Given the evidence that regular physical activity produces substantial health benefits, participation in sports, exercise, and recreation is widely encouraged. The objective of this study was to describe participation in sports, exercise, and recreational physical activities among US adults. Data from 2 national surveys of respondents age 18 years and older were analyzed. Respondents to the American Time Use Survey (ATUS) from 2003 through 2005 (N=45,246) reported all activities on 1 randomly selected survey day. Respondents to the National Health and Nutrition Examination Survey (NHANES) from 1999 through 2004 (N=17,061) reported leisure-time physical activities in the 30 days before the interview. One-quarter of adults participated in any sport, exercise, or recreational activity on a random day, and 60.9% of adults participated in any leisure-time activity in the previous 30 days. The most common types of activities were walking, gardening and yard work, and other forms of exercise. The sports and recreational activities had typical durations of 1/2 to 3 hours per session, and the exercise activities typically lasted 1 hour or less. The prevalence of sports, exercise, and recreational physical activities is generally low among US adults; exercise is the most commonly reported type of activity.

Exposure to pesticides has been associated with mental disorders, especially in occupationally exposed populations, such as farmers. This effect has been attributed to the neurotoxic and endocrine-disrupting activity of pesticides, as suggested by experimental studies. To determine the prevalence of common mental disorders and self-reported depression, and analyze their association with the exposure to pesticides in a rural population resident in the municipality of Dom Feliciano, Rio Grande do Sul, where tobacco farming is the main economic activity. A cross-sectional study evaluating the prevalence of common mental disorders and self-reported depression in a sample of 869 adult individuals resident in Dom Feliciano, between October 2011 and March 2012 was performed. The evaluation of common mental disorders was performed using the Self-Reporting Questionnaire (SRQ-20), setting a cutoff point of 8 for both genders. A standardized questionnaire was used to obtain information on self-reported depression upon prior diagnosis by a health professional, and self-reported exposure to pesticide. In order to evaluate the association between exposure to pesticides and mental disorders, a non-conditional multivariate logistic regression analysis was performed. The prevalence of common mental disorders and self-reported depression in the sample population were 23% and 21%, respectively. Among individuals who reported depression, an increase of 73% was observed in the odds of pesticide exposure at an age equal to or less than 15 years. There was a positive association between self-reported pesticide poisoning and common mental disorders (OR=2.63; 95% CI, 1.62-4.25) as well as self-reported depression (OR=2.62; 95% CI, 1.63-4.21). Individuals who reported depression had a greater odds of exposure to pyrethroids (OR=1.80; 95% CI, 1.01-3.21) and aliphatic alcohol (OR=1.99; 95% CI, 1.04-3.83). An SRQ-20≥8 was associated with an approximately seven times higher odds of exposure to aliphatic alcohol (95% CI, 1.73-27.53). Self-reported depression positively correlated with a greater period of exposure to dinitroaniline (OR=2.20; 95% CI, 1.03-4.70) and sulphonylurea (OR=4.95; 95% CI, 1.06-23.04). The results suggest that exposure to pesticides could be related mental disorders. However, other common risk factors in tobacco farming, the main local economic activity, cannot be excluded.

Provide data on the distribution of parent- and teacher-reported symptoms of ADHD in childhood epilepsy and describe coexisting cognitive and behavioral disorders in children with both epilepsy and ADHD. Eighty-five (74% of those eligible) children (5-15 years) in a population-based sample with active epilepsy underwent psychological assessment. The ADHD Rating Scale-IV (ADHD-RS-IV) scale was completed by parents ( n = 69) and teachers ( n = 67) of participating children with an IQ > 34. ADHD was diagnosed with respect to Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.). Parents reported significantly more symptoms of ADHD than teachers ( p < .001). Symptoms of inattention were more commonly reported than symptoms of hyperactivity-impulsivity ( p < .001). Neurobehavioral comorbidity was similar in those with ADHD and non-ADHD with the exception of oppositional defiant disorder (ODD) and developmental coordination disorder (DCD), which were more common in those with both epilepsy and ADHD. Symptoms of ADHD are very common in childhood epilepsy but prevalence is influenced by informant.

The three most common leisure time activities of 2,200 third and fourth grade children (mean age 8.8 + 0.8; 50.7% girls) and the association of the intensity levels of those activities with demographic variables and risk factors for cardiovascular disease are reported. Activities reported most often by boys were playing video games (33%), playing football (32%), bicycling (31%), watching television (28%), and playing basketball (26%). The girls reported doing homework (39%), bicycling (31%), watching television (30%), dancing (27%), and reading (23%). Overall, the children, especially girls, reported fairly sedentary activities, with an average metabolic equivalent level of 4.2 for girls and 4.8 for boys. Among boys, African Americans reported more vigorous activities than Whites, but the activities reported by White girls were somewhat more vigorous than those reported by non-White girls. Children from a higher socioeconomic status (SES), especially boys, reported a greater proportion of sedentary activities than lower SES children. The risk factors of cholesterol, blood pressure, skinfold thickness, and body mass index were not significantly associated with total activity score. However, significantly more nonobese than obese children reported a vigorous (high-intensity) activity as one of their top three activities.

Use of energy drinks and energy shots among military personnel is controversial. High amounts of caffeine (the primary active ingredient in these products) may impact performance of military duties. The impact of caffeine overconsumption and potential subsequent side effects that might be experienced by service members with unique roles and responsibilities is a concern. Reported here are the prevalence of use, reasons for use, and side effects associated with consumption of energy drinks and energy shots among several populations of active duty personnel in the US military. A snowball survey was sent to over 10,000 active duty personnel. A total of 586 (∼6% response rate) individuals completed a 30-item electronic survey. Over half of respondents (53%) reported consuming an energy drink at least once in the past 30 days. One in five (19%) reported energy shot consumption in the prior 30 days. One in five (19%) also reported consuming an energy drink in combination with an alcoholic beverage. Age and gender were significantly associated with energy drink consumption. Young male respondents (18-29 years) reported the highest use of both energy drinks and energy shots. Among those reporting energy drink and energy shot use, the most common reasons for consumption were to improve mental alertness (61%) and to improve mental (29%) and physical (20%) endurance. Nearly two-thirds (65%) of users self-reported at least one side effect. The most commonly reported side effects included increased pulse rate/palpitations, restlessness, and difficulty sleeping. Use of energy products among military personnel is common and has the potential to impact warrior health and military readiness. © 2014 International Life Sciences Institute.

The paper reports findings from a multidisciplinary programme of research, the major aims of which were to determine the nature and extent of the New Zealand adventure tourism injury problem. Analysis of hospital discharge and mortality data for a 15-year period identified adventure tourism-related activities as contributing to approximately 20% of overseas visitor injuries, and 22% of fatalities. Activities that commonly involve independent-unguided adventure tourism, notably mountaineering, skiing and tramping, contributed most to injury and fatality incidence. Horse riding and cycling activities were identified from hospital discharge data and adventure tourism operators' reported client injury-incidence, as the commercial adventure tourism activities most frequently involved in client injuries. Falls were the most common injury events, and a range of client, equipment, environmental and organisational risk factors were identified. Possible interventions to reduce injury risk among overseas and domestic adventure tourists are discussed.

Little is known about the types of physical activities that older individuals with lower-limb loss perform, correlates of regular physical activity (PA), and barriers and facilitators to PA. We conducted an exploratory study in 158 older Veterans from the Pacific Northwest with a partial foot (35%), below-knee (39%) and above-knee (26%) amputation. Ninety-eight percent of survey respondents were male, on average 65 yr of age and 15 yr postamputation; 36% of amputations were trauma-related. The most commonly reported physical activities were muscle strengthening (42%), yard work and/or gardening (30%), and bicycling (11%). Forty-three percent were classified as physically active based on weekly moderate- and vigorous-intensity PA. History of vigorous preamputation PA was positively associated with being active, while low wealth and watching ≥5 h/d of television/videos were inversely associated. While pain- and resource-related barriers to PA were most frequently reported, only knowledge-related and interest/motivation-related barriers were inversely associated with being active. Family support and financial assistance to join a gym were the most commonly reported factors that would facilitate PA. To increase PA in the older amputee population, interventions should address motivational issues, knowledge gaps, and television watching; reduce financial barriers to exercising; and consider involving family members.

2014-01-01

Using data from a nationally representative British birth cohort we characterized the type and diversity of leisure-time physical activity that 2,188 participants (age 60–64 years) engaged in throughout the year by gender and obesity. Participants most commonly reported walking (71%), swimming (33%), floor exercises (24%) and cycling (15%). Sixty-two percent of participants reported ≥2 activities in the past year and 40% reported diversity on a regular basis. Regular engagement in different types of activity (cardio-respiratory, balance/flexibility and strength) was reported by 67%, 19% and 11% of participants, respectively. We found gender differences, as well as differences by obesity status, in the activities reported, the levels of activity diversity and activity type. Non-obese participants had greater activity diversity, and more often reported activities beneficial for cardio-respiratory health and balance/flexibility than obese participants. These findings may be used to inform the development of trials of physical activity interventions targeting older adults, and those older adults with high body mass index. PMID:24911018

: Understanding parental barriers is crucial to promote active commuting to school since the parental perceptions influence how young people commute. This study examined parental barriers to active commuting to school among Spanish children and adolescents, and their association with their gender and the usual mode of commuting. Parents of children ( n = 628) and parents of adolescents ( n = 151) from Granada (Spain) completed a paper-based questionnaire about perceived parental barriers to active commuting to school and mode of commuting. Data were analyzed using the Chi-square test. Among Spanish parents, the most common barriers reported by parents of children were traffic volume and dangerous intersections, whereas the most frequent barriers reported by parents of adolescents were distance to school and dangerous intersections. Compared to parents of children, a greater proportion of parents of adolescents reported distance to school and crime and smaller proportion reported traffic volume as barriers to active commuting to school. Among parents of children, crime was a more commonly reported as a barrier by parents of girls. Although some barriers reported by parents of passive commuters were similar for children and adolescents (such as distance to school and absence of a policeman at crosswalks), other barriers were specific to parents of children. The main parental barriers to active commuting in children were traffic volume and dangerous intersections whereas for adolescents were distance and dangerous intersections. Among Spanish parents, parental barriers to active commuting are influenced by children's age, gender and mode of commuting to school. © The Author 2017.

Evaluation of Low-Tech Indoor Remediation Methods ...

EPA Pesticide Factsheets

Report This study identified, collected, evaluated, and summarized available articles, reports, guidance documents, and other pertinent information related to common housekeeping activities within the United States. This resulted in a summary compendium including relevant information about multiple low-tech cleaning methods from the literature search results. Through discussion and prioritization, an EPA project team, made up of several EPA scientists and emergency responders, focused the information into a list of 14 housekeeping activities for decontamination evaluation testing. These types of activities are collectively referred to as “low-tech” remediation methods because of the comparative simple tools, equipment, and operations involved. Similarly, eight common household surfaces were chosen that were contaminated using three different contamination conditions. Thirty-three combinations of methods and surfaces were chosen for testing under the three contamination conditions for a total of 99 tests.

Menstruation and menstrual symptoms are commonly cited barriers to physical activity in women. The delay or avoidance of menstruation through extended oral-contraceptive (OC) regimens may mitigate these barriers, yet information on menstrual-manipulation practices in young physically active women is sparse. The objective of this study was to investigate prevalence of, and reasons for, menstrual manipulation with OCs in recreationally and competitively active women. One hundred ninety-one recreationally active (self-reported moderate to vigorous physical activity 150-300 min/wk) women (age 23 ± 5 y), 160 subelite recreationally active (self-reported moderate to vigorous physical activity >300 min/wk) women (age 23 ± 5 y), and 108 competitive (state-, national- or international-level) female athletes (age 23 ± 4 y) completed a self-administered questionnaire assessing OC-regimen habits and reasons for manipulation of menstruation. The majority (74%) of OC users reported having deliberately manipulated menstruation at least once during the previous year, with 29% reporting having done so at least 4 times. Prevalence of menstrual manipulation (at least once in the previous year) was not different between competitive athletes, subelite recreationally active women, and recreationally active women (77% vs 74% vs 72%; P > .05). The most cited reasons for manipulating menstruation were special events or holidays (rated by 75% as important/very important), convenience (54%), and sport competition (54%). Menstrual manipulation through extended OC regimens is common practice in recreationally and competitively active young women, for a range of reasons relating to convenience that are not limited to physical activity. This strategy may help reduce hormone-related barriers to exercise participation, thereby positively affecting participation and performance.

To determine the effect of health behavior change counseling (HBCC) on patient activation and the influence of patient activation on rehabilitation engagement, and to identify common barriers to engagement among individuals undergoing surgery for degenerative lumbar spinal stenosis. Prospective clinical trial. Academic medical center. Consecutive lumbar spine surgery patients (N=122) defined in our companion article (Part I) were assigned to a control group (did not receive HBCC, n=59) or HBCC group (received HBCC, n=63). Brief motivational interviewing-based HBCC versus control (significance, P<.05). We assessed patient activation before and after intervention. Rehabilitation engagement was assessed using the physical therapist-reported Hopkins Rehabilitation Engagement Rating Scale and by a ratio of self-reported physical therapy and home exercise completion. Common barriers to rehabilitation engagement were identified through thematic analysis. Patient activation predicted engagement (standardized regression weight, .682; P<.001). Postintervention patient activation was predicted by baseline patient activation (standardized regression weight, .808; P<.001) and receipt of HBCC (standardized regression weight, .444; P<.001). The effect of HBCC on rehabilitation engagement was mediated by patient activation (standardized regression weight, .079; P=.395). One-third of the HBCC group did not show improvement compared with the control group. Thematic analysis identified 3 common barriers to engagement: (1) low self-efficacy because of lack of knowledge and support (62%); (2) anxiety related to fear of movement (57%); and (3) concern about pain management (48%). The influence of HBCC on rehabilitation engagement was mediated by patient activation. Despite improvements in patient activation, one-third of patients reported low rehabilitation engagement. Addressing these barriers should lead to greater improvements in rehabilitation engagement. Copyright © 2015 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

Abstract: Neutron activation of gas samples in a reactor often requires a medium to retain sufficient amounts of the gas for analysis. Charcoal is commonly used to adsorb gas and hold it for activation; however, the amount of activated sodium in the charcoal after irradiation swamps most signals of interest. Neutron activation analysis (NAA) was performed on several commonly available charcoal samples in an effort to determine the activation background. The results for several elements, including the dominant sodium element, are reported. It was found that ECN charcoal had the lowest elemental background, containing sodium at 2.65 ± 0.05 ppm,more » as well as trace levels of copper and tungsten.« less

Fisher, Anna E O; Hague, Theresa A; Clarke, Charlotte L; Naughton, Declan P

2004-10-08

Metal ion chelators widely used in experimental protocols and clinical diagnosis are generally assumed to be inert. We previously reported that the ubiquitous chelator EDTA has high levels of superoxide suppressing activity. Here, we report that the common chelators calcium chelator EGTA and contrast agent EHPG have significant activities in suppressing superoxide levels depending on the nature of metal ion chelated. The most active species is Mn(II)-EGTA which exhibited an IC50 value of 0.19 microM for superoxide destruction. In addition, IC50 values for Mn(II)-EHPG and 2Cu(II)-EGTA were 0.69 and 0.60 microM, respectively. In conclusion, Mn(II) and Cu(II) complexes of the common chelators EGTA and EHPG exhibit considerable superoxide scavenging activities. Caution should be employed in their use in biological systems where superoxide has a key role and they may be useful for the development of catalytic anti-oxidants. Copyright 2004 Elsevier Inc.

A thorough understanding of gender differences in physical activity is critical to effective promotion of active living in older adults. To examine gender and age differences in levels, types and locations of physical activity. Cross-sectional observation. Car-dependent urban and rural neighborhoods in Worcester County, Massachusetts, USA. 111 men and 103 women aged 65 years and older. From 2012 to 2014, participants were queried on type, frequency and location of physical activity. Participants wore an accelerometer for 7 consecutive days. Compared to women, men had a higher mean daily step count (mean (SD) 4385 (2122) men vs. 3671(1723) women, p=0.008). Men reported higher frequencies of any physical activity and moderate-to-vigorous physical activity, and a lower frequency of physical activity inside the home. Mean daily step counts and frequency of physical activity outside the home decreased progressively with age for both men and women. Women had a sharper decline in frequencies of self-reported physical activity. Men had a significant decrease in utilitarian walking, which women did not (p=0.07). Among participants who reported participation in any physical activity (n=190), more women indicated exercising indoors more often (59% vs. 44%, p=0.04). The three most commonly cited locations for physical activity away from home for both genders were streets or sidewalks, shopping malls, and membership-only facilities (e.g., YMCA or YWCA). The most common types of physical activity, performed at least once in a typical month, with over 40% of both genders reporting, included light housework, brisk walking, leisurely walking, and stretching. Levels, types and location preferences of physical activity differed substantially by gender. Levels of physical activity decreased progressively with age, with greater decline among women. Consideration of these gender differences is necessary to improve the effectiveness of active living promotion programs among older adults.

Luciferase reporter gene assays are one of the most common methods for monitoring gene activity. Because of their sensitivity, dynamic range, and lack of endogenous activity, luciferase assays have been particularly useful for functional genomics in cell-based assays, such as RNAi screening. This unit describes delivery of two luciferase reporters with other nucleic acids (siRNA /dsRNA), measurement of the dual luciferase activities, and analysis of data generated. The systematic query of gene function (RNAi) combined with the advances in luminescent technology have made it possible to design powerful whole genome screens to address diverse and significant biological questions.

p53 mutations occur very frequently in human cancer. Besides abrogating the tumour suppressive functions of wild-type p53, many of those mutations also acquire oncogenic gain-of-function activities. Augmentation of proteasome activity is now reported as a common gain-of-function mechanism shared by different p53 mutants, which promotes cancer resistance to proteasome inhibitors.

A molecule that treats multiple age-related diseases would have a major impact on global health and economics. The SIRT1 deacetylase has drawn attention in this regard as a target for drug design. Yet controversy exists around the mechanism of sirtuin-activating compounds (STACs). We found that specific hydrophobic motifs found in SIRT1 substrates such as PGC-1α and FOXO3a facilitate SIRT1 activation by STACs. A single amino acid in SIRT1, Glu(230), located in a structured N-terminal domain, was critical for activation by all previously reported STAC scaffolds and a new class of chemically distinct activators. In primary cells reconstituted with activation-defective SIRT1, the metabolic effects of STACs were blocked. Thus, SIRT1 can be directly activated through an allosteric mechanism common to chemically diverse STACs.

2014-01-01

Purpose Children's physical activity (PA) levels are commonly assessed in pediatric clinical research, but rigorous self-report assessment tools for children are scarce, and computer adaptive test implementations are rare. Our objective was to improve pediatric self-report measures of activity using semi-structured interviews with experts and children for conceptualization of a child-informed framework. Methods Semi-structured interviews were conducted to conceptualize physical activity, sedentary behaviors, and strengthening activities. We performed systematic literature reviews to identify item-level concepts used to assess these 3 domains. Results We developed conceptual frameworks for each domain using words and phrases identified by children as relevant. Conclusions Semi-structured interview methods provide valuable information of children's perspectives and the ways children recall previous activities. Conceptualized domains of physical activity are based on the literature and expert views that also reflect children's experiences and understanding providing a basis for pediatric self-report instruments.

Objective To clarify how participation in leisure activities and exercise by chronic stroke survivors differs before and after a stroke. Methods Sixty chronic stroke survivors receiving community-based rehabilitation services from a health center in Seongnam City were recruited. They completed a questionnaire survey regarding their demographic characteristics and accompanying diseases, and on the status of their leisure activities and exercise. In addition, their level of function (Korean version of Modified Barthel Index score), risk of depression (Beck Depression Inventory), and quality of life (SF-8) were measured. Results After their stroke, most of the respondents had not returned to their pre-stroke levels of leisure activity participation. The reported number of leisure activities declined from a mean of 3.9 activities before stroke to 1.9 activities post-stroke. In addition, many participants became home-bound, sedentary, and non-social after their stroke. The most common barriers to participation in leisure activities were weakness and poor balance, lack of transportation, and cost. The respondents reported a mean daily time spent on exercise of 2.6±1.3 hours. Pain was the most common barrier to exercise participation. Conclusion Chronic stroke survivors need information on leisure activities and appropriate pain management. PMID:25932420

Asthma is a heterogeneous chronic airway disease which may reduce capability for physical activity. In healthy peers, physical activity is influenced by psychosocial and socioeconomic factors. Knowledge about the role of these factors has not been mapped in children and adolescents with asthma. The main objective of this scoping review was to identify psychosocial and socioeconomic factors associated with physical activity level in children and adolescents with asthma in the literature. The specific objectives were to map the instruments used to measure these factors, report on the construction and validation of these instruments, map psychosocial and socioeconomic issues related to physical activity level reported in qualitative studies, and identify gaps in knowledge about the relationship between psychosocial and socioeconomic factors and physical activity level in children and adolescents with asthma. Children and adolescents with asthma aged six to 18 years. Psychosocial and socioeconomic factors related to physical activity level and participation. All physical activity contexts. Quantitative and qualitative primary studies in English, with no date limit. The databases searched included nine major databases for health and sports science, and five databases for unpublished studies. After screening and identification of studies, the reference lists of all identified reports were searched, and forward citation searches were conducted using four databases. The following data were extracted: (a) relevant study characteristics and assessment of physical activity level, (b) instruments used to assess psychosocial and socioeconomic factors, (c) association between physical activity level and these factors, (d) construction and validation of instruments, and (e) psychosocial and socioeconomic issues related to physical activity participation. Twenty-one quantitative and 13 qualitative studies were included. In cross-sectional studies, enjoyment, physical self-concept, self-efficacy, attitudes and beliefs about physical activity and health, psychological distress, health-related quality of life, and social support were more often reported as being correlated with physical activity level. In three studies, the construct validity was assessed by factor analysis and construct reliability tests for the study population. Qualitative studies reported 10 issues related to physical activity participation, and capability and being like peers were most commonly reported. There was no direct evidence that qualitative research informed the development or adjustment of instruments in quantitative studies. Seven psychosocial factors correlated with physical activity level; capability and being like peers were the most commonly reported issues. Reports of the construction and validation of instruments were sparse.

Adolescent Health Risk Behaviors: Parental Concern and Concordance Between Parent and Adolescent Reports.

Gersh, Elon; Richardson, Laura P; Katzman, Katherine; Spielvogle, Heather; Arghira, Adriana Cristina; Zhou, Chuan; McCarty, Carolyn A

We investigated which adolescent health risk behaviors are of concern to parents generally, according to adolescent age, gender, and in the context of perceived risk. We compared adolescent and parent reports of the presence of health-risk behaviors and factors predicting agreement. Three hundred adolescents aged 13 to 18 years (mean, 14.5 years; 52% female) who presenting for well care completed an electronic screening tool used to assess health-risk behaviors. Parents completed parallel measures of their child's behavior and parental concern. Adolescent and parent reports were compared using McNemar test. Hierarchical linear regression was used to examine predictors of agreement. High parental concern was most commonly reported for screen time and diet. When parents identified their adolescent as at-risk, high parental concern was near universal for mental health but less commonly reported for substance use. There were no differences in parental concern according to adolescent gender. Parents of older adolescents expressed more concern regarding physical activity and alcohol. Compared with adolescents, parents were more likely to report risk regarding anxiety, fruit and vegetable consumption, and physical activity, and less likely to report risk regarding screen time, sleep, and marijuana use. Younger adolescent age and higher family relationship quality were predictive of stronger parent-adolescent agreement. Parents in well-care visits commonly have concerns about adolescent lifestyle behaviors. Although parents are more likely to report concern when they know about a behavior, parental concern is not always aligned with parental awareness of risk, particularly for substance use. Parent report of higher prevalence of some risk behaviors suggests their input might assist in risk identification. Copyright © 2017 Academic Pediatric Association. Published by Elsevier Inc.

Why do children think they get discomfort related to daily activities?

PubMed

Coleman, Jemma; Straker, Leon; Ciccarelli, Marina

2009-01-01

Children commonly report musculoskeletal discomfort related to different activities such as computer use, playing electronic games, watching TV, reading, and performing physical and hand intensive activities. Discomfort can result in disability and is a strong predictor of future discomfort in adulthood. Adult beliefs regarding discomfort can affect the level of disability and are modifiable. Children's beliefs regarding discomfort could potentially be modified to minimise disability related to musculoskeletal disorders. The aim of this study was to describe children's beliefs about why they experience musculoskeletal discomfort, both in general and related to specific activities. Eighty eight school children completed questionnaires on frequency and usual duration of nine activities, whether they had felt discomfort and what they believed was the cause of any discomfort in relation to those activities. The most common activity was TV watching, and most activities were performed for 1 hour or shorter. Bad posture and doing too much of a certain activity were the most common beliefs regarding reasons for discomfort. This study shows that children are developing beliefs that tend to reflect scientific knowledge about risk factors. These beliefs could be incorporated into preventative health interventions.

2016-01-01

We describe levels of sexual activity, problems with sexual functioning, and concerns about sexual health among older adults in the English Longitudinal Study of Ageing (ELSA), and associations with age, health, and partnership factors. Specifically, a total of 6,201 core ELSA participants (56 % women) aged 50 to >90 completed a comprehensive Sexual Relationships and Activities questionnaire (SRA-Q) included in ELSA Wave 6 (2012/13). The prevalence of reporting any sexual activity in the last year declined with age, with women less likely than men at all ages to report being sexually active. Poorer health was associated with lower levels of sexual activity and a higher prevalence of problems with sexual functioning, particularly among men. Difficulties most frequently reported by sexually active women related to becoming sexually aroused (32 %) and achieving orgasm (27 %), while for men it was erectile function (39 %). Sexual health concerns most commonly reported by women related to their level of sexual desire (11 %) and frequency of sexual activities (8 %). Among men it was level of sexual desire (15 %) and erectile difficulties (14 %). While the likelihood of reporting sexual health concerns tended to decrease with age in women, the opposite was seen in men. Poor sexual functioning and disagreements with a partner about initiating and/or feeling obligated to have sex were associated with greater concerns about and dissatisfaction with overall sex life. Levels of sexual activity decline with increasing age, although a sizable minority of men and women remain sexually active until the eighth and ninth decades of life. Problems with sexual functioning were relatively common, but overall levels of sexual health concerns were much lower. Sexually active men reported higher levels of concern with their sexual health and sexual dissatisfaction than women at all ages. Older peoples' sexual health should be managed, not just in the context of their age, gender, and general health, but also within their existing sexual relationship.

Background Current methods measuring sports activity after anterior cruciate ligament (ACL) injury are commonly restricted to the most knee-demanding sport, and do not consider participation in multiple sports. We therefore developed an online activity survey to prospectively record monthly participation in all major sports relevant to our patient-group. Objective To assess the reliability, content validity, and concurrent validity of the survey, and evaluate if it provided more complete data on sports participation than a routine activity questionnaire. Methods One hundred and forty-five consecutively included ACL-injured patients were eligible for the reliability study. The retest of the online activity survey was performed two days after the test response had been recorded. A subsample of 88 ACL-reconstructed patients were included in the validity study. The ACL-reconstructed patients completed the online activity survey from the first to the twelfth postoperative month, and a routine activity questionnaire 6 and 12 months postoperatively. Results The online activity survey was highly reliable (κ ranging from 0.81 to 1). It contained all the common sports reported on the routine activity questionnaire. There was substantial agreement between the two methods on return to preinjury main sport (κ = 0.71 and 0.74 at 6 and 12 months postoperatively). The online activity survey revealed that a significantly higher number of patients reported to participate in running, cycling and strength training, and patients reported to participate in a greater number of sports. Conclusion The online activity survey is a highly reliable way of recording detailed changes in sports participation after ACL injury. The findings of this study support the content and concurrent validity of the survey, and suggest that the online activity survey can provide more complete data on sports participation than a routine activity questionnaire.

To evaluate and compare the utility of commonly used outcome measures for assessing disease exacerbation or flare in patients with rheumatoid arthritis (RA). Data from the Dutch Potential Optimalisation of (Expediency) and Effectiveness of Tumor necrosis factor-α blockers (POET) study, in which 462 patients discontinued their tumor necrosis factor-α inhibitor, were used. The ability of different measures to discriminate between those with and without physician-reported flare or medication escalation at the 3-month visit (T2) was evaluated by calculating effect size (ES) statistics. Responsiveness to increased disease activity was compared between measures by standardizing change scores (SCS) from baseline to the 3-month visit. Finally, the incremental validity of individual outcome measures beyond the Simplified Disease Activity Score was evaluated using logistic regression analysis. The SCS were greater for disease activity indices than for any of the individual measures. The 28-joint Disease Activity Score, Clinical Disease Activity Index, and Simplified Disease Activity Index performed similarly. Pain and physician's (PGA) and patient's global assessment (PtGA) of disease activity were the most responsive individual measures. Similar results were obtained for discriminative ability, with greatest ES for disease activity indices followed by pain, PGA, and PtGA. Pain was the only measure to demonstrate incremental validity beyond SDAI in predicting 3-month flare status. These results support the use of composite disease activity indices, patient-reported pain and disease activity, and physician-reported disease activity for measuring disease exacerbation or identifying flares of RA. Physical function, acute-phase response, and the auxiliary measures fatigue, participation, and emotional well-being performed poorly.

Salmonella species cause an estimated 1.2 million infections per year in the United States, making it one of the most commonly reported enteric pathogens. In addition, Salmonella is an important cause of travel-associated diarrhea and enteric fever, a systemic illness commonly associated with Salmonella serotypes Typhi and Paratyphi A. We reviewed cases of Salmonella infection reported to the Centers for Disease Control and Prevention's (CDC) Foodborne Diseases Active Surveillance Network (FoodNet), a sentinel surveillance network, from 2004 to 2008. We compared travelers with Salmonella infection to nontravelers with Salmonella infection with respect to demographics, clinical characteristics, and serotypes. Among 23,712 case-patients with known travel status, 11% had traveled internationally in the 7 days before illness. Travelers with Salmonella infection tended to be older (median age, 30 years) than nontravelers (median age, 24 years; p<0.0001), but were similar with respect to gender. The most common destinations reported were Mexico (38% of travel-associated infections), India (9%), Jamaica (7%), the Dominican Republic (4%), China (3%), and the Bahamas (2%). The proportions of travelers with Salmonella infection hospitalized and with invasive disease were inversely related to the income level of the destination (p<0.0001). The most commonly reported serotypes, regardless of travel status, were Enteritidis (19% of cases), Typhimurium (14%), Newport (9%), and Javiana (5%). Among infections caused by these four serotypes, 22%, 6%, 5%, and 4%, respectively, were associated with travel. A high index of clinical suspicion for Salmonella infection is appropriate when evaluating recent travelers, especially those who visited Africa, Asia, or Latin America.

Physical activity (PA) public health programming has been widely used in Mexico; however, few studies have documented individual and organizational factors that might be used to evaluate their public health impact. The RE-AIM framework is an evaluation tool that examines individual and organizational factors of public health programs. The purpose of this study was to use the RE-AIM framework to determine the degree to which PA programs in Mexico reported individual and organizational factors and to investigate whether reporting differed by the program's funding source. Public health programs promoting PA were systematically identified during 2008-2013 and had to have an active program website. Initial searches produced 23 possible programs with 12 meeting inclusion criteria. A coding sheet was developed to capture behavioral, outcome and RE-AIM indicators from program websites. In addition to targeting PA, five (42%) programs also targeted dietary habits and the most commonly reported outcome was change in body composition (58%). Programs reported an average of 11.1 (±3.9) RE-AIM indicator items (out of 27 total). On average, 45% reported reach indicators, 34% reported efficacy/effectiveness indicators, 60% reported adoption indicators, 40% reported implementation indicators, and 35% reported maintenance indicators. The proportion of RE-AIM indicators reported did not differ significantly for programs that were government supported (M = 10, SD = 3.1) and programs that were partially or wholly privately or corporately supported (M = 12.0, SD = 4.4). While reach and adoption of these programs were most commonly reported, there is a need for stronger evaluation of behavioral and health outcomes before the public health impact of these programs can be established.

Obesity prevention for children with physical disabilities: a scoping review of physical activity and nutrition interventions.

PubMed

McPherson, Amy C; Keith, Rebekah; Swift, Judy A

2014-01-01

Children with disabilities are at higher risk of obesity, engage in less physical activity and report poorer quality dietary habits than their non-disabled peers. This study reviewed current evidence on interventions designed to facilitate weight management and/or weight-related behaviors (i.e. physical activity and/or healthy eating habits) in children with physical disabilities. A scoping review was performed using established methodology. Data from studies meeting specific inclusion criteria were extracted and analyzed using summary statistics, and common characteristics thematically identified. Thirty-four articles were included in the synthesis. No long-term obesity prevention interventions were identified. The majority of research focused upon children with cerebral palsy, and had case study, quasi- or non-experimental designs. All interventions reporting positive outcomes (n = 18) addressed physical activity, with common themes including using motivational strategies for the child and child self-direction. Incremental increases in workload and engaging in strength training for longer than 15 minutes were also effective. Interventions targeting body weight/composition did not report success in the long term. A robust evidence base is lacking for long-lasting obesity interventions for children with physical disabilities. Current research provides some insights into the specific components that should be considered when planning such interventions in the future.

Chiropractic chronic low back pain sufferers and self-report assessment methods. Part II. A reliability study of the Middlesex Hospital Questionnaire and the VAS Disability Scales Questionnaire.

PubMed

Leboeuf, C; Love, A; Crisp, T C

1989-04-01

The subjective complaints of 41 chronic low back pain sufferers attending a chiropractic clinic were assessed twice prior to therapy with a widely used psychological self-report assessment tool, the Middlesex Hospital Questionnaire (MHQ) and a newly developed VAS Disability Scales Questionnaire (DISQ), both of which investigate various aspects of certain basic positions and activities. Reliability was generally acceptable with these two questionnaires. Subjects participating in the study were commonly found to score within the normal range on the MHQ, indicating that psychological disturbance was not a major feature of their presentation. However, mild mood disturbance was commonly reported, and a more sensitive tool may need to be developed for this type of mildly affected chronic low back pain sufferers. The DISQ generally indicated subjects were mildly to moderately affected by their low back trouble and that sitting and leisure activities were the most pain provoking. Recommendations for further development of the disability scale are made.

PHYSICAL ACTIVITY AND THE PELVIC FLOOR

PubMed Central

Nygaard, Ingrid E.; Shaw, Janet M.

2015-01-01

Pelvic floor disorders (PFDs) are common, with one in four U.S. women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review is to summarize studies reporting the association between physical activity and PFDs. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include: Urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this exam finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for women. However, future research is needed to fill the many gaps in our knowledge. Prospective studies are needed in all populations, including potentially vulnerable women, such as those with high genetic risk, levator ani muscle injury, or asymptomatic pelvic organ prolapse, and on women during potentially vulnerable life periods, such as the early postpartum or postoperative periods.

The primary findings of this review include that urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high-intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this examination finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for women. However, future research is needed to fill the many gaps in our knowledge. Prospective studies are needed in all populations, including potentially vulnerable women, such as those with high genetic risk, levator ani muscle injury, or asymptomatic pelvic organ prolapse, and on women during potentially vulnerable life periods, such as the early postpartum or postoperative periods.

The use of pedometers for monitoring physical activity in children and adolescents: measurement considerations.

PubMed

Clemes, Stacy A; Biddle, Stuart J H

2013-02-01

Pedometers are increasingly being used to measure physical activity in children and adolescents. This review provides an overview of common measurement issues relating to their use. Studies addressing the following measurement issues in children/adolescents (aged 3-18 years) were included: pedometer validity and reliability, monitoring period, wear time, reactivity, and data treatment and reporting. Pedometer surveillance studies in children/adolescents (aged: 4-18 years) were also included to enable common measurement protocols to be highlighted. In children > 5 years, pedometers provide a valid and reliable, objective measure of ambulatory activity. Further evidence is required on pedometer validity in preschool children. Across all ages, optimal monitoring frames to detect habitual activity have yet to be determined; most surveillance studies use 7 days. It is recommended that standardized wear time criteria are established for different age groups, and that wear times are reported. As activity varies between weekdays and weekend days, researchers interested in habitual activity should include both types of day in surveillance studies. There is conflicting evidence on the presence of reactivity to pedometers. Pedometers are a suitable tool to objectively assess ambulatory activity in children (> 5 years) and adolescents. This review provides recommendations to enhance the standardization of measurement protocols.

An essential assumption of injury prevention programs is the common cause hypothesis that the causal pathways of near misses and minor injuries are similar to those of major injuries. The rates of near miss, minor injury and major injury of all reported incidents and musculoskeletal incidents (MSIs) were calculated for three health regions using information from a surveillance database and productive hours from payroll data. The relative distribution of individual causes and activities involved in near miss, minor injury and major injury were then compared. For all reported incidents, there were significant differences in the relative distribution of causes for near miss, minor, and major injury. However, the relative distribution of causes and activities involved in minor and major MSIs were similar. The top causes and activities involved were the same across near miss, minor, and major injury. Finding from this study support the use of near miss and minor injury data as potential outcome measures for injury prevention programs. (c) 2008 Wiley-Liss, Inc.

Background Sexually transmitted infections (STIs) are common in adolescents worldwide. Vulnerability to STIs increases with risky sexual practices. This study described the sexual practices, estimated the prevalence of STIs, and identified correlates associated with STIs among participants, enrolled in public high schools, in the District of Panama, Panama. Methods A cross sectional study, using multistage cluster sampling, was conducted among participants, aged 14–18 years, enrolled in public high schools, in the District of Panama, Panama City, Panama, from August to November, 2015. Participants completed a self-administered questionnaire and provided biological samples. The samples of those reporting sexual activity (oral, vaginal, and/or anal intercourse) were tested for STIs. Odds ratios were used to identify correlates of STIs in this population. Results A total of 592 participants were included, of whom, 60.8% reported a history of sexual activity, and 24.4% tested positive for least one STI. STIs were more common in female participants, (33.5%). Compared to those without STIs, higher proportions of those with at least one STI reported ≥3 sexual partners in their lifetime (60.0%) and current sexual activity (76.3%). In the multivariable model, correlates of STI included female participants (Adjusted Odds Ratio (AOR) = 5.8, 95% Confidence Interval (CI) 2.3–14.6) and those who engaged in sexual intercourse with casual partners (AOR = 3.0, 95% CI: 1.2–7.5). Conclusions We report a high STI prevalence among adolescents attending public high schools, in the District of Panama. Reported risky sexual practices were common and correlated with STIs. Female participants and those reporting sexual intercourse with casual partners were more likely test positive for at least one STI. Our study identified a need for effective interventions to curb future infections in this population. PMID:27657700

Anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) injuries and their subsequent reconstructions are common in the general population, but there has been no research regarding ACL or PCL injuries in patients with achondroplasia, the most common skeletal dysplasia. Our goals were to (1) evaluate the prevalence of ACL and PCL injuries in adolescents and adults with achondroplasia, (2) compare this prevalence with that reported for the general population, (3) determine how many patients with ACL or PCL injuries underwent ligament reconstruction as treatment, and (4) determine patient activity levels as they relate to the rate of ACL/PCL injuries and reconstructions. We reviewed medical records of 430 patients with achondroplasia seen in the senior author's clinic from 2002 through 2014. Demographic data were reviewed, as well as any documentation of ACL or PCL injury or reconstruction. We called all 430 patients by telephone, and 148 agreed to participate in our survey, whereas 1 declined. We asked these patients about their history of ACL or PCL injury or reconstruction, as well as current and past physical activity levels. No ACL or PCL injuries were found on chart review. One patient reached by telephone reported an ACL injury that did not require reconstruction. This yielded a theoretical prevalence of 3/430 (0.7%). Of the 148 patients surveyed, 43 (29%) reported low physical activity, 75 (51%) reported moderate physical activity, and 26 (17%) reported high physical activity. There was no significant difference in the rate of ACL injury when stratified by physical activity level (P=0.102). ACL and PCL injuries and reconstructions are extremely rare in patients with achondroplasia, which cannot be completely ascribed to a low level of physical activity. One possible explanation is that patients with achondroplasia, on an average, have a more anterior tibial slope compared with those without achondroplasia, which decreases the force generated within the ACL and may protect against ACL injury. Further research is needed to explore possible causes. Level IV-retrospective review.

Extrarenal perivascular epithelioid cell tumors (PEComas) respond to mTOR inhibition: Clinical and molecular correlates

Perivascular epithelioid cell tumors (PEComas) are a group of rare mesenchymal tumors that typically show both melanocytic and smooth muscle cell features. Some types of PEComa are seen at high frequency in tuberous sclerosis complex (TSC). The TSC1 and TSC2 genes are commonly mutated in both TSC-associated and sporadic PEComas, and mTOR signaling pathway activation is also common in these tumors. Preliminary reports have indicated that the mTOR inhibitors sirolimus and related drugs have activity in some patients with non-TSC-associated PEComa. Here we report on the use of these medications in the treatment of five consecutive patients with extrarenal non-pulmonary PEComas seen at one institution. Three complete responses, one partial response and one case of progression were seen. Molecular studies identified TSC2 aberrations in four of these patients, and TFE3 translocation was excluded in the resistant case. A review of all published cases as well as those reported here indicates that partial or complete response was seen in 6 of 11 PEComas, with 5 of the 6 having a complete response. These findings highlight the consistent though incomplete activity of mTOR inhibitors in the treatment of PEComas. PMID:22927055

Chemotherapy is the preferred and most common treatment for cancer in clinical practice. An increasing number of researchers all over the world are focusing on natural medicines to find new antitumor drugs, and several reports have shown that Camellia nitidissima (C. nitidis-sima) Chi could reduce blood-lipid, decrease blood pressure, resist oxidation, prevent carcinogenesis and inhibit tumors. Therefore, the pharmacodynamics of the chemical constituents in C. nitidissima need to be investigated further. In the present study, 16 chemical constituents were isolated from the leaves of C. nitidissima, of which 6 compounds are reported to be found in this plant for the first time. Furthermore, all these phytochemicals were screened for antitumor activity on 4 common cancer cell lines, while compound 3, one oleanane-type triterpene, exhibited the most potential antitumor effects. Interestingly, to our knowledge, this was the first report that compound 3 inhibits cancer cells. Compound 3 inhibited EGFR-mutant lung cancer cell line, NCI-H1975 via apoptosis effect, with an IC50 of 13.37±2.05 µM at 48 h. Based on the data, compound 3 showed potential for antitumor drug development, suggesting the scientific basis for the antitumor activity of C. nitidissima. PMID:29484370

To help understand suicide among soldiers, we compared suicide events between active duty U.S. Army versus civilian decedents to identify differences and inform military prevention efforts. We linked 141 Army suicide records from 2005 to 2010 to National Violent Death Reporting System (NVDRS) data. We described the decedents’ military background and compared their precipitators of death captured in NVDRS to those of demographically matched civilian suicide decedents. Both groups commonly had mental health and intimate partner precipitating circumstances, but soldier decedents less commonly disclosed suicide intent. PMID:25093259

2007-05-01

This paper examines the prevalence, precursors, and consequences of unwanted marital sex activities in a national sample of 1,127 married urban Chinese women aged 20-64. During the lifetime of their current marriage, 32% reported ever experiencing unwanted spousal intercourse, with about one-fifth reporting that this unwanted intercourse ever involved force. Reports for the past year were 21% unwanted intercourse, 22% unwanted sex act(s), and 72% sex only to please the husband. The major risk factors for these activities were poor relationship quality (hitting, lack of daily intimacy and foreplay, and husband insensitivity to wife's sexual needs); a woman's negative attitudes towards sex, and weak bargaining position (low income share, husband's family of superior economic status, and no additional adults in home). In addition, unwanted activity was more common when women reported sexual dysfunctions (dryness, pain, low arousal, inorgasmia), were more educated, and had more permissive sex attitudes. Net of feedback effects, unwanted sexual activity diminished women's psychological well-being.

Background: Neck pain is common, but few studies have used qualitative methods to describe it. Purpose: To describe the quality, distribution and behavior of neck pain. Methods: Sixteen people (15 females; mean age = 33 years (range = 20-69)) with neck pain >3 months were interviewed using a semi-structured guide. Interview data were recorded and transcribed verbatim. Descriptive content analysis was performed by two authors. Participants then completed an electronic descriptive pain tool, placing icons (word and icon descriptors to describe quality) on anatomic diagrams to identify location of pain, and intensity ratings at each location. This data was triangulated with interviews. Results: Aching pain and stiffness in the posterior neck and shoulder region were the most common pain complaints. All patients reported more than one pain quality. Associated headache was common (11/16 people); but varied in location and pain quality; 13/16 reported upper extremity symptoms. Neuropathic characteristics (burning) or sensory disturbance (numbness/tingling) occurred in some patients, but were less common. Activities that involved lifting/carrying and psychological stress were factors reported as exacerbating pain. Physical activity was valued as essential to function, but also instigated exacerbations. Concordance between the structured pain tool and interviews enhanced trustworthiness of our results. Integrating qualitative findings with a previous classification system derived a 7-axis neck pain classification: source/context, sample subgroup, distribution, duration, episode pattern, pain/symptom severity, disability/participation restriction. Conclusions: Qualitative assessment and classification should consider the multiple dimensions of neck pain. PMID:28217199

Reporter gene assays (RGAs) are commonly used to measure biological pathway modulation by small molecules. Understanding how such compounds interact with the reporter enzyme is critical to accurately interpret RGA results. To improve our understanding of reporter enzymes and to develop optimal RGA systems, we investigated eight reporter enzymes differing in brightness, emission spectrum, stability, and substrate requirements. These included common reporter enzymes such as firefly luciferase (Photinus pyralis), Renilla reniformis luciferase, and β-lactamase, as well as mutated forms of R. reniformis luciferase emitting either blue- or green-shifted luminescence, a red-light emitting form of Luciola cruciata firefly luciferase, a mutated form of Gaussia princeps luciferase, and a proprietary luciferase termed "NanoLuc" derived from the luminescent sea shrimp Oplophorus gracilirostris. To determine hit rates and structure-activity relationships, we screened a collection of 42,460 PubChem compounds at 10 μM using purified enzyme preparations. We then compared hit rates and chemotypes of actives for each enzyme. The hit rates ranged from <0.1% for β-lactamase to as high as 10% for mutated forms of Renilla luciferase. Related luciferases such as Renilla luciferase mutants showed high degrees of inhibitor overlap (40-70%), while unrelated luciferases such as firefly luciferases, Gaussia luciferase, and NanoLuc showed <10% overlap. Examination of representative inhibitors in cell-based assays revealed that inhibitor-based enzyme stabilization can lead to increases in bioluminescent signal for firefly luciferase, Renilla luciferase, and NanoLuc, with shorter half-life reporters showing increased activation responses. From this study we suggest strategies to improve the construction and interpretation of assays employing these reporter enzymes.

Badminton is a sport that requires a lot of over-shoulder motion, with the shoulder in abduction/external rotation. This questionnaire study on 188 international top-level badminton players during the World Mixed Team Championships showed that previous or present shoulder pain on the dominant side was reported by 52% of the players. Previous shoulder pain was reported by 37% of the players and on-going shoulder pain by 20% of the players. There were no significant differences in the prevalence of shoulder pain between men and women. The majority of the shoulder pain had started gradually. The pain was usually associated with shoulder activity, and stiffness was a common, associated symptom. Furthermore, the shoulder pain was associated with consequences such as sleeping disturbances, changes in training and competition habits, and it also affected activities of daily living. The majority of the players had sought medical advice and had been given different kinds of treatment. The study showed that shoulder pain is a common and significant problem in world-class badminton players, and the consequences are most likely of importance for their training and playing capacity.

To provide data about the sexual histories of a large sample of lesbians and bisexual women, to inform those who provide health care or carry out research with women who may be sexually active with other women. Cross sectional survey. 803 lesbians and bisexual women attending, as new patients, lesbian sexual health clinics, and 415 lesbians and bisexual women from a community sample. Self reported sexual history and sexual practice with both male and female partners. 98% of the whole sample gave a history of sexual activity with women, 83% within the past year, with a median of one female partner in that year. 85% of the sample reported sexual activity with men; for most (70%) this was 4 or more years ago. First sexual experience tended to be with a man (median 18 years old), with first sexual experience with a woman a few years later (median 21 years). Oral sex, vaginal penetration with fingers, and mutual masturbation were the most commonly reported sexual practices between women. Vaginal penetration with penis or fingers and mutual masturbation were the most commonly reported sexual activities with men. These data from the largest UK survey of sexual behaviour between women to date demonstrate that lesbians and bisexual women may have varied sexual histories with both male and female partners. A non-judgmental manner and careful sexual history taking without making assumptions should help clinicians to avoid misunderstandings, and to offer appropriate sexual health advice to lesbians and bisexual women.

Monitoring clinical outcome in persons with haemophilia (PWH) is essential in order to provide optimal treatment for individual patients and compare effectiveness of treatment strategies. Experience with measurement of activities and participation in haemophilia is limited and consensus on preferred tools is lacking. The aim of this study was to give a comprehensive overview of the measurement properties of a selection of commonly used tools developed to assess activities and participation in PWH. Electronic databases were searched for articles that reported on reliability, validity or responsiveness of predetermined measurement tools (5 self-reported and 4 performance based measurement tools). Methodological quality of the studies was assessed according to the COSMIN checklist. Best evidence synthesis was used to summarize evidence on the measurement properties. The search resulted in 3453 unique hits. Forty-two articles were included. The self-reported Haemophilia Acitivity List (HAL), Pediatric HAL (PedHAL) and the performance based Functional Independence Score in Haemophilia (FISH) were studied most extensively. Methodological quality of the studies was limited. Measurement error, cross-cultural validity and responsiveness have been insufficiently evaluated. Albeit based on limited evidence, the measurement properties of the PedHAL, HAL and FISH are currently considered most satisfactory. Further research needs to focus on measurement error, responsiveness, interpretability and cross-cultural validity of the self-reported tools and validity of performance based tools which are able to assess limitations in sports and leisure activities. © 2018 The Authors.

Aberrant activation of Akt is a common finding in adult malignant gliomas, resulting in most cases from mutations or deletions involving PTEN, which allows constitutive Akt phosphorylation. In contrast, we have previously reported that pediatric malignant gliomas, which are morphologically similar to lesions arising in adults, have a substantially lower incidence of genomic alterations of PTEN. The objective of this study was to determine whether Akt activation was also an uncommon finding in childhood malignant gliomas and whether this feature was associated with survival. To address this issue, we examined the frequency of Akt activation, determined by overexpression of the activated phosphorylated form of Akt (Se(473)) on immunohistochemical analysis, in a series of 53 childhood malignant gliomas obtained from newly diagnosed patients treated on the Children's Oncology Group ACNS0126 and 0423 studies. The relationship between Akt activation and p53 overexpression, MIB1 labeling, and tumor histology was evaluated. The association between Akt activation and survival was also assessed. Overexpression of activated Akt was observed in 42 of 53 tumors, far in excess of the frequency of PTEN mutations we have previously observed. There was no association between Akt activation and either histology, p53 overexpression, or MIB1 proliferation indices. Although tumors that lacked Akt overexpression had a trend toward more favorable event-free survival and overall survival (p = 0.06), this association reflected that non-overexpressing tumors were significantly more likely to have undergone extensive tumor removal, which was independently associated with outcome. Activation of Akt is a common finding in pediatric malignant gliomas, although it remains uncertain whether this is an independent adverse prognostic factor. In view of the frequency of Akt activation, the evaluation of molecularly targeted therapies that inhibit this pathway warrants consideration for these tumors.

Lyme disease is the most commonly reported vectorborne disease in the United States. The objective of our study was to identify patterns of Lyme disease reporting after multistate inclusion to mitigate potential border effects. County-level human Lyme disease surveillance data were obtained from Kentucky, Maryland, Ohio, Pennsylvania, Virginia, and West Virginia state health departments. Rate smoothing and Local Moran's I was performed to identify clusters of reporting activity and identify spatial outliers. A logistic generalized estimating equation was performed to identify significant associations in disease clustering over time. Resulting analyses identified statistically significant (P=0.05) clusters of high reporting activity and trends over time. High reporting activity aggregated near border counties in high incidence states, while low reporting aggregated near shared county borders in non-high incidence states. Findings highlight the need for exploratory surveillance approaches to describe the extent to which state level reporting affects accurate estimation of Lyme disease progression.

Tew, Garry A; Jones, Katherine; Mikocka-Walus, Antonina

2016-12-01

Limited evidence suggests that physical activity has beneficial effects in people with inflammatory bowel disease (IBD). This study aimed to determine the physical activity habits of adults with IBD, the limitations to physical activity they experience because of their disease, and the extent to which their physical activity is affected by various demographic, clinical, and psychological factors. Data were collected on 859 adult participants (52% with Crohn's disease, 75% women) through an online survey conducted between May and June 2016. Measures included physical activity (International Physical Activity Questionnaire), psychological symptoms (Hospital Anxiety and Depression Scale), fatigue (subitems of IBD fatigue scale), exercise perceptions (Exercise Benefits/Barriers Scale), and disease activity. Regression analyses were used to identify predictors of physical activity. Only 17% of respondents were categorized as "high active." Self-reported physical activity levels decreased, and fatigue and psychological scores increased, with increasing disease activity. Walking was the most common activity performed (57% of respondents) and running/jogging the most commonly avoided (34%). Many participants (n = 677) reported that IBD limited their physical activity, for reasons including abdominal/joint pain (70%), fatigue/tiredness (69%), disease flare-up (63%), and increased toilet urgency (61%). Physical activity was independently associated with depression, disease activity, and perceived barriers to exercise in people with Crohn's disease, and depression and age in people with ulcerative or indeterminate colitis (all P ≤ 0.038). This survey highlights several important factors that should be considered by designers of future physical activity interventions for people with IBD.

Active school transport (AST), school travel using an active mode like walking, may be important to children's overall physical activity. A "school travel plan" (STP) documents a school's transport characteristics and provides an action plan to address school and neighborhood barriers to AST. We conducted a pilot STP intervention at 12 schools in 4 Canadian provinces. Facilitators and school personnel created and implemented AST action plans. Parent's self-reports (N = 1489) were the basis for evaluating the intervention. A content analysis identified type, frequency, and perceived success of initiatives. School travel plans emphasized education and promotion, and AST activities and events. Capital improvement projects were more common at schools in older suburban neighborhoods, whereas enforcement was more common at schools in newer suburban neighborhoods. Rates of active transportation increased from 43.8% to 45.9%. At follow-up, 13.3% of households reported less driving. Parents/caregivers cited weather, convenience, and trip chaining as primary reasons for continued driving. The STP process may facilitate changes to patterns of school travel. An STP can expand a school's capacity to address transportation issues through mobilization of diverse community resources. Future STP initiatives may benefit from addressing convenience, safety through enforcement, and by examining how schools can be supported in implementing infrastructure improvements. © 2011, American School Health Association.

Chelatable trace zinc causes low, irreproducible KDAC8 activity.

Toro, Tasha B; Edenfield, Samantha A; Hylton, Brandon J; Watt, Terry J

2018-01-01

Acetylation is an important regulatory mechanism in cells, and emphasis is being placed on identifying substrates and small molecule modulators of this post-translational modification. However, the reported in vitro activity of the lysine deacetylase KDAC8 is inconsistent across experimental setups, even with the same substrate, complicating progress in the field. We detected trace levels of zinc, a known inhibitor of KDAC8 when present in excess, even in high-quality buffer reagents, at concentrations that are sufficient to significantly inhibit the enzyme under common reaction conditions. We hypothesized that trace zinc in solution could account for the observed variability in KDAC8 activity. We demonstrate that addition of chelators, including BSA, EDTA, and citrate, and/or the use of a phosphate-based buffer instead of the more common tris-based buffer, eliminates the inhibition from low levels of zinc as well as the dependence of specific activity on enzyme concentration. This results in high KDAC8 activity that is consistent across buffer systems, even using low concentrations of enzyme. We report conditions that are suitable for several assays to increase both enzyme activity and reproducibility. Our results have significant implications for approaches used to identify substrates and small molecule modulators of KDAC8 and interpretation of existing data. Copyright © 2017 Elsevier Inc.

Infectious mononucleosis and the spleen.

PubMed

Kinderknecht, James J

2002-04-01

Infectious mononucleosis is an extremely common problem in the athletic population. "Mono" occurs in 3% of college students. Diagnosing infectious mononucleosis requires an understanding of the clinical features such as fever, lymphadenopathy, pharyngitis, and splenomegaly, as well as laboratory findings. The time at which these clinical features and laboratory abnormalities develop is also important to understand. Splenomegaly is common, but splenic rupture is very rare. Whether an athlete may return to activity usually relates to the presence of splenomegaly and the duration of the illness. Splenic rupture has not been reported after an individual has been ill for more than 3 weeks. This article provides an overview of infectious mononucleosis. The most common complications are reviewed and the management of these problems discussed. A practical approach to determining when an athlete may return to activity is presented.

The benefits of physical activity for reducing obesity and related chronic diseases are well known. The need for more family-based interventions to increase physical activity is frequently cited in the literature; however, little is known about if and how families are physically active together, and what factors might influence family-based participation in regular physical activity. This study examined the types of activities (physical and sedentary) engaged in as a family and explored parents' perceptions of the importance, frequency, nature and barriers to family physical activity. Semi-structured telephone interviews were conducted with 30 parents (26 female, four male) of 10- to 11-year-old schoolchildren who attended either low, middle or high socio-economic status schools in Bristol, UK. Interviews were transcribed verbatim, anonymized and analysed using conventional content analysis. The majority of parents rated family engagement in physical activity as important, and identified benefits such as increased parent-child communication, spending time together, enjoyment, enhanced mental health, weight control and physical fitness. Despite these benefits most parents reported their families did little or no physical activity together as a family unit during the week, and any activities performed together were usually sedentary in nature. They reported increased family physical activity on the weekends but rarely including the full family unit simultaneously. Parents in two-parent households commonly paired off with one or more children because of complexities of schedules. Commonly reported barriers were busy lifestyles, diverse ages and interests of children and adults, bad weather, and lack of access to facilities, transportation and money to support activities. Family-based interventions might be more effective if they are designed to accommodate the complex demands and needs of two-parent and single-parent families and provide affordable, diverse activities appealing to a wide range of interests.

Splenic rupture in infectious mononucleosis: A systematic review of published case reports.

PubMed

Bartlett, A; Williams, R; Hilton, M

2016-03-01

Infectious mononucleosis (IM) is a common viral illness that predominantly causes sore throat, fever and cervical lymphadenopathy in adolescents and young adults. Although usually a benign, self-limiting disease, it is associated with a small risk of splenic rupture, which can be life-threatening. It is common practice therefore to advise avoiding vigorous physical activity for at least 4-6 weeks, however this is not based on controlled trials or national guidelines. We reviewed published case reports of splenic rupture occurring in the context of IM in an attempt to ascertain common factors that may predict who is at risk. A search of MEDLINE and EMBASE databases was performed for case reports or series published between 1984 and 2014. In total, 52 articles or abstracts reported 85 cases. Data was extracted and compiled into a Microsoft Excel(®) spreadsheet. The average patient age was 22 years, the majority (70%) being male. The average time between onset of IM symptoms and splenic rupture was 14 days, with a range up to 8 weeks. There was a preceding history of trauma reported in only 14%. Abdominal pain was the commonest presenting complaint of splenic rupture, being present in 88%. 32% were successfully managed non-operatively, whereas 67% underwent splenectomy. Overall mortality was 9%. From our data, it appears that men under 30 within 4 weeks of symptom onset are at highest risk of splenic rupture, therefore particular vigilance in this group is required. As cases have occurred up to 8 weeks after the onset of illness, we would recommend avoidance of sports, heavy lifting and vigorous activity for 8 weeks. Should the patient wish to return to high risk activities prior to this, an USS should be performed to ensure resolution of splenomegaly. The majority of cases reviewed had no preceding trauma, although previous studies have suggested this may be so minor as to go unnoticed by the patient. It is therefore prudent to warn patients about the symptoms of splenic rupture to ensure prompt presentation and minimise treatment delay rather than focusing purely on activity limitation.

Evidence on cultural differences in prevalence and impact of common chronic pain conditions, comparing individuals with temporomandibular disorders (TMD) versus individuals without TMD, is limited. The aim was to assess cross-cultural comorbid pain conditions in women with chronic TMD pain. Consecutive women patients (n = 122) with the index condition of chronic TMD pain diagnosed per the research diagnostic criteria for TMD and TMD-free controls (n = 121) matched for age were recruited in Saudi Arabia, Italy and Sweden. Self-report questionnaires assessed back, chest, stomach and head pain for prevalence, pain intensity and interference with daily activities. Logistic regression was used for binary variables, and ancova was used for parametric data analysis, adjusting for age and education. Back pain was the only comorbid condition with a different prevalence across cultures; Swedes reported a lower prevalence compared to Saudis (P < 0·01). Saudis reported higher prevalence of work reduced >50% due to back pain compared to Italians or Swedes (P < 0·01). Headache was the most common comorbid condition in all three cultures. The total number of comorbid conditions did not differ cross-culturally but were reported more by TMD-pain cases than TMD-free controls (P < 0·01). For both back and head pain, higher average pain intensities (P < 0·01) and interference with daily activities (P < 0·01) were reported by TMD-pain cases, compared to TMD-free controls. Among TMD-pain cases, Italians reported the highest pain-related disability (P < 0·01). Culture influences the associated comorbidity of common pain conditions. The cultural influence on pain expression is reflected in different patterns of physical representation. © 2017 John Wiley & Sons Ltd.

Parasites and cancers: parasite antigens as possible targets for cancer immunotherapy.

An adverse relationship between some parasite infections and cancer in the human population has been reported by different research groups. Anticancer activity of some parasites such as Trypanosoma cruzi, Toxoplasma gondii, Toxocara canis, Acantamoeba castellani and Plasmodium yoelii has been shown in experimental animals. Moreover, it has been shown that cancer-associated mucin-type O-glycan compositions are made by parasites, therefore cancers and parasites have common antigens. In this report anticancer activities of some parasites have been reviewed and the possible mechanisms of these actions have also been discussed.

Since 2007, all Canadian medical schools have had at least one established student-led public health interest group (PHIG). The Association of Faculties of Medicine of Canada (AFMC), the Public Health Task Group, and the Public Health Agency of Canada (PHAC) have supported these PHIGs. The authors describe the activities and structure of PHIGs in Canada from 2007 to 2011, plus the extent to which PHIGs met the objectives set out for them by the AFMC Public Health Task Group. Using a standardized template, the authors analyzed funding applications and reports that PHIG executives submitted to the AFMC from 2007 through 2011. The authors created activity categories and collected simple counts of activities within categories. They then used these data to assess how successfully PHIGs have been able to meet their objectives. Fifty-two funding applications, 50 interim reports, and 48 final reports were available for analysis. All 17 Canadian medical schools had at least one established PHIG between 2007 and 2011, and 9 schools (53%) applied for PHIG funding in all four years. Academic activities such as lectures, seminars, and workshops were the most common activities conducted by PHIGs, followed by career exploration and networking. This study found that the AFMC, with funding support from PHAC, was instrumental in initiating PHIGs in 82% (n = 14) of Canadian medical schools. With consistent funding, national networking opportunities, and a common operating structure, PHIGs have been able to accomplish AFMC's objectives for increasing public health awareness amongst medical students.

To assess the frequency of use of different treatments and pain management strategies and their perceived helpfulness in male patients with pelvic pain. Approximately 1 month after a health maintenance organization visit for pelvic pain, 286 men (mean age 46.7 years) completed telephone interviews about their symptoms and treatments and pain management strategies used in the past year. Participants rated the helpfulness of each treatment and strategy used on 0 to 10 scales. Even though men with identified bacterial etiology were excluded from the study, antibiotic medication was the most commonly reported treatment (67% of patients) and rated as the second most helpful treatment [mean (SD)=6.3 (3.6)]. Opiates were rated as the most helpful treatment on average [mean (SD)=7.9 (2.1)], but were used by only 12% of patients. Substantial minorities of patients reported several behaviors as helpful, including urinating (reported as helpful by 26%), taking warm baths (23%), and drinking water (23%), although patterns of effects differed for men with versus without urinary symptoms. Activities most commonly reported as worsening symptoms were sitting (42%), walking/jogging (27%), and sexual activity (25%). Patients with male pelvic pain syndrome are commonly prescribed antibiotics, which they perceive as moderately helpful, despite the lack of scientific evidence of efficacy. Clinicians may find it useful to support patient use of safe, inexpensive, self-management approaches, especially warm baths, increased water intake, and avoidance of prolonged sitting.

ABSTRACT Introduction Benign prostatic hyperplasia (BPH) and its associated lower urinary tract symptoms (LUTS), including nocturia, are extremely common among middle- and older-age American men. Although studies on physical activity (PA) and prevalent BPH-related outcomes suggest that PA may protect against the development of this common condition, only a few studies have examined the relation between PA and incident BPH-related outcomes and LUTS with mixed findings. In addition, although nocturia is the most commonly reported and most bothersome LUTS in men with or without evidence of BPH, few studies have examined the association of PA and nocturia independent of BPH. The purpose of this analysis was to examine the association of PA with BPH-related outcomes and nocturia in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening trial. Methods We examined this association with both prevalent (n = 28,404) and incident (n = 4710) BPH-related outcomes (measured by self-report of physician diagnosis, BPH surgery, finasteride use, and clinical indicators) and nocturia. Poisson regression with robust variance was used to calculate prevalence ratios and relative risks. Results PA was weakly positively associated with several prevalent BPH-related outcomes and was strongly inversely associated with prevalent nocturia. In incident analyses, PA was only associated with nocturia. Men who were active ≥1 h·wk−1 were 13% less likely (95% confidence interval, 2%–22%) to report nocturia and 34% less likely (95% confidence interval, 15%–49%) to report severe nocturia as compared with men who reported no PA. The associations were similar for men with and without additional BPH-related outcomes, except for prevalent nocturia, where the association was stronger for men without other BPH-related outcomes. Conclusions Combined with other management strategies, PA may provide a strategy for the management of BPH-related outcomes, particularly nocturia. PMID:25010403

Natural gas extraction activities, including the use of horizontal drilling and hydraulic fracturing, may pose potential health risks to both human and animal populations in close proximity to sites of extraction activity. Because animals may have increased exposure to contaminated water and air as well as increased susceptibility to contaminant exposures compared to nearby humans, animal disease events in communities living near natural gas extraction may provide "sentinel" information useful for human health risk assessment. Community health evaluations as well as health impact assessments (HIAs) of natural gas exploration should therefore consider the inclusion of animal health metrics in their assessment process. We report on a community environmental health survey conducted in an area of active natural gas drilling, which included the collection of health data on 2452 companion and backyard animals residing in 157 randomly-selected households of Washington County, Pennsylvania (USA). There were a total of 127 reported health conditions, most commonly among dogs. When reports from all animals were considered, there were no significant associations between reported health condition and household proximity to natural gas wells. When dogs were analyzed separately, we found an elevated risk of 'any' reported health condition in households less than 1km from the nearest gas well (OR = 3.2, 95% CI 1.07-9.7), with dermal conditions being the most common of canine disorders. While these results should be considered hypothesis generating and preliminary, they suggest value in ongoing assessments of pet dogs as well as other animals to better elucidate the health impacts of natural gas extraction on nearby communities.

Physical activity improves health outcomes in colorectal cancer (CRC) survivors, but participation rates are low. One understudied strategy for increasing physical activity in CRC survivors may be sport participation. Here, we report the sport participation rate, sport preferences, and correlates of sport participation among CRC survivors. A provincial, population-based mailed survey of CRC survivors in Alberta, Canada was performed and included measures of sport participation, sport preferences, sport benefits and barriers, and medical and demographic variables. A total of 600 CRC survivors completed the survey (34 % response rate). Almost a quarter (23.0 %) of CRC survivors reported participating in a sport in the past month, with the most common sport being golf (58.7 %). In multivariate regression analysis, 33.0 % (p = 0.001) of the variance in sport participation was explained by being male (β = 0.12; p = 0.006), in better general health (β = 0.12; p = 0.006), and ≥ 5 years post-diagnosis (β = 0.09; p = 0.031). The most common barriers to sport participation were time, age/agility, and no interest/dislike of sports. The most common anticipated benefits of sport participation were improved physical fitness, meeting people, and improved health. Over half (57.2 %) of CRC survivors were possibly interested in learning about sport participation opportunities. Promotion of sport participation may be a potentially fruitful strategy for increasing physical activity in CRC survivors.

Sleep quality, fatigue and physical activity following a cancer diagnosis.

Research on physical activity for cancer survivors suggests a relationship with improved quality of life. The aim of this study was to explore if there was also a relationship of physical activity with sleep difficulties and fatigue, common effects of cancer and its treatments. Recruitment was by posters and flyers in medical waiting rooms and by letter of invitation. Thirty-two breast and 59 prostate cancer survivors completed the questionnaire. Poor sleep quality was reported by 57.8%. A greater proportion of breast cancer (36.7%) than prostate cancer survivors (15.5%) reported poor sleep latency, and sleep disturbance (48.4% vs. 17.2%). The mean minutes of moderate physical activity was lower among participants reporting poor sleep quality [F(1,89) = 11.36, P < 0.001]. A greater proportion of breast cancer (65.7%) than prostate cancer survivors (43.1%) reported high fatigue. Participants who reported no physical activity had significantly greater fatigue (M = 31) than those reporting high physical activity levels (M = 42). While at an early stage of research, results are suggestive of a relationship of physical activity with sleep problems among cancer survivors. Findings have implications for improving quality of life as poor sleep was associated with greater fatigue and regular physical activity shows promise as an aid to alleviating these problems. © 2009 The Authors.

Hygromycin B (Hy) resistance, encoded by the prokaryotic gene hph, is commonly used as a dominant selectable marker for gene transfer experiments in mammalian cells. We describe a simple, quantitative dot-blot assay for measuring the activity in crude mammalian cell extracts of Hy phosphotransferase, the product of the hph gene. The assay shows no cross interference with substrates for neomycin phosphotransferase II, the product of the commonly used marker gene neo; hph and neo may thus be useful as a set of two non-interfering selectable marker and reporter genes for gene transfer experiments in mammalian cells.

Posterior Cruciate Ligament Injuries Associated With Military Survival Swim Training.

Crowell, Michael S; Mason, John S; Posner, Matthew A; Haley, Chad A

2017-07-01

Posterior cruciate ligament (PCL) injuries are relatively common injuries associated with athletic activities and high-energy trauma. Posterolateral corner (PLC) injuries frequently accompany injury to the PCL. Diagnosis can be challenging and requires a comprehensive history and physical examination. Patients frequently report vague, nonspecific symptoms and the mechanism of injury is often useful in localizing injured structures. Two of the more common mechanisms for PCL injury include a direct blow to the proximal anterior tibia with the knee flexed, as well as a significant knee hyperextension injury. With a PCL tear, patients rarely describe an audible "pop" that is commonly reported in ACL injuries. On physical exam, a frequent finding in PCL tears is a loss of 10 to 20° of knee flexion. Although the most common clinical tests for PCL tears include the posterior drawer test, the posterior sag sign, and the quadriceps active test, there is a lack of high-quality diagnostic accuracy studies. Two cases of U.S. Military Academy Cadets who sustained PCL injuries while removing combat boots during military survival swim training are presented. The results of the clinical examination are accompanied by magnetic resonance imaging results and intraoperative arthroscopic images to highlight key findings. Both patients were evaluated and diagnosed with PCL injures within 10 days of their injuries. Each reported feeling/hearing a "pop," which is atypical in PCL tears. Both patients demonstrated a lack of active and passive knee flexion, which is a commonly reported impairment. One patient was managed nonsurgically with physical therapy and eventually returned to full duty without limitations 9 months after his injury. The other patient, who sustained a combined PCL-PLC injury, underwent a PCL reconstruction and PLC repair and reconstruction 8 weeks after his injury. He returned all training, with the exception of contact/collision sports, 9 months after surgery. Both patient's rehabilitation programs consisted of a progression of exercises to improve range of motion, muscle strength/endurance, motor control, and muscular power. Military and sports medicine professionals should be aware of the potential for PCL injury with this unusual, and previously unreported, mechanism of injury during survival swim training. Prompt diagnosis and appropriate treatment is essential to prevent long-term disability. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

Hospital evidence-based practice centers (EPCs) synthesize and disseminate evidence locally, but their impact on institutional decision making is unclear. To assess the evidence synthesis activities and impact of a hospital EPC serving a large academic healthcare system. Descriptive analysis of the EPC's database of rapid systematic reviews since EPC inception (July 2006-June 2014), and survey of report requestors from the EPC's last 4 fiscal years. Descriptive analyses examined requestor and report characteristics; questionnaire examined report usability, impact, and requestor satisfaction (higher scores on 5-point Likert scales reflected greater agreement). The EPC completed 249 evidence reviews since inception. The most common requestors were clinical departments (29%, n = 72), chief medical officers (19%, n = 47), and purchasing committees (14%, n = 35). The most common technologies reviewed were drugs (24%, n = 60), devices (19%, n = 48), and care processes (12%, n = 31). Mean report completion time was 70 days. Thirty reports (12%) informed computerized decision support interventions. More than half of reports (56%, n = 139) were completed in the last 4 fiscal years for 65 requestors. Of the 64 eligible participants, 46 responded (72%). Requestors were satisfied with the report (mean = 4.4), and agreed it was delivered promptly (mean = 4.4), answered the questions posed (mean = 4.3), and informed their final decision (mean = 4.1). This is the first examination of evidence synthesis activities by a hospital EPC in the United States. Our findings suggest hospital EPCs can efficiently synthesize and disseminate evidence addressing a range of clinical topics for diverse stakeholders, and can influence local decision making. © 2015 Society of Hospital Medicine.

2009-01-01

We performed semistructured interviews with 30 family members of patients with advanced dementia to identify the factors that facilitate or hinder advance planning by persons with dementia. All interviews were analyzed using qualitative data analysis techniques. The majority (77%) of family members reported that their relative had some form of written advance directive, and at least half reported previous discussions about health care preferences (57%), living situation or placement issues (50%), and finances or estate planning (60%) with the patient. Family members reported some themes that prompted planning and others that were barriers to planning. Events that most often triggered planning were medical, living situation, or financial issues associated with a friend or family member of the patient (57%). Barriers to planning included both passive and active avoidance. The most common form of passive avoidance was not realizing the importance of planning until it was too late to have the discussion (63%). The most common form of active avoidance was avoiding the discussion (53%). These data suggest potentially remediable strategies to address barriers to advance planning discussions. PMID:18580595

Iconic memory and spatial attention are often considered separately, but they may have functional similarities. Here we provide functional magnetic resonance imaging evidence for some common underlying neural effects. Subjects judged three visual stimuli in one hemifield of a bilateral array comprising six stimuli. The relevant hemifield for partial report was indicated by an auditory cue, administered either before the visual array (precue, spatial attention) or shortly after the array (postcue, iconic memory). Pre- and postcues led to similar activity modulations in lateral occipital cortex contralateral to the cued side. This finding indicates that readout from iconic memory can have some neural effects similar to those of spatial attention. We also found common bilateral activation of a fronto-parietal network for postcue and precue trials. These neuroimaging data suggest that some common neural mechanisms underlie selective spatial attention and readout from iconic memory. Some differences were also found; compared with precues, postcues led to higher activity in the right middle frontal gyrus.

Safety of Sports for ICD Patients. The safety of sports participation for patients with implantable cardioverter defibrillators (ICDs) is unknown, and recommendations among physicians may vary widely. The purposes of this study were to determine current practice among patients with ICDs and their physicians regarding sports participation, and to determine how many physicians have cared for patients who have sustained adverse events during sports participation. A survey was mailed to all 1,687 U.S. physician members of the Heart Rhythm Society. Among 614 respondent physicians, recommendations varied widely. Only 10% recommended avoidance of all sports more vigorous than golf. Seventy-six percent recommended avoidance of contact, and 45% recommend avoidance of competitive sports. Most (71%) based restrictions on patients' underlying heart disease. Regardless of recommendations, most physicians (71%) reported caring for patients who participated in sports, including many citing vigorous, competitive sports, most commonly cited were basketball, running, and skiing. ICD shocks during sports were common, cited by 40% of physicians. However, few adverse consequences were reported. One percent of physicians reported known injury to patient (all but 3 minor); 5%, injury to the ICD system, and <1%, failure of shocks to terminate arrhythmia. The most common adverse event reported was lead damage attributed to repetitive-motion activities, most commonly weightlifting and golf. Physician recommendations for sports participation for patients with ICDs varies widely. Many patients with ICDs do participate in vigorous and even competitive sports. While shocks were common, significant adverse events were rare.

The blood donation experience: self-reported motives and obstacles for donating blood.

The aim of the study was to investigate motives for donating blood as well as difficulties and obstacles associated with blood donation as perceived by the donors themselves. Six hundred consecutive blood donors (i.e. all blood donors with a history of at least one previous whole blood donation attending, during nine working days, the Blood Centre of Umeå University Hospital) received a self-administered questionnaire that contained questions aimed at elucidating motives for donating blood (general motives for donating blood, specific motives for the first donation and motives for continuing to be an active blood donor). Questions concerning difficulties and obstacles that had to be overcome in order to continue being a blood donor were also included in the questionnaire. Altogether 531 whole blood donors filled in the questionnaire (88.5%; 322 men and 209 women). No statistically significant differences were found between male and female blood donors concerning general reasons and motives related to donating blood. The most frequently reported reasons for giving blood the first time were 'influence from a friend' (47.2% of donors) and 'request via media' (23.5% of donors). Among general reasons/motives with highest ranking of importance, the most commonly reported motive for donating blood were 'general altruism' (40.3%), 'social responsibility/obligation' (19.7%) and 'influence from friends' (17.9%). General altruism' and 'social responsibility/obligation' were also the most frequent reasons for continuing to donate blood (68.4 and 16.0%, respectively). The most commonly reported obstacle to becoming a regular blood donor was 'laziness' (19.1%) followed by 'fear of needles' (10.5%). Altruism was the most common general motive for donating blood and also for continuing to be an active blood donor. Yet, for the first blood donation, direct 'influence from friends/relatives', 'media appeal' and other types of recruitment were more commonly reported as reasons or motives for donating blood than altruism. The findings support the notion that different strategies should be used/adopted to get people to donate blood the first time (e.g. recruitment through other blood donors using, for example, the 'bring a friend along' method) and to retain these subjects as active blood donors (e.g. by information and by strengthening their sense of being a blood donor or their self-efficacy etc.).

Regular physical activity reduces the risk of hypertension, type 2 diabetes, coronary heart disease, stroke, and some cancers. Physical activity is associated inversely with overweight and obesity prevalence, thus potentially assisting in weight control efforts. The purpose of this paper is to examine the variability of physical activity levels and their patterns by self-reported weight control status in a nationally representative sample. Four years of data from the 1999-2002 National Health and Nutrition Examination Survey (NHANES) were used to examine leisure-time physical activity patterns (regular, irregular, inactive) and the prevalence of weight control practices (trying to lose, trying to maintain, not trying to lose or maintain) among U.S. adults (N = 9496). The prevalence of regular physical activity was 32.6% among people trying to lose weight, 37.9% among people trying to maintain weight, and 21.8% among those not trying to lose or maintain weight. Those trying to lose weight were almost three times as likely to be regularly active (vs inactive), and those trying to maintain weight were over three times more likely to be regularly active (vs inactive) than those not trying to lose or maintain weight. The most commonly reported activities among those trying to lose weight were walking (38.3%), yard work (14.5%), biking (12.5%), and running (11.6%). Despite the importance of physical activity, fewer than half the people trying to lose or maintain weight were regularly active during leisure-time. People trying to lose or maintain weight had a higher likelihood of being regularly active than those not trying to lose or maintain weight. Walking was the most common type of physical activity among all weight control groups. Health promotion efforts should promote increased levels of physical activity among all adults.

Illegal practice of medicine by medical students is a worldwide problem. In Brazil, information about this issue is scarce. To describe the perception of illegal practice of medicine by medical students. A cross-sectional study in a stratified random sample of 130 medical students in the 6th to 12th semesters from a private faculty of medicine in Salvador, State of Bahia, Brazil, from September to October 2011. Students responded to a standardised questionnaire about the illegal practice of medicine by medical students. Knowing medical students who practised medical activities without supervision was reported by 86% of the respondents, and 93.8% had heard about someone who performed such practices. Medical specialties most often associated with illegal practice were general medicine (78.8%) and occupational health (55.9%). Illegal practice of medicine was more common in peripheral cities/towns (83.9%) than in the State capital, Salvador City (52.4%). Only 10.5% of illegal activities were reported to the authorities. Unsupervised medical practice was more often reported in the 8th-9th semester (56.8%) and 10th-11th semester (54.4%) of medical school. Illegal practice of medicine was commonly reported by the medical students questioned. The high frequency of reported illegal practice for financial reasons highlights the need for greater availability of paid internships for medical students.

Rhabdomyolysis in a Sickle Cell Trait Positive Active Duty Male Soldier.

PubMed

Saxena, Pulkit; Chavarria, Christopher; Thurlow, John

2016-01-01

Exertional rhabdomyolysis is a complication of sickle cell trait (SCT) likely first reported in the military population over 40 years ago. Although commonly a benign condition, numerous studies and case reports have identified SCT positive patients to be at increased risk for rhabdomyolysis, compartment syndrome and sudden cardiac death. We report a recent case of an SCT positive African American active duty male Soldier who suffered exertional rhabdomyolysis following an Army Physical Fitness Test. His course was complicated by acute renal failure requiring hemodialysis, and he eventually recovered renal function. The diagnosis was significantly delayed despite a typical clinical presentation and available SCT screening results. The case highlights the importance of the recognition of SCT as a risk factor for severe rhabdomyolysis, and suggests more must be done for an effective SCT screening program for the active duty military population.

The perceived impacts of monitoring activities on intergovernmental relationships: some lessons from the Ecological Monitoring Network and Water in Focus.

PubMed

de Kool, Dennis

2015-11-01

An increasing stream of monitoring activities is entering the public sector. This article analyzes the perceived impacts of monitoring activities on intergovernmental relationships. Our theoretical framework is based on three approaches to monitoring and intergovernmental relationships, namely, a rational, a political, and a cultural perspective. Our empirical insights are based on two Dutch case studies, namely, the Ecological Monitoring Network and the Water in Focus reports. The conclusion is that monitoring activities have an impact on intergovernmental relationships in terms of standardizing working processes and methods, formalizing information relationships, ritualizing activities, and developing shared concepts ("common grammar"). An important challenge is to deal with the politicization of intergovernmental relationships, because monitoring reports can also stimulate political discussions about funding, the design of the instrument, administrative burdens, and supervisory relationships.

Oral sex: behaviours and feelings of Canadian young women and implications for sex education.

PubMed

Malacad, Brea L; Hess, Gretchen C

2010-06-01

Anecdotal reports indicate that, over the past decade, oral sex has become an increasingly common and casual activity among adolescent females. To investigate the validity of this claim the authors set out to study the oral sex practices of young women in Canada and to explore the attitudes and emotions that young women associate with oral sex. An anonymous self-report questionnaire, which contained questions pertaining to both vaginal intercourse and oral sex, was completed by 181 women aged 18-25 years. Approximately three quarters of the women in this sample had engaged in oral sex, a prevalence rate that was almost identical to that for vaginal intercourse. The mean age at first experience was approximately 17 years for both coitus and oral sex, though 27% of the sexually active participants had their first oral sex experience before age 16 (compared to 16% for coitus). Most women had their most recent sexual experiences within committed relationships and reported positive emotions associated with those experiences. Negative emotions at most recent oral sex were more commonly reported by the younger women in the sample and by those who were not in love with their partner. These results indicate that oral sex is at least as common as vaginal intercourse and that it has the same emotional implications for young women. Therefore, this topic should be given the same consideration as coitus within the context of sex education. Young people must be informed about risks, protective factors, and emotional implications associated with engagement in oral sex.

It is estimated that 70% of individuals with factor VIII deficiency hemophilia who received blood products before 1985 are infected with human immunodeficiency virus (HIV). The goal of the current study was to assess how adolescents with hemophilia cope with reminders of their HIV status, because adaptation is likely to have implications for these individuals' quality of life and adherence to safer sex recommendations. Participants included 297 HIV-positive adolescents with hemophilia who were recruited from 11 sites across the United States. Adolescents reported on the use and effectiveness of strategies for coping with reminders of their HIV status. A significant degree of distress was reported in response to such reminders, with anger being the most commonly reported emotion. Although a wide variety of coping strategies had been tried, participants reported using resignation (80.9%), self-calming (78.8%), and distraction (76.4%) most frequently in their attempts to cope with reminders of HIV. Self-blame (3.6%), engaging in risky behaviors (22.2%), thinking about sex (25.4%), and drug/alcohol use (29.1%) were used least. These adolescents tended to rate more active cognitive and behavioral coping strategies (eg, cognitive restructuring, seeking social support, physical activity) as most effective, whereas passive strategies (eg, wishful thinking, blaming others) were reported to be least helpful. Those individuals who reported being distressed by reminders of HIV endorsed most of the coping strategies significantly more often than the nondistressed group, although ineffective strategies were commonly chosen. Sexually active adolescents were more likely than their abstinent peers to cope by thinking about sex, engaging in risky behaviors, or using alcohol and drugs. In this population of adolescents who have known their serostatus for several years, distress about everyday reminders of HIV appears to be associated with ineffective coping strategies.

Meniscal injury produces disability in a large portion of the population, and sports injuries are a common cause. Atraumatic meniscal tears may occur after repetitive low-energy loading. Rowing is a highly technical sport and very demanding on an athlete’s body. There are numerous reports on patellofemoral and iliotibial band friction syndrome in rowers but there is an extremely low incidence of meniscal tears reported in these athletes. This is a unique case report of a young adolescent athlete who suffered bilateral medical meniscal tears during sporting activity. Rowing is a low impact sport making this an unusual occurrence, especially in a young individual. This case report highlights the importance of considering all training activities when trying to isolate the mechanism of injury in an athlete. PMID:21686387

A common endpoint of general anesthetics is behavioral unresponsiveness, which is commonly associated with loss of consciousness. However, subjects can become disconnected from the environment while still having conscious experiences, as demonstrated by sleep states associated with dreaming. Among anesthetics, ketamine is remarkable in that it induces profound unresponsiveness, but subjects often report "ketamine dreams" upon emergence from anesthesia. Here, we aimed at assessing consciousness during anesthesia with propofol, xenon, and ketamine, independent of behavioral responsiveness. To do so, in 18 healthy volunteers, we measured the complexity of the cortical response to transcranial magnetic stimulation (TMS)--an approach that has proven helpful in assessing objectively the level of consciousness irrespective of sensory processing and motor responses. In addition, upon emergence from anesthesia, we collected reports about conscious experiences during unresponsiveness. Both frontal and parietal TMS elicited a low-amplitude electroencephalographic (EEG) slow wave corresponding to a local pattern of cortical activation with low complexity during propofol anesthesia, a high-amplitude EEG slow wave corresponding to a global, stereotypical pattern of cortical activation with low complexity during xenon anesthesia, and a wakefulness-like, complex spatiotemporal activation pattern during ketamine anesthesia. Crucially, participants reported no conscious experience after emergence from propofol and xenon anesthesia, whereas after ketamine they reported long, vivid dreams unrelated to the external environment. These results are relevant because they suggest that brain complexity may be sensitive to the presence of disconnected consciousness in subjects who are considered unconscious based on behavioral responses.

Background Physical activity declines as children approach puberty. Research has focussed on psychosocial, environmental, and demographic determinants. This paper explores how family and socioeconomic factors are related to children's physical activity. Methods Seventeen focus groups were conducted with 113, 10–11 year old children from 11 primary schools in Bristol, UK. Focus groups examined: 1) the way parents encourage their children to be physically active; 2) the extent to which physical activity is engaged in as a family; and 3) the types of non-family based physical activities Year 6 children commonly participate in. Results Participants from all socioeconomic (SES) groups reported that parents encouraged them to be physically active. However approaches differed. Children from middle/high SES schools were assisted through actions such as logistical and financial support, co-participation and modelling. Parents of children from low SES schools mainly restricted their input to verbal encouragement and demands. Participation in family-based activities was reported to be higher in children from middle/high SES schools than children from low SES schools. All SES groups reported time to be a limiting factor in family-based activity participation. Cost was reported as a significant barrier by children from low SES schools. Children from middle/high SES schools reported engaging in more sports clubs and organised activities than children from low SES schools, who reported participating in more unstructured activities or 'free play' with friends. Conclusion The family is important for encouraging children to be physically active, but families from different socioeconomic backgrounds support their children in different ways. This research suggests that the design of physical activity interventions, which might include working with families, requires tailoring to groups from different socio-economic backgrounds.

Although weight control is important in managing knee osteoarthritis (OA), it is difficult to achieve. Understanding beliefs regarding weight management in people with knee OA may improve weight control. To examine differences in bodyweight satisfaction, weight management strategies and weight-related health-beliefs in obese, overweight and normal weight people with knee OA. The beliefs and attitudes to weight in 102 people with symptomatic knee OA were ascertained. Participants were classified as being obese, overweight or of normal weight. Although obese and overweight participants were less satisfied with their bodyweight, they were more likely to want to lose weight and to report dieting compared with normal weight participants(P < 0.001 for all) and also more likely to report weight gain in the past 6 months (P < 0.001). While most participants rated food intake to be a main determinant of health, this belief was more common in normal weight participants (P = 0.04). When asked about their own weight gain, obese participants more frequently believed genetic and metabolic factors to be important than normal and overweight participants (P = 0.01). While 51 (53%) believed that increasing activity was more important than dietary change to avoid weight gain, this was more commonly believed by obese and overweight participants (P < 0.05). Despite desiring and attempting to lose weight, obese people with symptomatic knee OA more commonly reported weight gain. Overweight and obese participants attributed weight gain to non-modifiable factors but believed physical activity is more important than dietary change in weight management. Thus, education regarding the importance of diet as compared with non-modifiable factors and physical activity may improve weight management in obese people with knee OA. © 2016 Royal Australasian College of Physicians.

The literature fails to reflect general agreement over the nature of the services and procedures provided by bioethicists, and the training and core competencies this work requires. If bioethicists are to define their activities in a consistent way, it makes sense to look for common ground in shared communities of practice. We report results of a survey of the services and procedures among bioethicists affiliated with the University of Toronto Joint Centre for Bioethics (JCB). This is the largest group of bioethicists working in healthcare organizations in Canada. The results suggest there are many common services and procedures of JCB bioethicists. This survey can serve as a baseline for further exploration of the work of JCB bioethicists. Common practices exist with respect to the domains of practice, individual reporting relationships, service availability within business hours and the education and training of the bioethicist.

Researchers have observed slower cooling rates in thigh muscle with greater overlying adipose tissue, suggesting that cryotherapy duration should be based on the adipose thickness of the treatment site. Skinfold data do not exist for other common cryotherapy sites, and no one has reported how those skinfolds might vary because of physical activity level or sex. To determine the variability in skinfold thickness among common cryotherapy sites relative to sex and activity level (National Collegiate Athletic Association Division I athletes, recreationally active college athletes). Descriptive laboratory study. Field. Three hundred eighty-nine college students participated; 196 Division I athletes (157 men, 39 women) were recruited during preseason physicals, and 193 recreationally active college athletes (108 men, 85 women) were recruited from physical education classes. Three skinfold measurements to within 1 mm were taken at 8 sites (inferior angle of the scapula, middle deltoid, ulnar groove, midforearm, midthigh, medial collateral ligament, midcalf, and anterior talofibular ligament [ATF]) using Lange skinfold calipers. Skinfold thickness in millimeters. We noted interactions among sex, activity level, and skinfold site. Male athletes had smaller skinfold measurements than female athletes at all sites except the ATF, scapula, and ulnar groove (F₇,₂₇₀₂ = 69.85, P < .001). Skinfold measurements were greater for recreationally active athletes than their Division I counterparts at all sites except the ATF, deltoid, and ulnar groove (F₇,₂₇₀₂ = 30.79, P < .001). Thigh skinfold measurements of recreationally active female athletes were the largest, and their ATF skinfolds were the smallest. Skinfold thickness at common cryotherapy treatment sites varied based on level of physical activity and sex. Therefore, clinicians should measure skinfold thickness to determine an appropriate cryotherapy duration.

Resting-state fMRI data reflects default network activity rather than null data: A defense of commonly employed methods to correct for multiple comparisons.

PubMed

Slotnick, Scott D

2017-07-01

Analysis of functional magnetic resonance imaging (fMRI) data typically involves over one hundred thousand independent statistical tests; therefore, it is necessary to correct for multiple comparisons to control familywise error. In a recent paper, Eklund, Nichols, and Knutsson used resting-state fMRI data to evaluate commonly employed methods to correct for multiple comparisons and reported unacceptable rates of familywise error. Eklund et al.'s analysis was based on the assumption that resting-state fMRI data reflect null data; however, their 'null data' actually reflected default network activity that inflated familywise error. As such, Eklund et al.'s results provide no basis to question the validity of the thousands of published fMRI studies that have corrected for multiple comparisons or the commonly employed methods to correct for multiple comparisons.

Hip impingement: identifying and treating a common cause of hip pain.

PubMed

Kuhlman, Geoffrey S; Domb, Benjamin G

2009-12-15

Femoroacetabular impingement, also known as hip impingement, is the abutment of the acetabular rim and the proximal femur. Hip impingement is increasingly recognized as a common etiology of hip pain in athletes, adolescents, and adults. It injures the labrum and articular cartilage, and can lead to osteoarthritis of the hip if left untreated. Patients with hip impingement often report anterolateral hip pain. Common aggravating activities include prolonged sitting, leaning forward, getting in or out of a car, and pivoting in sports. The use of flexion, adduction, and internal rotation of the supine hip typically reproduces the pain. Radiography, magnetic resonance arthrography, and injection of local anesthetic into the hip joint confirm the diagnosis. Pain may improve with physical therapy. Treatment often requires arthroscopy, which typically allows patients to resume premorbid physical activities. An important goal of arthroscopy is preservation of the hip joint. Whether arthroscopic treatment prevents or delays osteoarthritis of the hip is unknown.

Patients with Philadelphia chromosome-negative Myeloproliferative Neoplasms (MPNs) report fatigue as the most common symptom and contributing significantly to reduction in their quality of life (QoL). Targeted non-pharmacological intervention to increase levels of physical activity is suggested as a fatigue-reducing and QoL-enhancing intervention in MPN patients. The interrelationship between physical activity, fatigue, and QoL has, to our knowledge, never been reported. We analyzed data from 1807 MPN patients. The primary analysis included a multiple regression model allowing fatigue to mediate the relationship between physical activity and QoL. We herein report the first and the largest study of patients with MPNs, in whom we have investigated the interrelationship between fatigue, physical activity, and QoL. Sedentary patients were more likely to report fatigue compared to highly active patients. There was a negative association between fatigue and QoL, and there was a positive association between physical activity and QoL. There was no interaction between fatigue and physical activity in the association with QoL. We found positive associations between level of physical activity and QoL, independently of fatigue being present. More research is needed before physical activity can be introduced as a targeted intervention to reduce fatigue and increase QoL in the management of patients. © 2018 John Wiley & Sons A/S.

[Sexual counseling is important in cardiovascular disease. Returning to sexual activity is a common concern].

2014-12-02

Decreased sexual activity among cardiac patients is frequently reported. Rates of erectile dysfunction among men with cardiovascular disease (CVD) are twice as high as those in the general population with similar rates of sexual dysfunction in females with CVD. Returning to sexual activity is a common concern, and patients frequently request information on how to resume sexual activity. Partners also have considerable concerns, often more so than patients; why sexual counseling is important for both cardiac patients and their partners. In general, healthcare professionals, in caring for patients recognize the importance of discussing sexual function and activity and also express their responsibility to do so, although many healthcare professionals do not know what specific advice to give. Therefore, the intent of a consensus statement made by the American and European heart associations is to summarize current evidence related to sexual counseling in cardiovascular disease, and to provide direction to physicians, nurses, and other healthcare professionals in the practice of sexual counseling.

Prolonged elevations of glucocorticoids have been linked to the effective disturbances experienced by patients with Cushing's syndrome. Major depression has been most commonly reported in patients with endogenous Cushing's syndrome. The purpose of this study was to determine whether these patients experience melancholic or 'atypical' subtype depression and to determine relations between current psychological functioning and factors such as duration and severity of Cushing's syndrome. We examined 33 adult patients with documented Cushing's syndrome and 17 hospitalized, matched controls, using standardized structured interviews and tests. During the active phase of Cushing's syndrome (prior to and/or on admission), 66.7% of all patients reported histories meeting criteria for a psychiatric diagnosis. Of those with a diagnosis during Cushing's syndrome, 50% reported major depression. Upon presentation to this institution, atypical depression was the most common diagnosis involving 51.5% (n =17) of all enrolled patients. Of the 17 with atypical depression, 8 reported a co-morbid psychiatric disorder. The duration of Cushing's syndrome was an important factor in predicting whether patients sought psychological intervention or met criteria for psychiatric diagnosis. Patients with active endogenous Cushing's syndrome exhibit significant psychopathology expressed primarily by atypical depression. Longer duration of Cushing's syndrome may place them at increased risk of such psychopathology.

EPR study on non- and gamma-irradiated herbal pills

NASA Astrophysics Data System (ADS)

Aleksieva, K.; Lagunov, O.; Dimov, K.; Yordanov, N. D.

2011-06-01

The results of EPR studies on herbal pills of marigold, hawthorn, yarrow, common balm, tutsan, nettle and thyme before and after gamma-irradiation are reported. Before irradiation all samples exhibit one weak singlet EPR line with a g-factor of 2.0048±0.0005. After irradiation herbal pills could be separated in two groups according to their EPR spectra. Radiation-induced free radicals in pills of marigold, yarrow, nettle, tutsan and thyme could be attributed mainly to saccharide excipients. Tablets of hawthorn and common balm show "cellulose-like" EPR spectrum, superimposed on partly resolved carbohydrate spectrum, due to the active part (herb) and inulin, which is present in the pills as an excipient. Fading study of the radiation-induced EPR signals confirms that sugar radicals are more stable than cellulose species. The reported results show that the presence of characteristic EPR spectra of herbal pills due to excipients or active part can be used as unambiguous proof of radiation processing within 35 or more days after irradiation.

To analyze the clinical course, outcome, contributing factors and factors minimizing the incidents of perioperative myocardial ischemia or infarction (PMI) from Thai AIMS study. The present study was a prospective multicenter study. Data was collected from 51 hospitals in Thailand during a six-month period. The participating anesthesia provider completed the standardized incident report form of the Thai AIMS as soon as they found the PMI incident. Each incident was reviewed by three peer reviewers for clinical courses, contributing factors, outcome and minimizing factors of PMI. From the Thai AIMS incident report, the authors found 25 suspected PMI cases which was 0.9% of the 2,669 incidents reported in the present study. Most of the PMI occurred in elective cases (84%) and orthopedic procedures (56%). The majority of PMI was reported from the patients undergoing general anesthesia (72%). Suspected PMI occurred mostly during operations (56%). New ST-T segment change was detected in 92% of these patients. The most common immediate outcome of PMI was major physiological change (88%). The most common management effect of PMI was unplanned ICU admission (64%); the others were prolonged ventilatory support (12%) and prolonged hospital stay (16%). Four patients (16%) died after the suspected PMI. Most of the events occurred spontaneously and were unpreventable (80%). Patient factors (100%), anesthesia factors (72%), surgical factors (32%) and system factors (8%) were all judged as a precipitating factor for PMI. Human factors were the most common contributing factors which included poor preoperative evaluation, inexperience and improper decision. The three most common factors minimizing the adverse incidents included prior experienced, high awareness and experienced assistance. The recommended corrective strategies were guideline practice, quality assurance activity, improvement of supervision and additional training. Perioperative myocardial ischemia/infarction was infrequent but may be lethal. Patient factors were the most common precipitating cause. The morbidity and mortality could be reduced by high quality preoperative evaluation and preparation, early detection and appropriate treatment. Guideline practice, quality assurance activity, improvement of supervision and additional training were suggested corrective strategies.

Triathlon: running injuries.

The running portion of the triathlon represents the final leg of the competition and, by some reports, the most important part in determining a triathlete's overall success. Although most triathletes spend most of their training time on cycling, running injuries are the most common injuries encountered. Common causes of running injuries include overuse, lack of rest, and activities that aggravate biomechanical predisposers of specific injuries. We discuss the running-associated injuries in the hip, knee, lower leg, ankle, and foot of the triathlete, and the causes, presentation, evaluation, and treatment of each.

There is emerging evidence for the benefits of physical activity (PA) post-diagnosis for colorectal cancer (CRC) survivors. However, population studies suggest activity levels in these patients are very low. Understanding perceived barriers and benefits to activity is a crucial step in designing effective interventions. Patients who were between 6 months and 5 years post-diagnosis with non-metastasised disease were identified from five London (UK) hospitals. Four hundred and ninety five completed a lifestyle survey that included open-ended questions on their perceived barriers (what things would stop you from doing more physical activity?) and benefits (what do you think you would gain from doing more physical activity?). Patients also recorded their activity levels using the Godin Leisure Time Exercise Questionnaire, along with sociodemographic and treatment variables. The most commonly reported barriers related to cancer and its treatments (e.g. fatigue). Age and mobility-related comorbidities (e.g. impaired mobility) were also frequently cited. Those who reported age and mobility as barriers, or reported any barrier, were significantly less active even after adjustment for multiple confounders. The most frequently reported benefits were physiological (e.g. improving health and fitness). Cancer-related benefits (such as prevention of recurrence) were rarely reported. Those perceiving physiological benefits or perceiving any benefits were more active in unadjusted models, but associations were not significant in adjusted models. We have identified important barriers and facilitators in CRC survivors that will aid in the design of theory-based PA interventions.

Physical activity (PA) and smoking have been reported to be associated with the duration and severity of common cold symptoms. However, few studies have addressed the associations between the frequency of leisure-time exercise, cigarette smoking status and the frequency of the common cold in a cold area. This study was designed to investigate these issues in northeastern China. This cross-sectional study included individuals who participated in a regular health examination conducted in Jilin Province, China. Information on episodes of the common cold, the frequency of leisure-time exercise and cigarette smoking status in the past year were collected by self-administered health questionnaires. Ordinal logistic regression models were used to analyse the associations between the frequency of leisure-time exercise, cigarette smoking status and the retrospective frequency of common cold. A total of 1413 employees participated in the study, with an average age of 38.92 ± 9.04 years and 44.4% of them were male. Of all participants, 80.8% reported having experienced the common cold in the past year. After adjustment, the risk of suffering from the common cold more than once (odds ratios (ORs), 1.59; 95% confidence interval (CI), 1.27-1.99) in passive smokers was 1.59 times as high as that in non-smokers. Nevertheless, the results of the adjusted analysis showed no statistically significant relation between current smoking and the frequency of the common cold. A high frequency of leisure-time exercise (≥3 days/week) was associated with a 26% reduced risk of having at least one episode of the common cold (OR, 0.74; 95% CI, 0.55-0.98) compared with a low frequency group (< 4 days/month). For current and passive smokers, the protective effect of a high frequency of leisure-time exercise appears not to be obvious (current smokers: OR, 0.68; 95% CI, 0.33-1.43; passive smokers: OR, 1.15; 95% CI, 0.69-1.93). Passive smoking was associated with a higher risk of having self-reported common cold at least once, while a high frequency of leisure-time exercise was related to a lower risk of reporting more than one episode of the disease in Chinese.

Despite the high prevalence and consequences associated with externalizing psychopathologies, little is known about their underlying neurobiological mechanisms. Studying multiple externalizing disorders, each characterized by compromised inhibition, could reveal both common and distinct mechanisms of impairment. The present study therefore compared individuals with intermittent explosive disorder (IED) (N=11), individuals with cocaine use disorder (CUD) (N=21), and healthy controls (N=17) on task performance and functional magnetic resonance imaging (fMRI) activity during an event-related color-word Stroop task; self-reported trait anger expression was also collected in all participants. Results revealed higher error-related activity in the two externalizing psychopathologies as compared with controls in two subregions of the dorsolateral prefrontal cortex (DLPFC) (a region known to be involved in exerting cognitive control during this task), suggesting a neural signature of inhibitory-related error processing common to these psychopathologies. Interestingly, in one DLPFC subregion, error-related activity was especially high in IED, possibly indicating a specific neural correlate of clinically high anger expression. Supporting this interpretation, error-related DLPFC activity in this same subregion positively correlated with trait anger expression across all participants. These collective results help to illuminate common and distinct neural signatures of impaired self-control, and could suggest novel therapeutic targets for increasing self-control in clinical aggression specifically and/or in various externalizing psychopathologies more generally.

An estimated 200 million patients worldwide have surgery each year. Anesthesia and surgery have been reported to facilitate emergence of Alzheimer's disease. The commonly used inhalation anesthetic isoflurane has previously been reported to induce apoptosis, and to increase levels and aggregation of Alzheimer's disease-associated amyloid beta-protein (Abeta) in cultured cells. However, the in vivo relevance has not been addressed. We therefore set out to determine effects of isoflurane on caspase activation and levels of beta-site amyloid precursor protein-cleaving enzyme (BACE) and Abeta in naive mice, using Western blot, immunohistochemistry, and reverse transcriptase polymerase chain reaction. Here we show for the first time that a clinically relevant isoflurane anesthesia (1.4% isoflurane for 2 hours) leads to caspase activation and modest increases in levels of BACE 6 hours after anesthesia in mouse brain. Isoflurane anesthesia induces caspase activation, and increases levels of BACE and Abeta up to 24 hours after anesthesia. Isoflurane may increase BACE levels by reducing BACE degradation. Moreover, the Abeta aggregation inhibitor, clioquinol, was able to attenuate isoflurane-induced caspase-3 activation in vivo. Given that transient insults to brain may lead to long-term brain damage, these findings suggest that isoflurane may promote Alzheimer's disease neuropathogenesis and, as such, have implications for use of isoflurane in humans, pending human study confirmation.

To determine the proportion of people with gout who self-report triggers of acute attacks; identify the commonly reported triggers, and examine the disease and demographic features associated with self-reporting any trigger(s) of acute attacks of gout. Individuals with gout were asked to fill a questionnaire enquiring about triggers that precipitated their acute gout attacks. Binary logistic regression was used to compute odds ratio (OR) and 95% confidence intervals (CI) to examine the association between having ≥1 self-reported trigger of acute gout and disease and demographic risk factors and to adjust for covariates. All statistical analyses were performed using STATA. 550 participants returned completed questionnaires. 206 (37.5%) reported at least one trigger of acute attacks, and less than 5% reported >2 triggers. Only 28.73% participants reported that their most recent gout attack was triggered by dietary or lifestyle risk factors. The most frequently self-reported triggers were alcohol intake (14.18%), red-meat or sea-food consumption (6%), dehydration (4.91%), injury or excess activity (4.91%), and excessively warm or cold weather (4.36% and 5.45%). Patients who had onset of gout before the age of 50 years were significantly more likely to identify a trigger for precipitating their acute gout attacks (aOR (95%CI) 1.73 (1.12-2.68) after adjusting for covariates. Most people with gout do not identify any triggers for acute attacks, and identifiable triggers are more common in those with young onset gout. Less than 20% people self-reported acute gout attacks from conventionally accepted triggers of gout e.g. alcohol, red-meat intake, while c.5% reported novel triggers such as dehydration, injury or physical activity, and weather extremes.

Background Sydenham's chorea (SC) is the most common type of acquired chorea in childhood. In some cases, symptoms (most commonly described in terms of neurological signs) last up to 2 years, and many cases relapse. This report describes the clinical course in terms of functional abilities following diagnosis of SC. Case report Standardized assessments across the domains of activity and participation were administered following diagnosis, prior to and following treatment with haloperidol to measure treatment response and identify occupational therapy intervention needs. SC was observed to significantly reduce the child's participation and independence in activities of daily living. In this case, the standardized assessments administered highlighted difficulties with both motor and process skills. At 1 week after commencing haloperidol, both motor and process skills had improved. Clinically significant changes in self-care and mobility were noted with less improvement with handwriting. At 9 weeks, most symptoms and functional difficulties had resolved. Discussion Given the process difficulties detected in this case, and the possibility of enduring symptoms, the use of functional assessments is advocated in the routine management of SC. These findings illustrate the potential for motor and non-motor sequelae in acute childhood movement disorders and related functional disabling consequences. PMID:23532819

To evaluate progress toward prevention of enteric and foodborne illnesses in the United States, the Foodborne Diseases Active Surveillance Network (FoodNet) monitors the incidence of laboratory-confirmed infections caused by nine pathogens transmitted commonly through food in 10 U.S. sites. This report summarizes preliminary 2015 data and describes trends since 2012. In 2015, FoodNet reported 20,107 confirmed cases (defined as culture-confirmed bacterial infections and laboratory-confirmed parasitic infections), 4,531 hospitalizations, and 77 deaths. FoodNet also received reports of 3,112 positive culture-independent diagnostic tests (CIDTs) without culture-confirmation, a number that has markedly increased since 2012. Diagnostic testing practices for enteric pathogens are rapidly moving away from culture-based methods. The continued shift from culture-based methods to CIDTs that do not produce the isolates needed to distinguish between strains and subtypes affects the interpretation of public health surveillance data and ability to monitor progress toward prevention efforts. Expanded case definitions and strategies for obtaining bacterial isolates are crucial during this transition period.

For improvement of public awareness of the impact of space activities in China, a Space Situational Assessment Report 2013 will be issued in March 2014. More than ten Chinese main medium are invited for a special press conference. The Space Situational Assessment Report aims to introduce international space activities to Chinese public, and provide a common, comprehensive knowledge base to support the development of national policies and international security cooperation of outer space. The full report organizes international space activities until 2013 according to three parts those are Foundations, Strategies and Environment, including nine chapters, such as Space laws and policies; Space facility and equipment; Institutions and Human Resource; Military space, Civil space and Commercial space; Natural space environment; Space situational awareness, etc. A kind of Space Situational Assessment Index System is presented as a globally-focused analytic framework that defines, measures, and ranks national space activity. To use for a variety of public themes, different assessment indexes are constituted by scores of individual qualitative and quantitative metrics based on the Index System. Three research organizaitons of space sciences and technologies collaborated on the Space Situational Assessment Report. It is a scholarly and ungovernmental work.

2015-01-01

The aim was to investigate non-minor injuries sustained during outdoor activities among 0-12 year old children and to explore self-reported circumstances surrounding these incidents. During 2007-2009, the Umeå University Hospital injury database (IDB) registered 795 children with moderate (n = 778) and serious (n = 17) injuries, such as fractures. The IDB includes data from a questionnaire completed in the emergency department by the injured child or a parent. The open-ended questions catch the injured child's description of what circumstances precede the injury incident. The most commonly reported activities contributing to injuries were play, sport, and transport. Surface impacts were also reported as contributing factors along with products such as trampolines, bicycles, and downhill skis. By achieving a deeper knowledge about the activities and circumstances that precede non-minor injury incidents, creating safer outdoor environments may be feasible.

Preventing the common cold with a vitamin C supplement: a double-blind, placebo-controlled survey.

Van Straten, Michael; Josling, Peter

2002-01-01

One hundred sixty-eight volunteers were randomized to receive a placebo or a vitamin C supplement, two tablets daily, over a 60-day period between November and February. They used a five-point scale to assess their health and recorded any common cold infections and symptoms in a daily diary. Compared with the placebo group, the active-treatment group had significantly fewer colds (37 vs 50, P<.05), fewer days challenged virally (85 vs 178), and a significantly shorter duration of severe symptoms (1.8 vs 3.1 days, P<.03). Consequently, volunteers in the active group were less likely to get a cold and recovered faster if infected. Few side effects occurred with the active treatment, and volunteers reported greatly increased satisfaction with the study supplement compared with any previous form of vitamin C. This well-tolerated vitamin C supplement may prevent the common cold and shorten the duration of symptoms. Volunteers were generally impressed by the protection afforded them during the winter months and the general acceptability of the study medication.

Pathogenic variations in genes encoding aminoacyl-tRNA synthetases (ARSs) are increasingly associated with human disease. Clinical features of autosomal recessive ARS deficiencies appear very diverse and without apparent logic. We searched for common clinical patterns to improve disease recognition, insight into pathophysiology, and clinical care. Symptoms were analyzed in all patients with recessive ARS deficiencies reported in literature, supplemented with unreported patients evaluated in our hospital. In literature, we identified 107 patients with AARS, DARS, GARS, HARS, IARS, KARS, LARS, MARS, RARS, SARS, VARS, YARS, and QARS deficiencies. Common symptoms (defined as present in ≥4/13 ARS deficiencies) included abnormalities of the central nervous system and/or senses (13/13), failure to thrive, gastrointestinal symptoms, dysmaturity, liver disease, and facial dysmorphisms. Deep phenotyping of 5 additional patients with unreported compound heterozygous pathogenic variations in IARS, LARS, KARS, and QARS extended the common phenotype with lung disease, hypoalbuminemia, anemia, and renal tubulopathy. We propose a common clinical phenotype for recessive ARS deficiencies, resulting from insufficient aminoacylation activity to meet translational demand in specific organs or periods of life. Assuming residual ARS activity, adequate protein/amino acid supply seems essential instead of the traditional replacement of protein by glucose in patients with metabolic diseases.

Public health recommendations for older adults highlight the need to engage in a combination of aerobic, muscle strength, flexibility and balance activities. This study characterised leisure time physical activity in older Australians (≥ 65 years), examining the diversity in reported activities Cross-sectional monitoring. The Exercise Recreation and Sport Surveys (2001-2009) were combined and analysed for 22,050 elderly. Walking was reported by 45.6%, of those 53% engaged exclusively in walking. Prevalent sports (i.e., >1%) were bowls (9.4%), aerobics/callisthenics exercise (9.1%), golf (7.7%), swimming (6.4%), gym work (5.2%), cycling (3.2%), tennis (2.9%), dancing (2.1%), fishing (2.0%), tai chi (1.4%), weight lifting (1.2%) and yoga (1.1%). Significant gender differences were apparent. Over time, significant increases were reported in walking, aerobic/callisthenics and gym workout in both genders. In the previous year, 32.0% of older adults participated in "nil" activity, 40.6% engaged in one activity, 19.5% and 8.0% participated in two or three or more activities, respectively. Common combinations were walking with another aerobic activity. Only 2.6% reported a combination of aerobic, balance and strength activities. Multiple-activity participation increased over the years, but declined with increasing age, education and for the most disadvantaged, compared to single-activity participation. Partially or exclusively organised participation, combined, was reported by 42.5% of older adults. Women were more likely to combine mode of participation. Geographic region was associated with multiple-activity participation and organised-only participation. Most elderly people engage in one activity, if at all. An increase in participation in balance enhancing activities and weight training is warranted to maximize health benefits. Copyright © 2011 Sports Medicine Australia. Published by Elsevier Ltd.

2014-05-14

Achilles tendon ruptures tend to occur more commonly in healthy men between the ages of 30 and 50 years who have had no previous injury or problem reported in the affected leg. The injury is usually due to sudden forced plantar flexion of the foot, unexpected dorsiflexion of the foot and violent dorsiflexion of a plantar flexed foot, all of which occur during high impact activities. We present the first reported case of interactive activity with Nintendo Wii games that have resulted in Achilles tendon rupture in a 46-year-old man. There have been no previous reports of Achilles tendon rupture with Nintendo Wii usage; it is a relatively uncommon mode of injury and is rare in terms of epidemiology of motion sensing video game injuries. 2014 BMJ Publishing Group Ltd.

Objective To test the extent to which participants exposed to an uncommon versus common exercise stimulus would result in more favourable affect at post task. Design Experimental design. Participants, (N = 120) American women aged 18–45 years, were randomly assigned to complete 30-minutes of either the uncommon (HOOP; n = 58) or common (WALK; n = 62) exercise stimulus. Main Outcome Measures Self-reported affect and intentions for future exercise were measured before and after the 30-minute exercise bout. Results Analyses of covariance (ANCOVA) were run to compare post-task affect across the HOOP and WALK conditions. At post-task, participants assigned to HOOP reported more positively valenced affect, higher ratings of positive activated affect, lower ratings of negative deactivated affect, and stronger intentions for future aerobic exercise compared to participants assigned to WALK. Conclusions Participants who completed an uncommon bout of aerobic exercise (HOOP) reported more favourable affect post-exercise, as well as stronger intentions for future exercise, compared to participants who completed a common bout of aerobic exercise (WALK). Future work using a longitudinal design is needed to understand the relationships between familiarity with an exercise stimulus, affective responses to exercise, motivation for future exercise behaviour, and exercise maintenance over time.

Background Reference intervals are a vital part of reporting numerical pathology results. It is known, however, that variation in reference intervals between laboratories is common, even when analytical methods support common reference intervals. In response to this, in Australia, the Australasian Association of Clinical Biochemists together with the Royal College of Pathologists of Australasia published in 2014 a set of recommended common reference intervals for 11 common serum analytes (sodium, potassium, chloride, bicarbonate, creatinine male, creatinine female, calcium, calcium adjusted for albumin, phosphate, magnesium, lactate dehydrogenase, alkaline phosphatase and total protein). Methods Uptake of recommended common reference intervals in Australian laboratories was assessed using data from four annual cycles of the RCPAQAP reference intervals external quality assurance programme. Results Over three years, from 2013 to 2016, the use of the recommended upper and lower reference limits has increased from 40% to 83%. Nearly half of the intervals in use by enrolled laboratories in 2016 have been changed in this time period, indicating an active response to the guidelines. Conclusions These data support the activities of the Australasian Association of Clinical Biochemists and Royal College of Pathologists of Australasia in demonstrating a change in laboratory behaviour to reduce unnecessary variation in reference intervals and thus provide a consistent message to doctor and patients irrespective of the laboratory used.

Characterizing high-velocity angular vestibulo-ocular reflex function in service members post-blast exposure

Scherer, Matthew R.; Shelhamer, Mark J.; Schubert, Michael C.

2011-01-01

Blasts (explosions) are the most common mechanism of injury in modern warfare. Traumatic brain injury (TBI) and dizziness are common sequelae associated with blasts, and many service members (SMs) report symptoms worsen with activity. The purpose of this study was to measure angular vestibulo-ocular reflex gain (aVOR) of blast-exposed SMs with TBI during head impulse testing. We also assessed their symptoms during exertion. Twenty-four SMs recovering from TBI were prospectively assigned to one of two groups based on the presence or absence of dizziness. Wireless monocular scleral search coil and rate sensor were used to characterize active and passive yaw and pitch head and eye rotations. Visual analog scale (VAS) was used to monitor symptoms during fast walking/running. For active yaw head impulses, aVOR gains were significantly lower in the symptomatic group (0.79 ± 0.15) versus asymptomatic (0.87 ± 0.18), but not for passive head rotation. For pitch head rotation, the symptomatic group had both active (0.915 ± 0.24) and passive (0.878 ± 0.22) aVOR gains lower than the asymptomatic group (active 1.03 ± 0.27, passive 0.97 ± 0.23). Some SMs had elevated aVOR gain. VAS scores for all symptoms were highest during exertion. Our data suggest symptomatic SMs with TBI as a result of blast have varied aVOR gain during high-velocity head impulses and provide compelling evidence of pathology affecting the vestibular system. Potential loci of injury in this population include the following: disruption of pathways relaying vestibular efference signals, differential destruction of type I vestibular hair cells, or selective damage to irregular afferent pathways—any of which may explain the common discrepancy between reports of vestibular-like symptoms and laboratory testing results. significantly reduced pitch aVOR in symptomatic SMs and peak symptom severity during exertional testing support earlier findings in the chronic blast-exposed active duty SMs. PMID:21113582

This study examined the general characteristics of chief executive officers (CEOs) and their hospitals and the perceived impact of CEO turnover on various organizational activities. A mail-based survey included 156 hospital CEOs in 6 states in the West South Central, West North Central, and Mountain regions. Neither hospital and CEO characteristics nor the impact on various organizational activities and performance indicators was significantly different among the 6 states compared. Overall, CEOs reported relatively short tenures, frequent promotion from within the organization to CEO level, and common involuntary departure of their predecessors. Respondents overwhelmingly reported a positive impact of leadership change on financial performance, employee morale, and organizational culture.

Preliminary results of a 6 cm continuum survey using the NRAO VLA of binary systems with 10-100 day orbital period containing an 'active' giant component are reported. The results show that strong radio continuum emission at centimeter wavelengths is a common but not universal property of this class of stars. Possible correlations between radio luminosity and other properties, such as X-ray luminosity, rotational period, and type of companion are discussed. Several binary systems which have been detected for the first time as radio sources are reported, and sensitive upper limits are presented for five other systems, including Capella.

To summarize the effectiveness of interventions targeting psychosocial factors to increase physical activity (PA) among ethnic minority adults and explore theory use in PA interventions. Studies (N = 11) were identified through a systematic review and targeted African American/Hispanic adults, specific psychosocial factors, and PA. Data were extracted using a standard code sheet and the Theory Coding Scheme. Social support was the most common psychosocial factor reported, followed by motivational readiness, and self-efficacy, as being associated with increased PA. Only 7 studies explicitly reported using a theoretical framework. Future efforts should explore theory use in PA interventions and how integration of theoretical constructs, including psychosocial factors, increases PA.

The Godin Leisure-Time Exercise Questionnaire has been a commonly applied measure of physical activity in research among persons with multiple sclerosis over the past decade. This paper provides a comprehensive description of its application and inclusion in research on physical activity in multiple sclerosis. This comprehensive, narrative review included papers that were published between 1985 and 2017, written in English, involved participants with multiple sclerosis as a primary population, measured physical activity, and cited one of the two original Godin papers. There is a broad scope of research that has included the Godin Leisure-Time Exercise Questionnaire in persons with multiple sclerosis. Overall, 8 papers evaluated its psychometric properties, 21 evaluated patterns of physical activity, 24 evaluated correlates or determinants of physical activity, 28 evaluated outcomes or consequences of physical activity, and 15 evaluated physical activity interventions. The Godin Leisure-Time Exercise Questionnaire is a valid self-report measure of physical activity in persons with multiple sclerosis, and further is an appropriate, simple, and effective tool for describing patterns of physical activity, examining correlates and outcomes of physical activity, and provides a sensitive outcome for measuring change in physical activity after an intervention. Implications for rehabilitation There is increasing interest in physical activity and its benefits in multiple sclerosis. The study of physical activity requires appropriate and standardized measures. The Godin Leisure-Time Exercise Questionnaire is a common self-report measure of physical activity for persons with multiple sclerosis. Godin Leisure-Time Exercise Questionnaire scores are reliable measures of physical activity in persons with multiple sclerosis. The Godin Leisure-Time Exercise Questionnaire further is an appropriate, simple, and effective tool for describing patterns of physical activity, examining correlates and outcomes of physical activity participation, and is an advantageous primary outcome for measuring change in physical activity in response to an intervention.

Wang, Jun; Zhang, Mengya; Li, Shulan; He, Bingshu

2018-07-01

Now, the occurrence of pharmaceuticals in natural environment has been frequently reported around the world. As a kind of biologically active compounds specially designed to be effective even at very low concentration levels, pharmaceuticals in the environment could have adverse impacts to the health of human beings or other non-targeted organisms due to long-term exposures. To minimize the pharmaceutical pollution from the perspective of drug administration, a new concept called as eco-pharmacovigilance (EPV) has been proposed as a kind of pharmacovigilance(PV) for the environment. However, as a new and comprehensive science, EPV has not sophisticated methods in practice and formalized implementation model up to now. Since EPV is a special kind of PV, it could be feasible to draw on the experience of PV as a possible and reasonable starting point for EPV. In this paper, we discussed the common methods and activities used in PV including spontaneous reporting, intensive monitoring, database studies, and their potential applicability to the environment. And we concluded that these common methods in PV could be adapted and applied to EPV. But there is still the need for organizational, technical and financial supports of the EPV system.

2014-01-01

This study aimed to describe the prevalence of "suspected" of common mental disorders (CMD) in nursing workers at a general hospital in the state of Bahia. It was carried out a cross-sectional epidemiological study with 309 nursing workers, who worked in welfare activities in a large hospital. The nurses mentioned overwork and low pay. The most frequent health complaints were related to body posture and mental health. The overall prevalence of "suspected" of CMD was 35.0%. Regarding the psychosocial aspects of work, it was reported high psychological demand and low control over their work activities. The results indicated that the working and health conditions observed are not suitable for the effective realization of nursing work in the hospital.

2015-11-01

The aim of this study was to examine the availability of diverse job accommodations (or flexible working arrangements) and to describe their use among people with systemic lupus erythematosus (lupus), as well as to examine factors associated with the use of job accommodations. A mail survey was sent to adult lupus patients receiving care from a lupus clinic based in Toronto, Canada. The survey assessed demographic information, self-reported disease activity, work history, workplace activity limitations, job strain, and the availability and use of job accommodations. Standard multivariable linear regression analysis was used to examine factors associated with the use of job accommodations. We received 362 responses of 604 mailed surveys (60% response rate). Participants who were employed within the last 5 years, but who were not currently working, were less likely than currently employed participants to report having had job accommodations available to them at their last place of employment. The use of job accommodations was reported by 70% of currently employed respondents and by 72% of those not currently employed. The most common job accommodation used was sick leave days. Factors positively associated with the use of job accommodations among those who were employed included higher levels of education, being diagnosed with fibromyalgia, at least 1 episode of short-term work disability, not belonging to a union, greater workplace activity limitations, and greater job strain. The use of job accommodations among people with lupus is common. Work context factors, such as workplace activity limitations and job strain, are the main factors associated with the use of job accommodations. © 2015, American College of Rheumatology.

2016-11-01

The Active Healthy Kids Global Alliance organized the concurrent preparation of Report Cards on the physical activity of children and youth in 38 countries from 6 continents (representing 60% of the world's population). Nine common indicators were used (Overall Physical Activity, Organized Sport Participation, Active Play, Active Transportation, Sedentary Behavior, Family and Peers, School, Community and the Built Environment, and Government Strategies and Investments), and all Report Cards were generated through a harmonized development process and a standardized grading framework (from A = excellent, to F = failing). The 38 Report Cards were presented at the International Congress on Physical Activity and Public Health in Bangkok, Thailand on November 16, 2016. The consolidated findings are summarized in the form of a Global Matrix demonstrating substantial variation in grades both within and across countries. Countries that lead in certain indicators often lag in others. Average grades for both Overall Physical Activity and Sedentary Behavior around the world are D (low/poor). In contrast, the average grade for indicators related to supports for physical activity was C. Lower-income countries generally had better grades on Overall Physical Activity, Active Transportation, and Sedentary Behaviors compared with higher-income countries, yet worse grades for supports from Family and Peers, Community and the Built Environment, and Government Strategies and Investments. Average grades for all indicators combined were highest (best) in Denmark, Slovenia, and the Netherlands. Many surveillance and research gaps were apparent, especially for the Active Play and Family and Peers indicators. International cooperation and cross-fertilization is encouraged to address existing challenges, understand underlying determinants, conceive innovative solutions, and mitigate the global childhood inactivity crisis. The paradox of higher physical activity and lower sedentary behavior in countries reporting poorer infrastructure, and lower physical activity and higher sedentary behavior in countries reporting better infrastructure, suggests that autonomy to play, travel, or chore requirements and/or fewer attractive sedentary pursuits, rather than infrastructure and structured activities, may facilitate higher levels of physical activity.

Himalayan paeony (Paeonia emodi Royle.) is an important species used to treat various diseases. This study aimed to compile the detailed traditional medicinal uses, phytochemistry, pharmacology and toxicological investigations on P. emodi. This study also highlights taxonomic validity, quality of experimental designs and shortcomings in previously reported information on Himalayan paeony. The data was extracted from unpublished theses (Pakistan, China, India and Nepal), and different published research articles confined to pharmacology, phytochemistry and antimicrobial activities using different databases through specific keywords. The relevant information regarding medicinal uses, taxonomic/common names, part used, collection and identification source, authentication, voucher specimen number, plant extracts and their characterization, isolation and identification of phytochemicals, methods of study in silico, in vivo or in vitro, model organism used, dose and duration, minimal active concentration, zone of inhibition (antimicrobial study), bioactive compound(s), mechanism of action on single or multiple targets, and toxicological information. P. emodi is reported for diverse medicinal uses with pharmacological properties like antioxidant, nephroprotective, lipoxygenase inhibitory, cognition and oxidative stress release, cytotoxic, anti-inflammatory, antiepileptic, anticonvulsant, haemaglutination, alpha-chymotrypsin inhibitory, hepatoprotective, hepatic chromes and pharmacokinetics of carbamazepine expression, β-glucuronidase inhibitory, spasmolytic and spasmogenic, and airway relaxant. Data confined to its taxonomic validity, shows 10% studies with correct taxonomic name while 90% studies with incorrect taxonomic, pharmacopeial and common names. The literature reviewed, shows lack of collection source (11 reports), without proper source of identification (15 reports), 33 studies without voucher specimen number, 26 reports lack information on authentic herbarium submission and most of the studies (90%) without validation of taxonomic names using recognized databases. In reported methods, 67% studies without characterization of extracts, 25% lack proper dose, 40% without duration and 31% reports lack information on proper controls. Similarly, only 18% studies reports active compound(s) responsible for pharmacological activities, 14% studies show minimal active concentration, only 2.5% studies report mechanism of action on target while none of the reports mentioned in silico approach. P. emodi is endemic to Himalayan region (Pakistan, China, India and Nepal) with diverse traditional therapeutic uses. Majority of reviewed studies showed confusion in its taxonomic validity, incomplete methodologies and ambiguous findings. Keeping in view the immense uses of P. emodi in various traditional medicinal systems, holistic pharmacological approaches in combination with reverse pharmacology, system biology, and "omics" technologies are recommended to improve the quality of research which leads to natural drug discovery development at global perspectives.

Limited information is available regarding sexual functioning among adults aged 70 years and older. To assess sexual functioning among older men and women, and ascertain patient-physician communication patterns about sexual functioning. Prospective participants were approached prior to scheduled appointments with their primary care physician. In-depth sexual histories were obtained along with data on their demographic, medical, psychological, and cognitive status. Sexual functioning was assessed using standardized questionnaires, and simple yes/no questions were administered to ascertain information regarding patient-physician communication practices about sex. Of the 74 eligible patients approached, 50 (68%) participated. The participants had a mean age +/- standard deviation (SD) of 81 +/- 6 years and most (56%) were women. Eighteen percent of the women and 41% of the men were sexually active. The most commonly reported sexual activity was intercourse for men and masturbation for women. Among the women, the most commonly cited reason for being sexually inactive was "no desire," whereas for most men, it was "erectile dysfunction." Sexual function scores for women were low across each category (lubrication, desire, orgasm, arousal, pain, and satisfaction.) For men, low sexual function scores were found in the domains of erectile function, orgasm, and overall satisfaction, but not desire. Only 4% of the women (vs. 36% of men) reported initiating a discussion about sexual function with their physician in the past year, whereas 7% of the women (vs. 32% of men) reported that their physician inquired about the topic in the preceding year. Finally, 32% of the women (vs. 86% of men) felt that physicians should initiate discussions about sexual function. In this study of older adults, a minority reported current sexual activity. Among sexually inactive women, most did not wish to resume activity, whereas desire for sexual activity remained high among men, despite substantial problems with erectile dysfunction.

Gerressu, Makeda; Mercer, Catherine H; Graham, Cynthia A; Wellings, Kaye; Johnson, Anne M

2008-04-01

A stratified probability sample survey of the British general population, aged 16 to 44 years, was conducted from 1999 to 2001 (N = 11,161) using face-to-face interviewing and computer-assisted self-interviewing. We used these data to estimate the population prevalence of masturbation, and to identify sociodemographic, sexual behavioral, and attitudinal factors associated with reporting this behavior. Seventy-three percent of men and 36.8% of women reported masturbating in the 4 weeks prior to interview (95% confidence interval 71.5%-74.4% and 35.4%-38.2%, respectively). A number of sociodemographic and behavioral factors were associated with reporting masturbation. Among both men and women, reporting masturbation increased with higher levels of education and social class and was more common among those reporting sexual function problems. For women, masturbation was more likely among those who reported more frequent vaginal sex in the last four weeks, a greater repertoire of sexual activity (such as reporting oral and anal sex), and more sexual partners in the last year. In contrast, the prevalence of masturbation was lower among men reporting more frequent vaginal sex. Both men and women reporting same-sex partner(s) were significantly more likely to report masturbation. Masturbation is a common sexual practice with significant variations in reporting between men and women.

Emergency and transport ventilators use in the prehospital field is not well described. This study examines trends of ventilator use by EMS agencies during 911 calls in the United States and identifies factors associated with this use. This retrospective study used four consecutive releases of the US National Emergency Medical Services Information System (NEMSIS) public research dataset (2011-2014) to describe scene EMS activations (911 calls) with and without reported ventilator use. Ventilator use was reported in 260,663 out of 28,221,321 EMS 911 scene activations (0.9%). Patients with ventilator use were older (mean age 67±18years), nearly half were males (49.2%), mostly in urban areas (80.2%) and cared for by advanced life support (ALS) EMS services (89.5%). CPAP mode of ventilation was most common (71.6%). "Breathing problem" was the most common dispatch complaint for EMS activations with ventilator use (63.9%). Common provider impression categories included "respiratory distress" (72.5%), "cardiac rhythm disturbance" (4.6%), "altered level of consciousness" (4.3%) and "cardiac arrest"(4.0%). Ventilator use was consistently higher at the Specialty Care Transport (SCT) and Air Medical Transport (AMT) service levels and increased over the study period for both suburban and rural EMS activations. Significant factors for ventilator use included demographic characteristics, EMS agency type, specific complaints, provider's primary impressions and condition codes. Providers at different EMS levels use ventilators during 911 scene calls in the US. Training of prehospital providers on ventilation technology is needed. The benefit and effectiveness of this intervention remain to be assessed. Copyright © 2017 Elsevier Inc. All rights reserved.

Oral diseases are very prevalent across the lifespan and impact overall health, yet are largely preventable. The Smiles for Life (SFL) curriculum was created to educate healthcare providers about oral disease and support integration of oral health and primary care. This study examines SFL's influence on clinical practice and education. Surveys were sent to registered users of SFL. Users who self-identified as direct care providers (DCPs), or educators, were included in the analysis. Survey response rate was 18 percent, with 87 percent identifying as DCPs and 13 percent as educators. Across professions, 85 percent of DCPs reported SFL influencing their practice to some degree, with variance among profession type and experience. DCPs most commonly reported that SFL led them to improve how they conduct oral health activities, with 60 percent performing the activity more skillfully following completion of SFL. Fluoride varnish application was the most common practice behavior initiated, and caries risk assessments was the oral health activity affected to the greatest degree. A majority of educators (94 percent) reported that SFL led them to incorporate or enhance oral health in their teaching. SFL helped educators emphasize the importance of oral health, improved their ability to teach content, raised motivation, and reduced barriers to teaching oral health. Data supports that SFL is positively influencing oral health practice across professions, especially in areas of caries risk assessment and fluoride varnish application. SFL improves the frequency and quality with which DCPs and educators participate in oral health activities, and facilitates oral health inclusion in primary care. © 2017 American Association of Public Health Dentistry.

2016-03-01

To obtain information on the types of Australian horses, how they are kept and their activities. An invitation to participate in an opt-in, internet-based survey was sent to 7000 people who had registered an email address to receive information from the Australian Horse Industry Council Inc. There were 3377 (48%) useable responses from owners of 26,548 horses. Most horses were kept on small properties (usually 2-8 ha) in paddocks in rural areas of Queensland, New South Wales and Victoria. Most horses were female or geldings and the most common of 54 different activities was breeding. Owners reported 19,291 horses were used in different activities and 6037 (23%) horses were not kept for any stated purpose or activity. Owners used an average of 1.95 horses in 2.9 different types of activities. The most common of the 43 breeds were Thoroughbred, Australian Stock Horse and Australian Quarter Horse. Only 1% of the total numbers of Thoroughbreds and Standardbreds in this survey were used in horse racing, indicating there is a demand for these breeds in non-racing activities. Microchip was the most favoured method of horse identification and 36% favoured compulsory registration of horses. Most respondents reported owning some other animal species. There is a wide variation in horse breeds used in different activities by Australian horse owners. There are regional differences in various management systems. There needs to be considerable improvement in the collection and recording of information to improve the validity and reliability of horse industry data. © 2016 Australian Veterinary Association.

Distributed task coding throughout the multiple demand network of the human frontal-insular cortex.

PubMed

Stiers, Peter; Mennes, Maarten; Sunaert, Stefan

2010-08-01

The large variety of tasks that humans can perform is governed by a small number of key frontal-insular regions that are commonly active during task performance. Little is known about how this network distinguishes different tasks. We report on fMRI data in twelve participants while they performed four cognitive tasks. Of 20 commonly active frontal-insular regions in each hemisphere, five showed a BOLD response increase with increased task demands, regardless of the task. Although active in all tasks, each task invoked a unique response pattern across the voxels in each area that proved reliable in split-half multi-voxel correlation analysis. Consequently, voxels differed in their preference for one or more of the tasks. Voxel-based functional connectivity analyses revealed that same preference voxels distributed across all areas of the network constituted functional sub-networks that characterized the task being executed.

Lambrecht, Jeanne L; Cuevas, Jacqueline L

2007-06-01

To estimate association between field dependence-independence measured by scores on the Group Embedded Figures Test and young women's participation in sports activity. Participants were 37 undergraduate college women between the ages of 18 and 25 years (M=21). Participants were categorized into two groups, one high in participation in sports activity and one low. A one-tailed independent samples t test yielded no significant difference. Correlations of .36 and .18 were significant but account for little common variance. An ad hoc analysis performed without participants who reported softball activity but who were highly involved in sport activities was significant.

2016-01-01

Ganoderma lucidum (lingzhi) has been used for the general promotion of health in Asia for many centuries. The common method of consumption is to boil lingzhi in water and then drink the liquid. In this study, we examined the potential anticancer activities of G. lucidum submerged in two commonly consumed forms of alcohol in East Asia: malt whiskey and rice wine. The anticancer effect of G. lucidum, using whiskey and rice wine-based extraction methods, has not been previously reported. The growth inhibition of G. lucidum whiskey and rice wine extracts on the prostate cancer cell lines, PC3 and DU145, was determined. Using Affymetrix gene expression assays, several biologically active pathways associated with the anticancer activities of G. lucidum extracts were identified. Using gene expression analysis (real-time polymerase chain reaction [RT-PCR]) and protein analysis (Western blotting), we confirmed the expression of key genes and their associated proteins that were initially identified with Affymetrix gene expression analysis.

Intractable hyperkalemia due to nicorandil induced potassium channel syndrome.

PubMed

Chowdhry, Vivek; Mohanty, B B

2015-01-01

Nicorandil is a commonly used antianginal agent, which has both nitrate-like and ATP-sensitive potassium (K ATP ) channel activator properties. Activation of potassium channels by nicorandil causes expulsion of potassium ions into the extracellular space leading to membrane hyperpolarization, closure of voltage-gated calcium channels and finally vasodilatation. However, on the other hand, being an activator of K ATP channel, it can expel K + ions out of the cells and can cause hyperkalemia. Here, we report a case of nicorandil induced hyperkalemia unresponsive to medical treatment in a patient with diabetic nephropathy.

Calibration of self-report tools for physical activity research: the Physical Activity Questionnaire (PAQ)

PubMed Central

2014-01-01

Background The utility of self-report measures of physical activity (PA) in youth can be greatly enhanced by calibrating self-report output against objectively measured PA data. This study demonstrates the potential of calibrating self-report output against objectively measured physical activity (PA) in youth by using a commonly used self-report tool called the Physical Activity Questionnaire (PAQ). Methods A total of 148 participants (grades 4 through 12) from 9 schools (during the 2009–2010 school year) wore an Actigraph accelerometer for 7 days and then completed the PAQ. Multiple linear regression modeling was used on 70% of the available sample to develop a calibration equation and this was cross validated on an independent sample of participants (30% of sample). Results A calibration model with age, gender, and PAQ scores explained 40% of the variance in values for the percentage of time in moderate-to-vigorous PA (%MVPA) measured from the accelerometers (%MVPA = 14.56 - (sex*0.98) - (0.84*age) + (1.01*PAQ)). When tested on an independent, hold-out sample, the model estimated %MVPA values that were highly correlated with the recorded accelerometer values (r = .63) and there was no significant difference between the estimated and recorded activity values (mean diff. = 25.3 ± 18.1 min; p = .17). Conclusions These results suggest that the calibrated PAQ may be a valid alternative tool to activity monitoring instruments for estimating %MVPA in groups of youth. PMID:24886625

The utility of self-report measures of physical activity (PA) in youth can be greatly enhanced by calibrating self-report output against objectively measured PA data.This study demonstrates the potential of calibrating self-report output against objectively measured physical activity (PA) in youth by using a commonly used self-report tool called the Physical Activity Questionnaire (PAQ). A total of 148 participants (grades 4 through 12) from 9 schools (during the 2009-2010 school year) wore an Actigraph accelerometer for 7 days and then completed the PAQ. Multiple linear regression modeling was used on 70% of the available sample to develop a calibration equation and this was cross validated on an independent sample of participants (30% of sample). A calibration model with age, gender, and PAQ scores explained 40% of the variance in values for the percentage of time in moderate-to-vigorous PA (%MVPA) measured from the accelerometers (%MVPA = 14.56 - (sex*0.98) - (0.84*age) + (1.01*PAQ)). When tested on an independent, hold-out sample, the model estimated %MVPA values that were highly correlated with the recorded accelerometer values (r = .63) and there was no significant difference between the estimated and recorded activity values (mean diff. = 25.3 ± 18.1 min; p = .17). These results suggest that the calibrated PAQ may be a valid alternative tool to activity monitoring instruments for estimating %MVPA in groups of youth.

The aim of this study was to determine the prevalence of self-reported chronic idiopathic pain among adolescents in relation to age and gender, and to explore how pain interferes with daily activities. The study was performed in Nord-Trøndelag County, Norway in 2006-2008. All adolescents were invited to participate; the response rate was 78%. Participants completed a comprehensive questionnaire, including questions about pain and interference with everyday life. Chronic idiopathic pain was defined as pain at least once a week during the last 3 months, not related to any known disease or injury. The final study population, with complete pain questionnaires, consisted of 7373 adolescents aged 13-18 years. Chronic pain was reported by 44.4% of the participants, and 25.5% reported pain in at least 2 locations. Chronic idiopathic musculoskeletal pain was most prevalent (33.4%), and the neck/shoulder was most commonly affected. Musculoskeletal pain in 3 or more locations was reported by 8.5%. Pain almost daily was reported by 10.2%. More girls than boys reported pain. In girls, the prevalence of pain increased with age. A high number of pain-associated disabilities were reported, and 58.5% described difficulties doing daily activities in leisure time. Subjective disabilities were higher in girls, and increased with the frequency of pain and the number of pain locations, as shown by high disability in adolescents with musculoskeletal pain in 3 or more locations. Chronic idiopathic pain, especially multisite pain, is common among adolescents, and those suffering from it report a major impact on several areas of daily living.

2017-12-01

The purpose of this study was to identify common barriers and facilitators to healthy nutrition and exercise behaviors in the workplace and examine their relationships to those actual daily health behaviors. We utilized a concurrent embedded mixed methods approach to collect data from 93 participants over the span of four days. Participants reported 2.80 nutrition and 3.28 exercise barriers on average over the 4 days, while reporting 2.93 nutrition and 1.98 exercise facilitators in the same timeframe. Results indicated that workload and temptations around the office prevented nutritious eating; exercise behaviors were frequently hindered by workload. The most commonly mentioned eating facilitator was proper planning, while having time to exercise facilitated physical activity. Furthermore, the number of barriers reported negatively related to their respective health behaviors (i.e., more nutrition barriers translated to poorer nutrition habits) and facilitators were positively related to them, both overall and more so on the specific day they were reported. The implications of these finding show the importance of barriers/facilitators in the workplace and aid in the creation of more targeted health promotion that could increase positive employee health behaviors by eliminating common barriers and enhancing facilitators.

To report the kidney transplant activity and survival data during the past 25 years from the Thai Transplant Registry. By using the registry database that was collected and updated yearly by 26 transplant centres across the country, we have reported the donor, recipient, and transplant characteristics during the past 25 years from 1987 to 2012. The primary outcome was graft loss that was defined as return to dialysis, graft removal, retransplant, or patient death. 465 kidney transplants were performed in 2012, an 8.1% and 23.0% increase in living and deceased donor transplants compared to the previous year, respectively. Between 1987 and 2012 with the data of 3808 recipients, patient survival and graft survival improved significantly. Traffic accident was the most common cause of death in brain-dead donors. Additionally, the most common cause of end-stage kidney disease was glomerulonephritis. Infection has been among the most common causes of death in kidney transplant recipients. We have reported the total number, the graft and the patient survival data of kidney transplant recipients in Thailand for the period from 1987 to 2012. Although the number of patients is much lower than that in the developed countries, the patients and the graft survival rates are comparable. © 2014 Asian Pacific Society of Nephrology.

Inadequate research capacity impedes the development of evidence-based health programming in sub-Saharan Africa. However, funding for research capacity building (RCB) is often insufficient and restricted, limiting institutions' ability to address current RCB needs. The Doris Duke Charitable Foundation's African Health Initiative (AHI) funded Population Health Implementation and Training (PHIT) partnership projects in five African countries (Ghana, Mozambique, Rwanda, Tanzania and Zambia) to implement health systems strengthening initiatives inclusive of RCB. Using Cooke's framework for RCB, RCB activity leaders from each country reported on RCB priorities, activities, program metrics, ongoing challenges and solutions. These were synthesized by the authorship team, identifying common challenges and lessons learned. For most countries, each of the RCB domains from Cooke's framework was a high priority. In about half of the countries, domain specific activities happened prior to PHIT. During PHIT, specific RCB activities varied across countries. However, all five countries used AHI funding to improve research administrative support and infrastructure, implement research trainings and support mentorship activities and research dissemination. While outcomes data were not systematically collected, countries reported holding 54 research trainings, forming 56 mentor-mentee relationships, training 201 individuals and awarding 22 PhD and Masters-level scholarships. Over the 5 years, 116 manuscripts were developed. Of the 59 manuscripts published in peer-reviewed journals, 29 had national first authors and 18 had national senior authors. Trainees participated in 99 conferences and projects held 37 forums with policy makers to facilitate research translation into policy. All five PHIT projects strongly reported an increase in RCB activities and commended the Doris Duke Charitable Foundation for prioritizing RCB, funding RCB at adequate levels and time frames and for allowing flexibility in funding so that each project could implement activities according to their trainees' needs. As a result, many common challenges for RCB, such as adequate resources and local and international institutional support, were not identified as major challenges for these projects. Overall recommendations are for funders to provide adequate and flexible funding for RCB activities and for institutions to offer a spectrum of RCB activities to enable continued growth, provide adequate mentorship for trainees and systematically monitor RCB activities.

Stonefish envenomation with acute carpal tunnel syndrome.

Ling, Samuel K K; Cheng, S C; Yen, C H

2009-12-01

Stonefish envenomation is a common marine sting. Although stonefish injuries are commonly sustained during maritime activities, this local delicacy can also be considered a regional occupational hazard for chefs. The availability and consumption of stonefish in local restaurants has increased the risk of acute carpal tunnel syndrome after a stonefish injury. This case report describes acute carpal tunnel syndrome following stonefish envenomation. An excellent recovery was achieved after surgical decompression of the carpal tunnel syndrome. Standard management of stonefish injuries should therefore take into account the possibility that this orthopaedic emergency may complicate the injury.

2014-01-01

Although motivational disturbances are common in schizophrenia, their neurophysiological and psychological basis is poorly understood. This electroencephalography (EEG) study examined the well-established motivational direction model of asymmetric frontal brain activity in schizophrenia. According to this model, relative left frontal activity in the resting EEG reflects enhanced approach motivation tendencies, whereas relative right frontal activity reflects enhanced withdrawal motivation tendencies. Twenty-five schizophrenia outpatients and 25 healthy controls completed resting EEG assessments of frontal asymmetry in the alpha frequency band (8-12 Hz), as well as a self-report measure of behavioral activation and inhibition system (BIS/BAS) sensitivity. Patients showed an atypical pattern of differences from controls. On the EEG measure patients failed to show the left lateralized activity that was present in controls, suggesting diminished approach motivation. On the self-report measure, patients reported higher BIS sensitivity than controls, which is typically interpreted as heightened withdrawal motivation. EEG asymmetry scores did not significantly correlate with BIS/BAS scores or with clinical symptom ratings among patients. The overall pattern suggests a motivational disturbance in schizophrenia characterized by elements of both diminished approach and elevated withdrawal tendencies.

Physical activity (PA) levels are a key performance indicator for policy documents in Ireland. The first Ireland Report Card on Physical Activity in Children and Youth aims to set a robust baseline for future surveillance of indicators related to PA in children and youth. Data collected between 2003-2010 on more than 35,000 7- to 18-year-old children and youth were used and graded using a standardized grading system for 10 indicators. Grades assigned for the indicators were as follows: overall physical activity levels, D-; sedentary behavior (TV viewing), C-; organized sport participation, C-: physical education, D-; active play, inconclusive (INC); active transportation, D; school, C-, community and the built environment, B; family, INC; and government, INC. PA recommendations exist in Ireland but this Report Card has shown that participation is still low. A number of promising policies, programs and services are in place but these require thorough evaluation and adequate resourcing. Agreement and implementation of a common framework for the systematic surveillance of indictors related to PA of children and youth is necessary to monitor change over time and ensure the impact of promising work is captured.

Association of total daily physical activity with disability in community-dwelling older persons: a prospective cohort study

PubMed Central

2012-01-01

Background Based on findings primarily using self-report measures, physical activity has been recommended to reduce disability in old age. Collecting objective measures of total daily physical activity in community-dwelling older adults is uncommon, but might enhance the understanding of the relationship of physical activity and disability. We examined whether greater total daily physical activity was associated with less report of disability in the elderly. Methods Data were from the Rush Memory and Aging Project, a longitudinal prospective cohort study of common, age-related, chronic conditions. Total daily physical activity was measured in community-dwelling participants with an average age of 82 using actigraphy for approximately 9 days. Disability was measured via self-reported basic activities of daily living (ADL). The odds ratio and 95% Confidence Interval (CI) were determined for the baseline association of total daily physical activity and ADL disability using a logistic regression model adjusted for age, education level, gender and self-report physical activity. In participants without initial report of ADL disability, the hazard ratio and 95% CI were determined for the relationship of baseline total daily physical activity and the development of ADL disability using a discrete time Cox proportional hazard model adjusted for demographics and self-report physical activity. Results In 870 participants, the mean total daily physical activity was 2. 9 × 105 counts/day (range in 105 counts/day = 0.16, 13. 6) and the mean hours/week of self-reported physical activity was 3.2 (SD = 3.6). At baseline, 718 (82.5%) participants reported being independent in all ADLs. At baseline, total daily physical activity was protective against disability (OR per 105 counts/day difference = 0.55; 95% CI = 0.47, 0.65). Of the participants without baseline disability, 584 were followed for 3.4 years on average. Each 105 counts/day additional total daily physical activity was associated with reduced hazard of developing disability by 25% (HR = 0.75, 95% CI = 0.66, 0.84). The results were unchanged after controlling for important covariates including cognition, depressive symptoms, and chronic health conditions. Conclusions Greater total daily physical activity is independently associated with less disability even after controlling for self-reported physical activity. PMID:23072476

The Multimedia Activity Recall for Children and Adolescents (MARCA): development and evaluation.

2006-05-26

Self-report recall questionnaires are commonly used to measure physical activity, energy expenditure and time use in children and adolescents. However, self-report questionnaires show low to moderate validity, mainly due to inaccuracies in recalling activity in terms of duration and intensity. Aside from recall errors, inaccuracies in estimating energy expenditure from self-report questionnaires are compounded by a lack of data on the energy cost of everyday activities in children and adolescents. This article describes the development of the Multimedia Activity Recall for Children and Adolescents (MARCA), a computer-delivered use-of-time instrument designed to address both the limitations of self-report recall questionnaires in children, and the lack of energy cost data in children. The test-retest reliability of the MARCA was assessed using a sample of 32 children (aged 11.8 +/- 0.7 y) who undertook the MARCA twice within 24-h. Criterion validity was assessed by comparing self-reports with accelerometer counts collected on a sample of 66 children (aged 11.6 +/- 0.8 y). Content and construct validity were assessed by establishing whether data collected using the MARCA on 1429 children (aged 11.9 +/- 0.8 y) exhibited relationships and trends in children's physical activity consistent with established findings from a number of previous research studies. Test-retest reliability was high with intra-class coefficients ranging from 0.88 to 0.94. The MARCA demonstrated criterion validity comparable to other self-report instruments with Spearman coefficients ranging from rho = 0.36 to 0.45, and provided evidence of good content and construct validity. The MARCA is a valid and reliable self-report questionnaire, capable of a wide variety of flexible use-of-time analyses related to both physical activity and sedentary behaviour, and offers advantages over existing pen-and-paper questionnaires.

Objectives Injuries account for a substantial proportion of the burden of disease in adolescents globally. This paper describes injury rates and associated exposures, and risk behaviors in Oman’s 2010 Global School-based Student Health Survey (GSHS). Methods This study used complex samples analysis to examine nationally-representative data from 1 606 students in grades eight, nine, and 10 who participated in the 2010 Oman GSHS. Results In total, 34.0% of the students reported having at least one injury in the past year that caused at least one full day abscence from usual activities or required medical treatment. The most common injury type reported was a broken bone or dislocated joint. The most common injury cause was falling. Additionally, 38.4% of the students reported being bullied in the past month, 38.8% reported being physically attacked in the past year, and 47.6% reported being in physical fights. Both injured boys and girls reported experiencing significantly more bullying, fights, and attacks (odds ratio > 2) than their non-injured classmates, even though only 9.6% of injured students reported that their most serious injury in the past year was the result of an assault, and students reporting assaults did not have significantly higher odds of exposure to these types of peer violence. More than half of the bullied students reported that the most frequent type of peer victimization they experienced was being made fun of with sexual jokes, comments, or gestures. Sexual bullying was the most common type of bullying reported by girls and boys. Conclusions Promoting healthier peer relationships may help to reduce injuries in this age group as well as reducing the harmful effects of bullying. PMID:28439379

Ban-Lan-Gen is the common name for the dried roots of indigo plants, including Polygonum tinctorium, Isatis indigotica, Isatis tinctoria, and Strobilanthes cusia. Ban-Lan-Gen is frequently used as an anti-inflammatory and an anti-viral for the treatment of hepatitis, influenza, and various types of inflammation. One of the cytochrome P450 (CYP) enzymes, CYP3A4, is responsible for the metabolism of a wide variety of xenobiotics, including an estimated 60% of all clinically used drugs. In this study, we investigated the effect of Ban-Lan-Gen on the transcriptional activation of the CYP3A4 gene. Ban-Lan-Gen extract increased CYP3A4 gene reporter activity in a dose-dependent manner. Indirubin, one of the biologically active ingredients in the Ban-Lan-Gen, also dose-dependently increased CYP3A4 gene reporter activity. Expression of short hairpin RNA for the human pregnane X receptor (hPXR-shRNA) inhibited CYP3A4 gene reporter activity, and overexpression of human PXR increased indirubin- and rifampicin-induced CYP3A4 gene reporter activity. Furthermore, indirubin induced CYP3A4 mRNA expression in HepG2 cells. Taken together, these results indicate that indirubin, a component of Ban-Lan-Gen, activated CYP3A4 gene transcription through the activation of the human PXR. Copyright © 2016.

Background With limited opportunities for physical activity during school hours, it is important to understand the contexts of physical activities done outside of school time. Given the importance of physical and social aspects of environments, the purpose of this study was to describe where and with whom girls participate in physical activities outside of school. Methods Participants were 1925 sixth-grade girls in the Trial of Activity for Adolescent Girls (TAAG). At baseline, they completed a 3-day physical activity recall (3DPAR), reporting the main activity performed during 30-minute intervals and the physical and social contexts of physical activities. Results The most frequently reported physical activities done outside of school time were house chores, walking (for transportation or exercise), dance, basketball, playing with younger children, and running or jogging. The most common location for these activities was at home or in the neighborhood. With the exception of household chores, these activities were typically done with at least one other person. Conclusions Interventions that promote physical activities that can be done at or around home or developing supportive social networks for physical activity would be consistent with the current physical activity contexts of adolescent girls.

Paediatric obesity, physical activity and the musculoskeletal system.

Shultz, S P; Anner, J; Hills, A P

2009-09-01

The current epidemic of paediatric obesity is consistent with a myriad of health-related comorbid conditions. Despite the higher prevalence of orthopaedic conditions in overweight children, a paucity of published research has considered the influence of these conditions on the ability to undertake physical activity. As physical activity participation is directly related to improvements in physical fitness, skeletal health and metabolic conditions, higher levels of physical activity are encouraged, and exercise is commonly prescribed in the treatment and management of childhood obesity. However, research has not correlated orthopaedic conditions, including the increased joint pain and discomfort that is commonly reported by overweight children, with decreases in physical activity. Research has confirmed that overweight children typically display a slower, more tentative walking pattern with increased forces to the hip, knee and ankle during 'normal' gait. This research, combined with anthropometric data indicating a higher prevalence of musculoskeletal malalignment in overweight children, suggests that such individuals are poorly equipped to undertake certain forms of physical activity. Concomitant increases in obesity and decreases in physical activity level strongly support the need to better understand the musculoskeletal factors associated with the performance of motor tasks by overweight and obese children.

Psychosocial impact of onychomycosis: a review.

Onychomycosis (tinea unguium) is the most common nail disorder. Nonetheless, it requires lengthy, often ineffective treatments, and recurrence is frequent. Predominantly a disease of the elderly, onychomycosis is becoming more and more common. Besides interfering with normal nail function, fungal nail infections are relatively painful, unsightly in appearance, disrupt daily activities, and have a negative psychosocial connotation. Commonly reported psychosocial factors are embarrassment, low self-esteem, and social withdrawal. Yet advances in therapy have been achieved since these reports were made, and many of these treatment options have proven to be more effective. Thus, the impact of these advances on psychosocial well-being of patients with onychomycosis is worth analyzing. The objective of this paper is to review studies that investigated the psychosocial impact of onychomycosis on a variety of patient populations. An alternative, total patient approach that dermatologists and general practitioners alike could use to incorporate patients' psychosocial well-being into the holistic management of onychomycosis will also be discussed. © 2013 The International Society of Dermatology.

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.

2015-07-01

Mixtures of organophosphate (OP) and carbamate (CB) pesticides are commonly detected in freshwater ecosystems. These pesticides inhibit the activity of acetylcholinesterase (AChE) and have potential to interfere with behaviors that may be essential for the survival of species. Although the effects of individual anticholinesterase insecticides on aquatic species have been studied for decades, the neurotoxicity of mixtures is still poorly understood. In the present study, brain AChE inhibition in carp (Cyprinus carpio) exposed to a series of concentrations of the organophosphates (malathion and triazophos) as well as the carbamates (fenobucarb and carbosulfan) was measured. In equitoxic mixtures, the observed AChE activity inhibition of the malathion plus triazophos, and triazophos plus carbosulfan mixtures, was synergism. In equivalent concentration mixtures, the combination of malathion plus fenobucarb mixture conformed to synergism, while the observed AChE activity inhibition of the remaining pairings was less than additive. Single pesticide risk assessments are likely to underestimate the impacts of these insecticides on carps in aquatic environment where mixtures occur. Moreover, mixtures of pesticides that have been commonly reported in aquatic ecosystems may pose a more important challenge than previously anticipated. Copyright © 2014 Elsevier Inc.

Evidence suggests physical activity often declines during pregnancy, however explanations for the decline are not well understood. The aim of this study was to identify modifiable barriers to leisure-time physical activity among women who did not meet physical activity guidelines during pregnancy. Analyses were based on data from 133 mothers (~3-months postpartum) who were recruited from the Melbourne InFANT Extend study (2012/2013). Women completed a self-report survey at baseline in which they reported their leisure-time physical activity levels during pregnancy as well provided an open-ended written response regarding the key barriers that they perceived prevented them from meeting the physical activity guidelines during their pregnancy. Thematic analyses were conducted to identify key themes. The qualitative data revealed six themes relating to the barriers of leisure-time physical activity during pregnancy. These included work-related factors (most commonly reported), tiredness, pregnancy-related symptoms, being active but not meeting the guidelines, lack of motivation, and a lack of knowledge of recommendations. Considering work-related barriers were suggested to be key factors to preventing women from meeting the physical activity guidelines during pregnancy, workplace interventions aimed at providing time management skills along with supporting physical activity programs for pregnant workers should be considered. Such interventions should also incorporate knowledge and education components, providing advice for undertaking leisure-time physical activity during pregnancy.

Background Bacterial vaginosis is a common vaginal infection, causing an abnormal vaginal discharge and/or odour in up to 50% of sufferers. Recurrence is common following recommended treatment. There are limited data on women’s experience of bacterial vaginosis, and the impact on their self-esteem, sexual relationships and quality of life. The aim of this study was to explore the experiences and impact of recurrent bacterial vaginosis on women. Methods A social constructionist approach was chosen as the framework for the study. Thirty five women with male and/or female partners participated in semi-structured interviews face-to-face or by telephone about their experience of recurrent bacterial vaginosis. Results Recurrent bacterial vaginosis impacted on women to varying degrees, with some women reporting it had little impact on their lives but most reporting it had a moderate to severe impact. The degree to which it impacted on women physically, emotionally, sexually and socially often depended on the frequency of episodes and severity of symptoms. Women commonly reported that symptoms of bacterial vaginosis made them feel embarrassed, ashamed, ‘dirty’ and very concerned others may detect their malodour and abnormal discharge. The biggest impact of recurrent bacterial vaginosis was on women’s self-esteem and sex lives, with women regularly avoiding sexual activity, in particular oral sex, as they were too embarrassed and self-conscious of their symptoms to engage in these activities. Women often felt confused about why they were experiencing recurrent bacterial vaginosis and frustrated at their lack of control over recurrence. Conclusion Women’s experience of recurrent bacterial vaginosis varied broadly and significantly in this study. Some women reported little impact on their lives but most reported a moderate to severe impact, mainly on their self-esteem and sex life. Further support and acknowledgement of these impacts are required when managing women with recurrent bacterial vaginosis. PMID:24040236

Bacterial vaginosis is a common vaginal infection, causing an abnormal vaginal discharge and/or odour in up to 50% of sufferers. Recurrence is common following recommended treatment. There are limited data on women's experience of bacterial vaginosis, and the impact on their self-esteem, sexual relationships and quality of life. The aim of this study was to explore the experiences and impact of recurrent bacterial vaginosis on women. A social constructionist approach was chosen as the framework for the study. Thirty five women with male and/or female partners participated in semi-structured interviews face-to-face or by telephone about their experience of recurrent bacterial vaginosis. Recurrent bacterial vaginosis impacted on women to varying degrees, with some women reporting it had little impact on their lives but most reporting it had a moderate to severe impact. The degree to which it impacted on women physically, emotionally, sexually and socially often depended on the frequency of episodes and severity of symptoms. Women commonly reported that symptoms of bacterial vaginosis made them feel embarrassed, ashamed, 'dirty' and very concerned others may detect their malodour and abnormal discharge. The biggest impact of recurrent bacterial vaginosis was on women's self-esteem and sex lives, with women regularly avoiding sexual activity, in particular oral sex, as they were too embarrassed and self-conscious of their symptoms to engage in these activities. Women often felt confused about why they were experiencing recurrent bacterial vaginosis and frustrated at their lack of control over recurrence. Women's experience of recurrent bacterial vaginosis varied broadly and significantly in this study. Some women reported little impact on their lives but most reported a moderate to severe impact, mainly on their self-esteem and sex life. Further support and acknowledgement of these impacts are required when managing women with recurrent bacterial vaginosis.

Non-specific musculoskeletal pain symptoms are common in adolescents and may differ between the sexes, and be related to age and daily activities. It is critical to examine the prevalence and frequency of symptoms in adolescent students who tend to have pain which interferes with their routine activities. This study aimed to explore the prevalence and frequency of self-reported musculoskeletal pain symptoms by age and sex, and we also examined the association of symptoms with routine activities of school-age adolescents by area of pain. A cross-sectional survey was conducted among Thai students aged 10-19 years. All 2,750 students were asked to report previous 7-day and/or 12-month pain using the Standardized Nordic Questionnaire (Thai version) in 10 body areas. Multivariable logistic regression adjusted for age and sex was used to analyze the association between daily activity and musculoskeletal pain symptoms. A total of 76.1% (n=2,093) of students reported experiencing pain in the previous 7 days, 73.0% (n=2,007) reported in the previous 12-month period and 83.8% (n=2,304) reported pain in both 7-day and 12-month periods. The most common pain area was from a headache, with other areas being neck and shoulders, in that order, for both periods of time. The prevalence of musculoskeletal pain was especially higher in older groups and females. Participants reported frequency of pain as "sometimes in different areas" ranging from 78.4% to 88% and severity of pain at 3.82±2.06 out of 10 (95% CI 3.74-3.91). Routine daily activities associated with symptoms of headache, neck, shoulders, and ankles or feet pain were computer use (head, OR=2.22), school bag carrying (neck, OR=2.05), school bag carrying (shoulder, OR=3.09), and playing sports (ankle or foot, OR=2.68). The prevalence of musculoskeletal pain symptoms was high in both the previous 7-day and 12-month periods, especially in females and older adolescents, although most of them sometimes experienced pain. Computer use and school bag carrying were associated with headache, neck and shoulder pain, while playing sports was related to symptoms of the foot and ankle. The prevalence of pain was high, particularly in the older and female groups. Although they experienced mild symptoms sometimes, the related daily activities leading to these symptoms should be closely noticed.

To examine whether fear of falling is a probable cause of reduced recreational physical activity levels in healthy older women. Cross-sectional analysis of baseline data from a longitudinal study. One thousand five hundred older, ambulatory women (aged 70-85), selected at random from the electoral roll. Self-reported recreational physical activity levels and fear of falling, demographic variables, anthropometric variables and measures of disability, and physical and cognitive function. The study subjects had low levels of physical and cognitive impairments; 24.1% of the group was obese (body mass index> 30). Twenty-six percent of the women did not participate in recreational physical activity; 39% participated in sufficient activity to gain probable health benefits. Although the women who did not participate in recreational activities were most likely to report fear of falling (45.2%), it was common in the group as a whole (33.9%), including the most active women (27.0%). Independent risk factors for nonparticipation in physical activity were fear of falling (odds ratio (OR)=0.70, 95% confidence interval (CI)=0.54-0.90, P=.006), obesity (OR=0.50, 95% CI=0.38-0.66, P=.001), and slower times on the timed up-and-go test (OR=0.88, 95% CI=0.84-0.92, P=.001). Fear of falling was also independently associated with lower recreational physical activity levels in women who were active (beta=-0.09, P=.003). Subgroup analysis suggested that fear of falls affected activity levels at a predisability stage in women with mildly impaired mobility. Fear of falling is common in healthy, high-functioning older women and is independently associated with reduced levels of participation in recreational physical activity. Fear of falling is an important psychological barrier that may need to be overcome in programs attempting to improve activity levels in older women.

Spinal cord injury influences psychogenic as well as physical components of female sexual ability.

Secure, web-based survey. Elicit specific information about sexual function from women with spinal cord injuries (SCI). World-wide web. Individuals 18 years or older living with SCI obtained a pass code to enter a secure website and then answered survey questions. Bladder and/or bowel incontinence during sexual activity and/or sexual intercourse were significant concerns and prevented some women from seeking sexual activity. Autonomic dysreflexia (AD) during sexual activity was interpreted negatively by many and was found to interfere with sexual activity. Most subjects reported difficulty becoming psychologically aroused as well as physically aroused, which were both correlated with feeling that their SCI had altered their sexual sense of self. An inverse relationship existed between developing new areas of arousal above the level of lesion and not having sensation or movement below the lesion. The most commonly reported sexual stimulation leading to the best arousal involved stimulation of the head/neck and torso areas. The majority of subjects reported having experienced intercourse postinjury. Most participants reported difficulty with positioning during foreplay and intercourse, vaginal lubrication, and spasticity during intercourse. Almost half reported experiencing orgasm postinjury and this was positively associated with the presence of genital sensation. SCI significantly impairs psychological and physical aspects of female sexual arousal. In addition, bladder and bowel incontinence as well as AD negatively impact sexual activity and intercourse.

No large case series of gastrointestinal histoplasmosis (GIH) in patients with AIDS has been published. We report 18 cases and review 34 published cases in the medical literature. We did a retrospective chart review from patients seen in our medical practices between 1989 and 2004. Most of our patients were men who had sex with men and who were not receiving highly active antiretroviral therapy. Median CD4 count was 34/muL. The most common presenting symptoms were diarrhea, fever, abdominal pain, and weight loss. The most commonly involved site was the colon or cecum. Biopsies revealed visible Histoplasma capsulatum organisms in 89%. Cultures from any site were positive in 76.9%. Four patients died from GIH. Gastrointestinal histoplasmosis occurs in severely immunocompromised patients with AIDS not receiving highly active antiretroviral therapy. Typical manifestations include diarrhea, fever, abdominal pain, and weight loss. Diagnosis is confirmed by blood or gastrointestinal tissue culture. Improvements in antiretroviral and antifungal therapies appear to have reduced the incidence of GIH and may improve the prognosis of this disease.

Effect of leisure time physical activity on severe knee or hip osteoarthritis leading to total joint replacement: a population-based prospective cohort study

PubMed Central

2012-01-01

Background Studies on leisure time physical activity as risk factor or protective factor for knee or hip osteoarthritis (OA) show divergent results. Longitudinal prospective studies are needed to clarify the association of physical activity with future OA. The aim was to explore in a prospective population-based cohort study the influence of leisure time physical activity on severe knee or hip OA, defined as knee or hip replacement due to OA. Methods Leisure time physical activity was reported by 28320 participants (mean age 58 years (SD 7.6), 60% women) at baseline. An overall leisure time physical activity score, taking both duration and intensity of physical activities into account, was created. The most commonly reported activities were also used for analysis. The incidence of knee or hip replacement due to OA over 11 years was monitored by linkage with the Swedish hospital discharge register. Cox’s proportional hazards model (crude and adjusted for potential confounding factors) was used to assess the incidence of total joint replacement, or osteotomy (knee), in separate analyses of leisure time physical activity. Results There was no significant overall association between leisure time physical activity and risk for knee or hip replacement due to OA over the 11-year observation time. For women only, the adjusted RR (95% CI) for hip replacement was 0.66 (0.48, 0.89) (fourth vs. first quartile), indicating a lower risk of hip replacement in those with the highest compared with the lowest physical activity. The most commonly reported activities were walking, bicycling, using stairs, and gardening. Walking was associated with a lower risk of hip replacement (adjusted RR 0.76 (95% CI 0.61, 0.94), specifically for women (adjusted RR 0.75 (95% CI 0.57, 0.98)). Conclusions In this population-based study of middle-aged men and women, leisure time physical activity showed no consistent overall relationship with incidence of severe knee or hip OA, defined as joint replacement due to OA, over 11 years. For women, higher leisure time physical activity may have a protective role for the incidence of hip replacement. Walking may have a protective role for hip replacement, specifically for women.

2010-01-01

Background The martial arts have emerged as common activities in the Canadian population, yet few studies have investigated the occurrence of associated injuries on a population basis. Methods We performed such an investigation and suggest potential opportunities for prevention. The data source was 14 years (1993 to 2006) of records from the Kingston sites of the Canadian Hospital Injury Reporting and Prevention Program (CHIRPP). Results 920 cases were identified. Incidence rates were initially estimated using census data as denominators. We then imputed annual injury rates per 10000 using a range of published estimates of martial arts participation available from a national survey. Rates of injury in males and females were 2300 and 1033 per 10000 (0.3% participation) and 575 and 258 per 10000 (1.2% participation). Injuries were most frequently reported in karate (33%) and taekwondo (14%). The most common mechanisms of injury were falls, throws and jumps (33%). Fractures (20%) were the most frequently reported type of injury and the lower limb was the most common site of injury (41%). Conclusions Results provide a foundation for potential interventions with a focus on falls, the use of weapons, participation in tournaments, as well as head and neck trauma. PMID:21192801

To help understand suicide among soldiers, we compared suicide events between active duty U.S. Army versus civilian decedents to identify differences and inform military prevention efforts. We linked 141 Army suicide records from 2005 to 2010 to National Violent Death Reporting System (NVDRS) data. We described the decedents' military background and compared their precipitators of death captured in NVDRS to those of demographically matched civilian suicide decedents. Both groups commonly had mental health and intimate partner precipitating circumstances, but soldier decedents less commonly disclosed suicide intent. © Published 2014.

Objectives To summarize the effectiveness of interventions targeting psychosocial factors to increase physical activity (PA) among ethnic minority adults and explore theory use in PA interventions. Methods Studies (N = 11) were identified through a systematic review and targeted African American/Hispanic adults, specific psychosocial factors, and PA. Data were extracted using a standard code sheet and the Theory Coding Scheme. Results Social support was the most common psychosocial factor reported, followed by motivational readiness, and self-efficacy, as being associated with increased PA. Only 7 studies explicitly reported using a theoretical framework. Conclusions Future efforts should explore theory use in PA interventions and how integration of theoretical constructs, including psychosocial factors, increases PA. PMID:25290599

In patients with tuberculosis, abnormal extrarenal production of 1,25-dihydroxyvitamin D3 by activated macrophages in granulomatous tissues may result in hypercalcaemia. More commonly reported in adults with active pulmonary tuberculosis, this complication may rarely occur in extrapulmonary tuberculosis, and children. The hypercalcaemia may be precipitated by usually recommended vitamin D and calcium supplementation in patients with tuberculosis. We report here an infant with tubercular meningitis who developed hypercalcaemia 12 days after starting routine vitamin D and calcium supplementation. This communication highlights the importance of close monitoring of calcium levels in patients with tuberculosis, especially if started on vitamin D and calcium replacement before anti-tubercular therapy.

Spontaneous subdural hematomas of arterial origin are rare with only a few published case reports in the literature. In the CT era, vessel imaging of extra-axial hematomas is not commonly performed. In this case report we present a patient with a large, spontaneous acute subdural hematoma that demonstrated active contrast extravasation from a small cortical vessel on CT angiography. During surgical evacuation the vessel was confirmed to be a small cortical artery that was bulging through the arachnoid membrane and bleeding into the subdural space. The historical, radiographic, and clinical aspects of this unusual cause of subdural hematoma are discussed. (c) 2010 Elsevier B.V. All rights reserved.

Low back pain is a primary health care utilization driver in the US population. Health care evaluation visits for low back pain are as common as medical evaluation for the common cold. Low back pain is the most common reason for reductions in activities of daily living and work activity in the general population. Although these statistics are compelling, in the military population, there is arguably a significantly greater economic impact on the military population, as the cost to train, retain, and deploy a service member is a tremendous cost. The current study retrospectively examines surgical outcomes, return to duty, and patient-centric outcomes among 82 active duty or reserve military patients who underwent an outpatient minimally invasive spine surgery Laminotomy Foraminotomy Decompression for the treatment of lumbar spinal stenosis in an ambulatory surgery center. Overall, our results indicate that within the 82 active duty military service members, 100% of the service members return to duty within 3 mo. Additionally, there was a significant reduction in self-reported pain and disability 12 mo postoperative, whereas the average length of surgery was 62 min with an average estimated blood loss of 30.64 mL. The current study indicates that minimally invasive procedures for the treatment of lumbar spinal stenosis in an ambulatory surgery center setting are an effective option for active duty servicemen to reduce return-to-duty rates and symptomatic back-related pain and disability.

It has been suggested that young people should develop competence in a variety of 'lifelong physical activities' to ensure that they can be active across the lifespan. The primary aim of this systematic review is to report the methodological properties, validity, reliability, and test duration of field-based measures that assess movement skill competency in lifelong physical activities. A secondary aim was to clearly define those characteristics unique to lifelong physical activities. A search of four electronic databases (Scopus, SPORTDiscus, ProQuest, and PubMed) was conducted between June 2014 and April 2015 with no date restrictions. Studies addressing the validity and/or reliability of lifelong physical activity tests were reviewed. Included articles were required to assess lifelong physical activities using process-oriented measures, as well as report either one type of validity or reliability. Assessment criteria for methodological quality were adapted from a checklist used in a previous review of sport skill outcome assessments. Movement skill assessments for eight different lifelong physical activities (badminton, cycling, dance, golf, racquetball, resistance training, swimming, and tennis) in 17 studies were identified for inclusion. Methodological quality, validity, reliability, and test duration (time to assess a single participant), for each article were assessed. Moderate to excellent reliability results were found in 16 of 17 studies, with 71% reporting inter-rater reliability and 41% reporting intra-rater reliability. Only four studies in this review reported test-retest reliability. Ten studies reported validity results; content validity was cited in 41% of these studies. Construct validity was reported in 24% of studies, while criterion validity was only reported in 12% of studies. Numerous assessments for lifelong physical activities may exist, yet only assessments for eight lifelong physical activities were included in this review. Generalizability of results may be more applicable if more heterogeneous samples are used in future research. Moderate to excellent levels of inter- and intra-rater reliability were reported in the majority of studies. However, future work should look to establish test-retest reliability. Validity was less commonly reported than reliability, and further types of validity other than content validity need to be established in future research. Specifically, predictive validity of 'lifelong physical activity' movement skill competency is needed to support the assertion that such activities provide the foundation for a lifetime of activity.

The assessment of physical activity and return to sport and exercise activities is an important component in the overall evaluation of outcome after autologous cartilage implantation (ACI). To identify the patient-report instruments that are commonly used in the evaluation of physical activity and return to sport after ACI and provide a critical analysis of these instruments from a rehabilitative perspective. A computerized search was performed in January 2013 and repeated in March 2013. Criteria for inclusion required that studies (1) be written in English and published between 1994 and 2013; (2) be clinical studies where knee ACI cartilage repair was the primary treatment, or comparison studies between ACI and other techniques or between different ACI generations; (3) report postoperative physical activity and sport participation outcomes results, and (4) have evidence level of I-III. Twenty-six studies fulfilled the inclusion criteria. Three physical activity scales were identified: the Tegner Activity Scale, Modified Baecke Questionnaire, and Activity Rating Scale. Five knee-specific instruments were identified: the Lysholm Knee Function Scale, International Knee Documentation Committee Score Subjective Form, Knee Injury and Osteoarthritis Outcome Score, Modified Cincinnati Knee Score, and Stanmore-Bentley Functional Score. Considerable heterogeneity exists in the reporting of physical activity and sports participation after ACI. Current instruments do not fulfill the rehabilitative needs in the evaluation of physical activity and sports participation.

Assess the agreement between commonly used self-report methods compared with objectively measured physical activity (PA) in defining the prevalence of individuals compliant with PA recommendations. Time spent in moderate and vigorous PA (MVPA) was measured at two time points in 1713 healthy individuals from nine European countries using individually calibrated combined heart rate and movement sensing. Participants also completed the Recent Physical Activity Questionnaire (RPAQ), short form of the International Physical Activity Questionnaire (IPAQ), and short European Prospective Investigation into Cancer and Nutrition Physical Activity Questionnaire (EPIC-PAQ). Individuals were categorized as active (e.g., reporting ≥150 min of MVPA per week) or inactive, based on the information derived from the different measures. Sensitivity and specificity analyses and Kappa statistics were performed to evaluate the ability of the three PA questionnaires to correctly categorize individuals as active or inactive. Prevalence estimates of being sufficiently active varied significantly (P for all <0.001) between self-report measures (IPAQ 84.2% [95% confidence interval {CI}, 82.5-85.9], RPAQ 87.6% [95% CI, 85.9-89.1], EPIC-PAQ 39.9% [95% CI, 37.5-42.1] and objective measure 48.5% [95% CI, 41.6-50.9]. All self-report methods showed low or moderate sensitivity (IPAQ 20.0%, RPAQ 18.7%, and EPIC-PAQ 69.8%) to correctly classify inactive people and the agreement between objective and self-reported PA was low (ĸ = 0.07 [95% CI, 0.02-0.12], 0.12 [95% CI, 0.06-0.18], and 0.19 [95% CI, 0.13-0.24] for IPAQ, RPAQ, and EPIC-PAQ, respectively). The modest agreement between self-reported and objectively measured PA suggests that population levels of PA derived from self-report should be interpreted cautiously. Implementation of objective measures in large-scale cohort studies and surveillance systems is recommended.

Chemical Functionalization of Plasmonic Surface Biosensors: A Tutorial Review on Issues, Strategies, and Costs

PubMed Central

2017-01-01

In an ideal plasmonic surface sensor, the bioactive area, where analytes are recognized by specific biomolecules, is surrounded by an area that is generally composed of a different material. The latter, often the surface of the supporting chip, is generally hard to be selectively functionalized, with respect to the active area. As a result, cross talks between the active area and the surrounding one may occur. In designing a plasmonic sensor, various issues must be addressed: the specificity of analyte recognition, the orientation of the immobilized biomolecule that acts as the analyte receptor, and the selectivity of surface coverage. The objective of this tutorial review is to introduce the main rational tools required for a correct and complete approach to chemically functionalize plasmonic surface biosensors. After a short introduction, the review discusses, in detail, the most common strategies for achieving effective surface functionalization. The most important issues, such as the orientation of active molecules and spatial and chemical selectivity, are considered. A list of well-defined protocols is suggested for the most common practical situations. Importantly, for the reported protocols, we also present direct comparisons in term of costs, labor demand, and risk vs benefit balance. In addition, a survey of the most used characterization techniques necessary to validate the chemical protocols is reported. PMID:28796479

Protozoan parasites infect and kill millions of people worldwide every year, particularly in developing countries where access to clean fresh water is limited. Among the most common are intestinal parasites, including Giardia lamblia and Entamoeba histolytica. These parasites wreak havoc on the epithelium lining the small intestines (G. lamblia) and colon (E. histolytica) causing giardiasis and amebiasis, respectively. In addition, there are less common but far more deadly pathogens such as Naegleria fowleri that thrive in warm waters and infect the central nervous systems of their victims via the nasal passages. Despite their prevalence and associated high mortality rates, there remains an unmet need to identify more effective therapeutics for people infected with these opportunistic parasites. To address this unmet need, we have surveyed plants and traditional herbal medicines known throughout the world to identify novel antiparasitic agents with activity against G. lamblia, E. histolytica, and N. fowleri. Herein, we report Larrea tridentata, known as creosote bush, as a novel source for secondary metabolites that display antiparasitic activity against all three pathogens. This report also characterizes the lignan compound classes, nordihydroguairetic acid and demethoxyisoguaiacin, as novel antiparasitic lead agents to further develop more effective drug therapy options for millions of people worldwide.

These parasites wreak havoc on the epithelium lining the small intestines (G. lamblia) and colon (E. histolytica) causing giardiasis and amebiasis, respectively. In addition, there are less common but far more deadly pathogens such as Naegleria fowleri that thrive in warm waters and infect the central nervous systems of their victims via the nasal passages. Despite their prevalence and associated high mortality rates, there remains an unmet need to identify more effective therapeutics for people infected with these opportunistic parasites. To address this unmet need, we have surveyed plants and traditional herbal medicines known throughout the world to identify novel antiparasitic agents with activity against G. lamblia, E. histolytica, and N. fowleri. Herein, we report Larrea tridentata, known as creosote bush, as a novel source for secondary metabolites that display antiparasitic activity against all three pathogens. This report also characterizes the lignan compound classes, nordihydroguairetic acid and demethoxyisoguaiacin, as novel antiparasitic lead agents to further develop more effective drug therapy options for millions of people worldwide.

Auditory phonological priming in children and adults during word repetition

NASA Astrophysics Data System (ADS)

Cleary, Miranda; Schwartz, Richard G.

2004-05-01

Short-term auditory phonological priming effects involve changes in the speed with which words are processed by a listener as a function of recent exposure to other similar-sounding words. Activation of phonological/lexical representations appears to persist beyond the immediate offset of a word, influencing subsequent processing. Priming effects are commonly cited as demonstrating concurrent activation of word/phonological candidates during word identification. Phonological priming is controversial, the direction of effects (facilitating versus slowing) varying with the prime-target relationship. In adults, it has repeatedly been demonstrated, however, that hearing a prime word that rhymes with the following target word (ISI=50 ms) decreases the time necessary to initiate repetition of the target, relative to when the prime and target have no phonemic overlap. Activation of phonological representations in children has not typically been studied using this paradigm, auditory-word + picture-naming tasks being used instead. The present study employed an auditory phonological priming paradigm being developed for use with normal-hearing and hearing-impaired children. Initial results from normal-hearing adults replicate previous reports of faster naming times for targets following a rhyming prime word than for targets following a prime having no phonemes in common. Results from normal-hearing children will also be reported. [Work supported by NIH-NIDCD T32DC000039.

Living with genital pain: Sexual function, satisfaction, and help-seeking among women living in Sweden.

PubMed

Thomtén, Johanna

2017-12-29

Background and aims Female genital pain is a debilitating problem that negatively affects several aspects of the life of women. Several studies present figures of prevalence indicating that the problem affects nearly 20% of young women. However, many women fail to consult health care and the estimated prevalence therefore remains insecure. Historically, genital pain was commonly viewed as either physiological or psychosexual. Although the current field of research and clinical expertise in general agree upon a biopsychosocial conceptualization, less is known about the manifestation of the problem in everyday life and the experience of seeking health care among afflicted women. The objectives of the present study was to examine genital pain in a general female population living in Sweden cross-sectionally in terms of prevalence, sexual function, sexual satisfaction and help seeking, and to identify possible predictors of genital pain among women. Methods The study was a population-based study using a postal questionnaire administered to 4052 women (age 18--35). Of these 944 (response rate: 23%) took part in the study. Results Genital pain of six months duration was reported by 16.1% of the women. Women with pain more commonly reported fungal infections, other pain problems, sexual dysfunctions and symptoms of anxiety than pain-free women and in addition lower sexual satisfaction. There were no differences in sexual frequency. Pain was most commonly reported during sexual intercourse, but many women also experienced pain during non-sexual activities, with pain durations of several hours after the pain eliciting activity was interrupted. Of those reporting pain, 50% had sought care for their pain. The most common was to counsel a doctor and to receive topical treatment. However, the experienced effects of the treatments were on average low. In the explanatory model, fungal infections, and sexual dysfunctions were associated with genital pain. Conclusions The study had a low response rate, but still indicates that genital pain is common and negatively affects several aspects of women' life, not just sexual activities. Although many women report pro-longed pain experiences, many fail to consult health care and among those who seek care the effects of treatment are on average poor. There are strong associations between sexual dysfunctions (lack of sexual arousal, vaginal muscle tension hindering intercourse) and genital pain that, based on previous findings in this field of research, might be viewed in terms of circular maintaining processes. Implications Female genital pain is not just limited to the sexual context, but often negatively affects several situations in women' life. The size of the problem calls for immediate development of preventive interventions and treatment programs that focus on sexual education and to encourage a healthy sexuality among women and their partners. There is a need to identify methods in order to assemble evidence based interventions of female genital pain. Such methods are currently lacking, resulting in poor treatment options for women with pain.

Role of Microglia Disturbances and Immune-Related Marker Abnormalities in Cortical Circuitry Dysfunction in Schizophrenia

PubMed Central

Volk, David W.

2017-01-01

Studies of genetics, serum cytokines, and autoimmune illnesses suggest that immune-related abnormalities are involved in the disease process of schizophrenia. Furthermore, direct evidence of cortical immune activation, including markedly elevated levels of many immune-related markers, have been reported in the prefrontal cortex in multiple cohorts of schizophrenia subjects. Within the prefrontal cortex in schizophrenia, deficits in the basilar dendritic spines of layer 3 pyramidal neurons and disturbances in inhibitory inputs to pyramidal neurons have also been commonly reported. Interestingly, microglia, the resident immune-related cells of the brain, also regulate excitatory and inhibitory input to pyramidal neurons. Consequently, in this review, we describe the cytological and molecular evidence of immune activation that has been reported in the brains of individuals with schizophrenia and the potential links between these immune-related disturbances with previously reported disturbances in pyramidal and inhibitory neurons in the disorder. Finally, we discuss the role that activated microglia may play in connecting these observations and as potential therapeutic treatment targets in schizophrenia. PMID:28007586

Electroconvulsive therapy for depression in a patient with an Inspire hypoglossal nerve stimulator device for obstructive sleep apnea: A case report.

PubMed

Mingo, Katie; Kominsky, Alan

2018-04-19

METHODS: This is a case report of a patient who underwent placement and initiation of a hypoglossal nerve stimulator device in the context of receiving electroconvulsive therapy for bipolar depression between February and September 2016. To our knowledge, this has not yet been reported in the literature. Outcome measurements included successful device activation and successful device use throughout electroconvulsive therapy. The patient underwent successful device implantation, activation, and use without disruption throughout electroconvulsive therapy sessions. No special device deactivation was required during electroconvulsive therapy sessions. Obstructive sleep apnea is a common disorder that causes significant reduction in quality of life and is an independent risk factor for multiple comorbidities. Electroconvulsive therapy is an established treatment for medication-refractory depression with minimal risk in most patient populations. This is the first report in the literature of a patient undergoing ECT for bipolar depression with recent activation of Inspire hypoglossal nerve stimulator who had no disruption in the function of his implanted device.

Physical activity (PA) programs are a promising strategy to promote positive youth development (PYD). It is not known if published reports provide sufficient information to promote the implementation of effective PYD in indigenous youth. The purpose of this study was to assess the extent to which published literature on PA programs that promote PYD in indigenous youth report on RE-AIM (reach, effectiveness, adoption, implementation, maintenance) indicators. A systematic literature search was conducted to identify articles reporting on PA programs that promote PYD in indigenous youth. The search yielded 8084 articles. A validated 21-item RE-AIM abstraction tool assessing internal and external validity factors was used to extract data from 10 articles meeting eligibility criteria. The most commonly reported dimensions were effectiveness (73 %), adoption (48 %), and maintenance (43 %). Reach (34 %) and implementation (30 %) were less often reported. Published research provides insufficient information to inform real-world implementation of PA programs to promote PYD in indigenous youth.

OBJECTIVES: This study was designed to assess the physical activity practice among type 2 diabetic patients in the United Arab Emirates (UAE). METHODS: This is a cross-sectional study of type 2 diabetic patients who participated in the outpatient clinics in Al-Ain District, during 2006. The patients completed an interviewer-administered questionnaire, and measurements of blood pressure, body mass index, body fat, abdominal circumference, glycemic control (HbA1c), and fasting lipid profile. RESULTS: Of the 390 patients recruited, only 25% reported an increase in their physical activity levels following the diagnosis of diabetes, and only 3% reported physical activity levels that meet the recommended guidelines. More than half of the study subjects had uncontrolled hypertension (53%) and unacceptable lipid profiles; 71% had a high low-density lipoprotein (LDL), 73% had low high-density lipoprotein (HDL), and 59% had hypertriglyceridemia. Forty-four percent were obese and a further 34% were overweight. Abdominal obesity was also common (59%). Only 32% had an acceptable glycemic control. CONCLUSIONS: The physical activity practice of type 2 diabetic patients in the UAE is largely inadequate to meet the recommended level necessary to prevent or ameliorate diabetic complications. Interventions aiming at overcoming the barriers to physical activity are urgently needed. PMID:20043039

Rubella virus is involved in the pathogenesis of Fuchs heterochromic uveitis and almost all cases in Europe show an active antibody production in the aqueous humor against rubella virus. Herein we report a case of a fully vaccinated patient with common variable immunodeficiency who developed unilateral Fuchs heterochromic uveitis secondary to rubella virus which was proven by intraocular fluid examination. Awareness of rubella associated anterior uveitis should remain also in vaccinated patients, especially those without a fully competent immune system.

To analyze the contents and formats of general self-reported questionnaires on disability that are designed for and/or are widely applied in the elderly population to depict a complete picture of this field and help researchers to choose proper tools more efficiently. A broad systematic literature search was performed in September 2013 and included the following databases: MEDLINE, EMBASE, CINAHL, PsycINFO, and PROQOLID. The publication language was limited to English and Chinese. Two review authors independently performed the study selection and data extraction. All of the included instruments were extracted and classified using the International Classification of Functioning, Disability, and Health framework. Of 5569 articles retrieved from the searches and 156 articles retrieved from the pearling, 22 studies (including 24 questionnaires) fulfilled the inclusion criteria. From these, 42 different domains and 458 items were extracted. The most frequently used questionnaire was the Barthel Index followed by the Lawton and Brody Instrumental Activities of Daily Living Scale and the Katz Index of Activities of Daily Living, respectively. The contents and formats of the questionnaires varied considerably. Activities and participation were the most commonly assessed dimensions. In addition, the Activities of Daily Living, mobility and the Instrumental Activities of Daily Living Scale were the most common domains assessed among the included questionnaires. Among the 24 included questionnaires, the most frequently used questionnaires were the Barthel Index, Lawton and Brody Instrumental Activities of Daily Living Scale, and Katz Index of Activities of Daily Living. The content and format of the questionnaires varied considerably, but none of the questionnaires covered all essential dimensions of the International Classification of Functioning, Disability, and Health framework.

Violence is a significant public health issue with far-reaching implications for the health of individuals and their communities. Our objective was to describe trends in violence-related training in family medicine residency programs since the last national survey was conducted in 1997. Surveys were sent to 337 US family medicine residency programs with the program director having active Society of Teachers of Family Medicine (STFM) membership. Measures included residency setting and characteristics, violence-related curricular content, teaching techniques and personnel, timing of content, and impact of changes in Residency Review Committee (RRC) and Accreditation Council for Graduate Medical Education (ACGME) requirements. Descriptive statistics and bivariate analyses comparing measures across time were used. A total of 201 (60%) surveys were completed. The most common violence curricula was child (83%) and elder abuse (76%), and the most common teachers of violence-related content were family physicians, psychologists, and social workers. The most common teaching methods were clinical precepting (94%), lectures (90%), case vignettes (71%), and intimate partner violence (IPV) shelter experiences (67%). ACGME and RRC changes were not reflected in self-reported measures of curricular emphasis or time. Violence curricular content and number of hours has been constant in family medicine residencies over time. An increase in the reported use of active learning strategies was identified as a trend across surveys. Next steps for violence curricula involve assessment of residents' competency to identify and intervene in violence.

The Active Healthy Kids Canada (AHKC) Report Card on Physical Activity for Children and Youth has been effective in powering the movement to get kids moving by influencing priorities, policies, and practice in Canada. The AHKC Report Card process was replicated in 14 additional countries from 5 continents using 9 common indicators (Overall Physical Activity, Organized Sport Participation, Active Play, Active Transportation, Sedentary Behavior, Family and Peers, School, Community and Built Environment, and Government Strategies and Investments), a harmonized process and a standardized grading framework. The 15 Report Cards were presented at the Global Summit on the Physical Activity of Children in Toronto on May 20, 2014. The consolidated findings are summarized here in the form of a global matrix of grades. There is a large spread in grades across countries for most indicators. Countries that lead in certain indicators lag in others. Overall, the grades for indicators of physical activity (PA) around the world are low/poor. Many countries have insufficient information to assign a grade, particularly for the Active Play and Family and Peers indicators. Grades for Sedentary Behaviors are, in general, better in low income countries. The Community and Built Environment indicator received high grades in high income countries and notably lower grades in low income countries. There was a pattern of higher PA and lower sedentary behavior in countries reporting poorer infrastructure, and lower PA and higher sedentary behavior in countries reporting better infrastructure, which presents an interesting paradox. Many surveillance and research gaps and weaknesses were apparent. International cooperation and cross-fertilization is encouraged to tackle existing challenges, understand underlying mechanisms, derive innovative solutions, and overcome the expanding childhood inactivity crisis.

Ganoderma genus comprises one of the most commonly studied species worldwide, Ganoderma lucidum. However, other Ganoderma species have been also reported as important sources of bioactive compounds. Polysaccharides are important contributors to the medicinal properties reported for Ganoderma species, as demonstrated by the numerous publications, including reviews, on this matter. Yet, what are the chemical features of Ganoderma polysaccharides that have bioactivity? In the present manuscript, the chemical features of Ganoderma polysaccharides with reported antioxidant, antitumor and antimicrobial activities (the most studied worldwide) are analyzed in detail. The composition of sugars (homo- versus hetero-glucans and other polysaccharides), type of glycosidic linkages, branching patterns, and linkage to proteins are discussed. Methods for extraction, isolation and identification are evaluated and, finally, the bioactivity of polysaccharidic extracts and purified compounds are discussed. The integration of data allows deduction of structure-activity relationships and gives clues to the chemical aspects involved in Ganoderma bioactivity. Copyright © 2014 Elsevier Ltd.

Trials on diet and physical activity in pregnancy report on various outcomes. We aimed to assess the variations in outcomes reported and their quality in trials on lifestyle interventions in pregnancy. We searched major databases without language restrictions for randomized controlled trials on diet and physical activity-based interventions in pregnancy up to March 2015. Two independent reviewers undertook study selection and data extraction. We estimated the percentage of papers reporting 'critically important' and 'important' outcomes. We defined the quality of reporting as a proportion using a six-item questionnaire. Regression analysis was used to identify factors affecting this quality. Sixty-six randomized controlled trials were published in 78 papers (66 main, 12 secondary). Gestational diabetes (57.6%, 38/66), preterm birth (48.5%, 32/66) and cesarian section (60.6%, 40/66), were the commonly reported 'critically important' outcomes. Gestational weight gain (84.5%, 56/66) and birth weight (87.9%, 58/66) were reported in most papers, although not considered critically important. The median quality of reporting was 0.60 (interquartile range 0.25, 0.83) for a maximum score of one. Study and journal characteristics did not affect quality. Many studies on lifestyle interventions in pregnancy do not report critically important outcomes, highlighting the need for core outcome set development. © 2017 Japan Society of Obstetrics and Gynecology.

Interpreting serum risperidone concentrations.

PubMed

Boerth, Joel M; Caley, Charles F; Goethe, John W

2005-02-01

Risperidone is an atypical antipsychotic commonly used for treatment of schizophrenia and other psychotic disorders. Although therapeutic drug monitoring is not routine for any of the atypical antipsychotics, serum antipsychotic concentrations are measured routinely to assess treatment nonadherence. In humans, risperidone is metabolized by cytochrome P450 2D6 to 9-hydroxyrisperidone; together these constitute the active moiety. Dose-proportional increases in serum concentrations have not been reported for the parent drug, but have been reported for 9-hydroxyrisperidone and the active moiety (i.e., the combined concentrations of risperidone and 9-hydroxyrisperidone). We describe a 34-year-old Caucasian man of Sicilian descent with a history of schizophrenia, disorganized type. He was suspected to be noncompliant with his risperidone therapy. Initially, active moiety risperidone concentrations increased linearly with prescribed dosage increases. However, with continued increases, active moiety concentrations adjusted downward and remained 17-36% below anticipated levels. We propose a method for estimating target active moiety concentrations of risperidone based on dosage-a method that may be used to guide clinicians in assessing nonadherence to risperidone treatment.

While adding the structural features that are more favored by on-target activity is the more common strategy in selectivity optimization, the opposite strategy of subtracting the structural features that contribute more to off-target activity can also be very effective. Reported here is our successful effort of improving the kinase selectivity of type II maternal embryonic leucine zipper kinase inhibitors by applying these two complementary approaches together, which clearly demonstrates the powerful synergy between them.

To examine if there is a difference in possible sleep bruxism activity (SB) in subjects with or without attrition-type tooth wear. Sixteen individuals with pronounced attritional-type tooth wear were compared with sex and aged matched controls without tooth wear by means of measurement of electromyographic (EMG) activity during a minimum of four consecutive nights of sleep. Mean age and range for the study- and control- group was 23.7 years (range 19.9-28.5) and 23.6 years (range 20.3-27.9), respectively. There were 11 females and five males in each of the two groups. The attrition group presented incisal/occlusal attrition wear into dentin and matching wear facets between opposing anterior teeth. The controls had negligible signs of incisal/occlusal wear and a minimal number of matching wear facets. The prevalence of both self-reported and partner-reported SB was significantly more common in the attrition group compared to the controls (P=0.04 and P=0.007, respectively). Self-reported morning facial pain was similarly more common in the attrition group (P=0.014). Maximum opening capacity, number of muscles painful to palpation, salivary flow rate and buffering capacity were not significantly different between the groups. Interestingly, none of the measures of jaw muscle EMG activity during sleep, as recorded by the portable EMG equipment, differed significantly between the attrition group and the matched controls (P>0.05). The results from this exploratory study suggest that there is no difference in EMG activity between subjects with and without attrition-type tooth wear. Further research is needed in order to substantiate these preliminary findings. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Sexual dysfunction is a common side effect of many antidepressants, especially those that increase serotonin. Many strategies have been reported to assist patients in minimizing impairment, with variable degrees of success. One of the newer approaches is to augment with phosphodiesterase type-5 inhibitors. Our report using the most recently released agent in this class, tadalafil is the first demonstrating potential benefit in women. We report here of three women who derived benefit from using 20 mg of tadalafil before anticipated sexual activity to reverse medication-induced sexual dysfunction. Tadalafil utility was maintained over time and was well tolerated.

Hansen, Colby; Godfrey, Bradeigh; Wixom, Jody; McFadden, Molly

2015-01-01

To assess the incidence and severity of self-reported hyperhidrosis in patients with amputation and understand its effects on prosthetic fit or function, a cross-sectional survey of patients at two amputee clinics was performed. Responses from 121 subjects with lower-limb amputation were analyzed. Of these subjects, 66% reported sweating to a degree that it interfered with daily activities, as measured by the Hyperhidrosis Disease Severity Scale. There was a significant association between sweating and interference with prosthetic fit and function. Sweating was more severe in cases of transtibial amputations, patients under the age of 60, warm weather, and vigorous activity. There was no relationship between severity of sweating and time since amputation, etiology of amputation, duration of daily prosthetic use, or reported ability to perform functional tasks. Subjects reported trying multiple interventions, but the self-reported effectiveness of these treatments was low. Hyperhidrosis, a common problem associated with prosthetic usage, varies in severity and often interferes with daily activities. Sweating severity is associated with poor prosthetic fit and function. Risk factors include younger age and transtibial amputation status. Treatment strategies generally lack efficacy. The results of this study may provide guidance for future interventions and treatment options.

To examine the associations between potential social ecological correlates and self-reported short physical activity breaks during work hours (defined as any interruption in sitting time during a typical work hour) among a sample of employees who commonly sit for working tasks. 801 employed adults aged 18-70 years from metropolitan Melbourne, Australia were surveyed in 2009 about their short physical activity breaks from sitting during work hours and potential social ecological correlates of this behaviour. Men reported significantly more short physical activity breaks per work hour than did women (2.5 vs. 2.3 breaks/h, p=0.02). A multivariable linear regression analysis adjusting for clustering and meeting the public health physical activity recommendations showed that the factors associated with frequency of short physical activity breaks per work hour were perceptions of lack of time for short physical activity breaks for men (-0.31 breaks/h, 95% confidence intervals [CI] -0.52, -0.09) and lack of information about taking short physical activity breaks for women (-0.20 breaks/h, CI -0.47, -0.05). These findings suggest that providing male employees with support for short physical activity breaks during work hours, and female employees with information on benefits of this behaviour may be useful for reducing workplace sedentary time.

Nassiri-Kashani, Mansour; Nassiri-Kashani, Mohammad Hassan; Ghafari, Mostafa

2016-01-01

Background: Occupational contact dermatitis, especially in hand, is one of the most common occupational disorders. The present study aimed at evaluating patients with occupational allergic contact dermatitis (ACD) caused by common allergens based on occupation type and disease history. Methods: This cross-sectional study aimed at evaluating the data of the patients with probable diagnosis of ACD in Center for Research and Training in Skin Diseases and Leprosy (CRTSDL) in Iran. In the present study, 946 patients were assessed from different regions of Iran. One hundred fifty-one cases with positive patch test and relevant exposure were entered into the study; data related to their occupation and disease activity history were evaluated and recorded. Then, factors related to disease activity history were assessed considering the occupational groups and common exposures. Results: Nickel sulphate was the most common allergen in the 151 patients. Disease activity was constant in 29.8% of the patients; it increased in 27.8%, and decreased just before doing the patch test in 42.4%. Of the patients, 52.3% were getting worse during the working days. Occupational groups were significantly different in age and gender. Disease duration was also different in the occupational groups (p=0.001). The least disease duration was observed in healthcare workers, and the most in service workers. Lesions in the foot were related to period of employment. In administrative work group, (teachers, technicians and housewives) disease activity was decreased in the most cases, while it was increased in most patients of service workers (p=0.086). Conclusion: The present study, similar to previous reports, revealed that nickel sulphate is the most common allergen in ACD cases. Moreover, it was found that the symptoms of disease activity remained constant or increased in a significant proportion of the cases during the working days. Therefore, these workers should seriously follow up on this matter and change their occupation, or limit the exposure to allergens.

The purpose of this study was to describe common clinical practices of manual therapists (MTs) in the Netherlands for infants with indications of upper cervical dysfunction (UCD). A prospective observational cohort study was conducted to gain insight into characteristics, reasons for seeking care, and common clinical practice for infants (<27 weeks) with indications of UCD, referred to MTs. Pre- and posttreatment self-reported questionnaires were used to collect data from parents and MTs. Parents reported on infant characteristics and perceived effect of treatment. Manual therapists reported on diagnostics, therapeutic procedures, and outcomes. Between 2006 and 2007, data regarding 307 referred infants (mean age: 11.2 weeks) were collected by parents and 42 MTs. The most frequent reasons for seeking care were positional preference, restlessness, and/or abnormal head position. Manual therapists observed active, spontaneous, and provoked mobility and passive upper cervical mobility. Of the 307 infants, 295 were diagnosed with UCD based on positive outcomes on the flexion-rotation test and/or lateral flexion test. After treatment with mobilization techniques, positive outcomes on the flexion-rotation test decreased from 78.8% to 6.8%. For the lateral flexion test, the positive outcomes decreased from 91.5% to 6.2%. All parents perceived positive treatment effects. No serious adverse events were reported during this study. This is the first study to describe common clinical practice for infants referred for manual therapy. Infants with UCD were treated mainly with upper cervical mobilization techniques, and the greatest perceived effect was observed after approximately 2 treatment sessions. Copyright © 2018.

Purpose of Review The goal of this review is to present an updated summary of the natural history of major childhood and adult food allergies and report recent advances in potential treatments for food allergy. Recent Findings The most common childhood food allergies are typically outgrown by adolescence or adulthood. However, peanut/tree nut allergies appear to more commonly persist into adulthood. Adults can develop new IgE-mediated food allergies; the most common is oral allergy syndrome. There are multiple different approaches being tried as possible treatments for food allergy. Summary The prevalence of food allergy appears to be increasing but the varied approaches to treatment are being actively pursued such that an approved modality may not be too far in the future.

Injuries and fatalities among participants of adventure tourism activities have the potential to seriously impact on New Zealand's tourism industry. However, the absence of statistics for tourist accidents in New Zealand, and the lack of detailed academic research into adventure tourism safety, means the extent of the problem is unknown. The aims of the present study were to determine the incidence of client injuries across a range of adventure tourism activity sectors, and to identify common accident events and contributory risk factors. A postal questionnaire survey of New Zealand adventure tourism operators was used. Operators were asked to provide information related to their business; the number of recorded client injuries during the preceding 12 month period, January to December 1998; common accident and injury events associated with their activity; and perceived risk factors for accidents in their sector of the adventure tourism industry. The survey was responded to by 142 New Zealand adventure tourism operators. The operators' reported client injury experience suggests the incidence of serious client injuries is very low. Highest client injury incidence rates were found for activities that involved the risk of falling from a moving vehicle or animal (e.g., cycle tours, quad biking, horse riding, and white-water rafting). Slips, trips, and falls on the level were common accident events across most sectors of the industry. Perceived accident/incident causes were most commonly related to the client, and in particular, failure to attend to and follow instructions. The prevalence of client injuries in activity sectors not presently covered by government regulation, suggests policy makers should look again at extending codes of practice to a wider range of adventure tourism activities. Further research considering adventure tourism involvement in overseas visitor hospitalized injuries in New Zealand, is currently in progress. This will provide supporting evidence for the risk associated with participation in a range of commercial and independently undertaken adventure activities.

Factors influencing self-reported vision-related activity limitation in the visually impaired.

The use of patient-reported outcome (PRO) measures to assess self-reported difficulty in visual activities is common in patients with impaired vision. This study determines the visual and psychosocial factors influencing patients' responses to self-report measures, to aid in understanding what is being measured. One hundred visually impaired participants completed the Activity Inventory (AI), which assesses self-reported, vision-related activity limitation (VRAL) in the task domains of reading, mobility, visual information, and visual motor tasks. Participants also completed clinical tests of visual function (distance visual acuity and near reading performance both with and without low vision aids [LVAs], contrast sensitivity, visual fields, and depth discrimination), and questionnaires assessing depressive symptoms, social support, adjustment to visual loss, and personality. Multiple regression analyses identified that an acuity measure (distance or near), and, to a lesser extent, near reading performance without LVAs, visual fields, and contrast sensitivity best explained self-reported VRAL (28%-50% variance explained). Significant psychosocial correlates were depression and adjustment, explaining an additional 6% to 19% unique variance. Dependent on task domain, the parameters assessed explained 59% to 71% of the variance in self-reported VRAL. Visual function, most notably acuity without LVAs, is the best predictor of self-reported VRAL assessed by the AI. Depression and adjustment to visual loss also significantly influence self-reported VRAL, largely independent of the severity of visual loss and most notably in the less vision-specific tasks. The results suggest that rehabilitation strategies addressing depression and adjustment could improve perceived visual disability.

Fatigue is a common symptom in patients with pulmonary arterial hypertension (PAH); however, the impact of fatigue on daily physical activity in PAH is unknown. Accelerometry is a validated measure for assessing physical activity. We hypothesized that patients with PAH reporting higher levels of fatigue would have lower daily physical activity measured by accelerometry. We performed a prospective cohort study of 15 women with PAH. On day 1, subjects completed the Multidimensional Fatigue Inventory (MFI), the United States Cambridge Pulmonary Hypertension Outcome Review (US CAMPHOR), and a 6-min walk test. Subjects wore the accelerometer on their dominant hip and completed an activity diary for 7 days. On day 15, subjects repeated the MFI and the US CAMPHOR, and then wore the accelerometer and completed an activity diary for an additional 7 days. All multivariate analyses were adjusted for age, BMI, and PAH type. The mean age was 50.5 years, and 53% had idiopathic or heritable PAH. During the 2 weeks, subjects were mostly sedentary (85% of the time), although 10% of their time was spent performing low-level activity. Lower average daily counts were associated with worse self-reported energy levels, whereas less day-to-day physical activity variability was associated with more self-reported mental fatigue, physical fatigue, and total activity. Higher percentage of activity bouts was also associated with worse energy. Women with PAH may spend most of their time being sedentary, and lower self-reported energy levels are associated with less daily activity. Interventions to improve symptoms such as fatigue may also increase physical activity levels in PAH. Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc.

Detection of Protein Interactions in T3S Systems Using Yeast Two-Hybrid Analysis.

PubMed

Nilles, Matthew L

2017-01-01

Two-hybrid systems, sometimes termed interaction traps, are genetic systems designed to find and analyze interactions between proteins. The most common systems are yeast based (commonly Saccharomyces cerevisae) and rely on the functional reconstitution of the GAL4 transcriptional activator. Reporter genes, such as the lacZ gene of Escherichia coli (encodes β-galactosidase), are placed under GAL4-dependent transcriptional control to provide quick and reliable detection of protein interactions. In this method the use of a yeast-based two-hybrid system is described to study protein interactions between components of type III secretion systems.

Marijuana, prepared from the plant Cannabis sativa, is the most widely used illicit drug in the United States. Marijuana use has been associated with adverse psychosocial and health effects, including effects on oral tissues. Periodontal literature has limited references to the periodontal effects of cannabis use. In this report, we present two cases of marijuana-associated gingival enlargement and review the literature on oral complications of marijuana use. Two asymptomatic males, aged 23 and 42 years, presented independently for oral prophylaxis. Both had an unremarkable medical history and related a history of significant marijuana use of 2-16 years duration. Common findings following oral and periodontal examination were nicotinic stomatitis-like lesions, uvulitis and gingival enlargement. Marginal and papillary gingiva of the anterior dentition were the areas primarily affected by gingival enlargement, while some of these areas exhibited a nodular or "pebbly" appearance. Marijuana-associated gingival enlargement was diagnosed in the reported cases. A review of the literature revealed two other reports of marijuana-associated gingival enlargement, all in young adult males with chronic (2 or more years) cannabis use. These authors reported a resemblance to phenytoin-induced enlargement. Biochemical similarities between phenytoin and cannabis active compounds suggest possible common pathogenetic mechanisms. Uvulitis and nicotinic stomatitis appear to be the two most common of the several oral manifestations of marijuana use. Chronic marijuana use may result in gingival enlargement with clinical characteristics similar to phenytoin-induced enlargement.

Objective Spiritual distress is common in the ICU, and spiritual care providers are often called upon to provide care for patients and their families. Our goal was to evaluate the activities spiritual care providers’ conduct to support patients and families, and whether those activities are associated with family satisfaction with ICU care. Design Prospective cohort study. Setting 350-bed, 65-ICU bed tertiary care teaching hospital. Subjects Spiritual care providers and family members of patients who died in the ICU or within 30 hours of transfer from the ICU. Measurements Spiritual care providers completed surveys reporting their activities. Family members completed validated measures of satisfaction with care and satisfaction with spiritual care. Clustered regression was used to assess the association between activities completed by spiritual care providers and family ratings of care. Results Of 494 eligible patients, 275 family members completed surveys (response rate, 56%). Fifty-seven spiritual care providers received surveys relating to 268 patients, completing 285 surveys for 244 patients (response rate, 91%). Spiritual care providers commonly reported activities related to supporting religious and spiritual needs (>=90%) and providing support for family feelings (90%). Discussions about the patient’s wishes for end-of-life care and a greater number of spiritual care activities performed were both associated with increased overall family satisfaction with ICU care (p<0.05). Discussions about a patient’s end-of-life wishes, preparation for a family conference, and total number of activities performed were associated with improved family satisfaction with decision-making in the ICU (p<0.05). Conclusions Spiritual care providers engage in a variety of activities with families of ICU patients; several are associated with increased family satisfaction with ICU care in general and decision-making in the ICU specifically. These findings provide insight into spiritual care provider activities and provide guidance for interventions to improve spiritual care delivered to families of critically ill patients.

The prevalence of swallowing disorders (dysphagia) following a total laryngectomy remains unknown, with estimates varying from 17 to 70%. The primary aim of this study was to investigate the prevalence and nature of self-reported dysphagia following a total laryngectomy across New South Wales (NSW), Australia. A secondary aim was to document the effect of dysphagia on the respondents' social activities and participation. A questionnaire battery, with a prepaid envelope for return, was sent to all laryngectomy members (n = 197) of the Laryngectomy Association of NSW. One hundred twenty questionnaires (61%) were completed and returned. Dysphagia was self-reported by 71.8% of the cohort. In this cohort with dysphagia, the most commonly reported features included an increased time required to swallow, a need for fluids to wash down a bolus, and avoidance of certain food consistencies. Severe distress was reportedly associated with dysphagia for 39.7% of these respondents and prevented 57% of them from participating in social activities, such as eating at friends' houses and/or at restaurants. The prevalence of self-reported dysphagia following total laryngectomy in this Australian study was 72%. Dysphagia can result in laryngectomies making significant changes to their diets and it has a marked impact on their activities and social participation.

Parents can influence the health behaviors of their children by engaging in supportive behaviors (e.g., playing outside with their child, limiting recreational screen time). How, and the extent to which parents engage in supportive behaviors may be influenced by perceived barriers. The purpose of this study is to explore whether the frequency, and types, of barriers to providing parental support are dependent on the type of child health behavior being supported (i.e., physical activity, recreational screen time reduction, healthy eating, and sleep). Study participants were 1140 Ontario parents with at least one child under the age of 18 who completed a Computer Assisted Telephone Interview (CATI) survey about parental support behaviors. Open-ended responses about perceived barriers to parental support were coded, and aggregated to meta-categories adopted from the social-ecological model (i.e., individual child, individual parent, interpersonal, environmental). Freidman rank sum tests were used to assess differences across child behaviors. Wilcoxon rank sum tests with Bonferroni adjustments were used as a post hoc test for significant Freidman results. There were more barriers reported for supporting physical activity than for any other child behavior (ps < .01, As ≥ .53). Parents reported more parent level and environmental level barriers to supporting child physical activity versus other behaviors (ps < .001, As ≥ .55), child level barriers were more frequently reported for supporting healthy eating and sleep (ps < .001, As ≥ .57), and interpersonal barriers were more frequently reported for supporting recreational screen time reduction (ps < .001, As ≥ .52). Overall, parents reported more child and parent level barriers versus interpersonal and environmental barriers to supporting child health. Parents experience a variety of barriers to supporting their children's health behaviors. Differences in types of barriers across child health behaviors emerged; however, some frequently reported barriers (e.g., child preferences) were common across behaviors. Interventions promoting parental support should consider strategies that can accommodate parents' busy schedules, and relate to activities that children find enjoyable. Creating supportive environments that help facilitate support behaviors, while minimizing parent level barriers, may be of particular benefit. Future research should explore the impact of barriers on parental support behaviors, and effective strategies for overcoming common barriers.

Characterizing high-velocity angular vestibulo-ocular reflex function in service members post-blast exposure.

2011-02-01

Blasts (explosions) are the most common mechanism of injury in modern warfare. Traumatic brain injury (TBI) and dizziness are common sequelae associated with blasts, and many service members (SMs) report symptoms worsen with activity. The purpose of this study was to measure angular vestibulo-ocular reflex gain (aVOR) of blast-exposed SMs with TBI during head impulse testing. We also assessed their symptoms during exertion. Twenty-four SMs recovering from TBI were prospectively assigned to one of two groups based on the presence or absence of dizziness. Wireless monocular scleral search coil and rate sensor were used to characterize active and passive yaw and pitch head and eye rotations. Visual analog scale (VAS) was used to monitor symptoms during fast walking/running. For active yaw head impulses, aVOR gains were significantly lower in the symptomatic group (0.79 ± 0.15) versus asymptomatic (0.87 ± 0.18), but not for passive head rotation. For pitch head rotation, the symptomatic group had both active (0.915 ± 0.24) and passive (0.878 ± 0.22) aVOR gains lower than the asymptomatic group (active 1.03 ± 0.27, passive 0.97 ± 0.23). Some SMs had elevated aVOR gain. VAS scores for all symptoms were highest during exertion. Our data suggest symptomatic SMs with TBI as a result of blast have varied aVOR gain during high-velocity head impulses and provide compelling evidence of pathology affecting the vestibular system. Potential loci of injury in this population include the following: disruption of pathways relaying vestibular efference signals, differential destruction of type I vestibular hair cells, or selective damage to irregular afferent pathways-any of which may explain the common discrepancy between reports of vestibular-like symptoms and laboratory testing results. Significantly reduced pitch aVOR in symptomatic SMs and peak symptom severity during exertional testing support earlier findings in the chronic blast-exposed active duty SMs.

Findings are reported on the first two years of an active injury surveillance project designed to test the utility of active injury investigations in identifying causes of injury among a large cohort of carpenters who did residential building and drywall installation. Occupational Safety and Health Administration recordable injuries were reported by participating contractors. Injured union carpenters were interviewed by experienced journeymen trained in a standard questionnaire protocol. Enumeration of workers and hours worked were provided by the union. These data allowed the definition of a dynamic cohort of 4429 carpenters, their hours worked, detailed information on the circumstances surrounding recordable injuries, and possible preventive measures from the perspectives of the injured worker and an experienced journeyman investigator. The overall estimated injury rate (16.9 per 200,000 hours worked) was considerably higher than recent Bureau of Labor Statistics rates despite less than complete ascertainment of injuries. Injuries most commonly involved being struck by or against something, manual materials handling injuries, and falls. Manual materials handling injuries often involved very heavy objects or tasks and were injuries carpenters most often reported needs for adequate help and coordinated team work to prevent. Falls from heights occurred from a variety of surfaces and were not just injuries of inexperience. Carpenters reported the need for more attention to common fall protection practices, such as the use of more toe boards and guardrails. Poor housekeeping was involved in the majority of same level falls, as well as some manual materials handling injuries.

Children (5-15 years) with active epilepsy were screened using the parent-report (n=69) and self-report (n=48) versions of the Spence Children's Anxiety Scale (SCAS) and the self-report version of the Children's Depression Inventory (CDI) (n=48) in a population-based sample. A total of 32.2% of children (self-report) and 15.2% of children (parent-report) scored ≥1 SD above the mean on the SCAS total score. The subscales where most difficulty were reported on parent-report were Physical Injury and Separation Anxiety. There was less variation on self-report. On the CDI, 20.9% of young people scored ≥1 SD above the mean. Children reported significantly more symptoms of anxiety on the SCAS total score and three of the subscales (p<.05). There was a significant effect on the SCAS total score of respondents by seizure type interaction, suggesting higher scores on SCAS for children with generalized seizures on self- but not parent-report. Higher CDI scores were significantly associated with generalized seizures (p>.05). Symptoms of anxiety were more common based on self-report compared with parent-report. Children with generalized seizures reported more symptoms of depression and anxiety. Copyright © 2015 Elsevier Inc. All rights reserved.

With over a 100 different serotypes, the human rhinovirus (HRV) is the major aetiological agent for the common cold, for which only symptomatic treatment is available. HRV maturation and replication is entirely dependent on the activity of a virally encoded 3C protease that represents an attractive target for the development of therapeutics to treat the common cold. Although a variety of small molecules and peptidomimetics have been found to inhibit HRV 3C protease, no universally compatible assay exists to reliably quantify the activity of the enzyme in vitro. Herein we report the development of a universal and robust solid phase peptide assay that utilizes the full HRV-14 3C protease recognition sequence and the release of 5(6)-carboxyfluorescein to sensitively quantify protease activity. This novel assay overcomes several limitations of existing assays allowing for the simple and efficient analysis of HRV-14 3C protease activity facilitating both high-throughput screening and the accurate kinetic study of HRV-14 3C protease inhibitors.

2013-03-01

Population surveys are frequently used to assess prevalence, correlates and health benefits of physical activity. However, nonsampling errors, such as question order effects, in surveys may lead to imprecision in self reported physical activity. This study examined the impact of modified question order in a commonly used physical activity questionnaire on the prevalence of sufficient physical activity. Data were obtained from a telephone survey of adults living in Queensland, Australia. A total of 1243 adults participated in the computer-assisted telephone interview (CATI) survey conducted in July 2008 which included the Active Australia Questionnaire (AAQ) presented in traditional or modified order. Binary logistic regression analyses was used to examine relationships between question order and physical activity outcomes. Significant relationships were found between question order and sufficient activity, recreational walking, moderate activity, vigorous activity, and total activity. Respondents who received the AAQ in modified order were more likely to be categorized as sufficiently active (OR = 1.28, 95% CI 1.01-1.60). This study highlights the importance of question order on estimates of self reported physical activity. This study has shown that changes in question order can lead to an increase in the proportion of participants classified as sufficiently active.

Dissociating motivation from reward in human striatal activity.

Miller, Eric M; Shankar, Maya U; Knutson, Brian; McClure, Samuel M

2014-05-01

Neural activity in the striatum has consistently been shown to scale with the value of anticipated rewards. As a result, it is common across a number of neuroscientific subdiscliplines to associate activation in the striatum with anticipation of a rewarding outcome or a positive emotional state. However, most studies have failed to dissociate expected value from the motivation associated with seeking a reward. Although motivation generally scales positively with increases in potential reward, there are circumstances in which this linkage does not apply. The current study dissociates value-related activation from that induced by motivation alone by employing a task in which motivation increased as anticipated reward decreased. This design reverses the typical relationship between motivation and reward, allowing us to differentially investigate fMRI BOLD responses that scale with each. We report that activity scaled differently with value and motivation across the striatum. Specifically, responses in the caudate and putamen increased with motivation, whereas nucleus accumbens activity increased with expected reward. Consistent with this, self-report ratings indicated a positive association between caudate and putamen activity and arousal, whereas activity in the nucleus accumbens was more associated with liking. We conclude that there exist regional limits on inferring reward expectation from striatal activation.

Fluorescence-activated cell sorting (FACS) is an essential tool for studies requiring isolation of distinct intestinal epithelial cell populations. Inconsistent or lack of reporting of the critical parameters associated with FACS methodologies has complicated interpretation, comparison, and reproduction of important findings. To address this problem a comprehensive multicenter study was designed to develop guidelines that limit experimental and data reporting variability and provide a foundation for accurate comparison of data between studies. Common methodologies and data reporting protocols for tissue dissociation, cell yield, cell viability, FACS, and postsort purity were established. Seven centers tested the standardized methods by FACS-isolating a specific crypt-based epithelial population (EpCAM+/CD44+) from murine small intestine. Genetic biomarkers for stem/progenitor (Lgr5 and Atoh 1) and differentiated cell lineages (lysozyme, mucin2, chromogranin A, and sucrase isomaltase) were interrogated in target and control populations to assess intra- and intercenter variability. Wilcoxon's rank sum test on gene expression levels showed limited intracenter variability between biological replicates. Principal component analysis demonstrated significant intercenter reproducibility among four centers. Analysis of data collected by standardized cell isolation methods and data reporting requirements readily identified methodological problems, indicating that standard reporting parameters facilitate post hoc error identification. These results indicate that the complexity of FACS isolation of target intestinal epithelial populations can be highly reproducible between biological replicates and different institutions by adherence to common cell isolation methods and FACS gating strategies. This study can be considered a foundation for continued method development and a starting point for investigators that are developing cell isolation expertise to study physiology and pathophysiology of the intestinal epithelium.

It is well established that acute administration of adrenocortical hormones enhances the consolidation of memories of emotional experiences and, concurrently, impairs working memory. These different glucocorticoid effects on these two memory functions have generally been considered to be independently regulated processes. Here we report that a glucocorticoid receptor agonist administered into the medial prefrontal cortex (mPFC) of male Sprague-Dawley rats both enhances memory consolidation and impairs working memory. Both memory effects are mediated by activation of a membrane-bound steroid receptor and depend on noradrenergic activity within the mPFC to increase levels of cAMP-dependent protein kinase. These findings provide direct evidence that glucocorticoid effects on both memory consolidation and working memory share a common neural influence within the mPFC. PMID:20810923

Spices have enjoyed a long history and a worldwide application. Of particular interest is the pharmaceutical value of spices in addition to its basic seasoning function in cooking. Concretely, equipped with complex chemical compositions, spices are of significant importance in pharmacologic actions, like antioxidant, antibacterial, antitumor, as well as therapeutical effects in gastrointestinal disorders and cardiovascular disease. Although increasing evidences in support of its distinct role in the medical field has recently reported, little information is available for substantive, thorough and sophisticated researches on its chemical constituents and pharmacological activities, especially mechanism of these actions. Therefore, in popular wave of studies directed at a single spice, this review presents systematic studies on the chemical constituents and pharmacological activities associated with common used spices, together with current typical individual studies on functional mechanism, in order to pave the way for the exploitation and development of new medicines derived from the chemical compounds of spice (such as, piperine, curcumin, geniposide, cinnamaldehyde, cinnamic acid, linalool, estragole, perillaldehyde, syringic acid, crocin).

Activating mutations in the Wnt pathway are a characteristic feature of colorectal cancer (CRC). The R-spondin (RSPO) family is a group of secreted proteins that enhance Wnt signaling and RSPO2 and RSPO3 gene fusions have been reported in CRC. We have previously shown that Wnt pathway blockers exhibit potent combinatorial activity with taxanes to inhibit tumor growth. Here we show that RSPO3 antagonism synergizes with paclitaxel based chemotherapies in patient-derived xenograft models (PDX) with RSPO3 fusions and in tumors with common CRC mutations such as APC, β-catenin, or RNF43. In these latter types of tumors that represent over 90% of CRC, RSPO3 is produced by stromal cells in the tumor microenvironment and the activating mutations appear to sensitize the tumors to Wnt-Rspo synergy. The combination of RSPO3 inhibition and taxane treatment provides an approach to effectively target oncogenic WNT signaling in a significant number of patients with colorectal and other intestinal cancers.

Genomic instability is a hallmark of cancer. The WW domain-containing oxidoreductase (WWOX) is a tumor suppressor spanning the common chromosomal fragile site FRA16D. Here, we report a direct role of WWOX in DNA damage response (DDR) and DNA repair. We show that Wwox deficiency results in reduced activation of the ataxia telangiectasia-mutated (ATM) checkpoint kinase, inefficient induction and maintenance of γ-H2AX foci, and impaired DNA repair. Mechanistically, we show that, upon DNA damage, WWOX accumulates in the cell nucleus, where it interacts with ATM and enhances its activation. Nuclear accumulation of WWOX is regulated by its K63-linked ubiquitination at lysine residue 274, which is mediated by the E3 ubiquitin ligase ITCH. These findings identify a novel role for the tumor suppressor WWOX and show that loss of WWOX expression may drive genomic instability and provide an advantage for clonal expansion of neoplastic cells.

To analyze factors associated with the prevalence of the medical diagnosis of vocal fold pathologies in teachers. A census-based epidemiological, cross-sectional study was conducted with 4,495 public primary and secondary school teachers in the city of Salvador, Northeastern Brazil, between March and April 2006. The dependent variable was the self-reported medical diagnosis of vocal fold pathologies and the independent variables were sociodemographic characteristics; professional activity; work organization/interpersonal relationships; physical work environment characteristics; frequency of common mental disorders, measured by the Self-Reporting Questionnaire-20 (SRQ-20 >7); and general health conditions. Descriptive statistical, bivariate and multiple logistic regression analysis techniques were used. The prevalence of self-reported medical diagnosis of vocal fold pathologies was 18.9%. In the logistic regression analysis, the variables that remained associated with this medical diagnosis were as follows: being female, having worked as a teacher for more than seven years, excessive voice use, reporting more than five unfavorable physical work environment characteristics and presence of common mental disorders. The presence of self-reported vocal fold pathologies was associated with factors that point out the need of actions that promote teachers' vocal health and changes in their work structure and organization.

Patient empowerment reflects the ability of patients to positively influence their health and health behavior such as physical activity. While interactive Web-based interventions are increasingly used in various chronic disease settings to enhance empowerment and physical activity, such interventions are still uncommon for cancer survivors. The objective of this study was to systematically review the literature regarding interactive Web-based interventions. We focused on interventions aimed at increasing patient empowerment and physical activity for various chronic conditions, and explored their possible relevance for cancer survivors. Searches were performed in PubMed, Embase, and Scopus to identify peer-reviewed papers reporting on randomized controlled trials that studied the effects of Web-based interventions. These interventions were developed for adults with diabetes, cardiovascular disease, chronic obstructive pulmonary disease, heart failure, or cancer. Intervention characteristics, effects on patient empowerment and physical activity, information on barriers to and facilitators of intervention use, users' experiences, and methodological quality were assessed. Results were summarized in a qualitative way. We used the recommendations of the Institute of Medicine (IOM) regarding cancer survivorship care to explore the relevance of the interventions for cancer survivors. We included 19 papers reporting on trials with 18 unique studies. Significant, positive effects on patient empowerment were reported by 4 studies and 2 studies reported positive effects on physical activity. The remaining studies yielded mixed results or no significant group differences in these outcomes (ie, no change or improvement for all groups). Although the content, duration, and frequency of interventions varied considerably across studies, commonly used elements included education, self-monitoring, feedback/tailored information, self-management training, personal exercise program, and communication (eg, chat, email) with either health care providers or patients. Limited information was found on barriers, facilitators, and users' experiences. Methodological quality varied, with 13 studies being of moderate quality. The reported Web-based intervention elements appeared to be highly relevant to address the specific needs of cancer survivors as indicated by the IOM. We identified 7 common elements of interactive, Web-based interventions in chronic disease settings that could possibly be translated into eHealth recommendations for cancer survivors. While further work is needed to determine optimal intervention characteristics, the work performed in other chronic disease settings provides a basis for the design of an interactive eHealth approach to improve patient empowerment and physical activity in cancer survivors. This may subsequently improve their health status and quality of life and reduce their need for supportive care.

Background The herbicides glyphosate (Gly) and imazamox (Imx) inhibit the biosynthesis of aromatic and branched-chain amino acids, respectively. Although these herbicides inhibit different pathways, they have been reported to show several common physiological effects in their modes of action, such as increasing free amino acid contents and decreasing soluble protein contents. To investigate proteolytic activities upon treatment with Gly and Imx, pea plants grown in hydroponic culture were treated with Imx or Gly, and the proteolytic profile of the roots was evaluated through fluorogenic kinetic assays and activity-based protein profiling. Results Several common changes in proteolytic activity were detected following Gly and Imx treatment. Both herbicides induced the ubiquitin-26 S proteasome system and papain-like cysteine proteases. In contrast, the activities of vacuolar processing enzymes, cysteine proteases and metacaspase 9 were reduced following treatment with both herbicides. Moreover, the activities of several putative serine protease were similarly increased or decreased following treatment with both herbicides. In contrast, an increase in YVADase activity was observed under Imx treatment versus a decrease under Gly treatment. Conclusion These results suggest that several proteolytic pathways are responsible for protein degradation upon herbicide treatment, although the specific role of each proteolytic activity remains to be determined.

Antimicrobial activity was examined in the gorgonian Leptogorgia virgulata (common seawhip) from South Carolina waters. Extraction and assay protocols were developed to identify antimicrobial activity in crude extracts of L. virgulata. Detection was determined by liquid growth inhibition assays using Escherichia coli BL21, Vibrio harveyii, Micrococcus luteus, and a Bacillus sp. isolate. This represents the first report of antimicrobial activity in L. virgulata, a temperate/sub-tropical coral of the western Atlantic Ocean. Results from growth inhibition assays guided a fractionation scheme to identify active compounds. Reverse-phase HPLC, HPLC-mass spectrometry, and 1H and 13C NMR spectroscopy were used to isolate, purify, and characterize metabolites in antimicrobial fractions of L. virgulata. Corroborative HPLC-MS/NMR evidence validated the presence of homarine and a homarine analog, well-known emetic metabolites previously isolated from L. virgulata, in coral extracts. In subsequent assays, partially-purified L. virgulata fractions collected from HPLC-MS fractionation were shown to contain antimicrobial activity using M. luteus and V. harveyii. This study provides evidence that homarine is an active constituent of the innate immune system in L. virgulata. We speculate it may act synergistically with cofactors and/or congeners in this octocoral to mount a response to microbial invasion and disease.

This study assessed the interest of alternative high school staff in intervention research on students' eating and physical activity habits and the feasibility of conducting such research in alternative school settings. A two-phase descriptive design incorporated both quantitative and qualitative methods. In fall/winter 2001-2002, alternative high school administrators in Minnesota were surveyed (response rate = 83%; n = 130/157). During summer 2002, one-on-one, semistructured interviews were conducted with key school personnel (n = 15) from urban and suburban schools. Findings indicated few schools had been invited to participate in research on nutrition (11%) and physical activity (7%). However, more than 80% of administrators reported interest in their students participating in such research. Most schools offered health and PE classes and had access to indoor gym facilities and outdoor play areas. While most schools offered a school lunch program, participation was low, cold lunches were common, and food often was unappealing. Beverage and snack vending machines were common. Overall, the physical environment of most alternative schools did not support physical activity and healthy eating as normative behavior. Interest in interventions on physical inactivity, unhealthy dietary practices, and other priority health-risk behavior common in students attending alternative schools was high among teachers and administrators. Results suggest research in alternative high schools is feasible and successful implementation and evaluation of programs possible.

Dysmenorrhea is one of the most common and important health problems, especially among young girls. It results in absence from school and work. It has some negative effects on the daily activities of patients. Because of cultural problems, patients ordinarily do not seek help from others in this situation. Identification of abnormal menstrual patterns during adolescence may permit early prevention of potential health concerns in adulthood. The aim of this study was to determine the prevalence, severity, and impact of dysmenorrhea in secondary-school students and its association with school absenteeism in Arar city. A cross-sectional descriptive study was conducted in four secondary schools for girls in Arar city on 344 secondary school students during the academic year 2015-2016. A self-administered questionnaire was distributed to all participants; questions were related to menstruation, elucidating variations in menstrual patterns, history of dysmenorrheal, and absenteeism from school. All adolescent school girls completed the questionnaire (n=344). The prevalence of dysmenorrhea was 74.4% (n=256) (mild=21.1%, moderate=41.4%, and severe=37.5%). Family history of dysmenorrhea was reported among 65.6% and fatigue was the most commonly associated symptom (79.7%) among dysmenorrheic girls. Limitation of activities was reported by the majority of participants with dysmenorrhea. Activities affected by dysmenorrhea included homework (78.9%), daily activities (75%), class concentration (71.9%), school attendance (59.4%), and academic performance (52.3%); about 50.8% reported social withdrawal due to dysmenorrhea. Eighteen percent consulted a school physician and 57.8% received herbal drinks to alleviate symptoms of dysmenorrhea. Dysmenorrhea is highly prevalent among adolescent secondary-school girls and is associated with school absenteeism and limitations on social and academic activities. Given that most adolescents do not seek medical advice for dysmenorrhea, healthcare providers should screen routinely for dysmenorrhea and offer treatment. As dysmenorrhea reportedly affects school performance, school administrators may have a vested interest in providing health education on this topic to their students. Health education has to be supplemented by availability of other services such as consultation with school nurse and school physician and availability of drugs that alleviate pain.

Match and training injuries in rugby league: a review of published studies.

Rugby league is an international collision sport played by junior, amateur, semiprofessional and professional players. The game requires participants to be involved in physically demanding activities such as running, tackling, passing and sprinting, and musculoskeletal injuries are common. A review of injuries in junior and senior rugby league players published in Sports Medicine in 2004 reported that injuries to the head and neck and muscular injuries were common in senior rugby league players, while fractures and injuries to the knee were common in junior players. This current review updates the descriptive data on rugby league epidemiology and adds information for semiprofessional, amateur and junior levels of participation in both match and training environments using studies identified through searches of PubMed, CINHAL, Ovid, MEDLINE, SCOPUS and SportDiscus databases. This review also discusses the issues surrounding the definitions of injury exposure, injury rate, injury severity and classification of injury site and type for rugby league injuries. Studies on the incidence of injuries in rugby league have suffered from inconsistencies in the injury definitions utilized. Some studies on rugby league injuries have utilized a criterion of a missed matchas an injury definition, total injury incidences or a combination of both time-loss and non-time-loss injuries, while other studies have incorporated a medical treatment injury definition. Efforts to establish a standard definition for rugby league injuries have been difficult, especially as some researchers were not in favour of a definition that was all-encompassing and enabled non-time-loss injuries to be recorded. A definition of rugby league injury has been suggested based on agreement by a group of international researchers. The majority of injuries occur in the match environment, with rates typically increasing as the playing level increases. However, professional level injury rates were reportedly less than semiprofessional participation. Only a few studies have reported training injuries in rugby league, where injury rates were reported to be less than match injuries. Approximately 16-30% of all rugby league injuries have been reported as severe, which places demands upon other team members and, if the player returns to playing too early, places them at an increased risk of further injuries. Early research in rugby league identified that ligament and joint injuries were the common injuries, occurring primarily to the knee. More recently, studies have shown a change in anatomical injury sites at all levels of participation. Although the lower limb was the frequent injury region reported previously, the shoulder has now been reported to be the most common injury site. Changes in injury site and type could be used to prompt further research and development of injury reduction programmes to readdress the issue of injuries that occur as a result of participation in rugby league activities. Further research is warranted at all participation levels of rugby league in both the match and training environments to confirm the strongest risk factors for injury.

Health and wellness programming in faith-based organizations: a description of a nationwide sample.

Most of the U.S. population is affiliated with faith-based organizations (FBOs) and regularly attends services. Health and wellness activities (HWA) delivered through FBOs have great potential for reach, but the number of FBOs offering health programs and the characteristics of these programs are currently unknown. The purpose of this study was to better understand rates, characteristics, and factors influencing faith-based HWA across the United States. Faith leaders (N = 844) completed an online survey assessing faith leader demographics and health, FBO demographics (e.g., denomination, size, location, diversity), and details of HWA within their FBO. Respondents were primarily White (93%), male (72%), middle-aged (53.2 ± 12.1 years), and affiliated with Methodist (42.5%) or Lutheran (20.2%) denominations. Although most faith leaders report meeting physical activity recommendations (56.5%), most were overweight/obese (77.4%), did not meet fruit and vegetable recommendations (65.9%), and had been diagnosed with 1.25 ± 1.36 chronic diseases. Respondents reported offering 4.8 ± 3 HWA within their FBO over the past 12 months. Most common HWA included clubs/teams related to physical activity (54.8%), individual-level health counseling (54%), and providing health/wellness pamphlets. Leaders cited a lack of lay leadership (48.1%) and financial resources for staff time (47.8%) as the most common barriers to HWA. An increase in interest/awareness in health topics from FBO members was the most common facilitator for HWA (66.5%). Although faith-based HWA are prevalent nationally, types of HWA and the factors influencing HWA are dependent on FBO characteristics. Future faith-based interventions should consider existing capabilities and moderating factors for HWA.

To examine the experiences of volunteers of the Foundation for International Education in Neurological Surgery. A qualitative analysis of >150 volunteer reports from 2004-2013 was performed using grounded theory. Various themes were explored based on their occurrence in the reports. Volunteer reports of extended trips appeared to peak in 2009, with a heavy emphasis on activity in Africa. Prominent themes in the reports included volunteer contributions, successful strategies, challenges, and future directions. Volunteers demonstrated wide-ranging contributions. Successful strategies included continuity and collaboration with other organizations. Challenges were overwhelmingly related to equipment or infrastructure. Common suggestions for future directions included institutional collaboration and subspecialty development. Copyright © 2014 Elsevier Inc. All rights reserved.

European legislation requires reporting from Member States on acute poisoning incidents involving pesticides. However, standard rules for data collection and reporting have not yet been set out. The new categorization system presented in this paper is aimed at enabling Member States to gather comparable data and provide standard reporting on pesticide poisoning exposures. European Regulations providing separate official categorization of biocidal and plant protection pesticides, were used as a basis to build up a unified pesticide categorization and coding system. Data on selected pesticide exposures collected by Poison Control Centres in six EU countries were reviewed, categorized and reported according to the proposed system. The resulting pesticide categorization system has two dimensions. The first part identifies the main category of use, i.e. biocide/plant protection pesticide/unknown, and the secondary category of use, e.g. Rodenticides, Insecticides and acaricides. The second part of the system is organized into two levels: level one identifies chemical grouping, e.g. Coumarins, Pyrethrins/pyrethroids, while level two identifies the active compound by using its Chemical Abstract Service Registry Number. The system was used to provide a unified categorization to compare exposures to plant protection and biocidal Rodenticides and Pyrethrins/pyrethroids Insecticides and acaricides identified by six EU member states. The developed pesticide categorization system was successfully applied to data extracted from different databases and was able to make the required information comparable. The data reported filling in common templates containing a pre-ordinate list of active compounds categorized according the proposed system, highlighted different capabilities in data collection and recording, showing that some of the collaborating centres were not able to distinguish between main categories of pesticide products or provide information on active compounds. The results indicate that a special effort should be dedicated to support detailed data recording at national level. Providing common tools to systematically report to the EU Commission hazardous exposures to pesticides, as well as to other selected categories of products, could allow for data comparability between Member States and greatly improve post marketing surveillance and alerting systems in Europe.

2009-11-01

The primary aim of this study was to examine the association between physical activity and quality of life (QoL) in cancer patients receiving palliative care. Fifty advanced cancer patients aged 18 years or older with clinician-estimated life expectancy of 3-12 months and Palliative Performance Status Scale scores greater than 30% were recruited from an outpatient palliative care clinic and palliative home care. Participants completed a cross-sectional survey by means of face-to-face interview assessing self-reported QoL (McGill Quality of Life Questionnaire [MQOL]), self-reported physical function (Late-Life Function and Disability Instrument), symptoms (Edmonton Symptom Assessment System), and physical activity behavior. Seventy-six percent (38 of 50) of the participants were deceased at the time of data analysis, with a median survival of 104 days from time of survey to time of death. Walking was the most common reported physical activity. Analyses of variance indicated that participants who reported walking more than 30 minutes per day also reported higher existential subscores (+/-0.8 [95% CI, 0.0-1.5]; P=0.045), support subscores (+/-0.7 [95% CI, 0.1-1.4]; P=0.027), and total scores (+/-0.5 [95% CI, 0.0-0.9]; P=0.046) on the MQOL. There were no significant differences for self-reported physical function or symptoms. Our findings show a significant positive association between physical activity and QoL scores in this sample of patients with advanced cancer. A pilot intervention trial testing the causal effects of physical activity on QoL in cancer patients receiving palliative care is warranted.

Screen-based media use by children and adolescents has increased in recent years but the consequences of their use are not well understood. The objective of this study was to provide a comprehensive examination of the relationship between screen-based activities and a selection of single and multiple self-reported somatic symptoms in a large sample of 10-12 year old children. We use data from the population-based 2011 Youth in Iceland school survey (N=10,829, response rate: 84.5%, boys: 49.9%) that is conducted triennially in 5th-7th grades in all secondary schools in Iceland. Self-reported measures of common screen-based activities were hypothesized to predict the odds of dizziness, tremors, headaches, stomach aches, and multiple symptoms. In general the reported prevalence of symptoms increased with greater number of hours reported on screen based activity for boys and girls. This held for all individual screen activities as well as the cumulative measure of daily minutes spent on screen-based media and prevalence of one or more somatic symptoms. This study confirms previous findings and puts forth additional information concerning the relationship between the prevalence of electronic screen use and somatic symptoms in 10-12 year old children.

2009-01-01

Obesity rates are rising in the United States, especially among low-income and racial/ethnic minority individuals. Exploring motivators and barriers relative to engaging in physical activity is imperative. The purpose of this study was to identify motivators and barriers relative to engagement in physical activity as reported by culturally diverse low-income adolescents and adults. A total of 91 adolescent (11 to 15 years of age) and adult (18 years of age or older) participants who self-identified as African American, Hispanic, or non-Hispanic White engaged in age group-, race/ethnicity-, and gender-concordant focus groups. Qualitative data analysis indicated that the motivators and barriers most commonly identified among the adolescent and adult focus groups were: social influence; time and priorities; physical environment; fun and enjoyment; inherently physical activities; weight concerns; fatigue, physical discomfort and current fitness level; and immediate positive feelings. Findings were generally similar across age group, gender and race/ethnicity. Age group-specific, gender-specific and race/ethnicity-specific motivators and barriers were related to how commonly the motivators and barriers were identified among each group. Implications for increasing physical activity among low-income culturally diverse adolescents and adults are discussed.

Classification of Sporting Activities Using Smartphone Accelerometers

PubMed Central

Mitchell, Edmond; Monaghan, David; O'Connor, Noel E.

2013-01-01

In this paper we present a framework that allows for the automatic identification of sporting activities using commonly available smartphones. We extract discriminative informational features from smartphone accelerometers using the Discrete Wavelet Transform (DWT). Despite the poor quality of their accelerometers, smartphones were used as capture devices due to their prevalence in today's society. Successful classification on this basis potentially makes the technology accessible to both elite and non-elite athletes. Extracted features are used to train different categories of classifiers. No one classifier family has a reportable direct advantage in activity classification problems to date; thus we examine classifiers from each of the most widely used classifier families. We investigate three classification approaches; a commonly used SVM-based approach, an optimized classification model and a fusion of classifiers. We also investigate the effect of changing several of the DWT input parameters, including mother wavelets, window lengths and DWT decomposition levels. During the course of this work we created a challenging sports activity analysis dataset, comprised of soccer and field-hockey activities. The average maximum F-measure accuracy of 87% was achieved using a fusion of classifiers, which was 6% better than a single classifier model and 23% better than a standard SVM approach.

This study examined associations between reports of receiving education on topics commonly included in sex education (e.g., abstinence only, comprehensive) prior to age 18 years and contraceptive use at the last sex among heterosexually active, 15- to 20-year-old males in the United States. Cross-sectional data from 539 males participating in the 2011-2013 National Survey of Family Growth were analyzed. Bivariate and multinomial logistic regression analyses adjusting for confounding estimated associations between receipt of seven sex education topics (e.g., information on HIV/AIDS, how to say no to sex) and contraceptive use at the last sex (i.e., dual barrier and female-controlled effective methods, female-controlled effective method only, barrier method only, and no method). Nearly, all participants (99%) reported receiving sex education on at least one topic. Education on sexually transmitted diseases (94.7%) and HIV/AIDS (92.0%) were the most commonly reported topics received; education on where to get birth control was the least common (41.6%). Instruction about birth control methods (adjusted odds ratio [AOR] = 3.01; 95% confidence interval [CI] = 1.32-6.87) and how to say no to sex (AOR = 3.39; CI = 1.33-8.64) were positively associated with dual contraception compared to no use. For each additional sex education topic respondents were exposed to, their odds of using dual methods compared to no method was 47% greater (AOR = 1.47; CI = 1.16-1.86). Exposure to a larger number of sex education topics is associated with young men's report of dual contraception use at the last sex. Comprehensive sex education, focusing on a range of topics, may be most effective at promoting safer sex among adolescent males. Copyright © 2016 Society for Adolescent Health and Medicine.

Understanding variations in physical activity patterns is important for planning health interventions. This study describes age-related change in physical activity in 903 rural Hispanic and non-Hispanic white (NHW) adults age 55-80. The Physical Activity History assessed 13 categories of productive and recreational activity during the past year with up to four assessments per participant from 1987 to 1998. The most common activities were walking and home maintenance/gardening. Productive and recreational physical activity levels were lower in women than men (P < 0.0001), and within each gender group Hispanics had lower levels of both activity types than NHW (P values less than 0.05). In men, productive activity steadily declined with age in NHW and Hispanics. Recreational activity increased slightly until age 63, then decreased after age 70. In women, productive activity initially stayed stable then decreased in NHW after age 63, and in Hispanics it decreased at younger ages before stabilizing after age 70. Recreational activity levels decreased steadily with age in all women, with a steeper rate of decline in NHW than Hispanics. In both ethnic groups, activity levels were lower in diabetics than nondiabetics, except for recreational activity in women where levels did not differ by diabetes status. The most common activities were similar to other studies of older adults, both recreational and productive activities contributed to total activity, and physical activity decreased in all gender-ethnic subgroups with age. Hispanic women reported the lowest activity levels. Interventions to maintain or increase recreational activity may need to target women at an earlier age than men.

The emergence of a multitarget design approach in the development of new potential anti-Alzheimer's disease agents has resulted in the discovery of many multifunctional compounds focusing on various targets. Among them the largest group comprises inhibitors of both cholinesterases, with additional anti-β-amyloid aggregation activity. This review describes recent advances in this research area and presents the most interesting compounds reported over a 2-year span (2015-2016). The majority of hybrids possess heterodimeric structures obtained by linking structurally active fragments interacting with different targets. Multipotent cholinesterase inhibitors with β-amyloid antiaggregating activity may additionally possess antioxidative, neuroprotective or metal-chelating properties or less common features such as anti-β-secretase or τ-antiaggregation activity.

2014-01-01

Nowadays, in Italy the reports of mnusculoskeletal diseases increase as confirmed in the last INAIL (national insurance for occupational diseases and injuries) annual report. The Emilia-Ronmagna is one of the region with the highest number of reports: 15.9% of the total in 2012. The decree no. 81/08 has partially simplified the medico-legal activities related to musculoskeletal diseases; however, the medico-legal physicians have still to deal with some issues such as risk assessment quality, economic crisis, and specific work environments (e.g. agriculture and many handicraft activities). Tire risk factors of musculoskeletal diseases and their assessments are quite well studied. The latency period of these diseases needs to be investigated, since it could be a relevant aspect for legal medical judgment, insurance protection and prevention. Based on literature data and INAIL experience, authors propose some considerations useful for a scientific debate.

Gc protein-derived macrophage-activating factor (GcMAF) immunotherapy has been steadily advancing over the last two decades. Oral colostrum macrophage-activating factor (MAF) produced from bovine colostrum has shown high macrophage phagocytic activity. GcMAF-based immunotherapy has a wide application for use in treating many diseases via macrophage activation or for use as supportive therapy. Three case studies demonstrate that oral colostrum MAF can be used for serious infection and chronic fatigue syndrome (CFS) without adverse effects. We demonstrate that colostrum MAF shows promising clinical results in patients with infectious diseases and for symptoms of fatigue, which is common in many chronic diseases.

LaDuke, Casey; Barr, William; Brodale, Donald L; Rabin, Laura A

2018-01-01

This study investigated professional practice and common test use among clinical neuropsychologists engaging in forensic assessment.  Doctorate-level psychologists active in the practice of neuropsychology and on the INS and NAN membership listings (n = 502) were surveyed about their demographics, professional practice, and common test use. Participants who reported engaging in forensic practice (n = 255) were further surveyed about their forensic practice. Forensic participants were more likely to be male and Caucasian, and reported higher ages, more years of professional experience, and a higher prevalence of board certification. While characteristics of their professional and forensic practice varied, forensic participants reported spending most of their professional time conducting neuropsychological assessments with adult clients in a private or group practice setting, focusing on civil referrals and civil legal questions involving older adult issues, developmental issues, head injury, and psychiatric issues. Common test use across neuropsychological assessment domains is presented for board-certified forensic participants (n = 77). An examination of these results reveals that the current pattern of test use is similar to the results of a more general survey of neuropsychological test use.  The findings provide insight into the practice of forensic neuropsychological assessment, and further establish the admissibility of neuropsychological evidence in the United States legal system. Results will be useful for clinical neuropsychologists, field leaders, and legal professionals hoping to gain insight into the role of clinical neuropsychology in civil and criminal legal decision-making.

We synthesized the results of 7 National Park Service pilot interventions designed to increase awareness of the health benefits from participation in recreation at national parks and to increase physical activity by park visitors. A content analysis was conducted of the final evaluation reports of the 7 participating parks. Pooled data were also analyzed from a standardized trail-intercept survey administered in 3 parks. The theme of new and diverse partnerships was the most common benefit reported across the 7 sites. The 2 parks that focused on youth showed evidence of an increase in awareness of the benefits of physical activity. Many of the other sites found high levels of awareness at baseline (approaching 90%), suggesting little room for improvement. Five of the 7 projects showed evidence of an increase in physical activity that was associated with the intervention activities. Multivariate analyses suggested that the media exposure contributed to a small but significant increase in awareness of the importance of physical activity (6%) and number of active visits (7%). Enhancements and replication of these programs represents a promising opportunity for improving partnerships between public health and recreation to increase physical activity.

Sensitization to allergens in atopic dermatitis patients is a risk factor for developing asthma and allergic rhinitis in the future,as well as an aggravating factor in the course of the disease. Recent studies have attributed the activity of the proteases of some antigens to cause a grater defect in the epithelial barrier and a more severe disease. To know the sensitization to allergens pattern in children with atopic dermatitis attended at Allergology Service of University Hospital of UANL, Mexico, and to know if these children have higher sensitization to antigens with proteolytic activity. A retrospective study was done reviewing the skin prick test reports done in our service to children ranging from 5 months to 16 years old, diagnosed with atopic dermatitis during a period of 2 years, from January 2012 to January 2014. The frequency of sensitization to aeroallergens and food were analyzed as well as the weal size (≥6mm) on the skin in response to each particular allergen in the case of food skin prick test. Reports of skin tests of 66 children, 30 boys and 36 girls, were included; 37 of children were sensitized to more than one allergen,18/66 had asthma and/or allergic rhinitis, 40/66 60% skin prick tests were positive to high activity protease aeroallergens (Dermatophagoides pteronyssinus/Dermatophagoides farinae). Regarding food, sensitization was seen in 38 children; fruits and vegetables were the two most common foods. Only seven children had skin prick weal bigger than 6 mm, mainly to egg, fish and cow's milk. Children with atopic dermatitis are often sensitized to high protease activity aeroallergens, polysensitization is very common and the association with airway allergy is seen early in life. Sensitization to food is also common in these patients, but only a small percentage showed a response large enough to be associated with disease severity.

Cre-mediated recombination in pituitary somatotropes

Nasonkin, Igor O.; Potok, Mary Anne; Camper, Sally A.

2009-01-01

We report a transgenic line with highly penetrant cre recombinase activity in the somatotrope cells of the anterior pituitary gland. Expression of the cre transgene is under the control of the locus control region of the human growth hormone gene cluster and the rat growth hormone promoter. Cre recombinase activity was assessed with two different lacZ reporter genes that require excision of a floxed stop sequence for expression: a chick β-actin promoter with the CMV enhancer transgene and a ROSA26 knock-in. Cre activity is detectable in the developing pituitary after initiation of Gh transcription and persists through adulthood with high penetrance in Gh expressing cells and lower penetrance in lactotropes, a cell type that shares a common origin with somatotropes. This Gh-cre transgenic line is suitable for efficient, cell-specific deletion of floxed regions of genomic DNA in differentiated somatotropes and a subset of lactotrope cells of the anterior pituitary gland.

Uncaria rhynchophylla is commonly recognized as a traditional treatment for dizziness, cerebrovascular diseases, and nervous disorders in China. Previously, the neuro-protective activities of the alkaloids from U. rhynchophylla were intensively reported. In current work, three new indole alkaloids (1-3), identified as geissoschizic acid (1), geissoschizic acid N 4 -oxide (2), and 3β-sitsirikine N 4 -oxide (3), as well as 26 known analogues were isolated from U. rhynchophylla. However, in the neural stem cells (NSCs) proliferation assay for all isolated compounds, geissoschizic acid (1), geissoschizic acid N 4 -oxide (2), isocorynoxeine (6), isorhynchophylline (7), (4S)-akuammigine N-oxide (8), and (4S)-rhynchophylline N-oxide (10) showed unexpected inhibitory activities at 10 μM. Unlike previous neuro-protective reports, as a warning or caution, our finding showcased a clue for possible NSCs toxicity and the neural lesions risk of U. rhynchophylla, while the structure-activity relationships of the isolated compounds were discussed also.

Music is a powerful means for communicating emotions among individuals. Here we reveal that this continuous stream of affective information is commonly represented in the brains of different listeners and that particular musical attributes mediate this link. We examined participants' brain responses to two naturalistic musical pieces using functional Magnetic Resonance imaging (fMRI). Following scanning, as participants listened to the musical pieces for a second time, they continuously indicated their emotional experience on scales of valence and arousal. These continuous reports were used along with a detailed annotation of the musical features, to predict a novel index of Dynamic Common Activation (DCA) derived from ten large-scale data-driven functional networks. We found an association between the unfolding music-induced emotionality and the DCA modulation within a vast network of limbic regions. The limbic-DCA modulation further corresponded with continuous changes in two temporal musical features: beat-strength and tempo. Remarkably, this "collective limbic sensitivity" to temporal features was found to mediate the link between limbic-DCA and the reported emotionality. An additional association with the emotional experience was found in a left fronto-parietal network, but only among a sub-group of participants with a high level of musical experience (>5years). These findings may indicate two processing-levels underlying the unfolding of common music emotionality; (1) a widely shared core-affective process that is confined to a limbic network and mediated by temporal regularities in music and (2) an experience based process that is rooted in a left fronto-parietal network that may involve functioning of the 'mirror-neuron system'.

Hand eczema is common in the nursing profession, and has been reported widely in various parts of the world. The aim of this study was to determine the prevalence and severity of hand eczema among nurses working in a regional hospital in Hong Kong, as well as its psychosocial impact and any possible associated risk factors. The study took the form of a self-report questionnaire survey; 1240 nurses in a regional hospital were asked to participate in the survey by completing the questionnaire and returning it anonymously within 2 weeks. Seven hundred and twenty-four nurses returned the questionnaire (a response rate of 59%). The prevalence of hand eczema among the respondents was 22.1% (160/724). More than 90% had moderate to severe hand eczema. Itchiness and dryness were the most common symptoms. Occupational work, housework, mood, social activities and sleep were particularly affected. Multinomial logistic regressions showed that a personal or family history of atopy and a hand washing frequency of >20 times per day were independent risk factors for hand eczema. Hand eczema is common and severe among Hong Kong nurses. The results of this study suggest that hand eczema is an important problem for nurses and that preventive measures should be emphasized. © 2011 John Wiley & Sons A/S.

A depressed autophagy has previously been reported in cystic fibrosis patients with the common F508del-CFTR mutation. This report describes the synthesis and preliminary biological characterization of a novel series of autophagy activators involving fatty acid cysteamine conjugates. These molecular entities were synthesized by first covalently linking cysteamine to docosahexaenoic acid. The resulting conjugate 1 synergistically activated autophagy in primary homozygous F508del-CFTR human bronchial epithelial (hBE) cells at submicromolar concentrations. When conjugate 1 was used in combination with the corrector lumacaftor and the potentiator ivacaftor, it showed an additive effect, as measured by the increase in the chloride current in a functional assay. In order to obtain a more stable form for oral dosing, the sulfhydryl group in conjugate 1 was converted into a functionalized disulfide moiety. The resulting conjugate 5 is orally bioavailable in the mouse, rat, and dog and allows a sustained delivery of the biologically active conjugate 1.

Yoga practice is reported to lead to improvements in quality of life, psychological functioning, and symptom indices in cancer survivors. Importantly, meditative states experienced within yoga practice are correlated to neurophysiological systems that moderate both focus of attention and affective valence. The current study used a mixed methods approach based in neurophenomenology to investigate associations between attention, affect, and cardiac activity during a single yoga session for female cancer survivors. Yoga practice was associated with a linear increase in associative attention and positive affective valence, while shifts in cardiac activity were related to the intensity of each yoga sequence. Changes in attention and affect were predicted by concurrently assessed cardiac activity. Awareness of breathing, physical movement, and increased relaxation were reported by participants as potential mechanisms for yoga's salutary effects. While yoga practice shares commonalities with exercise and relaxation training, yoga may serve primarily as a promising meditative attention-affect regulation training methodology.

Focused attention, open monitoring and automatic self-transcending: Categories to organize meditations from Vedic, Buddhist and Chinese traditions.

PubMed

Travis, Fred; Shear, Jonathan

2010-12-01

This paper proposes a third meditation-category--automatic self-transcending--to extend the dichotomy of focused attention and open monitoring proposed by Lutz. Automatic self-transcending includes techniques designed to transcend their own activity. This contrasts with focused attention, which keeps attention focused on an object; and open monitoring, which keeps attention involved in the monitoring process. Each category was assigned EEG bands, based on reported brain patterns during mental tasks, and meditations were categorized based on their reported EEG. Focused attention, characterized by beta/gamma activity, included meditations from Tibetan Buddhist, Buddhist, and Chinese traditions. Open monitoring, characterized by theta activity, included meditations from Buddhist, Chinese, and Vedic traditions. Automatic self-transcending, characterized by alpha1 activity, included meditations from Vedic and Chinese traditions. Between categories, the included meditations differed in focus, subject/object relation, and procedures. These findings shed light on the common mistake of averaging meditations together to determine mechanisms or clinical effects. Copyright © 2010 Elsevier Inc. All rights reserved.

Bullying is a widespread problem for school-aged children and adolescents. Interventions to reduce bullying are not well disseminated. Extracurricular involvement is, however, common. This study aims to examine the relationship between parent-reported participation in extracurricular activities and bullying perpetration. Using the 2011 National Survey of Children's Health, 62,215 interviews with parents of children 6 to 17 were analyzed. Extracurricular categories of sports only, sports + nonsport, nonsport only, and no activities were based on parental response to questions regarding sport teams/lessons, clubs, and organizations. Bullying was derived from report of the child "bullying or being cruel/mean to others." Weighted bivariate analyses, logistic regression, and sex/race/ethnicity/age stratified analyses were conducted. Eighty percent of children participated in extracurricular activities: 8% sports, 48% sports + nonsports, and 24% nonsports. Bullying perpetration was reported in 15% of the sample. Compared with those not participating in extracurricular activities, the odds of bullying were significantly lower for children who participated in sports + nonsports (Adjusted odds ratio (AOR) 0.67, 95% confidence interval [CI] 0.57-0.79) and nonsport only (AOR 0.82, 95% CI 0.70-0.97). Stratified analyses showed attenuated effects of extracurricular activities for boys and for Hispanics. Children who participate in a variety of extracurricular activities exhibit the least frequent bullying perpetration. © 2015, American School Health Association.

Desbuquois dysplasia (DBQD) is a rare skeletal dysplasia characterized by severe short stature, laxity, dislocation of multiple joints and developmental delay. DBQD is clinically heterogeneous. Distinct radiographic hand abnormalities such as the presence of extra-ossification distal to the second metacarpal or normal hand has led to its classification into types 1 and 2. Furthermore, the third type of DBQD, Kim type has been reported which is characterized by short metacarpals and elongated phalanges. However, DBQD Kim type has been exclusively reported in Japanese and Korean and its clinical characteristics remain to be delineated. Mutations in the calcium-activated nucleotidase 1 (CANT1) gene have been reported in all three types of DBQD. Previously reported patients with DBQD Kim type had a common mutation c.676G>A (p.Val226Met), which had a common founder between Japanese and Korean. Here, we report 3 Indian patients with DBQD, Kim type from 2 families which were unrelated to each other. We identified a novel mutation of CANT1, c.467C>T (p.Ser156Phe), in all the patients in the homozygous form. Our results show that DBQD Kim type is not exclusive to East Asians and also report a novel mutation from the Indian subcontinent. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Reflecting on non-reflective action: An exploratory think-aloud study of self-report habit measures

PubMed Central

Gardner, Benjamin; Tang, Vinca

2014-01-01

Objectives Within health psychology, habit – the tendency to enact action automatically as a learned response to contextual cues – is most commonly quantified using the ‘Self-Report Habit Index’, which assesses behavioural automaticity, or measures combining self-reported behaviour frequency and context stability. Yet, the use of self-report to capture habit has proven controversial. This study used ‘think-aloud’ methods to investigate problems experienced when completing these two measures. Design Cross-sectional survey with think-aloud study. Methods Twenty student participants narrated their thoughts while completing habit measures applied to four health-related behaviours (active commuting, unhealthy snacking, and one context-free and one context-specific variant of alcohol consumption). Data were coded using thematic analysis procedures. Results Problems were found in 10% of responses. Notable findings included participants lacking confidence in reporting automaticity, struggling to recall behaviour or cues, differing in interpretations of ‘commuting’, and misinterpreting items. Conclusions While most responses were unproblematic, and further work is needed to investigate habit self-reports among larger and more diverse samples, findings nonetheless question the sensitivity of the measures, and the conceptualization of habit underpinning common applications of them. We offer suggestions to minimize these problems. PMID:23869847

Aberrant Muscle Syndrome (AMS) is a rare congenital hand difference that is characterised by unilateral non-progressive muscular hyperplasia. The aetiology of aberrant muscle syndrome is not known, but a recently published case has shown a somatic PIK3CA activating mutation in a patient with AMS. Carpal tunnel syndrome (CTS) in children is rare. The most common causes are the mucopolysaccaridoses but space-occupying lesions have also been reported to cause CTS in children. We report the first case of CTS in a child with AMS successfully treated with open carpal tunnel release and excision of aberrant muscles.

AIM: To investigate factors related to hopelessness in a sample of epileptic patients, including measures of depression and quality of life (QOL). METHODS: Sixty-nine participants were administered the following psychometric instruments: Beck Depression Inventory-II, Beck Hopelessness Scale (BHS), and QOL in Epilepsy (QOLIE)-89. Patients were dichotomized into two categories: those affected by epilepsy with generalized tonic-clonic seizures vs those having epilepsy with partial seizures. RESULTS: The groups differed on the QOLIE Role Limitation/Emotional dimension. Patients with generalized seizures reported more limitations in common social/role activities related to emotional problems than patients with other types of epilepsy (89.57 ± 25.49 vs 72.86 ± 36.38; t63 = -2.16; P < 0.05). All of the respondents reported moderate to severe depression, and 21.7% of patients with generalized seizures and 28.6% of patients with other diagnoses had BHS total scores ≥ 9 indicating a higher suicidal risk. The study did not control for years of the illness. CONCLUSION: Patients with generalized seizures reported more limitations in common social/role activities related to emotional problems compared to patients with other types of seizures. Patients at increased suicide risk as evaluated by the BHS were older than those who had a lower suicidal risk. Future studies are required to further investigate the impact of hopelessness on the outcome of epileptic patients. PMID:25540729

Prefrontal Asymmetry and Parent-Rated Temperament in Infants

PubMed Central

LoBue, Vanessa; Coan, James A.; Thrasher, Cat; DeLoache, Judy S.

2011-01-01

Indicators of temperament appear early in infancy and remain relatively stable over time. Despite a great deal of interest in biological indices of temperament, most studies of infant temperament rely on parental reports or behavioral tasks. Thus, the extent to which commonly used temperament measures relate to potential biological indicators of infant temperament is still relatively unknown. The current experiment examines the relationship between a common parental report measure of temperament – the Infant Behavior Questionnaire – Revised (IBQ-R) – and measures of frontal EEG asymmetry in infants. We examined associations between the subscales of the IBQ-R and frontal EEG asymmetry scores recorded during a combined series of neutral attentional and putatively emotional recording conditions in infants between 7 and 9 months of age. We predicted that approach-related subscales of the IBQ-R (e.g., Approach, Soothability) would be related to greater left prefrontal asymmetry, while withdrawal-related subscales (e.g., Distress to Limitations, Fear, Falling Reactivity, Perceptual Sensitivity) would be related to greater right prefrontal asymmetry. In the mid- and lateral-frontal regions, Approach, Distress to Limitations, Fear, Soothability, and Perceptual Sensitivity were generally associated with greater left frontal activation (rs≥.23, ps<0.05), while only Falling Reactivity was associated with greater right frontal activation (rs≤−.44, ps<0.05). Results suggest that variability in frontal EEG asymmetry is robustly associated with parental report measures of temperament in infancy. PMID:21829482

GNAQ mutation in a patient with metastatic mucosal melanoma.

Mucosal melanomas represent about 1% of all melanoma cases and classically have a worse prognosis than cutaneous melanomas. Due to the rarity of mucosal melanomas, only limited clinical studies with metastatic mucosal melanoma are available. Mucosal melanomas most commonly contain mutations in the gene CKIT, and treatments have been investigated using targeted therapy for this gene. Mutations in mucosal melanoma are less common than in cutaneous or uveal melanomas and occur in descending order of frequency as: CKIT (20%), NRAS (5%) or BRAF (3%). Mutations in G-alpha proteins, which are associated with activation of the mitogen-activated protein kinase pathway, have not been reported in mucosal melanomas. These G-alpha protein mutations occur in the genes GNAQ and GNA11 and are seen at a high frequency in uveal melanomas, those melanomas that begin in the eye. A 59-year old Caucasian male was diagnosed with a mucosal melanoma after evaluation for what was thought to be a hemorrhoid. Molecular analysis of the tumor revealed a GNAQ mutation. Ophthalmologic exam did not disclose a uveal melanoma. Here we report, to our knowledge, the first known case of GNAQ mutation in a patient with metastatic mucosal melanoma.

These G-alpha protein mutations occur in the genes GNAQ and GNA11 and are seen at a high frequency in uveal melanomas, those melanomas that begin in the eye. Case presentation A 59-year old Caucasian male was diagnosed with a mucosal melanoma after evaluation for what was thought to be a hemorrhoid. Molecular analysis of the tumor revealed a GNAQ mutation. Ophthalmologic exam did not disclose a uveal melanoma. Conclusion Here we report, to our knowledge, the first known case of GNAQ mutation in a patient with metastatic mucosal melanoma. PMID:25030020

Unicompartmental knee arthroplasty (UKA) can be a surgical treatment option for patients with high expectations regarding the post-operative level of physical activity. A systematic review was undertaken to answer three research questions: (1) is there an improvement of physical activity based on validated activity scores following UKA? (2) What are the sport disciplines and the sport patterns of UKA patients? (3) What are the pre- and post-operative sport participation rates and the return to activity rates of UKA patients? Following the PRISMA guidelines, EMBASE, MEDLINE, ISI Web of Science and the Cochrane Central Register of Controlled Trials were searched for studies reporting the level of sport and/or physical activity before and after UKA, and/or included at least one activity score before and after UKA. Seventeen studies were identified reporting on 2972 UKAs, of which 89 % were medial UKAs and 92 % were mobile-bearing implants, respectively. Ten studies reported a statistically significant improvement of physical activity following UKA according to the UCLA activity score, the Tegner activity score or the High Activity Arthroplasty Score, respectively. Hiking, cycling and swimming are the most common activities following UKA. Sport participation before the onset of restricting symptoms ranged from 64 to 93 % and slightly decreased by 2-9 % following UKA. The return to activity rate ranged from 87 to 98 %. Patients following UKA are physically active according to validated activity scores. A significant increase in low-impact activities and a decrease in high-impact activities after UKA was observed. Patients with a UKA regularly participate in sports; however, sport participation slightly decreased compared to pre-arthritic levels. This systematic review helps physicians to manage the expectations of patients regarding the level of physical activity following UKA. III.

The strengths and weaknesses of engineering education in research-intensive institutions are reported and key areas for developmental focus identified. The work is based on a questionnaire and session summaries used during a two-day international conference held at Imperial College London. The findings highlight several common concerns, such as the need to improve faculty motivation towards teaching, broaden the workplace skills of students, widen employer engagement in teaching and raise the relevance and value of scholarly activity in the discipline of engineering education. Examples of good practice used to address such issues are reported.

Recently, Dientamoeba fragilis has emerged as a significant and common enteropathogen. The majority of patients with dientamoebiasis present with gastrointestinal complaints and chronic symptoms are common. Numerous studies have successfully demonstrated parasite clearance, coupled with complete resolution of clinical symptoms following treatment with various antiparasitic compounds. Despite this, there is very little in vitro susceptibility data available for the organism. Benzimidazoles are a class of antiparasitic drugs that are commonly used for the treatment of protozoan and helminthic infections. Susceptibility testing was undertaken on four D. fragilis clinical isolates against the following benzimidazoles: albendazole, flubendazole, mebendazole, nocodazole, triclabendazole and thiabendazole. The activities of the antiprotozoal compounds at concentrations ranging from 2 μg/mL to 500 μg/mL were determined via cell counts of D. fragilis grown in xenic culture. All tested drugs showed no efficacy. The beta-tubulin transcript was sequenced from two of the D. fragilis isolates and amino acid sequences predicted a susceptibility to benzimidazoles. This is the first study to report susceptibility profiles for benzimidazoles against D. fragilis, all of which were not active against the organism. This study also found that beta-tubulin sequences cannot be used as a reliable marker for resistance of benzimidazoles in D. fragilis. PMID:25148459

Epidemiologic studies of physical activity among patients with end-stage renal disease (ESRD) are lacking. The aim of this study was to describe the patterns of physical activity among new dialysis patients in the United States. Multivariate logistic regression analyses examined associations of self-reported limitations in physical activity and exercise frequency with sociodemographic and clinical variables in 2,264 patients from Wave 2 of the Dialysis Morbidity and Mortality Study. Overall, 56% of patients exercised less than once a week, 75% reported severe limitations in vigorous activities, whereas 42% had severe limitations in moderate physical activities. Fewer limitations in moderate or vigorous activities correlated positively with male gender (odds-ratio [OR] = 1.61), black race OR =1.49), Hispanic ethnicity (OR = 2.39), serum albumin (OR = 1.69 per 1 g/L higher), positive affect (OR = 2.33), peritoneal dialysis (OR = 1.90), and negatively with age (OR = 0.67), heart failure (OR = 0.75), peripheral vascular disease (OR = 0.69), malnutrition (OR = 0.67), and depression (OR = 0.39). Patients reporting fewer limitations in moderate or vigorous activities (OR = 1.35 and 1.28, respectively), or frequent visits with a dietitian (2 to 3 times per week vs. less) (OR = 1.21) in the pre-ESRD period exercised more frequently. Limitations in physical activity are common among new ESRD patients and these, in part, are related to pre-existing cardiovascular disease, malnutrition, and mental health.

Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is the most common subtype of infectious pediatric encephalopathy in Japan. The exact pathogenesis of and the best therapeutic strategy for AESD are uncertain. We firstly performed a brain biopsy in a 2-year-old boy with AESD associated with RS viral infection, which revealed activated ameoboid microglia accumulation around degenerated neuron, and astrogliosis in the affected cortex. Glutamate released from activated microglia may play an important role in the pathogenesis of AESD, which is compatible with the previous report of magnetic resonance spectroscopy showing elevated glutamate.

Results of animal studies suggest that maternal immune activation during pregnancy causes deficiencies in fetal neurodevelopment. Infectious disease is the most common path to maternal immune activation during pregnancy. The goal of this study was to determine the occurrence of common infections, febrile episodes, and use of antibiotics reported by the mother during pregnancy and the risk for autism spectrum disorder (ASD) and infantile autism in the offspring. We used a population-based cohort consisting of 96 736 children aged 8 to 14 years and born from 1997 to 2003 in Denmark. Information on infection, febrile episodes, and use of antibiotics was self-reported through telephone interviews during pregnancy and early postpartum. Diagnoses of ASD and infantile autism were retrieved from the Danish Psychiatric Central Register; 976 children (1%) from the cohort were diagnosed with ASD. Overall, we found little evidence that various types of mild common infectious diseases or febrile episodes during pregnancy were associated with ASD/infantile autism. However, our data suggest that maternal influenza infection was associated with a twofold increased risk of infantile autism, prolonged episodes of fever caused a threefold increased risk of infantile autism, and use of various antibiotics during pregnancy were potential risk factors for ASD/infantile autism. Our results do not suggest that mild infections, febrile episodes, or use of antibiotics during pregnancy are strong risk factors for ASD/infantile autism. The results may be due to multiple testing; the few positive findings are potential chance findings.

To determine the prevalence of musculoskeletal, neurological, and balance problems in patients enrolled in early outpatient (phase II) cardiac rehabilitation. Data were assessed retrospectively for 284 consecutive patients who attended the phase II Mayo Clinic Cardiac Rehabilitation program from April 2005 to August 2006. All participants completed a questionnaire that identified the presence of musculoskeletal pain, history of falls, joint replacements, osteoporosis, neurological disorders, and difficulties in performing activities of daily living. Balance assessment was evaluated using the single leg stance and the tandem gait tests. Of the total study population (mean age, 62.1 +/- 12.3 years), 25% reported musculoskeletal pain. A significantly higher prevalence of pain was noted in women than men (37% vs 20%, P = .004) and in those > 65 years than those < or = 65 years (35% vs 17%, P = .001). Back (29%), knee (17%), and hip (8%) pain were the most common symptoms, in order of decreasing frequency. Pain was worse with any activity in 32% of participants while 16% of participants had worsening at night. An abnormality in balance was present in 58% of the study participants and was significantly more common in women (71%) and those > 65 years (83%). Falls or gait instability or both were reported by 11% of participants. Musculoskeletal and balance limitations are common in persons enrolled in early outpatient cardiac rehabilitation, particularly in women and patients > 65 years. Cardiac rehabilitation programs should screen patients for musculoskeletal limitations and incorporate adaptations for treatment strategies of such patients.

Background The reward deficiency syndrome hypothesis posits that genes are responsible for reward dependence and related behaviors. There is evidence that both bulimia and anorexia nervosa, especially in women, have been linked to a lifetime history of substance use disorder (SUD). There are difficulties in accepting food as an addiction similar to drugs; however, increasingly neuroimaging studies favor such an assertion. Case presentations We are reporting the evidence of comorbidity of eating disorders with SUD found within these case presentations. We show 50 case reports derived from two independent treatment centers in Florida that suggest the commonality between food and drug addictions. In an attempt to provide data from this cohort, many participants did not adequately respond to our questionnaire. Discussion We propose that dopamine agonist therapy may be of common benefit. Failure in the past may reside in too powerful D2 agonist activity leading to D2 receptor downregulation, while the new methodology may cause a reduction of "dopamine resistance" by inducing "dopamine homeostasis." While this is not a definitive study, it does provide some additional clinical evidence that these two addictions are not mutually exclusive. Conclusion Certainly, it is our position that there is an overlap between food- and drug-seeking behavior. We propose that the studies focused on an effort to produce natural activation of dopaminergic reward circuitry as a type of common therapy may certainly be reasonable. Additional research is warranted.

Objective : The purpose of this study is to describe the state of chiropractic continuing education vis-à-vis interprofessional education (IPE) with medical doctors (MD) in a survey of a sample of US doctors of chiropractic (DC) and through a review of policies. Methods : Forty-five chiropractors with experience in interprofessional settings completed an electronic survey of their experiences and perceptions regarding DC-MD IPE in chiropractic continuing education (CE). The licensing bodies of the 50 US states and the District of Columbia were queried to assess the applicability of continuing medical education (CME) to chiropractic relicensure. Results : The majority (89.1%) of survey respondents who attend CE-only events reported that they rarely to never experienced MD-IPE at these activities. Survey respondents commonly attended CME-only events, and 84.5% stated that they commonly to very commonly experienced MD-IPE at these activities. More than half (26 of 51) of the licensing bodies did not provide sufficient information to determine if CME was applicable to DC relicensure. Thirteen jurisdictions (25.5%) do not, and 12 jurisdictions (23.5%) do accept CME credits for chiropractic relicensure. Conclusion : The majority of integrated practice DCs we surveyed reported little to no IPE occurring at CE-only events, yet significant IPE occurring at CME events. However, we found only 23.5% of chiropractic licensing bodies allow CME credit to apply to chiropractic relicensure. These factors may hinder DC-MD IPE in continuing education.

To assess predictors of presenteeism (reduced productivity at work) and activity impairment outside work in patients with spondyloarthritis (SpA). Multivariate logistic regression analysis was used to study predictors of presenteeism and activity impairment in 1,253 patients with SpA based on a 2.5 year follow-up questionnaire. The Work Productivity and Activity Impairment (WPAI) questionnaire was used as main outcome. Age, gender, lifestyle factors, subgroups, disease duration, and different patient reported outcome measures (PROMs) were studied as possible predictors. The association between presenteeism and WPAI activity impairment outside work was assessed. Out of 1,253 patients, 757 reported being in work and of these 720 responded to the WPAI questionnaire. The mean (confidence interval, CI) reported presenteeism was 25% (23-27%) and mean activity impairment 33% (31-35%) (0-100%, 0 = no reduction). Significant predictors of presenteeism and activity impairment at follow-up (controlled for gender, age, spondyloarthritis subgroups and presenteeism at baseline) were presenteeism at baseline, poor quality of life, worse disease activity, decreased physical function, lower self-efficacy pain and symptom, higher scores of anxiety, depression, smoking and low education level, and for activity impairment also female sex. There was a strong association between presenteeism and activity impairment outside work (OR 16.7; 95% CI 11.6-24.3; p < 0.001). Presenteeism and activity impairment were not only predicted by presenteeism at baseline, but also by several PROMs commonly used in clinical rheumatology practice. Impaired activity outside work could indicate problems also at work suggesting why both areas need to be addressed in the clinical situation.

The ubiquitous protozoan parasites Giardia and Cryptosporidium have been detected from many species of captive and free-living wildlife, representing most mammalian orders. Twenty species of marine mammals have been reported to inhabit Galician waters and the region has one of the highest rates of stranding in Europe. Evidence from stranding, reported by-catches and sightings, suggests that the common dolphin (Delphinus delphis) is the most abundant cetacean on the Galician coast (Northwest Spain). The objective of this study was to detect and molecularly characterize isolates of Giardia and Cryptosporidium obtained from common dolphins stranded in this area. Between 2005 and 2012, sections of large intestine from 133 common dolphins stranded along the Galician coast were collected by the personnel of the Galician Stranding Network (Coordinadora para o Estudo dos Mamíferos Mariños, CEMMA). Using direct immunofluorescence antibody test (IFAT) and PCR amplification and sequencing of the SSU-rDNA, β-giardin genes and the ITS1-5.8S-ITS2 region, Giardia and Cryptosporidium were detected in 8 (6.0%) and 12 samples (9.0%), respectively. In two samples, co-infection by both parasites was observed. The molecular characterization revealed the presence of Giardia duodenalis assemblages A (genotypes A1 and A2) and B and Cryptosporidium parvum in these samples. This constitutes the first study in which the presence of Giardia and Cryptosporidium has been investigated in common dolphins on the European Atlantic coast, and it is also the first report of C. parvum in this host. Our findings indicate that these animals could act as reservoir of these waterborne parasites or could be victims of the contamination originated by anthropogenic activities.

2012-01-01

This study examines if electromyographic (EMG) amplitude differences exist between patients with shoulder instability and healthy controls performing scaption, prone horizontal abduction, prone external rotation, and push-up plus shoulder rehabilitation exercises. Thirty nine subjects were categorized by a single orthopedic surgeon as having multidirectional instability (n = 10), anterior instability (n = 9), generalized laxity (n = 10), or a healthy shoulder (n = 10). Indwelling and surface electrodes were utilized to measure EMG activity (reported as a % of maximum voluntary isometric contraction (MVIC)) in various shoulder muscles during 4 common shoulder exercises. The exercises studied effectively activated the primary musculature targeted in each exercise equally among all groups. The serratus anterior generated high activity (50–80% MVIC) during a push-up plus, while the infraspinatus and teres major generated moderate-to-high activity (30–80% MVIC) during both the prone horizontal and prone external rotation exercises. Scaption exercise generated moderate activity (20–50% MVIC) in both rotator cuff and scapular musculature. Clinicians should feel confident in prescribing these shoulder-strengthening exercises in patients with shoulder instability as the activation levels are comparable to previous findings regarding EMG amplitudes and should improve the dynamic stabilization capability of both rotator cuff and scapular muscles using exercises designed to address glenohumeral joint instability.

Statewide surveillance in California determined that the highest drowning rate from 1980 through 1989 was for the rural, desert county of Imperial (21.9 drownings per 100,000 population). To identify activities associated with drowning in this county, the authors abstracted data from the county sheriff-coroner's reports. From 1980 through 1990, there were 317 unintentional drownings; 85 percent occurred in irrigation canals. The activity prior to drowning was known for 262 persons (83 percent), and the most common activity was illegal entry into the United States. Overall, 140 persons (53 percent) were illegal entrants. Ninety-three percent of illegal entrants drowned in the All American Canal; the monthly drowning rate increased as the monthly average water velocity in the canal increased (r = 0.36; P < 0.001). Forty-eight persons (18 percent) drowned while riding in or on a land vehicle (automobile, pick-up truck, motorcycle, dune buggy, or tractor), the second most common activity associated with drowning. Seventy percent of the 23 drivers had an alcohol concentration of 100 milligrams per deciliter or more, California's limit for intoxication. To reduce drownings in Imperial County, prevention strategies should target persons engaged in at-risk activities near bodies of water. These strategies should include the identification and use of effective canal safety devices. PMID:8153281

A review of electroencephalographic changes in diabetes mellitus in relation to major depressive disorder.

2013-01-01

A bidirectional relationship exists between diabetes mellitus (DM) and major depressive disorder (MDD), with depression commonly reported in both type 1 DM (T1DM) and type 2 DM (T2DM), and depressive symptoms associated with a higher incidence of diabetes. However, how the two conditions are pathologically connected is not completely understood. Similar neurophysiological abnormalities have been reported in both DM and MDD, including elevated electroencephalographic (EEG) activity in low-frequency slow waves and increased latency and/or reduced amplitude of event-related potentials. It is possible that this association reflects some common underlying pathology, and it has been proposed that diabetes may place patients at risk for depression through a biological mechanism linking the metabolic changes of DM to changes in the central nervous system. In this review we will discuss EEG abnormalities in DM, as well as the biological mechanisms underlying various EEG parameters, in order to evaluate whether or not a common EEG biosignature exists between DM and MDD. Identifying such commonalities could significantly inform the current understanding of the mechanisms that subserve the development of the two conditions. Moreover, this new insight may provide the basis for informing new drug discovery capable of mitigating and possibly even preventing both conditions.

Dental infections, frequent in the general population, are a common cause of inflammation with systemic impact, and are the most common cause of orofacial pain. Temporomandibular disorders are also frequent in the elderly and represent an important cause of secondary headache. Both inflammation and pain can also contribute to cognitive, functional and behavioral impairment of the elderly and aggravate symptoms of patients with Alzheimer’s disease (AD). We report a case of a 74-year-old woman with AD and chronic facial pain who had a significant improvement in functional activities as well as in cognition and depressive symptoms after successful treatment of her facial pain. Patients with AD have higher compromise of oral health with infections and teeth loss. The investigation of orofacial pain should be performed in patients with AD, because of the associations reviewed and given the potential for improvement as highlighted by this case. PMID:29213678

To determine the compliance of middle school-aged babysitters with national recommendations for emergency preparedness and safety practices. A prospective, self-administered questionnaire-based study was conducted at 3 middle schools in central Pennsylvania. A total of 1364 questionnaires were available for analysis. Responding babysitters (n = 890) reported previous training that included babysitter (21%), first aid (64%), and cardiopulmonary resuscitation (59%) training. Reported unsafe babysitter practices were leaving a child unattended (36%) and opening the door to a stranger (24%). The most common emergency experience encountered by responding babysitters included cut or scrape (83%), burns (28%), and choking (14%). Ten percent of responding babysitters have activated the 911 system. Middle school-aged babysitters will likely encounter common household emergencies and therefore benefit from first aid training; however, very little difference in safety knowledge was found between trained and untrained babysitters, suggesting modifications in babysitter training programs may be required.

Research has linked sexual assault, substance use, and sexually transmitted infection (STI) risk in women. Sexual assault by means of verbal sexual coercion (VSC) is more common than sexual assault by means of physical tactics, but VSC is rarely assessed independently. In addition, past work has established global connections among substance use, sexual assault history, and STI risk; however, assessing substance use during sexual behavior is less common. This study examined the relations among VSC, STI risk behavior, and substance use and attitudes. We hypothesized that women with larger numbers of VSC experiences would report more frequent sexual risk behaviors and substance use and attitudes. Participants with larger numbers of VSC experiences reported larger numbers of anal sex partners, more frequent penile–vaginal sex and sexual activity after substance use, and stronger sex-related alcohol expectancies. These findings suggest that VSC is associated with higher levels of STI risk in women. PMID:26941549

Androgen responsiveness of Renilla luciferase reporter vectors is promoter, transgene, and cell line dependent.

Mulholland, David J; Cox, Michael; Read, Jason; Rennie, Paul; Nelson, Colleen

2004-05-01

Renilla based reporters are frequently used as transfection controls for luciferase transcriptional reporter assays. However, recent evidence suggests that a commonly used reporter (HSV-thymidine kinase driven Renilla) is responsive to androgen receptor (AR) and glucocorticoid receptors in the presence of the cognate ligands, dihydrotestosterone (DHT) and dexamethasone (DEX), respectively [1]. We further validate this important technical difficulty by illustrating that in LNCaP prostate cancer cells, spurious Renilla luciferase activity is a function of (a) the promoter driving Renilla expression, (b) the presence of co-transfected transgenes, and (c) the androgen responsiveness of the cell line used. Using inhibitors of transcription and translation we showed that transcript interference or translational modulation is not a major means by which androgens affect Renilla luciferase activity. As luciferase reporter assays are a frequent means of studying transcriptional co-regulation in the highly androgen dependent LNCaP cell line, our data serves as a cautionary note that alternative normalization techniques should be employed to avoid misinterpretation of data.

Background: When to allow an athlete to return to unrestricted sporting activity after anterior cruciate ligament (ACL) reconstruction remains controversial. Purpose: To report the results of functional performance testing reported in the literature for individuals at differing time points following ACL reconstruction and to examine differences between graft types. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of Medline, Scopus, and Cochrane Central Register of Controlled Trials was performed using PRISMA guidelines. Inclusion criteria were English-language studies that examined any functional rehabilitation test from 6 months to 2 years following ACL reconstruction. All patient-, limb-, and knee-specific demographics were extracted from included investigations. All functional rehabilitation tests were analyzed and compared when applicable. Results: The search term returned a total of 890 potential studies, with 88 meeting inclusion and exclusion criteria. A total of 4927 patients were included, of which 66% were male. The mean patient age was 26.5 ± 3.4 years. The predominant graft choices for reconstruction were bone–patellar tendon–bone (BPTB) autograft (59.8%) and hamstring autograft (37.9%). The most commonly reported functional tests were the hop tests. The results of these functional tests, as reported in the Limb Symmetry Index (LSI), improved with increasing time, with nearly all results greater than 90% at 1 year following primary ACL reconstruction. At 6 months postoperatively, a number of isokinetic strength measurements failed to reach 80% LSI, most commonly isokinetic knee extension testing in both BPTB and hamstring autograft groups. The knee flexion strength deficit was significantly less in the BPTB autograft group as compared with those having hamstring autograft at 1 year postoperatively, while no significant differences were found in isokinetic extension strength between the 2 groups. Conclusion: Hop testing was the most commonly reported functional test following ACL reconstruction. Increases in performance on functional tests were predictably seen as time increased following surgery. Those with hamstring autografts may experience increased strength deficits with knee flexion versus those having BPTB autograft. These data provide information that may assist providers in determining timing of return to unrestricted sporting activity. PMID:26535266

Barriers and enabling factors for work-site physical activity programs: a qualitative examination.

Work sites offer a productive setting for physical activity (PA) promoting interventions. Still, PA participation remains low. Thus, the purpose of this study was to examine the reasoning behind commonly reported barriers and enabling factors to participation in PA programs in a work-site setting. Employees from a large city government were recruited to participate in focus groups, stratified by white- and blue-collar occupations. Responses from open-ended questions about factors influencing participation in PA programs were audio recorded and transcribed verbatim. Resulting data were analyzed with open and axial coding. The sample consisted of 60 employees composing 9 focus groups. Although time was the most common barrier between both groups, white-collars workers responded that scheduling and work conflicts were the most common barrier concerning time. Blue-collar workers indicated shift work as their most common barrier. In addition, health was a significant enabling factor for both occupational categories. White-collar workers were much more concerned with appearances and were more highly motivated by weight loss and the hopefulness of quick results than were blue-collar workers. These findings are important in the understanding of PA as it relates to the reasoning behind participation in work-site programs in regard to occupational status.

The Human Rhinovirus (HRV) is the major aetiological agent for the common cold, for which only symptomatic treatment is available. HRV maturation and replication is entirely dependent on the activity of a virally encoded 3C protease that represents an attractive target for the development of therapeutics to treat the common cold. Herein we report the synthesis and biological evaluation of the 2-methylene analogue of the HRV 3C protease inhibitor (-)-thysanone (1) namely 2-carbathysanone (2), in an attempt to decipher the structural features in the natural product that are responsible for the 3C protease activity. 2-Carbathysanone (2) (and related analogues (±)-cis-23, (±)-cis-30, (±)-31) did not inhibit HRV 3C protease, indicating that the lactol functionality present in (-)-thysanone (1) is a critical structural feature required for inhibition.

Thiomicrospira species are ubiquitously found in various marine environments and appear particularly common in hydrothermal vent systems. Members of this lineage are commonly classified as sulfur-oxidizing chemolithoautotrophs. Although sequencing of Thiomicrospira crunogena's genome has revealed genes that encode enzymes for hydrogen uptake activity and for hydrogenase maturation and assembly, hydrogen uptake ability has so far not been reported for any Thiomicrospira species. We isolated a Thiomicrospira species (SP-41) from a deep sea hydrothermal vent and demonstrated that it can oxidize hydrogen. We show in vivo hydrogen consumption, hydrogen uptake activity in partially purified protein extracts and transcript abundance of hydrogenases during different growth stages. The ability of this strain to oxidize hydrogen opens up new perspectives with respect to the physiology of Thiomicrospira species that have been detected in hydrothermal vents and that have so far been exclusively associated with sulfur oxidation.

Is anthropogenic ambient noise in the ocean increasing?

McCarthy, Elena; Miller, James H.

It is commonly accepted that the ocean's ambient noise levels are rising due to increased human activities in coastal and offshore areas. It has been estimated that low-frequency noise levels increased more than 10 dB in many parts of the world between 1950 and 1975. [Ross, Acoustics Bulletin, Jan/Feb (1993)]. Several other sources cite an increase in manmade, or anthropogenic, noise over the past few decades. [D. A. Croll et al., Animal Conservation 4(1) (2001); Marine Mammal Commission Report to Congress (1999); C. W. Turl, NOSC Tech. Report 776 (1982)]. However, there are few historical records of ambient noise data to substantiate these claims. This paper examines several sectors of anthropogenic activities to determine their contributions to ambient noise. These activities include shipping, oil and gas exploration, military sonar development, and academic research. A series of indices for each of these industries is developed to predict ambient noise trends in the sea. It is found that the amount of noise generated by individual activities may have decreased overall due to new technologies and improved efficiency even if the intensity of such activities has increased.

Surgical residency has the reputation of being arduous and stressful. We sought to determine the stress levels of surgical residents, the major causes of stress and the coping mechanisms used. We developed and distributed a survey among surgical residents across Canada. A total of 169 participants responded: 97 (57%) male and 72 (43%) female graduates of Canadian (83%) or foreign (17%) medical schools. In all, 87% reported most of the past year of residency as somewhat stressful to extremely stressful, with time pressure (90%) being the most important stressor, followed by number of working hours (83%), residency program (73%), working conditions (70%), caring for patients (63%) and financial situation (55%). Insufficient sleep and frequent call was the component of residency programs that was most commonly rated as highly stressful (31%). Common coping mechanisms included staying optimistic (86%), engaging in enjoyable activities (83%), consulting others (75%) and exercising (69%). Mental or emotional problems during residency were reported more often by women (p = 0.006), who were also more likely than men to seek help (p = 0.026), but men reported greater financial stress (p = 0.036). Foreign graduates reported greater stress related to working conditions (p < 0.001), residency program (p = 0.002), caring for family members (p = 0.006), discrimination (p < 0.001) and personal and family safety (p < 0.001) than Canadian graduates. Time pressure and working hours were the most common stressors overall, and lack of sleep and call frequency were the most stressful components of the residency program. Female sex and graduating from a non-Canadian medical school increased the likelihood of reporting stress in certain areas of residency.

rGO supported CdS photocatalysts has been prepared by a two steps method, i.e. impregnation of GO/rGO with CdSO4 followed by a high temperature reaction with H2S gas. Activity of this catalyst was superior to a catalyst of same composition prepared by commonly reported hydrothermal technique. Detailed microstructure studies were carried out using FTIR, PL, DRS, XRD, TEM, SAED, TPO and XPS. A much greater chemical interaction at the interface of CdS and rGO and also a higher absorption of visible light were observed in the reported catalyst. It has been concluded that the high temperature reaction with H2S has imparted n-type semiconductivity to CdS which with p-type rGO and synergy of chemical interaction at the interface has resulted into formation of a p-n hetrojunction. The formation of hetrojunction and high electron mobility of rGO has given a superior activity due to an efficient charge separation to the catalyst prepared by the technique reported in this paper.

Activation of the Nrf2 Cell Defense Pathway by Ancient Foods: Disease Prevention by Important Molecules and Microbes Lost from the Modern Western Diet

The Nrf2 (NFE2L2) cell defense pathway protects against oxidative stress and disorders including cancer and neurodegeneration. Although activated modestly by oxidative stress alone, robust activation of the Nrf2 defense mechanism requires the additional presence of co-factors that facilitate electron exchange. Various molecules exhibit this co-factor function, including sulforaphane from cruciferous vegetables. However, natural co-factors that are potent and widely available from dietary sources have not been identified previously. The objectives of this study were to investigate support of the Nrf2 cell defense pathway by the alkyl catechols: 4-methylcatechol, 4-vinylcatechol, and 4-ethylcatechol. These small electrochemicals are naturally available from numerous sources but have not received attention. Findings reported here illustrate that these compounds are indeed potent co-factors for activation of the Nrf2 pathway both in vitro and in vivo. Each strongly supports expression of Nrf2 target genes in a variety of human cell types; and, in addition, 4-ethylcatechol is orally active in mice. Furthermore, findings reported here identify important and previously unrecognized sources of these compounds, arising from biotransformation of common plant compounds by lactobacilli that express phenolic acid decarboxylase. Thus, for example, Lactobacillus plantarum, Lactobacillus brevis, and Lactobacillus collinoides, which are consumed from a diet rich in traditionally fermented foods and beverages, convert common phenolic acids found in fruits and vegetables to 4-vinylcatechol and/or 4-ethylcatechol. In addition, all of the alkyl catechols are found in wood smoke that was used widely for food preservation. Thus, the potentially numerous sources of alkyl catechols in traditional foods suggest that these co-factors were common in ancient diets. However, with radical changes in food preservation, alkyl catechols have been lost from modern foods. The absence of alkyl catechols from the modern Western diet suggests serious negative consequences for Nrf2 cell defense, resulting in reduced protection against multiple chronic diseases associated with oxidative stress.

The standard approach for documenting symptomatic adverse events (AEs) in cancer clinical trials involves investigator reporting using the National Cancer Institute’s (NCI’s) Common Terminology Criteria for Adverse Events (CTCAE). Because this approach underdetects symptomatic AEs, the NCI issued two contracts to create a patient-reported outcome (PRO) measurement system as a companion to the CTCAE, called the PRO-CTCAE. This Commentary describes development of the PRO-CTCAE by a group of multidisciplinary investigators and patient representatives and provides an overview of qualitative and quantitative studies of its measurement properties. A systematic evaluation of all 790 AEs listed in the CTCAE identified 78 appropriate for patient self-reporting. For each of these, a PRO-CTCAE plain language term in English and one to three items characterizing the frequency, severity, and/or activity interference of the AE were created, rendering a library of 124 PRO-CTCAE items. These items were refined in a cognitive interviewing study among patients on active cancer treatment with diverse educational, racial, and geographic backgrounds. Favorable measurement properties of the items, including construct validity, reliability, responsiveness, and between-mode equivalence, were determined prospectively in a demographically diverse population of patients receiving treatments for many different tumor types. A software platform was built to administer PRO-CTCAE items to clinical trial participants via the internet or telephone interactive voice response and was refined through usability testing. Work is ongoing to translate the PRO-CTCAE into multiple languages and to determine the optimal approach for integrating the PRO-CTCAE into clinical trial workflow and AE analyses. It is envisioned that the PRO-CTCAE will enhance the precision and patient-centeredness of adverse event reporting in cancer clinical research. PMID:25265940

Bacterial vaginosis (BV) is a frequent cause of vaginal discharge that may be more common among women reporting sex with women (WSW). The objective of this study was to determine the prevalence of BV and predictors of infection among a sample of African American WSW. African American WSW aged 18 years or older presenting to the Mississippi State Department of Health STD Clinic between 2009 and 2010 and reporting a history of sexual activity with a female partner during the preceding year were invited to participate. A survey on sexual history and sexual behavior characteristics was completed. Bacterial vaginosis was defined by Amsel criteria. Associations with participant characteristics were determined using logistic regression analysis. Bacterial vaginosis was diagnosed in 93 (47.4%) of 196 women. Bisexual identity (odds ratio [OR], 1.94; 95% confidence interval [CI], 1.03-3.66; P = 0.04), douching within the past 30 days (OR, 1.93; 95% CI, 1.09-3.43; P = 0.02), age 18 years or less at first sexual encounter with a female partner (OR, 3.18; 95% CI, 1.16-8.71; P = 0.02), and report of more than 1 lifetime male sexual partners (OR, 1.94; 95% CI, 1.01-3.74; P = 0.04) were significant predictors of BV in bivariate analysis. Bacterial vaginosis was less common among women who reported more than 1 lifetime female sexual partner (OR, 0.26; 95% CI, 0.09-0.76; P = 0.01). In multivariable analysis, age 18 years or less at first sex with a female partner approached significance, while report of 1 lifetime female sexual partner remained strongly associated with BV. Bacterial vaginosis was common in this sample of African American WSW and significantly associated with report of 1 lifetime female sexual partner.

Introduction The prescription of physical activity for hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) can be complicated by the presence of comorbidities. The current research aimed to synthesize the relevant literature on the benefits of exercise for people with multimorbidities who experience an AECOPD, and ask: What are the parameters and outcomes of exercise in AECOPD and in conditions that are common comorbidities as reported by systematic reviews (SRs)? Methods An SR was performed using the Cochrane Collaboration protocol. Nine electronic databases were searched up to July 2011. Articles were included if they (1) described participants with AECOPD, chronic obstructive pulmonary disease (COPD), or one of eleven common comorbidities, (2) were an SR, (3) examined aerobic training (AT), resistance training (RT), balance training (BT), or a combination thereof, (4) included at least one outcome of fitness, and (5) compared exercise training versus control/sham. Results This synthesis examined 58 SRs of exercise training in people with AECOPD, COPD, or eleven chronic conditions commonly associated with COPD. Meta-analyses of endurance (aerobic or exercise capacity, 6-minute walk distance – 6MWD) were shown to significantly improve in most conditions (except osteoarthritis, osteoporosis, and depression), whereas strength was shown to improve in five of the 13 conditions searched: COPD, older adults, heart failure, ischemic heart disease, and diabetes. Several studies of different conditions also reported improvements in quality of life, function, and control or prevention outcomes. Meta-analyses also demonstrate that exercise training decreases the risk of mortality in older adults, and those with COPD or ischemic heart disease. The most common types of training were AT and RT. BT and functional training were commonly applied in older adults. The quality of the SRs for most conditions was moderate to excellent (>65%) as evaluated by AMSTAR scores. Conclusion In summary, this synthesis showed evidence of significant benefits from exercise training in AECOPD, COPD, and conditions that are common comorbidities. A broader approach to exercise and activity prescription in pulmonary rehabilitation may induce therapeutic benefits to ameliorate clinical sequelae associated with AECOPD and comorbidities such as the inclusion of BT and functional training.

Many patients with oral lichen planus (OLP) report triggers of flares, some of which overlap with triggers of other oral diseases, including oral allergy syndrome and oral contact dermatitis. The purpose of this study was to evaluate the prevalence of commonly reported triggers of OLP flares, their overlap with triggers of other oral diseases, and the potential role of trigger avoidance as a management strategy. Questionnaire-based survey of 51 patients with biopsy-proven lichen planus with oral involvement seen in an academic dermatology specialty clinic and/or oral pathology clinic between June 2014 and June 2015. Of the participants, 94% identified at least one trigger of their OLP flares. Approximately half of the participants (51%) reported at least one trigger that overlapped with known triggers of oral allergy syndrome, and 63% identified at least one trigger that overlapped with known triggers of oral contact dermatitis. Emotional stress was the most commonly reported trigger (77%). Regarding avoidance, 79% of the study participants reported avoiding their known triggers in daily life. Of those who actively avoided triggers, 89% reported an improvement in symptoms and 70% reported a decrease in the frequency of flares. Trigger identification and avoidance can play a potentially effective role in the management of OLP. Copyright © 2017 Elsevier Inc. All rights reserved.

This study describes the symptom experience of 570 older women with heart disease and evaluates a disease-management program's impact on symptoms over time. Women were randomly assigned to either usual care or a 4-week program ("Women take PRIDE") designed to improve self-regulation skills by focusing on increasing physical activity. At 4 months follow-up, program women, compared to controls, reported fewer total symptoms (p = 0.01) and decreased symptom frequency (p = 0.02) and bothersomeness (p = 0.02). By 12 months, positive intervention effects emerged within the common cardiac and sleep and rest symptom categories. Program group women reported more improvements in symptoms likely to be affected by increasing physical activity at both follow-ups (p < 0.05).

To examine the workplace food and physical activity (PA) environments and wellness culture reported by employed United States adults, overall and by employer size. Cross-sectional study using web-based survey on wellness policies and environmental supports for healthy eating and PA. Worksites in the United States. A total of 2101 adults employed outside the home. Survey items were based on the Centers for Disease Control and Prevention Worksite Health ScoreCard and Checklist of Health Promotion Environments and included the availability and promotion of healthy food items, nutrition education, promotion of breast-feeding, availability of PA amenities and programs, facility discounts, time for PA, stairwell signage, health promotion programs, and health risk assessments. Descriptive statistics were used to examine the prevalence of worksite environmental and facility supports by employer size (<100 or ≥100 employees). Chi-square tests were used to examine the differences by employer size. Among employed respondents with workplace food or drink vending machines, approximately 35% indicated the availability of healthy items. Regarding PA, 30.9% of respondents reported that their employer provided opportunities to be physically active and 17.6% reported worksite exercise facilities. Wellness programs were reported by 53.2% working for large employers, compared to 18.1% for smaller employers. Employee reports suggested that workplace supports for healthy eating, PA, and wellness were limited and were less common among smaller employers.

GM2 gangliosidosis associated with a HEXA missense mutation in Japanese Chin dogs: a potential model for Tay Sachs disease.

GM2 gangliosidosis is a fatal lysosomal storage disease caused by a deficiency of β-hexosaminidase (EC 3.2.1.52). There are two major isoforms of the enzyme: hexosaminidase A composed of an α and a β subunit (encoded by HEXA and HEXB genes, respectively); and, hexosaminidase B composed of two β subunits. Hexosaminidase A requires an activator protein encoded by GM2A to catabolize GM2 ganglioside, but even in the absence of the activator protein, it can hydrolyze the synthetic substrates commonly used to assess enzyme activity. GM2 gangliosidosis has been reported in Japanese Chin dogs, and we identified the disease in two related Japanese Chin dogs based on clinical signs, histopathology and elevated brain GM2 gangliosides. As in previous reports, we found normal or elevated hexosaminidase activity when measured with the synthetic substrates. This suggested that the canine disease is analogous to human AB variant of G(M2) gangliosidosis, which results from mutations in GM2A. However, only common neutral single nucleotide polymorphisms were found upon sequence analysis of the canine ortholog of GM2A from the affected Japanese Chins. When the same DNA samples were used to sequence HEXA, we identified a homozygous HEXA:c967G>A transition which predicts a p.E323K substitution. The glutamyl moiety at 323 is known to make an essential contribution to the active site of hexosaminidase A, and none of the 128 normal Japanese Chins and 92 normal dogs of other breeds that we tested was homozygous for HEXA:c967A. Thus it appears that the HEXA:c967G>A transition is responsible for the GM2 gangliosidosis in Japanese Chins. Copyright © 2012 Elsevier Inc. All rights reserved.

Sarcopenia, muscle weakness, and physical frailty are independent predictors of mortality in cirrhosis. These adverse prognostic factors are potentially modifiable with lifestyle interventions, including adequate nutritional intake and physical activity. Our aim was to identify patient-perceived barriers and enablers to these interventions. Adult patients with cirrhosis were prospectively recruited from two tertiary care liver clinics. Patients were excluded if they had hepatocellular carcinoma beyond transplant criteria, other active malignancy, or advanced chronic disease. A total of 127 patients (mean age: 60 ± 9 years, 58% males, and 48% with Child-Pugh-B/C (CP-B/C) disease) were included. Two-thirds of the patients had cirrhosis related to alcohol or hepatitis C. CP-B/C patients were more likely to take oral nutritional supplements (56% vs 29%) and less likely to consume animal protein daily (66% vs 85%) when compared to CP-A patients. Early satiety, altered taste, and difficulty in buying/preparing meals were more common in CP-B/C patients and even present in 20-30% of CP-A patients. Most patients reported adequate funds to purchase food. As quantified by the International Physical Activity Questionnaire-Short Form, 47% reported low activity levels, with no significant differences between groups. CP-B/C patients were more fatigued with exercise, however, overall Exercise Benefits/Barriers Scale scores were similar across groups. Barriers to nutritional intake and physical activity are common in cirrhosis and should be evaluated and treated in all patients. Asking simple screening questions in clinic and referring at-risk patients to expert multidisciplinary providers is a reasonable strategy to address these barriers. Future research should evaluate techniques to overcome modifiable barriers and enhance enablers.

The Food and Drug Administration (FDA) approved quadrivalent human papillomavirus vaccine (4vHPV) for use in females and males aged 9-26 years, since 2006 and 2009 respectively. We characterized reports to the Vaccine Adverse Event Reporting System (VAERS), a US spontaneous reporting system, in females and males who received 4vHPV vaccination. We searched VAERS for US reports of adverse events (AEs) following 4vHPV from January 2009 through December 2015. Signs and symptoms were coded using Medical Dictionary for Regulatory Activities (MedDRA). We calculated reporting rates and conducted empirical Bayesian data mining to identify disproportional reports. Clinicians reviewed available information, including medical records, and reports of selected pre-specified conditions. VAERS received 19,760 reports following 4vHPV; 60.2% in females, 17.2% in males, and in 22.6% sex was missing. Overall, 94.2% of reports were non-serious; dizziness, syncope and injection site reactions were commonly reported in both males and females. Headache, fatigue and nausea were commonly reported serious AEs. More than 60 million 4vHPV doses were distributed during the study period. Crude AE reporting rates were 327 reports per million 4vHPV doses distributed for all reports, and 19 per million for serious reports. Among 29 verified reports of death, there was no pattern of clustering of deaths by diagnosis, co-morbidities, age, or interval from vaccination to death. No new or unexpected safety concerns or reporting patterns of 4vHPV with clinically important AEs were detected. Safety profile of 4vHPV is consistent with data from pre-licensure trials and postmarketing safety data. Published by Elsevier Ltd.

Hypersexuality remains an increasingly common but poorly understood patient complaint. Despite diversity in clinical presentations of patients referred for hypersexuality, the literature has maintained treatment approaches that are assumed to apply to the entire phenomenon. This approach has proven ineffective, despite its application over several decades. The present study used quantitative methods to examine demographic, mental health, and sexological correlates of common clinical subtypes of hypersexuality referrals. Findings support the existence of subtypes, each with distinct clusters of features. Paraphilic hypersexuals reported greater numbers of sexual partners, more substance abuse, initiation to sexual activity at an earlier age, and novelty as a driving force behind their sexual behavior. Avoidant masturbators reported greater levels of anxiety, delayed ejaculation, and use of sex as an avoidance strategy. Chronic adulterers reported premature ejaculation and later onset of puberty. Designated patients were less likely to report substance abuse, employment, or finance problems. Although quantitative, this article nonetheless presents a descriptive study in which the underlying typology emerged from features most salient in routine sexological assessment. Future studies might apply purely empirical statistical techniques, such as cluster analyses, to ascertain to what extent similar typologies emerge when examined prospectively.

Determining the structure of an optimal personnel profile for a transformed commission

Graniere, R.J.

1998-06-01

In the classic sociological sense, an organization such as a public utility commission is a social unit consisting of specific groupings constructed and reconstructed deliberately and with forethought to achieve specific goals. These organizational groupings determined on the basis of rational divisions of labor, power, and communication are designed with the objective of placing individuals into positions where they are expected to make the largest contribution towards achieving the organization`s goals. It is reasonable then to conclude that proponents of the classical view had in mind a readily identifiable common ground among the organization`s members that the organization exploits asmore » it selects its goals. Recently, it has been argued that metaphors are an acceptable shorthand for this common ground that provides an insight into the types of personnel an organization would find most suitable for assisting its efforts to reach its goals. This report is one of a series of reports on the transformation of public utility commissions. Previous reports in the series have focused on the transformation of a commission`s culture, roles, and activities. This report focuses on the staffing dimension of the personnel mix needed to support these changes.« less

Monitoring is integral to adequately recognise and track mental health indicators of symptoms and functioning. Early identification of warning signs from digital footprints could facilitate adaptive and dynamic just in-time monitoring and care for individuals with common mental disorders. Self-report data on mental health and lifestyle behaviour from 120 male and female Australian young adults experiencing psychological distress were collected online. API software was used to download participant's daily activity duration measurements over eight months from linked commercial activity tracker apps and wearables in real time. An independent samples t-test was conducted to compare the differences in daily durations of recorded physical activity between wearable devises and smartphone apps. Entropy techniques using R interpol package were used to analyse volatility in daily activity duration. DASS-21 depression, stress and anxiety sub-scale scores indicated the study sample on average, had a moderate level of psychological distress. Daily activity duration was significantly greater from wearable devices when compared with smartphone apps (t-test = 25.4, p < 0.001). Entropy indices were not related with any of the DASS-21 measures. However, significant correlation between DASS-21 anxiety subscale scores and entropy of those with over 45 days measurements (r = 0.58, p = 0.02) was observed. The observational nature of this study prohibits causal inference. As a convenience sample was used, the results may lack generalisability to the wider population. Continuous monitoring using commercial apps and wearables as a resource to help clinicians augment clinical care for common mental disorders appears viable. Copyright © 2018.

Introduction Self-report physical activity assessment tools are commonly used for the evaluation of physical activity levels in individuals with stroke. A great variety of these tools have been developed and widely used in recent years, which justify the need to examine their measurement properties and clinical utility. Therefore, the main objectives of this systematic review are to examine the measurement properties and clinical utility of self-report measures of physical activity and discuss the strengths and limitations of the identified tools. Methods and analysis A systematic review of studies that investigated the measurement properties and/or clinical utility of self-report physical activity assessment tools in stroke will be conducted. Electronic searches will be performed in five databases: Medical Literature Analysis and Retrieval System Online (MEDLINE) (PubMed), Excerpta Medica Database (EMBASE), Physiotherapy Evidence Database (PEDro), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Scientific Electronic Library Online (SciELO), followed by hand searches of the reference lists of the included studies. Two independent reviewers will screen all retrieve titles, abstracts, and full texts, according to the inclusion criteria and will also extract the data. A third reviewer will be referred to solve any disagreement. A descriptive summary of the included studies will contain the design, participants, as well as the characteristics, measurement properties, and clinical utility of the self-report tools. The methodological quality of the studies will be evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist and the clinical utility of the identified tools will be assessed considering predefined criteria. This systematic review will follow the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. Discussion This systematic review will provide an extensive review of the measurement properties and clinical utility of self-report physical activity assessment tools used in individuals with stroke, which would benefit clinicians and researchers.

Background: The purpose of this study was to evaluate the extent, if any, that the association between socio-ecological parameters and physical activity may be influenced by common method bias (CMB). Methods: This study took place between February and May of 2017 at a Southeastern University in the United States. A randomized controlled experiment was employed among 119 young adults.Participants were randomized into either group 1 (the group we attempted to minimize CMB)or group 2 (control group). In group 1, CMB was minimized via various procedural remedies,such as separating the measurement of predictor and criterion variables by introducing a time lag (temporal; 2 visits several days apart), creating a cover story (psychological), and approximating measures to have data collected in different media (computer-based vs. paper and pencil) and different locations to control method variance when collecting self-report measures from the same source. Socio-ecological parameters (self-efficacy; friend support; family support)and physical activity were self-reported. Results: Exercise self-efficacy was significantly associated with physical activity. This association (β = 0.74, 95% CI: 0.33-1.1; P = 0.001) was only observed in group 2 (control), but not in group 1 (experimental group) (β = 0.03; 95% CI: -0.57-0.63; P = 0.91). The difference in these coefficients (i.e., β = 0.74 vs. β = 0.03) was statistically significant (P = 0.04). Conclusion: Future research in this field, when feasible, may wish to consider employing procedural and statistical remedies to minimize CMB.

Prospective multifactorial study on low back pain (LBP) in adolescents. Most studies on LBP have focused on adults although many investigations have shown that the roots of LBP lie in adolescence. Several mechanical, physical, and behavioral factors have been associated with nonspecific LBP in adolescents. To investigate the effect of all previously reported parameters together with psychological and psychosocial factors using advanced statistics, on LBP in adolescents aged 15 to 19 years. Six hundred and eighty-eight students aged 16±1 years from 5 randomly selected high schools participated in this study and completed a questionnaire containing questions on daily activity, backpack carrying, psychological and psychosocial behavior. Anthropometric data as well as biplane spinal curvatures together with questionnaire results were included in the analysis using advanced statistics. LBP reported 41% of the participants. Generally, statistically significant correlations were found between LBP (0.002), physical activity (P<0.001), physician consultation (P=0.024), and depression (P<0.001). Sex-related differences were shown regarding LBP intensity (P=0.005) and frequency (P=0.013), stress (P<0.03), depression (P=0.005), and nervous mood (P=0.036) in favor of male students. Male adolescents had continuous energy (P=0.0258) and were calm (P=0.029) in contrast with female counterparts. LBP was sex-related and was less common in adolescents with frequent activity. Adolescent girls with stress, depressive mood, and low energy have more LBP than boys, which makes physician consultation for LBP more common in female adolescents. Systematic physical activity and control of psychological profile should decrease LBP frequency and intensity.

Despite recent advances in food production technology, food-borne diseases (FBD) remain a challenging public health concern. In several countries, including Brazil, Clostridium perfringens is among the five main causative agents of food-borne diseases. The present study determines antimicrobial activities of essential oils of six condiments commonly used in Brazil, viz., Ocimum basilicum L. (basil), Rosmarinus officinalis L. (rosemary), Origanum majorana L. (marjoram), Mentha × piperita L. var. Piperita (peppermint), Thymus vulgaris L. (thyme) and Pimpinella anisum L. (anise) against C. perfringens strain A. Chemical compositions of the oils were determined by GC-MS (gas chromatography-mass spectrometry). The identities of the isolated compounds were established from the respective Kováts indices, and a comparison of mass spectral data was made with those reported earlier. The antibacterial activity was assessed from minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) using the microdilution method. Minimum inhibitory concentration values were 1.25mgmL(-1) for thyme, 5.0mgmL(-1) for basil and marjoram, and 10mgmL(-1) for rosemary, peppermint and anise. All oils showed bactericidal activity at their minimum inhibitory concentration, except anise oil, which was only bacteriostatic. The use of essential oils from these common spices might serve as an alternative to the use of chemical preservatives in the control and inactivation of pathogens in commercially produced food systems.

Epidemiology of non-submersion injuries in aquatic sporting and recreational activities.

Chalmers, David; Morrison, Luke

2003-01-01

Although the issues of drowning and near-drowning in aquatic sporting and recreational activities receive considerable attention in the epidemiological literature, there is not a recognised literature on non-submersion injuries occurring in these activities. This review draws together the epidemiological literature on non-submersion injuries and describes the incidence, nature and causes of these injuries, common risk factors, and strategies for prevention. Activities covered by the review include swimming, diving, boating, surf sports, fishing, water polo and water sliding. For most activities there is a dearth of good quality descriptive studies, with most involving cases-series designs and few providing estimates of incidence. Inconsistencies in inclusion criteria and the reporting of incidence rates makes comparisons within and between activities difficult. Incidence rates were identified for most activities and in general the incidence of injury was low, especially for more serious injury. However, some activities were associated with severely disabling injury, such as spinal cord injury (diving) and amputation (from propeller strikes in water skiing and swimming). Only three studies reporting the significance of postulated risk factors were identified. Lack of knowledge about the water being entered and alcohol consumption are significant risk factors in recreational diving; increased blood alcohol concentrations were reported to increase the risk of death in boating; and obesity and tandem riding were reported to increase the risk of injury on public water slides. Few evaluations of preventive measures were identified. Two studies reported reductions in the incidence of water slide injuries following the introduction of design changes and supervision, but neither had a non-intervention comparison group. Improvements in swimming and diving skills were reported in three studies, but these were not designed to measure changes in the risk of injury.This review demonstrates that there is a need for well-designed epidemiological research on non-submersion injury in aquatic sporting and recreational activities. The first priority should be for studies designed to describe accurately the incidence, nature, severity and circumstances of these injuries, followed by research on the significance of postulated risk factors. Once this research has been undertaken, interventions targeted at reducing the incidence of injury in aquatic sporting and recreational activities can be designed and evaluated.

Cognitive impairment in individuals with multiple sclerosis (MS) is now well recognized. One of the most common cognitive deficits is found in memory functioning, largely due to impaired acquisition. We examined functional brain activity 6 months after memory retraining in individuals with MS. The current report presents long term follow-up results from a randomized clinical trial on a memory rehabilitation protocol known as the modified Story Memory Technique. Behavioral memory performance and brain activity of all participants were evaluated at baseline, immediately after treatment, and 6 months after treatment. Results revealed that previously observed increases in patterns of cerebral activation during learning immediately after memory training were maintained 6 months post training.

Photoelectrocyclization as an activation mechanism for organelle-specific live-cell imaging probes.

Tran, Mai N; Chenoweth, David M

2015-05-26

Photoactivatable fluorophores are useful tools in live-cell imaging owing to their potential for precise spatial and temporal control. In this report, a new photoactivatable organelle-specific live-cell imaging probe based on a 6π electrocyclization/oxidation mechanism is described. It is shown that this new probe is water-soluble, non-cytotoxic, cell-permeable, and useful for mitochondrial imaging. The probe displays large Stokes shifts in both pre-activated and activated forms, allowing simultaneous use with common dyes and fluorescent proteins. Sequential single-cell activation experiments in dense cellular environments demonstrate high spatial precision and utility in single- or multi-cell labeling experiments. © 2015 WILEY-VCH Verlag GmbH & Co.

Bacopa monniera Wettst. (syn. Herpestis monniera L.; Scrophulariaceae) is a commonly used Ayurvedic drug for mental disorders. The standardized extract was reported earlier to have significant anti-oxidant effect, anxiolytic activity and improve memory retention in Alzheimer's disease. Presently, the standardized methanolic extract of Bacopa monniera (bacoside A - 38.0+/-0.9) was investigated for potential antidepressant activity in rodent models of depression. The effect was compared with the standard antidepressant drug imipramine (15 mg/kg, ip). The extract when given in the dose of 20 and 40 mg/kg, orally once daily for 5 days was found to have significant antidepressant activity in forced swim and learned helplessness models of depression and was comparable to that of imipramine.

A decrease in the specific activity of an enzyme is commonly observed when the enzyme is inappropriately handled or is stored over an extended period. Here, we reported a functional transition of an FMN-bound diaphorase (FMN-DI) that happened during the long-term storage process. It was found that FMN-DI did not simply lose its β-nicotinamide adenine diphosphate (NADH) dehydrogenase activity after a long-time storage, but obtained a new enzyme activity of NADH oxidase. Further mechanistic studies suggested that the alteration of the binding strength of an FMN cofactor with a DI protein could be responsible for this functional switch of the enzyme. © 2017 International Union of Biochemistry and Molecular Biology, Inc.

The objectives of this study were to identify the number and types of recreational injuries sustained by visitors to Mount Rainier National Park and Olympic National Park in Washington State and to compare the nature of injuries sustained by children compared with adults. We retrospectively reviewed case incident reports obtained by rangers in Mount Rainer National Park and Olympic National Park between 1997 and 2001. Data collected included victim age, gender, date of injury, activity preinjury, type of injury, and mechanism of injury. There were 535 cases of recreational wilderness injuries (including 19 total deaths), yielding a rate of 22.4 injuries per million visits. The mean age of injury victims was 34 years. Males were more likely to sustain injury than were females (59% vs 41%). Most injuries occurred during summer months between noon and 6:00 PM, and 90% occurred during daylight hours. The most common preinjury activities included hiking (55%), winter sports (15%), and mountaineering (12%), and the most common types of injuries included sprains, strains and soft tissue injuries (28%), fractures or dislocations (26%), and lacerations (15%). A total of 121 (23%) of the injuries occurred in children (<18 years of age). There were 19 deaths in the 2 national parks (18 men, 1 woman); all victims were adults. Hiking (58%) and mountaineering (26%) were the most common activities at the time of death. Mechanism of death included falls (37%), medical (eg, myocardial infarction) (21%), drowning (5%), and suicide (5%). The most common type of injury was soft tissue injury, and injuries occurred most commonly while hiking, during daylight hours, and in the summer. Preinjury activities and types of injuries were different in children compared with adults. Knowledge of how and when injuries occur in national parks can assist in determining what resources are needed to help provide a safer environment for park visitors. This study may also aid prevention strategies in the national parks, guide training of rangers, aid in the preparation of first aid kits, and further the education of people who participate in wilderness activities.

Lag threads organize the brain’s intrinsic activity

Mitra, Anish; Snyder, Abraham Z.; Blazey, Tyler; Raichle, Marcus E.

2015-01-01

It has been widely reported that intrinsic brain activity, in a variety of animals including humans, is spatiotemporally structured. Specifically, propagated slow activity has been repeatedly demonstrated in animals. In human resting-state fMRI, spontaneous activity has been understood predominantly in terms of zero-lag temporal synchrony within widely distributed functional systems (resting-state networks). Here, we use resting-state fMRI from 1,376 normal, young adults to demonstrate that multiple, highly reproducible, temporal sequences of propagated activity, which we term “lag threads,” are present in the brain. Moreover, this propagated activity is largely unidirectional within conventionally understood resting-state networks. Modeling experiments show that resting-state networks naturally emerge as a consequence of shared patterns of propagation. An implication of these results is that common physiologic mechanisms may underlie spontaneous activity as imaged with fMRI in humans and slowly propagated activity as studied in animals.

Common brain regions underlying different arithmetic operations as revealed by conjunct fMRI-BOLD activation.

PubMed

Fehr, Thorsten; Code, Chris; Herrmann, Manfred

2007-10-03

The issue of how and where arithmetic operations are represented in the brain has been addressed in numerous studies. Lesion studies suggest that a network of different brain areas are involved in mental calculation. Neuroimaging studies have reported inferior parietal and lateral frontal activations during mental arithmetic using tasks of different complexities and using different operators (addition, subtraction, etc.). Indeed, it has been difficult to compare brain activation across studies because of the variety of different operators and different presentation modalities used. The present experiment examined fMRI-BOLD activity in participants during calculation tasks entailing different arithmetic operations -- addition, subtraction, multiplication and division -- of different complexities. Functional imaging data revealed a common activation pattern comprising right precuneus, left and right middle and superior frontal regions during all arithmetic operations. All other regional activations were operation specific and distributed in prominently frontal, parietal and central regions when contrasting complex and simple calculation tasks. The present results largely confirm former studies suggesting that activation patterns due to mental arithmetic appear to reflect a basic anatomical substrate of working memory, numerical knowledge and processing based on finger counting, and derived from a network originally related to finger movement. We emphasize that in mental arithmetic research different arithmetic operations should always be examined and discussed independently of each other in order to avoid invalid generalizations on arithmetics and involved brain areas.

Regular physical activity may be an important contributor to psychological well-being. This link has not been explored in ethnically distinct, low- and middle-income countries (LMIC), especially in countries affected by war. This study aimed to examine the relationship between physical activity and levels of psychological distress in an epidemiological cross-representative sample of Vietnamese living in the Mekong Delta region of Vietnam. The sample was drawn from an urban (Cn Th City) and a rural (H u Giang) region, using a multi-stage probabilistic cluster sampling frame. The measures applied included the Composite International Diagnostic Interview (CIDI 2.0) yielding 12-month prevalence rates of common mental disorders, including anxiety, mood and substance use disorders; the Phan Vietnamese Psychiatric Scale (PVPS), a culturally specific self-report measure; and the Harvard Trauma Questionnaire. The Global Physical Activity Questionnaire (GPAQ version 1) was used to measure activity. Analyses were conducted using SAS software v.9.1.3. The population was assigned to three (high, moderate and low) physical activity levels. Analyses included chi-square tests and univariable and multivariable logistic models. Physical activity was greater in males, the middle-aged group (30-54 years), those who were married, the rural population, less educated individuals and those who were employed. High physical activity was significantly associated with low levels of psychological distress (indexed by a combination of CIDI and PVPS cases identified) when controlling for socio-demographic factors and number of medical conditions). Membership of the lowest of the three physical activity groups was associated with a psychological distress odds ratio of 2.19 (95% CI 1.28-3.75). The results remained consistent when analyses were undertaken separately for males and females. Low levels of physical activity appear to be associated with greater psychological distress in the Mekong Delta of Vietnam. The association remained after adjusting for the influence of socio-demographic characteristics, exposure to past trauma, urban-rural residency and the presence of self-reported physical disorders. These data provide a foundation for exploring the role of physical activity as an adjunct to conventional interventions for common mental disorders in resource-poor LMIC countries.

Relationships of multitasking, physicians' strain, and performance: an observational study in ward physicians.

Simultaneous task performance ("multitasking") is common in hospital physicians' work and is implicated as a major determinant for enhanced strain and detrimental performance. The aim was to determine the impact of multitasking by hospital physicians on their self reported strain and performance. A prospective observational time-and-motion study in a Community Hospital was conducted. Twenty-seven hospital physicians (surgical and internal specialties) were observed in 40 full-shift observations. Observed physicians reported twice on their self-monitored strain and performance during the observation time. Associations of observed multitasking events and subsequent strain and performance appraisals were calculated. About 21% of the working time physicians were engaged in simultaneous activities. The average time spent in multitasking activities correlated significantly with subsequently reported strain (r = 0.27, P = 0.018). The number of instances of multitasking activities correlated with self-monitored performance to a marginally significant level (r = 0.19, P = 0.098). Physicians who engage in multitasking activities tend to self-report better performance but at the cost of enhanced psychophysical strain. Hence, physicians do not perceive their own multitasking activities as a source for deficient performance, for example, medical errors. Readjustment of workload, improved organization of work for hospital physicians, and training programs to improve physicians' skills in dealing with multiple clinical demands, prioritization, and efficient task allocation may be useful avenues to explore to reduce the potentially negative impact of simultaneous task performance in clinical settings.

Increasing bacterial resistance to common drugs is a major public health concern for the treatment of infectious diseases. Certain naturally occurring compounds of plant sources have long been reported to possess potential antimicrobial activity. This study was aimed to investigate the antibacterial activity and possible mechanism of action of andrographolide (Andro), a diterpenoid lactone from a traditional medicinal herb Andrographis paniculata. Extent of antibacterial action was assessed by minimal bactericidal concentration method. Radiolabeled N-acetyl glucosamine, leucine, thymidine, and uridine were used to determine the effect of Andro on the biosyntheses of cell wall, protein, DNA, and RNA, respectively. In addition, anti-biofilm potential of this compound was also tested. Andro showed potential antibacterial activity against most of the tested Gram-positive bacteria. Among those, Staphylococcus aureus was found to be most sensitive with a minimal inhibitory concentration value of 100 μg/mL. It was found to be bacteriostatic. Specific inhibition of intracellular DNA biosynthesis was observed in a dose-dependent manner in S. aureus. Andro mediated inhibition of biofilm formation by S. aureus was also found. Considering its antimicrobial potency, Andro might be accounted as a promising lead for new antibacterial drug development.

To conduct an epidemiological investigation of an idiopathic myopathy, known as "Go Slow" (GSM), which was initially recognised in dogs used for pig hunting. A secondary aim was to describe the hunting activities, diet and health of dogs used for pig hunting in New Zealand. A retrospective cohort study was conducted between June 2014-June 2017. Cases of GSM in dogs were diagnosed by veterinarians using a combination of clinical history, physical examination findings, serum biochemistry and/or skeletal muscle histology. A telephone interview was conducted with the owner or primary veterinarian to provide information regarding the dog's diet and exercise over the 7 days preceding the onset of clinical signs. In August 2015, a separate online survey of owners of dogs used for pig hunting was conducted to characterise the normal hunting activities, diet and health of these dogs. A total of 86 cases of GSM were recruited, of which 58 (67%) were pig hunting dogs, 16 (19%) pet dogs and 12 (14%) working farm dogs. Cases were most commonly reported in the upper North Island, and 65 (76 (95% CI=67-85)%) were from the Northland region. Processed commercial dog food had been fed to 93 (95% CI=88-98)% of affected dogs. Ingestion of raw, frozen or cooked wild pig in the preceding week was reported for 76 (88 (95% CI=82-95)%) dogs with the myopathy. In the survey of owners of healthy pig hunting dogs, 203 eligible responses were received; pig hunting was reported to most commonly occur in Northland (20.2%), Waikato (22.3%) and Bay of Plenty (23.2%) regions. Commercial dog food was fed to 172 (85 (95% CI=80-90)%) of the dogs included in this survey, and 55 (27 (95% CI=20-33)%) had eaten wild pig in the preceding week. The most common reported health problem in pig hunting dogs was traumatic wounds. Cases of GSM were most commonly recognised in dogs used for pig hunting, but also occurred in pet and working farm dogs. The disease was most frequently reported in the upper North Island of New Zealand and ingestion of wild pig was a consistent feature in cases of this myopathy. To minimise the risk of dogs developing this myopathy, it would seem prudent to avoid feeding any tissues from wild pigs to dogs in areas where the disease is known to occur.

New low back pain in nurses: work activities, work stress and sedentary lifestyle.

Low back pain is common among nurses. Previous studies have shown that the risk of low back pain increases rapidly with greater amounts of physical work and psychological stress, but is inversely related to leisure activities. However, these previous studies were predominantly retrospective in design and not many took account of three factors simultaneously. This 12-month prospective study examined the relationships between work activities, work stress, sedentary lifestyle and new low back pain. A total of 144 nurses from six Hong Kong district hospitals completed a face-to-face baseline interview, which was followed-up by a telephone interview. The main study measures were demographic characteristics, work activities, work stress, physical leisure activities and the nature of new low back pain during the 12-month follow-up period. Level of work stress, quality of relationships at work, level of enjoyment experienced at work, and work satisfaction were self-reported. Fifty-six (38.9%) nurses reported experiencing new low back pain. Sedentary leisure time activity was not associated with new low back pain. Being comparatively new on a ward (adjusted relative risk 2.90), working in bending postures (adjusted relative risk 2.76) and poor work relationships with colleagues (adjusted relative risk 2.52) were independent predictors of new low back pain. The findings of this study suggest that low back pain is a common problem in the population of nurses in Hong Kong. Being comparatively new on a ward, bending frequently during work and having poor work relationships with colleagues are independent predictors of new low back pain. Training for high-risk work activities and ergonomic assessment of awkward work postures are essential. Moreover, relaxation and team-building workshops for nurses, especially those who are less experienced in the type of work on their current ward, are recommended.

Use of Actigraphy for Assessment in Pediatric Sleep Research

2011-01-01

The use of actigraphs, or ambulatory devices that estimate sleep-wake patterns from activity levels, has become common in pediatric research. Actigraphy provides a more objective measure than parent-report, and has gained popularity due to its ability to measure sleep-wake patterns for extended periods of time in the child’s natural environment. The purpose of this review is: (1) to provide comprehensive information on the historic and current uses of actigraphy in pediatric sleep research; (2) to review how actigraphy has been validated among pediatric populations; and (3) offer recommendations for methodological areas that should be included in all studies that utilize actigraphy, including the definition and scoring of variables commonly reported. The poor specificity to detect wake after sleep onset was consistently noted across devices and age groups, thus raising concerns about what is an “acceptable” level of specificity for actigraphy. Other notable findings from this review include the lack of standard scoring rules or variable definitions. Suggestions for the use and reporting of actigraphy in pediatric research are provided.

To review the literature on the susceptibility of common community pathogens in sub-Saharan Africa and Asia to the macrolide antibiotics. Inclusion criteria required that isolates were collected since 2004 to ensure results were of contemporary relevance. The data were aggregated by region, age group and sterility of site of culture sample. A total of 51 studies were identified, which reported the macrolide antimicrobial susceptibilities of common bacterial pathogens isolated since 2004. In general, there was less macrolide resistance in African than in Asian isolates. Most African studies reported high levels of macrolide susceptibility in Streptococcus pneumoniae, whereas most Chinese studies reported high levels of resistance. There was very little information available for Gram-negative organisms. Susceptibility of the pneumococcus to macrolides in SSA remains high in many areas, and good activity of azithromycin has been shown against Salmonellae spp. in Asia. In urban areas where high antibiotic consumption is prevalent, there was evidence of increased resistance to macrolides. However, there is no information on susceptibility from large areas in both continents. © 2011 Blackwell Publishing Ltd.

We examined the socio-demographic and behavioral determinants of perceived barriers to leisure-time physical activity (LTPA) in a population-based sample of working-aged adults. Data comprised the National FINRISK 2002 Study, a population-based health examination study. Analyses were restricted to those aged 25-64 years and who perceived that their amount of LTPA did not reach sufficient levels. They reported barriers to LTPA, defined as a lack of time, motivation and lack of companionship to be active with, as well as high expenses. Age, education, household income, employment status, family type, physical activity, smoking and body mass index (BMI) were included as explanatory variables. Lack of time was the most frequent barrier. Each barrier was explained by a different set of factors that also varied between genders. The strongest and most systematic associations with the barriers were found for age, employment status and family type. Lack of time was less often reported as a barrier among the unemployed, singles without children and older people. Lacking motivation as a barrier was most common among singles without children. High expenses as a barrier was more often reported by the unemployed, and less often reported in the highest income group. When considering actions to promote LTPA, there is not one single solution, because the perceived barriers vary by population subgroups. © 2015 the Nordic Societies of Public Health.

CMD was measured using the General Health Questionnaire. Total leisure-time activity and percentage of time spent in heavy-intensity activity were estimated from self-reports (Minnesota Leisure Time Physical Activity Questionnaire). Men were classified into four classes of occupational activity. Among 1,158 men with complete data, those who participated in any heavy-intensity leisure-time activity had reduced odds of CMD 5 years later (below median vs. none: adjusted odds ratio (OR(adj)) = 0.61, 95% confidence interval (CI): 0.40, 0.93); median or above vs. none: OR(adj) = 0.54, 95% CI: 0.35, 0.83). Analyses using multiple imputation to deal with missing data found weaker evidence for an association (OR(adj) = 0.79 (95% CI: 0.54, 1.15) and OR(adj) = 0.73 (95% CI: 0.49, 1.09), respectively). There was little evidence that men in the most physically demanding jobs had reduced odds of CMD after 5 years, and there was no association between physical activity and CMD 10 years later. Among these men, heavy-intensity leisure-time physical activity was associated with a small reduction in CMD over 5 years.

To date almost 200 genes were found to be associated with major depressive disorder (MDD) or suicide attempts (SA), but very few genes were reported for their molecular mechanisms. This study aimed to find out whether there were common or rare variants in three candidate genes altering the risk for MDD and SA in Chinese. Three candidate genes (HOMER1, SLC6A4 and TEF) were chosen for resequencing analysis and association studies as they were reported to be involved in the etiology of MDD and SA. Following that, bioinformatics analyses were applied on those variants of interest. After resequencing analysis and alignment for the amplicons, a total of 34 common or rare variants were found in the randomly selected 36 Hong Kong Chinese patients with both MDD and SA. Among those, seven variants show potentially deleterious features. Rs60029191 and a rare variant located in regulatory region of the HOMER1 gene may affect the promoter activities through interacting with predicted transcription factors. Two missense mutations existed in the SLC6A4 coding regions were firstly reported in Hong Kong Chinese MDD and SA patients, and both of them could affect the transport efficiency of SLC6A4 to serotonin. Moreover, a common variant rs6354 located in the untranslated region of this gene may affect the expression level or exonic splicing of serotonin transporter. In addition, both of a most studied polymorphism rs738499 and a low-frequency variant in the promoter region of the TEF gene were found to be located in potential transcription factor binding sites, which may let the two variants be able to influence the promoter activities of the gene. This study elucidated the potentially molecular mechanisms of the three candidate genes altering the risk for MDD and SA. These findings implied that not only common variants but rare variants could make contributions to the genetic susceptibility to MDD and SA in Chinese. Copyright © 2016 Elsevier B.V.

Despite the well-documented benefits of a physically active lifestyle, over 25% of American adults report that they never engage in regular recreational physical activity. Little is known about the determinants of physical activity among pregnant women. We investigated the predictors of physical activity in 386 normotensive pregnant women. Participants provided information about the type, frequency and duration of each physical activity performed during the first 20 weeks of pregnancy. We calculated odd ratios (OR) for active compared with inactive women using logistic regression models. Approximately 61% of women reported participating in some regular physical activity during pregnancy. Walking, swimming, gardening and jogging were the most common activities. Physical activity as an adolescent (OR 4.0) and during the year before pregnancy (OR 48.9) were the strongest predictors of physical activity in pregnancy. Active women who continued to exercise during pregnancy decreased the average intensity of their exercise and the weekly duration of exercise compared with the year before pregnancy. Nulliparas were twice as likely to engage in physical activity as compared with multiparas. Education and income were positively related with physical activity. Non-White women were 40-60% less likely to engage in physical activity as compared with White women. Smokers were also less likely to engage in physical activity. High protein intake was positively associated with physical activity, while the opposite was true for high carbohydrate intake. The identification of determinants of physical activity in pregnancy has important implications for developing strategies aimed at promoting a physically active lifestyle among young women.

Coronal Element Abundances of the Post-Common Envelope Binary V471 Tauri with ASCA

We report on ASCA observations of the coronally active companion star in the post-common envelope binary V471 Tau. While it would be prudent to check the following results with grating spectroscopy, we find that a single-temperature plasma model does not fit the data. Two temperature models with variable abundances indicate that Fe is underabundant compared to the Hyades photospheric mean, whereas, the high first ionization potential element Ne is overabundant. This is indicative of the inverse first ionization effect, believed to result from the fractionation of ionized material by the magnetic field in the upper atmosphere of the star. Evolutionary calculations indicate that there should be no peculiar abundances on the companion star resulting from the common envelope epoch. Indeed, we find no evidence for peculiar abundances, although uncertainties are high.

In vitro RPM fibrogenic potential assay of welding fumes.

The fibrogenic potential of 11 different welding fumes and metallic aerosols, considered to be reference standard surrogates for the commonly used welding technologies and applications responsible for 70% of welders exposure, is screened by using the rat peritoneal macrophage (RPM) in vitro bioassay. Only one class of fumes, that from the manual metal are welding of stainless steel, shows distinct fibrogenic potential. This fume, however, is not common to more than four or five of the heretofore 90 cases of pulmonary fibrosis reported among welders. Thus, although insoluble Cr(VI) is probably the active fibrogen in stainless steel fumes, an etiological factor common to all fibrogenic welding exposures must be sought; it is tentatively proposed to be NO chi, a potent experimental in vivo fibrogen copiously produced by certain welding processes and ubiquitous at low concentrations in the welding environment.

Interest and participation in global health activities among U.S. medical trainees has increased sharply in recent decades, yet the global health activities of physicians who have completed residency training remain understudied. Our objectives were to assess associations between individual characteristics and patterns of post-residency global health activities across the domains of health policy, education, and research. Cross-sectional, mixed methods national survey of 521 physicians with formal training in clinical and health services research and policy leadership. Main measures were post-residency global health activity and characteristics of this activity (location, funding, products, and perceived synergy with domestic activities). Most respondents (73%) hold faculty appointments across 84 U.S. medical schools and a strong plurality (46%) are trained in internal medicine. Nearly half of all respondents (44%) reported some global health activity after residency; however, the majority of this group (73%) reported spending ≤10% of professional time on global health in the past year. Among those active in global health, the majority (78%) reported receiving some funding for their global health activities, and most (83%) reported at least one scholarly, educational, or other product resulting from this work. Many respondents perceived synergies between domestic and global health activities, with 85% agreeing with the statement that their global health activities had enhanced the quality of their domestic work and increased their level of involvement with vulnerable populations, health policy advocacy, or research on the social determinants of health. Despite these perceived synergies, qualitative data from in-depth interviews revealed personal and institutional barriers to sustained global health involvement, including work-family balance and a lack of specific avenues for career development in global health. Post-residency global health activity is common in this diverse, multi-specialty group of physicians. Although those with global health experience describe synergies with their domestic work, the lack of established career development pathways may limit the benefits of this synergy for individuals and their institutions.

Periodic modulation of motor-unit activity in extrinsic hand muscles during multidigit grasping.

We recently examined the extent to which motor units of digit flexor muscles receive common input during multidigit grasping. This task elicited moderate to strong motor-unit synchrony (common input strength, CIS) across muscles (flexor digitorum profundus, FDP, and flexor pollicis longus, FPL) and across FDP muscle compartments, although the strength of this common input was not uniform across digit pairs. To further characterize the neural mechanisms underlying the control of multidigit grasping, we analyzed the relationship between firing of single motor units from these hand muscles in the frequency domain by computing coherence. We report three primary findings. First, in contrast to what has been reported in intrinsic hand muscles, motor units belonging to different muscles and muscle compartments of extrinsic digit flexors exhibited significant coherence in the 0- to 5- and 5- to 10-Hz frequency ranges and much weaker coherence in the higher 10-20 Hz range (maximum 0.0025 and 0.0008, respectively, pooled across all FDP compartment pairs). Second, the strength and incidence of coherence differed considerably across digit pairs. Third, contrary to what has been reported in the literature, across-muscle coherence can be stronger and more prevalent than within-muscle coherence, as FPL-FDP2 (thumb-index digit pair) exhibited the strongest and most prevalent coherence in our data (0.010 and 43% at 3 Hz, respectively). The heterogeneous organization of common input to these muscles and muscle compartments is discussed in relation to the functional role of individual digit pairs in the coordination of multiple digit forces in grasping.

A rare case of supraventricular tachycardia induced by Infliximab: a case report

PubMed Central

2009-01-01

Background Infliximab, a chimeric monoclonal immunoglobulin antibody to tumor necrosis factor-α, has been established as a safe and effective treatment of rheumatoid arthritis, active and fistulising crohn's disease. Infliximab is generally well tolerated drug. The commonly reported cardiac side effects of Infliximab include exacerbation of congestive heart failure, hypotension and syncope. Symptomatic disorders of cardiac rhythm have been reported only rarely in few case reports and to the best of our knowledge, no tachyarrhythmia has been reported in past. Case report We report the case of a supraventricular tachycardia that occurred within three hours of Infliximab infusion in a patient with rheumatoid arthritis. Conclusion It is interesting to note that prior infusions in this patient did not precipitate similar consequences, thus, emphasising the importance of careful monitoring of patients on Infliximab therapy for possible reactions, even if prior exposures have been uneventful.

Physical activity, sedentary and sleep behaviours have strong associations with health. This systematic review aimed to identify how clinical practice guidelines (CPGs) for the management of chronic obstructive pulmonary disease (COPD) report specific recommendations and strategies for these movement behaviours. A systematic search of databases (Medline, Scopus, CiNAHL, EMbase, Clinical Guideline), reference lists and websites identified current versions of CPGs published since 2005. Specific recommendations and strategies concerning physical activity, sedentary behaviour and sleep were extracted verbatim. The proportions of CPGs providing specific recommendations and strategies were reported. From 2370 citations identified, 35 CPGs were eligible for inclusion. Of these, 21 (60%) provided specific recommendations for physical activity, while none provided specific recommendations for sedentary behaviour or sleep. The most commonly suggested strategies to improve movement behaviours were encouragement from a healthcare provider (physical activity n = 20; sedentary behaviour n = 2) and referral for a diagnostic sleep study (sleep n = 4). Since optimal physical activity, sedentary behaviour and sleep durations and patterns are likely to be associated with mitigating the effects of COPD, as well as with general health and well-being, there is a need for further COPD-specific research, consensus and incorporation of recommendations and strategies into CPGs.

Objective Study the performance of a pediatric critical airway response team. Study Design Case series with chart review. Setting Freestanding academic children's hospital. Subjects and Methods A structured review of the electronic medical record was conducted for all activations of the critical airway team. Characteristics of the activations and patients are reported using descriptive statistics. Activation of the critical airway team occurred 196 times in 46 months (March 2012 to December 2015); complete data were available for 162 activations (83%). For 49 activations (30%), patients had diagnoses associated with difficult intubation; 45 (28%) had a history of difficult laryngoscopy. Results Activation occurred at least 4 times per month on average (vs 3 per month for hospital-wide codes). The most common reasons for team activation were anticipated difficult intubation (45%) or failed intubation attempt (20%). For 79% of activations, the team performed an airway procedure, most commonly direct laryngoscopy and tracheal intubation. Bronchoscopy was performed in 47% of activations. Surgical airway rescue was attempted 4 times. Cardiopulmonary resuscitation occurred in 41 activations (25%). Twenty-nine patients died during or following team activation (18%), including 10 deaths associated with the critical airway event. Conclusion Critical airway team activation occurred at least once per week on average. Direct laryngoscopy, tracheal intubation, and bronchoscopic procedures were performed frequently; surgical airway rescue was rare. Most patients had existing risk factors for difficult intubation. Given our rate of serious morbidity and mortality, primary prevention of critical airway events will be a focus of future efforts.

National plans are increasingly common but infrequently evaluated. The 2010 United States National Physical Activity Plan (NPAP) provided strategies to increase population levels of physical activity. This paper describes (i) the initial accomplishments of the NPAP sector teams, and (ii) results from a process evaluation to determine how the sectors operated, their cross-sector collaboration, challenges encountered, and positive experiences. During 2011, a quarterly reporting system was developed to capture sector-level activities. A year-end interview derived more detailed information. Interviews with 12 sector leads were recorded, transcribed verbatim, and analyzed for common themes. The 6 sectors worked on goals from the implementation plan that focused broadly on education, promotion, intervention, policy, collaboration, and evaluation. Through year-end interviews, themes were generated around operations, goal setting, and cross-sector collaboration. Challenges to the NPAP work included lack of funding and time, the need for marketing and promotion, and organizational support. Positive experiences included collaboration, efficiency of work, enhanced community dynamic, and accomplishments toward NPAP goals. These initial results on the NPAP sector teams can be used as a baseline assessment for future monitoring. The lessons learned may be useful to other practitioners developing evaluations around state- or national-level plans.

Background Obesity rates are rising in the United States, especially among low-income and racial/ethnic minority individuals. Exploring motivators and barriers relative to engaging in physical activity is imperative. Purpose The purpose of this study was to identify motivators and barriers relative to engagement in physical activity as reported by culturally diverse low-income adolescents and adults. Methods A total of 91 adolescent (11 to 15 years of age) and adult (18 years of age or older) participants who self-identified as African American, Hispanic, or non-Hispanic White engaged in age group-, race/ethnicity-, and gender-concordant focus groups. Results Qualitative data analysis indicated that the motivators and barriers most commonly identified among the adolescent and adult focus groups were: social influence; time and priorities; physical environment; fun and enjoyment; inherently physical activities; weight concerns; fatigue, physical discomfort and current fitness level; and immediate positive feelings. Discussion Findings were generally similar across age group, gender and race/ethnicity. Age group-specific, gender-specific and race/ethnicity-specific motivators and barriers were related to how commonly the motivators and barriers were identified among each group. Translation to Health Education Practice Implications for increasing physical activity among low-income culturally diverse adolescents and adults are discussed. PMID:29527247

Inhibition of proteases activity in intestine needs a sustainable acidic environment rather than a transient.

α-Chymotrypsin (α-CT) and trypsin are important components of the enzymatic barrier. They could degrade the therapeutic proteins and peptides, inhibit their activity consequently, and thereby reduce their oral bioavailability. Acidic agents, as one type of indirect protease inhibitors, have shown proof of concept in clinical trials. We report here the inactivated proteases due to acid influence can be reactivated immediately by environmental pH recovery regardless of how long the inactivation last. To keep the inactivation time of proteases for 4-5 h, we designed and prepared a sustained-release tablet containing citric acid (CA) which can effectively reduce the pH below 5.0 and maintain it for 5 h in the dissolution-reaction medium. The activity of α-CT and trypsin was quantified by analyzing the residual amount of their respective substrates BTEE and TAME. More than 80% of the substrates were survived in 5.0 h of incubation, whereas the common tablet inhibited the proteases activity for only two hours in the same experimental medium. It indicates that the sustained-release tablet loaded with CA can efficiently inhibit the α-CT and trypsin activity longer than the common tablet. The results will be beneficial for designing and formulating the peroral administration of peptide and protein drugs.

A minimal kinetic model for a viral DNA packaging machine.

Terminase enzymes are common to both eukaryotic and prokaryotic double-stranded DNA viruses. These enzymes possess ATPase and nuclease activities that work in concert to "package" a viral genome into an empty procapsid, and it is likely that terminase enzymes from disparate viruses utilize a common packaging mechanism. Bacteriophage lambda terminase possesses a site-specific nuclease activity, a so-called helicase activity, a DNA translocase activity, and multiple ATPase catalytic sites that function to package viral DNA. Allosteric interactions between the multiple catalytic sites have been reported. This study probes these catalytic interactions using enzyme kinetic, photoaffinity labeling, and vanadate inhibition studies. The ensemble of data forms the basis for a minimal kinetic model for lambda terminase. The model incorporates an ADP-driven conformational reorganization of the terminase subunits assembled on viral DNA, which is central to the activation of a catalytically competent packaging machine. The proposed model provides a unifying mechanism for allosteric interaction between the multiple catalytic sites of the holoenzyme and explains much of the kinetic data in the literature. Given that similar packaging mechanisms have been proposed for viruses as dissimilar as lambda and the herpes viruses, the model may find general utility in our global understanding of the enzymology of virus assembly.

Immunostimulants represent an emerging class of drugs for the treatment of infectious disorders and cancer. CpG oligonucleotides and imiquimod, prototypic drugs in this category, are now known to activate dendritic cells (DCs). Here we report the development of a highly sensitive, unbiased functional screen to detect DC-stimulatory signals. Because interleukin-1β (IL-1β) mRNA expression is closely associated with DC activation, we engineered DCs to stably express a fluorescent marker gene under the control of IL-1β promoter. By screening about 3000 compounds with the resulting DC biosensor clone, we identified DC-stimulatory potentials of topoisomerase I inhibitors (camptothecin derivatives) and microtubule depolymerizing drugs (colchicine and podophyllotoxin). In response to treatment with each agent, bone marrow–derived DC preparations exhibited characteristic phenotypic and/or functional changes associated with DC activation. All of these agents also triggered nuclear factor–κB (NFκB) activation in DCs, suggesting a common pharmacologic mechanism of action. Furthermore, locally administered colchicine induced in situ maturation and migration of DCs and augmented both humoral and cellular immune responses. These results support the practical utility of the DC-based biosensor system to discover novel DC-targeted immunostimulants and unveil previously unrecognized (and totally unexpected) pharmacologic activities of several drugs that are commonly used for the treatment of various disorders.

Bioelectrochemical systems (BESs) are promising technologies for energy and product recovery coupled with wastewater treatment, and the core microbial community in electrochemically active biofilm in BESs remains controversy. In the present study, 7 anodic communities from 6 bioelectrochemical systems in 4 labs in southeast, north and south-central of China are explored by 454 pyrosequencing. A total of 251,225 effective sequences are obtained for 7 electrochemically active biofilm samples at 3% cutoff level. While Alpha-, Beta-, and Gamma-proteobacteria are the most abundant classes (averaging 16.0–17.7%), Bacteroidia and Clostridia are the two sub-dominant and commonly shared classes. Six commonly shared genera i.e., Azospira, Azospirillum, Acinetobacter, Bacteroides, Geobacter, Pseudomonas, and Rhodopseudomonas dominate the electrochemically active communities and are defined as core genera. A total of 25 OTUs with average relative abundance >0.5% were selected and designated as core OTUs, and some species relating to these OTUs have been reported electrochemically active. Furthermore, cyclic voltammetry and chronoamperometry tests show that two strains from Acinetobacter guillouiae and Stappia indica, bacteria relate to two core OTUs, are electrochemically active. Using randomly selected bioelectrochemical systems, the study has presented extremely diverse bacterial communities in anodic biofilms, though, we still can suggest some potentially microbes for investigating the electrochemical mechanisms in bioelectrochemical systems.

We used quantitative, coordinate-based meta-analysis to objectively synthesize age-related commonalities and differences in brain activation patterns reported in 40 functional magnetic resonance imaging (fMRI) studies of reading in children and adults. Twenty fMRI studies with adults (age means: 23-34 years) were matched to 20 studies with children (age means: 7-12 years). The separate meta-analyses of these two sets showed a pattern of reading-related brain activation common to children and adults in left ventral occipito-temporal (OT), inferior frontal, and posterior parietal regions. The direct statistical comparison between the two meta-analytic maps of children and adults revealed higher convergence in studies with children in left superior temporal and bilateral supplementary motor regions. In contrast, higher convergence in studies with adults was identified in bilateral posterior OT/cerebellar and left dorsal precentral regions. The results are discussed in relation to current neuroanatomical models of reading and tentative functional interpretations of reading-related activation clusters in children and adults are provided. © 2015 Wiley Periodicals, Inc.

Common variable immunodeficiency (CVID) is characterised by repeated infection associated with primary acquired hypogammaglobulinemia. CVID frequently has a complex aetiology but, in certain cases, it has a monogenic cause. Recently, variants within the gene encoding the transcription factor STAT3 were implicated in monogenic CVID. Here, we describe a patient presenting with symptoms synonymous with CVID, who displayed reduced levels of IgG and IgA, repeated viral infections and multiple additional co-morbidities. Whole-exome sequencing revealed a de novo novel missense mutation in the coiled-coil domain of STAT3 (c.870A>T; p.K290N). Accordingly, the K290N variant of STAT3 was generated, and a STAT3 responsive dual-luciferase reporter assay revealed that the variant strongly enhances STAT3 transcriptional activity both under basal and stimulated (with IL-6) conditions. Overall, these data complement earlier studies in which CVID-associated STAT3 mutations are predicted to enhance transcriptional activity, suggesting that such patients may respond favourably to IL-6 receptor antagonists (e.g. tocilizumab).

Networking activities require time, work, and nurturing. The objective of this presentation is to share the experience gained from The Greenhouse gas Reduction through Agricultural Carbon Enhancement network (GRACEnet). GRACEnet, formally established in 2005 by the ARS/USDA, resulted from workshops, teleconferences, and other activities beginning in at least 2002. Critical factors for its formation were to develop and formalize a common vision, goals, and objectives, which was accomplished in a 2005 workshop. The 4-person steering committee (now 5) was charged with coordinating the part-time (0.05- to 0.5 SY/location) efforts across 30 ARS locations to develop four products; (1) a national database, (2) regional/national guidelines of management practices, (3) computer models, and (4) "state-of-knowledge" summary publications. All locations are asked to contribute to the database from their field studies. Communication with everyone and periodic meeting are extremely important. Required to populate the database has to be a common vision of sharing, format, and trust. Based upon the e-mail list, GRACEnet has expanded from about 30 to now nearly 70 participants. Annual reports and a new website help facilitate this activity.

Infection with Aphanomyces invadans, also known as epizootic ulcerative syndrome, is a destructive disease of freshwater and brackishwater fishes. Although more than 130 species of fish have been confirmed to be susceptible to this disease, some of the commercially important fish species like common carp, milk fish and tilapia are reported to be resistant. Species that are naturally resistant to a particular disease, provide a potential model to study the mechanisms of resistance against that disease. In the present study, following experimental infection with A. invadans in common carp Cyprinus carpio, sequential changes in various innate immune parameters and histopathological alterations were monitored. Some of the studied innate immunity parameters viz. respiratory burst, alternative complement and total antiproteases activities of the infected common carp were higher compared to control fish, particularly at early stages of infection. On the other hand, some parameters such as myeloperoxidase, lysozyme and alpha-2 macroglobulin activities were not altered. Histopathological examination of the muscle at the site of injection revealed well developed granulomas at 12 days post infection, with subsequent regeneration of muscle fibers. From the results, it could be inferred that innate defense mechanisms of common carp are able to neutralize the virulence factors secreted by A. invadans, thereby, preventing its invasive spread and containing the infection. The results obtained here will help to better understand the mechanisms underlying resistance against A. invadans infection. Copyright © 2015 Elsevier B.V. All rights reserved.

To provide data for physical activity assessment in practice by describing the leisure time activities of adolescents and determining if the activities and the metabolic equivalents (MET levels) of those activities differ for boys and girls. The study was conducted in five middle schools in three rural counties in North Carolina. Subjects were 1,211 6th, 7th, and 8th graders aged 11-14 (mean 12.2) years. Half (52.5%) were girls. The sample was 64% white, 24% African-American and 12% other races. The top five activities of boys were football, basketball, bicycling, running, and baseball; the top five activities of girls were talking, running, walking, bicycling, and dancing. The average MET was 5.3 for boys and 4.3 for girls (p = 0.000). By grade levels, 6th graders had an average MET of 4.9 and the MET of 8th graders was 4.5 (p < 0.05). Older youth, girls, and children of parents with more education reported significantly more sedentary activities than the other youth. Physical activity is an integral component of overall health. Once activities and activity levels are known, current practices can be augmented or changed to accommodate improved understanding of physical activity. Because an active lifestyle is important in preventing obesity and other chronic conditions and for general health, nurse practitioners (NPs) should ask adolescents about their common activities and encourage them to continue the more vigorous activities and reduce time spent in sedentary pursuits. Prescriptive physical activity can be included for primary, secondary, or even tertiary prevention, thus crossing all levels of NP practice.

The Vietnamese Ministry of Health introduced a legal regulation of clinical pharmacy services in December 2012. Objective To describe the services, and to explore reported barriers and facilitators in implementing clinical pharmacy activities in Vietnamese hospitals after the introduction of Vietnamese Ministry of Health legal regulation. Setting Thirty-nine hospitals in Hanoi, Vietnam, including 22 provincial and 17 district hospitals. Method A mixed methods study was utilized. An online questionnaire was sent to the hospitals. In-depth interviews were conducted with pairs of nominated pharmacists at ten of these hospitals. The questionnaire focused on four areas: facilities, workforce, policies and clinical pharmacy activities. Main outcome measure Proportion of clinical pharmacy activities in hospitals. Themes in clinical pharmacy practice. Results 34/39 (87%) hospitals had established clinical pharmacy teams. Most activities were non-patient-specific (87%) while the preliminary patient-specific clinical pharmacy services were available in only 8/39 hospitals (21%). The most common non-patient-specific activities were providing medicines information (97%), reporting adverse drug reactions (97%), monitoring medication usage (97%). The patient specific activities varied widely between hospitals and were ad hoc. The main challenges reported were: lack of workforce and qualified clinical pharmacists. Conclusion While most hospitals had hospital-based pharmacy activities, the direct patient care was limited. Training, education and an expanded work forces are needed to improve clinical pharmacy services.

The decoction and infusion of Rhoeo spathacea (Swartz) Stearn leaves have been recognized as a functional food particularly in South America, but has not yet gained international popularity as a beverage. The primary aim of this study was to establish the viability of R. spathacea aqueous leaf extracts as a beverage, in terms of its antioxidant activity and antibacterial activity. The antioxidant contents of aqueous and methanol leaf extracts were evaluated by the total phenolic content (TPC) and total flavonoid content (TFC) assays. The antioxidant activities measured were DPPH radical scavenging activity (FRS), ferric reducing power (FRP) and ferrous ion chelating (FIC) activity. The aqueous leaf extracts in the forms of decoction and infusion, were found to have comparable TPC and antioxidant activity with other herbal teas previously reported by our research group. Both decoction and infusion also exhibited antibacterial activity against six species of Gram positive and four species of Gram negative bacteria, notably methicillin-resistant Staphylococcus aureus and Neisseria gonorrhoeae. A total of four different known phenolic compounds were identified by HPLC and MS, three of which have not been previously reported to be found in this plant. Both the decoction and infusion of the leaves R. spathacea have potential to be popularized into a common beverage.

In Australia, people who inject drugs (PWID) commonly report the use of benzodiazepines (BZDs). This paper explores the emerging use of alprazolam among PWID in Melbourne, Australia. This study reports on 3 years of data collected through the Victorian Illicit Drug Reporting System (2008-2010). Structured interviews were conducted with 451 PWID and analysed using odds ratios and χ(2)-tests for trends over time. While the proportion of PWID reporting recent BZD use remained stable over time, the proportion reporting alprazolam to be their most commonly used BZD fluctuated, peaking in 2009. Alprazolam users were significantly more likely to report using illicit BZDs and to report recent BZD injection compared with users of other BZDs. Alprazolam use was associated with the sale of drugs for cash, but not with other criminal activities. The fluctuations in alprazolam use over time may be reflective of medical practitioners ceasing to prescribe alprazolam in response to reports of associated harms; however, this may in turn be driving the illicit alprazolam market. While the data do not indicate a clear association between alprazolam use and harms, considering the potential severity of associated harms and the association between alprazolam use and anterograde amnesia, patterns of alprazolam use among PWID should be closely monitored. Potential changes to prescribing practice should consider unintended consequences, such as replacement with other BZD types, or illicitly obtained BZDs. © 2011 Australasian Professional Society on Alcohol and other Drugs.

Blastocystis spp. is a common enteric stramenopile parasite that colonizes the colon of hosts of a diverse array of species, including humans. It has been shown to compromise intestinal epithelial cell barrier integrity and mediate the production of pro-inflammatory cytokines and chemokines. Mucosal epithelial surfaces, including the intestinal epithelium, are increasingly recognized to perform a vital surveillance role in the context of innate immunity, through the expression of pathogen recognition receptors, such as Toll-like receptors (TLRs). In this study, we use the human TLR reporter monocytic cell line, THP1-Blue, which expresses all human TLRs, to investigate effects of Blastocystis on TLR activation, more specifically the activation of TLR-2, -4 and -5. We have observed that live Blastocystis spp. parasites and whole cell lysate (WCL) alone do not activate TLRs in THP1-Blue. Live ST4-WR1 parasites inhibited LPS-mediated NF-κB activation in THP1-Blue. In contrast, ST7-B WCL and ST4-WR1 WCL induced pleiotropic modulation of ligand-specific TLR-2 and TLR-4 activation, with no significant effects on flagellin-mediated TLR-5 activation. Real time-qPCR analysis on SEAP reporter gene confirmed the augmenting effect of ST7-B on LPS-mediated NF-κB activation in THP1-Blue. Taken together, this is the first study to characterize interactions between Blastocystis spp. and host TLR activation using an in vitro reporter model. PMID:24551212

Anabolic androgenic steroids (AAS) are a class of steroid hormones related to the male hormone testosterone. They are frequently detected as drugs in sport doping control. Being similar to or derived from natural male hormones, AAS share the activation of the androgen receptor (AR) as common mechanism of action. The mammalian androgen responsive reporter gene assay (AR CALUX bioassay), measuring compounds interacting with the AR can be used for the analysis of AAS without the necessity of knowing their chemical structure beforehand, whereas current chemical-analytical approaches may have difficulty in detecting compounds with unknown structures, such as designer steroids. This study demonstrated that AAS prohibited in sports and potential designer AAS can be detected with this AR reporter gene assay, but that also additional steroid activities of AAS could be found using additional mammalian bioassays for other types of steroid hormones. Mixtures of AAS were found to behave additively in the AR reporter gene assay showing that it is possible to use this method for complex mixtures as are found in doping control samples, including mixtures that are a result of multi drug use. To test if mammalian reporter gene assays could be used for the detection of AAS in urine samples, background steroidal activities were measured. AAS-spiked urine samples, mimicking doping positive samples, showed significantly higher androgenic activities than unspiked samples. GC-MS analysis of endogenous androgens and AR reporter gene assay analysis of urine samples showed how a combined chemical-analytical and bioassay approach can be used to identify samples containing AAS. The results indicate that the AR reporter gene assay, in addition to chemical-analytical methods, can be a valuable tool for the analysis of AAS for doping control purposes.

Urinary incontinence is one of the most commonly reported and distressing side effects of radical prostatectomy for prostate carcinoma. Several studies have suggested that symptoms may be worse in obese men but to our knowledge no research has addressed the joint effects of obesity and a sedentary lifestyle. We evaluated the association of obesity and lack of physical activity with urinary incontinence in a sample of men who had undergone radical prostatectomy. Height and weight were abstracted from charts, and obesity was defined as body mass index 30 kg/m(2) or greater. Men completed a questionnaire before surgery that included self-report of vigorous physical activity. Men who reported 1 hour or more per week of vigorous activities were considered physically active. Men reported their incontinence to the surgeon at their urology visits. Information on incontinence was abstracted from charts at 6 and 58 weeks after surgery. At 6 weeks after surgery 59% (405) of men were incontinent, defined as any pad use. At 58 weeks after surgery 22% (165) of men were incontinent. At 58 weeks incontinence was more prevalent in men who were obese and physically inactive (59% incontinent). Physical activity may offset some of the negative consequences of being obese because the prevalence of incontinence at 58 weeks was similar in the obese and active (25% incontinent), and nonbese and inactive (24% incontinent) men. The best outcomes were in men who were nonobese and physically active (16% incontinent). Men who were not obese and were active were 26% less likely to be incontinent than men who were obese and inactive (RR 0.74, 95% CI 0.52-1.06). Pre-prostatectomy physical activity and obesity may be important factors in post-prostatectomy continence levels. Interventions aimed at increasing physical activity and decreasing weight in patients with prostate cancer may improve quality of life by offsetting the negative side effects of treatment.

Online Social Engagement by Cancer Patients: A Clinic-Based Patient Survey

PubMed Central

Wallner, Lauren

2016-01-01

Background The Internet is commonly used as a source of health information, but little is known about the Internet practices specific to cancer patients. Objective To understand cancer patients’ use of the Internet as an informational resource and for social support. Methods The researchers conducted a survey of 1282 patients at a comprehensive cancer center to assess frequency of Internet access and online behaviors. Results Of the cancer patients surveyed, 1096 (85.49%) had Internet access; of those with Internet access, 953 (86.95%) reported going online at least weekly, and 747 (68.16%) reported daily online activity. Grouping Internet users by their level of online social engagement revealed that out of 1096 users, 331 (30.20%) had not sought out social connections online, 227 (20.71%) had read about experiences from other cancer patients, 410 (37.41%) had also written about their personal experiences, and 128 (11.68%) had participated in a formal online group for cancer patients. Increased online social engagement was associated with an increased perception that the Internet was useful for social support. Conclusions Internet use among cancer patients was common, and most patients reported that they found useful information about their cancer diagnosis online. Cancer patients who actively posted or shared content perceived more social support from the Internet than those who used the Internet solely as an informational resource or to read about other cancer patients’ experiences. Physicians have a great opportunity to direct users to quality health information on the Web. PMID:28410186

Muscle activation in the loaded free barbell squat: a brief review.

Clark, Dave R; Lambert, Mike I; Hunter, Angus M

2012-04-01

The purpose of this article was to review a series of studies (n = 18) where muscle activation in the free barbell back squat was measured and discussed. The loaded barbell squat is widely used and central to many strength training programs. It is a functional and safe exercise that is obviously transferable to many movements in sports and life. Hence, a large and growing body of research has been published on various aspects of the squat. Training studies have measured the impact of barbell squat loading schemes on selected training adaptations including maximal strength and power changes in the squat. Squat exercise training adaptations and their impact on a variety of performance parameters, in particular countermovement jump, acceleration, and running speed, have also been reported. Furthermore, studies have reported on the muscle activation of the lower limb resulting from variations of squat depth, foot placement, training status, and training intensity. There have also been studies on the impact of squatting with or without a weight belt on trunk muscle activation (TMA). More recently, studies have reported on the effect of instability on TMA and squat performance. Research has also shown that muscle activation of the prime movers in the squat exercise increases with an increase in the external load. Also common variations such as stance width, hip rotation, and front squat do not significantly affect muscle activation. However, despite many studies, this information has not been consolidated, resulting in a lack of consensus about how the information can be applied. Therefore, the purpose of this review was to examine studies that reported muscle activation measured by electromyography in the free barbell back squat with the goal of clarifying the understanding of how the exercise can be applied.

Uganda is experiencing a dual burden of over- and undernutrition, with overweight prevalence increasing while underweight remains common. Potential weight-related factors, particularly physical activity, sleep, and rural/urban status, are not currently well understood or commonly assessed in Ugandan youth. The purpose of this study was to pilot test a survey measuring weight-related factors in rural and urban Ugandan schoolchildren. A cross-sectional survey measured sociodemographics, physical activity, sleep patterns, and dietary factors in 148 rural and urban schoolchildren aged 11-16 in central Uganda. Height and weight were objectively measured. Rural and urban youth were compared on these factors using χ 2 and t tests. Regression was used to identify correlates of higher body mass index (BMI) percentile in the full sample and nonstunted youth. Youth were on average 12.1 ± 1.1 years old; underweight (10%) was more common than overweight (1.4%). Self-reported sleep duration and subjective sleep quality did not differ by rural/urban residence. Rural children overall had higher BMI percentile and marginally higher stunting prevalence. In adjusted analyses in both the full and nonstunted samples, higher BMI percentile was related to living in a rural area, higher frequency of physical activity, and higher subjective sleep quality; it was negatively related to being active on weekends. In the full sample, higher BMI percentile was also related to female gender, whereas in nonstunted youth, higher BMI was related to age. BMI percentile was unrelated to sedentary time, performance of active chores and sports, and dietary factors. This study is one of the first to pilot test a survey assessing weight-related factors, particularly physical activity and sleep, in Ugandan schoolchildren. BMI percentile was related to several sociodemographic, sleep, and physical activity factors among primarily normal-weight school children in Uganda, providing a basis for understanding weight status in the context of the nutrition transition.

The aim of this study was to investigate the leisure and recreational activities of a cohort of 34 students attending a full-time special school as reported by the students and their parents. Leisure activities which were mostly solitary and passive in nature were identified as those being most commonly engaged in. Barriers to leisure were also identified, with 'access to' and 'location of' the leisure facilities being barriers perceived by both students and parents. Data on aspects of leisure use, e.g. enjoyment, participation, assistance required, socialization and choice, were also collected.

Activity of benzimidazoles against Dientamoeba fragilis (Trichomonadida, Monocercomonadidae) in vitro and correlation of beta-tubulin sequences as an indicator of resistance.

Recently, Dientamoeba fragilis has emerged as a significant and common enteropathogen. The majority of patients with dientamoebiasis present with gastrointestinal complaints and chronic symptoms are common. Numerous studies have successfully demonstrated parasite clearance, coupled with complete resolution of clinical symptoms following treatment with various antiparasitic compounds. Despite this, there is very little in vitro susceptibility data available for the organism. Benzimidazoles are a class of antiparasitic drugs that are commonly used for the treatment of protozoan and helminthic infections. Susceptibility testing was undertaken on four D. fragilis clinical isolates against the following benzimidazoles: albendazole, flubendazole, mebendazole, nocodazole, triclabendazole and thiabendazole. The activities of the antiprotozoal compounds at concentrations ranging from 2 μg/mL to 500 μg/mL were determined via cell counts of D. fragilis grown in xenic culture. All tested drugs showed no efficacy. The beta-tubulin transcript was sequenced from two of the D. fragilis isolates and amino acid sequences predicted a susceptibility to benzimidazoles. This is the first study to report susceptibility profiles for benzimidazoles against D. fragilis, all of which were not active against the organism. This study also found that beta-tubulin sequences cannot be used as a reliable marker for resistance of benzimidazoles in D. fragilis. D. Stark et al., published by EDP Sciences, 2014

E-selectin engages PSGL-1 and CD44 through a common signaling pathway to induce integrin alphaLbeta2-mediated slow leukocyte rolling.

In inflamed venules, neutrophils rolling on E-selectin induce integrin alpha(L)beta(2)-dependent slow rolling on intercellular adhesion molecule-1 by activating Src family kinases (SFKs), DAP12 and Fc receptor-gamma (FcRgamma), spleen tyrosine kinase (Syk), and p38. E-selectin signaling cooperates with chemokine signaling to recruit neutrophils into tissues. Previous studies identified P-selectin glycoprotein ligand-1 (PSGL-1) as the essential E-selectin ligand and Fgr as the only SFK that initiate signaling to slow rolling. In contrast, we found that E-selectin engagement of PSGL-1 or CD44 triggered slow rolling through a common, lipid raft-dependent pathway that used the SFKs Hck and Lyn as well as Fgr. We identified the Tec kinase Bruton tyrosine kinase as a key signaling intermediate between Syk and p38. E-selectin engagement of PSGL-1 was dependent on its cytoplasmic domain to activate SFKs and slow rolling. Although recruiting phosphoinositide-3-kinase to the PSGL-1 cytoplasmic domain was reported to activate integrins, E-selectin-mediated slow rolling did not require phosphoinositide-3-kinase. Studies in mice confirmed the physiologic significance of these events for neutrophil slow rolling and recruitment during inflammation. Thus, E-selectin triggers common signals through distinct neutrophil glycoproteins to induce alpha(L)beta(2)-dependent slow rolling.

1998-07-01

The Freehand System, an eight-channel functional electrical stimulation (FES) system, was implanted in five adolescents with C-5 or C-6 tetraplegia to provide stimulated lateral pinch and palmar grasp. Following completion of inpatient training on how to use the Freehand System for predefined and self-selected activities of daily living (ADL), the adolescents were discharged to use their Freehand systems at home and school. A telephone survey was administered on a weekly basis to obtain information on the type of ADL performed with the Freehand System, reasons for not using the Freehand System, and perceived barriers and motivators to FES use. Twenty surveys were obtained on each adolescent, resulting in a total of 100 surveys. The most common type of activity performed with the Freehand System was self-care, which included tasks such as eating, grooming, and brushing teeth. The Freehand System was also used for productivity activities defined as writing, socialization, and manipulation of school and household objects. Motivators to Freehand System use included perceived need and importance to perform an ADL in an independent fashion, physical ease of using the Freehand System, and availability of social supports that facilitated Freehand System use. While there were several reported barriers to Freehand System use, incompatibility with multiple transfers to and from the wheelchair and lack of physical assistance during morning care to don the system were perceived as two of the more common reasons for nonuse.

Zika Virus: Common Questions and Answers.

Since local mosquito-borne transmission of Zika virus was first reported in Brazil in early 2015, the virus has spread rapidly, with active transmission reported in at least 61 countries and territories worldwide, including the United States. Zika virus infection during pregnancy is a cause of microcephaly and other severe brain anomalies. The virus is transmitted primarily through the bite of an infected Aedes mosquito, but other routes of transmission include sexual, mother-to-fetus during pregnancy, mother-to-infant at delivery, laboratory exposure, and, possibly, transfusion of blood products. Most persons with Zika virus infection are asymptomatic or have only mild symptoms; hospitalizations and deaths are rare. When symptoms are present, maculopapular rash, fever, arthralgia, and conjunctivitis are most common. Zika virus testing is recommended for persons with possible exposure (those who have traveled to or live in an area with active transmission, or persons who had sex without a condom with a person with possible exposure) if they have symptoms consistent with Zika virus disease. Testing is also recommended for pregnant women with possible exposure, regardless of whether symptoms are present. Treatment is supportive, and no vaccine is currently available. The primary methods of prevention include avoiding bites of infected Aedes mosquitoes and reducing the risk of sexual transmission. Pregnant women should not travel to areas with active Zika virus transmission, and men and women who are planning to conceive in the near future should consider avoiding nonessential travel to these areas. Condoms can reduce the risk of sexual transmission.

The aim of this study is to compare the generic and ostomy-specific quality of life (QoL) between cancer and non-cancer ostomy patients using a mixed-method design. All patients with an ostomy participating in the Stomapanel of the Dutch Ostomy Association were asked to complete a generic (RAND-36) and ostomy-specific (Stoma-QoL) QoL questionnaire. In addition, open-ended questions on symptoms, restrictions or adaptations influencing daily life were included. The generic and ostomy-specific QoL between cancer and non-cancer ostomy patients were compared using linear regression analyses. Qualitative responses were analysed using content analysis. In total, 668 patients were included: 379 cancer patients (80 % colorectal, 17 % bladder and 3 % other) and 289 non-cancer patients (38 % colitis ulcerosa, 22 % Crohn's disease and 40 % other) with a colostomy (55 %), ileostomy (31 %) and/or urostomy (16 %). Adjusted for gender, age, type of ostomy and time elapsed since ostomy surgery, cancer ostomy patients scored higher (better) on Stoma-QoL (β = 2.1) and all RAND-36 domains (9.1 < β ≤ 19.5) except on mental health compared to non-cancer ostomy patients. Of the 33 themes coded for in the content analysis, fatigue or sleeplessness, leakages, pain, bladder or bowel complaints, physical functioning or activity, travelling or being away from home, other daily activities (including work), clothing and diet were among the 10 most frequently reported themes, although ranking differed between both patient groups. Besides, cancer ostomy patients frequently reported on the impact on (engaging in a) relationship or sexual intimacy and non-cancer ostomy patients frequently reported to be relieved of symptoms and restrictions in daily life. Cancer patients reported better generic and ostomy-specific QoL than non-cancer ostomy patients. In both cancer and non-cancer ostomy patients, fatigue or sleeplessness, leakages, pain, bladder or bowel complaints, physical functioning or activity, travelling or being away from home, other daily activities (including work), clothing and diet were among the 10 most common reported themes influencing daily life. However, the ranking of these 10 most common themes was different in both patient groups.

Lim, Kai Zheong; Ghosh, Peter; Goldschlager, Tony

2018-01-01

Background Lumbar microdiscectomy is the most commonly performed spine surgery procedure. Over time it has evolved to a minimally invasive procedure. Traditionally patients were advised to restrict activity following lumbar spine surgery. However, post-operative instructions are heterogeneous. The purpose of this report is to assess, by survey, the perioperative care practices of Australasian neurosurgeons in the minimally invasive era. Methods A survey was conducted by email invitation sent to all full members of the Neurosurgical Society of Australasia (NSA). This consisted of 11 multi-choice questions relating to operative indications, technique, and post-operative instructions for lumbar microdiscectomy answered by an electronically distributed anonymized online survey. Results The survey was sent to all Australasian Neurosurgeons. In total, 68 complete responses were received (28.9%). Most surgeons reported they would consider a period of either 4 to 8 weeks (42.7%) or 8 to 12 weeks (32.4%) as the minimum duration of radicular pain adequate to offer surgery. Unilateral muscle dissection with unilateral discectomy was practiced by 76.5%. Operative microscopy was the most commonly employed method of magnification (76.5%). The majority (55.9%) always refer patients to undergo inpatient physiotherapy. Sitting restrictions were advised by 38.3%. Lifting restrictions were advised by 83.8%. Conclusions Australasian neurosurgical lumbar microdiscectomy perioperative care practices are generally consistent with international practices and demonstrate a similar degree of heterogeneity. Recommendation of post-operative activity restrictions by Australasian neurosurgeons is still common. This suggests a role for the investigation of the necessity of such restrictions in the era of minimally invasive spine surgery. PMID:29732417

Measuring Physical Activity in a Cardiac Rehabilitation Population Using a Smartphone-Based Questionnaire

2013-01-01

Background Questionnaires are commonly used to assess physical activity in large population-based studies because of their low cost and convenience. Many self-report physical activity questionnaires have been shown to be valid and reliable measures, but they are subject to measurement errors and misreporting, often due to lengthy recall periods. Mobile phones offer a novel approach to measure self-reported physical activity on a daily basis and offer real-time data collection with the potential to enhance recall. Objective The aims of this study were to determine the convergent validity of a mobile phone physical activity (MobilePAL) questionnaire against accelerometry in people with cardiovascular disease (CVD), and to compare how the MobilePAL questionnaire performed compared with the commonly used self-recall International Physical Activity Questionnaire (IPAQ). Methods Thirty adults aged 49 to 85 years with CVD were recruited from a local exercise-based cardiac rehabilitation clinic in Auckland, New Zealand. All participants completed a demographics questionnaire and underwent a 6-minute walk test at the first visit. Subsequently, participants were temporarily provided a smartphone (with the MobilePAL questionnaire preloaded that asked 2 questions daily) and an accelerometer, which was to be worn for 7 days. After 1 week, a follow-up visit was completed during which the smartphone and accelerometer were returned, and participants completed the IPAQ. Results Average daily physical activity level measured using the MobilePAL questionnaire showed moderate correlation (r=.45; P=.01) with daily activity counts per minute (Acc_CPM) and estimated metabolic equivalents (MET) (r=.45; P=.01) measured using the accelerometer. Both MobilePAL (beta=.42; P=.008) and age (beta=–.48, P=.002) were significantly associated with Acc_CPM (adjusted R2=.40). When IPAQ-derived energy expenditure, measured in MET-minutes per week (IPAQ_met), was considered in the predicted model, both IPAQ_met (beta=.51; P=.001) and age (beta=–.36; P=.016) made unique contributions (adjusted R2=.47, F 2,27=13.58; P<.001).There was also a significant association between the MobilePAL and IPAQ measures (r=.49, beta=.51; P=.007). Conclusions A mobile phone–delivered questionnaire is a relatively reliable and valid measure of physical activity in a CVD cohort. Reliability and validity measures in the present study are comparable to existing self-report measures. Given their ubiquitous use, mobile phones may be an effective method for physical activity surveillance data collection. PMID:23524251

EthA, a Common Activator of Thiocarbamide-Containing Drugs Acting on Different Mycobacterial Targets▿

Many of the current antimycobacterial agents require some form of cellular activation unmasking reactive groups, which in turn will bind to their specific targets. Therefore, understanding the mechanisms of activation of current antimycobacterials not only helps to decipher mechanisms of drug resistance but may also facilitate the development of alternative activation strategies or of analogues that do not require such processes. Herein, through the use of genetically defined strains of Mycobacterium bovis BCG we provide evidence that EthA, previously shown to activate ethionamide, also converts isoxyl (ISO) and thiacetazone (TAC) into reactive species. These results were further supported by the development of an in vitro assay using purified recombinant EthA, which allowed direct assessment of the metabolism of ISO. Interestingly, biochemical analysis of [14C]acetate-labeled cultures suggested that all of these EthA-activated drugs inhibit mycolic acid biosynthesis via different mechanisms through binding to specific targets. This report is also the first description of the molecular mechanism of action of TAC, a thiosemicarbazone antimicrobial agent that is still used in the treatment of tuberculosis as a second-line drug in many developing countries. Altogether, the results suggest that EthA is a common activator of thiocarbamide-containing drugs. The broad specificity of EthA can now be used to improve the activation process of these drugs, which may help overcome the toxicity problems associated with clinical thiocarbamide use.

Study of child-raising issues published in newspapers is lacking. The purpose of this article is to determine the spectrum of issues associated with child raising based on a newspaper. We conducted a cross-sectional study of items related to children (aged <19 years) reported in a Japanese newspaper from July 1, 2001, to June 30, 2002. A total of 1287 child-related items were published. The percentages of reports regarding individual health, health-related issues, topics on two or more issues, and global child issues were 5.9%, 28.8%, 62.9%, and 2.4%, respectively. The most common singly reported issues from 446 items were on child play and recreation, welfare activities, security, child abuse, child death, sports, and parenting. These reports assist parents, families, nurses, pediatricians, and child care workers in providing information on healthy child raising.

ABCB1 (adenosine triphosphate-binding cassette transporter B1) mediates cellular elimination of many chemotherapeutic agents including paclitaxel, which is commonly used to treat ovarian cancer. A significant association between common single nucleotide polymorphisms (SNPs) in ABCB1 and progression-free survival has been reported in patients with ovarian cancer. Variable paclitaxel clearance due to genotype specific differences in ABCB1 activity in cancer cells and/or normal tissues may underlie the association. Using cell-based models, we evaluated the correlations between ABCB1 expression, polymorphisms, transporter activity and paclitaxel sensitivity in ovarian cancer (n = 10) and lymphoblastoid (n = 19) cell lines. Close associations between ABCB1 expression, transporter function and paclitaxel sensitivity were found in lymphoblastoid cell lines, although we could not demonstrate an association with common SNPs. In ovarian cancer cell lines, ABCB1 expression was low and the association between expression and function was lost. These results suggest that ABCB1 related survival difference in ovarian cancer patients is more likely to be due to differential whole body paclitaxel clearance mediated by normal cells rather than a direct effect on cancer cells.

Background Gastroesophageal reflux disease (GERD) is a common cause of discomfort and morbidity worldwide. However, information on determinants of GERD from large-scale studies in low- to medium-income countries is limited. We investigated the factors associated with different measures of GERD symptoms, including frequency, patient-perceived severity, and onset time. Methods We performed a cross-sectional analysis of the baseline data from a population-based cohort study of ∼50,000 individuals in in Golestan Province, Iran. GERD symptoms in this study included regurgitation and/or heartburn. Results Approximately 20% of participants reported at least weekly symptoms. Daily symptoms were less commonly reported by men, those of Turkmen ethnicity, and nass chewers. On the other hand, age, body mass index, alcohol drinking, cigarette smoking, opium use, lower socioeconomic status, and lower physical activity were associated with daily symptoms. Most of these factors showed similar associations with severe symptoms. Women with higher BMI and waist to hip ratio were more likely to report frequent and severe GERD symptoms. Hookah smoking (OR 1.34, 95% CI 1.02–1.75) and opium use (OR 1.70, 95% CI 1.55–1.87) were associated with severe symptoms, whereas nass chewing had an inverse association (OR 0.87, 95% CI 0.76–0.99). After exclusion of cigarette smokers, hookah smoking was still positively associated and nass chewing was inversely associated with GERD symptoms (all frequencies combined). Conclusion GERD is common in this population. The associations of hookah and opium use and inverse association of nass use with GERD symptoms are reported for the first time. Further studies are required to investigate the nature of these associations. Other determinants of GERD were mostly comparable to those reported elsewhere. PMID:24586635

Context In response to national efforts to improve quality of care, policymakers and health care leaders have increasingly turned to quality improvement collaboratives (QICs) as an efficient approach to improving provider practices and patient outcomes through the dissemination of evidence-based practices. This article presents findings from a systematic review of the literature on QICs, focusing on the identification of common components of QICs in health care and exploring, when possible, relations between QIC components and outcomes at the patient or provider level. Methods A systematic search of five major health care databases generated 294 unique articles, twenty-four of which met our criteria for inclusion in our final analysis. These articles pertained to either randomized controlled trials or quasi-experimental studies with comparison groups, and they reported the findings from twenty different studies of QICs in health care. We coded the articles to identify the components reported for each collaborative. Findings We found fourteen crosscutting components as common ingredients in health care QICs (e.g., in-person learning sessions, phone meetings, data reporting, leadership involvement, and training in QI methods). The collaboratives reported included, on average, six to seven of these components. The most common were in-person learning sessions, plan-do-study-act (PDSA) cycles, multidisciplinary QI teams, and data collection for QI. The outcomes data from these studies indicate the greatest impact of QICs at the provider level; patient-level findings were less robust. Conclusions Reporting on specific components of the collaborative was imprecise across articles, rendering it impossible to identify active QIC ingredients linked to improved care. Although QICs appear to have some promise in improving the process of care, there is great need for further controlled research examining the core components of these collaboratives related to patient- and provider-level outcomes.

Recent reports indicate that vibrator use during solo and partnered sexual activities is common among heterosexual men and women in the United States. However, little research has comprehensively assessed vibrator use among gay and bisexually identified men. This study sought to document the extent to which gay and bisexually identified men report using vibrators, the sexual and relational situations within which they use them, and how men use vibrators on their own and their partners' bodies. Data were collected from 25,294 gay and bisexually identified men from 50 U.S. states and from the District of Columbia via an internet-based survey. Measures included sociodemographics, health-related indicators, sexual behaviors, and those related to recent and past use of vibrators during solo and partnered sexual interactions with other men. Approximately half (49.8%) of gay and bisexually identified men reported having used vibrators. Most men who had used a vibrator in the past reported use during masturbation (86.2%). When used during partnered interactions, vibrators were incorporated into foreplay (65.9%) and intercourse (59.4%). Men reported frequent insertion of vibrators into the anus or rectum when using them during masturbation (87.3%), which was also common during partnered interactions (∼60%), but varied slightly for casual and relationship sex partners. For both masturbation and partnered interactions, men overwhelmingly endorsed the extent to which vibrator use contributed to sexual arousal, orgasm, and pleasure. Vibrator use during both solo and partnered sexual acts was common among the gay and bisexually identified men in this sample and was described by men as adding to the quality of their sexual experiences. © 2010 International Society for Sexual Medicine.

The field of foot and ankle surgery lacks a widely accepted gold-standard patient-reported outcome instrument. With the changing infrastructure of the medical profession, more efficient patient-reported outcome tools are needed to reduce respondent burden and increase participation while providing consistent and reliable measurement across multiple pathologies and disciplines. The primary purpose of the present study was to validate 3 Patient-Reported Outcomes Measurement Information System computer adaptive tests (CATs) most relevant to the foot and ankle discipline against the Foot and Ankle Outcome Score (FAOS) and the Short Form 12 general health status survey in patients with 6 common foot and ankle pathologies. Patients (n = 240) indicated for operative treatment for 1 of 6 common foot and ankle pathologies completed the CATs, FAOS, and Short Form 12 at their preoperative surgical visits, 1 week subsequently (before surgery), and at 6 months postoperatively. The psychometric properties of the instruments were assessed and compared. The Patient-Reported Outcomes Measurement Information System CATs each took less than 1 minute to complete, whereas the FAOS took 6.5 minutes, and the Short Form 12 took 3 minutes. CAT scores were more normally distributed and had fewer floor and ceiling effects than those on the FAOS, which reached as high as 24%. The CATs were more precise than the FAOS and had similar responsiveness and test-retest reliability. The physical function and mobility CATs correlated strongly with the activities subscale of the FAOS, and the pain interference CAT correlated strongly with the pain subscale of the FAOS. The CATs and FAOS were responsive to changes with operative treatment for 6 common foot and ankle pathologies. The CATs performed as well as or better than the FAOS in all aspects of psychometric validity. The Patient-Reported Outcomes Measurement Information System CATs show tremendous potential for improving the study of patient outcomes in foot and ankle research through improved precision and reduced respondent burden.

Seborrheic dermatitis is a common inflammatory skin disease, affecting between 1% and 3% of immunocompetent adults. While its cause is unknown, a number of predisposing factors have been reported, including the implications of Malassezia yeasts. Various treatment options are available, such as ciclopirox shampoo, which combines anti-Malassezia activity with an anti-inflammatory action. This agent has been shown to be an effective and safe treatment for seborrheic dermatitis of the scalp.

Despite the known benefits of physical activity, very few people, especially women, are found to engage in regular physical activity. This study explored the perceptions, barriers and facilitators related to physical activity among women in Thiruvananthapuram City, India. Four focus group discussions were conducted among individuals between 25 and 60 years of age, in a few areas of Thiruvananthapuram City Corporation limits in Kerala, preparatory to the design of a physical activity intervention trial. An open-ended approach was used and emergent findings were analyzed and interpreted. Women associated physical activity mostly with household activities. The majority of the women considered their activity level adequate, although they engaged in what the researchers concluded were quite low levels of activity. Commonly reported barriers were lack of time, motivation, and interest; stray dogs; narrow roads; and not being used to the culture of walking. Facilitators of activity were seeing others walking, walking in pairs, and pleasant walking routes. Walking was reported as the most feasible physical activity by women. Physical activity promotion strategies among women should address the prevailing cultural norms in the community, and involve social norming and overcoming cultural barriers. They should also target the modifiable determinants of physical activity, such as improving self-efficacy, improving knowledge on the adequacy of physical activity and its recommendations, facilitating goal-setting, and enhancing social support through peer support and group-based activities. © The Author(s) 2015.

Autotaxin (ATX) is a secreted enzyme responsible for the hydrolysis of lysophosphatidylcholine (LPC) to the bioactive lysophosphatidic acid (LPA) and choline. The ATX-LPA signaling pathway is implicated in cell survival, migration, and proliferation; thus, the inhibition of ATX is a recognized therapeutic target for a number of diseases including fibrotic diseases, cancer, and inflammation, among others. Many of the developed synthetic inhibitors for ATX have resembled the lipid chemotype of the native ligand; however, a small number of inhibitors have been described that deviate from this common scaffold. Herein, we report the structure-activity relationships (SAR) of a previously reported small molecule ATX inhibitor. We show through enzyme kinetics studies that analogues of this chemotype are noncompetitive inhibitors, and by using a crystal structure with ATX we confirm the discrete binding mode.

Calculating the Velocity in the Moss

The velocity of the warm (1 MK) plasma in the footpoint of the hot coronal loops (commonly called moss) could help discriminate between different heating frequencies in the active region core. Strong velocities would indicated low-frequency heating, while velocities close to zero would indicate high-frequency heating. Previous results have found disparaging observations, with both strong velocities and velocities close to zero reported. Previous results are based on observations from Hinode/EIS. The wavelength arrays for EIS spectra are typically calculated by assuming quiet Sun velocities are zero. In this poster, we determine the velocity in the moss using observations with SoHO/SUMER. We rely on neutral or singly ionized spectral lines to determine accurately the wavelength array associated with the spectra. SUMER scanned the active region twice, so we also report the stability of the velocity.

Motivation Matters: Lessons for REDD+ Participatory Measurement, Reporting and Verification from Three Decades of Child Health Participatory Monitoring in Indonesia.

Participatory Measurement, Reporting and Verification (PMRV), in the context of reducing emissions from deforestation and forest degradation with its co-benefits (REDD+) requires sustained monitoring and reporting by community members. This requirement appears challenging and has yet to be achieved. Other successful, long established, community self-monitoring and reporting systems may provide valuable lessons. The Indonesian integrated village healthcare program (Posyandu) was initiated in the 1980s and still provides effective and successful participatory measurement and reporting of child health status across the diverse, and often remote, communities of Indonesia. Posyandu activities focus on the growth and development of children under the age of five by recording their height and weight and reporting these monthly to the Ministry of Health. Here we focus on the local Posyandu personnel (kaders) and their motivations and incentives for contributing. While Posyandu and REDD+ measurement and reporting activities differ, there are sufficient commonalities to draw useful lessons. We find that the Posyandu kaders are motivated by their interests in health care, by their belief that it benefits the community, and by encouragement by local leaders. Recognition from the community, status within the system, training opportunities, competition among communities, and small payments provide incentives to sustain participation. We examine these lessons in the context of REDD+.

In South Korea, scrub typhus is the most common acute febrile illness in autumn. We analyzed scrub typhus cases reported from 2008 to 2012 to describe the epidemiology of scrub typhus as well as eschar patterns. A total of 30,478 cases were reported from 2008 to 2012; the incidence rates were higher in the southern and western regions of South Korea. The common clinical symptoms of confirmed scrub typhus cases from 2010 to 2012 were fever/chills (95.2%), eschars (78.9%), and myalgia (61.7%). The primary sites of eschars were the lower extremities (19.0%), abdomen/waist (13.4%), and axilla (11.5%) in men and the shoulder/frontal chest (15.1%), lower extremities (14.5%), and abdomen/waist (13.6%) in women. Regardless of gender, eschars tended to be more on the lower extremities among the leisure activities group. Among the occupational farm work group, who usually lived in rural areas, eschars appeared most frequently on the abdomen/waist in men and on the shoulder/frontal chest in women. Eschar patterns were influenced by gender and activities. These results could facilitate the prevention of scrub typhus and clarify the current status of scrub typhus in South Korea.

Male reproductive health has deteriorated in many countries during the last few decades. In the 1990s, declining semen quality has been reported from Belgium, Denmark, France, and Great Britain. The incidence of testicular cancer has increased during the same time incidences of hypospadias and cryptorchidism also appear to be increasing. Similar reproductive problems occur in many wildlife species. There are marked geographic differences in the prevalence of male reproductive disorders. While the reasons for these differences are currently unknown, both clinical and laboratory research suggest that the adverse changes may be inter-related and have a common origin in fetal life or childhood. Exposure of the male fetus to supranormal levels of estrogens, such as diethlylstilbestrol, can result in the above-mentioned reproductive defects. The growing number of reports demonstrating that common environmental contaminants and natural factors possess estrogenic activity presents the working hypothesis that the adverse trends in male reproductive health may be, at least in part, associated with exposure to estrogenic or other hormonally active (e.g., antiandrogenic) environmental chemicals during fetal and childhood development. An extensive research program is needed to understand the extent of the problem, its underlying etiology, and the development of a strategy for prevention and intervention. Images Figure 3.

Ketamine is a powerful anesthetic drug used in both human and veterinary surgery, but it is also commonly misused because of its psychotropic properties. Since the abuse of this drug has been reported in many countries worldwide, its determination in hair samples is offered as a specialist test by hundreds of laboratories. However, unlike other common drugs of abuse, a cut-off level for ketamine in hair has not been fixed yet. Therefore, aim of this study is to propose a concentration value for ketamine in hair analysis, in order to discriminate between chronic and occasional use, and between active use and external contamination. After considering the chemical properties of this molecule, and the experimental data collected in our laboratory or reported in several other published studies, we propose a cut-off level of 0.5ng/mg, as indicative of repeated exposure to ketamine. Additionally, we suggest that the detection of the metabolite norketamine should be mandatory to prove active intake and exclude false positive result from external contamination. Thus, a reasonable cut-off value for norketamine could be fixed at 0.1ng/mg, while the minimal concentration ratio norketamine/ketamine may be positively established at 0.05.

The aims of this study were to record behavioral problems in children with epilepsy (CWE), compare the prevalence with that reported among healthy children without epilepsy, and investigate the risk factors. A child behavioral questionnaire for parents comprising 15 items was administered to the main caregiver of 108 CWE and 108 controls matched for age in Kilifi, Kenya. CWE had a higher mean score for reported behavioral problems than controls (6.9 vs 4.9, t = 4.7, P < 0.001). CWE with active epilepsy also recorded more behavioral problems than those with inactive epilepsy (8.2 vs 6.2, t = − 2.9, P = 0.005). A significantly greater proportion of CWE (49% vs 26% of controls) were reported to have behavioral problems. Active epilepsy, cognitive impairment, and focal seizures were the most significant independent covariates of behavioral problems. Behavioral problems in African CWE are common and need to be taken into consideration in planning comprehensive clinical services in this region. PMID:22119107

To estimate the prevalence of vocal symptoms, occupational risk factors, associated symptoms and their impact on the professional activity of the telemarketers. Cross-section analytical study with 124 telemarketers and 109 administrative workers (control group) selected from a random sample stratified by gender. The subjects answered an anonymous self-administered questionnaire involving issues related to the presence of vocal symptoms, potential risk factors for dysphonia, and vocal impact of symptoms in professional activity. The presence of one or more voice symptoms that occurred daily or weekly was considered positive for the presence of vocal symptoms. The prevalence of vocal symptoms was found in 33% of telemarketers and in 21% of the control group, indicating an association between vocal symptoms and the activity of the telemarketer. When adjusted for confounders, this association remained in the sense of risk. In telemarketers, the sensation of dry air, ambient noise, and lack of vocal rest were the most frequently reported complaints reported by those presenting vocal symptoms. Almost 70% of telemarketers with vocal symptoms reported that these symptoms interfere with their professional activity. The rate of absenteeism by vocal symptoms in this group was 29%. Vocal symptoms are common in most telemarketers when compared to their peer controls, and significantly affect their job performance.

The Accelerator Physics Working Group addressed the worldwide R&D activities performed in support of future neutrino facilities. These studies cover R&D activities for Super Beam, Beta Beam and muon-based Neutrino Factory facilities. Beta Beam activities reported the important progress made, together with the research activity planned for the coming years. Discussion sessions were also organized jointly with other working groups in order to define common ground for the optimization of a future neutrino facility. Lessons learned from already operating neutrino facilities provide key information for the design of any future neutrino facility, and were also discussed in this meeting. Radiation damage, remote handling for equipment maintenance and exchange, and primary proton beam stability and monitoring were among the important subjects presented and discussed. Status reports for each of the facility subsystems were presented: proton drivers, targets, capture systems, and muon cooling and acceleration systems. The preferred scenario for each type of possible future facility was presented, together with the challenges and remaining issues. The baseline specification for the muon-based Neutrino Factory was reviewed and updated where required. This report will emphasize new results and ideas and discuss possible changes in the baseline scenarios of the facilities. A list of possible future steps is proposed that should be followed up at NuFact10.

Cereal consumption is a common dietary behavior that has been associated with positive health outcomes. The objective of this study was to examine prospective associations between cereal intake in childhood and percent body fat, waist-to-hip ratio, lipid levels, and physical activity during late adolescence. In this longitudinal investigation (data collected 1987-1997), data were analyzed for the 2,379 girls who participated in the 10-year National Heart, Lung, and Blood Institute Growth and Health Study. The cumulative percent of days that each girl consumed cereal during childhood (based on 3-day food diaries collected during six study visits between ages 11.5 and 18.6 years) was examined in relation to percent body fat, waist-to-hip ratio, lipid levels, and physical activity measured at age 18.6 years. Results indicated that nearly all girls (90.1%) reported eating cereal and 18.7% reported eating cereal on half or more of the days reported in the food diaries. Girls who ate cereal on a greater percentage of days during childhood had lower percent body fat and total cholesterol, and were more likely to exhibit high levels of physical activity and less television viewing during Study Year 10 (P values<0.05). Further research should explore lifestyle issues related to cereal consumption.

An Examination of College Student Activities and Attentiveness during a Web-Delivered Personalized Normative Feedback Intervention

Both heavy drinking and related risky sexual behavior among college students are common and are often associated with a number of negative consequences. A previously reported randomized controlled trial showed that a brief personalized normative feedback (PNF) intervention reduced the alcohol consumption and alcohol-related risky sexual behavior of heavy drinking, sexually active college students (Lewis et al., in press). For the present study, we examined what activities students were engaged in when viewing the feedback as well as who they were with and where they were when receiving the intervention. Furthermore, we conducted supplemental analyses with perceived attentiveness as a hypothesized predictor of change using the same sample (N = 480). Findings indicated that most students were engaged in activities when viewing the feedback and that most students viewed the feedback alone and at home. Furthermore, results revealed PNF to be most effective in reducing drinks per week among participants who reported greater attention. Clinical implications and suggestions for additional research examining how attentiveness can be increased during web-based interventions are discussed. PMID:25134036

2011-04-01

Protein arginine methylation is a common post-translational modification in eukaryotes that is catalyzed by a family of the protein arginine methyltransferases (PRMTs). PRMTs are classified into three types: type I and type II add asymmetrically and symmetrically dimethyl groups to arginine, respectively, while type III adds solely monomethyl group to arginine. However, although the enzymatic activity of type I and type II PRMTs have been reported, the substrate specificity and the methylation activity of type III PRMTs still remains unknown. Here, we report the characterization of Caenorhabditis elegans PRMT-2 and PRMT-3, both of which are highly homologous to human PRMT7. We find that these two PRMTs can bind to S-adenosyl methionine (SAM), but only PRMT-3 has methyltransferase activity for histone H2A depending on its SAM-binding domain. Importantly, thin-layer chromatographic analysis demonstrates that PRMT-3 catalyzes the formation of monomethylated, but not dimethylated arginine. Our study thus identifies the first type III PRMT in C. elegans and provides a means to elucidate the physiological significance of arginine monomethylation in multicellular organisms.

In-line skating, also known as rollerblading, is an increasingly popular recreational activity that carries with it the potential for injury. As reported in the Canadian Hospitals Injury Reporting and Prevention Program database (CHIRPP), 194 children were injured while in-line skating. Fractures to the radius and ulna were the most common type of injury sustained (57.5%), followed by lacerations and abrasions (14.9%). Five children had concussions and very few children reported wearing protective gear such as a helmet or wrist, elbow and knee protectors. Compared to the database overall, in-line skaters suffered more severe injuries and were more likely to require follow-up treatment. Safety implications in relation to protective gear and learning the sport of in-line skating are discussed.

The use of MDMA (ecstasy) in Australia is a widespread and growing problem, promoting acute toxicity and disease which can lead to premature death in users. We report four cases of fatal serotonin toxicity caused by the combination of MDMA and moclobemide, a reversible MAO-A inhibitor with potent serotonergic activity. Despite the highly reported toxicity of this drug combination, there are very few reports of fatalities attributed to a MDMA and moclobemide interaction. Pathology and toxicology reports, initial police reports and coroners' findings were examined to determine the circumstances of the deaths. Symptoms of some of the four cases as reported by paramedics and medical staff included hyperthermia, hyperkalemia, profuse sweating, twitching and shaking. Two cases involved moclobemide concentrations consistent with common prescribed doses, while the other two cases involved much higher concentrations often associated with toxicity. Three of these cases presented with some form of heart disease. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

To carry out an inventory on the availability, challenges, and needs of dietary assessment (DA) methods in Africa as a pre-requisite to provide evidence, and set directions (strategies) for implementing common dietary methods and support web-research infrastructure across countries. The inventory was performed within the framework of the "Africa's Study on Physical Activity and Dietary Assessment Methods" (AS-PADAM) project. It involves international institutional and African networks. An inventory questionnaire was developed and disseminated through the networks. Eighteen countries responded to the dietary inventory questionnaire. Various DA tools were reported in Africa; 24-Hour Dietary Recall and Food Frequency Questionnaire were the most commonly used tools. Few tools were validated and tested for reliability. Face-to-face interview was the common method of administration. No computerized software or other new (web) technologies were reported. No tools were standardized across countries. The lack of comparable DA methods across represented countries is a major obstacle to implement comprehensive and joint nutrition-related programmes for surveillance, programme evaluation, research, and prevention. There is a need to develop new or adapt existing DA methods across countries by employing related research infrastructure that has been validated and standardized in other settings, with the view to standardizing methods for wider use.

There are many biologically active organic molecules that contain one or more nitrogen-containing moieties, and broadly applicable and efficient catalytic transformations that deliver them diastereoselectively and/or enantioselectively are much sought after. Various methods for enantioselective synthesis of α-secondary amines are available (for example, from additions to protected/activated aldimines), but those involving ketimines are much less common. There are no reported additions of carbon-based nucleophiles to unprotected/unactivated (or N-H) ketimines. Here, we report a catalytic, diastereo- and enantioselective three-component strategy for merging an N-H ketimine, a monosubstituted allene and B2(pin)2, affording products in up to 95% yield, >98% diastereoselectivity and >99:1 enantiomeric ratio. The utility of the approach is highlighted by synthesis of the tricyclic core of a class of compounds that have been shown to possess anti-Alzheimer activity. Stereochemical models developed with the aid of density functional theory calculations, which account for the observed trends and levels of enantioselectivity, are presented.

The infection caused by Trichomonas vaginalis is the most common but overlooked non-viral sexually transmitted disease worldwide. Treatment relies on one class of drugs, the 5-nitroimidazoles, but resistance is widespread. New drugs are urgently needed. We reported the effect of crude and purified saponin fractions of Manilkara rufula against Trichomonas vaginalis. The compound responsible for antitrichomonal activity was isolated and identified as an uncommon bidesmosic saponin, Mi-saponin C. This saponin eliminated parasite viability without toxicity against the human vaginal epithelial line (HMVII). In addition, the isolated saponin fraction improved the metronidazole effect against a metronidazole-resistant isolate and dramatically reduced the cytoadherence of T. vaginalis to human cells. Investigation of the mechanism of death showed that the saponin fraction induced the parasite death due to profound membrane damage, inducing a disturbance of intracellular content without nuclear damage. To the best of our knowledge, this is the first report of antitrichomonal activity in the bidesmosic saponins of Manilkara rufula.

The present report the synthesis of palladium nanoparticles through the green method route offers few advantages over the common chemical and physical procedures, as it is an easy and fast, eco-friendly and does not involve any costly chemicals as well as hazardous chemicals. In this study, we reported synthesis of Pd NPs by using the Pimpinella tirupatiensis plant Extract (PTPE). The synthesized Pd NPs was characterization using different technique such as UV-Visible for the formation of Pd NPs. FT-IR spectroscopy was performed to detect the bio-active molecules liable for reduction and capping of biogenic Pd NPs. Crystallinity of Pd NPs conformed by powder - XRD. In the present study performed photo catalytic activity of synthesized Pd NPs using organic dye such as Congo red (CR). Hence, this study concludes the PTPE aqueous extract produced Pd NPs can be act as promising material for the degradation of organic pollutants.

Many researchers and professional bodies are seeking consensus for core outcomes for clinical trials. The Prevention of Falls Network Europe (ProFaNE) developed a common outcome data set for fall injury prevention trials 10 years ago. This study assesses the impact of these recommendations. A systematic search (up to 16 January 2015) was performed using Web of Science, Scopus and PubMed for articles citing the ProFaNE recommendations. Randomised trials on fall prevention in older people were selected for further analysis. Data were extracted on study characteristics and adherence to the key domains recommended by the ProFaNE consensus: falls, fall injury, physical activity, psychological consequences and health-related quality of life. Details of non-recommended outcome measures used were also recorded. The ProFaNE recommendations were cited in a total of 464 published articles, of which 34 were randomised trials on fall prevention in older people. Only one study (3 %) reported on all core domains. Most of the trials reported on falls (n = 32/34, 94 %) as a core outcome measure. Most of the recommendations within the falls domain were well-followed. Around half of the trials reported on fall-related injury (n = 16/34, 47 %). However, none reported the number of radiologically confirmed peripheral fracture events, which is the recommended outcome measure for injury. The other key domains (quality of life, physical activity and psychological consequences) were less frequently reported on, with a lack of consistency in the outcome measures used. The ProFaNE recommendations had a limited effect on standardising the reporting of outcomes in randomised trials on fall injury prevention in older people during the search period. Authors of consensus guidelines should consider maximising buy-in by including a diversity of geographic areas and academic disciplines at the development stage and using a solid dissemination strategy.

Screening for distress, the 6th vital sign: common problems in cancer outpatients over one year in usual care: associations with marital status, sex, and age

PubMed Central

2012-01-01

Background Very few studies examine the longitudinal prevalence of problems and the awareness or use of clinical programs by patients who report these problems. Of the studies that examine age, gender and marital status as predictors of a range of patient outcomes, none examines the interactions between these demographic variables. This study examined the typical trajectory of common practical and psychosocial problems endorsed over 12 months in a usual-care sample of cancer outpatients. Specifically, we examined whether marital status, sex, age, and their interactions predicted these trajectories. We did not actively triage or refer patients in this study in order to examine the natural course of problem reports. Methods Patients completed baseline screening (N = 1196 of 1707 approached) and the sample included more men (N = 696) than women (N = 498), average age 61.1 years. The most common diagnoses were gastrointestinal (27.1%), prostate (19.2%), skin (11.1%) and gynecological (9.2%). Among other measures, patients completed a Common Problem Checklist and Psychosocial Resources Use questions at baseline, 3, 6, and 12 months using paper and pencil surveys. Results Results indicated that patients reported psychosocial problems more often than practical and both decreased significantly over time. Younger single patients reported more practical problems than those in committed relationships. Younger patients and women of all ages reported more psychosocial problems. Among a number of interesting interactions, for practical problems, single older patients improved more; whereas among married people, younger patients improved more. For psychosocial problems we found that older female patients improved more than younger females, but among males, it was younger patients who improved more. Young single men and women reported the most past-and future-use of services. Conclusions Younger women are particularly vulnerable to experiencing practical and psychosocial problems when diagnosed with cancer, but being married protects these younger women. Marriage appeared to buffer reports of both practical and psychosocial problems, and led to less awareness and use of services. Unexpectedly, young men reported the highest use of psychosocial services. This study informs clinical program development with information on these risk groups. PMID:23031647

The American Heart Association (AHA) commends the recently released Institute of Medicine (IOM) report, Strategies to Improve Cardiac Arrest Survival: A Time to Act (2015). The AHA recognizes the unique opportunity created by the report to meaningfully advance the objectives of improving outcomes for sudden cardiac arrest. For decades, the AHA has focused on the goal of reducing morbidity and mortality from cardiovascular disease though robust support of basic, translational, clinical, and population research. The AHA also has developed a rigorous process using the best available evidence to develop scientific, advisory, and guideline documents. These core activities of development and dissemination of scientific evidence have served as the foundation for a broad range of advocacy initiatives and programs that serve as a foundation for advancing the AHA and IOM goal of improving cardiac arrest outcomes. In response to the call to action in the IOM report, the AHA is announcing 4 new commitments to increase cardiac arrest survival: (1) The AHA will provide up to $5 million in funding over 5 years to incentivize resuscitation data interoperability; (2) the AHA will actively pursue philanthropic support for local and regional implementation opportunities to increase cardiac arrest survival by improving out-of-hospital and in-hospital systems of care; (3) the AHA will actively pursue philanthropic support to launch an AHA resuscitation research network; and (4) the AHA will cosponsor a National Cardiac Arrest Summit to facilitate the creation of a national cardiac arrest collaborative that will unify the field and identify common goals to improve survival. In addition to the AHA's historic and ongoing commitment to improving cardiac arrest care and outcomes, these new initiatives are responsive to each of the IOM recommendations and demonstrate the AHA's leadership in the field. However, successful implementation of the IOM recommendations will require a timely response by all stakeholders identified in the report and a coordinated approach to achieve our common goal of improved cardiac arrest outcomes. © 2015 American Heart Association, Inc.

The Online GVP/USGS Weekly Volcanic Activity Report: Providing Timely Information About Worldwide Volcanism

The awesome power and intricate inner workings of volcanoes have made them a popular subject with scientists and the general public alike. About 1500 known volcanoes have been active on Earth during the Holocene, approximately 50 of which erupt per year. With so much activity occurring around the world, often in remote locations, it can be difficult to find up-to-date information about current volcanism from a reliable source. To satisfy the desire for timely volcano-related information the Smithsonian Institution and US Geological Survey combined their strengths to create the Weekly Volcanic Activity Report. The Smithsonian's Global Volcanism Program (GVP) has developed a network of correspondents while reporting worldwide volcanism for over 30 years in their monthly Bulletin of the Global Volcanism Network. The US Geological Survey's Volcano Hazards Program studies and monitors volcanoes in the United States and responds (upon invitation) to selected volcanic crises in other countries. The Weekly Volcanic Activity Report is one of the most popular sites on both organization's websites. The core of the Weekly Volcanic Activity Report is the brief summaries of current volcanic activity around the world. In addition to discussing various types of volcanism, the summaries also describe precursory activity (e.g. volcanic seismicity, deformation, and gas emissions), secondary activity (e.g. debris flows, mass wasting, and rockfalls), volcanic ash hazards to aviation, and preventative measures. The summaries are supplemented by links to definitions of technical terms found in the USGS photoglossary of volcano terms, links to information sources, and background information about reported volcanoes. The site also includes maps that highlight the location of reported volcanoes, an archive of weekly reports sorted by volcano and date, and links to commonly used acronyms. Since the Weekly Volcanic Activity Report's inception in November 2000, activity has been reported at over 60 volcanoes, with an average of 10 volcanoes discussed each week. Notable volcanic activity during November 2000-November 2001 included an eruption beginning on 6 February at Nyamuragira in the Democratic Republic of the Congo; it issued low-viscosity lava flows that traveled towards inhabited towns, and also produced ash clouds that adversely effected the health of residents and livestock near the volcano. Eruptions at Mayon in the Philippines on 24 June and 25 July caused local authorities to raise the alert to the highest level, close area airports, and evacuate thousands of residents near the volcano. Most recently a large flank eruption at Etna in Italy began on 17 July and gained worldwide attention as extensive lava flows threatened a small town and a tourist complex. While the information found in the Weekly Volcanic Activity Report, ranging from large eruptions to small precursory events, is of interest to the general public, it has also proven to be a valuable resource to volcano observatory staff, universities, researchers, secondary schools, and the aviation community.
