, (78±11)% in CT genotype and (59±9)% in TT genotype, respectively. The differences of the FⅫ: C levels between the CC and CT, CT and TT, CC and TT genotypes in the patients were significant (all P<0.05). The low level of FⅫ:C maybe result from the T allele of the FⅫ gene in URSA patients. The CT genotype might be relative to the pathogenesis of URSA in a Chinese Han female population from the southern area of Zhejiang province.

to investigate feasibility, safety and efficacy of home-based side-alternating whole body vibration (sWBV) to improve motor function in toddlers with cerebral palsy (CP). Randomized controlled trial including 24 toddlers with CP (mean age 19 months (SD±3.1); 13 boys). 14 weeks sWBV with ten 9-minute sessions weekly (non-individualized). Group A started with sWBV, followed by 14 weeks without; in group B this order was reversed. Feasibility (≥70% adherence) and adverse events were recorded; efficacy evaluated with the Gross Motor Function Measure (GMFM-66), Pediatric Evaluation of Disability Inventory (PEDI), at baseline (T0), 14 (T1) and 28 weeks (T2). Developmental change between T0 and T1 was similar in both groups; change scores in group A and B: GMFM-66 2.4 (SD±2.1) and 3.3 (SD±2.9) (p=0.412); PEDI mobility 8.4 (SD±6.6) and 3.5 (SD±9.2) (p=0.148), respectively. In two children muscle tone increased post-sWBV. 24 children received between 67 and 140 sWBV sessions, rate of completed sessions ranged from 48 to 100% and no dropouts were observed. A 14-week home-based sWBV intervention was feasible and safe in toddlers with CP, but was not associated with improvement in gross motor function.

Mild Class III malocciusions can be treated by upper incisor proclination and lower incisor retroclination following extraction of the lower first premolars. To compare the skeletal, dental and soft tissue changes in Class III patients treated with fixed appliances, Class III traction and lower first premolar extractions with the changes in a group of untreated Class III patients. The Treatment group consisted of 30 Class III patients (Mean age 13.69 +/- 1.48 years) who were treated by upper and lower fixed appliances, Class III intermaxillary traction and lower first premolar extractions for 2.88 +/- 1.12 years. The Control group consisted of 20 untreated Class III patients (Mean age 13.51 +/- 0.95) matched for age and gender. The T1 to T2 changes in the treated and untreated groups were compared using a paired t-test while differences between the two groups were compared with an independent t-test. During treatment, the upper incisors were proclined about 1 degree and the lower incisors were retroclined 8 degrees. Small, but statistically significant changes in SNB, Wits and the overlying soft tissues accompanied the changes in incisor inclination. At the end of treatment a positive overbite and overjet were achieved. The increase in lower facial height in the Treatment group was comparable with the change in the Control group. A range of mild to moderate Class III malocclusions can be treated by dentoalveolar compensation.

The aim of the present study was to observe the dynamic changes of the growth arrest and DNA damage-inducible 153 (GADD153) gene and caspase-12 in the brain tissue of rats with cerebral ischemia-reperfusion injury (CIRI) and the impact of curcumin pretreatment. A total of 60 rats were randomly divided into the normal group (N), the sham operation group (S), the dimethyl sulfoxide control group (D) and the curcumin treatment group (C). For group D and C, 12 (T1), 24 (T2) and 72 h (T3) of reperfusion were performed after 2 h ischemia. The expression levels of GADD153 and caspase-12 in the brain tissue were detected and compared among the groups by immunohistochemistry, immunofluorescence double staining and western blotting. The expression levels of GADD153 and caspase-12 were increased at T1compared with groups N and S, and the expression of caspase-12 peaked at T2 in group D, while GADD153 was increased until T3 in group D. Compared with group D, the expression levels of GADD153 and caspase-12 in group C at T2 and T3 were significantly decreased (P<0.05). Endoplasmic reticulum stress is involved in the pathological process of CIRI. Curcumin may decrease the expression levels of the above two factors, thus exhibiting protective effects against CIRI in rats. PMID:29067098

To gain insight into antiseptic effects on the concentrations of CO2, CH4, and N2O in lake water, antisepetic (CuSO4 and HgCl2) were added into water sample, and concentrations of greenhouse gases were measured by the gas chromatography based on water equilibrium method. Experiments were conducted as following: the control group without antisepetic (CK), the treatment group with 1 mL CuSO4 solution (T1), the treatment group with 5 mL CuSO4 solution (T2), and the treatment group with 0.5 mL HgCl2 solution (T3). All groups were divided into two batches: immediately analysis (I), and after 2 days analysis (II). Results showed that CuSO4 and HgCl2 significantly increased CO2 concentration, the mean CO2 concentration (Mco2) of CK (I) and CK (II) were (11.5 +/- 1.47) micromol x L(-1) and (14.38 +/- 1.59) micromol x L(-1), respectively; the Mco2 of T1 (I) and T1 (II) were (376 +/- 70) micromol x L(-1) and (448 +/- 246.83) micromol x L(-1), respectively; the Mco2 of T2 (I) and T2 (II) were (885 +/- 51.53) micromol x L(-1) and (988.83 +/- 101.96) micromol x L(-1), respectively; the Mco2 of T3 (I) and T3 (II) were (287.19 +/- 30.01) micromol x L(-1) and (331.33 +/- 22.06) micromol x L(-1), respectively. The results also showed that there was no difference in CH4 and N2O concentrations among treatments. Water samples should be analyzed as soon as possible after pretreatment. Our findings suggest that adding antiseptic may lead an increase in CO2 concentration.

The heme oxygenase-1 (HO-1) system is associated with the rate-limiting step of conversion of heme, one of the most critical roles in cytoprotective mechanisms. Our study investigated its potential role in protection of endothelial cells from T cells. The recombinant plasmid pcDNA3-HO-1 was transfected into endothelial cells. Indirect fluorescent staining was used to examine the expression of HO-1 protein. Then endothelial cells primed by INF-gamma were mixed in culture with Jurkat T cells labeled with carboxyfluorescein diacetate succinimidyl ester (CFSE). The number of adhesive Jurkat T cells was determined using FACS to evaluate the adhesion effect. After being cultured with endothelial cells, the cell cycle of Jurkat T cells was detected using FACS. Expression of HO-1 on endothelial cells conferred significant protection against Jurkat T-cell-mediated adhesion. The rate of Jurkat T-cell adhesions was reduced to 19.06%, in contrast with 31.42% in the control group (P<.05). After using ZnPP, an inhibitor of HO-1, the rate of Jurkat T-cell adhesion recovered to 29.08%. The binding activities between endothelial cells and Jurkat T cells was blocked by HO-1 expression. The proliferation of Jurkat T cells was inhibited after culture with endothelial cells, which had been transfected with HO-1, which blocked cell cycle entry of T cells. More than 60% of Jurkat T cells remained in G0/G1 compared with 40% among the control group. HO-1 directly protected endothelial cells primed by INF-gamma from Jurkat T cells and down-regulated the expression of HLA-DR on the surface of endothelial cells. These results indicated that transgenic expression of HO-1 may be useful to prevent lymphocytes from responding to endothelial cells.

This study aimed to investigate the effects of manganese (Mn) supplementation on nutrient digestibility and antler growth in male sika deer. Twenty 3-year-old male sika deer were divided into four groups (Control, T40, T80 and T120). The control diet contained 22.2 mg Mn/kg. The treatment diets were supplemented with 40, 80 and 120 mg of Mn/kg (provided as Mn methionine). The results showed that the digestibility of dry matter and crude protein in the T80 group was greater than other groups. Higher digestibility of neutral detergent fiber and acid detergent fiber was observed in the T80 group than in the control group. Plasma Mn concentrations in the T80 and T120 groups were higher (P < 0.01) than control and T40 group (P < 0.01). The concentration of Mn in feces was increased with increasing Mn amount. Average daily gain of fresh antler and dry antler of T80 was greater than other groups, especially the control group (P < 0.05). In conclusion, the suitable level of Mn supplementation was found to be 80 mg/kg (total Mn content 103.4 mg/kg dry matter), which significantly increased antler daily gain and feed digestibility in 3-year-old sika deer. © 2016 Japanese Society of Animal Science.

An effective intervention program aiming to reduce whole body vibration (WBV) exposure at work will reduce the number of low back complaints in the near future. An evaluation study with a controlled pretest-post-test design. Nine companies and 126 drivers were included in the study. Cluster randomization on company level divided the drivers and their employers in an intervention group and a "care-as-usual" group. At baseline (T0) and intervention program was implemented and evaluated after 7 months (T1). The main outcome measure was WBV exposure. Process measures included knowledge, attitude, and (intended) behavior towards reduction of WBV exposure for the drivers and knowledge and WBV policy for the employers. At T1, no significant reduction was found in WBV exposure within both groups compared with T0. Probably due to poor to moderate compliance, the intervention program was not effective in reducing the WBV exposure on group level but small reductions in WBV exposure are possible when intervention compliance is high.

To determine whether cumulative anodal transcranial direct current stimulation (A-tDCS) of the left dorsolateral prefrontal cortex (DLPFC) could enhance rehabilitation of memory and attention in patients with traumatic brain injury (TBI). Inpatient and outpatient neurorehabilitation unit. Twenty-three adult patients, 4- to 92- months post severe TBI. Participants were randomly allocated to 2 groups. The experimental group received A-tDCS (10 minutes; 1 mA; in the DLPFC), followed by rehabilitative cognitive training, daily for 15 days. Controls received A-tDCS for 25 seconds (sham condition) with the same rehabilitation. Battery of memory and attention tests, which included visual and auditory modalities. Participants were tested twice before beginning rehabilitation (to control for spontaneous recovery), after rehabilitation completion, and 4 months later. Tests scores in both groups were similar at 3 weeks before and immediately before treatment. After treatment, the experimental group exhibited larger effect sizes in 6 of 8 cognitive outcome measures, but they were not significantly different from controls. At follow-up, differences remained insignificant. In contrast to previous studies, our study did not provide sufficient evidence to support the efficacy of repeated A-tDCS for enhancing rehabilitation of memory and attention in patients after severe TBI.

To observe the effects of silkworm pupa oil on serum lipids level and platelet function in rats, according to serum TG, TC level, 40 male Wistar rats are divided into four groups (normal control group, high fat control group, silkworm pupa oil group and silkworm pupa oil + VE group). The rats are fed different diets and six weeks later, serum lipids level and platelet function are measured. The results show that (1) Compared with high fat control group, serum TC, TG, LDL-C level, AI value, Platelet aggregability, plasma TXB2 level and T/P ratio decrease significantly while HDL-C level and 6-k-PGF1 level increase in silkworm pupa oil group; (2) Serum TC, LDL-C level, T/P ratio and platelet aggregability are significantly lower in silkworm pupa oil + VE group than in silkworm pupa oil group. It is suggested that silkworm pupa oil rich in alpha-linolenic acid can reduce serum lipids level and inhibit platelet aggregation, which is more effective with the supplementation with VE.

Substantial numbers of women with past gestational diabetes mellitus (GDM) develop type 2 diabetes mellitus (T2DM). In northern New South Wales 23% of women attending diabetes services between 2007 and 2010 with T2DM previously had GDM. This study investigated whether phone-based lifestyle education using motivational interviewing resulted in positive lifestyle change post GDM for women in a large rural area. Thirty-eight women were recruited to this pilot study following GDM diagnosis and randomly allocated to either the control or intervention group. Following baseline assessment, the intervention group received a 6-month phone-based motivational interviewing program, and access to usual care. The control group received usual care only. Measures were collected at baseline (6 weeks postnatal), and at 6 months follow-up. Outcome measures included body mass index, diet, and physical activity. At follow-up, the intervention group compared to the control group significantly reduced total fat intake by -19 g/d (95%CI: -37 to -1), total carbohydrate intake by -42 g/d (95%CI: -82 to -1), and glycaemic load by -26 units (95%CI: -48 to -4). These women also increased leisure physical activity compared to the control group by 11 min/d (95%CI: 1 to 22); no significant change in total physical activity levels occurred. At follow-up, body mass index in the intervention group improved by -1.5 kg/m2 (95%CI: -2.8 to -0.1) compared to the control group. The intervention group showed positive trends across lifestyle variables compared to the control group. Further large-scale research on the effectiveness of phone-based lifestyle counselling following GDM is warranted.
