Our aim is to determine the effect of paced eating, exposure to an educational programme that promotes healthy eating habits and allowing the satiety reflex to limit food intake in controlling weight gain in healthy adolescents. Fifty-four healthy individuals consisting of 18 adolescent girls and 36 boys aged 12 ± 2 years were given recommendations for reducing eating rate without changing diet or meal size according to the educational programme 'good manners for a healthy future'. Each participant was provided with a 30-s portable hourglass to pace time between bites. Individuals using and not using the hourglass were placed either into an 'adhering' or a 'non-adhering' group, respectively. Control data were obtained from a similar population. Initially, the adhering group had higher weight compared with the non-adhering group (64.1 ± 13.2 vs. 56.2 ± 11.7 kg). Control group weight was no different from the study group at baseline (56.3 ± 10.3 kg). Weight in the adhering group decreased after the first semester of participation by 2.0 ± 5.7% and after a year by 3.4 ± 4.8%, while the non-adhering group gained weight by 5.8 ± 4.5% and 12.6 ± 8.3%. The control group increased weight after a year by 8.2 ± 6.5%. In total, 18 non-adhering and 14 adhering adolescents completed the study. This 1-year study shows a statistically significant association between rate of food intake and weight control in adherence to an educational programme directed at developing healthy eating habits. The proposed behavioural training may serve as an option for weight control in adolescents. © 2015 The Authors.

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.

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.

This prospective, randomized, controlled trial for parents of overweight and obese 3- to 7-year-olds was performed to assess the feasibility of a program promoting healthy eating and lifestyle by targeting parents as agents of change. The intervention was composed of 6-in-person group sessions and a customized website over 12 months. The control group received customary care. The primary outcome was feasibility of the intervention to promote healthy behavior change measured by attendance. The secondary outcome was effectiveness assessed by attaining reduced body mass index (BMI) z scores, healthy behavior changes and increased parent self-efficacy. Seventy-three child-parent dyads were enrolled; 14 parents never attended any sessions. Participation in follow-up assessments did not meet the hypothesized level. Ultimate BMI z scores did not differ between control and intervention groups. Parenting skills did not improve in the intervention group. This intervention to achieve healthy lifestyle changes in children via their parents as "change agents" was unsuccessful.

OBJECTIVE β-Cells have demonstrated altered proinsulin processing after islet transplantation. We compare β-cell metabolic responses and proinsulin processing in pancreas and islet transplant recipients with respect to healthy control subjects. RESEARCH DESIGN AND METHODS We studied 15 islet and 32 pancreas transplant recipients. Islet subjects were subdivided into insulin-requiring (IR-ISL, n = 6) and insulin-independent (II-ISL, n = 9) groups. Ten healthy subjects served as control subjects. Subjects were administered an intravenous arginine stimulation test, and insulin, C-peptide, total proinsulin, intact proinsulin, and proinsulin fragment levels were determined from serum samples. Acute insulin response (AIR) and proinsulin processing rates were calculated. RESULTS We found that basal insulin and C-peptide levels were higher in the pancreas group than in all other groups. II-ISL patients had basal insulin and C-peptide levels similar to healthy control subjects. The IR-ISL group had significantly lower AIRs than all other groups. Basal processing rates were higher in the pancreas and II-ISL groups than in healthy control subjects and the IR-ISL group. After arginine stimulation, all groups had elevated processing rates, with the exception of the IR-ISL group. CONCLUSIONS Our data suggest that II-ISL transplant recipients can maintain basal metabolic parameters similar to healthy control subjects at the cost of a higher rate of proinsulin processing. IR-ISL transplant recipients, on the other hand, demonstrate both lower insulin response and lower basal rates of proinsulin processing even after arginine stimulation. PMID:24041681

Background and aims Given the similarities in clinical symptoms, Internet gaming disorder (IGD) is thought to be diagnostically similar to Internet-based gambling disorder (ibGD). However, cognitive enhancement and educational use of Internet gaming suggest that the two disorders derive from different neurobiological mechanisms. The goal of this study was to compare subjects with ibGD to those with IGD. Methods Fifteen patients with IGD, 14 patients with ibGD, and 15 healthy control subjects were included in this study. Resting-state functional magnetic resonance imaging data for all participants were acquired using a 3.0 Tesla MRI scanner (Philips, Eindhoven, The Netherlands). Seed-based analyses, the three brain networks of default mode, cognitive control, and reward circuitry, were performed. Results Both IGD and ibGD groups demonstrated decreased functional connectivity (FC) within the default-mode network (DMN) (family-wise error p < .001) compared with healthy control subjects. However, the IGD group demonstrated increased FC within the cognitive network compared with both the ibGD (p < .01) and healthy control groups (p < .01). In contrast, the ibGD group demonstrated increased FC within the reward circuitry compared with both IGD (p < .01) and healthy control subjects (p < .01). Discussion and conclusions The IGD and ibGD groups shared the characteristic of decreased FC in the DMN. However, the IGD group demonstrated increased FC within the cognitive network compared with both ibGD and healthy comparison groups.

Children consume too much sugar and not enough fruit and vegetables, increasing their risk of adverse health outcomes. Inhibitory control training (ICT) reduces children's and adults' intake of energy-dense foods in both laboratory and real-life settings. However, no studies have yet examined whether ICT can increase healthy food choice when energy-dense options are also available. We investigated whether a food-specific Go/No-Go task could influence the food choices of children aged 4-11, as measured by a hypothetical food choice task using healthy and unhealthy food images printed on cards. Participants played either an active game (healthy foods = 100% go, unhealthy foods = 100% no-go; Studies 1 & 2), a food control game (both healthy and unhealthy foods = 50% go, 50% no-go; Studies 1 & 2) or a non-food control game (sports equipment = 100% go, technology = 100% no-go; Study 2 only) followed by the choice task. In Study 2, food card choices were also measured before training to examine change in choices. A post-training real food choice task was added to check that choices made in the card-based task were representative of choices made when faced with real healthy and unhealthy foods. Overall, the active group chose the greatest number of healthy food cards. Study 2 confirmed that this was due to increases in healthy food card choice in this group only. Active group participants chose a greater number of healthy foods in the real food choice task compared to children in the non-food control group only. The results are discussed with reference to methodological issues and the development of future healthy eating interventions. Copyright © 2017 The Authors. Published by Elsevier Ltd..

Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME), and Multiple Sclerosis (MS) may share some similarities in relation to reduced NK cell activity. It is likely that other cells such as regulatory T (Tregs), invariant Natural Killer T (iNKT) and gamma delta T (γδ T) cells may also be dysregulated in CFS/ME and MS. To evaluate and compare specific immune regulatory cells of patients with CFS/ME, patients with MS and healthy controls. Sixty three volunteers were included in this study: 24 were CFS/ME patients, 11 were MS patients and 27 were healthy controls. Blood samples were obtained from all participants for flow cytometry analysis of iNKT cells, Tregs and γδ T cell phenotypes. We observed a significant increase in Tregs in the CFS/ME group (p≤0.05) compared to the healthy control group. Total γδ and γδ2 T cells were significantly reduced in MS patients in comparison with the healthy control group. Conversely, CD4+iNKT percentage of iNKT, was significantly increased in the CFS/ME group compared with healthy controls and the double-negative iNKT percentage of iNKT significantly decreased compared with the healthy control group. This study has not identified any immunological disturbances that are common in both MS and CFS/ME patients. However, the differential expression of cell types between the conditions investigated suggests different pathways of disease. These differences need to be explored in further studies.

To determine possible differences in single-hop kinematics and kinetics in females with anterior cruciate ligament reconstruction compared to healthy controls. A second purpose was to make comparisons between the healthy and reconstructed limbs. Subjects were grouped based on surgical status (33 ACLR patients and 31 healthy controls). 3D motion capture synchronized with force plates was used to capture the landing phase of three successful trials of single hop for distance during a single data collection session. Peak values during the loading phase were analysed. Subjects additionally completed three successful trials of the triple hop for distance Tegner activity scale and International Knee Document Committee 2000 (IKDC). Controls demonstrated greater peak knee flexion and greater internal knee extension moment and hip extension moment than ACLR subjects. Within the ACLR group, the healthy limb exhibited greater peak knee flexion, hip flexion, hip extension moment, single hop and triple hops for distance and normalized quadriceps strength. Patients who undergo anterior cruciate ligament reconstruction land in a more extended posture when compared to healthy controls and compared to their healthy limb. III.

[Purpose] To examine the effects of lumbopelvic sling and abdominal drawing-in exercises on the lung capacities of healthy subjects. [Subjects and Methods] Twenty-nine healthy subjects with no orthopedic history of the back were recruited. Subjects were randomly assigned to a experimental group and control group. Subjects were allocated to one of two groups; an experimental group that underwent lumbopelvic sling and abdominal drawing-in exercises and a control group that underwent treadmill and abdominal drawing-in exercises. Lung capacities were evaluated 4 weeks after exercises. [Results] The experimental group showed significant increments in EV, ERV, IRV, VT vs. pre-intervention results, and the control group showed significant increments in the EVC and IRV. Significant intergroup differences were observed in terms of post-training gains in EVC, IRV, and VT. [Conclusion] Combined application of lumbopelvic sling and abdominal drawing-in exercises were found to have a positive effect on lung capacity.

Central adiposity and metabolic syndrome are quite common among postmenopausal women. Dietary diversity and healthy food choices have essential role in health and also in prevention of obesity. The main objective of this study was to evaluate the impact of mobile phone short messaging system on healthy food choices among Iranian postmenopausal women. This was a randomized controlled trial in which 100 postmenopausal women aged 40-60 years were recruited and assigned to two groups (50 each in the intervention and control groups). Food frequency consumption was measured using a questionnaire. A total of 16 text messages including information about modification of food selection (healthy choices, benefits, methods, etc.,) were sent to participants in the intervention group during 4 months follow-up (1/week). The Chi-square and independent t-test used for data analysis. Ninety-two women completed the study. The consumption of Vitamin A rich fruits and vegetables significantly increased in the intervention group compared to the control group (P < 0.001). More women in the intervention group consumed fish after intervention (P = 0.02). The consumption of green leafy vegetables showed a nonsignificant increase in the intervention group. Using mobile phone short messaging system can improve the healthy food choices regarding Vitamin A rich fruits and vegetables and fish among postmenopausal women.

To investigate the alteration and its significance of T help 17 cells (Th17) in patients with chronic lymphocytic thyroiditis (CLT). Patients were divided into 3 groups: CLT patients with euthyroidism (n=15), CLT patients with hypothyroidism (n=30) and healthy control group (n=20). The ratio of Th17 lymphocytes subpopulations in the peripheral blood were evaluated by technique of flow cytometry. Production of thyroid autoantibody (TPO-Ab, TG-Ab) were measured by electro-chemiluminescence immunoassay (ECLIA). Compared with the healthy control group, in CLT group: The frequencies of Th17 in peripheral blood were found to be significantly higher in patients with CLT than healthy control group (P<0.01); Production of TPO-Ab and TG-Ab markedly increased in CLT patients than healthy control group (P<0.01). There was significant correlation between the positive expression of thyroid autoantibody and the changes of Th17 subpopulations (r=0.50, r=0.43 respectively; P<0.01). The frequencies of Th17 cell increased in patients with CLT which may suggest a potential role for Th17 in the progression and happen of CLT.

Language assessment seems to be an effective tool to differentiate healthy and cognitively impaired aging groups. This article discusses the impact of educational level on a naming task, on a verbal learning with semantic cues task and on the MMSE in healthy aging adults at three educational levels (very low, low and high) as well as comparing two clinical groups of very low (0-3 years) and low education (4-7 years) patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI) with healthy controls. The participants comprised 101 healthy controls, 17 patients with MCI and 19 with AD. Comparisons between the healthy groups showed an education effect on the MMSE, but not on naming and verbal learning. However, the clinical groups were differentiated in both the naming and verbal learning assessment. The results support the assumption that the verbal learning with semantic cues task is a valid tool to diagnose MCI and AD patients, with no influence from education.

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

A case-control study is the most powerful design to test the risk of specific congenital malformations associated with a specific drug. However, malformation registries often lack non-malformed controls. For the Dutch EUROCAT, we collected a non-malformed control group: the 'Healthy Pregnant'. The aim of this study was to evaluate the representativeness of this control group for the general pregnant population in the northern part of the Netherlands. The Healthy Pregnant data set includes data from two midwife practices. The baseline characteristics of mother and child including smoking status, drinking status, body mass index, maternal age, educational level, exposures to several drugs for chronic diseases and pregnancy related symptoms were evaluated. Compared with the general population, mothers in Healthy Pregnant group (n = 556) were from either low or high education level, were more likely to have a body mass index > 25 kg/m² (26% versus 22%, p = 0.08) or to smoke (19% versus 10%, p < 0.01) but were less likely to consume alcohol (20% versus 29%, p < 0.01). The use of drugs for chronic conditions was lower in Healthy Pregnant group. Furthermore, drugs for occasional use were prescribed less frequently, and a significant underreporting of children with a low birth weight and a short duration of gestation was found. The Healthy Pregnant data set was not representative of the general pregnant population in the northern part of the Netherlands. Specifically, the exposure to (chronic) drugs was underestimated, possibly a result of second-line care on the basis of medical indication. Thus, continuous investigation of options for improvement of the Healthy Pregnant database is required. Copyright © 2011 John Wiley & Sons, Ltd.

Short-term intake of a Japanese-style healthy lunch menu contributes to prevention and/or improvement in metabolic syndrome among middle-aged men: a non-randomized controlled trial

PubMed Central

2014-01-01

Background Metabolic syndrome is now widely appreciated as a cluster of metabolic abnormalities such as visceral obesity, hypertension, hyperglycemia and dyslipidemia. To date, incidence of metabolic syndrome is continuously increasing worldwide. In addition, low vegetable consumption has recently become a serious issue in Japan. Furthermore, Japan is facing a shortfall in places offering food that can help prevent metabolic syndrome in the first place. Our study is designed to influence these developments. We conducted a non-randomized controlled trial by offering a Japanese-style healthy lunch menu to middle-aged men in a workplace cafeteria. This menu was designed to prevent and reduce metabolic syndrome. Methods This intervention study took the form of a non-randomized controlled trial. Participants chose the control or intervention group. The control group consumed their habitual lunches without restriction and only nutrient contents were assessed. The intervention group received a Japanese-style healthy lunch at a workplace cafeteria for 3 months. The participants worked in offices at a city hall and mostly had low levels of physical activity. Data of 35 males (control group: 7 males, intervention group: 28 males, mean age: 47.2 ± 7.9 years) were collected and analyzed. Results We obtained an effective outcome by demonstrating that ongoing intake of a Japanese-style healthy lunch decreased blood pressure and serum lipids and increased plasma ghrelin levels. The results grew more pronounced as intake of Japanese-style healthy lunches increased in frequency. Conclusions This study presents new empirical data as a result of an original intervention program undertaken in Japan. A Japanese-style healthy lunch menu containing many vegetables consumed can help prevent and/or improve metabolic syndrome. PMID:24673894

Residual effects of hypnotics on driving performance have been mainly determined in studies using a standardized driving test with healthy good sleepers. Responses to effects may differ, however, between insomniacs and healthy volunteers due to the underlying sleep disorder. In addition, a majority of insomniacs uses hypnotics chronically resulting in the development of tolerance to impairing effects. Impaired driving performance in healthy volunteers may then be an overestimation of the actual effects in insomniacs. The present study aims to compare the residual effects of zopiclone 7.5 mg on on-the-road driving performance of 16 middle-aged insomniacs chronically using hypnotics (chronic users), 16 middle-aged insomniacs not or infrequently using hypnotics (infrequent users), and 16 healthy, age matched, good sleepers (controls). The study was conducted according to a 3 × 2 double-blind, placebo controlled crossover design, with three groups and two treatment conditions. Treatments were single oral doses of zopiclone 7.5 mg and placebo administered at bedtime (2330 hours). Between 10 and 11 h after administration subjects performed a standardized highway driving test. Zopiclone 7.5 mg significantly impaired on-the-road driving performance in both insomnia groups and healthy controls. The magnitude of impairment was significantly less in the chronic users group as compared with the controls. The smaller magnitude of effects suggests that investigating residual effects of hypnotics in healthy volunteers may yield a minor overestimation of the actual effects in insomnia patients.

 This study was planned to investigate whether smoker chronic periodontitis patients exhibit different salivary concentrations of C-telopeptide pyridinoline cross-links of type I collagen (ICTP) and osteocalcin (OC) compared to the non-smoker counterparts. Whole saliva samples, full-mouth clinical periodontal recordings were obtained from 33 otherwise healthy chronic periodontitis patients and 36 systemically, periodontally healthy control subjects. Chronic periodontitis patients and healthy control subjects were divided into smoker and non-smoker groups according to their self reports. Salivary ICTP, OC levels were determined by Enzyme-linked Immunoassays. Healthy control groups exhibited significantly lower values in all clinical periodontal measurements (P < 0.001). Smoker periodontitis patients revealed similar clinical periodontal index values with non-smoker counterparts (P > 0.05). Chronic periodontitis patients exhibited significantly higher salivary OC levels than healthy controls (P < 0.05). Smoker periodontitis patients revealed lower salivary OC levels than non-smoker counterparts (P < 0.001). Log ICTP levels in non-smoker chronic periodontitis patients were higher than non-smoker controls (P < 0.05). Smoker healthy control group revealed higher log ICTP levels than non-smoker counterparts (P < 0.001). Within the limits of this study, it may be suggested that suppression of salivary osteocalcin level by smoking may at least partly explain the deleterious effects of smoking on periodontal status. © 2010 John Wiley & Sons A/S.

The aim of the present preliminary randomized controlled study was to ascertain whether the use of newly developed nanotechnologies-based patches can influence posture control of healthy subjects. Thirty healthy female subjects (age 39.4 years, BMI 22.74 kg/m2) were randomly assigned to two groups: one with active patches and a control group with sham patches. Two patches were applied with a tape: one on the subject's sternum and the other on the C7 apophysis. Body sway during quiet upright stance was recorded with a dynamometric platform. Each subject was tested under two visual conditions, eyes open and closed. We used a blocked stratified randomization procedure conducted by a third party. Subjects wearing the sham patches showed a significant increase of the centre of pressure sway area after 4 hours when they performed the habitual moderate-intensity work activities. In the active patch group, a decrease of the sway path was evident, providing evidence of an enhanced balance control. Our preliminary findings on healthy subjects indicate that nanotechnological devices generating ultra-low electromagnetic fields can improve posture control.

Developmental changes in cognitive and affective processes contribute to adolescent risk-taking behavior, emotional intensification, and psychopathology. The current study examined adolescent development of cognitive control processes and their modulation by incentive, in health and psychopathology. Predictions include 1) better cognitive control in adults than adolescents, and in healthy adolescents than anxious and depressed adolescents, and 2) a stronger influence of incentives in adolescents than adults, and in healthy adolescents than their depressed and anxious counterparts. Antisaccadic eye movement parameters, which provide a measure of cognitive control, were collected during a reward antisaccade task that included parameterized incentive levels. Participants were 20 healthy adults, 30 healthy adolescents, 16 adolescents with an anxiety disorder, and 11 adolescents with major depression. Performance accuracy and saccade latency were analyzed to test both developmental and psychopathology hypotheses. Development and psychopathology group differences in cognitive control were found. Specifically, adults performed better than healthy adolescents, and healthy adolescents than anxious and depressed adolescents. Incentive improved accuracy for all groups; however, incremental increases were not sufficiently large to further modulate performance. Incentives also affected saccade latencies, pushing healthy adolescent latencies to adult levels, while being less effective in adolescents with depression or anxiety. This latter effect was partially mediated by anxiety symptom severity. Current findings evidence the modulation of cognitive control processes by incentives. While seen in both healthy adults and healthy adolescents, this modulatory effect was stronger in youth. While anxious and depressed adolescents exhibited improved cognitive control under incentives, this effect was smaller than that in healthy adolescents. These findings suggest differential incentive and/or cognitive control processing in anxiety and depression, and across development. Differences could result from disorder specific, or combined developmental and pathological mechanisms.

Incentive improved accuracy for all groups; however, incremental increases were not sufficiently large to further modulate performance. Incentives also affected saccade latencies, pushing healthy adolescent latencies to adult levels, while being less effective in adolescents with depression or anxiety. This latter effect was partially mediated by anxiety symptom severity. Conclusions Current findings evidence the modulation of cognitive control processes by incentives. While seen in both healthy adults and healthy adolescents, this modulatory effect was stronger in youth. While anxious and depressed adolescents exhibited improved cognitive control under incentives, this effect was smaller than that in healthy adolescents. These findings suggest differential incentive and/or cognitive control processing in anxiety and depression, and across development. Differences could result from disorder specific, or combined developmental and pathological mechanisms. PMID:17501725

It was aimed to evaluate KL-6 glycoprotein levels to determine if it may be a diagnostic marker for the connective tissue diseases (CTDs) predicting CTD-related interstitial lung diseases (ILDs) (CTD-ILD) development and to examine if there was a difference between patients and healthy controls. The study included 113 patients with CTD (45 CTD without lung involvement, 68 CTD-ILD) and 45 healthy control subjects. KL-6 glycoprotein levels were analyzed with ELISA in patients and the control group. The relationship between KL-6 glycoprotein levels and CTD-ILD was assessed. In the comparison of all the groups in the study, significantly higher levels of KL-6 were determined in the CTD-ILD group than in either the CTD without pulmonary involvement group or the healthy control group (p < 0.008 and p < 0.001, respectively). There was no statistically significant difference between the KL-6 levels in the healthy control group and the CTD without pulmonary involvement group (p = 0.289). The KL-6 levels did not differ significantly according to the connective tissue diseases in the diagnostic groups (systemic lupus erythematosus, Sjögren's syndrome, rheumatoid arthritis, mixed connective tissue disease, scleroderma, polymyositis/ dermatomyositis). In the healthy control group, there was a statistically significant difference between KL-6 levels in smokers and non-smokers. Smokers had significantly higher serum KL-6 levels compared with non-smokers (p < 0.05). There was no statistically significant difference between smoking status (pack-year) and serum KL-6 levels. There was no statistically significant correlation between serum KL-6 levels and time since diagnosis of CTD and CTD-ILD. The level of KL-6 as a predictive factor could be used to identify the clinical development of ILD before it is detected on imaging modality. Further prospective clinical studies are needed to define whether levels of KL-6 might have prognostic value or might predict progressive ILD.

To determine the normal serum levels of LDL-cholesterol, apolipoprotein-B, ferritin, uric acid, and the extent of erythrocytes lipid peroxidation in healthy control group subjects and to compare them with coronary heart disease patients. Secondly, to study the effects of age and sex on these parameters. The blood samples from 150 healthy Libyan control group subjects (110 men and 40 women) were classified into 3 groups according to their age. Group I consisted of 76 subjects with an age range from 20 to 35 years. Group II consisted of 45 subjects with an age range from 36 to 50 years. Group III consisted of 29 subjects with an age range from 51 to 74 years. The blood samples from these groups were analyzed for LDL-cholesterol, apolipoprotein-B, ferritin and uric acid levels. Lipid peroxidation was compared in the erythrocytes of 56 selected healthy control group subjects (31 men and 11 women) of the aforementioned age groups. These parameters have shown age-dependent elevation in their levels. Meanwhile, LDL-cholesterol and Apolipoprotein-B levels in female subjects were higher than those of males. However, lipid peroxidation in the erythrocytes has revealed a statistically significant increase with increasing age. The comparison between 93 selected, sex and age matched, healthy control group subjects with 87 selected coronary heart disease patients (55 men and 45 women) with an age range from 30 to 74 years (49.6+13.25) has demonstrated significantly higher concentration of LDL-cholesterol, Apolipoprotein-B, ferritin and uric acid in coronary heart disease patients than those of healthy control group subjects. Meanwhile, lipid peroxidation was also significantly enhanced in coronary heart disease patients compared with healthy control group subjects. Our study has revealed that an increase in the lipid peroxidation in erythrocytes with age and during coronary heart disease, makes red cell membranes more vulnerable to free radical damage via formation of reactive oxygen species. It is thus likely that peroxidative damage may be contributing to an increase in serum LDL-cholesterol, Apolipoprotein-B, probably after its oxidative modification, increase in ferritin and hyperuricemia in coronary heart disease patients.

In this work authors show a diagnostic criteria in study of TMID: neuro occlusal clinical evaluation (NOE), T-Scan 2 system and surface electromyography (sEMG). Nine patients 25-30 years old with TMID problem and 9 healthy group control have been selected and examined. On each patients it has been performed NOE, T-Scan and sEMG test. NOE has been calculated on each patient photos lateral mandibular excursion angle called: masticatory functional angle (AFM). T-Scan System is a computerized occlusal analyzer that provide in-depth understanding of the overall balance of the occlusion. At the same time of T-Scan record sEMG tests, in resting position and in maximum clench, have been performed. In healthy control there were no AFM difference. In no healthy group there were difference between the two AFM greater than 6 degrees. T-Scan COF showed how in healthy group control there was never a difference of COF greater than 5%. In no healthy group the difference were greater than 5% P<0.05. T-scan showed difference of time force in maximum intercuspidation (MIFT) in healthy respect TMID patients. In healthy patients MIFT was higher than TMID patients P<0.05. sEMG test showed in non healthy group a great asymmetrical activation of masseter (MM). MM activation were greater on side affected by joint sound than the balance side P<0.001. sEMG show how in TMID patients maximum masseter activation is always lower than maximum masseter activation of healthy subjects P<0.001. Neuro occlusal clinical evaluation (NOE) in TMID patients is supported by instrumental evaluation.

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

Previous studies suggest central nervous system involvement in chronic fatigue syndrome (CFS), yet there are no established diagnostic criteria. CFS may be difficult to differentiate from clinical depression. The study's objective was to determine if spectral coherence, a computational derivative of spectral analysis of the electroencephalogram (EEG), could distinguish patients with CFS from healthy control subjects and not erroneously classify depressed patients as having CFS. This is a study, conducted in an academic medical center electroencephalography laboratory, of 632 subjects: 390 healthy normal controls, 70 patients with carefully defined CFS, 24 with major depression, and 148 with general fatigue. Aside from fatigue, all patients were medically healthy by history and examination. EEGs were obtained and spectral coherences calculated after extensive artifact removal. Principal Components Analysis identified coherence factors and corresponding factor loading patterns. Discriminant analysis determined whether spectral coherence factors could reliably discriminate CFS patients from healthy control subjects without misclassifying depression as CFS. Analysis of EEG coherence data from a large sample (n = 632) of patients and healthy controls identified 40 factors explaining 55.6% total variance. Factors showed highly significant group differentiation (p < .0004) identifying 89.5% of unmedicated female CFS patients and 92.4% of healthy female controls. Recursive jackknifing showed predictions were stable. A conservative 10-factor discriminant function model was subsequently applied, and also showed highly significant group discrimination (p < .001), accurately classifying 88.9% unmedicated males with CFS, and 82.4% unmedicated male healthy controls. No patient with depression was classified as having CFS. The model was less accurate (73.9%) in identifying CFS patients taking psychoactive medications. Factors involving the temporal lobes were of primary importance. EEG spectral coherence analysis identified unmedicated patients with CFS and healthy control subjects without misclassifying depressed patients as CFS, providing evidence that CFS patients demonstrate brain physiology that is not observed in healthy normals or patients with major depression. Studies of new CFS patients and comparison groups are required to determine the possible clinical utility of this test. The results concur with other studies finding neurological abnormalities in CFS, and implicate temporal lobe involvement in CFS pathophysiology.

Introduction In the current study we aimed to determine body image, self-esteem and depressive symptomatology in women with Polycystic ovary syndrome (PCOS) and compare with healthy controls. Method This study was conducted among the patients with untreated PCOS who admitted to the Outpatient Clinic of Gynecology and Obstetrics of Faculty of Medicine of Selçuk University. A total 83 consecutive women with PCOS met the criteria of present study were included in the study. Age matched healthy controls (n=64) were recruited from employees at Selçuk University Hospital. PCOS was defined according to Rotterdam criteria. After socio-demographic characteristics of the participants were recorded, Body Image Scale, Rosenberg Self-Esteem Scale and Beck Depression Inventory were completed by the participants. Results Patients with PCOS and healthy controls did not differ in some sociodemographic variables, including age, education and economic status (p>.05). Previous psychiatric history was more prevalent among the PCOS group (p<. 05). Body mass index (BMI) was ≤25 kg/m2 in both groups. BMI values in the PCOS group were significantly higher than in the controls (p<.05). BDI scores were significantly higher in the PCOS group compared to that in the healthy controls (p<.05). There was no significant difference between the PCOS group and healthy controls in BIS and RSES scores (p>.05). Conclusion The present study suggests that PCOS seems to be associated with depressive symptomatology. Furthermore, rising BMI values of these women may be an indicator for the onset of PCOS. However, these results should be confirmed by prospective studies. PMID:28360612

In this study, we investigated the pro- and antioxidant status of patients with a pathogenesis of Crimean-Congo hemorrhagic fever (CCHF) in terms of their role in its pathogenesis. During the study period, 34 children and 41 adults were diagnosed with CCHF. The control group consisted of healthy age- and gender-matched children and adults. Serum levels of the total antioxidant capacity (TAC), total oxidant status (TOS), oxidative stress index (OSI), and plasma total thiol (TTL) were evaluated and compared between groups. The difference in mean TAC values between CCHF patients and healthy controls was not statistically significant (P > 0.05). Mean TOS, OSI, and TTL values were significantly lower in CCHF patients than in healthy controls (P < 0.001). Comparisons between the 2 groups revealed that mean TOS and OSI values were significantly lower in adults with CCHF than in their healthy counterparts (P < 0.001). Similarly, mean TTL levels were lower in both children and adults with CCHF when compared separately with healthy controls (P < 0.05). There was no significant difference in the mean serum TTL levels between children and adults with CCHF (P > 0.05). Our results suggest that TTL may play a more important role in CCHF pathogenesis than the other parameters investigated. The mean TOS and OSI values were higher in the control group than in CCHF patients.

Little is known about laypeople's practical understanding of a healthy diet, although this is important to successfully promote healthy eating. The present study is the first to experimentally examine how consumers define healthy and balanced food choices for an entire day compared with normal choices and compared with dietary guidelines. We used an extensive fake food buffet (FFB) with 179 foods commonly consumed in the Swiss diet. The FFB is a validated method to investigate food choice behaviour in a well-controlled laboratory setting. People from the general population in Switzerland (n 187; 51·9 % females), aged between 18 and 65 years, were randomly assigned to one of two conditions. In the control group, the participants were instructed to serve themselves foods they would eat on a normal day, whereas in the 'healthy' group they were instructed to choose foods representing a healthy diet. Participants chose significantly more healthy foods, with 4·5 g more dietary fibre, 2 % more protein and 2 % less SFA in the 'healthy' group compared with the control group. However, in both experimental conditions, participants served themselves foods containing twice as much sugar and salt than recommended by dietary guidelines. The results suggest that laypeople lack knowledge about the recommended portion sizes and the amounts of critical nutrients in processed food, which has important implications for communicating dietary guidelines. Furthermore, the energy of the food served was substantially correlated with the energy needs of the participants, demonstrating the potential of the fake food buffet method.

Patients with diabetes mellitus (DM) are prone to atherosclerosis. Atherosclerosis activates platelets; activated platelets release serotonin, and therefore, evaluation of serotonin levels in blood could be a valuable biomarker for future risk of cardiovascular events. Plasma serotonin levels obtained from patients with DM complicated with chronic kidney disease were measured using HPLC and were compared to serotonin levels of healthy control subjects. Patients with DM were classified into 2 subgroups of mildly (group 1) and moderately/severely (group 2) impaired renal function. Serotonin concentration in platelet-poor plasma for group 1 was significantly higher than that of healthy control subjects (p < 0.01), and was significantly higher than that of patients from group 2 (p < 0.05). The concentration of serotonin in whole blood for group 2 patients was significantly lower than that measured from healthy control subjects (p < 0.01). The ratio of the plasma to whole blood level was significantly elevated in both groups 1 and 2 compared with healthy controls (p < 0.01). Our results indicate that platelets are activated to release serotonin into plasma in diabetic patients with mildly impaired renal function. When renal damage is advanced, platelets are over-activated to release serotonin. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

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.

To test whether aerobic exercise can help build self-control stamina in healthy female young adults. Stamina in this context is defined as the capability to endure ego depletion, which can be measured with a self-control task following another activity also requiring self-control. Forty-five healthy undergraduate women were randomized to either an experimental group or control group. Participants in the experimental group were required to run in their campus running field for 30 min for a period of 5 weeks. Individuals in the control group were required to do diary entries regarding self-control in their daily lives, also for a period of 5 weeks. Before and after the 5-week intervention, participants completed a pain threshold test, a color word Stroop task and the following Cold Pressor Task (CPT) (with and without a distraction component). There was significant decrease of pain tolerance in session 2 relative to session 1 in the control group, but no such decline was found in the experimental group (though the improvement of pain tolerance was not significant), possibly suggesting successful self-control against this kind of decline. Five weeks of aerobic exercise increased self-control after ego depletion in terms of pain tolerance. These findings suggest that aerobic exercise may serve as a potential effective intervention for enhancing self-control in a college female population.

The PAQ questionnaire (Physical Activity Questionnaire - Kowalski, Crocker, Donen) is a self-administered 7-day recall validated questionnaire that measures physical activity levels in young people. A final activity score is obtained (1 indicates low and 5 indicates high physical activity level). Our aim was to determine whether there was any difference between the level of physical activity of children with controlled allergic disease and healthy children. We used the PAQ questionnaire with a group of asthmatic children attending hospital outpatient clinic and a group of healthy children matched for age. 155 children with allergic disease (median age of 11 years; 63% males) and 158 healthy controls (median age of 10 years; 46% males) answered the questionnaire. There were no differences in the overall level of physical activity, estimated by PAQ score, between allergic and healthy children (2,40±0,7 vs 2,48±0,62; p=0,32). Performance in physical education classes and after school sports activity was found to be different between the study groups; healthy children were more active (p=0,011) and did more sports between 6 and 10 pm (p=0,036). No other statistically significant differences were found between the study groups. Despite the fact that a majority of the parents of allergic children stated that their child's disease was a barrier to physical activity, in our study there seems to be no difference between the level of physical activity of controlled asthmatic children and their healthy peers.

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

Objectives To evaluate the efficacy of mnemonic strategy training versus a matched-exposure control condition and also to examine the relationship between training-related gains, neuropsychological abilities, and medial temporal lobe volumetrics in patients with amnestic mild cognitive impairment (aMCI) and age-matched healthy controls. Methods Twenty-three of 45 screened healthy controls and 29 of 42 screened aMCI were randomized to mnemonic strategy or matched-exposure groups. Groups were run in parallel, with participants blind to the other intervention. All participants completed five sessions within two weeks. Memory testing for object-location associations was performed during sessions one and five and at a one-month follow-up. During sessions 2–4, participants received either mnemonic strategy training or a matched number of exposures with corrective feedback for a total of 45 object-location associations. Structural MRI was performed in most participants and medial temporal lobe volumetrics were acquired. Results Twenty-one healthy controls and 28 aMCI patients were included in data analysis. Mnemonic strategy training was significantly more beneficial than matched-exposure immediately after training, p =.006, pη2 = .16, and at one month, p<.001, pη2 = .35, regardless of diagnostic group (healthy controls or aMCI). Although aMCI patients demonstrated gains comparable to the healthy control groups, their overall performance generally remained reduced. Mnemonic strategy-related improvement was positively correlated with baseline memory and executive functioning and negatively with inferior lateral ventricle volume in aMCI patients; no significant relationships were evident in matched-exposure patients. Conclusions Mnemonic strategies effectively improve memory for specific content for at least one month in aMCI. PMID:22409311

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.

This study first time reports the hypoglycaemic activity of crude seeds powder (CSP) of Centratherum anthelminticum in healthy and type 2 diabetic volunteers. In addition, hypolipidemic effect of same CSP was also determined in healthy volunteers. Healthy individuals were divided into control and two test groups T1 and T2 treated with 200 & 400mg of CSP. Similarly, type 2 diabetic patients were also divided into positive control (PC) treated with metformin 600mg and two test groups DT1 (CSP 400mg + metformin 600mg) & DT2 (CSP 400mg). Each group has 6 individuals and each treatment was done orally. CSP 400mg was found more hypoglycaemic on all time intervals from 30 to 120min when oral glucose tolerance test was conducted in healthy volunteers. Both test quantities of CSP 200 & 400 mg were found successful in same healthy persons in decreasing the levels of triglycerides & total cholesterol (p<0.05), low & very low density lipoprotein cholesterols (p<0.01) and keeping the level of high density lipoprotein cholesterol as same as it was observed in control group. Similarly, CSP 400mg along with metformin and alone was also found helpful in lowering the fasting blood glucose levels in type 2 diabetic patients (DT1 & DT2) -24.99% and -20.62% respectively as compared to diabetic group only treated with metformin (PC), (p<0.01). Therefore, CSP of C antheminticum proves effective hypoglycaemic and hypolipidemic agent by possibly inducing glucose tolerance in healthy individuals and type 2 diabetic patients.

The cervical flexion relaxation ratio is lower in neck pain patients compared to healthy controls. Fatigue modulates the onset and offset angles of the silent period in both the lumbar and cervical spine in healthy individuals; however, this response has not been studied with neck pain patients. The purpose of this study was to determine if cervical extensor fatigue would alter the parameters of the cervical flexion relaxation more in a neck pain group than a healthy control group. Thirteen healthy and twelve neck pain patients participated. Cervical extensor activity was examined bilaterally and kinematics of the neck and head were collected. An isometric, repetitive neck extension task at 70% of maximum elicited fatigue. Participants performed 3 trials of maximal cervical flexion both pre and post fatigue. The healthy controls and neck pain groups fatigued after 56 (41) and 39 (31) repetitions, respectively. There was a significant interaction effect for the flexion relaxation ratio between the control and neck pain groups from pre to post fatigue trials (F1,96=22.67, P=0.0001), but not for onset and offset angles (F1, 96=0.017, P=0.897), although the onset and offset angles did decrease significantly for both groups following fatigue (F1,96=9.26, P=0.002). Individuals with mild to moderate neck pain have significant differences in their neuromuscular control relative to controls, experienced myoelectric fatigue with fewer repetitions in a shorter time, had a lower cervical flexion relaxation ratio at baseline and had an inability to decrease this ratio further in response to fatigue.

The healing effect of BPC 157 on rat femoral head osteonecrosis was monitored by Raman spectroscopy. Three groups of rats were defined: an injured group treated with BPC 157 (10 μg/kg/daily ip), an injured control group (treated with saline, 5 ml/kg/daily ip), and an uninjured healthy group. The spectra were recorded and the healing effect assessed on samples harvested from animals which were sacrificed 3 and 6 weeks after being injured. The statistical analysis of the recorded spectra showed statistical differences between the BPC 157-treated, control, and healthy groups of animals. In particular, after 6 weeks the spectral resemblance between the healthy and BPC 157 samples indicated a positive BPC 157 influence on the healing process of rat femoral head.

2015-09-01

The effects of methadone maintenance treatment (MMT) on neurophysiological function are unclear. Using an auditory oddball paradigm, event-related potential (ERP) amplitudes and latencies were measured in 32 patients undertaking MMT, 17 opiate users who were addicted but not receiving substitution treatment and 25 healthy control subjects. Compared with healthy control subjects, the MMT and opiate user groups showed an increased P200 amplitude in response to target stimuli. The opiate user group also exhibited a decreased amplitude and an increased latency of N200, and a greater number of task-related errors than either healthy control subjects or patients undertaking MMT. There were no significant group differences in the P300 amplitude. However, it is noteworthy that the frontal P300 amplitude of the MMT group was greater than that of opiate users or healthy controls. Our findings suggest that altered sensory information processing associated with a history of opiate use remains in patients undertaking MMT. However, there are less marked ERP abnormalities in those receiving MMT than in active opiate users. The deficits in information processing associated with illicit opiate use are likely to be reduced during MMT. © The Author(s) 2015.

Objective Extreme emotional reactivity is a defining feature of borderline personality disorder, yet the neural-behavioral mechanisms underlying this affective instability are poorly understood. One possible contributor would be diminished ability to engage the mechanism of emotional habituation. We tested this hypothesis by examining behavioral and neural correlates of habituation in borderline patients, healthy controls, and a psychopathological control group of avoidant personality disorder patients. Method During fMRI scan acquisition, borderline patients, healthy controls and avoidant personality disorder patients viewed novel and repeated pictures, providing valence ratings at each presentation. Statistical parametric maps of the contrasts of activation during repeat versus novel negative picture viewing were compared between groups. Psychophysiological interaction analysis was employed to examine functional connectivity differences between groups. Results Unlike healthy controls, neither borderline nor avoidant personality disorder participants showed increased activity in dorsal anterior cingulate cortex when viewing repeat versus novel pictures. This failure to increase dorsal anterior cingulate activity was associated with greater affective instability in borderline participants. In addition, borderline and avoidant participants showed smaller insula-amygdala connectivity increases than healthy participants and did not show habituation in ratings of the emotional intensity of the images as did healthy participants. Borderline patients differed from avoidant patients in insula-ventral anterior cingulate connectivity during habituation. Conclusions Borderline patients fail to habituate to negative pictures as do healthy participants and differ from both healthy controls and avoidant patients in neural activity during habituation. A failure to effectively engage emotional habituation processes may contribute to affective instability in borderline patients. PMID:24275960

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.

Although guilt is a widely accepted feature of depression, there is limited and inconsistent data defining the nature of this symptom. The purpose of the current study was to examine the specificity and nature of guilt in subjects with major depression as compared to patients with another chronic medical illness and healthy controls. Outpatients with current major depressive episode (MDE; n=34), past-MDE (n=22), chronic cardiac illness (n=20) and healthy controls (n=59) were administered the following measures: The Guilt Inventory (GI), State Shame and Guilt Scale (SSGS), 17-item Hamilton Rating Scale for Depression (Ham-D) and the Structured Clinical Interview for DSM-IV. Overall multivariate analysis of covariance comparing mean scores for the six guilt subscales [state-guilt, trait-guilt, moral standards (from the GI); state-guilt, -pride, and -shame (from the SSGS)] across the four groups was significant (F=9.1, df=6:121, p<0.0001). Post-hoc analysis revealed the following differences (each at least p<0.01): for state-guilt (GI), current-MDE>past-MDE>cardiac=healthy controls; for trait-guilt (GI), current-MDE=past-MDE>cardiac=healthy controls; for state-shame, -guilt and -pride (SSGS), current-MDE>past-MDE, past-MDE=cardiac, past-MDE>healthy, cardiac=healthy controls. Among depressed patients, there was significant correlation between Ham-D score and all guilt sub-scales (p<0.01), except moral standards. The cardiac group may have less illness burden than currently depressed. State expression of guilt, shame and low pride distinguish acutely depressed from all other groups, and are highly influenced by severity of depression. Trait-guilt does not differentiate acute from past depressed. Data suggests guilt may represent both an enduring and fluctuating feature of depressive illness over its longitudinal course.

Diabetes is known to influence salivary composition and function, eventually affecting the oral cavity. We thus evaluated saliva samples for levels of glucose, amylase and total protein, and assessed salivary flow rate in diabetics and healthy non-diabetics. We also analyzed these parameters with regard to duration and type of diabetes mellitus and gender, and aimed to assess the interrelationships among the variables included in the study. A total of 120 age- and sex-matched participants were divided into 3 groups of 40 each; the uncontrolled diabetic group, the controlled diabetic group and the healthy non-diabetic group. Salivary investigations were performed using unstimulated whole saliva. Mean salivary glucose levels were found to be significantly elevated in both uncontrolled and controlled diabetics, as compared to healthy non-diabetics. There were significant decreases in mean salivary amylase levels in controlled diabetics when compared to healthy non-diabetics. Other than salivary glucose, no other parameters were found to be markedly affected in diabetes mellitus. Further research is needed to explore the clinical implications of these study results.

The present study was aimed to determine the effect on liver, associated oxidative stress, trace element and vitamin alteration in dogs with sarcoptic mange. A total of 24 dogs with clinically established diagnosis of sarcoptic mange, divided into two groups, severely infested group (n=9) and mild/moderately infested group (n=15), according to the extent of skin lesions caused by sarcoptic mange and 6 dogs as control group were included in the present study. In comparison to healthy control hemoglobin, PCV, and TEC were significantly (P<0.05) decreased in dogs with sarcoptic mange however, significant increase in TLC along with neutrophilia and lymphopenia was observed only in severely infested dogs. The albumin, glucose and cholesterol were significantly (P<0.05) decreased and globulin, ALT, AST and bilirubin were significantly (P<0.05) increased in severely infested dogs when compared to other two groups. Malondialdehyde (MDA) levels were significantly (P<0.01) higher in dogs with sarcoptic mange, with levels highest in severely infested groups. Activity of superoxide dismutase (SOD) (P<0.05) and catalase were significantly (P<0.01) lower in sarcoptic infested dogs when compared with the healthy control group. Zinc and copper levels in dogs with sarcoptic mange were significantly (P<0.05) lower when compared with healthy control group with the levels lowest in severely infested group. Vitamin A and vitamin C levels were significantly (P<0.05) lower in sarcoptic infested dogs when compared to healthy control. From the present study, it was concluded that sarcoptic mange in dogs affects the liver and the infestation is associated with oxidant/anti-oxidant imbalance, significant alteration in trace elements and vitamins.

Purpose: To test whether aerobic exercise can help build self-control stamina in healthy female young adults. Stamina in this context is defined as the capability to endure ego depletion, which can be measured with a self-control task following another activity also requiring self-control. Methods: Forty-five healthy undergraduate women were randomized to either an experimental group or control group. Participants in the experimental group were required to run in their campus running field for 30 min for a period of 5 weeks. Individuals in the control group were required to do diary entries regarding self-control in their daily lives, also for a period of 5 weeks. Before and after the 5-week intervention, participants completed a pain threshold test, a color word Stroop task and the following Cold Pressor Task (CPT) (with and without a distraction component). Results: There was significant decrease of pain tolerance in session 2 relative to session 1 in the control group, but no such decline was found in the experimental group (though the improvement of pain tolerance was not significant), possibly suggesting successful self-control against this kind of decline. Conclusions: Five weeks of aerobic exercise increased self-control after ego depletion in terms of pain tolerance. These findings suggest that aerobic exercise may serve as a potential effective intervention for enhancing self-control in a college female population. PMID:27148113

Purpose The homeobox (Hox) genes a and d controlling limb and genital development influence the digit ratio and the fetal production of testicular androgen, which may result in testicular descent in boys. To assess whether the digit ratio reflects disease status, we investigated the second and fourth finger lengths in children with cryptorchidism, in children with hydrocele as a disease control, and in healthy controls (boys and girls). Materials and Methods One hundred ninety-six children (46 with cryptorchidism, 50 with hydrocele, 50 healthy boys, and 50 healthy girls) who were 6 to 23 months of age were prospectively enrolled. Digit lengths were measured by 2 investigators, and the mean value was recorded. Results The second-to-fourth digit ratios (2D:4Ds) of the left hand in the cryptorchidism group, hydrocele group, healthy boys, and healthy girls were 0.958, 0.956, 0.950, and 0.956, respectively. The 2D:4D values of the right hand were 0.946, 0.945, 0.952, and 0.969, respectively. The right and left 2D:4D ratios were not significantly different among groups. The 2D:4D of both hands was not related to age, weight, or height. Conclusions According to these results, the 2D:4D was not significantly different in boys with cryptorchidism than in boys with hydrocele or in healthy controls (boys and girls) and failed to reflect disease conditions in the infant period.

Describing pain is difficult. Children like to draw, and through their drawing they reveal worrying issues. This study aimed to examine how hospitalized children express pain through drawings, and was carried out by examining children's thematic drawings of pain. A comparison was made between hospitalized children and healthy control groups with respect to the thematic contents and cognitive and emotional characteristics of pain drawings. The drawings were sorted in categories on the basis of content, and cognitive competence and emotional disturbances by the Draw-a-Person procedure. The hospitalized children showed a lower level of cognitive capacity than their healthy controls. The control group children revealed a higher level of emotional disturbance than the hospitalized children. The groups differed in the contents of their drawings. The drawings of the hospitalized children frequently depicted medical procedures, whereas the drawings of the healthy controls depicted more consoling human and family relations.

Research suggests generally impaired cognitive control functions in working memory (WM) processes in amnestic mild cognitive impairment (MCI) and incipient Alzheimer's disease (AD). Little is known how emotional salience of task-irrelevant stimuli may modulate cognitive control of WM performance and neurofunctional activation in MCI and AD individuals. We investigated the impact of emotional task-irrelevant visual stimuli on cortical activation during verbal WM. Twelve AD/MCI individuals and 12 age-matched healthy individuals performed a verbal WM (nback-) task with task-irrelevant emotionally neutral and emotionally negative background pictures during fMRI measurement. AD/MCI individuals showed decreased WM performance compared with controls; both AD/MCI and control groups reacted slower during presentation of negative pictures, regardless of WM difficulty. The AD/MCI group showed increased activation in the left hemispheric prefrontal network, higher amygdala and less cerebellar activation with increasing WM task difficulty compared to healthy controls. Correlation analysis between neurofunctional activation and WM performance revealed a negative correlation between task sensitivity and activation in the dorsal anterior cingulum for the healthy controls but not for the AD/MCI group. Our data suggest compensatory activation in prefrontal cortex and amygdala, but also dysfunctional inhibition of distracting information in the AD/MCI group during higher WM task difficulty. Additionally, attentional processes affecting the correlation between WM performance and neurofunctional activation seem to be different between incipient AD and healthy aging.

The purpose of this study was to investigate differences in brain cortical thickness of systemic lupus erythematosus (SLE) patients with and without episodic memory impairment and healthy controls. We studied 51 patients divided in 2 groups (SLE with episodic memory deficit, n = 17; SLE without episodic memory deficit, n = 34) by the Rey Auditory Verbal Learning Test and 34 healthy controls. Groups were paired based on sex, age, education, Mini-Mental State Examination score, and accumulation of disease burden. Cortical thickness from magnetic resonance imaging scans was determined using the FreeSurfer software package. SLE patients with episodic memory deficits presented reduced cortical thickness in the left supramarginal cortex and superior temporal gyrus when compared to the control group and in the right superior frontal, caudal, and rostral middle frontal and precentral gyri when compared to the SLE group without episodic memory impairment considering time since diagnosis of SLE as covaried. There were no significant differences in the cortical thickness between the SLE without episodic memory and control groups. Different memory-related cortical regions thinning were found in the episodic memory deficit group when individually compared to the groups of patients without memory impairment and healthy controls.

Cannabis is among the most frequently abused substances in the United States. Cognitive control is a contributory factor in the maintenance of substance-use disorders and may relate to treatment response. Therefore, we assessed whether cognitive-control-related neural activity before treatment differs between treatment-seeking cannabis-dependent and healthy individuals and relates to cannabis-abstinence measures during treatment and 1-year follow-up. Cannabis-dependent males (N=20) completed a functional magnetic resonance imaging (fMRI) cognitive-control (Stroop) task before a 12-week randomized controlled trial of cognitive–behavioral therapy and/or contingency management. A healthy-comparison group (N=20) also completed the fMRI task. Cannabis use was assessed by urine toxicology and self-report during treatment, and by self-report across a 1-year follow-up period (N=18). The cannabis-dependent group displayed diminished Stroop-related neural activity relative to the healthy-comparison group in multiple regions, including those strongly implicated in cognitive-control and addiction-related processes (eg, dorsolateral prefrontal cortex and ventral striatum). The groups did not differ significantly in response times (cannabis-dependent, N=12; healthy-comparison, N=14). Within the cannabis-dependent group, greater Stroop-related activity in regions including the dorsal anterior cingulate cortex was associated with less cannabis use during treatment. Greater activity in regions including the ventral striatum was associated with less cannabis use during 1-year posttreatment follow-up. These data suggest that lower cognitive-control-related neural activity in classic ‘control' regions (eg, dorsolateral prefrontal cortex and dorsal anterior cingulate) and classic ‘salience/reward/learning' regions (eg, ventral striatum) differentiates cannabis-dependent individuals from healthy individuals and relates to less abstinence within-treatment and during long-term follow-up. Clinically, results suggest that treatment development efforts that focus on enhancing cognitive control in addition to abstinence may improve treatment outcomes in cannabis dependence.

Purpose The purpose of the present study was to examine the validity and reliability of the Korean version of the Eating Disorder Inventory-2 (EDI-2) in Korean patients with eating disorders and healthy controls, and to investigate cultural differences of EDI-2 between a Korean group and a North American standardization sample. Materials and Methods The Korean version of the EDI-2 was prepared after comprehensive clinical assessment of Korean patients with eating disorders (n=327) as well as female undergraduates (n=176). Results were compared between eating disorder subgroups (anorexia nervosa, bulimia nervosa and eating disorders not otherwise specified) and those of a North American standardization sample and healthy controls. Results The results showed that the Korean EDI-2 had adequate internal consistency (0.77-0.93) and discriminated well between patients with eating disorders and healthy controls on all subscales. Significant differences in EDI-2 subscale scores between the eating disorder groups and the healthy control group were observed; however, there was no discernible difference among the eating disorder subgroups. When compared with a North American standardization sample, the Korean control group showed significantly higher scores for drive for thinness and asceticism. When patient groups were compared, the Korean group showed significantly lower scores for perfectionism. Conclusion As expected, the results accurately reflected psychometric properties of the Korean version of EDI-2 for eating disorder patients in Korea. These findings also suggest that common characteristics for the eating disorder exist as a whole rather than with significant difference between each subgroup. In addition, significant differences between the Korean and the North American groups for both patients and controls also demonstrated specific cultural differences. PMID:23074108

To explore whether the pre-clinical findings that metformin improves lipid metabolism, possibly through modulation of intrahepatic partitioning of fatty acids towards oxidation and away from re-esterification and resecretion as triglycerides (TGs), can be translated to a human setting. We performed a 3-month randomized, placebo-controlled, parallel-group clinical trial in patients with type 2 diabetes (T2D; n = 24) and healthy controls (n = 12). Patients with T2D received either placebo (placebo group) or 1000 mg metformin twice daily (metformin group), while healthy subjects were all treated with metformin (control group). Hepatic fatty acid metabolism was measured by [ 11 C]palmitate positron-emission tomography, hepatic TG secretion and peripheral oxidation by ex vivo labelled [1- 14 C]VLDL-TG and VLDL particle size by TG/apolipoprotein B ratio. Body composition was assessed by dual-energy X-ray and whole-body lipid oxidation by indirect calorimetry. Metformin treatment for 3 months produced the anticipated decrease in fasting plasma glucose (FPG) in the metformin group (FPG 7.9 ± 1.8 mM [study day 1] vs 6.4 ± 1.1 mM [study day 2]), whereas patients in the placebo group and healthy controls had similar FPG levels before and after the trial (mixed model group vs time interaction; P = .003); however, contrary to our hypothesis, metformin treatment did not affect hepatic lipid metabolism or peripheral oxidation. The observed beneficial effects on lipid metabolism during metformin treatment in humans appear to be secondary to long-term alterations in body composition or glucose homeostasis. © 2018 John Wiley & Sons Ltd.

Ultrasonographic studies in healthy volunteers showed that the external anal sphincter (EAS) and internal anal sphincter (IAS) thicknesses were inversely related at rest. The functional importance of the two sphincters in continence control was demonstrated in the relationship between the sum of the thicknesses of the two sphincters and the anal canal resting pressure. The aims of the present study were to assess the morphometric appearance of the anal sphincters by endosonography in faecally incontinent patients and to contrast this with that of older healthy subjects. Twenty-eight female patients with neurogenic faecal incontinence (FI) were studied. An older group of 7 healthy women, aged 41-75 years, and a young group of 11 nulliparous healthy women, aged 20-23 years, served as control groups. Anal endosonography was performed with a radial rotating endoprobe, with the subject in the left lateral position. Conventional anal manometry was performed in all subjects. The EAS in the FI group was thicker than the EAS in the old (p < 0.04) but did not differ from the EAS in the young. The IAS thickness in the FI group did not differ from that in the older group. In both these groups the IAS was thicker than in the young women (p < 0.01). The anal pressures in the FI group were reduced compared with the normal groups (p < 0.04). There was a direct relationship between the two sphincters in FI (p < 0.001). The increased thickness of the IAS in the FI group does not seem to compensate for function and results in a failure of the sphincter mechanism to maintain continence, whereas in healthy elderly subjects the increased IAS thickness appears to be compensatory and important for continence control.

Lichen sclerosus (LS) is a chronic inflammatory condition that is known to arise on the vulva. Many women with LS report vulvar pain, often affecting a patient's quality of life. In this study, the sexual function of LS patients, with and without pain, was compared to control populations. A case-control study to examine the relationship between LS and sexual dysfunction was conducted. A total of 335 women presenting to the gynecology clinic were included in the study: 197 women with biopsy confirmed LS were compared to two control groups (95 asymptomatic women were "healthy" controls and 43 women had vulvovaginal candidiasis) on self-reported current health complaints, medical and surgical history and current symptoms such as pain and itching, type and frequency of sexual activity, and satisfaction with sexual activity. Women with LS reported less frequent sexual activity than healthy controls (p=0.007) and Candida controls (p=0.04). Currently sexually active women with LS were significantly less likely to report vaginal intercourse (71.6%) than healthy controls (89.0%, p=0.003) or Candida controls (100%, p=0.0003), even though similar proportions of all three groups reported that vaginal intercourse was important. Satisfaction towards the quality of current sexual activity was significantly lower among women with LS compared with both the healthy and Candida control groups. 23.7% of women with LS reported that sexual activity was rarely or never satisfactory as compared with 0% of healthy controls (p<0.0001) and 6.5% of Candida controls (p=0.03). Women with LS have less frequent sexual activity and less satisfying sexual activity when compared with controls.

Purpose To assess the effect of extracorporeal shock wave therapy (ESWT) for healthy participants with hamstring tightness. Materials and Methods This study was performed at a university rehabilitation hospital. Twenty nine healthy adults with hamstring tightness were enrolled and randomly allocated into four groups (ESWT, stretching exercise, ESWT with stretching exercise, and control). The effects of individual treatments were compared by the finger-to-floor test and popliteal angle. Results The ESWT group, stretching exercise group and ESWT with stretching exercise group had decreased finger-to-floor distances and right popliteal angles immediately after intervention, compared with the control group (p<0.05). At 4 weeks after completion of the interventions, finger-to-floor distances and the right popliteal angle in only the ESWT with stretching exercise group showed a significant improvement, compared with the control group (p=0.008 and 0.023). Conclusion While ESWT and stretching both reduced hamstring tightness immediately after interventions, only ESWT with stretching exercise maintained the significantly improved relief of hamstring tightness significantly after 4 weeks.

Some previous studies have suggested that patients with social anxiety disorder (SAD) have a hypoactive central dopaminergic system. Supporting this there have been reports from neuroimaging studies of reduced striatal D2 receptor binding in subjects with SAD. The aim of this study was to investigate D2 receptor sensitivity in patients with SAD compared with a group of matched, healthy controls using a neuroendocrine challenge with the selective D2 antagonist, sulpiride. D2 receptor function was assessed in 23 subjects with generalized SAD and 23 matched, healthy controls using a challenge with 400 mg of a selective D2 antagonist, sulpiride in a randomized, placebo-controlled, crossover design. Response to sulpiride was measured by the change in prolactin level and changes in self-rated measures of social anxiety, mood and the ability to experience pleasure. There was no significant difference in prolactin response to sulpiride between the two groups. Sulpiride resulted in no effect in either the SAD or healthy control group on measures of social anxiety, mood or the ability to experience pleasure. Contrary to our hypothesis, in this study we found no evidence of reduced D2 receptor function in subjects with SAD compared with healthy controls.

PurposeTo study neuroretinal alterations in patients affected by type 2 diabetes with no diabetic retinopathy (DR) or mild nonproliferative diabetic retinopathy (NPDR) and without any sign of diabetic macular edema.Patients and methodsIn total, 150 type 2 diabetic patients with no (131 eyes) or mild NPDR (19 eyes) and 50 healthy controls were enrolled in our study. All underwent a complete ophthalmologic examination, including Spectral-Domain optical coherence tomography (SD-OCT). Ganglion cell-inner plexiform layer (GC-IPL) and retinal nerve fiber layer (RNFL) thickness values were calculated after automated segmentation of SD-OCT scans.ResultsMean best-corrected visual acuity was 0.0±0.0 LogMAR in all the groups. Mean GC-IPL thickness was 80.6±8.1 μm in diabetic patients and 85.3±9.9 μm in healthy controls, respectively (P=0.001). Moreover, evaluating the two different diabetic groups, GC-IPL thickness was 80.7±8.1 μm and 79.7±8.8 μm in no-DR and mild-NPDR group (P=0.001 and P=0.022 compared with healthy controls, respectively). Average RNFL thickness was 86.1±10.1 μm in diabetes patients and 91.2±7.3 μm in controls, respectively (P=0.003). RNFL thickness was 86.4±10.2 μm in no-DR group and 84.1±9.4 μm in mild-NPDR group (P=0.007 and P=0.017 compared with healthy controls, respectively).ConclusionWe demonstrated a significantly reduced GC-IPL and RNFL thickness values in both no-DR and mild-NPDR groups compared with healthy controls. These data confirmed neuroretinal alterations are early in diabetes, preceding microvascular damages.

Cognitive impairments in theory of mind (ToM), executive processing, and decision-making are frequent and highly relevant symptoms in patients with Parkinson's disease (PD). These functions have been related to moral decision-making. Their association to moral decision-making in PD, however, has not been studied yet. It was hypothesized that moral decisions in patients with PD differ from those in healthy control participants, and that more egoistic decisions are related to ToM as well as executive dysfunctions in patients with PD. Nineteen patients with PD and 20 healthy control participants were examined with an everyday moral decision-making task, comprised of 10 low and 10 high emotional forced-choice moral dilemma short stories with egoistic and altruistic options. All participants received an elaborate neuropsychological test battery. Electrodermal skin conductance responses were recorded to examine possible unconscious emotional reactions during moral decision-making. The groups performed comparably in total scores of moral decision-making. Although ToM did not differ between groups, it was inversely related to altruistic moral decisions in the healthy control group, but not in patients with PD. Executive functions were not related to moral decision-making. No differences were found for skin conductance responses, yet they differed from zero in both groups. Our findings indicate that moral decisions do not differ between patients with PD and healthy control participants. However, different underlying processes in both groups can be presumed. While healthy control participants seem to apply ToM to permit egoistic moral decisions in low emotional dilemmas, patients with PD seem to decide independently from ToM. These mechanisms as well as neuropsychological and neurophysiological correlates are discussed.

The aim of the study was to estimate intake of total dietary fiber, and its soluble and insoluble fractions, by children with inflammatory bowel disease (IBD) in comparison with healthy controls. This was a prospective controlled study on children with IBD. Food consumption data were collected by using the 3-day diet record. For intake of soluble and insoluble fibers author's questionnaire was used. The study included 50 children with IBD (80% in clinical remission) and 50 healthy controls. There were no statistically significant differences in age, weight, height, and BMI percentiles between both groups. The mean disease duration was 3.5 ± 2.5 years. The daily median dietary fiber intake in patients was 15.3 ± 4.2 g, whereas controls consumed about 14.1 ± 3.6 g/day; differences were not statistically significant. The median intake of soluble fiber in the study group was 5.0 g/day and in controls 4.7 g/day, whereas the intake of insoluble fractions was 10.2 versus 9.7 g/day, respectively. The total fiber intake significantly increased with age and it was higher among boys in each age group. The boys better achieved adequate intake recommendations (P = 0.003). Both, children with IBD and healthy controls, did not meet the adequate intake recommendations. Intake of fiber in patients with IBD and healthy controls was comparable; however, in both groups, it was lower than recommended.

An antisaccade experiment, using happy, sad, and neutral faces, was conducted to examine the effect of mood-congruent information on inhibitory control (antisaccade task) and attentional orienting (prosaccade task) during the different episodes of bipolar disorder (BD) - manic (n=22), depressive (n=25), and euthymic (n=24). A group of 28 healthy controls was also included. Results revealed that symptomatic patients committed more antisaccade errors than healthy individuals, especially with mood-congruent faces. The manic group committed more antisaccade errors in response to happy faces, while the depressed group tended to commit more antisaccade errors in response to sad faces. Additionally, antisaccade latencies were slower in BD patients than in healthy individuals, whereas prosaccade latencies were slower in symptomatic patients. Taken together, these findings revealed the following: (a) slow inhibitory control in BD patients, regardless of their episode (i.e., a trait), and (b) impaired inhibitory control restricted to symptomatic patients (i.e., a state).

The role of laryngopharyngeal reflux (LPR) on hoarseness is widely assumed and accepted. Few articles present objective information on the subject. One of the main problems in establishing a relationship is our lack of knowledge of what is normal. We compared patients with chronic hoarseness and healthy controls to establish three goals: (1) to demonstrate the presence of additional symptoms and signs of LPR in patients with hoarseness; (2) to find the prevalence of LPR by utilizing 24 h double-probe in patients with hoarseness and compare it with that of the control group; (3) to contribute data to establish prevalence of LPR in healthy population. Forty-three patients with hoarseness and 20 healthy volunteers were enrolled in the study. All the patients in the study group had hoarseness of more than 3 months duration. The subjects recieved videolaryngoscopic evaluation and 24 h double-probe pH monitoring, and the results were compared. In the study group, 27 patients (62.8%) out of 43 had LPR episodes, compared to 6 (30%) of 20 healthy volunteers. Mean number of LPR episodes recorded by the pharyngeal probe was 7.0 [standard deviation (SD): 8.8] in 24 h, and this was significantly higher than that of the healthy controls [0.9/24 h (SD: 1.9)] (P = 0.003). Mean number of LPR episodes of the study group in upright position was 5.8 (SD: 7,0) and in supine position was 1.2 (SD: 3.3). These numbers were also significantly higher from the controls (P = 0.005 and P = 0.014 respectively). The results of this study show that: (1) most common additional symptoms were heartburn and chronic throat clearing and most common finding is pachydermia; (2) LPR incidence in patients with chronic hoarseness is significantly higher than the LPR incidence in healthy controls; (3) LPR is present in healthy people. However, the severity of LPR seems to be the causative factor rather than its presence.

Aims "Athlete's heart" is a cardiac adaptation to long-term intensive training. The aims of this study were to show the prevalence of left ventricular hypertrophy in teenagers who participate in sports, to define the different types of cardiac re-modelling, and to differentiate between physiological and pathological hypertrophy. Echocardiographic measurements were obtained by M-mode, two dimensional, and Doppler techniques of participants from sports and control groups. The echocardiographic examinations included 100 healthy teenagers taking part in dynamic sports such as football and basketball and 100 healthy teenagers taking part in static sports such as karate and judo. The control group (n=100) included healthy, sedentary teenagers. Sports participants had significantly higher left ventricular mass when compared with the control group, (p0.05). Respondents from both groups had E/A ratios (transmitral flow velocity ratio)>1, preserved diastolic function, and statistically they did not differ from the control group. Echocardiographic parameters show that physiological hypertrophy and cardiac re-modelling are present in teenagers who play sports. Unexpectedly, the prevalence of concentric and eccentric types of re-modelling is equally possible in the group of static sports participants.

The aim of our study is to examine effects of aerobic and Pilates exercises on disability, cognition, physical performance, balance, depression and fatigue in relapsing-remitting Multiple Sclerosis (MS) patients as compared to healthy controls. The subjects were divided as aerobic exercise (n = 26), Pilates (n = 9), and the healthy control group (n = 21). We used MSFC, physical performance, Berg balance scale, Beck depression scale, fatigue impact scale. All evaluations were performed before and after exercise training. There are statistically meaningful differences between Nine hole testing, PASAT 3, physical performance and fatique impact scale before and after aerobic exercise. Also we found significant difference for physical performance in the Pilates group. There are no significant differences in measures of fatique impact scale and depression between aerobic exercise group and the healthy controls after exercise. We found significant differences between Pilates and control group's after measurements except depression. There were significant differences between the Pilates and aerobic group for cognitive tests in favor of the Pilates group. Aerobic exercise and clinical Pilates exercises revealed moderate changes in levels of cognitive, physical performance, balance, depression, fatigue in MS patients.

We sought to determine whether oxidative stress and anti-oxidative activity could act as biomarkers that discriminate patients with chronic fatigue syndrome (CFS) from healthy volunteers at acute and sub-acute fatigue and resting conditions. We calculated the oxidative stress index (OSI) from reactive oxygen metabolites-derived compounds (d-ROMs) and the biological antioxidant potential (BAP). We determined changes in d-ROMs, BAP, and OSI in acute and sub-acute fatigue in two healthy groups, and compared their values at rest between patients with CFS (diagnosed by Fukuda 1994 criteria) and another group of healthy controls. Following acute fatigue in healthy controls, d-ROMs and OSI increased, and BAP decreased. Although d-ROMs and OSI were significantly higher after sub-acute fatigue, BAP did not decrease. Resting condition yielded higher d-ROMs, higher OSI, and lower BAP in patients with CFS than in healthy volunteers, but lower d-ROMs and OSI when compared with sub-acute controls. BAP values did not significantly differ between patients with CFS and controls in the sub-acute condition. However, values were significantly higher than in the resting condition for controls. Thus, measured of oxidative stress (d-ROMS) and anti-oxidative activity (BAP) might be useful for discriminating acute, sub-acute, and resting fatigue in healthy people from patients with CFS, or for evaluating fatigue levels in healthy people.

This study investigated the serum concentration of soluble CD30 (sCD30) in pregnant women with isolated fetal intrauterine growth restriction, in pregnancies complicated by preeclampsia with and without accompanying intrauterine growth restriction, and in normotensive healthy pregnant controls. Lower serum concentrations of sCD30 were observed in the group of normotensive pregnant women with a growth-restricted fetus in comparison with the group of healthy pregnant controls, and also in comparison with both preeclamptic groups of pregnant women with and without fetal growth restriction. The concentration of sCD30 in maternal serum from preeclamptic women did not differ in comparison with values from healthy controls or pregnancies complicated by isolated fetal intrauterine growth restriction.

We examined the effects of photobiomodulation (PBM) on stereological parameters, and gene expression of Runt-related transcription factor 2 (RUNX2), osteocalcin, and receptor activator of nuclear factor kappa-B ligand (RANKL) in repairing tissue of tibial bone defect in streptozotocin (STZ)-induced type 1 diabetes mellitus (TIDM) in rats during catabolic response of fracture healing. There were conflicting results regarding the efficacy of PBM on bone healing process in healthy and diabetic animals. Forty-eight rats have been distributed into four groups: group 1 (healthy control, no TIDM and no PBM), group 2 (healthy test, no TIDM and PBM), group 3 (diabetic control, TIDM and no PBM), and group 4 (diabetic test, no TIDM and PBM). TIDM was induced in the groups 3 and 4. A partial bone defect in tibia was made in all groups. The bone defects of groups second and fourth were irradiated by a laser (890 nm, 80 Hz, 1.5 J/cm 2 ). Thirty days after the surgery, all bone defects were extracted and were submitted to stereological examination and real-time polymerase chain reaction (RT-PCR). PBM significantly increased volumes of total callus, total bone, bone marrow, trabecular bone, and cortical bone, and the numbers of osteocytes and osteoblasts of callus in TIDM rats compared to those of callus in diabetic control. In addition, TIDM increased RUNX2, and osteocalcin in callus of tibial bone defect compared to healthy group. PBM significantly decreased osteocalcin gene expression in TIDM rats. PBM significantly increased many stereological parameters of bone repair in an STZ-induced TIDM during catabolic response of fracture healing. Further RT-PCR test demonstrated that bone repair was modulated in diabetic rats during catabolic response of fracture healing by significant increase in mRNA expression of RUNX2, and osteocalcin compared to healthy control rats. PBM also decreased osteocalcin mRNA expression in TIDM rats.

Working memory impairments are prevalent among patients with acquired brain injury (ABI). Computerised training targeting working memory has been researched extensively using samples from healthy populations but this field remains isolated from similar research in ABI patients. We report the results of an actively controlled randomised controlled trial in which 17 patients and 18 healthy subjects completed training on an N-back task. The healthy group had superior improvements on both training tasks (SMD = 6.1 and 3.3) whereas the ABI group improved much less (SMD = 0.5 and 1.1). Neither group demonstrated transfer to untrained tasks. We conclude that computerised training facilitates improvement of specific skills rather than high-level cognition in healthy and ABI subjects alike. The acquisition of these specific skills seems to be impaired by brain injury. The most effective use of computer-based cognitive training may be to make the task resemble the targeted behaviour(s) closely in order to exploit the stimulus-specificity of learning.

Recent studies have attempted to compare patients affected by psychogenic non-epileptic seizures (PNES) to patients affected by functional motor symptoms (FMS) from a demographic, clinical and psychological perspective. Nevertheless, results are quite controversial and significant conclusions have not been drawn. The aim of our study was to evaluate the phenomenology of psychology of the two groups assessing levels of dissociation and its subcomponents, alexithymia and interoceptive sensitivity in patients with PNES and in patients with FMS. We conducted a cross-sectional study recruiting 20 patients with PNES, 20 patients with FMS and 20 healthy subjects as a control group. All subjects underwent: Dissociative Experience Scale (DES), Somatoform Dissociation Questionnaire (SDQ-20), Cambridge Depersonalization Scale (CDS), Toronto Alexithymia Scale (TAS-20), Hamilton Rating Scale for Depression (HAM-D), Hamilton Rating Scale for anxiety (HAM-A), heart beat detection task. Our data suggest that PNES group scored significantly higher than the healthy control group on a measure of detachment (CDS). Also at the DES, a measure of psychoform dissociation, PNES patients scored significantly higher than healthy subjects. On the other hand patients affected by FMS scored significantly higher than the healthy control group on the SDQ but they did not report more experiences of detachment on the CDS. Patients affected by PNES and FMS were significantly more alexithymic than healthy controls, with a third of them scoring >61 on the TAS-20. Our data show different psychological mechanisms underlying patients with PNES and patients with FMS. This might lead also to potential implications for treatment. Copyright © 2016 Elsevier B.V.

The Hvidoere Study Group (HSG) has demonstrated major differences in glycemic control between pediatric diabetes centers which remain largely unexplained. This study investigates whether these differences are partly attributable to healthy eating norms in the background population. The study involved adolescents from 18 countries from (i) the Health Behaviour in School-Aged Children study (HBSC) and (ii) the HSG. There were 94 387 participants from representative HBSC samples of 11-, 13- and 15-yr-olds and 1483 11- to 15-yr-old adolescents with diabetes from the HSG. The frequency of intake of fruit, vegetables, sweets, sugary soft drinks, and daily breakfast was compared between the two groups. The glycemic control of the adolescents in the HSG cohort was determined by measuring glycated hemoglobin (HbA1c). Across countries in the HSBC survey, there was substantial variation in prevalence of healthy eating behavior and even greater variation between adolescents from the HSG centers. In all countries more adolescents with diabetes reported healthy eating behavior compared to national norms. In individuals healthy eating behavior had a significant effect on the individual level HbA1c. There was no significant correlation between the frequencies of these healthy eating behaviors at (i) the national level and (ii) diabetes center level and the center mean HbA1c. Although individual healthy eating behavior is associated with better glycemic control at the individual level, such eating behavior does not explain the center differences in HbA1c. Similarly, the reported healthy eating norm of the background populations does not explain the variation in glycemic control among centers. © 2013 John Wiley & Sons A/S.

Background and aim Continuation of healthy nutritional behaviors is one of the important factors in effectiveness of educational intervention programs. The aim of this research is to compare the Health Belief Model and the Ecological-social model in reducing consumption of rice contaminated with toxic metals after completion of environmental intervention and continuation of consumption of healthy rice. Methods This research was the implementation of a six-month randomized controlled trial interventional program in two groups’ interventions along with a control group, with 80 people for each group totally, amounting to 240 women, between 18 and 50 years of age in Ilam, Iran in 2014. The questionnaires of the three groups consisted of demographic information, knowledge, the constructs of the models, performance of rice consumption. Friedman test and repeated measures used for data analysis with SPSS (version 20), and confidence interval of 95% were considered. Results The results of the Friedman test indicated a significant increase in the number of women consuming healthy rice over six months after intervention in both intervention groups (p<0.001). Women in the ECO group consumed healthy rice 27.5% more than the HBM group (p<0.001). The results of repeated measures analysis of variance suggested greater improvement in the consumption of healthy rice in the ECO group in comparison with the HBM group over six months after intervention (p<0.05). Conclusions Both educational environmental intervention methods caused the altered diet of people regarding consumption of healthy rice over six months after the intervention. Increased social support also probably had a more effective role in continuation of healthy diet among the people. PMID:29588814

OBJECTIVE: To describe and quantify the morphological characteristics of nailfold capillaries that distinguish different forms of connective tissue disease from healthy controls. METHODS: A CCD video microscope with fibreoptic illumination and PC based image processing was used to visualise nailfold capillaries and to quantify findings in 23 patients with systemic sclerosis (SSc), 22 patients with systemic lupus erythematosus (SLE), 21 patients with undifferentiated connective tissue disease (UCTD), and 38 healthy controls. RESULTS: Capillary density was reduced in SSc (5.2 (SD 1.3) capillaries/mm) compared with other patient groups and controls. The average number of enlarged capillaries/finger was high in all disease groups (5.5-6.6) compared with controls (2). However, giant capillaries were most frequent in SSc (43%) and were not present in controls. Mild and moderate avascular areas were present in all groups (35%-68%), but severe avascularity was most frequent in SSc (44%) compared with other patients (18%-19%) and controls (0%). The greatest frequency of extensive haemorrhage was in SSc (35%). CONCLUSIONS: There is a range of abnormal capillary findings in patients with connective tissue disease and healthy controls. However, certain abnormalities such as a reduced number of capillaries, severe avascularity, giant capillaries, and haemorrhage are most commonly associated with SSc. Videomicroscopy with image processing offers many technical advantages that can be exploited in further studies of nailfold capillaries. Images PMID:8774177

Alzheimer's disease (AD) is a progressive neurodegenerative disorder. Current avenues of AD research focus on pre-symptomatic biomarkers that will assist with early diagnosis of AD. The majority of magnetic resonance imaging (MRI) based biomarker research to date has focused on neuronal loss in grey matter and there is a paucity of research on white matter. Longitudinal DTI data from the Alzheimer's Disease Neuroimaging Initiative 2 database were used to examine 1) the within-group microstructural white matter changes in individuals with AD and healthy controls at baseline and year one; and 2) the between-group microstructural differences in individuals with AD and healthy controls at both time points. 1) Within-group: longitudinal Tract-Based Spatial Statistics revealed that individuals with AD and healthy controls both had widespread reduced fractional anisotropy (FA) and increased mean diffusivity (MD) with changes in the hippocampal cingulum exclusive to the AD group. 2) Between-group: relative to healthy controls, individuals with AD had lower FA and higher MD in the hippocampal cingulum, as well as the corpus callosum, internal and external capsule; corona radiata; posterior thalamic radiation; superior and inferior longitudinal fasciculus; fronto-occipital fasciculus; cingulate gyri; fornix; uncinate fasciculus; and tapetum. The current results indicate that sensitivity to white matter microstructure is a promising avenue for AD biomarker research. Additional longitudinal studies on both white and grey matter are warranted to further evaluate potential clinical utility.

To explore the pathogenesis of abnormal behavior in children with obstructive sleep apnea-hypopnea syndrome (OSAHS). The behavioral problems and C-reactive protein were measured in 40 children with OSAHS and 30 children with habitual snoring who underwent overnight Polysomnography, 40 cases of healthy children for the control group. The ratio of abnormal behavior in OSAHS and habitual snoring children was significantly higher than that of the healthy control group, while no significant difference between the two groups. The content of C-reactive protein in OSAHS children (4.24 mg/L) was significantly higher than habitual snoring (2.76 mg/L) and healthy control group (1.27 mg/L); in habitual snoring children C-reactive protein was higher than in healthy control group. The content of serum C-reactive protein in OSAHS children accompanied by abnormal behavior (4.63 mg/L) was significantly higher than that without abnormal behavior (3.23 mg/L). The content of serum C-reactive protein content in habitual snoring children accompanied by abnormal behavior (3.63 mg/L) was significantly higher than that without abnormal behavior (1.76 mg/L). OSAHS and habitual snoring children have more behavior problems. C-reactive protein levels are higher in children with OSAHS and habitual snoring, and the levels of C-reactive protein are related to the abnormal behavior in these children.

Depletion of pro-inflammatory CD161(+) double negative (CD3(+)CD4(-)CD8(-)) T cells in AIDS patients is ameliorated by expansion of the γδ T cell population.

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

Difficulties in ambulation are one of the main problems reported by patients with multiple sclerosis. A previous study by our research group showed increased recruitment of muscle groups during walking, but the influence of skeletal muscle properties, such as muscle fiber activity, has not been fully elucidated. The purpose of this investigation was to use the novel method of calculating glucose uptake heterogeneity in the leg muscles of patients with multiple sclerosis and compare these results to healthy controls. Eight patients with multiple sclerosis (4 men) and 8 healthy controls (4 men) performed 15 min of treadmill walking at a comfortable self-selected speed following muscle strength tests. Participants were injected with ≈ 8 mCi of [(18)F]-fluorodeoxyglucose during walking after which positron emission tomography/computed tomography imaging was performed. No differences in muscle strength were detected between multiple sclerosis and control groups (P>0.27). Within the multiple sclerosis, group differences in muscle volume existed between the stronger and weaker legs in the vastus lateralis, semitendinosus, and semimembranosus (P<0.03). Glucose uptake heterogeneity between the groups was not different for any muscle group or individual muscle of the legs (P>0.16, P≥0.05). Patients with multiple sclerosis and healthy controls showed similar muscle fiber activity during walking. Interpretations of these results, with respect to our previous study, suggest that walking difficulties in patients with multiple sclerosis may be more associated with altered central nervous system motor patterns rather than alterations in skeletal muscle properties.

Diarrhea is a global disease with a high morbidity and mortality rate in children. In this study, 25 fecal samples were collected from children under 5 years old. Seven samples had been taken from healthy children without diarrhea and marked as the healthy control group; eight samples had been sampled from children with diarrhea caused by dyspepsia and defined as the non-infectious group; and ten samples had been taken from children with diarrhea induced by intestinal infections and identified as the infectious group. We detected the microbial communities of samples by using high-throughput sequencing of 16S rRNA genes. The proportion of aerobic and facultative anaerobic microbes in samples of the infectious group was much higher than in the non-infectious group. In addition, the relative abundance of Enterococcus in the healthy control group was significantly higher than in the non-infectious group and infectious group. This can be used as a potential diagnostic biomarker for diarrhea.

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.

Increased self-focus and negative self-concept play an important role in depression. Antidepressants influence self-referential processing in healthy volunteers, but their function in self-processing of depressed patients remains unknown. Thirty-two depressed patients were randomly allocated to receive either escitalopram 10 mg or placebo for one week. After one week, neural responses to positive and negative self-referential adjectives and neutral control stimuli were assessed with functional magnetic resonance imaging. A group of matched healthy volunteers served as a control group. Escitalopram decreased responses of medial fronto-parietal regions to self-referential words relative to non-emotional control stimuli, driven by increased responses to the control condition. Escitalopram also increased responses in the pre-defined region of the medial prefrontal cortex (MPFC) and the anterior cingulate cortex (ACC) to positive relative to negative words. Importantly, the changes in neural responses occurred before any effect on depressive symptoms, implying a direct effect of escitalopram. Furthermore, the placebo group had decreased responses of the MPFC and the ACC to positive self-referential processing relative to the matched healthy controls. However, neural responses of the escitalopram group and the healthy unmedicated controls were similar. Differences between the groups in self-reported depression symptoms and personality traits may have influenced the results. One-week treatment with escitalopram normalized aberrant self-referential processing in depressed patients, shifting the focus from the self to the external environment and potentiating positive self-referential processing. This may be an important factor in mechanism of action of antidepressants. Copyright © 2018 Elsevier B.V. All rights reserved.

Background To determine whether there is a difference between patients with low back pain and healthy controls in a test battery score for movement control of the lumbar spine. Methods This was a case control study, carried out in five outpatient physiotherapy practices in the German-speaking part of Switzerland. Twelve physiotherapists tested the ability of 210 subjects (108 patients with non-specific low back pain and 102 control subjects without back pain) to control their movements in the lumbar spine using a set of six tests. We observed the number of positive tests out of six (mean, standard deviation and 95% confidence interval of the mean). The significance of the differences between the groups was calculated with Mann-Whitney U test and p was set on <0.05. The effect size (d) between the groups was calculated and d>0.8 was considered a large difference. Results On average, patients with low back pain had 2.21(95%CI 1.94–2.48) positive tests and the healthy controls 0.75 (95%CI 0.55–0.95). The effect size was d = 1.18 (p < 0.001). There was a significant difference between acute and chronic (p < 0.01), as well as between subacute and chronic patient groups (p < 0.03), but not between acute and subacute patient groups (p > 0.7). Conclusion This is the first study demonstrating a significant difference between patients with low back pain and subjects without back pain regarding their ability to actively control the movements of the low back. The effect size between patients with low back pain and healthy controls in movement control is large. PMID:19108735

Despite strong empirical support for the association between perceived food affordability and dietary intake amongst families with a lower socioeconomic position (SEP), there is limited evidence of the most effective strategies for promoting more positive perceptions of healthy food affordability among this group. This paper reports findings from a pilot intervention that aimed to improve perceptions of healthy food affordability amongst mothers. Participants were 66 mothers who were the parents of children recruited from primary schools located in socioeconomically disadvantaged suburbs. Intervention group participants viewed a slideshow focussed on healthy snack food affordability that illustrated cheaper healthier alternatives to common snack foods as well as food budgeting tips and price comparison education. A mixed between-within ANCOVA was conducted to examine group differences in perceived affordability of healthy food across three time points. Results revealed no difference in perceived affordability of healthy food between the two groups at baseline whereas at post-intervention and follow-up, mothers in the intervention group perceived healthy food as more affordable than the control group. Focussing on education-based interventions to improve perceptions of healthy food affordability may be a promising approach that complements existing nutrition promotion strategies.

The study of neurological soft signs (NSS) in patients with Asperger syndrome may help us to elucidate the neurological basis of this disorder and to clarify its relationship with other neurodevelopmental disorders. The goal of this study was to compare the prevalence of NSS in a sample of patients with Asperger syndrome, early-onset psychosis and healthy controls. NSS were assessed by means of the Neurological Evaluation Scale in a sample of 29 patients with Asperger syndrome (mean age = 12.86 ± 2.58 years), 30 patients with first-episode early-onset psychoses (mean age 14.17 ± 1.02 years) and 30 healthy controls (mean age 12.33 ± 2.69 years). Significant group differences were found between Asperger syndrome patients and healthy controls both in all the Neurological Evaluation Scale subscales and in the Neurological Evaluation Scale total score. There were no significant differences between both groups of patients in any of the Neurological Evaluation Scale scores. NSS are more prevalent in Asperger syndrome than in healthy controls. The NSS profile was not disorder-specific in our samples of patients with Asperger syndrome and early-onset psychoses. © 2010 Blackwell Publishing Asia Pty Ltd.

To investigate the effect of granulocyte-colony stimulating factor (G-CSF) in vitro stimulation on the distribution of lymphocyte subset in healthy human. Peripheral blood mononuclear cells (PBMNCs) were collected from 8 healthy volunteers by density gradient centrifugation on Ficoll-Paque TM . In vitro 200 ng/ml G-CSF or 200 ng/ml G-CSF plus 10 µg/ml ConA directly act on PBMNCs, then the colleted cells were cultivated for 3 days. Lymphocyte subsets were stained with the corresponding fluoresce labeled antibodies and detected by flow cytometry. The levels of T cells in G-CSF group and G-CSF+ConA group were both higher than that in the control group (P<0.001, P<0.05). However, there were not significantly different in B cells and NK cells levels among the 3 groups. Furthermore, analysis of the effect of G-CSF on T cell subsets indicated that the levels of CD4 + T cells and CD8 + T cells in G-CSF group were both significantly higher than those in control group (P<0.01, P<0.05), Treg cells was not different between G-CSF and control group. Compared with the control group, the level of CD4 + T cells, CD8 + T cells and Treg cells in G-CSF+ConA group significantly increased (P<0.05, P<0.01, P<0.01). Analysis of G-CSF receptor (G-CSFR) expression showed that G-CSFR expression on T cells in G-CSF+ConA group dramatically increased, as compared with control group (P<0.01). The levels of CD4 + T cells and CD8 + T cells in healthy human peripheral blood can be increased by G-CSF stimulation. ConA can enhance the level of T cells and induce G-CSFR expression on T cells.

Childhood abuse is associated with abnormalities in brain structure and function. Few studies have investigated abuse-related brain abnormalities in medication-naïve, drug-free youth that also controlled for psychiatric comorbidities by inclusion of a psychiatric control group, which is crucial to disentangle the effects of abuse from those associated with the psychiatric conditions. Cortical volume (CV), cortical thickness (CT) and surface area (SA) were measured in 22 age- and gender-matched medication-naïve youth (aged 13-20) exposed to childhood abuse, 19 psychiatric controls matched for psychiatric diagnoses and 27 healthy controls. Both region-of-interest (ROI) and whole-brain analyses were conducted. For the ROI analysis, the childhood abuse group compared with healthy controls only, had significantly reduced CV in bilateral cerebellum and reduced CT in left insula and right lateral orbitofrontal cortex (OFC). At the whole-brain level, relative to healthy controls, the childhood abuse group showed significantly reduced CV in left lingual, pericalcarine, precuneus and superior parietal gyri, and reduced CT in left pre-/postcentral and paracentral regions, which furthermore correlated with greater abuse severity. They also had increased CV in left inferior and middle temporal gyri relative to healthy controls. Abnormalities in the precuneus, temporal and precentral regions were abuse-specific relative to psychiatric controls, albeit at a more lenient level. Groups did not differ in SA. Childhood abuse is associated with widespread structural abnormalities in OFC-insular, cerebellar, occipital, parietal and temporal regions, which likely underlie the abnormal affective, motivational and cognitive functions typically observed in this population.

to compare early discharge with home care versus standard postpartum care in terms of mothers' sense of security; contact between mother, newborn and partner; emotions towards breast feeding; and breast-feeding duration at one and three months after birth. retrospective case-control study. a labour ward unit in Stockholm, Sweden handling both normal and complicated births. 96 women with single, uncomplicated pregnancies and births, and their healthy newborns. early discharge at 12-24 hours post partum with 2-3 home visits during the first week after birth. The intervention group consisted of women who had a normal vaginal birth (n=45). This group was compared with healthy controls who received standard postnatal care at the hospital (n=51). mothers' sense of security was measured using the Parents' Postnatal Sense of Security Scale. Contact between mother, child and father, and emotions towards breast feeding were measured using the Alliance Scale, and breast-feeding rates at one and three months post partum were recorded. women in the intervention group reported a greater sense of security in the first postnatal week but had more negative emotions towards breast feeding compared with the control group. At three months post partum, 74% of the newborns in the intervention group were fully breast fed versus 93% in the control group (p=0.021). Contact between the mother, newborn and partner did not differ between the groups. early discharge with home care is a feasible option for healthy women and newborns, but randomised controlled studies are needed to investigate the effects of home care on breast-feeding rates.

Detection of cancer at the early stage is of utmost importance to decrease the morbidity and mortality of the disease. Apart from the conventional biopsy, minimally invasive methods like serum evaluation are used for screening large populations. Thus, this study aimed to estimate serum levels of sialic acid and fucose and their ratio in oral cancer patients and in healthy control group to evaluate their role in diagnosis. Serum samples were collected from 52 healthy controls (group I) and 52 squamous cell carcinoma patients (group II). Estimation of serum levels of sialic acid and fucose and their ratio was performed. This was correlated histopathologically with the grades of carcinoma. Statistical analysis was done by using analysis of variance (ANOVA) test and unpaired "t" test. Results showed that serum levels of sialic acid and fucose were significantly higher in oral cancer patients compared to normal healthy controls (P < 0.001). The sialic acid to fucose ratio was significantly lower in cancer patients than in normal controls (P < 0.01). However, comparison with histological grading, habits, gender, and age group did not show any significant result. The mean serum sialic acid and fucose levels showed an increasing trend from controls to malignant group and their corresponding ratio showed decreasing trend from controls to malignant group. The ratio of sialic acid to fucose can be a useful diagnostic aid for oral cancer patients.

We examined a behavioral mechanism of how increases in leg strength improve healthy old adults’ gait speed. Leg press strength training improved maximal leg press load 40% (p = 0.001) and isometric strength in 5 group of leg muscles 32% (p = 0.001) in a randomly allocated intervention group of healthy old adults (age 74, n = 15) but not in no-exercise control group (age 74, n = 8). Gait speed increased similarly in the training (9.9%) and control (8.6%) groups (time main effect, p = 0.001). However, in the training group only, in line with the concept of biomechanical plasticity of aging gait, hip extensors and ankle plantarflexors became the only significant predictors of self-selected and maximal gait speed. The study provides the first behavioral evidence regarding a mechanism of how increases in leg strength improve healthy old adults’ gait speed. PMID:25310220

To compare the retinal nerve fiber layer (RNFL) as well as the macula volume and thickness in the eyes of age-matched healthy controls with no cognitive disabilities with those of elderly people with mild cognitive impairment (MCI) or Alzheimer disease (AD). We used optical coherence tomography (OCT) to determine the effectiveness of the above quantities for early diagnosis of MCI or AD. Ninety eyes were considered in this study, split between 30 normal eyes, 30 eyes from patients with MCI, and 30eyes from patients with AD. All subjects underwent ophthalmologic and cognitive examinations, and measurements of the RNFL thickness as well as macular volume and thickness were taken for all patients using OCT. The mean RNFL thickness upon OCT was significantly thinner in the AD group than in the MCI group (p = 0.01). The RNFL was thinner in the superior quadrant in patients with AD when compared to the healthy controls (p = 0.03). The RNFL thicknesses in the inferior, nasal, and temporal quadrants did not differ significantly between the groups. Measurements in the 12 clock-hour zones revealed that zone 11 had a significantly thinner RNFL in the AD group as compared with the healthy control group (p = 0.02). In zone 2, the MCI group had a significantly thinner RNFL than the AD group (p = 0.03). Our OCT findings revealed a neuroanatomic difference in the RNFL thickness among the three groups, i.e., the AD, MCI, and healthy control groups. This suggests that a change in average RNFL thickness could be a meaningful index for diagnosing early AD. © 2017 The Korean Ophthalmological Society

The effects of musical training on the body in professional musicians remain an understudied area, particularly in reference to understanding and managing orthopedic/neuromuscular deviations and injuries in this population. The purpose of this study was to evaluate hand/finger fine motor function in musicians via physical examination as well as laboratory-based evaluations. Thirteen healthy noninjured young elite string musicians participated in this study. Performance of musicians was compared with healthy age-matched, sex-matched, and handedness-matched nonmusician controls. Musicians exhibited decreased intrinsic muscle strength compared with controls; however, no change in extrinsic muscle strength was found between groups. No between-group differences in overall force control were found; however, Group × Hand (right vs left) interactions were found in force control. These data suggest that musicians are a unique population with respect to: (1) fine motor control of the hand; and (2) exhibit changes in differential hand use. This suggests cortical reorganization of string musicians, such that this population should be studied separately from typical healthy controls with respect to hand function.

[Purpose] Exercise is one of the most important components of a healthy life. The purpose of this study was to analyze exercise beliefs and psychosocial factors in sedentary and active healthy women and observe the changes in these parameters resulting from clinical Pilates exercises and verbal education in healthy women. [Subjects and Methods] Sixty-six healthy women were included in the study. Participants were divided into clinical Pilates (n=21), verbal education (n=25), and control groups (n=20). Prior to and at the end of the study, demographic information, body mass index, waist-hip circumference, exercise beliefs, physical activity index, and psychosocial factors (Rosenberg self-esteem scale, Body Cathexis Index, SF-36 quality of life, Beck Depression Scale, visual analog scale for tiredness) of the subjects were recorded. [Results] Meaningful changes for all the parameters took place in the clinical Pilates and verbal education groups. Our analyses indicated that the changes in the clinical Pilates group were more meaningful than those in the verbal education group. When the data of the study groups were compared with those of the control group, the clinical Pilates group showed meaningful differences. [Conclusion] The result of this study indicate that both clinical Pilates and verbal education are effective in changing exercise beliefs and physical and psychosocial parameters.

Recent diffusion tensor imaging (DTI) studies suggest that altered white matter fiber integrity is a pathophysiological feature of schizophrenia. Lower white matter integrity is associated with poor cognitive control, a characteristic of schizophrenia that can be measured using antisaccade tasks. Although the functional neural correlates of poor antisaccade performance have been well documented, fewer studies have investigated the extent to which white matter fibers connecting the functional nodes of this network contribute to antisaccade performance. The aim of the present study was to assess the white matter structural integrity of fibers connecting two functional nodes (putamen and medial frontal eye fields) of the saccadic eye movement network implicated in poor antisaccade performance in schizophrenia. To evaluate white matter integrity, DTI was acquired on subjects with schizophrenia and two comparison groups: (a) behaviorally matched healthy comparison subjects with low levels of cognitive control (LCC group), and (b) healthy subjects with high levels of cognitive control (HCC group). White matter fibers were tracked between functional regions of interest generated from antisaccade fMRI activation maps, and measures of diffusivity were quantified. The results demonstrated lower white matter integrity in the schizophrenia group than in the HCC group, but not the LCC group who showed similarly poor cognitive control performance. Overall, the results suggest that these alterations are not specific to the disease process of schizophrenia, but may rather be a function of uncontrolled cognitive factors that are concomitant with the disease but also observed in some healthy people. © 2017 Society for Psychophysiological Research.

In children diagnosed with celiac disease, fat soluble vitamin levels were aimed to be evaluated and it was intended to determine whether fat soluble vitamin levels were needed to be assessed routinely in these patients during diagnosis. Between May 2015-May 2016, diagnosis symptoms of celiac patients (CD) in newly diagnosed pediatric group were questioned, fat soluble vitamin levels simultaneous with intestinal biopsies were evaluated. Vitamin levels were compared with those of healthy control group. A total of 52 patients involving 27 female (51.9%), 25 male (48.1%); and a total of 50 healthy control group including 25 female (50%), 25 male (50%) were evaluated. The average age of patients was 9 ± 4.3 years, and their average weight was determined as 16.2 ± 6.3 kg. Growth retardation was the most frequent symptom in our patients (61.5%). Abdominal pain (51.9%) and diarrhea (11.5%) are among the other most commonly seen symptoms. In the histological examination of patients, Marsh 3B n = 23 (45.1%) was mostly established. Vitamin A and vitamin D levels of patients were determined significantly lower compared to those of control group. Vitamin A and vitamin D deficiencies were identified significantly higher compared to those of healthy control group. Vitamin D insufficiency was observed in 48 patients (92.3%) and vitamin D deficiency was determined in 32 (61.5%) out of 48. Vitamin A deficiency was established in 17 (32.7%) patients. Vitamin E and vitamin K1 deficiency were determined in no patients. In the healthy control group, vitamin D deficiency was seen in 2 (4%) patients, vitamin D insufficiency was determined in 9 (18%) patients. Other vitamin levels were identified at normal levels in the healthy group. In newly diagnosed children with CD, a significant lowness was established in vitamin D and A. The evaluation of vitamin A and D levels will be helpful in the course of diagnosis in these patients.

Oxidative stress resulting from dietary, lifestyle and environmental factors is strongly associated with tissue damage and aging. It occurs when there is either an overproduction of reactive oxygen species (i.e., oxidants) or decreased bioavailability of antioxidants that can scavenge them. The objective of this 12-week double-blind placebo-controlled study was to assess the efficacy of a nutraceutical at augmenting antioxidant status. Healthy adults (25-45 y) were randomized to either a treatment group (Product B, n = 23) or a placebo group (control, n = 20). No significant effect of Product B was observed for anthropometric variables or markers of glucose and lipid regulation. Biomarkers of oxidative stress were likewise not altered following the 12-week intervention. Plasma catalase concentrations were significantly elevated following 12 weeks of Product B as compared to the control group (+6.1 vs. -10.3 nmol/min/mL, p = 0.038), whereas other measures of antioxidant capacity were not significantly different between the groups. Product B effectively augmented concentrations of the anti-aging antioxidant catalase in healthy adults.

The purpose of this article is to describe the study design, protocol, and baseline results of the "Healthy Habits, Healthy Girls" program. The intervention is being evaluated through a randomized controlled trial in 10 public schools in the city of São Paulo, Brazil. Data on the following variables were collected and assessed at baseline and will be reevaluated at 7 and 12 months: body mass index, waist circumference, dietary intake, nutrition, physical activity, social cognitive mediators, physical activity level, sedentary behaviors, self-rated physical status, and overall self-esteem. According to the baseline results, 32.4% and 23.4% of girls were overweight in the intervention and control groups, respectively, and in both groups a higher percentage failed to meet daily recommendations for moderate and vigorous physical activity and maximum screen time (TV, computer, mobile devices). There were no significant differences between the groups for most of the variables, except age (p = 0.000) and waist circumference (p = 0.014). The study showed a gap in the Brazilian literature on protocols for randomized controlled trials to prevent obesity among youth. The current study may thus be an important initial contribution to the field.

Our study group previously measured pituitary volumes and found a relationship between somatoform disoders and pituitary volumes. Therefore, in conversion disorder, another somatoform disorder, we hypothesized that pituitary gland volumes would be reduced. Twenty female patients and healthy controls were recruited to the present investigation. The volumes of the pituitary gland were determined by using a 1.5 Tesla magnetic resonance scanner. We found that the pituitary gland volumes of the patients with conversion disorder were significantly smaller than those of healthy control subjects. In the patients with conversion disorder but not in the healthy control group, a significant negative correlation between the duration of illness and pituitary gland volume was determined. In summary, in the present study, we suggest that the patients with conversion disorder have smaller pituitary volumes compared to those of healthy control subjects. Further studies should confirm our data and ascertain whether volumetric alterations determined in the patients with conversion disorder can be changed with treatment or if they change over time.

Abnormal prefrontal function plays a central role in the cognition deficits of schizophrenic patients; however, the character of the relationship between discriminant analysis and prefrontal activation remains undetermined. Recently, evidence of low prefrontal cortex (PFC) activation in individuals with schizophrenia has also been found during verbal fluency tests (VFT) and other cognitive tests with several neuroimaging methods. The purpose of this study is to assess the hemodynamic changes of the PFC and discriminant analysis between schizophrenia patients and healthy controls during VFT task by utilizing functional optical topography. A total of 99 subjects including 53 schizophrenic patients and 46 age- and gender-matched healthy controls were studied. The results showed that the healthy group had larger activation in the right and left PFC than in the middle PFC. Besides, the schizophrenic group showed weaker task performance and lower activation in the whole PFC than the healthy group. The result of the discriminant analysis showed a significant difference with P value <0.001 in six channels (CH 23, 29, 31, 40, 42, 52) between the schizophrenic and healthy groups. Finally, 68.69% and 71.72% of subjects are correctly classified as being schizophrenic or healthy with all 52 channels and six significantly different channels, respectively. Our findings suggest that the left PFC can be a feature region for discriminant analysis of schizophrenic diagnosis.

Probing Implicit Learning in Obsessive-Compulsive Disorder: Moderating Role of Medication on the Weather Prediction Task

2016-01-01

Deficits in implicit learning, a process by which knowledge is acquired accretively through practice independent of conscious awareness, have been implicated in Obsessive-Compulsive Disorder (OCD). The weather-prediction task (WPT) was used to assess implicit learning in 26 unmedicated patients with OCD and 23 healthy controls. An additional analysis compared these two groups with 25 medicated patients with OCD. In the comparison of unmedicated patients with healthy controls there was a subtle but statistically significant group-by-block interaction. Patients with OCD showed slower improvement in performance during the middle phase of learning. In a three-group comparison, there was no main effect of group; in post-hoc tests, medicated patients with OCD differed from unmedicated patients and were not different from healthy controls. Unmedicated patients with OCD have a subtle deficit in implicit learning in the WPT. This may be mitigated by pharmacotherapy, although prospective studies would be required to confirm this conclusion. PMID:27134820

Nocturnal motor activity in fibromyalgia patients with poor sleep quality.

1995-01-01

Nocturnal motor activity was examined in long-term rehabilitation patients complaining of poor sleep and having fibromyalgia syndrome (N = 24) or other musculoskeletal disorders (N = 60) and compared with that in 91 healthy controls drawn from a random community sample. Self-reports on sleep complaints and habits were collected. The frequency of nocturnal body movements, the "apnoea" index and ratio of "quiet sleep" to total time in bed were measured using the Static Charge Sensitive Bed (SCSB) (BioMatt). As a group, patients with fibromyalgia syndrome did not differ from patients with other musculoskeletal disorders or from healthy controls in their nocturnal motor activity. The "apnoea" index was a little higher in the fibromyalgia group than in the healthy control group but did not differ from that of the group of other musculoskeletal patients. Further multivariate analyses adjusted for age, BMI, medication and "apnoea" index did not support the assumption that an increased nocturnal motor activity characterizes patients with fibromyalgia syndrome.

The aim of this study was to evaluate the serum concentrations of rheumatoid factor and anti-nuclear antibodies in H. pylori-infected peptic ulcer patients, H. pylori-infected asymptomatic carriers and a healthy control group. A Total of 100 H. pylori-infected peptic ulcer patients, 65 asymptomatic carriers and 30 healthy H. pylori-negative subjects (as a control group) were enrolled into study. Serum samples of participants tested for the levels of rheumatoid factor and anti-nuclear antibodies by use of ELISA. The mean serum levels of rheumatoid factor and anti-nuclear antibodies in peptic ulcer group was significantly higher in comparison to the control group (p<0.05). Although, the mean serum levels of rheumatoid factor and anti-nuclear antibodies in the asymptomatic carriers group was higher than those in the control group, the difference was not statistically significant. No significant differences were observed between peptic ulcer patients and asymptomatic carriers groups regarding the mean serum levels of rheumatoid factor and anti-nuclear antibodies. The mean serum levels of rheumatoid factor in men with peptic ulcer was significantly higher compared to the group of healthy men (p<0.05). Although in female of peptic ulcer patients or asymptomatic carriers groups, the mean serum levels of rheumatoid factor was higher than that in healthy women, but the differences were not statistically significant. Also, no significant differences were observed between men and women with peptic ulcer, asymptomatic carriers control groups based on the serum levels of anti-nuclear antibodies. The results showed higher serum levels of rheumatoid factor and anti-nuclear antibodies in H. pylori-infected patients with peptic ulcer disease which represent the H. pylori-related immune disturbance in these patients. Additional follow-up studies are necessary to clarify the clinical significance of these autoantibodies in patients with H. pylori infection.

Previous cross-diagnosis studies of interaction between mothers with severe mental illness and their babies have concluded that mothers with schizophrenia have deficits in interaction, but these studies have not included healthy controls. In-patients on a mother and baby unit, with diagnoses of schizophrenia (n=15), depressive mood disorders with or without psychosis (n=23), or mood disorders where mania was the predominant feature, with or without psychosis (n=12), were observed interacting with their infants on admission and discharge. Mothers' mind-mindedness and other measures of the quality of maternal and infant behaviour were coded. Findings from this sample were compared with those from healthy mothers and their infants (n=49). Compared with healthy controls, on admission depressed mothers were marginally less likely to comment appropriately on their infants' mental states. Both the depressed and mania groups were more likely to touch their babies and engage in attention-seeking behaviours. Interactional behaviours of mothers in the schizophrenia group were not markedly different from healthy controls. On discharge there were fewer differences between the clinical and healthy groups, although the depressed group continued to engage in more attention-seeking and touching behaviour and the mania group continued to touch their infants more. Only mothers in the schizophrenia group showed changes in interactional behaviours between admission and discharge, talking more to their infants. The findings challenge previous conclusions that mothers with schizophrenia have deficits in their interactions with their babies, and demonstrate that mothers with severe mental illness are able to respond appropriately to their infants' cues.

Individuals with knee OA often exhibit greater co-contraction of antagonistic muscle groups surrounding the affected joint which may lead to increases in dynamic joint stiffness. These detrimental changes in the symptomatic limb may also exist in the contralateral limb, thus contributing to its risk of developing knee osteoarthritis. The purpose of this study is to investigate the interlimb symmetry of dynamic knee joint stiffness and muscular co-contraction in knee osteoarthritis. Muscular co-contraction and dynamic knee joint stiffness were assessed in 17 subjects with mild to moderate unilateral medial compartment knee osteoarthritis and 17 healthy control subjects while walking at a controlled speed (1.0m/s). Paired and independent t-tests determined whether significant differences exist between groups (p<0.05). There were no significant differences in dynamic joint stiffness or co-contraction between the OA symptomatic and OA contralateral group (p=0.247, p=0.874, respectively) or between the OA contralateral and healthy group (p=0.635, p=0.078, respectively). There was no significant difference in stiffness between the OA symptomatic and healthy group (p=0.600); however, there was a slight trend toward enhanced co-contraction in the symptomatic knees compared to the healthy group (p=0.051). Subjects with mild to moderate knee osteoarthritis maintain symmetric control strategies during gait. Copyright © 2014 Elsevier Ltd. All rights reserved.

Physiological changes and immunological modifications occur during pregnancy. The clinical and biological features of periodontal infections are affected by pregnancy. The aim of the present study was to evaluate saliva levels of 25-hydroxy-vitamin D3 (25(OH)D3), prostaglandin E2 (PGE2) and TNF-alpha (TNF-α) in pregnancy, postpartum and non-pregnant controls. Whole saliva samples together with full-mouth clinical periodontal recordings were obtained from 59 pregnant, 47 post partum and 70 systemically healthy non-pregnant women. Groups were also evaluated according to the periodontal health status. 25(OH)D3, PGE2 and TNF-α levels in the saliva samples were determined by enzyme-linked immunoassays. Data were statistically tested by nonparametrical tests. Saliva TNF-α and PGE2 levels were significantly lower and 25(OH)D3 levels were significantly higher in the pregnant group than postpartum group (p<0.0001). Saliva TNF-α and 25(OH)D3 levels were significantly higher and PGE2 levels were significantly lower in the control group than postpartum group (p<0.0001). In the pregnant healthy, gingivitis and periodontitis groups saliva TNF-α levels were significantly lower than postpartum and control counterparts (p<0.0001, p=0.032, p=0.003 and p=0.013; p=0.027; p=0.007, respectively). In control healthy, gingivitis and periodontitis groups saliva 25(OH)D3 levels were significantly higher than the postpartum counterparts (p<0.0001, p<0.0001, p=0.002, respectively). In the control healthy and gingivitis groups saliva 25(OH)D3 levels were significantly higher than pregnant healthy and gingivitis (p<0.0001). In conclusion, within the limits of the present study it seems that pregnancy have an effect on parameters in saliva in relation to the periodontal status of the women. Further studies are required for better understanding of the impact of periodontal diseases on pregnancy or otherwise. Copyright © 2015 Elsevier Ltd. All rights reserved.

Alpha BRAIN® is a nootropic supplement that purports to enhance cognitive functioning in healthy adults. The goal of this study was to investigate the efficacy of this self-described cognitive enhancing nootropic on cognitive functioning in a group of healthy adults by utilizing a randomized, double blind, placebo-controlled design. A total of 63-treatment naïve individuals between 18 and 35 years of age completed the randomized, double-blind, placebo controlled trial. All participants completed a 2-week placebo run in before receiving active product, Alpha BRAIN® or new placebo, for 6 weeks. Participants undertook a battery of neuropsychological tests at randomization and at study completion. Primary outcome measures included a battery of neuropsychological tests and measures of sleep. Compared with placebo, Alpha BRAIN® significantly improved on tasks of delayed verbal recall and executive functioning. Results also indicated significant time-by-group interaction in delayed verbal recall for the Alpha BRAIN® group. The use of Alpha BRAIN® for 6 weeks significantly improved recent verbal memory when compared with controls, in a group of healthy adults. While the outcome of the study is encouraging, this is the first randomized controlled trial of Alpha BRAIN®, and the results merit further study. Copyright © 2016 John Wiley & Sons, Ltd.

The aim of the study was to analyze the differences in the activity of beta-glucuronidase and beta-glucosidase in stool specimens of children with Inflammatory Bowel Diseases (IBD) and healthy subjects. The disease activity was determined according to the PCDAI scale (Crohn disease) and Truelove-Witts scale (Ulcerative colitis). Enzyme activity was determined by spectrophotometry. There was a correlation between the level of beta - glucosidase activity in stool and patient's age in the group of healthy controls, but not in the IBD group. beta-glucosidase activity in IBD and healthy subjects stool specimens did not differ significantly. The activity of beta-glucuronidase in children with IBD was two times lower than in the healthy group and was correlated with age in children with IBD, but not in the group of healthy ones.

To bring forward the arguments for active treatment of urine incontinence in otherwise healthy children, a quality-of-life (QoL) study was performed. A self-rating QoL questionnaire, child-adjusted and validated, was completed by 120 neurologically healthy children, aged 6-16 y, with urinary incontinence. Another 239 age-matched children made up a control group. The two groups were compared both totally and in age-related subgroups (6-8, 9-12, >12 y) concerning the index for all questions, for universal parts (without questions dealing with incontinence) as well as for specific key domains. The patient group had a significantly lower index than the control group both with and without items related to incontinence (p<0.0001). Social situation, self-esteem and self-confidence were most influenced, particularly in the youngest children. Thirty-one children (13%) of the control group reported incontinence and did not score their QoL as good as their continent peers but better than the study patients. From the quality-of-life aspects, the study supports active treatment of urinary incontinence in children already at younger ages.

This study examined the effect of aromatherapy-massage in healthy postpartum mothers. A quasi-experimental between-groups design was used. Mothers who received aromatherapy-massage were compared with a control group who received standard postpartum care. Thirty-six healthy, first-time mothers with vaginal delivery of a full-term, healthy infant participated in this study. Sixteen mothers received a 30-minute aromatherapy-massage on the second postpartum day; 20 mothers were in the control group. All mothers completed the following four standardized questionnaires before and after the intervention: 1) Maternity Blues Scale; 2) State-Trait Anxiety Inventory; 3) Profile of Mood States (POMS); and 4) Feeling toward Baby Scale. In the aromatherapy-massage group, posttreatment scores significantly decreased for the Maternity Blues Scale, the State-Anxiety Inventory, and all but one of the Profile of Mood States subscales. Posttreatment scores in the intervention group significantly increased in Profile of Mood States-Vigor subscale and the Approach Feeling toward Baby subscale. Scores in the intervention group significantly decreased in Conflict Index of Avoidance/Approach Feeling toward Baby subscale. Our results suggest that aromatherapy-massage might be an effective intervention for postpartum mothers to improve physical and mental status and to facilitate mother-infant interaction.

Several prospective studies into the effects of adjuvant systemic therapy on cognitive functioning suggest that a proportion of breast cancer patients show cognitive deficits already before the start of systemic therapy. Owing to, among others, methodological inconsistency, studies report different rates of this pre-treatment cognitive impairment. We examined the impact of four different criteria of cognitive impairment and two types of reference groups (a study-specific healthy reference group versus published normative data) on the prevalence of cognitive impairment. Two hundred and five postmenopausal breast cancer patients underwent a battery of neuropsychological tests before the start of endocrine therapy, 124 healthy subjects underwent the same tests. Proportions of cognitive impaired patients were calculated for each of four criteria for cognitive impairment, using (1) study-specific healthy controls and (2) published norms of healthy controls as reference groups. The prevalence of cognitive impairment varied greatly with the strictness of the criterion, as expected, but also was dependent on the reference group used. Cognitive impairment, relative to published norms, ranged from 1% for the strictest to 36.6% for the less strict criterion, cognitive impairment relative to study-specific healthy controls, ranged from 13.7 to 45.4% for the same criteria. This study highlights contrasting proportions of cognitive impairment by using different criteria for cognitive impairment and different reference groups. (Dis)advantages of the methods using a criterion for cognitive impairment, and of the use of published norms versus a study-specific reference group are discussed.

Nonalcoholic fatty liver disease (NAFLD) is emerging as the most common liver disease. The only effective treatment is 7%-10% weight loss. Mobile technology is increasingly used in weight management. This study was performed to evaluate the effects of text messaging intervention on weight loss in patients with NAFLD. Thirty well-defined NAFLD patients (mean age 52 years, 67% females, mean BMI 38) were randomized 1:1 to control group: counselling on healthy diet and exercise, or intervention group: text messages in addition to healthy life style counselling. NAFLD text messaging program sent weekly messages for 22 weeks on healthy life style education. Primary outcome was change in weight. Secondary outcomes were changes in liver enzymes and lipid profile. Intervention group lost an average of 6.9 lbs. (P = .03) compared to gain of 1.8 lbs. in the control group (P = .45). Intervention group also showed a decrease in ALT level (-12.5 IU/L, P = .035) and improvement in serum triglycerides (-28 mg/dL, P = .048). There were no changes in the control group on serum ALT level (-6.1 IU/L, P = .46) and on serum triglycerides (-20.3 mg/dL P = .27). Using one-way analysis of variance, change in outcomes in intervention group compared to control group was significant for weight (P = .02) and BMI (P = .02). Text messaging on healthy life style is associated with reduction in weight in NAFLD patients. Larger studies are suggested to examine benefits on liver histology, and assess long-term impact of this approach in patients with NAFLD. © 2017 John Wiley & Sons A/S.

Health education is one of the primary tools for health promotion, especially for those that will be responsible for educating on healthy habits in the future. To improve healthy lifestyle habits in university students through an educational intervention based on gamification. A cuasiexperimental design of two groups (i.e., experimental groups and control group) with pretest and postest measurements was carried out. A 4-month intervention was implemented in 148 students from the Physical Activity and Sport Sciences university degree. Habits related to diet and physical activity were evaluated using a questionnaire (scaled from -40 a +50) and the teaching-learning process through a qualitative analysis. At the end of the intervention, a very significant improvement was found in the global value of the healthy lifestyle habits of the experimental group (+13,5), highlighting the improvement obtained in its higher level of compliance in the breakfast (53,4%), in the number of diary meals (31,5%), in the reduction of the consumption of soft-drinks (19,2%) and in the increase of physical activity level, with an improvement of 12,3% of participants with respect to the baseline levels. On the other hand, no significant improvements were found in the control group. An educational intervention based on gamification improves healthy lifestyle habits of the students.

The purpose of the study is to describe sleep habits, assess the prevalence of sleep disturbances in pediatric cancer patients and healthy controls, and to compare sleep patterns, sleep problems. One hundred-thirty-five patients and 190 healthy controls were evaluated. Healthy children matched for age, sex, economic status, parental education and family structure constituted the control group. Sleep was evaluated by using the Children`s Sleep Habits Questionnaire (CSHQ). Sleep problems were detected in half of patients. There were no significant differences in total sleep score and subscale scores between patients and controls. Solely the wake-time was found significantly different between patients and controls. Although our results indicated that neither childhood cancer survivors nor patients with cancer during treatment period had more sleep problems than their healthy peers, sleep problems were not uncommon in whole study group. This study underlines the need to screen, assess and manage sleep problems in children with diagnosis of cancer.

To investigate the characterizations of genetic recombination hotspots and linkage disequilibrium (LD) patterns in peroxisome proliferative activated receptor gamma (PPARG) gene in Kirgiz and Uyghur ethnic groups. Blood samples were collected from 100 Kirgiz (50 healthy controls and 50 patients with type 2 diabetes mellitus) residents in Halajun County, Artux City, Kizilsu Kirgiz Autonomous Prefecture, Xinjiang in August 2013, and 50 healthy Uyghur residents in Hotan Prefecture of Xinjiang Uygur Autonomous Region in May 2012.Thirty-one tagSNPs in PPARG gene were genotyped using Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI-TOF-MS) method.The recombination hotspots and LD patterns within the PPARG gene were estimated by analyzing the SNP genotying data using the Hotspot Fisher program and Haploview software, respectively. Eighteen tagSNPs (rs1151999, rs1175540, rs1875796, rs1899951, rs2292101, rs2921190, rs2938397, rs2959272, rs2959273, rs2972162, rs3856806, rs4135247, rs4135275, rs709151, rs4135354, rs6805419, rs17036700 and rs4135304) were same with relatively higher recombination rates between the patients with type 2 diabetes mellitus (T2DM) and healthy controls of Kirgiz ethnic group, and healthy controls of Uyghur ethnic group.Five haplotype blocks with LD coefficient D' value of 1, indicating no genetic recombination occurred within the region, were observed in the healthy controls of Kirgiz ethnic groups, whereas five haplotype blocks with LD coefficient D' value less than 1 were observed in the Kirgiz patients with T2DM, indicating historical recombination events occurred within the region.Four haplotype blocks with LD coefficient D' value of 1 were observed in the Uyghur healthy controls, indicating no genetic recombination occurred within the region.There were significantly different recombination hotspot profiles between the Kirgiz, Uyghur, Utah residents with Northern and Western European ancestry (CEU), Yoruban in Ibadan, Nigeria (YRI) and Han Chinese in Beijing (CHB) and Japanese in Tokyo (JPT) samples.There are six recombination hotspots in the HapMap profile of genetic recombination.The last 5 SNPs within the PPARG gene were shown with lower recombination rates in the Kirgiz, whereas no recombination hotspot was found in the Uyghur. Variable recombination rates may be present in certain chromosome region between patients and healthy controls within the same or between the different ethnic groups.There may be presence of recombination hotspots of ethnic specificity and with variable recombination rates.

As a traditional method for the assessment of colon dynamics, radio-opaque markers (ROMs) are limited in clinical use because of their ionizing radiation. We compared the accuracy and applicability of gadolinium-based capsules with ROMs in the measurement of colon dynamics in healthy controls and slow transit constipation (STC) patients. Seven patients with STC and nine healthy controls under a normal diet orally consumed ROMs and gadolinium-based capsules simultaneously. All subjects underwent X-ray and magnetic resonance imaging (MRI). Healthy control images were acquired at 12, 24, and 48 h, and STC patient images were acquired at 24, 48, and 72 h. The scores based on the position of the labeling capsules and ROMs in the colon and the colon transit times (CTTs) in the two groups were compared. The CTTs obtained via the ROMs were 34.7±17.4 and 67.3±6.5 h in the healthy controls and STC patients, respectively (P<.05). The CTTs obtained via MRI were 30.9±15.9 and 74.1±7.2 h in the healthy controls and STC patients, respectively (P<.05). The CTTs of the STC patients were significantly longer than the healthy controls. The correlation (r s ) between the scores based on the position of the labeling capsule and ROMs in the healthy group and the STC patients was .880 (P<.05) and .889 (P<.05), respectively. As a MRI contrast label, gadolinium-based capsules exhibit results comparable to ROMs in colon motility measurements. © 2017 John Wiley & Sons Ltd.

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.

The aim of this study was to examine sleep disturbances in patients with chronic mountain sickness (CMS). The sleep of 14 patients with CMS and 11 healthy controls with or without sleep disorders (control N: without sleep disorders; control D: with sleep disorders) was studied by polysomnography. Hypopnea was the sleep disorder most commonly suffered by CMS patients and control D subjects. No major differences were observed in sleep structure between CMS and control groups, with the exception of shorter rapid eye movement latency in controls and increased deep non-rapid eye movement in the control N group. Periodic breathing was observed in only two study participants, one each in the CMS and control D groups. The level of saturated oxygen was significantly lower in the CMS group during sleep than the control groups (P<0.05). CMS scores were positively correlated with the apnea-hypopnea index, and negatively correlated with saturated oxygen levels. These results demonstrate that sleep disorders and nocturnal hypoxia are important in the development of CMS. Copyright © 2014 Elsevier B.V. All rights reserved.

The purpose of this study was to estimate the caloric intake and fat consumption in children with celiac disease (CD) following a gluten-free diet (GFD). This study enrolled 100 subjects, including 50 children with CD on a gluten-free diet and a control group of 50 healthy children. Statistical analysis to compare groups was performed using one-way ANOVA. A significant increase in fat consumption was observed in children with CD as compared to healthy children. The daily fat intake was 72.5 +/- 37.2 g per 100 g of food in the CD group and 52.9 +/- 35.4 g per 100 g of food in the control group (p < 0.008). A significant difference in fat intake was found between celiac and healthy females (10.21 +/- 3.15 g/100 g in the celiac group vs 7.46 +/- 2.91 g/100 g in the control group), p = 0.004. This study describes a significantly higher fat consumption in patients with CD on GFD as compared to controls. This increase was more pronounced in females and during the puberal age. Based on these interesting preliminary results we estimate that further investigations are necessary, such as a randomized multicentre study on the long-term effects of GFD with particular attention to the imbalance in daily fat intake.

The aim of this study is to explore and compare through polysomnography respiratory sleep parameters between children with idiopathic epilepsy and healthy children. Our cross-sectional study included 40 children with idiopathic epilepsy and 27 healthy children, who underwent overnight polysomnography. Data about sleep respiratory parameters were obtained and statistically analyzed. The level of statistical significance was set at 0.05. The prevalence of Obstructive Sleep Apnea Syndrome was significantly higher in the epilepsy group (35% vs 7.4%, p<0.01). Moreover, the odds ratio of an obstructive apnea index ≥1 in the epilepsy group was 10.6 (95% Confidence Intervals: 3.08-37.08) in comparison to the control group. The mean value of the obstructive apnea-hypopnea index was significantly higher in children with epilepsy compared to healthy children (2.46±1.22 vs 1.21±0.83, p=0.027). The mean values of central apnea index and desaturation index were comparable between these two groups. Longest apnea duration was significantly higher in the group of poor seizure control. All other sleep respiratory variables did not differ significantly between children with poor and good seizure control and between children with generalized and focal epilepsy. Children with epilepsy seem to present more prominent sleep breathing instability in comparison to healthy children, which mainly includes a predisposition to obstructive respiratory events. More studies are needed to investigate the relationship between sleep apneas and seizure control. Copyright © 2016 Elsevier B.V. All rights reserved.

Seventy-eight healthy young adults (33 male, mean age 24.0 ± 2.2 years; 18 APP and/or presenilin1/2 mutation carriers [APP/presenilin-1/2 group], 30 APOE ε4 subjects [APOE ε4 group], and 30 subjects without the above-mentioned genes [control group]) underwent resting-state functional MR imaging and neuropsychological assessments. Bilateral hippocampus functional connectivity patterns were compared among three groups. The brain regions with statistical differences were then extracted, and correlation analyses were performed between Z values of the brain regions and neuropsychological results. Compared with control group, both APOE ε4 group and APP/presenilin-1/2 group showed increased functional connectivity in medial prefrontal cortex and precuneus for the seeds of bilateral hippocampi. The APOE ε4 group displayed increased functional connectivity from bilateral hippocampi to the left middle temporal gyrus compared with the control group. Moreover, compared with the APP/presenilin-1/2 group, the APOE ε4 group also had markedly increased functional connectivity in right hippocampus-left middle temporal gyrus. The Z values of right hippocampus-left middle temporal gyrus correlated with various neuropsychological results across all the subjects, as well as in APOE ε4 group. Young healthy adults carrying APOE ε4 and APP/presenilin-1/2 displayed different hippocampus functional connectivity patterns, which may underlie the discrepant mechanisms of gene-modulated cognitive dysfunction in Alzheimer's disease.

Oligoclonal bands of IgG (OB) are proposed as an early prognostic factor of the disease. Growing attention is directed towards brain volume evaluation as a possible marker of the severity of MS. Previous studies found that MS patients lacking OB have less brain atrophy. to evaluate a possible relationship between OB and cerebral volume in a cohort of early MS patients. Inclusion criteria were: diagnosis of relapsing-remitting MS; CSF analysis and MRI acquired simultaneously and within 12 months from clinical onset. A total of 15 healthy controls underwent MRI. In 20 MS patients, CSF analysis did not show OB synthesis (OB negative group). A control group of 25 MS patients in whom OB was detected was also randomly recruited (OB positive group). T test showed a significant difference in NWV between the OB positive and OB negative groups (P value = 0.01), and between the OB positive group and the healthy controls (P value = 0.001). No differences were detected between OB negative group and healthy controls. Multivariable linear regression showed a relationship between NWV and OB synthesis (P value = 0.02) controlling for age, gender, and EDSS. Our preliminary results suggest that OB positive patients show more atrophy of white matter since early phases of the disease, supporting the role of CSF analysis as a prognostic factor in MS.

This study attempted to longitudinally investigate neuropsychological function, illness representations, self-esteem, mood and quality of life (QoL) in individuals with chronic fatigue syndrome (CFS) and compared them with both healthy participants and a clinical comparison group of individuals with autoimmune thyroid disease (AITD). Neuropsychological evaluation was administered at two time points, five weeks apart. Twenty-one individuals with CFS, 20 individuals with AITD and 21 healthy participants were matched for age, pre-morbid intelligence, education level and socio-economic status (SES). All groups also completed measures of illness perceptions, mood, self-esteem and QoL at both time points. The CFS group showed significantly greater impairment on measures of immediate and delayed memory, attention and visuo-constructional ability, and reported significantly higher levels of anxiety and depression. After controlling for the effects of mood, the CFS group still demonstrated significant impairment in attention. The CFS group also reported significantly lower self-reported QoL than the AITD and healthy participants. In terms of illness perceptions, the AITD group believed that their condition would last longer, that they had more treatment control over their condition, and reported less concern than the CFS group. These results suggest that the primary cognitive impairment in CFS is attention and that this is not secondary to affective status. The lower treatment control perceptions and greater illness concerns that CFS patients report may be causally related to their affective status.

Neuromuscular and mechanical deficiencies are commonly studied in participants with chronic ankle instability (CAI). Few investigators have attempted to comprehensively consider sensorimotor and mechanical differences among people with CAI, copers who did not present with prolonged dysfunctions after an initial ankle sprain, and a healthy control group. To determine if differences exist in spinal reflex excitability and ankle laxity among participants with CAI, copers, and healthy controls. Case-control study. Research laboratory. Thirty-seven participants with CAI, 30 participants categorized as copers, and 26 healthy control participants. We assessed spinal reflex excitability of the soleus using the Hoffmann reflex protocol. Participants' ankle laxity was measured with an instrumented ankle arthrometer. The maximum Hoffmann reflex : maximal muscle response ratio was calculated. Ankle laxity was measured as the total displacement in the anterior-posterior directions (mm) and total rotation in the inversion and eversion directions (°). Spinal reflex excitability was diminished in participants with CAI compared with copers and control participants (P = .01). No differences were observed among any of the groups for ankle laxity. Changes in the spinal reflex excitability of the soleus that likely affect ankle stability were seen only in the CAI group, yet no mechanical differences were noted across the groups. These findings support the importance of finding effective ways to increase spinal reflex excitability for the purpose of treating neural excitability dysfunction in patients with CAI.

Prior work has repeatedly demonstrated that people who have current major depression exhibit blunted cardiovascular reactivity to acute stressors (e.g., Salomon et al., 2009). A key question regards the psychobiological basis for these deficits, including whether such deficits are depressed mood-state dependent or whether these effects are trait-like and are observed outside of depression episodes in vulnerable individuals. To examine this issue, we assessed cardiovascular reactivity to a speech stressor task and a forehead cold pressor in 50 individuals with current major depressive disorder (MDD), 25 with remitted major depression (RMD), and 45 healthy controls. Heart rate (HR), blood pressure and impedance cardiography were assessed and analyses controlled for BMI and sex. Significant group effects were found for SBP, HR, and PEP for the speech preparation period and HR, CO, and PEP during the speech. For each of these parameters, only the MDD group exhibited attenuated reactivity as well as impaired SBP recovery. Reactivity and recovery in the RMD group more closely resembled the healthy controls. Speeches given by the MDD group were rated as less persuasive than the RMD or healthy controls' speeches. No significant differences were found for the cold pressor. Blunted cardiovascular reactivity and impaired recovery in current major depression may be mood-state dependent phenomena and may be more reflective of motivational deficits than deficits in the physiological integrity of the cardiovascular system.

Childhood Trauma and Minimization/Denial in People with and without a Severe Mental Disorder.

PubMed

Church, Chelsea; Andreassen, Ole A; Lorentzen, Steinar; Melle, Ingrid; Aas, Monica

Background: Childhood trauma has garnered extensive research concerning its role in the psychopathology of mental disorders, including psychosis. The Childhood Trauma Questionnaire (CTQ) utilizes a minimization/denial (MD) scale to denote potential under-reporters of trauma, yet MD scores are infrequently reported and validations of the scale are lacking in the literature. Elucidate differences in MD between patients with severe mental disorders to healthy individuals, and secondly, investigate if MD influences reports of childhood trauma between the groups. Methods: We included 621 patients with a DSM-schizophrenia spectrum, bipolar spectrum diagnosis, or major depression disorder with psychotic features and 299 healthy controls as part of the NORMENT study in Oslo, Norway. History of childhood trauma was obtained using the CTQ. Clinical diagnoses were assessed using the Structured Clinical Interview for DSM Disorders. Results: A significantly greater proportion of healthy controls (42.8%) had a positive MD score compared to patients (26.7%). When controlling for MD, the patient group still exhibited elevated reports of childhood trauma compared to controls (Cohen's d = 1.27), concordant with reports of childhood trauma being more frequently reported in a population of severe mental disorders. Conclusion: Elevated MD in the healthy control group could suggest an enhanced self-serving bias, potentially attenuated in the psychiatric group. Clinicians and researchers would benefit from including the MD component of CTQ when assessing retrospective information on childhood trauma to rule out potential effect of MD.

The development of technological applications that allow people to control and embody external devices within social interaction settings represents a major goal for current and future brain-computer interface (BCI) systems. Prior research has suggested that embodied systems may ameliorate BCI end-user's experience and accuracy in controlling external devices. Along these lines, we developed an immersive P300-based BCI application with a head-mounted display for virtual-local and robotic-remote social interactions and explored in a group of healthy participants the role of proprioceptive feedback in the control of a virtual surrogate (Study 1). Moreover, we compared the performance of a small group of people with spinal cord injury (SCI) to a control group of healthy subjects during virtual and robotic social interactions (Study 2), where both groups received a proprioceptive stimulation. Our attempt to combine immersive environments, BCI technologies and neuroscience of body ownership suggests that providing realistic multisensory feedback still represents a challenge. Results have shown that healthy and people living with SCI used the BCI within the immersive scenarios with good levels of performance (as indexed by task accuracy, optimizations calls and Information Transfer Rate) and perceived control of the surrogates. Proprioceptive feedback did not contribute to alter performance measures and body ownership sensations. Further studies are necessary to test whether sensorimotor experience represents an opportunity to improve the use of future embodied BCI applications.

To compare the intensity and the profile of psychotic symptoms and the characteristics of parental bonding of male schizophrenia patients with a history of homicide and those without a history of violent behaviour. Clinical question - We hypothesized more intense psychotic symptoms, especially positive symptoms as signs of a more severe psychopathology in the background of homicidal behaviour. We also hypothesized a more negatively perceived pattern (less Care more Overprotection) of parental bonding in the case of homicidal schizophrenia patients than in non-violent patients and non-violent healthy controls. Symptom severity and symptom profiles were assessed with the Positive and Negative Syndrome Scale in a group of male schizophrenia patients (n=22) with the history of committed or attempted homicide, and another group (n=19) of male schizophrenia patients without a history of violent behaviour. Care- and Overprotection were assessed using the Parental Bonding Instrument (PBI) in a third group of non-violent healthy controls (n=20), too. Positive, negative and general psychopathology symptoms in the homicidal schizophrenia group were significantly (p<0.005) more severe than in the non-violent schizophrenia group. Non-violent schizophrenia patients scored lower on Care and higher on Overprotection than violent patients and healthy controls. Homicidal schizophrenia patients showed a pattern similar to the one in the healthy control group. It seems imperative to register intense positive psychotic symptoms as predictive markers for later violent behaviour. In the subgroup of male homicidal schizophrenia patients negatively experienced parental bonding does not appear to be major contributing factor to later homicidal behaviour.

Study Design Controlled laboratory study. Background Recurrent ankle sprains associated with chronic ankle instability (CAI) occur not only in challenging sports but also in daily walking. Understanding whether and how CAI alters feedback and feedforward controls during walking may be important for developing interventions for CAI prevention or treatment. Objective To understand whether CAI is associated with changes in feedback and feedforward control when individuals with CAI are subjected to experimental perturbation during walking. Methods Twelve subjects with CAI and 12 control subjects walked on a treadmill while adapting to external loading that generated inversion perturbation at the ankle joint. Ankle kinematics around heel contact during and after the adaptation were compared between the 2 groups. Results Both healthy and CAI groups showed an increase in eversion around heel contact in early adaptation to the external loading. However, the CAI group adapted back toward the baseline, while the healthy controls showed further increase in eversion in late adaptation. When the external loading was removed in the postadaptation period, healthy controls showed an aftereffect consisting of an increase in eversion around heel contact, but the CAI group showed no aftereffect. Conclusion The results provide preliminary evidence that CAI may alter individuals' feedback and feedforward control during walking. J Orthop Sports Phys Ther 2016;46(9):775-783.

To compare physical fitness between rice farmers with chronic low back pain (CLBP) and a healthy control group. Sixty-eight rice farmers with CLBP were matched according to age and sex with healthy farmers. All subjects underwent nine physical fitness tests for body composition, lifting capacity, static back extensor endurance, leg strength, static abdominal endurance, handgrip strength, hamstring flexibility, posterior leg and back muscles flexibility and abdominal flexibility. There was no significant difference between CLBP and healthy groups for all tests, except the static back extensor endurance. The back extensor endurance times of the CLBP group was significantly lower than that of the control group (p = 0.002). Static back extensor endurance is the deficient physical fitness in CLBP rice farmers. Back extensor endurance training should be emphasized in both prevention and rehabilitation programs.

Suicide is a major social and clinical problem in Asia. Although studies have suggested that personality traits are possible risk factors for suicide, no study has been conducted among Chinese to compare the temperament traits of suicidal and non-suicidal mood disorder patients with those of healthy controls. This study compared temperament traits of two patient groups, those with a mood disorder who have attempted suicide (n=204), and those with a mood disorder who have not attempted suicide (n=160), and compared the traits of these patients to those of healthy controls (n=178), assessed by Cloninger's Tridimensional Personality Questionnaire and the Brown-Goodwin Aggression Inventory. Patients with suicidal attempts had significantly higher novelty seeking and aggression scores than healthy controls and patients without suicidal attempts. Two groups of patients with mood disorder had significantly higher harm avoidance scores than the healthy controls. However, patients with suicidal attempts did not have higher harm avoidance scores than patients without suicidal attempts. This study confirms findings that harm avoidance and mood disorder are related, and extends them by suggesting that those with a mood disorder and suicide attempts have higher novelty seeking and lifetime aggression scores than those without suicidal attempt, either patients or healthy controls.

Background The impact of personalized exercise training and a healthy dietary lifestyle in healthy volunteers on coronary flow reserve and cardiovascular function remains to be investigated in a controlled study setting. Purpose To examine the effects of a Mediterranean-inspired diet combined with regular physical exercise (standard) and a personalized supervised exercise program (DAPS) on coronary flow reserve and cardiovascular function. Results The number of males were 10 (59%) and 9 (47%) and mean age was 54 ± 12 and 55 ± 5 years in standard versus DAPS group, respectively. Primary outcomes were in addition to improved body composition and aerobic capacity, increased TDE-CFR (5.0%, CI:1.62,8.64, p = 0.005) and left ventricle ejection fraction (LVEF) during hyperemia (10.2%, CI:1.62,19.4, p = 0.022) in DAPS adjusted for the control period. Also, plasma fibrinogen decreased (−12.1%, CI:-22.0,–0.92, p = 0.035) in the DAPS group. Secondary outcomes, after adjusting DAPS intervention effects for the standard-training period, TDE-CFR and hyperemic LVEF remained significantly improved. Materials and Methods This randomized, controlled clinical trial (URL: http://www.clinicaltrials.gov NCT02713724) included 36 healthy volunteers who underwent exercise ECG before randomization to standard or DAPS groups. Standard-group was given gym-membership with limited instructions and general dietary advice. DAPS-group received personalized supervised exercise programs and more detailed dietary advice with regular contact with a personal trainer. Effects were evaluated after 3 months. All participants underwent coronary flow reserve by transthoracic ultrasound (TDE-CFR), blood marker analysis and examinations of vascular function. Standard-group was evaluated pre-control, post-control (=pre-intervention) and post-intervention. DAPS-group was examined at pre-intervention and post-intervention. Conclusions A personalized supervised training- and diet program improves cardiovascular status in healthy subjects with a physically inactive lifestyle and may be a promising approach for cardiovascular prevention in the general population.

To make a study of the cytokine changes in community-acquired pneumonia (CAP) in the elderly and the intervention of traditional Chinese medicine that can clear away the lung-heat and dissipate blood stasis (Qingfeihuayu soup). The 82 cases with CAP in the elderly were divided at random into two treatment group and control group. Based on heteropathy, the treatment group was given Qingfeihuayu soup two times a day. The control group was given Rocephin 2 g once daily for 7 days. The clinical effect and the changes in TNF-alpha, IL-6 and IL-10 were observed before and after the treatment. A healthy group was also set up. Before treatment, IL-6 and TNF-alpha in both groups were higher than the healthy group (P < 0.01) and IL-10 lower than the healthy group (P < 0.01). After treatment, IL-6 and TNF-alpha in both groups decreased (P < 0.01) while IL-10 in treatment group increased. There existed a great difference compared with the control group (P < 0.01). The total effective rate in the treatment group is 92.50% while the control group is 85.71%. thus have a great difference (P < 0.05). During the process of the development of CAP in the elderly, there existed the phenomenon of the excessive release of TNF-alpha, IL-6 and the too much inhibition of IL-10. The unbalance of TNF-alpha, IL-6, IL-10 can be a monitoring index reflecting the severity of the disease. The Chinese medicine Qingfeihuayu soup has obviously have regulating and clinical effect.

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

Dental implant insertion for oral rehabilitation is a worldwide procedure for healthy and medically compromised patients. The impact of systemic disease risks on the outcome of implant therapy is unclear, since there are few if any published randomized controlled trials (RCTs). The objective of this study is to investigate the rate of complications and failures following dental implantation in medically compromised patients in order to elucidate risk factors and prevent them. A retrospective cohort study was conducted from patient files treated with dental implantation between the years 2008-2014. The study group consisted of medically complex patients while the control group consisted of healthy patients. Preoperative, intraoperative, and post operative clinical details were retrieved from patients' files. The survival rate and the success rate of the dental implants were evaluated clinically and radiographically. A total of 204 patients (1003 dental implants) were included in the research, in the study group, 93 patients with 528 dental implants and in the control group, 111 patients with 475 dental implants. No significant differences were found between the groups regarding implant failures or complications. The failure rate of dental implants among the patients was 11.8 % in the study group and 16.2 % in the control group (P = 0.04). It was found that patients with a higher number of implants (mean 6.8) had failures compared with patients with a lower number of implants (mean 4.2) regardless of their health status (P < 0.01). We found a similar rate of failure and complications of dental implantation in medically complex patients and in healthy patients. Medically complex patients can undergo dental implantation. There are similar rates of complications and failures of dental implants in medically complex patients and in healthy patients.

To assess if the acute hypoglycemic effect of nopal which occurs in diabetic patients also appears in healthy individuals, 500 g of nopal stems (O. streptacantha Lem.) were given orally to 14 healthy volunteers and to 14 patients with NIDDM. Serum glucose and insulin levels were measured at 0, 60, 120 and 180 minutes after nopal ingestion. A control test was performed with the intake of 400 ml of water. The intake of nopal by the NIDDM group was followed by a significant reduction of serum glucose and insulin concentration reaching 40.8 + 4.6 mg/dl (n = 14) (mean+SEM) and 7.8 + 1.5 uU/ml (n = 7) less than basal value, respectively, at 180 minutes. (P less than 0.001 vs control test). No significant changes were noticed in the healthy group as compared with the control test (P greater than 0.05). Acute hypoglycemic effect of nopal was observed in patients with NIDDM but not in healthy subjects, thus the mechanisms of this effect differs from current hypoglycemic agents.

Although obesity and mental health disorders are two major public health problems in adolescents that affect academic performance, few rigorously designed experimental studies have been conducted in high schools. The goal of the study was to test the efficacy of the COPE (Creating Opportunities for Personal Empowerment) Healthy Lifestyles TEEN (Thinking, Emotions, Exercise, Nutrition) Program, versus an attention control program (Healthy Teens) on: healthy lifestyle behaviors, BMI, mental health, social skills, and academic performance of high school adolescents immediately after and at 6 months post-intervention. A cluster RCT was conducted. Data were collected from January 2010 to May of 2012 and analyzed in 2012-2013. A total of 779 culturally diverse adolescents in the U.S. Southwest participated in the trial. COPE was a cognitive-behavioral skills-building intervention with 20 minutes of physical activity integrated into a health course, taught by teachers once a week for 15 weeks. The attention control program was a 15-session, 15-week program that covered common health topics. Primary outcomes assessed immediately after and 6 months post-intervention were healthy lifestyle behaviors and BMI. Secondary outcomes included mental health, alcohol and drug use, social skills, and academic performance. Post-intervention, COPE teens had a greater number of steps per day (p=0.03) and a lower BMI (p=0.01) than did those in Healthy Teens, and higher average scores on all Social Skills Rating System subscales (p-values <0.05). Teens in the COPE group with extremely elevated depression scores at pre-intervention had significantly lower depression scores than the Healthy Teens group (p=0.02). Alcohol use was 12.96% in the COPE group and 19.94% in the Healthy Teens group (p=0.04). COPE teens had higher health course grades than did control teens. At 6 months post-intervention, COPE teens had a lower mean BMI than teens in Healthy Teens (COPE=24.72, Healthy Teens=25.05, adjusted M=-0.34, 95% CI=-0.56, -0.11). The proportion of those overweight was significantly different from pre-intervention to 6-month follow-up (chi-square=4.69, p=0.03), with COPE decreasing the proportion of overweight teens, versus an increase in overweight in control adolescents. There also was a trend for COPE Teens to report less alcohol use at 6 months (p=0.06). COPE can improve short- and more long-term outcomes in high school teens.

To compare plasma levels of F-actin, G-actin and thymosin beta 4 (TB4) in humans with septic shock, noninfectious systemic inflammatory response syndrome (SIRS) and healthy controls. F-actin was significantly elevated in septic shock as compared with noninfectious SIRS and healthy controls. G-actin levels were greatest in the noninfectious SIRS group but significantly elevated in septic shock as compared with healthy controls. TB4 was not detectable in the septic shock or noninfectious SIRS group above the assay's lowest detection range (78 ng/ml). F-actin is significantly elevated in patients with septic shock as compared with noninfectious SIRS. F-actin and the F:G-actin ratio are potential biomarkers for the diagnosis of septic shock.

To assess the value of immunoregulants in improving the prognosis of infants with wheezing. Forty-three infants with wheezing with given oxygen support, injection or inhalation of glucocorticosteroids or bronchodilatator to relieve the symptoms. Of these infants, 24 received immunoregulant treatment with bronchovaxom at the daily dose of 3.5 mg for 10 days every a month for a treatment course of 3 months. The other 19 infants were managed with budesonide aerosol at 200 microg once or twice daily for 3 months (basic treatment group). All the infants were followed up for 1 year to record the number of wheezing episode and infections. Ten healthy infants were also included in this study as the control group. In infants with bronchovaxom treatment, 25% reported more than 3 wheezing episodes within the 1-year follow-up, a rate significantly lower than that in the control group (63.2%, Chi(2)=6.344, P<0.05). The episodes of respiratory infection were similar between bronchovaxom group and the healthy control group (t=0.72, P>0.05), but significantly higher in the basic treatment group than in bronchovaxom and the healthy control group (t=3.11 and 3.92, respectively. P<0.05). Bronchovaxom can effectively reduce the recurrence of wheezing and respiratory infections in the infants with wheezing attack to reduce the risks of asthma development.

Pilot testing of the "First You Should Get Stronger" program among caregivers of older adults with dementia.

Lök, Neslihan; Bademli, Kerime

In this study, randomized controlled interventional study pattern was used to examine the effects of the "First You Should Get Stronger" program on the caregiving burden and healthy life style behavior of caregivers of dementia patients. "Zarit Caregiver Burden Scale" and "Healthy Life Style Behavior Scale" were used. The study was completed with 40 caregivers in total with 20 in the intervention group and 20 in the control group. A statistically significant difference was determined between the "Zarit Caregiving Burden Scale" and "Healthy Life Style Behavior Scale" score averages of the intervention group that participated in the "First You Should Get Stronger" program in comparison with those of the control group. It is important for the healths of caregivers to include similar programs for the caregivers of dementia patients in continuous and regular applications. The results highlight the importance of the "First You Should Get Stronger" program significantly decreased the caregiving burden and significantly developed the healthy lifestyle behaviors of caregivers in the intervention group. Since dementia is a difficult neurological syndrome with patients cared at home, it generally wears out the caregivers significantly. It is suggested that the nurses and healthcare professionals working with dementia patients are evaluated separately and that they carry out caregiving applications within the scope of the "First You Should Get Stronger" program.

To improve a sustainable healthy working life, we have developed the intervention 'Staying healthy at work', which endeavours to enhance work participation of employees aged 45 years and older by increasing their problem-solving capacity and stimulating their awareness of their role and responsibility towards a healthy working life. This research study aims to evaluate the process and the effectiveness of the intervention compared with care as usual. The study is a cluster-randomized controlled trial design (randomized at the supervisor level), with a 1-year follow-up. Workers aged 45 years and older have been enrolled in the study. Workers in the intervention group are receiving the intervention 'Staying healthy at work'. The main focus of the intervention is to promote a healthy working life of ageing workers by: (1) changing workers awareness and behaviour, by emphasizing their own decisive role in attaining goals; (2) improving the supervisors' ability to support workers in taking the necessary action, by means of enhancing knowledge and competence; and (3) enhancing the use of the human resource professionals and the occupational health tools available within the organization. The supervisors in the intervention group have been trained how to present themselves as a source of support for the worker. Workers in the control group are receiving care as usual; supervisors in the control group have not participated in the training. Measurements have been taken at baseline and will be followed up at 3, 6 and 12 months. The primary outcome measures are vitality, work ability and productivity. The secondary outcomes measures include fatigue, job strain, work attitude, self-efficacy and work engagement. A process evaluation will be conducted at both the supervisor and the worker levels, and satisfaction with the content of the intervention will be assessed. The intervention 'Staying healthy at work' has the potential to provide evidence-based knowledge of an innovative method to promote a sustainable healthy working life in the older working population. The results of the study will be relevant for workers, employers, occupational health professionals and human resource professionals. The trial is registered with the Dutch Trial Register under number NTR2270.

Allergic diseases are triggered by Th2-mediated immune reactions to allergens and orchestrated by various immunological factors, including immune cells and cytokines. Although many reports have suggested that childhood is the critical period in the onset of allergic diseases and aging leads to alter the susceptibility of an individual to allergic diseases, age-related changes in various immunological factors in healthy individuals as well as their difference between healthy and allergic children have not yet been established. We investigated the ratio of Th1/Th2 cells and the levels of 22 allergy-related cytokines across all age groups in individuals who were classified as clinically non-atopic and healthy. We also examined their differences between healthy and allergic children to evaluate immunological changes induced by the development of allergic diseases during childhood. The Th1/Th2 ratio rose gradually during the growth period including childhood, reaching peak values in the twenties-thirties age group. Th1/Th2 ratios were significantly lower in allergic children than in healthy controls, whereas 14 of 22 cytokines were significantly higher in allergic children than in healthy controls. On the other hand, there were no differences in Th1/Th2 ratios and cytokines between healthy and allergic adolescents. In this study, age-related changes in Th1/Th2 ratios were found in normal controls across all age groups, and decreases in Th1/Th2 ratio were observed with increasing of 14 cytokines in allergic children. The results of this study may be helpful as reference values for both monitoring immunological changes according to aging in healthy individuals and distinguishing between normal and allergic subjects in terms of immune cells and soluble factors.

2017-07-01

Individuals with chronic ankle instability (CAI) have demonstrated strength deficits compared to healthy controls; however, the influence of ankle position on force measures and surface electromyography (sEMG) activation of the peroneus longus and brevis has not been investigated. The purpose of this study was to compare sEMG amplitudes of the peroneus longus and brevis and eversion force measures in 2 testing positions, neutral and plantarflexion, in groups with and without CAI. Twenty-eight adults (19 females, 9 males) with CAI and 28 healthy controls (19 females, 9 males) participated. Hand-held dynamometer force measures were assessed during isometric eversion contractions in 2 testing positions (neutral, plantarflexion) while surface sEMG amplitudes of the peroneal muscles were recorded. Force measures were normalized to body mass, and sEMG amplitudes were normalized to a resting period. The group with CAI demonstrated less force when compared to the control group ( P < .001) in both the neutral and plantarflexion positions: neutral position, CAI: 1.64 Nm/kg and control: 2.10 Nm/kg) and plantarflexion position, CAI: 1.40 Nm/kg and control: 1.73 Nm/kg). There were no differences in sEMG amplitudes between the groups or muscles ( P > .05). Force measures correlated with both muscles' sEMG amplitudes in the healthy group (neutral peroneus longus: r = 0.42, P = .03; plantarflexion peroneus longus: r = 0.56, P = .002; neutral peroneus brevis: r = 0.38, P = .05; plantarflexion peroneus longus: r = 0.40, P = .04), but not in the group with CAI ( P > .05). The group with CAI generated less force when compared to the control group during both testing positions. There was no selective activation of the peroneal muscles with testing in both positions, and force output and sEMG activity was only related in the healthy group. Clinicians should assess eversion strength and implement strength training exercises in different sagittal plane positions and evaluate for other pathologies that may contribute to reduced eversion strength in patients with CAI.

The main objective of this study was to investigate the gray matter volume (GMV) differences between the patients with social anxiety disorder (SAD) and healthy controls, using VBM analysis. A total of 27 consecutive patients (15 women and 12 men) with SAD and 27 age and sex-matched healthy control subjects were included in this study. With magnetic resonance imaging, we examined GMV differences between SAD and healthy control groups. We found that GMV in the right middle and inferior temporal, left superior parietal, left precuneus and right fusiform areas were significantly greater in patients with SAD than in healthy controls. In addition, GMV in the right inferior and middle temporal regions were positively correlated with the social avoidance and total social anxiety scores of the participants in the SAD group. Lastly, greater GMV in the left superior parietal and precuneal regions were correlated with the higher disability in the social life of the patients with SAD. Our results suggest that the regions that showed significant GMV differences between the two groups play an important role in the pathophysiology of SAD and increased GMV in these regions might reflect a pathological process of neural abnormalities in this disorder.

This prospective study was designed to compare the hair levels of 36 elements in 52 patients with stage III breast cancer to those of an equal number of healthy individuals. Principal component and cluster analysis were used for source of identification and apportionment of heavy metals and trace elements in these two groups. A higher average level of iron was found in samples from patients while controls had higher levels of calcium. Both patients and controls had elevated levels of tin, magnesium, zinc, and sodium. Almost all element values in cancer patients showed higher dispersion and asymmetry than in healthy controls. Between the two groups, there were statistically significant differences in the concentrations of silver, arsenic, gold, boron, barium, beryllium, calcium, cadmium, cerium, cobalt, cesium, gadolinium, manganese, nickel, lead, antimony, scandium, selenium, and zinc (p < 0.05). Strong positive correlations were found between lead and gold (r = 0.785) in the cancer group and between palladium and cobalt (r = 0.945) in the healthy individuals. Our results show that there are distinct patterns of heavy metals and trace elements in the hair of breast cancer patients in comparison to healthy controls. These results could be of significance in the diagnosis of breast cancer.

To evaluate the serum levels of zinc and copper in epileptic children during the long-term treatment of anticonvulsant drugs and correlate this with healthy subjects. A hospital-based group matched case-control study was conducted in the Department of Pediatrics, Faculty of Medicine, Zagazig University, Zagazig, Egypt between November 2013 and October 2014. Ninety patients aged 7.1 ± 3.6 years were diagnosed with epilepsy by a neurologist. The control group was selected from healthy individuals and matched to the case group. Serum zinc and copper were measured by the calorimetric method using a colorimetric method kit. The mean zinc level was 60.1 ± 22.6 ug/dl in the cases, and 102.1 ± 18 ug/dl in the controls (p<0.001). The mean copper level was 180.1 ± 32.4 ug/dl in cases compared with 114.5 ± 18.5 ug/dl in controls (p<0.001). Serum zinc levels in epileptic children under drug treatment are lower compared with healthy children. Also, serum copper levels in these patients are significantly higher than in healthy people. No significant difference in the levels of serum copper and zinc was observed in using one drug or multiple drugs in the treatment of epileptic patients.

Anhedonia has traditionally been considered a characteristic feature of schizophrenia, but the true nature of this deficit remains elusive. This study sought to investigate consummatory and anticipatory pleasure as it relates to motivation deficits. Eighty-four outpatients with schizophrenia and 81 healthy controls were administered the Temporal Experience of Pleasure Scale (TEPS), as well as a battery of clinical and cognitive assessments. Multivariate analyses of variance were used to examine the experience of pleasure as a function of diagnosis, and across levels of motivation deficits (i.e. low vs. moderate. vs. high) in schizophrenia. Hierarchical regression analyses were also conducted to evaluate the predictive value of amotivation in relation to the TEPS. There were no significant differences between schizophrenia and healthy control groups for either consummatory or anticipatory pleasure. Within the schizophrenia patients, only those with high levels of amotivation were significantly impaired in consummatory and anticipatory pleasure compared to low and moderate groups, and compared to healthy controls. Further, our results revealed that amotivation significantly predicts both consummatory and anticipatory pleasure, with no independent contribution of group. Utilizing study samples with a wide range of motivation deficits and incorporating objective paradigms may provide a more comprehensive understanding of hedonic deficits.

The purpose of this study was to determine the effect of the isolated vocal-facilitating techniques Chant Talk and Pitch Inflections on the phonation of healthy female speech-language pathology (SLP) students. A multigroup pretest-posttest design was used. A homogenous group of 40 healthy female SLP students with a mean age of 18.7 years were randomly assigned into 3 groups: a Chant Talk group (practicing Chant Talk across 18 weeks), a Pitch Inflections group (practicing Pitch Inflections across 18 weeks), and a control group (practicing no facilitating techniques). To compare vocal measures before and after this time span, an identical objective voice assessment protocol (aerodynamic measurement, acoustic analysis, voice range profile, and Dysphonia Severity Index) was performed in the 3 groups. Both Chant Talk and Pitch Inflections groups resulted in a significant decrease of the acoustic measure noise-to-harmonics ratio compared with the control group. The Chant Talk group resulted in a significant increase in the acoustic measure fundamental frequency compared with the control group. The results of this pilot study suggest that the facilitating techniques Chant Talk and Pitch Inflections may improve the objective measure of breathiness (noise-to-harmonics ratio) in healthy female SLP students.

Today it is well known about mechanisms of cell communication, how the cells that mediate immune response and tissue injury accumulate in tissues but the aetiology of rheumatoid arthritis (RA) is still unknown. This study was to evaluate immunomodulatory effects of crude Entamoeba histolytica (HM1 IMS strain) antigen in complete freund's adjuvant female wistar rats by studying the alterations in humoral and cell mediated immune responses and also the inflammatory effects by evaluating the changes in body weight, paw thickness, biochemical, serological, interleukin-6 (IL-6), IL-10 and tumor necrosis factor-α (TNF-α) and histopathology activities. Animals were randomly divided into six groups (n=6). CFA was induced in arthritic, drug and AA+CFA group whereas, 0.5ml amoebic antigen was induced subplantal in AA group while 0.5ml dose of amoebic antigen was given orally to AA+CFA group for 7-28th days. Indomethacin was used as a standard drug. Effects of amoebic antigen were associated with increased paw thickness and decreased body weight when compared to healthy control showed a significant difference. Oral administration of amoebic antigen has showed increased severe symptoms of arthritis in AA+CFA on comparison to healthy control rats. Significant increase in serum level of IL-6 and α TNF were found in AA group followed by AA+CFA group whereas, decrease in concentration of IL-10 was appear in AA+CFA group on comparison to arthritic and healthy control group (P<0.05). Histopathology of AA group showed severe signs of necrotic and degenerative changes on comparison to healthy control group. Thus the results demonstrated that E. histolytica alone or in combination with CFA increased bone damage, with alterations in antioxidant level in liver and kidney tissue homogenates as well as showed immunomodulatory arthritogenic properties which may contribute and raise joint inflammation.

A cross-sectional and prospective longitudinal study on the anthropometric parameters and growth pattern of girls with adolescent idiopathic scoliosis (AIS). To investigate the growth pattern of girls with AIS with different severities, using cross-sectional and prospective longitudinal data set in comparison with age-matched healthy controls. AIS occurs in children during their pubertal growth spurt. Although there is no clear consensus on the difference in body height between girls with AIS and healthy controls, it is generally thought that the development and curve progression in girls with AIS is closely associated with their growth rate. There is no concrete prospective longitudinal study to document clearly the growth pattern and growth rate of subjects with AIS . A total of 611 girls with AIS and 296 healthy age-matched controls were included in the study and among them, 194 girls with AIS and 116 healthy controls were followed up until skeletal maturity. The girls with AIS were grouped into moderate (AIS20) and severe curve (AIS40) groups on the basis of maximum curve magnitude at skeletal maturity. Clinical data and detailed anthropometric parameters were recorded. In the cross-sectional analysis, the groups of subjects were compared within different age groups (from the age of 12-16 yr). In the longitudinal study, linear mixed modeling with respect to age or years since menarche was employed to formulate the growth trajectory of different anthropometric parameters. In the cross-sectional analysis, the girls with AIS were generally taller, with longer arm span and lower body mass index than the healthy controls. The girls with AIS40 were found to be significantly shorter in height (P = 0.006) and arm span (P = 0.025) at the age of 12 years but caught up and overtook the control group at the age of 14 to 16 years. In the longitudinal study, the average growth rate of arm span in girls with AIS40 was significantly higher than that in girls with AIS20 (> 30%) (P = 0.004) and controls (> 70%) (P = 0.0004). The age of menarche of girls with AIS40 was significantly delayed by 5.9 months and 3.8 months when compared with the control group and girls with AIS20, respectively (P < 0.05). The growth patterns of girls with AIS with confirmed curve severities were significantly different from healthy age-matched controls. Girls with severe AIS had delayed menarche with faster skeletal growth rate during the age of 12 to 16 years. Monitoring the rate of change of arm span of girls with AIS could be an important additional clinical parameter in helping predict curve severity in girls with AIS.

To assess cognitive performance and psychosocial functioning in patients with bipolar disorder (BD), in unaffected siblings, and in healthy controls. Subjects were patients with BD (n=36), unaffected siblings (n=35), and healthy controls (n=44). Psychosocial functioning was accessed using the Functioning Assessment Short Test (FAST). A sub-group of patients with BD (n=21), unaffected siblings (n=14), and healthy controls (n=22) also underwent a battery of neuropsychological tests: California Verbal Learning Test (CVLT), Stroop Color and Word Test, and Wisconsin Card Sorting Test (WCST). Clinical and sociodemographic characteristics were analyzed using one-way analysis of variance or the chi-square test; multivariate analysis of covariance was used to examine differences in neuropsychological variables. Patients with BD showed higher FAST total scores (23.90±11.35) than healthy controls (5.86±5.47; p < 0.001) and siblings (12.60±11.83; p 0.001). Siblings and healthy controls also showed statistically significant differences in FAST total scores (p = 0.008). Patients performed worse than healthy controls on all CVLT sub-tests (p < 0.030) and in the number of correctly completed categories on WCST (p = 0.030). Siblings did not differ from healthy controls in cognitive tests. Unaffected siblings of patients with BD may show poorer functional performance compared to healthy controls. FAST scores may contribute to the development of markers of vulnerability and endophenotypic traits in at-risk populations.

Limited biological research data are available on acute and transient psychotic disorder (ATPD) vis-à-vis schizophrenia. P300 event related potentials (ERP) have been extensively studied as an important neurophysiological parameter in schizophrenia. However, no P300 ERP studies comparing the two disorders are available. We compared auditory P300 ERP in patients remitted from ATPD with schizophrenia in remission and biologically unrelated healthy controls. In this case-control study design, 25 subjects remitted from ATPD were age-/gender-matched with healthy controls and patients with schizophrenia in remission. Clinical assessment and auditory P300 ERP (amplitude and latencies at central and parietal sites, reaction time) were recorded. The ERP parameters were compared across the three groups. All three groups showed significant differences in P300 amplitudes and latencies at central and parietal sites. Schizophrenia group differed significantly (p<0.001) from the ATPD group in all the P300 parameters. The ATPD group was found to have lower Pz latency (p<0.05) and lower mean reaction time (p<0.001) as compared to healthy controls. The results suggest that P300 could easily distinguish between ATPD and schizophrenia in remission, thus neurophysiologically differentiating the two disorders. Lower P300 latency and reaction time, which indicate hyper-arousability, distinguished ATPD from normal controls, with implications for a better understanding of ATPD. Copyright © 2016 Elsevier B.V.

Objective There is little understanding of the neural system abnormalities subserving adolescent major depressive disorder (MDD). In a cross-sectional study we compare currently unipolar depressed with healthy adolescents to determine if group differences in grey matter volume (GMV) were influenced by age and illness severity. Method Structural neuroimaging was performed on 109 adolescents with current MDD and 36 healthy controls, matched for age, gender, and handedness. GMV differences were examined within the anterior cingulate cortex (ACC) and across the whole-brain. The effects of age and self-reported depressive symptoms were also examined in regions showing significant main or interaction effects. Results Whole-brain voxel based morphometry revealed no significant group differences. At the whole-brain level, both groups showed a main effect of age on GMV, although this effect was more pronounced in controls. Significant group-by-age interactions were noted: A significant regional group-by-age interaction was observed in the ACC. GMV in the ACC showed patterns of age-related differences that were dissimilar between adolescents with MDD and healthy controls. GMV in the thalamus showed an opposite pattern of age-related differences in adolescent patients compared to healthy controls. In patients, GMV in the thalamus, but not the ACC, was inversely related with self-reported depressive symptoms. Conclusions The depressed adolescent brain shows dissimilar age-related and symptom-sensitive patterns of GMV differences compared with controls. The thalamus and ACC may comprise neural markers for detecting these effects in youth. Further investigations therefore need to take both age and level of current symptoms into account when disaggregating antecedent neural vulnerabilities for MDD from the effects of MDD on the developing brain.

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

The maintenance of balance is an essential requirement for the performance of daily tasks and sporting activities and muscular fatigue is a factor to impair postural control, so this study was done to compare the effect of selected muscle groups fatigue on postural control during bipedal stance in healthy subjects. Fifteen healthy female students (24.3 ± 2.6 years) completed three testing session with a break period of at least 2 days. During each session, postural control was assessed during two 30-s trials of bipedal stance with eyes close before and after the fatigue protocol. Fatigue protocols were performed by 60% of their unfatigued Maximum Voluntary Contraction of unilateral ankle plantar flexors, bilateral lumbar extensors and bilateral neck extensors. One of the three fatigue protocols was performed on each session. The result showed that fatigue had a significant effect on COP velocity and it increase COP velocity but there was not found any difference in postural sway between muscle groups. Localized muscle fatigue caused deficits in postural control regardless of the location of fatigue. Authors suggest the possibility of the contributions of central mechanisms to postural deficits due to fatigue and it seems that difference was not between muscle groups due to central fatigue.

The aim of the current study was to compare lower urinary tract symptoms (LUTS), erectile dysfunction (ED), and quality of life (QoL) in poststroke and healthy men. Thirty poststroke men with stroke-related LUTS, and as controls, 96 healthy men participated in this controlled, cross-sectional study. Participants filled in the Danish Prostate Symptom Score (DAN-PSS-1) Questionnaire, the International Index of Erectile Function (IIEF-5), the 36-Item Short Form (SF-36), the Nocturia Quality-of-Life (N-QoL) Questionnaire. In the age group ≤55 years, comparing poststroke men with healthy controls both with LUTS, the results indicated DAN-PSS-1, total score median 13 (4-17) versus 3 (2-6), p = .05; IIEF-5 25 (14-25) versus 24 (23-25), p = .06; SF-12, total score 499 (360-679) versus 695 (644-734), p = .02; and N-QoL 98 (70-100) versus 96 (90-100), p = .65. In the age group >55 years, comparing poststroke men with healthy controls both with LUTS, the results indicated DAN-PSS-1, total score 13 (8-24) versus 5 (2-7), p < .01; IIEF-5 13 (5-20) versus 25 (24-25), p < .01; SF-36, total score 585 (456-718) versus 742 (687-772), p < .01; and N-QoL, total score 81 (66-95) versus 98 (80-100), p < .01. The results demonstrated that in age group above, but not below 55 years, poststroke men with LUTS had significantly higher frequency of severe and bothersome LUTS and ED than the healthy controls with LUTS, while QoL and N-QoL were significantly lower in comparison. It is recommended to identify and assess older poststroke men for LUTS, ED, and QoL.

Fall prevention has an indispensable role in enhancing life expectancy and quality of life among older adults. The first step to prevent falls is to devise reliable methods to identify individuals at high fall risk. The purpose of the current study was to assess alterations in local postural muscle and central sensory balance control mechanisms due to low-frequency externally applied vibration among elders at high fall risk, in comparison with healthy controls, as a potential tool for assessing fall risk. Three groups of participants were recruited: healthy young (n = 10; age = 23 ± 2 years), healthy elders (n = 10; age = 73 ± 3 years), and elders at high fall risk (n = 10; age = 84 ± 9 years). Eyes-open and eyes-closed upright standing balance performance was measured with no vibration, 30 Hz, and 40 Hz vibration of Gastrocnemius muscles. When vibratory stimulation was applied, changes in local-control performance manifested significant differences among the groups (p < 0.01). On average between conditions, we observed 97% and 92% less change among high fall risk participants when compared to healthy young and older adults, respectively. On the other hand, vibration-induced changes in the central-control performance were not significant between groups (p ≥ 0.19). Results suggest that local-control deficits are responsible for balance behavior alterations among elders at high fall risk and healthy individuals. This observation may be attributable to deterioration of short-latency reflexive loop in elders at high fall risk. On the other hand, we could not ascribe the balance alterations to problems related to central nervous system performance or long-latency responses. Copyright © 2018 Elsevier Ltd.

Although deficits in facial affect processing have been reported in schizophrenia as well as in borderline personality disorder (BPD), these disorders have not yet been directly compared on facial affect labeling. Using degraded stimuli portraying neutral, angry, fearful and angry facial expressions, we hypothesized more errors in labeling negative facial expressions in patients with schizophrenia compared to healthy controls. Patients with BPD were expected to have difficulty in labeling neutral expressions and to display a bias towards a negative attribution when wrongly labeling neutral faces. Patients with schizophrenia (N = 57) and patients with BPD (N = 30) were compared to patients with somatoform disorder (SoD, a psychiatric control group; N = 25) and healthy control participants (N = 41) on facial affect labeling accuracy and type of misattributions. Patients with schizophrenia showed deficits in labeling angry and fearful expressions compared to the healthy control group and patients with BPD showed deficits in labeling neutral expressions compared to the healthy control group. Schizophrenia and BPD patients did not differ significantly from each other when labeling any of the facial expressions. Compared to SoD patients, schizophrenia patients showed deficits on fearful expressions, but BPD did not significantly differ from SoD patients on any of the facial expressions. With respect to the type of misattributions, BPD patients mistook neutral expressions more often for fearful expressions compared to schizophrenia patients and healthy controls, and less often for happy compared to schizophrenia patients. These findings suggest that although schizophrenia and BPD patients demonstrate different as well as similar facial affect labeling deficits, BPD may be associated with a tendency to detect negative affect in neutral expressions.

More than a decade of research has characterized the families of individuals with bulimia and bulimia anorexia (Anorexia Nervosa, Binge/Purging Type) as less expressive, less cohesive, and experiencing more conflicts than normal control families. This two-part study investigated variables believed more directly related to disturbed eating and bulimia as contributing to a "family climate for eating disorders." In Study 1. a nonclinical sample of 324 women who had just left home for college and a sample of 121 mothers evaluated their families. Principal-components analyses revealed the same factor structure for both students and mothers, with Family Body Satisfaction, Family Social Appearance Orientation, and Family Achievement Emphasis loading together, representing the hypothesized family climate for eating disorders: the remaining variables loaded with the more traditional family process variables (conflict, cohesion, expressiveness), representing a more general family dysfunction. As predicted, the family climate for eating disorders factor score was a more powerful predictor of disturbed eating. Study 2 extended these findings into a clin ical population, examining whether the family climate for eating disorders variables would distinguish individuals with bulimia from both depressed and healthy controls. Groups of eating-disordered patients (n = 40) and depressed (n = 17) and healthy (n = 27) controls completed family measures. The eating-disordered group scored significantly higher on family climate variables than control groups. Family process variables distinguished clinical groups (depressed and eating disordered) from healthy controls, but not from one another. Controlling for depression removed group differences on family process variables, but family climate variables continued to distinguish the eating-disordered group from both control groups. Indications for further research are discussed.

Despite a growing literature on the benefits of gratitude for adjustment to chronic illness, little is known about gratitude in medical populations compared to healthy populations, or the degree to which potential deficits in gratitude might impact quality of life. The purpose of the present study was to (1) examine levels of gratitude and quality of life in fibromyalgia patients and healthy controls and (2) consider the role of gratitude in explaining quality of life differences between fibromyalgia patients and healthy controls. Participants were 173 fibromyalgia patients and 81 healthy controls. All participants completed measures of gratitude, quality of life, and socio-demographics. Although gratitude was positively associated with quality of life, levels of gratitude and quality of life were lower in the fibromyalgia sample relative to the healthy controls. This difference in gratitude partially mediated differences in quality of life between the two groups after controlling for socio-demographic variables. Our findings suggest that gratitude is a valuable positive psychological trait for quality of life in people with fibromyalgia. Interventions to improve gratitude in this patient population may also bring enhancement in quality of life.

Blastocystis is a single-celled intestinal parasite commonly found in humans and a broad range of animals all over the world. In humans, its role in health and disease remains unsettled. The aim of our study was to investigate the distribution of Blastocystis and Blastocystis subtypes (ST) in patients with inflammatory bowel disease (IBD) and control subjects. A total of 71 stool samples were collected from IBD patients, 69 and 2 of whom had ulcerative colitis (UC) and Crohn's Disease (CD), respectively. Moreover, 166 stool samples from healthy subjects were included as control samples. All stool samples were cultivated, and 550-bp fragments of the small subunit ribosomal RNA gene was amplified from Blastocystis-positive cultures. All PCR-positive samples were sequenced. Blastocystis was observed in 9 (12.67%) and 35 (21.1%) IBD patients and healthy controls, respectively. There was no statistically significant correlation between IBD and presence of Blastocystis (P = 0.147). There was a statistically significant correlation between age and Blastocystis colonization in the IBD group (P < 0.05), but not among healthy controls. No significant correlation between gender and colonization was observed. ST1 and ST3 were obtained from 1 (12.5%) and 7 (87.5%) IBD patients, respectively, while in the healthy control group, subtypes 1, 2, and 3 were found in 14 (40%), 12 (34.28%), and 9 (25.72%), respectively. Phylogenetic analysis showed no variation in the distribution of subtypes nor intra-subtype genetic diversity between samples acquired from IBD patients and healthy controls. This study showed a trend towards a lower prevalence of Blastocystis in IBD patients than in control subjects. ST3 sequences isolated from IBD patients and control individuals did not appear to differ genetically.

While previous studies on the MMPI-2 in patients with schizophrenia and depression have used mixed samples of both early stage and chronic psychiatric patients. Here, it is investigated whether chronicity itself might have a differential effect on the MMPI-2 profiles of these patients and whether demoralization 'associated with long-term illness' affects the scales of the MMPI-2. Thirty long-term patients with schizophrenia, 30 long-term patients with depression, and 30 healthy participants completed the MMPI-2. Groups were compared on Clinical Scales and on the Restructured Clinical (RC) Scales. Patients with schizophrenia differed from patients with depression on 14 MMPI-2 scales and from healthy controls on 10 scales, generally showing mean UT-scores < 65, indicating a subjective experience of (near) normal functioning. Patients with depression differed from healthy controls on 17 scales mostly with UT-scores > 65, indicating impaired functioning. Demoralization was higher in patients with depression than in patients with schizophrenia and both psychiatric groups differed from the healthy control group. It is concluded that long-term patients with depression show impaired functioning and high demoralization, while long-term patients with schizophrenia surprisingly show near normal functioning and less demoralization. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

To study the effects of school lessons about healthy food on adolescents' self-reported beliefs and behaviour regarding the purchase and consumption of soft drinks, water and extra foods, including sweets and snacks. The lessons were combined with the introduction of lower-calorie foods, food labelling and price reductions in school vending machines. A cluster-randomized controlled design was used to allocate schools to an experimental group (i.e. lessons and changes to school vending machines) and a control group (i.e. 'care as usual'). Questionnaires were used pre-test and post-test to assess students' self-reported purchase of extra products and their knowledge and beliefs regarding the consumption of low-calorie products. Secondary schools in the Netherlands. Twelve schools participated in the experimental group (303 students) and fourteen in the control group (311 students). The students' mean age was 13.6 years, 71.5% were of native Dutch origin and mean BMI was 18.9 kg/m(2). At post-test, the experimental group knew significantly more about healthy food than the control group. Fewer students in the experimental group (43%) than in the control group (56%) reported bringing soft drinks from home. There was no significant effect on attitude, social norm, perceived behavioural control and intention regarding the consumption of low-calorie extra products. The intervention had limited effects on students' knowledge and self-reported behaviour, and no effect on their beliefs regarding low-calorie beverages, sweets or snacks. We recommend a combined educational and environmental intervention of longer duration and engaging parents. More research into the effects of such interventions is needed.

Previous studies examining the multifidus fiber characteristics among low back pain (LBP) patients have not considered the variable of physical activity. The present study sought to investigate the muscle fiber size and type distribution of the lumbar multifidus muscle among LBP patient groups with different physical activity levels and healthy controls. Sixty-four patients were assigned to one of three groups named according to the physical activity level, determined for each patient by the International Physical Activity Questionnaire. These were low (LPA), medium (MPA) and high (HPA) physical activity groups. A control group comprising of 17 healthy individuals was also recruited. Muscle biopsy samples were obtained from the multifidus muscle at the level L4-L5. contrast with the control group, LBP patient groups showed a significantly higher Type II fiber distribution as well as reduced diameter in both fiber types (P<0.05). The physical activity level did not have an effect on multifidus characteristics since no significant differences were observed in fiber type and diameter (P>0.05) among LPA, MPA and HPA patient groups. Various pathological conditions were detected which were more pronounced in LBP groups compared to the control (P<0.05). Males had a larger fiber diameter compared to females for both fiber types (P<0.05). The results showed that the level of physical activity did not affect muscle fiber size and type distribution among LBP patients groups. These findings suggest that not only inactivity but also high physical activity levels can have an adverse effect on the multifidus muscle fiber characteristics.

to test the effectiveness of breast feeding (BF), music therapy (MT), and combined breast feeding and music therapy (BF+MT) on pain relief in healthy-term neonates during heel lance. randomised controlled trial. in the postpartum unit of one university-affiliated hospital in China from August 2013 to February 2014. among 288 healthy-term neonates recruited, 250 completed the trial. All neonates were undergoing heel lancing for metabolic screening, were breast fed, and had not been fed for the previous 30 minutes. all participants were randomly assigned into four groups - BF, MT, BF+MT, and no intervention - with 72 neonates in each group. Neonates in the control group received routine care. Neonates in the other three intervention groups received corresponding interventions five minutes before the heel lancing and throughout the whole procedure. Neonatal Infant Pain Scale (NIPS), latency to first cry, and duration of first crying. mean changes in NIPS scores from baseline over time was dependent on the interventions given. Neonates in the BF and combined BF+MT groups had significantly longer latency to first cry, shorter duration of first crying, and lower pain mean score during and one minute after heel lance, compared to the other two groups. No significant difference in pain response was found between BF groups with or without music therapy. The MT group did not achieve a significantly reduced pain response in all outcome measures. BF could significantly reduce pain response in healthy-term neonates during heel lance. MT did not enhance the effect of pain relief of BF. healthy-term neonates should be breast fed to alleviate pain during heel lance. There is no need for the additional input of classical music on breast feeding in clinic to relieve procedural pain. Nurses should encourage breast feeding to relieve pain during heel lance.

To study features of brain gray matter injury in cerebral infarction patients and intervention of scalp acupuncture by using voxel-based morphology. A total of 16 cerebral infarction patients were recruited in this study, and assigned to the scalp acupuncture group and the control group, 8 in each group. Another 16 healthy volunteers were recruited as a normal group. All patients received scanning of T1 structure. Images were managed using VBM8 Software package. Difference of the gray matter structure was compared among the scalp acupuncture group, the control group, and the healthy volunteers. Compared with healthy volunteers, gray matter injury of cerebral infarction patients mainly occurred in 14 brain regions such as cingulate gyrus, precuneus, cuneus, anterior central gyrus, insular lobe, and so on. They were mainly distributed in affected side. Two weeks after treatment when compared with healthy volunteers, gray matter injury of cerebral infarction patients in the scalp acupuncture group still existed in 8 brain regions such as bilateral lingual gyrus, posterior cingulate gyrus, left cuneus, right precuneus, and so on. New gray matter injury occurred in lingual gyrus and posterior cingulate gyrus. Two weeks after treatment when compared with healthy volunteers, gray matter injury of cerebral infarction patients in the control group existed in 23 brain regions: bilateral anterior cingulum, caudate nucleus, cuneate lobe, insular lobe, inferior frontal gyrus, medial frontal gyrus, precuneus, paracentral lobule, superior temporal gyrus, middle temporal gyrus, lingual gyrus, right postcentral gyrus, posterior cingulate gyrus, precentral gyrus, middle frontal gyrus, and so on. New gray matter injury still existed in 9 cerebral regions such as lingual gyrus, posterior cingulate gyrus, postcentral gyrus, and so on. Brain gray matter structure is widely injured after cerebral infarction. Brain gray matter volume gradually decreased as time went by. Combined use of scalp acupuncture might inhibit the progression of gray matter injury more effectively.

P wave dispersion (Pd), defined as the difference between the maximum and the minimum P wave duration, has been associated with anxiety. Thus, we wondered whether Pd in hypochondriasis which is associated with anxiety differed from that in healthy controls. Pd was measured in 30 hypochondriac patients and same number of physically and mentally healthy age- and gender-matched controls. Hamilton Depression Rating (HDRS) and Hamilton Anxiety Rating Scales (HARS) were scored. The heart rate and left atrium (LA) sizes were not significantly different between groups. However, both Pmax and Pmin values of the patients were significantly higher than those of healthy controls. As for the main variable investigated in the present study, the corrected Pd was significantly longer in the patient group compared to control group. On the basis of this study, we can conclude that Pd may be related to hypochondriasis though our sample is too small to allow us to obtain a clear conclusion. Future studies with larger sample evaluating the effects of treatment are required. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Attention-deficit hyperactivity disorder (ADHD) is one of the most prevalent childhood psychiatric disorder, it affects around 3-12% of the children. ADHD is associated with numerous social and emotional impairments. Quality of life (QoL) studies of children with ADHD established low QoL in the most cases. Our aim was to examine QoL of children with ADHD according to the following aspects: age, children's self-report and parentproxy report, and we also would like to compare them with healthy control group along several dimensions of QoL. The clinical group consist of a treatmant naive group of children with ADHD, who were just diagnosed in the Vadaskert Hospital. The healthy control group consist of children from elementary schools. The children of control group do not have ADHD and do not stand under psychological or psychiatrical treatment. In our study we applied Mini International Neuropsychiatric Interview Kid and Intervertat Lebensqualitat Kindern und Jugendlichen questionare. Compared children with ADHD to healthy control group they have significantly lower QoL at many areas (school, peer realtions, generally) due their self report. By parent's proxy report children with ADHD have lower QoL according to all of the QoL domains. Parents of children with ADHD reported significantly lower QoL for their children in the most areas (school, family, peer realtion, mental state, generally) then the affected children. Adolescent with ADHD have lower QoL in 3 domains (school, peer relations, generally) than children with ADHD, while children with ADHD have lower QoL in one dimension (being alone) compared with adolescents with ADHD. Based on our results children with ADHD compared to healthy control group have lower QoL in many dimensions and there are age-related differences in the assessment of QoL. Additionally, our study draw the attention to the differences of QoL assessment between children and parents.

The burden of amyloid β is greater in patients with dementia with Lewy bodies than in those with Parkinson disease dementia, and an increased amyloid β load is closely related to a higher incidence of cerebral microbleeds. Here, we investigated the prevalence and topography of cerebral microbleeds in patients with dementia with Lewy bodies and those with Parkinson disease dementia to examine whether cerebral microbleeds are more prevalent in patients with dementia with Lewy bodies than in those with Parkinson disease dementia. The study population consisted of 42 patients with dementia with Lewy bodies, 88 patients with Parkinson disease dementia, and 35 controls who underwent brain MR imaging with gradient recalled-echo. Cerebral microbleeds were classified as deep, lobar, or infratentorial. The frequency of cerebral microbleeds was significantly greater in patients with dementia with Lewy bodies (45.2%) than in those with Parkinson disease dementia (26.1%) or in healthy controls (17.1%; P = .017). Lobar cerebral microbleeds were observed more frequently in the dementia with Lewy bodies group (40.5%) than in the Parkinson disease dementia (17%; P = .004) or healthy control (8.6%; P = .001) group, whereas the frequencies of deep and infratentorial cerebral microbleeds did not differ among the 3 groups. Logistic regression analyses revealed that, compared with the healthy control group, the dementia with Lewy bodies group was significantly associated with the presence of lobar cerebral microbleeds after adjusting for age, sex, nonlobar cerebral microbleeds, white matter hyperintensities, and other vascular risk factors (odds ratio, 4.39 [95% CI, 1.27-15.25]). However, compared with the healthy control group, the Parkinson disease dementia group was not significantly associated with lobar cerebral microbleeds. This study showed that patients with dementia with Lewy bodies had a greater burden of cerebral microbleeds and exhibited a lobar predominance of cerebral microbleeds than did patients with Parkinson disease dementia. © 2015 by American Journal of Neuroradiology.

Cognitive deficits of executive functions and decision-making in obsessive-compulsive disorder.

The nature of cognitive deficits in obsessive-compulsive disorder (OCD) is characterized by contradictory findings in terms of specific neuropsychological deficits. Selective impairments have been suggested to involve visuospatial memory, set shifting, decision-making and response inhibition. The aim of this study was to investigate cognitive deficits in decision-making and executive functioning in OCD. It was hypothesized that the OCD patients would be less accurate in their responses compared to the healthy controls in rational decision-making on a version of the Cambridge gambling task (CGT) and on the color-word interference test and on a version of the Tower of Hanoi test (tower test) of executive functioning. Thirteen participants with OCD were compared to a group of healthy controls (n = 13) matched for age, gender, education and verbal IQ. Results revealed significant differences between the OCD group and the healthy control group on quality of decision-making on the CGT and for achievement score on the tower test. On these two tasks the OCD group performed worse than the healthy control group. The symptom-dimension analysis revealed performance differences where safety checking patients were impaired on the tower test compared to contamination patients. Results are discussed in the framework of cognition and emotion processing and findings implicate that OCD models should address, specifically, the interaction between cognition and emotion. Here the emotional disruption hypothesis is forwarded to account for the dysfunctional behaviors in OCD. Further implications regarding methodological and inhibitory factors affecting cognitive information processing are highlighted. © 2013 The Scandinavian Psychological Associations.

It was recently shown that niacin prevents the obesity-induced type I to type II fiber switching in skeletal muscle of obese rats and favors the development of a more oxidative metabolic phenotype and thereby increases whole body utilization of fatty acids. Whether niacin also causes type II to type I fiber switching in skeletal muscle of healthy rats has not been investigated yet. Thus, the present study aimed to investigate whether niacin supplementation influences fiber distribution and metabolic phenotype of different skeletal muscles with a distinct type I-to-type II fiber ratio in healthy rats. Twenty-four male, 10-week-old Sprague-Dawley rats were randomly assigned into two groups of 12 rats each and fed either a control diet with 30 mg supplemented niacin/kg diet (control group) or a high-niacin diet with 780 mg supplemented niacin/kg diet (high-niacin group). After 27 days of treatment, the percentage number of type I fibers in rectus femoris, gastrocnemius, and tibialis anterior muscles was 5-10% greater in the niacin group than in the control group, but did not differ between groups in soleus and vastus intermedius muscles. Transcript levels of genes encoding transcription factors regulating fiber switching, fiber-specific myosin heavy chain isoforms, and proteins involved in fatty acid utilization, oxidative phosphorylation, and angiogenesis did not differ between groups. The results show that niacin has only negligible effects on fiber distribution and its regulation as well as the metabolic phenotype of skeletal muscle in healthy rats.

Previous meta-analysis revealed that mismatch negativity(MMN) amplitude decreased in patients with schizophrenia compared with healthy controls (Cohen's d, d about 1), leading to the possibility of mismatch negativity being used as a biomarker for schizophrenia. However, it is unknown whether MMN is reliably changed in Chinese patients. It is necessary to carry out a meta-analysis on MMN of Han Chinese patients with schizophrenia. To investigate whether MMN could be used as a biomarker for Han Chinese patients with schizophrenia. A literature search was conducted to identify clinical trials on MMN in Han Chinese schizophrenia patients published before May 8, 2017, by searching the Chinese language databases CNKI, WanFang Data, VIP Data and PubMed. The effects of MMN deficits were evaluated for MMN amplitude by calculating standard mean difference (SMDs) between schizophrenia patient groups and healthy control groups. A total of 11 studies were included in the analysis. The total quality of all the studies were more than 6 as evaluated by Newcastle-Ottawa Scale (NOS). Meta-analysis of data from these studies had a pooled sample of 432 patients with schizophrenia and 392 healthy controls. There exists significant MMN deficit in schizophrenia patients compared to healthy controls (Cohen's d =1.004). When studies were excluded due to heterogeneity, the pooled effect size of the MMN differences between the patient group and healthy controls dropped to 0.79 (Cohen's d =0.79). Subgroup analysis showed that MMN amplitude deficits of schizophrenia over three years had the pooled effect size of 0.95, and less than three years had the pooled effect size of 0.77. Publication bias conducted via Egger regression test ( t = 1.83; p = 0.101), suggested that there was no publication bias. The effect size of MMN amplitude between Chinese patients with schizophrenia and healthy controls is consistent with other meta-analyses published on this topic, suggesting that Han Chinese patients with schizophrenia also exhibited MMN deficits.

In healthy conditions, group-level fMRI resting state analyses identify ten resting state networks (RSNs) of cognitive relevance. Here, we aim to assess the ten-network model in severely brain-injured patients suffering from disorders of consciousness and to identify those networks which will be most relevant to discriminate between patients and healthy subjects. 300 fMRI volumes were obtained in 27 healthy controls and 53 patients in minimally conscious state (MCS), vegetative state/unresponsive wakefulness syndrome (VS/UWS) and coma. Independent component analysis (ICA) reduced data dimensionality. The ten networks were identified by means of a multiple template-matching procedure and were tested on neuronality properties (neuronal vs non-neuronal) in a data-driven way. Univariate analyses detected between-group differences in networks' neuronal properties and estimated voxel-wise functional connectivity in the networks, which were significantly less identifiable in patients. A nearest-neighbor "clinical" classifier was used to determine the networks with high between-group discriminative accuracy. Healthy controls were characterized by more neuronal components compared to patients in VS/UWS and in coma. Compared to healthy controls, fewer patients in MCS and VS/UWS showed components of neuronal origin for the left executive control network, default mode network (DMN), auditory, and right executive control network. The "clinical" classifier indicated the DMN and auditory network with the highest accuracy (85.3%) in discriminating patients from healthy subjects. FMRI multiple-network resting state connectivity is disrupted in severely brain-injured patients suffering from disorders of consciousness. When performing ICA, multiple-network testing and control for neuronal properties of the identified RSNs can advance fMRI system-level characterization. Automatic data-driven patient classification is the first step towards future single-subject objective diagnostics based on fMRI resting state acquisitions. Copyright © 2013 Elsevier Ltd.

Knee joint pain and reduced quadriceps strength are cardinal symptoms in many knee pathologies. In people with painful knee pathologies, quadriceps exercise reduces pain, improves physical function, and increases muscle strength. A general assumption is that pain compromises muscle function and thus may prevent effective rehabilitation. This study evaluated the effects of experimental knee joint pain during quadriceps strength training on muscle strength gain in healthy individuals. Twenty-seven healthy untrained volunteers participated in a randomized controlled trial of quadriceps strengthening (3 times per week for 8 weeks). Participants were randomized to perform resistance training either during pain induced by injections of painful hypertonic saline (pain group, n = 13) or during a nonpainful control condition with injection of isotonic saline (control group, n = 14) into the infrapatellar fat pad. The primary outcome measure was change in maximal isokinetic muscle strength in knee extension/flexion (60, 120, and 180 degrees/second). The group who exercised with pain had a significantly larger improvement in isokinetic muscle strength at all angular velocities of knee extension compared to the control group. In knee flexion there were improvements in isokinetic muscle strength in both groups with no between-group differences. Experimental knee joint pain improved the training-induced gain in muscle strength following 8 weeks of quadriceps training. It remains to be studied whether knee joint pain has a positive effect on strength gain in patients with knee pathology. Copyright © 2012 by the American College of Rheumatology.

Recently it has been claimed that infants with congenital muscular torticollis (CMT) are at risk of a delay in early motor milestones. The aim of the present study was to investigate whether infants with CMT are indeed at risk in comparison with a control group of healthy infants. A second aim was to investigate whether the time spent in a prone position and plagiocephaly had any influence on motor development. Eighty-two infants with CMT (35 females and 47 males) were compared with 40 healthy infants (18 females and 22 males). Motor development was assessed with the Alberta Infant Motor scale (AIMS). Multiple regression showed that infants in the CMT group had a significantly lower AIMS score than the control group at 2 months (p=0.03) and 6 months of age (p=0.05). Infants who spent at least three occasions daily in a prone position when awake had significantly higher AIMS scores than infants who spent less time prone at 2 months (p=0.001), 6 months (p<0.001), and 10 months of age (p<0.001). The CMT group achieved early motor milestones significantly later than the control group until the age of 10 months, but the risk of delay seems to be more strongly associated with little or no time prone when awake than with CMT.

To compare the topographic and biomechanical properties of corneas in eyes of patients with ichthyosis vulgaris (IV) and eyes of healthy individuals. Thirty healthy individuals (control group) and 30 patients with IV (study group) were enrolled in this prospective study. Topographic measurements, including keratometry values, irregularity, and surface asymmetry index in the right eye of each participant were obtained using Scheimpflug camera with a Placido disc topographer (Sirius). Corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated intraocular pressure (IOPcc) and Goldman-related intraocular pressure (IOPg) were measured using the Reichert Ocular Response Analyzer (ORA). Central corneal thickness (CCT) was also measured with ultrasonic pachymetry and the Sirius corneal topography system. Topographic parameters were not significantly different between both groups (p>0.05). Although mean CH was not significantly different between the groups, the CRF was significantly lower in patients with IV (p=0.249 and p=0.005, respectively). The CCT was significantly lower in patients with IV compared to healthy controls (p<0.001). The IOPg and IOPcc were significantly lower in the patients with ichthyosis than in healthy controls (p=0.001 and p=0.004, respectively). The study demonstrated that while the eyes of patients with IV had corneal topographic findings and corneal hysteresis similar to those of healthy controls, some of corneal biomechanical properties such CRF and CCT and IOP values such as IOPg and IOPcc were significantly lower in patients with IV. These results should be taken into account when planning a corneal refractive surgery and glaucoma screening for patients with IV. Copyright © 2012 British Contact Lens Association.

We assessed the effectiveness of a 6-month healthy lifestyle intervention, on pain intensity in patients with chronic low back pain who were overweight or obese. We conducted a pragmatic randomised controlled trial, embedded within a cohort multiple randomised controlled trial of patients on a waiting list for outpatient orthopaedic consultation at a tertiary hospital in NSW, Australia. Eligible patients with chronic low back pain (>3 months in duration) and body mass index ≥27 kg/m and <40 kg/m were randomly allocated, using a central concealed random allocation process, to receive advice and education and referral to a 6-month telephone-based healthy lifestyle coaching service, or usual care. The primary outcome was pain intensity measured using an 11-point numerical rating scale, at baseline, 2 weeks, and monthly for 6 months. Data analysis was by intention-to-treat according to a prepublished analysis plan. Between May 13, 2015, and October 27, 2015, 160 patients were randomly assigned in a 1:1 ratio to the intervention or usual care. We found no difference between groups for pain intensity over 6 months (area under the curve, mean difference = 6.5, 95% confidence interval -8.0 to 21.0; P = 0.38) or any secondary outcome. In the intervention group, 41% (n = 32) of participants reported an adverse event compared with 56% (n = 45) in the control group. Our findings show that providing education and advice and telephone-based healthy lifestyle coaching did not benefit patients with low back pain who were overweight or obese, compared with usual care. The intervention did not influence the targeted healthy lifestyle behaviours proposed to improve pain in this patient group.

To define regional grey-matter abnormalities in schizophrenia patients with poor insight (Insight(-)), relative to patients with preserved clinical insight (Insight(+)), and healthy controls. Forty stable schizophrenia outpatients (20 Insight(-) and 20 Insight(+)) and 20 healthy controls underwent whole brain magnetic resonance imaging (MRI). Insight in all patients was assessed using the Birchwood Insight Scale (BIS; a self-report measure). The two patient groups were pre-selected to match on most clinical and demographic parameters but, by design, they had markedly distinct BIS scores. Voxel-based morphometry employed in SPM8 was used to examine group differences in grey matter volumes across the whole brain. The three participant groups were comparable in age [F(2,57) = 0.34, P = 0.71] and the patient groups did not differ in age at illness onset [t(38) = 0.87, P = 0.39]. Insight(-) and Insight(+) patient groups also did not differ in symptoms on the Positive and Negative Syndromes scale (PANSS): Positive symptoms [t(38) = 0.58, P = 0.57], negative symptoms [t(38) = 0.61, P = 0.55], general psychopathology [t(38) = 1.30, P = 0.20] and total PANSS scores [t(38) = 0.21, P = 0.84]. The two patient groups, as expected, varied significantly in the level of BIS-assessed insight [t(38) = 12.11, P < 0.001]. MRI results revealed lower fronto-temporal, parahippocampal, occipital and cerebellar grey matter volumes in Insight(-) patients, relative to Insight(+) patients and healthy controls (for all clusters, family-wise error corrected P < 0.05). Insight(+) patient and healthy controls did not differ significantly (P > 0.20) from each other. Our findings demonstrate a clear association between poor clinical insight and smaller fronto-temporal, occipital and cerebellar grey matter volumes in stable long-term schizophrenia patients.

Sarcoidosis is an important diagnostic consideration in patients with ventricular tachycardia (VT) of unknown origin. The clinical course of VT as the primary presentation in patients with sarcoidosis is mostly unknown. This study aimed to investigate the incidence of life-threatening VT and mortality during long term follow-up in patients with sarcoidosis. We analyzed the epidemiological features of sarcoidosis in Taiwan using the National Health Insurance Research Database from 2000 to 2004. Patients with sarcoidosis were identified, and healthy controls without prior histories of structural heart disease were matched with a 1:1 propensity-score to the sarcoidosis group. The risk of life-threatening VT and mortality with sarcoidosis was analyzed. A total of 2237 sarcoidosis cases were enrolled with a matching number of healthy controls, and the baseline characteristics between the two groups were similar. After a mean follow-up of 11.4±2.15years (IQR: 12, 11.3-12), the VT incidence in the sarcoidosis group was higher than in healthy controls (0.94% [85 per 100,000 person-year] in the sarcoidosis group, and 0.09% [8 per 100,000 person-year] in healthy controls). After a multivariate adjustment including the sex, age, and other comorbidities, the VT risk was still higher in the sarcoidosis group (hazard ratio: 12.7, 95% confidence interval: 2.82-56.9; P<0.001). The risk of defibrillator implantations for secondary prevention, cardiovascular death, and total mortality between the groups was equivalent. Sarcoidosis may increase the predisposition to ventricular arrhythmias with a cumulative incidence of 0.94% during a very long term follow-up of nearly 10years from initially diagnosing sarcoidosis.

Coping with stress plays a vital role in the adjustment of adolescents with diabetes. The majority of studies in this area leave out the control group, limiting their power to make inferences about specificity vs. similarity of coping strategies used by these adolescents. The aims of this study were: (1) To compare coping strategies in adolescents with diabetes and healthy adolescents; (2) To compare coping strategies in girls and boys with diabetes; (3) To determine whether there is a relationship between adolescents' coping strategies and their mothers' coping styles. Adolescents (12-17 years old) with Type 1 diabetes (n = 51) were compared with a control group of healthy secondary school students (n = 56) by means of a self-reported questionnaire measuring coping strategies (Adolescence Coping Checklist). Mothers of these adolescents (n = 107) completed the Coping Inventory for Stressful Situations, measuring 3 coping styles. Diabetic adolescents used the 'seek professional help' strategy more often than their healthy peers. The girls with diabetes reported using the 'investing in close friends' strategy more often than boys, while in the control group girls were also more likely to use "seeking social support", "seeking spiritual support", and "relaxing diversions" strategies. Mothers' emotion-oriented coping style predicted focus-oriented coping in adolescents with diabetes. In the non-diabetic group, mothers' task-oriented coping predicted seeking professional help, while mothers' avoidance-oriented coping predicted seeking spiritual support. The results demonstrated that: (1) the only differences in terms of coping strategies in adolescents with diabetes and healthy adolescents were found in seeking professional help; (2) gender differences in coping with stress were significantly smaller in adolescents with diabetes than in healthy adolescents, (3) mothers' coping styles were predictors of coping strategies in adolescents, albeit there were differences in that respect between adolescents with diabetes and healthy adolescents.

Evidence suggests that some aspects of schizophrenia can be induced in healthy volunteers through acute administration of the non-competitive NMDA-receptor antagonist, ketamine. In probabilistic inference tasks, patients with schizophrenia have been shown to ‘jump to conclusions’ (JTC) when asked to make a decision. We aimed to test whether healthy participants receiving ketamine would adopt a JTC response pattern resembling that of patients. The paradigmatic task used to investigate JTC has been the ‘urn’ task, where participants are shown a sequence of beads drawn from one of two ‘urns’, each containing coloured beads in different proportions. Participants make a decision when they think they know the urn from which beads are being drawn. We compared performance on the urn task between controls receiving acute ketamine or placebo with that of patients with schizophrenia and another group of controls matched to the patient group. Patients were shown to exhibit a JTC response pattern relative to their matched controls, whereas JTC was not evident in controls receiving ketamine relative to placebo. Ketamine does not appear to promote JTC in healthy controls, suggesting that ketamine does not affect probabilistic inferences. PMID:22389244

Anger plays a major role in psychodermatological diseases. Researchers have reported that anger and other psychological factors play a role in the etiology of chronic urticaria. This study aimed to examine symptoms of anger, anger-related behavioral patterns, thoughts associated with anger, situations that cause anger and experiences of interpersonal anger in patients with chronic spontaneous urticaria (CSU). The authors hypothesized that patients with CSU react to more situations with anger and experience more anger symptoms as compared to alopecia areata (AA) patients and healthy controls. The cohort study population consisted of literate adult patients aged <65 years that were diagnosed with CSU at the outpatient dermatology clinics of Başkent and Gazi University, Ankara, Turkey, between September 2011 and October 2012. The first control group included individuals without any physical or mental disorders and the second one included literate adult patients diagnosed with AA. The patients and controls were matched according to age, gender, and level of education. A sociodemographic data form, and the Hospital Anxiety and Depression Scale and Multi-Dimensional Anger Inventory were administered to the participants. Data were analyzed using SPSS v.17.0 for Windows. The primary outcome was to determine whether there was a relationship between anger and CSU. The CSU group consisted of 30 participants; AA group consisted of 30 participants; and the healthy group consisted of 39 participants. Anxiety and depression scores in the CSU group were significantly higher than those in the healthy control group. Symptoms of anger, situations that cause anger, and thoughts associated with anger were significantly more common in the CSU group compared to AA group and healthy group. More of the CSU patients were observed to respond with excessive anger to most situations, to have high levels of anxiety anger and passive aggressive interpersonal relationships.

Dèjà-vù (DV) can occur as a seizure of mesial temporal lobe epilepsy (MTLE) and in almost 80% of healthy individuals. The remarkable similarity between epileptic DV and DV in healthy individuals raises the possibility that DV might sometimes be an ictal phenomenon in apparently normal individuals. Thus, we studied a group of healthy subjects versus individuals with benign MTLE (bMTLE) both experiencing DV. 63 individuals with epilepsy patients with bMTLE and 39 healthy controls at Catanzaro University were recruited. Participants completed the Inventory for Déjà Vu (DV) Experiences Assessment (IDEA) test, underwent awake and asleep electroencephalogram, MRI of the brain using a 3T scanner and whole brain voxel-based morphometry (VBM). bMTLE patients with DV and without DV were also matched for the presence of hippocampal sclerosis. Our controls had no history of neurological or psychiatric illness, epilepsy or history of febrile convulsions. Neurological and cognitive examinations were normal. Electroencephalographic procedures were unremarkable in all controls. In bMTLE group, the direct comparison of VBM between individuals with epilepsy with DV versus those without DV revealed abnormal anatomical changes in the left hippocampus, parahippocampal gyrus and visual cortex. The VBM of healthy controls with DV showed abnormal anatomical changes only in the left insular cortex. Our VBM results demonstrated different morphologic patterns in individuals with epilepsy and control subjects experiencing DV, involving the memory circuit in bMTLE patients and cerebral regions in the emotional network in healthy controls.

This study aimed to compare the prevalence of metabolic syndrome (MS) among inpatients with depressive disorders and matched healthy controls. One hundred fifty eight patients with depressive disorders and 52 age and gender matched healthy controls were assessed for the prevalence of MS using Common Criteria for MS. Prevalence of Metabolic syndrome among inpatients with depressive disorders was 44.3%, which was significantly higher than the healthy control group (17.3%). Increased waist circumference was the most common abnormality in both the groups. Prevalence of MS among patients with recurrent depression disorder (60.3%) was almost double that seen among those with first episode depression (32.6%). Compared to healthy controls, significantly greater proportion of patients with depressive disorders had increased blood pressure, abnormal fasting blood sugar, and HDL levels. Besides the prevalence of MS in 44.3% of patients with depressive disorders, another 46% of patients fulfilled one or two criteria of MS. Significant predictors of MS were being married, obese, greater age, higher weight, higher body mass index, and multiple episodes of depression. Nearly two-fifth of depressed patients have MS and another two-fifth of patients had one or two abnormalities in the MS criteria. The prevalence of MS among patients with depressive disorders is significantly higher than the healthy controls. Hence, patients with depressive disorders should be regularly evaluated for the presence of MS and other cardiovascular risk factors and appropriate management strategies must be instituted at the earliest.

Social factors may be of importance causally and act as maintenance factors in patients with anorexia nervosa. Oxytocin is a neuromodulatory hormone involved in social emotional processing associated with attentional processes. This study aimed to examine the impact of oxytocin on attentional processes to social faces representing anger, disgust, and happiness in patients with anorexia nervosa. A double-blind, placebo-controlled within-subject crossover design was used. Intranasal oxytocin or placebo followed by a visual probe detection task with faces depicting anger, disgust, and happiness was administered to 64 female subjects: 31 patients with anorexia nervosa and 33 control students. Attentional bias to the disgust stimuli was observed in both groups under the placebo condition. The attentional bias to disgust was reduced under the oxytocin condition (a moderate effect in the patient group). Avoidance of angry faces was observed in the patient group under the placebo condition and vigilance was observed in the healthy comparison group; both of these information processing responses were moderated by oxytocin producing an increase in vigilance in the patients. Happy/smiling faces did not elicit an attentional response in controls or the patients under either the placebo or oxytocin conditions. Oxytocin attenuated attentional vigilance to disgust in patients with anorexia nervosa and healthy controls. On the other hand, oxytocin changed the response to angry faces from avoidance to vigilance in patients but reduced vigilance to anger in healthy controls. We conclude that patients with anorexia nervosa appear to use different strategies/circuits to emotionally process anger from their healthy counterparts.

The attachment styles and parental bonding by 64 patients (M age = 43.2 yr., SD = 13.3) with Gastroesophageal Reflux Disease (GERD) were compared with those of 64 patients (M age = 42.2 yr., SD = 13.5) with Inflammatory Bowel Disease (IBD) and 126 Healthy participants (M age = 42.2 yr., SD = 12.1). Analysis of scores on the Attachment Style Questionnaire indicated insecure attachment in both the patient and control groups. The Parental Bonding scores indicated perceptions of Affectionless Control by parents in both patient groups. In particular, the mean Father-Protection subscale scores were significantly higher for in the GERD group than in the Healthy and IBD groups.

Regular physical exercise and healthy lifestyle can improve aerobic power of the elderly, although lung capacity gradually deteriorates with age. The aims of the study are: a) to evaluate the therapeutic effect of a treadmill exercise program on arterial blood oxygenation (SaO2), maximum oxygen consumption (VO2max) and maximum walking distance (MWD) in healthy elderly people; b) to examine the outcome of the program at a supervised short-term and at an unsupervised long-term. A prospective, not-randomized controlled intervention trial (NRCT) was conducted. Eighty participants were allocated into two homogeneous groups (training group, TG, n = 40; control group, CG, n = 40). Each group consisted of 20 men and 20 women. Pre-intervention measures of SaO2, VO2max and MWD were taken of each participant 1-week before the training program to establish the baseline. Also, during the training program, the participants were followed up at the 12, 30 and 48th week. The exercise program consisted of walking on a treadmill with fixed 0 % grade of inclination 3 times weekly for 48 weeks; the first 12 weeks were supervised and the remaining 36 weeks of the program were unsupervised. Participants in the control group were encouraged to walk twice a week during 45 min, and received standard recommendations for proper health. Related to the baseline, the SaO2, VO2max, and MWD is greater in the intervention group at the 12(th) (p <.001), 30(th) (p <.001) and 48(th) week (p <.001). Compared with the control group, there was also a significant improvement of SaO2, VO2max, and MWD valuesin the intervention group (p <.001) at the 12(th) (p <.001), 30(th) (p <.001) and 48(th) week (p <.001). Supervised intervention shows greater improvement of SaO2, VO2max, and MWD values than in the unsupervised one. These results show that performing moderate exercise, specifically walking 3 days a week, is highly recommended for healthy older people, improving aerobic power.

Cognitive decline is among the most feared treatment-related outcomes of older adults with cancer. The majority of older patients with breast cancer self-report cognitive problems during and after chemotherapy. Prior neuroimaging research has been performed mostly in younger patients with cancer. The purpose of this study was to evaluate longitudinal changes in brain volumes and cognition in older women with breast cancer receiving adjuvant chemotherapy. Women aged ≥ 60 years with stage I-III breast cancer receiving adjuvant chemotherapy and age-matched and sex-matched healthy controls were enrolled. All participants underwent neuropsychological testing with the US National Institutes of Health (NIH) Toolbox for Cognition and brain magnetic resonance imaging (MRI) prior to chemotherapy, and again around one month after the last infusion of chemotherapy. Brain volumes were measured using Neuroreader™ software. Longitudinal changes in brain volumes and neuropsychological scores were analyzed utilizing linear mixed models. A total of 16 patients with breast cancer (mean age 67.0, SD 5.39 years) and 14 age-matched and sex-matched healthy controls (mean age 67.8, SD 5.24 years) were included: 7 patients received docetaxel and cyclophosphamide (TC) and 9 received chemotherapy regimens other than TC (non-TC). There were no significant differences in segmented brain volumes between the healthy control group and the chemotherapy group pre-chemotherapy (p > 0.05). Exploratory hypothesis generating analyses focusing on the effect of the chemotherapy regimen demonstrated that the TC group had greater volume reduction in the temporal lobe (change = - 0.26) compared to the non-TC group (change = 0.04, p for interaction = 0.02) and healthy controls (change = 0.08, p for interaction = 0.004). Similarly, the TC group had a decrease in oral reading recognition scores (change = - 6.94) compared to the non-TC group (change = - 1.21, p for interaction = 0.07) and healthy controls (change = 0.09, p for interaction = 0.02). There were no significant differences in segmented brain volumes between the healthy control group and the chemotherapy group; however, exploratory analyses demonstrated a reduction in both temporal lobe volume and oral reading recognition scores among patients on the TC regimen. These results suggest that different chemotherapy regimens may have differential effects on brain volume and cognition. Future, larger studies focusing on older adults with cancer on different treatment regimens are needed to confirm these findings. ClinicalTrials.gov, NCT01992432 . Registered on 25 November 2013.

Little information is available regarding the extent of strategy use and factors that affect strategy use in amnestic mild cognitive impairment (aMCI). This study aimed to compare spontaneous strategy use and beliefs about the controllability of memory between aMCI and healthy older adult (HOA) samples and to explore the relationships between beliefs, strategy use, and memory performance for both groups. The aMCI and HOA groups each composed of 60 individuals matched for age and education. The Memory Controllability Inventory was used to assess control beliefs, and the extent of semantic clustering on a list-learning task provided a measure of spontaneous strategy use. The aMCI group endorsed lower control beliefs and demonstrated poorer semantic clustering and memory performance compared with the HOA group. Although strategy use partially mediated the control beliefs-memory performance relationship for the HOA group, this was not replicated for the aMCI group. Despite the weak relationship between control beliefs and strategy use, and control beliefs and memory performance for the aMCI group, the strong relationship between strategy use and memory performance provides impetus for further research into factors that can be used as a means of enhancing strategy use in interventions for aMCI.

Implicit associations of the self to concepts like “calm” have been shown to be weaker in persons with social anxiety than in non-anxious healthy controls. However, other implicit self associations, such as those to acceptance or rejection, have been less studied in social anxiety, and none of this work has been conducted with clinical samples. Furthermore, the importance of depression in these relationships has not been well investigated. We addressed these issues by administering two Implicit Association Tests (IATs; Greenwald, McGhee, & Schwartz, 1998), one examining the implicit association of self/other to anxiety/calmness and the other examining the association of self/other to rejection/acceptance, to individuals with generalized social anxiety disorder (SAD, n = 85), individuals with generalized SAD and a current or past diagnosis of major depressive disorder or current dysthymic disorder (n = 47), and non-anxious, non-depressed healthy controls (n = 44). The SAD and SAD-depression groups showed weaker implicit self-calmness associations than healthy controls, with the comorbid group showing the weakest self-calmness associations. The SAD-depression group showed the weakest implicit self-acceptance associations; no difference was found between non-depressed individuals with SAD and healthy controls. Post hoc analyses revealed that differences appeared to be driven by those with current depression. The SAD-only and SAD-depression groups did not differ in self-reported (explicit) social anxiety. The implications of these findings for the understanding of SAD-depression comorbidity and for the treatment of SAD are considered. PMID:24983794

To assess the effect of the solution-focused approach interview technique on overweight/obese adolescents' nutrition-exercise attitudes and behaviours. Obesity is a serious health problem for all age groups, particularly adolescents; therefore, it is important for adolescents to develop healthy nutrition habits and acquire exercise behaviours. Unless healthy nutrition-exercise behaviours are acquired, obesity can develop in adolescence, continue in adulthood. Focusing on solutions can be effective for overweight/obese adolescents to develop healthy nutrition-exercise behaviours. A pretest-post-test randomised controlled trial design was used. The study included 32 overweight/obese adolescents (16 for intervention group, 16 for control group) aged 12-13 years who attended a health centre and met the inclusion criteria. The solution-focused Approach interview technique was applied to the intervention group. Eight solution-focused interviews were conducted with each adolescent at 2-week intervals (interview length 30-45 min). For each group, anthropometric, metabolic measurement follow-ups were conducted in the first and sixth months. The data were evaluated using independent samples t test, Mann-Whitney U, Wilcoxon test, respectively, for normally, non-normally distributed variables. The categorical variables were compared using chi-square test. The value p < .05 was accepted to be statistically significant. The study concluded that the intervention group's healthy nutrition-exercise attitude and behaviour scale scores were higher in the sixth month follow-up; difference between the follow-ups was significant (p < .001). The study also showed that the intervention group lost 2.6-11 kg, while the control group gained 2.9-9 kg. A significant positive relationship was found between the nutrition-exercise attitude and behaviour scores. Eight interviews during 6 months were adequate for positive development of their nutrition-exercise attitudes and behaviours; significant decrease in their weight, BMI percentile, BMI-SDS values; and normal metabolic values. The solution-focused approach interview technique enabled overweight/obese adolescents' weight and blood glucose to be controlled against obesity. It helped them acquire healthy nutrition-exercise behaviours. Thus, it can be used as support for treatment of obesity in adolescents. © 2017 John Wiley & Sons Ltd.

It is not known whether patients with juvenile myoclonic epilepsy (JME) differ from healthy people in decision making under risk, i.e., when the decision-making context offers explicit information about options, probabilities, and consequences already from the beginning. In this study, we adopted the Game of Dice Task-Double to investigate decision making under risk in a group of 36 patients with JME (mean age 25.25/SD 5.29 years) and a group of 38 healthy controls (mean age 26.03/SD 4.84 years). Participants also underwent a comprehensive neuropsychological assessment focused on frontal executive functions. Significant group differences were found in tests of psychomotor speed and divided attention, with the patients scoring lower than the controls. Importantly, patients made risky decisions more frequently than controls. In the patient group, poor decision making was associated with poor executive control, poor response inhibition, and a short interval since the last seizure episode. Executive control and response inhibition could predict 42% of variance in the frequency of risky decisions. This study indicates that patients with JME with poorer executive functions are more likely to make risky decisions than healthy controls. Decision making under risk is of major importance in every-day life, especially with regard to treatment decisions and adherence to long-term medical therapy. Since even a single disadvantageous decision may have long-lasting consequences, this finding is of high relevance.

The present study was conducted to investigate the relationship between Mycoplasma pneumoniae (MP) infection and the risk of asthma among children by detecting the rate of MP immunoglobulin M (MP-IgM) and the eosinophil (EOS) count. A total of 139 asthmatic children were enrolled as the case group and assigned into three groups: Group A (aged <3 years, n=42), group B (aged 3-8 years, n=45) and group C (aged >8 years, n=52). Additionally, 115 healthy children were enrolled in the control group. Enzyme-linked immunosorbent assay was used to measure the MP-IgM-positive rate. EOS count was detected in the experimental and control groups by using a hemocytometer analyzer. A meta-analysis was performed by using the Comprehensive Meta-Analysis version 2.0 software. The positive rates of the MP-IgM and EOS count in the experimental group were significantly higher than those in control group (both P<0.001). Furthermore, the asthmatic children in group C had a higher MP-IgM-positive rate and EOS count as compared to those in groups A and B, respectively (all P<0.05). Results from groups A and B were not statistically significant (all P>0.05). The meta-analysis further confirmed that asthmatic children had a higher MP-IgM-positive rate as compared to the healthy controls (P<0.001). Age-stratified analysis revealed that the MP-IgM-positive rate in asthmatic children aged ≥8 and <8 years was significantly higher than that in the healthy controls (P=0.003 and P<0.001). Asthmatic children had a higher MP-IgM-positive rate and EOS count as compared with controls, suggesting that the MP infection may be closely associated with the risk of asthma. Additionally, the positive rate of MP-IgM may indicate an important biological marker in predicting the development of asthma.

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.

Background: As medication does not normalize outcomes of children with attention deficit hyperactivity disorder (ADHD), especially in real-life functioning, nonpharmacological methods are important to target this field. This randomized controlled clinical trial was designed to evaluate the effects of a comprehensive executive skill training program for school-aged children with ADHD in a relatively large sample. Methods: The children (aged 6–12 years) with ADHD were randomized to the intervention or waitlist groups. A healthy control group was composed of gender- and age-matched healthy children. The intervention group received a 12-session training program for multiple executive skills. Executive function (EF), ADHD symptoms, and social functioning in the intervention and waitlist groups were evaluated at baseline and the end of the final training session. The healthy controls (HCs) were only assessed once at baseline. Repeated measures analyses of variance were used to compare EF, ADHD symptoms, and social function between intervention and waitlist groups. Results: Thirty-eight children with ADHD in intervention group, 30 in waitlist group, and 23 healthy children in healthy control group were included in final analysis. At posttreatment, intervention group showed significantly lower Behavior Rating Inventory of Executive Function (BRIEF) total score (135.89 ± 16.80 vs. 146.09 ± 23.92, P = 0.04) and monitoring score (18.05 ± 2.67 vs. 19.77 ± 3.10, P = 0.02), ADHD-IV overall score (41.11 ± 7.48 vs. 47.20 ± 8.47, P < 0.01), hyperactivity-impulsivity (HI) subscale score (18.92 ± 5.09 vs. 21.93 ± 4.93, P = 0.02), and inattentive subscale score (22.18 ± 3.56 vs. 25.27 ± 5.06, P < 0.01), compared with the waitlist group. Repeated measures analyses of variance revealed significant interactions between time and group on the BRIEF inhibition subscale (F = 5.06, P = 0.03), working memory (F = 4.48, P = 0.04), ADHD-IV overall score (F = 21.72, P < 0.01), HI subscale score (F = 19.08, P < 0.01), and inattentive subscale score (F = 12.40, P < 0.01). Multiple-way analysis of variance showed significant differences on all variables of BRIEF, ADHD-rating scale-IV, and WEISS Functional Impairment Scale-Parent form (WFIRS-P) among the intervention and waitlist groups at posttreatment and HCs at baseline. Conclusions: This randomized controlled study on executive skill training in a relatively large sample provided some evidences that the training could improve EF deficits, reduce problematic symptoms, and potentially enhance the social functioning in school-aged children with ADHD.

The cerebral metabolic rate for glucose (CMRglc) was measured with positron emission tomography and [18F]2-fluoro-2-deoxy-D-glucose in 14 healthy subjects with Down's syndrome, 19 to 33 years old, and in six healthy Down's syndrome subjects over 35 years, two of whom were demented. Dementia was diagnosed from a history of mental deterioration, disorientation and hallucinations. All Down's syndrome subjects were trisomy 21 karyotype. CMRglc also was examined in 15 healthy men aged 20-35 years and in 20 healthy men aged 45-64 years. All subjects were at rest with eyes covered and ears plugged. Mean hemispheric CMRglc in the older Down's syndrome subjects was significantly less, by 23%, than in the young Down's syndrome group; statistically significant decreases in regional metabolism (rCMRglc) also were present in all lobar regions. Comparison of the younger control group with the older control group showed no difference in CMRglc or any rCMRglc (p greater than 0.05). Assessment of language, visuospatial ability, attention and memory showed significant reductions in test scores of the old as compared with the young Down's syndrome subjects. These results show that significant age differences in CMRglc and rCMRglc occur in Down's syndrome but not in healthy controls, and that, although only some older Down's syndrome subjects are demented, significant age reductions in neuropsychologic variables occur in all of them.

Aim To determine the age of development of bladder and bowel control and the frequency of enuresis, encopresis, and urinary infections in children with cerebral palsy. Methods The study included 45 children with cerebral palsy who regularly attended a rehabilitation center in Isparta, Turkey, and two groups of age- and sex-matched children, 37 siblings of the children with cerebral palsy and 37 healthy children. Demographic data and information on the age of development of total bladder and bowel control and presence of possible urinary symptoms in children were collected from their caregivers by use of a questionnaire. Frequency of enuresis and encopresis was estimated among the children aged ≥5 years. A mid-way urinary sample was obtained from 40, 22, and 21 children in the cerebral palsy, siblings, and healthy children, respectively. Results The mean age of nighttime bladder and bowel control development was 47 months (95% confidence interval [CI], 35-58) and 45 (36-55) months, respectively, for the children with cerebral palsy, 35 months (95% CI, 24-46) and 26 months (95% CI, 24-28), respectively, for their siblings, and 27 months (95% CI, 22-33) and 25 months (95% CI, 23-27) months, respectively, for the healthy children. Among the children aged ≥5 years, enuresis was present in 11 of 34 children with cerebral palsy, 7 of 30 siblings, and 4 of 30 healthy children (P = 0.200), whereas encopresis was present in 5 children with cerebral palsy, one sibling, and one healthy child. Constipation was significantly more present in chidlren with cerebral palsy than in other two groups (P<0.001). Urine culture was positive in 13 children with cerebral palsy, 1 sibling, and 2 healthy chidlren (P = 0.024). There were no significant differences in other urinary symptoms and laboratory findings among the three groups. Conclusion The children with cerebral palsy gained bladder and bowel control at older age in comparison with their siblings and healthy children. They also had more frequent enuresis and urinary infections. PMID:16625691

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.

To investigate the effect of a four-week consumption of a special Hungarian probiotic agent (Biofir) on the faecal microflora in human healthy subjects. The effect of Biofir with 10(6)/cm3 initial germs on the faecal microflora was studied in 120 healthy volunteers (71 females, 49 males). The traditional Russian type kefir was used as control. The various germ groups and pH values were determined in wk 2, 4 and 6. The number of all microbes increased during the 4-week probiotic treatment. The number of microbes increased 4.3-fold in the control group and 6.8-fold in Biofir-treated group. The probiotic kefir caused multiplication of the probiotic flora, meanwhile the undesired bacteria multiplied in the control group. No significant change of pH values of the faeces was found in both groups. The Hungarian probiotic kefir (Biofir) is capable of promoting multiplication of probiotic bacterial flora in the large bowel.

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

This study aims to investigate the serum adiponectin, interleukin (IL)-6 and oxidative stress in epilepsy patients who are refractory or non-refractory to treatments. The study comprised 31 refractory epilepsy, 29 well-controlled epilepsy patients and control group including 29 healthy individuals. The serum adiponectin, IL-6, total antioxidant status (TAS), total oxidant status levels (TOS) and oxidative stress index (OSİ) were determined. The mean serum adiponectin and TAS levels were significantly lower in the refractory epilepsy patients than in the healty controls, and mean IL-6, TOS and OSİ levels were significantly higher. The serum adiponectin, IL-6, TAS, TOS and OSI levels were not significantly different between the well-controlled epilepsy patients and the healthy controls. The mean serum IL-6 and oxidative stress levels in refractory epilepsy patients were higher and the serum adiponectin level was lower than the healthy control group. These findings may be associated with an increased risk of seizures, atherosclerosis and cardiovascular disease in refractory epilepsy patients. Copyright © 2018 British Epilepsy Association.

The study aimed to explore the gap of prevalence of healthy lifestyle behaviors including smoking cessation, quitting drinking, physical activity and healthy eating between Chinese adults with and without cardiovascular diseases (CVDs). This study is a cross-sectional component of Prospective Urban Rural Epidemiology (PURE)-China study, which recruited ~46,000 participants from 70 rural and 45 urban communities between 2005 and 2009. Participants were divided into disease (with CVDs) and control (without any diseases) groups. The adjusted rates were estimated for different strata by the generalized, linear mixed-effects model, including community as a random effect with additional adjustment for age, sex, education and income. Among 40,490 participants, <10% had all four healthy lifestyle behaviors (disease group versus control group: urban areas: 7.8% versus 8.1%; rural areas: 3.4% versus 3.2%). The rates of smoking cessation and quitting drinking were significantly higher in disease group for both urban and rural residents (P<0.001). In urban areas, higher rates were observed in all other three healthy lifestyle behaviors except physical activity in low-income regions (P<0.05). Similarly, the higher trends were observed for stopping smoking and drinking while opposite trends for healthy eating among rural residents from low-income regions (P<0.05). Our study showed that the prevalence of adopting all four behaviors was low among Chinese adults. Individuals with CVDs were more likely to follow healthy lifestyle behaviors, but it still indicated a large gap between the actual and ideal adoption of healthy lifestyle behaviors, which called for the promotion of population-wide strategies to modify lifestyle behaviors in addition to individual health-care intervention strategies.

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.

To understand how cognitive dysfunction contributes to social cognitive deficits in depression, we investigated the relationship between executive function and social cognitive performance in adolescents and young adults during current and remitted depression, compared to healthy controls. Social cognition and executive function were measured in 179 students (61 healthy controls and 118 patients with depression; M age = 20.60 years; SD age = 3.82 years). Hierarchical regression models were employed within each group (healthy controls, remitted depression, current depression) to examine the nature of associations between cognitive measures. Social cognitive and executive function did not significantly differ overall between depressed patients and healthy controls. There was no association between executive function and social cognitive function in healthy controls or in remitted patients. However, in patients with a current state of depression, lower cognitive flexibility was associated with lower performance in facial-affect recognition, theory-of-mind tasks and overall affect recognition. In this group, better planning abilities were associated with decreased performance in facial affect recognition and overall social cognitive performance. While we infer that less cognitive flexibility might lead to a more rigid interpretation of ambiguous social stimuli, we interpret the counterintuitive negative correlation of planning ability and social cognition as a compensatory mechanism.

To improve walking in persons with multiple sclerosis (MS), it is essential to understand the underlying mechanisms of walking. This study examined strategies in net joint power generated or absorbed by hip flexors, hip extensors, hip abductors, knee extensors, and plantar flexors in mildly disabled persons with MS and healthy controls at different walking speeds. Thirteen persons with MS and thirteen healthy controls participated and peak net joint power was calculated using 3D motion analysis. In general, no differences were found between speed-matched healthy controls and persons with MS, but the fastest walking speed was significantly higher in healthy controls (2.42 m/s vs. 1.70 m/s). The net joint power increased in hip flexors, hip extensors, hip abductors, knee extensors and plantar flexors in both groups, when walking speed increased. Significant correlations between changes in walking speed and changes in net joint power of plantar flexors, hip extensors and hip flexors existed in healthy controls and persons with MS, and in net knee extensor absorption power of persons with MS only. In contrast to previous studies, these findings suggest that mildly disabled persons with MS used similar kinetic strategies as healthy controls to increase walking speed.

The aim of this study was to establish how reliable a given tympanogram is in predicting the presence or absence of a middle ear effusion, and to provide new views for the diagnostic information of tympanometry. The use of tympanometric gradient in addition to static admittance is the focus of this study. The authors enrolled 146 female and 129 male patients. The participants were allocated into groups as follow: Group A1 consisted of 50 healthy children. Group A2 consisted of 86 children with otitis media with effusion. Group B1 consisted of 85 healthy adults. Group B2 consisted of 54 adults with otitis media with effusion. All diagnostic otoscopic examination and tympanometry were performed in both ears. The authors analyzed the distribution of tympanograms in patients with otitis media with effusion and healthy controls. When the right and left ear canal volume of either children or adults with otitis media with effusion compared with healthy controls, no statistically significant different was observed (P > 0.05). On the other hand, the statistically significant difference was detected for the values of compliance, pressure and gradient of either children or adults with otitis media with effusion compared with healthy controls (P < 0.05). The authors found the values range from 0.01 to 1.52 mL gradients (mean least value 0.15 mL) in adults and the values range from 0.01 to 0.93 mL gradients (mean least value 0.10 mL) in children in the presence of otitis media with effusion. The authors think that tympanometric gradient may be useful to detect the otitis media with effusion.

The aim of this work was to study the effects of cyclosporine (CsA), tacrolimus (FK-506), and rapamycin (RAPA) on bone mass, femoral microstructure, femoral biomechanical properties, and bone remodeling in healthy adult male rats. Forty-eight 5-month-old male Wistar rats were used. CsA (2 mg/kg/day), FK-506 (3 mg/kg/day), RAPA (1.25 mg/kg/day), or water (0.5 ml/rat/day, control group) were administered orally for 3 months. After sacrifice, mean values of immunosuppressants in blood were: CsA (670.4 ng/ml), FK-506 (19.2 ng/ml), and RAPA (4.8 ng/ml). Levels of biochemical parameters were normal in all groups. Femoral BMD was decreased in FK-506 and RAPA groups and lumbar BMD in FK-506 group. Trabecular volume fraction (BV/TV) decreased only in FK-506 group. RAPA and CsA affected femoral cortical structure, but FK-506 did not. FK-506 produced an increase in bone remodeling, and CsA a decrease. FK-506 group showed a decrease in biomechanical parameters relative to all groups. RAPA group showed a decrease in ultimate stress vs control group, and CsA group presented an increase in biomechanical parameters versus control group. We found that administration of both RAPA and FK-506 as monotherapy for healthy rats produced osteopenia. CsA treatment only produces slight damages in the cortical zone of the femur.

The aim of this study was to assess a suggested association between periodontitis and renal insufficiency by assaying kidney disease markers. VARIABLES USED TO DIAGNOSE PERIODONTITIS WERE: (i) probing pocket depth (PPD), (ii) attachment loss (AL), (iii) bleeding on probing (BOP), (iv) plaque index (PI) and (v) extent and severity index. Blood and urine were collected from 60 apparently healthy non-smokers (men and women), consisting of a test group of 30 subjects with periodontitis (age 46±6 yrs) and a control group of 30 healthy subjects (age 43±5 yrs). Kidney function markers (urea, creatinine, uric acid and albumin contents) were measured in the serum and urine. Also, the glomerular filtration rate was estimated from creatinine clearance, from the abbreviated Modification of Diet in Renal Disease formula and from the albumin : creatinine ratio in a 24-h sample of urine. It was found that the control group had a greater mean number of teeth than the test group and that the two groups also differed in PPD, AL, BOP and PI, all these variables being higher in the test group (P=0.006). For the extent and severity index of both PPD and AL, the test group had much higher medians of both extent and severity than the control group (P=0.001). With regard to kidney function, none of the markers revealed a significant difference between the control and test groups and all measured values fell within the reference intervals. It is proposed that severe periodontitis is not associated with any alteration in kidney function.

The aim of this study is to compare the white matter of multiple sclerosis (MS) patients with healthy controls and to monitor the response to the treatment with magnetic resonance spectroscopy (MRS).Fifteen healthy controls and 36 recently diagnosed MS patients never treated with interferon β were included in this study. In the patient group, MRS was performed before treatment, at 6th and 12th month after the initiation of treatment and once in control group. Patient group was divided into 3 interferon groups randomly. Physical examination findings were recorded as Expanded Disability Status Scale scores before treatment, at 6th and 12th month of interferon treatment.At the end of 1 year follow up, 26 of 36 patients completed the study. In patients' white matter lesions, N-acetylaspartate/creatine (NAA/Cr) ratios were lower than control group's white matters. NAA/Cr ratios were higher in control group's white matter than patient's normal appearing white matter but this difference was not statistically significant. There was no difference in choline/creatine (Cho/Cr) ratios between 2 groups. In follow-up period, NAA/Cr and Cho/Cr ratios obtained from patients' white matter lesions and normal appearing white matter did not change statistically.This study showed that in MS patients' white matters, especially in white matter lesions, neuron viability is reduced compared with healthy controls' normal white matter; and in the patients treated with interferon β NAA/Cr ratios remained stable. These stable levels of metabolite ratios in the patients who received interferon β therapy can be explained with either the shortness of the follow-up period post-treatment or may reflect a positive effect of the beta interferon therapy on the progress of MS.

Consanguineous unions occur in all populations around the world. Couples related as second cousins or closer have been observed with deleterious effect. Among the clinical effects of parental consanguinity, the incidence of offspring with congenital malformations (CM) increases approximately two-fold. A hospital database of neonates with CM was searched to select neonates with parental consanguinity and two control groups. One control group consisted of healthy neonates and the other control group consisted of neonates with CM but without parental consanguinity. Both control groups consisted of the first neonate of the same sex to be born after a consanguineous neonate with CM. Family, sociodemographic and anthropometric variables, as well as the severity of the malformations, were compared between the two groups with CM. Neonates with CM were grouped into five categories: Major multiple CM, minor multiple CM, isolated major CM, isolated minor CM, and specific diseases. The indigenous Mayan subpopulation was also analyzed. Among 1117 neonates with CM, parental consanguinity was found in 21. Parental consanguinity was also found in 8 neonates in the group of healthy controls (OR 2.4 [1.05-5.95]). The most common form of consanguinity was between second cousins and was more frequent in the Mayan subpopulation. Major multiple CM were more frequent among consanguineous than among nonconsanguineous couples. No association was found between the severity of CM and the degree of relationship. The prevalence of consanguinity found in neonates with CM and healthy controls (1.9 % and 0.8 %) was similar to that found in other Latin populations. A higher prevalence was found in the Mayan population. Mayor multiple CM were more frequent among the neonates of consanguineous than among nonconsanguineous couples.

Oxidative damage is involved in age-related inflammatory reactions. The anti-oxidative effects of hydrogen-rich water suppress oxidative damage, which may aid in inhibiting age-related inflammatory reactions. We investigated the effects of drinking hydrogen-rich water on aging periodontal tissues in healthy rats. Four-month-old male Fischer 344 rats (n = 12) were divided into two groups: the experimental group (hydrogen-rich water treatment) and the control group (distilled water treatment). The rats consumed hydrogen-rich water or distilled water until 16 months of age. The experimental group exhibited lower periodontal oxidative damage at 16 months of age than the control group. Although protein expression of interleukin-1β did not differ, gene expression of Nod-like receptor protein 3 inflammasomes was activated in periodontal tissues from the experimental group as compared with the control group. Drinking hydrogen-rich water is proposed to have anti-aging effects on periodontal oxidative damage, but not on inflammatory reactions in healthy rats. PMID:24985521

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

Although older people are particularly liable to sarcopenia, limited research is available on beta-hydroxy-beta-methylbutyrate (HMB) supplementation in this population, particularly in healthy subjects. In this parallel-group, randomized, controlled, open-label trial, we aimed to evaluate whether an oral supplement containing 1.5 g of calcium HMB for 8 weeks could improve physical performance and muscle strength parameters in a group of community-dwelling healthy older women. Eighty healthy women attending a twice-weekly mild fitness program were divided into two equal groups of 40, and 32 of the treated women and 33 control completed the study. We considered a change in the Short Physical Performance Battery (SPPB) score as the primary outcome and changes in the peak torque (PT) isometric and isokinetic strength of the lower limbs, 6-minute walking test (6MWT), handgrip strength and endurance as secondary outcomes. Body composition was assessed with dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computerized tomography (pQCT). The mean difference between the two groups on pre-post change were finally calculated (delta) for each outcome. After 8 weeks, there were no significant differences between the groups’ SPPB, handgrip strength or DXA parameters. The group treated with HMB scored significantly better than the control group for PT isokinetic flexion (delta = 1.56±1.56 Nm; p = 0.03) and extension (delta = 3.32±2.61 Nm; p = 0.03), PT isometric strength (delta = 9.74±3.90 Nm; p = 0.02), 6MWT (delta = 7.67±8.29 m; p = 0.04), handgrip endurance (delta = 21.41±16.28 s; p = 0.02), and muscle density assessed with pQCT. No serious adverse effects were reported in either group. In conclusion, a nutritional supplement containing 1.5 g of calcium HMB for 8 weeks in healthy elderly women had no significant effects on SPPB, but did significantly improve several muscle strength and physical performance parameters.

Young Liberians, particularly undereducated young adults, face substantial sexual and reproductive health (SRH) challenges, with low uptake of contraceptive methods, high rates of unintended pregnancy, and low levels of knowledge about HIV status. The purpose of this study was to assess the impact of a 6-day intensive group learning intervention combined with on-site SRH services (called HealthyActions) among out-of-school young adults, implemented through an existing alternative education program, on uptake of contraception and HIV testing and counseling (HTC). The intervention was implemented among young women and men ages 15-35 who were enrolled in alternative basic education learning sites in 5 counties of Liberia. We conducted a randomized evaluation to assess program impact. Baseline data were collected in January-March 2014, and endline data in June-July 2014. Key outcomes of condom use, contraceptive use, and HTC were estimated with difference-in-difference models using fixed effects. All analyses were conducted in Stata 13. We assessed outcomes for 1,157 learners at baseline and 1,052 learners at endline, across 29 treatment and 26 control sites. After adjusting for potential confounders, learners in the HealthyActions intervention group were 12% less likely to report never using a condom with a regular partner over the last month compared with the control group (P = .02). Female learners who received HealthyActions were 13% more likely to use any form of modern contraception compared with learners in control sites (P<.001), with the greatest increase in the use of contraceptive implants. Learners in HealthyActions sites were 45% more likely to have received HTC (P<.001). Providing intensive group learning in a supportive environment coupled with on-site health services improved SRH outcomes among participating learners. The focus of HealthyActions on participatory learning for low-literacy populations presents an adaptable solution for health programming across Liberia and the region. © Firestone et al.

Circadian rhythmicity of cysteinyl leukotrienes (LTs) and thromboxane (TX)-A(2) in healthy subjects and nocturnal asthmatic patients remains a subject of controversy. The aim of this study was to investigate the contribution of these mediators to the pathogenesis of nocturnal asthma. We measured peak expiratory flow rate, urinary concentration of LTE(4), 11-dehydro-TXB(2), and creatinine eight times every 3 h in three groups: healthy control subjects (n = 5, group A), nocturnal asthmatic patients (n = 9, group B), and nonnocturnal asthmatic subjects (n = 9, group C). To evaluate the reproducibility of the measurement of urinary LTE(4), we measured urinary LTE(4) in group A for 3 separate days. The urinary LTE(4) concentrations from 3 to 6 AM were significantly (p < 0.05) higher than from 3 to 6 PM in both group A and group B, but not in group C. The mean levels of LTE(4) in group B and group C were significantly higher (p < 0.05) than those in group A. In group B, another small peak was observed from 6 to 9 PM. No significant day-to-day variation was observed in group A. Urinary 11-dehydro-TXB(2) values from 3 to 6 AM were significantly (p < 0.001) higher than those levels from 3 to 6 PM in all groups, and the mean levels in group B and group C were significantly higher than those in group A (p < 0.05). Circadian rhythmicity of urinary LTE(4) with a morning peak was found in healthy control subjects and nocturnal asthmatic subjects, but not in nonnocturnal asthmatic patients. It was suggested that cysteinyl LTs rather than TXA(2) might contribute to the nocturnal worsening of asthma.

Objective To ascertain whether a parent education program based on Satter’s division of responsibility in feeding children (DOR) is effective in enhancing parent/child feeding interactions for children with an overweight/obese parent. The primary hypothesis was that the intervention would decrease parental pressure to eat. Methods Sixty-two families with a child aged 2–4 years with at least one overweight/obese parent were randomly allocated using a cluster design to either the DOR intervention or a control group. The control group focused on increasing family consumption of healthy foods and activity levels, and enhancing child sleep duration. The primary outcome was parent pressure on their child to eat. Results The DOR intervention was superior to the control group in reducing pressure to eat. Two moderators of pressure to eat were found: disinhibition of eating and hunger. DOR group parents irrespective of disinhibition levels lowered pressure to eat whereas control group parents with low disinhibition increased pressure to eat. There were similar findings for hunger. Gender moderated restrictive feeding with DOR parents lowering restriction more than the control group in girls only. Conclusion The DOR intervention was more effective in reducing parent pressure to eat and food restriction (in girls only) than the control group. PMID:22947882

Identification of functionally connected regions while at rest has been at the forefront of research focusing on understanding interactions between different brain regions. Studies have utilized a variety of approaches including seed based as well as data-driven approaches to identifying such networks. Most such techniques involve differentiating groups based on group mean measures. There has been little work focused on differences in spatial characteristics of resting fMRI data. We present a method to identify between group differences in the variability in the cluster characteristics of network regions within components estimated via independent vector analysis (IVA). IVA is a blind source separation approach shown to perform well in capturing individual subject variability within a group model. We evaluate performance of the approach using simulations and then apply to a relatively large schizophrenia data set (82 schizophrenia patients and 89 healthy controls). We postulate, that group differences in the intra-network distributional characteristics of resting state network voxel intensities might indirectly capture important distinctions between the brain function of healthy and clinical populations. Results demonstrate that specific areas of the brain, superior, and middle temporal gyrus that are involved in language and recognition of emotions, show greater component level variance in amplitude weights for schizophrenia patients than healthy controls. Statistically significant correlation between component level spatial variance and component volume was observed in 19 of the 27 non-artifactual components implying an evident relationship between the two parameters. Additionally, the greater spread in the distance of the cluster peak of a component from the centroid in schizophrenia patients compared to healthy controls was observed for seven components. These results indicate that there is hidden potential in exploring variance and possibly higher-order measures in resting state networks to better understand diseases such as schizophrenia. It furthers comprehension of how spatial characteristics can highlight previously unexplored differences between populations such as schizophrenia patients and healthy controls.

This study was conducted to investigate the deficits of organizational strategy and visual memory in obsessive-compulsive disorder (OCD). Thirty OCD patients and 30 healthy controls aged 20-35 years participated. The Maudsley Obsessive-Compulsive Inventory, Beck Anxiety Inventory, Wechsler Adult Intelligence Scale, and Rey-Osterrieth Complex Figure (ROCF) test were administered to participants. The authors scored ROCF performances using the Boston Qualitative Scoring System. The OCD patients showed poorer planning ability and higher fragmentation than did healthy controls when copying the ROCF, and they showed even poorer performances in the immediate and delayed recall conditions. The authors found that the Organization score in the copy condition mediated the difference between the OCD group and the healthy group in immediate recall. The direct effect of diagnosis (OCD or healthy) on the immediate recall condition of the ROCF was also significant. This study indicates that people with OCD have poor memory function and organizational deficits.

Congenital hypothyroidism (CH) is caused by thyroid dysgenesis and dyshormonogenesis. Evidence suggests the presence of genetic factors in both types of pathogenesis. We investigated whether an increased incidence of thyroid abnormalities could be shown by ultrasonography among first-degree relatives of children with CH. In this case-control study the presence of both developmental and non-developmental thyroid abnormalities was studied among first-degree relatives of CH patients and healthy children. Assessments included neck ultrasonography and thyroid function tests. The data obtained from parents, siblings and children were compared in the case and control groups. In the case group, 92 patients, 172 parents and 57 siblings, and in the control group, 82 healthy children, 160 parents and 39 siblings were studied. Thyroid developmental abnormalities were more prevalent among parents (3.5 vs. 0%, p = 0.03) and siblings (10.5 vs. 0, p = 0.01) of CH patients than the control group. Non-developmental abnormalities were not significantly different between the case and control groups (17 vs. 13%, p = 0.3). Thyroid developmental abnormalities were more prevalent among parents and siblings of CH patients than the control group, confirming the familial component of this entity. Copyright 2008 S.

To determine the relationship between mean arterial blood pressure (MAP) and blood viscosity in diabetic type 1 children and healthy controls to investigate whether MAP is independent of blood viscosity in healthy children, and vice versa. Children with diabetes type 1 treated by insulin injection were studied. Controls were healthy children of both sexes. MAP was calculated from systolic and diastolic pressure measurements. Blood viscosity was determined indirectly by measuring blood hemoglobin (Hb) content. The relationship between Hb, hematocrit (Hct) and blood viscosity was determined in a subgroup of controls and diabetics selected at random. 21 (10.6+/-2.5 years) type 1 diabetic children treated with insulin and 25 healthy controls age 9.6+/-1.7 years were studied. Hb was 13.8+/-0.8 g/dl in normal children vs. 14.3+/-0.9 g/dl in the diabetic group (p<0.05). MAP was 71.4+/-8.2 in the normal vs. 82.9+/-7.2 mmHg in the diabetic group (p<0.001). Glucose was 89.3+/-10.6 vs. 202.4+/-87.4 mg/dl respectively. Diabetics had a positive MAP/Hb correlation (p=0.007), while normals showed a non significant (p=0.2) negative correlation. The blood viscosity/Hb relationship was studied in a subgroup of 8 healthy controls and 8 diabetic type 1 children. There was no significant difference in Hb and Hct between groups. Diabetics showed a trend of increasing blood viscosity (+7%, p=0.15). Normal children compensate for the increase in vascular resistance due to increased blood viscosity (increased Hb and Hct) while diabetic children do not, probably due to endothelial dysfunction.

To investigate physical activity levels in youth with multiple sclerosis and monophasic acquired demyelinating syndromes ([mono-ADS], ie, children without relapsing disease) compared with healthy controls and to determine factors that contribute to engagement in physical activity. We hypothesized that greater physical activity goal setting and physical activity self-efficacy would be associated with greater levels of vigorous physical activity in youth with multiple sclerosis. A total of 68 consecutive patients (27 multiple sclerosis, 41 mono-ADS) and 37 healthy controls completed fatigue, depression, Physical Activity Self-Efficacy Scale, perceived disability, Exercise Goal-Setting scale, and physical activity questionnaires, and wore an accelerometer for 7 days. All patients had no ambulatory limitations (Expanded Disability Status Scale, scores all <4). Youth with multiple sclerosis engaged in fewer minutes per day of vigorous (P = .009) and moderate and vigorous physical activity (P = .048) than did patients with mono-ADS and healthy controls. A lower proportion of the group with multiple sclerosis (63%) reported participating in any strenuous physical activity than the mono-ADS (85%) and healthy control (89%) groups (P = .020). When we adjusted for age and sex, the Physical Activity Self-Efficacy Scale and Exercise Goal-Setting scale were associated positively with vigorous physical activity in the group with multiple sclerosis. Fatigue and depression did not predict physical activity or accelerometry metrics. Youth with multiple sclerosis participate in less physical activity than their counterparts with mono-ADS and healthy controls. Physical activity self-efficacy and exercise goal setting serve as potentially modifiable correlates of physical activity, and are measures suited to future interventions aimed to increase physical activity in youth with multiple sclerosis.

Encouraging adolescents to adopt healthy lifestyles can be challenging. The aim of the "Som la Pera" study was to engage adolescents by applying new strategies to increase both their fruit and vegetable consumption and their physical activity (PA) while reducing their sedentary behavior. In disadvantaged neighborhoods of Reus (Spain), two high schools were randomly assigned to the intervention (n = 170 adolescents 13- to 16-year-olds) and two were assigned to the control group (n = 223 adolescents 13- to 16-year-olds). The intervention, which lasted 12 months and spanned 2 academic years (2013-2015), used social marketing (SM) to improve healthy choices. The peer-led strategy involved 5 adolescents who designed and implemented 10 activities as challenges for their 165 school-aged peers. The control group received no intervention. To assess self-reported lifestyles in both groups, the Health Behavior in School-Aged Children Survey was used at baseline and end of study. After 12 months, intervention adolescents showed an increase of 28.9% in ≥1 fruit/day (p < 0.01) and of 18.5% in ≥6 hours/week of PA (p < 0.01) compared with controls. Additionally, intervention group males had an increase of 28.8% in ≥1 vegetable/day (p < 0.01) and of 15.6% in ≤2 hours/day of sedentary activity (p = 0.01) compared with controls. A school-based, peer-led, SM intervention developed by adolescents attending high schools in low-income neighborhoods effectively improved the healthy choices of their school-aged peers, leading to increased fruit consumption and PA in adolescents of both genders. Furthermore, adolescent males were more sensitive to improvements in healthy choices, showing increased vegetable consumption and decreased sedentary behavior.

Chronic fatigue syndrome (CFS) is a prevalent and disabling condition among adolescents. The pathophysiology is poorly understood, but low-grade systemic inflammation has been suggested as an important component. This study compared circulating levels of individual cytokines and parameters of cytokine networks in a large set of adolescent CFS patients and healthy controls, and explored associations between cytokines and symptoms in the CFS group. CFS patients (12-18years old) were recruited nation-wide to a single referral center as part of the NorCAPITAL project (ClinicalTrials ID: NCT01040429). A broad case definition of CFS was applied, requiring three months of unexplained, disabling chronic/relapsing fatigue of new onset, whereas no accompanying symptoms were necessary. Thus, the case definition was broader than the Fukuda-criteria of CFS. Healthy controls having comparable distribution of gender and age were recruited from local schools. Twenty-seven plasma cytokines, including interleukins, chemokines and growth factors were assayed using multiplex technology. The results were subjected to network analyses using the ARACNE algorithm. Symptoms were charted by a questionnaire, and patients were subgrouped according to the Fukuda-criteria. A total of 120 CFS patients and 68 healthy controls were included. CFS patients had higher scores for fatigue (p<0.001) and inflammatory symptoms (p<0.001) than healthy controls. All cytokine levels and cytokine network parameters were similar, and none of the differences were statistically different across the two groups, also when adjusting for adherence to the Fukuda criteria of CFS. Within the CFS group, there were no associations between aggregate cytokine network parameters and symptom scores. Adolescent CFS patients are burdened by symptoms that might suggest low-grade systemic inflammation, but plasma levels of individual cytokines as well as cytokine network measures were not different from healthy controls, and there were no associations between symptoms and cytokine expression in the CFS group. Low-grade systemic inflammation does not appear to be a central part of adolescent CFS pathophysiology. Copyright © 2014 Elsevier Inc. All rights reserved.

Previous studies have shown that pupillary response, a physiological measure of cognitive workload, reflects cognitive demand in healthy younger and older adults. However, the relationship between cognitive workload and cognitive demand in Parkinson’s disease (PD) remains unclear. The aim of this pilot study was to examine the pupillary response to cognitive demand in a letter-number sequencing (LNS) task between 16 non-demented individuals with PD (age, median (Q1–Q3): 68 (62–72); 10 males) and 10 control participants (age: 63 (59–67); 2 males), matched for age, education, and Montreal Cognitive Assessment (MOCA) scores. A mixed model analysis was employed to investigate cognitive workload changes as a result of incremental cognitive demand for both groups. As expected, no differences were found in cognitive scores on the LNS between groups. Cognitive workload, exemplified by greater pupil dilation, increased with incremental cognitive demand in both groups (p = 0.003). No significant between-group (p = 0.23) or interaction effects were found (p = 0.45). In addition, individuals who achieved to complete the task at higher letter-number (LN) load responded differently to increased cognitive demand compared with those who completed at lower LN load (p < 0.001), regardless of disease status. Overall, the findings indicated that pupillary response reflects incremental cognitive demand in non-demented people with PD and healthy controls. Further research is needed to investigate the pupillary response to incremental cognitive demand of PD patients with dementia compared to non-demented PD and healthy controls. Highlights -Pupillary response reflects cognitive demand in both non-demented people with PD and healthy controls-Although not significant due to insufficient power, non-demented individuals with PD had increased cognitive workload compared to the healthy controls throughout the testing-Pupillary response may be a valid measure of cognitive demand in non-demented individuals with PD-In future, pupillary response might be used to detect cognitive impairment in individuals with PD PMID:29692720

Impaired endothelial function is detectable in heart transplant (HTX) recipients and regarded as risk factor for coronary artery disease. We have studied whether endothelial function can be improved in HTX patients participating in a regular physical training program as demonstrated in patients with chronic heart failure, hypertension and coronary artery disease. Male HTX patients and healthy, age-matched controls were studied. Seven HTX patients (age: 60 +/- 6 yr; 6 +/- 2 yr of HTX) participated in an outpatient training program, six HTX patients (age: 63 +/- 8 yr; 7 +/- 1 yr of HTX) maintained a sedentary lifestyle without regular physical exercise since transplantation. A healthy control group comprised six subjects (age: 62 +/- 6 yr). Vascular function was assessed by flow-mediated dilation of the brachial artery (FMD). Systemic haemodynamic responses to intravenous infusion of the endothelium independent vasodilator sodium nitroprusside (SNP) and to NG-monomethyl-L-arginine (L-NMMA), an inhibitor of constitutive nitric oxide synthase, were also measured. Resting heart rate was significantly lower (p < 0.05) in healthy controls (66 +/- 13) than in the HTX training group (83 +/- 11) and in non-training HTX patients (91 +/- 9), baseline blood pressure also tended to be lower in healthy subjects and in the training HTX patients. FMD was significantly higher (p < 0.05) in the control group (8.4 +/- 2.2%) and in the training group (7.1 +/- 2.4%), compared with non-training HTX patients (1.4 +/- 0.8%). The response of systolic blood pressure (p = 0.08) and heart rate (p < 0.05) to L-NMMA was reduced in sedentary HTX patients compared with healthy controls and heart rate response to SNP was also impaired in sedentary HTX patients. Regular aerobic physical training restores vascular function in HTX patients, who are at considerable risk for developing vascular complications. This effect is demonstrable in conduit and systemic resistance arteries.

First, this study aimed to explore whether set-shifting is inefficient after full recovery of anorexia nervosa (recAN). Second, this study wanted to explore the relation of set-shifting to clinical and personality variables. A total of 100 recAN women were compared with 100 healthy women. Set-shifting was assessed with Berg's Card Sorting Test. Expert interviews yielded assessments for the inclusion/exclusion criteria, self-ratings for clinical and personality variables. Compared with the healthy control group, the recAN participants achieved fewer categories, showed more perseverations and spent less time for shifting set. Perfectionism is correlated with set-shifting but in converse directions in the two groups. Our study supports the findings of inefficiencies in set-shifting after full recovery from AN. Higher perfectionism in the recAN group is associated with better set-shifting ability, whereas higher perfectionism in the healthy control group is related to worse set-shifting ability.

  Anterior cruciate ligament (ACL) injury and ACL reconstruction (ACLR) result in persistent alterations in lower extremity movement patterns. The progression of lower extremity biomechanics from the time of injury has not been described.   To compare the 3-dimensional (3D) lower extremity kinematics and kinetics of walking among individuals with ACL deficiency (ACLD), individuals with ACLR, and healthy control participants from 3 to 64 months after ACLR.   We searched PubMed and Web of Science from 1970 through 2013.   We selected only articles that provided peak kinematic and kinetic values during walking in individuals with ACLD or ACLR and comparison with a healthy control group or the contralateral uninjured limb.   A total of 27 of 511 identified studies were included. Weighted means, pooled standard deviations, and 95% confidence intervals were calculated for the healthy control, ACLD, and ACLR groups at each reported time since surgery. The magnitude of between-groups (ACLR versus ACLD, control, or contralateral limb) differences at each time point was evaluated using Cohen d effect sizes and associated 95% confidence intervals. Peak knee-flexion angle (Cohen d = -0.41) and external knee-extensor moment (Cohen d = -0.68) were smaller in the ACLD than in the healthy control group. Peak knee-flexion angle (Cohen d range = -0.78 to -1.23) and external knee-extensor moment (Cohen d range = -1.39 to -2.16) were smaller in the ACLR group from 10 to 40 months after ACLR. Reductions in external knee-adduction moment (Cohen d range = -0.50 to -1.23) were present from 9 to 42 months after ACLR.   Reductions in peak knee-flexion angle, external knee-flexion moment, and external knee-adduction moment were present in the ACLD and ACLR groups. This movement profile during the loading phase of gait has been linked to knee-cartilage degeneration and may contribute to the development of osteoarthritis after ACLR.

To assess the impact of a nutrition education program for teachers in the nutritional status, food knowledge and food consumption of their pre basic and basic students, and in the controls. A nutrition education intervention was conducted in pre basic and basic teachers in a school year, with a pre-post evaluation of their students, compared with a control group. Subjects were 817 students (389 men and 428 women) from pre kindergarten to the second grade. The 465 students of the intervened group were distributed in two schools (Liceo 1 = 283; Liceo 2 = 182) and 352 in the control school. The nutrition intervention consisted in 9 interactive workshops for teachers with the utilization of Information and Communication Technologies (ICT). The pre post evaluation consisted in a nutritional status assessment, and a food and nutrition survey with questions related with food knowledge and food consumption, at the beginning and at the end of the school year. There were no significant differences in nutritional status between the beginning and the end of the intervention. In one of the experimental schools (Liceo 2) there was a significant decrease in obesity, in women and in the age-group 7-9 years. In the experimental group there was a significant improvement in food knowledge and a decrease in non-healthy food consumption. In the control group, consumption of non-healthy food was stable, with a decrease in fruits and vegetables consumption. As it was demonstrated in similar studies, a short interactive nutrition education intervention with utilization of ICT in pre basic and basic teachers can produce positive changes in nutritional status of their students, improving food knowledge and healthy food consumption and decreasing non-healthy food consumption, compared with the control group. However, a strategy to incorporate parents in school nutrition education programs is still a pending issue. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

Since mechanisms involved in the relationship between oxidative stress and breast cancer are still unclear, the aim of our present study was to evaluate oxidative/nitrative modifications of blood platelet proteins by measuring the level of biomarkers of oxidative/nitrative stress such as carbonyl groups, thiol groups and 3-nitrotyrosine in proteins in patients with benign breast diseases and in patients with invasive breast cancer, and compare with the control group. Levels of carbonyl groups and 3-nitrotyrosine residues in platelet proteins were measured by ELISA and a competition ELISA, respectively. The method with 5,5′-dithio-bis(2-nitro-benzoic acid) has been used to analyse free thiol groups in platelet proteins. Patients were hospitalized in the Department of Oncological Surgery, Medical University of Lodz, Poland. Exogenous antioxidants reduce oxidative stress, therefore we also investigated in a model system in vitro the effects of a polyphenol rich extract of Aronia melanocarpa (Rosaceae, final concentration of 50 µg/ml, 5 min, 37°C) on modified blood platelet proteins as well from patients with breast cancer and from the healthy group. We demonstrated in platelet proteins from patients with invasive breast cancer a higher level of carbonyl groups than in the control healthy group (p < 0.02). The level of 3-nitrotyrosine in platelet proteins from patients with invasive breast cancer was also significantly higher than in the healthy subject group (p < 0.001). In contrast, the amount of thiol groups in platelet proteins from patients was significantly lower (about < 50%) than in control blood platelets. In a model system in vitro we also observed that the extract from berries of A. melanocarpa (50 µg/ml, 5 min, 37°C) due to antioxidant action, significantly reduced the oxidative/nitrative stress (measured by thiol groups and 3-nitrotyrosine) in platelets, not only from the healthy group, but also from patients with benign breast diseases and in patients with invasive breast cancer.

This study addressed the question whether the composition of supposedly 'healthy' or 'unhealthy' dietary regimes has a calorie-independent short-term effect on biomarkers of metabolic stress and vascular risk in healthy individuals. Healthy male volunteers (age 29.5 ± 5.9 years, n = 39) were given a standardized baseline diet for two weeks before randomization into three groups of different dietary regimes: fast food, Mediterranean and German cooking style. Importantly, the amount of calories consumed per day was identical in all three groups. Blood samples were analyzed for biomarkers of cardiovascular risk and metabolic stress after two weeks of the baseline diet and after two weeks of the assigned dietary regime. No dietary intervention affected the metabolic or cardiovascular risk profile when compared in-between groups or compared to baseline. Subjects applied to the Mediterranean diet showed a statistically significant increase of uric acid compared to baseline and compared to the German diet group. Plasma concentrations of urea were significantly higher in both the fast food group and the Mediterranean group, when compared to baseline and compared to the German diet group. No significant differences were detected for the levels of vitamins, trace elements or metabolic stress markers (8-hydroxy-2-deoxyguanosine, malondialdehyde and methylglyoxal, a potent glycating agent). Established parameters of vascular risk (e.g. LDL-cholesterol, lipoprotein(a), homocysteine) were not significantly changed in-between groups or compared to baseline during the intervention period. The calorie-controlled dietary intervention caused neither protective nor harmful short-term effects regarding established biomarkers of vascular or metabolic risk. When avoiding the noxious effects of overfeeding, healthy individuals can possess the metabolic capacity to compensate for a potentially disadvantageous composition of a certain diet.

The objective of this study was to examine a novel profile: thiol-disulfide homeostasis in acute brucellosis. The study included 90 patients with acute brucellosis, and 27 healthy controls. Thiol-disulfide profile tests were analyzed by a recently developed method, and ceruloplasmin levels were determined. Native thiol levels were 256.72 ± 48.20 μmol/L in the acute brucellosis group and 461.13 ± 45.37 μmol/L in the healthy group, and total thiol levels were 298.58 ± 51.78 μmol/L in the acute brucellosis group and 504.83 ± 51.05 μmol/L in the healthy group (p < 0.001, for both). The disulfide/native thiol ratios and disulfide/total thiol ratios were significantly higher, and native thiol/total thiol ratios were significantly lower in patients with acute brucellosis than in the healthy controls (p < 0.001, for all ratios). There were either positive or negative relationships between ceruloplasmin levels and thiol-disulfide parameters. The thiol-disulfide homeostasis was impaired in acute brucellosis. The strong associations between thiol-disulfide parameters and a positive acute-phase reactant reflected the disruption of the balance between the antioxidant and oxidant systems. Since thiol groups act as anti-inflammatory mediators, the alteration in the thiol-disulfide homeostasis may be involved in brucellosis.

The associations between brain matter volume in the cerebral cortex and set shifting and attentional control as operationalized by the Wisconsin Card Sort Test (WCST) and Condition Three of the Delis-Kaplan version of the Color Word Interference Test (CWIT) were investigated in 15 healthy controls and 16 heterogeneously diagnosed psychiatric patients with self-control problems using voxel based morphometry. Both groups underwent standardized magnetic resonance imaging and neuropsychological assessment. WCST and CWIT variables, and a composite, were regressed across the whole brain. Although CWIT performance levels were the same in both groups, neuroanatomic correlates for the psychiatric participants invoked the left hemisphere language system, but the bilateral dorsal attention system in the healthy controls. On its own, no neuroanatomic correlates were observed for the WCST. But when part of a composite with CWIT, neuroanatomic correlates in the dorsal attention system emerged for the psychiatric participants. Psychometric combinations of manifest executive task variables may best represent higher level latent neuro-cognitive control systems. Factor analytic studies of neuropsychological test performances suggest the constructs being measured are the same across psychiatric and non-diagnosed participants, however, imaging modalities indicate the relevant neural architecture can vary by group. © 2013 Elsevier Ireland Ltd.

β-thalassemia major is a hereditary disease with inefficient erythropoiesis. Level of inflammatory cytokine is elevated in these patients. In this study, we investigate the effect of aryl hydrocarbon receptor (AhR) ligand, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), on the expression of inflammatory mediators in β-thalassemia major patient's lymphocytes. Peripheral blood mononuclear cells of patients and healthy participants was isolated and cultured in favor of lymphocytes increment. Based on the treatment, we divided the cell into four groups. The orders of group's treatments were no treatment, tumor necrosis factor-α (TNF-α) treatment, TNF-α and TCDD treatment, TCDD treatment in Group 1-4, respectively. After cell culture, we extracted the cells RNA and converted them to cDNA. Real-time polymerase chain reaction was performed to assessment relative expression of caspase-1, NLRP3, and AhR. We compared all patient groups with equal healthy (control) groups. Results showed that expression of caspase-1 in patients (Groups 1 and 2) was significantly lower than healthy individuals (P < 0.05). Although, no significant difference was found (Groups 1, 2, and control) in AhR gene expression (P > 0.05). Expression of AhR in other groups of patients (3 and 4) was significantly lower than control groups (P < 0.05). Expression of caspase-1 in Group 4 was significantly larger than the control group (P < 0.001). We show here that chronic inflammation decrease caspase-1 expression and exposure of human lymphocytes to TCDD promote caspase-1 expression. Furthermore, activation of AhR with TCDD decreases AhR expression in lymphocytes of β-thalassemia major disease.

To assess whether poor sleep quality experienced by regular shift workers and individuals with obstructive sleep apnea (OSA) affects neurobehavioral function similarly, or whether the different etiologies have distinct patterns of impairment. Thirty-seven shift workers (> 24 hours after their last shift), 36 untreated patients with OSA, and 39 healthy controls underwent assessment of sleepiness (Epworth Sleepiness Scale [ESS]), mood (Beck Depression Index, State Trait Anxiety Inventory [STAI], Profile of Mood States), vigilance (Psychomotor Vigilance Task [PVT], Oxford Sleep Resistance Test [OSLER], driving simulation), neurocognitive function (Logical Memory, Trails Making Task, Digit Span Task, Victoria Stroop Test) and polysomnography. Sleepiness (ESS score; median, interquartile range) did not differ between the OSA (10.5, 6.3-14) and shift work (7, 5-11.5) groups, but both had significantly elevated scores relative to the control group (5, 3-6). State anxiety (STAI-S) was the only mood variable that differed significantly between the OSA (35, 29-43) and shift work (30, 24-33.5) groups, however both demonstrated several mood deficits relative to the control group. The shift work and control groups performed similarly on neurobehavioral tasks (simulated driving, PVT, OSLER and neurocognitive tests), whereas the OSA group performed worse. On the PVT, lapses were significantly greater for the OSA group (3, 2-6) than both the shift work (2, 0-3.5) and control (1, 0-4) groups. Shift workers and patients with OSA had similar sleepiness and mood deficits relative to healthy individuals. However, only the patients with OSA showed deficits on vigilance and neurocognitive function relative to healthy individuals. These findings suggest that distinct causes of sleep disturbance likely result in different patterns of neurobehavioral dysfunction. © 2018 American Academy of Sleep Medicine.

This study is designed to test association of FOKI polymorphism in Vitamin D receptor (VDR) gene and its potential effect on expression of dopamine D1 receptor in schizophrenia and bipolar mood disorder as well as in healthy individuals. In this case-control study 196 patient with schizophrenia, 119 patients with bipolar mood disorder and 192 healthy individuals as the control group were recruited. All psychiatric disorders were diagnosed according to DSM IV criteria. Healthy control group denied any family history of such disorders. FOKI was genotyped by means of PCR-RFLP method. The mRNA was extracted from the peripheral blood mononuclear cells (PBMC) and the cDNA was synthesized. Frequency of ff genotype was more common in patients with bipolar disorders compared to the healthy control group (Odds ratio=1.84, 95% CI; 0.81 to 4.17) with increased relative risk (Relative risk=1.31, CI 95%; 0.86 to 1.99). There were significant differences between relative expressions of dopamine D1 receptor gene in various genotypes. Our results indicated that the ff genotype was associated with lower expression of dopamine D1 receptor gene. VDR as a nuclear receptor may contribute to bipolar disorders via modification of the expression of the neurotransmitters receptor such as dopamine.

Chemokine CX3CL1 (fractalkine) may be an important factor linking thyroid status and bone remodeling, through tetrac, a derivative of thyroxine. This study explores the relationship between serum fractalkine levels and parameters of thyroid status and bone in premenopausal women with Graves' disease (GD) in comparison to healthy controls. This cross-sectional study included three premenopausal female groups: active GD; cured GD, and healthy age-, gender-, and BMI-matched controls. Measurement of serum fractalkine levels (Quantikine ® ELISA), total amino-terminal peptide of procollagen type 1 (P1NP), CTx, thyroid hormones, BMD and trabecular bone score (TBS) were performed in all study subjects. Sixty women (21, 16, and 23 in active GD, cured GD, and healthy control groups, respectively) were included. Serum fractalkine levels were higher (p<0.05) in active and cured GD subjects compared to healthy controls (mean 0.7±0.14; 0.93±0.15, and 0.48±0.13 ng/ml, respectively). Lumbar spine BMD was lowest in the cured GD group in comparison to active GD and control group subjects (0.926±0.03; 1.016±0.03; 1.051±0.03 g/cm 2 ; p<0.05, respectively). TBS was lower (p<0.05) in both GD groups than controls being lowest in those with active GD (1.395±0.02; 1.402±0.02, 1.469±0.02, respectively). Serum fractalkine concentration was positively correlated with fT4, and negatively correlated with TBS values. GD in pre-menopausal females is associated with increased serum fractalkine concentration and decreased TBS. Fractalkine may be a currently unappreciated link between hyperthyroidism and bone; further research into this possibility is needed. © Georg Thieme Verlag KG Stuttgart · New York.

The inflammatory response to Mycobacterium tuberculosis bacilli influences tuberculosis (TB) progression. In this study, we aimed to identify the Phe206Leu polymorphism and serum L-selectin level in TB patients, compared to healthy individuals. Ninety patients with a diagnosis of TB and 90 healthy controls were selected in this study. The serum L-selectin level was determined, using ELISA. L-selectin polymorphism was also evaluated using PCR. For data analysis, SPSS was used at a significance level of 0.05. According to the findings, the mean±SD age of the participants was 57.5 ± 18.4 and 56.5 ± 17.5 years in the TB and healthy groups, respectively. The TB group showed a significantly higher serum L-selectin level (1721.1 ± 330.9) versus the healthy controls (1624 ± 279). The L-selectin Phe allele frequencies were higher than the Leu allele frequencies in the main population, whereas the patients and controls were not significantly different. Eight (0.04%) subjects had Leu/Leu genotypes, 84 (46.6%) carried Phe/Leu genotypes, and 88 (48.8%) had Phe/Phe genotypes. Our results showed that the groups were not significantly different regarding L-selectin genotypes. TB patients had a significantly higher serum L-selectin level, compared to the controls. Based on the findings, the incidence of TB and L-selectin polymorphism in the Phe206Leu gene had no significant association. © 2018 Wiley Periodicals, Inc.

The aim of this study was to investigate imaging statistical approaches for classifying 3D osteoarthritic morphological variations among 169 Temporomandibular Joint (TMJ) condyles. Cone beam Computed Tomography (CBCT) scans were acquired from 69 patients with long-term TMJ Osteoarthritis (OA) (39.1 ± 15.7 years), 15 patients at initial diagnosis of OA (44.9 ± 14.8 years) and 7 healthy controls (43 ± 12.4 years). 3D surface models of the condyles were constructed and Shape Correspondence was used to establish correspondent points on each model. The statistical framework included a multivariate analysis of covariance (MANCOVA) and Direction-Projection- Permutation (DiProPerm) for testing statistical significance of the differences between healthy control and the OA group determined by clinical and radiographic diagnoses. Unsupervised classification using hierarchical agglomerative clustering (HAC) was then conducted. Condylar morphology in OA and healthy subjects varied widely. Compared with healthy controls, OA average condyle was statistically significantly smaller in all dimensions except its anterior surface. Significant flattening of the lateral pole was noticed at initial diagnosis (p < 0.05). It was observed areas of 3.88 mm bone resorption at the superior surface and 3.10 mm bone apposition at the anterior aspect of the long-term OA average model. 1000 permutation statistics of DiProPerm supported a significant difference between the healthy control group and OA group (t = 6.7, empirical p-value = 0.001). Clinically meaningful unsupervised classification of TMJ condylar morphology determined a preliminary diagnostic index of 3D osteoarthritic changes, which may be the first step towards a more targeted diagnosis of this condition.

The aim of this study was to assess the degradation of collagen type I and proinflammatory cytokines in systemic and localized scleroderma compared with psoriasis and healthy controls. Total 99 individuals were examined - 24 with SSc, 22 with LSc, 39 patients with PsV and 14 healthy controls. U-PD and U-DPD were measured using a sensitive isocratic HPLC method. Serum levels of IL-6 and soluble IL-2R were assayed using commercial ELISA kits. In the SSc group U-PD and U-DPD levels (nmol/mmol creatinine) were increased compared with controls (P = 0.001) and with PsV (P = 0.006). IL-6 levels were increased compared with controls (P = 0.004) and with PsV (P = 0.002). IL-2R concentrations were insignificantly increased in comparison with controls and were lower than in PsV, but the difference was not significant. In the LSc group excretion of U-PD and U-DPD did not differ from controls, but was insignificantly decreased compared with PsV. IL-6 levels were increased compared with controls (P = 0.001) and also with PsV (P = 0.03). IL-2R concentrations were significantly increased in comparison with controls only (P = 0.03). In patients with SSc our data have shown the most intensive collagen degradation and simultaneously an active inflammation, as documented by IL-6, which reflects the pathological processes in the skin and visceral organs compared with PsV patients and healthy individuals. In the LSc group collagen degradation was similar to that in control groups, but a certain inflammatory activity was observed.

Negative mood and interference control in nonsuicidal self-injury.

Allen, Kenneth J D; Hooley, Jill M

People who engage in nonsuicidal self-injury (NSSI) often report high levels of impulsivity. However, results from behavioral tasks measuring impulsivity have been mixed: those with a history of NSSI generally perform comparably to healthy controls. Recent research suggests, however, that people who self-injure have specific deficits in response inhibition to negative emotional stimuli. Here, we extend this work by testing whether negative mood impairs interference control in NSSI. 33 participants reporting a history of NSSI (approximately half in the past year) and 31 age- and gender-matched healthy controls completed the multi-source interference task before and after a written negative mood induction designed to increase feelings of worthlessness, guilt, and shame. After the induction, the NSSI group reported increased negative mood but did not show worse interference control. In other words, increased negative mood did not correspond to increased behavioral impulsivity in participants reporting NSSI. Consistent with past research, the NSSI and healthy control groups showed equivalent task performance. This study adds to evidence that NSSI is not characterized by behavioral impulsivity, even in the context of negative mood. Copyright © 2016 Elsevier Inc. All rights reserved.

We designed a study to investigate the patterns of the steady-state visual evoked potential (SSVEP) and auditory steady-state response (ASSR) in adolescents with attention-deficit/hyperactivity disorder (ADHD) when performing a motor response inhibition task. Thirty 12- to 18-year-old adolescents with ADHD and 30 healthy control adolescents underwent an electroencephalogram (EEG) examination during steady-state stimuli when performing a stop-signal task. Then, we calculated the amplitude and phase of the steady-state responses in both visual and auditory modalities. Results showed that adolescents with ADHD had a significantly poorer performance in the stop-signal task during both visual and auditory stimuli. The SSVEP amplitude of the ADHD group was larger than that of the healthy control group in most regions of the brain, whereas the ASSR amplitude of the ADHD group was smaller than that of the healthy control group in some brain regions (e.g., right hemisphere). In conclusion, poorer task performance (especially inattention) and neurophysiological results in ADHD demonstrate a possible impairment in the interconnection of the association cortices in the parietal and temporal lobes and the prefrontal cortex. Also, the motor control problems in ADHD may arise from neural deficits in the frontoparietal and occipitoparietal systems and other brain structures such as cerebellum.

Objective: To find an association between human leukocyte antigen (HLA) class II DRB1, DRB3, DRB4, and DRB5 alleles frequencies in a sample of Iraqi patients with Guillain-Barré syndrome (GBS) and compare with a healthy control group. Methods: We performed a cross-sectional study consisting of 30 Iraqi Arab patients with GBS attending the Neurological Department in the Neuroscience Hospital, Baghdad, Iraq between September 2012 and June 2013. The control group comprised 42 apparently healthy volunteers. Human leukocyte antigen genotyping for HLA DRB1, DRB3, DRB4, and DRB5 was performed using the polymerase chain reaction-sequence-specific primers method. The allele frequencies were compared across both groups. Major histocompatibility complex (MHC)-class II HLA-DR genotyping and serotyping were performed by software analysis. Results: We found increased frequencies of HLA genotype DRB1*03:01 (p=0.0009), DRB1*07:01 (p=0.0015), and DRB4*01:01 (p<0.0001) in patients with GBS compared with healthy controls. The HLA DR6 was increased in the control group (p<0.0001). Conclusions: Our results suggest an association between HLA-DRB1*03:01, DRB1*07:01, DRB4*01:01, and HLA DR3, DR7 and a susceptibility to GBS. PMID:25274590

Saliva is a complex oral biologic fluid secreted by major and minor salivary glands. Saliva has immunological, enzymatic and antioxidant defense mechanisms. Infection with human immunodeficiency virus (HIV) is a life-threatening disease. The aim of this study was to evaluate salivary vitamin C and catalase levels in HIV-positive patients in comparison to a healthy control group. Forty-nine HIV-infected individuals and 49 healthy subjects were selected. Five mL of unstimulated saliva was collected in 5 minutes using a sterilized Falcon tube with Navazesh method. Catalase and vitamin C levels were assessed by spectrophotometric assay. Data were analyzed with STATA 12. Salivary catalase levels were 7.99±2.40 and 8.37±1.81 in the case and control groups, respectively. Catalase level was lower in the case group but the difference was not statistically significant (P=0.380). Salivary vitamin C levels in the case and control groups were 3.76±1.92 and 4.87±2.20, respectively (P=0.009). HIV can alter salivary antioxidant capacity as well as vitamin C and catalase levels. Saliva may reflect serum antioxidative changes in these patients. Therefore, further research is necessary on salivary and serum oxidants and the antioxidant changes.

This cross-sectional study aimed to measure the discrepancy between actual and perceived IQ in a sample of adolescents with CFS compared to healthy controls. We hypothesized that adolescents with CFS and their parent would have higher expectations of the adolescent's intellectual ability than healthy adolescents and their parent. The sample was 28 CFS patients and 29 healthy controls aged 11-19 years and the parent of each participant. IQ was assessed using the AH4 group test of general intelligence and a self-rating scale which measured perceived IQ. Parents' perceptions of their children's IQ were significantly higher for individuals with CFS than healthy controls. High expectations may need to be addressed within the context of treatment.

To compare sleep electroencephalographic patterns and psychological functioning of healthy adolescents running regularly in the mornings with those of control subjects. Although several studies have shown that regular moderate-to-vigorous exercise is related to favorable sleep and psychological functioning in adolescents, research on the effectiveness of short interventions is more limited. Fifty-one adolescents (mean age = 18.30 years; 27 female [53%]) took part in the study; they were randomly assigned either to a running or to a control group. The running group went running every morning for 30 minutes at moderate intensity during weekdays for 3 consecutive weeks. Sleep electroencephalographic patterns and psychological functioning were assessed in both groups before and after the 3-week period. All participants also kept a sleep log for 3 weeks. Objective sleep improved (slow-wave sleep increased; sleep onset latency decreased) in the running group compared with the control group. Subjective sleep quality, mood, and concentration during the day improved, whereas sleepiness during the day decreased. Thirty minutes of running in the morning during weekdays for 3 consecutive weeks impacted positively on sleep and psychological functioning in healthy adolescents compared with control subjects. Running is inexpensive and easy to implement during school schedules, and as both objective and subjective improvements were observed within 3 weeks, regular physical exercise should be promoted.

Exposure to bisphenol A (BPA) is known to be widespread and available data suggests that BPA can act as an endocrine disruptor. Diet is generally regarded as the dominant BPA exposure source, namely through leaching to food from packaging materials. The aim of this study was to evaluate the exposure of 110 Portuguese children (4-18 years old), divided in two groups: the regular diet group (n = 43) comprised healthy normal weight/underweight children with no dietary control; the healthy diet group (n = 67) comprised children diagnosed for obesity/overweight (without other known associated diseases) that were set on a healthy diet for weight control. First morning urine samples were collected and total urinary BPA was analyzed after enzymatic hydrolysis via on-line HPLC-MS/MS with isotope dilution quantification. Virtually, all the children were exposed to BPA, with 91% of the samples above the LOQ (limit of quantification) of 0.1 μg/L. The median (95th percentile) urinary BPA levels for non-normalized and creatinine-corrected values were 1.89 μg/L (16.0) and 1.92 μg/g creatinine (14.4), respectively. BPA levels in the regular diet group were higher than in the healthy diet group, but differences were not significant. Calculated daily BPA intakes, however, were significantly higher in children of the regular diet group than in children of healthy diet group. Median (95th percentile) daily intakes amounted to 41.6 (467) ng/kg body weight/day in the regular diet group, and 23.2 (197) ng/kg body weight/day in the healthy diet group. Multiple logistic regression analysis revealed that children in the healthy diet group had 33% lower intakes than children in the regular diet group (OR 0.67; 95% CI 0.51-0.89). For both groups, however, urinary BPA levels and daily BPA intakes were within the range reported for other children's populations and were well below health guidance values such as the European Food Safety Authority (EFSA) temporary tolerable daily intake (t-TDI) of 4 μg/kg body weight/day. In addition, lower daily BPA intakes were more likely linked with the inherent dietary approach rather than with high BMI or obesity.

Promotion of healthy eating and physical activity in early childhood is recommended as a global chronic disease prevention strategy. Centre-based childcare services represent a promising setting to provide children with opportunities to improve healthy eating and physical activity. Evidence to inform implementation of childcare obesity prevention guidelines into routine practice in childcare, however, is lacking. This study aims to assess the effectiveness of an intervention, delivered to childcare staff, aiming to increasing service implementation of healthy eating and physical activity-promoting policies and practices. A pragmatic parallel group randomised controlled trial will be undertaken with 165 childcare services in the Hunter New England region of New South Wales, Australia. Services will be randomised to receive either a 10-month evidence-based performance review intervention with other resources to support practice change, or to a waitlist control group. The primary trial outcome is the proportion of services implementing all of the following recommended healthy eating and physical activity promoting practices: written nutrition, physical activity and small screen recreation policies; providing information to families regarding healthy eating (including breastfeeding), physical activity and small screen time; providing twice weekly healthy eating learning experiences to children; providing water and only plain milk to children; providing fundamental movement skills activities for children every day; and limiting and using electronic screen time more for educational purposes and learning experiences. Effectiveness will be assessed using a telephone interview of practice implementation with childcare staff at baseline and 12 months following baseline. The study was approved by the Hunter New England Human Research Ethics Committee and the University of Newcastle Human Research Ethics Committee. Study findings will be disseminated widely through peer-reviewed publications and conference presentations. Australian New Zealand Clinical Trials Registry ACTRN12614000972628.

Characteristics of Labial Gland Mesenchymal Stem Cells of Healthy Individuals and Patients with Sjögren's Syndrome: A Preliminary Study.

PubMed

Wang, Shi-Qin; Wang, Yi-Xiang; Hua, Hong

2017-08-15

Sjögren's syndrome (SS) is a systemic autoimmune disease that is characterized by focal lymphocytic infiltration into exocrine organs such as salivary and lacrimal glands, resulting in dry mouth and eyes, and other systemic injuries. There is no curative clinical therapy for SS, and stem cell therapy has shown great potential in this area. The mesenchymal stem cells (MSCs) in the salivary glands of healthy individuals and in patients with SS have not been extensively studied. The aim of this study was to elucidate the characteristics of MSCs from the labial glands of healthy controls and of those from patients with SS to elucidate the related pathogenesis and to uncover potential avenues for novel clinical interventions. Labial glands from patients with SS and healthy subjects were obtained, and MSCs were isolated and cultured by using the tissue adherent method. The MSC characteristics of the cultured cells were confirmed by using morphology, proliferation, colony forming-unit (CFU) efficiency, and multipotentiality, including osteogenic, adipogenic, and salivary gland differentiation. The MSCs from the healthy controls and SS patients expressed characteristic MSC markers, including CD29, CD44, CD73, CD90, and CD105; they were negative for CD34, CD45, and CD106, and also negative for the salivary gland epithelium markers (CD49f and CD117). Labial gland MSCs from both groups were capable of osteogenic and adipogenic differentiation. The CFU efficiency and adipogenic differentiation potential of MSCs were significantly lower in the SS group compared with the healthy controls. Cells from both groups could also be induced into salivary gland-like cells. Real-time polymerase chain reaction and immunofluorescence staining showed that the gene and protein expression of AMY1, AQP5, and ZO-1 in cells from the SS group was lower than that in cells from the healthy group. Thus, MSCs from the labial glands in patients with SS could lack certain characteristics and functions, especially related to salivary secretion. These preliminary data provided insights that could lead to the development of novel therapeutic strategies for the treatment of SS.

Chronic pulmonary aspergillosis (CPA) complicates underlying lung disease, including treated tuberculosis. Measurement of Aspergillus-specific immunoglobulin G (IgG) is a key diagnostic step. Cutoffs have been proposed based on receiver operating characteristic (ROC) curve analyses comparing CPA cases to healthy controls, but performance in at-risk populations with underlying lung disease is unclear. We evaluated optimal cutoffs for the Siemens Immulite Aspergillus-specific IgG assay for CPA diagnosis in relation to large groups of healthy and diseased controls with treated pulmonary tuberculosis. Sera from 241 patients with CPA attending the UK National Aspergillosis Centre, 299 Ugandan blood donors (healthy controls), and 398 Ugandans with treated pulmonary tuberculosis (diseased controls) were tested. Radiological screening removed potential CPA cases from diseased controls (234 screened diseased controls). ROC curve analyses were performed and optimal cutoffs identified by Youden J statistic. CPA versus control ROC area under curve (AUC) results were: healthy controls 0.984 (95% confidence interval 0.972-0.997), diseased controls 0.972 (0.959-0.985), screened diseased controls 0.979 (0.967-0.992). Optimal cutoffs were: healthy controls 15 mg/l (94.6% sensitivity, 98% specificity), unscreened diseased controls 15 mg/l (94.6% sensitivity, 94.5% specificity), screened diseased controls 25 mg/l (92.9% sensitivity, 98.7% specificity). Results were similar in healthy and diseased controls. We advocate a cutoff of 20 mg/l as this is the midpoint of the range of optimal cutoffs. Cutoffs calculated in relation to healthy controls for other assays are likely to remain valid for use in a treated tuberculosis population.

The association between cardiovascular reactivity and major depressive disorder (MDD) remains unclear. This study aimed to examine this association via reactive heart rate variability (HRV) in a well-diagnosed first-episode MDD group and a control group. A total of 160 physically healthy, drug-naive patients presenting with their first-episode MDD and 50 healthy controls were recruited. All participants underwent a 5-min electrocardiography at rest and during a mental arithmetic task. Depression severity was assessed using the Beck Depression Inventory II (BDI). HRV measures that showed between-group differences at rest did not reached significance during mental stress. In contrast, HRV measures that revealed between-group differences during stress did not reach significance at rest. In response to mental stress, HRV measures did not significantly change in both group. However, LF and HF in response to stress were different between groups. Patients with MDD revealed an increasing trend in HF and a decreasing trend in LF; conversely, healthy controls had a decreasing trend in HF and an increasing trend in LF. BDI scores correlated with changes in heart rate in the control group. The fundamental change to reactive HRV in patients with first-episode MDD appears qualitative, not quantitative. A distinctly reverse trend in reactive HRV measures were evident between these two groups. Moreover, patients with MDD showed entirely distinct changes in reactive HRV from those in resting HRV. We suggest that in patients with MDD, autonomic system shifts to sympathetic dominance at rest but toward parasympathetic dominance in response to stress. Copyright © 2014 Elsevier Inc.

This study introduced a web-based educational intervention for Australian women with gestational diabetes mellitus (GDM). The aim was to improve knowledge on healthy diet and lifestyle in GDM. Evaluation of the intervention explored women's knowledge and understanding of GDM, healthy diet, healthy food, and healthy lifestyle, after using the web-based program compared to women receiving standard clinic-based GDM education. A total of 116 women, aged 18-45 years old, newly diagnosed with GDM, participated (Intervention (n) = 56 and control (n) = 60). Women were randomly allocated to the intervention or control groups and both groups attended a standard GDM education class. Group 1(Intervention) additionally used an online touch screen/computer program. All women completed a questionnaire following the computer program and/or the education class. All questions evaluating levels of knowledge had more than one correct answer and scores were graded from 0 to 1, with each correct component receiving a score, eg. 0.25 per each correct answer in a 4 answer question. Chi-square test was performed to compare the two groups regarding knowledge of GDM. Findings indicated that the majority of women in the intervention group reported correct answers for "types of carbohydrate foods" for pregnant women with GDM, compared to the control group (62.5 % vs 58.3 %, respectively). Most women in both groups had an excellent understanding of "fruits and vegetables" (98.2 % vs 98.3 %), and the majority of women in the intervention group understood that they should exercise daily for 30 min, compared to the control group (92.9 % vs 91.7 %). Both groups had a good understanding across all categories, however, the majority of women in the intervention group scored all correct answers (score = 1) in term of foetal effects (17.9 % vs 13.3 %, respectively), maternal predictors (5.4 % vs 5 %), care requirements (39.3 % vs 23.3 %), GDM perceptions (48.2 % vs 46.7 %) and GDM treatment (67.9 % vs 61.7 %), compared to women in the control group. The study suggested that both approaches, standard education and standard education plus web-based program, resulted in excellent knowledge scores, but not statistically significant difference between groups. Multiple and immediate access to the web-based education program at home may prove useful as a source of reference for women with GDM. Future study comparing results pre and post intervention is needed. ACTRN12615000697583 ; Date registered: 03/07/2015; Retrospectively registered.

This study analyzed the presence of DP symptoms in a sample of both psychiatric patients and normal subjects, addressing the issue of DP symptoms in adolescence. A total of 267 subjects (149 patients and 118 healthy controls) aged between 14 and 65 years, were assessed by means of CDS, the SCID-I and the K-SADS. The sample was then divided into two subsamples with a cut-off age of 21 years. As expected CDS score was significantly higher in the patient group compared to the healthy control group. As for the age issue, among patients no statistical difference was found comparing subjects over and under 21 years, whereas in the sample of healthy controls, subjects under 21 years reported CDS scores significantly higher. While in adults DP symptoms are frequently associated with mental disorders, in adolescents they could be considered as a quasi-physiological phenomenon. Copyright © 2015 Elsevier Inc.

2013-12-04

Children with congenital hypothyroidism (CH) who experience a neonatal thyroid hormone deficiency have reduced hippocampal volumes compared with healthy controls. Interestingly, evidence suggests that musical training can contribute to structural plasticity in a number of brain areas, including the hippocampus. Therefore, we investigated whether taking music lessons could ameliorate the volumetric reductions of the hippocampus in children with CH. Left and right hippocampal volumes were measured in four groups of children: children with CH with and without music lessons, and healthy controls with and without music lessons. We found that the volume of the right hippocampus was comparable between children with CH who had taken music lessons and the healthy controls. Children with CH who had not taken music lessons had reduced hippocampal volumes compared with the other three groups. These results suggest that music lessons may induce structural neuroplasticity in children with atypical hippocampal development because of early thyroid hormone deficiencies.

Disordered speech disrupts conversational entrainment: a study of acoustic-prosodic entrainment and communicative success in populations with communication challenges

2015-01-01

Conversational entrainment, a pervasive communication phenomenon in which dialogue partners adapt their behaviors to align more closely with one another, is considered essential for successful spoken interaction. While well-established in other disciplines, this phenomenon has received limited attention in the field of speech pathology and the study of communication breakdowns in clinical populations. The current study examined acoustic-prosodic entrainment, as well as a measure of communicative success, in three distinctly different dialogue groups: (i) healthy native vs. healthy native speakers (Control), (ii) healthy native vs. foreign-accented speakers (Accented), and (iii) healthy native vs. dysarthric speakers (Disordered). Dialogue group comparisons revealed significant differences in how the groups entrain on particular acoustic–prosodic features, including pitch, intensity, and jitter. Most notably, the Disordered dialogues were characterized by significantly less acoustic-prosodic entrainment than the Control dialogues. Further, a positive relationship between entrainment indices and communicative success was identified. These results suggest that the study of conversational entrainment in speech pathology will have essential implications for both scientific theory and clinical application in this domain.

To study glucose profiles of gestational diabetes (GDM) patients with 72 h of continuous glucose monitoring (CGM) either before (GDM1) or after (GDM2) dietary counseling, comparing them with nondiabetic (NDM) controls. We performed CGM on 22 GDM patients; 11 before and 11 after dietary counseling and compared them to 11 healthy controls. Several physiological and clinical characteristics of the glucose profiles were compared across the groups, including comparisons for pooled 24-h measures and hourly median values, summary measures representing glucose exposure (area under the median curves) and variability (amplitude, standard deviation, interquartile range), and time points related to meals. Most women (81.8%) in the GDM groups had fasting glucose <95mg/dL, suggesting mild GDM. Variability, glucose levels 1 and 2h after breakfast and dinner, peak values after dinner and glucose levels between breakfast and lunch, were all significantly higher in GDM1 than NDM (P<0.05 for all comparisons). The GDM2 results were similar to NDM in all aforementioned comparisons (P>0.05). Both GDM groups spent more time with glucose levels above 140mg/dL when compared with the NDM group. No differences among the groups were found for: pooled measurements and hourly comparisons, exposure, nocturnal, fasting, between lunch and dinner and before meals, as well as after lunch (P>0.05 for all). The main differences between the mild GDM1 group and healthy controls were related to glucose variability and excursions above 140mg/dL, while glucose exposure was similar. Glucose levels after breakfast and dinner also discerned the GDM1 group. Dietary counseling was able to keep glucose levels to those of healthy patients. © 2016 European Society of Endocrinology.

Studies have shown that people with multiple sclerosis (MS) report low levels of self-efficacy and self-esteem, high levels of anxiety and depression and reduced quality of life. The study aims to assess self-esteem, self-efficacy, mood and quality of life in young adults with MS and to compare them to a healthy control group. The age range for inclusion in the study was between 18 and 35years of age for both groups. Subjects with MS were recruited through the Italian MS Society. Healthy controls were recruited through social media and from a university undergraduate program. Subjects completed an anonymous online questionnaire combining various scales. Group differences on demographic data were assessed using parametric and non-parametric tests. Analyses of covariance (ANCOVA) were performed to evaluate differences between the two groups on scales of self-perception, mood and quality of life, adjusting for potentially confounding factors. Eighty-nine subjects with MS and 109 HC were included in the analysis. ANCOVA failed to demonstrate statistically significant differences between groups on self-esteem (F=0.11, p=0.743), self-efficacy (F=2.22, p=0.138), mood (anxiety F=0.03, p=0.855; depression F=0.06, p=0.812) and quality of life (F=0.08, p=0.772). This study demonstrated that young adults with MS and healthy controls have similar levels of self-esteem and self-efficacy and that they do not differ significantly on measures of mood and quality of life, as previously reported.

2015-01-01

Introduction The ability to recognize human biological motion is a fundamental aspect of social cognition that is impaired in people with schizophrenia. However, little is known about the neural substrates of impaired biological motion perception in schizophrenia. In the current study, we assessed event-related potentials (ERPs) to human and nonhuman movement in schizophrenia. Methods Twenty-four subjects with schizophrenia and 18 healthy controls completed a biological motion task while their electroencephalography (EEG) was simultaneously recorded. Subjects watched clips of point-light animations containing 100%, 85%, or 70% biological motion, and were asked to decide whether the clip resembled human or nonhuman movement. Three ERPs were examined: P1, N1, and the late positive potential (LPP). Results Behaviorally, schizophrenia subjects identified significantly fewer stimuli as human movement compared to healthy controls in the 100% and 85% conditions. At the neural level, P1 was reduced in the schizophrenia group but did not differ among conditions in either group. There were no group differences in N1 but both groups had the largest N1 in the 70% condition. There was a condition × group interaction for the LPP: Healthy controls had a larger LPP to 100% versus 85% and 70% biological motion; there was no difference among conditions in schizophrenia subjects. Conclusions Consistent with previous findings, schizophrenia subjects were impaired in their ability to recognize biological motion. The EEG results showed that biological motion did not influence the earliest stage of visual processing (P1). Although schizophrenia subjects showed the same pattern of N1 results relative to healthy controls, they were impaired at a later stage (LPP), reflecting a dysfunction in the identification of human form in biological versus nonbiological motion stimuli.

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.

The aim of the study was to assess the relationships between perceived parenting style, depressed mood, anxiety and self-esteem in adolescents with heart disease compared with healthy adolescents. Forty-five adolescents, aged 12-18 with congenital or acquired heart disease and 50 healthy age-matched adolescents answered perceived parental behaviour, self-esteem, depressed mood and anxiety questionnaires. The study group reported higher perceived acceptance and lower perceived parental control than healthy adolescents, but similar levels of depressed mood, anxiety and self-esteem. Fischer's r-to-z transformation and regression analyses showed different associations between perceived parenting style and depressed mood, anxiety and self esteem. In the study group, higher perceived parental acceptance was associated with lower depressed mood and higher self-esteem, whereas these associations were not significant in the control group. In the control, but not the study group, higher perceived parental control was associated with lower depressed mood and lower anxiety. Parenting style proved to exert a differential effect on adolescents with and without heart disease. For the former, perceived parental acceptance had a more substantial effect on psychological well-being than perceived parental control. Professionals caring for these adolescents should be aware of the special importance of parenting style on the well-being of adolescents with heart disease, and address this issue in the clinical setting with the patients and their parents.

Gingival epithelium plays a key role in the protection of oral tissues from microbial challenge, especially during the periodontal disease. This study was aimed to evaluate levels of mRNA transcripts of different forms of transglutaminase in the human gingival tissues from patients with chronic periodontitis and relative controls. This study included 22 patients with chronic periodontitis (CP) and 22 healthy controls. For each patient, the values of probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were recorded. Gene expression of transglutaminase 1, transglutaminase 2, transglutaminase 3, and metalloprotease 2 was evaluated by real-time PCR, while that of Factor XIIIA and metalloprotease 9 by RT-PCR. The values of all the clinical parameters were significantly higher in the CP group than in the healthy control group (P < 0.05). In the CP group, the mRNA expression of transglutaminase 1 and transglutaminase 3 was significantly decreased in comparison with healthy control group. A slight nonsignificant changes of transglutaminase 2 gene expression were observed in samples from CP patients in comparison with controls. These observations suggest that transglutaminase gene expression may be modified in response to chronic injury in the damaged gingival and emphasizes the key role of these enzymes in gingival remodelling/healing and adaptive processes. © 2013 John Wiley & Sons A/S.

This study evaluated the effectiveness of a healthy body image program. In total, 421 adolescent boys completed a five-session intervention program or a wait list control group. There were no differences between the intervention and the control group at post-intervention or any of the follow-up times. Boys in the intervention group who were one standard deviation above the mean on body dissatisfaction at baseline, demonstrated a reduction in negative affect in the intervention group at post-test and 6 months follow-up. Prevention programs need to target boys who are at risk of adopting health risk behaviors, rather than being universally applied. Copyright 2009 Elsevier Ltd. All rights reserved.

To determine the existence of mucosal dysbiosis in siblings of patients with Crohn's disease (CD) using 454 pyrosequencing and to comprehensively characterise and determine the influence of genotypical and phenotypical factors, on that dysbiosis. Siblings of patients with CD have elevated risk of developing CD and display aspects of disease phenotype, including faecal dysbiosis. Whether the mucosal microbiota is disrupted in these at-risk individuals is unknown. Rectal biopsy DNA was extracted from 21 patients with quiescent CD, 17 of their healthy siblings and 19 unrelated healthy controls. Mucosal microbiota was analysed by 16S rRNA gene pyrosequencing and were classified into core and rare species. Genotypical risk was determined using Illumina Immuno BeadChip, faecal calprotectin by ELISA and blood T-cell phenotype by flow cytometry. Core microbiota of both patients with CD and healthy siblings was significantly less diverse than controls. Metacommunity profiling (Bray-Curtis (SBC) index) showed the sibling core microbial composition to be more similar to CD (SBC=0.70) than to healthy controls, whereas the sibling rare microbiota was more similar to healthy controls (SBC=0.42). Faecalibacterium prausnitzii contributed most to core metacommunity dissimilarity both between siblings and controls, and between patients and controls. Phenotype/genotype markers of CD risk significantly influenced microbiota variation between and within groups, of which genotype had the largest effect. Individuals with elevated CD-risk display mucosal dysbiosis characterised by reduced diversity of core microbiota and lower abundance of F. prausnitzii. This dysbiosis in healthy people at risk of CD implicates microbiological processes in CD pathogenesis. Published by the BMJ Publishing Group Limited.

Personality has an important role in understanding both fibromyalgia syndrome (FMS) and major depressive disorder (MDD). This study considers the question that specific personality features may characterize depressed FMS patients. To this end, 125 individuals were included in the study: 40 of them diagnosed with FMS+ MDD, 40 with MDD only and 45 healthy controls. Individual Beck Depression Inventory (BDI) and Personality Belief Questionnaire-Short Form (PBQ-SF) scores were compared between the three groups. The mean scores for each personality domain of the PBQ-SF were the highest in the MDD group and the lowest mean scores appeared in the control group. Dependent personality and obsessive-compulsive personality scores were higher in the MDD group (t = 2.510, P = 0.014 and t = 2.240, P = 0.028, respectively) in comparison with the FM+ MDD group. However, this difference disappeared when PBQ-SF scores were controlled for depression severity. Although some common personality features are evident in FMS patients, it seems that the differences identified are primarily related to depression symptom severity.

Platelets can modulate lymphocytes' role in the pathophysiology of thyroid autoimmune diseases. The present study was performed to clarify the status of platelet-lymphocyte subpopulations aggregation in circulating blood in patients with Graves' disease (GD). One hundred and fifty patients with GD (GD group) and 45 hyperthyroid patients with toxic multinodular goiter (TMG group) were recruited in the study. Control group consisted 150 healthy subjects. Immunophenotyping of lymphocytes was performed by flow cytometry. Detection of lymphocyte-platelet aggregates (LPAs) was done using light microscope after Ficoll-gradient centrifugation. The group of GD patients exhibited reduced CD8 lymphocyte and higher CD19 cell counts compared with TMG group and healthy controls. A greater number of activated CD3, HLA-DR+ lymphocytes were observed in GD than in TMG group and control group. GD group was characterized by lower blood platelet count (232 ± 89 × 10 cells/µL) than TMG group (251 ± 97 × 10 cells/µL; P < 0.05) and control group (262 ± 95 × 10 cells/µL; P < 0.05). In GD group, more platelet-bound lymphocytes (332 ± 91 /µL) were found than that in TMG group (116 ± 67/µL, P < 0.005) and control group (104 ± 58 /µL; P < 0.001). GD is associated with higher levels of activated lymphocytes and lymphocyte-platelet aggregates.

Breast cancer (BC) and/or its treatments may affect sexual functioning based on physiological and psychosocial mechanisms. The aim of this study was to prospectively investigate sexual adjustment of BC patients during a follow-up period of one year after mastectomy (ME) or breast conserving therapy (BCT). In this prospective controlled study, women with BC and an age-matched control group of healthy women completed the Beck Depression Inventory Scale, World Health Organization 5 Well-being scale, Body Image Scale, EORTC QLQ questionnaire, Dyadic Adjustment Scale, Short Sexual Functioning Scale and Specific Sexual Problems Questionnaire to assess various aspects of sexual and psychosocial functioning before surgery, six months and one year after surgical treatment. In total, 149 women with BC and 149 age-matched healthy controls completed the survey. Compared to the situation before surgery, significantly more BCT women reported problems with sexual arousal six months after surgery and significantly more women of the ME group reported problems with sexual desire, arousal and the ability to achieve an orgasm six months and one year after surgery. While in comparison with healthy controls, no significant differences in sexual functioning were found after BCT surgery, significantly more women who underwent ME reported problems with sexual desire, arousal, the ability to achieve an orgasm and intensity of the orgasm. Although little differences were seen in sexual functioning in the BCT group during prospective analyses and in comparison with healthy controls, analyses revealed that women who underwent a ME were at risk for post-operative sexual dysfunctions.

Depression is a clinically relevant dimension, associated with both positive and negative symptoms, in patients with schizophrenia. However, in siblings it is unknown whether depression is associated with subclinical positive and negative symptoms. Method Depressive symptoms and their association with positive and negative symptoms were examined in 813 healthy siblings of patients with a non-affective psychotic disorder, 822 patients and 527 healthy controls. Depressive episodes meeting DSM-IV-TR criteria (lifetime) and depressed mood (lifetime) were assessed with the Comprehensive Assessment of Symptoms and History (CASH) in all three groups. In the patient group, the severity of positive and negative psychosis symptoms was assessed with the CASH. In the siblings and healthy controls, the severity of subclinical psychosis symptoms was assessed with the Community Assessment of Psychic Experiences (CAPE). Patients reported more lifetime depressed mood and more depressive episodes than both siblings and controls. Siblings had a higher chance of meeting lifetime depressive episodes than the controls; no significant differences in depressed mood were found between siblings and controls. In all three groups the number and duration of depressive symptoms were associated with (sub)clinical negative symptoms. In the patients and siblings the number of depressive symptoms was furthermore associated with (sub)clinical positive symptoms. Finally, lifetime depressed mood showed familial clustering but this clustering was absent for lifetime depressive episodes. These findings suggest that a co-occurring genetic vulnerability for both depressive and psychotic symptomatology exists on a clinical and a subclinical level.

Whether the unaffected function of the hand of patients presenting with nerve injury is affected remains inconclusive. We aimed to evaluate whether there are differences in finger tapping following central or peripheral nerve injury compared with the unaffected hand and the ipsilateral hand of a healthy subject. Thirty right brain stroke patients with hemiplegia, 30 left arm peripheral nerve injury cases, and 60 healthy people were selected. We tested finger tapping of the right hands, and each subject performed the test twice. Finger tapping following peripheral nerve injury as compared with the unaffected hand and the dominant hand of a healthy person was markedly higher than was found for central nerve injury (P < 0.05). Finger tapping of the male peripheral group's unaffected hand and the control group's dominant hand was significantly higher than the central group (P < 0.001). However, finger tapping of the female control group's dominant hand was significantly higher than the central group's unaffected hand (P < 0.01, P = 0.002), the peripheral group's unaffected hand (P < 0.05, P = 0.034). The unaffected function of the hand of patients with central and peripheral nerve injury was different as compared with the ipsilateral hand of healthy individuals. The rehabilitation therapist should intensify the practice of normal upper limb fine activities and coordination of the patient.

The purpose of the study was to analyse and compare KT-1000 knee laxity as examined by a left-hand- and a right-hand-dominant physiotherapist in a group of patients with an anterior cruciate ligament (ACL) injury and a group of patients, 2 years after ACL reconstruction. The other aim was to measure and analyse knee laxity in a group of persons without any known knee problems. A cross-sectional examination of two groups of patients pre-operatively and post-operatively after ACL reconstruction and examination of healthy controls on two different occasions was performed. Fifty-three patients who were scheduled for ACL reconstruction and 39 patients who attended a 2-year follow-up examination were included in the study. In the ACL-deficient group, 32 patients had a right-sided ACL injury and 21 patients a left-sided ACL injury. The corresponding figures in the post-operative group were 21 patients with a right-sided ACL injury and 18 patients with a left-sided ACL injury. Twenty-eight healthy persons without any known knee problems served as controls. One left-hand- and one right-hand-dominant experienced physiotherapist performed all the examinations. To be able to evaluate the intra and inter-reliability of the examiners the controls were examined at two occasions. The left-hand-dominant physiotherapist measured significantly higher absolute laxity values in the left knee, both injured and non-injured ones, compared with the right-hand-dominant physiotherapist. This was found irrespectively of whether the patients belonged to the ACL deficient or the post-operative group. In the healthy control group, the right-hand-dominant physiotherapist measured significantly higher knee-laxity values in the right knee compared with the left-hand-dominant physiotherapist. Correspondingly, the left-hand-dominant physiotherapist measured significantly higher knee laxity values in the left knee. We conclude that KT-1000 arthrometer laxity measurements can be affected by the hand dominance of the examiner. This might affect the reliability of KT-1000 arthrometer measurements. Level of evidence is II.

The boundary between bipolar disorder (BD) and borderline personality disorder is a controversial one. Despite the importance of the topic, few studies have directly compared these patient groups. The aim of the study was to compare the executive functioning profile of BD and BPD patients. Executive functioning (sustained attention, problem-solving, planning, strategy formation, cognitive flexibility and working memory) was assessed in BD (n=30) and BPD outpatients (n=32) using a computerized assessment battery (Cambridge Neuropsychological Test Automated Battery, CANTAB). The groups were compared to one another as well as to healthy controls. BD patients showed deficits in strategy formation and in planning (indicated by longer execution time in the ToL task) in comparison to BPD patients and healthy controls. BPD patients showed deficits in planning (short deliberation time in the ToL task) in comparison to BD patients and in comparison to healthy controls. In comparison to healthy controls, BPD patients displayed deficits in problem-solving. Differences in executive dysfunction between BD and BPD patients suggest that this cognitive dimension may be relevant for the clarification of the boundary between the disorders. Copyright © 2015.

We investigated the differences in brain fMRI signal complexity in patients with schizophrenia while performing the Cyberball social exclusion task, using measures of Sample entropy and Hurst exponent (H). 13 patients meeting diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM IV) criteria for schizophrenia and 16 healthy controls underwent fMRI scanning at 1.5 T. The fMRI data of both groups of participants were pre-processed, the entropy characterized and the Hurst exponent extracted. Whole brain entropy and H maps of the groups were generated and analysed. The results after adjusting for age and sex differences together show that patients with schizophrenia exhibited higher complexity than healthy controls, at mean whole brain and regional levels. Also, both Sample entropy and Hurst exponent agree that patients with schizophrenia have more complex fMRI signals than healthy controls. These results suggest that schizophrenia is associated with more complex signal patterns when compared to healthy controls, supporting the increase in complexity hypothesis, where system complexity increases with age or disease, and also consistent with the notion that schizophrenia is characterised by a dysregulation of the nonlinear dynamics of underlying neuronal systems.

Pseudoexfoliation (PEX) syndrome (PES) is characterized by the widespread deposition of abnormal extracellular fibrillary material on many ocular and extraocular tissues. The objective of this study was to evaluate the association among PES, PEX glaucoma (PEG), and mean platelet volume (MPV). Forty patients with PES (mean age 62.6 ± 7.8 years), 31 with PEG (mean age 65.9 ± 6.6 years), and 37 healthy individuals (control group) (mean age 64.0 ± 7.1 years) were included in the study. The MPV of the 3 groups were compared. Age and sex distribution were similar among groups (p>0.05). Mean MPV in PES, PEG, and control groups were 9.59 ± 0.94 fl, 9.53 ± 0.80 fl, and 7.7 ± 0.67 fl, respectively. In the PEX group, MPV values were significantly higher than in the control group (p<0.05). However, there was no difference between the PES and PEG groups (p>0.05). The MPV values in both groups with PEX were higher than those in the healthy group.

We hypothesized that administration of the superoxide dismutase (SOD) mimetic Tempol (4-hydroxy-2, 2, 6, 6-tetramethylpiperidine 1-oxyl) may reverse diabetes induced ED(erectile dysfunction). To test this hypothesis, ROS related genes (SOD1, SOD2, GPx1, CAT, NOS2, NOS3), erectile functional studies, and immunohistochemical analysis were performed in diabetic rats treated with or without Tempol. Thirty Sprague-Dawley (3–4 months old) rats were divided into 3 groups (n=10 each), 20 with diabetes (diabetic control and Tempol treatment) and 10 healthy controls. Twelve weeks after induction of diabetes by streptozotocin and Tempol treatment, all groups underwent in vivo cavernous nerve stimulation. Rat crura were harvested and expression of antioxidative defense enzymes examined by semi-quantitative RT-PCR. To confirm the RT-PCR results, we performed immunohistochemistry (IHC) for catalase (CAT) and iNOS (NOS2). Nitration of tyrosine groups in proteins was also examined by IHC. Mean intracavernous pressure in the diabetic group was significantly lower than in healthy controls (p<0.001) and was reversed by Tempol treatment (p<0.0108). NOS2 protein expression was significantly increased in diabetic animals compared to healthy controls and Tempol restored NOS2 protein level. Nitrotyrosine was also higher in diabetic animals and though Tempol treatment decreased its formation, it remained higher than that found in healthy controls. This study suggests that Tempol treatment increased erectile function through modulating oxidative stress related genes in diabetic rats. This is the first report about the relationship between diabetes induced erectile dysfunction and oxidative stress, and anti-oxidative therapy using the superoxide dismutase mimetic, Tempol to restore erectile function.

Hemophilia is a common hereditary hemorrhagic disorder, however little is known about the oral microflora of hemophilic patients. The aim of this study was to quantify the Candida and identify its species in non-stimulated saliva of hemophilic patients, and consider its relationship with clinical factors influencing Candida carriage. This study comprised evaluation of 86 hemophilic patients of the Hematology Center/UNICAMP and 43 healthy subjects as controls. All patients were submitted to anamnesis, intraoral examination and unstimulated saliva collection. Candida counts and species identification were performed in salivary samples. Candida was present in 64% of the hemophilic patients and in 44% of the healthy controls. C. albicans represented 65% and 68% of the isolated species, in hemophiliacs and control group respectively, and C. tropicalis was the second most common species in both groups. These results indicate that hemophilic patients carry Candida more frequently and in higher counts than healthy controls, independently of oral clinical parameter considered, as viral infections, complete dentures, transfusions of hemoderivatives, and salivary flow.

To develop an ecologically valid measure of executive functioning (i.e. Planning and Organization, Executive Memory, Initiation, Cognitive Shifting, Impulsivity, Sustained and Directed Attention, Error Detection, Error Correction and Time Management) during a functional chocolate brownie cooking task. In Study 1, the inter-rater reliability of a novel behavioural observation assessment method was assessed with 10 people with traumatic brain injury (TBI). In Study 2, 27 people with TBI and 16 healthy controls completed the functional task along with other measures of executive functioning to assess validity. Intraclass correlation coefficients for six of the nine aspects of executive functioning ranged from .54 to 1.00. Percentage agreements for the remaining aspects ranged from 70% to 90%. Significant and non-significant, moderate, correlations were found between the functional cooking task and standard neuropsychological measures. The healthy control group performed better than the TBI group in six areas (d = 0.56 to 1.23). In this initial trial of a novel assessment method, adequate inter-rater reliability was found. The measure was associated with standard neuropsychological measures, and our healthy control group performed better than the TBI group. The measure appears to be an ecologically valid measure of executive functioning.

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

- Previous evidence trying to assess the risk of celiac disease among dyspeptic patients has been inconclusive, showing in some cases notorious discrepancies. - To determine the prevalence of celiac disease in patients with dyspepsia compared to healthy controls without dyspepsia. - Adult patients under evaluation for dyspepsia were invited to participate. These patients were offered an upper gastrointestinal endoscopy with duodenal biopsies. On the other hand, asymptomatic adult volunteers who performed a preventive visit to their primary care physician were invited to participate and agreed to undertake an upper gastrointestinal endoscopy with duodenal biopsies as well. Those patients with histologic signs of villous atrophy were furtherly evaluated and serological tests were performed in order to determine celiac disease diagnosis. Celiac disease prevalence was compared between groups. - Overall, 320 patients with dyspepsia and 320 healthy controls were recruited. There were no significant differences in terms of gender or age between groups. Celiac disease diagnosis was made in 1.25% (4/320) of patients in the dyspepsia group versus 0.62% (2/320) in the control group. - Patients with dyspepsia who underwent routine duodenal biopsies did not show an increased risk for celiac disease when compared to healthy individuals.

The purpose of this study was to verify whether male patients with psychosis have greater neurocognitive impairment than female patients at illness onset. Participants with a first episode of psychosis (74 women/86 men) and healthy controls (62 women/97 men) were assessed with an extensive neuropsychological test battery. Women in the clinical group were older at illness onset and had achieved higher formal education than men. This trend was the same for the control group. The patient group presented with lower premorbid IQ compared to healthy controls, and performed below for most neuropsychological tests. Women scored higher than men on a test of verbal memory, whereas men scored higher than women on a test of reaction time, visual memory, and a planning task. There were no group-by-sex interactions for any of the neuropsychological tests. The present study shows that at the onset of psychosis there are no differences between males and females in neuropsychological performance. The differential pattern of cognitive performance observed is similar to that in healthy males and females. Furthermore, females with a late onset of psychosis may represent a subgroup with specific visuospatial and problem solving impairments. © 2013.

Cognitive control under contingencies in anxious and depressed adolescents: an antisaccade task.

Emotion-related perturbations in cognitive control characterize adult mood and anxiety disorders. Fewer data are available to confirm such deficits in youth. Studies of cognitive control and error processing can provide an ideal template to examine these perturbations. Antisaccade paradigms are particularly well suited for this endeavor because they provide exquisite behavioral measures of modulation of response errors. A new monetary reward antisaccade task was used with 28 healthy, 11 anxious, and 12 depressed adolescents. Performance accuracy, saccade latency, and peak velocity of incorrect responses were analyzed. Performance accuracy across all groups was improved by incentives (obtain reward, avoid punishment). However, modulation of saccade errors by incentives differed by groups. In incentive trials relative to neutral trials, inhibitory efficiency (saccade latency) was enhanced in healthy, unaffected in depressed, and diminished in anxious adolescents. Modulation of errant actions (saccade peak velocity) was improved in the healthy group and unchanged in both the anxious and depressed groups. These findings provide grounds for testing hypotheses related to the impact of motivation deficits and emotional interference on directed action in adolescents with mood and anxiety disorders. Furthermore, neural mechanisms can now be examined by using this task paired with functional neuroimaging.

AIM To investigate the place of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in the diagnosis of and prognosis for neovascular age-related macular degeneration (AMD). METHODS One hundred AMD patients and 100 healthy controls were included in the study. Blood samples were obtained from the venous blood, which is used for routine analysis, and these samples were subjected to complete blood count. NLR was defined as the neutrophil count divided by the number of lymphocytes, and PLR was defined as the platelet count divided by the number of lymphocytes. RESULTS No statistically significant difference was observed between the two groups under consideration in terms of demographic features (P>0.05). The average NLR in the patient group was found to be significantly higher than that in the healthy control group (P<0.05). The average PLR was significantly higher in the patient group as compared to the control group (P<0.05). As best corrected visual acuity (BCVA) increased, both NLR and PLR decreased (significant negative correlations at 49.8% and 63.0%, respectively), whereas as central macular thickness (CMT) increased, both NLR and PLR increased (significant positive correlations at 59.3% and 70.0%, respectively). CONCLUSION NLR and PLR levels are higher among neovascular AMD patients as compared to healthy control group. NLR and PLR levels were found to be inversely proportional to BCVA and directly proportional to CMT. PMID:28546933

Burn scars are frequently accompanied with sensory deficits often remaining present months or even years after injury. Clinimetric properties of assessment tools remain understudied within burn literature. Tactile sense of touch can be examined with the touch pressure threshold (TPT) method using the Semmes Weinstein monofilament test (SWMT). There is in recent research no consensus on the exact measurement procedure when using the SWMT. The aim of this paper was to determine the interrater and intrarater reliability of TPT within burn scars and healthy controls using the 'ascending descending' measurement procedure. We used the newly developed guidelines for reporting reliability and agreement studies (GRRAS) as a basis to report this reliability study. In total 36 individuals were tested; a healthy control group and a scar group. The interrater reliability was excellent in the scar group (ICC=0.908/SEM=0.21) and fair to good in the control group (ICC=0.731/SEM=0.12). In the scar group intrarater ICC value was excellent (ICC=0.822/SEM=0.33). Within the control group also an excellent intrarater reliability (ICC=0.807/SEM=0.27) was found. In conclusion this study shows that the SWMT with the 'ascending descending' measurement procedure is a feasible and reliable objective measure to evaluate TPT in (older) upper extremities burn scars as well as in healthy skin.

Dexmedetomidine is useful during mapping of epileptic foci as it facilitates electrocorticography unlike most other anesthetic agents. Patients with seizure disorders taking enzyme-inducing anticonvulsants appear to be resistant to its sedative effects. The objective of the study was to compare the pharmacokinetic and pharmacodynamic profile of dexmedetomidine in healthy volunteers with volunteers with seizure disorders receiving enzyme-inducing anticonvulsant medications. Dexmedetomidine was administered using a step-wise, computer-controlled infusion to healthy volunteers (n = 8) and volunteers with seizure disorders (n = 8) taking phenytoin or carbamazapine. Sedation and dexmedetomidine plasma levels were assessed at baseline, during the infusion steps, and after discontinuation of the infusion. Sedation was assessed by using the Observer's Assessment of Alertness/Sedation Scale, Ramsay Sedation Scale, and Visual Analog Scale and processed electroencephalography (entropy) monitoring. Pharmacokinetic analysis was performed on both groups, and differences between groups were determined using the standard two-stage approach. A two-compartment model was fit to dexmedetomidine concentration-time data. Dexmedetomidine plasma clearance was 43% higher in the seizure group compared with the control group (42.7 vs. 29.9 l/h; P = 0.007). In contrast, distributional clearance and the volume of distribution of the central and peripheral compartments were similar between the groups. No difference in sedation was detected between the two groups during a controlled range of target plasma concentrations. This study demonstrates that subjects with seizure disorders taking enzyme-inducing anticonvulsant medications have an increased plasma clearance of dexmedetomidine as compared with healthy control subjects.

To measure the foveal avascular zone (FAZ) area after internal limiting membrane (ILM) peeling and to determine the factors significantly correlated with the FAZ area. This was a retrospective, observational, and cross-sectional study. The affected and normal fellow eyes of 102 patients with unilateral macular diseases and 169 healthy subjects were studied. The patients underwent successful vitrectomy with internal limiting membrane peeling for an epiretinal membrane (n = 56) or a macular hole (n = 46). The superficial FAZ area and average foveal (within 1 mm) thickness were measured. The main outcome measures were the en face FAZ area measured in the optical coherence tomography angiographic images. The FAZ area in the epiretinal membrane group (0.148 ± 0.094 mm) and in the macular hole group (0.255 ± 0.111 mm) were significantly smaller than that in the healthy control group (0.358 ± 0.118 mm; all, P < 0.0001). Multiple regression analysis showed that a thicker fovea was significantly correlated with a smaller FAZ area in the epiretinal membrane group (r = -0.799, P < 0.0001), macular hole group (r = -0.473, P = 0.0042), and control group (r = -0.612, P < 0.0001). The FAZ area after internal limiting membrane peeling was smaller than that of the controls. A smaller FAZ area was correlated with a thicker fovea both in internal limiting membrane-peeled eyes and normal eyes.

This study examines explicit memory bias for emotional information in children and adolescents with major depressive disorder (MDD). Participants were a convenient sample of 28 children and adolescents of mothers with MDD, 28 children and adolescents with MDD, and 29 healthy controls. Their age range was 11-17 years old. The groups were matched for gender ratio, mean age, and the years of educational level. They were assessed by the Recall Task. Emotional stimuli consisted of three sets of words namely sad, happy, and neutral words. Children and adolescents of mothers with MDD similar to children and adolescents with MDD recalled more sadness stimuli in comparison with the controls. In other words, they showed an explicit memory bias towards sad stimuli. Also, healthy children significantly recalled more happy words than the other two groups. There was no significant difference among the three groups for the recall of neutral stimuli. Current findings support that there is a recall memory bias for emotional information in children with MDD. These children more than healthy children recall sad words. Moreover, healthy children recall happy words more than children with MDD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The bacterial community structure of buccal mucosa in patients with oral lichen planus was evaluated and compared with healthy control. Buccal scraping samples have been taken on 43 oral lichen planus patients (21 erosive and 22 non-erosive) and 21 mucosal healthy volunteers. The V3 hypervariable 16S rDNA region was amplified and sequenced by high-throughput 454 pyrosequencing. 94.26% of the total buccal bacteria were classified into 15 abundant genera. Eight of these abundant genera could be detected in all cases, namely Streptococcus, Prevotella, Haemophilu, Neisseria, Fusobacterium, Leptotrichia, Veillonella and Actinomyces. Four abundant bacteria showed significantly different prevalence at the genus level: Streptococcus was more abundant (P < 0.01) in healthy control group, while Fusobacterium (P < 0.01), Leptotrichia (P < 0.001) and Lautropia (P < 0.001) showed higher abundance in OLP group. Few differences can be found between erosive and non-erosive OLP. In general, 19 'core' OTUs at three levels were defined to be OLP specific, comparing with healthy control group. These results suggest that OLP is associated with dysbiosis of the oral microbiome. Further studies should be taken to elucidate the inner relationship between these observed changes and OLP development. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Context:  Neuromuscular and mechanical deficiencies are commonly studied in participants with chronic ankle instability (CAI). Few investigators have attempted to comprehensively consider sensorimotor and mechanical differences among people with CAI, copers who did not present with prolonged dysfunctions after an initial ankle sprain, and a healthy control group. Objective:  To determine if differences exist in spinal reflex excitability and ankle laxity among participants with CAI, copers, and healthy controls. Design:  Case-control study. Setting:  Research laboratory. Patients or Other Participants:  Thirty-seven participants with CAI, 30 participants categorized as copers, and 26 healthy control participants. Main Outcome Measure(s):  We assessed spinal reflex excitability of the soleus using the Hoffmann reflex protocol. Participants' ankle laxity was measured with an instrumented ankle arthrometer. The maximum Hoffmann reflex : maximal muscle response ratio was calculated. Ankle laxity was measured as the total displacement in the anterior-posterior directions (mm) and total rotation in the inversion and eversion directions (°). Results:  Spinal reflex excitability was diminished in participants with CAI compared with copers and control participants (P = .01). No differences were observed among any of the groups for ankle laxity. Conclusion:  Changes in the spinal reflex excitability of the soleus that likely affect ankle stability were seen only in the CAI group, yet no mechanical differences were noted across the groups. These findings support the importance of finding effective ways to increase spinal reflex excitability for the purpose of treating neural excitability dysfunction in patients with CAI. PMID:27065189

To study the impact of administration of dydrogesterone in early pregnancy on pregnancy outcome and its correlation with Th1 and Th2 cytokine levels. Double-blind, randomized, placebo-controlled study. A medical college and its associated hospital. Women with either: [1] a history of idiopathic recurrent pregnancy loss (RPL), in either a dydrogesterone group or a placebo group, or [2] no history of miscarriage. Dydrogesterone 20 mg/day from confirmation of pregnancy to 20 weeks of gestation. Occurrence of another pregnancy loss and concentrations of T-helper (Th)1 (interferon-γ and tumor necrosis factor-α) and Th2 (interleukin (IL)-4 and IL-10) cytokines in serum at recruitment (4-8 weeks of gestation) and at abortion or 20 weeks of gestation, using commercially available ELISA kits. Occurrence of another abortion after 3 consecutive abortions was significantly higher (29 of 173; 16.76%) in women with RPL compared with healthy pregnant controls (6 of 174; 3.45%). Risk of occurrence of miscarriage after 3 abortions was 2.4 times higher in the placebo group vs. the treatment group (risk ratio=2.4, 95% CI=1.3-5.9). Mean gestational age at delivery (excluding those aborted before 20 weeks of gestation) increased significantly in the dydrogesterone group (38.01±1.96 weeks) compared with the placebo group (37.23±2.41 weeks). Baby weight was significantly lower in the placebo group (2421.4±321.6 g) compared with the healthy pregnant controls (2545.3±554.3 g). At recruitment, serum IL-4 and tumor necrosis factor-α levels were significantly lower in the RPL group compared with the healthy pregnant controls. However, serum interferon-γ level was significantly higher in the RPL group (8.87±0.72 pg/mL) compared with the healthy pregnant controls (8.08±1.27 pg/mL). The present study supports the use of dydrogesterone in women with recurrent abortions to improve pregnancy outcome, such as a reduction in abortions and improved gestational age and baby weight at delivery. However, these outcomes were not modulated by Th1 and Th2 cytokine production. CTRI/2010/091/000373. Copyright © 2014 American Society for Reproductive Medicine. Published by Elsevier Inc.

To study the retinal vessel oxygen saturation alterations in patients with autoimmune retinopathy (AIR) and patients with autoimmune retinopathy associated with retinitis pigmentosa (AIR-RP) in comparison with healthy controls and patients with isolated retinitis pigmentosa (RP). Prospective, cross-sectional, and non-interventional study. Retinal vessel oximetry (RO) was performed on a total of 139 eyes: six eyes suffering from AIR and four eyes with AIR-RP were compared to 59 healthy control eyes and to 70 eyes with RP. A computer-based program of the retinal vessel analyser unit (IMEDOS Systems UG, Jena, Germany) was used to evaluate retinal vessel oxygen saturation. The mean oxygen saturation in the first and second branch retinal arterioles (A-SO 2 ) and venules (V-SO 2 ) were measured and their difference (A-V SO 2 ) was calculated. In addition, we measured the diameter of the retinal arterioles (D-A) and venules (D-V). Oxygen metabolism is altered in patients with isolated AIR and AIR-RP. Both, AIR and AIR-RP groups, differed from healthy controls showing significantly higher V-SO 2 values and significantly lower A-V SO 2 values (p < 0.025). In addition, the AIR-RP group could be differentiated from eyes suffering from isolated RP by means of significantly higher V-SO 2 values. Comparing retinal vessel diameters, both, the AIR and AIR-RP groups, presented with significant arterial (p = 0.05) and venular (p < 0.03) vessel attenuation than the healthy control group. Based on our results, in analogy to patients suffering from RP, oxygen metabolism seems to be altered in AIR patients.

An anthropometric study was undertaken to assess head proportions of patients with X-linked hypophosphatemia (XLH). Fourteen morphometric parameters of the head were measured and 10 cephalic indices calculated in 82 affected persons (57 females and 25 males) from 55 unrelated families with XLH, and compared with the results obtained in the group of their healthy relatives (37 females and 33 males), as well as with general population control values. Normalized values (SD, z-score) were analyzed statistically. The group of healthy relatives, both males and females, differed significantly from Polish population control values in most of the normalized variables measured, making population control values useless as a control group for the analyzed XLH group. Intrafamilial values of cephalic parameters in healthy relatives of the XLH patients were finally applied for statistical analysis. Generally patients with XLH showed highly statistically significant increase in head length (males 0.95 +/- 1.07 vs. -0.37 +/- 1.02, females 0.57 +/- 1.59 vs. -0.06 +/- 1.15), significant decrease in occipital breadth (males -0.56 +/- 1.27 vs. 0.70 +/- 1.28, females -0.59 +/- 1.7 vs. 0.13 +/- 1.1) and several milder anomalies of craniofacial proportions. Mean cephalic index was significantly lower in XLH patients when compared with the healthy relatives (males -0.909 vs. 0.278 P < 0.0001, females -0.705 vs. 0.381 P = 0.007). The cephalic changes were found both in XLH children and XLH adults and were more pronounced in affected males than in females. There were no differences between offspring born by hypophosphatemic and normophosphatemic mothers. Copyright 2003 Wiley-Liss, Inc.

Implicit associations in social anxiety disorder: the effects of comorbid depression.

2014-08-01

Implicit associations of the self to concepts like "calm" have been shown to be weaker in persons with social anxiety than in non-anxious healthy controls. However, other implicit self associations, such as those to acceptance or rejection, have been less studied in social anxiety, and none of this work has been conducted with clinical samples. Furthermore, the importance of depression in these relationships has not been well investigated. We addressed these issues by administering two Implicit Association Tests (IATs; Greenwald, McGhee, & Schwartz, 1998), one examining the implicit association of self/other to anxiety/calmness and the other examining the association of self/other to rejection/acceptance, to individuals with generalized social anxiety disorder (SAD, n=85), individuals with generalized SAD and a current or past diagnosis of major depressive disorder or current dysthymic disorder (n=47), and non-anxious, non-depressed healthy controls (n=44). The SAD and SAD-depression groups showed weaker implicit self-calmness associations than healthy controls, with the comorbid group showing the weakest self-calmness associations. The SAD-depression group showed the weakest implicit self-acceptance associations; no difference was found between non-depressed individuals with SAD and healthy controls. Post hoc analyses revealed that differences appeared to be driven by those with current depression. The SAD-only and SAD-depression groups did not differ in self-reported (explicit) social anxiety. The implications of these findings for the understanding of SAD-depression comorbidity and for the treatment of SAD are considered. Copyright © 2014 Elsevier Ltd. All rights reserved.

Glycosylated haemoglobin (HbA1c) level can consequently be interpreted as an average of the blood glucose present over the past 3-4 months. Periodontitis is associated with glycemic control in patients with diabetes. The purpose of this study was to determine the level of HbA1c in healthy and periodontitis patients who were previously not diagnosed with diabetes mellitus. A total of 40 patients were selected for study and divided into two groups. Group 1 included patients with a healthy periodontium, and Group 2 included patients suffering from chronic periodontitis. Finger stick blood was collected by special collection unit (A1CNOW+® Bayer Health Care, Tarrytown New York, USA), for estimating level of HbA1c. Both groups showed similar HbA1c levels clinically with slight increase in levels in the test group, but was statistically significant (test--5.66 ± 0.35%, control--5.17 ± 0.3% P = 0.003). Indians are at a high-risk of developing periodontitis and diabetes. These data suggest a possible link between periodontitis and glycemic control in nondiabetic individuals, periodontal disease may be a potential contributor to the development of type 2 diabetes.

Objective To evaluate the effect of short-term hormone replacement therapy with tibolone 2.5 mg daily on endothelial function of healthy postmenopausal women, using flow-mediated dilation (FMD) of the brachial artery. Methods We performed a randomized, double-blinded, placebo-controlled study. A total of 100 healthy postmenopausal women were randomly allocated to receive tibolone (n = 50) or placebo (n = 50) for 28 days. Measurement of the FMD of the brachial artery was performed before and after the use of tibolone and placebo. Results A total of 31 women completed the study in the tibolone group, and 32 women completed the study in the control group. The results of the FMD measurements obtained from the women in the two groups before treatment were similar (0.018 and 0.091, for tibolone and placebo, p = 0.57). The values of the FMD in women who used tibolone and placebo, before and after the treatment, were similar in both groups. The numbers of women who presented an increase in the values of the FMD in both groups were also similar. Conclusion Our results demonstrate that the administration of 2.5 mg tibolone to healthy postmenopausal women for 28 days does not promote endothelial-dependent vasodilation, measured by FMD of the brachial artery.

Using the Theory of Planned Behavior (I. Ajzen, 1985, 1991) and referent group (student) norms and identification (D. J. Terry & M. A. Hogg, 1996), the authors longitudinally predicted healthy eating intentions and behavior in a sample of 137 university students. Specifically, attitudes, subjective norms, and perceived control predicted intentions at Time 1, which predicted self-reported behavior at Time 2. There was also a link between intentions and observed behavior at Time 2. Beyond the planned behavior variables, referent group norms for university students' eating behavior interacted with participants' identification as students to predict healthy eating intentions. The authors discussed implications for researcher's conceptualization of normative influence and for interventions into this group's eating behavior.

Heart Rate Variability (HRV) indicates how heart rate changes in response to inner and external stimuli. HRV is linked to health status and it is an indirect marker of the autonomic nervous system (ANS) function. To investigate the influence of osteopathic manipulative treatment (OMT) on cardiac autonomic modulation in healthy subjects, compared with sham therapy and control group. Sixty-six healthy subjects, both male and female, were included in the present 3-armed randomized placebo controlled within subject cross-over single blinded study. Participants were asymptomatic adults (26.7 ± 8.4 y, 51% male, BMI 18.5 ± 4.8), both smokers and non-smokers and not on medications. At enrollment subjects were randomized in three groups: A, B, C. Standardized structural evaluation followed by a patient need-based osteopathic treatment was performed in the first session of group A and in the second session of group B. Standardized evaluation followed by a protocoled sham treatment was provided in the second session of group A and in the first session of group B. No intervention was performed in the two sessions of group C, acting as a time-control. The trial was registered on clinicaltrials.gov identifier: NCT01908920. HRV was calculated from electrocardiography before, during and after the intervention, for a total amount time of 25 min and considering frequency domain as well as linear and non-linear methods as outcome measures. OMT engendered a statistically significant increase of parasympathetic activity, as shown by High Frequency power (p < 0.001), expressed in normalized and absolute unit, and possibly decrease of sympathetic activity, as revealed by Low Frequency power (p < 0.01); results also showed a reduction of Low Frequency/High Frequency ratio (p < 0.001) and Detrended fluctuation scaling exponent (p < 0.05). Findings suggested that OMT can influence ANS activity increasing parasympathetic function and decreasing sympathetic activity, compared to sham therapy and control group.

Schizophrenia patients are often impaired in their memory for emotional events compared with healthy subjects. Investigations of the neural correlates of emotional memory in schizophrenia patients are scarce in the literature. The present study aimed to compare cerebral activations in schizophrenia patients and healthy controls during memory retrieval of emotional images that varied in both valence and arousal. In a study with functional magnetic resonance imaging, 37 schizophrenia patients were compared with 37 healthy participants while performing a yes/no recognition paradigm with positive, negative (differing in arousal intensity) and neutral images. Schizophrenia patients performed worse than healthy controls in all experimental conditions. They showed less cerebral activation in limbic and prefrontal regions than controls during retrieval of negatively valenced stimuli, but had a similar pattern of brain activation compared with controls during retrieval of positively valenced stimuli (particularly in the high arousal condition) in the cerebellum, temporal lobe and prefrontal cortex. Both groups demonstrated increased brain activations in the high relative to low arousing conditions. Our results suggest atypical brain function during retrieval of negative pictures, but intact functional circuitry of positive affect during episodic memory retrieval in schizophrenia patients. The arousal data revealed that schizophrenia patients closely resemble the control group at both the behavioral and neurofunctional level. 2011 Elsevier Ireland Ltd. All rights reserved.

Evaluating the diagnostic utility of applying a machine learning algorithm to diffusion tensor MRI measures in individuals with major depressive disorder.

Using MRI to diagnose mental disorders has been a long-term goal. Despite this, the vast majority of prior neuroimaging work has been descriptive rather than predictive. The current study applies support vector machine (SVM) learning to MRI measures of brain white matter to classify adults with Major Depressive Disorder (MDD) and healthy controls. In a precisely matched group of individuals with MDD (n =25) and healthy controls (n =25), SVM learning accurately (74%) classified patients and controls across a brain map of white matter fractional anisotropy values (FA). The study revealed three main findings: 1) SVM applied to DTI derived FA maps can accurately classify MDD vs. healthy controls; 2) prediction is strongest when only right hemisphere white matter is examined; and 3) removing FA values from a region identified by univariate contrast as significantly different between MDD and healthy controls does not change the SVM accuracy. These results indicate that SVM learning applied to neuroimaging data can classify the presence versus absence of MDD and that predictive information is distributed across brain networks rather than being highly localized. Finally, MDD group differences revealed through typical univariate contrasts do not necessarily reveal patterns that provide accurate predictive information. Copyright © 2017 Elsevier Ireland Ltd.

The aim of this study is to measure GABA levels of perisylvian cortices in schizophrenia and bipolar disorder patients, using proton magnetic resonance spectroscopy (1H-MRS). Patients with schizophrenia (n=25), bipolar I disorder (BD-I; n=28) and bipolar II disorder (BD-II; n=20) were compared with healthy controls (n=30). 1H-MRS data was acquired using a Siemens 3 Tesla whole body scanner to quantify right and left perisylvian structures’ (including superior temporal lobes) GABA levels. Right perisylvian GABA values differed significantly between groups [χ2=9.62, df: 3, p = 0.022]. GABA levels were significantly higher in the schizophrenia group compared with the healthy control group (p=0.002). Furthermore, Chlorpromazine equivalent doses of antipsychotics correlated with right hemisphere GABA levels (r2=0.68, p=0.006, n=33). GABA levels are elevated in the right hemisphere in patients with schizophrenia in comparison to bipolar disorder and healthy controls. The balance between excitatory and inhibitory controls over the cortical circuits may have direct relationship with GABAergic functions in auditory cortices. In addition, GABA levels may be altered by brain regions of interest, psychotropic medications, and clinical stage in schizophrenia and bipolar disorder. PMID:27890741

An association between anorexia nerviosa (AN) and low bone mass has been demonstrated. Bone loss associated with AN involves hormonal and nutritional impairments, though their exact contribution is not clearly established. We compared bone mass in AN patients with women of similar weight with no criteria for AN, and a third group of healthy, normal-weight, age-matched women. The study included forty-eight patients with AN, twenty-two healthy eumenorrhoeic women with low weight (LW group; BMI < 18.5 kg/m2) and twenty healthy women with BMI >18.5 kg/m2 (control group), all of similar age. We measured lean body mass, percentage fat mass, total bone mineral content (BMC) and bone mineral density in lumbar spine (BMD LS) and in total (tBMD). We measured anthropometric parameters, leptin and growth hormone. The control group had greater tBMD and BMD LS than the other groups, with no differences between the AN and LW groups. No differences were found in tBMD, BMD LS and total BMC between the restrictive (n 25) and binge-purge type (n 23) in AN patients. In AN, minimum weight (P = 0.002) and percentage fat mass (P = 0.02) explained BMD LS variation (r2 0.48) and minimum weight (r2 0.42; P = 0.002) for tBMD in stepwise regression analyses. In the LW group, BMI explained BMD LS (r2 0.72; P = 0.01) and tBMD (r2 0.57; P = 0.04). We concluded that patients with AN had similar BMD to healthy thin women. Anthropometric parameters could contribute more significantly than oestrogen deficiency in the achievement of peak bone mass in AN patients.

Leptin regulates the organism's immune response. Juvenile idiopathic arthritis (JIA) is a chronic joint disease in children, leading to chronic changes in motor organs. In children with JIA (n = 42) and healthy subjects (n = 28), leptin concentration (LEP), body mass index (BMI), haematocrit (HTC), haemoglobin (HB), morphotic elements (WBC,LYMPH), erythrocyte sedimentation rate (ESR), and ANA Hep-2 antibodies were analysed. JIA group was divided into: children with a longer (51-148 months) (IA) n = 22 and a shorter disease period (2-18 months) (IB) n = 20. Only 58.3% of the IA and 50% of the IB group had ANA Hep-2 confirmed. The ill children had higher and more diversified LYMPH and ESR levels compared to the healthy children. The highest LEP for the IA group was 37.5 ng/cm3, (Me 5.85), for IB - 40.10 ng/cm3, (Me 2.46) as compared to the IC - 3.74 ng/cm3 (Me 2.85), respectively. The average BMI value for the IA group was 16.61 kg/m2, for IC it was 18.91 kg/m2, and the median for IB was 15.89 kg/m2. Children with BMI values < 23 kg/m2 from the IA and IB group had a reduction in LEP as compared to control group (p = 0.04). The relationship between the illness and LEP diversification per BMI unit was found in both groups. Children with a shorter illness period had higher LEP differentiation per BMI unit compared to the healthy children. Children with juvenile idiopathic arthritis with BMI < 23 kg/m2 had lower leptin concentrations than healthy subjects. Ill children with a shorter-term disease had a higher diversification of leptin concentration per BMI unit as compared to healthy controls.

To determine the prevalence of celiac disease in children and adolescents with migraine, the authors investigated serum levels of tissue transglutaminase antibody immunoglobulin A and total immunoglobulin A from 81 children with migraine and in a healthy control group of 176 children. Study participants who were positive for tissue transglutaminase immunoglobulin A antibodies underwent a duodenal biopsy. Two patients in the migraine group (2.5%) and 1 in the control group (0.57%) tested positive for serum tissue transglutaminase immunoglobulin A antibodies (P > .05). Duodenal biopsy did not confirm celiac disease in both groups, and these patients were considered "potential celiac" cases. In the present study, children with migraine did not exhibit a higher prevalence rate of celiac disease compared with healthy controls. Therefore, the screening test for celiac disease is not a necessary part of the management of migraine in children. © The Author(s) 2016.

Background and Objectives The aim of this study was to investigate serum paraoxanase-1 (PON) activity, total oxidant status (TOS), total antioxidant status (TAS), and the oxidative stress index (OSI) in tinnitus; and to compare the results with data from healthy subjects. Subjects and Methods A total of 114 subjects-54 patients with tinnitus and 60 healthy controls were enrolled in this study. Serum PON activity, TOS, TAS, and OSI levels were measured. Results In the tinnitus group, TAS, and PON were significantly lower than in the control group (p<0.001). However, the TOS, and OSI levels were significantly higher in the tinnitus group than in the control group (p<0.001). Conclusions According to the data obtained from the present study, patients with tinnitus were exposed to potent oxidative stress. Oxidative stress may be the key contributing factor to the pathogenesis of tinnitus. PMID:27144229

In Finland, all men are liable to military service and a clear majority completes service. The increasing prevalence of obesity also among soldiers concerns conscripts' food choices. Conscripts are served nutritionally planned regular main meals but individual choices take place in free-time eating. This study assesses the effects in conscripts' eating habits in an intervention targeting the supply of healthy foods available in the military setting. Participants were 604 18-21-year old male conscripts of whom 242 belonged to Control Group and 362 to Intervention Group. Participants of Control Group were historical controls performing military service one year before Intervention Group. The intervention targeted selection, placement, and attractiveness of healthy foods in garrison refectories and soldier's home cafeterias, the two main food providers in the military. Dietary intake data was collected by self-administered questionnaire at three time points: before/beginning of military service (T0), 8 weeks (T1) and 6 months (T2) of military service. Outcome measures were food consumption frequencies and four dietary indexes (Cereal Index, Fruit and Vegetable Index, Fat Index and Sugar Index) developed to characterize the diet. Changes between study groups in outcome variables and in time were analysed by repeated-measures analysis of covariance. Significant (p < 0.05) intervention effects and time-intervention interactions mostly in favor of Intervention Group were found. In Intervention Group, Cereal Index was significantly higher at T2 and the overall level of porridges and cereals was higher during follow-up when comparing to Control Group. Also, the overall levels of Fat Index, potato chips, soft drinks and desserts as well as sweet pastries at T1 were significantly lower in Intervention Group. At the same time, Fruit and Vegetable Index and the level of fruit and berries were lower in Intervention Group during follow-up. In the military setting, healthier food choices can be promoted by intervening on the main food environments by improving the supply of healthy foods. However, impacting on conscripts' individual selection as fruit and vegetable consumption is more challenging.

Diabetes mellitus is an endocrine disease due to insufficiency production of insulin that is associated with altered quantity and quality in salivary secretion. Alteration in saliva can reflect the changes in patients' blood. The collection of saliva is easy therefore; the assessment of saliva is suitable for screening tests of large population. The study aimed at evaluate some elements in diabetic patients' saliva. A total of 25 diabetic patients and age-sex matched control group enrolled into the study. Absorbance spectrophotometer technique was used for assessment of some salivary elements. The assessment of saliva showed that diabetics had unstimulated salivary flow rate of 0.18 ± 0.14 mL/min compared to 0.30 ± 0.12 mL/min for healthy individuals (P<0.01). Secretion of potassium and urea to saliva was significantly higher in diabetics compared to healthy group (P<0.05). In contrast calcium, sodium and phosphorus concentration was not significantly different in two groups. The level of salivary urea, potassium and phosphorus was significantly elevated in diabetic males compared to healthy males and the level of salivary calcium in diabetic females was significantly reduced compared to healthy females (P<0.05). There was not any significant difference in salivary sodium of healthy and diabetic persons according to gender (P>0.05). The finding showed that there were some alterations in salivary elements in diabetic patients even in well-controlled subjects compared to healthy group. Moreover, some salivary elements concentrations were various in diabetic and healthy subjects regarding to the sex. Assessment of salivary composition could be beneficial in oral health evaluation.

There is an increasing amount of evidence which links the pathogenesis of irritable bowel syndrome (IBS) with food IgG hyperreactivity. Some authors have suggested that food IgG hyperreactivity could be also involved in the pathophysiology of major depressive disorder (MDD). The aim of this study was to compare levels of serum IgG against 39 selected food antigens between three groups of participants: patients with MDD (MDD group), patients with IBS (IBS group) and healthy controls (HC group). The study included 65 participants (22 in the MDD group, 22 in the IBS group and 21 in the HC group). Serum IgG levels were examined using enzyme-linked immunosorbent assay (ELISA). Medical records, clinical data and laboratory results were collected for the analysis. IgG food hyperreactivity (interpreted as an average of levels of IgG antibodies above 7.5 µg/mL) was detected in 28 (43%) participants, including 14 (64%) from the MDD group, ten (46%) from the IBS group and four (19%) from the HC group. We found differences between extreme IgG levels in MDD versus HC groups and in IBS versus HC groups. Patients with MDD had significantly higher serum levels of total IgG antibodies and IgG against celery, garlic and gluten compared with healthy controls. The MDD group also had higher serum IgG levels against gluten compared with the IBS group. Our results suggest dissimilarity in immune responses against food proteins between the examined groups, with the highest immunoreactivity in the MDD group. Further studies are needed to repeat and confirm these results in bigger cohorts and also examine clinical utility of IgG-based elimination diet in patients with MDD and IBS. PMID:29710769

Patient-Reported Outcome Measures in Individuals With Chronic Ankle Instability: A Systematic Review

Houston, Megan N.; Hoch, Johanna M.; Hoch, Matthew C.

2015-01-01

Context  A comprehensive systematic literature review of the health-related quality-of-life (HRQOL) differences among individuals with chronic ankle instability (CAI), ankle-sprain copers, and healthy control participants has not been conducted. It could provide a better indication of the self-reported deficits that may be present in individuals with CAI. Objective  To systematically summarize the extent to which HRQOL deficits are present in individuals with CAI. Data Sources  We searched for articles in the electronic databases of EBSCO Host and PubMed Central using key words chronic, functional, mechanical, coper, instability, sprains, and patient-assessed. We also performed a hand search of reference lists, authors, and patient-reported outcomes (PROs) of the articles screened for inclusion. Study Selection  Studies were included if they (1) incorporated a PRO as a participant descriptor or as a study outcome to compare adults with CAI to ankle-sprain copers or healthy controls, (2) were written in English, and (3) were published in peer-reviewed journals. Data Extraction  Two authors independently assessed methodologic quality using the modified Downs and Black Index. Articles were filtered into 3 categories based on between-groups comparisons: CAI and copers, CAI and healthy control participants, copers and healthy participants. We calculated Hedges g effect sizes and 95% confidence intervals to examine PRO group differences. Data Synthesis  Of the 124 studies assessed for eligibility, 27 were included. A total of 24 articles compared PROs in individuals with CAI and healthy controls, 7 compared individuals with CAI and copers, and 4 compared copers and healthy controls. Quality scores on the modified Downs and Black Index ranged from 52.9% to 88.2%, with 8 high-, 16 moderate-, and 3 low-quality studies. Overall, we observed moderate to strong evidence that individuals with CAI displayed deficits on generic and region-specific PROs compared with copers and healthy controls. However, evidence that differences exist between copers and healthy controls was conflicting. In addition, for dimension-specific outcomes, evidence to suggest that fear of reinjury is heightened in individuals with CAI was limited. Conclusions  The evidence suggested that CAI is associated with functional and HRQOL deficits, particularly when examined with region-specific PROs. However, PROs do not appear to differ between copers and healthy controls. PMID:26332028

The aim of this study was to investigate electroencephalogram (EEG) dynamics using complexity analysis in children with attention-deficit/hyperactivity disorder (ADHD) compared with healthy control children when performing a cognitive task. Thirty 7-12-year-old children meeting Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) criteria for ADHD and 30 healthy control children underwent an EEG evaluation during a cognitive task, and Lempel-Ziv complexity (LZC) values were computed. There were no significant differences between ADHD and control groups on age and gender. The mean LZC of the ADHD children was significantly larger than healthy children over the right anterior and right posterior regions during the cognitive performance. In the ADHD group, complexity of the right hemisphere was higher than that of the left hemisphere, but the complexity of the left hemisphere was higher than that of the right hemisphere in the normal group. Although fronto-striatal dysfunction is considered conclusive evidence for the pathophysiology of ADHD, our arithmetic mental task has provided evidence of structural and functional changes in the posterior regions and probably cerebellum in ADHD.

Children's consumption of restaurant foods is associated with higher energy intake and lower nutritional quality compared to foods prepared at home. The aim of this pilot study was to test whether an in-restaurant intervention promoting healthy children's meals (i.e. two meals that met nutrition recommendations and were thus healthier than typical children's meal offerings across leading restaurants) affected children's meal selection and intake. Families with 4-to-8-year-old children were recruited from one location of Anderson's Frozen Custard, a regional quick-service restaurant chain. Families were randomly assigned to return to the restaurant during an intervention or control period and were blinded to group assignment. All families received free meals. During the intervention period families also received placemats featuring two healthy "Kids' Meals of the Day" upon restaurant entry. After families finished dining, researchers recorded children's orders and collected leftovers for quantifying dietary intake via weighed plate waste. Poisson regression and chi-square tests were used to compare children's orders between study groups, and t-tests were used to test for differences in dietary intake among children ordering a promoted healthy entrée (main dish) versus those who did not. Fifty-eight families participated. Children who were exposed to the study placemats prior to ordering ordered a significantly greater number of healthy food components compared to controls (p = 0.03). Overall, in the intervention group, 21% of children ordered a healthy entrée or side dish, versus 7% of controls. Children who ordered one of the promoted healthy entrées consumed less saturated fat across the total meal compared to those who did not (p = 0.04). Manipulating the prominence of healthy choices in restaurants may shift children's meal selections. Future research should build on these initial promising results, aiming to increase the potency of the intervention to achieve more widespread effects. Copyright © 2018 Elsevier Inc.

A case-control study. To compare health-related quality of life and low back pain of healthy subjects with those of patients with nonidiopathic scoliosis (non-IS) and idiopathic scoliosis (IS) 21 years or more after surgery. There have been a very small number of reports on long-term results of surgery for non-IS. There have not been any reports that compare non-IS, IS, and healthy subjects. The subjects with scoliosis were 602 patients who had undergone surgery between 1968 and 1988. The Scoliosis Research Society Patient Questionnaire (SRS-22), Roland-Morris Disability Questionnaire (RDQ), and our institution's original questionnaire were used for evaluating long-term clinical outcomes. The 136 respondents consisted of 56 patients with non-IS (non-IS group) and 80 patients with IS (IS group). The control group (CTR group) consisted of 80 healthy volunteers who were age- and body mass index-matched to the scoliosis groups. In the SRS-22, the 3 groups had no significant differences in pain and mental health. For function and self-image, the non-IS group and the IS group had a significantly lower score than the CTR group. In the RDQ, the non-IS group had significantly more severe low back pain than the CTR group. There was no significant difference in low back pain between the non-IS group and IS group or between the IS group and CTR group. The non-IS group had a significantly lower marriage rate than the IS and CTR groups. The patients with non-IS and IS had similar health-related quality of life and low back pain. The patients with non-IS were found to have lower function and self-image in the SRS-22 questionnaire and more severe low back pain in the RDQ than healthy subjects. The patients with non-IS had a significantly lower marriage rate than the other 2 groups.

Chronic obstructive pulmonary disease (COPD) is a third leading cause of death. In this case control study, we prepared 5 cc bloods from the antecubital vein of 100 COPD patients and 40 healthy individuals as control group. Vascular endothelial growth factor (VEGF) expression protein level was measured by ELISA in both groups. We found that concentration of VEGF in blood serum of patients with COPD (189.9±16pg/ml) was significantly higher than the control group (16.4±3.48pg/ml) (p<0.001). While VEGF serum level in emphysematous patients wasn't significantly different with control group (p=0.07). Furthermore VEGF serum level in COPD patients was proportionally increased with severity of disease (p<0.001). Besides all COPD patients, regardless of their smoking status, were experienced significantly higher levels of VEGF than healthy ones (p=0.001; z=4.3). Our results suggest VEGF serum concentration as the sensitive index for severity and activity of COPD and its prognosis.

To investigate choroidal thickness using enhanced-depth imaging optical coherence tomography in paediatric patients with adenotonsillar hypertrophy, with comparison to healthy children, three months after adenotonsillectomy. The patients were assigned to three groups: an adenotonsillar hypertrophy group, an adenotonsillectomy group and a healthy control group. In all groups, subfoveal, temporal and nasal choroidal thickness measurements were taken. In the subfoveal, temporal and nasal regions, choroidal tissue was found to be significantly thinner in adenotonsillar hypertrophy children than healthy children (p = 0.012, p = 0.027 and p = 0.020). The subfoveal and temporal choroidal thickness measurements of adenotonsillar hypertrophy group cases were significantly decreased compared to those in the adenotonsillectomy group (p = 0.038 and p = 0.048). There was a significant association between decreased choroidal thickness and adenotonsillar hypertrophy. Adenotonsillar hypertrophy may play an important role in decreased choroidal thickness.

Background This case-control study concerns a molecular biological method based on the data gathered from a group of Korean subjects to examine the distribution of Malassezia yeasts in seborrheic dermatitis (SD) patients. Cultures for Malassezia yeasts were taken from the foreheads, cheeks and chests of 60 patients with SD and in 60 healthy controls of equivalent age. Objective The purpose of this study is to identify the relationship between certain species of Malassezia and SD. This was done by analyzing the differences in the distribution of Malassezia species in terms of age and body parts of the host with healthy controls. Methods 26S rDNA PCR-RFLP, a fast and accurate molecular biological method, was used to overcome the limits of morphological and biochemical methods. Results The positive Malassezia culture rate was 51.7% in patients with SD, which was lower than that of healthy adults (63.9%). M. restricta was dominant in patients with SD (19.5%). Likewise, M. restricta was identified as a common species (20.5%) in healthy controls. In the ages 31~40, M. restricta was found to be the most common species (31.6%) among SD patients. Conclusion According to the results of the study, the most frequently isolated species was M. restricta (19.5%) in patients with SD. There was no statistically significant difference in the distribution of Malassezia species between the SD patients and healthy control groups. PMID:20548904

The recent rapid increase in childhood obesity rates suggests that a consideration of the role of the schools in addressing this problem is necessary. 'Fits me' program functions to promote eating daily and healthy breakfast among elementary school children. Separate children groups were sampled each year by clusters from seven regions around Israel. They filled a self-administered questionnaire at the beginning of 2003, before the program started, and in 2003-2005, after the program. A separate sample was collected in 2006 in a case-control structure. The answer to the question: 'what do you eat for breakfast?' considered as a healthy breakfast if it included one of the following food items: A sandwich (not including chocolate, jam or butter), cereals, vegetable, fruit, egg and dairy product. As compared with 2003 before the program, more children reported eating daily breakfast over the years (51-65% before and until 2005, respectively, P for trend<0.01). Odds ratio (OR) and 95% confidence interval (95% CI) for eating a healthy breakfast, in 2006 in the intervention (n=417) vs controls (n=572), adjusted for sex and age were OR=1.53 (95% CI: 1.15-2.04). However, only a third of 75% of the children who ate a healthy breakfast in the intervention group estimated that they were eating a healthy breakfast. After implementation an educational program to promote daily and healthy breakfast eating, the goal of a healthier breakfast was achieved. However, one should strive to define an exact definition of a healthy breakfast.

This study assessed the efficacy of a school-based healthy lifestyle intervention (Sport for LIFE) for increasing physical activity, decreasing sedentary behaviour, reducing screen time behaviour, encouraging healthy attitudes and behaviour to nutrition, and reducing body mass index (BMI) in 8-9-year-old primary school children from lower socioeconomic backgrounds in Northern Ireland. A non-randomised controlled trial of 416 children from 24 schools took part. Schools were randomly assigned to one of two groups, an intervention or control group with 12 schools in each group. The intervention group received a 12-week school-based programme based on social cognitive theory. At baseline and follow-up, groups completed questionnaires assessing physical activity, screen time behaviour and dietary patterns. On each occasion anthropometric assessments of height and weight were taken. Physical activity and sedentary behaviour were measured by accelerometry. Significant effects were observed for vigorous, moderate and light activity for the intervention group at follow-up. Sedentary behaviour was significantly reduced for the intervention group but not for the control group. No significant effects of the intervention on BMI, screen time behaviour or attitudes to nutrition, with the exception of non-core foods, were shown. The programme was effective in increasing physical activity and reducing sedentary behaviour, however no significant changes in screen time behaviour and attitude to nutrition, with the exception of non-core foods, were observed. Future research ideas are offered for tackling low levels of physical activity in children.

Urban bus operators are an occupational group with high rates of overweight and obesity. Understanding methods bus operators use for weight control may be important; there may be increased risk for these workers to engage in less healthy weight management behaviours due to stressful working conditions. To examine the prevalence of unhealthy and healthy weight control behaviours used by bus operators and examine associations between use of unhealthy weight control behaviours and work-related and sociodemographic variables. Bus operators from four different transit garages were invited to complete a self-administered survey; height and weight were measured by research staff. Unhealthy and healthy weight control behaviours, work hours, work schedule and social support were measured with self-report items on the employee survey. Logistic regression analysis was conducted to estimate associations. Nearly 60% of bus operators endorsed at least one unhealthy method; over 50% reported skipping meals, 30% fasted and 10% reported taking diet pills in the past year. Bus operator gender, race, body mass index status and hours worked per week showed significant associations with using at least one unhealthy weight control behaviour. Worksite interventions should emphasize the benefit of healthy eating and physical activity but should also address the use of less healthy methods for weight control for individuals employed in transportation occupations.

OBJECTIVE To examine bile acid composition of gallbladder contents in dogs with gallbladder mucocele and biliary sludge. ANIMALS 18 dogs with gallbladder mucocele (GBM group), 8 dogs with immobile biliary sludge (i-BS group), 17 dogs with mobile biliary sludge (m-BS group), and 14 healthy dogs (control group). PROCEDURES Samples of gallbladder contents were obtained by use of percutaneous ultrasound-guided cholecystocentesis or during cholecystectomy or necropsy. Concentrations of 15 bile acids were determined by use of highperformance liquid chromatography, and a bile acid compositional ratio was calculated for each group. RESULTS Concentrations of most bile acids in the GBM group were significantly lower than those in the control and m-BS groups. Compositional ratio of taurodeoxycholic acid, which is 1 of 3 major bile acids in dogs, was significantly lower in the GBM and i-BS groups, compared with ratios for the control and m-BS groups. The compositional ratio of taurocholic acid was significantly higher and that of taurochenodeoxycholic acid significantly lower in the i-BS group than in the control group. CONCLUSIONS AND CLINICAL RELEVANCE In this study, concentrations and fractions of bile acids in gallbladder contents were significantly different in dogs with gallbladder mucocele or immobile biliary sludge, compared with results for healthy control dogs. Studies are needed to determine whether changes in bile acid composition are primary or secondary events of gallbladder abnormalities.

The aim of this study was to compare serum brain-derived neurotrophic factor (BDNF) levels between adolescents that harm themselves, those that receive psychiatric treatment but do not harm themselves, healthy adolescents, and childhood traumas and to investigate the relationship between traumatic experiences and serum BDNF levels. The cases were divided into two groups of 40 adolescents exhibiting self-harm behavior (self-harm/diagnosed group) and 30 adolescents receiving psychiatric treatment but not exhibiting self-harm behaviors (non self-harm/diagnosed group). The control group (healthy control group) consisted of 35 healthy adolescents with no psychiatric disorders or self-harm behaviors. The adolescents were asked to fill in the Inventory of Statements About Self Injury (ISAS) and Childhood Trauma Questionnaire (CTQ). For BDNF measurement, blood samples were taken from the cases and controls. The serum BDNF level of self-harming adolescents who used the self-cutting method was significantly lower than that of other groups, and serum BDNF levels decreased with the increase in the emotional neglect and abuse severity of self-harming adolescents during childhood. In our study, serum BDNF levels decreased with the increase in emotional abuse in self-harming adolescents. This finding may indicate that neuroplasticity can be affected by a negative emotional environment during the early period. Copyright © 2017 Elsevier B.V. All rights reserved.

To compare the effects of vision and cognitive load on static postural control in subjects with and without patellofemoral pain syndrome (PFPS). Twenty-eight PFPS patients and 28 controls participated in the study. Postural control was assessed in isolation as well as with visual manipulation and cognitive loading on symptomatic limb. The outcome measures of postural control were quantified in terms of area, anterior-posterior (AP), medial-lateral (ML), and mean velocity (MV) of the displacements of center of pressure (COP). In addition, cognitive performance (auditory Stroop task) was measured in the forms of average reaction time and error ratio in baseline (sitting) and different postural conditions. PFPS subjects showed greater increases in area (p = 0.01), AP (p = 0.01), and ML (p = 0.05) displacements of COP in the blindfolded tasks as compared to control group. However, cognitive load did not differently affect postural control in the two groups. Although PFPS and control group had similar reaction times in the sitting position (p = 0.29), PFPS subjects had longer reaction times than healthy subjects in dual task conditions (p = 0.04). Visual inputs seem to be essential for discriminating postural control between PFPS and healthy individuals. PFPS patients biased toward decreasing cognitive performance more than healthy subjects when they perform the single leg stance and cognitive task concurrently.

To quantify and compare the amounts of surfactant proteins SP-A, SP-B, SP-C and SP-D in the tear fluid collected from patients with dry eye syndrome and from individuals with a healthy ocular surface. Schirmer strips were used to collect tear fluid from both eyes of 241 volunteers (99 men, 142 women; age range: 18-87 years). Dry eye syndrome was diagnosed by ophthalmologists in 125 patients, whereas the healthy control group comprised 116 individuals. The total protein concentration was determined via Bradford assay. The relative concentration of surfactant proteins SP-A through -D was measured by enzyme-linked immuno-sorbent assay (ELISA). The mean relative concentrations of SP-A, SP-C and SP-D were significantly higher in the dry eye group as compared to the healthy controls (p<0.05, one-way ANOVA). SP-B was also detected at a higher concentration in the dry eye group, but the difference to the control group was not statistically significant. The upregulation of SP-A and SP-D in the dry eye group is probably related to these proteins' known antimicrobial and immunomodulatory effects at the ocular surface. It may represent a pathophysiological response to the inflammatory condition of the ocular surface in dry eye. The upregulation of SP-B and SP-C may represent an effort of the lacrimal system to reduce surface tension and thus to counteract the increased tendency of the tear film to tear in dry eye.

To compare the biochemical and immunological profiles of pediatric patients with acute myeloid leukemia (AML) with healthy children and adolescents. This was a cross-sectional study in which 21 therapy-naïve patients with AML were compared with a group of 24 healthy individuals. The following data were analyzed: serum proteins, leucocytes and subgroups, erythrocytes, hematocrit, hemoglobin, platelets, cytokines in peripheral blood mononuclear cells cultures under spontaneous and BCG- or PHA-stimulated conditions, immunoglobulin A, and erythrocytic glutathione. Statistical analysis was performed using SPSS software, considering as significant p-values<0.05. Serum albumin levels were higher (p<0.0001) in the control group, as well as all the parameters related to red blood cells (p<0.0001). For leucocytes and subgroups, no statistical difference was found between the AML and the control groups. For cytokines, the concentrations were significantly higher under spontaneous and BCG-stimulated conditions for TNF-α, IL-6, IL-10, and IFN-γ in the control group. Under PHA-stimulated conditions, the concentration was higher (p=0.002) only for IL-6. No difference was found between the two groups for the other cytokines and for IgA in the saliva. Erythrocytic glutathione was higher (p<0.0001) in AML patients. It was possible to characterize the biochemical and immunological profile of pediatric patients with AML, as well as highlight some significant differences in these parameters when comparing with healthy children and adolescents.

Is there an association of ABO blood groups and Rhesus factor with alopecia areata?

PubMed

İslamoğlu, Zeynep Gizem Kaya; Unal, Mehmet

2018-01-15

Alopecia areata (AA) is an autoimmune disease characterized by noncicatricial hair loss localized on hair, beard, mustache, eyebrow, eyelash, and sometimes on the body. Although etiopathogenesis is not fully understood, many studies show remarkable associations between various diseases and ABO blood groups. However, there is no study with AA and blood groups. Healthy people and patients with AA were included in this study. A total of 155 patients with AA and 299 healthy controls were included in the study. ABO blood group distribution in patients with AA and distribution of healthy donors were similar. However, Rhesus factor positivity in the AA group was significantly higher than in healthy donors. The relationship between stress and AA was high as known. But, ABO blood group and Rhesus factor were not in a significant connection with stress. We conclude that there was no association between ABO blood group and AA, but the observed distribution of Rhesus blood group differed slightly but significantly from that of the healthy population. The result of the study shows a small but statistically significant difference in the Rh blood group between patients with AA and the healthy population blood groups. This result is important because it suggests that genetic factors may influence the development of AA. The role of blood groups in the development of AA remains to be determined. We believe that the studies which will be carried out in other centers with wider series will be more valuable to support this hypothesis. © 2018 Wiley Periodicals, Inc.

The aim of this study was to determine whether detectable periodontal destruction and alterations in the salivary status were present with duration of diabetes in children with type 1 insulin-dependent diabetes mellitus (type 1 DM) as compared to healthy controls. Sixteen newly diagnosed children with DM (group 1), 16 children with type 1 DM of long duration (group 2), and 16 healthy children (group 3) participated in the study. Periodontal health was assessed by plaque index, gingival index, bleeding on probing, and periodontal probing depths. The flow rate, pH, buffering capacity, and peroxidase activities of stimulated saliva were determined. The data were analyzed by Kruskall-Wallis, Student t test, and Pearson's correlation analysis. The mean values for fasting blood glucose levels for the diabetic groups were significantly higher than for the controls. The mean values for salivary buffering capacities and salivary pH from the diabetic groups were significantly lower than for the controls. The plaque index values for the diabetic groups were significantly higher than for the controls. The mean gingival index value for group 1 was significantly lower than for group 2. The mean periodontal probing depths for group 1 were similar to those of the non-DM controls, but the mean periodontal probing depths for group 2 were significantly greater than for both the non-DM controls and group 1. Group 1 had significantly greater bleeding on probing scores than did the other groups (P < 0.05). The glycemic status of the diabetic subjects affects the periodontal probing depths, salivary pH, buffering capacity, and peroxidase activity.

The purpose of this study was to know if peri-implantitis causes an increase in the total salivary concentration of oxidative stress markers. Seventy patients, 28 men and 42 women, 60 of them with dental implants, 30 of which had peri-implantitis and 30 were healthy. The remaining 10 were the control group: healthy subjects without implants. The average number of implants per patient was 4.70 ± 2.29 in the peri-implantitis group and 2 70 ± 2.11 in the control group. Periodontal/peri-implant variables were assessed, including bleeding index, gingival index, clinical attachment level, probing depth, presence of pockets larger than 4 and 6 mm, pain to percussion, suppuration, gingival hyperplasia or granuloma, crestal bone loss (both mesially and distally), evaluated through periapical radiography. Saliva samples from the 70 subjects were collected for measurement of malondialdehyde high performance liquid chromatography (HPLC) and myeloperoxidase (enzyme-linked immunosorbent assay analysis) concentrations. Implants affected with peri-implantitis had an average follow-up of 26.40 ± 7.97 months. 4.12% of implants with peri-implantitis had a painful response to percussion. 2.06% showed suppuration; 25.77% had granuloma. The mean crestal bone loss in implants wtih peri-implantitis was 3.78 ± 1.17 mm. Total salivary malondialdehyde concentration in the peri-implantitis group (0.52 ± 0.37 μM/l) was slightly higher than that in the group with healthy implants (0.40 ± 0.16 μM/l) and also slightly higher than that in the group of healthy patients without implants (0.41 ± 0.79 μM/l), although the difference was not statistically significant, p value = .442. Myeloperoxidase concentration was slightly higher in the peri-implantitis group (12.32 ± 2.17 ng/ml) than in the group with healthy implants (11.54 ± 2.80 ng/ml) and the group of healthy patients without implants (11.86 ± 2.67 ng/ml), without statistically significant differences, p value = .584. The salivary concentration of oxidative stress markers in patients with peri-implantitis and without periodontitis is not higher than that found in healthy patients. © 2015 Wiley Periodicals, Inc.

The goals of this study were to establish prevalence of subjective memory complaints (SMC) and depressive symptoms (DS) and their relation to cognitive functioning and cognitive status in an outpatient memory clinic cohort. Two hundred forty-eight cognitively healthy controls and 581 consecutive patients with cognitive complaints who fulfilled the inclusion criteria were included in the study. A statistically significant difference (p < 0.001) between control group and patient group regarding mean SMC was detected. 7.7% of controls reported a considerable degree of SMC, whereas 35.8% of patients reported considerable SMC. Additionally, a statistically significant difference (p < 0.001) between controls and patient group regarding Beck depression score was detected. 16.6% of controls showed a clinical relevant degree of DS, whereas 48.5% of patients showed DS. An analysis of variance revealed a statistically significant difference across all four groups (control group, SCI group, naMCI group, aMCI group) (p < 0.001). Whereas 8% of controls reported a considerable degree of SMC, 34% of the SCI group, 31% of the naMCI group, and 54% of the aMCI group reported considerable SMC. A two-factor analysis of variance with the factors cognitive status (controls, SCI group, naMCI group, aMCI group) and depressive status (depressed vs. not depressed) and SMC as dependent variable revealed that both factors were significant (p < 0.001), whereas the interaction was not (p = 0.820). A large proportion of patients seeking help in a memory outpatient clinic report considerable SMC, with an increasing degree from cognitively healthy elderly to aMCI. Depressive status increases SMC consistently across groups with different cognitive status.

Sensory augmentation has been shown to improve postural stability during real-time balance applications. Limited long-term controlled studies have examined retention of balance improvements in healthy older adults after training with sensory augmentation has ceased. This pilot study aimed to assess the efficacy of long-term balance training with and without sensory augmentation among community-dwelling healthy older adults. Twelve participants (four males, eight females; 75.6 ± 4.9 yrs) were randomly assigned to the experimental group (n = 6) or control group (n = 6). Participants trained in their homes for eight weeks, completing three 45-min exercise sessions per week using smart phone balance trainers that provided written, graphic, and video guidance, and monitored trunk sway. During each session, participants performed six repetitions of six exercises selected from five categories (static standing, compliant surface standing, weight shifting, modified center of gravity, and gait). The experimental group received vibrotactile sensory augmentation for four of the six repetitions per exercise via the smart phone balance trainers, while the control group performed exercises without sensory augmentation. The smart phone balance trainers sent exercise performance data to a physical therapist, who recommended exercises on a weekly basis. Balance performance was assessed using a battery of clinical balance tests (Activity Balance Confidence Scale, Sensory Organization Test, Mini Balance Evaluation Systems Test, Five Times Sit to Stand Test, Four Square Step Test, Functional Reach Test, Gait Speed Test, Timed Up and Go, and Timed Up and Go with Cognitive Task) before training, after four weeks of training, and after eight weeks of training. Participants in the experimental group were able to use vibrotactile sensory augmentation independently in their homes. After training, the experimental group had significantly greater improvements in Sensory Organization Test and Mini Balance Evaluation Systems Test scores than the control group. Significant improvement was also observed for Five Times Sit to Stand Test duration within the experimental group, but not in the control group. No significant improvements between the two groups were observed in the remaining clinical outcome measures. The findings of this study support the use of sensory augmentation devices by community-dwelling healthy older adults as balance rehabilitation tools, and indicate feasibility of telerehabilitation therapy with reduced input from clinicians.

Infantile autism is a common disorder of mental development, which is characterized by impairments in the communicative, cognitive and speech spheres and obsessional stereotyped behaviour. Although in most cases, pathogenic factors remain unclear, infantile autism has a significant hereditary component, however, its etiology is also under the influence of environmental factors, including the condition of the mother's body during pregnancy ("maternal effect"). Oxidative stress is assumed to play a key role in the pathogenesis of infantile autism. It is known that oxidative stress has a prominent genotoxic effect, which is realized through inducing single and double strand breaks of the nuclear DNA. We evaluated the degree of DNA damage in patients with infantile autism and their mothers using DNA comet assay. The comet tail moment and DNA per cent ratio in the tail were assessed for each individual. The two parameters appeared to be strongly correlated (r=0.90). Mean and median values of both parameters were considerably higher in the sample of autistic children, than in age-matching healthy controls. Interestingly, these parameters were also elevated in healthy mothers of autistic children, with no difference from the values in the group of autistic children. The control group of healthy women of reproductive age, who had no children with autism, differed by the DNA comet tail moment from the group of mothers of autistic children, but did not differ significantly from the control group of healthy children. The results suggest that there are genotoxic factors in mentally healthy mothers of autistic children, which can determine the pathological process in the foeti via environmental "maternal effect" during gestation.

Therapy Preferences in Melanoma Treatment - Willingness to Pay and Preference of Quality versus Length of Life of Patients, Physicians and Healthy Controls

PubMed Central

Krammer, Ramona; Heinzerling, Lucie

2014-01-01

Background New melanoma therapies, like e.g. ipilimumab, improve survival. However, only a small subset of patients benefits while 60% encounter side effects. Furthermore, these marginal benefits come at a very high price of €110’000 per treatment. This study examines attitudes towards melanoma therapy options of physicians, healthy individuals and patients, their willingness to pay and preference of quality versus length of life. Methods Based on findings from a focus group questionnaires were developed and pretested. After obtaining ethical approval and informed consent surveys were conducted in a total of 90 participants (n = 30 for each group). Statistical analyses were conducted using R. Findings Attitudes vastly differed between healthy participants, physicians and melanoma patients. Whereas melanoma patients show a high willingness to endure side effects despite very small survival gains (down to 1 extra week) or even only hope with no survival benefit, healthy controls are more critical, while physicians are the most therapy adverse. Consequently, if given €100’000 and the free decision what to spend the money on the willingness to pay for therapy was much higher in the patient group (68%) compared to 28% of healthy controls and only 43% of the physicians, respectively. When lowering the amount of cash that could be received instead of ipilimumab to €50’000 or €10’000 to test price sensitivity 69% (+1%) and 76% (+8%) of melanoma patients, respectively, preferred ipilimumab over cash. When judging on societal spending even melanoma patients opted for spending on ipilimumab in only 21%. Conclusion The judgment about the benefits of new treatment options largely differs between groups, physicians being the most critical against therapy. Price elasticity was low. PMID:25369124

Rey's Auditory Verbal Learning Test (RAVLT) is a widely used neuropsychological test to assess episodic memory. In the present study we sought to establish normative and discriminative validity data for the RAVLT in the elderly population using previously adapted learning lists for the Greek adult population. We administered the test to 258 cognitively healthy elderly participants, aged 60-89 years, and two patient groups (192 with amnestic mild cognitive impairment, aMCI, and 65 with Alzheimer's disease, AD). From the statistical analyses, we found that age and education contributed significantly to most trials of the RAVLT, whereas the influence of gender was not significant. Younger elderly participants with higher education outperformed the older elderly with lower education levels. Moreover, both clinical groups performed significantly worse on most RAVLT trials and composite measures than matched cognitively healthy controls. Furthermore, the AD group performed more poorly than the aMCI group on most RAVLT variables. Receiver operating characteristic (ROC) analysis was used to examine the utility of the RAVLT trials to discriminate cognitively healthy controls from aMCI and AD patients. Area under the curve (AUC), an index of effect size, showed that most of the RAVLT measures (individual and composite) included in this study adequately differentiated between the performance of healthy elders and aMCI/AD patients. We also provide cutoff scores in discriminating cognitively healthy controls from aMCI and AD patients, based on the sensitivity and specificity of the prescribed scores. Moreover, we present age- and education-specific normative data for individual and composite scores for the Greek adapted RAVLT in elderly subjects aged between 60 and 89 years for use in clinical and research settings.

Deng, Ke; Ouyang, Xiang Ying; Chu, Yi; Zhang, Qian

To analyse the microbiome composition of health and gingivitis in Chinese undergraduates with high-throughput sequencing. Sequencing of 16S rRNA gene amplicons was performed with the MiSeq system to compare subgingival bacterial communities from 54 subjects with gingivitis and 12 periodontally healthy controls. A total of 1,967,372 sequences representing 14 phyla, 104 genera, and 96 species were detected. Analysis of similarities (Anosim) test and Principal Component Analysis (PCA) showed significantly different community profiles between the health control and the subjects with gingivitis. Alpha-diversity metrics were significantly higher in the subgingival plaque of the subjects with gingivitis compared with that of the healthy control. Overall, the relative abundance of 35 genera and 46 species were significantly different between the two groups, among them 28 genera and 45 species showed higher relative abundance in the subjects with gingivitis, whereas seven genera and one species showed a higher relative abundance in the healthy control. The genera Porphyromonas, Treponema, and Tannerella showed higher relative abundance in the subjects with gingivitis, while the genera Capnocytophaga showed higher proportions in health controls. Porphyromonas gingivalis, Prevotella intermedia and Porphyromonas endodontalis had higher relative abundance in gingivitis. Among them, Porphyromonas gingivalis was most abundant. Our results revealed significantly different microbial community composition and structures of subgingival plaque between subjects with gingivitis and healthy controls. Subjects with gingivitis showed greater taxonomic diversity compared with periodontally healthy subjects. The proportion of Porphyromonas, especially Porphyromonas gingivalis, may be associated with gingivitis subjects aged between 18 and 21 years old in China. Adults with gingivitis in this age group may have a higher risk of developing periodontitis.

It is well known that brain structures correlate with intelligence but the association between the integrity of brain white matter tracts and intelligence in patients with mental retardation (MR) and healthy adults remains unknown. The aims of this study are to investigate whether the integrity of corpus callosum (CC), cingulum, uncinate fasciculus (UF), optic radiation (OR) and corticospinal tract (CST) are damaged in patients with MR, and to determine the correlations between the integrity of these tracts and full scale intelligence quotient (FSIQ) in both patients and controls. Fifteen MR patients and 79 healthy controls underwent intelligence tests and diffusion tensor imaging examinations. According to the FSIQ, all healthy controls were divided into general intelligence (GI: FSIQ<120; n=42) and high intelligence (HI: FSIQ> or =120; n=37) groups. Intelligence was assessed by Chinese Revised Wechsler Adult Intelligence Scale, and white matter tract integrity was assessed by fractional anisotropy (FA). MR patients showed significantly lower FA than healthy controls in the CC, UF, OR and CST. However, GI subjects only demonstrated lower FA than HI subjects in the right UF. Partial correlation analysis controlling for age and sex showed that FSIQ scores were significantly correlated with the FA of the bilateral UF, genu and truncus of CC, bilateral OR and left CST. While FSIQ scores were only significantly correlated with the FA of the right UF when further controlling for group. This study indicate that MR patients show extensive damage in the integrity of the brain white matter tracts, and the right UF is an important neural basis of human intelligence.

Perinatal HIV is associated with significant neurocognitive morbidities, but few studies have examined cognitive impact of early HIV infection on patients surviving to adulthood. The purpose of this study was to evaluate neurocognitive outcomes among a cohort of perinatally infected young adults. Individuals between the ages of 18 and 24 with perinatal infection were recruited for this cross-sectional study along with similarly aged healthy controls. Participants completed an MRI and brief neuropsychological assessment battery. Multivariate analysis of covariance controlling for age, gender, race/ethnicity, and education was completed to detect differences between the HIV+ and control groups. Multivariable linear regression was performed to assess HIV-associated factors potentially impacting neuropsychological findings among the HIV+ group. Twenty-nine HIV+ young adults and 13 healthy controls were included in the study. After adjusting for age and sociodemographic variables, the HIV+ group scored lower on attention/working memory (Digit Span (p = .008) and Letter-Number Sequencing (p = .038)), set-shifting (DKEFS Trail Making Test Condition 4 (p = .026) and motor speed (DKEFS Trail Making Test Condition 5 (p = .003)). For the HIV+ group, nadir CD4 was associated with better Letter-Number Sequencing score (p = .029) and use of highly active antiretroviral therapy was associated with better performance on Category Fluency (p = .040). After controlling for sociodemographic variables, executive dysfunction persists among young adults with perinatal HIV infection in comparison to controls. Future studies to further elucidate the impact of executive dysfunction on independent living and functional outcomes are indicated.

Cross-linked hyaluronic acid (HA) gel is widely used in esthetic medicine. Late bacterial infection (LBI) is a rare, but severe complication after HA augmentation. The aim of this study was to determine whether patients who underwent the HA injection procedure and developed LBI had qualitatively different bacterial flora on the skin compared to patients who underwent the procedure without any complications. The study group comprised 10 previously healthy women with recently diagnosed, untreated LBI after HA augmentation. The control group comprised 17 healthy women who had a similar amount of HA injected with no complications. To assess the difference between the two groups, their skin flora was cultured from nasal swabs, both before and after antibiotic treatment in the study group. A significant increase in the incidence of Staphylococcus epidermidis was detected in the control group ( P =0.000) compared to the study group. The study group showed a significantly higher incidence of Staphylococcus aureus ( P =0.005), Klebsiella pneumoniae ( P =0.006), Klebsiella oxytoca ( P =0.048), and Staphylococcus haemolyticus ( P =0.048) compared to the control group. The bacterial flora on the skin differed in patients with LBI from the control group. The control group's bacterial skin flora was dominated by S. epidermidis . Patients with LBI had a bacterial skin flora dominated by potentially pathogenic bacteria.

AIM: To investigate the effect of a four-week consumption of a special Hungarian probiotic agent (Biofir®) on the faecal microflora in human healthy subjects. METHODS: The effect of Biofir® with 106/cm3 initial germs on the faecal microflora was studied in 120 healthy volunteers (71 females, 49 males). The traditional Russian type kefir was used as control. The various germ groups and pH values were determined in wk 2, 4 and 6. RESULTS: The number of all microbes increased during the 4-week probiotic treatment. The number of microbes increased 4.3-fold in the control group and 6.8-fold in Biofir-treated group. The probiotic kefir caused multiplication of the probiotic flora, meanwhile the undesired bacteria multiplied in the control group. No significant change of pH values of the faeces was found in both groups. CONCLUSION: The Hungarian probiotic kefir (Biofir®) is capable of promoting multiplication of probiotic bacterial flora in the large bowel. PMID:16534858

Effects of short term water immersion on peripheral reflex excitability in hemiplegic and healthy individuals: A preliminary study

Background: Reflex excitability is increased in hemiplegic patients compared to healthy controls. One challenge of stroke rehabilitation is to decrease the effects of hyperreflexia, which may be possible with water immersion. Methods/Aims: The present study examined the effects of acute water immersion on electrically-evoked Hmax:Mmax ratios (a measure of reflex excitability) in 7 hyperreflexive hemiplegic patients and 7 age-matched healthy people. Hmax:Mmax ratios were measured from soleus on dry land (L1), immediately after (W1) and 5 minutes after immersion (W5), and again after five minutes on land (L5). Results: Water immersion led to an acute increase in Hmax:Mmax ratio in both groups. However, after returning to dry land, there was a non-significant decrease in the Hmax:Mmax ratio of 8% in the hemiplegic group and 10% in healthy controls compared to pre-immersion values. Interpretation: A short period of water immersion can decrease peripheral reflex excitability after returning to dry land in both healthy controls and post-stroke patients, although longer immersion periods may be required for sustainable effects. Water immersion may offer promise as a low-risk, non-invasive and non-pharmaceutical method of decreasing hyperreflexivity, and could thus support aquatic rehabilitation following stroke.

The potential contribution of psychological and anatomical changes to sexual dysfunction in female patients following short-term preoperative radiotherapy (5 x 5 Gy) and total mesorectal excision (TME) is not clear. Aim. In this study we assessed female sexual dysfunction in patients who underwent radiotherapy and TME for rectal cancer. Genital arousal was assessed using vaginal videoplethysmography. Sexual functioning was examined in four patients who had rectal cancer and underwent radiotherapy and TME. All investigations were done at least 15 months after treatment. The results were compared with an age-matched group of 18 healthy women. The patients and healthy controls showed comparable changes in vaginal vasocongestion during sexual arousal, though three out of four patients showed a lower mean spectral tension (MST) of the vaginal pulse compared with healthy controls. Subjective sexual arousal was equivalent between the two groups. In this study the changes of genital and subjective sexual arousal after erotic stimulus condition between patients and healthy controls were not different, though lower MST of the vaginal pulse was found in three out of four patients compared with healthy women. Additional work, however, must be performed to clarify the mechanisms of sexual dysfunction following treatment of rectal cancer.

In study 1, tongue-disabled patients with symptoms of dysphagia and dysarthria (n=11) and age- and sex-matched controls (n=11) participated in tongue training. In study 2, healthy elderly persons (n=16) and healthy young persons (n=16) volunteered. In study 1 and study 2, the tongue training lasted 30 and 40 minutes, respectively. Participants were instructed to play a computer game with the tongue using TDS. Motor performance was compared between groups in both studies. Correlation analyses were performed between age and relative improvement in performance. Subject-based reports of motivation, fun, pain, and fatigue evaluated on 0-to-10 numeric rating scales were compared between groups. In study 1, tongue-disabled patients performed poorer than healthy controls (P=.005) and with a trend of a sex difference (P=.046). In study 2, healthy young participants performed better than healthy elderly participants (P<.001), but there was no effect of sex (P=.140). There was a significant negative correlation between age and relative improvement in performance (δ=-.450; P=.009). There were no significant differences in subject-based reports of motivation, fun, pain, and fatigue between groups in any of the studies (P>.094). The present study provides evidence that tongue disability and age can influence behavioral measures of tongue motor performance. TDS may be a new adjunctive neurorehabilitation regimen in treating tongue-disabled patients. Copyright © 2014 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

Subpopulations of peripheral leukocytes and cytokine mRNA expression levels were evaluated in scouring and healthy Holstein calves (age 10 ± 5 days; n=42) treated with a probiotic consisting of Lactobacillus plantarum, Enterococcus faecium and Clostridium butyricum. The calves were assigned to the scouring or healthy group and then subdivided into pathogen-positive treated (n=8), pathogen-positive control (n=8), pathogen-negative treated (n=6), pathogen-negative control (n=6), healthy treated (n=6) and healthy control (n=8) groups. A single dose of the probiotic (3.0 g/100 kg body weight) was given to each calf in the treatment groups for 5 days. Blood samples were collected on the first day of scour occurrence (day 0) and on day 7. In the scouring calves, smaller peripheral leukocyte subpopulations and cytokine mRNA expression levels were noted on day 0. The numbers of CD3(+) T cells; CD4(+), CD8(+) and WC1(+) γδ T cell subsets; and CD14(+), CD21(+) and CD282(+) (TLR2) cells were significantly increased in the scouring and healthy treated calves on day 7. Furthermore, interleukin-6, tumor necrosis factor-alpha and interferon-gamma mRNA expression was elevated in the peripheral leukocytes of the scouring and healthy treated calves on day 7. The scouring calves given the probiotic recovered on day 7. A significantly smaller number of peripheral leukocytes and lower cytokine mRNA expression level might be induced by scouring in calves. Repeated probiotic administration might stimulate cellular immunity and encourage recovery from scouring in pre-weaning Holstein calves.

The aim of this study was to evaluate patients with Cushing's disease (CD) who had undergone transsphenoidal surgery in terms of depression, quality of life (QoL), and perception of body image in comparison to healthy controls. Forty patients with CD and 40 healthy controls matched for demographic characteristics were included in the study. The subjects were evaluated with the Beck depression inventory (BDI), the health survey-short form (SF-36) and the multidimensional body-self relations questionnaire (MBSRQ). Subgroups of the patients with CD were formed on the basis of remission status and BDI scores. In this study, QoL in the general health category and body image were lower in the patients with CD than in the healthy subjects. However, no differences in depression scores were found between the two groups. When the CD group was evaluated according to remission rate, the mean BDI score was significantly higher in the CD patients without remission than in both the CD patients with remission and the healthy subjects (p = 0.04). However, the physical functioning, bodily pain and general health scores of the CD patients without remission on the SF-36 questionnaire were lower than in the CD patients in remission and the healthy subjects (p = 0.002, p = 0.04, p = 0.002, respectively). Fitness evaluation, health evaluation and body areas satisfaction scores of the MBSRQ were significantly different in the three groups (p = 0.003, p = 0.009 and p = 0.001, respectively). In this study, patients with CD were found to have lower QoL, lower body image perception and higher levels of depression compared to healthy controls, particularly if the disease is persistant despite surgery.

This study aimed to evaluate patient-reported outcomes as well as lower extremity and trunk muscle function in patients with long-standing hip and groin pain, in comparison with matched, healthy controls. It was hypothesized that patients with long-standing hip and groin pain would report more deficiency on the Copenhagen Hip and Groin Outcome Score (HAGOS) and have worse outcomes on performance-based measures than healthy controls. Nineteen patients with long-standing hip and groin pain and 19 healthy, activity level-, age-, gender-, and weight-matched controls were assessed with the HAGOS for self-reported outcomes, and a parallel squat (w/kg), single-leg triple jump (cm), single-leg rise (n), barbell roll-out (% of height), and plank test (s) for performance-based measures. Independent sample t test was performed to assess between-group differences. The paired t test was used to analyse between-limb differences in unilateral performance tasks. The patients had worse scores than the controls in all HAGOS subscales (p ≤ 0.001), while no statistically significant differences were observed for any performance measure between groups or between symptomatic and non-symptomatic limbs. Despite significant self-reported functional limitations on the HAGOS, there were no significant differences between groups in performance-based strength or power measures. The results of this study highlight the need to identify performance-based measures, sensitive to functional deficiencies in patients with long-standing hip and groin pain in order to complement the clinical picture obtained by patient-reported outcomes such as the HAGOS.

The aim of this study was to investigate the magnitude of association of the severity of temporomandibular disorders (TMDs) in women with episodic and chronic migraine. Thirty-one women with episodic migraine (mean age: 33 years), 21 with chronic migraine (mean age: 35 years) and 32 healthy controls (mean age: 31 years) were included. The Fonseca Anamnestic Index was applied to assess severity of TMDs. TMD severity was considered as follows: no TMD (0-19 points), mild TMD (20-49 points), moderate TMD (50-69 points), and severe TMD (70-100 points). To compare the proportion of TMD severity among groups, a χ 2 test was performed. Prevalence ratio (PR) was calculated to determine the association of TMD severity and both migraine groups using the control group as the reference. Women with chronic and episodic migraine were more likely to exhibit TMD signs and symptoms of any severity than healthy controls (χ 2 = 30.26; P < .001). TMD prevalence was 54% for healthy controls, 78% for episodic migraine, and 100% for chronic migraine. Women with chronic migraine exhibited greater risk of more severe manifestations of TMD than healthy controls (PR: 3.31; P = .008). This association was not identified for episodic migraine (PR: 2.18; P = .101). The presence of TMD signs and symptoms was associated with migraine independently of the frequency; however, the magnitude of the association of more severe TMD was significantly greater in chronic, but not episodic, migraine.

Heart rate and autonomic response to stress after experimental induction of worry versus relaxation in healthy, high-worry, and generalized anxiety disorder individuals.

PubMed

Fisher, Aaron J; Newman, Michelle G

2013-04-01

Generalized anxiety disorder (GAD) is the most commonly occurring anxiety disorder and has been related to cardiovascular morbidity such as cardiac ischemia, sudden cardiac death, and myocardial infarction. Both GAD and its cardinal symptom - worry - have been shown to promote muted physiological reactivity in response to laboratory and ecological stressors. Importantly, no study to date has examined the concurrent and relative contributions of trait and state worry within healthy controls, (non-clinical) high trait-worry controls, and GAD participants. The present study examined heart rate (HR), respiratory sinus arrhythmia (RSA), and salivary alpha-amylase (sAA) responses to laboratory stress during and following the experimental induction of worry versus relaxation in healthy controls (n=42), high trait worriers (n=33) and participants with GAD (n=76). All groups exhibited increased HR and decreased RSA in response to the stressor, with no differences by condition. Baseline sAA significantly moderated HR and RSA reactivity, such that higher sAA predicted greater increases in HR and decreases in RSA. There was a significant group by baseline sAA interaction such that in GAD, higher baseline sAA predicted decreased change in sAA during stress, whereas higher baseline sAA predicted greater sAA change in healthy controls. High-worry controls fell non-significantly between these groups. The present study provides additional evidence for the effect of worry on diminished HR stress response and points to possible suppression of adrenergic sympathetic stress responses in GAD.

Garand, K L; Schwertner, Ryan; Chen, Amy; Pearson, William G

2018-04-01

Swallowing impairment (dysphagia) is a common sequela in patients with motor neuron disease (MND). The purpose of this retrospective, observational pilot investigation was to characterize how pharyngeal swallowing mechanics are impacted in patients with MND using a comparison with healthy, non-dysphagic control group. Computational analysis of swallowing mechanics (CASM) was used to determine covariate biomechanics of pharyngeal swallowing from videofluoroscopic assessment in 15 patients with MND and 15 age- and sex-matched healthy controls. Canonical variant analysis with post hoc discriminate function analysis (DFA) was performed on coordinate data mapping functional muscle groups underlying pharyngeal swallowing. Differences in swallowing mechanics associated with group (MND; control), motor neuron predominance (upper; lower), onset (bulbar; spinal), and swallow task (thin, pudding) were evaluated and visualized. Pharyngeal swallowing mechanics differed significantly in patients with MND compared with healthy controls (D = 2.01, p < 0.0001). Post hoc DFA pairwise comparisons suggest differences in pharyngeal swallow mechanics by motor neuron predominance (D = 5.03, p < 0.0001), onset (D = 2.03, p < 0.0001), and swallow task (D = 1.04, p < 0.0001). Pharyngeal swallowing mechanics of patients with MND differ from and are more heterogeneous than healthy controls. These findings suggest patients with MND may compensate reductions in pharyngeal shortening and tongue base retraction by extending the head and neck and increasing hyolaryngeal excursion. This work and further CASM investigations will lead to further insights into development and evaluation of targeted clinical treatments designed to prolong safe and efficient swallowing function in patients with MND.

To determine whether patients with a painful myofascial temporomandibular disorder (TMD) have diminished nocturnal heart rate variability (HRV), a marker of autonomic nervous system (ANS) dysfunction, relative to healthy, pain-free controls. Participants with myofascial TMD and healthy, pain-free volunteers underwent nocturnal polysomnography studies during which HRV indices were measured. Multiple linear regression analyses were used to determine whether TMD status exerted unique effects on HRV. Ninety-five participants (n = 37 TMD; n = 58 controls) were included in the analyses. The TMD group had a lower standard deviation of R-R intervals (89.81 ± 23.54 ms versus 107.93 ± 34.42 ms, P ⋜ .01), a lower root mean squared successive difference (RMSSD) of R-R intervals (54.78 ± 27.37 ms versus 81.88 ± 46.43 ms, P < .01), and a lower high frequency spectral power (2336.89 ± 1224.64 ms² versus 2861.78 ± 1319 ms², P = .05) than the control group. The ratio of the low-frequency (LF) to the high-frequency (HF) spectral power was higher in the TMD group (2.47 ± 2 versus 1.38 ± 0.65, P < .01). The differences in RMSSD (91.21 ms versus 112.03 ms, P = .05) and LF:HF ratio (0.71 versus 0.32, P < .01) remained significant after controlling for age and psychological distress. Myofascial TMD patients revealed lower nocturnal HRV than healthy, pain-free controls. Further research should focus on processes that address this ANS imbalance, which may potentially lead to effective therapeutic interventions.

To identify the single leg balance (SLB) test that discriminates among healthy, coper, and chronic ankle instability (CAI) groups and to determine effects of ankle muscles on the balance error scoring system (BESS) among the three populations. 60 subjects (20 per group) performed the SLB test with eyes open (EO) and eyes closed (EC). Normalized mean amplitude (NMA) of the tibia anterior (TA), fibularis longus (FL), and medial gastrocnemius (MG) muscles and BESS were measured while performing the SLB test. The coper group had a lower error score than the CAI group in the EC. NMA was greater in the CAI group compared to in the healthy and coper groups regardless of muscle type. NMA of the TA was less than the PL and MG regardless of the group in the EO. The CAI group demonstrated greater NMAs of the PL and MG than the healthy and coper groups in the EC. The CAI group demonstrated greater NMA of the PL and MG by compensating their ankle muscles in the EO and EC. BESS suggests that the coper group may have coping mechanisms to stabilize static postural control compared to the CAI group. The EC may be better to detect static postural instability in the CAI or coper group. © Georg Thieme Verlag KG Stuttgart · New York.

Objective Small food store interventions show promise to increase healthy food access in under-resourced areas. However, none have tested the impact of price discounts on healthy food supply and demand. We tested the impact of store-directed price discounts and communications strategies, separately and combined, on the stocking, sales and prices of healthier foods and on storeowner psychosocial factors. Design Factorial design randomized controlled trial. Setting Twenty-four corner stores in low-income neighbourhoods of Baltimore City, MD, USA. Subjects Stores were randomized to pricing intervention, communications intervention, combined pricing and communications intervention, or control. Stores that received the pricing intervention were given a 10–30% price discount by wholesalers on selected healthier food items during the 6-month trial. Communications stores received visual and interactive materials to promote healthy items, including signage, taste tests and refrigerators. Results All interventions showed significantly increased stock of promoted foods υ. control. There was a significant treatment effect for daily unit sales of healthy snacks (β = 6·4, 95% CI 0·9, 11·9) and prices of healthy staple foods (β = −0·49, 95% CI −0·90, −0·03) for the combined group υ. control, but not for other intervention groups. There were no significant intervention effects on storeowner psychosocial factors. Conclusions All interventions led to increased stock of healthier foods. The combined intervention was effective in increasing sales of healthier snacks, even though discounts on snacks were not passed to the consumer. Experimental research in small stores is needed to understand the mechanisms by which store-directed price promotions can increase healthy food supply and demand. PMID:28222818

Among the long-term unemployed ill health is often a hindrance to successful reintegration in the job market. In a quasi-experimental controlled study we examined the effects of a health promotion intervention program tailored to the specific needs of the long-term unemployed combining individual sessions based on motivational interviewing and participatory group sessions including physical activity. Over a period of 3 months the participants of the intervention group (n = 179) showed more improvement compared to the control group (n = 108) in terms of motivation for lifestyle changes towards more physical activity and healthier nutrition. Participants of the intervention group developed an intention to act significantly more often (active lifestyle: odds ratio 4.44; 95% CI: 2.00-9.83; healthy nutrition: odds ratio 3.94; 95% CI: 1.55-10.00) and actually implemented a behavior change significantly more often (active lifestyle: odds ratio 2.77; 95% CI: 1.35-5.71; healthy nutrition: odds ratio 4.34; 95% CI: 1.92-9.78). In terms of smoking and alcohol consumption no significant intervention effects were detected. The results of the study show the effectiveness of the described health promotion program regarding a lifestyle change towards more healthy nutrition and more physical activity.

Background After adrenalectomy, urinary fractionated metanephrine concentrations are expected to be reduced. However, there are few studies suggesting cut-offs for adrenalectomy patients. Methods Urinary metanephrine and normetanephrine concentrations in adrenalectomy patients and two controls were compared and hormonal concentrations were evaluated via time intervals after surgery. Results The median urinary metanephrine level after unilateral adrenalectomy was lower than that of the non-pheochromocytoma controls but comparable to healthy controls. Urinary normetanephrine concentrations did not differ between adrenalectomy patients and non-pheochromocytoma controls, although both group had levels higher than those of healthy controls. The median urinary normetanephrine level in the immediate postoperative period was higher than in the later period. Conclusions Urinary metanephrine concentrations were lower after adrenalectomy, but urinary normetanephrine concentrations were not changed compared with the non-pheochromocytoma controls. However, urinary normetanephrine concentrations in the patient group were higher than levels in the heathy controls.

Coping with stress in adolescents with Type 1 diabetes and their mothers

Objectives Coping with stress plays a vital role in the adjustment of adolescents with diabetes. The majority of studies in this area leave out the control group, limiting their power to make inferences about specificity vs. similarity of coping strategies used by these adolescents. The aims of this study were: (1) To compare coping strategies in adolescents with diabetes and healthy adolescents; (2) To compare coping strategies in girls and boys with diabetes; (3) To determine whether there is a relationship between adolescents' coping strategies and their mothers' coping styles. Material and methods Adolescents (12-17 years old) with Type 1 diabetes (n = 51) were compared with a control group of healthy secondary school students (n = 56) by means of a self-reported questionnaire measuring coping strategies (Adolescence Coping Checklist). Mothers of these adolescents (n = 107) completed the Coping Inventory for Stressful Situations, measuring 3 coping styles. Results Diabetic adolescents used the 'seek professional help' strategy more often than their healthy peers. The girls with diabetes reported using the 'investing in close friends' strategy more often than boys, while in the control group girls were also more likely to use 'seeking social support', 'seeking spiritual support', and 'relaxing diversions' strategies. Mothers' emotion-oriented coping style predicted focus-oriented coping in adolescents with diabetes. In the non-diabetic group, mothers' task-oriented coping predicted seeking professional help, while mothers' avoidance-oriented coping predicted seeking spiritual support. Conclusions The results demonstrated that: (1) the only differences in terms of coping strategies in adolescents with diabetes and healthy adolescents were found in seeking professional help; (2) gender differences in coping with stress were significantly smaller in adolescents with diabetes than in healthy adolescents, (3) mothers' coping styles were predictors of coping strategies in adolescents, albeit there were differences in that respect between adolescents with diabetes and healthy adolescents.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder affecting children and adults. Previous studies found that functional near-infrared spectroscopy (fNIRS) can reveal significant group differences in several brain regions between ADHD children and healthy controls during working memory tasks. This study aimed to use fNIRS activation patterns to identify ADHD children from healthy controls. FNIRS signals from 25 ADHD children and 25 healthy controls performing the n-back task were recorded; then, multivariate pattern analysis was used to discriminate ADHD individuals from healthy controls, and classification performance was evaluated for significance by the permutation test. The results showed that 86.0% ([Formula: see text]) of participants can be correctly classified in leave-one-out cross-validation. The most discriminative brain regions included the bilateral dorsolateral prefrontal cortex, inferior medial prefrontal cortex, right posterior prefrontal cortex, and right temporal cortex. This study demonstrated that, in a small sample, multivariate pattern analysis can effectively identify ADHD children from healthy controls based on fNIRS signals, which argues for the potential utility of fNIRS in future assessments.

AIM To define regional grey-matter abnormalities in schizophrenia patients with poor insight (Insight-), relative to patients with preserved clinical insight (Insight+), and healthy controls. METHODS Forty stable schizophrenia outpatients (20 Insight- and 20 Insight+) and 20 healthy controls underwent whole brain magnetic resonance imaging (MRI). Insight in all patients was assessed using the Birchwood Insight Scale (BIS; a self-report measure). The two patient groups were pre-selected to match on most clinical and demographic parameters but, by design, they had markedly distinct BIS scores. Voxel-based morphometry employed in SPM8 was used to examine group differences in grey matter volumes across the whole brain. RESULTS The three participant groups were comparable in age [F(2,57) = 0.34, P = 0.71] and the patient groups did not differ in age at illness onset [t(38) = 0.87, P = 0.39]. Insight- and Insight+ patient groups also did not differ in symptoms on the Positive and Negative Syndromes scale (PANSS): Positive symptoms [t(38) = 0.58, P = 0.57], negative symptoms [t(38) = 0.61, P = 0.55], general psychopathology [t(38) = 1.30, P = 0.20] and total PANSS scores [t(38) = 0.21, P = 0.84]. The two patient groups, as expected, varied significantly in the level of BIS-assessed insight [t(38) = 12.11, P < 0.001]. MRI results revealed lower fronto-temporal, parahippocampal, occipital and cerebellar grey matter volumes in Insight- patients, relative to Insight+ patients and healthy controls (for all clusters, family-wise error corrected P < 0.05). Insight+ patient and healthy controls did not differ significantly (P > 0.20) from each other. CONCLUSION Our findings demonstrate a clear association between poor clinical insight and smaller fronto-temporal, occipital and cerebellar grey matter volumes in stable long-term schizophrenia patients.

To evaluate the immediate post-intervention and 6-month post-intervention effects of a Brazilian school-based randomized controlled trial for girls targeting shared risk factors for obesity and disordered eating. Total of 253 girls, mean of 15.6 (0.05) years from 1st to 3rd grades of high school participated in this 6-month school-based cluster randomized controlled trial. "Healthy Habits, Healthy Girls-Brazil (H3G-Brazil)", originally developed in Australia, emphasized 10 key nutrition and physical activity (PA) messages delivered over 6 months. Disordered eating prevention procedures, i.e., prevention of weight-teasing, body satisfaction, and unhealthy weight control behavior, were added to the intervention. Body dissatisfaction, unhealthy weight control behaviors and social cognitive-related diet, and physical activity variables were assessed at baseline, immediate post-intervention, and 6-month post-intervention. Intervention effects were determined by one-way analysis of covariance or logistic regression, after checking for the clustering effects of school. The control group did not receive intervention prior to follow-up assessment. A conservative significance level was set at p < 0.01. Beneficial effects were detected for PA social support (F = 6.005, p = 0.01), and healthy eating strategies (F = 6.08, p = 0.01) immediate post-intervention; and healthy eating social support (F = 14.731, p = 0.00) and healthy eating strategies (F = 5.812, p = 0.01) at 6-month post-intervention. Intervention group was more likely to report unhealthy weight control behaviors (OR = 1.92, 95% CI 1.15-3.21, p = 0.01) at 6-month post-intervention. No other significant immediate or 6-month post effects were detected. H3G-Brazil demonstrated positive 6-month effects on some social cognitive variables but an adverse effect on unhealthy weight control behaviors. Thus, this study was not able to achieve synergy by combining obesity and disordered eating prevention procedures in an intervention among low-income girls in Brazil. Level I: cluster randomized controlled trial.

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects social, communication, and behavioral development. Recent evidence supported but also questioned the hypothetical role of compounds containing mercury (Hg) as contributors to the development of ASD. Specific alterations in the urinary excretion of porphyrin-containing ring catabolites have been associated with exposure to Hg in ASD patients. In the present study, the level of urinary porphyrins, as biomarkers of Hg toxicity in children with ASD, was evaluated, and its correlation with severity of the autistic behavior further explored. A total of 100 children was enrolled in the present study. They were classified into three groups: children with ASD (40), healthy controls (40), and healthy siblings of the ASD children (20). Children with ASD were diagnosed using DSM-IV-TR, ADI-R, and CARS tests. Urinary porphyrins were evaluated within the three groups using high-performance liquid chromatography (HPLC), after plasma evaluation of mercury (Hg) and lead (Pb) in the same groups. Results showed that children with ASD had significantly higher levels of Hg, Pb, and the porphyrins pentacarboxyporphyrin, coproporphyrin, precoproporphyrin, uroporphyrins, and hexacarboxyporphyrin compared to healthy controls and healthy siblings of the ASD children. However, there was no significant statistical difference in the level of heptacarboxyporphyrin among the three groups, while a significant positive correlation between the levels of coproporphyrin and precoproporphyrin and autism severity was observed. Mothers of ASD children showed a higher percentage of dental amalgam restorations compared to the mothers of healthy controls suggesting that high Hg levels in children with ASD may relate to the increased exposure to Hg from maternal dental amalgam during pregnancy and lactation. The results showed that the ASD children in the present study had increased blood Hg and Pb levels compared with healthy control children indicating that disordered porphyrin metabolism might interfere with the pathology associated with the autistic neurologic phenotype. The present study indicates that coproporphyrin and precoproporhyrin may be utilized as possible biomarkers for heavy metal exposure and autism severity in children with ASD.

Ninety-two healthy pregnant women. The intervention was administered during gestational weeks 14-25. The intervention group received supervised resistance exercise twice a week, performed at an activity level equivalent to within moderate-to-vigorous (n = 51). The control group received generalized exercise recommendation, a home-based training program and a telephone follow up (n = 41). Health-related quality of life, physical strength, pain, weight, blood pressure, functional status, activity level, and perinatal data. Functional status deteriorated during the intervention in both groups and pain increased. Significant differences between the groups were obtained only for birthweight. Newborns delivered by women who underwent resistance exercise during pregnancy were significantly heavier than those born to control women; 3561 (±452) g vs. 3251 (±437) g (p = 0.02), a difference that disappeared when adjustment was made for gestational age (p = 0.059). Both groups showed normal health-related quality of life, blood pressure, and perinatal data. These findings indicate that supervised, moderate-to-vigorous resistance exercise does not jeopardize the health status of healthy pregnant women or the fetus during pregnancy, but instead appears to be an appropriate form of exercise in healthy pregnancy. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

Objective To study resting cerebral blood flow in children and adults with developmental stuttering. Methods We acquired pulsed arterial spin labeling magnetic resonance imaging data in 26 participants with stuttering and 36 healthy, fluent controls. While covarying for age, sex, and IQ, we compared perfusion values voxel-wise across diagnostic groups and assessed correlations of perfusion with stuttering severity within the stuttering group and with measures of motor speed in both groups. Results We detected lower regional Cerebral Blood Flow (rCBF) at rest in the stuttering group compared to healthy controls in Broca’s area bilaterally and the superior frontal gyrus. rCBF values in Broca’s area bilaterally correlated inversely with the severity of stuttering and extended posteriorly into other portions of the language loop. We also found increased rCBF in cerebellar nuclei and parietal cortex in the stuttering group compared to healthy controls. Findings were unchanged in child-only analyses and when excluding participants with comorbid illnesses or those taking medication. Conclusions rCBF is reduced in Broca’s region in persons who stutter. More severe stuttering is associated with even greater reductions in rCBF to Broca’s region, additive to the underlying putative trait reduction in rCBF relative to control values. Moreover, a greater abnormality in rCBF in the posterior language loop is associated with more severe symptoms, suggesting that a common pathophysiology throughout the language loop likely contributes to stuttering severity.

The goal of this study was to create a guide for programs considering transition from Lead Poisoning Prevention to Healthy Homes. Healthy Homes programs are comprehensive, focusing on multiple residential housing hazards. This study focused on the Baltimore City Healthy Homes Division, which was selected by the Centers for Disease Control and Prevention to pilot the transition process. For this qualitative study, data were collected through interviews with program staff from the Baltimore City Healthy Homes Division and followed up by focus groups with community members who received its services. Grounded theory procedures were used for data analysis. Interviews and focus groups were conducted in Baltimore City near the Health Department. Seventeen interviews were conducted with Baltimore City Healthy Homes Division staff. Three focus groups were held with 3 to 6 community participants in each group. Findings for the study are arranged around an organizational framework for which transition from Lead Poisoning Prevention to Healthy Homes is the central phenomenon. Three general themes emerged: (1) programmatic changes; (2) policy changes; and (3) partnerships. Quotations from participating staff and community members provide supporting evidence for the results. Findings provide insight into the strengths and challenges of transition for 1 program. The study has implications for change on a national level as programs around the country transition to provide families with comprehensive Healthy Homes services.

Background Physical exercise influences homocysteine (Hcy) concentrations, cognitive function and the metabolic profile. The purpose of this study was to investigate the influence of regular physical exercise on Hcy levels, the metabolic profile and cognitive function in healthy elderly males before and after an endurance exercise program. Methods Forty-five healthy and sedentary volunteers were randomized into 2 groups: (1) a control group asked not to change their normal everyday activities and not to start any regular physical exercise program and (2) an experimental group trained at a heart rate intensity corresponding to ventilatory threshold 1 (VT-1) for 60 min/day 3 times weekly on alternate days for 6 months using a cycle ergometer. All volunteers underwent cognitive evaluations, blood sample analyses and ergospirometric assessments. Results A significant improvement in cognitive function was observed in the experimental group compared with the control group (p < 0.05). No significant changes in Hcy levels were observed in the experimental group (p > 0.05), but there was a significant increase in peak oxygen consumption and workload at VT-1 as well as a significant improvement in cholesterol, triglycerides, HDL, glucose, alkaline phosphatase, urea, T3, T4 and prostate-specific antigen compared with the control group (p < 0.05). Conclusion The data suggest that a physical exercise program does not reduce Hcy levels in healthy elderly males, although it improves the cardiovascular and metabolic profile as well as cognitive function.

Female patients with schizophrenia are less impaired in social life than male patients. Because social impairment in schizophrenia has been found to be associated with deficits in emotion recognition, we examined whether the female advantage in processing emotional prosody and semantics is preserved in schizophrenia. Forty-eight patients (25 males, 23 females) and 46 controls (23 males, 23 females) were assessed using an emotional language task (in which healthy women generally outperform healthy men), consisting of 96 sentences in four conditions: (1) neutral-content/emotional-tone (happy, sad, angry or anxious); (2) neutral-tone/emotional-content; (3) emotional-tone/incongruous emotional-content; and (4) emotional-content/incongruous emotional-tone. Participants had to ignore the emotional-content in the third condition and the emotional-tone in the fourth condition. In addition, participants were assessed with a visuospatial task (in which healthy men typically excel). Correlation coefficients were computed for associations between emotional language data, visuospatial data, IQ measures and patient variables. Overall, on the emotional language task, patients made more errors than control subjects, and women outperformed men across diagnostic groups. Controlling for IQ revealed a significant effect on task performance in all groups, especially in the incongruent tasks. On the rotation task, healthy men outperformed healthy women, but male patients, female patients and female controls obtained similar scores. The advantage in emotional prosodic and semantic processing in healthy women is preserved in schizophrenia, whereas the male advantage in visuospatial processing is lost. These findings may explain, in part, why social functioning is less compromised in women with schizophrenia than in men.

BAG3 is a member of human BAG (Bcl-2-associated athanogene) proteins and plays a role in apoptosis, cell adhesion, cytoskeleton remodeling, and autophagy. The aim of this study was to evaluate BAG3 levels in healthy subjects, hypertensive patients, and hypertensive diabetic patients. We enrolled 209 Caucasian adults, of both sex, 18-75 years of age, 77 were healthy controls, 62 were affected by hypertension, and 70 were affected by hypertension and type 2 diabetes. All patients underwent an assessment that included medical history, physical examination, vital signs, a 12-lead electrocardiogram, measurements of systolic (SBP), and diastolic blood pressure (DBP), heart rate (HR), fasting plasma glucose (FPG), glycated hemoglobin (HbA 1c ), triglycerides (TG), transaminases, high sensitivity C-reactive protein (Hs-CRP), and BAG3. We observed higher blood pressure values in hypertensive, and hypertensive diabetic patients compared to controls. As expected, FPG and HbA 1c were higher in diabetic hypertensive patients, compared to the other two groups. No Tg levels differences were recorded among the three groups. Hs-CRP was higher in diabetic hypertensive patients compared to healthy subjects. Finally, BAG3 levels were higher in hypertensives, and hypertensive diabetic patients compared to controls. We observed higher levels of BAG3 in hypertensive patients compared to healthy controls, and even higher levels in hypertensive diabetic patients compared to healthy subjects. This paper could be the first of a long way to identify potential involvement of deregulated BAG3 levels in cardiometabolic diseases. © 2017 Wiley Periodicals, Inc.

The objective of this article was to examine lifestyle behaviours in eating disorder (ED) patients and healthy controls. A total of 801 ED patients and 727 healthy controls from five European countries completed the questions related to lifestyle behaviours of the Cross-Cultural Questionnaire (CCQ). For children, the ED sample exhibited more solitary activities (rigorously doing homework [p<0.001] and watching TV [p<0.05] and less socializing with friends [p<0.05]) than the healthy control group and this continued in adulthood. There were minimal differences across ED sub-diagnoses and various cross-cultural differences emerged. Reduced social activities may be an important risk and maintaining factor for ED symptomatology.

Purpose The purpose of the study was to explore and understand knowledge and attitudes about food, diet, and weight control, focusing on barriers and motivators to reduce risk of developing type 2 diabetes. Methods Six focus groups were conducted in May and June 2010. The groups were stratified by sex. A total of 35 ethnically diverse samples with a high risk for type 2 diabetes participated. The average age was 51 ± 10.6 years, and 57% of the sample represented women. Results Four themes emerged from the focus groups: (1) demonstrated knowledge and source of knowledge, including participants’ basic understanding of “good” and “bad” food and what constitutes a “healthy diet” and trusted sources of information; (2) perceptions of food and diet, encompassing how participants expressed their perception of and interaction with food and diet; (3) sense of control over dietary intake, reflecting participants’ discussion of their perceived ability to control their eating patterns and food choices; and (4) eating behaviors, describing participants’ patterns of eating and perceived barriers to eating a healthy diet. Conclusions Study findings demonstrate that eating healthy requires a complex interaction between individual perceptions of food and sense of control over eating patterns and socio-political and economic structural factors that restrict healthy eating options while promoting unhealthy ones. Programs for long-term eating behavioral change necessary to reduce type 2 diabetes and obesity need to incorporate strategies that address individual-level factors of perception of food and sense of control over eating patterns, as well as structural level factors such as poverty and food insecurity.

Profiling volatile organic compounds in exhaled breath enables the diagnosis of several types of cancer. In this study we investigated whether a portable point-of-care version of an electronic nose (e-nose) (Aeonose, [eNose Company, Zutphen, the Netherlands]) is able to discriminate between patients with lung cancer and healthy controls on the basis of their volatile organic compound pattern. In this study, we used five e-nose devices to collect breath samples from patients with lung cancer and healthy controls. A total of 60 patients with lung cancer and 107 controls exhaled through an e-nose for 5 minutes. Patients were assigned either to a training group for building an artificial neural network model or to a blinded control group for validating this model. For differentiating patients with lung cancer from healthy controls, the results showed a diagnostic accuracy of 83% with a sensitivity of 83%, specificity of 84%, and area under the curve of 0.84. Results for the blinded group showed comparable results, with a sensitivity of 88%, specificity of 86%, and diagnostic accuracy of 86%. This feasibility study showed that this portable e-nose can properly differentiate between patients with lung cancer and healthy controls. This result could have important implications for future lung cancer screening. Further studies with larger cohorts, including also more participants with early-stage tumors, should be performed to increase the robustness of this noninvasive diagnostic tool and to determine its added value in the diagnostic chain for lung cancer.

Several case-control studies have shown associations between the risk of different cancers and self-reported opium use. Inquiring into relatively sensitive issues, such as the history of drug use, is usually prone to information bias. However, in order to justify the findings of these types of studies, we have to quantify the level of such a negative bias. In current study, we aimed to evaluate sensitivity of self-reported opioid use and suggest suitable types of control groups for case-control studies on opioid use and the risk of cancer. In order to compare the validity of the self-reported opioid use, we cross-validated the response of two groups of subjects 1) 178 hospitalized patients and 2) 186 healthy individuals with the results of their tests using urine rapid drug screen (URDS) and thin layer chromatography (TLC). The questioners were asked by trained interviewers to maximize the validity of responses; healthy individuals were selected from the companions of patients in hospitals. Self-reported regular opioid use was 36.5% in hospitalized patients 19.3% in healthy individuals (p-value> 0.001).The reported frequencies of opioid use in the past 72 hours were 21.4% and 11.8% in hospitalized patients and healthy individuals respectively. Comparing their responses with the results of urine tests showed a sensitivity of 77% and 69% among hospitalized patients and healthy individuals for self-reports (p-value = 0.4). Having corrected based on the mentioned sensitivities; the frequency of opioid regular use was 47% and 28% in hospitalized patients and healthy individuals, respectively. Regular opioid use among hospitalized patients was significantly higher than in healthy individuals (p-value> 0.001). Our findings showed that the level of opioid use under-reporting in hospitalized patients and healthy individuals was considerable but comparable. In addition, the frequency of regular opioid use among hospitalized patients was significantly higher than that in the general population. Altogether, it seems that, without corrections for these differences and biases, the results of many studies including case-control studies on opioid use might distort findings substantially.

Objective  The objective of this study was to evaluate the correlation between fitness and health-related quality of life (HRQoL) in children with idiopathic epilepsy compared with a healthy matched control group. Methods  In this study, 107 children conducted a 6-minute walk test, anthropometric parameters were measured, and HRQoL was assessed using a standardized questionnaire (KINDL-R). Children were divided into two groups: (1) the patient group ( n  = 48) and (2) the healthy control group ( n  = 59). Results  HRQoL of children with focal epilepsy was greater when compared with healthy children and children with generalized epilepsy. A significant association could be demonstrated for the 6-minute walk distance and mental wellbeing in children with epilepsy but not in healthy children. Furthermore, a negative correlation between the HRQoL and the amount of time spent in front of TV and computer in children with epilepsy and healthy children was seen. In children with focal epilepsy, a significant negative correlation could be shown between school sport and mental wellbeing as well as between school sport and self-esteem. Conclusion  HRQoL in children with idiopathic epilepsy is significantly associated with physical fitness and might be positively influenced by an adequate education of patients and parents, a reduction of consumption of computer and TV in combination with age- and disease-adapted physical activity and sports.

The aim of this study was to investigate the possible alterations in postural control during upright standing in subjects with non-specific chronic low back pain and the effect of Kinesio taping on the postural control. Twenty subjects with non-specific chronic low back pain and twenty healthy subjects participated in this study. The center of pressure excursion was evaluated before the intervention for both groups, and immediately after intervention for the low back pain group. Independent sample t-test, Mann-Whitney test and repeated measure ANOVA were used for the statistical analysis of the data. There were significant differences in the center of pressure excursion between the low back pain group versus the healthy group. The results of the ANOVA demonstrated a statistically significant difference in the mean COP displacement and velocity before Kinesio Taping, immediately after, and 24 h after in the low back pain group. There are poor postural control mechanisms in subjects with non-specific chronic low back pain. Kinesio taping seems to change postural control immediately and have lasting effects until the day after. Copyright © 2017 Elsevier Ltd. All rights reserved.

Motor imagery is used for treatment of motor deficits after stroke. Clinical observations suggested that motor imagery abilities might be reduced in patients with severe sensory deficits. This study investigated the influence of somatosensory deficits on temporal (mental chronometry, MC) and spatial aspects of motor imagery abilities. Stroke patients (n = 70; <6 months after stroke) were subdivided into 3 groups according to their somatosensory functions. Group 1 (n = 31) had no sensory deficits, group 2 (n = 27) had a mild to moderate sensory impairment and group 3 (n = 12) had severe sensory deficits. Patients and a healthy age-matched control group (n = 23) participated in a mental chronometry task (Box and Block Test, BBT) and a mental rotation task (Hand Identification Test, HIT). MC abilities were expressed as a ratio (motor execution time-motor imagery time/motor execution time). MC for the affected hand was significantly impaired in group 3 in comparison to stroke patients of group 1 (p = 0.006), group 2 (p = 0.005) and healthy controls (p < 0.001). For the non-affected hand MC was similar across all groups. Stroke patients had a slower BBT motor execution than healthy controls (p < 0.001), and group 1 executed the task faster than group 3 (p = 0.002). The percentage of correct responses in the HIT was similar for all groups. Severe sensory deficits impair mental chronometry abilities but have no impact on mental rotation abilities. Future studies should explore whether the presence of severe sensory deficits in stroke patients reduces the benefit from motor imagery therapy.

Early diagnosis and treatment of cardiovascular diseases, the most frequent cause of morbidity and mortality in acromegaly, may be an efficient approach to extending the lifespan of affected patients. Therefore, it is crucial to determine any cardiovascular diseases in the subclinical period. The study objectives were to determine markers of subclinical atherosclerosis and asses heart structure and function. This was a cross-sectional, single-center study of 53 patients with acromegaly and 22 age- and sex-matched healthy individuals. Carotid intima-media thickness (CIMT), pulse-wave velocity (PWV), and echocardiographic data were compared between these groups. CIMT and PWV were higher in the acromegaly group than in the healthy group (P = .008 and P = .002, respectively). Echocardiography showed that left ventricular diastolic dysfunction was present in 11.3% of patients. Left ventricular mass index and left atrial volume index were higher in the patients (P = .016 and P<.001, respectively). No differences in the CIMT, PWV, or echocardiographic measurements were identified between the patients with biochemically controlled and uncontrolled acromegaly and the control group. Our results showed that subclinical atherosclerosis (i.e., CIMT and PWV markers) and heart structure and function were worse in patients with acromegaly than in healthy individuals. Because there were no differences in these parameters between patients with controlled and uncontrolled acromegaly, our results suggest that the structural and functional changes do not reverse with biochemical control.

Increasing burden of overweight and obesity among young adults is mainly due to unhealthy lifestyle especially with respect to diet and physical activity. At the same time, younger generations are spending more time with social network sites. Therefore, this study was intended to explore the role of social networking sites in promoting healthy lifestyle. To measure the efficacy of health education using social networking sites in promoting healthy lifestyle among medical students in Puducherry, India. A non-randomized controlled trial was conducted in a private medical college located in Puducherry. The study participants were overweight/obese individuals with (intervention arm) and without Facebook account (control arm). Following a baseline survey, both the groups received health education from dietician and physical trainer using Audiovisual (AV) aids. Intervention group received health education through Facebook in the forms of messages, pictures and videos for six weeks. Then, follow up survey was done to assess the change in dietary pattern, physical activity and body weight. Data of those who attended baseline, intervention and follow up surveys (23- control and 22- intervention) were analysed. Means and proportions were calculated. Paired t-test and Chi-square test were used to calculate the p-value. The p-value<0.05 was considered as statistically significant. Mean number of days of junk food intake per week was reduced in both control and intervention groups from 2.91 days/week and 3.27 days/week at baseline to 2.65 days/week to two days/week at follow up respectively. A significant decrease in the Body Mass Index (BMI) (p<0.05) was found among the control group (baseline: 25.57, follow up: 25.15). No significant changes were found with respect to physical activity and intake of fruits and vegetables. Except for the decrease in junk food intake, use of Facebook as an effective tool to promote healthy lifestyle could not be proved with confidence.

This study was conducted to estimate and correlate salivary thiocyanate (SCN) levels in periodontally healthy subjects, smokers, nonsmokers, and gutka-chewers with chronic periodontitis. The study population consisted of 40 systemically healthy subjects in the age group of 18-55 years that was further divided into four groups: Control, smokers, nonsmokers, and gutka-chewers with chronic periodontitis. Gingival index (GI) (Loe and Silness-1963), probing depth (PD), clinical attachment loss was assessed. Estimation of SCN was performed by ultraviolet spectrophotometer at 447 nm wavelength. Statistical analysis was performed using the one-way ANOVAs Welch test and Pearson's correlation test using SPSS version 17 software. Results showed statistically significant increase in SCN levels in smokers as compared to gutka-chewers with chronic periodontitis, control, and nonsmokers with chronic periodontitis subjects. Significantly higher PD and loss of attachment were seen in smokers group compared with other groups. A negative correlation observed between the GI and thiocyanate levels. The present study revealed a significant increase in SCN levels in smokers with periodontitis as compared to nonsmokers.

The probability of developing osteoporosis decreases with an adequate supply of vitamin D, a balanced diet, and increased physical activity. In this study, we evaluated whether an educational intervention improves osteoporosis-related behavior in perimenopausal women from rural areas. A randomized experimental evaluation was performed of an educational intervention. The variables were physical activity, calcium intake and sun exposure in women from rural areas aged 45-54 years (n=216) at time 0 and 12 months after the educational intervention. In the control group (n=106), the information was sent by surface mail (month 0). In the intervention group (n=110), two interactive workshops were given (month 0). The topic of the workshops and the information sent by surface mail was healthy habits for osteoporosis prevention. After 12 months, the intervention group, but not the control group, had increased their physical activity (p=0.006), sun exposure (p=0.029), and calcium intake (53% to 64%). A simple educational intervention in perimenopausal women from rural areas improved healthy habits for osteoporosis prevention. Copyright © 2013 SESPAS. Published by Elsevier Espana.

To compare plasma N-terminal pro-atrial natriuretic peptide concentrations in preeclamptic patients and healthy normotensive pregnant women. A cases-controls study was done with 180 patients at Hospital Central Dr. Urquinaona, Maracaibo, Venezuela, that included 90 preeclamptic patients (group A; cases) and 90 healthy normotensive pregnant women selected with the same age and body mass index similar to group A (group B; controls). Blood samples were collected one hour after admission and prior to administration of any medication in group A to determine plasma N-terminal pro-atrial natriuretic peptide and other laboratory parameters. Plasma N-terminal pro-atrial natriuretic peptide concentrations in group A (mean 1.01 [0.26] pg/mL) showed a significant difference when compared with patients in group B (mean 0.55 [0.07] pg/mL; P<.001]. There was no significant correlation with systolic and diastolic blood pressure values in preeclamptic patients (P=ns). A cut-off value of 0.66ng/mL had an area under the curve of 0.93, sensitivity of 87.8%, specificity of 83.3%, a positive predictive value of 84.0% and a negative predictive value of 87.2%, with a diagnostic accuracy of 85.6%. Preeclamptic patients have significantly higher concentrations of plasma N-terminal pro-atrial natriuretic peptide compared with healthy normotensive pregnant women, with high predictive values for diagnosis.

The behavior of the circulating microparticles (cMP) in severe preeclampsia (PE) and fetal growth restriction (FGR) is disputed. METHOD OF STUDY  Non-matched case-control study. Seventy cases of severe PE/HELLP/FGR were compared to 38 healthy pregnant women. Twenty healthy non-pregnant women acted as a control. cMP were analyzed using flow cytometry. Results are given as total (annexin-A5-ANXA5+), platelet (CD41+), leukocyte (CD45+), endothelial (CD144+CD31+//CD41-), and CD41-negative cMP/μL of plasma. Antiphospholipid antibodies (aPL) were analyzed through usual methods. Platelet and endothelial cMP increased in healthy pregnant women. PE whole group (PE±FGR) showed an increase in endothelial and CD41-negative, but not in platelet-derived, cMP. Comparing PE whole group versus healthy pregnant, we found cMP levels of endothelial and CD41- had increased. The cMP results obtained in PE group were similar to those of the PE whole group. Comparing PE group to isolated FGR, significant CD41-negative cMP increase was found in PE. According to its aPL positivity, a trend to decrease in leukocyte and endothelial-derived cMP was found in PE group. Normal pregnancy is accompanied by endothelial and platelet cell activation. Endothelial cell activation has been shown in PE but not in isolated FGR. In PE, aPL may contribute to endothelial and possibly to leukocyte cell activation. © 2011 John Wiley & Sons A/S.

Supermarket Healthy Eating for Life (SHELf): protocol of a randomised controlled trial promoting healthy food and beverage consumption through price reduction and skill-building strategies

PubMed Central

2011-01-01

Background In the context of rising food prices, there is a need for evidence on the most effective approaches for promoting healthy eating. Individually-targeted behavioural interventions for increasing food-related skills show promise, but are unlikely to be effective in the absence of structural supports. Fiscal policies have been advocated as a means of promoting healthy eating and reducing obesity and nutrition-related disease, but there is little empirical evidence of their effectiveness. This paper describes the Supermarket Healthy Eating for LiFe (SHELf) study, a randomised controlled trial to investigate effectiveness and cost-effectiveness of a tailored skill-building intervention and a price reduction intervention, separately and in combination, against a control condition for promoting purchase and consumption of healthy foods and beverages in women from high and low socioeconomic groups. Methods/design SHELf comprises a randomised controlled trial design, with participants randomised to receive either (1) a skill-building intervention; (2) price reductions on fruits, vegetables and low-joule soft drink beverages and water; (3) a combination of skill-building and price reductions; or (4) a control condition. Five hundred women from high and low socioeconomic areas will be recruited through a store loyalty card program and local media. Randomisation will occur on receipt of informed consent and baseline questionnaire. An economic evaluation from a societal perspective using a cost-consequences approach will compare the costs and outcomes between intervention and control groups. Discussion This study will build on a pivotal partnership with a major national supermarket chain and the Heart Foundation to investigate the effectiveness of intervention strategies aimed at increasing women's purchasing and consumption of fruits and vegetables and decreased purchasing and consumption of sugar-sweetened beverages. It will be among the first internationally to examine the effects of two promising approaches - skill-building and price reductions - on diet amongst women.

2007-01-01

A number of recent scientific publications suggest that patients suffering from whiplash-associated disorders (WADs) exhibit sensorimotor deficits in the control of head and neck movements. The main objective of the present study was to evaluate if subjects with WADs can produce isometric neck extension and flexion forces with precision, variability, and a mode of control similar to the values of healthy subjects. A control group study with repeated measures. Neck force production parameters and neuromuscular control were measured in 17 whiplash and 14 control subjects. The experimental group included subjects who had a history of persistent neck pain or disability after a motor vehicle accident. Pain levels were assessed on a standard 100-mm visual analog pain scale at the beginning and end of the experiment. Each whiplash subject completed the neck disability index and the short-form 36 health survey (SF-36) questionnaire before the experiment. All subjects were asked to exert flexion and extension forces against a fixed head harness. Kinetic variables included time to peak force, time to peak force variability, peak force variability, and absolute error in peak force. Surface electrodes were applied bilaterally over the sternocleidomastoideus and paraspinal muscles. Electromyography (EMG)-dependent variables included EMG burst duration and amplitude using numerical integrated techniques. The average time to peak force was significantly longer for whiplash subjects than for the healthy controls. A significant increase in peak force variability was also observed in the whiplash group, and no group differences were noted for absolute error. Heightened muscular activity was seen in both paraspinal muscles, even though it only reached statistical significance for the left paraspinal muscle. Our results show that the whiplash subjects involved in the study were able to produce isometric forces with spatial precision similar to healthy controls using a motor strategy in which the time to peak force is increased. This trade-off between spatial precision and time to peak force probably reflects an adaptation aimed at limiting pain and further injuries.

In psychotic disorders, impairments in cognition have been associated with both clinical and functional outcome, while deficits in social cognition have been associated with functional outcome. As an extension to a recent report on neurocognition and short-term clinical outcome in first-episode psychosis (FEP), the current study explored whether social cognitive deficits could also identify poor short-term clinical outcome among FEP patients. We defined the social-cognition domain based on the scores from the Hinting Task and the Four Factor Tests of Social Intelligence. Data were collected in 45 FEP patients and 26 healthy controls. The patients were divided into good- and poor-outcome groups based on clinical data at six months following initiation of treatment. Social cognition was compared among 27 poor-outcome, 18 good-outcome, and 26 healthy-control participants. Outcome groups significantly differed in the social cognition domain (z-scores: poor outcome=-2.0 [SD=1.4]; good outcome=-1.0 [SD=1.0]; p=0.005), with both groups scoring significantly lower than the control group (p<0.003). Moreover, outcome groups differed significantly only on the Cartoon Predictions subtest (z-scores: poor outcome=-2.7 [SD=2.7]; good outcome=-0.7 [SD=1.8]; p=0.001) among the five subtests used. Overall, social cognition appears to be compromised in all FEP patients compared to healthy controls. More interestingly, significant differences in social cognitive impairments exist between good and poor short-term clinical outcome groups, with the largest effect found in the Cartoon Predictions subtest.

This was to examine healthy children and adolescents treated under general anaesthesia (GA) and a matched control group not receiving GA to compare treatment and preventive care received prior to GA treatment. This retrospective cohort study included 71 healthy subjects and 213 age- and gender-matched control subjects. The treatment group had been consecutively referred from the Public Dental Health Service (PDS) in Stockholm to the Department of Paediatric Dentistry, Eastman Institute, Stockholm during 2006-2007. Data was extracted from the patient records at the PDS, including variables such as number of dental visits, treatment/prophylaxis prior to GA, number of missed and cancelled appointments, and number of decayed teeth. On average, the treatment group had significantly more decayed teeth (p < 0.001) than the control group. Furthermore, the treatment group had significantly more restorations (p < 0.01), had visited the dentist significantly more often (p < 0.001), and had undergone significantly more behaviour management treatment and preventive treatment (p < 0.001). In the treatment group 65% of the children and adolescents, had received no behaviour management treatment and 48%, no preventive treatment. In the Stockholm PDS, over half of the children and adolescents referred by general dentists to paediatric specialists had no behaviour management treatment and nearly half, no preventive treatment, despite receiving significantly more operative treatment compared with matched controls. General dentists should target high caries-risk patients for additional behaviour management and preventive care to reduce the need for treatment under GA.

Variability in postural control with and without balance-based torso- weighting in people with multiple sclerosis and healthy controls.

People with multiple sclerosis (MS) have diminished postural control, and center of pressure (COP) displacement varies more in this population than in healthy controls. Balance-based torso-weighting (BBTW) can improve clinical balance and mobility in people with MS, and exploration using both linear and nonlinear measures of COP may help determine whether BBTW optimizes movement variability. The aim of this study was to investigate the effects of BBTW on people with MS and healthy controls during quiet standing. This was a quasi-experimental study comparing COP variability between groups, between eye closure conditions, and between weighting conditions in the anterior-posterior and medial-lateral directions. Twenty participants with MS and 18 healthy controls stood on a forceplate in 4 conditions: eyes open and closed and with and without BBTW. Linear measures of COP displacement included range and root mean square (RMS). Nonlinear measures included approximate entropy (ApEn) and Lyapunov exponent (LyE). Three-way repeated-measures analyses of variance compared measures across groups and conditions. The association between weighting response and baseline nonlinear variables was examined. When significant associations were found, MS subgroups were created and compared. The MS and control groups had significantly different range, RMS, and ApEn values. The eyes-open and eyes-closed conditions had significantly different range and RMS values. Change with weighting correlated with LyE (r=-.70) and ApEn (r=-.59). Two MS subgroups, with low and high baseline LyE values, responded to BBTW in opposite directions, with a significant main effect for weighting condition for the LyE variable in the medial-lateral direction. The small samples and no identification of impairments related to LyE at baseline were limitations of the study. The LyE may help differentiate subgroups who respond differently to BBTW. In both subgroups, LyE values moved toward the average of healthy controls, suggesting that BBTW may help optimize movement variability in people with MS. © 2014 American Physical Therapy Association.

Exposure to asbestos results in serious risk of developing lung and mesothelial diseases. Currently, there are no biomarkers that can be used to diagnose asbestos exposure. The purpose of the present study was to determine whether the levels or detection rate of chemokine (C-C motif) ligand 3 (CCL3) in the serum are elevated in persons exposed to asbestos. The primary study group consisted of 76 healthy subjects not exposed to asbestos and 172 healthy subjects possibly exposed to asbestos. The secondary study group consisted of 535 subjects possibly exposed to asbestos and diagnosed with pleural plaque (412), benign hydrothorax (10), asbestosis (86), lung cancer (17), and malignant mesothelioma (10). All study subjects who were possibly exposed to asbestos had a certificate of asbestos exposure issued by the Japanese Ministry of Health, Labour and Welfare. For the primary study group, levels of serum CCL3 did not differ between the two groups. However, the detection rate of CCL3 in the serum of healthy subjects possibly exposed to asbestos (30.2%) was significantly higher (P < 0.001) than for the control group (6.6%). The pleural plaque, benign hydrothorax, asbestosis, and lung cancer groups had serum CCL3 levels and detection rates similar to that of healthy subjects possibly exposed to asbestos. The CCL3 chemokine was detected in the serum of 9 of the 10 patients diagnosed with malignant mesothelioma. Three of the patients with malignant mesothelioma had exceptionally high CCL3 levels. Malignant mesothelioma cells from four biopsy cases and an autopsy case were positive for CCL3, possibly identifying the source of the CCL3 in the three malignant mesothelioma patients with exceptionally high serum CCL3 levels. In conclusion, a significantly higher percentage of healthy persons possibly exposed to asbestos had detectable levels of serum CCL3 compared to healthy unexposed control subjects. PMID:25940505

Cardiovascular Disease is the leading cause of death worldwide. Non-adherence to a recommended regimen among patients with Cardiovascular Diseases represents a significant problem which could lead to an increase in Cardiovascular Diseases. This study aimed to assess the effects of Short Message System (SMS) reminders on adherence to a healthy diet, medication, and cessation of smoking among adult patients with Cardiovascular Diseases. Randomized controlled trial design with three groups was used for this study. A non-probability convenient sample of 160 patients was recruited in this study. The participants were assigned randomly to an experimental group (received SMS regarding adherence to a healthy diet, medication, and smoking cessation), placebo group (received general messages) and control group (routine care). Morisky 8-Item Medication Adherence Scale (MMAS), Mediterranean Diet Adherence Screener (MEDAS), and Readiness to Quit Ladder, were used to assess patients' adherence to medication, adherence to Mediterranean diet, and smoking cessation, respectively. The outcomes were assessed at the beginning of the study and three months later, following completion of the intervention. One way ANONVA was used to assess the study hypothesis. Significant differences between study groups found in terms of adherence to medication (p=.001) and adherence to a healthy diet (p=.000); however, no significant difference was found between groups, in terms of intention to quit smoking, and/or the number of cigarettes smoked (p= .327), (p=.34), respectively. It is documented that SMS is effective in improving adherence to a healthy diet and medication. SMS could be a promising solution for management of different chronic diseases. It is recommended to apply Short Message System (SMS) via cellphone services to improve patient's adherence to a healthy diet and medication. However, further research is needed to support the effectiveness of SMS. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The present study aimed to investigate the association of cholinesterase activity with trypanosomosis in buffaloes. Thirty-three clinical cases of trypanosomosis in water buffaloes, found positive for trypomastigotes of T. evansi on blood smear examination, were divided into two groups based on clinical manifestations. Twenty diseased buffaloes revealing only common clinical signs were allocated to Group I, while the remaining 13 buffaloes showing common clinical manifestations along with neurological disturbances were allocated to Group II. Twelve clinically healthy buffaloes, free from any haemoprotozoa infection, were kept as healthy control (Group III). Blood samples were collected from buffaloes of all three groups to determine serum cholinesterase activity. Compared to buffaloes of healthy control group, cholinesterase activity in T. evansi-infected buffaloes of Group I and II was significantly (P<0.001) lower. However, no significant difference was observed in cholinesterase activity between the T. evansi-infected buffaloes exhibiting neurological disorders and no neurological disorders. Summing up, reduced cholinesterase activity seems to be associated with the pathogenesis of natural T. evansi infection and its clinical manifestations in buffaloes possibly by evading immune response. Further studies are warranted on association of cholinesterase activity in T. evansi-infected buffaloes with neurological disorders. Copyright © 2016 Elsevier B.V. All rights reserved.

Marble workers are occupationally exposed to intense environmental marble dust in their workplace. We aimed to investigate the effect of occupational marble dust exposure on nasal mucociliary transport rate (NMTR). Seventeen marble workers and 18 healthy controls were studied. In all subjects, NMTRs were measured by (99m)Tc-MAA rhinoscintigraphy. NMTRs of workers and control groups were compared by statistically. Mean NMTR was found as 9 ± 1.8 mm/min in marble workers whereas mean NMTR of healthy controls was 9.6 ± 2.2 mm/min. There was no statistically significant difference between NMTRs of workers and control groups (p > 0.05). This study has shown that occupationally exposured marble dusts may not cause functional impairment on NMTR in marble workshop workers.

Silicosis is considered an oxidative stress related disease that can lead to the development of lung cancer. In this study, our purpose was to analysis of volatile organic compounds (VOCs) in the exhaled breath of workers exposed to silica containing dust and compare peak area of these compounds with silicosis patients and healthy volunteers (smokers and nonsmokers) groups. In this cross sectional case-control study, the exhaled breath of 69 subjects including workers exposed to silica (n=20), silicosis patient (n=4), healthy non-smoker (n=20) and healthy smoker (n=25) were analyzed. We collected breath samples using 3-liter Tedlar bags. The VOCs were extracted with solid phase micro-extraction (SPME) and analyzed by gas chromatography-mass spectrometry (GC-MS). Personal exposure intensity was measured according to NIOSH 7601 method. Respiratory parameters were measured using spirometry. Seventy percent and 100% of the exposures to crystalline silica dust exceeded from 8 h TWA ACGIH TLVs in case and positive control groups, respectively. A significant negative correlation was found between dust exposure intensity and FEV1/FVC when exposure and positive control groups were studied in a group (r2=-0.601, P<0.001). Totally, forty VOCs were found in all exhaled breath samples. Among the VOCs, the mean of peak area acetaldehyde, hexanal, nonanal, decane, pentad cane, 2-propanol and 3-hydroxy-2-butanone were higher in exhaled breath of the workers exposed to silica and silicosis patient compared to the healthy smoker and nonsmoker controls. In some cases the difference was significant (P<0.05). The analysis of some VOCs in exhaled breath of subjects is appropriate biomarker to determine of exposure to silica.

Sickle cell disease (SCD) is an inherited blood disorder associated with significant morbidity, which includes severe episodic pain, and, often, chronic pain. Compared to healthy individuals, patients with SCD report enhanced sensitivity to thermal detection and pain thresholds and have altered inflammatory profiles, yet no studies to date have examined biomarker reactivity after laboratory-induced pain. We sought to examine this relationship in patients with SCD compared to healthy control participants. We completed quantitative sensory testing in 83 patients with SCD and sequential blood sampling in 27 of them, whom we matched (sex, age, race, body mass index, and education) to 27 healthy controls. Surprisingly, few quantitative sensory testing differences emerged between groups. Heat pain tolerance, pressure pain threshold at the trapezius, thumb, and quadriceps, and thermal temporal summation at 45°C differed between groups in the expected direction, whereas conditioned pain modulation and pain ratings to hot water hand immersion were counterintuitive, possibly because of tailoring the water temperature to a perceptual level; patients with SCD received milder temperatures. In the matched subsample, group differences and group-by-time interactions were observed in biomarkers including tumor necrosis factor alpha, interleukin-1ß, interleukin-4, and neuropeptide Y. These findings highlight the utility of laboratory pain testing methods for understanding individual differences in inflammatory cytokines. Our findings suggest amplified pain-evoked proinflammatory cytokine reactivity among patients with SCD relative to carefully matched controls. Future research is warranted to evaluate the impact of enhanced pain-related cytokine response and whether it is predictive of clinical characteristics and the frequency/severity of pain crises in patients with SCD.

Subclinical hypothyroidism is the precursor to hypothyroidism because it has a tendency to transform into hypothyroidism. Subclinical hypothyroidism is considered one of the risk factors causing metabolic syndrome. Metabolic syndrome can be characterized by plasma levels of apelin and lipocalin-2, both released from adipocytes. In the present study, we aimed to measure serum apelin and lipocalin-2 levels of patients with subclinical hypothyroidism and compare them with serum apelin and lipocalin-2 levels from healthy individuals. This was a cross-sectional study. A total of 80 subjects were enrolled in the study and divided into two groups: Group A included 39 patients (females, n=34) diagnosed with subclinical hypothyroidism, and Group B (the control group) comprised 41 healthy volunteers (females, n=38). Serum samples were obtained from each participant for the measurement of apelin and lipocalin-2. These were then stored at minus 80°C until the time of analysis, when serum apelin and lipocalin-2 levels of the two groups were compared. Patients with subclinical hypothyroidism (Group A and Group B subjects [healthy controls]) were comparable with respect to gender, age, and body mass index (BMI) (P=0.412, P=0.863, and P=0.269, respectively), nor was there a statistically significant difference between groups in terms of apelin and lipocalin-2 levels (P=0.87, and P=0.67, respectively). Apelin levels showed a positive and significant correlation with BMI (P=0.034). Serum lipocalin-2 levels showed significant positive correlations with BMI and creatinine levels (P=0.002, and P=0.025, respectively). In the present study, no significant difference of serum apelin and lipocalin-2 levels was observed between patients with subclinical hypothyroidism and healthy control subjects. Positive correlations were found, however, between serum apelin level and BMI as well as between serum lipocalin-2 and BMI and creatinine levels. Copyright © 2014. Published by Elsevier Masson SAS.

Transforming growth factor beta (TGFβ) is a family of genes that play a key role in mediating tissue remodeling in various forms of acute and chronic lung disease. In order to assess their role on pulmonary hypertension in broilers, we determined mRNA expression of genes of the TGFβ family and endothelin 1 in lung samples from 4-week-old chickens raised either under normal or cold temperature conditions. Both in control and cold-treated groups of broilers, endothelin 1 mRNA expression levels in lungs from ascitic chickens were higher than levels from healthy birds (P < 0.05), whereas levels in animals with cardiac failure were intermediate. Conversely, TGFβ2 and TGFβ3 gene expression in lungs were higher in healthy animals than in ascitic animals in both groups (P < 0.05). TGFβ1, TβRI, and TβRII mRNA gene expression among healthy, ascitic, and chickens with cardiac failure showed no differences (P > 0.05). BAMBI mRNA gene expression was lowest in birds with ascites only in the control group as compared with the values from healthy birds (P < 0.05). PMID:24286074

Treatment-resistant depression is comorbid with personality or anxiety disorder; how passive attention functions in these disorders remains unknown. A single tone-elicited event-related potential P3 component (passive P3) might help to characterize the passive attention in these disorders. The passive P3 test was applied to 32 patients with treatment-resistant depression, 35 with generalized anxiety disorder, and 21 with borderline personality disorder, as well as to 31 healthy volunteers. The Zung Self-rating Depression and Anxiety Scales were used to measure the respective depression and anxiety levels in these participants. All patients scored significantly higher on depression and anxiety than the healthy participants did. P3 amplitude was significantly reduced in groups with treatment-resistant depression and generalized anxiety disorder but not in the group with borderline personality disorder or healthy controls. Anxiety level was negatively correlated with P3 amplitude in healthy controls rather than in other groups. This study did not discriminate treatment-resistant depression and generalized anxiety disorder regarding the passive P3 but suggested that there was a generalized impairment of passive attention in these disorders.

Plasma norepinephrine and epinephrine in vibration syndrome subjects and age-matched healthy controls were measured for the purpose of estimating the responsibility of the sympathetic nervous system to cold exposure. In preliminary experiment, it was confirmed that cold air exposure of the whole body was more suitable than one-hand immersion in cold water. In the main experiment, 195 subjects were examined. Sixty-five subjects had vibration syndrome with vibration-induced white finger (VWF + group) and 65 subjects had vibration syndrome without VWF (VWF- group) and 65 controls had no symptoms (control group). In the three groups, plasma norepinephrine levels increased during cold air exposure of whole body at 7 degrees +/- 1.5 degrees C. Blood pressure increased and skin temperature decreased during cold exposure. Percent increase of norepinephrine in the VWF+ group was the highest while that in VWF- group followed and that in the control group was the lowest. This whole-body response of the sympathetic nervous system to cold conditions reflected the VWF which are characteristic symptoms of vibration syndrome. Excluding the effects of shivering and a cold feeling under cold conditions, it was confirmed that the sympathetic nervous system in vibration syndrome is activated more than in the controls. These results suggest that vibration exposure to hand and arm affects the sympathetic nervous system.

Microparticles are membrane bound vesicles, measuring less than 1.0 um, which are released during cellular activation or during apoptosis. Studies have shown that these circulating microparticles play a role in coagulation, cell signaling and cellular interactions. Increased levels of circulating microparticles have been observed in a number of conditions where there is vascular dysfunction, thrombosis and inflammation. The objective of this study was to determine the various plasma-derived microparticles in patients with polycythaemia vera (PV) in Universiti Kebangsaan Malaysia Medical Centre and to compare them with normal control. A total of 15 patients with PV and 15 healthy volunteers were included in this cross-sectional descriptive study. Plasma samples from both patients and healthy volunteers were prepared and further processed for isolation of microparticles. Flow cytometry analyses were then carried out in all samples to determine the cellular origin of the microparticles. Full blood count parameters for both groups were also collected. Data collected were analyzed using SPSS version 12.0. Patients with PV had a significantly higher percentage of platelet derived microparticles compared to healthy controls (P <0.05). The control group had a higher level of endothelial derived microparticles but the differences were not statistically significant (P > 0.05). The median percentage of positive events for platelet derived microparticles was higher in patients with PV compared to normal healthy controls.

Many older adults are concerned about memory changes with age and consequently seek ways to optimize their memory function. Memory programs are known to be variably effective in improving memory knowledge, other aspects of metamemory, and/or objective memory, but little is known about their impact on implementing and sustaining lifestyle and healthcare-seeking intentions and behaviors. We evaluated a multidimensional, evidence-based intervention, the Memory and Aging Program, that provides education about memory and memory change, training in the use of practical memory strategies, and support for implementation of healthy lifestyle behavior changes. In a randomized controlled trial, 42 healthy older adults participated in a program (n = 21) or a waitlist control (n = 21) group. Relative to the control group, participants in the program implemented more healthy lifestyle behaviors by the end of the program and maintained these changes 1 month later. Similarly, program participants reported a decreased intention to seek unnecessary medical attention for their memory immediately after the program and 1 month later. Findings support the use of multidimensional memory programs to promote healthy lifestyles and influence healthcare-seeking behaviors. Discussion focuses on implications of these changes for maximizing cognitive health and minimizing impact on healthcare resources.

ABSTRACT Introduction: Young Liberians, particularly undereducated young adults, face substantial sexual and reproductive health (SRH) challenges, with low uptake of contraceptive methods, high rates of unintended pregnancy, and low levels of knowledge about HIV status. The purpose of this study was to assess the impact of a 6-day intensive group learning intervention combined with on-site SRH services (called HealthyActions) among out-of-school young adults, implemented through an existing alternative education program, on uptake of contraception and HIV testing and counseling (HTC). Methods: The intervention was implemented among young women and men ages 15–35 who were enrolled in alternative basic education learning sites in 5 counties of Liberia. We conducted a randomized evaluation to assess program impact. Baseline data were collected in January–March 2014, and endline data in June–July 2014. Key outcomes of condom use, contraceptive use, and HTC were estimated with difference-in-difference models using fixed effects. All analyses were conducted in Stata 13. Results: We assessed outcomes for 1,157 learners at baseline and 1,052 learners at endline, across 29 treatment and 26 control sites. After adjusting for potential confounders, learners in the HealthyActions intervention group were 12% less likely to report never using a condom with a regular partner over the last month compared with the control group (P = .02). Female learners who received HealthyActions were 13% more likely to use any form of modern contraception compared with learners in control sites (P<.001), with the greatest increase in the use of contraceptive implants. Learners in HealthyActions sites were 45% more likely to have received HTC (P<.001). Conclusion: Providing intensive group learning in a supportive environment coupled with on-site health services improved SRH outcomes among participating learners. The focus of HealthyActions on participatory learning for low-literacy populations presents an adaptable solution for health programming across Liberia and the region. PMID:27688717

Attention difficulties are a common clinical complaint among children with epilepsy. We aimed to compare a range of attentional abilities between groups of children with two common epilepsy syndromes, Temporal Lobe Epilepsy (TLE) and Idiopathic Generalized Epilepsy (IGE), and to healthy controls. We also investigated whether epilepsy factors (laterality of seizure focus, epilepsy onset, duration, and severity) were related to attentional abilities. Multiple dimensions of attention (selective, sustained, and divided attention and attentional control) were assessed directly with standardized neuropsychological measures in 101 children aged 6-16years (23 children with TLE, 20 with IGE and 58 healthy controls). Attention was also assessed indirectly, via a parent-report measure. Children with TLE performed worse than children with IGE (p=0.013) and healthy controls (p<0.001) on a test of attentional control, but no between-group differences were apparent on tests of other attentional abilities. Compared to healthy controls, greater attention problems were reported by parents of children with TLE (p=0.006) and IGE (p=0.012). Left-hemisphere seizure focus and greater epilepsy severity were associated with poorer attentional control and sustained-divided attention, respectively, but no other epilepsy factors were associated with attentional abilities. These findings suggest that children with localization-related epilepsy, but not generalized epilepsy, may be at risk of deficits in attentional control. Interventions aimed at improving attentional control may be targeted at children with localization-related epilepsy, particularly those with a left-hemisphere seizure focus, who appear to be particularly susceptible to this type of attentional deficit.

The aim of the study was to measure the concentrations of vitamin D in serum of COPD patients with chronic respiratory failure in comparison to healthy control group. The correlation between the levels of vitamin D in serum and the selected clinical, spirometric and blood gas parameters was the additional aim of the study. The study included 61 patients with diagnosed COPD in stadium of chronic respiratory failure (45 men and 16 women) and 37 healthy controls (19 men and 18 women). The following procedure were performed in all studied subjects: detailed history (especially: daily activity, diet, tobacco and alcohol use), post-bronchodilator spirometry, assessment of 25(OH)D in serum and for COPD group only blood gas analysis. Recruitment for the study was conducted from November to April. Statistical analysis was performed using the following statistical methods: t-Student test, Mann-Whitney U test, Spearman correlation test and Chi-kwadrat test. There was no significant differences between COPD and control group for the levels of 25(OH)D in serum. Median and lower; upper quartile were respectively following: 24,75 nmol/l (16,9; 36,4) vs. 24,06 nmol/l (16,3; 37,2), p=0,69. Vitamin D deficiency was present in 60 COPD patients (98,3% of all patients) and in 36 control group subject (97,3% of all healthy volunteers). The difference was not statistically significant. The levels of vitamin D in serum did not significantly correlated with any of studied parameters (spirometry, blood gas, age, the level of activity, BMI, tobacco smoke exposure and others). However, the level of activity in COPD group correlated positively with spirometry values and negatively with age and number of exacerbations. The results of the study showed that in autumn-winter time in Poland there are very frequent deficiency of vitamin D in serum not only in COPD patients in respiratory failure stage but also in elderly healthy persons. However, in contrary to expectations the deficiency of vitamin D in COPD patients with respiratory failure were similar to that seen in healthy persons.

In healthy participants, cortisol administration has been found to impair autobiographic memory retrieval. We recently reported that administration of 10 mg of hydrocortisone had enhancing effects on autobiographical memory retrieval, i.e. more specific memory retrieval, in patients with posttraumatic stress disorder (PTSD), while in healthy controls the impairing effects were replicated. We here report a re-analysis of these data with respect to cue-word valence and retrieval time. In a placebo-controlled cross-over study, 43 patients with PTSD and 43 age- and sex-matched healthy controls received either placebo or hydrocortisone orally before the autobiographical memory test was performed. We found that the effects of cortisol on memory retrieval depended on cue-word valence and group (significant interaction effects of drug by group and drug by valence by group). The enhancing effect of cortisol on memory retrieval in PTSD seemed to be relatively independent of cue-word valence, while in the control group the impairing effects of cortisol were only seen in response to neutral cue-words. The second result of the study was that in patients as well as in controls, cortisol administration led to faster memory retrieval compared to placebo. This was seen in response to positive and (to lesser extend) to neutral cue-words, but not in response to negative cue-words. Our findings illustrate that the opposing effects of cortisol on autobiographical memory retrieval in PTSD patients and controls are further modulated by the emotionality of the cue-words.

Many researchers have reported a relationship between Internet addiction and depression. In the present study, we compared the resting-state quantitative electroencephalography (QEEG) activity of treatment-seeking patients with comorbid Internet addiction and depression with those of treatment-seeking patients with Internet addiction without depression, and healthy controls to investigate the neurobiological markers that differentiate pure Internet addiction from Internet addiction with comorbid depression. Thirty-five patients diagnosed with Internet addiction and 34 age-, sex-, and IQ-matched healthy controls were enrolled in this study. Patients with Internet addiction were divided into two groups according to the presence (N=18) or absence (N=17) of depression. Resting-state, eye-closed QEEG was recorded, and the absolute and relative power of the brain were analyzed. The Internet addiction group without depression had decreased absolute delta and beta powers in all brain regions, whereas the Internet addiction group with depression had increased relative theta and decreased relative alpha power in all regions. These neurophysiological changes were not related to clinical variables. The current findings reflect differential resting-state QEEG patterns between both groups of participants with Internet addiction and healthy controls and also suggest that decreased absolute delta and beta powers are neurobiological markers of Internet addiction.

Proprioception is essential for shoulder neuromuscular control and shoulder stability. Exercise of the rotator cuff and scapulothoracic muscles is an important part of shoulder rehabilitation. The purpose of this study was to investigate the effect of rotator cuff and scapulothoracic muscle exercises on shoulder joint position sense. Thirty-six healthy subjects were recruited and randomly assigned into either a control or training group. The subjects in the training group received closed-chain and open-chain exercises focusing on rotator cuff and scapulothoracic muscles for four weeks. Shoulder joint position sense errors in elevation, including the humerothoracic, glenohumeral and scapulothoracic joints, was measured. After four weeks of exercise training, strength increased overall in the training group, which demonstrated the effect of exercise on the muscular system. However, the changes in shoulder joint position sense errors in any individual joint of the subjects in the training group were not different from those of the control subjects. Therefore, exercises specifically targeting individual muscles with low intensity may not be sufficient to improve shoulder joint position sense in healthy subjects. Future work is needed to further investigate which types of exercise are more effective in improving joint position sense, and the mechanisms associated with those changes.

Sulcal depth-based cortical shape analysis in normal healthy control and schizophrenia groups

Sulcal depth is an important marker of brain anatomy in neuroscience/neurological function. Previously, sulcal depth has been explored at the region-of-interest (ROI) level to increase statistical sensitivity to group differences. In this paper, we present a fully automated method that enables inferences of ROI properties from a sulcal region- focused perspective consisting of two main components: 1) sulcal depth computation and 2) sulcal curve-based refined ROIs. In conventional statistical analysis, the average sulcal depth measurements are employed in several ROIs of the cortical surface. However, taking the average sulcal depth over the full ROI blurs overall sulcal depth measurements which may result in reduced sensitivity to detect sulcal depth changes in neurological and psychiatric disorders. To overcome such a blurring effect, we focus on sulcal fundic regions in each ROI by filtering out other gyral regions. Consequently, the proposed method results in more sensitive to group differences than a traditional ROI approach. In the experiment, we focused on a cortical morphological analysis to sulcal depth reduction in schizophrenia with a comparison to the normal healthy control group. We show that the proposed method is more sensitivity to abnormalities of sulcal depth in schizophrenia; sulcal depth is significantly smaller in most cortical lobes in schizophrenia compared to healthy controls (p < 0.05).

To compare the results of VEMP between unilateral definite Meniere's disease patients and normal healthy adults. Thirty-two patients with unilateral definite Meniere's disease patients and 32 age-matched normal healthy adults (control) underwent VEMP tests with short tone burst of 500 Hz at 90 dBnHL. Student-t test was used for comparison of means of all parameters between two groups. Absent VEMP response was found in 14 MD patients and abnormal asymmetry ratio (AR) was found in five MD patients. Normal responses were found in all subjects of the control group. The mean P1 and N1 latencies, VEMP amplitude between unilateral MD, and control were not significantly different between two groups. However the difference between the mean AR of both groups showed statistically significant (p-value < 0.05). The upper limit of normal AR was calculated to be of 35.15%. The absence of VEMP response and AR of VEMP were more dominant than other parameters such as P1 and N1 latencies or VEMP amplitude in the detection of saccular dysfunction in MD. The results suggested that AR should be used as a tool in interpretation of VEMP response for the diagnostic batteries in MD. The upper limit of normal AR of < or = 35% should be recommended.

The aim of this study was to compare attachment styles and psychopathology in adolescent children of parents with bipolar disorder (BD) with a healthy control group. We studied 25 adolescents who had at least 1 parent with BD (BD group) and 28 adolescents who had no parents with BD (control group). The adolescent participants were between the ages of 12 and 17 years. We used the Adolescent Relationship Scales Questionnaire (A-RSQ) for the adolescents in the BD vs. control groups, and we used the Schedule for Affective Disorders and Schizophrenia for School-age Children - present and lifetime version (K-SADS-PL). We used the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Clinician Version for each parent of adolescents in the BD and control groups to rule out psychopathologies. Attachment styles of participants were assessed according to A-RSQ, dismissing attachment style scores of adolescents in BD group were found significantly higher compared to the healthy control group (p<0.05). As a result of the assessments, 12 adolescents (48%) out of 25 in the BD group and 5 adolescents (18%) out of 28 in the control group were given DSM-IV Axis I diagnosis, which is a statistically significant result (p<0.05). However, when psychiatric diagnoses were assessed separately, the difference was not statistically significant. We found that the adolescent children of parents with BD have increased risk of developing mental illnesses, and that these adolescents adopt dismissing attachment styles.

To compare the effects of unilateral strength training by stimulated and voluntary contractions on muscle strength and monopedal postural control of the contralateral limb. 36 non-active healthy male subjects were recruited and split randomly into three groups. Two groups of 12 subjects took part in a strength-training program (3 sessions a week over 8 weeks) comprising 43 contractions of the quadriceps femoris of the ipsilateral limb (at 20% of the MVC). One group carried out voluntary contractions exclusively (VOL group), while the other group benefited exclusively from electro-induced contractions (NMES group). The other 12 subjects formed the control (CON) group. Assessments of MVC and monopedal postural control in static and dynamic postural tasks were performed with the ipsilateral (ISPI) and contralateral (CONTRA) limbs before (PRE) and after (POST) completion of the training program. After the training program, the MVC of the IPSI and CONTRA limbs increased similarly for both experimental groups (VOL and NMES). There were no significant improvements of monopedal postural control for the IPSI or CONTRA limbs in either the VOL or NMES experimental group. No change was observed for the CON group over the protocol period. The purposed training program with NMES vs VOL contractions induced strength gains but did not permit any improvement of contralateral monopedal postural control in healthy young subjects. This has potential for therapeutic application and allows clinicians to focus their training programs on dynamic and poly-articular exercises to improve the postural control in young subjects.

Background and Aims Probiotics, prebiotics and synbiotics have been suggested as dietary strategies to improve intestinal barrier function. This study aimed to assess the effect of two weeks synbiotic supplementation on intestinal permeability under basal and stressed conditions. Secondary aims were the assessment of two weeks synbiotic supplementation on systemic immune function and gastrointestinal symptoms including defecation pattern. Design Twenty healthy adults completed a double-blind, controlled, randomized, parallel design study. Intervention Groups either received synbiotic (1.5 × 1010 CFU Ecologic® 825 + 10 g fructo-oligosaccharides (FOS P6) per day) or control supplements for two weeks. Outcomes Intestinal segment specific permeability was assessed non-invasively by oral administration of multiple sugar probes and, subsequently, assessing the excretion of these probes in urine. This test was conducted at baseline and at the end of intervention, in the absence and in the presence of an indomethacin challenge. Indomethacin was applied to induce a compromised gut state. Plasma zonulin, cytokines and chemokines were measured at baseline and at the end of intervention. Gastrointestinal symptoms and stool frequency were recorded at baseline and daily during intervention. Results Significantly more male subjects were in the synbiotic group compared to the control group (P = 0.025). Indomethacin significantly increased urinary lactulose/rhamnose ratio versus without indomethacin, both in the control group (P = 0.005) and in the synbiotic group (P = 0.017). Urinary sugar recoveries and ratios, plasma levels of zonulin, cytokines and chemokines, and gastrointestinal symptom scores were not significantly different after control or synbiotic intervention. Stool frequency within the synbiotic group was significantly increased during synbiotic intervention compared to baseline (P = 0.039) and higher compared to control intervention (P = 0.045). Conclusion Two weeks Ecologic® 825/FOS P6 supplementation increased stool frequency, but did not affect intestinal permeability neither under basal nor under indomethacin-induced stressed conditions, immune function or gastrointestinal symptoms in healthy adults.

To compare the immediate implant success rates between sites with chronic apical lesions and healthy sites in the same patients 1 year postdelayed loading. One hundred sixty-eight immediate implants were placed in sixty patients at upper incisor, canine, and premolar sites. A split-mouth design was used, placing a minimum of two implants, one in a fresh socket associated with chronic periapical disease, the average lesion size was larger than 4 mm and less than 8 mm (test group), and the other(s) in a healthy fresh socket (control group). Implant survival rate at 1 year postloading delayed was compared between the groups. The implant survival rate was 98.2% for the total sample (n = 168); out of the three implants lost, two were from the test group, and one was from the control group (in the same patient as one of the former). Among the surviving implants, five were also considered failures due to excessive bone loss (n = 3) and also because of the recurrence of the periapical lesions (n = 2). Survival rates were significantly lower in the test than control sites at 12 months postloading. Implant survival rates were significantly lower after the immediate implantation in postextraction sockets associated with chronic periapical disease (90.8%) than in healthy postextraction sockets (98.1%). © 2015 Wiley Periodicals, Inc.

As a therapy modality, acupuncture is becoming popular for treating diseases. Nevertheless, the acupuncture mechanism of action remains unclear until now. Some studies suggest that acupuncture works by stimulating the β-endorphin release, whereas other studies show the opposite. This study aims to determine whether electro acupuncture at the LI 4 Hegu point could increase the plasma β-endorphin level as a basic of acupuncture mechanism of action. Thirty-six healthy subjects were involved and divided randomly into two groups, namely, intervention (n=18) and control (n=18). In the intervention group, electroacupuncture was applied at the LI 4 Hegu point with a low frequency for 30 min. In the control group, sham electroacupuncture was applied at a non-acupoint for 30 min. The plasma β-endorphin was examined before and after intervention using the ELISA method. A significant difference was found between the intervention and control groups in increasing the plasma β-endorphin level (9(50%) vs. 1(5.6%); p = 0.009). A significant difference was also observed in the plasma β-endorphin level after intervention between the two groups (35.1±3.4 vs. 10.3±1.8 p=0.003). Electroacupuncture at the LI 4 Hegu point was found to increase the plasma β-endorphin level in healthy subjects.

The aim of this study is to assess the reach and effectiveness of an integrated community-based intervention designed to promote physical activity and healthy eating among older adults in a socioeconomically disadvantaged community in the Netherlands. The intervention was evaluated with a controlled pre–post quasi-experimental design, with 430 randomly selected older adults participating in the intervention group and 213 in a control group at baseline. The intervention included a local media campaign and environmental approaches (e.g. community involvement) and was implemented during a 3-month high-intensity period, followed by a 6-month low-intensity one. Levels of physical activity and fruit and vegetable consumption were assessed at baseline and at 3 and 9 months after baseline. At the follow-up measurements, the intervention had reached respectively 68 and 69% of the participants in the intervention group. No significant differences were found between the intervention group and the control group in changes to any outcome except for transport-related PA at 3 and 9 months follow-up. The systematically developed community-based intervention reached a relatively large proportion of the participants, but had only small effects on the levels of physical activity and healthy eating in older adults in the short and medium term.

We defined the children according to the diagnosis criterion through Paul-Bunnell test inspecting the children's periphery blood unusual lymphocyte and detecting their anti-EBV-CA-IgM, anti-EBV-CA-IgG and anti-EBV-NA-IgG by ELISA and counted the ratio of CCR3 + and CCR5 + cells in lymphocytes with flow cytometry. The ratio of unusual lymphocyte in IM was higher than that of the healthy control group (P < 0.05). The ratio of CCR3 + cells in IM group was higher than that of the healthy control group (P < 0.05). The ratio of CCR5 + cells in IM group was significantly lower than that of the healthy control group. CCR3 + had direct interrelation with fever continued time and the ratio of unusual lymphocyte. There was a negative interrelation between CCR5 and fever continued time (P < 0.05). Children infectious of IM expressed higher level of CCR3 + and lower level of CCR5 + and there was a tendency of Th2 polarization with over production of T helper cell divide imbalance. CCR3 + and CCR5 + may be important targets to judge the degree of seriousness of IM.

The delivery of efficient nonpharmacological treatment to prevent the loss of muscle mass in older adults is a major challenge, and information on the combined effects of training and diet is particularly important. Here we aimed to evaluate the effects of 24 wk of resistance training combined with a healthy dietary approach (n-6/n-3 ratio < 2) in a population of healthy and physically active older women (65-70 years). The three-armed randomized controlled trial included a resistance training + healthy diet group (RT-HD), a resistance training group (RT), and controls (CON). All subjects included in the study were physically active and had low levels of serum inflammatory markers. In accordance with the dietary goals, the n-6/n-3 ratio dietary intake significantly decreased only in RT-HD by 42%. An increase in 1 repetition maximum in leg extension occurred in RT (+20.4%) and RT-HD (+20.8%), but not in CON. Interestingly, leg lean mass significantly increased only in RT-HD (+1.8%). While there were no changes in serum C-reactive protein and IL-6 levels, a significant decrease in serum level of the pro-inflammatory precursor arachidonic acid (-5.3 ± 9.4%) together with an increase in serum n-3 docosahexaenoic acid (+8.3%) occurred only in RT-HD. Altogether, this study demonstrates that the effects of resistance training on muscle mass in healthy older adults can be optimized by the adoption of a healthy diet.

Sometimes the suspicion is put forward that nutrition students show more disordered eating patterns, which may be among the motivating factors to study nutrition. At the same time, it is not clear whether the students' increasing knowledge about diet and nutrition is associated with a more healthy eating behaviour or with an unhealthy obsession with food choices. Cross-sectional comparison of nutrition students from German universities during the first year of their studies (n 123) and during higher semesters (n 96), with a control group from other study programmes (n 68 and n 46, respectively). Dietary restraint, disinhibition, the tendency towards orthorexia nervosa and healthy food choices were assessed using a questionnaire. Nutrition students showed higher levels of dietary restraint than the control group. Disinhibition and orthorexia nervosa did not differ between nutrition students and controls. Orthorexic tendencies were lower in the more advanced nutrition students. Healthy food choices did not differ among students in the first year. More advanced nutrition students showed healthier food choices, whereas the corresponding controls showed slightly more unhealthy food choices. Nutrition students, more than other students, tend to restrict their food intake in order to control their weight, but they do not have more disturbed or disordered eating patterns than other students. Moreover, during the course of their studies, they adopt slightly more healthy food choices and decrease their tendency to be obsessive in their eating behaviour.

Purpose Detection of cortical abnormalities in relapsing-remitting multiple sclerosis (RRMS) remains elusive. Structural MRI measures of cortical integrity are limited, although functional techniques such as pseudocontinuous Arterial Spin Labeling (pCASL) show promise as a surrogate marker of disease severity. We sought to determine the utility of pCASL to assess cortical cerebral blood flow (CBF) in RRMS patients with (RRMS-I) and without (RRMS-NI) cognitive impairment. Methods 19 age-matched healthy controls and 39 RRMS patients were prospectively recruited. Cognition was assessed using the MACFIMS battery. Cortical CBF was compared between groups using a mass univariate voxel-based morphometric analysis accounting for demographic and structural variable covariates. Results Cognitive impairment was present in 51.3% of patients. Significant CBF reduction was present in the RRMS-I compared to other groups in left frontal and right superior frontal cortex. Compared to healthy controls, RRMS-I displayed reduced CBF in the frontal, limbic, parietal and temporal cortex and putamen/thalamus. RRMS-I demonstrated reduced left superior frontal lobe cortical CBF compared to RRMS-NI. No significant cortical CBF differences were present between healthy controls and RRMS-NI. Conclusion Significant cortical CBF reduction occurs in RRMS-I compared to healthy controls and RRMS-NI in anatomically significant regions after controlling for structural and demographic differences.

To investigate whether goal-directed fluid therapy (GDFT) with the LiDCOrapid system can reduce the incidence of maternal hypotension and improve neonatal outcome. One hundred healthy term parturient women scheduled for elective cesarean section were recruited. After loading with 10 mL/kg Lactated Ringer's solution, parturient women were randomized to the GDFT and control group. In the GDFT group, individualized fluid therapy was implemented to optimize stroke volume, guided by the LiDCOrapid system. The control group received routine fluid therapy. Primary endpoints included onset of maternal hypotension, and vasopressor doses prior to delivery. The secondary endpoints included umbilical blood gas abnormalities and neonatal adverse events. Incidence of hypotension and mean phenylephrine dose administered prior to delivery were significantly higher in the control group than in the GDFT group (P < 0.01). There was no difference in Apgar score between the two groups. In the control group, mean umbilical artery and vein blood pH were significantly lower, corresponding to significantly higher incidences of neonatal hypercapnia and hypoxemia, compared with the GDFT group (P < 0.05). LiDCOrapid -guided GDFT may provide benefit to healthy parturient women and their newborns. © 2015 Japan Society of Obstetrics and Gynecology.

Restless legs syndrome (RLS) is a disturbing sensorimotor disorder negatively influencing both sleep and psychological functioning. The aim of the present study was to assess RLS patients with respect to locus of control, sleep-related personality traits, quality of life, and sleep as compared to healthy controls. Thirty-eight patients (18 females and 20 males; mean age: 56.06 years) diagnosed with RLS and an age- and gender-matched control group (n = 42) were recruited. Participants completed a series of questionnaires related to locus of control, personality traits, quality of life, and sleep. Compared to healthy controls, RLS patients had a lower internal locus of control, unfavourable sleep-related personality traits such as low self-confidence and higher mental arousal, poorer quality of life, and more depressive symptoms. Sleep was also affected. Multiple regression analyses showed that a low internal and a high external locus of control were predicted by RLS. The pattern of results suggests that RLS is associated with a low locus of control, negative personality traits, and poor quality of life as compared to healthy controls. Copyright © 2013 S.

This study examined the effects of a multimodal intervention on spontaneous brain activity in healthy older adults. Seventeen older adults received a six-week intervention that consisted of cognitive training, Tai Chi exercise, and group counseling, while 17 older adults in a control group attended health knowledge lectures. The intervention group demonstrated enhanced memory and social support compared to the control group. The amplitude of low frequency fluctuations (ALFF) in the middle frontal gyrus, superior frontal gyrus, and anterior cerebellum lobe was enhanced for the intervention group, while the control group showed reduced ALFF in these three regions. Moreover, changes in trail-making performance and well-being could be predicted by the intervention-induced changes in ALFF. Additionally, individual differences in the baseline ALFF were correlated with intervention-related changes in behavioral performance. These findings suggest that a multimodal intervention is effective in improving cognitive functions and well-being and can induce functional changes in the aging brain. The study extended previous training studies by suggesting resting-state ALFF as a marker of intervention-induced plasticity in older adults. PMID:25472002

Few studies have investigated emotional functioning in obsessive-compulsive personality disorder (OCPD). To explore the nature and extent of emotion difficulties in OCPD, the authors examined four domains of self-reported emotional functioning--negative affectivity, anger, emotion regulation, and emotion expressivity--in women with OCPD and compared them to a borderline personality disorder (BPD) group and a healthy control group. Data were collected as part of a larger psychophysiological experimental study on emotion regulation and personality. Compared to healthy controls, participants with OCPD reported significantly higher levels of negative affectivity, trait anger, emotional intensity, and emotion regulation difficulties. Emotion regulation difficulties included lack of emotional clarity, nonacceptance of emotional responses, and limited access to effective emotion regulation strategies. Participants with OCPD scored similarly to participants with BPD on only one variable, namely, problems engaging in goal-directed behavior when upset. Results suggest that OCPD may be characterized by notable difficulties in several emotional domains.

To investigate thiol/disulfide status using a novel automated assay in patients with age-related macular degeneration (AMD) compared to age-matched healthy controls. A total of 64 AMD patients [51 (79%) non-exudative, 13 (21%) exudative AMD] and 21 age-matched healthy control subjects were enrolled in this study. Plasma total thiol, native thiol, disulfide levels were measured and native thiol/disulfide ratio (TDR) was calculated using a novel spectrophotometric assay. Patients with AMD had significantly lower levels of total thiol (434.8 ± 7.0 μmol/L vs. 472.2 ± 7.9 μmol/L, p < 0.001), native thiol (393.6 ± 6.5 μmol/L vs. 437.5 ± 7.1 μmol/L, p = 0.004) compared to healthy controls. However, plasma disulfide levels were higher in AMD patients (20.6 ± 0.9 μmol/L vs. 17.3 ± 1.3 μmol/L, p = 0.113) compared to healthy controls. The TDR was not statistically different between the early AMD group and healthy controls (24.2 ± 2.3 vs. 29.5 ± 3.1, p = 0.345). However, intermediate and advanced stage AMD groups had significantly lower levels of TDR compared to healthy controls (21.6 ± 2.6 vs. 29.5 ± 3.1, p = 0.023 and 20.3 ± 1.2 vs. 29.5 ± 3.1, p = 0.005, respectively). Native TDR was significantly lower in patients with exudative and non-exudative AMD (19.9 ± 2.3 vs. 29.5 ± 3.1, p = 0.024 and 21.8 ± 1.14 vs. 29.47 ± 3.1 respectively, p = 0.011). A greater extent of thiol consumption occurred in AMD patients compared to age-matched healthy controls. However, despite the similar levels of total thiol levels between several grades of AMD, the plasma native TDR value was decreased in accordance with the severity of the disease, which reflected the disease grade better.

Yılmaz Ö, Türkeli A, Karaca Ö, Yüksel H. Does having an asthmatic sibling affect the quality of life in children? Turk J Pediatr 2017; 59: 274-280. Chronic illness in a family member leads to deterioration of quality of life in other members of that family. We aimed to investigate the influence of having an asthmatic sibling on a child`s quality of life (QoL). We enrolled 2-12 year aged healthy children with an asthmatic sibling in the study group and healthy children with a healthy sibling in the control group of this cross-sectional study. Sociodemographic characteristics of children and disease severity characteristics of asthmatic siblings were recorded. All parents filled in Turkish generic PedsQLTM short form appropriate for the child`s age group. Study and control groups had 114 children each. Total PedsQLTM scores were not significantly different in any of the age groups (p=0.23, p=0.13, p= 0.11 respectively). Emotional PedsQLTM sub-scores in children with an asthmatic sibling were significantly worse (83.0±16.5 vs 91.6±10.9 in the 2-4 year age group, 72.0±17.8 vs 92.2±11.6 in the 5-7 year age group, 73.7±24.1 vs 88.7±14.8 in the 8-12 year age group respectively, p≤0.002 for all). Similarly, psychosocial sub-score was significantly lower in the 2-4 and 5-7-year-olds but not the 8-12 year old groups (p=0.01, p=0.01, p=0.08 respectively). In conclusion, healthy children with asthmatic siblings have significantly lower emotional QoL and this needs to investigated for other chronic diseases in further research.

Decompensated diabetes is a major risk factor in the development of periodontal diseases. This leads to disturbances of carbohydrates, protein, and fat and morphological changes in many organs. These changes also apply to the masticatory system, especially periodontal tissues. The aim of the study was to assess the periodontal status and periodontal treatment needs in patients with non-controlled diabetes type 1 and type 2 (HbA1c > 7%), and to compare the results with the data obtained in a group of generally healthy patients. The study included 275 patients, 155 of them were patients with non-controlled diabetes during hospitalisation (study group), while 120 subjects constituted the control group of healthy people. The study excluded edentulous people. CPITN index (according to Ainamo et al.) was used to assess the periodontal state and periodontal treatment needs. The average level of glycated haemoglobin HbA1C among patients in the study group was 9.43% in women and slightly more at 9.57% in men. The periodontal status in healthy people was satisfactory, dominated by the maximum values of CPITN = 0, CPITN = 1, and CPITN = 2. The study group more frequently revealed the maximum values of CPITN = 3 and CPITN = 4. This shows the more advanced periodontal changes in this group. Due to the bad condition of the periodontium, the periodontal treatment needs proved to be far greater in the study group and related primarily to comprehensive specialist treatment (TN3). Decompensated diabetes may be an important cause of changes in periodontal tissues and may cause a significant loss of masticatory function in patients.

To evaluate effects of a single dose of enrofloxacin (5 mg/kg, IV) on body temperature and tracheobronchial neutrophil count in healthy Thoroughbreds premedicated with interferon-α and undergoing long-distance transportation. 32 healthy Thoroughbreds. All horses received interferon-α (0.5 U/kg, sublingually, q 24 h) as an immunologic stimulant for 2 days before transportation and on the day of transportation. Horses were randomly assigned to receive enrofloxacin (5 mg/kg, IV, once; enrofloxacin group) or saline (0.9% NaCl) solution (50 mL, IV, once; control group) ≤ 1 hour before being transported 1,210 km via commercial vans (duration, approx 26 hours). Before and after transportation, clinical examination, measurement of temperature per rectum, and hematologic analysis were performed for all horses; a tracheobronchial aspirate was collected for neutrophil quantification in 12 horses (6/group). Horses received antimicrobial treatment after transportation if deemed necessary by the attending clinician. No adverse effects were associated with treatment. After transportation, WBC count and serum amyloid A concentration in peripheral blood samples and neutrophil counts in tracheobronchial aspirates were significantly lower in horses of the enrofloxacin group than in untreated control horses. Fever (rectal temperature, ≥ 38.5°C) after transportation was detected in 3 of 16 enrofloxacin group horses and 9 of 16 control horses; additional antimicrobial treatment was required in 2 horses in the enrofloxacin group and 7 horses in the control group. In horses premedicated with interferon-α, enrofloxacin appeared to provide better protection against fever and lower respiratory tract inflammation than did saline solution.

Finger-tapping has been widely studied using behavioral and neuroimaging paradigms. Evidence supports the use of finger-tapping as an endophenotype in schizophrenia, but its relationship with motor procedural learning remains unexplored. To our knowledge, this study presents the first use of index finger-tapping to study procedural learning in individuals with schizophrenia or schizoaffective disorder (SCZ/SZA) as compared to healthy controls. A computerized index finger-tapping test was administered to 1169 SCZ/SZA patients (62% male, 88% right-handed), and 689 healthy controls (40% male, 93% right-handed). Number of taps per trial and learning slopes across trials for the dominant and non-dominant hands were examined for motor speed and procedural learning, respectively. Both healthy controls and SCZ/SZA patients demonstrated procedural learning for their dominant hand but not for their non-dominant hand. In addition, patients showed a greater capacity for procedural learning even though they demonstrated more variability in procedural learning compared to healthy controls. Left-handers of both groups performed better than right-handers and had less variability in mean number of taps between non-dominant and dominant hands. Males also had less variability in mean tap count between dominant and non-dominant hands than females. As expected, patients had a lower mean number of taps than healthy controls, males outperformed females and dominant-hand trials had more mean taps than non-dominant hand trials in both groups. The index finger-tapping test can measure both motor speed and procedural learning, and motor procedural learning may be intact in SCZ/SZA patients. Copyright © 2012 Elsevier B.V.

A healthy Nordic diet is associated with improvements in cardiometabolic risk factors, but the effect on lipidomic profile is not known. The aim was to investigate how a healthy Nordic diet affects the fasting plasma lipidomic profile in subjects with metabolic syndrome. Men and women (n = 200) with features of metabolic syndrome [mean age: 55 y; body mass index (in kg/m 2 ): 31.6] were randomly assigned to either a healthy Nordic (n = 104) or a control (n = 96) diet for 18 or 24 wk at 6 centers. Of the participants, 156 completed the study with plasma lipidomic measurements. The healthy Nordic diet consisted of whole grains, fruits, vegetables, berries, vegetable oils and margarines, fish, low-fat milk products, and low-fat meat. An average Nordic diet served as the control diet and included low-fiber cereal products, dairy fat-based spreads, regular-fat milk products, and a limited amount of fruits, vegetables, and berries. Lipidomic profiles were measured at baseline, week 12, and the end of the intervention (18 or 24 wk) by using ultraperformance liquid chromatography mass spectrometry. The effects of the diets on the lipid variables were analyzed with linear mixed-effects models. Data from centers with 18- or 24-wk duration were also analyzed separately. Changes in 21 plasma lipids differed significantly between the groups at week 12 (false discovery rate P < 0.05), including increases in plasmalogens and decreases in ceramides in the healthy Nordic diet group compared with the control group. At the end of the study, changes in lipidomic profiles did not differ between the groups. However, when the intervention lasted 24 wk, changes in 8 plasma lipids that had been identified at 12 wk, including plasmalogens, were sustained. There were no differences in changes in plasma lipids between groups with an intervention of 18 wk. By the dietary biomarker score, adherence to diet did not explain the difference in the results related to the duration of the study. A healthy Nordic diet transiently modified the plasma lipidomic profile, specifically by increasing the concentrations of antioxidative plasmalogens and decreasing insulin resistance-inducing ceramides.

To evaluate whether deficits of elbow flexor and extensor muscle strength exist in lateral epicondylalgia (LE) in comparison with a healthy control population. Cross-sectional study. 150 participants with unilateral LE were compared with 54 healthy control participants. Maximal isometric elbow flexion and extension strength were measured bilaterally using a purpose-built standing frame such that gripping was avoided. The authors found significant side differences in elbow extensor (-6.54 N, 95% CI -11.43 to -1.65, p=0.008, standardised mean difference (SMD) -0.45) and flexor muscle strength (-11.26 N, 95% CI -19.59 to -2.94, p=0.009, SMD -0.46) between LE and control groups. Within the LE group, only elbow extensor muscle strength deficits between sides was significant (affected-unaffected: -2.94 N, 95% CI -5.44 to -0.44). Small significant deficits of elbow extensor and flexor muscle strength exist in the affected arm of unilateral LE in comparison with healthy controls. Notably, comparing elbow strength between the affected and unaffected sides in unilateral epicondylalgia is likely to underestimate these deficits.

Recent study from our laboratory showed that patients with diabetes are at a higher risk of developing kidney cancer. In the current study, we have screened whole human DNA genome from healthy control, patients with diabetes or renal cell carcinoma (RCC) or RCC+diabetes. We found that 883 genes gain/163 genes loss of copy number in RCC+diabetes group, 669 genes gain/307 genes loss in RCC group and 458 genes gain/38 genes loss of copy number in diabetes group, after removing gain/loss genes obtained from healthy control group. Data analyzed for functional annotation enrichment pathways showed that control group had the highest number (280) of enriched pathways, 191 in diabetes+RCC group, 148 in RCC group, and 81 in diabetes group. The overlap GO pathways between RCC+diabetes and RCC groups showed that nine were enriched, between RCC+diabetes and diabetes groups was four and between diabetes and RCC groups was eight GO pathways. Overall, we observed majority of DNA alterations in patients from RCC+diabetes group. Interestingly, insulin receptor (INSR) is highly expressed and had gains in copy number in RCC+diabetes and diabetes groups. The changes in INSR copy number may use as a biomarker for predicting RCC development in diabetic patients. PMID:25821562

The aim of this study is to measure GABA levels of perisylvian cortices in schizophrenia and bipolar disorder patients, using proton magnetic resonance spectroscopy ( 1 H-MRS). Patients with schizophrenia (n=25), bipolar I disorder (BD-I; n=28) and bipolar II disorder (BD-II; n=20) were compared with healthy controls (n=30). 1 H-MRS data was acquired using a Siemens 3T whole body scanner to quantify right and left perisylvian structures' (including superior temporal lobes) GABA levels. Right perisylvian GABA values differed significantly between groups [χ 2 =9.62, df: 3, p=0.022]. GABA levels were significantly higher in the schizophrenia group compared with the healthy control group (p=0.002). Furthermore, Chlorpromazine equivalent doses of antipsychotics correlated with right hemisphere GABA levels (r 2 =0.68, p=0.006, n=33). GABA levels are elevated in the right hemisphere in patients with schizophrenia in comparison to bipolar disorder and healthy controls. The balance between excitatory and inhibitory controls over the cortical circuits may have direct relationship with GABAergic functions in auditory cortices. In addition, GABA levels may be altered by brain regions of interest, psychotropic medications, and clinical stage in schizophrenia and bipolar disorder. Copyright © 2016 Elsevier Ireland Ltd.

A randomized controlled pilot study was carried out to determine the effect of a 15-minute practice of ANB exercise on experimentally induced anxiety using the simulated public speaking model in yoga-naïve healthy young adults. Thirty consenting medical students were equally divided into test and control groups. The test group performed alternate nostril breathing exercise for 15 minutes, while the control group sat in a quiet room before participating in the simulated public speaking test (SPST). Visual Analog Mood Scale and Self-Statements during Public Speaking scale were used to measure the mood state at different phases of the SPST. The psychometric scores of both groups were comparable at baseline. Repeated-measures ANOVA showed a significant effect of phase ( p < 0.05), but group and gender did not have statistically significant influence on the mean anxiety scores. However, the test group showed a trend towards lower mean scores for the anxiety factor when compared with the control group. Considering the limitations of this pilot study and the trend seen towards lower anxiety in the test group, alternate nostril breathing may have potential anxiolytic effect in acute stressful situations. A study with larger sample size is therefore warranted. This trial is registered with CTRI/2014/03/004460.

The superficial digital flexor tendon (SDFT) is a structure frequently affected by injuries in high-performance athletic horses, and there are limited therapeutic options. Regenerative medicine has evolved significantly in treating different illnesses. However, understanding the cellular behaviour during mesenchymal stem cell (MSC) transplantation in healthy tissues is not fully known yet. To address the inflammatory response induced by allogeneic MSC transplantation, this study evaluated the local inflammatory response after the application of allogeneic adipose tissue-derived mesenchymal stem cells (AT-MSCs) in the equine tendon compared to an autologous transplant and the control group. Eighteen thoracic limbs (TL) in nine animals were divided into three groups and subjected to the application of AT-MSCs in the healthy tendon. In the allogeneic group (Gallog), the animals received an allogeneic AT-MSC application in the TL. The autologous group (Gauto) received an application of autologous cells in the TL, and in the control group (Gcont), phosphate-buffered saline (PBS) was applied. There were no significant differences among the evaluated groups in the physical, morphological, thermography, and ultrasonography analyses. A higher number of CD3-positive lymphocytes was observed in the Gauto group compared to the control (P < 0.05). Additionally, we did not observe different expressions of CD172 and microvascular density among the groups. The allogeneic transplantation of AT-MSCs did not result in an adverse or inflammatory reaction that compromised the use of these cells in this experiment. Their behaviour was similar to that of autologous transplantation. Copyright © 2018. Published by Elsevier Ltd.

Purpose To compare both retinal nerve fiber layer thickness and orbital color Doppler ultrasonography parameters in patients with multiple sclerosis (MS) versus healthy controls. Methods This is an observational case–control study. Forty eyes from MS patients and twenty eyes from healthy volunteers were examined. Eyes were classified into three groups as group 1, eyes from MS patients with previous optic neuritis (n=20); group 2, eyes from MS patients without previous optic neuritis (n=20); and group 3, eyes from healthy controls (n=20). Following complete ophthalmologic examination and retinal nerve fiber layer thickness measurement for each group, blood flow velocities of posterior ciliary arteries, central retinal artery, ophthalmic artery, and superior ophthalmic vein were measured. Pourcelot index (resistive index), an indicator of peripheral vascular resistance, was also calculated. The statistical assessment was performed with the assistance of Pearson's Chi-square test, Mann–Whitney U-test, Kruskal–Wallis test, and Spearman's correlation test. Results The studied eyes exposed similar values in terms of intraocular pressure and central corneal thickness, implying no evidence in favor of glaucoma. All nerve fiber layer thickness values, except superior nasal quadrants, in group 1 were found to be significantly thinner than groups 2 and 3. Blood flow velocity and mean resistivity index parameters were similar in all the groups. Conclusions In MS patients, especially with previous optic neuritis, diminished retinal nerve fiber layer thickness was observed. Contrary to several studies in the current literature, no evidence supporting potential vascular origin of ocular involvement in MS was found. PMID:25081285

In order to evaluate the elemental concentration as a function of learning and memory deficiency, six different structures of the brain were analyzed by total reflection X-ray fluorescence spectrometry with synchrotron radiation (SR-TXRF). To evaluate the cognitive processes, the animals were tested in an adaptation of the Morris water maze. After the test, the animals were divided into two groups: cognitively healthy (control group) and cognitively impaired. The measurements were carried out at XRF beam line at Light Synchrotron Brazilian laboratory, Campinas, Brazil. The following elements were identified: Al, P, S, Cl, K, Ca, Ti, Cr, Fe, Cu, Zn, Br and Rb. K concentration was higher in all regions of the brain studied for control group than the cognitively impaired group. Moreover, the control group presented higher levels for P and Fe in the entorhinal cortex, in the temporal cortex (only P), in the hypothalamus and in the thalamus, than the cognitively impaired group. Br concentration in the animals which presented cognitive impairment was three times larger in the hypothalamus and thalamus, twice larger in temporal cortex and higher in visual cortex than the cognitively healthy group. Cu was more remarkable in the hippocampus and hypothalamus from the animals with cognitive impairment than the control group. We observed that the cognitively impaired group presented highest concentrations of Br and Cu in certain areas than the control group, on the other hand, this group presented highest levels of K for all brain areas studied.

IMPORTANCE A genetic polymorphism affecting FUT2 secretor status in approximately one-quarter of humans of European descent affects the expression of histo-blood group antigens on the mucosal epithelia of human respiratory, genitourinary, and digestive tracts. These histo-blood group antigens serve as host receptor sites necessary for attachment and infection of some pathogens, including norovirus. OBJECTIVE We investigated whether an association exists between FUT2 secretor status and laboratory-confirmed rotavirus infections in US children. DESIGN, SETTING, AND PARTICIPANTS Multicenter case-control observational study involving active surveillance at 6 US pediatric medical institutions in the inpatient and emergency department clinical settings. We enrolled 1564 children younger than 5 years with acute gastroenteritis (diarrhea and/or vomiting) and 818 healthy controls frequency matched by age and month, from December 1, 2011, through March 31, 2013. MAIN OUTCOMES AND MEASURES Paired fecal-saliva specimens were tested for rotavirus and for secretor status. Comparisons were made between rotavirus test–positive cases and healthy controls stratified by ethnicity and vaccination status. Adjusted multivariable analyses assessed the preventive association of secretor status against severe rotavirus gastroenteritis. RESULTS One (0.5%) of 189 rotavirus test–positive cases was a nonsecretor, compared with 188 (23%) of 818 healthy control participants (P < .001). Healthy control participants of Hispanic ethnicity were significantly less likely to be nonsecretors (13%) compared with healthy children who were not of Hispanic ethnicity (25%) (P < .001). After controlling for vaccination and other factors, children with the nonsecretor FUT2 polymorphism appeared statistically protected (98% [95% CI, 84%–100%]) against severe rotavirus gastroenteritis. CONCLUSIONS AND RELEVANCE Severe rotavirus gastroenteritis was virtually absent among US children who had a genetic polymorphism that inactivates FUT2 expression on the intestinal epithelium. We observed a strong epidemiologic association among children with rotavirus gastroenteritis compared with healthy control participants. The exact cellular mechanism behind this epidemiologic association remains unclear, but evidence suggests that it may be rotavirus genotype specific. The lower prevalence of nonsecretors among Hispanic children may translate to an enhanced burden of rotavirus gastroenteritis among this group. Our findings may have bearing on our full understanding of rotavirus infections and the effects of vaccination in diverse populations. PMID:26389824

Low levels of the vitamin D-regulated antimicrobial peptide cathelicidin (LL-37) may negatively impact the immune status of human immunodeficiency virus-1 (HIV-1) infected individuals (HIV+). We compared plasma LL-37 levels in healthy controls (HIV−) and HIV+ individuals on or off antiretroviral therapies (ARTs) (ART+ and ART−, respectively), and evaluated the relationship between vitamin D and LL-37 levels. In this cross-sectional study, levels of LL-37, 25-hydroxycholecalciferol [25(OH)D3] and 1,25-dihydroxycholecalciferol [1,25(OH)2D3] were measured from an initial cohort of 18 healthy controls and 10 HIV+/ART− individuals. Because this cohort lacked HIV+/ART+ subjects, LL-37 was also quantified from a second cohort of 10 HIV+/ART− and 13 HIV+/ART+ individuals. LL-37 levels were significantly lower in the HIV+/ART− group compared to the healthy controls (P = 0.01). A direct relationship was observed between LL-37 and both 25(OH)D3 and 1,25(OH)2D3. The level of 25(OH)D3 was predictive of higher LL-37 (P = 0.04) and for any given level of 25(OH)D3, HIV+/ART− subjects averaged 20 % lower LL-37 compared to the healthy controls (P = 0.045). For any given level of 1,25(OH)2D3, HIV+/ART− subjects averaged 25 % lower LL-37 compared to the healthy controls (P = 0.018), although 1,25(OH)2D3 was not predictive of higher LL-37 (P = 0.28). Finally, LL-37 levels were significantly lower in the HIV+/ART− group compared to the HIV+/ART+ group from the second cohort (P = 0.045). Untreated HIV infection may contribute to lower LL-37 levels, independent of vitamin D levels. ART treatment may potentially mitigate this decrease in LL-37 levels. PMID:24821067

A suitable culture system is important for follicle growth in adult bovine ovarian tissue. This study aimed to assess the avian chorioallantoic membrane (CAM) for short-term culture of adult bovine ovarian tissues compared with a traditional in vitro culture system. Ovarian cortical tissues (1-2 mm 3 ), collected from slaughtered adult cows, were randomly assigned to control, CAM or in vitro culture groups. In the control group, ovarian tissues were fixed with paraformaldehyde without culture. In CAM and in vitro culture groups, the ovarian tissues were cultured for up to 5 days and then fixed. Ovarian tissues were examined on culture days 0, 1, 3 and 5 for angiogenesis, follicle morphology and growth. In all groups, primordial and growing (healthy and atretic) follicle densities were determined. In the CAM culture, the avian blood vessel density increased (p < 0.01) over time with a decline (p < 0.001) in the bovine blood vessel density. Healthy primordial, atretic primordial and healthy growing follicle densities were higher (p < 0.05) in CAM-cultured ovarian tissues than in vitro-cultured tissues. Regardless of the culture system, the density of healthy primordial follicles decreased (p < 0.001) over time with an increase in healthy growing follicles on day 3 (p < 0.01) and an increase in atretic (primordial and growing) follicles during the 5-day culture period (p < 0.001). The proportions of healthy primordial and atretic growing follicles were also affected by culture day (p < 0.001). The CAM culture in chick embryos supported the bovine ovarian tissue grafts for 3 days demonstrating that CAM can be used as a satisfactory short-term culture system to assess ovarian tissue health, and to study follicle activation and development.

Increased Serum insulin-like growth factor-1 (S-IGF-1) has been noted after physical activity in healthy subjects, while the acute release of S-IGF-1 in relation to exercise has not previously been studied in women with fibromyalgia (FM). S-IGF-1 and its binding protein (S-IGFBP-3) are mediated by growth hormone and have anabolic effects on the skeletal muscle. Aim of the study was to investigate acute release of IGF-1 after aerobic exercise in women with FM. The acute effect of physical exercise on S-IGF-1 and S-IGFBP-3 were studied in 22 women with FM and in 27 healthy controls during moderate and high-intensity cycling (i.e. ratings 12-13 and 15-17, on Borg's perceived exertion scale (RPE), respectively). Self-reported pain and fatigue were recorded. Differences within and between the two groups were analyzed. After 15 min of bicycling, S-IGF-1 and S-IGFBP-3 increased both within the group with FM and in the healthy controls (p < 0.01). The increases in S-IGF-1 did not significantly differ between the women with FM and the healthy control group (mean increase 11 ± 10 vs. 11 ± 15 ng/ml and 13 ± 10 vs. 19 ± 22 ng/ml) when bicycling at moderate or high intensity, respectively. Self-reported pain and fatigue during exercise, irrespective of intensity, were higher in women with FM compared with healthy controls (p < 0.001). Fifteen minutes bicycling at moderate intensity was sufficient to acutely mobilise S-IGF-1 in women with FM similarly to healthy controls in spite of higher score of fatigue and pain in women with FM. Hence, patients with FM were able to activate their skeletal muscle metabolism during a short, moderate bout of exercise and were not resistant to training effects. The result is important for encouraging clinical rehabilitation of patients with FM who commonly exercise at a moderate, rather than at a high-intensity level.

To compare the effect of posterior corneal astigmatism on the estimation of total corneal astigmatism using anterior corneal measurements (simulated keratometry [K]) between eyes with keratoconus and healthy eyes. Thirty-three eyes of 33 patients with keratoconus of grade I or II and 33 eyes of 33 age- and sex-matched healthy control subjects were enrolled. Anterior, posterior, and total corneal cylinder powers and flat meridians measured by a single Scheimpflug camera were analyzed. The difference in corneal astigmatism between the simulated K and total cornea was evaluated. The mean anterior, posterior, and total corneal cylinder powers of the keratoconus group (4.37 ± 1.73, 0.95 ± 0.39, and 4.36 ± 1.74 CD, respectively) were significantly greater than those of the control group (1.10 ± 0.68, 0.39 ± 0.18, and 0.97 ± 0.63 CD, respectively). The cylinder power difference between the simulated K and total cornea was positively correlated with the posterior corneal cylinder power and negatively correlated with the absolute flat meridian difference between the simulated K and total cornea in both groups. The mean magnitude of the vector difference between the astigmatism of the simulated K and total cornea of the keratoconus group (0.67 ± 0.67 CD) was significantly larger than that of the control group (0.28 ± 0.12 CD). Eyes with keratoconus had greater estimation errors of total corneal astigmatism based on anterior corneal measurement than did healthy eyes. Posterior corneal surface measurement should be more emphasized to determine the total corneal astigmatism in eyes with keratoconus. © 2018 The Korean Ophthalmological Society.

Diabetes has various interactions with ischemic heart diseases. Troxerutin, a flavonoid, owns outstanding pharmacological potentials in cardiovascular medicine. The purpose of this study was to investigate the effects of troxerutin on phosphorylation of GSK-3β protein and apoptosis induced by myocardial ischemia-reperfusion injury in healthy and diabetic hearts. Male Wistar rats (n=36, 250-300 g) were randomly divided into four groups: healthy, diabetic, healthy-troxerutin and diabetic-troxerutin. Diabetes was induced by a single injection of streptozotocin (50 mg/kg; ip) and the diabetic period was lasted for ten weeks. Six weeks after induction of diabetes, troxerutin-treated groups received 150 mg/kg/day troxerutin by oral gavage for 4 weeks. The rats' hearts were transferred to the Langendorff apparatus and then subjected to 30 min regional ischemia followed by 45 min reperfusion. Supernatants of the left ventricle were used to measure the levels of cardiac troponin-I (cTnI) by ELISA, total and phosphorylated form of GSK-3β by western blotting and tissue apoptosis by TUNEL assay. Troxerutin administration significantly decreased the cTnI levels in healthy and diabetic groups, as compared to the corresponding controls (P<0.05). In addition, troxerutin significantly increased the level of phosphorylated form and the ratio of phosphorylated to total form of GSK-3β in diabetic and control groups (P<0.05). Tissue apoptosis level and apoptotic index also showed a significant decrease after administration of troxerutin in control and diabetic groups (P<0.05). The findings indicated that the attenuation of GSK-3β activity and subsequent reduction of apoptosis by troxerutin play significant roles in its cardioprotection on reperfusion injuries.

Food preferences are established in early childhood and track later in life. Therefore, it is important to promote healthy feeding practices as early as possible. A randomized field trial was conducted with 500 mother-child pairs from a low-income area of São Leopoldo, State of Rio Grande do Sul, Brazil, to evaluate the impact of a nutritional intervention in the first year of life on the dietary quality of 3- to 4-y-old children. Mother-child pairs were randomized either to intervention and control groups and dietary counseling was provided for mothers in the intervention group during 10 home visits in the course of the first year of life. These visits were carried out by fieldworkers who counseled the mothers about the Ten Steps for Healthy Feeding from Birth to Two Years of Age, based on the WHO guidelines. Dietary intake was assessed at 3-4 y of age for 345 children using two 24-h food recalls. Overall diet quality was determined by the Healthy Eating Index. The prevalence of poor diet in the intervention group was lower compared with the control group [relative risk (RR) = 0.30; 95% CI = 0.13-0.71). The number of children who achieved the 75th percentile for the vegetable and fruit component score was higher in the intervention than in control group (RR = 1.95; 95% CI = 1.31-2.89 and RR = 1.49; 95% CI = 1.07-2.07, respectively). Such data provide evidence that dietary counseling for mothers during the first year of life improves the overall dietary quality of children in a low-income population.

The aim of this study was to assess the kinematics disorder of gait in men with fibromyalgia. We studied 12 male with fibromyalgia and 14 healthy men. Each participant of the study walked five trials along a 18.6-m walkway. Fibromyalgia patients completed a Spanish version of Fibromyalgia Impact Questionnaire. Significant differences between fibromyalgia and control groups were found in velocity, stride length, and cadence. Gait parameters of men affected by fibromyalgia were impaired when compared to those of healthy group due to bradykinesia. According to previous studies to assess gait variables in female patients, the male with fibromyalgia also showed lower values of velocity, cadence, and stride length than healthy group but not reported significant differences in swing, stance, single, or double support phase.

Objective: To explore the whole brain activity features of childhood and adolescence-onset schizophrenia using resting state fMRI. Methods: A total of 63 childhood and adolescence-onset schizophrenia patients (patients group), admitted to the second affiliated hospital of Xinxiang Medical University from October 2013 to October 2015 and fulfilled our inclusion criteria, and 39 healthy controls with age, sex and education matched (control group) were enrolled, then a resting-state fMRI scan was conducted for each participant. Fractional amplitude of low-frequency fluctuations (fALFF) approach was used to explore the differences of resting-state brain function between patients and controls. Results: Compared with the healthy control group, patients group showed significantly decreased fALFF in left superior temporal gyrus and parietal lobe (MNI coordinate: x =-42, -57; y =-3, -21; z =-12, 9; voxels: 22, 32; t =-4.792 3, -5.269 7; Alphasim corrected, corrected P <0.05); patients group showed significantly increased fALFF in left frontal lobe and medial frontal gyrus, right superior frontal gyrus, Postcentral Gyrus, caudate, (MNI coordinate: x =-42, -21, 12, 27, 15; y=54, 39, 48, -18, 15; z =0, 21, 33, 30, 9; voxels: 12, 21, 17, 28, 18; t =4.784 8, 4.90 7, 4.861 5, 5.444 1, 4.270 4; Alphasim corrected, corrected P <0.05). When included age as a covariant, the analysis found that the brain region with significant fALFF change was the left thalamus with decreased fALFF (MNI coordinate: x =-6, y =-12, z=24; voxels: 9; t =-4.268 4; Alphasim corrected, corrected P <0.05) in patients group, while for other brain regions, there was no obvious change in the fALFF, compared with healthy group. Conclusion: Compared with control group, the results indicate that there are intrinsic brain activity abnormalities of some brain regions in childhood and adolescence-onset schizophrenia.

To evaluate the effects of hydrotalcite combined with esomeprazole on gastric ulcer healing quality. Forty-eight patients diagnosed with gastric ulcer between June 2014 and February 2016 were randomly allocated to the combination therapy group or monotherapy group. The former received hydrotalcite combined with esomeprazole, and the latter received esomeprazole alone, for 8 wk. Twenty-four healthy volunteers were recruited and acted as the healthy control group. Endoscopic ulcer healing was observed using white light endoscopy and narrow band imaging magnifying endoscopy. The composition of collagen fibers, amount of collagen deposition, expression of factor VIII and TGF-β1, and hydroxyproline content were analyzed by Masson staining, immunohistochemistry, immunofluorescent imaging and ELISA. Following treatment, changes in the gastric microvascular network were statistically different between the combination therapy group and the monotherapy group ( P < 0.05). There were significant differences ( P < 0.05) in collagen deposition, expression level of Factor VIII and TGF-β1, and hydroxyproline content in the two treatment groups compared with the healthy control group. These parameters in the combination therapy group were significantly higher than in the monotherapy group ( P < 0.05). The ratio of collagen I to collagen III was statistically different among the three groups, and was significantly higher in the combination therapy group than in the monotherapy group ( P < 0.05). Hydrotalcite combined with esomeprazole is superior to esomeprazole alone in improving gastric ulcer healing quality in terms of improving microvascular morphology, degree of structure maturity and function of regenerated mucosa.

Around 60% of persons with multiple sclerosis (MS) experience falls, however the dynamic balance differences between those who fall and those who don't are not well understood. The purpose of this study is to identify distinct biomechanical features of dynamic balance during gait that are different between fallers with MS, non-fallers with MS, and healthy controls. 27 recurrent fallers with MS, 28 persons with MS with no falls history, and 27 healthy controls walked on a treadmill at their preferred speed for 3min. The variability of trunk accelerations and the average and variability of minimum toe clearance, spatiotemporal parameters, and margin of stability were compared between groups. Fallers with MS exhibited a slower cautious gait compared to non-fallers and healthy controls, but had decreased anterior-posterior margin of stability and minimum toe clearance. Fallers walked with less locally stable and predictable trunk accelerations, and increased variability of step length, stride time, and both anterior-posterior and mediolateral margin of stability compared to non-fallers and healthy controls. The present work provides evidence that within a group of persons with MS, there are gait differences that are influenced by falls history. These differences indicate that in persons with MS who fall, the center of mass is poorly controlled through base of support placement and the foot is closer to the ground during swing phase relative to the non-fallers. These identified biomechanical differences could be used to evaluate dynamic balance in persons with MS and to help improve fall prevention strategies. Copyright © 2017. Published by Elsevier Ltd.

Emotional face processing and flat affect in schizophrenia: functional and structural neural correlates.

There is a general consensus in the literature that schizophrenia causes difficulties with facial emotion perception and discrimination. Functional brain imaging studies have observed reduced limbic activity during facial emotion perception but few studies have examined the relation to flat affect severity. A total of 26 people with schizophrenia and 26 healthy controls took part in this event-related functional magnetic resonance imaging study. Sad, happy and neutral faces were presented in a pseudo-random order and participants indicated the gender of the face presented. Manual segmentation of the amygdala was performed on a structural T1 image. Both the schizophrenia group and the healthy control group rated the emotional valence of facial expressions similarly. Both groups exhibited increased brain activity during the perception of emotional faces relative to neutral ones in multiple brain regions, including multiple prefrontal regions bilaterally, the right amygdala, right cingulate cortex and cuneus. Group comparisons, however, revealed increased activity in the healthy group in the anterior cingulate, right parahippocampal gyrus and multiple visual areas. In schizophrenia, the severity of flat affect correlated significantly with neural activity in several brain areas including the amygdala and parahippocampal region bilaterally. These results suggest that many of the brain regions involved in emotional face perception, including the amygdala, are equally recruited in both schizophrenia and controls, but flat affect can also moderate activity in some other brain regions, notably in the left amygdala and parahippocampal gyrus bilaterally. There were no significant group differences in the volume of the amygdala.

To determine the effect of the daily intake of calcium and vitamin D-enriched milk (with or without fructooligosaccharides [FOS]) on vitamin D, bone metabolism, and cardiovascular risk factors. Two-year randomized controlled study, including 500 healthy postmenopausal women, assigned to 500 mL/day of skimmed milk to one of three groups: Low-dose (L): (120 mg/100 mL calcium, vitamin D 3 30 UI/100 mL), group A: calcium and vitamin D (180 mg/100 mL and 120 UI/100 mL), and group B: calcium and vitamin D (180 mg/100 mL and 120 UI/100 mL) and FOS (5 g/L). We evaluated serum 25(OH)D, bone mineral density (BMD) by Dual Energy X-ray Absorptiometry, and biochemical data of glucose and lipid metabolism. After 24 months, vitamin D concentrations did not change in the control group, but increased in group A and group B, p < 0.001. We observed an increase in femoral neck BMD and an improvement in fasting plasma glucose, HbA 1c , total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B 100. Daily intake of milk enriched with calcium and vitamin D in postmenopausal healthy women induces a significant improvement in vitamin D status, a significant increase in BMD at femoral neck, and also favorable effects on glucose and lipid profile.

Disruptive behavior disorder (DBD) is a well-known risk factor for substance abuse and delinquent behavior in adolescence. Therefore, the long-term preventive effects of treatment of DBD in middle childhood on beginning substance use and delinquency in early adolescence were investigated. Children with DBD (8-13 years old) had been randomly assigned to manualized behavior therapy (Utrecht Coping Power Program; UCPP) or to care as usual (CU) in the Netherlands. Five years (2003-2005) after the start of treatment (1996-1999), substance use and delinquency were monitored in 61 of the initial 77 adolescents and compared with a matched healthy control group by means of self-report questionnaires. One-factor analyses of variance and Pearson's chi2 analyses were performed. Differences in substance use were revealed in favor of the UCPP, with more adolescents in the CU group smoking cigarettes in the last month (UCPP 17%, CU 42%; chi2 = 4.7; p < .03) and more adolescents in the CU group having ever used marijuana (UCPP 13%, CU 35%; chi2 = 4.0; p < .045). Moreover, in this respect, the UCPP fit in the range of the matched healthy control group. Both treatment groups were comparable to the matched healthy control group in delinquent behavior. Manualized behavior therapy for DBD in middle childhood seems to be more powerful than CU in reducing substance use in early adolescence. Both treatment conditions show a beneficial long-term preventive effect on delinquency.

The primary aim of this study was to evaluate the effectiveness of an intervention to increase the implementation of healthy eating and physical activity policies and practices by centre-based childcare services. The study also sought to determine if the intervention was effective in improving child dietary intake and increasing child physical activity levels while attending childcare. A parallel group, randomised controlled trial was conducted in a sample of 128 childcare services. Intervention strategies included provision of implementation support staff, securing executive support, staff training, consensus processes, academic detailing visits, tools and resources, performance monitoring and feedback and a communications strategy. The primary outcome of the trial was the proportion of services implementing all seven healthy eating and physical activity policies and practices targeted by the intervention. Outcome data were collected via telephone surveys with nominated supervisors and room leaders at baseline and immediately post-intervention. Secondary trial outcomes included the differences between groups in the number of serves consumed by children for each food group within the Australian Guide to Healthy Eating and in the proportion of children engaged in sedentary, walking or very active physical activity assessed via observation in a random subsample of 36 services at follow-up. There was no significant difference between groups for the primary trial outcome (p = 0.44). Relative to the control group, a significantly larger proportion of intervention group services reported having a written nutrition and physical activity policy (p = 0.05) and providing adult-guided activities to develop fundamental movement skills (p = 0.01). There were no significant differences between groups at follow-up on measures of child dietary intake or physical activity. The findings of the trial were equivocal. While there was no significant difference between groups for the primary trial outcome, the intervention did significantly increase the proportion of intervention group services implementing two of the seven healthy eating and physical activity policies and practices. High levels of implementation of a number of policies and practices at baseline, significant obesity prevention activity in the study region and higher than previously reported intra-class correlation of child behaviours may, in part, explain the trial findings.

The heritability of suicide is well established. Transmission of risk appears to follow traits more than disorders like depression. In the present project, we aimed at investigating the potential for transmission of cognitive deficits previously observed in suicide attempters, specifically impaired decision-making and cognitive control. Seventeen healthy first-degree relatives of suicide completers with no personal history of suicidal act were compared to 18 first-degree relatives of individuals with major depressive disorder but no family history of suicidal act, and 19 healthy controls. Decision-making was assessed with the Iowa Gambling Task, and cognitive control with the Stroop Task, the Hayling Sentence Completion Test, and the Trail-Making Test. Both suicide and depressed relatives showed lower gambling task net scores than healthy controls. However, there were trends toward lower learning abilities in suicide than depressed relatives (interaction: p = 0.07), with more risky choices at the end of the test. Suicide relatives also showed a higher number of self-corrected errors relative to the total number of errors in the Stroop colour test compared to both control groups, with no difference in interference scores. There was no group-difference for any other cognitive tests. Our findings suggest that decision-making impairment may be found in healthy relatives of suicides and represent a cognitive endophenotype of suicidal behaviour. Normal cognitive control (or self-corrected deficits) may protect relatives against suicidal acts. Impairments in value-based and control processes may, therefore, be part of the suicide vulnerability and represent potential targets of preventative interventions. Copyright © 2015 Elsevier Ltd.

Hypopituitarism is associated with lower oxytocin concentrations and reduced empathic ability.

PubMed

Central diabetes insipidus is characterised by arginine vasopressin deficiency. Oxytocin is structurally related to vasopressin and is synthesised in the same hypothalamic nuclei, thus we hypothesised that patients with acquired central diabetes insipidus and anterior hypopituitarism would display an oxytocin deficiency. Moreover, psychological research has demonstrated that oxytocin influences social and emotional behaviours, particularly empathic behaviour. We therefore further hypothesised that central diabetes insipidus patients would perform worse on empathy-related tasks, compared to age-matched and gender-matched clinical control (clinical control-isolated anterior hypopituitarism) and healthy control groups. Fifty-six participants (age 46.54 ± 16.30 yrs; central diabetes insipidus: n = 20, 8 males; clinical control: n = 15, 6 males; healthy control: n = 20, 7 males) provided two saliva samples which were analysed for oxytocin and completed two empathy tasks. Hypopituitary patients (both central diabetes insipidus and clinical control groups) had significantly lower oxytocin concentrations compared to healthy control participants. Hypopituitary patients also performed significantly worse on both the reading the mind in the eyes task and the facial expression recognition task compared to healthy control participants. Regression analyses further revealed that central diabetes insipidus patients' oxytocin concentrations significantly predicted their performance on easy items of the reading the mind in the eyes task. Hypopituitarism may therefore be associated with reduced oxytocin concentrations and impaired empathic ability. While further studies are needed to replicate these findings, our data suggest that oxytocin replacement may offer a therapeutic approach to improve psychological well-being in patients with hypopituitarism.

Deficiencies in social relationships of individuals with neurosis

Srivastava, Sunil

2006-01-01

Background: Social interaction and network of individuals with neurosis have been reported to be inadequate. Aim: To measure deficiencies in the social network of individuals with neurosis. Methods: Fifty consecutive patients with neurosis attending the OPD of the Department of Psychiatry, King George's Medical College, Lucknow, who were diagnosed as per the criteria of ICD-9, were included in the study. A control group of 40 healthy persons matched for age, sex, education and marital status was also taken. Interaction with the primary group (defined as consisting of all kin, nominated friends, work associates and neighbours) was measured by the Social Interaction Schedule of Henderson et al. as modified for the Indian population. Results: Patients reported significantly higher mean duration of unpleasant but affectively intense interaction with one person within or outside the primary group and affectively unpleasant and intense interaction with more than one person within or outside the primary group or affectively superficial but unpleasant interaction with one or more person of the primary group. Healthy subjects reported more of pleasant interaction with one person within or outside the primary group and affectively intense and pleasant interaction with more than one person within or outside the primary group or affectively superficial but pleasant interaction with one or more persons of the primary group; the difference was statistically significant as compared to patients with neurosis. Conclusion: The primary group of patients with neurosis was significantly smaller in numerical size as compared with that of controls and in terms of the total time spent with members of the primary group, patients with neurosis reported more interactions of unpleasant type and less of pleasant type as compared with healthy controls.

This study was designed to investigate the effects of manual lymph drainage on the cardiac autonomic tone. Thirty-two healthy male subjects were randomly assigned to manual lymph drainage (MLD) (experimental) and rest (control) groups. Electrocardiogram (ECG) parameters were recorded with bipolar electrocardiography using standard limb lead positions. The pressure-pain threshold (PPT) was quantitatively measured using an algometer. Heart rate variability differed significantly between the experimental and control groups (p < 0.05), but the PPT in the upper trapezius muscle did not (p > 0.05). These findings indicate that the application of MLD was effective in reducing the activity of the sympathetic nervous system.

Background: Neurological soft signs (NSS) are hypothesized as candidate endophenotypes for schizophrenia, but their prevalence and relations with clinical and demographic data are unknown. The authors undertook a quantification (meta-analysis) of the published literature on NSS in patients with schizophrenia and healthy controls. A systematic search was conducted for published articles reporting NSS and related data using standard measures in schizophrenia and healthy comparison groups. Method: A systematic search was conducted for published articles reporting data on the prevalence of NSS in schizophrenia using standard clinical rating scales and healthy comparison groups. Meta-analyses were performed using the Comprehensive Meta-analysis software package. Effect sizes (Cohen d) indexing the difference between schizophrenic patients and the healthy controls were calculated on the basis of reported statistics. Potential moderator variables evaluated included age of patient samples, level of education, sample sex proportions, medication doses, and negative and positive symptoms. Results: A total of 33 articles met inclusion criteria for the meta-analysis. A large and reliable group difference (Cohen d) indicated that, on average, a majority of patients (73%) perform outside the range of healthy subjects on aggregate NSS measures. Cognitive performance and positive and negative symptoms share 2%–10% of their variance with NSS. Conclusions: NSS occur in a majority of the schizophrenia patient population and are largely distinct from symptomatic and cognitive features of the illness. PMID:19377058

Brain derived neurotrophic factor (BDNF) and physical inactivity contribute to the development of metabolic syndrome (MetS). Aerobic training has been reported to improve MetS, however less attention has been directed toward the role of training and detraining on cognitive function in MetS. Twenty one healthy middle-aged males and 21 with MetS were distributed into four groups: MetS exercise (ME), MetS control (MC), Healthy exercise (HE) and healthy control (HC). Both ME and HE, followed a 6-week aerobic training program (3 sessions/week). Digit Span memory test and blood sampling were conducted pre training, post training and also following a six weeks detraining. Data were analyzed using spearman, pearson and repeated measure ANOVA tests. Baseline serum BDNF level was positively correlated with waist circumference (r=0.383, P=0.012) and showed significant elevation in MetS compared with healthy subjects (1101.66±61.34 vs. 903.72±46.57 pg/mL, P=0.014). After aerobic exercise BDNF level significantly increased in HE, but decreased in ME group (P=0.001). Both short and mid term memory significantly increased (P<0.05) only in HE group. Exercise induced cognitive improvement might be mediated via BDNF-linked mechanisms in healthy people. However, the health status of individuals should be considered.

To investigate the effects of wheelchair propulsion on neuropathic pain and to examine resting electroencephalography pre- and post-wheelchair propulsion after spinal cord injury. Cross-sectional study. Eleven individuals with spinal cord injury and pain and 10 healthy controls. Single-session 15-min wheelchair propulsion and measurement of resting electroence-phalography. Effects of wheelchair propulsion were investigated using numerical rating scale (NRS) for neuropathic pain and short-form Profile of Mood States-Brief for mood. Peak alpha frequency on electroencephalography was calculated in 4 regions of interest; frontal, central, parietal and occipital areas. These outcomes were compared between pre- and post-wheelchair propulsion. Ten participants with spinal cord injury and all healthy controls completed the wheelchair propulsion exercise. NRS scores and negative mood were significantly improved following the wheelchair propulsion exercise. Pre-wheelchair propulsion, parietal and occipital peak alpha frequencies were significantly lower in the spinal cord injury group compared with the healthy controls group. Post-wheelchair propulsion, central peak alpha frequency increased in the spinal cord injury group. Wheelchair propulsion exercise temporarily decreased neuropathic pain intensity, improved negative mood, and modified alpha activity in spinal cord injury.

The purpose of this study is to determine the metal content of alveolar macrophages by PIXE from 94 subjects divided into two groups as follows: group (1) — subjects with non-occupational exposure to industrial dust: 30 healthy volunteers (controls), 16 patients suffering from lung cancer; group (2) — 48 healthy steel workers from the Liège area (blast-furnace [ n=29] and coke oven [ n=19]). We hope to define more precisely the influence of carcinoma, smoking habit, pathology and occupational exposure in the steel industry on the macrophage metal content. This study has shown: (a) an Fe and Sr increase and a Br decrease in the macrophages of smokers (especially in heavy smokers): (b) a significant Fe, Ti, Br and Cu increase and a trend to Pb, Cr, As and Sr increase in macrophages of healthy steel workers (especially blast-furnace workers) in comparison with non-exposed controls; (c) a significant Fe, Br, Cu and Zn increase and a trend to Pb, As and Ni increase in macrophages of non-exposed patients with lung cancer by comparison with non-exposed controls. The mechanism of metal change could be explained by professional exposure and endogenous changes (protein synthesis, inflammation, bronchial bleeding, …)

This study investigated the association between plasma galanin level and depression severity. The severity of depression symptoms of 79 patients with major depressive disorder (MDD; 52 women and 27 men, 71 patients in onset, 8 in remission) was assessed using the 17-item Hamilton Depression Rating Scale. Venous fasting blood samples (5 mL) were taken from the 79 MDD patients, 35 healthy siblings, and 19 healthy controls, and plasma samples were prepared. Galanin levels in the plasma were measured by radioimmunoassay. Plasma galanin in MDD patients was significantly higher than that of remission patients, healthy siblings, or healthy controls (P < 0.05) There was no significant difference between the healthy sibling and healthy control groups (P = 0.924). Plasma galanin of remission patients was also significantly higher than that of healthy controls (P < 0.05). There was no significant correlation between age and galanin levels in the 79 patients (r = 0.053, P = 0.646), nor was there a correlation between age and galanin levels when patients were stratified by gender (P > 0.05). There was a significant positive correlation between plasma galanin levels and depression severity in women MDD patients (r = 0.329, df = 42, P = 0.020), but not in men patients. Plasma galanin levels may be an important biomarker for depression severity, especially in female patients.

Background/Aims Few obesity prevention trials have focused on young children and their families in the home environment, particularly in underserved communities. Healthy Children, Strong Families 2 is a randomized controlled trial of a healthy lifestyle intervention for American Indian children and their families, a group at very high risk of obesity. The study design resulted from our long-standing engagement with American Indian communities, and few collaborations of this type resulting in the development and implementation of a randomized clinical trial have been described. Methods Healthy Children, Strong Families 2 is a lifestyle intervention targeting increased fruit and vegetable intake, decreased sugar intake, increased physical activity, decreased TV/screen time, and two less-studied risk factors: stress and sleep. Families with young children from five American Indian communities nationwide were randomly assigned to a healthy lifestyle intervention ( Wellness Journey) augmented with social support (Facebook and text messaging) or a child safety control group ( Safety Journey) for 1 year. After Year 1, families in the Safety Journey receive the Wellness Journey, and families in the Wellness Journey start the Safety Journey with continued wellness-focused social support based on communities' request that all families receive the intervention. Primary (adult body mass index and child body mass index z-score) and secondary (health behaviors) outcomes are assessed after Year 1 with additional analyses planned after Year 2. Results To date, 450 adult/child dyads have been enrolled (100% target enrollment). Statistical analyses await trial completion in 2017. Lessons learned Conducting a community-partnered randomized controlled trial requires significant formative work, relationship building, and ongoing flexibility. At the communities' request, the study involved minimal exclusion criteria, focused on wellness rather than obesity, and included an active control group and a design allowing all families to receive the intervention. This collective effort took additional time but was critical to secure community engagement. Hiring and retaining qualified local site coordinators was a challenge but was strongly related to successful recruitment and retention of study families. Local infrastructure has also been critical to project success. Other challenges included geographic dispersion of study communities and providing appropriate incentives to retain families in a 2-year study. Conclusion This multisite intervention addresses key gaps regarding family/home-based approaches for obesity prevention in American Indian communities. Healthy Children, Strong Families 2's innovative aspects include substantial community input, inclusion of both traditional (diet/activity) and less-studied obesity risk factors (stress/sleep), measurement of both adult and child outcomes, social networking support for geographically dispersed households, and a community selected active control group. Our data will address a literature gap regarding multiple risk factors and their relationship to health outcomes in American Indian families.

Modern studies have indicated Gardenia jasminoides Ellis (G. jasminoides) showed positive effect in treating type 2 diabetes mellitus (T2DM). In this study, 60 streptozotocin-induced T2DM rats were divided into four groups: type 2 diabetes control group, geniposide-treated group, total iridoid glycosides-treated group, and crude extraction of gardenlae fructus-treated group. The other ten healthy rats were the healthy control group. During 12 weeks of treatment, rat's feces samples were collected for the metabolomics study based on mass spectrometry technique. On the basis of the fecal metabolomics method, 19 potential biomarkers were screened and their relative intensities in each group were compared. The results revealed G. jasminoides mainly regulated dysfunctions in phenylalanine metabolism, tryptophan metabolism, and secondary bile acid biosynthesis pathways induced by diabetes. The current study provides new insight for metabonomics methodology toward T2DM, and the results show that feces can preferably reflect the liver and intestines disorders.

The present study explored the ability to control familiarity-based information in a memory exclusion paradigm in healthy young, older adults, and early-stage DAT individuals. We compared the predictive power of memory exclusion performance to standard psychometric performance in discriminating between healthy aging and the earliest detectable form of DAT and between APOe4-present and APOe4-absent genotype in healthy control individuals. Participants responded “yes” to words that were previously semantically encoded, and “no” to other words. The number of targets and distractors on the read “distractor” list was manipulated to investigate the degree to which aging and DAT influence the ability to recollect specific details of study episodes in the face of distractor familiarity due to repetition. Memory exclusion performance (as reflected by d′) decreased across participant groups (young > healthy old control > very mild DAT). Logistic regression analyses showed that d′ increased the discriminative power for healthy older adults vs. very mild DAT individuals above and beyond standard psychometric measures. Memory exclusion d′ was also lower for healthy control individuals with APOe4 allele, compared to those without the APOe4 allele after partialing out baseline psychometric performance. Discussion focuses on the importance of attentional control systems in memory retrieval and the utility of the opposition paradigm for early discrimination between healthy and pathological aging.

Clinical assessment of auditory attention in patients with disorders of consciousness is often limited by motor impairment. Here, we employ intersubject correlations among electroencephalography responses to naturalistic speech in order to assay auditory attention among patients and healthy controls. Electroencephalographic data were recorded from 20 subjects with disorders of consciousness and 14 healthy controls during of two narrative audio stimuli, presented both forwards and time-reversed. Intersubject correlation of evoked electroencephalography signals were calculated, comparing responses of both groups to those of the healthy control subjects. This analysis was performed blinded and subsequently compared to the diagnostic status of each patient based on the Coma Recovery Scale-Revised. Subjects with disorders of consciousness exhibit significantly lower intersubject correlation than healthy controls during narrative speech. Additionally, while healthy subjects had higher intersubject correlation values in forwards versus backwards presentation, neural responses did not vary significantly with the direction of playback in subjects with disorders of consciousness. Increased intersubject correlation values in the backward speech condition were noted with improving disorder of consciousness diagnosis, both in cross-sectional analysis and in a subset of patients with longitudinal data. Intersubject correlation of neural responses to narrative speech audition differentiates healthy controls from patients and appears to index clinical diagnoses in disorders of consciousness.

Some patients with myofascial pain from temporomandibular disorders (TMD) report pain in extra-trigeminal body regions. Our aim was to distinguish TMD as regional musculoskeletal pain syndrome (n=23) from a widespread pain syndrome (FMS; n=18) based on patients' tender point scores, pain drawings and quantitative sensory testing (QST) profiles. Referenced to 18 age- and gender-matched healthy subjects significant group differences for cold, pressure and pinprick pain thresholds, suprathreshold pinprick sensitivity and mechanical detection thresholds were found. Pain sensitivity in TMD patients ranged between those of FMS patients and healthy controls. The group of TMD patients was inhomogeneous with respect to their tender point count with an insensitive group (n=12) resembling healthy controls and a sensitive TMD group (n=9) resembling FMS patients. Nevertheless sensitive TMD patients did not fulfil diagnostic criteria for FMS in regard to widespread pain as shown by their pain drawings. TMD subgroups did not differ with respect to psychological parameters. The sensitive subgroup was more sensitive compared to healthy controls and to insensitive TMD patients in regard to their QST profile over all test areas as well as to their tenderness over orofacial muscles and trigeminal foramina. However, sensitive TMD patients had a short pain duration arguing against a transition from TMD to FMS over time. Data rather suggest an overlap in pathophysiology with FMS, e.g. a disturbance of central pain processing, in this subgroup of TMD patients. Those patients could be identified on the basis of their tender point count as an easy practicable screening tool.

To investigate cognitive flexibility and task-related heart rate variability following moderately intense aerobic exercise and after watching a video in both children with ADHD and healthy controls. Using a cross-over design, participants completed cognitive assessments following exercise and a physically inactive control condition. Behavioral performance was assessed using the Alternate Uses task. Heart rate variability was recorded via electrocardiography during the cognitive task. The statistical analysis revealed that in comparison with the control condition, both groups showed higher cognitive flexibility following aerobic exercise. Moreover, decreased low frequency and high frequency power was observed in the exercise condition. The findings suggest that exercise elicits similar benefits for cognitive flexibility in children with ADHD and healthy controls, partly due to an increase in arousal induced by parasympathetic withdrawal.

Reduced Risk-Taking After Prior Losses in Pathological Gamblers Under Treatment and Healthy Control Group but not in Problem Gamblers.

2018-06-01

A group of pathological gamblers and a group of problem gamblers (i.e., gamblers at risk of becoming pathological) were compared to healthy controls on their risk-taking propensity after prior losses. Each participant played both the Balloon Analogue Risk Taking task (BART) and a modified version of the same task, where individuals face five repeated predetermined early losses at the onset of the game. No significant difference in risk-taking was found between groups on the standard BART task, while significant differences emerged when comparing behaviors in the two tasks: both pathological gamblers and controls reduced their risk-taking tendency after prior losses in the modified BART compared to the standard BART, whereas problem gamblers showed no reduction in risk-taking after prior losses. We interpret these results as a sign of a reduced sensitivity to negative feedback in problem gamblers which might contribute to explain their loss-chasing tendency.

Previous studies have shown that mindfulness meditation may improve well-being in healthy individuals and be effective in the treatment of mental and neurological disorders. Here, we investigated the effects of an 8-week mindfulness-mediation program on the personality profiles of three groups of healthy individuals with no previous experience with meditation as compared to a control group not enrolled in any training. Personality profiles were obtained through the Temperament and Character Inventory (Cloninger et al., 1993). In the experimental groups, significant increments after the training were obtained in all the three character scales describing the levels of self maturity at the intrapersonal (Self-Directedness), interpersonal (Cooperativeness), and transpersonal (Self-Transcendence) levels. No changes were found in the control group. Strikingly, these effects were significant only in those groups who were engaged in consistent daily meditation practice but not in the group who attended the meditation training but were less consistent in home practice. Since higher scores in the character scales are associated to a lower risk of personality disorder, we propose that the increase of self maturity after the training may be an important mechanism for the effectiveness of mindfulness-oriented meditation in psychotherapeutic contexts.

This study aimed to determine the effect mobile messaging apps on coronary artery disease patient knowledge of and adherence to a healthy lifestyle. Due to the increasing incidence of coronary artery disease in recent years, interventions targeting coronary artery disease risk factors are urgent public priorities. The use of mobile technology in healthcare services and medical education is relatively new with promising future prospects. This study used a quasi-experimental design that included pre- and post-test for intervention and control groups. The study was conducted from January to April 2017 with both intervention and control group, in a teaching hospital in Klang Valley. Convenience sampling was used with inclusive criteria in choosing the 94 patients with coronary artery disease (intervention group: 47 patients; control group: 47 patients). The pre-test was conducted as a baseline measurement for both groups before they were given standard care from a hospital. However, only the intervention group was given a daily information update via WhatsApp for one month. After one month, both groups were assessed with a post-test. The split-plot ANOVA analysis indicates that there is a significant and positive effect of the intervention on coronary artery disease patients' knowledge on CAD risk factors [F(1, 92) = 168.15, p < .001] with a large effect size (η p 2 = .65). The mobile messaging apps also significantly improve the patients' adherence to a healthy lifestyle [F(1, 92) = 83.75, p < .001] with a large effect size (η p 2 = .48). This study concluded that WhatsApp was an effective health intervention in increasing coronary artery disease patient's knowledge and subsequently increasing their adherence to healthy lifestyles. In clinical setting, mobile messaging apps is useful in information delivery and efficient patient monitory. This article is protected by copyright. All rights reserved.

Crohn's disease (CD) is associated with intestinal dysbiosis, altered blood T cell populations, elevated faecal calprotectin (FC) and increased intestinal permeability (IP). CD-associated features present in siblings (increased risk of CD) but not in healthy controls, provide insight into early CD pathogenesis. We aimed to (1) Delineate the genetic, immune and microbiological profile of patients with CD, their siblings and controls and (2) Determine which factors discriminate between groups. Faecal microbiology was analysed by quantitative PCR targeting 16S ribosomal RNA, FC by ELISA, blood T cell phenotype by flow cytometry and IP by differential lactulose-rhamnose absorption in 22 patients with inactive CD, 21 of their healthy siblings and 25 controls. Subject's genotype relative risk was determined by Illumina Immuno BeadChip. Strikingly, siblings shared aspects of intestinal dysbiosis with patients with CD (lower concentrations of Faecalibacterium prausnitzii (p=0.048), Clostridia cluster IV (p=0.003) and Roseburia spp. (p=0.09) compared with controls). As in CD, siblings demonstrated a predominance of memory T cells (p=0.002) and elevated naïve CD4 T cell β7 integrin expression (p=0.01) compared with controls. FC was elevated (>50 μg/g) in 8/21 (38%) siblings compared with 2/25 (8%) controls (p=0.028); whereas IP did not differ between siblings and controls. Discriminant function analysis determined that combinations of these factors significantly discriminated between groups (χ(2)=80.4, df=20, p<0.001). Siblings were separated from controls by immunological and microbiological variables.

Asthma often complicates pregnancy and represents a risk of serious pregnancy complications. The complement system contributes to asthma pathogenesis and is up-regulated in healthy gestation as well. The anaphylatoxin C5a has a major pro-inflammatory role, and the complement factor H is a main soluble regulator protein both in asthma and during pregnancy; however, peripheral levels of these complement factors and their relationship to disease control have not yet been evaluated in pregnant subjects with asthma. The present study aimed to investigate circulating C5a and complement factor H levels in asthma (non-pregnant subjects with asthma; n = 19) and in pregnancy with asthma (pregnant subjects with asthma; n = 22), compared with healthy non-pregnant (n = 21) and healthy pregnant women (n = 13) and to test their relationship to clinical parameters of asthma (lung function, airway inflammation, and symptoms). Circulating C5a levels were higher in the pregnant asthma subject group compared with the healthy non-pregnant, healthy pregnant, and non-pregnant asthma groups: median 2.629 (interquartile range [IQR] 2.257-3.052) ng/mL versus 1.84 (IQR 1.576-2.563), 1.783 (IQR 0.6064-2.786), and 2.024 (IQR 1.232-2.615) ng/mL, respectively (P = .02 in all cases). C5a correlated negatively with FEV1 (r = -0.44, P = .039) and FVC values (r = -0.64, P = .001) in the pregnant asthma group and positively with fraction of exhaled nitric oxide levels in the non-pregnant asthma group (n = 12, r = 0.78, P = .004). Complement factor H levels were elevated in both the healthy pregnant and pregnant asthma subject groups compared with the healthy non-pregnant group (median 1,082 [IQR 734.9-1,224] and 910.7 [IQR 614.5-1076] μg/mL vs. 559.7 [IQR 388.7-783.1] μg/mL, P = .002 and P = .004, respectively) but not in the pregnant asthma group compared with the non-pregnant asthma group (median 687.4 [IQR 441.6-947.6] μg/mL, P = .10). Asthma during pregnancy increases the circulating level of pro-inflammatory C5a, which is accompanied by impaired lung function and partly counteracted by the gestation-specific elevation of regulatory complement factor H level (detected in pregnancy both in healthy and subjects with asthma).

Only few studies have compared the frequency of traumatic life events during childhood in inpatients with depression with a healthy control group. Consecutively admitted inpatients with depression (n = 79), most of whom belonged to the melancholic subtype (n = 73; 92.4%), and healthy controls (n = 110) were investigated using a comprehensive retrospective interview with 203 questions regarding childhood traumatic life events, parental attitudes, family history of psychiatric disorders and birth risk factors. Depressed patients had significantly more severe traumatic events (mean score 1.33; SD 1.4) than control subjects (0.85; SD 1.2) on a 0-10 point "severe trauma scale". 70.9% (n = 56) of the depressed patients, but only 48.2% (n = 53) of the controls reported at least one severe traumatic event. When looking at single events, only few differences were found between patients and controls. Compared to controls, patients described significantly higher rates of psychiatric disorders in their families, in particular depression. Parental rearing styles were rated as more unfavorable in the patient group. In a logistic regression model, of all possible etiological factors examined, only a family history of psychiatric disorders showed a significant influence (OR = 3.6). Melancholic depression seems to be less associated with traumatic events than other psychiatric disorders.

The aim of this study was to assess the effectiveness of balance training with somatosensory and neurofeedback training on dynamic and static balance in healthy, elderly adults. The sample group consisted of 45 healthy adults randomly assigned to one of the three test groups: somatosensory, neurofeedback, and a control. Individualization of the balance program started with pre-tests for static and dynamic balances. Each group had 15- and 30-min training sessions. All groups were tested for static (postural stability) and dynamic balances (Berg Balance Scale) in acquisition and transfer tests (fall risk of stability and timed up and go). Improvements in static and dynamic balances were assessed by somatosensory and neurofeedback groups and then compared with the control group. Results indicated significant improvements in static and dynamic balances in both test groups in the acquisition test. Results revealed a significant improvement in the transfer test in the neurofeedback and somatosensory groups, in static and dynamic conditions, respectively. The findings suggest that these methods of balance training had a significant influence on balance. Both the methods are appropriate to prevent falling in adults. Neurofeedback training helped the participants to learn static balance, while somatosensory training was effective on dynamic balance learning. Further research is needed to assess the effects of longer and discontinuous stimulation with somatosensory and neurofeedback training on balance in elderly adults.

Panic disorder refers to the frequent and recurring acute attacks of anxiety. Objective: This study describes the routine use of mobiles phones (MPs) and investigates the appearance of possible emotional alterations or symptoms related to their use in patients with panic disorder (PD). Background: We compared patients with PD and agoraphobia being treated at the Panic and Respiration Laboratory of The Institute of Psychiatry, Federal University of Rio de Janeiro, Brazil, to a control group of healthy volunteers. Methods: An MP-use questionnaire was administered to a consecutive sample of 50 patients and 70 controls. Results: People with PD showed significant increases in anxiety, tachycardia, respiratory alterations, trembling, perspiration, panic, fear and depression related to the lack of an MP compared to the control group. Conclusions: Both groups exhibited dependence on and were comforted by having an MP; however, people with PD and agoraphobia showed significantly more emotional alterations as well as intense physical and psychological symptoms when they were apart from or unable to use an MP compared to healthy volunteers.
