Two hundred thirty-eight first-year college students were assessed using the Beck Depression Inventory (BDI). Thirty students meeting the BDI criteria for moderate to severe depression were randomly assigned to either a treatment or control group. The treatment group received four 90-minute group sessions of EFT (Emotional Freedom Techniques), a novel treatment that combines exposure, cognitive reprocessing, and somatic stimulation. The control group received no treatment. Posttests were conducted 3 weeks later on those that completed all requirements (N = 18). The EFT group (n = 9) had significantly more depression at baseline than the control group (n = 9) (EFT BDI mean = 23.44, SD = 2.1 versus control BDI mean = 20.33, SD = 2.1). After controlling for baseline BDI score, the EFT group had significantly less depression than the control group at posttest, with a mean score in the "nondepressed" range (P = .001; EFT BDI mean = 6.08, SE = 1.8 versus control BDI mean = 18.04, SE = 1.8). Cohen's d was 2.28, indicating a very strong effect size. These results are consistent with those noted in other studies of EFT that included an assessment for depression and indicate the clinical usefulness of EFT as a brief, cost-effective, and efficacious treatment.

This study examined long-term follow-up effects of participation in the HomeStyles RCT, using Social Cognitive Theory constructs, on physical activity cognitions, home environment, and lifestyle behavioral practices of families with preschool children (ages 2 to 5 years). Parents were systematically randomized to experimental or attention control group at baseline. Those completing all surveys that comprised of valid, reliable measures were the analytic sample (n = 61 experimental, n = 63 control; mean age 32.8 ± 5.9SD years). Repeated measures ANCOVA, controlling for prognostic variables (e.g., parent sex) revealed that variables assessing modeling of physical activity for children increased significantly (P ≤ .01) in both groups with no significant time by group effects. Paired t-tests indicated the experimental group's self-efficacy for keeping children's weight healthy and performing health promoting behaviors increased significantly over time whereas the control group did not but with no significant time by group effects. Self-regulation paired t-test findings indicated that total screentime the experimental group allowed children decreased significantly over time with no significant time by group effect. The value parents placed on physical activity for children increased over time in both groups with a significant time effect. The experimental group over time had significantly greater increases in the availability of physical activity space and supports inside the home than the control group. Improvements noted have the potential to help protect children and parents from excess weight gain, yet findings indicate considerable opportunity for continued improvement as well as elucidation of factors affecting concomitant changes in both study groups.

Training in practical aspects of disaster medicine is often impossible, and simulation may offer an educational opportunity superior to traditional didactic methods. We sought to determine whether exposure to an electronic simulation tool would improve the ability of medical students to manage a simulated disaster. We stratified 22 students by year of education and randomly assigned 50% from each category to form the intervention group, with the remaining 50% forming the control group. Both groups received the same didactic training sessions. The intervention group received additional disaster medicine training on a patient simulator (disastermed.ca), and the control group spent equal time on the simulator in a nondisaster setting. We compared markers of patient flow during a simulated disaster, including mean differences in time and number of patients to reach triage, bed assignment, patient assessment and disposition. In addition, we compared triage accuracy and scores on a structured command-and-control instrument. We collected data on the students' evaluations of the course for secondary purposes. Participants in the intervention group triaged their patients more quickly than participants in the control group (mean difference 43 s, 99.5% confidence interval [CI] 12 to 75 s). The score of performance indicators on a standardized scale was also significantly higher in the intervention group (18/18) when compared with the control group (8/18) (p < 0.001). All students indicated that they preferred the simulation-based curriculum to a lecture-based curriculum. When asked to rate the exercise overall, both groups gave a median score of 8 on a 10-point modified Likert scale. Participation in an electronic disaster simulation using the disastermed.ca software package appears to increase the speed at which medical students triage simulated patients and increase their score on a structured command-and-control performance indicator instrument. Participants indicated that the simulation-based curriculum in disaster medicine is preferable to a lecture-based curriculum. Overall student satisfaction with the simulation-based curriculum was high.

The implementation of interdisciplinary teams in the intensive care unit (ICU) has focused attention on leadership behavior. Daily interdisciplinary rounds (IDRs) in ICUs integrate leadership behavior and interdisciplinary teamwork. The purpose of this intervention study was to measure the effect of leadership training on the quality of IDRs in the ICU. A nonrandomized intervention study was conducted in four ICUs for adults. The intervention was a 1-day training session in a simulation environment and workplace-based feedback sessions. Measurement included 28 videotaped IDRs (total, 297 patient presentations) that were assessed with 10 essential quality indicators of the validated IDR Assessment Scale. Participants were 19 intensivists who previously had no formal training in leading IDRs. They were subdivided by cluster sampling into a control group (ten experienced intensivists) and intervention group (nine intensive care fellows). Mann-Whitney U test was used to compare results between control and intervention groups. Baseline measurements of control and intervention groups revealed two indicators that differed significantly. The frequency of yes ratings for the intervention group significantly increased for seven of the ten indicators from before to after intervention. The frequency of yes ratings after training was significantly greater in the intervention than control groups for eight of the ten essential quality indicators. The leadership training improved the quality of the IDRs performed in the ICUs. This may improve quality and safety of patient care.

This study aimed to evaluate the effects of treatment with different powers of Nd: YAG laser irradiation on root surfaces and Streptococcus mutans (S. mutans) adhesion. Extracted teeth because of severe periodontal disease were divided into the following four groups: control group, laser group 1, laser group 2, and laser group 3. After scaling and root planning, laser group 1, laser group 2, and laser group 3 were separately treated with Nd: YAG laser irradiation (4/6/8 W, 60 s); however, the control group did not receive the treatment. Scanning electron microscopy (SEM) was used to determine the morphology. S. mutans were cultured with root slices from each group. Colony forming unit per mL (CFU·mL⁻¹) was used to count and compare the amounts of bacteria adhesion among groups. SEM was used to observe the difference of bacteria adhesion to root surfaces between control group (scaling) and laser group 2 (6 W, 60 s), thereby indicating the different bacteria adhesions because of different treatments. Morphology alterations indicated that root surfaces in control group contain obvious smear layer, debris, and biofilm; whereas the root surfaces in laser group contain more cracks with less smear layer and debris. The bacteria counting indicated that S. mutans adhesion to laser group was weaker than that of control group (P<0.05). No statistical significance among the laser groups (P>0.05) was observed. Morphology alterations also verified that S. mutans adhesion to laser group 2 (6 W, 60 s) was weaker than that of control group (scaling). This study demonstrated that Nd: YAG laser irradiation treatment after scaling can reduce smear layer, debris, and biofilm on the root surfaces as compared with conventional scaling. The laser treatment reduces the adhesion of S. mutans as well. However, Nd: YAG laser irradiation can cause cracks on the root surfaces. In this experiment, the optimum laser power of 6 W can thoroughly remove the smear layer and debris, as well as relatively improve the control of thermal damagee.

Case-control studies to quantify oral cholera vaccine effectiveness (VE) often rely on neighbors without diarrhea as community controls. Test-negative controls can be easily recruited and may minimize bias due to differential health-seeking behavior and recall. We compared VE estimates derived from community and test-negative controls and conducted bias-indicator analyses to assess potential bias with community controls. From October 2012 through November 2016, patients with acute watery diarrhea were recruited from cholera treatment centers in rural Haiti. Cholera cases had a positive stool culture. Non-cholera diarrhea cases (test-negative controls and non-cholera diarrhea cases for bias-indicator analyses) had a negative culture and rapid test. Up to four community controls were matched to diarrhea cases by age group, time, and neighborhood. Primary analyses included 181 cholera cases, 157 non-cholera diarrhea cases, 716 VE community controls and 625 bias-indicator community controls. VE for self-reported vaccination with two doses was consistent across the two control groups, with statistically significant VE estimates ranging from 72 to 74%. Sensitivity analyses revealed similar, though somewhat attenuated estimates for self-reported two dose VE. Bias-indicator estimates were consistently less than one, with VE estimates ranging from 19 to 43%, some of which were statistically significant. OCV estimates from case-control analyses using community and test-negative controls were similar. While bias-indicator analyses suggested possible over-estimation of VE estimates using community controls, test-negative analyses suggested this bias, if present, was minimal. Test-negative controls can be a valid low-cost and time-efficient alternative to community controls for OCV effectiveness estimation and may be especially relevant in emergency situations.

The impact on tilapia fish of combined treatment of landfill leachate and domestic sewage was monitored in a waste treatment plant that operated on a pilot scale using the activated sludge process. Biomarkers of sub-lethal toxicity were used to indicate the possibility of damage to organisms due to interaction with pollutants. The concentration of metallothioneins did not indicate the increased presence of metals in fish exposed than in control groups. Acetylcholinesterase enzyme activity was inhibited in only one of the exposed groups, indicating the possible presence of organophosphate and/or carbamate pesticides in treated effluent. The PAHs used as biomarkers (naphthalene, pyrene, benzo(a)pyrene and 1-hydroxypyrene) indicated that exposed fish had a greater absorption of PAHs than control groups of fish, indicating the likely presence of these compounds in at least one of the combined treatment effluents. The frequencies of micronuclei and other erythrocytic nuclear abnormalities also indicate greater genotoxic damage in cells of organisms exposed than in control groups. The use of biomarkers proved to be important to permit an evaluation of sub-lethal damage present in organisms exposed to the pollution source studied.

Oral lichen planus (OLP) is a common inflammatory disease with unknown etiology. Depression, stress and anxiety are psychological factors that their influence on the expression of lichen planus by affecting the immune system's function has been confirmed. There is a probable relationship between anger and OLP expression. Therefore, the present study aimed to evaluate the association of "anger" and OLP. In this descriptive study 95 subjects were included in 3 groups. A: patients with oral lichen planus, B: positive control, C: negative control. Anger and its indices were assessed by the State-Trait Anger Expression Inventory-2 (STAXI-2) questionnaire, and pain was measured via the Visual Analogue Scale (VAS). The collected data were analyzed statistically using SPSS 18 software. The lichen planus and positive control groups bore higher total anger index (AX index) values compared with the negative control. Comparing anger expression-in (AXI) among the lichen planus and negative control groups revealed higher grades in lichen planus group. Evaluating the pain severity index (VAS) data and anger indices in lichen planus group, Spearman's Rank Correlation Test revealed a significant correlation between TAngR (reactional anger traits) and pain severity. The findings of this study indicated that there was a significant correlation between anger control and suppression of lichen planus development. On the other hand, the patients with more severe pain mostly expressed their anger physically. Based on the findings, we can make the claim that anger suppression and its control-in (gathering tension) may play a role in the development of lichen planus as a known psychosomatic disorders.

Background. Subjects with type 2 diabetes mellitus (DM2) require an adequate glycemic control to avoid diabetic complications. Currently, saliva biomarkers are used as a diagnostic tool and can be indicative of the degree of progression and control of various diseases. Several studies indicate that α-2-macroglobulin levels are elevated in diabetic patients. Methods. 120 subjects with DM2 were enrolled and classified into two groups according to their glycemic control (percentage of glycated hemoglobin-A1c (HbA1c), <7% adequate glycemic control group; >7% inadequate glycemic control group). The relationship between α-2-macroglobulin levels from saliva samples and HbA1c was subsequently evaluated. Results. We found a positive correlation between α-2-macroglobulin and HbA1c (r = 0.778 and P < 0.0001). Area under the receivers operating characteristic (ROC) curve of α-2-macroglobulin indicated a positive discrimination threshold of α-2-macroglobulin (AUC = 0.903, CI 95%: 0.847–0.959, P < 0.0001) to diagnose glycemic control. Conclusions. Our data strongly suggest that the level of saliva α-2-macroglobulin is an indicator for the degree of glycemic control in diabetic patients and represents a promising alternative method to evaluate this parameter.

Oral hygiene and health of the institutionalized elderly are frequently described as inadequate. This randomized and single-blinded (outcome evaluation) study compared three types of intervention for improving oral hygiene with a control. The purpose was to investigate whether there were any significant differences between the intervention and control groups. One hundred and six participants living in long-term care homes in South-West Germany were recruited and randomly divided into four groups-three therapy groups and one control group. For all three therapy groups, teeth and dentures were cleaned professionally and individual instruction was given. One of these groups was also re-instructed and remotivated by a dentist (n = 27). One also received help from, and was remotivation by, staff educated in dental hygiene (n = 26). The third therapy group was not remotivated after professional cleaning of teeth and dentures (n = 26). For the control group, there was no intervention (n = 23). The main target clinical data were mean plaque (plaque-control record, O'Leary), gingival bleeding (Ainamo/Bay), and denture hygiene indices. For assessment of the difference between being in an intervention group and in a control group, mixed-model analysis for repeated measurements was performed for each main target variable. In addition, target clinical data were evaluated in long-term follow-up after 3 years. Compared with controls, denture hygiene, plaque, and gingival bleeding indices were significantly lower in the intervention groups over a twelve-week period (mixed model for repeated measurements; P < 0.023). Estimates of effects between control and each treatment group were comparable among the three therapy groups; however, even though two of the groups received further help and instruction. Long-term follow-up showed that all indices were significantly worse than at the last study recall (P < 0.001). Professional cleaning of teeth and dentures, with individual instruction, can be recommended to improve oral hygiene. However, the effect decreases over time and renewal of the intervention is necessary. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The chemopreventive activity of an extract of Withania somnifera (WS) roots was examined in female Sprague-Dawley rats that received the mammary carcinogen methylnitrosourea (MNU). The dose of the extract, administered by gavage, was 150 mg/kg body weight daily for 155 days after injection of MNU. Rats in the treated group (N=15) had an average of 3.47 tumors, and rats in the control group (N=15) had 4.53, a reduction of 23%. The average weights of tumors were 4.98 g for rats in the treated group and 6.30 g for the controls, a difference of 21%. Labeling indices for Ki67 and proliferating cell nuclear antigen (PCNA) markers in cancers of the treated group were 42% and 38% lower, respectively, than those of the corresponding indices for the control group. These results indicate that the root extract significantly reduced the rate of cell division in the mammary tumors. PMID:23564793

In time, well water, as a source of drinking and coking water, with physical-chemical, bacteriological, and biological indicators suggestive of alteration in water potability, determines complex, sometimes irreversible, metabolic disorders. Sixty individuals residing in a rural community were divided into 2 groups: study group -30 subjects using well water, and control group--30 subjects using safe water. For the study group the selection criteria were: age, sex, use of well water as drinking and cooking water, history suggestive of chronic poisoning (pregnancy course, birth weight, susceptibility to infectious agents, and current chronic diseases). In the study group, gestosis, prematurity, and altered body mass index are more frequent as compared to the subjects in the control group. The identified laboratory changes indicate moderate anemia, hepatic cytolysis, dyslipidemia, presence of nitrites in urine, and positive urine cultures. Long-term use of water with mineral constituents in excess, absent, or inadequate, the direct biological and chemical water pollution, or most frequently the indirect pollution through the soil determine, in time, complex, sometimes irreversible, metabolic disorders.

Introduction Surgical services are increasingly seen to reduce death and disability in Sub-Saharan Africa, where hospital-based mortality remains alarmingly high. This study explores two implementation approaches to improve the quality of perioperative care in a Tanzanian hospital. Effects were compared to a control group of two other hospitals in the region without intervention. Methods All hospitals conducted quality assessments with a Hospital Performance Assessment Tool. Changes in immediate outcome indicators after one and two years were compared to final outcome indicators such as Anaesthetic Complication Rate and Surgical Case Fatality Rate. Results Immediate outcome indicators for Preoperative Care in the intervention hospital improved (52.5% in 2009; 84.2% in 2011, p<0.001). Postoperative Inpatient Care initially improved to then decline again (63.3% in 2009; 70% in 2010; 58.6% in 2011). In the control group, preoperative care declined from 50.8% (2009) to 32.8% (2011, p <0.001), while postoperative care did not significantly change. Anaesthetic Complication Rate in the intervention hospital declined (1.89% before intervention; 0.96% after intervention, p = 0.006). Surgical Case Fatality Rate in the intervention hospital declined from 5.67% before intervention to 2.93% after intervention (p<0.0010). Surgical Case Fatality Rate in the control group was 4% before intervention and 3.8% after intervention (p = 0.411). Anaesthetic Complication Rate in the control group was not available. Discussion Immediate outcome indicators initially improved, while at the same time final outcome declined (Surgical Case Fatality, Anaesthetic Complication Rate). Compared to the control group, final outcome improved more in the intervention hospital, although the effect was not significant over the whole study period. Documentation of final outcome indicators seemed inconsistent. Immediate outcome indicators seem more helpful to steer the Continuous Quality Improvement program. Conclusion Specific interventions as part of Continuous Quality Improvement might lead to sustainable improvement of the quality of care, if embedded in a multi-faceted approach. PMID:26327392

2015-12-17

In patients with traumatic brain injury, hypothermia can reduce intracranial hypertension. The benefit of hypothermia on functional outcome is unclear. We randomly assigned adults with an intracranial pressure of more than 20 mm Hg despite stage 1 treatments (including mechanical ventilation and sedation management) to standard care (control group) or hypothermia (32 to 35°C) plus standard care. In the control group, stage 2 treatments (e.g., osmotherapy) were added as needed to control intracranial pressure. In the hypothermia group, stage 2 treatments were added only if hypothermia failed to control intracranial pressure. In both groups, stage 3 treatments (barbiturates and decompressive craniectomy) were used if all stage 2 treatments failed to control intracranial pressure. The primary outcome was the score on the Extended Glasgow Outcome Scale (GOS-E; range, 1 to 8, with lower scores indicating a worse functional outcome) at 6 months. The treatment effect was estimated with ordinal logistic regression adjusted for prespecified prognostic factors and expressed as a common odds ratio (with an odds ratio <1.0 favoring hypothermia). We enrolled 387 patients at 47 centers in 18 countries from November 2009 through October 2014, at which time recruitment was suspended owing to safety concerns. Stage 3 treatments were required to control intracranial pressure in 54% of the patients in the control group and in 44% of the patients in the hypothermia group. The adjusted common odds ratio for the GOS-E score was 1.53 (95% confidence interval, 1.02 to 2.30; P=0.04), indicating a worse outcome in the hypothermia group than in the control group. A favorable outcome (GOS-E score of 5 to 8, indicating moderate disability or good recovery) occurred in 26% of the patients in the hypothermia group and in 37% of the patients in the control group (P=0.03). In patients with an intracranial pressure of more than 20 mm Hg after traumatic brain injury, therapeutic hypothermia plus standard care to reduce intracranial pressure did not result in outcomes better than those with standard care alone.

2018-04-01

The aim was to elucidate the impact of Royal Jelly (RJ) on behavioural patterns, feather cover, egg quality and some blood haematological indices in laying hens (58-64 weeks of age). A total of 108 Tetra Brown laying hens were used in the current trial. The birds were divided into three equal groups (36 birds each). The pure RJ was prepared for immediate injection subcutaneously, as follows: the first treated group (RJ 1 :100 mg/kg); the second treated group (RJ 2 :200 mg/kg); the control group. The eating and drinking activities in the RJ 2 group were significantly (p = .009 and .015 respectively) higher than the control and RJ 1 groups. Furthermore, the aggressive pecks, feather pecks and threating behaviour in the RJ 2 group were significantly (p = .005, .001 and .039 respectively) lower than the control and RJ 1 groups. Both RJ-treated groups had the best feather cover on the neck and abdomen regions (p = .010 and .001 respectively; Figure ). Both RJ-treated groups had a significantly higher eggshell ratio (p = .019) and shell thickness (p = .001) in comparison with the control group. The albumen height, Haugh units and yolk index in both RJ-treated groups were significantly greater than those recorded in the control group (p = .026, .001 and .022 respectively). The erythrocyte and total leucocyte counts in the RJ 2 group were significantly higher than those reported in the control and RJ 1 groups (p = .029 and .013 respectively); however, the heterophil/lymphocyte (H/L) ratio and heterophil % in both RJ-treated groups were significantly the lowest (p = .001 and .039). In conclusion, birds in the RJ 2 group had superior feather cover, welfare and behavioural indices, probably due to the impact of active flavonoids components of RJ on laying hen performance. Furthermore, the RJ-treated groups had significantly improved egg quality parameters and some blood haematological indices. © 2017 Blackwell Verlag GmbH.

A combination of radio-frequency (RF) and ultrasound cavitation (UC) has been reported to reduce indices of obesity. In this study, we aimed to investigate the effect of a combination of these techniques on anthropometric indices, pro-oxidant-antioxidant balance (PAB), and serum high-sensitivity C-reactive protein (hs-CRP). This randomized clinical trial was performed on 50 healthy women between January 2014 and June 2014 in Ghaem Hospital, Mashhad, Iran. Participants were randomized to one of two groups, both of which received a low-calorie diet containing 500-kcal energy deficit per day. The trial group included twenty-five subjects who were assigned to the combined treatment of RF and ultrasound cavitation program of abdomen and flank areas. There were twenty-five control subjects who received the low calorie diet alone. Biochemical markers, including serum hs-CRP and PAB values, and anthropometric indices were measured in the intervention group and healthy controls. For both the intervention and control groups, waist circumference was reduced significantly by 3.76 ± 1.69 and 2.40 ± 1.04, respectively (P < 0.05). In addition, abdominal circumference was reduced by 9.5 ± 2.66 and 3.12 ± 1.88, in these groups, respectively (P < 0.001). Decrement of PAB level in the intervention group, and its increment in the control group, were not significant (P > 0.05). In addition, reductions of hs-CRP and PAB between the two studied groups during five weeks of study were not significant (P > 0.05). Although there were significant reductions in anthropometric indices following treatment with RF and UC, the effects on serum PAB or hs-CRP were no significantly different, compared to the control group. Further studies are needed to confirm the beneficial effect for the use of these techniques.

Locked anterior shoulder (LAS) with static instability and anterior glenoid bone loss is challenging in the elderly population. Reverse shoulder arthroplasty (RSA) has been employed in treating these patients. No study has compared RSA for LAS with classically indicated RSA. A retrospective case-control study of patients treated with RSA for LAS with glenoid bone loss and static instability was performed using matched controls treated with primary RSA for classic indications. Twenty-four cases and 48 controls were evaluated. Average follow-up was 25.5 months, and median age was 76 years. Motion, outcome assessments, and postoperative radiographs were compared. Preoperatively, LAS had significantly less rotation and lower baseline outcome scores. Glenoid bone grafting was more common (P = .05) in the control group (26%) than in the LAS group (6.3%). Larger glenospheres were used more often (P = .001) in the LAS group (75%) than in the control group (29%). Both groups demonstrated significant improvements in pain, function, and outcome scores. Postoperatively, the control group had significantly better elevation and functional outcome scores. With the exception of flexion and Simple Shoulder Test score, effectiveness of treatment was similar between groups. Postoperative acromion stress fractures were seen in 21% of LAS patients and 9% of controls (P = .023) with a predominance of type 3 fractures in LAS. Two LAS patients remained dislocated. Patients with LAS treated with RSA can anticipate improvements in pain and function by use of larger glenospheres, often without the need for glenoid bone grafting. Worse postoperative motion and function and a higher incidence of acromion stress fracture may be expected. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

We explored the relationship between structural neuroimaging-based indices of cerebral integrity and executive control function (ECF) in two groups of healthy subjects: A maturing group (33 subjects; 19–29 years) and a senescing group (38 adults; 30–90 years). ECF was assessed using the Executive Interview (EXIT) battery. Cortical indices of cerebral integrity included GM thickness, intergyral span, and sulcal span, each measured for five cortical regions per hemisphere. Subcortical indices included fractional anisotropy (FA), measured using track-based-spatial-statistics (TBSS), and the volume of T2-hyperintense WM (HWM). In the maturing group, no significant relationships between neuroanatomical changes and ECF were found; however, there were hints that late-term maturation of cerebral WM influenced variability in ECF. In the senescing group, the decline in ECF corresponded to atrophic changes in cerebral WM (sulcal and intergyral span) primarily in the superior frontal and anterior cingulate regions. A large fraction of the variability in ECF (62%) can be explained by variability in the structural indices from these two regions. PMID:19067326

A significant correlation between hypertension history and high blood pressure has been observed with regard to age, race and gender. Investigating carotid intima-media thickness and aortic stiffness prior to the development of hypertension in children of hypertensive parents enabled us to evaluate these patients for subclinical atherosclerosis. We compared carotid intima-media thickness, aortic strain, distensibility, stiffness indices and elastic modulus in 67 normotensive children whose parents had a diagnosis of essential hypertension and 39 normotensive children with no parental history of hypertension. Although there were no significant differences between the two groups in terms of systolic blood pressure, diastolic blood pressure, average blood pressure and pulse pressure (P>0.05), systolic blood pressures were higher among patients 15 years and older in the study group. No significant differences were noted between the control and study groups regarding interventricular septal thickness, left-ventricular posterior wall thickness, left-ventricular systolic and diastolic diameter and aortic annulus diameter (P>0.05). The left atrium diameter was larger in the study group compared with that in the control group, mainly because of the values of the 15-year-old and older children (P=0.01). The mean, maximum and minimum values of carotid intima-media thickness were significantly different in the study group compared with the control group among all age groups (P<0.001, P<0.001, P=0.006, respectively). Aortic systolic and diastolic diameters were larger in normotensive children of hypertensive parents compared with the control group (P=0.014, P=0.001, respectively). Although there were no differences between the study and control groups regarding aortic strain, aortic distensibility, elastic modulus and stiffness indices (P>0.05), aortic distensibility was lower, and aortic stiffness indices were higher among children 15 years and older in the study group. An increase in the carotid intima-media thickness in all age groups and a decrease in aortic elastic properties in 15-year-old and older children of hypertensive parents may indicate subclinical atherosclerosis in these apparently healthy children.

The aim of this study was to investigate the effect of dietary supplementation of nanoparticle trivalent chromium on nutrient utilization, growth performance and serum traits of broilers. This study included two trials. In trial 1, 32 three-week-old broilers were divided into four groups: the control, chromium chloride (CrCl3), chromium picolinate (CrPic) and nanoparticle chromium picolinate (NanoCrPic). Chromium was added at a 1200 μg/kg level to evaluate the nutrient and chromium utilization. In trial 2, 160 one-day-old broilers were randomly divided into four groups as in trial 1, with four replicates. The results of trial 1 indicated that the chromium utilization is as follows: NanoCrPic > CrPic > CrCl3 and control groups, with significant differences between groups (p < 0.05). Crude fat utilization in CrCl3 group was lower than in that the control group (p < 0.05). The results of trial 2 indicated that feed intake of 4-5 weeks showed better result in the CrCl3 group than that in the CrPic group (p < 0.05). The results of serum traits indicated that the LDL-cholesterol in the NanoCrPic groups was lower than that in the CrPic group (p < 0.05). The NanoCrpic and CrPic groups showed significantly increased serum chromium concentration when compared with the control and CrCl3 groups; the triglyceride level in the CrCl3 group was lower than that in the CrPic group (p < 0.05). This study concluded that compared with CrPic, NanoCrpic supplementation could increase chromium utilization and lower the serum LDL-cholesterol of broilers.

The present prospective clinical study was undertaken to determine the usefulness of midluteal phase serum immunoreactive alpha-inhibin concentrations as markers of luteal phase deficiency and whether they are better indicators of biopsy confirmed luteal phase defect than serum progesterone. Consecutive patients (n = 138) with regular menstrual cycles attending our Infertility Clinic (experimental group) and 15 fertile women who were requesting contraception and had regular menstrual patterns (control group) were included. In all women (patients and controls), basal body temperature, midluteal serum concentrations of oestradiol, prolactin, progesterone and immunoreactive alpha-inhibin, and premenstrual endometrial biopsy were used in the same cycle to assess luteal function. Out-of-phase secretory endometria were detected in 15 of the 138 patients. Thus, hormonal concentrations were compared between the following three groups of women: group 1 (n = 15), infertile patients with defective secretory endometria; group 2 (n = 123), infertile patients with normal secretory endometria; and controls (n = 15), fertile women with normal secretory endometria. Midluteal serum concentrations of progesterone, immunoreactive alpha-inhibin, oestradiol, and prolactin of the two groups studied were similar to those of the control group of fertile women. Our results indicate that midluteal serum inhibin determination does not accurately reflect histological maturation of the endometrium and it is not a better indicator of endometrial luteal phase deficiency than midluteal serum progesterone concentration.

To determine whether a home-based multicomponent physical activity counseling (PAC) intervention is effective in reducing glycemic measures in older outpatients with prediabetes mellitus. Controlled clinical trial. Primary care clinics of the Durham Veterans Affairs (VA) Medical Center between September 29, 2008, and March 25, 2010. Three hundred two overweight (body mass index 25-45 kg/m(2) ), older (60-89) outpatients with impaired glucose tolerance (fasting blood glucose 100-125 mg/dL, glycosylated hemoglobin (HbA1c) <7%) randomly assigned to a PAC intervention group (n = 180) or a usual care control group (n = 122). A 12-month, home-based multicomponent PAC program including one in-person baseline counseling session, regular telephone counseling, physician endorsement in clinic with monthly automated encouragement, and customized mailed materials. All study participants, including controls, received a consultation in a VA weight management program. The primary outcome was a homeostasis model assessment of insulin resistance (HOMA-IR), calculated from fasting insulin and glucose levels at baseline and 3 and 12 months. HbA1c was the secondary indicator of glycemic control. Other secondary outcomes were anthropometric measures and self-reported physical activity, health-related quality of life, and physical function. There were no significant differences between the PAC and control groups over time for any of the glycemic indicators. Both groups had small declines over time of approximately 6% in fasting blood glucose (P < .001), and other glycemic indicators remained stable. The declines in glucose were not sufficient to affect the change in HOMA-IR scores due to fluctuations in insulin over time. Endurance physical activity increased significantly in the PAC group (P < .001) and not in the usual care group. Home-based telephone counseling increased physical activity levels but was insufficient to improve glycemic indicators in older outpatients with prediabetes mellitus. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

The shape of the patella has been considered to be a predisposing factor resulting in patellar instability, but the effects of abnormal patella position during its development are unclear. The present study evaluated patellar morphological changes after patella instability and evaluated the influence of patellar instability on the patella shape. Twenty rabbits that were 2 months old were included in the study. The left knee of each rabbit, defined as the experimental group (N = 20 knees/group), underwent a medial soft tissue restraint release. The right knee of each rabbit, defined as the control group (N = 20 knees/group), did not undergo any surgical procedures. A CT scan was performed on each knee before surgery and 6 months post-surgery to measure the transverse diameter, thickness, Wiberg index, and Wiberg angle for analysis of the patellar morphological changes. Cross-specimen examination was conducted to evaluate the differences between the experimental group and the control group. The four indices remained the same between the two groups before surgery. However, 6 months after surgery, the mean transverse diameter of the patellae in the experimental group was significantly longer than that in the control group (P < 0.001), while the mean thickness in the experimental group was not significantly greater than that in the control group (P = 0.314), resulting in a flattened shape. The Wiberg indices were not significantly different between the two groups. However, the mean Wiberg angle was higher in the experimental group than in the control group (P < 0.001), which resulted in a flattened articular surface of the patella. The sectional shape and articular surface of the patella became more flattened after patella instability in this study, which indicates that patella dysplasia could be caused by patella instability. Clinically, early intervention for adolescent patients with patella instability is important.

To analyze the clinical outcomes following the implementation of a new standard labor procedure. This was a retrospective analysis that included a study group consisting of patients managed based on a new standard labor protocol and a control group comprising patients managed under an old standard labor protocol. The following maternal and perinatal outcomes were compared in the two groups: the indications for a cesarean section and the incidence of cesarean section, postpartum hemorrhage, fetal distress, neonatal asphyxia and pediatric intervention. We also compared the average number of days spent in the hospital, the incidence of medical disputes and hospitalization expenses. The cesarean section rates for the study and control groups were 19.29% (401/2079) and 33.53% (753/2246), respectively (P < 0.05). The main indications for a cesarean section in the study group were arrest of the active phase of labor, fetal distress and intrapartum fever; the percentages of each indication were significantly different from those of the control group (P < 0.001). The rates of postpartum hemorrhage in the study group and control group were 7.74% (130/1678) and 8.1% (121/1493), respectively (P = 0.710). The incidence rates of severe perineal lacerations were 0.48% (8/1678) for the study group and 0.2% (3/1493) for the control group (P = 0.187). The rates of forceps use were 4.29% (72/1678) in the study group and 2.41% (36/1493) in the control group (P = 0.004). The incidence rate of fetal distress in the study group was 6.24% (169/2709) and 4.67% (105/2246) (P = 0.006) in the control group. No significant difference was observed in the incidence of neonatal asphyxia and pediatric interventions between the two groups (0.74% (20/2709) vs. 8.12% (220/2709) and 17 (0.76%) vs. 161 (7.17%), respectively). The average length of hospital stay was 4.74 ± 1.15 and 2.13 ± 1.23 days (P < 0.01). The incidence of medical disputes was significantly different between the two groups: 1.44% (30/2079) in the study group and 0.53% (12/2246) in the control group (P < 0.01). The hospitalization expenses were 5401.29 ± 296.33 yuan in the study group and 5253.53 ± 3655.79 yuan in the control group (P = 0.06). The implementation of the new labor protocol reduced the cesarean section rate without negatively impacting maternal and neonatal outcomes. In practice, bed turnover and the hospital utilization rate should be better controlled, patient-doctor communication should be strengthened and the quality of obstetrical service should be improved.

The purpose of this study was to determine how reduced plantar cutaneous sensation influences static postural control in individuals with and without CAI. A case-control study design. Twenty-six individuals with self-reported CAI and 26 matched healthy controls participated in this study. The plantar aspect of the participants' foot was then submersed in ice water (0°C) for 10min to reduce plantar sensation. Before and after the cooling procedure, plantar cutaneous sensation thresholds and single leg balance with eyes open and closed were assessed. Significantly, higher scores were observed in both groups after ice water submersion (p<0.001) indicating a significant reduction in the plantar cutaneous sensitivity after the cooling procedure. In single limb balance with eyes open, there were significant intervention main effects for the TTB ML mean (p<0.001), TTB AP mean (p=0.035) and TTB ML SD (p=0.021); indicating postural control improvement in both groups post-cooling. In single limb balance with eyes closed, Group×Intervention interactions were observed for the TTB AP mean (p=0.003) and TTB AP SD (p=0.017); indicating postural control deficits in CAI group post-cooling, but no changes in the control group. The main finding of this study was that reduced plantar cutaneous sensation induced by an ice submersion procedure caused eyes closed postural control impairments in those with CAI but not healthy controls. The present investigation demonstrated that the ability to dynamically reweight among sensory inputs to maintain postural stability appears to be diminished in CAI patients compared to healthy controls.

Decision making was assessed using a laboratory gambling task in 67 adults with the Human Immunodeficiency Virus (HIV+) and in 19 HIV-seronegative (HIV−) control participants. Neurocognitive test performance across several domains was also analyzed to examine potential cognitive mechanisms of gambling task performance. As predicted, the HIV+ group performed worse on the gambling task, indicating greater risky decision making. Specifically, the HIV+ group selected more cards from the “risky” or disadvantageous deck that included relatively large payoffs but infrequent large penalties. The control group also selected such risky cards but quickly learned to avoid them. Exploratory analyses also indicated that in the HIV+ group, but not in the control group, gambling task performance was correlated with Stroop Interference performance and long delay free recall on the California Verbal Learning Test, suggesting the role of inhibitory processes and verbal memory in the poorer gambling task performance in HIV. These findings indicate the usefulness of the gambling task as a laboratory tool to examine risky decision making and cognition in the HIV population. PMID:16719628

The aim of this study was to investigate the correlation between the natriuretic peptide precursor B (NPPB) gene single nucleotide polymorphism (SNP) c.-1298 G/T and pulse pressure (PP) of the Chinese Han population and the association between genotype and clinical indicators of hypertension. Peripheral blood was collected from 180 unrelated patients with hypertension and 540 healthy volunteers (control group), and DNA was extracted to amplify the 5'-flanking region and 2 exons of the NPPB gene by polymerase chain reaction; the fragment was sequenced after purification. The clinical data of all subjects were recorded, the distribution of the NPPB gene c.-1298 G/T polymorphism was determined, and differences in clinical indicators between the two groups were evaluated. The mean arterial pressure PP, and creatinine levels were significantly higher in the hypertension group than in the control group (P<0.05), but no other clinical indicators differed between the groups. There were no significant differences in genotype frequency and distribution of the NPPB gene c.-1298 G/T polymorphism between the hypertension group and the control group (P>0.05); in the control group, the mean PP of individuals with the SNP c.-1298 GG genotype was greater than that of individuals with the GT+TT genotype (P<0.05). In conclusion, there was no significant correlation between the NPPB gene c.-1298 G/T polymorphism and the incidence of essential hypertension in the Han population; however, the PP of the SNP c.-1298 GG genotype was greater than that of the GT+TT genotype in the control group.

To assess prospectively the effect of benchmarking on quality of primary care for patients with type 2 diabetes by using three major modifiable cardiovascular risk factors as critical quality indicators. Primary care physicians treating patients with type 2 diabetes in six European countries were randomized to give standard care (control group) or standard care with feedback benchmarked against other centers in each country (benchmarking group). In both groups, laboratory tests were performed every 4 months. The primary end point was the percentage of patients achieving preset targets of the critical quality indicators HbA1c, LDL cholesterol, and systolic blood pressure (SBP) after 12 months of follow-up. Of 4,027 patients enrolled, 3,996 patients were evaluable and 3,487 completed 12 months of follow-up. Primary end point of HbA1c target was achieved in the benchmarking group by 58.9 vs. 62.1% in the control group (P = 0.398) after 12 months; 40.0 vs. 30.1% patients met the SBP target (P < 0.001); 54.3 vs. 49.7% met the LDL cholesterol target (P = 0.006). Percentages of patients meeting all three targets increased during the study in both groups, with a statistically significant increase observed in the benchmarking group. The percentage of patients achieving all three targets at month 12 was significantly larger in the benchmarking group than in the control group (12.5 vs. 8.1%; P < 0.001). In this prospective, randomized, controlled study, benchmarking was shown to be an effective tool for increasing achievement of critical quality indicators and potentially reducing patient cardiovascular residual risk profile.

Radiation proctitis (RP) is inflammation and damage to the rectum, manifested secondary to ionizing radiation utilized for treatment. In this study, we evaluated the anti-inflammatory therapeutical and protective effects of ruscogenin in a model of acute RP. Thirty-two Sprague-Dawley rats were divided into 4 groups (n = 8) as sham, control, treatment, and prophylaxis groups. Prophylaxis group and treatment group were dosed ruscogenin by oral gavage for 14 days pre- and postradiation. At the end of the 28th day, all subjects were sacrificed. Histopathological analysis showed a significant increase in cryptitis abscess, cryptitis and reactive atypia, and depth of lymphocytic infiltration of the control group, compared to the other groups (P < 0.05), while treatment and prophylaxis groups showed significant decreases (P < 0.05). Immunohistochemical analysis indicated that immunoreactivity were significantly higher in control group (P < 0.05, P < 0.001, and P < 0.01, respectively), but vice versa for treatment and prophylaxis groups. There was not any significant difference for fibroblast growth factor 2 immunoreactivity. The epithelium of control rectums indicated an increase in TNF-α immunoreactivity while other groups had significant decrease (P < 0.01). Electron microscopical findings were parallel to light microscopy. In this study, ruscogenin was observed to be effective on prophylaxis or treatment of acute RP. Although there are various reports on the treatment of the rectum damaged by acute RP in the literature, this could be the first study since there is no research indicating the ultrastructural effect of ruscogenin.

Our first aim was to test whether a group cognitive-behavioral (CB) depression prevention program reduces substance use escalation over 2-year follow-up relative to two active comparison interventions and a brochure assessment control. Our second aim examined whether reductions in depressive symptoms mediate intervention effects, as posited by the affect-regulation model of substance use. In this indicated prevention trial, 341 high school adolescents at risk for depression because of the presence of elevated depressive symptoms were randomized to a Group CB intervention, group supportive-expressive group intervention, CB bibliotherapy, or educational brochure control condition. Participants in Group CB had significantly lower rates of substance use compared with brochure control participants at both 1- and 2-year follow-up and lower substance use at 2-year follow-up relative to bibliotherapy participants; no other condition differences were significant. Mediational analyses suggested that reductions in depressive symptoms from baseline to posttest accounted for changes in substance use over 2 years for participants in Group CB relative to brochure control participants but did not mediate effects relative to those receiving bibliotherapy. Results suggest that a secondary benefit of this CB group indicated depression prevention program is lower rates of long-term substance use. Findings supported the hypothesis that, relative to a nonactive comparison condition, reductions in depressive symptoms mediated the effects of Group CB prevention on substance use escalation.

The aim of this study was to assess the changes over time associated with salivary indices and the presence of Streptococcus mutans and Lactobacillus in patients treated with Occlus-o-Guide. Two groups of patients were evaluated: a test group of 20 patients treated with Occlus-o-Guide and a control group of 20 patients not subjected to orthodontic treatment. Both groups were homogeneous for age and sex. We examined the levels of S. Mutans and Lactobacillus, the salivary flow, the buffer capacity of saliva and the Sillness and Loe plaque index (PI). The samples were taken at baseline (T0), after 3 months (T1) and after 6 months of treatment (T2). All data were compared using Student's t test. The percentage of patients with a level of Streptococcus mutans able to cause caries was decreased in the test group (T0 = 10%, T1 = %, T2 = 0%) compared to the control group (T0 = 0%, T1 = 5%, T2 = 35%), whereas the amount of Lactobacilli was different (test group T0 = 15%, T1 = 0%, T2 = 10%; control group T0 = 0%, T1 = 5%, T2 = 35%). The total salivary flow was increased in the test group (T0 = 47, T1 = 61, T2 = 61) compared to the control group, in which it had remained almost constant (T0 = 44, T1 = 45, T2 = 45). The buffer capacity of saliva was unchanged in both groups over time; the sum of PI-plaque indices was reduced in the test group (T0 = 3, T1 = 0, T2 = 2) compared to the control group (T0 = 0, T1 = 14, T2 = 27). Despite the presence of the Occlus-o-Guide device, patients are able to maintain a good level of oral hygiene, showing improvements of the examinated parameters at follow-ups.

The aim of the current study was to evaluate the effect of pelvic floor muscle training in men with poststroke lower urinary tract symptoms. Thirty-one poststroke men, median age 68 years, were included in this single-blinded randomized controlled trial. Thirty participants, 15 in each group, completed the study. The intervention consisted of 3 months (12 weekly sessions) of pelvic floor muscle training in groups and home exercises. The effect was evaluated by the DAN-PSS-1 (Danish Prostate Symptom Score) questionnaire, a voiding diary, and digital anal palpation of the pelvic floor muscle. The DAN-PSS-1, symptom score indicated a statistical significant improvement ( p < .01) in the treatment group from pretest to posttest, but not in the control group. The DAN-PSS-1, total score improved statistically significantly in both groups from pretest to posttest (treatment group: p < .01; control group: p = .03). The median voiding frequency per 24 hours decreased from 11 at pretest to 7 (36%; p = .04) at posttest and to 8 (27%; p = .02) at follow-up in treatment group, although not statistical significantly more than the control group. The treatment group but not the control group improved statistically significantly in pelvic floor muscle function ( p < .01) and strength ( p < .01) from pretest to posttest and from pretest to follow-up ( p = .03; p < .01). Compared with the control group the pretest to posttest was significantly better in the treatment group ( p = .03). The results indicate that pelvic floor muscle training has an effect for lower urinary tract symptoms, although statistical significance was only seen for pelvic floor muscle.

This study assessed the effect of an educational intervention (interactive group discussion) on the prescribing behaviour of 51 general physicians from the north-west of Tabriz. Prescriptions were analysed pre-intervention and post-intervention (control and intervention groups) using a proforma with 8 indicators of correct prescribing. The mean number of drugs per prescription pre-intervention was 3.82. The percentage of prescriptions with antibiotics, corticosteroids and injections were 40.8%, 25.9% and 58.0%, respectively. Following the intervention there were slight but not significant changes in the indicators in both intervention and control groups compared with pre-intervention results.

The OPTIMISE study (NCT00681850) has been run in six European countries, including Luxembourg, to prospectively assess the effect of benchmarking on the quality of primary care in patients with type 2 diabetes, using major modifiable vascular risk factors as critical quality indicators. Primary care centers treating type 2 diabetic patients were randomized to give standard care (control group) or standard care with feedback benchmarked against other centers in each country (benchmarking group). Primary endpoint was percentage of patients in the benchmarking group achieving pre-set targets of the critical quality indicators: glycated hemoglobin (HbAlc), systolic blood pressure (SBP) and low-density lipoprotein (LDL) cholesterol after 12 months follow-up. In Luxembourg, in the benchmarking group, more patients achieved target for SBP (40.2% vs. 20%) and for LDL-cholesterol (50.4% vs. 44.2%). 12.9% of patients in the benchmarking group met all three targets compared with patients in the control group (8.3%). In this randomized, controlled study, benchmarking was shown to be an effective tool for improving critical quality indicator targets, which are the principal modifiable vascular risk factors in diabetes type 2.

Given the important role of treatment attendance as an indicator of program implementation and as a potential moderator of program effectiveness, this study sought to develop useful indicators of attendance for evidence-based practices. The current study examined consumer attendance patterns in a randomized controlled trial comparing illness management and recovery (n = 60) to a problem solving control condition (n = 58). Associations were examined between consumer clinical indicators, demographics, and level of recovery and indices of attendance. Attendance was poor, but comparable to rates found in many other studies. Four indicators of attendance (percent sessions attended, time enrolled, periods of attendance, and longest period of attendance) were highly inter-related and were more sensitive to baseline differences than a traditional approach of dichotomizing participants into “attenders” and “non-attenders.” Older age, lower hostility, fewer psychotic symptoms, and more education were associated with higher group attendance in both treatment conditions; the client-reported illness management and recovery scale was associated with attendance in the control group. Indicators of attendance were an advancement over dichotomous classification. Strategies to increase attendance are still needed, particularly for younger consumers with greater positive symptoms.

To analyze the polymorphism of HLA-A, B and DR alleles of Duchenne muscular dystrophy (DMD) patients in Han nationality of South China and to discuss the role of immune and genetic factors in the pathogenesis of DMD and muscular fiber necrosis. Polymerase chain reaction-reverse sequence specific oligonucleotide (PCR-RSSO) and National Marrow Donor Program (NMDP) were used to analyze the polymorphism of HLA-A,B and DR alleles of 113 DMD patients and 406 normal controls in Han nationality of South China. The frequencies of HLA-A24, A30 alleles in DMD group were 11.25% and 5.46% respectively, indicating notable difference (P=0.001, < 0.01) from 22.16% and 0.87% of control group; the frequencies of HLA-B13, B15, B61 and B62 alleles in DMD group were 12.26%, 16.92%, 0.44% and 0.44%, indicating a notable difference (P=0.016, < 0.01, 0.001) from 6.76%, 1.49%, 4.79% and 5.05% of control group; the frequencies of HLA-DR04, DR07, DR12 alleles in DMD group were 17.45%, 6.40% and 19.62%, indicating a notable difference (P=0.018, < 0.01, 0.012) from 10.67%, 2.24% and 11.92% of control group. There are significant differences in the HLA gene frequencies between DMD patients and normal controls. These results suggest that HLA genotype relates to the muscular necrosis and the pathogenesis of DMD.

We hypothesized that Theory of Planned Behavior (TPB) constructs (behavioral belief, attitude, subjective norm, perceived behavioral control, knowledge and behavioral intention) regarding preventive behaviors for obesity and type 2 diabetes will change favorably after completing the web-based intervention, HOT (Healthy Outcome for Teens) project, grounded in the TPB; and that passive online learning (POL) group will improve more than the active online learning (AOL) group. The secondary hypothesis was to determine to what extent constructs of the TPB predict intentions. 216 adolescents were recruited, 127 randomly allocated to the treatment group (AOL) and 89 to the control group (POL). The subjects completed a TPB questionnaire pre and post intervention. Both POL and AOL groups showed significant improvements from pretest to posttest survey. However, the results indicated no significant difference between POL and AOL for all constructs except behavioral belief. Correlational analysis indicated that all TPB constructs were significantly correlated with intentions for pretest and posttest for both groups. Attitude and behavioral control showed strongest correlations. Regression analysis indicated that TPB constructs were predictive of intentions and the predictive power improved post intervention. Behavioral control consistently predicted intentions for all categories and was the strongest predictor for pretest scores. For posttest scores, knowledge and attitude were the strongest predictors for POL and AOL groups respectively. Thus, HOT project improved knowledge and the TPB constructs scores for targeted behaviors, healthy eating and physical activity, for prevention of obesity and type 2 diabetes.

This study examined adaptive changes of eye-hand coordination during a visuomotor rotation task. Young adults made aiming movements to targets on a horizontal plane, while looking at the rotated feedback (cursor) of hand movements on a monitor. To vary the task difficulty, three rotation angles (30°, 75°, and 150°) were tested in three groups. All groups shortened hand movement time and trajectory length with practice. However, control strategies used were different among groups. The 30° group used proportionately more implicit adjustments of hand movements than other groups. The 75° group used more on-line feedback control, whereas the 150° group used explicit strategic adjustments. Regarding eye-hand coordination, timing of gaze shift to the target was gradually changed with practice from the late to early phase of hand movements in all groups, indicating an emerging gaze-anchoring behavior. Gaze locations prior to the gaze anchoring were also modified with practice from the cursor vicinity to an area between the starting position and the target. Reflecting various task difficulties, these changes occurred fastest in the 30° group, followed by the 75° group. The 150° group persisted in gazing at the cursor vicinity. These results suggest that the function of gaze control during visuomotor adaptation changes from a reactive control for exploring the relation between cursor and hand movements to a predictive control for guiding the hand to the task goal. That gaze-anchoring behavior emerged in all groups despite various control strategies indicates a generality of this adaptive pattern for eye-hand coordination in goal-directed actions.

To evaluate the effect of Supportan, an enteral nutrition (EN) specific for tumor patients, on the nutritional status and immune function of late-staged gastric cancer patients undergoing chemotherapy. Sixty-six late-staged gastric cancer patients undergoing chemotherapy were randomly divided into EN group (n=33) and control group (n=33). During chemotherapy, the patients in EN group received Supportan and the patients in the control group received basic diet. On the 14th day before chemotherapy and after chemotherapy, nutritional status and cell immune indicators were evaluated. As for nutrition indicators, there were no significant differences in EN group before and after chemotherapy (P > 0.05). Total protein, hemoglobin, prealbumin and transferrin significantly decreased after chemotherapy compared with those before chemotherapy in the control group (P< 0.01). The levels of CD4(+), CD8(+) T cells and CD4/CD8 were significantly increased, and NK cells, serum levels of IL-1, IL-6 were significantly decreased after chemotherapy in EN group (P< 0.01). The levels of IL-6 and TNF-alpha were significantly higher after chemotherapy than those before chemotherapy in the control group(P< 0.01). Curative effects of immune nutrition in EN group were superior to that in the control group, however, the differences were not statistically significant. The incidences of nausea, vomiting and marrow inhibition in Supportan group was lower compared with those in the control group, but with no significant difference. Supportan can prevent malnutrition of the late-staged gastric cancer patients undergoing chemotherapy, and improve immune function and alleviate adverse effects of chemotherapy.

This study assessed the visual profile of motor vehicle drivers in Owerri, Nigeria and to analyse the relationship between the various aspects of visual function in relation to road safety. A cross-sectional descriptive study of 150 commercial vehicles drivers and 130 private vehicles drivers was conducted between November 2005 and February 2006. Data were obtained using structured interviewer administered questionnaires and clinical examination was done. Standards procedures were used to determine visual indices. Data from the better eye (eye with a better visual acuity according to international and national standards) were reported, except in the analysis of near vision of the respondents. Twenty percent of the study group had normal visual acuity of ≥6/6 compared with 46.2% in the control group. The tonometric value in 88.0% and 93.1% of study and control groups respectively was less than 24mmHg. Both groups (96.8%) had normal confrontation visual field while 95.3% of study group and 97.7% of control group had normal colour vision. The most prevailing eye conditions that may reduce visual acuity were pterygium (51.3% in study group and 13.8% in the control group), retinopathy (16.7% of study group and 6.2% of control group) and glaucoma (12.0% and 6.9% of study and control groups respectively). Nineteen percent of the study group had regular eye examination compared with 38.5% in the control group. Alcohol consumption was 64.7% in the study group and 32.3% in the control group. Most of the commercial motor drivers in Owerri, Nigeria did not meet the Federal Road Safety Commission visual acuity standard for commercial motor drivers. Visual impairments and poor visibility are strongly associated with RTA among Nigerian motor vehicle drivers. Visual acuity and visual health care were poor among commercial motor drivers. There is need for renewed efforts to enforce a compulsory periodic visual examination for drivers, and to ensure that visual requirements for driving are met.

To validate the construct and discriminant properties of a hospital infection prevention and control program. The program consisted of four indicators: technical-operational structure; operational prevention and control guidelines; epidemiological surveillance system; and prevention and control activities. These indicators, with previously validated content, were applied to 50 healthcare institutions in the city of São Paulo, Southeastern Brazil, in 2009. Descriptive statistics were used to characterize the hospitals and indicator scores, and Cronbach's α coefficient was used to evaluate the internal consistency. The discriminant validity was analyzed by comparing indicator scores between groups of hospitals: with versus without quality certification. The construct validity analysis was based on exploratory factor analysis with a tetrachoric correlation matrix. The indicators for the technical-operational structure and epidemiological surveillance presented almost 100% conformity in the whole sample. The indicators for the operational prevention and control guidelines and the prevention and control activities presented internal consistency ranging from 0.67 to 0.80. The discriminant validity of these indicators indicated higher and statistically significant mean conformity scores among the group of institutions with healthcare certification or accreditation processes. In the construct validation, two dimensions were identified for the operational prevention and control guidelines: recommendations for preventing hospital infection and recommendations for standardizing prophylaxis procedures, with good correlation between the analysis units that formed the guidelines. The same was found for the prevention and control activities: interfaces with treatment units and support units were identified. Validation of the measurement properties of the hospital infection prevention and control program indicators made it possible to develop a tool for evaluating these programs in an ethical and scientific manner in order to obtain a quality diagnosis in this field.

Based on neurofeedback (NF) training as a neurocognitive treatment in attention-deficit/hyperactivity disorder (ADHD), we designed a randomized, controlled functional near-infrared spectroscopy (fNIRS) NF intervention embedded in an immersive virtual reality classroom in which participants learned to control overhead lighting with their dorsolateral prefrontal brain activation. We tested the efficacy of the intervention on healthy adults displaying high impulsivity as a sub-clinical population sharing common features with ADHD. Twenty participants, 10 in an experimental and 10 in a shoulder muscle-based electromyography control group, underwent eight training sessions across 2 weeks. Training was bookended by a pre- and post-test including go/no-go, n-back, and stop-signal tasks (SST). Results indicated a significant reduction in commission errors on the no-go task with a simultaneous increase in prefrontal oxygenated hemoglobin concentration for the experimental group, but not for the control group. Furthermore, the ability of the subjects to gain control over the feedback parameter correlated strongly with the reduction in commission errors for the experimental, but not for the control group, indicating the potential importance of learning feedback control in moderating behavioral outcomes. In addition, participants of the fNIRS group showed a reduction in reaction time variability on the SST. Results indicate a clear effect of our NF intervention in reducing impulsive behavior possibly via a strengthening of frontal lobe functioning. Virtual reality additions to conventional NF may be one way to improve the ecological validity and symptom-relevance of the training situation, hence positively affecting transfer of acquired skills to real life.

The present study was aimed at determining the role warm saline rinse in the prevention of alveolar osteitis following dental extractions. Apparently patients aged 16 and above who were referred to the Oral Surgery Clinic of our institution, with an indication for non-surgical extraction of pathologic teeth were prospectively and uniformly randomized into warm saline group and control. The experimental group (n = 80) were instructed to gargle 6 times daily with warm saline and no such instructions were given to the second group (n = 80) to serve as controls. Information on demographic, indications for extraction, and development of alveolar osteitis were obtained and analyzed. Comparative statistics were done using Pearson's chi square or Fisher's exact test as appropriate. A p value of less than 0.05 was considered significant. The demographic and other baseline parameters such as indications for extractions were comparable among the study groups (p > 0.05). The overall prevalence of alveolar osteitis was 13.7%. There was a statistical significant difference between the study groups with respect to development of alveolar osteitis (X2 = 15.00, df = 1, p = 0.001).The risk of development of alveolar osteitis was 4 times higher in the control group (OR = 4.33, P = 0.001). Warm saline mouth rinse instruction is beneficial in the prevention of development of alveolar osteitis after dental extractions.

Childhood obesity is a major public health concern but evidence-based approaches to tackle this epidemic sustainably are still lacking. The Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS (IDEFICS) study investigated the aetiology of childhood obesity and developed a primary prevention programme. Here, we report on the effects of the IDEFICS intervention on indicators of body fatness. The intervention modules addressed the community, school and parental level, focusing on diet, physical activity and stress-related lifestyle factors. A cohort of 16,228 children aged 2-9.9 years - about 2000 per country - was equally divided over intervention and control regions. (Participating countries were Sweden, Germany, Estonia, Hungary, Cyprus, Italy, Spain and Belgium.) We compared the prevalence of overweight/obesity and mean values of body mass index z-score, per cent body fat and waist-to-height ratio over 2 years of follow-up. Mixed models adjusting for age and socioeconomic status of the parents and with an additional random effect for country accounted for the clustered study design. The prevalence of overweight and obesity increased in both the intervention and control group from 18.0% at baseline to 22.9% at follow-up in the control group and from 19.0% to 23.6% in the intervention group. The difference in changes between control and intervention was not statistically significant. For the cohort as a whole, the changes in indicators of body fatness did not show any clinically relevant differences between the intervention and control groups. Changes in favour of intervention treatment in some indicators were counterbalanced by changes in favour of the control group in some other indicators. Over the 2-year-observation period, the IDEFICS primary prevention programme for childhood obesity has not been successful in reducing the prevalence of overweight and obesity nor in improving indicators of body fatness in the target population as a whole. © 2015 World Obesity.

Thalassemias are a heterogeneous group of genetic disorders characterized by hypochromic microcytic anemia that caused by deficient synthesis of one or more of globin subunits of human hemoglobin. This study has been conducted in the Northern part of Iraq among 238 subjects having β-thalassemia major (BTM). To evaluate their oral health status, dentofacial anomalies of patients who attended the Thalassemic center in Erbil city, were compared to 258 subjects of a control group according to the criteria suggested by the WHO in 1997, which is used to assess permanent teeth. Only 8.51% of the total study group demonstrated crowding of anterior teeth in one or both segments compared to the control group. Spacing in the incisal segments was higher, namely 19.23% in BTM compared to13.6% in the control group with a statistically significant difference (p<0.05). A higher percentage of both study and control groups were having an overbite grade (0.3-5.0 mm) of 49.59%, and 56.81%, respectively. It was found that the distal deviation from the normal anteroposterior molar relation in BTM was higher compared to the control group. Nearly similar percentages of patients were found to have an over jet grade(0.0-3.5 mm). Values of plaque and gingival health indices were recorded to be higher among the study group (plaque index = 1.570, ∓0.321 and gingival index = 1.205, ∓0.308). Differences were statistically highly significant for all indices (p<0.01). This may indicate that there is a negative attitude and poor dental knowledge of thalassemic subjects and their parents toward proper oral hygiene and dental health.

Infertility means failure to achieve pregnancy after one year of regular unprotected sexual intercourse. Infertile women may experience severe stress and depression. Numerous studies have indicated that auriculotherapy could reduce stress. Thus, the aim of the present study was to determine the effect of auriculotherapy on the stress and the outcome assisted reproductive technology in infertile women. The present study was a clinical trial that was conducted on 56 infertile women aged 20-45, who were assigned into two groups of intervention and control, from November 2014 to November 2015. The control group only received the routine treatments, while the intervention group, in addition to their routine treatment, received auriculotherapy for 8-10 sessions during menstrual cycle. Both groups completed Newton's Fertility Problem Inventory in three stages. The datasets collected for the study were analyzed using independent t -test, repeated-measures analysis of variance, and Chi-square test. The mean score of stress in the intervention group decreased significantly, compared to the control group prior to the embryo transfer and pregnancy test stages. Although insignificant, the rate of pregnancy in the intervention group was higher than the control group. There was a significant increase in the rate of clinical pregnancy in the intervention group, compared to the control. The results indicated that auriculotherapy might be effective in reducing stress and improving the outcome of assisted reproductive treatment.

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 two-part quasi-experimental repeated measures study examined whether computer simulated experiments have an effect on the problem solving skills of high school biology students in a school-within-a-school magnet program. Specifically, the study identified episodes in a simulation sequence where problem solving skills improved. In the Fall academic semester, experimental group students (n = 30) were exposed to two simulations: CaseIt! and EVOLVE!. Control group students participated in an internet research project and a paper Hardy-Weinberg activity. In the Spring academic semester, experimental group students were exposed to three simulations: Genetics Construction Kit, CaseIt! and EVOLVE! . Spring control group students participated in a Drosophila lab, an internet research project, and Advanced Placement lab 8. Results indicate that the Fall and Spring experimental groups experienced significant gains in scientific problem solving after the second simulation in the sequence. These gains were independent of the simulation sequence or the amount of time spent on the simulations. These gains were significantly greater than control group scores in the Fall. The Spring control group significantly outscored all other study groups on both pretest measures. Even so, the Spring experimental group problem solving performance caught up to the Spring control group performance after the third simulation. There were no significant differences between control and experimental groups on content achievement. Results indicate that CSE is as effective as traditional laboratories in promoting scientific problem solving and that CSE is a useful tool for improving students' scientific problem solving skills. Moreover, retention of problem solving skills is enhanced by utilizing more than one simulation.

To study the influence of leukodeplated blood transfusion on cellular immunity of patients with acute leuemia, so as to provide support for application of leuko-deplated blood transfusion in clinic. A total of 100 AL patients from January 2012 to December 2015 were chosen, and were divided into 2 groups: leukodeplated blood transfusion group(50 cases) and routine blood transfusion group(RBT) as control (50 cases). The effective rate, side effects, peripheral blood T cells and expression level of TLR2 and TLR4 were compared between 2 groups. The expression levels CD3(+), CD4(+), CD8(+), CD4(+)/CD8(+) of TLR2 and TLR4 in control group were (52.18±2.14)%, （27.28±1.19）%,（24.21±1.65）%,1.22±0.18,0.62±0.04 and 0.57±0.05, respectively, after treatment; while these indicators in LdBT group were （52.18±2.14）%,（30.97±2.01）%,（27.08±1.55）%,1.39±0.24,0.91±0.06 and 0.87±0.07, respectively, and above-mentioned indicators in LdBT group were significantly higher than those in control group（P<0.05）. Compared with these indicators before treatment, CD3(+), CD4(+), CD8(+) and CD4(+)/CD8(+) in the patients increased significantly（P<0.05）. The efficiency was 92.00% (46/50) in LdBT group, and 84.00% (42/50) in control group, without statistically significant difference（P>0.05）. The rate of side effects in study group was 6% (3/50), 18% (9/50) in control group, with statistically significance difference （P<0.05）. Leukodeplated blood transfusion can improve the cellular immunity of AL patients, and reduce the rate of side effects.

An online video assignment was developed to facilitate transition from the orientation session to the first contact with hospital patients for music therapy majors and other students enrolled in an Arts in Medicine service learning course (AIMS). All students (N = 84) completed a 2 hour hospital orientation session. After the orientation session the experimental group (n = 42) completed an online video assignment before volunteering at the hospital The control group (n = 42) began volunteering after the orientation session without completing the video assignment. Analysis indicates the majority of both groups initiated their first session independently without assistance from other AIMS volunteers, an experienced AIM volunteer, an AIM assistant, or hospital staff member. The majority of both groups also engaged at least one patient during their first visit at the hospital. Content analysis of "first contact" weekly reports, however, indicated experimental group students wrote longer reports and included more positive comments, particularly about patients, compared to control group students. Volunteers in the experimental group also began their contacts as scheduled on the course calendar compared to later starting dates of control group volunteers.

We developed a metabolomic method to evaluate the effect of pirfenidone on rats with acute paraquat (PQ) poisoning, through the analysis of various tissues (lung, liver, kidney, and heart), by gas chromatography-mass spectrometry (GC-MS). Thirty-eight rats were randomly divided into a control group, an acute PQ (20 mg kg -1 ) poisoning group, a pirfenidone (20 mg kg -1 ) treatment group, and a pirfenidone (40 mg kg -1 ) treatment group. Partial least squares-discriminate analysis (PLS-DA) revealed metabolic alterations in rat tissue samples from the two pirfenidone treatment groups after acute PQ poisoning. The PLS-DA 3D score chart showed that the rats in the acute PQ poisoning group were clearly distinguished from the rats in the control group. Also, the two pirfenidone treatment groups were distinguished from the acute PQ poisoning group and control group. Additionally, the pirfenidone (40 mg kg -1 ) treatment group was separated farther than the pirfenidone (20 mg kg -1 ) treatment group from the acute PQ poisoning group. Evaluation of the pathological changes in the rat tissues revealed that treatment with pirfenidone appeared to decrease pulmonary fibrosis in the acute PQ poisoning rats. The results indicate that pirfenidone induced beneficial metabolic alterations in the tissues of rats with acute PQ poisoning. Rats with acute PQ poisoning exhibited a certain reduction in biochemical indicators after treatment with pirfenidone, indicating that pirfenidone could protect liver and kidney function. Accordingly, the developed metabolomic approach proved to be useful to elucidate the effect of pirfenidone in rats of acute PQ poisoning.

Assessment of short-term practice of relaxation therapy on autonomic and cardiovascular functions in first-year medical students. Case-control, interventional study. Medical college laboratory. Sixty-seven medical students, divided into two groups: study group (n = 35) and control group (n = 32). Study group subjects practiced relaxation therapy (shavasana with a soothing background music) daily 1 hour for 6 weeks. Control group did not practice relaxation techniques. Cardiovascular parameters and spectral indices of heart rate variability (HRV) were recorded before and after the 6-week practice of relaxation therapy. The data between the groups and the data before and after practice of relaxation techniques were analyzed by one-way analysis of variance and Student t-test. In the study group, prediction of low-frequency to high-frequency ratio (LF-HF) of HRV, the marker of sympathovagal balance, to blood pressure (BP) status was assessed by logistic regression. In the study group, there was significant reduction in heart rate (p = .0001), systolic (p = .0010) and diastolic (p = .0021) pressure, and rate pressure product (p < .0001), and improvement in HRV indices, following 6 weeks of relaxation therapy. As determined by regression model, prediction of LF-HF to BP status was more significant (odds ratio, 2.7; p = .009) after practice of relaxation therapy. There was no significant alteration in these parameters in control subjects. Short-term practice of relaxation therapy can improve autonomic balance and promote cardiovascular health of medical students. Sympathovagal balance is directly linked to BP status in these individuals.

Pre-hypertension is considered as a cardiovascular disease predicator. Management of pre-hypertension is an appropriate objective for clinicians in a wide range of medical centers. Treatment of pre-hypertension is primarily non-pharmacological, one of which is massage therapy that is used to control the BP. This study aimed to evaluate the survival effect of Swedish massage (face, neck, shoulders, and chest) on BP of the women with pre-hypertension. This was a single-blind clinical trial study. Fifty pre-hypertensive women selected by simple random sampling which divided into control and test groups. The test group (25 patients) received Swedish massage 10-15 min, 3 times a week for 10 sessions and the control groups (25 patients) also were relaxed at the same environment with receiving no massage. Their BP was measured before and after each session and 72 h after finishing the massage therapy. Analyzing the data was done using descriptive and inferential statistical methods (Chi- square, Mann-Whitney, paired t-test and Student t-test) through SPSS software. The results indicated that mean systolic and diastolic BP in the massage group was significantly lower in comparison with the control group (P < 0.001). Evaluation of durability of the massage effects on BP also indicated that 72 h after finishing the study, still there was a significant difference between the test and control groups in systolic and diastolic BP (P < 0.001). Findings of the study indicated that massage therapy was a safe, effective, applicable and cost-effective intervention in controlling BP of the pre-hypertension women and it can be used in the health care centers and even at home.

Iron-deficiency anemia is the most prevalent nutritional deficiency worldwide. Iron-deficiency anemia has particular negative consequences on women in their childbearing years, and its prevention is a high priority in most health systems. This interventional study assessed the effect of nutrition education on hematologic indices, iron status, nutritional knowledge, and nutritional practices of high-school girls in Iran. Sixty healthy 16- to 18-year-old girls were randomly selected from two high schools in the city of Ahvaz and divided into two equally matched groups, one that received nutrition education, and one that did not. The education group received instruction in face-to-face sessions, group discussions, and pamphlets for 2 months. The control group did not receive any information during the study. Hematologic tests, corpuscular indices, and serum ferritin levels were measured at baseline and after 2 months. Food-frequency questionnaires were administered and histories taken, clinical signs of nutritional deficiencies observed, anthropometric measurements taken, nutritional knowledge tested, practices determined, and lifestyle questionnaires administered to all subjects. There were no statistically significant differences in any baseline characteristics between the two groups. Scores for nutritional knowledge and practices of the education group were significantly higher after two months compared with the baseline (31.4 +/- 6 vs. 24.3 +/- 5.9 points, p < .001, and 31.2 +/- 5 vs. 28.4 +/- 5.7 points, p < .05, respectively). The scores in the control group showed no significant changes from baseline to 2 months. Mean corpuscular volume values were elevated in the education group (p < .001) but not in the control group. However, in the control group, serum ferritin concentrations showed about a 17% drop at the end of the study (p < .004). There were no changes in other hematologic, lifestyle, clinical, or anthropometric data compared with baseline after completion of the study in both groups. These findings indicate that nutritional education can improve knowledge of healthy nutrition and lifestyle choices. Focused nutritional education using available resources and correcting current dietary habits in a vulnerable group of young women may result in dietary changes that can ultimately improve iron intake.

To compare the measurement of extra-vascular lung water (EVLW) by a single-indicator dilution technique and measurement obtained by gravimetry in different types of acute respiratory distress syndrome (ARDS). Thirty-three dogs were randomly assigned to three groups: control group, oleic acid group and hydrochloric acid group. ARDS was reproduced by either intravenous injection of oleic acid or intratracheal instillation of hydrochloric acid. EVLW was measured before ARDS, at the onset of ARDS and 10 hours after ARDS by a single indicator dilution technique. Ten hours after ARDS, dogs were sacrificed and then EVLW was quantitated by a gravimetric measurement (golden standard). Hemodynamics and pulmonary gas exchange were determined. There was a close positive correlation (r=0.8820, P<0.05) between single indicator dilution and gravimetric measurements. However, the measurement with the single indicator dilution was consistently higher than the gravimetric measurement. In the control group, there was a positive correlation (r=0.9870, P<0.05) between the values of EVLW as measured by single indicator dilution and by gravimetric measurements. In the oleic acid group, there was also a significant correlation (r=0.9360, P<0.05) between the values of EVLW as measured by single indicator dilution and by gravimetric measurements. In the hydrochloric acid group, correlation (r=0.7950, P<0.05) was also found between EVLW as measured by the two methods. However, the correlation found was lower in the hydrochloric acid group than those in other two groups. Hydrochloric acid instillation resulted in a significant increase in shunting and the partial pressure of carbon dioxide in artery (PaCO(2)) compared with oleic acid group at 10 hours after ARDS. The results of measuring EVLW using single indicator dilution measurement are closely related with those of gravimetric measurement in ARDS, however, the correlations varies with the methods of reproduction of ARDS.

To assess the effect of balance acupuncture for migraine without aura. Blind evaluation was conducted. Forty patients with migraine without aura were randomized into an observation group and a control group, 19 cases in each one with 1 patient dropped out respectively. In the observation group, Toutongxue , the middle point was used in the hollow before the 1, 2 metatarsal combination, and in the control group, a sham point was applied in the hollow before the 3, 4 metatarsal combination. The manipulation in the two groups was the same. The treatment was given for 4 weeks, once a day, 5 times a week. The comprehensive score and visual analogue scale (VAS) were used before and after treatment, as well as 4 weeks after treatment. The comprehensive score and VAS score after treatment in the observation group decreased after treatment (both P <0.05), of which the total headache time and attack number for one month were lower than those before treatment (both P <0.05), but at follow-up the VAS score was higher than that after treatment ( P <0.05). The above indices in the control group were not significantly different from those before treatment (all P >0.05). All the indices in the observation group after treatment and at follow-up were lower than those in the control group (all P <0.05). The different values for the comprehensive score and VAS score before and after treatment, before treatment and at follow-up in the observation group were better than those in the control group (all P <0.05). The different values after treatment and at follow-up had no significant difference between the two groups (both P >0.05). Balance acupuncture at Toutongxue achieves obvious effect for migraine without aura, which can relieve pain.

Lower urinary tract symptoms (LUTS) have a significant impact on quality of life (QoL) in post‑stroke patients. The aim of this study was to evaluate the effect of pelvic floor muscle training (PFMT) on QoL parameters in men with post‑stroke LUTS. Randomized, controlled and single‑blinded trial. Outpatients, University Hospital. Thirty‑one men, median age 68 (interquartile range 60-74) years, with post‑stroke LUTS were included. Thirty participants completed the study. The participants randomized to the treatment group were treated in a systematic, controlled and intensive PFMT program over 3 months (12 weekly sessions). The participants randomized to the control group did not receive specific LUTS treatment. The effect was measured on the 36-Item Short Form Health Survey (SF-36) and the Nocturia Quality‑of‑Life (N‑QoL) Questionnaire. The results on SF-36 indicated significant improvement within pre- and post‑test in the domains emotional role (median 77 to 100, P=0.03) and vitality (median 65 to 70, P=0.03) in the treatment group, but not the control group. There were no statistically significant differences between groups at pre‑test, post‑test or 6-month follow‑up. The results on N‑QoL indicated statistically significant differences between pre- and post‑test in the bother/concern domain in both groups and in sleep/energy for the control group, but not the treatment group. There were no statistically significant differences between groups. PFMT may improve the emotional health and vitality domains of QoL in men with mild to moderate post‑stroke and LUTS; however the improvements in the treatment group were not significantly better than for the control group. PFMT did not improve nocturia‑related QoL. This study is the first to evaluate the effect of PFMT on QoL parameters in men with mild to moderate post‑stroke and LUTS. The results indicate some short‑term effect on SF-36 but none on N‑QoL. However, further studies with larger sample sizes and with less restrictive inclusion and exclusion criteria are requested.

The goal of this study was to evaluate the protective and mitigative effect of vitamin C on oxidative stress in differentiated thyroid cancer (DTC) patients ablated with radioiodine. 58 DTC patients selected for radioactive iodine therapy (RAIT) with 5550 MBq 131 Iodine were divided into four groups. Group 1 (control group) consisted of patients who underwent RAIT routinely. Other patients received 1500 mg vitamin C daily 2 days after (group 2), 2 days before to 2 days after (group 3) and 2 days before RAIT (group 4). Serum oxidative stress markers including malondialdehyde (MDA), glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) were measured immediately before and 2 days after RAIT. A significant increase in MDA after RAIT was observed in all groups (p < 0.05). The concentrations of MDA were significantly higher in the control group compared to the intervention groups (p < 0.05). A significant decrease in the control group (p < 0.05) and increase in group 4 (p < 0.05) were observed in GSH level after RAIT (p < 0.05). Mean variation of GSH was significant between control group with groups 3 (p < 0.01) and 4 (p < 0.01). The results indicate that activity of SOD remained unchanged in all groups (p > 0.05). A significant increase was observed in CAT activity after RAIT in all groups (p < 0.05), which was higher in control group than intervention groups. In groups 3 (p < 0.05) and 4 (p < 0.05), this increase in CAT activity was significantly lower than the control group. RAIT causes serum oxidative stress, which can be ameliorated using vitamin C as an antioxidant. These results indicate that radioprotective effect of vitamin C is preferable to its mitigative effect.

Objective Evaluate the longterm effects of a brief group cognitive-behavioral (CB) adolescent depression indicated prevention program through 2-year follow-up, relative to CB bibliotherapy and brochure control, when high school personnel recruited students and delivered the program. Method 378 adolescents (M age = 15.5, SD = 1.2; 68% female, 72% White) with elevated self-assessed depressive symptoms who were randomized to CB group, CB bibliotherapy, or educational brochure control were assessed at pre, post, 6-, 12-, 18-, and 24-month follow-up. Results By 2 years post-intervention, CB group participants showed significantly lower major depressive disorder (MDD) onset versus CB bibliotherapy (10% vs. 25%, respectively; HR = 2.48, p = .006), but the incidence difference relative to brochure controls (17%) was nonsignificant; MDD incidence for bibliotherapy and brochure controls did not differ. Although CB group participants showed lower depressive symptoms at post versus brochure controls, there were no effects for this outcome or for social adjustment or substance use over 2-year follow-up. Moderator analyses suggested that participants with higher baseline depressive symptoms showed greater longterm symptom reductions in the CB group intervention versus bibliotherapy. Conclusions The evidence that a brief CB group intervention delivered by real-world providers significantly reduced MDD onset versus CB bibliotherapy is potentially encouraging. However, the lack of MDD prevention effects relative to brochure control and lack of longterm symptom effects (though consistent with results from other depression prevention trials), suggest that the delivery of CB group should be refined to strengthen its effectiveness.

The current study was designed to examine event-related brain potentials and autonomic responses to pictures indicating threat, relative to non-threat, and acoustic startle reflexes in traumatized youth diagnosed with PTSD, relative to non-exposed children, before and after receiving psychotherapy. Children in the control group were individually yoked and demographically matched to the PTSD group. Both groups displayed enhanced late positive potentials and more prolonged heart rate deceleration to pictures indicating threat, relative to non-threat, and larger skin conductance responses to pictures indicating threat, relative to non-threat, at time one. At time two, controls appeared to habituate, as reflected by an overall attenuated skin conductance response, whereas the PTSD group showed little change. Across time points the PTSD group exhibited greater acoustic startle reflexes than the control group. Psychotherapy and symptom reduction was not associated with electrophysiology. Drawing from the adult literature, this study was an attempt to address the scarcity of research examining electrophysiological irregularities in childhood PTSD. The overall results suggest that children and adolescents allocate more attention to threat-related stimuli regardless of PTSD status, and exaggerated startle and a possible failure to habituate skin conductance responses to threat-related stimuli in youth with versus without PTSD.

During recent decades, research in Iran in the area of the Quran and medical science has been seriously engaged in. With respect to the tendency toward spirituality and alternative medicine, we tried to find other aspects of the influence of the Quran. This study aimed to determine the effect of vocalizations of the Holy Quran with and without translation on the consequences of pregnancy (the prevalence of preterm delivery, caesarean delivery, and neonatal anthropometric indices) in women admitted to health care centers in Urmia, Iran. This was a three-armed parallel-group randomized clinical trial in which 168 pregnant women (25-28 weeks) in their first and second pregnancies were divided into three groups of 56 (Holy Quran with translation, Holy Quran without translation, and control group) by randomized blocking. The intervention was implemented once a week for three weeks in the health center, and on other days of the week, the participants listened at home to a CD they were given. The intervention and the control groups all received routine pregnancy care once a week. These mothers were tracked during their labor. Outcomes including gestational age at delivery, delivery type, and neonatal anthropometric indices were recorded based on the mother's records. There was no statistically significant difference between the groups in terms of demographic and obstetric characteristics before the intervention. In comparison with the control group, the probability of preterm delivery was lower in the Holy Quran with translation group (odds ratio: 0.3, CI 95%: 0.1-1.2) and in the Holy Quran without translation group (0.6, 0.2-1.9) as compared to the control group. However, this difference was not statistically significant. Similarly, the probability of caesarean delivery was lower in the Holy Quran with translation group (0.6, 0.3-1.4) and the Holy Quran without translation group (0.5, 0.2-1.2) as compared to the control group. Based on one-way ANOVA, there was no statistically significant difference between the study groups regarding the infants' anthropometric indices. Based on the results of this study, despite the lower prevalence of preterm labor and caesarean section in the intervention groups as compared to the control group, no statistically significant effect was seen. This was apparently due to the small sample size.

To investigate the myocardial protective effect of L-carnitine in children with hand, foot and mouth disease (HFMD) caused by Coxsackie A16 virus and possible mechanisms. A total of 60 HFMD children with abnormal myocardial enzyme after Coxsackie A16 virus infection were enrolled and randomly divided into L-carnitine group and fructose-1,6-diphosphate group (fructose group), with 30 children in each group. The two groups were given L-carnitine or fructose diphosphate in addition to antiviral and heat clearance treatment. Another 30 healthy children who underwent physical examination were enrolled as control group. The changes in myocardial zymogram, malondialdehyde (MDA), superoxide dismutase (SOD), and apoptosis factors sFas and sFasL after treatment were compared between groups. There was no significant difference in treatment response between the L-carnitine group and the fructose group (P>0.05). One child in the fructose group progressed to critical HFMD, which was not observed in the L-carnitine group. Before treatment, the L-carnitine group and the fructose group had significantly higher indices of myocardial zymogram and levels of MDA, sFas, and sFasL and a significantly lower level of SOD than the control group (P<0.05), while there were no significant differences in these indices between the L-carnitine group and the fructose group (P>0.05). After treatment, the L-carnitine group and the fructose group had significant reductions in the indices of myocardial zymogram and levels of MDA, sFas, and sFasL and a significant increase in the level of SOD (P<0.05); the fructose group had a significantly higher level of creatine kinase (CK) than the control group and the L-carnitine group, and there were no significant differences in other myocardial enzyme indices, MDA, sFas, and sFasL between the L-carnitine group and the fructose group, as well as between the L-carnitine and fructose groups and the control group (P>0.05). SOD level was negatively correlated with aspartate aminotransferase, lactate dehydrogenase (LDH), CK, and creatine kinase-MB (CK-MB) (r=-0.437, -0.364, -0.397, and -0.519 respectively; P<0.05), and MDA level was positively correlated with LDH and CK-MB (r=0.382 and 0.411 respectively; P<0.05). L-carnitine exerts a good myocardial protective effect in children with HFMD caused by Coxsackie A16 virus, possibly by clearing oxygen radicals and inhibiting cardiomyocyte apoptosis.

Certain factors in mothers could be risk indicators for certain diseases in their children. Hence, this study was undertaken to assess maternal risk indicators for the development of early childhood caries in their children. A comparative, cross-sectional study was designed among 180 mother-child pairs attending various Anganwadi centers. Demographic, dietary, oral hygiene practices and other necessary information were collected from mothers using a structured questionnaire. Caries status and amount of plaque were recorded through clinical examination. Nonstimulated saliva from mothers was cultured for mutans streptococci (MS). Data were analyzed using SPSS version 17. Chi-square, Student's t-test, and logistic regression were used. A P ≤ 0.05 was considered statistically significant. In the study group, 73.3% of mothers had caries as compared to only 53.3% mothers in control group. While mean DMFT and mean DMFS of mothers in the study group was 3.78 ± 3.91 and 8.37 ± 12.2, respectively, the same for the mothers in the control group was 2.66 ± 3.01 and 5.8 ± 5.3. Sixty (66.7%) out of ninety mothers in the study group had a high MS count as compared to only 40 (44.4%) mothers in control group (P = 0.003). The present study showed that high salivary MS count and decay in mothers could be important risk indicators for the development of caries in their children.

OBJECTIVE To assess prospectively the effect of benchmarking on quality of primary care for patients with type 2 diabetes by using three major modifiable cardiovascular risk factors as critical quality indicators. RESEARCH DESIGN AND METHODS Primary care physicians treating patients with type 2 diabetes in six European countries were randomized to give standard care (control group) or standard care with feedback benchmarked against other centers in each country (benchmarking group). In both groups, laboratory tests were performed every 4 months. The primary end point was the percentage of patients achieving preset targets of the critical quality indicators HbA1c, LDL cholesterol, and systolic blood pressure (SBP) after 12 months of follow-up. RESULTS Of 4,027 patients enrolled, 3,996 patients were evaluable and 3,487 completed 12 months of follow-up. Primary end point of HbA1c target was achieved in the benchmarking group by 58.9 vs. 62.1% in the control group (P = 0.398) after 12 months; 40.0 vs. 30.1% patients met the SBP target (P < 0.001); 54.3 vs. 49.7% met the LDL cholesterol target (P = 0.006). Percentages of patients meeting all three targets increased during the study in both groups, with a statistically significant increase observed in the benchmarking group. The percentage of patients achieving all three targets at month 12 was significantly larger in the benchmarking group than in the control group (12.5 vs. 8.1%; P < 0.001). CONCLUSIONS In this prospective, randomized, controlled study, benchmarking was shown to be an effective tool for increasing achievement of critical quality indicators and potentially reducing patient cardiovascular residual risk profile.

Aims: This study compared the psychometric properties of two self-efficacy instruments related to physical activity. Factorial validity, cross-group and longitudinal invariance, and composite reliability were examined. Methods: Secondary analysis was conducted on data from a group randomized controlled trial investigating the effect of a 17-week intervention on increasing moderate to vigorous physical activity among 5th–8th grade girls (N = 1,012). Participants completed a 6-item Physical Activity Self-Efficacy Scale (PASE) and a 7-item Self-Efficacy for Exercise Behaviors Scale (SEEB) at baseline and post-intervention. Confirmatory factor analyses for intervention and control groups were conducted with Mplus Version 7.4 using robust weighted least squares estimation. Model fit was evaluated with the chi-square index, comparative fit index, and root mean square error of approximation. Composite reliability for latent factors with ordinal indicators was computed from Mplus output using SAS 9.3. Results: Mean age of the girls was 12.2 years (SD = 0.96). One-third of the girls were obese. Girls represented a diverse sample with over 50% indicating black race and an additional 19% identifying as mixed or other race. Both instruments demonstrated configural invariance for simultaneous analysis of cross-group and longitudinal invariance based on alternative fit indices. However, simultaneous metric invariance was not met for the PASE or the SEEB instruments. Partial metric invariance for the simultaneous analysis was achieved for the PASE with one factor loading identified as non-invariant. Partial metric invariance was not met for the SEEB. Longitudinal scalar invariance was achieved for both instruments in the control group but not the intervention group. Composite reliability for the PASE ranged from 0.772 to 0.842. Reliability for the SEEB ranged from 0.719 to 0.800 indicating higher reliability for the PASE. Reliability was more stable over time in the control group for both instruments. Conclusions: Results suggest that the intervention influenced how girls responded to indicator items. Neither of the instruments achieved simultaneous metric invariance making it difficult to assess mean differences in PA self-efficacy between groups. PMID:28824487

Based on neurofeedback (NF) training as a neurocognitive treatment in attention-deficit/hyperactivity disorder (ADHD), we designed a randomized, controlled functional near-infrared spectroscopy (fNIRS) NF intervention embedded in an immersive virtual reality classroom in which participants learned to control overhead lighting with their dorsolateral prefrontal brain activation. We tested the efficacy of the intervention on healthy adults displaying high impulsivity as a sub-clinical population sharing common features with ADHD. Twenty participants, 10 in an experimental and 10 in a shoulder muscle-based electromyography control group, underwent eight training sessions across 2 weeks. Training was bookended by a pre- and post-test including go/no-go, n-back, and stop-signal tasks (SST). Results indicated a significant reduction in commission errors on the no-go task with a simultaneous increase in prefrontal oxygenated hemoglobin concentration for the experimental group, but not for the control group. Furthermore, the ability of the subjects to gain control over the feedback parameter correlated strongly with the reduction in commission errors for the experimental, but not for the control group, indicating the potential importance of learning feedback control in moderating behavioral outcomes. In addition, participants of the fNIRS group showed a reduction in reaction time variability on the SST. Results indicate a clear effect of our NF intervention in reducing impulsive behavior possibly via a strengthening of frontal lobe functioning. Virtual reality additions to conventional NF may be one way to improve the ecological validity and symptom-relevance of the training situation, hence positively affecting transfer of acquired skills to real life.

Creole-like cattle blood types were compared with a mixed control group and Longhorn data using hemolytic and electrophoretic techniques. Among the hemolytic tests, the crucial B system analyses indicated that 1) the Creole-like animals were more similar to Longhorns than were the controls; 2) the three groups were different from each other; 3) the three groups were not mutually exclusive. Eleven new phenogroups were postulated. The remaining blood group systems and the electrophoretic tests raised interesting biohistorical questions but were generally less useful in discriminating among the three groups of cattle.

A randomized controlled trial of qigong for fibromyalgia

PubMed Central

2012-01-01

Introduction Fibromyalgia is difficult to treat and requires the use of multiple approaches. This study is a randomized controlled trial of qigong compared with a wait-list control group in fibromyalgia. Methods One hundred participants were randomly assigned to immediate or delayed practice groups, with the delayed group receiving training at the end of the control period. Qigong training (level 1 Chaoyi Fanhuan Qigong, CFQ), given over three half-days, was followed by weekly review/practice sessions for eight weeks; participants were also asked to practice at home for 45 to 60 minutes per day for this interval. Outcomes were pain, impact, sleep, physical function and mental function, and these were recorded at baseline, eight weeks, four months and six months. Immediate and delayed practice groups were analyzed individually compared to the control group, and as a combination group. Results In both the immediate and delayed treatment groups, CFQ demonstrated significant improvements in pain, impact, sleep, physical function and mental function when compared to the wait-list/usual care control group at eight weeks, with benefits extending beyond this time. Analysis of combined data indicated significant changes for all measures at all times for six months, with only one exception. Post-hoc analysis based on self-reported practice times indicated greater benefit with the per protocol group compared to minimal practice. Conclusions This study demonstrates that CFQ, a particular form of qigong, provides long-term benefits in several core domains in fibromyalgia. CFQ may be a useful adjuvant self-care treatment for fibromyalgia. Trial registration clinicaltrials.gov NCT00938834. PMID:22863206

With the increasing incidence of periodontal diseases and development of antibiotic resistance, the global need for alternative treatment modalities, safe, effective, and economical products is the need of time. Aloe vera is a medicinal plant which has the greater medicinal value and enormous properties for curing and preventing oral diseases disease. The aim of the study was to access the effect of Aloe vera mouthwash on the dental plaque and gingivitis and comparing it with the bench mark control chlorhexidine and placebo. 345 healthy subjects were randomly allocated in 3 groups to the test group (n=115) - mouthwash containing Aloe vera, Control group (n=115) -chlorhexidene group, Distilled water - Placebo (n=115) . Plaque Index (PI) and Gingival Index (GI) were assessed at days 0, 15 and 30. Subjects were asked to rinse their mouth with the stated mouthwash, twice a day, during a 30-day period. Our result showed that Aloe vera mouthrinse is equally effective in reducing periodontal indices as Chlorhexidine. The results demonstrated a significant reduction of gingival bleeding and plaque indices in both groups over a period of 15 and 30 days as compared to placebo group. There was a significant reduction on plaque and gingivitis in Aloe vera and chlorhexidine groups and no statistically significant difference was observed among them (p>0.05). Aloe vera mouthwash showed no side effects as seen with chlorhexidine. The results of the present study indicate that Aloe vera may prove to be an effective mouthwash owing to its ability in reducing periodontal indices.

Five different East Coast fever (ECF)-control strategies (involving ECF immunisation by the infection-and-treatment method) were tested in groups of traditionally managed Sanga cattle in the Central Province of Zambia over a period of 2.5 years. Two groups were under intensive tick control (weekly spraying with acaricide)--one group immunised and the other non-immunised. Two groups were under no tick control--one group immunised and the other non-immunised. The fifth group was under seasonal tick control (18 sprays/year) and was immunised against ECF. The input and output data were used to construct discounted cash flows for each group. The seasonally sprayed and immunised group gave the highest net present value, and the non-immunised group with no tick control, the lowest. A break-even analysis showed that the immunisation costs could rise to US$25.9 per animal before profitability was affected. For herds under intensive tick control, immunisation was of no financial benefit. The results demonstrate the value of immunisation, and indicate the importance of its combination with seasonal tick-control measures.

To assess the effects of a 50% discount on low-energy density (ED) fruits and vegetables (F&V), bottled water, and diet sodas on shoppers' purchasing, food intake, and body weight. A randomized, controlled trial was conducted at two Manhattan supermarkets, in which a 4-week baseline period (no discounts) preceded an 8-week intervention period (50% discount), and a 4-week follow-up period (no discounts). Twenty-four hour dietary recall, as well as body weight and body composition measures were obtained every 4 weeks. Participants (n = 47, 33f; 14m) were overweight and obese (BMI ≥ 25) shoppers. Purchasing of F&V during intervention was greater in the discount group than in the control group (P < 0.0001). Purchasing of these items by the discount group relative to the control group during follow-up was reduced from intervention (P = 0.002), but still remained higher than during baseline (P = 0.01), indicating a partially sustained effect. Intake of F&V increased from baseline to intervention in the discount group relative to the control group (P = 0.037) and was sustained during follow-up. Body weight change did not differ significantly between groups, although post hoc analysis indicated a change within the discount group (-1.1 kg, P = 0.006) but not within the control group. Discounts of low-ED F&V led to increased purchasing and intake of those foods. Copyright © 2013 The Obesity Society.

The incidence of congenital hypothyroidism (CH) in newborn infants ranges from 1 in 3,000 to 1 in 4,000. Previous studies have indicated the neuroprotective role of microRNA (miR)-124-3p, however the expression and role of miR-124-3p in CH remain unclear. Therefore, the present study was performed to investigate the role and precise molecular mechanism of miR-124-3p in CH. Propylthiouracil (50 mg/day) was injected into the stomach of pregnant rats from gestational day 15 until parturition in order to establish a thyroid hypofunction model. Newborn rats were divided into the following four groups: The control group; the thyroid hypofunction group; the miR-124-3p mimic group; and the miR-124-3p negative control group. Reverse transcription-quantitative polymerase chain reaction indicated that miR-124-3p was significantly decreased in the hippocampus of the thyroid hypofunction group compared with the control group. Bioinformatics software was used to predict mRNA targets recognized by miR-124-3p and the programmed cell death protein 6 (PDCD6) 3' untranslated region (UTR) was demonstrated to exhibit the seed sequence of miR-124-3p. The interaction between miRNA-124-3p and PDCD6 was then verified using a dual-luciferase reporter assay system. PDCD6 expression was significantly increased in the hippocampus of rats with CH compared with the control group. Flow cytometry was performed to investigate the effects of miR-124-3p on neuronal cell apoptosis and the results indicated that the apoptosis rate in the thyroid hypofunction group was significantly increased compared with the control group; this increase was reversed by transfection with miR-124-3p mimics. Western blot analysis was used to detect the levels of cleaved poly [ADP-ribose] polymerase (PARP), full-length PARP, caspase-3, B cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax) proteins. The results indicated that the expression of cleaved PARP, caspase-3 and Bax protein were significantly increased and the expression of full-length PARP and Bcl-2 protein was significantly decreased compared with the control group. These effects were reversed by miRNA-124-3p mimic transfection. Taken together, the results of the present study demonstrate that miRNA-124-3p serves a protective role in CH via targeting PDCD6.

Although hemostatic agents may be effective at stopping hemorrhage, they may fail because of hemodilution from intravenous fluids. The purpose of this study was to investigate the effects of QuikClot Combat Gauze (QCG) on rebleeding in a class II hemorrhage in the presence of hemodilution in a lethal femoral injury. This was a prospective experimental, between swine subjects design. Pigs were assigned to one of two groups: QCG (n=15) or control (n=15). Thirty percent of the pig's blood was exsanguinated and then a 3:1 ratio of ringers lactate was administered. A groin injury was created by transecting the femoral artery and vein to simulate a battlefield injury and allowed to bleed for one minute. After one minute of hemorrhage, proximal pressure was applied to the injury, and QCG was placed into the wound followed by standard wound packing. The control group underwent the same procedures with the exception of the hemostatic agent. For both groups, 5 minutes of direct pressure was applied to the wound followed by a standard pressure dressing. Dressings were removed after 30 minutes, and the amount of hemorrhage was calculated in milliliters for each group for a period of 5 minutes. An activated clotting time was used to exclude any pigs with coagulation pathology. A multivariate analysis of variance indicated that there were no significant differences in the groups relative to weight, amount of one minute hemorrhage, fluid deficit replacement, blood volume, and the activated clotting time (P>.05) indicating that the groups were equivalent on these parameters. A t test indicated that there was significantly less bleeding (P=.002) in the QCG group (36 mL±112 mL) compared to the control group (340 mL±297 ml). QCG produces a robust clot that can more effectively tolerate hemodilution compared to a control group.

Converging findings from recent research suggest a functional relationship between attention-deficit/hyperactivity disorder (ADHD)-related hyperactivity and demands on working memory (WM) in both children and adults. Excessive motor activity such as restlessness and fidgeting are not pathognomonic symptoms of ADHD, however, and are often associated with other diagnoses such as generalized anxiety disorder (GAD). Further, previous research indicates that anticipatory processing associated with anxiety can directly interfere with storage and rehearsal processes of WM. The topographical similarity of excessive motor activity seen in both ADHD and anxiety disorders, as well as similar WM deficits, may indicate a common relationship between WM deficits and increased motor activity. The relationship between objectively measured motor activity (actigraphy) and PH and visuospatial WM demands in adults with ADHD (n = 21), adults with GAD (n = 21), and healthy control adults (n = 20) was examined. Although all groups exhibited significant increases in activity from control to WM conditions, the ADHD group exhibited a disproportionate increase in activity, while activity exhibited by the GAD and healthy control groups was not different. Findings indicate that ADHD-related hyperactivity is uniquely related to WM demands, and appear to suggest that adults with GAD are no more active relative to healthy control adults during a cognitively demanding laboratory task.

Numerous studies have shown an association between patent foramen ovale (PFO) and cryptogenic stroke suggesting that paradoxical emboli may be an important cause of stroke. In addition, some authors have proposed that platelet activation is present in PFO patients and this might be the cause of the stroke. The aim of this study was to assess the mean platelet volume (MPV), an indicator of platelet activation and/or reactivity in patients with PFO. The study group consisted of 77 patients with PFO. An age, sex, BMI-matched control group was composed of 43 healthy volunteers. We measured serum MPV values in patients and controls. MPV was significantly higher among PFO patients when compared with control group (9.0±0.8 vs. 8.3±0.9 fl, respectively; P<0.001). We have shown that MPV was significantly elevated in patients with PFO compared with controls.

The cancer-preventive activity of an extract of Withania somnifera (WS) roots was examined in female transgenic (MMTV/Neu) mice that received a diet containing the extract (750 mg/kg of diet) for 10 months. Mice in the treated group (N=35) had an average of 1.66 mammary carcinomas, and mice in the control group (N=33) had 2.48, a reduction of 33%. The average weights of the carcinomas were 2.36 g for mice in the treated group and 2.63 g for the controls, a difference of 10%. Labeling indices for Ki67 and proliferating cell nuclear antigen marker in mammary carcinomas of the treated group were 35% and 30% lower, respectively, than those of the corresponding control group. Expression of the chemokine was reduced by 50%. These results indicate that the root extract reduced the number of mammary carcinomas that developed and reduced the rate of cell division in the carcinomas. PMID:25368231

The determination of total IgE in tears is useful as a diagnostic tool in allergic conjunctivitis disease (ACD). We evaluated the efficacy of this diagnostic tool for ACD, which is a clinically applicable novel immunochromagraphic method to determine total IgE in tears. The subjects comprised 4 groups: 15 patients with vernal keratoconjunctivitis (VKC group), 8 patients with atopic keratoconjunctivitis (AKC group), 18 patients with allergic conjunctivitis (AC group), and 7 normal healthy volunteers as a control (control group). Tears were sampled using filter paper, and the total IgE in tears was determined by immunochromatography assay. Semiquantitative determination was carried out by examining the intensity of the colored line using an immunochromatoreader (IgE index). The relationship between IgE indices in tears and total IgE levels in serum or between IgE indices and the clinical scores of ACD was examined. The positive ratio obtained by this novel application of the immunochromatography assay was 38 of the 41 in the patients with ACD and none in the 7 controls. IgE indices for the VKC group, AKC group and AC group were 27.5 +/- 15.6, 19.8 +/- 15.8, and 4.0 +/- 3.1 (mean +/- SD), respectively. IgE indices in tears showed significant correlation with both total IgE levels in serum (P < 0.001, r = 0.76) and clinical scores of ACD (P < 0.001, r = 0.57). The novel application of the immunochromatography assay to assess the total IgE in tears is a useful clinical tool to investigate ACD.

We tested whether a brief cognitive behavioral (CB) group and bibliotherapy prevention reduce major depressive disorder (MDD) onset, depressive symptoms, and secondary outcomes relative to brochure controls in adolescents with self-reported depressive symptoms when school personnel recruit participants and deliver the intervention. Three hundred seventy-eight adolescents (M age = 15.5 years, SD = 1.2; 68% female, 72% White) with elevated self-assessed depressive symptoms were randomized to a 6-session CB group, minimal contact CB bibliotherapy, or educational brochure control. Participants were assessed at pretest, posttest, and 6-month follow-up. CB group participants showed a significantly lower risk for major depressive disorder onset (0.8%), compared to both CB bibliotherapy (6.3%) and brochure control (6.5%; hazard ratio = 8.1 and 8.3, respectively). Planned contrasts indicated that CB group resulted in lower depressive symptom severity than brochure control at posttest (p = .03, d = 0.29) but not 6-month follow-up; differences between CB group and bibliotherapy were nonsignificant at posttest and 6-month follow-up. Condition effects were nonsignificant for social adjustment and substance use. The finding that a brief CB group intervention delivered by real-world providers significantly reduced MDD onset relative to both brochure control and bibliotherapy is very encouraging, although effects on continuous outcome measures were small or nonsignificant and approximately half the magnitude of those found in efficacy research, potentially because the present sample reported lower initial depression.

The aim of the present study was to investigate the protective effects of yak-activated protein on hematopoiesis and cytokine function in radiation-induced injury in mice. A total of 180 Kunming mice were randomly divided into three groups (A, B and C). Of these, 60 were randomly divided into a normal control group, a radiation model group, a positive control group and 3 yak-activated protein groups (high, medium and low dose groups; 10, 5 and 2.5 mg/kg, respectively). The other 120 mice were used for the subsequent experiments on days 7 and 14 following radiation. Yak-activated protein was administered orally to mice in the treatment groups and an equal volume of saline was administered orally to mice in the normal control and radiation model groups for 14 days. The positive control group received amifostine (150 mg/kg) via intraperitoneal injection. With the exception of the control group, the groups of mice received a 5 Gy quantity of X-radiation evenly over their whole body once. Changes in the peripheral hemogram, thymus and spleen indices, DNA content in the bone marrow, interleukin (IL)-2 and IL-6 levels, and the expression levels of B cell lymphoma 2 (Bcl-2) and Bcl-2-associated X protein (Bax) following irradiation were assessed. The low dose of yak-activated protein significantly increased Spleen indices in mice 14 days after irradiation and the high and middle dose of yak-activated protein significantly increased Thymus indices in mice 14 days after irradiation (P<0.05) compared with the control group. In addition, hemogram results increased gradually in the low-yak-activated protein dose group and were significantly higher 7 days after irradiation compared with the radiation model group (P<0.05). The DNA content in the bone marrow was markedly increased in the yak-activated protein groups, and increased significantly in the low dose group at 7 days post-irradiation compared with the radiation model group (P<0.05). The IL-2 content was significantly increased in the yak-activated protein groups (P<0.05). Furthermore, Bcl-2 expression was increased and Bax expression was decreased (P<0.05). These results suggest that yak-activated protein exerts protective effects against radiation-induced injury in mice. The optimal effects of yak-activated protein were observed in the medium dose group 14 days after irradiation.

Charlton, Samuel G; Starkey, Nicola J; Malhotra, Neha

2018-08-01

The potential for using road markings to indicate speed limits was investigated in a driving simulator over the course of two sessions. Two types of experimental road markings, an "Attentional" set designed to provide visually distinct cues to indicate speed limits of 60, 80 and 100 km/h, and a "Perceptual" set designed to also affect drivers' perception of speed, were compared to a standard undifferentiated set of markings. Participants (n = 20 per group) were assigned to one of four experimental groups (Attentional-Explicit, Attentional-Implicit, Perceptual-Explicit, Perceptual-Implicit) or a Control group (n = 22; standard road markings). The Explicit groups were instructed about the meaning of the road markings while those in the Implicit and Control groups did not receive any explanation. Participants drove five 10 km simulated roads containing three speed zones (60, 80 and 100 km/h) during the first session. The participants returned to the laboratory approximately 3 days later to drive five more trials including roads they had not seen before, a trial that included a secondary task, and a trial where speed signs were removed and only markings were present. The findings indicated that both types of road markings improved drivers' compliance with speed limits compared to the control group, but that explicit instruction as to the meaning of the markings was needed to realise their full benefit. Although previous research has indicated the benefit of road markings used as warnings to indicate speed reductions in advance of horizontal or vertical curves, the findings of the present experiment also suggest that systematically associating road markings with specific speed limits may be a useful way to improve speed limit compliance and increase speed homogeneity.

The purpose of this study was to investigate the interaction of caries risk indicators and metabolic control in children with type 1 diabetes mellitus. The study included 50 children with type 1 DM and 50 healthy controls, all 6 to 9 years old. Diabetic children were classified into 3 groups: well, fairly, and poorly controlled based on glycosilated hemoglobin level. Personal, family data, medical and dental history were collected. Children were examined for caries experience, plaque, and gingival condition. Saliva samples were obtained for culturing mutans streptococci, lactobacilli, and Candida, and colony forming units were counted. No significant differences existed between all groups regarding caries experience or mean log count of micro-organisms. Diabetic children differed significantly from healthy children in parental occupation and education, dental visits, oral hygiene, and plaque and gingival indices, whereas no differences were observed among children with different levels of metabolic control regarding these factors. Regression analysis identified mutans streptococci as a significant variable affecting caries experience in diabetic children. Regarding the interaction of caries risk indicators and metabolic control on caries experience in diabetic children, the only variable that showed a significant effect was mutans streptococci.

Introduction Multiple sclerosis (MS) as a chronic disease could affect patients’ various domains of life. Aim This study was conducted to study the effect of yoga on the physiological indices, anxiety and social functioning of patients with MS in southwest, Iran. Materials and Methods In this clinical trial study, 60 MS patients were enrolled according to inclusion criteria and randomly assigned to two groups of 30 each. Prior to and after intervention, the patients’ vital signs were measured. For case group yoga exercises were performed three sessions a week for 12 weeks while control group performed no exercise. The data were gathered by questionnaire and analysed by descriptive and analytical statistics in SPSS. Results Prior to intervention, there was no significant difference in fatigue severity and pain between the two groups but the mean fatigue severity and pain in case group decreased compared to the control group after the intervention. Prior to intervention, there was no significant difference in mean physiological indices between the two groups but the mean physiological indices in case group decreased significantly after the intervention (p<0.05). Conclusion Yoga is likely to increase self-efficacy of MS patients through enhancing physical activity, increasing the strength of lower limbs and balance, and decreasing fatigue and pain, and finally to promote social functioning and to relieve stress and anxiety in these patients.

With regard to the global childhood obesity epidemic, it is imperative that effective lifestyle interventions are devised to combat childhood obesity. This paper describes the development and implementation of a comprehensive (a combination of diet and physical activity (PA)), social cognitive behaviour modification intervention using accelerometry and a dietary diary to tackle child overweight and obesity. The comprehensive intervention effect was evaluated in a comparison with diet only, PA only and a no-treatment control group. A pilot study was conducted with a non-randomized cluster design. Four hundred thirty-eight overweight and obese children aged 7-12 years from ten primary schools in Beijing were recruited to receive a one-year intervention. Participants were allocated into one of four groups: the comprehensive intervention group; the PA only group (Happy 10 program); the diet only group (nutrition education program); and a control group. The effects of intervention on adiposity, blood pressure, and biochemical indicators were assessed by examining 2-way interactions (time × intervention) in linear mixed models. Means and 95 % confidence intervals (CI) for the adjusted changes between post-intervention and baseline relative to changes in the control group were calculated and reported as effect sizes. The percentage of body fat in the comprehensive intervention group showed a significant relative decrease (adjusted change: -1.01 %, 95 % CI: (-1.81, -0.20) %) compared with the PA only, diet only or control groups (P < 0.001). Systolic blood pressure significantly decreased in the comprehensive intervention group (adjusted change: -4.37 mmHg, 95 % CI: (-8.42, -0.33) mmHg), as did diastolic blood pressure (adjusted change: -5.50 mmHg, 95 % CI (-8.81, -2.19) mmHg) (P < 0.05). Compared with the other two intervention groups and the control group, positive adjusted changes in fasting glucose in the comprehensive group were found, although not for the biochemical lipid metabolism indicators. Positive but non-significant adjusted changes in body mass index and waist circumference were observed. Compared with the diet or PA only intervention groups, the current comprehensive program had superior positive effects on body fat percentage and blood pressure but not on the biochemical lipid metabolism indicators in Chinese overweight and obese children. Future randomized controlled trials and long-term follow-up studies are required to elaborate the findings of the current intervention. ClinicalTrials.gov identifier: NCT02228434.

Childhood anxiety is a problem not only because of its negative consequences on the well-being of children but also because of its adverse effects on society and its role in mental disorders later in life. Adequate prevention might be the key in tackling this problem. The effectiveness of Coping Cat, as an indicated CBT-based prevention program in Dutch primary school children, was assessed by means of a randomized controlled trial. In total, 141 children aged 7-13 with elevated levels of anxiety and their mothers were included and randomly assigned to an intervention group and a waiting list control group. After screening, all participants completed baseline, post-intervention, and 3-month follow-up assessments. The results showed that Coping Cat, as an indicated prevention program, reduces children's self-reported anxiety symptoms, with Cohen's effect size d of 0.66 at the 3-month follow-up. A moderating effect was found for baseline anxiety level; specifically, children with high levels of baseline anxiety who received the Coping Cat program had lower anxiety levels at follow-up compared to children with high levels of anxiety in the control condition. No moderating effects of gender or age were found. An unexpected decline in anxiety levels from screening to pre-assessment was found in both groups, and this decline was stronger in the experimental group. These promising results warrant the implementation of Coping Cat as an indicated prevention program.

The purpose of this study was to evaluate conventional acupuncture therapy in the management of clinical outcomes for temporomandibular disorders (TMD) in adults. The electronic databases PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Clinical Trails.gov were searched for reports published until March 31, 2016. Nine eligible studies from 8 publications involving 231 patients were included in the meta-analysis. A comparison of the main outcome of visual analog scale (VAS) values of pain between the acupuncture group and control group showed a significant decrease (MD = -0.98, 95% CI [-1.62, -0.34], I=54%, P = 0.003) in the VAS following acupuncture treatment. However, subgroup analysis according to the type of sham control group indicated that there were significant differences in the results when sham acupuncture was used as the control group (MD = -1.54, 95% CI [-2.63, -0.45], I=58%, P = 0.006) as well as when sham laser treatment was used as the control group (MD = -1.29, 95% CI [-2.32, -0.27], I = 0%, P = 0.01). However, there was no significant difference when the splint treatment group was used as the control group (MD = -0.09, 95% CI [-0.69, 0.50], I = 0%, P = 0.76). Subgroup analyses of VAS for pain by the classification of diseases indicated that the myogenous TMD subgroup demonstrated a significant difference (MD = -1.49, 95% CI [-2.45, -0.53], I = 47%, P = 0.002), and TMD showed no statistically significant difference (MD = -0.42, 95% CI [-1.14, 0.30], I = 46%, P = 0.25). Subgroup analysis according to whether the subgroup penetrated the skin showed that nonpenetrating sham acupuncture as the control group showed a significant difference (MD = -1.56, 95% CI [-2.70, -0.41], I = 58%, P = 0.008) compared with the conventional acupuncture as the treatment modality, while penetrating sham acupuncture as the control group showed no significant difference (MD = -1.29, 95% CI [-3.40, 0.82], I = not applicable, P = 0.23). No publication bias was observed considering the symmetry of the funnel plots. Our results indicate that conventional acupuncture therapy is effective in reducing the degree of pain in patients with TMD, especially those with myofascial pain symptoms.

Strength deficits of hip extension in individuals with patellofemoral syndrome are commonly reported in literature. No literature to date has examined these deficits with variable positions of the knee and hip; altering knee angle alters the length and therefore potentially the force produced by the biarticular muscles. Beyond strength, neuromuscular control can also be assessed through the analysis of isometric joint moment steadiness. Subjects consisted of a group of individuals with patellofemoral syndrome (n = 9), and a group of age- and size-matched controls with no symptoms (n = 9). Maximum isometric joint moments for hip extension were measured at 4 points within the joint's range of motion, at 2 different knee positions (0° and 90°) for each group. The joint moment signals were analyzed by computing signal Coefficient of Variation (CV). The results indicate that no significant differences were found between the groups of subjects for the hip extension moments when the knee was extended. However, there was a significant difference between the groups for the joint moments of hip extension with the knee flexed at all 4 hip positions. Results also showed hip extension CV values to be significantly higher in the patellofemoral group compared with the control group, indicating greater signal noise and therefore poorer neuromuscular control of the hip extensor musculature. This study demonstrated that individuals with patellofemoral syndrome have reduced hip extension strength and reduced neuromuscular control with the knee flexed compared with a control group. These results have implications for the etiology of patellofemoral syndrome and its rehabilitation.

To evaluate the safety and efficacy of combining Endostar antiangiogenic therapy with neoadjuvant chemotherapy for the treatment of stage IIIA (N2) NSCLC, we conducted a randomized, controlled, open-label clinical study of 30 NSCLC patients. Patients were randomly assigned to the test or control groups, which received either two cycles of an NP neoadjuvant chemotherapy regimen combined with Endostar or the NP regimen alone, respectively, at a 2:1 ratio. Efficacy was assessed after 3 weeks, and surgical resection occurred within 4 weeks, in the 26 patients who successfully completed treatment. While total response rates (RR) and clinical benefit rates (CBR) did not differ between the experimental groups, total tumor regression rates (TRR) were higher in the test group than in the control group. Median DFS and OS also did not differ between the test and control groups. Clinical perioperative indicators, including intraoperative blood loss, number of dissected lymph node groups, duration of postoperative indwelling catheter use, and time to postoperative discharge, were comparable in the test and control groups. Finally, hematological and non-hematological toxicities and postoperative pathological indicators, including down-staging ratio, complete resection ratio, and metastatic lymph node ratio, also did not differ between the groups. Overall, combining Endostar with NP neoadjuvant chemotherapy increased therapeutic efficacy without increasing adverse effects in stage IIIA-N2 NSCLC patients. This study is registered with ClinicalTrials.gov (number NCT02497118).

This study investigated the effect of active-learning strategies on college students' achievement, motivation, and self-efficacy in a human physiology course for nonmajors. Variables were studied via a quasi-experimental, Solomon four-group design on 141 students at a small west-Texas university. Treatment groups were taught using a continuum-based, active-learning model implemented over the course of a semester. Control groups were taught using traditional didactic lecture methods. To assess the effects of the continuum-based active learning strategies, students were administered a comprehensive physiology content exam, the Motivated Strategies for Learning Questionnaire, and attitude surveys. Factorial analyses indicated that the treatment groups acquired significantly more content knowledge and were significantly more self-efficacious than students in the control groups. There were no significant differences in motivation. Attitude surveys indicated that students in both the treatment and control groups demonstrated a positive attitude toward active learning, believed it helped (or would help) them to learn the material, and would choose an active learning course in the future.

Health-care-associated infections are a major threat to the safety of patient care. Control of such problem is a major criterion for hospital accreditation. This study was aimed to determine the developing use of chemical (class 6 products) and biological indicators in Tabriz district hospitals since 1997 to 2011. We conducted this time-trend interventional study with all of the public and private hospitals, which counted to 21 in Tabriz district as a sample. The situations of indicator use were presented for each time in the base of indicator groups. Furthermore, the results were showed in the base of hospital groups. All of district hospital (n=21) with 74 autoclave machine and 22 central sterilization room were studied. The result of second time study in 2008 showed a markedly improvement in the control of sterilization processes. Furthermore, we continued our intervention results 6 month later in 2009 and 2 years later in 2011. The most striking result were use of chemical indicator in 100% of hospitals. However, there are defects in the use of biological indicators (63.65%). The most obvious finding was significant improvement in sterilization control especially in development the use of chemical indicators. The finding of this study has a number of important implications for hospital managers and infection control practitioners such as continuous practical training of CSSD personnel in hospitals and mandating of indicator using in all sterilization process with controlling of this subject in evaluation and accreditation of hospital programs.

The main goal of this study was to evaluate the long-term effects of a brief group cognitive-behavioral (CB) adolescent depression indicated prevention program through 2-year follow-up, relative to CB bibliotherapy and brochure control, when high school personnel recruited students and delivered the program. Three hundred seventy-eight adolescents (M age = 15.5, SD = 1.2; 68% female, 72% White) with elevated self-assessed depressive symptoms who were randomized to CB group, CB bibliotherapy, or educational brochure control were assessed at pretest, posttest, and 6-, 12-, 18-, and 24-month follow-up. By 2 years postintervention, CB group participants showed significantly lower major depressive disorder (MDD) onset versus CB bibliotherapy (10% vs. 25%, respectively; hazard ratio = 2.48, p = .006), but the incidence difference relative to brochure controls (17%) was nonsignificant; MDD incidence for bibliotherapy and brochure controls did not differ. Although CB group participants showed lower depressive symptoms at posttest versus brochure controls, there were no effects for this outcome or for social adjustment or substance use over 2-year follow-up. Moderator analyses suggested that participants with higher baseline depressive symptoms showed greater long-term symptom reductions in the CB group intervention versus bibliotherapy. The evidence that a brief CB group intervention delivered by real-world providers significantly reduced MDD onset versus CB bibliotherapy is potentially encouraging. However, the lack of MDD prevention effects relative to brochure control and lack of long-term symptom effects (though consistent with results from other depression prevention trials), suggest that the delivery of the CB group should be refined to strengthen its effectiveness.

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.

This study aimed to evaluate the effect of a diet prepared with traditional sourdough (TS) on iron status. Levels of blood hemoglobin (Hb), Hematocrite (Ht), serum ferritin and serum iron as well as excreted iron were determined in three groups of mice fed with: TS bread (TS group), baking yeast bread (BY group) or bread with no starters (control group), respectively. The results show that the levels of Hb, Ht, ferritin and iron were significantly higher in the TS compared to the BY and control groups. Also a significant decrease in the excreted iron levels was observed in the mice fed with TS compared to the others dietary groups. In conclusion, the study results indicate an improvement of iron status indicators in mice when they were fed sourdough bread as compared to baking yeast bread and bread with no starters.

The purpose of this study was to determine the clinical utility of left atrial (LA) functional indexes in patients with mitral valve prolapse (MVP) and mitral regurgitation (MR). Timing of surgery for MVP remains challenging. We hypothesized that assessment of LA function may provide diagnostic utility in these patients. We studied 192 consecutive patients in sinus rhythm with MVP, classified into 3 groups: moderate or less MR (MOD group, n = 54); severe MR without surgical indication (SEV group, n = 52); and severe MR with ≥1 surgical indication (SURG group, n = 86). Comparison was made with 50 control patients. Using 2D speckle imaging, average peak contractile, conduit, and reservoir atrial strain was recorded. Using Simpson's method we recorded maximal left atrial volume (LAVmax) and minimal left atrial volume (LAVmin), from which the total left atrial emptying fraction (TLAEF) was derived: (LAVmax-LAVmin)/LAVmax × 100%. TLAEF was similar in the MOD and control groups (61% vs. 57%; p = NS), was reduced in the SEV group (55%; p < 0.001 vs. control group), and markedly lower in the SURG group (40%; p < 0.001 vs. other groups). Reservoir strain demonstrated a similar pattern. Contractile strain was similarly reduced in the MOD and SEV groups (MOD 15%; SEV 14%; p = NS; both p < 0.05 vs. control group 20%) and further reduced in the SURG group (8%; p < 0.001 vs. other groups). By multivariate analysis, TLAEF (odds ratio [OR]: 0.78; p < 0.001), reservoir strain (OR: 0.91; p = 0.028), and contractile strain (OR: 0.86; p = 0.021) were independent predictors of severe MR requiring surgery. Using receiver-operating characteristic analysis, TLAEF <50% demonstrated 91% sensitivity and 92% specificity for predicting MVP with surgical indication (area under the curve: 0.96; p < 0.001). We report the changes in left atrial function in humans with MVP and the relationship of LA dysfunction to clinical indications for mitral valve surgery. We propose that the findings support the utility of quantitative assessment of atrial function by echocardiography as an additional tool to guide the optimum timing of surgery for MVP.

This study was conducted to develop a customized birth control program and identify its effects on attitude, subjective norm, behavioral control, intention, and behavior of contraception among immigrant postpartum mothers. In this experimental study, Vietnamese, Filipino or Cambodian married immigrant postpartum mothers were recruited. They were assigned to the experiment group (n=21) or control group (n=21). The customized birth control program was provided to the experimental group for 4 weeks. The experimental group showed a significant increase in the score of attitude, subjective norm, behavioral control, intention, and behavior of contraception. Findings in this study indicate that the customized postpartum birth control program, a systematic and integrative intervention program composed of customized health education, counseling and telephone monitoring, is able to provide effective planning for postpartum health promotion and birth control behavior practice in married immigrant women.

Although the research on cyberbullying has increased dramatically in recent years, still little is known about how cyberbullying participant groups (i.e., cyberbullies, cybervictims, and cyberbully-victims) differ from one another. This study aims to discriminate between these groups at an individual and relational level by controlling for age and gender. Self-control, offline aggression, and self-esteem are analyzed as individual-level variables. Parental attachment and peer rejection are involved as relational-level variables. A total of 2,092 Czech adolescents aged 12 to 18 were enrolled from a random sample of 34 primary and secondary schools located in the South Moravian region of the Czech Republic. Discriminant function analyses indicated that the participant groups are discriminated by two functions. The first function increases the separation between cyberbullies and cyberbully-victims from cybervictims, indicating that cyberbullies and cyberbully-victims are similar to each other in terms of low self-control, offline aggression, and gender, and have higher scores on measures of low self-esteem and offline aggression. However, cyberbully-victims had the highest scores on these measures. The second function discriminates between all three groups, which indicates that those variables included in the second function (i.e., parental attachment, peer rejection, self-esteem, and age) distinguish all three involved groups. © The Author(s) 2014.

In tropical and semitropical regions, raising broiler chickens out of their thermal comfort zone can cause an added economic loss in the poultry industry. The cause for the deleterious effects on immunity and growth performance of broilers under high environmental temperatures is still poorly understood. Therefore, the aim of the current investigation was to evaluate the effect of heat stress on leukocytes protein synthesis and immune function as a possible direct cause of low performance in broiler chickens under such condition. In this study, 300 one-day-old male broiler chicks (Cobb500™) were randomly assigned into 2 groups with 5 replicates of 30 chicks each. From 21 to 42 days of age, one group was exposed to non-stressed condition at 24 °C and 50% relative humidity (control group), while the other group was exposed to heat stress at 35 °C and 50% relative humidity (HS group). At 42 days of age, blood samples were collected from each group to evaluate stress indicators, immune function, and leukocytes protein synthesis. Production performance was also recorded. Noteworthy, protein synthesis in leukocytes was significantly ( P < 0.05) inhibited in HS group by 38% compared to control group. In contrast, the phosphorylation level on threonine 56 site (Thr56) of eukaryotic elongation factor (eEF2), which indicates the suppression of protein translation process through altering the protein elongation phase, was significantly threefold higher in HS group than in control ( P < 0.05). In addition, an increase in stress indicators was markedly ( P < 0.05) presented in the HS birds by twofold increase in heterophil/lymphocyte (H/L) ratio and threefold increase in plasma corticosterone level compared to control. Furthermore, the immune function was significantly ( P < 0.05) suppressed in HS birds than control (0.99 vs. 1.88 mg/mL plasma IgG, 89.2 vs. 148.0 μg/mL plasma IgM, 4.80 vs. 7.20 antibody titer against SRBC, and 1.38 vs. 3.39 stimulation index of lymphocyte proliferation in HS vs. control group, respectively). Moreover, results on the broiler performance indicate that HS birds had a significant ( P < 0.05) lower body weight gain by 58%, lower feed consumption by 39%, higher conversion ratio by 27%, and higher mortality by more than three times, compared to control birds. In conclusion, our results demonstrate that the inhibition of leukocyte protein synthesis through increasing the level of eEF2 Thr56 phosphorylation may play a key role in the observed decrease in immune function and growth performance with the high mortality rate encountered in broiler chickens under heat stress environment.

Clinical quality indicators are necessary to monitor the performance of healthcare services. The development of indicators should, wherever possible, be based on research evidence to minimise the risk of bias which may be introduced during their development, because of logistic, ethical or financial constraints alone. The development of automated methods to identify the evidence base for candidate indicators should improve the process of indicator development. The objective of this study is to explore the relationship between clinical quality indicators for asthma management in children with outcome and process measurements extracted from randomised controlled clinical trial reports. National-level indicators for asthma management in children will be extracted from the National Quality Measures Clearinghouse (NQMC) database and the National Institute for Health and Care Excellence (NICE) quality standards. Outcome measures will be extracted from published English language randomised controlled trial (RCT) reports for asthma management in children aged below 12 years. The two sets of measures will be compared to assess any overlap. The study will provide insights into the relationship between clinical quality indicators and measurements in RCTs. This study will also yield a list of measurements used in RCTs for asthma management in children, and will find RCT evidence for indicators used in practice. Ethical approval is not necessary because this study will not include patient data. Findings will be disseminated through peer-reviewed publications. Published by the BMJ Publishing Group Limited.

2005-11-01

Research indicates that attentional deficits exist in aphasic individuals. However, relatively little is known about auditory vigilance performance in individuals with aphasia. The current study explores reaction time (RT) and accuracy in 10 aphasic participants and 10 nonbrain-damaged controls during linguistic and nonlinguistic auditory vigilance tasks. Findings indicate that the aphasic group was less accurate during both tasks than the control group, but was not slower in their accurate responses. Further examination of the data revealed variability in the aphasic participants' RT contributing to the lower accuracy scores.

The aim of research is to study of the spirometry figures of bronchoobstructive syndrome in concomitant intestinal parasitosis. There are 81 patients aged from 5 to 61 years (male 43, female 38) were examined. The patients were divided into 2 groups: 1 group - patients treated only with bronchodilator therapy (14 patients with protozoa, 14 - with helminth, 12 - with combination of parasitosis); 2 group - patients treated with bronchodilator therapy in common with anti-parasitic therapy (14 patients with protozoa, 17 - with helminth, 10 - with combination of parasitosis). There are 22 patients with bronchoobstructive syndrome without parasites were included in control group. Functional disorders at the initial examination are not significantly distinguished between patients with protozoa, helminth, with combined parasitosis and patients without parasites. Considerable differences manifested in dynamics after treatment: only bronchodilator therapy of patients infected with parasites is not lead to sufficient increase of the indices of external respiration function, even the decreasing of the most parameters were observed in patients with helminth. The least growth of spirometric indices were observed in patients from group 1 - 2,17/ 5,09% predicted volumes (-6,81min; 10,54max), the highest growth were observed in patients from group 2 - 20,26/ 12,45% p.v. (2,77min; 43,85max). The spirographic indicators increase after treatment in the control group was more moderate in comparison with 1 and 2 groups - 5,96/ 2,97% p.v. (0,39min; 9,59max). Thus, using antiparasitic therapy in common with bronchodilator therapy in treatment of patients with intestinal parasitosis (group 2) is lead to the reliably significant positive dynamic of spirometry parameters in comparison not only to 1 group (<0,05 for many parameters) but also to control group (<0,01 for many parameters).

Clinical research and practice support a multi-method approach to validating behavioral problems in children. We examined whether parent-reported symptoms of hyperactivity and inattention (using the Disruptive Behavior Disorder Rating Scale) were substantiated by objective laboratory measures [hyperactivity measured by wrist-worn actigraphy (ACT) and inattention assessed using a 20-minute continuous performance task (CPT)] in three age- and demographically-matched groups of school-age children: children with prenatal alcohol exposure (AE), non-exposed children with idiopathic ADHD (ADHD), and controls (CON). Results indicated that the clinical groups (AE, ADHD) had significantly higher parent-reported levels for both domains compared to the CON group, and did not differ from each other. On the laboratory measures, the clinical groups were more inattentive than controls on the CPT, but did not differ from each other. In contrast, the ADHD group had higher objective activity on the ACT than AE and CON, which did not differ from each other. Thus, laboratory measures differentially validated parent reports in a group-dependent manner. Actigraphy substantiated parent-reported hyperactivity for children in the ADHD group but not for children in the AE group, while the CPT validated parent-reported inattention for both clinical groups. Although the majority of children in the AE group met criteria for ADHD, objective activity levels were not different from controls, indicating that hyperactivity may be a less prominent feature in the AE group. Thus, while there is considerable overlap between the effects of prenatal alcohol exposure and ADHD, differences in behavioral profiles may be clinically useful in differential diagnosis. Further, these data indicate that objective measures should be used to validate parent reports. PMID:24512965

Objective The purpose of the present study was to compare mandibular vertical asymmetry in patients with unilateral and bilateral cleft lip and palate and subjects with normal occlusion. Materials and Methods Cone beam computed tomography scans of three groups consisting of 20 patients with unilateral cleft lip and palate, 20 patients affected by bilateral cleft lip and palate, and a control group of 20 subjects with normal occlusion were analyzed for this study. Condylar, ramal, and condylar plus ramal asymmetry indices were measured for all subjects using the method of Habets et al. Kruskal-Wallis and Mann-Whitney tests were used to determine any significant differences between the groups for all indices at the 95% level of confidence. Results There were no significant differences regarding sex for all mandibular asymmetry indices in all three groups. All Asymmetry indices (condylar, ramal, and condylar plus ramal asymmetry) were significantly higher in the unilateral cleft group compared with the other two groups. Conclusion Cone beam computed tomography images showed that patients with cleft lip and palate suffered from mandibular asymmetry. Subjects with unilateral cleft lip and palate had a more asymmetric mandible compared with the bilateral cleft lip and palate and control groups. Therefore, the mandible appears to be the leading factor in facial asymmetry in subjects with unilateral cleft lip and palate.

Early-phase and preclinical studies suggest that moxifloxacin-containing regimens could allow for effective 4-month treatment of uncomplicated, smear-positive pulmonary tuberculosis. We conducted a randomized, double-blind, placebo-controlled, phase 3 trial to test the noninferiority of two moxifloxacin-containing regimens as compared with a control regimen. One group of patients received isoniazid, rifampin, pyrazinamide, and ethambutol for 8 weeks, followed by 18 weeks of isoniazid and rifampin (control group). In the second group, we replaced ethambutol with moxifloxacin for 17 weeks, followed by 9 weeks of placebo (isoniazid group), and in the third group, we replaced isoniazid with moxifloxacin for 17 weeks, followed by 9 weeks of placebo (ethambutol group). The primary end point was treatment failure or relapse within 18 months after randomization. Of the 1931 patients who underwent randomization, in the per-protocol analysis, a favorable outcome was reported in fewer patients in the isoniazid group (85%) and the ethambutol group (80%) than in the control group (92%), for a difference favoring the control group of 6.1 percentage points (97.5% confidence interval [CI], 1.7 to 10.5) versus the isoniazid group and 11.4 percentage points (97.5% CI, 6.7 to 16.1) versus the ethambutol group. Results were consistent in the modified intention-to-treat analysis and all sensitivity analyses. The hazard ratios for the time to culture negativity in both solid and liquid mediums for the isoniazid and ethambutol groups, as compared with the control group, ranged from 1.17 to 1.25, indicating a shorter duration, with the lower bounds of the 95% confidence intervals exceeding 1.00 in all cases. There was no significant difference in the incidence of grade 3 or 4 adverse events, with events reported in 127 patients (19%) in the isoniazid group, 111 (17%) in the ethambutol group, and 123 (19%) in the control group. The two moxifloxacin-containing regimens produced a more rapid initial decline in bacterial load, as compared with the control group. However, noninferiority for these regimens was not shown, which indicates that shortening treatment to 4 months was not effective in this setting.

To investigate the relationship between general physical activity level and the cognitive functions of executive control in young adults using behavioral measures and event-related brain potentials. Forty young adults (mean age=21.1 yrs; 19 females) were differentiated on the basis of their regular physical activity level into two groups: active and sedentary. They performed a spatial priming task consisting of three conditions: control, positive, and negative priming. Spatial priming effects, which are related to executive control and occur automatically, were assessed as indicators of cognitive functioning. Negative priming effects on reaction time and P3 latency in the active group were larger than in the sedentary group. By contrast, positive priming effects were only observed in the sedentary group. The cognitive effects of regular physical activity could be observed using a relatively simple paradigm. The results indicate that regular physical activity has a beneficial effect on the cognitive processes on executive control in young adults. The present study provides additional evidence of the beneficial effects of regular physical activity on cognitive functioning in young adults.

Fresh culinary-medicinal Shiitake mushrooms (Lentinus edodes) were pretreated by soaking in 0.1 mg/mL of L-cysteine solution for 1 hour; then the variation in formaldehyde content and browning degree were studied during hot air-drying and canning processes. The results indicated that L-cysteine pretreatment significantly inhibited the increase of formaldehyde content and browning during the drying process; these increases in the pretreatment groups ranged from 7.0% to 14.0% and 65.4% to 68.9%, respectively, of that of the control groups. While the L-cysteine pretreatment did not seem to have a significant effect on controlling the formaldehyde content during the canning process, the increase of the browning degree of the canned products of the pretreatment groups ranged from 64.8% to 78.5% of that of the control groups, indicating the inhibitive effect of L-cysteine on browning during the canning process of L. edodes. Overall, L-cysteine pretreatment improved the sensory quality of both dried and canned L. edodes.

Development of intrauterine growth restriction (IUGR) can be traced back to maternal or fetal factors, but in many cases we find placental factors (reduced placental circulation) in the background. Our aim was to examine whether the reduced placental bloodperfusion and vascularity show any correlation with cesarean section frequency and the clinical outcome in IUGR pregnancies. The aim of the present study was also to use a properly calibrated and reproducible method for evaluating placental blood flow, that can later be incorporated into the routine examination. 254 women were recruited in our prospective case-control study. The 3 dimensional power Doppler (3DPD) ultrasound indices; vascularisation index (VI), flow index (FI) and vascularization flow index (VFI) were measured on each participant. Median VI was 3.7% (interquartile range [IQR] 3.2%-4.2%) in the IUGR group and 10.1% (IQR 8.6%-10.9%) in the control group (p = 0.001). Median FI value was 40.0 (IQR 39.7-42.5) in the IUGR group and 45.1 (IQR 44.1-53.1) in the control group (p = 0.012). Median VFI was 2.2 (IQR 2.1-2.4) in the IUGR group and 4.8 (IQR 4.4-5.3) in the control. The 3DPD indices may be useful for examining changes in circulation in IUGR pregnancies to characterize the underlying pathology. Orv Hetil. 2017; 158(26): 1008-1013.

Background During recent decades, research in Iran in the area of the Quran and medical science has been seriously engaged in. With respect to the tendency toward spirituality and alternative medicine, we tried to find other aspects of the influence of the Quran. Objectives This study aimed to determine the effect of vocalizations of the Holy Quran with and without translation on the consequences of pregnancy (the prevalence of preterm delivery, caesarean delivery, and neonatal anthropometric indices) in women admitted to health care centers in Urmia, Iran. Materials and Methods This was a three-armed parallel-group randomized clinical trial in which 168 pregnant women (25-28 weeks) in their first and second pregnancies were divided into three groups of 56 (Holy Quran with translation, Holy Quran without translation, and control group) by randomized blocking. The intervention was implemented once a week for three weeks in the health center, and on other days of the week, the participants listened at home to a CD they were given. The intervention and the control groups all received routine pregnancy care once a week. These mothers were tracked during their labor. Outcomes including gestational age at delivery, delivery type, and neonatal anthropometric indices were recorded based on the mother’s records. Results There was no statistically significant difference between the groups in terms of demographic and obstetric characteristics before the intervention. In comparison with the control group, the probability of preterm delivery was lower in the Holy Quran with translation group (odds ratio: 0.3, CI 95%: 0.1-1.2) and in the Holy Quran without translation group (0.6, 0.2-1.9) as compared to the control group. However, this difference was not statistically significant. Similarly, the probability of caesarean delivery was lower in the Holy Quran with translation group (0.6, 0.3-1.4) and the Holy Quran without translation group (0.5, 0.2-1.2) as compared to the control group. Based on one-way ANOVA, there was no statistically significant difference between the study groups regarding the infants’ anthropometric indices. Conclusions Based on the results of this study, despite the lower prevalence of preterm labor and caesarean section in the intervention groups as compared to the control group, no statistically significant effect was seen. This was apparently due to the small sample size. PMID:28144462

Satellite telemetry has become a leading method for studying large-scale movements and survival in birds, yet few have addressed potential effects of the larger and heavier tracking equipment on study subjects. We simultaneously evaluated effects of satellite telemetry equipment on captive and wild mallards (Anas platyrhynchos) to assess impacts on behavior, body mass, and movement. We randomly assigned 55 captive ducks to one of 3 treatment groups, including a standard body harness group, a modified harness group, and a control group. Ducks in the control group were not fitted with equipment, whereas individuals in the other 2 groups were fitted with dummy transmitters attached with a Teflon ribbon harness or with a similar harness constructed of nylon cord. At the conclusion of the 14-week captive study, mean body mass of birds in the control group was 40–105 g (95% CI) greater than birds with standard harnesses, and 28–99 g (95% CI) greater than birds with modified harnesses. Further, results of focal behavior observations indicated ducks with transmitters were less likely to be in water than control birds. We also tested whether movements of wild birds marked with a similar Teflon harness satellite transmitter aligned with population movements reported by on-the-ground observers who indexed local abundances of mid-continent mallards throughout the non-breeding period. Results indicated birds marked with satellite transmitters moved concurrently with the larger unmarked population. Our results have broad implications for field research and suggest that investigators should consider potential for physiological and behavioral effects brought about by tracking equipment. Nonetheless, results from wild ducks indicate satellite telemetry has the potential to provide useful movement data.

Six- and nine-yr.-old children (n=28 of each) were divided into equal experimental and control groups. The experimental groups were shown a film with a magical theme, and the control groups were shown a film with a nonmagical theme. All groups then were presented with a choice task requiring them to discriminate between ordinary and fantastic visual displays on a computer screen. Statistical analyses indicated that mean scores for correctly identifying the ordinary and fantastic displays were significantly different between experimental and control groups. The children in the experimental groups who watched the magical film had significantly higher scores on correct identifications than children in the control groups who watched the nonmagical film for both age groups. The results suggest that watching films with a magical theme might enhance children's sensitivity toward the fantasy/reality distinction.

The benefit of heart rate variability biofeedback and relaxation training in reducing trait anxiety.

Lee, Jieun; Kim, Jung K; Wachholtz, Amy

Previous research studies have indicated that biofeedback treatment and relaxation techniques are effective in reducing psychological and physical symptoms (Hammond, 2005; Manzoni, G. M., Pagnini, F., Castelnuovo, G., & Molinari, E., 2008). However, dearth of studies has compared heart rate variability (HRV) biofeedback treatment and relaxation training to reduce trait anxiety. The objective of this study was to determine the effect of HRV biofeedback treatment and relaxation training in reducing trait anxiety compared to control group without any treatment using students in a science and engineering university of South Korea. For the present study, a total of 15 graduate students with moderate level of trait anxiety were recruited for 4 individual sessions every two weeks. They were randomly assigned into three groups: biofeedback treatment (n = 5), relaxation training (n = 5), and no treatment control group (n = 5). Our results revealed significant difference in change score of trait anxiety between the HRV biofeedback treatment and the no treatment control group. However, no significant difference was found between the relaxation training group and the no treatment control group. In addition, there was no significant difference between the HRV biofeedback treatment and the relaxation training. Results of the present study indicate that there is potential benefit in utilizing HRV biofeedback treatment for stress management programs and/or anxiety reduction treatment.

The use of a control group is fundamental to experimental research design, though the use with clinical populations must be carefully considered. The purpose of this research was to examine the use of control groups in research with clinical and nonclinical populations published in Journal of Musical Therapy from 1964 through 2004. Criteria for inclusion were music or music therapy as an independent variable applied to one or more groups and at least one control group that did not receive a music treatment. Control groups were qualified as alternative treatment, placebo, no contact, and treatment as usual. Of the 692 articles, 94 met these criteria, 62 clinical and 32 nonclinical, representing 13.5% of the publications. Results indicated that research with clinical populations involved a mean of 38.1 subjects typically divided into two groups, an experimental and a control group. The pretest-posttest design was the most common (55%) as was a treatment as usual control group (45%). These design methods maximized the impact of the experimental music treatment on outcome. Experimental music groups significantly improved over control groups in the vast majority of studies identified. Undoubtedly, the foundation for evidence-based clinical practice is firm.

To gain insight into the ovarian stromal blood flow in women with polycystic ovary syndrome (PCOS) as compared with women with normal ovulation, good ovarian reserve, and infertility and to evaluate the role of stromal flow in these patients to predict clinical pregnancy in an assisted reproductive technologies setting. A prospective observational cohort study. A university-affiliated reproductive medicine unit. Eighteen consecutive patients with PCOS (study) compared with 101 patients with normal ovulation and infertility (control), undergoing their first IVF-ET treatment at our unit. Women with low ovarian reserve were excluded a priori from evaluation. Basal ovarian reserve parameters and stromal flow studies were conducted as routinely performed in our unit, in a natural cycle before starting treatment. None. Basal ovarian endocrine, sonographic, and stromal flow studies were compared between the groups. After completion of treatment, the stromal flow studies were compared between conception and nonconception cycles. Patients' characteristics and basal ovarian reserve, including endocrine and sonographic parameters, were similar between the PCOS and control groups. Only antral follicle count and LH/FSH ratio were higher in the PCOS as compared with the control group, corresponding to 15.11 ± 6.05 versus 9.05 ± 4.77 and 1.14 ± 0.64 versus 0.79 ± 0.37, respectively. Basal stromal flow indices were similar between the PCOS group and the group with normal ovulation and good ovarian reserve. Clinical pregnancy rate per initiated cycle was 50.0% and 39.6% in the PCOS and control groups, respectively, with no significant difference. Flow indices were similar between conception cycles in the PCOS and control groups. As well, the indices did not differ significantly between conception and nonconception cycles within the PCOS and control groups. Basal ovarian stromal blood flow does not differ between women with PCOS and women with normal ovulation, good ovarian reserve, and infertility. Moreover, stromal flow has no predictive value, in these patients, for clinical pregnancy achievement in an IVF-ET setting. Copyright © 2011 American Society for Reproductive Medicine.

Background: This study explores effects of instrumental music on the hormonal system (as indicated by serum cortisol and adrenocorticotropic hormone), the immune system (as indicated by immunoglobulin A) and sedative drug requirements during surgery (elective total hip joint replacement under spinal anesthesia with light sedation). This is the first study investigating this issue with a double-blind design using instrumental music. Methodology/Principal Findings: Patients (n = 40) were randomly assigned either to a music group (listening to instrumental music), or to a control group (listening to a non-musical placebo stimulus). Both groups listened to the auditory stimulus about 2 h before, and during the entire intra-operative period (during the intra-operative light sedation, subjects were able to respond lethargically to verbal commands). Results indicate that, during surgery, patients of the music group had a lower propofol consumption, and lower cortisol levels, compared to the control group. Conclusion/Significance: Our data show that listening to music during surgery under regional anesthesia has effects on cortisol levels (reflecting stress-reducing effects) and reduces sedative requirements to reach light sedation.

Our aim was to identify moderators of the effects of a cognitive behavioral group-based prevention program (CB group) and CB bibliotherapy, relative to an educational brochure control condition and to one another, in a school-based effectiveness randomized controlled prevention trial. 378 adolescents (M age = 15.5, 68% female) with elevated depressive symptoms were randomized in one of three conditions and were assessed at pretest, posttest, and 6-month follow-up. We tested the moderating effect of three individual (baseline depressive symptoms, negative attributional style, substance use), three environmental (negative life events, parental support, peer support), and two sociodemographic (sex, age) characteristics. Baseline depressive symptoms interacted with condition and time. Decomposition indicated that elevated baseline depressive symptoms amplified the effect of CB bibliotherapy at posttest (but not 6-month follow-up) relative to the control condition, but did not modify the effect of CB group relative to the control condition or relative to bibliotherapy. Specifically, CB bibliotherapy resulted in lower posttest depressive symptoms than the control condition in individuals with elevated, but not average or low baseline symptoms. We found no interaction effect for other putative moderators. Our findings suggest that bibliotherapy is effective only in participants who have elevated depressive symptoms at baseline. The fact that no study variable moderated the effects of CB group, which had a significant main effect in reducing depressive symptoms relative to the control condition, suggests that this indicated prevention intervention is effective for a wide range of adolescents.

This quasi-experimental study examined the effects of cognitive-behavioral therapy (CBT) to control depression, anger, and self-control in soldiers from South Korea. Using a pretest-posttest design, the sample was composed of an experimental group (n = 16) and a control group (n = 12). The experimental group participated in four sessions of CBT. No significant differences were found between the groups with regard to demographic characteristics. Changes in the variables after the intervention were analyzed using Wilcoxon's signed-rank sum test. The depression scores decreased significantly after the intervention (z = -3.05, p = 0.002); whereas, the scores of state-trait anger and self-control did not change. In the control group, none of the outcome variable scores changed significantly. The results indicate that the developed CBT program might be an effective modality to decrease the depression of soldiers who are in military service. Copyright 2014, SLACK Incorporated.

A controlled comparison of emotional reactivity and physiological response in masticatory muscle pain patients.

Schmidt, John E; Carlson, Charles R

2009-01-01

To investigate (1) differences in heart rate variability (HRV) indices between masticatory muscle pain (MMP) patients and pain-free controls at rest, during a stressor condition, and during a post-stressor recovery period, and (2) factors including psychological distress, social environment, and family-of-origin characteristics in the MMP sample compared to a pain-free matched control sample. Physiological activation and emotional reactivity were assessed in 22 MMP patients and 23 controls during baseline, stressor, and recovery periods. Physiological activity was assessed with frequency domain HRV indices. Emotional reactivity was assessed with the Emotional Assessment Scale. Analytic strategy began with overall 2 x 3 multivariate analyses of variance on physiological data followed by focused contrasts to test specific hypotheses regarding physiological and emotional status. Hypothesized differences between study groups on psychological and social-environmental variables were compared with univariate analyses of variance. The MMP patients showed physiological activation during the baseline period and significantly more physiological activation during the recovery period compared to the controls. This pattern was also present in emotional reactivity between the groups. The emotional and physiological differences between the groups across study periods were more pronounced in pain patients reporting a traumatic stressor. These results provide further evidence of physiological activation and emotional responding in MMP patients that differentiates them from matched pain-free controls. The use of HRV indices to measure physiological functioning quantifies the degree of sympathetic and parasympathetic activation. Study results suggest the use of these HRV indices may improve understanding of the role of excitatory and inhibitory mechanisms in patients with MMP conditions.

The purpose of this study was to examine the effect of long-term self-massage at the musculotendinous junction on hamstring extensibility, stiffness, stretch tolerance, and structural indices. Single-blind, randomized, controlled trial. Laboratory. Thirty-seven healthy men. The right or left leg of each participant was randomly assigned to the massage group, and the other leg was assigned to the control group. The participants conducted self-massage at the musculotendinous junction for 3 min daily, five times per week, for 12 weeks. Hamstring extensibility, stiffness, stretch tolerance, and structural indices were measured by a blinded examiner prior to the massage intervention and after 6 and 12 weeks of intervention. The maximum hip flexion angle (HFA) and the maximum passive pressure after 6 and 12 weeks of intervention in the massage group were significantly higher than prior to intervention. The visual analog scale (for pain perception) at maximum HFA, the stiffness of the hamstring, and the structural indices did not differ in either group over the 12 week period. Our results suggest that long-term self-massage at the musculotendinous junction increases hamstring extensibility by improving stretch tolerance. However, this intervention does not change hamstring stiffness. University Hospital Medical Information Network registration number UMIN000011233. Copyright © 2016 Elsevier Ltd. All rights reserved.

In the community mental health field, occupational therapy students lack the capacity to prioritize referrals effectively. The purpose of this study was to test the effectiveness of a clinical decision-training aid on referral prioritization capacity. A double-blind, parallel-group, randomized controlled trial was conducted using a judgment analysis approach. Each participant used the World Wide Web to prioritize referral sets at baseline, immediate posttest, and 2-wk follow-up. The intervention group was provided with training after baseline testing; control group was purely given instructions to continue with the task. One hundred sixty-five students were randomly allocated to intervention (n = 87) or control (n = 81). Intervention. Written and graphical descriptions were given of an expert consensus standard explaining how referral information should be used to prioritize referrals. Participants' prioritization ratings were correlated with the experts' ratings of the same referrals at each stage of testing, as well as to examine the effect on mean group scores, regression weights, and the lens model indices. At baseline, no differences were found between control and intervention on rating capacity or demographic characteristics. Comparison of the difference in mean correlation baseline scores of the control and intervention group compared with immediate posttest showed a statistically significant result that was maintained at 2-wk follow-up. The effect size was classified as large. At immediate posttest and follow-up, the intervention group improved rating capacity, whereas the control group's capacity remained poor. The results of this study indicate that the decision-training aid has a positive effect on referral prioritization capacity. This freely available, Web-based decision-training aid will be a valuable adjunct to the education of these novice health professionals internationally.

Tibolone is a synthetic steroid with tissue-specific estrogenic, progestogenic, and androgenic properties. The therapeutic effects of tibolone on bone mass and strength, bone metabolic markers, and indices of histomorphometry were investigated in ovariectomized (ovx) rats on a low (0.1%)-calcium diet in comparison with 17alpha-ethynylestradiol (EE) or 1alpha-hydroxyvitamin D3 [1alpha(OH)D3]. Tibolone (0.1-3 mg/kg/day), EE (0.1 mg/kg/day), or 1alpha(OH)D3 (0.5 microg/kg/day) was administered orally once a day for 16 weeks, starting 12 weeks after ovariectomy, when the bone mineral density (BMD) of lumbar vertebrae (L4-5) and femur (global, proximal, and distal regions) had already been decreased by the combination of ovariectomy and low dietary calcium. The BMD of the lumbar vertebrae and the femur were higher in the groups treated with tibolone, EE, or 1alpha(OH)D3 than in the ovx control group. The BMD of the mid-diaphysial regions of femur and tibia, which consist mainly of cortical bone, were decreased 28 weeks after ovariectomy in the ovx control group. The BMD of the mid-diaphysial femur was higher in the groups treated with 1alpha-(OH)D3, and the BMD of mid-diaphysial tibia was higher in the groups treated with tibolone or 1alpha(OH)D3 than in the ovx control group. Like BMD, the compressive strength of the vertebral body of L2, corrected for the volume of each individual vertebra tested, was higher in the groups treated with tibolone, EE, or 1alpha(OH)D3 than in the ovx control group. Trabecular bone volume and trabecular number were reduced 12 and 28 weeks after ovariectomy but there was no change in trabecular thickness. These reduced indices were increased in the groups treated with tibolone, EE, or 1alpha(OH)D3 when compared with the ovx control group. Tibolone or EE decreased serum levels of osteocalcin and bone alkaline phosphatase and urinary levels of deoxypyridinoline and pyridinoline compared with the ovx control group. Furthermore, tibolone or EE decreased the mineralizing surface and bone formation rate as well as the osteoclast surface and osteoclast numbers. 1Alpha(OH)D3, however, did not affect these serum and urinary parameters. These data suggest that tibolone suppresses the accelerated bone turnover induced by a combination of ovariectomy and low dietary calcium, and indicate that tibolone may be a potentially useful drug for the treatment of postmenopausal osteoporosis.

To verify whether controlling for indicators of disease severity and confounders represents a solution to the obesity paradox in chronic heart failure (CHF). From a cohort of 1790 patients, we formed 230 nested matched triplets by individually matching patients with body mass index (BMI) > 30 kg/m(2) (Group 3), BMI 20-24.9 k/m(2) (Group 1) and BMI 25-29.9 kg/m(2) (Group 2), according to NT-proBNP, age, sex, and NYHA class (triplet = one matched patient from each group). Although in the pre-matching cohort, BMI group was a significant univariable prognostic indicator, it did not retain significance [heart rate (HR): 0.91, 95% CI: 0.78-1.05, chi(2): 1.67] when controlled for group propensities as covariates. Furthermore, in the matched cohort, 1-year mortality and 3-year mortality did not differ significantly. Here, BMI again failed to reach statistical significance for prognosis, either as a continuous or categorical variable, whether crude or adjusted. This result was confirmed in the patients not selected for matching. NT-proBNP, however, remained statistically significant (log(NT-proBNP): HR: 1.49, 95% CI: 1.13-1.97, chi(2): 7.82) after multivariable adjustment. The obesity paradox does not appear to persist in a matched setting with respect to indicators of disease severity and other confounders. NT-proBNP remains an independent prognostic indicator of adverse outcome irrespective of obesity status.

Context: Increased prevalence of type 2 diabetes mellitus and prediabetes worldwide is attributed in part to an unhealthy diet. Objective: To evaluate whether 12 weeks of high monounsaturated fatty acid (MUFA) or fiber-rich weight-maintenance diet lowers hepatic fat and improves glucose tolerance in people with prediabetes. Design: Subjects underwent a [6, 6-2H2]–labeled 75-g oral glucose tolerance test to estimate hepatic insulin sensitivity and liver fat fraction (LFF) using magnetic resonance spectroscopy before and after intervention. Setting: Mayo Clinic Clinical Research Trials Unit. Participants: 43 subjects with prediabetes. Intervention: Subjects were randomized into three isocaloric weight-maintaining diets containing MUFA (olive oil), extra fiber, and standard US food (control-habitual diet). Outcome Measures: LFF, glucose tolerance, and indices of insulin action and secretion. Results: Body weight was maintained constant in all groups during the intervention. Glucose and hormonal concentrations were similar in all groups before, and unchanged after, 12 weeks of intervention. LFF was significantly lower after intervention in the MUFA group (P < 0.0003) but remained unchanged in the fiber (P = 0.25) and control groups (P = 0.45). After 12 weeks, LFF was significantly lower in the MUFA than in the control group (P = 0.01), but fiber and control groups did not differ (P = 0.41). Indices of insulin action and secretion were not significantly different between the MUFA and control groups after intervention (P ≥ 0.11), but within-group comparison showed higher hepatic (P = 0.01) and total insulin sensitivity (P < 0.04) with MUFA. Conclusions: Twelve weeks of a MUFA diet decreases hepatic fat and improves both hepatic and total insulin sensitivity. PMID:28323952

Although group differences have been found between children with Down syndrome (DS) and typically developing (TD) children when considering sleep problems and temperament independently, none of the research conducted to date has examined sleep-temperament associations in children with DS. The present research was conducted to determine (1) whether the sleep problems experienced by children with DS are associated with temperament or (2) if the demonstrated relations between sleep and temperament differ from those that are observed in TD children. The present study included examination of relations between parent-reported sleep problems and temperament in 19 children with DS and 20 TD controls matched on developmental age. The results revealed group differences in temperament and sleep problems. Mediation models indicated that temperament (effortful control and inhibitory control) mediated the association between group and sleep problems; sleep problems also mediated the association between group and temperament (effortful and inhibitory control). Findings indicated that sleep problems may serve as both cause and consequence of variability in effortful and inhibitory control and provide insight as to future experimental studies that should be conducted to better elucidate these relations. © 2016 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

To investigate the effect of physician- and patient-specific feedback with benchmarking on the quality of care in adults with type 2 diabetes mellitus (T2DM). Study centres in six European countries were randomised to either a benchmarking or control group. Physicians in both groups received feedback on modifiable outcome indicators (glycated haemoglobin [HbA1c], glycaemia, total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein [LDL]-cholesterol and triglycerides) for each patient at 0, 4, 8 and 12 months, based on the four times yearly control visits recommended by international guidelines. The benchmarking group also received comparative results on three critical quality indicators of vascular risk (HbA1c, LDL-cholesterol and systolic blood pressure [SBP]), checked against the results of their colleagues from the same country, and versus pre-set targets. After 12 months of follow up, the percentage of patients achieving the pre-determined targets for the three critical quality indicators will be assessed in the two groups. Recruitment was completed in December 2008 with 3994 evaluable patients. This paper discusses the study rationale and design of OPTIMISE, a randomised controlled study, that will help assess whether benchmarking is a useful clinical tool for improving outcomes in T2DM in primary care.

Objective: To determine if the flexibility of high-school-aged males would improve after a 6-week eccentric exercise program. In addition, the changes in hamstring flexibility that occurred after the eccentric program were compared with a 6-week program of static stretching and with a control group (no stretching). Design and Setting: We used a test-retest control group design in a laboratory setting. Subjects were assigned randomly to 1 of 3 groups: eccentric training, static stretching, or control. Subjects: A total of 69 subjects, with a mean age of 16.45 ± 0.96 years and with limited hamstring flexibility (defined as 20° loss of knee extension measured with the thigh held at 90° of hip flexion) were recruited for this study. Measurements: Hamstring flexibility was measured using the passive 90/90 test before and after the 6-week program. Results: Differences were significant for test and for the test-by-group interaction. Follow-up analysis indicated significant differences between the control group (gain = 1.67°) and both the eccentric-training (gain = 12.79°) and static-stretching (gain = 12.05°) groups. No difference was found between the eccentric and static-stretching groups. Conclusions: The gains achieved in range of motion of knee extension (indicating improvement in hamstring flexibility) with eccentric training were equal to those made by statically stretching the hamstring muscles.

Studies looking at the effect of anti-epileptic medications on sleep microstructure of patients with epilepsy are almost non-existent. The aim of this study was to compare sleep microstructural characteristics of drug-naïve juvenile myoclonic epilepsy (JME) patients with those on valproate (VPA) monotherapy. Three age- (p = 0.287) and gender- (p = 0.766) matched groups (N = 20 in each group): (1) drug-naïve JME (mean age: 21.2 ± 4.06 years; M : F = 9:11); (2) JME on VPA (mean age: 21.85 ± 4.28 years; M : F = 11:9); (3) healthy controls (mean age: 23.2 ± 3.82 years; M : F = 9:11) underwent overnight polysomnography. Scoring and analysis of arousals American Sleep Disorders Association (ASDA, 2002), cyclic alternating pattern (CAP) (Terzano et al., 2002) parameters were performed. Comparison of arousal and CAP parameters was performed using one-way ANOVA, followed by pairwise comparisons using Fisher's LSD test (p ≤ 0.05). Rapid eye movement (REM) arousal indices were higher in JME patients (Group 1 [p = 0.002] and Group 2 [p <0.001]), whereas the overall and NREM arousal indices were comparable between the three groups. CAP rate was higher in JME patients as compared to controls (p <0.001). Duration of phase A and its subtypes (p <0.001) was reduced in drug-naïve patients as compared to VPA group and controls. Finally, percentage of phase A1 (p = 0.003) was decreased and A3 (p = 0.045) was increased in drug-naïve patients as compared to VPA group and controls. We found significant alterations in REM arousal indices and several CAP parameters in JME patients. However, many of these alterations were not seen in the valproate group. This might indicate that anti-epileptic medications such as valproate may beneficially modulate arousal instability in JME patients, and hence promote sleep quality and continuity.

Ethanol has been known to affect various behavioral parameters in experimental animals, even several hours after ethanol (EtOH) is absent from blood circulation, in the period known as hangover. The aim of this study was to assess the effects of acute ethanol hangover on motor performance in association with the brain cortex energetic metabolism. Evaluation of motor performance and brain cortex mitochondrial function during alcohol hangover was performed in mice 6 hours after a high ethanol dose (hangover onset). Animals were injected i.p. either with saline (control group) or with ethanol (3.8 g/kg BW) (hangover group). Ethanol hangover group showed a bad motor performance compared with control animals (p < .05). Oxygen uptake in brain cortex mitochondria from hangover animals showed a 34% decrease in the respiratory control rate as compared with the control group. Mitochondrial complex activities were decreased being the complex I-III the less affected by the hangover condition; complex II-III was markedly decreased by ethanol hangover showing 50% less activity than controls. Complex IV was 42% decreased as compared with control animals. Hydrogen peroxide production was 51% increased in brain cortex mitochondria from the hangover group, as compared with the control animals. Quantification of the mitochondrial transmembrane potential indicated that ethanol injected animals presented 17% less ability to maintain the polarized condition as compared with controls. These results indicate that a clear decrease in proton motive force occurs in brain cortex mitochondria during hangover conditions. We can conclude that a decreased motor performance observed in the hangover group of animals could be associated with brain cortex mitochondrial dysfunction and the resulting impairment of its energetic metabolism.

Previous studies have demonstrated the relationship between ageing and oxidative stress. In this study, we examined the effects of topical application of a dentifrice containing anti-oxidative, anti-inflammatory, and anti-bacterial agents (Tomarina®) to the gingival surface on gingival collagen degradation in rats. Fischer 344 male rats (4 or 8 months old) were divided into two groups: experimental group and control group. Tomarina® (the experimental group) or control dentifrice (the control group) was applied 5 days per week for 2 months. In the control group, gingival collagen density decreased with ageing. In the experimental group, the collagen density did not change with ageing, and was greater than that in the control group at 10 months of age (p < 0.0083). In addition, the control group showed an increase in serum oxidative stress with ageing. The experimental group also showed increased serum oxidative stress, but the value was lower than the control group at 10 months of age (p < 0.0083). Furthermore, low expressions of protein oxidative damage in the periodontal tissue were observed in the experimental group, compared to the control group at 6 months and 10 months. These findings indicate that Tomarina® might suppress the effects of ageing on gingival collagen degradation, by decreasing oxidative stress in the rat model.

In the present study, we studied the mechanism of mitochondrial ATP-sensitive potassium (mitoKATP) channels regulating hypoxia-inducible factor (HIF)-1α/microRNA (miR)-210/mitochondrial iron-sulfur protein integrin (ISCU) signaling axis and forming a positive feedback loop in chronic hypoxia-induced pulmonary arterial hypertension (PAH) by using in vivo animal model. Two hundred healthy adult SPF Sprague-Dawley rats were randomly divided into five groups: Control, a mimic miR-210 agent (mimic-210) intervention, a miR-210 inhibitor (anti-210) intervention, a chronic PAH and an anti-210 intervention PAH groups, with 40 rats in each group. After the chronic PAH rat model was successfully established, the rats were intervened with mimic-210 and anti-210. The pulmonary artery smooth muscle cells (PASMCs) of rats in each group were acutely isolated and the activity of mitoKATP and mitochondria-derived oxygen free radicals reactive oxygen species (ROS) was detected. RT-qPCR was used to detect the gene of HIF-1α/miR-210/ISCU and western blot analysis was used to detect the protein of HIF-1α and ISCU. The gene and protein expression were detected again after mitoKATP-specific opener diazoxide and blocker 5-HD was given via tail vein and took effect on each group of rats, respectively. Additionally, the indicators were detected again after ISCU recombinant protein was given via tail vein and ISCU small interfering RNA (siRNA) via nasal feeding and took effect on each group of rats, respectively. It was found that the activity of mitoKATP and ROS and the gene and protein levels of HIF-1α/miR-210/ISCU of the mimic-210 group were significantly higher than those of the control group while that of the anti-210 group was significantly reduced (P<0.05). The indicators in the chronic PAH group were significantly higher than those of the control group while those of the anti-210 intervention PAH group were significantly reduced (P<0.05). The indicators of all the groups were increased after being given mitoKATP specific opener diazoxide. The indicators of all the groups were significantly reduced after receiving blocker 5-HD (P<0.05). The indicators of all the groups were significantly reduced after given ISCU recombinant protein. The indicators of all the groups increased following ISCU siRNA, and there was a statistically significant difference (P<0.05). In conclusion, the mechanism of mitoKATP regulating the HIF-1α/miR-210/ISCU signaling axis and formation of a positive feedback loop exists in the PAH rat model.

2013-03-01

We previously showed that impulse oscillometry (IOS) indices of peripheral airway function are associated with asthma control in children. However, little data exist on whether dysfunction in the peripheral airways can predict loss of asthma control. We sought to determine the utility of peripheral airway impairment, as measured by IOS, in predicting loss of asthma control in children. Fifty-four children (age, 7-17 years) with controlled asthma were enrolled in the study. Spirometric and IOS indices of airway function were obtained at baseline and at a follow-up visit 8 to 12 weeks later. Physicians who were blinded to the IOS measurements assessed asthma control (National Asthma Education and Prevention Program guidelines) on both visits and prescribed no medication change between visits. Thirty-eight (70%) patients maintained asthma control between 2 visits (group C-C), and 16 patients had asthma that became uncontrolled on the follow-up visit (group C-UC). There was no difference in baseline spirometric results between the C-C and C-UC groups, except for FEV1/forced vital capacity ratio (86% vs 82%, respectively; P < .01). Baseline IOS results, including resistance of the respiratory system at 5 Hz (R5; 6.4 vs 4.3 cm H2O · L(-1) · s), frequency dependence of resistance (difference of R5 and resistance of the respiratory system at 20 Hz [R5-20]; 2.0 vs 0.7 cm H2O · L(-1) · s), and reactance area (13.1 vs 4.1 cm H2O · L(-1)), of group C-UC were significantly higher than those of group C-C (P < .01). Receiver operating characteristic analysis showed baseline R5-20 and reactance area effectively predicted asthma control status at the follow-up visit (area under the curve, 0.91 and 0.90). Children with controlled asthma who have increased peripheral airway IOS indices are at risk of losing asthma control. Copyright © 2012 American Academy of Allergy, Asthma & Immunology.

To determine whether the frequency and duration of the periods of suppression of a percept in a binocular rivalry (BR) task can be used to distinguish between participants with ADHD and controls. A total of 122 participants (6-15 years) were assigned to three groups: ADHD-Combined (ADHD-C), ADHD-Predominantly Inattentive (ADHD-I), and controls. They each performed a BR task and two measures were recorded: alternation rate and duration of exclusive dominance periods. ADHD-C group presented fewer alternations and showed greater variability than did the control group; results for the ADHD-I group being intermediate between the two. The duration of dominance periods showed a differential profile: In control group, it remained stable over time, whereas in the clinical groups, it decreased logarithmically as the task progressed. The differences between groups in relation to the BR indicators can be attributed to the activity of involuntary inhibition. © The Author(s) 2013.

Reducing juvenile recidivism with cognitive training and a cell phone follow-up: an evaluation of the realvictory program.

Burraston, Bert O; Cherrington, David J; Bahr, Stephen J

2012-02-01

The purpose of this research was to evaluate the effects of a cognitive training and cell phone intervention on the recidivism of 70 juvenile offenders. Median days to rearrest were 106 for the control group, 191 for the class-only group, and 278 for the class plus cell phone group. Using rearrest as the survival criterion, the survival ratios of the class-only and class plus cell phone groups were 2.64 and 2.94 times longer than the control group, respectively. After controlling for gender, prior arrests, and risk score, the Poisson regression indicated that the class-only and class plus cell phone groups were 51% lower in total arrests than the control group. These results suggest that cognitive training supplemented with a cell phone coach is an effective and cost-efficient intervention for reducing recidivism.

INFLUENCE OF INJURY ON DYNAMIC POSTURAL CONTROL IN RUNNERS.

Injury has been linked with altered postural control in active populations. The association between running injury and dynamic postural control has not been examined. The purpose of this study was to examine dynamic postural control in injured and uninjured runners using the Star Excursion Balance Test (SEBT), Time to Stabilization (TTS) of ground reaction forces following a single-leg landing, and postural stability indices reflecting the fluctuations in GRFs during single-leg landing and stabilization tasks (forward and lateral hop). It was hypothesized that dynamic postural control differences would exist between runners with a history of injury that interrupted training for ≥7 days (INJ) when compared to runners without injury (CON). Case-control study. Twenty-two INJ (14 F, 8 M; 23.7 ± 2.1 y; 22.3 ± 2.8 kg/m2; 29.5 ± 16.3 mi/wk) currently running > 50% pre-injury mileage without pain were compared with twenty-two matched CON (14F, 8M; 22.7 ± 1.2 y; 22.7 ± 2.7 kg/m2; 31.2 ± 19.6 mi/wk). INJ group was stratified by site of injury into two groups (Hip/Thigh/Knee and Lower Leg/Ankle/Foot) for secondary analysis. Leg length-normalized anterior, posterolateral, and posteromedial reach distances on the SEBT, medial/lateral and anterior/posterior ground reaction force TTS, directional postural stability indices, and a composite dynamic postural stability index (DPSI), were assessed using mixed model ANOVA (α=0.05) and effect sizes (d). No group X direction interaction or group differences were observed for the SEBT (p=0.51, 0.71) or TTS (p=0.83, 0.72) measures. A group X direction interaction was found for postural stability indices during the forward landing task (p<0.01). Both Hip/Thigh/Knee and Lower leg/Ankle/Foot INJ groups demonstrated a greater vertical postural stability index (VPSI) (p=0.01 for both, d=0.80, 0.95) and DPSI (p=0.01, 0.02, d=0.75, 0.93) when compared to CON suggesting impaired balance control. A group X direction interaction was also found for postural stability indices during the lateral landing task (p=0.03). Only the Hip/Thigh/Knee INJ runners displayed a greater VPSI (p=0.01, d=0.91) and DPSI (p=0.017, d=0.89) when compared to CON. When compared to CON, INJ runners demonstrated impaired dynamic control of vertical forces when performing the single leg landing and stabilization tasks. Clinicians should consider addressing dynamic control of vertical loads through functional tasks during the rehabilitation of running injury. Level 3.

The tibial tubercle deviation associated with recurrent patellar dislocation (RPD) has not been studied sufficiently. New methods of evaluation were used to verify the extent of tubercle deviation in a group with patellar dislocation compared with that in a control group, the frequency of patients who demonstrated a cutoff value indicating that tubercle transfer was warranted on the basis of the control group distribution, and the validity of these methods of evaluation for diagnosing RPD. Sixty-six patients with a history of patellar dislocation (single in 19 [SPD group] and recurrent in 47 [RPD group]) and 66 age and sex-matched controls were analyzed with the use of computed tomography (CT). The tibial tubercle-posterior cruciate ligament (TT-PCL) distance, TT-PCL ratio, and tibial tubercle lateralization (TTL) in the SPD and RPD groups were compared with those in the control group. Cutoff values to warrant 10 mm of transfer were based on either the minimum or -2SD (2 standard deviations below the mean) value in the control group, and the prevalences of patients in the RPD group with measurements above these cutoff values were calculated. The area under the curve (AUC) in receiver operating characteristic (ROC) curve analysis was used to assess the effectiveness of the measurements as predictors of RPD. The mean TT-PCL distance, TT-PCL ratio, and TTL were all significantly greater in the RPD group than in the control group. The numbers of patients in the RPD group who satisfied the cutoff criteria when they were based on the minimum TT-PCL distance, TT-PCL ratio, and TTL in the control group were 11 (23%), 7 (15%), and 6 (13%), respectively. When the cutoff values were based on the -2SD values in the control group, the numbers of patients were 8 (17%), 6 (13%), and 0, respectively. The AUC of the ROC curve for TT-PCL distance, TT-PCL ratio, and TTL was 0.66, 0.72, and 0.72, respectively. The extent of TTL in the RPD group was not substantial, and the percentages of patients for whom 10 mm of medial transfer was indicated were small. Prognostic Level III.

to determine the effectiveness of a health information package in terms of empowering the pregnant women to modify their health-care behaviour and take appropriate action to combat anaemia in pregnancy. the study was conceptualized based on Rosenstock and Becker's health belief model. A quasi-experimental pretest-posttest control group design was used. The sample consists of 225 anaemic pregnant women randomly allocated in experimental (n=75), control group A (n=75) and control group B (n=75). The health seeking behaviour outcome measure included knowledge regarding anaemia, food selection ability, increase in haemoglobin level and compliance to iron supplementation. Intervention was a validated planned educational programme with visual aids and iron supplementation. the results show the mean gain of knowledge scores of experimental group was comparatively higher and control groups A and B showed that F ratio was (F(2,190)=11.910, p<0.01) indicating that the pregnant women learned more about anaemia prevention than others. With regard to food selection ability scores of experimental, control groups A and B the F ratio was also significant (F(2,190)=20.92, p<0.01). Nearly 61.2% of the subjects in experimental group became non-anaemic after the intervention when compared to control group A. This indicated that inspite of iron supplementation received by the three groups health education contributed significantly in modifying their health seeking behaviour and their perception about significance of anaemia has a problem. developing countries still face the critical problem of anaemia in pregnancy. These are the socio-cultural priority problems that demand immediate attention by the policy makers and health professionals. The national anaemia control programme focuses on iron supplementation, but nutritional education and supervision of iron supplementation has failed in different regions. The study implies that economic empowerment; strengthening health literacy through planned educational programs will definitely improve the health behaviour of individual and community at large.

2016-03-01

Young adult cancer survivors have a number of increased health and psychosocial risks. To minimize these risks, they must address any modifiable risk factors, for example increase their physical activity (PA) and reduce stress. Unfortunately, more than half of young survivors remain sedentary, and few participate in a structured form of relaxation. This study evaluated the feasibility, acceptability, and effects of a theory-based PA and meditation intervention for young survivors. Young adult cancer survivors (age 18-39 years) were randomized to receive the 12-week "RElaxation aNd Exercise for Wellness" (RENEW) intervention right away (intervention group) or after a 12-week wait (control group). Participants were assessed at baseline, 12 weeks, and 24 weeks. Thirty-five survivors were enrolled and randomized. Results indicate that 89% of intervention calls were delivered, and most participants felt that intervention goals and the number and duration of intervention calls were appropriate. Satisfaction ratings indicate that the intervention was acceptable, and 100% of participants would recommend it to others. Comparison of the intervention and control groups at the 12-week assessment (i.e., before controls received the intervention) revealed that the intervention group was performing more minutes of at least moderate intensity PA/week (p = 0.002; M = 113.8, SE = 23.5 vs. M = -8.7, SE = 27.1) and outperformed controls on a test of cardiovascular fitness (p = 0.008; M = -1.76, SE = 0.41 vs. M = -0.03, SE = 0.45). When data from the intervention and control groups were pooled, pre- to post-intervention analyses indicated a trend toward improved mood. This theory-based intervention for young adult cancer survivors was feasible and acceptable, and may have helped survivors increase PA, improve fitness, and enhance mood.

In recent years, armed conflicts in the Middle East have resulted in high rates of exposure to traumatic events. Despite the increasing demand of mental health care provision, ongoing violence limits conventional approaches of mental health care provision. Internet-based interventions for posttraumatic stress disorder (PTSD) have proved feasible and effective in Western countries, but their applicability and efficacy in war and conflict regions remains unknown. This study investigated the efficacy of a cognitive behavioral Internet-based intervention for war-traumatized Arab patients, with focus on Iraq. A total of 159 individuals with PTSD participated in a parallel group randomized trial. Participants were randomly allocated by a computer-generated sequence to a treatment group (n=79) or a waiting list control group (n=80). The treatment group received 2 weekly 45-minute cognitive behavioral interventions via Internet over a 5-week period (10 sessions in total). The primary outcome was recovery from posttraumatic stress symptoms. Posttraumatic stress symptoms were significantly reduced from baseline to posttreatment (intention-to-treat analysis) in the treatment group relative to the control group (F1,157=44.29, P<.001, d=0.92). Treatment effects were sustained at 3-month follow-up. Completer analysis indicated that 29 of 47 patients (62%) in the treatment group had recovered from posttraumatic stress symptoms at posttreatment (reliable change and Posttraumatic Stress Diagnostic Scale score <20) versus 1 patient (2%) in the control group (OR 74.19, 95% CI 9.93-585.8, P<.001) indicating that the chance of recovering was 74.19 times higher in the treatment than in the control group. The results indicate, even in unstable and insecure settings with ongoing exposure to human rights violations through war and dictatorships, people with posttraumatic stress symptoms benefit from a cognitive behavioral treatment provided entirely through the Internet. This method of delivery could improve patients' access to humanitarian aid in the form of e-mental health services.

Aim. The aim of this study was to evaluate the presence of the cytokines tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in human periapical lesions. Subjects and methods. Samples were obtained from three groups of teeth: symptomatic teeth, asymptomatic lesions, and uninflamed periradicular tissues as a control. Results. TNF-alpha levels were significantly increased in symptomatic lesions compared to control. Group with asymptomatic lesions had significantly higher concentrations compared to control. There were no significant differences in TNF-alpha levels between symptomatic and asymptomatic lesions. In group with symptomatic lesions, IL-6 levels were significantly higher than in group with asymptomatic lesions. The IL-6 levels in symptomatic group also showed significantly higher concentration in comparison with control group. In asymptomatic group, the IL-6 level had significantly higher concentrations compared to control. Conclusion. These results indicate that symptomatic lesions represent an immunologically active stage of disease, and asymptomatic lesions are the point from which the process advances toward healing.

Behavioral training in neurofeedback has proven to be an essential complement to generalize the effects of pharmacological support in subjects who have attention deficit with hyperactivity disorder (ADHD). Therefore, this investigation attempts to analyze the efficacy of neurofeedback compared with pharmacological support and the combination of both. Participants were 131 students, classified into four groups: control (did not receive neurofeedback or pharmacological support), neurofeedback group, pharmacological support group, and combined group (neurofeedback + pharmacological support). Participants' executive control and cortical activation were assessed before and after treatment. Results indicate that the combined group obtained more benefits and that the neurofeedback group improved to a greater extent in executive control than the pharmacological support group. It is concluded that this kind of training may be an alternative to stimulate activation in subjects with ADHD.

Aloe vera has been used worldwide in pharmaceutical, food and cosmetic industries due to the plethora of biological activities of its constituents. This study was done to evaluate the effects of dietary aloe vera on growth and lipid peroxidation in rainbow trout (Oncorhynchus mykiss). A total number of 480 O. mykiss (mean weight 9.50 ± 0.85 g) were randomized into four experimental groups including one control and three experimental groups that aloe vera was incorporated in their diet at 0.5, 1.0 and 2.0 g kg-1. Trial was done for eight weeks. Then biometry and blood sampling were done. Plasma malondialdehyde, ferric reducing ability of plasma and growth index were estimated at the end of study. The results showed that aloe vera extract did not affect growth indices. Malondialdehyde was increased in the experimental group compared to the control group but ferric reducing ability of plasma showed a decrease in experimental groups (p < 0.05) compared to the control group. Our findings showed that dietary aloe vera have adverse effects on antioxidant defense system in O. mykiss. PMID:25992253

Functional brain response to food images in successful adolescent weight losers compared with normal-weight and overweight controls.

Jensen, Chad D; Kirwan, C Brock

2015-03-01

Research conducted with adults suggests that successful weight losers demonstrate greater activation in brain regions associated with executive control in response to viewing high-energy foods. No previous studies have examined these associations in adolescents. Functional neuroimaging was used to assess brain response to food images among groups of overweight (OW), normal-weight (NW), and successful weight-losing (SWL) adolescents. Eleven SWL, 12 NW, and 11 OW participants underwent functional magnetic resonance imaging while viewing images of high- and low-energy foods. When viewing high-energy food images, SWLs demonstrated greater activation in the dorsolateral prefrontal cortex (DLPFC) compared with OW and NW controls. Compared with NW and SWL groups, OW individuals demonstrated greater activation in the ventral striatum and anterior cingulate in response to food images. Adolescent SWLs demonstrated greater neural activation in the DLPFC compared with OW/NW controls when viewing high-energy food stimuli, which may indicate enhanced executive control. OW individuals' brain responses to food stimuli may indicate greater reward incentive processes than either SWL or NW groups. © 2015 The Obesity Society.

Differences in the types and percentages of essential amino acids (EAAs) in food could influence the value of protein consumed and proteins with a high content of EAAs are the most important components of poultry meat. The use of probiotics for meat and carcass quality improvement has been questioned, while feed supplementation with thyme essential oil (TEO) could be considered as useful natural supplement to be applied in the poultry industry to improve meat quality. Day-old broilers Ross 308 (n = 400) were randomly divided into four groups based on the feed supplement as follows: control, probiotics 0.05%, TEO 0.05% and combination of probiotics and TEO, while the fattening period was 42 days. Six birds of both sexes from each group were selected as a sample, slaughtered and then stored (-18°C) for 6 months till the analysis. The muscular homogeneous sample (50 g) from the breast and thigh of each sample bird was analysed by the Fourier Transform Infrared Spectroscopy method using the device Nicolet 6700. The essential amino acids content was determined and the quality indicators include chemical score, amino acid score, EAA index and biological value were calculated. The obtained results show that for all the tested EAAs of the breast and thigh muscles, the content numerically increased gradually and progressively within the groups as the control scored the minimum followed by the probiotics group, then the combination group and finally the TEO group which scored the highest results. It can be concluded that the TEO promoted the increase of all the EAAs and consequently the quality indicators with significant different compared with the control group and significantly different for some EAAs and quality indicators compared with the probiotics group and the combination group.

Nasal packing is an option for bleeding control after endoscopic sinus surgery and septoplasty. Although new packing materials have been developed, patients still suffer from pain and require additional analgesics treatments. In this study, a prospective, randomized, and double-blind controlled trial was designed to evaluate the effect of fentanyl-soaked packing on pain after endoscopic sinus surgery and septoplasty. One hundred fifty-two patients who underwent nasal surgeries due to chronic rhinosinusitis or nasal septal deviation were enrolled in this study. At the end of operation, 50 mcg fentanyl-soaked biodegradable synthetic polyurethane foams packing Nasopore or Merocel were applied to a group of 79 patients, and saline-soaked ones were applied to another group of 73 patients. To evaluate the influence of fentanyl on postoperative nasal pain, patients' conditions were assessed via means of Numeric Rating Scale, patient satisfaction, and Ramsay Sedation Scale. In addition, symptoms of headache or sore throat and any signs of cardiopulmonary-relevant indicators were monitored. The fentanyl group had significantly decreased Numeric Rating Scale and increased patient satisfaction in every operation type for the majority of postoperative time periods ( P < .05) with reduced postoperative headache and sore throat compared to the control group. The fentanyl group showed a higher score on Ramsay Sedation Scale than the control group ( P < .05 in group including endoscopic sinus surgery). There were no significant differences in cardiopulmonary-relevant indicators between the 2 groups ( P > .05). Fentanyl group showed significantly reduced postoperative pain without serious adverse effects. We suggest that topical fentanyl application to nasal packs can be a useful method to reduce pain during the early postoperative period after endoscopic sinus surgery and septoplasty.

This study assessed the effects of a group intervention-Siblings Coping Together (SibCT)-on siblings' and caregivers' anxiety symptoms compared to controls, and potential moderators. Seventy healthy siblings of children on or off treatment (7-16 y old, 41 males) participated in a randomized controlled trial (RCT) with 2 arms/groups: SibCT (n = 41) and an attention control (CG) (n = 34). Both groups had eight 2-hour weekly sessions. EG followed SibCT's educational, social, and problem-solving activities. CG had planned games and crafts. Siblings and caregivers self-reported on anxiety symptoms at baseline, intervention end, and 3 months later. Multivariable mixed model analyses examined the intervention effect over time, and potential moderators (gender, on/off ill child's treatment). No main effects of group or time were found in sibling scores. A group × gender interaction (P < .05) indicated that in the intervention group female siblings reported less total anxiety symptoms than male siblings, with no significant gender differences in the control group. Caregivers' total anxiety symptoms declined over time (P < .02). A group × on/off treatment interaction in physiological/panic subscale (P < .03) indicated that when ill child was on treatment, caregivers of siblings in SibCT reported less anxiety compared with caregivers of CG. There was no clear SibCT intervention effect. SibCT may benefit female siblings, and caregivers whose ill child is on active treatment. Contextual factors (gender) seem to influence psychosocial intervention in this population. Copyright © 2018 John Wiley & Sons, Ltd.

There is no conclusive evidence regarding the effect of fasting on different features in asthmatic patients. In the present study, the effect of Ramadan fasting in asthmatic patients and healthy control was studied. Haematological indices, inflammatory mediators, pulmonary function tests (PFT) and respiratory symptoms were evaluated in 15 asthmatic patients compared to 14 healthy matched control group before and after the one-month fasting period in Ramadan. The change in each parameter from the beginning to the end of Ramadan was calculated and referred to as "variation during Ramadan". The values of MCH, MCHC in both groups and monocyte counts in asthmatic patients, were significantly increased but platelet count was reduced in asthmatic and controls respectively compared to pre-Ramadan fasting period (P<0.05 to 0.001). Serum hs-CRP level in control and asthmatic groups was significantly reduced after Ramadan fasting month (P<0.001 for both groups). PFT values after Ramadan fasting month in both groups were non-significantly higher compared to pre-fasting values except FVC. Respiratory symptoms in asthmatic patients were non-significantly but wheeze-o was significantly reduced after Ramadan fasting period in asthma group (P<0.05). There was no significant difference in variations of different parameters during Ramadan fasting period between two groups, although reduction of hs-CRP in asthmatic group was non-significantly higher than control group. These results show that Ramadan fasting period has no negative impact on asthma and may have some positive effect on asthma severity with regard to reduction of hs-CRP concentration and chest wheeze.

Identifying effective interventions is vitalin preventing slip-induced fall accidents in older adults. The purpose of the current study was to evaluate the efficacy of moveable platform training in improving recovery reactions and reducing fall frequency in older adults. Twenty-four older adults were recruited and randomly assigned to two groups (training and control). Both groups underwent three sessions including baseline slip, training, and transfer of training on a slippery surface. Both groups experienced two slips on a slippery surface, one during the baseline and the other (after two weeks) during the transfer of training session. In the training session, the training group underwent twelve simulated slips using a moveable platform while the control group performed normal walking trials. Kinematic, kinetic, and EMG data were collected during all the sessions. Results indicated a reduced incidence of falls in the training group during the transfer of training trial as compared to the control group. The training group was able to transfer proactive and reactive control strategies learned during training to the second slip trial. The proactive adjustments include increased center-of-mass velocity and transitional acceleration after training. Reactive adjustments include reduction in muscle onset and time to peak activations of knee flexors and ankle plantarflexors, reduced ankle and knee coactivation, reduced slip displacement, and reduced time to peak knee flexion, trunk flexion, and hip flexion velocities. In general, the results indicated a beneficial effect of perturbation training in reducing slip severity and recovery kinematics in healthy older adults. PMID:22134467

Loads with energy storage property can actively participate in power balance for power systems, this paper takes air conditioner as a controllable load example, proposing a multi-load groups coordinated load control strategy considering power network constraints. Firstly, two load control modes considering recovery of load diversity are designed, blocking power oscillation of aggregated air conditioners. As the same time, air conditioner temperature setpoint recovery control strategy is presented to avoid power recovery peak. Considering inherent characteristics of two load control modes, an coordinated load control mode is designed by combining the both. Basing on this, a multi-load groups coordinated load control strategy is proposed. During the implementing of load control, power network constraints should be satisfied. An indice which can reflect the security of power system operating is defined. By minimizing its value through optimization, the change of air conditioning loads’ aggregated power on each load bus can be calculated. Simulations are conducted on an air conditioners group and New England 10-generator 39-bus system, verifying the effectiveness of the proposed multi-load groups coordinated load control strategy considering power network constraints.

Ageing is a natural phenomenon that has tremendous amount of control over normal physiological functions. Diabetes mellitus and ageing share common symptoms like stiffness and loss of functioning of tissues due to cross-liked proteins and free radicals. Glycated Haemoglobin (HbA1c) is often used as a stable cumulative index of glycemic control and has shown that even in non-diabetic adults, there is a steady increase in HbA1c levels with age. Aim of the study is to evaluate the strength of association of HbA1c with metabolic and cardiovascular ageing indices in subjects between the age group of 40 to 60 yrs. A total of 220 subjects, with (n=110) and without (n=110) diabetes were assessed for the metabolic and cardiovascular ageing indices. BMI, waist hip ratio, fat percentage, Fasting blood sugar and HbA1c were assessed as metabolic ageing indices. The cardiovascular ageing indices measured were resting heart rate, blood pressure and heart rate variability. Ageing indices were compared between subjects with and without diabetes using independent' t' test and showed that the T2DM group exhibit significant accelerated ageing as compared to that of the controls. Pearson's and partial correlation coefficient was used to assess the association of HbA1c with the ageing indices without and with controlling for chronological age, indicated that, strength of association of levels of HBA1c with cardiovascular and other metabolic indices of ageing is statistically significant. The study concludes that the tightness of glycemic control has a significant impact on the biological ageing process.

[The European countries confronting cancer: a set of indicators assessing public health status].

Borella, Laurent

2008-11-01

We now know that efficient public policies for cancer control need to be global and take into account each and all the factors involved: economics and level of development, style of life and risk factors, access to screening, effectiveness of the care-providing system. A very simple scorecard is proposed, based on publicized public health indicators, which allows a comparison between European countries. We extracted 49 indicators from public databases and literature concerning 22 European countries. We made correlation calculations in order to identify relevant indicators from which a global score was extracted. Using a hierarchical clustering method we were then able to identify subsets of homogeneous countries. A 7 indicator scorecard was drawn up: national gross product, scientific production, smoking rate, breast screening participating rate, all cancer mortality rate (male population), 5 years relative survival for colorectal cancer and life expectancy at birth. A global score shows: 1) the better positioned countries: Switzerland, Sweden, Finland and France; 2) the countries where cancer control is less effective: Estonia, Hungary, Poland and Slovakia. Three subsets of countries with a fairly similar profile were identified: a high level of means and results group; a high level of means but a medium level of results group; and a low level of means and results group. This work emphasizes dramatically heterogeneous situations between countries. A follow-up, using a reduced but regularly updated set of public health indicators, would help induce an active European policy for cancer control.

To study the clinical effects of Shen-nourishing and menstruation-regulating method (SNMRM) combined with Triptorelin Acetate Injection (TAI) on patients with luteinized unruptured follicle syndrome (LUFS). Sixty-two LUFS patients were randomly assigned to the treatment group and the control group. TAI was given to patients in the control group while SNMRM + TAI was given to those in the treatment group. The ovulation rate and the pregnancy rate were observed in the two groups. The ovulation rate in the treatment group was higher than that in the control group, but without significant difference (85.53% versus 79.07%, P > 0.05). The pregnancy rate was significantly higher in the treatment group than in the control group (56.25% vs 30.00%, P < 0.05). Treatment of LUFS by SNMRM + TAI could improve the ovulation rate and the pregnancy rate, indicating that LUFS patients' ovary functions could be improved by using different menstruation regulating methods during different follicular development phases.

Niemann-Pick disease type C is a clinically heterogeneous storage disorder with an unknown primary metabolic defect. We have undertaken somatic cell hybridisation experiments using skin fibroblast strains from 12 patients representing a wide clinical spectrum. Preliminary experiments using filipin staining of free cholesterol as a marker for complementation indicated the existence of one major group (group alpha) and one minor group (group beta) represented by one mutant strain. Subsequent experiments in which sphingomyelinase activity was measured as a marker for complementation using five mutant strains showing activity consistently < 40% control levels confirmed the existence of the second group.

Utilizing relevance theory, this study investigated the ability of children with Asperger syndrome (AS) and high-functioning autism (HFA) to use context when answering questions and when giving explanations for their correct answers. Three groups participated in this study: younger AS/HFA group (age 7-9, n=16), older AS/HFA group (age 10-12, n=23) and a normally functioning control group (age 7-9, n=23). The results indicated that the younger AS/HFA group did less well when answering contextually demanding questions compared to the control group, and the performance of the older AS/HFA group fell in between the younger AS/HFA group and the control group. Both AS/HFA groups had difficulties explaining their correct answers, suggesting that they are not always aware of how they have derived answers from the context.

Depression is often characterized by attentional biases toward negative items and away from positive items, which likely affects reward and punishment processing. Recent work has reported that training attention away from negative stimuli reduced this bias and reduced depressive symptoms. However, the effect of attention training on subsequent learning has yet to be explored. In the present study, participants were required to learn to maximize reward during decision making. Undergraduates with elevated self-reported depressive symptoms received attention training toward positive stimuli prior to performing the decision-making task (n = 20; active training). The active-training group was compared to two other groups: undergraduates with elevated self-reported depressive symptoms who received placebo training (n = 22; placebo training) and a control group with low levels of depressive symptoms (n = 33; nondepressive control). The placebo-training depressive group performed worse and switched between options more than did the nondepressive controls on the reward maximization task. However, depressives that received active training performed as well as the nondepressive controls. Computational modeling indicated that the placebo-trained group learned more from negative than from positive prediction errors, leading to more frequent switching. The nondepressive control and active-training depressive groups showed similar learning from positive and negative prediction errors, leading to less-frequent switching and better performance. Our results indicate that individuals with elevated depressive symptoms are impaired at reward maximization, but that the deficit can be improved with attention training toward positive stimuli.

BACKGROUND: Prehypertension is considered as a cardiovascular disease predicator. Management of prehypertension is an appropriate objective for clinicians in a wide range of medical centers. Treatment of prehypertension is primarily non-pharmacological, one of which is massage therapy that is used to control the blood pressure. This study aimed to evaluate the effect of Swedish massage (face, neck, shoulders and chest) on blood pressure (BP) of the women with prehypertension. METHODS: This was a single-blind clinical trial study. Fifty prehypertensive women selected by simple random sampling which divided into control and test groups. The test group (25 patients) received Swedish massage 10-15 min, three times a week for 10 sessions and the control groups (25 patients) also were relaxed at the same environment with receiving no massage. Their BP was measured before and after each session. Analyzing the data was done using descriptive and inferential statistical methods (chi square, Mann-Whitney, paired t-test and student t-test) through SPSS software. RESULTS: The results indicated that mean systolic and diastolic blood pressure in the massage group was significantly lower in comparison with the control group (p < 0.001). CONCLUSIONS: Findings of the study indicated that massage therapy was a safe, effective, applicable and cost-effective intervention in controlling BP of the prehypertension women and it can be used in the health care centers and even at home.

Attention deficit hyperactivity disorder (ADHD) is the most common behavioral problem during childhood and in school-aged children. Various projection drawings have been designed for assessing children's personality and psychological disorders including the tests of draw a person (DAP) and draw a family (DAF). We aimed to compare the differences between typically developing children and children with ADHD using these tests. In this case-control study, all the 9-10 year-old boy students studying at the third and fourth grades were enrolled from schools in the 2nd educational district of Shiraz, south of Iran. Eighty students were then selected and enrolled into the ADHD group and the control group. The Diagnostic and Statistical Manual of Mental Disorders, 4th edition- text Revised (DSM-IV-TR), and the Child Symptoms Inventory were used to diagnose the children with ADHD. We evaluated and analyzed impulsiveness, non-impulsiveness, emotional problems and incompatibility indices in the DAP and DAF tests in each group. A significant difference was found in the indices of incompatibility and emotional problems, impulsiveness, non-impulsiveness and DAF between typically developing children and those with ADHD. The mean (±SD) total scores of the above mentioned indices in the ADHD group were 19.79(±2.94), 12.31(±1.84), 5.26(±2.29) and 5.89(±2.13), respectively (P<0.001). The corresponding figures for these indices in the normal group were 12.11(±4.74), 5.63(±2), 10.36± (2.33) and 2.88(±2.13), respectively (P<0.001). Significant differences were obtained between the control group and children with ADHD using these two drawing tests. The rate of impulsivity and emotional problems indices in drawings of children with ADHD was markedly more common than those of the typically developing children. This suggests the need for further assessment to screen ADHD.

Previous reports have indicated that formation and eruption of the maxillary teeth, especially the molars, are delayed in skeletal Class III patients compared with Class I and Class II patients. However, the relationship between the formation/eruption of maxillary teeth and the skeletal pattern of the maxilla is not yet clear. To examine this relationship, we studied 81 skeletal Class III Japanese patients (mean age, 8.8 years). The sample was divided into 2 groups: a maxillary retrusion (MR) group, characterized by a small SNA angle and a short palatal length, and a control group in which those values were in the normal range for patients of Japanese descent. There was no significant difference in the rate of formation for the maxillary and mandibular teeth between the 2 groups. The eruption of the maxillary second molars was delayed in the MR group compared with the control group. There were no significant differences between the 2 groups for any other teeth. A multiple-regression analysis was carried out to examine whether the skeletal pattern of the maxilla is a useful indicator for predicting the eruption of the maxillary teeth. The results showed that palatal length and chronologic age were significant independent (explanatory) variables for predicting eruption of the maxillary second molars. These findings indicated that the skeletal pattern of the maxilla is a useful indicator for predicting the timing of maxillary molar eruption when considering treatment of skeletal Class III malocclusions.

To examine the performance on the Deese-Roediger-McDermott task of adults divided into ADHD subtypes and compares their performance to that of healthy controls to examine whether adults with ADHD are more susceptible to the production of false memories under experimental conditions. A total of 128 adults with ADHD (50% females), classified into three Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV-TR) subtypes, were compared with 48 controls. The results indicated that the ADHD participants recalled and recognized fewer studied words than the controls, the ADHD groups produced more false memories than the control group, no differences in either the false positives or the false negatives. The ADHD-combined (ADHD-CT) group recognized significantly more critical words than the control, ADHD-predominantly inattentive (ADHD-IA), and ADHD-predominantly hyperactive-impulsive (ADHD-HI) groups. The ADHD groups recalled and recognized more false positives, were more confident in their false responses, and displayed more knowledge corruption than the controls. The ADHD-CT group recalled and recognized more false positives than the other ADHD groups. The adults with ADHD have more false memories than the controls and that false memory formation varied with the ADHD subtypes.

González, Edilberto R; Armas, Luisa

2012-10-01

Following 48 years of successful operation of the National Tuberculosis Control Program, Cuban health authorities have placed tuberculosis elimination on the agenda. To this end some tuberculosis control processes and their indicators need redesigned and new ones introduced, related to: number and proportion of suspected tuberculosis cases among vulnerable population groups; tuberculosis suspects with sputum microscopy and culture results useful for diagnosis (interpretable); and number of identified contacts of reported tuberculosis cases who were fully investigated. Such new indicators have been validated and successfully implemented in all provinces (2011-12) and are in the approval pipeline for generalized use in the National Tuberculosis Control Program. These indicators complement existing criteria for quality of case detection and support more comprehensive program performance assessment.

To investigate the therapeutic effect of the compound Danshen dripping pill combined with laser acupoint irradiation on early diabetic retinopathy, 19 patients with early diabetic retinopathy were randomly divided into a treatment group and a control group. The TaiYang, YangBai, YuYao and ZanZhu acupoints of patients in the treatment group were irradiated with a semiconductor laser combined with the oral compound Danshen dropping pills, while those in the control group only used the oral compound Danshen dropping pills. The indicators of vision, mean defect of light sensitivity in the visual field, renal function and fasting blood glucose, were examined to evaluate the efficacy. After treatment, the above indicators of patients in the two groups were significantly improved and there was a significant difference between the two groups. This showed that the compound Danshen dripping pills combined with the laser acupoint irradiation can improve the ischemic and anoxic state of early diabetic retinopathy and improve the visual field.

The purpose of this study was to address the need for effective educational interventions to promote students' clinical decision making (CDM) within clinical practice environments. Researchers used a quasi-experimental, non-equivalent groups, posttest-only design to assess differences in CDM ability between intervention group students who participated in analogy-guided learning activities and control group students who participated in traditional activities. For the intervention, analogy-guided learning activities were incorporated into weekly group discussions, reflective journal writing, and questioning with clinical faculty. The researcher-designed Assessment of Clinical Decision Making Rubric was used to assess indicators of CDM ability in all students' reflective journal entries. Results indicated that the intervention group demonstrated significantly higher levels of CDM ability in their journals compared with the control group (ES(sm) = 0.52). Recommendations provide nurse educators with strategies to maximize students' development of CDM ability, better preparing students for the demands they face when they enter the profession.

Oncologic transoral robotic surgery (TORS) requires in most cases the concurrent or staged surgical treatment of the regional lymph nodes in the neck as well. The purpose of this study was to determine whether the timing of the regional lymphadenectomy (neck dissection) has an impact on the surgical outcomes and on the complication rates. Single-institution, prospective case series with internal control group. Twenty-one patients underwent TORS and appropriate neck dissection concurrently (control group), while 20 patients underwent neck dissection in a timely staged fashion, 8.4 days (median; range, 3-28 days) following their TORS procedure (experimental group). Outcome measures included nodal yield, intraoperative pharyngocervical fistula formation, postoperative fistula formation, postoperative bleeding from the primary and from the neck dissection site, haematoma, seroma, and infection. Nodal yield values, as the oncologic quality indicator of a neck dissection, were comparable in the experimental and in the control group. Complication rates did not differ between the groups: intraoperative and postoperative fistula formation, postoperative bleeding, haematoma and seroma rates were similarly low in the two groups. There was no infection in either group. In the present cohort of 41 TORS-patients, the timing of neck dissection did not make a significant difference in the outcomes. We suggest therefore that aspiring and established TORS-teams do not restrict their appropriate indications due to robotic slot and theatre time constraints, but perform each indicated TORS-case as soon as possible within their given systems, even if the neck dissections cannot be done on the same day.

2011-01-01

This study investigated the effectiveness of Chinese therapeutic food on female reproductive hormones in a double-blind, placebo-controlled clinical trial. Chinese kiwi fruit extract (Hong En No. 1) was provided for Australian peri-menopausal women for one month. Chinese medical assessment and urinary 2-hydroxyestrone (2-OHE) and 16alpha-hydroxyestrone (16alpha-OHE) tests were conducted. Twenty-six urinary samples (pre and post-trial) which met the requirement of testing were analysed, the ratio 2-OHE:16alpha-OHE of pre-trial (1.18 ± 0.34) and post-trial (0.97 ± 0.29) in the control group (n = 6) decreased but showed no significant change, this ratio of pre-trial (1.44 ± 0.16) and post-trial (1.65 ± 0.21) in the treatment group (n = 7) indicated an improvement (P = 0.066), which results in beneficial hormone regulation. The Chinese medicine assessment indicated that the patterns of disharmony mainly include Liver Qi stagnation and Liver-Kidney Yin deficiency patterns. No significant change observed in the control group, significant score reduction of the patterns of disharmony was achieved at post-trial in the treatment group, which indicates an improvement of general health condition.

The present study aimed to investigate whether bone marrow-derived mesenchymal stem cell (BMSC) sheets combined with titanium implants enhanced implant osseointegration in an ovariectomized (OVX) rat model of osteoporosis. Sprague-Dawley rats were randomly assigned into a test group and control group. Allogenic BMSCs were collected from the rats, cultured and stored via cryopreservation. At 6 months post-ovariectomy, establishment of the OVX model was confirmed by micro-computed tomography (CT) measurements. BMSC sheets were subsequently layered and wrapped over titanium implants for implantation. Unmodified implants served as the control. At 8 weeks post-implantation, samples were observed by micro-CT reconstruction and histomorphometric evaluation. Micro-CT reconstruction identified a marked improvement in the surrounding bone volume following treatment, with data analyses indicating a significant increase in bone volume in the BMSC-implant group compared with the control implant group (P<0.05). In addition, histological staining identified new bone formation and an increased rate of bone-implant contact surrounding the BMSC-implant constructs. These results indicate that the use of BMSC sheets as a novel tissue engineering approach improves the osseointegration of titanium implants in an osteoporosis model. This method may expand the operative indications in patients with osteoporosis and improve the success rate of clinical dental implant treatments. PMID:29250137

The objective of this study was to compare the surgical outcomes of patients operated on, with or without discography prior to operation. The study was designed as a randomized controlled trial, using power analysis with McNemar's test on two correlated proportions. The study comprised of 310 patients divided into trial (207) and control (103) groups. Inclusion criteria were low back pain resistant to nonsurgical treatment for more than 6 months and conventional radiological findings showing degenerative changes without a clear generator of pain. Exclusion criteria were red flags (tumor, trauma, and infection). After standard radiological diagnostic imaging (X-ray, CT, and MR), patients filled in the Oswestry Disability Index (ODI), SF-36, Zung, and MSP questionnaires. Depending on their radiological findings, patients were included and randomly placed in the trial or control group. At the 1-year follow-up examination, patients filled in the ODI, SF-36, and Likert scale questionnaires. The difference between preoperative and postoperative ODI in the control group degenerative disc disease (DDD) subgroup was 22.07 %. The difference between preoperative and postoperative ODI in the trial group DDD subgroup was 35.04 %. Differences between preoperative and postoperative ODI in the control group other indications subgroup was 26.13 %. Differences between preoperative and postoperative ODI in the trial group other indications subgroup was 28.42 %. DDD treated surgically without discography did not reach the clinically significant improvement of 15 ODI points for the patients treated with fusion. Provocative discography screening with psychological testing in the trial group made improvement following fusion clinically significant.

To investigate whether laughter therapy lowers total mood disturbance scores and improves self-esteem scores in patients with cancer. Randomized controlled trial in a radio-oncology outpatient setting. Sixty-two patients were enrolled and randomly assigned to the experimental group (n=33) or the wait list control group (n=29). Three laughter therapy sessions lasting 60 minutes each. Mood state and self-esteem. The intention-to-treat analysis revealed a significant main effect of group: Experimental group participants reported a 14.12-point reduction in total mood disturbance, while the wait list control group showed a 1.21-point reduction (p=0.001). The per-protocol analysis showed a significant main effect of group: The experimental group reported a 18.86-point decrease in total mood disturbance, while controls showed a 0.19-point reduction (p<0.001). The self-esteem of experimental group was significantly greater than that of the wait list control group (p=0.044). These results indicate that laughter therapy can improve mood state and self-esteem and can be a beneficial, noninvasive intervention for patients with cancer in clinical settings.

Persistence of decidual NK cells and KIR genotypes in healthy pregnant and preeclamptic women: a case-control study in the third trimester of gestation

PubMed Central

2011-01-01

Background Natural Killer (NK) cells are the most abundant lymphocytes in the decidua during early gestation. The interactions of NK cells with the extravillous cytotrophoblast have been associated with a normal spiral artery remodeling process, an essential event for a successful pregnancy. Recent data indicate that alterations in the amount of decidual NK (dNK) cells contribute to the development of preeclampsia (PE). Moreover, genetic studies suggest that Killer Immunoglobulin-like Receptors (KIR) expressed in dNK cells influence the susceptibility to PE. Although dNK cells have been well characterized during early pregnancy, they have been scarcely studied in the third trimester of gestation. The aim of this work was to characterize dNK cells at the last trimester of gestation and to analyze the KIR genotype of healthy and PE women. Methods Decidual samples were obtained during Caesarean section from control (n = 10) and PE (n = 9) women. Flow cytometric analysis of CD3, CD56, CD16 and CD9 was used to characterize and quantify dNK cells in both groups. Cell surface markers from decidual leukocytes were compared with PBMC from healthy donors. KIR genotyping was performed in genomic DNA (control, n = 86; PE, n = 90) using PCR-SSP. Results The results indicate that dNK cells persist throughout pregnancy. They represented 20% of total leukocytes in control and PE groups, and they expressed the same cell surface markers (CD3-, CD56+, CD16- and CD9+) as dNK in the first trimester of gestation. There were no significant differences in the percentage of dNK cells between control and PE groups. The analysis of KIR gene frequencies and genotypes was not statistically different between control and PE groups. The ratio of activating to inhibitory genes indicated that the overall inhibitory balance (0.2-0.5) was more frequent in the PE group (control, 31.3% vs PE, 45.5%), and the activating balance (0.6-1.1) was more frequent in the control group (control, 68.6% vs PE, 54.4%). However this difference was not significant. Conclusion We demonstrated the persistence of dNK cells in PE and control women at the third trimester of pregnancy; these dNK cells had a similar phenotype to those found during early pregnancy. The predominance of a KIR inhibitory balance in the PE group could be associated to the physiopathology of PE. PMID:21247496

Research shows that placebo analgesia and nocebo hyperalgesia can be induced through observational learning. Our aim was to replicate and extend these results by studying the influence of the type and colour of stimuli used as placebos on the placebo effects induced by observational learning. Three experimental and two control groups were tested. All participants received pain stimuli of the same intensity preceded by colour lights (green and red) or geometric shapes (circles and squares). Before receiving pain stimuli, participants in the experimental groups, but not in the control groups, observed a model who rated pain stimuli that were preceded by either green lights (green placebo group), red lights (red placebo group), or circles (circle placebo group) as being less painful than those preceded by either red lights (green placebo group), green lights (red placebo group), or squares (circle placebo group). As a result participants in the experimental groups rated pain stimuli preceded by either green lights (green placebo group), red lights (red placebo group), or circles (circle placebo group) as being less painful than the participants in the control groups did, indicating that placebo effect was induced. No statistically significant differences were found in the magnitudes of the placebo effects between the three experimental groups (green placebo, red placebo, and circle placebo groups), indicating that neither the type nor the colour of placebo stimuli affected the placebo effects induced by observational learning. The placebo effects induced by observational learning were found to be unrelated to the individual differences in pain anxiety, fear of pain, and empathy.

Parental divorce affects approximately 30 000 South African children annually. This pilot study aimed to evaluate the effectiveness of the Children of Divorce Intervention Programme (CODIP) at two South African schools. CODIP is a preventively oriented group programme which was developed to foster resilience by helping children cope more effectively with possible academic, behavioural, and emotional problems brought about by their parents' divorce. Twenty-five 10- to 14-year-old boys from two primary schools were randomly assigned to 2 experimental groups and 1 delayed intervention control group. The experimental groups attended 12 one-hour weekly sessions; the control group received no intervention until after the study was completed. Children's understanding of divorce related events and social, emotional and behavioural adjustment was assessed one week before the intervention and three months thereafter using a battery of self-rated, teacher-rated and parent-rated questionnaires. One-way ANOVAs indicated no statistically significant decline in children's self-reported problematic beliefs about divorce or total difficulties. However, teachers' and parents' ratings indicated that compared to the control group, the combined experimental groups showed significant improvement in their general behavioural, emotional and social adjustment after programme participation. The results suggest that South African children who experience parental divorce may benefit from participation in CODIP.

This parallel-group, randomized controlled pilot study examined daily meditation in a diverse sample of older adults with postherpetic neuralgia. Block randomization was used to allocate participants to a treatment group (n = 13) or control group (n = 14). In addition to usual care, the treatment group practiced daily meditation for six weeks. All participants completed questionnaires at enrollment in the study, two weeks later, and six weeks after that, at the study's end. Participants recorded daily pain and fatigue levels in a diary, and treatment participants also noted meditation practice. Results at the 0.10 level indicated improvement in neuropathic, affective, and total pain scores for the treatment group, whereas affective pain worsened for the control group. Participants were able to adhere to the daily diary and meditation requirements in this feasibility pilot study. Copyright © 2015 Elsevier Inc. All rights reserved.

Feelings of romanticism and self-esteem among pregnant adolescents, adolescent mothers, and a control group of nonpregnant, nonparenting adolescents were investigated. The Bachman Self-Esteem Scale (Bachman, O'Malley, & Johnston, 1978) and the Dean Romanticism Scale (Dean, 1961) were distributed to 649 U.S. female adolescents--255 pregnant adolescents, 121 adolescent mothers, and 273 teenagers in the control group. For romanticism, the results indicated a significant main effect for group (pregnant teens, teen mothers, and a control group consisting of nonpregnant, nonparenting teenagers) and ethnicity (White, Hispanic, African American, and Asian) but not for age (13 to 15 years and 16 to 19 years). The pregnant teens and teen mothers thus had a higher degree of romanticism than the control group did. For self-esteem, there was a significant main effect for race, but not for group or for age. This main effect was qualified by a significant interaction between ethnicity and age.

Alexithymia is characterised by difficulties identifying and describing emotions. Few studies have investigated how alexithymia influences decision-making under different conditions (ambiguity and risk). This study aimed to examine whether alexithymia contributes to impairment in decision-making. This study included 42 participants with high scores in the Chinese version of Toronto Alexithymia Scale (alexithymia group), and 44 matched subjects with low scores (control group). Decision-making was measured using the Iowa Gambling Task (IGT) and the Game of Dice Task (GDT). The main findings of this study revealed selective deficits in IGT performance for the alexithymia group, while GDT performance was unimpaired when compared with the control group. In IGT, total netscores were lower for the alexithymia group compared to the control group, particularly with regard to block 5. Moreover, the alexithymia individuals selected significantly more adverse cards than the controls, indicating significant decision-making impairments. Alexithymia selectively influences decision-making under ambiguity.

Enteral nutrition is the best way to feed or supplement the diet when gastrointestinal tract functions of patients are partially or totally preserved. Whenever total enteral nutrition is needed, it represents the only source of nutrients for patients. Thus, it is mandatory to ensure that high biological value proteins are included in enteral formulae. To assess the biological quality of a protein blend constituted by 50% potassium caseinate, 25% whey protein and 25% pea protein intended to be used in enteral nutrition products. Forty Wistar rats (20 male and 20 female), with initial body weight of 51 g, where divided into four groups and feed for 10 days with: casein (Control), experimental protein blend (Experimental), liophylized normo- and hyperproteic enteral nutrition formulae adapted to the animal nutritional requirements (Normoproteic and Hyperproteic). Protein efficiency ratio (PER), apparent digestibility coefficient (ADC), relationship between retained and absorbed nitrogen (R/A) and relationship between retained and consumed nitrogen (R/I) where calculated. Experimental and control groups had similar values for all analysed indices (PER, ADC, R/A and R/I). These indices where also similar between normo and hyperproteic groups, but lower than experimental and control groups, except in PER, where normoproteic group was either similar to control and hiperproteic group. The quality of the protein blend used in this study is high. It is a good protein source to be used in the development of new enteral nutritional products.

Previous research studies have indicated that biofeedback treatment and relaxation techniques are effective in reducing psychological and physical symptoms (Hammond, 2005; Manzoni, G. M., Pagnini, F., Castelnuovo, G., & Molinari, E., 2008). However, dearth of studies has compared heart rate variability (HRV) biofeedback treatment and relaxation training to reduce trait anxiety. The objective of this study was to determine the effect of HRV biofeedback treatment and relaxation training in reducing trait anxiety compared to control group without any treatment using students in a science and engineering university of South Korea. For the present study, a total of 15 graduate students with moderate level of trait anxiety were recruited for 4 individual sessions every two weeks. They were randomly assigned into three groups: biofeedback treatment (n = 5), relaxation training (n = 5), and no treatment control group (n = 5). Our results revealed significant difference in change score of trait anxiety between the HRV biofeedback treatment and the no treatment control group. However, no significant difference was found between the relaxation training group and the no treatment control group. In addition, there was no significant difference between the HRV biofeedback treatment and the relaxation training. Results of the present study indicate that there is potential benefit in utilizing HRV biofeedback treatment for stress management programs and/or anxiety reduction treatment PMID:27099546

Background: Previous studies have indicated that exercise training improves body composition and cardiovascular disease risk factors. The aim of the present study was to investigate the effect of 12 weeks of aerobic, strength and combined training on body composition, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and C-reactive protein (CRP) in sedentary middle-aged men. Methods: Forty-seven male aged 40–60 years voluntarily participated in this study and were divided in four groups: aerobic (n = 12), strength (n = 12), combined (n = 11), and control (n = 12) groups randomly. Body composition, ICAM-1, VCAM-1, and CRP were measured before and after 12 weeks. Data were analyzed using paired t-test and analysis of variance statistical methods. Results: There were significant differences in body weight between aerobic and strength training (P = 0.004) and aerobic and control groups (P = 0.018), body mass index between combined and strength training (P = 0.004) and combined and control groups (P = 0.001), fat percentage between aerobic training and control group (P = 0.017) and combined training and control groups (P = 0.004), and finally, fat-free mass between aerobic and strength training (P = 0.024), aerobic and combined training (P = 0.0001), strength and control groups (P = 0.035), and combined and control groups (P = 0.0001). Conclusions: The results indicated that 12-week workout, 20–60 min/session, 3 days a week of moderate intensity exercise improved body composition, ICAM-1, VCAM-1, and CRP compared to those who did not participate in any training. However, all three types of exercises had small benefits on body composition, ICAM-1, VCAM-1, and CRP in sedentary middle-aged men, and the importance of combined training required further investigations.

This study investigated the effects active learning strategies had on college students' achievement, motivation, and self-efficacy, in a human physiology course for non-majors. A continuum-based active learning instructional model was implemented over the course of a semester to assess the effects on the variables and specific student outcomes of learning mentioned above. In addition analyses were conducted to explore what learner characteristics contributed to the successful implementation of the model such as students' gender, classification, major, grade point average, ACT and SAT scores, motivation, and self-efficacy. A quasi-experimental, Solomon-4 Group design was undertaken on 171 students in a small west-Texas university. Treatment groups were taught using the model while controls were taught using traditional lecture methods. Students were administered a comprehensive physiology content exam, sections of the Motivated Strategies for Learning Questionnaire, and attitude surveys to assess the effects of the continuum-based active learning strategies. Factorial analyses indicated the treatment group acquired significantly more content knowledge and were significantly more self-efficacious than students in the control group. There were no significant differences in motivation. Factorial and modified regression analyses in the aptitude by treatment interaction exploration determined that males in the treatment group performed significantly better on the comprehensive physiology content exam versus males in the control group. While females performed better overall than males, there were no significant differences in achievement between females in the treatment group and those in the control. No significant interactions were found for the other learner characteristics. The results also indicated that students' general cognitive ability as measured by their grade point average, ACT, and SAT scores and their self-efficacy contributed significantly to their achievement. Attitude surveys indicated that students in both the treatment and control groups demonstrated a positive attitude toward active learning, believed it helped them to learn the material, and would choose an active learning course in the future if given the opportunity. This study demonstrated that continuum-based active learning strategies used in this context, improved students' content acquisition and self-efficacy and had wide applicability with a number of learner characteristics.

This 18-year cluster-randomized controlled trial encompassing 15 villages included 1008 patients (454 men and 40 women in the intervention group [mean age, 54 ± 10 years]; 482 men and 32 women in the control group [mean age, 53 ± 10 years]) with confirmed COPD or at risk for COPD. Villages were randomly assigned to the intervention or the control group, and study participants residing within the villages received treatment accordingly. Intervention group patients took part in a program that included systematic health education, smoking cessation counseling, and education on management of COPD. Control group patients received usual care. The groups were compared after 18 years regarding the incidence of COPD, decline in lung function, and mortality of COPD. COPD incidence was lower in the intervention group than in the control group (10% vs 16%, <0.05). A decline in lung function was also significantly delayed in the intervention group compared to the control group of COPD and high-risk patients. The intervention group showed significant improvement in smoking cessation compared with the control group, and smokers in the intervention group had lower smoking indices than in the control group (350 vs 450, <0.05). The intervention group also had a significantly lower cumulative COPD-related death rate than the control group (37% vs 47%, <0.05). A rural community-based integrated intervention is effective in reducing the incidence of COPD among those at risk, delaying a decline in lung function in COPD patients and those at risk, and reducing mortality of COPD.

This preliminary study was designed to develop empirically a scale of compulsive sexual behavior (CSB) and to test its reliability and validity in a sample of individuals with nonparaphilic CSB (N = 15), in a sample of pedophiles (N = 35) in treatment for sexual offending, and in a sample of normal controls (N = 42). Following a factor analysis and a varimax rotation, those items with factor loadings on the rotated factors of greater than .60 were retained. Three factors were identified, which appeared to measure control, abuse, and violence. Cronbach's alphas indicated that the subscales have good reliability. The 28-item scale was then tested for validity by a linear discriminant function analysis. The scale successfully discriminated the nonparaphilic CSB sample and the pedophiles from controls. Further analysis indicated that this scale is a valid measure of CSB in that there were significant differences between the three groups on the control subscale. Pedophiles scored significantly lower than the other two groups on the abuse subscale, with the other two groups not scoring significantly differently from one another. This indicated that pedophiles were more abusive than the nonparaphilic CSB individuals or the controls. Pedophiles scored significantly lower than controls on the violence subscale. Nonparaphilic individuals with compulsive sexual behavior scored slightly lower on the violence subscale, although not significantly different. As a preliminary study, there are several limitations to this study, which should be addressed, in further studies with larger sample sizes.

Anterior encephaloceles are rare malformations that are frequently associated with other brain anomalies. This study evaluates the growth and psychological development of children following encephalocele repair. Growth and psychological assessment was done in 24 children with only encephalocele (group I); nine children with encephalocele and hydrocephalus (group II); seven children with encephalocele, hydrocephalus, and secondary malformations (group III); and 40 apparently healthy control subjects. Psychological assessment was done by evaluating intelligence and temperament. Single-stage repair was performed in 38 children, and two underwent multistage repair. Major postoperative complications were noted in three individuals. The follow-up period ranged from 12 to 168 months, and during this time the growth velocity declined significantly among group II and group III patients when compared with control subjects. After adjusting the body mass index for age, our data revealed that group III participants had a significantly (P = 0.02) lower body mass index than the control group. Group III also had poor indices for intelligence quotient (P ≤ 0.01) and temperament (P ≤ 0.01). Female patients had lower temperament indices when compared with unaffected females with regard to approach withdrawal (P ≤ 0.01), mood (P = 0.026), and intensity (P = 0.03). Overall, increased disease severity adversely affected the psychological indices. Individuals with anterior encephalocele without associated intracranial defects had excellent postoperative outcomes in terms of growth and psychological developments. Hydrocephalus and agenesis of corpus callosum had the least impact on psychological development. However, the presence of secondary brain defects led to developmental delays. Gender differences in temperament may suggest a need for distinct treatment regimens to assess psychosocial well-being for males and females. Copyright © 2017 Elsevier Inc. All rights reserved.

Gastric cancer is a common malignant tumor. Our previous study demonstrated inhibitory effects of 3-bromopyruvate (3-BrPA) on pleural mesothelioma. Moreover, we found that 3-BrPA could inhibit human gastric cancer cell line SGC-7901 proliferation in vitro, but whether similar effects might be exerted in vivo have remained unclear. To investigate the effect of 3-BrPA to human gastric cancer implant tumors in nude mice. Animals were randomly divided into 6 groups: 3-BrPA low, medium and high dose groups, PBS negative control group 1 (PH7.4), control group 2 (PH 6.8-7.8) and positive control group receiving 5-FU. The TUNEL method was used to detect apoptosis, and cell morphology and structural changes of tumor tissue were observed under transmission electron microscopy (TEM). 3-BrPA low, medium, high dose group, and 5-FU group, the tumor volume inhibition rates were 34.5%, 40.2%, 45.1%, 47.3%, tumor volume of experimental group compared with 2 PBS groups (p<0.05), with no significant difference between the high dose and 5-FU groups (p>0.05). TEM showed typical characteristics of apoptosis. TUNEL demonstrated apoptosis indices of 28.7%, 39.7%, 48.7% for the 3-BrPA low, medium, high dose groups, 42.2% for the 5-FU group and 5% and 4.3% for the PBS1 (PH7.4) and PBS2 (PH6.8-7.8) groups. Compared each experimental group with 2 negative control groups, there was significant difference (p<0.05); there was no significant difference between 5-FU group and medium dose group (p>0.05), but there was between the 5-FU and high dose groups (p<0.05). This study indicated that 3-BrPA in vivo has strong inhibitory effects on human gastric cancer implant tumors in nude mice .

In this study we evaluated the therapeutic utility of curcumin in a rodent model of acoustic trauma using histopathology, immunohistochemical, and distortion product otoacoustic emission (DPOAEs) measurements. 28 Wistar albino rats were included in the study and randomly assigned to 4 treatment groups. The first group (group 1) served as the control and was exposed to acoustic trauma alone. Group 2 was the curcumin group. Group 3 was the curcumin plus acoustic trauma group. Group 4 was the saline plus acoustic trauma group. Otoacoustic emission measurements were collected at the end of the experiment and all animals were sacrificed. Cochlea were collected and prepared for TUNEL (TdT-mediated deoxyuridinetriphosphate nick end-labelling) staining assay. Group 3 maintained baseline DPOAEs values at 3000 Hz, 4000 Hz and 8000 Hz on the 3rd and 5th day of the experiment. DPOAEs results were correlated with the immunohistochemical and histopathological findings in all groups. In comparison to the histopathologic control group, Group 1 exhibited a statistically significant increase in apoptotic indices in the organ of Corti, inner hair cell, and outer hair cell areas (p < 0.05). Relative to the control group, rats in Group 3 showed little increase in inner hair cell and outer hair cell apoptotic indices. Our results support the conclusion that curcumin may protect the cochlear tissues from acoustic trauma in rats. Curcumin injection prior to or after an acoustic trauma reduces cochlear hair cell damage and may protect against hearing loss. Copyright © 2017 Elsevier B.V. All rights reserved.

The therapeutic effect of Traditional Chinese Medicine (TCM) on chronic obstructive pulmonary disease (COPD) has been know for numerous years; however, the mechanism of action of the beneficial effects of TCM remains to be elucidated. The present study aimed to investigate the molecular mechanisms of COPD through metabolomic analysis as well as explore the targets and intervention mechanisms of TCM therapy using the common TCM granules Bu‑Fei Jian‑Pi. COPD rat models were established using smoke inhalations and recurrent bacterial infections. Rats were then divided into three groups as follows: A1, control healthy rats; B1, COPD model; and D1, Bu‑Fei Jian‑Pi‑treated COPD rats. Following administration of the medicine, the metabolomic profile of the lung tissue of rats in each group was assessed using high‑performance liquid chromatography/quadrupole‑time‑of‑flight mass spectrometry. The results demonstrated that there was a significanlty different spectrum of metabolites in the lung tissue of the model group compared to that of the control group as well as the Bu‑Fei Jian‑Pi‑treated COPD group; in addition, following treatment with Bu‑Fei Jian‑Pi, the metabolites of COPD rats were comparable with those of the control. Notable changes were observed in 31 metabolites between the Bu‑Fei Jian‑Pi‑treated group and the model group; however, there were 13 comparable metabolites between the Bu‑Fei Jian‑Pi and control groups as well as the model and control groups. Eleven metabolites showed a negative fold change in the Bu‑Fei Jian‑Pi‑treated groups compared to concentrations in the model group; however, minimal changes were observed in phenylpyruvic acid and α‑D‑fucose expression. In conclusion, the results of the present study demonstrated that Bu‑Fei Jian‑Pi granules had beneficial effects on measured outcomes in a rat model of stable COPD, indicated by a significantly different spectrum of metabolites. This therefore indicated that the metabolites which had significantly altered expression in the model group compared with that of the control and Bu‑Fei Jian‑Pi‑treated groups may be potential biomarkers of COPD.

The aim of this study was to analyze and compare the effects of tobacco on salivary pH between tobacco chewers, smokers and controls. A total of 60 subjects (males and females) aged 25-40 years, were divided equally into three groups: Tobacco smokers (Group A), chewers (Group B) and controls (Group C). Saliva of each subject was collected under resting condition. Salivary pH was determined using the specific salivary pH meter. The mean (±standard deviation) pH for Group A was 6.75 (±0.11), Group B was 6.5 (±0.29) and Group C was 7.00 (±0.28) after comparison. The significant results showed lower salivary pH in Groups A and B as compared to controls. Salivary pH was lowest in Group B compared to Group A and Group C. This study indicates that a lower (acidic) salivary pH was observed in tobacco users as compared with control. These alterations in pH due to the long-term effect of tobacco use can render oral mucosa vulnerable to various oral and dental diseases.

To investigate whether preoperative enteral diets -enriched in eicosapentaenoic acid (EPA) supplements could reduce the incidence of hypercytokinemia after pancreatoduodenectomy (PD) in a double-blinded randomized -controlled trial. Patients with resectable periampullary cancer were randomized into either the control group or the treatment group. Patients in the treatment group received oral supplementation (600 kcal/day) containing EPA for 7 days before surgery. Patients in the control group received isocaloric isonitrogenous standard nutrition (600 kcal/day) without EPA for 7 days before surgery. The primary endpoint was postoperative serum concentrations of interleukin-6 (IL-6). The secondary endpoints were the postoperative nutritional status and the incidence of postoperative infectious complications. Twenty-four patients were enrolled in the present study. After exclusion, 20 patients (control group, n = 9; treatment group, n = 11) were analyzed. There were no significant differences in the curves for the serum concentration of IL-6 (p = 0.68) or the incidence of infectious complications between the 2 groups (control group: 78%, treatment group: 55%, p = 0.37). The results of a double-blinded randomized controlled trial indicated that preoperative immunonutrition had no marked impact on the rates of postoperative hypercytokinemia or infectious complications after PD. © 2018 S.

To assess the efficacy of using magnetic resonance imaging measurements of retinal oxygenation response to detect early diabetic retinopathy in patients with Type 2 diabetes. Magnetic resonance imaging was conducted during 100% oxygen inhalation in patients with Type 2 diabetes with either no diabetic retinopathy (n = 12) or mild to moderate background diabetic retinopathy (n = 12), as well as in healthy control subjects (n = 12). Meanwhile, changes in retinal oxygenation response were measured. In the healthy control group, levels of retinal oxygenation response increased slowly during 100% oxygen inhalation. In contrast, they increased more quickly and attained homeostasis much earlier in the groups with background diabetic retinopathy (at the 20-min time point) and with no diabetic retinopathy (at the 25-min time point) than in the healthy control group (at the 42-min time point). Furthermore, levels of retinal oxygenation response in the group with background diabetic retinopathy increased more than that of the group with no diabetic retinopathy, which in turn increased more than that of the healthy control group. There are statistically significant differences between the group with background diabetic retinopathy and the healthy control group at 6-, 8-, 10-, 15-, 20- and 25-min time points (P < 0.05). According to the normal range of the healthy control group by setting fundus photography results as 'gold standard' in our research, the sensitivity, specificity, positive predictive value, negative predictive value and receiver operating characteristic area for reporting the early indications of utility of diabetic retinopathy were 83.33%, 58.33%, 50%, 87.5% and 0.774, respectively. The results indicate that magnetic resonance imaging is a potential screening method and probably a quantitative physiological biomarker to find early diabetic retinopathy in patients with Type 2 diabetes. © 2011 The Authors.

Purpose Current in-hospital management of exacerbations of COPD is suboptimal, and patient outcomes are poor. The primary aim of this study was to evaluate whether implementation of a care pathway (CP) for COPD improves the 6 months readmission rate. Secondary outcomes were the 30 days readmission rate, mortality, length of stay and adherence to guidelines. Patients and methods An international cluster randomized controlled trial was performed in Belgium, Italy and Portugal. General hospitals were randomly assigned to an intervention group where a CP was implemented or a control group where usual care was provided. The targeted population included patients with COPD exacerbation. Results Twenty-two hospitals were included, whereof 11 hospitals (n=174 patients) were randomized to the intervention group and 11 hospitals (n=168 patients) to the control group. The CP had no impact on the 6 months readmission rate. However, the 30 days readmission rate was significantly lower in the intervention group (9.7%; 15/155) compared to the control group (15.3%; 22/144) (odds ratio =0.427; 95% confidence interval 0.222–0.822; P=0.040). Performance on process indicators was significantly higher in the intervention group for 2 of 24 main indicators (8.3%). Conclusion The implementation of this in-hospital CP for COPD exacerbation has no impact on the 6 months readmission rate, but it significantly reduces the 30 days readmission rate. PMID:27920516

When the going gets tough...: Self-motivation is associated with invigoration and fun.

Personality systems interaction (PSI) theory postulates two executive control modes in volitional action: Self-control and self-regulation (self-motivation). Self-control should deplete energy whereas self-motivation should maintain energy and result in invigoration. There were three groups of participants: Self-control, self-motivation, and pretend, who performed a resource-demanding Stroop-Shift and an anagram task. Performance and energy expenditure were examined in each task. Compared to the other groups, the self-motivation group showed increments in blood glucose throughout the experiment, indicating invigoration, and had better performance on the difficult Stroop-Shift task than the self-control group. Additionally, for the self-motivation group anagram performance correlated with less effort and ease of concentration and was moderated by fun in the task. These results are consonant with the predictions of PSI and self-determination theories. It is concluded that self-control depletes resources whereas self-motivation is associated with invigoration in carrying resource-demanding tasks.

A growing body of research has reported a bilingual advantage in performance on executive control tasks, but it is not known at what point in emerging bilingualism these advantages first appear. The present study investigated the effect of early stage second-language training on executive control. Monolingual English-speaking students were tested on a go-nogo task, sentence judgment task, and verbal fluency, before and after 6 months of Spanish instruction. The training group (n = 25) consisted of students enrolled in introductory Spanish and the control group (n = 30) consisted of students enrolled in introductory Psychology. After training, the Spanish group showed larger P3 amplitude on the go-nogo task and smaller P600 amplitude on the judgment task, indicating enhanced performance, with no changes for the control group and no differences between groups on behavioral measures. Results are discussed in terms of neural changes underlying executive control after brief second-language learning. Copyright © 2014 Elsevier Inc. All rights reserved.

We analyzed the levels of selected micro-RNAs in normal prostate tissue to assess their potential to indicate tumor foci elsewhere in the prostate. Histologically normal prostate tissue samples from 31 prostate cancer patients and two cancer negative control groups with either unsuspicious or elevated prostate specific antigen (PSA) levels (14 and 17 individuals, respectively) were analyzed. Based on the expression analysis of 157 microRNAs in a pool of prostate tissue samples and information from data bases/literature, we selected eight microRNAs for quantification by real-time polymerase chain reactions (RT-PCRs). Selected miRNAs were analyzed in histologically tumor-free biopsy samples from patients and healthy controls. We identified seven microRNAs (miR-124a, miR-146a & b, miR-185, miR-16 and let-7a & b), which displayed significant differential expression in normal prostate tissue from men with prostate cancer compared to both cancer negative control groups. Four microRNAs (miR-185, miR-16 and let-7a and let-7b) remained to significantly discriminate normal tissues from prostate cancer patients from those of the cancer negative control group with elevated PSA levels. The transcript levels of these microRNAs were highly indicative for the presence of cancer in the prostates, independently of the PSA level. Our results suggest a microRNA-pattern in histologically normal prostate tissue, indicating prostate cancer elsewhere in the organ. PMID:23459235

This project studied the lowering blood lipids effect in atherosclerotic ApoE-deficient mice. Group A mice (n = 6), fed with a normal diet, served as the negative control. The experimental groups used mice fed with a high cholesterol diet (HCD) for eight weeks, and then selected for inclusion in the study on the basis of high blood lipid levels and the formation of atherosclerotic lesion plaque, which was indicated by an ultrasound biomicroscopy test. Eighteen mice met the selection criteria (atherosclerotic mice with high blood lipid levels) and these were randomly assigned into three groups B, C and D (n = 6). Group B fed with a HCD, served as the positive control. The intervention Group C was fed with HCD and Simvastatin. The intervention Group D was fed with a HCD and Hawthorn fruit compound (HFC includes Hawthorn and Kiwi fruit extract) for eight weeks. The results showed that after feeding on a HCD, Group B had significantly higher blood lipid levels compared to Group A and this confirmed the validity of Group A and Group B controls in this study. The results also showed that compared to Group B, in both Group C and D, there was a significant reduction in triglyceride and in the ratio between low-density lipoprotein cholesterol (LDL-C) and serum cholesterol. Moreover a reduction of LDL-C was evident in Group D, whereas a similar effect did not occur in Group C. The results indicate that HFC can be considered for the treatment of hyperlipidemia and prevention of atherosclerosis.

Depression is a disabling condition affecting people of all ages, but generally starting during adolescence. Schools seem to be an excellent setting where preventive interventions may be delivered. This study aimed to test the effectiveness of an indicated school-based intervention to reduce depressive symptoms among at-risk adolescents from low-income families. A two-arm, parallel, randomized controlled trial was conducted in 11 secondary schools in vulnerable socioeconomic areas in Santiago, Chile. High-risk students in year 10 (2° Medio) were invited to a baseline assessment (n = 1048). Those who scored ≥10 (boys) and ≥15 (girls) in the BDI-II were invited to the trial (n = 376). A total of 342 students consented and were randomly allocated into an intervention or a control arm in a ratio of 2:1. The intervention consisted of 8 group sessions of 45 min each, based on cognitive-behavioural models and delivered by two trained psychologists in the schools. Primary (BDI-II) and secondary outcomes (measures of anxiety, automatic thoughts and problem-solving skills) were administered before and at 3 months post intervention. The primary outcome was the recovery rate, defined as the proportion of participants who scored in the BDI-II <10 (among boys) and <15 (among girls) at 3 months after completing the intervention. There were 229 participants in the intervention group and 113 in the control group. At 3-month follow-up 81.4 % in the intervention and 81.7 % in the control group provided outcome data. The recovery rate was 10 % higher in the intervention (50.3 %) than in the control (40.2 %) group; with an adjusted OR = 1.62 (95 % CI: 0.95 to 2.77) (p = 0.08). No difference between groups was found in any of the secondary outcomes. Secondary analyses revealed an interaction between group and baseline BDI-II score. We found no clear evidence of the effectiveness of a brief, indicated school-based intervention based on cognitive-behavioural models on reducing depressive symptoms among Chilean adolescents from low-income families. More research is needed in order to find better solutions to prevent depression among adolescents. Current Controlled Trials ISRCTN33871591 . Retrospectively registered 29 June 2011.

The Attention Network Test (ANT) was used to examine alerting, orienting, and executive control in fetal alcohol spectrum disorder (FASD) versus attention deficit hyperactivity disorder (ADHD). Participants were 113 children aged 7 to 10 years (31 ADHD-Combined, 16 ADHD-Primarily Inattentive, 28 FASD, 38 controls). Incongruent flanker trials triggered slower responses in both the ADHD-Combined and the FASD groups. Abnormal conflict scores in these same two groups provided additional evidence for the presence of executive function deficits. The ADHD-Primarily Inattentive group was indistinguishable from the controls on all three ANT indices, which highlights the possibility that this group constitutes a pathologically distinct entity.

The effects of low intensity noise on cognitive learning and autonomous physiological processes are of high practical relevance but are rarely addressed in empirical investigations. This study investigated the impact of neighbourhood noise (of 45 dB[A], n=20) and of noise coming from passing aircraft (of 48 dB[A] peak amplitude presented once per minute; n=19) during computer based learning of different texts (with three types of text structure, i.e. linear text, hierarchic hypertext, and network hypertext) in relation to a control group (35 dB[A], n=20). Using a between subjects design, reproduction scores, heart rate, and spontaneous skin conductance fluctuations were compared. Results showed impairments of reproduction in both noise conditions. Additionally, whereas in the control group and the neighbourhood noise group scores were better for network hypertext structure than for hierarchic hypertext, no effect of text structure on reproduction appeared in the aircraft noise group. Compared to the control group, for most of the learning period the number of spontaneous skin conductance fluctuations was higher for the aircraft noise group. For the neighbourhood noise group, fluctuations were higher during pre- and post task periods when noise stimulation was still present. Additionally, during the last 5 min of the 15 min learning period, an increased heart rate was found in the aircraft noise group. Data indicate remarkable cognitive and physiological effects of low intensity background noise. Some aspects of reproduction were impaired in the two noise groups. Cognitive learning, as indicated by reproduction scores, was changed structurally in the aircraft noise group and was accompanied by higher sympathetic activity. An additional cardiovascular load appeared for aircraft noise when combined with time pressure as indicated by heart rate for the announced last 5 min of the learning period during aircraft noise with a peak SPL of even 48 dB(A). Attentional mechanisms (attentional control) like being threatened by passing aircraft approaching the airport, higher demands of selective filtering, and difficulties in changing cognitive strategies during noise are discussed as underlying mechanisms.

Nusinersen is an antisense oligonucleotide drug that modulates pre-messenger RNA splicing of the survival motor neuron 2 ( SMN2) gene. It has been developed for the treatment of spinal muscular atrophy (SMA). We conducted a multicenter, double-blind, sham-controlled, phase 3 trial of nusinersen in 126 children with SMA who had symptom onset after 6 months of age. The children were randomly assigned, in a 2:1 ratio, to undergo intrathecal administration of nusinersen at a dose of 12 mg (nusinersen group) or a sham procedure (control group) on days 1, 29, 85, and 274. The primary end point was the least-squares mean change from baseline in the Hammersmith Functional Motor Scale-Expanded (HFMSE) score at 15 months of treatment; HFMSE scores range from 0 to 66, with higher scores indicating better motor function. Secondary end points included the percentage of children with a clinically meaningful increase from baseline in the HFMSE score (≥3 points), an outcome that indicates improvement in at least two motor skills. In the prespecified interim analysis, there was a least-squares mean increase from baseline to month 15 in the HFMSE score in the nusinersen group (by 4.0 points) and a least-squares mean decrease in the control group (by -1.9 points), with a significant between-group difference favoring nusinersen (least-squares mean difference in change, 5.9 points; 95% confidence interval, 3.7 to 8.1; P<0.001). This result prompted early termination of the trial. Results of the final analysis were consistent with results of the interim analysis. In the final analysis, 57% of the children in the nusinersen group as compared with 26% in the control group had an increase from baseline to month 15 in the HFMSE score of at least 3 points (P<0.001), and the overall incidence of adverse events was similar in the nusinersen group and the control group (93% and 100%, respectively). Among children with later-onset SMA, those who received nusinersen had significant and clinically meaningful improvement in motor function as compared with those in the control group.

The aim of this study was to investigate the effects on fitness indicators and subjective health-perception of a multimodal exercise program provided by a district in Budapest among community-living seniors. Sixty community-living older adults aged over 60 years formed beginner group (who were at the beginning of the exercise program), advanced group (who had been in the programme for 3-6 months), active group (who had been participating in the exercise program for at least 6 months, in addition to Nordic walking program) and a physically inactive control group. Balance, functional mobility, lower and upper limb strength, lower and upper body flexibility, aerobic endurance and self-reported health perception were measured at baseline, and after a 12-week follow-up period. The beginner group and the advanced group improved in upper body flexibility (beginner Δ=1.2; d=0.83; advanced: Δ=1.7; d=1.39), lower body flexibility (beginner: Δ=1.7, d=0.484; advanced: Δ=1.9; d=1.55), lower limb strength (beginner: Δ=1.47; d=0.84; advanced: Δ=1.57; d=0.72), and functional mobility (beginner: Δ=-0.6; d=0.54; advanced: Δ=-0.4; d=0.90). There were also improvements in aerobic endurance (Δ=11.06; d=0.96) and balance (Δ=1.6; d=0.62) of beginner group. These indicators declined in the control group. Indicators of the active group did not change. The self-perceived health status declined (Δ=-13.9; d=0.73) in the control group but did not change in any exercising groups. This multimodal exercise program can be effective among community-living older adults, even in Hungary, a country where geriatric physical activity is not widespread. Therefore, it would be useful to extend this model program to other settlements as well.

To study human teratogenic potential of furazidine treatment during pregnancy. Pair analysis of cases with congenital abnormalities and matched population controls. The Hungarian Case-Control Surveillance of Congenital Abnormalities. 38,151 pregnant women who had newborn infants without any defects (population control group) and 22,865 pregnant women who had newborns or fetuses with congenital abnormalities between 1980 and 1996. In the case group, 157 (0.7%) and in the control group, 254 (0.7%) pregnant women were treated with furazidine. The case-control pair analysis did not indicate a teratogenic potential of furazidine use during the second to third months of gestation, i.e. in the critical period for major congenital abnormalities. Treatment with furazidine during pregnancy did not show teratogenic risk to the fetus.

Cutaneous leishmaniasis is a health problem in the world. Lesions should be treated on cosmetically or functionally important sites, such as the face and hands. Cantharidin is a terpenoid compound produced naturally by beetles of Meloidae and Oedemeridae families. The current study aimed to investigate the effect of cantharidin on Cutaneous Leishmaniasis (CL) lesions and IFN-γ and IL-4 patterns in infected BALB/c mice. INFECTED BALB/C MICE WERE DIVIDED INTO FIVE GROUPS AS: untreated (control group), eucerin-treated and 0.05%, 0.1% and 0.5% cantharidin-treated. Lesions diameter was measured by Vernier caliper every three days for four weeks. Cytokines levels were measured by enzyme-linked immunosorbent assay (ELISA) using U-CyTech kit. The results indicated that treatment with cantharidin exacerbates lesions compared with the controls, except for 0.05% cantharidin dose that restrained lesion growth significantly. Interferon gamma level in cantharidin-treated groups was significantly less than that of the control group. But interlukin-4 level was similar among the groups. The current study results indicated that high doses of cantharidin exacerbates leishmaniasis lesion, but low dose of cantharidin inhibits lesion growth.

Impaired empathy is regarded as a psychological consequence of childhood maltreatment, yet few studies have explored this relationship empirically. We investigated whether empathy differed in healthy and maltreated individuals by examining their emotional responses to people in distress. Forty-nine individuals (age 20 to 60) viewed short film clips from the South African Truth and Reconciliation Commission testimonies depicting dialogues between victims and perpetrators of gross human rights violations. Participants were divided into 3 groups based on their scores on the Childhood Trauma Questionnaire: control (n = 18), moderate maltreatment (n = 21), and severe maltreatment (n = 10). We employed a mixed-methods design to explore empathic responses to film clips both quantitatively and qualitatively. Quantitative results indicated that self-reported empathy was lower in the moderate maltreatment group compared to the control group, but of similar strengths in the severe maltreatment and control groups. However, qualitative thematic analysis indicated that both maltreatment groups displayed themes of impaired empathy. Our results support the notion that childhood maltreatment is associated with impaired empathy, and suggest that such impairment may differ depending on the level of maltreatment: moderate maltreatment was associated with emotional blunting and impaired cognitive empathy, whereas severe maltreatment was associated with emotional over-arousal and diminished cognitive insight.

We studied the effect of alcohol on the pineal gland of 48 male Wistar rats. Animals were divided into control and experimental groups. The experimental group underwent a previous progressive alcoholisation period with ethanol diluted in water at a concentration of 40%. Animals were sacrificed at 3, 6, 9 and 12 months, and the ultrastructure, karyometric indices, and number of synaptic bodies in the pineal gland were analysed. The results showed progressive morphologic alterations in the ethanol-treated animals, which culminated in fatty degeneration of the pineal parenchyma after 6 months. The karyometric indices decreased in both the central and peripheral areas compared with the control group. Moreover, the seasonal rhythmicity observed in the controls disappeared in the experimental groups, whose number of different populations of synaptic bodies (synaptic ribbons and synaptic spherules) considerably lowered with inversion of their normal seasonal rhythm. These results support that chronic alcoholisation leads to fatty degeneration of the pineal parenchyma, and a considerable alteration in nuclear functional rhythms and synaptic bodies.

1 Seven randomized controlled trials of intravenous nitroglycerin in a total of about 850 patients have been reported. Overall, there were 51 deaths (12.5%) in the nitroglycerin group and 87 (20%) in the control group. This indicates a 48% reduction in the odds of death (P < 0.001, 95% confidence limits (25% to 64%)). 2 There are five randomized trials of oral nitrates after acute myocardial infarction. In these trials, 11.8% of the patients in the nitrate group compared with 13.3% in the control group died. This indicates a nonsignificant 12% reduction in the odds of death but the 95% confidence interval overlaps widely with the i.v. trials. If all trials of i.v. or oral nitrates are considered the reduction in the odds of death is 32% (P < 0.01). 3 Nitrates have a beneficial effect on haemodynamics in heart failure but the data on mortality effects are sparse. In combination with hydralazine, however, long-term mortality was reduced in the V-HEFT trial of chronic heart failure. PMID:1633075

This study aimed to examine the effect of group-based psychodrama therapy on the level aggression in adolescents. The study included 23 students from Nezihe Yalvac Anatolian Vocational High School of Hotel Management and Tourism that had high aggression scores. Eleven of the participants (6 female, 5 male) constituted the experimental group and 12 (6 male, 6 female) were in the control group. The 34-item Aggression Scale was used to measure level of aggression. We utilized mixed pattern design including experiment-control, pre-test and post test and follow up. The experimental group participated in group-based psychodrama therapy once a week for 90 minutes, for 14 weeks in total. The Aggression Scale was administered to the experimental and control groups before and after treatment; it was additionally administered to the experimental group 16 weeks after treatment. Data were analyzed using ANCOVA and dependent samples t tests. Our analysis shows that group-based psychodrama had an effect on the experimental group in terms of total aggression, anger, hostility, and indirect aggression scores (F=65.109, F=20.175, F=18.593, F=40.987, respectively, P<.001). There was no effect of the group-based treatment on verbal or physical aggression scores. Follow-up indicated that the effect of the therapy was still measureable 16 weeks after the cessation of the therapy. Results of the present study indicate that group-based psychodrama therapy decreased the level of aggression in the experimental group. Current findings are discussed with reference to the literature. Recommendations for further research and for psychiatric counselors are provided.

The beneficial role of exercise in maintaining health in patients with cystic fibrosis (CF) is well described. Few data exist on the effect of exercise on respiratory muscle function in patients with CF. Our objective was to compare respiratory muscle function indices in CF patients that regularly exercise with those CF patients that do not. This cross-sectional study assessed nutrition, pulmonary function and respiratory muscle function in 37 CF patients that undertook regular aerobic exercise and in a control group matched for age and gender which consisted of 44 CF patients that did not undertake regular exercise. Respiratory muscle function in CF was assessed by maximal inspiratory pressure (Pimax), maximal expiratory pressure (Pemax) and pressure-time index of the respiratory muscles (PTImus). Median Pimax and Pemax were significantly higher in the exercise group compared to the control group (92 vs. 63 cm H2O and 94 vs. 64 cm H2O respectively). PTImus was significantly lower in the exercise group compared to the control group (0.089 vs. 0.121). Upper arm muscle area (UAMA) and mid-arm muscle circumference were significantly increased in the exercise group compared to the control group (2608 vs. 2178 mm2 and 23 vs. 21 cm respectively). UAMA was significantly related to Pimax in the exercising group. These results suggest that CF patients that undertake regular aerobic exercise maintain higher indices of respiratory muscle strength and lower PTImus values, while increased UAMA values in exercising patients highlight the importance of muscular competence in respiratory muscle function in this population.

To explore whether edaravone protects cells damage via mitogen-activated protein kinases (MAPKs) signal pathway, and which procedure of p38 be affected so as to add theories for AD pathogenesis and treatments. According to different drugs treated, PC12 cells in vitro were divided into four groups. Negative control group: cells were treated with media alone. AD model group: cells were treated with 30 pmol/L Abeta(25-35). Inhibitor control group: cells were treated with 10 micromol/L SB203580 Cp38 mitogen-activated protein kinase (p38) inhibitor], 10 micromol/L SP600125 [c-Jun NH2 terminal kinase (JNK) inhibitor], or 10 micromol/L PD98059 extracelular signal regulated kinase (ERK) inhibitor]. Low-dose, middle-dose and high-dose edaravone group: cells plated for 24 hours treated with 30 micromol/L Abeta(25-35) and co-treated with 20, 40, 80 micromol/L edaravone 3 hours, respectively. The morphology of the treated cells were observed, the p-p38, p-JNK and p-ERK proteins in each group were tested by the Western blot. The p38 mRNA were tested in each group above (only add SB203580 10 micromol/L in third group) by the real time PCR. (1) The p-p38 protein was significantly increased in model control group compared with that in negative control group (P<0.05). The p-p38 protein in the inhibitor group and edaravone groups was decreased significantly (P<0.05) when compared with that in model control group. The p-p38 proteins were significantly increased in the three edaravone groups compared with that in inhibiter control group (P<0.05). The p-p38 protein in middle-dose edaravone group was decreased compared with that in low-dose edaravone group (P<0.05). There was no relationship in dose-dependent manner about edaravone. Compared with three edaravone groups, the p-p38 protein was lower than it in high-dose edaravone & inhibiter group (P<0.05). (2) The p-JNK protein was significantly increased in model control group compared with that in negative control group (P<0.05). The p-JNK protein in the inhibitor group was decreased compared with that in model control group (P<0.05). (3) No significantly difference of p-ERK protein concentration was observed in other groups when compared with that in negative control group (P>0.05 each). (4) Compared with negative control group, the p38 mRNA in model control group was significantly increased, and it was significantly decreased in inhibitor control group (P<0.05 each). In 40 micromol/L and 80 micromol/L edaravone groups, the p38 mRNA was significantly decreased compared with that in model control group, and it still was decreased compared with that in inhibitor control group (P<0.05). The p38 mRNA in 40 micromol/L edaravone group was the lowest among three edaravone groups, and it was obviously different from that in 20 micromol/L and 80 micromol/L edaravone groups (P<0.05). Abeta(25-35) could increase the p-p38 and p-JNK protein expression in cultured PC12 cells, but there was no obviously expression of p-ERK protein. These indicated that Abeta(25-35) might activate MAPKs signal pathway, especially p38 and JNK, and lead to PC12 cell damage. Edaravone could decrease p38 mRNA induced-Abeta(25-35), which indicated edaravone could protect PC12 cell damage via blocking p38 signal pathway in mRNA stage and protein stage simultaneously. Hence, it is promising that edaravone would be a new medicine for AD.

ABSTRACT Background Injury has been linked with altered postural control in active populations. The association between running injury and dynamic postural control has not been examined. Hypothesis/Purpose The purpose of this study was to examine dynamic postural control in injured and uninjured runners using the Star Excursion Balance Test (SEBT), Time to Stabilization (TTS) of ground reaction forces following a single-leg landing, and postural stability indices reflecting the fluctuations in GRFs during single-leg landing and stabilization tasks (forward and lateral hop). It was hypothesized that dynamic postural control differences would exist between runners with a history of injury that interrupted training for ≥7 days (INJ) when compared to runners without injury (CON). Design Case-control study Methods Twenty-two INJ (14 F, 8 M; 23.7 ± 2.1 y; 22.3 ± 2.8 kg/m2; 29.5 ± 16.3 mi/wk) currently running > 50% pre-injury mileage without pain were compared with twenty-two matched CON (14F, 8M; 22.7 ± 1.2 y; 22.7 ± 2.7 kg/m2; 31.2 ± 19.6 mi/wk). INJ group was stratified by site of injury into two groups (Hip/Thigh/Knee and Lower Leg/Ankle/Foot) for secondary analysis. Leg length-normalized anterior, posterolateral, and posteromedial reach distances on the SEBT, medial/lateral and anterior/posterior ground reaction force TTS, directional postural stability indices, and a composite dynamic postural stability index (DPSI), were assessed using mixed model ANOVA (α=0.05) and effect sizes (d). Results No group X direction interaction or group differences were observed for the SEBT (p=0.51, 0.71) or TTS (p=0.83, 0.72) measures. A group X direction interaction was found for postural stability indices during the forward landing task (p<0.01). Both Hip/Thigh/Knee and Lower leg/Ankle/Foot INJ groups demonstrated a greater vertical postural stability index (VPSI) (p=0.01 for both, d=0.80, 0.95) and DPSI (p=0.01, 0.02, d=0.75, 0.93) when compared to CON suggesting impaired balance control. A group X direction interaction was also found for postural stability indices during the lateral landing task (p=0.03). Only the Hip/Thigh/Knee INJ runners displayed a greater VPSI (p=0.01, d=0.91) and DPSI (p=0.017, d=0.89) when compared to CON. Conclusions When compared to CON, INJ runners demonstrated impaired dynamic control of vertical forces when performing the single leg landing and stabilization tasks. Clinicians should consider addressing dynamic control of vertical loads through functional tasks during the rehabilitation of running injury. Level of Evidence Level 3 PMID:27274423

Converging evidence suggests that developmental dyslexia is a neurobiological disorder, characterized by deficits in the auditory, visual, and linguistic domains. In the longitudinal project of the Dutch Dyslexia Programme, 180 children with a familial risk of dyslexia (FR) and a comparison group of 120 children without FR (noFR) were followed from the age of 2 months up to 9 years. Children were assessed on (1) auditory, speech, and visual event-related potentials every half year between 2 and 41 months; (2) expressive and receptive language, motor development, behaviour problems, and home-literacy environment by questionnaires at the age of 2 and 3; (3) speech-language and cognitive development from 47 months onwards; and (4) preliteracy and subskills of reading, and reading development during kindergarten and Grades 2 and 3. With regard to precursors of reading disability, first analyses showed specific differences between FR and noFR children in neurophysiological, cognitive, and early language measures. Once reading tests administered from age 7 to 9 years were available, the children were divided into three groups: FR children with and without dyslexia, and controls. Analyses of the differences between reading groups yielded distinct profiles and developmental trajectories. On early speech and visual processing, and several cognitive measures, performance of the non-dyslexic FR group differed from the dyslexic FR group and controls, indicating continuity of the influence of familial risk. Parental reading and rapid naming skills appeared to indicate their offspring's degree of familial risk. Furthermore, on rapid naming and nonverbal IQ, the non-dyslexic FR group performed similarly to the controls, suggesting protective factors. There are indications of differences between the FR and control groups, irrespective of reading outcome. These results contribute to the distinction between the deficits correlated to dyslexia as a manifest reading disorder and deficits correlated to familial risk only.

Objective: The incidence of gastrointestinal symptoms in diabetes is higher than that of non-diabetes. Thus, the aim of the present study was to observe the efficacy and safety of bifidobacterium tetragenous viable bacteria tablets in the treatment of constipation in patients with type 2 diabetes mellitus. Methods: This is a multicenter, randomized, double-blind, placebo-controlled, parallel group-comparison clinical research. The subjects were randomly divided into study group and control group according to 1∶1 ratio by computer generated random number method. The subjects were either treated with bifidobacterium tetragenous viable bacteria tablets (study group) or placebo (control group) for eight weeks, and they were followed up for four weeks without changing foundation therapy for diabetes. The primary outcome was the change of complete spontaneous bowel movements (CSBMs). Results: A total of 234 subjects (the study group:116 cases; the control group: 118 cases) from 7 centers were included in the present study. The baseline characteristics were comparable between the two groups. In the study group, the CSBMs at 0, 2, 4, 8 and 12 weeks were 0.0 (0.0, 1.0) , 1.0 (0.5, 2.0) , 2.0 (1.0, 3.0) , 3.0 (2.0, 3.5) , 2.0 (1.0, 3.0) times per week, respectively, while the CSBMs of the control group at each corresponding weeks were 0.0 (0.0, 1.0) , 1.0 (0.0, 1.5) , 1.0 (0.0, 1.5) , 1.0 (0.0, 2.0) , 1.0 (0.0, 1.5) times per week, respectively. There is significant difference in CSBMs between the two groups ( P< 0.05). Moreover, after 12 weeks treatment, the CSBMs over spontaneous bowel movements (SBMs) ratio in the study group was higher than that in the control group [0.53 (0.40, 0.67) vs 0.33 (0.00,0.50), P= 0.048], indicating a more complete evacuation sensation in the study group. More subjects in the study group (66.38%) reached Bristol stool classification of normal criteria than those in the control group (48.31%, P= 0.005). There were significantly improvement of bowel function index in the study group [study group 42.7 (33.3, 56.7), control group 60.6 (51.7, 75.7), P< 0.000 1]. Furthermore, the symptoms of constipation was improved, and the satisfaction for the treatment was high in the study group. There were no significant differences of the safety indicators between the two groups. Conclusions: Bifidobacterium tetragenous viable bacteria tablets can be used in patients with type 2 diabetes mellitus and constipation. Compared with placebo, it improves constipation and has no obvious adverse effects.

This study analysed the effects of upright weight bearing and the knee flexion angle on patellofemoral indices, determined using magnetic resonance imaging (MRI), in patients with patellofemoral instability (PI). Healthy volunteers (control group, n = 9) and PI patients (PI group, n = 16) were scanned in an open-configuration MRI scanner during upright weight bearing and supine non-weight bearing positions at full extension (0° flexion) and at 15°, 30°, and 45° flexion. Patellofemoral indices included the Insall-Salvati Index, Caton-Deschamp Index, and Patellotrochlear Index (PTI) to determine patellar height and the patellar tilt angle (PTA), bisect offset (BO), and the tibial tubercle-trochlear groove (TT-TG) distance to assess patellar rotation and translation with respect to the femur and alignment of the extensor mechanism. A significant interaction effect of weight bearing by flexion angle was observed for the PTI, PTA, and BO for subjects with PI. At full extension, post hoc pairwise comparisons revealed a significant effect of weight bearing on the indices, with increased patellar height and increased PTA and BO in the PI group. Except for the BO, no such changes were seen in the control group. Independent of weight bearing, flexing the knee caused the PTA, BO, and TT-TG distance to be significantly reduced. Upright weight bearing and the knee flexion angle affected patellofemoral MRI indices in PI patients, with significantly increased values at full extension. The observations of this study provide a caution to be considered by professionals when treating PI patients. These patients should be evaluated clinically and radiographically at full extension and various flexion angles in context with quadriceps engagement. Explorative case-control study, Level III.

Few studies have evaluated the biomarker changes of fluoride exposure. In order to explore early and sensitive indicators, animal experiment was designed. Ninety-six healthy SD rats (48 males and 48 females) weighing approximately 60 g were randomly divided into six groups of 16 animals each by gender average. Control animals were supplied with distilled water only as group 1. Exposure groups' animals were treated with 2, 4, 8, 16, and 32 mg NaF/kg bw, respectively, as groups 2, 3, 4, 5, and 6. Our study found that contents of white blood cell (WBC), lymphocyte percentage (LYMPH%), lymphocyte (LYM), mean platelet volume (MPV), and platelet distribution width (PDW) increased significantly in high-fluoride-exposure groups (p < 0.05), which revealed that immune system may be interfered by high fluoride. Meanwhile, levels of alanine aminotransaminase (ALT), aspartate aminotransaminase (AST), and ALT/AST in groups 5 and 6 decreased significantly compared to those in control group (p < 0.05), as well as the concentration of uric acid (UA) in groups 3, 4, 5, and 6 exhibited the same trends (p < 0.05). On the contrary, the level of blood B2 microglobulin (BB2MG) increased significantly (p < 0.05) in groups 4, 5, and 6. Changes of ALT, AST, UA, and BB2MG suggested the functions of the liver and kidney be altered by fluoride exposure. At the same time, the ATF4 content decreased gradually with the increase of fluoride concentration; furthermore, a highly significant (r = -0.586, p < 0.01) negative relationship between ATF4 content and fluoride exposure level was found. Results meant that clinical indicators cannot act as indicators of high fluoride exposure, and it also suggested that protein ATF4 might be the early and sensitive indicator in epidemiologic study of high fluoride exposure.

Objective To assess whether a warning system based on mobile SMS messages increases the adherence of HIV-infected Brazilian women to antiretroviral drug-based treatment regimens and their impressions and satisfaction with respect to incoming messages. Design A randomized controlled trial was conducted from May 2009 to April 2010 with HIV-infected Brazilian women. All participants (n = 21) had a monthly multidisciplinary attendance; each participant was followed over a 4-month period, when adherence measures were obtained. Participants in the intervention group (n = 8) received SMS messages 30 min before their last scheduled time for a dose of medicine during the day. The messages were sent every Saturday and Sunday and on alternate days during the working week. Participants in the control group (n = 13) did not receive messages. Measurements Self-reported adherence, pill counting, microelectronic monitors (MEMS) and an interview about the impressions and satisfaction with respect to incoming messages. Results The HIV Alert System (HIVAS) was developed over 7 months during 2008 and 2009. After the study period, self-reported adherence indicated that 11 participants (84.62%) remained compliant in the control group (adherence exceeding 95%), whereas all 8 participants in the intervention group (100.00%) remained compliant. In contrast, the counting pills method indicated that the number of compliant participants was 5 (38.46%) for the control group and 4 (50.00%) for the intervention group. Microelectronic monitoring indicated that 6 participants in the control group (46.15%) were adherent during the entire 4-month period compared to 6 participants in the intervention group (75.00%). According to the feedback of the 8 participants who completed the research in the intervention group, along with the feedback of 3 patients who received SMS for less than 4 months, that is, did not complete the study, 9 (81.81%) believed that the SMS messages aided them in treatment adherence, and 10 (90.90%) responded that they would like to continue receiving SMS messages. SMS messaging can help Brazilian women living with HIV/AIDS to adhere to antiretroviral therapy for a period of at least 4 months. In general, the results are encouraging because the SMS messages stimulated more participants in the intervention group to be adherent to their treatment, and the patients were satisfied with the messages received, which were seen as reminders, incentives and signs of affection by the health clinic for a marginalized population.

It has been proposed that playing chess enables children to improve their ability in mathematics. These claims have been recently evaluated in a meta-analysis (Sala & Gobet, 2016, Educational Research Review, 18, 46-57), which indicated a significant effect in favor of the groups playing chess. However, the meta-analysis also showed that most of the reviewed studies used a poor experimental design (in particular, they lacked an active control group). We ran two experiments that used a three-group design including both an active and a passive control group, with a focus on mathematical ability. In the first experiment (N = 233), a group of third and fourth graders was taught chess for 25 hours and tested on mathematical problem-solving tasks. Participants also filled in a questionnaire assessing their meta-cognitive ability for mathematics problems. The group playing chess was compared to an active control group (playing checkers) and a passive control group. The three groups showed no statistically significant difference in mathematical problem-solving or metacognitive abilities in the posttest. The second experiment (N = 52) broadly used the same design, but the Oriental game of Go replaced checkers in the active control group. While the chess-treated group and the passive control group slightly outperformed the active control group with mathematical problem solving, the differences were not statistically significant. No differences were found with respect to metacognitive ability. These results suggest that the effects (if any) of chess instruction, when rigorously tested, are modest and that such interventions should not replace the traditional curriculum in mathematics.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for inflammation control and pain relief. However, while the adjunct use of NSAIDs is avoided for periodontal therapy because of related side effects, cyclic administration of NSAIDs may reduce or eliminate these effects. We evaluated the effect of a cyclic diclofenac potassium (DP) regimen on clinical parameters and levels of prostaglandin E 2 (PGE 2 ) and interleukin-1β (IL-1β) in the gingival crevicular fluid (GCF) of individuals with periodontitis. The study protocol was approved by the Ethics Committee (2000/071). Forty-one individuals with chronic periodontitis (33 men, 8 women) were divided into two groups (test and control) after initial periodontal therapy. During this 6-month, randomized, double-blind, placebo-controlled study, test (n = 28) and control (n = 13) groups were administered a cyclic regimen of DP (50 mg, twice daily) or placebo. Clinical measurements and GCF sample collections were made at baseline, 2, 4, and 6 months. GCF levels of PGE 2 and IL-1β were determined using enzyme immunoassay and enzyme-linked immunoassay kits, respectively. At baseline, no significant differences existed between groups for plaque indices, gingival indices, bleeding on probing, probing depth (PD), or attachment levels (P > 0.05). Compared with the control group, cyclic regimen in the test group suppressed increased levels of PGE 2 found in GCF at the end of the study (P < 0.05). Significant differences for PD and relative attachment gain were also noted in favor of the test group (P < 0.05). These results suggest that a cyclic regimen of DP may be efficacious in the management of chronic periodontitis in adults.

Studies on the adoption and maintenance of group exercise behavior are scarce. The objective of this study is to test two self-efficacy based interventions to increase barrier self-efficacy and group exercise behavior. In total 122 participants (Mage 42.02 yr.; SD 12.29; 67% females) were recruited and randomly assigned to one control and two experimental groups. The control group was limited to participate in one virtual group exercise program only (group 1). The first experimental group was able to self-set their activities and participate in multiple group exercise programs (group 2). The second experimental group received an additional monthly coaching protocol to manage self-set goals (group 3). A validated scale for barrier self-efficacy was used, group exercise sessions were measured and drop-out rates were registered. An ANOVA indicated that mean amount of sessions of group 1 and 3, and 2 and 3 differed significantly (p < 0.05) in 12 weeks. Descriptive statistics demonstrate mean group exercise sessions over the total of 12 weeks of 2.74 (SD 4.65) in the control group; 4.75 (SD 6.08) in the first experimental group, and 12.25 (SD 9.07) for the second experimental group. Regression analysis indicated that self-efficacy at 8-weeks explained the highest variance in overall group exercise sessions (R2 = 0.18; p < 0.05). Overall drop-out rates were 88% in group 1, 78% in group 2 and 48% in group 3. The results showed that group exercise behavior can significantly be improved by a coaching protocol on self-set goals. Future research should address the effectiveness of self-set activities and self-set goals for a longer period of time and in other types of exercise programs. Key points Approximately 144 million individuals exercise in fitness clubs worldwide. About 50% participate in at least one group exercise program and 23% participate only in group exercise classes with instructor. Research on attendance and exercise behavior in fitness clubs is limited but there are strong indications that the frequencies are low. This study demonstrates that group exercise behavior in fitness clubs can be improved significantly by a coaching protocol on self-set goals based on tenets of self-efficacy theory. PMID:27274676

The complex fluctuations in heart rate variability (HRV) reflect cardiac autonomic modulation and are an indicator of congestive heart failure (CHF). This paper proposes a novel nonlinear approach to HRV investigation, the multi dynamic trend analysis (MDTA) method, based on the empirical mode decomposition algorithm of the Hilbert-Huang transform combined with a variable-sized sliding-window method. Electrocardiographic signal data obtained from the PhysioNet database were used. These data were from subjects with CHF (mean age = 59.4 ± 8.4), an age-matched elderly healthy control group (59.3 ± 10.6), and a healthy young group (30.3 ± 4.8); the HRVs of these subjects were processed using the MDTA method, time domain analysis, and frequency domain analysis. Among all HRV parameters, the MDTA absolute value slope (MDTS) and MDTA deviation (MDTD) exhibited the greatest area under the curve (AUC) of the receiver operating characteristics in distinguishing between the CHF group and the healthy controls (AUC = 1.000) and between the healthy elderly subject group and the young subject group (AUC = 0.834 ± 0.067 for MDTS; 0.837 ± 0.066 for MDTD). The CHF subjects presented with lower MDTA indices than those of the healthy elderly subject group. Furthermore, the healthy elderly subjects exhibited lower MDTA indices than those of the young controls. The MDTA method can adaptively and automatically identify the intrinsic fluctuation on variable temporal and spatial scales when investigating complex fluctuations in the cardiac autonomic regulation effects of aging and CHF.

The present study sought to examine the interactive effects of an external locus of control and interaction in a negative peer group climate on men's perpetration of physical aggression and infliction of injury toward their female intimate partners. Participants were 206 heterosexual males recruited from the metro-Atlanta community who completed self-report measures of external locus of control, involvement in a negative peer group climate, and physical aggression and infliction of injury against intimate partners during the past 12 months. Negative peer group climate was conceptualized as a peer group that displays behavior which may instigate aggressive norms, attitudes, and behaviors. Results indicated that men with an external locus of control were more likely to perpetrate physical aggression toward and inflict injury on their intimate partners if they reported high, but not low, involvement in a negative peer group climate. These results extend current research suggesting external locus of control as a risk factor for intimate partner aggression by highlighting the impact of negative peer groups. Implications and future intervention research are discussed. © The Author(s) 2014.

Protective effects of vitamin E against myocardial ischemia/reperfusion injury in rats.

To clarify the cardioprotective effects of a short course of vitamin E treatment (vit E) as compared with a nitric oxide donor, nitroglycerin (GTN) against ischemia-reperfusion induced heart injury in rats. This randomized control study was conducted in the Physiology Department, Faculty of Medicine, Ain Shams University, Cairo, Egypt from 1st June to 31 August 2009. This work was undertaken on 28 female Wistar rats weighing 150- 200 gm. Rats were allocated into 4 groups; control group (non-treated), GTN-treated group (rats received GTN intraperitoneally 25 minutes before sacrifice, in a dose of 120 ug/kg body weight), vit E-treated group (rat received vit E by oral tubal feeding 16-20 hours before sacrifice, in a dose of 250 mg/rat), and vit E and GTN-treated group (rats received vit E and GTN as in both GTN-treated group and vit E -treated group). After sacrifice, the hearts were excised and perfused in a Langendorff preparation and subjected to 30 minutes global ischemia and reperfused for 30 minutes. Following reperfusion, heart tissues were used for assessment of malondialdehyde (MDA) and nicotinamide adenine dinucleotide (NAD)+, and for histological examination. Vitamin E treatment resulted in an enhanced post-ischemic recovery of systolic function in vit E-treated groups (vit E-treated group, and vit E and GTN-treated group) compared to the control group. Post-ischemic recovery of coronary flow was enhanced in the vit E-treated group compared to the GTN-treated group. Post ischemic tissue degeneration indicators: MDA, and NAD+ indicated a cardioprotective effect of vit E. Histological study revealed marked improvement of myocytes and mitochondrial structure in the vit E-treated group as compared with the control group. Preconditioning with vit E treatment afforded substantial recovery of post-ischemic contractile, and vascular functions compared to GTN treatment, the mechanism might involve less opening of mitochondrial permeability transition during postischemic reperfusion.

To determine effects of anti-Salmonella egg yolk antibodies on shedding and antibiotic resistance of Salmonella enterica Typhimurium, newly weaned pigs were randomly assigned to six dietary treatments. These treatment groups were (i) a control (basal) diet without additives and similar diets with (ii) egg yolk powder derived from chickens challenged with Salmonella Typhimurium antigens, (iii) a commercial egg yolk powder control, (iv) apramycin for 14 days followed by carbadox, (v) oxytetracycline, or (vi) spray-dried plasma protein. Treatments were provided beginning on day 3 of the trial, and all pigs were challenged with 5 ml of 10(8) CFU/ml Salmonella Typhimurium on day 7. Fecal samples were collected on days 0, 7, 8, 12, 14, 21, 58, 88, and 118 for isolation of Salmonella and Escherichia coli to determine shedding and antibiotic resistance patterns. Body weights, white blood cell counts, and plasma concentrations of anti-Salmonella immunoglobulin G and porcine interleukin 1beta were analyzed as indicators of animal health. The percentage of pigs shedding Salmonella was lower for antibiotic treatment groups compared with other groups; however, resistance was greater in E. coli from pigs fed antibiotics than in pigs in other treatment groups. Health and performance indicators (pig weight gains, white blood cell counts, and plasma concentrations of anti-Salmonella antibodies) did not differ between treatment groups. These studies indicate that feeding egg yolk containing anti-Salmonella immunoglobulin Y may not be effective in controlling shedding of Salmonella in pigs.

The Effect of the Physical Presence of Co-Players on Perceived Ostracism and Event-Related Brain Potentials in the Cyberball Paradigm

The affective and cognitive mechanisms elicited by the experience of social exclusion—or ostracism—have recently been explored using behavioral and neurocognitive methods. Most of the studies took advantage of the Cyberball paradigm, a virtual ball tossing game with presumed co-players connected via the internet. Consistent behavioral findings indicate that exclusion obviously threatens fundamental social needs (belonging, self-esteem, meaningful existence, and control) and lowers mood. In this study, we followed the question whether the credibility of the setting affects the processing of social exclusion. In contrast to a control group (standard Cyberball setup), co-players were physically present in an experimental group. Although the credibility of the virtual ball tossing game was significantly enhanced in the experimental group, self-reported negative mood and need threat were not enhanced compared to the control group. Event-related brain potentials (ERPs), however, indicated a differential processing of social exclusion. The N2 amplitude triggered by occasional ball receptions was significantly reduced in the experimental group. This effect was restricted for an early time range (130–210 ms), and did not extend to the following P3 components. The ERP effect in the N2 time range can be related to a differential social reward processing in ostracism if co-players are physically present. The lack of a corresponding correlate in the behavioral data indicates that some facets of ostracism processing are not covered by questionnaire data. PMID:23951269

We investigated performance-derived measures of executive control, and their relationship with self- and informant reported executive functions in everyday life, in treatment-naive adults with newly diagnosed Attention Deficit Hyperactivity Disorder (ADHD; n = 36) and in healthy controls (n = 35). Sustained attentional control and response inhibition were examined with the Test of Variables of Attention (T.O.V.A.). Delayed responses, increased reaction time variability, and higher omission error rate to Go signals in ADHD patients relative to controls indicated fluctuating levels of attention in the patients. Furthermore, an increment in NoGo commission errors when Go stimuli increased relative to NoGo stimuli suggests reduced inhibition of task-irrelevant stimuli in conditions demanding frequent responding. The ADHD group reported significantly more cognitive and behavioral executive problems than the control group on the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A). There were overall not strong associations between task performance and ratings of everyday executive function. However, for the ADHD group, T.O.V.A. omission errors predicted self-reported difficulties on the Organization of Materials scale, and commission errors predicted informant reported difficulties on the same scale. Although ADHD patients endorsed more symptoms of depression and anxiety on the Achenbach System of Empirically Based Assessment (ASEBA) than controls, ASEBA scores were not significantly associated with T.O.V.A. performance scores. Altogether, the results indicate multifaceted alteration of attentional control in adult ADHD, and accompanying subjective difficulties with several aspects of executive function in everyday living. The relationships between the two sets of data were modest, indicating that the measures represent non-redundant features of adult ADHD. PMID:25545156

To report the long-term effect (18 years) of the Nexö-method, initially implemented in groups of children in Moscow in 1994. Three groups of children were included in the initial study in 1994. This study is a follow-up study of two of the three initial groups: a group of 6-year-olds (test group6 ; control group6 ) and a group of 11-year-olds (test group11 , control group11) , n = 50 individuals in each of the four subgroups. In 2012, >80% of the participants in the two groups (now aged 24 and 28 years old) were re-examined by the original examiner, who was blinded to which group the patients had belonged in the initial study. After re-examination, the participants were interviewed by a person not otherwise attached to the study. Finally, caries data were collected from 100 24-year-olds and 100 28-year-olds who attended the dental school (50%) and private clinic (50%) in Moscow (External control groups24,28 ). The outcome variables of the study were plaque and gingival status, and DMFT/S. In 2012, the control groups24,28 displayed significantly higher plaque scores than the test groups24,28 (P-values < 0.05). No differences were seen regarding gingivitis scores (P-values > 0.41). Mean DMFT/S in 2012 was test group24 = 6.98/10.51, control group24 = 8.84/13.14 (P = 0.02/0.06). External control group24 = 8.89/15.86 (test24 versus external control group24 , P = 0.01/0.007; control24 versus external control group24 , P = 0.94/0.16). Test group28 = 6.74/10.83, control group28 = 8.70/14.48 (P = 0.02/0.008). External control group28 = 9.03/18.06 (test28 versus external control28 , P = 0.03/0.001; control28 versus external control28 , P = 0.68/0.07). The interview indicated that the participants in the test groups were more aware of factors that are considered important for control of caries than participants in the control groups. The data from this group of Moscow citizens suggest a long-term positive effect of the Nexö-method implemented during childhood. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Pregnancy represents a risk factor in the occurrence of vaginal candidosis. The objectives of our study were: to make determination of the microscopic findings of vaginal swab, frequency of Candida species in the culture of pregnant women and patients who are not pregnant, determine the Candida species in all cultures, and to determine the frequency and differences in the frequency of C. albicans and other non-albicans species. In one year study performed during 2006 year, we tested patients of Gynaecology and Obstetrics clinic of the Clinical Centre in Sarajevo and Gynaecology department of the General hospital in Sarajevo. 447 woman included in the study were separated in two groups: 203 pregnant (in the last trimester of pregnancy), and 244 non-pregnant woman in period of fertility. Each vaginal swab was examined microscopically. The yeast, number of colonies, and the species of Candida were determined on Sabouraud dextrose agar with presence of antibiotics. For determination of Candida species, we used germ tube test for detection of C. albicans, and cultivation on the selective medium and assimilation tests for detection of non-albicans species. The results indicated positive microscopic findings in the test group (40,9%), as well as greater number of positive cultures (46,8%). The most commonly detected species for both groups was C. albicans ( test group 40.9% and control group 23,0%). The most commonly detected non-albicans species for the test group were C. glabrata (4,2 %) and C. krusei (3,2%), and for the control group were C. glabrata (3,2%) and C. parapsilosis (3,2%). The microscopic findings correlated with the number of colonies in positive cultures. In the test group, we found an increased number of yeasts (64,3%), and the pseudopyphae and blastopores by microscopic examination as an indication of infection. In the control group, we found a small number of yeasts (64,6%) , in the form of blastopores, as an indication of the candida colonisation. Our results indicate that gravidity, as the risc factor for incidence of infection, has the significant role in the incidence of vaginal candidosis.

Use of the Progressive Figures Test in evaluating brain-damaged children, children with academic problems, and normal controls.

This study explores the use of the Progressive Figures Test as an instrument for broad initial screening of children in the 6- through 8-year age range with respect to the possible need for more definitive neuropsychological evaluation. Considering earlier results obtained in comparison of brain-damaged and control children [Clinical Neuropsychology: Current Applications, Hemisphere Publishing Corp., Washington, DC, 1974, p. 53; Proceedings of the Conference on Minimal Brain Dysfunction, New York Academy of Sciences, New York, 1973, p. 65], the Progressive Figures Test seemed potentially useful as a first step in determining whether a comprehensive neuropsychological evaluation is indicated. In this investigation, three groups were studied: (1) children with definitive evidence of brain damage or disease who, when compared with normal controls, help to establish the limits of neuropsychological functioning, (2) a group of children who had normal neurological examinations but also had academic problems of significant concern to both parents and teachers, and (3) a normal control group. Statistically significant differences were present in comparing each pair of groups, with the brain-damaged children performing most poorly and the controls performing best. Score distributions for the three groups make it possible to identify a score-range that represented a borderline or "gray" area and to suggest a cutting score that identified children whose academic problems might have a neurological basis and for whom additional neuropsychological evaluation appeared to be indicated.

Distracted driving is a known contributor to traffic accidents, and many states have banned texting while driving. However, little is known about the potential accident risk of other common activities while driving, such as eating. The objective of the current study was to examine the adverse impact of eating/drinking behavior relative to texting and nondistracted behaviors on a simulated driving task. A total of 186 participants were recruited from undergraduate psychology courses over 2 semesters at Kent State University. We utilized the Kent Multidimensional Assessment Driving Simulation (K-MADS) to compare simulated driving performance among participants randomly assigned to texting (N = 45), eating (N = 45), and control (N = 96) conditions. Multivariate analyses of variance (MANOVA) were conducted to examine between-group differences on simulated driving indices. MANOVA analyses indicated that groups differed in simulated driving performance, F(14, 366) = 7.70, P < .001. Both texting and eating produced impaired driving performance relative to controls, though these behaviors had approximately equal effect. Specifically, both texting and eating groups had more collisions, pedestrian strikes, and center line crossings than controls. In addition, the texting group had more road edge excursions than either eating or control participants and the eating group missed more stop signs than controls. These findings suggest that both texting and eating are associated with poorer simulated driving performance. Future work is needed to determine whether these findings generalize to real-world driving and the development of strategies to reduce distracted driving.

Depression is often characterized by attentional biases toward negative items and away from positive items, which likely affects reward and punishment processing. Recent work reported that training attention away from negative stimuli reduced this bias and reduced depressive symptoms. However, the effect of attention training on subsequent learning has yet to be explored. In the current study, participants were required to learn to maximize reward during decision-making. Undergraduates with elevated self-reported depressive symptoms received attention training toward positive stimuli prior to performing the decision-making task (n=20; active training). The active training group was compared to two groups: undergraduates with elevated self-reported depressive symptoms who received placebo training (n=22; placebo training) and control subjects with low levels of depressive symptoms (n=33; non-depressive control). The placebo-training depressive group performed worse and switched between options more than non-depressive controls on the reward maximization task. However, depressives that received active training performed as well as non-depressive controls. Computational modeling indicated that the placebo-trained group learned more from negative than from positive prediction errors, leading to more frequent switching. The non-depressive control and active training depressive groups showed similar learning from positive and negative prediction errors, leading to less frequent switching and better performance. Our results indicate that individuals with elevated depressive symptoms are impaired at reward maximization, but that the deficit can be improved with attention training toward positive stimuli.

The aim of the current study was to determine the effect of a daily intake of three grams of cinnamon over eight weeks on glycemic indicators, advanced glycation end products, and antioxidant status in patients with type 2 diabetes. In a double-blind, randomized, placebo controlled clinical trial study, 44 patients with type 2 diabetes, aged 57 ± 8 years, were randomly assigned to take either a three g/day cinnamon supplement ( n = 22) or a placebo ( n = 22) for eight weeks. We measured the fasting blood glucose, insulin, hemoglobinbA1c, homeostasis model assessment for insulin resistance (HOMA-IR), carboxymethyl lysine, total antioxidant capacity, and malondialdehyde levels at the beginning and the end of the study. Thirty-nine patients (20 in the intervention group and 19 in the control group) completed the study. After an eight-week intervention, changes in the level of fasting blood glucose, insulin, hemoglobinbA1c, HOMA-IR, carboxymethyl lysine, total antioxidant capacity, and malondialdehyde were not significant in either group, nor were any significant differences between groups observed in these glycemic and inflammatory indicators at the end of the intervention. Our study revealed that cinnamon supplementation had no significant effects on glycemic and inflammatory indicators in patients with type 2 diabetes.

This study was designed to explore the complementary effects of a combination formulation of olive oil, olive and fig fruits on RA remission indicators. A randomized controlled clinical trial was designed. Adult RA patients were randomly divided into two groups receiving routine Disease-modifying antirheumatic drugs (DMARDs) regimen (control group) and routine DMARDs regimen plus the herbal supplementary formulation of olive oil, fig and olive fruits (intervention group). Patients were followed every 4 weeks for total study period of 16 weeks. In addition to demographic and medical history of the patients, the Disease Activity Score with 28-joint counts based on Erythrocyte Sedimentation Rate (DAS28_ESR) were recorded. SPSS (version 22.0) software was used to analyze data, assuming p<0.05 as significance level. 56 patients (control = 27 and intervention = 29), with mean ± sd age of 50.91 ± 12.26 years completed the study. Repeated measures analysis revealed that differences between remission indicators in the two study groups were not statistically significant, however, there was a p = 0.03 for the within-subjects contrast test of the Patient Global Assessment (PtGA), approving a nonlinear change for PtGA with respect to time. No between groups differences in adjunct drug therapy pattern for disease flares were seen. In conclusion, although, non-significant changes in the study variable of DAS28_ESR is in agreement with few previous reports, nevertheless, trends in its reduction in the intervention group along with the significant delayed PtGA score improvements occurred in the intervention group convince us to suggest further investigations on the supplementary olive and fig products, with a longer follow up periods.

A tongue pressure transducer system was used to assess tongue strength, endurance, fine pressure control and rate of repetitive movement in a group of 20 individuals, aged 17 to 60 years, with dysarthria following severe traumatic brain injury (TBI). Comparison of the TBI group's results against data obtained from a group of 20 age and sex matched control subjects revealed reductions in tongue endurance and rate of repetitive movement. Tongue strength and fine pressure control, however, were found not to differ significantly from the control group. Pearson's product-moment correlations indicated there to be only weak correlations between the physiological nonspeech tongue parameters and the deviant perceptual articulatory features exhibited by the TBI group. Further analysis of the results on an individual subject basis revealed no clear relationships between the physiological and perceptual parameters suggesting that the TBI subjects may have been compensating in different ways for the physiological impairments.

To study the relationship between the family structure and characteristics of the response to stress in adolescent addicts. The study included 65 patients who used psychoactive substances and 42 healthy controls. A set of psychological methods was used. In the group of adolescent addicts, a low result was revealed on the scale 'family cohesion'. A high level of development of such mechanisms of psychological defense as denial, suppression, repression, compensation, substitution, intellectualization and reactive education was diagnosed in both groups. Significant differences were revealed only in repression. Such stress coping strategies as self-control, escape-avoidance and problem-solving were more often used in the main group while confrontational coping, distancing, seeking social support, accepting responsibility and positive reassessment were used in the control group. Lower indices of resilience in adolescent addicts compared to the control group.

Online social networks (OSNs) are a new, promising approach for catalyzing health-related behavior change. To date, the empirical evidence on their impact has been limited. Using a randomized trial, we assessed the impact of a health-oriented OSN with accelerometer and scales on participant's physical activity, weight, and clinical indicators. A sample of 349 PeaceHealth Oregon employees and family members were randomized to the iWell OSN or a control group and followed for 6 months in 2010-2011. The iWell OSN enabled participants to connect with "friends," make public postings, view contacts' postings, set goals, download the number of their steps from an accelerometer and their weight from a scale, view trends in physical activity and weight, and compete against others in physical activity. Both control and intervention participants received traditional education material on diet and physical activity. Laboratory data on weight and clinical indicators (triglycerides, high-density lipoprotein, or low-density lipoprotein), and self-reported data on physical activity, were collected at baseline, 3 months, and 6 months. At 6 months, the intervention group increased leisure walking minutes by 164% compared with 47% in the control group. The intervention group also lost more weight than the controls (5.2 pounds compared with 1.5 pounds). There were no observed significant differences in vigorous exercise or clinical indicators between the 2 groups. Among intervention participants, greater OSN use, as measured by number of private messages sent, was associated with a greater increase in leisure walking and greater weight reduction over the study period. The study provides evidence that interventions using OSNs can successfully promote increases in physical activity and weight loss.

Osteoporosis is one of the most common problems of patients with spinal cord injuries (SCIs). The current study aimed to evaluate the antiosteoporotic effects of curcumin on densitometry parameters and biomarkers of bone turnovers among patients with SCI. The current controlled clinical trial was conducted among 100 patients with SCI referred to an outpatient clinic of rehabilitation in Ilam City, Iran, in 2013-2015. The intervention group received 110/mg/kg/day curcumin for 6 months and the control group received placebo. Bone mineral density (BMD) was measured in all patients. The level of procollagen type I N-terminal propeptide, serum carboxy-terminal telopeptide of type I collagen, osteocalcin, and bone-specific alkaline phosphates were compared before and after study. BMD indicators of lumbar, femoral neck, and total hip in the control group significantly decreased compared with the beginning of study. However, in the curcumin group, a significant increase was observed in BMD indicators of lumbar, femoral neck, and hip at the end of study compared with the beginning. There was also a significant difference between interventional and control groups for the mean BMD of femoral neck and hip at the end of study (0.718 ± 0.002 g/cm 2 vs. 0.712 ± 0.003 g/cm 2 and 0.742 ± 0.031 g/cm 2 vs. 0.692 ± 0.016 g/cm 2 , respectively). Curcumin, via modulation of densitometry indices and bone resorption markers, showed inhibitory effects on the process of osteoporosis. Treatment with curcumin was significantly associated with a decrease in the osteoporosis progression and bone turnover markers of patients with SCI after 6 months. Copyright © 2018 Elsevier Inc.

The effects of soybean oligosaccharides (SBOS) on antioxidant enzyme activities and insulin resistance in pregnant women with gestational diabetes mellitus (GDM) were investigated. Ninety-seven pregnant women with GDM were randomly divided into two groups, the control group (51 cases) and the SBOS group (46 cases). Before the group separation, the blood sugar level in patients was maintained stable by regular diet and insulin treatment. The control group was continued with the insulin treatment, while the SBOS group was treated with the combination of insulin and SBOS. Results showed that SBOS were able to reduce oxidative stress and alleviate insulin resistance in pregnant women with GDM, which indicates that SBOS may play an important role in the control of GDM complications.

To investigate the intelligence level and characteristics of cognitive structure of school-age children infected with soil-transmitted helminthes (STH) (hookworm, Ascaris lumbricoides and Trichuris trichiura). 1 031 children of 9 to 12 years old from Baishui village of Guangxi, Longzhou and Xinzhu villages of Hainan were selected for the survey. Stool samples from children were collected and examined by modified Kato-Katz method. 77 children infected with only one species (hookworm, A. lumbricoides, or T. trichiura) were used as case group and 39 healthy children as control. The cognitive ability for children were assessed by WISC-LV. A total of 378 cases with STH infection was found from 1 031 children, and the overall prevalence of STH infection was 36.7%. The prevalence of moderate and heavy STH infections was 16.8% (173/1 031). The verbal comprehension (VCI), working memory (WMI), processing speed (PSI) and full scale IQ (FSIQ) indices of case group were lower than those of control group (P < 0.05). The VCI (97.2), WMI (84.6), PSI (91.1) and FSIQ (95.4) indices in moderate/heavy infection group were lower than those in light infection group (99.2, 103.3, 88.3 and 99.1, respectively) and control group (102.0, 104.2, 91.9 and 100.1, respectively) (P < 0.05). The WMI index in hookworm infection group (83.7) was lower than that in A. lumbricoides (87.6) or T. trichiura (88.3) infection groups (P < 0.05). The PSI index of T. trichiura infection group (92.8) was lower than that of A. lumbricoides (97.3) or hookworm (94.4) infection groups (P < 0.05). The total intelligence level of STH infection children is in a normal range, or on borderline. The low VCI, WMI, PSI indices have been found in moderate/heavy STH infection children.

To observe the effects of bloodletting pricking, cupping and surrounding acupuncture on blood inflammation-related indices in patients with acute herpes zoster (HZ), and to explore the mechanism of pain control and treatment. A total of 60 patients were randomly divided into an observation group and a control group, 30 cases in each one. In the observation group, the patients were treated with bloodletting pricking at herpes, followed by cupping treatment; also the surrounding acupuncture was performed at injured skin. The treatment was given once a day and once every other day after the first 3 days; totally one-week treatment was given. In the control group, the patients were treated with intravenous drip of acyclovir and oral administration of vitamin B1 and B12, once a day for total one week. The visual analogue scale (VAS) and percentages of neutrophil, lymphocyte in peripheral and local blood were observed before and after treatment in the two groups. After treatment, the score of VAS was significantly reduced in both groups (both P < 0.05); compared with the control group, the score of VAS and the time of pain relieve were significantly improved in the observation group (P < 0.01, P < 0.05). Compared before treatment, the percentages of lymphocyte in peripheral and local blood were reduced after treatment (both P < 0.05) and the percentages of neutrophil in local blood were increased (both P < 0.05). The lymphocyte in local blood was also reduced after treatment in the control group (P < 0.05); compared with peripheral blood in the observation group and local blood in the control group, the percentages of lymphocyte in local blood were reduced (both P < 0.05). The efficacy of bloodletting pricking, cupping and surrounding acupuncture on acute herpes zoster is positive, and it can significantly lower the number of lymphocytes in the local blood and increase the number of neutrophil, which is likely to be one of the anti-virus mechanisms.

Based on comprehensive testing and educational history, children in grades 4-9 (on average 12 years) were diagnosed with dysgraphia (persisting handwriting impairment) or dyslexia (persisting word spelling/reading impairment) or as typical writers and readers (controls). The dysgraphia group (n = 14) and dyslexia group (n = 17) were each compared to the control group (n = 9) and to each other in separate analyses. Four brain region seed points (left occipital temporal gyrus, supramarginal gyrus, precuneus, and inferior frontal gyrus) were used in these analyses which were shown in a metaanalysis to be related to written word production on four indicators of white matter integrity and fMRI functional connectivity for four tasks (self-guided mind wandering during resting state, writing letter that follows a visually displayed letter in alphabet, writing missing letter to create a correctly spelled real word, and planning for composing after scanning on topic specified by researcher). For those DTI indicators on which the dysgraphic group or dyslexic group differed from the control group (fractional anisotropy, relative anisotropy, axial diffusivity but not radial diffusivity), correlations were computed between the DTI parameter and fMRI functional connectivity for the two writing tasks (alphabet and spelling) by seed points. Analyses, controlled for multiple comparisons, showed that (a) the control group exhibited more white matter integrity than either the dysgraphic or dyslexic group; (b) the dysgraphic and dyslexic groups showed more functional connectivity than the control group but differed in patterns of functional connectivity for task and seed point; and (c) the dysgraphic and dyslexic groups showed different patterns of significant DTI-fMRI connectivity correlations for specific seed points and written language tasks. Thus, dysgraphia and dyslexia differ in white matter integrity, fMRI functional connectivity, and white matter-gray matter correlations. Of clinical relevance, brain differences were observed in dysgraphia and dyslexia on written language tasks yoked to their defining behavioral impairments in handwriting and/or in word spelling and on the cognitive mind wandering rest condition and composition planning.

Several studies have demonstrated the beneficial effects of meditation on attention. The present study investigated the relationship between focused attention (FA) and open monitoring (OM) meditation skills and the various functions of attention. In Experiment 1, we executed the attention network test and compared the performance of experts on dandao meditation with that of ordinary people on this test. The results indicated that the experts specializing in OM meditation demonstrated greater attentional orienting ability compared with those specializing in FA meditation and the control group. In addition, both expert groups registered improvements in their executive control abilities compared with the control group. In Experiment 2, we trained beginners in FA meditation for 3months. The results showed that the experimental group exhibited significantly enhanced executive control ability. We infer that FA meditation skills promote executive control function and OM meditation skills promote both executive control and attentional orienting functions. Copyright © 2016 Elsevier Inc.

We studied the effects of enteral nutrition (EN) support initiated 1 week before surgery on postoperative nutritional status, immune function, and inflammatory response in gastric cancer patients. A total of 200 gastric cancer patients were randomly divided into two groups: EN starting 1 week before surgery (study group) and EN starting early after surgery (control group). The two groups received EN support, following different therapeutic schedules, until the 9th day after operation. In the patients, body weight, skinfold thickness, upper-arm circumference, white blood cell count, albumin, prealbumin, C-reactive protein, peripheral immunoglobulins (IgA, IgG, and IgM), T lymphocyte subsets, interleukin-6, and tumor necrosis factor-α were measured 10 days before and after surgery and on the first day after surgery. There was no statistically significant difference in the results of recovery time of passage of gas by anus, abdominal distension, stomachache, blood glucose, hepatic and renal functions, and electrolytes between the two groups of patients (P > 0. 05). Adverse reactions occurred to both groups at 1 and 2 days after operation. Such conditions was improved after the intravenous drip rate was adjusted. The albumin and prealbumin levels of the patients in both groups decreased at 1 day after operation (P < 0. 05). The levels rose when the research was finished (P < 0. 05). The prealbumin level of the study group was higher than that of the control group at 10 days after operation (P < 0. 05). The IgG level of the study group was higher than that of the control group at 10 days after operation (P < 0. 05). The two groups of inflammatory reaction indicators of the study group were lower than those of the control group at 10 days after operation (P < 0. 05). This study indicates that appropriate preoperative EN support for gastric cancer patients can improve their postoperative nutritional status and immune function, can reduce inflammatory response, and is more conducive to the recovery of patients.

The purpose of this study was to determine whether the occurrence of numerous colonic bubbles during CT colonography (CTC) performed with polyethylene glycol cleansing and oral iohexol fecal/fluid tagging could be prevented by use of simethicone. Adults with suspected colonic neoplasia who had been randomly assigned to control and simethicone intervention groups underwent CTC after cleansing with 4 L of polyethylene glycol, tagging with 50 mL of 350 mg I/mL oral iohexol, and without (control) or with (intervention) oral administration of 200 mg of simethicone. Colonic segments in the control and intervention groups were evaluated for amount of colonic bubbles during CTC. A 6-point grading system was used in which 0 indicated no bubbles and 5 indicated that more than three fourths of the air-distended mucosa was covered with bubbles. The primary endpoint was a per-patient colonic bubble grade, derived as an average of the segmental grades. Eighty adults with suspected colonic neoplasia were randomly assigned to the control (40 patients) and simethicone intervention (40 patients) groups. A total of 659 colonic segments in the control group and 689 segments in the intervention group were evaluated for amount of colonic bubbles during CTC. The per-patient colonic bubble score was significantly lower in the simethicone intervention group than in the control group. The mean score was 0.0±0.1 (SD) versus 1.2±0.8 (p<0.001; 95% CI for the mean difference, -1.4 to -1.0). In the intervention group, 673 (97.7%) segments were grade 0, and 16 (2.3%) were grade 1. In contrast, in the control group, 226 (34.3%) segments were grade 0; 173 (26.3%), grade 1; 175 (26.6%), grade 2; 45 (6.8%), grade 3; 23 (3.5%), grade 4; and 17 (2.6%), grade 5. The colonic bubbles associated with fecal/fluid tagging with iohexol can be successfully prevented by adding simethicone to the colonic preparation.

Working Memory and executive functioning deficits are core characteristics of patients suffering from schizophrenia. Electrophysiological research indicates that altered patterns of neural oscillatory mechanisms underpinning executive functioning are associated with the psychiatric disorder. Such brain oscillatory changes have been found in local amplitude differences at gamma and theta frequencies in task-specific cortical areas. Moreover, interregional interactions are also disrupted as signified by decreased phase coherence of fronto-posterior theta activity in schizophrenia patients. However, schizophrenia is not a one-dimensional psychiatric disorder but has various forms and expressions. A common distinction is between positive and negative symptomatology but most patients have both negative and positive symptoms to some extent. Here, we examined three groups-healthy controls, predominantly negative, and predominantly positive symptomatic schizophrenia patients-when performing a working memory task with increasing cognitive demand and increasing need for executive control. We analyzed brain oscillatory activity in the three groups separately and investigated how predominant symptomatology might explain differences in brain oscillatory patterns. Our results indicate that differences in task specific fronto-posterior network activity (i.e., executive control network) expressed by interregional phase synchronization are able to account for working memory dysfunctions between groups. Local changes in the theta and gamma frequency range also show differences between patients and healthy controls, and more importantly, between the two patient groups. We conclude that differences in oscillatory brain activation patterns related to executive processing can be an indicator for positive and negative symptomatology in schizophrenia. Furthermore, changes in cognitive and especially executive functioning in patients are expressed by alterations in a task-specific fronto-posterior connectivity even in the absence of behavioral impairment.

Opisthorchis viverrini infection induces chronic inflammation in the bile ducts, leading to periductal fibrosis (PDF), which possibly associates to cholangiocarcinoma (CCA). Patients with CCA have a poor prognosis, which is linked to asymptomatic disease and late diagnosis. Hence, detecting early stage CCA is essential. Secretory miRNAs have been promoted as biomarkers for pathological changes associated with parasitic infections, fibrosis and/or cancer. We aimed to determine levels of miR-192 and miR-21 in the urine of O. viverrini infected, periductal fibrosis (PDF) and CCA groups using qRT-PCR. We found that miR-192 was significantly higher in O. viverrini infected, PDF and also CCA groups (p<0.05) than in healthy controls. By utilizing the Receiver Operation Characteristics (ROC) analysis, miR-192 differentiated patients with opisthorchiasis (the area under the curve; AUC=0.766), PDF subjects (AUC=0.781) and CCA patients (AUC=0.682) from healthy controls. MiR-21 was significantly higher in PDF and CCA groups (p<0.05) than in healthy controls. MiR-21 discriminated PDF subjects (AUC=0.735) and CCA patients (AUC=0.682) from healthy controls. Combined levels of these two miRNAs revealed an increased AUC of 0.812 for separating opisthorchiasis, AUC of 0.815 in discriminating PDF subjects, and AUC of 0.849 in differentiating CCA from healthy controls. Odds ratios (OR) indicated high levels of miR-192/miR-21 as risk predictors for opisthorchiasis, PDF and CCA. Levels of these miRNAs declined significantly for patients following praziquantel treatment. In conclusion, urinary miR-192/miR-21 have potential as risk indicators for opisthorchiasis and PDF-associated CCA in the endemic region. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Bacteremia and systemic inflammatory markers are associated with periodontal and systemic diseases and may be linking mechanisms between these conditions. We hypothesized that in the development of gingival inflammation, systemic markers of inflammation and bacteremia would increase. To study the effect of bacteremia on systemic inflammatory markers, we recruited 80 subjects to participate in an experimental gingivitis study. Subjects were stratified based on gender, smoking and the number of bleeding sites and then randomized to one of two groups: control group (n = 40) or experimental gingivitis group (n = 40). Subjects in the control group conducted an oral hygiene regimen: brushing twice daily with a regular sodium fluoride cavity protection dentifrice and a standard manual toothbrush, flossing twice daily, and mouth rinsing with an anti-cavity fluoride rinse once daily. The experimental group stopped brushing and flossing, and used only the fluoride anti-cavity mouth rinse for 21 d. Seventy-nine of 80 subjects were evaluable. One subject in the control group was excluded from the results due to antibiotic use during the study. Our data showed the experimental gingivitis group exhibited a significant (p < 0.05) increase in dental plaque level and gingival inflammatory indices relative to baseline and the control group but a decrease in bacteremia and soluble intercellular adhesion molecule-1 levels vs. baseline. Bacteremia was negatively correlated with gingival inflammatory indices and soluble intercellular adhesion molecule-1 levels in the experimental gingivitis group, thus negating our hypothesis. We conclude that there are marked differences in systemic cytokine levels over the course of short-term experimentally induced gingivitis and further conclude that a long-term periodontitis study must be considered to address mechanisms whereby oral diseases may affect systemic diseases. © 2015 John Wiley & Sons A/S.

Periodontal subgingival pathogens affect local and systemic immune responses and initiate an acute phase systemic inflammatory response characterized by the release of C-reactive proteins (CRPs). This study has been carried out to evaluate the serum concentration of CRPs, which can be used as a marker of periodontal disease as well as a risk indicator for cardiovascular diseases. In a retrospective study a total number of 45 subjects were selected from the outpatient department of periodontics a mean age of 40 years. Based on the periodontal status, the subjects were divided into 3 groups of 15 subjects each. Group I: Control group [with attachment loss (AL) ≤ 2 mm and pocket depth (PD) < 3 mm], Group II: Generalized aggressive periodontitis (AL ≤ 5 mm), Group III: chronic periodontitis (AL ≥ 2 mm, PD ≥ 5 mm), which includes moderate and severe periodontitis. The clinical parameters recorded were plaque index,gingival index, bleeding index, probing PD, and clinical attachment levels and scoring was done on 6 surfaces of all teeth. For the CRP assessment, blood samples were collected from subjects at the time of clinical examination. Analysis of covariance was used for comparison of mean values between the groups to adjust the ages (P value < 0.05). Overall, the mean CRP levels were high in subjects with generalized aggressive and chronic periodontitis compared with controls. This was found to be statistically significant. A statistically significant difference (P = 0.012) was found in the CRP level between groups I and II and between groups II and III, and between groups I and III. The results of the present study indicated an increase in serum CRP levels in subjects with generalized aggressive periodontitis and chronic periodontitis as compared with the controls.

Cimetidine is widely used for the treatment of digestive tract ulcers, but it induces testis injury. To explore the mechanisms underlying cimetidine-induced toxicity towards the testis, the effects of oral cimetidine on the reproductive system of male rats were assessed. Cimetidine was orally administered to male rats at 20, 40 or 120 mg/kg/day for 9 weeks. The rats were then euthanized, and serum, testis, epididymis, prostate gland, seminal vesicle, preputial gland, levator ani muscle and sphincter ani samples were collected. Sperm parameters were obtained by computer-assisted sperm analysis. Serum hormone levels were measured by ELISA. Protein expression levels were detected by immunohistochemistry. Apoptosis was assessed with the DeadEnd™ Colorimetric Apoptosis Detection System. The results indicated that the sperm average path velocity, straight line velocity and curvilinear velocity were significantly decreased in the 120 mg/kg cimetidine group compared with the control group, while luteinizing hormone and testosterone levels were significantly higher compared with the control group. Testicular lesions were observed by histopathology in the 120 mg/kg cimetidine group. The amounts of cells positive for cyclooxygenase-2 (COX-2) and nuclear factor κB (NF-κB) were increased in the 120 mg/kg cimetidine group compared with the control group. The amounts of cells positive for iNOS were increased in all cimetidine treatment groups. In addition, apoptotic cells were significantly more abundant in the 120 mg/kg cimetidine group compared with the control group, as indicated by terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling. Overall, 9 weeks of oral cimetidine induced pathological changes in the testicles and hormone secretion disorder in rats. COX-2, iNOS and NF-κB upregulation and induction of apoptosis may be associated with the reproductive toxicity caused by cimetidine.

To observe the change in serum levels of alanine aminotransferase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), direct bilirubin (DBL), indirect bilirubin (IBIL), albumin (ALB) and globulin (GLB), and mouse liver ultrastructure during 1-16 weeks of albendazole treatment. 180 female Kunming mice were divided randomly into albendazole treatment group and negative control group. Each mouse of albendazole treatment group was treated with 136.3 mg/(kg x d) albendazole. The mice in control group were given same amount of physiological saline. After 1, 2, 4, 6, 8, 10, 12, 14 and 16 weeks of treatment, 10 mice from each group were randomly selected, serum samples were collected and analyzed for the above seven liver function indices. Pathological changes of liver were observed by transmission electron microscopy. Linear regression analysis was conducted for the relationship between liver function indices(dependent variable) and pathological scores (independent variable). During 1-16 weeks of albendazole treatment, there was no significant difference in serum levels of DBL, IBIL, ALB and GLB between albendazole treatment group and control group. Compared with other treatment period, after 12 weeks of treatment the serum levels of ALT (55.2 +/- 23.7), AST(176.4 +/- 49.2) and ALP(141.1 +/- 19.4) in albendazole treatment group were higher than that of the control (35.5 +/- 8.6, 108.2 +/- 21.9, 84.0 +/- 24.8) (P < 0.05). After 2, 8, 10, 12 and 14 weeks of treatment, the pathological score of albendazole treatment group was 11.8 +/- 4.8, 10.6 +/- 4.8, 13.6 +/- 3.5, 29.8 +/- 10.7, and 5.6 +/- 2.5, respectively, which was higher than that of the control (0.8 +/- 0.4, 1.2 +/- 0.8, 2.4 +/- 2.0, 1.2 +/- 0.4, 1.4 +/- 1.1) (P < 0.05). Among the three liver function indices AST, ALT and ALP, AST was the best fit index for linear regression. The regression formula was Y = -17.616 + 0.188X. Long-term treatment with albendazole at a dosage of 136.3 mg/(kg x d) for mice can cause significant elevation of serum levels of ALT, AST and ALP, and result in mild pathological changes in the liver.

Background In recent years, armed conflicts in the Middle East have resulted in high rates of exposure to traumatic events. Despite the increasing demand of mental health care provision, ongoing violence limits conventional approaches of mental health care provision. Internet-based interventions for posttraumatic stress disorder (PTSD) have proved feasible and effective in Western countries, but their applicability and efficacy in war and conflict regions remains unknown. Objective This study investigated the efficacy of a cognitive behavioral Internet-based intervention for war-traumatized Arab patients, with focus on Iraq. Methods A total of 159 individuals with PTSD participated in a parallel group randomized trial. Participants were randomly allocated by a computer-generated sequence to a treatment group (n=79) or a waiting list control group (n=80). The treatment group received 2 weekly 45-minute cognitive behavioral interventions via Internet over a 5-week period (10 sessions in total). The primary outcome was recovery from posttraumatic stress symptoms. Results Posttraumatic stress symptoms were significantly reduced from baseline to posttreatment (intention-to-treat analysis) in the treatment group relative to the control group (F1,157=44.29, P<.001, d=0.92). Treatment effects were sustained at 3-month follow-up. Completer analysis indicated that 29 of 47 patients (62%) in the treatment group had recovered from posttraumatic stress symptoms at posttreatment (reliable change and Posttraumatic Stress Diagnostic Scale score <20) versus 1 patient (2%) in the control group (OR 74.19, 95% CI 9.93-585.8, P<.001) indicating that the chance of recovering was 74.19 times higher in the treatment than in the control group. Conclusions The results indicate, even in unstable and insecure settings with ongoing exposure to human rights violations through war and dictatorships, people with posttraumatic stress symptoms benefit from a cognitive behavioral treatment provided entirely through the Internet. This method of delivery could improve patients’ access to humanitarian aid in the form of e-mental health services.

2012-05-01

The field of personality disorders has had a long-standing interest in understanding interactions between emotion and inhibitory control, as well as neurophysiological indices of these processes. More work in particular is needed to clarify differential deficits in offenders with antisocial personality disorder (APD) who differ on psychopathic traits, as APD and psychopathy are considered separate, albeit related, syndromes. Evidence of distinct neurobiological processing in these disorders would have implications for etiology-based personality disorder taxonomies in future psychiatric classification systems. To inform this area of research, we recorded event-related brain potentials during an emotional-linguistic Go/No-Go task to examine modulation of negative emotional processing by inhibitory control in three groups: psychopathy (n = 14), APD (n = 16), and control (n = 15). In control offenders, inhibitory control demands (No-Go vs. Go) modulated frontal-P3 amplitude to negative emotional words, indicating appropriate prioritization of inhibition over emotional processing. In contrast, the psychopathic group showed blunted processing of negative emotional words regardless of inhibitory control demands, consistent with research on emotional deficits in psychopathy. Finally, the APD group demonstrated enhanced processing of negative emotion words in both Go and No-Go trials, suggesting a failure to modulate negative emotional processing when inhibitory control is required. Implications for emotion-cognition interactions and putative etiological processes in these personality disorders are discussed.

To examine the effect of a Chinese medicinal herbal formula (Feitai Capsule, ) on the quality of life (QOL) and progression-free survival (PFS) of patients with unresectable non-small cell lung cancer (NSCLC). Sixty-two patients were randomly divided into the treatment group (31 cases) and the control group (31 cases). For the treatment group, 4 capsules (1.2 g/capsule) of Feitai Capsule were administered 3 times a day after meals for 3 weeks; then no drug was administered for 1 week. This schedule was continued for at least 3 more cycles (12 weeks totally). If there were no obvious toxic reactions, the treatment was extended. The patients were evaluated at least once every 8 weeks until progressive disease (PD). For the control group, the regular follow-up and evaluation were performed at least once every 8 weeks until PD. Clinical symptoms, objective response, physical constitution and energy, QOL, and PFS were evaluated regularly. Analysis of variance (ANOVA), a non-parametric test, and analysis of covariance were used to compare clinical features, amelioration of clinical symptoms, physical constitution and energy, and QOL. Kaplan-Meier analysis was used to compare the two-group PFS. Sixty patients finished the final evaluation, with 30 patients in each group. Baseline characters between groups were not significantly different (P>0.05). The control group had a 36.7% improvement in clinical symptoms, while the treatment group had a 73.3% improvement. This difference was statistically significant (Z= -2.632, P=0.008). The control group had a 26.7% improvement in the Karnofsky performance status (KPS), while the treatment group had a 53.4% improvement. This was also significantly different (Z=-2.182, P=0.029). A comparative analysis indicated a positive correlation (r=0.917, P<0.001). Compared with the control group, QOL in the treatment group was significantly improved, except in the social/family condition and doctor-patient relationship indicators. The PFS of the treatment group and control group were 6.23 months and 4.67 months, respectively (P=0.048). Feitai Capsule, a Chinese medicinal herbal treatment could improve the QOL and extend the PFS of the unresectable NSCLC patients.

Despite the fact that the recommendations of counteracting obesity advocate for changing lifestyle and physical activity habits, the prevalence of obesity continues to rise. The aim of the study was to investigate the effect of omega-3 PUFAs supplementation with lifestyle modification on anthropometric indices and Vo2max in overweight women. Fifty overweight women aged between 20 to 45 years were recruited in this interventional study. Women randomly were divided into two experimental groups (n = 25). Group 1 received omega-3 supplement, aerobic exercise program, and a healthy diet education. Group 2 was similar to group 1, except in that patients received placebo instead of omega-3 capsules. Experimental and placebo group subjects were asked to take one supplementary capsule every day, for 8 weeks. Anthropometric indices were measured in the fourth and eighth weeks of the trial. The maximum aerobic capacity (Vo2max) was determined using a gas analysis device. The level of significance for comparing the results before and after the trial was considered at P < 0.05. According to the data, body weight, body fat percentage, waist circumference, and abdominal skinfold thickness significantly reduced in the omega-3 treated group compared to the control group during 8 weeks after the initiation of the study (P < 0.05). In addition, supplementation of omega-3, significantly improved the VO2max outcome compared to that of the control group (P = 0.03). According to the results, it seems that omega-3 PUFAS supplementation with lifestyle modification has positive effects on anthropometric indices and Vo2max in overweight women.

Caring for a person with a mental illness can have adverse effects on caregivers; however, little is known about how best to help such caregivers. The aim of the present study was to examine the efficacy of a cognitive behaviour therapy-guided self-help manual in increasing resilience in caregivers of individuals with depression, in comparison to caregivers who receive routine support only. A randomized, controlled trial was conducted, following CONSORT guidelines, with 54 caregivers allocated to parallel intervention (self-help manual) (n = 27) or control (standard support) (n = 27) groups. Resilience was assessed at baseline, post-test (week 8), and follow up (week 12). Intention-to-treat analyses were undertaken. Repeated-measures ANOVA indicated a significant difference in resilience scores between the three time points, showing a large effect. Pairwise comparisons between intervention and control groups indicated resilience to be significantly different between baseline and post-test, and between baseline and follow up, but not between post-test and follow up. Overall, the intervention group showed a slightly greater increase in resilience over time than the control group; however, the time-group interaction was not significant. Guided self-help is helpful in improving caregivers' resilience and could be used as an adjunct to the limited support provided to carers by mental health nurses and other clinicians. © 2016 Australian College of Mental Health Nurses Inc.

The aim of this study was to evaluate whether a shortened-length session of CogMed Working Memory Training (CWMT) would be a suitable active control group and evaluate study protocol to aid in design refinements for a larger randomized controlled trial (RCT). Thirty-eight post-secondary students diagnosed with ADHD were randomized into 25 sessions of standard (45 min/session) or shortened (15 min/session) CWMT, or into a waitlist control group. There was no significant difference in completion rate or training index score between the standard- and shortened-length groups indicating that both groups showed improvement and put forth good effort during training. Preliminary findings suggest that shorter training sessions may induce similar levels of engagement, motivation, and expectancy of improvement in participants. We conclude that a larger scale RCT that utilizes shortened-length training as an active control group is warranted, but that a few modifications to the study protocol will be required.

Hookah smoking during pregnancy is a health concern which requires effective interventions. Thus, the authors have aimed to evaluate the effect of motivational interviewing on craving and dependence on hookah in pregnant women (n = 140) addicted to hookah who reside in the outskirts of Zahedan, a city in southeast of Iran. The subjects were selected using the convenience sampling and randomly divided into either the control or intervention group. The intervention group received five motivational interviewing group sessions about hookah smoking withdrawal, whereas the control group was given the conventional recommendations for quitting hookah. Data were collected after eight weeks during the post intervention period using Hookah Craving Test and Hookah Addiction Severity Index. Next, they were analyzed using independent t-test, paired t-test, and analysis of covariance (ANCOVA). After the motivational interviewing intervention, the independent t-test indicated a significant difference between the intervention and control groups in terms of the mean score of hookah craving (P = 0.0001). Moreover, ANCOVA, with control of the effect of pretest and duration of hookah addiction, demonstrated a significant difference between the two groups regarding the mean score of hookah dependence after the intervention (P = 0.0001). Motivational interviewing had a significant positive impact on decreased hookah craving and dependence (two indices of withdrawal). Therefore, healthcare providers are recommended to incorporate motivational interviewing-based education into prenatal care programs to promote the chance of hookah smoking withdrawal.

Prokaryotic expression technology was used to express maltose-binding protein binding myostatin (MSTN) propeptide fusion protein. Six disease-free Altay lambs were used in this study. The right leg gastrocnemii were injected with MSTN recombinant propeptide protein. The left leg gastrocnemii (the control group) were injected with the same dose of phosphate based saline. The lambs were fed during four months under the same conditions and then slaughtered. Gastrocnemius samples were hematoxylin-eosin stained and the size of the muscle fibers was measured. A real-time polymerase chain reaction (RT-PCR) showed that single gastrocnemius cells in the experimental group had an average area of 1163.01 µm(2), while it was 845.09 µm(2) in the control group (P < 0.05). This indicates that the MSTN propeptide biological agents had an inhibitory effect on MSTN. In order to reveal its mechanism, RT-PCR was conducted to detect the expression of the differentiation-associated genes MyoD, Myf5, Myogenin, p21, and Smad3. The results showed that, in the MSTN propeptide biological agent injected group, expression levels of MSTN, Smad3, and p21 were lower than the control group, while Myf5, MyoD, and Myogenin were higher compared to the control group. This indicates that, when expression of the MSTN gene was inhibited, muscle cell differentiation and growth can be promoted by Smad3 up-regulated expression of Myf5, MyoD, and Myogenin.

The purpose of the present investigation was to determine if the salivary counts of 40 common oral bacteria in subjects with an oral squamous cell carcinoma (OSCC) lesion would differ from those found in cancer-free (OSCC-free) controls. Unstimulated saliva samples were collected from 229 OSCC-free and 45 OSCC subjects and evaluated for their content of 40 common oral bacteria using checkerboard DNA-DNA hybridization. DNA counts per ml saliva were determined for each species, averaged across subjects in the 2 subject groups, and significance of differences between groups determined using the Mann-Whitney test and adjusted for multiple comparisons. Diagnostic sensitivity and specificity in detection of OSCC by levels of salivary organisms were computed and comparisons made separately between a non-matched group of 45 OSCC subjects and 229 controls and a group of 45 OSCC subjects and 45 controls matched by age, gender and smoking history. Counts of 3 of the 40 species tested, Capnocytophaga gingivalis, Prevotella melaninogenica and Streptococcus mitis, were elevated in the saliva of individuals with OSCC (p < 0.001). When tested as diagnostic markers the 3 species were found to predict 80% of cancer cases (sensitivity) while excluding 83% of controls (specificity) in the non-matched group. Diagnostic sensitivity and specificity in the matched group were 80% and 82% respectively. High salivary counts of C. gingivalis, P. melaninogenica and S. mitis may be diagnostic indicators of OSCC.

The efficacy of oxytetracycline hydrochloride (OTC-HCl) in controlling external columnaris disease caused by Flavobacterium columnare on fingerling walleyes Sander vitreus and channel catfish Ictalurus punctatus was evaluated in two on-site hatchery trials. Microscopic examination of skin scrapings before treatment confirmed the presence of bacteria with characteristics indicative of F. columnare.in separate trials, walleyes (4.4 g) and channel catfish (1.5 g) were exposed to 60-min static bath treatments of OTC-HCl at 0, 10, and 20 mg/L (walleyes) or 0, 10, 20, and 40 mg/L (channel catfish) on three consecutive days. Each treatment regimen was tested in triplicate, and each replicate contained either 30 walleyes or 55 channel catfish. Posttreatment presumptive disease diagnosis indicated that F. columnare was the disease agent causing the mortality in both species of fish. Walleye survival at 10 d posttreatment was greater in the 10- and 20-mg/L treatment groups than in the control group; however, only the 10-mg/L treatment significantly (P < 0.05) increased walleye survival in comparison with controls. In the channel catfish trial, survival at 10 d posttreatment was significantly (P < 0.05) greater for all OTC-HCl treatment groups relative to controls. Results from these trials indicated that OTC-HCl treatments effectively reduced mortality in walleyes (10 mg/L only) and channel catfish infected with F. columnare. ??

This study aimed to determine the effect of dietary cation and anion difference (DCAD) on milk production and body fluid distribution in lactating dairy goats. Ten dairy goats were selected and divided into two groups, five animals each. Animals received either control DCAD (control, 22.81 mEq/100 g dry matter (DM)) or high DCAD (DCAD, 39.08 mEq/100 g DM). The results indicated that rectal temperature (Tr), respiration rate, milk yield and compositions did not differ between groups. But the percentage change of Tr from the DCAD group was lower than the control group between 09.00 and 13.00 hours. DM intake tended to increase in the DCAD group. Dairy goats in the DCAD group drank more water, but urinary excretion and plasma antidiuretic hormone concentration remained unchanged. Apparent water balance was higher from the DCAD group over 24 h. There was no effect of DCAD on plasma and blood volumes, but tended to increase in extracellular fluid and thereby increased total body water. The present results indicate that animals supplemented with high DCAD increase their total body water and apparent water balance. These results have contributed to the process of adaptation for evaporative cooling and would be useful in slowing down the elevation in Tr. © 2017 Japanese Society of Animal Science.

This study aimed to investigate the effects of a two-day forest therapy program on individuals with chronic widespread pain. Sixty one employees of a public organization providing building and facilities management services within the Seoul Metropolitan area participated in the study. Participants were assigned to an experimental group (n = 33) who participated in a forest therapy program or a control group (n = 28) on a non-random basis. Pre- and post-measures of heart rate variability (HRV), Natural Killer cell (NK cell) activity, self-reported pain using the visual analog scale (VAS), depression level using the Beck Depression Inventory (BDI), and health-related quality of life measures using the EuroQol Visual Analog Scale (EQ-VAS) were collected in both groups. The results showed that participants in the forest therapy group, as compared to the control group, showed physiological improvement as indicated by a significant increase in some measures of HRV and an increase in immune competence as indicated by NK cell activity. Participants in the forest therapy group also reported significant decreases in pain and depression, and a significant improvement in health-related quality of life. These results support the hypothesis that forest therapy is an effective intervention to relieve pain and associated psychological and physiological symptoms in individuals with chronic widespread pain.

The importance of quality assurance in cancer screening has recently gained increasing attention in Japan. To evaluate and improve quality, checklists and process indicators have been developed. To explore effective methods of enhancing quality in cancer screening, we started a randomized control study of the methods of evaluation and feedback for cancer control from 2009 to 2014. We randomly assigned 1270 municipal governments, equivalent to 71% of all Japanese municipal governments that performed screening programs, into three groups. The high-intensity intervention groups (n = 425) were individually evaluated using both checklist performance and process indicator values, while the low-intensity intervention groups (n= 421) were individually evaluated on the basis of only checklist performance. The control group (n = 424) received only a basic report that included the national average of checklist performance scores. We repeated the survey for each municipality's quality assurance activity performance using checklists and process indicators. In this paper, we report our study design and the result of the baseline survey. The checklist adherence rates were especially low in the checklist elements related to invitation of individuals, detailed monitoring of process indicators such as cancer detection rates according to screening histories and appropriate selection of screening facilities. Screening rate and percentage of examinees who underwent detailed examination tended to be lower for large cities when compared with smaller cities for all cancer sites. The performance of the Japanese cancer screening program in 2009 was identified for the first time.

Little is known about the trace element profile differences between Schizophrenia patients and healthy controls; previous studies about the association of certain elements with Schizophrenia have obtained conflicting results. To identify these differences in the Han Chinese population, inductively coupled plasma-mass spectrometry was used to quantify the levels of 35 elements in the sera of 111 Schizophrenia patients and 110 healthy participants, which consisted of a training (61/61 for cases/controls included) and a test group including remaining participants. An orthogonal projection to latent structures model was constructed from the training group (R(2)Y = 0.465, Q(2)cum = 0.343) had a sensitivity of 76.0% and a specificity of 71.4% in the test group. Single element analysis indicated that the concentrations of cesium, zinc, and selenium were significantly reduced in patients with Schizophrenia in both the training and test groups. The meta-analysis including 522 cases and 360 controls supported that Zinc was significantly associated with Schizophrenia (standardized mean difference [SMD], -0.81; 95% confidence intervals [CI], -1.46 to -0.16, P = 0.01) in the random-effect model. Information theory analysis indicated that Zinc could play roles independently in Schizophrenia. These results suggest clear element profile differences between patients with Schizophrenia and healthy controls, and reduced Zn level is confirmed in the Schizophrenia patients.

This study presents the reported outcomes of a two-year, part-time Masters' programme in human relations using an experiential learning methodology based mainly on humanistic psychological theory. The following hypotheses were examined. That as a result of the two-year programme: the experience of reported stress would be reduced; reported attitudes to student classroom control would shift from custodial to humanistic; there would be an increase in reports from participants of a sense of control over their lives; changes of behaviour in work, social settings and at home related to these three variables would be reported. Involved in the study were 42 experienced teachers. These included 32 women and 10 men, with an average age of 35, who worked in a wide range of educational institutions. Their learning style preferences were also considered as independent variables. A control group of 42 was established with similar demographic characteristics. Prior to the course, the experimental group and the control group were given the Maslach Burnout Inventory and the Pupil Control Ideology Form. In the early stages of the course, the experimental group completed the Kolb Learning Style Inventory and an informal measure of locus of control which was repeated at the end of the first year of the course. A sample of 32 from the experimental group were given semi-structured interviews relating to changes in their professional and personal lives. The results indicated that, following the training, there was a reduction in reported stress, indications of a more humanistic orientation towards pupil control and an increase in a sense of an internal locus of control. The quantitative data were confirmed by qualitative data generated from semi-structured interviews, which involved substantial reports of applications of the training in their professional and personal lives. These results provide support for including experiential human relations training as part of both the in-service and initial teacher training programmes.

The usefulness and the impact of Direct Healthcare Professional Communications (DHPCs, or 'Dear Doctor letters') in changing the clinical behaviour of physicians have been debated. Changes in the current risk communication methods should preferably be based on the preferences of the healthcare professionals, to optimize the uptake of the message. The aim of this study was to assess whether safety issues are communicated more effectively with an additional e-mail sent by the Dutch Medicines Evaluation Board (MEB) than with the DHPC only. A randomized controlled trial was conducted amongst ophthalmologists and hospital pharmacists in the Netherlands, who were the target group of a DHPC that was issued for pegaptanib, a drug that is administered intra-ocularly in patients with macular degeneration. The intervention group (N = 110) received the pegaptanib DHPC, as well as the MEB e-mail. The control group (N = 105) received the traditional paper-based DHPC only. Two weeks later, the study population received an invitation to fill out an online questionnaire. Questions were asked about the respondents' knowledge and attitude regarding the pegaptanib issue, and any action they had consequently taken. Additional questions were asked about their satisfaction with the DHPC and the e-mail, and their preferred source of such information. Forty respondents (18.6%) completed the questionnaire. Eighty-one percent of the respondents in the intervention group (N = 21) and 47% of the control group (N = 19) correctly indicated that a serious increase in intra-ocular pressure could be caused by pegaptanib injections (Fishers' exact test, p = 0.046). Nine respondents in the intervention group versus none of the control group respondents indicated that they had taken action in response to the pegaptanib safety issue (Fishers' exact test, p = 0.01). The majority of both the intervention group and the control group confirmed that they would like to receive an MEB e-mail with safety information about drugs in the future (90 and 95 %, respectively). The results of this study indicate that an additional e-mail might strengthen the uptake of the safety information provided to healthcare professionals, who prefer to receive an e-mail from the MEB as a source of such information, as well as the DHPC. This study may serve as a starting point for new strategies to improve risk communication regarding safety issues associated with drugs and its impact on prescribing.

MMPI scores for items on the Harris and Lingoes (1955, 1968) subscales HY2 (need for affection) and PA2 (naivete) were compared among pedophiles (n = 50), non-sexually deviant psychiatric patients (n = 25), and a general control group (n = 50). Results indicated that pedophiles did not demonstrate a "naive need for affection," but, rather, a cynical need for affection. Scores on the Pedophelia (PE) Scale (Toobert, Bartelme, & Jones, 1959) also were compared, and no significant differences were found between the pedophiles and either control group, although a difference was found between the scores of the psychiatric control group and those of the general sample. Selected items from scale 4 (Psychopathic Deviate) and scale 9 (Hypomania) also produced no significant differences among groups.

Affect-regulated exercise to feel 'good' can be used to control exercise intensity amongst both active and sedentary individuals and should support exercise adherence. It is not known, however, whether affect-regulated exercise training can lead to physical health gains. The aim of this study was to examine if affect-regulated exercise to feel 'good' leads to improved fitness over the course of an 8-week training programme. A repeated measures design (pretest-posttest) with independent groups (training and control). 20 sedentary females completed a submaximal graded exercise test and were then allocated to either a training group or control group. The training group completed two supervised sessions and one unsupervised session per week for 8 weeks. Exercise intensity was affect-regulated to feel 'good'. Following the 8 weeks of training, both groups completed a second submaximal graded exercise test. Repeated measures analyses of variance indicated a significant increase in the time to reach ventilatory threshold in the training group (318 ± 23.7s) compared to control (248 ± 16.9s). Overall compliance to training was high (>92%). Participants in the training group exercised at intensities that would be classified as being in the lower range of the recommended guidelines (≈ 50% V˙O(2) max) for cardiovascular health. Affect-regulated exercise to feel 'good' can be used in a training programme to regulate exercise intensity. This approach led to a 19% increase in time to reach ventilatory threshold, which is indicative of improved fitness. Copyright © 2012 Sports Medicine Australia. Published by Elsevier Ltd.

To evaluate the theory of mind in autism spectrum disorders (ASD) and control individuals by applying the Strange Stories test that was translated and adapted to the Portuguese language. Twenty-eight children with ASD and 56 controls who were all male and aged between 6 and 12 years participated in the study. There were significant differences between the median scores of the groups for each of the 12 stories of the test and for the sum total of all the median scores. The median scores for all stories were significantly greater in the control group than those in the experimental group (children with ASD). In addition, the protocol had excellent internal consistency. The theory of mind skills assessed with the Strange Stories test indicated alterations in children with ASD compared with children in the control group.

The purpose of this article is to investigate the effect of Opuntia stricta H (Cactaceae) extract on suppression of hypertrophic scar on ventral surface wounds of rabbit ears. Full thickness skin defection was established in a rabbit ear to simulate hypertrophic scar. Opuntia extract was sprayed on the wounds in the experimental group, and normal saline was used in the control group. After the wounds healed with scar formation, the hypertrophic scar tissue was harvested on days 22, 39, and 54 for histological analysis. The expression of type I and type III collagen and matrix metalloproteinase-1 (MMP-1) were evaluated by immunohistochemistry and real-time quantitative polymerase chain reaction. The results indicated that the scar of the control group is more prominent compared with the opuntia extract group. The expression of type I collagen in the opuntia extract group was lower than the control group, while type III collagen in opuntia extract group gradually increased and exceeded control group. The expression of MMP-1 decreased in the opuntia extract group, while the control group increased over time, but the amount of MMP-1 was much higher than that in the control group on day 22. In conclusion, opuntia extract reduces hypertrophic scar formation by means of type I collagen inhibition, and increasing type III collagen and MMP-1.T he novel application of opuntia extract may lead to innovative and effective antiscarring therapies. © The Author(s) 2015.

A randomized controlled trial was conducted to determine the effect of 6 months of whole body vibration (WBV) exercise on physical function in postmenopausal osteoporotic women treated with alendronate. Fifty-two ambulatory postmenopausal women with osteoporosis (mean age: 74.2 years, range: 51-91 years) were randomly divided into two groups: an exercise group and a control group. A four-minute WBV exercise was performed two days per week only in the exercise group. No exercise was performed in the control group. All the women were treated with alendronate. After 6 months of the WBV exercise, the indices for flexibility, body balance, and walking velocity were significantly improved in the exercise group compared with the control group. The exercise was safe and well tolerated. The reductions in serum alkaline phosphatase and urinary cross-linked N-terminal telopeptides of type I collagen during the 6-month period were comparable between the two groups. The present study showed the benefit and safety of WBV exercise for improving physical function in postmenopausal osteoporotic women treated with alendronate.

The aim of this study was to evaluate the effects of a smoking cessation education on endothelial function and carboxyhemoglobin levels in smokers with variant angina. A nonequivalent control group pretest-posttest design was used. Participants were 60 male smokers with variant angina admitted to one hospital: the control group (30) between September and December, 2009, and the experimental group (30) between February and May, 2010. Endothelial function, as defined by flow-mediated vasodilation (FMD) of the brachial artery, and serum carboxyhemoglobin (COHb) were determined at baseline and at 3 months after the initiation of education in both groups. Three months after the program, smoking cessation was successful in 22 of the 30 smokers in the experimental group, but only in 4 of 30 smokers in the control group (p<.001). After the education, the experimental group showed a significant increase in FMD, and a significant decreased in serum COHb compared with the control group. The findings indicate that this smoking cessation education program is effective for hospitalized smokers with variant angina.

A randomized controlled trial to investigate the impact of a low glycemic index (GI) diet on body mass index in obese adolescents

PubMed Central

2014-01-01

Background The role of a low glycemic index (GI) diet in the management of adolescent obesity remains controversial. In this study, we aim to evaluate the impact of low GI diet versus a conventional Chinese diet on the body mass index (BMI) and other obesity indices of obese adolescents. Methods Obese adolescents aged 15–18 years were identified from population-recruited, territory-wide surveys. Obesity was defined as BMI ≥95th percentile of Hong Kong local age- and sex-specific references. Eligible subjects were randomized to either an intervention with low GI diet (consisting of 45-50% carbohydrate, 30-35% fat and 15-20% protein) or conventional Chinese diet as control (consisting of 55-60% carbohydrate, 25-30% fat and 10-15% protein). We used random intercept mixed effects model to compare the differential changes across the time points from baseline to month 6 between the 2 groups. Results 104 obese adolescents were recruited (52 in low GI group and 52 in control group; 43.3% boys). Mean age was 16.7 ± 1.0 years and 16.8 ±1.0 years in low GI and control group respectively. 58.7% subjects completed the study at 6 months (65.4% in low GI group and 51.9% in control group). After adjustment for age and sex, subjects in the low GI group had a significantly greater reduction in obesity indices including BMI, body weight and waist circumference (WC) compared to subjects in the control group (all p <0.05). After further adjustment for physical activity levels, WC was found to be significantly lower in the low GI group compared to the conventional group (p = 0.018). Conclusion Low GI diet in the context of a comprehensive lifestyle modification program may be an alternative to conventional diet in the management of obese adolescents.

To evaluate the effects of the National Essential Medicine Policy (NEMP) on outpatient service utilization and expenditure in Tianjin, China. All government-owned general primary health care centers (PHCs) within the Urban Employee Basic Medical Insurance in Tianjin were involved in the study. Of these, 49 PHCs implemented the NEMP in April 2009, and constituted the intervention group, and the remaining PHCs constituted the control group. Patients who had visited only one of the two groups at least once pre-NEMP (April 2008 to March 2009) and post-NEMP (April 2009 to March 2010) were included in the correspondent group. A difference-in-differences (DID) analysis was used to estimate the impacts adjusting for patients' sociodemographic characteristics and health status. Sensitivity was tested using the propensity score matching method. A total of 23,362 and 4,148 patients from the intervention and control groups were identified, respectively. The patients in the intervention group were older (63.7 years vs. 58.8 years; P < 0.001) and in worse health status, as indicated by the Quan-Charlson comorbidity index (1.0 vs. 0.7; P < 0.001), than their counterparts in the control group. The DID results controlling for other confounders indicated that the annual outpatient visits, total annual expenditure, drug expenditure, and out-of-pocket expenditure per capita for the intervention group were not significantly different from those of the control group. Propensity score matching-adjusted DID regression models demonstrated similar results. The China NEMP implementation did not affect the annual outpatient visits, total expenditure, drug expenditure, and out-of-pocket expenditure in the short term and the original policy goals were not met.

Studies conducted so far on the effect of hyperthyroidism on oxidative stress (OS) have employed blood and urine samples. Exhaled Breath Condensate (EBC) is a non-invasive technique used to take sample from lungs to determine many biological indications. The aim of the present study was determine the possibility of using 8- isoprostane levels in EBC as an indicator of OS in hyperthyroid patients. The present study was performed on 42 patients with hyperthyroidism and 42 healthy control subjects. Hyperthyroid patients included patients with newly diagnosed Graves' disease, toxic multinodular goiter and toxic adenoma. Exhaled breath condensates were collected from patients in each group using a condensing device. 8- isoprostane levels as an indicator of OS in EBC were detected via immunoassay method. Hyperthyroid patients and control groups had 8-isoprostane levels of 6.08±6.31 and 1.56±0.88 pg/ml, respectively. The difference between patient and control groups was statistically significant (p<0.001). Of the hyperthyroid patients, eleven had Graves', 21 multinodular goiter, and 10 toxic adenoma diagnosis. There were no significant differences among patients of different diagnoses for 8-isoprostane levels (p=0.541). No significant correlations were found between 8-isoprostane and free thyroxine (fT4) or thyroid stimulating hormone (TSH) levels. In the present study, 8-isoprostane levels in EBC of hyperthyroid patients were found to be significantly higher than that in healthy control group. This study is important in that it is the first to evaluate the effects on respiratory system of elevated OS of hyperthyroidism in EBC.

To observe the effects of electroacupuncture (EA) with branch-foundation acupoint combination on the indices regarding pituitary-target gland axis in aging rats with yang deficiency, so as to explore its regulating mechanism on aging rats with yang deficiency. Forty healthy Sprague-Dawley female rats were randomly divided into a normal control group, a model group, an EA group and an EA control group, 10 rats in each group. Except the normal control group, the rats in the rest 3 groups were all treated with subcutaneous injection of D-galactose for 40 d, followed by intramuscular injection of hydrocortisone for 7 d to establish aging model with yang deficiency. After the successful establishment of model, the EA group was treated with EA at "Guanyuan" (CV 4), "Housanli" (ST 36) and "Baihui "(GV 20) while the EA control group was treated with EA at "Zhongji" (CV 3) "Yinlingquan" (SP 9) and "Yintang" (GV 29); the rats in the normal control group and model group were immobilized and fixed during the same time period. The treatments were given 6 times per week totally for 4 weeks. With radiation immunity analysis method, the 8 biological indices of pituitary-target gland axis, including thyroid-stimulating hormone (TSH), triiodothyronine (T3), tetraiodothyronine-4 (T4), adrenocorticotropic hormone (ACTH), corticosterone (CORT), estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were detected to observe the changes of their content. Compared with the normal control group, the serum level of TSH, T3, T4 and E2 were reduced in the model group (P<0.05, P< 0.01) while those of ACTH, CORT, FSH and LH were increased (P<0.05, P<0.01). Compared with the model group, the serum level of TSH, T3, T4 and E2 were increased in the EA group (P<0.05, P<0.01) while those of ACTH, CORT, FSH and LH were significantly reduced (P<0.05, P<0.01). Compared with the EA control group, the content of TSH was increased in the EA group without statistical significance (P>0.05), that of T3, T4 and E2 was increased (all P<0.05) and that of ACTH, CORT, FSH and LH was significantly reduced (all P<0.05). The electroacupuncture with branch-foundation acupoint combination has benign regulating effects on the key hormones of pituitary-target gland axis, which could effectively improve the dysfunction of pituitary-target gland axis that is caused by aging with yang deficiency; the efficacy of electroacupuncture with branch-foundation acupoint combination is superior to that of adjacent control acupoint combination.

Acute postoperative pain delays recovery and increases morbidity and mortality. Traditional administration of postoperative analgesics by nurses is often inefficient. The present study evaluated the safety, efficacy, and usability of a novel, patient-controlled analgesic dispenser, the PCoA Acute. A controlled pilot study was conducted at three medical centers. Patients scheduled for elective surgery were enrolled into two groups, both taking oral analgesics: a control group ( n = 43), opioids dispensed by nurses, and a test group ( n = 27), opioids dispensed via the PCoA Acute. Pill intake data were recorded. Pain ratings at rest and during movement were surveyed. No severe adverse events were recorded. Average pill intake time was reduced from 8 : 58 minutes in the control group to 1 : 17 minutes in the test group ( P value < 0.05). The test group took 67% more pills than the control group, indicating enhanced compliance. Pain scores were significantly lower for patients in the test group ( P value < 0.05). Over 90% of PCoA Acute users were satisfied with its use. The study confirmed that PCoA Acute is safe and effective. It is well accepted by patients and medical staff. Its use can optimize pain medication administration.

This study aimed to examine the effects of melatonin supplementation on liver glycogen levels in rats with streptozotocin- induced diabetes and subjected to acute swimming exercise. Eighty Sprague-Dawley type adult male rats were divided into eight groups: Group 1, general control; Group 2, melatonin-supplemented control; Group 3, melatonin-supplemented diabetes; Group 4, swimming control; Group 5, melatonin-supplemented swimming; Group 6, melatonin-supplemented diabetic swimming; Group 7, diabetic swimming; Group 8, diabetic control. Melatonin was supplemented at a dose of 3 mg/kg/day intraperitoneally for four weeks. Liver tissue samples were collected and evaluated using a Nikon Eclipse E400 light microscope. All images obtained from the light microscope were transferred to PC medium and evaluated using Clemex PE 3.5 image analysis software. The lowest liver glycogen levels in the study were found in group 4. Liver glycogen levels in groups 3, 6, 7 and 8 (the diabetic groups) were higher than group 4, but lower than those in groups 1 and 2. The lowest liver glycogen levels were obtained in groups 1 and 2. The study indicates that melatonin supplementation maintains the liver glycogen levels that decrease in acute swimming exercise, while induced diabetes prevents this maintenance effect in rats.

Monocrotaline (MCT) is a hepatotoxic pyrrolizidine alkaloid that is derived from plants; exposure may occur by consumption of contaminated grains, herbal teas and medicines. MCT can cause liver damage. We investigated the antioxidant effects of selenium (Se) and vitamin E against the toxic effects of MCT. Female Wistar albino rats were divided into four groups: a control group, an MCT group, an MCT + Se group, and an MCT + vitamin E group. Liver tissues were harvested, fixed, processed to paraffin and sections were cut. Anti-von Willebrand factor (vWF) immunohistochemistry, terminal deoxynucleotidyl transferase dUTP nick end-labeling (TUNEL), and hematoxylin and eosin staining were performed. Serum and liver tissue glutathione (GSH), catalase (CAT), and glutathione peroxidase (GPx) levels were measured. Histopathological and TUNEL data showed significantly increased liver damage in the MCT group compared to controls. Histopathological and TUNEL staining indicated significant improvements in the MCT + vitamin E and MCT + Se groups compared to the MCT group. MCT significantly reduced the serum GSH level and GPx activity, and liver GPx activity. Biochemical data indicated a significant improvement in serum GSH level in the MCT + vitamin E group compared to the MCT group. We suggest that vitamin E and Se afford limited protection against MCT hepatotoxicity.

To determine the safety of acute normovolemic hemodilution (ANH) for patients undergoing neurosurgical procedures. A group of 100 patients undergoing neurosurgical procedures was assigned prospectively to receive ANH. A group of 47 patients who underwent craniotomy for aneurysm clipping and standard anesthetic management was used as a control. Procedures conducted under ANH were performed without significant variations in physiologic parameters. Compared with controls, intraoperative blood loss, operative time, incidence and grade of complications, and length of hospital stay were similar between the two groups. Although the ANH group showed a difference in prothrombin levels before and after hemodilution procedures, the levels were still considered within physiologic parameters. Platelet counts and partial thromboplastin time (PTT) levels indicated no significant variations in either group. During the ANH procedure, a considerable reduction of brain oxygen extraction was observed in individuals with worse preoperative neurologic status (P < 0.05), indicating potential benefit. Among patients with cerebral aneurysm, patients with good initial clinical grades had better clinical results as indicated by Glasgow Outcome Scale scores (P < 0.02). ANH is a safe procedure for patients undergoing neurosurgical procedures. Further studies are necessary to confirm the improvement in brain oxygen extraction and the clinical impact. Nonetheless, patients undergoing aneurysm clipping with good clinical grades seem to profit from ANH. Copyright © 2013 Elsevier Inc. All rights reserved.

From assessment to improvement of elderly care in general practice using decision support to increase adherence to ACOVE quality indicators: study protocol for randomized control trial

PubMed Central

2014-01-01

Background Previous efforts such as Assessing Care of Vulnerable Elders (ACOVE) provide quality indicators for assessing the care of elderly patients, but thus far little has been done to leverage this knowledge to improve care for these patients. We describe a clinical decision support system to improve general practitioner (GP) adherence to ACOVE quality indicators and a protocol for investigating impact on GPs’ adherence to the rules. Design We propose two randomized controlled trials among a group of Dutch GP teams on adherence to ACOVE quality indicators. In both trials a clinical decision support system provides un-intrusive feedback appearing as a color-coded, dynamically updated, list of items needing attention. The first trial pertains to real-time automatically verifiable rules. The second trial concerns non-automatically verifiable rules (adherence cannot be established by the clinical decision support system itself, but the GPs report whether they will adhere to the rules). In both trials we will randomize teams of GPs caring for the same patients into two groups, A and B. For the automatically verifiable rules, group A GPs receive support only for a specific inter-related subset of rules, and group B GPs receive support only for the remainder of the rules. For non-automatically verifiable rules, group A GPs receive feedback framed as actions with positive consequences, and group B GPs receive feedback framed as inaction with negative consequences. GPs indicate whether they adhere to non-automatically verifiable rules. In both trials, the main outcome measure is mean adherence, automatically derived or self-reported, to the rules. Discussion We relied on active end-user involvement in selecting the rules to support, and on a model for providing feedback displayed as color-coded real-time messages concerning the patient visiting the GP at that time, without interrupting the GP’s workflow with pop-ups. While these aspects are believed to increase clinical decision support system acceptance and its impact on adherence to the selected clinical rules, systems with these properties have not yet been evaluated.

Pathak, Mauchumi Saikia; Paul, Anindita

2015-01-01

Introduction Pregnancy induced hypertension (PIH) includes Gestational hypertension, Pre-eclampsia and Eclampsia and is one of the most common obstetric complication. Worldwide about 76,000 pregnant women die each year from pre-eclampsia and related hypertensive disorders. The aetiology of Pre-eclampsia is unknown but it is thought to be related to abnormal development of placenta. Several studies have shown the presence of reduced endothelial function in pre-eclamptic pregnancy. Endothelial dysfunction is also a feature of atherosclerosis. Aim To assess fasting lipid profile and atherogenic indices in women diagnosed with pre-eclampsia as well as in women with normal pregnancy and to correlate the findings of pre-eclamptic women with that of normal pregnant women, in an attempt to utilize the data for the development of a new clinical approach for early recognition and prevention of risk of future cardiovascular diseases in women with PIH. Materials and Methods This case-control study was conducted on 50 pre-eclampsia patients who were in third trimester of pregnancy (Case group). A control group of 50 age and gestational age matched normal pregnant women was taken. Strict inclusion and exclusion criteria were followed. Fasting Lipid profile parameters were assessed and used to calculate the atherogenic indices namely Atherogenic index of plasma (AIP), Cardiac risk ratio (CRR) and Atherogenic coefficient (AC). Statistical Analysis was done by using student’s t-test. Mann-Whitney U-test was used wherever applicable and correlations between the variables were estimated by Pearson’s correlation coefficients. Results There was an extremely significant (p<0.0001) increase in Atherogenic indices (AIP, CRR and AC) in case group as compared to the control group. A positive and significant correlation of systolic blood pressure with AIP (r=0.3583), CRR (r=0.3137), AC (r=0.3193) was found in cases. There was a positive and significant correlation between gestational age and atherogenic indices in the case group. Conclusion Women with pre-eclampsia present abnormalities in lipid profile and these lipids turn out to be a risk factor for cardiovascular complications. Evaluation of the atherogenic indices during pregnancy may help prevent this risk. PMID:26393117

Poor adherence and a lack of understanding of medication instructions for oral antidiabetic use are key factors that inhibit the control of glycemic levels. The aforementioned situation needs intervention to improve medication adherence and the therapy. This study was conducted with a quasi-experimental design with prospective data collection. The subjects of this study were 50 outpatients with type 2 diabetes melitus (T2DM) who had received oral antidiabetic medicine therapy at least six months prior to adherence measurement. The patients were classified into two groups-the control group and the intervention group. The intervention group received Short Message Service (SMS) messages of diabetes education, while the control group did not. Data collection was conducted by doing interviews and administering the Morisky Medication Adherence Scale (MMAS) questionnaire. The results showed the increase in adherence in the intervention group as 1.15 ± 1.04 and that in the control group as 0.72 ± 0.90. These results indicated that there were significant differences in MMAS score between the control and intervention groups ( p < 0.05). The decrease in fasting blood glucose and glucose measured 2 h postprandially was greater in the intervention group than that in the control group. It was concluded that the provision of education through SMS had a positive effect on medication adherence and glycemic levels.

Infertility issues have been linked to the effect of oxidative reaction in the reproductive system. This study evaluated the effect of ascorbic acid, on fertility parameters of male albino Wistar rats was studied. Eighteen albino Wistar rats weighed between 178 g and 241 g were used, randomly assigned into three groups. Group 1 was the control group; oral gavaged 5 ml of distilled water; Groups 2 and 3 were administered medium dose (250 mg/kg) and high dose of ascorbic acid (400 mg/kg), respectively; twice daily for 21 days. Blood samples were obtained by cardiac puncture, and blood serum was obtained for hormonal assay, and the testes were harvested for sperm analysis. Follicle stimulating hormone levels significantly increased in the high-dose group as compared to both the control and medium dose groups. Luteinizing hormone levels in the medium dose group decreased significantly as compared to the control group. Testosterone significantly increased in both the medium- and high-dose groups as compared to the control group. Sperm motility increased significantly in the high-dose group as compared to both control and medium-dose groups. Percentage sperm concentration decreased significantly in the medium-dose group when compared to the control and increased significantly in the high-dose group as compared to the medium-dose group. For percentage normal morphology, there was a dose-dependent increase in the test groups when compared to control group. These results are indicative of a positive influence of ascorbic acid on male fertility modulators and may therefore, serve as a potential adjuvant treatment for male infertility cases.

Influence of diabetes mellitus (DM) and diabetic retinopathy (DR) on parafoveal retinal thicknesses and their ratios was evaluated. Six retinal layer boundaries were segmented from spectral-domain optical coherence tomography images using open-source software. Five study groups: (1) healthy control (HC) subjects, and subjects with (2) controlled DM, (3) uncontrolled DM, (4) controlled DR and (5) uncontrolled DR, were identified. The one-way analyses of variance (ANOVA) between adjacent study groups (i. e. 1 with 2, 2 with 3, etc) indicated differences in retinal thicknesses and ratios. Overall retinal thickness, ganglion cell layer (GCL) thickness, inner plexiform layer (IPL) thickness, and their combination (GCL+ IPL), appeared to be significantly less in the uncontrolled DM group when compared to controlled DM and controlled DR groups. Although the combination of nerve fiber layer (NFL) and GCL, and IPL thicknesses were not different, their ratio, (NFL+GCL)/IPL, was found to be significantly higher in the controlled DM group compared to the HC group. Comparisons of the controlled DR group with the controlled DM group, and with the uncontrolled DR group, do not show any differences in the layer thicknesses, though several significant ratios were obtained. Ratiometric analysis may provide more sensitive parameters for detecting changes in DR. Picture: A representative segmented OCT image of the human retina is shown. © 2017 Wiley-VCH Verlag GmbH & Co.

2013-06-01

People with chronic ankle instability display different ankle joint motions compared to healthy people. The purpose of this study was to investigate the strategies used to control ankle joint motions between a group of people with chronic ankle instability and a group of healthy, matched controls. Kinematic data were collected from 11 people with chronic ankle instability and 11 matched control subjects as they performed a single-leg land-and-cut maneuver. Three-dimensional ankle joint angles were calculated from 100 ms before, to 200 ms after landing. Kinematic control of the three rotational ankle joint degrees of freedom was investigated by simultaneously examining the three-dimensional co-variation of plantarflexion/dorsiflexion, toe-in/toe-out rotation, and inversion/eversion motions with principal component analysis. Group differences in the variance proportions of the first two principal components indicated that the angular co-variation between ankle joint motions was more linear in the control group, but more planar in the chronic ankle instability group. Frontal and transverse plane motions, in particular, contributed to the group differences in the linearity and planarity of angular co-variation. People with chronic ankle instability use a different kinematic control strategy to coordinate ankle joint motions during a single-leg landing task. Compared to the healthy group, the chronic ankle instability group's control strategy appeared to be more complex and involved joint-specific contributions that would tend to predispose this group to recurring episodes of instability.

We investigated the effect of Ginkgo biloba extract on apoptosis of brain tissues in rats with acute cerebral infarction and apoptosis-related gene expression. Rat models of acute cerebral infarction were constructed using the suture method, and randomly divided into the control group, model, and treatment groups. In the treatment group, 4 mg/kg G. biloba extract was intravenously injected into the rat tail vein. Phosphate-buffered saline solution was injected in the model group. Seventy-two hours after treatment, rats were euthanized, and brain tissues were removed to analyze the changes in caspase-3, B-cell lymphoma 2 (Bcl-2), and Bcl-2-associated X protein (Bax) mRNA and protein levels, and variation in brain tissue cells' apoptosis indices was measured. Compared with the control group, the model and treatment groups showed significantly upregulated caspase-3, Bcl-2, and Bax mRNA and protein levels in brain tissues, but remarkably downregulated Bcl-2 mRNA and protein levels (P < 0.05). After treatment, in treatment group brain tissues, caspase-3 and Bax mRNA and protein levels were significantly lower than those in the model group, while Bcl-2 mRNA and protein levels were higher than that in the model group (P < 0.05). The model and treatment groups showed increased cell apoptosis indices of brain tissues compared to the control group; after treatment, the apoptosis index in the treatment group was significantly downregulated compared with that in the model group (P < 0.05). In conclusion, G. biloba extract significantly reduced apoptosis in rat brain tissue cells with acute cerebral infarction and thus protected brain tissues.

A cluster randomised trial was conducted to evaluate the efficacy of a health promotion intervention aimed at improving knowledge and preventing sexually transmitted diseases (STD) amongst Grade 9 primary school students in Salerno (Italy). Students were randomized to either one of two groups: intervention group or control group. The intervention group was required to attend three meetings, each lasting one and a half hours. A questionnaire was then administered to both groups to evaluate knowledge of STD, contraception, sexuality, affectivity, satisfaction with interpersonal relationships with family, social groups and healthcare professionals. Variations of knowledge in the two groups were evaluated through calculation of odds ratios. Three hundred twenty-two students participated in the study. All students who received the study intervention were able to identify at least one STD post-intervention, while 2.5% of students in the control group did not indicate any. Students in the intervention group were more likely to select condoms as the most suitable contraception for young people (OR 5.54; 95% CI 3.27 -9.38), compared to controls (OR 1.91; 95% CI 1.20 - 3.05) (p = 0.002). They were also better aware of the possibility of contracting a STD even after incomplete sexual intercourse (OR 0.21, 95% CI 0.13 to 0.35), with a statistically significant difference (p <0.001) compared to the control group (OR 0.71, 95% CI 0.45 to 1.11). In addition, students in the intervention group were more likely to turn to their own parents when having doubts about sexual issues (p = 0.004) and female students to consider their gynecologist as a reference figure. In conclusion, the findings indicate that students randomized to the intervention group were more informed and aware of issues related to sexuality and its associated risks.

The purpose of this study was to evaluate the effect of cooperative learning strategies on students' attitudes toward science and achievement in BSC 1005L, a non-science majors' general biology laboratory course at an urban community college. Data were gathered on the participants' attitudes toward science and cognitive biology level pre and post treatment in BSC 1005L. Elements of the Learning Together model developed by Johnson and Johnson and the Student Team-Achievement Divisions model created by Slavin were incorporated into the experimental sections of BSC 1005L. Four sections of BSC 1005L participated in this study. Participants were enrolled in the 1998 spring (January) term. Students met weekly in a two hour laboratory session. The treatment was administered to the experimental group over a ten week period. A quasi-experimental pretest-posttest control group design was used. Students in the cooperative learning group (nsb1 = 27) were administered the Test of Science-Related Attitudes (TOSRA) and the cognitive biology test at the same time as the control group (nsb2 = 19) (at the beginning and end of the term). Statistical analyses confirmed that both groups were equivalent regarding ethnicity, gender, college grade point average and number of absences. Independent sample t-tests performed on pretest mean scores indicated no significant differences in the TOSRA scale two or biology knowledge between the cooperative learning group and the control group. The scores of TOSRA scales: one, three, four, five, six, and seven were significantly lower in the cooperative learning group. Independent sample t-tests of the mean score differences did not show any significant differences in posttest attitudes toward science or biology knowledge between the two groups. Paired t-tests did not indicate any significant differences on the TOSRA or biology knowledge within the cooperative learning group. Paired t-tests did show significant differences within the control group on TOSRA scale two and biology knowledge. ANCOVAs did not indicate any significant differences on the post mean scores of the TOSRA or biology knowledge adjusted by differences in the pretest mean scores. Analysis of the research data did not show any significant correlation between attitudes toward science and biology knowledge.

Generalized Anxiety Disorder (GAD) is a high prevalence, chronic disorder. Web-based interventions are acceptable, engaging, and can be delivered at scale. Few randomized controlled trials evaluate the effectiveness of prevention programs for anxiety, or the factors that improve effectiveness and engagement. The intent of the study was to evaluate the effectiveness of a Web-based program in preventing GAD symptoms in young adults, and to determine the role of telephone and email reminders. A 5-arm randomized controlled trial with 558 Internet users in the community, recruited via the Australian Electoral Roll, was conducted with 6- and 12-month follow-up. Five interventions were offered over a 10-week period. Group 1 (Active website) received a combined intervention of psycho-education, Internet-delivered Cognitive Behavioral Therapy (ICBT) for anxiety, physical activity promotion, and relaxation. Group 2 (Active website with telephone) received the identical Web program plus weekly telephone reminder calls. Group 3 (Active website with email) received the identical Web program plus weekly email reminders. Group 4 (Control) received a placebo website. Group 5 (Control with telephone) received the placebo website plus telephone calls. Main outcome measures were severity of anxiety symptoms as measured by the GAD 7-item scale (GAD-7) (at post-test, 6, and 12 months). Secondary measures were GAD caseness, measured by the Mini International Neuropsychiatric Interview (MINI) at 6 months, Centre for Epidemiologic Studies-Depression scale (CES-D), Anxiety Sensitivity Index (ASI), Penn State Worry Questionnaire (PSWQ), and Days out of Role. GAD-7 symptoms reduced over post-test, 6-month, and 12-month follow-up. There were no significant differences between Group 4 (Control) and Groups 1 (Active website), 2 (Active website with telephone), 3 (Active website with email), or 5 (Control with telephone) at any follow-up. A total of 16 cases of GAD were identified at 6 months, comprising 6.7% (11/165) from the Active groups (1, 2, 3) and 4.5% (5/110) from the Control groups (4, 5), a difference that was not significant. CES-D, ASI, and PSWQ scores were significantly lower for the active website with email reminders at post-test, relative to the control website condition. Indicated prevention of GAD was not effective in reducing anxiety levels, measured by GAD-7. There were significant secondary effects for anxiety sensitivity, worry, and depression. Challenges for indicated prevention trials are discussed.

This study investigated the effects of skim milk on the quality and fertility of boar spermatozoa under long-term chilled preservation. Semen samples were stored in Modena solution supplemented with 0 (control) to 50 mg/mL skim milk at 5°C for 4 weeks; spermatozoa stored with 7.5 and 15 mg/mL of skim milk (7.5-SM and 15-SM groups, respectively) exhibited significantly higher motility indices than those of the control group up to 3 weeks (P < 0.05), and the 7.5-SM group showed improved motility indices even after 4 weeks (P < 0.05). In vitro fertilization using spermatozoa in the 7.5-SM and 15-SM groups stored at 5°C for 2 weeks showed significantly higher fertilization rates of spermatozoa and the development rates to blastocyst than the control group (P < 0.05), and the 7.5-SM group showed similar rates of fertilization and blastocyst formation in the fresh non-stored spermatozoa group. After artificial insemination using spermatozoa stored for 2 weeks in the 7.5-SM group, healthy piglets were obtained. Boar spermatozoa can be stored at 5°C in a Modena solution containing skim milk. Supplementation of 7.5 mg/mL skim milk improves boar spermatozoa motility and fertility even after liquid preservation at 5°C for 2 weeks. © 2013 Japanese Society of Animal Science.

DSM-IV-TR “pain disorder associated with psychological factors” as a nonhysterical form of somatization

2008-01-01

BACKGROUND: Elevated Minnesota Multiphasic Personality Inventory (MMPI) scores on the hysteria (Hy) scale are reported in several forms of pain. Previous results were possibly biased by diagnostic heterogeneity (psychogenic, somatic and mixed pain syndromes included in the same index sample) or Hy heterogeneity (failure to differentiate Hy scores into clinically meaningful sub-scales, such as admission of symptoms [Ad] and denial of symptoms [Dn]). METHODS: To overcome this drawback, 48 patients diagnosed as having a Diagnostic and Statistical Manual of Mental Disorders, 4th edn, Text Revision (DSM-IV-TR) diagnosis of “pain disorder associated with psychological factors” were compared with 48 patients experiencing somatic pain excluding psychological factors, and 42 somatic controls without pain. RESULTS: MMPI Hy and hypochondriasis (Hs) scores were significantly higher in the pain disorder group than in control groups, who scored similarly. MMPI correction (K) scores and Dn scores were similar in the three groups, whereas Ad was significantly higher in the pain disorder group and lower and similar in the two control groups, respectively. In the pain disorder group, Ad and Dn were negatively correlated, whereas in control groups they were unrelated. CONCLUSIONS: These findings suggest that whereas a pattern of high Hs and Hy scores together with a normal K score might characterize patients with a pain disorder associated with psychological factors, elevated Hy scores per se do not indicate hysterical traits. In the pain disorder group, elevated Hy scores reflected the Ad subscale alone, indicating a strikingly high frequency of distressing somatic symptoms. They tend not to repress or deny the emotional malaise linked to symptoms, as the hysterical construct expects. The pain disorder designation should be considered a nonhysterical form of somatization. PMID:18301811

Apart from increased temperature, thermal effluents discharged through cooling systems of nuclear power plants may often contain chlorine (used against bio-fouling), which may affect the immune status of fish. Therefore, a 28-day trial was undertaken to delineate the effect of high temperature and a persistent sub-lethal chlorine exposure on immunomodulation in Cyprinus carpio advanced fingerlings. Fish were acclimated to four different temperatures (26, 31, 33 and 36 degrees C) and maintained for 30 days in two different groups. One group was exposed to persistent chlorine (0.1mgL(-1)) and was compared with their respective temperature control groups (without chlorine exposure). Expression of heat shock proteins (hsp 70) was tested in muscle after 28 days using Western blotting. Haematological parameters (erythrocyte count, leucocyte count, haemoglobin), serum parameters (total protein, albumin, globulin, A/G ratio) and respiratory burst activity were tested to assess immuno-competence of C. carpio in response to temperature and chlorine exposure. Results indicated that hsp 70 was induced at 36 degrees C in temperature control groups but not in their respective temperatures in the presence of chlorine. Haematological parameters such as haemoglobin, erythrocyte and leucocyte counts appeared depressed in chlorine treated groups as compared to their respective temperature control groups. Serum protein and globulin were affected due to chlorine exposure at different acclimation temperatures. A decrease in NBT activity was recorded in chlorine treated groups as compared to their respective temperature control groups. Overall results indicate that increasing acclimation temperatures alters the immune status of C. carpio advanced fingerlings and persistent sub-lethal exposure to chlorine augments this temperature induced immunosuppression.

Prehypertension is one of the cardiovascular disease predicators. Management of prehypertension is an appropriate objective for clinicians in a wide range of medical centers. Massage therapy is primarily nonpharmacological treatment that is used to control blood pressure (BP). This study intends to investigate the long-term effect of massage therapy on BP in prehypertensive women. This was a single-blind clinical trial study conducted on 50 prehypertensive women who referred to Sedigheh Tahereh Cardiovascular Center, during 6 months in 2009. Participants were selected by simple random sampling and were divided into control and intervention groups. The test group (25 patients) received massage for 10-15 min, three times a week for 10 sessions, and the control group (25 patients) was relaxed in the same environment but with no massage. Their BP was measured before and after each session and 72 h and 2 weeks after finishing the massage therapy. Analyzing the data was done using descriptive and inferential statistical methods (Chi-square, Mann-Whitney, paired t -test, and Student's t -test) through SPSS software version 18 and a significant level was considered as P < 0.05. The results indicated that the mean systolic BP (SBP) and diastolic BP (DBP) in the massage group were significantly lower in comparison with the control group ( P < 0.001). Evaluation of durability of the massage effects on BP also indicated that 72 h after finishing the study, still there was a significant difference between the test and control groups in SBP and DBP ( P < 0.001), but after 2 weeks, there was not a significant difference in SBP and DBP ( P > 0.05) between the two groups. Although massage therapy seems to be a safe, effective, applicable, and cost-effective intervention to control BP of prehypertensive women, its effects do not persist for a long time.

Research indicates that exercise can have a positive effect on both physical and mental health in nursing home patients with dementia, however the lasting effect is rarely studied. In a previously published article we investigated the immediate effect of a 12 weeks functional exercise program on physical function and mental health in nursing home residents with dementia. In this paper we studied the long-term effect of this exercise program. We explored the differences between the exercise and control group from baseline to 6 months follow-up and during the detraining period from month 3 to 6. A single blind, randomized controlled trial was conducted and a total of 170 nursing home residents with dementia were included. The participants were randomly allocated to an intervention (n = 87) or a control group (n = 83). The intervention consisted of intensive strengthening and balance exercises in small groups twice a week for 12 weeks. The control condition was leisure activities. Thirty participants were lost between baseline and six-month follow-up. Linear mixed model analyses for repeated measurements were used to investigate the effect of exercise after detraining period. The exercise group improved their scores on Berg Balance Scale from baseline to 6 months follow-up by 2.7 points in average. The control group deteriorated in the same period and the difference between groups was statistically significant (p = 0.031). The exercise group also scored better on NPI agitation sub-score after 6 months (p = 0.045). The results demonstrate long-time positive effects of a high intensity functional exercise program on balance and indicate a positive effect on agitation, after an intervention period of 12 weeks followed by a detraining period of 12 weeks.

2017-01-01

Purpose Although it is frequently presumed that bulbar muscle degeneration in Amyotrophic Lateral Sclerosis (ALS) is associated with progressive loss of speech motor control, empirical evidence is limited. Furthermore, because speaking rate slows with disease progression and rate manipulations are used to improve intelligibility in ALS, this study sought to (i) determine between and within-group differences in articulatory motor control as a result of speaking rate changes and (ii) identify the strength of association between articulatory motor control and speech impairment severity. Method Ten talkers with ALS and 11 healthy controls repeated the target sentence at habitual, fast, and slow rates. The spatiotemporal variability index (STI) was calculated to determine tongue, lower lip, and jaw movement variability. Results During habitual speech, talkers with mild-moderate dysarthria displayed significantly lower tongue and lip movement variability whereas those with severe dysarthria showed greater variability compared to controls. Within-group rate effects were significant only for talkers with ALS. Specifically, lip and tongue movement variability significantly increased during slow speech relative to habitual and fast speech. Finally, preliminary associations between speech impairment severity and movement variability were moderate to strong in talkers with ALS. Conclusion Between-group differences for habitual speech and within-group effects for slow speech replicated previous findings for lower lip and jaw movements. Preliminary findings of moderate to strong associations between speech impairment severity and STI suggest that articulatory variability may vary from pathologically low (possibly indicating articulatory compensation) to pathologically high variability (possibly indicating loss of control) with dysarthria progression in ALS.

To assess the effects of yogic exercise on nonspecific neck pain in university students. This study is a pretest-posttest design with a non-equivalent control group. Thirty-eight university students were selected by convenience sampling, with 18 assigned to an exercise group and 20 assigned to a control group. The yoga group participated in one-hour sessions of yogic exercise two days a week for eight weeks. The exercise comprised eight stages: relaxation, flexion of neck, extension of neck, right lateral flexion of neck, left lateral flexion of neck, right rotation of neck, left rotation of neck, and relaxation. Neck pain intensity was measured using a 100 mm visual analogue scale. The yoga group showed significantly decreased neck pain scores compared with those of the control group. These findings indicate that yogic exercises could reduce neck pain in university students. Copyright © 2017 Elsevier Ltd. All rights reserved.

This study aimed to compare the effects of relaxation techniques on fatigue in hemodialysis patients. This clinical trial study was conducted on 105 hemodialysis patients. The subjects were categorized into three groups as: relaxation, aromatherapy and control. In the relaxation group, Benson muscle relaxation techniques were employed; in the aromatherapy group, the inhalation of two drops of 5% lavender essential oil used and the control group only received regular healthcare actions. Data collected by using brief fatigue inventory, before and after the intervention. Results of the current study indicated significant differences in the mean of changes in fatigue scores before and after the intervention between the relaxation and aromatherapy groups, but the difference was insignificant in the control group. Aromatherapy with lavender essential oil can decrease the level of fatigue in the patients undergoing hemodialysis compared to Benson relaxation techniques. Copyright © 2018 Elsevier Ltd.

1. Antioxidant and methyl donor effects of betaine in experimental animal models have recently been demonstrated. The present study was therefore designed to examine the antioxidant effects of betaine on the antioxidant status and meat quality of breast muscles in broilers. 2. Cobb broilers were randomly divided into Control, Methionine low, Methionine low plus betaine, and Betaine groups. 3. The activity of the main antioxidant enzyme (glutathione peroxidase) in the Betaine and the Methionine low plus betaine groups significantly increased compared to the Methionine low and Control groups. Catalase and superoxide dismutase activities were significantly higher in the Betaine group compared to the Methionine low group, and lipid peroxidation was significantly higher in the Control and the Methionine low groups. 4. The present study indicates that adding betaine (1 g/kg) to a diet deficient in methionine can significantly improve antioxidant defences and meat quality, decreasing lipid peroxidation in the breast muscles of broiler chickens.

The current study examined the effects of aromatherapy massage on alleviating agitation and depressive mood in individuals with dementia. A randomized controlled trial and repeated measures design was conducted. A total of 59 participants were randomly assigned to intervention or control groups. The intervention group received aromatherapy massage once per week for 8 weeks. Results indicated no significant changes over time in overall agitation for either group, but agitation decreased from Week 1 to Week 5 for the intervention group. In addition, the overall depressive symptoms decreased significantly over time for the intervention group compared to the control group (p < 0.001). However, changes in agitation within 24 hours following aromatherapy massage showed some significant changes in Weeks 5 and 9. Aromatherapy massage can be an effective and safe intervention to alleviate specific agitated behaviors and depressive mood in individuals with dementia.

Neuropsychological functioning was examined in a group of 33 older (mean age 62.40 +/- 9.62 years) people with Type 2 diabetes (Group 1) and 33 non-diabetic participants matched with Group 1 on age, sex, premorbid intelligence and presence of hypertension and cardio/cerebrovascular conditions (Group 2). Data statistically corrected for confounding factors obtained from the diabetic group were compared with the matched control group. The results suggested small cognitive deficits in diabetic people's verbal memory and mental flexibility (Logical Memory A and SS7). No differences were seen between the two samples in simple and complex visuomotor attention, sustained complex visual attention, attention efficiency, mental double tracking, implicit memory, and self-reported memory problems. These findings indicate minimal cognitive impairment in relatively uncomplicated Type 2 diabetes and demonstrate the importance of control and matching for confounding factors.

We investigated the effect of cellooligosaccharide (CE) or a combination of dextran and Lactobacillus casei ssp. casei strain JCM1134(T) (synbiotic; SB) feeding on growth performance, fecal condition and hormone concentrations in Holstein calves. Fifty-two female Holstein calves were randomly assigned to three treatment groups: CE feeding group (n = 16), SB feeding group (n = 18), and control group (n = 18). Body weight at 90 days of age, as well as daily body weight gain (DG) and feed efficiency after weaning to 90 days of age were greater (P < 0.05) in the CE feeding group than in the control group. The total fecal score tended to be lower (P < 0.1) in the SB feeding group than in the control group. Plasma insulin concentration was higher (P < 0.05) in the CE feeding group than in the control group at 90 days of age. Our results indicate that CE feeding improved DG and feed efficiency in calves. On the other hand, there was less effect on growth performance and fecal Escherichia coli counts in calves fed SB. 2011 The Authors. Animal Science Journal © 2011 Japanese Society of Animal Science.

Causes of placebo effects in antidepressant trials have been inferred from observational studies and meta-analyses, but their mechanisms have not been directly established. The goal of this study was to examine in a prospective, randomized controlled trial whether patient expectancy mediates placebo effects in antidepressant studies. Adult outpatients with major depressive disorder were randomly assigned to open or placebo-controlled citalopram treatment. Following measurement of pre- and postrandomization expectancy, participants were treated with citalopram or placebo for 8 weeks. Independent samples t tests determined whether patient expectancy differed between the open and placebo-controlled groups, and mixed-effects models assessed group effects on Hamilton Depression Rating Scale (HAM-D) scores over time while controlling for treatment assignment. Finally, mediation analyses tested whether between-group differences in patient expectancy mediated the group effect on HAM-D scores. Postrandomization expectancy scores were significantly higher in the open group (mean=12.1 [SD=2.1]) compared with the placebo-controlled group (mean=11.0 [SD=2.0]). Mixed-effects modeling revealed a significant week-by-group interaction, indicating that HAM-D scores for citalopram-treated participants declined at a faster rate in the open group compared with the placebo-controlled group. Patient expectations postrandomization partially mediated group effects on week 8 HAM-D. Patient expectancy is a significant mediator of placebo effects in antidepressant trials. Expectancy-related interventions should be investigated as a means of controlling placebo responses in antidepressant clinical trials and improving patient outcome in clinical treatment.

Christians) and a "control" group (with no mental disorder and non-religious). The sample consisted of individuals of both sexes. The patient sample was recruited in two psychiatric hospitals of Buenos Aires City, the religious from an evangelical cult, and people with no religious beliefs or previous psychiatric symptoms (control group). The Hallucinatory Experiences Questionnaire and the Oxford-Liverpool Inventory Feelings and Experiences were the measurement tools used. The White Christmas Test was also administered in order to assess the degree of vivid imagery hearing based on a version of signal detection paradigm in which the subjects think that they hear a song in the background of white noise. The results showed that patients showed greater attributional bias (compared with evangelicals and the control group), but the religious group also tended to show greater bias (although less) than the control group. In addition, patients tended to show greater schizotypal and hallucinatory experiences compared with the evangelicals and the control group, but surprisingly, the control group showed higher negative schizotypy than the religious group, which indicates that religious practices could help reduce the negative effects of schizotypy.

In the present study, we investigated how the electrical activity in the sensorimotor cortex contributes to improved cognitive processing capabilities and how SMR (sensorimotor rhythm, 12-15Hz) neurofeedback training modulates it. Previous evidence indicates that higher levels of SMR activity reduce sensorimotor interference and thereby promote cognitive processing. Participants were randomly assigned to two groups, one experimental (N=10) group receiving SMR neurofeedback training, in which they learned to voluntarily increase SMR, and one control group (N=10) receiving sham feedback. Multiple cognitive functions and electrophysiological correlates of cognitive processing were assessed before and after 10 neurofeedback training sessions. The experimental group but not the control group showed linear increases in SMR power over training runs, which was associated with behavioural improvements in memory and attentional performance. Additionally, increasing SMR led to a more salient stimulus processing as indicated by increased N1 and P3 event-related potential amplitudes after the training as compared to the pre-test. Finally, functional brain connectivity between motor areas and visual processing areas was reduced after SMR training indicating reduced sensorimotor interference. These results indicate that SMR neurofeedback improves stimulus processing capabilities and consequently leads to improvements in cognitive performance. The present findings contribute to a better understanding of the mechanisms underlying SMR neurofeedback training and cognitive processing and implicate that SMR neurofeedback might be an effective cognitive training tool.

Differential effect of Pistacia vera extracts on experimental atherosclerosis in the rabbit animal model: an experimental study

PubMed Central

2010-01-01

Background Lipid-enriched diets and oxidative stress are risk factors for the development of atherosclerosis. The effects of the methanolic (ME) and cyclohexane (CHE) extracts of the Pistacia vera nut, often included in the Mediterranean diet, were studied in the rabbit model of atherosclerosis. Methods and results Twenty-four New Zealand White rabbits received atherogenic diet (Control Group), supplemented with ME (Group ME) or CHE (Group CHE) for 3 months. Previously, a GC-MS and a UHPLC LC-DAD-ESI(-)-HRMS/MS method were developed to investigate the extracts' chemical profiles. Blood samples at baseline and monthly determined lipid profile, lipid peroxidation and liver function. The aorta, myocardium and liver were examined histologically at 3 months. Groups ME and CHE had significantly higher HDL- and non-significantly lower LDL-cholesterol median % changes from baseline than the Control Group. Triacylglycerol was significantly higher in Group CHE vs. Control. MDA values were significantly lower in Group ME vs. Control and CHE. ALT and AST were significantly higher in Group CHE vs. Control. γ-GT was lower in Group ME vs. Control. Aortic intimal thickness was significantly less in Groups ME and CHE vs. Control; Group ME atherosclerotic lesions were significantly less extensive vs. Groups Control and CHE. Only Group CHE had significant liver fatty infiltration. Conclusions During short-term administration concomitantly with atherogenic diet, both P. vera extracts were beneficial on HDL-, LDL-cholesterol and aortic intimal thickness. The ME additionally presented an antioxidant effect and significant decrease of aortic surface lesions. These results indicate that P. vera dietary inclusion, in particular its ME, is potentially beneficial in atherosclerosis management. PMID:20633299

The purpose of this investigation was to examine the effectiveness of intermittent lower limb occlusion in augmenting recovery from exercise induced muscle damage (EIMD) in physically active males. Randomized controlled trial, double blind. Sixteen healthy recreationally active male participants were randomly assigned to an intermittent occlusion (OCC; n=8) or control (SHAM; n=8) group. The EIMD protocol comprised of 100 drop-jumps, from a 0.6m box. Indices of muscle damage were creatine kinase (CK), thigh-circumference (TC), muscle soreness (DOMS), counter-movement jump (CMJ) and maximal isometric voluntary contraction (MIVC). Measurements were assessed pre, 24h, 48h and 72h following exercise. There was a significant time effect for all indices of muscle damage suggesting EIMD was present following the exercise protocol. The decrease in MIVC was significantly attenuated in the OCC group compared to the SHAM group at 24 (90.4±10.7 vs. 81.5±6.7%), 48 (96.2±6.1 vs. 84.5±7.1%) and 72h (101.1±4.2 vs. 89.7±7.5%). The CK response was reduced in the OCC group at 24 (335±87 vs. 636±300 IU) and 48h (244±70 vs. 393±248 IU), compared to the SHAM group. DOMS was significantly lower in the OCC compared to the SHAM group at 24, 48 and 72h post EIMD. There was no effect of OCC on CMJ or TC. This investigation shows that intermittent lower limb occlusion administered after a damaging bout of exercise reduces indices of muscle damage and accelerates the recovery in physically active males.

Observational studies and nonrandomized trials support an association between periodontal disease and atherosclerotic vascular disease. Both diseases occur frequently in Aboriginal Australians. We hypothesized that nonsurgical periodontal therapy would improve measures of arterial function and structure that are subclinical indicators of atherosclerotic vascular disease. This parallel-group, randomized, open label clinical trial enrolled 273 Aboriginal Australians aged ≥18 years with periodontitis. Intervention participants received full-mouth periodontal scaling during a single visit, whereas controls received no treatment. Prespecified primary end points measured 12-month change in carotid intima-media thickness, an indicator of arterial structure, and 3- and 12-month change in pulse wave velocity, an indicator of arterial function. ANCOVA used complete case data to evaluate treatment group differences. End points could be calculated for 169 participants with follow-up data at 3 months and 168 participants at 12 months. Intima-media thickness decreased significantly after 12 months in the intervention group (mean reduction=-0.023 [95% confidence interval {CI}, -0.038 to -0.008] mm) but not in the control group (mean increase=0.002 [95% CI, -0.017 to 0.022] mm). The difference in intima-media thickness change between treatment groups was statistically significant (-0.026 [95% CI, -0.048 to -0.003] mm; P=0.03). In contrast, there were no significant differences between treatment groups in pulse wave velocity at 3 months (mean difference, 0.06 [95% CI, -0.17 to 0.29] m/s; P=0.594) or 12 months (mean difference, 0.21 [95% CI, -0.01 to 0.43] m/s; P=0.062). Periodontal therapy reduced subclinical arterial thickness but not function in Aboriginal Australians with periodontal disease, suggesting periodontal disease and atherosclerosis are significantly associated. © 2014 American Heart Association, Inc.

The purpose of this study is to examine the influence of health news content on the stigma of suicide. In particular, this study tested whether the onset controllability and group categorization had a causal effect on people's stigma toward suicide. The results indicated that stigma scores were lower for those who read an article explaining the causes of suicide as uncontrollable than for those who read an article explaining the causes as controllable. Also, lower stigma scores were observed for those who read an article depicting suicidal people as the in-group compared to those who read an article depicting suicidal people as the out-group. Furthermore, stigma scores were the highest for those exposed to an article with the out-group categorization combined with the controllable causes of suicide.

In reflex and volitional actions, co-activations of agonist and antagonist muscles are believed to be present. Recent studies indicate that such co-activations can be either synergic or dyssynergic. The aim of this paper is to investigate if the co-activations of biceps brachii, brachialis, and triceps brachii during volitional elbow flexion are in the synergic or dyssynergic state. In this study, two groups with each containing six healthy male volunteers participated. Each person of the first group performed 30 trials of volitional elbow flexion while each of the second group performed 30 trials of passive elbow flexion as control experiments. Based on the model of fractional Brownian motion, the intensity and frequency information of the surface electromyograms (EMGs) could be extracted simultaneously. No statistically significant changes were found in the control group. As to the other group, results indicated that the surface EMGs of all five muscle groups were temporally synchronized in frequencies with persistent intensities during each elbow flexion. In addition, the mean values of fractal dimensions for rest and volitional flexion states revealed significant differences with P < 0.01. The obtained positive results suggest that these muscle groups work together synergically to facilitate elbow flexion during the co-activations.

What are the metabolic characteristics of homocysteine in polycystic ovary syndrome (PCOS)? Homocysteine concentrations were determined in serum samples from non-obese and obese control subjects and PCOS patients. Homocysteine metabolism was studied in a rat model of PCOS established using dehydroepiandrosterone (DHEA) or DHEA in combination with a high-fat diet (HFD). It was shown that (i) serum homocysteine concentrations were greater in PCOS patients than in control subjects in the obese group (P < 0.05) and serum homocysteine concentrations were significantly higher in the obese group than in the non-obese group, regardless of PCOS status (both P < 0.05); (ii) serum homocysteine concentrations were significantly increased in DHEA + HFD-induced rats compared with controls (P < 0.05); (iii) when compared with the control group, mRNA concentrations of homocysteine metabolic enzymes Bhmt and Cbs were significantly reduced in the liver tissues of DHEA + HFD-induced rats (both P < 0.0001); (iv) when compared with the control group, there was a significant decrease in the methylation concentrations of the Cbs (P < 0.05) and Bhmt (P < 0.05 and P < 0.0001) promoter in the DHEA + HFD group. The methylation patterns, together with previous data, indicate that hypomethylated promoter-mediated transcriptional activation of Bhmt and Cbs might be a defence mechanism against PCOS-related hyperhomocysteinemia. These findings indicate that decreased liver Bhmt and Cbs-mediated homocysteine metabolism might have a role in hyperhomocysteinemia in PCOS and provides further evidence for a potential role of decreased liver function in PCOS.

Canagliflozin (CAN) is a sodium-glucose co-transporter 2 (SGLT2) inhibitor indicated to improve glycemic control in adults with type 2 diabetes mellitus. There is a little information about its effect on the cholinergic system that proposed mechanism for memory improvement occurring by SGLT2 drugs. This study aimed to estimate the effect of CAN as compared to galantamine (GAL) treatments for two weeks on scopolamine hydrobromide (SCO)-induced memory dysfunction in experimental rats. Animals divided into six groups; control (CON), CAN, GAL, SCO, SCO + CAN and SCO + GAL. Results indicated significant decrease in body weights of the CAN groups as compared to control values. Moreover, in the SCO + CAN and SCO + GAL the number of arm entry and number of correct alternation in Y maze task increased and showed improvement in the water maze task, acetylcholinesterase (AChE) activities decreased significantly, while monoamines levels significantly increased compared with the SCO group values. Results also recorded acetylcholine M1 receptor (M1 mAChR) in SCO + CAN or SCO + GAL groups in comparison with the SCO group. The study suggested that canagliflozin might improve memory dysfunction induced by scopolamine hydrobromide via cholinergic and monoamines system. Copyright © 2017 Elsevier B.V. All rights reserved.

Pilot experiments were carried out to reduce the fluorine (F) and arsenic (As) pollution of roasted corn dried by open ovens in "coal-burning" fluorosis area Yunnan, China. The results indicated that the average emission amount of F and As in briquettes in experimental group were 29.20mg/kg and 0.76 mg/kg in Xiaolongdong, and 46.8 mg/kg and 0.54 mg/kg in Mangbu respectively. The results also indicated that the fixing rate of F and As in briquettes in experimental group was more than 4 times and 1.2 times of that in control group respectively. The average concentration of F and As in roasted corn in experimental group were 3.86 mg/kg and 13.23 μg/kg in Xiaolongdong, and 4.77 mg/kg and 122.96 μg/kg in Mangbu respectively, which reduced by more than 65% and 75% respectively compared with that in control group. Adding local natural calcium-based materials in briquettes can reduce the emission of F and As and their pollution on roasted corn largely, and thus will reduce the risk of fluorosis for residents greatly in "coal-burning" fluorosis area of southwestern China.

While the functional correlates of spelling impairment have been rarely investigated, to our knowledge no study exists regarding the structural characteristics of spelling impairment and potential changes with interventions. Using diffusion tensor imaging at 3.0 T, we here therefore sought to investigate (a) differences between children with poor spelling abilities (training group and waiting group) and controls, and (b) the effects of a morpheme- based spelling intervention in children with poor spelling abilities on DTI parameters. A baseline comparison of white matter indices revealed significant differences between controls and spelling-impaired children, mainly located in the right hemisphere (superior corona radiata (SCR), posterior limb of internal capsule, superior longitudinal fasciculus). After 5 weeks of training, spelling ability improved in the training group, along with increases in fractional anisotropy and decreases of radial diffusivity in the right hemisphere compared to controls. In addition, significantly higher decreases of mean diffusivity in the right SCR for the spelling-impaired training group compared to the waiting group were observed. Our results suggest that spelling impairment is associated with differences in white-matter integrity in the right hemisphere. We also provide first indications that white matter changes occur during successful training, but this needs to be more specifically addressed in future research. PMID:22198594

Abstract Objective To determine whether periodic supportive supervision after a training course improved the quality of paediatric hospital care in Kyrgyzstan, where inappropriate care was common but in-hospital postnatal mortality was low. Methods In a cluster, randomized, parallel-group trial, 10 public hospitals were allocated to a 4-day World Health Organization (WHO) course on hospital care for children followed by periodic supportive supervision by paediatricians for 1 year, while 10 hospitals had no intervention. We assessed prospectively 10 key indicators of inappropriate paediatric case management, as indicated by WHO guidelines. The primary indicator was the combination of the three indicators: unnecessary hospitalization, increased iatrogenic risk and unnecessary painful procedures. An independent team evaluated the overall quality of care. Findings We prospectively reviewed the medical records of 4626 hospitalized children aged 2 to 60 months. In the intervention hospitals, the mean proportion of the primary indicator decreased from 46.9% (95% confidence interval, CI: 24.2 to 68.9) at baseline to 6.8% (95% CI: 1.1 to 12.1) at 1 year, but was unchanged in the control group (45.5%, 95% CI: 25.2 to 67.9, to 64.7%, 95% CI: 43.3 to 86.1). At 1 year, the risk ratio for the primary indicator in the intervention versus the control group was 0.09 (95% CI: 0.06 to 0.13). The proportions of the other nine indicators also decreased in the intervention group (P < 0.0001 for all). Overall quality of care improved significantly in intervention hospitals. Conclusion Periodic supportive supervision for 1 year after a training course improved both adherence to WHO guidelines on hospital care for children and the overall quality of paediatric care.

To explore the diagnostic performance of 25-hydroxyvitamin D (25(OH)D), parathyroid hormone (PTH), bone alkaline phosphatase (BALP), and osteocalcin (OC) in predicting stroke.  Methods: This retrospective survey was conducted in The Second Affiliated Hospital to Nanchang University, Nanchang, Jiangxi Province, China. involved 121 cerebral infarction patients and 103 cerebral hemorrhage patients as the experimental groups, 100 volunteers as the healthy control group and 80 brain trauma patients as the disease control group. The 25(OH)D, PTH, BALP, and OC levels of all participants were measured by electrochemiluminescence immunoassay.  Results: The serum concentration of 25(OH)D in stroke patients was appreciably lower than that of the control groups (p less than 0.05), and subsequently, the deficiency level of 25(OH)D in the stroke population was considerably higher than that of the control groups (p less than 0.05). The serum concentrations of PTH and OC in stroke patients exceeded those found in the control groups (p less than 0.05), and the abnormal level in the stroke patients was also higher than that of the control. Compared with the control group, BALP concentrations in cerebral infarction patients were increased significantly. Additionally, abnormal levels of BALP in stroke patients were found to be higher than those in the control groups. However, concentrations and abnormal levels of BALP in cerebral hemorrhage patients were not found to be significantly different than those found in cerebral infarction and the control groups, There were no substantial differences between the 2 control groups. Conclusion: Lack of 25(OH)D and excessive PTH, BALP, and OC could indicate a high risk of stroke.

Longitudinal analysis of time, engagement, and achievement in at-risk versus non-risk students.

This longitudinal study investigated the effects of time spent in academic instruction and time engaged on elementary students' academic achievement gains. Three groups were compared over grades as follows: (a) an at-risk experimental group of low-socioeconomic status (SES) students for whom teachers implemented classwide peer tutoring (CWPT) beginning with the second semester of first grade continuing through Grade 3; (b) an equivalent at-risk control group; and (c) a non-risk comparison group of students of average- to high-SES. In both the control and comparison groups, teachers employed conventional instructional practices over Grades 1 through 3. Results indicated significant group differences in the time spent in academic instruction, engagement, and gains on the subtests of the Metropolitan Achievement Test that favored the experimental and comparison groups over the control group. Implications include the effectiveness of CWPT for at-risk students and the continuing vulnerability of at-risk students whose daily instructional programs provide less instructional time and foster lower levels of active academic engagement.

We aimed to identify the signals that indicate the possible benefits of administering Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) at the initiation of meal, compared to immediately after food. This was a randomized, controlled, pilot study in 160 patients who received only NSAIDs for various pain conditions. Patients were randomized to Group I (control group) -NSAID After Food (AF), Group II-NSAID Before Food (BF), Group III-NSAID BF for 2 days and then crossed over to AF for next two days (CO-1) and Group IV-NSAID AF for 2 days and then crossed over to BF for next two days (C0-2 group). Group III & Group IV were given a washout period of 48 hours after the initial two days of treatment. All were followed up for the next 2 drug free days. Patients were observed for the development of gastritis (epigastric distress, epigastric pain, nausea, fullness of stomach, repeated reflux) throughout the study. Symptoms of gastritis were seen in 6.45% (2/31) and 36.11% (13/36) patients in group I and II, respectively. There was no statistically significant difference in the development of gastritis in AF group. However, statistically significant difference (P<0.05) was found between BF group and AF intake of NSAIDs [CO-1 (AF), CO-2 (A.F), AF (control group)] in terms of development of gastritis. Administering NSAIDs at the initiation of meal is better tolerated as indicated by the lower incidence of gastritis. If proved in larger population, routine concurrent administration of medication for prevention of gastritis can be avoided.

The aim of this in vitro study was to evaluate the suitability of using chitosan, poly (lactide-co-glycolide) (PLGA), and polymethyl methacrylate (PMMA) to control the release of chlorhexidine digluconate (CHX) from a prototype of controlled release drug device for root canal disinfection. Four different prototypes with different formulations were prepared. Group A (n = 12): the device (absorbent paper point) was loaded with CHX as control. Group B (n = 12): same as group A, but the device was coated with chitosan (Texan MedTech). In Groups C and D, the device was treated in the same way as group A and then coated 3 times with 5% PMMA (Group C, n = 12, Aldrich), or coated 3 times with 3% PLGA (Group D, n = 12, Sigma). The devices were randomly allocated to experimental groups of 12 each. All the prototypes of controlled release drug device were soaked in 3 mL distilled water. The concentrations of CHX were determined using a UV spectrophotometer. The surface characteristics of each prototype were observed using a scanning electron microscope. The result showed that release rate of CHX was the greatest in the noncoated group, followed by the chitosan-coated group, the PLGA-coated group, and the PMMA-coated group (P < 0.05). Pores were observed on the surface of the prototypes that were coated with PLGA and PMMA. When the pore size was smaller, the release rate was lower. These data indicate that polymer coating can control the release rate of CHX from the prototypes of controlled release drug device.

Nursing project management is widely used in different aspects of the society. However, whether the nursing project management can control the infections in the operation room (OR) is rarely reported. We evaluated the outcomes of surgical patients after implementing a nursing project management program to provide new scientific ways to manage the OR infections. Overall, 382 patients, who underwent surgical treatment in Qilu Hospital of Shandong University, Shandong, China from May 2015 to January 2016, were enrolled as observation group. Besides, 347 cases were selected as control group. Patients in the observation group were treated with the nursing project management plan, while patients in the control group were treated with the routine operation-room nursing measures. The infection control rates in the OR, and the patient satisfaction with the nursing team postoperatively were both compared between the two groups of patients. The OR air, the surgical and personnel's hands surfaces were sampled for colony forming units, and all were found to be significantly of better quality (indicated by less colony forming units) in the observation group (P<0.001). In addition, there were 3 cases (0.79%) of post-operation infections in the observation group, while 12 cases (3.46%) occurred in the control group. The overall infection rate of the observation group was significantly lower than that of the control group (P = 0.011); and the satisfaction of patients with the nursing team in the observation group was significantly higher than that of the patients in the control group ( P = 0.001). It is worth popularizing and applying a good nursing project management plan for surgical patients in hospitals.

Studies of the neurobehavioral effects of carbon nanomaterials, particularly those of multi-walled carbon nanotubes (MWCNTs), have concentrated on cognitive effects, but data are scarce. The aim of this study was to assess the influence of MWCNTs on a number of higher nervous system functions of Wistar rats. For a period of 10 days, two experimental groups were fed with MWCNTs of different diameters (MWCNT-1 group, 8–10 nm; MWCNT-2 group, 18–20 nm) once a day at a dosage of 500 mg/kg. In the open-field test, reductions of integral indications of researching activity were observed for the two MWCNT-treated groups, with a parallel significant (P<0.01) increase in stress levels for these groups compared with the untreated control group. In the elevated plus-maze test, integral indices of researching activity in the MWCNT-1 and MWCNT-2 groups reduced by day 10 by 51 and 62%, respectively, while rat stress levels remained relatively unchanged. In the universal problem solving box test, reductions in motivation and energy indices of researching activity were observed in the two experimental groups. Searching activity in the MWCNT-1 group by day 3 was reduced by 50% (P<0.01) and in the MWCNT-2 group the relevant reduction reached 11.2%. By day 10, the reduction compared with controls, was 64% (P<0.01) and 58% (P<0.01) for the MWCNT-1 and MWCNT-2 groups, respectively. In conclusion, a series of specific tests demonstrated that MWCNT-treated rats experienced a significant reduction of some of their cognitive abilities, a disturbing and worrying finding, taking into consideration the continuing and accelerating use of carbon nanotubes in medicine and science.

Objective Comparison of the total oxidant status (TOS), total antioxidant status (TAS) and paraoxonase (PON1) serum levels in patients with nasal septum deviation (NSD) and healthy subjects. Methods The TAS, TOS, and PON1 serum levels of 47 patients with NSD (mean age 35.3) and 50 healthy subjects (mean age 37.8) were compared in this study. Results We found significantly higher TAS levels in the control group (p<0.001). The mean TAS value was 1.196 mmoL/L in the control group, whereas it was 1.046 mmoL/L in the NSD group. On the other hand, TOS was significantly higher in the NSD group (p<0.001). We found that the mean TOS value was 6.600 mmoL/L in the control group, and 20.194 mmoL/L in the NSD group. The NSD and control groups had similar PON1 levels (p=0.446). The mean PON1 value was 279.64 U/L in the control group, and 324.21 U/L in the NSD group. Conclusion We detected higher TOS and lower TAS levels in patients with NSD compared to healthy subjects. These results indicate that patients with NSD are exposed to oxidative stress. PMID:29392069

The purpose of this study was to investigate the effects of pelvic floor muscle exercise using electric stimulation and biofeedback on maximum pressure of vaginal contraction, vaginal contraction duration and sexual function in women who have had vaginal rejuvenation. The research design was a non-equivalent control group non-synchronized design study. Participants in this study were women who had vaginal rejuvenation at C obstetrics and gynecology hospital. The 15 participants in the experimental group were given pelvic floor muscle exercise using electric stimulation and biofeedback and the 15 participants in the control group received self pelvic floor muscle exercise. For maximum pressure of vaginal contraction, the experimental group showed a statistically significant increase compared to than the control group (t=5.96, p<.001). For vaginal contraction duration, the experimental group also showed a statistically significant increase compared to the control group (t=3.23, p=.003). For women's sexual function, the experimental group showed a significant increase when compared to the control group in total sexual function scores (t=3.41, p=.002). The results indicate that pelvic floor muscle exercise with electric stimulation and biofeedback after vaginal rejuvenation is effective in strengthening vaginal contraction pressure, vaginal contraction and that it also positively functions to increase women's sexual function.

This study was to examine the effects of foot reflexion massage on sleep disturbance, depression disorder, and the physiological index of the elderly in nursing homes. The research design was a non-equivalent control group pretest-posttest quasi-experimental study. The subjects in this study were 50 elderly people who resided in two different nursing homes in the same region. An experimental group and a control group were organized with 25 subjects respectively, and foot reflexion massage was provided for 12 sessions, 30 minutes per session. The selected dependent variables were sleep disturbance, depression disorder, and physiological indices(blood plasma serotonin, serum cortisol), which were all measured before and after foot reflexion massage was offered. Data analysis included chi2-test, t-test, paired t-test, and ANCOVA, using the SPSS program package. 1. The experimental group improved sleep quality more than the control group. 2. The experimental group had less depression disorder than the control group. 3. The experimental group had higher serotonin levels than the control group. It's necessary to give foot reflexion massage as a successful nursing intervention to elderly who undergo a change in sleep, and suffer from a depression disorder due to a deterioration in sleep.

Previous studies have indicated a correlation between indication for cholecystectomy and long-term gastrointestinal quality-of-life (QoL). The aim of the present study was to compare QoL in a post-cholecystectomy cohort with the background population and with historical controls. A post-cholecystectomy study group (on average 4 years after cholecystectomy) was compared with a control group from the background population using the Gastrointestinal Quality-of-Life Index (GIQLI). EQ-5D scores were compared with expected scores derived from recent historical data. The post-cholecystectomy study group (N = 451) had better QoL measured by the EQ-5D compared with historical controls (p < 0.001), similar total GIQLI scores as the control group (N = 390), but scored worse on the GIQLI gastrointestinal symptoms subscale score (p < 0.001). The results include an item-by-item breakdown of the GIQLI questionnaire where the scores for diarrhea, bowel urgency, bloating, regurgitation, abdominal pain, flatus, fullness, nausea, uncontrolled stools, belching, heartburn, restricted eating, and bowel frequency were found to be significantly lower (i.e. worse) in the post-cholecystectomy cohort than in the control group. The opposite was true for relationships, endurance, sexual life, physical strength, feeling fit, not being frustrated by illness, and being able to carry out leisure activities, i.e. items related to general performance and well-being. In this study, QoL after cholecystectomy was good, but there was an increased prevalence of gastrointestinal symptoms compared to the background population.

Using remote sensing technique, we investigated real-time Nostoc sphaeroides Kütz (Cyanobacterium) in Closed System under microgravity by SHENZHOU-2 spacecraft in January 2001. The experiments had 1 g centrifuges in space for control and ground control group experiments were also carried out in the same equipments and under the same controlled condition. The data about the population growth of Nostoc sp. of experiments and temperature changes of system were got from spacecraft every minute. From the data, we can find that population growth of Nostoc sp. in microgravity group was higher than that of other groups in space or on ground, even though both the control 1 g group in space and 1 g group on ground indicated same increasing characteristics in experiments. The growth rate of 1.4 g group (centrifuged group on ground) was also promoted during experiment. The temperature changes of systems are also affected by gravity and light. Some aspects about those differences were discussed. From the discussion of these results during experiment, it can be found that gravity is the major factor to lead to these changes.

1. The effects of ascorbic acid (L-ascorbic acid) and melatonin supplementation on performance, carcase characteristics, malondialdehyde (MDA) as lipid peroxidation indicator, ascorbic acid, retinol, tocopherol and mineral status in the Japanese quail (Coturnix coturnix japonica) exposed to high ambient temperature were evaluated. 2. Two hundred and forty Japanese quails (10 d old) were randomly assigned to 8 treatment groups consisting of 10 replicates of three birds each. The birds were kept in a temperature-controlled room at 22 degrees C (Thermoneutral, TN groups) or 34 degrees C (for 8 h/d; 09:00 to 17:00 h; Heat stress, HS groups). Birds in both TN and HS were fed either a basal (control) diet or the basal diet supplemented with 250 mg of L-ascorbic acid/kg of diet (Ascorbic acid group), 40 mg of melatonin/kg of diet (Melatonin group) or both (Ascorbic acid + Melatonin group). 3. Supplementing heat-stressed quails with ascorbic acid and melatonin improved performance compared with the control group. Effects generally were greatest in quails supplemented with both ascorbic acid and melatonin. 4. Although supplementation did not consistently restore the concentrations of serum ascorbic acid, retinol and tocopherol to those of TN groups, these concentrations increased significantly with supplementation. Furthermore, serum and liver MDA and serum cholesterol and glucose concentrations were lower in the supplemented groups than in the heat-stressed controls. 5. Within each environment, excretion of Ca, P, Mg, Zn, Fe and Cr were lowest in the combination group and, in all cases, highest in the HS group. Interactions between diet and temperature were detected for live weight gain, cold carcase weight, MDA, ascorbic acid, tocopherol concentrations and excretion of zinc. 6. The results of the study indicate that ascorbic acid and melatonin supplementation attenuate the decline in performance and antioxidant and mineral status caused by heat stress and such supplementation may offer protection against heat-stress-related depression in performance of Japanese quails.

According to high incidence and prevalence of pressure ulcers worldwide, the purpose of this study is using of non-thermal atmospheric plasma as a novel therapy for pressure ulcers. Cold plasma was produced by applying a high-voltage (5 kV) and high-frequency (25 kHz), to helium gas. Under general anesthesia and sterile conditions, two circular magnets were used to create pressure ulcers on the dorsal skin of adult rats. The wounds were divided randomly into control and plasma-treated groups. Animals in the plasma-treated group received plasma radiation for 5 days, each day 3 times and every time 60 s. Mechanical assays were performed to determine plasma effects on the mechanical strength of the repaired tissue. The results showed that mechanical strength of repaired wound in the plasma-treated group was significantly higher than that in the control group (p < 0.05). In addition, evidence from histological studies indicates a significantly accelerated wound re-epithelialization in comparison with the control group; angiogenesis and fibrosis (collagen synthesis) were also significantly increased and the inflammation phase of wound healing was shorter in the plasma-treated group. The plasma treatment also resulted in significant wound contraction and acceleration of wound healing. The findings of present study indicate the effects of cold plasma on pressure ulcer treatment.

Platelets play a major role in thromboembolic events. Increased mean platelet volume (MPV) indicates higher platelet reactivity and also a tendency to thrombosis. Patent foramen ovale (PFO), persistence of the fetal anatomic shunt between right and left atria, is strongly associated with cryptogenic stroke. The aim of this study is to determine the relationship between MPV and PFO and if such an association exists, whether higher MPV levels may require antiplatelet therapy before a thromboembolic event happens, together with a literature review. Thirty patients (15 women, 15 men), free of any cerebrovascular events, were diagnosed with PFO by transesophageal echocardiography (TEE), enrolled as the study group. Thirty consecutive patients (16 women and 14 men), who were diagnosed as normal in TEE, were enrolled as the control group. These two groups were compared according to MPV and anatomical features of the right atrium. There was no significant difference between study and control groups in clinical features and also no difference was observed in platelet counts; however, MPV in the PFO group was significantly higher than the control group (8.38 ±0.93 fl and 7.45 ±0.68 fl respectively). Our results indicate that elevated MPV may be detected in patients with PFO. This might be one of the explanations for the relationship between PFO and cryptogenic stroke; however, larger cohorts are warranted in order to define further mechanisms.

This study aimed to investigate the effects of 6 wk oral supplementation of beta-hydroxy-beta-methylbutyrate (HMB) and HMB combined with creatine monohydrate (HMBCr) on indices of health in highly trained athletes. Elite, male rugby league players (n=28) were allocated to 1 of 3 groups: a control group (n=6), a HMB group (3 g/d; n=11), or a HMBCr group (3 g/day HMB, 3 g/d Cr; n=11). Testing prior to, and immediately following, supplementation included a full blood count, plasma testosterone and cortisol, blood electrolytes, lipids, urea and glucose, sperm count and motility, and assessment of psychological state. A 3 x 2 factorial ANOVA revealed no effect of HMB or HMBCr on any of the measured parameters except minor changes in blood bicarbonate and blood monocyte and lymphocyte counts. Blood bicarbonate was significantly decreased in the HMB post-supplementation sample compared to the control and HMBCr groups. Blood monocyte and lymphocyte counts showed no within-group changes for HMB or HMBCr supplementation but were significantly different from the control. However, the majority of these readings remained within normal range. HMB and HMBCr were concluded to have no adverse effects on the parameters evaluated in this study when taken orally by highly trained male athletes over a 6-wk period.

Studies have shown significant relationship between health conditions and attachment. This study aimed to examine an attachment-based intervention model named mother-child-disease triangle (MCDT) on health indices in children with chronic disease and their mothers. This randomized trial study included 22 volunteer children aged 12-18 years undergoing medical treatment for a chronic disease and their mothers. After evaluation by 28-form General Health Questionnaire (GHQ-28), inventory of parent and peer attachment (IPPA), 28-form Child Health Questionnaire (CHQ-28) and Illness Perception Questionnaire (IPQ), the mother-child dyads were paired on the basis of IPPA scores. These pairs were then randomly assigned to an experimental or control group. The experimental group received ten 90-min sessions of MCDT over a 7-week period. Meanwhile, the control group received ten simple conversational sessions as a dummy intervention. In accordance with this study's pre-test/post-test design, both groups were evaluated once again after completing their respective treatment. Multivariate analysis of covariance (MANCOVA) showed members of the experimental group to have significantly stronger attachment and better physiological and psychosocial health than those in the control group. These findings suggest that attachment-based interventions can be used to improve the effectiveness of treatment among children with chronic disease and their mothers.

To evaluate a case management (CM) model for people with mild dementia, whereby resources within the family and in the community were mobilized and optimally used. Community dwelling psychiatric and geriatrics outpatients with mild dementia were randomized to receive CM by a trained occupational therapist for 4 months (CM group, N = 59) or usual care only (control group, N = 43). Primary outcome indicators included the Zarit Burden Scale (ZBI), General Health Questionnaire (GHQ), and Personal Well-Being Index for Adult (PWI-A) of the family caregivers. Secondary outcome indicators included the Mini-Mental State Examination (MMSE), Neuropsychiatric Inventory (NPI), Cornell Scale for Depression in Dementia (CSDD), and Personal Well-Being Index for Intellectually Disabled (PWI-ID) of the demented subjects as measured at fourth and twelfth months. CSDDis reduced in the CM group at fourth month, but not at twelfth month. The changes in outcome variables of persons with dementia did not differ between the groups (Mann-Whitney U-test, p > 0.05). At follow-up, CM group used more day care and domestic helpers than control group (chi (2), p > 0.05). Case management for Chinese persons with mild dementia outpatients did not show significant effects in reducing caregiver burden, but encouraged family caregivers to seek external support.

The aim of the study was comparison of perception of attachment patterns between adolescent girls suffering from anorexia nervosa (restrictive type), bulimia nervosa and healthy peers. Moreover, we tried to find the differences between the groups in self-esteem and identification with the culture-defined sex role. We examined 40 patients with anorexia, 32 with bulimia and 63 girls from the comparison group. Three questionnaires were used: Parental Bonding Instrument, The Culture-Free Self-Esteem Inventory and Psychological Sex Inventory. Results indicate that the parents' emotional commitment in relations with daughters from the clinical sample is weaker, and they are controlled by parents more then those from the control group. In all groups, the mothers' emotional commitment correlates positively with daughters' social self-esteem. In the anorectic group, fathers' control correlates negatively with daughters' identification with the culture-defined feminine role. In the bulimic group, fathers' emotional commitment correlates positively with self-esteem as well as daughters' identification with the culture-defined masculine role. The results concerning the bonds between the ED patients and their parents indicating dysfunctions of the bonds are generally consistent with the data from literature. Additionally they show the relationship between quality of the bonds between the patients and parents and its influence on development of self-evaluation and a sense of feminity/masculinity in anorectic and bulimic girls.

The purpose of this study is to investigate the effectiveness of guided-inquiry approach in science classes over existing science and technology curriculum in developing content-based science achievement, science process skills, and attitude toward science of grade level 6 students in Turkey. Non-equivalent control group quasi-experimental design was used to investigate the treatment effect. There were 162 students in the experimental group and 142 students in the control group. Both the experimental and control group students took the Achievement Test in Reproduction, Development, and Growth in Living Things (RDGLT), Science Process Skills Test, and Attitudes Toward Science Questionnaire, as pre-test and post-test. Repeated analysis of variance design was used in analyzing the data. Both the experimental and control group students were taught in RDGLT units for 22 class hours. The results indicated the positive effect of guided-inquiry approach on the Turkish students' cognitive as well as affective characteristics. The guided inquiry enhanced the experimental group students' understandings of the science concepts as well as the inquiry skills more than the control group students. Similarly, the experimental group students improved their attitudes toward science more than the control group students as a result of treatment. The guided inquiry seems a transition between traditional teaching method and student-centred activities in the Turkish schools.

Poor adherence and a lack of understanding of medication instructions for oral antidiabetic use are key factors that inhibit the control of glycemic levels. The aforementioned situation needs intervention to improve medication adherence and the therapy. This study was conducted with a quasi-experimental design with prospective data collection. The subjects of this study were 50 outpatients with type 2 diabetes melitus (T2DM) who had received oral antidiabetic medicine therapy at least six months prior to adherence measurement. The patients were classified into two groups—the control group and the intervention group. The intervention group received Short Message Service (SMS) messages of diabetes education, while the control group did not. Data collection was conducted by doing interviews and administering the Morisky Medication Adherence Scale (MMAS) questionnaire. The results showed the increase in adherence in the intervention group as 1.15 ± 1.04 and that in the control group as 0.72 ± 0.90. These results indicated that there were significant differences in MMAS score between the control and intervention groups (p < 0.05). The decrease in fasting blood glucose and glucose measured 2 h postprandially was greater in the intervention group than that in the control group. It was concluded that the provision of education through SMS had a positive effect on medication adherence and glycemic levels. PMID:28545222

The aim of this study is to investigate the entrepreneurial traits of school children in the city of Tehran. For this purpose, 48 students were selected with an average IQ between 90 and 119. Ranging from 7th to 12th grades, all the subjects were assessed using Nowicki-Strickland's Locus of Control Scale (N-SLCS), Torrance Tests of Creative Thinking (TTCT), and Hyperkinetic Syndrome Assessment Method (HKSD). The obtained results were then organized and categorized into three groups. One of the groups was randomly chosen as experimental and the other as the control group and the last play group. In this empirical study, the students received Sensory Motor Rhythm (SMR) and Beta neurofeedback for 20 sessions. The play group was assigned to play mind games for 20 sessions. At the same time, the control group received no experiments. After the end of the experiments, all the students in three groups were reassessed by Torrance Tests of Creative Thinking, Hyperkinetic Syndrome Assessment Method, and Nowicki-Strickland's Locus of Control Scale. The results from MANOVA showed that the neurofeedback group had demonstrated a meaningful change in creativity and locus of control while the adaptability of risk-taking was on a meaningful level for the experimental group. The results also indicate an improvement in creativity for the neurofeedback group in comparison with the play group on a 0.02 meaningful level. Similarly, the results suggest an improvement in creativity for the neurofeedback group on a 0.000 meaningful level in comparison with the control group. This is while the play group and the control group do not show any meaningful difference. The results also show an improvement in the internal locus of control for the neurofeedback group in comparison with the play group on a 0.032 meaningful level; while, it is meaningful on a 0.01 level for the neurofeedback group in comparison with the control group. The findings for the play group and control group do not show any meaningful difference. The paper concludes that neurofeedback training can be used for increasing the level of entrepreneurial traits in students.

The purpose of the present study was the assessment of the serum concentration of antioxidant microelements-zinc, copper, selenium, manganese, and Cu/Zn ratio in children and adolescents with myopia. Eighty-three children were examined (mean age 14.36 ± 2.49 years) with myopia. The control group was 38 persons (mean age 12.89 ± 3.84 years). Each patient had complete eye examination. The serum concentration of zinc, copper, manganese, and selenium was determined by atomic absorption spectrometry. Cu/Zn ratio, which is the indicator of the oxidative stress, was also calculated. The average serum concentration of zinc in myopic patients was significantly lower (0.865 ± 0.221 mg L -1 ) in comparison to the control group (1.054 ± 0.174 mg L -1 ). There was significantly higher Cu/Zn ratio in myopic patients (1.196 ± 0.452) in comparison to that in the control group (0.992 ± 0.203). The average serum concentration of selenium in the study group was significantly lower (40.23 ± 12.07 μg L -1 ) compared with that in the control group (46.00 ± 12.25 μg L -1 ). There were no essential differences between serum concentration of copper and manganese in the study group and the control group. Low serum concentration of zinc and selenium in myopic children may imply an association between insufficiency of these antioxidant microelements and the development of the myopia and could be the indication for zinc and selenium supplementation in the prevention of myopia. Significantly, higher Cu/Zn ratio in the study group can suggest the relationship between myopia and oxidative stress.

Bullying is characterized by intentional, repetitive, and persistent aggressive behavior that causes damage to the victim. Many studies investigate the social and emotional aspects related to bullying, but few assess the cognitive aspects it involves. Studies with aggressive individuals indicate impairment in executive functioning and decision-making. The objective of this study was to assess hot and cold executive functions in children who experience bullying. A total of 60 children between 10 and 11 years of age were included in the study. They were divided into four groups: aggressors (bullies), victims, bully-victims, and control. Tests for decision-making, inhibitory control, working memory, and cognitive flexibility were used. The bully group made more unfavorable choices on the Iowa Gambling Task, which may indicate difficulties in the decision-making process. The victim group took longer to complete the Trail Making Test (Part B) than aggressors, suggesting lower cognitive flexibility in victims. The hypothesis that aggressors would have lower performance in other executive functions such as inhibitory control, working memory, and cognitive flexibility has not been confirmed. This study indicates that bullies have an impairment of hot executive functions whereas victims have a comparatively lower performance in cold executive functions. In addition to social and cultural variables, neurocognitive and emotional factors seem to influence the behavior of children in bullying situations. PMID:27616998

2016-08-01

Adolescence is a critical time for the development of psychological well-being. Weight gain and the emergence of body image concerns during this period can lead to the development of negative psychological states. To explore this issue, we examined the relationship between weight control behavior (WCB; ie, trying to lose, gain, stay the same, or do nothing about weight) and levels of depression and self-esteem. Adolescents (508 boys, 502 girls; Mage  = 12.32 ± .88 years) completed a survey that assessed WCB, depression, and self-esteem. Descriptive discriminant analysis was used to analyze WCB group differences on psychological well-being. Multivariate post hoc analysis further examined group differences. Structure coefficients indicated the relative importance of each dependent variable in boys and girls. Results indicated that, among both sexes, WCB was significantly related to depression and self-esteem. Individuals trying to lose weight had lower levels of psychological well-being than the other groups. Adolescents trying to lose weight reported the lowest psychological well-being scores whereas those not doing anything to control weight reported the highest levels of psychological well-being. These findings have important implications for screening and education programs designed to monitor and support adolescent psychological well-being. © 2016, American School Health Association.

The purpose of this study was to evaluate peripheral neural impairment in leprosy patients by ultrasonography (US). The cross-sectional areas (CSAs) of the median (M), ulnar (U) and common fibular (CF) nerves were compared in 71 leprosy patients and 29 healthy controls, and the data were analyzed between the leprosy, multibacillary (MB)/paucibacillary (PB), reaction (R)/no reaction (NR), disability (D)/no disability (ND), and longer/shorter duration groups after treatment. We found that for the nerves located in upper limbs, the CSAs were significantly increased in the leprosy patients vs the controls; the PB group vs the MB group; the R group vs the NR group; the ND group vs the D group; and the longer duration group vs the shorter duration group at some positions of the M nerve and U nerve. In contrast, for the nerves located in lower limbs, the CSAs were significantly reduced in the leprosy patients vs the controls and in the longer duration group vs the shorter duration group at some positions of the CF nerve. This result indicated that nerve enlargement and neuratrophy coexist in leprosy patients.

We discuss the analytic and practical considerations in a large case-control study that had two control groups; the first control group consisting of partners of patients and the second obtained by random digit dialling (RDD). As an example of the evaluation of a general lifestyle factor, we present body mass index (BMI). Both control groups had lower BMIs than the patients. The distribution in the partner controls was closer to that of the patients, likely due to similar lifestyles. A statistical approach was used to pool the results of both analyses, wherein partners were analyzed with a matched analysis, while RDDs were analyzed without matching. Even with a matched analysis, the odds ratio with partner controls remained closer to unity than with RDD controls, which is probably due to unmeasured confounders in the comparison with the random controls as well as intermediary factors. However, when studying injuries as a risk factor, the odds ratio remained higher with partner control subjects than with RRD control subjects, even after taking the matching into account. Finally we used factor V Leiden as an example of a genetic risk factor. The frequencies of factor V Leiden were identical in both control groups, indicating that for the analyses of this genetic risk factor the two control groups could be combined in a single unmatched analysis. In conclusion, the effect measures with the two control groups were in the same direction, and of the same order of magnitude. Moreover, it was not always the same control group that produced the higher or lower estimates, and a matched analysis did not remedy the differences. Our experience with the intricacies of dealing with two control groups may be useful to others when thinking about an optimal research design or the best statistical approach.

To evaluate the efficacy of preoperative pelvic floor muscle training (PFMT) on histomorphometry, muscle function, urinary continence and quality of life of patients undergoing radical prostatectomy (RP). A prospective intervention clinical study was designed in 16 patients with indication of RP who were randomized into two groups. The Control Group received routine pre-surgical education (hygienic-dietary measures). The intervention group received a training session with supervised PFMT, three times a day, for four weeks, 30 days before the PR. Muscle function of the external urethral sphincter, contraction pressure of the levator ani, urinary continence and quality of life related to health (HRQoL) were evaluated before and after the intervention. At the end of the intervention and day of the surgery, samples of residual muscle tissue were obtained from the external sphincter muscle of the urethra for histomorphometric analysis. After the intervention, those participants who carried out PFMT showed an increase in the cross-sectional area of the muscle fibers of the external urethral sphincter (1,313 ± 1,075 μm(2)vs. 1,056 ± 844 μm(2), P=.03) and higher pressure contraction of the levator ani (F=9.188; P=.010). After catheter removal, 62% of patients in the experimental group and 37% in the control group showed no incontinence. After removal of the catheter, 75% of the experimental group did not require any pad compared to 25% in the control group (p=NS). There were no significant differences between the two groups in any of the HRQoL domains studied. Pre-surgical PFMT in patients with RP indication induces changes in the histology and function of the pelvic floor muscles, without changes in urogenital function and HRQoL. These results provide new evidence regarding the benefit of PFMT in preventing RP associated complications. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

To assess the influence of two persimmon cultivars on some atherosclerosis indices in rats fed cholesterol (Chol)-containing diets. Persimmon cultivars "Fuyu" and "Jiro" as supplementation to rats' diets were investigated in vitro to compare the contents of their bioactive compounds (polyphenols, flavonoids, flavanols, tannins, carotenoids, and ascorbic acid) and antioxidant potentials. In the in vivo investigation, 36 male Wistar rats were randomly divided into six diet groups, each with six rats: control, control/Fuyu, control/Jiro, Chol, Chol/Fuyu, and Chol/Jiro. During a period of 47 d (42 d of feeding and 5-d adaptation before the experiment) of the trial, rats in the control group were fed a basal diet and two additional control groups (control/Fuyu and control/Jiro) a basal diet plus 5% of lyophilized Fuyu and Jiro, respectively. The Chol, Chol/Fuyu, and Chol/Jiro rat groups were fed a basal diet supplemented with 1% Chol (Chol group) and 1% Chol plus 5% lyophilized Fuyu (Chol/Fuyu group) and plus 5% lyophilized Jiro (Chol/Jiro group), respectively. After completion of the experiment, the rats were anesthetized using Narcotan (halothane) and sacrificed and the atherosclerotic lesions in the aorta were assessed. The obtained results of the investigation of all six groups were compared. Testing of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triacylglycerols, total cholesterol in the liver, electrophoretic patterns of liver tissue, and three-dimensional fluorescence of serum protein fractions was performed. The polyphenols and tannins were significantly higher in the Fuyu cultivar (P<0.05). The antioxidant potential of persimmon Fuyu was higher than in the Jiro cultivar, but the difference was significant only according to the 2,2-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) assay (P<0.05). Supplementation of diets with 5% of the lyophilized Fuyu and Jiro hindered the increase in plasma lipids versus the Chol group (total cholesterol 19.4% and 9.5%, low-density lipoprotein cholesterol 25.6% and 13.1%, respectively, P<0.05) and hindered the decrease in plasma antioxidant activity versus the Chol group by 40.0% and 16.8% and by 39.6% and 11.3% for the ABTS and 1,1-diphenyl-2-picrylhydrazyl assays, respectively. The atherosclerotic lesions in the aortas of the Chol/Fuyu and Chol/Jiro groups were significantly less than in the Chol group (P<0.05). Electrophoresis of the proteins from rats' liver tissue showed changes in 14-kDa bands after persimmon supplementation. A shift in maximum wavelengths in three-dimensional fluorescence of serum protein fractions after persimmon supplementation was found in comparison with the control group and an increase in fluorescence intensity compared with the Chol groups. The contents of polyphenols and tannins were significantly higher in the Fuyu cultivar (P<0.05). The antioxidant potentials of Fuyu were higher than those of the Jiro cultivar, but the difference was significant only according to the ABTS assay (P<0.05). Supplementation of 5% lyophilized Fuyu and Jiro to diets of rats fed Chol-containing diets 1) hindered the increase in plasma lipids levels and the decrease in plasma antioxidant activity and 2) significantly decreased the atherosclerotic lesions in the aorta (P<0.05). Electrophoretic patterns of liver tissue and fluorescence spectra can be used as additional biomarkers for determination of atherosclerosis indices. Copyright © 2011 Elsevier Inc.

To assess efficacy and tolerability of sildenafil citrate on utero-placental blood flow and fetal growth in pregnancies complicated by fetal growth restriction (FGR). From March 2015, a randomized controlled trial of 54 patients at 24 weeks or more complicated by FGR and abnormal Doppler indices were randomly allocated 1:1 into an intervention arm (receive sildenafil citrate, 50 mg) or a control arm (receive placebo). The primary outcomes were changes occurred in the Doppler parameters 2 h following drug administration. Baseline characteristics were similar between groups. Significant difference was observed in the Delta uterine and umbilical Doppler indices among sildenafil group as compared to placebo group (p < 0.001). Middle cerebral Doppler indices, however, decreased significantly after sildenafil, which could be the result of shifting more blood to improve the utero-placental perfusion. No difference regarding Delta cerebro-placental ratio among both groups (p = 0.979). Sildenafil was also associated with pregnancy prolongation (p = .0001), increased gestational age at delivery (p = .004), improved neonatal weight (p = .0001), and less admission to neonatal intensive care unit (p = .03). No adverse effects reported in both treatment arms. Sildenafil citrate, by its vasodilator effect, can improve utero-placental blood flow in pregnancies complicated by FGR and abnormal Doppler. gov Registry: NCT02362399.

This study assessed the blood pressure (BP) of normotensive subjects and subjects with pharmacologically controlled hypertension after sodium bicarbonate jet prophylaxis. Forty subjects were divided into 2 groups: a normotensive control group (n = 20) and a hypertensive group (n = 20). Blood pressure measurements were conducted at 4 timepoints: prior to the dental prophylaxis (T0), immediately after treatment (Ti), 15 minutes after treatment (T15), and 30 minutes after treatment (T30). The systolic BP (SBP) values for both groups were significantly increased at Ti (P < 0.05) and returned to their initial state at T15. Both groups also showed a significant increase in diastolic BP (DBP) values at Ti (P < 0.05); however, the basal conditions in hypertensive subjects were not restored until T30, whereas the values for normotensive subjects were restored at T15. The results indicated that systemic BP changed significantly after sodium bicarbonate jet prophylaxis in both study groups; while initial SBP values were restored by 15 minutes in both groups, the return to initial DBP values took longer in the hypertensive group than in the normotensive group.

[Purpose] This study investigated the effect of aquatic proprioceptive neuromuscular facilitation (PNF) patterns in the lower extremity on balance and activities of daily living (ADL) in stroke patients. [Subjects] Twenty poststroke participants were randomly assigned to an experimental group (n = 10) or a control group (n = 10). The experimental group performed lower extremity patterns in an aquatic environment, and the control group performed lower extremity patterns on the ground. Both exercises were conducted for 30 minutes/day, 5 days/week for 6 weeks. Balance was measured with the Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), Functional Reach Test (FRT), and One Leg Stand Test (OLST). Activities of daily living were measured with the Functional Independence Measure (FIM). A paired t-test was used to measure pre- and post-experiment differences, and an independent t-test was used to measure between-group differences. [Results] The experimental and control groups showed significant differences for all pre- and post-experiment variables. In the between-group comparison, the experimental group was significantly difference from the control group. [Conclusion] These results indicate that performing aquatic proprioceptive neuromuscular facilitation patterns in the lower extremity enhances balance and ADL in stroke patients.

In this study, 2 experiments were conducted to investigate whether motivation and positive affect can alleviate ego depletion and to elucidate their possible mechanisms. In Experiment 1, a crossing-out-letter task was adapted to reach an ego depletion state for Chinese participants. Participants were then randomly assigned to the extrinsic motivation group, the positive affect group or the depletion control group. After the experimental treatment, a dumbbell task was used to measure participants' remaining self-regulatory resources. The results showed that participants in the motivation and positive affect groups performed better on the dumbbell task than participants in the depletion control group. Experiment 2 was similar to Experiment 1 except that participants were asked to perform an additional unexpected dumbbell task after a neutral video following the above procedure. The results of Experiment 1 were replicated; however, participants' performance on the additional dumbbell task differed. The positive affect group performed better than the depletion control group, indicating an increase in self-regulatory resources and thus supporting the replenishment effect of positive affect. No significant difference was found between the motivation group and the depletion control group. © 2015 International Union of Psychological Science.

In Senegal, nutrition instruction was implanted in 1981 in the national curriculum of biology and has never been evaluated since. The purpose of this study, was to evaluate the effect of a six weeks nutrition instruction program on improving nutrition knowledge and nutrition attitudes in an experimental group including 81 subjects aged 16.7+/-1.2 years and a control group including 80 subjects aged 15.7+/-1.3 years. These subjects came respectively from third and fourth grade. A questionnaire on knowledge and one on attitudes were administered to the experimental group, before and after the nutrition instruction, while the control group, who did not received any nutrition instruction, also answered the questionnaires. Results indicate that the adjusted mean knowledge posttest scores did not significantly increase in the experimental group compared to the control group. In addition, the adjusted mean attitude postscores of the boys and girls of the experimental group on the attitude scale "Nutrition affects health" were significantly higher from that of the control group. An evaluation of the nutrition curriculum and the teaching methods is suggested in order to improve the effectiveness of this nutrition program.

This study examined whether a leisure education program could promote leisure autonomy and self-rated health (SRH) among older adults. A pretest-posttest randomized experimental design was conducted. Subjects were randomly assigned to either an experimental group (n = 30) or a control group (n = 30). Data related to leisure autonomy and SRH were collected shortly before and after the experiment. Pretest and posttest data were analyzed using an analysis of covariance. The results indicated that the average posttest scores of leisure autonomy and SRH in the experimental group were significantly higher than those in the control group. Implications of the results are discussed.

Among 10 subjects who practiced autogenic training (AT) and 10 subjects who practiced transcendental meditation (TM), compared to 10 control subjects during 40 minutes, have been observed the following results: --decrease in cortisol plasma level (reaching a minima of 2 g/100 ml), --decrease in prolactin plasma level, --the basal plasma level of cortisol and prolactin were significantly lower in the TM group. Lastly, the urinary catecholamines (UC) increase after 40 minutes of rest in the control group, whereas the UC decrease in the TA group and most certainly in the TM group. All these variations indicate a humoral modification which seems to be the opposite of the state induced by stress.

The purpose of this study was to examine the effect of an asthma education program on schoolteachers' knowledge. Pre-test-post-test experimental randomized controlled design was used. A multistage-cluster sampling technique was used to randomly select governorate, primary schools, and schoolteachers. Schoolteachers were randomly assigned either to the experimental group (n = 36) and attended three educational sessions or to the control group (n = 38) who did not receive any intervention. Knowledge about asthma was measured using the Asthma General Knowledge Questionnaire for Adults (AGKQA). The results indicated that teachers in the experimental group showed significantly (p < .001) higher knowledge of asthma in the first post-test and the second post-test compared with those in the control group. Implementing asthma education enhanced schoolteachers' knowledge of asthma. The asthma education program should target schoolteachers to improve knowledge about asthma. © The Author(s) 2014.

Learning to Control Actions: Transfer Effects following a Procedural Cognitive Control Computerized Training

PubMed Central

Shahar, Nitzan; Meiran, Nachshon

2015-01-01

Few studies have addressed action control training. In the current study, participants were trained over 19 days in an adaptive training task that demanded constant switching, maintenance and updating of novel action rules. Participants completed an executive functions battery before and after training that estimated processing speed, working memory updating, set-shifting, response inhibition and fluid intelligence. Participants in the training group showed greater improvement than a no-contact control group in processing speed, indicated by reduced reaction times in speeded classification tasks. No other systematic group differences were found across the different pre-post measurements. Ex-Gaussian fitting of the reaction-time distribution revealed that the reaction time reduction observed among trained participants was restricted to the right tail of the distribution, previously shown to be related to working memory. Furthermore, training effects were only found in classification tasks that required participants to maintain novel stimulus-response rules in mind, supporting the notion that the training improved working memory abilities. Training benefits were maintained in a 10-month follow-up, indicating relatively long-lasting effects. The authors conclude that training improved action-related working memory abilities.

To examine whether a preoperative cognitive behavioural therapy (CBT) intervention exceeds usual care in the improvements of dysfunctional eating behaviours, mood, affective symptoms and body weight 1 year after bariatric surgery. This is a 1-year follow-up of a single centre parallel-group randomised controlled trial ( http://clinicaltrials.gov/ct2/show/NCT01403558). A total of 80 (55 females) patients mean (SD) age 44 (10) years were included. The intervention group received 10 weeks of CBT prior to bariatric surgery, and the control group received nutritional support and education. Both groups were assessed at baseline (T0), post CBT intervention/preoperatively (T1), and 1 year postoperatively (T2). Using a mixed modelling statistical approach, we examined if the CBT group improved more across time than the control group. Our hypothesis was not supported as both groups had comparable improvements in all outcomes except for anxiety symptoms. Body weight declined by 30.2 % (37.3 kg) in the CBT group and by 31.2 % (40.0 kg) in the control group from baseline to follow-up, p = 0.82. There were statistically significant reductions in anxiety and depression symptoms in the CBT group between T0 and T1 and between T1 and T2 for depression only. However, in the control group, the anxiety score did not change significantly. The CBT group showed an earlier onset of improvements in all eating behaviours and affective symptoms than the control group. The 10-week CBT intervention showed beneficial effects preoperatively, but the non-significant group differences postoperatively indicate a genuine effect of surgery.

An open-label randomized controlled trial was conducted to clarify the effect of eldecalcitol (ED) on body balance and muscle power in postmenopausal osteoporotic women treated with bisphosphonates. A total of 106 postmenopausal women with osteoporosis (mean age 70.8 years) were randomly divided into two groups (n=53 in each group): a bisphosphonate group (control group) and a bisphosphonate plus ED group (ED group). Biochemical markers, unipedal standing time (body balance), and five-repetition chair-rising time (muscle power) were evaluated. The duration of the study was 6 months. Ninety-six women who completed the trial were included in the subsequent analyses. At baseline, the age, body mass index, bone mass indices, bone turnover markers, unipedal standing time, and chair-rising time did not differ significantly between the two groups. During the 6-month treatment period, bone turnover markers decreased significantly from the baseline values similarly in the two groups. Although no significant improvement in the unipedal standing time was seen in the ED group, compared with the control group, the chair-rising time decreased significantly in the ED group compared with the control group. The present study showed that ED improved the chair-rising time in terms of muscle power in postmenopausal osteoporotic women treated with bisphosphonates. PMID:24476669

Anger and aggression are frequent problems in deployed military personnel. A lowered threshold of perceiving and responding to threat can trigger impulsive aggression. This can be indicated by an exaggerated startle response. Fifty-two veterans with anger and aggression problems (Anger group) and 50 control veterans were tested using a startle experiment with 10 startle probes and 10 prepulse trials, presented in a random order and with a random interval between the trials. Predictors (demographics, Trait Anger, State Anger, Harm Avoidance and Anxious Arousal) for the startle response within the Anger group were tested. Increased EMG responses were found to the startle probes in the Anger Group compared to the Control group, but not to the prepulse trials. Furthermore, Harm Avoidance and State Anger predicted the increased startle reflex within the Anger group, whereas Trait Anger was negatively related to the startle reflex. These findings indicate that threat reactivity is increased in anger and aggression problems. These problems are not only caused by an anxious predisposition, the degree of anger also predicts the startle reflex. Copyright © 2016 Elsevier B.V. All rights reserved.

Here we analyze gray matter indices before and after completing a challenging adaptive cognitive training program based on the n-back task. The considered gray matter indices were cortical thickness (CT) and cortical surface area (CSA). Twenty-eight young women (age range 17–22 years) completed 24 training sessions over the course of 3 months (12 weeks, 24 sessions), showing expected performance improvements. CT and CSA values for the training group were compared with those of a matched control group. Statistical analyses were computed using a ROI framework defined by brain areas distinguished by their genetic underpinning. The interaction between group and time was analyzed. Middle temporal, ventral frontal, inferior parietal cortices, and pars opercularis were the regions where the training group showed conservation of gray matter with respect to the control group. These regions support working memory, resistance to interference, and inhibition. Furthermore, an interaction with baseline intelligence differences showed that the expected decreasing trend at the biological level for individuals showing relatively low intelligence levels at baseline was attenuated by the completed training.

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.

Yardley, L; Beech, S; Zander, L; Evans, T; Weinman, J

1998-01-01

BACKGROUND: 'Vestibular rehabilitation' (VR) is an increasingly popular treatment option for patients with persistent dizziness. Previous clinical trials have only evaluated the effects of specialist therapy programmes in small, selective, or uncontrolled patient samples. AIM: To determine the benefits of VR compared with standard medical care, using a brief intervention for dizzy patients in primary care. METHOD: Adults consulting their general practitioner (GP) with dizziness or vertigo were randomly assigned to treatment or control groups. Patients in both groups received the same evaluation at baseline, six-week follow-up, and six-month follow-up, comprising examination of nystagmus, postural control, and movement-provoked dizziness, and a questionnaire assessment of subjective status, symptoms, handicap, anxiety, and depression. At baseline and six weeks later, the treatment group also received an individualized 30-minute therapy session, in which they were taught head, eye, and body exercises designed to promote vestibular compensation and enhance skill and confidence in balance. RESULTS: The treatment group (n = 67) improved on all measures, whereas the control group (n = 76) showed no improvement, resulting in a significant difference between the two groups on physical indices of balance and subjective indices of symptoms and distress. Odds ratios for improvement in treated patients relative to untreated patients were 3.1:1 at six weeks (95% CI = 1.4-6.8) and 3.8:1 at six months (95% CI = 1.6-8.7). CONCLUSION: VR is a simple, inexpensive, and beneficial treatment, and may be an appropriate first stage of management for many dizzy patients in primary care. PMID:9667087

The neural mechanisms that give rise to hyperacusis, a reduction in loudness tolerance, are largely unknown. Some reports suggest that hyperacusis is linked to childhood hearing loss. However, the evidence for this is largely circumstantial. In order to rigorously test this hypothesis, we studied loudness changes in rats caused by intense noise exposure (12 kHz narrow band noise, 115 dB SPL, 4 h) at postnatal 16 days. Rats without noise exposure were used as controls. The exposed noise group (n = 7) showed a mean 40-50 dB hearing loss compared to the control group (n = 8) at high frequencies (>= 8 kHz) and less hearing loss at lower frequencies. Loudness was evaluated using sound reaction time and loudness response functions in an operant conditioning-based behavioral task using narrow-band noise (40-110 dB SPL, centered at 2, 4 and 12 kHz). Interestingly, the sound reaction time of the noise group was significantly shorter than the control group at supra-threshold levels. The average reaction time was less than 100 ms in the noise group at 100 dB SPL, which was three times shorter than the control group. Our results indicate that early noise-induced hearing loss leads to a significant increase of loudness, a behavior indicative of hyperacusis. Our results are consistent with clinical reports suggesting that hearing loss at an early age is a significant risk factor for hyperacusis. Published by Elsevier B.V.

Background The purpose of the present investigation was to determine if the salivary counts of 40 common oral bacteria in subjects with an oral squamous cell carcinoma (OSCC) lesion would differ from those found in cancer-free (OSCC-free) controls. Methods Unstimulated saliva samples were collected from 229 OSCC-free and 45 OSCC subjects and evaluated for their content of 40 common oral bacteria using checkerboard DNA-DNA hybridization. DNA counts per ml saliva were determined for each species, averaged across subjects in the 2 subject groups, and significance of differences between groups determined using the Mann-Whitney test and adjusted for multiple comparisons. Diagnostic sensitivity and specificity in detection of OSCC by levels of salivary organisms were computed and comparisons made separately between a non-matched group of 45 OSCC subjects and 229 controls and a group of 45 OSCC subjects and 45 controls matched by age, gender and smoking history. Results Counts of 3 of the 40 species tested, Capnocytophaga gingivalis, Prevotella melaninogenica and Streptococcus mitis, were elevated in the saliva of individuals with OSCC (p < 0.001). When tested as diagnostic markers the 3 species were found to predict 80% of cancer cases (sensitivity) while excluding 83% of controls (specificity) in the non-matched group. Diagnostic sensitivity and specificity in the matched group were 80% and 82% respectively. Conclusion High salivary counts of C. gingivalis, P. melaninogenica and S. mitis may be diagnostic indicators of OSCC. PMID:15987522

Improvements in medication use achieved by pharmacy generalists using a care bundle approach to antimicrobial stewardship are reported. A six-month prospective, repeated-treatment, quasi-experimental study involving three month-long intervention periods and three month-long control periods was conducted in the setting of an existing antimicrobial stewardship program at a large hospital. The intervention involved prospective audit and feedback conducted by pharmacy generalists who were trained in an antimicrobial stewardship care bundle approach. During control months, a pharmacy generalist who was not trained in antimicrobial stewardship rounded with the multidisciplinary team and provided standard-of-care pharmacy services. The primary endpoint was compliance with a care bundle of four antimicrobial stewardship metrics: documentation of indication for therapy in the medical record, selection of empirical therapy according to institutional guidelines, documented performance of indicated culture testing, and deescalation of therapy when indicated. Two-hundred eighty-six patients were enrolled in the study: 124 in the intervention group and 162 in the control group. The cumulative rate of full compliance with all care bundle components during the six-month study was significantly greater during intervention months than during control months (68.5% versus 45.7%, p < 0.001). After adjusting for infection type, antimicrobial stewardship provided by an intervention-group pharmacist was associated with improved care bundle compliance (adjusted odds ratio, 2.70; p < 0.001). No significant differences in patient outcomes during intervention and control months were detected. Pharmacy generalists trained to comply with a systematic care bundle approach enhanced the quality of antimicrobial management.

Statement of the Problem: Recently allogenic mesenchymal stem cells are proposed to have multipotential progenitor cell capabilities to differentiate into cementoblasts, osteoblasts, and periodontal ligament fibroblasts. Purpose: The aim of the present study was to compare the efficacy of human umbilical stem cells cultured on polylactic acid (PLA), polyglycolic acid (PGA) membrane with PLA/PGA membrane alone in the treatment of multiple gingival recession defects. Materials and Method: A total number of 14 cases of multiple gingival recession (Miller’s Class I or II) located in the anterior region were randomly selected and divided into test (stem cells in combination with PLA/PGA membrane) and control group (PLA/PGA membrane alone). Clinical parameters including gingival recession, probing pocket depth, clinical attachment level, and width of keratinized gingiva were recorded at baseline, and at 6 months postoperative. Results: At baseline, there was 2.28 mm and 2.14mm mean gingival recession at 16 sites and 14 sites in test and control groups respectively. At 6 months post-surgery, test group showed 1.57 mm mean reduction of gingival recession indicating 66% root coverage, while the control group showed 1.24mm mean reduction of gingival recession indicating 57% root coverage. Conclusion: In the present study, the stem cell with PLA/PGA membrane showed significantly higher mean root coverage compared to only PLA/PGA membrane group. PMID:28620633

Our objective was to evaluate the efficacy of a cultural adaptation of a social cognitive theory-based HIV behavioral prevention program among young rural-to-urban migrants in China. The intervention design and assessment were guided by the Protection Motivation Theory (PMT). The intervention was evaluated through a randomized controlled trial with 6-month and 12-month follow-ups. The primary behavioral outcome was the use of condoms. Other outcome measures include HIV knowledge, condom use knowledge, HIV-related perceptions (PMT constructs), and intention to use condom. The mixed-effects regression models for condom use with regular partners indicated that overall frequency of condom use, condom use in last three sexual acts and proper condom use increased over time for the participants but the increases were significantly greater among the intervention group than the control group at 6-month and 12-month follow-ups. The mixed-effects models for HIV-related perceptions indicated that extrinsic rewards, intrinsic rewards, and response costs decreased while vulnerability, severity, response efficacy, and self-efficacy increased over time for the intervention group. The increases in HIV knowledge, condom use knowledge, and intention to use condom were also significantly greater among the intervention group than the control group. The data in the current study suggested efficacy of a social cognitive theory-based behavioral intervention in increasing condom use among young migrants in China. The intervention also increased protective perceptions and decreased risk perception posited by the theory (i.e., PMT).

To investigate the effectiveness of autogenic relaxation training in a mildly disturbed outpatient population of children and adolescents with mostly internalizing symptoms, and/or some aggressive, impulsive, or attention deficit symptoms. Fifty children and adolescents from southern Germany (mean age 10.2 years; range 6-15 years; mostly intact middle class family background) participated in a group intervention program. Fifteen patients were randomly assigned to a waiting-list control group. Behavior symptoms (Child Behavior Checklist), psychosomatic complaints (Giessen Complaint List), and level of stress were assessed before and after the intervention or after the waiting phase. Individual goal attainment was evaluated at the end of the intervention and in a 3-month follow-up. The parent report on CBCL reflected reduced symptoms compared with control. The child report indicated reduced stress and psychosomatic complaints both in the intervention and control group, and no significant group x time interaction effects occurred on these scales. Effect sizes of 0.49 in the CBCL and 0.36 in the complaint list indicated clinically relevant effects of the intervention compared with the control group. At the end of the intervention, 56% of the children and 55% of the parents reported partial goal attainment, 38% of the children and 30% of the parents reported complete goal attainment; 71% of the parents confirmed partial goal attainment 3 months postintervention. Autogenic relaxation training is an effective broadband method for children and adolescents.

In this study we aimed to identify the role of the body mass index (BMI), wrist index and hand anthropometric measures as risk factors for carpal tunnel syndrome (CTS) in both genders. Based on clinical and electrophysiologic diagnostic criteria, 154 female and 44 male CTS patients, as well as 150 female and 44 male age-matched control subjects, were selected. BMI, wrist index, hand shape index, digit index and hand length/height ratio were compared between the CTS patients and the control subjects for each gender separately. Mean BMI was found to be a significant risk factor for CTS in both genders. The wrist index was found to be higher in female (P < 0.001) and in male (P = 0.034) CTS groups than in the respective control groups. Logistic regression analysis revealed the wrist index to be an independent risk factor in females, but not in males. Shape and digit indices were significantly higher in female CTS patients than in corresponding control subjects, and regression analysis showed the shape and digit indices to be independent risk factors for CTS. In the male CTS group, the shape and digit indices did not significantly differ from their controls. Differences in the hand length/height ratio were not statistically significant in female and male CTS patients compared to their controls and it was not found to be an independent risk factor for CTS. Our study confirmed BMI as an independent risk factor for CTS in both genders. Hand and wrist anthropometrics were found to be independent risk factors for CTS in females, but not in males.

Female doctors in Hungary have worse indicators of physical and mental health compared with other professional women. We aimed to cast light on possible indicators of mental health, workload, and burnout of female physicians. Two time-points (T) were compared, in 2003 (T1 n = 408) and 2013 (T2 n = 2414), based on two nationally representative surveys of female doctors, and comparison made with data from other professional control groups. Independent samples t test or chi-squared test was used both for the two time-point comparison and the comparison between the index and the control groups. The background factors of sleep disorders and burnout were assessed by binary logistic regression analysis. No significant differences in the rates of depressive symptoms and suicidal thoughts and attempts were detected between the 2003 and 2013 cohorts, but the prevalence of sleep disorders increased. The workload increased, and there was less job satisfaction in 2013 than in 2003, coupled to more stressful or difficult work-related situations. The personal accomplishment component of burnout significantly decreased in line with the declining work-related satisfaction. Compared to the professional control groups, the prevalence of depressive symptoms, suicide attempts, and sleep disorders was higher among female physicians at both time-points. The number of workplaces, frequency of work-related stressful situations, and intensive role conflict was associated with sleep disorders and decreased personal accomplishment. In comparison with the other professional groups, female doctors had worse mental health indicators with regard to depression, suicidal ideas, and sleep disorders both in 2003 and 2013 while within professional strata the changes seemed to be less. Increasing workload had a clear impact on sleep disorders and the personal accomplishment dimension of burnout.

Chronic Obstructive Pulmonary Disease (COPD) is now the fourth leading cause of death in the world. As COPD medications are associated with high mortality levels, continuous research into the improvement of treatment modalities is being conducted. This study aimed to identify the effects of acupoint-catgut embedment combined with medical treatment on the Body mass index, airflow Obstruction, Dyspnea and Exercise capacity (BODE) index scores of COPD patients. A single-blind randomized controlled trial was conducted on 48 patients; participants were allocated into either the acupoint-catgut embedment with medication group (case group) or the sham acupuncture with medication group (control group). Acupoint-catgut embedment was conducted at the BL13 Feishu, BL43 Gaohuangshu, BL20 Pishu, BL23 Shenshu, and ST40 Fenglong points two times at an interval of 15 days. The BODE index, a primary outcome indicator, was assessed on Day 1 and Day 30. The results showed statistically and clinically significant differences between the two groups—in fact, BODE index scores were reduced by 1.83 points in the case group (p = 0.000). Ultimately, BODE index scores were lower in the intervention group than in the control group, thus indicating a statistically significant and clinically important improvement of COPD-related symptoms. According to these results, acupoint-catgut embedment combined with medical treatment is concluded to be more effective than medical treatment alone in reducing BODE index scores.

Objective To investigate whether pain-related fears are mediators for reducing disability and pain in patients with Complex Regional Pain Syndrome type 1 when treating with Pain Exposure Physical Therapy. Design An explorative secondary analysis of a randomised controlled trial. Participants Fifty-six patients with Complex Regional Pain Syndrome type 1. Interventions The experimental group received Pain Exposure Physical Therapy in a maximum of five treatment sessions; the control group received conventional treatment following the Dutch multidisciplinary guideline. Outcome measures Levels of disability, pain, and pain-related fears (fear-avoidance beliefs, pain catastrophizing, and kinesiophobia) were measured at baseline and after 3, 6, and 9 months follow-up. Results The experimental group had a significantly larger decrease in disability of 7.77 points (95% CI 1.09 to 14.45) and in pain of 1.83 points (95% CI 0.44 to 3.23) over nine months than the control group. The potential mediators pain-related fears decreased significantly in both groups, but there were no significant differences between groups, which indicated that there was no mediation. Conclusion The reduction of pain-related fears was comparable in both groups. We found no indication that pain-related fears mediate the larger reduction of disability and pain in patients with Complex Regional Pain Syndrome type 1 treated with Pain Exposure Physical Therapy compared to conventional treatment.

The present study examined the effectiveness of a training method to enhance balance in people with PD, which could potentially reduce their risk for falls. Specifically, we investigated whether the benefits of the self-controlled use of a physical assistance device for the learning of a balance task, found previously in healthy adults, would generalize to adults with PD. Twenty-eight individuals with PD were randomly assigned to one of two groups, a self-control and a yoked (control) group. The task required participants to stand on a balance platform (stabilometer), trying to keep the platform as close to horizontal as possible during each 30-s trial. In the self-control group, participants had a choice, on each of 10 practice trials, to use or not to use a balance pole. Participants in the yoked group received the same balance pole on the schedule used by their counterparts in the self-control group, but did not have a choice. Learning was assessed one day later by a retention test. The self-control group demonstrated more effective learning of the task than the yoked group. Questionnaire results indicated that self-control participants were more motivated to learn the task, were less nervous, and less concerned about their body movements relative to yoked participants. Possible reasons for the learning benefits of self-controlled practice, including a basic psychological need for autonomy, are discussed. Copyright © 2011 Elsevier B.V. All rights reserved.

Idiopathic hypogonadotrophic hypogonadism (IHH) with an olfactory deficit is defined as Kallmann syndrome (KS) and is distinct from normosmic IHH. Because olfactory perception not only consists of orthonasally gained impressions but also involves retronasal olfactory function, in this study we decided to comprehensively evaluate both retronasal and orthonasal olfaction in patients with IHH. This case-control study included 31 controls and 45 IHH patients. All participants whose olfactory and taste functions were evaluated with orthonasal olfaction (discrimination, identification and threshold), retronasal olfaction, taste function and olfactory bulb volume (OBV) measurement. The patients were separated into three groups according to orthonasal olfaction: anosmic IHH (aIHH), hyposmic IHH (hIHH) and normosmic IHH (nIHH). Discrimination, identification and threshold scores of patients with KS were significantly lower than controls. Threshold scores of patients with nIHH were significantly lower than those of controls, but discrimination and identification scores were not significantly different. Retronasal olfaction was reduced only in the aIHH group compared to controls. Identification of bitter, sweet, sour, and salty tastes was not significantly different when compared between the anosmic, hyposmic, and normosmic IHH groups and controls. OBV was lower bilaterally in all patient groups when compared with controls. The OBV of both sides was found to be significantly correlated with TDI scores in IHH patients. 1) There were no significant differences in gustatory function between controls and IHH patients; 2) retronasal olfaction was reduced only in anosmic patients but not in orthonasally hyposmic participants, possibly indicating presence of effective compensatory mechanisms; 3) olfactory bulb volumes were highly correlated with olfaction scores in the HH group. The current results indicate a continuum from anosmia to normosmia in IHH patients. Copyright © 2017 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Web-based treatment programs are attractive in primary care because of their ability to reach numerous individuals at low cost. Our aim of this meta-analysis is to systematically review the weight loss or maintenance effect of the Internet component in obesity treatment programs. MEDLINE and EMBASE literature searches were conducted to identify studies investigating the effect of Web-based individualized advice on lifestyle modification on weight loss. Randomized controlled trials that consisted of a Web-user experimental and non-Web user control group were included. Weight changes in the experimental group in comparison with the control group were pooled with a random-effects model. A total of 23 studies comprising 8697 participants were included. Overall, using the Internet had a modest but significant additional weight-loss effect compared with non-Web user control groups (-0.68 kg, P=0.03). In comparison with the control group, stratified analysis indicated that using the Internet as an adjunct to obesity care was effective (-1.00 kg, P<0.001), but that using it as a substitute for face-to-face support was unfavorable (+1.27 kg, P=0.01). An additional effect on weight control was observed when the aim of using the Internet was initial weight loss (-1.01 kg; P=0.03), but was not observed when the aim was weight maintenance (+0.68 kg; P=0.26). The relative effect was diminished with longer educational periods (P-trend=0.04) and was insignificant (-0.20 kg; P=0.75) in studies with educational periods of 12 months or more. The current meta-analysis indicates that the Internet component in obesity treatment programs has a modest effect on weight control. However, the effect was inconsistent, largely depending on the type of usage of the Internet or the period of its use.

The aim of the study was to evaluate the effect of micronized β-1.3/1.6-D-glucan (BG) derived from the oyster mushroom Pleurotus ostreatus Hiratake and tetracycline antibiotic oxytetracycline (OTC) on biometrical, haematological, biochemical, and immunological indices, and histopathological changes in tissues of one- to two-year-old common carp (Cyprinus carpio L.). The fish tested were divided into five experimental groups and one control. Carp in the control group were fed commercial carp feed pellets. Fish in the five experimental groups were fed the same pellets supplemented with either OTC, a combination of OTC and BG, or BG as follows: 75 mg oxytetracycline kg(-1) bw (OTC group), 75 mg oxytetracycline kg(-1) bw and 0.5% β-glucan (OTC + 0.5% BG group), 75 mg oxytetracycline kg(-1) bw and 2.0% β-glucan (OTC + 2.0% BG group), 0.5% β-glucan (0.5% BG group), and 2.0% β-glucan (2.0% BG group). OTC- and BG-supplemented diets and the control diet were administered to experimental and control carp for 50 days (i.e. samplings 1-3, the exposure period); for the following 14 days, fish were fed only control feed pellets with no OTC or BG supplementation (i.e. sampling 4, the recovery period). Blood and tissue samples were collected both during, and at the end of the study. No significant changes in biometrical indices (i.e. total length, standard length, total weight, hepatosomatic and spleen somatic index, and Fulton's condition factor) were found in experimental carp compared to control in any sampling. In haematological indices, significant changes were found only in sampling 2, in which shifts in PCV (P < 0.01), Hb (P < 0.01), and WBC (P < 0.01), and in the counts of lymphocytes (P < 0.01), monocytes (P < 0.01), and neutrophil granulocytes-segments (P < 0.05) were revealed. As for biochemical profiling, plasma concentrations of glucose, albumins, cholesterol, natrium, and chlorides (all P < 0.01), and total proteins, lactate, phosphorus, and potassium (all P < 0.05) as well as the catalytic activity of ALP (P < 0.05) were altered in common carp. A significant change in induced (opsonizedzymosan particles, OZP) chemiluminescence (P < 0.05) in sampling 3 and no shifts in serum immunoglobulins concentration were found in the immunological analysis. Histopathological examination of skin, gills, liver, spleen, and cranial and caudal kidneys revealed no obvious specific changes in any tissue analysed. The use of β-glucans in clinically healthy aquaculture remains an issue. Nevertheless, their use in breeding endangered by stress stimuli, infectious disease, or adverse environmental factors is defensible. Copyright © 2013 Elsevier Ltd. All rights reserved.

To study the effect of leptin on the expression of calcium-activated neutral protease 1 (calpain-1) and B cell lymphoma-2 (Bcl-2) and apoptosis in the myocardial tissue of neonatal rats after asphyxia. A total of 48 neonatal rats were randomly and equally divided into normal control group, asphyxia group, leptin treatment groups, and calpain-1 inhibitor (CAI-1) group. The neonatal rat model of asphyxia under normal atmospheric condition was established in all groups except the control group. For the leptin treatment groups, rats received 20, 80, and 160 μg/kg leptin by intraperitoneal injection immediately after model establishment, respectively. For the CAI-1 group, rats received 10 mg/kg CAI-1 by intraperitoneal injection immediately after model establishment. For all the groups, the myocardial tissue was collected at 2 hours after model establishment. Immunohistochemistry was used to measure the expression of calpain-1 and Bcl-2. The TUNEL method was used to evaluate apoptosis of myocardial cells. The expression of calpain-1 and Bcl-2 and apoptosis index (AI) were significantly higher in the asphyxia group than in the normal control group (P˂0.05). The leptin treatment groups and the CAI-1 group had significantly lower expression of calpain-1, significantly lower AI, and significantly higher expression of Bcl-2 than the asphyxia group (P˂0.05). The CAI-1 group had the largest changes in all the indices compared with the asphyxia group. However, there were no significant differences in all indices between the 160 μg/kg leptin treatment group and the CAI-1 group. After asphyxia, the expression of calpain-1 was positively correlated with AI, while the expression of Bcl-2 was negatively correlated with AI and the expression of calpain-1 (P˂0.05). Leptin reduces apoptosis of myocardial cells in asphyxiated neonatal rats by the inhibition of calpain-1 activation and upregulation of Bcl-2 expression.

This study was conducted to examine the effect of a healthy nails program on nail-biting in Turkish schoolchildren. This quasi-experimental study was of pretest-posttest control group design. A total of 50 students of a primary school formed the intervention group, while 53 students from the same school formed the control group. Data were collected with a demographic form, a nail-biting follow-up form, and photographs of the fingernails. It was found that 68.9% of students were biting seven or more of their nails; 46.6% had damaged nail beds. In the intervention group, the rate of the children who were not biting their nails (baseline = 0%, 4th week = 56.0%, 8th week = 64.0%) increased significantly compared to the control group (baseline = 0%, 4th week = 15.1%, 8th week = 18.9%). Outcomes indicate the efficacy of the healthy nails program in reducing the nail-biting problem in schoolchildren.

The aim of this study was to investigate the oral health status of women with high-risk pregnancies. A case-control study of 142 pregnant women was conducted. The case group included 81 pregnant women with high-risk pregnancies, while 61 women with normal pregnancies served as controls. The following variables were recorded for each woman: age, general health status, DMF, CPITN, and PBI index, amounts of Streptococcus mutans in the saliva and dental treatment needs. The Mann-Whitney test, Kruskal-Wallis test, t-test and chi-squared test were used for statistical analyses. Statistically significant differences were detected between the PBI indices and dental treatment needs of the two groups. Out of the entire study cohort, 77% of the women in the case group and 52% of the women in the control group required dental treatment. In this study, women with complications during pregnancy had severe gingivitis and needed more frequent dental treatment than those in the control group.

A sample of 44 male Type A insurance representatives, selected by means of the Videotaped Structured Interview, were randomly assigned to a treatment (n = 22) and a delayed treatment control group (n = 22). The treatment group participated in 9 weekly sessions of group Rational-Emotive Behavior Therapy and were followed up after 10 weeks. After the control period, the delayed treatment control group received the same treatment program. Repeated measurements were obtained by means of the Videotaped Structured Interview, Jenkins Activity Survey, Cook-Medley Hostility Scale, and Type A Cognitive Questionnaire. Self and spouse/friend ratings of Type A behavior were obtained by means of the Bortner Rating Scale. Analysis indicated that, compared to the control condition, the therapy significantly reduced the intensity of Type A behavior and its time urgency component. These improvements were maintained at follow-up and were accompanied by self-reports of significant positive changes in Type A behavior and irrational beliefs.

To evaluate the effect of an educational intervention among primary care physicians on several indicators of good clinical practice in diabetes care. Two groups of physicians were randomly assigned to the intervention or control group (IG and CG). Every physician randomly selected two samples of patients from all type 2 diabetic patients aged 40 years and above and diagnosed more than a year ago. Baseline and final information were collected cross-sectionally 12 months apart, in two independent samples of 30 patients per physician. The educational intervention comprised: distribution of educational materials and physicians' specific bench-marking information, an on-line course and three on-site educational workshops on diabetes. External observers collected information directly from the physicians and from the medical records of the patients on personal and family history of disease and on the evolution and treatment of their disease. Baseline information was collected retrospectively in the control group. Intervention group comprised 53 physicians who included a total of 3018 patients in the baseline and final evaluations. CG comprised 50 physicians who included 2868 patients in the same evaluations. Measurement of micro-albuminuria in the last 12 months (OR = 1.6, 95% CI: 1.1-2.4) and foot examination in the last year (OR = 2.0, 95% CI: 1.1-3.6) were the indicators for which greater improvement was found in the IG. No other indicator considered showed statistically significant improvement between groups. The identification of indicators with very low level of compliance and the implementation of a simple intervention in physicians to correct them is effective in improving the quality of care of diabetic patients. © 2013 John Wiley & Sons Ltd.

Pathological tooth wear is often associated with bruxism, which appears in turn to be influenced by psychosocial factors. This study investigated putative relationships between psychosocial factors (total and average perceived stress, state and trait anxiety) and tooth wear, comparing 45 patients exhibiting tooth wear with a significant component of attrition to 45 controls. Groups were matched for gender and age. Subjects completed the Modified and Perceived Stress Scale and the State-Trait Anxiety Inventory. A between-groups multivariate analysis of variance indicated that the two groups did not differ significantly on the combined psychosocial factors, F(4,85) = 1.16, P > 0.05. However, a univariate F-test showed that tooth-wear patients presented significantly more trait anxiety than controls, F(1,88) = 4.15, P < 0.05. Further research is indicated to clarify the importance of trait anxiety and other psychosocial factors in the progression of tooth wear with a significant component of attrition.

Simulated clinical conditions were used to test the effect of sterilization on rubber-dam clamp stiffness and dimension. Sixty Hygienic and Ivory W7 clamps were either steam or dry heat sterilized and compared to controls. Stiffness and dimensional change between Ivory clamp groups was significant (p<.0001); the sterilized clamps showed less change than the controls. Hygienic groups showed a significant different between the control and dry heat groups (p<.05); the sterilized clamps showed less change than the controls. The change in stiffness and interjaw width for all Ivory clamps compared to all Hygienic clamps was significant (p<.0001). The Hygienic clamps changes less than the Ivory clamps. The results indicate that steam and dry heat sterilization do not affect retention of rubber-dam clamps.

This study explored the effects of Cocos nucifera L. water (CW) on the hypothalamo-pituitary-gonadal axis (HPG) and fertility in Wistar rats. Adult male and female Wistar rats were treated orally as follows; Study 1: Group 1: control (distilled water), group 2: 20 ml/kg corn oil (danazol vehicle), group 3: 20 ml/kg CW, group 4: 40 ml/kg CW, group 5: danazol, group 6: danazol + 20 ml/kg CW and group 7: danazol + 40 ml/kg CW. 200 mg/ kg danazol was administered. Serum levels of LH, FSH, estradiol and testosterone; gonadal weights and sperm indices were assessed. Study 2: Group 1: control (distilled water), group 2: 20 ml/kg CW, group 3: 40 ml/kg CW for 6 and 2 weeks prior to mating in male and female rats respectively. Significant (p < 0.05) increases in estradiol concentration were observed in groups 3, 4, 6 and 7. Significant reductions in LH, FSH, estradiol and testosterone levels were observed in group 5 which were ameliorated in groups 6 and 7. Males showed significant increases in sperm count and motility in groups 3, 4, 6 and 7, and reductions in these variables along with viability in group 5. CW pre-treatment increased fecundity index and proportion of female pups from dams, while the pups from sires showed higher birth weights. CW acts on the HPG to positively influence reproductive function in both males and females and may aid in maternal preconception sex selection of female offspring.

A total of 135 caregivers-care receiver dyads were randomly divided into an intervention group (n = 66) and a control group (n = 69). One-third of the care receivers were demented, and two-thirds had other diseases. Health centres (publicly funded primary health care systems) in 8 rural and urban communities in southeast Finland. The multicomponent support programme for the caregivers consisted of a 2-week rehabilitation period. The control group received standard care. Continuation of the caregiver and care receiver relationship, care receiver mortality at the 2-year follow-up as well as the health-related quality of life (15D scale) and Zung's depression scale of the caregiver at the 1-year follow-up were evaluated. At the 2-year follow-up, the caregiver-care receiver relationship was terminated for any reason in 11 cases (17%) in the intervention group, and in 25 cases (36%) in the control group. After adjusting, the primary outcome (i.e., termination of care giving for any reason) indicated statistical significance (p = 0.04) with a hazard rate of 1.83 (95% confidence interval 1.03-3.29). With a similar adjustment, the difference in mortality and placement to institutional care between the two groups demonstrated a trend towards statistical significance. The caregivers' health, as related to quality of life and depressive symptoms, remained unchanged in both groups at the 1-year follow-up. These results indicate that a tailored support programme for caregivers may help the caregiver to continue the caregiver-care receiver relationship and delay institutionalization.

Treatment of tendon-bone junction injuries is a challenge because tendon-bone interface often heals poorly and the fibrocartilage zone, which reduces stress concentration, at the interface is not formed. In this study, we used a compound called kartogenin (KGN) with platelet-rich plasma (PRP) to induce the formation of fibrocartilage zone in a rat tendon graft-bone tunnel model. The experimental rats received KGN-PRP or PRP injections in the tendon graft-bone tunnel interface. The control group received saline. After 4, 8 and 12 weeks, Safranin O staining of the tendon graft-bone tunnels revealed abundant proteoglycans in the KGN-PRP group indicating the formation of cartilage-like transition zone. Immunohistochemical and immuno-fluorescence staining revealed collagen types I (Col-I) and II (Col-II) in the newly formed fibrocartilage zone. Both fibrocartilage zone formation and maturation were healing time dependent. In contrast, the PRP and saline control groups had no cartilage-like tissues and minimal Col-I and Col-II staining. Some gaps were also present in the saline control group. Finally, pull-out strength in the KGN-PRP-treated group at 8 weeks was 1.4-fold higher than the PRP-treated group and 1.6-fold higher than the saline control group. These findings indicate that KGN, with PRP as a carrier, promotes the formation of fibrocartilage zone between the tendon graft and bone interface. Thus, KGN-PRP may be used as a convenient cell-free therapy in clinics to promote fibrocartilage zone formation in rotator calf repair and anterior cruciate ligament reconstruction, thereby enhancing the mechanical strength of the tendon-bone interface and hence the clinical outcome of these procedures.

Fixed orthodontic treatment is frequently associated with increased plaque accumulation leading to gingivitis and white spot lesions (WSLs). This study evaluated the role of text message reminder on oral hygiene of orthodontic patients. A total of 60 patients under fixed orthodontic treatment were randomly divided into two equal groups as control group and study (text message) group. Text message group received reminders about oral hygiene, while the control group did not receive any messages. Oral hygiene of both the groups was evaluated at baseline, 2, and 3 months using plaque indices (PIs) along with WSL status. Data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) statistical software, version 19, with chi-square test and t-test. At the baseline, plaque score was higher in the study group over control group (p > 0.038), whereas it was decreased after 3 months in the test group (p > 0.001). For WSL, there was no significant difference at baseline, but it was significantly lower in study group (p > 0.003). Oral hygiene status improved with text message reminder.

To investigate the effects of electromagnetic radiation on the physiological indices and immune function of operators. The general conditions and electromagnetic radiation awareness rate of 205 operators under electromagnetic radiation were evaluated using a self-designed questionnaire. Physical examination, electrocardiography, and routine urine test were performed in these operators. Peripheral blood was collected from the operators under electromagnetic radiation for blood cell counting and biochemical testing, and their peripheral blood lymphocytes were cultured for determination of chromosomal aberrant frequency and micronucleus frequency. The data from these operators (exposure group) were compared with those of 95 ordinary individuals (control group). The chief complaint of giddiness, tiredness, dizziness, and amnesia showed significant differences between the exposure group and control group (P < 0.01), and the difference in headache became larger with an increase in working years. The awareness rate of electromagnetic radiation damage was significantly higher in the exposure group than in the control group. The difference in bradycardia was significant between the two groups (P <0.01), and the incidence was higher with longer working years. Significant differences between the two groups were also found in the numbers of individuals with elevated alanine aminotransferase, total bilirubin, and direct bilirubin (P < 0.01), populations with increased lymphocyte ratio and decreased neutrophil ratio (P < 0.01), populations with positive occult blood, urobilinogen, and bilirubin tests, and the number of individuals with increased micronucleus frequency of cultured peripheral blood lymphocytes (P < 0.01). In addition, the exposure group had significantly increased complement C3 and C4 (P < 0.01), significantly increased IgG (P < 0.05), and significantly decreased IgM (P < 0.01), as compared with the control group. Electromagnetic radiation may lead to the changes in physiological indices, genetic effects, and immune function and affect the health and immune function in operators. The adverse effects are increased as the working years increase. So it is important to strengthen occupational protection of operators under electromagnetic radiation.

We previously performed a preliminary 6-month controlled trial to examine the effect of a disease management education program on prolongation of the time to renal replacement therapy (RRT) and/or avoidance of RRT for patients with diabetic nephropathy. However, its duration was too short to follow the changes of renal function, so we performed the present study for 24 months. This was a two-group comparative study. The intervention group received self-management education from disease management nurses and was supported by the nurses in cooperation with their primary physicians for 12 months. Then this group was followed for a further 12 months. The control group received standard care and was followed for 24 months. Of the 31 subjects enrolled in each group, 26 subjects in the intervention group and 27 subjects in the control group were analyzed after excluding drop-outs. During the study period, 0 and 2 subjects in the intervention and the control group started RRT, respectively. In the intervention group, renal function was maintained, while significant worsening was observed in the control group. Hemoglobin A1c (HbA1c) improved in the intervention group, but became significantly worse in the control group. In the intervention group, all process indicators of behavior modification increased significantly after intervention. A well-designed disease management program might be useful for maintaining renal function and improving HbA1c in patients with diabetic nephropathy. It is considered that modification of patient behavior contributed to these results.

The study aims to explore the effect of positive psychological intervention (fun activities combined with positive mental health education) on the well-being, 2-week illness prevalence, and salivary immunoglobulin A of empty nesters. Ninety-two empty nesters were divided into intervention ( n = 49) and control ( n = 43) groups. The empty nesters in the intervention group performed the intervention in addition to routine community activities. The intervention group scored significantly higher on well-being ( p< .05) compared with the control group after intervention. A week after intervention, salivary immunoglobulin A of the intervention group ( p< .05) was higher than that before intervention. Meanwhile, the difference in salivary immunoglobulin A in the control group before and after intervention was not statistically significant. 2-week illness prevalence in both groups did not exhibit a significant difference ( p> .05). Results indicate that positive psychological intervention can effectively increase the well-being and salivary immunoglobulin A of empty nesters and improve their physical and mental health.

Progesterone is a sex hormone and its receptors are expressed throughout the hippocampus. This study was aimed at evaluating the effects of different doses of progesterone on memory. Male rats were arbitrarily assigned to nine groups, namely Group I: control, Group II: control-cannula, Group III received 0.5 μl of saline by cannula, Groups IV , V, VI, VII and VIII received progesterone in doses of 0.5, 1, 1.5, 2, and 3 μg/ 0.5 μl by cannula, respectively. Group IX received 0.5 μl almond oil by cannula. Memory performance was tested in form of passive avoidance task. Our results indicated that progesterone at doses of 1.5 and 2 µg (p < 0.05) significantly increased the memory performance while at a dose of 3 µg (p < 0.05), it significantly decreased memory as compared to the control group. The current study revealed that the influence of progesterone on memory is related to its dose (Fig. 1, Ref. 25).

The purpose of this study was to examine the effectiveness of the hemostatic agent BleedArrest compared to control. This was a prospective, experimental design employing an established porcine model of uncontrolled hemorrhage. The minimum number of animals (n=10 per group) was used to obtain a statistically valid result. There were no statistically significant differences between the groups (P>.05) indicating that the groups were equivalent on the following parameters: activating clotting time, the subject weights, core body temperatures, amount of one minute hemorrhage, arterial blood pressures, and the amount and percentage of total blood volume. There were significant differences in the amount of hemorrhage (P=.033) between the BleedArrest (mean=72, SD±72 mL) and control (mean=317.30, SD±112.02 mL). BleedArrest is statistically and clinically superior at controlling hemorrhage compared to the standard pressure dressing control group. In conclusion, BleedArrest is an effective hemostatic agent for use in civilian and military trauma management.

Cell-matrix interactions have critical roles in regeneration, development and disease. The work presented here demonstrates that encapsulated human mesenchymal stem cells (hMSCs) can be induced to differentiate down osteogenic and adipogenic pathways by controlling their three-dimensional environment using tethered small-molecule chemical functional groups. Hydrogels were formed using sufficiently low concentrations of tether molecules to maintain constant physical characteristics, encapsulation of hMSCs in three dimensions prevented changes in cell morphology, and hMSCs were shown to differentiate in normal growth media, indicating that the small-molecule functional groups induced differentiation. To our knowledge, this is the first example where synthetic matrices are shown to control induction of multiple hMSC lineages purely through interactions with small-molecule chemical functional groups tethered to the hydrogel material. Strategies using simple chemistry to control complex biological processes would be particularly powerful as they could make production of therapeutic materials simpler, cheaper and more easily controlled.

A randomized, controlled intervention trial of two household-scale drinking water filters was conducted in a rural village in Cambodia. After collecting four weeks of baseline data on household water quality, diarrheal disease, and other data related to water use and handling practices, households were randomly assigned to one of three groups of 60 households: those receiving a ceramic water purifier (CWP), those receiving a second filter employing an iron-rich ceramic (CWP-Fe), and a control group receiving no intervention. Households were followed for 18 weeks post-baseline with biweekly follow-up. Households using either filter reported significantly less diarrheal disease during the study compared with a control group of households without filters as indicated by longitudinal prevalence ratios CWP: 0.51 (95% confidence interval [CI]: 0.41-0.63); CWP-Fe: 0.58 (95% CI: 0.47-0.71), an effect that was observed in all age groups and both sexes after controlling for clustering within households and within individuals over time.

To assess healing outcomes in venous leg ulcers (VLUs) treated with a combination of collagen, oxidized regenerated cellulose, and silver in conjunction with standard of care (SOC; intervention group) compared with SOC alone (control group). Standard of care included ADAPTIC nonadhering dressing (Acelity, San Antonio, Texas) and compression. Randomized controlled trial that followed patients in 3 US facilities for 12 weeks or until complete healing. Forty-nine patients with VLUs were randomized to either the intervention group (n = 22) or the control group (n = 27). Wound healing over 12 weeks. Intent-to-treat analysis showed a mean percentage wound area reduction at 12 weeks of 85.6% (SD, 28.6%) for the intervention group and 72.5% (SD, 77.8%) for the control group. There was a higher healing rate in the intervention group compared with patients who received SOC only at both week 4 (23% vs 11%) and week 12 (64% vs 59%). There were no adverse events related to the study therapy. Although the results were not significant, there was a trend toward faster healing in the intervention group. The results of this study indicate that collagen/oxidized regenerated cellulose/silver is a suitable and safe adjunctive intervention for use with SOC to manage VLUs.

Physical symptoms (e.g., vomiting) and psychological symptoms (stress, anxiety, and depression) during pregnancy are common. Various strategies such as hypnosis are available to reduce these symptoms. The objective of the authors in this study is to investigate the impact of a hypnosis intervention in reducing physical and psychological symptoms during pregnancy. A pre-test/post-test quasi-experimental design was employed in this study. The hypnosis intervention was given to the experimental group participants at weeks 16 (baseline), 20 (time point 1), 28 (time point 2), and 36 (time point 3) of their pregnancy. Participants in the control group received only the traditional antenatal care. Participants from both groups completed the Depression Anxiety Stress Scale-21 (DASS-21) and a Pregnancy Symptoms Checklist at weeks 16, 20, 28 and 36 of pregnancy. Results indicated that stress and anxiety symptoms were significantly reduced for the experimental group, but not for the control group. Although mean differences for the depressive symptoms were not significant, the experimental group had lower symptoms at time point 3. The physical symptoms' results showed significant group differences at time point 3, indicating a reduction in the experience of physical symptoms for the experimental group participants. Our study showed that hypnosis intervention during pregnancy aided in reducing physical and psychological symptoms during pregnancy.

To evaluate the effects of baby massage on transcutaneous bilirubin levels and stool frequency of healthy term newborns. This Pilot study was conducted on 50 healthy newborns in Valiasr Hospital of IKHC. The infants were randomly allocated to two treatment (massage) and control group. The massage group received massage therapy (according to Touch Therapy) for four days from the first day postnatal while the control group received routine care. Main variable studied were transcutaneous bilirubin level (TCB) and stool frequency which were compared in two groups. There were 50 newborns in the study 25 in each group (50%). There was a significant difference in the TCB levels between two groups (p=0.000) with those in the massage group having lower bilirubin levels. As for the stool frequency there was a significant difference in two groups on the first day showing more defecation in the control group (p=0.042) which on the consequent days was not significant and the frequencies were almost similar. Massage group had a lower transcutaneous billirubin levels compared to the control group, thus, these pilot results indicate that massaging the newborns can be accompanied by a lower bilirubin level in the healthy term newborn.

Diastolic dysfunction contributes to the development and progression of heart failure. Conventional echocardiography and tissue Doppler imaging are widely utilised in clinical research providing a number of indices of diastolic function valuable in the diagnosis and prognosis of heart failure patients. The aim of this meta-analysis was to quantify the effect of exercise training on diastolic function in patients with heart failure. Exercise training studies that investigate different indices of diastolic function in patients with heart failure have reported that exercise training improves diastolic function in these patients. We sought to add to the current literature by quantifying, where possible, the effect of exercise training on diastolic function. We conducted database searches (PubMed, EBSCO, EMBASE, and Cochrane Trials Register to 31 July 2016) for exercise based rehabilitation trials in heart failure, using the search terms 'exercise training, diastolic function and diastolic dysfunction'. Data from six studies, with a total of 266 heart failure with reduced ejection fraction (HFrEF) participants, 144 in intervention groups and 122 in control groups, indicated a significant reduction in the ratio of early diastolic transmitral velocity (E) to early diastolic tissue velocity (E') (E/E' ratio) with exercise training, exercise vs. control mean difference (MD) of -2.85 (95% CI -3.66 to -2.04, p < 0.00001). Data from five studies in heart failure with preserved ejection fraction (HFpEF) patients, with a total of 204 participants, 115 in intervention groups and 89 in control groups, also demonstrated a significant improvement in E/E' in exercise vs. control MD of -2.38 (95% CI -3.47 to -1.28, p < 0.0001).

The concentrating ability of the kidney was studied by clearance and micropuncture techniques and tissue slice analyses in normal rats with two intact kidneys (intact controls), normal rats with a solitary kidney (uninephrectomized controls), and uremic rats with a single pyelonephritic kidney. Urinary osmolality after water deprivation for 24 h and administration of antidiuretic hormone was 2,501+/-217 and 2,874+/-392 mosmol/kg H2O in intact and uninephrectomized control rats, respectively, and 929+/-130 mosmol/kg H2O in pyelonephritic rats (P less than 0.001 compared to each control group). Fractional water reabsorption and concentrating ability were significantly decreased in the pyelonephritic group, and, to achieve an equivalent fractional excretion of urea, a greater fractional excretion of water was required in the pyelonephritic rats than in the control rats. Whole animal glomerular filtration rate was 1.57+/-0.19 ml/min and 1.39+/-0.18 ml/min in intact and in uninephrectomized controls, respectively, and 0.30+/-0.07 ml/min in pyelonephritic rats (P less than 0.001 compared to each control group). Single nephron glomerular filtration rate was 35.6+/-3.8 nl/min in intact control rats and was significantly increased (P less than 0.05) in both uninephrectomized (88.0+/-10.8 nl/min) and pyelonephritic rats (71.5+/-14.4 nl/min). In all groups fractional water delivery and fractional sodium delivery were closely comparable at the end of the proximal convoluted tubule and at the beginning of the distal convoluted tubule. In contrast, fractional urea delivery out of the proximal tubule was greater in the intact control group (73+/-8%) than in either the uninephrectomized (52+/-2%) or the pyelonephritic group (53+/-3%) (P less than 0.005). Fractional urea delivery at the early part of the distal tubule increased significantly to 137+/-11% and 93+/-6% of the filtered load in intact control and uninephrectomized control rats, respectively (P less than 0.001 compared to the late proximal values of each group), but failed to increase significantly in pyelonephritic rats (65+/-13%), indicating interruption of the normal recycling of urea in the latter group. Analysis of tissue slices demonstrated a rising corticopapillary gradient for total tissue water solute concentration as well as for tissue water urea concentration in both groups of control rats. In contrast, the pyelonephritic animals exhibited no similar gradients from cortex to papilla. These data indicate that the pyelonephritic kidney fails to recycle urea and accumulate interstitial solute. The latter must inevitably lead to a concentrating defect. Images PMID:993348

The invasive dental procedures usually result in wounds accompanied by physiological bleeding. Even though the bleeding is easily manageable, it is still one of the major concerns of the patients and a reason for their subjective discomfort. Recently, a novel approach with light-emitting diode (LED) was introduced to control the bleeding. This study aims to examine the effectiveness of the irradiation with blue-violet light LEDs on the haemostasis. The study included 40 patients with an indication for tooth extraction, divided into two groups: examination group (n = 30) and a control group (n = 10). The site of the extraction socket in the examination group was irradiated with LED (410 nm) until the bleeding stopped. The patients from the control group were treated by conventional gauze pressure to stop the bleeding (control group). The duration of irradiation and gauze pressure was measured and compared. The statistical analysis was performed with Student T-test. The examination group showed the shorter duration of bleeding compared to the control group for 13.67 seconds and 156 seconds, respectively. The most of the cases in the examination group were irradiated in 10 seconds (70%), followed by irradiation of 20 seconds (23.3%) and 30 seconds (6.6%). In the control group, the average time to stop the bleeding by the conventional method was 156 second. The blue-violet LED light shortens the bleeding time from the extraction socket after tooth extraction and may be a promising method for achieving haemostasis.

Background Acute postoperative pain delays recovery and increases morbidity and mortality. Traditional administration of postoperative analgesics by nurses is often inefficient. The present study evaluated the safety, efficacy, and usability of a novel, patient-controlled analgesic dispenser, the PCoA Acute. Methods A controlled pilot study was conducted at three medical centers. Patients scheduled for elective surgery were enrolled into two groups, both taking oral analgesics: a control group (n = 43), opioids dispensed by nurses, and a test group (n = 27), opioids dispensed via the PCoA Acute. Pill intake data were recorded. Pain ratings at rest and during movement were surveyed. Results No severe adverse events were recorded. Average pill intake time was reduced from 8 : 58 minutes in the control group to 1 : 17 minutes in the test group (P value < 0.05). The test group took 67% more pills than the control group, indicating enhanced compliance. Pain scores were significantly lower for patients in the test group (P value < 0.05). Over 90% of PCoA Acute users were satisfied with its use. Conclusions The study confirmed that PCoA Acute is safe and effective. It is well accepted by patients and medical staff. Its use can optimize pain medication administration. PMID:29093632

Effects of transplantation of adipose-derived nucleated cell fractions (ADNCs) on sciatic nerve regeneration were studied. A 10-mm sciatic nerve defect was bridged using artery graft filled with ADNCs. In control group, artery graft was filled with saline alone. Regenerated nerve fibres were studied for 12 weeks. In sham-operated group, sciatic nerve was only exposed and manipulated. Behavioural and functional studies confirmed faster recovery of regenerated axons in ADNCs transplanted animals than in control group (P<0.05). At the end of study period, animals in ADNCs transplanted group achieved a sciatic functional index (SFI) value of -31.6 ± -3.14, whereas in control group a value of -42.5 ± -3.7 was found. Gastrocnemius muscle mass in ADNCs transplanted animals was found to be significantly higher than that in control group (P=0.001). Morphometric indices of regenerated fibres showed the number and diameter of myelinated fibres to be significantly higher in ADNCs transplanted animals than in control group (P=0.001). On immunohistochemistry, there was more positive staining of S100 in the ADNCs transplanted animals than in control group. ADNCs transplantation into an artery graft could be considered a readily accessible technique that improves functional recovery of sciatic nerve.

This study was designed to compare lipid peroxidation and antioxidant enzymes activity in Type 2 diabetes patients with good or weak glycemic control. In this case-control study, 62 Type 2 diabetic patients with glycated hemoglobin (HbA1c) between 6 and 8 were enrolled as the controlled group and 55 patients with HbA1c > 8 were selected as an uncontrolled group. Patients were all referred to Iranian Diabetes Association in Tehran, Iran, from 2010 onward. Groups were chosen by convenience sampling and were matched based on age, sex and duration of disease. Demographic questionnaire, two 24-hour food recall, HbA1c, insulin, malondialdehyde (MDA), superoxide dismutase (SOD), and catalase were measured in blood samples. Data were analyzed by Food Processor II and SPSS software. A mean daily consumption of energy, carbohydrate, protein, and fat was not significantly different between two groups. MDA in the uncontrolled group was significantly higher than controlled group (2.03 ± 0.88 vs. 1.65 ± 1.01 nmol/ml; P = 0.030). A mean SOD was slightly higher in the uncontrolled group comparing to the control group (843.3 ± 101.9 vs. 828.0 ± 127.3 U/g Hb; P = 0.400). These data suggest that MDA as a lipid peroxidation indicator is higher in uncontrolled diabetes probably due to chronic high blood sugar followed by higher oxidative stress.

This study aimed to estimate the effects of a health mentoring program on fasting blood sugar, total cholesterol, triglyceride, physical activity, self care behavior and social support changes among community-dwelling vulnerable elderly individuals with diabetes. A non-equivalent control group pre-post-test design was used. Participants were 70 community-dwelling vulnerable elderly individuals with diabetes. They were assigned to the experimental (n=30) or comparative (n=30) or control group (n=28). The experimental group participated in the health mentoring program, while the comparative group participated in health education program, the control group did not participate in any program. Data analyses involved a chi-square test, Fisher's exact test, a generalized linear model, and the Bonferroni correction, using SPSS 23.0. Compared to the control group, the experimental and comparative groups showed a significant decrease in fasting blood sugar, total cholesterol, and triglyceride. Compared to the comparative and control groups, the experimental group showed significant improvement in self care behavior. However, there were no statistical differences in physical activity or social support among the three groups. These findings indicate that the health mentoring program is an effective intervention for community-dwelling vulnerable elderly individuals with diabetes. This program can be used as an efficient strategy for diabetes self-management within this population. © 2018 Korean Society of Nursing Science.

The aim of this study was to evaluate the association between metabolic control and oral health of adolescents with type 1 diabetes mellitus (DM1). A case-control epidemiologic study was performed on adolescents allocated between 2 groups: DM1 group composed of 51 with DM1, and control group composed of 51 without diabetes. In the DM1 group, metabolic control data were observed (glycosylated hemoglobin (GHb) and capillary glucose), whereby GHb < or =8.0% was considered to indicate good metabolic control (DM1-A) and >8.0% poor metabolic control (DM1-B). Oral mucosal abnormalites, Community Periodontal Index (CPI), and decayed, missing, and filled (DMF) index were documented. Salivary flow was evaluated by means of stimulated saliva collection (SSFR). Glycosylated hemoglobin values of < or =8.0% (DM1-A) were observed in 17 (24%) and >8.0% (DM1-B) in 34 (76%) of the subjects. The average DMF indexes were 1.5 (control) and 3.3 (DM1-group) (P < or = .05). The average CPIs were 0.2 (control), 1.4 (DM1-A), and 2.0 (DM1-B) (P < or = .05). Average SSFRs were 0.997 (DM1-A), 0.903 (DM1-B), and 1.224 (control) mL/min. Oral health of adolescents with DM1 was impaired regardless of metabolic control. Copyright 2010 Mosby, Inc.

This article aimed to evaluate the effect of an educative action on the knowledge of children's relatives about burns at home. Participants were 40 relatives of children under four years of age, equally divided between an intervention and control group. An initial interview was held, the educative action involved a folder about burns and, after one week, another interview took place. The answers were compared using Fisher's statistical test. In the first interview, 60 answers on risk situations were registered in the control group and 62 in the intervention group; in the second, the results increased to 61 and 80, respectively. In the first interview, 90% of the control group and 80% of the intervention group expressed the belief that childhood burns can be avoided; in the second, this indication decreased to 84% and increased to 100%, respectively. This study showed the importance of the advisory folder on burns at home.

The purpose of this study was to investigate the effects of music therapy techniques on the story retelling and speaking skills of English as a Second Language (ESL) middle school students. Thirty-four middle school students of Hispanic heritage, ages 10-12, in high and low-functioning groups participated in the study for 12 weeks. Pretest to posttest data yielded significant differences on the story retelling skills between the experimental and control groups. Chi Square comparisons on English speaking skills also yielded significant results over 3 months of music therapy intervention. A variety of music therapy techniques were used including music and movement, active music listening, group chanting and singing, musical games, rhythmic training, music and sign language, and lyric analysis and rewrite activities as supplemental activities to the ESL goals and objectives. Comparisons of individual subjects' scores indicated that all of the students in the experimental groups scored higher than the control groups on story retelling skills (with the exception of 1 pair of identical scores), regardless of high and low functioning placement. Monthly comparisons of the high and low functioning experimental groups indicated significant improvements in English speaking skills as well.

The chemopreventive effects of curcumin and green tea catechins individually and in combination on 1,2-dimethylhydrazine (DMH)-induced colon carcinogenesis were studied in male Wister rats following 32 weeks of dietary treatment. The incidence, number and size of colorectal cancer were measured. Colorectal aberrant crypt foci (ACF) were analyzed by methylene blue staining. Proliferation indices and apoptotic indices were determined by PCNA immunostaining and TUNEL assay, respectively. The results showed that dietary curcumin, catechins and combination administration significantly inhibited the total number of ACF per rat. The combination treatment displayed the most potent inhibitory effect, while there was no difference of inhibition between curcumin and catechins-treated groups. The incidence of colorectal cancer in the treated groups was significantly lower than that of positive control group. Compared with the positive control group, the proliferation index was significantly decreased and the apoptotic index was significantly increased in all treatment groups, while the effect of the combination was the greatest among the treated groups. Our findings suggest that the combination of curcumin and catechins may produce a synergistic colon cancer-preventative effect that would be more potent than each of the compounds alone.

This study investigated the effects of joyful learning approach on elementary school students’ attitudes toward science. The method used is quasy experiment with the participants were divided into two groups. Thirty three of 4th grade students volunteered as an experimental group, and the other forty two act as a control group. The data was collected by questionnaire that are given before and after the lesson, observation sheet, and interview. The effect of joyful learning on students’ attitude was obtained by determining the n-gain and independent t-test. Observation and interview results were used to triangulate and support the quantitative findings. The data showed that the gain scores of the experimental group students’ attitudes toward science were significantly higher than the gain scores of control group. In addition, the experimental group made significantly greater progress in their cognitive, affective and conative experiences. Interviews and observations indicated that their attitude toward science changed over the intervention. This indicated that joyful learning approach can enhance the elementary school students’ attitudes toward science. According to these findings, it can be concluded that joyful learning approach can be used as an alternative approach to improve student’s attitude toward science.

Learning physics: A comparative analysis between instructional design methods

NASA Astrophysics Data System (ADS)

Mathew, Easow

The purpose of this research was to determine if there were differences in academic performance between students who participated in traditional versus collaborative problem-based learning (PBL) instructional design approaches to physics curricula. This study utilized a quantitative quasi-experimental design methodology to determine the significance of differences in pre- and posttest introductory physics exam performance between students who participated in traditional (i.e., control group) versus collaborative problem solving (PBL) instructional design (i.e., experimental group) approaches to physics curricula over a college semester in 2008. There were 42 student participants (N = 42) enrolled in an introductory physics course at the research site in the Spring 2008 semester who agreed to participate in this study after reading and signing informed consent documents. A total of 22 participants were assigned to the experimental group (n = 22) who participated in a PBL based teaching methodology along with traditional lecture methods. The other 20 students were assigned to the control group (n = 20) who participated in the traditional lecture teaching methodology. Both the courses were taught by experienced professors who have qualifications at the doctoral level. The results indicated statistically significant differences (p < .01) in academic performance between students who participated in traditional (i.e., lower physics posttest scores and lower differences between pre- and posttest scores) versus collaborative (i.e., higher physics posttest scores, and higher differences between pre- and posttest scores) instructional design approaches to physics curricula. Despite some slight differences in control group and experimental group demographic characteristics (gender, ethnicity, and age) there were statistically significant (p = .04) differences between female average academic improvement which was much higher than male average academic improvement (˜63%) in the control group which may indicate that traditional teaching methods are more effective in females, whereas there was no significant difference noted in the experimental group between male and female participants. There was a statistically significant and negative relationship (r = -.61, p = .01) between age and physics pretest scores in the control group. No statistical analyses yielded significantly different average academic performance values in either group as delineated by ethnicity.

To investigate the influence of hair follicle dermal papilla cells (DPCs) on biological features of composite skin. In the test group, xenogeneic acellular dermal matrix was employed as the frame, DPCs were seeded on the subcutaneous side, and epithelial stem cells onto the dermal papilla side of the dermal frame so as to construct a composite skin. In the control group, there was no DPC in the frame. The two kinds of composite skin were employed to cover skin defects on the back of the nude mice. Wound healing was observed 4 weeks after grafting and area was analyzed and contraction rate was calculated. The tissue samples in the grafted area were harvested for HE staining and the state of the composite skin was observed. The stress-strain curve of the sampled skin was measured, so as to calculate the maximal breaking power of the sample. The data were collected and statistically analyzed. HE staining indicated that the epithelial depth was increased (more than 10 layers of cells) in test group, with only 6-7 layers in control group. The skin contraction rate in test group on the 4th week after skin grafting (3.94+/-0.013)% was much lower than that in control group (29.07+/-0.018)% (P<0.05). It was indicated by biomechanical test that the stress-strain curve of the composite skin in the test group was closer to that of normal nude mice skin in comparison to that in control group. The maximal breaking force of the composite skin in test group was (1.835+/-0.035)N (Newton), while that in control group was (1.075+/-0.065)N (P<0.01). Reconstruction of epidermis in composite skin was promoted by dermal DPCs seeded in the dermal matrix frame. As a result, there was less skin contraction in the composite skin with DPCs, so that the biological characteristics of the skin were improved.

To explore articulatory kinematic differences between normal and dysarthric speakers post-traumatic brain injury (TBI) during syllable and sentence productions. A comparison between the control, mild (MTBI) and severe TBI groups for all measured kinematic parameters was carried out using the Kruskal Wallis test. Ten participants with a severe TBI and six post-MTBI formed the experimental group. The control group consisted of 14 age and sex matched non-neurologically impaired speakers. Articulatory kinematic profiles for the three groups were obtained using the Electromagnetic Articulograph (EMA) while repeating sentence and syllable embedded /t/ and /k/ productions at a habitual rate and loudness level. Significant differences between the severe TBI and control group were identified only for the release phase of the /t/ sentence productions wherein an increase in mean maximum acceleration was observed for the severe TBI group. While a simple syllable repetition task at a moderate rate was unable to differentiate the three groups, a complex sentence production task precipitated an increase in mean maximum acceleration which may be indicative of increased articulatory effort and impaired speech motor control even at a convenient rate for the severe group.

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.

The freshwater golden apple snail, Pomacea canaliculata, is one of the world's 100 worst invasive alien species. The snails' wide distribution, high abundance, and sensitivity to environmental pollution make them a potential bioindicator for environmental contamination. In this study, the biochemical status of golden apple snails collected from paddy fields throughout the island of Taiwan was examined. This study found that the biochemical status of apple snails collected from paddy fields differed from that of animals bred and maintained in the laboratory. Furthermore, certain biochemical endpoints of the snails collected from the paddy fields before and after agricultural activities were also different-hemolymphatic vitellogenin protein was induced in male snail after exposure to estrogen-like chemicals, the hepatic monooxygenase (1.97 +/- 0.50 deltaA(650mm) 30 min(-1) mg(-1) protein in control group) and glutathione S transferase (0.02 +/- 0.01 delta A(340mm) 30 min(-1) mg(-1) protein in control group) snails exposed to pesticides, as well as the hepatopancreatic levels of aspartate aminotransferase (450.00 +/- 59.40 U mg(-1) mg(-1) protein in control group) and alanine aminotransferase (233.27 +/- 42.09 U mg(-1) mg(-1) protein in control group) decreased the indicating that xenobiotics destroyed hepatopancreatic. The above findings reveal that apple snail could be used as a practical bioindicator to monitor anthropogenic environmental pollution.

The nature of mental representation of others plays a crucial role in social interactions. Dogs present an ideal model species for the investigation of such mental representations because they develop social ties with both conspecifics and heterospecifics. Former studies found that dogs' preference for larger food quantity could be reversed by humans who indicate the smaller quantity. The question is whether this social bias is restricted to human partners. We suggest that after a short positive social experience, an unfamiliar moving inanimate agent (UMO) can also change dogs' choice between two food quantities. We tested four groups of dogs with different partners: In the (1) Helper UMO and (2) Helper UMO Control groups the partner was an interactive remote control car that helped the dog to obtain an otherwise unreachable food. In the (3) Non-helper UMO and (4) Human partner groups dogs had restricted interaction with the remote control car and the unfamiliar human partners. In the Human partner, Helper UMO and Helper UMO Control groups the partners were able to revert dogs' choice for the small amount by indicating the small one, but the Non-helper UMO was not. We suggest that dogs are able to generalize their wide range of experiences with humans to another type of agent as well, based on the recognition of similarities in simple behavioural patterns.

The aims of the present study were to investigate if there are differences concerning preferred body posture during sleep between 100 patients, 66 women and 34 men, mean age: 49 years (range: 20-85 years) referred to a specialist clinic because of TMD and 100 matched controls from a public dental clinic. The participants were asked to answer a questionnaire with questions about TMD symptoms and neck or shoulder pain. They were also asked about preferred sleeping position as well as about perceived sleep quality. No differences could be found between the two groups in respect of sleeping position. However, significantly more individuals in the TMD group compared to the controls had changed their preferred sleeping position due to their face and/or jaw and/ or neck-shoulder symptoms. Subjects in the TMD group also more frequently stated that they often felt insufficiently rested at awakening and/or felt tired or sleepy in the daytime because of symptoms from face/jaws. A significant number in the control group reported TMD symptoms indicating a latent need for TMD treatment. It is concluded that sleep position seems to have little or no significance for the development or maintenance of TMD symptoms. However, the study indicates that TMD symptoms and associated neck- and shoulder pain affect the quality of sleep.

The global epidemic of diabetes calls for innovative interventions. This study evaluated the effectiveness of the Project Dulce model, with and without wireless technology, on glycemic control and other clinical and self-reported outcomes in patients with poorly controlled type 2 diabetes in Mexico. Adults with type 2 diabetes and a glycated hemoglobin A1c (HbA1c) level of ≥8% were recruited from Family Medical Unit #27 of the Instituto Mexicano del Seguro Social (IMSS) in Tijuana, México, and randomly assigned to one of three groups: Project Dulce-only (PD); Project Dulce technology-enhanced with mobile tools (PD-TE); or IMSS standard of care/control group (CG). Clinical and self-reported outcomes were assessed at baseline, Month 4, and Month 10. Time-by-group interactions and within-group changes were analyzed. HbA1c reductions from baseline to Month 10 were significantly greater in PD-TE (-3.0% [-33 mmol/mol]) and PD (-2.6% [-28.7 mmol/mol]) compared with CG (-1.3% [-14.2 mmol/mol]) (P = 0.009 and 0.001, respectively). PD-TE and PD also exhibited significant improvement in diabetes knowledge when compared with CG (P < 0.05 for both). No statistically significant differences were detected between PD and PD-TE on these indicators (P = 0.54 and 0.86, respectively). Several within-group improvements were observed on other clinical and self-report indicators but did not vary significantly across groups. Project Dulce with and without wireless technology substantially improved glycemic control and diabetes knowledge in high-risk patients with type 2 diabetes in a Mexican family medical unit, suggesting that integrating peer-led education, nurse coordination, and 3G wireless technology is an effective approach for improving diabetes outcomes in high-risk populations.

Today there are more than 2 billion alcohol users and about 1.3 billion tobacco users worldwide. The chronic and heavy use of these two substances is at the heart of numerous diseases and may wreak havoc on the human oral microbiome. This study delves into the changes that alcohol and tobacco may cause on biofilms of the human oral microbiome. To do so, we used swabs to sample the oral biofilm of 22 subjects; including 9 control-individuals with no or very low consumption of alcohol and no consumption of tobacco, 7 who were chronic and heavy users of both substances and 6 active smokers that reported no significant alcohol consumption. DNA was extracted from swabs and the V1 region of the 16S rRNA gene was PCR amplified and sequenced using the Ion Torrent PGM platform, generating 3.7 million high quality reads. DNA sequences were clustered and OTUs were assigned using the ARB SILVA database and Qiime. We found no differences in species diversity and evenness among the groups. However, we found a significant decrease in species richness in only smokers and in smokers/drinkers when compared to controls. We found that Neisseria abundance was significantly decreased in both groups when compared to controls. Smokers had significant increases in Prevotella and Capnocytophaga and reductions in Granulicatella, Staphylococcus, Peptostreptococcus and Gemella when compared to the two other groups. Controls showed higher abundance of Aggregibacter, whilst smokers/drinkers had lower abundances of Fusobacteria. Samples from only smokers clustered closer together than to controls and smokers/drinkers, and also had a significant reduction in inter-group dissimilarity distances, indicating a more homogenous group than controls. Our results indicate that the continued use of tobacco or alcohol plus tobacco significantly reduces bacterial richness, which apparently leads to a reduction in inter-group variability, turning the respective biofilms into a more homogenous microenvironment in terms of bacterial community composition, with possible consequences for human oral diseases.

The purpose of this study was to document the design, classroom implementation, and effectiveness of interactive online units to enhance science learning over 3 years among students with learning disabilities, English learners, and general education students. Results of a randomised controlled trial with 2,303 middle school students and 71 teachers across 13 schools in two states indicated that online units effectively deepened science knowledge across all three student groups. Comparing all treatment and control students on pretest-to-posttest improvement on standards-based content-specific assessments, there were statistically significant mean differences (17% improvement treatment vs. 6% control; p < .001); no significant interactions were found between treatment condition and learning disability or English learner status, indicating that these two groups performed similarly to their peers; students with learning disabilities had significantly lower assessment scores overall. Teachers and students were moderately satisfied with the units.

Can Dynamic Visualizations with Variable Control Enhance the Acquisition of Intuitive Knowledge?

NASA Astrophysics Data System (ADS)

Wichmann, Astrid; Timpe, Sebastian

2015-10-01

An important feature of inquiry learning is to take part in science practices including exploring variables and testing hypotheses. Computer-based dynamic visualizations have the potential to open up various exploration possibilities depending on the level of learner control. It is assumed that variable control, e.g., by changing parameters of a variable, leads to deeper processing (Chang and Linn 2013; de Jong and Njoo 1992; Nerdel 2003; Trey and Khan 2008). Variable control may be helpful, in particular, for acquiring intuitive knowledge (Swaak and de Jong 2001). However, it bares the risk of mental exhaustion and thus may have detrimental effects on knowledge acquisition (Sweller 1998). Students ( N = 118) from four chemistry classes followed inquiry cycles using the software Molecular Workbench (Xie and Tinker 2006). Variable control was varied across the conditions (1) No-Manipulation group and (2) Manipulation group. By adding a third condition, (3) Manipulation-Plus group, we tested whether adding an active hypothesis phase prepares students before changing parameters of a variable. As expected, students in the Manipulation group and Manipulation-Plus group performed better concerning intuitive knowledge ( d = 1.14) than students in the No-Manipulation group. On a descriptive level, results indicated higher cognitive effort in the Manipulation group and the Manipulation-Plus group than in the No-Manipulation group. Unexpectedly, students in the Manipulation-Plus group did not benefit from the active hypothesis phase (intuitive knowledge: d = .36). Findings show that students benefit from variable control. Furthermore, findings point toward the direction that variable control evokes desirable difficulties (Bjork and Linn 2006).

To observe the clinical effect and efficacy of Xiaozhi Capsule (XZC), a Chinese medicine preparation for tonifying Gan-Shen, invigorating Pi to dissipate dampness (TGSIPDD) on total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and endothelin (ET) in treating patients with hyperlipidemia. Totally 120 primary hyperlipidemia patients were randomly assigned to the treatment group (80 cases) and the control group (40 cases). Those in the treatment group took XZC, while those in the control group took Xuezhikang Capsule (XZKC). The serum TC, TG, HDL-C, LDL-C, and ET were detected and evaluated after 8 weeks of treatment. In the treatment group TC was reduced by 25.60%, TG by 33.70%, LDL-C by 32.90%, and ET by 11.02%, while HDL-C was elevated by 24.20%. In the control group, TC was reduced by 24.80%, TG by 33.50%, LDL-C by 31.30%, and ET by 12.05%, while HDL-C was elevated by 20.90%. There was statistical difference in the two groups when compared with before treatment (P < 0.01). But there was no statistical difference in the aforesaid indices between the two groups after treatment (P > 0.05). The integrals for main symptoms after treatment obviously decreased in the two groups, showing statistical difference when compared with before treatment in the same group (P < 0.01). But there was no statistical difference in the aforesaid indices between the two groups (P > 0.05). After 8 weeks of treatment, symptoms such as vertigo, heavy sensation of head, palpitation, chest distress, dry mouth and thirsty were obviously improved after treatment. There was statistical difference in the improvement of tinnitus after treatment in the treatment group (P < 0.01). The total effective rate was 86.25% in the treatment group and 82.50% in the control group, showing no statistical difference (P > 0.05). XZC showed certain effects on each blood lipid index and ET of hyperlipidemia patients. It had better improvement of clinical symptoms with reliable efficacy.

This study aims to investigate the efficacy and safety of neutral macroporous resin hemoperfusion in treating maintenance hemodialysis (MHD) patients with refractory uremic pruritus (RUP).Ninety patients were enrolled and were randomly divided into 3 groups: control group, experiment 1 group, and experiment 2 group. Clinical symptom scores of skin itching were recorded before and at 4 and 8 weeks after the treatment. In addition, serum parathyroid hormone (PTH), calcium (Ca), phosphorus (P), and C-reactive protein (CRP) were detected; and the calcium-phosphorus product ([Ca] × [P]) was calculated to compare the curative effect.VSA score, modified Duo pruritus score, and CRP: these indices decreased to some extent at 4 and 8 weeks after treatment in the 2 experiment groups, compared with pretreatment (P < 0.05); and differences among these 3 groups were statistically significant (P < 0.05). PTH, P, and [Ca] × [P]: these indices decreased to some extent at 4 and 8 weeks after treatment in the 2 experiment groups, compared with pretreatment (P < 0.05); and differences between the control and experiment 1 groups, as well as between the control and experiment 2 groups, were statistically significant (P < 0.05). However, the difference between the experiment 1 and experiment 2 groups were not statistically significant (P < 0.05).The effects of HA330 and HA130 resin hemoperfusion apparatus on secondary hyperparathyroidism and the disorder of calcium and phosphorus metabolism are similar. The mechanism may be related to its strong adsorption effect, and its capacity to widely remove inflammatory mediators, immune mediators, and endotoxins.

Abstract This study aims to investigate the efficacy and safety of neutral macroporous resin hemoperfusion in treating maintenance hemodialysis (MHD) patients with refractory uremic pruritus (RUP). Ninety patients were enrolled and were randomly divided into 3 groups: control group, experiment 1 group, and experiment 2 group. Clinical symptom scores of skin itching were recorded before and at 4 and 8 weeks after the treatment. In addition, serum parathyroid hormone (PTH), calcium (Ca2+), phosphorus (P3+), and C-reactive protein (CRP) were detected; and the calcium–phosphorus product ([Ca] × [P]) was calculated to compare the curative effect. VSA score, modified Duo pruritus score, and CRP: these indices decreased to some extent at 4 and 8 weeks after treatment in the 2 experiment groups, compared with pretreatment (P < 0.05); and differences among these 3 groups were statistically significant (P < 0.05). PTH, P3+, and [Ca] × [P]: these indices decreased to some extent at 4 and 8 weeks after treatment in the 2 experiment groups, compared with pretreatment (P < 0.05); and differences between the control and experiment 1 groups, as well as between the control and experiment 2 groups, were statistically significant (P < 0.05). However, the difference between the experiment 1 and experiment 2 groups were not statistically significant (P < 0.05). The effects of HA330 and HA130 resin hemoperfusion apparatus on secondary hyperparathyroidism and the disorder of calcium and phosphorus metabolism are similar. The mechanism may be related to its strong adsorption effect, and its capacity to widely remove inflammatory mediators, immune mediators, and endotoxins. PMID:28328802

A clinical trial, including five East Coast fever (ECF) control strategies (involving tick control and/or immunisation by infection-and-treatment) in five different groups of traditionally managed Sanga cattle, was conducted in Central Province of Zambia over 2.5 years between 1992 and 1995. Two groups were kept under intensive tick control by weekly acaricide treatment by hand spray; (one immunised and one non-immunised), two groups were under no tick control (one immunised and one non-immunised), and a fifth, immunised group was maintained under strategic tick control (18 sprays yr-1). ECF-specific mortality was highest in the non-immunised and non-treated group, while no difference in ECF-specific mortality could be observed between animals treated for ECF by immunisation or by tick control. Acaricide treatment and/or immunisation reduced the risk of clinical ECF by 92%. The results of an artificial challenge experiment at the end of the field trial indicated that about 60% of the animals in the control group had become infected with Theileria parva without showing clinical signs. ECF incidence in non-vaccinated cattle markedly declined six months after immunisation--suggesting that the carrier state induced by immunisation did not lead to a persistent high incidence, and might accelerate the progress to endemicity.

The transtheoretical model was applied to promote behavioural change and test the effects of a group senior elastic band exercise programme on the functional fitness of community older adults in the contemplation and preparation stages of behavioural change. Forming regular exercise habits is challenging for older adults. The transtheoretical model emphasizes using different strategies in various stages to facilitate behavioural changes. Quasi-experimental design with pre-test and post-tests on two groups. Six senior activity centres were randomly assigned to either the experimental or control group. The data were collected during 2011. A total of 199 participants were recruited and 169 participants completed the study (experimental group n = 84, control group n = 85). The elastic band exercises were performed for 40 minutes, three times per week for 6 months. The functional fitness of the participants was evaluated at baseline and at the third and sixth month of the intervention. Statistical analyses included a two-way mixed design analysis of variance, one-way repeated measures analysis of variance and an analysis of covariance. All of the functional fitness indicators had significant changes at post-tests from pre-test in the experimental group. The experimental group had better performances than the control group in all of the functional fitness indicators after three months and 6 months of the senior elastic band exercises. The exercise programme provided older adults with appropriate strategies for maintaining functional fitness, which improved significantly after the participants exercising regularly for 6 months. © 2015 John Wiley & Sons Ltd.

This research study was conducted to establish the influence of familiarization on the information component of movement in a motor task for the assessment of preschool children's motor skills. The sample included 50 children whose mean age was 5.9 years (71.5 months). The experimental group consisted of 27 children who were 5.9 years (71.5 months) old, and the control group consisted of 23 children who were 5.9 years (71.5 months) old. The examinees performed 2 motor tasks, standing long jump (SJ, explosive strength) and standing on 1 leg on a beam "flamingo test" (FT, balance). The experimental group underwent a period of familiarization with the motor task in 3 sessions with 5 trials every 3 days. The results indicate statistically significant differences in the final testing between both groups of examinees; the experimental group mean was 112.73 cm, and the control group mean was 100.62 in the SJ test (p = 0.00), and the experimental group mean was 27.10 seconds and the control group mean was 15.01 seconds in the FT (for balance) (p = 0.00). The results obtained in this research indicate that children significantly improved the results in the motor test of strength and balance, being influenced by familiarization. It was confirmed that it was necessary for preschool children to be familiar with the test and it is not justified to use testing and assessment protocols and standards for adults. Physical educators and coaches, when testing preschool children, should introduce children to tests to obtain the best result.

2015-08-01

This study was conducted to develop and test the effects of a motivational interviewing self-management program for use with elderly patients with diabetes mellitus. A non-equivalent control group pretest-posttest design was used. The participants were 42 elderly diabetic patients (experimental group: 21, control group: 21). The motivational interviewing self-management program for elders with diabetes mellitus developed in this study consisted of a 12-week program in total (8 weeks for group motivational interviewing and education and 4 weeks for individual motivational interviewing on the phone). Data were collected between February 13 and May 3, 2013 and were analyzed using t-test, paired t-test, and repeated measure ANOVA with SPSS/WIN 18.0. For the experimental group, significant improvement was found for self-efficacy, self-care behavior, glycemic control and quality of life (daily life satisfaction, influence of disease) as compared to the control group. The study findings indicate that the motivational interviewing self-management program is effective and can be recommended as a nursing intervention for elderly patients with diabetes mellitus.

To evaluate the efficacy of bicyclol in preventing chemotherapy-induced liver damage. Patients ≥60 years of age with cancer were equally randomized into control (chemotherapy alone) or prophylactic (chemotherapy supplemented with 75 mg bicyclol, oral, daily) groups. Liver function indices were assessed immediately before treatment, during each therapy cycle and following treatment. Of 306 patients enrolled, 300 patiets completed the study (n = 147 and n = 153; prophylactic and control groups, respectively). Incidence of grade I-IV elevation of serum transaminase and/or bilirubin was significantly lower in the prophylactic group (17.1%) compared with the control group (47.1%). Incidence of grade II-IV hepatic injury was also significantly lower in the prophylactic group (0.7%) than in the control group (12.4%). Prophylactic bicyclol (75 mg daily) could significantly reduce the incidence and degree of chemotherapeutic agent-induced liver damage in elderly patients with cancer. Further studies are recommended with larger sample sizes and long-term follow up. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Objective Epilepsy is a chronic neurological disease. Evidence has indicated that epilepsy has an impact on mental and physical health of children. The present study aimed to determine the effectiveness of attribution retraining on health enhancement of epileptic children. Materials & Methods This was an experimental study with a pre-test and a post-test design with a control group. Thirty students with epilepsy (11 female and 19 male students) were selected in convenience from Iranian Epilepsy Association. They were assigned to experimental and control groups and their mothers completed Child Health Questionnaire (CHQ-PF.28) before and after the intervention. The experimental group attended to eleven sessions (each session 45 minutes; twice a week). Subjects were trained by attribution retraining program, but control group was not. Multivariate analysis of covariance (MANCOVA) was used for analyzing the data. Results Health (both psychosocial and physical) of experimental group enhanced significantly after the intervention sessions compared to control group. Conclusion Attribution retraining is an effective intervention to enhance the psychosocial and physical health of epileptic children. PMID:27247584

This pilot study compared weight loss and serum indicators of coronary artery disease (CAD) risk between 2 weight loss (energy-deficit) diets, one controlled for carbohydrate as a percentage of total calories and the other controlled for fat as percentage of total calories. Participants were randomized to 1 of 2 diets and fed on an outpatient basis for 70 days, after which they followed their diets using their own resources for an additional 70 days. Energy deficit for the diets was determined by indirect calorimetry with a 500- to 750-calorie per day adjustment. Weight and CAD risk indicators and serum lipid and C-reactive protein levels were measured at baseline, day 70, and day 140. The study was completed by 16 of 20 participants who were able to comply with the feeding portion of the study as well as with follow-up appointments during the second (self-management) period of the study. Participants lost weight in both diet groups (24.4 lbs, carbohydrate controlled; 18.5 lbs, fat controlled), and serum CAD risk factors decreased in both groups. There were no significant differences in CAD risk factors between diet groups, although there was a trend toward lighter low-density lipoprotein (LDL) size in the carbohydrate-controlled group. During the self-management portion of the study, weight loss stalled or regained from loss during the previous feeding period. The results, although underpowered, are consistent with recent studies in which macronutrient ratio of total calories in diet did not affect degree of weight loss and in which carbohydrate-controlled diets produced a predominance of lighter LDLs.

Using patient-reported outcomes and physiological indicators to test the effects of music intervention and aromatherapy on reducing anxiety for intensive care unit (ICU) patients undergoing mechanical ventilation. Patients with ICU admission duration >24 h were randomly assigned to a Music intervention group (n = 41), Aromatherapy group (n = 47), or Control group (rest only; n = 44). Each patient in the Music group listened to music; each patient in the Aromatherapy group received lavender essential oil massage on his/her back for 5 min; each patient in the Control group wore noise-canceling headphones. Anxiety was measured using the Chinese version of the Stage-Trait Anxiety Inventory (C-STAI) and the Visual Analogue Scale for Anxiety (VAS-A) at baseline, post-test, and 30-min follow-up. Heart rate, breathing rate, and blood pressure were measured every 10 min from baseline to the 30-min follow-up. The Music group had significantly better post-test VAS-A and C-STAI scores, and had lower heart rate and blood pressure than the Control group. The Aromatherapy group had significantly better VAS-A score and lower heart rate than the Control group. The 30-min follow-up showed that both Music and Aromatherapy groups had lower heart rate and blood pressure than the Control group. Music and aromatherapy interventions were both effective for ICU patients. The effects of music intervention were greater than that of aromatherapy; both interventions maintained the effects for at least 30 min.

South Asian people and heart disease: an assessment of the importance of socioeconomic position.

PubMed

Nazroo, J Y

2001-01-01

Higher rates of mortality from ischemic heart disease among South Asian people are well established and appear to be unrelated to socioeconomic position. However, traditional indicators of socioeconomic position may be inadequate when making comparisons across ethnic groups. This study investigates these issues in a British morbidity survey. The Fourth National Survey was a British cross-sectional study conducted from 1993 to 1994. The study used a national representative community sample, consisting of 2867 white respondents, 2001 Indian respondents, and 1776 Pakistani and Bangladeshi respondents. Data on occupational class and standard of living were used to examine the contribution of socioeconomic factors to differences in rates of reported severe chest pain and diagnosed heart disease. White and Indian respondents had similar rates of reported indicators of heart disease, while Pakistani and Bangladeshi respondents had rates that were considerably higher. There was a clear socioeconomic gradient in reported heart disease for each ethnic group, with those who were poorer having higher rates. Controlling for occupational class made little difference to the greater risk of heart disease found in the Pakistani and Bangladeshi group; however, controlling for a more sensitive indicator of socioeconomic position-standard of living-greatly reduced their disproportionate risk. The findings suggest that South Asian people do not share a uniformly greater risk of heart disease. The more economically advantaged South Asian group, Indians, had rates that are similar to those found among white people, while the poorest groups, Pakistanis and Bangladeshis, had rates that are considerably higher. Socioeconomic position predicted risk in each ethnic group and made a key contribution to the higher risk found for Pakistani and Bangladeshi individuals. Other studies may have failed to identify the important contribution of socioeconomic position because the indicators used were too crude.

Malkoc, Ummuhan

The present study explored the effect of animation implementation in learning a chemistry topic. 135 high school students taking chemistry class were selected for this study (quasi-experimental groups = 67 and control groups = 68). Independent samples t-tests were run to compare animation and control groups between and within the schools. The over-arching finding of this research indicated that when science teachers used animations while teaching salt dissolution phenomena, students will benefit the application of animations. In addition, the findings informed the TPACK framework on the idea that visual tools are important in students' understanding of salt dissolution concepts.

To compare the effects of an inspiratory versus and expiratory muscle-training program on voluntary and reflex peak cough flow in patients with Parkinson disease. A randomized controlled study. Home-based training program. In all, 40 participants with diagnosis of Parkinson's disease were initially recruited in the study and randomly allocated to three study groups. Of them, 31 participants completed the study protocol (control group, n = 10; inspiratory training group, n = 11; and expiratory training group, n = 10) Intervention: The inspiratory and expiratory group performed a home-based inspiratory and expiratory muscle-training program, respectively (five sets of five repetitions). Both groups trained six times a week for two months using a progressively increased resistance. The control group performed expiratory muscle training using the same protocol and a fixed resistance. Spirometric indices, maximum inspiratory pressure, maximum expiratory pressure, and peak cough flow during voluntary and reflex cough were assessed before and at two months after training. The magnitude of increase in maximum expiratory pressure ( d = 1.40) and voluntary peak cough flow ( d = 0.89) was greater for the expiratory muscle-training group in comparison to the control group. Reflex peak cough flow had a moderate effect ( d = 0.27) in the expiratory group in comparison to the control group. Slow vital capacity ( d = 0.13) and forced vital capacity ( d = 0.02) had trivial effects in the expiratory versus the control group. Two months of expiratory muscle-training program was more beneficial than inspiratory muscle-training program for improving maximum expiratory pressure and voluntary peak cough flow in patients with Parkinson's disease.

To evaluate the assessment of primary biliary cirrhosis degree by acoustic radiation force impulse imaging (ARFI) and hepatic fibrosis indicators. One hundred and twenty patients who developed liver cirrhosis secondary to primary biliary cirrhosis were selected as the observation group, with the degree of patient liver cirrhosis graded by Child-Pugh (CP) score. Sixty healthy individuals were selected as the control group. The four indicators of hepatic fibrosis were detected in all research objects, including hyaluronic acid (HA), laminin (LN), type III collagen (PC III), and type IV collagen (IV-C). The liver parenchyma hardness value (LS) was then measured by ARFI technique. LS and the four indicators of liver fibrosis (HA, LN, PC III, and IV-C) were observed in different grade CP scores. The diagnostic value of LS and the four indicators of liver fibrosis in determining liver cirrhosis degree with PBC, whether used alone or in combination, were analyzed by receiver operating characteristic (ROC) curve. LS and the four indicators of liver fibrosis within the three classes (A, B, and C) of CP scores in the observation group were higher than in the control group, with C class > B class > A class; the differences were statistically significant (P < 0.01). Although AUC values of LS within the three classes of CP scores were higher than in the four indicators of liver fibrosis, sensitivity and specificity were unstable. The ROC curves of LS combined with the four indicators of liver fibrosis revealed that: AUC and sensitivity in all indicators combined in the A class of CP score were higher than in LS alone, albeit with slightly decreased specificity; AUC and specificity in all indicators combined in the B class of CP score were higher than in LS alone, with unchanged sensitivity; AUC values (0.967), sensitivity (97.4%), and specificity (90%) of all indicators combined in the C class of CP score were higher than in LS alone (0.936, 92.1%, 83.3%). The diagnostic value of PBC cirrhosis degree in liver cirrhosis degree assessment by ARFI combined with the four indicators of serum liver fibrosis is of satisfactory effectiveness and has important clinical application value.

Prospective, controlled study with waiting group (control group, n = 18) and e-learning group (n = 20). The control group got the same reference literature list as the e-learning group. Both groups were assessed twice: The e-learning group before and after the course; the control group was assessed at the same times. increase in knowledge about genetics of epilepsies using questionnaires based on items formulated by experts (internal consistency, Cronbach's alpha = 0.86). Main hypothesis: greater increase of knowledge in the e-learning group compared to control group. assessment of the educational course and learning environment by participants and by tutors/e-moderators. Significant time x group interaction and group effect (ANOVA, each p < 0.01) with regard to knowledge. At baseline, the groups did not differ with respect to knowledge about genetics of epilepsy. In contrast to the control group, the increase of knowledge in the e-learning group was highly significant (p < 0.001). The majority of the participants of the e-learning course was content with their personal learning process (75% agree, 15% strongly agree). Most of them reported a gain in competence in the treatment and counseling of people with epilepsy (38.9% agree, 50% strongly agree). All participants would recommend this course to others and all but one participant are interested in other e-learning courses. The study indicates e-learning courses are an appropriate tool to improve knowledge of physicians in genetics of epilepsy.

Calculus pyonephrosis is difficult to manage. The aim of this study is to explore the value of a patented suctioning sheath assisted minimally invasive percutaneous nephrolithotomy (MPCNL) in the treatment of calculus pyonephrosis. One hundred and eighty two patients with calculus pyonephrosis were randomizely divided into observation group (n = 91) and control group (n = 91). The control group was treated with MPCNL traditionally using peel-away sheath while the observation group was treated with MPCNL using the patented suctioning sheath. All the patients in the observation group underwent one stage surgical treatment, 14 patients in the control group underwent first-stage surgery with the rest of the group underwent one stage surgery. The complication rate was 12.1% in the observation group, significantly lower than the rate in the control group which was 51.6%; One surgery stone clearance in the observation group was 96.7% while it was 73.6% in the control group; operative time in the observation group was (54.5 ± 14.5) min, compared to (70.2 ± 11.7) min in the control group; the bleeding amount in the observation group was (126.4 ± 47.2) ml, compared to (321.6 ± 82.5) ml in the control group; the hospitalization duration for the observation group was (6.4 ± 2.3) days, compared to (10.6 ± 3.7) days in the control group. Comparison of the above indicators, the observation group was better than the control group with significant difference (p < 0.001 each). Minimally invasive percutaneous nephrolithotomy with the aid of the patented suctioning sheath in the treatment of calculus pyonephrosis in one surgery is economic, practical, and warrants clinical promotion. This study was registered with Chinese Clinical Trial Registry on May 18, 2016 (retrospective registration) with a trial registration number of ChiCTR-IOR-16008490 .
