We assessed the prevalence of perceived abuse and discrimination among Arab American adults after September 11, 2001, and associations between abuse or discrimination and psychological distress, level of happiness, and health status. We gathered data from a face-to-face survey administered in 2003 to a representative, population-based sample of Arab American adults residing in the greater Detroit area. Overall, 25% of the respondents reported post-September 11 personal or familial abuse, and 15% reported that they personally had a bad experience related to their ethnicity, with higher rates among Muslims than Christians. After adjustment for socioeconomic and demographic factors, perceived post-September 11 abuse was associated with higher levels of psychological distress, lower levels of happiness, and worse health status. Personal bad experiences related to ethnicity were associated with increased psychological distress and reduced happiness. Perceptions of not being respected within US society and greater reported effects of September 11 with respect to personal security and safety were associated with higher levels of psychological distress. Perceived post-September 11 abuse and discrimination were associated with increased psychological distress, reduced levels of happiness, and worse health status in our sample. Community-based, culturally sensitive partnerships should be established to assess and meet the health needs of Arab Americans.

Objectives. We assessed the prevalence of perceived abuse and discrimination among Arab American adults after September 11, 2001, and associations between abuse or discrimination and psychological distress, level of happiness, and health status. Methods. We gathered data from a face-to-face survey administered in 2003 to a representative, population-based sample of Arab American adults residing in the greater Detroit area. Results. Overall, 25% of the respondents reported post–September 11 personal or familial abuse, and 15% reported that they personally had a bad experience related to their ethnicity, with higher rates among Muslims than Christians. After adjustment for socioeconomic and demographic factors, perceived post–September 11 abuse was associated with higher levels of psychological distress, lower levels of happiness, and worse health status. Personal bad experiences related to ethnicity were associated with increased psychological distress and reduced happiness. Perceptions of not being respected within US society and greater reported effects of September 11 with respect to personal security and safety were associated with higher levels of psychological distress. Conclusions. Perceived post–September 11 abuse and discrimination were associated with increased psychological distress, reduced levels of happiness, and worse health status in our sample. Community-based, culturally sensitive partnerships should be established to assess and meet the health needs of Arab Americans. PMID:20019301

The validity of self-report binge eating instruments among individuals with limited literacy is uncertain. This study aims to evaluate reading grade level and multiple domains of comprehension of 13 commonly used self-report assessments of binge eating for use in low-literacy populations. We evaluated self-report binge eating measures with respect to reading grade levels, measure length, formatting and linguistic problems. Results: All measures were written at a reading grade level higher than is recommended for patient materials (above the 5th to 6th grade level), and contained several challenging elements related to comprehension. Correlational analyses suggested that readability and comprehension elements were distinct contributors to measure difficulty. Individuals with binge eating who have low levels of educational attainment or limited literacy are often underrepresented in measure validation studies. Validity of measures and accurate assessment of symptoms depends on an individual's ability to read and comprehend instructions and items, and these may be compromised in populations with lower levels of literacy.

The objective of this study was to evaluate the impact of thermal stress on milk production and physiological traits of Baladi goats under subtropical Egyptian conditions. Sixty dairy Baladi goats were exposed to three different levels of temperature-humidity index (THI), including low (less than 70), moderate (over 70 and up to 80), and high levels (over 80). The influence of THI on the milk composition and physiological, hematological, and biochemical traits was investigated. Rectal temperature and respiration rate were significantly greater at the higher THI than at low and moderate THI (p = 0.016 and 0.002, respectively). Baladi goats had decreased daily milk yield in a rate of 27.3 and 19.3 % at high THI level, compared with low and moderate THI, respectively (p = 0.031). On the contrary, no significant differences have been reported in protein, fat, and total solids percentages at different THI levels. Total leucocyte count, serum glucose, and total protein were significantly reduced at high THI in comparison with low and moderate THI levels (p = 0.043, 0.001, and 0.001, respectively). However, dairy goats maintained relatively stable estimates for erythrocytes count, hemoglobin, serum triglycerides, cholesterol, catalase, total antioxidant capacity, and triiodothyronine at different THI levels. Our results indicate that dairy Baladi goats can tolerate THI levels up to 80; however, variable reduction in milk yield and few biochemical (serum total protein and glucose) and hematological (leucocytes count) parameters have been reported at a THI level higher than 80.

Omega-3 polyunsaturated fatty acids (PUFAs) such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been reported to reduce the risk of cardiovascular disease. However, whether omega-3 PUFAs are involved in the pathogenesis of abdominal aortic aneurysms (AAA) remains unclear. We analyzed 67 consecutive patients admitted for the elective surgical repair of AAA. We investigated the association of serum EPA and DHA levels as well as the EPA/AA ratio with the size of AAA assessed using three-dimensional reconstructed computed tomography images. Mean patient age was 70±9 years and 60 patients were male. Serum EPA and DHA levels were 75.2±35.7 μg/mL and 146.1±48.5 μg/mL, respectively. EPA/AA ratio was 0.44±0.22, which was lower than those in healthy Japanese subject and equivalent to those in Japanese patients with coronary artery disease as previously reported. Mean of the maximum AAA diameter was 56.4±8.9 mm, and serum EPA levels and EPA/AA ratio negatively correlated with it (r=-0.32 and r=-0.32, respectively). Multiple liner regression analysis showed that EPA levels were significant independent factor contributing to the maximum AAA diameter. Furthermore, low serum EPA levels and low EPA/AA ratio were significantly associated with the growth rate of AAA diameter (r=-0.43 and r=-0.33, respectively). EPA levels in patients with AAA were relatively low. Low serum EPA levels and EPA/AA ratio were associated with the size and growth rate of AAA.

The Roles of Respect for Parental Authority and Parenting Practices in Parent–Child Conflict Among African American, Latino, and European American Families

In this study, the authors examined whether parent–child conflict during the middle childhood years varied among families characterized as having different cultural traditions regarding issues of respect for parental authority and parenting practices. The sample included 133 African American, European American, and Latina girls (M age = 8.41 years) and their mothers. African American and Latina girls showed significantly more respect for parental authority than did European American girls. Furthermore, African American and Latina mothers reported significantly more intense arguments when respect was low than did European American mothers. Higher levels of discipline and better communication by mothers were both associated with reports of lower frequency of conflict; ethnicity did not moderate this association. Thus, respect for authority was most salient to group differences in conflict. PMID:18266527

This report summarizes outcomes of islet transplantation employing donors after cardiac death (DCD) between 2004 and 2007 as reported to the Japan Islet Transplantation Registry. Sixty-five islet isolations were performed for 34 transplantations in 18 patients with insulin-dependent diabetes mellitus, including two patients who had prior kidney transplantation. All but one donor (64/65) was DCD at the time of harvesting. Factors influencing criteria for islet release included duration of low blood pressure of the donor, cold ischemic time, and usage of Kyoto solution for preservation. Multivariate analysis selected usage of Kyoto solution as most important. Of the 18 recipients, 8, 4, and 6 recipients received 1, 2, and 3 islet infusions, respectively. Overall graft survival defined as C-peptide level more than or equal to 0.3 ng/mL was 76.5%, 47.1%, and 33.6% at 1, 2, and 3 years, respectively, whereas corresponding graft survival after multiple transplantations was 100%, 80.0%, and 57.1%, respectively. All recipients remained free of severe hypoglycemia while three achieved insulin independence for 14, 79, and 215 days. HbA1c levels and requirement of exogenous insulin were significantly improved in all patients. Islet transplantation employing DCD can ameliorate severe hypoglycemic episodes, significantly improve HbA1c levels, sustain significant levels of C-peptide, and achieve insulin independence after multiple transplantations. Thus, DCD can be an important resource for islet transplantation if used under strict releasing criteria and in multiple transplantations, particularly in countries where heart-beating donors are not readily available.

To investigate three different distraction methods (distraction cards, listening to music, and distraction cards + music) on pain and anxiety relief in children during phlebotomy. This study was a prospective, randomized, controlled trial. The sample consisted of children aged 7 to 12years who required blood tests. The children were randomized into four groups, distraction cards, music, distraction cards + music, and controls. Data were obtained through face-to-face interviews with the children, their parents, and the observer before and after the procedure. The children's pain levels were assessed and reported by the parents and observers, and the children themselves who self-reported using Wong-Baker FACES. The children's anxiety levels were also assessed using the Children's Fear Scale. Two hundred children (mean age: 9.01±2.35years) were included. No difference was found between the groups in the self, parent, and observer reported procedural pain levels (p=0.72, p=0.23, p=0.15, respectively). Furthermore, no significant differences were observed between groups in procedural child anxiety levels according to the parents and observer (p=0.092, p=0.096, respectively). Pain and anxiety relief was seen in all three methods during phlebotomy; however, no statistically significant difference was observed. Copyright © 2016 Elsevier Inc. All rights reserved.

2011-06-01

The objective of this study was to explore whether the time at which sex education was provided had any impact on reported cases of unintended pregnancies. A cross-sectional survey of secondary school students and their teachers was conducted using self-administered questionnaires. The participants were 1,234 students aged 14-17 years and 46 teachers in 5 secondary schools in South Eastern Nigeria. The outcome measures were reported pregnancies within the last 3 years by type of school and class level; class level at the time of receiving sex education at school; and age at the time of receiving sex education at home. In all schools, sex education was provided at all the junior and senior secondary school levels (JSS and SSS, respectively). Overall, reported cases of unintended pregnancies were highest among the junior students. In the private schools, four in ten teachers reported pregnancies among JSS 3 students. Almost four in ten teachers in public schools reported pregnancies among JSS 2 students. Of all the students, about three in ten reported pregnancies among JSS 2 and 3 students respectively. At home, sex education was provided at the mean age of 16 years (SD ± 2.2). All participants cited financial need and marital promise as major predisposing factors. About four in ten students did not use contraceptives during their first sexual experience. This study highlights the need to introduce sex education much earlier, possibly before the JSS levels. At home, sex education may have greater impact if provided before the age of 14 years. Efforts should be made to address the factors predisposing to teenage pregnancy.

This is the first case report of trisomy 13 complicated by massive fetomaternal hemorrhage (FMH). A pale male infant weighing 2,950 g was delivered with low Apgar scores by emergency cesarean section due to non-reassuring fetal status. The umbilical arterial pH and hemoglobin level were 6.815 and 6.9 g/dL (normal: 13 - 22 g/dL), respectively. The maternal hemoglobin-F and serum alpha-fetoprotein levels were 6.0% (normal: < 1.0%) and 1,150 ng/mL (4.1 multiple of median), respectively. The neonate was diagnosed as having trisomy 13 by a subsequent chromosome examination. In the placenta, massive intervillous thrombosis was observed microscopically. This placental finding has been reported to be associated with both preeclampsia and massive FMH. In addition, the incidence of preeclampsia in pregnancies complicated by trisomy 13 has been reported to be significantly higher than normal karyotype populations. Therefore, the current finding may support the association between trisomy 13 and the incidence of massive FMH. PMID:26015824

Tracking progress towards global newborn health targets depends largely on maternal reported data collected through large, nationally representative surveys. We evaluated the validity, across a range of recall period lengths (1 to 24 months post-delivery), of maternal report of birthweight, birth size and length of pregnancy. We compared maternal reports to reference standards of birthweights measured within 72 hours of delivery and gestational age generated from reported first day of the last menstrual period (LMP) prospectively collected as part of a population-based study (n = 1502). We calculated sensitivity, specificity, area the under the receiver operating curve (AUC) as a measure of individual-level accuracy, and the inflation factor (IF) to quantify population-level bias for each indicator. We assessed if length of recall period modified accuracy by stratifying measurements across time bins and using a modified Poisson regression with robust error variance to estimate the relative risk (RR) of correctly classifying newborns as low birthweight (LBW) or preterm, adjusting for child sex, place of delivery, maternal age, maternal education, parity, and ethnicity. The LBW indicator using maternally reported birthweight in grams had low individual-level accuracy (AUC = 0.69) and high population-level bias (inflation factor IF = 0.62). LBW using maternally reported birth size and the preterm birth indicator had lower individual-level accuracy (AUC = 0.58 and 0.56, respectively) and higher population-level bias (IF = 0.28 and 0.35, respectively) up to 24 months following birth. Length of recall time did not affect accuracy of LBW indicators. For the preterm birth indicator, accuracy did not change with length of recall up to 20 months after birth and improved slightly beyond 20 months. The use of maternal reports may underestimate and bias indicators for LBW and preterm birth. In settings with high prevalence of LBW and preterm births, these indicators generated from maternal reports may be more vulnerable to misclassification. In populations where an important proportion of births occur at home or where weight is not routinely measured, mothers perhaps place less importance on remembering size at birth. Further work is needed to explore whether these conclusions on the validity of maternal reports hold in similar rural and low-income settings.

Cervical arthroplasty is an increasingly popular alternative for the treatment of cervical radiculopathy and myelopathy. This technique preserves motion at the index and adjacent disc levels, avoiding the restraints of fusion and potentially minimizing adjacent segment pathology onset during the postoperative period. This study aimed to identify all prospective studies reporting adjacent segment pathology rates for cervical arthroplasty. Systematic review and meta-analysis were carried out. Studies reporting adjacent segment degeneration (ASDegeneration) and adjacent segment disease (ASDisease) rates in patients who underwent cervical arthroplasty comprised the patient sample. Outcomes of interest included reported ASDegeneration and ASDisease events after cervical arthroplasty. We conducted a MEDLINE, SCOPUS, and Web of Science search for studies reporting ASDegeneration or ASDisease following cervical arthroplasty. A meta-analysis was performed to calculate effect summary values, 95% confidence intervals (CIs), Q values, and I(2) values. Forest plots were constructed for each analysis group. Of the 1,891 retrieved articles, 32 met inclusion criteria. The patient incidence of ASDegeneration and ASDisease was 8.3% (95% CI 3.8%-12.7%) and 0.9% (95% CI 0.1%-1.7%), respectively. The rate of ASDegeneration and ASDisease at individual levels was 10.5% (95% CI 6.1%-14.9%) and 0.2% (95% CI -0.1% to 0.5%), respectively. Studies following patients for 12-24 months reported a 5.1% (95% CI 2.1%-8.1%) incidence of ASDegeneration and 0.2% (95% CI 0.1%-0.2%) incidence of ASDisease. Conversely, studies following patients for greater than 24 months reported a 16.6% (5.8%-27.4%) incidence of ASDegeneration and 2.6% (95% CI 1.0%-4.2%) of ASDisease. This identified a statistically significant increase in ASDisease diagnosis with lengthier follow-up. Additionally, 1- and 2-level procedures resulted in a 7.4% (95% CI 3.3%-11.4%) and15.6% (95 CI-9.2% to 40.4%) incidence of ASDegeneration, respectively. Although there was an 8.2% increase in ASDegeneration following 2-level operations (relative to 1-level), it did not reach statistical significance. We were unable to analyze ASDisease incidence following 2-level arthroplasty (too few cases), but 1-level operations resulted in an ASDisease incidence of 0.8% (95% CI 0.1%-1.5%). This review represents a comprehensive estimation of the actual incidence of ASDegeneration and ASDisease across a heterogeneous group of surgeons, patients, and arthroplasty techniques. Our investigation should serve as a framework for individual surgeons to understand the impact of various cervical arthroplasty techniques, follow-up duration, and surgical levels on the incidence of ASDegeneration and ASDisease during the postoperative period.

Abstract Background. As the proportion of the population aged 80 and over accelerates, so does the value of understanding the processes of aging well. The purposes of this article are to: (a) review contemporary theoretical and conceptual perspectives on aging well, (b) describe indicators of aging well that reflect key concepts and perspectives as assessed in the Women’s Health Initiative (WHI) and (c) characterize the status of aging among women aged 80 and older using data obtained from WHI participants at the WHI Extension 2 follow-up. Methods. Data from the Lifestyle Questionnaire, which was administered from 2011 to 2012 during the WHI Follow-up Study (Extension 2), were analyzed to provide a profile of the WHI cohort with respect to aging well. Results. Data revealed substantial diversity in the cohort with respect to the various measures of aging well. Although many reported physical functioning levels consistent with disability, most rated their health as good or better. Most reported moderately high levels of resilience, self-control, and self-mastery but lower levels of environmental mastery. Finally, the cohort reported high levels of optimal aging as reflected by their high levels of emotional well-being and moderately high levels of life satisfaction and social support, but more modest levels of personal growth and purpose in life. Conclusions. The wide range of some dimensions of aging well suggest that further examination of predictors of positive coping and resilience in the face of aging-related disability could identify opportunities to support and facilitate aging well among U.S. women.

The land-cover thematic accuracy of NLCD 2001 was assessed from a probability-sample of 15,000 pixels. Nationwide, NLCD 2001 overall Anderson Level II and Level I accuracies were 78.7% and 85.3%, respectively. By comparison, overall accuracies at Level II and Level I for the NLCD 1992 were 58% and 80%. Forest and cropland were two classes showing substantial improvements in accuracy in NLCD 2001 relative to NLCD 1992. NLCD 2001 forest and cropland user's accuracies were 87% and 82%, respectively, compared to 80% and 43% for NLCD 1992. Accuracy results are reported for 10 geographic regions of the United States, with regional overall accuracies ranging from 68% to 86% for Level II and from 79% to 91% at Level I. Geographic variation in class-specific accuracy was strongly associated with the phenomenon that regionally more abundant land-cover classes had higher accuracy. Accuracy estimates based on several definitions of agreement are reported to provide an indication of the potential impact of reference data error on accuracy. Drawing on our experience from two NLCD national accuracy assessments, we discuss the use of designs incorporating auxiliary data to more seamlessly quantify reference data quality as a means to further advance thematic map accuracy assessment.

Perceived exercise barriers explain exercise participation in Australian women treated for breast cancer better than perceived exercise benefits.

2014-12-01

This study aimed to determine the effect of perceived exercise benefits and barriers on exercise levels among women who have been treated for breast cancer and have not participated in a formal exercise intervention. This was an anonymous, national, online cross-sectional survey study. Four hundred thirty-two women treated for breast cancer completed an online survey covering their treatment and demographic background, current exercise levels, and perceived exercise benefits and barriers. Each perceived benefit and barrier was considered in a binary logistic regression against reported exercise levels to ascertain significant relationships and associative values (odds ratio [OR]). Agreement with 16 out of 19 exercise barriers was significantly related to being more likely to report insufficient exercise levels, whereas agreement with 6 out of 15 exercise benefits was significantly related to being less likely to report insufficient levels of exercise. Feeling too weak, lacking self-discipline, and not making exercise a priority were the barriers with the largest association to insufficient exercise levels (OR=10.97, 95% confidence interval [CI]=3.90, 30.86; OR=8.12, 95% CI=4.73, 13.93; and OR=7.43, 95% CI=3.72, 14.83, respectively). Conversely, exercise enjoyment, improved feelings of well-being, and decreased feelings of stress and tension were the top 3 benefits associated with being less likely to have insufficient exercise levels (OR=0.21, 95% CI=0.11, 0.39; OR=0.21, 95% CI=0.07, 0.63; and OR=0.31, 95% CI=0.15, 0.63, respectively). Self-reported data measures were used to collect exercise data. Targeting exercise barriers specific to women treated for breast cancer may improve exercise participation levels in this cohort. Awareness of the impact of exercise barriers identified in the present study will enable physical therapists to better plan exercise interventions that support all women treated for breast cancer. © 2014 American Physical Therapy Association.

Metal ions induced heat shock protein response by elevating superoxide anion level in HeLa cells transformed by HSE-SEAP reporter gene.

The aim of this work is to define the relationship between heat shock protein (HSP) and reactive oxygen species (ROS) in the cells exposed to different concentrations of metal ions, and to evaluate a new method for tracing the dynamic levels of cellular reactive oxygen species using a HSE-SEAP reporter gene. The expression of heat shock protein was measured using a secreted alkaline phosphatase (SEAP) reporter gene transformed into HeLa cell strain, the levels of superoxide anion (O(2)(-)) and hydrogen peroxide (H(2)O(2)) were determined by NBT reduction assay and DCFH staining flow cytometry (FCM), respectively. The experimental results demonstrated that the expression of heat shock protein induced by metal ions was linearly related to the cellular superoxide anion level before cytotoxic effects were observed, but not related to the cellular hydrogen peroxide level. The experimental results suggested that metal ions might induce heat shock protein by elevating cellular superoxide anion level, and thus the expression of heat shock protein indicated by the HSE-SEAP reporter gene can be an effective model for monitoring the dynamic level of superoxide anion and early metal-induced oxidative stress/cytotoxicity.

Emotion regulation in Asperger's syndrome and high-functioning autism.

PubMed

Samson, Andrea C; Huber, Oswald; Gross, James J

2012-08-01

It is generally thought that individuals with Asperger's syndrome and high-functioning autism (AS/HFA) have deficits in theory of mind. These deficits have been previously linked to problems with social cognition. However, we reasoned that AS/HFA individuals' Theory of Mind deficits also might lead to problems with emotion regulation. To assess emotional functioning in AS/HFA, 27 AS/HFA adults (16 women) and 27 age-, gender-, and education-matched typically developing (TD) participants completed a battery of measures of emotion experience, labeling, and regulation. With respect to emotion experience, individuals with AS/HFA reported higher levels of negative emotions, but similar levels of positive emotions, compared with TD individuals. With respect to emotion labeling, individuals with AS/HFA had greater difficulties identifying and describing their emotions, with approximately two-thirds exceeding the cutoff for alexithymia. With respect to emotion regulation, individuals with AS/HFA used reappraisal less frequently than TD individuals and reported lower levels of reappraisal self-efficacy. Although AS/HFA individuals used suppression more frequently than TD individuals, no difference in suppression self-efficacy was found. It is important to note that these differences in emotion regulation were evident even when controlling for emotion experience and labeling. Implications of these deficits are discussed, and future research directions are proposed.

The purpose of this paper is twofold: to validate the properties of the Italian version of the Baller Identity Measurement Scale (i.e., BIMS-IT), a self-report questionnaire based on the athletic and academic identities; and to investigate differences in psychosocial factors such as gender, age, type of sport, and competition level. The dimensionality of the BIMS-IT was explored by means of the exploratory factor analysis, considering the scale's internal consistency too (Confirmatory Factor Analysis). Results related to exploratory and confirmatory factor analysis supported a model of measurement composed of two correlated factors: the athletic and academic identities and affectivity related to identities. For both factors, differences emerged between age, and competition level sub groups. In particular, higher identity scores emerged for ≤ 24 years old student-athletes with respect to their age counterparts. National sub-elite student-athletes reported lower identity values than those of national elite and international levels. Results suggest that the Italian version of the BIMS-IT is psychometrically robust and could be adopted for empirical uses. The higher identity scores reported by younger and higher competition level participants suggest a correspondent higher involvement into the student-athlete role. However, BIMS-IT represents a distinct model with respect to the original American BIMS, determining the need of further research on the student-athletes' identity to better clarify any socio-cultural contest effects.

Animal studies have demonstrated the likely role of oxidative tissue damage in the pathophysiology of stone disease; however, the effect of antioxidants on stone formation in the human population is unknown. We evaluated the association between serum antioxidant levels and the self-reported prevalence of kidney stones in a large cross-sectional population in a retrospective cohort study. Serum levels of antioxidants among adult participants in the National Health and Nutrition Examination Survey (NHANES III) 1988-1994 were compared between those with and without a self-reported history of kidney stones, adjusting for covariates of age, sex, body mass index (BMI), race/ethnicity, diabetes, and hypertension. The prevalence of kidney stones was 5.25% (95% confidence interval: 4.60%, 5.90%). The prevalence of kidney stones was higher in males, white/non-Hispanics, diabetics, and those with hypertension. The prevalence of kidney stones increased with BMI. After adjusting for covariates, mean levels of alpha-carotene, beta-carotene, and beta-cryptoxanthin were significantly lower in those with kidney stones (-9.36%, -10.79%, and -8.48%, respectively). When analyzed by quartile, higher serum levels of beta-carotene and beta-cryptoxanthin,, trended toward a decreasing prevalence of stones (P=0.007 and P=0.03, respectively), indicating that the highest levels of these antioxidants may protect against the formation of kidney stones. Lower levels of alpha-carotene, beta-carotene, and beta-cryptoxanthin are associated with a history of kidney stones and may indicate a role for these antioxidants in preventing stone formation.

To provide a comprehensive review of clinical and functional outcomes after treatment for septic arthritis after anterior cruciate ligament reconstruction. A systematic review of the literature was performed. Two reviewers assessed and confirmed the methodologic quality of each study. Studies that met the inclusion criteria were assessed for pertinent data, and when available, similar outcomes were combined to generate frequency-weighted means. Nineteen studies met the inclusion and exclusion criteria for this review, reporting on a total of 203 infected knees. The mean age was 27.5 years and the mean length of follow-up was 44.2 months, with male patients comprising 88% of the population. Hamstring and bone-patellar tendon-bone autografts were used in 63% and 33% of patients, respectively, with 78% of patients retaining their grafts. The studies reported mean flexion and extension deficits of 5.8° and 1.0°, respectively, and laxity testing showed a mean difference of 1.9 mm. The studies reported mean Lysholm, International Knee Documentation Committee, and Tegner scores of 82.1, 68.2, and 5.6, respectively. Of the patients, 83% reported an ability to return to activities of daily living whereas 67% reported a return to their preinjury level of athletics. Evidence of new degenerative changes was seen in 22% of patients. Septic arthritis after anterior cruciate ligament reconstruction remains a very infrequent event, affecting 0.5% of patients. On average, outcomes in these patients are comparable with those in patients in whom infection does not develop, including postoperative range of motion, residual instability, Lysholm scores, and return to preinjury level of activity. These patients do exhibit decreased International Knee Documentation Committee scores compared with patients without septic arthritis, however. The impact of this differential is not clear, but this scoring difference suggests that septic arthritis may be associated with more severe symptoms and reduced functional outcomes. In addition, there is limited evidence suggesting that septic arthritis leads to early degenerative changes found on imaging. Level IV, systematic review of Level III and IV studies.

This study evaluates the level of agreement between self-reported vitamin D deficiency and serum vitamin D measured within the previous calendar year. In a study in which serum 25(OH)D levels were retrieved from electronic health records, 523 women were asked whether they considered themselves to have vitamin D deficiency. Serum vitamin D levels were categorized as vitamin D deficiency if serum 25(OH)D was <20 ng/ml and as insufficiency if <30 ng/ml. The kappa statistic was computed to assess the level of agreement between serum 25(OH)D level and self-report responses. Agreement between self-reported and measured 25(OH)D levels was poor. The kappa statistic was -0.041 when using a cutpoint of <20 ng/ml and -0.008 using the cutpoint of <30 ng/ml. Among women with levels ≥20 ng/ml, 82.4% believed that they were vitamin D deficient, while 13.3% who were below <20 ng/ml did not self-report deficiency. Among women who did not report vitamin D deficiency, 46.3% (37/80) had levels <20 ng/ml while 82.5% (66/80) had levels <30 ng/ml. These findings suggest that, although the prevalence of 25(OH)D <20 and <30 ng/ml was quite high (53.2% and 84.7%, respectively), there was little agreement between measured levels and self-report of vitamin D deficiency. This may be due to belief in this region that low levels of serum vitamin D is widespread. Better communication is needed between healthcare providers and patients regarding transmission of laboratory results. © 2015 Wiley Periodicals, Inc.

Statin-associated muscular and renal adverse events: data mining of the public version of the FDA adverse event reporting system.

PubMed

Sakaeda, Toshiyuki; Kadoyama, Kaori; Okuno, Yasushi

2011-01-01

Adverse event reports (AERs) submitted to the US Food and Drug Administration (FDA) were reviewed to assess the muscular and renal adverse events induced by the administration of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) and to attempt to determine the rank-order of the association. After a revision of arbitrary drug names and the deletion of duplicated submissions, AERs involving pravastatin, simvastatin, atorvastatin, or rosuvastatin were analyzed. Authorized pharmacovigilance tools were used for quantitative detection of signals, i.e., drug-associated adverse events, including the proportional reporting ratio, the reporting odds ratio, the information component given by a Bayesian confidence propagation neural network, and the empirical Bayes geometric mean. Myalgia, rhabdomyolysis and an increase in creatine phosphokinase level were focused on as the muscular adverse events, and acute renal failure, non-acute renal failure, and an increase in blood creatinine level as the renal adverse events. Based on 1,644,220 AERs from 2004 to 2009, signals were detected for 4 statins with respect to myalgia, rhabdomyolysis, and an increase in creatine phosphokinase level, but these signals were stronger for rosuvastatin than pravastatin and atorvastatin. Signals were also detected for acute renal failure, though in the case of atorvastatin, the association was marginal, and furthermore, a signal was not detected for non-acute renal failure or for an increase in blood creatinine level. Data mining of the FDA's adverse event reporting system, AERS, is useful for examining statin-associated muscular and renal adverse events. The data strongly suggest the necessity of well-organized clinical studies with respect to statin-associated adverse events.

Engineers regularly analyze SSME ground test and flight data with respect to engine systems performance. Recently, a redesigned SSME powerhead was introduced to engine-level testing in part to increase engine operational margins through optimization of the engine internal environment. This paper presents an overview of the MSFC personnel engine systems analysis results and conclusions reached from initial engine level testing of the redesigned powerhead, and further redesigns incorporated to eliminate accelerated main injector baffle and main combustion chamber hot gas wall degradation. The conclusions are drawn from instrumented engine ground test data and hardware integrity analysis reports and address initial engine test results with respect to the apparent design change effects on engine system and component operation.

The aim of this study was to assess the relationship between self-reported weight change, socio-economic status, and health-related quality of life (HRQOL) in patients with diabetes, 5 years after they underwent coronary angiography. Between 2013 and 2014, 1873 of 4391 patients (319 with diabetes) who underwent coronary angiography between 2008 and 2009 participated in a follow-up study. Three out of four domains of the World Health Organization Quality of Life (WHOQOL)-BREF (physical health, psychological health and social relationships) were surveyed during the follow-up period. To assess the relationship between weight change and HRQOL, generalized linear models were constructed for every dimension of the WHOQOL-BREF, with educational level as a predictor and sex, age, marital status, smoking status, hypertension, cholesterol, ischemic heart disease, acute myocardial infarction, and stable angina pectoris as covariates. The mean age of the patients was 70 years and almost three-quarters of the patients (72.7 %) were men. During the 12 months preceding the follow-up survey, 22.6 % of the patients reported weight loss, 20 % reported weight gain, and 57.4 % reported no weight change. There were significant differences in the HRQOL scores between patients who reported weight loss and those who reported either weight gain or unchanged weight. The most affected domains were physical and psychological health, with higher scores for patients who reported weight loss (54.7 and 67.2, respectively) than those who reported weight gain (46.3 and 58.5, respectively). The generalized linear model confirmed higher HRQOL scores among patients who reported weight loss and revealed an association between the HRQOL score and education level. Weight change and education level were associated with HRQOL in patients with diabetes. Self-reported weight loss and no weight change were positively associated with HRQOL in patients with diabetes, while weight gain was negatively associated with HRQOL.

There is some initial evidence that an enhanced physical activity level can improve fquality of life, and possibly survival among patients with lung cancer. The primary aim of this project was to evaluate the impact of physical activity on the quality and quantity of life of lung cancer survivors. Between January 1, 1997, and December 31, 2009, a total of 1466 lung cancer survivors completed a questionnaire with patient-reported outcomes for quality of life (QOL), demographics, disease and clinical characteristics, and a measure of physical activity (Baecke Questionnaire). Chi-square tests compared lung cancer survivors who reported being physically active versus not on a variety of the other covariates. Kaplan-Meier estimates and Cox models evaluated the prognostic importance of physical activity level on Overall Survival (OS). Roughly half of the lung cancer survivors had advanced stage disease at the time of survey. Treatment prevalence rates were 61, 54, and 33 % for surgery, chemotherapy and radiotherapy, respectively. The majority (77 %) of survivors reported themselves as physically active. Physically active survivors reported greater activity across all individual Baecke items. Lung cancer survivor-reported QOL indicated the benefits of physical activity in all domains. Survivors receiving chemotherapy or radiation at the time of questionnaire completion were less likely to be physically active (74 and 73 % respectively). In contrast, 84 % of surgical patients were physically active. Disease recurrence rates were the same for physically active and inactive patients (81 % vs 82 %, p = 0.62). Physically active patients survived an average of 4 more years than those who were not physically active (8.4 years versus 4.4 years respectively, log rank p < 0.0001). Being physically active was related to profound advantages in QOL and survival in a large sample of lung cancer survivors.

Lead levels were measured by inductively coupled plasma mass spectrometry (ICP-MS) in umbilical cord blood samples of 150 neonates in an urban inner-city hospital. The mean (SD) gestation and birth weight of our cohort were 38.8 (1.7) weeks and 3,217 (519) grams. There were 89% African-Americans, 53% males and 79% were born via vaginal delivery. Mean (SD) maternal age was 24.5 (5.8) years. History of drug abuse and smoking was reported in 8.7% and 10.7% respectively, with only 1 mother reporting a history of high lead level in childhood. Prenatal vitamin intake was reported in 99.3%. Cord blood lead level was available in 144 patients, with lead level of <1μg/dL seen in 141 (97.9%) and>1 in 3 (2.1%) patients. No patient had cord blood lead level of >2μg/dL. High lead levels during childhood in high-risk urban population, however, suggest the need for intensive efforts for prevention of environmental exposure to lead in early childhood.

Background Sugar-sweetened beverage (SSB) consumption among children and adolescents is a determinant of childhood obesity. Many programs to reduce consumption across the socio-ecological model report significant positive results; however, the generalizability of the results, including whether reporting differences exist among socio-ecological strategy levels, is unknown. Objectives This systematic review aims to (1) examine the extent to which studies reported internal and external validity indicators defined by RE-AIM (reach, effectiveness, adoption, implementation, maintenance) and (2) assess reporting differences by socio-ecological level: intrapersonal/interpersonal (Level 1), environmental/policy (Level 2), multi-level (Combined Level). Methods Six major databases (PubMed, Web of Science, Cinahl, CAB Abstracts, ERIC, and Agiricola) systematic literature review was conducted to identify studies from 2004–2015 meeting inclusion criteria (targeting children aged 3–12, adolescents 13–17, and young adults 18 years, experimental/quasi-experimental, substantial SSB component). Interventions were categorized by socio-ecological level, and data were extracted using a validated RE-AIM protocol. A one-way ANOVA assessed differences between levels. Results There were 55 eligible studies (N) accepted, including 21 Level 1, 18 Level 2, and 16 Combined Level studies. Thirty-six (65%) were conducted in the USA, 19 (35%) internationally, and 39 (71%) were implemented in schools. Across levels, reporting averages were low for all RE-AIM dimensions (reach=29%, efficacy/effectiveness=45%, adoption=26%, implementation=27%, maintenance=14%). Level 2 studies had significantly lower reporting on reach and effectiveness (10% and 26%, respectively) compared to Level 1 (44%, 57%) or Combined Level studies (31%, 52%) (p<0.001). Adoption, implementation, and maintenance reporting did not vary among levels. Conclusion Interventions to reduce SSB in children and adolescents across the socio-ecological spectrum do not provide the necessary information for dissemination and implementation in community nutrition settings. Future interventions should address both internal and external validity to maximize population impact. PMID:27262383

Physical activity assessment: biomarkers and self-report of activity-related energy expenditure in the WHI.

We used a biomarker of activity-related energy expenditure (AREE) to assess measurement properties of self-reported physical activity and to determine the usefulness of AREE regression calibration equations in the Women's Health Initiative. Biomarker AREE, calculated as the total energy expenditure from doubly labeled water minus the resting energy expenditure from indirect calorimetry, was assessed in 450 Women's Health Initiative participants (2007-2009). Self-reported AREE was obtained from the Arizona Activity Frequency Questionnaire (AAFQ), the 7-Day Physical Activity Recall (PAR), and the Women's Health Initiative Personal Habits Questionnaire (PHQ). Eighty-eight participants repeated the protocol 6 months later. Reporting error, measured as log(self-report AREE) minus log(biomarker AREE), was regressed on participant characteristics for each instrument. Body mass index was associated with underreporting on the AAFQ and PHQ but overreporting on PAR. Blacks and Hispanics underreported physical activity levels on the AAFQ and PAR, respectively. Underreporting decreased with age for the PAR and PHQ. Regressing logbiomarker AREE on logself-reported AREE revealed that self-report alone explained minimal biomarker variance (R(2) = 7.6, 4.8, and 3.4 for AAFQ, PAR, and PHQ, respectively). R(2) increased to 25.2, 21.5, and 21.8, respectively, when participant characteristics were included. Six-month repeatability data adjusted for temporal biomarker variation, improving R(2) to 79.4, 67.8, and 68.7 for AAFQ, PAR, and PHQ, respectively. Calibration equations "recover" substantial variation in average AREE and valuably enhance AREE self-assessment.

To characterize patient-level clinically meaningful improvements in pain and limitation of key activities of daily living (ADLs) after primary or revision total hip arthroplasty (THA). We analysed prospectively collected data from the Mayo Clinic Total Joint Registry to study clinically meaningful improvements in index hip pain severity and limitation in seven key ADLs (walking, climbing stairs, putting on shoes/socks, picking up objects, getting in/out of car, rising from a chair and sitting), from preoperative to 2- and 5-year post-THA. The primary THA cohort consisted of 6168 responders preoperatively, 5707 at 2 years and 3289 at 5 years postoperatively. The revision THA cohort consisted of 2063 responders preoperatively, 2682 at 2 years and 1627 at 5 years postoperatively. In the primary THA cohort, clinically meaningful pain reduction to mild or no hip pain at 2 years was reported by 94% with moderate and 91% with severe preoperative pain; respective proportions were 91% and 89% at 5-year follow-up. For revision THA, respective proportions were 84% and 77% at 2 years and 80% and 78% at 5 years. In the primary THA cohort, up to 4% with moderate and 17% with severe preoperative ADL limitation reported severe limitation in the respective activity 2 years post-primary THA; at 5 years, the respective proportions were up to 7% and 20%. Respective proportions for revision THA were up to 10% and 26% at 2 years and 13% and 30% at 5 years. These comprehensive data for patient-level clinically meaningful improvements in pain and seven key ADLs can help patients set realistic goals for improvement after THA.

Increase in salivary oxytocin and decrease in salivary cortisol after listening to relaxing slow-tempo and exciting fast-tempo music.

Relaxation and excitation are components of the effects of music listening. The tempo of music is often considered a critical factor when determining these effects: listening to slow-tempo and fast-tempo music elicits relaxation and excitation, respectively. However, the chemical bases that underlie these relaxation and excitation effects remain unclear. Since parasympathetic and sympathetic nerve activities are facilitated by oxytocin and glucocorticoid, respectively, we hypothesized that listening to relaxing slow-tempo and exciting fast-tempo music is accompanied by increases in the oxytocin and cortisol levels, respectively. We evaluated the change in the salivary oxytocin and cortisol levels of participants listening to slow-tempo and fast-tempo music sequences. We measured the heart rate (HR) and calculated the heart rate variability (HRV) to evaluate the strength of autonomic nerve activity. After listening to a music sequence, the participants rated their arousal and valence levels. We found that both the salivary oxytocin concentration and the high frequency component of the HRV (HF) increased and the HR decreased when a slow-tempo music sequence was presented. The salivary cortisol level decreased and the low frequency of the HRV (LF) to HF ratio (LF/HF) increased when a fast-tempo music sequence was presented. The ratio of the change in the oxytocin level was correlated with the change in HF, LF/HF and HR, whereas that in the cortisol level did not show any correlation with indices of autonomic nerve activity. There was no correlation between the change in oxytocin level and self-reported emotions, while the change in cortisol level correlated with the arousal level. These findings suggest that listening to slow-tempo and fast-tempo music is accompanied by an increase in the oxytocin level and a decrease in the cortisol level, respectively, and imply that such music listening-related changes in oxytocin and cortisol are involved in physiological relaxation and emotional excitation, respectively.

AIM To determine if patients can localise dysphagia level determined endoscopically or radiologically and association of gender, age, level and pathology. METHODS Retrospective review of consecutive patients presenting to dysphagia hotline between March 2004 and March 2015 was carried out. Demographics, clinical history and investigation findings were recorded including patient perception of obstruction level (pharyngeal, mid sternal or low sternal) was documented and the actual level of obstruction found on endoscopic or radiological examination (if any) was noted. All patients with evidence of obstruction including oesophageal carcinoma, peptic stricture, Schatzki ring, oesophageal pouch and cricopharyngeal hypertrophy were included in the study who had given a perceived level of dysphagia. The upper GI endoscopy reports (barium study where upper GI endoscopy was not performed) were reviewed to confirm the distance of obstructing lesion from central incisors. A previously described anatomical classification of oesophagus was used to define the level of obstruction to be upper, middle or lower oesophagus and this was compared with patient perceived level. RESULTS Three thousand six hundred and sixty-eight patients were included, 42.0% of who were female, mean age 70.7 ± 12.8 years old. Of those with obstructing lesions, 726 gave a perceived level of dysphagia: 37.2% had oesophageal cancer, 36.0% peptic stricture, 13.1% pharyngeal pouches, 10.3% Schatzki rings and 3.3% achalasia. Twenty-seven point five percent of patients reported pharyngeal level (upper) dysphagia, 36.9% mid sternal dysphagia and 25.9% lower sternal dysphagia (9.5% reported multiple levels). The level of obstructing lesion seen on diagnostic testing was upper (17.2%), mid (19.4%) or lower (62.9%) or combined (0.3%). When patients localised their level of dysphagia to a single level, the kappa statistic was 0.245 (P < 0.001), indicating fair agreement. 48% of patients reporting a single level of dysphagia were accurate in localising the obstructing pathology. With respect to pathology, patients with pharyngeal pouches were most accurate localising their level of dysphagia (P < 0.001). With respect to level of dysphagia, those with pharyngeal level lesions were best able to identify the level of dysphagia accurately (P < 0.001). No association (P > 0.05) was found between gender, patient age or clinical symptoms with their ability to detect the level of dysphagia. CONCLUSION Patient perceived level of dysphagia is unreliable in determining actual level of obstructing pathology and should not be used to tailor investigations. PMID:28246477

With respect to level of dysphagia, those with pharyngeal level lesions were best able to identify the level of dysphagia accurately ( P < 0.001). No association ( P > 0.05) was found between gender, patient age or clinical symptoms with their ability to detect the level of dysphagia. Patient perceived level of dysphagia is unreliable in determining actual level of obstructing pathology and should not be used to tailor investigations.

Wearable activity monitors such as Fitbit enable users to track various attributes of their physical activity (PA) over time and have the potential to be used in research to promote and measure PA behavior. However, the measurement accuracy of Fitbit in absolute free-living conditions is largely unknown. To examine the measurement congruence between Fitbit Flex and ActiGraph GT3X for quantifying steps, metabolic equivalent tasks (METs), and proportion of time in sedentary activity and light-, moderate-, and vigorous-intensity PA in healthy adults in free-living conditions. A convenience sample of 19 participants (4 men and 15 women), aged 18-37 years, concurrently wore the Fitbit Flex (wrist) and ActiGraph GT3X (waist) for 1- or 2-week observation periods (n=3 and n=16, respectively) that included self-reported bouts of daily exercise. Data were examined for daily activity, averaged over 14 days and for minutes of reported exercise. Average day-level data included steps, METs, and proportion of time in different intensity levels. Minute-level data included steps, METs, and mean intensity score (0 = sedentary, 3 = vigorous) for overall reported exercise bouts (N=120) and by exercise type (walking, n=16; run or sports, n=44; cardio machine, n=20). Measures of steps were similar between devices for average day- and minute-level observations (all P values > .05). Fitbit significantly overestimated METs for average daily activity, for overall minutes of reported exercise bouts, and for walking and run or sports exercises (mean difference 0.70, 1.80, 3.16, and 2.00 METs, respectively; all P values < .001). For average daily activity, Fitbit significantly underestimated the proportion of time in sedentary and light intensity by 20% and 34%, respectively, and overestimated time by 3% in both moderate and vigorous intensity (all P values < .001). Mean intensity scores were not different for overall minutes of exercise or for run or sports and cardio-machine exercises (all P values > .05). Fitbit Flex provides accurate measures of steps for daily activity and minutes of reported exercise, regardless of exercise type. Although the proportion of time in different intensity levels varied between devices, examining the mean intensity score for minute-level bouts across different exercise types enabled interdevice comparisons that revealed similar measures of exercise intensity. Fitbit Flex is shown to have measurement limitations that may affect its potential utility and validity for measuring PA attributes in free-living conditions.

Trait Variance and Response Style Variance in the Scales of the Personality Inventory for DSM-5 (PID-5).

2017-01-01

Using self- and observer reports on the Personality Inventory for DSM-5 (PID-5) and the HEXACO Personality Inventory-Revised (HEXACO-PI-R), we identified for each inventory several trait dimensions (each defined by both self- and observer reports on the facet-level scales belonging to the same domain) and 2 source dimensions (each defined by self-reports or by observer reports, respectively, on all facet-level scales). Results (N = 217) showed that the source dimensions of the PID-5 were very large (much larger than those of the HEXACO-PI-R), and suggest that self-report (or observer report) response styles substantially inflate the intercorrelations and the alpha reliabilities of the PID-5 scales. We discuss the meaning and the implications of the large PID-5 source components, and we suggest some methods of controlling their influence.

Calcium, phosphorus, magnesium and vitamin D have important biological roles in the body, especially in bone metabolism. We aimed to study the reported intake, the disparity between the reported consumption and the level needed for adequacy and food sources of these four nutrients in the Spanish population. We assessed the reported intake for both, general population and plausible reporters. Results were extracted from the ANIBES survey, n = 2009. Three-day dietary reported intake data were obtained and misreporting was assessed according to the European Food Safety Authority (EFSA). Mean ± SEM (range) total reported consumption of calcium, phosphorus, magnesium, and vitamin D for the whole population were 698 ± 7 mg/day (71-2551 mg/day), 1176 ± 8 mg/day, (331-4429 mg/day), 222 ± 2 mg/day (73-782 mg/day), and 4.4 ± 0.1 µg/day (0.0-74.2 µg/day), respectively. In the whole group, 76% and 66%; 79% and 72%; and 94% and 93% of the population had reported intakes below 80% of the national and European recommended daily intakes for calcium, magnesium and vitamin D, respectively; these percentages were over 40% when the plausible reporters were analysed separately. The main food sources were milk and dairy products for calcium and phosphorus, cereals and grains for magnesium and fish for vitamin D. In conclusion, there is an important percentage of the Spanish ANIBES population not meeting the recommended intakes for calcium, magnesium and vitamin D.

Characteristics of Medical Research News Reported on Front Pages of Newspapers

Lai, William Yuk Yeu; Lane, Trevor

2009-01-01

Background The placement of medical research news on a newspaper's front page is intended to gain the public's attention, so it is important to understand the source of the news in terms of research maturity and evidence level. Methodology/Principal Findings We searched LexisNexis to identify medical research reported on front pages of major newspapers published from January 1, 2000 to December 31, 2002. We used MEDLINE and Google Scholar to find journal articles corresponding to the research, and determined their evidence level. Of 734 front-page medical research stories identified, 417 (57%) referred to mature research published in peer-reviewed journals. The remaining 317 stories referred to preliminary findings presented at scientific or press meetings; 144 (45%) of those stories mentioned studies that later matured (i.e. were published in journals within 3 years after news coverage). The evidence-level distribution of the 515 journal articles quoted in news stories reporting on mature research (3% level I, 21% level II, 42% level III, 4% level IV, and 31% level V) differed from that of the 170 reports of preliminary research that later matured (1%, 19%, 35%, 12%, and 33%, respectively; chi-square test, P = .0009). No news stories indicated evidence level. Fewer than 1 in 5 news stories reporting preliminary findings acknowledged the preliminary nature of their content. Conclusions/Significance Only 57% of front-page stories reporting on medical research are based on mature research, which tends to have a higher evidence level than research with preliminary findings. Medical research news should be clearly referenced and state the evidence level and limitations to inform the public of the maturity and quality of the source. PMID:19568422

DJ-1 is a multifunctional protein implicated in redox dependent cell fate decisions. The aim of our study was to determine the pleural fluid (PF) levels of DJ-1 in malignant pleural effusions (MPEs) secondary to lung cancer. Additionally, we opted to assess potential correlations of DJ-1 PF levels with the PF levels of superoxide dismutase-1 (SOD1) and 8-isoprostane that are known antioxidant enzymes and have been previously reported in MPEs. Forty lung cancer patients with cytological proof of MPE were enrolled in this study. The PF levels of DJ-1, SOD1, and 8-isoprostane were measured by means of enzyme-linked immunosorbent assay. The median PF levels of DJ-1 were 826 ng/mL (interquartile range, IQR: 482-1010 ng/mL). DJ-1 PF levels significantly correlated with PF Cu/Zn-SOD1 and PF 8-isoprostane levels (Spearman's rho, r; r = -0.476, P = 0.002 and r = -0.264, P = 0.033, respectively), PF lactate dehydrogenase (r = -0.497, P = 0.001) and total PF cell counts (r = -0.325, P = 0.041). Finally, in patients aged over 65 the PF DJ-1 levels were significantly higher than patients aged less than 65 (875 ng/mL vs. 607 ng/mL, respectively, P = 0.037). To our knowledge, this is the first report to determine DJ-1's levels in MPEs due to lung cancer. The negative correlations between DJ-1, SOD1, and 8-isorpostane warrant further investigation regarding the altered redox regulation associated with MPEs.

Mastitis imposes considerable and recurring economic losses on the dairy industry worldwide. The main objective of this study was to estimate herd-level costs incurred by expenditures and production losses associated with mastitis on Canadian dairy farms in 2015, based on producer reports. Previously, published mastitis economic frameworks were used to develop an economic model with the most important cost components. Components investigated were divided between clinical mastitis (CM), subclinical mastitis (SCM), and other costs components (i.e., preventive measures and product quality). A questionnaire was mailed to 374 dairy producers randomly selected from the (Canadian National Dairy Study 2015) to collect data on these costs components, and 145 dairy producers returned a completed questionnaire. For each herd, costs due to the different mastitis-related components were computed by applying the values reported by the dairy producer to the developed economic model. Then, for each herd, a proportion of the costs attributable to a specific component was computed by dividing absolute costs for this component by total herd mastitis-related costs. Median self-reported CM incidence was 19 cases/100 cow-year and mean self-reported bulk milk somatic cell count was 184,000 cells/mL. Most producers reported using post-milking teat disinfection (97%) and dry cow therapy (93%), and a substantial proportion of producers reported using pre-milking teat disinfection (79%) and wearing gloves during milking (77%). Mastitis costs were substantial (662 CAD per milking cow per year for a typical Canadian dairy farm), with a large portion of the costs (48%) being attributed to SCM, and 34 and 15% due to CM and implementation of preventive measures, respectively. For SCM, the two most important cost components were the subsequent milk yield reduction and culling (72 and 25% of SCM costs, respectively). For CM, first, second, and third most important cost components were culling (48% of CM costs), milk yield reduction following the CM events (34%), and discarded milk (11%), respectively. This study is the first since 1990 to investigate costs of mastitis in Canada. The model developed in the current study can be used to compute mastitis costs at the herd and national level in Canada.

Errors in accident data, its types, causes and methods of rectification-analysis of the literature.

Most of the decisions taken to improve road safety are based on accident data, which makes it the back bone of any country's road safety system. Errors in this data will lead to misidentification of black spots and hazardous road segments, projection of false estimates pertinent to accidents and fatality rates, and detection of wrong parameters responsible for accident occurrence, thereby making the entire road safety exercise ineffective. Its extent varies from country to country depending upon various factors. Knowing the type of error in the accident data and the factors causing it enables the application of the correct method for its rectification. Therefore there is a need for a systematic literature review that addresses the topic at a global level. This paper fulfils the above research gap by providing a synthesis of literature for the different types of errors found in the accident data of 46 countries across the six regions of the world. The errors are classified and discussed with respect to each type and analysed with respect to income level; assessment with regard to the magnitude for each type is provided; followed by the different causes that result in their occurrence, and the various methods used to address each type of error. Among high-income countries the extent of error in reporting slight, severe, non-fatal and fatal injury accidents varied between 39-82%, 16-52%, 12-84%, and 0-31% respectively. For middle-income countries the error for the same categories varied between 93-98%, 32.5-96%, 34-99% and 0.5-89.5% respectively. The only four studies available for low-income countries showed that the error in reporting non-fatal and fatal accidents varied between 69-80% and 0-61% respectively. The logistic relation of error in accident data reporting, dichotomised at 50%, indicated that as the income level of a country increases the probability of having less error in accident data also increases. Average error in recording information related to the variables in the categories of location, victim's information, vehicle's information, and environment was 27%, 37%, 16% and 19% respectively. Among the causes identified for errors in accident data reporting, Policing System was found to be the most important. Overall 26 causes of errors in accident data were discussed out of which 12 were related to reporting and 14 were related to recording. "Capture-Recapture" was the most widely used method among the 11 different methods: that can be used for the rectification of under-reporting. There were 12 studies pertinent to the rectification of accident location and almost all of them utilised a Geographical Information System (GIS) platform coupled with a matching algorithm to estimate the correct location. It is recommended that the policing system should be reformed and public awareness should be created to help reduce errors in accident data. Copyright © 2017 Elsevier Ltd. All rights reserved.

2017-08-01

Historically poor results of survivorship and functional outcomes of patellofemoral arthroplasty (PFA) have been reported in the setting of isolated patellofemoral osteoarthritis. More recently, however, fairly good results of PFA were reported, but the current status of PFA outcomes is unknown. Therefore, a systematic review was performed to assess overall PFA survivorship and functional outcomes. A search was performed using PubMed, Embase and Cochrane systems, and the registries were searched. Twenty-three cohort studies and one registry reported survivorship using Kaplan-Meier curve, while 51 cohort studies reported functional outcomes of PFA. Twelve studies were level II studies, while 45 studies were level III or IV studies. Heterogeneity was mainly seen in type of prosthesis and year the cohort started. Nine hundred revisions in 9619 PFAs were reported yielding 5-, 10-, 15- and 20-year PFA survivorships of 91.7, 83.3, 74.9 and 66.6 %, respectively, and an annual revision rate of 2.18. Functional outcomes were reported in 2587 PFAs with an overall score of 82.2 % of the maximum score. KSS and Knee Function Score were 87.5 and 81.6 %, respectively. This systematic review showed that fairly good results of PFA survivorship and functional outcomes were reported at short- and midterm follow-up in the setting of isolated patellofemoral osteoarthritis. Heterogeneity existed mainly in prosthesis design and year the cohort started. These results provide a clear overview of the current status of PFA in the setting of isolated patellofemoral osteoarthritis. IV.

Attentional processing of other's facial display of pain: an eye tracking study.

2013-06-01

The present study investigated the role of observer pain catastrophizing and personal pain experience as possible moderators of attention to varying levels of facial pain expression in others. Eye movements were recorded as a direct and continuous index of attention allocation in a sample of 35 undergraduate students while viewing slides presenting picture pairs consisting of a neutral face combined with either a low, moderate, or high expressive pain face. Initial orienting of attention was measured as latency and duration of first fixation to 1 of 2 target images (i.e., neutral face vs pain face). Attentional maintenance was measured by gaze duration. With respect to initial orienting to pain, findings indicated that participants reporting low catastrophizing directed their attention more quickly to pain faces than to neutral faces, with fixation becoming increasingly faster with increasing levels of facial pain expression. In comparison, participants reporting high levels of catastrophizing showed decreased tendency to initially orient to pain faces, fixating equally quickly on neutral and pain faces. Duration of the first fixation revealed no significant effects. With respect to attentional maintenance, participants reporting high catastrophizing and pain intensity demonstrated significantly longer gaze duration for all face types (neutral and pain expression), relative to low catastrophizing counterparts. Finally, independent of catastrophizing, higher reported pain intensity contributed to decreased attentional maintenance to pain faces vs neutral faces. Theoretical implications and further research directions are discussed. Copyright © 2013 International Association for the Study of Pain. Published by Elsevier B.V. All rights reserved.

Most cultures in sub-Saharan Africa subscribe to the belief that the root cause of psychosis is supernatural. Individuals in the community who hold a religiomagical explanatory model of causation have been shown to exhibit more stigmatizing attitudes towards people with psychosis. Self-stigma among individuals with psychosis is less frequently studied. We used a mixed-method approach, consisting of key informant's interviews to elicit information on explanatory models of causation of psychosis and questionnaire assessment of internalized stigma with an adapted version of the Scale for Internalized Stigma of Mental Illness. Twenty-four, 31, and 30 subjects with recent experience of utilizing the service of traditional or faith healers for severe mental disorders in Ibadan (Nigeria), Kumasi (Ghana), and Nairobi (Kenya), respectively, were interviewed. About 44 % (42.1 %) of the Nigerian respondents had a high (severe) level of self-stigma with the respective proportions among Ghanaian and Kenyan respondents being 20.7 and 37.5 %. Compared with 4 out of a total of 12 respondents (33.3 %) who reported low self-stigma reported supernatural attribution, 14 out of 20 respondents (70 %) with the highest level of self-stigma reported supernatural attribution across the three sites. When low scorers ascribed supernatural causation, it was often with a religious focus. There is a greater tendency for persons with high levels of self-stigma than those with low levels to ascribe supernatural attribution to their experience of a severe mental health condition.

Thematic Accuracy Assessment of the 2011 National Land ...

EPA Pesticide Factsheets

Accuracy assessment is a standard protocol of National Land Cover Database (NLCD) mapping. Here we report agreement statistics between map and reference labels for NLCD 2011, which includes land cover for ca. 2001, ca. 2006, and ca. 2011. The two main objectives were assessment of agreement between map and reference labels for the three, single-date NLCD land cover products at Level II and Level I of the classification hierarchy, and agreement for 17 land cover change reporting themes based on Level I classes (e.g., forest loss; forest gain; forest, no change) for three change periods (2001–2006, 2006–2011, and 2001–2011). The single-date overall accuracies were 82%, 83%, and 83% at Level II and 88%, 89%, and 89% at Level I for 2011, 2006, and 2001, respectively. Many class-specific user's accuracies met or exceeded a previously established nominal accuracy benchmark of 85%. Overall accuracies for 2006 and 2001 land cover components of NLCD 2011 were approximately 4% higher (at Level II and Level I) than the overall accuracies for the same components of NLCD 2006. The high Level I overall, user's, and producer's accuracies for the single-date eras in NLCD 2011 did not translate into high class-specific user's and producer's accuracies for many of the 17 change reporting themes. User's accuracies were high for the no change reporting themes, commonly exceeding 85%, but were typically much lower for the reporting themes that represented change. Only forest l

To assess the inequalities in adherence to breast and cervical cancer screening according to educational level. A systematic review was carried out between 2000 and 2013 by querying an electronic database using specific keywords. Studies published in English reporting an estimation of the association between level of education and adherence to breast and/or cervical cancer screening were included in the study. Two different meta-analyses were carried out for adherence to breast and cervical cancer screening, respectively: women with the highest level of education and women with the lowest level of education were compared. The level of heterogeneity was investigated and subgroup analyses were carried out. Of 1231 identified articles, 10 cross-sectional studies were included in the analysis. The meta-analyses showed that women with the highest level of education were more likely to have both screenings with an overall OR=1.61 (95% CI 1.36-1.91; I(2)=71%) for mammography and OR=1.96 (95% CI 1.79-2.16; I(2)=0%) for Pap test, respectively. Stratified meta-analysis for breast cancer screening included only studies that reported guidelines with target age of population ≥50 years and showed a reduction in the level of heterogeneity and an increase of 36% in the adherence (95% CI 1.19-1.55; I(2)=0%). This study confirms and reinforces evidence of inequalities in breast and cervical cancer screening adherence according to educational level. Copyright © 2015 Elsevier Inc. All rights reserved.

Working memory, inhibition, and expressive language are often impaired in ADHD and many children with ADHD have lower IQ-scores than typically developing children. The aim of this study was to test whether IQ-score influences associations between ADHD symptoms and verbal and nonverbal working memory, inhibition, and expressive language, respectively, in a nonclinical sample of preschool children. In all, 1181 children recruited from the Norwegian Mother and Child Cohort Study were clinically assessed at the age of 36 to 46 months. IQ-score and working memory were assessed with subtasks from the Stanford Binet test battery, expressive language was reported by preschool teachers (Child Development Inventory), response inhibition was assessed with a subtask from the NEPSY test, and ADHD symptoms were assessed by parent interview (Preschool Age Psychiatric Assessment). The results showed an interaction between ADHD symptoms and IQ-score on teacher-reported expressive language. In children with below median IQ-score, a larger number of ADHD symptoms were more likely to be accompanied by reports of lower expressive language skills, while the level of ADHD symptoms exerted a smaller effect on reported language skills in children with above median IQ-score. The associations between ADHD symptoms and working memory and response inhibition, respectively, were not influenced by IQ-score. Level of IQ-score affected the relation between ADHD symptoms and teacher-reported expressive language, whereas associations between ADHD symptoms and working memory and response inhibition, respectively, were significant and of similar sizes regardless of IQ-score. Thus, in preschoolers, working memory and response inhibition should be considered during an ADHD assessment regardless of IQ-score, while language skills of young children are especially important to consider when IQ-scores are average or low.

2015-09-01

To compare levels of phosphatidylethanol (PEth) to self-reported alcohol intake among young adult binge drinkers (18-30 years). Abstainers (n = 23), moderate (n = 22), and binge drinkers (n = 58) completed an alcohol consumption questionnaire and the AUDIT. PEth was measured in whole blood and dried blood spots via high-performance liquid chromatography with tandem mass spectrometry. Also measured was mean corpuscular volume (MCV) and gamma glutamyl transpeptidase (GGT). Most subjects were female (65%) and Caucasian (73%). Among binge drinkers, past-month average number of binge episodes was 7.2 ± 4; average duration of binge drinking behavior was 4.3 ± 3 years. AUDIT scores and PEth levels (ng/ml) in whole blood or dried blood spots were significantly (P < 0.001) greater in binge drinkers (13 ± 4, 186 ± 170, and 65 ± 53, respectively) compared to moderate drinkers (6 ± 3, 24 ± 29, and 11 ± 13, respectively) and abstainers (0.6 ± 0.89, 0, and 0, respectively). No differences were found in MCV and GGT among groups. There were significant correlations between whole blood and dried blood spot PEth levels and AUDIT scores (Spearman's r = 0.745 and 0.738, P < 0.0001, respectively), and whole blood and dried blood spot PEth levels were significantly correlated (0.899, P < 0.0001). PEth levels measured in whole blood and dried blood spots were significantly greater in binge drinkers compared to abstainers and moderate drinkers, and these levels were positively correlated with AUDIT scores. © The Author 2015.

Perpetrators and targets of bullying at work: role stress and individual differences.

PubMed

Matthiesen, Stig Berge; Einarsen, Ståle

2007-01-01

A workplace survey study (N = 2215, response rate 47%) revealed that about 16% of the sample may be categorized as either perpetrators (5.4%), provocative victims (2.1%), or as targets of bullying (8.3%). Targets of bullying, provocative victims, and bullies were compared with those 84% who do not report any involvement with respect to bullying at work, self-esteem, aggressive tendencies, prior experiences of bullying, or experiences of role stress. Perpetrators were found to have a higher level of aggression than did the comparison group and the targets. Provocative victims manifested a low level of self-esteem and social competency combined with a high level of aggressiveness. Targets of bullying revealed low levels of self-esteem and social competency. Targets, provocative victims, and perpetrators reported elevated levels of role stress in the form of unclear or conflicting demands and expectations around work tasks and daily work.

U.S. military ground forces report high rates of war-related traumatic stressors, posttraumatic stress disorder (PTSD), and depression following deployment in support of recent armed conflicts in Iraq and Afghanistan. Affected service members do not receive needed mental health services in most cases, and they frequently report stigma and significant structural barriers to mental health services. Improvements in primary care may help address these issues, and evidence supports the effectiveness of a systems-level collaborative care approach. To test the feasibility of systems-level collaborative care for PTSD and depression in military primary care. We named our collaborative care model "Re-Engineering Systems of Primary Care for PTSD and Depression in the Military" (RESPECT-Mil). Key elements of RESPECT-Mil care include universal primary care screening for PTSD and depression, brief standardized primary care diagnostic assessment for those who screen positive, and use of a nurse "care facilitator" to ensure continuity of care for those with unmet depression and PTSD treatment needs. The care facilitator assists primary care providers with follow-up, symptom monitoring, and treatment adjustment and enhances the primary care interface with specialty mental health services. We report assessments of feasibility of RESPECT-Mil implementation in a busy primary care clinic supporting Army units undergoing frequent Iraq, Afghanistan, and other deployments. Thirty primary care providers (family physicians, physician assistants, and nurse practitioners) were trained in the model and in the care of depression and PTSD. The clinic screened 4,159 primary care active duty patient visits: 404 screens (9.7%) were positive for depression, PTSD, or both. Sixty-nine patients participated in collaborative care for 6 weeks or longer, and the majority of these patients experienced clinically important improvement in PTSD and depression. Even although RESPECT-Mil participation was voluntary for providers, only one refused participation. No serious adverse events were noted. Collaborative care is an evidence-based approach to improving the quality of primary care treatment of anxiety and depression. Our version of collaborative care for PTSD and depression, RESPECT-Mil, is feasible, safe, and acceptable to military primary care providers and patients, and participating patients frequently showed clinical improvements. Efforts to implement and evaluate collaborative care approaches for mental disorders in populations at high risk for psychiatric complications of military service are warranted.

The culture of academic medical institutions impacts trainee education, among many other faculty and patient outcomes. Disrespectful behavior by faculty is one of the most challenging and common problems that, left unattended, disrupts healthy work and learning environments. Conversely, a respectful environment facilitates learning, creates a sense of safety, and rewards professionalism. The authors developed surveys and an intervention in an effort to better understand and improve climate concerns among health sciences faculty at the University of California, San Diego (UCSD), a research-intense, public, academic medical center. An online "climate survey" of all UC San Diego health sciences faculty was conducted in 2011-2012. A strategic campaign to address the behavioral issues identified in the initial survey was subsequently launched. In 2015, the climate was re-evaluated in order to assess the effectiveness of the intervention. A total of 478 faculty members (223 women, 235 men, 35 % of faculty) completed the baseline survey, reporting relatively low levels of observed sexual harassment (7 %). However, faculty reported concerning rates of other disruptive behaviors: derogatory comments (29 %), anger outbursts (25 %), and hostile communication (25 %). Women and mid-level faculty were more likely to report these behavioral concerns than men and junior or senior colleagues. Three years after an institutional strategy was initiated, 729 faculty members (50 % of the faculty) completed a follow-up survey. The 2015 survey results indicate significant improvement in numerous climate factors, including overall respectful behaviors, as well as behaviors related to gender. In order to enhance a culture of respect in the learning environment, institutions can effectively engage academic leaders and faculty at all levels to address disruptive behavior and enhance positive climate factors.

The ceramic toximeter as a passive sampler in combination with the CALUX bioassay was utilized as a time-integrated pollution-assessment technique for dioxin-like PCDD/Fs in wastewaters. Toximeters filled with XCARB and enclosed in stainless steel cages were submerged in wastewater of Belbeis drainage-canal and EMAK paper-mill, located in Egypt, for 28 days. Two samplers were removed every week from each site. Extracts from toximeters, from bottom-sediments, and from paper-mill sludge were analyzed by the CALUX. Results showed a regular increase in the amounts of PCDD/Fs trapped by the toximeters as sampling time increased. Time-weighted average concentrations (TWA) of PCDD/Fs in the wastewaters of the drainage-canal and paper-mill were 231 (214-281) and 26 (24.1-32.6) pg-BEQ L-1, respectively. Compared to literature data, this means a high pollution level for the drainage-canal water, while the pollution level in the paper-mill wastewater is similar to that reported for other paper mills. The PCDD/Fs levels in the drainage-canal bottom-sediments and in the paper-mill sludge were 8.3 and 14.6 pg-BEQ g-1 dry-weight, at the lower end of internationally reported values in similar compartments. The sampling rate of the tested toximeters for dissolved PCDD/Fs was about 3.6 mL d-1. Sediment/water partitioning coefficient log Kd of PCDD/Fs in the drainage-canal and the paper-mill was 1.42 and 2.70 respectively. The organic-carbon normalized partition coefficient log Koc was 4.17 and 3.19 respectively, and is lower than the reported values for other sites. PMID:24075528

The purpose of this study was to determine if the amount of physical activity influences airway sensitivity and bronchodilation in healthy subjects across a range of physical activity levels. Thirty healthy subjects (age, 21.9 ± 2.6 years; 13 men/17 women) with normal pulmonary function reported to the laboratory on 2 separate occasions where they were randomized to breathe either hypertonic saline (HS) (nebulized hypertonic saline (25%) for 20 min) or HS followed by 5 deep inspirations (DIs), which has been reported to bronchodilate the airways. Pulmonary function tests (PFTs) were performed prior to both conditions and following the HS breathing or 5 DIs. Moderate to vigorous physical activity (MVPA) level was measured via accelerometer worn for 7 days. Following the HS breathing, forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) significantly decreased from baseline by -11.8% ± 8.4% and -9.3% ± 6.7%, respectively. A 2-segment linear model determined significant relationships between MVPA and percent change in FEV1 (r = 0.50) and FVC (r = 0.55). MVPA above ∼497 and ∼500 min/week for FEV1 and FVC, respectively, resulted in minor additional improvements (p > 0.05) in PFTs following the HS breathing. Following the DIs, FEV1 and FVC decreased (p < 0.05) by -7.3% ± 8.6% and -5.7% ± 5.7%, respectively, from baseline, but were not related (p > 0.05) to MVPA. In conclusion, these data demonstrate that higher MVPA levels attenuated airway sensitivity but not bronchodilation in healthy subjects.

In literature of strategic management, there are three layers of control defined in organizational structures. These layers are strategic, tactical and operational, in which resides senior, medium level and low level managers respectively. In strategic level, institutional strategies are determined according to senior managers' perceived state of organization. In tactical level, this strategy is processed into methods and activities of a business management plan. Operational level embodies actions and functions to sustain specified business management plan. An acknowledged lead organization in Turkish medical area is examined using case study and data mining method in the scope of this paper. The level of decisions regarded in managerial purposes evaluated through chosen organization's business intelligence event logs report. Hence specification of management level importance of medical organizations is made. Case study, data mining and descriptive statistical method of taken case's reports present that positions of "Chief Executive Officer", "Outpatient Center Manager", "General Manager", monitored and analyzed functions of operational level management more frequently than strategic and tactical level. Absence of strategic management decision level research in medical area distinguishes this paper and consequently substantiates its significant contribution.

The results of French intake estimates for 13 food additives prioritized by the methods proposed in the 2001 Report from the European Commission on Dietary Food Additive Intake in the European Union are reported. These 13 additives were selected using the first and second tiers of the three-tier approach. The first tier was based on theoretical food consumption data and the maximum permitted level of additives. The second tier used real individual food consumption data and the maximum permitted level of additives for the substances which exceeded the acceptable daily intakes (ADI) in the first tier. In the third tier reported in this study, intake estimates were calculated for the 13 additives (colours, preservatives, antioxidants, stabilizers, emulsifiers and sweeteners) according to two modelling assumptions corresponding to two different food habit scenarios (assumption 1: consumers consume foods that may or may not contain food additives, and assumption 2: consumers always consume foods that contain additives) when possible. In this approach, real individual food consumption data and the occurrence/use-level of food additives reported by the food industry were used. Overall, the results of the intake estimates are reassuring for the majority of additives studied since the risk of exceeding the ADI was low, except for nitrites, sulfites and annatto, whose ADIs were exceeded by either children or adult consumers or by both populations under one and/or two modelling assumptions. Under the first assumption, the ADI is exceeded for high consumers among adults for nitrites and sulfites (155 and 118.4%, respectively) and among children for nitrites (275%). Under the second assumption, the average nitrites dietary exposure in children exceeds the ADI (146.7%). For high consumers, adults exceed the nitrite and sulfite ADIs (223 and 156.4%, respectively) and children exceed the nitrite, annatto and sulfite ADIs (416.7, 124.6 and 130.6%, respectively).

Luciferase reporter constructs are widely used for analysis of gene regulation when characterizing promoter and enhancer elements. We report that the recently developed codon-modified Renilla luciferase construct included as an internal standard for cotransfection must be used with great caution with respect to the amount of DNA transfected. Also, the dual-luciferase reporter vectors encoding Photinus pyralis firefly or Renilla reniformis luciferase showed a linear increase in dose-response with increasing amounts of transfected DNA, but at higher levels of transfected DNA, a reduction in expressed levels of luciferase activity resulted. In addition, treatment with type I interferon (IFN) was found to significantly reduce levels of P. pyralis firefly and Renilla luciferase activity. In contrast, cells transfected with a green fluorescent protein (GFP) reporter construct showed no significant IFN-associated change. The reduction in luciferase activity resulting from IFN treatment was not due to IFN-mediated cytotoxicity, as no change in cellular propidium iodide (PI) staining was observed by flow cytometry. IFN treatment did not alter the levels of firefly luciferase activity in cell culture supernatants or the luciferase mRNA levels determined by quantitative real-time RT-PCR analysis. Based on these results, it is probable that the IFN-induced reduction in levels of luciferase activity detected in reporter assays occurs via a posttranscriptional mechanism. Thus, it is important to be aware of these complications when using luciferase reporter systems in general or for analyzing cytokine-mediated responsive regulation of target genes, particularly by the type I IFNs.

To investigate the association between self-reported sleep duration and serum vitamin D level in elderly Korean adults. Cross-sectional data analysis. Korean National Health and Nutrition Examination Survey 2010. Noninstitutionalized adults aged 60 to 80 (N = 1,614). The confounding variables were serum 25-hydroxy vitamin D level, age, sex, body mass index, smoking history, alcohol consumption, and self-reported daily sun exposure and sleep duration. Self-reported daily sleep duration was divided into four groups: Q1 (≤4 hours), Q2 (5-6 hours), Q3 (7-8 hours), and Q4 (≥9 hours). Mean serum vitamin D levels of subjects in the Q1, Q2, Q3, and Q4 groups were 44.18, 48.08, 48.83, and 51.78 nmol/L, respectively. On multivariate linear regression analysis, subjects in the Q2 (B = 3.80, 95% confidence interval (CI) = 0.42-7.19), Q3 (B = 4.89, 95% CI = 1.54-8.24), and Q4 (B = 5.18, 95% CI = 0.78-9.58) groups had significantly higher serum vitamin D levels than subjects in the Q1 group. Serum vitamin D level is positively associated with self-reported daily sleep duration in elderly Korean individuals. These results suggest that inadequate sleep duration may be associated with lower vitamin D levels in elderly adults. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

Hand-arm vibration syndrome from exposure to high-pressure hoses.

Cooke, R; House, R; Lawson, I J; Pelmear, P L; Wills, M

2001-09-01

Hand-arm vibration syndrome has been reported in the literature to occur following exposure to vibration from the use of many tools, but to date there have been no case reports of its occurrence in workers who have used high-pressure hoses, alone or with other tools. To remedy this, the case histories of nine subjects (two without mixed exposure) examined in the UK and Canada are presented, together with their severity classified according to the Stockholm scales. Attention is drawn to the need to use multiple diagnostic tests to establish the diagnosis and the need to implement vibration isolation and damping methodologies, as and when feasible, with respect to hose nozzles in order to minimize the hazard. The ultimate goal for tool manufacturers, hygienists and engineers should be to reduce workplace vibration levels to meet national and international guidelines and legislation, including UK Health & Safety Executive guidelines and European Economic Community directives. The respective risk levels are presented, together with vibration measurements on hoses used by some of the cases.

"ADAM' or "EVE'?--a toxicological conundrum.

Cox, D E; Williams, K R

1996-01-12

The 3,4-methylenedioxy ring-substituted amphetamines, including "ADAM' and "EVE', are currently popular drugs of abuse. Adverse reactions are reported in the clinical literature but few fatal cases are documented and little toxicological data is available to guide those determining the cause or manner of death in such cases. We report two deaths presenting in a similar manner and with similar clinical features. Various body fluid samples were analysed for amphetamines by gas chromatography/mass spectrometry. In one case, amphetamine alone was detected at levels of 1.54 mg/l and 1.47 mg/l in postmortem blood and admission serum, respectively. The other involved several 3,4-methylenedioxy ring-substituted amphetamines, namely MDA, MDMA and MDEA, at levels of 0.25 mg/l, 0.43 mg/l and 0.3 mg/l, respectively in postmortem femoral blood and 0.24 mg/l, 0.55 mg/l and 0.49 mg/l in admission blood. The interpretation of these toxicological results and some novel legal issues are discussed.

Nurse teacher stress in Northern Ireland.

Hunter, P; Houghton, D M

1993-08-01

Occupational stress among a 60% sample of all nurse tutors in Northern Ireland was investigated by means of the General Health Questionnaire (GHQ), Maslach Burnout Inventory and a stress questionnaire. Seventy per cent of tutors judged themselves to be worse or much worse than usual on 45% of GHQ items. Significant levels of moderate and high burnout were discovered on the sub-scales of emotional exhaustion and depersonalization, with an almost unanimous (95%) report of high burnout arising out of feelings of lack of personal accomplishment. Male nurse tutors reported more frequent and more intense signs of burnout than their female counterparts at a statistically significant level of difference in emotional exhaustion (P = 0.028 and P = 0.003 respectively) and in depersonalization (P < 0.003 and P = 0.007 respectively). The work stressor most commonly identified by tutors (72%) was that of experiencing too little time to perform their duties to their satisfaction. The most common request for help to alleviate workplace stress (61%) was for more support and appreciation from their seniors.

Specific IgE tests are sometimes difficult to interpret due to structural similarities between certain food and pollen allergens. This may be the reason why concomitant sensitization to peanut and birch pollen is frequently seen. The aim of this study was to investigate reported symptoms to peanut- and birch pollen in relation to sensitization. The data originate from 1928 children in the BAMSE birth cohort. Background factors and clinical parameters were obtained and the levels of IgE antibodies to peanut and birch pollen measured at 4 and 8 years. IgE antibodies to peanut were found in 5.5% and 7.4% of the children at 4 and 8 years, respectively. The IgE antibody levels to peanut were higher in children sensitized to peanut but not birch than in children sensitized to peanut and birch among both 4- and 8-year-olds (P = 0.093 and P = 0.003, respectively). Eight-year-olds sensitized to peanut but not birch, more often reported symptoms to peanut than children sensitized to both peanut and birch pollen (76%vs 46%, P = 0.002). The probability of reported symptoms to peanut increased significantly with increasing IgE levels to peanut, especially in 8-year-olds not sensitized to birch. Children sensitized to both peanut and birch pollen are less likely to report symptoms to peanut than children sensitized to peanut but not to birch pollen at 8 years. This is likely due to cross reactions between birch pollen and peanut and can explain the high sensitization rate to peanut in areas where birch trees are common.

Although HIV stigma has been identified as an important risk factor for HIV transmission risk behaviors, little is known about the contribution of community-level HIV stigma to HIV transmission risk behaviors and self-reported sexually transmitted diseases (STDs) or how gender may modify associations. We pooled data from the 2008 and 2013 Sierra Leone Demographic and Health Surveys. For HIV stigma, we examined HIV stigmatizing attitudes and HIV disclosure concerns at both individual and community levels. Outcomes of HIV transmission risk behaviors were recent condom usage, consistent condom usage, and self-reported STDs. We assessed associations with multivariable logistic regressions. We also analyzed gender as an effect modifier of these associations. Of 34,574 respondents, 24,030 (69.5%) who had heard of HIV were included in this analysis. Community-level HIV stigmatizing attitudes and disclosure concerns were associated with higher odds of self-reported STDs (adjusted odds ratio = 2.07; 95% confidence interval: 1.55 to 2.77; adjusted odds ratio = 2.95; 95% confidence interval: 1.51 to 5.58). Compared with men, community-level HIV stigmatizing attitudes among women were a stronger driver of self-reported STDs (interaction P = 0.07). Gender modified the association between community-level HIV disclosure concerns and both recent and consistent condom usage (interaction P = 0.03 and P = 0.002, respectively). Community-level HIV disclosure concerns among women were observed to be a driver of risky sex and self-reported STDs. This study shows that community-level HIV stigma may be a driver for risky sex and self-reported STDs, particularly among women. Our findings suggest that community-held stigmatizing beliefs and HIV disclosure concerns among women might be important targets for HIV stigma reduction interventions.

In smokers without airflow obstruction, detailed, objective and controlled quantification of the level of physical inactivity in daily life has never been performed. This study aimed to objectively assess the level of physical activity in daily life in adult smokers without airflow obstruction in comparison with matched non-smokers, and to investigate the determinants for daily physical activity in smokers. Sixty smokers (aged 50 (39-54) years) and 50 non-smokers (aged 48 (40-53) years) matched for gender, age, anthropometric characteristics, educational level, employment status and seasons of the year assessment period were cross-sectionally assessed regarding their daily physical activity with a step counter, besides assessment of lung function, functional exercise capacity, quality of life, anxiety, depression, self-reported comorbidities carbon monoxide level, nicotine dependence and smoking habits. When compared with non-smokers, smokers walked less in daily life (7923 ± 3558 vs 9553 ± 3637 steps/day, respectively), presented worse lung function, functional exercise capacity, quality of life, anxiety and depression. Multiple regression analyses identified functional exercise capacity, Borg fatigue, self-reported motivation/physical activity behaviour and cardiac disease as significant determinants of number of steps/day in smokers (partial r(2)  = 0.10, 0.12, 0.16 and 0.05; b = 15, -997, 1207 and -2330 steps/day, respectively; overall fit of the model R(2)  = 0.38; P < 0.001). Adult smokers without airflow obstruction presented reduced level of daily physical activity. Functional exercise capacity, extended fatigue sensation, aspects of motivation/physical activity behaviour and self-reported cardiac disease are significant determinants of physical activity in daily life in smokers. © 2014 The Authors.

Abstract Background  Physicians are increasingly urged to practice shared decision‐making with their patients. Using a cross‐sectional survey, we explored the extent to which Ontario breast cancer specialists report practising shared decision‐making with their patients, their comfort level with this approach, and perceived barriers and facilitators to implementation. Participants and methods  All Ontario surgeons and oncologists (radiation and medical) treating women with early‐stage breast cancer were eligible for this study. Likert scales were used to measure physicians’ comfort level with and self‐reported use of different treatment decision‐making approaches as well as perceived barriers and facilitators to treatment decision‐making with patients. Results  The response rate was 79% for oncologists and 72% for surgeons. More physicians from each specialty (87% of oncologists and 89% of surgeons) expressed high levels of comfort with clinical example 4 (designed to illustrate a shared approach) than with any of the other examples presented (e.g. the informed and paternalistic approach). Similarly, more oncologists and surgeons reported that their usual approach to treatment decision‐making was like example 4 than like any other approach presented (56% of oncologists and 69% of surgeons, respectively). Comfort levels with example 4 for oncologists and surgeons were 31% and 20% higher, respectively, than the reported use of this approach. Lack of time and patient anxiety, patient lack of information and/or misinformation, and patient unwillingness or inability to participate were perceived by a substantial minority of both oncologists and surgeons as barriers to patient involvement in treatment decision‐making. Key facilitators identified included patients’ emotional readiness, support, information and trust in the physician. More research is needed to identify contextual, physician, patient, and interaction factors that will facilitate shared decision‐making in the medical encounter and help both parties create an environment conducive to implementing this approach to the extent desired.

The authors investigated the ability/potencies of 3 microbial volatile organic compounds and a mixture of 5 microbial volatile organic compounds to cause eye and upper respiratory tract irritation (i.e., sensory irritation), with an animal bioassay. The authors estimated potencies by determining the concentration capable of decreasing the respiratory frequency of mice by 50% (i.e., the RD50 value). The RD50 values for 1-octen-3-ol, 3-octanol, and 3-octanone were 182 mg/m3 (35 ppm), 1359 mg/m3 (256 ppm), and 17586 mg/m3 (3360 ppm), respectively. Recommended indoor air levels calculated from the individual RD50 values for 1-octen-3-ol, 3-octanol, and 3-octanone were 100, 1000, and 13000 microg/m3, respectively-values considerably higher than the reported measured indoor air levels for these compounds. The RD50 value for a mixture of 5 microbial volatile organic compounds was also determined and found to be 3.6 times lower than estimated from the fractional concentrations and the respective RD50s of the individual components. The data support the conclusion that a variety of microbial volatile organic compounds may have some synergistic effects for the sensory irritation response, which constrains the interpretation and application of recommended indoor air levels of individual microbial volatile organic compounds. The results also showed that if a particular component of a mixture was much more potent than the other components, it may dominate the sensory irritation effect. With respect to irritation symptoms reported in moldy houses, the results of this study indicate that the contribution of microbial volatile organic compounds to these symptoms seems less than previously supposed.

This study reports cancer-treating institutions' capacity to deliver comprehensive psychosocial support services. Oncology care providers at 60 cancer-treating institutions completed surveys assessing the capacity of their institutions to provide psychosocial care. Capacity was assessed with the Cancer Psychosocial Care Matrix (CPCM) from the National Cancer Institute (NCI). Scores represented individuals' perceptions of their cancer program's performance with respect to 10 fundamental elements of psychosocial care. Among 2134 respondents, 62% reported a mid-level capacity for ≥5 of 10 CPCM items. In comparison with other types of cancer programs (eg, NCI-designated, academic, or comprehensive centers), providers at community cancer programs reported a significantly greater capacity with respect to patient-provider communication, psychosocial needs assessment, and continuity in the delivery of psychosocial care over time. Nurses and primary medical providers reported a significantly lower capacity for linking patients and families with needed psychosocial services within their respective cancer programs. They also reported a significantly higher capacity for conducting follow-up, re-evaluations, and adjustments of psychosocial treatment plans. Cancer programs are performing moderately well in terms of communicating to patients the importance of psychosocial care, identifying patient psychosocial needs, and referring patients and families to psychosocial services. They are doing less well with respect to the provision of that care over time. Findings suggest that gaps in psychosocial service capacity are a function of patient, provider, and system characteristics. These results may be useful in formulating strategies to enhance psychosocial care delivery. Cancer 2016;122:1937-45. © 2016 American Cancer Society. © 2016 American Cancer Society.

The zygoma implant has been an effective option in the short-term management of the atrophic edentulous maxilla. To report on long-term outcomes in the rehabilitation of the atrophic maxilla using zygomatic (ZI) and regular implants (RI). 22 consecutive zygomatic patients in a maintenance program were included. Cumulative survival rate (CSR) of ZI, RI, prostheses, and complications were recorded during, at least, 10 years of loading. Implant mobility was tested using Periotest(®). Sinus health was radiographically and clinically assessed according to Lund-Mackay (L-M) score and Lanza and Kennedy survey, respectively. A satisfaction questionnaire and anatomical measurements were also performed. Patients received 22 prostheses, anchored on 172 implants. Forty-one were ZI. Three RI failed (10 years CSR = 97.71%). Two ZI were partly removed due to perimplant infection (10 years CSR = 95.12%). All patients maintained functional prostheses. One patient fractured framework twice. Loosening or fracturing screws happened in 11 patients. Seven patients fractured occlusal material. Four ZI abutments in two patients were disconnected because of uncomfortable prostheses. Alveolar height at the ZI head level on the right and left sides was 2.64 mm and 2.25 mm, respectively. Mean distance of ZI head center to ridge center, on the right and left sides was 4.54 mm and 5.67 mm, respectively. Mean Periotest values (PTv) of ZI were -4.375 PTv and -4.941 PTv before prostheses placement and after 10 years, respectively. Six patients experienced sinusitis 14-127 months postoperatively. 54.55% of the L-M scores did not present opacification (L-M = 0) in any sinus. Osteomeatal obstruction happened in eight patients (two bilateral). Two (9.09%) were diagnosed with sinusitis. Eighty-four percent reported satisfaction levels above 80%. 31.81% reported maximum satisfaction score (100%). The long-term rehabilitation of the severely atrophic maxillae using ZI is a predictable procedure. © 2012 Wiley Periodicals, Inc.

We hereby report the transformation of deoxynivalenol (DON) and its acetylated derivatives (3-ADON and 15-ADON) by spiking targeted mycotoxins to Fusarium mycotoxin-free flour in the process of making Chinese steamed bread (CSB). The impacts of pH, yeast level, and steaming time on the transformation of 3-ADON to DON were investigated. DON, 3-ADON, and 15-ADON were analyzed by UPLC-MS/MS. Spiked DON was stable throughout the CSB making process. Spiked 3-ADON and 15-ADON were partially deacetylated and transformed to DON during kneading (54.1-60.0% and 59.3-77.5%, respectively), fermentation (64.0-76.9% and 78.2-91.6%, respectively), and steaming (47.2-52.7% and 52.4-61.9%, respectively). The ADONs level increased after steaming compared with their level in the previous step. The pH level and steaming duration significantly (P<0.05) affected the conversion of 3-ADON during the CSB making process. Briefly, alkaline conditions and short steaming times favored the deacetylation of 3-ADON. The level of yeast did not remarkably (P<0.05) alter the transformation between ADONs and DON.

Background Epidermal growth factor receptor tyrosine kinase inhibitors significantly prolong the progression-free survival of patients with non-squamous non-small cell lung cancer (NSCLC). However, most patients develop tumor regrowth and their prognosis remains poor. A new treatment strategy for NSCLC harboring EGFR mutation is therefore necessary. Methods In phase I, eligible patients were administered oral erlotinib daily and intravenous pemetrexed, carboplatin, and bevacizumab every 3 weeks for four cycles with maintenance of pemetrexed and bevacizumab until progressive disease was observed. The dose of erlotinib was 100 mg for dose level 1 and 150 mg for dose level 2. The doses of pemetrexed, carboplatin, and bevacizumab were fixed at 500 mg/m2, area under the concentration–time curve of 6 mg/mL · min, and 15 mg/kg, respectively. The dose-limiting toxicities were grade 3/4 neutropenia with fever or infection, grade 4 leukopenia lasting for ≥7 days, grade 4 thrombocytopenia, grade 3/4 uncontrollable nonhematological toxicity, and delayed administration of the subsequent cycle by >2 weeks because of adverse events. Results Six patients were enrolled in phase I (dose level 1, n = 3; dose level 2, n = 3). During the induction phase, grade 3 neutropenia without fever was observed in one patient at dose level 1 and two patients at dose level 2. Grade 3 anemia was reported in one patient at dose level 1 and grade 3 thrombocytopenia was reported in two patients at dose level 1 and dose level 2, respectively. Conclusion Four-drug combination therapy is a feasible and promising. PMID:28740574

The integration of object levels and their content: a theory of global/local processing and related hemispheric differences.

PubMed

Hübner, Ronald; Volberg, Gregor

2005-06-01

This article presents and tests the authors' integration hypothesis of global/local processing, which proposes that at early stages of processing, the identities of global and local units of a hierarchical stimulus are represented separately from information about their respective levels and that, therefore, identity and level information have to be integrated at later stages. It further states that the cerebral hemispheres differ in their capacities for these binding processes. Three experiments are reported in which the integration hypothesis was tested. Participants had to identify a letter at a prespecified level with the viewing duration restricted by a mask. False reporting of the letter at the nontarget level was predicted to occur more often when the integration of identity and level could fail. This was the case. Moreover, visual-field effects occurred, as expected. Finally, a multinomial model was constructed and fitted to the data. ((c) 2005 APA, all rights reserved).

Fast-track (FT) postoperative protocol in oncological patients after major abdominal surgery reduces complications and length of postoperative stay compared to the conventional (CON) protocol. However, stress and pain responses have not been compared between the two protocols. To compare stress, pain, and related neuropeptidic responses (adrenocorticotropic hormone [ACTH], cortisol, and neuropeptide Y [NPY]) between FT and CON protocols. A clinical trial with repeated measurements was conducted (May 2012 to May 2014) with a sample of 63 hepatectomized or pancreatectomized patients randomized into two groups: FT ( n = 29) or CON ( n = 34). Demographic and clinical data were collected, and pain (Visual Analog Scale [VAS] and Behavioral Pain Scale [BPS]) and stress responses (3 self-report questions) assessed. NPY, ACTH, and cortisol plasma levels were measured at T1 = day of admission, T2 = day of surgery, and T3 = prior to discharge. ACTH T1 and ACTH T2 levels were positively correlated with self-reported stress levels (ρ = .43 and ρ = .45, respectively, p < .05) in the FT group. NPY levels in the FT group were higher than those in the CON group at all time points ( p ≤ .004); this difference remained significant after adjusting for T1 levels through analysis of covariance for age, gender, and body mass index ( F = .003, F = .149, F = .015, respectively, p > .05). Neuropeptidic levels were higher in the FT group. Future research should evaluate this association further, as these biomarkers might serve as objective indicators of postoperative pain and stress.

In this study, the impact levels in environmental impact assessment (EIA) reports of 10 incinerator plants were quantified and discussed. The relationship between the quantified impact levels and the plant scale factors of BeiTou, LiZe, BaLi, LuTsao, RenWu, PingTung, SiJhou and HsinChu were constructed, and the impact levels of the GangShan (GS) and YongKong (YK) plants were predicted using grey model GM (1, N). Finally, the effects of plant scale factors on impact levels were evaluated using grey model GM (1, N) too. According to the predicted results of GM, the relative errors of topography/geology/soil, air quality, hydrology/water quality, solid waste, noise, terrestrial fauna/flora, aquatic fauna/flora and traffic in the GS plant were 17%, 14%, 15%, 17%, 75%, 16%, 13%, and 37%, respectively. The relative errors of the same environmental items in the YK plant were 1%, 18%, 10%, 40%, 37%, 3%, 25% and 33%, respectively. According to GM (1, N), design capacity (DC) and heat value (HV) were the plant scale factors that affected the impact levels significantly in each environmental item, and thus were the most significant plant scale factors. GM (1, N) was effective in predicting the environmental impact and analyzing the reasonableness of the impact. If there is an EIA for a new incinerator plant to be reviewed in the future, the official committee of the Taiwan EPA could review the reasonableness of impact levels in EIA reports quickly.

Functional hemispheric asymmetries of global/local processing mirrored by the steady-state visual evoked potential.

PubMed

Martens, Ulla; Hübner, Ronald

2013-03-01

While hemispheric differences in global/local processing have been reported by various studies, it is still under dispute at which processing stage they occur. Primarily, it was assumed that these asymmetries originate from an early perceptual stage. Instead, the content-level binding theory (Hübner & Volberg, 2005) suggests that the hemispheres differ at a later stage at which the stimulus information is bound to its respective level. The present study tested this assumption by means of steady-state evoked potentials (SSVEPs). In particular, we presented hierarchical letters flickering at 12Hz while participants categorised the letters at a pre- cued level (global or local). The information at the two levels could be congruent or incongruent with respect to the required response. Since content-binding is only necessary if there is a response conflict, asymmetric hemispheric processing should be observed only for incongruent stimuli. Indeed, our results show that the cue and congruent stimuli elicited equal SSVEP global/local effects in both hemispheres. In contrast, incongruent stimuli elicited lower SSVEP amplitudes for a local than for a global target level at left posterior electrodes, whereas a reversed pattern was seen at right hemispheric electrodes. These findings provide further evidence for a level-specific hemispheric advantage with respect to content-level binding. Moreover, the fact that the SSVEP is sensitive to these processes offers the possibility to separately track global and local processing by presenting both level contents with different frequencies.

Acoustic velocity measurements were taken using Particle Image Velocimetry (PIV) in a Normal Incidence Tube configuration at various frequency, phase, and amplitude levels. This report presents the results of the PIV analysis and data reduction portions of the test and details the processing that was done. Estimates of lower measurement sensitivity levels were determined based on PIV image quality, correlation, and noise level parameters used in the test. Comparison of measurements with linear acoustic theory are presented. The onset of nonlinear, harmonic frequency acoustic levels were also studied for various decibel and frequency levels ranging from 90 to 132 dB and 500 to 3000 Hz, respectively.

Suicidal behaviors and depression are prevalent phenomena among adolescents, and are considered a public health problem. To determine the prevalence of depressive symptoms and suicidal behaviors and the relationship between both phenomena, in a representative sample of students from ninth grade in Santiago, Chile. We recruited a probability sample of 2,597 adolescents who answered a questionnaire with questions about suicidal behavior and the Beck Depression Inventory (BDI-II). The lifetime prevalence of suicidal ideation and planning was 21 and 14%, respectively. The prevalence for the past two weeks was 6.7 and 4.4% for suicidal ideation and planning, respectively. Autolytic behaviors, once in lifetime and in the past week were referred by 26 and 4% of respondents, respectively. In one third of these, self-harm coincided with recent suicide ideation or planning. All levels of suicidal behavior were more frequently reported by women. Clinically significant depressive symptoms were present in 23.5% of adolescents. Females doubled male rates. Severe depressive symptoms were present in 9.4% of the sample. A higher level of suicidal behavior correlated with more severe forms of depression. Sixty percent of adolescents who reported recent self-harm, had clinically relevant depressive symptoms. Two thirds of them had severe symptoms. Suicidal behavior in Chilean adolescents is prevalent, and there is an association between this behavior and the level of depression. The school is a good place to identify and develop preventive measures for teenagers.

The determination of 6-, 8-, 10-gingerol, and 6-shogaol in dried ginger (Zingiber officinale) and in the dried aqueous extract of ginger is reported. This is the first study to report a validated method for the determination of these 4 analytes. Several extraction solvents and methods were examined, and the optimum combination was determined. The samples were extracted at room temperature by sonication with methanol, and the extract was analyzed by liquid chromatography with photodiode array detection. A C18 column was used with a water-acetonitrile gradient mobile phase. Quantification was at 200 nm. The levels of 6-, 8-, 10-gingerol, and 6-shogaol in the raw herb were 9.3, 1.6, 2.3, and 2.3 mglg, respectively. The levels of gingerols found in the dried aqueous extract were between 5 and 16 times lower than those in the raw herb, but the level of 6-shogaol was higher. Analyte identity was confirmed by negative-ion electrospray ionization tandem mass spectrometry, in which 2 daughter ions were obtained for each analyte. The average recovery was 97% with a relative standard deviation of <8%. The limits of detection for 6-, 8-, 10-gingerol, and 6-shogaol in the raw herb were 0.22, 0.04, 0.09, and 0.07 mglg, respectively, and in the dried aqueous extract, 0.11, 0.02, 0.02, and 0.14 mg/g, respectively.

A national survey of oral health of children and adolescents was carried out in the Republic of Ireland (RoI) in 2001/2002. To compare the prevalence of caries between child and adolescent residents in fluoridated and non-fluoridated communities in the RoI whilst controlling for disadvantage. To compare caries levels amongst disadvantaged and non-disadvantaged groups with and without water fluoridation. To report the changes in caries levels between the 1960s and 2002 in RoI. To report the changes in dental fluorosis levels between 1984 and 2002. Cross sectional oral health survey of a representative, random, stratified sample of 17,851 5-, 8-, 12- and 15-year-old children and adolescents in RoI. WHO examination criteria with the addition of visible, non-cavitated dentine caries were used for recording caries. Fluorosis was measured using Dean's Index. In the RoI the mean dmft/DMFT scores for 5-, 8-, 12-, and 15-year-olds were 1.2, 0.3, 1.1 and 2.3. For those with domestic water fluoridation since birth the scores were 1.0, 0.3, 1.1 and 2.1 respectively. In non-fluoridated areas of RoI the mean dmft/DMFT scores for 5-, 8-, 12-, and 15-year-olds was 1.7, 0.3, 1.3 and 3.2, respectively. For 5-, 12- and 15-year-old age groups dental caries levels were lower amongst children with fluoridated domestic water supplies (all p<0.0001). The prevalence of dental fluorosis has increased in RoI since 1984. 23% and 36% of 8- and 15-year olds respectively in fluoridated areas had Dean's Index scores at the questionable or greater level in 2002, compared with 6% and 5% respectively in 1984. Caries levels are lower among children with fluoridated domestic water supplies. Decay levels are much lower in 2002 than they were in 1984 and in the 1960s. The oral health of the less well off is worse than that of the rest of the population. The prevalence of dental fluorosis is higher amongst children and adolescents with fluoridated water supplies. Comparisons with 1984 data show an increase in the prevalence of fluorosis since that time.

This study explores the association between ethnicity and poor self-reported health and psychological distress, sleeping difficulties, and use of psychotropic drugs among immigrant Kurdish men and native Swedish men, based on data from the first Swedish National Survey of Immigrants and the Swedish Level-of-Living Surveys collected in 1996 by Statistics Sweden. The age-adjusted odds of poor self-reported health and sleeping difficulties among Kurdish men was about 3.5 times higher than among Swedish men. The odds ratio decreased to 2.1 and 2.7 respectively in a model adjusted for age and the other explanatory variables. Yearning for the home country, perceived discrimination and unemployment in the host country seem to be possible explanations for the higher levels of distress among Kurdish immigrants to Sweden.

The effect of different overrun levels on the sensory acceptance and survival of probiotic bacteria in ice cream was investigated. Vanilla ice creams supplemented with Lactobacillus acidophilus were processed with overruns of 45%, 60%, and 90%. Viable probiotic bacterial counts and sensory acceptance were assessed. All the ice creams presented a minimum count of 6 log CFU/g at the end of 60 d of frozen storage. However, higher overrun levels negatively influenced cell viability, being reported a decrease of 2 log CFU/g for the 90% overrun treatment. In addition, it was not reported an influence about acceptability with respect to appearance, aroma, and taste of the ice creams (P > 0.05). Overall, the results suggest that lower overrun levels should be adopted during the manufacture of ice cream in order to maintain its probiotic status through the shelf life. © 2012 Institute of Food Technologists®

Objective: To evaluate the accuracy of human brucellosis diagnosis and reporting in medical institutions in Shanxi province, and understand the performance of clinical doctors to diagnose human brucellosis according to diagnostic criteria. Methods: Field investigation was conducted in 6 medical institutions in the key areas of human brucellosis in Shanxi province. The diagnosis data of the reported brucellosis cases in 2015 were collected and reviewed retrospectively for the evaluation of the diagnosis accuracy with systematic sampling method. The database was established with Excel 2010 and the descriptive analysis and statistical test were conducted with software R 3.3.2. Results: The diagnosis consistent rate of the 377 brucellosis cases reviewed was 70.8% (267/377), the diagnosis consistent rates in medical institutions at city-level and country-level were 77.0% (127/165) and 66.0% (140/212) respectively, the differences had significance ( χ (2)=5.4, P =0.02). Among the reviewed cases, the diagnosis consistent rate of laboratory diagnosis and clinical diagnosis were 87.1% (256/294) and 13.3% (11/83) respectively, and the differences had significance ( χ (2)=170.7, P <0.001). Among the 21 investigated clinical doctors, the numbers of the doctors who correctly diagnosed the suspected cases, probable cases and lab-confirmed cases were only 3, 0 and 8 respectively. All of the clinical doctors knew that it is necessary to report the brucellosis cases within 24 hours after diagnosis. Conclusion: The accuracy of human brucellosis diagnosis in key areas of human brucellosis in Shanxi was low, and the performance of the clinical doctors to diagnose human brucellosis according to diagnostic and case classification criteria was unsatisfied.

Cardiologists' work distress has been seldom studied. The ItAliaN cardiologists' Undetected distress Study survey was designed to assess prevalence of work distress and satisfaction, and to gain insight into associations among these constructs and socio-demographics and job description. We invited members of our national cardiological society (Associazione Nazionale Medici Cardiologi Ospedalieri) to participate in an anonymous, self-report, exclusively web-based survey, posted on the Associazione Nazionale Medici Cardiologi Ospedalieri website. ItAliaN cardiologists' Undetected distress Study included socio-demographics, job description and a 15-item questionnaire on job-related distress and work satisfaction. Of 7393 invited cardiologists, 1064 completed the survey. Organizational problems and worries about medico-legal controversies were reported by 71% and 49% of participants, respectively; over one-third reported loss of enthusiasm, helplessness, work-life imbalance and lack of control over work. Conversely, 86% felt competent at work, 67% rewarded by the moral/human meaning of their work and 52% satisfied with their professional fulfilment. Factor analysis revealed a meaningful underlying structure including four factors: job strain, positive meaning, emotional fatigue and relational difficulties. Relational difficulties were more frequent in cardiologists working in primary-level than in secondary and tertiary care hospitals (P = 0.017 and P = 0.013, respectively). Interventional cardiologists reported higher positive meaning than those in the clinical inpatients area and outpatient diagnostic settings (P = 0.007 and P = 0.025, respectively) and lower emotional fatigue than subjects in the clinical inpatients area (P = 0.0005). Cardiologists' work distress should be interpreted integrating job-related negative aspects with a reappraisal of protective personal and relational resources, which should be fostered to promote physicians' wellbeing at the individual, collective and organizational levels.

Diabetes mellitus is likely to have a major effect on vision, and adequate knowledge of its ocular manifestations is of substantial importance to diabetic patients. The study aimed to assess the ocular knowledge and practices among Type 2 diabetic patients of Bangladesh. This cross-sectional study included 122 diabetic patients from the outpatient department (OPD) of the apex diabetic healthcare hospital of the country under the sponsorship of the Diabetic Association of Bangladesh (BIRDEM). A questionnaire was used for collecting data on knowledge on and practices relating to diabetes mellitus with particular emphasis on ocular issues. A predefined score was used for categorizing levels of knowledge and practices as poor, average, and good. Of the 122 respondents, 63%, 55%, 40%, 44%, and 30% reported, blindness, retinopathy, cataracts, glaucoma, and double vision respectively, as complications of diabetes mellitus. About 50% were aware of the need for eye screening for people with the complications. Only 8% monitored their blood glucose levels daily, 15% monitored weekly, and 10% reported checking their blood pressure daily and 43% took their medications as prescribed. The level of diabetic knowledge was poor, moderate and good, respectively, among 24%, 56%, and 20% of the respondents, whereas the practice standards showed that 47%, 31%, and 22% had poor, average, and good levels respectively. The knowledge score was significantly associated with the practice score (r = 0.460, p = 0.001). The results indicate that the ocular knowledge and practices among diabetic patients attending a tertiary-care hospital in Bangladesh is average. Health and eye-care practitioners need to expand diabetic health education and promotion among diabetic patients.

This study investigates the association between political trust (an aspect of institutional trust) in the Riksdag (the national parliament in Sweden) and self-reported psychological health, taking generalized (horizontal) trust in other people into account. The 2004 public health survey in Skåne in Southern Sweden is a cross-sectional postal questionnaire study that was answered by 27,757 respondents aged 18-80 yielding a 59% response rate. A logistic regression model was used to investigate the associations between political trust and self-reported psychological health adjusting for possible confounders (age, country of origin, education, economic stress and generalized trust in other people i.e. horizontal trust). We found that 13.0% of the men and 18.9% of the women reported poor psychological health. A total of 17.3% and 11.6% of the male and female respondents, respectively, reported that they had no trust at all in the national parliament, and another 38.2% and 36.2%, respectively, reported that their political trust was not particularly high. Respondents in younger age groups, born abroad, with high education, high levels of economic stress, low horizontal trust and low political trust had significantly higher levels of self-reported poor psychological health. There was a significant association between low political trust and low horizontal trust. After adjustments for age, country of origin, education and economic stress, the inclusion of horizontal trust reduced the odds ratios of self-reported poor psychological health in the "no political trust at all" category compared to the "very high political trust" category from 1.6 to 1.4 among men and from 1.7 to 1.4 among women. It is concluded that low political trust in the Riksdag seems to be significantly and positively associated with poor mental health.

Two cases of tetany in the horse are reported. The two patients were thoroughbreds. One was eight and the other thirteen years old. The mares were in heat and were brought to the service (stud) station to be mated. Both patients were nursing a foal. One was a four-week-old foal and the other was seven weeks old. The calcium level of the serum had dropped in the two patients, to 4.0 mg and 5.4 per ml. respectively. The magnesium level was 1.0 mg and 1.9 mg per 100 ml. respectively. The animals responded satisfactorily to intravenous infusion of calcium borogluconate and magnesium chloride. One of the mares was also give 10 1. of physiological saline a few times.

Although the seroprevalence of Toxoplasma gondii, Neospora caninum, Chlamydia abortus and bovine viral diarrhea virus infection in cattle have been reported in some areas in China, most of them were conducted with small number of cattle samples and very limited districts and neglected the assessment of herd management factors associated with herd-level prevalence of these pathogen infections. Thus, from September 2013 to December 2014, a large-scale seroprevalence study was conducted to determine the animal-level and herd-level seroprevalence and identify herd-level risk factors associated with these pathogen infections in 4487 cattle from 134 herds in five provinces (Heilongjiang, Jilin, Liaoning, Shandong, Hebei) and Inner Mongolia Autonomous Region of China. At animal level, the true prevalence of antibodies against T. gondii, N. caninum, C. abortus and bovine viral diarrhoea virus (BVDV) was 10.48, 17.14, 11.92 and 50.10%, respectively. At herd level, the true prevalence of antibodies against T. gondii, N. caninum, C. abortus and BVDV was 27.16, 29.10, 37.31 and 40.30%, respectively. Multivariate analysis of these characteristics showed that source of water and presence of felids were significantly associated with T. gondii infection in the studied cattle herds. Source of water was significantly associated with N. caninum infection in the studied cattle herds. While herd size and management system were significantly associated with BVDV infection in the studied cattle herds, this is the first report of herd-level prevalence and associated risk factors of T. gondii, N. caninum, C. abortus and BVDV infection in cattle in China.

Peripheral artery disease (PAD) typically refers to lower limb vessel ischemia caused by atherosclerotic stenosis of lower extremity arteries. IL18 is a pleiotropic pro-inflammatory cytokine reported to function as an inflammatory biomarker in cardiovascular diseases. IL18 activity is balanced by high-affinity naturally occurring IL18-binding protein (IL18BP). This study aimed to determine whether IL18, IL18 BP mRNA levels and -137 G/C (rs187238) polymorphism, which was previously associated with IL18 gene transcriptional activity, were associated with PAD etiology. IL18, IL18BP mRNA levels from peripheral blood mononuclear cells and -137 G/C (rs187238) polymorphism were determined by quantitative real-time polymerase chain reaction (qRT-PCR) and RT-PCR, respectively, in 55 PAD patients (26 aorta-iliac, 29 femoro-popliteal) and 61 disease-free controls. IL18 mRNA levels were increased in PAD patients compared with healthy controls (p = 0.09); however, did not reach a statistical significant level, also did not significantly differ between aorta-iliac and femoro-popliteal occlusive PAD subgroups (p = 0.285). However, IL18BP mRNA levels were significantly lower in PAD group compared with controls (p < 0.001). Genotype frequencies of rs187238 polymorphism did not significantly differ between PAD patients and controls (p = 0.385). IL18 mRNA levels were significantly correlated with triglycerides and LDL cholesterol levels in PAD patients (p = 0.003, p = 0.014, respectively). HDL cholesterol levels were negatively correlated with IL18 mRNA levels in controls (p = 0.05). This report is a preliminary study to show an association between IL18, IL18BP mRNA levels and PAD and suggests that the IL18 gene may have a significant relationship with triglyceride and LDL cholesterol levels in PAD patients.

BACKGROUND—Somatisation is common among adolescents.
AIMS—To study factors predicting somatisation later in adulthood.
METHODS—Self report questionnaires were administered at baseline examination in 1990 to students (mean age 16.8 years) in schools, and by mail five years later. Results are based on the 615 subjects with no serious disease or injury at baseline.
RESULTS—Regression analyses showed that in men the level of somatic symptoms in 1995 was significantly predicted by the respective level in 1990 and by relief smoking. In women, the level of somatic symptoms in 1995 was significantly predicted by the respective level in 1990, self esteem, and the number of negative life events in 1990. After exclusion of cases with a long standing disease in 1995, the multivariate results remained materially similar except that self esteem was no longer significant among women.
CONCLUSION—These findings may help in early identification of adolescents with somatisation persisting into early adulthood.

Investigation of mRNA quadruplex formation in Escherichia coli.

PubMed

Wieland, Markus; Hartig, Jörg S

2009-01-01

The protocol presented here allows for the investigation of the formation of unusual nucleic acid structures in the 5'-untranslated region (UTR) of bacteria by correlating gene expression levels to the in vitro stability of the respective structure. In particular, we describe the introduction of G-quadruplex forming sequences close to the ribosome-binding site (RBS) on the mRNA of a reporter gene and the subsequent read-out of the expression levels. Insertion of a stable secondary structure results in the cloaking of RBS and eventually reduced gene expression levels. The structures and stability of the introduced sequences are further characterized by circular dichroism (CD) spectroscopy and thermal melting experiments. The extent of inhibition is then correlated to the stability of the respective quadruplex structure, allowing judgement of whether factors other than thermodynamic stability affect the formation of a given quadruplex sequence in vivo. Measuring gene expression levels takes 2 d including cloning; CD experiments take 5 hours per experiment.

Assess relationships between oldest-old (minimum 86 years) patients' perceived social support to their own and their spousal caregivers' hope through application of the actor-partner interdependence model (APIM). 58 dyads of patients and their spousal caregivers completed standardized self-report measures of depression, distress, hope and social support. Patients presented high distress levels. Among patients and spouses, perceived social support was positively correlated to their own level of hope (β = 0.44, p < 0.0001; β = 0.56, p < 0.0001, respectively) and negatively correlated to the other's level of hope (β = -0.25, p < 0.024; β = -0.44, p < 0.0001, respectively). The actor-partner interdependence model was found to be adequate for describing relationships between social support and hope among dyads of oldest-old patients and their spousal caregivers. Patients and caregiver seem to utilize social support to enhance hope.

1977-01-01

Phenytoin elimination is a saturable process obeying Michaelis-Menten kinetics. Plasma phenytoin levels are not related linearly to dose, and small changes in enzyme activity produced by concurrent drug therapy could alter plasma levels. Two cases of phenytoin intoxication associated with simultaneous administration of diazepam are reported. Intravenous phenytoin infusions were given and the apparent Km and Vmax computed from the resulting plasma phenytoin levels. In one case `Km' and `Vmax' were 0.8 μmol/1 and 1.3 μmol/1/hour respectively during concurrent diazepam administration, and 50.3 μmol/1 and 4.4 μmol/1/hour after discontinuation of diazepam. In the second case phenytoin infusion with diazepam gave `Km' and `Vmax' values of 0.012 μmol/1 and 0.95 μmol/1/hour. Without diazepam these were 28.8 μmol/1 and 0.92 μmol/1/hour respectively.

Two studies explored the extent to which dispositions influence the attributions individuals make about the type of conflict they experience. Traits from the Five-Factor Model of personality (FFM) were linked to the tendency to experience task-and relationship-oriented conflict. Results provide some support for the idea that individuals have stable tendencies in the attributions they make about their conflict experiences across time, partners, and situations. Agreeableness and openness were related to reports of relationship conflict at the individual level. However, the strongest effects of personality on conflict attributions were found in the analysis of dyads. This analysis revealed that partner levels of extraversion and conscientiousness were associated with individuals' tendencies to report relationship conflict. Moreover, mean levels of extraversion and conscientiousness in a pair were associated with reports of relationship conflict. Differences between partners in extraversion were associated with more frequent conflict and a greater likelihood of reporting task-related conflict. Implications of these findings with respect to the role of personality in interpersonal relationships are discussed. Finally, these studies provide confirmatory evidence that conflict attributions have a meaningful impact on relationship satisfaction.

The purpose of this investigation is to determine the proportion of sports medicine studies that are labeled as Level I Evidence in 5 journals and compare the quality of surgical and nonsurgical studies using simple quality assessment tools (Consolidated Standards of Reporting Trials [CONSORT] and Jadad). By use of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines over the prior 2 years in the top 5 (citation and impact factor based) sports medicine journals, only Level I Evidence studies were eligible for inclusion and were analyzed. All study types (therapeutic, prognostic, diagnostic, and economic) were analyzed. Study quality was assessed with the level of evidence, Jadad score, and CONSORT 2010 guidelines. Study demographic data were compared among journals and between surgical and nonsurgical studies by use of χ(2), 1-way analysis of variance, and 2-sample Z tests. We analyzed 190 Level I Evidence studies (10% of eligible studies) (119 randomized controlled trials [RCTs]). Therapeutic, nonsurgical, single-center studies from the United States were the most common studies published. Sixty-two percent of studies reported a financial conflict of interest. The knee was the most common body part studied, and track-and-field/endurance sports were the most common sports analyzed. Significant differences (P < .05) were shown in Jadad and CONSORT scores among the journals reviewed. Overall, the Jadad and CONSORT scores were 2.71 and 77%, respectively. No differences (P > .05) were shown among journals based on the proportion of Level I studies or appropriate randomization. Significant strengths and limitations of RCTs were identified. This study showed that Level I Evidence and RCTs comprise 10% and 6% of contemporary sports medicine literature, respectively. Therapeutic, nonsurgical, single-center studies are the most common publications with Level I Evidence. Significant differences across sports medicine journals were found in study quality. Surgical studies appropriately described randomization, blinding, and patient enrollment significantly more than nonsurgical studies. Level I, systematic review of Level I studies.

This study sought to ascertain whether disagreement between patients and physicians on the patients' health status varies according to patients' education level. INTERMEDE is a cross-sectional multicentre study. Data were collected from both patients and doctors via pre- and post consultation questionnaires at the GP's office over a two-week period in October 2007 in 3 regions of France. The sample consists of 585 eligible patients (61% women) and 27 GPs. A significant association between agreement/disagreement between GP and patient on the patient's health status and patient's education level was observed: 75% of patients with a high education level agreed with their GP compared to 50% of patients with a low level of education. Patients and GPs disagreed where patients with the lowest education level said that their health was worse relative to their doctor's evaluation 37% of the time, versus 16% and 14% for those with a medium or high education level respectively. A multilevel multivariate analysis revealed that patients with a low educational level and medium educational level respectively were at higher risk of being overestimated by GP's in respect of self-reported health even if controlling for confounders. These findings suggest that people with a lower education level who consider themselves to have poor health are less reliably identified as such in the primary care system. This could potentially result in lack of advice and treatment for these patients and ultimately the maintenance of health inequalities. Crown Copyright © 2011. Published by Elsevier Ltd.

A retrospective analysis. The aim of this study was to quantify improvements in Visual Analogue Scale (VAS) neck and arm pain, Neck Disability Index (NDI), and Short Form-12 (SF-12) Mental (MCS) and Physical (PCS) Composite scores following an anterior cervical discectomy and fusion (ACDF). ACDF is evaluated with patient-reported outcomes. However, the extent to which these outcomes improve following ACDF remains poorly defined. A surgical registry of patients who underwent primary, one- or two-level ACDF during 2013 to 2015 was reviewed. Comparisons of VAS neck and arm, NDI, and SF-12 MCS and PCS scores were performed using paired t tests from preoperative to each postoperative time point. Analysis of variance (ANOVA) was used to estimate the reduction in neck and arm pain over the first postoperative year. Subgroup analyses were performed for patients with predominant neck (pNP) or arm (pAP) pain, as well as for one- versus two-level ACDF. Eighty-nine patients were identified. VAS neck and arm, NDI, and SF-12 PCS improved from preoperative scores at all postoperative time points (P < 0.05 for each). Across the first postoperative year, patients reported a 2.7-point (44.2%) reduction in neck and a 3.1-point (54.0%) reduction in arm pain (P < 0.05 for each). Sixty-one patients with pNP and 28 patients with pAP reported reductions in neck and arm pain over the first 6 months and 12 weeks postoperatively, respectively (P < 0.05 for each). Patients who underwent one-level ACDFs experienced a 47.2% reduction in neck pain and 55.1% reduction in arm pain over the first postoperative year (P < 0.05 for each), while those undergoing two-level ACDF experienced 39.7% and 49.2% for neck and arm, respectively (P < 0.05 for each). This study suggests that patients experience significant improvements in neck and arm pain following ACDF regardless of presenting symptom. In addition, patients undergoing one-level ACDF report greater reductions in neck and arm pain than patients undergoing two-level fusion. 4.

The U.S. Geological Survey and the Idaho Department of Water Resources, in response to a request from the U.S. Department of Energy, sampled 19 sites as part of a long-term project to monitor water quality of the Snake River Plain aquifer from the southern boundary of the Idaho National Engineering Laboratory to the Hagerman area. Water samples were collected and analyzed for selected radionuclides, stable isotopes, inorganic constituents, and organic compounds. The samples were collected from seven irrigation wells, four domestic wells, two springs, one stock well, three dairy wells, one observation well, and one commercial well. Two quality assurance samples also were collected and analyzed. None of the radionuclides, inorganic constituents, or organic compounds exceeded the established maximum contaminant levels for drinking water. Most of the radionuclide and inorganic constituent concen- trations exceeded their respective laboratory reporting levels. All samples analyzed for surfactants and dissolved organic carbon had concentrations that exceeded their reporting level. Ethylbenzene concentrations exceeded the reporting level in one water sample.

Here, we report the ro-vibrational spectrum of the ν 3(e') band of the methyl radical (CH 3) solvated in superfluid 4He nanodroplets. Five allowed transitions produce population in the N K = 0 0, 1 1, 1 0, 2 2 and 2 0 rotational levels. The observed transitions exhibit variable Lorentzian line shapes, consistent with state specific homogeneous broadening effects. Population relaxation of the 00 and 11 levels is only allowed through vibrationally inelastic decay channels, and the PP 1(1) and RR 0(0) transitions accessing these levels have 4.12(1) and 4.66(1) GHz full-width at half-maximum line widths, respectively. The linemore » widths of the PR 1(1) and RR 1(1) transitions are comparatively broader (8.6(1) and 57.0(6) GHz, respectively), consistent with rotational relaxation of the 2 0 and 2 2 levels within the vibrationally excited manifold. The nuclear spin symmetry allowed rotational relaxation channel for the excited 1 0 level has an energy difference similar to those associated with the 2 0 and 2 2 levels. However, the PQ 1(1) transition that accesses the 1 0 level is 2.3 and 15.1 times narrower than the PR 1(1) and RR 1(1) lines, respectively. The relative line widths of these transitions are rationalized in terms of the anisotropy in the He-CH 3 potential energy surface, which couples the molecule rotation to the collective modes of the droplet.« less

The aim of this study was to examine the levels of serum 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and evaluate their association with age, body mass index, smoking, military record-based variables, and estimated exposure to Agent Orange in Korean Vietnam veterans. Serum levels of TCDD were analyzed in 102 Vietnam veterans. Information on age, body mass index, and smoking status were obtained from a self-reported questionnaire. The perceived exposure was assessed by a 6-item questionnaire. Two proximity-based exposures were constructed by division/brigade level and battalion/company level unit information using the Stellman exposure opportunity index model. The mean and median of serum TCDD levels was 1.2 parts per trillion (ppt) and 0.9 ppt, respectively. Only 2 Vietnam veterans had elevated levels of TCDD (>10 ppt). The levels of TCDD did not tend to increase with the likelihood of exposure to Agent Orange, as estimated from either proximity-based exposure or perceived self-reported exposure. The serum TCDD levels were not significantly different according to military unit, year of first deployment, duration of deployment, military rank, age, body mass index, and smoking status. The average serum TCDD levels in the Korean Vietnam veterans were lower than those reported for other occupationally or environmentally exposed groups and US Vietnam veterans, and their use as an objective marker of Agent Orange exposure may have some limitations. The unit of deployment, duration of deployment, year of first deployment, military rank, perceived self-reported exposure, and proximity-based exposure to Agent Orange were not associated with TCDD levels in Korean Vietnam veterans. Age, body mass index and smoking also were not associated with TCDD levels.

Objectives. We investigated associations among racial discrimination, psychological distress, and self-rated health among US-born and immigrant Black Americans. Methods. We conducted a cross-sectional analysis of a cohort of employed working-class Black Americans (193 US-born, 275 foreign-born). Results. Both US-born and foreign-born Black participants had high levels of exposure to poverty (51% and 57%, respectively) and racial discrimination (76% and 60%) and reported high levels of severe psychological distress (14% and 16% had a Kessler 6 [K6] score of 13 or greater); 17% and 7% reported fair or poor health. After controlling for relevant covariates, their risk parameters for racial discrimination (high vs no exposure) were 4.0 (95% confidence interval [CI] = 2.3, 5.6) and 3.3 (95% CI = 2.1, 4.5), respectively, for continuous K6 score; corresponding odds ratios for severe psychological distress were 6.9 (95% CI = 1.4, 35.7) and 6.8 (95% CI = 2.5, 18.3). No associations existed between racial discrimination and self-reported health, suggesting that an underlying propensity to report adversity does not account for our psychological distress findings. Conclusions. Our results attest to the salience of racial discrimination, nativity, and socioeconomic position in understanding the experiences and psychological health of Black Americans.

Background: Stereotypes in medicine have become exaggerated for the purpose of workplace amusement. Our objective was to assess the levels of “dark triad” personality traits expressed by individuals working in different health care specialties in comparison with the general population. Methods: We conducted a prospective, cross-sectional study within multiple departments of a UK secondary care teaching hospital. A total of 248 health care professionals participated, and 159 members of the general population were recruited as a comparison group. We measured 3 personality traits — narcissism, Machiavellianism and psychopathy — through the validated self-reported personality questionnaires Narcissistic Personality Inventory (NPI), MACH-IV and the Levenson Self-Report Psychopathy Scale (LSRP), respectively. Results: Health care professionals scored significantly lower on narcissism, Machiavellianism and psychopathy (mean scores 12.0, 53.0 and 44.7, respectively) than the general population (p < 0.001). Nursing professionals exhibited a significantly higher level of secondary psychopathy than medical professionals (p = 0.04, mean LSRP score 20.3). Within the cohort of medical professionals, surgeons expressed significantly higher levels of narcissism (p = 0.03, mean NPI score 15.0). Interpretation: Health care professionals expressed low levels of dark triad personality traits. The suggestion that health care professionals are avaricious and untrustworthy may be refuted, even for surgeons. PMID:26644545

Phosphocreatine, an Intracellular High-Energy Compound, is Found in the Extracellular Fluid of the Seminal Vesicles in Mice and Rats

High levels of phosphocreatine, a compound known to serve as an intracellular energy reserve, were found in the fluid contained in seminal vesicle glands. The concentrations of phosphocreatine in the extracellular fluid in the mouse and rat were found to be 5.6 ± 1.6 and 2.2 ± 0.8 μ mol/g, respectively, which are higher than the intracellular levels reported for smooth muscles. The creatine concentrations in the seminal vesicular fluid from these two species were 22.8 ± 3.1 and 13.0 ± 5.3 μ mol/g, respectively. These creatine levels are approximately 100 and 65 times higher than the creatine levels in mammalian blood. Smaller amounts of ATP (phosphocreatine/ATP ratio of 20-40) and traces of ADP were also found. Comparison of the pattern of distribution of macromolecules (proteins and DNA) with the distribution of phosphocreatine between the cells and the fluid of the seminal vesicle indicates that cell lysis did not account for the phosphocreatine in the seminal vesicle fluid. Rather, the available evidence strongly suggests that this high-energy compound is actively secreted. We found that in the testes, the sperm are exposed to the highest known creatine concentration in any mammalian tissue studied. Based on these results and other recent reports, we propose that the extracellular phosphocreatine, ATP, and creatine are involved in sperm metabolism.

Critically evaluated rotational-vibrational line positions and energy levels, with associated critically reviewed labels and uncertainties, are reported for two deuterated isotopologues of the H3(+) molecular ion: H2D(+) and D2H(+). The procedure MARVEL, standing for Measured Active Rotational-Vibrational Energy Levels, is used to determine the validated levels and lines and their self-consistent uncertainties based on the experimentally available information. The spectral ranges covered for the isotopologues H2D(+) and D2H(+) are 5.2-7105.5 and 23.0-6581.1 cm(-1), respectively. The MARVEL energy levels of the ortho and para forms of the ions are checked against ones determined from accurate variational nuclear motion computations employing the best available adiabatic ab initio potential energy surfaces of these isotopologues. The number of critically evaluated, validated and recommended experimental (levels, lines) are (109, 185) and (104, 136) for H2D(+) and D2H(+), respectively. The lists of assigned MARVEL lines and levels and variational levels obtained for H2D(+) and D2H(+) as part of this study are deposited in the ESI to this paper.

Two hydrophilic conjugated polymers, PmP-NOH and PmP36F-NOH, with polar diethanol-amine on the side chains and main chain structures of poly(meta-phenylene) and poly(meta-phenylene-alt-3,6-fluorene), respectively, are successfully synthesized. The films of PmP-NOH and PmP36F-NOH show absorption edges at 340 and 343 nm, respectively. The calculated optical bandgaps of the two polymers are 3.65 and 3.62 eV, respectively, the largest ones so far reported for hydrophilic conjugated polymers. PmP-NOH and PmP36F-NOH also possess deep-lying highest occupied molecular orbital levels of -6.19 and -6.15 eV, respectively. Inserting PmP-NOH and PmP36F-NOH as a cathode interlayer in inverted polymer solar cells with a PTB7/PC71 BM blend as the active layer, high power conversion efficiencies of 8.58% and 8.33%, respectively, are achieved, demonstrating that the two hydrophilic polymers are excellent interlayers for efficient inverted polymer solar cells. © 2015 WILEY-VCH Verlag GmbH & Co.

Physical activity (PA) is complex and a difficult behavior to assess as there is no ideal assessment tool(s) that can capture all contexts of PA. Therefore, it is important to understand how different assessment tools rank individuals. We examined the extent to which self-report and direct assessment PA tools yielded the same ranking of PA levels. PA levels were measured by the Modifiable Activity Questionnaire (MAQ) and pedometer at baseline among 855 white (W), African-American (AA), Japanese-American (JA), and Korean (K) men (mean age 45.3 years) in 3 geographic locations in the ERA JUMP study. Korean men were more active than W, AA, and JA men, according to both the MAQ and pedometer (MAQ total PA [mean ± SD]: 41.6 ± 17.8, 20.9 ± 9.9, 20.0 ± 9.1, and 29.4 ± 10.3 metabolic equivalent [MET] hours/week, respectively; pedometer: 9584.4 ± 449.4, 8363.8 ± 368.6, 8930.3 ± 285.6, 8335.7 ± 368.6 steps/day, respectively). Higher levels of total PA in Korean men, as shown by MAQ, were due to higher occupational PA. Spearman correlations between PA levels reported on the MAQ and pedometer indicated positive associations ranging from rho = 0.29 to 0.42 for total activity, rho = 0.13 to 0.35 for leisure activity, and rho = 0.10 to 0.26 for occupational activity. The 2 assessment methods correlated and were complementary rather than interchangeable. The MAQ revealed why Korean men were more active. In some subpopulations it may be necessary to assess PA domains other than leisure and to use more than 1 assessment tool to obtain a more representative picture of PA levels.

Although systems to collect information about suspected adverse drug reactions (ADRs) were established in many countries and by the WHO in the 1960s, few studies have examined reported ADRs related to national income. The aim of the study was to characterize ADRs reported to the WHO-ADR database, VigiBase™, and to relate data to national income. We analysed ADR reports submitted to VigiBase™ from 2000 to 2009 with respect to reporting rate, age and sex of patient, type, seriousness and medications. Reports were also analysed with respect to national income level, classified in accordance with the World Bank definition: low, lower-middle, upper-middle and high. We analysed 1,359,067 ADR reports including 3,013,074 ADRs. Overall, 16% of reports were serious and 60% were reported for females. High-income countries had the highest ADR reporting rates (range 3-613 reports/million inhabitants/year) and low-income countries the lowest (range 0-21). Distribution of ADRs across income groups with respect to age group, seriousness and sex was non-significant. Overall, the majority of ADRs were reported for nervous system medications, followed by cardiovascular medicines. Low-income countries reported relatively more ADRs for antiinfectives for systemic use than high-income countries, and high-income countries reported more ADRs for antineoplastic and immunomodulating agents than lower-income groups. This study showed that high-income countries had the highest ADR reporting rates and low-income countries the lowest, with large variations across countries in each group. Significant differences in ADR reporting rates were only found for ADRs of the type 'skin and subcutaneous tissue disorders' and for the therapeutic groups 'antiinfectives for systemic use' and 'antineoplastic and immunomodulation agents'. To strengthen ADR reporting rates, especially in low-income countries, more research is needed about the impact of organizational structures and economic resources of national pharmacovigilance centres and ADR reporting practices on the large variations in ADR reporting rates within income groups.

A 6-week-old girl, the first child of non-consanguineous parents, was admitted to the hospital for evaluation of vomiting. She was small for gestational age (1500 g). On admission, she weighed 1830 g, and appeared dehydrated. The blood glucose was 880 mg/dL. Insulin and C-peptide levels were <1 microIU/ml and 0.1 pmol/L, respectively. Antibodies of diabetes were negative. The serum triglyceride level was markedly elevated (5322 mg/dL). After a few days of insulin therapy, the triglyceride levels dramatically decreased, but cholestasis persisted. A liver biopsy revealed diffuse iron deposition and the diagnosis of neonatal hemochromatosis was established. In neonatal hemochromatosis, diabetes may occur as a result of iron deposition in the pancreas. The coexistence of neonatal diabetes secondary to neonatal hemochromatosis with a fatal course during the infancy period has not been previously reported. In this report, an infant with neonatal diabetes secondary to neonatal hemochromatosis is presented as the first case in the literature involving the coexistence of these two conditions.

Objective The purpose of this study was to examine the difference between self-reported hearing status and hearing impairment assessed using conventional audiometry. The associated factors were examined when a concordance between self-reported hearing and audiometric measures was lacking. Methods In total, 19,642 individuals ≥20 years of age who participated in the Korea National Health and Nutrition Examination Surveys conducted from 2009 through 2012 were enrolled. Pure-tone hearing threshold audiometry (PTA) was measured and classified into three levels: <25 dB (normal hearing); ≥25 dB <40 dB (mild hearing impairment); and ≥40 dB (moderate-to-severe hearing impairment). The self-reported hearing loss was categorized into 3 categories. The participants were categorized into three groups: the concordance (matched between self-reported hearing loss and audiometric PTA), overestimation (higher self-reported hearing loss compared to audiometric PTA), and underestimation groups (lower self-reported hearing loss compared to audiometric PTA). The associations of age, sex, education level, stress level, anxiety/depression, tympanic membrane (TM) status, hearing aid use, and tinnitus with the discrepancy between the hearing self-reported hearing loss and audiometric pure tone threshold results were analyzed using multinomial logistic regression analysis with complex sampling. Results Overall, 80.1%, 7.1%, and 12.8% of the participants were assigned to the concordance, overestimation, and underestimation groups, respectively. Older age (adjusted odds ratios [AORs] = 1.28 [95% confidence interval = 1.19–1.37] and 2.80 [2.62–2.99] for the overestimation and the underestimation groups, respectively), abnormal TM (2.17 [1.46–3.23] and 1.59 [1.17–2.15]), and tinnitus (2.44 [2.10–2.83] and 1.61 [1.38–1.87]) were positively correlated with both the overestimation and underestimation groups. Compared with specialized workers, service workers, manual workers, and the unemployed were more likely to be in the overestimation group (1.48 [1.11–1.98], 1.39 [1.04–1.86], and 1.50 [1.18–1.90], respectively), and service workers were more likely to be in the underestimation group (AOR = 1.42 [1.01–1.99]). Higher education level (0.77 [0.59–1.01] and 0.43 [0.33–0.57]) and hearing aid use (0.36 [0.17–0.77] and 0.23 [0.13–0.43]) were negatively associated with being in the underestimation group (0.43 [0.37–0.50]). Compared with males, females were less likely to be assigned to the underestimation group (0.43 [0.37–0.50]). Stress (1.98 [1.32–2.98]) and anxiety/depression (1.30 [1.06–1.59]) were associated with overestimation group. Conclusion Older age, lower education level, occupation, abnormal TM, non-hearing aid use, and tinnitus were related to both overestimation and underestimation groups. Male gender was related to underestimation, and stress and anxiety/depression were correlated with overestimation group. An understanding of these factors associated with the self-reported hearing loss will be instrumental to identifying and managing hearing-impaired individuals. PMID:28792529

If present in high enough concentrations, IL-1-Ra has the potential to inhibit Interleukin-1, the chief offender that promotes the pro-inflammatory cascade causing pain, swelling and joint dysfunction associated with osteoarthritis (OA). IL-1-Ra and growth factor levels were quantified from whole blood in this retrospective chart review investigation (n=20) using Zero and 15min incubation times respectively. The hypothesis that this process can significantly (p<0.0001) increase levels of IL-1-Ra was confirmed. Mean Arthrokinex™ induced IL-1-Ra levels reached a concentration of 13,288pg/mL and 12,809pg/mL compared to 518pg/mL at baseline, representing a 26-fold increase. Post conditioning levels of pro-inflammatories IL-1β, IL-6 and TNF α were not changed to any significant degree. The Arthrokinex™ blood conditioning process induces adequate levels of IL-1-Ra to alter the IL-1-Ra: IL-1β ratio and mitigate the inflammatory cascade, while increasing growth factors PDGF and TGF respectively.

A considerable proportion of all women undergoing IVFrespond poorly to gonadotropin stimulation. These women are reported to be associated with increased cancellation rates and lower pregnancy rates. It has been hypothesized that poor response to ovarian stimulation is a first sign of ovarian ageing or premature ovarian failure, which might be related to altered inflammatory response in the body. We aimed to compare follicular fluid presepsin levels between poor- and normo-responder patients to ovarian stimulation, to assess its relationship with reproductive outcomes. This study included infertility patients who underwent ovulation induction with either long GnRH agonist or GnRH antagonist protocols and who subsequently underwent IVF/ICSI. Included patients were assigned to two groups according to the Bologna criteria for poor ovarian response. Group 1 and 2 consisted of normo- and poor-responder patients, respectively.The 2 groups were compared in terms of FF presepsin levels. Also, any relationship between the FF presepsin levels and fertility outcomes was assessed within the groups. The groups were compared by using student’s t-test, Mann-Whitney U test and X2 test, where appropriate. Pregnancy rates were not significantly different between the groups (22.6% and 17.6%; P=0.650, respectively). FF presepsin levels were higher in Group 1, however, the difference was not statistically significant (298.0±797.4 and 149.2±422.3; P=0.190, respectively). FF presepsin levels did not significantly differ between pregnancy positive and the pregnancy negative patients in both Group 1 (243.6±531.1 and 314.3±866.5; P=0.055, respectively) and Group 2 (112.2±79.8 and 157.1±464.3; P=0.394, respectively). Consequently, FF presepsin seems not to be a reliable marker in predicting pregnancy in both normo-responder and poor-responder infertility groups. PMID:26309683

The need for accurate, automated protein classification methods continues to increase as advances in biotechnology uncover new proteins. G-protein coupled receptors (GPCRs) are a particularly difficult superfamily of proteins to classify due to extreme diversity among its members. Previous comparisons of BLAST, k-nearest neighbor (k-NN), hidden markov model (HMM) and support vector machine (SVM) using alignment-based features have suggested that classifiers at the complexity of SVM are needed to attain high accuracy. Here, analogous to document classification, we applied Decision Tree and Naive Bayes classifiers with chi-square feature selection on counts of n-grams (i.e. short peptide sequences of length n) to this classification task. Using the GPCR dataset and evaluation protocol from the previous study, the Naive Bayes classifier attained an accuracy of 93.0 and 92.4% in level I and level II subfamily classification respectively, while SVM has a reported accuracy of 88.4 and 86.3%. This is a 39.7 and 44.5% reduction in residual error for level I and level II subfamily classification, respectively. The Decision Tree, while inferior to SVM, outperforms HMM in both level I and level II subfamily classification. For those GPCR families whose profiles are stored in the Protein FAMilies database of alignments and HMMs (PFAM), our method performs comparably to a search against those profiles. Finally, our method can be generalized to other protein families by applying it to the superfamily of nuclear receptors with 94.5, 97.8 and 93.6% accuracy in family, level I and level II subfamily classification respectively.

Background: The study aimed to determine current status of knowledge, practices, and attitudes towards adverse drug reaction (ADR) reporting among private practitioners in Klang region of Malaysia. Methods: A total of 238 private practitioners in Klang valley were distributed a questionnaire consisting of seven questions, two knowledge-related, two practice-related and three attitude-related. Each favourable and unfavourable response was given a score of 1 and 0 respectively. Total score of 70% or more for each domain was considered “satisfactory” whereas less than 70% as “unsatisfactory”. Results: One hundred forty-five participants completed questionnaire. Knowledge assessment showed 83.4% responses stating that ADR reporting helps to identify safe drugs and 91.7% responded that it measures ADR incidence. Regarding practices, 76.6% respondents were willing to report only if confident that reaction is an ADR. Regarding attitudes, 81.9%, 66.9% and 23.5% participants showed complacency, ignorance, and indifference respectively. Unsatisfactory knowledge, practices, and attitudes were observed in 57.2%, 56.6%, and 73.1% respondents respectively. Satisfactory knowledge was significantly higher in respondent with higher qualification with odds ratio of 2.96 with 95% confidence interval of 1.48–5.93. Conclusion: The study showed unsatisfactory level of knowledge, practices, and attitudes towards ADR reporting among high proportion of private practitioners in Klang valley, Malaysia. PMID:23983578

This study reports levels and profiles of polycyclic aromatic hydrocarbons (PAHs) in dust samples collected from three different microenvironments (cars, air conditioner (AC) filters and household floor dust) of Jeddah, Saudi Arabia (KSA) and Kuwait. To the best of our knowledge, this is first study reporting PAHs in indoor microenvironments of KSA, which makes these findings important. Benzo(b)fluoranthene (BbF), benzo(a)pyrene (BaP), phenanthrene (Phe), and pyrene (Pyr) were found to be the major chemicals in dust samples from all selected microenvironments. ΣPAHs occurred at median concentrations (ng/g) of 3450, 2200, and 2650 in Saudi AC filter, car and household floor dust, respectively. The median levels (ng/g) of ΣPAHs in Kuwaiti car (950) and household floor (1675) dust samples were lower than Saudi dust. The PAHs profile in Saudi dust was dominated by high molecular weight (HMW) (4-5 ring) PAHs while in Kuwaiti dust 3 ring PAHs have marked contribution. BaP equivalent, a marker for carcinogenic PAHs, was high in Saudi household floor and AC filter dust with median levels (ng/g) of 370 and 455, respectively. Different exposure scenarios, using 5th percentile, median, mean, and 95th percentile levels, were estimated for adults and toddlers. For Saudi and Kuwaiti toddlers worst exposure scenario of ΣPAHs was calculated at 175 and 85ng/kg body weight/day (ng/kgbw/d), respectively. For Saudi toddlers, the calculated worst exposure scenarios for carcinogenic BaP (27.7) and BbF (29.3ng/kgbw/d) was 2-4 times higher than Kuwaiti toddlers. This study is based on small number of samples which necessitate more detailed studies for better understanding of dynamics of PAHs in the indoor environments of this region. Nevertheless, our finding supports the ongoing exposure of organic pollutants to population that accumulates indoor. Copyright © 2016. Published by Elsevier B.V.

Neuraxial anesthesia is increasingly recommended for hip/knee replacements as some studies show improved outcomes on the individual level. With hospital-level studies lacking, we assessed the relationship between hospital-level neuraxial anesthesia utilization and outcomes. National data on 808,237 total knee and 371,607 hip replacements were included (Premier Healthcare 2006 to 2014; 550 hospitals). Multivariable associations were measured between hospital-level neuraxial anesthesia volume (subgrouped into quartiles) and outcomes (respiratory/cardiac complications, blood transfusion/intensive care unit need, opioid utilization, and length/cost of hospitalization). Odds ratios (or percent change) and 95% CI are reported. Volume-outcome relationships were additionally assessed by plotting hospital-level neuraxial anesthesia volume against predicted hospital-specific outcomes; trend tests were applied with trendlines' R statistics reported. Annual hospital-specific neuraxial anesthesia volume varied greatly: interquartile range, 3 to 78 for hips and 6 to 163 for knees. Increasing frequency of neuraxial anesthesia was not associated with reliable improvements in any of the study's clinical outcomes. However, significant reductions of up to -14.1% (95% CI, -20.9% to -6.6%) and -15.6% (95% CI, -22.8% to -7.7%) were seen for hospitalization cost in knee and hip replacements, respectively, both in the third quartile of neuraxial volume. This coincided with significant volume effects for hospitalization cost; test for trend P < 0.001 for both procedures, R 0.13 and 0.41 for hip and knee replacements, respectively. Increased hospital-level use of neuraxial anesthesia is associated with lower hospitalization cost for lower joint replacements. However, additional studies are needed to elucidate all drivers of differences found before considering hospital-level neuraxial anesthesia use as a potential marker of quality.

Early treatment of phenylketonuria (ET-PKU) prevents mental retardation, but many patients still show cognitive and mood problems. In this study, it was investigated whether ET-PKU-patients have specific phenylalanine (Phe-)related problems with respect to social-cognitive functioning and social skills. Ninety five PKU-patients (mean age 21.6 ± 10.2 years) and 95 healthy controls (mean age 19.6 ± 8.7 years) were compared on performance of computerized and paper-and-pencil tasks measuring social-cognitive abilities and on parent- and self-reported social skills, using multivariate analyses of variance, and controlling for general cognitive ability (IQ-estimate). Further comparisons were made between patients using tetrahydrobiopterin (BH4, N = 30) and patients not using BH4. Associations with Phe-levels on the day of testing, during childhood, during adolescence and throughout life were examined. PKU-patients showed poorer social-cognitive functioning and reportedly had poorer social skills than controls (regardless of general cognitive abilities). Quality of social-cognitive functioning was negatively related to recent Phe-levels and Phe-levels between 8 and 12 years for adolescents with PKU. Quality of social skills was negatively related to lifetime phenylalanine levels in adult patients, and specifically to Phe-levels between 0 and 7, and between 8 and 12 years. There were no differences with respect to social outcome measures between the BH4 and non-BH4 groups. PKU-patients have Phe-related difficulties with social-cognitive functioning and social skills. Problems seem to be more evident among adolescents and adults with PKU. High Phe-levels during childhood and early adolescence seem to be of greater influence than current and recent Phe-levels for these patients.

The inter-relationships between objective (census based) and subjective (resident reported) measures of the residential environment is understudied in African American (AA) populations. Using data from the Life Influences on Fetal Environments Study (2009-2011; n = 1387) of AA women, we quantified the area-level variation in subjective reports of residential healthy food availability, walkability, safety, and disorder that can be accounted for with an objective neighborhood disadvantage index (NDI). Two-level generalized linear models estimated associations between objective and subjective measures of the residential environment, accounting for individual-level covariates. In unconditional models, intraclass correlation coefficients for block-group variance in subjective reports ranged from 11% (healthy food availability) to 30% (safety). Models accounting for the NDI (vs. both NDI and individual-level covariates) accounted for more variance in healthy food availability (23% vs. 8%) and social disorder (40% vs. 38%). The NDI and individual-level variables accounted for 39% and 51% of the area-level variation in walkability and safety, respectively. Associations between subjective and objective measures of the residential environment were significant and in the expected direction. Future studies on neighborhood effects on health, especially among AAs, should include a wide range of residential environment measures, including subjective, objective, and spatial contextual variables.

Tobacco use is disproportionately represented among both alcohol-use disorders (AUDs) and anxiety disorders (ANX) compared to the general population (Kalman et al., 2005). Despite this common overlap, little is known about how smokers with co-occurring AUD-ANX differ from their nonsmoking counterparts. Seventy-two patients participated in a larger clinical trial evaluating the efficacy of venlafaxine and cognitive-behavioral therapy for AUD-ANX. Differences between daily smokers (n = 23), chippers (n = 12) and nonsmokers (n = 37) with AUD-ANX were examined with respect to intensity and frequency of alcohol use, anxiety symptoms, depressed mood, and stress. Point prevalence of current daily smoking was 31.9%, which is considerably lower than traditionally reported in AUD studies. Consistent with predictions, daily smokers reported higher levels of alcohol dependence, average drinks per drinking occasion, and peak blood concentration levels in a day than nonsmokers during the 90 days prior to assessment. Chippers were nonsignificantly different from either smokers or nonsmokers. Smokers and nonsmokers did not differ with respect to percent heavy drinking days or emotional symptoms. PMID:18656314

Effect of MMF stub on the sensitivity of a photonic crystal fiber interferometer sensor at 1550 nm

Dhara, P.; Singh, Vinod K.

2015-01-01

A simple photonic crystal fiber (PCF) based Mach-Zehnder interferometric sensor is reported for sensing the refractive index and level of liquid. The sensing head is formed by all-fiber in-line single mode-multi mode-photonic crystal-single mode fiber structure using the fusion splicing method. The interferometric pattern, observed in the PCF interferometer using monochromatic source and temperature sensing arrangement, is novel and reported for the first time to the best of our knowledge. The refractive index sensitivity of the interferometric device is increased by using multimode fiber. The output intensity at the end of lead-out single mode fiber decreases with increase in refractive index of surrounding. The index sensitivities of the interferometric devices are 440.32 μw/RIU, 267.48 μw/RIU and 195.36 μw/RIU with sensing length 2.10 cm, 5.50 cm and 7.20 cm respectively. A 7.20 cm longed PCF sensor exhibits liquid level sensitivities -1.032 μw/cm, -1.197 μw/cm, and -1.489 μw/cm for three different liquid respectively.

The purpose of this investigation was to report on the total phenolics, anthocyanins, and oxygen radical absorbance capacity (ORAC) of strawberry, peach, and apple, the influence of dehydration and ascorbic acid treatments on the levels of these compounds, and the effect of these treatments on fruit color. Results showed that fresh strawberry had the highest levels for total phenolics [5317.9 mg of chlorogenic acid equivalents (CAE)/kg], whereas lower levels were found in fresh apple and peach (3392.1 and 1973.1 mg of CAE/kg, respectively), and for anthocyanins (138.8 mg/kg), whereas lower levels were found in fresh apple and peaches (11.0 and 18.9 mg/kg, respectively; fresh strawberry had an ORAC value of 62.9 mM/kg Trolox equivalents. The fresh apple and peach were found to have ORAC values of 14.7 and 11.4 mM/kg of Trolox equivalents, respectively. The color values indicated that the addition of 0.1% ascorbic acid increased the lightness (L) and decreased the redness (a) and yellowness (b) color values of fresh strawberry, peach, and apple, sliced samples, and the puree made from them. Also, results showed that dehydration is a good method to keep the concentrations of total phenolics and anthocyanins and ORAC values at high levels.

Reporting and interpreting research in PSPB: practices, principles, and pragmatics.

Kashy, Deborah A; Donnellan, M Brent; Ackerman, Robert A; Russell, Daniel W

2009-09-01

This article is designed to provide psychologists who publish articles in Personality and Social Psychology Bulletin (PSPB) with a set of basic issues to consider when reporting their analyses and results. We first assessed the current reporting practices of social and personality psychologists by conducting an analysis of PSPB articles published in the first half of 2007. We evaluated the completeness of these reports with respect to the level of detail in both the Method and Results sections. We then used this information to develop recommendations that we hope will enhance the reporting of quantitative research in social and personality psychology. These suggestions emphasize ways to increase transparency in research reports. Transparency facilitates replication and a critical evaluation of research, thereby promoting scientific progress.

2017-03-01

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.

Problem behaviours in dogs rehomed through animal shelters can jeopardise the long-term success of adoptions. In this study, data from 61 adolescent and adult dog adoptions that occurred through an animal shelter in Auckland, New Zealand, from 1 November 2015 to 31 July 2016 were analysed to describe the frequency of problem behaviours and level of adopter concern at different time points post-adoption. Amongst the 57 dogs with behavioural information available, 40 (70%) had at least one reported problem behaviour, and the most frequently reported problem behaviours were poor manners (46%), destruction of household items (30%), and excessively high energy (28%). Very few dogs showed territorial aggression when objects or food items were removed (2% and 4%, respectively). However, aggression toward people or other dogs was frequently reported (19% and 19%, respectively). Of the 54 adopters that provided a response about their level of concern over their dog’s problem behaviours, 24 (44%) were not concerned at all, 23 (43%) were a little concerned, 4 (7%) were moderately concerned, and 3 (6%) were very concerned. Based on our interpretation of these findings, post-adoption support programmes targeted toward teaching adopters how to correctly train their dogs may be beneficial to increasing adoption satisfaction.

This article examined differences in condom use during anal intercourse among men who have sex with men (MSM) and male-to-female transgender women in Jakarta, Indonesia. A cross-sectional design, structured interviews, and hierarchical linear modeling were used to examine condom use among MSM recruited from entertainment places (EPs; e.g., discotheques/dance clubs/karaoke bars), massage parlors (MPs), and among transgender women who congregated and/or sought sexual partners on streets/parks (S/P). The sample consisted of 91, 97, and 114 of MSM-EP, MSM-MP, and transgender-S/P, respectively. Respondents reported on 641 unique sexual partner encounters, which were "nested" within 302 respondents. Reported condom use was high, 66%, 84%, and 83% for MSM-EP, MSM-MP, and transgender-S/P, respectively, and varied across type of respondent. At the individual level, depressive symptoms and history of physical abuse during childhood and adulthood were associated with lower condom use (p < .05). By contrast, having a higher level of education was associated with more condom use (p < .05). At the partner level, condom use was associated with type of partners and the use of club drugs before sex. HIV-prevention efforts should take into account the multilevel determinants of condom use within these populations. © The Author(s) 2013.

2016-05-01

Reporter proteins are essential tools in the study of biological processes and are employed to monitor changes in gene expression and protein levels. Luciferases are reporter proteins that enable rapid and highly sensitive detection with an outstanding dynamic range. Here we evaluated the usefulness of the 19 kDa luciferase NanoLuc (Nluc), derived from the deep sea shrimp Oplophorus gracilirostris, as a reporter protein in yeast. Cassettes with codon-optimized genes expressing yeast Nluc (yNluc) or its destabilized derivative yNlucPEST have been assembled in the context of the dominant drug resistance marker kanMX. The reporter proteins do not impair the growth of yeast cells and exhibit half-lives of 40 and 5 min, respectively. The commercial substrate Nano-Glo® is compatible with detection of yNluc bioluminescence in < 50 cells. Using the unstable yNlucPEST to report on the rapid and transient expression of a heat-shock promoter (PCYC1-HSE ), we found a close match between the intensity of the bioluminescent signal and mRNA levels during both induction and decay. We demonstrated that the bioluminescence of yNluc fused to the C-terminus of a temperature-sensitive protein reports on its protein levels. In conclusion, yNluc and yNlucPEST are valuable new reporter proteins suitable for experiments with yeast using standard commercial substrate. © 2016 The Authors.

U.S. Hispanics disproportionately show health burdens that may be decreased by discussing physical activity (PA) and healthy eating with their healthcare providers (HCPs). We examined the perceptions of both HCPs and low-income Hispanic patients regarding the dynamics of these communications. We surveyed 295 low-income Hispanic patients and interviewed 14 HCPs at three community health clinics. Patients were asked about their comfort level with HCPs, how often their HCP discussed PA and healthy eating, and the likelihood of following advice on PA and healthy eating. HCPs were asked about their delivery (frequency/duration) and perceived effectiveness in providing such advice. Patients reported feeling "most comfortable" with their physicians (57%) with a lower proportion (19%) feeling "most comfortable" with nurses. Nearly all patients (95%) reported being very likely to follow the advice of their physician. On average, HCPs (physicians and nurses) reported discussing PA and healthy eating with 85% and 80% of their patients, respectively. In contrast, a fewer proportion of patients (65.8%) reported that their physician discussed PA and healthy eating "some" or "a lot" of the time. Overall, physicians reported discussing PA and healthy eating for an average of 5 and 6 min, respectively; whereas nurses reported discussing PA and healthy eating for an average of 12 and 19 min, respectively. Further study on the content and delivery of conversations between HCPs and their low-income Hispanic patients regarding PA and healthy eating could be vital to optimally impact health behaviors.

The US Geological Survey and the Idaho Department of Water Resources, in response to a request from the US Department of Energy, sampled 18 sites as part of a long-term project to monitor water quality of the Snake River Plain aquifer from the southern boundary of the Idaho National Engineering Laboratory to the Hagerman area. Water samples were collected and analyzed for manmade pollutants and naturally occurring constituents. The samples were collected from six irrigation wells, seven domestic wells, two springs, one stock well, one dairy well, and one observation well. Quality assurance samples also were collected and analyzed. Themore » water samples were analyzed for selected radionuclides, inorganic constituents, organic compounds, and bacteria. None of the samples analyzed for radionuclides, inorganic constituents, or organic compounds exceeded the established maximum contaminant levels for drinking water. Most of the radionuclide and inorganic constituent concentrations exceeded their respective reporting levels. All the samples analyzed for dissolved organic carbon had concentrations that exceeded their reporting level. Concentrations of 1,1,1 -trichloroethane exceeded the reporting level in two water samples. Two samples and a quality assurance replicate contained reportable concentrations of 2, 4-D. One sample contained fecal coliform bacteria counts that exceeded established maximum contaminant levels for drinking water.« less

Some considerations about Gaussian basis sets for electric property calculations

Arruda, Priscilla M.; Canal Neto, A.; Jorge, F. E.

Recently, segmented contracted basis sets of double, triple, and quadruple zeta valence quality plus polarization functions (XZP, X = D, T, and Q, respectively) for the atoms from H to Ar were reported. In this work, with the objective of having a better description of polarizabilities, the QZP set was augmented with diffuse (s and p symmetries) and polarization (p, d, f, and g symmetries) functions that were chosen to maximize the mean dipole polarizability at the UHF and UMP2 levels, respectively. At the HF and B3LYP levels of theory, electric dipole moment and static polarizability for a sample of molecules were evaluated. Comparison with experimental data and results obtained with a similar size basis set, whose diffuse functions were optimized for the ground state energy of the anion, was done.

Purpose Three-fourths of patients with advanced cancer are reported to suffer from pain. A primary barrier to provision of adequate symptom treatment is failure to appreciate the intensity of the symptoms patients are experiencing. Because data on Bangladeshi and Nepalese patients’ perceptions of their symptomatic status are limited, we sought such information using a cell phone questionnaire. Methods At tertiary care centers in Dhaka and Kathmandu, we recruited 640 and 383 adult patients, respectively, with incurable malignancy presenting for outpatient visits and instructed them for that single visit on one-time completion of a cell phone platform 15-item survey of questions about common cancer-associated symptoms and their magnitudes using Likert scales of 0 to 10. The questions were taken from the Edmonton Symptom Assessment System and the Brief Pain Inventory instruments. Results All but two Bangladeshi patients recruited agreed to study participation. Two-thirds of Bangladeshi patients reported usual pain levels ≥ 5, and 50% of Nepalese patients reported usual pain levels ≥ 4 (population differences significant at P < .001). Conclusion Bangladeshi and Nepalese adults with advanced cancer are comfortable with cell phone questionnaires about their symptoms and report high levels of pain. Greater attention to the suffering of these patients is warranted. PMID:28717768

A prospective cohort study was conducted to analyze whether self-reported fatigue predicts overall survival in patients with esophageal cancer. Patients enrolled in the Mayo Clinic Esophageal Adenocarcinoma and Barrett's Esophagus Registry between September 2001 and January 2009 who completed a baseline quality of life instrument were eligible for evaluation. The fatigue component was scored on a 0-10 scale, with 0 as extreme fatigue. Patients were categorized as having a decreased energy level if they reported a score of ≤ 5. Fatigue scores ≥ 6 reflect normal levels of energy. Data from a total of 659 enrolled patients were analyzed. A total of 392 (59 %) and 267 (41 %) patients reported decreased and normal energy, respectively. Univariate analysis indicates patients with normal energy had improved 5-year survival compared to patients with decreased energy (37 vs 28 %, hazard ratio (HR) 0.74, p = 0.006). Among the patients with locally advanced disease, the same relationship was seen (28 vs 17 %, HR = 0.67, p = 0.003); this remained significant on multivariate analysis (HR = 0.71, p = 0.015). A decreased energy level is associated with poor survival in patients with esophageal cancer. Thus, patients with high levels of fatigue should be referred for psychological support and be considered for therapy aimed at amelioration of fatigue symptoms.

Accuracy assessment is a standard protocol of National Land Cover Database (NLCD) mapping. Here we report agreement statistics between map and reference labels for NLCD 2011, which includes land cover for ca. 2001, ca. 2006, and ca. 2011. The two main objectives were assessment of agreement between map and reference labels for the three, single-date NLCD land cover products at Level II and Level I of the classification hierarchy, and agreement for 17 land cover change reporting themes based on Level I classes (e.g., forest loss; forest gain; forest, no change) for three change periods (2001–2006, 2006–2011, and 2001–2011). The single-date overall accuracies were 82%, 83%, and 83% at Level II and 88%, 89%, and 89% at Level I for 2011, 2006, and 2001, respectively. Many class-specific user's accuracies met or exceeded a previously established nominal accuracy benchmark of 85%. Overall accuracies for 2006 and 2001 land cover components of NLCD 2011 were approximately 4% higher (at Level II and Level I) than the overall accuracies for the same components of NLCD 2006. The high Level I overall, user's, and producer's accuracies for the single-date eras in NLCD 2011 did not translate into high class-specific user's and producer's accuracies for many of the 17 change reporting themes. User's accuracies were high for the no change reporting themes, commonly exceeding 85%, but were typically much lower for the reporting themes that represented change. Only forest loss, forest gain, and urban gain had user's accuracies that exceeded 70%. Lower user's accuracies for the other change reporting themes may be attributable to the difficulty in determining the context of grass (e.g., open urban, grassland, agriculture) and between the components of the forest-shrubland-grassland gradient at either the mapping phase, reference label assignment phase, or both. NLCD 2011 user's accuracies for forest loss, forest gain, and urban gain compare favorably with results from other land cover change accuracy assessments.

This paper is the fourth of a series of papers reporting critically evaluated rotational-vibrational line positions, transition intensities, pressure dependences, and energy levels, with associated critically reviewed assignments and uncertainties, for all the main isotopologues of water. This paper presents energy level and transition data for the following doubly and triply substituted isotopologues of water: D216O, D217O, and D218O. The MARVEL (Measured Active Rotational-Vibrational Energy Levels) procedure is used to determine the levels, the lines, and their self-consistent uncertainties for the spectral regions 0-14 016, 0-7969, and 0-9108 cm-1 for D216O, D217O, and D218O, respectively. For D216O, D217O, and D218O, 53 534, 600, and 12 167 lines are considered, respectively, from spectra recorded in absorption at room temperature and in emission at elevated temperatures. The number of validated energy levels is 12 269, 338, and 3351 for D216O, D217O, and D218O, respectively. The energy levels have been checked against the ones determined, with an average accuracy of about 0.03 cm-1, from variational rovibrational computations employing exact kinetic energy operators and an accurate potential energy surface. Furthermore, the rovibrational labels of the energy levels have been validated by an analysis of the computed wavefunctions using the rigid-rotor decomposition (RRD) scheme. The extensive list of MARVEL lines and levels obtained is deposited in the Supplementary Material of this paper, in a distributed information system applied to water, W@DIS, and on the official MARVEL website, where they can easily be retrieved.

To explore possible interrelationships among resistance to peer pressure, risky decision-making and health risk behaviors among young adolescents. Based on the cluster sampling method, the participants who were recruited from 5 junior middle schools in Guangzhou and 3 junior middle schools in Shenyang city on October, 2010, were administered to complete the questionnaire concerned with their experiences with drinking and smoking during the past 30 days preceding the survey, and the hours using computer daily both in weekdays and in weekend. The level of resistance to peer influence and risky decision-making were assessed by Resistance to peer influence scale (RPIS) and Youth decision-making questionnaire (YDMQ). Logistic regression was used to explore possible interrelationships among resistance to peer influence, risky decision-making and health risk behaviors among young adolescents. A total of 1985 questionnaires were valid, including 1001(50.4%) boys and 984 (49.6%) girls. About 27.1% (537/1985) junior middle school students reported having health risk behaviors, boys' (30.7%, 307/1001) was higher than girls' (23.4%, 230/984) with significant gender difference (P < 0.05). The prevalence of smoking, drinking during the past 30 days before the survey and using computer over 3 hours daily in weekdays and in weekend were 5.1% (102/1985), 14.3% (284/1985), 3.5% (70/1985) and 13.7% (272/1985), respectively. The rate of drinking, using computer over 3 hours daily in weekdays and in weekend were higher in males (16.4% (164/1001), 4.5% (45/1001), 16.2% (162/1001)) than those in females (12.2% (120/984), 2.5% (25/984), 11.2% (110/984)) (P < 0.05). The scores of RPIS and YDMQ of the two cities adolescents were 2.82 ± 0.39 and 1.68 ± 0.62. The students reported smoking, drinking during the past 30 days before the survey and using computer over 3 hours daily in weekend gained lower RPIS scores (2.43 ± 0.40, 2.61 ± 0.41, 2.77 ± 0.40) than their counterparts who didn't report these kind of health risk behaviors (2.84 ± 0.38, 2.85 ± 0.38, 2.82 ± 0.39)(P < 0.05). And those reported smoking, drinking during the past 30 days before the survey and using computer over 3 hours daily in weekdays and in weekend gained higher YDMQ scores (2.38 ± 0.66, 2.06 ± 0.66, 1.97 ± 0.72, 1.84 ± 0.64, respectively) than their counterparts who didn't report these kind of health risk behaviors (1.64 ± 0.38, 1.61 ± 0.58, 1.67 ± 0.61, 1.65 ± 0.61, respectively) (P < 0.05). After adjusting gender, area, parental education degree, self-reported family economic condition, multi-variant logistic regression analysis indicated that the low and middle level of resistance to peer influence (low and middle level vs high level, had odds ratios of 2.97 (1.96 - 4.50) and 1.51 (1.05 - 2.16)), and also the middle and high level of risky decision-making (middle and high level vs low level, had odds ratios of 1.62 (1.19 - 2.22) and 3.43 (2.39 - 4.90)) were all the risk factors of adolescent health risk behaviors. Adolescents with poor ability of resistance to peer pressure and high risky decision-making were both the risk factors of adolescent health risk behaviors.

Food consumption data from national dietary surveys were combined with brand-specific-use levels reported by beverage manufacturers to calculate the exposure to benzoic acid and its salts (INS Nos 210-213) from non-alcoholic beverages in Brazil, Canada, Mexico and the United States. These four jurisdictions were identified as having some of the most prevalent use of benzoates in beverages globally. Use levels were weighted according to the brand's market volume share in the respective countries. Benzoates were reported to be used primarily in 'water-based flavoured drinks' (Codex General Standard for Food Additives (GSFA) category 14.1.4). As such, the assessments focused only on intakes from these beverage types. Two different models were established to determine exposure: probabilistic (representing non-brand loyal consumers) and distributional (representing brand-loyal consumers). All reported-use levels were incorporated into both models, including those above the Codex interim maximum benzoate use level (250 mg kg -1 ). The exception to this was in the brand-loyal models for consumers of regular carbonated soft drinks (brand loyal category) which used (1) the interim maximum use level for beverages with a pH ≤ 3.5 and (2) all reported use levels for beverages pH > 3.5 (up to 438 mg kg -1 ). The estimated exposure levels using both models were significantly lower than the ADI established for benzoates at the mean level of intake (4-40% ADI) and lower than - or at the ADI only for toddlers/children - at the 95th percentile (23-110% ADI). The results rendered in the models do not indicate a safety concern in these jurisdictions, and as such provide support for maintaining the current Codex interim maximum benzoate level of 250 mg kg -1 in water-based beverages.

Cut-off levels for breath carbon monoxide as a marker for cigarette smoking.

PubMed

Javors, Martin A; Hatch, John P; Lamb, Richard J

2005-02-01

Current clinical studies often use a breath carbon monoxide (BCO) cut-off level of 8 parts per million (p.p.m.) or higher to identify smoking. In this study, the cut-off level of BCO as an indicator of smoking over the past 24 hours was re-examined. BCO and self-reported smoking were obtained each weekday for up to 14 weeks in 213 subjects paid to deliver reduced BCO values. Analysis of 12 386 paired values for reported smoking and BCO were analyzed. The 25% quartile, median and 75% quartile values for BCO were 1, 1 and 2 p.p.m. on non-smoking days and 2, 5 and 12 p.p.m. on smoking days, respectively. Receiver-operating characteristic (ROC) analysis indicated that BCO provided high diagnostic accuracy to distinguish between smoking and non-smoking days [area under the curve (AUC) = 0.853, P < 0.0001]. The highest combined sensitivity and specificity was observed at a BCO cut-off level of 3 p.p.m. (sensitivity = 71.5%; specificity = 84.8%). At a BCO cut-off of 8 p.p.m. sensitivity and specificity were 40.6% and 98.2%, respectively, indicating that many smokers would be falsely classified as abstinent. Finally, the percentage of true tests (positive and negative) was highest at a BCO cut-off of 2 p.p.m. (80.2%). BCO cut-off levels well below 8 p.p.m and as low as 2-3 p.p.m. may be more useful when it is important to maximize identification of smoking abstinence with a high degree of certainty.

Intravenous sedation as an adjunct to advanced comprehensive dental implantology: the patient's perspective and operator satisfaction.

PubMed

McCrea, S J J

2015-03-13

The aim of this three-year study was to evaluate whether elective comprehensive dental implant procedures involving guided bone and soft tissue regeneration carried out under intravenous sedation (midazolam) would be influenced by patient self-reported pre-operative anxiety levels; age and gender; effect the level of sedation with respect to the amount of sedative administered and the time taken in the procedures; effect patient intra-operative cooperation, and post-operative levels of patient satisfaction; influence further acceptance of dental implant surgical procedures; effect intra-operative surgeon satisfaction and consequently his/her post-operative sense of achievement.Design Single centre general dental practice, open study as a clinical audit. One hundred and seventy-three consecutive patients undergoing prolonged surgical procedures involving dental implantology with the adjunctive facility of intravenous sedation were monitored with respect to self-reported levels of anxiety. Vital signs of heart rate, mean systolic and diastolic blood pressure and arterial oxygen saturation were recorded and monitored pre-intra- and post-surgery. A post-operative questionnaire was completed as to the perceptions of the level of sedation. A distinct relationship between self-reported pre-operative anxiety levels, age and gender were recorded - the younger the age, the higher the anxiety, with females dominating. Females required more midazolam than males. However, the analysis of the data as a whole, incorporating both genders, revealed a non-significant correlation result. The correlation between the midazolam dosage and the Corah anxiety score produced a p value result of: r (161) = 0.008, p <0.01. Forty-four percent of the patients described themselves as having 'high anxiety and fear of the dentist', however, 99.4% of the patients answered 'yes' to having sedation again in the future. For the purpose of this study, detailed consideration was given to the gender specific results in order to reveal a wider understanding of who poses as a 'cooperative patient'. The results should prompt a rethink as to who a cooperative patient is, and whether the self-assessed level of anxiety will influence further acceptance of dental implant surgical procedures under intravenous sedation.

To provide a comprehensive review of clinical outcomes and retear rates after patch use in rotator cuff repair, and to determine the differences between available graft types and techniques. A systematic review was conducted from database (PubMed, Medline, Scopus, Embase) inception to January 2015 for English-language articles reporting outcome data with 9 months' minimum follow-up. Studies were assessed by 2 reviewers who collected pertinent data, with outcomes combined to generate frequency-weighted means. Twenty-four studies met the inclusion criteria. The frequency-weighted mean age was 61.9 years with 35.4 months' follow-up. The mean improvements in postoperative range of motion in the forward elevation, abduction, external rotation, and internal rotation planes were 58.6°, 66.2°, 16.6°, and 16.1°, respectively, and postoperative abduction strength improved by 3.84 kg. American Shoulder and Elbow Surgeons, University of California-Los Angeles, Constant, Penn, and Oxford scores improved by 39.3, 10.7, 40.8, 34.4, and 17.6, respectively. Augmentation and interposition techniques showed similar improvements in range of motion, strength, and patient-reported outcomes (PROs), whereas xenografts showed less improvement in PROs compared with other graft types. Studies reported improvements in pain and activities of daily living (ADLs), with greater than 90% overall satisfaction, although few patients (13%) were able to return to preinjury activity. Whereas interposition and augmentation techniques showed similar improvements in pain and ADLs, xenografts showed less improvement in ADLs than other graft types. The overall retear rate was 25%, with rates of 34% and 12% for augmentation and interposition, respectively, and rates of 44%, 23%, and 15% for xenografts, allografts, and synthetic grafts, respectively. We report improvements in clinical and functional outcomes, with similar results for augmentation and interposition techniques, whereas xenografts showed less improvement than synthetic grafts and allografts in PROs and ADLs. Retear rates may be lower with the interposition technique or in patients with synthetic grafts or allografts. Level IV, systematic review of Level II through IV studies.

OBJECTIVE Among chronic dialysis patients an obesity paradox or reverse epidemiology is known, but it is no clear whether the association of body size and muscle mass with survival is consistent across race, especially in East Asian versus Caucasian and African–American hemodialysis (HD) patients PATIENTS AND METHODS Using 20,818 HD patients in South Korea from February 1, 2001 to June 30, 2009 and 20,000 matched HD patients in the United States (10,000 Caucasians and 10,000 African–Americans) from July 1, 2001 to June 30, 2006, we compared mortality associations of baseline body mass index (BMI) and serum creatinine (Cr) level, as likely surrogates of obesity and muscle mass across the three races. RESULTS In Korean HD patients higher BMI together with higher serum Cr levels were associated with greater survival, as previously reported from US and European studies. In the matched cohort (n=10,000 in each of the three races), mortality risks were lower across higher BMI and serum Cr levels, and these association were similar in all three races (reference groups: patients with BMI >25.0 kg/m2 or serum Cr >12 mg/dL in each race). Patients with BMI level ≤18.5 kg/m2 (underweight) reported 78%, 79% and 57% higher mortality risk among Caucasian, African–American and Korean, respectively, and so did patients with serum Cr level ≤6.0 mg/dL, who reported 108%, 87% and 78% higher mortality, respectively. CONCLUSION Race does not modify the association of higher body size and muscle mass with greater survival in HD patients. Given consistency of the obesity paradox, which may be related to mitigated effect of protein–energy wasting on mortality irrespective of racial disparities, nutritional support to improve survival should be tested across all races of HD patients.

Unreported minor crashes have importance as a surrogate for more serious crashes that require infrastructure, education, and enforcement strategies; and they still inflict damages. To study factors that influence underreporting, cause, and severity of minor crashes; a survey was performed in Kunming and Beijing to collect self-reported personal characteristics and crash history data of the three major urban road users in China: automobile drivers, bicycle riders and electric bike (e-bike) riders. Underreporting rates of automobile to automobile, automobile to non-motorized vehicle, and non-motorized vehicle to non-motorized vehicle crashes are 56%, 77% and 94%, respectively. Minor crashes with higher reported injury severity levels are more likely to be reported. E-bike riders without a driver's license are more likely to cause crashes. Licensing and education could be an effective way to reduce their crashes. The party that is not at fault in a crash is more likely to sustain high level of injury.

Gender differences in economic support and well-being of older Asians.

Ofstedal, Mary Beth; Reidy, Erin; Knodel, John

2004-09-01

This report provides a comprehensive analysis of gender differences in economic support and well-being in eight countries in Southern and Eastern Asia (Bangladesh, Malaysia, Indonesia, Singapore, Thailand, Vietnam, Philippines, and Taiwan). We examine multiple economic indicators, including sources of income, receipt of financial and material support, income levels, ownership of assets, and subjective well-being. Results show substantial variation in gender differences across indicators and provide an important qualification to widely held views concerning the globally disadvantaged position of older women. Whereas men tend to report higher levels of income than women, there is generally little gender difference in housing characteristics, asset ownership, or reports of subjective economic well-being. Unmarried women are economically advantaged compared to unmarried men in some respects, in part because they are more likely to be embedded in multigenerational households and receive both direct and indirect forms of support from family members.

Kushner, Shauna C; Tackett, Jennifer L

2017-03-01

In this article, we investigated the extent and nature of informant discrepancies on parent- and adolescent self-report versions of a checklist measuring youth exposure to life stressors. Specifically, we examined (a) mean-level differences, relative consistency, and consensus for family-level and youth-specific stressors and (b) the utility of parent-youth discrepancies in accounting for variance in youth temperament and psychopathology. Participants were 106 parent-child dyads (47 male, 59 female; 90.6% mothers) aged 13 to 18 years old ( M = 16.01, SD = 1.29). The results revealed evidence for both congruence and divergence in parent and youth reports, particularly with respect to respondents' accounts of youth-specific stressors. Discrepancies for youth-specific stressors were associated with adolescents' negative affectivity, surgency, effortful control, and internalizing problems. Discrepancies for youth stressors may therefore reveal individual differences in emotionality and self-regulation, thus reflecting meaningful variance in adolescents' functioning.

College students (N = 3,435) in 26 cultures reported their perceptions of age-related changes in physical, cognitive, and socioemotional areas of functioning and rated societal views of aging within their culture. There was widespread cross-cultural consensus regarding the expected direction of aging trajectories with (1) perceived declines in societal views of aging, physical attractiveness, the ability to perform everyday tasks, and new learning, (2) perceived increases in wisdom, knowledge, and received respect, and (3) perceived stability in family authority and life satisfaction. Cross-cultural variations in aging perceptions were associated with culture-level indicators of population aging, education levels, values, and national character stereotypes. These associations were stronger for societal views on aging and perceptions of socioemotional changes than for perceptions of physical and cognitive changes. A consideration of culture-level variables also suggested that previously reported differences in aging perceptions between Asian and Western countries may be related to differences in population structure.

By using Shanghai and Shenzhen A-share listed companies in heavy polluting industry as research object from 2009 to 2014, this paper examines the relationship between media reporting, carbon information disclosure, and the cost of equity financing. The results show that media reporting can improve the quality of carbon information disclosure, and carbon information disclosure level is negatively associated with the cost of equity financing. This study also finds that financial carbon information disclosure and non-financial carbon information disclosure have significant negative relationship with the cost of equity financing respectively. Moreover, this paper shows that media reporting can strengthen the relationship between carbon information disclosure and the cost of equity financing.

Benefits of physical activity in the prevention and management of stroke are well documented in the literature. There is increasing evidence that stroke survivors in South-West Nigeria are physically inactive. Data on barriers to the achievement of the recommended physical activity levels including its differences along socio-demographic characteristics among stroke survivors in South-West Nigeria are needed. The Exercise Benefits and Barrier Scale and the International Physical Activity Questionnaire were administered on 121 stroke survivors to determine their perceived barriers to physical activity and physical activity levels respectively. Information on socio-demographic data and clinical variables were also collected. The sample included 70.2% males, with majority of the participants reporting low physical activity levels (80.2%) and high perceived barriers (Mean = 48.13, SD = 7.88). The four most reported common barriers among stroke survivors were access to exercise facilities (95.0%), being embarrassed to exercise (94.2%), economic cost demands of exercise (94.2%) and notion that people in exercise clothes look funny (94.2%) respectively. There were no significant differences found in barriers to physical activity between gender (U = 1471.00, P = 0.74) and across each of: occupational status (H = 4.37, P = 0.22), age group (H = 0.82, P = 0.84) and educational levels (H = 4.56, P = 0.33). Significant difference however existed in perceived barriers across marital status categories (H = 12.87, P = 0.05). Stroke survivors indicated high perceived barriers to physical activity and these barriers were associated with marital status.

Image analysis methods for assessing levels of image plane nonuniformity and stochastic noise in a magnetic resonance image of a homogeneous phantom.

PubMed

Magnusson, P; Olsson, L E

2000-08-01

Magnetic response image plane nonuniformity and stochastic noise are properties that greatly influence the outcome of quantitative magnetic resonance imaging (MRI) evaluations such as gel dosimetry measurements using MRI. To study these properties, robust and accurate image analysis methods are required. New nonuniformity level assessment methods were designed, since previous methods were found to be insufficiently robust and accurate. The new and previously reported nonuniformity level assessment methods were analyzed with respect to, for example, insensitivity to stochastic noise; and previously reported stochastic noise level assessment methods with respect to insensitivity to nonuniformity. Using the same image data, different methods were found to assess significantly different levels of nonuniformity. Nonuniformity levels obtained using methods that count pixels in an intensity interval, and obtained using methods that use only intensity values, were found not to be comparable. The latter were found preferable, since they assess the quantity intrinsically sought. A new method which calculates a deviation image, with every pixel representing the deviation from a reference intensity, was least sensitive to stochastic noise. Furthermore, unlike any other analyzed method, it includes all intensity variations across the phantom area and allows for studies of nonuniformity shapes. This new method was designed for accurate studies of nonuniformities in gel dosimetry measurements, but could also be used with benefit in quality assurance and acceptance testing of MRI, scintillation camera, and computer tomography systems. The stochastic noise level was found to be greatly method dependent. Two methods were found to be insensitive to nonuniformity and also simple to use in practice. One method assesses the stochastic noise level as the average of the levels at five different positions within the phantom area, and the other assesses the stochastic noise in a region outside the phantom area.

Serum cotinine levels are a reliable marker of tobacco use. Few studies have validated questionnaires assessing smoking and exposure to environmental tobacco smoke (ETS) against serum levels. We undertook such a study in industrial workers in India. We chose 426 individuals by stratified random sampling from a database of 3397 individuals surveyed at New Delhi for the cardiovascular disease surveillance programme in a large industrial setting. Questionnaires assessing details of smoking practices and duration of exposure to ETS (if any) were administered. Cotinine levels were measured in the blood samples of these individuals. The study population comprised 142 nonsmokers not exposed to ETS, 142 non-smokers exposed to ETS and 142 active smokers. Cotinine levels among nonsmokers not exposed to ETS were non-detectable; and for non-smokers exposed to ETS and active smokers, the median (interquartile range) levels were non-detectable (non-detectable to 46.1 ng/ml) and 336 ng/ml (204-500 ng/ml), respectively. The best combined sensitivity (91%) and specificity (87.2%) yielded a cotinine cut-off level of 40.35 ng/ml to differentiate active smokers from non-smokers not exposed to ETS and those exposed to ETS (area under the curve 0.902). The cut-off cotinine level was estimated at 10.95 ng/ml using a similar analysis (sensitivity 43%, specificity 82%; area under the curve 0.64) to distinguish non-smokers not exposed to ETS from those exposed to ETS. The misclassification rate was estimated at 19% and 57.1% among self-reported non-smokers not exposed to ETS and those exposed to ETS, respectively. Obtaining a history of tobacco use is an accurate method of detecting smokers in epidemiological studies whereas serum cotinine levels accurately differentiate smokers from non-smokers. However, a brief questionnaire assessing passive exposure to smoke has poor sensitivity in distinguishing non-smokers exposed to ETS from those not exposed to ETS.

Early Radiographic and Clinical Outcomes Study Evaluating an Integrated Screw and Interbody Spacer for One- and Two-Level ACDF

Lane, Paul D.; Cox, Jacob L.; Gaskins, Roger B.; Billys, James B.; Castellvi, Antonio E.

2015-01-01

Background Multiple techniques and implants can be used in ACDF, the newest of which are integrated cage and screw constructs. These devices may be beneficial over anterior plate constructs due to a negligible anterior profile that may reduce dysphagia. The goal of this study is to review the early radiographical and clinical results associated with a low profile integrated intervertebral cage in one- and two-level anterior column fusions. Methods Fusion rates, incidence of hardware failure and deformity correction were assessed through 1 year. Patientreported scores, including VAS for neck pain, and improvements in axial neck pain and neurologic deficit from the preoperative baseline were quantified at 3, 6 and 12 months post-operatively. The incidence of dysphagia was recorded. Results Lordosis and disc space height at the operated levels increased an average of 4.5° and 3.3mm after device placement (p<0.001). Sagittal plane correction was maintained at 1 year. VAS improved from an average of 5.1 preoperatively to 3.1 immediately postoperatively and was maintained at 12 months. At 3 months, patient-reported improvements in axial neck pain and neurologic deficit were 85% and 93%, respectively. Reported improvements were sustained for both parameters at 12 months (77% and 86%, respectively). Fusion was noted in 93% of the operated levels. There were two documented cases of dysphagia that lasted more than 5 weeks, both following two level ACDFs with the test device (3.5% rate of chronic dysphagia). Conclusions The low profile integrated device improved lordosis at the operated level that was maintained at 1 year. Fusion rates with the new device are consistent with ACDF using anterior plating. In combination with improvements in pain and a minimal rate of dysphagia, study findings support the use of integrated interbody spacers for use in one- and two-level ACDF procedures.

Objectives This study examined mothers’ and fathers’ reporting congruency using the Parent-Child Conflict Tactics Scales. We asked if the mother's report of the father's parenting aggression was consistent with the father's self-report of parenting aggression and if the father's report of the mother's parenting aggression was consistent with the mother's self- report of those same behaviors. We assessed moderators of parental reporting congruency: severity of the aggression, interparental conflict, child temperament, and child gender. Methods Participants were from the Child Development Project, a longitudinal study beginning when children were in kindergarten. The analyses herein included 163 children for whom 2 parents provided data about their own and their spouse or partner's behavior toward the child. Most parents (87%) were married. Mothers and fathers independently completed the Parent-Child Conflict Tactics Scale, both with respect to their own behavior toward the child and with respect to their partner's behavior toward the child. Mothers completed the retrospective Infant Characteristics Questionnaire to assess child temperament. Mothers and fathers completed measures of interparental conflict. Results Both fathers and mothers self-reported more frequently engaging in each behavior than the other parent reported they did. Parents were more congruent on items assessing harsher parenting behavior. Furthermore, there was more agreement between parents regarding fathers’ behavior than mothers’ behavior. Analyses of interparental conflict, child difficult temperament, and child gender as moderators yielded findings suggesting that mothers’ and fathers’ reports of their own and their spouses’ harsh parenting behaviors were more concordant in couples with low levels of conflict, for children with easy temperaments, and for boys versus girls. Conclusions Prior studies indicate only a moderate level of agreement in couples’ reports of violence between intimate partners and suggest that perpetrators tend to underreport their use of aggression. The results of this study suggest that parents may be more consistent in their reports of parent to child violence using the Parent-Child Conflict Tactics Scales than they are when reporting intimate partner violence. The results suggest that parental reports of their spouse's parent to child aggression are reliable. PMID:22763358

To assess the validity of self-reported weight, height, body mass index (BMI), waist circumference and blood pressure compared with standardized clinical measurements and to determine the classification accuracy in overweight/obesity and central adiposity. This pilot study was integrated into a life-course study entitled "Hong Kong Women's Health Study" among 1,253 female nurses in Hong Kong who were aged 35 years to 65 years. Data were collected from self-administered questionnaires that were mailed to the respondents. Of these participants, we obtained the standard body measurements of 144 (11.5%) at our research center. We then compared the self-reported anthropometric variables and blood pressure with the measured data to assess validity based on the level of misreporting, percentage of agreement, consistency, sensitivity and specificity. The self-reported and measured values were highly correlated in terms of anthropometry and blood pressure (correlation coefficients ranged from 0.72 to 0.96). Height was overestimated at an average of 0.42 cm, and waist circumference was underestimated at 2.33 cm (both P<0.05), while no significant differences were observed from weight, blood pressure and BMI (all P>0.05). The proportions of overweight, obesity, and central adiposity by self-reported data did not vary greatly from the measured data (all P>0.05). The self-reporting resulted in correct classifications of BMI, waist circumference, and systolic blood pressure in 85%, 78%, and 87% of women, with corresponding Kappa index values of 0.79, 0.55, and 0.82, respectively. Sensitivity and specificity were 84.6% and 95.7%, respectively, with respect to overweight/obesity detection, whereas those for central adiposity detection were 70.6% and 83.8%, respectively. In a sample of female Hong Kong nurses, the self-reported measures of height, weight, BMI, waist circumference and blood pressure were generally valid. Furthermore, the classification accuracies of overweight/obesity and central adiposity were acceptable.

There is no study that had a sample size sufficient to study the association between sociodemographic and smoking with obesity in Iran. The goal was to investigate these associations in the Iranian women. Multivariate statistical techniques included 14 176 women between 20 and 69 years of age. Height and weight were measured rather than self-reported. In Iranian adult women, obesity OR(S) for the moderate and high education were 0.78 and 0.41, respectively, compared with basic level. Using low economy index as the reference, Obesity OR(S) for the urban women were 1.29, 1.25 and 1.28 for the lower-middle, upper-middle and high groups, respectively. Obesity OR(S) for the rural women were 1.71, 1.71 and 2.02 for the lower-middle, upper-middle and high groups, respectively. Obesity OR was 0.48 for active workforce compared with inactive group. Obesity OR was 0.70 for smokers women compared with nonsmokers. Using non-married as the reference group, Obesity OR(S) were 1.23 and 2.34 for married urban and rural women, respectively. Our results on the associations between age, smoking, education level, workforce and obesity are consistent with most studies, but between economic level and obesity are consistent with some study in developing countries.

Research on virtual reality exposure therapy (VRET) has demonstrated good treatment efficacy with regards to several anxiety disorders. Yet, there is lack of knowledge about the value of integrating interaction between clients and virtual humans in VRET. Such interaction might prove effective in treating psychological complaints that involve social interactions, such as social anxiety. A VRET system specifically designed to expose clients with social anxiety disorder to anxiety provoking social situations was applied to 16 and 18 individuals with high and low levels of social anxiety, respectively. Participants engaged in two exposure sessions in several free speech dialogues with virtual humans while being monitored by a therapist. Participants with high levels of social anxiety reported significantly lower levels of social anxiety three months after exposure to two virtual reality interaction sessions than before treatment (p < 0.01). In the group with low levels of social anxiety, no significant change of social anxiety was reported between pre-treatment and follow-up. Additionally, participants in both groups reported higher self-efficacy three months after treatment than before treatment (ps ≤ 0.001). These findings indicate that virtual reality technology that incorporates social interactions may be successfully applied for therapeutic purposes.

Objectives. We explored the relationship between mental health and type 2 diabetes among women in New Delhi, India, in 2011. Methods. We recruited a convenience sample of 184 diabetic women from 10 public and private clinics. They completed a finger-stick blood test and a questionnaire assessing demographic characteristics, depression and anxiety symptoms, and diabetes-related disabilities restricting their performance of daily tasks. A subsample of 30 women participated in follow-up qualitative interviews at their homes. Results. More than one quarter of our sample of diabetic women reported high levels of anxiety symptoms, whereas 18% reported high levels of depression symptoms. Anxiety symptoms were patterned according to recency of diabetes diagnosis, with 40% of women diagnosed less than 2 years before their interview reporting high anxiety symptom levels, as opposed to 23% of women diagnosed more than 2 years in the past. Depression and anxiety scores differed with respect to their relationship to recency of diagnosis, number of children, blood glucose level, and functional disabilities restricting performance of daily tasks. Conclusions. Screening for anxiety among people with diabetes has been overlooked in the past. Anxiety appears more prevalent than depression, especially during the first 2 years of the disease.

The gabapentinoids pregabalin and gabapentin are being increasingly prescribed for a range of clinical conditions. Recently, although gabapentinoids at therapeutic dosages may present with low addictive liability levels, cases of misuse and rising numbers of related fatalities have been reported. The aim of the study was to identify and assess cases of gabapentinoid misuse or dependence as reported to the European Medicines Agency's EudraVigilance database, to identify the magnitude of this problem and the characteristics of these reactions. All spontaneous reports of both gabapentin- (2004-2015) and pregabalin- (2006-2015) related misuse/abuse/dependence were retrieved. A descriptive analysis by source, sex, age, and type of report was performed. From the EudraVigilance database 7639 (6.6 % of a total of 115,616) and 4301 (4.8 % of 90,166) adverse drug reaction reports of misuse/abuse/dependence were, respectively, associated with pregabalin and gabapentin, with an overall reporting frequency increasing over time. For both molecules, subjects typically involved were female adults. A total of 27 and 86 fatalities, respectively, associated with pregabalin and gabapentin, and mostly in combination with opioids, were identified. Analysis of proportional reporting ratios for drug abuse/dependence/intentional product misuse values seem to indicate that these adverse drug reactions were more frequently reported for pregabalin (1.25, 1.39, and 1.58, respectively) compared with gabapentin. Despite data collection/methodological approach limitations, the present data seem to suggest that gabapentinoid misuse may be a cause for concern, especially in patients with a history of substance misuse. Hence, healthcare professionals should be vigilant when prescribing these molecules.

Objective This study retrospectively examined the daily-level associations between youth alcohol use and dating abuse (DA) victimization and perpetration for a six month period. Method Timeline Followback (TLFB) interview data were collected from 397 urban emergency department patients, ages 17–21 years old. Patients were eligible if they reported past month alcohol use and past year dating. Generalized estimating equation (GEE) analyses estimated the likelihood of DA on a given day as a function of alcohol use or heavy use (≥4 drinks per day for females, ≥5 drinks per day for males), as compared to non-use. Results Approximately 52% of male and 61% of female participants reported experiencing DA victimization ≥1 times during the past six months, and 45% of males and 55% of females reported perpetrating DA ≥1 times. For both males and females, DA perpetration was more likely on a drinking day as opposed to a non-drinking day (ORs 1.70 and 1.69, respectively). DA victimization was also more likely on a drinking day as opposed to a non-drinking day for both males and females (ORs 1.23 and 1.34, respectively). DA perpetration and DA victimization were both more likely on heavy drinking days as opposed to non-drinking days (2.04 and 2.03 for males’ and females’ perpetration, respectively; and 1.41 and 1.43 for males’ and females’ victimization, respectively). Conclusions This study found that alcohol use was associated with increased risk for same day DA perpetration and victimization, for both male and female youth. We conclude that for youth who use alcohol, alcohol use is a potential risk factor for DA victimization and perpetration. PMID:22550149

To formulate individualized dietary strategies for jockeys, it is vital that energy requirements are quantified. We measured total energy expenditure (TEE) over two separate weeks in spring and summer using doubly labelled water in a group of male flat jockeys (n = 8, 36.9 ± 5.7 years, 164 ± 8 cm, 54.6 ± 2.5 kg). Total energy intake (TEI) was self-recorded, as were all riding and structured exercise activity. Mean daily TEE was 10.83 (±2.3) and 10.66 (±1.76) MJ, (p = .61) respectively. Self-reported TEI were 6.03 (±1.7) and 5.37 (±1.1) MJ (p = .40), respectively, and were significantly lower than TEE (p = .01). Mean race rides were 17 (±6) and 13 (±3; p = 0.37) and horses ridden at morning exercise were 8 (±6) and 7 (±4; p = .77) respectively. Additional structured exercise was 76.25 (±95.1) and 52.5 (±80.9) min per week (p = .35), respectively. At the individual level, TEE was related to body mass and the level of non-racing physical activity, but not riding. Physical activity levels for TEE were 1.76 (±0.37) and 1.69 (±0.27; p = .59) and appear modest when compared with other athletes, and similar to age-matched non-athletes, suggesting that conventional sport-specific nutritional recommendations do not appear applicable. The large discrepancy between TEE and TEI suggests significant under reporting of dietary intake. These data now provide an appropriate framework from which to formulate jockey nutritional guidelines to promote the ability to achieve the daily weight target and improve athlete welfare.

This paper reports the results of a 5-year study to evaluate pesticide levels, derived from orchard activities, on Italy's most common orange cultivar (Citrus sinensis, L. Osbeck, cv. Tarocco). Using a Bayesian approach, the study allowed both the qualitative (number) and quantitative distributions (amount) of pesticides to be determined with its own probability value. Multi-residue analyses of 460 samples highlighted the presence of ethyl and methyl chlorpyrifos, dicofol, etofenprox, fenazaquin, fenitrothion, imazalil, malathion and metalaxil-m. A total of 30.5% of samples contained just one pesticide, 2.16% two pesticides and 0.65% of samples had three pesticides present simultaneously. The most common residue was ethyl chlorpyrifos followed by methyl chlorpyrifos. Estimated daily intake (EDI) values for ethyl and methyl chlorpyrifos, as well as the distance from the safety level (non-observed adverse effect level, NOAEL), were calculated. The risk was differentiated (1) to take account of the period of actual citrus consumption (180 days) and (2) to discriminate the risk derived from eating oranges containing a certain level of chlorpyrifos from unspecified pesticides. The most likely EDI values for ethyl chlorpyrifos derived from Italian blood orange consumption are 0.01 and 0.006 mg/day calculated for 180 and 365 days, respectively. Considering the probability of the occurrence of ethyl chlorpyrifos, these EDI values are reduced to 2.6 x 10(-3) and 1.3 x 10(-3) mg/day, respectively. For methyl chlorpyrifos, the most likely EDI values are 0.09 and 0.04 mg/day, respectively; considering the probability of its occurrence, the EDI values decrease to 6.7 x 10(-3) and 3.4 x 10(-3) mg/day, respectively. The results confirmed that levels of pesticides in Italian Tarocco oranges derived from a known controlled chain of production are safe.

Takotsubo cardiomyopathy (TC) is characterised by acute, transient left ventricular apical ballooning precipitated by emotional or physiologically stressful stimuli and has been previously associated with Grave's disease based on a few clinical reports. More recently, the association with exogenous thyrotoxicosis and radioiodine-induced thyroiditis has also been described. Iatrogenic hyperthyroidism on patients on levothyroxine replacement therapy for hypothyroidism has not been reported as a cause of TC. The authors describe two female patients with TC associated with levothyroxine over-replacement. A 74-year-old and a 48-year-old female patient, medicated with levothyroxine (respectively, 2.27 μg/kg and 1.85 μg/kg) for autoimmune thyroiditis were admitted to our emergency room with precordial pain. The first had an electrocardiogram with ST-segment elevation in the anterior precordial leads, and the latter had sinus tachycardia with deep T-wave inversion and QT interval prolongation. Further investigation revealed a mild elevation of cardiac biomarker levels and severe apical hypokinesis, but no significant coronary lesions on catheterisation. The suppressed thyroid stimulating hormone (TSH) levels were verified in the cardiac intensive care unit: 0.21 and 0.07 mIU/l (0.35-5.50) respectively. Both patients showed improvement of the apical hypokinesis on the discharge echocardiogram and normalisation of cardiac biomarker levels. Levothyroxine dose was reduced. This case report focuses on the cardiovascular risks of thyrotoxicosis, emphasises the importance of correct dose adjustment on patients under levothyroxine replacement therapy and stresses that TSH should be determined in patients presenting with acute coronary syndrome and typical findings of TC.

2008-03-01

The construct of empathy was examined in 20 boys with gender identity disorder (GID), 20 clinical control boys with externalizing disorders (ECC), 20 community control boys (NCB), and 20 community control girls (NCG). The mean age of the children was 6.86 years (range = 4-8 years). It was hypothesized that boys with GID would show similar levels of empathy to those shown by NC girls and higher levels of empathy than the NC and ECC boys. Three measures of empathy were administered: a maternal-report questionnaire, a self-report questionnaire, and an in vivo evaluation in which children's reactions to pain simulations to two adult actors (mother, experimenter) were coded for empathy levels. On the maternal report and in-vivo measures, the NC girls had significantly higher empathy levels than the NC boys, but not on the self-report measure. By maternal report, the NC girls were rated as significantly more empathic than were the GID boys, with a "large" effect size. There were no significant differences between the GID boys and the NC girls on the self-report and in-vivo measures and the effect size differences were "small." No significant differences were observed between the GID and NC boys; however, there were "medium" and "small" effect size differences with boys with GID showing more empathy on the in-vivo and self-report measures, respectively. On the maternal-report measure, the GID boys were rated as significantly more empathic than the ECC boys and there was a trend for the GID boys to show greater levels of empathy than the ECC boys on both the self-report and in-vivo measures. The effect size differences on all three empathy measures were "medium" to "large," with GID boys showing more empathy than ECC boys. Empathy as a dispositional characteristic in the genesis and perpetuation of GID in boys is discussed.

Water samples were collected and analyzed for manmade pollutants and naturally occurring constituents. The samples were collected from seven irrigation wells, five domestic wells, two springs, one stock well, two dairy wells, one observation well, and one commercial well. Two quality assurance samples also weremore » collected and analyzed. The water samples were analyzed for selected radionuclides, inorganic constituents, organic compounds, and bacteria. None of the radionuclides, inorganic constituents, or organic compounds exceeded the established maximum contaminant levels for drinking water. Most of the radionuclide and inorganic constituent concentrations exceeded their respective reporting levels. All samples analyzed for surfactants and dissolved organic carbon had concentrations that exceeded their reporting level. Toluene concentrations exceeded the reporting level in one water sample. Two samples contained fecal coliform bacteria counts that exceeded established maximum contaminant levels for drinking water.« less

The Influence of pH and Sodium Hydroxide Exposure Time on Glucosamine and Acrylamide Levels in California-Style Black Ripe Olives.

Acrylic acid, N-acetyl-glucosamine and glucosamine were investigated for their role in the formation of acrylamide in California-style black ripe olives [CBROs]. Levels of acrylic acid and glucosamine are reported for the first time in fresh (333.50 ± 21.88 and 243.59 ± 10.06 nmol/g, respectively) and in brine-stored olives (184.50 ± 6.02 and 165.88 ± 11.51 nmol/g, respectively). Acrylamide levels significantly increased when acrylic acid (35.2%), N-acetyl-glucosamine (29.9%), and glucosamine (124.0%) were added to olives prior to sterilization. However, isotope studies indicate these compounds do not contribute carbon and/or nitrogen atoms to acrylamide. The base-catalyzed degradation of glucosamine is demonstrated in olive pulp and a strong correlation (r 2 = 0.9513) between glucosamine in olives before sterilization and acrylamide formed in processed CBROs is observed. Treatment with sodium hydroxide (pH > 12) significantly reduces acrylamide levels over 1 to 5 d without impacting olive fruit texture. © 2017 Institute of Food Technologists®.

Despite the high prevalence of musculoskeletal disorders seen by primary care physicians, numerous studies have demonstrated deficiencies in the adequacy of musculoskeletal education at multiple stages of medical education. The aim of this study was to assess a newly developed module in musculoskeletal medicine for use at European undergraduate level (i.e., the medical-school level). A two-week module in musculoskeletal medicine was designed to cover common musculoskeletal disorders that are typically seen in primary care. The module incorporated an integrated approach, including core lectures, bedside clinical examination, and demonstration of basic practical procedures. A previously validated examination in musculoskeletal medicine was used to assess the cognitive knowledge of ninety-two students on completion of the module. A historical control group (seventy-two students) from a prior course was used for comparison. The new module group (2009) performed significantly better than the historical (2006) control group in terms of score (62.3% versus 54.3%, respectively; p < 0.001) and pass rate (38.4% versus 12.5%, respectively; p = 0.0002). In a subgroup analysis of the new module group, students who enrolled in the graduate entry program (an accelerated four-year curriculum consisting of students who have already completed an undergraduate university degree) were more likely to perform better in terms of average score (72.2% versus 57%, respectively; p < 0.001) and pass rates (70.9% versus 21.4%, respectively; p < 0.001) compared with students who had enrolled via the traditional undergraduate route. In terms of satisfaction rates, the new module group reported a significantly higher satisfaction rate than that reported by the historical control group (63% versus 15%, respectively; p < 0.001). In conclusion, the musculoskeletal module described in this paper represents an educational advance at undergraduate (i.e., medical-school) level as demonstrated by the improvement in scores in a validated examination. As pressure on medical curricula grows to accommodate advancing medical knowledge, it is important to continue to improve, assess, and consolidate the position of musculoskeletal medicine in contemporary medical education.

The 5-year period of 2005-2009 saw more exertional heat stroke-related deaths in organized sports than any other 5-year period in the past 35 years. The risk of exertional heat stroke appears highest in football, particularly during the preseason. To estimate the incidence of exertional heat stroke events and assess the utilization of exertional heat stroke management strategies during the 2011 preseason in United States high school football programs. Cross-sectional study; Level of evidence, 3. A self-administered online questionnaire addressing the incidence of exertional heat stroke events and utilization of exertional heat stroke management strategies (eg, removing athlete's football equipment, calling Emergency Medical Services [EMS]) was completed in May to June 2012 by 1142 (18.0%) athletic trainers providing care to high school football athletes during the 2011 preseason. Among all respondents, 20.3% reported treating at least 1 exertional heat stroke event. An average of 0.50 ± 1.37 preseason exertional heat stroke events were treated per program. Athletic trainers responding to exertional heat stroke reported using an average of 6.6 ± 1.8 management strategies. The most common management strategies were low-level therapeutic interventions such as removing the athlete's football equipment (98.2%) and clothing (77.8%) and moving the athlete to a shaded area (91.6%). Few athletic trainers reported active management strategies such as calling EMS (29.3%) or using a rectal thermometer to check core body temperature (0.9%). Athletic trainers in states with mandated preseason heat acclimatization guidelines reported a higher utilization of management strategies such as cooling the athlete through air conditioning (90.1% vs 65.0%, respectively; P < .001), immersion in ice water (63.0% vs 45.4%, respectively; P = .01), or fans (54.3% vs 42.0%, respectively; P = .06) and monitoring the athlete's temperature (60.5% vs 46.2%, respectively; P = .04). Preseason exertional heat stroke events, which are likely to be fatal if untreated, were reported by one fifth of all athletic trainers in high school football programs. The standard of care is (and should be) to treat proactively; therefore, treatment is not a perfect proxy for incidence. Nevertheless, there is an urgent need for improved education and awareness of exertional heat stroke in high school football. Areas of improvement include the greatly increased use of rectal thermometers and immersion in ice water.

Obesity, particularly visceral and ectopic adiposity, increases the risk of type 2 diabetes. The aim of this study was to determine if restriction of dietary carbohydrate is beneficial for body composition and metabolic health. Two studies were conducted. In the first, 69 overweight/obese men and women, 53% of whom were European American (EA) and 47% of whom were African American (AA), were provided with 1 of 2 diets (lower-fat diet: 55%, 18%, and 27% of energy from carbohydrate, protein, and fat, respectively; lower-carbohydrate diet: 43%, 18%, and 39%, respectively) for 8 wk at a eucaloric level and 8 wk at a hypocaloric level. In the second study, 30 women with polycystic ovary syndrome (PCOS) were provided with 2 diets (lower-fat diet: 55%, 18%, and 27% of energy from carbohydrate, protein, and fat, respectively; lower-carbohydrate diet: 41%, 19%, and 40%, respectively) at a eucaloric level for 8 wk in a random-order crossover design. As previously reported, among overweight/obese adults, after the eucaloric phase, participants who consumed the lower-carbohydrate vs. the lower-fat diet lost more intra-abdominal adipose tissue (IAAT) (11 ± 3% vs. 1 ± 3%; P < 0.05). After weight loss, participants who consumed the lower-carbohydrate diet had 4.4% less total fat mass. Original to this report, across the entire 16-wk study, AAs lost more fat mass with a lower-carbohydrate diet (6.2 vs. 2.9 kg; P < 0.01), whereas EAs showed no difference between diets. As previously reported, among women with PCOS, the lower-carbohydrate arm showed decreased fasting insulin (-2.8 μIU/mL; P < 0.001) and fasting glucose (-4.7 mg/dL; P < 0.01) and increased insulin sensitivity (1.06 arbitrary units; P < 0.05) and "dynamic" β-cell response (96.1 · 10(9); P < 0.001). In the lower-carbohydrate arm, women lost both IAAT (-4.8 cm(2); P < 0.01) and intermuscular fat (-1.2 cm(2); P < 0.01). In the lower-fat arm, women lost lean mass (-0.6 kg; P < 0.05). Original to this report, after the lower-carbohydrate arm, the change in IAAT was positively associated with the change in tumor necrosis factor α (P < 0.05). A modest reduction in dietary carbohydrate has beneficial effects on body composition, fat distribution, and glucose metabolism. This trial was registered at clinicaltrials.gov as NCT00726908 and NCT01028989. © 2015 American Society for Nutrition.

Extensive research demonstrates the negative impact of maternal depression on their offspring. Unfortunately, few studies have been explored in African American families. This study examined emotional and behavioral functioning among children of African American mothers with depression. African American mothers (n = 63), with a past year diagnosis of a depressive disorder, and one of their children (ages 7-14) completed behavioral rating scales in a cross-sectional design. Results showed that 6.5 and 15% scored within the clinical range for depression and anxiety symptoms, respectively. Approximately a third of the offspring reported suicidal ideation. Based on mothers' report, 25.4 and 20.6% of the offspring exhibited internalizing and externalizing symptoms in the clinical range, respectively. Offspring whose mothers were in treatment exhibited higher levels of self-reported anxiety symptoms. Offspring of African American mothers with depression were exhibiting socioemotional problems in ways that are similar to offspring of European American mothers with depression.

Past research has suggested significant relationships between symptoms and health outcomes among patients with COPD. However, these studies have generally focused on a broad COPD sample and may have included those not receiving proper treatment. As a result, the aim of this study was to document the burden of COPD symptoms among those who are currently treated with the standard-of-care (SOC) medications in both the US and Western Europe. Data from the 2013 US (N=75,000) and 2011 (N=57,512)/2013 (N=62,000) European (France, Germany, Italy, Spain, and UK; 5EU) National Health and Wellness Survey (NHWS) were used. The NHWS is a health survey administered to a demographically representative sample of the adult population in each country. A total of 1,666 and 2,006 patients with self-reported physician diagnosis of COPD in the 5EU and US, respectively, were being treated with the appropriate SOC (based on self-reported medication use) and were included in the analyses. Symptoms (eg, dyspnea, coughing, wheezing) were reported descriptively and summed to create a symptom score (with higher score indicating more frequent symptoms). The relationships between the symptom score and patient outcomes (eg, health status using the Short Form-36 version 2 [SF-36v2], work productivity and activity impairment [WPAI], and self-reported health care resource use) were explored using regression modeling. Nearly all patients (99.7% and 99.8% in the 5EU and US, respectively) reported experiencing symptoms and >80% reported experiencing at least one symptom "often". Increasing symptom scores were associated with poorer health status (unstandardized beta [ b ] =-0.87 and -0.78 for mental component summary and physical component summary, respectively, in the US and b =-0.67 and -0.79 in the 5EU, respectively; all P <0.05). Increasing symptom scores were also associated with greater work impairment ( b =0.09 and 0.06 for the US and 5EU, respectively), activity impairment ( b =0.05 and 0.06, respectively), and health care resource utilization (eg, hospitalizations: b =0.05 and 0.06, respectively) (all P <0.05). Approximately 70% of patients reported some level of non-adherence. Greater non-adherence was significantly associated with more frequent symptoms, poorer health status, and greater work impairment and health care resource use (all P <0.05). Patients with COPD who are using the appropriate SOC still experience symptoms, which have a significant effect on both humanistic and economic outcomes.

This paper reports on the evaluation of the Smart Choices healthy food and drink supply strategy for Queensland schools (Smart Choices) implementation across the whole school environment in state government primary and secondary schools in Queensland, Australia. Three concurrent surveys using different methods for each group of stakeholders that targeted all 1275 school Principals, all 1258 Parent and Citizens' Associations (P&Cs) and a random sample of 526 tuckshop convenors throughout Queensland. Nine hundred and seventy-three Principals, 598 P&Cs and 513 tuckshop convenors participated with response rates of 78%, 48% and 98%, respectively. Nearly all Principals (97%), P&Cs (99%) and tuckshop convenors (97%) reported that their school tuckshop had implemented Smart Choices. The majority of Principals and P&Cs reported implementation, respectively, in: school breakfast programs (98 and 92%); vending machine stock (94 and 83%); vending machine advertising (85 and 84%); school events (87 and 88%); school sporting events (81 and 80%); sponsorship and advertising (93 and 84%); fundraising events (80 and 84%); and sporting clubs (73 and 75%). Implementation in curriculum activities, classroom rewards and class parties was reported, respectively, by 97%, 86% and 75% of Principals. Respondents also reported very high levels of understanding of Smart Choices and engagement of the school community. The results demonstrated that food supply interventions to promote nutrition across all domains of the school environment can be implemented successfully.

The purpose of this study was to identify the cultural climate of southwestern dental colleges, from the perspective of dental hygiene and dental students. The Cultural Attitudes and Climate Questionnaire was used to measure cultural climate. It contained 57 items related to campus experiences, cultural comfort, diversity awareness, racial pressures, fair treatment, respect, lack of support, patient care and overall satisfaction. The survey was administered to 508 dental and dental hygiene students at 5 dental colleges. The response rate was 41% (n=239/508). Students reported not experiencing racial conflict or pressures (71 to 90%), being treated fairly and with respect (86 to 90%) and being comfortable interacting with and treating other cultures (70 to 91%). They also practiced culturally appropriate behaviors (54 to 92%). Those reporting diversity training (77.8%) were more likely to engage in 3 of the 6 awareness practices (p<0.033). Although all groups agreed their educational experience was rewarding (89.5%), African-Americans reported a significantly lower level of agreement than Whites (p=0.003) and Asians (p=0.008). Among all groups, satisfaction with their educational experience was significantly correlated with fair treatment (rho=0.441 to 0.511, p<0.001) and respect for other cultures (rho=0.391 to 0.441, p<0.001). The students generally reported a positive cultural climate. Improvements could be made by focusing on fair treatment, respect for cultures and the African-American experience. Cultural competence training could be key to improving cultural climate, as positive outcomes from training were identified. Copyright © 2015 The American Dental Hygienists’ Association.

The toxicological assessments of 2 grab sample canisters (GSCs) and one pair of formaldehyde badges from the Shuttle are reported. Analytical methods have not changed from earlier reports. The recoveries of the 3 surrogates (C-13-acetone, fluorobenzene, and chlorobenzene) from the 2 GSCs averaged 120, 117, and 122 %, respectively. Three formaldehyde controls averaged 98% recovery. The Shuttle atmosphere was acceptable for human respiration. The toxicological assessment of 8 GSCs and 6 pairs of formaldehyde badges from the ISS is shown. The recoveries of the 3 standards (as listed above) from the GSCs averaged 99, 99 and 99%, respectively. Three formaldehyde control badges averaged 98% recovery. Based on these limited samples, the ISS atmosphere is acceptable for human respiration. The alcohol levels were well controlled throughout the period of sampling.

Background The study objective was to compare children’s oral health related quality of life (OHRQoL) in schools with 6 years of implementation of a health promoting school model in Malaysia, i.e. the Doktor Muda Programme (DMP) and in schools without the DMP. Methods This report was part of a larger study to evaluate the DMP impact on schoolchildren’s oral health knowledge, attitudes, behaviour, caries progression and OHRQoL. It was conducted in Negri Sembilan state. The sample comprised 3455, Year 6 (11–12 year old) children; 1282 from DMP (intervention) and 2173 from non-DMP (control) schools. The Malay Child-OIDP index was used to evaluate children’s levels of oral impacts on 8 daily performances after 6 years of DMP implementation (2006–2011). Prevalence, score, impact intensity, causes and extent of impacts were compared. Chi-square and Mann–Whitney tests were used in the data analysis. Results Overall response rate was 95.1%. Prevalence of overall impacts was 57.8% and 60.8% (mean total impact score was 7.10 and 7.77) in the intervention and control group, respectively. The three most frequently affected performances in both groups were eating, cleaning teeth and emotional stability. Significantly less DMP children had oral impact on cleaning teeth (p = 0.034). The majority of children with impacts in both groups reported ‘very little’ to ‘moderate’ levels of impact intensity. Significantly more DMP children reported having ‘very little’ and ‘little’ levels of impact intensity on cleaning teeth (p = 0.037) and emotional stability (p = 0.020), respectively. Significantly less DMP children reported having ‘very severe’ level of impact intensity on speaking (p = 0.038). The most prevalent cause of impacts in both groups was toothache. Significantly less DMP children reported bleeding gums (p = 0.016) and presence of plaque/calculus as causes of impacts (p = 0.032). About 75% of children with impacts in both groups reported having up to four daily performances affected. Conclusion This study showed that the health promoting school model, i.e. the Doktor Muda Programme for primary schools in Malaysia had some positive impacts on 11–12 year old children’s oral health related quality of life.

Many epidemiological and experimental studies report a strong role of chemical carcinogens in the etiology of bladder cancer. However, the involvement of heavy metals in tumourigenesis of urothelial carcinoma of the bladder has been poorly investigated. Therefore, the aim of this study was to examine the relationship between chromium (Cr) and bladder cancer. Chromium concentration in two 36-sample series of bladder cancer tissue and sera from patients with this neoplasm were matched with those of a control group. The amount of trace elements in every tissue sample was determined using atomic absorption spectrometry. This was correlated with tumour stage. While the median chromium concentration levels reached statistically higher values in the bladder cancer tissue, compared with the non-cancer tissue (99.632ng/g and 33.144ng/g, respectively; p<0.001), the median Cr levels in the sera of the patients with this carcinoma showed no statistical difference when compared to those of the control group (0.511μg/l and 0.710μg/l, respectively; p=0.408). The median levels of Cr in the bladder tissue, depending on the stage of the tumour, compared with the tissue without the neoplasm, observed the same relationship for both non-muscle invasive and muscle-invasive tumours (p<0.001 and p<0.01, respectively). This study shows that patients with urothelial carcinoma of the bladder had higher tissue Cr levels than people without tumour, while no difference was found in the Cr serum levels between the two groups of patients under investigation.

Intra-articular cellular therapy injections constitute an appealing strategy that may modify the intra-articular milieu or regenerate cartilage in the settings of osteoarthritis and focal cartilage defects. However, little consensus exists regarding the indications for cellular therapies, optimal cell sources, methods of preparation and delivery, or means by which outcomes should be reported. We present a systematic review of the current literature regarding the safety and efficacy of cellular therapy delivered by intra-articular injection in the knee that provided a Level of Evidence of III or higher. A total of 420 papers were screened. Methodological quality was assessed using a modified Coleman methodology score. Only 6 studies (4 Level II and 2 Level III) met the criteria to be included in this review; 3 studies were on treatment of osteoarthritis and 3 were on treatment of focal cartilage defects. These included 4 randomized controlled studies without blinding, 1 prospective cohort study, and 1 retrospective therapeutic case-control study. The studies varied widely with respect to cell sources, cell characterization, adjuvant therapies, and assessment of outcomes. Outcome was reported in a total of 300 knees (124 in the osteoarthritis studies and 176 in the cartilage defect studies). Mean follow-up was 21.0 months (range, 12 to 36 months). All studies reported improved outcomes with intra-articular cellular therapy and no major adverse events. The mean modified Coleman methodology score was 59.1 ± 16 (range, 32 to 82). The studies of intra-articular cellular therapy injections for osteoarthritis and focal cartilage defects in the human knee suggested positive results with respect to clinical improvement and safety. However, the improvement was modest and a placebo effect cannot be disregarded. The overall quality of the literature was poor, and the methodological quality was fair, even among Level-II and III studies. Effective clinical assessment and optimization of injection therapies will demand greater attention to study methodology, including blinding; standardized quantitative methods for cell harvesting, processing, characterization, and delivery; and standardized reporting of clinical and structural outcomes.

Reports of acute turpentine intoxication, particularly containing toxicological data, are poorly verified in the literature. This report regards the intentional massive ingestion of turpentine solution in an elderly woman who developed mainly central nervous system manifestations, then had an impressive and quick total recovery although the initial prognosis was very bad. Blood and urine levels of turpentine were monitored using gas chromatography and at the early toxicogenic stage were 28 micrograms/mL and 15 micrograms/mL respectively. Gastric fluid analysis on admission to the hospital revealed the presence of approximately 200 mL turpentine in the intestine. A review of earlier reports is given.

Liquefied petroleum gas (LPG) poisoning: report of two cases and review of the literature.

Two autopsy cases of men who died while connecting a liquefied petroleum gas (LPG) pipe are reported. Their blood concentrations of propane (the main content of LPG) were 0.12 and 3.40 mg/100 g, respectively. The cause of death after exposure of LPG has generally been considered to be asphyxia from hypoxia. The large differences in the blood propane levels found here and reported in the literature, however, suggest that direct toxic effects of propane poisoning may be the cause of death in some cases. Propane concentrations and the cause of death are reviewed and discussed.

Health inequalities by socioeconomic characteristics in Spain: the economic crisis effect.

An economic crisis can widen health inequalities between individuals. The aim of this paper is to explore differences in the effect of socioeconomic characteristics on Spaniards' self-assessed health status, depending on the Spanish economic situation. Data from the 2006-2007 and 2011-2012 National Health Surveys were used and binary logit and probit models were estimated to approximate the effects of socioeconomic characteristics on the likelihood to report good health. The difference between high and low education levels leads to differences in the likelihood to report good health of 16.00-16.25 and 18.15-18.22 percentage points in 2006-07 and 2011-12, respectively. In these two periods, the difference between employees and unemployed is 5.24-5.40 and 4.60-4.90 percentage points, respectively. Additionally, the difference between people who live in households with better socioeconomic conditions and those who are in worse situation reaches 5.37-5.46 and 3.63-3.74 percentage points for the same periods, respectively. The magnitude of the contribution of socioeconomic characteristics to health inequalities changes with the economic cycle; but this effect is different depending on the socioeconomic characteristics indicator that is being measured. In recessive periods, health inequalities due to education level increase, but those linked to individual professional status and household living conditions are attenuated. When the joint effects of individuals' characteristics are considered, the economic crisis brings about a slight increase in the inequalities in the probability of reporting good health between the two extreme profiles of individuals. The design of public policies aimed at preventing any worsening of health inequalities during recession periods should take into account these differential effects of socioeconomic characteristics indicators on health inequalities.

Many observational studies indicate higher oral contraceptive failure among obese women, but most clinical trials and physiologic studies do not support these differences. Limited data indicate higher failure rates among obese contraceptive patch users. Data regarding contraceptive vaginal ring performance in obese women are needed. Twenty normal weight (body mass index [BMI] 19.0-24.9; median, 21.65) and 20 obese (BMI 30.0-39.9; median, 33.7) women enrolled in a prospective study of ethinyl estradiol (EE(2)) and etonorgestrel pharmacokinetics and of ovarian follicle development, endometrial thickness, and bleeding patterns, all measured biweekly during the second cycle of contraceptive vaginal ring use. Thirty-seven women completed follow-up. Mean day 0-21 EE(2) concentrations were lower among obese vs normal weight women (15.0 vs 22.0 pg/mL, respectively, P = .004), whereas etonorgestrel concentrations were similar (1138 vs 1256 pg/mL, respectively, P = .39). Follicular development was minimal in both groups, with only 5 women achieving a maximum follicle diameter >13 mm at any time during 3 weeks follow-up (3 normal weight and 2 obese women); these women had serum progesterone levels <1.0. Obese women reported more bleeding or spotting than normal weight women (3.6 vs 1.4 days, respectively, P = .01). Although obese women had lower EE(2) levels during contraceptive vaginal ring use, they had excellent suppression of ovarian follicle development, similar to normal weight women. This predicts that contraceptive vaginal ring effectiveness will be similar in women with a BMI up to 39.9. The lower serum EE(2) levels in the obese women may explain the greater reported bleeding or spotting days. Copyright © 2012 Mosby, Inc. All rights reserved.

Objectives: The aim of this study was to obtain information about senior dental students’ perceptions and self-confidence levels regarding endodontic practice. Materials and Methods: Anonymous survey forms were handed out to senior students at Yeditepe University, Faculty of Dentistry. The students were asked to score their level of confidence using a 5-point scale and comment about future practices. Results: The response rate of the survey was 88%. 11.9% expressed endodontics as the first branch in terms of difficulty. The majority (90.5%) indicated they would perform root canal treatments within their expertise limit in the future but refer difficult cases to an endodontist. Bleaching of endodontically treated teeth, managing flare-ups, placement of a rubber dam were procedures in which students reported the lowest confidence (2.55 ± 1.17, 3.24 ± 0.96, 3.24 ± 1.19, respectively). On the other hand, students felt the lowest confidence in the treatment of maxillary molars followed by mandibular molars (3.43 ± 1.02 and 3.93 ± 0.97, respectively). Students also reported the lowest confidence in root resorptions, endo-perio lesions, traumas, retreatments and apexifications (2.93 ± 1.16, 3.07 ± 0.89, 3.24 ± 0.85, 3.33 ± 1.7 and 3.36 ± 1.1, respectively). Conclusions: The results showing students’ lower confidence in more challenging aspects of dentistry may be related with the attitude of dental schools to refer these cases to post graduate students and instilling information about these cases on a theoretical basis only. Though there seems to be a tendency for students to refer challenging cases to a specialist in future, authorities should give priority to enhance the way information and experience is conveyed regarding various aspects of endodontic treatment.

Although it is well established that all the aspects of male reproduction are hormonally regulated, the endocrine control of the ejaculatory reflex is still not completely clarified. Sex steroids, thyroid and pituitary hormones (oxytocin and prolactin) have been proposed to control the ejaculatory process at various levels; however, only a few reports are currently available. The aim of this study was to evaluate the contribution of testosterone, thyrotropin (TSH) and prolactin (PRL) in the pathogenesis of ejaculatory dysfunction in a large series of subjects consulting for sexual dysfunction. Among the 2652 patients studied, 674 (25.2%) and 194 (7.3%) reported premature and delayed ejaculation (PE and DE), respectively. Categorizing ejaculatory difficulties on an eight-point scale starting from severe PE and ending with anejaculation (0 = severe PE, 1 = moderate PE, 2 = mild PE, 3 = no difficulties, 4 = mild DE, 5 = moderate DE, 6 = severe DE and 7 = anejaculation), PRL as well as TSH levels progressively increased from patients with severe PE towards those with anejaculation. Conversely, the opposite was observed for testosterone levels. All of these associations were confirmed after adjustment for age (adjusted r = 0.050, 0.053 and -0.038 for PRL, TSH and testosterone, respectively; all p < 0.05). When all hormonal parameters were introduced in the same regression model, adjusting for age, ΣMHQ (an index of general psychopathology) and use of selective serotonin reuptake inhibitor antidepressants, they were independently associated with ejaculatory problems (adjusted r = 0.056, 0.047 and -0.059 for PRL, TSH and testosterone, respectively; all p < 0.05). This study indicates endocrine system is involved in the control of ejaculatory function and that PRL, TSH and testosterone play an independent role. © 2010 The Authors.

Integrating plant ecological responses to climate extremes from individual to ecosystem levels.

PubMed

Felton, Andrew J; Smith, Melinda D

2017-06-19

Climate extremes will elicit responses from the individual to the ecosystem level. However, only recently have ecologists begun to synthetically assess responses to climate extremes across multiple levels of ecological organization. We review the literature to examine how plant responses vary and interact across levels of organization, focusing on how individual, population and community responses may inform ecosystem-level responses in herbaceous and forest plant communities. We report a high degree of variability at the individual level, and a consequential inconsistency in the translation of individual or population responses to directional changes in community- or ecosystem-level processes. The scaling of individual or population responses to community or ecosystem responses is often predicated upon the functional identity of the species in the community, in particular, the dominant species. Furthermore, the reported stability in plant community composition and functioning with respect to extremes is often driven by processes that operate at the community level, such as species niche partitioning and compensatory responses during or after the event. Future research efforts would benefit from assessing ecological responses across multiple levels of organization, as this will provide both a holistic and mechanistic understanding of ecosystem responses to increasing climatic variability.This article is part of the themed issue 'Behavioural, ecological and evolutionary responses to extreme climatic events'. © 2017 The Author(s).

We reported previously that blood levels of nicotine in suicidal smokers tend to be significantly higher than those in non-suicidal smokers, and blood level of nicotine seems to be a useful criterion for discriminating suicide from other types of death. In this paper, we report nicotine and cotinine levels in various tissues of an adipocere body found in the sea. The cause of death was drowning, and the postmortem time interval was approximately 5 months at autopsy. His driver's license was concealed in his sock, which seemed to suggest that he committed to suicide. In toxicological analysis by gas chromatography, nicotine and cotinine in the femoral muscle were detected at concentrations of 213 and 488 ng/g, respectively, and these substances were also detected in the brain, liver and kidney. For evaluating the tissue levels of nicotine and cotinine in the adipocere body, we analyzed these levels in blood and various tissues of 13 autopsy cases of smokers. Nicotine and cotinine levels in blood were the most similar to those in skeletal muscle. Although the postmortem time interval, the formation process of adipocere and the environmental condition in water may affect nicotine and cotinine levels in the femoral muscle, the high muscle level of nicotine in the present case seem to implicate suicidal death.

Calcineurin inhibitors (CNIs) have become the cornerstone of immunosuppressive regimens following heart transplantation, but their use is associated with nephrotoxicity. The impact on renal function after conversion from cyclosporine (CsA) to tacrolimus (TAC) is reported. Fifteen patients (men age 42 +/- 11 years) after cardiac transplantation (HTX) were switched from CsA to TAC (mean time after HTX 21 +/- 6 months). There were 13 male and 2 female patients. Mean cholesterol and LDL level at the time of conversion were 217 +/- 65 ml/dl and and 136 +/- 51 mg/100 ml respectively. Indication for HTX was ischemic cardiomyopathy (CMP) in 8, congenital in 3 and dilatative CMP in the remaining 4 patients. Mean tacrolimus level (microg/dl) at 1, 3, 6 and 12 months were 8.6 +/- 3.3, 8.6 +/- 1.4, 9.2 +/- 2.8 and 9.8 +/- 2.5 respectively. There was a statistically significant improvement in creatinine levels at 1, 3, 6 and 12 months after conversion from baseline 1.9 +/- 0.7 mg/dl to 1.4 +/- 0.5 mg/dl, 1.4 +/- 0.4 mg/dl, 1.3 +/- 0.4 mg/dl and 1.2 +/- 0.4 mg/dl, respectively (p < 0.05). Furthermore, TAC decreased cholesterol as well as LDL-levels during this one-year time frame. This study shows that conversion from CsA to tacrolimus after orthotopic heart transplantation improves renal function.

Aquatic ecosystems of the Bolivian Altiplano (∼3800 m a.s.l.) are characterized by extreme hydro-climatic constrains (e.g., high UV-radiations and low oxygen) and are under the pressure of increasing anthropogenic activities, unregulated mining, agricultural and urban development. We report here a complete inventory of mercury (Hg) levels and speciation in the water column, atmosphere, sediment and key sentinel organisms (i.e., plankton, fish and birds) of two endorheic Lakes of the same watershed differing with respect to their size, eutrophication and contamination levels. Total Hg (THg) and monomethylmercury (MMHg) concentrations in filtered water and sediment of Lake Titicaca are in the lowest range of reported levels in other large lakes worldwide. Downstream, Hg levels are 3-10 times higher in the shallow eutrophic Lake Uru-Uru than in Lake Titicaca due to high Hg inputs from the surrounding mining region. High percentages of MMHg were found in the filtered and unfiltered water rising up from <1 to ∼50% THg from the oligo/hetero-trophic Lake Titicaca to the eutrophic Lake Uru-Uru. Such high %MMHg is explained by a high in situ MMHg production in relation to the sulfate rich substrate, the low oxygen levels of the water column, and the stabilization of MMHg due to abundant ligands present in these alkaline waters. Differences in MMHg concentrations in water and sediments compartments between Lake Titicaca and Uru-Uru were found to mirror the offset in MMHg levels that also exist in their respective food webs. This suggests that in situ MMHg baseline production is likely the main factor controlling MMHg levels in fish species consumed by the local population. Finally, the increase of anthropogenic pressure in Lake Titicaca may probably enhance eutrophication processes which favor MMHg production and thus accumulation in water and biota.

People who smoke crack cocaine and people who inject drugs are at-risk for criminal justice involvement as well as HIV and HCV infection. Compared to criminal justice involvement, substance use treatment (SUT) can be cost-effective in reducing drug use and its associated health and social costs. We conducted a cross-sectional study of people who smoke crack cocaine and people who inject drugs to examine the association between incarceration, community supervision and substance use treatment with HIV/HCV testing, components of the HIV treatment cascade, social and physical vulnerability and risk behavior. Targeted sampling methods were used to recruit people who smoke crack cocaine and people who inject drugs (N = 2072) in Oakland, California from 2011 to 2013. Poisson regression models were used to estimate adjusted prevalence ratios between study exposures and outcomes. The overall HIV prevalence was 3.3% (95% CI 2.6-4.1). People previously experiencing incarceration were 21% (p < 0.001) and 32% (p = 0.001), respectively, more likely to report HIV and HCV testing; and were not more likely to report receiving HIV care or initiating ART. People previously experiencing community supervision were 17% (p = 0.001) and 15% (p = 0.009), respectively, more likely to report HIV and HCV testing; and were not more likely to report receiving HIV care or initiating ART. People with a history of SUT were 15% (p < 0.001) and 23% (p < 0.001), respectively, more likely to report receiving HIV and HCV testing, 67% (p = 0.016) more likely to report HIV care, and 92% (p = 0.012) more likely to report HIV treatment initiation. People previously experiencing incarceration or community supervision were also more likely to report homelessness, trouble meeting basic needs and risk behavior. People with a history of substance use treatment reported higher levels of HCV and HIV testing and greater access to HIV care and treatment among HIV-positive individuals. People with a history of incarceration or community supervision reported higher levels of HCV and HIV testing, but not greater access to HIV care or treatment among HIV-positive individuals., Substance use treatment programs that are integrated with other services for HIV and HCV will be critical to simultaneously address the underlying reasons drug-involved people engage in drug-related offenses and improve access to essential medical services.

To study recall of mobile phone usage, including laterality and hands-free use, in young people. Actual mobile phone use was recorded among volunteers aged between 10 and 24 years from 12 countries by the software application XMobiSense and was compared with self-reported mobile phone use at 6 and 18 months after using the application. The application recorded number and duration of voice calls, number of text messages, amount of data transfer, laterality (% of call time the phone was near the right or left side of the head, or neither), and hands-free usage. After data cleaning, 466 participants were available for the main analyses (recorded vs. self-reported phone use after 6 months). Participants were on average 18.6 years old (IQR 15.2-21.8 years). The Spearman correlation coefficients between recorded and self-reported (after 6 months) number and duration of voice calls were 0.68 and 0.65, respectively. Number of calls was on average underestimated by the participants (adjusted geometric mean ratio (GMR) self-report/recorded = 0.52, 95% CI = 0.47-0.58), while duration of calls was overestimated (GMR=1.32, 95%, CI = 1.15-1.52). The ratios significantly differed by country, age, maternal educational level, and level of reported phone use, but not by time of the interview (6 vs. 18 months). Individuals who reported low mobile phone use underestimated their use, while individuals who reported the highest level of phone use were more likely to overestimate their use. Individuals who reported using the phone mainly on the right side of the head used it more on the right (71.1%) than the left (28.9%) side. Self-reported left side users, however, used the phone only slightly more on the left (53.3%) than the right (46.7%) side. Recorded percentage hands-free use (headset, speaker mode, Bluetooth) increased with increasing self-reported frequency of hands-free device usage. Frequent (≥50% of call time) reported headset or speaker mode use corresponded with 17.1% and 17.2% of total call time, respectively, that was recorded as hands-free use. These results indicate that young people can recall phone use moderately well, with recall depending on the amount of phone use and participants' characteristics. The obtained information can be used to calibrate self-reported mobile use to improve estimation of radiofrequency exposure from mobile phones. Copyright © 2018 Elsevier Inc. All rights reserved.

Associations between shift work (SW) schedules, mental distress and job satisfaction have never been completely described. To examine gender-specific associations of SW with mental distress and job satisfaction in nurses in Hebron District, Palestine, in 2012. Detailed information on work schedules (day versus shift), socio-demographic status, mental distress (General Health Questionnaire, GHQ-30) and job satisfaction (Generic Job Satisfaction Scale) in nurses employed in Hebron District, Palestine, was obtained through a questionnaire survey. Associations of SW and outcomes were examined by linear regression analysis. Of 372 nurses eligible for the study, 309 and 338 completed surveys regarding mental distress and job satisfaction, respectively. The sample comprised 62% women and 38% men. After adjusting for covariates, women working shifts reported significantly higher levels of mean mental distress [β coefficient 3.6; 95% confidence interval (CI) 0.3-7.0] compared with women working regular day shifts. Men working shifts reported significantly lower levels of job satisfaction (-3.3; 95% CI -6.2 to -0.5) than men working regular day shifts. Women reported higher levels of mental distress than men, but this was unrelated to work schedule. In this study, nurses working shifts reported higher levels of mental distress and lower levels of job satisfaction, although these associations were weaker when adjusted for potential covariates. There was no evidence of a gender differential in the association between SW and mental distress and job satisfaction. © The Author 2016.

Mantwill, Sarah; Schulz, Peter J

2017-04-01

To compare functional health literacy (HL) levels in three immigrant groups to those of the German- and Italian-speaking non-immigrant population in Switzerland. Moreover, to investigate whether language-independent, respectively language-dependent, functional HL and variables of acculturation were associated with self-reported health status among immigrants. Language-independent HL was assessed with the Short Test of Functional Health Literacy (S-TOFHLA) in the respective native languages. Language-dependent HL was measured using Brief Health Literacy Screeners (BHLS) asking about participants' confidence in understanding medical information in the language of the host country. Measures of acculturation included length of stay and age when taking residency in Switzerland. In particular Albanian- and Portuguese-speaking immigrants had lower levels of functional HL. In unadjusted analysis "age when taking residency in Switzerland" was associated with the BHLS. Adjusted analysis showed that the BHLS were significantly associated with self-reported health among all immigrant groups (p≤0.01). Functional HL that is dependent on understanding of medical information in the language of the new host country is a better predictor for self-reported health status among immigrants than language-independent HL. In the clinical setting limited functional HL might be a significant obstacle to successful disease treatment and prevention in immigrants. Copyright © 2016 Elsevier Ireland Ltd.

We reported two cases of hyperthyroidism that developed during induction chemotherapy for advanced germ cell tumors with high serum human chorionic gonadotropin (hCG) levels. Case 1 : An 18-year-old man with mediastinal choriocarcinoma complained of tachycardia and tremor. His pretreatment serum hCG level was 1.37 million mIU/ml. The free thyroxine (fT4) level measured on day 2 of the first course of bleomycin, etoposide and cisplatin (BEP) was elevated to 7.8 ng/dl (＜1.7 ng/dl), whereasthe thyroidstimulating hormone (TSH) level was undetectable. We diagnosed the patient with hyperthyroidism and started oral propranolol and thiamazole. Subsequently, his tachycardia and tremor disappeared. On day 12 of the first course of BEP, his hCG level decreased to less than 50,000 mIU/ml. Also, his fT4 level returned to the normal range. Case 2 : A 29-year-old man presented with a left scrotal mass. He was diagnosed with non-seminoma testicular cancer (embryonal carcinoma and choriocarcinoma) with multiple lung, liver and lymph node metastases. On the admission day, his serum hCG and fT4 levels were high ; 3.23 million mIU/ml and 2.2 ng/dl, respectively. The TSH level was low at 0.011 mIU/ml. On day 3 of the first course of BEP, his hCG and fT4 levels increased to 4.5 million mIU/ml and 3.0 ng/dl, respectively. He complained of tachycardia, tremor and hyperhydrosis. He was started on propranolol and potassium iodide. After the treatment, histachycardia, tremor and hyperhidrosisdis appeared. HisfT4 level normalized on day 17 of the first course of BEP. The TSH-like activity of hCG is considered to be responsible for paraneoplastic hyperthyroidism among germ cell cancer patients with high hCG levels. To our knowledge, thisisthe first report of such a case in Japan. However, thisphenomenon isnot rare among patients with extremely high hCG levels. Therefore, we should be careful of these patients.

Contextual moderators of momentary cortisol and negative affect in adolescents' daily lives.

PubMed

Doane, Leah D; Zeiders, Katharine H

2014-05-01

To use an ecological momentary assessment design to examine the links between momentary negative affect and cortisol in a sample of adolescents preparing to transition to college. Guided by a risk and resilience framework, we also explored whether important ecological factors, perceived discrimination and social support, moderated the momentary associations between negative affect and youths' cortisol. Adolescents (N = 77) provided salivary samples and diary reports of affect and experiences five times a day over 3 days. They also completed self-report questionnaires on perceived discrimination and social support from family and friends. Within-person increases in momentary negative affect were associated with increases in cortisol. Perceived discrimination and social support from friends moderated this association. Adolescents who reported average and high levels of perceived discrimination experienced exaggerated cortisol responses to negative affect, whereas adolescents who reported low levels of perceived discrimination did not experience significant reactivity to negative affect. In contrast, adolescents who reported high levels of social support from friends experienced attenuated cortisol responses to negative affect compared with adolescents who reported average or low levels of social support from friends. This study contributes to our understanding of youths' daily socioemotional experiences and physiological reactivity by identifying how perceived discrimination and social support from friends amplified and attenuated, respectively, the effects of negative affect on cortisol reactivity. Examining these processes within adolescents' naturalistic environments advances our understanding of the moderating role of ecological characteristics in adolescents' everyday lives.

Although well-being and psychophysical health of nursery school and kindergarten teachers have important implications also on the health and well-being of their recipients, studies dedicated to these workers are quite rare, particularly in Italy. The aim of the study was to observe psychophysical health conditions in a sample of nursery school and kindergarten teachers employed in the Education Services Division of the Municipality of Turin. The study was cross-sectional; 884 self-reporting questionnaires were distributed and 734 teachers (representing 53% of those employed at the Education Services of the Municipality of Turin) correctly filled out the questionnaire. Respectively 53.4% and 50% of participants reported medium or high levels of emotional exhaustion and depersonalization, while 18.5% showed low levels of personal accomplishment. Responders reported moderate levels of work ability in 38.9% and poor levels in 5.6%. The majority of the respondents (98.7%) did not report depressive symptoms; 42.9% of the sample suffered moderate to severe limiting musculoskeletal pain. Age and profession were associated with emotional exhaustion, personal accomplishment, and musculoskeletal pain. However, work ability and depression were only associated with age. No associations were found with depersonalization. The present study shows that health conditions of nursery school and kindergarten teachers were critical and that age contributed to the explanation of these conditions.

Potentiometric surface of the Upper Floridan aquifer, west-central Florida, September 2010

Ortiz, A.G.

2011-01-01

This report, prepared by the U.S. Geological Survey in cooperation with the Southwest Florida Water Management District, is part of a semi-annual series of Upper Floridan aquifer potentiometric-surface map reports for west-central Florida. Potentiometric surface maps have been prepared for January 1964, May 1969, May 1971, May 1973, May 1974, and for each May and September since 1975. Water-level data are collected in May and September each year to show the approximate annual low and high water-level conditions, respectively. This map report shows the potentiometric surface of the Upper Floridan aquifer measured in September 2010. The potentiometric surface is an imaginary surface connecting points of equal altitude to which water will rise in tightly-cased wells that tap a confined aquifer system (Lohman, 1979). This map represents water-level conditions near the end of the wet season, when groundwater levels usually are at an annual high and withdrawals for agricultural use typically are low. The cumulative average rainfall of 53.17 inches for west-central Florida (from October 2009 through September 2010) was 0.41 inches above the historical cumulative average of 52.76 inches (Southwest Florida Water Management District, 2010). Historical cumulative averages are calculated from regional rainfall summary reports (1915 to most recent complete calendar year) and are updated monthly by the Southwest Florida Water Management District.

To evaluate the role of parathyroid hormone (PTH) and serum calcium in prediction for hypocalcaemia after total thyroidectomy. One hundred and sixty-five patients undergoing total or complete total thyroidectomy were reviewed retrospectively. The indications included bilateral carcinoma, undifferential carcinoma, surroundings invasion, distant metastasis and huge benign lesions. Preoperative and postoperative PTH, calcium concentrations and their decline levels were compared between Jan. 2005 and May 2009. The role of PTH value and decline level predicting for symptomatic hypocalcaemia were analyzed by receiver operator characteristics (ROC) curve. After total thyroidectomy, 85 patients (51.5%) developed hypocalcemia. Symptoms were reported by 36 patients (21.8%). The mean concentration of PTH for normocalcaemia (80 cases), asymptomatic hypocalcaemia (49 cases) and symptomatic patients (36 cases) were 31.0 ng/L, 19.6 ng/L and 11.9 ng/L, respectively. The mean decline level for the three groups were 28.6%, 52.6% and 78.0%, respectively. PTH value and its decline level had a poor predicting value for symptomatic hypocalcaemia and high negative predicting value for asymptomatic patients. The serum calcium concentration more than 2.0 mmol/L, PTH level higher than 15 ng/L and PTH decline less than 50% had the good negative predicting value of 97.6%, 90.3% and 96.5%, respectively. Postoperative PTH and its decline level were significantly correlated with postoperative serum calcium concentration but had a low accuracy for predicting symptomatic hypocalcaemia. The serum calcium concentration more than 2.0 mmol/L, PTH level higher than 15 ng/L and PTH decline less than 50% had the good predicting value for asymptomatic patients. Calcium should be routinely supplemented in the first 24 h after total thyroidectomy to reduce the rate of hypocalcemia and the severity of hypocalcemia symptoms.

The relationship between reported childhood maltreatment and general psychological and post-traumatic distress was examined in a sample of 551 adults from different risk samples. Exposure to childhood maltreatment was assessed using the Childhood Trauma Questionnaire Short Form, which detects physical, emotional and sexual abuse and past physical and emotional neglect. The participants' current levels of post-traumatic stress symptoms and general psychological stress symptoms were measured with the Impact of Event Scale - Revised and the Symptom Checklist 90 - Revised, respectively. The results reveal a high prevalence of reported childhood maltreatment in both men and women, and the severity levels of the five types of childhood maltreatment showed significant associations with the extent of current post-traumatic and general psychological distress. The findings emphasize the need for appropriate procedures for identifying childhood maltreatment.

Consumer and case manager perspectives of service empowerment: relationship to mental health recovery.

PubMed

Crane-Ross, Dushka; Lutz, Wilma J; Roth, Dee

2006-04-01

This study examines the relationship between service empowerment and recovery. Service empowerment is defined as the extent to which consumers participate in service decisions and the level of reciprocity and respect within the relationship with their case managers. Assessments were made from two perspectives: consumers and their case managers. Structural equation models were developed to examine the direct and indirect effects of service empowerment on four recovery outcomes: Quality of Life, Level of Functioning, Consumer-Reported Symptomatology, and Case Manager-Reported Symptomatology. Consumers' perceptions of service empowerment were the most powerful predictor of recovery outcomes across the four models. Consumers' and case managers' perceptions were related but the magnitude of the relationship was small, indicating that considerable differences exist between their perceptions of service empowerment.

Background Comprehensive evidence exists regarding the discrepancy between children's reports and parents' by proxy reports on emotional and behavioural problems. However, little is yet known about factors influencing the extent to which child self- and parent by proxy reports differ in respect of child Quality of Life (QoL). The aim of the study was to investigate the degree of discrepancy between child and parent by proxy reports as measured by two different QoL instruments. Methods A representative Norwegian sample of 1997 school children aged 8–16 years, and their parents were studied using the Inventory of Life Quality (ILC) and the 'Kinder Lebensqualität Fragebogen' (KINDL). Child and parent reports were compared by t-test, and correlations were calculated by Pearson product moment coefficient. Psychometric aspects were examined in regard to both translated QoL instruments (internal consistency by Cronbach's alpha and test-retest reliability by intraclass correlation coefficients). Results Parents evaluated the QoL of their children significantly more positively than did the children. Correlations between mother-child and father-child reports were significant (p < 0.01) and similar but low to moderate (r = 0.32; and r = 0.30, respectively, for the KINDL, and r = 0.30 and r = 0.26, respectively, for the ILC). Mother and father reports correlated moderately highly (r = 0.54 and r = 0.61 for the KINDL and ILC, respectively). No significant differences between correlations of mother-daughter/son and father-daughter/son pairs in regard to reported child QoL were observed on either of the two instruments. Conclusion In the present general population sample, parents reported higher child QoL than did their children. Concordance between child and parent by proxy report was low to moderate. The level of agreement between mothers and fathers in regard to their child's QoL was moderate. No significant impact of parent and child gender in regard to agreement in ratings of child QoL was found. Both the child and parent versions of the Norwegian translations of the KINDL and ILC can be used in surveys of community populations, but in regard to the self-report of 9–10 years old children, only the KINDL total QoL scale or the ILC are recommended.

Background Studies report frequent micronutrient deficiencies after bariatric surgery, but less is known about micronutrient levels of pregnant women after bariatric surgery. Objective To prospectively evaluate micronutrient levels and supplement intake in pregnancy following bariatric surgery. Design A multicenter prospective cohort study including women with restrictive or malabsorptive types of bariatric surgery. Nutritional deficiencies, together with supplement intake, were screened during pregnancy. Results The total population included 18 women in the restrictive and 31 in the malabsorptive group. Most micronutrients were depleted and declined significantly during pregnancy. The proportion of women with low vitamin A and B-1 levels increased to respectively 58 and 17% at delivery (P = 0.005 and 0.002). The proportion of women with vitamin D deficiency decreased from 14% at trimester 1 to 6% at delivery (P = 0.030). Mild anemia was found in respectively 22 and 40% of the women at trimester 1 and delivery. In the first trimester, most women took a multivitamin (57.1%). In the second and third trimester, the majority took additional supplements (69.4 and 73.5%). No associations were found between supplement intake and micronutrient deficiencies. Conclusion Pregnant women with bariatric surgery show frequent low micronutrient levels. Supplementation partially normalizes low levels of micronutrients. PMID:25470614

HIV infection may be affected by multiple complex socioeconomic status (SES) factors, especially individual socioeconomic disadvantage and community-level inequality. At the same time, stigma towards HIV and marginalized groups has exacerbated persistent concentrated epidemics among key populations, such as persons who inject drugs (PWID) in Vietnam. Stigma researchers argue that stigma fundamentally depends on the existence of economic power differences in a community. In rapidly growing economies like Vietnam, the increasing gap in income and education levels, as well as an individual's absolute income and education, may create social conditions that facilitate stigma related to injecting drug use and HIV. A cross-sectional baseline survey assessing different types of stigma and key socioeconomic characteristics was administered to 1674 PWID and 1349 community members living in physical proximity throughout the 32 communes in Thai Nguyen province, Vietnam. We created four stigma scales, including HIV-related and drug-related stigma reported by both PWID and community members. We then used ecologic Spearman's correlation, ordinary least-squares regression and multi-level generalized estimating equations to examine community-level inequality associations, individual-level SES associations and multi-level SES associations with different types of stigma, respectively. There was little urban-rural difference in stigma among communes. Higher income inequality was marginally associated with drug-related stigma reported by community members (p=0.087), and higher education inequality was significantly associated with higher HIV-related stigma reported by both PWID and community members (p<0.05). For individuals, higher education was significantly associated with lower stigma (HIV and drug related) reported by both PWID and community members. Part-time employed PWID reported more experiences and perceptions of drug-related stigma, while conversely unemployed community members reported enacting lower drug-related stigma. Multi-level analysis revealed that the relationship between education inequality and HIV-related stigma is superseded by the effect of individual-level education. The results of the study confirm that socioeconomic factors at both the individual level and community level affect different types of stigma in different ways. Attention should be paid to these differences when planning structural or educational interventions to reduce stigma, and additional research should investigate the mechanisms with which SES and inequality affect social relationships and, in turn, stigma.

Part-time employed PWID reported more experiences and perceptions of drug-related stigma, while conversely unemployed community members reported enacting lower drug-related stigma. Multi-level analysis revealed that the relationship between education inequality and HIV-related stigma is superseded by the effect of individual-level education. Conclusions The results of the study confirm that socioeconomic factors at both the individual level and community level affect different types of stigma in different ways. Attention should be paid to these differences when planning structural or educational interventions to reduce stigma, and additional research should investigate the mechanisms with which SES and inequality affect social relationships and, in turn, stigma.

To apply Karasek's Job Content Model to an analysis of the relationships between job type and perceived stress and stress behaviors in a large company during a period of reorganization and downsizing. Cross-sectional mail-out, mail-back survey. A large Canadian telephone/telecommunications company. Stratified random sample (stratified by job category) of 2200 out of 13,000 employees with a response rate of 48.8%. Responses to 25 of Karasek's core questions were utilized to define four job types: low-demand and high control = "relaxed"; high demand and high control = "active"; low demand and low control = "passive", and high demand and low control = "high strain." These job types were compared against self-reported stress levels, perceived general level of health, absenteeism, alcohol use, exercise level, and use of medications and drugs. Similar analyses were performed to assess the influence of shift work. Employees with "passive" or "high strain" job types reported higher levels of stress (trend test p < .0001); poorer health (trend test P = .006); and higher levels of absenteeism (trend test p < .0001). More shift workers reported themselves in poor or fair health (chi-square p = .018) and reported high levels of stress at home (chi-square p = .002) than nonshift workers. The relationships between job type and levels of stress, health and absenteeism, however, held for nonshift workers as well. Job types with high demand and low control were associated with increased stress, increased absenteeism, and poorer self-concept of health. The demand/control model of Karasek and Theorell was validated in this setting with respect to stress and some stress-associated attitudes and behaviors.

Aim: To report the Karnataka Internet Assisted Diagnosis of Retinopathy of Prematurity (KIDROP) program for retinopathy of prematurity (ROP) screening in underserved rural areas using an indigenously developed tele-ROP model. Materials and Methods: KIDROP currently provides ROP screening and treatment services in three zones and 81 neonatal units in Karnataka, India. Technicians were trained to use a portable Retcam Shuttle (Clarity, USA) and validated against ROP experts performing indirect ophthalmoscopy. An indigenously developed 20-point score (STAT score) graded their ability (Level I to III) to image and decide follow-up based on a three-way algorithm. Images were also uploaded on a secure tele-ROP platform and accessed and reported by remote experts on their smart phones (iPhone, Apple). Results: 6339 imaging sessions of 1601 infants were analyzed. A level III technician agreed with 94.3% of all expert decisions. The sensitivity, specificity, positive predictive value and negative predictive value for treatment grade disease were 95.7, 93.2, 81.5 and 98.6 respectively. The kappa for technicians to decide discharge of babies was 0.94 (P < 0.001). Only 0.4% of infants needing treatment were missed. The kappa agreement of experts reporting on the iPhone vs Retcam for treatment requiring and mild ROP were 0.96 and 0.94 (P < 0.001) respectively. Conclusions: This is the first and largest real-world program to employ accredited non-physicians to grade and report ROP. The KIDROP tele-ROP model demonstrates that ROP services can be delivered to the outreach despite lack of specialists and may be useful in other middle-income countries with similar demographics.

The National Chlamydia Screening Programme performs 1.7 million tests annually among young adults in England. The effect of chlamydia screening on subsequent behavior is unknown. This study examined the self-reported impact of testing on young adults' subsequent health care-seeking and sexual behavior. We conducted a cross-sectional Web-based anonymous survey using an online panel to recruit 1521 young adults aged 16 to 24 years and resident in England. Survey questions were developed using the theory of planned behavior. Multivariate log-binomial regression was used to identify the variables associated with an impact on subsequent behavior after testing. Most respondents reported that being tested for chlamydia had a positive effect on their subsequent sexual behavior (68.6%; 422/615) or health care-seeking behavior (80.0%; 492/615). In multivariate analysis, being female and having a high level of engagement at last test were both associated with positive impacts on sexual behavior (72.7% [adjusted prevalence ratio {aPR}, 1.19; 95% confidence interval {CI}, 1.07-1.33] and 82.7% [aPR, 1.55; 95% CI, 1.27-1.89], respectively), and health care-seeking behavior (84.4% [aPR, 1.13; 95% Cl, 1.04-1.24] and 86.3% [aPR, 1.23; 95% CI, 1.07-1.41], respectively). Among respondents with minimum level of engagement, 72.4% (76/105) reported an increase in subsequent health care-seeking behavior. Chlamydia testing had a positive impact on young adults' self-reported health care-seeking and sexual behavior. This suggests that chlamydia screening has a wider effect on young adults' sexual health beyond that of treatment alone.

Prevalence and incidence rates of lipodystrophy vary widely and frequently rely upon self- and/or clinician reports. Currently no validated assessment tool for facial lipoatrophy is available. To illustrate that assessment of the severity of facial lipoatrophy by patients and clinicians is subjective. To evaluate the reproducibility of facial three-dimensional surface laser scans. Twenty-three HIV-positive men were recruited from an inner London HIV outpatient clinic in September 2001. CD4 count, viral load, antiretroviral history and body mass index were recorded. Patients and clinicians independently assessed the severity of facial lipoatrophy on a four-point scale and the level agreement was measured. Seventeen of the 23 patients (73.9%) underwent two scans 1 week apart, which were then superimposed. The volume difference (mm3) and mean difference (mm) between the scans for five regions of the face were measured and compared with the self-reported grade of facial lipoatrophy. For each pair of clinicians (P=0.03, 0.005 and 0.0002, respectively), and for one patient-clinician pair (P=0.004), there was a significant systematic difference between the two sets of gradings of facial lipoatrophy. The level of disagreement was generally higher for patients reporting facial lipoatrophy (n=17) compared to those not reporting it (n=6). The mean volume difference and mean difference between any region were within 200 mm3 and 0.25 mm, respectively. Reproducibility was unaffected by the self-reported grade of facial lipoatrophy. Assessment of the severity of facial lipoatrophy by patients and clinicians is subjective. Three-dimensional facial laser scans are reproducible and may provide an objective tool for monitoring changes in facial lipoatrophy.

Despite reports of improved awareness of breast cancer entity and seemingly upbeat levels of other awareness subthemes in Nigeria, patients continue to present late when treatment is least rewarding. This paradoxical trend of both rising awareness and late presentation coupled with reports suggesting other competing drivers of late presentation question the "theory of poor awareness" as the foremost driver of late presentations. By aggregating available data, we aimed to assess what still constitutes poor breast cancer awareness in Nigeria in order to suggest how to allocate resources to reverse the paradox. Studies conducted on Nigerian populace from 2000 to date were reviewed systematically. Search was made in PROSPERO, PubMed/MEDLINE, AJOL, Cochrane library, GOOGLE, ResearchGate and ACADEMIA. Primary outcome was level of awareness about breast cancer entity. Fifty-one eligible (48 descriptive surveys, 3 interventional ones) studies were reviewed. They included 19,598 respondents (98.5% females; 43% rural dwellers). 17,086(87.2%) were laypersons in various walks of life; 2,512(12.8%) were healthcare professionals. There were high levels of awareness of breast cancer entity, BSE, knowledge of fatality and benefit of early detection (weighted percentages 80.6%, 60.1%, 73.2% and 73.9% respectively). Weighted percentages of knowledge of symptoms/signs was 45.1%. Weighted percentages of sense of susceptibility and performance of BSE were low-26.8% and 22.9% respectively. Generally, rate of performance of screening did not vary with changes in the level of awareness/knowledge of concepts. In general, low awareness of breast cancer may not be the direct and foremost driver of persistent late presentation in Nigeria.

Personal inhalation exposure samples were collected and analyzed for polycyclic aromatic hydrocarbons (PAHs) for 126 selected volunteers during heating and non-heating seasons in a typical northern Chinese city, Taiyuan. Measured personal PAH exposure levels for the urban residents in the heating and non-heating seasons were 690 (540-1051) and 404 (266-544) ng/m(3) , respectively, while, for the rural residents, they were 770 (504-1071) and 312 (201-412) ng/m(3) , respectively. Thus, rural residents are exposed to lower PAH contamination in comparison with the urban residents in the non-heating seasons. In the heating season, personal PAH inhalation exposure levels were comparable between the urban and rural residents, in part owing to the large rate of residential solid fuel consumption in the rural area for household cooking and heating. The estimated incremental lifetime cancer risks (ILCR) due to PAH exposure in Taiyuan were 3.36 × 10(-5) and 2.39 × 10(-5) for the rural and urban residents, respectively, significantly higher than the literature-reported national average level, suggesting an urgent need of PAH pollution control to protect human health. © 2014 John Wiley & Sons A/S.

Variations in ankle injury rates and distributions among competition levels are unclear, but such data may help inform strategies to prevent ankle sprains during American football. To describe the epidemiological patterns of ankle sprains in youth, high school (HS), and collegiate American football. Descriptive epidemiological study. Data regarding youth, HS, and college football athletes were collected from 3 injury surveillance programs: (1) the Youth Football Safety Study (YFSS), (2) the National Athletic Treatment, Injury and Outcomes Network (NATION), and (3) the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP). During the 2012-2014 seasons, the YFSS, NATION, and NCAA ISP included 310, 184, and 71 football team-seasons, respectively. Athletic trainers (ATs) attended each practice and game and reported injuries and athlete-exposures (AEs) via their preferred injury documentation application. Ankle sprain rates for each type of ankle sprain were calculated overall, by event type (ie, practices and games), and specifically for severe injuries (ie, participation restriction time >21 days) and recurrent injuries (as defined by ATs). Rate ratios (RRs) were used to compare ankle sprain rates by competition level and event type. Injury proportion ratios (IPRs) were used to compare differences in severity, surgical needs, recurrence, injury mechanism, and injury activity by competition level. RRs and IPRs with 95% confidence intervals excluding 1.00 were considered statistically significant. A total of 124, 897, and 643 ankle sprains were reported in youth, HS, and college football, respectively. This led to respective rates of 0.59, 0.73, and 1.19 sprains per 1000 AEs. The ankle sprain rate in college football was higher than the rates in HS (RR = 1.64; 95% CI, 1.48-1.82) and youth (RR = 2.01; 95% CI, 1.65-2.43) football. The proportion of ankle sprains that were recurrent in youth football was higher than the proportions in HS (IPR = 2.73; 95% CI, 1.68-4.50) and college (IPR = 2.19; 95% CI, 1.33-3.61) football. Ankle sprain rates were highest in college athletes. However, level-specific variations in ankle sprain severity and recurrence may highlight the need to develop level-specific policies and prevention strategies to reduce injury incidence.

The number of systematic reviews published in the orthopaedic literature has increased, and these reviews can help guide clinical decision making. However, the quality of these reviews can affect the reader's ability to use the data to arrive at accurate conclusions and make clinical decisions. To evaluate the methodological and reporting quality of systematic reviews and meta-analyses in the sports medicine literature to determine whether such reviews should be used to guide treatment decisions. The hypothesis was that many systematic reviews in the orthopaedic sports medicine literature may not follow the appropriate reporting guidelines or methodological criteria recommended for systematic reviews. Systematic review. All clinical sports medicine systematic reviews and meta-analyses from 2009 to 2013 published in The American Journal of Sports Medicine (AJSM), The Journal of Bone and Joint Surgery (JBJS), Arthroscopy, Sports Health, and Knee Surgery, Sports Traumatology, Arthroscopy (KSSTA) were reviewed and evaluated for level of evidence according to the guidelines from the Oxford Centre for Evidence-Based Medicine, for reporting quality according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, and for methodological quality according to the Assessment of Multiple Systematic Reviews (AMSTAR) tool. Analysis was performed by year and journal of publication, and the levels of evidence included in the systematic reviews were also analyzed. A total of 200 systematic reviews and meta-analyses were identified over the study period. Of these, 53% included evidence levels 4 and 5 in their analyses, with just 32% including evidence levels 1 and 2 only. There were significant differences in the proportion of articles with high levels of evidence (P < .001) and low levels of evidence (P = .005) by journal. The average PRISMA score was 87% and the average AMSTAR score was 73% among all journals. The average AMSTAR and PRISMA scores were significantly different by journal (P = .002 and .001, respectively) and by year (P = .046 and .019, respectively). Arthroscopy, AJSM, and JBJS all scored higher than Sports Health and KSSTA on the PRISMA and AMSTAR. The average PRISMA score by year varied from 85% to 89%, and the average AMSTAR score varied from 70% to 76%. Systematic reviews and meta-analyses in orthopaedics sports medicine literature relied on evidence levels 4 and 5 in 53% of studies over the 5-year study period. Overall, PRISMA and AMSTAR scores are high and may be better than those in other disciplines. Readers need to be conscious of potential shortcomings when reading systematic reviews and using them in practice. © 2015 The Author(s).

Validity of parent-reported weight and height of preschool children measured at home or estimated without home measurement: a validation study

PubMed Central

2011-01-01

Background Parental reports are often used in large-scale surveys to assess children's body mass index (BMI). Therefore, it is important to know to what extent these parental reports are valid and whether it makes a difference if the parents measured their children's weight and height at home or whether they simply estimated these values. The aim of this study is to compare the validity of parent-reported height, weight and BMI values of preschool children (3-7 y-old), when measured at home or estimated by parents without actual measurement. Methods The subjects were 297 Belgian preschool children (52.9% male). Participation rate was 73%. A questionnaire including questions about height and weight of the children was completed by the parents. Nurses measured height and weight following standardised procedures. International age- and sex-specific BMI cut-off values were employed to determine categories of weight status and obesity. Results On the group level, no important differences in accuracy of reported height, weight and BMI were identified between parent-measured or estimated values. However, for all 3 parameters, the correlations between parental reports and nurse measurements were higher in the group of children whose body dimensions were measured by the parents. Sensitivity for underweight and overweight/obesity were respectively 73% and 47% when parents measured their child's height and weight, and 55% and 47% when parents estimated values without measurement. Specificity for underweight and overweight/obesity were respectively 82% and 97% when parents measured the children, and 75% and 93% with parent estimations. Conclusions Diagnostic measures were more accurate when parents measured their child's weight and height at home than when those dimensions were based on parental judgements. When parent-reported data on an individual level is used, the accuracy could be improved by encouraging the parents to measure weight and height of their children at home. PMID:21736757

To study the activity and incidence of knee pain after sustaining an isolated tibia fracture treated with an infrapatellar intramedullary nail at 1 year. Retrospective review of prospective cohort. Multicenter Academic and Community hospitals. Four hundred thirty-seven patients with an isolated tibia fracture completed a 12-month assessment on pain and self-reported activity. Infrapatellar intramedullary nail. Demographic information, comorbid conditions, injury characteristics, and surgical technique were recorded. Knee pain was defined on a 1-7 scale with 1 being "no pain" and 7 being a "very great deal of pain." Knee pain >4 was considered clinically significant. Patients reported if they were "able," "able with difficulty," or "unable" to perform the following activities: kneel, run, climb stairs, and walk prolonged. Variables were tested in multilevel multivariable regression analyses. In knee pain, 11% of patients reported a "good deal" to a "very great deal" of pain (>4), and 52% of patients reported "no" or "very little" pain at 12 months. In activity at 12 months, 26% and 29% of patients were unable to kneel or run, respectively, and 31% and 35% of patients, respectively, stated they were able with difficulty or unable to use stairs or walk. Clinically significant knee pain (>4/7) was present in 11% of patients 1 year after a tibia fracture. Of note, 31%-71% of patients had difficulty performing or were unable to perform routine daily activities of kneeling, running, and stair climbing, or walking prolonged distances.

Despite the frequent co-ocurrence of hypermobile Ehler-Danlos syndrome (hEDS) and pathological anxiety, little is known about the psychosocial and health implications of such comorbidity. Our aim was to explore the association between high levels of anxiety and psychosocial (catastrophizing, kinesiophobia, somatosensory amplification, social support and functioning), health (pain, fatigue, BMI, tobacco/alcohol use, depression, diagnosis delay, general health), and sociodemographic factors in people with hEDS. In this cross-sectional study, 80 hEDS patients were divided into two groups according to self-reported anxiety levels: low and high. Psychosocial, sociodemographic and health variables were compared between the groups. Forty-one participants reported a high level of anxiety (51.2%). No differences were found in the sociodemographic variables between high-anxious and low-anxious patients. The percentage of participants with severe fatigue and high depressive symptomatology was significantly higher in the high-anxious group (80.5 vs 56.4; 26.8 vs 12.8%, respectively). High-anxious hEDS patients also showed significantly higher levels of pain catastrophizing, somatosensory amplification as well as a poorer social functioning and general health. Multivariate analyses showed that somatosensory amplification, pain catastrophizing and poor social functioning are variables that increase the probability of belonging to the high-anxious group. Despite limitations, this first study comparing high-anxious versus low-anxious hEDS patients with respect to health aspects, highlight the importance of considering the psychosocial factors (many susceptible to modification), to improve the adjustment to this chronic condition and provide support to those affected through a biopsychosocial approach.

It is during Medical Residency Training (MIR) that knowledge, abilities and habits are acquired, which will shape professional activity in the future. It is therefore very likely that residents who do not acquire the necessary habits and knowledge for research activities will eventually not carry out these activities in the future. The aim of this study was to analyze the level of satisfaction of residents with his or her scientific and research training, and to determine any deficiencies with respect to this training. The aim of the questionnaire used was to determine the level of satisfaction of residents regarding their scientific and research training during their residency period. Questionnaires were usually distributed via internal mail to all residents (MIR physicians) registered at a third level teaching hospital, with a completion rate of 78% (n = 178). As far as the evaluation of scientific training is concerned, 68% of residents were dissatisfied or very dissatisfied. With respect to scientific studies carried out, 49% of residents had not taken part in any, but the number of studies carried out increases as the residency progresses. On the other hand, 22% of residents reported not having started their doctoral thesis, 50% having attended doctorate courses, 24% having a title for their thesis, and only 4% having written a thesis. Doctorate courses, thesis topics, and written theses increase with the year of residency, and a greater activity may be seen in this respect in surgical departments. If we analyze help available to residents for their carrying out scientific activities, 55% reported that only selected assistant doctors would offer help, and 21% reported that no doctors would offer help. Dissatisfaction with research training increases with the year of residency. With regard to main specialist fields, it can be seen that residents in surgical fields carry out more theses, whereas central fields report less facilities. Finally, if we evaluate the influence that these variables may have on the general satisfaction of residents with his or her residency, these variables are seen to be significant factors of dissatisfaction. Most residents are dissatisfied with their scientific training and have relatively few facilities for developing such skills, which in turn results in a scarce number of scientific studies and doctoral theses.

From an environmental perspective, the underground metro system is one of the cleanest forms of public transportation in urban agglomerations. Current studies report contradicting results regarding air quality in the metro systems: whereas some reveal poor air quality, others report PM levels which are lower or of the same order of magnitude than those measured in traffic sites above ground level. The present work assesses summer and winter indoor air quality and passenger exposure in the Barcelona metro, focusing on PM levels and their metal contents. In addition, the impact on indoor air quality of platform screen door systems (automated systems consisting of closed rail track and platforms) is evaluated, to determine whether these systems reduce passenger exposure to PM when compared with conventional systems (open tracks and platforms). In the Barcelona metro PM levels inside the trains in summer are amongst the lowest reported for worldwide metro systems (11-32 μg m-3 PM2.5). This is most likely due to the air conditioning system working in all carriages of the Barcelona metro during the whole year. Levels were considerably higher on the platforms, reaching mean levels of 46 and 125 μg m3 in the new (L9) and old (L3) lines, respectively. PM10 data are also reported in the present study, but comparison with other metro systems is difficult due to the scarcity of data compared with PM2.5. Results showed distinct PM daily cycles, with a drastic increase from 06:00 to 07:00 a.m., a diurnal maximum from 07:00 to 10:00 p.m., and marked decrease between 10:00 p.m. and 05:00 a.m. The elements with the highest enrichment were those associated with wheel or brake abrasion products (Ba, Fe, Cu, Mn, Cr, Sb, As, Mo, Co, Sr, among others). Laminar hematite (Fe2O3) was the dominant particle type, being mainly originated by mechanical abrasion of the rail track and wheels. Regarding passenger exposure to PM, the contribution of commuting by metro was estimated to account for around 10% of the daily exposure. However, this contribution may be one order of magnitude higher when specific matals are considered. Finally, we conclude that the implementation of platform screen door systems results in reductions of both PM levels and metal concentrations. In addition an advanced optimized ventilation system gave even a much higher efficiency in reducing exposure to PM of metro commuters. Combining these two features PM exposure levels in the platforms may be reduced down by a factor of 7 with respect the old subway lines in Barcelona.

Objective: To determine dose-dependent effects of T administration on voice changes in women with low T levels. Methods: Seventy-one women who have undergone a hysterectomy with or without oophorectomy with total T < 31 ng/dL and/or free T < 3.5 pg/mL received a standardized transdermal estradiol regimen during the 12-week run-in period and were then randomized to receive weekly im injections of placebo or 3, 6.25, 12.5, or 25 mg T enanthate for 24 weeks. Total and free T levels were measured by liquid chromatography-tandem mass spectrometry and equilibrium dialysis, respectively. Voice handicap was measured by self-report using a validated voice handicap index questionnaire at baseline and 24 weeks after intervention. Functional voice testing was performed using the Kay Elemetrics-Computer Speech Lab to determine voice frequency, volume, and harmonics. Results: Forty-six women with evaluable voice data at baseline and after intervention were included in the analysis. The five groups were similar at baseline. Mean on-treatment nadir total T concentrations were 13, 83, 106, 122, and 250 ng/dL in the placebo, 3-, 6.25-, 12.5-, and 25-mg groups, respectively. Analyses of acoustic voice parameters revealed significant lowering of average pitch in the 12.5- and 25-mg dose groups compared to placebo (P < .05); these changes in pitch were significantly related to increases in T concentrations. No significant dose- or concentration-dependent changes in self-reported voice handicap index scores were observed. Conclusion: Testosterone administration in women with low T levels over 24 weeks was associated with dose- and concentration-dependent decreases in average pitch in the higher dose groups. These changes were seen despite the lack of self-reported changes in voice. PMID:25875779

To determine dose-dependent effects of T administration on voice changes in women with low T levels. Seventy-one women who have undergone a hysterectomy with or without oophorectomy with total T < 31 ng/dL and/or free T < 3.5 pg/mL received a standardized transdermal estradiol regimen during the 12-week run-in period and were then randomized to receive weekly im injections of placebo or 3, 6.25, 12.5, or 25 mg T enanthate for 24 weeks. Total and free T levels were measured by liquid chromatography-tandem mass spectrometry and equilibrium dialysis, respectively. Voice handicap was measured by self-report using a validated voice handicap index questionnaire at baseline and 24 weeks after intervention. Functional voice testing was performed using the Kay Elemetrics-Computer Speech Lab to determine voice frequency, volume, and harmonics. Forty-six women with evaluable voice data at baseline and after intervention were included in the analysis. The five groups were similar at baseline. Mean on-treatment nadir total T concentrations were 13, 83, 106, 122, and 250 ng/dL in the placebo, 3-, 6.25-, 12.5-, and 25-mg groups, respectively. Analyses of acoustic voice parameters revealed significant lowering of average pitch in the 12.5- and 25-mg dose groups compared to placebo (P < .05); these changes in pitch were significantly related to increases in T concentrations. No significant dose- or concentration-dependent changes in self-reported voice handicap index scores were observed. Testosterone administration in women with low T levels over 24 weeks was associated with dose- and concentration-dependent decreases in average pitch in the higher dose groups. These changes were seen despite the lack of self-reported changes in voice.

Domain-specific database applications tend to contain a sizable number of table-, form-, and report-style views that must each be designed and maintained by a software developer. A significant part of this job is the necessary tweaking of low-level presentation details such as label placements, text field dimensions, list or table styles, and so on. In this paper, we present a horizontally constrained layout management algorithm that automates the display of structured hierarchical data using the traditional visual idioms of hand-designed database UIs: tables, multi-column forms, and outline-style indented lists. We compare our system with pure outline and nested table layouts with respect to space efficiency and readability, the latter with an online user study on 27 subjects. Our layouts are 3.9 and 1.6 times more compact on average than outline layouts and horizontally unconstrained table layouts, respectively, and are as readable as table layouts even for large datasets.

Background Widespread residential pesticide use throughout the United States has resulted in ubiquitous, low-level pesticide exposure. The mix of active pesticide ingredients is changing in response to 2000–2001 regulations restricting use of the organophosphorus insecticides chlorpyrifos and diazinon. Objectives We aimed to determine the impact of U.S. Environmental Protection Agency regulations on pest infestation levels, pesticide use, and pesticides measured in indoor air samples. METHODOLOGY: 511 pregnant women from innercity New York were enrolled between 2000 and 2006. Permethrin, a pyrethroid insecticide; piperonyl butoxide (PBO), a pyrethroid synergist; chlorpyrifos; and diazinon were measured in 48-hr prenatal personal air samples. Data on pest infestation and pesticide use were collected via questionnaire. Results Eighty-eight percent of women reported using pesticides during pregnancy; 55% reported using higher-exposure pesticide applications (spray cans, pest bombs and/or professional pesticide applicators). Self-reported pest sightings and use of higher-exposure applications increased significantly after the regulations were implemented (p < 0.001). PBO, cis-, and trans-permethrin were detected in 75, 19, and 18% of personal air samples, respectively. Detection frequencies of PBO and cis- and trans-permethrin increased significantly over time (p < 0.05 controlling for potential confounders). Levels and/or detection frequencies of these compounds were significantly higher among mothers reporting use of high exposure pesticide applications (p ≤ 0.05). Chlorpyrifos and diazinon levels decreased significantly over time (p < 0.001). Conclusion In this cohort, pest infestations, use of pesticides, and use of permethrin appear to increase after the residential restriction of organophosphorus insecticides. This is one of the first studies to document widespread residential exposure to PBO. PMID:19079720

Many studies use questionnaires to determine smoking status and age of smoking onset. This study aimed to determine the reliability of self-reported smoking history and age of smoking initiation. The proportion of inconsistent answers and correlation coefficients of reported age of initial smoking were measured by an answer-reanswer analysis of questionnaires in an ongoing, two-step, population-based survey of health behavior. Interviews were conducted on the day of recruitment to and the day of discharge from mandatory military service in Israel among a sample of 25,437 young men and women recruited between 1986 and 2000. Of 7276 participants reporting current or past smoking upon recruitment, 559 (7.7%) reported never having smoked upon discharge, thus demonstrating prima facie inconsistency. Variables significantly associated with reliable reporting in a multivariate logistic regression model were female gender (P = 0.04) and more than 4 years of military service (P < 0.01). 6010 subjects who reported a positive smoking history at both recruitment and discharge were available for analysis of reliability of reported age at smoking onset. Intraclass correlation coefficients for recruitment/discharge consistency in reported age at first cigarette were 0.73 (95% CI: 0.71-0.74) and 0.76 (95% CI: 0.74-0.78) for men and women, respectively. Eastern origin, lower subject education level, and lower paternal education level were also associated with lower reliability. Our results showed a relatively high level of answer-reanswer reliability, with some variance attributable to personal characteristics. These results suggest that self-reported age at onset of tobacco use is practical and reliable in normative, young adult populations. However, time elapsed between questionnaires and demographic and lifestyle characteristics may affect reliability rates, and thus should be carefully regarded in future studies.

Objectives To determine the prevalence of cardiovascular disease, levels of cardiovascular risk factors, and extent of preventive care in Gullah African Americans with a high familial risk of type 2 diabetes mellitus. Methods Between 1995 and 2003, 1321 Gullah African Americans with a high prevalence of diabetes mellitus from the South Carolina Sea Islands consented to and enrolled in the Sea Islands Genetic African American Registry (Project SuGAR). A cross-sectional analysis of cardiometabolic risk, preventive care, and self-reported cardiovascular disease was conducted. Results Cardiometabolic risk factor levels were high and vascular disease was prevalent. Among the subjects with diabetes mellitus, the mean disease duration was 10.5 years; approximately one-third reported reduced vision or blindness; and >80% reported numbness, pain, or burning in their feet. Preventive diabetes care was limited, with <60%, <25%, and <40% seeing an ophthalmologist, podiatrist, and dentist, respectively, within the past year. Only 54.4% of women and 39.3% of men reported daily glucose monitoring. Conclusions As the largest existing study of Gullah individuals, our study offers insight into not only the level of cardiovascular risk in this population but also the pathophysiological mechanisms central to ancestral differences in cardiometabolic risk in the broader African American population.

Patient-Reported Expanded Disability Status Scale (PREDSS) tools are an attractive alternative to the Expanded Disability Status Scale (EDSS) during long term or geographically challenging studies, or in pressured clinical service environments. Because the studies reporting these tools have used different metrics to compare the PREDSS and EDSS, we undertook an individual patient data level analysis of all available tools. Spearman's rho and the Bland-Altman method were used to assess correlation and agreement respectively. A systematic search for validated PREDSS tools covering the full EDSS range identified eight such tools. Individual patient data were available for five PREDSS tools. Excellent correlation was observed between EDSS and PREDSS with all tools. A higher level of agreement was observed with increasing levels of disability. In all tools, the 95% limits of agreement were greater than the minimum EDSS difference considered to be clinically significant. However, the intra-class coefficient was greater than that reported for EDSS raters of mixed seniority. The visual functional system was identified as the most significant predictor of the PREDSS-EDSS difference. This analysis will (1) enable researchers and service providers to make an informed choice of PREDSS tool, depending on their individual requirements, and (2) facilitate improvement of current PREDSS tools. © The Author(s), 2015.

Due to the family-centric nature of Hungarian society and to the high proportion of women in the medical profession, more female than male physicians may experience work-family conflict. The authors hypothesized that work-family conflict may reduce job satisfaction among female physicians. However, there is limited information about the prevalence of work-family conflict and job dissatisfaction as well as their associations among female physicians. To explore the prevalence of work-family conflict and its relations to job dissatisfaction among Hungarian physicians. Cross-sectional study with 219 female and 201 male physicians using self-report questionnaires. As hypothesized, female physicians reported significantly higher level of work-family conflict compared to male physicians (3.0 (SD 0.9) vs. 2.6 (SD 0.9); t (df): -3.8 (418); p < 0.001). Furthermore, more female than male physicians experienced work-family conflict often or extremely often [56% vs. 41%, respectively; chi 2 (df) = 9.3 (1); p < 0.01]. Significantly fewer women (55%) than men (66%) reported high levels of job satisfaction [chi 2 (df) = 4.8 (1), p < 0.05]. Similarly, significantly more female physicians (13%) experienced high level of job dissatisfaction compared to men (6%) [chi 2 (df) = 4.7 (1), p < 0.05]. Linear regression analyses showed that work-family conflict predicts job dissatisfaction among female and all physicians (beta = -0.17, 95% CI -0.31 - -0.04 and beta = -0.14, 95% CI -0.22 - -0.04, respectively). These results show that the level and prevalence of work-family conflict experienced by female physicians in Hungary is significantly higher than that among male physicians. Furthermore, these findings suggest that work-family conflict as a stressor may contribute to the development of job dissatisfaction and hence may adversely impact the well-being of female and male physicians and consequently the quality of patient care.

Eating behaviors, nutritional status, and menstrual function in elite female adolescent volleyball players.

Beals, Katherine A

2002-09-01

Nutritional status, eating behaviors and menstrual function was examined in 23 nationally ranked female adolescent volleyball players using a health/weight/ dieting/menstrual history questionnaire, the Eating Disorder Inventory (EDI), and the Body Shape Questionnaire (BSQ). Nutrient and energy intakes (El) and energy expenditure (EE) were determined by 3-d weighed food records and activity logs. Iron (Fe), vitamins C, B12, and Folate status were assessed using serum and whole blood. Mean El (2248 +/- 414 kcal/d) was less than EE (2815 +/- 306 kcal/d). Mean carbohydrate (5.4 +/-1.0g/kg/d) and protein (1.1+/-0.3g/kg/d) intakes were below recommended levels for highly active women. Mean intakes for folate, Fe, Ca, Mg, and Zn were less than the respective RDAs/DRIs and almost 50% of the athletes were consuming less than the RDAs/DRIs for the B-complex vitamins and vitamin C. Three athletes presented with Fe deficiency anemia (Hb <12 mg/dL), while marginal vitamin B12 status (<200 pg/ml) and vitamin C status (<28 mmol/L) were found in 1 and 4 athletes, respectively. Approximately 1/2 of the athletes reported actively "dieting". Mean BSQ and EDI subscales scores were within the normal ranges; yet, elevated scores on these scales were reported by 26% and 35% of athletes, respectively. Past or present amenorrhea was reported by 17% of the athletes and 13% and 48%, reported past or present oligomenorrhea and "irregular" menstrual cycles, respectively. These results indicate that elite adolescent volleyball players are at risk for menstrual dysfunction and have energy and nutrient intakes that place them at risk for nutritional deficiencies and compromised performance.

Acne vulgaris is a very common skin disorder affecting human beings. There is a paucity of report on the role of heavy metals-lead (Pb) and cadmium (Cd)-globally, and trace metals-zinc (Zn) and copper (Cd)-particularly in Nigeria in the development/severity of acne vulgaris. This study is aimed to determine the blood levels of some heavy metals-cadmium and lead-and trace metals-zinc and copper-in acne vulgaris sufferers in a Nigerian population. Venous blood samples were collected from a total number of 90 non-obese female subjects consisting of 30 mild, 30 moderate and 30 severe acne vulgaris sufferers for blood Cd, Pb, Cu and Zn determination. They were age-matched with 60 females without acne vulgaris who served as the control subjects. Acne sufferers had significantly higher blood Cd and Pb (P = 0.0143 and P = 0.0001 respectively) and non-significantly different blood levels of Cu and Zn (P = 0.910 and P = 0.2140 respectively) compared to controls. There were significant progressive increases in blood levels of Cd and Pb (P = 0.0330 and P = 0.0001 respectively) and non-significant differences in the mean blood level of Cu and Zn (P = 0.1821 and P = 0.2728 respectively) from mild to moderate and severe acne vulgaris sufferers. Increases in blood Cd and Pb may play critical roles in the pathogenesis/severity of acne vulgaris, while Cu and Zn seem to play less significant roles in the development of this disorder in this environment.

Background: Plyometric exercises are frequently used to increase posterior rotator cuff and periscapular muscle strength and simulate demands and positional stresses in overhead athletes. The purpose of this study was to provide descriptive data on posterior rotator cuff and scapular muscle activation during upper extremity plyometric exercises in 90° of glenohumeral joint abduction. Hypothesis: Levels of muscular activity in the posterior rotator cuff and scapular stabilizers will be high during plyometric shoulder exercises similar to previously reported electromyographic (EMG) levels of shoulder rehabilitation exercises. Study Design: Descriptive laboratory study. Methods: Twenty healthy subjects were tested using surface EMG during the performance of 2 plyometric shoulder exercises: prone external rotation (PERP) and reverse catch external rotation (RCP) using a handheld medicine ball. Electrode application included the upper and lower trapezius (UT and LT, respectively), serratus anterior (SA), infraspinatus (IN), and the middle and posterior deltoid (MD and PD, respectively) muscles. A 10-second interval of repetitive plyometric exercise (PERP) and 3 repetitions of RCP were sampled. Peak and average normalized EMG data were generated. Results: Normalized peak and average IN activity ranged between 73% and 102% and between 28% and 52% during the plyometric exercises, respectively, with peak and average LT activity measured between 79% and 131% and between 31% and 61%. SA activity ranged between 76% and 86% for peak and between 35% and 37% for average activity. Muscular activity levels in the MD and PD ranged between 49% and 72% and between 12% and 33% for peak and average, respectively. Conclusion: Moderate to high levels of muscular activity were measured in the rotator cuff and scapular stabilizers during these plyometric exercises with the glenohumeral joint abducted 90°.

Available reports on critically ill adults with cystic fibrosis (CF) suggest improving short-term outcomes. However, there is marked heterogeneity in reported findings, with studies mostly based on single-centered data, limiting generalizability. We sought to examine population-level patterns of demand for critical care resources, and the characteristics, resource utilization, and outcomes of ICU-managed adults with CF. We used the Texas Inpatient Public Use Data File to identify ICU admissions with CF aged ≥18 years in Texas between 2004-2013. We examined ICU utilization at population level (using CF Foundation annual reports) and, among ICU admissions, socio-demographic characteristics, burden of comorbidities, organ failure, life-support utilization and hospital disposition. Linear regression and multilevel logistic regression were used to examine temporal trends and predictors of short-term mortality (hospital death and discharge to hospice), respectively. Of 9,579 hospitalizations of adults with CF, 1,249 (13%) were admitted to ICU. The incidence of ICU admission among adults with CF in Texas increased between 2004-2005 and 2012-2013 from 16.7 to 19.2 per 100 person-years (p = 0.0181), with ICU admissions aged ≥30 years accounting for 80.3% of the change. Among ICU admissions the following changes were noted between 2004-2005 and 2012-2013: any organ failure 30.2% vs. 56.3% (p = 0.0004), mechanical ventilation 11.5% vs. 19.2% (p = 0.0216), and hemodialysis 1.0% vs. 8.1% (p = 0.0007). Short-term mortality for the whole cohort and for those with mechanical ventilation was 11.4% and 41.8%, respectively, with corresponding home discharge among survivors 84% and 62.1%, respectively. Key predictors (adjusted odds ratios [aOR (95% CI)]) of short-term mortality included age ≥45 years (2.051 [1.231-3.415]), female gender (1.907 [1.237-2.941]), and mechanical ventilation (7.982 [5.001-12.739]). Adults with CF had high and rising population-level burden of critical illness. Although ICU admissions were increasingly older and sicker, the majority survived hospitalization, with most discharged home, supporting short-term benefits of critical care in the present cohort.

Objective To investigate inequality in disability in Bangladesh. Methods The study used both household level and individual level data from a large nationally representative data set, Bangladesh’s Household Income and Expenditure Survey - 2010. Principal component analysis was used to construct a wealth index based on household assets from household level data. Then, using data from 49,809 individuals aged 5 years and over, chi-square tests and logistic regression were performed to test the association between wealth level and disability. Findings Women and older people are significantly more likely to report having disabilities than men and younger people. For middle and rich families, respectively, there is a 14 percent lower likelihood of reporting disabilities than for poor families. Changes in the probability of having disabilities are linear with increasing wealth. In addition, the study identifies some significant factors affecting disability, namely, age, sex, education, marital status, and place of residence including divisional differences. Conclusion In Bangladesh, worse health among the poor argues for policies prioritizing this group while at the same time giving special attention to women and the elderly. PMID:25075513

A spectrometer to measure nuclear level half-lives has been installed at the on-line isotope separator of the Kyoto University Reactor. This spectrometer consists of a LaBr3 scintillator, a thin plastic scintillator and an HPGe detector. Half-lives are deduced using the β-γ-γ delayed coincidence method. The prompt-time distribution curves measured with the spectrometer give a time resolution (FWHM) of 600 ps for 100-keV γ rays. This resolution means that half-lives down to the subnanosecond range or shorter can be measured. We reported recent measurements of the half-life of {sup 149}Pr and {sup 149}Nd. Some of the more interesting results include themore » first determination of the half-lives of {sup 149}Pr levels at 86.5 and 125.6 keV, which are 4.2(5) ns and 1.0(2) ns, respectively. In addition, the data indicate that the half-life of the 270.8-keV level in {sup 149}Nd is not 5.1(3) ns as reported previously, but 0.42(3) ns.« less

Toward Unified Satellite Climatology of Aerosol Properties. 3. MODIS Versus MISR Versus AERONET

We use the full duration of collocated pixel-level MODIS-Terra and MISR aerosol optical thickness (AOT) retrievals and level 2 cloud-screened quality-assured AERONET measurements to evaluate the likely individual MODIS and MISR retrieval accuracies globally over oceans and land. We show that the use of quality-assured MODIS AOTs as opposed to the use of all MODIS AOTs has little effect on the resulting accuracy. The MODIS and MISR relative standard deviations (RSTDs) with respect to AERONET are remarkably stable over the entire measurement record and reveal nearly identical overall AOT performances of MODIS and MISR over the entire suite of AERONET sites. This result is used to evaluate the likely pixel-level MODIS and MISR performances on the global basis with respect to the (unknown) actual AOTs. For this purpose, we use only fully compatible MISR and MODIS aerosol pixels. We conclude that the likely RSTDs for this subset of MODIS and MISR AOTs are 73% over land and 30% over oceans. The average RSTDs for the combined [AOT(MODIS)+AOT(MISR)]/2 pixel-level product are close to 66% and 27%, respectively, which allows us to recommend this simple blend as a better alternative to the original MODIS and MISR data. These accuracy estimates still do not represent the totality of MISR and quality-assured MODIS pixel-level AOTs since an unaccounted for and potentially significant source of errors is imperfect cloud screening. Furthermore, many collocated pixels for which one of the datasets reports a retrieval, whereas the other one does not may also be problematic.

β-thalassemia is the most common monogenic disorder in human. The (C-->T) polymorphism at -158 upstream region of the γG-globin gene and pharmacological factors such as hydroxyurea have been reported to influence γ-globin gene expression and the severity of clinical symptoms of β-thalassemia. In the present study, 51 β-thalassemia intermediate patients were studied. Xmn1γG polymorphism genotype was determined using Tetra-Primer ARMS-PCR technique. Hemoglobin (Hb) and fetal hemoglobin (HbF) levels were determined by gel electrophoresis. Of 51 patients, 35 (68.6%) patients were heterozygous (CT) and 16 (31.4%) patients were homozygous (CC). Of 30 patients under treatment by hydroxyurea, 20 (66.7%) patients were heterozygous (CT) and 10 (33.3%) patients were homozygous (CC). Our results demonstrated that in the heterozygous (CT) genotype, the Hb (9.58 ± 1.25 gm/dl) and HbF (89.30 ± 21.87) levels were significantly higher in comparison with homozygous (CC) genotype (7.94 ± 1.34 gm/dl and 70.32 ± 40.56, respectively). Furthermore, we observed that after drug usage, the Hb and HbF levels in patients with heterozygous (CT) genotype (0.7 ± 1.26 gm/dl and 5.95 ± 14.8, respectively) raised more in comparison with homozygous (CC) genotype (0.26 ± 1.43 gm/dl and 0.8 ± 1.31, respectively). Hb and HbF levels in the patients carrying T allele are increased significantly, and they also response to hydroxyurea treatment.

First-trimester surgical abortion is a common procedure. Pain control during this procedure is still an unsolved problem. In this randomized, double-blind placebo-controlled study, women presenting for first-trimester surgical abortion received intramuscular phloroglucinol (4 mL) or placebo (normal saline, 4 mL). Visual analog scales (VAS) for pain immediately and 30 min after the procedure and side effects of the drug were recorded. There was no significant difference between groups in the pain level immediately and 30 min after the procedure; 70.7% of the phloroglucinol group (n=58 cases) and 56.9% of the placebo group (n=58 cases ) reported mild pain; 27.6% and 34.5%, respectively, reported moderate pain; and 1.7% and 8.6%, respectively, reported severe pain. Thirty minutes after the procedure, the median pain score was reduced to 1.3 in both groups. Postoperative side effects were reported, but there was no significant difference between groups for nausea or vomiting and blood pressure. The use of this dose of phloroglucinol, during first-trimester abortion by suction evacuation under local anesthesia with lidocaine, did not relieve pain, but caused no side effects.

Self-reported epilepsy may be influenced by culture, knowledge, and beliefs. We screened 6420 residents of the District of Columbia (DC) for epilepsy to investigate whether socio-demographics were associated with whether they reported their diagnosis as epilepsy or as seizure disorder. Lifetime and active prevalence rates were 0.54% and 0.21%, respectively for 'epilepsy' and 1.30% and 0.70%, respectively for 'seizure disorder'. Seizure disorder was reported significantly more often than epilepsy among blacks, females, respondents≥50years, those with lower level education, respondents who lived alone and in low income neighborhoods, and those who resided in DC for at least five years. Clinicians should assure that patients and caregivers understand that epilepsy is synonymous with seizure disorder and other culturally appropriate terms, in order to optimize compliance with treatment, disease management instructions, and utilization of other resources targeted at persons with epilepsy. Furthermore, education and awareness campaigns aimed at improving access-to-care, reducing stigma, and increasing awareness of adverse events, such as SUDEP, should include a more diverse definition of epilepsy in their messages.

Visualized kinematics code for two-body nuclear reactions

NASA Astrophysics Data System (ADS)

Lee, E. J.; Chae, K. Y.

2016-05-01

The one or few nucleon transfer reaction has been a great tool for investigating the single-particle properties of a nucleus. Both stable and exotic beams are utilized to study transfer reactions in normal and inverse kinematics, respectively. Because many energy levels of the heavy recoil from the two-body nuclear reaction can be populated by using a single beam energy, identifying each populated state, which is not often trivial owing to high level-density of the nucleus, is essential. For identification of the energy levels, a visualized kinematics code called VISKIN has been developed by utilizing the Java programming language. The development procedure, usage, and application of the VISKIN is reported.

We report a case of pyroglutamic acidemia probably related to acetaminophen administration. A 16-month boy recovering from hemolytic uremic syndrome abruptly developed unexplained high anion gap metabolic acidosis requiring hemodialysis. Septic shock, lactic acidosis and salicylate intoxication were ruled out. Betahydroxybutyrate and acetoacetate levels were within the normal range. No osmolarity gap or high amino acid levels were found. Urine and blood pyroglutamic acid levels were 392 mmol/mol creatinine (reference range: 9-55) and 9.8 mmol/L (reference range<0.16), respectively. The patient was receiving acetaminophen. We conclude that pyroglutamic acidosis should be considered in patients receiving acetaminophen who abruptly develop high anion gap metabolic acidosis not attributable to more common causes.

Energy levels, radiative rates, oscillator strengths, line strengths, and lifetimes have been calculated for transitions in B-like to F-like Kr ions, Kr XXXIII-XXVIII. For the calculations, the fully relativistic GRASP code has been adopted, and results are reported for all electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1), and magnetic quadrupole (M2) transitions among the lowest 125, 236, 272, 226, and 113 levels of Kr XXXII, Kr XXXI, Kr XXX, Kr XXIX, and Kr XXVIII, respectively, belonging to the n ⩽ 3 configurations. Comparisons are made with earlier available theoretical and experimental results, and some discrepancies have been noted and explained.

2008-07-01

The objective of the present survey was to study self-reported sleep disturbances due to railway noise with respect to nighttime equivalent noise level (L(p,A,eq,night)) and maximum noise level (L(p,A,max)). A sample of 1349 people in and around Oslo in Norway exposed to railway noise was studied in a cross-sectional survey to obtain data on sleep disturbances, sleep problems due to noise, and personal characteristics including noise sensitivity. Individual noise exposure levels were determined outside of the bedroom facade, the most-exposed facade, and inside the respondents' bedrooms. The exposure-response relationships were analyzed by using logistic regression models, controlling for possible modifying factors including the number of noise events (train pass-by frequency). L(p,A,eq,night) and L(p,A,max) were significantly correlated, and the proportion of reported noise-induced sleep problems increased as both L(p,A,eq,night) and L(p,A,max) increased. Noise sensitivity, type of bedroom window, and pass-by frequency were significant factors affecting noise-induced sleep disturbances, in addition to the noise exposure level. Because about half of the study population did not use a bedroom at the most-exposed side of the house, the exposure-response curve obtained by using noise levels for the most-exposed facade underestimated noise-induced sleep disturbance for those who actually have their bedroom at the most-exposed facade.

Background The development of Electronic Health Records (EHRs) forms an integral part of the information strategy for the National Health Service (NHS) in the UK, with the aim of facilitating health information exchange for patient care and secondary use, including research and healthcare planning. Implementing EHR systems requires an understanding of patient expectations for consent mechanisms and consideration of public awareness towards information sharing as might be made possible through integrated EHRs across primary and secondary health providers. Objectives To explore levels of public awareness about EHRs and to examine attitudes towards different consent models with respect to sharing identifiable and de-identified records for healthcare provision, research and planning. Methods A cross-sectional questionnaire survey was administered to adult patients and members of the public in primary and secondary care clinics in West London, UK in 2011. In total, 5331 individuals participated in the survey, and 3157 were included in the final analysis. Results The majority (91%) of respondents expected to be explicitly asked for consent for their identifiable records to be accessed for health provision, research or planning. Half the respondents (49%) did not expect to be asked for consent before their de-identified records were accessed. Compared with White British respondents, those from all other ethnic groups were more likely to anticipate their permission would be obtained before their de-identified records were used. Of the study population, 59% reported already being aware of EHRs before the survey. Older respondents and individuals with complex patterns of interaction with healthcare services were more likely to report prior awareness of EHRs. Individuals self-identifying as belonging to ethnic groups other than White British, and those with lower educational qualifications were less likely to report being aware of EHRs than White British respondents and respondents with degree-level education, respectively. Those who reported being aware of EHRs were less likely to say they expected explicit consent to be sought before use of their de-identified record. Conclusions A large number of patients remain unaware of EHRs, while preference for implicit consent is stronger among those who report previous awareness. Differences in awareness levels and consent expectations between groups with different socio-demographic characteristics suggest that public education and information campaigns should target specific groups to increase public awareness and ensure meaningful informed consent mechanisms.

Recent studies report an association between serum alkaline phosphatase (ALP) levels and inflammation. The present study examined the relationship between ALP and disease activity, bone mineral density (BMD), and radiological damage in axial spondyloarthritis (SpA). A total of 115 patients who fulfilled the ASAS axial SpA criteria were enrolled. Serum ALP, bone-specific ALP (BALP), serum cross-linked telopeptide of type-I collagen (sCTX), and inflammatory markers were measured. Clinical parameters, BMD, grade of sacroiliitis, and the modified Stoke AS Spinal Score (mSASSS) were also assessed. The Ankylosing Spondylitis Disease Activity Score (ASDAS) was also calculated. The associations between serum ALP, disease activity score, BMD, and radiologic damage were evaluated. The mean serum ALP level was 77 ± 26 U/l. Serum ALP levels increased in 14 patients (13%). Serum ALP levels increased along with ASDAS-CRP after adjusting for age and sex (p = 0.004), and were significantly correlated with ASDAS-ESR and ASDAS-CRP (p = 0.001 and p < 0.001, respectively), negatively correlated with BMD in the lumbar spine and femoral neck (p = 0.003 and 0.046, respectively), and positively correlated with sacroiliitis grade and the mSASSS (p < 0.001 and p < 0.002, respectively). BALP and sCTX were not associated with disease activity or BMD. Multivariate analysis showed that serum ALP was independently associated with ASDAS-CRP (p = 0.010). Increased serum ALP levels were associated with high disease activity, low BMD, and higher structural damage scores in SpA patients. Copyright © 2015 Elsevier Inc. All rights reserved.

This study analyzes both the blister fluid (BF) and serum levels of IL-7 and TGF-beta1 in samples from 18 patients affected with bullous pemphigoid (BP). These cytokines clearly present lower concentrations (P<0.001) in BFs than in the sera (1/20 and 1/2, respectively). In contrast, TNF-alpha, IL-10 and IL-4 present increased amounts in BFs that were 12, 12 and 17-fold, respectively. Eighteen sera (and 10 suction BF) from normal individuals were also employed as control. Normal sera presented significantly lower serum IL-7 concentrations than BP, while no significant TGF-beta1 variations were observed between normal and pathologic serum samples. In addition, the serum levels detected in BP patients were significantly correlated with disease intensity (r=0.64, P=0.003, evaluated as the number of blisters/erosions for each patient) as well as with the peripheral B-lymphocyte counts (r=0.80, P<0.001) and antibodies directed against the basement membrane zone (r=0.65, P<0.005). Although a clear explanation of this phenomenon is lacking, the data presented in this report agree with a strong decrease of IL-7 production at the local level (keratinocyte is known to produce IL-7 and the latter is known to be down-regulated by IL-10, and in other models also by TGF-beta1 and IL-4, whose levels are elevated in BP BFs) as opposed to an increased peripheral release of the same modulator. The IL-7 reduction may have a biological relevance in controlling a chronic, progressive disease.

Vibriosis is a leading cause of seafood-associated morbidity and mortality in the United States. Typically associated with consumption of raw or undercooked oysters, vibriosis associated with clam consumption is increasingly being reported. However, little is known about the prevalence of Vibrio spp. in clams. The objective of this study was to compare the levels of Vibrio cholerae, Vibrio vulnificus, and Vibrio parahaemolyticus in oysters and clams harvested concurrently from Long Island Sound (LIS). Most probable number (MPN)-real-time PCR methods were used for enumeration of total V. cholerae, V. vulnificus, V. parahaemolyticus, and pathogenic (tdh(+) and/or trh(+)) V. parahaemolyticus. V. cholerae was detected in 8.8% and 3.3% of oyster (n = 68) and clam (n = 30) samples, with levels up to 1.48 and 0.48 log MPN/g in oysters and clams, respectively. V. vulnificus was detected in 97% and 90% of oyster and clam samples, with median levels of 0.97 and -0.08 log MPN/g, respectively. V. parahaemolyticus was detected in all samples, with median levels of 1.88 and 1.07 log MPN/g for oysters and clams, respectively. The differences between V. vulnificus and total and pathogenic V. parahaemolyticus levels in the two shellfish species were statistically significant (P < 0.001). These data indicate that V. vulnificus and total and pathogenic V. parahaemolyticus are more prevalent and are present at higher levels in oysters than in hard clams. Additionally, the data suggest differences in vibrio populations between shellfish harvested from different growing area waters within LIS. These results can be used to evaluate and refine illness mitigation strategies employed by risk managers and shellfish control authorities. Copyright © 2014, American Society for Microbiology.

Although racial/ethnic, socioeconomic, and neighborhood factors have been linked to asthma, and the association between indoor allergens and asthma is well documented, few studies have examined the relationship between these factors and indoor allergens. We examined the frequency of reported indoor allergens and differences by racial/ethnic, socioeconomic, and neighborhood characteristics among a diverse sample of Los Angeles households. Multilevel logistic regression models were used to analyze the data from 723 households from wave 2 of the Los Angeles Family and Neighborhood Survey. The reported presence of rats, mice, cockroaches, mold, pets, and tobacco smoke were the primary outcomes of interest. Hispanic and Asian households had a nearly threefold increase in the odds of reporting cockroaches compared to non-Hispanic Whites (OR, 2.85; 95 % CI 1.38-5.88 and OR, 2.62; 95 % CI 1.02-6.73, respectively) even after adjusting for socioeconomic factors. Primary caregivers who had obtained a high school degree were significantly less likely to report the presence of mice and cockroaches compared to primary caregivers with less than a high school degree (OR, 0.19; 95 % CI 0.08-0.46 and OR, 0.39; 95 % CI 0.23-0.68, respectively). Primary caregivers with more than a high school degree were also less likely to report the presence of rats, mice, and cockroaches within their households, compared to those with less than a high school degree. Compared to renters, home owners were less likely to report the presence of mice, cockroaches, and mold within their households. At the neighborhood level, households located within neighborhoods of high concentrated poverty (where the average poverty rate is at least 50 %) were more likely to report the presence of mice and cockroaches compared to households in low concentrated poverty neighborhoods (average poverty rate is 10 % or less), after adjusting for individual race/ethnicity and socioeconomic characteristics. Our study found evidence in support of neighborhood-level racial/ethnic and socioeconomic influences on indoor allergen exposure, above and beyond individual factors. Future studies should continue to explore individual and neighborhood-level racial/ethnic and socioeconomic differences in household allergen exposures across diverse contexts.

Increasing the Lifetime of Mobile WSNs via Dynamic Optimization of Sensor Node Communication Activity

2016-01-01

In this paper, a simple and flexible method for increasing the lifetime of fixed or mobile wireless sensor networks is proposed. Based on past residual energy information reported by the sensor nodes, the sink node or another central node dynamically optimizes the communication activity levels of the sensor nodes to save energy without sacrificing the data throughput. The activity levels are defined to represent portions of time or time-frequency slots in a frame, during which the sensor nodes are scheduled to communicate with the sink node to report sensory measurements. Besides node mobility, it is considered that sensors’ batteries may be recharged via a wireless power transmission or equivalent energy harvesting scheme, bringing to the optimization problem an even more dynamic character. We report large increased lifetimes over the non-optimized network and comparable or even larger lifetime improvements with respect to an idealized greedy algorithm that uses both the real-time channel state and the residual energy information.

Timeliness “at a glance”: assessing the turnaround time through the six sigma metrics.

Ialongo, Cristiano; Bernardini, Sergio

2016-01-01

Almost thirty years of systematic analysis have proven the turnaround time to be a fundamental dimension for the clinical laboratory. Several indicators are to date available to assess and report quality with respect to timeliness, but they sometimes lack the communicative immediacy and accuracy. The six sigma is a paradigm developed within the industrial domain for assessing quality and addressing goal and issues. The sigma level computed through the Z-score method is a simple and straightforward tool which delivers quality by a universal dimensionless scale and allows to handle non-normal data. Herein we report our preliminary experience in using the sigma level to assess the change in urgent (STAT) test turnaround time due to the implementation of total automation. We found that the Z-score method is a valuable and easy to use method for assessing and communicating the quality level of laboratory timeliness, providing a good correspondence with the actual change in efficiency which was retrospectively observed.

ACL (anterior cruciate ligament) reconstruction is one of the most commonly performed and studied procedures in modern sports medicine. A multitude of objective and subjective patient outcome measures exists; however, nonstandardized reporting patterns of these metrics may create challenges in objectively analyzing pooled results from different studies. The goal of this study was to document the variability in outcome reporting patterns in high-impact orthopaedic studies of ACL reconstruction. All clinical studies pertaining to ACL reconstruction in four high-impact-factor orthopaedic journals over a five-year period were reviewed. Biomechanical, basic science, and imaging studies were excluded, as were studies with fewer than fifty patients, yielding 119 studies for review. Incorporation of various objective and subjective outcomes was noted for each study. Substantial variability in reporting of both objective and subjective measures was noted in the study cohort. Although a majority of studies reported instrumented laxity findings, there was substantial variability in the type and method of laxity reporting. Most other objective outcomes, including range of motion, strength, and complications, were reported in <50% of all studies. Return to pre-injury level of activity was infrequently reported (24% of studies), as were patient satisfaction and pain assessment following surgery (8% and 13%, respectively). Of the patient-reported outcomes, the International Knee Documentation Committee (IKDC), Lysholm, and Tegner scores were most often reported (71%, 63%, and 42%, respectively). Substantial variability in outcome reporting patterns exists among high-impact studies of ACL reconstruction. Such variability may create challenges in interpreting results and pooling them across different studies. Copyright © 2015 by The Journal of Bone and Joint Surgery, Incorporated.

Glycoprotein 2 (GP2), the pancreatic major zymogen granule membrane glycoprotein, was reported to be elevated in acute pancreatitis in animal models. Enzyme-linked immunosorbent assays (ELISAs) were developed to evaluate human glycoprotein 2 isoform alpha (GP2a) and total GP2 (GP2t) as specific markers for acute pancreatitis in sera of 153 patients with acute pancreatitis, 26 with chronic pancreatitis, 125 with pancreatic neoplasms, 324 with non-pancreatic neoplasms, 109 patients with liver/biliary disease, 67 with gastrointestinal disease, and 101 healthy subjects. GP2a and GP2t levels were correlated with procalcitonin and C-reactive protein in 152 and 146 follow-up samples of acute pancreatitis patients, respectively. The GP2a ELISA revealed a significantly higher assay accuracy in contrast to the GP2t assay (sensitivity ≤3 disease days: 91.7%, specificity: 96.7%, positive likelihood ratio [LR+]: 24.6, LR-: 0.09). GP2a and GP2t levels as well as prevalences were significantly elevated in early acute pancreatitis (≤3 disease days) compared to all control cohorts (p<0.05, respectively). GP2a and GP2t levels were significantly higher in patients with severe acute pancreatitis at admission compared with mild cases (p<0.05, respectively). Odds ratio for GP2a regarding mild vs. severe acute pancreatitis with lethal outcome was 7.8 on admission (p=0.0222). GP2a and GP2t levels were significantly correlated with procalcitonin [Spearman's rank coefficient of correlation (ρ)=0.21, 0.26; p=0.0110, 0.0012; respectively] and C-reactive protein (ρ=0.37, 0.40; p<0.0001; respectively). Serum GP2a is a specific marker of acute pancreatitis and analysis of GP2a can aid in the differential diagnosis of acute upper abdominal pain and prognosis of severe acute pancreatitis.

This small study investigated house dust mite (HDM) allergen levels in cars and their owners' homes in north-east Scotland. Dust samples from twelve households and cars were collected in a standardised manner. The dust samples were extracted and measured for the Dermatophagoides group 2 allergens (Der p 2 and Der f 2) and total soluble protein. Allergen levels at homes tended to be higher than in the cars, but not significantly. However, they significantly correlated with paired car dust samples expressed either per unit weight of dust or soluble protein (rho=0.657; p=0.02 and 0.769; p=0.003, respectively). This points to house-to-car allergen transfer, with the car allergen levels largely reflecting levels in the owner's home. Car HDM allergen levels were lower than those reported in Brazil and the USA. Twenty-five percent of the houses and none of the cars had allergen levels in dust greater than 2000 ng g(-1). This value is often quoted as a threshold for the risk of sensitisation, although a number of studies report increased risk of sensitisation at lower levels. This small study does not allow for characterisation of the distribution of HDM allergen in vehicles in this geographic area, or of the likely levels in other warmer and more humid areas of the UK. Cars and other vehicles are an under-investigated micro-environment for exposure to allergenic material.

This study examines whether partnership-related measures in the second version of the National Public Health Performance Standards (NPHPS) are useful in evaluating level of activity as well as identifying latent constructs that exist among local public health systems (LPHSs). In a sample of 110 LPHSs, descriptive analysis was conducted to determine frequency and percentage of 18 partnership-related NPHPS measures. Principal components factor analysis was conducted to identify unobserved characteristics that promote effective partnerships among LPHSs. Results revealed that 13 of the 18 measures were most frequently reported at the minimal-moderate level (conducted 1%-49% of the time). Coordination of personal health and social services to optimize access (74.6%) was the most frequently reported measure at minimal-moderate levels. Optimal levels (conducted >75% of the time) were reported most frequently in 2 activities: participation in emergency preparedness coalitions and local health departments ensuring service provision by working with state health departments (67% and 61% of respondents, respectively) and the least optimally reported activity was review partnership effectiveness (4% of respondents). Factor analysis revealed categories of partnership-related measures in 4 domains: resources and activities contributing to relationship building, evaluating community leadership activities, research, and state and local linkages to support public health activities. System-oriented public health assessments may have questions that serve as proxy measures to examine levels of interorganizational partnerships. Several measures from the NPHPS were useful in establishing a national baseline of minimal and optimal activity levels as well as identifying factors to enhance the delivery of the 10 essential public health services among organizations and individuals in public health systems.

Benzene is one of the important occupational pollutants. There are some reports about the leukemogenic effects related to low-level exposure to benzene. To study the frequency of micronucleus (MN), nucleoplasmic bridge (NB), and nuclear budding (NBUD) in the peripheral blood lymphocytes of petrochemical workers with low level exposure to benzene. We enrolled 50 workers exposed to low-level benzene and 31 unexposed workers of a petrochemical industry. After exclusion of 3 samples, peripheral blood lymphocytes of the remaining 47 exposed and 31 unexposed workers were analyzed for the frequency of MN, NB, and NBUD by cytochalasin-blocked MN technique. MN was present in 28 (60%) exposed and 18 (58%) unexposed workers. NB was observed in 6 (13%), and 2 (7%) exposed and unexposed workers, respectively; the frequency for NBUD was 20 (43%), and 13 (42%), respectively. No significant difference was found in the observed frequencies of MN, NB, and NBUD in the peripheral blood lymphocytes between the exposed and unexposed group workers. Occupational exposure to low-level benzene does not increase the frequency of MN, NB, and NBUD in the peripheral blood lymphocytes, biomarkers for DNA damage.

The effects of workplace respect and violence on nurses' job satisfaction in Ghana: a cross-sectional survey.

Studies have established the negative effects of workplace disrespect and violence on the personal and professional well-being of nurses. In spite of this, only a few have directly investigated the effects of these issues on nurses' job satisfaction. In Africa, research on nurses' job satisfaction continues to focus largely on economic factors. The aim of this paper was, therefore, to investigate the impact of the non-economic factors of workplace violence and respect on the job satisfaction levels of nurses in Ghana. The study employed a cross-sectional questionnaire survey. It involved 592 qualified practising nurses working in public hospitals in Ghana. Data were collected between September 2013 and April 2014. The results showed that, overall, nurses were neither satisfied nor dissatisfied with their jobs (M = 3.19, SD = .54). More than half (52.7%) of the participants had been abused verbally, and 12% had been sexually harassed in the 12 months prior to the study. The majority of nurses, however, believed they were respected at the workplace (M = 3.77, SD = .70, Mode = 4). Multiple regression analyses showed that verbal abuse and perceived respect were statistically significant predictors of nurses' job satisfaction. Nurses who experienced verbal abuse and low level of respect were more likely to report low job satisfaction scores. It is concluded that non-financial strategies such as safe work environments which are devoid of workplace violence may enhance nurses' job satisfaction levels. A policy of "zero tolerance" for violence and low tolerance for disrespect could be put in place to protect nurses and healthcare professionals in general.

Human exposure to trace levels of pesticide residues present in food of plant origin is inevitable as long as pesticides continue to be applied in agriculture. Since Maximum Residue Levels (MRL) are not toxicological endpoint values, their violation is not by default equivalent to health risk for consumers. However, its essential to provide a health- based risk assessment for each case of MRL non-compliance reported during monitoring and official control of foodstuffs. To assess the potential short-term risk associated with consumption of food products of plant origin containing pesticide residues above MRL values based on notifications forwarded by the National Contact Point for RASFF in Poland during 2011-2015. 115 notifications including 127 analytical results non-compliant with respective MRL values were forwarded to provide risk assessment. An internationally accepted deterministic approach based on conservative model assumptions for short-term exposure assessment was applied. The risk was characterized by comparing an estimated dietary intake with respective acute reference dose (ARfD). Black currant, tea, lettuce, Chinese cabbage and carrot were among the most frequently notified products in years 2011-2015. Among pesticides exceeding respective MRL values, over 90% belonged to fungicides and insecticides/acaricides such as acetamiprid, chlorpyrifos, dimethoate, imidacloprid, dithiocarbamates and procymidone. For 15 and 6 results noncompliant with respective MRL value, a predicted short-term intake exceeded ARfD for children and adults, respectively. Residue levels that could potentially pose a health threat are found incidentally. The science-based and transparent risk assessment process with regard to the data, methods and assumptions that are applied is essential to risk management authorities. risk assessment, pesticide residues, MRL, dietary intake, RASFF, food safety.

We report upper limits on the cross sections for the Ξ-p elastic and conversion processes based on the observation of one Ξ-p elastic scattering events with an invisible Λ decay. The cross section for the Ξ-p elastic scattering is, for simplicity, assumming an isotropic angular distribution, found to be 40 mb at 90% confidence level, whereas that for the Ξ-p → ΛΛ reaction is 11 mb at 90% confidence level. While the results on the elastic cross section give no stringent constraint on theoretical estimates, the upper limit on the conversion process suggests that the estimate of the RGM-F model prediction could be ruled out. We also report some preliminary results on the obervation of the stopped-Ξ- hyperon-nucleus interaction with respect to hypernuclear production and existence of doubly-strange H-dibaryon.

Pituitary gigantism, a condition of endogenous growth hormone (GH) hypersecretion prior to epiphyseal closure, is a rare condition. In the adult condition of GH excess, acromegaly, the occurrence of type 2 diabetes mellitus (T2DM) and diabetic ketoacidosis (DKA) have been reported, with resolution following normalization of GH levels. We report the case of a 16-year-old male with pituitary gigantism due to a large invasive suprasellar adenoma who presented with T2DM and DKA. Despite surgical de-bulking, radiotherapy and medical treatment with cabergoline and pegvisomant, GH and insulin-like growth factor-I (IGF-I) levels remained elevated. However, the T2DM and recurrent DKA were successfully managed with metformin and low-dose glargine insulin, respectively. We review the pathophysiology of T2DM and DKA in growth hormone excess and available treatment options.

This study used Ecological Momentary Assessment (EMA) in mother-child dyads to examine the day-level associations of stress and eating. Mothers and their 8- to 12-year-old children ( N = 167 dyads) completed between three (weekday) and eight (weekend) EMA survey prompts per day at random nonschool times across 8 days. EMA measured perceived stress, and past 2-hour healthy (i.e., fruit and vegetables) and unhealthy (e.g., pastries/sweets, soda/energy drinks) eating. Children reported more healthy and unhealthy eating on days when their mothers also engaged in more healthy and unhealthy eating, respectively. On days when mothers' perceived stress was greater than usual, they reported more healthy eating. Eating behaviors were coupled between mothers and children at the day level. Mothers' stress was related to their own eating but not to children's eating.

Psychobiological convergence-the alignment of task-related changes in children's self-reported and physiological indices of reactivity-has recently emerged as a powerful correlate of children's attachment representations, but has not been explored for its association with children's self-reported attachment, with parents' attachment, or with respect to cardiovascular reactivity. The present study found that, within a diverse community sample of mothers and school-aged children (N = 104, M age  = 10.31), the positive link between cardiovascular (respiratory sinus arrhythmia [RSA]) and subjective reactivity to a stressor was only significant among children with high levels of security and children of mothers with low levels of attachment avoidance and anxiety. The convergence of children's subjective and physiological experience is discussed as a key developmental competence that may lay the groundwork for effective coping. © 2018 Wiley Periodicals, Inc.

This report mainly summarizes the results of our study in which the physiological effects of laughter--as a positive emotional expression--were analyzed with respect to gene expression changes to demonstrate the hypothesis that the mind and genes mutually influence each other. We observed that laughter suppressed 2-h postprandial blood glucose level increase in patients with type 2 diabetes and analyzed gene expression changes. Some genes showed specific changes in their expression. In addition, we revealed that laughter decreased the levels of prorenin in blood; prorenin is involved in the onset of diabetic complications. Further, laughter normalized the expression of the prorenin receptor gene on peripheral blood leukocytes, which had been reduced in diabetic patients; this demonstrated that the inhibitory effects of laughter on the onset/deterioration of diabetic complications at the gene-expression level. In a subsequent study, we demonstrated the effects of laughter by discriminating 14 genes, related to natural killer (NK) cell activity, to exhibit continuous increases in expression as a result of laughter. Our results supported NK cell-mediated improvement in glucose tolerance at the gene-expression level. In this report, we also review other previous studies on laughter.

The effect of letter string length and report condition on letter recognition accuracy.

PubMed

Raghunandan, Avesh; Karmazinaite, Berta; Rossow, Andrea S

Letter sequence recognition accuracy has been postulated to be limited primarily by low-level visual factors. The influence of high level factors such as visual memory (load and decay) has been largely overlooked. This study provides insight into the role of these factors by investigating the interaction between letter sequence recognition accuracy, letter string length and report condition. Letter sequence recognition accuracy for trigrams and pentagrams were measured in 10 adult subjects for two report conditions. In the complete report condition subjects reported all 3 or all 5 letters comprising trigrams and pentagrams, respectively. In the partial report condition, subjects reported only a single letter in the trigram or pentagram. Letters were presented for 100ms and rendered in high contrast, using black lowercase Courier font that subtended 0.4° at the fixation distance of 0.57m. Letter sequence recognition accuracy was consistently higher for trigrams compared to pentagrams especially for letter positions away from fixation. While partial report increased recognition accuracy in both string length conditions, the effect was larger for pentagrams, and most evident for the final letter positions within trigrams and pentagrams. The effect of partial report on recognition accuracy for the final letter positions increased as eccentricity increased away from fixation, and was independent of the inner/outer position of a letter. Higher-level visual memory functions (memory load and decay) play a role in letter sequence recognition accuracy. There is also suggestion of additional delays imposed on memory encoding by crowded letter elements. Copyright © 2016 Spanish General Council of Optometry. Published by Elsevier España, S.L.U.

The objective of this case report is to describe the laparoscopic insertion of an artificial periprostatic urinary sphincter. We report the case of a paraplegic patient in whom an artificial urinary sphincter was inserted in a periprostatic position by way of laparoscopy to treat stress urinary incontinence. In addition to laparoscopy being minimally invasive, its advantages include the excellent quality of retroprostatic dissection and the perfect visualization it gives at the level of cuff positioning with respect to the anatomic landmarks. It is more appropriate to be able to cleave the interprostatorectal space to ensure passage of the cuff under perfectly safe conditions.

Retrospective analysis of clinical records. To assess and compare the improvement in sagittal balance after one- or two-level closing wedge osteotomy for correcting thoracolumbar kyphosis secondary to ankylosing spondylitis (AS). Closing wedge osteotomy represents a common approach to correct kyphosis in AS. Although several reports have described the outcomes of one- or two-level closing wedge osteotomy in terms of sagittal parameters, data comparing the outcomes of these procedures are scarce. Between January 2010 and December 2014, 22 patients with AS underwent closing wedge osteotomy (one-level, 12 patients; two-level, 10 patients) for correcting thoracolumbar kyphosis (mean follow-up, 24.8 months; range, 12-60 months). Preoperative and postoperative chin-brow vertical angle, and the sagittal parameters of the vertebral osteotomy segment were documented and compared. Perioperative and postoperative complications were also recorded. The chin-brow vertical angle improved significantly, from 55.0° ± 27.3° to 4.7° ± 4.9° and from 38.2° ± 14.9° to 3.2° ± 5.4° in the one-level and two-level groups, respectively. The total correction (thoracic kyphosis and lumbar lordosis) was 32.8° ± 18.2° and 53.7° ± 9.4° in the one-level and two-level groups, respectively. No death, complete paralysis, or vascular complications occurred during the procedure, but cerebrospinal fluid leak was noted in one and two patients from the one-level and two-level groups, respectively. A distal pedicle screw adjacent to the osteotomy segment became loose during surgery in one patient (one-level group). Postoperatively, no transient neurological deficit, infection, delay union, or loosening or breaking of the internal fixation devices was observed. Osteotomy site fusion was achieved in all patients, and the Oswestry Disability Index scores improved significantly. Closing wedge osteotomy is effective and safe for correcting thoracolumbar kyphosis in patients with AS. Significant correction and improvement in all sagittal parameters were noted in both groups, but two-level closing wedge osteotomy provided better correction. 3.

Prostate cancer is the most common male cancer. Insufficient knowledge of PCa among men causes its low detection. Lack of essential actions in health education and widely understood prophylaxis, the need of the latter are maybe responsible for the increasing mortality rate. According to our assumption, educating men increase their awareness on the need of screening tests and results in increasing reporting to physical examinations. This in turn allows for an early detection of the disease. A research was conducted between the years 2003-2009 on the knowledge of PCa among 260 men. They were divided into two groups. Group A - 63 patients treated for carcinoma of prostate and group B - 197 men reporting spontaneously to screening tests. In order to check the adopted hypothesis, we prepared an educational material and test of knowledge - test with a questionnaire. Knowledge was evaluated before (test I) and after the education process (test II). Until 2009, we were monitoring the number of patients from group B reporting to screening tests and their knowledge was once again checked (test III). Two subgroups C and D were created from group B - 117 healthy men and 80 with diagnosed diseases respectively (70 with benign prostatic hyperplasia, 7 with prostatitis, and 3 with carcinoma of prostate). Patients with prostatitis and PCa and 3 patients from group C not reporting to the tests were excluded from further monitoring. Maths statistics with the use of SPSS 12.0 PL program and Statistica 6.0 constituted the base for working out the results. We observed a higher knowledge about carcinoma of prostate in group A than in group B (p <0.0001) and it increased after 5 years in group D (p <0.0001) in comparison to group C. Patients aged >40 from groups C and D were interested in health care (p<0.01) as much as patients aged 40-49, 50-59 and 60-69. In men >70 a lower level of motivation was observed. The interest was proportional to the level of education, and this was differentiating in an analogical way the motivation to extend knowledge about prostate cancer (p<0.001). The place of living was determining the level of motivation for broadening knowledge - in bigger towns in a greater extent (p <0.01). The frequency of reporting to screening tests during a period of 5 years was comparable in groups C and D, regardless of knowledge tests' results. Health risk awareness following the education process was motivating men to undergo screening tests (p <0.05). This confirms our own research hypothesis. Regardless of the age bracket, the obtained result of knowledge test II was higher than test I and the result of test III was lower than test II, respectively: p <0.01; p <0.08; p <0.01; p <0.001. The level of knowledge test III among all examined patients was higher in comparison to test I - p <0.01; p <0.001; p <0.001 respectively. White-collar workers obtained in test I a result higher than blue-collar workers, unemployed or retired people p <0.001 and p <0.01 respectively. Unemployed and retired people obtained more scores than blue-collar workers (p <0.05). Both in professional workers and retired people test III was higher than test I - p <0.001 and p <0.001 respectively. In 7 examined men prostate cancer was diagnosed; in group B in 3 in an advanced state, and during 5 years in group C - in 4 men at an early development stage. In the examined men, we observed an almost complete lack of knowledge about carcinoma of prostate, hence they did not report to screening tests.The education process influenced the level of knowledge about carcinoma of prostate. The examined men >40, inhabitants of bigger towns with higher education, less with secondary education and still less with elementary education showed interest in improving their health knowledge.Due to increasing knowledge about carcinoma of prostate, patients were undertaking systematic tests - on average once a year. It confirmed the fact that education on prostate cancer influences its early detection.Education on carcinoma of prostate on a large scale may lead to decreasing morbidity and mortality rates.

Equity and the utilization of health services: report of an eight-province survey in China.

This paper investigates equity with respect to one component of welfare in China--the provision and use of health services. Based upon a large-scale survey of almost 16,000 individuals in eight provinces in China, we examine a sub-sample of working-age adults who have identified themselves as injured or ill during the four weeks prior to being interviewed. We found that, beyond the level of severity of the reported condition, very few individual-level factors are related to the use of services when ill or injured. Only gender (female) and employment in state-run enterprises are associated with higher patterns of use. These results suggest that China has achieved a very wide distribution of clinics and other services at the local level, and that they are widely used by those who identify need for them. It is rare to be over half an hour away by bike from some form of care and the majority of care appears to be reasonably inexpensive. This broad availability of services contrasts with recent reports from China stressing declining accessibility, and paints a picture of relatively equal access to health care.

Background: Obesity, particularly visceral and ectopic adiposity, increases the risk of type 2 diabetes. Objective: The aim of this study was to determine if restriction of dietary carbohydrate is beneficial for body composition and metabolic health. Methods: Two studies were conducted. In the first, 69 overweight/obese men and women, 53% of whom were European American (EA) and 47% of whom were African American (AA), were provided with 1 of 2 diets (lower-fat diet: 55%, 18%, and 27% of energy from carbohydrate, protein, and fat, respectively; lower-carbohydrate diet: 43%, 18%, and 39%, respectively) for 8 wk at a eucaloric level and 8 wk at a hypocaloric level. In the second study, 30 women with polycystic ovary syndrome (PCOS) were provided with 2 diets (lower-fat diet: 55%, 18%, and 27% of energy from carbohydrate, protein, and fat, respectively; lower-carbohydrate diet: 41%, 19%, and 40%, respectively) at a eucaloric level for 8 wk in a random-order crossover design. Results: As previously reported, among overweight/obese adults, after the eucaloric phase, participants who consumed the lower-carbohydrate vs. the lower-fat diet lost more intra-abdominal adipose tissue (IAAT) (11 ± 3% vs. 1 ± 3%; P < 0.05). After weight loss, participants who consumed the lower-carbohydrate diet had 4.4% less total fat mass. Original to this report, across the entire 16-wk study, AAs lost more fat mass with a lower-carbohydrate diet (6.2 vs. 2.9 kg; P < 0.01), whereas EAs showed no difference between diets. As previously reported, among women with PCOS, the lower-carbohydrate arm showed decreased fasting insulin (−2.8 μIU/mL; P < 0.001) and fasting glucose (−4.7 mg/dL; P < 0.01) and increased insulin sensitivity (1.06 arbitrary units; P < 0.05) and “dynamic” β-cell response (96.1 · 109; P < 0.001). In the lower-carbohydrate arm, women lost both IAAT (−4.8 cm2; P < 0.01) and intermuscular fat (−1.2 cm2; P < 0.01). In the lower-fat arm, women lost lean mass (−0.6 kg; P < 0.05). Original to this report, after the lower-carbohydrate arm, the change in IAAT was positively associated with the change in tumor necrosis factor α (P < 0.05). Conclusion: A modest reduction in dietary carbohydrate has beneficial effects on body composition, fat distribution, and glucose metabolism. This trial was registered at clinicaltrials.gov as NCT00726908 and NCT01028989. PMID:25527677

Although various effective interventions are available to help individuals quit smoking, the effect of educational levels on cessation rates has rarely been studied, and of the few intervention studies on this topic, the results have been conflicting. From October 2008 to August 2013, a partly retrospective non-randomised study was conducted in a smoking cessation clinic of a large general hospital in Beijing, China. In total, 547 Chinese smokers who sought treatment were divided into two groups: a face-to-face counselling group (FC, n=149) and an FC group subjected to four telephone follow-up sessions (FCF, n=398). We evaluated self-reported cessation rates by day 7 and after 6 and 12 months and stratified the two groups by education levels. The 7-day and 6-month and 12-month continuous cessation rates of smokers of low education levels in the FC group at the time of the 12-month follow-up were 12.5%, 7.1% and 7.1%, respectively, which were lower than those of the highly educated smokers (16.1%, 12.9% and 9.7%, respectively). The results were opposite for the FCF group. The corresponding results for the highly educated smokers of the FCF group were 25.0%, 17.2% and 10.3%, respectively, which were lower than those for the smokers of low education levels (28.3%, 22.9% and 18.1%, respectively). However, significant differences were observed only among the FCF group participants who had experienced 12 months of continuous abstinence, and the crude OR for these individuals was recorded at 0.52 (0.29 to 0.93), p=0.03. A stepwise logistic regression showed that education levels may play a role in various intervention methods. Being married and higher Fagerström test scores were also predictors of cessation tendencies. Education levels may affect the benefits of booster counselling sessions on smoking cessation among Chinese smokers. Published by the BMJ Publishing Group Limited.

Acrylamide formation in sweetpotato French fries (SPFF) is likely a potential health concern as there is an increasing demand for good-quality fries from carotene-rich sweetpotatoes (SP). This is the first report on acrylamide formation in SPFF as affected by processing methods. Acrylamide levels in SPFF from untreated SP strips fried at 165 °C for 2, 3, and 5 min were 124.9, 255.5, and 452.0 ng/g fresh weight, which were reduced by about 7 times to 16.3, 36.9, and 58.3 ng/g, respectively, when the strips were subjected to processing that included water blanching and soaking in 0.5% sodium acid pyrophosphate before frying. An additional step of strip soaking in 0.4% calcium chloride solution before par-frying increased the calcium content from 0.2 to 0.8 mg/g and decreased the acrylamide levels to 6.3, 17.6, and 35.4 ng/g, respectively. SPFF with acrylamide level of <100 ng/g or several times lower than that of white potato French fries can be obtained by integrating processing treatments commonly used in the food industry.

Macrophage activation syndrome (MAS) is the secondary hemophagocytic lymphohistiocytosis associated with rheumatic diseases. Recently, the different cytokine profiles between systemic juvenile idiopathic arthritis (sJIA)-associated MAS (sJIA-MAS) and juvenile systemic lupus erythematosus (JSLE)-associated MAS (JSLE-MAS) were reported. However, there is little information about juvenile dermatomyositis (JDM)-associated MAS (JDM-MAS). A 4-year-old girl with JDM was hospitalized because of fever, erythema, hepatosplenomegaly, cytopenia, liver dysfunction and coagulopathy. Bone marrow aspiration revealed appreciable numbers of activated and hemophagocytosing macrophages. She was diagnosed as having JDM-MAS complicated with interstitial pneumonia (IP) based on the findings of the elevation of serum Krebs von den Lungen-6 (KL-6) levels and chest computed tomography findings. We analyzed circulating levels of interleukin (IL)-2,4,6,10,18, tumor necrosis factor-α and interferon-γ in the patient. Hypercytokinemia occurred at the diagnosis of MAS and IP, showing with the prominent elevations of IL-6 and IL-18 levels. The cytokine profiles were distinct from those reported in patients with sJIA-MAS or JSLE-MAS. High-dose corticosteroid and cyclosporine therapy led to a drastic improvement of MAS with decreased IL-6 levels. Subsequent cyclophosphamide therapy successfully controlled IP, paralleled with the declining pattern of IL-18 and KL-6 levels. This is the first report to describe a successful treatment and the cytokine profile of JDM-MAS and IP. Serum IL-6 and IL-18 levels may be useful for predicting the disease activity of JDM-MAS and IP, respectively.

To estimate the proportion of diabetes, obesity and non-optimum blood pressure levels in a group of employees of the University of Puerto Rico Medical Sciences Campus that participated in a diabetes health fair at the "Centro de Diabetes para Puerto Rico". A total of 113 participants of the diabetes health fair completed a questionnaire to obtain demographic characteristics and the frequency of self-reported diabetes. The nursing staff examined the participants in order to obtain the following clinical characteristics: body mass index, blood pressure and blood glucose levels. The proportion of self-reported diabetes, obesity (> or = 30 kg/m2) and non-optimum blood pressure levels (systolic > or = 20 mm/Hg or diastolic > or = 80 mm/Hg) were 15.4% (95% CI: 8.5% - 25.7%), 80.0% (95% CI: 70.8%-86.9%) and 70.5% (95% CI: 61.1%-78.6%), respectively. Although it was not statistically significant, diabetes was higher among females (15.4%) compared to males (12.0%). All participants with self-reported diabetes were overweight or obese, and 91.7% showed non-optimum blood pressure levels. A significant positive correlation (p < 0.001) was observed between blood pressure levels and body mass index (r = 0.3). The percentage of persons with diabetes, obesity, and non-optimum blood pressure levels in this sample of Medical Sciences Campus employees underscores the need for confirming these results in a larger study and developing strategies focused on reducing health risks in this population.

DIALOG assessed the prevalence and predictors of hypoglycaemia in patients with type 1 (T1DM) or insulin-treated type 2 diabetes mellitus (T2DM) in a real-life setting. In this observational study, insulin-treated patients (n=3048) completed prospective daily questionnaires reporting the frequency and consequences of severe/confirmed non-severe hypoglycaemia over 30 days. Patients (n=3743) also retrospectively reported severe hypoglycaemia over the preceding year. In this prospective survey, 85.3% and 43.6% of patients with T1DM and T2DM, respectively, reported experiencing at least one confirmed hypoglycaemic event over 30 days, while 13.4% and 6.4%, respectively, reported at least one severe event. Hypoglycaemia frequency increased with longer duration of diabetes and insulin therapy. Strongly predictive factors for hypoglycaemia were previous hypoglycaemia, >2 injections/day, BMI<30kg/m(2) and duration of insulin therapy>10 years. HbA1c level was not predictive of hypoglycaemia in either T1DM or T2DM. The confirmed hypoglycaemia rate was increased in the lowest compared with the highest tertile of HbA1c in T1DM, but not T2DM. At the time of enrolment, physicians reported severe hypoglycaemia in 23.6% and 11.9% of T1DM and T2DM patients, respectively, during the preceding year; the retrospective survey yielded frequencies of 31.5% and 21.7%, respectively. Also, severe hypoglycaemia led to medical complications in 10.7% and 7.8% of events in T1DM and T2DM patients, respectively, over 30 days. Using a unique combined prospective and retrospective approach, the DIALOG study found a relatively high frequency of hypoglycaemia among insulin-treated patients. These findings emphasize the importance of a patient-centred approach for managing diabetes in which hypoglycaemia risk evaluation is critical. ClinicalTrials.gov: NCT01628341.

Iraq and Afghanistan War veterans were grouped by level of posttraumatic stress disorder (PTSD) symptomatology and compared on self-report measures of trait anger, hostility, and aggression. Veterans who screened positive for PTSD reported significantly greater anger and hostility than those in the subthreshold-PTSD and non-PTSD groups. Veterans in the subthreshold-PTSD group reported significantly greater anger and hostility than those in the non-PTSD group. The PTSD and subthreshold-PTSD groups did not differ with respect to aggression, though both groups were significantly more likely to have endorsed aggression than the non-PTSD group. These findings suggest that providers should screen for anger and aggression among Iraq and Afghanistan War veterans who exhibit symptoms of PTSD and incorporate relevant anger treatments into early intervention strategies.

Objectives To explore whether daytime napping and sleep duration are linked to serum C reactive protein (CRP), a pro-inflammatory marker, in an older aged British population. Design Cross-sectional study. Setting European Prospective Investigation into Cancer and Nutrition (EPIC)-Norfolk study. Participants A total of 5018 men and women aged 48–92 years reported their sleep habits and had serum CRP levels measured. Outcome and measures CRP was measured (mg/L) during 2006–2011 in fresh blood samples using high-sensitivity methods. Participants reported napping habits during 2002–2004, and reported sleep quantity during 2006–2007. Multivariable linear regression models were used to examine the association between napping and log-transformed CRP, and geometric mean CRP levels were calculated. Results After adjustment for age and sex, those who reported napping had 10% higher CRP levels compared with those not napping. The association was attenuated but remained borderline significant (β=0.05 (95% CI 0.00 to 0.10)) after further adjustment for social class, education, marital status, body mass index, physical activity, smoking, alcohol intake, self-reported health, pre-existing diseases, systolic blood pressure, hypnotic drug use, depression and in women-only hormone replacement therapy use. The geometric means (95% CI) of CRP levels were 2.38 (2.29 to 2.47) mg/L and 2.26 (2.21 to 2.32) mg/L for those who reported napping and no napping, respectively. A U-shaped association was observed between time spent in bed at night and CRP levels, and nighttime sleep duration was not associated with serum CRP levels. The association between napping and CRP was stronger for older participants, and among extremes of time spent in bed at night. Conclusions Daytime napping was associated with increased CRP levels in an older aged British population. Further studies are needed to determine whether daytime napping is a cause for systemic inflammation, or if it is a symptom or consequence of underlying health problems. PMID:25387759

Contraceptive decision making occurs in the context of relationships. Although many individual-level characteristics have been linked to youths' contraceptive use, less is known about associations between contraceptive use and relationship-level characteristics. Data from the 2001-2002 romantic pair subsample of the National Longitudinal Study of Adolescent Health were used to describe characteristics of 322 dating relationships and 406 cohabiting relationships among young adults aged at least 18 years. Logistic regression was employed to assess associations between these characteristics and hormonal or long-acting contraceptive use and condom use. Data from both partners allowed discordance in reports between partners in some measures to be examined. Cohabiting couples were less likely than dating couples to have used condoms (19% vs. 37%) and hormonal or long-acting methods (40% vs. 57%) at last sex. In dating relationships, couples reporting discordant levels of intimacy and couples in which neither partner reported a high level of intimacy had greater odds of condom use than couples in which both partners reported high intimacy (odds ratios, 4.5 and 3.3, respectively); mistrust and male problem drinking were negatively associated with condom use (0.3 for each). For cohabiting couples, frequency of sex was negatively associated with condom use and hormonal method use (0.8 for each). At least for dating couples, contraceptive use is linked to multiple dimensions of relationships, particularly measures reflecting relationship quality-both positive and negative.

Objectives We examined the level of agreement between biomedical and self-reported measurements of hypertension and diabetes in a Chinese national community sample, and explored associations of the agreement and possible contextual effects among provinces and geographic regions in China. Design Secondary analysis of a cohort sample. Setting and participants Community samples were drawn from the national baseline survey of the China Health and Retirement Longitudinal Study (CHARLS, 2011–2012) through multistage probability sampling, which included households with members 45 years of age or above with a total sample size of 17 708 individuals. Outcome measures Sensitivity, specificity and κ were used as measurements of agreements or validity; variance of validity measures among provinces and communities was estimated using random-effects models. Results Self-reports for hypertension and diabetes showed high specificity (96.3% and 98.3%, respectively) but low sensitivity (56.3% and 61.5%, respectively). Agreement between self-reported data and biomedical measurements was moderate for both hypertension (κ 0.57) and diabetes (κ 0.65), with respondents who were older, of higher socioeconomic status, better educated and who had hospital admissions in the past 12 months showing stronger agreements than their counterparts. Large and significant variations in the sensitivity among provinces for hypertension, and among communities for both hypertension and diabetes, could neither be attributed to the effects of respondents’ characteristics nor to the contextual effects of city–village differences. Conclusions As a considerable number of people in the overall sample were unaware of their conditions, self-reports will lead to an underestimation of the prevalence of hypertension and diabetes. However, in more developed communities or provinces, self-reported data can be a reliable estimate of the prevalence of the two conditions. Further investigations of contextual effects at provincial and community levels could highlight public health strategies to improve awareness of the two conditions. PMID:26729390

To compare self-reported 12-month continuation of oral contraceptive pills (OCPs), patch, and ring versus continuation by pharmacy claims data. Women in the Contraceptive CHOICE Project who chose OCPs, the patch, or the ring as their initial method were included. Continuation was assessed by periodic telephone survey and by obtaining prescription claims data. Continuation was defined as no gap of more than 30 days. Kaplan-Meier survival functions were used to estimate continuation rates and cumulative unintended pregnancy rates. Kappa statistic assessed the level of agreement between self-report and claims data. We analyzed 1510 women who initiated use by 3 months and provided information on discontinuation. Of OCP users, 59% continued their method at 12 months by self-report versus 38% by pharmacy claims. Patch and ring users had self-reported/pharmacy continuation of 45%/28% and 57%/37%, respectively. Kappa coefficients and their 95% confidence intervals between the two measurements were 0.46 (0.40, 0.52), 0.54 (0.39, 0.68), and 0.54 (0.47, 0.61) for OCP, patch, and ring, respectively. Among women who self-reported continuation, unintended pregnancy rates were 0.4% in those who continued by pharmacy claims versus 4.9% in those who discontinued according to claims data. Contraceptive continuation rates differ by self-report versus pharmacy claims with women overestimating their continuation by self-report. This article directly compares contraception continuation rates by self-report and by pharmacy claims data. The study suggests that previously reported continuation rates from survey data overestimate specific method use. Copyright © 2015 Elsevier Inc. All rights reserved.

Several studies have found that metabolic syndrome and uric acid level are related to abnormal liver function test results. The aim of this study was to explore the associations of risk factors [including blood pressure, blood sugar, total cholesterol, triglyceride, uric acid, waist circumference and body mass index (BMI) measurements] with abnormal liver function in the Taiwanese population.In total, 11,411 Taiwanese adults were enrolled in this study. Blood pressure was assessed according to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure criteria, fasting blood sugar level according to the Bureau of Health Promotion, Department of Health, R.O.C., criteria, total cholesterol and triglyceride levels according to the Third Report of the National Cholesterol Education Program Adult Treatment Panel III criteria, BMI according to the Asia-Pacific criteria, and waist circumference according to the Revised Diagnostic Criteria of Metabolic Syndrome in Taiwan. The prevalence of a past history of hypertension and diabetes mellitus was 17.7% and 6.5%, respectively, and the rates of abnormal measurements of blood pressure, BMI, waist circumference, fasting blood sugar, triglyceride, total cholesterol, uric acid (male/female), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were 76.2%, 67.6%, 40.0%, 28.6%, 30.6%, 57.3%, 37.9%/21.9%, 14.6% and 21.3%, respectively. Multivariate analysis showed that waist circumference, BMI, serum uric acid, blood sugar, and triglyceride levels were related to abnormal AST and ALT (p<0.05), but the odds ratio for waist circumference was larger than that for BMI. In conclusion, waist circumference, BMI, serum uric acid, blood sugar, and triglyceride levels are important risk factors for abnormal AST and ALT readings in Taiwanese adults. Waist circumference might be a better indicator of risk of abnormal liver function than BMI. Copyright © 2012. Published by Elsevier B.V.

To optimize the preparation factors for argan oil microcapsule using complex coacervation of chitosan cross-linked with gelatin based on hybrid-level orthogonal array design via SPSS modeling. Eight relatively significant factors were firstly investigated and selected as calculative factors for the orthogonal array design from the total of ten factors effecting the preparation of argan oil microcapsule by utilizing the single factor variable method. The modeling of hybrid-level orthogonal array design was built in these eight factors with the relevant levels (9, 9, 9, 9, 7, 6, 2 and 2 respectively). The preparation factors for argan oil microcapsule were investigated and optimized according to the results of hybrid-level orthogonal array design. The priorities order and relevant optimum levels of preparation factors standard to base on the percentage of microcapsule with the diameter of 30~40 μm via SPSS. Experimental data showed that the optimum factors were controlling the chitosan/gelatin ratio, the systemic concentration and the core/shell ratio at 1:2, 1.5% and 1:7 respectively, presetting complex coacervation pH at 6.4, setting cross-linking time and complex coacervation at 75 min and 30 min, using the glucose-delta lactone as the type of cross-linking agent, and selecting chitosan with the molecular weight of 2000～3000.

Individualized and institutionalized residential place-based discrimination and self-rated health: a cross-sectional study of the working-age general population in Osaka city, Japan

PubMed Central

2014-01-01

Background Several studies have reported that individualized residential place-based discrimination (PBD) affects residents’ health. However, studies exploring the association between institutionalized PBD and health are scarce, especially in Asian countries including Japan. Methods A cross-sectional study was conducted with random two-stage sampling of 6191 adults aged 25–64 years in 100 census tracts across Osaka city in 2011. Of 3244 respondents (response rate 52.4%), 2963 were analyzed using multilevel logistic regression to examine the association of both individualized and institutionalized PBD with self-rated health (SRH) after adjustment for individual-level factors such as socioeconomic status (SES). An area-level PBD indicator was created by aggregating individual-level PBD responses in each tract, representing a proxy for institutionalized PBD, i.e., the concept that living in a stigmatized neighborhood affects neighborhood health. 100 tracts were divided into quartiles in order. The health impact of area-level PBD was compared with that of area-level SES indicators (quartile) such as deprivation. Results After adjustment for individual-level PBD, the highest and third area-level PBD quartiles showed odds ratio (OR) 1.57 (95% credible interval: 1.13-2.18) and 1.38 (0.99-1.92), respectively, for poor SRH compared with the lowest area-level PBD quartile. In a further SES-adjusted model, ORs of area-level PBD (highest and third quartile) were attenuated to 1.32 and 1.31, respectively, but remained marginally significant, although those of the highest area-level not-home-owner (census-based indicator) and deprivation index quartiles were attenuated to 1.26 and 1.21, respectively, and not significant. Individual-level PBD showed significant OR 1.89 (1.33-2.81) for poor SRH in an age, sex, PBD and SES-adjusted model. Conclusion Institutionalized PBD may be a more important environmental determinant of SRH than other area-level SES indicators such as deprivation. Although it may have a smaller health impact than individualized PBD, attention should be paid to invisible and unconscious aspects of institutionalized PBD to improve residents’ health.

Our research on adverse effects of lead exposures on physical and neurobehavioral health of children aged 6-12years in 4 villages, labeled as K, M, L, and X, in rural China, was reported in this article. Lead in blood (PbB), urine (PbU), hairs (PbH), and nails (PbN) were measured by graphite furnace atomic absorption spectrometry. Abbreviated Symptom Questionnaire of Conner's instruments and Revised Raven's Standard Progressive Matrices were applied to evaluate childhood attention deficit/hyperactivity disorders (ADHD) and intelligences. Geometric means (SD) of PbB, PbU, PbH and PbN concentrations were 71.2 microg/L (1.56), 11.7 microg/g (1.75), 12.5 microg/g (2.82), and 25.3 microg/g (2.79), respectively. 54 (17.0%) children had PbB levels of > or =100 microg/L. Boys, 6-10 years old, and living in village K were 2.11, 2.48, and 9.16 times, respectively, more likely to be poisoned by lead than girls, aged 11-12 years, and residing in X. 18 (5.7%) and 37 (11.7%) subjects had ADHD and mental retardations, respectively. Inverse relationships between intelligences and natural log transformed PbU and PbH levels were observed with respective odds ratios (95%CI) of 1.79 (1.00-3.22) and 1.46 (1.06-2.03) or 1.28 (1.04-1.58) and 1.73 (1.18-2.52) by binary or ordinal logistic regression modeling. ADHD prevalence was different by gender and age of subjects. PbU, PbH, and PbN related to PbB positively with respective correlation coefficients of 0.530, 0.477, and 0.181. Receiver operating characteristic (ROC) curves of the three measurements revealed areas under curves (AUCs) being 0.829, 0.758, and 0.687, respectively. In conclusion, children had moderate levels of lead exposures in this rural area. Intelligence declines were associated with internal lead levels among children. ROC analysis suggests PbU an internal lead indicator close to PbB.

Youth homelessness is a problem characterized by high levels of vulnerability. The extent to which couch surfing - moving from one temporary housing arrangement to another - is part of youth homelessness is not well understood. Chapin Hall's Voices of Youth Count, a national research initiative, involves a multicomponent approach to studying youth homelessness. This study reports emerging findings regarding couch surfing and homelessness primarily from a national survey of 13,113 adults with youth ages 13-25 in their households or who are themselves ages 18-25. Findings suggest that couch surfing is relatively common, particularly among the older age group. Among households with 13- to 17-year-olds and 18- to 25-year-olds, 4.0% and 20.5%, respectively, reported that any of them had couch surfed in the last 12 months. There are notable social, economic, and educational differences, on average, between youth reporting homelessness and those reporting only couch surfing. However, most youth who report experiencing homelessness also report couch surfing, and these youth who experience both circumstances present high levels of socioeconomic vulnerability. Couch surfing encompasses a range of experiences, some of which likely include need for services. Interviews currently in the field, and expanded analysis of data, will contribute more nuanced policy insights. © Society for Community Research and Action 2017.

Since 2002, osteopathic medical schools have made curricular changes to further enhance the clinical skills of their students, to prepare them for residency training, and to pass the Comprehensive Osteopathic Medical Licensing Examination-USA Level 2-Performance Evaluation (COMLEX-USA Level 2-PE). To report how students at osteopathic medical schools prepare for the COMLEX-USA Level 2-PE, and to investigate the effect of these techniques on examination performance. A standardized survey was given to students before the beginning of their examination to assess the preparation of osteopathic medical students for the COMLEX-USA Level 2-PE, such as coursework, orientation materials, and standardized patient (SP) encounters. Surveys that were completed by first-time test takers during the 2013-2014 and 2014-2015 test cycles were included in this study. Of 9120 surveys administered, 8733 were completed, achieving a response rate of 95.8%. Of those 8733 respondents, 8706 students (99.7%) reported having SP encounters during the first and second year of medical school, and 7379 (84%) reported having at least 1 SP encounter in years 3 and 4. Of 8733 students, 6079 (70%) reported receiving feedback from an osteopathic physician on their SP encounters, and 6049 (69%) and 6253 (72%) reported having viewed the COMLEX-USA Level 2-PE orientation video online and having read the examination's orientation guide, respectively. The largest difference in preparation between students who passed the COMLEX-USA Level 2-PE and students who did not was a prerequisite SP examination at their school, with 5574 students (68.9%) who passed reporting having participated compared with 364 students (56.5%) who failed. None of the differences in clinical skills training and test preparation was associated with statistically significant differences in pass or fail status. Osteopathic medical students use a variety of methods to enhance their clinical skills in preparation for the COMLEX-USA Level 2-PE, with universal use of SP programs since the COMLEX-USA Level 2-PE was implemented in 2004. Educators should continue to foster ways to develop students' clinical skills that reflect new advances in education and assessment to ensure that future osteopathic physicians can demonstrate competency in fundamental clinical skills before beginning postgraduate training.

This study examined whether the personality traits of self-criticism and dependency respectively moderated the effects of perceived inferiority and emotional insecurity on negative affect during interpersonal interactions in individuals with borderline personality disorder (BPD). A sample of 38 patients with BPD and matched community comparison participants completed event-contingent record forms after each significant interaction for a 20-day period. Multilevel models showed that, controlling for baseline levels of depressive symptoms and neuroticism, as well as lagged negative affect, event-level elevations in perceived inferiority and emotional insecurity were related to more negative affect in both groups. Event-level perceived inferiority was more strongly associated with negative affect in patients with BPD who reported higher levels of self-criticism, while event-level perceived emotional insecurity was more strongly associated with negative affect in patients with BPD who reported higher levels of dependency. No significant interactions emerged for the comparison group. These findings further our understanding of differences among patients with BPD and support the application of personality-vulnerability or diathesis-stress models in predicting negative affect in BPD. Results have implications for the design of therapies for patients with BPD. PsycINFO Database Record (c) 2012 APA, all rights reserved.

Esophageal achalasia can be roughly divided into non-sigmoid and sigmoid types. Laparoscopic surgery has been reported to be less than optimally effective for sigmoid type. The aim of this study was to examine the impact of the esophageal flexion level on the clinical condition and surgical outcomes of patients with sigmoid esophageal achalasia. The subjects were 36 patients with sigmoid esophageal achalasia who had been observed for >1 year after surgery. The subjects were divided into sigmoid type (Sg) and advanced sigmoid type (aSg) groups based on the flexion level of the lower esophagus to compare their clinical parameters and surgical outcomes. The Sg and aSg groups included 26 (72%) and 10 subjects, respectively. There were no marked differences in the clinical parameters or surgical outcomes between the two groups. However, the clearance rate calculated using the timed barium esophagogram was lower in the aSg group than in the Sg group. No differences were found in the postoperative symptom scores between the two groups, and both reported a high level of satisfaction. Although laparoscopic surgery for symptoms of sigmoid esophageal achalasia was highly successful regardless of the flexion level, the improvement in esophageal clearance was lower when the flexion level was higher.

Objectives. We examined whether public schools in states with specific and stringent physical education (PE) laws, as assessed by the Physical Education–Related State Policy Classification System (PERSPCS), available on the Classification of Laws Associated with School Students (C.L.A.S.S.) Web site, reported more weekly PE time in the most recent School Health Policies and Programs Survey (SHPPS). Methods. Schools (n = 410) were grouped by their state’s PERSPCS time requirement scores (none, nonspecific requirement, or specific requirement). Average weekly school-level PE was calculated using the SHPPS-reported PE minutes. Weighted analyses determined if PE minutes/week differed by PERSPCS group. Results. Schools in states with specific requirement laws averaged over 27 and 60 more PE minutes/week at the elementary and middle school levels, respectively, compared with schools within states with nonspecific laws and over 40 and 60 more PE minutes per week, respectively, compared with elementary and middle schools in states with no laws. High school results were nonsignificant. Conclusions. Public health guidelines recommend at least 60 minutes of daily physical activity for children, and PE may further this goal. Strong codified law with specific time requirements for PE may be an important tool contributing toward adequate PE time and daily physical activity recommendations. PMID:22594746

An improved method for the analysis of propylene glycol (PG) in foods using a gas chromatography-flame ionisation detector (GC-FID), with confirmation by GC-MS, was validated by measuring several analytical parameters. The PG concentrations in 1073 products available in Korean markets were determined. PG was detected in 74.1% of the samples, in a concentration range from the limit of detection (n.d., 0.39 μg ml(-1)) to 12,819.9 mg kg(-1). The Korea National Health and Nutrition Examination Survey (KNHANES) 2011-2013 reported the mean intake levels of PG from all sources by the general population and consumers were 26.3 mg day(-1) (0.52 mg kg(-1) day(-1)) and 34.3 mg day(-1) (0.67 mg kg(-1) day(-1)), respectively. The 95th percentile intake levels of the general population and consumers were 123.6 mg day(-1) (2.39 mg kg(-1) day(-1)) and 146.3 mg day(-1) (2.86 mg kg(-1) day(-1)), respectively. In all groups of the general population, breads were the main contributors to the total PG intake. These reports provide a current perspective on the daily intake of PG in the Korean population.

The purpose of this systematic review was to report the effects of gastrocnemius recession on ankle dorsiflexion range of motion, function, and push-off power. The MEDLINE and EMBASE databases were reviewed with terms "gastrocnemius recession". The inclusion criteria were: (1) clinical studies, (2) published in a peer-reviewed journal within the past 10 years, and (3) published in English. Excluded were: (1) review articles, (2) cadaveric studies, (3) studies including patients under the age of 18 years, (4) studies evaluating a neurologic condition, (5) level of evidence 5, and (6) Quality of Evidence Score <3. Data were then extracted and analysed for trends. The PearlDiver Database was also used to review de-identified patient information retrospectively between 2007 and 2011. Full-text review yielded 23 articles that fit the inclusion criteria. Twenty-one of 23 (91%) and 2/23 (9%) studies were level of evidence 4 and 3, respectively. Twelve of 23 (52%) studies reported follow-up assessment between 12 and 36 months, and no studies reported longer-term follow-up. Twelve of 12 (100%) studies reported improved dorsiflexion range of motion 9/9 (100%) reported improved AOFAS, and 11/11 (100%) reported improved VAS. Five of 23 (22%) studies reported strength in a measured and controlled fashion with variable results, but of these, no study reported a return to normal power. The mean complication rate was 14%. The available evidence supports that GR improves functional outcomes and increases dorsiflexion range of motion. Furthermore, GR affects gait kinematics, which may cause compensatory effects at the knee, ankle, and subtalar joints. Evidence has shown that power does not return to normal levels. Clinicians may utilize these data clinically to determine whether patients may benefit from GR or not. IV.

Among the many treatments for erectile dysfunction, implantation of a penile prosthesis has been associated with high patient satisfaction rates. Prosthesis replacement has become an accepted procedure in the event of device malfunction or complications, but to our knowledge, there are no data regarding the impact of implant replacement on patients and partner satisfaction. The aim of our study was to assess and to compare the level of satisfaction, with a first or second penile prosthesis implantation (PPI), in men with refractory erectile dysfunction and their partners. A survey study based on a five-item questionnaire was carried out at our center between January 1999 and January 2012. The main outcome measure used was the level of patient and partner satisfaction with sexual intercourse after PPI. Of the 190 eligible patients, 149 (78%) completed the survey (110 underwent a first implant and 39 a reimplant). Seventy-nine percent of first-time implanted patients and 80% of the reimplanted patients (P > 0.05; not significant [ns]) reported satisfactory sexual intercourse (very or moderately satisfied), while 74% and 80% of their partners reported satisfactory intercourses, respectively (P > 0.05; ns). Overall, 73.7% of first implants and 70% of second implants reported that they would undergo the procedure again if the PPI failed (P > 0.05; ns). With regards to cosmetic aspects, 13% of the first implants' and 15% of second implants' partners reported either penile shortness or soft glans as the main causes of their dissatisfaction. Only 2.4% of first implants and 1% of reimplanted patients expressed difficulty in manipulating the device. PPI is successful in returning the ability for satisfactory sexual intercourse to both first implant and reimplanted patients and their respective partners. © 2015 International Society for Sexual Medicine.

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

The metabolic syndrome (MetSyn) is a significant risk factor for cardiovascular events, but scarce information exists about its frequency in Venezuela. In this cross-sectional study, we quantified the prevalence of the MetSyn in a probabilistic, stratified sample of 274 subjects aged > or =18 years from the Libertador district in Merida, Venezuela. Secondary outcomes were the measurement of thyroid hormones (free T4 and TSH), leptin levels, and insulin resistance index (HOMA2-IR). The frequency of MetSyn (percentage +/- 95% confidence interval) according to several diagnostic criteria was as follows: National Cholesterol Education Panel (NCEP, original): 27.4% (22.1-32.7); modified NCEP: 31.8% (26.3-37.3); International Diabetes Federation: 40.9% (35.1-46.7); Latin American Diabetes Association: 27% (21.7-32.3), and Venezuelan criteria: 31.8% (26.3-37.3). The MetSyn was more frequent in males than in females with most diagnostic criteria. The estimated prevalence of type 2 diabetes mellitus was 2.9% either according to the patients' self reports or to fasting glucose level found to be above 126 mg/dL. Abnormal HOMA2-IR index, free T4 and TSH (above the 95th percentile) were detected in 4.5%, 4.4% and 5.1% of the sample, respectively. Free T4 and TSH levels below the 5th percentile were detected in 4.4% and 4.7% of subjects respectively. These values are presented for comparisons with forthcoming studies in specific clinical populations. While studies are being conducted about the different definitions of the MetSyn in Venezuela, we recommend analyzing and publishing local research data with all the available criteria so as to allow comparisons with the results already reported in the literature.

The antioxidant profile of 23 native Andean potato cultivars has been investigated from a human nutrition perspective. The main carotenoid and tocopherol compounds were studied using high-performance liquid chromatography coupled with a diode array detector (HPLC-DAD) and a fluorescence detector, respectively, whereas polyphenols (including anthocyanins in colored tubers) were identified by means of both HPLC-mass spectrometry and HPLC-DAD. Antioxidant profiling revealed significant genotypic variations as well as cultivars of particular interest from a nutritional point of view. Concentrations of the health-promoting carotenoids, lutein and zeaxanthin, ranged from 1.12 to 17.69 microg g(-1) of dry weight (DW) and from 0 to 17.7 microg g(-1) of DW, with cultivars 704353 and 702472 showing the highest levels in lutein and zeaxanthin, respectively. Whereas beta-carotene is rarely reported in potato tubers, remarkable levels of this dietary provitamin A carotenoid were detected in 16 native varieties, ranging from 0.42 to 2.19 microg g(-1) of DW. The amounts of alpha-tocopherol found in Andean potato tubers, extending from 2.73 to 20.80 microg g(-1) of DW, were clearly above the quantities generally reported for commercial varieties. Chlorogenic acid and its isomers dominated the polyphenolic profile of each cultivar. Dark purple-fleshed tubers from the cultivar 704429 contained exceptionally high levels of total anthocyanins (16.33 mg g(-1) of DW). The main anthocyanin was identified as petanin (petunidin-3-p-coumaroyl-rutinoside-5-glucoside). The results suggest that Andean potato cultivars should be exploited in screening and breeding programs for the development of potato varieties with enhanced health and nutritional benefits.

The presence of thyroid peroxidase antibodies (TPOab) are reported to be associated with improved outcome among breast cancer patients. We evaluated the correlation between TPOab and diagnostic parameters among newly diagnosed breast cancer patients. Three hundred and fourteen newly diagnosed patients with breast cancer, diagnosed and treated in Bethesda Essen between January 2002 and June 2006, were included in this study; 258 (82.2%) without TPOab (≤100 IU/mL) and 56 (17.8%) with TPOab (>100 IU/mL). Blood analysis was performed to measure serum levels of carcinoembryonic antigen (CEA), cancer antigen 15-3 (CA-15-3), free triiodothyronine (fT3), free thyroxine (fT4), thyroid-stimulating hormone (TSH) and TPOab by radioimmunoassay. Data regarding age, tumor size, grading, TNM classification, receptor status, lymph node, and distant metastases were collected and analyzed from patient reports. Statistics were performed using Pearson’s χ2-test and logistic regression analysis. There were no incidences of distant metastasis among 56 patients with TPOab, whereas 17 (6.6%) of 258 cases without TPOab displayed distant metastases (p=0.04). Logistic regression showed an inverse association of TPOab with CA-15-3 and CEA levels (p<0.001, respectively). Both groups, with and without TPOab, revealed no significant differences with respect to age, tumor size, grading, TNM classification, fT3, fT4, and receptor status. TPOab positive patients had higher TSH levels (2.55±3.58), compared to TPOab negative cases (1.20±1.15) (p<0.001). TPOab occurrence is associated with significantly lower frequency of distant metastases in breast cancer. TPOab level inversely correlates with the conventional tumor markers CA-15-3 and CEA.

We pooled data from 5 large validation studies of dietary self-report instruments that used recovery biomarkers as references to clarify the measurement properties of food frequency questionnaires (FFQs) and 24-hour recalls. The studies were conducted in widely differing US adult populations from 1999 to 2009. We report on total energy, protein, and protein density intakes. Results were similar across sexes, but there was heterogeneity across studies. Using a FFQ, the average correlation coefficients for reported versus true intakes for energy, protein, and protein density were 0.21, 0.29, and 0.41, respectively. Using a single 24-hour recall, the coefficients were 0.26, 0.40, and 0.36, respectively, for the same nutrients and rose to 0.31, 0.49, and 0.46 when three 24-hour recalls were averaged. The average rate of under-reporting of energy intake was 28% with a FFQ and 15% with a single 24-hour recall, but the percentages were lower for protein. Personal characteristics related to under-reporting were body mass index, educational level, and age. Calibration equations for true intake that included personal characteristics provided improved prediction. This project establishes that FFQs have stronger correlations with truth for protein density than for absolute protein intake, that the use of multiple 24-hour recalls substantially increases the correlations when compared with a single 24-hour recall, and that body mass index strongly predicts under-reporting of energy and protein intakes.

To investigate cross-cultural validity of a simple self-report instrument of physical activity intended to be used in Swedish health care. A validation study performed in 599 Iraqis (58% men) and 553 Swedes (53% men) aged 30-75 years living in the city of Malmö, Sweden. The self-report instrument by the Swedish National Board of Health and Welfare was compared to corresponding measures assessed from accelerometry as reference. The agreement between the methods in assessing the participants as sufficiently/insufficiently physically active (cut-point 150 min/week) was 65% in the Iraqis and 52% in the Swedes (p<0.001). The proportion disagreement where the self-reported physical activity was sufficient but insufficient according to the accelerometry was 26% and 45% in Iraqis and Swedes, respectively. Physical activity time (min/week) was overestimated by self-report compared to accelerometry by 71% in the Iraqis and 115% in the Swedes (p<0.001). The smallest and largest overestimation was seen in Iraqi (57%) and Swedish (139%) women, respectively. The deviation of the self-report instrument compared to accelerometry was related to the physical activity level, as the overestimation mainly occurred at lower physical activity. The self-report instrument proposed by the Swedish National Board of Health and Welfare may overestimate the proportion sufficiently physically active, but to an extent depending on cultural background and gender.

Both the physical self-concept and actual motor competence are important for healthy future physical activity levels and consequently decrease overweight and obesity in childhood. However, children scoring high on motor competence do not necessarily report high levels of physical self-concept and vice versa, resulting in respective (in-) accuracy also referred to as (non-) veridicality. This study examines whether children's accuracy of physical self-concept is a meaningful predictive factor for their future physical activity. Motor competence, physical self-concept and physical activity were assessed in 3 rd grade and one year later in 4 th grade. Children's weight status was categorized based on WHO recommendations. Polynomial regression with Response surface analyses were conducted with a quasi-DIF approach examining moderating weight status effects. Analyses revealed that children with higher motor competence levels and higher self-perceptions show greater physical activity. Importantly, children who perceive their motor competence more accurately (compared to less) show more future physical activity. This effect is strong for underweight and overweight/obese children, but weak for normal weight children. This study indicates that an accurate self-perception of motor competence fosters future physical activity beyond single main effects, respectively. Hence, the promotion of actual motor competence should be linked with the respective development of accurate self-knowledge.

Complete and accurate pathology reporting of colorectal carcinoma (CRC) resection specimen is critical to clinical management of individual patients. The study aims to audit colorectal cancer histopathology reporting in Lagos between 2011 and 2015 before the adoption of the Society for Gastroenterology and Hepatology in Nigeria pro forma in 2016. All resected CRC cases were identified from the Histopathology record of our Department and that of a private Laboratory in Lagos over a 5-year from 2011 to 2015. The dataset as contained in the pro forma was extracted from the reports and analysed using SPSS version 16 software. A total of 92 colorectal resections were received during the 5-year period consisting of 90 colonic and 2 rectal tumours. Data inclusiveness on tumour differentiation, extent of primary tumour, total lymph node and lymph node involvement were 96.7%, 91.3%, 83.7% and 92.4%, respectively. Tumour perforation, level of venous involvement and distant metastasis were reported in 73.9%, 21.7% and 96.7% respectively. The circumferential resection margin (CRM) in the 2 rectal tumours had 100% inclusiveness. Tumour node metastasis staging was complete in 87% of cases while Dukes staging was documented in 8.7% of the reports. None of the data items was 100% complete except the CRM for rectal carcinoma. Free text reporting results in incomplete data resulting in improper staging, especially the lymph node status. This highlights the need for pro forma reporting to ensure and maintain consistent reporting of important parameters required for proper staging and management of patients with colorectal cancer.

Spondylolytic defects involving multiple vertebral levels are rare. It is reported that only 1.48% of patients with back pain were diagnosed with multi-level spondylolysis. The incidence of multiple-level spondylolisthesis is even rarer, so far there have been few reports of multi-level isthmic spondylolisthesis in the literature. The aim of this study is to evaluate clinical and radiological outcomes of two different fusion techniques for treatment of double-level isthmic spondylolisthesis. Fifty-four patients who were managed surgically for treatment of double-level symptomatic isthmic spondylolisthesis were included in this study. Between May 2004 and September 2012, 29 consecutive patients underwent posterior lumbar interbody fusion (PLIF) with autogenous bone chips (group I) at Foshan Hospital of Traditional Chinese Medicine, Guangdong, China. Between March 2005 and December 2013, 25 consecutive patients underwent PLIF with cage (group II) at Zhujiang Hospital of Southern Medical University, Guangdong, China. The mean follow-up periods were 27.2 and 26.8 months, respectively. The mean VAS scores of back and leg pain significantly decreased from 7.2 to 2.2 and 5.8 to 2.1 in the group I and from 7.0 to 1.9 and 6.1 to 1.8 in the group II, respectively. In the group I, mean ODI scores improved significantly from 54% to 14.2% and, in the group II, from 60% to 12.6%. In both groups, VAS and ODI scores significantly changed from pre- to postoperatively (p<0.001), but postoperative outcome between groups was statistically not significant. Solid union was observed in 27 of 29 patients (89.6%) in the group I and in 22 of 25 patients (88%) in the group II, without statistically significant differences (p>0.05). In both groups, changes in disc height, degree of listhesis, and whole lumbar lordosis between the pre- and postoperative periods were significant. Clinical and functional outcomes demonstrate no significant differences between groups in treating back and leg pain of adult patients with double-level isthmic spondylolisthesis.

2015-01-01

Objective To analyse the results from the first 3 years of implementation of a medical error reporting system in Médecins Sans Frontières-Operational Centre Amsterdam (MSF) programs. Methodology A medical error reporting policy was developed with input from frontline workers and introduced to the organisation in June 2010. The definition of medical error used was “the failure of a planned action to be completed as intended or the use of a wrong plan to achieve an aim.” All confirmed error reports were entered into a database without the use of personal identifiers. Results 179 errors were reported from 38 projects in 18 countries over the period of June 2010 to May 2013. The rate of reporting was 31, 42, and 106 incidents/year for reporting year 1, 2 and 3 respectively. The majority of errors were categorized as dispensing errors (62 cases or 34.6%), errors or delays in diagnosis (24 cases or 13.4%) and inappropriate treatment (19 cases or 10.6%). The impact of the error was categorized as no harm (58, 32.4%), harm (70, 39.1%), death (42, 23.5%) and unknown in 9 (5.0%) reports. Disclosure to the patient took place in 34 cases (19.0%), did not take place in 46 (25.7%), was not applicable for 5 (2.8%) cases and not reported for 94 (52.5%). Remedial actions introduced at headquarters level included guideline revisions and changes to medical supply procedures. At field level improvements included increased training and supervision, adjustments in staffing levels, and adaptations to the organization of the pharmacy. Conclusion It was feasible to implement a voluntary reporting system for medical errors despite the complex contexts in which MSF intervenes. The reporting policy led to system changes that improved patient safety and accountability to patients. Challenges remain in achieving widespread acceptance of the policy as evidenced by the low reporting and disclosure rates. PMID:26381622

Prostate cancer is the most common cancer among men in the United States with striking differences in incidence and mortality among ethnic groups. Michigan has one of the largest concentrations of Arab Americans (AAs) in the U.S. and little is known about this ethnic minority with respect to prostate cancer. This study investigated differences in clinical profile, quality of care, and recurrence among prostate cancer survivors comparing AAs and Caucasian Americans (CAs). Participants in this study included 2499 prostate cancer survivors from the Michigan Cancer Registry from 1985 to 2004. Participants completed surveys regarding health-seeking behavior, post-treatment symptoms, quality of care and recurrence. Ethnicity was self-reported and AAs and CAs were compared with respect to clinical profile, quality of care, and recurrence. There were 52 AAs and 1886 CAs patients with AAs being younger (x̄ age 68.3 ± SD 21.4 years, x̄ age 72.3 ± SD 14.1 years, for AAs and CAs, respectively) (P = 0.05). AAs had lower socioeconomic standard than CAs (34 vs. 10.6 %, <$20,000 yearly income/year; for AAs vs. CAs, respectively) (P < 0.0001). AAs reported poorer health than AAs (7.7 vs. 3.0 % for AAs vs. CAs, respectively) (P < 0.0001). AAs were more likely to visit specialists for prostate follow-up (44.5 vs. 19.7 % visited a specialist, for AAs vs. CAs respectively) (P < 0.0001) and received supplementary healthcare workers (13 % of AAs vs. 3.1 % CAs) (P = 0.032). In addition, AAs reported higher occurrence of urinary incontinence compared to CAs (67.4 vs. 60.4 %, for AAs vs. CAs, respectively) (P = 0.001). Ethnic background was not a predictor of recurrence [(Odds ratio (OR) = 1.1 (95 % confidence intervals CI = 0.40, 2.9)] (P = 0.873) even after adjusting for age, PSA levels within the last 2 years, metastasis and hormonal therapy. While AAs prostate cancer patients were different from CAs in age, income, seeking medical care, and health reporting, ethnic background was not a predictor of recurrence. Future studies of the impact of socioeconomic, demographic and cultural factors, and health care seeking behavior on long-term survival of prostate cancer in AAs and other ethnic minorities are warranted.

Tracking progress toward global polio eradication, 2010-2011.

PubMed

2012-04-20

In January 2012, polio eradication was declared a "programmatic emergency for global public health" by the Executive Board of the World Health Organization (WHO). Since the Global Polio Eradication Initiative (GPEI) began in 1988, progress has been tracked by surveillance of acute flaccid paralysis (AFP) cases and testing of linked stool specimens for polioviruses (PVs) in WHO-accredited Global Polio Laboratory Network (GPLN) laboratories, complemented by sewage testing (environmental surveillance) in selected areas. Monitoring AFP surveillance quality at national and subnational administrative levels using standard performance indicators identifies potential gaps where PV circulation might go undetected; monitoring specimen transport and laboratory reporting timeliness identifies areas where reporting delays could lead to late response, permitting ongoing transmission. This report provides an assessment of 2010-2011 performance indicators for AFP surveillance at national and subnational levels in polio-affected countries and laboratory reporting at the regional level, updated from 2009-2010. Overall, 16 (62%) of 26 countries with circulating wild PV (WPV) met national AFP surveillance indicator targets during both 2010 and 2011. All three countries with reestablished WPV transmission and 16 of 19 countries with WPV outbreaks had substantial proportions (>20%) of their respective populations living in areas with underperforming surveillance during 2010 or 2011. Targets for timely reporting of PV isolation and type characterization results were met in three of six WHO regions in 2010 and five regions in 2011. To achieve polio eradication, efforts are needed to improve AFP surveillance and laboratory performance.

In elite-level soccer, player motion characteristics are commonly generated from match play and training situations using semiautomated video analysis systems and global positioning system (GPS) technology, respectively. Before such data are used collectively to quantify global player load, it is necessary to understand both the level of agreement and direction of bias between the systems so that specific interventions can be made based on the reported results. The aim of this report was to compare data derived from both systems for physical match performances. Six elite-level soccer players were analyzed during a competitive match using semiautomated video analysis (ProZone® [PZ]) and GPS (MinimaxX) simultaneously. Total distances (TDs), high speed running (HSR), very high speed running (VHSR), sprinting distance (SPR), and high-intensity running distance (HIR; >4.0 m·s(-1)) were reported in 15-minute match periods. The GPS reported higher values than PZ did for TD (GPS: 1,755.4 ± 245.4 m; PZ: 1,631.3 ± 239.5 m; p < 0.05); PZ reported higher values for SPR and HIR than GPS did (SPR: PZ, 34.1 ± 24.0 m; GPS: 20.3 ± 15.8 m; HIR: PZ, 368.1 ± 129.8 m; GPS: 317.0 ± 92.5 m; p < 0.05). Caution should be exercised when using match-load (PZ) and training-load (GPS) data interchangeably.

Previous studies suggest that periodontitis is closely related to obesity and metabolic syndrome. Leptin, a pleiotrophic hormone produced by adipose tissue, has been reported to be related to periodontitis. This study investigates the effects of periodontal treatment on the serum levels of leptin and other cytokines in patients with chronic periodontitis (CP). Serum samples were taken from 33 CP patients (22 non-smokers, 11 smokers) and 18 healthy subjects. The serum leptin, adiponectin, tumor necrosis factor-alpha, interleukin (IL)-6, and C-reactive protein (CRP) levels were measured before and after non-surgical periodontal treatment. Significant differences between healthy and CP patients were found in serum leptin, IL-6, and CRP levels (P = 0.0018, P = 0.0064, and P = 0.0095, respectively). The serum leptin level was associated with mean probing depth, mean clinical attachment level, mean alveolar bone loss, and body mass index. There were significant associations between serum leptin levels and IL-6 and CRP levels. After non-surgical periodontal treatment, serum leptin, IL-6, and CRP levels were significantly decreased (mean +/- SD before and after, P value, respectively: leptin, 8.02 +/- 5.5, 7.10 +/- 4.4, P = 0.015; IL-6, 1.73 +/- 1.02, 1.36 +/- 0.73, P = 0.048; and CRP, 802.0 +/- 1065, 491.2 +/- 479.3, P = 0.047). Periodontal treatment is effective in reducing serum leptin, IL-6, and CRP levels. The results suggest that leptin, IL-6, and CRP could be mediating factors that connect metabolic syndrome and periodontitis.

We report on a patient with androgen ablation-refractory prostate adenocarcinoma who had an objective response for longer than 24 months using a combination of estramustine and lanreotide. At baseline from our combination therapy, his prostate-specific antigen level was 21.30 ng/mL and serum chromogranin A level was 816 ng/mL. The patient discontinued complete androgen deprivation therapy and underwent combination therapy with oral estramustine 420 mg/day plus lanreotide acetate 73.9 mg intramuscularly every 4 weeks. After 33 months of follow-up, the patient was alive without clinical disease progression, and his prostate-specific antigen and chromogranin A level was 0.10 and 12 ng/mL, respectively.

This paper reports a 130-nm CMOS programmable cascade ΣΔ modulator for multi-standard wireless terminals, capable of operating on three standards: GSM, Bluetooth and UMTS. The modulator is reconfigured at both architecture- and circuit- level in order to adapt its performance to the different standards specifications with optimized power consumption. The design of the building blocks is based upon a top-down CAD methodology that combines simulation and statistical optimization at different levels of the system hierarchy. Transistor-level simulations show correct operation for all standards, featuring 13-bit, 11.3-bit and 9-bit effective resolution within 200-kHz, 1-MHz and 4-MHz bandwidth, respectively.

Scombroid fish poisoning is usually associated with consumption of fish containing high levels of histamine. However, reports indicate that some cases have responded to antihistamine therapy while ingested histamine levels in these cases were low. Potentiation of histamine toxicity by some biogenic amines, and release of endogenous histamine by other compounds such as cis-urocanic acid (UCA) are some hypotheses that have been put forth to explain this anomaly. Very little is known about the effects of storage conditions on the production of both UCA isomers and biogenic amines in tuna. Thus, the production of trans- and cis-UCA, histamine, putrescine, and cadaverine in tuna during 15 d of storage at 0, 3, and 10 °C and 2 d storage at ambient temperature were monitored. The initial trans- and cis-UCA contents in fresh tuna were 2.90 and 1.47 mg/kg, respectively, whereas the levels of putrescine and cadaverine were less than 2 mg/kg, and histamine was not detected. The highest levels of trans- and cis-UCA were obtained during 15 d storage at 3 °C (23.74 and 21.79 mg/kg, respectively) while the highest concentrations of histamine (2796 mg/kg), putrescine (220.32 mg/kg) and cadaverine (1045.20 mg/kg) were obtained during storage at room temperature, 10 and 10 °C, respectively. Histamine content increased considerably during storage at 10 °C whereas trans- and cis-UCA contents changed slightly. The initial trans-UCA content decreased during storage at ambient temperature. Thus, unlike histamine, concentrations of trans- and cis-UCA did not result in elevated levels during storage of tuna. © 2015 Institute of Food Technologists®

Predictors of Satisfaction With Doctor and Nurse Communication: A National Study.

Prior research indicates that effective communication between medical providers and patients is associated with a number of positive patient outcomes, yet little research has examined how ecological factors (e.g., hospital size, local demographics) influence patients' reported satisfaction with doctor and nurse communication. Given the current emphasis on improving patient satisfaction in hospitals across the United States, understanding these factors is critical to interpreting patient satisfaction and improving patient-centered communication, particularly in diverse and dense populations. As such, this study examined county-level data including population density, population diversity, and hospital structural factors as predictors of patient satisfaction with doctor and nurse communication. Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS), U.S. Census data, and number of hospital beds were obtained from publicly available Hospital Compare, U.S. Census, and American Hospital Directory websites, respectively. Multivariate regression modeling was performed for the individual dimensions of HCAHPS scores assessing doctor and nurse communication. Standardized partial regression coefficients were used to assess strengths of county-level predictors. County-level factors accounted for 30% and 16% of variability in patient satisfaction with doctor and nurse communication, respectively. College education (β = 0.45) and White ethnicity (β = 0.25) most strongly predicted a favorable rating of doctor and nurse communication, respectively. Primary language (non-English speaking; β = -0.50) most strongly predicted an unfavorable rating of doctor communication, while number of hospital beds (β = -0.16) and foreign-born (β = -0.16) most strongly predicted an unfavorable rating of nurse communication. County-level predictors should be considered when interpreting patient satisfaction with doctor and nurse communication and designing multilevel patient-centered communication improvement strategies. Discordant findings with individual-level factors should be explored further.

We describe an evaluation of the effects of partial Roux-en-Y gastric bypass (RYGB) reversal on postprandial hyperinsulinaemic hypoglycaemia, insulin and GLP-1 levels. A 37 year old man was admitted with neuroglycopenia (plasma-glucose 1.6mmol/l) 18 months after RYGB, with normal 72h fasting test and abdominal CT. Despite dietary modifications and medical treatment, the hypoglycaemic episodes escalated in frequency. Feeding by a gastrostomy tube positioned in the gastric remnant did not prevent severe episodes of hypoglycaemia. A modified reversal of the RYGB was performed. Mixed meal tests were done perorally (PO), through the gastrostomy tube 1 (GT1), 4 weeks (GT2) after placement and 4 weeks after reversal (POr), with assessment of glucose, insulin and GLP-1 levels. Plasma-glucose increased to a maximum of 9.6, 5.4, 6.5 and 5.8mmol/l at the PO, GT1, GT2 and POr tests respectively. The corresponding insulin levels were 2939, 731, 725 and 463pmol/l. A decrease of plasma-glucose followed: 2.2, 3.0, 3.9 and 2.9mmol/l respectively and insulin levels were suppressed at 150min: 45, 22, 21 and 14pmol/l, respectively. GLP-1 levels increased in the PO test (60min: 122pmol/l, 21 fold of basal), but was attenuated in the two latter tests (12-23pmol/l at 60min). Reduction of plasma-glucose, insulin and GLP-1 excursions and symptoms were seen after gastric tube placement and partial RYGB reversal. This attenuation of GLP-1 response to feeding could reflect an adaptation to nutrients. Copyright © 2016. Published by Elsevier Ltd.

The present study was developed to comprehensively investigate the occupational health problems among teachers of primary and secondary schools in Hong Kong. A random sample of 1,710 respondents was generated from the database of Hong Kong Professional Teachers' Union (HKPTU) members. A self-administrated questionnaire was designed and sent by mail to the teachers of primary and secondary schools in HK. The results indicated that comparing with one year and five years ago, 91.6% and 97.3% of the responding teachers reported an increase of perceived stress level, respectively. Heavy workload and time pressure, education reforms, external school review, pursuing further education, and managing students' behaviour and learning were the most frequently reported sources of work stress. The four most frequently reported stress management activities were sleeping, talking to neighbors and friends, self-relaxing, and watching television, while the least frequently reported activity was doing more exercises or sports.

A survey of key indoor air quality (IAQ) parameters and resident health was carried out in 72 apartments within a single low-income senior housing building in Phoenix, Arizona. Air sampling was carried out simultaneously with a questionnaire on personal habits and general health of residents. Mean PM10 concentrations are 66 +/- 16, 58 +/- 13, and 24 +/- 3 microg/m3 and mean PM2.5 concentrations are 62 +/- 16, 53 +/- 13, and 20 +/- 2 microg/m3 for the living room, kitchen, and outdoor balcony, respectively. Median PM10 concentrations are 17, 18 and 17 microg/m3 and median PM25 concentrations are 13, 14, and 13 microg/m3, respectively. The initial results indicate that increased indoor particle concentrations coincide with residents who report smoking cigarettes. Indoor formaldehyde concentrations revealed median levels of 36.9, 38.8, and 4.3 ppb in the living room, kitchen, and balcony, respectively. Results show that 36% of living room samples and 44% of kitchen samples exceeded the Health Canada REL for chronic exposure to formaldehyde (40 ppb). Associations between occupants' behavior self-reported health conditions, and IAQ are evaluated.

To explore the value of Prostate Imaging Reporting and Data System Version 2 (PI-RADS v2) for predicting prostate biopsy results in patients with prostate specific antigen (PSA) levels of 4-10 ng/ml. We retrospectively reviewed multi-parameter magnetic resonance images from 528 patients with PSA levels of 4-10 ng/ml who underwent transrectal ultrasound-guided prostate biopsies between May 2015 and May 2017. Among them, 137 were diagnosed with prostate cancer (PCa), and we further subdivided them according to pathological results into the significant PCa (S-PCa) and insignificant significant PCa (Ins-PCa) groups (121 cases were defined by surgical pathological specimen and 16 by biopsy). Age, PSA, percent free PSA, PSA density (PSAD), prostate volume (PV), and PI-RADS score were collected. Logistic regression analysis was performed to determine predictors of pathological results. Receiver operating characteristic curves were constructed to analyze the diagnostic value of PI-RADS v2 in PCa. Multivariate analysis indicated that age, PV, percent free PSA, and PI-RADS score were independent predictors of biopsy findings, while only PI-RADS score was an independent predictor of S-PCa (P < 0.05). The areas under the receiver operating characteristic curve for diagnosing PCa with respect to age, PV, percent free PSA, and PI-RADS score were 0.570, 0.430, 0.589 and 0.836, respectively. The area under the curve for diagnosing S-PCa with respect to PI-RADS score was 0.732. A PI-RADS score of 3 was the best cutoff for predicting PCa, and 4 was the best cutoff for predicting S-PCa. Thus, 92.8% of patients with PI-RADS scores of 1-2 would have avoided biopsy, but at the cost of missing 2.2% of the potential PCa cases. Similarly, 83.82% of patients with a PI-RADS score ≤ 3 would have avoided biopsy, but at the cost of missing 3.3% of the potential S-PCa cases. PI-RADS v2 could be used to reduce unnecessary prostate biopsies in patients with PSA levels of 4-10 ng/ml.

Prevalence of and Risk Factors for Tinnitus and Tinnitus-Related Handicap in a College-Aged Population.

PubMed

Bhatt, Ishan Sunilkumar

Tinnitus is a common otological condition that affects almost 10% of US adults. Research suggests that college students are vulnerable to tinnitus and hearing loss as they are exposed to traumatic levels of noise on a regular basis. Tinnitus and its influence in daily living continue to be underappreciated in the college-aged population. Therefore, the objective for the present study was to analyze prevalence and associated risk factors of tinnitus and tinnitus-related handicap in a sample of college-aged students. A survey was administered to 678 students aged 18-30 years in a cross-section of randomly selected university classes. The survey was adopted from the National Health and Nutrition Examination Survey (2010). It inquired about demographic details, medical and audiological history, routine noise exposure, smoking, sound level tolerance, tinnitus, and tinnitus-related handicap in daily living. Tinnitus-related handicap was assessed by the Tinnitus Handicap Inventory (THI). Participants were divided into four groups: chronic tinnitus (bothersome tinnitus for >1 year), acute tinnitus (bothersome tinnitus for ≤1 year), subacute tinnitus (at least one experience of tinnitus in a lifetime), and no tinnitus (no experience of tinnitus in a lifetime). The prevalence of chronic, acute, subacute, and no tinnitus was 8.4%, 13.0%, 37.9%, and 40.7% respectively. Almost 9% of subjects with any form of tinnitus reported more than a slight tinnitus-related handicap (i.e., THI score ≥18). A multinomial regression analysis revealed that individuals with high noise exposure, high sound level tolerance score, recurring ear infections, and self-reported hearing loss had high odds of chronic tinnitus. Females showed higher prevalence of acute tinnitus than males. Individuals with European American ethnicity and smoking history showed high odds of reporting subacute tinnitus. Almost 10% of the subjects reported that they were music students. The prevalence of chronic, acute, and subacute tinnitus was 11.3%, 22.5%, and 32.4%, respectively, for musicians, which was significantly higher than that for nonmusicians. Music exposure, firearm noise exposure, and occupational noise exposure were significantly correlated with tinnitus. Temporal characteristics of tinnitus, self-reported tinnitus loudness, and sound level tolerance were identified as major predictors for the overall THI score. Despite the reluctance to complain about tinnitus, a substantial portion of college-aged individuals reported tinnitus experience and its adverse influence in daily living. It was concluded that environmental and health-related factors can trigger tinnitus perception, while self-reported psychoacoustic descriptors of tinnitus may explain perceived tinnitus-related handicap in daily living by college-aged individuals. Future research is required to explore effects of tinnitus on educational achievements, social interaction, and vocational aspects of college students.

To study the feasibility and results of the self-reported short diet quality screener (sDQS) in Primary Care. The variables associated with difficulty and inadequate diet are also determined. Cross-sectional descriptive study conducted with 196 participants aged >18 years with diabetes mellitus, hypertension, or hypercholesterolaemia, consecutively included from 4 Primary Health Care Centres in Barcelona. The main variables collected were, age, sex, educational level, cardiovascular risk factors, body mass index, time to complete the sDQS, degree of difficulty, and diet score: inadequate diet ≤18, adequate in some aspects 19-27, adequate >27. The mean age was 48.8 years (52% males). The analysis of the variables showed that the prevalence of having higher than a primary education level, hypertension, diabetes, hypercholesterolemia, and obesity was 50%, 54.6%, 23.5%, 56.6%, and 27.5%, respectively. The mean time to complete the questionnaire was 2.3min. More than 80% considered it easy or very easy. An inadequate diet was reported by 21.4%, adequate in some aspects by 76.5%, and an adequate diet only by 2%. To be older than 49 years and a low diet quality increased the risk of needing ≥2min to complete the sDQS (OR 2.0, 95% CI; 1.0-4.3, and OR 2.3, 95% CI; 1.1-5.1, respectively). Not following a low cholesterol diet and age less than 49 years increased the risk of a low diet quality (OR 2.2; 95% CI: 1.1-4.5, and OR 2.9; 95% CI: 1.2-6.8, respectively). The completion of the sDQS is easy and was not a significant time-burden in Primary Care. A significant proportion of participants with cardiovascular risk reported a low diet quality.

Effects of blood triglycerides on cardiovascular and all-cause mortality: a systematic review and meta-analysis of 61 prospective studies

PubMed Central

2013-01-01

The relationship of triglycerides (TG) to the risk of death remains uncertain. The aim of this study was to determine the associations between blood triglyceride levels and cardiovascular diseases (CVDs) mortality and all-cause mortality. Four databases were searched without language restriction for relevant studies: PubMed, ScienceDirect, EMBASE, and Google Scholar. All prospective cohort studies reporting an association between TG and CVDs or all-cause mortality published before July 2013 were included. Risk ratios (RRs) with 95% confidence intervals (CIs) were extracted and pooled according to TG categories, unit TG, and logarithm of TG using a random-effects model with inverse-variance weighting. We identified 61 eligible studies, containing 17,018 CVDs deaths in 726,030 participants and 58,419 all-cause deaths in 330,566 participants. Twelve and fourteen studies, respectively, reported the effects estimates of CVDs and total mortality by TG categories. Compared to the referent (90–149 mg/dL), the pooled RRs (95% CI) of CVDs mortality for the lowest (< 90 mg/dL), borderline-high (150–199 mg/dL), and high TG (≥ 200 mg/dL) groups were 0.83 (0.75 to 0.93), 1.15 (1.03 to 1.29), and 1.25 (1.05 to 1.50); for total mortality they were 0.94 (0.85 to 1.03), 1.09 (1.02 to 1.17), and 1.20 (1.04 to 1.38), respectively. The risks of CVDs and all-cause deaths were increased by 13% and 12% (p < 0.001) per 1-mmol/L TG increment in twenty-two and twenty-two studies reported RRs per unit TG, respectively. In conclusion, elevated blood TG levels were dose-dependently associated with higher risks of CVDs and all-cause mortality. PMID:24164719

The Waste Pretreatment and Interfacing Systems Dynamic Simulation Model was created to investigate the required pretreatment facility processing rates for both high level and low level waste so that the vitrification of tank waste can be completed according to the milestones defined in the Tri-Party Agreement (TPA). In order to achieve this objective, the processes upstream and downstream of the pretreatment facilities must also be included. The simulation model starts with retrieval of tank waste and ends with vitrification for both low level and high level wastes. This report describes the results of three simulation cases: one based on suggestedmore » average facility processing rates, one with facility rates determined so that approximately 6 new DSTs are required, and one with facility rates determined so that approximately no new DSTs are required. It appears, based on the simulation results, that reasonable facility processing rates can be selected so that no new DSTs are required by the TWRS program. However, this conclusion must be viewed with respect to the modeling assumptions, described in detail in the report. Also included in the report, in an appendix, are results of two sensitivity cases: one with glass plant water recycle steams recycled versus not recycled, and one employing the TPA SST retrieval schedule versus a more uniform SST retrieval schedule. Both recycling and retrieval schedule appear to have a significant impact on overall tank usage.« less

The purpose of this study was to examine the relationship between social worker reports and the fatty acid ethyl ester (FAEE) test as a biomarker for heavy alcohol use. In 2005, a diagnostic program to detect excessive alcohol use by FAEE hair analysis in parents at high risk of having children with fetal alcohol spectrum disorders was established. All cases submitted by Child Protective Services between May and December of 2007 (n = 172) were included comparing social worker reports with FAEE test outcome by odds ratio analysis. A subanalysis of mothers (n = 119), excluding fathers, was also performed. Factors associated with testing positive for hair FAEE in parents, and mothers alone, were: knowledge of a specific instance of problem drinking within the past 6 months (odds ratio [OR] = 5.11, 2.57-10.16 and OR = 8.51, 3.59-20.18, respectively) and third party reports alleging alcohol abuse (OR = 3.31, 1.69-6.46 and OR = 3.30, 1.45-7.50, respectively). Mothers who admitted to heavy drinking were also seven times more likely to test positive for hair FAEE (OR = 6.74, 1.50-30.38) than those who did not. Factors negatively associated with testing positive for hair FAEE in parents, and mothers alone, were: social workers testing for FAEE without the suspicion of alcohol use but rather as a measure to "cover all bases" (OR = 0.09, 0.02-0.40 and (OR = 0.13, 0.03-0.58, respectively) or because of a history/suspicion of illicit drug use (OR = 0.2, 0.07-0.55 and OR = 0.26, 0.08-0.80, respectively). Eleven of 15 reports, indicating levels of consumption, were also in clinical agreement with FAEE test outcome. The FAEE hair test is being applied for the first time in the present context. Our results show the test corroborates well with social workers' suspicion of alcohol use. Reported factors directly related to alcohol use were significantly associated with testing positive for excessive alcohol use, whereas factors not directly related to alcohol use were negatively associated with testing positive.

Polycystic ovary syndrome (PCOS) and hypothalamic amenorrhea (HA) are the most frequent causes of endocrine infertility, but their association is an uncommon occurrence. We report the case of a 28-year old woman suffering from infertility and amenorrhea. Her weight was normal (BMI = 19) and she had no hirsutism. She self-reported food restriction and a 10 kg weight loss 5 years ago, concomitant with the onset of amenorrhea. At the initial evaluation, the patient was considered as having HA due to food restriction. At ultrasonography, ovaries were small and multifollicular (right and left area: 2.2 and 2.5 cm(2), respectively; number of cysts 2-9 mm in diameter: 15 and 12, respectively), and no stromal hypertrophy was noted. She has been treated for 1 month by intravenous pulsatile GnRH administration. Although the doses were increased from 5 to 15 microg/pulse every 90 min, no E2 response and no follicular development were observed. Hormonal re-evaluation revealed normal levels of serum LH, FSH and androgens, and a normal LH/FSH ratio. However, a typical aspect of PCO was found at ultrasound (right and left area: 6.5 and 5.5 cm(2), respectively, and more than 15 small cysts arranged peripherally around an increased central stroma in each ovary). The treatment has been then switched to hMG, using the low dose step-up regimen and starting with 75 U/day. In the absence of response after 2 weeks, the dose was increased to 112.5 U/day and a multifollicular reaction occurred, leading to cancellation. In conclusion, we hypothesize that this patient had a "hidden" PCOS when she was hypogonadotrophic and that it developed very rapidly after restitution of a normal gonadotropin level under exogenous GnRH. This occurred despite a low insulin level, showing that hyperinsulinism is not a prerequisite for the development of PCOS in every case.

Objective  To map the diverse health outcomes associated with serum uric acid (SUA) levels. Design  Umbrella review. Data sources  Medline, Embase, Cochrane Database of Systematic Reviews, and screening of citations and references. Eligibility criteria  Systematic reviews and meta-analyses of observational studies that examined associations between SUA level and health outcomes, meta-analyses of randomised controlled trials that investigated health outcomes related to SUA lowering treatment, and Mendelian randomisation studies that explored the causal associations of SUA level with health outcomes. Results  57 articles reporting 15 systematic reviews and144 meta-analyses of observational studies (76 unique outcomes), 8 articles reporting 31 meta-analyses of randomised controlled trials (20 unique outcomes), and 36 articles reporting 107 Mendelian randomisation studies (56 unique outcomes) met the eligibility criteria. Across all three study types, 136 unique health outcomes were reported. 16 unique outcomes in meta-analyses of observational studies had P<10 -6 , 8 unique outcomes in meta-analyses of randomised controlled trials had P<0.001, and 4 unique outcomes in Mendelian randomisation studies had P<0.01. Large between study heterogeneity was common (80% and 45% in meta-analyses of observational studies and of randomised controlled trials, respectively). 42 (55%) meta-analyses of observational studies and 7 (35%) meta-analyses of randomised controlled trials showed evidence of small study effects or excess significance bias. No associations from meta-analyses of observational studies were classified as convincing; five associations were classified as highly suggestive (increased risk of heart failure, hypertension, impaired fasting glucose or diabetes, chronic kidney disease, coronary heart disease mortality with high SUA levels). Only one outcome from randomised controlled trials (decreased risk of nephrolithiasis recurrence with SUA lowering treatment) had P<0.001, a 95% prediction interval excluding the null, and no large heterogeneity or bias. Only one outcome from Mendelian randomisation studies (increased risk of gout with high SUA levels) presented convincing evidence. Hypertension and chronic kidney disease showed concordant evidence in meta-analyses of observational studies, and in some (but not all) meta-analyses of randomised controlled trials with respective intermediate or surrogate outcomes, but they were not statistically significant in Mendelian randomisation studies. Conclusion  Despite a few hundred systematic reviews, meta-analyses, and Mendelian randomisation studies exploring 136 unique health outcomes, convincing evidence of a clear role of SUA level only exists for gout and nephrolithiasis.

Honey bee colony loss continues to be an issue and no factor has been singled out as to the cause. In this study, we sought to determine whether two beekeeper-applied pesticide products, tau-fluvalinate and Fumagilin-B(®), and one agrochemical, chlorothalonil, impact the nutrient levels in honey bee workers in a natural colony environment. Treatments were performed in-hive and at three different periods (fall, spring, and summer) over the course of one year. Bees were sampled both at pre-treatment and two and four weeks post-treatment, weighed, and their protein and carbohydrate levels were determined using BCA and anthrone based biochemical assays, respectively. We report that, based on the pesticide concentrations tested, no significant negative impact of the pesticide products was observed on wet weight, protein levels, or carbohydrate levels of bees from treated colonies compared with bees from untreated control colonies.

A series of acoustic tests were conducted on the over the wing engine. These tests evaluated the fully suppressed noise levels in forward and reverse thrust operation and provided insight into the component noise sources of the engine plus the suppression achieved by various components. System noise levels using the contract specified calculation procedure indicate that the in-flight noise level on a 152 m sideline at takeoff and approach are 97.2 and 94.6 EPNdB, respectively, compared to a goal of 95.0 EPNdB. In reverse thrust, the system noise level was 106.1 PNdB compared to a goal of 100 PNdB. Baseline source noise levels agreed very well with pretest predictions. Inlet-radiated noise suppression of 14 PNdB was demonstrated with the high throat Mach number inlet at 0.79 throat Mach number.

The aim of the present study was to evaluate the persistence of anti-hepatitis B protective levels in young patients with type 1 diabetes, successfully immunised with a recombinant hepatitis B vaccine. We re-evaluated, after a 4 year follow-up, 54 patients and 70 age and sex-matched healthy subjects. Protective antibodies levels were found in 50/54 (92%) patients and in 67/70 (96%) controls. Moreover, anti-HBs levels were similar in diabetic patients and controls (means of log-titre and (sd); 1.95 (0.88) and 2.18 (0.64) patients and controls, respectively; P=0.11). No cases of clinical hepatitis were reported and all patients and controls remained HBc negative. These data demonstrate the persistence of anti-HBs levels in children, adolescents and young patients with type 1 diabetes after recombinant hepatitis B vaccine showing evidence of longterm immunogenity and protective effect.

Objective The aim of this study was to describe rates of exposure to bullying and sexual harassment in junior doctors in first- or second-year prevocational medical training (PGY1 or PGY2 respectively) positions in New South Wales (NSW) and the Australian Capital Territory (ACT), and to explore the types of actions taken in response. Methods A cross-sectional survey of junior doctors in PGY1 or PGY2 positions was undertaken in 2015 and 2016 (n=374 and 440 respectively). Thematic analysis was undertaken on free-text responses to describe the reporting process and outcomes in more depth. Results The estimated response rate was 17-20%. Results from both surveys followed almost identical trends. Most respondents in 2015 and 2016 reported being bullied (n=203 (54.3%) and 253 (57.5%) respectively), 16-19% reported sexual harassment (n=58 and 82 respectively) and 29% of females reported sexual harassment. Qualitative analysis elucidated reasons for not taking action in response to bullying and harassment, including workplace normalisation of these behaviours, fear of reprisal and lack of knowledge or confidence in the reporting process. For respondents who did take action, most reported ineffective or personally harmful outcomes when reporting to senior colleagues, including being dismissed or blamed, and an intention not to trust the process in the future. Conclusions The findings suggest that interventions targeted at the level of junior doctors to improve the culture of bullying and harassment in medicine are unlikely to be helpful. Different approaches that address the problem in a more systemic way are needed, as is further research about the effectiveness of such interventions. What is known about the topic? Bullying and sexual harassment are common workplace experiences in the medical profession. What does this paper add? Over half the junior doctors in the present study experienced bullying and nearly one-fifth experienced sexual harassment. Junior doctors are reluctant to speak out, not only for fear of reprisal, but also because they do not believe it is worth doing so. What are the implications for practitioners? The data confirm a systemic problem of bullying in NSW. Primarily focusing on interventions with junior doctors (e.g. resilience training) is unlikely to solve the problem. Different and multipronged approaches (e.g. raising awareness in senior colleagues and training bystanders to intervene) should be tried and studied.

Background A previous study has reported that low-frequency (LF) electroacupuncture (EA) influences salivary secretory immunoglobulin A (sIgA) and the autonomic nervous system (ANS). The ANS is known to control the secretion volume of sIgA; however, the effect of high-frequency (HF) EA on salivary sIgA has not been determined. We investigated whether HF EA affects salivary sIgA levels and the ANS. Method Sixteen healthy subjects were randomly classified into two groups: a control group and an EA group. After a 5 min rest, subjects in the EA group received EA at 100 Hz bilaterally at LI4 and LI11 for 15 min before resting for a further 40 min post-stimulation. Subjects in the control group rested for a total of 60 min. Measurements of the ANS and sIgA levels in both groups were made before, immediately after, 20 min after, and 40 min after rest or 15 min EA treatment. HF and LF components of heart rate variability were analysed as markers of ANS function. LF/HF ratio and HF were taken as indices of sympathetic and parasympathetic nerve activity, respectively. Salivary protein concentrations and sIgA levels were determined by Bradford protein assay and ELISA, respectively. Results LF/HF ratio was significantly increased immediately after EA. HF was significantly increased at 20 min after EA and sIgA level was significantly increased at 40 min after EA. In addition, HF and salivary sIgA level were positively correlated with each another. Conclusions HF EA exerted sequential positive effects on sympathetic nerve activity, parasympathetic nerve activity, and salivary sIgA level (immediately and after 20 and 40 min, respectively). HF EA may increase salivary sIgA levels by influencing parasympathetic nerve activity. PMID:26449884

The metabolic synthesis, release and breakdown of several known CNS neurotransmitters have been shown to follow a circadian pattern entrained to the environmental light/dark cycle. The levels of excitatory amino acid (EAA) transmitters such as glutamate, have been shown to vary with environmental lighting conditions. Kynurenic Acid (KA), an endogenous tryptophan metabolite and glutamate receptor antagonist, has been reported to have neuroprotective effects against EAA-induced excitotoxic cell damage. Changes in KA's activity within the mammalian basal ganglia has been proposed as being contributory to neurotoxicity in Huntington's Disease. It is not known whether CNS KA levels follow a circadian pattern or exhibit light-induced fluctuations. However, because the symptoms of certain degenerative motor disorders seem to fluctuate with daily 24 hour rhythm, we initiated studies to determine if basal ganglia KA were influenced by the daily light/dark cycle and could influence motor function. Therefore in this study, HPLC-EC was utilized to determine if basal ganglia KA levels in tissue extracts from adult male Long-Evans rats (200-250g) entrained to 24 and 48 hours constant light and dark conditions, respectively. Samples were taken one hour before the onset of the subjective day and one hour prior to the onset of the subjective night in order to detect possible phase differences in KA levels and to allow for accumulation of factors expressed in association with the light or dark phase. Data analysis revealed that KA levels in the basal ganglia vary with environmental lighting conditions; being elevated generally during the dark. Circadian phase differences in KA levels were also evident during the subjective night and subjective day, respectively. Results from these studies are discussed with respect to potential cyclic changes in neuronal susceptibility to excitotoxic damage during the daily 24 hour cycle and its possible relevance to future therapeutic approaches in treating neurodegenerative disorders.

Emerging evidence suggests that mildly down-regulated thyroid function in older persons may protect and/or reflect maintained health. Using observational data collected between January 2006 and March 2014 on a volunteer sample of 602 men and women aged 68-97 years with normal thyroid function participating in the Baltimore Longitudinal Study of Aging, this study examines the concurrent relationship between reported walking ability, usual and rapid gait speed, endurance walk performance, fatigability, and reported energy level with respect to free thyroxine (FT4) within the normal range (0.76-1.50ng/dL) as a continuous variable and categorized as low (lower quartile), medium (interquartile), or high (upper quartile). Adjusting for sex, age, race, height, weight, exercise and smoking, reported walking ability, usual and rapid gait speed, 400-m time, fatigability, and reported energy level were less favorable with increasing FT4 (p = .013 to <.001). In sex-strata, similar associations were observed except for walking ability in men and energy level in women. Categorical analyses revealed that persons with low FT4 exhibited better functional mobility, fitness, and reported energy than persons with intermediate or high levels (p < .05 for all). Persons with high-normal versus medium FT4 had slower usual and rapid gait speed (p < .05) only. Older adults with low-normal FT4 exhibit better mobility, fitness, and fatigue profiles. Mildly down-regulated thyroid function appears to align with better function in old age and may serve as a biomarker of healthy longevity.

To analyze the association between parental education and offspring's mental health in a nationally representative Spanish sample, and assess the contribution of other socioeconomic factors to the association. We conducted a secondary analysis of data on 4- to 15-year-olds participating in the 2006 Spanish National Health Survey. Mental health was assessed using the parent-reported Strengths & Difficulties Questionnaire. Parents' respective educational levels were summarized in a single variable. Univariate and multivariate analyses, controlling for family-, child- and parent-related characteristics, were used to study the association. The final sample comprised 5,635 children. A strong association between parental education and parent-reported child mental health was observed among 4- to 11-year-olds, with odds ratios (ORs) increasing as parental educational level decreased. Where both parents had a sub-university level, maternal education showed a stronger association than did paternal education. Following adjustment for covariates, parental education continued to be the strongest risk factor for parent-reported child mental health problems, OR = 3.7 (95% CI 2.4-5.8) for the lowest educational level, but no association was found among 12- to 15-year-olds. Male sex, immigrant status, activity limitation, parent's poor mental health, low social support, poor family function, single-parent families, low family income and social class were associated with parent-reported child mental health problems in both age groups. Our results show that there is a strong association between parental education and parent-reported child mental health, and that this is indeed stronger than that for income and social class. Among adolescents, however, the effect of parental education would appear to be outweighed by other factors.

To determine the effect of an educational strategy promoting participation in the development of critical reading of educational research reports on professors of Educational Research and Teacher Education (CIEFD's). We performed an intervention study, multicenter professors (medical specialists) who enrolled in the courses: Diploma in teaching methodological level 1 and 2 (n = 46, n = 29, respectively) in the six CIEFD's (D.F. Siglo XXI, DF. La Raza, Nuevo León, Sonora, Puebla and Jalisco), in the period March to August 2007. A tool was built that assessed the variables critical appraisal of educational research reports, the construct validity, content and reliability was assessed by experts in education research. The educational strategy developed in the form of seminars, which were held three times a week in the Certification in teaching methodological level 1 and twice per week in the Certification Level 2 in teaching methodology duration per session: 6 h. The instrument was applied at the beginning and end of the course. In the two Graduates it was observed in the total group, an advance in the three indicators of critical reading, which was expressed with statistically significant differences; in the global score of the Diploma level 1 (final vs. initial measurement) the following mediums were observed: 36-67 (p = 0.0001); in the Diploma level 2, it was observed in its overall rating: 42-78 (p = 0.0001). This inquiry from the results observed some of theoretical approaches to mainstreaming participatory. An educational strategy promoting participation produced a breakthrough in the three indicators (to interpret, to judge and to formulate proposals) for critical reading of educational research reports.

Fitness in paradise: quality of forensic reports submitted to the Hawaii judiciary.

This paper examined quality of forensic reports submitted to the Hawaii Judiciary. Hawaii utilizes a three panel system for assessing fitness to proceed, where two psychologists and one psychiatrist submit independent reports to the Court. Utilizing a survey instrument based on previous research and nationally-derived quality standards, 150 competency to stand trial (CST) reports were examined. Reports demonstrated pervasive mediocrity with respect to quality (Mean QC=68.95, SD=15.21). One quarter (N=38) of the reports scored at or above 80% of the maximum possible score. Levels of CST agreement between evaluators and evaluators and judges were high. Report quality did not differ as a function of evaluator professional identity. Full-time employed evaluators submitted a greater number of reports above the quality criterion. For those evaluators who attended the March training, reports demonstrated significantly improved quality. Suggestions for enhancing report quality are offered with a special attention to inclusion of report elements, focus on inclusion of historical elements, and clearly described rationales supporting forensic opinions.

The aim was to examine the prevalence of mental health difficulties and prejudices toward mental illness among adolescents, and to analyze possible school and school class effects on these issues. The sample comprised 4,046 pupils (16-19 years) in 257 school classes from 45 Norwegian upper secondary schools. The estimated response rate among the pupils was about 96%. Self-reported mental health difficulties were measured with a four-item scale that covered emotional and behavioral difficulties. Prejudiced attitudes toward mental illness were assessed using a nine-item scale. Multilevel regression analysis was used to estimate the contribution of factors at the individual level, and at the school and class levels. Most of the variance in self-reported mental health difficulties and prejudices was accounted for by individual level factors (92-94%). However, there were statistically significant school and class level effects (P < 0.01), confounded by socioeconomic factors. Mental health difficulties were commonly reported, more often by females than males (P < 0.01). Difficulties with emotions and attention were the two main problem areas, with definite to severe difficulties being reported by 19 and 21% of the females, and by 9 and 16% of the males, respectively. Prejudices were reported more often by males than females (P < 0.01). Both self-reported mental health difficulties and prejudiced attitudes were related to educational program, living situation, and parental education (P < 0.01). The relatively high prevalences of mental health difficulties and prejudiced attitudes toward mental illness among adolescents indicate a need for effective mental health intervention programs. Targeted intervention strategies should be considered when there is evidence of a high number of risk factors in schools and school classes. Furthermore, the gender differences found in self-reported mental health difficulties and prejudices suggest a need for gender-differentiated programs.

The subjects were 22 patients with severe head injury. The average age was 45 +/- 18.3 years. There were 13 survivors and 9 fatalities. Samples of peripheral blood and cerebrospinal fluid (CSF) were taken four times, at the time of admission and at 24, 72, and 168 hours later. IL-6: For the survivor group, peripheral blood levels were 181, 105, 37, and 26 pg/ml, respectively (median values). CSF levels were 5376, 3565, 328, and 764 pg/ml, respectively. For the fatality group, peripheral blood levels were 102, 176, 873, and 3059 pg/ml, respectively, whereas CSF levels were 15241, 97384, 548225, and 366500 pg/ml, respectively. IL-8: For the survivor group, peripheral blood levels were 36, 15, 15, and 15 pg/ml, respectively, whereas CSF levels were 23736, 4074, 355, and 1509 pg/ml, respectively. For the fatality group, peripheral blood levels were 21, 28, 43, and 77 pg/mL, respectively, whereas CSF levels were 29003, 8906, 5852, and 8220 pg/ml, respectively. IL-6 and IL-8 levels were significantly higher after 72 hours in the fatality group. The fact that CSF IL-8 was 1000 times that in the peripheral blood at the time of admission, and decreased thereafter, indicates that IL-8 is a key mediator of neuroinflammation.

To study the self-reported level of physical activity (PA) and quality of life (QOL) in patients receiving physical activity on prescription (PAP) for up to 24 months. Observational study conducted in a regular healthcare setting. A primary care population in Sweden receiving physical activity on prescription as part of regular care was studied alongside a reference group. The group comprised 146 patients receiving PAP at two different primary care locations (n = 96 and 50, respectively). The reference group comprised 58 patients recruited from two different primary care centres in the same region. We used two self-report questionnaires - the four-level Saltin-Grimby Physical Activity Level Scale (SGPALS) to assess physical activity, and SF-36 to assess QOL. A significant increase in the PA level was found at six and 12 months following PAP, with an ongoing non-significant trend at 24 months (p = .09). A clear improvement in QOL was seen during the period. At 24 months, significant and clinically relevant improvements in QOL persisted in four out of eight sub-scale scores (Physical Role Limitation, Bodily Pain, General Health,Vitality) and in one out of two summary scores (Physical Component Summary). Patients receiving PAP showed an increased level of self-reported PA at six and 12 months and improved QOL for up to 24 months in several domains. The Swedish PAP method seems to be a feasible method for bringing about changes in physical activity in different patient populations in regular primary healthcare. While increased physical activity (PA) is shown to improve health, the implementation of methods designed to increase activity is still being developed. Key points The present study confirms that the Swedish physical activity on prescription (PAP) method increases the self-reported level of PA in the primary care setting at six and 12 months. Furthermore, this study shows that PAP recipients report a clinically relevant long-term improvement in quality of life, persisting for two years post-prescription, thus extending earlier findings. These findings have clinical implications for the implementation of PAP in healthcare.

To determine the perception of Primary Care (PC) physicians on the integration with cardiology (CA) through continuity of healthcare programs. A cross-sectional and multicentre study was conducted, in which a total of 200 PC physicians from all over Spain completed a qualitative survey that evaluated the level of integration with CA in secondary prevention. Physicians were grouped according to the level of PC-CA integration. The integration between CA and PC was good, but it was better in those centres with a higher integration (74.0% vs. 60.0%; p=.02) and in general, physicians considered that integration had improved (92.0% vs. 73.0%; p<.001). Almost all PC physicians received the hospital discharge report. The majority of the hospital discharge reports included recommendations about the CA and PC follow-up, control of risk factors, as well as the duration of secondary prevention treatment, with not significant differences according to the level of integration. In 55.8%, 63.6%, and 51.3% of hospital discharge reports, indications were given on when to perform the follow-up blood analysis, as well as information about returning to working life and sexual activity, respectively. The most common communication method was the paper-based report (75 vs. 84%; p=NS). The communication between healthcare levels was greater in those Primary Care centres with a higher level of integration, as well as periodicity of the communication and the satisfaction of physicians (80.0% vs. 63.0%; p=.005). The level of integration between PC and CA is, in general, satisfactory, but those centres with a higher level of integration benefit more from a greater communication and satisfaction.

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.

Growth hormone (GH) supplementation may help to preserve erectile function. We assessed whether serum insulin-like growth factor 1 (IGF-1) levels, a surrogate for GH levels, correlate with sexual function scores in 65 men who completed the Sexual Health Inventory for Men (SHIM) and Expanded Prostate Cancer Index Composite (EPIC) questionnaires, and had serum IGF-1 and testosterone levels determined. Median±s.d. IGF-1 level, SHIM and EPIC scores were 235.0±86.4, 19.5±8.7 and 56.4±28.3 mg ml(-1), respectively. IGF-1 levels and total SHIM score correlate significantly (r=0.31, P=0.02), as do IGF-1 levels and all individual SHIM question scores, and IGF-1 levels and the sexual domain of the EPIC questionnaire (r=0.30, P=0.02). No correlation was observed between IGF-1 levels and Gleason score, IGF-1 and testosterone level or SHIM score and testosterone level. These data support a potential role for the GH axis in erectile function.

Measurement of human pancreatic polypeptide may be useful for assessment of gastrointestinal function, integrity of the parasympathetic nervous system or screening for endocrine neoplasia. In adults hPP levels have been reported to increase with age. However hPP levels throughout childhood have not been well characterized in comparison with the adult range. We studied fasting human pancreatic polypeptide (hPP) from 45 pediatric patients, from infancy - 15 years, and 18 older adolescents and adults aged 16-45 years. The mean hPP level of children (233 +/- 147 pg/ml) was significantly higher than that (113 +/- 35 pg/ml) of adults (P less than .0001). There was no difference in mean hPP levels of children with normal growth hormone secretion compared to growth hormone deficient patients. There was no effect of gender or body mass index on hPP levels. We conclude that fasting hPP levels must be interpreted with respect to the age of the subject, children particularly, in that preteens may have higher fasting levels than older teenagers and adults.

Conflicts over treatment decisions have been linked to physicians' emotional states. To measure the prevalence of emotional exhaustion and conflicts over treatment decisions among US obstetrician/gynaecologists (ob/gyns), and to examine the relationship between the two and the physician characteristics that predict each. Mailed survey of a stratified random sample of 1800 US ob/gyn physicians. Criterion variables were levels of emotional exhaustion and frequency of conflict with colleagues and patients. Predictors included physicians' religious characteristics and self-perceived empathy. Response rate among eligible physicians was 66% (1154/1760). 36% of ob/gyns reported high levels of emotional exhaustion, and majorities reported conflict with colleagues (59%) and patients (61%). Those reporting conflict were much more likely to report emotional exhaustion (58% vs 29% who never conflict, OR, 95% CI 2.8, 1.6 to 4.8 for conflict with colleagues; 55% versus 26%, OR, 95% CI 2.2, 1.4 to 3.5 for conflict with patients). Physicians with lower self-perceived empathy were more likely to report physician-patient conflicts (65% vs 58% with higher empathy, OR, 95% CI 1.4, 1.0 to 1.9), as were female ob/gyns (66% vs 57% of males, OR, 95% CI 1.5, 1.1 to 2.0). Foreign-born physicians were less likely to report such conflicts (47% vs 64% of US born, OR, 95% CI 0.5, 0.4 to 0.8). Physicians' religious characteristics were not significantly associated with reporting conflict. Conflicts over treatment decisions are associated with physicians' empathy, gender, immigration history and level of emotional exhaustion. With respect to the latter, conflict in the clinical encounter may represent an overlooked source or sign of burnout among ob/gyns.

This case report concerns a 23-year-old woman with chronic periodontitis who had been previously diagnosed with Takayasu arteritis (TA). Her erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level were decreased before and 3 months after non-surgical periodontal therapy with no change in her prescribed medications (ESR from 31.00 mm/h to 23.0 mm/h, CRP from 21.40 mg/L to 18.46 mm/h). Through the occasional findings, we raised a hypothetical analysis about the potential relationship between periodontitis and TA with respect to inflammatory factors, bacteria and medication. Further studies of large samples are needed to verify the findings.

Gene therapy involves the safe and effective delivery of one or more genes of interest to target cells in vivo. The advantages of using nonviral delivery systems include ease of preparation, low toxicity, and weak immunogenicity. Nonviral delivery methods, when combined with a noninvasive, clinically applicable imaging assay, will greatly aid in the optimization of gene therapy approaches for cancer. We demonstrate cationic lipid-mediated noninvasive monitoring of reporter gene expression of firefly (Photinus pyralis) luciferase (fl) and a mutant herpes simplex virus type I thymidine kinase (HSV1-sr39tk, tk) in living mice using a cooled charge coupled device (CCD) camera and positron emission tomography (PET), respectively. We observe a high level of fl and tk reporter gene expression predominantly in the lungs after a single injection of the extruded DOTAP:cholesterol DNA liposome complexes by way of the tail vein, seen to be time- and dose-dependent. We observe a good correlation between the in vivo bioluminescent signal and the ex vivo firefly luciferase enzyme (FL) activity in different organs. We further demonstrate the feasibility of noninvasively imaging both optical and PET reporter gene expression in the same animal using the CCD camera and microPET, respectively.

Energy balance-related behavior on schooldays and beliefs about school-based interventions may differ between students in different educational levels, sexes, and BMI (body mass index) categories. In Zwolle (the Netherlands), 1,084 adolescents (13-15 years) at 9 secondary schools completed a questionnaire. Overweight prevalence (boys 18.1%, girls 19.3%) increased with decreasing educational level, especially in boys. Girls reported healthier behavior than boys regarding daily consumption of fruit (35% vs. 29%), vegetables (58% vs. 48%), ≤1 snack/candy (36% vs. 26%), ≤3 glasses of sugared drinks (80% vs. 73%; all p < .05). Unhealthier dietary behaviors were associated with lower educational level, except for eating sugary and savory snacks. Snacks and sugared drinks consumed at school were mostly brought from home (61.6% and 68.5%, respectively). Overweight students reported less frequent consumption of daily breakfast, snacks, and sugared drinks than nonoverweight students. Of all students, 40% spent ≥1 hour per day cycling to school. Lower educational level students reported less organized sports activities than higher level students, but more outside play and other activities. Overweight was associated with cycling to school (boys) and participating in organized sports (girls). More girls than boys were interested in lessons about healthy nutrition (44.4% vs. 31.7%). To stimulate physical activity, boys suggested more physical education classes (63%), girls advised more variation (47%) and choice (43%). A healthy school canteen (57%) and offering free fruit (67%) were suggested as promising interventions to stimulate healthy behavior. Educational and environmental interventions to tackle unhealthy dietary and physical activity behavior should be developed in collaboration with parents and tailored to educational level and gender.

Distinguishing between relational and physical aggression has become a key feature of many developmental studies in North America and Western Europe, but very little information is available on relational aggression in more diverse cultural contexts. This study examined the factor structure of, gender differences in, and associations between relational and physical aggression in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Children ages 7 to 10 years (N = 1410) reported on their relationally and physically aggressive behavior. Relational and physical aggression shared a common factor structure across countries. Unsurprisingly, boys reported being more physically aggressive than girls across all nine countries; surprisingly, there were no significant gender differences in relational aggression. In all nine countries, relational and physical aggression were significantly correlated (average r = .49). The countries differed significantly in the mean levels of both relational and physical aggression that children reported using and with respect to whether children reported using more physical than relational aggression or more relational than physical aggression. Despite mean level differences in relational and physical aggression across countries, the findings provided support for cross-country similarities in associations between relational and physical aggression, as well as links between gender and aggression.

This study examined presenting concerns and characteristics of emerging adults (EAs) seeking treatment at an early intervention program for mood and anxiety disorders to better understand presenting concerns when treatment is needed. During an intake assessment conducted by a social worker or clinical psychologist, participants (N = 548; 62% female, 38% male) reported their top three current life concerns, which were analyzed qualitatively using thematic analysis. Participants completed a battery of questionnaires assessing demographic information, symptomatology, and daily functioning. Females presented with significantly higher levels of anxiety, and both females and younger individuals (age 16-18) presented with significantly higher levels of depression compared to males and older individuals (age 19-26), respectively. The two most commonly reported presenting concerns were problems in interpersonal relationships and academics, and females were more likely to report academic concerns than males. The majority of participants reported seeking help for a wide range of problems commonly faced by EAs (83.7%), and participants rarely expressed concerns about particular symptoms of mood and/or anxiety disorders (16.3%). EAs and those supporting EAs may benefit from learning when psychosocial concerns are indicative of mental health challenges warranting professional attention.

Beliefs about the causes of events have implications for emotional reactions, distress, expectations for the future, and behavioral responses. In this article we report on two issues: the organizational context that contributes to nursing aide (NA) assault and reporting, and serendipitous findings that arose from investigating unexpected response rates to a survey. Data were collected in 11 rural nursing homes using a structured prospective event-reporting diary to collect detailed information about incidents of physical aggression, followed by focus groups to further explore NAs' perceptions of these events. Here we report on analysis of 19 focus groups conducted with 138 NAs. Participants described organizational-level factors that constrained their practice, affected their interactions with residents, and created a context that put them at risk for physical assault. These factors also affected their willingness to provide written documentation about aggressive incidents. The key issues were frustration at being blamed for causing aggression, lack of action to address the problem, and a desire for respect and involvement in decision making. Organizational changes are needed to modify the contextual factors contributing to assault risk. Researchers must be willing to modify study designs to more fully understand the nature of the problem studied.

Evidence-based guidelines for monitoring of serum phosphate levels and for the treatment of hypophosphataemia in critically ill patients are lacking. The aim of this survey was to evaluate current practice with respect to diagnosis and treatment of hypophosphataemia in critically ill patients among intensive care unit (ICU) physicians in the Netherlands. A survey was conducted among all hospitals with an ICU in the Netherlands. Paediatric ICUs were excluded from participation. A questionnaire was sent, with questions on practice regarding serum phosphate monitoring and treatment of hypophosphataemia. Respondents returned the questionnaire either by mail or through a web-based survey. A response was received from 67÷89 ICUs (75%). Respondents mentioned renal replacement therapy, sepsis and malnutrition, as well as surgery involving cardiopulmonary bypass as the most important causes of hypophosphataemia in intensive care unit patients. Of all respondents, 46% reported to measure serum phosphate levels on a daily basis, whereas in 12% serum phosphate levels were measured only on clinical indication. Less than half of the respondents had some sort of guideline for correction of hypophosphataemia. In a vast majority (79%), correction of hypophosphataemia was reported to start with serum phosphate levels.

We have conducted longitudinal studies focused on the expression profiles of signaling pathways and gene networks in children with septic shock. Genome-level expression profiles were generated from whole blood-derived RNA of children with septic shock (n = 30) corresponding to day one and day three of septic shock, respectively. Based on sequential statistical and expression filters, day one and day three of septic shock were characterized by differential regulation of 2,142 and 2,504 gene probes, respectively, relative to controls (n = 15). Venn analysis demonstrated 239 unique genes in the day one dataset, 598 unique genes in the day three dataset, and 1,906 genes common to both datasets. Functional analyses demonstrated time-dependent, differential regulation of genes involved in multiple signaling pathways and gene networks primarily related to immunity and inflammation. Notably, multiple and distinct gene networks involving T cell- and MHC antigen-related biology were persistently downregulated on both day one and day three. Further analyses demonstrated large scale, persistent downregulation of genes corresponding to functional annotations related to zinc homeostasis. These data represent the largest reported cohort of patients with septic shock subjected to longitudinal genome-level expression profiling. The data further advance our genome-level understanding of pediatric septic shock and support novel hypotheses. PMID:17932561

This cross-sectional survey aimed to evaluate the prevalence of burnout and estimated psychiatric disorders among haemato-oncology healthcare professionals in Italy. The aspects of work that respondents perceive as stressful and satisfying have also been examined. The assessments were made using the Maslach Burnout Inventory (MBI), General Health Questionnaire and a study-specific questionnaire. Logistic regression models were applied to show associations between different sources of work-related stress and burnout. Three hundred and eighty-seven out of 440 (87.95%) returned their questionnaires. The scores on MBI subscales indicate a high level of emotional exhaustion in 32.2% of the physicians and 31.9% of the nurses; a high level of Depersonalisation in 29.8 and 23.6%, respectively; and a low level of personal accomplishment in 12.4 and 15.3% respectively. The estimated prevalence of psychiatric disorders was 36.4% in physicians and 28.8% in nurses. Statistical analysis confirmed age, sex, personal dissatisfaction, physical tiredness and working with demanding patients to be associated with burnout. In conclusion, haemato-oncology healthcare professionals report a level of burnout and estimated psychiatric morbidity comparable to other oncological areas. Knowledge of the mechanisms of burnout and preventing and dealing with them is therefore a fundamental requirement for the improvement of quality in health services and job satisfaction.

In this study, acrylamide exposure from selected cereal-based baby food samples was investigated among toddlers aged 1-3 years in Turkey. The study contained three steps. The first step was collecting food consumption data and toddlers' physical properties, such as gender, age and body weight, using a questionnaire given to parents by a trained interviewer between January and March 2012. The second step was determining the acrylamide levels in food samples that were reported on by the parents in the questionnaire, using a gas chromatography-mass spectrometry (GC-MS) method. The last step was combining the determined acrylamide levels in selected food samples with individual food consumption and body weight data using a deterministic approach to estimate the acrylamide exposure levels. The mean acrylamide levels of baby biscuits, breads, baby bread-rusks, crackers, biscuits, breakfast cereals and powdered cereal-based baby foods were 153, 225, 121, 604, 495, 290 and 36 μg/kg, respectively. The minimum, mean and maximum acrylamide exposures were estimated to be 0.06, 1.43 and 6.41 μg/kg BW per day, respectively. The foods that contributed to acrylamide exposure were aligned from high to low as bread, crackers, biscuits, baby biscuits, powdered cereal-based baby foods, baby bread-rusks and breakfast cereals.

The bilateral and unilateral interlaminar techniques for bilateral decompression both demonstrate good results for the treatment of degenerative lumbar spinal stenosis (DLSS). Although there is some discussion about which approach is more effective, studies that directly compare these two popular techniques are rare. To address this shortcoming, this study compares postoperative functional disability, pain, and patient satisfaction among patients with single-level DLSS who underwent bilateral decompression using either a bilateral or unilateral approach. This retrospective study included patients who underwent operations between November 1, 2009, and October 1, 2011. These patients underwent single-level bilateral decompressive surgery using either the bilateral or unilateral interlaminar approach at one of 5 participating hospitals. Exclusion criteria included previous lumbar surgery, additional disc surgery, and spondylolisthesis requiring fusion surgery. Primary outcome measures included bodily pain (as reported using the visual analog scale [VAS]), the Roland-Morris Disability Questionnaire (RMDQ), and the Oswestry Disability Index (ODI). In addition, reductions in leg and back symptoms and the patient's general evaluation of the procedure were queried. Finally, patient satisfaction and surgical parameters were evaluated. Questionnaires were sent to each patient's home, and electronic patient files were used to collect the data. One hundred and seventy-five patients returned the questionnaire (74.4% response rate; 68 and 107 patients who underwent the bilateral or unilateral approach, respectively). Mean age at surgery was 68 years (range 34-89 years), and the mean follow-up period was 14.2 months (range 3.3-27.4 years). There were no significant differences in ODI (20.3 vs 22.6 for the bilateral and unilateral approaches, respectively), RMDQ (3.99 vs 4.8, respectively), or pain scores between treatment groups. Back symptoms were reduced in 74.8% (bilateral: 74.6% vs unilateral: 75%; not significant), and leg symptoms in 80.6% of the patients (bilateral: 73.1% vs unilateral: 85.4%; p = 0.048). In total, 72.1% (bilateral) and 80.0% (unilateral) of patients reported good overall treatment results (p = 0.226). Significantly more patients in the unilateral group reported a better overall satisfaction with the procedure (82.1% vs 69.1%; p = 0.047). There were no differences in postoperative functional disability and pain between the surgical techniques. The significant differences in patient satisfaction and reduction in leg symptoms were unrelated to surgical technique. The overall treatment results were satisfactory. Both techniques are safe and effective options for treating patients with single-level DLSS.

Collaborative testing for key-term definitions under representative conditions: Efficiency costs and no learning benefits.

PubMed

2018-01-01

Students are expected to learn key-term definitions across many different grade levels and academic disciplines. Thus, investigating ways to promote understanding of key-term definitions is of critical importance for applied purposes. A recent survey showed that learners report engaging in collaborative practice testing when learning key-term definitions, with outcomes also shedding light on the way in which learners report engaging in collaborative testing in real-world contexts (Wissman & Rawson, 2016, Memory, 24, 223-239). However, no research has directly explored the effectiveness of engaging in collaborative testing under representative conditions. Accordingly, the current research evaluates the costs (with respect to efficiency) and the benefits (with respect to learning) of collaborative testing for key-term definitions under representative conditions. In three experiments (ns = 94, 74, 95), learners individually studied key-term definitions and then completed retrieval practice, which occurred either individually or collaboratively (in dyads). Two days later, all learners completed a final individual test. Results from Experiments 1-2 showed a cost (with respect to efficiency) and no benefit (with respect to learning) of engaging in collaborative testing for key-term definitions. Experiment 3 evaluated a theoretical explanation for why collaborative benefits do not emerge under representative conditions. Collectively, outcomes indicate that collaborative testing versus individual testing is less effective and less efficient when learning key-term definitions under representative conditions.

Excited states of negative aluminum ion are reviewed, and calculations of electron affinities of the states (3s^23p^2)^1D and (3s3p^3){^5}{S}° relative to the (3s^23p)^2P° and (3s3p^2)^4P respectively of the neutral aluminum atom are reported in the framework of nonrelativistic configuration interaction (CI) method. A priori selected CI (SCI) with truncation energy error (Bunge in J Chem Phys 125:014107, 2006) and CI by parts (Bunge and Carbó-Dorca in J Chem Phys 125:014108, 2006) are used to approximate the valence nonrelativistic energy. Systematic studies of convergence of electron affinity with respect to the CI excitation level are reported. The calculated value of the electron affinity for ^1D state is 78.675(3) meV. Detailed Calculations on the ^5S°c state reveals that is 1216.8166(3) meV below the ^4P state.

The energy requirements in free-living elderly rural people were investigated by measuring physical activity level and basal energy expenditure using a physical activity questionnaire and indirect calorimetry, respectively. Approximately 65 different occupational and leisure activities over the previous 12 months were considered. Energy expenditure by physical activity was estimated using PAL for specific activities reported in the literature. All 65 the activities were considered to adapt the questionnaire. Reproducibility was evaluated by administering the questionnaire on two separate occasions within 3-4 week elapsed between them. It was found to be reliable for the study (Pearson correlation was r = 0.85; p < 0.05). The physical activity level of the women and men were 1.50 +/- 0.29 and 1.65 +/- 0.66, respectively (p < 0.05). The basal metabolic rate also differed between women and men (p < 0.05) with 5348 +/- 719 kJ/day and 6160 +/- 862 kJ/day, respectively. Similarly the total energy expenditure was different (p < 0.05) in women and men 8311 +/- 1610 kJ/day and 10,210 +/- 2268 kJ/day, respectively. Results indicate that the physical activity questionnaire presented can be an alternative methodology to estimate physical activity in free-living elderly people and together with indirect calorimetry measurements can be useful to estimate their energy expenditure and hence energy requirements.

Prevalence of extravertebral cement leakage after vertebroplasty: procedural documentation versus CT detection.

Reported incidence of extravertebral cement leakage after vertebroplasty varies widely across studies. To retrospectively compare the relative detection rates of extravertebral leakage noted under intra-procedural fluoroscopic surveillance, postprocedure plain radiographs, and postprocedure computed tomography (CT) in a cohort of patients undergoing vertebroplasty. With IRB approval, we retrospectively identified 181 patients with 277 levels treated with percutaneous vertebroplasty among a total of 1255 patients undergoing vertebroplasty between 1999 and 2010 who had subsequently undergone a CT examination that included the treated level(s). Categories of leakage were paravertebral, end plate, epidural, and prevertebral venous leakage. CT-detected leak rates were then compared to those noted on the vertebroplasty procedure reports and the archived fluoroscopic images for this same cohort using Pearson's χ(2) test. One hundred and forty-nine (82%, 95% CI 76-87%) of 181 patients demonstrated evidence of some type of leakage on CT at one or more treated levels. Sixty-two (34%, 95% CI 28-42%) and seventy-seven (50%, 95% CI 43-57%) of 149 CT-detected leaks were reported in the procedural dictation or detected on plain radiography (P = 0.01 and 0.006, respectively). The most common type of leakage noted on CT was end plate (n = 81, 45%, 95% CI 38-52%), followed by paravertebral (n = 64, 35%, 95% CI 29-43%), epidural (n = 36, 20%, 95% CI 15-26%), and prevertebral venous (n = 32, 18%, 95% CI 13-24%). Cement leakage after vertebroplasty is common and is often not reported by operators in procedural dictations. CT detects substantially more leaks than plain radiography.

Appropriate treatment of hypothyroidism requires accurate diagnosis. This registry aimed to study the disease profile and treatment paradigm in hypothyroid patients in India. We registered 1500 newly diagnosed, treatment-naïve, adult hypothyroid males and nonpregnant females across 33 centers and collected relevant data from medical records. The first analysis report on baseline data is presented here. The mean age of the study population was 41.1 ± 14.01 years with a female to male ratio of 7:3. The most frequently reported symptoms and signs were fatigue (60.17%) and weight gain with poor appetite (36.22%). Menstrual abnormalities were reported in all women ( n = 730) who had not attained menopause. Grades 1 and 2 goiter (as per the WHO) were observed in 15.41% and 3.27% patients, respectively. Comorbidities were reported in 545 patients (36.36%), type 2 diabetes mellitus being the most prevalent (13.54%) followed by hypertension (11.34%). Total serum thyroxine (T4) and thyroid-stimulating hormone (TSH) levels were assessed in 291 (19.47%) patients only. In majority of patients (81%), treatment was based on serum TSH levels alone. The dose of levothyroxine ranged from 12.5 to 375 mcg. Guidelines suggest a diagnosis of hypothyroidism based on TSH and T4 levels. However, most of the patients as observed in this registry received treatment with levothyroxine based on TSH levels alone, thus highlighting the need for awareness and scientific education among clinicians in India. The use of standard doses (100, 75, and 25 mcg) of levothyroxine may point toward empirical management practices.

The aim of this study was to assess the feasibility of using questionnaires and accelerometers to measure physical activity and sedentary behavior among inpatient adults with mental illness. Participants completed a physical activity and sitting time questionnaire and wore an accelerometer for 7 consecutive days. Feasibility was assessed in terms of participant engagement, self-reported ease/ difficulty of completing study components, extreme self-report data values and adherence to accelerometer wear time criteria. Ease/difficulty ratings were examined by level of distress. 177 inpatients were invited to the study, 101 completed the questionnaires and 36 provided valid accelerometry data. Participants found it more difficult to complete sitting time and physical activity questionnaires than to wear the accelerometer during waking hours (z = 3.787, P < .001; z = 2.824, P = .005 respectively). No significant differences were found in ease/ difficulty ratings by level of distress for any of the study components. Extreme values for self-reported sitting time were identified in 27% of participants. Inpatient adults with mental illness can engage with self-report and objective methods of measuring physical activity and sedentary behavior. They were initially less willing to participate in objective measurement, which may however be more feasible than self-report measures.

Nickel-63 microirradiators.

Steeb, Jennifer; Josowicz, Mira; Janata, Jiri

2009-03-01

Here we report the fabrication of two types of microirradiators, consisting of a recessed disk and protruding wire with low-beta-energy radionuclide Ni-63 electrodeposited onto a 25 microm diameter Pt wire. Ni-63 is constricted to a small surface area of the microelectrode; hence, this tool provides a means of delivery of localized, large dose density of beta radiation to the object but a minimal dose exposure to the user. The activity levels of Ni-63 emitted from the recessed disk and protruding wire are 0.25 and 1 Bq, respectively. The corresponding beta particles flux levels emitted from the recessed disk and protruding wire are 51 and 11 kBq/cm(2), respectively. These values, measured experimentally using liquid scintillation counting, fit very well the expected values of activity for each microirradiator, calculated considering the self-absorption effect, typical for low-energy beta particles. In order to determine the optimal configuration the dose rates for varying distances from the object were calculated.

Locus of control and utilization of social support among mothers of young children with physical disabilities.

Sixty mothers of young children with physical disabilities were studied with respect to the effect of the mothers' locus of control on the utilization of social support. The initial findings failed to support the thesis that mothers with an 'internally' focused locus of control would demonstrate greater utilization of their support system, both in terms of descriptive and functional measures. A secondary analysis showed that the mothers' age, the children's level of functioning, and the existence of additional members of the family with a disability served as intervening variables. Only among older mothers, who perceived their children's functioning as severe, was there significant association between the locus of control ('internal') and greater use of their social support system. 'Internal' mothers who had no additional extended family members with a disability reported higher levels of functional social support, as compared to 'external' mothers. Findings are interpreted with respect to social support theory and its implications to applied research.

Fibromyalgia syndrome (FMS) is a chronic, idiopathic condition of widespread musculoskeletal pain affecting more women than men. Even though clinical studies have provided evidence of altered central pain pathways, the lack of definitive pathogenesis or reliable objective markers has hampered development of effective treatments. Here we report that the neuropeptides corticotropin-releasing hormone (CRH), substance P (SP), and SP-structurally-related hemokinin-1 (HK-1) were significantly (P = 0.026, P < 0.0001, and P = 0.002, respectively) elevated (0.82 ± 0.57 ng/ml, 0.39 ± 0.18 ng/ml, and 7.98 ± 3.12 ng/ml, respectively) in the serum of patients with FMS compared with healthy controls (0.49 ± 0.26 ng/ml, 0.12 ± 0.1 ng/ml, and 5.71 ± 1.08 ng/ml, respectively). Moreover, SP and HK-1 levels were positively correlated (Pearson r = 0.45, P = 0.002) in FMS. The serum concentrations of the inflammatory cytokines interleukin (IL)-6 and tumor necrosis factor (TNF) were also significantly (P = 0.029 and P = 0.006, respectively) higher (2.97 ± 2.35 pg/ml and 0.92 ± 0.31 pg/ml, respectively) in the FMS group compared with healthy subjects (1.79 ± 0.62 pg/ml and 0.69 ± 0.16 pg/ml, respectively). In contrast, serum IL-31 and IL-33 levels were significantly lower (P = 0.0001 and P = 0.044, respectively) in the FMS patients (849.5 ± 1005 pg/ml and 923.2 ± 1284 pg/ml, respectively) in comparison with healthy controls (1281 ± 806.4 pg/ml and 3149 ± 4073 pg/ml, respectively). FMS serum levels of neurotensin were not different from controls. We had previously shown that CRH and SP stimulate IL-6 and TNF release from mast cells (MCs). Our current results indicate that neuropeptides could stimulate MCs to secrete inflammatory cytokines that contribute importantly to the symptoms of FMS. Treatment directed at preventing the secretion or antagonizing these elevated neuroimmune markers, both centrally and peripherally, may prove to be useful in the management of FMS. PMID:26763911

Determine levels of agreement among intensive care unit patients and their family members, nurses, and physicians (proxies) regarding patients' symptoms and compare levels of mean intensity (i.e., the magnitude of a symptom sensation) and distress (i.e., the degree of emotionality that a symptom engenders) of symptoms among patients and proxy reporters. Prospective study of proxy reporters of symptoms in seriously ill patients. Two intensive care units in a tertiary medical center in the Western United States. Two hundred and forty-five intensive care unit patients, 243 family members, 103 nurses, and 92 physicians. None. On the basis of the magnitude of intraclass correlation coefficients, where coefficients from .35 to .78 are considered to be appropriately robust, correlation coefficients between patients' and family members' ratings met this criterion (≥.35) for intensity in six of ten symptoms. No intensity ratings between patients and nurses had intraclass correlation coefficients >.32. Three symptoms had intensity correlation coefficients of ≥.36 between patients' and physicians' ratings. Correlation coefficients between patients and family members were >.40 for five symptom-distress ratings. No symptoms had distress correlation coefficients of ≥.28 between patients' and nurses' ratings. Two symptoms had symptom-distress correlation coefficients between patients' and physicians' ratings at >.39. Family members, nurses, and physicians reported higher symptom-intensity scores than patients did for 80%, 60%, and 60% of the symptoms, respectively. Family members, nurses, and physicians reported higher symptom-distress scores than patients did for 90%, 70%, and 80% of the symptoms, respectively. Patient-family intraclass correlation coefficients were sufficiently close for us to consider using family members to help assess intensive care unit patients' symptoms. Relatively low intraclass correlation coefficients between intensive care unit clinicians' and patients' symptom ratings indicate that some proxy raters overestimate whereas others underestimate patients' symptoms. Proxy overestimation of patients' symptom scores warrants further study because this may influence decisions about treating patients' symptoms.

This study evaluated the potential risk to hearing associated with the use of portable digital audio players. Twenty-eight university students (12 males, 16 females; aged 17-23) completed a 49-item questionnaire assessing user listening habits and subjective measures of hearing health. Sound level measurements of participants' self-identified typical and 'worst case' volume levels were taken in different classrooms with background sound levels between 43 and 52 dBA. The median frequency and duration of use was 2 h per day, 6.5 days a week. The median sound levels and interquartile ranges (IQR) at typical and 'worst case' volume settings were 71 dBA (IQR=12) and 79 dBA (IQR=9), respectively. When typical sound levels were considered with self-reported duration of daily use, none of the participants surpassed Leq(8) 85 dBA. On the questionnaire, 19 students reported experiencing at least one symptom of possible noise-induced hearing loss. Significant differences in MP3 user listening patterns were found between respondents who had experienced tinnitus and those who had not. The findings add to a growing body of literature that collectively supports a need for further research investigating MP3 player user listening habits in order to assess their potential risk to hearing health.

State reports published by the Utah Department of Health (2005) and the Utah Department of Water Quality (2008) determined that there were elevated levels of PCBs (Polychlorinated biphenyls) that exceeded the EPA's cancer (0.02 𝑚𝑔 𝑘𝑔-1) and non-cancer screening levels (0.08 𝑚𝑔 𝑘𝑔-1) in two fish species from Utah Lake, the Common Carp (Cyprinus carpio) and the Channel Catfish (Ictalurus punctatus). Fish consumption advisories were issued for both of these fish species due to their health effects of PCBs. The Common Carp is a non-native predatory species that comprise 90% of the biomass in Utah Lake. As of September 2009, an extensive carp removal program was instituted by the Department of Natural Resources and began the removal of 75% of the carp population. The purpose of this study is to assess the impact of carp removal on PCB levels in five sport fish species consumed by Utah citizens. The fish being analyzed are the Common Carp (Cyprinus carpio), Channel Catfish (Ictalurus punctatus), Black Bullhead (Ameiurus melas), Walleye (Sander vitreus), and White Bass (Morone chrysops). One-hundred twenty (120) fish were collected from Utah Lake and subcategorized by their gender, tissue type (fillet and offal), weight, and size: small (under 33 cm), medium (33 cm - 43 cm), and large (greater than 43 cm). This was done in order to determine the variation of contaminant levels in each subcategory. PCB analysis was performed by Utility Testing Laboratory in Salt Lake City, Utah. Results show there has been a significant increase in PCB levels in all fish species in comparison with the state reports (2008). All fish species have exceeded the EPA cancer screening level, except for the fillet tissue of the White Bass species. In Common Carp fillet, and offal decreased concentrations of 11.80% and 23.72%, respectively. In Channel catfish: the PCB levels in the fillet increase by 87.93%, however, the offal levels decrease by 5.16%. In Black Bullhead catfish: both fillet and offal increase by large amounts (5464.37% and 1047.46%, respectively). Elevated levels that surpass the EPA cancer screening level have been found in all fish, except for the fillet tissue of the White Bass species. These results indicate that fish investigated in this study may not be safe for human consumption.

In clinical studies, topiramate (TPM) was shown to cause a dose-dependent increase in the clearance of ethinyl estradiol. We hypothesized that this interaction results from induction of hepatic cytochrome P450 (CYP) 3A4 by TPM. Accordingly, we investigated whether TPM induces CYP3A4 in primary human hepatocytes and activates the human pregnane X receptor (hPXR), a nuclear receptor that serves as a regulator of CYP3A4 transcription. Human hepatocytes were treated for 72 h with TPM (10, 25, 50, 100, 250, and 500 microM) and known inducers, phenobarbital (PB; 2 mM), and rifampicin (10 microM). The rate of testosterone 6beta-hydroxylation by hepatocytes served as a marker for CYP3A4 activity. The CYP3A4-specific protein and mRNA levels were determined by using Western and Northern blot analyses, respectively. The hPXR activation was assessed with cell-based reporter gene assay. Compared with controls, TPM (50-500 microM)-treated hepatocytes exhibited a considerable increase in the CYP3A4 activity (1. 6- to 8.2-fold), protein levels (4.6- to 17.3-fold), and mRNA levels (1.9- to 13.3-fold). Comparatively, rifampicin (10 microM) effected 14.5-, 25.3-, and a 20.3-fold increase in CYP3A4 activity, immunoreactive protein levels, and mRNA levels, respectively. TPM (50-500 microM) caused 1.3- to 3-fold activation of the hPXR, whereas rifampicin (10 microM) caused a 6-fold activation. The observed induction of CYP3A4 by TPM, especially at the higher concentrations, provides a potential mechanistic explanation of the reported increase in the ethinyl estradiol clearance by TPM. It also is suggestive of other potential interactions when high-dose TPM therapy is used.

Secondary prevention guidelines after myocardial infarction (MI) are gender neutral, but underutilisation of treatment in women has been reported. We investigated the change in total and low-density lipoprotein (LDL) cholesterol levels and lipid-lowering drug (LLD) use after first-ever MI in a population-based study. We followed 10,005 participants (54% women) attending the Tromsø Study 1994-1995 and 8483 participants (55% women) attending the Tromsø Study 2007-2008 for first-ever MI up to their participation in 2007-2008 and 2015-2016, respectively. We used linear and logistic regression models to investigate sex differences in change in lipid levels. A total of 395 (MI cohort I) and 132 participants (MI cohort II) had a first-ever MI during 1994-2008 and 2007-2013, respectively. Mean change in total cholesterol was -2.34 mmol/L (SD 1.15) in MI cohort I, and in LDL cholesterol was -1.63 mmol/L (SD 1.12) in MI cohort II. Men had a larger decrease in lipid levels compared to women: the linear regression coefficient for change was -0.33 (95% confidence interval [CI] -0.51 to -0.14) for total cholesterol and -0.21 (95% CI -0.37 to -0.04) for LDL cholesterol, adjusted for baseline lipid value, age and cohort. Men had 73% higher odds (95% CI 1.15-2.61) of treatment target achievement compared to women, adjusted for baseline lipid value, age and cohort. LLD use was reported in 85% of women and 92% of men in MI cohort I, and 80% in women and 89% in men in MI cohort II. Compared to men, women had significantly less decrease in lipid levels after MI, and a smaller proportion of women achieved the treatment target.

Palatable food is a strong activator of the reward circuitry and may cause addictive behavior leading to eating disorders. How early life events and sex interact in shaping hedonic sensitivity to palatable food is largely unknown. We used prenatally restraint stressed (PRS) rats, which show abnormalities in the reward system and anxious/depressive-like behavior. Some of the hallmarks of PRS rats are known to be sex-dependent. We report that PRS enhanced and reduced milk chocolate-induced conditioned place preference in males and females, respectively. Male PRS rats also show increases in plasma dihydrotestosterone (DHT) levels and dopamine (DA) levels in the nucleus accumbens (NAc), and reductions in 5-hydroxytryptamine (5-HT) levels in the NAc and prefrontal cortex (PFC). In male rats, systemic treatment with the DHT-lowering drug finasteride reduced both milk chocolate preference and NAc DA levels. Female PRS rats showed lower plasma estradiol (E 2 ) levels and lower DA levels in the NAc, and 5-HT levels in the NAc and PFC. E 2 supplementation reversed the reduction in milk chocolate preference and PFC 5-HT levels. In the hypothalamus, PRS increased ERα and ERβ estrogen receptor and CARTP (cocaine-and-amphetamine receptor transcript peptide) mRNA levels in males, and 5-HT 2 C receptor mRNA levels in females. Changes were corrected by treatments with finasteride and E 2 , respectively. These new findings show that early life stress has a profound impact on hedonic sensitivity to high-palatable food via long-lasting changes in gonadal hormones. This paves the way to the development of hormonal strategies aimed at correcting abnormalities in the response to natural rewards. © 2015 Society for the Study of Addiction.

This project measured 2-hour integrated concentrations of PM10, PM2.5, metals and a number of organic chemicals including benzene and MTBE inside vehicles on California roadways. Using continuous samplers, particle counts, black carbon, and CO were also measured. In addition to measuring in-vehicle levels, the investigators measured pollutant levels just outside the vehicle, at roadside stations, and ambient air monitoring stations. Different driving scenarios were designed to assess the effects of a number of factors on in-vehicle pollutant levels. These factors included roadway type, carpool lanes, traffic conditions, geographical locations, vehicle type, and vehicle ventilation conditions. The statewide average in-vehicle concentrationsmore » of benzene, MTBE, and formaldehyde ranged from 3--22 {micro}g/m{sup 3}, 3--90 {micro}g/m{sup 3}, and 0---22 {micro}g/m{sup 3}, respectively. The ranges of mean PM10 and PM2.5 in-vehicle levels in Sacramento were 20--40 {micro}g/m{sup 3} and 6--22 {micro}g/m{sup 3}, respectively. In general, pollutant levels inside or just outside the vehicles were higher than those measured at the roadside stations or the ambient air stations. In-vehicle pollutant levels were consistently higher in Los Angeles than Sacramento. Pollutant levels measured inside vehicles traveling in a carpool lane were much lower than those in the right-hand, slower lanes. Under the study conditions, factors such as vehicle type and ventilation and little effect on in-vehicle pollutant levels. Other factors, such as roadway type, freeway congestion level, and time-of-day had some influence on in-vehicle pollution levels.« less

Background Coffee may have hepatoprotective effects and higher coffee consumption has been associated inversely with levels of liver enzymatic markers. However, it is unclear whether decaffeinated coffee is also associated with liver enzymes. Methods The study population included 27,793 participants, age 20 or older, in the US National Health and Nutrition Examination Survey (1999–2010). Coffee intake was evaluated by 24-hour dietary recall. Serum levels of aminotransferase (ALT), aminotransferase (AST), alkaline phosphatase (ALP) and gamma glutamyl transaminase (GGT) were measured. We examined the relationship between coffee intake and enzymatic levels using weighted multiple variable logistic (abnormally elevated levels of enzymes) and linear regression (continuous enzymatic levels). Results Total coffee consumption was inversely associated with abnormal levels of all four liver enzymes and continuous levels of AST, ALP and GGT. Compared to those reporting no coffee consumption, participants reporting ≥3 cups per day had an odds ratio (OR) (95% confidence interval (CI)) of 0.75 (0.63, 0.89)), 0.82 (0.68, 0.98), 0.73 (0.55, 0.95) and 0.69 (0.57, 0.83) for abnormal levels of ALT, AST, ALP and GGT, respectively. Similar inverse associations were found with decaffeinated coffee intake and abnormal levels of ALT (OR≥2 vs 0 cup/d: 0.62 (0.41, 0.94)), AST (0.74 (0.49, 1.11)), and GGT (0.70, 0.49–1.00). Conclusion Higher intakes of coffee, regardless of its caffeine content, were associated with lower levels of liver enzymes. PMID:25124935

Poor adherence to a low-sodium diet (LSD) and prescribed medications increases rehospitalization risk in patients with heart failure (HF). Clinicians have difficulty assessing adherence objectively, so they depend on patients' self-report. The degree to which self-reported adherence reflects actual adherence is unclear. We examined patients' ability to self-monitor adherence to an LSD and medications by comparing self-reported adherence with objective evidence of adherence. A total of 133 patients with HF (male 71%; ejection fraction 35% +/- 14%) completed the Medical Outcomes Study Specific Adherence Scale. Adherence to the LSD and medication were assessed objectively using 24-hour urinary sodium excretion and dose counting with an electronic monitoring device, respectively. On the basis of self-report, patients were divided into adherent and non-adherent groups and evaluated for differences according to objective adherence. There were no differences in urinary sodium levels between the self-reported LSD adherent and non-adherent groups (4560 mg vs. 4333 mg; P = .59). Self-reported adherent and non-adherent medication groups took 92.4% and 80.4% of prescribed doses, respectively (P < .001). Patients were able to accurately estimate adherence to medication, but they failed to estimate LSD adherence. This finding suggests that we need to improve our means of evaluating adherence to the LSD and of educating patients more thoroughly about following the LSD. We speculated that the inability to estimate LSD adherence may be the result of gaps in patients' knowledge that preclude accurate self-assessment.

Sitting behaviours have increased markedly during the last two decades in Chile. However, their associations with health outcomes such as diabetes have not been reported. Therefore, the aim of this study was to investigate the independent association of self-reported sitting time with diabetes-related markers and diabetes prevalence in Chile. This cross-sectional study included participants (aged ≥18 years) from the Chilean National Health Survey 2009-10 (n = 4457). Fasting glucose and haemoglobin A1c (HbA1c) were measured by standardized protocols. The prevalence of type 2 diabetes (T2D) was determined using WHO criteria. Physical activity (PA) and time spent sitting were determined using the Global Physical Activity Questionnaire (GPAQ). The odds ratio for T2D was 1.10 [95% CI: 1.04-1.16, P = 0.002] and 1.08 [1.02-1.14, P = 0.002] per 1 h increase in sitting time in men and women, respectively, independent of age, education, smoking, BMI and total PA. Overall, prevalence of T2D was 10.2 and 17.2% in individuals classified in the lowest and highest categories of sitting time, respectively. No significant associations were found between sitting time and glucose or HbA1c. Sitting time is positively associated with diabetes risk, independent of socio-demographic, obesity and PA levels, in the Chilean population. © The Author 2017.

There is a lack of scientific literature regarding the bioaccumulation, dietary and toxicity exposure of PCN via food crops. The current study presents the information of dietary intake, distribution pattern and screening level risk assessment of PCN in wheat, rice, soil and air along upstream feeding tributaries of the River Chenab, Punjab Province, Pakistan. A total six air and twenty eight of soil, wheat and rice samples were collected during Jan, 2013 to June, 2013 to analyze the thirty nine PCN congeners. ∑39PCN concentrations were ranged between 0.02 and 0.21 ng g(-1) dw, 0.02-1.21 ng g(-1) dw, 24.6-233 ng g(-1) dw and 1,222-5,052 pg m(-3) in wheat, rice, soil and air samples, respectively. In this study soil exhibited higher TEQ values while in case of air, wheat and rice TEQ concentrations were in accordance with the previously reported pattern from other parts of the world. Estimated daily intake (EDI) of ∑39PCN through consumption of wheat and rice was estimated as 0.21 ng kg(-1) (body weight)day(-1) and 0.03 ng kg(-1) (body weight)day(-1), respectively. This is the first report of PCN dietary intake and screening-level risk assessment by consumption of cereal crops from Pakistan. The results of dietary and toxicity exposure of PCN warrant auxiliary devotion in future, to this group of contaminant. Copyright © 2014 Elsevier B.V. All rights reserved.

Musculoskeletal Dysfunctions in Patients With Chronic Pelvic Pain: A Preliminary Descriptive Survey.

The purpose of this study was to determine the prevalence of musculoskeletal dysfunctions based on a standardized clinical examination of patients with chronic pelvic pain (CPP) who were referred to a specialized tertiary care center for laparoscopic examination. In addition, we stratified levels of self-reported pelvic pain, self-rated health, education, and work status based on musculoskeletal dysfunction status. This study used a cross-sectional design to determine the prevalence of musculoskeletal dysfunctions in women with CPP who were referred to a tertiary care center specializing in care of women with CPP. The women completed a questionnaire and underwent a blinded systematic objective clinical examination of the musculoskeletal system by a doctor of chiropractic who then categorized the patients as having or not having musculoskeletal dysfunction. Ninety-four patients returned the questionnaire, completed the clinical examination, and fulfilled the inclusion criteria. More than half of the referred patients with CPP (48 out of 94) had musculoskeletal dysfunctions in the lumbar/pelvic region. No statistically significant differences were found between the groups with respect to self-rated health, education, work status, and pain level. Pain location was significantly different after Bonferroni correction in 1 out of the 36 aspects. In this sample of CPP patients, 51% were categorized as having a musculoskeletal dysfunction. Overall, CPP patients were similar with respect to certain characteristics, such as age, body mass index, and pain level, regardless of their classification; however, patients with musculoskeletal dysfunction tended to report more pain in the front and back of the lower limbs.

Release of NLCD 2006 provides the first wall-to-wall land-cover change database for the conterminous United States from Landsat Thematic Mapper (TM) data. Accuracy assessment of NLCD 2006 focused on four primary products: 2001 land cover, 2006 land cover, land-cover change between 2001 and 2006, and impervious surface change between 2001 and 2006. The accuracy assessment was conducted by selecting a stratified random sample of pixels with the reference classification interpreted from multi-temporal high resolution digital imagery. The NLCD Level II (16 classes) overall accuracies for the 2001 and 2006 land cover were 79% and 78%, respectively, with Level II user's accuracies exceeding 80% for water, high density urban, all upland forest classes, shrubland, and cropland for both dates. Level I (8 classes) accuracies were 85% for NLCD 2001 and 84% for NLCD 2006. The high overall and user's accuracies for the individual dates translated into high user's accuracies for the 2001–2006 change reporting themes water gain and loss, forest loss, urban gain, and the no-change reporting themes for water, urban, forest, and agriculture. The main factor limiting higher accuracies for the change reporting themes appeared to be difficulty in distinguishing the context of grass. We discuss the need for more research on land-cover change accuracy assessment.

To develop a MS-based selected reaction monitoring (SRM) assay for quantitation of myeloid-derived growth factor (MYDGF) formerly chromosome 19 open reading frame (C19orf10). Candidate reporter peptides were identified in digests of recombinant MYDGF. Isotopically labeled forms of these reporter peptides were employed as internal standards for assay development. Two reference peptides were selected SYLYFQTFFK and GAEIEYAMAYSK with respective LOQ of 42 and 380 attomole per injection. Application of the assay to human serum and synovial fluid determined that the assay sensitivity was reduced and quantitation was not achievable. However, the partial depletion of albumin and immunoglobulin from synovial fluids provided estimates of 300-650 femtomoles per injection (0.7-1.6 nanomolar (nM) fluid concentrations) in three of the six samples analyzed. A validated sensitive assay for the quantitation of MYDGF in biological fluids was developed. However, the endogenous levels of MYDGF in such fluids are at or below the current levels of quantitation. The levels of MYDGF are lower than those previously reported using an ELISA. The current results suggest that additional steps may be required to remove high abundance proteins or to enrich MYDGF for SRM-based quantitation. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

We report the hyperfine Structure (hfs) splitting observations of neutral iodine atom (II) in the 6000 - 10,000 cm-1 near infrared spectral region. The measurements were carried out using a high-resolution Fourier Transform Spectrometer (FTS), where an electrodeless discharge lamp (EDL), excited using microwaves, was employed as the light source and InGaAs as the light detector. A specially designed setup was used to lower the plasma temperature of the medium so as to reduce the Doppler width and consequently to increase the spectral resolution of hfs components. A total of 183 lines with hfs splitting have been observed, out of which hfs in 53 spectral lines are reported for the first time. On the basis of hfs analysis, we derived the magnetic dipole and electric quadrupole coupling constants, A and B respectively for 30 even and 30 odd energy levels and are compared with the values available in the literature. New hfs values for 5 even and 4 odd levels are also reported here for the first time.

Introduction Since adoption of the measles case-based surveillance system in Zimbabwe in 1998, data has been routinely collected at all levels of the health delivery system and sent to national level with little or no documented evidence of use to identify risky populations, monitor impact of interventions and measure progress towards achieving measles elimination. We analysed this data to determine trends in the national measles case-based surveillance system (NMCBSS). Methods A retrospective record review of the NMCBSS dataset for period 1999 –2008 was conducted, assessing trends in proportions of investigated cases; timeliness and nature of specimens received at laboratory; timeliness of feedback of serology results, proportion of cases confirmed as measles and national annualized rates of investigation. Comparisons with WHO performance indicators were done. The secondary data analysis was done in Excel and Epi-Info statistical software. Results Cumulatively 4994 suspected cases were reported and investigated between 1999 and 2008. Reported suspected and confirmed measles cases declined from 24, 5% and 5.9% respectively in 2000 to 3.9% and 1.0% respectively in 2008. Proportion of cases with blood specimens collected and proportion reaching laboratory timely increased from 83% and 65% respectively in 1999, to 100% and 82% respectively in 2008. Proportion of specimens arriving at laboratory in good condition improved from 65% in 2004 to 94% in 2008 while timeliness of feedback of serology results improved from 4% in 2004 to 65% in 2008. Sensitivity of the NMCBSS however has been weakening, declining from 9.04 cases investigated per 100 000 population per year in 2000 to 1.58 cases/100 000/year in 2008. Conclusion The NMCBSS improved in quality, timeliness and feedback of laboratory results of specimens sent for investigation, but its sensitivity declined mainly due to reduced capacity to detect and confirm measles cases. We recommend training staff on active surveillance of cases and more support and supervisory visits to strengthen EPI surveillance. PMID:22368745

Correlation consistent basis sets for lanthanides: The atoms La–Lu

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lu, Qing; Peterson, Kirk A., E-mail: kipeters@wsu.edu

Using the 3rd-order Douglas-Kroll-Hess (DKH3) Hamiltonian, all-electron correlation consistent basis sets of double-, triple-, and quadruple-zeta quality have been developed for the lanthanide elements La through Lu. Basis sets designed for the recovery of valence correlation (defined here as 4f5s5p5d6s), cc-pVnZ-DK3, and outer-core correlation (valence + 4s4p4d), cc-pwCVnZ-DK3, are reported (n = D, T, and Q). Systematic convergence of both Hartree-Fock and correlation energies towards their respective complete basis set (CBS) limits are observed. Benchmark calculations of the first three ionization potentials (IPs) of La through Lu are reported at the DKH3 coupled cluster singles and doubles with perturbative triples,more » CCSD(T), level of theory, including effects of correlation down through the 4s electrons. Spin-orbit coupling is treated at the 2-component HF level. After extrapolation to the CBS limit, the average errors with respect to experiment were just 0.52, 1.14, and 4.24 kcal/mol for the 1st, 2nd, and 3rd IPs, respectively, compared to the average experimental uncertainties of 0.03, 1.78, and 2.65 kcal/mol, respectively. The new basis sets are also used in CCSD(T) benchmark calculations of the equilibrium geometries, atomization energies, and heats of formation for Gd{sub 2}, GdF, and GdF{sub 3}. Except for the equilibrium geometry and harmonic frequency of GdF, which are accurately known from experiment, all other calculated quantities represent significant improvements compared to the existing experimental quantities. With estimated uncertainties of about ±3 kcal/mol, the 0 K atomization energies (298 K heats of formation) are calculated to be (all in kcal/mol): 33.2 (160.1) for Gd{sub 2}, 151.7 (−36.6) for GdF, and 447.1 (−295.2) for GdF{sub 3}.« less

Previous studies have reported that salivary concentrations of certain hormones correlate with their respective serum levels. However, most of these studies did not control for potential blood contamination in saliva. In the present study we developed a statistical method to test the amount of blood contamination that needs to be avoided in saliva samples for the following hormones: cortisol, estradiol, progesterone, testosterone and oxytocin. Saliva and serum samples were collected from 38 healthy, medication-free women (mean age=33.8±7.3yr.; range=19-45). Serum and salivary hormonal levels and the amount of transferrin in saliva samples were determined using enzyme immunoassays. Salivary transferrin levels did not correlate with salivary cortisol or estradiol (up to 3mg/dl), but they were positively correlated with salivary testosterone, progesterone and oxytocin (p<0.05). After controlling for blood contamination, only cortisol (r=0.65, P<0.001) and progesterone levels (r=0.57, P=0.002) displayed a positive correlation between saliva and serum. Our analyses suggest that transferrin levels higher than 0.80, 0.92 and 0.64mg/dl should be avoided for testosterone, progesterone and oxytocin salivary analyses, respectively. We recommend that salivary transferrin is measured in research involving salivary hormones in order to determine the level of blood contamination that might affect specific hormonal salivary concentrations.

Oxidative stress has been reported to elevate ceramide level during cell death. The purpose of the present study was to modulate cell death in relation to cellular glutathione (GSH) level and GST (glutathione S-transferase) expression by regulating the sphingolipid metabolism. LLC-PK1 cells were treated with H2O2 in the absence of serum to induce cell death. Subsequent to exposure to H2O2, LLC-PK1 cells were treated with desipramine, sphingomyelinase inhibitor, and N-acetylcysteine (NAC), GSH substrate. Based on comparative visual observation with H2O2-treated control cells, it was observed that 0.5 microM of desipramine and 25 mM of NAC exhibited about 90 and 95% of cytoprotection, respectively, against H2O2-induced cell death. Desipramine and NAC lowered the release of LDH activity by 36 and 3%, respectively, when compared to 71% in H2O2-exposed cells. Cellular glutathione level in 500 microM H2O2-treated cells was reduced to 890 pmol as compared to control level of 1198 pmol per mg protein. GST P1-1 expression was decreased in H2O2-treated cells compared to healthy normal cells. In conclusion, it has been inferred that H2O2-induced cell death is closely related to cellular GSH level and GST P1-1 expression in LLC-PK1 cells and occurs via ceramide elevation by sphingomyelinase activation.

Objectives Our aim was to report the first known incidence of U.S. butter contamination with extremely high levels of polybrominated diphenyl ethers (PBDEs). Methods Ten butter samples were individually analyzed for PBDEs. One of the samples and its paper wrapper contained very high levels of higher-brominated PBDEs. Dietary estimates were calculated using the 2007 U.S. Department of Agriculture Loss-Adjusted Food Availability data, excluding the elevated sample. Results The highly contaminated butter sample had a total upper bound PBDE level of 42,252 pg/g wet weight (ww). Levels of brominated diphenyl ether (BDE)-206, -207, and -209 were 2,000, 2,290, and 37,600 pg/g ww, respectively. Its wrapping paper contained a total upper-bound PBDE concentration of 804,751 pg/g ww, with levels of BDE-206, -207, and -209 of 51,000, 11,700, and 614,000 pg/g, respectively. Total PBDE levels in the remaining nine butter samples ranged from 180 to 1,212 pg/g, with geometric mean of 483 and median of 284 pg/g. Excluding the outlier, total PBDE daily intake from all food was 22,764 pg/day, lower than some previous U.S. dietary intake estimates. Conclusion Higher-brominated PBDE congeners were likely transferred from contaminated wrapping paper to butter. A larger representative survey may help determine how frequently PBDE contamination occurs. Sampling at various stages in food production may identify contamination sources and reduce risk.

An inconsistent relationship between physical activity and neck/shoulder pain (NSP) in adolescents has been reported in the literature. Earlier studies may be limited by not assessing physical activity in sufficient detail. The aim of this study was to comprehensively examine the association between NSP and the level and nature of physical activity, and type of sedentary activity in adolescents. A cross-sectional analysis using data from 924 adolescents in the Western Australian Pregnancy Cohort (RAINE) study was performed. Complete data were available for 643 adolescents (54.6% female) at the 14-year follow-up. Physical activity was measured using a detailed self-report electronic activity diary requiring participants to input details of all physical activities over the day in segments of 5 minutes for a one-week period. Physical activity levels were categorised as: sedentary, light, moderate, or vigorous based on metabolic energy equivalents. Nature of activity was determined by assigning each activity to categories based on the amount of movement (static/dynamic) and the main posture assumed for the activity (standing/sitting/lying). Type of sedentary activity was characterised by exposure time to watching TV, using a computer, and reading. Logistic regression was used to explore the association between NSP and activity. Females reported a higher prevalence of lifetime, 1-month and chronic NSP than males (50.9 vs 41.7%, 34.1 vs 23.5%, and 9.2 vs 6.2% respectively). No consistent, dose-response relationship was found between NSP and the level, nature, and type of physical activity. Self-reported one month and lifetime NSP prevalence in adolescents is not related to the level or intensity of physical activity or the type of sedentary activity over a one week period.

Financial concerns are often cited by physicians as a barrier to administering routinely recommended vaccines to adults. The purpose of this study was to assess perceived payments and profit from administering recommended adult vaccines and vaccine purchasing practices among general internal medicine (GIM) and family medicine (FM) practices in the United States. We conducted an interviewer-administered survey from January-June 2014 of practices stratified by specialty (FM or GIM), affiliation (standalone or ≥ 2 practice sites), and level of financial decision-making (independent or larger system level) in FM and GIM practices that responded to a previous survey on adult vaccine financing and provided contact information for follow-up. Practice personnel identified as knowledgeable about vaccine financing and billing responded to questions about payments relative to vaccine purchase price and payment for vaccine administration, perceived profit on vaccination, claim denial, and utilization of various purchasing strategies for private vaccine stocks. Survey items on payment and perceived profit were assessed for various public and private payer types. Descriptive statistics were calculated and responses compared by physician specialty, practice affiliation, and level of financial decision-making. Of 242 practices approached, 43% (n = 104) completed the survey. Reported payment levels and perceived profit varied by payer type. Only for preferred provider organizations did a plurality of respondents report profiting on adult vaccination services. Over half of respondents reported losing money vaccinating adult Medicaid beneficiaries. One-quarter to one-third of respondents reported not knowing about Medicare Part D payment levels for vaccine purchase and vaccine administration, respectively. Few respondents reported negotiating with manufacturers or insurance plans on vaccine purchase prices or payments for vaccination. Practices vaccinating adults may benefit from education and technical assistance related to vaccine financing and billing and greater use of purchasing strategies to decrease upfront vaccine cost.

The development of Electronic Health Records (EHRs) forms an integral part of the information strategy for the National Health Service (NHS) in the UK, with the aim of facilitating health information exchange for patient care and secondary use, including research and healthcare planning. Implementing EHR systems requires an understanding of patient expectations for consent mechanisms and consideration of public awareness towards information sharing as might be made possible through integrated EHRs across primary and secondary health providers. To explore levels of public awareness about EHRs and to examine attitudes towards different consent models with respect to sharing identifiable and de-identified records for healthcare provision, research and planning. A cross-sectional questionnaire survey was administered to adult patients and members of the public in primary and secondary care clinics in West London, UK in 2011. In total, 5331 individuals participated in the survey, and 3157 were included in the final analysis. The majority (91%) of respondents expected to be explicitly asked for consent for their identifiable records to be accessed for health provision, research or planning. Half the respondents (49%) did not expect to be asked for consent before their de-identified records were accessed. Compared with White British respondents, those from all other ethnic groups were more likely to anticipate their permission would be obtained before their de-identified records were used. Of the study population, 59% reported already being aware of EHRs before the survey. Older respondents and individuals with complex patterns of interaction with healthcare services were more likely to report prior awareness of EHRs. Individuals self-identifying as belonging to ethnic groups other than White British, and those with lower educational qualifications were less likely to report being aware of EHRs than White British respondents and respondents with degree-level education, respectively. Those who reported being aware of EHRs were less likely to say they expected explicit consent to be sought before use of their de-identified record. A large number of patients remain unaware of EHRs, while preference for implicit consent is stronger among those who report previous awareness. Differences in awareness levels and consent expectations between groups with different socio-demographic characteristics suggest that public education and information campaigns should target specific groups to increase public awareness and ensure meaningful informed consent mechanisms.

Experimental Energy Levels and Partition Function of the 12C2 Molecule

NASA Astrophysics Data System (ADS)

Furtenbacher, Tibor; Szabó, István; Császár, Attila G.; Bernath, Peter F.; Yurchenko, Sergei N.; Tennyson, Jonathan

2016-06-01

The carbon dimer, the 12C2 molecule, is ubiquitous in astronomical environments. Experimental-quality rovibronic energy levels are reported for 12C2, based on rovibronic transitions measured for and among its singlet, triplet, and quintet electronic states, reported in 42 publications. The determination utilizes the Measured Active Rotational-Vibrational Energy Levels (MARVEL) technique. The 23,343 transitions measured experimentally and validated within this study determine 5699 rovibronic energy levels, 1325, 4309, and 65 levels for the singlet, triplet, and quintet states investigated, respectively. The MARVEL analysis provides rovibronic energies for six singlet, six triplet, and two quintet electronic states. For example, the lowest measurable energy level of the {{a}}{}3{{{\\Pi }}}{{u}} state, corresponding to the J = 2 total angular momentum quantum number and the F 1 spin-multiplet component, is 603.817(5) cm-1. This well-determined energy difference should facilitate observations of singlet-triplet intercombination lines, which are thought to occur in the interstellar medium and comets. The large number of highly accurate and clearly labeled transitions that can be derived by combining MARVEL energy levels with computed temperature-dependent intensities should help a number of astrophysical observations as well as corresponding laboratory measurements. The experimental rovibronic energy levels, augmented, where needed, with ab initio variational ones based on empirically adjusted and spin-orbit coupled potential energy curves obtained using the Duo code, are used to obtain a highly accurate partition function, and related thermodynamic data, for 12C2 up to 4000 K.

Circadian rhythm of blood and urinary copper has been studied in presumably healthy subjects of a particular ethnic group in India who are vegetarians. A definite 24-hr variation has been observed for both blood and urinary copper. The peak for blood copper was 1500 hr and the lowest value was 0600 hr, with values of 0.185 mg/100 ml and 0.160 mg/100 ml respectively. The urinary peak and trough occurred at 0600 and 0300 hr, respectively. Remarkably higher 24-hr copper excretion values were noted (64.49 ..mu..g/day) with a range of 15-100 ..mu..g/day. The blood level of copper (0.134 mg/100 ml) remainedmore » within the range reported. One subject out of 25 deviated from the group with respect to circadian phasing and amplitude to urinary copper excretion. 20 references.« less

Here we present the first report of a carbon-γ-Fe₂O₃ nanoparticle composite of mesoporous carbon, bearing COOH- and phenolic OH- functional groups on its surface, a remarkable and magnetically separable adsorbent, for the radioactive material emitted by the Fukushima Daiichi nuclear power plant accident. Contaminated water and soil at a level of 1,739 Bq kg(-1) ((134)Cs and (137)Cs at 509 Bq kg(-1) and 1,230 Bq kg(-1), respectively) and 114,000 Bq kg(-1) ((134)Cs and (137)Cs at 38,700 Bq kg(-1) and 75,300 Bq kg(-1), respectively) were decontaminated by 99% and 90% respectively with just one treatment carried out in Nihonmatsu city in Fukushima. Since this material is remarkably high performance, magnetically separable, and a readily applicable technology, it would reduce the environmental impact of the Fukushima accident if it were used.

The prevalence of metabolic syndrome is consistently increasing among Korean adults and is reported to be particularly high among older adults in Korea. This paper reports the prevalence of metabolic syndrome and identifies the association between metabolic syndrome and physical activity in Korean older adults. Subjects of this study were 3653 older adults who participated in the fourth Korean National Health and Nutrition Examination Survey during the years 2007-2009. The prevalence of metabolic syndrome in the study population was 46.84%. The prevalences of abdominal obesity, elevated fasting glucose, elevated triglycerides, reduced high-density lipoprotein cholesterol, and elevated blood pressure were 39.51, 45.53, 39.55, 48.24, and 69.14%, respectively, in the study population. Compared to subjects who reported low levels of physical activity, the odds ratios of metabolic syndrome for those who were moderately active and highly active were 0.93 and 0.63, respectively. Nurses should develop metabolic syndrome management programs that are tailored to the needs of the targeted group and that include individually adapted physical activity programs to promote health. © 2013 Wiley Publishing Asia Pty Ltd.

The trace element contents of five varieties of instant coffee powder available in the Indian market have been analysed. Ca, Cr, Fe, K, Mg, Mn, Ni, Sr, Zn and Pb, Cd, Cu have been determined using atomic absorption spectrophotometry and differential pulse anodic stripping voltammetry, respectively. The metal levels in the coffee powders observed in this study are comparable with those reported for green coffe beans (Arabica and Robusta variety) reported worldwide with the exception of Sr and Zn, which were on the lower side of the reported values. Concentrations of these metals have been converted into intake figures based on coffee consumption. The daily intakes of the above metals through ingestion of coffee are 1.4 mg, 1.58 microg, 124 microg, 41.5 mg, 4.9 mg, 17.9 microg, 2.9 microg, 3.8 microg, 12.5 microg, 0.2 microg, 0.03 microg and 15.5 microg, respectively. The values, which were compared with the total dietary, intake of metals through ingestion by the Mumbai population, indicate that the contribution from coffee is less than or around 1% for most of the elements except for Cr and Ni which are around 3%.

The purpose of this study is to investigate associations between physical activity (PA), depression, and anxiety among adolescents in Ireland. Adolescents (N = 481; 281 male, 200 female) aged 15.1 ± 1.7y self-reported PA level, depression, and anxiety. Approximately 21% of adolescents were high trait anxious, and ∼37% reported scores indicating probable depression. Anxiety and depressive symptoms were higher for low PA (60 min/d, 0-2 d/wk) compared to moderate (60 min/d, 3-4 d/wk) and high (60 min/d, 5-7 d/wk) PA. After adjustment for relevant covariates, reduced odds of depression were 30% and 56% for moderate and high PA, respectively; reduced odds of high trait anxiety were 46% and 47% for moderate and high PA, respectively. These findings support the need for adolescents to engage in moderate PA, with potential for increased benefits with increased PA. To conclude, moderate and high PA are inversely associated with anxiety and depressive symptoms, and risk of depression and high trait anxiety in adolescents.

Sulfur compounds, such as sulfite (SO(2)), hydrogen sulfide (H(2)S), and glutathione (GSH), play different roles in beer flavor stability. SO(2) and GSH have antiaging effects which are helpful to improve the flavor stability of beer, whereas H(2)S is undesirable to beer flavor because of its unpleasant aroma. Here, we report the development of Saccharomyces cerevisiae which produces higher levels of SO(2) and GSH but lower level of H(2)S to improve beer flavor stability by nongenetic engineering approaches. After two rounds of UV mutagenesis coupled with specific plate screening methods, one promising mutant named MV16 was obtained. Compared with the original strain, the SO(2) and GSH production of MV16 in fermenting liquor increased by 31% and 30.2%, respectively, while H(2)S content decreased by 74.9%, and the DPPH radical clearance and the resistance staling value of beer fermented by MV16 increased by 24.6% and 33.0%, respectively. The antioxidizability of the mutant was improved significantly. The strategy adopted in our study could be used to obtain S. cerevisiae of improved antiaging properties, and the mutant would be safe for public use.

The study evaluated 1-piece implants in daily clinical situations. One-piece implants restoring both single teeth and partially edentulous sites were included. A single-stage procedure was used with immediate provisionalization within 24 hours after surgery. The definitive prosthesis was delivered within 6 months of implant insertion. One hundred fifteen implants have been placed in 84 patients at 4 centers. Two implants failed resulting in a cumulative survival rate of 98.3%. Normal periimplant mucosa and no visible plaque were observed in most of the implants. The soft tissue papilla scores improved considerably over time P < 0.001. Patient assessment improved significantly from implant insertion to the 3-year visit, P < 0.001. The mean bone level at implant insertion, 6-month, and 1-, 2-, and 3-year visits was 0.42, -0.58, -0.69, -0.80, and -0.66 mm, respectively. The mean change in bone level from implant insertion to 6 months and 1, 2, and 3 years was reported as -1.02, -1.12, -1.26, and -1.07 mm, respectively. The results indicate that this implant has the ability to preserve both hard and soft tissues' architecture.

An experimental study of growth and phase change of polar stratospheric cloud particles

This report describes the progress made on understanding phase changes related to solutions which may comprise Polar Stratospheric Clouds. In particular, it is concerned with techniques for investigating specific classes of metastability and phase change which may be important not only in Polar Stratospheric Clouds but in all atmospheric aerosols in general. While the lower level atmospheric aerosol consists of mixtures of (NH4)(SO4)2, NH4HSO4, NaCl among others, there is evidence that aerosol at PSC levels is composed of acid aerosol, either injected from volcanic events (such as Pinatubo) or having diffused upward from the lower atmosphere. In particular, sulfuric acid and nitric acid are known to occur at PSC levels, and are suspected of catalyzing ozone destruction reactions by adsorption on surfaces of crystallized particles. The present study has centered on two approaches: (1) the extent of supercooling (with respect to ice) and supersaturation (with respect to hydrate) and the nature of crystal growth in acid solutions of specific molality; and (2) the nature of growth from the vapor of HNO3 - H2O crystals both on a substrate and on a pre-existing aerosol.

Fibromyalgia (FM) is characterized by chronic, widespread pain, fatigue, and other symptoms; yet few studies have comprehensively assessed its humanistic burden. This observational study evaluates the impact of FM severity on patients' symptoms, health-related quality of life (HRQoL), and productivity in the United States. 203 FM subjects were recruited from 20 physician offices. Subjects completed a questionnaire including the EuroQol 5D (EQ-5D), Fibromyalgia Impact Questionnaire (FIQ), Multidimensional Assessment of Fatigue (MAF), Medical Outcomes Study Sleep Scale (MOS-SS), and Hospital Anxiety and Depression Scale (HADS) and questions about demographics, pain and other symptoms, HRQoL and productivity. FIQ total scores were used to define FM severity, with 0- < 39, 39- < 59, and 59-100, representing mild, moderate, and severe FM, respectively. Sites recorded subjects' clinical characteristics and FM treatment on case report forms using medical records. Summary statistics were calculated for continuous variables and frequency distributions for categorical variables. Differences across FM severity groups were evaluated using the Kruskal-Wallis or Chi-square tests. Statistical significance was evaluated at the 0.05 level. Mean (SD) age was 47.9 (10.9); 95% were female. Most (92%) were prescribed medication for FM; 24% and 66% reported moderate and severe FM, respectively. Mean (SD) scores were: 6.3 (2.1) for pain intensity; 0.35 (0.35) for EQ-5D; 30.7 (14.2) for MAF; 57.5 (18.4) for MOS-SS Sleep Problems Index; 10.2 (4.8) for HADS anxiety and 9.4 (4.4) for HADS depression. Subjects with worse FM severity reported significantly increased pain severity, HRQoL, fatigue, sleep disturbance, anxiety and depression (p < 0.001). Overall, 50% of subjects reported some disruption in their employment due to FM; this differed across severity levels (p < 0.001). Employed subjects missed a mean (SD) of 1.8 (3.9) workdays during the past 4 weeks; this also differed across severity levels (p = 0.03). FM imposes a substantial humanistic burden on patients in the United States, and leads to substantial productivity loss, despite treatment. This burden is higher among subjects with worse FM severity.

Adverse childhood experiences and psychosocial well-being of women who were in foster care as children.

Research has shown that many children in foster care later have psychosocial problems as adults; this is often attributed to cumulative adversities and a lack of supportive caregivers. The risk factors associated with foster care, such as maternal separation and multiple placements, often counteract many protective factors that can ameliorate the effects of childhood adversities. This study assessed the relationship between adverse childhood experiences (ACEs) and psychosocial well-being in women who were in foster care as children. A total of 101 women aged 18-71 years (mean, 36.83 [12.95] years) completed an anonymous online survey based on the 10-item ACE Questionnaire, the Sense of Coherence questionnaire, and the General Health Questionnaire. More than 56% of respondents were identified as experiencing current psychological distress. Sense of coherence scores (mean, 54.26 [15.35]) showed a significant inverse association with both General Health Questionnaire (mean, 14.83 [5.88]) and ACE (mean, 5.68 [2.90]) scores (r = -0.64 and -0.31, respectively) and 97% reported at least 1 ACE, 70% reported ≥ 5 and 33% reported ≥ 8. Linear regressions indicated that ACEs reported to occur before foster care were associated with lower levels of sense of coherence (8%) and higher levels of psychological distress (6%). Physical neglect and living in a dysfunctional household (parental loss, maternal abuse, or household member associated with substance abuse or prison) significantly decreased during foster care by 16 and 19 percentage points, respectively. Rates of emotional and physical abuse did not change. The number of ACEs was associated with the level of psychological distress. Our findings suggest that children entering the foster care system are already vulnerable and at risk of experiencing ACEs during foster care and psychological distress during adulthood. Measures implemented to protect children must not cause more harm than good. Social services that preserve and strengthen the family unit and reduce the number of ACEs both before and during foster care are recommended. Social workers and clinicians who are trained to address and manage the unique developmental needs of children in foster care may help reduce the effects of ACEs and optimize developmental health.

Young adult solid organ transplant recipients who transfer from pediatric to adult care experience poor outcomes related to decreased adherence to the medical regimen. Our pilot trial for young adults who had heart transplant (HT) who transfer to adult care tests an intervention focused on increasing HT knowledge, self-management and self-advocacy skills, and enhancing support, as compared to usual care. We report baseline findings between groups regarding (1) patient-level outcomes and (2) components of the intervention. From 3/14 to 9/16, 88 subjects enrolled and randomized to intervention (n = 43) or usual care (n = 45) at six pediatric HT centers. Patient self-report questionnaires and medical records data were collected at baseline, and 3 and 6 months after transfer. For this report, baseline findings (at enrollment and prior to transfer to adult care) were analyzed using Chi-square and t-tests. Level of significance was p < 0.05. Baseline demographics were similar in the intervention and usual care arms: age 21.3 ± 3.2 vs 21.5 ± 3.3 years and female 44% vs 49%, respectively. At baseline, there were no differences between intervention and usual care for use of tacrolimus (70 vs 62%); tacrolimus level (mean ± SD = 6.5 ± 2.3 ng/ml vs 5.6 ± 2.3 ng/ml); average of the within patient standard deviation of the baseline mean tacrolimus levels (1.6 vs 1.3); and adherence to the medical regimen [3.6 ± 0.4 vs 3.5 ± 0.5 (1 = hardly ever to 4 = all of the time)], respectively. At baseline, both groups had a modest amount of HT knowledge, were learning self-management and self-advocacy, and perceived they were adequately supported. Baseline findings indicate that transitioning HT recipients lack essential knowledge about HT and have incomplete self-management and self-advocacy skills.

to investigate the association between objective measures of physical activity levels, physical fitness and screen time in Colombia children and adolescents from Bogota, Colombia. a sample of 149 healthy Colombian youth, children and adolescents (9-17.9 years old) participated in the study. Physical activity level was assessed over 7 days using an accelerometer. Weight, height, waist circumference, hip waist, subscapular/ triceps skinfold thicknesses and self-reported screen time (television/internet and videogame-viewing time) were measured. Aerobic capacity, handgrip strength, standing broad jump, vertical jump, speed/agility and flexibility were used as indicators of physical fitness. in girls with a high level of physical activity had favorable aerobic capacity (r = 0.366) and inverse relationship with subscapular/triceps skinfold thicknesses (r = -0.257) and (r = -0,237) p < 0.05, respectively. In boys, vigorous physical activity were associated with higher values of flexibility (r = 0.277) and aerobic capacity (r = 0.347), p < 0.05. Finally, the participants who watched 2 h or less of television per day showed 1.81 times (95%CI 1.401 to 2.672) that met physical activity guidelines. the healthy Colombian youth who reported moderate to vigorous objective measures of physical activity levels, presented higher levels in physical fitness especially in aerobic capacity and flexibility and lower values in subscapular/triceps skinfold thicknesses.

This study provides information on the current status of contamination by polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) in the tissues of endangered White-backed Vulture Gyps bengalensis in India. Chemical analyses revealed detectable amounts of PAHs, PCBs, and OCPs. Concentration ranges of ∑PAHs, ∑PCBs, and ∑OCPs in tissues were 60–2037 ng/g, 30–5790 ng/g, and 3.2–5836 ng/g wet weight, respectively. 1,1-Dichloro-2,2-bis(p-chlorophenyl)ethylene (p,p′-DDE) concentrations ranged from below detectable level to 599 ng/g wet weight, representing more than 90% of the total dichlorodiphenyltrichloroethane (DDT). Among the various OCPs analyzed, p,p′-DDE was detected most frequently. All the contaminants recorded show higher accumulation in liver than other tissues. Levels of contaminants measured in the tissues of vulture are comparable with the levels documented in a number of avian species and are lower than those reported to have caused deleterious effects. Although no threat is expected from the current level of contamination, the presence of varying levels of contaminants and their additive or synergistic toxicity is a cause of concern to vultures. Values reported in this study can serve as guideline for future research. PMID:24288666

Converging evidence highlights that lipid metabolism plays a key role in ALS pathophysiology. Dyslipidemia has been described in ALS patients and may be protective but peripheral lipoprotein subclasses have never been studied. We collected sera from 30 ALS patients and 30 gender and age-matched controls. We analyzed 11 distinct lipoprotein subclasses by linear polyacrylamide gel electrophoresis (Lipoprint, Quantimetrix Corporation, USA). We also measured lipoprotein (a), apolipoprotein B, and apolipoprotein E levels. ALS patients had significant higher total cholesterol, HDL-cholesterol, and LDL-cholesterol levels than controls (p<0.0001, p=0.0007, and p=0.0065, respectively). The LDL-1 subfraction concentration was higher (1.03±0.41 vs. 0.71±0.28mmol/L; p=0.0006) and the IDL-B subfraction lower (6.5±2% vs. 8.0±2%; p=0.001) in ALS patients than controls. Our preliminary work confirmed the association between ALS and dyslipidemia. The low IDL-B levels may explain the hepatic steatosis frequently reported in ALS. The high levels of the cholesterol-rich LDL-1 subfraction is consistent with previously reported hypercholesterolemia. This study describes, for the first time, the distribution of serum lipoproteins in ALS patients, with low IDL-B and high LDL-1 subfraction level. Copyright © 2017 Elsevier B.V. All rights reserved.

Transcatheter aortic valve replacement (TAVR) requires large calibre catheters and is therefore associated with increased vascular complications. The aim of this study was to illustrate the impact of the different definitions of major vascular complications on their incidence and to underscore the importance of uniform reporting. We pooled dedicated databases of consecutive patients undergoing TAVR from two tertiary care facilities and looked for the incidence of major vascular complications using various previously reported definitions. The level of agreement (Kappa statistic) between the respective definitions and the Valve Academic Research Consortium (VARC) consensus definition of vascular complications was assessed. A total of 345 consecutive patients underwent transfemoral TAVR and were included in this analysis. A completely percutaneous access and closure technique was applied in 96% of cases. Arterial sheath size ranged between 18 and 24 Fr, the majority being 18 Fr (60%). Procedural success was reached in 94.5%. Depending on the definition used, major vascular complications occurred in 5.2-15.9% of patients. According to the VARC definitions, the rate of major and minor vascular complications was 9.0% and 9.6%, respectively. Major vascular complications according to VARC criteria demonstrated at least a substantial level of agreement with the SOURCE registry (k 0.80), the UK registry (k 0.82) the Italian registry (k 0.72) and "FRANCE" registry (k 0.70) definitions, compared to a moderate level of agreement with the definitions used in the German registry ( 0.47) and the 18 Fr Safety and Efficacy study (k 0.42). Minor complications according to VARC demonstrated a moderate agreement only with vascular complications using the German registry definition (k 0.54). Non-uniformity in how vascular complications are defined precludes any reliable comparison between previously reported TAVR registries. The VARC consensus document offers standardised endpoint definitions and should be universally adopted to obtain better insights into global TAVR experience.

Teachers have been shown to have high levels of stress and common mental disorder, but few studies have examined which factors within the school environment are associated with poor teacher mental health. Teachers (n=555) in 8 schools completed self-report questionnaires. Levels of teacher wellbeing (Warwick Edinburgh Mental Wellbeing Scale-WEMWBS) and depressive symptoms (Patient Health Questionnaire-PHQ-9) were measured and associations between these measures and school-related factors were examined using multilevel multivariable regression models. The mean (SD) teacher wellbeing score (47.2 (8.8)) was lower than reported in working population samples, and 19.4% had evidence of moderate to severe depressive symptoms (PHQ-9 scores >10). Feeling unable to talk to a colleague when feeling stressed or down, dissatisfaction with work and high presenteeism were all strongly associated with both poor wellbeing (beta coefficients ranged from -4.65 [-6.04, -3.28] to -3.39 [-5.48, -1.31]) and depressive symptoms (ORs ranged from 2.44 [1.41, 4.19] to 3.31 [1.70, 6.45]). Stress at work and recent change in school governance were also associated with poor wellbeing (beta coefficients=-4.22 [-5.95, -2.48] and -2.17 [-3.58, -0.77] respectively), while sickness absence and low student attendance were associated with depressive symptoms (ORs=2.14 [1.24, 3.67] and 1.93 [1.06, 6.45] respectively). i) This was a cross-sectional study; causal associations cannot be identified ii) several of the measures were self-report iii) the small number of schools reduced study power for the school-level variables Wellbeing is low and depressive symptoms high amongst teachers. Interventions aimed at improving their mental health might focus on reducing work related stress, and increasing the support available to them. Copyright © 2015 The Authors.

Significant advances in our understanding of the biological processes involved in tooth development and repair at the cellular and molecular levels have underpinned the newly emerging area of regenerative endodontics. Development of treatment protocols based on exploiting the natural wound healing properties of the dental pulp and applying tissue engineering principles has allowed reporting of case series showing preservation of tissue vitality and apexogenesis. To review current case series reporting regenerative endodontics. Current treatment approaches tend to stimulate more reparative than regenerative responses in respect of the new tissue generated, which often does not closely resemble the physiological structure of dentine-pulp. However, despite these biological limitations, such techniques appear to offer significant promise for improved treatment outcomes. Improved biological outcomes will likely emerge from the many experimental studies being reported and will further contribute to improvements in clinical treatment protocols.

Accuracy of indexing coverage information as reported by serials sources.

This article reports on the accuracy of indexing service coverage information listed in three serials sources: Ulrich's International Periodicals Directory, SERLINE, and The Serials Directory. The titles studied were randomly selected journals that began publication in either 1981 or 1986. Aggregate results reveal that these serials sources perform at 92%, 97%, and 95% levels of accuracy respectively. When the results are analyzed by specific indexing services by year, the performance scores ranged from 80% to 100%. All three serials sources tend to underreport index coverage. The author advances five recommendations for improving index coverage accuracy and four specific proposals for future research. The results suggest that, for the immediate future, librarians should treat index coverage information reported in these three serials sources with some skepticism. PMID:8251971

To assess the policies and programs on the capacity of prevention and control regarding non-communicable diseases (NCDs) at the Centers for Disease Control and Prevention (CDCs) at all levels and grass roots health care institutions, in China. On-line questionnaire survey was adopted by 3 352 CDCs at provincial, city and county levels and 1 200 grass roots health care institutions. 1) On policies: 75.0% of the provincial governments provided special funding for chronic disease prevention and control, whereas 19.7% city government and 11.3% county government did so. 2) Infrastructure:only 7.1% county level CDCs reported having a department taking care of NCD prevention and control. 8 263 staff members worked on NCDs prevention and control, accounting for 4.2% of all the CDCs' personnel. 40.2% CDCs had special funding used for NCDs prevention and control. 3)Capacity on training and guidance:among all the CDCs, 96.9% at provincial level, 50.3% at city level and 42.1% at county level had organized training on NCDs prevention and control. Only 48.3% of the CDCs at county level provided technical guidance for grass-roots health care institutions. 4) Capacities regarding cooperation and participation: 20.2% of the CDCs had experience in collaborating with mass media. 5) Surveillance capacity: 64.6% of the CDCs at county level implemented death registration, compare to less than 30.0% of CDCs at county level implemented surveillance programs on major NCDs and related risk factors. In the grass roots health care institutions, 18.6% implemented new stroke case reporting system but only 3.0% implemented program on myocardial infarction case reporting. 6) Intervention and management capacity: 36.1% and 32.2% of the CDCs conducted individualized intervention on hypertension and diabetes, while less than another 20% intervened into other NCDs and risk factors. More than 50% of the grass roots health care institutions carried follow-up survey on hypertension and diabetes. Rates on hypertension and diabetes patient management were 12.0% and 7.9% , with rates on standard management as 73.8% and 80.1% and on control as 48.7% and 50.0%, respectively. 7) Capacity on Assessment: 13.3% of the CDCs or health administrations carried out evaluation programs related to the responses on NCDs in their respective jurisdiction. 8) On scientific research: the capacity on scientific research among provincial CDCs was apparently higher than that at the city or county level CDCs. Policies for NCDs prevention and control need to be improved. We noticed that there had been a huge gap between county level and provincial/city level CDCs on capacities related to NCDs prevention and control. At the grass-roots health care institutions, both prevention and control programs on chronic diseases did not seem to be effective.

The present study was undertaken to determine the relationship between fluoride in water, urine and serum and dental fluorosis. The fluoride level in water and urine were measured spectrophotometrically by using acid zirconyl and SPADNS reagents, while the fluoride level in serum was determined by ion selective electrode meter. Dental fluorosis survey was conducted with the help of Performa prescribed by Rajiv Gandhi Drinking Water Mission and the use of Tooth Surface Index for Fluorosis. Mean fluoride values in water samples of Jhajjar City and Dadanpur and Dariyapur villages of Jhajjar District were measured to be 2.17 (range from 1.92 to 2.60 mg/L), 2.81 (range from 2.53 to 3.14 mg/L) and 2.22 mg/L (range from 1.63 to 3.33 mg/L), respectively. The mean fluoride values in the urine samples of children were found to be 1.51 (range from 0.05 to 2.64 mg/L), 1.71 (range from 0.69 to 2.80 mg/L) and 1.45 mg/L (range from 0.31 to 2.50 mg/L) at Jhajjar City and Dadanpur and Dariyapur sites, respectively. Serum fluoride was detected in the blood samples of children, who have high urinary fluoride at these three sites. The mean serum fluoride level was reported to be 0.15, 0.34 and 0.17 mg/L, respectively. A total of 842 children were also analyzed for dental fluorosis. The mean values of fluorosis-affected children in Jhajjar, Dadanpur and Dariyapur were 51.90, 94.63 and 36.84 %, respectively. A significantly positive correlation between water, urine, serum fluoride concentration and fluorosis was seen.

Reported salt levels in whole-muscle cured meat products differ substantially within and among European countries, providing substantial scope for salt reduction across this sector. The objective of this study was to identify the minimum acceptable salt levels in typical whole-muscle cured products in terms of physicochemical, microbial and sensorial properties. Salt levels in a small selection of commercial Irish meat products were determined to establish a baseline for reduction. Subsequently, eight different back bacon rasher and cooked ham products were produced with varying levels of salt: 2.9%, 2.5%, 2% and 1.5% for bacon, and 2%, 1.6%, 1.0% and 0.8% for ham. Salt reduction produced products with significantly harder texture and higher microbial counts, with no difference in the colour and affecting the sensory properties. Nonetheless, salt reduction proved to be feasible to levels of 34% and 19% in bacon and ham products, respectively, compared to baseline. Copyright © 2018 Elsevier Ltd. All rights reserved.

Demographic characteristics and clinical information including age, sex, educational level, marital status, job status, age at disease onset, oral symptoms, and triggers were collected via questionnaire interviews. To assess pain intensity the visual analogue scale (VAS) was administered. Descriptive statistics were collected, and Pearson Chi-square tests, Kruskal-Wallis nonparametric tests and the Spearman bivariate correlation were performed. The mean age was 61.17 (±11.75, female/male ratio = 3:1). The mean age at disease onset was 56.75 (±12.01). A low educational level (8.57 ± 4.95) and 80% of unemployment were found. Job status and age at disease onset correlated with the VAS scale (P = 0.019 and P = 0.015, respectively). Tongue morphology changes, taste disturbances, and intraoral foreign body sensation have a significant dependence on gender (P = 0.049, 0.001, and 0.045, respectively); intraoral foreign body sensation has a significant dependence on marital status (P = 0.033); taste disturbances have a significant dependence on job status. (P = 0.049); xerostomia has a significant dependence on age (P = 0.039); and tongue color changes and a bitter taste have a significant dependence on educational level (P = 0.040 and 0.022, respectively). Marital status and educational level have a significant dependence on the triggers (P = 0.036 and 0.049, respectively). The prevalence of BMS is higher in women, and in married, unemployed, and less highly educated patients. Burning is the most frequent symptom while stressful life events are the most frequent trigger reported. Wiley Periodicals, Inc.

Level I trauma centers often exist within safety-net hospitals (SNHs), facilities servicing high proportions of low-income and uninsured patients. Given the current health care funding environment, trauma centers within SNHs may be at particular risk. Using California as a model, we hypothesized that SNHs with trauma centers vary in terms of financial stability. We performed a retrospective cohort study using data from publicly available financial disclosure reports from California's Office of Statewide Health Planning and Development. Safety-net hospitals were identified from the California Association of Public Hospitals and Health Systems. The primary outcomes metric for financial performance was operating margin. California hospitals with Level I trauma centers were analyzed (11 SNH sites, 2 non SNH). The SNHs did not behave uniformly, and were clustered into county-owned SNHs (36%, n = 4) and nonprofit-owned SNHs (64%, n = 7). Mean operating margins for county SNHs, nonprofit SNHs, and non SNHs were -16.5%, 8.4%, and 9.5%, respectively (p < 0.001). From 2010 to 2015, operating margins improved for all hospitals, partly due to increases in the percent of insured patients and changes in payer mix. Nonprofit SNHs had a payer mix similar to that of non SNHs; county SNHs had the highest proportions of MediCal (California Medicaid) (45% vs 36% vs 12%, respectively, p < 0.001) and uninsured patients (17% vs 5% vs 0%, respectively, p < 0.001) compared with nonprofit SNHs and non SNHs, respectively. The majority (85%) of Level I trauma centers are within SNHs, whose financial stability is highly variable. A group of SNHs rely on infusions of government funds and are therefore susceptible to changes in policy. These findings suggest deliberate funding efforts are critical to protect the health of the US academic trauma system. Copyright © 2018 American College of Surgeons. Published by Elsevier Inc.

This study evaluated the survival outcome, pattern of failure and prognostic factors in cervix uteri cancer patients. We reviewed the data of 60 patients with stages IB-IVA cancer who were treated between January 2004 and December 2010. Most patients (n = 50; 83%) had squamous cell carcinoma. Stage IIB was the most common presentation (n = 41; 68%). Forty-seven patients (78%) received Cisplatin concurrent with radiotherapy (CRT). The 2- and 4-year overall survival (OS) was 82% and 79%, respectively. Prolongation of the overall treatment time (OAT) for greater than 56 days, advanced stage and pretreatment hemoglobin (Hb) levels (<10 g/dL) negatively predicted OS (P = 0.039, P = 0.044 and P = 0.008, respectively). The 2- and 4-year disease-free survival (DFS) rates were 80% and 69%, respectively. Vaginal infiltration and brachytherapy (orthogonal versus CT-based planning) were significant factors for the prediction of relapse (P = 0.048 and P = 0.049, respectively). The 2- and 4-year loco-regional control (LRC) rates were 78% and 70%, respectively, and the distant metastasis-free survival (DMFS) rates were 82% and 79%, respectively. Vaginal infiltration was the only negative predictive factor for LRC (P = 0.045), and pathological tumor grade was the only factor indicative of distant metastases (P = 0.037). Grade 3 or 4 late rectal reactions were reported in two patients (3%), and no patients developed grade 3 or 4 urinary reactions. The treatment results in our cervix uteri cancer patients and the prognostic factors are comparable to those of previous reports. Orthogonal brachytherapy planning and vaginal infiltration negatively predicted relapse. © 2016 John Wiley & Sons Australia, Ltd.

In some epidemiological studies, self-reported height and weight are often used to save time and money. Self-reported height and weight are commonly used to assess the prevalence of obesity. The aim of this study was to assess the differences between self-reported and measured height and weight in adult men, and to determine how the accuracy of self-reported data depended on age and education. The prevalence of obesity was also calculated based both on self-reported and measured data. Data were collected during two population studies carried out in Wroclaw in 2010. One study included 1,194 19-year-old males who reported for the health examination mandated by the National Conscription Board (younger group). The other group included 355 men between 35 and 80 years old who reported for a ten-year follow-up (older group). Data were analyzed separately for both age groups. Both younger and older subjects overestimated their height by 1.4 cm and 1.0 cm (1.4 cm, 95 % CI: 1.26, 1.51, and 1.0 cm, 95 % CI: 0.85, 1.26, respectively). On average, younger subjects overestimated their weight by 0.7 kilograms (95 % CI: 0.55, 0.92), whereas older subjects underestimated their weight by 0.9 kilograms (95 % CI: -1.15, -0.48). The lower the level of education, the more the subjects overestimated their height. Adult men systematically overestimate their height and underestimate their weight. The magnitude of the inaccuracy depends on level of education. When self-reported data are used, the prevalence of obesity is generally underestimated. Using self-reported data to calculate BMI can lead to a substantial underestimation of the proportion of underweight and obese individuals in a population. Finally, using self-reported values for height in studies on social inequality may lead to false conclusions.

This paper reports a study of the task partitioning observed in the ponerine ant Ectatomma ruidum, where prey-foraging behaviour can be subdivided into two categories: stinging and transporting. Stingers kill live prey and transporters carry prey corpses back to the nest. Stinging and transporting behaviours are released by certain stimuli through response thresholds; the respective stimuli for stinging and transporting appear to be the number of live prey and the number of prey corpses. A response threshold model, the parameters of which are all measured empirically, reproduces a set of non-trivial colony-level dynamical patterns observed in the experiments. This combination of modelling and empirical work connects explicitly the level of individual behaviour with colony-level patterns of work organization. Copyright 2002 Elsevier Science Ltd.

Objective To test whether public reporting in the setting of postacute care in nursing homes results in changes in patient sorting. Data Sources/Study Setting All postacute care admissions from 2001 to 2003 in the nursing home Minimum Data Set. Study Design We test changes in patient sorting (or the changes in the illness severity of patients going to high- versus low-scoring facilities) when public reporting was initiated in nursing homes in 2002. We test for changes in sorting with respect to pain, delirium, and walking and then examine the potential roles of cream skimming and downcoding in changes in patient sorting. We use a difference-in-differences framework, taking advantage of the variation in the launch of public reporting in pilot and nonpilot states, to control for underlying trends in patient sorting. Principal Findings There was a significant change in patient sorting with respect to pain after public reporting was initiated, with high-risk patients being more likely to go to high-scoring facilities and low-risk patients more likely to go to low-scoring facilities. There was also an overall decrease in patient risk of pain with the launch of public reporting, which may be consistent with changes in documentation of pain levels (or downcoding). There was no significant change in sorting for delirium or walking. Conclusions Public reporting of nursing home quality improves matching of high-risk patients to high-quality facilities. However, efforts should be made to reduce the incentives for downcoding by nursing facilities. PMID:21105869

Rice bran oil and oryzanol reduce plasma lipid and lipoprotein cholesterol concentrations and aortic cholesterol ester accumulation to a greater extent than ferulic acid in hypercholesterolemic hamsters.

Our laboratory has reported that the hypolipidemic effect of rice bran oil (RBO) is not entirely explained by its fatty acid composition. Because RBO has a greater content of the unsaponifiables, which also lower cholesterol compared to most vegetable oils, we wanted to know whether oryzanol or ferulic acid, two major unsaponifiables in RBO, has a greater cholesterol-lowering activity. Forty-eight F(1)B Golden Syrian hamsters (Mesocricetus auratus) (BioBreeders, Watertown, MA) were group housed (three per cage) in cages with bedding in an air-conditioned facility maintained on a 12-h light/dark cycle. The hamsters were fed a chow-based hypercholesterolemic diet (HCD) containing 10% coconut oil and 0.1% cholesterol for 2 weeks, at which time they were bled after an overnight fast (16 h) and segregated into 4 groups of 12 with similar plasma cholesterol concentrations. Group 1 (control) continued on the HCD, group 2 was fed the HCD containing 10% RBO in place of coconut oil, group 3 was fed the HCD plus 0.5% ferulic acid and group 4 was fed the HCD plus 0.5% oryzanol for an additional 10 weeks. After 10 weeks on the diets, plasma total cholesterol (TC) and non-high-density lipoprotein cholesterol (HDL-C) (very low- and low-density lipoprotein) concentrations were significantly lower in the RBO (-64% and -70%, respectively), the ferulic acid (-22% and -24%, respectively) and the oryzanol (-70% and -77%, respectively) diets compared to control. Plasma TC and non-HDL-C concentrations were also significantly lower in the RBO (-53% and -61%, respectively) and oryzanol (-61% and -70%, respectively) diets compared to the ferulic acid. Compared to control and ferulic acid, plasma HDL-C concentrations were significantly higher in the RBO (10% and 20%, respectively) and oryzanol (13% and 24%, respectively) diets. The ferulic acid diet had significantly lower plasma HDL-C concentrations compared to the control (-9%). The RBO and oryzanol diets were significantly lower for plasma triglyceride concentrations compared to the control (-53% and -65%, respectively) and ferulic acid (-47% and -60%, respectively) diets. Hamsters fed the control and ferulic acid diets had significantly higher plasma vitamin E concentrations compared to the RBO (201% and 161%, respectively) and oryzanol (548% and 462%, respectively) diets; the ferulic acid and oryzanol diets had significantly lower plasma lipid hydroperoxide levels than the control (-57% and -46%, respectively) diet. The oryzanol-fed hamsters excreted significantly more coprostenol and cholesterol in their feces than the ferulic acid (127% and 120%, respectively) diet. The control diet had significantly greater aortic TC and FC accumulation compared to the RBO (115% and 89%, respectively), ferulic acid (48% and 58%, respectively) and the oryzanol (74% and 70%, respectively) diets. However, only the RBO and oryzanol diets had significantly lower aortic cholesterol ester accumulation compared to the control (-73% and -46%, respectively) diet. The present study suggests that at equal dietary levels, oryzanol has a greater effect on lowering plasma non-HDL-C levels and raising plasma HDL-C than ferulic acid, possibly through a greater extent to increase fecal excretion of cholesterol and its metabolites. However, ferulic acid may have a greater antioxidant capacity via its ability to maintain serum vitamin E levels compared to RBO and oryzanol. Thus, both oryzanol and ferulic acid may exert similar antiatherogenic properties, but through different mechanisms.

A survey of chloropropanols in soy sauce and some selected foods in China is reported. Thirty-seven traditionally brewed soy sauce samples contained 3-MCPD below the EC maximum limit (ML) of 0.02 mg kg(-1). All soy sauce samples (629) from retailers contained levels of 3-MCPD ranging between <0.005 (LOQ) and 189 mg kg(-1), and only 12.2% had levels in excess of the Chinese ML of 1.0 mg kg(-1) for acid hydrolyzed vegetable protein (acid HVP). This indicates that the necessary processing changes have been made to decrease levels of chloropropanols in soy sauce. 2-Monochloropropane-1,3-diol (2-MCPD), 1,3-dichloro-2-propanol (1,3-DCP) and 2,3-dichloro-1-propanol (2,3-DCP) were detected in 48.1 19.1 and 3.78% of the soy sauce samples, respectively; the highest levels being 20.3, 8.26 and 0.50 mg kg(-1), respectively. A good linear correlation was found between the amount of 3-MCPD and 2-MCPD, with the level of 3-MCPD being generally higher than that of other chloropropanols for the same soy sauce. Acid HVP contained 3-MCPD at a level of 0.010-117.7 mg kg(-1) (on a liquid basis) and 80% of samples contained levels exceeding 1.0 mg kg(-1). In some other foods investigated, relatively high levels of 3-MCPD were found in soy sauce powder, oyster sauce, beef products, instant noodle spices and health foods, ranging from 0.029 to 13.64 mg kg(-1). It is concluded that abnormal levels of 3-MCPD in soy sauce or other foods produced in China may result from acid hydrolysis or the addition of the contaminated acid HVP.

The U.S. Geological Survey, in support of the U.S. Department of Energy, Yucca Mountain Site Characterization Project, collects, compiles, and summarizes hydrologic data in the Yucca Mountain region. The data are collected to allow assessments of ground-water resources during studies to determine the potential suitability of Yucca Mountain for storing high-level nuclear waste. Data on ground-water levels at 34 wells and a fissure (Devils Hole), ground-water discharge at 5 springs and a flowing well, and total reported ground-water withdrawals within Crater Flat, Jackass Flats, Mercury Valley, and the Amargosa Desert are presented for calendar year 1999. Data collected prior to 1999 are graphically presented and data collected by other agencies (or as part of other Geological Survey programs) are included to further indicate variations of ground-water levels, discharges, and withdrawals through time. A statistical summary of ground-water levels at seven wells in Jackass Flats is presented to indicate potential effects of ground-water withdrawals associated with U.S. Department of Energy activities near Yucca Mountain. The statistical summary includes the number of measurements, the maximum, minimum, and median water-level altitudes, and the average deviation of measured water-level altitudes for selected baseline periods and for calendar years 1992-99. At two water-supply wells median water levels for calendar year 1999 were unchanged from their respective baseline periods. At a nearby observation well, the 1999 median water level was slightly lower (0.1 foot) than its baseline period. At the remaining four wells in Jackass Flats, median water levels for 1999 were slightly higher (0.2 foot to 1.6 feet) than for their respective baseline periods.

Although physician-patient communication and health literacy (HL) have been studied in diverse patient groups, there has been little focus on trauma patients. A quality improvement project was undertaken at our Level I trauma center to improve patient perception of physician-patient communication, with consideration of the effect of HL. We report the first phase of this project, namely the reference level of satisfaction with physician-patient communication as measured by levels of interpersonal care among patients at an urban Level I trauma center. Level I trauma center patients were interviewed during hospitalization (August 2016 to January 2017). Short Assessment of Health Literacy tool was used to stratify subjects by deficient versus adequate HL. Interpersonal Processes of Care survey was administered to assess perception of physician-patient communication. This survey allowed patients to rate physician-patient interaction across six domains: "clarity," "elicited concerns," "explained results," "worked together (on decision making)," "compassion and respect," and "lack of discrimination by race/ethnicity." Each is scored on a five-point scale. Frequencies of "top-box" (5/5) scores were compared for significance (p < 0.05) between HL-deficient and HL-adequate patients. One hundred ninety-nine patients participated. Average age was 42 years, 33% female. Forty-nine (25%) patients had deficient HL. The majority of patients in both groups rated communication below 5/5 across all domains except "compassion and respect" and "lack of discrimination by race/ethnicity." Health literacy-deficient patients were consistently less likely to give physicians top-box scores, most notably in the "elicited concerns" domain (35% vs. 54%, p = 0.012). Health literacy-deficient patients appear relatively less satisfied with physician communication, particularly with respect to perceiving that their concerns are being heard. Overall, however, the majority of patients in both groups were unlikely to score physician communication in the "top box." Efforts to improve physician-trauma patient communication are warranted, with attention directed toward meeting the needs of HL-deficient patients. Prognostic/Epidemiologic, level I.

Background/Aims Mercury (Hg) is a potent toxicant of concern to the general public. Recent studies suggest that several genes that mediate Hg metabolism are polymorphic. We hypothesize that single nucleotide polymorphisms (SNPs) in such genes may underline inter-individual differences in exposure biomarker concentrations. Methods Dental professionals were recruited during the American Dental Association (ADA) 2012 Annual Meeting. Samples of hair, blood, and urine were collected for quantifying Hg levels and genotyping (88 SNPs in classes relevant to Hg toxicokinetics including glutathione metabolism, selenoproteins, metallothioneins, and xenobiotic transporters). Questionnaires were administrated to obtain information on demographics and sources of Hg exposure (e.g., fish consumption and use of dental amalgam). Here, we report results for 380 participants with complete genotype and Hg biomarker datasets. ANOVA and linear regressions were used for statistical analysis. Results Mean (geometric) Hg levels in hair (hHg), blood (bHg), urine (uHg), and the average estimated Hg intake from fish were 0.62μg/g, 3.75μg/L, 1.32μg/L, and 0.12μg/kg body weight/day, respectively. Out of 88 SNPs successfully genotyped, Hg biomarker levels differed by genotype for 25 SNPs, one of which remained significant following Bonferroni correction in ANOVA. When the associations between sources of Hg exposure and SNPs were analyzed with respect to Hg biomarker concentrations, 38 SNPs had significant main effects and/or gene-Hg exposure source interactions. Twenty-five, 23, and four SNPs showed significant main effects and/or interactions for hHg, bHg, and uHg levels, respectively (p<0.05), and six SNPs (in GCLC, MT1M, MT4, ATP7B, and BDNF) remained significant following Bonferroni correction. Conclusion The findings suggest that polymorphisms in environmentally-responsive genes can influence Hg biomarker levels. Hence, consideration of such gene-environment factors may improve the ability to assess the health risks of Hg more precisely. PMID:26673400

To investigate the knowledge, attitudes and behaviour of Greek adults towards salt as well as their differences with respect to gender, age and level of education. Cross-sectional, observational survey. Voluntary participation to a telephone interview, using a seventeen-item questionnaire. Greek adults aged over 25 years (n 3609), nationally representative according to age, gender and geographical distribution of the Greek population, were interviewed. More women of all age groups compared with men reported adding salt during cooking (P < 0·001), while less reported adding salt on the plate (P < 0·001). Also, more women believed that salt added during cooking was the main source of salt in the diet (P < 0·001). Participants aged 25-34, 35-44 and 45-54 years old had better knowledge of the harmful effects of salt on health compared with the 55+ years age group (P = 0·002, P = 0·001, P < 0·001, respectively); respondents in the aforementioned age groups also knew that children should consume less salt than adults compared with 55+ years age group (P = 0·004, P < 0·001, P < 0·001, respectively). Respondents with secondary and higher educational status were more likely to avoid consumption of processed foods (P < 0·001) and to check the nutrition information on food packaging as compared with respondents having basic education status (P < 0·001). Awareness needs to be raised regarding salt recommendations for adults and children, sources of sodium in the diet and adding less salt during cooking, as well as reading food labels. Future campaigns for salt reduction should consider gender, age and level of education differences regarding knowledge, attitudes and behaviour towards salt.

There is a dearth of research focusing on sex work in exotic dance clubs. We conducted a cross-sectional study to examine the prevalence and correlates of crack cocaine smoking among a sample of exotic dancers. The "block," a historical red-light district in downtown Baltimore, MD, is comprised of 30 adult-entertainment establishments. Between 01/09 and 08/09, we conducted a survey with exotic dancers (N=98). The survey explored demographic, and drug and sexual/drug risk behaviors. Bivariate and multivariate analysis was conducted using Poisson regression with robust variance estimates to examine correlates of current crack smoking. Crack cocaine smokers compared to non-crack cocaine smokers were significantly more likely to report: older age (29 vs. 23 years, respectively, p<0.0001); being White (79% vs. 50%, respectively, p=0.008); having been arrested (93% vs. 67%, respectively, p=0.008); daily alcohol consumption (36% vs. 17%, p=0.047); current heroin injection (57% vs. 13%, p<0.001); and current sex exchange (79% vs. 30%, p<0.001). In the presence of other variables, crack cocaine smokers compared to non-crack cocaine smokers were significantly older, more likely to report current heroin injection, and more likely to report current sex exchange. We found high levels of drug use and sexual risk behaviors as well as a number of risks behaviors associated with crack cocaine smoking among this very under-studied population. Targeted interventions are greatly needed. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.
