    The aims of this study were to determine if quality of life (QOL) among Arab Muslim hematopoietic stem cell transplantation (HSCT) survivors differs from that of a healthy matched comparison group and to examine the relationships of demographic and medical variables and perceived social support with post-HSCT QOL. HSCT survivors (n = 63) were recruited from the King Hussein Cancer Center outpatient clinic. A matched (age, gender, education), healthy comparison group (n = 63) was recruited through public advertisements. Participants completed the EORTC-30 QOL scale and the Medical Outcomes Study Social Support Survey. Differences were found between the Arab Muslim HSCT survivor and healthy comparison groups for physical functioning (p Western HSCT survivors in the social and emotional QOL domains. Given growing numbers of Arab and Muslim cancer survivors in the USA and other Western countries, future research is warranted.

    Analysis of changes in self-perception in post-mastectomy patients and its comparison with self-perception of healthy women. The subjects of this study were 50 women. The main group was post-mastectomy patients involved in the meetings of the Amazons Club (25 women). The reference group consisted of 25 healthy women. The method used in the study was the ACL (Adjective Check List) test, identifying 37 dimensions of self-image. Oncological patients completed a test twice (for current and pre-cancer self-image), and healthy women once - for current self. Both groups were selected similarly in respect of education level for the purpose of ensuring a similar level of insight. Retrospective self-image and the current one in the Amazon women group were highly convergent. Existing differences include a reduced need for achievement and dominance, and a lower level of self-confidence. However, the comparison of current self-images in both groups showed a large discrepancy of the results. The Amazon women assess themselves in a much more negative way. Also, their self-image is self-contradictory in certain characteristics. Mastectomy is a difficult experience requiring one to re-adapt and to accept oneself thereafter. The way of thinking about oneself is a defence mechanism helping to cope. The work with patients programmes must, therefore, focus on identifying their emotions and thoughts, especially on those they do not want to accept because of the perceived pressure from the environment to effectively and quickly deal with this difficult situation. The increasing acceptance of personal limitations may help the affected women to adjust psychologically faster and easier.

    Full Text Available The aim of the study was to compare static postural balance of healthy individuals of three age groups in different conditions of support and vision. Seventy one individuals, divided into 3 groups, were analyzed: young group (YG: 22.2 ± 2.1 years, middle aged group (MAG: 50.7 ± 5.7 years and older individuals group (EG: 66.8 ± 5.4 years. Their balance was tested on a force platform, under 3 support and 3 visual conditions. Measures included: total (TD, anterior-posterior (APD and mediolateral displacement (MLD of the center of pressure (CoP. ANOVA revealed significant differences for interactions between group X support conditions and group X visual conditions for the 3 variables (p<0.01, with greater displacements for the MAG and EG groups during single-leg stance with partial and occluded vision (p<0.05. Static postural balance decreased over time in healthy individuals, and conditions of support and visual negatively affected balance with the increment of age.

    Drug abuse and its consequences are major health problems in Middle-East countries such as Iran. Salesmen and smugglers may add lead to opium during the process of opium preparation to increase the weight of opium for more profit. Several reports have found lead poisoning symptoms in opium addicted patients and there are many nonspecific symptoms mimicking lead poisoning in opium addicted patients. As far as the literature review is concerned, there is no comparative study about blood lead level (BLL) in addicted patients with healthy controls. Therefore, it seems evaluation of blood lead level in opium addicted patients to be important. In this study, the BLL of forty-four subjects in two patient and control groups was evaluated. The patient group (22 subjects) was comprised of patients who used oral opium. Control group (22 subjects) was matched with the patient group for age and sex, considering inclusion and exclusion criteria with a mean age of 38.8+/-6.7. For blood lead assay, 3 mL of whole blood was obtained from both groups by venipuncture and BLL was assessed immediately using an atomic absorption spectrophotometer. The BLL in patient group had a range of 7.2 to 69.9 g/dL with a mean of 21.9+/-13.2. In the healthy control group, BLL was between 4.1 to 17.4 g/dL with a mean of 8.6+/-3.5. The mean difference of both groups (t=4.56) was statistically significant (Popium ingested (r=0.65, Popium ingestion in the patient group. It would be concluded that opium addicts have an elevated BLL compared to healthy controls. Therefore, screening of blood lead concentration is helpful for opium addicted people especially with non-specific symptoms. In this regard, a similar investigation with a larger sample size of opium addicted patients (including both oral and inhaled) and a control group is suggested to confirm the findings of this research.

    To determine the features and use of groups related to healthy eating on Facebook. We carried out a cross-sectional study through the Internet. Using the API on Facebook, we included open groups related to healthy eating in the Spanish language. The variables studied were name, description, category, the number and gender of users, date of creation, number of posts, content of the first 20 posts, and the most recent update. We selected 281 open groups for inclusion in the study. Of these, 125 were excluded because the content was unrelated to healthy eating. Finally 156 groups were studied with 14,619 users (10,373 women [71%] and 3,919 men [26.8%]). Dietary products were promoted by 40% of the groups. Facebook is used as a means of communication and for sharing health information. Because many of these groups promote dietary products, their usefulness for health education is doubtful. Health organizations should participate in social media. Copyright © 2012 SESPAS. Published by Elsevier Espana. All rights reserved.

    According to the cognitive model, the common mechanism underlying all psychological disorders is distorted or dysfunctional thoughts that affect mood and behaviors. Dysfunctional thoughts predispose an individual to depression and are among the processes that form the basis of personality traits. Elucidating the personality beliefs associated with depression and dysfunctional thoughts is important to understanding and treating depression. The aim of the present study is to determine whether depressed patients exhibited pathological personality beliefs compared with healthy controls. Furthermore, we investigated which personality beliefs were more common among such depressed patients. A total of 70 patients who were admitted to the Department of Psychiatry at Ankara Diskapi Yildirim Beyazit Training and Research Hospital (Ankara, Turkey) and diagnosed with major depressive disorder according to The Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) diagnostic criteria were included in the study. Additionally, 70 healthy controls matched for age, marital status, and education were included in the study. The Sociodemographic Data Form and Personality Belief Questionnaire-Short form (PBQ-SF) were administered to the participants. A comparison of the depression group with the healthy controls revealed higher scores in dependent, passive-aggressive, obsessive-compulsive, antisocial, histrionic, paranoid, borderline, and avoidant personality subscales in the depressive group. These results suggest that personality beliefs at the pathological level are more common in depressive patients and that the detection of these beliefs would be useful for predicting the prognosis of the disease and determining appropriate treatment methods.

    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.

    This meta-analysis integrates results from 330 studies on differences between body image of children and adolescents with and without chronic physical illness. Young people with a chronic illness had a less positive body image than their healthy peers although the average size of differences was small (g=-.30 standard deviation units). A comparison of diseases showed that young people with obesity (g=-.79), cystic fibrosis (g=-.50), scoliosis (g=-.41), asthma (g=-.37), growth hormone deficits (g=-.35), spina bifida (g=-.23), cancer (g=-.20), and diabetes (g=-.17) evaluated their body less positively than their healthy peers. Furthermore, levels of body dissatisfaction varied by age at onset of the disease, method for assessing body image, ethnicity, year of publication, and comparison group. Recommendations are stated for reducing effects of chronic illness on the body image of people with chronic illness. Copyright © 2012 Elsevier Ltd. All rights reserved.

    An incomparably useful examination of statistical methods for comparisonThe nature of doing science, be it natural or social, inevitably calls for comparison. Statistical methods are at the heart of such comparison, for they not only help us gain understanding of the world around us but often define how our research is to be carried out. The need to compare between groups is best exemplified by experiments, which have clearly defined statistical methods. However, true experiments are not always possible. What complicates the matter more is a great deal of diversity in factors that are not inde

    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.

    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.

    Patients with schizophrenia may have sleep disorders even when clinically stable under antipsychotic treatments. To better understand this issue, we measured sleep characteristics between 1999 and 2003 in 150 outpatients diagnosed with Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) schizophrenia or schizoaffective disorder and 80 healthy controls using a sleep habits questionnaire. Comparisons between both groups were performed and multiple comparisons were Bonferroni corrected. Compared to healthy controls, patients with schizophrenia reported significantly increased sleep latency, time in bed, total sleep time and frequency of naps during weekdays and weekends along with normal sleep efficiency, sleep satisfaction, and feeling of restfulness in the morning. In conclusion, sleep-onset insomnia is a major, enduring disorder in middle-aged, non-hospitalized patients with schizophrenia that are otherwise clinically stable under antipsychotic and adjuvant medications. Noteworthy, these patients do not complain of sleep-maintenance insomnia but report increased sleep propensity and normal sleep satisfaction. These results may reflect circadian disturbances in schizophrenia, but objective laboratory investigations are needed to confirm subjective sleep reports. Copyright © 2009 Elsevier Ltd.

    Prevalence of allergies is different around the world. Allergic rhinitis is a common chronic disease in children. Intelligence quotient (IQ) is an indicator of efficacy and many factors including chronic diseases may affect it. This study compares the IQs of children diagnosed with persistent or perennial allergic rhinitis with healthy children. This was a comparative study that was conducted from June 2011-May 2013 in an academic referral clinic. In this study, 90 patients aged 6- to 14-yearsold who were diagnosed with persistent or perennial allergic rhinitis and were compared to 90 age and gender match healthy patients from their respective families. The Wechsler Intelligence Scale for Children was used to divide and calculate overall IQ, verbal IQ, and practical IQ. The t-test and chi square were used to analyze quantitative variables and qualitative variables, respectively. In this study, out of total 180 children, 90 (50%) in the case group and 90 children (50%), the control group participated for IQ comparison. One hundred (57%) were male and 80 (43%) were female. The overall IQ for allergic rhinitis patients and healthy patients was 109.2 and 107.5, respectively. This difference was not considered significant. Furthermore, there was no significant difference between the IQ scores of males and females. Although allergic rhinitis is a chronic disease and effects quality of life, there were no identifiable negative effects on IQ.

    The aging of the population is a universal phenomenon with direct consequences upon the public health system. One of the main repercussions of the growth in this sector of the population is the increased prevalence of disorders such as dementia and depression which are very frequent among the elderly. The relationship between cardiovascular risk factors, dementia and depression have been addressed in many recent investigations. Objectives To evaluate the relationship of cognitive performance and depressive symptoms with cardiovascular risk in the elderly. Methods 94 high cardiovascular risk elderly patients and 160 healthy community elderly were evaluated cross-sectionally. The Mini Mental State Examination (MMSE) and the Geriatric Depression Scale (GDS-15) were used as the main measures. The cutoff for presence of depression was 6 on the GDS. Results The high cardiovascular risk elderly group showed significantly lower scores on the MMSE (p<0.001) and was significantly associated to depression (p<0.001), independently of education. The logistic regression analysis for depression as the dependent variable, age and group (healthy community or high cardiovascular risk elderly) were kept in the final equation. Higher age (Odds Ratio=0.92; 95% CI 0.86–0.98) and high cardiovascular risk elderly (OR=2.99; 95% CI 1.36–6.59) were associated to depression. Conclusions The present findings corroborate the different cognitive performance of elderly with high cardiovascular risk factors and the association of depressive symptoms with this group.

    Full Text Available An ultrastructural comparison between the nasal cavities of healthy rabbits and those suffering from two forms of spontaneous infection with Pasteurella multocida was undertaken. Twelve commercially produced rabbits of different ages and respiratory health status were divided into four groups: healthy from 0 to 21 days (G1, n=2; healthy from 23 to 49 days (G2, n=2; healthy from 51 to 69 days (G3, n=2; diseased rabbits with septicemia and the rhinitic form of P. multocida infection (G4, n=3. The main ultrastructural changes observed were a widening of the interepithelial spaces, increased activity and number of goblet cells, the formation of two types of vacuoles in epithelial cells, the degranulation and migration of heterophils between the epithelial cells, and the association of this migration with some of the other changes. No bacteria were observed adhering to the epithelium, and very few were observed free in the mucus. Scant inter-epithelial spaces were found in healthy rabbits, but they were not as large and numerous as those found in diseased animals. We discuss the origin and meaning of these changes but, we focus on the significance of the inter-epithelial spaces and goblet cells for the defense of the upper respiratory airways against the bacterium and its lipopolysaccharide.

    This study aimed to explore differences between mothers with healthy weight versus overweight/obesity in a wide range of their reported child feeding practices and their reports of their children's eating behaviours. Mothers (N = 437) with a 2-6-year-old child participated. They comprised two groups, based on their BMI: healthy weight (BMI of 18.0-24.9, inclusive) or overweight/obese (BMI of 25.0 or more). All mothers provided demographic information and completed self-report measures of their child feeding practices and their child's eating behaviour. In comparison to mothers with healthy weight, mothers with overweight/obesity reported giving their child more control around eating (p obesity reported their children to have a greater desire for drinks (p = 0.003), be more responsive to satiety (p = 0.007), and be slower eaters (p = 0.034). Mothers with overweight/obesity appear to engage in generally less healthy feeding practices with their children than mothers with healthy weight, and mothers with overweight/obesity perceive their children as more avoidant about food but not drinks. Such findings are likely to inform future intervention developments and help health workers and clinicians to better support mothers with overweight/obesity with implementing healthful feeding practices and promoting healthy eating habits in their children.

    A program called ``Innovative Billing?? has been developed to provide individualized energy information for a mass audience?the entireresidential customer base of an electric or gas utility. Customers receive a graph on the bill that compares that customer?s consumption with othersimilar customers for the same month. The program aims to stimulate customers to make ef?ciency improvements. To group as many as severalmillion customers into small ``comparison groups??, an automated method must be developed drawing solely from the data available to the utility.This paper develops and applies methods to compare the quality of resulting comparison groups.A data base of 114,000 customers from a utility billing system was used to evaluate Innovative Billing comparison groups, comparing fouralternative criteria: house characteristics (?oor area, housing type, and heating fuel); street; meter read route; billing cycle. Also, customers wereinterviewed to see what forms of comparison graphs made most sense and led to fewest errors of interpretation. We ?nd that good qualitycomparison groups result from using street name, meter book, or multiple house characteristics. Other criteria we tested, such as entire cycle, entiremeter book, or single house characteristics such as ?oor area, resulted in poor quality comparison groups. This analysis provides a basis forchoosing comparison groups based on extensive user testing and statistical analysis. The result is a practical set of guidelines that can be used toimplement realistic, inexpensive innovative billing for the entire customer base of an electric or gas utility.

    Resilience is essential for the psychological adjustment of adolescents experiencing difficulty. Comparing differences in resilience between adolescent survivors of brain tumors and healthy adolescents may help identify factors related to resilience in adolescents. The purpose of this study was to clarify how illness impacts the normative development of adolescent survivors of brain tumors by comparing them to healthy adolescents in terms of resilience and how it is affected by various health problems. This cross-sectional, case-control study used convenience sampling to recruit 13- to 18-year-old adolescent survivors of brain tumors and healthy adolescents matched by school level, gender, and living area. Data were collected by structured questionnaires. The sample included 60 adolescent survivors and 120 healthy adolescents. Participants in both groups were predominantly male adolescents (63.3%) and junior high school students (55%). The 2 groups did not differ significantly in resilience, but survivors without emotional problems had a higher mean resilience score than did healthy adolescents and survivors with emotional problems (F = 8.65, P adolescent survivors of brain tumors and healthy adolescents. In addition, the impact of emotional problems on resilience was more severe in brain tumor survivors than in healthy adolescents. Our results suggest that pediatric oncology nurses design interdisciplinary school-based interventions to reduce the impact of emotional problems on resilience in both healthy adolescents and those who survived brain tumors.

    This paper describes the psychomotor and mnesic effects of single oral doses of etifoxine (50 and 100 mg) and lorazepam (2 mg) in healthy subjects. Forty-eight healthy subjects were included in this randomized double blind, placebo controlled parallel group study [corrected]. The effects of drugs were assessed by using a battery of subjective and objective tests that explored mood and vigilance (Visual Analog Scale), attention (Barrage test), psychomotor performance (Choice Reaction Time) and memory (digit span, immediate and delayed free recall of a word list). Whereas vigilance, psychomotor performance and free recall were significantly impaired by lorazepam, neither dosage of etifoxine (50 and 100 mg) produced such effects. These results suggest that 50 and 100 mg single dose of etifoxine do not induce amnesia and sedation as compared to lorazepam.

    Behavioral disturbances and lack of empathy are distinctive clinical features of behavioral variant frontotemporal dementia (bvFTD) in comparison to Alzheimer disease (AD). The aim of this meta-analytic review was to compare facial emotion recognition performances of bvFTD with healthy controls and AD. The current meta-analysis included a total of 19 studies and involved comparisons of 288 individuals with bvFTD and 329 healthy controls and 162 bvFTD and 147 patients with AD. Facial emotion recognition was significantly impaired in bvFTD in comparison to the healthy controls (d = 1.81) and AD (d = 1.23). In bvFTD, recognition of negative emotions, especially anger (d = 1.48) and disgust (d = 1.41), were severely impaired. Emotion recognition was significantly impaired in bvFTD in comparison to AD in all emotions other than happiness. Impairment of emotion recognition is a relatively specific feature of bvFTD. Routine assessment of social-cognitive abilities including emotion recognition can be helpful in better differentiating between cortical dementias such as bvFTD and AD. © The Author(s) 2016.

    The purpose of this study is to validate the use of MR spectroscopy (MRS) in measuring muscular fat and to compare it with T2 maps in differentiating boys with Duchenne muscular dystrophy (DMD) from healthy boys. Forty-two boys with DMD and 31 healthy boys were evaluated with MRI with (1)H-MRS and T2 maps. Grading of muscle fat and edema on conventional images, calculation of fat fractions ([fat / fat] + water) on MRS, and calculation of T2 fat values on T2 maps of the gluteus maximus and vastus lateralis muscles were performed. Group comparisons were made. The 95% reference interval (RI) of fat fraction for the control group was applied and compared with T2 map results. Minimal fat on T1-weighted images was seen in 90.3% (gluteus maximus) and 71.0% (vastus lateralis) of healthy boys, versus 33.3% (gluteus maximus) and 52.4% (vastus lateralis) of boys with DMD. Muscle edema was seen in none of the healthy boys versus 52.4% (gluteus maximus) and 57.1% (vastus lateralis) of the boys with DMD. Fat fractions were higher in the DMD group (52.7%, gluteus maximus; 27.3%, vastus lateralis) than in the control group (12.8%, gluteus maximus; 13.7%, vastus lateralis) (p muscle edema in DMD.

    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.

    Full Text Available The article presents the results of the research conducted in December 2013 at the Peoples’ Friendship University of Russia with the method of focus groups. The study aimed at identification not only the differences in understanding healthy lifestyles among students and their attitudes to a healthy lifestyle, but also its components, obstacles for the realization and opportunities to overcome them. The focus group research was just another stage of the project aimed at studying health and healthy lifestyles as values and the characteristics of the formation and manifestation of a health-preserving behavior. Despite many opportunities to motivate a health-preserving behavior among students, we still see obstacles for its formation due to both social and cultural characteristics. The study revealed that the value of health at this stage of life is rather declarative: only a small percentage of respondents are fully aware of the necessity of a health-preserving behavior and do really adopt a healthy lifestyle. The basic factors influencing the formation of the healthy lifestyle among the youth are the family, social environment and mass media. The respondents, in particular, confirm the significant impact of their social circle on the commitment to the bad habits as well as to healthy hobbies. The main factors hindering the healthy lifestyles among students include lack of free time, welfare, Internet addiction, lack of sufficient motivation and self-organization.

    Despite national attention to the childhood obesity epidemic, there are few US-based studies that directly ask children--especially children from low-income families and from multiple racial/ethnic groups--why they do or do not engage in healthy eating behaviors. The purpose of this study was to identify motivators of and barriers to healthy eating behaviors, as reported by black, Hispanic, and white children from low-income families. Six gender- and race/ethnicity-concordant focus groups were conducted with 37 children who were aged 9 to 12 years and from families with an annual household income of $40000 or less. Multiple strategies were used to employ a culturally sensitive approach to both data collection and data analysis (eg, a team of culturally diverse researchers utilized inductive qualitative analysis to analyze focus group transcripts). The motivators of and barriers to healthy eating behaviors most commonly reported across the 6 focus groups included social influence, taste, issues of availability, weight concerns, and the desire to be healthy. A variety of less commonly reported motivators and barriers were also discussed. Findings were generally similar across gender and race/ethnicity. Children in this age range can indeed identify a variety of motivators and barriers that influence their engagement in healthy eating behaviors. Interventions targeting obesity and eating behaviors should include an assessment of children's own perceived motivators of and barriers to healthy eating.

    Full Text Available Introduction. Given the high prevalence of childhood obesity in the United States, we aimed to investigate youth's understanding of obesity and to investigate gaps between their nutritional knowledge, dietary habits, and perceived susceptibility to obesity and its co-morbidities. Methods. A marketing firm contracted by Children's Healthcare of Atlanta facilitated a series of focus group discussions (FGD to test potential concepts and sample ads for the development of an obesity awareness campaign. Data were collected in August and September of 2010 with both overweight and healthy weight 4th-5th grade and 7th-8th grade students. We conducted a secondary analysis of the qualitative FGD transcripts using inductive thematic coding to identify key themes related to youth reports of family eating habits (including food preparation, meal frequency, and eating environment, perceived facilitators and barriers of healthy diet, and knowledge about obesity and its complications. Results. Across focus group discussions, mixed attitudes about healthy eating, low perceived risk of being or becoming obese, and limited knowledge about the health consequences of obesity may contribute to the rising prevalence of obesity among youth in Georgia. Most youth were aware that obesity was a problem; yet most overweight youth felt that their weight was healthy and attributed overweight to genetics or slow metabolism. Conclusions. Our analysis suggests that urban youth in Georgia commonly recognize obesity as a problem, but there is less understanding of the link to lifestyle choices or the connection to future morbidities, suggesting a need for education to connect lifestyle behaviors to development of obesity.

    The aim of this study was to standardize and investigate the changes in corneal clarity with age. Densitometry software for the Oculus Pentacam was used to examine corneal clarity at different age groups.A total of 192 eyes from 97 healthy participants were included in this cohort comparative nonrandomized, cross-sectional study. An Oculus Pentcam was used to image the cornea of healthy participants grouped by age (between 10 and 70 years old). Data from the densitometry output have been used to determine clarity in concentric zones and different depths of the cornea.Corneal densitometry (CD) across all ages showed significant differences between groups when divided into the following layers: anterior, central, and posterior or divided into 0 to 2, 2 to 6, and 6 to 10 mm concentric zones (P age in all 3 layers of the periphery (6-10 mm) (P age group had lower clarity than the 20 to 30-age group (P age is differed when the cornea is divided into layers and zones.

    Group-based psychosocial programs provide an effective forum for improving mood and social support for cancer patients. Because some studies show more benefit for patients with initially high psychosocial distress, and little or no benefit for patients with initially low distress, support programs may better address patient needs by only including distressed patients. However, distressed patients may benefit particularly from the presence of nondistressed patients who model effective coping, an idea many researchers and extensions of social comparison theory support. We present a theoretical analysis, based on a social comparison perspective, of how group composition (heterogeneous group of distressed and nondistressed patients versus homogeneous group of distressed patients) may affect the efficacy of cancer support programs. We propose that a heterogeneous group allows distressed patients maximal opportunity for the various social comparison activities they are likely to prefer; a homogeneous group does not. Though the presence of nondistressed patients in a heterogeneous group potentially benefits distressed patients, the benefits for nondistressed patients are unclear. For nondistressed patients, heterogeneous groups may provide limited opportunities for preferred social comparison activity and may create the possibility for no benefit or even negative effects on quality of life. We also discuss ethical issues with enrolling nondistressed patients whose presence may help others, but whose likelihood of personal benefit is questionable.

    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.

    The current literature on determinants of behavior change in weight management lacks sufficient studies on type of motivation among children/adolescents, on perceived competence, and in relation to healthy eating. This study aimed to investigate type of motivation and levels of perceived competence for healthy diet and exercise, as well as general self efficacy among adolescents. We hypothesized that overweight/obese adolescents would demonstrate lower autonomous motivation and perceived competence regarding diet and exercise, and lower self-efficacy in general, and that the scores would be influenced by socioeconomic factors. Normal weight ( n  = 40, body mass index Competence Scale (PCS) for healthy eating and exercise, and the General Self-Efficacy Scale (GSES). Composite scores for the three scales were compared between the two groups using the using the two-sample t-test (for normal data) or the Mann-Whitney U test (for non-parametric data). Relationships between the composite scores and patient characteristics were determined using Pearson or Spearman's correlations. The average age of the total cohort was 15.9 ± 1.9 years. 54% were female, and 82% identified as Latino/Hispanic. In comparison to normal weight subjects, overweight/obese adolescents exhibited higher scores for controlled motivation (mean ± standard deviation 28.3 ± 9.3 vs 18.1 ± 8.1) and higher perceived competence [median and 25-75% interquartile range 22.5 (19.0-26.0) vs 20.0 (15.5-25.0)] in relation to eating a healthy diet. These differences persisted after adjustment for age, sex, paternal education, and family income. Overweight/obese adolescents did not lack autonomous motivation but demonstrated higher controlled motivation and perceived competence for healthy eating in comparison to normal weight adolescents, independent of socioeconomic factors. In the clinical practice of weight management, providers should carefully assess adolescents for type of

    Full Text Available There are many different evaluation problems that involve several groups (societies, firms or institutions whose members can be classified into ordered categories, pursuant to their characteristics or their achievements. This paper addresses these types of problems and provides an evaluation criterion based on the distribution of the agents across categories. The starting point is that of dominance relations in pair-wise comparisons. We say that group i dominates group j when the expected category of a member of i is higher than the expected category of a member of j. We introduce the notion of relative advantage of a group to extend this principle to multi-group comparisons and show that there is a unique evaluation function that ranks all groups consistently in terms of this criterion. This function associates to each evaluation problem the (unique dominant eigenvector of a matrix whose entries describe the dominance relations between groups in pair-wise comparisons. The working of the model is illustrated by means of three different applications.

    The purpose of the current study was to assess the uniqueness of the condition of kidney transplant recipients in comparison to a sample of matching healthy peers in relation to body-image dissatisfaction and identification, quality of life and psychological distress. Participants were 45 kidney transplant recipients who were under follow-up care at a Transplant Unit of a major Medical Center, and a sample of 45 matching healthy peers. Measures were taken using self-report questionnaires [Body-Image Ideals Questionnaire (BIIQ), Body Identification Questionnaire (BIQ), Brief Symptoms Inventory (BSI), and the SF-12]. The major findings were the following: (i) kidney transplant recipients reported lower levels of quality of life and higher levels of PsD when compared to their healthy peers; (ii) no difference in body-image dissatisfaction was found between the two studied groups; (iii) significant correlations between body-image dissatisfaction quality of life and PsD were found only in the kidney transplant recipients. The kidney transplantation condition has a moderating effect in the association between body-image dissatisfaction PsD but not in the association between body-image dissatisfaction and quality of life; (iv) kidney transplant recipients experienced higher levels of body identification than did their healthy peers. Taken together, these findings highlight the unique condition of kidney transplant recipients, as well as the function that body-image plays within the self.

    Full Text Available BACKGROUND: Almost 1 in 8 women will have breast cancer during their lifetime. Several risk factors were identified; however, 70% of females with breast cancer have no risk factors. Many risk factors are associated with sex steroid hormones. Some studies have been focused on identification of the indices of cumulative exposures to estrogen during the patients’ life. One of these indicators is bone mineral density (BMD. Our aim was the comparison of BMD in young patients with and without breast cancer, and finding a relationship between breast cancer and bone density. METHODS: In this case-control study, 120 people were enrolled; 40 patients with breast cancer and 80 normal healthy persons as control group. Measurement of BMD was performed in both groups and compared. RESULTS: Both groups were matched in age, weight, age at menarche, age at first marriage and first pregnancy, number of pregnancies over 32 weeks and lactation period, and taking supplemental calcium and vitamin D. However, there was a significant difference between the two groups in terms of estrogen intake, family history of breast cancer, and history of breast masses (P = 0.03, P = 0.03, P ≤ 0.01, respectively. A significant difference was found between BMD, bone mineral content (BMC, and t-scores of lumbar spine of the two groups; they were higher in the control group (P = 0.08, P ≤ 0.01, P = 0.06, respectively. CONCLUSIONS: This study shows that bone mineral density of young patients with breast cancer is not higher than normal similar age females; thus, BMD is not directly a risk factor for breast cancer.

    Objectives: Saliva contains alkaline phosphatase (ALP)—a key intracellular enzyme related to destructive processes and cellular damage—and has buffering capacity (BC) against acids due to the presence of bicarbonate and phosphate ions. Smoking may have deleterious effects on the oral environment due to pH changes which can affect ALP activity. This study aimed to evaluate the salivary pH, BC and ALP activity of male smokers and healthy non-smokers. Methods: This retrospective cohort study took place between August 2012 and December 2013. A total of 251 healthy male non-smokers and 259 male smokers from Hamadan, Iran, were selected. Unstimulated whole saliva was collected from each participant and pH and BC were determined using a pH meter. Salivary enzymes were measured by spectrophotometric assay. Results: Mean salivary pH (7.42 ± 0.48 and 7.52 ± 0.43, respectively; P = 0.018) and BC (3.41 ± 0.54 and 4.17 ± 0.71; P = 0.001) was significantly lower in smokers compared to non-smokers. Mean ALP levels were 49.58 ± 23.33 IU/L among smokers and 55.11 ± 27.85 IU/L among non-smokers (P = 0.015). Conclusion: Significantly lower pH, BC and ALP levels were observed among smokers in comparison to a healthy control group. These salivary alterations could potentially be utilised as biochemical markers for the evaluation of oral tissue function and side-effects among smokers. Further longitudinal studies are recommended to evaluate the effects of smoking on salivary components. PMID:27606111

    Training of working memory as a method of increasing working memory capacity and fluid intelligence has received much attention in recent years. This burgeoning field remains highly controversial with empirically-backed disagreements at all levels of evidence, including individual studies, systematic reviews, and even meta-analyses. The current study investigated the effect of a randomized six week online working memory intervention on untrained cognitive abilities in a community-recruited sample of healthy young adults, in relation to both a processing speed training active control condition, as well as a no-contact control condition. Results of traditional null hypothesis significance testing, as well as Bayesian factor analyses, revealed support for the null hypothesis across all cognitive tests administered before and after training. Importantly, all three groups were similar at pre-training for a variety of individual variables purported to moderate transfer of training to fluid intelligence, including personality traits, motivation to train, and expectations of cognitive improvement from training. Because these results are consistent with experimental trials of equal or greater methodological rigor, we suggest that future research re-focus on: 1) other promising interventions known to increase memory performance in healthy young adults, and; 2) examining sub-populations or alternative populations in which working memory training may be efficacious.

    Schizophrenia patients experience substantial impairments in social cognition (SC) and these deficits are associated with their poor functional outcome. Though SC is consistently shown to emerge as a cognitive dimension distinct from neurocognition, the dimensionality of SC is poorly understood. Moreover, comparing the components of SC between schizophrenia patients and healthy comparison subjects would provide specific insights on the construct validity of SC. We conducted principal component analyses of eight SC test scores (representing four domains of SC, namely, theory of mind, emotion processing, social perception and attributional bias) independently in 170 remitted schizophrenia patients and 111 matched healthy comparison subjects. We also conducted regression analyses to evaluate the relative contribution of individual SC components to other symptom dimensions, which are important clinical determinants of functional outcome (i.e., neurocognition, negative symptoms, motivational deficits and insight) in schizophrenia. A three-factor solution representing socio-emotional processing, social-inferential ability and external attribution components emerged in the patient group that accounted for 64.43% of the variance. In contrast, a two-factor solution representing socio-emotional processing and social-inferential ability was derived in the healthy comparison group that explained 56.5% of the variance. In the patient group, the social-inferential component predicted negative symptoms and motivational deficits. Our results suggest the presence of a multidimensional SC construct. The dimensionality of SC observed across the two groups, though not identical, displayed important parallels. Individual components also demonstrated distinct patterns of association with other symptom dimensions, thus supporting their external validity. Copyright © 2014 Elsevier B.V. All rights reserved.

    Postmortem studies in schizophrenia reveal alterations in gene products that regulate the release and extracellular persistence of GABA. However, results of in vivo studies of schizophrenia measuring total tissue GABA with magnetic resonance spectroscopy (MRS) have been inconsistent. Neither the postmortem nor the MRS studies directly address the physiological properties of GABA neurotransmission. The present study addresses this question through an innovative positron emission tomography (PET) paradigm. The binding of [(11)C]flumazenil, a benzodiazepine-specific PET radiotracer, was measured before and after administration of tiagabine (0.2 mg/kg of body weight), a GABA membrane transporter (GAT1) blocker, in 17 off-medication patients with schizophrenia and 22 healthy comparison subjects. Increased extracellular GABA, through GAT1 blockade, enhances the affinity of GABAA receptors for benzodiazepine ligands, detected as an increase in [(11)C]flumazenil tissue distribution volume (VT). [(11)C]Flumazenil VT was significantly increased across all cortical brain regions in the healthy comparison group but not in the schizophrenia group. This lack of effect was most prominent in the antipsychotic-naive schizophrenia group. In this subgroup, [(11)C]flumazenil ΔVT in the medial temporal lobe was correlated with positive symptoms, and baseline [(11)C]flumazenil VT in the medial temporal lobe was negatively correlated with visual learning. In the healthy comparison group but not the schizophrenia group, [(11)C]flumazenil ΔVT was positively associated with gamma-band oscillation power. This study demonstrates, for the first time, an in vivo impairment in GABA transmission in schizophrenia, most prominent in antipsychotic-naive individuals. The impairment in GABA transmission appears to be linked to clinical symptoms, disturbances in cortical oscillations, and cognition.

    Human T Lymphocyte Virus Type one (HTLV-I) is a retrovirus that infects about 10-20 million people worldwide. Khorasan province in Iran is an endemic area. The majority of HTLV-I-infected individuals sustain healthy carriers but small proportion of infected population developed two progressive diseases: HAM/TSP and ATL. The proviral load could be a virological marker for disease monitoring, therefore in the present study HTLV-I proviral load has been evaluated in ATL and compared to HAM/TSP and healthy carriers. In this case series study, 47 HTLV-I infected individuals including 13 ATL, 23 HAM/TSP and 11 asymptomatic subjects were studied. Peripheral blood mononuclear cells (PBMCs) were investigated for presence of HTLV-I DNA provirus by PCR using LTR and Tax fragments. Then in infected subjects, HTLV-I proviral load was measured using real time PCR TaqMan method. The average age of patients in ATL was 52±8, in HAM/TSP 45.52±15.17 and in carrier's 38.65±14.9 years which differences were not statistically significant. The analysis of data showed a significant difference in mean WBC among study groups (ATL vs HAM/TSP and carriers P=0.0001). Moreover, mean HTLV-I proviral load was 11967.2 ± 5078, 409 ± 71.3 and 373.6 ± 143.3 in ATL, HAM/TSP and Healthy Carriers, respectively. The highest HTLV-I proviral load was measured in ATL group that had a significant correlation with WBC count (R=0.495, P=0.001). The proviral load variations between study groups was strongly significant (ATL vs carrier P=0.0001; ATL vs HAM/TSP P= 0.0001 and HAM/TSP vs carriers P< 0.05). Conclusion : The present study demonstrated that HTLV-I proviral load was higher in ATL group in comparison with HAM/TSP and healthy carriers. Therefore, HTLV-I proviral load is a prognostic factor for development of HTLV-I associated diseases and can be used as a monitoring marker for the efficiency of therapeutic regime.

    [Purpose] This study aimed to compare dynamic balance ability according to foot shape, defined as normal, pronated, or supinated on the basis of the height of the medial arch. [Subjects] In this study, 14 subjects for the pronated foot group, 14 for the supinated foot group, and 14 for the normal foot group were selected from among 162 healthy university students by using the navicular drop test proposed by Brody. To measure dynamic balance ability, a star excursion balance test (SEBT) was conducted for each group, in which a cross-shaped line and lines at 45° in eight directions were drawn on the floor. In this study, only three directions were used, namely anterior, posterolateral, and posteromedial. The mean of the SEBT was calculated by measuring three times for each group, and the values were standardized using the following equation: measured value/leg length × 100. [Results] No significant differences in dynamic balance ability were found between the normal, pronated, and supinated foot groups. [Conclusion] No significant differences in dynamic balance ability according to the foot shape were found among the healthy university students with normal, pronated, and supinated feet.

    To investigate how a pilot environmental intervention changed food sales patterns in carryout restaurants. Quasi-experimental. Low-income neighborhoods of Baltimore, Maryland. Seven carryouts (three intervention, four comparison). Phase 1, menu board revision and healthy menu labeling; phase 2, increase of healthy sides and beverages; and phase 3, promotion of cheaper and healthier combination meals. Weekly handwritten menu orders collected to assess changes in the proportion of units sold and revenue of healthy items (entrée, sides and beverages, and combined). Logistic and Poisson regression models with generalized estimating equations. In the intervention group, odds for healthy entrée units and odds for healthy side and beverage units sold significantly increased in phases 2 and 3; odds for healthy entrée revenue significantly increased in phase 1 (odds ratio [OR] 1.16, 95% confidence interval [CI] 1.08-1.26), phase 2 (OR 1.32, 95% CI 1.25-1.41), and phase 3 (OR 1.39, 95% CI 1.14-1.70); and odds for healthy side and beverage revenues increased significantly in phase 2 (OR 1.62, 95% CI 1.33-1.97) and phase 3 (OR 2.73, 95% CI 2.15-3.47) compared to baseline. Total revenue in the intervention group was significantly higher in all phases than in the comparison group (p selection, and competitive pricing can increase availability and sales of healthy items in carryouts.

    This study examined the multidimensional self-concept, global self-esteem and psychological adjustment of individuals with traumatic brain injury (TBI) as compared with healthy controls. Group comparison on self-report questionnaires. Forty-one individuals who had sustained a TBI were compared with an age- and gender-matched sample of 41 trauma-free control participants on the Rosenberg Self Esteem Scale, the Tennessee Self Concept Scale (second edition) and the Hospital Anxiety and Depression Scales (HADS). Participants with TBI rated significantly lower mean levels of global self-esteem and self-concept on the Rosenberg Self Esteem Scale and Tennessee Self Concept Scale than the control group. Survivors of TBI rated themselves more poorly on a range of self-dimensions, including social, family, academic/work and personal self-concept compared to controls. They also reported higher mean levels of depression and anxiety on the Hospital Anxiety and Depression Scale. Overall self-concept was most strongly associated with depressive symptoms and anxiety. Self-concept may be lowered following TBI and is associated with negative emotional consequences. Clinicians may improve the emotional adjustment of survivors of TBI by considering particular dimensions of self-concept for intervention focus.

    The faecal flora is a common reservoir for urinary tract infection (UTI), and Escherichia coli (E. coli) is frequently found in this reservoir without causing extraintestinal infection. We investigated these E. coli reservoirs by whole-genome sequencing a large collection of E. coli from healthy...... controls (faecal), who had never previously had UTI, and from UTI patients (faecal and urinary) sampled from the same geographical area. We compared MLST types, phylogenetic relationship, accessory genome content and FimH type between patient and control faecal isolates as well as between UTI and faecal......-only isolates, respectively. Comparison of the accessory genome of UTI isolates to faecal isolates revealed 35 gene families which were significantly more prevalent in the UTI isolates compared to the faecal isolates, although none of these were unique to one of the two groups. Of these 35, 22 belonged...

    Understanding views about what constitutes a healthy diet in diverse populations may inform design of culturally tailored behavior change interventions. The objective of this study was to describe perspectives on healthy eating among Chinese and American young adults and identify similarities and differences between these groups. Chinese (n = 55) and American (n = 57) undergraduate students in Changsha, Hunan, China and Honolulu, Hawai'i, U.S.A. composed one- to two-paragraph responses to the following prompt: "What does the phrase 'a healthy diet' mean to you?" Researchers used content analysis to identify predominant themes using Dedoose (version 5.2.0, SocioCultural Research Consultants, LLC, Los Angeles, CA, 2015). Three researchers independently coded essays and grouped codes with similar content. The team then identified themes and sorted them in discussion. Two researchers then deductively coded the entire data set using eight codes developed from the initial coding and calculated total code counts for each group of participants. Chinese students mentioned physical outcomes, such as maintaining immunity and digestive health. Timing of eating, with regular meals and greater intake during day than night, was emphasized. American students described balancing among food groups and balancing consumption with exercise, with physical activity considered essential. Students also stated that food components such as sugar, salt and fat should be avoided in large quantities. Similarities included principles such as moderation and fruits and vegetables as nutritious, and differences included foods to be restricted and meal timing. While both groups emphasized specific foods and guiding dietary principles, several distinctions in viewpoints emerged. The diverse views may reflect food-related messages to which participants are exposed both through the media and educational systems in their respective countries. Future studies may further examine themes that may

    Virtual focus groups-such as online chat and video groups-are increasingly promoted as qualitative research tools. Theoretically, virtual groups offer several advantages, including lower cost, faster recruitment, greater geographic diversity, enrollment of hard-to-reach populations, and reduced participant burden. However, no study has compared virtual and in-person focus groups on these metrics. To rigorously compare virtual and in-person focus groups on cost, recruitment, and participant logistics. We examined 3 focus group modes and instituted experimental controls to ensure a fair comparison. We conducted 6 1-hour focus groups in August 2014 using in-person (n=2), live chat (n=2), and video (n=2) modes with individuals who had type 2 diabetes (n=48 enrolled, n=39 completed). In planning groups, we solicited bids from 6 virtual platform vendors and 4 recruitment firms. We then selected 1 platform or facility per mode and a single recruitment firm across all modes. To minimize bias, the recruitment firm employed different recruiters by mode who were blinded to recruitment efforts for other modes. We tracked enrollment during a 2-week period. A single moderator conducted all groups using the same guide, which addressed the use of technology to communicate with health care providers. We conducted the groups at the same times of day on Monday to Wednesday during a single week. At the end of each group, participants completed a short survey. Virtual focus groups offered minimal cost savings compared with in-person groups (US $2000 per chat group vs US $2576 per in-person group vs US $2,750 per video group). Although virtual groups did not incur travel costs, they often had higher management fees and miscellaneous expenses (eg, participant webcams). Recruitment timing did not differ by mode, but show rates were higher for in-person groups (94% [15/16] in-person vs 81% [13/16] video vs 69% [11/16] chat). Virtual group participants were more geographically diverse (but

    The objective of this study is to compare the gait variability of patients with lumbar spinal stenosis (experimental group) with healthy individuals (control group). The hypothesis is that the preoperative gait variability of the experimental group is higher than the control group. The experimental group consisted of 35 adults (18 males, 17 females). The subjects of the experimental group suffered exclusively from spinal stenosis. The patients were determined by MRI scans. A tri-axial accelerometer sensor was used for the gait measurement, and differential entropy algorithm was used to quantify the gait acceleration signal. The Oswestry Low Back Pain Questionnaire was used to determine the condition on the day of the measurement. Receiver operating characteristic (ROC) was utilized to assess the diagnostic value of the method and determine a cut-off value. There is a statistically significant difference between gait variability in the control group and the experimental group. ROC analysis determines a cut-off differential entropy value. The cut-off value has a 97.6% probability of separating patients with spinal stenosis from healthy subjects. The Oswestry Low Back Questionnaire is well correlated with the spectral differential entropy values

    To evaluate catalase (CAT, EC 1.11.1.6) activity in healthy and inflamed dental pulp of young patient's teeth and to investigate if an active defense system oxidizing agents is present as a response to bacterial invasion. Twenty young patients between 15 and 25 ages, who were diagnosed to be healthy, were the source of the pulp tissue. The situation of the dental pulps was evaluated using clinical and radiographic assessments. The patients were divided two groups from healthy, and inflamed pulp tissues were obtained; each participant provided one pulp tissue specimens. The specimens were collected during endodontic treatment or by longitudinally grooving and splitting the teeth (if extracted). Catalase activity was determined through spectrophotometric methods and an independent sample t-test assessed the significance of differences between the groups. There was statistically a difference between healthy pulp tissue and inflamed pulp tissue (P catalase activity of healthy group was significantly lower than inflamed pulp groups. The present study has shown that a significant increase in catalase activity is determined in inflamed dental pulps, which is due to pulpitis in comparison to healthy dental pulp.

    Objectives Comparison groups are essential for accurate testing and interpretation of yoga intervention trials. However, selecting proper comparison groups is difficult because yoga comprises a very heterogeneous set of practices and its mechanisms of effect have not been conclusively established. Methods We conducted a systematic review of the control and comparison groups used in published randomized controlled trials (RCTs) of yoga. Results We located 128 RCTs that met our inclusion criteria; of these, 65 included only a passive control and 63 included at least one active comparison group. Primary comparison groups were physical exercise (43%), relaxation/meditation (20%), and education (16%). Studies rarely provided a strong rationale for choice of comparison. Considering year of publication, the use of active controls in yoga research appears to be slowly increasing over time. Conclusions Given that yoga has been established as a potentially powerful intervention, future research should use active control groups. Further, care is needed to select comparison conditions that help to isolate the specific mechanisms of yoga’s effects. PMID:25440384

    Empirical interest in mental imagery in social anxiety disorder (SAD) has grown over the past years but still little is known about the specificity to SAD. The present study therefore examines negative autobiographical memories in participants with social anxiety disorder (SAD), compared to patients with panic disorder (PD), and healthy controls (HCs). A total of 107 participants retrieved four memories cued by verbal phrases associated with either social anxiety (SA) or panic anxiety (PA), with two memories for each cue category. PA-cued memories were experienced with stronger imagery and as more traumatic. They were also rated as more central to identity than SA-cued memories, but not among participants with SAD, who perceived SA-cued memories as equally central to their identity. When between-group effects were detected, participants with anxiety disorders differed from HCs, but not from each other. Central limitations include reliance on self-report measures, comorbidity in the anxiety disorder groups, and lack of a neutrally cued memory comparison. The findings align with models of SAD suggesting that past negative social events play a central role in this disorder. Future research is suggested to further explore the function of negative memories, not only in SAD, but also in other anxiety disorders. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Chronic hemoglobinopathies like thalassemia are associated with many osteopathies like osteoporosis. Methods. This observational study was carried out to compare the bone mineral density (BMD in transfusion dependent thalassemics with that of healthy controls. Thirty-two thalassemia patients, aged 2–18 years, and 32 age and sex matched controls were studied. The bone mineral concentration (BMC and BMD were assessed at lumbar spine, distal radius, and neck of femur. Biochemical parameters like serum calcium and vitamin D levels were also assessed. Results. The BMC of neck of femur was significantly low in cases in comparison to controls. We also observed significantly lower BMD at the lumbar spine in cases in comparison to controls. A significantly positive correlation was observed between serum calcium levels and BMD at neck of femur. Conclusion. Hence, low serum calcium may be used as a predictor of low BMD especially in populations where incidence of hypovitaminosis D is very high.

    This study explored adult's attitudes and reactions to a range of television advertisements (ads) promoting healthy weight, physical activity and healthy eating. Twenty-four focus groups (N = 179) were conducted in metropolitan and regional areas of the Australian states of Victoria, New South Wales (NSW) and Queensland, with participants segmented by sex, education (no tertiary, at least some tertiary) and life stage (young adults, parents). Each group was assigned to one of the three advertising streams - Weight, Activity, or Nutrition - where responses to five different ads were explored using semi-structured, moderator-led discussions. Discussion transcripts were qualitatively content analysed using a conventional approach. Four main themes were identified in participants' discussions about the ads' main messages - (i) Why is it a problem? (ii) Who is it a problem for? (iii) What should I do about it? (iv) How do I make the changes? Reactions varied by demographic factors and current weight and lifestyle status. Participants furthest from achieving public health recommendations for weight, diet and activity were motivated by 'what' and 'how' ads involving gentle persuasion and helpful hints. Participants who were closer to meeting these recommendations were motivated by 'why' ads featuring more graphic and emotive content and new information. Findings suggest a strategic approach is important for the development of public health ads promoting healthy weight and lifestyle, with consideration given to the specific communication goals and who the target audience is. This should help ensure an appropriate message is delivered to priority population subgroups in the most informative and motivating manner. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The objective of this study was to assess changes in adolescent girls' health-enhancing cognitions and behaviors targeted by the Go Girls! group-based mentorship lifestyle program. Three hundred and ten adolescent girls (nested within 40 Go Girls! groups) completed questionnaires that assessed cognitions (attitudes, self-regulatory efficacy, and intentions) and behaviors (physical activity and dietary) at four time points (two pre-program, one at the end of the program, and one at 7-week follow-up). Hierarchical linear modeling was used to examine changes in the outcome variables among Go Girls! participants (M age = 11.68 years, SD = 0.80). No significant changes occurred in the outcome variables during the baseline comparison period (Time 1-2). When compared to the average of the baseline assessments, 7 weeks after completing the program, girls reported significant improvements in physical activity (M Baseline PAtotal = 3.82, SD = 3.49; M T4 PAtotal = 4.38, SD = 3.75) and healthy eating (M Baseline = 10.71, SD = 1.13; M T4 = 11.35, SD = 1.05) behavior and related cognitions (d values ≥0.65). Findings provide preliminary support for programs that foster belongingness and target health behaviors through mentorship models.

    Full Text Available Background: Protein-energy malnutrition (PEM is a common complication in pediatric patients with chronic kidney disease (CKD. Components incorporated in the regulation of appetite and body composition appear to be of the focus in renal insufficiency and may influence the CKD-associated PEM. The purpose of this study was to investigate plasma levels of appetite-regulating hormones and their correlation with the body composition variables in a pediatric in predialysis stage of CKD. Methods: Thirty children with CKD in predialysis stage were selected and compared with 30 healthy sex- and age-matched controls. Blood samples were collected in fasting. Serum total ghrelin, leptin, and obestatin levels were measured using enzyme immunometric assay methods. Anthropometric parameters measurement and body composition analysis were done using the bioelectric impedance analysis (BIA method. Results: Patients showed insignificant elevated total ghrelin (105.40±30.83 ng/l, leptin (5.32±1.17 ng/ml and obestatin (5.07±1.09 ng/ml levels in comparison with healthy participants. By using BIA, patients had significantly different Dry Lean Weight (P=0.048, Extra Cellular Water (P=0.045, Body Cell Mass (BCM (P=0.021, Basal Metabolic Rate (P=0.033 and Body Mass Index (P=0.029 compared with controls. Furthermore, the total body water was slightly and the ECW was significantly higher in CKD participants. There were significant negative correlation between obestatin and BCM (r=-0.40, P=0.03 and fat free mass index (FFMI (r=-0.40, P=0.029 in patients. Conclusion: It seems that our results are insufficient to clarify the role of appetite-regulating hormones in PEM in CKD patients. It is apparent that there are still many unknown parameters related to both appetite regulating and CKD-associated PEM.

    Background Reference intervals for venous blood parameters differs with age, gender, geographic region, and ethnic groups. Hence local laboratory reference intervals are important to improve the diagnostic accuracy of health assessments and diseases. However, there have been no comprehensive published reference intervals established in Oman, the Gulf Cooperation Council or Middle Eastern countries. Hence, the aim of this study was to establish reference intervals for full blood count in healthy Omani adults. Methods Venous blood specimens were collected from 2202 healthy individuals aged 18 to 69 years from January 2012 to April 2017, and analysed by Sysmex XS-1000i and Cell-Dyn Sapphire automated haematology analysers. Results were statistically analysed and compared by gender, age, and ABO blood group. The lower and upper reference limits of the haematology reference intervals were established at the 2.5th and 97.5th percentiles respectively. Results Reference intervals were calculated for 17 haematology parameters which included red blood cell, white blood cell, and platelet parameters. Red blood cell (RBC), haemoglobin (HGB), haematocrit (HCT), platelet and platelet haematocrit counts of the healthy donors were significantly different between males and females at all ages (p values of RBC, HGB and HCT than females. Other complete blood count parameters showed no significant differences between genders, age groups, instruments, or blood groups. Our study showed a lower haemoglobin limit for the normal reference interval in males and females than the currently used in Oman. Conclusions Data from this study established specific reference intervals which could be considered for general use in Oman. The differences in haematology reference intervals highlights the necessity to establish reference intervals for venous blood parameters among the healthy population in each country or at least in each region.

    This study explores the influence of different social reference points and different comparison group sizes on risky decision-making. Participants were presented with a scenario describing an exam, and presented with the opportunity of making a risky decision in the context of different information provided about the performance of their peers. We found that behavior was influenced, not only by comparison with peers, but also by the size of the comparison group. Specifically, the larger the reference group, the more polarized the behavior it prompted. In situations describing social loss, participants were led to make riskier decisions after comparing themselves against larger groups, while in situations describing social gain, they become more risk averse. These results indicate that decision making is influenced both by social comparison and the number of people making up the social reference group.

    Full Text Available Abstract Background Understanding views about what constitutes a healthy diet in diverse populations may inform design of culturally tailored behavior change interventions. The objective of this study was to describe perspectives on healthy eating among Chinese and American young adults and identify similarities and differences between these groups. Methods Chinese (n = 55 and American (n = 57 undergraduate students in Changsha, Hunan, China and Honolulu, Hawai’i, U.S.A. composed one- to two-paragraph responses to the following prompt: “What does the phrase ‘a healthy diet’ mean to you?” Researchers used content analysis to identify predominant themes using Dedoose (version 5.2.0, SocioCultural Research Consultants, LLC, Los Angeles, CA, 2015. Three researchers independently coded essays and grouped codes with similar content. The team then identified themes and sorted them in discussion. Two researchers then deductively coded the entire data set using eight codes developed from the initial coding and calculated total code counts for each group of participants. Results Chinese students mentioned physical outcomes, such as maintaining immunity and digestive health. Timing of eating, with regular meals and greater intake during day than night, was emphasized. American students described balancing among food groups and balancing consumption with exercise, with physical activity considered essential. Students also stated that food components such as sugar, salt and fat should be avoided in large quantities. Similarities included principles such as moderation and fruits and vegetables as nutritious, and differences included foods to be restricted and meal timing. While both groups emphasized specific foods and guiding dietary principles, several distinctions in viewpoints emerged. Conclusions The diverse views may reflect food-related messages to which participants are exposed both through the media and educational systems in their

    Full Text Available Introduction: Behcet’s Disease (BD is a general and progressive vasculitis and involves various organs. Its main etiology is not yet understood; however, immunologic and infectious causes and genetic predisposition have been proposed. Saccharomyces Cerevisiae is a type of yeast which is used in the bread and wine industries. Antibodies against this yeast have a well-proven role in inflammatory bowel diseases. The aim of the present study was to assess the frequency of Anti-Saccharomyces Cerevisiae Antibody (ASCA and its relation to clinical symptoms and disease activity index in patients afflicted by BD. Materials and Methods: Serum ASCA levels, determined by ELISA, were Studied in Behcet’s disease along with oral aphthosis, other rheumatologic diseases and healthy volunteers (n=30 in each group. In the BD group the disease activity index and different clinical symptoms were recorded during the study course. Results:Serum level of ASCA in the four studied groups of BD, oral aphthosis, other rheumatologic disease and healthy volunteers was 9.18±9.69, 10.90±10.40, 11.29±17.96 and 8.86±5.31IU/ml, respectively;  indicating no meaningful difference (p=0.811. The ASCA titer was not related to Behcet’s disease severity (p=0.399. Serum level of ASCA in BD patients with oral aphthosis or with gastrointestinal symptoms was significantly higher than the other Behcet’s Disease patients (p=0.012, p=0.014. Conclusion: ASCS is not a valuable test for distinguishing BD from recurrent oral aphthosis or other connective tissue disorders. It also cannot be used for determining disease severity. However, it has a higher level in BD patients with oral aphthous ulcers and gastrointestinal symptoms.

    Measure of liver enzymes may help to increase safety of blood donation for both blood donor and recipient. Determination of liver enzymes may prepare valuable clinical information. To assess serum γ-Glutamyltransferase (GGT), Alanine Aminotransferase (ALT), and Aspartate Aminotransferase (AST) activities in healthy blood donors in different ethnic groups in Gorgan. This study was performed in 450 healthy male blood donors, in three ethnic groups (Fars, Sistanee and Turkman) who attended Gorgan blood transfusion center. Liver enzymes (GGT, ALT and AST) were determined. Serum AST and ALT in three ethnic groups were significant except for serum GGT levels. There was significant correlation between family histories of liver disease and systolic blood pressure and AST in Fars, and GGT in Sistanee ethnic groups. Several factors, such as age, family history of diabetes mellitus, family history of liver disease and smoking habit had no effect on some liver enzymes in different ethnic groups in this area. Variation of AST, ALT, and GGT enzyme activities in healthy subjects was associated with some subjects in our study groups. According to our study, it suggests that screening of AST and GGT enzymes in subjects with family history of liver disease is necessary in different ethnic groups.

    Full Text Available OBJECTIVE: Epilepsy is characterized by sudden seizures and loss of control in patients; it leads to constantly be under stress. Psychiatric disorders, particularly depressive disorders are more frequent in patients with epilepsy than in the whole of society. In this study; we aimed to compare depression,anxiety and desperation levels between epileptic patients and healthy ones. METHODS: 34 patients and 34 healthy controls were enrolled to the study. Demographic features of all subjects were also recorded. Neurologic examination, Electroencephalography (EEG and cranial magnetic resonance imaging(MRI of patients were also evaluated. State-Trait Anxety Inventory (STAI is for anxiety, Beck Depression Inventory (BDE is for depression, Beck Hopelessness Scale (BUO is for hopelessness were evaluated. RESULTS: Epileptic patients were with mean age of 24.56 ± 8.49, healthy subjects were with the mean age 27.44 ± 5.66 years. 13 of patients were female(38.2% and 21 patients were male(%38.2 in all groups.There was no significant difference about demographic features(p>0.05. When continuous and instant anxiety levels of epileptic and healthy groups were compared, no significant difference was observed between instant anxiety levels(p> 0.05; but there was difference between continuous anxiety levels (p <0.05. Also, hopelessness and depression levels were similar between groups (p<0.05. CONCLUSION: The results of the study showed that depression, anxiety and hopelessness levels were higher in epileptic patients when compared to healthy people. In addition, patients with seizure control with less drug use will reduce the level of trait anxiety was concluded.

    Studies are lacking that analyze how clinically referred adolescents and healthy adolescents cope with everyday stressors. Clinically referred adolescents from three problematic domains (diverse disorders including delinquency, drug abuse, and depression) were compared to healthy adolescents using the Coping Across Situations Questionnaire (Seiffge-Krenke, 1995) and a short version of the Youth Self-Report (Achenbach, 1991). The different clinical groups (n = 469) showed unique patterns concerning their coping styles. The group of depressed youth altogether showed lower coping activities. The youth from institutions for drug abusive youth used more dysfunctional coping. The adolescents from youth welfare services (diverse disorders including delinquency) were more active in both dysfunctional and functional coping than the other two clinically referred groups. The control group showed more functional and less dysfunctional coping. The clinically referred adolescents did not differentiate in their coping behavior, depending on the type of stressor. Gender effects were apparent, albeit negligible. Clinically referred youth are unable to adapt their coping behavior according to the given situation.

    Full Text Available ABSTRACT Purpose: To investigate subfoveal choroidal thickness (SFCT in patients with pre-eclampsia using enhanced depth imaging optical coherence tomography (EDI-OCT. Methods: A sample of 73 pregnant women was studied over 28 weeks of gestation. The sample was divided into two groups: one comprising pre-eclamptic pregnant women (n=32, and the other comprising healthy pregnant women (n=41. The SFCT was determined for all patients using EDI-OCT during pregnancy and at the third month of the postpartum period. Results: The SFCTs in pre-eclamptic pregnant women were 351.97 ± 22.44 and 332.28 ± 20.32 µm during the pregnancy and postpartum periods (p<0.001, respectively, whereas these values in healthy pregnant women were 389.73 ± 49.64 and 329.78 ± 22.36 µm (p<0.001, respectively. During pregnancy SFCT in pre-eclamptic pregnant women was significantly thinner than that in healthy pregnant women (p<0.001. However, there was no statistically significant difference during the postpartum period (p=0.623. Conclusions: The results suggest that SFCT is significantly decreased in pre-eclamptic pregnant women than in healthy pregnant women, despite no statistically significant difference in SFCT existing between the groups during the postpartum period.

    The main aim of the study was to analyze and compare attention and memory performance in pediatric patients with cystic fibrosis (CF), inflammatory bowel disease (IBD) and in healthy controls. 28 patients with CF, 30 patients with IBD and 30 healthy subjects took part in the study (all in age range of 7-17). All subjects were in intellectual norm. To analyze the functioning of attention, the d2 Test of Attention by Brickenkamp (d2 test) was applied. Memory performance was assessed using the Benton Visual Retention Test (BVRT) and the Trial of 10 words. The CF and IBD groups committed significantly more errors in the d2 test than the healthy controls. The CF group also had significantly higher fluctuation rates and received significantly lower scores in overall concentration performance than the control group. Patients with CF made more mistakes and had fewer correct memory projections in BVRT than the healthy controls. Patients with IBD committed significantly more errors in BVRT than the control group. Patients with CF and IBD also got significantly lower scores in the Trial of 10 words than the control group. Pediatric patients with CF and IBD performed more poorly than the healthy controls on attention and memory tests. More distinct cognitive impairments were observed in the CF group. Further research is needed to find the underlying mechanisms and clinical and/or functional significance of observed cognitive deficits. © American Federation for Medical Research (unless otherwise stated in the text of the article) 2017.

    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 relevance of the gut microbiota to human health is increasingly appreciated. The objective of this study was to compare the gut microbiota of a group of adult tribals with that of healthy adult villagers in Tamil Nadu, India. Faeces were collected from 10 healthy tribal adults (TAs) in the Jawadhi hills and from 10 healthy villagers [rural adults (RAs)] in Vellore district, Tamil Nadu. DNA was extracted, and 456 bp segments comprising hypervariable regions 3 and 4 of the 16S rRNA gene were amplified, barcoded and 454 sequenced. Totally 227,710 good-quality reads were analyzed. TAs consumed a millets-based diet, ate pork every day, and did not consume milk or milk products. RAs consumed a rice-based diet with meat intake once a week. In both groups, Firmicutes was the most abundant phylum, followed by Proteobacteria, Bacteroidetes and Actinobacteria. The median Firmicutes-to-Bacteroidetes ratio was 34.0 in TA and 92.9 in RA groups. Actinobacteria were significantly low in TA, possibly due to non-consumption of milk. Clostridium constituted the most abundant genus in both groups, but was significantly more abundant in TAs than RAs, while Streptococcus was significantly more abundant in RA (P<0.05). Analyses of genetic distance revealed that the microbiota were distinctly different between TA and RA, and principal component analysis using 550 distinct taxonomically identifiable sequences revealed a clear separation of microbiota composition in the two groups. Phylogenetic analysis of major microbiota indicated clustering of microbial groups at different major branch points for TAs and RAs. Phylum Firmicutes and genus Clostridium constituted the bulk of the faecal microbiota, while significant differences in composition between the groups were probably due to differences in diet and lifestyle.

    Borderline Personality Disorder (BPD) is a highly prevalent diagnosis in mental health care and includes a heterogeneous constellation of symptoms. As the field of personality disorder (PD) research moves to emphasize dimensional traits in its operationalization, it is important to determine how the alternative DSM-5 Section III personality trait dimensions differentiates such features in BPD patients versus comparison groups. To date, no study has attempted such validation. The current study examined the utility of the DSM-5 trait dimensions in differentiating patients with the categorical DSM-IV/5 diagnosis of BPD (n=101) from systematically matched samples of other PD patients (n=101) and healthy controls (n=101). This was investigated using one-way ANOVA and multinomial logistic regression analyses. Results indicated that Emotional Lability, Risk Taking, and Suspiciousness uniquely differentiated BPD patients from other PD patients, whereas Emotional Lability, Depressivity, and Suspiciousness uniquely differentiated BPD patients from healthy controls. Emotional Lability is in particular a key BPD feature of the proposed Section III model, whereas Suspiciousness also augments essential BPD features. Provided that these findings are replicated cross-culturally in forthcoming research, a more parsimonious traits operationalization of BPD features is warranted. Copyright © 2016 Elsevier Masson SAS.

    Saliva contains alkaline phosphatase (ALP)-a key intracellular enzyme related to destructive processes and cellular damage-and has buffering capacity (BC) against acids due to the presence of bicarbonate and phosphate ions. Smoking may have deleterious effects on the oral environment due to pH changes which can affect ALP activity. This study aimed to evaluate the salivary pH, BC and ALP activity of male smokers and healthy non-smokers. This retrospective cohort study took place between August 2012 and December 2013. A total of 251 healthy male non-smokers and 259 male smokers from Hamadan, Iran, were selected. Unstimulated whole saliva was collected from each participant and pH and BC were determined using a pH meter. Salivary enzymes were measured by spectrophotometric assay. Mean salivary pH (7.42 ± 0.48 and 7.52 ± 0.43, respectively; P = 0.018) and BC (3.41 ± 0.54 and 4.17 ± 0.71; P = 0.001) was significantly lower in smokers compared to non-smokers. Mean ALP levels were 49.58 ± 23.33 IU/L among smokers and 55.11 ± 27.85 IU/L among non-smokers (P = 0.015). Significantly lower pH, BC and ALP levels were observed among smokers in comparison to a healthy control group. These salivary alterations could potentially be utilised as biochemical markers for the evaluation of oral tissue function and side-effects among smokers. Further longitudinal studies are recommended to evaluate the effects of smoking on salivary components.

Z scores of leukocyte telomere length were derived within each case-control study. Based on prior work, we defined low-risk or healthy categories for five major modifiable factors assessed in 1988 or 1990: non-current smoking, maintaining a healthy body weight (body mass index in 18.5-24.9 kg/m(2, engaging in regular moderate or vigorous physical activities (≥150 minutes/week, drinking alcohol in moderation (1 drink/week to <2 drinks/day, and eating a healthy diet (Alternate Healthy Eating Index score in top 50%. We calculated difference (% of the z scores contrasting low-risk groups with reference groups to evaluate the association of interest.Although none of the individual low-risk factors was significantly associated with larger leukocyte telomere length z scores, we observed a significant, positive relationship between the number of low-risk factors and the z scores. In comparison with women who had zero low-risk factors (1.9% of the total population and were, therefore, considered the least healthy group, the leukocyte telomere length z scores were 16.4%, 22.1%, 28.7%, 22.6%, and 31.2% (P for trend = 0.015 higher for women who had 1 to 5 low-risk factors, respectively.Adherence to a healthy lifestyle, defined by major modifiable risk factors, was associated with longer telomere length in leukocytes.

    The aim of this study was the assessment of the quality of life of children and adolescents with tension headaches in comparison with healthy peers. The study was conducted on 135 middle school and high school students in Poznań and on 86 children with tension headaches, that were treated in the out-patient clinic of The Chair and Clinic of Development Age Neurology of Karol Marcinkowski University of Medical Sciences in Poznań. The research tool for both groups was Pediatric Quality of Life Inventory, version 4.0 (PedsQL 4.0) questionnaire. In the analysed groups dominated 14- and 16-year-old children. Among children with tension headaches, the ailments usually appeared once or twice a week in 39 (45%) of them. With the use of the PedsQL 4.0 questionnaire the following fields of activity were analyzed: biological, emotional, social functioning and mood. The biggest discrepancies between the group of healthy children and those with headaches were noted in the field of emotional functioning and mood. Adolescents with tension headaches more frequently reported the feeling of fear and sleep disorders in comparison to healthy students. Children with headaches look at the future in a more pessimistic way and are less satisfied with their lives.

    Pricing strategies are mentioned frequently as a potentially effective tool to stimulate healthy eating, mainly for consumers with a low socio-economic status. Still, it is not known how these consumers perceive pricing strategies, which pricing strategies are favoured and what contextual factors are important in achieving the anticipated effects. We conducted seven focus groups among 59 residents of deprived neighbourhoods in two large Dutch cities. The focus group topics were based on insights from Rogers' Diffusion of Innovations Theory and consisted of four parts: 1) discussion on factors in food selection; 2) attitudes and perceptions towards food prices; 3) thinking up pricing strategies; 4) attitudes and perceptions regarding nine pricing strategies that were nominated by experts in a former Delphi Study. Analyses were conducted with Atlas.ti 5.2 computer software, using the framework approach. Qualitative analyses revealed that this group of consumers consider price to be a core factor in food choice and that they experience financial barriers against buying certain foods. Price was also experienced as a proficient tool to stimulate healthier food choices. Yet, consumers indicated that significant effects could only be achieved by combining price with information and promotion techniques. In general, pricing strategies focusing on encouraging healthy eating were valued to be more helpful than pricing strategies which focused on discouraging unhealthy eating. Suggested high reward strategies were: reducing the price of healthier options of comparable products (e.g., whole meal bread) compared to unhealthier options (e.g., white bread); providing a healthy food discount card for low-income groups; and combining price discounts on healthier foods with other marketing techniques such as displaying cheap and healthy foods at the cash desk. This focus group study provides important new insights regarding the use of pricing strategies to stimulate healthy eating

    Allergic responses in humans, horses and other species are mediated by immunoglobulin E (IgE) antibodies. Serum testing to detect allergen-specific IgE antibodies has been developed for dogs, cats and horses; this allows for the identification of allergens and determination of appropriate allergen- specific immunotherapies. This study compared serum allergen-specific IgE concentrations in atopic and healthy horses. The study was performed on Malopolski breed atopic (n=21) and nonatopic (n=21) clinically healthy horses. Allergen-specific IgE serum concentrations were measured in summer seasons of 2008-2015 using a monoclonal anti-IgE antibody. A Northern and Central European allergen panel containing mite, insect, mould and plant pollen allergens, including 15 tests of individual allergens and 5 tests of allergen mixtures was used. The mean allergen-specific IgE concentrations in the atopic and normal horse populations were compared. Among the atopic horses, the strongest positive reactions occurred against the storage mites Tyrophagus putrescentiae and the domestic mite Dermatophagoides farinae. The atopic horses also demonstrated high IgE concentrations against insects, particularly Tabanus sp., the plant pollens colza, cultivated rye and the mould pollen mixture Aspergillus/Penicillium. No horses in the atopic group were IgE-negative. Among all mite, insect, mould and some plant allergen groups the differences in mean specific IgE concentrations between allergic and healthy horses were significant. The mean IgE concentrations for most allergen groups were significantly higher in the atopic horses than in the healthy animals. However, a high incidence of positive reactions was observed in both healthy and allergic horses. Our results showed a high frequency of polysensitization in atopic horses.

    Continued progress over the next decade in reducing premature morbidity and mortality from chronic disease will require that health communication efforts target a significant proportion of the American public that has not been influenced by the health promotion efforts of the 1980s. Focus groups conducted with members of the hard-to-reach American public showed that while being healthy seemed to be important to participants, and they were generally aware of what to do to stay healthy, they had a different operational definition of health than that used in health promotion programs. Participants seemed to believe that better health behaviors would build their resistance to acute illnesses, that is, keep them healthy, but that chronic diseases, such as cancer and diabetes, were due to fate and heredity and beyond their individual control. The focus group results show that participants had not made the link between chronic disease prevention and the importance of diet, exercise, and weight control. Although most of them seemed to express a genuine interest in "doing better," they were not able to supply more than superficial examples of how such changes might be made. Surprisingly, there were more similarities than differences in participants' attitudes and beliefs, with the similarities cutting across boundaries of race-ethnicity, age, and sex. Interest in changing behaviors was only slightly more pronounced among female rather than male, and older rather than younger, participants. However, there was not much evidence from the participants that they were actively seeking health information or trying to reconcile conflicting knowledge and beliefs.

    High serum uric acid (sUA) has been reported to be a risk factor for hypertension however, whether this is the case for all age groups is not clear. We examined the association between sUA concentrations and systolic and diastolic blood pressure (SBP and DBP) in different age groups in a cohort of healthy Chinese participants.A total of 1082 healthy participants aged from 41 to 70 years were included. sUA concentration was measured by the uricase-peroxidase method. SBP and DBP were assessed using mercury sphygmomanometry. Hypertension was defined as SBP ≥140 mm Hg or DBP ≥90 mm Hg. Hyperuricemia (HUA) was defined as sUA concentration of >7 mg/dL in men and >6 mg/dL in women. The association between sUA concentration and SBP and DBP was examined using Pearson's correlation test, multivariate linear regression, and logistic regression analysis.The prevalence of hypertension and HUA increased with age (P age, sex, total cholesterol, estimated glomerular filtration rate, and fasting plasma glucose). HUA was also a risk factor for hypertension in this age group (odds ratio 1.425, 95% confidence interval, 1.217-1.668, P age groups.In this population of healthy Chinese participants, sUA concentration was positively associated with hypertension only in the 41- to 50-year-old group. Lowering uric acid in this age group may help to reduce the incidence of hypertension. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

    To evaluate and compare the social cognition in patients with schizophrenia, healthy first-degree relatives and controls, by studying the relationship between social cognition and nonsocial cognition, psychopathology, and other clinical and sociodemographic variables. The total sample was comprised of patients diagnosed with paranoid schizophrenia (N = 29), healthy first-degree relatives (N = 21) and controls (N = 28). All groups were assessed with an ad hoc questionnaire and a Social Cognition Scale, which assessed the domains: emotional processing, social perception and attributional style in a Spanish population. The patient group was also assessed with the Scale for the Positive and Negative Syndrome Scale and the Mini-mental state examination. Statistical analyses were performed with SPSS version 15.0. Patients scored significantly worse in all domains of social cognition assessed, compared with controls, and mastery attributional style, compared with relatives. The type of psychopathology correlated negatively and statistically significantly with different domains of social cognition: negative symptoms with emotional processing and attributional style, and positive symptoms with social perception. Basic cognition scores correlated positively and statistically significantly with the domains social perception and attributional style. Social cognition has become an interesting object of study, especially in how it relates to non-social cognition, psychopathology and global functioning of patients, bringing new elements to be considered in the early detection, comprehensive treatment and psychosocial rehabilitation of patients. Its conceptualization as trait variable, the consideration of the existence of a continuum between patients and relatives are plausible hypotheses that require further research.

    Healthful eating and physical activity are important for healthy weight maintenance. The hypothesis for this study was that college-aged men would perceive factors affecting eating and physical activity as both contributing to and inhibiting healthy weight maintenance. The overall objective was to explore how men view weight maintenance in the context of these aspects. Subjects (n = 47, mean age = 20.3 +/- 1.7 years) completed an online survey, including the 51-item Three-Factor Eating Questionnaire, and participated in 1 of 6 focus groups. Three face-to-face and 3 online synchronous groups were conducted using a 15-question discussion guide to identify weight maintenance issues around eating, physical activity, and body perceptions. Weight satisfaction decreased with increase in both dietary restraint and disinhibition. Number of attempts to lose weight was positively associated with BMI (r [44] = .465, P = .01) and dietary restraint (r [44] = .515, P = .01). Findings from both focus group formats were similar. Motivators (sports performance/fitness, self-esteem, attractiveness, long-term health) were similar for eating healthfully and being physically active; however, more motivators to be physically active than to eat healthfully emerged. Enablers for eating healthfully included liking the taste, availability of healthful foods, using food rules to guide intake, having a habit of healthful eating, and internal drive/will. Barriers to healthful eating included fat in dairy foods, fruit and vegetable taste, and quick spoilage. Barriers to being physically active included lack of time/time management, obligations, being lazy, and girlfriends. Results may be used to inform future obesity prevention interventions.

    Survival prospects for adults with repaired tetralogy of Fallot (TOF) are now excellent. Attention should therefore shift to assessing and improving functional health status and quality of life. We aimed to assess late functional health status of adults surviving TOF repair by matched comparison to their healthy siblings. All 1,693 TOF repairs performed at our institution between 1946 and 1990 were reviewed. A matched comparison was undertaken whereby presumed survivors and their healthy sibling were contacted and asked to complete the Ontario Health Survey 1990 and the 36-Item Short Form Health Survey (SF-36) questionnaire. Both questionnaires were completed by 224 adult survivors and their sibling closest in age. Adults with repaired TOF had lower scores for self-perceived general health status (p health as good or excellent (p health (p = 0.001) than their siblings. However, patients reported similar satisfaction with their lives, similar levels of social participation and support, and were as likely to be in long-term partnerships. Worse physical and mental health scores were associated with older age at surgery and at time of questionnaire completion and recent requirement for noncardiac medication. Although reporting lower functional health status then their siblings, quality of life and life satisfaction for adults who underwent surgery for TOF during childhood is comparable to that of their siblings without heart defects. Follow-up of younger adults is required to understand current health outcomes attributable to improvements in the management of TOF. Copyright © 2012 The Society of Thoracic Surgeons.

    Full Text Available Severe aortic stenosis (AS is associated with the reduction of muscle mass and may be associated with deterioration of nutritional status. Furthermore, malnourished cardiac patients are characterized by a higher risk of postoperative complications and mortality. The aim of this study was the evaluation and comparison of nutritional status, appetite and body composition in older people with severe aortic stenosis before aortic valve replacement and healthy elderly volunteers. One hundred and one patients, aged >65 years old with severe AS were included in the study. Nutritional status was assessed. Body composition was estimated using bioelectrical impedance analysis. Concentrations of albumin, prealbumin, triglycerides, total cholesterol and C-reactive protein were measured, and a complete blood count was done. About 40% of AS patients were at risk of malnutrition. They had decreased hand grip strength and they lost more body mass than the control group. Malnourished AS patients were older, had lower body mass indexes (BMIs and lower aortic valve areas in comparison to well-nourished patients. Older AS patients, like their peers, show excessive body mass and, at the same time, the features of malnutrition. They have additional factors such as unintentional weight lost and decreased muscle strength which may be associated with worse outcomes.

Method: The research design was causal-comparative research design which is categorized as descriptive research method. The population included of all people who were referred to addiction treatment centers in Noor-Abad city (Delfan. The participants of the study comprised of 50 addicts under treatment and 50 healthy participants who were matched based on age, education level, social-economical status, and number of children selected by available sampling method. The alexithymia (TAS-20 and emotions control scales administered among both groups. Results: The results showed that there is a significant difference between addicts and non-addicts groups in terms of alexithymia and emotional control. In addition, difficulty in identifying of feelings, depression, anxiety and anger were the most important predictors of addiction severity. Conclusion: These results show that any difficulty in expressing emotions and disability in controlling of negative emotions (anger, depression, and anxiety are risk factors for substance abuse.

    Full Text Available Abstract: Interventions aimed at changing dietary patterns should be designed based on the main motives underlying the food choices of specific target populations. The aim of the present study was to identify motives underlying food choice and barriers to healthy eating among consumers in two socioeconomic levels in Uruguay. Eleven focus groups were carried out with a total of 76 participants. Six of the groups involved low income participants and the others were conducted with middle income participants. Discussions were held around frequently consumed products, motives underlying food choices and barriers to healthy eating. Results confirmed the strong influence of income level on motives underlying food choice and barriers to the adoption of healthy eating. Low income participants described their choices as mainly driven by economic factors and satiety, whereas convenience was the main determinant of food selection for middle income participants. Implications for the design of public policies targeted at each group are discussed.

    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 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.

    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, pguilt (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 (pguilt, 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.

    To compare the changes in the insulin reaction of Holstein dairy cows and Japanese Black cows (JB) during the periparturient period, the insulin resistance test in vivo and lymphocytes proliferation with insulin in vitro were performed. Ten healthy Holstein dairy cows (Holstein group) and 10 healthy JB cows (JB group) used in this study were observed on days 60, 40, and 20 before calving and days 7 and 20 after calving. In insulin resistance reaction in vivo and in vitro, a low insulin-stimulated glucose disposal rate and lymphocyte proliferation with insulin were observed in the Holstein group compared with the JB group during the experimental period. An analysis of the lymphocytes cultured with insulin showed that the percentage of CD4+CD45R- T cells in the Holstein group was significantly lower than that of the JB group before day 20. These findings indicate that T cells reaction to insulin in healthy periparturient Holstein cows is lower than that in Japanese Black.

    To compare CT lung volumetry (CTLV) measurements provided by different software packages, and to provide normative data for lung densitometric measurements in healthy individuals. This retrospective study included 51 chest CTs of 17 volunteers (eight men and nine women; mean age, 30 ± 6 years), who underwent spirometrically monitored CT at total lung capacity (TLC), functional residual capacity (FRC), and mean inspiratory capacity (MIC). Volumetric differences assessed by four commercial software packages were compared with analysis of variance (ANOVA) for repeated measurements and benchmarked against the threshold for acceptable variability between spirometric measurements. Mean lung density (MLD) and parenchymal heterogeneity (MLD-SD) were also compared with ANOVA. Volumetric differences ranged from 12 to 213 ml (0.20 % to 6.45 %). Although 16/18 comparisons (among four software packages at TLC, MIC, and FRC) were statistically significant (P < 0.001 to P = 0.004), only 3/18 comparisons, one at MIC and two at FRC, exceeded the spirometry variability threshold. MLD and MLD-SD significantly increased with decreasing volumes, and were significantly larger in lower compared to upper lobes (P < 0.001). Lung volumetric differences provided by different software packages are small. These differences should not be interpreted based on statistical significance alone, but together with absolute volumetric differences. (orig.)

    Previous research has established that a great deal of variation exists in the temporal sequence of swallowing events for healthy adults. Yet, the impact of aging on swallow event sequence is not well understood. Kendall et al. (Dysphagia 18(2):85-91, 2003) suggested there are 4 obligatory paired-event sequences in swallowing. We directly compared adherence to these sequences, as well as event latencies, and quantified the percentage of unique sequences in two samples of healthy adults: young ( 65). The 8 swallowing events that contribute to the sequences were reliably identified from videofluoroscopy in a sample of 23 healthy seniors (10 male, mean age 74.7) and 20 healthy young adults (10 male, mean age 31.5) with no evidence of penetration-aspiration or post-swallow residue. Chi-square analyses compared the proportions of obligatory pairs and unique sequences by age group. Compared to the older subjects, younger subjects had significantly lower adherence to two obligatory sequences: Upper Esophageal Sphincter (UES) opening occurs before (or simultaneous with) the bolus arriving at the UES and UES maximum distention occurs before maximum pharyngeal constriction. The associated latencies were significantly different between age groups as well. Further, significantly fewer unique swallow sequences were observed in the older group (61%) compared with the young (82%) (χ 2  = 31.8; p < 0.001). Our findings suggest that paired swallow event sequences may not be robust across the age continuum and that variation in swallow sequences appears to decrease with aging. These findings provide normative references for comparisons to older individuals with dysphagia.

    Full Text Available Abstract Background Overweight prevalence among Guatemalan girls is higher in public than in private schools. Little is known about adolescent girls’ perceptions of the right ways to achieve a healthy weight. This study examines public and private school adolescent girls’ perceptions of a “healthy weight,” and barriers and facilitators to achieving it. Methods We conducted 4 focus groups in public and private schools in Guatemala City with girls from 13 to 15 years old. The discussion guide included open-ended questions and activities aimed at examining perceptions of “healthy weight” and barriers and motivators to achieving it within the school environment. Focus groups were audio-recorded and transcribed. Data analyses followed established methods of content analysis. Results Twenty-eight girls (private school, n = 12; public school, n = 16 of ages ranging from 13.1 to 15.9 years (median, 14, IQR, 13.6–14.9 participated in the study. Girls identified images of thin and fit women as healthy. They cited healthy eating and physical activity as ways to achieve a healthy weight. Within the school environment, barriers to maintaining a healthy weight included a lack of healthy food options and the prioritization of sports for boys over girls. In public schools, facilities were less than optimal; in private schools, girls’ access to facilities was limited. Public school girls stated that their uniforms were inappropriate for exercising. Conclusion Our findings support the need to provide more healthy food options in Guatemalan schools. In addition, physical activity for girls should be promoted and facilities made available for their use.

    The conventional way to estimate functional networks is primarily based on Pearson correlation along with classic Fisher Z test. In general, networks are usually calculated at the individual-level and subsequently aggregated to obtain group-level networks. However, such estimated networks are inevitably affected by the inherent large inter-subject variability. A joint graphical model with Stability Selection (JGMSS) method was recently shown to effectively reduce inter-subject variability, mainly caused by confounding variations, by simultaneously estimating individual-level networks from a group. However, its benefits might be compromised when two groups are being compared, given that JGMSS is blinded to other groups when it is applied to estimate networks from a given group. We propose a novel method for robustly estimating networks from two groups by using group-fused multiple graphical-lasso combined with stability selection, named GMGLASS. Specifically, by simultaneously estimating similar within-group networks and between-group difference, it is possible to address inter-subject variability of estimated individual networks inherently related with existing methods such as Fisher Z test, and issues related to JGMSS ignoring between-group information in group comparisons. To evaluate the performance of GMGLASS in terms of a few key network metrics, as well as to compare with JGMSS and Fisher Z test, they are applied to both simulated and in vivo data. As a method aiming for group comparison studies, our study involves two groups for each case, i.e., normal control and patient groups; for in vivo data, we focus on a group of patients with right mesial temporal lobe epilepsy.

    To evaluate the impact of the University of Kentucky's Healthy Choices for Every Body (HCEB) adult nutrition education curriculum on participants' food resource management (FRM) skills and food safety practices. A quasi-experimental design was employed using propensity score matching to pair 8 intervention counties with 8 comparison counties. Independent-samples t tests and ANCOVA models compared gains in FRM skills and food safety practices between the intervention and comparison groups (n = 413 and 113, respectively). Propensity score matching analysis showed a statistical balance and similarities between the comparison and intervention groups. Food resource management and food safety gain scores were statistically significantly higher for the intervention group (P food safety practices of participants.

    Hypothesis testing involves posing both a null hypothesis and an alternative hypothesis. This basic statistical tutorial discusses the appropriate use, including their so-called assumptions, of the common unadjusted bivariate tests for hypothesis testing and thus comparing study sample data for a difference or association. The appropriate choice of a statistical test is predicated on the type of data being analyzed and compared. The unpaired or independent samples t test is used to test the null hypothesis that the 2 population means are equal, thereby accepting the alternative hypothesis that the 2 population means are not equal. The unpaired t test is intended for comparing dependent continuous (interval or ratio) data from 2 study groups. A common mistake is to apply several unpaired t tests when comparing data from 3 or more study groups. In this situation, an analysis of variance with post hoc (posttest) intragroup comparisons should instead be applied. Another common mistake is to apply a series of unpaired t tests when comparing sequentially collected data from 2 study groups. In this situation, a repeated-measures analysis of variance, with tests for group-by-time interaction, and post hoc comparisons, as appropriate, should instead be applied in analyzing data from sequential collection points. The paired t test is used to assess the difference in the means of 2 study groups when the sample observations have been obtained in pairs, often before and after an intervention in each study subject. The Pearson chi-square test is widely used to test the null hypothesis that 2 unpaired categorical variables, each with 2 or more nominal levels (values), are independent of each other. When the null hypothesis is rejected, 1 concludes that there is a probable association between the 2 unpaired categorical variables. When comparing 2 groups on an ordinal or nonnormally distributed continuous outcome variable, the 2-sample t test is usually not appropriate. The

    Folic acid deficiency is a risk factor for schizophrenia through epidemiology, biochemistry and gene-related studies. Compared with healthy people, schizophrenic patients may have high homocysteine plasma values and homocysteine or low levels of folic acid, which seems to correlate with extrapyramidal motor symptoms caused by neuroleptic therapy and with symptoms of schizophrenia. In this present study, we focus on the difference of folic acid level between schizophrenic patient and control group. The study sample consisted of schizophrenic patients and 14 people in the control group and performed blood sampling to obtain the results of folic acid levels. The folic acid level in both groups was within normal range, but the schizophrenic patient group had lower mean folic acid values of 5.00 ng/ml (sb 1.66), compared with the control group with mean folic acid values of 10.75 ng/ml (sb 4.33). there was the group of the control group had a higher value of folic acid than the schizophrenic group.

    Subjective health measurements are increasingly used in clinical research, particularly for patient groups comparisons. Two main types of analytical strategies can be used for such data: so-called classical test theory (CTT), relying on observed scores and models coming from Item Response Theory (IRT) relying on a response model relating the items responses to a latent parameter, often called latent trait. Whether IRT or CTT would be the most appropriate method to compare two independent groups of patients on a patient reported outcomes measurement remains unknown and was investigated using simulations. For CTT-based analyses, groups comparison was performed using t-test on the scores. For IRT-based analyses, several methods were compared, according to whether the Rasch model was considered with random effects or with fixed effects, and the group effect was included as a covariate or not. Individual latent traits values were estimated using either a deterministic method or by stochastic approaches. Latent traits were then compared with a t-test. Finally, a two-steps method was performed to compare the latent trait distributions, and a Wald test was performed to test the group effect in the Rasch model including group covariates. The only unbiased IRT-based method was the group covariate Wald's test, performed on the random effects Rasch model. This model displayed the highest observed power, which was similar to the power using the score t-test. These results need to be extended to the case frequently encountered in practice where data are missing and possibly informative.

    Dietary intervention studies are required to deeper understand the variability of gut microbial ecosystem in healthy dogs under different feeding conditions and to improve diet formulations. The aim of the study was to investigate in dogs the influence of a raw based diet supplemented with vegetable foods on faecal microbiome in comparison with extruded food. Eight healthy adult Boxer dogs were recruited and randomly divided in two experimental blocks of 4 individuals. Dogs were regularly fed a commercial extruded diet (RD) and starting from the beginning of the trial, one group received the raw based diet (MD) and the other group continued to be fed with the RD diet (CD) for a fortnight. After 14 days, the two groups were inverted, the CD group shifted to the MD and the MD shifted to the CD, for the next 14 days. Faeces were collected at the beginning of the study (T0), after 14 days (T14) before the change of diet and at the end of experimental period (T28) for DNA extraction and analysis of metagenome by sequencing 16SrRNA V3 and V4 regions, short chain fatty acids (SCFA), lactate and faecal score. A decreased proportion of Lactobacillus, Paralactobacillus (P diet significantly (P diet composition modifies faecal microbial composition and end products of fermentation. The administration of MD diet promoted a more balanced growth of bacterial communities and a positive change in the readouts of healthy gut functions in comparison to RD diet.

    Increased thoracic kyphosis is one of the most disfiguring consequences of osteoporotic spine fractures in the elderly. However, mechanisms involved in the increasing of the kyphosis degree among osteoporotic women are not completely understood. Then, the aims of this cross-sectional preliminary study were comparing thoracic kyphosis degree, trunk muscle peak torque and joint position sense among healthy and osteoporotic elderly women and investigating possible factors affecting the kyphosis degree. Twenty women were selected for 2 groups: healthy (n=10) and osteoporotic (n=10) elderly women. Bone mineral density (BMD), thoracic kyphosis degree, trunk muscles peak torque and joint position sense were measured. Differences among groups were analyzed by Student's Test T for unpaired data. Correlations between variables were performed by Pearson's coefficient correlation. The level of significance used for all comparisons was 5% (p≤0.05). We observed that the osteoporotic women demonstrated a significantly higher degree of kyphosis and lower trunk extensor muscle peak torque. Moreover, it was found that the BMD had a negative correlation with the thoracic kyphosis degree. Kyphosis degree showed a negative correlation between extensor muscle strength and joint position sense index. This study suggests that lower BMD may be associated to higher degree of kyphosis degree, lower trunk extensors muscle strength and an impaired joint position sense. It is also suggested that lower extensor muscle strength may be a factor that contributes to the increasing in kyphosis thoracic degree. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Kinesiologic elastic tape is widely used for both clinical and sport applications although its efficacy in enhancing agonistic performance is still controversial. Aim of the study was to verify in a group of healthy basketball players whether a neuromuscular taping application (NMT on ankle and knee joints could affect the kinematic and the kinetic parameters of the jump, either by enhancing or inhibiting the functional performance. Fourteen healthy male basketball players without any ongoing pathologies at upper limbs, lower limbs and trunk volunteered in the study. They randomly performed 2 sets of 5 counter movement jumps (CMJ with and without application of Kinesiologic tape. The best 3 jumps of each set were considered for the analysis. The Kinematics parameters analyzed were: knees maximal flexion and ankles maximal dorsiflexion during the push off phase, jump height and take off velocity. Vertical ground reaction force and maximal power expressed in the push off phase of the jump were also investigated. The NMT application in both knees and ankles showed no statistically significant differences in the kinematic and kinetic parameters and did not interfere with the CMJ performance. Bilateral NMT application in the group of healthy male basketball players did not change kinematics and kinetics jump parameters, thus suggesting that its routine use should have no negative effect on functional performance. Similarly, the combined application of the tape on both knees and ankles did not affect in either way jump performance.

    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.

    Full Text Available Abstract Background Parent carers of disabled children report poor physical health and mental wellbeing. They experience high levels of stress and barriers to engagement in health-related behaviours and with ‘standard’ preventive programmes (e.g. weight loss programmes. Interventions promoting strategies to improve health and wellbeing of parent carers are needed, tailored to their specific needs and circumstances. Methods We developed a group-based health promotion intervention for parent carers by following six steps of the established Intervention Mapping approach. Parent carers co-created the intervention programme and were involved in all stages of the development and testing. We conducted a study of the intervention with a group of parent carers to examine the feasibility and acceptability. Standardised questionnaires were used to assess health and wellbeing pre and post-intervention and at 2 month follow up. Participants provided feedback after each session and took part in a focus group after the end of the programme. Results The group-based Healthy Parent Carers programme was developed to improve health and wellbeing through engagement with eight achievable behaviours (CLANGERS – Connect, Learn, be Active, take Notice, Give, Eat well, Relax, Sleep, and by promoting empowerment and resilience. The manualised intervention was delivered by two peer facilitators to a group of seven parent carers. Feedback from participants and facilitators was strongly positive. The study was not powered or designed to test effectiveness but changes in measures of participants’ wellbeing and depression were in a positive direction both at the end of the intervention and 2 months later which suggest that there may be a potential to achieve benefit. Conclusions The Healthy Parent Carers programme appears feasible and acceptable. It was valued by, and was perceived to have benefited participants. The results will underpin future refinement of the

    Full Text Available ABSTRACT OBJECTIVE: To compare the biochemical and immunological profiles of pediatric patients with acute myeloid leukemia (AML with healthy children and adolescents. METHODS: 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. RESULTS: 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-a, IL-6, IL-10, and IFN-? 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. CONCLUSIONS: 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.

Some studies reveal that bilingualism is a contributing factor to the development of stuttering. Main objective of this study was comparison of linguistic knowledge in Kurdish (L1 and Farsi (L2 between bilingual stutterers and their normal peers. Materials & Methods: In this case-control and comparative study all of 31 Kurdish-Farsi bilingual stutterers from 4 and 5 grades in primary schools of Javanrood were selected as case group and 31 normal peers were selected as control group by Pairs Matching Method. The linguistic knowledge of two groups in L1 and L2 were evaluated and compared by analyzing the speech quality indices (speech fluency index, speech complexity index, type-token ratio in a sample of their spontaneous speech in Kurdish and Farsi. Data were analyzed by Independent -T-test and Mann-Whitney U. Results: In both Kordish and Farsi Language, Speech unfluency was more in stutterd students than normal group. Also, speech complexity, speech fluency and lexical diversity of stuttered students were less than normal group and there were significant differences between two groups in all speech indices (P<0.05. Conclusion: The linguistic knowledge of stuttered group was less than normal group in both Kordish and Farsi language. This finding confirms that level of language proficiency may be considered as a contributing factor to stuttering.

    The present study deals with the plausible association between the trace elemental imbalances and the emergence of valvular heart disease (VHD). A total of 14 elements including Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Pb, Sr and Zn in the scalp hair of VHD patients and healthy donors were analysed by flame atomic absorption spectrophometry employing wet acid digestion methodology. Median levels of Cu, Fe, Mg, Mn and Sr in the scalp hair of patients were significantly higher compared to those of the healthy donors, while the median concentrations of K and Na were found to be considerably higher in the scalp hair of the healthy donors. In addition, substantially elevated Cu/Zn value in patients indicated the prevalence of inflammatory processes inside the body. The correlation coefficients among the elements in the hair of VHD patients were significantly diverse compared to those of the healthy donors. Multivariate statistical methods showed noticeably dissimilar apportionment of the elements in the two groups. Variations in the elemental levels were also observed with gender, habitat, dietary/smoking habits and occupations of both donor groups. Overall, the study revealed significant imbalances among the essential and toxic elements in the scalp hair of VHD patients compared to those of the healthy subjects.

    To assess the preliminary effects of a new course entitled Freshman 5 to Thrive/COPE Healthy Lifestyles on the cognitive beliefs, knowledge, mental health outcomes, healthy lifestyle choices, physical activity, and retention of college freshmen. Measures included demographics, nutrition knowledge, healthy lifestyle beliefs, healthy lifestyle perceived difficulty, healthy lifestyle choices, Beck Youth Inventories-II (anxiety, depression, anxiety, and destructive behavior), step count via pedometer, and college retention. The experimental COPE (Creating Opportunities for Personal Empowerment) group had greater intentions to live a healthy lifestyle (p = .02) versus the comparison group. COPE students also significantly increased their physical activity (p = .003) from baseline to postintervention and had a higher college retention rate than students who did not take the course. In addition, there was a significant decrease in depressive and anxiety symptoms in COPE students whose baseline scores were elevated. The Freshman 5 to Thrive Course is a promising intervention that can be used to enhance healthy lifestyle behaviors and improve mental health outcomes in college freshmen. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

Objectives The aim of the present study was to compare personality characteristics and coping strategies between patients with MS and healthy controls. Materials and Methods The study sample included 55 patients with MS and 57 matched healthy control individuals. The data were gathered via a demographic form, the ways of coping questionnaire, and the NEO five-factor inventory. The data were analyzed by multivariate analysis of variance (MANOVA, Pearson’s correlation coefficient, and logistic regression. Results No significant differences in personality characteristics were observed between patients and healthy controls (all P > 0.05. Only the coping strategy subscale of Distancing was significant between patients and healthy controls (P 0.05. Only the Neuroticism personality trait and the Distancing coping strategy were predictive of group membership (i.e., healthy or patient. Conclusions Our study suggests that the personality traits of patients with MS and healthy individuals are not significantly different. Patients with MS are likely to use the same coping strategies as healthy individuals, except in the subscale of Distancing.

    This study aimed to explore differences between mothers with healthy weight versus overweight/obesity in a wide range of their reported child feeding practices and their reports of their children's eating behaviours. Mothers (N = 437) with a 2-6-year-old child participated. They comprised two groups, based on their BMI: healthy weight (BMI of 18.0–24.9, inclusive) or overweight/obese (BMI of 25.0 or more). All mothers provided demographic information and completed self-report measures of thei...

    Full Text Available Obesity has become a severe worldwide problem. Compared to healthy-weight individuals, obese individuals seem to show an increased sensitivity to tempting food. In the present study, we test the pre-exposure effect, which implies that consumption of tempting food is decreased after exposure to tempting food cues in a context of a task that discourages food consumption. Healthy-weight and obese-weight participants were recruited via social media and university channels. Participants took part in a scrabble task with either candy letters or foam letters and subsequently engaged in a taste test. Results showed that in healthy-weight participants, consumption was reduced after solving the scrabble task with candy letters in comparison to foam letters. In obese-weight participants, consumption was reduced in the condition using foam letters (in comparison with healthy-weight participants. The pre-exposure effect was replicated in healthy-weight participants, but could not be observed in participants with obesity, since consumption was reduced in general in this group. Our results suggest that more work should be done to understand how food nudges work in the context of obesity.

    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.

    There is evidence that financial incentive interventions, which include both financial rewards and also penalties, are effective in encouraging healthy behaviours. However, concerns about the acceptability of such interventions remain. We report on focus groups with a cross-section of adults from North East England exploring their acceptance of financial incentive interventions for encouraging healthy behaviours amongst adults. Such information should help guide the design and development of acceptable, and effective, financial incentive interventions. Eight focus groups with a total of 74 adults were conducted between November 2013 and January 2014 in Newcastle upon Tyne, UK. Focus groups lasted approximately 60 minutes and explored factors that made financial incentives acceptable and unacceptable to participants, together with discussions on preferred formats for financial incentives. Verbatim transcripts were thematically coded and analysed in Nvivo 10. Participants largely distrusted health promoting financial incentives, with a concern that individuals may abuse such schemes. There was, however, evidence that health promoting financial incentives may be more acceptable if they are fair to all recipients and members of the public; if they are closely monitored and evaluated; if they are shown to be effective and cost-effective; and if clear health education is provided alongside health promoting financial incentives. There was also a preference for positive rewards rather than negative penalties, and for shopping vouchers rather than cash incentives. This qualitative empirical research has highlighted clear suggestions on how to design health promoting financial incentives to maximise acceptability to the general public. It will also be important to determine the acceptability of health promoting financial incentives in a range of stakeholders, and in particular, those who fund such schemes, and policy-makers who are likely to be involved with the design

    Obstructive sleep apnea syndrome obstructive sleep apnea syndrome is associated with symptoms including habitual snoring, witness apnea and excessive daytime sleepiness. Also obstructive sleep apnea syndrome is related to some occupations which are needed attention for work accident. We aimed to determine the prevalence of snoring, witnessed apnea and excessive daytime sleepiness in coal workers and healthy adults in Zonguldak city center, and also evaluate the differences between these groups. This study consisted of 423 underground coal workers and 355 individuals living in centre of Zonguldak. Study and comparison group were chosen by nonstratified randomized sampling method. Data were collected by a questionnaire that included information regarding snoring, witnessed apnea and excessive daytime sleepiness. Mean age was 43.3 ± 6.05 years in miners and 44.3 ± 11.8 years in comparison group. In miners, snoring frequency was determined as 42.6%, witnessed apneas were 4.0%, and daytime sleepiness were 4.7%. In comparison group, these symptoms were 38.6%, 4.8% and 2.8% respectively. There were no statistical differences between coal workers and comparison group in these symptoms. Also snoring prevalence was higher in smoker miners. We found that major symptoms of obstructive sleep apnea syndrome in coal workers are similar to general population in Zonguldak. Further studies that constucted higher populations and with polysomnography are needed to evaluate these findings.

    Full Text Available BACKGROUND AND OBJECTIVE: In the medical world one of the most interaction between body and mind are related to coronary heart disease and it is a major cause of morbidity and mortality in the world. For this reason, identifying psychological risk factors in this context is necessary. In this regard, this study was performed with aimed to coping styles and quality of life in CHD patients and healthy individuals. METHODS: This study was a cross-sectional performed on 100 patients with coronary heart disease and 100 healthy subjects. Data was collected through Lazarus and Folkman coping styles questionnaires that included four problematic coping and  four emotion-focused coping style and quality of life of the World Health Organization in four aspects of  physical, psychological, environmental and social relationship with demographic characteristics were collected and compared. FINDINGS: The mean of direct confrontive coping style in patients (8.75±2.81 were significantly more than healthy individuals (7.95±2.86 (p=0.036, the mean of escape-avoidance coping style in patients (9.80±4.59 were significantly more than healthy individuals (8.38±4.25 (p=0.045, and was not found significant difference between two groups in Problem-focused coping style, Also there was a significant difference in quality of life between two groups, in the physical health domain (p=0.000, psychological domain(p=0.001, social relationship domain (p=0.007 and environmental domain (p=0.003. CONCLUSION: Result showed that the quality of life in CHD patients were lower than healthy individuals and CHD patients used direct confrontive coping style and escape-avoidance coping style, more than healthy individuals. Therefore this two styles can be considered as risk factors for CHD.

    Recent research has shown that individuals with certain neurological conditions demonstrate greater intraindividual variability on cognitive tasks compared to healthy controls. The present study investigated intraindividual variability in the domains of physical functioning and affect/stress in three groups: adults with mild head injuries, adults with moderate/severe head injuries, and healthy adults. Participants were assessed on 10 occasions and results indicated that (a) individuals with head injuries demonstrated greater variability in dominant finger dexterity and right grip strength than the healthy controls; (b) increased variability tended to be associated with poorer performance/report both within and across tasks; and (c) increased variability on one task was associated with increased variability on other tasks. The findings suggest that increased variability in physical function, as well as cognitive function, represents an indicator of neurological compromise.

    Adjusting to cancer requires effective cognitive and emotional processing. Written and verbal disclosure facilitate processing and have been studied independently in cancer survivors. Combined written and verbal expression may be more effective than either alone, particularly for patients with difficult to discuss or embarrassing side effects. Thus, the authors developed and tested the efficacy of a 12-session combined written and verbal expression group program for psychologically distressed colorectal cancer (CRC) patients. Forty post-treatment patients with CRC (stages I-III) identified as psychologically distressed using the Brief Symptom Inventory (BSI) were randomized to an intervention group (Healthy Expressions; n = 25) or standard care (control group; n = 15). Assessments were completed at baseline, Month 2, and Month 4 (postintervention). Primary outcomes were psychological functioning and quality of life (QOL). Most participants were women (63%), white (63%), and non-Hispanic (75%). The Healthy Expressions group demonstrated significantly greater changes in distress compared with the control group at Month 2 on the BSI Global Severity Index (GSI) and the Centers for Epidemiologic Studies Depression scale (CES-D) scores (P psychological functioning in CRC patients who reported experiencing distress. Findings demonstrate the program's feasibility and provide strong support for conducting a larger randomized trial. Copyright © 2011 American Cancer Society.

    Full Text Available Background: Pseudomonas aeruginosa may be colonized in different human tissues and result in some infections potentially. Thus, considering that these bacteria are resistance to most of the current antibiotics, an examination on pathogenesis mechanisms of such bacteria can be effective in controlling the infections developed by it.Materials and Methods: In this project, among 40 blood samples (20 healthy persons, 20 infants, an amount of 5 ml (2 ml in the infants heparinized blood was collected form each and then neutrophils were isolated by a standard method and were counted by neubauer lam. After culturing Pseudomonas bacteria in broth medium, some tubes with densities of 1, 2, 3 and 4 McFarland were prepared and the bacteria were isolated by centrifuge method with 3000rpm for 10 minutes and then its exotoxin were exposed to neutrophils of the groups under study. The effect of time and the bacteria count on the amount of the secreted toxin and in adjacency to neutrophils was measured.Results: There were 11 men and 9 women in the health group and the infants group consisted of 12 boys and 8 girls. Death cell percentage of neutrophils was 100% in the health group and 8.90% in the infants group. Percentage of bacterial growth in the medium 1 and 2 McFarland was zero; in the medium 3 McFarland, it was 12.5% in the healthy group and 1% in the infants group (p<0.10. The average rate of cell death in the minute 15th was different in two groups (68.5% in health group vs. 92.5% in the infants (p<0.0005. Conclusion: This study showed the effect of Pseudomonas bacteria on the development of early cell death in the infants very well. As it was shown, this effect is time-dependent and this cell death (apoptosis is occurred in the infants earlier than health people.

    Full Text Available Background: With the advent of DNA-based culture-independent techniques, a constantly growing number of Selenomonas phylotypes have been detected in patients with destructive periodontal diseases. However, the prevalence levels that have been determined in different studies vary considerably. Aim: The present study was undertaken to detect and compare the presence of Selenomonas sputigena in the subgingival plaque samples from generalized aggressive periodontitis (GAP, chronic generalized periodontitis, and periodontally healthy patients using conventional polymerase chain reaction (PCR technique. Materials and Methods: A total of 90 patients were categorized as periodontally healthy individuals (Group I, n = 30, chronic generalized periodontitis (Group II, n = 30, and GAP (Group III, n = 30. The clinical parameters were recorded and subgingival plaque samples were collected. These were then subjected to conventional PCR analysis.Statistical Analysis Used: Kruskal–Wallis ANOVA test was used for multiple group comparisons followed by Mann–Whitney U-test for pairwise comparison. Results: On comparison between three groups, all the clinical parameters were found to be statistically highly significant. Comparing Groups I-II and I-III, the difference in detection was found to be statistically highly significant whereas in Groups II-III, it was statistically nonsignificant. On comparison of S. sputigena detected and undetected patients to clinical parameters in various study groups, the difference was found to be nonsignificant. Conclusion:S. sputigena was found to be significantly associated with chronic and aggressive periodontitis. Although the difference in its detection frequency in both groups was statistically nonsignificant when compared clinically, S. sputigena was more closely associated with the GAP.

    To describe the motivators and barriers to the adoption of a healthy postpartum lifestyle after a pregnancy complicated by preeclampsia, intrauterine growth restriction, and/or gestational diabetes. Thirty-six women with complicated pregnancies participated in six focus-group interviews that aimed to explore the perceptions of modifiable determinants of postpartum lifestyle. Although women expressed that they intended to live a healthy postpartum lifestyle, it was generally not achieved. The motivators included improving their own current health condition as well as modeling a healthy lifestyle for their children. Important barriers were reported to be lack of knowledge, poor recovery, and lack of professional support after delivery. The reported motivators and barriers can be used to develop a postpartum lifestyle intervention.

    Full Text Available Blood grouping is a vital test in pre-transfusion testing. Both tube and gel agglutination assays are used for ABO grouping. The main object of this study was to compare ABO grouping and D typing on tube and gel agglutination assay in order to assess the efficacy of each technique. A total of 100 healthy blood donors irrespective of age and sex were included in this study. Results showed that there is no significant difference between these two techniques. However, in 10 samples it was detected that the reaction strength in serum ABO grouping by gel agglutination assay is varied by only one grade when compared to tube agglutination assay. Due to numerous positive effects of gel assay it is more beneficial to implement this technique in the setups where blood banks bear heavy routine work load.

    News about health disparities often compares health risks faced by different demographic groups. Does this social comparison produce a contrast effect? It was hypothesized that when two racial groups are compared, people would perceive the relatively more at-risk group to be more, and the less at-risk group to be less, at-risk than if the same risk information was presented without the comparative reference group. Three experiments with Black and White respondents tested effects of intergroup social comparison framing (SCF) on perceptions of risk for sexually transmitted infections and skin cancer. SCF (including one White and two Black disparity frames) did not raise respondents' perceived risk regarding the more at-risk racial group, but consistently lowered respondents' risk ratings for the less at-risk racial group. The finding that the same statistic was perceived differently in comparative and noncomparative contexts underscores the importance of considering effects of communication about disparities.

    The aim of the study is to identify the brain areas, which control the bladder storage by 99 Tc m -HMPAO SPECT with Neurological Statistical Image Analysis Software (NEUROSTAT). SPECT were performed on twenty-five patients with some storage symptoms of lower urinary tract, among which nineteen patients were with detrusor overactivity (DO) (Group II) and six patients were with normal detrusor function (Group III), and fifteen healthy volunteers (Group I). All the subjects were male and right-handed, and were scanned twice under two conditions: resting state and urine withholding state. NEUROSTAT was adopted to analyze the difference in rCBF between groups and states. The results were displayed on Z-score images at a significance threshold of P<0.05 with correction for multiple comparisons. No region reached significant threshold in comparison of Group II and III in resting state. There were significant increases in tracer activity in bilateral inferior frontal gyri and the right middle temporal gyrus in urine withholding state as compared with resting state in Group I and III (P<0.05 with correction for multiple comparisons, the corresponding Z value was more than 4.476 for Group I, more than 4.414 for Group III). Among the regions,the right inferior frontal gyrus was distinctly prominent at both Z-score and the extent. In Group II, only the left middle temporal gyrus and middle frontal gyrus were activated significantly in urine withholding state as compared with resting (P<0.05 with correction for multiple comparisons, the corresponding Z value was more than 4.35). The results indicated that bilateral inferior frontal gyri and the right middle temporal gyrus associated with the control of bladder storage.Especially, the right inferior frontal gyrus played a more important role in cerebral control of bladder storage, inhibiting the contraction of detrusor in urine storage.

    Objectives. We determined whether participation in Healthy Babies Healthy Start (HBHS), a maternal health program emphasizing racial equity and delivering services through case management home visitation, was associated with improved birth outcomes for Black women relative to White women. Methods. We used a matched-comparison posttest-only design in which we selected the comparison group using propensity score matching. Study data were generated through secondary analysis of Michigan state- and Kalamazoo County–level birth certificate records for 2008 to 2010. We completed statistical analyses, stratified by race, using a repeated-measures generalized linear model. Results. Despite their smoking rate being double that of their matched counterparts, Black HBHS participants delivered higher birth-weight infants than did Black nonparticipants (P = .05). White HBHS participants had significantly more prenatal care than did White nonparticipants, but they had similar birth outcomes (P = .7 for birth weight; P = .55 for gestation). Conclusions. HBHS participation is associated with increased birth weights among Black women but not among White women, suggesting differential program gains for Black women. PMID:24354844

    The objective of this study was to assess the interleukin 10 (IL-10) concentrations in the sera of dogs suffering from demodicosis. Twenty-six dogs were distributed into three groups: demodicosis groups G1, n=11 (recurring disease) and G2, n=6 (first time occurrence), and a control group, G3, n=9 (healthy dogs). All the animals were subjected to skin scrape tests and blood harvesting for serum extraction. In G1 and G2 only those animals with Demodex canis positive skin tests were included, while healthy dogs were included in G3. To assess IL-10 levels the commercial Quantikine Canine IL-10 Immunoassay(®) (R&D Systems) kit was used. The mean IL-10 level obtained for G1 was 269.4 pg/ml (sd=290.8 pg/ml), for G2 it was 28.5 pg/ml (sd=19.7 pg/ml) while the mean for G3 was 11.9 pg/ml (sd=2.3 pg/ml). There was a significant difference between G1 and the other two groups. According to our results, dogs with reoccurring demodicosis have higher IL-10 levels than healthy dogs and those suffering the disease for the first time. Copyright © 2012 Elsevier B.V.

    This study evaluated the effects of microcurrent application and 670 nm InGaP laser irradiation on wound healing in healthy and alloxan diabetic rats. The animals were divided into eight groups: healthy control (HC); diabetic control (DC); healthy treated with microcurrent (HMC); diabetic treated with microcurrent (DMC); healthy irradiated with laser (HL); diabetic irradiated with laser (DL); healthy receiving laser and microcurrent application (HLMC) and diabetic receiving laser and microcurrent application (DLMC). Wound samples were collected on days 2, 6, 10 and 14 of treatment for structural analysis, morphometry, and Western blotting to quantify the expression of TGF-β1 and VEGF. Comparison of animals receiving laser and microcurrent therapy showed a reduction in the number of inflammatory cells in diabetic animals, as well as an increase of fibroblasts in healthy animals and of newly formed vessels in healthy and diabetic animals. Expression of TGF-β1 was increased on day 6 in all groups, especially diabetic animals. A reduction in the expression of this protein was observed on day 10 in all groups. VEGF expression was higher on day 6 in treated and control diabetic animals when compared to healthy animals. Analysis of VEGF expression in the laser- and microcurrent-treated groups on day 10 showed a decrease in diabetic animals and an increase in healthy animals. In conclusion, laser therapy and microcurrent stimulation exert beneficial effects on wound healing in both healthy and diabetic animals. (paper)

    List learning is probably the most established paradigm for the psychometric evaluation of episodic memory deficits in different neuropsychiatric conditions including epilepsy. Strategies which are capable of increasing the test performance might be promising candidates for a therapeutic improvement of daily memory performance. Based on the classical 'temporal grouping effect' we wanted to evaluate the memory-enhancing potential of disentangling perceiving, rehearsing and encoding by temporally grouped presentation and group-wise reproduction during acquisition. According to the ethical principle of subsidiary the study was performed in healthy adolescents (N=126) before setting-up a patient study. Subjects had to learn a list of 12 semantically unrelated nouns and a list of 12 figures during two acquisition trials under one of four experimental conditions defined by the size of presented item groups (GS): GS=1 (single items, i.e., 12 x 1 item), GS=3 (4 x 3 items), GS=6 (2 x 6 items), and GS=12 (standard presentation mode, i.e., 1 x 12 items). Repeated measures MANOVA confirmed a positive effect of smaller GS on acquisition performance but the grouping condition obtained no effect on immediate and delayed free recall or on yes/no recognition. For verbal retention, GS=12 even showed a tendency toward an advantage as compared to GS=3. Although appearing reasonable and promising, facilitating acquisition during list learning by temporal grouping and grouped overt rehearsal turned out to be ineffective with regard to long-term memory encoding and retrieval. A strategy however which fails in healthy subjects is unlikely to obtain a therapeutic potential in patients with memory deficits.

  15. Multiloop integral system test (MIST): Final report, Inter-group comparisons

    1989-07-01

    The multiloop integral system test (MIST) was part of a multiphase program started in 1983 to address small-break loss-of-coolant accidents (SBLOCAs) specific to Babcock and Wilcox-designed plants. MIST was sponsored by the US Nuclear Regulatory Commission, the Babcock and Wilcox Owners Group, the Electric Power Research Institute, and Babcock and Wilcox. The unique features of the Babcock and Wilcox design, specifically the hot leg U-bends and steam generators, prevented the use of existing integral system data or existing integral system facilities to address the thermal-hydraulic SBLOCA questions. MIST and two other supporting facilities were specifically designed and constructed for this program, and an existing facility -- the once-through integral system (OTIS) -- was also used. Data from MIST and the other facilities will be used to benchmark the adequacy of system codes, such as RELAP5 and TRAC, for predicting abnormal plant transients. The individual tests are described in detail in Volumes 2 through 8 and Volume 11, and are summarized in Volume 1. Inter-group comparisons are addressed in this document, Volume 9. These comparisons are grouped as follows: mapping versus SBLOCA transients, SBLOCA, pump effects, and the effects of noncondensible gases.

    The continual exposure to unhealthy food cues in the environment encourages poor dietary habits, in particular consuming too much fat and sugar, and not enough fruit and vegetables. According to Berridge's (2009) model of food reward, unhealthy eating is a behavioural response to biased attentional processing. The present study used an established attentional bias modification paradigm to discourage the consumption of unhealthy food and instead promote healthy eating. Participants were 146 undergraduate women who were randomly assigned to two groups: one was trained to direct their attention toward pictures of healthy food ('attend healthy' group) and the other toward unhealthy food ('attend unhealthy' group). It was found that participants trained to attend to healthy food cues demonstrated an increased attentional bias for such cues and ate relatively more of the healthy than unhealthy snacks compared to the 'attend unhealthy' group. Theoretically, the results support the postulated link between biased attentional processing and consumption (Berridge, 2009). At a practical level, they offer potential scope for interventions that focus on eating well. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available OBJECTIVE:to compare physical performance and cardiorespiratory responses in the six-minute walk test (6MWT in asthmatic children with reference values for healthy children in the same age group, and to correlate them with intervening variables.METHODS:this was a cross-sectional, prospective study that evaluated children with moderate/severe asthma, aged between 6 and 16 years, in outpatient follow-up. Demographic and spirometric test data were collected. All patients answered the pediatric asthma quality of life (QoL questionnaire (PAQLQ and level of basal physical activity. The 6MWT was performed, following the American Thoracic Society recommendations. Comparison of means was performed using Student's t-test and Pearson's correlation to analyze the 6MWT with study variables. The significance level was set at 5%.RESULTS:40 children with moderate or severe asthma were included, 52.5% males, 70% with normal weight and sedentary. Mean age was 11.3 ± 2.1 years, mean height was 1.5 ± 0.1 m, and mean weight was 40.8 ± 12.6 Kg. The mean distance walked in the 6MWT was significantly lower, corresponding to 71.9% ± 19.7% of predicted values; sedentary children had the worst values. The difference between the distance walked on the test and the predicted values showed positive correlation with age (r = 0.373, p = 0.018 and negative correlation with cardiac rate at the end of the test (r = -0.518, p < 0.001. Regarding QoL assessment, the values in the question about physical activity limitations showed the worst scores, with a negative correlation with walked distance difference (r = -0.311, p = 0.051.CONCLUSIONS:asthmatic children's performance in the 6MWT evaluated through distance walked is significantly lower than the predicted values for healthy children of the same age, and is directly influenced by sedentary life style.

    Stress-relieving effects of balneotherapy compared to progressive muscle relaxation (PMR) and to resting were investigated by measuring subjective relaxation and salivary cortisol. It was also examined whether participants with a high versus low stress level would have a different relaxation response. A sample of healthy volunteers was randomized to balneotherapy, PMR, or a resting control group, each intervention lasting for 25 min. Pre- and post-intervention salivary cortisol samples were collected, and participants rated their status of relaxation on a quantitative scale. In addition, 3 questionnaires were applied to detect participants' stress level and bodily complaints. 49 healthy participants were recruited (65.3% female). In a pre-post comparison, salivary cortisol decreased (F = 23.53, p balneotherapy group rated themselves as more relaxed after the intervention as compared to the other groups (F = 5.22, p balneotherapy seems to be more beneficial with regard to subjective relaxation effects and similarly beneficial with regard to a decrease in salivary cortisol. © 2014 S.

    2006-09-01

    Despite the growing popularity of self-help groups for people with chronic illness, there has been surprisingly little research into how these may support adjustment to illness. This study investigated the role that social comparison, occurring within a self-help group, may play in adjustment to chronic illness. A model of adjustment based on control process theory and response shift theory was tested to determine whether social comparisons predicted adjustment after controlling for the catalyst for adjustment (disease severity) and antecedents (demographic and psychological factors). A sample of 301 people with Ménière's disease who were members of the Ménière's Society UK completed questionnaires at baseline and 10-month follow-up assessing adjustment, defined for this study as functional and goal-oriented quality of life. At baseline, they also completed measures of the predictor variables i.e. the antecedents (age, sex, living circumstances, duration of self-help group membership, self-esteem, optimism and perceived control over illness), the catalyst (severity of vertigo, tinnitus, hearing loss and fullness in the ear) and mechanisms of social comparison within the self-help group. The social comparison variables included the extent to which self-help group resources were used, and whether reading about other members' experiences induced positive or negative feelings. Cross-sectional results showed that positive social comparison was indeed associated with better adjustment after controlling for all the other baseline variables, while negative social comparison was associated with worse adjustment. However, greater levels of social comparison at baseline were associated with a deteriorating quality of life over the 10-month follow-up period. Alternative explanations for these findings are discussed.

    This article presents qualitative research findings of Section 8 landlord perceptions regarding healthy housing practices to inform landlord-focused initiatives. Approach or Design: Five focus groups were conducted with landlords. Boston, Massachusetts. Section 8 landlords participated in focus groups (n = 39). Focus group transcripts were coded for key themes using a grounded theory approach. Landlords' primary challenges to creating a healthy housing environment included tenant behavior, financial burden, and policy enforcement; tenant safety and cost savings were seen as primary benefits. Landlords play a critical role in implementing healthy housing practices. Several opportunities exist to reduce barriers and capitalize on perceived benefits of implementing these practices, including increasing access to educational and financial resources.

    Full Text Available Sleep problems are common complaints among pregnant women. This study was designed to compare subjective sleep problems in non-pregnancy condition, healthy and preeclamptic pregnancy as a major complication of pregnancy. We hypothesized that some sleep problems are more prevalent in females with preeclampsia.In this cross-sectional study, 102 women with preeclampsia, 106 healthy pregnant women in the third trimester and 103 healthy non-pregnant women were selected through random sampling. Age and parity were matched in the three groups. We used Global sleep assessment questionnaire (GSAQ to check the subjective sleep problems, and then we performed statistical analysis using Analysis of variance (ANOVA and Pearson Chi-square tests.Our findings revealed significant differences in initial insomnia (p = 0.034, fragmented sleep (p = 0.022, snoring (p<0.001, non-idiopathic insomnia (p = 0.045 and sadness and anxiety (p = 0.001 between the three groups. Some sleep problems were more common in preeclampctic compared to healthy pregnant women including initial insomnia, fragmented sleep, snoring, sleep apnea and non-idiopathic insomnia. Moreover, the subjects with preeclampsia revealed more fragmented sleep, snoring, sadness and anxiety and lack of getting enough sleep due to other activities compared to non-pregnant women.Different kinds of sleep problems can occur in subjects with preeclampsia in comparison with the non-pregnant and healthy pregnant subjects. Sleep problems should be evaluated during pregnancy, particularly in pregnant women with preeclampsia, and suitable treatment should be provided for any specific sleep problem.

    Stress is a major problem in today's fast-paced society and can lead to serious psychosomatic complications. The ancient Chinese mind-body exercise of Tai Chi may provide an alternative and self-sustaining option to pharmaceutical medication for stressed individuals to improve their coping mechanisms. The protocol of this study is designed to evaluate whether Tai Chi practice is equivalent to standard exercise and whether the Tai Chi group is superior to a wait-list control group in improving stress coping levels. This study is a 6-week, three-arm, parallel, randomized, clinical trial designed to evaluate Tai Chi practice against standard exercise and a Tai Chi group against a nonactive control group over a period of 6 weeks with a 6-week follow-up. A total of 72 healthy adult participants (aged 18-60 years) who are either Tai Chi naïve or have not practiced Tai Chi in the past 12 months will be randomized into a Tai Chi group (n = 24), an exercise group (n = 24) or a wait-list group (n = 24). The primary outcome measure will be the State Trait Anxiety Inventory with secondary outcome measures being the Perceived Stress Scale 14, heart rate variability, blood pressure, Short Form 36 and a visual analog scale. The protocol is reported using the appropriate Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) items. Copyright © 2014. Published by Elsevier B.V.

    Objectives The aim of this study was to evaluate the repeatability of quantitative sensory tests (QSTs) in a group of healthy untrained cats (n = 14) and to compare the results with those from cats with osteoarthritis (n = 7). Methods Peak vertical force (PVF) and vertical impulse were measured on a pressure plate system. Thermal sensitivity was assessed using a temperature-controlled plate at 7°C and 40°C. Individual paw lifts and overall duration of paw lifts were counted and measured for each limb. Paw withdrawal thresholds were measured using manual and electronic von Frey monofilaments (MVF and EVF, respectively) applied to the metacarpal or metatarsal pads. All measurements were repeated twice to assess repeatability of the tests. Results In healthy cats all tests were moderately repeatable. When compared with cats with osteoarthritis the PVF was significantly higher in healthy hindlimbs in repeat 1 but not in repeat 2. Cats with osteoarthritis of the forelimbs showed a decrease in the frequency of paw lifts on the 7°C plate compared with cats with healthy forelimbs, and the duration of paw lifts was significantly less than healthy forelimbs in the first repeat but not in the second repeat. Osteoarthritic limbs had significantly lower paw withdrawal thresholds with both MVF and EVF than healthy limbs. Conclusions and relevance QSTs are moderately repeatable in untrained cats. Kinetic gait analysis did not permit differentiation between healthy limbs and those with osteoarthritis, but thermal sensitivity testing (cold) does. Sensory threshold testing can differentiate osteoarthritic and healthy limbs, and may be useful in the diagnosis and monitoring of this condition in cats in the clinical setting.

    Full Text Available Background: Physical training is a useful method to reduce disease of cardiovascular, but the effect of exercise on the coagulation system is under investigation. The aim of this study was to determine the response of one bout exhaustive aerobic exercise and resistance training on some of coagulation markers in healthy young women.Materials and Method: This quasi-experimental research was performed in 2009. Twenty trained volunteer female students of physical education Sari Azad university were selected objectively and availability. The subjects were randomly divided into two groups of aerobic (n=10 and resistance training (n=10. Aerobic group performed an exhaustive workout program on treadmill intensity 65 to75% Vo2max on treadmill. The resistance group completed three sets of 5-7 repetitions of six exercises at an intensity corresponding to 80% of 1RM. Following 12 to 14 hours of nightly fasting, venous blood samples (5 cc were collected pre, immediately after exercise and after 60 min of recovery and analyzed for PT, aPTT and fibrinogen. Participants were matched according to anthropometric measurements, age and Vo2max. Hypothesizes were tested by using independent t, repeated measures and post-hoc test (p 0.05. Results: Both the aerobic and resistance training groups, PT time (p<0.001 and aPTT time significantly decreased (p=0.006, p<0.001 respectively times between the two groups and the effect of resistant training on fibrinogen level immediately after exercise. Also aPTT time higher increased after recovery in comparison with baseline levels in aerobic (p=0.006 and resistance training groups (p<0.001. There were no significant differences in PT and aPTT was higher than aerobic training (p=0.0035.Conclusion: The results show that both of acute aerobic and or anaerobic exercise lead to small and transit coagulation system and increase in coagulation times

    Full Text Available Abstract Background P-wave dispersion (Pd is a new ECG index used in human cardiology and veterinary medicine. It is defined as the difference between the maximum and the minimum P-wave duration recorded from multiple different ECG leads. So far no studies were performed assessing the importance of P-wave dispersion in dogs. Methods The current study was aimed at determining proper value of Pd in healthy dogs (group I, dogs with chronic valvular disease (group II and dogs with disturbances of supraventricular conduction (group III. The tests were carried out in 53 healthy dogs, 23 dogs with chronic valvular disease and 12 dogs with disturbances of supraventricular conduction of various breeds, sexes and body weight from 1,5 to 80 kg, aged between 0,5 and 17 years, submitted to the ECG examination. ECG was acquired in dogs in a standing position with BTL SD-8 electrocardiographic device and analyzed once the recording was enlarged. P-wave duration was calculated in 9 ECG leads (I, II, III, aVR, aVL, aVF, V1, V2, V4 from 5 cardiac cycles. Results The proper P-wave dispersion in healthy dogs was determined at up to 24 ms. P-wave dispersion was statistically significant increased (p Conclusions The P-wave dispersion is a constant index in healthy dogs, that is why it can be used for evaluating P wave change in dogs with chronic valvular disease and in dogs with disturbances of supraventricular conduction.

Therefore, 23 subjects (11 females and 12 males age 62 to 81 years; 13 patients with Alzheimer's disease (AD and 10 healthy elderly subjects (EHI with normal cognitive function participated in this study. people with Alzheimer's disease. healthy people was selected through some neurologist identified Short Portable Mental Status Questionnaire (SPMSQ. After obtaining the average number of correct counting of months of the year in both simple and difficult cognitive task the overall error (E or Root Mean Squared Error (RMSE, and variable error (VE were calculated for the tracking task. Then each person performed 10 tasks simultaneously (under Dual-task in both simple and difficult mode. Analysis of variance in cognitive tasks showed that there was a significant interaction between task difficulty and risk of AD (p0.05. In other words, at dual conditions of tracking task, accuracy and consistency of both groups was equally reduced, which was most prominent in difficult conditions. This decrease indicates increased interference at response level due to defects in the mechanisms of selective attention in dual cognitive and tracking tasks and both groups.

    Full Text Available It is generally believed that the infant's microbiota is established during the first 1-2 years of life. However, there is scarce data on its characterization and its comparison to the adult-like microbiota in consecutive years.To characterize and compare the intestinal microbiota in healthy young children (1-4 years and healthy adults from the North Carolina region in the U.S. using high-throughput bacterial phylogenetic microarray analysis.Detailed characterization and comparison of the intestinal microbiota of healthy children aged 1-4 years old (n = 28 and healthy adults of 21-60 years (n = 23 was carried out using the Human Intestinal Tract Chip (HITChip phylogenetic microarray targeting the V1 and V6 regions of 16S rRNA and quantitative PCR.The HITChip microarray data indicate that Actinobacteria, Bacilli, Clostridium cluster IV and Bacteroidetes are the predominant phylum-like groups that exhibit differences between young children and adults. The phylum-like group Clostridium cluster XIVa was equally predominant in young children and adults and is thus considered to be established at an early age. The genus-like level show significant 3.6 fold (higher or lower differences in the abundance of 26 genera between young children and adults. Young U.S. children have a significantly 3.5-fold higher abundance of Bifidobacterium species than the adults from the same location. However, the microbiota of young children is less diverse than that of adults.We show that the establishment of an adult-like intestinal microbiota occurs at a later age than previously reported. Characterizing the microbiota and its development in the early years of life may help identify 'windows of opportunity' for interventional strategies that may promote health and prevent or mitigate disease processes.

    The 'default-mode' network (DMN) has been investigated in the presence of various disorders, such as Alzheimer's disease and Autism spectrum disorders. More recently, this investigation has expanded to include patients with ischemic injury. Here, we characterized the effects of ischemic injury in terms of its spectral distribution of resting-state low-frequency oscillations and further investigated whether those specific disruptions were unique to the DMN, or rather more general, affecting the global cortical system. With 43 young healthy adults, 42 older healthy adults, 14 stroke patients in their early stage (system disruption may differ between healthy aging and following the event of an ischemic stroke. The stroke group in the later stage demonstrated a global reduction in the amplitude of the slow-5 oscillations (0.01-0.027 Hz) in the DMN as well as in the primary visual and sensorimotor networks, two 'task-positive' networks. In comparison to the young healthy group, the older healthy subjects presented a decrease in the amplitude of the slow-5 oscillations specific to the components of the DMN, while exhibiting an increase in oscillation power in the task-positive networks. These two processes of a decrease DMN and an increase in 'task-positive' slow-5 oscillations may potentially be related, with a deficit in DMN inhibition, leading to an elevation of oscillations in non-DMN systems. These findings also suggest that disruptions of the slow-5 oscillations in healthy aging may be more specific to the DMN while the disruptions of those oscillations following a stroke through remote (diaschisis) effects may be more widespread, highlighting a non-specificity of disruption on the DMN in stroke population. The mechanisms underlying those differing modes of network disruption need to be further explored to better inform our understanding of brain function in healthy individuals and following injury.

    Full Text Available Background: Haemophilus influenza (HI is the most commonly found pathogenic bacteria in pediatric otitis media and lower respiratory tract infections. Bacterial attachment to pharyngeal cells and proliferation may be necessary for infection. In the presence of human milk, attachment of HI to pharyngeal cells and colonization may be inhibited. To evaluate the protecting role of breast milk, we investigated the incidence of HI isolated from the throat of healthy infants with different feeding methods. Methods: Between August 2002 and March 2003, 210 healthy infants (70 purely breast-fed, 70 purely formula-fed, 70 mixed-fed, aged 1-6 months were enrolled into the study and a throat culture was taken in all of them. The incidence of HI was evaluated using Haemophilus Test Agar Bose (HTAB plates. Results: The incidence of HI in purely breast-fed, mixed-fed and purely formula-fed infants was 2.9%, 42.9% and 75.7% respectively (P = 0.000. The mean age and weight of cases in the three groups were not statistically different. Conclusion: These data suggest that human milk protects the throat of healthy infants from HI colonization especially in purely breast-fed cases.

    To compare qualitative magnetic resonance (MR) images and quantitative T2 measurements of the tibiotalar cartilage between ballerinas and healthy volunteers. Institutional review board approval for this study and informed consent (from all participants) were obtained. MR examinations were performed by using a 3-T MR imaging system with 21 professional female ballet dancers and 20 healthy female volunteers. Two musculoskeletal radiologists qualitatively measured tibiotalar cartilage T2 values in the anterior zones, middle zones, and posterior zones of cartilage. MR findings were also qualitatively analyzed in both groups. The tibial cartilage T2 values measured in the anterior and posterior zones and the talar cartilage T2 values measured in all three zones were significantly higher in the ballerina group than in the control group (P The posterior zones exhibited the highest T2 values among the three tibiotalar cartilage zones in both groups (P the presence of posterior soft-tissue edema (P = .001) and flexor hallucis longus tenosynovitis (P The findings showed a trend toward increasing cartilage T2 values in ballerinas when compared with control subjects, indicating that quantitative T2 measurement may potentially be used as a noninvasive imaging tool for early detection of cartilage lesions in the tibiotalar joint.

    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.

    To compare the thickness of the retinal nerve fibre layer (RNFL) in hydrophthalmic glaucomatous eyes in children with age-matched healthy controls using scanning laser polarimetry with variable corneal compensation (GDxVCC). Twenty hydrophthalmic eyes of 20 patients with the mean age of 10.64 ± 3.02 years being treated for congenital or infantile glaucoma were included in the analysis. Evaluation of RNFL thickness measured by GDxVCC in standard Temporal-Superior-Nasal-Inferior-Temporal (TSNIT) parameters was performed. The results were compared to TSNIT values of an age-matched control group of 120 healthy children published recently as referential values. The correlation between horizontal corneal diameter and RNFL thickness in hydrophthalmic eyes was also investigated. The mean ± SD values in TSNIT Average, Superior Average, Inferior Average and TSNIT SD in hydrophthalmic eyes were 52.3 ± 11.4, 59.7 ± 17.1, 62.0 ± 15.6 and 20.0 ± 7.8 μm, respectively. All these values were significantly lower compared to referential TSNIT parameters of age-matched healthy eyes (p = 0.021, p = 0.001, p = 0.003 and p = 0.018, respectively). A substantial number of hydrophthalmic eyes laid below the level of 5% probability of normality in respective TSNIT parameters: 30% of the eyes in TSNIT average, 50% of the eyes in superior average, 30% of the eyes in inferior average and 45% of the eyes in TSNIT SD. No significant correlation between enlarged corneal diameter and RNFL thickness was found. The mean values of all standard TSNIT parameters assessed using GDxVCC in hydrophthalmic glaucomatous eyes in children were significantly lower in comparison with referential values of healthy age-matched children. © 2011 The Authors.

    Mobile health (mHealth) programs hold great promise for increasing the reach of public health interventions. However, mHealth is a relatively new field of research, presenting unique challenges for researchers. A key challenge is understanding the relative effectiveness and cost of various methods of recruitment to mHealth programs. The objectives of this study were to (1) compare the effectiveness of various methods of recruitment to an mHealth intervention targeting healthy infant feeding practices, and (2) explore factors influencing practitioner referral to the intervention. The Growing healthy study used a quasi-experimental design with an mHealth intervention group and a concurrent nonrandomized comparison group. Eligibility criteria included: expectant parents (>30 weeks of gestation) or parents with an infant mobile phone, ≥18 years old, and living in Australia. Recruitment to the mHealth program consisted of: (1) practitioner-led recruitment through Maternal and Child Health nurses, midwives, and nurses in general practice; (2) face-to-face recruitment by researchers; and (3) online recruitment. Participants' baseline surveys provided information regarding how participants heard about the study, and their sociodemographic details. Costs per participant recruited were calculated by taking into account direct advertising costs and researcher time/travel costs. Practitioner feedback relating to the recruitment process was obtained through a follow-up survey and qualitative interviews. A total of 300 participants were recruited to the mHealth intervention. The cost per participant recruited was lowest for online recruitment (AUD $14) and highest for practice nurse recruitment (AUD $586). Just over half of the intervention group (50.3%, 151/300) were recruited online over a 22-week period compared to practitioner recruitment (29.3%, 88/300 over 46 weeks) and face-to-face recruitment by researchers (7.3%, 22/300 over 18 weeks). No significant differences were

    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.

    Full Text Available Introduction: Peri-implantitis is characterized by irreversible lesions that are caused by microbial plaque, involving not only the soft tissue around the implant, but also the implant-supporting bone. In the peri-implant diseases, some cytokines are increased, and inflammatory mediators, which are observed in peri-implantitis, induce the activation of osteoclasts and bone resorption. The aim of this study was to compare the level of interleukin 23 (IL-23 in patients with peri-implantitis and those with healthy peri-implant tissue. Materials & methods: This clinical trial was conducted on 19 patients with peri-implantitis and 19 patients with healthy peri-implant tissue. The samples were collected from sulcular fluid/gingival pocket fluid by paper cone and placed in vials. The level of IL-23 was determined using ELISA reader. Furthermore, the relationship of IL-23 levels with bleeding, probing depth, and pus formation was analyzed. Data analysis was performed using independent t-test, Pearson correlation coefficient, and Spearman test. Results: According to the results, the level of IL-23 in the patients with peri-implantitis was significantly higher than that in the group with healthy peri-implant tissue (P

    Full Text Available Hypothesis: Blood group antibodies are natural antibodies that develop early in life in response to cross-reactive environmental antigens in the absence of antigen encounter. Even later in life structural similarities in saccharide composition between environmental antigens such as bacterial polysaccharides and blood group A/B antigens could lead to changes in serum levels, IgM/IgG isotype and affinity maturation of blood group anti-A/B antibodies. We adressed the question whether immunization with pneumococcal polysaccharide (PnP vaccine (PPV Pneumovax®23 could have such an effect in patients with with type I diabetes mellitus (DM I, an autoimmune disease where an aberrant immune response to microbial antigens likely plays a role.Methods: Anti-PnP IgM and IgG responses were determined by ELISA and the Diamed-ID Micro Typing System was used to screen anti-A/B antibody titer before and after Pneumovax®23 immunization in 28 healthy individuals and 16 patients with DM I. In addition, surface plasmon resonance (SPR technology using the Biacore® device and a synthetic blood group A/B trisaccharide as the antigen was applied to investigate IgM and IgG anti-A/B antibodies and to measure antibody binding dynamics. Results: All healthy individuals and DM I patients responded with anti-PnP IgM and IgG antibody production four to six weeks after Pneumovax®23 (Pn23 immunization, while no increase in blood group anti-A/B antibody titer was observed when measured by the Diamed-ID Micro Typing System. Interestingly, isotype-specific testing by SPR-technology revealed an increase in blood group anti-A/B IgG, but not IgM, following Pn23 immunization in both patients and controls. No change in binding characteristics of blood group anti-A/B antibodies could be detected following Pn23 vaccination, supporting the assumption of an increase in IgG antibody titer with no or very little affinity maturation.Conclusion: The study provides evidence for epitope sharing

    Full Text Available Physical activity is known to significantly impact cardiometabolic health. Accelerometer data, as a measure of physical activity, can be used to objectively identify a disparity in movement (movement discordance between healthy and unhealthy adults. The purpose of this study was to examine the Movement Discordance between healthy and unhealthy adults in a large US population sample.Demographic, health and accelerometer data from the National Health and Nutrition Examination Study (NHANES 2003-2004 and 2005-2006 cohorts were used for this study. Participants were classified as either having a "normal" or "abnormal" value for each cardiometabolic health parameter examined, based on published criteria. Linear regression analyses were performed to determine significance of each abnormal health parameter (risk factor in its unique effect on the accelerometer counts, controlling for age and gender. Average accelerometer counts per minute (cpm by gender and age categories were estimated separately for the groups of normal and abnormal cardiometabolic risk.Average cpm for those with healthy levels of each individual cardiometabolic health parameter range from 296 cpm (for C reactive protein to 337 cpm (for waist circumference, while average cpm for those with abnormal levels of each individual cardiometabolic health parameter range from 216 cpm (for insulin to 291 cpm (for LDL-cholesterol. After controlling for age and gender, waist circumference, HbA1c, Insulin, Homocysteine, and HDL-Cholesterol were the cardiometabolic health parameters that showed significant, unique and independent effects on cpm. Overall, individuals who have abnormal values for all significant cardiometabolic health parameters ("unhealthy" averaged 267 cpm (SE = 15 cpm, while the healthy sample of this study averaged 428 cpm (SE = 10 cpm. The difference in cpm between the unhealthy and healthy groups is similar between males and females. Further, for both males and females, the

    Although the nipple and areola of the breast constitute a unique and prominent area on the chest, so far no study has been done on the functional properties of their skin surfaces. To study the stratum corneum (SC) covering the areola using noninvasive methods. Eighteen adult healthy subjects comprising nine men and nine women and 18 age- and sex-matched patients with atopic dermatitis (AD), none of whom had visible skin lesions, participated in the study. Transepidermal water loss (TEWL), skin surface hydration and skin surface lipid levels were measured on the areola and adjacent breast skin. The size of the skin surface corneocytes of these skin regions was assessed. All the healthy subjects showed significantly higher TEWL accompanied by smaller sized corneocytes on the areola than on the adjacent breast skin. Only female subjects revealed a significantly higher skin surface hydration state together with significantly increased skin surface lipid levels on the areola than on the adjacent breast skin. These sex differences were observed even in patients with AD. Comparison between healthy individuals and the patients with AD demonstrated higher TEWL, decreased skin surface hydration state and lower skin surface lipid levels associated with smaller sized corneocytes in the areola in the patients with AD, especially in male patients. In adults, the SC barrier function and SC water-binding capacity of the areola were functionally poorer than in the adjacent skin, being covered by smaller sized corneocytes and lower amounts of skin surface lipids, especially in men and in patients with AD. © 2011 The Authors.

    This study was conducted to determine the prevalence of virulence genes, serogroups, antimicrobial resistance and phylogenetic groups of Escherichia coli strains isolated from diarrheic and healthy camel calves in Tunisia. From 120 fecal samples (62 healthy and 58 diarrheic camel calves aged less than 3 months), 70 E. coli isolates (53 from diarrheic herds and 17 from healthy herds) were examined by PCR for detection of the virulence genes associated with pathogenic E. coli in animals. A significantly greater frequency of the f17 gene was observed in individual camels and in herds with diarrhea, this gene being found in 44.7% and 41.5% of isolates from camels and herds with diarrhea versus 22.5% and 11.7% in camels (p=0.05) and herds without diarrhea (p=0.02). The aida, cnf1/2, f18, stx2 and paa genes were found only in isolates from camels with diarrhea, although at a low prevalence, 1.8%, 3.7%, 1.8%, 3.7% and 11.3%, respectively. Prevalence of afa8, cdtB, eae, east1, iroN, iss, kpsMTII, paa, sfa, tsh and papC genes did not differ significantly between herds with or without diarrhea. Genes coding for faeG, fanC, f41, estI, estII, CS31a and eltA were not detected in any isolates. All isolates were sensitive to amikacin, chloramphenicol, ciprofloxacin, gentamicin and ceftiofur and the highest frequency of resistance was observed to tetracycline, and ampicillin (52.8% and 37.1% respectively). The phylogenetic groups were identified by conventional triplex PCR. Results showed that E. coli strains segregated mainly in phylogenetic group B1, 52.8% in diarrheic herds and 52.9% in healthy herds. Copyright © 2016 Elsevier Ltd. All rights reserved.

    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.

    Dilated cardiomyopathy (DCM) is the most common heart disease in Doberman Pinschers. MicroRNAs (miRNAs) are short non-coding RNAs playing important roles in gene regulation. Different miRNA expression patterns have been described for DCM in humans and might represent potential diagnostic markers. There are no studies investigating miRNA expression profiles in canine DCM. The aims of this study were to screen the miRNA expression profile of canine serum using miRNA microarray and to compare expression patterns of a group of Doberman Pinschers with DCM and healthy controls. Eight Doberman Pinschers were examined by echocardiography and 24-hour-ECG and classified as healthy (n=4) or suffering from DCM (n=4). Total RNA was extracted from serum and hybridized on a custom-designed 8x60k miRNA microarray (Agilent) containing probes for 1368 individual miRNAs. Although total RNA concentrations were very low in serum samples, 404 different miRNAs were detectable with sufficient signal intensity on miRNA microarray. 22 miRNAs were differentially expressed in the two groups (p1.5), but did not reach statistical significance after multiple testing correction (false discovery rate adjusted p>0.05). Five miRNAs were selected for further analysis using quantitative Real-Time RT-PCR (qPCR) assays. No significant differences were found using specific miRNA qPCR assays (p>0.05). Numerous miRNAs can be detected in canine serum. Between healthy and DCM dogs, miRNA expression changes could be detected, but the results did not reach statistical significance most probably due to the small group size. miRNAs are potential new circulating biomarkers in veterinary medicine and should be investigated in larger patient groups and additional canine diseases.

    Rheumatoid arthritis (RA) and chronic periodontitis are the most common chronic inflammatory diseases with significant pathological and clinical similarities. Numerous studies have indicated a relationship between rheumatoid arthritis and periodontal disease. The aim of this study was to compare the TNF-α levels in saliva among patients with Rheumatoid arthritis (RA) and chronic periodontitis as well as healthy subjects. One hundred and seventy-one patients were enrolled in this cross-sectional study. Fifty-seven patients diagnosed of RA, 57 patients with chronic periodontitis and 57 healthy subjects. These patients have been examined with regard to TNF-α level from salivary samples. Their teeth were examined with regard to Plaque Index , Gingival Index, probing depth and clinical attachment level.All patients were non-smokers. The results revealed a significant difference in all periodontal parameters among the three groups. The chronic periodontitis group showed a significantly higher value in all clinical periodontal parameters in comparison to both the RA and healthy groups. No significant difference was found between salivary TNF-α level among the three study groups. Patients with chronic periodontitis had the highest periodontal indices. However there was no significant difference regarding the level of salivary TNF-α. Hence, suppression of proinflammatory cytokines might prove beneficial in suppressing periodontal diseases among RA patients.

    Full Text Available The aim of the study was to characterize the presence of diverse CD4 and CD8 T cell subsets and regulatory cells in peripheral blood and lower oesophageal sphincter (LES from a young patient with BE/achalasia without treatment versus achalasia group. In order to characterize the circulating cells in this patient, a cytometric analysis was performed. LES tissue was evaluated by double-immunostaining procedure. Five healthy blood donors, 5 type achalasia patients, and 5 oesophagus tissue samples (gastrooesophageal junction from transplant donors were included as control groups. A conspicuous systemic inflammation was determined in BE/achalasia patient and achalasia versus healthy volunteer group. Nonetheless, a predominance of Th22, Th2, IFN-α-producing T cells, Tregs, Bregs, and pDCregs was observed in BE/achalasia patient versus achalasia group. A low percentage of Th1 subset in BE/achalasia versus achalasia group was determined. A noticeable increase in tissue of Th22, Th17, Th2, Tregs, Bregs, and pDCregs was observed in BE/achalasia versus achalasia group. Th1 subset was lower in the BE/achalasia patient versus achalasia group. This study suggests that inflammation is a possible factor in the pathogenesis of BE/achalasia. Further research needs to be performed to understand the specific cause of the correlation between BE and achalasia.

    Several research groups have proposed the electrical impedance tomography (EIT) in order to analyse lung ventilation. With the use of 16 electrodes, the EIT is capable to obtain a set of transversal section images of thorax. In previous works, we have obtained an alternating signal in terms of impedance corresponding to respiration from EIT images. Then, in order to transform those impedance changes into a measurable volume signal a set of calibration equations has been obtained. However, EIT technique is still expensive to attend outpatients in basics hospitals. For that reason, we propose the use of electrical bioimpedance (EBI) technique to monitor respiration behaviour. The aim of this study was to obtain a set of calibration equations to transform EBI impedance changes determined at 4 different frequencies into a measurable volume signal. In this study a group of 8 healthy males was assessed. From obtained results, a high mathematical adjustment in the group calibrations equations was evidenced. Then, the volume determinations obtained by EBI were compared with those obtained by our gold standard. Therefore, despite EBI does not provide a complete information about impedance vectors of lung compared with EIT, it is possible to monitor the respiration. (paper)

    Full Text Available Objective: Fatigue process in patients with neck pain was happened more quickly than healthy persons and neck muscle fatigue increased body sway during standing, but there is less evidence about the behavior of these muscles in dynamic conditions such as external perturbation, so this study was done to investigate the effect of muscle fatigue on onset latency of upper trapezius muscle in posterior-anterior perturbation among patients with chronic neck pain and healthy individuals. Materials & Methods: In this quasi experimental and interventional study 16 patients with chronic neck pain (intervention group and 16 healthy individuals (control group were selected by simple and convenient sampling and based on inclusive and exclusive criteria. Data collection was done by using questionnaire and doing some tests and the main equipments were dynamometer, accelerometer and surface electromyography. The weight equal to 30% of maximum voluntary contraction used to produce fatigue process and 10% of body weight used to produce perturbation. Independent T test, Paired T test and Repeated ANOVA were used for data analysis. Results: There was significant difference in onset latency of upper Trapezius muscle in posterior – anterior perturbation between two groups, before (P=0.006 and after (P=0.026 fatigue. This means that the onset latency was increased in healthy individuals and decreased in patients after fatigue. Also, there was significant difference in onset latency of Trapezius muscle in posterior – anterior perturbation between before and after fatigue in patients group (P<0.001 and healthy persons group (P=0.04. Conclusion: Pain can change the onset latency of trapezius muscle and possibly it can decrease muscle activity in deep muscle and change the pattern of muscle activation. Fatigue as an exaggerated risk factor can decrease onset latency of superficial muscle in patients with chronic neck pain to stabilize the system, that it can increase

  14. Are there healthy obese?

    Griera Borrás, José Luis; Contreras Gilbert, José

    2014-01-01

    It is currently postulated that not all obese individuals have to be considered as pathological subjects. From 10% to 20% of obese people studied do not show the metabolic changes common in obese patients. The term "healthy obese" has been coined to refer to these patients and differentiate them from the larger and more common group of pathological obese subjects. However, the definition of "healthy obese" is not clear. Use of "healthy obese" as a synonym for obese without metabolic complications is risky. Clinical markers such as insulin resistance are used to identify this pathology. It is not clear that healthy obese subjects have lower morbidity and mortality than pathologically obese patients. According to some authors, healthy obese would represent an early stage in evolution towards pathological obesity. There is no agreement as to the need to treat healthy obese subjects.

    Epithermal neutron beams are being developed for the application of boron neutron capture therapy (BNCT) of deep seated tumors, like glioblastoma and astrocytomas, through the intact skin. Epithermal neutrons will be moderated by the tissue mass between skin and tumour to produce the thermal neutrons necessary for the 10 B(n,α) 7 Li reaction in the target tissue. Although the neutron capture cross-sections of elements in normal tissue are several orders of magnitude lower that for boron, the high abundance of hydrogen and nitrogen will cause a significant contribution to the total absorbed radiation dose through the 1 H(n,γ) 2 H and the 14 N(n,p) 14 C reaction, respectively. Due to inevitable incomplete filtration, an epithermal beam will also contain a fast neutron component, i.e. neutrons with energies ≥ 10 keV, and a γ-photon component originating from the reactor and produced in structural and filter materials. Therefore, the resultant radiation consists of a complex of low and high LET radiation of which the constitutents vary rapidly with depth in tissue. Based on the ongoing canine healthy tissue tolerance study at the Brookhaven Medical Research Reactor (BMRR) using the epithermal beam without BSH, the relative biological effectiveness (RBE) of the fast neutron beam component has been determined for skin reactions. In addition, a open-quotes compound factorclose quotes, i.e geometry x RBE, for the 10 B(n,α) 7 Li reaction was derived for dogs irradiated at the BMRR with the epithermal beam and BSH (Gavin et al.). Currently, a healthy tissue tolerance study with BSH is being carried out at the HB11 epithermal beam of the High Flux Reactor at Petten. The present paper describes preliminary dose effect comparisons between High Flux Reactor (HFR) and BMRR irradiated dogs with respect to healthy tissue tolerance in order to refine the BSH compound factors and the fast neutron RBE for skin and brain

    We aim to develop robust estimates of disability-free life expectancy (DFLE) and healthy life expectancy (HLE) for ethnic groups in England and Wales in 2001 and to examine observed variations across ethnic groups. DFLE and HLE by age and gender for five-year age groups were computed for 16 ethnic groups by combining the 2001 Census data on ethnicity, self-reported limiting long-term illness and self-rated health using mortality by ethnic group estimated by two methods: the Standardised Illness Ratio (SIR) method and the Geographically Weighted Method (GWM). The SIR and GWM methods differed somewhat in their estimates of life expectancy (LE) at birth but produced very similar estimates of DFLE and HLE by ethnic group. For the more conservative method (GWM), the range in DFLE at birth was 10.5 years for men and 11.9 years for women, double that in LE. DFLE at birth was highest for Chinese men (64.7 years, 95% CI 64.0-65.3) and women (67.0 years, 95% CI 66.4-67.6). Over half of the ethnic minority groups (men: 10; women: 9) had significantly lower DFLE at birth than White British men (61.7 years, 95% CI 61.7-61.7) or women (64.1 years, 95% CI 64.1-64.2), mostly the Black, Asian and mixed ethnic groups. The lowest DFLE observed was for Bangladeshi men (54.3 years, 95% CI 53.7-54.8) and Pakistani women (55.1 years, 95% CI 54.8-55.4). Notable were Indian women whose LE was similar to White British women but who had 4.3 years less disability-free (95% CI 4.0-4.6). Inequalities in DFLE between ethnic groups are large and exceed those in LE. Moreover, certain ethnic groups have a larger burden of disability that does not seem to be associated with shorter LE. With the increasing population of the non-White British community, it is essential to be able to identify the ethnic groups at higher risk of disability, in order to target appropriate interventions.

    To examine the impact of a healthy lifestyle on stroke risk in men at higher risk of stroke because of other cardiovascular diseases or conditions. Our study population comprised 11,450 men in the Cohort of Swedish Men who had a history of hypertension, high cholesterol levels, diabetes, heart failure, or atrial fibrillation. Participants had completed a questionnaire about diet and lifestyle and were free from stroke and ischemic heart disease at baseline (January 1, 1998). We defined a healthy lifestyle as a low-risk diet (≥5 servings/d of fruits and vegetables and 0 to ≤30 g/d). Ascertainment of stroke cases was accomplished through linkage with the National Inpatient Register and the Swedish Cause of Death Register. During a mean follow-up of 9.8 years, we ascertained 1,062 incident stroke cases. The risk of total stroke and stroke types decreased with increasing number of healthy lifestyle factors. The multivariable relative risk of total stroke for men who achieved all 5 healthy lifestyle factors compared with men who achieved 0 or 1 factor was 0.28 (95% confidence interval 0.14-0.55). The corresponding relative risks (95% confidence interval) were 0.31 (0.15-0.66) for ischemic stroke and 0.32 (0.04-2.51) for hemorrhagic stroke. A healthy lifestyle is associated with a substantially reduced risk of stroke in men at higher risk of stroke. © 2015 American Academy of Neurology.

    It has been debated whether different diets are more or less effective in long-term weight loss success and cardiovascular disease prevention among men and women. To further explore these questions, the present study evaluated the combined effects of a high-protein, intermittent fasting, low-calorie diet plan compared with a heart healthy diet plan during weight loss, and weight loss maintenance on blood lipids and vascular compliance of obese individuals. The experiment involved 40 obese adults (men, n = 21; women, n = 19) and was divided into two phases: (a) 12-week high-protein, intermittent fasting, low-calorie weight loss diet comparing men and women (Phase 1) and (b) a 1-year weight maintenance phase comparing high-protein, intermittent fasting with a heart healthy diet (Phase 2). Body weight, body mass index (BMI), blood lipids, and arterial compliance outcomes were assessed at weeks 1 (baseline control), 12 (weight loss), and 64 (12 + 52 week; weight loss maintenance). At the end of weight loss intervention, concomitant reductions in body weight, BMI and blood lipids were observed, as well as enhanced arterial compliance. No sex-specific differences in responses were observed. During phase 2, the high-protein, intermittent fasting group demonstrated a trend for less regain in BMI, low-density lipoprotein (LDL), and aortic pulse wave velocity than the heart healthy group. Our results suggest that a high-protein, intermittent fasting and low-calorie diet is associated with similar reductions in BMI and blood lipids in obese men and women. This diet also demonstrated an advantage in minimizing weight regain as well as enhancing arterial compliance as compared to a heart healthy diet after 1 year.

    Manifestations of cystic fibrosis in the pancreas are gaining in clinical importance as patients live longer. Conventional ultrasonography and point shear wave elastography (pSWE) imaging are non-invasive and readily available diagnostic methods that are easy to perform. The aim of this study was to perform conventional ultrasonography and obtain pSWE values in the pancreases of patients with cystic fibrosis and to compare the findings with those of healthy controls. 27 patients with cystic fibrosis (13 women/14 men; mean age 27.7 ± 13.7 years; range 9-58 years) and 60 healthy control subjects (30 women/30 men; mean age 30.3 ± 10.0 years; range 22-55 years) underwent examinations of the pancreas with conventional ultrasound and pSWE imaging. Patients with cystic fibrosis have an echogenic pancreatic parenchyma. We found cystic lesions of the pancreas in six patients. pSWE imaging of the pancreatic parenchyma gave significantly lower shear wave velocities in patients with cystic fibrosis than in the control group (1.01 m/s vs 1.30 m/s; p cystic fibrosis than in a healthy control population.

    Osteoporosis and periodontitis are two separate diseases with different origins and manifestations. It is believed that these diseases linked together, because they both lead to bone damage, some risk factors are similar, they both have the highest prevalence in middle-aged and older women. Some studies showed that the use of panoramic radiography and special indices could be reliable tools for osteoporosis screening. This study was performed to evaluate the relationship between periodontal disease and jaw osteoporotic indices. Eighty-two patients with chronic periodontitis and 80 healthy individuals were selected, they had been referred to a private oral and maxillofacial radiology clinic to take a panoramic radiograph. Then panoramic indicators; including the mandibular cortical index (MCI), mental index (MI), and panoramic mandible index (PMI) in both groups were measured, recorded and analyzed. The mean age of investigated individuals was 39/8 ± 9/33. 58.6% of participants were females and 41.4% were males. MI and PMI levels in the periodontal group were more than the periodontally healthy group, but the differences between the two groups was not statistically significant (p = 0.808 and p = 0.102 respectively). The MCI level was significantly different between two groups (p = 0.028). The results of this study showed that there is significant relationship between MCI in panoramic radiography and chronic periodontitis. It is suggested to perform more studies to confrm if this index could be used for screening and indicating of bone status in high risk individuals. This study did not show a strong evidence of a relationship between osteoporosis and periodontitis. Since panoramic radiographs are routinely used for screening in dental practice, any association between radiomorphometric indices of mandible in periodontitis patients might be useful in prediction of osteoporosis in patients referring to dental clinics.

    Full Text Available The ‘default-mode’ network (DMN has been investigated in the presence of various disorders, such as Alzheimer’s disease and Autism spectrum disorders. More recently, this investigation has expanded to include patients with ischemic injury. Here, we characterized the effects of ischemic injury in terms of its spectral distribution of resting-state low-frequency oscillations and further investigated whether those specific disruptions were unique to the DMN, or rather more general, affecting the global cortical system. With 43 young healthy adults, 42 older healthy adults, 14 stroke patients in their early stage (< 7 days after stroke onset, and 16 stroke patients in their later stage (between 1-6 months after stroke onset, this study showed that patterns of cortical system disruption may differ between healthy aging and following the event of an ischemic stroke. The stroke group in the later stage demonstrated a global reduction in the amplitude of the slow-5 oscillations (0.01-0.027 Hz in the DMN as well as in the primary visual and sensorimotor networks, two ‘task-positive’ networks. In comparison to the young healthy group, the older healthy subjects presented a decrease in the amplitude of the slow-5 oscillations specific to the components of the DMN, while exhibiting an increase in oscillation power in the task-positive networks. These two processes of a decrease DMN and an increase in ‘task-positive’ slow-5 oscillations may potentially be related, with a deficit in DMN inhibition, leading to an elevation of oscillations in non-DMN systems. These findings also suggest that disruptions of the slow-5 oscillations in healthy aging may be more specific to the DMN while the disruptions of those oscillations following a stroke through remote (diaschisis effects may be more widespread, highlighting a non-specificity of disruption on the DMN in stroke population. The mechanisms underlying those differing modes of network disruption need

    Appropriate footwear for individuals with diabetes but no ulceration history could reduce the risk of first ulceration. However, individuals who deem themselves at low risk are unlikely to seek out bespoke footwear which is personalised. Therefore, our primary aim was to investigate whether group-optimised footwear designs, which could be prefabricated and delivered in a retail setting, could achieve appropriate pressure reduction, or whether footwear selection must be on a patient-by-patient basis. A second aim was to compare responses to footwear design between healthy participants and people with diabetes in order to understand the transferability of previous footwear research, performed in healthy populations. Plantar pressures were recorded from 102 individuals with diabetes, considered at low risk of ulceration. This cohort included 17 individuals with peripheral neuropathy. We also collected data from 66 healthy controls. Each participant walked in 8 rocker shoe designs (4 apex positions × 2 rocker angles). ANOVA analysis was then used to understand the effect of two design features and descriptive statistics used to identify the group-optimised design. Using 200 kPa as a target, this group-optimised design was then compared to the design identified as the best for each participant (using plantar pressure data). Peak plantar pressure increased significantly as apex position was moved distally and rocker angle reduced ( p  footwear which was individually selected. In terms of optimised footwear designs, healthy participants demonstrated the same response as participants with diabetes, despite having lower plantar pressures. This is the first study demonstrating that a group-optimised, generic rocker shoe might perform almost as well as footwear selected on a patient by patient basis in a low risk patient group. This work provides a starting point for clinical evaluation of generic versus personalised pressure reducing footwear.

    The caste issue dominates a large part of India's social and political life. Caste shapes one's identity. Furthermore, strong tensions exist between castes. Using subjective well-being data, we assess the role economic comparisons play in this society. We focus on both within and between-castes comparisons. Within-caste comparisons appear to reduce well-being. Comparisons between rival castes are found to decrease well-being three times more. We link these results to two models in which econo...

    Eat Smart! Ontario's Healthy Restaurant Program is a standard provincial health promotion program. Public health units give an award of excellence to restaurants that meet nutrition, food safety, and non-smoking seating standards. The purpose of this study was to determine why some restaurant operators have not applied to participate in the program, and how to get them to apply. Four focus group interviews were conducted with 35 operators who didn't apply to participate. The analysis of responses yielded various themes. The participants' perceived barriers to participation were misunderstandings about how to qualify for the program, lack of time, concern about different non-smoking bylaw requirements, and potential loss of revenue. Their perceived facilitators to participation were convenience of applying to participate, franchise executives' approval to participate, a 100% non-smoking bylaw, flexibility in the assessment of restaurants, the opportunity for positive advertising, alternative payment for food handler training, and customer demand. Program staff can use the findings to develop and use strategies to encourage participation.

    Objectives Little is known about the antecedents to dietary and physical activity behaviours that can support healthy gestational weight gain (GWG) across different weight status groups in pregnancy. The aim of this study was to use constructs common to dominant health behaviour theories to determine if predisposing, reinforcing and enabling factors for healthy eating, physical activity and weight gain differed between healthy and overweight pregnant women. Methods Pregnant women (n = 664) aged 29 ± 5 (mean ± SD) years were recruited at 16 ± 2 weeks gestation. Measures were self-reported pre-pregnancy weight, psychosocial constructs for healthy eating, physical activity and GWG and demographic data. Height was measured at 16 weeks. Psychosocial constructs were compared between women with pre-pregnancy weight status of healthy (BMI healthy eating and physical activity were not different between healthy (66 %) and overweight (34 %) women. Overweight women had lower self-efficacy for healthy eating, physical activity and GWG (p healthy eating (p = 0.002), and physical activity (p = 0.006). Conclusions for practice Both healthy and overweight women appear motivated to follow a healthy diet, exercise and avoid excess gestational weight during pregnancy. However many psychosocial factors associated with achieving these goals were different between healthy and overweight women. Health behaviour interventions tailored to overweight pregnant women should consider improving self-efficacy, providing support to overcome perceived barriers, validate positive changes made, and assist in managing negative expectations.

    Current research shows that online support groups can offer people affected by infertility a unique and valuable source of social support. However, to date most research has focused on the experiences of people who post messages to online infertility support groups; in comparison, little is known about how "lurkers" (i.e., those individuals who read messages but do not post messages) use and benefit from online infertility support groups. The purpose of the present study was to compare the use and experience of online infertility support groups between lurkers and posters. A total of 295 participants who were recruited from several online infertility support groups completed an online questionnaire containing questions about their use and experience of online support groups and measures of loneliness, social support, marital satisfaction, and perceived infertility-related stress. Differences between lurkers and posters were analyzed using Mann-Whitney U and χ or Fisher exact tests. Results revealed that compared with posters, lurkers visited the online support groups less often and scored significantly lower in overall satisfaction with the online support group. However, both lurkers and posters reported gaining a range of unique benefits from access to an online support group. Furthermore, there were no significant differences in loneliness, social support, infertility-related stress, and marital satisfaction between lurkers and posters. These findings suggest that reading messages posted to online support groups may be as beneficial as interacting with the group.

    To compare methods of noninvasive measurement of bone mineral content, 40 healthy early postmenopausal women and 68 postmenopausal women with osteoporosis were studied. The methods included mono- and dual-energy quantitative computed tomography (QCT) and dual-photon absorptiometry (DPA) of the lumbar spine, single-photon absorptiometry (SPA) of the distal third of the radius, and combined cortical thickness (CCT) of the second metacarpal shaft. Lateral thoracolumbar radiographic studies were performed and the spinal fracture index calculated. There was good correlation between QCT and DPA methods in early postmenopausal women and moderate correlation in postmenopausal osteoporotic women. Correlations between spinal measurements (QCT or DPA) and appendicular cortical measurements (SPA or CCT) were moderate in healthy women and poor in osteoporotic women. Measurements resulting from one method were not predictive of measurements obtained by another method for individual patients. The strongest correlation with severity of vertebral fracture was provided by QCT and the weakest by SPA. There was good correlation between single- and dual-energy QCT results. Osteoporotic women and younger healthy women can be distinguished by the measurement of spinal trabecular bone density using QCT, and this method is more sensitive than the measurement of spinal integral bone by DPA or of appendicular cortical bone by SPA or CCT.

    The critical state of a nuclear reactor is an unstable equilibrium. The nuclear reactor can go from critical to subcritical state or can go from critical to hypercritical state. Although the evolution of the system in these cases is slow, it requires the intervention of an operator to correct deviations. For this reason an automatic control technique was designed, based on the kinetic point to a group of delayed neutrons, which corrects deviations automatically. In this paper we study the point kinetics models in a group and six groups of delayed neutrons for different values of reactivity using the simulations software MATLAB, Simulink. A comparison of two models with the reactor kinetic behavior is made (author)

    In this study, we investigated the effects of age and of mild cognitive impairment (MCI) on decision making under risk by adopting a task representing real-life health-related situations and involving complex numerical information. Moreover, we assessed the relationship of real-life decision making to other cognitive functions such as number processing, executive functions, language, memory, and attention. For this reason, we compared the performance of 19 healthy, relatively younger adults with that of 18 healthy older adults and the performance of the 18 healthy older adults with that of 17 patients with MCI. Results indicated difficulties in real-life decision making for the healthy older adults compared with the healthy, relatively younger adults. Difficulties of patients with MCI relative to the healthy older adults arose in particular in difficult items requiring processing of frequencies and fractions. Significant effects of age and of MCI in processing frequencies were also evident in a ratio number comparison task. Decision-making performance of healthy participants and of the patient group correlated significantly with number processing. There was a further significant correlation with executive functions for the healthy participants and with reading comprehension for the patients. Our results suggest that healthy older individuals and patients with MCI make less advantageous decisions when the information is complex and high demands are put on executive functions and numerical abilities. Moreover, we show that executive functions and numerical abilities are not only essential in laboratory gambling tasks but also in more realistic and ecological decision situations within the health context.

    Tree-drawing test is used as a projective psychological test that expresses the abnormal internal experience in patients with schizophrenia (SZ). Despite the widely accepted view that the cognitive function is involved in characteristic tree-drawing in patients with SZ, no study has psychophysiologically examined it. The present study aimed to investigate the involvement of cognitive function during tree-drawing in patients with SZ. For that purpose, we evaluated the brain function in patients with SZ during a tree-drawing task by using near-infrared spectroscopy (NIRS) and compared them with those in healthy controls. The subjects were 28 healthy controls and 28 patients with SZ. Changes in the oxygenated hemoglobin ([oxy-Hb]) concentration in both the groups during the task of drawing a tree imagined freely (free-drawing task) and the task of copying an illustration of a tree (copying task) were measured by using NIRS. Because of the difference between the task conditions, [oxy-Hb] levels in controls during the free-drawing task were higher than that during the copying task at the bilateral frontal pole regions and left inferior frontal region. Because of the difference between the groups, [oxy-Hb] levels at the left middle frontal region, bilateral inferior frontal regions, bilateral inferior parietal regions, and left superior temporal region during the free-drawing task in patients were lower than that in controls. [oxy-Hb] during the tree-drawing task in patients with SZ was lower than that in healthy controls. Our results suggest that brain dysfunction in patients with SZ might be associated with their tree-drawing.

    Previous studies have reported that older cancer patients experience lower psychological distress than younger patients, but most prior studies do not differentiate between age groups within the 'older' category. The aim of this study was to assess the intensity of the symptoms of depression, anxiety, and somatic symptoms among different age groups of older cancer patients. Participants were composed of 321 cancer patients 60 years and older, who were divided into three age groups: 60-69, 70-79, and 80+ years. The participants answered the Brief Symptom Inventory-18, which included subscales for depression, anxiety, and somatic symptoms and the cancer-related problem list, in addition to providing personal and cancer-related details. Depressive, anxiety, and somatic symptoms and cancer-related problems were lowest in the 70-79 years age group and highest in the 80+ years age group. Comparisons between pairs of groups showed significant differences between each of the groups in Brief Symptom Inventory total scores and between the 80+ years age group and the other two groups in regard to depressive symptoms and cancer-related problems. Differences, related to anxiety and somatic symptoms, were significant for the 70-79 year olds, in comparison with the youngest and oldest groups. Intensity of symptoms was explained by older age, higher number of cancer-related problems, female gender, and lower income. Nonlinear relations exist between age and psychological symptoms, which is in line with the postponement of age-related health and functional decline in the modern era. These results suggest that the study of psychological reactions to cancer should examine differences between age groups among older cancer patients. Copyright © 2013 John Wiley & Sons, Ltd.

    The present study investigated people's perception of their own as compared to their peers' healthy eating and related these perceptions to actual healthy eating, BMI, and subsequent healthy eating behavior. Data were collected within the framework of the longitudinal cohort study Konstanz Life Study (T1: N = 770; T2: N = 510). Our results demonstrated an optimistic bias on the group level. Specifically, people rated their own eating behavior as healthier on average than that of their average peers. This comparative optimism occurred even when actual healthy eating was unfavorable and BMI was high. However, it increased with actual healthy eating behavior. Importantly, optimistic perceptions were positively related to the intention to eat healthily and healthy eating six months later. Hence, the results suggest that an optimistic comparative view of one's own healthy eating is grounded in reality and boosts rather than deters subsequent health behavior. This implies that there might not be a need to reduce optimistic perceptions of healthy eating behavior. Copyright © 2015 Elsevier Ltd. All rights reserved.

    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 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.

    The aim of this study was to investigate the immunodulatory properties of dental pulp stem cells derived from healthy (SCD) and inflamed pulp deciduous (SCDIP) tissues. The overall hypothesis is that SCDIP possess equal immune properties with SCD and could be used as an alternative tissue source in regenerative medicine. An intra-oral examination was carried out to assess the status of the pulp tissues and group them according to healthy or inflamed. Primary cells were established from these groups, and basic mesenchymal stem cells (MSC) characterizations were conducted. The expression of human leukocyte antigen (HLA), namely HLA-G, HLA-DR, and HLA-ABC were examined in both cell lines using flow cytometry. We further compared the immunosuppressive effects of SCD and SCDIP on phytohemagglutinin-induced T cell proliferation. Supernatants were tested for cytokine profiling using multiplex array. While SCD exhibited typical MSC characteristics, SCDIP on the other hand, did not. Compared with SCDIP, SCD effectively suppresses mitogen-induced T cells proliferation in a dose-dependent manner, as well as express a higher percentage of HLA-ABC and HLA-G. In addition, levels of several cytokines, such as TNF-α, TNF-β, and IL-2, were drastically suppressed in SCD than SCDIP. Furthermore, a high level of IL-10, an important anti-inflammatory cytokine, was present in SCD compared with SCDIP. These findings suggest that SCDIP is highly dysfunctional in terms of their stemness and immunomodulatory properties. SCDIP is not a viable therapeutic cell source especially when used in graft versus host disease (GvHD) and organ rejection.

    Full Text Available Introduction: In view of the relationship between physical activity and nutrition on body composition, we assessed lean and fat mass and BMC (total and regional in professional Indian sportswomen and compared it with apparently healthy age- and sex-matched females. Materials and Methods: This cross-sectional study included 104 sportswomen and an equal number of age-matched normal healthy females (controls. They were evaluated for anthropometry and body composition (fat, lean mass, and bone mineral content (BMC by DXA. Results: Mean age (19.1 ± 1.3 vs. 19.4 ± 1.5 years and body mass index (21.34 ± 3.02 vs. 21.26 ± 4.05 kg/m 2 were comparable in both groups. Sportswomen had higher intake of energy, macronutrients, calcium, phosphorus and magnesium. Total lean mass (33.67 ± 3.49 vs. 31.14 ± 3.52 kg, P < 0.0001, appendicular skeletal muscle index (5.84 ± 0.57 vs. 5.46 ± 0.63 kg/m 2 ; P < 0.0001 and BMC (2.27 ± 0.32 vs. 2.13 ± 0.34 kg, P < 0.002 was significantly higher and percentage fat mass was significantly lower (33.1 ± 7.5 vs. 37.0 ± 8.3; P < 0.0001 among sportswomen when compared to controls. Conclusions: Indian sportswomen have a higher total and regional lean mass, BMC, and lower percentage fat mass when compared with healthy females. Physical activity, energy, protein and calcium intake were positively associated with lean mass and BMC.

    Some groups have focused on the detection and management of subjective memory impairment (SMI) as the stage that precedes mild cognitive impairment (MCI). However, there have been few clinical studies that have examined biomarkers of SMI to date. To investigate the differences in glucose metabolism as a prodromal marker of dementia in patients with SMI, MCI, and healthy controls using brain F-18 fluoro-2-deoxyglucose positron emission tomography (FDG-PET). Sixty-eight consecutive patients with SMI, 47 patients with MCI, and 42 age-matched healthy subjects were recruited. All subjects underwent FDG-PET and detailed neuropsychological testing. FDG-PET images were analyzed using the statistical parametric mapping (SPM) program. FDG-PET analysis showed glucose hypometabolism in the periventricular regions of patients with SMI and in the parietal, precentral frontal, and periventricular regions of patients with MCI compared with healthy controls. Interestingly, hypometabolism on FDG-PET was noted in the parietal and precentral frontal regions in MCI patients compared to SMI patients. The results suggest that hypometabolism in the periventricular regions as seen on FDG-PET may play a role as a predictive biomarker of pre-dementia, and the extension of reduced glucose metabolism into parietal regions likely reflects progression of cognitive deterioration. © The Foundation Acta Radiologica 2014.

    The purpose of this study was to explore and compare foot and ankle characteristics in people with stroke and healthy controls; and between stroke fallers and non-fallers. Participants were recruited from community groups and completed standardized tests assessing sensation, foot posture, foot function, ankle dorsiflexion and first metatarsal phalangeal joint range of motion (1st MPJ ROM), hallux valgus presence and severity. Twenty-three stroke participants (mean age 75.09 ± 7.57 years; 12 fallers) and 16 controls (mean age 73.44 ± 8.35 years) took part. Within the stroke group, reduced 1st MPJ sensation (p = 0.016) and 1st MPJ ROM (p = 0.025) were observed in the affected foot in comparison to the non-affected foot; no other differences were apparent. Pooled data (for both feet) was used to explore between stroke/control (n = 78 feet) and stroke faller/non-faller (n = 46 feet) group differences. In comparison to the control group, stroke participants exhibited reduced sensation of the 1st MPJ (p = 0.020), higher Foot Posture Index scores (indicating greater foot pronation, p = 0.008) and reduced foot function (p = 0.003). Stroke fallers exhibited significantly greater foot pronation in comparison to non-fallers (p = 0.027). Results indicated differences in foot and ankle characteristics post stroke in comparison to healthy controls. These changes may negatively impact functional ability and the ability to preserve balance. Further research is warranted to explore the influence of foot problems on balance ability and falls in people with stroke. Implications for Rehabilitation Foot problems are common post stroke. As foot problems have been linked to increased fall risk among the general population we recommend that it would be beneficial to include foot and ankle assessments or a referral to a podiatrist for people with stroke who report foot problems. Further research is needed to explore if we can improve functional

    Posturography systems that incorporate force platforms are considered to assess balance and postural control with greater sensitivity and objectivity than conventional clinical tests. The Wii Balance Board (WBB) system has been shown to have similar performance characteristics as other force platforms, but with lower cost and size. To determine the validity and reliability of a freely available WBB-based posturography system that combined the WBB with several traditional balance assessments, and to assess the performance of a cohort of stroke individuals with respect to healthy individuals. Healthy subjects and individuals with stroke were recruited. Both groups were assessed using the WBB-based posturography system. Individuals with stroke were also assessed using a laboratory grade posturography system and a battery of clinical tests to determine the concurrent validity of the system. A group of subjects were assessed twice with the WBB-based system to determine its reliability. A total of 144 healthy individuals and 53 individuals with stroke participated in the study. Concurrent validity with another posturography system was moderate to high. Correlations with clinical scales were consistent with previous research. The reliability of the system was excellent in almost all measures. In addition, the system successfully characterized individuals with stroke with respect to the healthy population. The WBB-based posturography system exhibited excellent psychometric properties and sensitivity for identifying balance performance of individuals with stroke in comparison with healthy subjects, which supports feasibility of the system as a clinical tool.

    Full Text Available Context: Tobacco smoking is considered to be a major risk factor associated with periodontal disease. Smoking exerts a major effect on the protective elements of the immune response, resulting in an increase in the extent and severity of periodontal destruction. Aims: The aim of the present study was to assess viability and phagocytic function of neutrophils in circulating blood of the smokers and nonsmokers who are periodontally healthy. Settings and Design: Two hundred subjects in the mean range of 20–30 years of age were included in the study population. It was a retrospective study carried out for 6 months. Materials and Methods: Two hundred subjects were divided into four groups: 50 nonsmokers, 50 light smokers (15 cigarettes/day. Full mouth plaque index, sulcus bleeding index, and probing depths were measured. Percentage viability of circulating neutrophils and average number of phagocytosed Candida albicans were recorded. Statistical Analysis Used: Means and standard deviations were calculated from data obtained within the groups. Comparison between the smokers and nonsmokers was performed by Kruskal–Wallis ANOVA analysis. Comparison between smoker groups was performed using Mann–Whitney–Wilcoxon test. Results: Percentage viability of neutrophils was significantly less in heavy smokers (66.9 ± 4.0, moderate (76.6 ± 4.2, light smokers (83.1 ± 2.5 as compared to nonsmokers (92.3 ± 2.6 (P < 0.01. The ability of neutrophils to phagocytose, i.e., mean particle number was significantly less in light smokers (3.5 ± 0.5, moderate smokers (2.3 ± 0.5, and heavy smokers (1.4 ± 0.5 compared to nonsmokers (4.9 ± 0.7 (P < 0.01 with evidence of dose-response effect. Conclusions: Smoking significantly affects neutrophils viability and phagocytic function in periodontally healthy population.

    Pain management is an important component of foal nursing care, and no objective data currently exist regarding the analgesic efficacy of opioids in foals. To evaluate the somatic antinociceptive effects of 2 commonly used doses of intravenous (i.v.) butorphanol in healthy foals. Our hypothesis was that thermal nociceptive threshold would increase following i.v. butorphanol in a dose-dependent manner in both neonatal and older pony foals. Seven healthy neonatal pony foals (age 1-2 weeks), and 11 healthy older pony foals (age 4-8 weeks). Five foals were used during both age periods. Treatments, which included saline (0.5 ml), butorphanol (0.05 mg/kg bwt) and butorphanol (0.1 mg/kg bwt), were administered i.v. in a randomised crossover design with at least 2 days between treatments. Response variables included thermal nociceptive threshold, skin temperature and behaviour score. Data within each age period were analysed using a 2-way repeated measures ANOVA, followed by a Holm-Sidak multiple comparison procedure if warranted. There was a significant (P<0.05) increase in thermal threshold, relative to Time 0, following butorphanol (0.1 mg/kg bwt) administration in both age groups. No significant time or treatment effects were apparent for skin temperature. Significant time, but not treatment, effects were evident for behaviour score in both age groups. Butorphanol (0.1 mg/kg bwt, but not 0.05 mg/kg bwt) significantly increased thermal nociceptive threshold in neonatal and older foals without apparent adverse behavioural effects. Butorphanol shows analgesic potential in foals for management of somatic painful conditions. © 2012 EVJ Ltd.

    High adherence to healthy diets has the potential to prevent disease and prolong life span, and healthy dietary pattern scores have each been associated with disease and mortality. We studied two commonly promoted healthy diet scores (modified Mediterranean diet score (mMED) and the Healthy Nordic Food Index (HNFI)) and the combined effect of the two scores in association with all-cause and cause-specific mortality (cancer, CVD and ischaemic heart disease). The study included 38 428 women (median age of 61 years) from the Swedish Mammography Cohort. Diet and covariate data were collected in a questionnaire. mMED and HNFI were generated and categorised into low-, medium- and high-adherence groups, and in nine combinations of these. Multivariable-adjusted hazard ratios (HR) of register-ascertained mortality and 95 % CI were calculated in Cox proportional hazards regression analysis. During follow-up (median: 17 years), 10 478 women died. In the high-adherence categories compared with low-adherence categories, the HR for all-cause mortality was 0·76 (95 % CI 0·70, 0·81) for mMED and 0·89 (95 % CI 0·83, 0·96) for HNFI. Higher adherence to mMED was associated with lower mortality in each stratum of HNFI in the combined analysis. In general, mMED, compared with HNFI, was more strongly associated with a lower cause-specific mortality. In Swedish women, both mMED and HNFI were inversely associated with all-cause and cardiovascular mortality. The combined analysis, however, indicated an advantage to be adherent to the mMED. The present version of HNFI did not associate with mortality independent of mMED score.

    It has been shown that exposure to female thin ideals in media has minimal to moderate direct effects on body image satisfaction (BIS), mood and dysfunctional eating in healthy young women. Evidence has been found for several intervening variables such as social comparison processes. Accordingly it is assumed, that cognitive processing (rather than mere media exposure) is crucial. Consequently, vivid imagination of thin ideals after exposure to a fashion magazine was induced in order to trigger cognitive processes. Changes in mood, BIS and resulting bodyrelated cognitive distortions (Thought-Shape Fusion Body, TSF-B) were assessed. A total of 91 healthy women (mean age 21.9 years, SD = 2.0) were exposed to either a fashion magazine (thin-ideal group) or a nature magazine (control group) in a waiting room design. Afterwards they were instructed to vividly imagine either the thin ideals or landscapes. When exposed to thin ideals, a significant decrease in mood and BIS emerged after vivid imagination, but not after mere magazine exposure. Imagining thin ideals triggered body-related cognitive distortions (TSF-B). A higher degree of eating disorder (ED) symptomatology amplified this effect. These findings apply to young healthy females and cannot be generalized to samples with obesity, EDs or males. Internal validity is limited since the intensity of the exposure has not been systematically controlled. Vivid imagination of thin ideals promoted by magazines results in impaired mood and BIS and moreover in body-related cognitive distortions (TSF-B) in healthy women, especially, for those with stronger ED symptomatology.

    The effect of saline iontophoresis on skin barrier function and irritation was investigated in four ethnic groups (Caucasians, Hispanics, Blacks and Asians). Forty healthy human volunteers were recruited according to specific entry criteria. Ten subjects, five males and five females, were assigned to each ethnic group. Skin barrier function was examined after 4 hours of saline iontophoresis at a current density of 0.2 mA/cm(2) on a 6.5 cm(2) area in terms of the measured responses: transepidermal water loss (TEWL), skin capacitance, skin temperature and visual scores. There were significant differences in TEWL among the ethnic groups prior to patch application. TEWL at baseline in ethnic groups was in the rank order: Caucasian>Asian>Hispanic>Black. Iontophoresis was generally well tolerated, and skin barrier function was not irreversibly affected by iontophoresis in any group. There was no significant skin temperature change, compared to baseline, in any ethnic groups at any observation point. Edema was not observed. At patch removal, the erythema score was elevated in comparison to baseline in all ethnic groups; erythema resolved within 24 hours. Thus, saline iontophoresis produced reversible changes in skin barrier function and irritation in healthy human subjects.

    Full Text Available Background: Cigarette smoke is probably the most significant source of exposure to toxic chemicals for humans, involving health-damaging components, such as nicotine, hydrogen cyanide and formaldehyde. The aim of the present study was to assess the influence of chronic heavy smoking on color discrimination (CD. Methods: All subjects were free of any neuropsychiatric disorder, identifiable ocular disease and had normal acuity. No abnormalities were detected in the fundoscopic examination and in the optical coherence tomography exam. We assessed color vision for healthy heavy smokers (n = 15; age range, 20-45 years, deprived smokers (n = 15, age range 20-45 years and healthy non-smokers (n = 15; age range, 20-45 years, using the psychophysical forced-choice method. All groups were matched for gender and education level. In this test, the volunteers had to choose the pseudoisochromatic stimulus containing a test frequency at four directions (e.g., up, down, right and left in the subtest of Cambridge Colour Test (CCT: Trivector. Results: Performance on CCT differed between groups, and the observed pattern was that smokers had lower discrimination compared to non-smokers. In addition, deprived smokers presented lower discrimination to smokers and non-smokers. Contrary to expectation, the largest differences were observed for medium and long wavelengths. Conclusions: These results suggests that cigarette smoking, chronic exposure to its compounds, and withdrawal from nicotine affect color discrimination. This highlights the importance of understanding the diverse effects of nicotine on attentional bias.

    Objective: To compare T wave alternans in patients with cardiomyopathy and healthy controls. Study Design: Cross-sectional comparative study. Place and Duration of Study: Department of Cardiac Electrophysiology, Armed Forces Institute of Cardiology Rawalpindi, from Feb 2016 to Aug 2016. Material and Methods: Sixty patients with cardiomyopathy (any type) along with sixty healthy controls of matched age and gender were recruited through non-probability purposive sampling. Patients with diabetes mellitus, cerebrovascular accident, heart failure, bundle branch block, systemic arterial hypertension and ongoing antiarrhythmic therapy were excluded from the study. DMS 300-4L Holters were used to obtain ambulatory ECG recordings. Cardio Scan premier 12 lux software was used for analysis of T wave alternans. Results: Total one twenty subjects were enrolled in the study. Cardiomyopathic patients with positive T wave alternans were 13 (21.7 percent) out of 60, while only 4 (6.7 percent) out of 60 healthy controls demonstrated positive T wave alternans. There was significant variation in frequency of patients with positive T wave alternans as compared to healthy controls with p-value of 0.02. In cases the mean value of T wave alternans was 55.10 µv ± 33.58 while 39.45 µv ± 13.53 in controls. The difference in mean value of T wave alternans between cases and controls was significant with p-value of 0.001. Conclusion: The frequency of patients with cardiomyopathy having positive T wave alternans was significantly higher as compared to the healthy controls. (author)

    In 2005, the diagnostic criteria for Japan-specific metabolic syndrome were published. The representative health habits are Breslow's seven healthy practices, Morimoto's eight items and Ikeda's six healthy habits. We investigated the prevalence of metabolic syndrome related with life-style strongly among these three sets of healthy habit. Cross-sectional study was conducted for the prevalence of metabolic syndrome by practicing these healthy habits. 20,776 Japanese individuals visited the Health Science Center at Jikei University Hospital in Japan for medical check-ups. Subjects were divided into 8 groups based on gender and age (females in their 30s, 40s, 50s and 60s, and males in their 30s, 40s, 50s and 60s). Participants completed a simple, self-administered lifestyle questionnaire based on the three sets of healthy habits. Subjects were divided into three groups (poor, moderate and favorable) according to each of the healthy habit criteria. Significant differences were observed among 10 groups for Breslow's seven healthy practices, 4 groups for Morimoto's eight items, and 13 groups for Ikeda's six healthy habits. Ikeda's six healthy habits showed the most significant differences among the three sets of habits. Among the three methods tested, to practice more Ikeda's healthy habits were the most useful for metabolic syndrome. © 2009 Asian Oceanian Association for the Study of Obesity .

    The present research investigated the effects of two different types of music on cardiovascular responses in essential hypertensive men in comparison with healthy men based on introversion and extraversion. One hundred and thirteen hypertensive men referred to Madani Heart Hospital in Tabriz completed the NEO-FFI Questionnaire and after obtaining acceptable scores were classified in four groups: introvert patients, extravert patients, introvert healthy subjects, and extravert healthy subjects (each group with 25 samples with age range 31-50). Baseline blood pressure and heart rate of each subject was recorded without any stimulus. Then subjects were exposed to slow-beat music and blood pressure and heart rate were recorded. After15 minute break, and a little cognitive task for distraction, subjects were exposed to fast-beat music and blood pressure and heart rate were recorded again. Multivariate analysis of covariance (MANCOVA) test showed that extravert patient subjects obtained greater reduction in systolic blood pressure and heart rate after presenting slow-beat music compared with introvert patients (P= 0.035, and P= 0.033 respectively). And extravert healthy subjects obtained greater reduction in heart rate after presenting slow-beat music compared with introvert healthy subjects (P= 0.036). However, there are no significant differences between introvert and extravert groups in systolic and diastolic blood pressure and heart rate after presenting fast-beat music. Based on our results, introvert subjects experience negative emotions more than extravert subjects and negative emotions cause less change in blood pressure in these subjects compared with extravert subjects.

    Full Text Available The natural surface water, especially available through rivers, is the main source of healthy water for the living beings throughout the world from ancient days as it consists of all essential minerals. With the advent of industrialization, gradually even the most prominent rivers have been polluted in all parts of the world. Although there are lots of technologies, nanofiltration (NF has been chosen to transform river water into healthy water due to its unique advantages of retaining optimum TDS (with essential minerals required for human body, consuming of lower energy, and no usage of any chemicals. The prominent parameters of surface water and macro/microminerals of treated water have been analyzed. It is shown that NF is better in producing healthy water with high flux by consuming low energy.

    Group A Streptococcus (GAS; Streptococcus pyogenes) causes a range of mild to severe infections in humans. It can also colonize healthy persons asymptomatically. Therefore, it is important to study GAS carriage in healthy populations, as carriage of it might lead to subsequent disease manifestation, clonal spread in the community, and/or diversification of the organism. Throat swab culture is the gold standard method for GAS detection. Advanced culture-independent methods provide rapid and efficient detection of microorganisms directly from clinical samples. We investigated the presence of GAS in throat swab samples from healthy adults in Japan using culture-dependent and culture-independent methods. Two throat swab samples were collected from 148 healthy volunteers. One was cultured on selective medium, while total DNA extracted from the other was polymerase chain reaction (PCR) amplified with two GAS-specific primer pairs: one was a newly designed 16S rRNA-specific primer pair, the other a previously described V-Na + -ATPase primer pair. Although only 5 (3.4 %) of the 148 samples were GAS-positive by the culture-dependent method, 146 (98.6 %) were positive for the presence of GAS DNA by the culture-independent method. To obtain serotype information by emm typing, we performed nested PCR using newly designed emm primers. We detected the four different emm types in 25 (16.9 %) samples, and these differed from the common emm types associated with GAS associated diseases in Japan. The different emm types detected in the healthy volunteers indicate that the presence of unique emm types might be associated with GAS carriage. Our results suggest that culture-independent methods should be considered for profiling GAS in the healthy hosts, with a view to obtaining better understanding of these organisms. The GAS-specific primers (16S rRNA and V-Na + -ATPase) used in this study can be used to estimate the maximum potential GAS carriage in people.

    Previous studies have shown that there is a relationship between periodontal disease and the distribution of collagen fibers. This study evaluated the distribution of collagen types I and III in regenerated bone and periodontal ligament, comparing them to the tissues near the regenerated area and to the healthy periodontium. In the third (P3) and fourth (P4) mandibular premolars of 5 healthy mongrel dogs, bilaterally, buccal class 2 furcation lesions were surgically created and chronified for 3 weeks. After that, full flaps were elevated and expanded polytetrafluoroethylene (e-PTFE) membranes were adapted, sutured and recovered by the flaps. Two weeks after surgery, two membranes on the same side were removed and the other membranes were removed four weeks after surgery. The dogs were euthanized at 12 weeks following placement of the e-PTFE membranes. P3 and P4 teeth as well as the second premolars (healthy control teeth) and their periodontal tissues were removed and histologically processed for Collagen Quantification (COLQ). The amount of type III collagen was higher in native bone compared to the regenerated area. For periodontal ligament, COLQ for type I collagen showed statistically significant differences (Tukeys's Multiple Comparison, p⟨0.05) between the regenerated groups and the control group. These differences were not found for type III COLQ. There are significant differences in collagen distribution among the regenerated, native and control tissues. Membrane removal 2 or 4 weeks postoperatively did not influence the collagen composition.

    Immigrants and refugees to the United States exhibit lower dietary quality than the general population, but reasons for this disparity are poorly understood. In this study, we describe the meanings of food, health and wellbeing through the reported dietary preferences, beliefs, and practices of adults and adolescents from four immigrant and refugee communities in the Midwestern United States. Using a community based participatory research approach, we conducted a qualitative research study with 16 audio-recorded focus groups with adults and adolescents who self-identified as Mexican, Somali, Cambodian, and Sudanese. Focus group topics were eating patterns, perceptions of healthy eating in the country of origin and in the U.S., how food decisions are made and who in the family is involved in food preparation and decisions, barriers and facilitators to healthy eating, and gender and generational differences in eating practices. A team of investigators and community research partners analyzed all transcripts in full before reducing data to codes through consensus. Broader themes were created to encompass multiple codes. Results show that participants have similar perspectives about the barriers (personal, environmental, structural) and benefits of healthy eating (e.g., 'junk food is bad'). We identified four themes consistent across all four communities: Ways of Knowing about Healthy Eating ('Meanings;' 'Motivations;' 'Knowledge Sources'), Eating Practices ('Family Practices;' 'Americanized Eating Practices' 'Eating What's Easy'), Barriers ('Taste and Cravings;' 'Easy Access to Junk Food;' 'Role of Family;' Cultural Foods and Traditions;' 'Time;' 'Finances'), and Preferences for Intervention ('Family Counseling;' Community Education;' and 'Healthier Traditional Meals.'). Some generational (adult vs. adolescents) and gender differences were observed. Our study demonstrates how personal, structural, and societal/cultural factors influence meanings of food and dietary

Forty-two boys with DMD (mean age, 9.9 years) and 31 healthy boys (mean age, 11.4 years) were included in the study. Age, body mass index, and clinical function scale grade were evaluated. T1-weighted MR images and T2 maps with and without fat suppression were obtained. Fatty infiltration was graded 0-4 on T1-weighted images, and derived T2 fat values (difference between mean T2 values from T2 maps with and without fat suppression) of the gluteus maximus and vastus lateralis muscles were calculated. Group comparisons were performed. The upper limit of the 95% reference interval of T2 fat values from the control group was applied. There was no significant difference in age or body mass index between groups. All healthy boys and 19 boys (45.2%) with DMD had a normal clinical function scale grade. Grade 1 fatty infiltration was seen in 90.3% (gluteus maximus) and 71.0% (vastus lateralis) of healthy boys versus 33.3% (gluteus maximus) and 52.4% (vastus lateralis) of boys with DMD. T2 fat values of boys with DMD were significantly longer than in the control group (p < 0.001). Using a 95% reference interval for healthy boys for the gluteus maximus (28.3 milliseconds) allowed complete separation from boys with DMD (100% sensitivity, 100% specificity), whereas the values for the vastus lateralis (7.28 milliseconds) resulted in 83.3% sensitivity and 100% specificity. Measurement of muscular fat with T2 maps is accurate for differentiating boys with DMD from healthy boys.

    The present study investigated factors that protect people low in trait self-esteem (Low-SEs), who may be less skilled at constructing information in self-enhancing manners, from threats after interpersonal upward comparison with in-group members. We hypothesized that even Low-SEs can maintain their state self-esteem under intergroup upward comparison. Furthermore, this study explored the possibility that individuals used identity-shift, a strategy to maintain their personal identity, even in...

    ". This paper highlights the role that the organisation of food provision plays by comparing the attitudes of students towards in-school food provision as opposed to out-of-school provision where food is provided by outside caterers. Schools having internal food production and schools having external food...... operated catering seems to have a negative effect on the social and cultural structures and functions related to the meal during lunchtime. Having meals in schools where external caterers are employed is experienced as an individual act by the students in comparison with schools having internal catering......Unhealthy eating are common among adolescents and the school is a well suited setting for promoting healthy eating. For the school to play a role here, however an environment must be created, in which the school and the students develop a sense of ownership for a healthy food and nutrition "regime...

    Adolescents with childhood-onset chronic condition (COCC) are at increased risk for physical and psychological problems. Despite being at greater risk and having to deal with traumatic experiences and uncertainty, most adolescents with COCC do well across many domains. The Positive Youth Development (PYD) perspective provides a framework for examining thriving in youth and has been useful in understanding positive outcomes for general populations of youth as well as at-risk youth. This study aimed to compare levels of PYD assets between youth with COCC and youth without illness. Participants with COCC were recruited from specialty pediatric clinics while healthy participants were recruited from a large pediatric primary care practice. Inclusion criteria for participants included being (1) English speaking, (2) no documented intellectual disability in electronic medical record, and (3) aged between 13 and 18 years during the recruitment period. Univariate and bivariate analyses on key variables were conducted for adolescents with and without COCC. Finally, we performed multivariable linear regressions for PYD and its subdomains. There were no significant differences between overall PYD or any of the subdomains between the two groups. Multivariable linear regression models showed no statistically significant relationship between chronic condition status and PYD or the subdomains. The findings from this study support the application of the PYD perspective to this population of youth. The results of this study suggest that approaches shown to benefit healthy youth, could be used to promote positive outcomes for youth with COCC.

    Objectives. We examined availability and food options at restaurants in less affluent (target area) and more affluent (comparison area) areas of Los Angeles County to compare residents’ access to healthy meals prepared and purchased away from home. We also considered environmental prompts that encourage the purchase of various foods. Methods. We designed an instrument to assess the availability, quality, and preparation of food in restaurants. We also assessed advertisements and promotions, cleanliness, and service for each restaurant. We assessed 659 restaurants: 348 in the target area and 311 in the comparison area. Results. The nutritional resource environment in our target area makes it challenging for residents to eat healthy away from home. Poorer neighborhoods with a higher proportion of African American residents have fewer healthy options available, both in food selections and in food preparation; restaurants in these neighborhoods heavily promote unhealthy food options to residents. Conclusions. Environment is important in understanding health status: support for the healthy lifestyle associated with lower risks for disease is difficult in poorer communities with a higher proportion of African American residents.

    To evaluate the impact of a family-oriented inpatient rehabilitation programme on behavioural and emotional problems in healthy siblings of chronically ill children and to assess the association between these problems and quality of life. A total of 259 healthy children (4-16 years, M = 8.6 years, SD = 3.3) with a chronically ill sibling were enrolled in the study. Parents filled in the Strengths and Difficulties Questionnaire, while the children answered a self-report quality of life instrument (LQ-KID) at the time of admission and discharge from the clinic and at a 6-month follow-up. Comparisons were performed with a matched control group from the German general population (n= 777). Significant behavioural or emotional symptoms were found in 30.5% of the healthy siblings, the relative risk of having elevated scores being 2.2 compared with the control group. Symptoms were inversely correlated with quality of life (r=-0.42). During the inpatient rehabilitation, symptoms decreased significantly to a normal level. Similarly, quality of life significantly improved, except in the dimension family relations. Family-oriented inpatient rehabilitation is a promising approach to improve the mental health of children with a chronically ill sibling.

    Full Text Available Background: Soymilk fermented by lactobacilli and/or bifidobacteria is attracting attention due to the excellent bioavailability of its isoflavones. We investigated the effects of fermented soymilk containing high amounts of isoflavone aglycones on facial wrinkles and urinary isoflavones in postmenopausal women in a randomized, parallel-group, open-label trial. Healthy Japanese women were randomly divided into active (n = 44, mean age 56.3 ± 0.5 or control (n = 44, mean age 56.1 ± 0.5 groups, who consumed or did not consume a bottle of soymilk fermented by Bifidobacterium breve strain Yakult and Lactobacillus mali for 8 weeks. Maximum depth of wrinkles around the crow’s feet area and other wrinkle parameters were evaluated as primary and secondary endpoints respectively at weeks 0, 4, and 8 during the consumption period. Urinary isoflavone levels were determined by liquid chromatography-mass spectrometry. Results: The active group demonstrated significant improvements in the maximum depth (p=0.015 and average depth (p=0.04 of wrinkles, and significantly elevated urinary isoflavones (daidzein, genistein, and glycitein; each p < 0.001 compared with the control during the consumption period. No serious adverse effects were recorded. Conclusion: These findings suggest that fermented soymilk taken daily may improve facial wrinkles and elevate urinary isoflavones in healthy postmenopausal women.

    Full Text Available Current research on perceptual organization in schizophrenia frequently employs shapes with regularly sampled contours (fragmented stimuli, in noise fields composed of similar elements, to elicit visual abnormalities. However, perceptual organization is multi-factorial and, in earlier studies, continuous contours have also been employed in tasks assessing the ability to extract shapes from a background. We conducted a systematic review and meta-analysis of studies using closed-contour stimuli, including the Embedded Figures Test (EFT and related tasks, both in people with schizophrenia and in healthy schizotypes and relatives, considered at increased risk for psychosis. Eleven studies met the selection criteria for inclusion in the meta-analysis, including six that used a between-groups study design (i.e. perceptual organization abilities of schizophrenia/high-risk groups were compared to healthy or clinical controls, and five that treated schizophrenia symptoms or schizotypy traits and indices of perceptual organization as continuous variables. Effect sizes and heterogeneity statistics were calculated, and the risk of publication bias was explored. A significant, moderate effect for EFT performance was found with studies that compared performance of schizophrenia/high-risk groups to a healthy or patient comparison group (d = -.523, p<.001. However, significant heterogeneity was also found amongst the schizotypy, but not schizophrenia studies, as well as studies using accuracy, but not reaction time as a measure of performance. A non-significant correlation was found for the studies that examined schizophrenia symptoms or schizotypy traits as continuous variables (r = .012, p = .825. These results suggest that deficits in perceptual organization of non-fragmented stimuli are found when differences between schizophrenia/high-risk groups and comparison groups are maximized. These findings should motivate further investigation of perceptual

    Evidence increasingly indicates that childhood obesity prevention efforts should begin as early as infancy. However, few interventions meet the needs of families whose infants are at increased obesity risk due to factors including income and maternal body mass index (BMI). Social media peer groups may offer a promising new way to provide these families with the knowledge, strategies, and support they need to adopt obesity prevention behaviors. The aim of this study is to develop and pilot test a Facebook-based peer group intervention for mothers, designed to prevent pediatric obesity and promote health beginning in infancy. We conducted in-depth semi-structured interviews with 29 mothers of infants and focus groups with 30 pediatric clinicians, to inform the development of a theory-based intervention. We then conducted a single-group pilot trial with 8 mothers to assess its feasibility and acceptability. All participants were recruited offline at pediatric primary care practices. Participants in the pilot trial joined a private Facebook group, moderated by a psychologist, with a weekly video-based curriculum, and also had the option to meet at a face-to-face event. Within the Facebook group, mothers were encouraged to chat, ask questions, and share photos and videos of themselves and babies practicing healthy behaviors. Consistent with the literature on obesity prevention, the curriculum addressed infant feeding, sleep, activity, and maternal well-being. Feasibility was assessed using the frequency and content of group participation by mothers, and acceptability was measured using online surveys and phone interviews. Based on preferences of mothers interviewed (mean BMI 35 kg/m(2), all Medicaid-insured, mean age 27, all Black), we designed the intervention to include frequent posts with new information, videos showing parents of infants demonstrating healthy behaviors, and an optional face-to-face meeting. We developed a privacy and safety plan that met the needs

    The faecal flora is a common reservoir for urinary tract infection (UTI), and Escherichia coli (E. coli) is frequently found in this reservoir without causing extraintestinal infection. We investigated these E. coli reservoirs by whole-genome sequencing a large collection of E. coli from healthy controls (faecal), who had never previously had UTI, and from UTI patients (faecal and urinary) sampled from the same geographical area. We compared MLST types, phylogenetic relationship, accessory genome content and FimH type between patient and control faecal isolates as well as between UTI and faecal-only isolates, respectively. Comparison of the accessory genome of UTI isolates to faecal isolates revealed 35 gene families which were significantly more prevalent in the UTI isolates compared to the faecal isolates, although none of these were unique to one of the two groups. Of these 35, 22 belonged to a genomic island and three putatively belonged to a type VI secretion system (T6SS). MLST types and SNP phylogeny indicated no clustering of the UTI or faecal E. coli from patients distinct from the control faecal isolates, although there was an overrepresentation of UTI isolates belonging to clonal lineages CC73 and CC12. One combination of mutations in FimH, N70S/S78N, was significantly associated to UTI, while phylogenetic analysis of FimH and fimH identified no signs of distinct adaptation of UTI isolates compared to faecal-only isolates not causing UTI. In summary, the results showed that (i) healthy women who had never previously had UTI carried faecal E. coli which were overall closely related to UTI and faecal isolates from UTI patients; (ii) UTI isolates do not cluster separately from faecal-only isolates based on SNP analysis; and (iii) 22 gene families of a genomic island, putative T6SS proteins as well as specific metabolism and virulence associated proteins were significantly more common in UTI isolates compared to faecal-only isolates and (iv) evolution of fim

    Children and adolescents with psychogenic non-epileptic seizures (PNES) and epilepsy are known to have psychosocial problems. The aim of the present study was to compare the psychosocial difficulties, history of stressful life events/abuse, psychiatric diagnosis, and self-esteem of adolescents with PNES to the ones with epilepsy and healthy controls at a tertiary care center in Turkey. Thirty-four adolescents with PNES diagnosed by video-EEG were compared with 23 adolescents that have epilepsy and 35 healthy volunteers. Comorbid psychiatric diagnoses of participants were examined by semi-structured interviews using Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (KSADS-PL). Self-esteem of adolescents was evaluated by Rosenberg Self Esteem Scale (RSES). No differences in sociodemographic features were observed between the groups. The PNES group showed significantly higher rates of parental conflicts, difficulties in relationship with siblings/peers, school under-achievement, and history of stressful events/abuse. The rates of comorbid psychiatric disorders were 64.7% in PNES and 47.8% in epilepsy group. The most common disorders in both groups were attention deficit hyperactivity disorder (ADHD) and depressive disorder. The rate of posttraumatic stress disorder (PTSD) was significantly increased in the PNES group. Additionally, adolescents with PNES displayed significantly lower levels of self-esteem than the other groups. It could be concluded that both disorders involved a high risk for developing psychiatric disorders; additionally, adolescents with PNES have higher rates of stressors and lower levels of self-esteem. Findings from this investigation point to the importance of psychiatric interventions in pediatric PNES and also epilepsy.

    The purpose of the study was to optimize the sample preparation and to further use an improved sample preparation to identify proteome differences between inflamed ulcerative colitis tissue from untreated adults and healthy controls. To optimize the sample preparation, we studied the effect of adding different detergents to a urea containing lysis buffer for a Lys-C/trypsin tandem digestion. With the optimized method, we prepared clinical samples from six ulcerative colitis patients and six healthy controls and analysed them by LC-MS/MS. We examined the acquired data to identify differences between the states. We improved the protein extraction and protein identification number by utilizing a urea and sodium deoxycholate containing buffer. Comparing ulcerative colitis and healthy tissue, we found 168 of 2366 identified proteins differently abundant. Inflammatory proteins are higher abundant in ulcerative colitis, proteins related to anion-transport and mucus production are lower abundant. A high proportion of S100 proteins is differently abundant, notably with both up-regulated and down-regulated proteins. The optimized sample preparation method will improve future proteomic studies on colon mucosa. The observed protein abundance changes and their enrichment in various groups improve our understanding of ulcerative colitis on protein level. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Extensive attention has been focused on improving the dietary intake of Americans. Such focus is warranted due to increasing rates of overweight, obesity, and other dietary-related disease. To address suboptimal dietary intake requires an improved, contextualized understanding of the multiple and intersecting influences on healthy eating, particularly among those populations at greatest risk of and from poor diet, including rural residents. During 8 focus groups (N = 99) and 6 group key informant interviews (N = 20), diverse Appalachian rural residents were queried about their perceptions of healthy eating, determinants of healthy food intake, and recommendations for improving the dietary intake of people in their communities. Participants included church members and other laypeople, public health officials, social service providers, health care professionals, and others. Participants offered insights on healthy eating consistent with the categories of individual, interpersonal, community, physical, environmental, and society-level influences described in the socioecological model. Although many participants identified gaps in dietary knowledge as a persistent problem, informants also identified extraindividual factors, including the influence of family, fellow church members, and schools, policy, advertising and media, and general societal trends, as challenges to healthy dietary intake. We highlight Appalachian residents' recommendations for promoting healthier diets, including support groups, educational workshops, cooking classes, and community gardening. We discuss the implications of these findings for programmatic development in the Appalachian context. © 2013 National Rural Health Association.

    It is commonly assumed that early emotional signals provide relevant information for social cognition tasks. The goal of this study was to test the association between (a) cortical markers of face emotional processing and (b) social-cognitive measures, and also to build a model which can predict this association (a and b) in healthy volunteers as well as in different groups of psychiatric patients. Thus, we investigated the early cortical processing of emotional stimuli (N170, using a face and word valence task) and their relationship with the social-cognitive profiles (SCPs, indexed by measures of theory of mind, fluid intelligence, speed processing and executive functions). Group comparisons and individual differences were assessed among schizophrenia (SCZ) patients and their relatives, individuals with attention deficit hyperactivity disorder (ADHD), individuals with euthymic bipolar disorder (BD) and healthy participants (educational level, handedness, age and gender matched). Our results provide evidence of emotional N170 impairments in the affected groups (SCZ and relatives, ADHD and BD) as well as subtle group differences. Importantly, cortical processing of emotional stimuli predicted the SCP, as evidenced by a structural equation model analysis. This is the first study to report an association model of brain markers of emotional processing and SCP. PMID:23685775

    Recovery high schools (RHS) vary in organization and operating philosophy, but are designed to support the unique needs of students struggling with substance use disorders (SUD). Previous research on youth risk taking behaviors suggests emotion regulation is a key predictor of outcomes. Specifically, the ability to respond in adaptive rather than maladaptive ways is often associated with challenges of impulsivity, poor distress tolerance, and adolescent substance use. The current study considers data from RHS students in order to answer research questions concerning impulsivity and emotion regulation of youth working to change their risk trajectories in comparison to group of typically developing youth. Participants (n = 114) in the study were composed of students enrolled in 3 RHS programs and a comparison group of similar aged youth (15-20 years) without an identified SUD. Data collection occurred through an anonymous online survey set of four measures of reactivity and impulsivity, emotion regulation, and parent and peer influence, as well as an online version of the Stroop Inhibitory Control Task. Participants in the three RHS groups reported decreased emotion regulation abilities, increased impulsivity and increased peer influence when compared to the comparison group; differential effects within RHS are presented. Conclusions/Importance: Results are consistent with the extant literature that difficulty regulating emotions is associated with an increased risk for substance abuse and suggests these difficulties persist in early recovery. Results also suggest the need to better understand how different operating philosophies of programs influence student outcomes and the recovery process.

    Achieving a symmetrical power performance (difference power between the dominant and nondominant legs in healthy young adults, (2) evaluate the effect of a single-leg-dominant sport activity performed at the professional level, and (3) propose a parameter of normality for maximal power difference in the lower limbs of this young adult population. Controlled laboratory study. A total of 78 healthy, male, young adults were divided into 2 groups according to sport activity level. Group 1 consisted of 51 nonathletes (mean ± SD age, 20.8 ± 1.5 years; weight, 71.9 ± 10.5 kg) who participated in less than 8 hours a week of recreational physical activity with nonspecific training; group 2 consisted of 27 single-leg-dominant professional soccer players (age, 18.4 ± 0.6 years; weight, 70.1 ± 7.5 kg) who specifically trained and competed at their particular activity 8 hours or more a week. For assessment of maximal leg power, both groups completed the single-leg squat jump test. Dominance was determined when participants completed 2 of 3 specific tests with the same extremity. Statistical analysis included the Student t test. No statistical difference was found for maximal power between dominant and nondominant legs for nonathletes ( t = -1.01, P = .316) or single-leg-dominant professional soccer players ( t = -1.10, P = .281). A majority (95%) of participants studied showed a power difference of less than 15% between their lower extremities. Among young healthy adults, symmetrical power performance is expected between lower extremities independent of the existence of dominance and difference in sport activity level. A less than 15% difference in power seems to be a proper parameter to define symmetrical power performance assessed by vertical single-leg jump tests.

    Full Text Available The purpose of this study was to observe left ventricular function during acute high-altitude exposure in a large group of healthy young males.A prospective trial was conducted in Szechwan and Tibet from June to August, 2012. By Doppler echocardiography, left ventricular function was examined in 139 healthy young Chinese men at sea level; within 24 hours after arrival in Lhasa, Tibet, at 3700 m; and on day 7 following an ascent to Yangbajing at 4400 m after 7 days of acclimatization at 3700 m. The resting oxygen saturation (SaO2, heart rate (HR and blood pressure (BP were also measured at the above mentioned three time points.Within 24 hours of arrival at 3700 m, the HR, ejection fraction (EF, fractional shortening (FS, stroke volume (SV, cardiac output (CO, and left ventricular (LV Tei index were significantly increased, but the LV end-systolic dimension (ESD, end-systolic volume (ESV, SaO2, E/A ratio, and ejection time (ET were significantly decreased compared to the baseline levels in all subjects. On day 7 at 4400 m, the SV and CO were significantly decreased; the EF and FS Tei were not decreased compared with the values at 3700 m; the HR was further elevated; and the SaO2, ESV, ESD, and ET were further reduced. Additionally, the E/A ratio was significantly increased on day 7 but was still lower than it was at low altitude.Upon acute high-altitude exposure, left ventricular systolic function was elevated with increased stroke volume, but diastolic function was decreased in healthy young males. With higher altitude exposure and prolonged acclimatization, the left ventricular systolic function was preserved with reduced stroke volume and improved diastolic function.

    Full Text Available Abstract Background The incidence and diversity of human methanogens are insufficiently characterised in the gastrointestinal tract of both health and disease. A PCR and clone library methodology targeting the mcrA gene was adopted to facilitate the two-fold aim of surveying the relative incidence of methanogens in health and disease groups and also to provide an overview of methanogen diversity in the human gastrointestinal tract. Results DNA faecal extracts (207 in total from a group of healthy controls and five gastrointestinal disease groups were investigated. Colorectal cancer, polypectomised, irritable bowel syndrome and the control group had largely equivalent numbers of individuals positive for methanogens (range 45–50%. Methanogen incidence in the inflammatory bowel disease groups was reduced, 24% for ulcerative colitis and 30% for Crohn's disease. Four unique mcrA gene restriction fragment length polymorphism profiles were identified and bioinformatic analyses revealed that the majority of all sequences (94% retrieved from libraries were 100% identical to Methanobrevibacter smithii mcrA gene. In addition, mcrA gene sequences most closely related to Methanobrevibacter oralis and members of the order Methanosarcinales were also recovered. Conclusion The mcrA gene serves as a useful biomarker for methanogen detection in the human gut and the varying trends of methanogen incidence in the human gut could serve as important indicators of intestinal function. Although Methanobrevibacter smithii is the dominant methanogen in both the distal colon of individuals in health and disease, the diversity of methanogens is greater than previously reported. In conclusion, the low incidence of methanogens in Inflammatory Bowel Disease, the functionality of the methanogens and impact of methane production in addition to competitive interactions between methanogens and other microbial groups in the human gastrointestinal tract warrants further

    Full Text Available ABSTRACT: Introduction & Objective: The positive and negative effects of perfectionism on human cognition, affection and behavior have been emphasized. Perfectionism has been conceptualized as a multidimensional construct, with both adaptive and maladaptive aspects, which is one of the common personality traits that cause lifelong stress in human and results in anxiety, depression and physical and mental distress.The aim of this study was to assess the positive and negative perfectionism in migrainus patients in comparison with control group. Materials & Methods: This is an analytical (Case-control study which was performed on 91 migraine patients and 88 healthy individuals. The pqtients and controls completed a standard 40 item questionnaire for perfectionism – PANPS (20 for positive and 20 for negative perfectionism . The patients in both groups were matched for gender and age. Mean of positive and negative perfectionism scores for two groups was statistically analysed using SPSS software. Results: Mean positive perfectionism score was 83.47±8.5 for migraine group and 65.47±7.54 for control group (p=0.0001. The difference between two groups was significant. Mean of negative perfectionism score was 74.12±10.6 for migraine group and 51.79±7.8 for control group(p=0.0001. Conclusion: The results show that migraine patients have higher mean of perfectionism scores than healthy individuals. Based on this study and other clinical experiences more attention to psychotherapy is necessary for better management of migraine and recognition of personality profile in migraine patient helps to reduce patient’s complaints.

    The authors examined the components and modifiers of the healthy worker effect using mortality data from three occupational cohorts: the employees of Atomic Energy of Canada Limited followed between 1950 and 1981, a 10% sample of the Canadian labor force followed between 1965 and 1979, and workers at the Eldorado Resources Limited Beaverlodge uranium mine followed between 1950 and 1980. Two important components of the healthy worker effect have been identified in these cohorts, namely, initial selection of and continuing employment of healthy individuals. There is less evidence for a contribution from the existence of differential risk factors among employed individuals as compared with the general population. The healthy worker effect is, however, substantially modified by time since employment, sex, age, specific cause of death, and specific occupation. Because of this variation, it is inappropriate to account for the healthy worker effect by a single parameter, and all of the above factors must be taken into account in any appropriate analysis. When the only available comparison group for an occupational cohort is the general population, the healthy worker effect is unlikely to have any substantial influence on the process of assessing causality for any observed association or attributing cause in an individual case. This would be particularly true for cancer, and even more so for lung cancer, a disease often associated with industrial compensation cases

    Full Text Available Introduction: The nasosinusal microbiology of healthy individuals is not much documented. Its knowledge allows to determine the nasosinusal colonizing agents and to monitor the patterns of bacterial resistance. Objective: To evaluate the microbiology of the middle meatus in healthy individuals and to compare it with that of patients with chronic rhinosinusitis. Method: 61 healthy individuals were included. The samples were collected under endoscopic view and Gram stained with leucocytes count and aerobic, anaerobic and fungus cultures. 114 patients with chronic rhinosinusitis formed the control group. Results: In healthy individuals 58 microorganisms were isolated. The most frequent ones were coagulase-negative Staphylococcus, Staphylococcus and Corynebacterium. Fungi were cultivated in 10%. There were rare or no white blood cells in all samples. There was penicillin resistance in 75% of the Staphylococcus aureus and 69% of the coagulase-negative Staphylococcus. As for oxacillin, 100% of Staphylococcus aureus and 92% of coagulase-negative Staphylococcus were sensitive. In the control group 158 microorganisms were cultivated. The most common ones were Staphylococcus aureus and coagulase-negative Staphylococcus. Gram-negatives represented 26% of the aerobics. 73% of the samples with positive cultures presented a few or many white blood cells. Conclusion: Rare or no white blood cell, coagulase-negative Staphylococcus and Corynebacterium were more frequent in healthy individuals and Streptococcus pneumoniae, anaerobics and oxacillin resistant coagulase-negative Staphylococcus and Gram-negative were more frequent in the control group.

    To compare sexual function and hormone profile in male patients with gynecomastia with matched controls. Forty-seven male subjects with gynecomastia and thirty healthy controls were enrolled in this study. Serum free T3, free T4, TSH, FSH, prolactin, estradiol, total testosterone, free testosterone, DHEA-SO4, LH and total PSA were measured in the patients and controls. Sexual function of the patients and controls were evaluated using International Index of Erectile Function (IIEF). The hormone values and IIEF scores of the patients were statistically compared with the controls'. The mean of age, body mass index, right and left testicular volume in the patient and control group were similar. The mean FSH and free T3 values of the patients were significantly lower than the controls (p = 0.007 and p = 0.03, respectively). The mean of the other hormone values in the both groups were found to be statistically similar (p > 0.05). The mean ±SD of total IIEF scores in the patient and control group were 60.14 ± 8.78 and 65.24 ± 5.52, respectively (p = 0.007). Although the mean IIEF-erectile function, orgasmic function and intercourse satisfaction scores in the patient group were significantly lower than the control group (p gynecomastia were similar with the controls. However, gynecomastia adversely affected male sexual function.

    Full Text Available Background: Age-related cognitive decline is often associated with unsafe driving behavior. We hypothesized that 10 active training sessions in a driving simulator increase cognitive and on-road driving performance. In addition, driving simulator training should outperform cognitive training.Methods: Ninety-one healthy active drivers (62 – 87 years were randomly assigned to either (1 a driving simulator training group, (2 an attention training group (vigilance and selective attention, or (3 a control group. The main outcome variables were on-road driving and cognitive performance. Seventy-seven participants (85% completed the training and were included in the analyses. Training gains were analyzed using a multiple regression analysis with planned comparisons.Results: The driving simulator training group showed an improvement in on-road driving performance compared to the attention training group. In addition, both training groups increased cognitive performance compared to the control group. Conclusion: Driving simulator training offers the potential to enhance driving skills in older drivers. Compared to the attention training, the simulator training seems to be a more powerful program for increasing older drivers’ safety on the road.

    Objectives: To evaluate the efficacy of pomegranate juice supplementation on matrix metalloproteinases 2 and 9 serum levels and improving antioxidant function in young healthy males during exhaustive exercise. Methods: The study was conducted at Ardabil University of Medical Sciences, Iran, in 2010-11 and comprised 28 healthy subjects in 18-24 age bracket. They were randomly divided into control and supplemented groups. One cup of pomegranate juice and one cup of tap water were given to supplemented and control groups daily for two weeks respectively. Fasting blood samples were taken at baseline and at the end of two weeks of intervention. The subjects were given one exhaustive exercise and then fasting blood samples were taken for testing blood glutathione peroxidase and superoxide dismutase and serum levels of high sensitivity C-reactive protein, zinc, ceruloplasmin, matrix metalloproteinases 2 and 9, malondialdehyde and total antioxidant capacity. Data was analysed using descriptive statistical tests, paired and independent sample t-test. Results: The blood levels of glutathione peroxidase and superoxide dismutase and serum levels of total antioxidant capacity after exhaustive exercise in the supplemented group were significantly increased (p<0.05), while the content of matrix metalloproteinases 2 and 9, ceruloplasmin and malondialdehyde showed a significant decrease in comparison to the control group (p<0.05). Besides, there were no significant changes in other biochemical factors. Conclusion: Regular intake of pomegranate juice significantly modulates matrix metalloproteinases 2 and 9 serum levels of some inflammatory factors and thus protects against exhaustive exercise-induced oxidative injury in young healthy males.

    Transdiagnostic psychotherapies are designed to apply the same underlying treatment principles across a set of psychiatric disorders, without significant tailoring to specific diagnoses. Several transdiagnostic psychotherapy protocols have been developed recently, each of which has its own strengths and weaknesses. One promising treatment is Transdiagnostic Behaviour Therapy (TBT), in that it is one of the few transdiagnostic treatments to date shown to be effective in patients with depressive and anxiety disorders. However, TBT has only been investigated via individual psychotherapy. The present study investigated the effectiveness of a group protocol for TBT, compared with disorder-specific group psychotherapies, in a naturalistic setting. 109 participants with various diagnoses of affective disorders completed either group TBT (n = 37) or a disorder-specific group psychotherapy (n = 72). Measures included assessments of psychiatric symptomatology and transdiagnostic impairment at baseline and post-treatment. Overall, participants in the TBT group demonstrated significant improvements across all measures. When compared with disorder-specific groups, no statistical differences were observed between groups across symptoms; however, participants in the TBT group demonstrated roughly twice the treatment effect sizes in transdiagnostic impairment compared with participants in the disorder-specific groups. In addition, when participants from the most well-represented diagnosis and disorder-specific treatment (social anxiety disorder) were investigated separately, participants in the TBT group demonstrated significantly larger improvements in comorbid depressive symptoms than participants in the disorder-specific treatment. Pending replication and additional comparison studies, group TBT may provide an effective group treatment option for patients with affective disorders.

    Intradermal (ID) vaccination has been proposed as a cost-saving alternative for administration of Hepatitis B (HB) vaccine to implement of mass vaccination of high-risk groups, particularly in developing countries. Therefore, the effectiveness of ID vaccination needs to be evaluated and verified in different ethnic backgrounds. The present study is a randomized trail using a recombinant vaccine (Heberbiovac) to compare immunogenecity and safety of an intradermal low-dose (4 μg) with standard dose (20 μg) of intramuscular (IM) vaccination in healthy Iranian population. Participants were 143 healthy Iranian medical and nursing students randomly allocated to ID or IM vaccination group. The vaccine was inoculated at 0, 1 and 6 months intervals. Serum samples were collected 1 month after the last vaccination and the anti-HBs response was determined using ELISA. The overall seroprotection rate (anti-HBs level ≥ 10IU/L) was 97.3% for ID vaccination group, which was not different from that of IM vaccination group (98.55%)(p= 0.99). Similarly, geometric mean titers (GMT) of anti-HBs were not significantly different between ID (1164.1IU/L) and IM (1071.8IU/L) vaccination groups (p= 0.4). There was no significant difference in seroprotection rate and GMT of anti-HBs between sexes. Although induration and hyperpigmentation at the site of injection were more frequently observed in ID vaccination group, no other clinically adverse effects were observed in both vaccination groups. We conclude that the ID route, which would require one-fifth of the standard dose, would be suitable for use in certain groups such as high-risk adults when the cost of vaccine is the inhibiting factor for mass vaccination

    Background Immigrants and refugees to the United States exhibit lower dietary quality than the general population, but reasons for this disparity are poorly understood. In this study, we describe the meanings of food, health and wellbeing through the reported dietary preferences, beliefs, and practices of adults and adolescents from four immigrant and refugee communities in the Midwestern United States. Methods Using a community based participatory research approach, we conducted a qualitative research study with 16 audio-recorded focus groups with adults and adolescents who self-identified as Mexican, Somali, Cambodian, and Sudanese. Focus group topics were eating patterns, perceptions of healthy eating in the country of origin and in the U.S., how food decisions are made and who in the family is involved in food preparation and decisions, barriers and facilitators to healthy eating, and gender and generational differences in eating practices. A team of investigators and community research partners analyzed all transcripts in full before reducing data to codes through consensus. Broader themes were created to encompass multiple codes. Results Results show that participants have similar perspectives about the barriers (personal, environmental, structural) and benefits of healthy eating (e.g., ‘junk food is bad’). We identified four themes consistent across all four communities: Ways of Knowing about Healthy Eating (‘Meanings;’ ‘Motivations;’ ‘Knowledge Sources’), Eating Practices (‘Family Practices;’ ‘Americanized Eating Practices’ ‘Eating What’s Easy’), Barriers (‘Taste and Cravings;’ ‘Easy Access to Junk Food;’ ‘Role of Family;’ Cultural Foods and Traditions;’ ‘Time;’ ‘Finances’), and Preferences for Intervention (‘Family Counseling;’ Community Education;’ and ‘Healthier Traditional Meals.’). Some generational (adult vs. adolescents) and gender differences were observed. Conclusions Our study

    Owing to excessive worries regarding adverse cardiac events, hyperthermal balneotherapy for patients with coronary artery disease is underprescribed. However, very few cardiac events occur in similar heat stress during Finnish sauna bathing. Exercise testing has proven to be a safe diagnostic procedure even in survivors of myocardial infarction. We compared the effects of hyperthermal immersion and exercise testing on cardiac hemodynamics in 21 apparently healthy women aged 50-60 years. The maximal symptom-limited bicycle exercise test was performed according to the modified protocol of Wasserman. Hyperthermal immersion was carried out in 40 degrees C water and was completed by increasing the core temperature by about 2 degrees C. The left ventricular function was evaluated using continuous measurement of thoracic electric bioimpedance during both tests. The blood pressure, index of contractility and heart rate were measured directly, whereas the cardiac index, left cardiac work index and systemic vascular resistance index were calculated. The hemodynamic response, as assessed at continuous non-invasive monitoring, showed substantial differences between hyperthermal immersion and exercise testing. Overall, we found a significantly lower hemodynamic load during hyperthermal immersion in comparison with exercise testing. Entering the bath, there was a significant decrease in the left cardiac work, contractility and blood pressure. We recorded a slight increase in the heart rate towards peak hyperthermal immersion. However, other modulators such as the mean arterial pressure, index of contractility, cardiac index and left cardiac work index decreased even below resting values. Excessive hyperthermal immersion induced a lower hemodynamic load in apparently healthy women than standard maximal exercise testing.

    Full Text Available Objective: This study was an attempt to compare impulsive decision-making between AIDS sufferers, people suffering substance abuse, and nonclinical populations. Method: This was a causal-comparative study which was conducted within the six months of 2011. In this study, 30 AIDS sufferers, 30 drug abusers, and 30 healthy subjects from nonclinical population in the 15-67 age range were selected through convenience sampling. The selected participants were matched in terms of age, education, and gender. Barratt Impulsiveness Scale (1997 were administered to the three groups. Results: The results showed that there was a significant difference among the three groups in impulsivity subscales. Conclusion: The results showed that there existed some degree of deficiency in decision-making processes in AIDS sufferers and drug dependent persons. It may be rooted in a number of personality traits neurological damage drug use the insufficiency of appropriate training in life skills, problem-solving, and decision-making the availability of emotions at paly and personal and cultural thoughts and beliefs around protective behaviors in sexual relationships.

    Full Text Available Patients with chronic low back pain hold various perceptions, experiences and beliefs about their pain which are based on prior learning and social influence. This study was employed to earn perceptions and beliefs of patients regarding low back pain to apply in health education planning. Eight focus group discussions including 6-10 people taking part in each of them was performed. Subjects included volunteers who recruited from Rheumatology Research Center of Tehran University of Medical Science and met the criteria of being women, 18 years of age or older, having chronic low back pain diagnosed by physician and not having experience of surgical operation in last two years. Participants were interviewed regarding two themes: experiences of subjects about non-healthy behaviors resulted in low back pain and the causes of non-healthy behaviors. The results showed that the most common non healthy behavior was hard manual work with improper posture. About 50% of participants stated they had performed hard manual work because they did not have any knowledge about the effects and consequences of it. The rest of participants mentioned other factors such as lack of belief, positive attitude, skills and social support. This study proposes that in addition to knowledge, factors such as attitude, perceptions and beliefs of patients should be considered in health education planning.

    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.

    Full Text Available Background: 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. Patients and methods: We used the PAQ questionnaire with a group of asthmatic children attending hospital outpatient clinic and a group of healthy children matched for age. Results: 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. Conclusion: 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.

    The public health policy agenda oriented towards healthy ageing becomes the highest priority for the European countries. The article discusses the healthy ageing concept and its possible determinants with an aim to identify behavioral patterns related to healthy ageing in selected European countries. The healthy ageing is assessed based on a composite indicator of self-assessed health, functional capabilities and life meaningfulness. The logistic regression models are used to assess the impact of the healthy lifestyle index, psycho-social index and socio-economic status on the probability of healthy ageing (i.e. being healthy at older age). The lifestyle and psychosocial indexes are created as a sum of behaviors that might be important for healthy ageing. Models are analyzed for three age groups of older people: 60-67, 68-79 and 80+ as well as for three groups of countries representing Western, Southern and Central-Eastern Europe. The lifestyle index covering vigorous and moderate physical activity, consumption of vegetables and fruits, regular consumption of meals and adequate consumption of liquids is positively related to healthy ageing, increasing the likelihood of being healthy at older age with each of the items specified in the index. The score of the index is found to be significantly higher (on average by 1 point for men and 1.1 for women) for individuals ageing healthily. The psychosocial index covering employment, outdoor social participation, indoor activities and life satisfaction is also found to be significantly related to health increasing the likelihood of healthy ageing with each point of the index score. There is an educational gradient in healthy ageing in the population below the age of 68 and in Southern and Central-Eastern European countries. In Western European countries, income is positively related to healthy ageing for females. Stimulation physical activity and adequate nutrition are crucial domains for a well-defined public health policy

    Full Text Available Introduction: Breast Cancer is one of the most important fatal cancers in women. The mean age of breast cancer in Iran is 48.8 years which is very lower than other countries. Selenium can play an important role in reduction of cancer in several ways, for example selenium increases immunity response and protects cells from oxidation of free radicals and also decreases carcinogenic metabolites. Breast cancer is one of the most important cancers in our country because its incidence is very high and the mean age of patients is very low. Different studies have shown the benefits of selenium in prevention of cancer and since many years selenium has been used as a dietary supplement in advanced countries. Several studies regarding relationship between selenium levels and breast cancer have been done in different countries. We therefore planned a study to evaluate serum selenium levels in breast cancer patients and compare them with a healthy control group. Methods: We selected 45 patients younger than 48 years old and 33 patients older than 48 years old who had not yet received any therapy (surgery, chemotherapy, etc for their cancer as a case group and 46 healthy people who were matched with the patients as a control group and included 23 persons younger and 23 persons older than 48 years old. From each participant, 5cc blood was derived and in several stages, serum selenium levels were evaluated using atomic absorption technology. Data about type of cancer, stage, grade, IHC and cigarette smoking were also collected. Results: The mean Se level was 161.20 μg/l (SD=46.27 μg/l in the patients and 189.13 μg/l (SD=48.75 μg/l in the control group that was statistically significant (P48 years old was 155.39 μg/l (SD=46.68 μg/l that was lower than the control groups. Difference in serum selenium levels between patients and controls in the older group was significant (P=0.007, but in the younger group, it was not statistically significant (P=0

  19. Assessing the Accuracy of Generalized Inferences From Comparison Group Studies Using a Within-Study Comparison Approach: The Methodology.

    2016-06-01

    Various studies have examined bias in impact estimates from comparison group studies (CGSs) of job training programs, and in education, where results are benchmarked against experimental results. Such within-study comparison (WSC) approaches investigate levels of bias in CGS-based impact estimates, as well as the success of various design and analytic strategies for reducing bias. This article reviews past literature and summarizes conditions under which CGSs replicate experimental benchmark results. It extends the framework to, and develops the methodology for, situations where results from CGSs are generalized to untreated inference populations. Past research is summarized; methods are developed to examine bias in program impact estimates based on cross-site comparisons in a multisite trial that are evaluated against site-specific experimental benchmarks. Students in Grades K-3 in 79 schools in Tennessee; students in Grades 4-8 in 82 schools in Alabama. Grades K-3 Stanford Achievement Test (SAT) in reading and math scores; Grades 4-8 SAT10 reading scores. Past studies show that bias in CGS-based estimates can be limited through strong design, with local matching, and appropriate analysis involving pretest covariates and variables that represent selection processes. Extension of the methodology to investigate accuracy of generalized estimates from CGSs shows bias from confounders and effect moderators. CGS results, when extrapolated to untreated inference populations, may be biased due to variation in outcomes and impact. Accounting for effects of confounders or moderators may reduce bias. © The Author(s) 2016.

    Comparison of sequential pulmonary function tests in the same individual can be used to assess progression of a disease, response to therapy, or response to bronchial provocation. These types of comparisons require an understanding of the factors influencing the variability normally in repeat measurements of lung function. To avoid misleading conclusions about changes in serial measurements, the degree of variability of each test must be considered in their interpretation. The purpose of this study was to examine the degree of intrasubject variability for pulmonary function testing in healthy, asthmatic and children with chronic lung disease (CLD). The tests examined were spirometry, and body plethysmography determination of lung volumes. We studied 21 healthy children, 19 asthmatic patients and 19 children with CLD, testing were done on nine occasions, three times within a day, on three different days, over a period of two months. Short-term variability was defined as the coefficient of variation for the s ix measurements made on days 1 and 2, and the long-term variability as the CV of the nine measurements made on days 1, 2 and 3. Based on the CV measures, children with CLD had significantly more variability in all spirometric values compared with healthy and asthmatic children, except for PEF (P< 0.05) children with CLD had a significantly lower CV for TGV and FRC compared with the other two groups (p < 0.05). Asthmatic children had a significantly higher CV for RV and RV/TLC compared with healthy and children with CLD (p < 0.05). We propose a method to consider changes in pulmonary function tests as significant. The degree of variability and an estimate of the percent change for significance of spirometric and plethysmographic tests must be considered in the interpretation of data to avoid misleading conclusions. The variability of spirometric pulmonary function data in healthy subjects was smaller than that for patients with pulmonary disease, so larger

    The purpose of the present study was to examine the ability of the Contextual Memory Test (CMT) to differentiate between elderly people suffering from Alzheimer's disease (AD) in comparison to healthy elderly people. Specifically, the objectives were to compare for differences between and within the groups on components of memory, including immediate and delayed recall as well as recognition. In addition, parameters of metamemory skills, such as general awareness, self-prediction of memory capacity, self-estimation, strategy use and use of contextual information, as well as the correlation between self-awareness and actual performance in both groups, were investigated. The sample consisted of 60 elderly participants, including 30 people diagnosed with AD who were assigned to the research group and 30 people matched for age, gender and educational level who were assigned to the control group. The results provide support for the hypothesis positing differences in memory performance between healthy elderly participants and those suffering from AD, particularly in immediate and delayed recall as well as in recognition. Moreover, findings indicate an improvement in memory performance under the cued condition (contextual), whereas improvement in the AD group proved to be significant only for immediate recall. The findings point to a distinct overestimation of memory ability predicted by both the AD and control groups. Following the memory task, however, the participants accurately estimated the number of items they remembered. In addition, significant correlations between the use of contextual and association strategies and the number of items remembered by both groups were obtained, in immediate as well as in delayed recall. Therefore, these findings support the CMT as a valuable memory and metamemory assessment tool for use with the AD population.

    Full Text Available Objectives: Regarding the implication of viruses particularly herpes in pemphigus vulgaris, we sought to assess and compare the level of immunoglobulin G (IgG antibodies against herpes simplex virus types 1 and 2 (HSV1 and HSV2, cytomegalovirus (CMV and Epstein-Barr virus (EBV in patients with pemphigus vulgaris and healthy people.    Materials and Methods: In this cross-sectional study, 25 patients with pemphigus vulgaris and 27 healthy individuals comprised the experimental and control groups, respectively. Serum samples were taken from both groups; the levels of IgG antibodies against HSV1, HSV2, CMV and EBV were measured using ELISA.  Results: Immunoglobulin G titer was higher for all four viruses in the patient group in comparison to the control group. This difference was significant for anti-EBV (P= 0.005, anti-CMV (P=0.0001 and anti-HSV2 (P=0.001 but not significant for anti-HSV1 (P= 0.36.Conclusion: Viruses including EBV, CMV, and HSV2 probably play a role in the pathogenesis of pemphigus in addition to the effects of genetics, toxins and other predisposing factors. In this study, no statistically significant relationship was observed between HSV1 and pemphigus vulgaris, which was probably due to the high titer of anti-HSV1 IgG in healthy individuals in the community. More studies must be done in this regard.

    Full Text Available Abstract Background Virtual reality (VR is an innovative tool for sensorimotor rehabilitation increasingly being employed in clinical and community settings. Despite the growing interest in VR, few studies have determined the validity of movements made in VR environments with respect to real physical environments. The goal of this study was to compare movements done in physical and virtual environments in adults with motor deficits to those in healthy individuals. Methods The participants were 8 healthy adults and 7 adults with mild left hemiparesis due to stroke. Kinematics of functional arm movements involving reaching, grasping and releasing made in physical and virtual environments were analyzed in two phases: 1 reaching and grasping the ball and 2 ball transport and release. The virtual environment included interaction with an object on a 2D computer screen and haptic force feedback from a virtual ball. Temporal and spatial parameters of reaching and grasping were determined for each phase. Results Individuals in both groups were able to reach, grasp, transport, place and release the virtual and real ball using similar movement strategies. In healthy subjects, reaching and grasping movements in both environments were similar but these subjects used less wrist extension and more elbow extension to place the ball on the virtual vertical surface. Participants with hemiparesis made slower movements in both environments compared to healthy subjects and during transport and placing of the ball, trajectories were more curved and interjoint coordination was altered. Despite these differences, patients with hemiparesis also tended to use less wrist extension during the whole movement and more elbow extension at the end of the placing phase. Conclusion Differences in movements made by healthy subjects in the two environments may be explained by the use of a 2D instead of a 3D virtual environment and the absence of haptic feedback from the VR target

    Full Text Available Aims: Leptin is one of the most important fat-derived hormones. Several studies have shown that serum leptin levels in systemic inflammatory diseases are reduced. The aim of this study was to evaluate the serum leptin levels in three groups: patients with active pulmonary tuberculosis (TB, patients with non-pulmonary infections (acute pneumonia and normal people. Materials & Methods: In this cross-sectional study, in 2010, 40 patients with active pulmonary TB (case group and 40 patients with non-pulmonary infections (positive control group admitted to Boo-Ali hospital in Zahedan and 40 healthy subjects (negative control group were selected using easy access and serum leptin levels were evaluated by ELISA. Data were analyzed by SPSS 18 software and one-way ANOVA. Findings: The mean of serum leptin levels in patients with non-pulmonary infections (p=0.030 and in patients with active pulmonary TB (p=0.004 were significantly lower than normal group, but the mean of serum leptin levels in patients with active pulmonary TB and patients with non-pulmonary infections were not significantly different (p=0.555. Conclusion: Serum leptin levels are lower in patients with active pulmonary tuberculosis and in patients with non-pulmonary infections than in normal people, but there is no difference between patients with active pulmonary tuberculosis and patients with non-pulmonary infections. Therefore, serum leptin levels are not an appropriate marker for the differentiation of active pulmonary tuberculosis from pulmonary infections (acute pneumonia.

    It is commonly assumed that early emotional signals provide relevant information for social cognition tasks. The goal of this study was to test the association between (a) cortical markers of face emotional processing and (b) social-cognitive measures, and also to build a model which can predict this association (a and b) in healthy volunteers as well as in different groups of psychiatric patients. Thus, we investigated the early cortical processing of emotional stimuli (N170, using a face and word valence task) and their relationship with the social-cognitive profiles (SCPs, indexed by measures of theory of mind, fluid intelligence, speed processing and executive functions). Group comparisons and individual differences were assessed among schizophrenia (SCZ) patients and their relatives, individuals with attention deficit hyperactivity disorder (ADHD), individuals with euthymic bipolar disorder (BD) and healthy participants (educational level, handedness, age and gender matched). Our results provide evidence of emotional N170 impairments in the affected groups (SCZ and relatives, ADHD and BD) as well as subtle group differences. Importantly, cortical processing of emotional stimuli predicted the SCP, as evidenced by a structural equation model analysis. This is the first study to report an association model of brain markers of emotional processing and SCP. © The Author (2013). Published by Oxford University Press.

    In an attempt to better understand the nature of emotion dysregulation in the daily lives of persons with a borderline personality disorder (BPD), Houben et al. (2016) recently identified emotional switching, which refers to the tendency to make large changes between positive and negative emotional states over time, as a possible defining characteristic of the emotion dynamics observed in BPD. The goal of this study was to examine the specificity of these previous findings in 2 samples by comparing BPD patients (N = 43 in sample 1; N = 81 in sample 2) to patients with bulimia nervosa (N = 20), posttraumatic stress disorder (N = 28), or healthy controls (N = 28) in sample 1, and to patients with depressive disorder (N = 50) in sample 2, with respect to measures of emotional switching. Analyses of these 2 experience sampling datasets revealed that contrary to expectations, BPD patients did not differ from the clinical groups regarding their mere tendency to switch between positive and negative emotional states on consecutive moments over time and regarding the magnitude of such changes between positive and negative emotional states over time. However, all clinical groups did differ from healthy controls regarding all switch measures in dataset 1. These results indicate that emotional switching, similar to other more traditional indicators of overall changes in emotional intensity in daily life, might reflect a feature of emotional responding characterizing a range of disorders with mood disturbances.

    We used tensor-based morphometry (TBM) to: 1) map gray matter (GM) volume changes associated with motor learning in young healthy individuals; 2) evaluate if GM changes persist three months after cessation of motor training; and 3) assess whether the use of different schemes of motor training during the learning phase could lead to volume modifications of specific GM structures. From 31 healthy subjects, motor functional assessment and brain 3D T1-weighted sequence were obtained: before motor training (time 0), at the end of training (two weeks) (time 2), and three months later (time 3). Fifteen subjects (group A) were trained with goal-directed motor sequences, and 16 (group B) with non purposeful motor actions of the right hand. At time 1 vs. time 0, the whole sample of subjects had GM volume increase in regions of the temporo-occipital lobes, inferior parietal lobule (IPL) and middle frontal gyrus, while at time 2 vs. time 1, an increased GM volume in the middle temporal gyrus was seen. At time 1 vs. time 0, compared to group B, group A had a GM volume increase of the hippocampi, while the opposite comparison showed greater GM volume increase in the IPL and insula in group B vs. group A. Motor learning results in structural GM changes of different brain areas which are part of specific neuronal networks and tend to persist after training is stopped. The scheme applied during the learning phase influences the pattern of such structural changes.

    Full Text Available Background. The present study aimed to compare plasma levels of cortisol, testosterone, dehydroepiandrosterone (DHEA, and prolactin in patients with schizophrenia and healthy individuals. Method. A total of 100 patients with schizophrenia disorder (69 men and 31 women and 190 healthy individuals (94 men and 96 women participated in this cross-sectional study. They were tested for hormone levels and completed demographic questionnaires. Data were analyzed using multivariate analysis of variance (MANOVA and one-way analysis of variance. Results. Serum testosterone level was significantly higher in men with schizophrenia than in healthy men. Women with schizophrenia had a significantly higher level of testosterone and lower level of prolactin compared to healthy women. There were no significant differences in hormone levels across various subtypes of schizophrenia. No significant differences also were observed in hormones levels in patients with first-episode schizophrenia disorder compared to those in patients with recurrent episodes. Conclusion. This study indicated that abnormal testosterone and prolactin levels might be associated with pathophysiology of schizophrenia disorder.

    The aim of the current study is to identify strategies to promote healthy eating in young children that can be applied by caregivers, based on their own perceptions of effectiveness and feasibility. Whereas previous research mainly focused on parental influences on children's eating behavior, the growing role of other caregivers in the upbringing of children can no longer be denied. Four focus groups were conducted with three types of caregivers of post-weaning children under 6 years old: parents (n = 14), family child care providers (n = 9), and daycare assistants (n = 10). The audiotaped focus group discussions were transcribed and imported into Nvivo 10.0 for thematic analysis. The behaviors put forward by the caregivers were categorized within three broad dimensions: global influences, general behaviors, and specific feeding practices. Perceived effective strategies to promote healthy eating behavior in children included rewards, verbal encouragement, a taste-rule, sensory sensations, involvement, variation, modeling, repeated exposure, and a peaceful atmosphere. Participants mainly disagreed on the perceived feasibility of each strategy, which largely depended on the characteristics of the caregiving setting (e.g. infrastructure, policy). Based on former research and the current results, an intervention to promote healthy eating behaviors in young children should be adapted to the caregiving setting or focus on specific feeding practices, since these involve simple behaviors that are not hindered by the limitations of the caregiving setting. Due to various misconceptions regarding health-promoting strategies, clear instructions about when and how to use these strategies are necessary.

    Full Text Available Objective. The aim of this randomized controlled study was to investigate the effects of insoles with a toe-grip bar on toe function and standing balance in healthy young women. Methods. Thirty female subjects were randomly assigned to an intervention group or a control group. The intervention group wore shoes with insoles with a toe-grip bar. The control group wore shoes with general insoles. Both groups wore the shoes for 4 weeks, 5 times per week, 9 hours per day. Toe-grip strength, toe flexibility, static balance (total trajectory length and envelope area of the center of pressure, and dynamic balance (functional reach test were measured before and after the intervention. Results. Significant interactions were observed for toe-grip strength and toe flexibility (F=12.53, p<0.01; F=5.84, p<0.05, resp., with significant improvement in the intervention group compared with that in the control group. Post hoc comparisons revealed that both groups showed significant improvement in toe-grip strength (p<0.01 and p<0.05, resp., with higher benefits observed for the intervention group (p<0.01. Conversely, no significant interaction was observed in the total trajectory length, envelope area, and functional reach test. Conclusions. This study suggests that insoles with a toe-grip bar contribute to improvements in toe-grip strength and toe flexibility in healthy young women.

    While corner store-based nutrition interventions have emerged as a potential strategy to increase healthy food availability in low-income communities, few evaluation studies exist. We present the results of a trial in Baltimore City to increase the availability and sales of healthier food options in local stores. Quasi-experimental study. Corner stores owned by Korean-Americans and supermarkets located in East and West Baltimore. Seven corner stores and two supermarkets in East Baltimore received a 10-month intervention and six corner stores and two supermarkets in West Baltimore served as comparison. During and post-intervention, stocking of healthy foods and weekly reported sales of some promoted foods increased significantly in intervention stores compared with comparison stores. Also, intervention storeowners showed significantly higher self-efficacy for stocking some healthy foods in comparison to West Baltimore storeowners. Findings of the study demonstrated that increases in the stocking and promotion of healthy foods can result in increased sales. Working in small corner stores may be a feasible means of improving the availability of healthy foods and their sales in a low-income urban community.

    Full Text Available PURPOSE: Genevac B, a new indigenous recombinant hepatitis B vaccine was evaluated for its immunogenicity and safety in comparison with Engerix B (Smithkline Beecham Biologicals, Belgium and Shanvac B (Shantha Biotechnics, India in healthy adult volunteers. METHODS: While 240 study subjects were included in the Genevac B group, 80 each were the subjects for Engerix B and Shanvac B. A three dose regimen of 0,1,2 months was adopted with 20 gm dosage uniformly in all the three groups. Vaccinees were assessed during prevaccination, followup and post vaccination periods for clinical, haematological, biochemical and immunological parameters for safety and immunogenicity. RESULTS: Successful follow-up in all parameters for four months could be achieved in 92.5% (222/240 for Genevac B study subjects and the same was 85% (68/80 and 80% (64/80 for Engerix B and Shanvac B respectively. While 100% seroconversion was observed in all the three groups, the rate of seroprotectivity was 99.5% by Genevac B, 98.5% by Engerix B and 98.4% for Shanvac B. However the difference was not statistically significant (p>0.05. The GMT values of anti HBs after one month of completion of the vaccination were 735.50, 718.23 and 662.20 mIU/mL respectively. No systemic reaction was either seen or reported by the volunteers during the vaccination process of Genevac B and other two vaccines. Clinical, haematological and biochemical safety parameters remained within normal limits throughout the study period. CONCLUSION: The study confirms that Genevac B, the new recombinant Hepatitis B vaccine has the acceptable international standards of safety and immunogenicity.

    Stability for up to 6 days' storage of erythrocyte and reticulocyte parameters in samples from iron-deficient and thalassemic individuals has not yet been reported. This lack of knowledge challenges evaluation of the full blood count in referral samples for hemoglobinopathy evaluation. We therefore hereby present such sample stability data. We included fresh (less than 4 hours old) blood samples from eight healthy, eight iron-deficient, and 11 thalassemic individuals. A full blood count, including reticulocyte parameters, was performed on a Sysmex XE-2100 once daily during a 6-day storage period at room temperature. For healthy individuals, we also studied stability of refrigerated samples and investigated analytical and biological variation. Hemoglobin concentration, erythrocyte count, and mean corpuscular hemoglobin were stable for 6 days in all diagnostic groups. Mean corpuscular volume increased less in samples from iron-deficient individuals while the number of reticulocytes increased more in samples from thalassemic, as compared to healthy individuals. Ret-He stability depended on its baseline value. Within-person biological variation in samples from healthy individuals was low both for erythrocyte parameters and for reticulocyte hemoglobin, while higher for reticulocyte counts. Results for hemoglobin concentration, erythrocyte count, and mean corpuscular hemoglobin are reliable in hemoglobinopathy investigation of referred samples for up to 6 days. Storage time-dependent changes of other erythrocyte and reticulocyte parameters in blood samples from iron-deficient and thalassemic individuals differ from those of healthy individuals.

    2009-01-01

    BACKGROUND: Global mean (GM) normalization is one of the most commonly used methods of normalization in PET and SPECT group comparison studies of neurodegenerative disorders. It requires that no between-group GM difference is present, which may be strongly violated in neurodegenerative disorders....... Importantly, such GM differences often elude detection due to the large intrinsic variance in absolute values of cerebral blood flow or glucose consumption. Alternative methods of normalization are needed for this type of data. MATERIALS AND METHODS: Two types of simulation were performed using CBF images...

    Though the benefits of healthy lifestyle choices are well-established among the general population, less is known about how developing and adhering to healthy lifestyle habits benefits obese versus normal weight or overweight individuals. The purpose of this study was to determine the association between healthy lifestyle habits (eating 5 or more fruits and vegetables daily, exercising regularly, consuming alcohol in moderation, and not smoking) and mortality in a large, population-based sample stratified by body mass index (BMI). We examined the association between healthy lifestyle habits and mortality in a sample of 11,761 men and women from the National Health and Nutrition Examination Survey III; subjects were ages 21 and older and fell at various points along the BMI scale, from normal weight to obese. Subjects were enrolled between October 1988 and October 1994 and were followed for an average of 170 months. After multivariable adjustment for age, sex, race, education, and marital status, the hazard ratios (95% CIs) for all-cause mortality for individuals who adhered to 0, 1, 2, or 3 healthy habits were 3.27 (2.36-4.54), 2.59 (2.06-3.25), 1.74 (1.51-2.02), and 1.29 (1.09-1.53), respectively, relative to individuals who adhered to all 4 healthy habits. When stratified into normal weight, overweight, and obese groups, all groups benefited from the adoption of healthy habits, with the greatest benefit seen within the obese group. Healthy lifestyle habits are associated with a significant decrease in mortality regardless of baseline body mass index.

    Our study was aimed to investigate anesthetic effects of propofol in patients with different blood groups.A total of 72 participants were enrolled from patients arranged for surgeries of cholecystectomy, tonsillectomy, and spinal operation. Each blood group (A, B, AB, and O) contained 18 participants. Mean arterial pressure (MAP), heart rate (HR), and bispectral index (BIS) were assayed with Philips monitor. These indexes were observed before propofol anesthesia (T0), and then were recorded when concentration of propofol was 1 μg/mL (T1), 2 μg/mL (T2), 3 μg/mL (T3), and 4 μg/mL (T4). The differences in MAP, HR, and BIS at T0 among groups were compared with the χ test. Multiple comparisons were adopted to calculate the differences in MAP, HR, and BIS between groups at T1, T2, T3, and T4.No significant differences in age, sex, and weight of all groups were found (P > .05). Before propofol anesthesia (T0), all the participants exhibited no differences in MAP, HR, and BIS (P > .05). Subsequently, we found obvious differences in ΔMAP, ΔHR, and ΔBIS between groups. The patients in the B blood group showed highest ΔMAP and ΔHR at each time point (P blood group exhibited highest value at T3 and T4 (P blood group remarkably affects the anesthetic effects of propofol.

    The role of bacteriophages in influencing the structure and function of the healthy human gut microbiome is unknown. With few exceptions, previous studies have found a high level of heterogeneity in bacteriophages from healthy individuals. To better estimate and identify the shared phageome of humans, we analyzed a deep DNA sequence dataset of active bacteriophages and available metagenomic datasets of the gut bacteriophage community from healthy individuals. We found 23 shared bacteriophages in more than one-half of 64 healthy individuals from around the world. These shared bacteriophages were found in a significantly smaller percentage of individuals with gastrointestinal/irritable bowel disease. A network analysis identified 44 bacteriophage groups of which 9 (20%) were shared in more than one-half of all 64 individuals. These results provide strong evidence of a healthy gut phageome (HGP) in humans. The bacteriophage community in the human gut is a mixture of three classes: a set of core bacteriophages shared among more than one-half of all people, a common set of bacteriophages found in 20-50% of individuals, and a set of bacteriophages that are either rarely shared or unique to a person. We propose that the core and common bacteriophage communities are globally distributed and comprise the HGP, which plays an important role in maintaining gut microbiome structure/function and thereby contributes significantly to human health.

    Self-administered foot reflexology is unrestricted by time and space, economical, and practical because it is easy to learn and apply. This study estimated the effectiveness of self-foot reflexology for symptom management in healthy persons through a systematic review and meta-analysis. The participants were healthy persons not diagnosed with a specific disease. The intervention was foot reflexology administered by participants, not by practitioners or healthcare providers. The comparative studies either between groups or within group comparison were included. Our search utilized core databases (MEDLINE, EMBASE, Cochrane, and CINAHL). We also searched Chinese (CNKI), Japanese (J-STAGE), and Korean databases (KoreaMed, KMbase, KISS, NDSL, KISTI, and OASIS). The search was used MeSH terminology and key words (foot reflexology, foot massage, and self). Analysis of three non-randomized trials and three before-and-after studies showed that self-administered foot reflexology resulted in significant improvement in subjective outcomes such as perceived stress, fatigue, and depression. However, there was no significant improvement in objective outcomes such as cortisol levels, blood pressure, and pulse rate. We did not find any randomized controlled trial. This study presents the effectiveness of self-administered foot reflexology for healthy persons' psychological and physiological symptoms. While objective outcomes showed limited results, significant improvements were found in subjective outcomes. However, owing to the small number of studies and methodological flaws, there was insufficient evidence supporting the use of self-performed foot reflexology. Well-designed randomized controlled trials are needed to assess the effect of self-administered foot reflexology in healthy people. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Non-steroidal anti-inflammatory drugs (NSAIDs inhibit COX enzyme activity, a significant mechanism of action of NSAIDs. Inflammation is associated with increasing cancer incidence. Recent pre-clinical and clinical studies have shown that NSAID treatment could cause an anti-tumour effect in cancers. Such studies are lengthy and expensive. The present study, however, examined DNA damage in the Comet and micronucleus assays in peripheral blood lymphocytes of patients with respiratory diseases and healthy individuals using the nanoparticle (NP and bulk versions of the NSAIDs, aspirin and ibuprofen. Lymphocytes are suitable surrogate cells for cancers and other disease states. DNA damage decreased in lymphocytes from healthy individuals, asthma, COPD and lung cancer patient groups after treatment with aspirin nano-suspension (ASP N and ibuprofen nano-suspension (IBU N compared to their bulk version (micro-suspension in both assays. However, when ASP N was compared to untreated lymphocytes in all groups in the Comet assay, DNA damage significantly decreased in all groups, except the asthma group. When IBU N was compared to untreated lymphocytes, in healthy individuals and the lung cancer group, DNA damage decreased, but increased in asthma and COPD groups. Similarly, micronuclei (MNi increased after ASP N and IBU N in the healthy individual and lung cancer groups, and decreased in asthma and COPD groups. Also shows that whilst there are basic similarities with different genetic endpoints in terms of nano and bulk forms, but highlights some differences between the disease states examined. Furthermore, lymphocyte responses after IBU N and ibuprofen bulk were investigated by patch-clamp experiments demonstrating that IBU N inhibited ion channel activity by 20%. This molecular epidemiology approach mirrors pre-clinical and clinical findings, and provides new information using nanoparticles.

    Full Text Available Purpose: Urologic diseases affected by testosterone can be associated with smaller penis size compared to the normal population. We sought to compare penile length in children with unilateral cryptorchidism and normative data from a cohort of healthy Korean boys. Materials and Methods: This study was performed in 259 Korean boys (212, normal cohort; 47, cryptorchidism aged 6–24 months, each of whom had been brought to an outpatient clinic at one of five tertiary hospitals (Gyeongsangnam-do Province between April 2014 and June 2015. Penile length was measured via stretched penile length (SPL and testicular size was measured using orchidometry (mL. Results: SPL in children with cryptorchidism was significantly shorter compared to a cohort of healthy Korean boys aged 6–24 months (3.7±0.5 cm and 4.3±0.8 cm, p<0.001, although there were no differences with regard to height, body weight and contralateral testicular size between the two groups. According to the stratified ages (6–12, 12–18, and 18–24 months, SPL in children with cryptorchidism was persistently shorter at their ages than those without. Conclusions: It might be that the penile length aged 6–24 months of children with unilateral cryptorchidism is shorter than that of a cohort of healthy Korean boys.

    Downer cow syndrome (DCS) is often diagnosed in dairy cattle during the early post-partum period. The etiology of this condition is not completely understood, as it can be related to the energetic or electrolyte metabolism, as well as to infectious diseases or to trauma. The aim of this study is to compare energy metabolism and insulin sensitivity indices and various biochemical parameters between recumbent and healthy dairy cows. A prospective study has been undertaken on 361 recumbent and 80 healthy Holstein cows. Plasmatic glucose, insulin, non-esterified fatty acid (NEFA) and β-hydroxybutyrate (BHB) were assayed in all cows in order to calculate the insulin sensitivity indices but also minerals (Calcium, Phosphorous and Magnesium), thyroxin and creatine kinase. Body Condition Scores (BCS) was assessed. Significant differences in NEFA, and the glucose and insulin sensitivity indices ("Homeostasis Model Assessment" HOMA, "Revised Quantitative Insulin Sensitivity Check Index" RQUICKI, RQUICKI-BHB) were observed between healthy and recumbent cows in the early post-parturient period indicating disturbances of glucose and insulin homeostasis in the recumbent cows. In the same manner, mineral concentrations were significantly different between healthy and recumbent cows. Glucose, insulin NEFA, and HOMA, were different between early post-partum downer cows and the DCS-affected cows later in lactation. Results indicate disturbances in energy homeostasis in DCS-affected dairy cows. Further research should determine a prognostic value of the indices in cows suffering from recumbency of metabolic origin.

    A core operational definition of active and healthy aging (AHA) is needed to conduct comparisons. A conceptual AHA framework proposed by the European Innovation Partnership on Active and Healthy Ageing Reference Site Network includes several items such as functioning (individual capability and underlying body systems), well-being, activities and participation, and diseases (including noncommunicable diseases, frailty, mental and oral health disorders). The instruments proposed to assess the conceptual framework of AHA have common applicability and availability attributes. The approach includes core and optional domains/instruments depending on the needs and the questions. A major common domain is function, as measured by the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). WHODAS 2.0 can be used across all diseases and healthy individuals. It covers many of the AHA dimensions proposed by the Reference Site network. However, WHODAS 2.0 does not include all dimensions proposed for AHA assessment. The second common domain is health-related quality of life (HRQoL). A report of the AHA questionnaire in the form of a spider net has been proposed to facilitate usual comparisons across individuals and groups of interest. Copyright © 2015.

    Full Text Available Abstract Background The Healthy Options for Nutrition Environments in Schools (Healthy ONES study was an evidence-based public health (EBPH randomized group trial that adapted the Institute for Healthcare Improvement’s (IHI rapid improvement process model to implement school nutrition policy and environmental change. Methods A low-income school district volunteered for participation in the study. All schools in the district agreed to participate (elementary = 6, middle school = 2 and were randomly assigned within school type to intervention (n = 4 and control (n =4 conditions following a baseline environmental audit year. Intervention goals were to 1 eliminate unhealthy foods and beverages on campus, 2 develop nutrition services as the main source on campus for healthful eating (HE, and 3 promote school staff modeling of HE. Schools were followed across a baseline year and two intervention years. Longitudinal assessment of height and weight was conducted with second, third, and sixth grade children. Behavioral observation of the nutrition environment was used to index the amount of outside foods and beverages on campuses. Observations were made monthly in each targeted school environment and findings were presented as items per child per week. Results From an eligible 827 second, third, and sixth grade students, baseline height and weight were collected for 444 second and third grade and 135 sixth grade students (51% reach. Data were available for 73% of these enrolled students at the end of three years. Intervention school outside food and beverage items per child per week decreased over time and control school outside food and beverage items increased over time. The effects were especially pronounced for unhealthy foods and beverage items. Changes in rates of obesity for intervention school (28% baseline, 27% year 1, 30% year 2 were similar to those seen for control school (22% baseline, 22% year 1, 25% year 2 children

    Full Text Available Objectives: Nowadays, a lot of attention has been paid to the therapeutic properties of herbs, including evaluation of the effects of these plants on fertility in laboratory animals. Apium graveolens L. (celery has been widely used in traditional medicine for treatment of various disorders including impotency. Therefore, this study was designed to investigate the effects of aqueous extract of A. graveolens on testicular tissue and spermatogenesis in healthy male rats. Materials and Methods: In this research, 24 apparently healthy male rats were divided into three groups, including eight rats in each. The first group as control received only distilled water 1 ml/animal/day. The second and third groups orally received 100 and 200 mg/kg b.w. of the extract, respectively, for 30 days. The day after the last administration of the extract, the rats were sacrificed, the testes were removed entirely, and the morphometric studies were carried out. Epididymal sperm count and histological studies of testicular tissue were conducted. Results: The comparison between the treated and control groups revealed a remarkable increase in the seminiferous tubules diameter, testes volume (p≤0.001, and the number of spermatogonia, primary spermatocytes and spermatozoa. Furthermore, the increase in the number of spermatids and epididymal weight were only significant at high doses of the extract (p≤ 0.05. Conclusions: The results from this study indicated that administration of celery leaf extract may improve spermatogenesis process and also be useful for some sperm fertility parameters.

    To date, it is unclear how consumers evaluate the healthiness of individual foods and meals and how consumers' perceptions are related to expert opinions. This knowledge is essential for efficient communication of nutrition information with the goal of promoting healthy eating. This study used the fake food buffet method to investigate health perceptions of selected meals and of 54 individual foods and beverages. Lay consumers' subjective healthiness evaluations of meals and foods were compared to objective nutrient profile scores, which were previously shown to correlate highly with expert opinions. The results show that nutrition profile scores and lay evaluations were highly correlated, which indicates that lay people used similar criteria as experts to evaluate the healthiness of foods. However, lay consumers tended to neglect the amount of saturated fat, protein and sodium for their judgments. Also, it was found that while lay consumers were quite able to evaluate single food products, they had difficulties in evaluating entire meals. Future interventions should focus particularly on educating the consumer about the negative effects of diets high in salt and saturated fat and they should improve the consumer's abilities to evaluate entire meals.

    Full Text Available Overwhelming evidence reveals the close link between unwarranted weight gain among childbearing women and childhood adiposity. Yet current barriers limit the capacity of perinatal health care providers (PHCPs to offer healthy lifestyle counselling. In response, today’s Internet savvy women are turning to online resources to access health information, with the potential of revolutionising health services by enabling PHCPs to guide women to appropriate online resources. This paper presents the findings of a project designed to develop an online resource to promote healthy lifestyles during the perinatal period. The methodology involved focus groups and interviews with perinatal women and PHCPs to determine what online information was needed, in what form, and how best it should be presented. The outcome was the development of the Healthy You, Healthy Baby website and smartphone app. This clinically-endorsed, interactive online resource provides perinatal women with a personalised tool to track their weight, diet, physical activity, emotional wellbeing, and sleep patterns based on the developmental stage of their child with links to quality-assured information. One year since the launch of the online resource, data indicates it provides a low-cost intervention delivered across most geographic and socioeconomic strata without additional demands on health service staff.

    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.

    Social cognition is impaired in schizophrenia but it is not clear whether this is specific for the illness and whether emotion perception is selectively affected. To study this we examined the perception of emotional and non-emotional clues in facial expressions, a key social cognitive skill, in schizophrenia patients and old healthy individuals using young healthy individuals as reference. Tests of object recognition, visual orientation, psychomotor speed, and working memory were included to allow multivariate analysis taking into account other cognitive functions Schizophrenia patients showed impairments in recognition of identity and emotional facial clues compared to young and old healthy groups. Severity was similar to that for object recognition and visuospatial processing. Older and younger healthy groups did not differ from each other on these tests. Schizophrenia patients and old healthy individuals were similarly impaired in the ability to automatically learn new faces during the testing procedure (measured by the CSTFAC index) compared to young healthy individuals. Social cognition is distinctly impaired in schizophrenia compared to healthy aging. Further study is needed to identify the mechanisms of automatic social cognitive learning impairment in schizophrenia patients and healthy aging individuals and determine whether similar neural systems are affected.

    β-Thalassemia is one of the most common inherited disorders and is widely distributed throughout the world. Owing to severe deficiencies in red blood cell production, blood transfusion is required to correct anemia for normal growth and development but causes additional complications owing to iron overload. The aim of this study is to quantify the biometal dysregulations in β-thalassemia patients as compared with healthy controls. A total of 17 elements were analyzed in serum samples of β-thalassemia patients and healthy controls using ICP-MS followed by chemometric analyses. Out of these analyzed elements, 14 showed a significant difference between healthy and disease groups at p 3. A PLS-DA model revealed an excellent separation with 89.8% sensitivity and 97.2% specificity and the overall accuracy of the model was 92.2%. This metallomic study revealed that there is major difference in metallomic profiling of β-thalassemia patients specifically in Co, Mn, Ni, V and Ba, whereas the fold changes in Co, Mn, V and Ba were found to be greater than that in Fe, providing evidence that, in addition to Fe, other metals are also altered significantly and therefore chelation therapy for other metals may also needed in β-thalassemia patients.

    Palpation is widely used to assess muscular sensitivity in clinical settings but still remains a subjective evaluation. This cross-sectional study assessed a newly developed cross-friction algometry making palpation measurable. The objective was to investigate the reliability of pressure pain thresholds obtained using Cross-Friction Algometry (CFA-PPTs) measured at the level of Erector spinae and Gluteus maximus central muscle parts, and to compare the CFA-PPTs between patients with chronic nonspecific low back pain (nCLBP) and matching healthy subjects. Patients presenting nCLBP to GP's and send into a Pain Center and healthy subjects recruited via university ad valvas & flyers distribution. 30 patients with nCLBP were measured for cross-friction algometry. Other evaluations consisted of the Visual Analogue Scale (VAS) and the Oswestry Disability Index (ODI). The inter- and intra-reliability were tested and found to be sufficient. The mean CFA-PPT values of the Erector spinae at levels T8, T10, L1 & L3 and the Gluteus maximus of the nCLBP group were significantly lower (p ≤ 0.001) when compared to the CFA-PPT values of the healthy group. The greatest difference (-58%) was found at L1 Erector spinae level and at the superior part of the Gluteus maximus measuring point (-59%). Within the group of patients with nCLBP it was surprising to notice that there was no significant correlation between all the reference points measured using CFA-PPTs and the outcomes of the VAS and ODI scores. With the aid of CFA, the importance of local muscular disorder in the lumbar part of the Erector spinae and Gluteus maximus in patients with nCLBP is obviously demonstrated, but also reveals the very large inter-individual differences in muscular fibrosis sensitivity and/or pain behavior in daily life. This possibly re-opens the debate on which influences can be put forward as the most important: the central or the peripheral sensitization system. Copyright © 2015 Elsevier Ltd. All

    Body composition is a useful means for athletes' body composition assessment, relying on reference population data. This study aims at comparing body composition multifrequency impedance data of athletes and healthy adult populations. Differences were found in tissular, hydration and metabolic indices. They were significant, in the expected direction, but quite weak and additional data from reference technologies would set if specific equations are needed. The current ones are nevertheless suitable for reliable follow-up studies.

    Since serum can reflect human beings' physiological and pathological conditions, FTIR spectroscopy was used to compare gastric cancer patients' serum with healthy persons' serum in this study. The H2959/H2931, H1646/H1550, H1314/H1243, H1453/H1400 and H1080/H1550 ratios were calculated, among these ratios, the H2959/H2931 ratio might be a standard for distinguishing gastric cancer patients from healthy persons. Then curve fitting was processed using Gaussian curves in the 1140-1000 cm-1 region, and the result showed that the RNA/DNA ratios of gastric cancer patients' serum were obviously lower than those of healthy persons' serum. The results suggest that FTIR spectroscopy may be a potentially useful tool for diagnosis of gastric cancer.

    A controlled-release (CR) formulation of simvastatin was recently developed in Korea. The formulation is expected to yield a lower C(max) and similar AUC values compared with the immediate-release (IR) formulation. The goal of this study was to compare the pharmacokinetics of the new CR formulation and an IR formulation of simvastatin after single- and multiple-dose administration in healthy Korean subjects. This study was developed as part of a product development project at the request of the Korean regulatory agency. This was a randomized, open-label, parallelgroup, 2-part study. Eligible subjects were healthy male or female volunteers between the ages of 19 and 55 years and within 20% of their ideal weight. In part I, each subject received a single dose of the CR or IR formulation of simvastatin 40 mg orally (20 mg x 2 tablets) after fasting. In part II, each subject received the same dose of the CR or IR formulation for 8 consecutive days. Blood samples were obtained for 48 hours after the dose in part I and after the first and the last dose in part II. Pharmacokinetic parameters were determined for both simvastatin (the inactive prodrug) and simvastatin acid (the active moiety). An adverse event (AE) was defined as any unfavorable sign (including an abnormal laboratory finding) or symptom, regardless of whether it had a causal relationship with the study medication. Serious AEs were defined as any events that are considered life threatening, require hospitalization or prolongation of existing hospitalization, cause persistent or significant disability or incapacity, or result in congenital abnormality, birth defect, or death. AEs were determined based on patient interviews and physical examinations. Twenty-four healthy subjects (17 men, 7 women; mean [SD] age, 29 [7] years; age range, 22-50 years) were enrolled in part I, and 29 subjects (17 men, 12 women; mean age, 33 [9] years; age range, 19-55 years) were enrolled in part II. For simvastatin acid, C

(201Tl olfactory migration was also correlated with the volume of the olfactory bulb determined from MRI images, as well as with odor recognition thresholds measured by using T&T olfactometry. RESULTS: Nasal (201Tl migration to the olfactory bulb was significantly lower in the olfactory-impaired patients than in healthy volunteers. The migration of (201Tl to the olfactory bulb was significantly correlated with odor recognition thresholds obtained with T&T olfactometry and correlated with the volume of the olfactory bulb determined from MRI images when all subjects were included. CONCLUSIONS: Assessment of the (201Tl migration to the olfactory bulb was the new method for the evaluation of the olfactory nerve connectivity in patients with impaired olfaction.

    The eye lens is a transparent tissue constituted of tightly packed fiber cells. To maintain homeostasis and transparency of the lens, the circulation of water, ions and metabolites is required. Junctional microdomains connect the lens cells and ensure both tight cell-to-cell adhesion and intercellular flow of fluids through a microcirculation system. Here, we overview membrane morphology and tissue functional requirements of the mammalian lens. Atomic force microscopy (AFM) has opened up the possibility of visualizing the junctional microdomains at unprecedented submolecular resolution, revealing the supramolecular assembly of lens-specific aquaporin-0 (AQP0) and connexins (Cx). We compare the membrane protein assembly in healthy lenses with senile and diabetes-II cataract cases and novel data of the lens membranes from a congenital cataract. In the healthy case, AQP0s form characteristic square arrays confined by connexons. In the cases of senile and diabetes-II cataract patients, connexons were degraded, leading to malformation of AQP0 arrays and breakdown of the microcirculation system. In the congenital cataract, connexons are present, indicating probable non-membranous grounds for lens opacification. Further, we discuss the energetic aspects of the membrane organization in junctional microdomains. The AFM hence becomes a biomedical nano-imaging tool for the analysis of single-membrane protein supramolecular association in healthy and pathological membranes.

    Full Text Available Context There is a relative lack of studies about exhaled nitrite (NO2- concentrations in cirrhotic and transplanted patients. Objective Verify possible differences and correlations between the levels of NO2-, measured in plasma and exhaled breath condensate collected from patients with cirrhosis and liver transplant. Method Sixty adult male patients, aged between 27 and 67 years, were subdivided into three groups: a control group comprised of 15 healthy volunteers, a cirrhosis group composed of 15 volunteers, and a transplant group comprised of 30 volunteers. The NO2- concentrations were measured by chemiluminescence. Results 1 The analysis of plasma NO2- held among the three groups showed no statistical significance. 2 The comparison between cirrhotic and control groups, control and transplanted and cirrhotic and transplanted was not statistically significant. 3 The measurements performed on of NO2- exhaled breath condensate among the three groups showed no statistical difference. 4 When comparing the control group samples and cirrhotic, control and transplanted and cirrhotic and transplanted, there was no significant changes in the concentrations of NO2-. Conclusion No correlations were found between plasma and exhaled NO2-, suggesting that the exhaled NO2- is more reflective of local respiratory NO release than the systemic circulation.

    Sufficient sleep is essential for optimum cognitive and psychological functioning. Diminished sleep quality is associated with depression and anxiety, but the extent to which poor sleep quality uniquely impacts attention and executive functions independent of the effects of the common underlying features of depression and anxiety requires further exploration. Here 67 healthy young adults were given the Minnesota Multiphasic Personality Inventory, second edition (MMPI-2), the Pittsburgh Sleep Quality Index (PSQI), and tests of attention and executive functions. Similar to findings from a previous study with healthy community-based older adults (Nebes, Buysse, Halligan, Houck, & Monk, 2009), participants who reported poor sleep quality on the PSQI endorsed significantly greater scores on MMPI-2 Restructured Clinical scales related to depression and anxiety (Cohen's d = 0.77-1.05). In addition, PSQI component scores indexing poor sleep quality, duration, and medication use were associated with diminished attention and executive functions, even after controlling for emotional reactivity or demoralization (rs = 0.21-0.27). These results add to the concurrent validity of the PSQI, and provide further evidence for subtle cognitive decrements related to insufficient sleep even in healthy young adults. Future extension of these findings is necessary with larger samples and clinical comparison groups, and using objective indices of sleep dysfunction such as polysomnography.

    Full Text Available Background: Okinawa mozuku (Cladosiphon okamuranu is a type of edible seaweed of the family Chordariaceae that typically contains the polysaccharide fucoidan as a functional ingredient. In Okinawa, raw mozuku is eaten as vinegared mozuku together with vinegar or as tempura (deep-fried in batter. Polysaccharides such as fucoidan are generally known to regulate intestinal function, which is why we have used Okinawa mozuku to investigate this intestinal regulatory effect. Methods: The study was designed as a randomized, double-blind, parallel group study. Dried Okinawa mozuku powder at a dose of 2.4 g/day (1.0 g/day of fucoidan and a placebo not containing any dried Okinawa mozuku powder were each made into capsules and given to healthy men and women with infrequent weekly bowel movements (2–4 movements a week to ingest for eight weeks. We then investigated changes in the defecation situation, blood tests, and adverse events. Results: In the group that ingested the capsules containing dried Okinawa mozuku powder, the number of days with a bowel movement significantly increased compared with the placebo group after four weeks of ingestion (p < 0.05. Furthermore, after eight weeks of ingestion, the same increasing trend was seen compared with the placebo group (p = 0.0964. The volume of stool also increased significantly in the dried Okinawa mozuku powder group after eight weeks compared with the placebo group. In terms of blood tests and adverse events, no adverse events occurred that were the result of the test food. Conclusions: Ingestion of Okinawa mozuku was found to have a regulatory effect on intestinal function by promoting defecation in healthy individuals with a tendency for constipation. This demonstrated that Okinawa mozuku is a functional food capable of making defecation smoother and increasing the volume of stool.

    There is a need for more knowledge about how survivors of childhood cancer perceive their lives and what influence current health status has on their quality of life. The purpose was to describe this among a group of long-term survivors and among a comparison group. Telephone interviews were performed with a cohort of 246 long-term survivors and 296 randomly selected from the general population using the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW). The participants nominated the areas they considered to be most important in life and rated the current status of each area on a seven-point category scale. An overall individual index score was calculated as a measure of quality of life. Self-reported health status was assessed using the Short Form Health Survey (SF-36). Long-term survivors rated their overall quality of life and self-reported health status almost in parity with the comparison group. In both groups, family life, relations to other people, work and career, interests and leisure activities were the areas most frequently reported to influence quality of life. The survivors only differed from the comparison group on one of eight SF-36 scales reflecting problems with daily activities owing to physical health. Health status was not shown to have a major impact on overall quality of life, indicating that health and quality of life should be evaluated distinctively as different constructs. This should be taken in consideration in clinical care of children with childhood cancer and long-term survivors. (c) 2010 Wiley-Liss, Inc.

    Full Text Available Objective: This study is carried on to compare personality traits, coping strategies, and attributional styles of opiate-dependent patients and healthy people. Materials & Methods: In this cross-sctional and comparative research, three scales Eysenk Personality Questionaire RS (EPQ-RS, Coping Response Inventory (CRI, and Attributional Style Questionnaire (ASQ are used to measure the mentioned variables on 158 people (78 opiate-dependent patient and 80 healthy people selected by accessible sampling method. Research data were examined on the basis of T-test for independent groups and logistic regression. Results: Results of T-test showed that there were significant differences between healthy and patient group in Coping Response Inventory and Personality Traits Subscale(except Lying subscale and attribution styles for negative events (P<0.001. Logistic regression results showed that all of these variables which entered in model, are able to predict distinction one group from other patient group and healthy one in a meaningful way(P<0.001. Conclusion: opiate-dependent patients when they face problems significantly use problem-solving strategies, social support seeking, and cognitive evaluation significantly less than healthy group and use physical inhibition and emotional inhibition significantly more than the healthy group. Also, drug-dependent patients in terms of tendency to Neuroticism, psychoticism and introversion were significantly higher than the healthy group, and they had more pessimistic attributional style towards negative events. On the other hand it became apparent that some aspects of personality characteristics, coping strategies, and attributional style considerably were able to distinguish healthy people from opiate-dependent patients.

    Full Text Available Ketosis is a metabolic disorder closely associated with liver lipidosis. Numerous tests have been developed to detect hepatic dysfunction in dairy cows. Bromosulfophthalein (BSP clearance is established as a sensitive index of hepatic function. The objective of this study was to examine the difference of biliary excretion of BSP between ketotic and healthy Holstein cows and to correlate this excretion with other indicators of liver dysfunction. Twenty puerperal Holstein cows divided in two groups (10 cows each were involved in the study. The first group included healthy and the second group ketotic cows. Blood samples were taken 10 days after parturition. Concentrations of total protein, albumin, total bilirubin, Ca, P, total lipids, urea and glucose were determined. Immediately after blood sampling, BSP test was performed. Blood samples were taken 5 and 45 minutes after injection, and the percentage of retained pigment in the sample obtained at minute 45 was calculated. Blood albumin and glucose concentrations were significantly higher in healthy then ketotic cows. Total bilirubin concentration was significantly higher in ketotic than healthy cows. BSP excretion was significantly higher in ketotic compared to healthy cows. There was a significant positive correlation between BSP values and total bilirubin concentrartions in both healthy and ketotic cows and a significant negative correlation between BSP values and glucose concentrartions in both healthy and ketotic cows. In conclusion, biliary clearance of BSP may be used as a reliable method for the detection of hepatic dysfunction associated with clinical symptoms of ketosis in dairy cows.

    Most of the studies focusing on the effect of stress on false memories by using psychosocial and physiological stressors yielded diverse results. In the present study, we systematically tested the effect of exogenous hydrocortisone using a false memory paradigm. In this placebo-controlled study, 37 healthy men and 38 healthy women (mean age 24.59 years) received either 10 mg of hydrocortisone or placebo 75 min before using the false memory, that is, Deese-Roediger-McDermott (DRM), paradigm. We used emotionally charged and neutral DRM-based word lists to look for false recognition rates in comparison to true recognition rates. Overall, we expected an increase in false memory after hydrocortisone compared to placebo. No differences between the cortisol and the placebo group were revealed for false and for true recognition performance. In general, false recognition rates were lower compared to true recognition rates. Furthermore, we found a valence effect (neutral, positive, negative, disgust word stimuli), indicating higher rates of true and false recognition for emotional compared to neutral words. We further found an interaction effect between sex and recognition. Post hoc t tests showed that for true recognition women showed a significantly better memory performance than men, independent of treatment. This study does not support the hypothesis that cortisol decreases the ability to distinguish between old versus novel words in young healthy individuals. However, sex and emotional valence of word stimuli appear to be important moderators. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Despite the widely accepted view that the cognitive function is involved in characteristic tree-drawing in patients with SZ, no study has psychophysiologically examined it. The present study aimed to investigate the involvement of cognitive function during tree-drawing in patients with SZ. For that purpose, we evaluated the brain function in patients with SZ during a tree-drawing task by using near-infrared spectroscopy (NIRS and compared them with those in healthy controls. Patients and methods: The subjects were 28 healthy controls and 28 patients with SZ. Changes in the oxygenated hemoglobin ([oxy-Hb] concentration in both the groups during the task of drawing a tree imagined freely (free-drawing task and the task of copying an illustration of a tree (copying task were measured by using NIRS. Results: Because of the difference between the task conditions, [oxy-Hb] levels in controls during the free-drawing task were higher than that during the copying task at the bilateral frontal pole regions and left inferior frontal region. Because of the difference between the groups, [oxy-Hb] levels at the left middle frontal region, bilateral inferior frontal regions, bilateral inferior parietal regions, and left superior temporal region during the free-drawing task in patients were

    The purpose of this study was to evaluate the prevalence of sarcopenia in a cohort of healthy community-dwelling elderly in an urban area in Barcelona (Spain) for native benchmarks and compare them with those published in other geographical areas. We prospectively evaluated a series of 200 healthy elderly in the community with preserved functional capacity and absence of cognitive impairment. We performed a comprehensive geriatric assessment and determined anthropometric data, muscle mass (MM) and the muscle mass index (MMI). Assessment of muscle mass was performed by bioelectrical impedance analysis (BIA). The cut-off point for defining sarcopenia MMI was established as less than 2 SD of the mean of a reference group comprising 220 healthy volunteers (20-42 years) in the same area. Results were compared with studies undertaken in the USA, France and Taiwan. The cut-off points obtained were 8.31 Kg/m(2) for men and 6.68 Kg/m2 for women, being similar to those observed in France and Taiwan but different from the USA. The prevalence of sarcopenia observed was 33% for elderly women and 10% for males. On comparison of the prevalence of sarcopenia in the four populations, we observed some differences, particularly in males. We have defined reference values for sarcopenia, determined by BIA, in our setting. We also observed a remarkable prevalence of sarcopenia in the healthy elderly community, especially in females, showing some differences from those in other geographical regions.

    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.

    Variations between countries in leisure-time physical activity (LTPA) can be used to test the convergence thesis, which expects that ethnic minority groups change towards the LTPA levels of the native population of host countries. The aim of this study was to test whether similar differences in LTPA between the native populations of England and the Netherlands are also observed among the Indian and African descent groups living in these countries. We used English and Dutch population-based health surveys that included participants aged 35-60 years of European (n(english) = 14,723, n(dutch) = 567), Indian (n(english) = 1264, n(dutch) = 370) and African-Caribbean (n(english) = 1112, n(dutch) = 689) descent. Levels of LTPA (30-minute walking, any reported cycling, gardening, dancing and playing sports) were estimated with age-sex-standardized prevalence rates. Comparisons among groups were made using adjusted Prevalence Ratios (PRs). Within both countries and compared with the European group, Indian and African groups had lower levels of gardening and cycling, whereas the African groups had higher levels of dancing. Between countries, among the European groups, the Netherlands showed higher prevalence of cycling than England, PR = 2.26 (95% CI: 2.06-2.48), and this was 2.85 (1.94-4.19) among Indian descent, and 2.77 (2.05-3.73) among African descent. For playing sports, this was PR = 1.30 (1.23-1.38), 1.43 (1.24-1.66) and 1.22 (1.10-1.34), whereas for gardening this was PR = 0.71 (0.65-0.78), 0.65 (0.52-0.81) and 0.75 (0.62-0.90), respectively. Walking and dancing showed inconsistent differences between the countries and ethnic groups. This cross-national comparison supports the expectation that LTPA of Indian and African descent groups converge towards the national levels of England and the Netherlands respectively.

    Full Text Available The measurement of serum thromboxane B2 (TXB2 production by platelets is a specific test for assessment of platelet cyclooxygenase (COX-1 activity following administration of non-steroidal anti-inflammatory drugs (NSAIDs. The aim of this study was to investigate the influence of sample incubation at 37 °C for one hour on serum TXB2 concentration in comparison with incubation at room temperature. A total of 54 blood samples for serum TXB2 measurements were collected from six healthy beagle dogs into two separate serum tubes. While one group of tubes was incubated in a 37 °C water bath, the second group of tubes was left to coagulate at room temperature, both for one hour. Serum TXB2 concentrations were measured by ELISA. The mean concentration (± SD of serum TXB2 in the group of samples that were incubated at 37 °C was significantly (P 2 concentration in healthy beagle dogs and demonstrate that validated methods for assessment of COX-1 activity by measurement of serum TXB2 should be used in order to make results more reliable and comparable between different studies. The results of this study might be of great help in planning NSAID studies in dogs by providing the information that TXB2 generation by platelets is influenced profoundly by incubation temperature.

    Utah women from some cultural minority groups have higher overweight/obesity rates than the overall population. We utilized a gender-based mixed methods approach to learn about the underlying social, cultural and gender issues that contribute to the increased obesity risk among these women and to inform intervention development. A literature review and analysis of Utah's Behavioral Risk Factor Surveillance System data informed the development of a focus group guide. Focus groups were conducted with five groups of women: African immigrants from Burundi and Rwanda, African Americans, American Indians/Alaskan Natives, Hispanics/Latinas, and Pacific Islanders. Six common themes emerged: (1) health is multidimensional and interventions must address health in this manner; (2) limited resources and time influence health behaviors; (3) norms about healthy weight vary, with certain communities showing more preference to heavier women; (4) women and men have important but different influences on healthy lifestyle practices within households; (5) women have an influential role on the health of families; and (6) opportunities exist within each group to improve health. Seeking insights from these five groups of women helped to identify common and distinct cultural and gender themes related to obesity, which can be used to help elucidate core obesity determinants.

    Full Text Available BACKGROUND: Cardiovascular diseases (CVD are a set of metabolic disorders affecting heart and blood vessels. Green tea and sour tea (Hibiscus sabdariffa L. have attracted significant attention recently due to their high popularity, nutrient profile and therapeutic effects. The aim of the present study was to compare the effects of green tea and sour tea supplementation on blood pressure and lipid profile in healthy adult men. METHODS: This randomized, double-blind, placebo-controlled trial included 54 healthy adult men. The participants were randomly assigned to two intervention groups receiving 450 mg green tea or sour tea and one placebo group which consumed 450 mg placebo (maltodextrin for 6 weeks. Blood pressure, lipid profile, dietary intake and physical activity were measured pre- and post-intervention and compared. RESULTS: After 6 weeks of intervention, sour tea supplementation led to a significant decrease in systolic blood pressure (SBP compared with the placebo group. However, we faild to find any significant difference in SBP between green tea and control groups. Also, no significant changes were observed in diastolic blood pressure (DBP and lipid profile between the three groups. In comparison with baseline, there was a significant increase in the mean level of serum high-density lipoprotein cholesterol (HDL-C in green tea and sour tea groups. Also, the interventions resulted in significant decrease in the mean levels of serum total cholesterol (TC and low-density lipoprotein cholesterol (LDL-C and DBP in the sour tea group compared with the pre-intervention value. CONCLUSION: On the basis of our findings, sour tea supplementation led to decreased SBP in healthy men compared with the placebo, but there was no significant difference between their effects on DBP and lipid profile.

    Full Text Available Objectives: The aim of current study was the evaluation and comparison of compatibility and marital satisfaction between handicapped couples and healthy ones. Methods: In this study, 50 handicapped couples and 50 healthy couples were examined with Enrich’s marital satisfaction questionnaire and Bell’s adjustment questionnaire. The data were analyzed, using SPSS 15, correlation tests and ANOVA. Results: The results showed that there was no significant difference between handicapped and healthy couples in compatibility and marital satisfaction. Discussion: It is concluded that people who were handicapped before their marriage and those who decided to marry them were suitably aware of the issue, therefore accepting a handicapped person was not so hard. What is important in marital compatibility is accepting a partner.

    In the context of food, convenience is generally associated with less healthy foods. Given the reality of present-biased preferences, if convenience was associated with healthier foods and less healthy foods were less convenient, people would likely consume healthier foods. This study examines the application of this principle in a school lunchroom where healthier foods were made more convenient relative to less healthy foods. One of two lunch lines in a cafeteria was arranged so as to display only healthier foods and flavored milk. Trained field researchers collected purchase and consumption data before and after the conversion. Mean comparisons were used to identify differences in selection and consumption of healthier foods, less healthy foods and chocolate milk. Sales of healthier foods increased by 18% and grams of less healthy foods consumed decreased by nearly 28%. Also, healthier foods' share of total consumption increased from 33 to 36%. Lastly, we find that students increased their consumption of flavored milk, but flavored milk's share of total consumption did not increase. In a school lunchroom, a convenience line that offered only healthier food options nudged students to consume fewer unhealthy foods. This result has key implications for encouraging healthy behavior in public schools nation wide, cafeterias and other food establishments.

    A compendium of all the volatile organic compounds (VOCs) emanating from the human body (the volatolome) is for the first time reported. 1840 VOCs have been assigned from breath (872), saliva (359), blood (154), milk (256), skin secretions (532) urine (279), and faeces (381) in apparently healthy individuals. Compounds were assigned CAS registry numbers and named according to a common convention where possible. The compounds have been grouped into tables according to their chemical class or functionality to permit easy comparison. Some clear differences are observed, for instance, a lack of esters in urine with a high number in faeces. Careful use of the database is needed. The numbers may not be a true reflection of the actual VOCs present from each bodily excretion. The lack of a compound could be due to the techniques used or reflect the intensity of effort e.g. there are few publications on VOCs from blood compared to a large number on VOCs in breath. The large number of volatiles reported from skin is partly due to the methodologies used, e.g. collecting excretions on glass beads and then heating to desorb VOCs. All compounds have been included as reported (unless there was a clear discrepancy between name and chemical structure), but there may be some mistaken assignations arising from the original publications, particularly for isomers. It is the authors' intention that this database will not only be a useful database of VOCs listed in the literature, but will stimulate further study of VOCs from healthy individuals. Establishing a list of volatiles emanating from healthy individuals and increased understanding of VOC metabolic pathways is an important step for differentiating between diseases using VOCs.

    Suicidal behavior is heritable, with the transmission of risk being related to the transmission of vulnerability traits. Previous studies suggest that risky decision-making may be an endophenotype of suicide. Here, we aimed at investigating brain processing of decision-making in relatives of suicide completers in order to shed light on heritable mechanisms of suicidal vulnerability. Seventeen healthy first-degree biological relatives of suicide completers with no personal history of suicidal behavior, 16 relatives of depressed patients without any personal or family history of suicidal behavior, and 19 healthy controls were recruited. Functional 3 T magnetic resonance imaging scans were acquired while participants underwent the Iowa Gambling Task, an economic decision-making test. Whole-brain analyses contrasting activations during risky vs safe choices were conducted with AFNI and FSL. Individuals with a family history of suicide in comparison to control groups showed altered contrasts in left medial orbitofrontal cortex, and right dorsomedial prefrontal cortex. This pattern was different from the neural basis of familial depression. Moreover, controls in comparison to relatives showed increased contrast in several regions including the post-central gyrus, posterior cingulate and parietal cortices, and cerebellum (culmen) in familial suicide; and inferior parietal, temporal, occipital, anteromedial and dorsolateral prefrontal cortices, and cerebellum (vermis) in familial depression. These findings most likely represent a complex combination of vulnerability and protective mechanisms in relatives. They also support a significant role for deficient risk processing, and ventral and dorsal prefrontal cortex functioning in the suicidal diathesis.

    Human cognitive functioning can be assessed using different methods of testing. Age, level of education, and gender may influence the results of cognitive tests. The well-known Trail Making Test (TMT), which is often used to measure the frontal lobe function, and the experimental test of Interval Timing (IT) were compared. The methods used in IT included reproduction of auditory and visual stimuli, with the subsequent production of the time intervals of 1-, 2-, 5-, and 7-seconds durations with no pattern. Subjects included 64 healthy adult volunteers aged 18-63 (33 women, 31 men). Comparisons were made based on age, education, and gender. TMT was performed quickly and was influenced by age, education, and gender. All reproduced visual and produced intervals were shortened and the reproduction of auditory stimuli was more complex. Age, education, and gender have more pronounced impact on the cognitive test than on the interval timing test. The reproduction of the short auditory stimuli was more accurate in comparison to other modalities used in the IT test. The interval timing, when compared to the TMT, offers an interesting possibility of testing. Further studies are necessary to confirm the initial observation.

    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 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.

    Full Text Available Context: 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. Objective: To investigate the influence of osteopathic manipulative treatment (OMT on ANS activity through changes of High Frequency, a heart rate variability index indicating the parasympathetic activity, in healthy subjects, compared with sham therapy and control group.Methods: 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, both smokers and non-smokers and not on medications. At enrollment subjects were randomized in 3 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.Main Outcomes Measures: HRV was calculated from electrocardiography before, during and after the intervention, for a total amount time of 25 minutes.Results: OMT engendered a statistically significant increase of parasympathetic activity, as shown by High Frequency rate (p<0.001, and decrease of sympathetic activity, as revealed by Low Frequency rate (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. Conclusions: Findings suggested that OMT can influence ANS activity increasing parasympathetic function and decreasing sympathetic activity, compared to sham therapy and control group.

    Food high in energy but low in nutritional value is an important contributor to several serious illnesses, and one type of food that is particularly high in energy but low in nutrition is food consumed away from home. In this paper, we examine the demand and willingness to pay for healthy, Keyhole-labelled meals. A Keyhole-labelled meal is particularly low in energy, fat, sugar and salt, but particularly high in fibre. The results suggest that to get the majority of individuals to choose the healthy option regularly it would be necessary to alter the relative price between healthy and less healthy meals. Generally groups of individuals with a poor nutritional intake require a larger compensation (subsidy) before they choose the healthy alternative. About one third of respondents would choose the healthy option regularly if the prices for a healthy and less healthy meal were the same. In particular groups of individuals who already have a relatively good nutritional intake would select the healthy option. Groups with a generally poor nutritional intake (men and individuals with lower education and lower income) would gain health benefits from a subsidy of Keyhole-labelled meals.

    A flipped classroom approach has been implemented in an undergraduate fluid mechanics course. Students watch short on-line videos before class, participate in active in-class problem solving (in dyads), and complete individualized on-line quizzes weekly. In-class activities are designed to achieve a trifecta of: 1. developing problem solving skills, 2. learning subject content, and 3. developing inquiry skills. The instructor and assistants provide critical ``just-in-time tutoring'' during the in-class problem solving sessions. Comparisons are made with a simultaneous section offered in a traditional mode by a different instructor. Regression analysis was used to control for differences among students and to quantify the effect of the flipped fluid mechanics course. The dependent variable was the students' combined final examination and post-concept inventory scores and the independent variables were pre-concept inventory score, gender, major, course section, and (incoming) GPA. The R-square equaled 0.45 indicating that the included variables explain 45% of the variation in the dependent variable. The regression results indicated that if the student took the flipped fluid mechanics course, the dependent variable (i.e., combined final exam and post-concept inventory scores) was raised by 7.25 points. Interestingly, the comparison group reported significantly more often that their course emphasized memorization than did the flipped classroom group.

    Sodium and chlorine values are reported in μ/g, as determined by neutron activation analysis in washed hair and nails from healthy and cystic fibrosis children. The values thus determined in cystic fibrosis tended to be higher than those in controls, however statistical differences were not significant (p>0.01). Additional experiments were carried out for comparison between washed and unwashed samples of the cystic fibrosis and control group and only the differences between washed and unwashed cystic fibrosis nails were significant (p<0.01) in both sodium and chlorine values. Analysis of a standard reference milk sample, A-11 from IAEA, for the elements mentioned above gave a good agreement with the certified values. (author) 24 refs.; 6 figs.; 2 tabs

    Fifteen young adult dogs were divided into three groups representing 0, 7- and 21-day healing periods. Randomly selected cuspid teeth were used to compare cord gingival displacement and gingitage techniques for subgingival tooth preparation and impression making. Clinical and histologic measurements were used as a basis for comparison. Results indicate that (1) the experimental teeth were clinically healthy at the beginning of the experiment, (2) clinical health of the gingival tissues was controlled throughout the course of the experiment, and (3) within this experimental setting, there was no significant difference between the cord gingival displacement technique and the gingitage technique.

    Cheyne-Stokes respiration (CSR) has been investigated primarily in outpatients with heart failure. In this study we compare CSR and periodic breathing (PB) between healthy and cardiac groups. We compared CSR and PB, measured during 24 hr of continuous 12-lead electrocardiographic (ECG) Holter recording, in a group of 90 hospitalized patients presenting to the emergency department with symptoms suggestive of acute coronary syndrome (ACS) to a group of 100 healthy ambulatory participants. We also examined CSR and PB in the 90 patients presenting with ACS symptoms, divided into a group of 39 (43%) with confirmed ACS, and 51 (57%) with a cardiac diagnosis but non-ACS. SuperECG software was used to derive respiration and then calculate CSR and PB episodes from the ECG Holter data. Regression analyses were used to analyze the data. We hypothesized SuperECG software would differentiate between the groups by detecting less CSR and PB in the healthy group than the group of patients presenting to the emergency department with ACS symptoms. Hospitalized patients with suspected ACS had 7.3 times more CSR episodes and 1.6 times more PB episodes than healthy ambulatory participants. Patients with confirmed ACS had 6.0 times more CSR episodes and 1.3 times more PB episodes than cardiac non-ACS patients. Continuous 12-lead ECG derived CSR and PB appear to differentiate between healthy participants and hospitalized patients. © 2017 Wiley Periodicals, Inc.

    Background. A multidisciplinary approach seems to be effective in creating healthy habits in children. The aim of this study was to evaluate the efficacy of three 5-month combined physical education (PE) and nutritional interventions on body composition, physical activity (PA) level, sedentary time and eating habits of schoolchildren. Methods. Anthropometric data, weekly PA level, sedentary time and eating habits of 230 healthy students were analysed using a repeated-measures ANOVA with Group (experimental group 1 vs experimental group 2 vs control group), Adiposity Status (under fat vs normal fat vs obese), and Time (pre vs post) as factors. Results. Body fat mass percentage increased after intervention (18.92 ± 8.61% vs 19.40 ± 8.51%) in all groups. The weekly PA level significantly increased after intervention in both experimental groups. Sedentary time significantly decreased after the intervention period (565.70 ± 252.93 vs 492.10 ± 230.97 min/week, p healthy habits through life.

  14. Can We Achieve Intuitive Prosthetic Elbow Control Based on Healthy Upper Limb Motor Strategies?

    Full Text Available Most transhumeral amputees report that their prosthetic device lacks functionality, citing the control strategy as a major limitation. Indeed, they are required to control several degrees of freedom with muscle groups primarily used for elbow actuation. As a result, most of them choose to have a one-degree-of-freedom myoelectric hand for grasping objects, a myoelectric wrist for pronation/supination, and a body-powered elbow. Unlike healthy upper limb movements, the prosthetic elbow joint angle, adjusted prior to the motion, is not involved in the overall upper limb movements, causing the rest of the body to compensate for the lack of mobility of the prosthesis. A promising solution to improve upper limb prosthesis control exploits the residual limb mobility: like in healthy movements, shoulder and prosthetic elbow motions are coupled using inter-joint coordination models. The present study aims to test this approach. A transhumeral amputated individual used a prosthesis with a residual limb motion-driven elbow to point at targets. The prosthetic elbow motion was derived from IMU-based shoulder measurements and a generic model of inter-joint coordinations built from healthy individuals data. For comparison, the participant also performed the task while the prosthetic elbow was implemented with his own myoelectric control strategy. The results show that although the transhumeral amputated participant achieved the pointing task with a better precision when the elbow was myoelectrically-controlled, he had to develop large compensatory trunk movements. Automatic elbow control reduced trunk displacements, and enabled a more natural body behavior with synchronous shoulder and elbow motions. However, due to socket impairments, the residual limb amplitudes were not as large as those of healthy shoulder movements. Therefore, this work also investigates if a control strategy whereby prosthetic joints are automatized according to healthy individuals

    L-ornithine is a non-essential, non-protein amino acid. Although L-ornithine is contained in various foods, the amount is usually small.Recently, studies have shown that orally administered L-ornithine reduced the stress response in animals.From these findings, we speculated that L-ornithine may play a role in the relieve of stress and improve sleep and fatigue symptoms in humans. Through a randomised, double-blind, placebo-controlled clinical study, we asked if L-ornithine could be beneficial to stress and sleep in healthy workers. Fifty-two apparently healthy Japanese adults who had previously felt slight stress as well as fatigue were recruited to be study participants and were randomly divided into either the L-ornithine (400 mg/day) or placebo group. They orally consumed the respective test substance every day for 8 weeks. Serum was collected for the assessment of cortisol and dehydroepiandrosterone-sulphate (DHEA-S). Perceived mood and quality of sleep were measured by the Profile of Mood States (POMS), Athens Insomnia Scale (AIS), and Ogri-Shirakawa-Azumi sleep inventory MA version (OSA-MA). Serum cortisol levels and the cortisol/DHEA-S ratio were significantly decreased in the L-ornithine group in comparison with the placebo group. Also, anger was reduced and perceived sleep quality was improved in the L-ornithine group. L-ornithine supplementation has the potential to relieve stress and improve sleep quality related to fatigue, both objectively and subjectively.

    As in many other countries, Australian consumers have recently had to accommodate increases in costs of basic food, and during the financial year 2007-2008 overall food prices rose by nearly 4%. Food costs are mediating factors in food choice, especially for low-income groups, where food security is often tenuous. There are reports that rural populations may have higher levels of food insecurity, although the evidence is often contradictory. To assess cost and affordability of food in rural areas this study used the Healthy Food Basket (HFB) methodology, which has been applied in a number of settings. The HFBs were costed at supermarkets and stores in different locations with different degrees of rurality. Compared with metropolitan areas, healthy food is more expensive in rural areas; costs are even higher in more remote areas. The overall affordability of HFB in rural areas was not significantly different from metro areas. The main difference concerned low socio-economic status (SES) groups, where the proportion of household income spent on the HFB was three times that of higher SES groups. The unaffordability of healthy food, or 'food stress' in low SES groups is a concern, especially when this group carries the greatest burden of diet-related disease. Findings suggest that there is a need to consider both rurality and SES when developing policy responses to decrease the cost and increase the affordability of healthy foods in rural and remote areas.

    Studies have shown that Allium sativum L. (AS) protects amyloid-beta peptide-induced apoptosis, prevents oxidative insults to neurons and synapses, and thus prevent Alzheimer's disease progression in experimental animals. However, there is no experimental evidence in human regarding its putative role in memory and cognition. We have studied the effect of AS consumption by healthy human volunteers on visual memory, verbal memory, attention, and executive function in comparison to control subjects taking placebo. The study was conducted over five weeks and twenty volunteers of both genders were recruited and divided randomly into two groups: A (AS) and B (placebo). Both groups participated in the 6 computerized neuropsychological tests of the Cambridge Neuropsychological Test Automated Battery (CANTAB) twice: at the beginning and after five weeks of the study. We found statistically significant difference (p 0.05) beneficial effects on verbal memory and executive function within a short period of time among the volunteers. Study for a longer period of time with patients suffering from neurodegenerative diseases might yield more relevant results regarding the potential therapeutic role of AS. PMID:26351508

    The skin is the body's largest organ that hosts heterogeneous inhabitants. Until now, the diversity of the cutaneous microbiome was mainly investigated for bacteria and there is a little information about the skin fungal flora. Also, among skin fungal flora, Candida is found as a main member whose distribution is affected by sex, age, climate. In this study, differences in Candida community structure associated with 9 different skin sites of 238 healthy people during 10 months from July to March 2016, are described. These subjects were divided by age into 4 groups: infants, children, adults and geriatrics. The collected samples were examined by culture on Sabouraud Chloramphenicol Agar and CHROM-agar Candida. For precise identification of species ITS1-5. 8S-ITS2 rDNA regions were sequenced where needed. The frequency of Candida species was significantly different between age groups. The most Candida isolations were related to the elderly age group and the fewest in the infants. C. parapsilosis virtually, was the predominant isolated species in all age groups. This study showed no statistically significant effect of the subject's sex on Candida population resident on human skin surface. Copyright © 2017. Published by Elsevier Masson SAS.

    There is increasing interest in using social media sites such as Facebook to deliver health interventions so as to expose people to content while they are engaging in their usual social media habit. This formative intervention development study is novel in describing a preliminary test of using the secret group feature of Facebook to deliver a behavioral intervention targeting users of indoor tanning beds to reduce their risk of skin cancer. Intervention content was designed to challenge body image-related constructs associated with indoor tanning through the use of dissonance-inducing content. To evaluate engagement with and acceptability of using a secret Facebook group to deliver a healthy body image intervention to young women engaged in indoor tanning. Seventeen young women completed a baseline survey and joined a secret Facebook group with intervention content delivered via daily posts for 4 weeks. Engagement data was extracted and acceptability was measured via a follow-up survey. The study had a high retention rate (94%, [16/17]). On average, posts were viewed by 91% of participants, liked by 35%, and commented on by 26%. The average comment rate was highest (65%) for posts that elicited comments by directly posing questions or discussion topics to the group. Average intervention acceptability ratings were highly positive and participants reported feeling connected to the group and its topic. Average rates of past 1-month indoor tanning reported following the intervention were lower than the baseline rate (P=.08, Cohen d=0.47). This study is novel in demonstrating participant engagement with and acceptability of using Facebook secret groups to deliver a dissonance-inducing intervention approach that utilizes group-based discussions related to body image. The study is also unique within the field of skin cancer prevention by demonstrating the potential value of delivering an indoor tanning intervention within an interactive social media format.

    Full Text Available Escherichia coli is a normal inhabitant of the gastrointestinal tract of vertebrates. Certain Escherichia coli strains have been associated with neonatal diarrhoea in ruminants. These strains can be assigned to one of the four main phylogenetic groups, A, B1, B2 and D. Several studies have shown the rela-tionship between phylogeny and pathogenicity of E. coli, a great deal can be obtained by determining the phylogroup of unknown E. coli strains. In this study, we aimed to evaluate the influence of diar-rhoea on the genetic composition of E. coli populations isolated from calves. A total of 80 Es-cherichia coli isolates were obtained from healthy and diarrhoeic calves. Phylogenetic grouping was done based on the Clermont triplex PCR method using primers targeted at three genetic markers, chuA, yjaA and TspE4.C2. According to our results, phylogenetic group A strains was the most prevalent in both healthy (37.5% and diarrhoeic calves (55%. Group B1 contained 27.5% of isolates in healthy calves, followed by group B2 (17.5%, and group D (7.5%. Also, four isolates from healthy calves were not included in the major phylogenetic groups or subgroups. A total of 14% and 4% of isolates from diarrhoeic calves beloned to phylogroups B2 and D respectively. Although no isolate from diarrhoeic calves was found to belong to group B1, there was no significant difference between healthy and diarrhoeic calves for other phylogroups. There was not a dramatic shift in E. coli phylogroup/subgroup due to occurrence of diarrhoea in calves, except for phylogroup B1 which was higher in healthy calves. This can be due to the difference in secretions of digestive system in diarrhoeic calves which can prevent the conditions for instability of Escherichia coli isolates of phy-logroup B1. The majority of isolates from both healthy and diarrhoeic calves belonged to non-pathogenic phylogentic group A and B1.

Blood samples were taken in both groups of examined cows at the following time intervals: just before (time 0 and 8, 30, 60, 120, 180, 240 and 480 min after the intravenous infusion of 1.84 mol l-1 solution of propionate in the amount of 1 ml kg-1 of body weight. Glucose and insulin blood serum values in both groups of cows increased significantly within 120 min of the experiment (p p p p < 0.05 in blood value of inorganic phosphorus in ketotic cows in comparison with healthy ones. This is linked with the active entry of glucose into glucolytic pathway of peripheral tissues. It can thus be concluded that there is a higher degree of blood glucose utilization by peripheral tissues in ketotic cows.

    Full Text Available Fifteen broiler chickens (COBB 400 of 42 days of age weighing 1.8 to 2.0 kg were equally divided into 3 groups, each consisting of 5 birds. Hepatopathy was induced by oral administration of paracetamol while nephropathy was induced by intravenous administration of uranyl nitrate. Kinetic study was investigated in healthy, hepatopathic and nephropathic birds following single oral administration of amoxicillin at 40 mg kg-1. Blood samples were collected at different time schedule. Plasma concentrations of amoxicillin in healthy, hepatopathic and nephropathic birds were 41.90 ± 5.59, 9.93 ± 0.76 and 38.75 ± 6.08 µg ml-1, respectively at 1 hr; 15.34 ± 1.99, 18.57 ± 1.66 and 67.40 ± 2.62 µg ml-1, respectively at 4 hr and 2.03 ± 0.28, 15.54 ± 0.82 and 30.63 ± 1.58 µg ml-1, respectively at 24 hr. Maximum plasma concentration was detected at 1 hr in healthy birds (41.90 ± 5.59 µg ml-1 , at 8 hr in hepatopathic birds (23.51 ± 1.64 µg ml-1 and at 4 hr in nephropathic birds (67.40 ± 2.62 µg ml-1. The drug could not be detected in plasma beyond 24 hr in healthy, 72 hr in both hepatopathic and nephropathic birds. The concentration of amoxicillin was significantly (P < 0.01 higher in most of the samples of hepatopathic and nephropathic birds compared to healthy birds. Significant higher values (P < 0.01 of t1/2 K, AUC, and MRT and lower values of K and ClB in the hepatopathic and nephropathic birds in comparison to healthy birds were observed.

    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 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

    To investigate the relieving effects of hot spring balneotherapy on mental stress, sleep disorder, general health problems, and women's health problems in sub-healthy people, we recruited 500 volunteers in sub-health in Chongqing, and 362 volunteers completed the project, including 223 in the intervention group and 139 in the control group. The intervention group underwent hot spring balneotherapy for 5 months, while the control group did not. The two groups took questionnaire investigation (general data, mental stress, emotional status, sleep quality, general health problems, as well as some women's health problems) and physical examination (height, weight, waist circumference, blood pressure, blood lipid, blood sugar) 5 months before and after the intervention, respectively. After intervention, sleep disorder (difficulty in falling asleep ( P = 0.017); dreaminess, nightmare suffering, and restless sleep ( P = 0.013); easy awakening ( P = 0.003) and difficulty in falling into sleep again after awakening( P = 0.016); and mental stress ( P = 0.031) and problems of general health (head pain ( P = 0.026), joint pain( P = 0.009), leg or foot cramps ( P = 0.001), blurred vision ( P = 0.009)) were relieved significantly in the intervention group, as compared with the control group. While other indicators (fatigue, eye tiredness, limb numbness, constipation, skin allergy) and women's health problems (breast distending pain; dysmenorrhea, irregular menstruation) were relieved significantly in the self-comparison of the intervention group before and after intervention ( P 0.05). All indications (except bad mood, low mood, and worry or irritability) in the intervention group significantly improved, with effect size from 0.096 to 1.302. Multiple logistic regression analysis showed that the frequency, length, and location of balneotherapy in the intervention group were the factors influencing emotion, sleep, and health condition ( P Physical examination found that waist

    To investigate the direct and indirect cost differences associated with eating a 'healthy' or 'unhealthy' diet. Analysis of data from a baseline postal questionnaire for the UK Women's Cohort Study, including a detailed food frequency questionnaire (FFQ), supplemented by a telephone interview on a sub-sample. The first 15,191 women who responded to the questionnaire, aged 35-69 years with similar numbers of meat eaters, fish eaters and vegetarians. A healthy diet indicator (hdi), with values from 0 (lowest) to 8 (highest) was developed based on the WHO dietary recommendations. Direct monetary cost of the diet was calculated using prices from the 1995 National Food Survey and the Tesco home shopping catalogue. Women in the healthy diet group were almost four times as likely to be vegetarian and have a higher educational level. For direct costs, the difference between the most extreme hdi groups was 1.48 day-1 (equivalent to 540 year-1), with fruit and vegetable expenditure being the main items making a healthy diet more expensive. Forty-nine per cent of the food budget was spent on fruit and vegetables in hdi group 8 compared to 29% in hdi group 0. Interestingly, 52% of those questioned in both extreme hdi groups did not think that it was difficult to eat healthily. To achieve a particularly healthy diet independent predictive factors were spending more money, being a vegetarian, having a higher energy intake, having a lower body mass index (BMI) and being older.

    The aim of the study was to explore community-dwelling stroke patients' perceived barriers to healthy-lifestyle participation for secondary disease prevention, as well as their preferred means for risk-reduction information dissemination and motivators to participation in healthy-lifestyle interventions. Four focus groups (5-6 stroke survivors per group) were defined from community support groups. Key questions addressed barriers to healthy-lifestyle adoption, preferred methods for receiving information and factors that would engage participants in a risk-reduction programme. Groups were audiotaped, transcribed verbatim and analysed for thematic content using a framework approach. Twenty-two participants, 12 men, 10 women, mean age 71.4 (53-87) years, were included in the study. Three overarching themes emerged as barriers to healthy-lifestyle participation: physical, mental and environmental. Exercise participation difficulties spread across all three themes; healthy eating and smoking cessation concentrated in environmental and mental dimensions. Talks (discussions) were noted as participants' preferred method of information provision. Risk-reduction programmes considered attractive were stroke specific, convenient and delivered by healthcare professionals and involved both social and exercise components. Many stroke patients appear unable to adopt healthy-lifestyle changes through advice alone because of physical, mental and environmental barriers. Risk-reduction programmes including interactive education should be specifically tailored to address barriers currently experienced and extend beyond the stroke survivor to others in their environment who influence lifestyle choices.

    Full Text Available Introduction: Brucellosis is a zoonotic infection. Metabolism of trace elements such as zinc and copper can influence the response of immunity system and can activate host 's immunochemical mechanisms against the organism. Therefore, this study aimed to determine changes in serum levels of Zn and Cu in patients with brucellosis in pre and post treatment compared with healthy persons. Methods: In this individual matched case-control study, 26 patients participated who were admitted to infectious unit of Farshchian Hospital with brucellosis. Moreover, 26 healthy individuals were included in the control group. 5mL of venous blood was taken from all cases in pre-treatment as well post-treatment. Then, the serum samples were diluted with deionized water, and Cu and Zn levels were measured by using Atomic Absorption Spectrophotometer. Results: In this study, 26 patients with brucellosis were enrolled, who were 13 men (50% and 13 women (50%. No significant difference was observed between the patients and the control group in regard with their age and sex. Serum level of Cu in patients with brucellosis was found to be 100.31µg/dl and 92.81µg/dl, respectively before and after the treatment (P=0.495. Serum level of Cu in healthy individuals was reported to be 97.96µg/dl. In addition, serum level of Zn in the patients and controls was 93 µg/dl and 96.38 µg/dl, respectively (P= 0.625. Patients' Zn Serum level was found to be 90.27µg/dl after the treatment. Conclusion: In this study, no significant changes were observed in serum levels of copper and zinc in the patients with brucellosis in comparison with the control group. Besides, no significant changes were reported in serum levels of these elements in the patients in the end of treatment.

    The aim of this study was to assess the cognitive and behavioural development of children with healthy birth outcomes whose mothers were exposed to prenatal stress but did not experience pregnancy complications. In this prospective study, self-reported data, including the Prenatal Life Events Checklist about stressful life events (SLEs) during different stages of pregnancy, were collected at 32 to 34 weeks' gestation. Thirty-eight healthy females (mean age 27 y 8 mo, SD 2 y 4 mo) who were exposed to severe SLEs in the first trimester were defined as the exposed infant group, and 114 matched comparison participants were defined as the unexposed infant group (1:3). Maternal postnatal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale. The Bayley Scales of Infant Development and the Toddler Temperament Scale were used to evaluate the cognitive development and temperament characteristics of the infants with healthy birth outcomes when they were 16 to 18 months old. A randomized block multivariate analysis of covariance showed that the mental development index scores of the infants of mothers with prenatal exposure to SLEs in the first trimester averaged seven points (95% confidence interval 3.23-10.73 points) lower than those of the unexposed infants. Moreover, the infants in the exposed group achieved higher scores for regularity (adjusted mean [SD] 2.77 [0.65] vs. 2.52 [0.78], F(5,146) =5.27, p=0.023) and for persistence and attention span (adjusted mean 3.61 [0.72] vs. 3.35 [0.52], F(5,146) =5.51, p=0.020). This study provides evidence that lower cognitive ability and less optimal worse behavioural response in infants might independently result from prenatal maternal stress. © 2014 Mac Keith Press.

Discourse analysis can aid language assessment and diagnosis.Objective:[1] To explore narratives that produce a number of valid indicators for diagnosing aphasia in speakers of Brazilian Portuguese. [2] To analyze the macrostructural aspects of the discourse of normal individuals. [3] To analyze the macrostructural aspects of the discourse of aphasic individuals.Methods:The macrostructural aspects of three narratives produced by aphasic individuals and cognitively healthy subjects were analyzed.Results:A total of 30 volunteers were examined comprising 10 aphasic individuals (AG and 20 healthy controls (CG. The CG included 5 males. The CG had a mean age of 38.9 years (SD=15.61 and mean schooling of 13 years (SD=2.67 whereas the AG had a mean age of 51.7 years (SD=17.3 and mean schooling of 9.1 years (SD=3.69. Participants were asked to narrate three fairy tales as a basis for analyzing the macrostructure of discourse. Comparison of the three narratives revealed no statistically significant difference in number of propositions produced by the groups. A significant negative correlation was found between age and number of propositions produced. Also, statistically significant differences were observed in the number of propositions produced by the individuals in the CG and the AG for the three tales.Conclusion:It was concluded that the three tales are applicable for discourse assessment, containing a similar number of propositions and differentiating aphasic individuals and cognitively healthy subjects based on analysis of the macrostructure of discourse.

    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 (P0.05) 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.

    Background Infancy is an important life stage for obesity prevention efforts. Parents’ infant feeding practices influence the development of infants’ food preferences and eating behaviors and subsequently diet and weight. Mobile health (mHealth) may provide a feasible medium through which to deliver programs to promote healthy infant feeding as it allows low cost and easy access to tailored content. Objective The objective of this study was to describe the effects of an mHealth intervention on parental feeding practices, infant food preferences, and infant satiety responsiveness. Methods A quasi-experimental study was conducted with an mHealth intervention group (Growing Healthy) and a nonrandomized comparison group (“Baby's First Food"). The intervention group received access to a free app with age-appropriate push notifications, a website, and an online forum that provided them with evidence-based advice on infant feeding for healthy growth from birth until 9 months of age. Behavior change techniques were selected using the Behaviour Change Wheel framework. Participants in both groups completed three Web-based surveys, first when their infants were less than 3 months old (baseline, T1), then at 6 months (time 2, T2), and 9 months of age (time 3, T3). Surveys included questions on infant feeding practices and beliefs (Infant Feeding Questionnaire, IFQ), satiety responsiveness (Baby Eating Behaviour Questionnaire), and infant’s food exposure and liking. Multivariate linear regression models, estimated using maximum likelihood with bootstrapped standard errors, were fitted to compare continuous outcomes between the intervention groups, with adjustment for relevant covariates. Multivariate logistic regression adjusting for the same covariates was performed for categorical outcomes. Results A total of 645 parents (Growing Healthy: n=301, Baby's First Food: n=344) met the eligibility criteria and were included in the study, reducing to a sample size of 546

    Full Text Available Abstract Background Recently, a relationship between obesity and schizophrenia has been reported. Although fat- mass and fat free mass have been shown to be more predictive of health risk than body mass index, there are limited findings about body composition among patients suffering from schizophrenia. The aim of this study is to compare the body composition of schizophrenia patients with that of healthy subjects in Japan. Methods We recruited patients (n = 204, aged 41.3 ± 13.8 (mean ± SD years old with the DSM-IV diagnosis of schizophrenia who were admitted to psychiatric hospital using a cross-sectional design. Subjects' anthropometric measurements including weight, height, body mass index (BMI, and medications were also collected. Body fat, percent (% body fat, fat- free mass, muscle mass, and body water were measured using the bioelectrical impedance analysis (BIA method. Comparative analysis was performed with schizophrenic subjects and 204 healthy control individuals. Results In a multiple regression model with age, body mass index, and dose in chlorpromazine equivalents, schizophrenia was a significantly linked with more body fat, higher % body fat, lower fat- free mass, lower muscle mass, and lower body water among males. In females, schizophrenia had a significant association with lower % body fat, higher fat- free mass, higher muscle mass, and higher body water. Conclusions Our data demonstrate gender differences with regard to changes in body composition in association with schizophrenia. These results indicate that intervention programs designed to fight obesity among schizophrenic patients should be individualized according to gender.

    In this paper we address the formulation of two mechanistic water quality models that differ in the way the phytoplankton community is described. We carry out parameter estimation subject to differential-algebraic constraints and validation for each model and comparison between models performance. The first approach aggregates phytoplankton species based on their phylogenetic characteristics (Taxonomic group model) and the second one, on their morpho-functional properties following Reynolds' classification (Functional group model). The latter approach takes into account tolerance and sensitivity to environmental conditions. The constrained parameter estimation problems are formulated within an equation oriented framework, with a maximum likelihood objective function. The study site is Paso de las Piedras Reservoir (Argentina), which supplies water for consumption for 450,000 population. Numerical results show that phytoplankton morpho-functional groups more closely represent each species growth requirements within the group. Each model performance is quantitatively assessed by three diagnostic measures. Parameter estimation results for seasonal dynamics of the phytoplankton community and main biogeochemical variables for a one-year time horizon are presented and compared for both models, showing the functional group model enhanced performance. Finally, we explore increasing nutrient loading scenarios and predict their effect on phytoplankton dynamics throughout a one-year time horizon. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Food is an important driver of individual health, and an important subject in public policy and health intervention research. Viewpoints on what constitutes healthy nutrition, however, are manifold and highly subjective in nature, suggesting there is no one-size-fits-all behavioral change intervention. This research explores fundamental lay theories regarding healthy nutrition with consumers in Germany. The study aimed at identifying and characterizing distinct groups of consumers based on similarities and differences in the lay theories individuals hold by means of Q methodology. Thirty German consumers ranked a Q set of 63 statements representing a vast spectrum of individual opinions and beliefs on healthy nutrition into a quasi-normal distribution. Factor analysis identified four major lay theories on healthy nutrition: (1) "Healthy is what tastes good, in moderation", (2) "Healthy nutrition is expensive and inconvenient", (3) "Healthy is everything that makes me slim and pretty", and (4) "Only home-made, organic, and vegetarian food is healthy". Consensus existed among the theories about the question of whom to trust regarding nutritional information and the low relevance of information from official sources. Disagreement existed concerning the overall importance of healthy nutrition in day-to-day lives and whether food healthiness is related to organic or conventional production methods. The findings underscore that specific consumer groups should be engaged separately when intervening in healthy nutrition issues. Implications for public policies and intervention strategies are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The onset of type 2 diabetes mellitus can be prevented or delayed by lifestyle changes. Communication technologies such as a mobile phone can be used as a means of delivering these lifestyle changes. The purposes of this analysis were to explore applicability of potential components of a mobile phone-based healthy lifestyle program and to understand motivators and barriers to continued engagement in a mobile phone healthy lifestyle program. We conducted 6 focus groups (4 female and 2 male groups) in May and June 2010 with 35 focus group participants. The qualitative data were analyzed by 3 researchers using a qualitative description method in an ATLAS.ti software program. Inclusion criteria for enrollment in a focus group were as follows: (1) being aged from 30 to 69 years, (2) speaking and reading English, (3) having a sedentary lifestyle at work or during leisure time (screened by the Brief Physical Activity Survey questionnaire), and (4) having a body mass index (BMI) >25 kg/m(2) (Asian >23 kg/m(2)) based on self-reported weight and height or 5) having a self-reported prediabetic condition. The mean age was 51 (SD 10.6) years; 54% (n = 19) were white; 71% (n = 25) used a mobile phone at least once a week during the last month prior to the study enrollment; and mean BMI was 32.5 (SD 6.5) kg/m(2). In the qualitative analyses, the following 4 major themes and their subthemes emerged: (1) real-time social support (real-time peer support from participants who are similarly engaged in a diet or physical activity program, and professional support from health care providers or a researcher), (2) tailoring of mobile phone programs (3) self-monitoring and motivation, and (4) potential barriers and sustainability of the program (fear of failing, age and mobile technologies, and loss of interest over time). Participants from a wide range of age and racial groups expressed interest in a mobile phone-based lifestyle program. Such a program that incorporates the themes that we

Thirty two cats with no ocular abnormalities were used. Groups (n=8/each were formed with healthy cats that received 5mg g-1 of oral firocoxib (FH or no treatment (CH on day 0; seropositive cats for anti -T. gondii specific immunoglobulin G (IgG were grouped (n=8/each and treated in a similar fashion (FT and CT. On day 1, cats of all groups received the same treatment protocol, and 1h later, aqueocentesis was performed under general anesthesia (M0. Following 1h, the same procedure was repeated (M1. Quantitation of aqueous humor total protein and prostaglandin E2 (PGE2 were determined. Aqueous samples of seropositive cats were tested for anti- T. gondii specific IgG. In M0, aqueous samples of CT showed a significantly higher concentration of PGE2 in comparison with other groups (P<0.05. In all groups, PGE2 concentration increased significantly from M0 to M1 (P=0.001. PGE2 values did not change significantly between groups in M1 (P=0.17. Anti- T. gondii specific IgG were reported only in samples of M1, and aqueous titers did not change significantly between FT and CT (P=0.11. Although we have observed that aqueous humor PGE2 levels were significantly higher in cats of CT group during M0, such increase was not able to break the blood-aqueous barrier and cause anterior uveitis. Firocoxib did not prevent intraocular inflammation after aqueocentesis, in healthy and toxoplasmosis-seropositive cats.

    Full Text Available The g-ratio, quantifying the ratio between the inner and outer diameters of a fiber, is an important microstructural characteristic of fiber pathways and is functionally related to conduction velocity. We introduce a novel method for estimating the MR g-ratio non-invasively across the whole brain using high-fidelity magnetization transfer (MT imaging and single-shell diffusion MRI. These methods enabled us to map the MR g-ratio in vivo across the brain’s prominent fiber pathways in a group of 37 healthy volunteers and to estimate the inter-subject variability. Effective correction of susceptibility-related distortion artifacts was essential before combining the MT and diffusion data, in order to reduce partial volume and edge artifacts. The MR g-ratio is in good qualitative agreement with histological findings despite the different resolution and spatial coverage of MRI and histology. The MR g-ratio holds promise as an important non-invasive biomarker due to its microstructural and functional relevance in neurodegeneration.

    Full Text Available The choice of a reference posture is important when investigating rearfoot motion in clinical populations. The reference posture used may affect the magnitude of the peak angles and therefore may not enable comparison of the rearfoot kinematics across different populations. This study examined the relationship between the rearfoot frontal plane pattern of motion and three reference postures during the stance phase of walking in healthy and patellofemoral pain syndrome (PFPS subjects. The three reference postures investigated were: Relaxed Standing posture, subtalar joint neutral position (STJN and when the calcaneus and the lower leg were vertically aligned (Vertical Alignment. The rearfoot inversion/eversion during the stance phase was measured in 14 healthy subjects and 13 subjects with diagnosed PFPS using three dimensional motion analysis with the three different reference postures. The graphs of rearfoot inversion/eversion motion were overlaid with the angle at the rearfoot in the static posture and any intersection between the static angle and rearfoot motion was noted. An ANOVA showed significant differences in static posture between the groups for Relaxed Standing (p = 0.01, and STJN (p = 0.02. For both groups, with Relaxed Standing as a reference posture, the mean rearfoot pattern of motion did not intersect the Relaxed Standing static angle during the stance phase. The use of Vertical Alignment reference posture, however, showed an intersection of this reference posture through the rearfoot pattern of motion. The use of the Vertical Alignment reference posture also generated a typical rearfoot motion pattern for both groups and therefore it may be an appropriate reference posture for both healthy and PFPS individuals

    Full Text Available Previous studies have focused on the characteristics of ordinary facial expressions in patients with depression, and have not investigated the processing characteristics of ecological micro-expressions (MEs, i.e., MEs that presented in different background expressions in these patients. Based on this, adopting the ecological MEs recognition paradigm, this study aimed to comparatively evaluate facial ME recognition in depressed and healthy individuals. The findings of the study are as follows: (1 background expression: the accuracy (ACC in the neutral background condition tended to be higher than that in the fear background condition, and the reaction time (RT in the neutral background condition was significantly longer than that in other backgrounds. The type of ME and its interaction with the type of background expression could affect participants’ ecological MEs recognition ACC and speed. Depression type: there was no significant difference between the ecological MEs recognition ACC of patients with depression and healthy individuals, but the patients’ RT was significantly longer than that of healthy individuals; and (2 patients with depression judged happy MEs that were presented against different backgrounds as neutral and judged neutral MEs that were presented against sad backgrounds as sad. The present study suggested the following: (1 ecological MEs recognition was influenced by background expressions. The ACC of happy MEs was the highest, of neutral ME moderate and of sadness and fear the lowest. The response to the happy MEs was significantly shorter than that of identifying other MEs. It is necessary to conduct research on ecological MEs recognition; (2 the speed of patients with depression in identifying ecological MEs was slower than of healthy individuals; indicating that the patients’ cognitive function was impaired; and (3 the patients with depression showed negative bias in the ecological MEs recognition task, reflecting

    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.

    Several methods are used to estimate anaerobic threshold (AT) during exercise. The aim of the present study was to compare AT obtained by a graphic visual method for the estimate of ventilatory and metabolic variables (gold standard), to a bi-segmental linear regression mathematical model of Hinkley's algorithm applied to heart rate (HR) and carbon dioxide output (VCO2) data. Thirteen young (24 +/- 2.63 years old) and 16 postmenopausal (57 +/- 4.79 years old) healthy and sedentary women were submitted to a continuous ergospirometric incremental test on an electromagnetic braking cycloergometer with 10 to 20 W/min increases until physical exhaustion. The ventilatory variables were recorded breath-to-breath and HR was obtained beat-to-beat over real time. Data were analyzed by the nonparametric Friedman test and Spearman correlation test with the level of significance set at 5%. Power output (W), HR (bpm), oxygen uptake (VO2; mL kg(-1) min(-1)), VO2 (mL/min), VCO2 (mL/min), and minute ventilation (VE; L/min) data observed at the AT level were similar for both methods and groups studied (P > 0.05). The VO2 (mL kg(-1) min(-1)) data showed significant correlation (P automatic, non-invasive and objective AT measurement.

    Full Text Available Abstract Background: Heart failure with preserved ejection fraction is a syndrome characterized by changes in diastolic function; it is more prevalent among the elderly, women, and individuals with systemic hypertension (SH and diabetes mellitus. However, in its early stages, there are no signs of congestion and it is identified in tests by adverse remodeling, decreased exercise capacity and diastolic dysfunction. Objective: To compare doppler, echocardiographic (Echo, and cardiopulmonary exercise test (CPET variables - ergospirometry variables - between two population samples: one of individuals in the early stage of this syndrome, and the other of healthy individuals. Methods: Twenty eight outpatients diagnosed with heart failure according to Framingham’s criteria, ejection fraction > 50% and diastolic dysfunction according to the european society of cardiology (ESC, and 24 healthy individuals underwent Echo and CPET. Results: The group of patients showed indexed atrial volume and left ventricular mass as well as E/E’ and ILAV/A´ ratios significantly higher, in addition to a significant reduction in peak oxygen consumption and increased VE/VCO2 slope, even having similar left ventricular sizes in comparison to those of the sample of healthy individuals. Conclusion: There are significant differences between the structural and functional variables analyzed by Echo and CPET when comparing two population samples: one of patients in the early stage of heart failure with ejection fraction greater than or equal to 50% and another of healthy individuals.

    The purpose of the present study was to non-invasively compare ascending aortic blood flow and cross-sectional area (CSA) variations vs time in Mustard or Senning repaired (MSR) patients against those of healthy volunteers at rest. Velocity-encoded MR imaging was performed in 10 male patients (age range 18-24 years, median age 20.5 years) late after a Mustard or Senning correction, and in 10 male healthy volunteers (age range 21-25 years, median age 22.5 years), at the upper part of the ascending aorta. Both aortic cross-sectional area (CSA) and blood-flow variations were recorded over a complete cardiac cycle, with a 30-ms time of resolution. The body-surface area (BSA), the mean CSA over the systolic phase, and the BSA-normalized systemic ventricle power and work were significantly lower in the patient series compared with those of the volunteer series. The BSA-normalized right ventricle (RV) power and work of MSR patients were equal to 87 and 83% on average of those of the left ventricle (LV) of healthy volunteers. We conclude that, at rest, the mechanical performance of the systemic RV in MSR patients is significantly lower than that of the LV in healthy volunteers. Furthermore, the significantly lower aortic CSA found in MSR patients than in healthy volunteers may reveal an increase in the vasomotor tone. (orig.)

    Full Text Available Introduction: Migraine is a common familial disease and is diagnosed with recurring throbbing headache. Investigation of biological and psychological factors in the initiation and aggravation of migraine headaches have shown that there is a relationship between the psychological factors, personality, and migraine headache. Therefore, this study aimed to compare the conceived stress and Personality traits between ill persons suffering from Migraine and healthy people. Methods: This is an analytical cross-sectional study which involves a sample including 30 migrainours and 30 healthy people. The migraine-suffering participants were chosen among the people who referred to specialized clinic of migraine in Ardabil in the first half of 2012. The study participants filled the Eysenck's personality questionnaire and Kohen' s Perceived stress scale. Descriptive statistics as well as MANOVA were utilized to analyze the research data. Results: The results showed that migraine-suffering participants conceived the stress negatively (P<0.01, F=11 compared to healthy participants. Moreover, migrainours scored significantly higher in regard to Neuroticism score compared to healthy people (P<0.05, F=5.91. Also, there was a significant difference between migrainours and healthy people in their extroversion score (P<0.05, F=6.57. Conclusion: According to the study findings, it appears that migraine patients are more vulnerable to the neurotic disease. Therefore, considering the psychological and personality characteristics may impact on the prognosis of disease.

    The prevalence and magnitude of inter-arm BP difference (IAD) in young healthy patients is not well characterized. Flight academy applicants and designated aviators undergo annual evaluation that includes blood pressure (BP) measurement on both arms. All BP measurements performed from January 1, 2012, to April 30, 2012, were recorded and IAD was calculated. Results were compared between patients in whom BP was initially measured in the right arm (group 1), those in whom BP was initially measured in the left arm (group 2), and those in whom the arm in which BP was initially measured was not recorded (group 3). A total of 877 healthy patients had BP measured during the study period. In the entire group, mean systolic BP was the same in both arms. Absolute IAD was 5.6±5.5 mm Hg for systolic and 4.7±4.5 mm Hg for diastolic BP. IAD >10 mm Hg was recorded in 111 (12.6%) and 77 (8.8%) patients for systolic and diastolic BP, respectively. IAD was the same in the 3 groups and was unrelated to age, body mass index, and heart rate, but was related to systolic BP. IAD is common in young healthy patients, is not dependent on which arm was measured first, and unrelated to age, body mass index, and heart rate. © 2013 Wiley Periodicals, Inc.

    Full Text Available Introduction: Proximal and distal factors to the knee joint can be assumed as etiology of patellofemoral pain syndrome (PFPS. Some distal factors include excessive foot pronation and medial tibia torsion. The purpose of this study was to compare ankle musculature strength and rearfoot eversion in individuals with and without PFPS. Methods: Forty males (20 healthy and 20 patients voluntarily participated in this case-control study. Isometric ankle dorsiflexor and invertor muscles strength, rearfoot eversion range of motion (ROM, and Navicular depression were respectively evaluated by handheld dynamometer, goniometry, and Navicular Drop Test by a single examiner for both groups. To analyze the measurements, Independent Samples t test for parametric data and Mann-Whitney U test for nonparametric data at P0.05. Furthermore, no significant differences were observed between patients with PFPS and healthy counterparts regarding rearfoot eversion and Navicular depression (P>0.05. Conclusion: It can be deduced that isometric ankle dorsiflexor and invertor muscles strength, rearfoot eversion ROM, and foot pronation are not difference in patients with PFPS and healthy persons.

    Cognitive reserve has been implicated as a possible protective factor in multiple sclerosis (MS) but to date no study has compared reserve-building activities across disease course or to healthy controls. This study aims to describe differences in reserve-building activities across the MS disease course and healthy controls. Secondary analysis of a cross-sectional cohort study that included 276 healthy controls, and subjects with clinically isolated syndrome (CIS; n = 67), relapsing-remitting MS (RRMS; n = 358) and secondary progressive MS (PMS; n = 109). Past reserve-building activities were operationalized as occupational attainment and education. Current activities comprised 6 strenuous and 6 non-strenuous activities, including 5 reserve-building activities and television-watching. Multivariate Analysis of Variance models examined group differences in past and current activities, after adjusting for covariates. There were group differences in past and current reserve-building activities. SPMS patients had lower past reserve-building activities than healthy controls. All forms of MS engaged in fewer strenuous current reserve-building pursuits than healthy controls. RRMS read less than healthy controls. SPMS engaged in fewer job-related non-strenuous activities. All MS groups watched more television than healthy controls. MS patients show significantly fewer past and present reserve-building activities. Although it is difficult to establish causality without future prospective studies, lifestyle-modifying interventions should prioritize expanding MS patients' repertoire of strenuous and non-strenuous activities.

    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.

    Research suggests that core schemas are important in both the development and maintenance of psychosis. The aim of the study was to investigate and compare core schemas in four groups along the continuum of psychosis and examine the relationships between schemas and positive psychotic symptomatology. A measure of core schemas was distributed to 20 individuals experiencing first-episode psychosis (FEP), 113 individuals with "at risk mental states" (ARMS), 28 participants forming a help-seeking clinical group (HSC), and 30 non-help-seeking individuals who endorse some psychotic-like experiences (NH). The clinical groups scored significantly higher than the NH group for negative beliefs about self and about others. No significant effects of group on positive beliefs about others were found. For positive beliefs about the self, the NH group scored significantly higher than the clinical groups. Furthermore, negative beliefs about self and others were related to positive psychotic symptomatology and to distress related to those experiences. Negative evaluations of the self and others appear to be characteristic of the appraisals of people seeking help for psychosis and psychosis-like experiences. The results support the literature that suggests that self-esteem should be a target for intervention. Future research would benefit from including comparison groups of people experiencing chronic psychosis and people who do not have any psychotic-like experiences.

    There is no doubt about the beneficial effect of breastfeeding on the newborn's immune system. It is not fully elucidated what the differences are between the colostrum/milk of healthy and allergic mothers and how beneficial breastfeeding by an allergic mother is. The gene expression of selected cytokines was tested in cells isolated from colostra of healthy and allergic mothers using quantitative real-time PCR. Allergic phenotype was evident in colostral cells of allergic mothers: gene expressions of IL-4, IL-13 and EGF were increased and those of IFN-gamma decreased in comparison with colostral cells of healthy mothers. The allergic phenotype of the colostral cells of allergic mothers supporting the bias to a Th2 type response was found. It remains a question if a small number of these cells could influence the immature newborn immune system.

    Full Text Available Background & aim: Nowadays, the role and importance of psychosocial factors on physical health, as well as the influence of personality characteristics in having psychosomatic diseases such as cancer are of interest to many researchers. In spite of increase in breast cancer in Iran, very few studies have been carried out on risk factors of breast cancer. The aim of this study was to evaluate the comparative Behavioral inhibition / Activation System, type D and optimism in the breast cancer patients and healthy individuals. Methods: In the present casual-comparative study, 190 people (95 Patients and 95 Normal Subjects were selected in Rasht, Iran. Moreover, the groups were matched for demographic characteristics (age, gender and education. All individuals diagnosed with Breast Cancer and Normal Subjects received a Gary-Wilson Personality Questionnaire, Life Orientation Test and Type D Personality Scale. Collected data were analyzed using multivariate analysis of variance and regression. Results: The findings revealed that there were significant differences between cancer and normal groups in behavioral inhibition/activation system, type D Personality and optimism. In this regard, the Breast Cancer group had higher scores subscales of negative affect, social inhibition, passive avoidance, extinction and fight-flight than normal group. In addition, subscales of approach, active avoidance and optimism in the normal group were more than the Breast Cancer group. Conclusion: The present study supported the role of psychological variables in breast cancer patients which is essential for improving patients’ health and quality of life.

    (i) To identify determinants of participation in the 'Healthy School Canteen Program', a programme that encourages schools to set up their canteen in a way that promotes healthy dietary behaviour. (ii) To compare food supply and actions between participating and non-participating schools. (iii) To investigate what reasons schools have to increase attention for nutrition in the curriculum. A cross-sectional study based on information from questionnaires performed in 2010/2011. All secondary schools (age group 12-18 years) in the Netherlands (n 1145). Response was 33 % (n 375). Analyses included all schools with a canteen in which food is offered (28 %, n 325). None of the investigated determinants was associated with participation. Participating schools offered significantly (P schools. However, there was no difference in the number of less healthy products offered (e.g. candy bars, cakes and regular soft drinks). Participating schools reported more often that they took actions to improve dietary behaviour and more often had a policy on nutrition. Participating schools more often increased attention for nutrition in the curriculum in recent years than non-participating schools (57 % v. 43 %, P = 0·01). Reported reasons were similar and included media attention, eating behaviour of students and 'overweight'. Schools that participate in the programme seemed to offer more healthy products in their canteens and took more actions to improve dietary behaviour than non-participating schools. However, at all schools less healthy foods were also available.

Total antioxidant status (TAS, total oxidant status (TOS, oxidative stress index (OSI, and concentrations of coenzyme Q10 (CoQ10 and vitamins A and E were estimated in the plasma of 22 patients with AT, 12 children with NBS, and the healthy controls. In AT patients, TAS (median 261.7 μmol/L was statistically lower but TOS (496.8 μmol/L was significantly elevated in comparison with the healthy group (312.7 μmol/L and 311.2 μmol/L, resp.. Tocopherol (0.8 μg/mL and CoQ10 (0.1 μg/mL were reduced in AT patients versus control (1.4 μg/mL and 0.3 μg/mL, resp.. NBS patients also displayed statistically lower TAS levels (290.3 μmol/L, while TOS (404.8 μmol/L was comparable to the controls. We found that in NBS patients retinol concentration (0.1 μg/mL was highly elevated and CoQ10 (0.1 μg/mL was significantly lower in comparison with those in the healthy group. Our study confirms disturbances in redox homeostasis in AT and NBS patients and indicates a need for diagnosing oxidative stress in those cases as a potential disease biomarker. Decreased CoQ10 concentration found in NBS and AT indicates a need for possible supplementation.

    To investigate structural covariance networks (SCNs) as measured by regional gray matter volumes with structural magnetic resonance imaging (MRI) from healthy young adults, and to examine their consistency and stability. Two independent cohorts were included in this study: Group 1 (82 healthy subjects aged 18-28 years) and Group 2 (109 healthy subjects aged 20-28 years). Structural MRI data were acquired at 3.0T and 1.5T using a magnetization prepared rapid-acquisition gradient echo sequence for these two groups, respectively. We applied independent component analysis (ICA) to construct SCNs and further applied the spatial overlap ratio and correlation coefficient to evaluate the spatial consistency of the SCNs between these two datasets. Seven and six independent components were identified for Group 1 and Group 2, respectively. Moreover, six SCNs including the posterior default mode network, the visual and auditory networks consistently existed across the two datasets. The overlap ratios and correlation coefficients of the visual network reached the maximums of 72% and 0.71. This study demonstrates the existence of consistent SCNs corresponding to general functional networks. These structural covariance findings may provide insight into the underlying organizational principles of brain anatomy. © 2014 Wiley Periodicals, Inc.

    To compare the reliability of the Greulich-Pyle (GP) method, Tanner-Whitehouse 3 (TW3) method and Korean standard bone age chart (KS) in the evaluation of bone age of prepubertal healthy Korean children. Left hand-wrist radiographs of 212 prepubertal healthy Korean children aged 7 to 12 years, obtained for the evaluation of the traumatic injury in emergency department, were analyzed by two observers. Bone age was estimated using the GP method, TW3 method and KS, and was calculated in months. The correlation between bone age measured by each method and chronological age of each child was analyzed using Pearson correlation coefficient, scatterplot. The three methods were compared using one-way analysis of variance. Significant correlations were found between chronological age and bone age estimated by all three methods in whole group and in each gender (R2 ranged from 0.87 to 0.9, p < 0.01). Although bone age estimated by KS was slightly closer to chronological age than those estimated by the GP and TW3 methods, the difference between three methods was not statistically significant (p > 0.01). The KS, GP, and TW3 methods show good reliability in the evaluation of bone age of prepubertal healthy Korean children without significant difference between them. Any are useful for evaluation of bone age in prepubertal healthy Korean children.

    We aimed to investigate mastication predominance in healthy dentate individuals and patients with unilateral posterior missing teeth using objective and subjective methods. The sample comprised 50 healthy dentate individuals (healthy dentate group) and 30 patients with unilateral posterior missing teeth (partially edentulous group). Subjects were asked to freely chew three kinds of test foods (peanuts, beef jerky and chewing gum). Electromyographic activity of the bilateral masseter muscles was recorded. The chewing side (right side or left side) was judged by the level of root mean square electromyographic amplitude. Mastication predominance was then objectively assessed using the mastication predominant score and the mastication predominant index. Self-awareness of mastication predominance was evaluated using a modified visual analogue scale. Mastication predominance scores of the healthy dentate and partially edentulous groups for each test food were analysed. There was a significant difference in the distribution of the mastication predominant index between the two groups (P mastication predominant score was weakly correlated with self-awareness of mastication predominance in the healthy dentate group, whereas strong correlation was observed in the partially edentulous group (P mastication predominance and were more aware of mastication predominance than healthy dentate individuals. Our findings suggest that an objective evaluation of mastication predominance is more precise than a subjective method. © 2016 John Wiley & Sons Ltd.

    People's evaluations in the domain of healthy eating are at least partly determined by the choice context. We systematically test reference level and rank-based models of relative comparisons against each other and explore their application to social norms nudging, an intervention that aims at influencing consumers' behavior by addressing their inaccurate beliefs about their consumption relative to the consumption of others. Study 1 finds that the rank of a product or behavior among others in the immediate comparison context, rather than its objective attributes, influences its evaluation. Study 2 finds that when a comparator is presented in isolation the same rank-based process occurs based on information retrieved from memory. Study 3 finds that telling people how their consumption ranks within a normative comparison sample increases willingness to pay for a healthy food by over 30% relative to the normal social norms intervention that tells them how they compare to the average. We conclude that social norms interventions should present rank information (e.g., "you are in the most unhealthy 10% of eaters") rather than information relative to the average (e.g., "you consume 500 calories more than the average person").

    Full Text Available Physical activity has long been considered beneficial to health and regular exercise is purported to relieve stress. However empirical evidence demonstrating these effects is limited. In this study, we compared psychophysiological responses to an acute psychosocial stressor between individuals who did, or did not, report regular physical exercise. Healthy men and women (N=111 participated in two experimental sessions, one with the Trier Social Stress Test (TSST and one with a non-stressful control task. We measured heart rate, blood pressure, cortisol and self-reported mood before and at repeated times after the tasks.Individuals who reported physical exercise at least once per week exhibited lower heart rate at rest than non-exercisers, but the groups did not differ in their cardiovascular responses to the TSST. Level of habitual exercise did not influence self-reported mood before the tasks, but non-exercisers reported a greater decline in positive affect after the TSST in comparison to exercisers. These findings provide modest support for claims that regular exercise protects against the negative emotional consequences of stress, and suggest that exercise has beneficial effects in healthy individuals. These findings are limited by their correlational nature, and future prospective controlled studies on the effects of regular exercise on response to acute stress are needed.

    One third of adult patients with orthognathic surgery of a prognathic or retrognathic mandible show relapse. The sagittal split osteotomy of the mandible leads to a displacement of both parts up to 10 mm without any changes of muscle attachment. Changed mandible length needs adaptation of muscle capacity because of changed force to moment ratio. The aim of this Microarray study was to analyze the general genetic response of masseter muscle in patients with retrognathism or prognathism of the mandible six months after surgery in comparison with healthy untreated controls. We found in tissue samples from masseter muscle a reduction of different entities between patients and controls but less in retrognathic than in prognathic patients (274/429). The different entities to controls in prognathia were reduced from 1862 to 1749 but increased in retrognathia from 1070 to 1563. We have to consider that the total amount of different entities to the controls is higher in patients with prognathic mandible (7364) because of their strong genetic controlled development compared with that in patients with retrognathic mandible (4126), which is more environmentally influenced. It can be concluded that function follows form after surgical change with high inheritance. In retrognathic patients the adaptation could be delayed or the capacity of regeneration potential is not sufficient. Copyright © 2017 European Association for Cranio-Maxillo-Facial Surgery.

    In this qualitative study, we provide an in-depth understanding of the views of healthy aging among Thai elderly and explore the ways that contribute to healthy aging. Data were collected using focus groups and in-depth interviews in four selected provinces of Thailand, and were analyzed using content analysis. The results revealed that Thai elderly described being healthy as the result of multiple components involving physical, mental, and social well-being. Healthy aging was viewed as an absence of serious diseases, having functional independence, a positive psycho-emotional outlook, and making a social contribution. The factors considered to contribute to healthy aging included activities promoting physical and psychological health, as well as active engagement in social activities. Understanding how the elderly define healthy aging and identifying the most important components and factors that contribute to being healthy provides insight into possible policy implications and interventions to promote health and well-being among Thai elderly. © 2012 Wiley Publishing Asia Pty Ltd.

    To assess the efficacy of two school-based programmes to promote students' willingness to engage in lifestyle changes related to eating habits and physical activity behaviours. Elementary school-based health promotion intervention, designed as a multicomponent experimental study, based on a behavioural epidemiological model. Nine intervention and eight comparative public and private elementary schools. The goal was to determine the impact on the longitudinally assessed outcomes of two programmes that addressed healthy nutrition and active living in a cohort of 2038 children. The evaluations used pre-intervention and follow-up student surveys that were based on the Transtheoretical Model of the stages of behaviour change. In the intervention group, there were significant (P motivated teachers. The comparison group did not show significant differences between the pre- and post-intervention times for any of the stages of behaviour. The intervention programme encouraged the students to make healthy lifestyle choices related to eating habits and physical activity behaviours.

    Full Text Available OBJECTIVE: The schizophrenic patients with high suicide risk are characterized by depression, better cognitive function, and prominent positive symptoms. However, the neurobiological basis of suicide attempts in schizophrenia is not clear. The suicide in schizophrenia is implicated in the defects in emotional process and decision-making, which are associated with prefrontal-cingulate circuit. In order to explore the possible neurobiological basis of suicide in schizophrenia, we investigated the correlation of prefrontal-cingulate circuit with suicide risk in schizophrenia via dynamic casual modelling. METHOD: Participants were 33 first-episode schizophrenic patients comprising of a high suicide risk group (N = 14 and a low suicide risk group (N = 19. A comparison group of healthy controls (N = 15 were matched for age, gender and education. N-back tasking functional magnetic resonance imaging data was collected. RESULTS: Compared with healthy controls group, the two patients groups showed decreased task-related suppression during 2-back task state versus baseline state in the left posterior cingulate and medial prefrontal cortex; the hyper-connectivity from the left posterior cingulate cortex to the left medial prefrontal cortex existed in both schizophrenic patients groups, but hypo-connectivity in the opposite direction only existed in the schizophrenic patients group with high suicide risk. CONCLUSIONS: The hyper-connectivity from the left posterior cingulate cortex to the left medial prefrontal cortex may suggest that the abnormal effective connectivity was associated with risk for schizophrenia. The hypo-connectivity in the opposite direction may represent a possible correlate of increased vulnerability to suicide attempt.

    Full Text Available Introduction:Diabetes is a significant and expensive health problem which had influenced all the ages in almost all the countries. Increasing prevalence of this disease has been caused by continued changes in lifestyle such as unsuitable nutrition, lack of physical activities and fatness which is often related to modern city life, mechanization and industrialization. It is an expensive disease, both for patients and the health and hygienic care systems. This research tried to examine the relationship between lifestyle risk factors and type II diabetes. Methods: This research was a case-control type by random sampling and studying140 diabetes type II patients as case group and 140 healthy people accompanying some other patients as the control group at Tonekabon Shahid Rajaei hospital. People were of both sexes, between 30 and 64 years of age and Tonekabon residents. The questionnaire used included demographic, nutritional, physical activities, stress tolerance and smoking status information. The SPSS 11.5 and excel software were used for statistic calculation and for analysis of data, T and Chi-Square tests were applied. Results: By analyzing the data collected, there was a meaningful statistical relationship between physical activities, stress residence, nutrition, smoking and the diabetes type II disease (P-value0.05. Conclusion: Results imply that some risk factors important in diabetes type II include unsuitable nutrition such as having too much of sweets and sugar,lack of fruits, vegetables, fish, proteins and also lack of physical activities, stress tolerance and control.

  15. The healthy device and the definition of health: The example of the National Programme for a Healthy Life

    Full Text Available The National Programme for a Healthy Life emerges from the creation of three other programmes that encourage the so-called healthy habits among individuals. Due to be implemented by the National Ministry of Health between 2007 and 2010, it is not a unique case in its group, as the National Programme for a Healthy Life presents the opportunity to think about the importance of health in modern society. In the modern context of a transition that migrates from medicine as curative medicine to a conception of medicine as a preventive science, and from the perspective of the concept of biopolitics, developed by the French philosopher Michel Foucault, it is inferred the existence of a healthy mechanism which organizes the discourses on health and builds truthful discourses about it. The presence of this mechanism could be a possible explanation of the omnipresence of health in modern society, the constant concern to prolong life and the instigation of self-control, care and improvement of an individual's health

    Full Text Available Introduction. The association of diabetes and atherosclerosis with disorders of lipids and lipoproteins, notably high apolipoprotein B (apoB and low apolipoprotein A1(apoA1 is well established. Because of the beginning of the atherosclerosis' process from early life, in this study, the plasma levels of apoA1 and apoB were compared in diabetic children with type I diabetes mellitus(DM, healthy children with diabetic parents (HDPs,and healthy children with nondiabetic parents (HNDPs. Methods. This case-control study was conducted among 90 children aged 9–18 years. Serum levels of apoA and apoB were compared among 30 diabetic children (DM, 30 healthy children with diabetic parents (HDPs, and 30 healthy children with nondiabetic parents (HNDP. Results. The mean serum apoA1 was higher in DM (153±69 mg/dL followed by HNDPs (138±58 mg/dL and HDPs (128±56 mg/dl, but the difference was not statistically significant. The mean apoB value in HNDPs was significantly lower than DM and HDPs (90±21 mg/dL versus 127±47 and 128±38 mg/dL, P0.05. Conclusions. Diabetic children and healthy children with diabetic parent(s are at higher risk of dyslipidemia and atherosclerosis. Thus for primordial and primary prevention of atherosclerosis, we suggest screening these children for low plasma apoA1 and high plasma apoB levels.

    Conflicting messages about diet in the media, including publicity for "fad" diets, tend to distort the public's understanding of healthy eating. Several myths also persist, such as "skipping meals is a good way to lose weight," "all fats are bad" or "carbohydrates should be limited when trying to lose weight" Food labels, including the "traffic light" system, may also be confusing for some people. Food preferences vary between individuals, but health professionals can help guide individuals and towards a varied, balanced diet. This will include foods the individual and family enjoy, but based on appropriate proportions of all the five food groups, cooked in healthy ways. Some simple healthy eating tips are given to pass on to clients.

  18. Hair and stress: A pilot study of hair and cytokine balance alteration in healthy young women under major exam stress.

    Full Text Available Mouse models show that experimental stress mimicking prolonged life-stress exposure enhances neurogenic inflammation, induces adaptive immunity cytokine-imbalance characterized by a shift to Type 1 T-helper cell cytokines and increases apoptosis of epithelial cells. This affects hair growth in otherwise healthy animals. In this study, we investigate whether a prolonged naturalistic life-stress exposure affects cytokine balance and hair parameters in healthy humans. 33 (18 exam, 15 comparison female medical students with comparable sociobiological status were analyzed during a stressful final examination period, at three points in time (T 12 weeks apart. T1 was before start of the learning period, T2 between the three-day written exam and an oral examination, and T3 after a 12 week rest and recovery from the stress of the examination period. Assessments included: self-reported distress and coping strategies (Perceived Stress Questionnaire [PSQ], Trier Inventory for the Assessment of Chronic Stress [TICS], COPE, cytokines in supernatants of stimulated peripheral blood mononucleocytes (PBMCs, and trichogram (hair cycle and pigmentation analysis. Comparison between students participating in the final medical exam at T2 and non-exam students, revealed significantly higher stress perception in exam students. Time-wise comparison revealed that stress level, TH1/TH2 cytokine balance and hair parameters changed significantly from T1 to T2 in the exam group, but not the control. However, no group differences were found for cytokine balance or hair parameters at T2. The study concludes that in humans, naturalistic stress, as perceived during participation in a major medical exam, has the potential to shift the immune response to TH1 and transiently hamper hair growth, but these changes stay within a physiological range. Findings are instructive for patients suffering from hair loss in times of high stress. Replication in larger and more diverse sample

    Infancy is an important life stage for obesity prevention efforts. Parents' infant feeding practices influence the development of infants' food preferences and eating behaviors and subsequently diet and weight. Mobile health (mHealth) may provide a feasible medium through which to deliver programs to promote healthy infant feeding as it allows low cost and easy access to tailored content. The objective of this study was to describe the effects of an mHealth intervention on parental feeding practices, infant food preferences, and infant satiety responsiveness. A quasi-experimental study was conducted with an mHealth intervention group (Growing Healthy) and a nonrandomized comparison group ("Baby's First Food"). The intervention group received access to a free app with age-appropriate push notifications, a website, and an online forum that provided them with evidence-based advice on infant feeding for healthy growth from birth until 9 months of age. Behavior change techniques were selected using the Behaviour Change Wheel framework. Participants in both groups completed three Web-based surveys, first when their infants were less than 3 months old (baseline, T1), then at 6 months (time 2, T2), and 9 months of age (time 3, T3). Surveys included questions on infant feeding practices and beliefs (Infant Feeding Questionnaire, IFQ), satiety responsiveness (Baby Eating Behaviour Questionnaire), and infant's food exposure and liking. Multivariate linear regression models, estimated using maximum likelihood with bootstrapped standard errors, were fitted to compare continuous outcomes between the intervention groups, with adjustment for relevant covariates. Multivariate logistic regression adjusting for the same covariates was performed for categorical outcomes. A total of 645 parents (Growing Healthy: n=301, Baby's First Food: n=344) met the eligibility criteria and were included in the study, reducing to a sample size of 546 (Growing Healthy: n=234, Baby's First Food: n=312

    Introduction Endothelin-1 (ET-1) is a potent vasoconstrictive peptide with multi functional activity in various systemic diseases. Previous studies indicate the detection of ET-1 in gingival tissues and gingival crevicular fluid. Aim The aim of this study was to estimate the serum ET-1 levels in clinically healthy subjects and subjects with chronic periodontitis, before and after treatment, and correlate it with the clinical parameters. Materials and Methods A total of 44 patients were included in the study. Group I comprised of 20 subjects with clinically healthy periodontium. Group II comprised of 24 subjects with chronic periodontitis. Group III comprised of same Group II subjects following periodontal management. Serum samples were collected from the subjects and an Enzyme Linked Immunosorbent Assay (ELISA) was done to estimate the ET-1 levels. The ET-1 levels were then correlated among the three groups with the clinical parameters namely, Plaque Index (PI), Sulcus Bleeding Index (SBI), probing pocket depth, clinical attachment loss and Periodontally Inflamed Surface Area (PISA). The independent t-test and paired t-test were used for comparison of clinical parameters and Pearson’s correlation coefficient test was used for correlating the ET-1 levels. Results ET-1 levels in chronic periodontitis subjects were significantly higher compared to healthy subjects (p<0.001). However, the clinical parameters did not statistically correlate with the ET-1 levels. There was a significant decrease in ET-1 levels following treatment (p<0.001). Conclusion Serum ET-1 is increased in chronic periodontitis and reduces after periodontal therapy. Further studies are required to establish ET-1 as a biomarker for periodontal disease.

    Full Text Available Abstract Background Opioid-substitution treatment (OST for opioid dependence (OD has proven effective in retaining patients in treatment and reducing illegal opiate abuse and crime. Consequently, the World Health Organization (WHO has listed the opioid agonists methadone and buprenorphine as essential drugs for OD that should be available worldwide. In many areas of the world, OD is often associated with concomitant benzodiazepine (BZD dependence and abuse, which complicates treatment. However, possible changes in the cognitive functioning of these patients are not well-known. The present study is the first to examine longitudinal stability of memory function in OST patients with BZD use, thus providing a new tool for health policy authorities in evaluating the usefulness of OST. Methods Within the first two months (T1 and between 6–9 months (T2 after OST admission, we followed the working memory, immediate verbal memory, and memory consolidation of 13 methadone- and 15 buprenorphine- or buprenorphine/naloxone-treated patients with BZD dependence or abuse disorder. The results were compared to those of fifteen normal comparison participants. All participants also completed a self-reported memory complaint questionnaire on both occasions. Results Both patient groups performed statistically significantly worse than normal comparison participants in working memory at time points T1 and T2. In immediate verbal memory, as measured by list learning at T1, patients scored lower than normal comparison participants. Both patient groups reported significantly more subjective memory problems than normal comparison participants. Patients with more memory complaints recalled fewer items at T2 from the verbal list they had learned at T1 than those patients with fewer memory complaints. The significance of the main analyses remained nearly the same when the statistical tests were performed without buprenorphine-only patients leaving 12 patients to

    A gap exists in the literature regarding aggression in autism spectrum disorders (ASD) and how this behavior compares to other groups. In this multisite study, the Children’s Scale for Hostility and Aggression: Reactive/Proactive (C-SHARP) and the Aggression subscale of the Child Behavior Checklist (CBCL) were rated for 414 children with ASD (Autistic Disorder, 69%; PDD-NOS, 24%; Asperger’s Disorder, 7%) and 243 clinic-referred children without ASD, aged 1-21 years (mean age about 7). Participants were not selected for aggressive behavior. Relative to the comparison group, children with ASD were reported to have less aggression and were more likely to be rated as reactive rather than proactive. Among all subjects, sex was not associated with aggression; higher IQ/adaptive behavior and older age were associated with more sophisticated types of aggression while lower scores on IQ, adaptive behavior, and communication measures were associated with more physical aggression. The interaction between demographic variables and diagnosis was significant only for age: younger but not older children with ASD showed less aggression than clinic-referred controls. PMID:24497627

    Very little is known about arsenic (As) metabolism in healthy populations that are not exposed to high concentrations of As in their food or water. Here we present a study with healthy volunteers from three different ethnic groups, residing in Leicester, UK, which reveals statistically significant differences in the levels of total As in urine and fingernail samples. Urine (n = 63), hair (n = 36) and fingernail (n = 36) samples from Asians, Somali Black-Africans and Whites were analysed using inductively coupled plasma mass spectrometry (ICP-MS) and graphite furnace atomic absorption spectroscopy (GF-AAS). The results clearly show that the total concentrations of As in urine and fingernail samples of a Somali Black-African population (urine 7.2 μg/g creatinine; fingernails 723.1 μg/kg) are significantly (P 0.05) in the level of As in the hair samples from these three groups; Somali Black-Africans (116.0 μg/kg), Asians (117.4 μg/kg) and Whites (141.2 μg/kg). Significantly different levels of total As in fingernail and urine and a higher percentage of urinary DMA in the Somali Black-Africans are suggestive of a different pattern of As metabolism in this ethnic group

    To investigate the combined influence of diet quality and physical activity on cardiovascular disease (CVD) risk factors in adolescents, adolescents (n = 1513; 12.5-17.5 years) participating in the Healthy Lifestyle in Europe by Nutrition in Adolescence study were studied. Dietary intake was registered using a 24-h recall and a diet quality index was calculated. Physical activity was assessed by accelerometry. Lifestyle groups were computed as: healthy diet and active, unhealthy diet but active, healthy diet but inactive, and unhealthy diet and inactive. CVD risk factor measurements included cardiorespiratory fitness, adiposity indicators, blood lipid profile, blood pressure, and insulin resistance. A CVD risk score was computed. The healthy diet and active group had a healthier cardiorespiratory profile, fat mass index (FMI), triglycerides, and high-density lipoprotein cholesterol (HDL-C) levels and total cholesterol (TC)/HDL-C ratio (all P ≤ 0.05). Overall, active adolescents showed higher cardiorespiratory fitness, lower FMI, TC/HDL-C ratio, and homeostasis model assessment index and healthier blood pressure than their inactive peers with either healthy or unhealthy diet (all P ≤ 0.05). Healthy diet and active group had healthier CVD risk score compared with the inactive groups (all P ≤ 0.02). Thus, a combination of healthy diet and active lifestyle is associated with decreased CVD risk in adolescents. Moreover, an active lifestyle may reduce the adverse consequences of an unhealthy diet. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  5. Emotion recognition in early Parkinson's disease patients undergoing deep brain stimulation or dopaminergic therapy: a comparison to healthy participants

    Full Text Available Parkinson’s disease (PD is traditionally regarded as a neurodegenerative movement disorder, however, nigrostriatal dopaminergic degeneration is also thought to disrupt non-motor loops connecting basal ganglia to areas in frontal cortex involved in cognition and emotion processing. PD patients are impaired on tests of emotion recognition, but it is difficult to disentangle this deficit from the more general cognitive dysfunction that frequently accompanies disease progression. Testing for emotion recognition deficits early in the disease course, prior to cognitive decline, better assesses the sensitivity of these non-motor corticobasal ganglia-thalamocortical loops involved in emotion processing to early degenerative change in basal ganglia circuits. In addition, contrasting this with a group of healthy aging individuals demonstrates changes in emotion processing specific to the degeneration of basal ganglia circuitry in PD. Early PD patients (EPD were recruited from a randomized clinical trial testing the safety and tolerability of deep brain stimulation of the subthalamic nucleus (STN-DBS in early-staged PD. EPD patients were previously randomized to receive optimal drug therapy only (ODT, or drug therapy plus STN-DBS (ODT+DBS. Matched healthy elderly controls (HEC and young controls (HYC also participated in this study. Participants completed two control tasks and three emotion recognition tests that varied in stimulus domain. EPD patients were impaired on all emotion recognition tasks compared to HEC. Neither therapy type (ODT or ODT+DBS nor therapy state (ON/OFF altered emotion recognition performance in this study. Finally, HEC were impaired on vocal emotion recognition relative to HYC, suggesting a decline related to healthy aging. This study supports the existence of impaired emotion recognition early in the PD course, implicating an early disruption of fronto-striatal loops mediating emotional function.

    Gender role, independent of biological sex, affects health. However, research on healthy eating that considers the importance of gender norms is scarce. People who are androgynous and have high masculinity and femininity are reported to have better health practices than other people. The present study aimed to examine the differences in health literacy (HL) and self-efficacy for healthy eating by gender role in Japanese men and women. Participants were 629 men and women aged 25-34 years, recruited via a Japanese Internet research company database. Participants were categorized into four gender role groups using the Japanese Gender Role Index. HL and self-efficacy for healthy eating were assessed using the healthy eating literacy (HEL) scale and the healthy eating and weight self-efficacy (HEWSE) scale. Analysis of variance with Bonferroni-adjusted post hoc tests and hierarchical multiple regression were used to test the research hypotheses. We found that the Androgynous group had significantly higher HEL and HEWSE scores than the Feminine and Undifferentiated groups. The Masculine group scored significantly higher on both measures than the Undifferentiated group. Being Androgynous (HEL: β = 0.34, p gender role orientation and individual HL and self-efficacy for healthy eating. These findings may be relevant for promoting healthy eating from the perspective of gender norms.

    Full Text Available Objective: Polycystic ovary syndrome (PCOS is one of the most common endocrine disorders that is associated with different metabolic, reproductive and psychological consequences. The main aim of this study was to compare the sexual function and quality of life in women with polycystic ovary syndrome and healthy women.Materials and methods: This is a causal-comparative study in which 129 women with polycystic ovary syndrome were qualified as the research group. The control group consisted of 125 healthy women. The sampling method was convenient and was done using Rotterdam criteria. Women of both research and control groups responded to the FSFI and WHOQOL-BREF questionnaires. Data were analyzed with SPSS software using MANOVA.Results: According to findings, all of quality of life subscales except environment domain were significantly lower in research group than healthy group (p < 0.01, but none of sexual function subscales were significantly different between two groups (p > 0.05.Conclusion: Women with PCOS in term of some quality of life parameters have lower performance than healthy women. Therefore, it seems to be essential to increase awareness about symptoms and psychological consequences and referring process in order to take advantage of the advisory services.

    Recent resting-state functional connectivity MRI studies using group-level statistical analysis have demonstrated the inheritable characters of schizophrenia. The objective of the present study was to use pattern classification as a means to investigate schizophrenia inheritance based on the whole-brain resting-state functional connectivity at the individual subject level. One-against-one pattern classifications were made amongst three groups (i.e. patients diagnosed with schizophrenia, healthy siblings, and healthy controls after preprocessing), resulting in an 80.4% separation between patients with schizophrenia and healthy controls, a 77.6% separation between schizophrenia patients and their healthy siblings, and a 78.7% separation between healthy siblings and healthy controls, respectively. These results suggest that the healthy siblings of schizophrenia patients have an altered resting-state functional connectivity pattern compared with healthy controls. Thus, healthy siblings may have a potential higher risk for developing schizophrenia compared with the general population. Moreover, this pattern differed from that of schizophrenia patients and may contribute to the normal behavior exhibition of healthy siblings in daily life.

    Health is a multi-dimensional concept, capturing how people feel and function. The broad concept of Active and Healthy Ageing was proposed by the World Health Organisation (WHO) as the process of optimizing opportunities for health to enhance quality of life as people age. It applies to both...... individuals and population groups. A universal Active and Healthy Ageing definition is not available and it may differ depending on the purpose of the definition and/or the questions raised. While the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) has had a major impact......, a definition of Active and Healthy Ageing is urgently needed. A meeting was organised in Montpellier, France, October 20-21, 2014 as the annual conference of the EIP on AHA Reference Site MACVIA-LR (Contre les Maladies Chroniques pour un Vieillissement Actif en Languedoc Roussillon) to propose an operational...

    Full Text Available Background: Alopecia areata (AA is a common cause of noncicatricial alopecia that occurs as a patchy, confluent or diffuse pattern. Exact etiologic factor of AA not yet recognized. Among many hypothesis, relationship between AA and autoimmune disease, especially thyroid disorders, was more interesting. The objective of this study was to determine the prevalence of thyroid test disorders in the patients with alopecia totalis and universalis in comparison with normal population.Methods: We analyzed medical records of 100 patients, including 44 male and 56 female in Tehran Razi Hospital from 1388 to 1389. The mean age was 24.1 years. Patients having totalis and universalis form of AA considered as case group while 100 normal person (42 male and 58 female with mean age of 26.1 who had not any form of AA considered as control group. Both groups had not any sign of thyroid disease at clinical examination according to their available medical records. Collected data were analyzed statistically in SPSS software 17th version. Results: In the majority of patients (54% the disease was manifested in the first two decades of life. History of atopia was seen in 9.8% of patient. Presence of the similar disease in first-degree family members was seen in 14.3% of patients. Abnormal T3, T4 and TSH were significantly higher in case group. Abnormal T3 uptake was higher in case group but not statistically significant. Conclusion: Paraclinical thyroid disorders were significantly higher in the alopecia areata patients than in normal population. There was no significant association between the age, sex and duration of disease and presence thyroid dysfunction.

    The goal of this study was to assess the effect of novelty on correct recognition (hit minus false alarms) and on recollection and familiarity processes in normal aging and amnestic mild cognitive impairment (MCI). Recognition tasks compared well-known and novel stimuli in the verbal domain (words vs. pseudowords) and in the musical domain (well-known vs. novel melodies). Results indicated that novel materials associated with lower correct recognition and lower recollection, an effect that can be related to its lower amenability to elaborative encoding in comparison with well-known items. Results also indicated that normal aging impairs recognition of well-known items, whereas MCI impairs recognition of novel items only. Healthy older adults showed impaired recollection and familiarity relative to younger controls and individuals with MCI showed impaired recollection relative to healthy older adults. The recollection deficit in healthy older adults and persons with MCI and their impaired recognition of well-known items is compatible with the difficulty both groups have in encoding information in an elaborate manner. In turn, familiarity deficit could be related to impaired frontal functioning. Therefore, novelty of material has a differential impact on recognition in persons with age-related memory disorders.

    Human aging is a lifelong process characterized by a continuous trade-off between pro-and anti-inflammatory responses, where the best-adapted and/or remodeled genetic/epigenetic profile may develop a longevity phenotype. Centenarians and their offspring represent such a phenotype and their comparison to patients with age-related diseases (ARDs) is expected to maximize the chance to unravel the genetic makeup that better associates with healthy aging trajectories. Seemingly, such comparison is expected to allow the discovery of new biomarkers of longevity together with risk factor for the most common ARDs. MicroRNAs (miRNAs) and their shuttles (extracellular vesicles in particular) are currently conceived as those endowed with the strongest ability to provide information about the trajectories of healthy and unhealthy aging. We review the available data on miRNAs in aging and underpin the evidence suggesting that circulating miRNAs (and cognate shuttles), especially those involved in the regulation of inflammation (inflamma-miRs) may constitute biomarkers capable of reliably depicting healthy and unhealthy aging trajectories.

    Research supports the efficacy of both cognitive dissonance (CD) and healthy weight (HW) eating disorders prevention, and indicates that CD can be delivered by peer-facilitators, which facilitates dissemination. This study investigated if peer-facilitators can deliver HW when it is modified for their use and extended follow-up of peer-facilitated CD as compared to previous trials. Based on pilot data, we modified HW (MHW) to facilitate peer delivery, elaborate benefits of the healthy-ideal, and place greater emphasis on consuming nutrient dense foods. Female sorority members (N=106) were randomized to either two 2-h sessions of CD or MHW. Participants completed assessment pre- and post-intervention, and at 8
