Survivors of childhood cancer are at risk for a variety of treatment-related late effects and require lifelong individualized surveillance for early detection of late effects. This study assessed knowledge and perceptions of late effects risk before and after a survivor clinic visit. Young adult survivors (≥ 16 years) and parents of child survivors (< 16 years) were recruited prior to initial visit to a cancer survivor program. Sixty-five participants completed a baseline survey and 50 completed both a baseline and follow-up survey. Participants were found to have a low perceived likelihood of developing a late effect of cancer therapy and many incorrect perceptions of risk for individual late effects. Low knowledge before clinic (odds ratio = 9.6; 95% confidence interval, 1.7-92.8; P = .02) and low perceived likelihood of developing a late effect (odds ratio = 18.7; 95% confidence interval, 2.7-242.3; P = .01) were found to predict low knowledge of late effect risk at follow-up. This suggests that perceived likelihood of developing a late effect is an important factor in the individuals' ability to learn about their risk and should be addressed before initiation of education. © 2014 by Association of Pediatric Hematology/Oncology Nurses.

While Australians are searching the internet for third molar (TM) information, the usefulness of online sources may be questioned due to quality variation. This study explored: (i) internet use, online information-seeking behaviour among TM patients attending public dental services; and (ii) whether patients' TM knowledge scores are associated with the level of internet use and eHealth Literacy Scale (eHEALS) scores. Baseline survey data from the 'Engaging Patients in Decision-Making' study were used. Variables included: sociodemographics, internet access status, online information-seeking behaviour, eHEALS, the Control Preferences Scale (CPS) and TM knowledge. Participants (N = 165) were mainly female (73.8%), aged 19-25 years (42.4%) and had 'secondary school or less' education (58.4%). A majority (N = 79, 52.7%) had sought online dental information which was associated with active decisional control preference (odds ratio = 3.1, P = 0.034) and higher educational attainment (odds ratio = 2.7, P = 0.040). TM knowledge scores were not associated with either the level of internet use (F (2,152) = 2.1, P = 0.094, χ 2 = 0.0310) or the eHEALS scores (r = 0.147, P = 0.335). 'The internet-prepared patient' phenomena exists among public TM patients and was explained by preference for involvement in decision-making. However, internet use was not associated with better TM knowledge. Providing TM patients with internet guidance may be an opportunity to improve TM knowledge. © 2017 Australian Dental Association.

While associations between secondhand smoke and a few birth defects (namely, oral clefts and neural tube defects) have been noted in the scientific literature, to our knowledge, there is no single or comprehensive source of population-based information on its associations with a range of birth defects among nonsmoking mothers. We utilized data from the National Birth Defects Prevention Study, a large population-based multisite case-control study, to examine associations between maternal reports of periconceptional exposure to secondhand smoke in the household or workplace/school and major birth defects. The multisite National Birth Defects Prevention Study is the largest case-control study of birth defects to date in the United States. We selected cases from birth defect groups having >100 total cases, as well as all nonmalformed controls (10,200), from delivery years 1997 through 2009; 44 birth defects were examined. After excluding cases and controls from multiple births and whose mothers reported active smoking or pregestational diabetes, we analyzed data on periconceptional secondhand smoke exposure-encompassing the period 1 month prior to conception through the first trimester. For the birth defect craniosynostosis, we additionally examined the effect of exposure in the second and third trimesters as well due to the potential sensitivity to teratogens for this defect throughout pregnancy. Covariates included in all final models of birth defects with ≥5 exposed mothers were study site, previous live births, time between estimated date of delivery and interview date, maternal age at estimated date of delivery, race/ethnicity, education, body mass index, nativity, household income divided by number of people supported by this income, periconceptional alcohol consumption, and folic acid supplementation. For each birth defect examined, we used logistic regression analyses to estimate both crude and adjusted odds ratios and 95% confidence intervals for both isolated and total case groups for various sources of exposure (household only; workplace/school only; household and workplace/school; household or workplace/school). The prevalence of secondhand smoke exposure only across all sources ranged from 12.9-27.8% for cases and 14.5-15.8% for controls. The adjusted odds ratios for any vs no secondhand smoke exposure in the household or workplace/school and isolated birth defects were significantly elevated for neural tube defects (anencephaly: adjusted odds ratio, 1.66; 95% confidence interval, 1.22-2.25; and spina bifida: adjusted odds ratio, 1.49; 95% confidence interval, 1.20-1.86); orofacial clefts (cleft lip without cleft palate: adjusted odds ratio, 1.41; 95% confidence interval, 1.10-1.81; cleft lip with or without cleft palate: adjusted odds ratio, 1.24; 95% confidence interval, 1.05-1.46; cleft palate alone: adjusted odds ratio, 1.31; 95% confidence interval, 1.06-1.63); bilateral renal agenesis (adjusted odds ratio, 1.99; 95% confidence interval, 1.05-3.75); amniotic band syndrome-limb body wall complex (adjusted odds ratio, 1.66; 95% confidence interval, 1.10-2.51); and atrial septal defects, secundum (adjusted odds ratio, 1.37; 95% confidence interval, 1.09-1.72). There were no significant inverse associations observed. Additional studies replicating the findings are needed to better understand the moderate positive associations observed between periconceptional secondhand smoke and several birth defects in this analysis. Increased odds ratios resulting from chance (eg, multiple comparisons) or recall bias cannot be ruled out. Copyright © 2016 Elsevier Inc. All rights reserved.

In Japan, comprehensive food education (shokuiku) programs are carried out with the aim of improving dietary practices and thereby reducing the incidence of lifestyle-related diseases, including dental caries. The purpose of this prospective cohort study was to investigate the association between knowledge about shokuiku and the increase in dental caries among Japanese university students who had attended a shokuiku program while in junior/senior high school. A total of 562 students volunteered to undergo oral examinations over a three-year follow-up period, during which the number of cases of dental caries were recorded. Additional information was collected using a questionnaire survey regarding knowledge about shokuiku, dietary habits, and oral health behaviors. In logistic regression analysis, males who lacked knowledge about shokuiku had significantly higher odds for dental caries than those who did not (odds ratio (OR), 2.00; 95% confidence interval (CI), 1.12-3.58; p = 0.019). On the other hand, among females, those who frequently consumed sugar-sweetened soft drinks had significantly higher odds for dental caries than those who did not (OR, 1.89; 95% CI, 1.05-3.42; p = 0.035). These results suggest that having no knowledge about shokuiku is associated with a risk of increase in dental caries in Japanese male university students.

Schistosomiasis is a highly prevalent parasitic disease in Senegal. The early symptoms are hematuria and dysuria. Children's comprehension of the disease is fundamental to preventing the infection. The aim of this study was to investigate the knowledge attitudes, and practices related to schistosomiasis among schoolchildren in 2 rural villages in Northern Senegal and to evaluate their impact on the disease. A cross-sectional study was conducted. Data about children's knowledge of schistosomiasis, behavior, and preventive measures were collected through a questionnaire. Questionnaire responses from 575 schoolchildren were analyzed. Correct answers about risky behavior for schistosomiasis were associated with early symptoms (P = 0.010). Wearing shoes and washing hands with soap were associated with not having hematuria and dysuria (P = 0.007 and 0.049, respectively). Playing in rivers was associated with the aforementioned symptoms (P < 0.001). Children who had good knowledge of schistosomiasis reportedly did not have symptoms (P = 0.002). A logistic regression model showed that female sex (odds ratio = 0.35; P = 0.01) and attending a primary school (odds ratio = 0.13; P < 0.001) were significant predictors of a lower risk of the early symptoms of urinary schistosomiasis. This study revealed that the level of knowledge among children in North Senegal about the causes, transmission, prevention, and treatment of schistosomiasis warrants implementing educational intervention.

Professional sport organizations in the United States have notable celebrity status, and several teams have used this "star power" to collaborate with local school districts toward the goal of affecting children's health. Program effectiveness is unknown due to the absence of comprehensive evaluations for these initiatives. The Memphis Grizzlies, the city's National Basketball Association franchise, launched "Get Fit with the Grizzlies," a 6-week, curricular addition focusing on nutrition and physical activity for the fourth and fifth grades in Memphis City Schools (MCS). The health-infused mini-unit was delivered by physical education teachers during their classes. The purpose of this study was to evaluate the "Get Fit" program effectiveness. Survey research was employed which measured health knowledge acquisition and health behavior change using a matched pre/posttest design in randomly chosen schools (n = 11) from all elementary schools in the MCS system (N = 110). The total number of matched pre/posttests (n = 888) equaled approximately 5% of the total fourth-/fifth-grade population. McNemar's test for significance (p < .05) was applied. Odds ratios were calculated for each question. Analyses confirmed that there was significant health knowledge acquisition (7 of 8 questions) with odds ratios confirming moderate to strong associations. Seven out of 10 health behavior change questions significantly improved after intervention, whereas odds ratios indicated a low level of association after intervention. This community-school-home initiative using a professional team's celebrity platform within a certain locale is largely overlooked by school districts and should be considered as a positive strategy to confront childhood obesity.

EHR based Genetic Testing Knowledge Base (iGTKB) Development

PubMed Central

2015-01-01

Background The gap between a large growing number of genetic tests and a suboptimal clinical workflow of incorporating these tests into regular clinical practice poses barriers to effective reliance on advanced genetic technologies to improve quality of healthcare. A promising solution to fill this gap is to develop an intelligent genetic test recommendation system that not only can provide a comprehensive view of genetic tests as education resources, but also can recommend the most appropriate genetic tests to patients based on clinical evidence. In this study, we developed an EHR based Genetic Testing Knowledge Base for Individualized Medicine (iGTKB). Methods We extracted genetic testing information and patient medical records from EHR systems at Mayo Clinic. Clinical features have been semi-automatically annotated from the clinical notes by applying a Natural Language Processing (NLP) tool, MedTagger suite. To prioritize clinical features for each genetic test, we compared odds ratio across four population groups. Genetic tests, genetic disorders and clinical features with their odds ratios have been applied to establish iGTKB, which is to be integrated into the Genetic Testing Ontology (GTO). Results Overall, there are five genetic tests operated with sample size greater than 100 in 2013 at Mayo Clinic. A total of 1,450 patients who was tested by one of the five genetic tests have been selected. We assembled 243 clinical features from the Human Phenotype Ontology (HPO) for these five genetic tests. There are 60 clinical features with at least one mention in clinical notes of patients taking the test. Twenty-eight clinical features with high odds ratio (greater than 1) have been selected as dominant features and deposited into iGTKB with their associated information about genetic tests and genetic disorders. Conclusions In this study, we developed an EHR based genetic testing knowledge base, iGTKB. iGTKB will be integrated into the GTO by providing relevant clinical evidence, and ultimately to support development of genetic testing recommendation system, iGenetics.

The purpose of this study was to identify and describe the knowledge and attitudes of cigarette smoking that are associated with smoking habits among young military conscripts in Taiwan. We conducted a cross-sectional survey of young conscripts in southern and eastern Taiwan between August 1 and December 31, 2001. We selected 3,249 young military conscripts who had served more than 1 month in the military, based on specific criteria. We used a standard structured questionnaire to collect information about the respondents' sociodemographic characteristics, lifestyle, knowledge, attitude, and cigarette smoking practices. Our findings showed that among smoking young military conscripts, knowledge about smoking was lower and attitudes toward smoking were more negative when compared with the non-smokers. Knowledge and attitudes about smoking varied with sociodemographic characteristics (age, education level, residential area) and lifestyle (cigarette smoking, betel nut chewing, alcohol drinking), all p < 0.05. Subjects with greater knowledge about smoking had a lower risk of smoking (odds ratio, 0.88; 95% confidence interval, 0.86-0.91). But this characteristic diminished after being adjusted for potential confounders. In addition, subjects with a higher attitude score about smoking had relatively lower risk for cigarette smoking when compared to those with a lower attitude score, even after adjusting for potential confounders (odds ratio, 0.93; 95% confidence interval, 0.91-0.94). Knowledge and attitudes about smoking are significantly associated with the status of cigarette smoking. These findings can help public health professionals develop effective policies and smoking prevention and cessation programs among young military conscripts in Taiwan. Copyright 2010 Elsevier.

Numerous studies have investigated the associations between methylenetetrahydrofolate reductase (MTHFR) gene C677T and A1298C polymorphisms and risk of recurrent pregnancy loss (RPL); however, the results remain controversial. The aim of this study is to drive a more precise estimation of association between MTHFR gene polymorphisms and risk of RPL. We searched PubMed, EMBASE, Cochrane library, Web of Science and China Knowledge Resource Integrated Database for papers on MTHFR gene C677T and A1298C polymorphisms and RPL risk. The pooled odds ratios (ORs) with 95 % confidence intervals (CIs) were used to assess the strength of association in the homozygous model, heterozygous model, dominant model, recessive model and an additive model. The software STATA (Version 13.0) was used for statistical analysis. Overall, 57 articles were included in the final meta-analysis. In maternal group the MTHFR C677T polymorphism showed pooled odds ratios for the homozygous comparison [OR = 2.285, 95 % CI (1.702, 3.067)] and the MTHFR A1298C polymorphism showed pooled odds ratios for recessive model [OR = 1.594, 95 % CI (1.136, 2.238)]. In fetal group the MTHFR C677T polymorphism showed pooled odds ratios for dominant model [OR = 1.037, 95 % CI (0.567, 1.894)] and the MTHFR A1298C polymorphism showed pooled odds ratios for dominant model [OR = 1.495, 95 % CI (1.102, 2.026)]. In summary, the results of our meta-analysis indicate that maternal and paternal MTHFR gene C677T and A1298C polymorphisms are associated with RPL. We also observed a significant association between fetal MTHFR A1298C polymorphism and RPL but not C677T.

ABO blood groups are associated with various diseases. A relationship between Achilles tendon ruptures and blood type O has been reported, although its pathogenesis was not clear. To the best of our knowledge, there is no published study describing the relationship between blood type and rotator cuff tendon tears. To determine whether patients with rotator cuff tear had a greater prevalence of blood type O than those without rotator cuff tear. A cross-sectional study. Research hospital outpatient evaluation. A total of 316 subjects with shoulder pain were included and divided into "tear" and "no-tear" groups according to ultrasonographic examination. ABO blood group, gender, dominant arm, smoking history, trauma history, and age were compared between the 2 groups and the odds ratios of these factors were evaluated by logistic regression. The tear group (38.6%) had more instances of blood type O than the healthy population (27.2%; P = .002). The adjusted odds ratio for rotator cuff tear for blood type O to non-O was 2.38 (95% confidence interval 1.28-4.42). The odds ratios for rotator cuff tears for smoking, major trauma history, minor trauma history, and age were 2.08, 3.11, 2.29, and 1.06, respectively. Patients with rotator cuff tears were more likely to have blood type O. The odds ratios of factors for rotator cuff tears were high in the following order: major trauma history, blood type O, minor trauma history, and age.

Health promotion intervention in schools is a useful strategy to improve students' health awareness. The purpose of this study was to assess the effect of eye health promotion interventions on eye health literacy in school children in Vietnam. A piloted questionnaire was administered to 300 children from five secondary schools in Ba Ria-Vung Tau, Vietnam at baseline and re-administered after the eye health promotion interventions. McNemar chi-square and logistic regression were used for statistical analysis. A total of 300 children aged 12-15 years (mean, 13.3 ± 1.3 years; 60% female) participated in the baseline survey. The participation rate in the post-health promotion survey was 94.7%. After the health promotion interventions, number of children who had correct eye health knowledge increased by 10-20% (60-75% to 70-95%), more children reported having had an eye examination (63.3% to 84.7%; p < 0.001) and more reported wearing spectacles (36.1% to 43.4%; p = 0.04). Children in urban schools were twice as likely to have improved knowledge of vision loss compared with children in rural schools (odds ratio, 2.1-4.1; p = 0.01 to p < 0.001). Children from rural schools had significantly higher odds of visiting doctor after the eye problems worsened (odds ratio, 4.5; p < 0.001). These results imply that eye health promotion interventions significantly improve eye health knowledge, attitudes and practices of school children. Additionally, participation of parents and teachers as change agents may further improve children's health literacy. © The Author 2017. Published by Oxford University Press. All rights reserved.

Patients with pre-injury coagulopathy have worse outcomes than those without coagulopathy. This article investigated the risk-adjusted effect of pre-injury coagulopathy on outcomes after splenic injuries. Review of the National Trauma Data Bank from 2007 to 2010 comparing mortality and complications between splenic injury patients with and without a pre-injury bleeding disorder. Of 58,896 patients, 2% had a bleeding disorder. Coagulopathic patients had higher odds of mortality (odds ratio, 1.3), sepsis (odds ratio, 2.0), acute respiratory distress syndrome (odds ratio, 2.6), acute renal failure (odds ratio, 1.5), cardiac arrest (odds ratio, 1.5), and overall complications (odds ratio, 2.4). The higher odds of myocardial infarction did not achieve statistical significance (odds ratio, 1.6). Pre-injury coagulopathy in patients with splenic injury has a negative impact on cardiac arrest, sepsis, acute respiratory distress syndrome, acute renal failure, and mortality. The higher likelihood of myocardial infarction did not reach statistical significance. Copyright © 2015 Elsevier Inc. All rights reserved.

The American Cancer Society (ACS) recommends men have the opportunity to make an informed decision about screening for prostate cancer (PCa). The ACS developed a unique decision aid (ACS-DA) for this purpose. However, to date, studies evaluating the efficacy of the ACS-DA are lacking. The authors evaluated the ACS-DA among a cohort of medically underserved men (MUM). A multiethnic cohort of MUM (n = 285) was prospectively included between June 2010 and December 2014. The ACS-DA was presented in a group format. Levels of knowledge on PCa were evaluated before and after the presentation. Participants' decisional conflict and thoughts about the presentation also were evaluated. Logistic regression analyses were performed to determine factors associated with having an adequate level of knowledge. Before receiving the ACS-DA, 33.1% of participants had adequate knowledge on PCa, and this increased to 77% after the DA (P < .0001). On multivariate analysis, higher education level (odds ratio, 11.19; P = .001) and history of another cancer (odds ratio, 7.45; P = .03) were associated with having adequate knowledge after receiving the DA. Levels of decisional conflict were low and were correlated with levels of knowledge after receiving the DA. The majority of men also rated the presentation as favorable and would recommend the ACS-DA to others. Use of the ACS-DA was feasible among MUM and led to increased PCa knowledge. This also correlated with low levels of decisional conflict. The ACS-DA presented to groups of men may serve as a feasible tool for informed decision making in a MUM population.

Purpose Diabetes mellitus is a growing global health problem that affects patients of all ages. Even though diabetes mellitus is recognized as a major chronic illness, adherence to antidiabetic medicines has often been found to be unsatisfactory. This study was conducted to assess adherence to medications and to identify factors that are associated with nonadherence in type 2 diabetes mellitus (T2DM) patients at Primary Health Clinics of the Ministry of Health in Malaysia. Materials and methods The cross-sectional survey was carried out among T2DM patients to assess adherence to medication in primary health clinics. Adherence was measured by using the Medication Compliance Questionnaire that consists of a total of seven questions. Other data, such as patient demographics, treatment, outcome, and comorbidities were also collected from patient medical records. Results A total of 557 patients were recruited in the study. Approximately 53% of patients in the study population were nonadherent. Logistic regression analysis was performed to predict the factors associated with nonadherence. Variables associated with nonadherence were age, odds ratio 0.967 (95% confidence interval [CI]: 0.948–0.986); medication knowledge, odds ratio 0.965 (95% CI: 0.946–0.984); and comorbidities, odds ratio 1.781 (95% CI: 1.064–2.981). Conclusion Adherence to medication in T2DM patients in the primary health clinics was found to be poor. This is a cause of concern, because nonadherence could lead to a worsening of disease. Improving medication knowledge by paying particular attention to different age groups and patients with comorbidities could help improve adherence. PMID:23814461

Errors in drug dosing lead to poor patient outcomes and are common in patients with chronic kidney disease (CKD). Because the majority of patients with CKD are being treated by physicians specializing in internal medicine, we studied the awareness and knowledge that internal medicine resident trainees (IMRTs) have regarding the correct dosage of commonly used analgesic and neuropsychotropic medications for patients with CKD. We surveyed 353 IMRTs about their awareness of whether a medication needs dose adjustment in patients with CKD and knowledge for medication adjustment by level of glomerular filtration rate. There were high percentages for lack of awareness and knowledge. For analgesics, this lack of awareness/knowledge was highest for acetaminophen (awareness 83.0%, knowledge 90.9%). For neuropsychotropics, this was highest for paroxetine (awareness 74.5%, knowledge 91.5%). Analyses for postgraduate year (PGY) -1 trainees and PGY-2 trainees for analgesics showed higher odds for lack of awareness for tramadol (PGY-1 odds ratio [OR] 2.37, 95% confidence interval [CI] 1.2-4.62, P < 0.05; PGY-2 OR 2.34, 95% CI 1.16-4.72, P < 0.05) and for lack of knowledge for meperedine (PGY-1 OR 4.01, 95% CI 1.81-8.89, P < 0.05; PGY-2 OR 3.30, 95% CI 1.44-7.59, P < 0.05). Nephrology residency rotation for the neuropsychotropic medication of gabapentin showed lower odds for both lack of awareness (OR 0.56, 95% CI 0.32-0.97, P < 0.05) and knowledge (OR 0.52, 95% CI 0.27-0.997, P < 0.05). Awareness and knowledge are poor among IMRTs for dose adjustments of analgesics and neuropsychotropic medication classes in patients with CKD. There should be a renewed focus during IMRTs' residency on additional nephrology exposure and formal didactic educational training to help them better manage complex treatment regimens to prevent medication dosing errors.

To analyse pharmacy customers' knowledge and information sources about side effects of medicines they purchased and factors associated with this knowledge. Cross-sectional survey and semi-structured interviews with customers of 52 randomly selected community pharmacies in Morelos state, Mexico. Customers were included if they were older than 18 years, bought at least one drug either with or without medical prescription, and agreed to take part in the survey. Data were analysed using a multinomial logistic regression model. A total of 1445 customers buying 1946 drugs were surveyed (age 42.9 +/- 15.7 years, 56.9% female); 627 (59%) of 1055 customers who purchased prescription-only medicines (POM) did so without a prescription. Of all customers interviewed, 172 (11.9%) affirmed that the bought medicine(s) could cause harm. Only half of those (87 or 6%) were able to identify correctly at least one side effect of the purchased medicines. The majority received the information about side effects from a physician. Customers in semirural areas knew less about side effects (odds ratio: 0.26; 95% CI: 0.11-0.61; P = 0.00); whereas customers buying medicines for chronic pain, hypertension or diabetes knew more (odds ratio 2.63; 95% CI: 1.44-4.80; P = 0.00). The overall majority of customers did not know that medicines they bought could be harmful. This is particularly alarming because they frequently used POM without consulting a physician.

Introduction In 2010, the Los Angeles County Department of Public Health launched a local sodium-reduction initiative to address the rising prevalence of high blood pressure (hypertension) and related cardiovascular conditions in the population. To inform this effort, we evaluated self-reported knowledge and health behaviors related to sodium intake among Los Angeles County residents. Methods We administered 3 cross-sectional Internet panel surveys on knowledge about dietary sodium to a sample of Los Angeles County adults, at intervals from December 2014 through August 2016. Multinomial and logistic regression models were constructed to describe associations between sodium knowledge and self-reported health behaviors. Results A total of 7,067 panel subjects clicked into the online survey, and 2,862 completed the survey (adjusted response rate = 40.5%). Only 102 respondents (3.6%) were able to accurately report the recommended milligrams of sodium that an average adult should consume daily (1,500 mg to 2300 mg). Knowing about daily sodium intake recommendations was associated with increased odds of using Nutrition Facts labels to make food purchase decisions (adjusted odds ratio [AOR], 3.48; 95% confidence interval [CI], 1.59–7.60) and with decreased odds of taking measures to prevent hypertension (AOR, 0.38; 95% CI, 0.19–0.74). Conclusions Los Angeles County residents had a limited knowledge of recommended daily sodium intake. Efforts to increase understanding of these recommendations may encourage wider engagement in healthy behaviors. Health agencies should integrate sodium reduction messages in their diet and nutrition educational efforts. PMID:29166247

Previous studies have revealed inequalities in stroke treatment based on demographics, hospital type, and region. We used the Swedish Stroke Register (Riksstroke) to test whether patient education level is associated with reperfusion (either or both of thrombolysis and thrombectomy) treatment. We included 85 885 patients with ischemic stroke aged 18 to 80 years registered in Riksstroke between 2003 and 2009. Education level was retrieved from Statistics Sweden, and thrombolysis, thrombectomy, patient, and hospital data were obtained from Riksstroke. We used multivariable logistic regression to analyze the association between reperfusion therapy and patient education. A total of 3649 (4.2%) of the patients received reperfusion therapy. University-educated patients were more likely to be treated (5.5%) than patients with secondary (4.6%) or primary education (3.6%; P<0.001). The inequality associated with education was still present after adjustment for patient characteristics; university education odds ratio, 1.14; 95% confidence interval, 1.03 to 1.26 and secondary education odds ratio, 1.08; 95% confidence interval, 1.00 to 1.17 compared with primary education. Higher hospital specialization level was also associated with higher reperfusion levels (P<0.001). In stratified multivariable analyses by hospital type, significant treatment differences by education level existed only among large nonuniversity hospitals (university education odds ratio, 1.20; 95% confidence interval, 1.04-1.40; secondary education odds ratio, 1.14; 95% confidence interval, 1.01-1.29). We demonstrated a social stratification in reperfusion, partly explained by patient characteristics and the local hospital specialization level. Further studies should address treatment delays, stroke knowledge, and means to improve reperfusion implementation in less specialized hospitals. © 2014 American Heart Association, Inc.

To investigate predictors of patients' preferences for participation in clinical decision-making in inpatient nursing care. Patient participation in decision-making in nursing care is regarded as a prerequisite for good clinical practice regarding the person's autonomy and integrity. A cross-sectional survey of 428 persons, newly discharged from inpatient care. The survey was conducted using the Control Preference Scale. Multiple logistic regression analysis was used for testing the association of patient characteristics with preferences for participation. Patients, in general, preferred adopting a passive role. However, predictors for adopting an active participatory role were the patient's gender (odds ratio = 1.8), education (odds ratio = 2.2), living condition (odds ratio = 1.8) and occupational status (odds ratio = 2.0). A probability of 53% was estimated, which female senior citizens with at least a high school degree and who lived alone would prefer an active role in clinical decision-making. At the same time, a working cohabiting male with less than a high school degree had a probability of 8% for active participation in clinical decision making in nursing care. Patient preferences for participation differed considerably and are best elicited by assessment of the individual patient. Relevance to clinical practice. The nurses have a professional responsibility to act in such a way that patients can participate and make decisions according to their own values from an informed position. Access to knowledge of patients'basic assumptions and preferences for participation is of great value for nurses in the care process. There is a need for nurses to use structured methods and tools for eliciting individual patient preferences regarding participation in clinical decision-making.

Although abortion became legal in India in 1971, many women are unaware of the law. Behavior change communication interventions may be an effective way to promote awareness of the law and change knowledge of and perceptions about abortion, particularly in settings in which abortion is stigmatized. To evaluate the effectiveness of a behavior change communication intervention to improve women's knowledge about India's abortion law and their perceptions about abortion, a quasi-experimental study was conducted in intervention and comparison districts in Bihar and Jharkhand. Household surveys were administered at baseline in 2008 and at follow-up in 2010 to independent, randomly selected cross-sectional samples of rural married women aged 15-49. Logistic regression difference-in-differences models were used to assess program effectiveness. Analysis demonstrated program effectiveness in improving awareness and perceptions about abortion. The changes in the odds of knowing that abortion is legal and where to obtain safe abortion services were larger between baseline and follow-up in the intervention districts than the changes in odds observed in the comparison districts (odds ratios, 16.1 and 1.9, respectively). Similarly, the increase in women's perception of greater social support for abortion within their families and the increase in perceived self-efficacy with respect to family planning and abortion between baseline and follow-up was greater in the intervention districts than in the comparison districts (coefficients, 0.17 and 0.18, respectively). Behavior change communication interventions can be effective in improving knowledge of and perceptions about abortion in settings in which lack of accurate knowledge hinders women's access to safe abortion services. Multiple approaches should be used when attempting to improve knowledge and perceptions about stigmatized health issues such as abortion.

In ST-elevation myocardial infarction, time to reperfusion is crucial for the prognosis. Symptom presentation in myocardial infarction influences pre-hospital delay times but studies about differences in symptoms between patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction are sparse and inconclusive. The aim was to compare symptoms, first medical contact and pre-hospital delay times in patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction. This multicentre, observational study included 694 myocardial infarction patients from five hospitals. The patients filled in a questionnaire about their pre-hospital experiences within 24 h of hospital admittance. Chest pain was the most common symptom in ST-elevation myocardial infarction and non-ST-elevation myocardial infarction (88.7 vs 87.0%, p=0.56). Patients with cold sweat (odds ratio 3.61, 95% confidence interval 2.29-5.70), jaw pain (odds ratio 2.41, 95% confidence interval 1.04-5.58), and nausea (odds ratio 1.70, 95% confidence interval 1.01-2.87) were more likely to present with ST-elevation myocardial infarction, whereas the opposite was true for symptoms that come and go (odds ratio 0.58, 95% confidence interval 0.38-0.90) or anxiety (odds ratio 0.52, 95% confidence interval 0.29-0.92). Use of emergency medical services was higher among patients admitted with ST-elevation myocardial infarction. The pre-hospital delay time from symptom onset to first medical contact was significantly longer in non-ST-elevation myocardial infarction (2:05 h vs 1:10 h, p=0.001). Patients with ST-elevation myocardial infarction differed from those with non-ST-elevation myocardial infarction regarding symptom presentation, ambulance utilisation and pre-hospital delay times. This knowledge is important to be aware of for all healthcare personnel and the general public especially in order to recognise symptoms suggestive of ST-elevation myocardial infarction and when to decide if there is a need for an ambulance.

The Council of Europe has recommended that member states of European Union encourage their citizens to make decisions about their healthcare before they lose capacity to do so. However, it is unclear whether the public wants to make such decisions beforehand. To examine public preferences for self-involvement in end-of-life care decision-making and identify associated factors. A population-based survey with 9344 adults in England, Belgium, Germany, Italy, the Netherlands, Portugal and Spain. Across countries, 74% preferred self-involvement when capable; 44% preferred self-involvement when incapable through, for example, a living will. Four factors were associated with a preference for self-involvement across capacity and incapacity scenarios, respectively: higher educational attainment ((odds ratio = 1.93-2.77), (odds ratio = 1.33-1.80)); female gender ((odds ratio = 1.27, 95% confidence interval = 1.14-1.41), (odds ratio = 1.30, 95% confidence interval = 1.20-1.42)); younger-middle age ((30-59 years: odds ratio = 1.24-1.40), (50-59 years: odds ratio = 1.23, 95% confidence interval = 1.04-1.46)) and valuing quality over quantity of life or valuing both equally ((odds ratio = 1.49-1.58), (odds ratio = 1.35-1.53)). Those with increased financial hardship (odds ratio = 0.64-0.83) and a preference to die in hospital (not a palliative care unit) (odds ratio = 0.73, 95% confidence interval = 0.60-0.88), a nursing home or residential care (odds ratio = 0.73, 95% confidence interval = 0.54-0.99) were less likely to prefer self-involvement when capable. For the incapacity scenario, single people were more likely to prefer self-involvement (odds ratio = 1.34, 95% confidence interval = 1.18-1.53). Self-involvement in decision-making is important to the European public. However, a large proportion of the public prefer to not make decisions about their care in advance of incapacity. Financial hardship, educational attainment, age, and preferences regarding quality and quantity of life require further examination; these factors should be considered in relation to policy.

Objectives. We examined the association of Internet-related communication inequalities on human papillomavirus (HPV) vaccine awareness and infection knowledge. Methods. We drew data from National Cancer Institute’s 2007 Health Information National Trends Survey (n = 7674). We estimated multivariable logistic regression models to assess Internet use and Internet health information seeking on HPV vaccine awareness and infection knowledge. Results. Non–Internet users, compared with general Internet users, had significantly lower odds of being aware of the HPV vaccine (odds ratio [OR] = 0.42; 95% confidence interval [CI] = 0.34, 0.51) and knowing that HPV causes cervical cancer (OR = 0.70; 95% CI = 0.52, 0.95). Among general health information seekers, non–Internet seekers compared with Internet information seekers exhibit significantly lower odds of HPV vaccine awareness (OR = 0.59; 95% CI = 0.46, 0.75), and of knowing about the link between HPV infection and cervical cancer (OR = 0.79; 95% CI = 0.63, 0.99) and the sexual transmission of HPV (OR = 0.71; 95% CI = 0.57, 0.89). Among cancer information seekers, there were no differences in outcomes between Internet seekers and non–Internet seekers. Conclusions. Use of a communication channel, such as the Internet, whose use is already socially and racially patterned, may widen observed disparities in vaccine completion rates. PMID:22970692

To describe the level of knowledge regarding risk factors and warning signs for stroke and heart attack among White and African American adults in Michigan and to quantify racial disparities. Knowledge of stroke and heart attack risk factors and warning signs was assessed by using data from the 2004 Michigan Behavioral Risk Factor Survey. Prevalence estimates of knowledge were generated, and statistical differences in knowledge between Whites and African Americans were assessed. Adequate knowledge was defined as knowing 3 correct warning signs or risk factors. Logistic regression models were used to quantify the racial disparity in knowledge while controlling for potential confounding. Whites had substantially higher levels of adequate knowledge of risk factors (stroke: 31.6% vs 13.8%; heart attack: 52.6% vs 24.3%) and warning signs (stroke: 30.0% vs 17.2%; heart attack: 29.3% vs 13.8%) compared with African Americans (all observed differences were significant at P < .05). The odds of adequate knowledge of risk factors (stroke: adjusted odds ratio [AOR] 2.9; heart attack: AOR 3.4) and warning signs (stroke: AOR 2.0; heart attack: AOR 2.4) were significantly higher for Whites than for African Americans. A strong racial disparity in the knowledge of stroke and heart attack risk factors and warning signs exists among Michigan adults. Communitywide public education programs in conjunction with targeted interventions for at-risk populations are necessary to produce meaningful improvements in the awareness of stroke and heart attack risk factors and warning signs among Michigan adults.

Objective In this study, we investigated whether regular use of aspirin or acetaminophen was associated with risk of cervical cancer in women treated at an American cancer hospital. Methods This case-control study included 328 patients with cervical cancer and 1,312 controls matched on age and decade enrolled. Controls were women suspected of having but not ultimately diagnosed with a neoplasm. Analgesic use was defined as regular (at least once per week for ≥6 months), frequent (≥7 tablets/week), very long term (≥11 years), or frequent, long term (≥7 tablets per week for ≥5 years). Results Compared to nonusers, frequent aspirin use was associated with decreased odds of cervical cancer (odds ratio, 0.53; 95%confidence interval, 0.29–0.97). A slightly larger association was observed with frequent, long-term use of aspirin (odds ratio, 0.46; 95% confidence interval, 0.22–0.95). Acetaminophen use was not associated with the risk of cervical cancer. Conclusions Our findings suggest that frequent and frequent, long-term use of aspirin is associated with decreased odds of cervical cancer. To our knowledge, this is the first US-based study examining these associations. Given the widespread use of nonsteroidal anti-inflammatory drugs and acetaminophen worldwide, further investigations of the possible role of analgesics in cervical cancer, using a larger sample size with better-defined dosing regimens, are warranted.

India accounts for approximately 72% of reported diphtheria cases globally, the majority of which occur in the state of Andhra Pradesh. The aim of this study is to better understand lack of knowledge on diphtheria vaccination and to determine factors associated with diphtheria and low knowledge and negative attitudes. We performed a 1:1 case-control study of hospitalized diphtheria cases in Hyderabad. Eligible case patients were 10 years of age or older, resided within the city of Hyderabad and were diagnosed with diphtheria per the case definition. Patients admitted to the hospital for nonrespiratory communicable diseases and residing in the same geographic region as that of cases were eligible for enrolment as controls : There were no statistical differences in disease outcome by gender, education, economic status and mean room per person sleeping in the house in case and control subjects. Not having heard of diphtheria (adjusted odds ratio: 3.56; 95% confidence intervals: 1.58-8.04] and not believing that vaccines can prevent people from getting diseases (adjusted odds ratio: 3.99; 95% confidence intervals: 1.18-13.45) remained significantly associated with diphtheria on multivariate analysis. To reduce the burden of diphtheria in India, further efforts to educate the public about diphtheria should be considered.

We have analyzed the relationship between donor mismatches at each HLA locus and development of HLA locus-specific antibodies in patients listed for repeat transplantation. HLA antibody screening was undertaken using single-antigen beads in 131 kidney transplant recipients returning to the transplant waiting list following first graft failure. The number of HLA mismatches and the calculated reaction frequency of antibody reactivity against 10,000 consecutive deceased organ donors were determined for each HLA locus. Two-thirds of patients awaiting repeat transplantation were sensitized (calculated reaction frequency over 15%) and half were highly sensitized (calculated reaction frequency of 85% and greater). Antibody levels peaked after re-listing for repeat transplantation, were independent of graft nephrectomy and were associated with length of time on the waiting list (odds ratio 8.4) and with maintenance on dual immunosuppression (odds ratio 0.2). Sensitization was independently associated with increasing number of donor HLA mismatches (odds ratio 1.4). All mismatched HLA loci contributed to the development of HLA locus-specific antibodies (HLA-A: odds ratio 3.2, HLA-B: odds ratio 3.4, HLA-C: odds ratio 2.5, HLA-DRB1: odds ratio 3.5, HLA-DRB3/4/5: odds ratio 3.9, and HLA-DQ: odds ratio 3.0 (all significant)). Thus, the risk of allosensitization following failure of a first renal transplant increases incrementally with the number of mismatches at all HLA loci assessed. Maintenance of re-listed patients on dual immunosuppression was associated with a reduced risk of sensitization.

Ischemic optic neuropathy is the most common form of perioperative visual loss, with highest incidence in cardiac and spinal fusion surgery. To date, potential risk factors have been identified in cardiac surgery by only small, single-institution studies. To determine the preoperative risk factors for ischemic optic neuropathy, the authors used the National Inpatient Sample, a database of inpatient discharges for nonfederal hospitals in the United States. Adults aged 18 yr or older admitted for coronary artery bypass grafting, heart valve repair or replacement surgery, or left ventricular assist device insertion in National Inpatient Sample from 1998 to 2013 were included. Risk of ischemic optic neuropathy was evaluated by multivariable logistic regression. A total of 5,559,395 discharges met inclusion criteria with 794 (0.014%) cases of ischemic optic neuropathy. The average yearly incidence was 1.43 of 10,000 cardiac procedures, with no change during the study period (P = 0.57). Conditions increasing risk were carotid artery stenosis (odds ratio, 2.70), stroke (odds ratio, 3.43), diabetic retinopathy (odds ratio, 3.83), hypertensive retinopathy (odds ratio, 30.09), macular degeneration (odds ratio, 4.50), glaucoma (odds ratio, 2.68), and cataract (odds ratio, 5.62). Female sex (odds ratio, 0.59) and uncomplicated diabetes mellitus type 2 (odds ratio, 0.51) decreased risk. The incidence of ischemic optic neuropathy in cardiac surgery did not change during the study period. Development of ischemic optic neuropathy after cardiac surgery is associated with carotid artery stenosis, stroke, and degenerative eye conditions.

ICU clinicians are primarily involved in organ donation after brain death of ICU patients. Their perceptions of organ donation may affect outcomes. Our objective was to describe ICU clinician's perceptions and experience of organ donation. Cross-sectional study among physicians and nurses (90 ICUs in France). We used factorial correspondence analysis to describe categories of clinicians regarding their perceptions and experience of organ donation. Factors associated with a positive (motivating) or negative (stressful) experiences were studied using multivariate logistic regression. Physicians and nurses. Three thousand three hundred twenty-five clinicians working in 77 ICUs returned questionnaires. Professionals who experienced organ donation as motivating were younger (odds ratio, 0.41; 95% CI, 0.32-0.53; p < 0.001), more often potential organ donors (odds ratio, 1.92; 95% CI, 1.56-2.35; p < 0.001), less likely to describe inconsistency (odds ratio, 0.43; 95% CI, 0.23-0.8) or complexity (odds ratio, 0.55; 95% CI, 0.45-0.67) of their feelings versus their professional activity, less likely to report that organ donation was not a priority in their ICU (odds ratio, 0.68; 95% CI, 0.55-0.84), and more likely to have participated in meetings of transplant coordinators with relatives (odds ratio, 1.71; 95% CI, 1.37-2.14; p < 0.001). Professionals who felt organ donation was stressful were older (odds ratio, 1.84; 95% CI, 1.34-2.54; p < 0.001), less often physicians (odds ratio, 0.58; 95% CI, 0.44-0.77; p < 0.001), more likely to describe shift from curative care to organ donation as emotionally complex (odds ratio, 1.83; 95% CI, 1.52-2.21; p < 0.001), care of relatives of brain-dead patients as complex (odds ratio, 1.59; 95% CI, 1.32-1.93; p < 0.001), and inconsistency and complexity of personal feelings about organ donation versus professional activity (odds ratio, 3.25; 95% CI, 1.92-5.53; p < 0.001), and more likely to have little experience with caring for potential organ donors (odds ratio, 1.49; 95% CI, 1.09-2.04). Significant differences exist among ICU clinician's perceptions of organ donation. Whether these differences affect family experience and consent rates deserves investigation.

The male marriage squeeze in China may increase the prevalence of male same-sex sexual behaviors among unmarried male migrants who lack stable female sexual partners. The same-sex sexual behaviors among unmarried male migrants appear to be at high risk of transmission of human immunodeficiency virus (HIV) and sexually transmitted infections (STIs), mainly because of a lack of knowledge of these diseases. Using data from the "Survey on Reproductive Health and Family Life of Migrant Male Bachelors in Urban Areas" conducted in Xi'an City, Shaanxi Province, in December 2009 and January 2010, this study compares same-sex sexual behaviors of unmarried with that of married male migrants (including married but separated men who are migrating without their spouse or partner and cohabitating men who are migrating with their spouse or partner). It is reported that the prevalence of same-sex sexual behaviors among unmarried males reaches 11%, more than twice the 5.1% reported by married but separated men and thrice the 3.8% reported by cohabitating men. It also appears that the same-sex sexual behaviors is significantly associated with men's attitudes toward same-sex sexual behaviors (odds ratio = 1.59, p < .001), toward life-long bachelorhood (odds ratio = 1.35, p < .01), and with marital status (odds ratio = 0.37, p < .01). The frequency of condom use appears to be higher among unmarried men than among men who are married, whether or not they migrated with their wives, and is significantly associated with scores on knowledge about HIV/AIDS (estimated coefficient = .12, p < .001) and STIs (estimated coefficient = .22, p < .01). It is also associated with the likelihood of same-sex sexual behaviors (estimated coefficients = .83, p < .01) and marital status (estimated coefficients for married but separated = -.50, p < .05; estimated coefficients for cohabitating = -.77, p < .001).

To describe the methods preferred for contraception, evaluate preferences and adherence to modern contraceptive methods, and determine the factors associated with contraceptive choices among tertiary students in South East Nigeria. A questionnaire-based cross-sectional study of sexual habits, knowledge of contraceptive methods, and patterns of contraceptive choices among a pooled sample of unmarried students from the three largest tertiary educational institutions in Enugu city, Nigeria was done. Statistical analysis involved descriptive and inferential statistics at the 95% level of confidence. A total of 313 unmarried students were studied (194 males; 119 females). Their mean age was 22.5±5.1 years. Over 98% of males and 85% of females made their contraceptive choices based on information from peers. Preferences for contraceptive methods among female students were 49.2% for traditional methods of contraception, 28% for modern methods, 10% for nonpharmacological agents, and 8% for off-label drugs. Adherence to modern contraceptives among female students was 35%. Among male students, the preference for the male condom was 45.2% and the adherence to condom use was 21.7%. Multivariate analysis showed that receiving information from health personnel/media/workshops (odds ratio 9.54, 95% confidence interval 3.5-26.3), health science-related course of study (odds ratio 3.5, 95% confidence interval 1.3-9.6), and previous sexual exposure prior to university admission (odds ratio 3.48, 95% confidence interval 1.5-8.0) all increased the likelihood of adherence to modern contraceptive methods. An overwhelming reliance on peers for contraceptive information in the context of poor knowledge of modern methods of contraception among young people could have contributed to the low preferences and adherence to modern contraceptive methods among students in tertiary educational institutions. Programs to reduce risky sexual behavior among these students may need to focus on increasing the content and adequacy of contraceptive information held by people through regular health worker-led, on-campus workshops.

Methicillin-resistant Staphylococcus aureus (MRSA) infections and Clostridium difficile infections (CDI) are major health care-associated infections (HAIs). Little is known about patients' knowledge of these HAIs. Therefore, we surveyed patients to determine awareness, knowledge, and perceptions of MRSA infections and CDI. An interviewer-administered questionnaire. A tertiary care academic medical center. Adult patients who met at least one of the following criteria: at risk of CDI or MRSA infection, current CDI or colonization or current MRSA infection or colonization, or history of CDI or MRSA infection. Two unique surveys were developed and administered to 100 patients in 2011. Overall, 76% of patients surveyed were aware of MRSA, whereas 44% were aware of C difficile. The strongest predictor of patients' awareness of these infections was having a history of HAI. Patients with a history of HAI were significantly more likely to have heard of both MRSA (odds ratio, 13.29; 95% confidence interval, 2.84-62.14; P = .001) and C difficile (odds ratio, 9.78; 95% confidence interval, 2.66-35.95; P = .001), than those patients without a history of HAI. There was also a significant positive association between having a history of HAI and greater knowledge of the risk factors, health consequences, and prevention techniques relative to CDI and MRSA infections. There are additional opportunities to engage patients about the risks and consequences of MRSA and CDIs, particularly those without a history of HAI.

In Nepal, following the liberalization of the abortion law, expansion and scaling up of services proceeded in parallel with efforts to create awareness of the legalization status of abortion and provide women with information about where services are available. This article assesses the effectiveness of these programmatic interventions in the early years of the country's abortion program. Data from a 2006 national survey are analyzed with 2 outcome measures-awareness of the legal status of abortion and knowledge of places to obtain abortion services among women ages 15 to 44 years. The variations in the outcomes are analyzed by ecological-development subregion, residence, education, household wealth quintile, age, and number of living children. Bivariate and multivariate logistic regression techniques are used. Overall 32.3% (95% confidence interval = 31.4% to 33.2%) of the respondents were aware of the legal status of abortion and 56.5% (95% confidence interval = 55.5% to 57.4%) knew of a place where they could obtain an abortion. Both outcome measures showed considerable variations by the covariates. Women with secondary or higher level of education had the highest odds ratio of being aware of the law and having knowledge of a source for abortion services. Ecological-development subregions showed the second highest levels of odds ratios. Significant disparities among the population subgroups existed in the diffusion of awareness of the legal status of abortion and having knowledge of a place for abortion services in Nepal. The results point to which population subgroups to focus on and also serve as a baseline for assessing future progress in the diffusion process. © 2012 APJPH.

To investigate the predictive value of both patients' motivation and effort in their management of Type 2 diabetes and their life circumstances for the development of foot ulcers and amputations. This study was based on the Diabetes Care in General Practice study and Danish population and health registers. The associations between patient motivation, effort and life circumstances and foot ulcer prevalence 6 years after diabetes diagnosis and the incidence of amputation in the following 13 years were analysed using odds ratios from logistic regression and hazard ratios from Cox regression models, respectively. Foot ulcer prevalence 6 years after diabetes diagnosis was 2.93% (95% CI 1.86-4.00) among 956 patients. General practitioners' indication of 'poor' vs 'very good' patient motivation for diabetes management was associated with higher foot ulcer prevalence (odds ratio 6.11, 95% CI 1.22-30.61). The same trend was seen for 'poor' vs 'good' influence of the patient's own effort in diabetes treatment (odds ratio 7.06, 95% CI 2.65-18.84). Of 1058 patients examined at 6-year follow-up, 45 experienced amputation during the following 13 years. 'Poor' vs 'good' influence of the patients' own effort was associated with amputation (hazard ratio 7.12, 95% CI 3.40-14.92). When general practitioners assessed the influence of patients' life circumstances as 'poor' vs 'good', the amputation incidence increased (hazard ratio 2.97, 95% CI 1.22-7.24). 'Poor' vs 'very good' patient motivation was also associated with a higher amputation incidence (hazard ratio 7.57, 95% CI 2.43-23.57), although not in fully adjusted models. General practitioners' existing knowledge of patients' life circumstances, motivation and effort in diabetes management should be included in treatment strategies to prevent foot complications. © 2014 The Authors.

Few studies discuss causes and outcomes of peritonitis in low-income settings. This study describes epidemiology of patients with peritonitis at a Rwandan referral hospital. Identification of risk factors associated with mortality and unplanned reoperation could improve management of peritonitis. Data were collected on demographics, clinical presentation, operative findings, and outcomes for all patients with peritonitis. Multivariate regression analysis identified factors associated with in-hospital mortality and unplanned reoperation. A total of 280 patients presented with peritonitis over a 6-month period. Causes of peritonitis were complications of intestinal obstruction (39%) and appendicitis (17%). Thirty-six (13%) patients required unplanned reoperation, and in-hospital mortality was 17%. Factors associated with increased odds of in-hospital mortality were unplanned reoperation (adjusted odds ratio 34.12), vasopressor use (adjusted odds ratio 24.91), abnormal white blood cell count (adjusted odds ratio 12.6), intensive care unit admission (adjusted odds ratio 9.06), and American Society of Anesthesiologist score ≥3 (adjusted odds ratio 7.80). Factors associated with increased odds of unplanned reoperation included typhoid perforation (adjusted odds ratio 5.92) and hypoxia on admission (adjusted odds ratio 3.82). Peritonitis in Rwanda presents with high morbidity and mortality. Minimizing delays in care is important, as many patients with intestinal obstruction present with features of peritonitis. A better understanding of patient care and management prior to arrival at the referral hospital is needed to identify areas for improvement at the health center and district hospital.

The success of corneal grafting in visual rehabilitation of the corneal blind in India depends on survival of the grafts. Understanding the causes of graft failure may help reduce the risk of failure. We studied these causes in a series of 638 graft failures at our institution. Multivariate logistic regression analysis was used to evaluate the association of particular causes of graft failure with indications for grafting, socioeconomic status, age, sex, host corneal vascularization, donor corneal quality, and experience of surgeon. The major causes of graft failure were allograft rejection (29.2%), increased intraocular pressure (16.9%), infection excluding endophthalmitis (15.4%), and surface problems (12.7%). The odds of infection causing graft failure were significantly higher in patients of lower socioeconomic status (odds ratio 2.45, 95% CI 1.45-4.15). Surface problems as a cause of graft failure was significantly associated with grafts done for corneal scarring or for regrafts (odds ratio 3.36, 95% CI 1.80-6.30). Increased intraocular pressure as a cause of graft failure had significant association with grafts done for aphakic or pseudophakic bullous keratopathy, congenital conditions or glaucoma, or regrafts (odds ratio 2.19, 95% CI 1.25-3.84). Corneal dystrophy was the indication for grafting in 12 of the 13 cases of graft failure due to recurrence of host disease. Surface problems, increased intraocular pressure, and infection are modifiable risk factors that are more likely to cause graft failure in certain categories of patients in India. Knowledge about these associations can be helpful in looking for and aggressively treating these modifiable risk factors in the at-risk categories of corneal graft patients. This can possibly reduce the chance of graft failure.

Low levels of food security are associated with dyslipidemia and chronic disease in adults, particularly in women. There is a gap in knowledge about the relationship between food security among youth and dyslipidemia and chronic disease. We investigated the relationship between food security status and dyslipidemia among low-income adolescents. We analyzed data from adolescents aged 12 to 18 years (N = 1,072) from households with incomes at or below 200% of the federal poverty level from the National Health and Nutrition Examination Survey (NHANES) 2003-2010. We used logistic regression to examine the relationship between household food security status and the odds of having abnormalities with fasting total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), serum triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C), TG/HDL-C ratio, and apolipoprotein B (Apo B). Models included age, sex, race/ethnicity, smoking status, partnered status in the household, and maternal education, with additional adjustment for adiposity. Household food security status was not associated with elevated TC or LDL-C. Adolescents with marginal food security were more likely than food-secure peers to have elevated TGs (odds ratio [OR] = 1.86; 95% confidence interval [CI], 1.14-3.05), TG/HDL-C ratio (OR = 1.74; 95% CI, 1.11-2.82), and Apo B (OR = 1.98; 95% CI, 1.17-3.36). Female adolescents with marginal food security had greater odds than male adolescents of having low HDL-C (OR = 2.69; 95% CI, 1.14-6.37). No elevated odds of dyslipidemia were found for adolescents with low or very low food security. Adjustment for adiposity did not attenuate estimates. In this nationally representative sample, low-income adolescents living in households with marginal food security had increased odds of having a pattern consistent with atherogenic dyslipidemia, which represents a cardiometabolic burden above their risk from adiposity alone.

Sudden cardiac death is the leading cause of death in athletes. Evidence on current sudden cardiac death prevention through preparticipation history, physicals, and noninvasive cardiovascular diagnostics has demonstrated a low sensitivity for detection of athletes at high risk of sudden cardiac death. Data are lacking on automated external defibrillator programs specifically initiated to respond to rare dysrhythmia in younger, relatively low-risk populations. Surveys were mailed to the head athletic trainers of all National Collegiate Athletic Association Division I athletics programs listed in the National Athletic Trainers' Association directory. In all, 303 surveys were mailed; 186 departments (61%) responded. Seventy-two percent (133) of responding National Collegiate Athletic Association Division I athletics programs have access to automated external defibrillator units; 54% (101) own their units. Proven medical benefit (55%), concern for liability (51%), and affordability (29%) ranked highest in frequency of reasons for automated external defibrillator purchase. Unit cost (odds ratio = 1.01; 95% confidence interval, 1.01-1.0), donated units (odds ratio = 1.92; confidence interval, 3.66-1.01), institution size (odds ratio =.0001; confidence interval, 1.3 E-4 to 2.2E-05), and proven medical benefit of automated external defibrillators (odds ratio = 24; confidence interval, 72-8.1) were the most significant predictors of departmental defibrillator ownership. Emergency medical service response time and sudden cardiac death event history were not significantly predictive of departmental defibrillator ownership. The majority of automated external defibrillator interventions occurred on nonathletes. Many athletics medicine programs are obtaining automated external defibrillators without apparent criteria for determination of need. Usage and maintenance policies vary widely among departments with unit ownership or access. Programs need to approach the issue of unit acquisition and implementation with knowledge of the surrounding emergency medical service system, geography of their individual sports medicine facilities, numbers and relative risk of their athletes, and budgetary constraints.

The authors examined the prospective relationship between physical activity and incident depression and explored potential moderators. Prospective cohort studies evaluating incident depression were searched from database inception through Oct. 18, 2017, on PubMed, PsycINFO, Embase, and SPORTDiscus. Demographic and clinical data, data on physical activity and depression assessments, and odds ratios, relative risks, and hazard ratios with 95% confidence intervals were extracted. Random-effects meta-analyses were conducted, and the potential sources of heterogeneity were explored. Methodological quality was assessed using the Newcastle-Ottawa Scale. A total of 49 unique prospective studies (N=266,939; median proportion of males across studies, 47%) were followed up for 1,837,794 person-years. Compared with people with low levels of physical activity, those with high levels had lower odds of developing depression (adjusted odds ratio=0.83, 95% CI=0.79, 0.88; I 2 =0.00). Furthermore, physical activity had a protective effect against the emergence of depression in youths (adjusted odds ratio=0.90, 95% CI=0.83, 0.98), in adults (adjusted odds ratio=0.78, 95% CI=0.70, 0.87), and in elderly persons (adjusted odds ratio=0.79, 95% CI=0.72, 0.86). Protective effects against depression were found across geographical regions, with adjusted odds ratios ranging from 0.65 to 0.84 in Asia, Europe, North America, and Oceania, and against increased incidence of positive screen for depressive symptoms (adjusted odds ratio=0.84, 95% CI=0.79, 0.89) or major depression diagnosis (adjusted odds ratio=0.86, 95% CI=0.75, 0.98). No moderators were identified. Results were consistent for unadjusted odds ratios and for adjusted and unadjusted relative risks/hazard ratios. Overall study quality was moderate to high (Newcastle-Ottawa Scale score, 6.3). Although significant publication bias was found, adjusting for this did not change the magnitude of the associations. Available evidence supports the notion that physical activity can confer protection against the emergence of depression regardless of age and geographical region.

In recent years, numerous US medical schools and academic medical centers have enacted policies preventing pharmaceutical sales representatives from interacting directly with students. Little is known about how pharmaceutical sales representatives affect trainees' knowledge about pharmaceutical prescribing. To determine whether there is an association between medical trainees' interactions with pharmaceutical promotion and their preferences in medication use. We surveyed a nationally representative sample of first- and fourth-year medical students and third-year residents by randomly selecting at least 14 trainees at each level per school. All trainees were asked how often they used different educational resources to learn about prescription drugs. Among fourth-year students and residents, we posed a series of multiple choice knowledge questions asking about the appropriate initial therapy for clinical scenarios involving patients with diabetes, hyperlipidemia, hypertension, and difficulty sleeping. Evidence-based answers followed widely used clinical guidelines, while marketed-drug answers favored brand-name drugs over generic alternatives. We used survey answers to build an industry relations index assessing each trainee's level of acceptance of pharmaceutical promotion; we used proportional odds logistic regression models to estimate the association between the index and responses to the knowledge questions. The 1601 student (49.0% response rate) and 735 resident (42.9% response rate) respondents reported common use of unfiltered sources of drug information such as Google (74.2%-88.9%) and Wikipedia (45.2%-84.5%). We found that 48% to 90% of fourth-year students and residents accurately identified evidence-based prescribing choices. A 10-point higher industry relations index was associated with 15% lower odds of selecting an evidence-based prescribing choice (odds ratio [OR], 0.85; 95% CI, 0.79-0.92) (P < .001). There was also a significant association between the industry relations index and greater odds of choosing to prescribe brand-name drugs (OR, 1.08; 95% CI, 1.00-1.16) (P = .04). Among physician trainees, our survey showed an association between positive attitudes toward industry-physician interactions and less knowledge about evidence-based prescribing and greater inclination to recommend brand-name drugs. Policies intended to insulate trainees from pharmaceutical marketing may promote better educational outcomes.

AKI is a serious complication after cardiac surgery. Although high urinary concentrations of the tubular protein uromodulin, a marker of tubular health, are associated with less AKI in animal models, its relationship in humans is unknown. A post hoc analysis of a prospective cohort study of 218 adults undergoing on-pump cardiac surgery between 2004 and 2011 was conducted. Multivariable logistic and linear regression analyses were used to evaluate the associations of preoperative urinary uromodulin-to-creatinine ratio with postoperative AKI (defined as a rise in serum creatinine of >0.3 mg/dl or >1.5 times baseline); severe AKI (doubling of creatinine or need for dialysis) and peak postoperative serum creatinine over the first 72 hours. Mean age was 68 years, 27% were women, 95% were white, and the median uromodulin-to-creatinine ratio was 10.0 μg/g. AKI developed in 64 (29%) patients. Lower urinary uromodulin-to-creatinine ratio was associated with higher odds for AKI (odds ratio, 1.49 per 1-SD lower uromodulin; 95% confidence interval, 1.04 to 2.13), which was marginally attenuated after multivariable adjustment (odds ratio, 1.43; 95% confidence interval, 0.99 to 2.07). The lowest uromodulin-to-creatinine ratio quartile was also associated with higher odds for AKI relative to the highest quartile (odds ratio, 2.94; 95% confidence interval, 1.19 to 7.26), which was slightly attenuated after multivariable adjustment (odds ratio, 2.43; 95% confidence interval, 0.91 to 6.48). A uromodulin-to-creatinine ratio below the median was associated with higher adjusted odds for severe AKI, although this did not reach statistical significance (odds ratio, 4.03; 95% confidence interval, 0.87 to 18.70). Each 1-SD lower uromodulin-to-creatinine ratio was associated with a higher adjusted mean peak serum creatinine (0.07 mg/dl per SD; 95% confidence interval, 0.02 to 0.13). Lower uromodulin-to-creatinine ratio is associated with higher odds of AKI and higher peak serum creatinine after cardiac surgery. Additional studies are needed to confirm these preliminary results.

An increased risk of preterm birth in women with joint hypermobility syndrome or Ehlers-Danlos syndrome is suspected. In this nationwide cohort study from 1997 through 2011, women with either joint hypermobility syndrome or Ehlers-Danlos syndrome or both disorders were identified through the Swedish Patient Register, and linked to the Medical Birth Register. Thereby, 314 singleton births to women with joint hypermobility syndrome/Ehlers-Danlos syndrome before delivery were identified. These births were compared with 1 247 864 singleton births to women without a diagnosis of joint hypermobility syndrome/Ehlers-Danlos syndrome. We used logistic regression, adjusted for maternal age, smoking, parity, and year of birth, to calculate adjusted odds ratios for adverse pregnancy outcomes. Maternal joint hypermobility syndrome/Ehlers-Danlos syndrome was not associated with any of our outcomes: preterm birth (adjusted odds ratio = 0.6, 95% confidence interval 0.3-1.2), preterm premature rupture of membranes (adjusted odds ratio = 0.8; 95% confidence interval 0.3-2.2), cesarean section (adjusted odds ratio = 0.9, 95% confidence interval 0.7-1.2), stillbirth (adjusted odds ratio = 1.1, 95% confidence interval 0.2-7.9), low Apgar score (adjusted odds ratio = 1.6, 95% confidence interval 0.7-3.6), small for gestational age (adjusted odds ratio = 0.9, 95% confidence interval 0.4-1.8) or large for gestational age (adjusted odds ratio = 1.2, 95% confidence interval 0.6-2.1). Examining only women with Ehlers-Danlos syndrome (n = 62), we found a higher risk of induction of labor (adjusted odds ratio = 2.6; 95% confidence interval 1.4-4.6) and amniotomy (adjusted odds ratio = 3.8; 95% confidence interval 2.0-7.1). No excess risks for adverse pregnancy outcome were seen in joint hypermobility syndrome. Women with joint hypermobility syndrome/Ehlers-Danlos syndrome do not seem to be at increased risk of adverse pregnancy outcome. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

Selection of a cardiac surgery provider in the managed care era.

Many health planners promote the use of competition to contain cost and improve quality of care. Using a standard econometric model, we examined the evidence for "value-based" cardiac surgery provider selection in eastern Massachusetts, where there is significant competition and managed care penetration. McFadden's conditional logit model was used to study cardiac surgery provider selection among 6952 patients and eight metropolitan Boston hospitals in 1997. Hospital predictor variables included beds, cardiac surgery case volume, objective clinical and financial performance, reputation (percent out-of-state referrals, cardiac residency program), distance from patient's home to hospital, and historical referral patterns. Subgroup analyses were performed for each major payer category. Distance from patient's home to hospital (odds ratio 0.90; P =.000) and the historical referral pattern from each patient's hometown (z = 45.305; P =.000) were important predictors in all models. A cardiac surgery residency enhanced the probability of selection (odds ratio 5.25; P =.000), as did percent out-of-state referrals (odds ratio 1.10; P =.001). Higher mortality rates were associated with decreased probability of selection (odds ratio 0.51; P =.027), but higher length of stay was paradoxically associated with greater probability (odds ratio 1.72; P =.000). Total hospital costs were irrelevant (odds ratio 1.00; P =.179). When analyzed by payer subgroup, Medicare patients appeared to select hospitals with both low mortality (odds ratio 0.43; P =.176) and short length of stay (odds ratio 0.76; P =.213), although the results did not achieve statistical significance. The commercial managed care subgroup exhibited the least "value-based" behavior. The odds ratio for length of stay was the highest of any group (odds ratio = 2.589; P =.000) and there was a subset of hospitals for which higher mortality was actually associated with greater likelihood of selection. The observable determinants of cardiac surgery provider selection are related to hospital reputation, historical referral patterns, and patient proximity, not objective clinical or cost performance. The paradoxic behavior of commercial managed care probably results from unobserved choice factors that are not primarily based on objective provider performance.

Totally implantable venous access devices (ports) are widely used, especially for cancer chemotherapy. Although their use has been associated with upper extremity deep venous thrombosis, the risk factors of upper extremity deep venous thrombosis in patients with a port are not studied adequately. The Healthcare Cost and Utilization Project's Florida State Ambulatory Surgery and Services Database was queried between 2007 and 2011 for patients who underwent outpatient port insertion, identified by Current Procedural Terminology code. Patients were followed in the State Ambulatory Surgery and Services Database, State Inpatient Database, and State Emergency Department Database for upper extremity deep venous thrombosis occurrence. The cohort was divided into a test cohort and a validation cohort based on the year of port placement. A multivariable logistic regression model was developed to identify risk factors for upper extremity deep venous thrombosis in patients with a port. The model then was tested on the validation cohort. Of the 51,049 patients in the derivation cohort, 926 (1.81%) developed an upper extremity deep venous thrombosis. On multivariate analysis, independently significant predictors of upper extremity deep venous thrombosis included age <65 years (odds ratio = 1.22), Elixhauser score of 1 to 2 compared with zero (odds ratio = 1.17), end-stage renal disease (versus no kidney disease; odds ratio = 2.63), history of any deep venous thrombosis (odds ratio = 1.77), all-cause 30-day revisit (odds ratio = 2.36), African American race (versus white; odds ratio = 1.86), and other nonwhite races (odds ratio = 1.35). Additionally, compared with genitourinary malignancies, patients with gastrointestinal (odds ratio = 1.55), metastatic (odds ratio = 1.76), and lung cancers (odds ratio = 1.68) had greater risks of developing an upper extremity deep venous thrombosis. This study identified major risk factors of upper extremity deep venous thrombosis. Further studies are needed to evaluate the appropriateness of thromboprophylaxis in patients at greater risk of upper extremity deep venous thrombosis. Copyright © 2017 Elsevier Inc.

Drug use and partner violence affect older women, yet few studies highlight age-specific HIV risks and prevention strategies. This study compares sexual risk behaviors, condom use attitudes, and HIV knowledge between midlife/older women (ages 45+) and younger women (ages 18-44) reporting methamphetamine use and partner violence in San Diego, California. Our mixed methods study used themes from a qualitative substudy (n = 18) to inform logistic regression analysis of baseline data from an HIV behavioral intervention trial (n = 154). Age-related qualitative themes included physiologic determinants, HIV knowledge, and "dodging the bullet," referring to a lifetime of uncertainty surrounding HIV serostatus after engaging in unsafe drug and sex practices. Midlife/older age was associated with never being married (24.2% vs. 51.2; p = .03), having less than a high school education/GED (12.1% vs. 34.7%; p = .04), lower condom use self-efficacy (2.87 vs. 3.19; p = .03), lower positive outcome expectancies (1.9 vs. 2.1; p = .04), and lower HIV knowledge (85.3% vs. 89.7%; p = .04); however, sexual risk behaviors were not associated with age group. In the multivariate analysis, midlife/older age remained independently associated with lower condom use self-efficacy (adjusted odds ratio, 0.49; 95% CI, 0.27-0.87) and lower HIV knowledge (adjusted odds ratio, 0.96; 95% CI, 0.93-0.99). Midlife/older methamphetamine-using women with experiences of partner violence present similar sexual risk profiles, but possess different HIV-related knowledge and attitudes toward prevention methods compared with their younger counterparts. Clinicians and public health practitioners can have a positive impact on this overlooked population by assessing HIV risks during routine screenings, encouraging HIV testing, and providing age-appropriate HIV prevention education.

To assess the impact of the education program of the Eye Care Quality and Accessibility Improvement in the Community (EQUALITY) telemedicine program on at-risk patients' knowledge about glaucoma and attitudes about eye care as well as to assess patient satisfaction with EQUALITY. New or existing patients presenting for a comprehensive eye exam (CEE) at one of two retail-based primary eye clinics were enrolled based on ≥1 of the following at-risk criteria for glaucoma: African Americans ≥40 years of age, Whites ≥50 years of age, diabetes, family history of glaucoma, and/or preexisting diagnosis of glaucoma. A total of 651 patients were enrolled. A questionnaire was administered prior to the patients' CEE and prior to the patients receiving any of the evidence-based eye health education program; a follow-up questionnaire was administered 2-4 weeks later by phone. Baseline and follow-up patient responses regarding knowledge about glaucoma and attitudes about eye care were compared using McNemar's test. Logistic regression models were used to assess the association of patient-level characteristics with improvement in knowledge and attitudes. Overall patient satisfaction was summarized. At follow-up, all patient responses in the knowledge and attitude domains significantly improved from baseline (P≤0.01 for all questions). Those who were unemployed (odds ratio =0.63, 95% confidence interval =0.42-0.95, P=0.026) or had lower education (odds ratio =0.55, 95% confidence interval =0.29-1.02, P=0.058) were less likely to improve their knowledge after adjusting for age, sex, race, and prior glaucoma diagnosis. This association was attenuated after further adjustment for other patient-level characteristics. Ninety-eight percent (n=501) of patients reported being likely to have a CEE within the next 2 years, whereas 63% (n=326) had a CEE in the previous 2 years. Patient satisfaction with EQUALITY was high (99%). Improved knowledge about glaucoma and a high intent to pursue eye care may lead to improved detection of early disease, thus lowering the risk of blindness.

Self-management support for chronic obstructive pulmonary disease (COPD) patients is recommended by UK national guidelines, but extent of implementation is unknown. We aimed to describe self-management behaviour and support among COPD patients and explore behaviour associated with having a self-management plan. We undertook cross-sectional analysis of self-reported data from diagnosed COPD patients in the Birmingham COPD Cohort study. Questionnaire items relevant to self-management behaviour, knowledge of COPD, receipt of self-management plans and advice from healthcare professionals were examined. Multiple regression models were used to identify behaviour associated with having a self-management plan. One-thousand seventy-eight participants (676 males, 62.7%, mean age 69.8 (standard deviation 9.0) years) were included. The majority reported taking medications as instructed (940, 94.0%) and receiving annual influenza vaccinations (962, 89.2%). Only 400 (40.4%) participants had self-management plans, 538 (49.9%) reported never having received advice on diet/exercise and 110 (42.7%) current smokers had been offered practical help to stop smoking in the previous year. General knowledge about COPD was moderate (mean total Bristol COPD Knowledge Questionnaire score: 31.5 (standard deviation 10.7); max score 65), corresponding to 48.5% of questions answered correctly. Having a self-management plan was positively associated with self-reported adherence to medication (odds ratio 3.10, 95% confidence interval 1.43 to 6.72), attendance at a training course (odds ratio 2.72, 95% confidence interval 1.81 to 4.12), attendance at a support group (odds ratio 6.28, 95% confidence interval 2.96 to 13.35) and better disease knowledge (mean difference 4.87, 95% confidence interval 3.16 to 6.58). Primary care healthcare professionals should ensure more widespread implementation of individualised self-management plans for all patients and improve the lifestyle advice provided. CALL FOR WIDER IMPLEMENTATION OF SELF-MANAGEMENT PLANS: Health professionals should ensure all patients with chronic lung disease receive individualized self-management plans and lifestyle advice. UK national guidelines state that patients with chronic obstructive pulmonary disease (COPD) should receive personalized self-management plans and comprehensive support to help them manage their disease. Ainee Khan and colleagues at the University of Birmingham analyzed patient questionnaire data gathered during the Birmingham COPD Cohort study to explore self-management behavior, receipt of self-management plans and advice, and patient knowledge of COPD. Of 1,078 participants, only 400 had self-management plans, and less than half reported receiving lifestyle advice or support. Those with plans were more likely to adhere to medication, had greater knowledge about COPD and were more likely to attend support groups and training courses. The authors recommend carefully-planned, wider implementation of COPD self-management plans and associated support.

Community pharmacists' knowledge of Alzheimer disease care in high- and low-income Chicago.

PubMed

Marvanova, Marketa; Henkel, Paul Jacob

This pilot study examined community pharmacists' knowledge to provide care and services for persons with Alzheimer disease (AD) and area income-based disparities in knowledge and availability of cognitive enhancers. A cross-sectional telephone survey of pharmacies (n = 137) in high- and low-income areas in Chicago was conducted on pharmacists' degree, experience, and continuing education, as well as knowledge of AD disease and treatment expectations, adverse effects (AEs) of donepezil, and self-care recommendations for insomnia. Pharmacies were selected from highest- and lowest-income zip code areas, defined using household area median incomes from the 2008-2012 American Community Survey 5-Year Estimates. In-stock availability of select cognitive enhancers was obtained. Chi-square, Fisher exact test, and simple and multiple logistic regression analyses were performed with the use of Stata 10.1. Odds were 70% lower that pharmacists in low-income areas would say there was nothing to reverse the course of AD (odds ratio [OR] 0.30, 95% confidence interval [CI] 0.13-0.70) and 7 times greater that they would recommend a medication to reverse the course of AD (OR 7.04, 95% CI 2.19-22.62) compared with pharmacists in high-income areas. Odds were more than 50% lower that pharmacists in low-income areas would name at least 1 adverse effect for donepezil (OR 0.42, 95% CI 0.19-0.92) compared with peers in high-income areas. Pharmacies in low-income areas had lower odds of having 4 of the 5 surveyed formulations of cognitive enhancers in stock. It is concerning that 20%-30% of pharmacists recommended a medication to "reverse" the course of AD, about one-half of pharmacists could not mention a single adverse effect of donepezil, and more than one-fourth of pharmacists made an inappropriate self-care sleep aid recommendation for a person with AD who was using rivastigmine patch. Although overall results regarding pharmacists' knowledge were poor, performance was significantly poorer in low-income areas. As our AD population increases, we need to strengthen pharmacists' knowledge on and competencies important for pharmacy-related AD care. Copyright © 2017 American Pharmacists Association®.

Dong, Song; Liu, Yueling; Chen, Jieping

2014-09-01

An increasing body of evidence has shown that the amino acid changes at position 1298 might eliminate methylenetetrahydrofolate reductase (MTHFR) enzyme activity, leading to insufficient folic acid and subsequent human chromosome breakage. Epidemiological studies have linked MTHFR single-nucleotide polymorphism (SNP) rs1801131 to myeloid leukemia risk, with considerable discrepancy in their results. We therefore were prompted to clarify this issue by use of a meta-analysis. The search terms were used to cover the possible reports in the MEDLINE, Web of Knowledge, and China National Knowledge Infrastructure (CNKI) databases. Odds ratios were estimated to assess the association of SNP rs1801131 with myeloid leukemia risk. Statistical heterogeneity was detected using the Q-statistic and I (2) metric. Subgroup analysis was performed by ethnicity, histological subtype, and Hardy-Weinberg equilibrium (HWE). This meta-analysis of eight publications with a total of 1,114 cases and 3,227 controls revealed no global association. Nor did the subgroup analysis according to histological subtype and HWE show any significant associations. However, Asian individuals who harbored the CC genotype were found to have 1.66-fold higher risk of myeloid leukemia (odds ratio, 1.66; 95 % confidence interval, 1.10 to 2.49; P h = 0.342; I (2) = 0.114). Our meta-analysis has presented evidence supporting a possible association between the CC genotype of MTHFR SNP rs1801131 and myeloid leukemia in Asian populations.

Death wishes in older people are common and may progress to suicidal ideation and attempts. This study used routinely collected data from the interRAI Home Care assessment to examine the prevalence and clinical predictors of death wishes in older New Zealanders assessed for home support and long-term aged residential care. Data were collected from 35 734 people aged over 65 during 2012-2014. Chi-squared analyses were used to determine significant relationships between the presence of death wishes and demographic factors, health and functional status, and emotional and psychosocial well-being. A three-step hierarchical logistic regression model was used to determine the predictive variables of death wishes, and odds ratios were calculated. Death wishes were present in 9.5% of the sample. The following factors were significantly associated with death wishes: physical health (poor self-reported health, recurrent falls, severe fatigue and inadequate pain control), psychological factors (depression, major stressors and anxiety), social factors (loneliness and decline in social activities) and impaired cognition. Depression (odds ratio = 2.54, 95% confidence interval = 2.29-2.81), loneliness (odds ratio = 2.40, 95% confidence interval = 2.20-2.63) and poor self-reported health (odds ratio = 2.34, 95% confidence interval = 1.78-3.07) had the greatest odds ratios in the full model. Clinically significant depression alone cannot fully account for the development of death wishes in the elderly, and several factors are independently associated with death wishes. This knowledge can help clinicians caring for older persons to identify people who are most at risk of developing death wishes. Copyright © 2016 John Wiley & Sons, Ltd.

Our objective was to determine whether paternal depressive symptoms were associated with less father involvement among African American fathers not living with their children (ie, nonresident fathers). We analyzed survey data for 345 fathers enrolled in a program for nonresident African American fathers and their preteen sons. Father involvement included measures of contact, closeness, monitoring, communication, and conflict. We used bivariate analyses and multivariate logistic regression analysis to examine associations between father involvement and depressive symptoms. Thirty-six percent of fathers reported moderate depressive symptoms, and 11% reported severe depressive symptoms. In bivariate analyses, depressive symptoms were associated with less contact, less closeness, low monitoring, and increased conflict. In multivariate analyses controlling for basic demographic features, fathers with moderate depressive symptoms were more likely to have less contact (adjusted odds ratio: 1.7 [95% confidence interval: 1.1-2.8]), less closeness (adjusted odds ratio: 2.1 [95% confidence interval: 1.3-3.5]), low monitoring (adjusted odds ratio: 2.7 [95% confidence interval: 1.4-5.2]), and high conflict (adjusted odds ratio: 2.1 [95% confidence interval: 1.2-3.6]). Fathers with severe depressive symptoms also were more likely to have less contact (adjusted odds ratio: 3.1 [95% confidence interval: 1.4-7.2]), less closeness (adjusted odds ratio: 2.6 [95% confidence interval: 1.2-5.7]), low monitoring (adjusted odds ratio: 2.8 [95% confidence interval: 1.1-7.1]), and high conflict (adjusted odds ratio: 2.6 [95% confidence interval: 1.1-5.9]). Paternal depressive symptoms may be an important, but modifiable, barrier for nonresident African American fathers willing to be more involved with their children.

To determine the factors associated with asthma in children. The case-control study was conducted in the paediatrics clinic of Lyari General Hospital, Karachi, from May to October 2010. Children 1-15 years of age attending the clinic represented the cases, while the control group had children who were closely related (sibling or cousin) to the cases but did not have the symptoms of disease at the time. Data was collected through a proforma and analysed using SPSS 10. Of the total 346 subjects, 173(50%) each comprised the two groups. According to univariable analysis the risk factors were presence of at least one smoker (odds ratio: 3.6; 95% confidence interval: 2.3-5.8), resident of kacha house (odds ratio: 16.2; 95% confidence interval: 3.8-69.5),living in room without windows (odds ratio: 9.3; 95% confidence interval: 2.1-40.9) and living in houses without adequate sunlight (odds ratio: 1.6; 95% confidence interval: 1.2-2.4).Using multivariable modelling, family history of asthma (odds ratio: 5.9; 95% confidence interval: 3.1-11.6), presence of at least one smoker at home (odds ratio: 4.1; 95% confidence interval: 2.3-7.2), people living in a room without a window (odds ratio: 5.5; 95% confidence interval: 1.15-26.3) and people living in an area without adequate sunlight (odds ratio: 2.2; 95% confidence interval: 1.13-4.31) were found to be independent risk factors of asthma in children adjusting for age, gender and history of weaning. Family history of asthma, children living with at least one smoker at home, room without windows and people living in an area without sunlight were major risk factors of childhood asthma.

The maternal use of Bendectin (Debendox) in the first trimester of pregnancy was examined in a case-control (n = 1,427 and 3,001, respectively) study of malformed infants whose mothers were interviewed between 1974 and 1976. Mothers of infants with congenital malformation showed an increased likelihood (odds ratio = 1.40) of having used Bendectin, with a stronger association of Bendectin with birth defects for mothers who also smoked (odds ratio = 2.91). A significant association was observed between the occurrence of pyloric stenosis in the infant and exposure to Bendectin in utero (odds ratio = 4.33). When maternal sociodemographic factors, including smoking, and smoking alone, were controlled, the association between Bendectin and pyloric stenosis was further increased (odds ratio = 4.63 and 5.24, respectively). Except for a possible association of Bendectin with heart valve anomalies (odds ratio = 2.99), we were unable to document other significantly increased risks for congenital malformations.

Objective To explore the relationship between knowledge level and occupational risk exposure to HIV/AIDS in primary care health workers. Methodology Analytical cross-sectional study. 720 health workers from Santiago answered a survey about HIV/AIDS that included: knowledge level (appropriate, inappropriate), occupational risk (with or without risk), and control variables (age, gender, health center, education and marital status). Descriptive and association analysis were performed. Odds Ratio (OR) was estimated through simple and multiple regressions logistics. Results 58.7% of the participants reported HIV occupational risk. 63.8% of the participants from the exposed group reported an appropriate level of knowledge, versus 36.1% of the non-exposed group (Adjusted OR of 3.1, IC95%OR: 2.0-4.8, p<0.0001). Technicians and cleaning staff reported a lower proportion of appropriate level of knowledge compared to the employees with college education (p<0.0001). Conclusion The level of HIV/AID occupational risk is directly associated with the level of knowledge of the disease. PMID:25284913

To examine U.S. adult knowledge of the sugar content of sports drinks and whether this knowledge and other characteristics are associated with their sports drink consumption. Nonexperimental. Nationally representative 2011 Summer ConsumerStyles survey data. 3929 U.S. adults. The outcome variable was sports drink consumption in the past 7 days. The main exposure variable was knowledge about sports drinks containing sugar. The covariates were sociodemographic characteristics, physical activity, and weight status. Multivariable logistic regression analysis was used to estimate adjusted odds ratios (ORs) for adults consuming sports drinks ≥1 times/wk after controlling for other characteristics. Approximately 22% of adults reported consuming sports drinks ≥1 times/wk. Most adults (71%) agreed that sports drinks contain sugar; however, this agreement was not significantly associated with adults' sports drink consumption. The odds of drinking sports drinks ≥1 times/wk were significantly higher among younger adults aged 18 to 64 years (OR range: 5.46-2.71), males (OR = 2.09), high-school graduates (OR = 1.52), and highly active adults (OR = 2.09). There were disparities in sports drink consumption by sociodemographic characteristics and physical activity level; however, knowledge of sports drinks' sugar content was not associated with consumption. Understanding why some population groups are higher consumers may assist in the development of education, providing those groups with a better understanding of sports drinks' nutritional value and health consequences of excessive sugar consumption in any form.

The risk of dental trauma may increase during sports participation. The purpose of this study was to evaluate the knowledge, attitude, and practices of sports participants concerning sports-related dental trauma and associated emergency/preventive practices. The study included 124 male subjects over 18 years of age participating in contact and non-contact sports in three clubs in the Eastern Province, Saudi Arabia. A questionnaire was used to assess past experience of dental trauma related to sports in addition to the use of a mouth guard and knowledge of related emergency procedures. Outcomes were compared between individuals practicing direct and non-direct contact sports. One third of the participants had experienced dental trauma while playing sports, mostly crown fracture, mobility, and avulsion. Their knowledge of first aid and emergency procedures was inadequate. A significantly higher proportion of non-direct contact sport participants sought the help of a dentist for themselves or others (P = 0.04 and 0.003, respectively). Only 33.9% used mouth guards, with higher odds of mouth guard use associated with participating in direct contact sports and believing a tooth can be lost during sports practice (odds ratio = 5.59 and 5.37, respectively). Educational programs are needed to increase the awareness in sports participants of the risk of dental trauma during sports participation, to improve their knowledge of first aid procedures, and to increase the use of mouth guards.

Abstract In Taiwan, group tours are a popular mode of international travel; hence, group tour leaders must ensure traveler safety and health. This study identified factors influencing tour leaders’ willingness to recommend pretravel medical consultation and vaccination. A cross-sectional questionnaire survey was administered to tour leaders from January 2011 to December 2012. Multivariate logistic regression analyses were performed to estimate the odds ratios of having a positive attitude and willingness based on different knowledge scores of the tour leaders after adjustments for age, sex, education level, and seniority. Tour leaders with a more detailed knowledge of both travel-related infectious and noninfectious diseases demonstrated a higher willingness to receive vaccination. They believed that consultation at travel clinics before travel can improve travelers’ health (P < .05). This study supports the importance and effectiveness on educating tour leaders’ knowledge about travel-related diseases to improve health care for travelers. PMID:29419678

Hysterectomy is among the most common major surgical procedures performed in women. Approximately 450,000 hysterectomy procedures are performed each year in the United States for benign indications. However, little is known regarding contemporary US hysterectomy trends for women with benign disease with respect to operative technique and perioperative complications, and the association between these 2 factors with patient, surgeon, and hospital characteristics. We sought to describe contemporary hysterectomy trends and explore associations between patient, surgeon, and hospital characteristics with surgical approach and perioperative complications. Hysterectomies performed for benign indications by general gynecologists from July 2012 through September 2014 were analyzed in the all-payer Maryland Health Services Cost Review Commission database. We excluded hysterectomies performed by gynecologic oncologists, reproductive endocrinologists, and female pelvic medicine and reconstructive surgeons. We included both open hysterectomies and those performed by minimally invasive surgery, which included vaginal hysterectomies. Perioperative complications were defined using the Agency for Healthcare Research and Quality patient safety indicators. Surgeon hysterectomy volume during the 2-year study period was analyzed (0-5 cases annually = very low, 6-10 = low, 11-20 = medium, and ≥21 = high). We utilized logistic regression and negative binomial regression to identify patient, surgeon, and hospital characteristics associated with minimally invasive surgery utilization and perioperative complications, respectively. A total of 5660 hospitalizations were identified during the study period. Most patients (61.5%) had an open hysterectomy; 38.5% underwent a minimally invasive surgery procedure (25.1% robotic, 46.6% laparoscopic, 28.3% vaginal). Most surgeons (68.2%) were very low- or low-volume surgeons. Factors associated with a lower likelihood of undergoing minimally invasive surgery included older patient age (reference 45-64 years; 20-44 years: adjusted odds ratio, 1.16; 95% confidence interval, 1.05-1.28), black race (reference white; adjusted odds ratio, 0.70; 95% confidence interval, 0.63-0.78), Hispanic ethnicity (adjusted odds ratio, 0.62; 95% confidence interval, 0.48-0.80), smaller hospital (reference large; small: adjusted odds ratio, 0.26; 95% confidence interval, 0.15-0.45; medium: adjusted odds ratio, 0.87; 95% confidence interval, 0.79-0.96), medium hospital hysterectomy volume (reference ≥200 hysterectomies; 100-200: adjusted odds ratio, 0.78; 95% confidence interval, 0.71-0.87), and medium vs high surgeon volume (reference high; medium: adjusted odds ratio, 0.87; 95% confidence interval, 0.78-0.97). Complications occurred in 25.8% of open and 8.2% of minimally invasive hysterectomies (P < .0001). Minimally invasive hysterectomy (adjusted odds ratio, 0.22; 95% confidence interval, 0.17-0.27) and large hysterectomy volume hospitals (reference ≥200 hysterectomies; 1-100: adjusted odds ratio, 2.26; 95% confidence interval, 1.60-3.20; 101-200: adjusted odds ratio, 1.63; 95% confidence interval, 1.23-2.16) were associated with fewer complications, while patient payer, including Medicare (reference private; adjusted odds ratio, 1.86; 95% confidence interval, 1.33-2.61), Medicaid (adjusted odds ratio, 1.63; 95% confidence interval, 1.30-2.04), and self-pay status (adjusted odds ratio, 2.41; 95% confidence interval, 1.40-4.12), and very-low and low surgeon hysterectomy volume (reference ≥21 cases; 1-5 cases: adjusted odds ratio, 1.73; 95% confidence interval, 1.22-2.47; 6-10 cases: adjusted odds ratio, 1.60; 95% confidence interval, 1.11-2.23) were associated with perioperative complications. Use of minimally invasive hysterectomy for benign indications remains variable, with most patients undergoing open, more morbid procedures. Older and black patients and smaller hospitals are associated with open hysterectomy. Patient race and payer status, hysterectomy approach, and surgeon volume were associated with perioperative complications. Hysterectomies performed for benign indications by high-volume surgeons or by minimally invasive techniques may represent an opportunity to reduce preventable harm. Copyright © 2017 Elsevier Inc.

Hypertension is a health issue affecting adolescents. Accumulating evidence affirms that elevated blood pressure begins in childhood and tracks into adulthood. This cross-sectional study was conducted to determine the prevalence of elevated blood pressure and its predictors among secondary school students in Sarawak, Malaysia. A total of 2,461 secondary school students aged 12-17 years from 19 schools in Sarawak participated in the study. Questionnaire was used to obtain socio-demographic data, parental history of hypertension, and self-reported physical activity. Anthropometric and blood pressure measurements were taken. Data was entered and analysed using SPSS version 23.0. The prevalence of adolescents with elevated blood pressure, overweight, central obesity, and overfat were 30.1%, 24.3%, 13.5%, and 6.7%, respectively. Multivariate logistic regression demonstrated the predictors significantly associated with elevated blood pressure among respondents: overweight (adjusted odds ratio=3.144), being male (adjusted odds ratio=3.073), being Chinese (adjusted odds ratio=2.321) or Iban (adjusted odds ratio=1.578), central obesity (adjusted odds ratio=2.145), being overfat (adjusted odds ratio=1.885), and being an older adolescent (adjusted odds ratio=1.109). Parental history of hypertension, locality, and physical activity showed no significant associations. The obesity epidemic must be tackled at community and school levels by health education and regulation of school canteen foods. Copyright© by the National Institute of Public Health, Prague 2018.

Around the world, more than three million newborns die in their first months of life every year. In Ethiopia during the last five years period; neonatal mortality is 37 deaths per 1000 live births. Even though there is an improvement compared to the past five years, there is still high home delivery 90 %, and high neonatal mortality about the Millennium Development Goal, which aims to be less than 32/1000 live births in Ethiopia. The purpose of this study is to assess maternal knowledge, practice and associated factors of essential newborn care at home in Gulomekada District Eastern Tigray, Ethiopia. A community-based cross-sectional study is conducted in 296 mothers from Gulomekada District by using simple random sampling technique. Data entry and analysis is carried out by using Statistical Package for Social Sciences-20. The magnitude of the association between different variables about the outcome variable is measured by odds ratio with 95 % confidence interval. A binary logistic regression analysis is made to obtain odds ratio and the confidence interval of statistical associations. The goodness of fit had tested by Hosmer-Lemeshow statistic and all variables with P-value greater than 0.05 are fitted to the multivariate model. Variables with P < 0.2 in the bivariate analysis are included in the final model, and statistical significance is declared at P < 0.05. Eighty percent (80.4 %) study participants had good knowledge on essential new born care and 92.9 % had the good practice of essential new born care. About 60 % of mothers applied butter or oil on the cord stump for their last baby. Marital status and education are significantly associated with knowledge, whereas urban residence mothers with good knowledge on essential newborn care and employed mothers are significantly associated with mothers' practice of essential newborn care. Almost all mothers know and practice essential newborn care correctly except oil or butter application to the cord stump is highly practiced which should be avoided. Only marital status and educational status are significantly associated with mothers' knowledge.

Our aim was to evaluate obesity risk knowledge, weight misperception, and diet and health-related attitudes among women intending to become pregnant compared to those not intending to become pregnant. We conducted a cross-sectional survey of health behaviors, including obesity risk knowledge, weight misperception, and diet and health-related attitudes among women (aged 16 to 40 years) attending reproductive health clinics in southeast Texas. Data were collected through self-administered questionnaires and chart review. Multivariable logistic regression analyses were performed to examine the association between pregnancy intention and obesity risk knowledge, weight misperception, and health-related attitudes after adjusting for age, race, income, and gravidity. Overall, 1,726 women completed the survey, of which 1,420 responded to a question on pregnancy intention. Of these, 126 stated they were intending to become pregnant. Obesity risk knowledge (adjusted odds ratio=1.14; 95% confidence interval [CI] 0.74 to 1.77) and weight misperception (adjusted odds ratio=1.17; 95% CI 0.75 to 1.83) did not differ between women intending and not intending to become pregnant. In addition, diet and health-related attitudes did not differ between these two groups (P>0.05 for all). Among women intending to become pregnant, 51% had low obesity risk knowledge and 31% misperceived their body weight. Further, 76% of these women felt confused about what constitutes a healthy diet, although 47% believed that their current diet was healthy and saw no reason to change their current eating patterns. While weight misperception did not differ significantly between the two groups, overweight women intending to become pregnant were more likely to misperceive their weight than obese women intending to become pregnant (71% vs 10%; P<0.001). There is a need for improved preconception counseling, especially for women intending to become pregnant, regarding the risks associated with being overweight or obese, misperception of body weight, and negative diet and health-related attitudes.

A key strategy to reduce unintended adolescent pregnancies is to expand access to long-acting reversible contraceptive (LARC) methods, including intrauterine devices and subdermal contraceptive implants. LARC services can be provided to adolescents in school-based health and other primary care settings, yet limited knowledge and negative attitudes about LARC methods may influence adolescents' utilization of these methods. This study aimed to evaluate correlates of knowledge and acceptability of LARC methods among adolescent women at a school-based health center (SBHC). In this cross-sectional study, female patients receiving care at 2 SBHCs in Seattle, Washington completed an electronic survey about sexual and reproductive health. Primary outcomes were (1) LARC knowledge as measured by percentage correct of 10 true-false questions and (2) LARC acceptability as measured by participants reporting either liking the idea of having an intrauterine device (IUD)/subdermal implant or currently using one. A total of 102 students diverse in race/ethnicity and socioeconomic backgrounds completed the survey (mean age 16.2 years, range 14.4-19.1 years). Approximately half reported a lifetime history of vaginal sex. Greater LARC knowledge was associated with white race (regression coefficient [coef] = 26.8; 95% CI 13.3-40.4; P < .001), history of vaginal intercourse (coef = 29.9; 95% CI 17.1-42.7; P < .001), and current/prior LARC use (coef = 22.8; 95% CI 6.5-40.0; P = .007). Older age was associated with lower IUD acceptability (odds ratio = 0.53, 95% CI 0.30-0.94; P = .029) while history of intercourse was associated with greater implant acceptability (odds ratio 5.66, 95% CI 1.46-22.0; P = .012). Adolescent women in this SBHC setting had variable knowledge and acceptability of LARC. A history of vaginal intercourse was the strongest predictor of LARC acceptability. Our findings suggest a need for LARC counseling and education strategies, particularly for young women from diverse cultural backgrounds and those with less sexual experience. © The Author(s) 2016.

This analysis aimed at examining the association between the level of knowledge about long-acting/permanent methods of contraceptives (LAPM) and nonuse of LAPM among currently married, nonpregnant, and fecund women aged 15 to 49 years intending to limit childbearing. Data were derived from a cross-sectional study in Tuban, Kediri, and Lumajang District (East Java Province) and Lombok Barat, Lombok Timur, and Sumbawa District (Nusa Tenggara Barat Province) in June 2012. Information was obtained from 4323 respondents. Using multivariate logistic regression, we found that women with moderate levels of LAPM knowledge were less likely to use LAPM than women with high levels of knowledge (adjusted odds ratio [aOR] = 2.01, 95% CI = 1.51-2.68). Women with low level of LAPM knowledge were less likely to use LAPM than women with high levels of knowledge (aOR = 4.25, 95% CI = 3.37-5.36). Efforts to strengthen counseling services and increased provider knowledge and counselling skills are important to improve women's knowledge about and use of LAPM.

Race, class and gender in engineering education: A quantitative investigation of first year enrollment

NASA Astrophysics Data System (ADS)

Phillips, Canek Moises Luna

Research explanations for the disparity across both race and gender in engineering education has typically relied on a deficit model, whereby women and people of color lack the requisite knowledge or psychological characteristics that Whites and men have to become engineers in sufficient numbers. Instead of using a deficit model approach to explain gender and race disparity, in the three studies conducted for this dissertation, I approach gender and race disparity as the result of processes of segregation linked to the historic and on-going perpetuation of systemic sources of oppression in the United States. In the first study, I investigate the relationship between the odds ratios of women and men enrolled in first year US engineering programs and institutional characteristics. To do this, I employ linear regression to study data from the American Society of Engineering Education (ASEE) and the National Center for Education Statistics (NCES) to quantify relationships between odds ratios and institutional characteristics. Results of the linear regression models showed significant relationships between the cost of universities and university selectivity and the odds ratios of women choosing engineering. I theorize how the results could be related to the operation of occupational segregation in engineering, particularly how class-based markers have been historically used by women to overcome gender-based segregation in engineering. In the second study, I examine longitudinal patterns of race, gender, and intersectional combinations of race and gender in enrollments of students in first year engineering programs across the United States (US). Using enrollment data from the American Society of Engineering Education and California Post-Secondary Education Commission, I construct measures of segregation to study how trends in the disparity of students by race could be related to increases in public school segregation nationally over the past 25 years. I found that as public school segregation levels increased nationally, underrepresentation of Black and Hispanics and overrepresentation of White and Asian students has moved further toward the extremes in first year engineering programs compared to these groups’ shares of high school enrollment. I conclude that the study of public school segregation and its effect on racial disparity needs greater attention, as well as that the investigation I conducted serves as a beginning towards pushing back on deficit model explanations of race and gender disparity in engineering. In the third study, I return to the investigation of odds ratios and institutional characteristics, constructing odds ratios using ASEE and NCES data based on the odds of enrollment in first year engineering programs between Asian, Black, and Hispanic students compared to White students. I again quantify the relationships between odds ratios and institutional characteristics using linear regression models and discuss results using theory based in the perspective of occupational segregation. In this case, results were inconclusive leading me to conclude that other variables that I did not consider, such as the segregation levels of schools that students come from before enrollment, should be considered as I develop my own future study into the topic.

Compound depressed skull fracture (DSF) is a neurosurgical emergency. Preoperative knowledge of dural status is indispensable for treatment decision making. This study aimed to determine predictors of dural tear from clinical and imaging characteristics in patients with compound DSF. This prospective, multicenter correlational study in neurosurgical hospitals in Addis Ababa, Ethiopia, included 128 patients operated on from January 1, 2016, to October 31, 2016. Clinical, imaging, and intraoperative findings were evaluated. Univariate and multivariate analyses were used to establish predictors of dural tear. A logistic regression model was developed to predict probability of dural tear. Model validation was done using the receiver operating characteristic curve. Dural tear was seen in 55.5% of 128 patients. Demographics, injury mechanism, clinical presentation, and site of DSF had no significant correlation with dural tear. In univariate and multivariate analyses, depth of fracture depression (odds ratio 1.3, P < 0.001), pneumocephalus (odds ratio 2.8, P = 0.005), and brain contusions/intracerebral hematoma (odds ratio 5.5, P < 0.001) were significantly correlated with dural tear. We developed a logistic regression model (diagnostic test) to calculate probability of dural tear. Using the receiver operating characteristic curve, we determined the cutoff value for a positive test giving the highest accuracy to be 30% with a corresponding sensitivity of 93.0% and specificity of 43.9%. Dural tear in compound DSF can be predicted with 93.0% sensitivity using preoperative findings and may guide treatment decision making in resource-limited settings where risk of extensive cranial surgery outweighs the benefit.

Predictors and outcome of surgical repair of obstetric fistula at a regional referral hospital, Mbarara, western Uganda

PubMed Central

2011-01-01

Background Obstetric fistula although virtually eliminated in high income countries, still remains a prevalent and debilitating condition in many parts of the developing world. It occurs in areas where access to care at childbirth is limited, or of poor quality and where few hospitals offer the necessary corrective surgery. Methods This was a prospective observational study where all women who attended Mbarara Regional Referral Hospital in western Uganda with obstetric fistula during the study period were assessed pre-operatively for social demographics, fistula characteristics, classification and outcomes after surgery. Assessment for fistula closure and stress incontinence after surgery was done using a dye test before discharge Results Of the 77 women who were recruited in this study, 60 (77.9%) had successful closure of their fistulae. Unsuccessful fistula closure was significantly associated with large fistula size (Odds Ratio 6 95% Confidential interval 1.46-24.63), circumferential fistulae (Odds ratio 9.33 95% Confidential interval 2.23-39.12) and moderate to severe vaginal scarring (Odds ratio 12.24 95% Confidential interval 1.52-98.30). Vaginal scarring was the only factor independently associated with unsuccessful fistula repair (Odds ratio 10 95% confidential interval 1.12-100.57). Residual stress incontinence after successful fistula closure was associated with type IIb fistulae (Odds ratio 5.56 95% Confidential interval 1.34-23.02), circumferential fistulae (Odds ratio 10.5 95% Confidential interval 1.39-79.13) and previous unsuccessful fistula repair (Odds ratio 4.8 95% Confidential interval 1.27-18.11). Independent predictors for residual stress incontinence after successful fistula closure were urethral involvement (Odds Ratio 4.024 95% Confidential interval 2.77-5.83) and previous unsuccessful fistula repair (Odds ratio 38.69 95% Confidential interval 2.13-703.88). Conclusions This study demonstrated that large fistula size, circumferential fistulae and marked vaginal scarring are predictors for unsuccessful fistula repair while predictors for residual stress incontinence after successful fistula closure were urethral involvement, circumferential fistulae and previous unsuccessful fistula repair.

Telephone hotlines are a widely used type of suicide prevention program. The aim of this study was to clarify the risk factors for suicidal ideation by investigating its association with a number of characteristics among telephone hotline callers. Data were collected over a 10-year period from a total of 246,595 calls to Inochi No Denwa, a telephone crisis hotline in Ibaraki, Japan, and subsequently analyzed. Odds ratios for suicidal compared with nonsuicidal ideation were also calculated. About 6% of the calls to the hotline were suicide related, and about 2% of the callers had attempted suicide in the past. Odds ratios for suicidal ideation increased during winter, but no daily tendencies were evident. Those whose problems were related to their way of life were at the highest risk of suicidal ideation, followed by those with health-related concerns. We were able to identify risk factors for suicidal ideation based on an analysis of enormous amounts of data from a telephone crisis hotline in Japan. Knowledge of these risk factors is expected to lead to improvements in suicide prevention programs.

To examine the associations with symptoms of 1) burnout and 2) work-related posttraumatic stress, in adult and pediatric intensive care staff, focusing on the particular contributions of resilience and coping strategies. Point prevalence cross-sectional study. Three adult ICUs and four PICUs. Three hundred seventy-seven ICU staff. None. Brief Resilience Scale, abbreviated Maslach Burnout Inventory, Trauma Screening Questionnaire, and Hospital Anxiety and Depression Scale. Prevalence of burnout (defined as high emotional exhaustion or high depersonalization) was 37%. Prevalence of clinically significant posttraumatic stress symptoms was 13%. There was a degree of overlap between burnout and other measures of distress, most notably for anxiety (odds ratio, 10.56; 95% CI, 4.12-27.02; p < 0.001). Hierarchical logistic regression demonstrated that self-reported resilience was strongly associated with decreased likelihood of meeting criteria for both forms of work-related distress (burnout: odds ratio, 0.52; 95% CI, 0.36-0.74; p < 0.001 and posttraumatic stress: odds ratio, 0.28; 95% CI, 0.16-0.46; p < 0.001) and that physicians were twice as likely as nurses to be at risk of reporting burnout (odds ratio, 2.11; 95% CI, 1.18-3.78; p = 0.012). After controlling for resilience, profession, and setting, the following coping strategies were independently associated with outcomes: attending debriefing reduced risk of burnout (odds ratio, 0.45; 95% CI, 0.21-0.95; p = 0.036), whereas the odds of posttraumatic stress were less if staff used talking to seniors (odds ratio, 0.43; 95% CI, 0.20-0.92; p = 0.029) or hobbies (odds ratio, 0.46; 95% CI, 0.23-0.93; p = 0.030) to cope with stress at work. Venting emotion (odds ratio, 1.92; 95% CI, 1.12-3.31; p = 0.018) and using alcohol (odds ratio, 2.30; 95% CI, 1.26-4.20; p = 0.006) were associated with a doubling in risk of reporting burnout. The use of particular coping strategies was systematically associated with symptoms of burnout and work-related posttraumatic stress in this group of intensive care staff, even after controlling for resilience and other factors. More research on how best to promote adaptive coping is needed in these challenging settings.

Religious hospital policies on reproductive care: what do patients want to know?

Religious hospitals are a large and growing part of the American healthcare system. Patients who receive obstetric and other reproductive care in religious hospitals may face religiously-based restrictions on the treatment their doctor can provide. Little is known about patients' knowledge or preferences regarding religiously restricted reproductive healthcare. We aimed to assess women's preferences for knowing a hospital's religion and religiously based restrictions before deciding where to seek care and the acceptability of a hospital denying miscarriage treatment options for religious reasons, with and without informing the patient that other options may be available. We conducted a national survey of women aged 18-45 years. The sample was recruited from AmeriSpeak, a probability-based research panel of civilian noninstitutionalized adults. Of 2857 women invited to participate, 1430 completed surveys online or over the phone, for a survey response rate of 50.1%. All analyses adjusted for the complex sampling design and were weighted to generate estimates representative of the population of US adult reproductive-age women. We used χ 2 tests and multivariable logistic regression to evaluate associations. One third of women aged 18-45 years (34.5%) believe it is somewhat or very important to know a hospital's religion when deciding where to get care, but 80.7% feel it is somewhat or very important to know about a hospital's religious restrictions on care. Being Catholic or attending religious services more frequently does not make one more or less likely to want this information. Compared with Protestant women who do not identify as born-again, women of other religious backgrounds are more likely to consider it important to know a hospital's religious affiliation. These include religious minority women (adjusted odds ratio, 2.17; 95% confidence interval, 1.11-4.27), those who reported no religion/atheist/agnostic (adjusted odds ratio, 2.27; 95% confidence interval, 1.19-4.34), and born-again Protestants (adjusted odds ratio, 2.38; 95% confidence interval, 1.32-4.28). Religious minority women (adjusted odds ratio, 2.36; 95% confidence interval, 1.01-5.51) and those who reported no religion/atheist/agnostic (adjusted odds ratio, 3.16; 95% confidence interval, 1.42-7.04) were more likely to want to know a hospital's restrictions on care. More than two thirds of women find it unacceptable for the hospital to restrict information and treatment options during miscarriage based on religion. Women who attended weekly religious services were significantly more likely to accept such restrictions (adjusted odds ratio, 3.13; 95% confidence interval, 1.70-5.76) and to consider transfer to another site an acceptable solution (adjusted odds ratio, 3.22; 95% confidence interval, 1.69-6.12). The question, "When should a religious hospital be allowed to restrict care based on religion?" was asked, and 52.3% responded never; 16.6%, always; and 31.1%,"under some conditions. The vast majority of adult American women of reproductive age want information about a hospital's religious restrictions on care when deciding where to go for obstetrics/gynecology care. Growth in the US Catholic health care sector suggests an increasing need for transparency about these restrictions so that women can make informed decisions and, when needed, seek alternative providers.

To assess associations between extent of travel for business and health. Associations between business travel and cardiovascular disease risk factors were assessed using medical record data from 13,057 patients provided by EHE International, Inc. Compared with light travelers (1 to 6 nights per month), nontravelers were more likely to report poor/fair health (odds ratio = 1.58; 95% confidence interval [CI]: 1.33 to 1.87) and the odds ratios increased with increasing travel, reaching 2.61 (95% CI: 1.57 to 4.33) among extensive travelers (>20 nights per month). Compared with light travelers, the odds ratios for obesity were highest among nontravelers (odds ratio = 1.33; 95% CI: 1.18 to 1.50) and extensive travelers (odds ratio = 1.92; 95% CI: 1.25 to 2.94). Although the differences were small, nontravelers and extensive travelers had the highest diastolic blood pressure and lowest high-density lipoprotein cholesterol levels. Poor self-rated health and obesity are associated with extensive business travel.

The purpose of this study was to identify risk factors that are associated with the breakdown of perineal laceration repair in the postpartum period. We conducted a retrospective, case-control study to review perineal laceration repair breakdown in patients who were delivered between September 1995 and February 2005 at the University of Michigan. Bivariate analysis with chi-square test and t-test and stepwise logistic regression analysis were performed. Fifty-nine cases and 118 control deliveries were identified from a total of 14,124 vaginal deliveries. Risk factors were longer second stage of labor (142 vs 87 minutes; P = .001), operative vaginal delivery (odds ratio, 3.6; 95% CI, 1.8-7.3), mediolateral episiotomy (odds ratio, 6.9; 95% CI, 2.6-18.7), third- or fourth-degree laceration (odds ratio, 3.1; 95% CI, 1.5-6.4), and meconium-stained amniotic fluid (odds ratio, 3.0; 95% CI, 1.1-7.9). Previous vaginal delivery was protective (odds ratio, 0.38; 95% CI, 0.18-0.84). Logistic regression showed the most significant factor to be an interaction between operative vaginal delivery and mediolateral episiotomy (odd ratio, 6.36; 95% CI, 2.18-18.57). The most significant events were mediolateral episiotomy, especially in conjunction with operative vaginal delivery, third- and fourth-degree lacerations, and meconium.

Primary repair of penetrating colon injuries is an appealing management option; however, uncertainty about its safety persists. This study was conducted to compare the morbidity and mortality of primary repair with fecal diversion in the management of penetrating colon injuries by use of a meta-analysis of randomized, prospective trials. We searched for prospective, randomized trials in MEDLINE (1966 to November 2001), the Cochrane Library, and EMBase using the terms colon, penetrating, injury, colostomy, prospective, and randomized. Studies were included if they were randomized, controlled trials that compared the outcomes of primary repair with fecal diversion in the management of penetrating colon injuries. Five studies were included. Reviewers performed data extraction independently. Outcomes evaluated from each trial included mortality, total complications, infectious complications, intra-abdominal infections, wound complications, penetrating abdominal trauma index, and length of stay. Peto odds ratios for combined effect were calculated with a 95 percent confidence interval for each outcome. Heterogeneity was also assessed for each outcome. The penetrating abdominal trauma index of included subjects did not differ significantly between studies. Mortality was not significantly different between groups (odds ratio, 1.70; 95 percent confidence interval, 0.51-5.66). However, total complications (odds ratio, 0.28; 95 percent confidence interval, 0.18-0.42), total infectious complications (odds ratio, 0.41; 95 percent confidence interval, 0.27-0.63), abdominal infections including dehiscence (odds ratio, 0.59; 95 percent confidence interval, 0.38-0.94), abdominal infections excluding dehiscence (odds ratio, 0.52; 95 percent confidence interval, 0.31-0.86), wound complications including dehiscence (odds ratio, 0.55; 95 percent confidence interval, 0.34-0.89), and wound complications excluding dehiscence (odds ratio, 0.43; 95 percent confidence interval, 0.25-0.76) all significantly favored primary repair. Meta-analysis of currently published randomized, controlled trials favors primary repair over fecal diversion for penetrating colon injuries.

Severe anemia is a major cause of sickness and death in African children, yet the causes of anemia in this population have been inadequately studied. We conducted a case-control study of 381 preschool children with severe anemia (hemoglobin concentration, <5.0 g per deciliter) and 757 preschool children without severe anemia in urban and rural settings in Malawi. Causal factors previously associated with severe anemia were studied. The data were examined by multivariate analysis and structural equation modeling. Bacteremia (adjusted odds ratio, 5.3; 95% confidence interval [CI], 2.6 to 10.9), malaria (adjusted odds ratio, 2.3; 95% CI, 1.6 to 3.3), hookworm (adjusted odds ratio, 4.8; 95% CI, 2.0 to 11.8), human immunodeficiency virus infection (adjusted odds ratio, 2.0; 95% CI, 1.0 to 3.8), the G6PD -202/-376 genetic disorder (adjusted odds ratio, 2.4; 95% CI, 1.3 to 4.4), vitamin A deficiency (adjusted odds ratio, 2.8; 95% CI, 1.3 to 5.8), and vitamin B 12 deficiency (adjusted odds ratio, 2.2; 95% CI, 1.4 to 3.6) were associated with severe anemia. Folate deficiency, sickle cell disease, and laboratory signs of an abnormal inflammatory response were uncommon. Iron deficiency was not prevalent in case patients (adjusted odds ratio, 0.37; 95% CI, 0.22 to 0.60) and was negatively associated with bacteremia. Malaria was associated with severe anemia in the urban site (with seasonal transmission) but not in the rural site (where malaria was holoendemic). Seventy-six percent of hookworm infections were found in children under 2 years of age. There are multiple causes of severe anemia in Malawian preschool children, but folate and iron deficiencies are not prominent among them. Even in the presence of malaria parasites, additional or alternative causes of severe anemia should be considered.

Extracorporeal cardiopulmonary resuscitation appears to improve survival in patients with acute refractory cardiopulmonary failure. This analysis was performed to determine survival outcomes and predictors of in-hospital mortality for term and preterm neonates who received extracorporeal cardiopulmonary resuscitation. Retrospective review of data from the Extracorporeal Life Support Organization international registry. Pediatric and neonatal ICUs. Infants less than or equal to 30 days. Extracorporeal cardiopulmonary resuscitation. Demographic, clinical, and survival data from patients who received extracorporeal cardiopulmonary resuscitation between 1998 and 2010 were analyzed to determine factors that affect in-hospital mortality. Overall survival to hospital discharge for the 641 neonates who received extracorporeal cardiopulmonary resuscitation was 39%. In univariate analysis, gestational age correlated inversely with stroke (odds ratio, 0.84 [95% CI, 0.75-0.95]; p = 0.006) and death (odds ratio, 0.87 [95% CI, 0.78-0.96]; p = 0.005) as did corrected gestational age (odds ratio, 0.89 [95% CI, 0.81-0.97]; p = 0.006) and birth weight (odds ratio, 0.53 [95% CI, 0.38-0.74]; p < 0.001). Dysrhythmia as the primary diagnosis had significantly lower odds of death than single-ventricle cardiac disease (odds ratio, 0.24 [95% CI, 0.06-0.95]; p = 0.04). Higher pre-extracorporeal cardiopulmonary resuscitation oxygenation decreased the odds of death (odds ratio, 0.996 [95% CI, 0.994-0.999]; p = 0.01), whereas complications occurring on extracorporeal life support increased the odds of death. In the multivariate analysis, lower birth weight and pre-extracorporeal cardiopulmonary resuscitation oxygenation, as well as complications including CNS hemorrhage, pulmonary hemorrhage, acidosis, renal replacement therapy, and mechanical complications, increased the odds of death. Overall survival for neonates receiving extracorporeal cardiopulmonary resuscitation is similar to older pediatric patients but decreases with lower gestational age and weight. Despite this, many low-birth weight neonates survive to hospital discharge.

This study looks at women from the slums in Mohammadpur, Dhaka, Bangladesh, where 54 percent of women's BMI was less than 18.5. Fifty percent of the Dhaka slum population lived below the poverty line. Logistic regression showed that women with income above 1,500 taka per capita were 1.78 times more likely to have a higher BMI (odds ratio 1.7863; CI = 0.671-3.639). Women with their own savings were 1.89 times more likely to have higher BMI (odds ratio 1.879; CI = 0.01163-1.6431). Women were 4.5 times more likely to have a higher BMI when food expenditure per capita above 559 taka per month (odds ratio 4.55; CI = 1.0302-8.0799). Women were 1.82 times more likely to have higher BMI when there was a break even situation in financial status (odds ratio 1.8212; CI = -015709-3.6285). Female headed households were 3.3 times more likely to have a higher BMI compared to women living in male headed households (odds ratio 3.2966; CI = 0.33711-6.25620). Women who work 15-23 days per month were 2.3 times more likely to have a higher BMI (odds ratio 2.33; CI = 0.1133-4.5600). Women who are the budget manager are 1.12 times more likely to have a higher BMI (odds ratio 1.125; CI = 0.29296-2.0966). Where as a husband who beats his wife is 1.83 more likely to have a poorer BMI (odds ratio 1.8312; CI = -3.72596-0.17508). Women who have no marriage documents and women who take days off due to illness less than 11 days per month were more likely to have a poorer BMI (odds ratio 0.5567; CI = -0.049339-2.8379; odds ratio 0.7569; CI = 0.183167-2.0002). Women's nutritional status and well being can influence their ability to provide for themselves and their families and the demonstration of a relationship between measures of women's autonomy and control in the household and women's nutritional status is an important indication of the importance of these sociological constructs. Women's participation in work outside the home may be a factor increasing their autonomy. The identification of relationships between women's autonomy and control and their physical well being should provide further leverage for policy change that will enable women to escape some traditional roles and to contribute as more equal partners with men in the future of Bangladeshi society.

The adherence of program participants to periodic vitamin A capsule (VAC) supplementation among children aged 1-5 years (n = 677) in Central Java, Indonesia was assessed. Fourteen villages from five sub-districts and one ward from one sub-district in Central Java were included in the study to represent rural and suburban areas. All questions about demographic factors, socioeconomic conditions, current dietary practice and healthcare-seeking attitudes for common childhood illnesses, previous breastfeeding experience, their knowledge about vitamin A and adherence to the VAC program after capsule distribution (two periods in 2000) were asked. Caretakers with limited knowledge about the health benefits of vitamin A, households with more than one preschool child, and households with older children (> 36 months) were associated with a decreased likelihood of regular participation in the program with odds ratios of 0.38, 0.55, and 0.26, respectively (p < 0.01). The percentage of caretakers who utilized community health centers, village health posts or midwives' practices in rural areas, was significantly higher (86.6 per cent, p < 0.001) than in suburban areas (62.8 per cent). Living in a rural location was associated with an increased adherence to participate in the program regularly with an odds ratio of 2.02 (p < 0.01). In conclusion, nutritional education and periodic social marketing should be re-emphasized and other potential delivery channels, such as private healthcare practices, could also contribute to an increase adherence of supplementation program.

We studied 45 full-term newborns divided into 3 groups. Group 1: 17 newborns with bilirubin <10 mg/dL; Group 2: 18 newborns with hemolytic ictericia (bilirubin 11-20 mg/dL) and Group 3: 10 newborns with moderate hemolytic ictericia needing exchange transfusion. The following were studied: erythrocytic deformability, plasma viscosity, plasmatic osmolarity, seric bilirubin, bilirubin/albumin ratio, free fatty acids and corpuscular volume of the erythrocytes. In full-term newborns, the following are risk factors for increased erythrocytic rigidity: neonatal hemolytic illness (p = 0.004, odds ratio: 7.02), increases in total bilirubin (p = 0.02, odds ratio: 4.3) and increases in the bilirubin/albumin ratio (p = 0.025, odds ratio: 4.25). Furthermore, the most important risk factor for high plasma viscosity is also neonatal hemolytic illness (p = 0.01, odds ratio: 2.30). The role of total bilirubin is also important (p = 0.09, odds ratio: 2.10), while that of the bilirubin/albumin ratio (p = 0.012, NS) is less so. The greater the hemolysis, the greater the erythrocytic rigidity and plasma viscosity (p < 0.01). In full-term newborns with moderate ictericia, hemolytic illness and increases in the bilirubin/albumin ratio are accompanied by rheological alterations that could affect cerebral microcirculation and cause a neurological deficit not exclusively related to the levels of bilirubin in plasma.

Objectives. We monitored changes in self-reported knowledge, attitudes, and behaviors regarding fruit and vegetable consumption in Western Australia prior to and after a healthful-eating campaign. Methods. We obtained telephone survey data from 2854 adults in Perth from Nutrition Monitoring Surveys conducted in 1995, 1998, 2001, and 2004. The “Go for 2&5” fruit and vegetable campaign was implemented from 2002 to 2005. Results. We observed changes in knowledge, attitudes, and behaviors regarding fruit and vegetable intake. In 2004, respondents were more likely than in 1995 to report 2 servings of fruit (odds ratio [OR] = 3.66; 95% confidence interval [CI] = 2.85, 4.70) and 5 servings of vegetables (OR = 4.50; 95% CI = 3.49, 5.80) per day as optimal. Despite this, vegetable consumption in 2004 was less than in 1995 (rate ratio = 0.88; 95% CI = 0.82, 0.96; P = .003). Perceived adequacy of vegetable (59.3%) or fruit (34.5%) intake and insufficient time for vegetable preparation (14.3%) were the main barriers. Conclusions. Knowledge of the recommended fruit and vegetable intake increased following the Go for 2&5 campaign. Perceptions of the adequacy of current intake and time scarcity should be considered when designing nutrition interventions. PMID:19059859

To investigate the effect of general or regional anesthesia on postoperative cardiopulmonary complications and inpatient mortality after hip fracture surgery in elderly patients. A retrospective analysis was conducted according to the medical records of 572 elderly patients with hip fractures admitted to our hospital from January 1, 2005 to December 31, 2014. The age, gender, preoperative comorbidities, length of preoperative bedridden time, mechanism of injury, surgical types, anesthetic methods, major postoperative complications and inpatient mortality were recorded. Multivariate Logistic regression analysis was applied to analyze the impact of different anesthetic methods on inpatient mortality in these patients. Of the 572 patients, 392 (68.5%) received regional anesthesia. Inpatient death occurred in 8 (8/572, mortality: 1.4%), including 5 cases of RA group (5/392, mortality: 1.3%) and 3 cases of GA group (3/180, mortality: 1.7%). There was no statistically significant difference between the two groups in inpatient mortality (P>0.05). Multiple Logistic regression analysis showed that gender (odds ratio: 0.18, 95% CI: 0.03-1.05, P=0.057), age (odds ratio: 1.22, 95% CI: 1.07-1.38, P=0.002), preoperative pulmonary comorbidities (odds ratio: 12.09, 95% CI: 2.28-64.12, P=0.003) and surgical types (odds ratio: 9.36, 95% CI: 1.34-64.26, P=0.024) were risk factors for inpatient mortality. Postoperative cardiovascular complications occurred in 36 patients (36/572, morbidity: 6.3%), with 19 patients in RA group (19/392, morbidity: 4.8%),and 17 patients in GA group (17/180, morbidity: 9.4%). Multiple Logistic regression analysis showed that age (odds ratio: 1.13, 95% CI: 1.07-1.19, P<0.001), hypertension (odds ratio: 2.72, 95% CI: 1.24-5.96, P=0.012) and preoperative cerebral comorbidities (odds ratio: 2.11, 95% CI: 0.99-4.52, P=0.054) were risk factors for postoperative cardiovascular complications. Postoperative pulmonary complications occurred in 56 patients (56/572, morbidity: 9.8%), with 19 patients in RA group (19/392, morbidity: 4.8%), and 37 patients in GA group (37/180, morbidity: 20.6%). Multiple Logistic regression analysis showed that age (odds ratio: 1.13, 95% CI: 1.07-1.19, P<0.001), preoperative pulmonary comorbidities (odds ratio: 2.89, 95% CI: 1.28-7.05, P=0.020), length of preoperative bedridden time (odds ratio: 1.11, 95% CI: 1.04-1.18, P=0.003) and anesthetic methods (odds ratio: 5.86, 95% CI: 2.98-11.53, P<0.001) were risk factors for postoperative pulmonary complications. General anesthesia may not affect the inpatient mortality after hip fracture surgery in elderly patients. Regional anesthesia is associated with a lower risk of pulmonary complications after surgical procedure compared with general anesthesia.

Purpose To assess the impact of the education program of the Eye Care Quality and Accessibility Improvement in the Community (EQUALITY) telemedicine program on at-risk patients’ knowledge about glaucoma and attitudes about eye care as well as to assess patient satisfaction with EQUALITY. Patients and methods New or existing patients presenting for a comprehensive eye exam (CEE) at one of two retail-based primary eye clinics were enrolled based on ≥1 of the following at-risk criteria for glaucoma: African Americans ≥40 years of age, Whites ≥50 years of age, diabetes, family history of glaucoma, and/or preexisting diagnosis of glaucoma. A total of 651 patients were enrolled. A questionnaire was administered prior to the patients’ CEE and prior to the patients receiving any of the evidence-based eye health education program; a follow-up questionnaire was administered 2–4 weeks later by phone. Baseline and follow-up patient responses regarding knowledge about glaucoma and attitudes about eye care were compared using McNemar’s test. Logistic regression models were used to assess the association of patient-level characteristics with improvement in knowledge and attitudes. Overall patient satisfaction was summarized. Results At follow-up, all patient responses in the knowledge and attitude domains significantly improved from baseline (P≤0.01 for all questions). Those who were unemployed (odds ratio =0.63, 95% confidence interval =0.42–0.95, P=0.026) or had lower education (odds ratio =0.55, 95% confidence interval =0.29–1.02, P=0.058) were less likely to improve their knowledge after adjusting for age, sex, race, and prior glaucoma diagnosis. This association was attenuated after further adjustment for other patient-level characteristics. Ninety-eight percent (n=501) of patients reported being likely to have a CEE within the next 2 years, whereas 63% (n=326) had a CEE in the previous 2 years. Patient satisfaction with EQUALITY was high (99%). Conclusion Improved knowledge about glaucoma and a high intent to pursue eye care may lead to improved detection of early disease, thus lowering the risk of blindness. PMID:27274329

Objective To characterize adults with spinal cord injury (SCI) who seek oral health information online, and investigate whether seeking oral health information online is associated with oral health knowledge and behaviors. Methods An online oral health survey was posted on the South Carolina Spinal Cord Injury Association website. Respondents were 192 adult residents of the US ages 19–83 years who identified themselves as having SCI occurring at least 1 year before the survey date. Results About 12% (n = 23) of the respondents searched oral health information online in the past 12 months. Significant associations between the proportion of respondents who searched for oral health information online and socio-demographic and the proportion of respondents who engaged in various oral health behaviors were not detected. However, multivariable logistic regression indicated that respondents who searched oral health information online in the past 12 months have 3.4 times the odds of possessing adequate oral health knowledge compared to respondents who did not search oral health information online (adjusted odds ratio = 3.41, 95% confidence interval = 1.35, 8.62, P = 0.01). Conclusions Given the significant association between seeking oral health information online and adequate oral health knowledge, this study suggests that online oral health information may be a potential avenue for dental health professionals to supplement oral health education in adults with SCI.

Overdose deaths tripled between 1999 and 2014. Most fatal overdoses are witnessed, offering an opportunity for bystanders to call 911. However, fear of arrest may prevent them from calling authorities. Many states have passed 911 Good Samaritan laws that protects the 911 caller and overdose victim from prosecution for drug possession. Little is known, however, about whether the law affects 911-calling behavior of overdose witnesses. This study investigated the relationship between knowledge of a 911 Good Samaritan Law (GSL) and 911-calling behavior of study participants trained in opioid overdose rescue. 351 individuals (N = 351) trained in overdose rescue and educated about the New York State GSL were enrolled in a prospective longitudinal study. Trained researchers conducted baseline and 3-, 6-, and 12-month follow-up surveys with study participants to assess participant knowledge of the GSL and responses to witnessed overdoses. At the 12-month follow-up, participants had witnessed 326 overdoses. In the overdose events where the participant had correct knowledge of the GSL at the time of the event, the odds of a bystander calling 911 were over 3 times greater than when the witness had incorrect knowledge of the GSL (odds ratio [OR] = 3.3, 95% confidence interval [CI]: 1.4-7.5). This association remained significant after adjusting for age, gender, race of the witness, and overdose setting (adjusted OR [AOR] = 3.6, 95% CI: 1.4-9.4). This study shows a clear association between knowledge of the GSL and 911-calling behavior. Legislation that protects overdose responders along with public awareness of the law may be an effective strategy to increase rates of 911-calling in response to overdose events and decrease overdose-related mortality.

OBJECTIVES: The purpose of this study was to determine whether breast-feeding has a dose-related protective effect against illness and whether it confers special health benefits to poor infants. METHODS: The association between breast-feeding dose and illnesses in the first 6 months of life was analyzed with generalized estimating equations regression for 7092 infants from the National Maternal and Infant Health Survey. Breast-feeding dose (ratio of breast-feedings to other feedings) was categorized as full, most, equal, less, or no breast-feeding. RESULTS: Compared with no breast-feeding, full breast-feeding infants had lower odds ratios of diarrhea, cough or wheeze, and vomiting and lower mean ratios of illness months and sick baby medical visits. Most breast-feeding infants had lower odds ratios of diarrhea and cough or wheeze, and equal breast-feeding infants had lower odds ratios of cough or wheeze. Full, most, and equal breast-feeding infants without siblings had lower odds ratios of ear infections and certain other illnesses, but those with siblings did not. Less breast-feeding infants had no reduced odds ratios of illness. Findings did not vary by income. CONCLUSIONS: Full breast-feeding was associated with the lowest illness rates. Minimal (less) breast-feeding was not protective. Breast-feeding conferred similar health benefits in all economic groups. PMID:9987460

Workplace smoking cessation (SC) intervention is effective in increasing quit rate but little was known about the factors associated with voluntary SC promotion. Comprehensive smoke-free legislation, including banning smoking in all indoor area of workplaces, has been enforced in Hong Kong. This survey investigated the prevalence of company's compliance with smoke-free legislation and examined the relation between voluntary SC promotion in workplace and employer's knowledge of and attitude towards smoking and SC. Half (50.3%, n  = 292) of a convenience sample of companies completed a self-administered questionnaire on company's voluntary SC promotion in the workplace. Factors investigated included company's characteristics (size, type, and number of smoking employees); employers' knowledge of smoking, second-hand smoke and SC effects on health; perceived responsibility in assisting employees to quit smoking and smoking prohibition in workplace (smoke free policy). Logistic regression yielded adjusted odds ratio (aOR) for voluntary SC promotion. A notable proportion of companies (14.7%) showed non-compliance with the smoke free workplace ordinance and only 10% voluntarily promoted SC. Perceived greater negative impact of smoking on the company (adjusted odds ratio[aOR] 1.94, 95% confidence interval [CI] 1.18-3.20) and better knowledge of smoking (aOR 1.40, 95%CI 1.00-1.94) were associated with voluntary SC promotion. Positive but non-significant associations were observed between perceived responsibility of assisting employees to quit, workplace smoke free policy and voluntary SC promotion. Company characteristics were generally not associated with voluntary SC promotion except white collar companies were less likely to promote SC (aOR 0.26, 95% CI 0.08-0.85). This is the first survey on company's SC promotion in the Chinese population. A notable proportion of companies was not compliant with the smoke-free workplace ordinance. Employers with a higher level of knowledge and perceived impact of smoking on companies and from blue-collar companies were more likely to promote SC in workplace. The findings inform future workplace intervention design and policy. The study was retrospectively registered at ClinicalTrials.gov (NCT02179424) dated 27 June 2014.

Background Physical activity (PA) is an important treatment regimen for diabetes. The purposes of this study were to evaluate people’s knowledge of how exercise influences wellbeing (termed “PA knowledge” or “knowledge of PA” in this paper) and the resulting association with levels of PA in Chinese adults with Type 2 diabetes, and to identify the valuable demographic and lifestyle factors that possibly influence the association between PA knowledge and level of PA. Methods Two hundred and fifty-eight adults with Type 2 diabetes completed an interviewer-administered survey at a diabetes clinic in Hong Kong. Data on demographics, lifestyle factors and diabetes-related medical indicators were obtained. A 20-item questionnaire was developed to measure PA-related knowledge (one point scored for each correct answer; aggregate score up to 20 points). level of PA was measured by the International Physical Activity Questionnaire. Results The proportions of correct answers to each question ranged from 19.4 to 90.7%. Compared with poorly educated participants, those with university education level and above had PA knowledge scores 1.7 points higher (14.3 vs. 12.6, P<0.05). Younger, female, and obese participants were more likely to have lower level of PA (all P<0.05). After adjustment for age, gender, (BMI) and education level, the odds of having a moderate-to-high level of PA was 19% greater with 1 unit increase in PA knowledge score [95% confidence interval (CI): 1.09–1.29; P<0.001], this association was strongest in participants with tertiary education level or above [odds ratio (OR): 1.35; 95% CI: 1.03–1.77; P<0.05]. Conclusions PA knowledge was positively associated with level of PA. Education level significantly influenced the association between PA knowledge and level of PA, leading to the suggestion of vulnerable groups to target for PA improvement in the face of diabetes.

Antenatal anemia is a major public health problem in the UK, yet there is limited high quality evidence for associated poor clinical outcomes. The objectives of this study were to estimate the incidence and clinical outcomes of antenatal anemia in a Scottish population. A retrospective cohort study of 80 422 singleton pregnancies was conducted using data from the Aberdeen Maternal and Neonatal Databank between 1995 and 2012. Antenatal anemia was defined as haemoglobin ≤ 10 g/dl during pregnancy. Incidence was calculated with 95% confidence intervals and compared over time using a chi-squared test for trend. Multivariable logistic regression was used to adjust for confounding variables. Results are presented as adjusted odds ratios with 95% confidence interval. The overall incidence of antenatal anemia was 9.3 cases/100 singleton pregnancies (95% confidence interval 9.1-9.5), decreasing from 16.9/100 to 4.1/100 singleton pregnancies between 1995 and 2012 (p < 0.001). Maternal anemia was associated with antepartum hemorrhage (adjusted odds ratio 1.26, 95% confidence interval 1.17-1.36), postpartum infection (adjusted odds ratio 1.89, 95% confidence interval 1.39-2.57), transfusion (adjusted odds ratio 1.87, 95% confidence interval 1.65-2.13) and stillbirth (adjusted odds ratio 1.42, 95% confidence interval 1.04-1.94), reduced odds of postpartum hemorrhage (adjusted odds ratio 0.92, 95% confidence interval 0.86-0.98) and low birthweight (adjusted odds ratio 0.77, 95% confidence interval 0.69-0.86). No other outcomes were statistically significant. This study shows the incidence of antenatal anemia is decreasing steadily within this Scottish population. However, given that anemia is a readily correctable risk factor for major causes of morbidity and mortality in the UK, further work is required to investigate appropriate preventive measures. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

Little is known about racial/ethnic differences in men's contraceptive knowledge and attitudes. We used multivariable logistic regression to examine racial/ethnic differences in contraceptive knowledge and attitudes among 903 men aged 18-29 in the 2009 National Survey of Reproductive and Contraceptive Knowledge. Black and Hispanic men were less likely than Whites to have heard of most contraceptive methods, including female and male sterilization, and also had lower knowledge about hormonal and long-acting reversible methods. They were less likely to know that pills are ineffective when 2-3 pills are missed [Blacks: adjusted odds ratio (aOR)=0.42; Hispanics: aOR=0.53] and that fertility was not delayed after stopping the pill (Blacks: aOR=0.52; Hispanics: aOR=0.27). Hispanics were less likely to know that nulliparous women can use the intrauterine device (aOR=0.47). Condom knowledge was similar by race/ethnicity, but Blacks were less likely to view condoms as a hassle than Whites (aOR=0.46). Efforts to educate men, especially men of color, about contraceptive methods are needed. Published by Elsevier Inc.

A note on the use of the generalized odds ratio in meta-analysis of association studies involving bi- and tri-allelic polymorphisms.

PubMed

Pereira, Tiago V; Mingroni-Netto, Regina C

The generalized odds ratio (GOR) was recently suggested as a genetic model-free measure for association studies. However, its properties were not extensively investigated. We used Monte Carlo simulations to investigate type-I error rates, power and bias in both effect size and between-study variance estimates of meta-analyses using the GOR as a summary effect, and compared these results to those obtained by usual approaches of model specification. We further applied the GOR in a real meta-analysis of three genome-wide association studies in Alzheimer's disease. For bi-allelic polymorphisms, the GOR performs virtually identical to a standard multiplicative model of analysis (e.g. per-allele odds ratio) for variants acting multiplicatively, but augments slightly the power to detect variants with a dominant mode of action, while reducing the probability to detect recessive variants. Although there were differences among the GOR and usual approaches in terms of bias and type-I error rates, both simulation- and real data-based results provided little indication that these differences will be substantial in practice for meta-analyses involving bi-allelic polymorphisms. However, the use of the GOR may be slightly more powerful for the synthesis of data from tri-allelic variants, particularly when susceptibility alleles are less common in the populations (≤10%). This gain in power may depend on knowledge of the direction of the effects. For the synthesis of data from bi-allelic variants, the GOR may be regarded as a multiplicative-like model of analysis. The use of the GOR may be slightly more powerful in the tri-allelic case, particularly when susceptibility alleles are less common in the populations.

Sleep deprivation can impair attention, mood, and performance; however, few effective sleep education programs are available. The aim of this study was to assess the effect of a sleep education website, Sleep to Stay Awake (sleeptostayawake.org), on sleep behaviors of college students. College students (age 18 years or older) attending a public Midwestern university were randomized to control or intervention groups. All subjects completed baseline surveys that included demographics, Pittsburgh Sleep Quality Index, Patient Health Questionnaire, sleep knowledge, and measures of sleepiness and circadian rhythm. The intervention group then undertook the online intervention. Surveys were repeated at 1 week and at 8 weeks. Students who participated included 295 controls and 254 intervention subjects. The mean age was 21.9 ± 4.1 years and 41.7% were male. Survey results at 8 weeks showed that more intervention subjects reported improved sleep behaviors (50.3% versus 39.5%, P = .04). Intervention subjects were more likely to stop electronics use earlier (odds ratio [95% confidence interval] = 1.5 [1.0-2.4]), keep a more regular sleep schedule (1.6 [1.06-2.4]), have an earlier weekday rise time (2.4 [1.3-4.4]), and have a lower likelihood of insufficient sleep prior to examinations (0.46 [0.28-0.76]). The intervention group had improvement in mean sleep quality (odds ratio = 5.8 versus 6.6, P < .001) and depression scores (odds ratio = 4.6 versus 5.6, P = .03). No significant differences were found in the other measures. A brief and personalized online sleep education intervention improved sleep behaviors, sleep quality, and depressions scores. This novel approach to address sleep deprivation, poor sleep habits, and mood among college students may offer an effective and inexpensive remedy. © 2018 American Academy of Sleep Medicine.

Mucin4 (MUC4) is a secreted glycoprotein. Numerous studies had indicated that MUC4 was an attractive prognostic tumor biomarker. However, the results of different studies have been inconsistent. So we conducted this meta-analysis to explore the association between MUC4 expression and cancer prognosis. A systematically comprehensive search was performed through PubMed, EMBASE and CNKI (Chinese National Knowledge Infrastructure). Prognostic value of MUC4 expression in malignancy patients was evaluated by pooled hazard ratios (HRs) and their 95% confidence intervals (CIs). Meanwhile, pooled odds ratio (OR) with 95% CI was appropriate for the association between MUC4 expression and clinicopathological parameters. Eighteen studies including 1,933 patients were enrolled in this meta-analysis. Significant association was found between elevated MUC4 expression and poorer overall survival (OS) with pooled hazard ratio (HR) of 1.87 [95% confidence interval (CI): 1.58-2.23, P<0.001]. Significant associations were also detected in biliary tract carcinoma (HR: 2.41, 95% CI: 1.69-3.42, P<0.001), pancreatic cancer (HR: 2.01, 95% CI: 1.42-2.86, P<0.001) and colorectal cancer (HR: 1.73, 95% CI: 1.17-2.54, P=0.006). Moreover, combined odds ratio (OR) of MUC4 indicated that MUC4 overexpression was associated with tumor stage, tumor invasion and lymph node metastasis. Our results demonstrated that MUC4 may be exploited as a novel prognostic biomarker for cancer patients.

To describe the association between socio-economic position, health status and quality of diabetes care in people with Type 2 diabetes in France, where people may receive full healthcare coverage for chronic disease. Data from a national cross-sectional survey performed in people pharmacologically treated for diabetes were used. They combined data from medical claims, hospital discharge, questionnaires for patients (n = 3894 with Type 2 diabetes) and their physicians (n = 2485). Socio-economic position was assessed using educational level (low, intermediate, high) and ability to make ends meet (financial difficulties vs. financially comfortable). People with diabetes reporting financial difficulties were more likely to be smokers (adjusted odds ratio 1.4; 95% CI 1.1-1.6) and obese (adjusted odds ratio 1.3; 95% CI 1.2-1.6) and to have poorer glycaemic control (HbA1c > 64 mmol/mol (8%); adjusted odds ratio 1.4; 95% CI 1.1-1.8), than those who were financially comfortable. They were more likely to have their diabetes diagnosed because of complications (adjusted odds ratio 1.6; 95% CI 1.3-2.0). They were also more likely to have coronary and podiatric complications (adjusted odds ratios 1.3; 95% CI 1.1-1.6 and 1.7; 95% CI 1.4-2.2, respectively). They benefited more often from full coverage (adjusted odds ratio 1.3; 95% CI 1.1-1.6), visited general practitioners more often (ratio of estimated marginal means 1.2; 95% CI 1.1-1.2) but specialists less often (adjusted odds ratio 0.7; 95% CI 0.6-0.8 for a visit to private ophthalmologist). They also felt less well informed about their condition. Despite frequent access to full healthcare coverage, socio-economic position has an impact on the diagnosis of diabetes, health status and quality of diabetes care in France. © 2015 The Authors.

The objective of this study was to identify the social factors that explain the differences in knowledge with regards to HIV/AIDS among immigrants in the Basque Country (Spain). We conducted a cross-sectional study based on information obtained in the Basque Health Survey for 754 immigrants from: 86 China, 368 Latin America, 237 the Maghreb and 74 Senegal. Odds ratios (95% CI) were calculated from logistic regression models to measure the degree of association between inadequate knowledge regarding transmission, prevention and places where HIV testing is offered, and the independent variables. We found that this inadequate knowledge is associated with place of birth, sex, a lower level of education, immigration status, difficulties in understanding Spanish, and not receiving advice about AIDS in primary care. These findings indicate that initiatives must be developed to promote equity in the provision of healthcare through clinical guidelines, including details of the specific needs of different groups of immigrants and considering gender issues.

The objective of this study was to identify determinants of human immunodeficiency virus (HIV) knowledge regarding mother-to-child transmission (MTCT) among pregnant women at Tijuana General Hospital, Baja California, Mexico. Between March and November 2003, patients from the prenatal care (n = 1294) and labor and delivery (L&D) units (n = 495) participated in a cross-sectional study to measure HIV knowledge. Less than one-third (30%) knew that HIV could be transmitted to a child during delivery, and 36% knew that HIV could be transmitted by breast-feeding. Only 27% knew that an MTCT could be prevented. Prenatal patients were more likely to know that MTCT was preventable (prenatal: 31% versus L&D 25%; P = .02). Logistic regression indicated that prenatal patients (odds ratio = 1.49, confidence interval 1.07-2.07) were more likely to know that HIV could be transmitted through breast-feeding. Overall, both groups had poor knowledge regarding MTCT of HIV. © The Author(s) 2014.

To evaluate whether text-messaging programs can improve reproductive health among adolescent girls in low- and middle-income countries. We conducted a cluster-randomized controlled trial among 756 female students aged 14 to 24 years in Accra, Ghana, in 2014. We randomized 38 schools to unidirectional intervention (n = 12), interactive intervention (n = 12), and control (n = 14). The unidirectional intervention sent participants text messages with reproductive health information. The interactive intervention engaged adolescents in text-messaging reproductive health quizzes. The primary study outcome was reproductive health knowledge at 3 and 15 months. Additional outcomes included self-reported pregnancy and sexual behavior. Analysis was by intent-to-treat. From baseline to 3 months, the unidirectional intervention increased knowledge by 11 percentage points (95% confidence interval [CI] = 7, 15) and the interactive intervention by 24 percentage points (95% CI = 19, 28), from a control baseline of 26%. Although we found no changes in reproductive health outcomes overall, both unidirectional (odds ratio [OR] = 0.14; 95% CI = 0.03, 0.71) and interactive interventions (OR = 0.15; 95% CI = 0.03, 0.86) lowered odds of self-reported pregnancy for sexually active participants. Text-messaging programs can lead to large improvements in reproductive health knowledge and have the potential to lower pregnancy risk for sexually active adolescent girls.

Leishmaniasis: Who Uses Personal Protection among Military Personnel in Colombia?

PubMed

González, Aida M; Solís-Soto, María Teresa; Radon, Katja

Leishmaniasis is common in Colombia, negatively affecting the health of military personnel active in endemic areas. The disease is transmitted by sand fly bites. Therefore, during duty, use of long-sleeved uniforms and other clothes treated with permethrin and application of mosquito repellent are important personal preventive measures. The objective of this study was to assess personal and occupational factors associated with the use of personal protection in male soldiers deployed to Leishmaniasis-endemic areas. Three hundred soldiers participated in a cross-sectional questionnaire study (response 84.3%). The self-administered questionnaire contained questions about sociodemographics, duration of service, compliance with personal mosquito protection, and knowledge about leishmaniasis. Descriptive analyses were followed by multiple logistic regression models adjusted for potential confounders (EpiInfo Version 7.0) FINDINGS: Overall, 23% of the soldiers reported complete use of the recommended personal protection measures. About 83% of the participants had heard about leishmaniasis. In the adjusted regression model, knowledge about leishmaniasis (adjusted odds ratio = 2.9; 95% confidence interval: 1.1-7.2) and being enrolled in the army for more than 5 years (2.2; 1.1-4.1) increased the odds of using personal protection. Improving knowledge about leishmaniasis is one measure to increase use of personal protection, thereby diminishing the risk of infection. Copyright © 2017 Icahn School of Medicine at Mount Sinai.

The elevated fluoride from drinking water impacts on T 3 , T 4 and TSH hormones. The aim was study impacts of drinking water fluoride on T 3 , T 4 and TSH hormones inYGA (Yazd Greater Area). In this case- control study 198 cases and 213 controls were selected. Fluoride was determined by the SPADNS Colorimetric Method. T 3 , T 4 and TSH hormones tested in the Yazd central laboratory by RIA (Radio Immuno Assay) method. The average amount of TSH and T 3 hormones based on the levels of fluoride in two concentration levels 0-0.29 and 0.3-0.5 (mg/L) was statistically significant (P = 0.001 for controls and P = 0.001 for cases). In multivariate regression logistic analysis, independent variable associated with Hypothyroidism were: gender (odds ratio: 2.5, CI 95%: 1.6-3.9), family history of thyroid disease (odds ratio: 2.7, CI 95%: 1.6-4.6), exercise (odds ratio: 5.34, CI 95%: 3.2-9), Diabetes (odds ratio: 3.7, CI 95%: 1.7-8), Hypertension (odds ratio: 3.2, CI 95%: 1.3-8.2), water consumption (odds ratio: 4, CI 95%: 1.2-14). It was found that fluoride has impacts on TSH, T 3 hormones even in the standard concentration of less than 0.5 mg/L. Application of standard household water purification devices was recommended for hypothyroidism.

For more than three decades, foot and musculoskeletal conditions have been documented among both Asian [Elephas maximus] and African [Loxodonta africana] elephants in zoos. Although environmental factors have been hypothesized to play a contributing role in the development of foot and musculoskeletal pathology, there is a paucity of evidence-based research assessing risk. We investigated the associations between foot and musculoskeletal health conditions with demographic characteristics, space, flooring, exercise, enrichment, and body condition for elephants housed in North American zoos during 2012. Clinical examinations and medical records were used to assess health indicators and provide scores to quantitate conditions. Using multivariable regression models, associations were found between foot health and age [P value = 0.076; Odds Ratio = 1.018], time spent on hard substrates [P value = 0.022; Odds Ratio = 1.014], space experienced during the night [P value = 0.041; Odds Ratio = 1.008], and percent of time spent in indoor/outdoor exhibits during the day [P value < 0.001; Odds Ratio = 1.003]. Similarly, the main risk factors for musculoskeletal disorders included time on hard substrate [P value = 0.002; Odds Ratio = 1.050] and space experienced in indoor/outdoor exhibits [P value = 0.039; Odds Ratio = 1.037]. These results suggest that facility and management changes that decrease time spent on hard substrates will improve elephant welfare through better foot and musculoskeletal health.

Genitourinary infections (GUIs) have been associated with increased risk of gastroschisis in 2 studies. Using data collected in the Slone Epidemiology Center Birth Defects Study, we examined the association between GUI and gastroschisis. From 1998 to 2010, mothers of 249 gastroschisis cases and 7,104 controls were interviewed within 6 months of delivery about pregnancy events, including vaginal infections, genital herpes, urinary tract infections (UTIs), and other sexually transmitted diseases (STDs). Women were considered exposed if they reported at least 1 instance of a GUI in the first trimester. Logistic regression models were used to calculate odds ratios and 95% confidence intervals. Women who reported having any GUI had an adjusted odds ratio of 1.8 (95% confidence interval (CI): 1.3, 2.4). The highest risk was seen among women who reported a UTI only (adjusted odds ratio = 2.3, 95% CI: 1.5, 3.5), while the odds ratio for an STD only was slightly elevated (adjusted odds ratio = 1.2, 95% CI: 1.0, 1.5). Among women under 25 years of age, the odds ratio for UTI only was 2.6 (95% CI: 1.7, 4.0), and among older women it was 1.8 (95% CI: 0.6, 5.9). When we considered the joint association of UTIs and young maternal age, a synergistic effect was observed. The results of this study add further evidence that UTIs may increase the risk of gastroschisis. PMID:25073472

In order to quantify the risk of pancreatic cancer associated with history of any allergy and specific allergies, to investigate differences in the association with risk according to age, gender, smoking status, or body mass index, and to study the influence of age at onset, we pooled data from 10 case-control studies. In total, there were 3,567 cases and 9,145 controls. Study-specific odds ratios and 95% confidence intervals were calculated by using unconditional logistic regression adjusted for age, gender, smoking status, and body mass index. Between-study heterogeneity was assessed by using the Cochran Q statistic. Study-specific odds ratios were pooled by using a random-effects model. The odds ratio for any allergy was 0.79 (95% confidence interval (CI): 0.62, 1.00) with heterogeneity among studies (P < 0.001). Heterogeneity was attributable to one study; with that study excluded, the pooled odds ratio was 0.73 (95% CI: 0.64, 0.84) (Pheterogeneity = 0.23). Hay fever (odds ratio = 0.74, 95% CI: 0.56, 0.96) and allergy to animals (odds ratio = 0.62, 95% CI: 0.41, 0.94) were related to lower risk, while there was no statistically significant association with other allergies or asthma. There were no major differences among subgroups defined by age, gender, smoking status, or body mass index. Older age at onset of allergies was slightly more protective than earlier age.

2006-02-15

Cohort study of subjects with whiplash-associated disorders (WAD). To assess the association between preinjury factors and neck pain intensity within 30 days after a motor vehicle collision. Neck pain is the main symptom in WAD. There are studies of nonspecific musculoskeletal pain suggesting that pain intensity can be modified by psychologic, personal, or social factors, but, to our knowledge, no studies have investigated the association between such factors and neck pain intensity in WAD. The subjects (n = 5970) either filed a claim or were treated for neck pain within 30 days after a collision. Neck pain intensity was measured on the visual analog scale. Fair or poor health before the collision was associated with severe neck pain in females (odds ratio 4.0, 95% confidence interval 1.8-8.9). Other associated factors in females included low education and prior neck pain. Low family income was associated with severe neck pain in males (odds ratio 2.3, 95% confidence interval 1.5-3.4), as was prior headache and being unaware of the head position at the time of collision. The results suggest that neck pain intensity in WAD seems to be influenced by several factors other than characteristics related to the injury event itself.

Although neurofibromatosis type 1 (NF1) may be associated with an incompletely understood vasculopathy, relative odds of stroke in this population is not known. Using the 1998 to 2009 US Nationwide Inpatient Sample, we performed a case-control study matching cases of NF1 to controls without such a diagnosis. We then compared the odds of stroke between the 2 groups. We used multivariable logistic regression to adjust for known or suspected confounders. NF1 was associated with younger mean age at the time of stroke (41 versus 48) and a lower prevalence of stroke risk factors among adult patients. Pediatric patients with NF1, however, were more likely to have hypertension. Patients with NF1 were significantly more likely to be diagnosed with any stroke (odds ratio, 1.2; P<0.0001) than the general population. The odds of intracerebral hemorrhage were greatest among hemorrhagic stroke types analyzed (odds ratio, 1.9; P<0.0001). In the pediatric NF1 population, the odds of intracerebral hemorrhage were more dramatically elevated (odds ratio, 8.1; P<0.0001). The odds of ischemic stroke were also increased with NF1 in the pediatric (odds ratio, 3.4; P<0.0001) but not in the adult population. When compared with the general population, the odds of any type of stroke are significantly increased for patients with NF1, both adult and pediatric. This risk is most notable for hemorrhagic strokes although it is also increased for ischemic strokes in children. Physicians should be aware of the increased risk of stroke in this population, and consider stroke as a potential cause of new neurological symptoms. © 2015 American Heart Association, Inc.

Non-Hodgkin's lymphoma (NHL) has been subject to several epidemiological studies and various occupational and non-occupational exposures have been identified as determinants. The present study is a pooled analysis of two earlier methodologically similar case-referent studies encompassing 199 cases of NHL and 479 referents, all alive. Exposure information, mainly on occupational agents, was obtained by mailed questionnaires to the subjects. Exposure to white spirits, thinner, and aviation gasoline as well as work as a painter was connected with increased odds ratios, whereas no increased risk was noted for benzene. Farming was associated with a decreased odds ratio and exposure to phenoxy herbicides, wood preservatives, and work as a lumberjack showed increased odds ratios. Moreover, exposure to plastic and rubber chemicals and also contact with some kinds of pets appeared with increased odds ratios. Office employment and housework showed decreased odds ratios. This study indicates the importance of investigating exposures not occurring very frequently in the general population. Solvents were studied as a group of compounds but were also separated into various specific compounds. The present findings suggest that the carcinogenic property of solvents is not only related to the aromatic ones or to the occurrence of benzene contamination, but also to other types of compounds.

To explore the relationship between caregivers' nutritional knowledge and children's dietary behavior in rural areas of China. A cross-sectional study was conducted. 3361 rural caregivers and their children, aged 2 to 7 years old, were selected randomly and surveyed by questionnaire. Logistic regression models were used to identify the relationship between caregivers' nutritional knowledge and the children's dietary behaviors. The awareness level of nutritional knowledge among rural caregivers was 57.9%; among the children surveyed, 79.6% did not like to drink milk, 66.0% were considered choosy of food, 84.1% regularly snacked, 24.4% frequently skipped breakfast, and 13.7% did not come to meals on time. Logistic regression models indicated that a caregiver with a low level of nutritional knowledge is a risk factor for a child's unhealth dietary behaviors (snacking excepted): the odds ratios (OR) of not liking to drink milk, being choosy about food, skipping breakfast or not having meals on time are 1.665, 1.338, 1.330 and 1.582, respectively. Caregivers' nutritional knowledge is strongly associated with children's dietary behavior. Nutrition education programs are urgently wanted to improve caregiver's knowledge and thus to improve children's dietary behavior in rural areas of China.

Initiatives aimed at behaviour change of key populations such as the female sex workers (FSWs) are pivotal in reducing the transmission of HIV. An 8-year implementation research to establish the predictor factors of behaviour change among FSWs in Kenya was initiated by the African Medical Research Foundation (AMREF) with Sida and DfID support. This cross-sectional survey interviewed 159 female sex workers (FSWs) identified through snowball procedure. The measurement of behaviour change was based on: the consistent use of condoms with both regular and non regular clients, reduced number of clients, routine checks for STIs, and involvement in alternative income generating activities. The adjusted odds ratios at 95% confidence interval computed during binary logistic regression analysis were used to determine the behaviour change predictor factors. Most FSWs (84%) had participated in AMREF's integrated intervention programme for at least one year and 59.1% had gone through behaviour change. The adjusted odds ratio showed that the FSWs with secondary education were 2.23 times likely to change behaviour, protestants were 4.61 times, those in sex work for >4 years were 2.36 times, FSWs with good HIV prevention knowledge were 4.37 times, and those engaged in alternative income generating activities were 2.30 times more likely to change their behaviour compared to respective counterparts. Behaviour change among FSWs was possible and is associated with the level of education, religious affiliation, number of years in sex work and one's level of HIV prevention knowledge. A re-orientation on the peer education programme to focus on HIV preventive measures beyond use of condoms is emphasized.

Purpose To evaluate knowledge of interventional radiologists (IRs) and vascular surgeons (VSs) on the cost of common devices and procedures and to determine factors associated with differences in understanding. Materials and Methods An online survey was administered to US faculty IRs and VSs. Demographic information and physicians’ opinions on hospital costs were elicited. Respondents were asked to estimate the average price of 15 commonly used devices and to estimate the work relative value units (wRVUs) and average Medicare reimbursements for 10 procedures. Answer estimates were deemed correct if values were ± 25% of the actual costs. Multivariate logistical regression was used to calculate odds ratios and 95% confidence intervals. Results Of the 4,926 participants contacted, 1,090 (22.1%) completed the questionnaire. Overall, 19.8%, 22.8%, and 31.9% were accurate in price estimations of devices, Medicare reimbursement, and wRVUs for procedures. Physicians who thought themselves adequately educated about wRVUs were more accurate in predicting procedural costs in wRVUs than physicians who responded otherwise (odds ratio = 1.40, 95% confidence interval, 1.29–1.52; P < .0001). Estimation accuracies for procedures showed a positive trend in more experienced physicians (≥ 16 y), private practice physicians, and physicians who practice in rural areas. Conclusions This study suggests that IRs and VSs have limited knowledge regarding device costs. Given the current health care environment, more attention should be placed on cost education and awareness so that physicians can provide the most cost-effective care. PMID:26706189

Poor health knowledge and behaviour is a risk for the spread of antibiotic resistance: survey of higher secondary school students in Goa, India.

We assessed antibiotic knowledge and practice among youth in India, where antibiotics are widely available without prescription. Randomly selected school questionnaire survey representing four regions in Goa, India, with students ( n = 773) aged 16-17. Most students (67%) were unaware of the problem of antibiotic resistance, with around half (49%) mistakenly thinking that bacteria cause cold or flu. Around one-fifth (19%) said they frequently self-medicate with antibiotics, 57% would discontinue antibiotics when symptoms alleviated and 24% stored unused antibiotics at home. Generalised linear mixed models (GLMM) showed that females consistently had poorer antibiotic knowledge than males. Especially notable were the higher odds in females for reporting incorrectly that antibiotics kill harmful viruses (odds ratio (OR) = 1.93; 99.5% confidence interval (CI) = 1.09-3.41) and for reporting incorrectly that antibiotics do not kill harmless bacteria (OR = 2.02; 99.5% CI = 1.16-3.51). Poor antibiotic practice was not clearly differentiated between males and females. In terms of poor antibiotic practice, one model showed notable results for educational stream: both arts and commerce students were more likely than science students to say they would discontinue antibiotics when symptoms alleviated and before the antibiotic course of treatment was finished (arts: OR = 2.76; 99.5% CI = 1.58-4.82 and commerce: OR = 1.79; 99.5% CI = 1.06-3.04). Young adults in India had poor antibiotic knowledge and practice. Efforts to improve antibiotic health knowledge and safe practice are required to help prevent the spread of antibiotic resistance.

Evidence suggests Latinas residing along the United States-Mexico border face higher breast cancer mortality rates compared to Latinas in the interior of either country. The purpose of this study was to investigate breast cancer knowledge, attitudes, and use of breast cancer preventive screening among U.S. Latina and Mexican women residing along the U.S.-Mexico border. For this binational cross-sectional study, 265 participants completed an interviewer-administered questionnaire that obtained information on sociodemographic characteristics, knowledge, attitudes, family history, and screening practices. Differences between Mexican (n=128) and U.S. Latina (n=137) participants were assessed by Pearson's chi-square, Fischer's exact test, t tests, and multivariate regression analyses. U.S. Latinas had significantly increased odds of having ever received a mammogram/breast ultrasound (adjusted odds ratio [OR]=2.95) and clinical breast examination (OR=2.67) compared to Mexican participants. A significantly greater proportion of Mexican women had high knowledge levels (54.8%) compared to U.S. Latinas (45.2%, p<0.05). Age, education, and insurance status were significantly associated with breast cancer screening use. Despite having higher levels of breast cancer knowledge than U.S. Latinas, Mexican women along the U.S.-Mexico border are not receiving the recommended breast cancer screening procedures. Although U.S. border Latinas had higher breast cancer screening levels than their Mexican counterparts, these levels are lower than those seen among the general U.S. Latina population. Our findings underscore the lack of access to breast cancer prevention screening services and emphasize the need to ensure that existing breast cancer screening programs are effective in reaching women along the U.S.-Mexico border.

Nonadherence to colorectal cancer (CRC) screening among Asian Americans is high but not well understood. This study examined correlates of screening intention among Filipino, Hmong, and Korean Americans who were nonadherent to CRC screening. Using cross-sectional, preintervention survey data from 504 Asian Americans (115 Filipinos, 185 Hmong, and 204 Koreans) aged 50-75 years who were enrolled in a multisite cluster randomized controlled trial of lay health educator intervention, we analyzed correlates of self-reported CRC screening nonadherence, which was defined as not being up-to-date for fecal occult blood test, sigmoidoscopy, or colonoscopy. Only 26.8% of participants indicated intention to obtain screening within 6 months (Hmong: 12.4%; Korean: 30.8%; and Filipino: 42.6%; P < .001). Only one third of participants had undergone a prior screening, and a majority did not know that screening is a method of CRC prevention method (61.3%) or had any knowledge of CRC screening guidelines (53.4%). Multivariable analyses revealed that patient-provider ethnicity concordance, provider's recommendation of screening, participants' prior CRC screening, perceived severity and susceptibility of CRC, and knowledge of guidelines were positively associated with screening intention. Specifically, knowing one or more screening guidelines doubled the odds of screening intention (adjusted odds ratio, 2.38; 95% confidence interval, 1.32-4.28). Hmong were less likely to have screening intention than Filipinos, which was unexplained by socio-demographics, health care factors, perceived needs for CRC screening, or knowledge of screening guidelines. CRC screening intention among nonadherent Filipino, Hmong, and Korean Americans was low. Targeting knowledge of CRC screening guidelines may be effective strategies for increasing CRC screening intention among nonadherent Asian Americans.

Objectives This study examines in a cross-sectional study ‘the tobacco control environment’ including tobacco policy implementation and its association with quit ratio. Setting 545 communities from 17 high-income, upper-middle, low-middle and low-income countries (HIC, UMIC, LMIC, LIC) involved in the Environmental Profile of a Community's Health (EPOCH) study from 2009 to 2014. Participants Community audits and surveys of adults (35–70 years, n=12 953). Primary and secondary outcome measures Summary scores of tobacco policy implementation (cost and availability of cigarettes, tobacco advertising, antismoking signage), social unacceptability and knowledge were associated with quit ratios (former vs ever smokers) using multilevel logistic regression models. Results Average tobacco control policy score was greater in communities from HIC. Overall 56.1% (306/545) of communities had >2 outlets selling cigarettes and in 28.6% (154/539) there was access to cheap cigarettes (<5cents/cigarette) (3.2% (3/93) in HIC, 0% UMIC, 52.6% (90/171) LMIC and 40.4% (61/151) in LIC). Effective bans (no tobacco advertisements) were in 63.0% (341/541) of communities (81.7% HIC, 52.8% UMIC, 65.1% LMIC and 57.6% LIC). In 70.4% (379/538) of communities, >80% of participants disapproved youth smoking (95.7% HIC, 57.6% UMIC, 76.3% LMIC and 58.9% LIC). The average knowledge score was >80% in 48.4% of communities (94.6% HIC, 53.6% UMIC, 31.8% LMIC and 35.1% LIC). Summary scores of policy implementation, social unacceptability and knowledge were positively and significantly associated with quit ratio and the associations varied by gender, for example, communities in the highest quintile of the combined scores had 5.0 times the quit ratio in men (Odds ratio (OR) 5·0, 95% CI 3.4 to 7.4) and 4.1 times the quit ratio in women (OR 4.1, 95% CI 2.4 to 7.1). Conclusions This study suggests that more focus is needed on ensuring the tobacco control policy is actually implemented, particularly in LMICs. The gender-related differences in associations of policy, social unacceptability and knowledge suggest that different strategies to promoting quitting may need to be implemented in men compared to women.

Obesity during pregnancy is associated with a number of adverse obstetric outcomes that include gestational diabetes mellitus, macrosomia, and preeclampsia. Increasing evidence shows that bariatric surgery may decrease the risk of these outcomes. Our aim was to evaluate the benefits and risks of bariatric surgery in obese women according to obstetric outcomes. We performed a systematic literature search using MEDLINE, Embase, Cochrane, Web of Science, and PubMed from inception up to December 12, 2016. Studies were included if they evaluated patients who underwent bariatric surgery, reported subsequent pregnancy outcomes, and compared these outcomes with a control group. Two reviewers extracted study outcomes independently, and risk of bias was assessed with the use of the Newcastle-Ottawa Quality Assessment Scale. Pooled odds ratios for each outcome were estimated with the Dersimonian and Laird random effects model. After a review of 2616 abstracts, 20 cohort studies and approximately 2.8 million subjects (8364 of whom had bariatric surgery) were included in the metaanalysis. In our primary analysis, patients who underwent bariatric surgery showed reduced rates of gestational diabetes mellitus (odds ratio, 0.20; 95% confidence interval, 0.11-0.37, number needed to benefit, 5), large-for-gestational-age infants (odds ratio, 0.31; 95% confidence interval, 0.17-0.59; number needed to benefit, 6), gestational hypertension (odds ratio, 0.38; 95% confidence interval, 0.19-0.76; number needed to benefit, 11), all hypertensive disorders (odds ratio, 0.38; 95% confidence interval, 0.27-0.53; number needed to benefit, 8), postpartum hemorrhage (odds ratio, 0.32; 95% confidence interval, 0.08-1.37; number needed to benefit, 21), and caesarean delivery rates (odds ratio, 0.50; 95% confidence interval, 0.38-0.67; number needed to benefit, 9); however, group of patients showed an increase in small-for-gestational-age infants (odds ratio, 2.16; 95% confidence interval, 1.34-3.48; number needed to harm, 21), intrauterine growth restriction (odds ratio, 2.16; 95% confidence interval, 1.34-3.48; number needed to harm, 66), and preterm deliveries (odds ratio, 1.35; 95% confidence interval, 1.02-1.79; number needed to harm, 35) when compared with control subjects who were matched for presurgery body mass index. There were no differences in rates of preeclampsia, neonatal intensive care unit admissions, stillbirths, malformations, and neonatal death. Malabsorptive surgeries resulted in a greater increase in small-for-gestational-age infants (P=.0466) and a greater decrease in large-for-gestational-age infants (P=<.0001) compared with restrictive surgeries. There were no differences in outcomes when we used administrative databases vs clinical charts. Although bariatric surgery is associated with a reduction in the risk of several adverse obstetric outcomes, there is a potential for an increased risk of other important outcomes that should be considered when bariatric surgery is discussed with reproductive-age women.

The impact of anesthetic choice on postoperative mortality and morbidity has not been determined with certainty. The authors evaluated the effect of type of anesthesia on postoperative mortality and morbidity in a retrospective cohort study of consecutive hip fracture patients, aged 60 yr or older, who underwent surgical repair at 20 US hospitals between 1983 and 1993. The primary outcome was defined as death within 30 days of the operative procedure. The secondary outcomes were postoperative 7-day mortality, postoperative myocardial infarction, postoperative pneumonia, postoperative congestive heart failure, and postoperative change in mental status. Numerous comorbid conditions were controlled for individually and by several comorbidity indices using logistic regression. General anesthesia was used in 6,206 patients (65.8%) and regional anesthesia in 3,219 patients (3,078 spinal anesthesia and 141 epidural anesthesia). The 30-day mortality rate in the general anesthesia group was 4.4%, compared with 5.4% in the regional anesthesia group (unadjusted odds ratio = 0.80; 95% confidence interval = 0.66-0.97). However, the adjusted odds ratio for general anesthesia increased to 1.08 (0.84-1.38). The adjusted odds ratios for general anesthesia versus regional anesthesia for the 7-day mortality was 0.90 (0.59-1.39) and for postoperative morbidity outcomes were as follows: myocardial infarction: adjusted odds ratio = 1.17 (0.80-1.70); congestive heart failure: adjusted odds ratio = 1.04 (0.80-1.36); pneumonia: adjusted odds ratio = 1.21 (0.87-1.68); postoperative change in mental status: adjusted odds ratio = 1.08 (0.95-1.22). The authors were unable to demonstrate that regional anesthesia was associated with better outcome than was general anesthesia in this large observational study of elderly patients with hip fracture. These results suggest that the type of anesthesia used should depend on factors other than any associated risks of mortality or morbidity.

Antecedents of accompanying impairments in cerebral palsy and their relation to neuroimaging patterns need to be explored. A population-based study of 309 children with cerebral palsy born at term between 1983 and 1994. Prepartum, intrapartum, and postpartum variables previously studied as antecedents of cerebral palsy type and motor severity were analyzed in children with cerebral palsy and cognitive impairment and/or epilepsy, and in children with cerebral palsy without these accompanying impairments. Neuroimaging patterns and their relation to identified antecedents were analyzed. Data were retrieved from the cerebral palsy register of western Sweden, and from obstetric and neonatal records. Children with cerebral palsy and accompanying impairments more often had low birthweight (kg) (odds ratio 0.5, 95% confidence interval 0.3-0.8), brain maldevelopment known at birth (p = 0.007, odds ratio ∞) and neonatal infection (odds ratio 5.4, 95% confidence interval 1.04-28.4). Moreover, neuroimaging patterns of maldevelopment (odds ratio 7.2, 95% confidence interval 2.9-17.2), cortical/subcortical lesions (odds ratio 5.3, 95% confidence interval 2.3-12.2) and basal ganglia lesions (odds ratio 7.6, 95% confidence interval 1.4-41.3) were more common, wheras white matter injury was found significantly less often (odds ratio 0.2, 95% confidence interval 0.1-0.5). In most children with maldevelopment, the intrapartum and postpartum periods were uneventful (p < 0.05). Cerebral maldevelopment was associated with prepartum antecedents, whereas subcortical/cortical and basal ganglia lesions were associated with intrapartum and postpartum antecedents. No additional factor other than those related to motor impairment was associated with epilepsy and cognitive impairment in cerebral palsy. Timing of antecedents deemed important for the development of cerebral palsy with accompanying impairments were supported by neuroimaging patterns. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Odds ratio, risk ratio, and prevalence ratio are some of the measures of association which are often reported in research studies quantifying the relationship between an independent variable and the outcome of interest. There has been much debate on the issue of which measure is appropriate to report depending on the study design. However, the literature on selecting a particular category of the outcome to be modeled and/or change in reference group for categorical independent variables and the effect on statistical significance, although known, is scantly discussed nor published with examples. In this article, we provide an example of a cross-sectional study wherein prevalence ratio was chosen over (Prevalence) odds ratio and demonstrate the analytic implications of the choice of category to be modeled and choice of reference level for independent variables.

Has Their Son Been Vaccinated? Beliefs About Other Parents Matter for Human Papillomavirus Vaccine.

PubMed

Schuler, Christine L; Coyne-Beasley, Tamera

2016-07-01

The goal of this study was to determine if parents' beliefs about social norms of human papillomavirus (HPV) vaccination for sons were associated with knowledge of HPV, intention to vaccinate sons, or beliefs about side effects. A cross-sectional, survey-based study of parents with sons was performed in 2010. Fisher's exact tests were used to examine associations between demographics and responses about social norms. Multivariate logistic regression models examined beliefs about social norms of male HPV vaccination and primary outcomes. Few parents agreed that others were vaccinating sons (n = 31/267, 12%), including 1% responding strongly agree and 11% responding agree. Most parents, 52%, disagreed that others were vaccinating (40% disagree, 11% strongly disagree), and 37% chose prefer not to answer regarding others' vaccination practices. Hispanic parents and those with a high school education or less were significantly more likely to choose prefer not to answer than their respective counterparts regarding vaccination norms. In multivariate models, parents agreeing others were vaccinating sons had greater odds of having high knowledge of HPV (adjusted odds ratio [aOR] high vs low knowledge 3.15, 95% confidence interval [CI] 1.13, 8.77) and increased intention to vaccinate sons (n = 243, aOR = 4.41, 95% CI = 1.51, 12.89). Beliefs about side effects were not significantly associated with beliefs about social norms. Parents' beliefs about others' vaccination practices are important with regard to knowledge of HPV and intention to vaccinate sons. Studying how various public messages about HPV vaccine may influence normative beliefs could be relevant to improving vaccination coverage. © The Author(s) 2015.

Pregnancy and birth outcomes in couples with infertility with and without assisted reproductive technology: with an emphasis on US population-based studies.

PubMed

Luke, Barbara

2017-09-01

Infertility, defined as the inability to conceive within 1 year of unprotected intercourse, affects an estimated 80 million individuals worldwide, or 10-15% of couples of reproductive age. Assisted reproductive technology includes all infertility treatments to achieve conception; in vitro fertilization is the process by which an oocyte is fertilized by semen outside the body; non-in vitro fertilization assisted reproductive technology treatments include ovulation induction, artificial insemination, and intrauterine insemination. Use of assisted reproductive technology has risen steadily in the United States during the past 2 decades due to several reasons, including childbearing at older maternal ages and increasing insurance coverage. The number of in vitro fertilization cycles in the United States has nearly doubled from 2000 through 2013 and currently 1.7% of all live births in the United States are the result of this technology. Since the birth of the first child from in vitro fertilization >35 years ago, >5 million babies have been born from in vitro fertilization, half within the past 6 years. It is estimated that 1% of singletons, 19% of twins, and 25% of triplet or higher multiples are due to in vitro fertilization, and 4%, 21%, and 52%, respectively, are due to non-in vitro fertilization assisted reproductive technology. Higher plurality at birth results in a >10-fold increase in the risks for prematurity and low birthweight in twins vs singletons (adjusted odds ratio, 11.84; 95% confidence interval, 10.56-13.27 and adjusted odds ratio, 10.68; 95% confidence interval, 9.45-12.08, respectively). The use of donor oocytes is associated with increased risks for pregnancy-induced hypertension (adjusted odds ratio, 1.43; 95% confidence interval, 1.14-1.78) and prematurity (adjusted odds ratio, 1.43; 95% confidence interval, 1.11-1.83). The use of thawed embryos is associated with higher risks for pregnancy-induced hypertension (adjusted odds ratio, 1.30; 95% confidence interval, 1.08-1.57) and large-for-gestation birthweight (adjusted odds ratio, 1.74; 95% confidence interval, 1.45-2.08). Among singletons, in vitro fertilization is associated with increased risk of severe maternal morbidity compared with fertile deliveries (vaginal: adjusted odds ratio, 2.27; 95% confidence interval, 1.78-2.88; cesarean: adjusted odds ratio, 1.67; 95% confidence interval, 1.40-1.98, respectively) and subfertile deliveries (vaginal: adjusted odds ratio, 1.97; 95% confidence interval, 1.30-3.00; cesarean: adjusted odds ratio, 1.75; 95% confidence interval, 1.30-2.35, respectively). Among twins, cesarean in vitro fertilization deliveries have significantly greater severe maternal morbidity compared to cesarean fertile deliveries (adjusted odds ratio, 1.48; 95% confidence interval, 1.14-1.93). Subfertility, with or without in vitro fertilization or non-in vitro fertilization infertility treatments to achieve a pregnancy, is associated with increased risks of adverse maternal and perinatal outcomes. The major risk from in vitro fertilization treatments of multiple births (and the associated excess of perinatal morbidity) has been reduced over time, with fewer and better-quality embryos being transferred.

Meta-analysis of Odds Ratios: Current Good Practices

PubMed Central

Chang, Bei-Hung; Hoaglin, David C.

2016-01-01

Background Many systematic reviews of randomized clinical trials lead to meta-analyses of odds ratios. The customary methods of estimating an overall odds ratio involve weighted averages of the individual trials’ estimates of the logarithm of the odds ratio. That approach, however, has several shortcomings, arising from assumptions and approximations, that render the results unreliable. Although the problems have been documented in the literature for many years, the conventional methods persist in software and applications. A well-developed alternative approach avoids the approximations by working directly with the numbers of subjects and events in the arms of the individual trials. Objective We aim to raise awareness of methods that avoid the conventional approximations, can be applied with widely available software, and produce more-reliable results. Methods We summarize the fixed-effect and random-effects approaches to meta-analysis; describe conventional, approximate methods and alternative methods; apply the methods in a meta-analysis of 19 randomized trials of endoscopic sclerotherapy in patients with cirrhosis and esophagogastric varices; and compare the results. We demonstrate the use of SAS, Stata, and R software for the analysis. Results In the example, point estimates and confidence intervals for the overall log-odds-ratio differ between the conventional and alternative methods, in ways that can affect inferences. Programming is straightforward in the three software packages; an appendix gives the details. Conclusions The modest additional programming required should not be an obstacle to adoption of the alternative methods. Because their results are unreliable, use of the conventional methods for meta-analysis of odds ratios should be discontinued. PMID:28169977

To identify factors associated with prehospital delay in people who have had an acute coronary syndrome. Using a survey we studied patients admitted due to acute coronary syndrome in the 33 Andalusian public hospitals, obtaining information about different types of variables: socio-demographic, contextual,clinical, perception, action, and transportation.Multivariate logistic regression models were applied to calculate the odds ratios for the delay. Of the 1,416 patients studied, more than half had a delay of more than an hour. This is associated to distance to the hospital and means of transport: when the event occurs in the same city,using the patient's own means of transport increases the delay, odds ratio = 1.51 (1.02 to 2.23); if the distance is 1 to 25 kilometers from the hospital,there is no difference between the patient's own means of transport and an ambulance, odds ratio =1.41 and odds ratio =1.43 respectively; and when the distance exceeds 25 kilometers transport by ambulance means more delay, odds ratio = 3.13 and odds ratio = 2.20 respectively. Also, typical symptoms reduce delay amongst men but increase amongst women. Also, not caring and waiting for the resolution of symptoms, seeking health care other than a hospital or emergency services, previous clinical history, being away from home, and having an income under 1,500 euros, all increase delay. Respiratory symptoms reduce delay. Prehospital delay times do not meet health recommendations. The physical and social environment,in addition to clinical, perceptual and attitudinal factors, are associated with this delay.

Neurological diseases are important co-morbidities found in association with bullous pemphigoid. Various neurological conditions (stroke, Parkinson's disease, dementia, epilepsy and multiple sclerosis) have been reported as associations of this bullous disease; whether these are significant has not been definitely proved. However, the presence of neurological conditions is a predictor of poorer prognosis. Our aim was to examine the association of bullous pemphigoid and neurological diseases in Iranian bullous pemphigoid patients. The medical records of one hundred and sixty consecutive bullous pemphigoid patients who presented to the Autoimmune Bullous Diseases Research Center, Tehran, Iran, from 2006 to 2011 were examined for evidence of any neurological disease. The control group comprised of 317 age- and sex-matched subjects. Neurological diseases were seen in 42 (26.4%) patients with bullous pemphigoid and in 29 (9.1%) controls (odds ratio: 3.53 (2.1-5.9), P< 0.001). Comparing cases to controls, stroke was seen in 17.5% versus 4.1%, odds ratio 4.96 (2.49-9.88); dementia in 5.6% versus 1.9%, odds ratio 3.09 (1.08-8.84); Parkinson's disease in 2.5% versus 2.2%, odds ratio 1.14 (0.33-3.94); epilepsy in 2.5% versus 0.6%, odds ratio 4.04 (0.73-22.3); and multiple sclerosis in 0 versus 0.3% odds ratio 1.00 (0.98-1.01). The main limitations of our study were referral bias, retrospective design and a rather low sample size. Neurological diseases in general, and stroke and dementia in particular, were significantly associated with bullous pemphigoid in our study.

Caste- and ethnicity-based inequalities are major obstacles to achieving health equity. The authors investigated whether there is any association between caste- and ethnicity-based inequalities and HIV-related knowledge within caste and ethnic populations. They used the 2011 Nepal Demographic and Health Survey, a nationally represented cross-sectional study data set. The study sample consisted of 11,273 women between 15 and 49 years of age. Univariate and logistic regression models were used to examine the relationship between caste- and ethnicity-based inequalities and HIV-related knowledge. The study sample was divided into high Hindu caste (47.9 percent), "untouchable" caste (18.4 percent), and indigenous populations (33.7 percent). Within the study sample, the high-caste population was found to have the greatest knowledge of the means by which HIV is prevented and transmitted. After controlling for socioeconomic and demographic characteristics, untouchables were the least knowledgeable. The odds ratio for incomplete knowledge about transmission among indigenous populations was 1.27 times higher than that for high Hindu castes, but there was no significant difference in knowledge of preventive measures. The findings suggest the existence of a prevailing HIV knowledge gap. This in turn suggests that appropriate steps need to be implemented to convey complete knowledge to underprivileged populations.

Pay for performance (P4P) is a mechanism by which purchasers of health care offer greater financial rewards to physicians for improving processes or outcomes of care. To our knowledge, P4P has not been studied within the context of a pediatric accountable care organization (ACO). To determine whether P4P promotes pediatric performance improvement in primary care physicians. This retrospective cohort study was conducted from January 1, 2010, to December 31, 2013. A differences-in-differences design was used to test whether P4P improved physician performance in an ACO serving Medicaid children. Data were obtained from 2966 physicians and 323,812 patients. Three groups of physicians were identified: (1) community physicians who received the P4P incentives, (2) nonincentivized community physicians, and (3) nonincentivized physicians employed at a hospital. Pay for performance. Healthcare Effectiveness Data Information Set measure rates for preventive care, chronic care, and acute care primary care services. We examined 21 quality measures, 14 of which were subject to P4P incentives. There were 203 incentivized physicians, 2590 nonincentivized physicians, and 173 nonincentivized hospital physicians. Among them, the incentivized community physicians had greater improvements in performance than the nonincentivized community physicians on 2 of 2 well visits (largest difference was for adolescent well care: odds ratio, 1.05; 99.88% CI, 1.02-1.08), 3 of 10 immunization-incentivized measures (largest difference was for inactivated polio vaccine: odds ratio, 1.14; 99.88% CI, 1.07-1.21), and 2 nonincentivized measures (largest difference was for rotavirus: odds ratio, 1.11; 99.88% CI, 1.04-1.18). The employed physician group at the hospital had greater improvements in performance than the incentivized community physicians on 8 of 14 incentivized measures and 1 of 7 nonincentivized measures (largest difference was for hepatitis A vaccine: odds ratio, 0.34; 99.88% CI, 0.31-0.37). Pay for performance resulted in modest changes in physician performance in a pediatric ACO, but other interventions at the disposal of the ACO may have been even more effective. Further research is required to find methods to enhance quality improvements across large distributed pediatric health systems.

The risk of toxic retinopathy in patients on long-term hydroxychloroquine therapy.

Hydroxychloroquine sulfate is widely used for the long-term treatment of autoimmune conditions but can cause irreversible toxic retinopathy. Prior estimations of risk were low but were based largely on short-term users or severe retinal toxicity (bull's eye maculopathy). The risk may be much higher because retinopathy can be detected earlier when using more sensitive screening techniques. To reassess the prevalence of and risk factors for hydroxychloroquine retinal toxicity and to determine dosage levels that facilitate safe use of the drug. Retrospective case-control study in an integrated health organization of approximately 3.4 million members among 2361 patients who had used hydroxychloroquine continuously for at least 5 years according to pharmacy records and who were evaluated with visual field testing or spectral-domain optical coherence tomography. Hydroxychloroquine use for at least 5 years. Retinal toxicity as determined by characteristic visual field loss or retinal thinning and photoreceptor damage, as well as statistical measures of risk factors and prevalence. Real body weight predicted risk better than ideal body weight and was used for all calculations. The overall prevalence of hydroxychloroquine retinopathy was 7.5% but varied with daily consumption (odds ratio, 5.67; 95% CI, 4.14-7.79 for >5.0 mg/kg) and with duration of use (odds ratio, 3.22; 95% CI, 2.20-4.70 for >10 years). For daily consumption of 4.0 to 5.0 mg/kg, the prevalence of retinal toxicity remained less than 2% within the first 10 years of use but rose to almost 20% after 20 years of use. Other major risk factors include kidney disease (odds ratio, 2.08; 95% CI, 1.44-3.01) and concurrent tamoxifen citrate therapy (odds ratio, 4.59; 95% CI, 2.05-10.27). These data suggest that hydroxychloroquine retinopathy is more common than previously recognized, especially at high dosages and long duration of use. While no completely safe dosage is identified from this study, daily consumption of 5.0 mg/kg of real body weight or less is associated with a low risk for up to 10 years. Knowledge of these data and risk factors should help physicians prescribe hydroxychloroquine in a manner that will minimize the likelihood of vision loss.

The number of multidrug-resistant tuberculosis patients is increasing each year in many countries all around the globe. Malaysia has no exception in facing this burdensome health problem. We aimed to investigate the factors that contribute to the occurrence of multidrug-resistant tuberculosis among Malaysian tuberculosis patients. An unmatched case-control study was conducted among tuberculosis patients who received antituberculosis treatments from April 2013 until April 2014. Cases are those diagnosed as pulmonary tuberculosis patients clinically, radiologically, and/or bacteriologically, and who were confirmed to be resistant to both isoniazid and rifampicin through drug-sensitivity testing. On the other hand, pulmonary tuberculosis patients who were sensitive to all first-line antituberculosis drugs and were treated during the same time period served as controls. A total of 150 tuberculosis patients were studied, of which the susceptible cases were 120. Factors found to be significantly associated with the occurrence of multidrug-resistant tuberculosis are being Indian or Chinese (odds ratio 3.17, 95% confidence interval 1.04-9.68; and odds ratio 6.23, 95% confidence interval 2.24-17.35, respectively), unmarried (odds ratio 2.58, 95% confidence interval 1.09-6.09), living in suburban areas (odds ratio 2.58, 95% confidence interval 1.08-6.19), are noncompliant (odds ratio 4.50, 95% confidence interval 1.71-11.82), were treated previously (odds ratio 8.91, 95% confidence interval 3.66-21.67), and showed positive sputum smears at the 2nd (odds ratio 7.00, 95% confidence interval 2.46-19.89) and 6th months of treatment (odds ratio 17.96, 95% confidence interval 3.51-91.99). Living in suburban areas, positive sputum smears in the 2nd month of treatment, and was treated previously are factors that independently contribute to the occurrence of multidrug-resistant tuberculosis. Those with positive smears in the second month of treatment, have a history of previous treatment, and live in suburban areas are found to have a higher probability of becoming multidrug resistant. The results presented here may facilitate improvements in the screening and detection process of drug-resistant patients in Malaysia in the future.

Increasing availability of individual genomic information suggests that patients will need knowledge about genome sequencing to make informed decisions, but prior research is limited. In this study, we examined genome sequencing knowledge before and after informed consent among 311 participants enrolled in the ClinSeq™ sequencing study. An exploratory factor analysis of knowledge items yielded two factors (sequencing limitations knowledge; sequencing benefits knowledge). In multivariable analysis, high pre-consent sequencing limitations knowledge scores were significantly related to education [odds ratio (OR): 8.7, 95% confidence interval (CI): 2.45-31.10 for post-graduate education, and OR: 3.9; 95% CI: 1.05, 14.61 for college degree compared with less than college degree] and race/ethnicity (OR: 2.4, 95% CI: 1.09, 5.38 for non-Hispanic Whites compared with other racial/ethnic groups). Mean values increased significantly between pre- and post-consent for the sequencing limitations knowledge subscale (6.9-7.7, p < 0.0001) and sequencing benefits knowledge subscale (7.0-7.5, p < 0.0001); increase in knowledge did not differ by sociodemographic characteristics. This study highlights gaps in genome sequencing knowledge and underscores the need to target educational efforts toward participants with less education or from minority racial/ethnic groups. The informed consent process improved genome sequencing knowledge. Future studies could examine how genome sequencing knowledge influences informed decision making. © 2012 John Wiley & Sons A/S.

To investigate and analyse the existing evidence supporting statin therapy in patients with lower limb atherosclerotic arterial disease. A systematic search of electronic information sources was undertaken to identify studies comparing cardiovascular outcomes in patients with lower limb peripheral arterial disease treated with a statin and those not receiving a statin. Estimates were combined applying fixed- or random-effects models. Twelve observational cohort studies and two randomised trials reporting 19,368 patients were selected. Statin therapy was associated with reduced all-cause mortality (odds ratio 0.60, 95% confidence interval 0.46-0.78) and incidence of stroke (odds ratio 0.77, 95% confidence interval 0.67-0.89). A trend towards improved cardiovascular mortality (odds ratio 0.62, 95% confidence interval 0.35-1.11), myocardial infarction (odds ratio 0.62, 95% confidence interval 0.38-1.01), and the composite of death/myocardial infarction/stroke (odds ratio 0.91, 95% confidence interval 0.81-1.03), was identified. Meta-analyses of studies performing adjustments showed decreased all-cause mortality in statin users (hazard ratio 0.77, 95% confidence interval 0.68-0.86). Evidence supporting statins' protective role in patients with lower limb peripheral arterial disease is insufficient. Statin therapy seems to be effective in reducing all-cause mortality and the incidence cerebrovascular events in patients diagnosed with peripheral arterial disease. Copyright © 2014 Elsevier Inc.

Farmers engage in activities that result in exposure to diesel exhaust, solvents, welding fumes, and other respiratory irritants. Using the Agricultural Health Study, a cohort of pesticide applicators in Iowa and North Carolina, we evaluated the odds of wheeze associated with nonpesticide occupational exposures. We used logistic regression models controlling for age, state, smoking, and history of asthma or atopy to evaluate odds of wheeze in the past year among the 20898 farmers who provided complete information on all covariates. Driving diesel tractors was associated with elevated odds of wheeze (odds ratio = 1.31; 95% confidence interval = 1.13, 1.52); the odds ratio for driving gasoline tractors was 1.11 (95% confidence interval = 1.02, 1.21). A duration-response relationship was observed for driving diesel tractors but not for driving gasoline tractors. Activities involving solvent exposure, including painting and use of solvents for cleaning, were associated with an increased odds of wheeze in a duration-dependent fashion. The highest odds of wheeze for farm activities were for daily painting (odds ratio = 1.82; 95% confidence interval = 0.89, 3.73), an indication of daily solvent exposure. These results add to the growing body of evidence of adverse respiratory effects of diesel exposure on the lung and suggest exposure to solvents may contribute as well.

Replication is an important step in evaluating evidence-based preventive interventions and is crucial for establishing the generalizability and wider impact of a program. Despite this, few replications have occurred in the prevention science field. This study aims to fill this gap by conducting a cross-validation trial of the Climate Schools: Alcohol and Cannabis course, an Internet-based prevention program, among a new cohort of Australian students. A cluster randomized controlled trial was conducted among 1103 students (Mage: 13.25 years) from 13 schools in Australia in 2012. Six schools received the Climate Schools course and 7 schools were randomized to a control group (health education as usual). All students completed a self-report survey at baseline and immediately post-intervention. Mixed-effects regressions were conducted for all outcome variables. Outcomes assessed included alcohol and cannabis use, knowledge and intentions to use these substances. Compared to the control group, immediately post-intervention the intervention group reported significantly greater alcohol (d = 0.67) and cannabis knowledge (d = 0.72), were less likely to have consumed any alcohol (even a sip or taste) in the past 6 months (odds ratio = 0.69) and were less likely to intend on using alcohol in the future (odds ratio = 0.62). However, there were no effects for binge drinking, cannabis use or intentions to use cannabis. These preliminary results provide some support for the Internet-based Climate Schools: Alcohol and Cannabis course as a feasible way of delivering alcohol and cannabis prevention. Intervention effects for alcohol and cannabis knowledge were consistent with results from the original trial; however, analyses of longer-term follow-up data are needed to provide a clearer indication of the efficacy of the intervention, particularly in relation to behavioral changes. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Estimates of association between exposures and diseases are often distorted by error in exposure classification. When the validity of exposure assessment is known, this can be used to adjust these estimates. When exposure is assessed by experts, even if validity is not known, we sometimes have information about interrater reliability. We present a Bayesian method for translating the knowledge of interrater reliability, which is often available, into knowledge about validity, which is often needed but not directly available, and applying this to correct odds ratios (OR). The method allows for inclusion of observed potential confounders in the analysis, as is common in regression-based control for confounding. Our method uses a novel type of prior on sensitivity and specificity. The approach is illustrated with data from a case-control study of lung cancer risk and occupational exposure to diesel engine emissions, in which exposure assessment was made by detailed job history interviews with study subjects followed by expert judgement. Using interrater agreement measured by kappas (κ), we estimate sensitivity and specificity of exposure assessment and derive misclassification-corrected confounder-adjusted OR. Misclassification-corrected and confounder-adjusted OR obtained with the most defensible prior had a posterior distribution centre of 1.6 with 95% credible interval (Crl) 1.1 to 2.6. This was on average greater in magnitude than frequentist point estimate of 1.3 (95% Crl 1.0 to 1.7). The method yields insights into the degree of exposure misclassification and appears to reduce attenuation bias due to misclassification of exposure while the estimated uncertainty increased. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Objective: The aim of this study was to evaluate the past attendance for cervical cancer screening with knowledge of risk factors, access to health-related information, health profiles and health competence beliefs among Japanese women. Methods: Women ages 25, 30, 35, 40, 45, 50, 55, and 60 were contacted cross-sectionally as part of a project for the Japanese Ministry of Health, Labour and Welfare in Nikaho, Akita prefecture Japan between June 2010 and March 2011, and 249 women were analyzed for the current study. The questionnaire asked about past cervical cancer screening. Knowledge of each cervical cancer risk factor was determined on a four-point scale. A barriers to information access scale was utilized to assess the degree of difficulty in accessing health-related information. Health profiles were measured using the EuroQOL EQ-5D. Perceived health competence was measured using a scale (PHCS). The association was evaluated with odds ratios with 95% confidence interval were calculated from a logistic regression analysis after adjustment for age and potential confounders. The trend across the level was also assessed. Results: Women who knew that sexual intercourse at young age was a risk factor were significantly more likely to have participated in cervical cancer screening sometime in their lives (p for trend =0.02). Women who had pain/discomfort and those who had anxiety/depression were significantly more likely to have participated in cervical screening within the past two years (odds ratio [OR]: 2.02, 95% confidence interval [CI]: 1.04–3.94; OR: 2.32, 95% CI: 1.05–5.16, respectively). Women with higher PHCS were significantly more likely to have attended for cervical screened at some point in their lives (p=0.04). Conclusion: This study observed that specific knowledge of cervical cancer risk factors, health profiles and PHCS were associated with the past attendance for cervical cancer screening among women in a community. Further researches are warranted. PMID:28843231

This study aims to assess whether the timing of menopausal hormone therapy initiation in relation to onset of menopause and hormone therapy duration is associated with myocardial infarction risk. This study was based on the Stockholm Heart Epidemiology Program, a population-based case-control study including 347 postmenopausal women who had experienced a nonfatal myocardial infarction and 499 female control individuals matched for age and residential area. Odds ratios (with 95% CIs) for myocardial infarction were calculated using logistic regression. Early initiation of hormone therapy (within 10 y of onset of menopause or before age 60 y), compared with never use, was associated with an odds ratio of 0.87 (95% CI, 0.58-1.30) after adjustments for lifestyle factors, body mass index, and socioeconomic status. For late initiation of hormone therapy, the corresponding odds ratio was 0.97 (95% CI, 0.53-1.76). For hormone therapy duration of 5 years or more, compared with never use, the adjusted odds ratio was 0.64 (95% CI, 0.35-1.18). For hormone therapy duration of less than 5 years, the odds ratio was 0.97 (95% CI, 0.63-1.48). Neither the timing of hormone therapy initiation nor the duration of therapy is significantly associated with myocardial infarction risk.

It is important to ingest just proportions of minerals to prevent disease, but these minerals are also secreted into the hair. Meanwhile, the number of hay fever patients in Japan is increasing, causing an increase in national medical expenses. In this study, we investigated the relationship between hay fever and mineral concentrations in hair to obtain findings on the risk of developing pollen allergies. A questionnaire survey was conducted for 275 men and 977 women on their lifestyle habits and ten kinds of mineral concentrations present in their hair were measured with subsequent analysis using nominal logistic regression analysis. The results indicated that half the patients in each age group had hay fever, with no significant difference between hay fever and aging, exercise habits, sleep and dietary rhythms. On the other hand, there was a significant difference between hay fever and mineral concentrations in the hair, and in men with hay fever, iron (odds ratio: 0.55, p<0.05) was low, while in women calcium (odds ratio: 0.67, p<0.05), chromium (odds ratio: 0.46, p<0.001), cadmium (odds ratio: 0.68, p<0.01) were low and selenium (odds ratio: 1.78, p<0.01) was high. These results, suggest that measurements mineral concentrations in hair are indicators of hay fever risk.

The aim of this study was to investigate the associations between dental knowledge, the source of dental knowledge and oral health behavior in a group of students at a university in Japan. A total of 2,220 university students (1,276 males, 944 females) volunteered to undergo an oral examination and answer a questionnaire. The questionnaire assessed dental knowledge, the source of dental knowledge and oral health behavior (e.g., daily frequency of tooth brushing, use of dental floss and regular dental checkups). The odds ratio and 95% confidence interval for oral health behavior based on dental knowledge and source of dental knowledge were calculated using logistic regression models. Of the participants, 1,266 (57.0%) students obtained dental knowledge from dental clinics, followed by school (39.2%) and television (29.1%). Logistic regression analyses indicated that use of dental floss was significantly associated with source of dental knowledge from dental clinics (P = 0.006). Receiving regular dental checkups was significantly associated with source of dental knowledge; the positive source was dental clinic (P < 0.001) and the negative sources were school (P = 0.004) and television (P = 0.018). Dental clinic was the most common source of dental knowledge and associated with better oral health behavior among the Japanese university students in this study. PMID:28594914

The Water and Sanitation Extension Programme (WASEP) project, undertaken in selected villages in northern Pakistan between 1997 and 2001, was designed to deliver an integrated package of activities to improve potable water supply at village and household levels, sanitation facilities and their use, and awareness and practices about hygiene behaviour. METHODS: A case-control study was conducted during July-September 2001 to evaluate whether, after selected confounders were controlled for, children aged <6 years with diarrhoea were more or less likely to reside in villages that participated in the project than in villages that did not participate. Descriptive and logistic regression analyses were performed. FINDINGS: Children not living in WASEP villages had a 33% higher adjusted odds ratio for having diarrhoea than children living in WASEP villages (adjusted odds ratio, 1.331; P<0.049). Boys had 25% lower odds of having diarrhoea than girls (adjusted odds ratio, 0.748; P<0.049). A 2.6% decrease was found in the odds of diarrhoea for every yearly increase in the mother's age (adjusted odds ratio, 0.974; P<0.044) and a 1.4% decrease for every monthly increase in the child's age (adjusted odds ratio, 0.986; P<0.001). CONCLUSIONS: The findings in this study may help refine the approach to future water, sanitation, and hygiene initiatives in northern Pakistan. The integrated approach taken by WASEP, which incorporates engineering solutions with appropriate education to maximize facility usage and improve hygiene practices, is a useful example of how desired health benefits can be obtained from projects of this type.

Longitudinal studies that have examined the association of insomnia with incident depression using objective sleep measures are very limited. The aim of this study was to examine the predictive role of the severity of insomnia for incident depression in a general population sample using psychometric and polysomnographic data. From a random, general population sample of 1741 individuals of the Penn State Adult Cohort, 1137 adults without depression were followed up with a structured telephone interview after 7.5 years. All subjects completed a full medical evaluation, 1-night polysomnogram and Multiphasic Minnesota Personality Inventory at baseline. The incidence of depression was 15%. Poor sleep (odds ratio = 1.5, P = 0.001) and insomnia (odds ratio = 1.9, P = 0.031) were significantly associated with incident depression. The odds of incident depression were highest (odds ratio = 2.2, P = 0.019) in insomnia with objective short sleep duration and independent of Multiphasic Minnesota Personality Inventory Ego Strength scores, an index of poor coping resources. The persistence of insomnia and worsening of poor sleep into insomnia significantly increased the odds of incident depression (odds ratios ranged from 1.8 to 6.3), whereas their full remission did not (odds ratio ranged from 1.2 to 1.8). Insomnia with short sleep duration is associated with incident depression independent of poor coping resources, whereas the association of insomnia with normal sleep duration with incident depression was mediated by poor coping resources. Persistence and worsening of poor sleep or insomnia, but not their full remission, are significant predictors of incident depression. These data suggest that there is a significant relationship between the severity of insomnia and incident depression. © 2015 European Sleep Research Society.

Gestational weight gain above or below the 2009 National Academy of Medicine guidelines has been associated with adverse maternal and neonatal outcomes. Although it has been well established that excess gestational weight gain is associated with the development of gestational hypertension and preeclampsia, the relationship between gestational weight gain and adverse perinatal outcomes among women with pregestational (chronic) hypertension is less clear. The objective of this study was to examine the relationship between gestational weight gain above and below National Academy of Medicine guidelines and perinatal outcomes in a large, population-based cohort of women with chronic hypertension. This is a population-based retrospective cohort study of women with chronic hypertension who had term, singleton, vertex births in the United States from 2012 through 2014. Prepregnancy body mass index was calculated using self-reported prepregnancy weight and height. Women were categorized into 4 groups based on gestational weight gain and prepregnancy body mass index: (1) weight gain less than, (2) weight gain within, (3) weight gain 1-19 lb in excess of, and (4) weight gain ≥20 lb in excess of the National Academy of Medicine guidelines. The χ 2 tests and multivariable logistic regression analysis were used for statistical comparisons. Stratified analyses by body mass index category were additionally performed. In this large birth cohort, 101,259 women met criteria for inclusion. Compared to hypertensive women who had gestational weight gain within guidelines, hypertensive women with weight gain ≥20 lb over National Academy of Medicine guidelines were more likely to have eclampsia (adjusted odds ratio, 1.93; 95% confidence interval, 1.54-2.42) and cesarean delivery (adjusted odds ratio, 1.60; 95% confidence interval, 1.50-1.70). Excess weight gain ≥20 lb over National Academy of Medicine guidelines was also associated with increased odds of 5-minute Apgar <7 (adjusted odds ratio, 1.29; 95% confidence interval, 1.13-1.47), neonatal intensive care unit admission (adjusted odds ratio, 1.23; 95% confidence interval, 1.14-1.33), and large-for-gestational-age neonates (adjusted odds ratio, 2.41; 95% confidence interval, 2.27-2.56) as well as decreased odds of small-for-gestational-age status (adjusted odds ratio, 0.52; 95% confidence interval, 0.46-0.58). Weight gain 1-19 lb over guidelines was associated with similar fetal growth outcomes although with a smaller effect size. In contrast, weight gain less than National Academy of Medicine guidelines was not associated with adverse maternal outcomes but was associated with increased odds of small for gestational age (adjusted odds ratio, 1.31; 95% confidence interval, 1.21-1.52) and decreased odds of large-for-gestational-age status (adjusted odds ratio, 0.86; 95% confidence interval, 0.81-0.92). Analysis of maternal and neonatal outcomes stratified by body mass index demonstrated similar findings. Women with chronic hypertension who gain less weight than National Academy of Medicine guidelines experience increased odds of small-for-gestational-age neonates, whereas excess weight gain ≥20 lb over National Academy of Medicine guidelines is associated with cesarean delivery, eclampsia, 5-minute Apgar <7, neonatal intensive care unit admission, and large-for-gestational-age neonates.

Recently, it has been suggested that screening mammography may result in some degree of overdiagnosis (ie, detection of breast cancers that would never become clinically important within the lifespan of the patient). The extent and biology of these overdiagnosed cancers, however, is not well understood, and the effect of newer screening modalities on overdiagnosis is unknown. We performed a retrospective review of a prospectively collected database of breast cancers diagnosed at the Yale Breast Center from 2004-2014. The mode of initial presentation was categorized into 5 groups: screening mammogram, screening magnetic resonance imaging, screening ultrasonography, self-detected masses, and physician-detected masses. Compared with cancers presenting with masses, cancers detected by image-based screening were more likely to present with ductal carcinoma-in-situ or T1 cancers (P < .001). In addition to a simple stage shift, however, cancers detected by image-based screening were also more likely to be luminal and low-grade cancers; symptomatic cancers were more likely high-grade and triple-negative (P < .001, respectively). On a multivariate analysis, adjusting for age, race, and tumor size, cancers detected by mammogram, US, and magnetic resonance imaging had greater odds of being luminal (odds ratio 1.8, 95% confidence interval, 1.5-2.3; odds ratio 2.2, 95% confidence interval, 1.1-4.7; and odds ratio 4.7, 95% confidence interval, 2.1-10.6, respectively), and low-grade (odds ratio 2.2, 95% confidence interval, 1.6-2.9; odds ratio 4.9, 95% confidence interval, 2.7-8.9; and odds ratio 4.6, 95% confidence interval, 2.6-8.1, respectively) compared with cancers presenting with self-detected masses. Screening detects cancers with more indolent biology, potentially contributing to the observed rate of overdiagnosis. With magnetic resonance imaging and US being used more commonly for screening, the rate of overdiagnosis may increase further. Copyright © 2016. Published by Elsevier Inc.

Major depressive disorder (MDD) is underdiagnosed and undertreated in schizophrenia, and has been strongly associated with impaired quality of life.AimsTo determine the prevalence and associated factors of MDD and unremitted MDD in schizophrenia, to compare treated and non-treated MDD. Participants were included in the FondaMental Expert Centers for Schizophrenia and received a thorough clinical assessment. MDD was defined by a Calgary score ≥6. Non-remitted MDD was defined by current antidepressant treatment (unchanged for >8 weeks) and current Calgary score ≥6. 613 patients were included and 175 (28.5%) were identified with current MDD. MDD has been significantly associated with respectively paranoid delusion (odds ratio 1.8; P = 0.01), avolition (odds ratio 1.8; P = 0.02), blunted affect (odds ratio 1.7; P = 0.04) and benzodiazepine consumption (odds ratio 1.8; P = 0.02). Antidepressants were associated with lower depressive symptoms score (5.4 v. 9.5; P < 0.0001); however, 44.1% of treated patients remained in non-remittance MDD. Nonremitters were found to have more paranoid delusion (odds ratio 2.3; P = 0.009) and more current alcohol misuse disorder (odds ratio 4.8; P = 0.04). No antidepressant class or specific antipsychotic were associated with higher or lower response to antidepressant treatment. MDD was associated with Metabolic syndrome (31.4 v. 20.2%; P = 0.006) but not with increased C-reactive protein. Antidepressant administration is associated with lower depressive symptom level in patients with schizophrenia and MDD. Paranoid delusions and alcohol misuse disorder should be specifically explored and treated in cases of non-remission under treatment. MetS may play a role in MDD onset and/or maintenance in patients with schizophrenia.Declaration of interestNone.

There has been concern that a reduced level of surgical resident supervision in the operating room (OR) is correlated with worse patient outcomes. Until September 2004, Veterans' Affairs (VA) hospitals entered in the surgical record level 3 supervision on every surgical case when the attending physician was available but not physically present in the OR or the OR suite. In this study, we assessed the impact of level 3 on risk-adjusted morbidity and mortality in the VA system. Surgical cases entered into the National Surgical Quality Improvement Program database between 1998 and 2004, from 99 VA teaching facilities, were included in a logistic regression analysis for each year. Level 3 versus all other levels of supervision were forced into the model, and patient characteristics then were selected stepwise to arrive at a final model. Confidence limits for the odds ratios were calculated by profile likelihood. A total of 610,660 cases were available for analysis. Thirty-day mortality and morbidity rates were reported in 14,441 (2.36%) and 63,079 (10.33%) cases, respectively. Level 3 supervision decreased from 8.72% in 1998 to 2.69% in 2004. In the logistic regression analysis, the odds ratios for mortality for level 3 ranged from .72 to 1.03. Only in the year 2000 were the odds ratio for mortality statistically significant at the .05 level (odds ratio, .72; 95% confidence interval, .594-.858). For morbidity, the odds ratios for level 3 supervision ranged from .66 to 1.01, and all odds ratios except for the year 2004 were statistically significant. Between 1998 and 2004, the level of resident supervision in the OR did not affect clinical outcomes adversely for surgical patients in the VA teaching hospitals.

Objectives The Great East Japan Earthquake caused a gigantic tsunami which devastated coastal areas of northern Japan on 11 March 2011. Despite the large number of ‘resident survivors’ who continued to reside in their damaged houses on the second or upper floors, research on the mental health of these individuals has been limited. This study explored the prevalence of depressive reaction and risk factors for depressive reaction among these resident survivors. Methods A cross-sectional household health support needs screening was conducted for resident survivors in Higashi-Matsushima city, Miyagi prefecture, two to four months after the tsunami. The health interview that was conducted including mental status, assessed by the Patient Health Questionnaire-2 (PHQ-2). Results Of 5,454 respondents, 8.1% had depressive reaction. After adjustment by the number of weeks from the tsunami and the mortality rate at each respondent's place of residence, depressive reaction was significantly associated with house flooding below or above the ground floor (odds ratios of 1.92, 2.36, respectively), the unavailability of gas supply (odds ratio, 1.67), being female (odds ratio, 1.47), middle aged or elderly (odds ratios of 2.41, 2.42, respectively), regular intake of psychotropic medicine(s) since before the tsunami (odds ratio, 2.53) and the presence of one to five or more than six cohabiters (odds ratios of 0.61, 0.52, respectively). Conclusions The results suggest a considerable psychological burden (depressive reaction) following the tsunami among resident survivors. Special supports for families with psychiatric problems need to be considered among resident survivors. Restoration of lifeline utilities and the strengthening of social ties of persons living alone may help prevent depressive reaction among resident survivors after a tsunami. PMID:25279563

The purpose of this study was to evaluate the effectiveness of antibiotic treatment of bacterial vaginosis in pregnancy to reduce preterm delivery. We performed a meta-analysis of published, English-language, randomized, placebo-controlled clinical trials of antibiotic treatment of bacterial vaginosis in pregnant women with intact amniotic membranes at <37 weeks of gestation. Primary outcomes included preterm delivery, perinatal or neonatal death, and neonatal morbidity. Ten studies with results for 3969 patients were included. In patients without preterm labor, antibiotic treatment did not significantly decrease preterm delivery at <37 weeks of gestation, in all patients combined (odds ratio, 0.83; 95% CI, 0.57-1.21) nor in high-risk patients with a previous preterm delivery (odds ratio, 0.50; 95% CI, 0.22-1.12). In both groups, significant statistical heterogeneity was observed. A significant reduction in preterm delivery and no statistical heterogeneity were observed in 338 high-risk patients who received oral regimens with treatment durations of > or =7 days (odds ratio, 0.42; 95% CI, 0.27-0.67). Nonsignificant effects and no statistical heterogeneity were observed in low-risk patients (odds ratio, 0.94; 95% CI, 0.71-1.25) and with vaginal regimens (odds ratio, 1.25; 95% CI: 0.86-1.81). In one study antibiotic treatment in patients with preterm labor led to a nonsignificant decrease in the rate of preterm deliveries (odds ratio, 0.31; 95% CI, 0.03-3.24). The screening of pregnant women who have bacterial vaginosis and who have had a previous preterm delivery and treatment with an oral regimen of longer duration can be justified on the basis of current evidence. More studies are needed to confirm the effectiveness of this strategy, both in high-risk patients without preterm labor and in patients with preterm labor.

Zolpidem is one of the most frequently used hypnotics worldwide, but associations with serious adverse effects such as motor vehicle collisions have been reported. The objective of this study was to evaluate the association of fatal motor vehicle collisions with a prescription for zolpidem, considering the context of the motor vehicle collisions. We conducted a case-crossover study, where each case served as its own control, by linking data about fatal motor vehicle collisions from the Korean Road Traffic Authority between 2010 and 2014 with national health insurance data. The case period was defined as 1 day before the fatal motor vehicle collisions, and was matched to four control periods at 90-day intervals. Conditional logistic regression was performed to calculate the odds ratio for fatal motor vehicle collisions associated with zolpidem exposure, and odds ratios were adjusted for time-varying exposure to confounding medications. A stratified analysis was performed by age group (younger than 65 years or not), the Charlson Comorbidity Index, and whether patients were new zolpidem users. Among the 714 subjects, the adjusted odds ratio for a fatal motor vehicle collision associated with a prescription for zolpidem the previous day was 1.48 (95% confidence interval 1.06-2.07). After stratification, a significantly increased risk was observed in subjects with a high Charlson Comorbidity Index (odds ratio 1.81; 95% confidence interval 1.16-2.84), the younger age group (odds ratio: 1.62; 95% confidence interval 1.03-2.56), and new zolpidem users (odds ratio 2.37; 95% confidence interval 1.40-4.00). A prescription for zolpidem on the previous day was significantly related to an increased risk of fatal motor vehicle collisions in this population-based case-crossover study.

Context Knowing the prevalence and risk factors of immunosuppression nonadherence after liver transplant may help guide intervention development. Objective To examine whether sociodemographic and psychosocial variables before liver transplant are predictive of nonadherence after liver transplant. Design Structured telephone interviews were used to collect self-report immunosuppression adherence and health status information. Medical record reviews were then completed to retrospectively examine the relationship between immunosuppression adherence and pretransplant variables, including sociodemographic and medical characteristics and the presence or absence of 6 hypothesized psychosocial risk factors. Setting and Participants A nonprobability sample of 236 adults 6 to 24 months after liver transplant at 2 centers completed structured telephone interviews. Main Outcome Measure Immunosuppressant medication nonadherence, categorized as missed-dose and altered-dose “adherent” or “nonadherent” during the past 6 months; immunosuppression medication holidays. Results Eighty-two patients (35%) were missed-dose nonadherent and 34 patients (14%) were altered-dose nonadherent. Seventy-one patients (30%) reported 1 or more 24-hour immunosuppression holidays in the past 6 months. Missed-dose nonadherence was predicted by male sex (odds ratio, 2.46; P = .01), longer time since liver transplant (odds ratio, 1.08; P = .01), pretransplant mood disorder (odds ratio, 2.52; P = .004), and pretransplant social support instability (odds ratio, 2.25; P = .03). Altered-dose nonadherence was predicted by pretransplant mood disorder (odds ratio, 2.15; P = .04) and pretransplant social support instability (odds ratio, 1.89; P = .03). Conclusion Rates of immunosuppressant nonadherence and drug holidays in the first 2 years after liver transplant are unacceptably high. Pretransplant mood disorder and social support instability increase the risk of nonadherence, and interventions should target these modifiable risk factors. PMID:24311395

Case-chaos methodology is a proposed alternative to case-control studies that simulates controls by randomly reshuffling the exposures of cases. We evaluated the method using data on outbreaks in Sweden. We identified 5 case-control studies from foodborne illness outbreaks that occurred between 2005 and 2012. Using case-chaos methodology, we calculated odds ratios 1,000 times for each exposure. We used the median as the point estimate and the 2.5th and 97.5th percentiles as the confidence interval. We compared case-chaos matched odds ratios with their respective case-control odds ratios in terms of statistical significance. Using Spearman's correlation, we estimated the correlation between matched odds ratios and the proportion of cases exposed to each exposure and quantified the relationship between the 2 using a normal linear mixed model. Each case-control study identified an outbreak vehicle (odds ratios = 4.9-45). Case-chaos methodology identified the outbreak vehicle 3 out of 5 times. It identified significant associations in 22 of 113 exposures that were not associated with outcome and 5 of 18 exposures that were significantly associated with outcome. Log matched odds ratios correlated with their respective proportion of cases exposed (Spearman ρ = 0.91) and increased significantly with the proportion of cases exposed (b = 0.054). Case-chaos methodology missed the outbreak source 2 of 5 times and identified spurious associations between a number of exposures and outcome. Measures of association correlated with the proportion of cases exposed. We recommended against using case-chaos analysis during outbreak investigations. © The Author 2014.

To assess protective and risk factors for mortality among pediatric patients during initial care after hematopoietic stem cell transplantation (HSCT) and to evaluate changes in hospital mortality. Retrospective cohort using the 1997, 2000, and 2003 Kids Inpatient Database, a probabilistic sample of children hospitalized in the United States with a procedure code for HSCT. Hospitalized patients in the United States submitted to the database. Age, <19 yrs. None. Hospital mortality significantly decreased from 12% in 1997 to 6% in 2003. Source of stem cells changed with increased use of cord blood. Rates of sepsis, graft versus host disease, and mechanical ventilation significantly decreased. Compared with autologous HSCT, patients who received an allogenic HSCT without T-cell depletion were more likely to die (adjusted odds ratio, 2.4; 95% confidence interval, 1.5, 3.9), while children who received cord blood HSCT were at the greatest risk of hospital death (adjusted odds ratio, 4.8; 95% confidence interval, 2.6, 9.1). Mechanical ventilation (adjusted odds ratio, 26.32; 95% confidence interval, 16.3-42.2), dialysis (adjusted odds ratio, 12.9; 95% confidence interval, 4.7-35.4), and sepsis (adjusted odds ratio, 3.9; 95% confidence interval, 2.5-6.1) were all independently associated with death, while care in 2003 was associated with decreased risk (adjusted odds ratio, 0.4; 95% confidence interval, 0.2-0.7) of death. Hospital mortality after HSCT in children decreased over time as did complications including need for mechanical ventilation, graft versus host disease, and sepsis. Prevention of complications is essential as the need for invasive support continues to be associated with high mortality risk.

Contaminated food ingredients can affect multiple products, each distributed through various channels and consumed in multiple settings. Beginning in November 2008, we investigated a nationwide outbreak of salmonella infections. A case was defined as laboratory-confirmed infection with the outbreak strain of Salmonella Typhimurium occurring between September 1, 2008, and April 20, 2009. We conducted two case-control studies, product "trace-back," and environmental investigations. Among 714 case patients identified in 46 states, 166 (23%) were hospitalized and 9 (1%) died. In study 1, illness was associated with eating any peanut butter (matched odds ratio, 2.5; 95% confidence interval [CI], 1.3 to 5.3), peanut butter-containing products (matched odds ratio, 2.2; 95% CI, 1.1 to 4.7), and frozen chicken products (matched odds ratio, 4.6; 95% CI, 1.7 to 14.7). Investigations of focal clusters and single cases associated with nine institutions identified a single institutional brand of peanut butter (here called brand X) distributed to all facilities. In study 2, illness was associated with eating peanut butter outside the home (matched odds ratio, 3.9; 95% CI, 1.6 to 10.0) and two brands of peanut butter crackers (brand A: matched odds ratio, 17.2; 95% CI, 6.9 to 51.5; brand B: matched odds ratio, 3.6; 95% CI, 1.3 to 9.8). Both cracker brands were made from brand X peanut paste. The outbreak strain was isolated from brand X peanut butter, brand A crackers, and 15 other products. A total of 3918 peanut butter-containing products were recalled between January 10 and April 29, 2009. Contaminated peanut butter and peanut products caused a nationwide salmonellosis outbreak. Ingredient-driven outbreaks are challenging to detect and may lead to widespread contamination of numerous food products.

Advanced maternal age is associated with higher frequencies of antenatal and perinatal conditions, as well as a higher risk of cerebral palsy in offspring. We explore the association between maternal age and specific cerebral palsy risk factors. Data were extracted from the Canadian Cerebral Palsy Registry. Maternal age was categorized as ≥35 years of age and less than 20 years of age at the time of birth. Chi-square and multivariate logistic regressions were performed to calculate odds ratios and their 95% confidence intervals. The final sample consisted of 1391 children with cerebral palsy, with 19% of children having mothers aged 35 or older and 4% of children having mothers below the age of 20. Univariate analyses showed that mothers aged 35 or older were more likely to have gestational diabetes (odds ratio 1.9, 95% confidence interval 1.3 to 2.8), to have a history of miscarriage (odds ratio 1.8, 95% confidence interval 1.3 to 2.4), to have undergone fertility treatments (odds ratio 2.4, 95% confidence interval 1.5 to 3.9), and to have delivered by Caesarean section (odds ratio 1.6, 95% confidence interval 1.2 to 2.2). These findings were supported by multivariate analyses. Children with mothers below the age of 20 were more likely to have a congenital malformation (odds ratio 2.4, 95% confidence interval 1.4 to 4.2), which is also supported by multivariate analysis. The risk factor profiles of children with cerebral palsy vary by maternal age. Future studies are warranted to further our understanding of the compound causal pathways leading to cerebral palsy and the observed greater prevalence of cerebral palsy with increasing maternal age.

Non-restorative sleep is a hallmark symptom of chronic fatigue syndrome/myalgic encephalomyelitis. However, little is known about self-reported sleep disturbances in these subjects. This study aimed to assess the self-reported sleep quality and its impact on quality of life in a Spanish community-based chronic fatigue syndrome/myalgic encephalomyelitis cohort. A prospective cross-sectional cohort study was conducted in 1,455 Spanish chronic fatigue syndrome/myalgic encephalomyelitis patients. Sleep quality, fatigue, pain, functional capacity impairment, psychopathological status, anxiety/depression and health-related quality of life were assessed using validated subjective measures. The frequencies of muscular, cognitive, neurological, autonomic and immunological symptom clusters were above 80%. High scores were recorded for pain, fatigue, psychopathological status, anxiety/depression, and low scores for functional capacity and quality of life, all of which correlated significantly (all p < 0.01) with quality of sleep as measured by the Pittsburgh Sleep Quality Index. Multivariate regression analysis showed that after adjusting for age and gender, the pain intensity (odds ratio, 1.11; p <0.05), psychopathological status (odds ratio, 1.85; p < 0.001), fibromyalgia (odds ratio, 1.39; p < 0.05), severe autonomic dysfunction (odds ratio, 1.72; p < 0.05), poor functional capacity (odds ratio, 0.98; p < 0.05) and quality of life (odds ratio, 0.96; both p < 0.001) were significantly associated with poor sleep quality. These findings suggest that this large chronic fatigue syndrome/myalgic encephalomyelitis sample presents poor sleep quality, as assessed by the Pittsburgh Sleep Quality Index, and that this poor sleep quality is associated with many aspects of quality of life. © 2018 European Sleep Research Society.

Background and objectives Behavioral stage of change (SoC) algorithms classify patients’ readiness for medical treatment decision-making. In the precontemplation stage, patients have no intention to take action within 6 months. In the contemplation stage, action is intended within 6 months. In the preparation stage, patients intend to take action within 30 days. In the action stage, the change has been made. This study examines the influence of SoC on dialysis modality decision-making. Design, setting, participants, & measurements SoC and relevant covariates were measured, and associations with dialysis decision-making were determined. In-depth interviews were conducted with 16 patients on dialysis to elicit experiences. Qualitative interview data informed the survey design. Surveys were administered to adults with CKD (eGFR≤25 ml/min/1.73 m2) from August, 2012 to June, 2013. Multivariable logistic regression modeled dialysis decision-making with predictors: SoC, provider connection, and dialysis knowledge score. Results Fifty-five patients completed the survey (71% women, 39% white, and 59% black), and median annual income was $17,500. In total, 65% of patients were in the precontemplation/contemplation (thinking) and 35% of patients were in the preparation/maintenance (acting) SoC; 62% of patients had made dialysis modality decisions. Doctors explaining modality options, higher dialysis knowledge scores, and fewer lifestyle barriers were associated with acting versus thinking SoC (all P<0.02). Patients making modality decisions had doctors who explained dialysis options (76% versus 43%), were in the acting versus the thinking SoC (50% versus 10%), had higher dialysis knowledge scores (1.4 versus 0.5), and had lower eGFR (13.9 versus 16.8 ml/min/1.73 m2; all P<0.05). In adjusted analyses, dialysis knowledge was significantly associated with decision-making (odds ratio, 4.2; 95% confidence interval, 1.4 to 12.9; P=0.01), and SoC was of borderline significance (odds ratio, 5.8; 95% confidence interval, 1.0 to 32.6; P=0.05). The model C statistic was 0.87. Conclusions Dialysis decision-making was associated with SoC, dialysis knowledge, and physicians discussing treatment options. Future studies determining ways to assist patients with CKD in making satisfying modality decisions are warranted. PMID:25591499

Background Most incorrect diagnoses involve at least one cognitive error, of which premature closure is the most prevalent. While metacognitive strategies can mitigate premature closure in inexperienced learners, these are rarely studied in experienced physicians. Our objective here was to evaluate the effect of analytic information processing on diagnostic performance of nephrologists and nephrology residents. Methods We asked nine nephrologists and six nephrology residents at the University of Calgary and Glasgow University to diagnose ten nephrology cases. We provided presenting features along with contextual information, after which we asked for an initial diagnosis. We then primed participants to use either hypothetico-deductive reasoning or scheme-inductive reasoning to analyze the remaining case data and generate a final diagnosis. Results After analyzing initial hypotheses, both nephrologists and residents improved the accuracy of final diagnoses (31.1% vs. 65.6%, p < 0.001, and 40.0% vs. 70.0%, p < 0.001, respectively). We found a significant interaction between experience and analytic processing strategy (p = 0.02): nephrology residents had significantly increased odds of diagnostic success when using scheme-inductive reasoning (odds ratio [95% confidence interval] 5.69 [1.59, 20.33], p = 0.07), whereas the performance of experienced nephrologists did not differ between strategies (odds ratio 0.57 [0.23, 1.39], p = 0.20). Discussion Experienced nephrologists and nephrology residents can improve their performance by analyzing initial diagnostic hypotheses. The explanation of the interaction between experience and the effect of different reasoning strategies is unclear, but may relate to preferences in reasoning strategy, or the changes in knowledge structure with experience.

This study examined illness representations of new influenza Human Swine Influenza A (H1N1) and association with H1N1 preventive behaviors among 300 Chinese adults using a population-based randomized telephone survey. Results showed that relatively few participants thought H1N1 would have serious consequences (12%-15.7%) and few showed negative emotional responses toward H1N1 (9%-24.7%). The majority of the participants thought H1N1 could be controlled by treatment (70.4%-72.7%). Multiple logistic regression analyses showed that treatment control (odds ratio = 1.78) and psychological attribution (odds ratio = .75) were associated with intention to take up influenza vaccination. Emotional representations were associated with lower likelihood of wearing face mask (odds ratio = .77) and hand washing (odds ratio = .67). Results confirm that illness representation variables are associated with H1N1 preventive behaviors. © The Author(s) 2014.

The purpose of this study was to assess the association of calcium replacement therapy with morbidity and mortality in infants after cardiac surgery involving cardiopulmonary bypass. Retrospective chart review. The cardiac intensive care unit at a tertiary care children's hospital. Infants undergoing cardiac surgery involving cardiopulmonary bypass between October 2002 and August 2004. None. Total calcium replacement (mg/kg calcium chloride given) for the first 72 postoperative hours was measured. Morbidity and mortality data were collected. The total volume of blood products given during the first 72 hrs was recorded. Infants with confirmed chromosomal deletions at the 22q11 locus were noted. Correlation and logistic regression analyses were used to generate odds ratios and 95% confidence intervals, with p < .05 being significant. One hundred seventy-one infants met inclusion criteria. Age was 4 +/- 3 months and weight was 4.9 +/- 1.7 kg at surgery. Six infants had deletions of chromosome 22q11. Infants who weighed less required more calcium replacement (r = -.28, p < .001). Greater calcium replacement correlated with a longer intensive care unit length of stay (r = .27, p < .001) and a longer total hospital length of stay (r = .23, p = .002). Greater calcium replacement was significantly associated with morbidity (liver dysfunction [odds ratio, 3.9; confidence interval, 2.1-7.3; p < .001], central nervous system complication [odds ratio, 1.8; confidence interval, 1.1-3.0; p = .02], infection [odds ratio, 1.5; confidence interval, 1.0-2.2; p < .04], extracorporeal membrane oxygenation [odds ratio, 5.0; confidence interval, 2.3-10.6; p < .001]) and mortality (odds ratio, 5.8; confidence interval, 5.8-5.9; p < .001). Greater calcium replacement was not associated with renal insufficiency (odds ratio, 1.5; confidence interval, 0.9-2.3; p = .07). Infants with >1 sd above the mean of total calcium replacement received on average fewer blood products than the total study population. Greater calcium replacement is associated with increasing morbidity and mortality. Further investigation of the etiology and therapy of hypocalcemia in this population is warranted.

The authors sought to determine whether pregnancy is an intrinsic motivator for cessation of drug abuse. The authors conducted prospective cohort, co-relative, co-spouse, and within-person analyses of registration for drug abuse during pregnancy among Swedish women born between 1980 and 1990 who gave birth between ages 20 and 35 (N=149,512). Drug abuse was assessed from medical, criminal, and pharmacy registries. In the population, rates of drug abuse were lower during pregnancy (unadjusted odds ratio=0.67, 95% CI=0.60, 0.74). Compared with population results, the negative association between pregnancy and drug abuse was moderately stronger in cousins (odds ratio=0.49, 95% CI=0.39, 0.62) and substantially stronger in siblings (odds ratio=0.35, 95% CI=0.24, 0.51) discordant for pregnancy. The estimated odds ratio for drug abuse in pregnancy-discordant monozygotic twins was even stronger, at 0.17 (95% CI=0.10, 0.31). Within individuals, the odds ratio for drug abuse while pregnant compared with an equivalent prepregnancy interval was similar to that seen in pregnancy-discordant monozygotic twins, at 0.22 (95% CI=0.19, 0.26). Compared with cohabiting fathers, mothers had a greater reduction in risk for drug abuse during pregnancy (odds ratio=0.40, 95% CI=0.34, 0.47). Pregnancy was more protective in women with low parental education and without a cohabiting, actively drug-abusing father. Compared with prepregnancy baseline, within-individual analyses indicate that risk for drug abuse is also substantially reduced in the postpartum period, for example, the odds ratio for postpartum days 0-242 was 0.13 (95% CI=0.11, 0.16). Risk for drug abuse in women is substantially reduced during pregnancy. Multiple analyses suggest that this association is largely causal, suggesting that pregnancy is indeed a strong intrinsic motivator for drug abuse cessation. Similar strong protective effects may be present in the immediate postpartum period. Our results have implications for our etiologic models of drug abuse and especially for contingency management programs seeking to reduce drug abuse risk.

BACKGROUND Distracted driving attributable to the performance of secondary tasks is a major cause of motor vehicle crashes both among teenagers who are novice drivers and among adults who are experienced drivers. METHODS We conducted two studies on the relationship between the performance of secondary tasks, including cell-phone use, and the risk of crashes and near-crashes. To facilitate objective assessment, accelerometers, cameras, global positioning systems, and other sensors were installed in the vehicles of 42 newly licensed drivers (16.3 to 17.0 years of age) and 109 adults with more driving experience. RESULTS During the study periods, 167 crashes and near-crashes among novice drivers and 518 crashes and near-crashes among experienced drivers were identified. The risk of a crash or near-crash among novice drivers increased significantly if they were dialing a cell phone (odds ratio, 8.32; 95% confidence interval [CI], 2.83 to 24.42), reaching for a cell phone (odds ratio, 7.05; 95% CI, 2.64 to 18.83), sending or receiving text messages (odds ratio, 3.87; 95% CI, 1.62 to 9.25), reaching for an object other than a cell phone (odds ratio, 8.00; 95% CI, 3.67 to 17.50), looking at a roadside object (odds ratio, 3.90; 95% CI, 1.72 to 8.81), or eating (odds ratio, 2.99; 95% CI, 1.30 to 6.91). Among experienced drivers, dialing a cell phone was associated with a significantly increased risk of a crash or near-crash (odds ratio, 2.49; 95% CI, 1.38 to 4.54); the risk associated with texting or accessing the Internet was not assessed in this population. The prevalence of high-risk attention to secondary tasks increased over time among novice drivers but not among experienced drivers. CONCLUSIONS The risk of a crash or near-crash among novice drivers increased with the performance of many secondary tasks, including texting and dialing cell phones.

Women with angina pectoris and abnormal stress test findings commonly have no epicardial coronary artery disease (CAD) at catheterization. The aim of the present study was to develop a risk score to predict obstructive CAD in such patients. Data were analyzed from 337 consecutive women with angina pectoris and abnormal stress test findings who underwent cardiac catheterization at our center from 2003 to 2007. Forward selection multivariate logistic regression analysis was used to identify the independent predictors of CAD, defined by ≥50% diameter stenosis in ≥1 epicardial coronary artery. The independent predictors included age ≥55 years (odds ratio 2.3, 95% confidence interval 1.3 to 4.0), body mass index <30 kg/m(2) (odds ratio 1.9, 95% confidence interval 1.1 to 3.1), smoking (odds ratio 2.6, 95% confidence interval 1.4 to 4.8), low high-density lipoprotein cholesterol (odds ratio 2.9, 95% confidence interval 1.5 to 5.5), family history of premature CAD (odds ratio 2.4, 95% confidence interval 1.0 to 5.7), lateral abnormality on stress imaging (odds ratio 2.8, 95% confidence interval 1.5 to 5.5), and exercise capacity <5 metabolic equivalents (odds ratio 2.4, 95% confidence interval 1.1 to 5.6). Assigning each variable 1 point summed to constitute a risk score, a graded association between the score and prevalent CAD (ptrend <0.001). The risk score demonstrated good discrimination with a cross-validated c-statistic of 0.745 (95% confidence interval 0.70 to 0.79), and an optimized cutpoint of a score of ≤2 included 62% of the subjects and had a negative predictive value of 80%. In conclusion, a simple clinical risk score of 7 characteristics can help differentiate those more or less likely to have CAD among women with angina pectoris and abnormal stress test findings. This tool, if validated, could help to guide testing strategies in women with angina pectoris. Copyright © 2013 Elsevier Inc. All rights reserved.

Intravenous thrombolysis (IVT) is underutilized in ethnic minorities and women. To disentangle individual and system-based factors determining disparities in IVT use, we investigated race/sex differences in IVT utilization among hospitals serving varying proportions of minority patients. Ischemic stroke admissions were identified from the Nationwide Inpatient Sample between 2007 and 2011. Hospitals were categorized based on the percentage of minority patients admitted with stroke (<25% minority patients [white hospitals], 25% to 50% minority patients [mixed hospitals], or >50% minority patients [minority hospitals]). Logistic regression was used to evaluate the association between race/sex and IVT use within and between the different hospital strata. Among 337 201 stroke admissions, white men had the highest odds of IVT among all race/sex groups in any hospital strata, and the odds of IVT for white men did not differ by hospital strata. For white women and minority men, the odds of IVT were significantly lower in minority hospitals compared with white hospitals (odds ratio, 0.83; 95% confidence interval, 0.71-0.97, for white women; and odds ratio, 0.82; 95% confidence interval, 0.69-0.99, for minority men). Race disparities in IVT use among women were observed in white hospitals (odds ratio, 0.88; 95% confidence interval, 0.78-0.99, in minority compared with white women), but not in minority hospitals (odds ratio, 0.94, 95% confidence interval, 0.82-1.09). Sex disparities in IVT use were observed among whites but not among minorities. Minority men and white women have significantly lower odds of IVT in minority hospitals compared with white hospitals. IVT use in white men does not differ by hospital strata. © 2017 American Heart Association, Inc.

Substance use disorders are major contributors to excess mortality among individuals with attention deficit hyperactivity disorder (ADHD), yet associations between pharmacological ADHD treatment and substance-related problems remain unclear. This study investigated concurrent and long-term associations between ADHD medication treatment and substance-related events. The authors analyzed 2005-2014 commercial health care claims from 2,993,887 (47.2% female) adolescent and adult ADHD patients. Within-individual analyses compared the risk of substance-related events (i.e., emergency department visits related to substance use disorders) during months in which patients received prescribed stimulant medication or atomoxetine relative to the risk during months in which they did not. In adjusted within-individual comparisons, relative to periods in which patients did not receive ADHD medication, male patients had 35% lower odds of concurrent substance-related events when receiving medication (odds ratio=0.65, 95% CI=0.64-0.67), and female patients had 31% lower odds of concurrent substance-related events (odds ratio=0.69, 95% CI=0.67-0.71). Moreover, male patients had 19% lower odds of substance-related events 2 years after medication periods (odds ratio=0.81, 95% CI=0.78-0.85), and female patients had 14% lower odds of substance-related events 2 years after medication periods (odds ratio=0.86, 95% CI= 0.82-0.91). Sensitivity analyses supported most findings but were less consistent for long-term associations among women. These results provide evidence that receiving ADHD medication is unlikely to be associated with greater risk of substance-related problems in adolescence or adulthood. Rather, medication was associated with lower concurrent risk of substance-related events and, at least among men, lower long-term risk of future substance-related events.

Psychosocial factors such as marital status (odds ratio, 3.52; 95% confidence interval, 1.43-8.69; P = .006) and nonclinical factors such as outpatient nonattendances (odds ratio, 2.52; 95% confidence interval, 1.22-5.23; P = .013) and referrals made (odds ratio, 1.20; 95% confidence interval, 1.06-1.35; P = .003) predict hospital utilization for patients in a chronic disease management program. Along with optimizing patients' clinical condition by prescribed medical guidelines and supporting patient self-management, addressing psychosocial and nonclinical issues are important in attempting to avoid hospital utilization for people with chronic illnesses.

The presence of an articular cartilage lesion in anterior cruciate ligament-injured knees is considered a predictor of osteoarthritis. This study was undertaken to evaluate risk factors for full-thickness articular cartilage lesions in anterior cruciate ligament-injured knees, in particular the role of gender and the sport causing the initial injury. Cohort study (prognosis); Level of evidence, 2. Primary unilateral anterior cruciate ligament reconstructions prospectively registered in the Swedish and the Norwegian National Knee Ligament Registry during 2005 through 2008 were included (N = 15 783). Logistic regression analyses were used to evaluate risk factors for cartilage lesions. A total of 1012 patients (6.4%) had full-thickness cartilage lesions. The median time from injury to surgery was 9 months (range, 0 days-521 months). Male patients had an increased odds of full-thickness cartilage lesions compared with females (odds ratio = 1.22; 95% confidence interval, 1.04-1.42). In males, team handball had an increase in the odds of full-thickness cartilage lesions compared with soccer (odds ratio = 2.36; 95% confidence interval, 1.33-4.19). Among female patients, no sport investigated showed a significant decrease or increase in the odds of full-thickness cartilage lesions. The odds of a full-thickness cartilage lesion increased by 1.006 (95% confidence interval, 1.005-1.008) for each month elapsed from time of injury until anterior cruciate ligament reconstruction when all patients were considered, while time from injury to surgery did not affect the odds significantly in those patients reconstructed within 1 year of injury (odds ratio = 0.98; 95% confidence interval, 0.95-1.02). Previous surgery increased the odds of having a full-thickness cartilage lesion (odds ratio = 1.40; 95% confidence interval, 1.21-1.63). One year of increasing patient age also increased the odds (odds ratio = 1.05; 95% confidence interval, 1.05-1.06). Male gender is associated with an increased risk of full-thickness articular cartilage lesions in anterior cruciate ligament-injured knees. Male team handball players had an increased risk of full-thickness lesions. No other sports investigated were found to have significant effect on the risk in either gender. Furthermore, age, previous surgery, and time from injury to surgery exceeding 12 months are risk factors for full-thickness cartilage lesions.

Pharmacist prescription of hormonal contraception in Oregon: Baseline knowledge and interest in provision.

Oregon has implemented legislation expanding the scope of pharmacists to directly prescribe short-acting hormonal contraception (pill and patch) without a medical prescription. Pharmacists are crucial to the success of the new law, but relatively little is known about their intentions to prescribe contraception, or the motivators or barriers in providing this service. With the use of a cross-sectional survey of pharmacists practicing in Oregon before the legislative implementation, we analyzed responses to assess contraceptive knowledge, motivation to participate in direct provision, and perception of barriers to pharmacist prescription of contraception. A logistic regression model was used to examine the association between years in pharmacy practice and intention to provide direct access to contraception. A total of 509 pharmacists responded (17%). If training and reimbursement were offered, more than one-half of pharmacists would potentially be interested in prescribing contraception, managing side-effects, or moving women to a different hormonal method (57%, 61%, and 54%, respectively). However, only 39.1% of pharmacists surveyed planned to actually prescribe hormonal contraception when the legislation took effect. Shortage of pharmacy staff to provide services, concerns about liability, and a need for additional training were the three largest barriers to participation. Pharmacists practicing in urban locations (odds ratio 1.73, 95% CI 1.11-2.70) or currently offering emergency contraception (odds ratio 2.23, 95% CI 1.47-3.40) were significantly more likely to be planning to participate. Preliminary data indicate a need to support pharmacists with education on contraceptive provision and development of interventions to facilitate counseling in the pharmacy setting.

Tumor necrosis factor alpha (TNFα) gene -238G/A polymorphism (rs361525) is associated with psoriasis in several populations worldwide. To the best of our knowledge, there is no information about this polymorphism in Indian psoriatic patients. This study was undertaken to fill the gap in knowledge. This case-control study involved 72 patients with psoriasis vulgaris (PsV) and 72 age and gender matched healthy individuals. TNFα -238G/A polymorphism was genotyped by PCR-RFLP method. TNFα -238A allele was 5 times commoner in PsV patients than in the control group (P = 4.1 × 10 -7 ; odds ratio [OR] = 6.5 [0.95 CI: 2.9-14.6]). Distribution of the genotypes in the two groups showed statistically significant difference in dominant genetic model (P = 2.3 × 10 -7 ) and not in recessive genetic model (P = 2.5 × 10 -1 ). Odds ratio for the occurrence of -238A genotype in PsV patients was 8.8 (0.95 CI: 3.5-20.2). The association showed no major difference when PsV patients were subgrouped into type I and type II categories and tested separately. Subgroup analysis on the basis of disease severity showed higher association with the moderate-severe subgroup (P = 2.4 × 10 -9 , OR 15.4 [0.95 CI: 5.8-41.0]) than with mild subgroup (P = 1.3 × 10 -2 , OR 3.8 [0.95 CI: 1.3-10.9]).

This study assessed public awareness of warning symptoms, risk factors, and treatment of stroke in Ludhiana, Punjab, North West India. A hospital-based survey was conducted between February 2002 and September 2002 by the Stroke section of Christian Medical College. The study subjects were relatives of patients without history of stroke, attending the outpatient department of the hospital. Trained medical students, interns, and a nurse interviewed subjects using a structured, pretested, open-ended questionnaire. Nine hundred forty-two individuals were interviewed during the study period (56.4% men, mean age 40.1 years, age range 15 to 80 years). Forty-five percent of the subjects did not recognize the brain as the affected organ in stroke. In the multivariate analysis, higher education (P<0.001; odds ratio 2.6; 95%, CI 1.8 to 3.8) and upper socioeconomic status (P<0.005; odds ratio 1.6; CI, 1.1 to 2.2) correlated with a better knowledge of which organ was affected in stroke. Twenty-three percent of the participants did not know a single warning symptom of stroke. Twenty-one percent of the subjects could not identify even a single risk factor for stroke. Seven percent of the study population believed that oil massage would improve stroke victims. A small proportion of subjects believed in witchcraft, faith healing, homeopathic, and ayurvedic treatment (3%). This hospital-based survey reveals a better awareness of stroke warning signs and risk factors. However, knowledge regarding the organ involved, etiology, and treatment of stroke is lacking. Considerable education is needed to increase public awareness in modern concepts of stroke treatment.

To define the prevalence and the features of polycystic ovary syndrome (PCOS) in patients with psoriasis. To our knowledge, the association between PCOS and psoriasis has not been explored in previous studies. Psoriasis is linked with metabolic syndrome, insulin resistance, and non-alcoholic fatty liver disease, which are features often associated with PCOS. A cross-sectional analysis was performed between January 2010 and April 2012. Unit of human reproductive pathophysiology, Catholic University Hospital. We prospectively analyzed 51 patients with psoriasis and 102 healthy age- and body mass index (BMI)-matched controls. None. The prevalence and characteristics of PCOS women of reproductive age with chronic plaque psoriasis. The prevalence of PCOS was greater in patients with psoriasis than in matched control subjects (47.05% and 11.76%, respectively; odds ratio, 6.66; 95% confidence interval 2.95-15.07). Among the women with psoriasis, the prevalence of Psoriasis Area and Severity Index ≥10 was higher in patients with PCOS than in subjects without PCOS (odds ratio, 3.5; 95% confidence interval 1.04-11.72). The prevalence of PCOS in women with psoriasis is remarkably greater than in age- and BMI-matched control women. Copyright © 2013 American Society for Reproductive Medicine.

Identification of genetic variations related to high myopia may advance our knowledge of the etiopathogenesis of refractive error. This study investigated the role of potassium channel gene (KCNQ5) polymorphisms in high myopia. We performed a case-control study of 1563 unrelated Han Chinese subjects (809 cases of high myopia and 754 emmetropic controls). Five tag single-nucleotide polymorphisms (SNPs) of KCNQ5 were genotyped, and association testing with high myopia was conducted using logistic regression analysis adjusted for sex and age to give P asym values, and multiple comparisons were corrected by permutation test to give P emp values. All five noncoding SNPs were associated with high myopia. The SNP rs7744813, previously shown to be associated with refractive error and myopia in two GWAS, showed an odds ratio of 0.75 (95% CI 0.63-0.90; P emp = 0.0058) for the minor allele. The top SNP rs9342979 showed an odds ratio of 0.75 (95% CI 0.64-0.89; P emp = 0.0045) for the minor allele. Both SNPs are located within enhancer histone marks and DNase-hypersensitive sites. Our data support the involvement of KCNQ5 gene polymorphisms in the genetic susceptibility to high myopia and further exploration of KCNQ5 as a risk factor for high myopia.

Home visits during pregnancy: consequences on pregnancy outcome, use of health services, and women's situations.

Blondel, B; Bréart, G

1995-08-01

This review of eight randomized controlled trials assessed two different types of home visits during pregnancy: (1) those offering social support to high-risk women; and (2) those providing medical care to women with complications. In both categories, pregnancy outcome was not improved when women received home visits. The summary odds ratio for preterm delivery (< 37 weeks) was 1.0 (95% CI: 0.8 to 1.1). Nor did the home visits decrease the rate of hospital admission for women with complications (mainly threatened preterm labor or toxemia); the corresponding summary odds ratio was 0.9 (95% CI: 0.7 to 1.2). Nevertheless in some trials home visits had positive effects on women (medical knowledge, support levels, health habits, and satisfaction). The randomized controlled trials provide little evidence that programs offering home visits are effective in improving either pregnancy outcome or the use of health services. A better integration of hospital and home services might allow a more rational use of health services for women with complications. In addition, we need to define more precisely the content of home visits providing social support. For this, further research is required on how emotional support, health education, and advice influence the health of women and infants and mother-child interactions.

The objective of this study was to examine mental health conditions among hospitalized individuals with Parkinson's disease in the United States. This was a serial cross-sectional study of hospitalizations of individuals aged ≥60 identified in the Nationwide Inpatient Sample dataset from 2000 to 2010. We identified all hospitalizations with a diagnosis of PD, alcohol abuse, anxiety, bipolar disorder, depression, impulse control disorders, mania, psychosis, substance abuse, and attempted suicide/suicidal ideation. National estimates of each mental health condition were compared between hospitalized individuals with and without PD. Hierarchical logistic regression models determined which inpatient mental health diagnoses were associated with PD, adjusting for demographic, payer, geographic, and hospital characteristics. We identified 3,918,703 mental health and substance abuse hospitalizations. Of these, 2.8% (n = 104, 437) involved a person also diagnosed with PD. The majority of mental health and substance abuse patients were white (86.9% of PD vs 83.3% of non-PD). Women were more common than men in both groups (male:female prevalence ratio, PD: 0.78, 0.78-0.79, non-PD: 0.58, 0.57-0.58). Depression (adjusted odds ratio 1.32, 1.31-1.34), psychosis (adjusted odds ratio 1.25, 1.15-1.33), bipolar disorder (adjusted odds ratio 2.74, 2.69-2.79), impulse control disorders (adjusted odds ratio 1.51, 1.31-1.75), and mania (adjusted odds ratio 1.43, 1.18-1.74) were more likely among PD patients, alcohol abuse was less likely (adjusted odds ratio 0.26, 0.25-0.27). We found no PD-associated difference in suicide-related care. PD patients have unique patterns of acute care for mental health and substance abuse. Research is needed to guide PD treatment in individuals with pre-existing psychiatric illnesses, determine cross provider reliability of psychiatric diagnoses in PD patients, and inform efforts to improve psychiatric outcomes. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

Several epidemiologic studies have indicated an increased risk of lung cancer among welders. We used the SYNERGY project database to assess welding as a risk factor for developing lung cancer. The database includes data on 15,483 male lung cancer cases and 18,388 male controls from 16 studies in Europe, Canada, China, and New Zealand conducted between 1985 and 2010. Odds ratios and 95% confidence intervals between regular or occasional welding and lung cancer were estimated, with adjustment for smoking, age, study center, and employment in other occupations associated with lung cancer risk. Overall, 568 cases and 427 controls had ever worked as welders and had an odds ratio of developing lung cancer of 1.44 (95% confidence interval: 1.25, 1.67) with the odds ratio increasing for longer duration of welding. In never and light smokers, the odds ratio was 1.96 (95% confidence interval: 1.37, 2.79). The odds ratios were somewhat higher for squamous and small cell lung cancers than for adenocarcinoma. Another 1,994 cases and 1,930 controls had ever worked in occupations with occasional welding. Work in any of these occupations was associated with some elevation of risk, though not as much as observed in regular welders. Our findings lend further support to the hypothesis that welding is associated with an increased risk of lung cancer. PMID:24052544

Despite the recent flourishing of mediation analysis techniques, many modern approaches are difficult to implement or applicable to only a restricted range of regression models. This report provides practical guidance for implementing a new technique utilizing inverse odds ratio weighting (IORW) to estimate natural direct and indirect effects for mediation analyses. IORW takes advantage of the odds ratio's invariance property and condenses information on the odds ratio for the relationship between the exposure (treatment) and multiple mediators, conditional on covariates, by regressing exposure on mediators and covariates. The inverse of the covariate-adjusted exposure-mediator odds ratio association is used to weight the primary analytical regression of the outcome on treatment. The treatment coefficient in such a weighted regression estimates the natural direct effect of treatment on the outcome, and indirect effects are identified by subtracting direct effects from total effects. Weighting renders treatment and mediators independent, thereby deactivating indirect pathways of the mediators. This new mediation technique accommodates multiple discrete or continuous mediators. IORW is easily implemented and is appropriate for any standard regression model, including quantile regression and survival analysis. An empirical example is given using data from the Moving to Opportunity (1994–2002) experiment, testing whether neighborhood context mediated the effects of a housing voucher program on obesity.

The objective of this study was to determine the source of health care funding for heads of households related to the management of severe malaria in children admitted to a Kinshasa reference hospital. This cross-sectional study was conducted on 1,350 hospitalised children under the age of 15 years treated for severe malaria in Kinshasa reference hospitals from January to November 2011 and the heads of households of these children. Only 46% of heads of households reported having sufficient funds directly available in the household budget. The remaining 54% had to call upon external sources of funding (sale of assets, loans, pawning goods). The use of a loan tended to increase significantly mainly for households with a low (adjusted odds ratio = 6.2), and intermediate socioeconomic status (adjusted odds ratio = 3.8) and for households working in the informal sector (adjusted odds ratio = 2.5). Similarly, the sale of assets was more frequently reported for households working in the informal sector (adjusted odds ratio = 2.4) and for female heads of households (adjusted odds ratio = 3.9). The management of severe malaria is a burden on household income. The majority of heads of households concerned needs to use external funding sources. A State subsidy for this management would help to reduce the risk of debt and sale of assets, especially for the poorest households.

Purpose: Since March 2007, the Standing Committee on Vaccination (STIKO) recommends HPV vaccination for all 12–17 y-old females in Germany. In the absence of an immunization register, we aimed at assessing HPV-vaccination coverage and knowledge among students in Berlin, the largest city in Germany, to identify factors influencing HPV-vaccine uptake. Results: Between September and December 2010, 442 students completed the questionnaire (mean age 15.1; range 14–19). In total 281/442 (63.6%) students specified HPV correctly as a sexually transmitted infection. Of 238 participating girls, 161 (67.6%) provided their vaccination records. Among these, 66 (41.0%) had received the recommended three HPV-vaccine doses. Reasons for being HPV-unvaccinated were reported by 65 girls: Dissuasion from parents (40.2%), dissuasion from their physician (18.5%), and concerns about side-effects (30.8%) (multiple choices possible). The odds of being vaccinated increased with age (Odds Ratio (OR) 2.19, 95% Confidence Interval (CI) 1.16, 4.15) and decreased with negative attitude toward vaccinations (OR = 0.33, 95%CI 0.13, 0.84). Methods: Self-administered questionnaires were distributed to 10th grade school students in 14 participating schools in Berlin to assess socio-demographic characteristics, knowledge, and statements on vaccinations. Vaccination records were reviewed. Multivariable statistical methods were applied to identify independent predictors for HPV-vaccine uptake among female participants. Conclusions: HPV-vaccine uptake was low among school girls in Berlin. Both, physicians and parents were influential regarding their HPV-vaccination decision even though personal perceptions played an important role as well. School programs could be beneficial to improve knowledge related to HPV and vaccines, and to offer low-barrier access to HPV vaccination. PMID:22995838

To examine the association between knowledge of chemical exposure at work and cigarette smoking among Korean immigrant drycleaners. A cross-sectional survey was conducted with a total of 151 Korean immigrant drycleaners (mean age = 49 years, 64 % male) from 96 drycleaning shops in a Midwestern state. The data were collected on demographic and work-related characteristics, knowledge of occupational chemical exposure, health concerns associated with chemical exposure, and smoking status. Approximately 25 % of participants were current smokers. The multivariate regression showed that greater knowledge of occupational chemical exposures was significantly associated with a lower likelihood of current smoking [odds ratio (OR) .63; 95 % confidence interval (CI) .41-.95]. Furthermore, male gender (OR 6.32; 95 % CI 1.66-24.00), shorter-term residence in the US (OR .93; 95 % CI .88-.98), and having multiple duties (OR 2.76; 95 % CI 1.01-7.51) were important covariates associated with current smoking among Korean immigrant drycleaners. Knowledge on occupational chemical exposure was significantly associated with smoking among Korean immigrant drycleaners. Smoking cessation programs for this population should consider integrated approaches that incorporate work environment factors into individual and sociocultural components.

A questionnaire was applied on a sample of 86 persons from five health areas of the municipality. A descriptive analysis was made. Odds ratios were calculated to determine association between ways for obtaining information and knowledge on the existence of the disease, symptoms and transmission forms. the respondents know about tuberculosis as a disease, its symptoms, and its presence in Cuba, but the percentages corresponding to the truly significant symptoms are low, including incorrect identifications of towel, comb and mosquitoes as transmission ways of the disease. Television, radio and friends were the most mentioned sources of information. the population from Habana Vieja municipality knows about the existence of TB. However, specific knowledge about symptoms of the disease and ways of transmissions are insufficient. Changing this situation requires the strengthening of the role of the mass media role and the development of local communication strategies suited to local characteristics.

Epidemiologic studies suggest that greater consumption of fruit and vegetables may decrease the risk of diabetes mellitus, but the evidence is limited and inconclusive. Plasma vitamin C level is a good biomarker of fruit and vegetable intake, but, to our knowledge, no prospective studies have examined its association with diabetes risk. This study aims to examine whether fruit and vegetable intake and plasma vitamin C level are associated with the risk of incident type 2 diabetes. We administered a semiquantitative food frequency questionnaire to men and women from a population-based prospective cohort (European Prospective Investigation of Cancer-Norfolk) study who were aged 40 to 75 years at baseline (1993-1997) when plasma vitamin C level was determined and habitual intake of fruit and vegetables was assessed. During 12 years of follow-up between February 1993 and the end of December 2005, 735 clinically incident cases of diabetes were identified among 21 831 healthy individuals. We report the odds ratios of diabetes associated with sex-specific quintiles of fruit and vegetable intake and of plasma vitamin C levels. A strong inverse association was found between plasma vitamin C level and diabetes risk. The odds ratio of diabetes in the top quintile of plasma vitamin C was 0.38 (95% confidence interval, 0.28-0.52) in a model adjusted for demographic, lifestyle, and anthropometric variables. In a similarly adjusted model, the odds ratio of diabetes in the top quintile of fruit and vegetable consumption was 0.78 (95% confidence interval, 0.60-1.00). Higher plasma vitamin C level and, to a lesser degree, fruit and vegetable intake were associated with a substantially decreased risk of diabetes. Our findings highlight a potentially important public health message on the benefits of a diet rich in fruit and vegetables for the prevention of diabetes.

Triage is the act of stratifying the need for medical attention. Effective triage must account for injury patterns and severity. Personnel making triage decisions must also consider the patients' physiologic states. Vital signs can possibly be used to assess for the presence of physiological derangements such as coagulopathy, acidosis, or a significant base deficit. Providers could use this knowledge to assist with triage at casualty collection points where laboratory studies or point of care testing may not be available. With institutional approval, data were extracted from the Joint Theater Trauma Registry for all patients with thoracic trauma between 2002 and 2012. Patients were identified by International Statistical Classification of Diseases and Related Health Problems, 9th Revision (ICD-9) codes. Heart rate (HR), systolic blood pressure (SBP), and pulse pressure were correlated with coagulopathy (international normalization ratio ≥ 1.5), acidosis (pH < 7.2) or an elevated base deficit (>6) on admission. Sensitivity, specificity, positive predictive values, negative predictive values, and odds ratios were calculated. HR > 100, SBP < 90, or pulse pressure <30 were associated with an increased risk for acidosis (odds ratio 3.06 [95% confidence interval 2.48-3.78], 4.72 [3.85-5.78], and 2.73 [2.15-3.48], respectively), coagulopathy (2.21 [1.72-2.83], 4.55 [3.57-5.80], and 2.73 [2.15-3.48], respectively), and base deficit >6 (2.17 [1.88-2.50], 3.48 [2.87-4.22], and 2.22 [1.78-2.77], respectively). HR was a moderately sensitive marker (0.74), whereas SBP was a specific marker (0.93). SBP < 90 is an effective marker for ruling in physiologic derangement after thoracic trauma. HR > 100 was associated with over twice the odds for physiologic derangement. Vital signs can be used to assess for physiologic derangement in the population studied and may help in triage.

Physicians must pass the United States Medical Licensing Examination (USMLE) to obtain an unrestricted license to practice allopathic medicine in the United States. Little is known, however, about how well USMLE performance relates to physician behavior in practice, particularly conduct inconsistent with safe, effective patient care. The authors examined the extent to which USMLE scores relate to the odds of receiving a disciplinary action from a U.S. state medical board. Controlling for multiple factors, the authors used non-nested multilevel logistic regression analyses to estimate the relationships between scores and receiving an action. The sample included 164,725 physicians who graduated from U.S. MD-granting medical schools between 1994 and 2006. Physicians had a mean Step 1 score of 214 (standard deviation [SD] = 21) and a mean Step 2 Clinical Knowledge (CK) score of 213 (SD = 23). Of the physicians, 2,205 (1.3%) received at least one action. Physicians with higher Step 2 CK scores had lower odds of receiving an action. A 1-SD increase in Step 2 CK scores corresponded to a decrease in the chance of disciplinary action by roughly 25% (odds ratio = 0.75; 95% CI = 0.70-0.80). After accounting for Step 2 CK scores, Step 1 scores were unrelated to the odds of receiving an action. USMLE Step 2 CK scores provide useful information about the odds a physician will receive an official sanction for problematic practice behavior. These results provide validity evidence supporting current interpretation and use of Step 2 CK scores.

The secondary sex ratio is the ratio of male to female live births and historically has ranged from 102 to 106 males to 100 females. Temporal declines have been reported in many countries prompting authors to hypothesize an environmental etiology. Blood specimens were obtained from 99 women aged 24-34 prior to attempting pregnancy and quantified for 76 polychlorinated biphenyl (PCB) congeners using dual column gas chromatography with electron capture detection. Women were prospectively followed until pregnancy or 12 cycles of trying. The odds of a male birth for three PCB groupings (total, estrogenic, anti-estrogenic) controlling for maternal characteristics were estimatedmore » using logistic regression. Among the 50 women with live births and PCB data, 26 female and 24 male infants were born (ratio 0.92). After adjusting for age and body mass index, odds of a male birth were elevated among women in the second (OR=1.29) and third (OR=1.48) tertiles of estrogenic PCBs; odds (OR=0.70) were reduced among women in the highest tertile of anti-estrogenic PCBs. All confidence intervals included one. The direction of the odds ratios in this preliminary study varied by PCB groupings, supporting the need to study specific PCB patterns when assessing environmental influences on the secondary sex ratio.« less

Maternal vitamin status contributes to clinical spontaneous abortion, but the role of B-vitamin and homocysteine status in subclinical early pregnancy loss is unknown. Three-hundred sixty-four textile workers from Anqing, China, who conceived at least once during prospective observation (1996-1998), provided daily urine specimens for up to 1 year, and urinary human chorionic gonadotropin was assayed to detect conception and early pregnancy loss. Homocysteine, folate, and vitamins B6 and B12 were measured in preconception plasma. Relative to women in the lowest quartile of vitamin B6, those in the third and fourth quartiles had higher adjusted proportional hazard ratios of conception (hazard ratio (HR)=2.2, 95% confidence interval (CI): 1.3, 3.4; HR=1.6, 95% CI: 1.1, 2.3, respectively), and the adjusted odds ratio for early pregnancy loss in conceptive cycles was lower in the fourth quartile (odds ratio=0.5, 95% CI: 0.3, 1.0). Women with sufficient vitamin B6 had a higher adjusted hazard ratio of conception (HR=1.4, 95% CI: 1.1, 1.9) and a lower adjusted odds ratio of early pregnancy loss in conceptive cycles (odds ratio=0.7, 95% CI: 0.4, 1.1) than did women with vitamin B6 deficiency. Poor vitamin B6 status appears to decrease the probability of conception and to contribute to the risk of early pregnancy loss in this population.

Objective knowledge was assessed with 24 questions regarding HIV/AIDS, and subjective knowledge with the question "how much do you think you know about HIV/AIDS?" The variables associated with condom use were identified using logistic regression analysis and by calculating odds ratios with a 95% confidence interval. The degree of objective knowledge was "average", differentiated by socioeconomic strata (p < 0.001), and was higher in adolescents from medium and high socioeconomic strata (p < 0.008). Regarding subjective knowledge, adolescents from the low, medium, and high socioeconomic strata claimed to know "a little", and the ones from the lowest stratum claimed to know "very little". Condom use was higher in males (35.4%), and in adolescents from high socioeconomic strata (p < 0.005), than in females (15.3%) (p < 0.001). Although there was a correlation between objective and subjective knowledge (r = 0.37, p < 0.001), a higher degree of subjective knowledge was associated with condom use (p < 0.001). Subjective knowledge, belonging to medium and high socioeconomic strata and being male, were predictors of condom use.

This study examines in a cross-sectional study 'the tobacco control environment' including tobacco policy implementation and its association with quit ratio. 545 communities from 17 high-income, upper-middle, low-middle and low-income countries (HIC, UMIC, LMIC, LIC) involved in the Environmental Profile of a Community's Health (EPOCH) study from 2009 to 2014. Community audits and surveys of adults (35-70 years, n=12 953). Summary scores of tobacco policy implementation (cost and availability of cigarettes, tobacco advertising, antismoking signage), social unacceptability and knowledge were associated with quit ratios (former vs ever smokers) using multilevel logistic regression models. Average tobacco control policy score was greater in communities from HIC. Overall 56.1% (306/545) of communities had >2 outlets selling cigarettes and in 28.6% (154/539) there was access to cheap cigarettes (<5cents/cigarette) (3.2% (3/93) in HIC, 0% UMIC, 52.6% (90/171) LMIC and 40.4% (61/151) in LIC). Effective bans (no tobacco advertisements) were in 63.0% (341/541) of communities (81.7% HIC, 52.8% UMIC, 65.1% LMIC and 57.6% LIC). In 70.4% (379/538) of communities, >80% of participants disapproved youth smoking (95.7% HIC, 57.6% UMIC, 76.3% LMIC and 58.9% LIC). The average knowledge score was >80% in 48.4% of communities (94.6% HIC, 53.6% UMIC, 31.8% LMIC and 35.1% LIC). Summary scores of policy implementation, social unacceptability and knowledge were positively and significantly associated with quit ratio and the associations varied by gender, for example, communities in the highest quintile of the combined scores had 5.0 times the quit ratio in men (Odds ratio (OR) 5·0, 95% CI 3.4 to 7.4) and 4.1 times the quit ratio in women (OR 4.1, 95% CI 2.4 to 7.1). This study suggests that more focus is needed on ensuring the tobacco control policy is actually implemented, particularly in LMICs. The gender-related differences in associations of policy, social unacceptability and knowledge suggest that different strategies to promoting quitting may need to be implemented in men compared to women.

The Evaluation of Nitrous Oxide in the Gas Mixture for Anaesthesia (ENIGMA)-II trial randomly assigned 7,112 noncardiac surgery patients at risk of perioperative cardiovascular events to 70% N2O or 70% N2 groups. The aim of this follow-up study was to determine the effect of nitrous oxide on a composite primary outcome of death and major cardiovascular events at 1 yr after surgery. One-year follow-up was conducted via a medical record review and telephone interview. Disability was defined as a Katz index of independence in activities of daily living score less than 8. Adjusted odds ratios and hazard ratios were calculated as appropriate for primary and secondary outcomes. Among 5,844 patients evaluated at 1 yr, 435 (7.4%) had died, 206 (3.5%) had disability, 514 (8.8%) had a fatal or nonfatal myocardial infarction, and 111 (1.9%) had a fatal or nonfatal stroke during the 1-yr follow-up period. Exposure to nitrous oxide did not increase the risk of the primary outcome (odds ratio, 1.08; 95% CI, 0.94 to 1.25; P = 0.27), disability or death (odds ratio, 1.07; 95% CI, 0.90 to 1.27; P = 0.44), death (hazard ratio, 1.17; 95% CI, 0.97 to 1.43; P = 0.10), myocardial infarction (odds ratio, 0.97; 95% CI, 0.81 to 1.17; P = 0.78), or stroke (odds ratio, 1.08; 95% CI, 0.74 to 1.58; P = 0.70). These results support the long-term safety of nitrous oxide administration in noncardiac surgical patients with known or suspected cardiovascular disease.

There are limited data on factors associated with retention in Option B+. We sought to explore the characteristics of women retained in Option B+ in Malawi, with a focus on the role of HIV disclosure, awareness of partner HIV status, and knowledge around the importance of Option B+ for maternal-child health. Methods We performed a case-control study of HIV-infected women in Malawi initiated on antiretroviral therapy (ART) under Option B+. Cases were enrolled if they met criteria for default from Option B+ (out of ART for >60 days), and controls were enrolled in approximately 3:1 ratio if they were retained in care for at least 12 months. We surveyed socio-demographic characteristics, HIV disclosure and awareness of partner HIV status, self-report about receiving pre-ART education, and knowledge of Option B+. Univariate logistic regression was performed to determine factors associated with retention. Multivariate logistic regression model was used to evaluate the relationship between HIV disclosure, Option B+ knowledge, and retention after adjusting for age, schooling, and travel time to clinic. We enrolled 50 cases and 153 controls. Median age was 30 years (interquartile range (IQR) 25-34), and the majority (82%) initiated ART during pregnancy at a median gestational age of 24 weeks (IQR 16-28). Ninety-one per cent of the cases (39/43) who started ART during pregnancy defaulted by three months postpartum. HIV disclosure to the primary sex partner was more common among women retained in care (100% versus 78%, p  < 0.001). Odds of retention were significantly higher among women with: age >25 years (odds ratio (OR) 2.44), completion of primary school (OR 3.06), awareness of partner HIV status (OR 5.20), pre-ART education (OR 6.17), higher number of correct answers to Option B+ knowledge questions (OR 1.82), and support while taking ART (OR 3.65). Pre-ART education and knowledge were significantly correlated ( r  = 0.43, p  < 0.001). In multivariate analysis, awareness of partner HIV status (OR 4.07, 95% confidence interval (CI) 1.51-10.94, p  = 0.02) and Option B+ knowledge (OR 1.60, 95% CI 1.15-2.23, p  = 0.004) remained associated with retention. Interventions that address partner disclosure and strengthen pre-ART education around the benefits of ART for maternal and child health should be evaluated to improve retention in Malawi's Option B+ programme.

In 2010 the Salt Lake Valley Health Department conducted a pilot of an announced inspection program utilizing a randomized assignment of restaurants to an intervention group with announced inspections and a control group that remained on the usual schedule of unannounced inspections. After adjusting for food type, visible kitchen, outside quality assurance, season, and standardized inspector, significant reductions were found in the odds ratios of personal hygiene (adjusted odds ratios [aOR] = 0.11, p = .00) and equipment cleanliness (aOR = 0.19, p = .00) violations. In the models for the control group, none of the odds ratios were statistically different from one, indicating no change in the postintervention time period as compared to the preintervention period.

Anesthesiologists can provide psychometrically reliable daily evaluations of certified registered nurse anesthetist (CRNA) work habits for purposes of the mandatory ongoing professional practice evaluation (OPPE). Our goal was to evaluate the validity of assessing CRNA work habits. Observational study. Large teaching hospital. N=77 anesthesiologists evaluated work habits of N=67 CRNAs. The non-technical attribute of work habits was measured on a 6-item scale (e.g., 1="Only assumed responsibility when forced to, and failed to follow through consistently" versus 5="Consistently identified tasks and completed them efficiently and thoroughly"). One year of scores were used to assess validity. Each daily evaluation could also be accompanied by a written comment. Content analysis of comments was performed using two years of data. Statistical analyses were performed using mixed effects logistic regression, treating each anesthesiologist as a fixed effect to compensate for the leniency of their ratings. The N=77 anesthesiologists' response rate was 97.3%, obtained at a mean 2.93days after the request. The internal consistency of the scale was large: Cronbach's alpha 0.952. Controlling the false discovery rate at 5.0%, among the 67 CRNAs, 8 were significantly below average (each P≤0.0048) and 6 were above average (each P≤0.0018). During the 6months after CRNAs knew that their work habits scores would be used for OPPE, there were significant increases in the scores compared with the preceding 6months (odds ratio 1.93, P<0.0001). Greater CRNA's qualitative annual evaluation scores made by the chief CRNA, without knowledge of the work habit scores or comments, were associated with greater odds of the CRNA's leniency-adjusted work habit scores equaling 5.00 (odds ratio 1.53, P=0.0004). Comments of negative sentiment made by the anesthesiologists were associated with greater odds of the leniency-adjusted work habit scores being <5.00 (odds ratio 54.5, P<0.0001). Even though the anesthesiologists were already providing information about work habits using the work habits scale, approximately half the comments of negative sentiment included the theme of work habits (92/153, 60.1%). Reporting OPPE metrics are mandatory for the maintenance of clinical privileges of anesthesia practitioners in the USA. Basing such peer review on work habits can be quantitative, psychometrically reliable, and valid. Copyright © 2017 Elsevier Inc. All rights reserved.

To describe pregnancy complications, mode of delivery and neonatal outcomes by mother's residence. Register-based cohort study. Geographical regions of Iceland. Live singleton births from 1 January 2000 to 31 December 2009 (n = 40 982) and stillbirths ≥22 weeks or weighing ≥500 g (n = 145). Logistic regression was used to explore differences in outcomes by area of residence while controlling for potential confounders. Maternal residence was classified according to distance from Capital Area and availability of local health services. Preterm birth, low birthweight, perinatal death, gestational diabetes and hypertension. Of the 40 982 infants of the study population 26 255 (64.1%) were born to mothers residing in the Capital Area and 14 727 (35.9%) to mothers living outside the Capital Area. Infants outside the Capital Area were more likely to have been delivered by cesarean section (adjusted odds ratio 1.28; 95% CI 1.21-1.36). A lower prevalence of gestational diabetes (adjusted odds ratio 0.68; 95% CI 0.59-0.78), hypertension (adjusted odds ratio 0.82; 95% CI 0.71-0.94) as well as congenital malformations (adjusted odds ratio 0.55; 95% CI 0.48-0.63) was observed outside the Capital Area. We observed neither differences in mean birthweight, gestation length nor rate of preterm birth or low birthweight across Capital Area and non-Capital Area. The odds of perinatal deaths were significantly higher (adjusted odds ratio 1.87; 95% CI 1.18-2.95) outside the Capital Area in the second half of the study period. Lower prevalence of gestational diabetes and hypertension outside the Capital Area may be an indication of underreporting and/or lower diagnostic activity. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

HIV infection impacts heavily on the infected individual's overall health status. To determine significant health, lifestyle (smoking and alcohol use) and independent clinical manifestations associated with HIV status in rural and urban communities. Adults aged between 25 and 64 years completed a questionnaire in a structured interview with each participant. Blood specimens were analysed in an accredited laboratory using standard techniques and controls. Anthropometric measurements were determined using standardised methods. Of the 567 rural participants, 97 (17.1%) were HIV-infected, and 172 (40.6%) of the 424 urban participants. More than half of HIV-infected rural participants used alcohol and more than 40% smoked. Median body mass index (BMI) of HIV-infected participants was lower than that of uninfected participants. Significantly more HIV-infected participants reported experiencing cough (rural), skin rash (urban), diarrhoea (rural and urban), vomiting (rural), loss of appetite (urban) and involuntary weight loss (rural). Significantly more HIV-uninfected participants reported diabetes mellitus (urban) and high blood pressure (rural and urban). In rural areas, HIV infection was positively associated with losing weight involuntarily (odds ratio 1.86), ever being diagnosed with tuberculosis (TB) (odds ratio 2.50) and being on TB treatment (odds ratio 3.29). In the urban sample, HIV infection was positively associated with having diarrhoea (odds ratio 2.04) and ever being diagnosed with TB (odds ratio 2.49). Involuntary weight loss and diarrhoea were most likely to predict the presence of HIV. In addition, present or past diagnosis of TB increased the odds of being HIV-infected. Information related to diarrhoea, weight loss and TB is easy to obtain from patients and should prompt healthcare workers to screen for HIV.

A lifestyle cardiovascular risk score (LCRS) and a genetic risk score (GRS) have been independently associated with myocardial infarction (MI) in Hispanics/Latinos. Interaction or joint association between these scores has not been examined. Thus, our aim was to assess interactive and joint associations between LCRS and GRS, and each individual lifestyle risk factor, on likelihood of MI. Data included 1534 Costa Rican adults with nonfatal acute MI and 1534 matched controls. The LCRS used estimated coefficients as weights for each factor: unhealthy diet, physical inactivity, smoking, elevated waist:hip ratio, low/high alcohol intake, low socioeconomic status. The GRS included 14 MI-associated risk alleles. Conditional logistic regressions were used to calculate adjusted odds ratios. The odds ratios for MI were 2.72 (2.33, 3.17) per LCRS unit and 1.13 (95% CI 1.06, 1.21) per GRS unit. A significant joint association for highest GRS tertile and highest LCRS tertile and odds of MI was detected (odds ratio=5.43 [3.71, 7.94]; P<1.00×10 -7 ), compared to both lowest tertiles. The odds ratios were 1.74 (1.22, 2.49) under optimal lifestyle and unfavorable genetic profile, and 5.02 (3.46, 7.29) under unhealthy lifestyle but advantageous genetic profile. Significant joint associations were observed for the highest GRS tertile and the highest of each lifestyle component risk category. The interaction term was nonsignificant (P=0.33). Lifestyle risk factors and genetics are jointly associated with higher odds of MI among Hispanics/Latinos. Individual and combined lifestyle risk factors showed stronger associations. Efforts to improve lifestyle behaviors could help prevent MI regardless of genetic susceptibility. © 2016 The Authors.

Unfavorable work characteristics, such as low job control and too high or too low job demands, have been suggested to increase the likelihood of physical inactivity during leisure time, but this has not been verified in large-scale studies. The authors combined individual-level data from 14 European cohort studies (baseline years from 1985-1988 to 2006-2008) to examine the association between unfavorable work characteristics and leisure-time physical inactivity in a total of 170,162 employees (50% women; mean age, 43.5 years). Of these employees, 56,735 were reexamined after 2-9 years. In cross-sectional analyses, the odds for physical inactivity were 26% higher (odds ratio = 1.26, 95% confidence interval: 1.15, 1.38) for employees with high-strain jobs (low control/high demands) and 21% higher (odds ratio = 1.21, 95% confidence interval: 1.11, 1.31) for those with passive jobs (low control/low demands) compared with employees in low-strain jobs (high control/low demands). In prospective analyses restricted to physically active participants, the odds of becoming physically inactive during follow-up were 21% and 20% higher for those with high-strain (odds ratio = 1.21, 95% confidence interval: 1.11, 1.32) and passive (odds ratio = 1.20, 95% confidence interval: 1.11, 1.30) jobs at baseline. These data suggest that unfavorable work characteristics may have a spillover effect on leisure-time physical activity.

Background In urban Maharashtra, India, approximately half of mothers exclusively breastfeed. For children residing in informal settlements of Mumbai, this study examines factors associated with exclusive breastfeeding, and whether exclusive breastfeeding, in a community-based nutrition program to prevent and treat wasting among children under age three, is associated with enrolment during the mother’s pregnancy. Methods The nutrition program conducted a cross-sectional endline survey (October-December 2015) of caregivers in intervention areas. Factors associated with exclusive breastfeeding for infants under six months of age were explored using multi-level logistic regressions. Additionally, program surveillance data collected during home-based counselling visits documented breastfeeding practices for children under six months of age. Using the surveillance data (January 2014-March 2016), exclusive breastfeeding status was regressed adjusting for child, maternal and socioeconomic characteristics, and whether the child was enrolled in the program in utero or after birth. Results The community-based endline survey included 888 mothers of infants. Mothers who received the nutrition program home visits or attended group counselling sessions were more likely to exclusively breastfeed (adjusted odds ratio 1.67, 95% CI 1.16, 2.41). Having a normal weight-for-height z-score (adjusted odds ratio 1.57, 95% CI 1.00, 2.45) was associated positively with exclusive breastfeeding. As expected, being an older infant aged three to five months (adjusted odds ratio 0.34, 95% CI 0.25, 0.48) and receiving a prelacteal feed after birth (adjusted odds ratio 0.57, 95% CI 0.41, 0.80) were associated with lower odds of exclusively breastfeeding. Surveillance data (N = 3420) indicate that infants enrolled in utero have significantly higher odds of being exclusively breastfed (adjusted odds ratio 1.55, 95% CI 1.30, 1.84) than infants enrolled after birth. Conclusions Prenatal enrolment in community-based programs working on child nutrition in urban informal settlements of India can improve exclusive breastfeeding practices. PMID:29621355

Mothers who received the nutrition program home visits or attended group counselling sessions were more likely to exclusively breastfeed (adjusted odds ratio 1.67, 95% CI 1.16, 2.41). Having a normal weight-for-height z-score (adjusted odds ratio 1.57, 95% CI 1.00, 2.45) was associated positively with exclusive breastfeeding. As expected, being an older infant aged three to five months (adjusted odds ratio 0.34, 95% CI 0.25, 0.48) and receiving a prelacteal feed after birth (adjusted odds ratio 0.57, 95% CI 0.41, 0.80) were associated with lower odds of exclusively breastfeeding. Surveillance data (N = 3420) indicate that infants enrolled in utero have significantly higher odds of being exclusively breastfed (adjusted odds ratio 1.55, 95% CI 1.30, 1.84) than infants enrolled after birth. Prenatal enrolment in community-based programs working on child nutrition in urban informal settlements of India can improve exclusive breastfeeding practices.

Type 2 diabetes has an underlying pathology with thyroid dysfunction. However, few studies have investigated the association between thyroid hormones and diabetic peripheral neuropathy. Our aim was to evaluate the relationship between thyroid hormones and electrophysiological properties of peripheral nerves in type 2 diabetes. The medical records of 308 patients with type 2 diabetes were enrolled in this study. Subjects stratified by sex were divided into subgroups based on the diagnosis of nerve conduction study. The nerve conduction parameters were separately described with the spectrum of thyroid hormones. Multivariate regression models to analyze the potential links between thyroid hormones and nerve conduction parameters. The serum free triiodine thyronine levels between normal and abnormal nerve conduction groups were statistically different in total (4.55±0.65 vs 4.37±0.63, P<0.05) and female diabetic patients (4.46±0.50 vs 4.14±0.57, P<0.01). Moreover, the summed amplitude and velocity Z score of female and male increased with free triiodine thyronine levels (P<0.05). Sex-specific binary logistic regression models showed that free triiodine thyronine levels were associated with decreased odds of abnormal nerve conduction diagnosis (odds ratio [95%CI]=0.151[0.047-0.186]) and low tertile of summed amplitude Z score (odds ratio [95%CI]=0.283[0.099-0.809]) in female. In total patients, free triiodine thyronine level was negatively associated with odds of abnormal nerve conduction (odds ratio [95%CI]=0.436 [0.226-0.842]), low tertile of summed velocity (odds ratio [95%CI]=0.44[0.226-0.858]) and amplitude (odds ratio [95%CI]=0.436[0.227-0.838) Z score. Serum free triiodine thyronine level is associated with nerve conduction in diabetes. Low free triiodine thyronine may be a potential risk for diabetic peripheral neuropathy. © Georg Thieme Verlag KG Stuttgart · New York.

To identify and evaluate cranial magnetic resonance imaging findings associated with Ménière's disease. Seventy-eight patients with a documented diagnosis of Ménière's disease and 35 controls underwent 1.5 T or 3 T magnetic resonance imaging of the brain. Patients also underwent otological, vestibular and audiometric examinations. Lack of visualisation of the left and right vestibular aqueducts was identified as statistically significant amongst Ménière's disease patients (left, p = 0.0001, odds ratio = 0.02; right, p = 0.0004, odds ratio = 0.03). Both vestibular aqueducts were of abnormal size in the Ménière's disease group, albeit with left-sided significance (left, p = 0.008, odds ratio = 10.91; right, p = 0.49, odds ratio = 2.47). Lack of vestibular aqueduct visualisation on magnetic resonance imaging was statistically significant in Ménière's disease patients compared to the general population. The study findings suggest that magnetic resonance imaging can be useful to rule out retrocochlear pathology and provide radiological data to support the clinical diagnosis of Ménière's disease.

Bivariate categorical data analysis using normal linear conditional multinomial probability model.

Bivariate multinomial data such as the left and right eyes retinopathy status data are analyzed either by using a joint bivariate probability model or by exploiting certain odds ratio-based association models. However, the joint bivariate probability model yields marginal probabilities, which are complicated functions of marginal and association parameters for both variables, and the odds ratio-based association model treats the odds ratios involved in the joint probabilities as 'working' parameters, which are consequently estimated through certain arbitrary 'working' regression models. Also, this later odds ratio-based model does not provide any easy interpretations of the correlations between two categorical variables. On the basis of pre-specified marginal probabilities, in this paper, we develop a bivariate normal type linear conditional multinomial probability model to understand the correlations between two categorical variables. The parameters involved in the model are consistently estimated using the optimal likelihood and generalized quasi-likelihood approaches. The proposed model and the inferences are illustrated through an intensive simulation study as well as an analysis of the well-known Wisconsin Diabetic Retinopathy status data.

Abstract: Background: This study systematically reviewed the literature in order to determine the effect of Attention-Deficit Hyperactivity Disorder (ADHD) on injuries and assessed the magnitude of the potential association. Methods: A systematic review of the studies examining the association of ADHD and injuries was carried out across multiple databases. Odds ratios and standardized mean differences were pooled. Results: A total of 35 studies were selected for quantitative analysis. The association of ADHD and injuries was confirmed over the meta-analysis of eligible studies. The odds ratio pooled over all comparative studies was 1.96(95% CI: 1.6-2.4) using random effects model. Pooled odds ratio of 2.1 and 2.17 were calculated respectively when cohort and case-control studies or just cohort studies were included. The pooled odds ratio reduced to 1.8(CI:1.45-2.3) when studies on specific injuries were removed. For studies comparing scores of rating scales, the pooled standardized mean difference was 0.61(95% CI: 0.03-1.2). Conclusions: Those with ADHD are nearly two times more likely to be injured.

The crossover design can be of use to save the number of patients or improve power of a parallel groups design in studying treatments to noncurable chronic diseases. We propose using the generalized odds ratio for paired sample data to measure the relative effects in ordinal data between treatments and between periods. We show that one can apply the commonly used asymptotic and exact test procedures for stratified analysis in epidemiology to test non-equality of treatments in ordinal data, as well as obtain asymptotic and exact interval estimators for the generalized odds ratio under a three-period crossover design. We further show that one can apply procedures for testing the homogeneity of the odds ratio under stratified sampling to examine whether there are treatment-by-period interactions. We use the data taken from a three-period crossover trial studying the effects of low and high doses of an analgesic versus a placebo for the relief of pain in primary dysmenorrhea to illustrate the use of these test procedures and estimators proposed here.

The purpose of this study was to assess the safety of the use of selective serotonin reuptake inhibitors in pregnancy. We carried out a retrospective cohort study of 972 pregnant women who had been given at least 1 selective serotonin reuptake inhibitor prescription in the year before delivery and 3878 pregnant women who did not receive selective serotonin reuptake inhibitors and who were matched by the year of the infant's birth, the type of institute at birth, and the mother's postal code from 1990 to 2000 in the Canadian province of Saskatchewan. The risks of low birth weight (adjusted odds ratio, 1.58; 95% CI, 1.19, 2.11), preterm birth (adjusted odds ratio, 1.57; 95% CI, 1.28, 1.92), fetal death (adjusted odds ratio, 2.23; 95% CI, 1.01, 4.93), and seizures (adjusted odds ratio, 3.87; 95% CI, 1.00, 14.99) were increased in infants who were born to mothers who had received selective serotonin reuptake inhibitor therapy. The use of selective serotonin reuptake inhibitors in pregnancy may increase the risks of low birth weight, preterm birth, fetal death, and seizures.

To investigate the association between the three most common single nucleotide polymorphisms of the N-acetyltransferase 2 gene together with cigarette smoking and the risk of developing bladder cancer and its aggressiveness. A case-control study on 102 bladder cancer patients and 140 control subjects was conducted. The genomic DNA was extracted from peripheral white blood cells and N-acetyltransferase 2 alleles were differentiated by polymerase chain reaction-based restriction fragment length polymorphism methods. Bladder cancer risk was estimated as odds ratio and 95% confidence interval using binary logistic regression models adjusting for age and gender. Overall, N-acetyltransferase 2 slow genotypes were associated with bladder cancer risk (odds ratio=4.45; 95% confidence interval=2.26-8.77). The cigarette smokers with slow genotypes were found to have a sixfold increased risk to develop bladder cancer (odds ratio=6.05; 95% confidence interval=2.23-15.82). Patients with slow acetylating genotypes were more prone to develop high-grade (odds ratio=6.63; 95% confidence interval=1.15-38.13; P<0.05) and invasive (odds ratio=10.6; 95% confidence interval=1.00-111.5; P=0.05) tumor. N-acetyltransferase 2 slow genotype together with tobacco smoking increases bladder cancer risk. Patients with N-acetyltransferase 2 slow genotypes were more likely to develop a high-grade and invasive tumor. N-acetyltransferase 2 slow genotype is an important genetic determinant for bladder cancer in Bangladesh population. © 2014 Wiley Publishing Asia Pty Ltd.

We evaluated the association between meteorological conditions and sports deaths at elementary, junior high and senior high schools. Data were collected from attached documents such as accident reports and death certificate records in the National Agency for the Advancement of Sports and Health in Japan. Evaluation of seasonal variation showed a significant concentration of deaths from heat disorders and drowning in July and August. When heart disease was evaluated according to the sports situation, significant seasonal variation with a high number of deaths in September December was observed in sports events. Concerning circadian variation, deaths from heart disease showed a high peak at 10:00 11:00 a.m. in physical education classes and sports events, and at 2:00 5:00 p.m. in sports club activities. Analysis using a multiple logistic model showed a significantly lower odds ratio from heart disease and a significantly higher odds ratio from heat disorders at a wet bulb globe temperature of ≥21.0°C than at <21.0°C. According to the sports situation in heart disease, the odds ratio in sports club activities was significantly lower on days with rainfall than on days without rainfall. According to the school categories in heart diseases, the odds ratio in girls in elementary school was significantly higher than that in boys, but the odds ratio in girls in senior high school was significantly lower than that in boys.

Occupational stress has become a major cause of illness and a major risk to the psychological and social well-being of workers. In this context, the aim of this study was to estimate the prevalence of occupational stress in employees of a banking network in the municipal region of Vitória, state of Espírito Santo, and its association with sociodemographic variables and work characteristics. This cross-sectional study involved 525 bank employees. Occupational stress was evaluated using the short version of the Job Stress Scale. A multivariate analysis was conducted to evaluate the association between the Karasek quadrants and the independent variables. It was found that most bank employees belonged to the "passive jobs" quadrant (34.4%, n = 179) and were considered to have an intermediate risk of occupational stress. Considering the "low demand jobs" category as the standard, the increased risk of stress was associated with low education levels (odds ratio, 3.69, 95% CI, 1.64-8.28), working in bank agencies (odds ratio, 2.55, 95% CI, 1.36-4.77), a length of employment at the bank of more than five years (odds ratio, 3.32, 95% CI, 1.89-5.81), a daily work period of six hours (odds ratio, 2.72, 95% CI, 1.27-5.81), and, mainly, low social support (odds ratio, 2.57, 95% CI 1.45- 4.56).

Adults with congenital heart disease (CHD) face unique life courses and challenges that may negatively influence their psychological functioning. The aims of this study were to (1) examine the level of hopelessness among adults with CHD in comparison with non-CHD participants and (2) identify correlates of elevated hopelessness among adults with CHD. We enrolled 347 patients with CHD (18-64years, 52.2% female) and 353 matched (by sex/age) non-CHD persons in this cross-sectional study. Hopelessness was assessed by Beck Hopelessness Scale. Hierarchical multiple logistic regression analyses were performed to explore correlates of elevated hopelessness. The mean total hopelessness score did not significantly differ between the CHD and non-CHD groups. Twenty-eight percent of CHD patients had elevated hopelessness scores. Within the CHD patient sample, regression analyses revealed that being male (odds ratio=2.62), not having children (odds ratio=3.57), being unemployed (odds ratio=2.27), and elevated depressive symptoms (odds ratio=1.21) were significantly associated with hopelessness. Regular physical activity (odds ratio=0.36) emerged as a protective factor and all CHD disease parameters were unrelated to hopelessness. The final model explained 43% of the variance in hopelessness. Adult CHD teams are encouraged to continue to explore strategies to support patients to live as rich and full as lives as possible by pursuing relationships, employment and physical activity, as well as managing depression and hopelessness.

Globally, there are 3.3 million children < 15 years of age living with HIV infection. About 95% of HIV infected children have acquired infection from their mothers. Although new pediatric HIV infection in Tanzania has declined by 48% and Prevention of Mother to Child Transmission (PMTCT) coverage of highly active anti-retroviral therapy (HAART) has increased to 77%, the MTCT rate remains high (15%). Poor male partner involvement in PMTCT services is one of the factors contributing to reduced effectiveness of the PMTCT and hence failure to achieve the elimination of maternal to child transmission of HIV. This study examined the predictors of male involvement in PMTCT services in Mwanza Region, Tanzania from perspectives of the mother. A cross sectional study involving selected health facilities was conducted in Mwanza urban from October 2013 through January 2014. HIV positive pregnant women attending ante-natal clinic (ANC) were interviewed using a semi structured questionnaire. Univariate analysis was used to describe the study respondents where bivariate and logistic regression was used to determine predictors of male involvement. A total of 300 HIV positive mothers attending ANC with the mean age of 27.5 + 5.6 were interviewed. Few mothers (24.7%) had their male partners involved in PMTCT. Predictors of male partner involvement in PMTCT were mothers being proactive (Adjusted Odds Ratio (AOR) 28.6; Confidence Interval (CI) 7-116), perceived partners knowledge on PMTCT (AOR 24.6, CI 5.9-102.8), exposure to TV/Radio announcements on PMTCT (AOR 4.6, CI 1.5-14) and married status of the mother (AOR 3.7, CI 1.5-9). Mothers who never wanted to be escorted by their male partners and busy partners were associated with reduced odds of male involvement into PMTCT (AOR 0.07, CI 0.007-0.68) and (AOR 0.46 CI 0.21-0.99) respectively. Male partner involvement was associated with 98% reduced odds of violence (Crude Odds Ratio 0.018 CI 0.002-0.14). Male partner involvement in PMTCT is still low in Mwanza Region. Proactive mothers, partner's knowledge on PMTCT and announcements from television/radio were the major facilitating factors for male involvement in PMTCT as perceived by mothers. Busy male partners and mothers who did not want to be escorted by their partners were a hindrance to male involvement in PMTCT services. These factors highlight the importance of women role in promotion of PMTCT male involvement.

Missed conceptions or misconceptions: perceived infertility among unmarried young adults in the United States.

Perceived infertility is an individual's belief that she or he is unable to conceive or impregnate, regardless of whether this belief is medically accurate. This perception may lead to contraceptive nonuse, which may, in turn, lead to unintended pregnancy. Little research has examined perceived infertility among young adults, including potential associations with contraceptive behaviors. The frequency of perceived infertility among young adults was assessed using 2009 data from a nationally representative telephone survey of 1,800 unmarried men and women aged 18-29. Multinomial regression analyses assessed associations between respondents' perceived infertility and selected background, reproductive knowledge, sexual experience and contraceptive use characteristics. Overall, 19% of women and 13% of men believed that they were very likely to be infertile. Hispanic women and women who had received public assistance in the past year had elevated odds of perceived infertility (odds ratios, 3.4 and 3.0, respectively), as did Hispanic men and men of other racial or ethnic minorities, except blacks (2.5 and 6.1, respectively). Men who had some college education, had received sex education or were not in a current relationship had decreased odds of thinking they were very likely to be infertile (0.3-0.4). Among men, perceived infertility was associated with the belief that they were likely to have sex without using a contraceptive in the next three months (2.6). A substantial proportion of young adults believe they are infertile. Improved provider counseling and sex education may be useful in helping them to better understand their actual probability of infertility, and this knowledge may lead to improved contraceptive use.

In both the biomedical and public health literature, the risk for preterm birth has been linked to maternal racial/ethnic background, in particular African-American heritage. Despite this well-documented health disparity, the relationship of comorbid conditions, such as chronic hypertension, to maternal race/ethnicity and preterm birth has received relatively limited attention in the literature. The objective of the study was to evaluate the interaction between chronic hypertension and maternal racial/ethnic background on preterm birth. This is a retrospective cohort study of singleton pregnancies among women who delivered between 2002 and 2015 at the University of California, San Francisco. The associations of chronic hypertension with both spontaneous and medically indicated preterm birth were examined by univariate and multivariate logistical regression, adjusting for confounders including for maternal age, history of preterm birth, maternal body mass index, insurance type (public vs private), smoking, substance abuse, history of pregestational diabetes mellitus, and use of assisted reproductive technologies. The interaction effect of chronic hypertension and racial/ethnicity was also evaluated. All values are reported as odds ratios, with 95% confidence intervals and significance set at P = .05. In this cohort of 23,425 singleton pregnancies, 8.8% had preterm deliveries (3% were medically indicated preterm birth, whereas 5.5% were spontaneous preterm births), and 3.8% of women carried the diagnosis of chronic hypertension. Chronic hypertension was significantly associated with preterm birth in general (adjusted odds ratio, 2.74, P < .001) and medically indicated preterm birth specifically (adjusted odds ratio, 5.25, P < .001). When evaluating the effect of chronic hypertension within racial/ethnic groups, there was an increased odds of a preterm birth among hypertensive, African-American women (adjusted odds ratio, 3.91, P < .001) and hypertensive, Asian-American/Pacific Islander women (adjusted odds ratio, 3.51, P < .001) when compared with their nonhypertensive counterparts within the same racial/ethnic group. These significant effects were also noted with regard to medically indicated preterm birth for hypertensive African-American women (adjusted odds ratio, 6.85, P < .001) and Asian-American/Pacific Islander women (adjusted odds ratio, 9.87, P < .001). There was no significant association of chronic hypertension with spontaneous preterm birth (adjusted odds ratio, 0.87, P = .4). The effect of chronic hypertension on overall preterm birth and medically indicated preterm birth differs by racial/ethnic group. The larger effect of chronic hypertension among African-American and Asian/Pacific Islander women on medically indicated and total preterm birth rates raises the possibility of an independent variable that is not captured in the data analysis, although data regarding the indication for medically indicated preterm delivery was limited in this data set. Further investigation into both social-structural and biological predispositions to preterm birth should accompany research focusing on the effect of chronic hypertension on birth outcomes.

With a prevalence of 4% to 13% in the United States, autoimmune thyroiditis (AIT) is a major health problem. Besides somatic complications, patients with AIT can also experience psychiatric disorders. The extent of these organic psychiatric diseases in patients with AIT, however, is so far not commonly known. To provide meta-analytic data on the association of depression and anxiety with AIT. Google Scholar, the EBSCO Host databases, the Web of Knowledge, and PubMed were searched from inception through December 5, 2017. Articles identified were reviewed and reference lists were searched manually. Case-control studies that reported the association between AIT and either depression or anxiety disorders or both were included. Data extraction was performed by multiple observers following the PRISMA guidelines. Two univariate random-effects meta-analyses were performed, and moderators were tested with Bonferroni-corrected meta-regression analysis. Heterogeneity was assessed with the I2 statistic. Sensitivity analyses tested the robustness of the results. Small study effects were assessed with funnel plots and the Egger test. The odds ratio of patients with AIT and depression compared with a healthy control group, as well as the odds ratio of patients with AIT and anxiety disorders compared with a healthy control group. Nineteen studies comprising 21 independent samples were included, with a total of 36 174 participants (35 168 for depression and 34 094 for anxiety). Patients with AIT, Hashimoto thyroiditis, or subclinical or overt hypothyroidism had significantly higher scores on standardized depression instruments, with an odds ratio of 3.56 (95% CI, 2.14-5.94; I2 = 92.1%). For anxiety disorders, patients with AIT, Hashimoto thyroiditis, or subclinical or overt hypothyroidism had an odds ratio of 2.32 (95% CI, 1.40-3.85; I2 = 89.8%). Funnel plot asymmetry was detected for studies of depression. Study quality assessed with the Newcastle-Ottawa Scale for case-control studies (mean [SD] score: anxiety, 5.77 [1.17]; depression, 5.65 [1.14]; of a possible maximum score of 9) and proportion of females did not modulate the meta-analytic estimate, whereas mean age did. This meta-analysis establishes the association between AIT and depression and anxiety disorders. Patients with AIT exhibit an increased chance of developing symptoms of depression and anxiety or of receiving a diagnosis of depression and anxiety disorders. This finding has important implications for patients and could lead to the choice of early treatment-and not only psychotherapeutic treatment-of the organic disorder.

Background Heterosexual contact is the most common mode of HIV transmission in India that is largely linked to sex work. We assessed the non-use of condoms in sex work and with regular sex partners by female sex workers (FSWs), and identified its associations that could assist in planning HIV prevention programmes. Methods Detailed documentation of various aspects of sex work, and sexual behaviour with regular sex partners, was done through confidential interviews for 6648 FSWs in 13 districts in the Indian state of Andhra Pradesh. Multivariate analysis was done to understand condom non-use with clients. Results 5010 (75.4%), 1499 (22.5%), and 139 (2.1%) FSWs were street-, home-, and brothel-based, respectively. Of the total 6648 FSWs, 6165 (92.7%) had penetrative vaginal/anal sex with at least one client in the last 15 days, and of these 2907 (47.2%; 95% CI 41.2–53.2%) reported non-use of condom with at least one of her last three clients. Lack of knowledge that HIV could be prevented (odds ratio 5.01; 95% CI 4.38–5.73), no access to free condoms (odds ratio 3.45; 95% CI 2.99–3.98), being street-based as compared with brothel-based (odds ratio 3.36; 95% CI 1.87–6.04), and no participation in FSW support groups (odds ratio 2.02; 95% CI 1.50–2.70) were the most significant predictors of condom non-use with clients. Other associations included lower social support, lower income, age >24 years, illiteracy, and living in medium-size urban or rural areas. Of the 2582 who had penetrative sex with regular sex partner within the last 7 days, 2428 (94%; 95% CI 92.1–95.9%) had not used condom at last sex, and 1032 (41.8%) had neither used condom consistently with clients nor with regular sex partner. Conclusion About half the FSWs do not use condom consistently with their clients in this Indian state putting them at high risk of HIV infection. Non-brothel-based FSWs, who form the majority of sex workers in India, were at a significantly higher risk of HIV infection as compared with brothel-based FSWs. With their high vulnerability, the success of expansion of HIV prevention efforts will depend on achieving and sustaining an environment that enables HIV prevention with the non-brothel based FSWs.

Temperature data loggers were set to serially record the temperature within vaccine refrigerators in 28 general practices, recording at 12 minute intervals over a period of 10 days on each occasion. A survey of vaccine storage knowledge and records of divisions of general practice immunisation contacts were also obtained. There was a significant relationship between type of refrigerator and optimal temperature, with the odds ratio for bar style refrigerator being 0.005 (95% CI: 0.001-0.044) compared to the purpose built vaccine refrigerators. Score on a survey of vaccine storage was also positively associated with optimal storage temperature. General practices that invest in purpose built vaccine refrigerators will achieve standards of vaccine cold chain maintenance significantly more reliably than can be achieved through regular cold chain monitoring and practice supports.

A randomized control pilot study was conducted with Black men who have sex with men (BMSM; N = 42) aged 18-30 years to examine the feasibility of implementing a video intervention delivered using Facebook to motivate HIV testing. At baseline, participants were unaware of their HIV status and had not tested for HIV in the past 6 months, residing in Los Angeles County. The intervention content included topics such as social influence, HIV knowledge, stigma, HIV positive knowledge, and benefits of knowing one's HIV status. Logistic regression revealed that those receiving the video intervention were 7 times more likely to have tested for HIV than those in the control group at 6-week follow-up (odds ratio [ OR ] = 7.00, 95% confidence interval [1.72, 28.33], p = .006). Data suggest that the intervention was feasible for motivating HIV testing.

We determined the overall prevalence of typical orofacial clefts and the potential risks for nonsyndromic cleft lip with or without cleft palate in a university hospital from West México. For the prevalence, 227 liveborn infants with typical orofacial clefts were included from a total of 81,193 births occurred during the period 2009-2016 at the "Dr. Juan I. Menchaca" Civil Hospital of Guadalajara (Guadalajara, Jalisco, Mexico). To evaluate potential risks, a case-control study was conducted among 420 newborns, including only those 105 patients with nonsyndromic cleft lip with or without cleft palate (cases), and 315 infants without birth defects (controls). Data were analyzed using multivariable logistic regression analysis expressed as adjusted odds ratio with 95% confidence intervals . The overall prevalence for typical orofacial clefts was 28 per 10,000 (95% confidence interval: 24.3-31.6), or 1 per 358 live births. The mean values for the prepregnancy weight, antepartum weight, and pre-pregnancy body mass index were statistically higher among the mothers of cases. Infants with nonsyndromic cleft lip with or without cleft palate had a significantly higher risk for previous history of any type of congenital anomaly (adjusted odds ratio: 2.7; 95% confidence interval: 1.4-5.1), history of a relative with cleft lip with or without cleft palate (adjusted odds ratio: 19.6; 95% confidence interval: 8.2-47.1), and first-trimester exposures to progestogens (adjusted odds ratio: 6.8; 95% CI 1.8-25.3), hyperthermia (adjusted odds ratio: 3.4; 95% confidence interval: 1.1-10.6), and common cold (adjusted odds ratio: 3.6; 95% confidence interval: 1.1-11.9). These risks could have contributed to explain the high prevalence of orofacial clefts in our region of Mexico, emphasizing that except for history of relatives with cleft lip with or without cleft palate, most are susceptible of modification. © 2018 Japanese Teratology Society.

To determine the prevalence and distribution of abnormal plasma liver enzymes in a representative sample of older adults with Type 2 diabetes. Plasma concentrations of alanine aminotransferase, aspartate aminotransferase and γ-glutamyltransferase were measured in a randomly selected, population-based cohort of 1066 men and women aged 60-75 years with Type 2 diabetes (the Edinburgh Type 2 Diabetes Study). Overall, 29.1% (95% CI 26.1-31.8) of patients had one or more plasma liver enzymes above the upper limit of the normal reference range. Only 10.1% of these patients had a prior history of liver disease and a further 12.4% reported alcohol intake above recommended limits. Alanine aminotransferase was the most commonly raised liver enzyme (23.1% of patients). The prevalence of abnormal liver enzymes was significantly higher in men (odds ratio 1.40, 95% CI 1.07-1.83), in the youngest 5-year age band (odds ratio 2.02, 95% CI 1.44-2.84), in patients with diabetes duration < 5 years (odds ratio 1.38, 95% CI 1.01-1.90), plasma HbA(1c) ≥ 58 mmol/mol (7.5%) (odds ratio 1.43, 95% CI 1.09-1.88), obese BMI (odds ratio 2.84, 95% CI 1.59-3.06) and secondary care management for their diabetes (odds ratio 1.40, 95% CI 1.05-1.87). However, all these factors combined accounted for only 7.6% of the variation in liver enzyme abnormality. The prevalence of elevated liver enzymes in people with Type 2 diabetes is high, with only modest variation between clinically defined patient groups. Further research is required to determine the prognostic value of raised, routinely measured liver enzymes to inform decisions on appropriate follow-up investigations. © 2011 The Authors.

The goal of this study was to explore the association between neonatal infection and outcomes in children with cerebral palsy. We conducted a retrospective cohort study using the Canadian CP Registry. Neonatal infection was defined as meeting one of the following criteria: (1) septicemia, (2) septic shock, or (3) administration of antibiotics for ≥10 days. Phenotypic profiles of children with cerebral palsy with and without an antecedent neonatal infection were compared. Subgroup analysis was performed, stratified by gestational age (term versus preterm). Of the 1229 registry participants, 505 (41.1%) were preterm, and 192 (15.6%) met the criteria for neonatal infection with 29% of preterm children having a neonatal infection compared with 6.5% in term-born children. Children with prior neonatal infection were more likely to have a white matter injury (odds ratio 2.2, 95% confidence interval 1.5 to 3.2), spastic diplegic neurological subtype (odds ratio 1.6, 95% confidence interval 1.1 to 2.3), and sensorineural auditory impairment (odds ratio 2.1, 95% confidence interval 1.4 to 3.3). Among preterm children, neonatal infection was not associated with a difference in phenotypic profile. Term-born children with neonatal infection were more likely to have spastic triplegia or quadriplegia (odds ratio 2.4, 95% confidence interval 1.3 to 4.3), concomitant white matter and cortical injury (odds ratio 4.1, 95% confidence interval 1.6 to 10.3), and more severe gross motor ability (Gross Motor Function Classification System IV to V) (odds ratio 2.6, 95% confidence interval 1.4 to 4.8) compared with preterm children. Findings suggest a role of systemic infection on the developing brain in term-born infants, and the possibility to develop targeted therapeutic and preventive strategies to reduce cerebral palsy morbidity.

In fibrous dysplasia (BFD), normal bone and bone marrow are replaced by fibro-osseous tissue, leading to fracture, deformity and pain. BFD may be isolated, or in association with cutaneous hyperpigmentation and/or hyperfunctioning endocrinopathies, termed McCune-Albright syndrome (MAS). GH hypersecretion has been described in 10%-20% of MAS-BFD patients. Aim of the study was to determine the impact of GH-insulin like growth factor 1 (IGF1) axis hyperactivity on MAS-BFD morbidities and the efficacy of GH excess therapy. A multicentric cross-sectional analysis was conducted on three different MAS cohorts. From 195 MAS patients, 37 subjects (19%) with GH excess were identified and compared with 34 MAS controls without GH hypersecretion. Mean head circumference SDS was significantly higher in GH excess: 4.025 SDS vs 0.683 SDS (P < .0001). The risk of optic neuropathy (Odds ratio 4.231; P = .039), hearing deficit (Odds ratio 2.961; P = .0481), facial asymmetry (Odds ratio 6.563; P = .0192), malignancies (Odds ratio 15.24; P = .0173) were higher in GH excess group. Overall, pharmacotherapy (octreotide alone 10-30 mg/mo or with pegvisomant 10-20 mg/d) was effective in IGF1 normalization (IGF1 Z-score between -2 and +2 SDS) in 21/29 patients (72.4%) with good compliance to the regimen. Late diagnosis and GH excess treatment after 16 years old of age was associated with an increased risk of optic neuropathy (Odds ratio 4.500; P = .0491) and growth of pituitary adenomas (Odds ratio 7.846; P = .050). GH-IGF1 hyperactivity increases risk of morbidities in MAS. Medical therapy is effective in normalizing IGF1 in most patients, and early treatment during paediatric age is associated with a decreased risk of optic neuropathy and GH-secreting adenomas growth. © 2018 John Wiley & Sons Ltd.

Stroke rates are higher in men compared with women in the fourth through seventh decades of life, and higher rates may result from differences in carotid intraplaque hemorrhage (IPH), an unstable atherosclerotic plaque component. We report age-specific sex differences in the presence of magnetic resonance imaging-depicted carotid IPH. Patients (n=1115) underwent magnetic resonance imaging for carotid IPH between 2005 and 2014. Low-grade carotid stenosis patients (n=906) without prior endarterectomy were eligible for this cross-sectional study. Of the 906 patients included (mean age±SD in years, 66.98±15.15), 63 (6.95%) had carotid IPH. In men and women, carotid IPH was present in 11.43% (48 of 420) and 3.09% (15 of 486), respectively ( P <0.0001). Multivariable logistic regression analysis confirmed greater odds of carotid IPH in men for all ages: 45 to 54 (odds ratio=45.45; 95% confidence interval, 3.43-500), 55 to 64 years (odds ratio=21.74; 95% confidence interval, 3.21-142.86), 65 to 74 years (odds ratio=10.42; 95% confidence interval, 2.91-37.04), and ≥75 years (odds ratio=5.00; 95% confidence interval, 2.31-10.75). Male sex modified the effect of age on the presence of carotid IPH (β=0.074; SE=0.036; P =0.0411). Men have greater age-specific odds of magnetic resonance imaging-depicted carotid IPH compared with women. With increasing age post-menopause, the odds of carotid IPH in women becomes closer to that of men. Delayed onset of carotid IPH in women, an unstable plaque component, may partly explain differential stroke rates between sexes, and further studies are warranted. © 2017 American Heart Association, Inc.

The purpose of this study was to estimate the proportion of Norwegian coronary heart disease patients participating in cardiac rehabilitation programmes after percutaneous coronary intervention, and to determine predictors of cardiac rehabilitation participation. Participants were patients enrolled in the Norwegian Coronary Stent Trial. We assessed cardiac rehabilitation participation in 9013 of these patients who had undergone their first percutaneous coronary intervention during 2008-2011. Of these, 7068 patients (82%) completed a self-administered questionnaire on cardiac rehabilitation participation within three years after their percutaneous coronary intervention. Twenty-eight per cent of the participants reported engaging in cardiac rehabilitation. Participation rate differed among the four regional health authorities in Norway, varying from 20%-31%. Patients undergoing percutaneous coronary intervention for an acute coronary syndrome were more likely to participate in cardiac rehabilitation than patients with stable angina (odds ratio 3.2; 95% confidence interval 2.74-3.76). A multivariate statistical model revealed that men had a 28% lower probability ( p<0.001) of participating in cardiac rehabilitation, and the odds of attending cardiac rehabilitation decreased with increasing age ( p<0.001). Contributors to higher odds of cardiac rehabilitation participation were educational level >12 years (odds ratio 1.50; 95% confidence interval 1.32-1.71) and body mass index>25 (odds ratio 1.19; 95% confidence interval 1.05-1.36). Prior coronary artery bypass graft was associated with lower odds of cardiac rehabilitation participation (odds ratio 0.47; 95% confidence interval 0.32-0.70) Conclusion: The estimated cardiac rehabilitation participation rate among patients undergoing first-time percutaneous coronary intervention is low in Norway. The typical participant is young, overweight, well-educated, and had an acute coronary event. These results varied by geographical region.

Sleep problems are a well-known risk factor for work injuries, but less is known about which vulnerable populations are most at risk. The aims of this study were to investigate the association between sleep quality and the risk of work injury and to identify factors that may modify the association. A case-control study including 180 cases and 551 controls was conducted at the University Hospital in Basel, Switzerland, from 1 December 2009 to 30 June 2011. Data on work injuries and sleep quality were collected. Adjusted odds ratios and 95% confidence intervals of the association between sleep quality and work injury were estimated in multivariable logistic regression analyses and were stratified by hypothesized effect modifiers (age, gender, job risk, shift work, sleep duration and working hours). Poor sleep quality was associated significantly with work injury of any type (P < 0.05) and with being caught in particular (P < 0.05). The association between poor sleep quality and work injury was significantly higher for workers older than 30 years (odds ratio>30 1.30 versus odds ratio≤30 0.91, P < 0.01), sleeping 7 h or less per night (odds ratio≤7 1.17 versus odds ratio>7 0.79, P < 0.05) and working 50 h or more per week (odds ratio≥50 1.79 versus odd ratio<50 1.10, P < 0.01). Work injury risk increased with increasing severity of sleep problems (P < 0.05). Prior work injury frequency increased with decreasing sleep quality (P < 0.05). Older age, short sleep duration and long working hours may enhance the risk of work injuries associated with sleep quality. © 2014 European Sleep Research Society.

Hypocalcemia in dairy cows: meta-analysis and dietary cation anion difference theory revisited.

2006-02-01

Data from 137 published trials involving 2,545 calvings were analyzed using random effects normal logistic regression models to identify risk factors for clinical hypocalcemia in dairy cows. The aim of the study was to examine which form, if any, of the dietary cation anion difference (DCAD) equation provided the best estimate of milk fever risk and to clarify roles of calcium, magnesium, and phosphorus concentrations of prepartum diets in the pathogenesis of milk fever. Two statistically equivalent and biologically plausible models were developed that predict incidence of milk fever. These models were validated using data from 37 trials excluded from the original data used to generate the models; missing variables were replaced with mean values from the analyzed data. The preferred models differed slightly; Model 1 included prepartum DCAD, and Model 2 included prepartum dietary concentrations of potassium and sulfur alone, but not sodium and chloride. Other factors, included in both models were prepartum dietary concentrations of calcium, magnesium, phosphorus; days exposed to the prepartum diet; and breed. Jersey cows were at 2.25 times higher risk of milk fever than Holstein cows in Model 1. The results support the DCAD theory of greater risk of milk fever with higher prepartum dietary DCAD (odds ratio = 1.015). The only DCAD equation supported in statistical analyses was (Na(+) + K(+)) - (Cl(-) + S(2-)). This finding highlights the difference between developing equations to predict DCAD and those to predict milk fever. The results support a hypothesis of a quadratic role for Ca in the pathogenesis of milk fever (model 1, odds ratio = 0.131; Model 2, odds ratio = 0.115). Milk fever risk was highest with a prepartum dietary concentration of 1.35% calcium. Increasing prepartum dietary magnesium concentrations had the largest effect on decreasing incidence of milk fever in both Model 1 (odds ratio = 0.006) and Model 2 (odds ratio = 0.001). Increasing dietary phosphorus concentrations prepartum increased the risk of milk fever (Model 1, odds ratio = 6.376; Model 2, odds ratio = 9.872). The models presented provide the basis for the formulation of diets to reduce the risk of milk fever and strongly support the need to evaluate macro mineral nutrition apart from DCAD of the diet.

This study aimed to determine the association between infection with Toxoplasma gondii and epilepsy in patients attended to in a public hospital in the northern Mexican city of Durango. We performed an age- and gender-matched case-control study of 99 patients suffering from epilepsy and 99 without epilepsy. Sera of participants were analyzed for anti- T. gondii IgG and IgM antibodies using commercially available enzyme-linked immunoassays. Seropositive samples to T. gondii were further analyzed for detection of T. gondii DNA by polymerase chain reaction. Anti- T. gondii IgG antibodies were found in 10 (10.1%) of the 99 cases and in 6 (6.1%) of the 99 controls (odds ratio = 1.74; 95% confidence interval: 0.60-4.99; p = 0.43). High (> 150 IU/mL) levels of anti- T. gondii IgG antibodies were found in 6 of the 99 cases and in 4 of the 99 controls (odds ratio = 1.53; 95% confidence interval: 0.41-5.60; p = 0.74). Anti- T. gondii IgM antibodies were found in 2 of the 10 IgG seropositive cases, and in 2 of the 6 IgG seropositive controls (odds ratio = 0.50; 95% confidence interval: 0.05-4.97; p = 0.60). T. gondii DNA was not found in any of the 10 anti- T. gondii IgG positive patients. Bivariate analysis of IgG seropositivity to T. gondii and International Statistical Classification of Diseases and related Health Problems, 10th Edition codes of epilepsy showed an association between seropositivity and G40.1 code (odds ratio = 22.0; 95% confidence interval: 2.59-186.5; p = 0.008). Logistic regression analysis showed an association between T. gondii infection and consumption of goat meat (odds ratio = 6.5; 95% confidence interval: 1.22-34.64; p = 0.02), unwashed raw vegetables (odds ratio = 26.3; 95% confidence interval: 2.61-265.23; p = 0.006), and tobacco use (odds ratio = 6.2; 95% confidence interval: 1.06-36.66; p = 0.04). Results suggest that T. gondii infection does not increase the risk of epilepsy in our setting; however, infection might be linked to specific types of epilepsy. Factors associated with T. gondii infection found in this study may aid in the design of preventive measures against toxoplasmosis.

Ischemic time has prognostic importance in ST-elevation myocardial infarction patients. Mobile intensive care unit use can reduce components of total ischemic time by appropriate triage of ST-elevation myocardial infarction patients. Data from the Acute Coronary Survey in Israel registry 2000-2010 were analyzed to evaluate factors associated with mobile intensive care unit use and its impact on total ischemic time and patient outcomes. The study comprised 5474 ST-elevation myocardial infarction patients enrolled in the Acute Coronary Survey in Israel registry, of whom 46% ( n=2538) arrived via mobile intensive care units. There was a significant increase in rates of mobile intensive care unit utilization from 36% in 2000 to over 50% in 2010 ( p<0.001). Independent predictors of mobile intensive care unit use were Killip>1 (odds ratio=1.32, p<0.001), the presence of cardiac arrest (odds ratio=1.44, p=0.02), and a systolic blood pressure <100 mm Hg (odds ratio=2.01, p<0.001) at presentation. Patients arriving via mobile intensive care units benefitted from increased rates of primary reperfusion therapy (odds ratio=1.58, p<0.001). Among ST-elevation myocardial infarction patients undergoing primary reperfusion, those arriving by mobile intensive care unit benefitted from shorter median total ischemic time compared with non-mobile intensive care unit patients (175 (interquartile range 120-262) vs 195 (interquartile range 130-333) min, respectively ( p<0.001)). Upon a multivariate analysis, mobile intensive care unit use was the most important predictor in achieving door-to-balloon time <90 min (odds ratio=2.56, p<0.001) and door-to-needle time <30 min (odds ratio=2.96, p<0.001). One-year mortality rates were 10.7% in both groups (log-rank p-value=0.98), however inverse propensity weight model, adjusted for significant differences between both groups, revealed a significant reduction in one-year mortality in favor of the mobile intensive care unit group (odds ratio=0.79, 95% confidence interval (0.66-0.94), p=0.01). Among patients with ST-elevation myocardial infarction, the utilization of mobile intensive care units is associated with increased rates of primary reperfusion, a reduction in the time interval to reperfusion, and a reduction in one-year adjusted mortality.

Existing evidence of predictors of repeated teenage pregnancy has not been assessed rigorously. This systematic review provides a comprehensive evaluation of protective and risk factors that are associated with repeated teenage pregnancy through a metaanalytical consensus. We used PubMed, EMBASE, CINAHL, ProQuest, PsychINFO, ScienceDirect, Scopus, and Web of Science databases from 1997-2015 and the reference list of other relevant research papers and related reviews. Eligibility criteria included (1) epidemiologic studies that analyzed factors associated with repeated pregnancy or birth among adolescents <20 years of age who were nulliparous or experienced at least 1 pregnancy, and (2) experimental studies with an observational component that was adjusted for the intervention. We performed narrative synthesis of study characteristics, participant characteristics, study results, and quality assessment. We also conducted random-effects and quality-effects metaanalyses with meta-regression to obtain pooled odds ratios of identified factors and to determine sources of between-study heterogeneity. Twenty-six eligible epidemiologic studies, most from the United States (n=24), showed >47 factors with no evidence of publication bias for each metaanalysis. Use of contraception (pooled odds ratio, 0.60; 95% confidence interval, 0.35-1.02), particularly long-acting reversible contraceptives (pooled odds ratio, 0.19; 95% confidence interval, 0.08-0.45), considerably reduced repeated teenage pregnancy risk. Among studies about contraception, the number of follow-up visits (adjusted coefficient, 0.72; P=.102) and country of study (unadjusted coefficient, 2.57; permuted P=.071) explained between-study heterogeneity. Education-related factors, which included higher level of education (pooled odds ratio, 0.74; 95% confidence interval, 0.60-0.91) and school continuation (pooled odds ratio, 0.53; 95% confidence interval, 0.33-0.84), were found to be protective. Conversely, depression (pooled odds ratio, 1.46; 95% confidence interval, 1.14-1.87), history of abortion (pooled odds ratio, 1.66; 95% confidence interval, 1.08-2.54), and relationship factors, such as partner support, increased the repeated teenage pregnancy risk. Contraceptive use, educational factors, depression, and a history of abortion are the highly influential predictors of repeated teenage pregnancy. However, there is a lack of epidemiologic studies in low- and middle-income countries to measure the extent and characteristics of repeated teenage pregnancy across more varied settings.

Protein tyrosine phosphatase, non-receptor type 22 gene, which translates to lymphoid tyrosine phosphatase, is considered to be a susceptibility gene marker associated with several autoimmune diseases. Several studies have demonstrated the association of protein tyrosine phosphatase, non-receptor type 22 +1858C→T polymorphism with vitiligo. However, these studies showed conflicting results. Meta-analysis of the same was conducted earlier that included fewer number of publications in their study. We performed a meta-analysis of a total of seven studies consisting of 2094 cases and 3613 controls to evaluate the possible association of protein tyrosine phosphatase, non-receptor type 22 +1858C>T polymorphism with vitiligo susceptibility. We conducted a literature search in PubMed, Google Scholar and Dogpile for all published paper on protein tyrosine phosphatase, non-receptor type 22 +1858C→T polymorphism and vitiligo risk till June 2016. Data analysis was performed by RevMan 5.3 and comprehensive meta-analysis v3.0 software. Meta-analysis showed an overall significant association of protein tyrosine phosphatase, non- receptor type 22 +1858C→T polymorphism with vitiligo in all models (allelic model [T vs. C]: odds ratio = 1.50, 95% confidence interval [1.32-1.71], P< 0.001; dominant model [TT + CT vs. CC]: odds ratio = 1.61, 95% confidence interval [1.16-2.24], P = 0.004; recessive model [TT vs. CT + CC]: odds ratio = 4.82, 95% confidence interval [1.11-20.92], P = 0.04; homozygous model [TT vs. CC]: odds ratio = 5.34, 95% confidence interval [1.23-23.24], P = 0.03; co-dominant model [CT vs. CC]: odds ratio = 1.52, 95% confidence interval [1.09-2.13], P = 0.01). No publication bias was detected in the funnel plot study. Limited ethnic-based studies, unable to satisfy data by gender or vitiligo-type are some limitations of the present meta-analysis. Stratifying data by ethnicity showed an association of protein tyrosine phosphatase, non-receptor type 22 +1858C→T with vitiligo in European population (odds ratio = 1.53, 95% confidence interval [1.34-1.75], P< 0.001) but not in Asian population (odds ratio = 0.59, 95% confidence interval [0.26-1.32], P = 0.2). In conclusion, protein tyrosine phosphatase, non-receptor type 22 +1858 T allele predisposes European individuals to vitiligo.

Importance Residential (geographic) history and extent of solar exposure may be important risk factors for exfoliation syndrome, but detailed lifetime solar exposure has not been previously evaluated in exfoliation syndrome. Objective To assess the relation between residential history, solar exposure and exfoliation syndrome. Design Clinic-based, case control studies. Setting A clinical center in the United States and in Israel. Participants Exfoliation syndrome cases and controls (all 60+ years old Caucasians) enrolled from 2010 to 2012 (United States: 118 cases and 106 controls; Israel: 67 cases and 72 controls). Main Outcomes and Measures Weighted lifetime average latitude of residence and average number of hours per week spent outdoors as determined by validated questionnaires. Results In multivariable analyses, each degree of weighted lifetime average residential latitude away from the equator was associated with an 11% increased odds of exfoliation syndrome (pooled odds ratio = 1.11; 95% CI: 1.05-1.17; p < .001). Furthermore, every hour per week spent outdoors during the summer, averaged over a lifetime, was associated with a 4% increased odds of exfoliation syndrome (pooled odds ratio = 1.04; 95% CI: 1.00-1.07; p = .03). For every 1% of average lifetime summer time between 10 a.m. and 4 p.m. that sunglasses were worn, the odds of exfoliation syndrome decreased by 2% (odds ratio = 0.98; 95% CI: 0.97-0.99; p < .001) in the United States, but not in Israel (odds ratio = 1.00; 95% CI: 0.99-1.01; p = .92; p for heterogeneity = .005). In the United States, after controlling for important environmental covariates, history of work over water or snow was associated with increased odds of exfoliation syndrome (odds ratio = 3.86; 95% CI: 1.36-10.9); in Israel, there were too few people with such history for analysis. We did not identify an association between brimmed hat wear and exfoliation syndrome (p>.57). Conclusion and Relevance Lifetime outdoor activities may contribute to exfoliation syndrome. The association with work over snow or water and the lack of association with brimmed hat wear suggests that ocular exposure to light from reflective surfaces may be an important type of exposure in exfoliation syndrome etiology.

Cancer-related financial burden has been linked to cancer survivors (CS) forgoing/delaying medical care, skipping follow-up visits, and discontinuing medications. To the authors' knowledge, little is known regarding the effect of financial burden on the health-related quality of life of CS. The authors analyzed 2011 Medical Expenditure Panel Survey data. Financial burden was present if one of the following problems was reported: borrowed money/declared bankruptcy, worried about paying large medical bills, unable to cover the cost of medical care visits, or other financial sacrifices. The following outcomes were evaluated: Physical Component Score (PCS) and Mental Component Score (MCS) of the 12-Item Short-Form Health Survey (SF-12), depressed mood, psychological distress, and worry related to cancer recurrence. The authors also assessed the effect of the number of financial problems on these outcomes. Of the 19.6 million CS analyzed, 28.7% reported financial burden. Among them, the average PCS (42.3 vs 44.9) and MCS (48.1 vs 52.1) were lower for those with financial burden versus those without. In adjusted analyses, CS with financial burden had significantly lower PCS (β = -2.45), and MCS (β = -3.05), had increased odds of depressed mood (odds ratio, 1.95), and were more likely to worry about cancer recurrence (odds ratio, 3.54). Survivors reporting ≥ 3 financial problems reported statistically significant and clinically meaningful differences (≥3 points) in the mean PCS and MCS compared with survivors without financial problems. Cancer-related financial burden was associated with lower health-related quality of life, increased risk of depressed mood, and a higher frequency of worrying about cancer recurrence among CS. © 2015 American Cancer Society.

BACKGROUND AND OBJECTIVES: Adopting the milliliter as the preferred unit of measurement has been suggested as a strategy to improve the clarity of medication instructions; teaspoon and tablespoon units may inadvertently endorse nonstandard kitchen spoon use. We examined the association between unit used and parent medication errors and whether nonstandard instruments mediate this relationship. METHODS: Cross-sectional analysis of baseline data from a larger study of provider communication and medication errors. English- or Spanish-speaking parents (n = 287) whose children were prescribed liquid medications in 2 emergency departments were enrolled. Medication error defined as: error in knowledge of prescribed dose, error in observed dose measurement (compared to intended or prescribed dose); >20% deviation threshold for error. Multiple logistic regression performed adjusting for parent age, language, country, race/ethnicity, socioeconomic status, education, health literacy (Short Test of Functional Health Literacy in Adults); child age, chronic disease; site. RESULTS: Medication errors were common: 39.4% of parents made an error in measurement of the intended dose, 41.1% made an error in the prescribed dose. Furthermore, 16.7% used a nonstandard instrument. Compared with parents who used milliliter-only, parents who used teaspoon or tablespoon units had twice the odds of making an error with the intended (42.5% vs 27.6%, P = .02; adjusted odds ratio=2.3; 95% confidence interval, 1.2–4.4) and prescribed (45.1% vs 31.4%, P = .04; adjusted odds ratio=1.9; 95% confidence interval, 1.03–3.5) dose; associations greater for parents with low health literacy and non–English speakers. Nonstandard instrument use partially mediated teaspoon and tablespoon–associated measurement errors. CONCLUSIONS: Findings support a milliliter-only standard to reduce medication errors.

Objectives This study assessed medication adherence and hypertension knowledge, and their predictive factors, in people with hypertension, living in rural communities in Indonesia. Methods Data were acquired from 384 people living in eight rural villages via a researcher-administered questionnaire, a validated adherence scale, and a standardized hypertension knowledge survey. Multivariate analysis was used to identify the predictors of adherence and knowledge. Results Fifty-nine (15%) participants had good hypertension knowledge (score ≥ 8 out of 10). Compared to participants with poor knowledge, these participants had higher formal education (odds ratio = 2.7, 95% confidence interval = 1.5-4.7), and lived closer to a community health center (odds ratio = 1.8, 95% confidence interval = 1.0-3.3). Knowledge gaps about the need for long-term medication, hypertension complications, and the target blood pressure were identified. Good hypertension knowledge predicted good adherence to medication (odds ratio = 7.1, 95% confidence interval = 3.3-15.2). Only 42 (11%) participants were considered to have good adherence. Reasons for intentional nonadherence were beliefs that medicines should be taken only when symptoms are evident, limited access to healthcare services, and a preference using traditional medicines. Conclusion Strategies for addressing knowledge gaps and misconceptions about hypertension medication are needed, particularly for people with a low educational level and those living some distances from healthcare facilities.

The purpose of this study was to examine, among the general public, the independent effect of race on women's use of health information resources. A population-based random-digit dialing survey of adult women, aged 18 to 64 years, was conducted between October 1999 and January 2000. Subjects included 509 women (341 white women, 135 black women, and 33 women of other races). The response rate was 66%. The main outcome variable was the use of health information resources (print health or news media, broadcast media, computer resources [Internet], health organizations, organized health events). Logistic regression was used to determine the independent effect of race/ethnicity on the use of different information resources, with an adjustment for age, income, education, and marital status. After the adjustment for socioeconomic factors, black women had <50% odds of using print news media (odds ratio, 0.5; 95% CI, 0.4-0.8), <60% odds of using computer-based resources (odds ratio, 0.4; 95% CI, 0.2-0.6), and <70% odds of using health policy organizations (odds ratio, 0.3; 95% CI, 0.2-0.7), compared with white women. There is a large racial disparity in women's use of health information resources. Traditional sources that are used to provide patient information may not be effective in certain populations.

Family relationships are widely recognized as playing a role in adolescent alcohol use. Although family relationships and parenting vary by culture, limited research has explored these relationships in Latin America. We sought to determine which family factors are associated with adolescent alcohol use in Callao, Peru. Data come from a cross-sectional survey conducted in a public secondary school in Callao, Peru in 2007. A total of 180 11th grade students are included in the analysis. Our main outcome measure was problem drinking, defined as self-report of having ever consumed beer, wine, spirits, or hard alcohol to a point of drunkenness. Logistic regression was used to determine if odds of problem drinking varied by level of parental monitoring (knowledge of activities and whereabouts), positive family relationships, or family conflict, while controlling for demographic and peer variables. Low levels of parental monitoring and low levels of positive family relationships were each associated with significantly higher odds of lifetime problem drinking in analyses adjusted for deviant peer affiliation along with sociodemographic variables (odds ratio (OR) = 4.2; 95% confidence interval (CI): 1.3-13.5; OR = 4.4; 95% CI: 1.5-13.0, respectively). Although family conflict was associated with elevated odds of lifetime problem drinking, this did not reach significance (adjusted OR = 2.01; 95% CI: 0.8-5.1). Conclusions/Importance: Interventions designed to prevent adolescent alcohol use in urban Peru may benefit from promoting positive family interactions and parental monitoring skills.

Corporal punishment is closely related to physical abuse of children and is associated with several negative characteristics and experiences in children and youths. This study examined the relative unique contribution of 6 variables (social support, socioeconomic status, depression, self-efficacy, knowledge of child development, and history of postpartum depression) to maternal corporal punishment of children. A sample of 76 mothers was dichotomized into those who never spanked or hit with an object and those who have spanked or hit with an object. The mothers were recruited from a community mental health agency, an urban community center, and a court of common pleas. The measures in the present study were administered prior to mothers' participation in a parent training program. Mothers referred by the court of common pleas were mandated to participate in the parent training program, and the mothers from the community mental health agency and the urban community center volunteered to participate in the parent training program. However, all participants voluntarily completed the research measures. Binary logistic regression identified postpartum depression as the only variable to significantly increase the odds of corporal punishment (odds ratio = 6.307, 95% confidence interval = 1.098-36.214, p = .039). The findings demonstrate increased odds of corporal punishment among a high-risk sample of women with postpartum depression. The generalizability of these findings may be limited to low socioeconomic class and White and African American mothers enrolled in parent-training programs.

Several countries developed guidelines in order to provide a systematic approach for treatment of (chronic) lower back pain. The risk of suffering from (chronic) lower back pain differs significantly within the general population. A serious lack of research exists concerning the risk factor "dysfunctional behavior of the subjects in terms of acute lower back pain." The purpose of this study was to assess the knowledge of the German population regarding the availability of guidelines about managing lower back pain. Prospective observational cohort study. We interviewed 983 subjects by phone. The study population included 50 - 70-year-old men and women with German residency and sufficient language ability. Of all the subjects, 70.2% claimed that they suffered at least once in their lifetime with lower back pain. Lower back pain with radiating symptoms occurred in 28.7%. Women were affected significantly more frequently compared to the epidemiological data. Of all the subjects with lower education, 82.9% suffered from lower back pain at least once in their lifetime compared to only 62.4% of people with university degrees. Education was also a protective factor for lower back pain with radiating pain. People who completed secondary modern school were 42% less likely to suffer from lower back pain than those who did not graduate. Knowing active rules of conduct occurred significantly more often at higher educational levels (i.e. all kinds of sports and exercises requiring physical strength, flexibility, power, agility, coordination, grace, balance and control, in particular stretching exercises) odds ratio = 7.78, physical activities odds ratio = 3.92, relaxation exercises odds ratio = 3.51). Data acquisition was performed by an external company and therefore provided only limited options for external validity. Furthermore data acquisition was restricted to 50 - 70-year-old patients, since this age group is at higher risk of suffering from lower back pain. A conclusion upon the knowledge of the whole population has to be drawn with caution, especially when considering the size of the study population. The life-time prevalence of lower back pain was assessed by interviewing patients about prior episodes of lower back pain. Slightly biased results may have occurred since the memory of prior episodes might result in too many or too few episodes. The study revealed a lack of awareness of common available guidelines and an uneven distribution of existing knowledge throughout the population. Passive coping strategies like taking pain medication or ointment therapy were favored over active coping strategies like gymnastics, physical activities, and relaxation exercises. Respondents with a higher level of education suffered significantly less often from lower back pain and tended toward active treatment strategies. Respondents with lower levels of education more often demanded passive treatment strategies. The general population, especially those with lower education, is not sufficiently aware of behavioral strategies for managing lower back pain as proposed in available guidelines.

Cardiovascular risk assessment might be improved with the addition of emerging, new tests derived from atherosclerosis imaging, laboratory tests or functional tests. This article reviews relative risk, odds ratios, receiver-operating curves, posttest risk calculations based on likelihood ratios, the net reclassification improvement and integrated discrimination. This serves to determine whether a new test has an added clinical value on top of conventional risk testing and how this can be verified statistically. Two clinically meaningful examples serve to illustrate novel approaches. This work serves as a review and basic work for the development of new guidelines on cardiovascular risk prediction, taking into account emerging tests, to be proposed by members of the 'Taskforce on Vascular Risk Prediction' under the auspices of the Working Group 'Swiss Atherosclerosis' of the Swiss Society of Cardiology in the future.

Lower socioeconomic status is associated with cardiovascular disease. We sought to determine whether there is a higher prevalence of peripheral artery disease (PAD) in individuals with lower socioeconomic status. We analyzed data from the National Health and Nutrition Examination Survey 1999 to 2004. PAD was defined based on an ankle.brachial index .0.90. Measures of socioeconomic status included poverty.income ratio,a ratio of self-reported income relative to the poverty line, and attained education level. Of 6791 eligible participants,overall weighted prevalence of PAD was 5.8% (SE, 0.3). PAD prevalence was significantly higher in individuals with low income and lower education. Individuals in the lowest of the 6 poverty.income ratio categories had more than a2-fold increased odds of PAD compared with those in the highest poverty-income ratio category (odds ratio, 2.69; 95%confidence interval, 1.80.4.03; P<0.0001). This association remained significant even after multivariable adjustment(odds ratio, 1.64; 95% confidence interval, 1.04.2.6; P=0.034). Lower attained education level also associated with higher PAD prevalence (odds ratio, 2.8; 95% confidence interval, 1.96.4.0; P<0.0001) but was no longer significant after multivariable adjustment. Low income and lower attained education level are associated with PAD in US adults. These data suggest that individuals of lower socioeconomic status remain at high risk and highlight the need for education and advocacy efforts focused on these at-risk populations.

Ethnic differences in outcomes among children with nephrotic syndrome are unknown. We conducted a longitudinal study at a single regional pediatric center comparing ethnic differences in incidence from 2001 to 2011 census data and longitudinal outcomes, including relapse rates, time to first relapse, frequently relapsing disease, and use of cyclophosphamide. Among 711 children, 24% were European, 33% were South Asian, 10% were East/Southeast Asian, and 33% were of other origins. Over 10 years, the overall incidence increased from 1.99/100,000 to 4.71/100,000 among children ages 1-18 years old. In 2011, South Asians had a higher incidence rate ratio of 6.61 (95% confidence interval, 3.16 to 15.1) compared with Europeans. East/Southeast Asians had a similar incidence rate ratio (0.76; 95% confidence interval, 0.13 to 2.94) to Europeans. We determined outcomes in 455 children from the three largest ethnic groups with steroid-sensitive disease over a median of 4 years. South Asian and East/Southeast Asian children had significantly lower odds of frequently relapsing disease at 12 months (South Asian: adjusted odds ratio; 0.55; 95% confidence interval, 0.39 to 0.77; East/Southeast Asian: adjusted odds ratio; 0.42; 95% confidence interval, 0.34 to 0.51), fewer subsequent relapses (South Asian: adjusted odds ratio; 0.64; 95% confidence interval, 0.50 to 0.81; East/Southeast Asian: adjusted odds ratio; 0.47; 95% confidence interval, 0.24 to 0.91), lower risk of a first relapse (South Asian: adjusted hazard ratio, 0.74; 95% confidence interval, 0.67 to 0.83; East/Southeast Asian: adjusted hazard ratio, 0.65; 95% CI, 0.63 to 0.68), and lower use of cyclophosphamide (South Asian: adjusted hazard ratio, 0.82; 95% confidence interval, 0.53 to 1.28; East/Southeast Asian: adjusted hazard ratio, 0.54; 95% confidence interval, 0.41 to 0.71) compared with European children. Despite the higher incidence among South Asians, South and East/Southeast Asian children have significantly less complicated clinical outcomes compared with Europeans.

The safety of healthy living donors who are undergoing hepatic resection is a primary concern. We aimed to identify intraoperative anaesthetic and surgical factors associated with delayed recovery of liver function after hepatectomy in living donors. We retrospectively analysed 1969 living donors who underwent hepatectomy for living donor liver transplantation. Delayed recovery of hepatic function was defined by increases in international normalised ratio of prothrombin time and concomitant hyperbilirubinaemia on or after post-operative day 5. Univariate and multivariate logistic regression analyses were performed to determine the factors associated with delayed recovery of hepatic function after living donor hepatectomy. Delayed recovery of liver function after donor hepatectomy was observed in 213 (10.8%) donors. Univariate logistic regression analysis showed that sevoflurane anaesthesia, synthetic colloid, donor age, body mass index, fatty change and remnant liver volume were significant factors for prediction of delayed recovery of hepatic function. Multivariate logistic regression analysis showed that independent factors significantly associated with delayed recovery of liver function after donor hepatectomy were sevoflurane anaesthesia (odds ratio = 3.514, P < 0.001), synthetic colloid (odds ratio = 1.045, P = 0.033), donor age (odds ratio = 0.970, P = 0.003), female gender (odds ratio = 1.512, P = 0.014) and remnant liver volume (odds ratio = 0.963, P < 0.001). Anaesthesia with sevoflurane was an independent factor in predicting delayed recovery of hepatic function after donor hepatectomy. Although synthetic colloid may be associated with delayed recovery of hepatic function after donor hepatectomy, further study is required. These results can provide useful information on perioperative management of living liver donors. © 2015 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

To determine the influence of admission anthropometry on clinical outcomes in mechanically ventilated children in the PICU. Data from two multicenter cohort studies were compiled to examine the unique contribution of nutritional status, defined by body mass index z score, to 60-day mortality, hospital-acquired infections, length of hospital stay, and ventilator-free days, using multivariate analysis. Ninety PICUs from 16 countries with eight or more beds. Children aged 1 month to 18 years, admitted to each participating PICU and requiring mechanical ventilation for more than 48 hours. Data from 1,622 eligible patients, 54.8% men and mean (SD) age 4.5 years (5.1), were analyzed. Subjects were classified as underweight (17.9%), normal weight (54.2%), overweight (14.5%), and obese (13.4%) based on body mass index z score at admission. After adjusting for severity of illness and site, the odds of 60-day mortality were higher in underweight (odds ratio, 1.53; p < 0.001) children. The odds of hospital-acquired infections were higher in underweight (odds ratio, 1.88; p = 0.008) and obese (odds ratio, 1.64; p < 0.001) children. Hazard ratios for hospital discharge were lower among underweight (hazard ratio, 0.71; p < 0.001) and obese (hazard ratio, 0.82; p = 0.04) children. Underweight was associated with 1.3 (p = 0.001) and 1.6 (p < 0.001) fewer ventilator-free days than normal weight and overweight, respectively. Malnutrition is prevalent in mechanically ventilated children on admission to PICUs worldwide. Classification as underweight or obese was associated with higher risk of hospital-acquired infections and lower likelihood of hospital discharge. Underweight children had a higher risk of mortality and fewer ventilator-free days.

In patients with type 2 diabetes, microalbuminuria is an early clinical sign suggestive of vascular damage to the glomerulus. Microalbuminuria has also been currently reported as an important risk factor for cardiovascular disease and becomes relevant in the management of type 2 diabetes. This study is to determine the prevalence of microalbuminuria, identify the risk factors associated with microalbuminuria in type 2 diabetes, and to asses the achievement of treatment goals for cardiovascular risk reduction in type 2 diabetics. Seventy- two subjects with microalbuminuria were recruited from three hundred consecutively screened type 2 diabetics attending the Diabetic Clinic at the Lagos University Teaching Hospital. Clinical data were obtained by interviewing the participants. Anthropometric measurements were made and blood specimens were collected for analysis. The prevalence of microalbuminuria was twenty-four percent (24%) in type 2 diabetes. Multiple logistic regression identified duration of diabetes (odds ratio 1.3 (95% CI; 0.03-1.58), hypertension(odds ratio 5.2 (95% Cl; 1.24-18.62), Body mass index (BMI) (odds ratio 1.27 (95% CI; 1.0-1.6), waist/hip ratio (WHR) (odds ratio 1.9 (95% Cl; 1.3-3.5), andHbA,c (odds ratio 6.6 (95% Cl; 1.02-27) as independent risk factors associated with microalbuminuria in type 2 diabetics. Optimum blood pressure, glycemic and weight control were achieved in eighty five percent (85%), fifty eight percent (58%) and nineteen percent (19%) of the type 2 diabetes respectively. This study showed that microalbuminuria is common among patients with type 2 diabetes. It also showed improvement in glycemic control and modifiable cardiovascular risk factor control when compared with previous studies.

2009-05-01

The relative performance of asthma care quality measures has not been evaluated in Medicaid populations. Using complete claims and pharmaceutical data for 19,076 patients with persistent asthma (based on Health Effectiveness and Data Information Set criteria) in five Medicaid populations, we compared the following two measures of asthma care quality: filling prescriptions for controller asthma medications within 1 year and the ratio of controller medication to the total number of asthma medication prescriptions filled within 1 year. We calculated whether meeting each quality measure was associated with decreased odds of emergency department (ED) treatment episodes. We then compared the odds ratios, receiver operating characteristic (ROC) curves, and deviances between models, using each measure to predict ED utilization in Medicaid populations. Although meeting each measure was associated with lower odds of ED utilization, this decrease was larger if the controller asthma medication measure was met rather than the ratio measure. Additionally, models using the controller medication measure had greater areas under the ROC curve and smaller deviances than models using the ratio measure. Both administrative measures of asthma care quality were associated with lower odds of ED utilization. The controller medication measure of asthma care quality may be better than the ratio measure in relation to emergency asthma care utilization by Medicaid beneficiaries.

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

Background Childhood abuse is a major global and public health problem associated with a myriad of adverse outcomes across the life course. Suicide is one of the leading causes of mortality during the perinatal period. However, few studies have assessed the relationship between experiences of childhood abuse and suicidal ideation in pregnancy. Objective To examine the association between exposure to childhood abuse and suicidal ideation among pregnant women. Study Design A cross-sectional study was conducted among 2,964 pregnant women attending prenatal clinics, in Lima, Peru. Childhood abuse was assessed using the Childhood Physical and Sexual Abuse Questionnaire. Depression and suicidal ideation were assessed using the Patient Health Questionnaire-9 scale. Logistic regression procedures were performed to estimate adjusted odds ratios and 95% confidence intervals adjusted for potential confounders. Results Overall, the prevalence of childhood abuse in this cohort was 71.8% and antepartum suicidal ideation was 15.8%. The prevalence of antepartum suicidal ideation was higher among women who reported experiencing any childhood abuse compared to those reporting none (89.3% vs. 10.7%, P<0.0001). After adjusting for potential confounders, including antepartum depression and lifetime intimate partner violence, those with history of any childhood abuse had a 2.9-fold (adjusted odds ratios; 95% confidence intervals: 2.12-3.97) increased odds of reporting suicidal ideation. Women who experienced both physical and sexual childhood abuse had much higher odds of suicidal ideation (adjusted odds ratios =4.04; 95% confidence intervals: 2.88-5.68). Women who experienced any childhood abuse and reported depression had 3.44-fold (adjusted odds ratios; 95% confidence intervals: 1.84-6.43) increased odds of suicidal ideation compared with depressed women with no history of childhood abuse. Finally, the odds of suicidal ideation increased with increased number of childhood abuse events experienced (P-value for trend<0.001). Conclusion Maternal history of childhood abuse was associated with increased odds of antepartum suicidal ideation. It is important for clinicians to be aware of the potential increased risk of suicidal behaviors among pregnant women with a history of childhood physical and sexual abuse. PMID:27173085

The aim of this study was to assess the relationship between exposure to physical and organizational job stressors during pregnancy and cesarean delivery. We sampled 580 employed women in California who participated in a nested population-based case-control study of birth outcomes. Adjusted multivariate regression analyses estimated associations between heavy lifting, frequent bending, high noise, extreme temperature, prolonged standing and organizational stressors (shift work, inflexible schedules, effort-reward ratio), and primary cesarean (vs vaginal) delivery, controlling for covariates. Women occupationally exposed had higher odds of cesarean. Those exposed to daily manual lifting more than 15 pounds [adjusted odds ratio = 2.54; 95% confidence interval (95% CI) 1.21 to 5.32] and at least four physical job stressors (adjusted odds ratio = 3.49; 95% CI 1.21 to 10.09) had significantly elevated odds of cesarean delivery. Exposed morbid women experienced greater risk; risk was lower among those with schedule flexibility. Associations were found between modifiable exposure to physical job stressors during pregnancy and cesarean delivery.

The reasons for low adherence to cereal dietary guidelines are not well understood but may be related to knowledge, attitudes, beliefs and perceived barriers. This study aims to assess trends in cereal foods consumption, intention to change and factors associated with intake among Western Australian (WA) adults 18 to 64 years. Cross-sectional data from the 1995, 1998, 2001, 2004, 2009, and 2012 Nutrition Monitoring Survey Series involving 7044 adults were pooled. types and amount of cereals (bread, rice, pasta, and breakfast cereal) eaten the day prior. Attitudes, knowledge, intentions, weight status and sociodemographic characteristics were measured. Descriptive statistics, multiple binary logistic and multinomial logistic regressions assess factors associated with consumption. Bread (78%) was the most commonly consumed cereal food. The proportion eating bread decreased across survey years (Odds Ratio OR = 0.31; 95% Confidence Interval; 0.24-0.40 in 2012 versus 1995), as did the amount (4.1 slices of bread in 1995 to 2.4 in 2012). The odds of consuming whole-grain cereal foods increased since 2009 (OR = 1.27; 1.02-1.58 versus 1995 p < 0.05). The likelihood of trying to eat less cereal food in the past year was greater in 2012 compared to 1995 (Relative Risk Ratio RRR 10.88; 6.81-17.4). Knowledge of cereal recommendations decreased over time (OR = 0.20; 0.15-0.27 in 2012 versus 1995 p < 0.001). Overweight and obese respondents were more likely than healthy weight respondents to have tried to eat less cereals (RRR 1.65; 1.22-2.24 and 1.88; 1.35-2.63 respectively). 'I already eat enough' was the main barrier (75% in 1995 to 84% in 2012 (p < 0.001)). WA adults are actively reducing the amount of cereal foods they eat and intake is associated with a misperception of adequacy of intake. Nutrition intervention is needed to increase awareness of the health benefits of cereal foods, particularly whole-grains, and to address barriers to incorporating them daily. Not applicable.

Background The aims of the study were to evaluate the effect of providing tailored falls prevention education in hospital on: i) engagement in targeted falls prevention behaviors in the month after discharge: ii) patients’ self-perceived risk and knowledge about falls and falls prevention strategies after receiving the education. Methods A pilot randomized controlled trial (n = 50): baseline and outcome assessments conducted by blinded researchers. Participants: hospital inpatients 60 years or older, discharged to the community. Participants were randomized into two groups. The intervention was a tailored education package consisting of multimedia falls prevention information with trained health professional follow-up, delivered in addition to usual care. Outcome measures were engagement in falls prevention behaviors in the month after discharge measured at one month after discharge with a structured survey, and participants’ knowledge, confidence and motivation levels before and after receiving the education. The feasibility of providing the intervention was examined and falls outcomes (falls, fall-related injuries) were also collected. Results Forty-eight patients (98%) provided follow-up data. The complete package was provided to 21 (84%) intervention group participants. Participants in the intervention group were significantly more likely to plan how to safely restart functional activities [Adjusted odds ratio 3.80, 95% CI (1.07, 13.52), p = 0.04] and more likely to complete other targeted behaviors such as completing their own home exercise program [Adjusted odds ratio 2.76, 95% CI (0.72, 10.50), p = 0.14] than the control group. The intervention group was significantly more knowledgeable, confident and motivated to engage in falls prevention strategies after receiving the education than the control group. There were 23 falls (n = 5 intervention; n = 18 control) and falls rates were 5.4/1000 patient days (intervention); 18.7/1000 patient days (control). Conclusion This tailored education was received positively by older people, resulted in increased engagement in falls prevention strategies after discharge and is feasible to deliver to older hospital patients. Trial registration The study was registered with the Australian New Zealand Clinical Trials Registry; ACTRN12611000963921 on 8th November 2011. PMID:23717424

To determine frequency of depression in patients with diabetes mellitus type 2 and to identify predictive factors. The observational study was carried out at 1 Mountain Medical Battalion, Bagh, Azad Kashmir, Pakistan, from June 2013 to May 2014, and comprised type 2 diabetic patients who were not using anti-depressants and did not have history of other psychiatric illnesses. Demographic data, duration of diabetes, presence of hypertension and type of treatment were recorded and body mass index was calculated. Patient Health Questionnaire-9, translated into Urdu, was administered during face-to-face interviews. Scores >5 indicated depression, which was classified into different grades of severity using standard cut-off values. Of the 133 patients, 51(38.35%) were depressed. Depression was mild in 34(26%), moderate in 12(9.6%), moderately severe in 4(2.9%) and severe in 1(0.7%) patient. On univariate binary logistic regression, female gender (odds ratio=3.07; 95% confidence interval = 1.43, 6.59), lesser education (odds ratio = 0.90; 95% confidence interval 0.84, 0.97) shorter duration of diabetes (odds ratio=0.87; 95% confidence interval = 0.80, 0.96) and higher body mass index (odds ratio=1.41; 95% confidence interval = 1.05, 1.25) were significantly associated with depression. Only shorter duration of diabetes (odds ratio=0.90; 95% confidence interval = 0.82, 0.99) remained significant after adjustment for confounders. Age, level of education, glycaemic control and type of treatment did not predict depression. A significant proportion of type 2 diabetics were depressed. Shorter duration of diabetes reliably predicted depression in these patients.

Evaluate racial disparities in sepsis processes of care. Observational cohort study. Nine hospitals in the Southeastern United States between 2014 and 2016. Two thousand two hundred twenty-one white and 707 black patients treated in the emergency department through "code sepsis" pathway for suspected septic shock. Black patients were less likely to receive timely antibiotics than were white patients using multiple definitions (1 hr from code sepsis activation [odds ratio, 0.57; 95% CI, [0.44-0.74]; 85.6% vs. 91.2%; p < 0.0001]; 1 hr from triage [odds ratio, 0.83; 95% CI, [0.69-1.00]; 28.0% vs. 31.8%; p = 0.06]; 3 hr from triage [odds ratio, 0.71; 95% CI, [0.57-0.88]; 80.1% vs. 85.0%; p = 0.002]). Focusing on antibiotic administration within 1 hour of triage, these differences were enhanced after adjusting for patient-level factors (adjusted odds ratio, 0.80; 95% CI, [0.66-0.96]; p = 0.02), but attenuated after adjusting for hospital-level differences (adjusted odds ratio, 0.90; 95% CI, [0.81-1.01]; p = 0.07). Black and white patients did not differ on other sepsis quality indicators or adjusted mortality. Black patients appear to be less likely than white patients to receive timely antibiotic therapy for sepsis. These differences were largely explained by variation in care among hospitals, such that hospitals that disproportionately treat black patients were less likely to provide timely antibiotic therapy overall. There were no differences between races in other sepsis quality measures or adjusted mortality.

We reviewed studies that analyzed cysticercosis (CC), neurocysticercosis (NCC) and epilepsy across Latin America, Asia and Sub-Saharan Africa, to estimate the odds ratio and etiologic fraction of epilepsy due to CC in tropical regions. We conducted a systematic review of the literature on cysticercosis and epilepsy in the tropics, collecting data from case-control and cross-sectional studies. Exposure criteria for CC included one or more of the following: serum ELISA or EITB positivity, presence of subcutaneous cysts (both not verified and unverified by histology), histology consistent with calcified cysts, and brain CT scan consistent with NCC. A common odds-ratio was then estimated using meta-analysis. 37 studies from 23 countries were included (n = 24,646 subjects, 14,934 with epilepsy and 9,712 without epilepsy). Of these, 29 were case-control (14 matched). The association between CC and epilepsy was significant in 19 scientific articles. Odds ratios ranged from 0.2 to 25.4 (a posteriori power 4.5-100%) and the common odds ratio was 2.7 (95% CI 2.1-3.6, p <0.001). Three subgroup analyses performed gave odds ratios as: 2.2 (EITB-based studies), 3.2 (CT-based studies), 1.9 (neurologist-confirmed epilepsy; door-to-door survey and at least one matched control per case). Etiologic fraction was estimated to be 63% in the exposed group among the population. Despite differences in findings, this meta-analysis suggests that cysticercosis is a significant contributor to late-onset epilepsy in tropical regions around the world, and its impact may vary depending on transmission intensity.

Study objective: To investigate the risk of stillbirth, neonatal death, and lethal congenital anomaly among babies of mothers living close to incinerators and crematoriums in Cumbria, north west England, 1956–93. Design: Retrospective cohort study. Logistic regression was used to investigate the risk of each outcome in relation to proximity at birth to incinerators and crematoriums, adjusting for social class, year of birth, birth order, and multiple births. Continuous odds ratios for trend with proximity to sites were estimated. Setting: All 3234 stillbirths, 2663 neonatal deaths, and 1569 lethal congenital anomalies among the 244 758 births to mothers living in Cumbria, 1956–1993. Main results: After adjustment for social class, year of birth, birth order, and multiple births, there was an increased risk of lethal congenital anomaly, in particular spina bifida (odds ratio 1.17, 95% CI: 1.07 to 1.28) and heart defects (odds ratio 1.12, 95% CI: 1.03 to 1.22) around incinerators and an increased risk of stillbirth (odds ratio 1.04, 95% CI: 1.01 to 1.07) and anencephalus (odds ratio 1.05, 95% CI: 1.00 to 1.10) around crematoriums. Conclusions: The authors cannot infer a causal effect from the statistical associations reported in this study. However, as there are few published studies with which to compare our results, the risk of spina bifida, heart defects, stillbirth, and anencephalus in relation to proximity to incinerators and crematoriums should be investigated further, in particular because of the increased use of incineration as a method of waste disposal.

Increased lung cancer risks among hairdressers were observed in large registry-based cohort studies from Scandinavia, but these studies could not adjust for smoking. Our objective was to evaluate the lung cancer risk among hairdressers while adjusting for smoking and other confounders in a pooled database of 16 case-control studies conducted in Europe, Canada, China, and New Zealand between 1985 and 2010 (the Pooled Analysis of Case-Control Studies on the Joint Effects of Occupational Carcinogens in the Development of Lung Cancer). Lifetime occupational and smoking information was collected through interviews with 19,369 cases of lung cancer and 23,674 matched population or hospital controls. Overall, 170 cases and 167 controls had ever worked as hairdresser or barber. The odds ratios for lung cancer in women were 1.65 (95% confidence interval (CI): 1.16, 2.35) without adjustment for smoking and 1.12 (95% CI: 0.75, 1.68) with adjustment for smoking; however, women employed before 1954 also experienced an increased lung cancer risk after adjustment for smoking (odds ratio = 2.66, 95% CI: 1.09, 6.47). The odds ratios in male hairdressers/barbers were generally not elevated, except for an increased odds ratio for adenocarcinoma in long-term barbers (odds ratio = 2.20, 95% CI: 1.02, 4.77). Our results suggest that the increased lung cancer risks among hairdressers are due to their smoking behavior; single elevated risk estimates should be interpreted with caution and need replication in other studies.

Hyperinsulinemia and insulin resistance are both associated with the development of Type 2 Diabetes and other pathologies; however, the influence of parental history of Type 2 diabetes (PH-T2D) has yet to be investigated. Therefore, this study was conducted to determine the effect of PH-T2D has on the risk of developing hyperinsulinemia and IR. 1092 subjects (703 non-pregnant females and 389 males) were enrolled for a cross-sectional study. Clinical and biochemical parameters were collected. Subjects were allocated according to their PH-T2D: no parents, one parent, or both parents. Insulin resistance was calculated using the HOMA1 equation (HOMA1-IR). Logistic regression was used to determine the association (odds ratio) between PH-T2D and hyperinsulinemia or insulin resistance. Increasing degrees of PH-T2D were associated with significant increases in fasting plasma glucose, insulin, and HOMA1-IR (p <0.05). Subjects having one or both parents were associated with an increase risk of developing hyperinsulinemia (odds ratio=1.53, 95%CI: 1.12-2.09, and odds ratio=1.92, 95%CI: 1.21-3.06, respectively) and insulin resistance (odds ratio=1.47, 95%CI: 1.08-2.00 and odds ratio=1.77, 95%CI: 1.09-2.87, respectively), when adjusting for age, sex, BMI, fasting plasma glucose, and triglycerides. The presences of PH-T2D significantly increased the risk of developing hyperinsulinemia and insulin resistance. Copyright © 2017 Diabetes India. Published by Elsevier Ltd. All rights reserved.

Artemisinin-based combination treatments (ACTs) are the recommended first-line antimalarials globally, but their influence on the risk factors associated with gametocyte carriage has had little evaluation in endemic areas. The risk factors associated with gametocytaemia at presentation and after ACTs were evaluated in 835 children assigned to artesunate, artesunate-amodiaquine, artesunate-mefloquine or artemether-lumefantrine. Gametocyte carriage at enrolment was 8.4%. During follow-up, 24 patients (2.8%) developed gametocytaemia, which in 83% (20 patients) had developed by day 7 following treatment. In a multiple regression model, 2 factors were independent risk factors for the presence of gametocytaemia at enrolment, namely age <3 years (adjusted odds ratio 2.03, 95% confidence interval 1.01-4.05; p = 0.04) and enrolment before 2009 (adjusted odds ratio 4.2, 95% confidence interval 2.09-8.44; p < 0.001). Haematocrit <25% and parasitaemia <50,000/μl blood were associated with an increased risk of gametocytaemia. Following treatment, 3 factors were independent risk factors for gametocytaemia, namely gametocytaemia at enrolment (adjusted odds ratio 46.39, 95% confidence interval 22.3-96.46; p < 0.0001) and treatment with artesunate (adjusted odds ratio 6.74, 95% confidence interval 1.79-25.27; p = 0.005) or artesunate-mefloquine (adjusted odds ratio 9.66, 95% confidence interval 2.87-32.46; p < 0.0.0001) relative to other ACTs. ACTs modified the risk factors associated with gametocyte carriage after use. Copyright © 2012 S. Karger AG, Basel.

Epiretinal membranes (ERM) are macular disorders leading to loss of vision and metamorphopsia. Vitrectomy with membrane peeling displays the gold standard of care. Aim of this study was to assess risk factors for postoperative intraretinal cystoid changes in a study population randomized for balanced salt solution and air-tamponade at the end of surgery. A prospective randomized study, including 69 eyes with idiopathic ERM. Standard 23-gauge three-port pars plana vitrectomy with membrane peeling, using intraoperative optical coherence tomography (OCT), was performed. Randomization for BSS and air-tamponade was performed prior to surgery. Best-corrected visual acuity improved from 32.9 letters to 45.1 letters 3 months after surgery. Presence of preoperative intraretinal cystoid changes was found to be the only risk factor for presence of postoperative intraretinal cystoid changes 3 months after surgery (p = 0.01; odds ratio: 8.0). Other possible risk factors such as combined phacoemulsification with 23G-ppv and membrane peeling (p = 0.16; odds ratio: 2.4), intraoperative subfoveal hyporeflective zones (p = 0.23; odds ratio: 2.6), age over 70 years (p = 0.29; odds ratio: 0.5) and air-tamponade (p = 0.59; odds ratio: 1.5) were not found to be significant. There is strong evidence that preoperative intraretinal cystoid changes lead to smaller benefit from surgery. © 2018 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

To ascertain complications associated with high-dose stimulant therapy in patients with narcolepsy or idiopathic hypersomnia. Case-control, retrospective chart review. Sleep center in an academic hospital. 116 patients with narcolepsy or idiopathic hypersomnia were individually matched by sex, diagnosis, age of onset, and duration of follow-up from both onset and diagnosis. Members of the high-dose group (n = 58) had received at least 1 stimulant at a dosage > or = 120% of the maximum recommended by the American Academy of Sleep Medicine Standards of Practice Committee. The standard-dose control group (n = 58) had received stimulants at a dosage < or = 100% of the American Academy of Sleep Medicine guidelines. N/A. The prevalence of psychosis (odds ratio = 12.0 [1.6-92.0]), alcohol or polysubstance misuse (odds ratio = 4.3 [1.2-15.2]), and psychiatric hospitalization (odds ratio = 3.2 [1.1-10.0]) was significantly increased in the high-dose group. More high-dose patients also experienced tachyarrhythmias (odds ratio = 3.3 [0.92-12.1] and anorexia or weight loss (odds ratio = 11.0 [1.4-85.2]). The frequency of physician-diagnosed depression, drug-seeking and suicide-related behaviors, hypertension, and cardiovascular disease did not differ significantly between the groups. This study demonstrated a significantly higher occurrence of psychosis, substance misuse, and psychiatric hospitalizations in patients using high-dose stimulants compared to those using standard doses. Tachyarrhythmias and anorexia or weight loss were also more common in this group as compared with controls. Clinicians should be very cautious in prescribing dosages that exceed maximum guidelines.

Polymorphisms in the gene encoding the glutathione S-transferase (GST) pi metabolizing enzyme have previously been associated with susceptibility to various cancers. In this study, the importance of GSTP1 genotypes as determinants of risk for oral cancer was assessed by examining the prevalence of GSTP1 alleles in 157 incident oral cancer cases and 260 non-cancer control individuals frequency-matched by race, sex, and age at diagnosis (+/- 5 years). The GSTP1*A, GSTP1*B, GSTP1*C, and GSTP1*D alleles were elucidated by polymerase chain reaction-restriction fragment length polymorphism analysis of polymorphisms present in codons 105 (isoleucine:valine) and 114 (alanine:valine) of the GSTP1 gene. Increased risk for oral cancer was observed in individuals who were homozygous for any combination of GSTP1 polymorphic alleles (i.e. *B, *C, and/or *D alleles; odds ratio = 2.4, 95% confidence interval = 1.2-4.8). Similar risk was observed in both Caucasians (odds ratio = 2.6, 95% confidence interval = 1.1-6.2) and African-Americans (odds ratio = 2.3, 95% CI = 0.68-7.5). A greater risk was observed in individuals with the GSTP1 (Var/Var) genotype who were exposed to low levels of smoking (i.e. < or = 20 pack-years [py], odds ratio = 3.4, 95% confidence interval = 1.1-11) than among heavier smokers (i.e. > 20 pack-years [py], odds ratio = 1.4, 95% confidence interval = 0.48-4.0). These results suggest that GSTP1 genotype may play a role in risk for oral cancer particularly among lighter smokers.

Despite the recent flourishing of mediation analysis techniques, many modern approaches are difficult to implement or applicable to only a restricted range of regression models. This report provides practical guidance for implementing a new technique utilizing inverse odds ratio weighting (IORW) to estimate natural direct and indirect effects for mediation analyses. IORW takes advantage of the odds ratio's invariance property and condenses information on the odds ratio for the relationship between the exposure (treatment) and multiple mediators, conditional on covariates, by regressing exposure on mediators and covariates. The inverse of the covariate-adjusted exposure-mediator odds ratio association is used to weight the primary analytical regression of the outcome on treatment. The treatment coefficient in such a weighted regression estimates the natural direct effect of treatment on the outcome, and indirect effects are identified by subtracting direct effects from total effects. Weighting renders treatment and mediators independent, thereby deactivating indirect pathways of the mediators. This new mediation technique accommodates multiple discrete or continuous mediators. IORW is easily implemented and is appropriate for any standard regression model, including quantile regression and survival analysis. An empirical example is given using data from the Moving to Opportunity (1994-2002) experiment, testing whether neighborhood context mediated the effects of a housing voucher program on obesity.

Gastro-oesophageal reflux symptoms are usually reported by patients with obesity and metabolic syndrome. Aim of this study was to assess the prevalence and clinical characteristics of gastro-oesophageal reflux symptoms in subjects with non-alcoholic fatty liver disease. Cross-sectional, case-control study of 185 consecutive patients with non-alcoholic fatty liver disease and an age- and sex-matched control group of 112 healthy volunteers. Participants were interviewed with the aid of a previously validated questionnaire to assess lifestyle and reflux symptoms in the 3 months preceding enrolment. Odds ratios were determined before and after adjustment for body mass index, increased waist circumference, physical activity, metabolic syndrome and proton pump inhibitors and/or antiacid medication. The prevalence of heartburn and/or regurgitation and of at least one of gastro-oesophageal reflux symptoms was significantly higher in the non-alcoholic fatty liver disease group. Non-alcoholic fatty liver disease subjects were associated to higher prevalence of heartburn (adjusted odds ratios: 2.17, 95% confidence intervals: 1.16-4.04), regurgitation (adjusted odds ratios: 2.61, 95% confidence intervals: 1.24-5.48) and belching (adjusted odds ratios: 2.01, 95% confidence intervals: 1.12-3.59) and had higher prevalence of at least one GER symptom (adjusted odds ratios: 3.34, 95% confidence intervals: 1.76-6.36). Non-alcoholic fatty liver disease is associated with a higher prevalence of gastro-oesophageal reflux symptoms. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Age-related eye disease is often considered part of natural aging. Lack of awareness of eye conditions can result in missed treatment. We investigated the rates of awareness of cataract and age-related macular degeneration, the most common age-related eye-diseases, and the associated factors among elderly Koreans. We identified 7,403 study subjects (≥40 years old) with cataract or age-related macular degeneration based on ophthalmic examination results during the 5th Korean National Health and Nutrition Examination Survey conducted between 2010 and 2012. We assessed whether patients were aware of their eye condition based on a previous diagnosis by a physician. The average awareness rate over the 3-year study period was 23.69% in subjects with cataract and 1.45% in subjects with age-related macular degeneration. Logistic regression analysis showed that patients with cataract were more likely to recognize their condition if they had myopia (odds ratio, 2.08), hyperopia (odds ratio, 1.33), family history of eye disease (odds ratio, 1.44), or a past eye examination (odds ratio, 4.07-29.10). The presence of diabetes mellitus was also a significant predictor of patient awareness of cataract (odds ratio, 1.88). Poor patient recognition of eye disease among the Korean elderly highlights the seriousness of this potential public health problem in our aging society. Pre-existing eye-related conditions and diabetes were significant predictors of awareness; therefore, patients in frequent contact with their doctors have a greater chance of detecting eye disease. © 2017 The Korean Ophthalmological Society

This study examined age differences in daily life events related to different types of social goals based on the socioemotional selectivity theory (SST), and determined whether the positivity effect existed in the context of social goals in older adults’ daily lives. Over a course of 14 days, 49 older adults and 36 younger adults wrote about up to three life events daily and rated the valence of each event. The findings indicated that (1) although both older and younger adults recorded events related to both emotional and knowledge-acquisition goals, the odds ratio for reporting a higher number of events related to emotional goals compared to the number of events related to knowledge-acquisition goals was 2.12 times higher in older adults than that observed in younger adults. (2) Considering the number of events, there was an age-related positivity effect only for knowledge-related goals, and (3) older adults’ ratings for events related to emotional and knowledge-acquisition goals were significantly more positive compared to those observed in younger adults. These findings supported the SST, and to some extent, the positivity effect was demonstrated in the context of social goals. PMID:28979227

American Indian women in the Northern Plains have a high incidence of cervical cancer. We assessed attitudes on vaccination against human papillomavirus (HPV) in this population. In partnership with two tribal communities, from 2007 to 2009, we surveyed women 18 to 65 years old attending two reservation clinics (n = 118 and n = 76) and an urban clinic in the same region serving primarily White women (n = 158) on HPV knowledge, vaccine familiarity, and willingness to vaccinate children against HPV. We used chi-square tests and binary logistic regression to compare groups and identify correlates of willingness to vaccinate. American Indian women were less knowledgeable about HPV than White women (p < .001), especially its role in cervical cancer. Willingness to vaccinate children was differentially distributed across the three clinic samples (p < .001), but this association did not persist after adjusting for demographics and HPV knowledge. Among all samples, more correct answers to HPV knowledge questions was the only factor positively correlated with willingness to vaccinate (odds ratios = 1.2-1.5; p < .00-.05). These findings underscore the importance of locally relevant educational interventions to increase HPV vaccination rates among American Indian women.

Lack of global health knowledge places immigrants at risk of iatrogenic morbidity. Although global health education programs have grown in popularity, measurable impact is lacking. We previously surveyed 363 physicians in training across 15 programs in four countries in 2004 regarding basic parasite knowledge and recognition of Strongyloides risk through a theoretical case scenario. In 2005, the University of Minnesota implemented a formal global health training program (GHP). In 2009, the identical survey was repeated. Strongyloidiasis recognition increased from 11.1% (19/171) in 2004 to 39.4% (50/127) in 2009 (P < 0.001). Trainees participating in formal didactic and interactive curriculum had superior recognition (77% versus 29%; P < 0.001). In a multivariate model of GHP training activities, participation in an American Society of Tropical Medicine and Hygiene-accredited global health certificate course increased recognition (odds ratio = 9.5, 95% confidence interval = 2.5–36, P = 0.001), whereas participation in international electives alone did not (P = 0.9). A formal GHP curriculum was associated with improved knowledge regarding common parasitic infections and the risk of iatrogenic morbidity and mortality due to strongyloidiasis. PMID:21896795

Butchers have a huge role in prevention of meat-borne diseases and illness. Hence, this study was conducted to ascertain factors associated with meat hygiene among the butchers. A cross-sectional study was conducted among goat and poultry butchers. None of the butchers fall into "adequate" knowledge and "good" practice category. Butchers who had no side job other than butchering (adjusted odds ratio [aOR] = 3.04, CI = 1.11-8.33), had secondary or higher education (aOR = 3.17, CI = 2.60-14.72), greater workload (aOR = 5.45, CI = 1.01-29.57), and whose shop were closed shop (aOR = 3.33, CI = 1.10-10.38) were more likely to have fair knowledge. Butchers whose shop were temporarily constructed close shop (aOR = 3.07, CI = 1.04-9.06), permanently constructed close shop (aOR = 23.56, CI = 1.91-291.11), and whose ethnicity was Brahmin/Chhetri (aOR = 3.39, CI = 1.10-10.46) were more likely to have satisfactory practices. Despite regular handling of meat, butchers had lack of knowledge and practice on meat hygiene.

Essential hypertension (EH) is a complex disease in which physiological, environmental, and genetic factors are involved in its genesis. The genetic variant of the alpha-adducin gene (ADD1) has been described as a risk factor for EH, but with controversial results.The objective of this study was to evaluate the association of ADD1 (Gly460Trp) gene polymorphism with the EH risk in a population from Madeira Island.A case-control study with 1614 individuals of Caucasian origin was performed, including 817 individuals with EH and 797 controls. Cases and controls were matched for sex and age, by frequency-matching method. All participants collected blood for biochemical and genotypic analysis for the Gly460Trp polymorphism. We further investigated which variables were independently associated to EH, and, consequently, analyzed their interactions.In our study, we found a significant association between the ADD1 gene polymorphism and EH (odds ratio 2.484, P = .01). This association remained statistically significant after the multivariate analysis (odds ratio 2.548, P = .02).The ADD1 Gly460Trp gene polymorphism is significantly and independently associated with EH risk in our population. The knowledge of genetic polymorphisms associated with EH is of paramount importance because it leads to a better understanding of the etiology and pathophysiology of this pathology.

Much of our knowledge of risk factors for falls comes from studies of the general population. The aim of this study was to estimate the risk of falling associated with commonly accepted and stroke-specific factors in a home-dwelling stroke population. This study included an analysis of prospective fall reports in 124 women with confirmed stroke over 1 year. Variables relating to physical and mental health, history of falls, stroke symptoms, self-reported difficulties in activities of daily living, and physical performance tests were collected during home assessments. Risk factors for falling commonly reported in the general population, including performance tests of balance, incontinence, previous falls, and sedative/hypnotic medications, did not predict falls in multivariate analyses. Frequent balance problems while dressing were the strongest risk factor for falls (odds ratio, 7.0). Residual balance, dizziness, or spinning stroke symptoms were also a strong risk factor for falling (odds ratio, 5.2). Residual motor symptoms were not associated with an increased risk of falling. Interventions to reduce the frequency of balance problems during complex tasks may play a significant role in reducing falls in stroke. Clinicians should be aware of the increased risk of falling in women with residual balance, dizziness, or spinning stroke symptoms and recognize that risk assessments developed for use in the general population may not be appropriate for stroke patients.

Depression has been linked to the overall diet using both exploratory and pre-defined methods. However, neither of these methods incorporates specific knowledge on nutrient-disease associations. The aim of the present study was to empirically identify dietary patterns using reduced rank regression and to examine their relations to depressive symptoms. Participants were 2006 Japanese employees aged 19-69 years. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Diet was assessed using a validated, self-administered diet history questionnaire. Dietary patterns were extracted by reduced rank regression with 6 depression-related nutrients as response variables. Logistic regression was used to estimate odds ratios of depressive symptoms adjusted for potential confounders. A dietary pattern characterized by a high intake of vegetables, mushrooms, seaweeds, soybean products, green tea, potatoes, fruits, and small fish with bones and a low intake of rice was associated with fewer depressive symptoms. The multivariable-adjusted odds ratios of having depressive symptoms were 0.62 (95% confidence interval, 0.48-0.81) in the highest versus lowest tertiles of dietary score. Results suggest that adherence to a diet rich in vegetables, fruits, and typical Japanese foods, including mushrooms, seaweeds, soybean products, and green tea, is associated with a lower probability of having depressive symptoms.

To investigate a possible link between sociodemographic factors, the perception of smoking habits at school and smoking status of Italian adolescents attending secondary school. The study was a cross-sectional study. An anonymous online survey was employed to gather information on age, gender, smoking status and to examine the perception of smoking behaviour on the school premises. Chi-squared and Kruskal-Wallis tests were performed for the univariate analysis and logistic and multinomial regressions for the multivariate analysis. The statistical analyses included 1889 students. Univariate analysis showed significant differences concerning knowledge between smoker and non-smoker concerning the harmfulness of smoking (P < 0.001). According to the multivariate analysis smokers had a higher perception of teacher, principal or janitor smoking at school (odds ratio: 1.54 [95% confidence interval 1.26-1.89]). Students older than 19 years most often begin smoking because their friends smoke compared with younger students (adjusted odds ratio: 1.18 [95% confidence interval 0.48-2.89]). School environment and behaviour of role models play a crucial part in student smoking. To prevent and reduce youth tobacco smoking, not merely the presence of preventive measures is important but greater attention needs to be placed on the enforcement of smoking policies.

To evaluate changes in the role of academics and the sources of funding for the medical research cited most frequently over the past decade. Database analysis. Web of Knowledge database. For each year from 1994 to 2003, articles in the domain of clinical medicine that had been cited most often by the end of 2004 were identified. Changes in authors' affiliations and funding sources were evaluated. Of the 289 frequently cited articles, most had at least one author with a university (76%) or hospital (57%) affiliation, and the proportion of articles with each type of affiliation was constant over time. Government or public funding was most common (60% of articles), followed by industry (36%). The proportion of most frequently cited articles funded by industry increased over time (odds ratio 1.17 per year, P = 0.001) and was equal to the proportion funded by government or public sources by 2001. 65 of the 77 most cited randomised controlled trials received funding from industry, and the proportion increased significantly over time (odds ratio 1.59 per year, P = 0.003). 18 of the 32 most cited trials published after 1999 were funded by industry alone. Academic affiliations remain prominent among the authors of the most frequently cited medical research. Such research is increasingly funded by industry, often exclusively so. Academics may be losing control of the clinical research agenda.

The aim of this study was to assess the knowledge of Omani adults regarding conventional coronary heart disease (CHD) risk factors and to identify demographic variables associated with these knowledge levels. This descriptive cross-sectional pilot study was carried out among a convenience sample of 130 adults attending a health awareness fair held in a local shopping mall in Muscat, Oman, in November 2012. A modified version of the Heart Disease Facts Questionnaire in both English and Arabic was used to assess knowledge of CHD risk factors. Scores were calculated by summing the correct answers for each item (range: 0-21). Inadequate knowledge was indicated by a mean score of <70%. Descriptive and multivariate logistic regression analyses were performed to establish the participants' knowledge levels and identify associated demographic variables. A total of 114 subjects participated in the study (response rate: 87.7%). Of these, 69 participants (60.5%) had inadequate mean CHD knowledge scores. Knowledge of CHD risk factors was significantly associated with body mass index (odds ratio [OR] = 0.739; P = 0.023), marital status (OR = 0.057; P = 0.036) and education level (OR = 9.243; P = 0.006). Low knowledge levels of CHD risk factors were observed among the studied community sample in Oman; this is likely to limit the participants' ability to engage in preventative practices. These findings support the need for education programmes to enhance awareness of risk factors and prevention of CHD in Oman.

Our aim was to study the impact of depressive disorders on work disability to discover the determinants of depression for work disability in the European countries. The sample was composed of 31,126 individuals from 29 countries included in the 2002 World Health Survey of the World Health Organization. National representative samples of countries from all regions of Europe and with different levels of economic development and health coverage were selected. Estimates of people not working because of ill health did not differ among European countries in relation to levels of economic development or health coverage. Significant determinants of people with diagnosis of depression not working because of ill health (reference category) versus working were age (odds ratio = 0.97), female sex (odds ratio = 1.71), education (odds ratio = 1.11), marital status (being unmarried indicating less probability), lowest income level, and comorbidity with angina pectoris (odds ratio = 0.51). Moreover, according to previous studies, we found some determinants (comorbidity with other diseases, young age, and unemployment) impacting on health status. Depression is a substantial cause of work disability and it is a complex phenomenon that involves many variables. Investigation into this relationship should improve, focusing on the role of determinants.

An acute health effect of people living near the petrochemical industrial estate in Thailand was assessed using a panel study design. The populations in communities near the petrochemical industrial estates were recruited. The daily air pollutant concentrations, daily percentage of respiratory and other health symptoms reported were collected for 63 days. The effect of air pollutants to reported symptoms of people were estimated by adjusted odds ratios and 95% confidence interval using binary logistic regression. The significant associations were found with the adjusted odds ratios of 38.01 for wheezing, 18.63 for shortness of breath, 4.30 for eye irritation and 3.58 for dizziness for total volatile organic compounds (Total VOCs). The adjusted odds ratio for carbon monoxide (CO2) was 7.71 for cough, 4.55 for eye irritation and 3.53 for weakness and the adjusted odds ratio for ozone (O3) was 1.02 for nose congestion, sore throat and 1.05 for phlegm. The results showed that the people living near petrochemical industrial estate had acute adverse health effects, shortness of breath, eye irritation, dizziness, cough, nose congestion, sore throat, phlegm and weakness from exposure to industrial air pollutants.

Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Several patients´ or procedure related risk factors for post-ERCP pancreatitis (PEP) have been suggested. The aim of this study was to validate the risk factors for PEP in a high-volume center. All patients undergoing first time ERCP at a tertiary referral center between December 2010 and October 2013 were retrospectively included. PEP was defined according to the Atlanta Classification. 344 patients were included in the final analysis. The risk to develop PEP was increased in patients with chronic pancreatitis (odds ratio 3.7) and after inadvertent cannulation of the pancreatic duct (odds ratio 2.2), which occurred in 26.5% of the patients. Inadvertent cannulation occurred significantly more frequently in patients with difficult cannulation of the papilla duodeni major (odds ratio 12.7; p<0.001). ERCP on call was associated with an increased risk for difficult cannulation (odds ratio 3.0). Inadvertent cannulation of the pancreatic duct is a procedure related risk factor for PEP. Measurements on preventing inadvertent cannulation of the pancreatic duct should be established and studies on prophylactic measurements should focus particularly on patients with inadvertent cannulation of the pancreatic duct.

Bendectin and human congenital malformations.

The relationship between Bendectin exposure during the first trimester of pregnancy and the occurrence of congenital malformations was prospectively studied in 31,564 newborns registered in the Northern California Kaiser Permanente Birth Defects Study. The odds ratio for any major malformation and Bendectin use was 1.0 (95% confidence interval 0.8-1.4). There were 58 categories of congenital malformations; three of them were statistically associated with Bendectin exposure (microcephaly--odds ratio = 5.3, 95% confidence interval = 1.8-15.6; congenital cataract--odds ratio = 5.3, 95% confidence interval = 1.2-24.3; lung malformations (ICD-8 codes 484.4-484.8)--odds ratio = 4.6, 95% confidence interval = 1.9-10.9). This is exactly the number of associations that would be expected by chance. An independent study (the Collaborative Perinatal Project) was used to determine whether vomiting during pregnancy in the absence of Bendectin use was associated with these three malformations. Two of the three (microcephaly and cataract) had strong positive associations with vomiting in the absence of Bendectin use. We conclude that there is no increase in the overall rate of major malformations after exposure to Bendectin and that the three associations found between Bendectin and individual malformations are unlikely to be causal.

To compare knowledge and attitudes of human papillomavirus (HPV) and the vaccine between different cultures of African descent. A cross-sectional survey of 555 African-Americans and Afro-Caribbeans residing in the US and the Bahamas (BHM) was conducted. General knowledge about HPV and the HPV vaccine differed between the two countries significantly. Bahamian respondents were less likely to have higher numbers of correct knowledge answers when compared to Americans (Adjusted Odds Ratio [Adj. OR] 0.47, 95% Confidence Interval [CI] 0.30-0.75). Older age, regardless of location, was also associated with answering fewer questions correctly (Adj. OR 0.61, 95% CI 0.40-0.92). Attitudes related to HPV vaccination were similar between the US and BHM, but nearly 80% of BHM respondents felt that children should not be able to receive the vaccine without parental consent compared to 57% of American respondents. Grave lack of knowledge, safety and cost concerns, and influence of parental restrictions may negatively impact vaccine uptake among African-American and Afro-Caribbean persons. Interventions to increase the vaccine uptake in the Caribbean must include medical provider and parental involvement. Effective strategies for education and increasing vaccine uptake in BHM are crucial for decreasing cervical cancer burden in the Caribbean.

Although some sociologists have suggested that Japanese Americans quickly assimilated into mainstream America, scholars of Japanese America have highlighted the heightened exclusion that the group experienced. This study tracked historical shifts in the exclusion level of Japanese and Japanese Americans in the United States surrounding World War II with homogamy and intermarriage with Whites for the prewar (1930-1940) and resettlement (1946-1966) marriage cohorts. The authors applied log-linear models to census microsamples (N = 1,590,416) to estimate the odds ratios of homogamy versus intermarriage. The unadjusted odds ratios of Japanese Americans declined between cohorts and appeared to be consistent with the assimilation hypothesis. Once compositional influences and educational pairing patterns were adjusted, however, the odds ratios increased and supported the heightened exclusion hypothesis.

Past research suggests more variation in sexual attraction in Autism Spectrum Disorder (ASD) using clinical samples. This study utilised a population representative group of 14/15 year olds from the Longitudinal Study of Australian Children. Ninety-four adolescents (73 males, 21 females) with ASD and 3454 (1685 males, 1675 females) without self-reported on sexual attraction and past sexual relationships. Females with ASD reported lower rates of heterosexual preference (adjusted odds ratio: 0.14, p < .001), higher rates of bisexuality (adjusted odds ratio: 6.05, p < .001) and uncertainty in attraction (adjusted odds ratio: 10.44, p < .001) compared with non-ASD females. ASD males reported fewer prior boyfriends/girlfriends. Findings confirm female adolescents with ASD have differences in sexual attraction compared with non-ASD females.

To determine the value of two abdominal aortic atherosclerosis measurements at magnetic resonance (MR) imaging for predicting future cardiovascular events. This study was approved by the institutional review board and complied with HIPAA regulations. The study consisted of 2122 participants from the multiethnic, population-based Dallas Heart Study who underwent abdominal aortic MR imaging at 1.5 T. Aortic atherosclerosis was measured by quantifying mean aortic wall thickness (MAWT) and aortic plaque burden. Participants were monitored for cardiovascular death, nonfatal cardiac events, and nonfatal extracardiac vascular events over a mean period of 7.8 years ± 1.5 (standard deviation [SD]). Cox proportional hazards regression was used to assess independent associations of aortic atherosclerosis and cardiovascular events. Increasing MAWT was positively associated with male sex (odds ratio, 3.66; P < .0001), current smoking (odds ratio, 2.53; P < .0001), 10-year increase in age (odds ratio, 2.24; P < .0001), and hypertension (odds ratio, 1.66; P = .0001). A total of 143 participants (6.7%) experienced a cardiovascular event. MAWT conferred an increased risk for composite events (hazard ratio, 1.28 per 1 SD; P = .001). Aortic plaque was not associated with increased risk for composite events. Increasing MAWT and aortic plaque burden both conferred an increased risk for nonfatal extracardiac events (hazard ratio of 1.52 per 1 SD [P < .001] and hazard ratio of 1.46 per 1 SD [P = .03], respectively). MR imaging measures of aortic atherosclerosis are predictive of future adverse cardiovascular events. © RSNA, 2013.

Background and objectives Current measures for predicting renal functional decline in patients with type 2 diabetes with preserved renal function are unsatisfactory, and multiple markers assessing various biologic axes may improve prediction. We examined the association of four biomarker-to-creatinine ratio levels (monocyte chemotactic protein-1, IL-18, kidney injury molecule-1, and YKL-40) with renal outcome. Design, setting, participants, & measurements We used a nested case-control design in the Action to Control Cardiovascular Disease Trial by matching 190 participants with ≥40% sustained eGFR decline over the 5-year follow-up period to 190 participants with ≤10% eGFR decline in a 1:1 fashion on key characteristics (age within 5 years, sex, race, baseline albumin-to-creatinine ratio within 20 μg/mg, and baseline eGFR within 10 ml/min per 1.73 m2), with ≤10% decline. We used a Mesoscale Multiplex Platform and measured biomarkers in baseline and 24-month specimens, and we examined biomarker associations with outcome using conditional logistic regression. Results Baseline and 24-month levels of monocyte chemotactic protein-1-to-creatinine ratio levels were higher for cases versus controls. The highest quartile of baseline monocyte chemotactic protein-1-to-creatinine ratio had fivefold greater odds, and each log increment had 2.27-fold higher odds for outcome (odds ratio, 5.27; 95% confidence interval, 2.19 to 12.71 and odds ratio, 2.27; 95% confidence interval, 1.44 to 3.58, respectively). IL-18-to-creatinine ratio, kidney injury molecule-1-to-creatinine ratio, and YKL-40-to-creatinine ratio were not consistently associated with outcome. C statistic for traditional predictors of eGFR decline was 0.70, which improved significantly to 0.74 with monocyte chemotactic protein-1-to-creatinine ratio. Conclusions Urinary monocyte chemotactic protein-1-to-creatinine ratio concentrations were strongly associated with sustained renal decline in patients with type 2 diabetes with preserved renal function.

Introduction The oral part of European Diploma in Intensive Care diploma examinations changed in 2013 into an objective structured clinical examination-type exam. This step was undertaken to provide a fair and reproducible clinical exam. All candidates face identical questions with predefined correct answers simultaneously in seven high throughput exam centres on the same day. We describe the factors that are associated with success in part 2 European Diploma in Intensive Care exam. Methods We prospectively collected self-reported data from all candidates sitting European Diploma in Intensive Care part 2 in 2015, namely demographics, professional background and attendance to a European Diploma in Intensive Care part 2 or generic objective structured clinical examination preparatory courses. After testing association with success (with cutoff at p < 0.10) and co-linearity of these factors as independent variables, we performed a multivariate logistical analysis, with binary exam outcome (pass/fail) as the dependent variable. Structural equation modelling was used to gain further insight into relations among determinants of success in the oral part of the European Diploma in Intensive Care. Results Out of 427 candidates sitting the exam, completed data from 341 (80%) were available for analysis. The following candidates' factors were associated with increased chance of success: English as native language (odds ratio 4.3 (95% CI 1.7–10.7)), use of Patient-centred Acute Care Training e-learning programme module (odds ratios 2.0 (1.2–3.3)), working in an EU country (odds ratios 2.5 (1.5–4.3)), and better results in the written part of the European Diploma in Intensive Care (for each additional SD of 6.1 points odds ratios 1.9 (1.4–2.4)). Chance of success in the European Diploma in Intensive Care 2 decreased with increased candidates ‘age (for each additional SD of 5.5 years odds ratios 0.67 (0.51–0.87)). Exam centres (7 in total) could be clustered into 3 groups with similar success rates. There were significant differences in exam outcomes among these 3 groups of exam centres even after adjustment to known candidates' factors (G1 vs G2 odds ratios 2.4 (1.4–4.1); G1 vs G3 odds ratios 9.7 (4.0–23.1) and G2 vs G3 odds ratios 3.9 (1.7–9.2)). A short data collection period (only one year) and 20% of missing candidates' data are the main limitations of this study. Conclusions Younger age, English as native language, better results in written part of the exam, working at a European country and the use of PACT for preparation, were factors associated with success in the oral part of the European Diploma in Intensive Care exam. Despite the limitations of this study, the differences in outcome among the exam centres will need further investigation. PMID:29123559

Randomized trials of hypertension have seldom examined heterogeneity in response to treatments over time and the implications for cardiovascular outcomes. Understanding this heterogeneity, however, is a necessary step toward personalizing antihypertensive therapy. We applied trajectory-based modeling to data on 39 763 study participants of the ALLHAT (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial) to identify distinct patterns of systolic blood pressure (SBP) response to randomized medications during the first 6 months of the trial. Two trajectory patterns were identified: immediate responders (85.5%), on average, had a decreasing SBP, whereas nonimmediate responders (14.5%), on average, had an initially increasing SBP followed by a decrease. Compared with those randomized to chlorthalidone, participants randomized to amlodipine (odds ratio, 1.20; 95% confidence interval [CI], 1.10-1.31), lisinopril (odds ratio, 1.88; 95% CI, 1.73-2.03), and doxazosin (odds ratio, 1.65; 95% CI, 1.52-1.78) had higher adjusted odds ratios associated with being a nonimmediate responder (versus immediate responder). After multivariable adjustment, nonimmediate responders had a higher hazard ratio of stroke (hazard ratio, 1.49; 95% CI, 1.21-1.84), combined cardiovascular disease (hazard ratio, 1.21; 95% CI, 1.11-1.31), and heart failure (hazard ratio, 1.48; 95% CI, 1.24-1.78) during follow-up between 6 months and 2 years. The SBP response trajectories provided superior discrimination for predicting downstream adverse cardiovascular events than classification based on difference in SBP between the first 2 measurements, SBP at 6 months, and average SBP during the first 6 months. Our findings demonstrate heterogeneity in response to antihypertensive therapies and show that chlorthalidone is associated with more favorable initial response than the other medications. © 2017 American Heart Association, Inc.

Induced abortion rates remained persistently high in the Volta Region of Ghana in the 5 years from 2006 to 2011. Some hospitals, both rural and urban, report induced abortion-related complications as one of the top ten conditions in hospital admissions. This study explored demographic and other factors associated with induced abortion, and also assessed awareness of abortion-related complications among women of reproductive age in the Volta Region. A quantitative, hospital-based, unmatched case-control study was performed. The Volta Region was stratified into two health administration zones, ie, north and south. For each zone, hospitals were stratified into government and private hospitals. Employing simple random sampling, one private and three government hospitals were selected from each zone. This study is therefore based on eight hospitals, ie, six government hospitals and two private hospitals. Marital status, employment status, number of total pregnancies, and knowledge about contraception were found to be associated with induced abortion. Multiple logistic regression showed a 4% reduction in the odds of induced abortion in married women compared with women who were single (odds ratio [OR] 0.11, 95% confidence interval [CI] 0.07-0.22). Unemployed women of reproductive age were found to be 0.35 times less likely to seek induced abortion compared with their employed counterparts (OR 0.35, CI 0.19-0.65). It was also observed that women with their second pregnancies were 3.8 times more likely to seek induced abortion and women with more than two pregnancies were 6.6 times more likely to do so (OR 3.81, CI 1.94-7.49 and OR 6.58, CI 2.58-16.79, respectively). Women with no knowledge of contraceptive methods were 4.6 times likely to seek induced abortion (OR 4.64, CI 1.39-15.4). Compared with women who had not had induced abortion, women with a high number of pregnancies and no contraceptive knowledge were more likely to have induced abortion. It was found that lack of knowledge about contraceptives and being single or employed were associated with increased likelihood of induced abortion. It was also found that women with a higher number of pregnancies have a greater odds of induced abortion. No association was found between induced abortion and maternal age, education, contraceptive use, or religion.

Background The incidence of opioid-related death in women has increased five-fold over the past decade. For many women, their initial opioid exposure will occur in the setting of routine medical care. Approximately 1 in 3 deliveries in the U.S. is by Cesarean and opioids are commonly prescribed for post-surgical pain management. Objective The objective of this study was to determine the risk that opioid naïve women prescribed opioids after Cesarean delivery will subsequently become consistent prescription opioid users in the year following delivery, and to identify predictors for this behavior. Study Design We identified women in a database of commercial insurance beneficiaries who underwent Cesarean delivery and who were opioid-naïve in the year prior to delivery. To identify persistent users of opioids, we used trajectory models, which group together patients with similar patterns of medication filling during follow-up, based on patterns of opioid dispensing in the year following Cesarean delivery. We then constructed a multivariable logistic regression model to identify independent risk factors for membership in the persistent user group. Results 285 of 80,127 (0.36%, 95% confidence interval 0.32 to 0.40), opioid-naïve women became persistent opioid users (identified using trajectory models based on monthly patterns of opioid dispensing) following Cesarean delivery. Demographics and baseline comorbidity predicted such use with moderate discrimination (c statistic = 0.73). Significant predictors included a history of cocaine abuse (risk 7.41%; adjusted odds ratio 6.11, 95% confidence interval 1.03 to 36.31) and other illicit substance abuse (2.36%; adjusted odds ratio 2.78, 95% confidence interval 1.12 to 6.91), tobacco use (1.45%; adjusted odds ratio 3.04, 95% confidence interval 2.03 to 4.55), back pain (0.69%; adjusted odds ratio 1.74, 95% confidence interval 1.33 to 2.29), migraines (0.91%; adjusted odds ratio 2.14, 95% confidence interval 1.58 to 2.90), antidepressant use (1.34%; adjusted odds ratio 3.19, 95% confidence interval 2.41 to 4.23) and benzodiazepine use (1.99%; adjusted odds ratio 3.72, 95% confidence interval 2.64 to 5.26) in the year prior to Cesarean delivery. Conclusions A very small proportion of opioid-naïve women (approximately 1 in 300) become persistent prescription opioid users following Cesarean delivery. Pre-existing psychiatric comorbidity, certain pain conditions, and substance use/abuse conditions identifiable at the time of initial opioid prescribing were predictors of persistent use.

Pre-B-cell colony-enhancing factor (PBEF) levels are elevated in bronchoalveolar lavage fluid and serum of patients with acute lung injury. There are several suspected functional polymorphisms of the corresponding PBEF gene. We hypothesized that variations in PBEF gene polymorphisms alter the risk of developing acute respiratory distress syndrome (ARDS). Nested case-control study. Tertiary academic medical center. We studied 375 patients with ARDS and 787 at-risk controls genotyped for the PBEF T-1001G and C-1543T polymorphisms. None. Patients with the -1001G (variant) allele had significantly greater odds of developing ARDS than wild-type homozygotes (odds ratio, 1.35; 95% confidence interval, 1.02-1.78). Patients with the -1543T (variant) allele did not have significantly different odds of developing ARDS than wild-type homozygotes (odds ratio, 0.86; 95% confidence interval, 0.65-1.13). When analysis was stratified by ARDS risk factor, -1543T was associated with decreased odds of developing ARDS in septic shock patients (odds ratio, 0.66; 95% confidence interval, 0.45-0.97). Also, -1001G was associated with increased hazard of intensive care unit mortality, whereas -1543T was associated with decreased hazard of 28-day and 60-day ARDS mortality, as well as shorter duration of mechanical ventilation. Similar results were found in analyses of the related GC (-1001G:-1543C) and TT (-1001T:-1543T) haplotypes. The PBEFT-1001G variant allele and related haplotype are associated with increased odds of developing ARDS and increased hazard of intensive care unit mortality among at-risk patients, whereas the C-1543T variant allele and related haplotype are associated with decreased odds of ARDS among patients with septic shock and better outcomes among patients with ARDS.

Current knowledge regarding psychiatric disorders and crime in youth is limited to juvenile justice and community samples. This study examined relationships between psychiatric disorders and self-reported crime involvement in a sample of youth representative of the US population. The National Comorbidity Survey-Adolescent Supplement (N = 10,123; ages 13-17 years; 2001-2004) was used to examine the relationship between lifetime DSM-IV-based diagnoses, reported crime (property, violent, other), and arrest history. Logistic regression compared the odds of reported crime involvement with specific psychiatric disorders to those without any diagnoses, and examined the odds of crime by psychiatric comorbidity. Prevalence of crime was 18.4%. Youth with lifetime psychiatric disorders, compared to no disorders, had significantly greater odds of crime, including violent crime. For violent crime resulting in arrest, conduct disorder (CD) (odds ratio OR = 57.5; 95% CI = 30.4, 108.8), alcohol use disorders (OR = 19.5; 95% CI = 8.8, 43.2), and drug use disorders (OR = 16.1; 95% CI = 9.3, 27.7) had the greatest odds with similar findings for violent crime with no arrest. Psychiatric comorbidity increased the odds of crime. Youth with 3 or more diagnoses (16.0% of population) accounted for 54.1% of those reporting arrest for violent crime. Youth with at least 1 diagnosis committed 85.8% of crime, which was reduced to 67.9% by removing individuals with CD. Importantly, 88.2% of youth with mental illness reported never having committed any crime. Our findings highlight the importance of improving access to mental health services for youthful offenders in community settings, given the substantial associations found between mental illness and crime in this nationally representative epidemiological sample.

To our knowledge, little research has examined concussion across the youth/adolescent spectrum and even less has examined concussion-related outcomes (ie, symptoms and return to play). To examine and compare sport-related concussion outcomes (symptoms and return to play) in youth, high school, and collegiate football athletes. Athletic trainers attended each practice and game during the 2012 to 2014 seasons and reported injuries. For this descriptive, epidemiological study, data were collected from youth, high school, and collegiate football teams, and the analysis of the data was conducted between July 2015 and September 2015. The Youth Football Surveillance System included more than 3000 youth football athletes aged 5 to 14 years from 118 teams, providing 310 team seasons (ie, 1 team providing 1 season of data). The National Athletic Treatment, Injury, and Outcomes Network Program included 96 secondary school football programs, providing 184 team seasons. The National Collegiate Athletic Association Injury Surveillance Program included 34 college football programs, providing 71 team seasons. We calculated the mean number of symptoms, prevalence of each symptom, and the proportion of patients with concussions that had long return-to-play time (ie, required participation restriction of at least 30 days). Generalized linear models were used to assess differences among competition levels in the mean number of reported symptoms. Logistic regression models estimated the odds of return to play at less than 24 hours and at least 30 days. Overall, 1429 sports-related concussions were reported among youth, high school, and college-level football athletes with a mean (SD) of 5.48 (3.06) symptoms. Across all levels, 15.3% resulted return to play at least 30 days after the concussion and 3.1% resulted in return to play less than 24 hours after the concussion. Compared with youth, a higher number of concussion symptoms were reported in high school athletes (β = 1.39; 95% CI, 0.55-2.24). Compared with college athletes, the odds of return to play at least 30 days after injury were larger in youth athletes (odds ratio, 2.75; 95% CI, 1.10- 6.85) and high school athletes (odds ratio, 2.89; 95% CI, 1.61-5.19). The odds of return to play less than 24 hours after injury were larger in youth athletes than high school athletes (odds ratio, 6.23; 95% CI, 1.02-37.98). Differences in concussion-related outcomes existed by level of competition and may be attributable to genetic, biologic, and/or developmental differences or level-specific variations in concussion-related policies and protocols, athlete training management, and athlete disclosure. Given the many organizational, social environmental, and policy-related differences at each level of competition that were not measured in this study, further study is warranted to validate our findings.

Aim To assess socioeconomic inequality regarding specific preventive interventions (fissure sealants or any treatment to prevent caries) and dental visits among UK children.Method Data were from the Children's Dental Health Survey 2003, which included participants from England, Wales, Scotland, and Northern Ireland. The number of children in the analysis was 2,286. Variables were sex, age, area of residency (for example, England), mother's education, family social class, and deprivation level. Descriptive and regression analyses were performed.Results There were no significant socioeconomic differences in the use of preventive services. Deprivation and family social class (for example, intermediate and manual) were significantly associated with less regular dental visits (odd ratio 0.41, 95% CI [0.28, 0.63]; odd ratio 0.53, 95% CI [0.31, 0.89]; odd ratio 0.37, 95% CI [0.24, 0.58], respectively). Regular dental visits were associated with reporting preventive care for caries (odds ratio 2.25, 95% CI [1.45, 3.49]) and with the number of sealed tooth surfaces (rate ratio 1.73, 95% CI [1.16, 2.60]).Conclusion Despite apparent socioeconomic inequalities in regular dental visits, there was no significant inequality in using specific preventive interventions by children in the UK. This finding should be interpreted with caution considering the relatively small subsample included in this analysis.

This systematic review and meta-analysis evaluated the associations between shift work patterns and risks of specific types of obesity. PubMed was searched until March 2017 for observational studies that examined the relationships between shift work patterns and obesity. Odds ratio for obesity was extracted using a fixed-effects or random-effects model. Subgroup meta-analyses were carried out for study design, specific obesity types and characteristics of shift work pattern. A total of 28 studies were included in this meta-analysis. The overall odds ratio of night shift work was 1.23 (95% confidence interval = 1.17-1.29) for risk of obesity/overweight. Cross-sectional studies showed a higher risk of 1.26 than those with the cohort design (risk ratio = 1.10). Shift workers had a higher frequency of developing abdominal obesity (odds ratio = 1.35) than other obesity types. Permanent night workers demonstrated a 29% higher risk than rotating shift workers (odds ratio 1.43 vs. 1.14). This meta-analysis confirmed the risks of night shift work for the development of overweight and obesity with a potential gradient association suggested, especially for abdominal obesity. Modification of working schedules is recommended, particularly for prolonged permanent night work. More accurate and detailed measurements on shift work patterns should be conducted in future research. © 2017 World Obesity Federation.

This study used Monte Carlo simulation to examine the properties of the overall odds ratio (OOR), which was recently introduced as an index for overall effect size in multiple logistic regression. It was found that the OOR was relatively independent of study base rate and performed better than most commonly used R-square analogs in indexing model…

Acute kidney injury frequently complicates critical illness and is associated with high morbidity and mortality. Frailty is common in critical illness survivors, but little is known about the impact of acute kidney injury. We examined the association of acute kidney injury and frailty within a year of hospital discharge in survivors of critical illness. Secondary analysis of a prospective cohort study. Medical/surgical ICU of a U.S. tertiary care medical center. Three hundred seventeen participants with respiratory failure and/or shock. None. Acute kidney injury was determined using Kidney Disease Improving Global Outcomes stages. Clinical frailty status was determined using the Clinical Frailty Scale at 3 and 12 months following discharge. Covariates included mean ICU Sequential Organ Failure Assessment score and Acute Physiology and Chronic Health Evaluation II score as well as baseline comorbidity (i.e., Charlson Comorbidity Index), kidney function, and Clinical Frailty Scale score. Of 317 patients, 243 (77%) had acute kidney injury and one in four patients with acute kidney injury was frail at baseline. In adjusted models, acute kidney injury stages 1, 2, and 3 were associated with higher frailty scores at 3 months (odds ratio, 1.92; 95% CI, 1.14-3.24; odds ratio, 2.40; 95% CI, 1.31-4.42; and odds ratio, 4.41; 95% CI, 2.20-8.82, respectively). At 12 months, a similar association of acute kidney injury stages 1, 2, and 3 and higher Clinical Frailty Scale score was noted (odds ratio, 1.87; 95% CI, 1.11-3.14; odds ratio, 1.81; 95% CI, 0.94-3.48; and odds ratio, 2.76; 95% CI, 1.34-5.66, respectively). In supplemental and sensitivity analyses, analogous patterns of association were observed. Acute kidney injury in survivors of critical illness predicted worse frailty status 3 and 12 months postdischarge. These findings have important implications on clinical decision making among acute kidney injury survivors and underscore the need to understand the drivers of frailty to improve patient-centered outcomes.

Site fidelity, territory fidelity, and natal philopatry in Willow Flycatchers (Empidonax traillii)

I investigated the causes and consequences of adult breeding-site fidelity, territory fidelity, and natal philopatry in Willow Flycatchers (Empidonax traillii) in southeastern Oregon over a 10-year period, testing the general hypothesis that fidelity and dispersal distances are influenced by previous breeding performance. Willow Flycatchers adhered to the generally observed tendencies of passerine birds for low natal philopatry and high breedingsite fidelity. Site fidelity (return to the study area) of adult males (52.0%) and females (51.3%), and median dispersal distances between seasons (16 m vs. 19 m) were similar. Previous breeding performance and residency (age-experience), but not study-site quality, explained site fidelity in females. Site fidelity of females rearing 4–5 young (64.4%) exceeded that of unsuccessful females (40.0%), breeding dispersal was less (successful: 15 m; unsuccessful: 33 m), and novice residents were more site-faithful than former residents. Probability of site fidelity was higher for previously successful females (odds ratio = 4.76), those with greater seasonal fecundity (odds ratio = 1.58), novice residents (odds ratio = 1.41), and unparasitized females (odds ratio = 2.76). Male site fidelity was not related to residency, site quality, or previous breeding performance. Territory fidelity (return to the previous territory) in females was best explained by previous breeding performance, but not by site quality or residency. Previously successful females were more likely to return to their territory of the previous season than either unsuccessful (odds ratio = 14.35) or parasitized birds (odds ratio = 6.38). Male territory fidelity was not related to residency, site quality, or previous breeding performance. Natal philopatry was low (7.8%) and similar for males and females. Site quality appeared to influence philopatry, given that no birds reared at a low-quality study site returned there to breed, and birds reared there dispersed farther than birds reared at two other study sites. My results partially support the hypothesis that site fidelity is an adaptive response: (1) previously successful females that switched territories underperformed those that did not switch (P = 0.01); and (2) previously unsuccessful females that switched territories outperformed those that did not switch, but not significantly (P = 0.22).

In Crohn disease, bowel-preserving surgery is necessary to prevent short bowel syndrome due to repeated operations. This study aimed to determine the remnant small bowel length cut-off and to evaluate the clinical factors related to nutritional status after small bowel resection in Crohn disease.We included 394 patients (69.3% male) who underwent small bowel resection for Crohn disease between 1991 and 2012. Patients who were classified as underweight (body mass index < 17.5) or at high risk of nutrition-related problems (modified nutritional risk index < 83.5) were regarded as having a poor nutritional status. Preliminary remnant small bowel length cut-offs were determined using receiver operating characteristic curves. Variables associated with poor nutritional status were assessed retrospectively using Student t tests, chi-squared tests, Fisher exact tests, and logistic regression analyses.The mean follow-up period was 52.9 months and the mean patient ages at the time of the last bowel surgery and last follow-up were 31.2 and 35.7 years, respectively. The mean remnant small bowel length was 331.8 cm. Forty-three patients (10.9%) underwent ileostomy, 309 (78.4%) underwent combined small bowel and colon resection, 111 (28.2%) had currently active disease, and 105 (26.6%) underwent at least 2 operations for recurrent disease. The mean body mass index and modified nutritional risk index were 20.6 and 100.8, respectively. The independent factors affecting underweight status were remnant small bowel length ≤240 cm (odds ratio: 4.84, P < 0.001), ileostomy (odds ratio: 4.70, P < 0.001), and currently active disease (odds ratio: 4.16, P < 0.001). The independent factors affecting high nutritional risk were remnant small bowel length ≤230 cm (odds ratio: 2.84, P = 0.012), presence of ileostomy (odds ratio: 3.36, P = 0.025), and currently active disease (odds ratio: 4.90, P < 0.001).Currently active disease, ileostomy, and remnant small bowel length ≤230 cm are risk factors affecting the poor nutritional status of patients with Crohn disease after small bowel resection.

Embolic events are a major cause of morbidity and mortality in patients with infective endocarditis. We analyzed the database of the prospective cohort study SEI in order to identify factors associated with the occurrence of embolic events and to develop a scoring system for the assessment of the risk of embolism. We retrospectively analyzed 1456 episodes of infective endocarditis from the multicenter study SEI. Predictors of embolism were identified. Risk factors identified at multivariate analysis as predictive of embolism in left-sided endocarditis, were used for the development of a risk score: 1 point was assigned to each risk factor (total risk score range: minimum 0 points; maximum 2 points). Three categories were defined by the score: low (0 points), intermediate (1 point), or high risk (2 points); the probability of embolic events per risk category was calculated for each day on treatment (day 0 through day 30). There were 499 episodes of infective endocarditis (34%) that were complicated by ≥ 1 embolic event. Most embolic events occurred early in the clinical course (first week of therapy: 15.5 episodes per 1000 patient days; second week: 3.7 episodes per 1000 patient days). In the total cohort, the factors associated with the occurrence of embolism at multivariate analysis were prosthetic valve localization (odds ratio, 1.84), right-sided endocarditis (odds ratio, 3.93), Staphylococcus aureus etiology (odds ratio, 2.23) and vegetation size ≥ 13 mm (odds ratio, 1.86). In left-sided endocarditis, Staphylococcus aureus etiology (odds ratio, 2.1) and vegetation size ≥ 13 mm (odds ratio, 2.1) were independently associated with embolic events; the 30-day cumulative incidence of embolism varied with risk score category (low risk, 12%; intermediate risk, 25%; high risk, 38%; p < 0.001). Staphylococcus aureus etiology and vegetation size are associated with an increased risk of embolism. In left-sided endocarditis, a simple scoring system, which combines etiology and vegetation size with time on antimicrobials, might contribute to a better assessment of the risk of embolism, and to a more individualized analysis of indications and contraindications for early surgery.

In the ATLANTIC (Administration of Ticagrelor in the catheterization laboratory or in the Ambulance for New ST elevation myocardial Infarction to open the Coronary artery) trial the early use of aspirin, anticoagulation, and ticagrelor coupled with very short medical contact-to-balloon times represent good indicators of optimal treatment of ST-elevation myocardial infarction and an ideal setting to explore which factors may influence coronary reperfusion beyond a well-established pre-hospital system. This study sought to evaluate predictors of complete ST-segment resolution after percutaneous coronary intervention in ST-elevation myocardial infarction patients enrolled in the ATLANTIC trial. ST-segment analysis was performed on electrocardiograms recorded at the time of inclusion (pre-hospital electrocardiogram), and one hour after percutaneous coronary intervention (post-percutaneous coronary intervention electrocardiogram) by an independent core laboratory. Complete ST-segment resolution was defined as ≥70% ST-segment resolution. Complete ST-segment resolution occurred post-percutaneous coronary intervention in 54.9% ( n=800/1456) of patients and predicted lower 30-day composite major adverse cardiovascular and cerebrovascular events (odds ratio 0.35, 95% confidence interval 0.19-0.65; p<0.01), definite stent thrombosis (odds ratio 0.18, 95% confidence interval 0.02-0.88; p=0.03), and total mortality (odds ratio 0.43, 95% confidence interval 0.19-0.97; p=0.04). In multivariate analysis, independent negative predictors of complete ST-segment resolution were the time from symptoms to pre-hospital electrocardiogram (odds ratio 0.91, 95% confidence interval 0.85-0.98; p<0.01) and diabetes mellitus (odds ratio 0.6, 95% confidence interval 0.44-0.83; p<0.01); pre-hospital ticagrelor treatment showed a favorable trend for complete ST-segment resolution (odds ratio 1.22, 95% confidence interval 0.99-1.51; p=0.06). This study confirmed that post-percutaneous coronary intervention complete ST-segment resolution is a valid surrogate marker for cardiovascular clinical outcomes. In the current era of ST-elevation myocardial infarction reperfusion, patients' delay and diabetes mellitus are independent predictors of poor reperfusion and need specific attention in the future.

Background and objectives Despitethe multiple depicted associations of CKD with reduced cardiovascular and overall prognoses, the association of CKD with outcome of patients undergoing transcatheter aortic valve implantation has still not been well described. Design, setting, participants, & measurements Data from all hospitalized patients who underwent transcatheter aortic valve implantation procedures between January 1, 2010 and December 31, 2013 in Germany were evaluated regarding influence of CKD, even in the earlier stages, on morbidity, in-hospital outcomes, and costs. Results A total of 28,716 patients were treated with transcatheter aortic valve implantation. A total of 11,189 (39.0%) suffered from CKD. Patients with CKD were predominantly women; had higher rates of comorbidities, such as coronary artery disease, heart failure at New York Heart Association 3/4, peripheral artery disease, and diabetes; and had a 1.3-fold higher estimated logistic European System for Cardiac Operative Risk Evaluation value. In-hospital mortality was independently associated with CKD stage ≥3 (up to odds ratio, 1.71; 95% confidence interval, 1.35 to 2.17; P<0.05), bleeding was independently associated with CKD stage ≥4 (up to odds ratio, 1.82; 95% confidence interval, 1.47 to 2.24; P<0.001), and AKI was independently associated with CKD stages 3 (odds ratio, 1.83; 95% confidence interval, 1.62 to 2.06) and 4 (odds ratio, 2.33; 95% confidence interval, 1.92 to 2.83 both P<0.001). The stroke risk, in contrast, was lower for patients with CKD stages 4 (odds ratio, 0.23; 95% confidence interval, 0.16 to 0.33) and 5 (odds ratio, 0.24; 95% confidence interval, 0.15 to 0.39; both P<0.001). Lengths of hospital stay were, on average, 1.2-fold longer, whereas reimbursements were, on average, only 1.03-fold higher in patients who suffered from CKD. Conclusions This analysis illustrates for the first time on a nationwide basis the association of CKD with adverse outcomes in patients who underwent transcatheter aortic valve implantation. Thus, classification of CKD stages before transcatheter aortic valve implantation is important for appropriate risk stratification. PMID:28289067

Our objective was to compare the effectiveness of metformin plus clomiphene citrate vs. gonadotrophins, laparoscopic ovarian diathermy, aromatase inhibitors, N-acetyl-cysteine and other insulin sensitizers+clomiphene for improving fertility outcomes in women with clomiphene-resistant polycystic ovary syndrome. PubMed, SCOPUS and CENTRAL databases were searched until April 2014 with the key words: PCOS, polycystic ovary syndrome, metformin, clomiphene citrate, ovulation induction and pregnancy. The search was limited to articles conducted with humans and published in English. The PRISMA statement was followed. Twelve randomized controlled trials (n = 1411 women) were included. Ovulation and clinical pregnancy rates per woman randomized. Compared with gonadotrophins, the metformin+clomiphene combination resulted in significantly fewer ovulations (odds ratio 0.25; 95% confidence interval 0.15-0.41; p < 0.00001, 3 trials, I(2) = 85%, n = 323) and pregnancies (odds ratio 0.45; 95% confidence interval 0.27-0.75; p = 0.002, 3 trials, I(2) = 0%, n = 323). No significant differences were found when metformin+clomiphene was compared with laparoscopic ovarian diathermy (odds ratio 0.88; 95% confidence interval 0.53-1.47; p = 0.62, 1 trial, n = 282; odds ratio 0.96; 95% confidence interval 0.60-1.54; p = 0.88, 2 trials, I(2) = 0%, n = 332, for ovulation and pregnancy rates, respectively). Likewise, no differences were observed in comparison with aromatase inhibitors (odds ratio 0.88; 95% confidence interval 0.58-1.34; p = 0.55, 3 trials, I(2) = 3%, n = 409; odds ratio 0.85; 95% confidence interval 0.53-1.36; p = 0.50, 2 trials, n = 309, for ovulation and pregnancy rates, respectively). There is evidence for the superiority of gonadotrophins, but the metformin+clomiphene combination is mainly relevant for clomiphene-resistant polycystic ovary syndrome patients and, if not effective, a next step could be gonadotrophins. More attempts with metformin+clomiphene are only relevant if there is limited access to gonadotrophins. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

To report prevalence, risk factors and clinical outcomes for presumptive gastric dilation-volvulus diagnosed among an emergency-care population of UK dogs. The study used a cross-sectional design using emergency-care veterinary clinical records from the VetCompass Programme spanning September 1, 2012 to February 28, 2014 and risk factor analysis using multivariable logistic regression modelling. The study population comprised 77,088 dogs attending 50 Vets Now clinics. Overall, 492 dogs had presumptive gastric dilation-volvulus diagnoses, giving a prevalence of 0·64% (95% Confidence interval: 0·58 to 0·70%). Compared with cross-bred dogs, breeds with the highest odds ratios for the diagnosis of presumptive gastric dilation-volvulus were the great Dane (odds ratio: 114·3, 95% Confidence interval 55·1 to 237·1, P<0·001), akita (odds ratio: 84·4, 95% Confidence interval 33·6 to 211·9, P<0·001) and dogue de Bordeaux (odds ratio: 82·9, 95% Confidence interval 39·0 to 176·3, P<0·001). Odds increased as dogs aged up to 12 years and neutered male dogs had 1·3 (95% Confidence interval 1·0 to 1·8, P=0·041) times the odds compared with entire females. Of the cases that were presented alive, 49·7% survived to discharge overall, but 79·3% of surgical cases survived to discharge. Approximately 80% of surgically managed cases survived to discharge.

The fraternal birth order effect is the tendency for older brothers to increase the odds of homosexuality in later-born males. This study compared the strength of the effect in subjects from small versus large families and in homosexual subjects with masculine versus feminine gender identities. Meta-analyses were conducted on 30 homosexual and 30 heterosexual groups from 26 studies, totaling 7140 homosexual and 12,837 heterosexual males. The magnitude of the fraternal birth order effect was measured with a novel variable, the Older Brothers Odds Ratio, computed as (homosexuals' older brothers ÷ homosexuals' other siblings) ÷ (heterosexuals' older brothers ÷ heterosexuals' other siblings), where other siblings = older sisters + younger brothers + younger sisters. An Older Brothers Odds Ratio of 1.00 represents no effect of sexual orientation; values over 1.00 are positive evidence for the fraternal birth order effect. Evidence for the reliability of the effect was consistent. The Older Brothers Odds Ratio was significantly >1.00 in 20 instances, >1.00 although not significantly in nine instances, and nonsignificantly <1.00 in 1 instance. The pooled Older Brothers Odds Ratio for all samples was 1.47, p < .00001. Subgroups analyses showed that the magnitude of the effect was significantly greater in the 12 feminine or transgender homosexual groups than in the other 18 homosexual groups. There was no evidence that the magnitude of the effect differs according to family size.

Evaluate effect of gender role attitudes on tobacco and alcohol use among Argentinean girls. Cross-sectional survey of 10th grade students attending 27 randomly selected schools in Jujuy, Argentina. Questions about tobacco and alcohol use were adapted from global youth surveys. Five items with 5-point response options of agreement-disagreement assessed attitude towards egalitarian (higher score) gender roles. 2133 girls, aged 13-18 years, 71% Indigenous, 22% mixed Indigenous/European, and 7% European responded. Of these, 60% had ever smoked, 32% were current smokers, 58% ever drinkers, 27% drank in previous month, and 13% had ≥5 drinks on one occasion. Mean response to the gender role scale was 3.49 (95% Confidence Intervals = 3.41-3.57) out of 5 tending toward egalitarian attitudes. Logistic regression models using the gender role scale score as the main predictor and adjusting for demographic and social confounders showed that egalitarian gender role was associated with ever smoking (Odds Ratio = 1.25; 95% Confidence Intervals 1.09-1.44), ever drinking (Odds Ratio = 1.24; 95% Confidence Intervals 1.10-1.40), drinking in prior month (Odds Ratio = 1.21; 95% Confidence Intervals 1.07-1.37) and ≥5 drinks on one occasion (Odds Ratio = 1.15; 95% Confidence Intervals 1.00-1.33), but was not significant for current smoking. Girls in Jujuy who reported more egalitarian gender role attitudes had higher odds of smoking or drinking. Copyright © 2013 Elsevier Inc. All rights reserved.

Physical exertion, anger, and emotional upset are reported to trigger acute myocardial infarction (AMI). In the INTERHEART study, we explored the triggering association of acute physical activity and anger or emotional upset with AMI to quantify the importance of these potential triggers in a large, international population. INTERHEART was a case-control study of first AMI in 52 countries. In this analysis, we included only cases of AMI and used a case-crossover approach to estimate odds ratios for AMI occurring within 1 hour of triggers. Of 12 461 cases of AMI 13.6% (n=1650) engaged in physical activity and 14.4% (n=1752) were angry or emotionally upset in the case period (1 hour before symptom onset). Physical activity in the case period was associated with increased odds of AMI (odds ratio, 2.31; 99% confidence interval [CI], 1.96-2.72) with a population-attributable risk of 7.7% (99% CI, 6.3-8.8). Anger or emotional upset in the case period was associated with an increased odds of AMI (odds ratio, 2.44; 99% CI, 2.06-2.89) with a population-attributable risk of 8.5% (99% CI, 7.0-9.6). There was no effect modification by geographical region, prior cardiovascular disease, cardiovascular risk factor burden, cardiovascular prevention medications, or time of day or day of onset of AMI. Both physical activity and anger or emotional upset in the case period were associated with a further increase in the odds of AMI (odds ratio, 3.05; 99% CI, 2.29-4.07; P for interaction <0.001).

We perform an analysis of the number of sunspot groups in activity cycles from 1610 through the present. Here we use the G{sub n} index, which is defined as the average daily number of sunspot groups in cycle n. There is a high positive correlation between the parameter G{sub n} in the current cycle and an analogous parameter in the following cycle G{sub n{sub +1}} both for pairs of even-odd cycles and odd-even activity cycles. In cycle Nos. 10-21 for pairs of even-odd cycles, the ratio of parameter G{sub n} corresponds to the GO rule G{sub n{sub +1}{sup odd}}/G{sub n}{supmore » even}>1. However, during the period {approx}1745-1850, odd cycles were less than the preceding even cycles G{sub n{sub +1}{sup odd}}/G{sub n}{sup even}<1. The ratio of the parameter G{sub n{sub +1}{sup odd}}/G{sub n}{sup even} has a long-term variation within the range 0.5-1.5 with a period of about 21 activity cycles, and it proves the reversal of the GO rule.« less

To evaluate the association of iodine nutrition status and knowledge, attitude, and behavior in Tehranian women after 2 decades without updating public education. Cross-sectional study. Eight health care centers from 4 district areas of Tehran. A total of 383 women aged ≥ 19 years, randomly selected. Iodine concentration of 24-hour urine samples, iodine content of household salts, and knowledge, attitude, and practice scores regarding iodine nutrition and iodized salt. Multiple logistic regression was used to identify the association of knowledge, attitude, and practice scores with urinary iodine concentration (UIC) < 100 μg/L. The percentages of Tehranian women with high knowledge, attitude, and practice scores were 26%, 26%, and 14%, respectively. Practice score was significantly different between females with UIC < 100 and > 100 μg/L (P = .001). Risk of UIC < 100 μg/L in women of childbearing age (19-45 years) after adjustment of education level, region of residence, and iodine content of salt was significantly associated with intermediate practice score (odds ratio = 2.6; 95% confidence interval, 1.3-13.2). Marginally suboptimal iodine status in women of childbearing age can be attributed to inappropriate practices, but not to knowledge and attitude.

A wave of bombings struck France in 1995 and 1996, killing 12 people and injuring more than 200. The authors conducted follow-up evaluations with the victims in 1998 to determine the prevalence of and factors associated with posttraumatic stress disorder (PTSD). Victims directly exposed to the bombings (N=228) were recruited into a retrospective, cross-sectional study. Computer-assisted telephone interviews were conducted to evaluate PTSD, per DSM-IV criteria, and to assess health status before the attack, initial injury severity and perceived threat at the time of attack, and psychological symptoms, cosmetic impairment, hearing problems, and health service use at the time of the follow-up evaluation. Factors associated with PTSD were investigated with univariate logistic regression followed by multiple logistic regression analyses. A total of 196 respondents (86%) participated in the study. Of these, 19% had severe initial physical injuries (hospitalization exceeding 1 week). Problems reported at the follow-up evaluation included attack-related hearing problems (51%), cosmetic impairment (33%), and PTSD (31%) (95% confidence interval=24.5%-37.5%). Results of logistic regression analyses indicated that the risk of PTSD was significantly higher among women (odds ratio=2.54), participants age 35-54 (odds ratio=2.83), and those who had severe initial injuries (odds ratio=2.79) or cosmetic impairment (odds ratio=2.74) or who perceived substantial threat during the attack (odds ratio=3.99). The high prevalence of PTSD 2.6 years on average after a terrorist attack emphasizes the need for improved health services to address the intermediate and long-term consequences of terrorism.

Background We reviewed studies that analyzed cysticercosis (CC), neurocysticercosis (NCC) and epilepsy across Latin America, Asia and Sub-Saharan Africa, to estimate the odds ratio and etiologic fraction of epilepsy due to CC in tropical regions. Methodology We conducted a systematic review of the literature on cysticercosis and epilepsy in the tropics, collecting data from case-control and cross-sectional studies. Exposure criteria for CC included one or more of the following: serum ELISA or EITB positivity, presence of subcutaneous cysts (both not verified and unverified by histology), histology consistent with calcified cysts, and brain CT scan consistent with NCC. A common odds-ratio was then estimated using meta-analysis. Principal findings 37 studies from 23 countries were included (n = 24,646 subjects, 14,934 with epilepsy and 9,712 without epilepsy). Of these, 29 were case-control (14 matched). The association between CC and epilepsy was significant in 19 scientific articles. Odds ratios ranged from 0.2 to 25.4 (a posteriori power 4.5–100%) and the common odds ratio was 2.7 (95% CI 2.1–3.6, p <0.001). Three subgroup analyses performed gave odds ratios as: 2.2 (EITB-based studies), 3.2 (CT-based studies), 1.9 (neurologist-confirmed epilepsy; door-to-door survey and at least one matched control per case). Etiologic fraction was estimated to be 63% in the exposed group among the population. Significance Despite differences in findings, this meta-analysis suggests that cysticercosis is a significant contributor to late-onset epilepsy in tropical regions around the world, and its impact may vary depending on transmission intensity.

Vaginal delivery is recommended after intrauterine fetal death. However, little is known about the risk of shoulder dystocia in these deliveries. We studied whether intrauterine fetal death increases the risk of shoulder dystocia at delivery. In this population-based register study using the Medical Birth Registry of Norway, we included all singleton pregnancies with vaginal delivery of offspring in cephalic presentation in Norway during the period 1967-2012 (n = 2 266 118). Risk of shoulder dystocia was estimated as absolute risk (%) and odds ratio with 95% confidence interval. Adjustment was made for offspring birthweight (in grams). We performed sub-analyses within categories of birthweight (<4000 and ≥4000 g) and in pregnancies with maternal diabetes. Shoulder dystocia occurred in 1.1% of pregnancies with intrauterine fetal death and in 0.8% of pregnancies without intrauterine fetal death (p < 0.0001) (crude odds ratio 1.5, 95% confidence interval 1.2-4.9). After adjustment for birthweight, the odds ratio was 5.9 (95% confidence interval 4.7-7.4). In pregnancies with birthweight ≥4000 g, shoulder dystocia occurred in 14.6% of pregnancies with intrauterine fetal death and in 2.8% of pregnancies without intrauterine fetal death (p < 0.001) (crude odds ratio 5.9, 95% confidence interval 4.5-7.9). In pregnancies with birthweight ≥4000 g and concurrent maternal diabetes, shoulder dystocia occurred in 57.1% of pregnancies with intrauterine fetal death and 9.6% of pregnancies without intrauterine fetal death (p < 0.001) (crude odds ratio 12.6, 95% confidence interval 5.9-26.9). Intrauterine fetal death increased the risk of shoulder dystocia at delivery, and the absolute risk of shoulder dystocia was particularly high if offspring birthweight was high and the mother had diabetes. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

In 1999, in France, before considering modifications in drug legislation, the government requested a study of the effect of illicit drugs on the risk of road crashes. It implemented a systematic screening of illicit drugs for all drivers involved in fatal crashes between October 2001 and September 2003. Within the European DRUID project, the study was restricted to car drivers. The project reported here is a responsibility analysis and, as such, it belongs to the framework of case-control studies; the outcome of interest is “being responsible for a fatal crash”. It was assessed with a method adapted from Robertson and Drummer. Cases are the 4,946 car drivers who are responsible for the crash; controls are the 1,986 car drivers selected from the non-responsible car drivers, in a way that makes the control group similar to the general driving population. The effect of cannabis on fatal crash responsibility is significant after adjustment for age, sex and alcohol: adjusted odds ratio is 1.89 [1.43–2.51]. The dose-response effect is significant (p=0.0001). For alcohol (≥0.1 g/l), the adjusted odds ratio for responsibility is 8.39 [6.95–10.11]. No interaction was found between alcohol and cannabis. For amphetamine, cocaine and opiates, adjusted odds ratios were not significantly different from 1. However the statistical power is low. The study finds similar odds ratios for alcohol as previously published. For cannabis, the significant odds ratio together with the significant dose-response effect indicates a causal relationship between cannabis and road crashes. A multiplicative effect between cannabis and alcohol was noted. PMID:22105404

Following childbirth, a vast number of women experience some degree of mood swings, while some experience symptoms of postpartum posttraumatic stress disorder. Using a biopsychosocial model, the primary aim of this study was to identify predictors of posttraumatic stress disorder and its symptomatology following childbirth. This observational, longitudinal study included 372 postpartum women. In order to explore biopsychosocial predictors, participants completed several questionnaires 3-5 days after childbirth: the Impact of Events Scale Revised, the Big Five Inventory, The Edinburgh Postnatal Depression Scale, breastfeeding practice and social and demographic factors. Six to nine weeks after childbirth, participants re-completed the questionnaires regarding psychiatric symptomatology and breastfeeding practice. Using a multivariate level of analysis, the predictors that increased the likelihood of postpartum posttraumatic stress disorder symptomatology at the first study phase were: emergency caesarean section (odds ratio 2.48; confidence interval 1.13-5.43) and neuroticism personality trait (odds ratio 1.12; confidence interval 1.05-1.20). The predictor that increased the likelihood of posttraumatic stress disorder symptomatology at the second study phase was the baseline Impact of Events Scale Revised score (odds ratio 12.55; confidence interval 4.06-38.81). Predictors that decreased the likelihood of symptomatology at the second study phase were life in a nuclear family (odds ratio 0.27; confidence interval 0.09-0.77) and life in a city (odds ratio 0.29; confidence interval 0.09-0.94). Biopsychosocial theory is applicable to postpartum psychiatric disorders. In addition to screening for depression amongst postpartum women, there is a need to include other postpartum psychiatric symptomatology screenings in routine practice.

To explore factors associated with neurological recovery at 1 year relative to hospital discharge after cardiac arrest. Observational, retrospective review of a prospectively collected cohort. Medical or surgical ICUs in a single tertiary care center. Older than 18 years, resuscitated following either in-hospital or out-of-hospital cardiac arrest and considered for targeted temperature management between 2007 and 2013. None. Logistic regressions to determine factors associated with a poor recovery pattern after 1 year, defined as persistent Cerebral Performance Category Score 3-4 or any worsening of Cerebral Performance Category Score relative to discharge status. In total, 30% (117/385) of patients survived to hospital discharge; among those discharged with Cerebral Performance Category Score 1, 2, 3, and 4, good recovery pattern was seen in 54.5%, 48.4%, 39.5%, and 0%, respectively. Significant variables showing trends in associations with a poor recovery pattern (62.5%) in a multivariate model were age more than 70 years (odds ratio, 4; 95% CIs, 1.1-15; p = 0.04), Hispanic ethnicity (odds ratio, 4; CI, 1.2-13; p = 0.02), and discharge disposition (home needing out-patient services (odds ratio, 1), home requiring no additional services (odds ratio, 0.15; CI, 0.03-0.8; p = 0.02), acute rehabilitation (odds ratio, 0.23; CI, 0.06-0.9; p = 0.04). Patients discharged with mild or moderate cerebral dysfunction sustained their risk of neurological worsening within 1 year of cardiac arrest. Old age, Hispanic ethnicity, and discharge disposition of home with out-patient services may be associated with a poor 1 year neurological recovery pattern after hospital discharge from cardiac arrest.

Previous surveys of gastrointestinal symptoms after spinal cord injury have not used validated questionnaires and have not focused on the full spectrum of such symptoms and their relationship to factors, such as level of spinal cord injury and psychologic dysfunction. This study was designed to detail the spectrum and prevalence of gastrointestinal symptoms in spinal cord injury and to determine clinical and psychologic factors associated with such symptoms. Established spinal cord injury patients (>12 months) randomly selected from a spinal cord injury database completed the following three questionnaires: 1) Rome II Integrative Questionnaire, 2) Hospital Anxiety and Depression Scale, and 3) Burwood Bowel Dysfunction after spinal cord injury. A total of 110 patients participated. The prevalence of abdominal bloating and constipation were 22 and 46 percent, respectively. Bloating was associated with cervical (odds ratio = 9.5) and lumbar (odds ratio = 12.1) level but not with thoracic level of injury. Constipation was associated with a higher level of injury (cervical odds ratio = 5.6 vs. lumbar) but not with psychologic factors. In contrast, abdominal pain (33 percent) and fecal incontinence (41 percent) were associated with higher levels of anxiety (odds ratio = 6.8, and odds ratio = 2.4) but not with the level of injury. There is a high prevalence and wide spectrum of gastrointestinal symptoms in spinal cord injury. Abdominal bloating and constipation are primarily related to specific spinal cord levels of injury, whereas abdominal pain and fecal incontinence are primarily associated with higher levels of anxiety. Based on our findings, further physiologic and psychologic research studies in spinal cord injury patients should lead to more rational management strategies for the common gastrointestinal symptoms in spinal cord injury.

High-definition endoscopy systems provide superior image resolution. The aim of this study was to assess the utility of high definition compared with standard definition endoscopy system for detecting dysplastic lesions in patients with Barrett's esophagus. A retrospective cohort study of patients with non-dysplastic Barrett's esophagus undergoing routine surveillance was performed. Data were retrieved from the central hospital electronic database. Procedures performed for non-surveillance indications, Barrett's esophagus Prague C0M1 classification with no specialized intestinal metaplasia on histology, patients diagnosed with any dysplasia or cancer on index endoscopy, and procedures using advanced imaging techniques were excluded. Logistic regression models were constructed to estimate adjusted odds ratios and 95% confidence intervals comparing outcomes with standard definition and high-definition systems. The high definition was superior to standard definition system in targeted detection of all dysplastic lesions (odds ratio 3.27, 95% confidence interval 1.27-8.40) as well as overall dysplasia detected on both random and target biopsies (odds ratio 2.36, 95% confidence interval 1.50-3.72). More non-dysplastic lesions were detected with the high-definition system (odds ratio 1.16, 95% confidence interval 1.01-1.33). There was no difference between high definition and standard definition endoscopy in the overall (random and target) high-grade dysplasia or cancers detected (odds ratio 0.93, 95% confidence interval 0.83-1.04). Trainee endoscopists, number of biopsies taken, and male sex were all significantly associated with a higher yield for dysplastic lesions. The use of the high-definition endoscopy system is associated with better targeted detection of any dysplasia during routine Barrett's esophagus surveillance. However, high-definition endoscopy cannot replace random biopsies at present time. © 2014 International Society for Diseases of the Esophagus.

Risk factors for the development of new-onset late postpartum preeclampsia (LPP) in women without any history of preeclampsia are not known. Because identification of women who are at risk may lead to an earlier diagnosis of disease and improved maternal outcomes, this study identified risk factors (associated patient characteristics) for new-onset LPP. A case-control study of 34 women with new-onset LPP and 68 women without new-onset LPP after normal delivery, who were matched on date of delivery, was conducted at Mount Sinai Hospital, New York, NY. Data were collected by chart review. Exact conditional logistic regression identified patient characteristics that were associated with new-onset LPP. New-onset LPP was associated with age ≥40 years (adjusted odds ratio, 24.83; 95% confidence interval [CI], 1.43-infinity; P = .03), black race (adjusted odds ratio, 78.35; 95% CI, 7.25-infinity; P < .001), Latino ethnicity (adjusted odds ratio, 19.08; 95% CI, 2.73-infinity; P = .001), final pregnancy body mass index of ≥30 kg/m(2) (adjusted odds ratio, 13.38; 95% CI, 1.87-infinity; P = .01), and gestational diabetes mellitus (adjusted odds ratio, 72.91; 95% CI, 5.52-infinity; P < .001). As predictive tests for new-onset LPP, the sensitivity and specificity of having ≥1 of these characteristics was 100% and 59%, respectively, and the sensitivity and specificity of having ≥2 was 56% and 93%, respectively. Older age, black race, Latino ethnicity, obesity, and a pregnancy complicated by gestational diabetes mellitus all are associated positively with the development of new-onset LPP. Closer observation may be warranted in these populations. Copyright © 2014 Mosby, Inc. All rights reserved.

Although published reports about technical management of massive weight loss patients are beginning to appear, risk factors for complications following body contouring operations are not known. A retrospective analysis of massive weight loss patients who had body contouring operations between March of 1998 and October of 2004 was performed. Demographic and surgical factors were analyzed. Outcome measures included seroma, wound dehiscence, thromboembolic complications, blood transfusion after surgery, and extended lengths of stay (>2 days). A total of 139 patients were analyzed; 82.7 percent of them were female; mean age was 41 years. On multiple logistic regression, male gender was associated with significant risks for wound dehiscence (odds ratio, 6.4; p = 0.01). There were also trends toward increased risk for wound dehiscence with hypothyroidism (odds ratio, 4.3; p = 0.06) and Ehlers-Danlos syndrome (odds ratio, 18.7; p = 0.05). In terms of risk of blood transfusion, asthma and having three or more procedures were the two variables that emerged with significant association (odds ratio, 16.8 and 13.7, respectively; both p < 0.01). Increased length of stay to greater than 2 days was also significantly associated with having three or more procedures (odds ratio, 4.72; p < 0.01). Male gender, hypothyroidism, and Ehlers-Danlos syndrome may be risk factors for wound dehiscence following body contour operations for massive weight loss. Asthma may be a marker of poor general health status, and asthmatic patients are at increased risk for requiring blood transfusions. Having three or more procedures is associated with an increased risk of blood transfusion and increased length of stay.

Do doctors vote?

Organizational leaders and scholars have issued calls for the medical profession to refocus its efforts on fulfilling the core tenets of professionalism. A key element of professionalism is participation in community affairs. To measure physician voting rates as an indicator of civic participation. Cross-sectional survey of a subgroup of physicians from a nationally representative household survey of civilian, noninstitutionalized adult citizens. A total of 350,870 participants in the Current Population Survey (CPS) November Voter Supplement from 1996-2002, including 1,274 physicians and 1,886 lawyers; 414,989 participants in the CPS survey from 1976-1982, including 2,033 health professionals. Multivariate logistic regression models were used to compare adjusted physician voting rates in the 1996-2002 congressional and presidential elections with those of lawyers and the general population and to compare voting rates of health professionals in 1996-2002 with those in 1976-1992. After multivariate adjustment for characteristics known to be associated with voting rates, physicians were less likely to vote than the general population in 1998 (odds ratio 0.76; 95% confidence interval [CI] 0.59-0.99), 2000 (odds ratio 0.64; 95% CI 0.44-0.93), and 2002 (odds ratio 0.62; 95% CI 0.48-0.80) but not 1996 (odds ratio 0.83; 95% CI 0.59-1.17). Lawyers voted at higher rates than the general population and doctors in all four elections (P < .001). The pooled adjusted odds ratio for physician voting across the four elections was 0.70 (CI 0.61-0.81). No substantial changes in voting rates for health professionals were observed between 1976-1982 and 1996-2002. Physicians have lower adjusted voting rates than lawyers and the general population, suggesting reduced civic participation.

Smoking and obesity might alter the risk of sarcoidosis. However, the data remained inconclusive. A cohort of Olmsted County, Minnesota residents diagnosed with sarcoidosis between January 1, 1976 and December 31, 2013 was identified based on individual medical record review. For each sarcoidosis subject, one sex and aged-matched control without sarcoidosis was randomly selected from the same underlying population. Medical records of cases and controls were reviewed for smoking status at index date and body mass index (BMI) within 1 year before to 3 months after index date. 345 incident cases of sarcoidosis and 345 controls were identified. The odds ratio of sarcoidosis comparing current smokers with never smokers adjusted for age and sex was 0.34 (95% confidence interval (CI), 0.23-0.50). The odds ratio of sarcoidosis comparing current smokers with never smokers and former smokers adjusted for age and sex was 0.38 (95% CI, 0.26-0.56). The odds ratio of sarcoidosis comparing overweight subjects (BMI ≥ 25 kg/m 2 but < 30 kg/m 2 ) with subjects with normal/low BMI was 1.12 (95% CI, 0.72-1.75). The odds ratio of sarcoidosis comparing obese subjects (BMI ≥ 30 kg/m 2 ) with subjects with normal/low BMI was 2.54 (95% CI, 1.58-4.06). The odds ratio of sarcoidosis comparing obese subjects with non-obese subjects was 2.38 (95% CI, 1.60-3.56). In this population, current smokers have a lower risk of developing sarcoidosis while subjects with obesity have a higher risk of developing sarcoidosis. Copyright © 2016 Elsevier Ltd.

The relationship between alcohol intake and rectal cancer is uncertain. We sought to evaluate whether alcohol consumption is associated with distal colorectal cancer and rectal cancer specifically. Data on alcohol intake were examined from the North Carolina Colon Cancer Study, a population-based case-control study of distal colorectal cancer. This study encompassed 33 counties in the central and eastern part of North Carolina. Cases had adenocarcinoma of the rectum, rectosigmoid, and sigmoid colon. Controls were frequency-matched on age, race, and sex. Demographic and dietary intake data were collected with use of a validated questionnaire. Logistic regression was used to estimate odds ratios for the relationship between alcohol consumption and distal colorectal cancer. Included in the study were 1033 cases and 1011 controls. The odds ratio for rectal cancer comparing any vs no alcohol intake was 0.73 (95% CI 0.60, 0.90), adjusted for age, sex, race, smoking status, obesity, education, red meat intake, use of nonsteroidal anti-inflammatory medications, and family history of colorectal cancer. The odds ratio for moderate alcohol (≤14 g/day) was 0.66 (95% CI 0.53, 0.82), whereas the odds ratio for heavy alcohol (>14 g/day) was 0.93 (95% CI 0.70, 1.23). Moderate beer and wine intakes were also inversely associated with distal colorectal cancer: odds ratios 0.76 (95% CI 0.60, 0.96) and 0.69 (95% CI 0.56, 0.86). This was a retrospective, observational study. Residual confounding is possible. In this study, moderate alcohol intake (especially wine) was inversely associated with distal colorectal cancer.

We evaluated patients with chronic hepatitis C (CHC) and compared the clinical and pathological features of steatosis and metabolic syndrome to identify the risk factors for CHC with severe fibrosis. One hundred seventy-one patients with biopsy-confirmed CHC were included in the study: 90 males and 81 females, age 56.2 ± 12.8 years; 46 with obesity (BMI≥25 kg/m(2)); 51 with hypertension; 36 with type 2 diabetes mellitus; and 20 with hypertriglyceridemia. Steatosis was detected in 79 patients (46%); 92 patients (54%) showed no steatosis. Seventy-four patients (43%) showed mild fibrosis and 97 patients (56%) showed severe fibrosis. The variables that were significantly associated with steatosis were obesity [odds ratio 2.160 (1.010-4.727), p=0.046] and type 2 diabetes [odds ratio 3.667 (1.559-8.430), p=0.027]. The variables that were significantly associated with severe fibrosis were older age [odds ratio 2.675 (1.309-5.464), p=0.007], obesity [odds ratio 2.156 (1.006-4.619), p=0.048] and type 2 diabetes [odds ratio 8.739 (2.845-26.846), p=0.0002]. Nagasaki (N) score (the total number of specific risk factors, namely an older age, obesity, and type 2 diabetes) was higher in the severe fibrosis group than in the mild fibrosis group (mild fibrosis: severe fibrosis=1.48 ± 1.14 vs.2.66 ± 94, p<0.001). Metabolic syndrome factors, including obesity and diabetes, play a critical role in the pathogenesis of fibrosis in CHC. The N score was therefore found to be a significant predictor of severe fibrosis in CHC.

Recreational physical inactivity has been gaining recognition as an independent epidemiological exposure of interest in relation to cancer endpoints due to evidence suggesting that it may associate with cancer independent of obesity. In the current analyses, we examined the associations of lifetime recreational physical inactivity with renal and bladder cancer risk. In this hospital-based case-control study, we identified N=160 renal cancer patients, N=208 bladder cancer patients, and N=766 age frequency-matched controls without cancer. Participants self-reporting never participating in any regular/weekly recreational physical activity throughout their lifetime were classified as physically inactive. Utilizing unconditional multivariable logistic regression analyses, we estimated odds ratios and 95% confidence intervals to represent the associations between lifetime physical inactivity and renal and bladder cancer risk. In multivariable logistic regression models, we observed significant positive associations between lifetime recreational physical inactivity and renal cancer and bladder cancer risk: odds ratio=1.77 (95% CI: 1.10-2.85) and odds ratio=1.73 (95% CI: 1.13-2.63), respectively. Similar associations also persisted among individuals who were not obese for both renal and bladder cancer: odds ratio=1.75 (95% CI: 1.03-2.98) and odds ratio=1.70 (95% CI: 1.08-2.69), respectively. In this case-control study, we observed evidence of a positive association between renal and bladder cancer with lifetime recreational physical inactivity. These data add to the growing body of evidence suggesting that physical inactivity may be an important independent risk factor for cancer. However, additional studies using a larger sample and prospectively collected data are needed to substantiate the current findings. Copyright © 2017 Elsevier Ltd. All rights reserved.

Physical inactivity is the fourth leading cause of death worldwide. Increase in physical activity decreases the incidence of cardiovascular diseases, Type 2 diabetes, stroke, and improves psychological wellbeing. To study the level of physical inactivity among the adult population in an urban area of Puducherry in India and its associated risk factors. This cross-sectional study was conducted among 569 adult participants from an urban area of Pondicherry. The level of physical inactivity was measured by using WHO standard Global Physical Activity Questionnaire (GPAQ). Overall prevalence of physical inactivity in our study was 49.7% (CI: 45.6-53.8). Among the physically active people, contribution of physical activity by work was 77.4%, leisure time activities were 11.6% and transport time was 11%. Both men and women were equally inactive {Physically inactive among women was 50% (CI:44.1-55.9)} and {Physically inactive among men was 49.5% (CI:43.8-55.2)}. Prevalence of physical inactivity was increasing with increasing age. Non tobacco users were two times more active than tobacco users {Adjusted Odds Ratio: 2.183 (1.175- 4.057)}. Employed were more active as compared to retired {Adjusted Odds Ratio: 0.412 (0.171-0.991)}, students {Adjusted Odds Ratio: 0.456 (0.196-1.060)}, house wives {Adjusted Odds Ratio: 0.757 (0.509-1.127)} and unemployed {Adjusted Odds Ratio: 0.538 (0.271-1.068)}. Non alcoholics were only 0.34 times as active as alcoholics. Level of physical activity was found to be insufficient among adult urban population of Puducherry. Working adult population found to be active, that too due to their work pattern. There is a need to promote leisure time and travelling time physical activity.

Concern exists that plastic surgeons are performing fewer autologous and microsurgical breast reconstructions, despite superior long-term outcomes. The authors describe the proportion of U.S. plastic surgeons performing these procedures and evaluate motivating factors and perceived barriers. A random national sample of American Society of Plastic Surgeons members was surveyed (n = 325; response rate, 76 percent). Surgeon and practice characteristics were assessed, and two multiple logistic regression models were created to evaluate factors associated with (1) high-volume autologous providers and (2) microsurgical providers. Qualitative assessments of motivating factors and barriers to microsurgery were also performed. Fewer than one-fifth of plastic surgeons perform autologous procedures for more than 50 percent of their breast cancer patients, and only one-quarter perform any microsurgical breast reconstruction. Independent predictors of a high-volume autologous practice include involvement with resident education (odds ratio, 2.57; 95 percent CI, 1.26 to 5.24) and a microsurgical fellowship (odds ratio, 2.09; 95 percent CI, 1.04 to 4.27). Predictors of microsurgical breast reconstruction include involvement with resident education (odds ratio, 6.8; 95 percent CI, 3.32 to 13.91), microsurgical fellowship (odds ratio, 2.4; 95 percent CI, 1.16 to 4.95), and high breast reconstruction volume (odds ratio, 6.68; 95 percent CI, 1.76 to 25.27). The primary motivator for microsurgery is superior outcomes, and the primary deterrents are time and reimbursement. The proportion of U.S. plastic surgeons with a high-volume autologous or microsurgical breast reconstruction practice is low. Involvement with resident education appears to facilitate both, whereas time constraints and reimbursement are primary deterrents. Future efforts should focus on improving the feasibility and accessibility of all types of breast reconstruction.

Excessive sun exposure during childhood is a risk factor for skin cancer. This study aimed to compare the frequency of ideal sun protection use between parents with lighter- and darker-skinned children and explore their attitudes and beliefs on sun safety and their choice of sun protection. Parents of children aged 6 months to 6 years completed self-administered questionnaires about sun protection practices for their children. Parents assessed their child's Fitzpatrick phototype and were divided into lighter- (Fitzpatrick phototype I-III) and darker-skinned (Fitzpatrick phototype IV-VI) groups. Sun safety guidelines from the Canadian Dermatology Association were used to qualify ideal sun protection. A total of 183 parents were included. Overall, 31 parents (17%) used ideal sun protection for their children. As their children grew older, parents were less likely to use ideal sun protection (odds ratio = 0.69, 95% confidence interval = 0.53-0.90). Parents in the lighter-skinned group were more likely to use ideal sun protection for their children (odds ratio = 7.4, 95% confidence interval = 2.7-20.1), believe that sun exposure was harmful (odds ratio = 17.2, 95% confidence interval = 4.0-74.9), and perceive value in sun protection (odds ratio = 11.4, 95% confidence interval = 3.3-39.0); the darker-skinned group believed that darker skin tones provided more sun protection (odds ratio = 12.4, 95% confidence interval = 6.1-25.4). Ideal parental sun protection efforts are overall low, particularly in parents of darker-skinned children. The identified attitudes toward and beliefs about sun safety may aid in delivery of future sun protection interventions, especially in multiracial populations. © 2018 Wiley Periodicals, Inc.

OBJECTIVES: To investigate the relation between residential exposure to radon and lung cancer. METHODS: A literature search was performed using Medline and other sources. The quality of studies was assessed. Adjusted odds ratios with 95% confidence intervals (CI) for the risk of lung cancer among categories of levels of exposure to radon were extracted. For each study, a weighted log-linear regression analysis of the adjusted odds ratios was performed according to radon concentration. The random effect model was used to combine values from single studies. Separate meta-analyses were performed on results from studies grouped with similar characteristics or with quality scores above or equal to the median. FINDINGS: Seventeen case-control studies were included in the meta-analysis. Quality scoring for individual studies ranged from 0.45 to 0.77 (median, 0.64). Meta-analysis based on exposure at 150 Bq/m3 gave a pooled odds ratio estimate of 1.24 (95% CI, 1.11-1.38), which indicated a potential effect of residential exposure to radon on the risk of lung cancer. Pooled estimates of fitted odds ratios at several levels of randon exposure were all significantly different from unity--ranging from 1.07 at 50 Bq/m3 to 1.43 at 250 Bq/m3. No remarkable differences from the baseline analysis were found for odds ratios from sensitivity analyses of studies in which > 75% of eligible cases were recruited (1.12, 1.00-1.25) and studies that included only women (1.29, 1.04-1.60). CONCLUSION: Although no definitive conclusions may be drawn, our results suggest a dose-response relation between residential exposure to radon and the risk of lung cancer. They support the need to develop strategies to reduce human exposure to radon. PMID:14758433

Classic Hodgkin lymphoma (cHL) has few known modifiable risk factors, and the relationship between diet and cHL risk is unclear. We performed the first investigation of an association between dietary pattern and cHL risk in 435 cHL cases and 563 population-based controls from Massachusetts and Connecticut (1997–2000) who completed baseline diet questionnaires. We identified 4 major dietary patterns (“vegetable,” “high meat,” “fruit/low-fat dairy,” “desserts/sweets”) using principal components analysis. We computed multivariable odds ratios and 95% confidence intervals for associations of dietary pattern score (quartiles) with younger-adult (age <50 years), older-adult (age ≥50 years), and overall cHL risk. Secondary analyses examined associations by histological subtype and tumor Epstein-Barr virus (EBV) status. A diet high in desserts/sweets was associated with younger-adult (odds ratio(quartile 4 vs. quartile 1) = 1.60, 95% confidence interval: 1.05, 2.45; Ptrend = 0.008) and EBV-negative, younger-adult (odds ratio = 2.11, 95% confidence interval: 1.31, 3.41; Ptrend = 0.007) cHL risk. A high meat diet was associated with older-adult (odds ratio = 3.34, 95% confidence interval: 1.02, 10.91; Ptrend = 0.04) and EBV-negative, older-adult (odds ratio = 4.64, 95% confidence interval: 1.03, 20.86; Ptrend = 0.04) cHL risk. Other dietary patterns were not clearly associated with cHL. We report the first evidence for a role of dietary pattern in cHL etiology. Diets featuring high intake of meat or desserts and sweets may increase cHL risk. PMID:26182945

This study was designed to assess the efficiency of the serum thyrotropin to thyroglobulin ratio for thyroid nodule evaluation in euthyroid patients. Cross-sectional study. Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China. Retrospective analysis was performed for 400 previously untreated cases presenting with thyroid nodules. Thyroid function was tested with commercially available radioimmunoassays. The receiver operating characteristic curves were constructed to determine cutoff values. The efficacy of the thyrotropin:thyroglobulin ratio and thyroid-stimulating hormone for thyroid nodule evaluation was evaluated in terms of sensitivity, specificity, positive predictive value, positive likelihood ratio, negative likelihood ratio, and odds ratio. In receiver operating characteristic curve analysis, the area under the curve was 0.746 for the thyrotropin:thyroglobulin ratio and 0.659 for thyroid-stimulating hormone. With a cutoff point value of 24.97 IU/g for the thyrotropin:thyroglobulin ratio, the sensitivity, specificity, positive predictive value, positive likelihood ratio, and negative likelihood ratio were 78.9%, 60.8%, 75.5%, 2.01, and 0.35, respectively. The odds ratio for the thyrotropin:thyroglobulin ratio indicating malignancy was 5.80. With a cutoff point value of 1.525 µIU/mL for thyroid-stimulating hormone, the sensitivity, specificity, positive predictive value, positive likelihood ratio, and negative likelihood ratio were 74.0%, 53.2%, 70.8%, 1.58, and 0.49, respectively. The odds ratio indicating malignancy for thyroid-stimulating hormone was 3.23. Increasing preoperative serum thyrotropin:thyroglobulin ratio is a risk factor for thyroid carcinoma, and the correlation of the thyrotropin:thyroglobulin ratio to malignancy is higher than that for serum thyroid-stimulating hormone. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

This study investigates the importance of sociodemographic and geographical characteristics for suicide risks in the South African urban context. Suicide epidemiology is under-researched in low- and middle-income countries, and such knowledge is important not only for local and national policy, but also for a global understanding of the phenomenon. Sex-specific crude and adjusted odds ratios (95% confidence intervals) for suicide by age, race, and city are assessed using logistic regression. Cases aged 45+ years, classified as "Coloured" (a category denoting mixed racial origin), and living in Cape Town are used as reference groups. Additionally, the proportion of leading suicide methods within groups was estimated (95% confidence intervals). For males, compared with each reference group, the odds of suicide are significantly higher during middle adulthood, among Asians and particularly among Whites, and among residents of all but one city. Patterns for women differ in magnitude and distribution. Suicide odds are significantly higher in all age groups, particularly 15-24 years, among Whites, and among residents of all other cities, particularly Nelson Mandela or Buffalo City. Males living in Tshwane and Black females have lower odds of suicide. The distribution of methods across age, race, and city groups varies little for males but substantially for females. Age, race, and city play independent roles in sex-specific suicide rates. As for high-income settings, age, race, method and city are important in sex-specific suicide in the urban South African context. Possible underlying mechanisms deserve greater attention for context-relevant preventive efforts.

To determine rates and types of peripartum morbidity among delivering women with spina bifida (SB) compared to those without SB. The rates of pregnancy and delivery among women with SB have been significantly increasing. Current knowledge of peripartum outcomes for these women is limited. Using 2004-2013 National Inpatient Sample data, we identified all hospitalizations for delivery, distinguishing between women with and without SB. Using a code-based algorithm, we determined whether a complication occurred during the hospitalization. We then fit a series of multivariable logistic models to examine for associations between a complication occurrence during vaginal or cesarean delivery and a woman's SB status. We identified 38,319,814 weighted admissions for delivery, 9,516 of which were made by women with SB. Women with SB had a significantly higher rate of cesarean delivery than women without this diagnosis (53% v 32%, p<0.001). The 46.7% of women with SB who delivered vaginally did not have significantly increased odds of a complication associated with their delivery compared to women without SB [odds ratio (OR) 1.15, 95% confidence interval (CI) 0.99 to 1.34, p=0.066]. However, women with SB who underwent a cesarean delivery did have higher odds of morbidity compared to those without (OR 1.49, 95% CI 1.25 to 1.78, p<0.001). Common complications included preterm delivery, urinary tract infection, hematologic event, and blood transfusion. Compared to women without SB, those with SB deliver more frequently by cesarean section and have higher odds of morbidity associated with cesarean delivery, but not vaginal delivery.

Although some sociologists have suggested that Japanese Americans quickly assimilated into mainstream America, scholars of Japanese America have highlighted the heightened exclusion that the group experienced. This study tracked historical shifts in the exclusion level of Japanese and Japanese Americans in the United States surrounding World War II with homogamy and intermarriage with Whites for the prewar (1930–1940) and resettlement (1946–1966) marriage cohorts. The authors applied log-linear models to census microsamples (N = 1,590,416) to estimate the odds ratios of homogamy versus intermarriage. The unadjusted odds ratios of Japanese Americans declined between cohorts and appeared to be consistent with the assimilation hypothesis. Once compositional influences and educational pairing patterns were adjusted, however, the odds ratios increased and supported the heightened exclusion hypothesis. PMID:21116449

Strongylus vulgaris is a pathogenic helminth parasite infecting horses and was once considered to be the primary cause of colic. Migrating larvae cause ischaemia and infarction of intestinal segments. This knowledge is derived from case reports and experimental inoculations of parasite-naïve foals, and it remains unknown to what extent the parasite is associated with different types of colic. To evaluate the role of S. vulgaris as a risk factor for different types of colic in horses. A retrospective case-control study among horses referred with abdominal pain to the University of Copenhagen Large Animal Teaching Hospital during 2009-2011. Each colic case was matched with an equid of the same type (pony, Warmblooded or Coldblooded), age, sex and admitted in the same month and year but for problems unrelated to the gastrointestinal tract. Serum samples were analysed for antibodies to migrating S. vulgaris larvae using a recently developed enzyme-linked immunosorbent assay (ELISA). The following 4 case definitions were used: colic sensu lato, i.e. all horses presenting with colic (n = 274), with further subgroups, i.e. undiagnosed colics (n = 48), strangulating obstructions (n = 76) and nonstrangulating infarctions (n = 20). Strongylus vulgaris antibody levels were similar to control values in colics sensu lato and horses with undiagnosed colic. In contrast, nonstrangulating intestinal infarctions were significantly associated with positive S. vulgaris ELISAs (odds ratio 5.33, 95% confidence interval 1.03-27.76, P = 0.05). Also, horses with nonstrangulating infarctions had a significantly higher occurrence of positive ELISAs than horses with strangulating obstructions (odds ratio 3.79, 95% confidence interval 1.34-10.68, P = 0.01) and the colic sensu lato group (odds ratio 3.09, 95% confidence interval 1.20-8.01, P = 0.02). Nonstrangulating intestinal infarction was strongly associated with S. vulgaris-specific antibodies, whereas the more broadly defined colic categories were not associated with positive ELISA results. Thus, the ELISA holds potential to become a helpful adjunct in diagnosis and management of horses with colic. © 2015 EVJ Ltd.

Hospital readmission rates following surgery are increasingly being used as a marker of quality of care and are used in pay-for-performance metrics. To our knowledge, comprehensive data on readmissions to the initial hospital or a different hospital after emergency general surgery (EGS) procedures do not exist. To define readmission rates and identify risk factors for readmission after common EGS procedures. Patients undergoing EGS, as defined by the American Association for the Surgery of Trauma, were identified in the California State Inpatient Database (2007-2011) on January 15, 2015. Patients were 18 years and older. We identified the 5 most commonly performed EGS procedures in each of 11 EGS diagnosis groups. Patient demographics (sex, age, race/ethnicity, and insurance type) as well as Charlson Comorbidity Index score, length of stay, complications, and discharge disposition were collected. Factors associated with readmission were determined using multivariate logistic regression models analysis. Thirty-day hospital readmission. Among 177,511 patients meeting inclusion criteria, 57.1% were white, 48.8% were privately insured, and most were 45 years and older (51.3%). Laparoscopic appendectomy (35.2%) and laparoscopic cholecystectomy (19.3%) were the most common procedures. The overall 30-day readmission rate was 5.91%. Readmission rates ranged from 4.1% (upper gastrointestinal) to 16.8% (cardiothoracic). Of readmitted patients, 16.8% were readmitted at a different hospital. Predictors of readmission included Charlson Comorbidity Index score of 2 or greater (adjusted odds ratio: 2.26 [95% CI, 2.14-2.39]), leaving against medical advice (adjusted odds ratio: 2.24 [95% CI, 1.89-2.66]), and public insurance (adjusted odds ratio: 1.55 [95% CI, 1.47-1.64]). The most common reasons for readmission were surgical site infections (16.9%), gastrointestinal complications (11.3%), and pulmonary complications (3.6%). Readmission after EGS procedures is common and varies widely depending on patient factors and diagnosis categories. One in 5 readmitted patients will go to a different hospital, causing fragmentation of care and potentially obscuring the utility of readmission as a quality metric. Assisting socially vulnerable patients and reducing postoperative complications, including infections, are targets to reduce readmissions.

Determinants of children's school wellbeing have not been extensively studied. In this cross-sectional study of school children we assessed how factors assumed to promote wellbeing and factors assumed to adversely influence wellbeing were associated with self-reported wellbeing in school. Children from five schools, 230 boys and 189 girls in grades 1-10, responded to the same set of questions. We used proportional odds logistic regression to assess the associations of promoting and restraining factors with school wellbeing. In a multivariable analysis, degree of school wellbeing in boys was strongly and positively related to enjoying school work (odds ratio, 3.84, 95% CI 2.38 to 6.22) and receiving necessary help (odds ratio, 3.55, 95% CI 2.17 to 5.80) from teachers. In girls, being bothered during lessons was strongly and negatively associated with school wellbeing (odds ratio, 0.43, 95% CI 0.22 to 0.85). Different factors may determine school wellbeing in boys and girls, but for both genders, factors relevant for lessons may be more important than factors related to recess. Especially in boys, the student-teacher relationship may be of particular importance.

Many studies have addressed the question of whether mental disorder is associated with creativity, but high-quality epidemiological evidence has been lacking.AimsTo test for an association between studying a creative subject at high school or university and later mental disorder. In a case-control study using linked population-based registries in Sweden (N = 4 454 763), we tested for associations between tertiary education in an artistic field and hospital admission with schizophrenia (N = 20 333), bipolar disorder (N = 28 293) or unipolar depression (N = 148 365). Compared with the general population, individuals with an artistic education had increased odds of developing schizophrenia (odds ratio = 1.90, 95% CI = [1.69; 2.12]) bipolar disorder (odds ratio = 1.62 [1.50; 1.75]) and unipolar depression (odds ratio = 1.39 [1.34; 1.44]. The results remained after adjustment for IQ and other potential confounders. Students of artistic subjects at university are at increased risk of developing schizophrenia, bipolar disorder and unipolar depression in adulthood.Declaration of interestNone.

We have investigated the mid-infrared spectral characteristics of a series of polycyclic aromatic hydrocarbons (PAHs) with straight edges and containing an even or odd number of carbons using density functional theory (DFT). For several even and odd-carbon PAHs, the 8.6/6.2 and 7.6/6.2 intensity ratios computed in emission after the absorption of a 8 eV photon match the observed ratios obtained for three reflection nebulae (RNe), namely NGC 1333, NGC 7023, and NGC 2023. Odd-carbon PAHs are favored, particularly for NGC 1333. Both cations and anions are present with the cations being predominant. Relevant PAHs span sizes ranging from 46 to 103-113 carbons for NGC 7023 and NGC 2023 and from 38 to 127 carbons for NGC 1333 and have symmetries ranging from D 2 h to C s . Our work suggests that even and odd-carbon PAHs with straight edges are viable candidates for the PAH emission seen towards irradiated Photo-Dissociation Regions (PDRs).

Knowledge regarding the health-related quality of life (HRQoL) of children with celiac disease remains limited and inconclusive. We investigated the HRQoL of three groups of 12-year-olds with: i) undetected celiac disease ii) clinically diagnosed celiac disease, and iii) without celiac disease. A school-based cross-sectional multicenter screening study invited 18 325 children, whereof 68% consented to participate. Participants provided a blood sample, which was later analyzed for anti-tissue-tranglutaminase antibodies, and alongside filled in a questionnaire. When anti-tissue-tranglutaminase antibodies were elevated, a small intestinal biopsy verified the screening-detected celiac disease diagnosis. Self-reported HRQoL was measured using Kidscreen, a generic 52 items instrument with proven reliability and validity. Scores were linearly transformed into a 0-100 scale with higher values indicating better HRQoL. Mean values with standard deviations (mean ± SD) were compared, and uni- and multivariate logistic regression models tested the odds of a low HRQoL among children with undetected or diagnosed celiac disease, respectively. Children with undetected celiac disease (n = 238) reported similar HRQoL as children without celiac disease (n = 12 037) (83.0 ± 11.0 vs. 82.5 ± 11.3, P = 0.51), and also similar HRQoL (82.2 ± 12.2, P = 0.28) to that of children with diagnosed celiac disease (n = 90), of whom 92% were adherent to treatment. Having undetected celiac disease did not increase the odds of low overall HRQoL, independent of sex, area of residence, study year and occurrence of gastrointestinal symptoms (adjusted odds ratio 0.77, 95% CI 0.54-1.10). Comparable results were seen for diagnosed celiac disease cases (adjusted odds ratio 1.11, 95% CI 0.67-1.85). Children with undetected celiac disease reported comparable HRQoL as their peers with diagnosed celiac disease, and those without celiac disease, when reporting prior to receiving the diagnosis through screening. Thus, children with celiac disease, both untreated and diagnosed, perceive their HRQoL as unimpaired by their disease.

Research to date on the effect vehicle-ride exposure has on the development of cervical pathologies in mounted Warfighters is conflicting. The purpose of this study was to determine if the literature suggests a definite effect of vehicle-ride exposure on cervical pathology. Databases were searched using multiple combinations of select terms. Twelve studies meeting the inclusion criteria were included in the meta-analysis. The results of the meta-analysis revealed that overall vehicle-ride exposure was likely to increase cervical pathology (p=0.01, odds ratio=1.59, 95% CI=1.16−2.17). Using vehicle type as a moderator it was found that vehicle-ride exposure in ground-based vehicles (p=0.01, odds ratio=2.33, 95% CI=1.41−3.85) and fixed-wing aircraft (p=0.01, odds ratio =1.59, 95% CI=1.13−2.23) were likely to increase cervical pathology. Using operator/other personnel moderator it was found that in the populations tested, fighter pilots or fighter jet weapons systems operators were more likely to develop a cervical pathology (p<0.001, odds ratio=1.78, 95% CI=1.26−2.50). The available studies indicate an increase in cervical pathology for personnel exposed to ground-based vehicles and fixed-wing aircraft. PMID:25739897

Whether intravenous thrombolysis adds a further benefit when given before endovascular thrombectomy (EVT) is unknown. Furthermore, intravenous thrombolysis delays time to groin puncture, mainly among drip and ship patients. Using region-wide registry data, we selected cases that received direct EVT or combined intravenous thrombolysis+EVT for anterior circulation strokes between January 2011 and October 2015. Treatment effect was estimated by stratification on a propensity score. The average odds ratios for the association of treatment with good outcome and death at 3 months and symptomatic bleedings at 24 hours were calculated with the Mantel-Haenszel test statistic. We included 599 direct EVT patients and 567 patients with combined treatment. Stratification through propensity score achieved balance of baseline characteristics across treatment groups. There was no association between treatment modality and good outcome (odds ratio, 0.97; 95% confidence interval, 0.74-1.27), death (odds ratio, 1.07; 95% confidence interval, 0.74-1.54), or symptomatic bleedings (odds ratio, 0.56; 95% confidence interval, 0.25-1.27). This observational study suggests that outcomes after direct EVT or combined intravenous thrombolysis+EVT are not different. If confirmed by a randomized controlled trial, it may have a significant impact on organization of stroke systems of care. © 2017 American Heart Association, Inc.

Multiple control groups in case-control studies are used to control for different sources of confounding. For example, cases can be contrasted with matched controls to adjust for multiple genetic or unknown lifestyle factors and simultaneously contrasted with an unmatched population-based control group. Inclusion of different control groups for a single exposure analysis yields several estimates of the odds ratio, all using only part of the data. Here the authors introduce an easy way to combine odds ratios from several case-control analyses with the same cases. The approach is based upon methods used for meta-analysis but takes into account the fact that the same cases are used and that the estimated odds ratios are therefore correlated. Two ways of estimating this correlation are discussed: sandwich methodology and the bootstrap. Confidence intervals for the pooled estimates and a test for checking whether the odds ratios in the separate case-control studies differ significantly are derived. The performance of the method is studied by simulation and by applying the methods to a large study on risk factors for thrombosis, the MEGA Study (1999-2004), wherein cases with first venous thrombosis were included with a matched control group of partners and an unmatched population-based control group.

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

The objective of the study was to determine if female workers in a heavy manufacturing environment have a higher risk of injury compared with males when performing the same job and to evaluate sex differences in type or severity of injury. By use of human resources and incident surveillance data for the hourly population at 6 US aluminum smelters, injuries that occurred from January 1, 1996, through December 21, 2005, were analyzed. Multivariate logistic regression, adjusted for job, tenure, and age category, was used to calculate odds ratios and 95% confidence intervals for female versus male injury risk for all injuries, recordable injuries, and lost work time injuries. The analysis was repeated for acute injuries and musculoskeletal disorder-related injuries separately. Female workers in this industry have a greater risk for sustaining all forms of injury after adjustment for age, tenure, and standardized job category (odds ratio = 1.365, 95% confidence interval: 1.290, 1.445). This excess risk for female workers persisted when injuries were dichotomized into acute injuries (odds ratio = 1.2) and musculoskeletal disorder-related injuries (odds ratio = 1.1). This study provides evidence of a sex disparity in occupational injury with female workers at higher risk compared with their male counterparts in a heavy manufacturing environment.

Objectives Individual participant data (IPD) meta-analyses often analyze their IPD as if coming from a single study. We compare this approach with analyses that rather account for clustering of patients within studies. Study Design and Setting Comparison of effect estimates from logistic regression models in real and simulated examples. Results The estimated prognostic effect of age in patients with traumatic brain injury is similar, regardless of whether clustering is accounted for. However, a family history of thrombophilia is found to be a diagnostic marker of deep vein thrombosis [odds ratio, 1.30; 95% confidence interval (CI): 1.00, 1.70; P = 0.05] when clustering is accounted for but not when it is ignored (odds ratio, 1.06; 95% CI: 0.83, 1.37; P = 0.64). Similarly, the treatment effect of nicotine gum on smoking cessation is severely attenuated when clustering is ignored (odds ratio, 1.40; 95% CI: 1.02, 1.92) rather than accounted for (odds ratio, 1.80; 95% CI: 1.29, 2.52). Simulations show models accounting for clustering perform consistently well, but downwardly biased effect estimates and low coverage can occur when ignoring clustering. Conclusion Researchers must routinely account for clustering in IPD meta-analyses; otherwise, misleading effect estimates and conclusions may arise. PMID:23651765

Endometrial spotting or bleeding is a common adverse effect among women taking continuous-combined estrogen-progestin therapy. The renin-angiotensin-aldosterone system plays a major role in hypertension and is present in the endometrium. We hypothesized that postmenopausal women with hypertension would have a higher incidence of bleeding compared with postmenopausal women without hypertension. A multivariate mixed-effects logistic model estimated the odds ratios for the relationship of hypertension status or use of antihypertensive drugs with endometrial bleeding using the Women's Health Initiative database. The incidence of spotting or bleeding in the first 12 months of estrogen-progestin use was 42% in women aged 50 to 79 years. Women with hypertension were more likely to experience bleeding than women without hypertension (odds ratio, 1.07; 95% CI, 1.02-1.13). Overall antihypertensive medication use increased bleeding with an odds ratio of 1.24, whereas angiotensin II receptor antagonists had a reduced odds ratio (0.53). Postmenopausal women with hypertension are more likely to bleed than postmenopausal women without hypertension when taking continuous estrogen-progestin, with less bleeding in women using angiotensin II receptor antagonists. This finding is novel and supports our hypothesis that the endometrial renin-angiotensin-aldosterone system may contribute to endometrial bleeding.

The prevalence and incidence of both obesity and disability are projected to increase in the coming decades. The authors examined the relation between obesity and disability in older adults from 6 Latin American cities participating in the Health, Well-Being and Aging in Latin America and the Caribbean (SABE) Study (1999-2000). The sample included 6,166 participants aged 65 years or more. Data on sociodemographic factors, smoking status, medical conditions, body mass index (BMI; weight (kg)/height (m)(2)), and self-reported activities of daily living (ADL) were obtained. The prevalence of obesity (BMI > or = 30) ranged from 13.3% in Havana, Cuba, to 37.6% in Montevideo, Uruguay. Using a BMI of 18.5-<25 as the reference category and controlling for all covariates, the lowest odds ratio for ADL limitation was for a BMI of 25-<30 (odds ratio = 1.10, 95% confidence interval: 0.93, 1.30), and the highest odds ratio for ADL limitation was for a BMI of 35 or higher (odds ratio = 1.63, 95% confidence interval: 1.26, 2.11). The results indicated that obesity is an independent factor contributing to ADL disability in these populations and should be included in future planning to reduce the impact of disability on global health.

Purpose Some studies have reported reduced risks of advanced, but not early, prostate cancer among statin users, and one study found a reduced risk only among statin users who had also used nonsteroidal anti-inflammatory drugs (NSAIDs). We have previously reported no association between statin use and prostate cancer in our hospital-based Case Control Surveillance Study. The purpose of the present analyses was to update the findings by cancer stage and to evaluate the joint use of statins and NSAIDs. Methods Cases were 1367 men with prostate cancer and controls were 2007 men with diagnoses unrelated to statin or NSAID use. We used multivariable logistic regression analyses to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for statin use compared with no use, and joint use of statin and NSAIDs compared with use of neither. Results The odds ratio among regular statin users was 1.1 (95% CI 0.9–1.5), and odds ratios were similar among early and late stage cancers. The odds ratio among joint statin and NSAID users was 1.1 (95% CI 0.7–1.6). Conclusion The present results do not support a protective effect of statin use, or statin and NSAID use, on the risk of advanced prostate cancer. PMID:20582910

The validity of exposure data collected from proxy respondents of myocardial infarction patients has scarcely been studied. We assessed the level of disagreement between myocardial infarction patients and their spouses with respect to the reporting of the patient´s cardiovascular risk exposures. Within the frame of the Stockholm Heart Epidemiology Program (SHEEP), a case-control study of risk factors of myocardial infarction performed in Stockholm county 1992-1994, a subset of 327 first time myocardial infarction cases aged 45-70 who survived >28 days after the event and who co-habited with a spouse or common-law spouse (proxy) were identified between 1993-04-05 and 1993-12-31. Among these, 243 cases participated along with their respective proxy in the present study. Control individuals, matched to cases by age, sex and residential area were also included (n = 243). Data were collected using questionnaires. Using conditional logistic regression we calculated for each of 82 exposures the odds ratio based on information collected from 1) myocardial infarction cases and controls [odds ratio A] and 2) proxies and the same set of controls [odds ratio B]. Disagreement was measured by calculating the ratio between odds ratio B and odds ratio A with 95% confidence intervals (CI) calculated using resampling bootstrap. For the vast majority of the exposures considered including diet, smoking, education, work-related stress, and family history of CVD, there was no statistically significant disagreement between myocardial infarction patients and proxies (n = 243 pairs). However, leisure time physical inactivity (proxy bias = 1.59, 95% CI 1.05-3.57) was overestimated by spouses compared to myocardial infarction patients. A few other exposures including some sleep-related problems and work-related issues also showed disagreement. Myocardial infarction patients and their spouses similarly reported data on a wide range of exposures including the majority of the traditional cardiovascular risk factors, leisure time physical inactivity being an exception.

Knowledge is limited on healthy lifestyle behaviors and their associations with glycemic and blood pressure control among patients with diabetes and hypertension in the United Arab Emirates (UAE). To examine healthy lifestyle behaviors and their associations with glycemic and blood pressure control among patients with hypertension and diabetes, and improvement after the implementation of an intervention in a Chronic Disease Program. All patients with diabetes or hypertension attending seven primary health care centers in Al Ain, UAE during a designated three-week period in July and August 2009. Nurses conducted an audit of patients' adherence to health lifestyle behaviors related to meal planning, smoking, exercise, blood glucose and blood pressure monitoring at home, and foot and eye exams in the Chronic Disease Program clinics after a self-management intervention. A perceived knowledge score and discussion scores (based on the frequency the patients discuss diabetes and hypertension management issues with their providers) were calculated. Data were analyzed using linear regression and odds ratios. Patients reported acceptable rates of adherence to healthy lifestyle behaviors, including a low smoking rate (6% in males), following a meal plan and exercising (88.6% and 78.7%, respectively). Among patients with diabetes, 59% tested their blood glucose levels at least once a week compared to only 15.3% of those with hypertension monitoring their blood pressure levels at home. Only 33% of the participants were following the current physical activity recommendations. Healthy lifestyle behaviors fell into the following clusters: meal planning with exercise (odds ratio (OR): 8.9 [3.3-23.7]), meal planning with foot exams (OR: 10.6 [3.4-32.9]) and exercising and foot exams (OR: 5.2 [1.9-14.2]). This practice-based audit provides an essential assessment for future interventions to improve adherence to healthy life style behaviors among patients with diabetes and hypertension attending primary health clinics in the UAE. © The Author(s) 2014.

The Integrated Knowledge Engine (IKE) is a tool of Bayesian analysis, based on Bayesian Belief Networks or Bayesian networks for short. A Bayesian network is a graphical model (directed acyclic graph) that allows representing the probabilistic structure of many variables assuming a localized type of dependency called the Markov property. The Markov property in this instance makes any node or random variable to be independent of any non-descendant node given information about its parent. A direct consequence of this property is that it is relatively easy to incorporate new evidence and derive the appropriate consequences, which in general is notmore » an easy or feasible task. Typically we use Bayesian networks as predictive models for a small subset of the variables, either the leave nodes or the root nodes. In IKE, since most applications deal with diagnostics, we are interested in predicting the likelihood of the root nodes given new observations on any of the children nodes. The root nodes represent the various possible outcomes of the analysis, and an important problem is to determine when we have gathered enough evidence to lean toward one of these particular outcomes. This document presents criteria to decide when the evidence gathered is sufficient to draw a particular conclusion or decide in favor of a particular outcome by quantifying the uncertainty in the conclusions that are drawn from the data. The material in this document is organized as follows: Section 2 presents briefly a forensics Bayesian network, and we explore evaluating the information provided by new evidence by looking first at the posterior distribution of the nodes of interest, and then at the corresponding posterior odds ratios. Section 3 presents a third alternative: Bayes Factors. In section 4 we finalize by showing the relation between the posterior odds ratios and Bayes factors and showing examples these cases, and in section 5 we conclude by providing clear guidelines of how to use these for the type of Bayesian networks used in IKE.« less

Objective  This retrospective cohort study examined the effect of birth order on neonatal morbidity and mortality in very preterm twins. Study Design  Using 2005 to 2012 data from the Canadian Neonatal Network, very preterm twins born between 24 0/7 and 32 6/7 weeks of gestation were included. Odds of morbidity and mortality of second-born cotwins compared with first-born cotwins were examined by matched-pair analysis. Outcomes were neonatal death, severe brain injury (intraventricular hemorrhage grade 3 or 4 or persistent periventricular echogenicity), bronchopulmonary dysplasia, severe retinopathy of prematurity (ROP) (> stage 2), necrotizing enterocolitis (≥ stage 2), and respiratory distress syndrome (RDS). Multivariable analysis was performed adjusting for confounders. Result  There were 6,636 twins (3,318 pairs) included with a mean gestational age (GA) of 28.9 weeks. A higher rate of small for GA occurred in second-born twins (10 vs. 6%). Mortality was significantly lower for second-born twins (4.3 vs. 5.3%; adjusted odds ratio: 0.75; 95% confidence interval [CI]: 0.59-0.95). RDS (66 vs. 60%; adjusted odds ratio: 1.40; 95% CI: 1.29-1.52) and severe retinopathy (9 vs. 7%; adjusted odds ratio: 1.46; 95% CI: 1.07-2.01) were significantly higher in second-born twins. Conclusion  Thus, while second-born twins had reduced odds of mortality, they also had increased odds of RDS and ROP. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Objective African American young adults are disproportionately affected by the HIV/AIDS epidemic and often unaware of their personal risk for HIV. Historically black colleges and universities (HBCUs) enroll 25% of college-educated African American young adults and can play an important role in HIV prevention. We examined HIV/AIDS knowledge of students at HBCUs to inform and strengthen our HIV prevention efforts at HBCUs. Methods African American undergraduate HBCU students completed online surveys assessing HIV/AIDS knowledge and behaviors, and we analyzed data to assess their knowledge and behaviors. Results A total of 1,051 of 1,230 surveys completed (85.4%) were analyzable. Eighty-two percent of students had average/high HIV knowledge scores. Seventy-nine percent of students surveyed perceived themselves to be at low risk for HIV infection; 64% of those who had at least two or more sex partners had not used a condom at last sex encounter. In the final model, significant independent effects were identified for average/high knowledge of HIV risk, including agreeing with assessing a potential partner's HIV risk by all of the five actions listed (adjusted odds ratio [AOR] = 2.7, 95% confidence interval [CI] 1.7, 4.3) and never using a needle to inject drugs (AOR=5.6, 95% CI 3.2, 9.7). Conclusions Educating students about effectively assessing sex partner risk will improve HIV knowledge and prevention efforts at HBCUs. PMID:21886325

Background: Reproductive health (RH) is a critical component of women’s health and overall well-being around the world, especially in developing countries. We examine the factors that determine knowledge of RH care among female university students in Bangladesh. Methods: Data on 300 female students were collected from Rajshahi University, Bangladesh through a structured questionnaire using purposive sampling technique. The data were used for univariate analysis, to carry out the description of the variables; bivariate analysis was used to examine the associations between the variables; and finally, multivariate analysis (binary logistic regression model) was used to examine and fit the model and interpret the parameter estimates, especially in terms of odds ratios. Results: The results revealed that more than one-third (34.3%) respondents do not have sufficient knowledge of RH care. The χ2-test identified the significant (p < 0.05) associations between respondents’ knowledge of RH care with respondents’ age, education, family type, watching television; and knowledge about pregnancy, family planning, and contraceptive use. Finally, the binary logistic regression model identified respondents’ age, education, family type; and knowledge about family planning, and contraceptive use as the significant (p < 0.05) predictors of RH care. Conclusions and Global Health Implications: Knowledge of RH care among female university students was found unsatisfactory. Government and concerned organizations should promote and strengthen various health education programs to focus on RH care especially for the female university students in Bangladesh. PMID:27622005

As the volume of medical literature increases exponentially, maintaining current clinical practice is becoming more difficult. Multiple, Internet-based journal clubs and alert services have recently emerged. The purpose of this study is to determine whether the use of the e-mail alert service, Nephrology Now, increases knowledge translation regarding current nephrology literature. Nephrology Now is a nonprofit, monthly e-mail alert service that highlights clinically relevant articles in nephrology. In 2007-2008, the authors randomized 1,683 subscribers into two different groups receiving select intervention articles, and then they used an online survey to assess both groups on their familiarity with the articles and their acquisition of knowledge. Of the randomized subscribers, 803 (47.7%) completed surveys, and the two groups had a similar number of responses (401 and 402, respectively). The authors noted no differences in baseline characteristics between the two groups. Familiarity increased as a result of the Nephrology Now alerts (0.23 ± 0.087 units on a familiarity scale; 95% confidence interval [CI]: 0.06-0.41; P = .007) especially in physicians (multivariate odds ratio 1.83; P = .0002). No detectable improvement in knowledge occurred (0.03 ± 0.083 units on a knowledge scale; 95% CI: -0.13 to 0.20; P = .687). An e-mail alert service of new literature improved a component of knowledge translation--familiarity--but not knowledge acquisition in a large, randomized, international population.

With an increase and diversity in ethnic populations in Westernized countries, understanding the differences in levels of knowledge surrounding hypertension is important in planning appropriate prevention strategies. The purpose of our study was to assess levels of hypertension knowledge in Chinese, Indian and White populations in a large metropolitan Canadian city. A telephone survey was conducted in English, Chinese (Cantonese and Mandarin) and Indian languages (Hindi, Punjabi and Urdu). Hypertension knowledge was assessed through a 10-item validated instrument; respondents received 1 point for each correct answer. Logistic regression was used to test differences in hypertension knowledge among these three populations. Survey response rates were 68.7% (301) for Chinese, 61.3% (248) for Indian and 69.7% (254) for White populations. The average hypertension knowledge score for Chinese respondents was 7.23 out of 10, 7.11 for Indian respondents and 7.28 for White respondents. Compared to White respondents, Chinese respondents were less likely than White respondents to know high blood pressure can cause heart attacks (adjusted odds ratio [aOR]: .43, 95% confidence interval [CI]: .19-.96] and Indian respondents were less likely to know losing weight usually decreases blood pressure (aOR: .38, 95% CI: .21-.68). Hypertension knowledge levels among these three ethnic/racial populations were similar and relatively high and varied by content. Low levels of knowledge for Chinese and Indian ethnic populations were on hypertension risk factors, long-term consequences of hypertension and anti-hypertensive medication adherence. Specifically, females, recent immigrants to Canada and Chinese seniors were identified as sub-groups who should be targeted for hypertension knowledge promotion.

To evaluate the association between the type of information source and the level of knowledge about diabetes mellitus in patients with type 2 diabetes. A cross-sectional study was conducted at a reference diabetes and hypertension center in Lima, Peru, during 2014. Level of knowledge was measured using the Diabetes Knowledge Questionnaire-24 and 12 information sources. Patients with 75% correct answers were considered to have a good knowledge. Adjusted odds ratios were calculated. Of the total 464 patients enrolled, 52.2% were females, and 20.3% used the Internet as information source. Mean knowledge was 12.9±4.8, and only 17.0% had a good knowledge, which was associated with information on diabetes obtained from the Internet (OR=2.03, 95% CI 1.32 to 3.14), and also from other patients (OR=1.99, 95% CI 1.20 to 3.31). Good knowledge was also associated with postgraduate education (OR=3.66, 95% CI 1.21 to 11.09), disease duration longer than 12 years (OR=1.91, 95% CI 1,22 to 3.01), and age older than 70 years (OR=0.39, 95% CI 0.21-0.72). Search for information in the Internet was positively associated to a good level of knowledge. It is suggested to teach patients with diabetes to seek information on the Internet and, on the other hand, to develop virtual spaces for interaction of patients with diabetes. Copyright © 2016 SEEN.

Because consistent condom use is an effective strategy in the prevention of sexually transmitted infections and HIV transmission, it is important to examine social cognitive influences of consistent condom use not only among female sex workers (FSWs) but also among their male clients, for whom less is known. Because little is known about how HIV knowledge and condom attitudes affect condom use among male clients of FSWs in the Philippines, the main objective was to determine what characteristics (age, education, HIV knowledge, marital status) as well as attributes taken from protection motivation theory (perceived vulnerability, perceived severity, response efficacy) are significantly associated with consistent condom use among male clients of FSWs. Logistic regression analyses showed that the odds of using condoms consistently with an FSW are 13% higher for those with more years of education (adjusted odds ratio [AOR] = 1.13; 95% confidence interval [CI] = 1.03, 1.23), higher versus lower perception of severity of HIV/AIDS (AOR = 1.97; 95% CI = 1.04, 3.73), and had a higher score for response efficacy of condoms (AOR = 1.14; 95% CI = 1.03, 1.27). Future HIV/AIDS prevention interventions that address condom use among male clients should promote educational attainment and focus on awareness of the enduring negative health consequences of acquiring HIV/AIDS, as well as cultivate positive attitudes toward the efficacy of condom use, using creative social marketing strategies.

To study the prevalence of poorly controlled vitamin K antagonist anticoagulation in Spain in patients with nonvalvular atrial fibrillation, and to identify associated factors. We studied 1056 consecutive patients seen at 120 cardiology clinics in Spain between November 2013 and March 2014. We analyzed the international normalized ratio from the 6 months prior to the patient's visit, calculating the prevalence of poorly controlled anticoagulation, defined as < 65% time in therapeutic range using the Rosendaal method. Mean age was 73.6 years (standard deviation, 9.8 years); women accounted for 42% of patients. The prevalence of poorly controlled anticoagulation was 47.3%. Mean time in therapeutic range was 63.8% (25.9%). The following factors were independently associated with poorly controlled anticoagulation: kidney disease (odds ratio = 1.53; 95% confidence interval, 1.08-2.18; P = .018), routine nonsteroidal anti-inflammatory drugs (odds ratio = 1.79; 95% confidence interval, 1.20-2.79; P = .004), antiplatelet therapy (odds ratio = 2.16; 95% confidence interval, 1.49-3.12; P < .0001) and absence of angiotensin receptor blockers (odds ratio = 1.39; 95% confidence interval, 1.08-1.79; P = .011). There is a high prevalence of poorly controlled vitamin K antagonist anticoagulation in Spain. Factors associated with poor control are kidney disease, routine nonsteroidal anti-inflammatory drugs, antiplatelet use, and absence of angiotensin receptor blockers.

The objective of this cross-sectional study was to determine the factors associated with the attitudes toward premarital sexual activities among school-going adolescents in Kelantan, Malaysia. It was conducted among 1032 secondary school students using a self-administered validated questionnaire. Multiple logistic regression revealed that the risk factors for having permissive attitudes toward practice of premarital sexual activities were male students (odds ratio [OR] = 1.83; 95% confidence interval [CI] = 1.34-2.48), being less religious (OR = 2.02; 95% CI = 1.49-2.73), and younger age group of students (13 to 14 years old; OR = 1.42; 95% CI = 1.05-1.92). Having good knowledge on sexual and reproductive health was a protective factor against permissive sexual attitude (OR = 0.27; 95% CI = 0.20-0.36). In conclusion, male and young adolescents were at risk of having permissive attitudes toward sexual behaviors, but good knowledge on sexual and reproductive health and being more religious may protect them from it. © 2012 APJPH.

2017-01-01

Objective A randomized control pilot study was conducted with Black men who have sex with men (BMSM; N = 42) aged 18–30 years to examine the feasibility of implementing a video intervention delivered using Facebook to motivate HIV testing. Methods At baseline, participants were unaware of their HIV status and had not tested for HIV in the past 6 months, residing in Los Angeles County. The intervention content included topics such as social influence, HIV knowledge, stigma, HIV positive knowledge, and benefits of knowing one’s HIV status. Findings Logistic regression revealed that those receiving the video intervention were 7 times more likely to have tested for HIV than those in the control group at 6-week follow-up (odds ratio [OR] = 7.00, 95% confidence interval [1.72, 28.33], p = .006). Conclusion Data suggest that the intervention was feasible for motivating HIV testing. PMID:29276800

Using a case-control study comprising about 600 men with lung cancer in northern Sweden the potential risk of different occupations and groups of occupations was studied. Longitudinal data concerning occupation, employment, and smoking habits were obtained by questionnaires. Some occupational groups (underground miners, copper smelter workers, electricians, and plumbers) exposed to previously known lung carcinogenic agents such as radon daughters, arsenic, and asbestos, had considerably increased odds ratios, which persisted after adjustment for smoking. A slightly raised odds ratio was observed in a group of blue collar workers potentially exposed to lung carcinogenic agents; this rise in the group as a whole mainly disappeared after adjustment for smoking. Farmers and foresters had strikingly low odds ratios, which could only partly be explained by their more moderate smoking habits. The population aetiological fraction attributable to occupation was estimated as 9%. PMID:3620367

Identify factors associated with obstructive sleep apnea (OSA) risk during commercial driver medical examinations. A case-control study was conducted at an occupational health clinic by reviewing the commercial driver medical examinations medical records performed from January 2007 to December 2008. The magnitude of association with OSA was estimated with logistic regression. Among 1890 commercial motor vehicle drivers, 51 were confirmed positive for OSA by polysomnography after initial screening by Joint Task Force guidelines, yielding estimated positive predictive values of 78.5% for the screening criteria. Multivariable logistic regression showed that body mass index ≥ 30 (odds ratio: 26.86), hypertension (odds ratio: 2.57), and diabetes (odds ratio: 2.03) were independently associated with OSA. Medical examiners' use of objectively measurable risk factors, such as obesity, history of hypertension, and/or diabetes, rather than symptoms, may be more effective in identifying undiagnosed OSA in commercial drivers during the commercial driver medical examinations.

Topiramate is an approved and effective drug in migraine prophylaxis. Paresthesia is the most commonly reported side effect. The primary objective of this study was to compare the frequency of topiramate-induced paresthesia in migraine headache to epileptic patients. Patients with migraine without aura and epilepsy were enrolled in this observational study. All cases were interviewed by telephone about their history of paresthesia. Confounding factors were controlled through logistic regression. The odds ratio of developing topiramate-induced paresthesia in migraine compared to epilepsy patients was 3.4. Three factors were independent contributors to developing topiramate-induced paresthesia: female sex (odds ratio 2.1), topiramate dosage (odds ratio 0.3) and duration of therapy. Our findings indicate an independent association between migraine and development of paresthesia. Migraineurs were more likely than epileptic patients to report paresthesia as topiramate adverse effects. Female sex, treatment duration and topiramate dosage contribute significantly to subsequent development of paresthesia.

To determine whether platelet counts can predict the likelihood of successful closure of patent ductus arteriosus (PDA) with indomethacin. This was a retrospective cohort study of infants <32 weeks' gestational age (GA) and birth weight <1500 g with PDA. Clinical characteristics between infants who achieved ductal closure with indomethacin and those who failed were compared. Multivariable logistic regression was used to identify predictors of successful ductal closure. In infants with hemodynamically significant PDA, older GA (odds ratio=1.54; 95% confidence interval: 1.12 to 2.13), male gender (odds ratio=3.02; 95% confidence interval: 1.08 to 8.49) and higher platelet count (odds ratio=1.5; 95% confidence interval: 1.04 to 2.17) prior to indomethacin treatment were associated with successful ductal closure with indomethacin. Older GA, male gender and higher platelet count at time of treatment of hemodynamically significant PDA are predictors of successful ductal closure with indomethacin.

In women with gestational diabetes mellitus, it is not clear whether routine induction of labor at <40 weeks of gestation is beneficial to mother and newborn infant. The purpose of this study was to compare outcomes among women with gestational diabetes mellitus who had induction of labor at either 38 or 39 weeks with those whose pregnancy was managed expectantly. We included all women in Ontario, Canada, with diagnosed gestational diabetes mellitus who had a singleton hospital birth at ≥38 + 0 weeks of gestation between April 2012 and March 2014. Data were obtained from the Better Outcomes Registry & Network Ontario, which is a province-wide registry of all births in Ontario, Canada. Women who underwent induction of labor at 38 + 0 to 38 + 6 weeks of gestation (38-IOL; n = 1188) were compared with those who remained undelivered until 39 + 0 weeks of gestation (38-Expectant; n = 5229). Separately, those women who underwent induction of labor at 39 + 0 to 39 + 6 weeks of gestation (39-IOL; n = 1036) were compared with women who remained undelivered until 40 + 0 weeks of gestation (39-Expectant; n = 2162). Odds ratios and 95% confidence intervals were adjusted for maternal age, parity, insulin treatment, and prepregnancy body mass index. Of 281,480 women who gave birth during the study period, 14,600 women (5.2%) had gestational diabetes mellitus; of these, 8392 women (57.5%) met all inclusion criteria. Compared with the 38-Expectant group, those women in the 38-IOL group had lower odds for cesarean delivery (adjusted odds ratio, 0.73; 95% confidence interval, 0.52-0.90), higher odds for neonatal intensive care unit admission (adjusted odds ratio, 1.36; 95% confidence interval, 1.09-1.69), and no difference in other maternal-newborn infant outcomes. Compared with the 39-Expectant group, women in the 39-IOL group likewise had lower odds for cesarean delivery (adjusted odds ratio, 0.73; 95% confidence interval, 0.58-0.93) but no difference in neonatal intensive care unit admission (adjusted odds ratio, 0.83; 95% confidence interval, 0.61-1.11). In women with gestational diabetes mellitus, the routine induction of labor at 38 or 39 weeks is associated with a lower risk of cesarean delivery compared with expectant management but may increase the risk of neonatal intensive care unit admission when done at <39 weeks of gestation.

Symptoms of urinary incontinence are commonly perceived to vary over time; yet, there is limited quantitative evidence regarding the natural history of urinary incontinence, especially over the long term. We sought to delineate the course of urinary incontinence symptoms over time, using 2 large cohorts of middle-aged and older women, with data collected over 10 years. We studied 9376 women from the Nurses' Health Study, age 56-81 years at baseline, and 7491 women from the Nurses' Health Study II, age 39-56 years, with incident urinary incontinence in 2002 through 2003. Urinary incontinence severity was measured by the Sandvik severity index. We tracked persistence, progression, remission, and improvement of symptoms over 10 years. We also examined risk factors for urinary incontinence progression using logistic regression models. Among women age 39-56 years, 39% had slight, 45% had moderate, and 17% had severe urinary incontinence at onset. Among women age 56-81 years, 34% had slight, 45% had moderate, and 21% had severe urinary incontinence at onset. Across ages, most women reported persistence or progression of symptoms over follow-up; few (3-11%) reported remission. However, younger women and women with less severe urinary incontinence at onset were more likely to report remission or improvement of symptoms. We found that increasing age was associated with higher odds of progression only among older women (age 75-81 vs 56-60 years; odds ratio, 1.84; 95% confidence interval, 1.51-2.25). Among all women, higher body mass index was strongly associated with progression (younger women: odds ratio, 2.37; 95% confidence interval, 2.00-2.81; body mass index ≥30 vs <25 kg/m 2 ; older women: odds ratio, 1.93; 95% confidence interval, 1.62-2.22). Additionally, greater physical activity was associated with lower odds of progression to severe urinary incontinence (younger women: odds ratio, 0.86; 95% confidence interval, 0.71-1.03; highest vs lowest quartile of activity; older women: odds ratio, 0.68; 95% confidence interval, 0.59-0.80). Most women with incident urinary incontinence continued to experience symptoms over 10 years; few had complete remission. Identification of risk factors for urinary incontinence progression, such as body mass index and physical activity, could be important for reducing symptoms over time. Copyright © 2018 Elsevier Inc.

Objective To use the rs1229984 variant in the alcohol dehydrogenase 1B gene (ADH1B) as an instrument to investigate the causal role of alcohol in cardiovascular disease. Design Mendelian randomisation meta-analysis of 56 epidemiological studies. Participants 261 991 individuals of European descent, including 20 259 coronary heart disease cases and 10 164 stroke events. Data were available on ADH1B rs1229984 variant, alcohol phenotypes, and cardiovascular biomarkers. Main outcome measures Odds ratio for coronary heart disease and stroke associated with the ADH1B variant in all individuals and by categories of alcohol consumption. Results Carriers of the A-allele of ADH1B rs1229984 consumed 17.2% fewer units of alcohol per week (95% confidence interval 15.6% to 18.9%), had a lower prevalence of binge drinking (odds ratio 0.78 (95% CI 0.73 to 0.84)), and had higher abstention (odds ratio 1.27 (1.21 to 1.34)) than non-carriers. Rs1229984 A-allele carriers had lower systolic blood pressure (−0.88 (−1.19 to −0.56) mm Hg), interleukin-6 levels (−5.2% (−7.8 to −2.4%)), waist circumference (−0.3 (−0.6 to −0.1) cm), and body mass index (−0.17 (−0.24 to −0.10) kg/m2). Rs1229984 A-allele carriers had lower odds of coronary heart disease (odds ratio 0.90 (0.84 to 0.96)). The protective association of the ADH1B rs1229984 A-allele variant remained the same across all categories of alcohol consumption (P=0.83 for heterogeneity). Although no association of rs1229984 was identified with the combined subtypes of stroke, carriers of the A-allele had lower odds of ischaemic stroke (odds ratio 0.83 (0.72 to 0.95)). Conclusions Individuals with a genetic variant associated with non-drinking and lower alcohol consumption had a more favourable cardiovascular profile and a reduced risk of coronary heart disease than those without the genetic variant. This suggests that reduction of alcohol consumption, even for light to moderate drinkers, is beneficial for cardiovascular health. PMID:25011450

Some studies have reported that vascular endothelial growth factor (VEGF) genetic polymorphisms are associated with recurrent pregnancy loss (RPL), but the results are controversial. This study is aimed to quantify the strength of this association. A systematic review of the published literature from Medline, Springer, and China National Knowledge Infra structure (CNKI) databases was conducted and investigations of VEGF genetic polymorphisms in RPL were selected. We estimated the pooled odds ratio (OR) to assess this possible association. Fifteen case-control studies comprising 2702 cases and 2667 controls and including five genetic polymorphisms (rs3025039, rs833061, rs15703060, rs2010963 and rs699947) were eligible for this meta-analysis. The overall analysis suggested that only two genetic polymorphisms (rs1570360, rs3025039) were associated with increased risk of RPL. A significant increased risk between VEGF rs1570360 polymorphism and RPL was only found under the dominant model in Caucasians (OR=1.70, 95% CI 1.02-2.82, P=0.04). Whereas, we found that VEGF rs3025039 polymorphism was significantly associated with RPL both under the dominant and recessive model in East Asians, and their summary odd ratios and 95% CIs were 1.26, 1.04-1.53, P=0.02 and 2.94, 1.80-4.83, P=0, respectively. This meta-analysis showed that only rs1570360 (especially in Caucasians) and rs3025039 (especially in East Asians) may be risk factors for RPL. Copyright © 2017 Elsevier B.V. All rights reserved.

It is important to control blood pressure as well as to control blood glucose for the prevention of diabetic nephropathy. However, to our knowledge, there are no reports investigating which blood pressure, including morning, evening and clinic, is more closely associated with albuminuria and whether one measurement is sufficient or not in patients with Type 2 diabetes. We measured morning, evening and clinic blood pressure and compared the area under the curve (AUC) of blood pressure for urinary albumin excretion equal to or more than 30 mg/g creatinine using receiver-operating characteristic curve analyses and odds ratio for albuminuria defined as urinary albumin excretion equal to or more than 30 mg/g creatinine in 858 patients with Type 2 diabetes. Odds ratio (95% confidence interval (CI)) of morning, evening and clinic systolic blood pressure for albuminuria was 1.034 (1.024 - 1.044), 1.033 (1.023 - 1.043) and 1.013 (1.055 - 1.021), respectively (p < 0.001 in all), and AUC of morning, evening and clinic systolic blood pressure was 0.644 (0.628 - 0.700) (p < 0.001 vs. clinic), 0.660 (0.623 - 0.696) (p < 0.001 vs. clinic) and 0.597 (0.559 - 0.636), respectively. AUC of the second morning systolic blood pressure was greater than the first (p = 0.033). The second measurement of morning systolic blood pressure is more closely associated with albuminuria than the first measurement of the morning in addition to clinic systolic blood pressure.

Most studies on euthanasia fail to explain the intentions of health professionals when faced with performing euthanasia and are atheoretical. The purpose of this study was to identify the psychosocial determinants of nurses' intention to practise euthanasia in palliative care if it were legalised. A cross-sectional study using a validated anonymous questionnaire based on an extended version of the Theory of Planned Behaviour. A random sample of 445 nurses from the province of Quebec, Canada, was selected for participation in the study. The study was reviewed and approved by the Ethics Committee of the Centre hospitalier universitaire de Québec. The response rate was 44.2% and the mean score for intention was 4.61 ± 1.90 (range: 1-7). The determinants of intention were the subjective (odds ratio = 3.08; 95% confidence interval: 1.50-6.35) and moral (odds ratio = 2.95; 95% confidence interval: 1.58-5.49) norms. Specific beliefs which could discriminate nurses according to their level of intention were identified. Overall, nurses have a slightly positive intention to practise euthanasia. Their family approval seems particularly important and also the approval of their medical colleagues. Nurses' moral norm was related to beneficence, an ethical principle. To our knowledge, this is the first study to identify nurses' motivations to practise euthanasia in palliative care using a validated psychosocial theory. It also has the distinction of identifying the ethical principles underlying nurses' moral norm and intention. © The Author(s) 2014.

The role of occupational hazards in occupational injury may be mediated by individual factors across various age groups. This study assessed the role of occupational hazards as well as contribution of individual factors to injuries among Indian and French coalminers. We conducted a case-control study on 245 injured workers and on 330 controls without any injuries from Indian coal mines using face-to-face interviews, and a retrospective study on 516 French coalminers using a self-administered questionnaire including potential occupational and personal factors. Data were analyzed using logistic models. The annual rate of injuries was 5.5% for Indian coalminers and 14.9% for the French ones. Logistic model including all occupational factors showed that major injury causes were: hand-tools, material handling, machines, and environment/work-geological/strata conditions among Indian miners (adjusted odds-ratios 2.01 to 3.30) and biomechanical exposure score among French miners (adjusted odds-ratio 3.01 for score the 1-4, 3.47 for the score 5-7, and 7.26 for score ≥ 8, vs. score 0). Personal factors among Indian and French coalminers reduced/exacerbated the roles of various occupational hazards to a different extent depending on workers' age. We conclude that injury roles of occupational hazards were reduced or exacerbated by personal factors depending on workers' age in both populations. This knowledge is useful when designing prevention which should definitely consider workers' age.

Poor Medicare knowledge is associated with worse health outcomes, especially in low-income patients. We examined the association of health literacy and cognition with actual and perceived Medicare knowledge in a sample of inner-city older adults. We conducted a cross-sectional analysis of data on 336 adults ages 65 years and older with Medicare coverage recruited from senior centers and low-income housing facilities in Manhattan, New York. Actual Medicare knowledge was determined by a summary score of 9 true/false questions about the Medicare program and perceived Medicare knowledge with a single item. Validated measures were used to assess health literacy and general cognition. Among respondents, 63.1% had high actual Medicare knowledge, and 36.0% believed that they knew what they needed to know about Medicare. Actual and perceived Medicare knowledge were poorly correlated (r = -.01, p > .05). In multivariable models, low health literacy was significantly associated with actual Medicare knowledge (β = -8.30, SE = 2.71, p < .01) but not perceived Medicare knowledge (β = 0.37, SE = 0.22, p = .09). Individuals with low health literacy were more likely to perceive their Medicare knowledge as adequate when actual Medicare knowledge was low (adjusted odds ratio = 3.30, 95% confidence interval [1.20, 9.05], p < .05). These results show that older adults with low health literacy are more likely to have poor understanding of the Medicare program and yet more likely to believe that their understanding of the program is adequate. This combination of factors may place them at increased risk for poor access to information about the Medicare program and diminish their ability to make fully informed choices.

Research links sex ratios with the likelihood of marriage and divorce. However, whether sex ratios similarly influence precursors to marriage—transitions in and out of dating or cohabiting relationships—is unknown. Utilizing data from the Toledo Adolescent Relationships Study (TARS) and the 2000 census, this study assesses whether sex ratios influence the formation and stability of emerging adults’ romantic relationships. Findings show that relationship formation is unaffected by partner availability, yet the presence of partners increases women’s odds of cohabiting, decreases men’s odds of cohabiting, and increases number of dating partners and cheating among men. It appears that sex ratios influence not only transitions in and out of marriage, but also the process through which individuals search for and evaluate partners prior to marriage. PMID:24265510

To establish a baseline for physicians' knowledge of and counseling practices on the use of antibiotics and antimicrobial resistance (AMR), and to determine potential changes in these measures after the implementation of a national AMR awareness campaign. Cross-sectional design. Canada. A total of 1600 physicians. Physicians' knowledge of and counseling practices on antibiotic use and AMR at baseline and after implementation of the AMR awareness campaign. A total of 336 physicians responded to the first-cycle survey (before the campaign), and 351 physicians responded to the second-cycle survey (after the campaign). Overall, physicians' knowledge of appropriate antibiotic use and AMR was high and their counseling practices in relation to antibiotics were appropriate in both surveys. Counseling levels about topics related to infection prevention and control (eg, food handling, household hygiene) were slightly lower. Counseling levels were also lower for certain antibiotic-use practices (eg, proper disposal of antibiotics). In addition, physicians with less than 10 years of practice experience had significantly lower odds of counseling their patients on topics related to preventing antibiotic resistance and infection prevention than those with 15 or more years of practice experience (adjusted odds ratio = 0.27, 95% CI 0.10 to 0.74). Significantly more physicians from the second-cycle survey counseled patients on the appropriate disposal of antibiotics ( P = .03), as well as on some of the infection prevention topics (eg, using antibacterial hand soap [ P = .02] and cleaning supplies [ P = .01]). Most respondents in both surveys reported feeling confident with respect to counseling their patients on the appropriate use of antibiotics and AMR. Physicians' knowledge of and levels of counseling on the use of antibiotics and AMR were high and fairly stable in both survey results. This shows that Canadian physicians are demonstrating behaviour patterns of AMR stewardship. Existing gaps in counseling practices might be a result of physicians believing that pharmacists or nurses are addressing these issues with patients. Future national surveys conducted among pharmacists and nurses would contribute to the evidence base for AMR stewardship activities. Copyright© the College of Family Physicians of Canada.

Lassa fever had been reported as a cause of death especially in endemic parts of Nigeria. This study assessed the knowledge, attitude, and practices toward Lassa fever control and prevention among residents of Ile-Ife, southwest Nigeria. Descriptive cross-sectional study was conducted among consenting randomly selected adults using an interviewer administered questionnaire. Data were analyzed using descriptive and inferential statistics. A total of 400 questionnaires with completed data were analyzed (response rate 96%). Majority, 207 (51.8%), were males while 193 (48.2%) were females. Most, 234 (58.5%), had tertiary education while 148 (37%) had secondary education. Fifty-nine percent had heard of Lassa fever with radio as their major source of information. About 76% had inadequate knowledge, 54% had negative attitude while 51% had poor practice toward Lassa fever. Determinants of knowledge of Lassa fever include having higher education (Adjusted Odd Ratio (AOR) = 11.49, 95% CI [3.10, 42.69], p = .0001), being in civil service (AOR = 0.22, 95% CI [0.09, 0.51], p = .01), and earning higher income (AOR = 4.23, 95% CI [2.61, 6.84], p = .0001). In conclusion, the knowledge, attitude, as well as preventive practices to Lassa fever were poor. It is necessary to increase public education and improve hygienic practices.

The environment in salons provides hairdressers the opportunity to discuss sexual exploits which may promote unhealthy sexual behaviour and increase the risk of sexually transmitted infections (STIs). The aim of the study was to determine sexual practices and knowledge and experience of STIs among hairdressers. The study was carried out in Ibadan, Southwest Nigeria. A total of 1700 hairdressers were selected by cluster sampling technique. Predictors of risky sexual behaviour, knowledge and experience of STIs were identified. Their mean age was 27.0 ± 8.1 years, 860 (50.6%) were single. Majority of them, 1453(85.5%) had ever had sex. The mean age at sexual debut was 15.9 years. Mean knowledge score of STIs was 14.0 out of 25. Only 158(9.3%) experienced symptoms of STIs in the last 12 months. Among singles, senior secondary education was a predictor of ever had sex (odds ratio [OR]: 2.20, 95% confidence interval [CI]: 1.53-3.13), good knowledge of STIs (OR: 2.04, 95% CI: 1.45-2.83) and experience of STIs in the last 12 months (OR: 2.20, 95% CI: 1.53-3.13). Hairdressers, especially singles, are a vulnerable group at risk of reproductive health morbidities. There is a need to focus reproductive health interventions on this occupational group.

Background In Kenya, HIV incidence and prevalence have declined. HIV rates are lower in rural areas than in urban areas. However, HIV infection is reported higher in men in rural areas (4.5%) compared to those in urban areas (3.7%). Objectives This study examined HIV knowledge, feelings, and interactions towards HIV-infected from 302 participants in rural Central Kenya. Methods Chi square tests and multivariable logistic regression analyzed variables of interest. Results Most participants exhibited positive feelings in their interaction with people living with HIV and AIDS (PLWHA). Association between HIV knowledge and socio-demographic characteristics revealed that the proportion of participants with a correct response differed by gender, age, level of education, and marital status ( p < 0.05). Compared to those with inadequate knowledge of HIV/AIDS, participants with adequate HIV/AIDS knowledge were nearly three times as likely to disagree that PLWHA should be legally separated from others to protect public health (adjusted odds ratio: aOR (95% CI) (2.76 (1.12, 6.80). Conclusions HIV stigma continues to impact HIV prevention strategies particularly in rural Central Kenya. Culturally, appropriate interventions addressing HIV knowledge among those with lower levels of education, single, older, and male are warranted. Review of HIV policies separating high-risk populations from the general population is needed to reduce stigma.

OBJECTIVES: This analysis tested the relation between dieting frequency and risk of smoking initiation in a longitudinal sample of adolescents. METHODS: From 1995 to 1997, 1295 middle school girls and boys participated in a nutrition and physical activity intervention study. The prospective association between dieting frequency at baseline and smoking initiation 2 years later was tested. RESULTS: Compared with girls who reported no dieting at baseline, girls who dieted up to once per week had 2 times the adjusted odds of becoming smokers (odds ratio = 2.0; 95% confidence interval = 1.1, 3.5), and girls who dieted more often had 4 times the adjusted odds of becoming smokers (odds ratio = 3.9; 95% confidence interval = 1.5, 10.4). CONCLUSIONS: Dieting among girls may exacerbate risk of initiating smoking, with increasing risk with greater dieting frequency. PMID:11236412

The aim of this study was to examine the pattern of comorbidity among obsessive-compulsive personality disorder (OCPD) and other personality disorders (PDs) in a sample of 400 psychiatric inpatients. PDs were assessed using the Semistructured Clinical Interview for DSM-III-R Personality Disorders (SCID-II). Odds ratios (ORs) were calculated to determine significant comorbidity among OCPD and other axis II disorders. The most elevated odds ratios were found for the cooccurrence of OCPD with cluster A PDs (the "odd" PDs, or paranoid and schizoid PDs). These results are consistent with those of previous studies showing a higher cooccurrence of OCPD with cluster A than with cluster C ("anxious") PDs. In light of these observations, issues associated with the nosologic status of OCPD within the Diagnostic and Statistical Manual of Mental Disorders clustering system remain unsettled.

Self-reported chemicals exposure, beliefs about disease causation, and risk of breast cancer in the Cape Cod Breast Cancer and Environment Study: a case-control study

PubMed Central

2010-01-01

Background Household cleaning and pesticide products may contribute to breast cancer because many contain endocrine disrupting chemicals or mammary gland carcinogens. This population-based case-control study investigated whether use of household cleaners and pesticides increases breast cancer risk. Methods Participants were 787 Cape Cod, Massachusetts, women diagnosed with breast cancer between 1988 and 1995 and 721 controls. Telephone interviews asked about product use, beliefs about breast cancer etiology, and established and suspected breast cancer risk factors. To evaluate potential recall bias, we stratified product-use odds ratios by beliefs about whether chemicals and pollutants contribute to breast cancer; we compared these results with odds ratios for family history (which are less subject to recall bias) stratified by beliefs about heredity. Results Breast cancer risk increased two-fold in the highest compared with lowest quartile of self-reported combined cleaning product use (Adjusted OR = 2.1, 95% CI: 1.4, 3.3) and combined air freshener use (Adjusted OR = 1.9, 95% CI: 1.2, 3.0). Little association was observed with pesticide use. In stratified analyses, cleaning products odds ratios were more elevated among participants who believed pollutants contribute "a lot" to breast cancer and moved towards the null among the other participants. In comparison, the odds ratio for breast cancer and family history was markedly higher among women who believed that heredity contributes "a lot" (OR = 2.6, 95% CI: 1.9, 3.6) and not elevated among others (OR = 0.7, 95% CI: 0.5, 1.1). Conclusions Results of this study suggest that cleaning product use contributes to increased breast cancer risk. However, results also highlight the difficulty of distinguishing in retrospective self-report studies between valid associations and the influence of recall bias. Recall bias may influence higher odds ratios for product use among participants who believed that chemicals and pollutants contribute to breast cancer. Alternatively, the influence of experience on beliefs is another explanation, illustrated by the protective odds ratio for family history among women who do not believe heredity contributes "a lot." Because exposure to chemicals from household cleaning products is a biologically plausible cause of breast cancer and avoidable, associations reported here should be further examined prospectively.

In this study, we performed exome-wide association studies (EWASs) to identify genetic variants that confer susceptibility to ischemic stroke, intracerebral hemorrhage (ICH), or subarachnoid hemorrhage (SAH). EWAS for ischemic stroke was performed using 1,575 patients with this condition and 9,210 controls, and EWASs for ICH and SAH were performed using 673 patients with ICH, 265 patients with SAH and 9,158 controls. Analyses were performed with Illumina HumanExome-12 DNA Analysis BeadChip or Infinium Exome-24 BeadChip arrays. The relation of allele frequencies for 41,339 or 41,332 single nucleotide polymorphisms (SNPs) that passed quality control to ischemic or hemorrhagic stroke, respectively, was examined with Fisher's exact test. Based on Bonferroni's correction, a P-value of <1.21×10−6 was considered statistically significant. EWAS for ischemic stroke revealed that 77 SNPs were significantly associated with this condition. Multivariable logistic regression analysis with adjustment for age, sex and the prevalence of hypertension and diabetes mellitus revealed that 4 of these SNPs [rs3212335 of GABRB3 (P=0.0036; odds ratio, 1.29), rs147783135 of TMPRSS7 (P=0.0024; odds ratio, 0.37), rs2292661 of PDIA5 (P=0.0054; odds ratio, 0.35) and rs191885206 of CYP4F12 (P=0.0082; odds ratio, 2.60)] were related (P<0.01) to ischemic stroke. EWASs for ICH or SAH revealed that 48 and 12 SNPs, respectively, were significantly associated with these conditions. Multivariable logistic regression analysis with adjustment for age, sex and the prevalence of hypertension revealed that rs138533962 of STYK1 (P<1.0×10−23; odds ratio, 111.3) was significantly (P<2.60×10−4) associated with ICH and that rs117564807 of COL17A1 (P=0.0009; odds ratio, 2.23×10−8) was significantly (P<0.0010) associated with SAH. GABRB3, TMPRSS7, PDIA5 and CYP4F12 may thus be novel susceptibility loci for ischemic stroke, whereas STYK1 and COL17A1 may be such loci for ICH and SAH, respectively. PMID:28487959

Predicting the occurrence of embolic events: an analysis of 1456 episodes of infective endocarditis from the Italian Study on Endocarditis (SEI)

PubMed Central

2014-01-01

Background Embolic events are a major cause of morbidity and mortality in patients with infective endocarditis. We analyzed the database of the prospective cohort study SEI in order to identify factors associated with the occurrence of embolic events and to develop a scoring system for the assessment of the risk of embolism. Methods We retrospectively analyzed 1456 episodes of infective endocarditis from the multicenter study SEI. Predictors of embolism were identified. Risk factors identified at multivariate analysis as predictive of embolism in left-sided endocarditis, were used for the development of a risk score: 1 point was assigned to each risk factor (total risk score range: minimum 0 points; maximum 2 points). Three categories were defined by the score: low (0 points), intermediate (1 point), or high risk (2 points); the probability of embolic events per risk category was calculated for each day on treatment (day 0 through day 30). Results There were 499 episodes of infective endocarditis (34%) that were complicated by ≥ 1 embolic event. Most embolic events occurred early in the clinical course (first week of therapy: 15.5 episodes per 1000 patient days; second week: 3.7 episodes per 1000 patient days). In the total cohort, the factors associated with the occurrence of embolism at multivariate analysis were prosthetic valve localization (odds ratio, 1.84), right-sided endocarditis (odds ratio, 3.93), Staphylococcus aureus etiology (odds ratio, 2.23) and vegetation size ≥ 13 mm (odds ratio, 1.86). In left-sided endocarditis, Staphylococcus aureus etiology (odds ratio, 2.1) and vegetation size ≥ 13 mm (odds ratio, 2.1) were independently associated with embolic events; the 30-day cumulative incidence of embolism varied with risk score category (low risk, 12%; intermediate risk, 25%; high risk, 38%; p < 0.001). Conclusions Staphylococcus aureus etiology and vegetation size are associated with an increased risk of embolism. In left-sided endocarditis, a simple scoring system, which combines etiology and vegetation size with time on antimicrobials, might contribute to a better assessment of the risk of embolism, and to a more individualized analysis of indications and contraindications for early surgery.

BACKGROUND The effects of clinical-trial funding on the interpretation of trial results are poorly understood. We examined how such support affects physicians’ reactions to trials with a high, medium, or low level of methodologic rigor. METHODS We presented 503 board-certified internists with abstracts that we designed describing clinical trials of three hypothetical drugs. The trials had high, medium, or low methodologic rigor, and each report included one of three support disclosures: funding from a pharmaceutical company, NIH funding, or none. For both factors studied (rigor and funding), one of the three possible variations was randomly selected for inclusion in the abstracts. Follow-up questions assessed the physicians’ impressions of the trials’ rigor, their confidence in the results, and their willingness to prescribe the drugs. RESULTS The 269 respondents (53.5% response rate) perceived the level of study rigor accurately. Physicians reported that they would be less willing to prescribe drugs tested in low-rigor trials than those tested in medium-rigor trials (odds ratio, 0.64; 95% confidence interval [CI], 0.46 to 0.89; P = 0.008) and would be more willing to prescribe drugs tested in high-rigor trials than those tested in medium-rigor trials (odds ratio, 3.07; 95% CI, 2.18 to 4.32; P<0.001). Disclosure of industry funding, as compared with no disclosure of funding, led physicians to downgrade the rigor of a trial (odds ratio, 0.63; 95% CI, 0.46 to 0.87; P = 0.006), their confidence in the results (odds ratio, 0.71; 95% CI, 0.51 to 0.98; P = 0.04), and their willingness to prescribe the hypothetical drugs (odds ratio, 0.68; 95% CI, 0.49 to 0.94; P = 0.02). Physicians were half as willing to prescribe drugs studied in industry-funded trials as they were to prescribe drugs studied in NIH-funded trials (odds ratio, 0.52; 95% CI, 0.37 to 0.71; P<0.001). These effects were consistent across all levels of methodologic rigor. CONCLUSIONS Physicians discriminate among trials of varying degrees of rigor, but industry sponsorship negatively influences their perception of methodologic quality and reduces their willingness to believe and act on trial findings, independently of the trial’s quality. These effects may influence the translation of clinical research into practice. PMID:22992075

To investigate the distribution and risk factors associated with undiagnosed obstructive sleep apnoea among hypertensive patients. Obstructive sleep Apnoea has been deemed a cardinal risk factor affecting cardiovascular event, and the condition is still frequently overlooked clinically. The lack of advanced diagnosis often causes hypertensive patients with obstructive sleep apnoea to miss opportunities for preventing chronic diseases. A cross-sectional design. A total of 215 hypertensive participants were recruited from the cardiovascular outpatients of medical centre in northern and middle Taiwan. The Chinese version of Pittsburgh Sleep Quality Index, the Chinese version of the Epworth Sleep Scale and a portable sleep monitoring device were used for data collection. Logistic regression analysis was conducted to identify the factors affecting hypertensive patients with obstructive sleep apnoea, and a multinomial logistic regression analysis was used to examine the major influence factors for each obstructive sleep apnoea severity level. 81.9% of the hypertensive participants were found having obstructive sleep apnoea. Concerning to the obstructive sleep apnoea severity, 50.0% of participants had mild obstructive sleep apnoea. After controlling the confounding variables, the supine position (odds ratio, 1.04; 95% CI, 1.01-1.07), SO 2 (odds ratio, 0.58; 95% CI, 0.38-0.89) and oxygen desaturation index (odds ratio, 2.70; 95% CI, 1.18-6.18) were significantly associated with obstructive sleep apnoea. Furthermore, severe obstructive sleep apnoea was significantly correlated with gender (odds ratio, 0.04; 95% CI, 0.00-0.66), excessive daytime sleepiness (odds ratio, 20.27; 95% CI, 1.58-26.97) and oxygen desaturation index (odds ratio, 4.05; 95% CI, 1.86-8.81). Nearly 82% of the hypertensive participants were found having undiagnosed obstructive sleep apnoea, and 80% of them were mild or moderate severity. Oxygen desaturation index, SO 2 and the supine position were found to be major predictors for obstructive sleep apnoea. Remarkably, oxygen desaturation index was the most significant predictor for mild, moderate and severe obstructive sleep apnoea. Healthcare providers should enhance their sensitivities to hypertensive patients at a high risk for obstructive sleep apnoea by actively assessing common obstructive sleep apnoea symptoms and providing strategies to alleviate obstructive sleep apnoea symptoms. © 2018 John Wiley & Sons Ltd.

This study was intended to describe and correlate the neuroimaging findings in pediatric patients after sepsis. Retrospective chart review. Single tertiary care PICU. Patients admitted to Cincinnati Children's Hospital Medical Center with a discharge diagnosis of sepsis or septic shock between 2004 and 2013 were crossmatched with patients who underwent neuroimaging during the same time period. All neuroimaging studies that occurred during or subsequent to a septic event were reviewed, and all new imaging findings were recorded and classified. As many patients experienced multiple septic events and/or had multiple neuroimaging studies after sepsis, our statistical analysis utilized the most recent or "final" imaging study available for each patient so that only brain imaging findings that persisted were included. A total of 389 children with sepsis and 1,705 concurrent or subsequent neuroimaging studies were included in the study. Median age at first septic event was 3.4 years (interquartile range, 0.7-11.5). Median time from first sepsis event to final neuroimaging was 157 days (interquartile range, 10-1,054). The most common indications for final imaging were follow-up (21%), altered mental status (18%), and fever/concern for infection (15%). Sixty-three percentage (n = 243) of final imaging studies demonstrated abnormal findings, the most common of which were volume loss (39%) and MRI signal and/or CT attenuation abnormalities (21%). On multivariable logistic regression, highest Pediatric Risk of Mortality score and presence of oncologic diagnosis/organ transplantation were independently associated with any abnormal final neuroimaging study findings (odds ratio, 1.032; p = 0.048 and odds ratio, 1.632; p = 0.041), although early timing of neuroimaging demonstrated a negative association (odds ratio, 0.606; p = 0.039). The most common abnormal finding of volume loss was independently associated with highest Pediatric Risk of Mortality score (odds ratio, 1.037; p = 0.016) and oncologic diagnosis/organ transplantation (odds ratio, 2.207; p = 0.001) and was negatively associated with early timing of neuroimaging (odds ratio, 0.575; p = 0.037). The majority of pediatric patients with sepsis and concurrent or subsequent neuroimaging have abnormal neuroimaging findings. The implications of this high incidence for long-term neurologic outcomes and follow-up require further exploration.

Wetlands are a source of water out of which humans derive their livelihoods in Sub-Saharan Africa. They are often over-utilized and expose humans to disease-causing infectious agents. This calls for an evaluation of the role of water, sanitation and hygiene (WASH) and their effects in disease prevention and transmission in wetlands. A health risk assessment based on syndromic surveillance of self-reported abdominal complaints and fever gathered from a rural wetland in semiarid Kenya is presented with symptoms serving as proxies for real health threats in wetlands. The incidence of abdominal complaints was significantly higher for those using unimproved water sources compared to improved water users (odds ratio 7.5; 95% CI 2.59-26.9; p=0.001). Drainage of stagnant water near the house (odds ratio 0.2; 95% CI 0.08-0.54; p=0.002) and sanitary hygiene (odds ratio 0.4; 95% CI 0.71-0.97; p=0.056) were associated with reduced risk of abdominal complaints. Drainage of water was also associated with reduced risk of fever (odds ratio 0.3; 95% CI 0.02-0.59; p=0.002) and so was the use of mosquito nets (odds ratio 0.6; 95% CI 0.39-0.02; p=0.063). Usage of wetlands in the afternoon, e.g. for irrigated agriculture, increased the incidence of fever (odds ratio 1.5; 95% CI 0.91-2.33; p=0.040). Overall, there appears a greater likelihood of reducing pathogen exposure in the domestic than in the occupational domain or in the proximity to the wetland. We show that WASH, environmental hygiene and human behaviour are risk factors associated with the contraction of diseases characterized by abdominal complaints (e.g. diarrhoea) and fever (e.g. malaria) in wetlands. The same factors also have the potential to promote human health in the context of wetlands. We demonstrate the applicability of syndromic approaches in surveillance-scarce areas and emphasize the importance of adopting an integrated health-based wetland management that considers WASH and incorporates strategies based on grassroots level risk assessments.

To compare vulvovaginal swabs with endocervical swabs as optimal diagnostic sample for detection of Chlamydia trachomatis infection. A diagnostic test study. An urban sexual health centre. 3973 women aged ≥ 16 years requesting testing for sexually transmitted infections. Participants took a vulvovaginal swab before routine examination, and clinicians took an endocervical swab during examination. Diagnosis of chlamydia infection with samples analysed using the Aptima Combo-2 assay; positive results confirmed with the Aptima CT assay. Of the 3973 participants, 410 (10.3%) were infected with C trachomatis. Infected women were significantly younger (22 v 25 years, P<0.0001) and more likely to have symptoms suggestive of a bacterial sexually transmitted infection (53% v 41%, odds ratio 1.63 (95% CI 1.30 to 2.04)), be a contact of someone with a sexually transmitted infection (25% v 5%, odds ratio 6.18 (4.61 to 8.30)), clinically diagnosed with cervicitis (17% v 4%, odds ratio 4.92 (3.50 to 6.91)), and have pelvic inflammatory disease (9% v 3%, odds ratio 2.85 (1.87 to 4.33)). When women co-infected with gonorrhoea were included in the analysis, there was an association with mixed ethnicity (10% v 7%, odds ratio 1.53 (1.07 to 2.17)); but when those with gonorrhoea were removed, women of white ethnicity were significantly more likely to have chlamydia (85% v 80%, odds ratio 1.40 (1.03 to 1.91)). On analysis of complete paired results, vulvovaginal swabs were significantly more sensitive than endocervical swabs (97% (95% CI 95% to 98%) v 88% (85% to 91%), P<0.00001); corresponding specificities were 99.9% and 100%. In women with symptoms suggestive of a bacterial sexually transmitted infection, vulvovaginal swabs were significantly more sensitive than endocervical swabs (97% (93% to 98%) v 88% (83% to 92%), P=0.0008), as they were in women without symptoms (97% (94% to 99%) v 89% (84% to 93%), P=0.002). Vulvovaginal swabs are significantly better than endocervical swabs at detecting chlamydia in women with and without symptoms suggestive of sexually transmitted infections. In those with symptoms, using endocervical samples rather than vulvovaginal swabs would have missed 9% of infections, or 1 in every 11 cases of chlamydia. ISRCTN42867448.

Associations between reporting of cancer alarm symptoms and socioeconomic and demographic determinants: a population-based, cross-sectional study

PubMed Central

2012-01-01

Background Reporting of symptoms which may signal cancer is the first step in the diagnostic pathway of cancer diseases. Cancer alarm symptoms are common in the general population. Public awareness and knowledge of cancer symptoms are sparse, however, and many people do not seek medical help when having possible cancer symptoms. As social inequality is associated with cancer knowledge, cancer awareness, and information-seeking, our hypothesis is that social inequality may also exist in the general population with respect to reporting of cancer alarm symptoms. The aim of this study was to investigate possible associations between socioeconomic and demographic determinants and reporting of common cancer alarm symptoms. Methods A cross-sectional questionnaire survey was performed based on a stratified sample of the Danish general population. A total of 13 777 randomly selected persons aged 20 years and older participated. Our main outcome measures were weighted prevalence estimates of self-reporting one of the following cancer alarm symptoms during the preceding 12 months: a lump in the breast, coughing for more than 6 weeks, seen blood in urine, or seen blood in stool. Logistic regression models were used to calculate unadjusted and adjusted odds ratios with 95% confidence intervals for the associations between each covariate and reporting of cancer alarm symptoms. Results A total of 2 098 (15.7%) of the participants reported one or more cancer alarm symptoms within the preceding 12 months. Women, subjects out of the workforce, and subjects with a cancer diagnosis had statistically significantly higher odds of reporting one or more cancer alarm symptoms. Subjects with older age and subjects living with a partner had lower odds of reporting one or more cancer alarm symptoms. When analysing the four alarm symptoms of cancer separately most tendencies persisted. Conclusions Socioeconomic and demographic determinants are associated with self-reporting of common cancer alarm symptoms. PMID:22914003

Obesity has been associated with higher risk of asthma and asthma severity both in children and adults. However, studies evaluating the relation between obesity and rhinitis have yielded conflicting results. We performed a cross-sectional study of obesity indicators and rhinitis using data from 8165 participants in the 2005-2006 National Health and Nutrition Examination Survey. Allergic rhinitis was defined as physician-diagnosed hay fever or allergy, the presence of symptoms in the past 12 months, and at least 1 positive allergen-specific IgE level. Nonallergic rhinitis was defined as a physician's diagnosis and symptoms but no positive allergen-specific IgE levels. Multivariate regression was used to assess the relationship between obesity and rhinitis in children and adults. In adults, overweight or obesity was associated with increased odds of nonallergic rhinitis (adjusted odds ratio, 1.43; 95% CI, 1.06-1.93; P = .02). Similarly, central obesity was associated with increased odds of nonallergic rhinitis in adults (adjusted odds ratio, 1.61; 95% CI, 1.20-2.16; P < .01). In an analysis stratified by sex, the observed associations were attenuated and became nonstatistically significant in female adults but remained significant in male adults. Overweight, obesity, or central obesity were not associated with allergic rhinitis in adults. In children, central obesity was associated with reduced odds of allergic rhinitis (adjusted odds ratio, 0.35; 95% CI, 0.19-0.64; P < .01). After stratification by sex, this association was similar in female and male children. In adults, obesity is associated with increased odds of nonallergic rhinitis, particularly in male subjects. In children, central obesity is associated with reduced odds of allergic rhinitis, regardless of sex. Copyright © 2016 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc.

We aimed to examine the prevalence of several types of childhood adversity across adult cohorts, whether age moderates the effect of childhood adversity on mental health, the relationship between childhood adversity and psychopathology among older adults, the dose-response relationship between number of types of childhood adversities and mental disorders in later life, and whether lifetime mental health treatment reduces the odds of psychopathology among older survivors of childhood adversity. In a population-based, cross-sectional study on a nationally representative U.S. sample, we studied 34,653 community-dwelling Americans 20 years and older, including 7,080 adults 65 years and older from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. Trained lay interviewers assessed past-year mood and anxiety disorders and lifetime personality disorders. Participants self-reported childhood adversity based on questions from the Adverse Childhood Experiences Study. Childhood adversity was prevalent across five age cohorts. In our adjusted models, age did not moderate the effect of childhood adversity on mental disorders. Older adults who experienced childhood adversity had higher odds of having mood (odds ratio: 1.73; 95% confidence interval: 1.32-2.28), anxiety (odds ratio: 1.48; 95% confidence interval: 1.20-1.83), and personality disorders (odds ratio: 2.11; 95% confidence interval: 1.75-2.54) after adjusting for covariates. An increasing number of types of childhood adversities was associated with higher odds of personality disorders and somewhat higher odds of anxiety disorders. Treatment-seeking was associated with a reduced likelihood of anxiety and, especially, mood disorders in older adult childhood adversity survivors. These results emphasize the importance of preventing childhood adversity and intervening once it occurs to avoid the negative mental health effects that can last into old age.

Congenital anomalies are a leading cause of infant mortality and are important contributors to subsequent morbidity. Studies suggest associations between environmental contaminants and some anomalies, although evidence is limited. We aimed to investigate whether ambient air pollutant and traffic exposures in early gestation contribute to the risk of selected congenital anomalies in the San Joaquin Valley of California, 1997-2006. Seven exposures and 5 outcomes were included for a total of 35 investigated associations. We observed increased odds of neural tube defects when comparing the highest with the lowest quartile of exposure for several pollutants after adjusting for maternal race/ethnicity, education, and multivitamin use. The adjusted odds ratio for neural tube defects among those with the highest carbon monoxide exposure was 1.9 (95% confidence interval: 1.1, 3.2) compared with those with the lowest exposure, and there was a monotonic exposure-response across quartiles. The highest quartile of nitrogen oxide exposure was associated with neural tube defects (adjusted odds ratio = 1.8, 95% confidence interval: 1.1, 2.8). The adjusted odds ratio for the highest quartile of nitrogen dioxide exposure was 1.7 (95% confidence interval: 1.1, 2.7). Ozone was associated with decreased odds of neural tube defects. Our results extend the limited body of evidence regarding air pollution exposure and adverse birth outcomes.

We examined the knowledge regarding heavy drinking and smoking as risk factors of stroke according to drinking/smoking habits among randomly selected Japanese general population. The Japan Stroke Association and co-researchers have performed a large-scale educational intervention to improve knowledge concerning stroke from 2006 to 2008. Prior to above-mentioned intervention, we conducted mail-surveillance on knowledge about stroke in 11,306 randomly selected residents aged 40 to 74. We assessed the relationship between drinking/smoking habits and knowledge regarding heavy drinking and smoking as risk factors by using the chi-square test and multiple logistic regression analysis adjusting for age, sex, area, employment, living situation, history of stroke and other stroke related diseases, history of liver disease, family history of stroke and drinking (non-drinker / ex-drinker / occasional drinker / habitual drinker) / smoking habits (non-smoker / ex-smoker / current smoker). Total 5,540 subjects (49.0%) participated in this study. Ex-smokers and current smokers had better knowledge regarding smoking as a risk factor of stroke than non-smokers (odds ratio and 95% confidence intervals: 1.89, 1.55-2.31, 1.76, 1.45-2.12, respectively). There was no difference between habitual drinkers and non-drinkers in their knowledge, whereas current smokers had greater knowledge regarding smoking than nonsmokers. Accordingly, it is suggested that it will be necessary for habitual drinkers to be enlightened regarding heavy drinking as a risk factor of stroke and for current smokers to be provided with information regarding not only these risks but also the specific strategies for invoking behavioral changes.

Dengue results in high morbidity and mortality globally. The knowledge, attitude and practices (KAP) of dengue management, including diagnosis, among primary care physicians (PCPs) are important to reduce dengue transmission and burden. However, there is a lack of understanding on the impact of dengue epidemic on dengue management. Hence, the aim of this study is to examine the changes in KAP on dengue management among PCPs before and after the largest dengue epidemic in 2013 in Singapore. Surveys were mailed to 2000 and 1514 PCPs registered under the Singapore Medical Council in March of year 2011 and 2014, respectively. Survey data were then collected between April and June of that year. Chi-square or Fisher's exact test was used for comparing categorical variables. A multivariate logistic regression model was implemented to determine independent factors for frequent use of dengue diagnostic tests (DDTs). All tests were conducted at 5% level of significance. Adjusted odds ratio and corresponding 95% confidence intervals were reported, where applicable. Qualitative data were descriptively coded for themes and analysis. Among PCPs surveyed in 2011 and 2014, 89.9% and 86% had good knowledge on dengue management respectively. The usage of DDTs had increased significantly in 2014 (N = 164;56%) as compared to 2011 (N = 107;29.5%) in both private and public clinics (p < 0.001). Dengue Duo point-of-care test (POCT) kits was independently associated with frequent use of DDTs (adjusted odds ratio = 2.15; 95% confidence interval = 1.25-3.69). There was a significant reduction in referral of dengue patients to hospital (31.4% in 2011; 13.3% in 2014; p < 0.001), and a significant increase in frequency of clinic follow-ups (18.4% in 2011; 28.5% in 2014; p = 0.003). One key theme highlighted was that dengue management can be improved with availability of POCT kit, better awareness of the disease and any revised clinical guidelines. The knowledge on dengue management remained high, while the attitude and practices, particularly on the usage of DDTs improved significantly after a large epidemic. Furthermore, PCPs had more confident in managing dengue patients in primary care settings and in educating patients on the importance of vector control and dengue warning signs to reduce dengue transmission and burden.

Atopic disease is hypothesized to be protective against several malignancies, including childhood/adolescent leukemia. To summarize the available epidemiologic evidence, the authors performed a meta-analysis of associations between atopy/allergies, asthma, eczema, hay fever, and hives and childhood/adolescent leukemia, acute lymphoblastic leukemia (ALL), and acute myeloid leukemia (AML). They searched MEDLINE literature (1952–March 2009) and queried international experts to identify eligible studies. Ten case-control studies were included. Summary odds ratios and 95% confidence intervals were computed via random-effects models. Odds ratios for atopy/allergies were 1.42 (95% confidence interval (CI): 0.60, 3.35) for 3 studies of leukemia overall, 0.69 (95% CI: 0.54, 0.89) for 6 studies of ALL, and 0.87 (95% CI: 0.62, 1.22) for 2 studies of AML, with high levels of heterogeneity detected for leukemia overall and ALL. Inverse associations were observed for ALL and asthma (odds ratio (OR) = 0.79, 95% CI: 0.61, 1.02), eczema (OR = 0.74, 95% CI: 0.58, 0.96), and hay fever (OR = 0.55, 95% CI: 0.46, 0.66) examined separately. Odds ratios for ALL differed by study design, exposure data source, and latency period, indicating that these factors affect study results. These results should be interpreted cautiously given the modest number of studies, substantial heterogeneity, and potential exposure misclassification but are useful in designing future research.

To examine whether maternal socioeconomic status, as indicated by maternal educational level, is associated with preeclampsia, and if so, to what extent known risk factors for preeclampsia mediate the effect of educational level. In the Generation R Study, a population-based cohort study, we examined data of 3547 pregnant women. Odds ratios of preeclampsia for low, mid-low and mid-high educational level compared with high educational level were calculated after adjustment for confounders and additional adjustment for a selection of potential mediators (family history, material factors, psychosocial factors, substance use, working conditions, preexisting medical conditions, maternal anthropometrics and blood pressure at enrollment) that individually caused more than 10% change in the odds ratio for low education. Adjusted for the confounding effects of age, gravidity and multiple pregnancy, women with low educational level were more likely to develop preeclampsia (odds ratio 5.12; 95% confidence interval: 2.20, 11.93) than women with high educational level. After additional adjustment for financial difficulties, smoking in pregnancy, working conditions, body mass index and blood pressure at enrollment, the odds ratio was 4.91 (95% confidence interval: 1.93, 12.52). Low maternal socioeconomic status is a strong risk factor for preeclampsia. Only a small part of this association can be explained by the mediating effects of established risk factors for preeclampsia. Further research is needed to disentangle the pathway from low socioeconomic status to preeclampsia.

This study was undertaken to determine the perinatal predictors of cerebral palsy in extremely low birthweight infants (<1000 g). A case control study of infants with birthweight of less than 1000 g (19 with cerebral palsy and 38 controls) who survived beyond 18-22 months of corrected age was performed. Outcome variables included maternal demographics, obstetric complications, and neonatal outcome (gestational age at delivery, birthweight, Apgar scores, intrauterine growth restriction, respiratory distress syndrome, intraventricular hemorrhage, and neonatal sepsis). Data analysis consisted of t tests, chi2, and analysis of variance when appropriate. There were no significant differences between cerebral palsy and control groups with regard to mode of delivery, Apgar scores, preeclampsia, antenatal vaginal bleeding, or the use of magnesium sulfate. However, male gender (odds ratio 3.70; 95% CI 1.05-12.5), primigravid status (odds ratio 5.52; 95% CI 1.67-18.3), early neonatal sepsis (odds ratio 12.9; 95% CI 2.94-57.2) and chorioamnionitis, both clinical and histologic (odds ratio 3.71; 95% CI 1.16-11.9) were significantly associated with the development of cerebral palsy. The strong association between cerebral palsy and chorioamnionitis, as well as early neonatal sepsis, remain significant after adjustment for primigravid status and male gender. In extremely low birthweight infants, cerebral palsy was strongly associated with chorioamnionitis, early neonatal sepsis, male gender, and primigravid status.

Clubfoot, a common major structural malformation, develops early in gestation. Epidemiologic studies have identified higher risks among boys, first-born children, and babies with a family history of clubfoot, but studies of risks associated with maternal exposures are lacking. We conducted the first large-scale, population-based, case-control study of clubfoot with detailed information on maternal medication use in pregnancy. Study subjects were ascertained from birth defect registries in Massachusetts, New York, and North Carolina during 2007–2011. Cases were 646 mothers of children with clubfoot without other major structural malformations (i.e., isolated clubfoot); controls were mothers of 2,037 children born without major malformations. Mothers were interviewed within 12 months of delivery about medication use, including product, timing, and frequency. Odds ratios were estimated for exposure to 27 medications in pregnancy months 2–4 after adjustment for study site, infant sex, first-born status, body mass index (weight (kg)/height (m)2), and smoking. Odds ratios were less than 1.20 for 14 of the medications; of the remainder, most odds ratios were only slightly elevated (range, 1.21–1.66), with wide confidence intervals. The use of antiviral drugs was more common in clubfoot cases than in controls (odds ratio = 4.22, 95% confidence interval: 1.52, 11.73). Most of these results are new findings and require confirmation in other studies. PMID:24824985

The associations between childhood acute lymphoblastic leukemia (ALL) and several proxies of early stimulation of the immune system, that is, day-care center attendance, birth order, maternally reported common infections in infancy, and breastfeeding, were investigated by using data from 11 case-control studies participating in the Childhood Leukemia International Consortium (enrollment period: 1980–2010). The sample included 7,399 ALL cases and 11,181 controls aged 2–14 years. The data were collected by questionnaires administered to the parents. Pooled odds ratios and 95% confidence intervals were estimated by unconditional logistic regression adjusted for age, sex, study, maternal education, and maternal age. Day-care center attendance in the first year of life was associated with a reduced risk of ALL (odds ratio = 0.77, 95% confidence interval: 0.71, 0.84), with a marked inverse trend with earlier age at start (P < 0.0001). An inverse association was also observed with breastfeeding duration of 6 months or more (odds ratio = 0.86, 95% confidence interval: 0.79, 0.94). No significant relationship with a history of common infections in infancy was observed even though the odds ratio was less than 1 for more than 3 infections. The findings of this large pooled analysis reinforce the hypothesis that day-care center attendance in infancy and prolonged breastfeeding are associated with a decreased risk of ALL. PMID:25731888

The goal was to determine the prevalence of and risk factors for disordered eating in an entry-level U.S. Army population. A cross-sectional survey of advanced individual training U.S. Army soldiers at Aberdeen Proving Ground, Maryland, was performed with an anonymous self-report survey containing demographic factors, history (including abuse and psychiatric treatment), and Eating Attitudes Test-26. Of 1,184 advanced individual training soldiers approached, 1090 participated. The response rate was 91.2% (955 men and 135 women). Forty percent were overweight (body mass index of > or =25), 11% reported a psychiatric history, 26% reported a history of abuse, and 9.8% endorsed disordered eating (male, 7.0%; female, 29.6%), as defined by Eating Attitudes Test-26. Factors that placed soldiers at higher risk for disordered eating were female gender (odds ratio, 5.63; 95% confidence interval, 3.32-9.57; p < 0.00005), overweight (odds ratio, 3.06; 95% confidence interval, 1.92-4.89; p < 0.00005), previous psychiatric treatment (odds ratio, 1.87; 95% confidence interval, 1.04-3.36; p = 0.035), and history of verbal abuse (odds ratio, 2.02; 95% confidence interval, 1.16-3.51; p = 0.014). Our study shows a higher than expected rate of disordered eating in advanced individual training soldiers with identifiable risk factors. This indicates an important need for further study, effective screening, preventive counseling, and early intervention for treatment.

Occupational risk factors for Wilms' tumor

Bunin, G.; Kramer, S.; Nass, C.

A matched case-control study of Wilms' tumor investigated parental occupational risk factors. Cases diagnosed in 1970-1983 were identified through a population-based tumor registry and hospital registries in the Greater Philadelphia area. Controls were selected by random digit dialing and were matched to cases on race, birth date (+/- 3 years), and the area code and exchange of the case's telephone number at diagnosis. Parents of 100 matched pairs were interviewed by telephone. Parents of patients and controls were generally similar in demographic characteristics, except that mothers differed in religion. Published schemes were used to group jobs into clusters of similarmore » exposures and to determine exposures from industry and job title. Analyses were done for preconception, pregnancy, and postnatal time periods. More case than control fathers had jobs in a cluster that includes machinists and welders (odds ratios (ORs) = 4.0-5.7, p less than or equal to 0.04). Paternal exposures to lead, silver, tin, and iron (some exposures of this cluster) were associated with Wilms' tumor in some analyses, with moderate odds ratios (ORs = 1.5-3.4). In general, the highest odds ratios were found for the preconception period among the genetic (prezygotic) cases. No maternal job clusters or exposures gave significantly elevated odds ratios. These results support a previous finding that lead is a risk factor, but not radiation, hydrocarbon, or boron exposures.« less

Recently, skeletal muscle depletion (sarcopenia) has been reported to influence postoperative outcomes after certain procedures. This study investigated the impact of sarcopenia on postoperative outcomes following pancreaticoduodenectomy (PD). We performed a retrospective study of consecutive patients (n = 219) who underwent PD at our institution between January 2007 and May 2013. Sarcopenia was evaluated using preoperative computed tomography. We evaluated postoperative outcomes and the influence of sarcopenia on short-term outcomes, especially infectious complications. Subsequently, multivariate analysis was used to assess the impact of prognostic factors (including sarcopenia) on postoperative infections. The mortality, major complication, and infectious complication rates for all patients were 1.4%, 16.4%, and 47.0%, respectively. Fifty-five patients met the criteria for sarcopenia. Sarcopenia was significantly associated with a higher incidence of in-hospital mortality (P = 0.004) and infectious complications (P < 0.001). In multivariate analyses, sarcopenia (odds ratio = 3.43; P < 0.001), preoperative biliary drainage (odds ratio = 2.20; P = 0.014), blood loss (odds ratio = 1.92; P = 0.048), and soft pancreatic texture (odds ratio = 3.71; P < 0.001) were independent predictors of postoperative infections. Sarcopenia is an independent preoperative predictor of infectious complications after PD. Clinical assessment combined with sarcopenia may be helpful for understanding the risk of postoperative outcomes and determining perioperative management strategies.

Context Short sleep duration is associated with obesity, but few studies have examined the relationship between obesity and specific physiological stages of sleep. Objective To examine specific sleep stages, including rapid eye movement (REM) sleep and stages 1 through 4 of non-REM sleep, in relation to overweight in children and adolescents. Design, Setting, and Participants A total of 335 children and adolescents (55.2% male; aged 7-17 years) underwent 3 consecutive nights of standard polysomnography and weight and height assessments as part of a study on the development of internalizing disorders (depression and anxiety). Main Outcome Measures Body mass index (calculated as weight in kilograms divided by height in meters squared) z score and weight status (normal, at risk for overweight, overweight) according to the body mass index percentile for age and sex. Results The body mass index z score was significantly related to total sleep time (β=-0.174), sleep efficiency (β=-0.027), and REM density (β=-0.256). Compared with normal-weight children, overweight children slept about 22 minutes less and had lower sleep efficiency, shorter REM sleep, lower REM activity and density, and longer latency to the first REM period. After adjustment for demographics, pubertal status, and psychiatric diagnosis, 1 hour less of total sleep was associated with approximately 2-fold increased odds of overweight (odds ratio=1.85), 1 hour less of REM sleep was associated with about 3-fold increased odds (odds ratio=2.91), and REM density and activity below the median increased the odds of overweight by 2-fold (odds ratio=2.18) and 3-fold (odds ratio=3.32), respectively. Conclusions Our results confirm previous epidemiological observations that short sleep time is associated with overweight in children and adolescents. A core aspect of the association between short sleep duration and overweight may be attributed to reduced REM sleep. Further studies are needed to investigate possible mechanisms underpinning the association between diminished REM sleep and endocrine and metabolic changes that may contribute to obesity.

The objective of the present study was to investigate if perinatal outcome differs with fetal sex in pregnancies with maternal Type 1 diabetes, Type 2 diabetes or gestational diabetes. This was a population-based cohort study, with data from the Medical Birth Registry in Sweden throughout the period 1998-2007. Singleton pregnancies with maternal Type 1 diabetes (n = 4092), Type 2 diabetes (n = 412) and gestational diabetes (n = 8602) were identified based on the International Classification of Diseases, 10th edition code. For comparison, 905 565 pregnancies without diabetes were included. The primary outcome was a composite outcome, consisting of any of the following diagnoses: perinatal mortality rate, major malformation, preterm delivery, acute respiratory disorders and neonatal hypoglycaemia. Logistic regression was used to obtain odds ratios for adverse outcomes in male offspring within the diabetic and reference cohorts, respectively. In pregnancies with diabetes, maternal characteristics did not differ with fetal sex, except for a higher rate of Caesarean delivery in male offspring of women with Type 1 diabetes. Male infants to mothers with Type 1 diabetes and gestational diabetes had significantly increased odds of respiratory disorders [adjusted odds ratio (confidence interval) Type 1 diabetes: 1.50 (1.12-2.02); gestational diabetes: 1.81 (1.27-2.57)]. Male infants to mothers with gestational diabetes also had significantly increased odds of major malformations [adjusted odds ratio: 1.44 (1.07-1.93)]. In offspring of mothers with Type 2 diabetes, odds ratios of most outcomes were higher in male infants; however, not significantly different from female infants. In pregnancies without diabetes, male infants had significantly higher odds of all adverse outcomes, except perinatal mortality rate. The risk of adverse perinatal outcome in offspring of mothers with Type 1 diabetes and gestational diabetes did not differ by sex, except for a higher risk in male infants for respiratory disorders. The risk of major malformations was also significantly increased in male offspring to mothers with gestational diabetes. In offspring of mothers with Type 2 diabetes, no significant differences between sexes were found. © 2014 The Authors. Diabetic Medicine © 2014 Diabetes UK.

Transient Elastography vs. Aspartate Aminotransferase to Platelet Ratio Index in Hepatitis C: A Meta-Analysis.

PubMed

Mattos, A Z; Mattos, A A

Many different non-invasive methods have been studied with the purpose of staging liver fibrosis. The objective of this study was verifying if transient elastography is superior to aspartate aminotransferase to platelet ratio index for staging fibrosis in patients with chronic hepatitis C. A systematic review with meta-analysis of studies which evaluated both non-invasive tests and used biopsy as the reference standard was performed. A random-effects model was used, anticipating heterogeneity among studies. Diagnostic odds ratio was the main effect measure, and summary receiver operating characteristic curves were created. A sensitivity analysis was planned, in which the meta-analysis would be repeated excluding each study at a time. Eight studies were included in the meta-analysis. Regarding the prediction of significant fibrosis, transient elastography and aspartate aminotransferase to platelet ratio index had diagnostic odds ratios of 11.70 (95% confidence interval = 7.13-19.21) and 8.56 (95% confidence interval = 4.90-14.94) respectively. Concerning the prediction of cirrhosis, transient elastography and aspartate aminotransferase to platelet ratio index had diagnostic odds ratios of 66.49 (95% confidence interval = 23.71-186.48) and 7.47 (95% confidence interval = 4.88-11.43) respectively. In conclusion, there was no evidence of significant superiority of transient elastography over aspartate aminotransferase to platelet ratio index regarding the prediction of significant fibrosis, but the former proved to be better than the latter concerning prediction of cirrhosis.

We evaluated the association between radiographically-assessed extension and density of root canal fillings and post-operative apical radiolucencies (AR) using data from 288 participants in the Veterans Affairs Dental Longitudinal Study. Study subjects were not VA patients; all received their medical and dental care in the private sector. Generalized Estimating Equations were used to account for multiple teeth within subjects and to control for covariates of interest. Defective root filling density was associated with increased odds of post-operative AR among teeth with no pre-operative AR (Odds Ratio=3.0, 95%CI=1.3–7.1), though pre-operative AR was the strongest risk factor for post-operative AR (Odds Ratio=29.2, 95%CI=13.6–63.0 among teeth with ideal density). Compared to well-extended root fillings, neither over- nor under-extended root fillings separately were related to post-operative AR, but when those two categories were collapsed into one “poorly-extended” category, poor extension was related to post-operative AR (Odds Ratio=1.8, 95%CI=1.1–3.2).

Migration is suspected to increase risk for depressive and anxiety disorders. To test the hypothesized increase in risk for depressive and anxiety disorders after arrival in the United States among Mexican migrants. We combined data from surveys conducted separately in Mexico and the United States that used the same diagnostic interview. Discrete time survival models were specified to estimate the relative odds of first onset of depressive disorders (major depressive episode and dysthymia) and anxiety disorders (generalized anxiety disorder, social phobia, panic disorder, and posttraumatic stress disorder) among migrants after their arrival in the United States compared with nonmigrant Mexicans who have a migrant in their immediate family. Population surveys in the United States and Mexico. Two thousand five hundred nineteen nonmigrant family members of migrants in Mexico and 554 Mexican migrants in the United States. First onset of any depressive or anxiety disorder. After arrival in the United States, migrants had a significantly higher risk for first onset of any depressive or anxiety disorder than did nonmigrant family members of migrants in Mexico (odds ratio, 1.42; 95% confidence interval, 1.04-1.94). Associations between migration and disorder varied across birth cohorts. Elevated risk among migrants relative to nonmigrants was restricted to the 2 younger cohorts (those aged 18-25 or 26-35 years at interview). In the most recent birth cohort, the association between migration and first onset of any depressive or anxiety disorder was particularly strong (odds ratio, 3.89; 95% confidence interval, 2.74-5.53). This is, to our knowledge, the first study to compare risk for first onset of psychiatric disorder between representative samples of migrants in the United States and nonmigrants in Mexico. The findings are consistent with the hypothesized adverse effect of migration from Mexico to the United States on the mental health of migrants, but only among migrants in recent birth cohorts.

Asian Americans have lower colorectal cancer (CRC) screening rates than non-Hispanic white individuals. Hmong Americans have limited socioeconomic resources and literacy. The current randomized controlled trial was conducted to determine whether bilingual/bicultural lay health educator (LHE) education could increase CRC screening among Hmong Americans. A cluster randomized controlled trial was conducted among Hmong Americans in Sacramento, California. LHEs and recruited participants were randomized to intervention or control groups. The intervention group received CRC education over 3 months delivered by an LHE. The control group received education regarding nutrition and physical activity delivered by a health educator. The outcomes were changes in self-reported ever-screening and up-to-date CRC screening after 6 months. All 329 participants were foreign-born with mostly no formal education, limited English proficiency, and no employment. The majority of the participants were insured and had a regular source of health care. The intervention group experienced greater changes after the intervention than the control group for ever-screening (P = .068) and being up-to-date with screening (P<.0001). In multivariable regression analyses, the intervention group demonstrated a greater increase than the control group in reporting ever-screening (adjusted odds ratio, 1.73; 95% confidence interval, 1.07-2.79) and being up-to-date with screening (adjusted odds ratio, 1.71; 95% confidence interval, 1.26-2.32). Individuals who had health insurance were found to have >4 times the odds of receiving screening, both ever-screening and up-to-date screening. A higher CRC knowledge score mediated the intervention effect for both screening outcomes. A culturally and linguistically appropriate educational intervention delivered by trained LHEs was found to increase CRC screening in an immigrant population with low levels of education, employment, English proficiency, and literacy.

To evaluate the efficacy of an in-language intervention of 2 lectures plus printed materials versus printed materials alone on knowledge and adherence to nutrition and physical activity guidelines among older Chinese Americans in San Francisco, California. From August 2010 to September 2013, we randomized 756 Chinese Americans aged 50 to 75 years to either lectures plus print (n = 361) or print (n = 357). Clusters were the participants recruited by each lay health worker. Intervention outcomes were changes in knowledge of recommended vegetable intake, fruit intake, and physical activity level and adherence to those recommendations from pre- to 6 months postintervention. The retention rate was 99%. At baseline, knowledge and adherence to recommendations were low. Print yielded increases in knowledge of recommended vegetable intake and physical activity level and adherence to fruit intake and physical activity recommendations. Lectures plus print had significant increases in all 6 outcomes. In multivariable models, lectures plus print was superior to print for knowledge of vegetable (adjusted odds ratio [AOR] = 12.61; 95% confidence interval [CI] = 6.50, 24.45) and fruit (AOR = 16.16; 95% CI = 5.61, 46.51) intake recommendations and adherence to vegetable intake recommendations (AOR = 5.53; 95% CI = 1.96, 15.58). In-language print materials, alone and combined with lectures, increased nutrition and physical activity knowledge and behaviors among older Chinese Americans.

Maternal periodontal disease is associated with adverse perinatal outcomes. Anxiety and depression adversely impact oral health in nonpregnant women; however, this association has not been evaluated during pregnancy, a time characterized by higher rates of anxiety and depression. Therefore, we examined the association between these factors and oral disease and oral healthcare utilization among 402 pregnant respondents to the 2010 Behavioral Risk Factor Surveillance System. Self-reported lifetime diagnoses of anxiety, depression, and current depression were assessed. Oral health outcomes included self-reported tooth loss and dental visits in the past year. One-fifth (21.2 percent) of respondents reported a tooth loss and 32.5 percent reported nonuse of oral health services. The prevalence of lifetime diagnosed anxiety and depression was 13.6 percent and 11.3 percent, respectively, whereas 10.6 percent reported current depression. After adjusting for risk factors, pregnant women with diagnosed anxiety had increased odds of one or more tooth loss [odds ratio (OR) = 3.30; 95 percent confidence interval (CI): 1.01-10.77] compared with those without the disorder. Similarly, after adjusting for socioeconomic factors, women with anxiety had increased odds of nonuse of oral health services (OR = 2.67; 95 percent CI: 1.03-6.90); however, this was no longer significant after adjusting for health behaviors and body mass index. We observed no significant association with depression. In this population-based sample, we found a two- to threefold increased odds of tooth loss and nonuse of oral health services among pregnant women with a lifetime diagnosis of anxiety. To our knowledge, this is the first study to examine these associations among pregnant women. © 2015 American Association of Public Health Dentistry.

To map the changing prevalence and predictors of psychological outcomes in affected communities 5 years following the Black Saturday bushfires in Victoria. Follow-up assessment of longitudinal cohort study in high, medium and non-affected communities in Victoria, Australia. Participants included 1017 respondents (Wave 1) interviewed via telephone and web-based survey between December 2011 and January 2013, and 735 (76.1%) eligible participants were retested between July and November 2014 (Wave 2). The survey included measures of fire-related and subsequent stressful events, probable posttraumatic stress disorder, major depressive episode, alcohol use and severe distress. There were reduced rates of fire-related posttraumatic stress disorder (8.7% vs 12.1%), general posttraumatic stress disorder (14.7% vs 18.2%), major depressive episode (9.0% vs 10.9%) and serious mental illness (5.4% vs 7.8%). Rates of resilience increased over time (81.8% vs 77.1%), and problem alcohol use remained high across Wave 1 (22.1%) and Wave 2 (21.4%). The most robust predictor of later development of fire-related posttraumatic stress disorder (odds ratio: 2.11; 95% confidence interval: [1.22, 3.65]), general posttraumatic stress disorder (odds ratio: 3.15; 95% confidence interval: [1.98, 5.02]), major depressive episode (odds ratio: 2.86; 95% confidence interval: [1.74, 4.70]), serious mental illness (odds ratio: 2.67; 95% confidence interval: [0.57, 1.72]) or diminished resilience (odds ratio: 2.01; 95% confidence interval: [1.32, 3.05]) was extent of recent life stressors. Although rates of mental health problems diminished over time, they remained higher than national levels. Findings suggest that policy-makers need to recognize that the mental health consequences of disasters can persist for many years after the event and need to allocate resources towards those who are most at risk as a result of substantive losses and ongoing life stressors.

Dating applications (apps) on smartphones have become increasingly popular. The aim of this study was to explore the association between the use of dating apps and risky sexual behaviours. Data were collected in four university campuses in Hong Kong. Subjects completed a structured questionnaire asking about the use of dating apps, sexual behaviours, and sociodemographics. Multiple linear and logistics regressions were used to explore factors associated with sexual risk behaviours. Six hundred sixty-six subjects were included in the data analysis. Factors associated with having unprotected sexual intercourse with more lifetime sexual partners included use of dating apps (β = 0.93, p<0.01), having one's first sexual intercourse before 16 years of age (β = 1.74, p<0.01), being older (β = 0.4, p<0.01), currently being in a relationship (= 0.69, p<0.05), having a monthly income at least HKD$5,000 (β = 1.34, p<0.01), being a current smoker (β = 1.52, p<0.01), and being a current drinker (β = 0.7, p<0.01). The results of a multiple logistic regression analysis found that users of dating apps (adjust odds ratio: 0.52, p<0.05) and current drinkers (adjust odds ratio: 0.40, p<0.01) were less likely to have consistent condom use. Users of dating apps (adjust odds ratio: 1.93, p<0.05), bisexual/homosexual subjects (adjust odds ratio: 2.57, p<0.01) and female subjects (adjust odds ratio: 2.00, p<0.05) were more likely not to have used condoms the last time they had sexual intercourse. The present study found a robust association between using dating apps and sexual risk behaviours, suggesting that app users had greater sexual risks. Interventions that can target app users so that they can stay safe when seeking sexual partners through dating apps should be developed.

Absorbable synthetic versus catgut suture material for perineal repair

PubMed Central

Kettle, Christine

2014-01-01

Background Approximately 70% of women will experience some degree of perineal trauma following vaginal delivery and will require stitches. This may result in perineal pain and superficial dyspareunia. Objectives The objective of this review was to assess the effects of absorbable synthetic suture material as compared with catgut on the amount of short and long term pain experienced by mothers following perineal repair. Search strategy We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register. Selection criteria Randomised trials comparing absorbable synthetic (polyglycolic acid and polyglactin) with plain or chromic catgut suture for perineal repair in mothers after vaginal delivery. Data collection and analysis Trial quality was assessed independently by two reviewers. Data were extracted by one reviewer and checked by the second reviewer. Main results Eight trials were included. Compared with catgut, the polyglycolic acid and polyglactin groups were associated with less pain in first three days (odds ratio 0.62, 95% confidence interval 0.54 to 0.71). There was also less need for analgesia (odds ratio 0.63, 95% confidence interval 0.52 to 0.77) and less suture dehiscence (odds ratio 0.45, 95% confidence interval 0.29 to 0.70). There was no significant difference in long term pain (odds ratio 0.81, 95% confidence interval 0.61 to 1.08). Removal of suture material was significantly more common in the polyglycolic acid and polyglactin groups (odds ratio 2.01, 95% confidence interval 1.56 to 2.58). There was no difference in the amount of dyspareunia experienced by women. Authors’ conclusions Absorbable synthetic suture material (in the form of polyglycolic acid and polyglactin sutures) for perineal repair following childbirth appears to decrease women’s experience of short-term pain. The length of time taken for the synthetic material to be absorbed is of concern. A trial addressing the use of polyglactin has recently been completed and this has been included in this updated review. PMID:10796081

BACKGROUND Organizational leaders and scholars have issued calls for the medical profession to refocus its efforts on fulfilling the core tenets of professionalism. A key element of professionalism is participation in community affairs. OBJECTIVE To measure physician voting rates as an indicator of civic participation. DESIGN Cross-sectional survey of a subgroup of physicians from a nationally representative household survey of civilian, noninstitutionalized adult citizens. PARTICIPANTS A total of 350,870 participants in the Current Population Survey (CPS) November Voter Supplement from 1996–2002, including 1,274 physicians and 1,886 lawyers; 414,989 participants in the CPS survey from 1976–1982, including 2,033 health professionals. MEASUREMENTS Multivariate logistic regression models were used to compare adjusted physician voting rates in the 1996–2002 congressional and presidential elections with those of lawyers and the general population and to compare voting rates of health professionals in 1996–2002 with those in 1976–1992. RESULTS After multivariate adjustment for characteristics known to be associated with voting rates, physicians were less likely to vote than the general population in 1998 (odds ratio 0.76; 95% confidence interval [CI] 0.59–0.99), 2000 (odds ratio 0.64; 95% CI 0.44–0.93), and 2002 (odds ratio 0.62; 95% CI 0.48–0.80) but not 1996 (odds ratio 0.83; 95% CI 0.59–1.17). Lawyers voted at higher rates than the general population and doctors in all four elections (P < .001). The pooled adjusted odds ratio for physician voting across the four elections was 0.70 (CI 0.61–0.81). No substantial changes in voting rates for health professionals were observed between 1976–1982 and 1996–2002. CONCLUSIONS Physicians have lower adjusted voting rates than lawyers and the general population, suggesting reduced civic participation. PMID:17443365

Study Objectives: We aimed to explore the incidence and persistence of insomnia, the associated risk factors, and the potential bidirectional association of insomnia with depression, anxiety, and sleepiness in rural Chinese adolescents. Design: School-based prospective study. Setting: Five high schools in rural China. Participants: There were 2,787 adolescents studied. Interventions: N/A. Measures and Results: Insomnia was defined as having a score of equal to or higher than nine in the Insomnia Severity Index as validated in Chinese adolescents. Depression, anxiety, and sleepiness were determined by the Beck Depression Inventory (BDI), Zung Self-Rating Anxiety Scale (SAS), and Epworth Sleepiness Scale (ESS), respectively. The incidence and persistence rates of insomnia were 16.0% and 41.0%, respectively. Multivariate analyses in logistic regression models revealed that new incidence of insomnia was significantly associated with age, living in a rural area, habitual daytime napping, high life events, anxiety, and depression at baseline (range adjusted odds ratio = 1.12-1.61), whereas the persistence of insomnia was positively associated with age, female sex, high life events, and depression at baseline (range adjusted odds ratio = 1.26-1.55) but negatively associated with living in a rural area (odds ratio = 0.59). Insomnia at baseline could predict new onsets of both depression (odds ratio = 1.45) and anxiety (odds ratio = 1.98) but not sleepiness at follow-up after adjustment for age, sex, and baseline symptoms. The results in cross-lagged analyses further supported these observations in the bidirectional associations of insomnia with depression, anxiety, and sleepiness. Conclusions: Insomnia has considerable incidence and persistence rates in Chinese adolescents. We have identified several risk factors for the incidence and persistence of insomnia. There are bidirectional associations of insomnia with depression and anxiety but not sleepiness. Citation: Luo C; Zhang J; Pan J. One-year course and effects of insomnia in rural Chinese adolescents.

To define better the prevalence and pathophysiology of lymphoceles following renal transplantation, we prospectively evaluated 118 consecutive renal transplants performed in 115 patients (96 cadaveric, 22 living-related, 7 secondary and 111 primary). Ultrasonography was performed post-operatively and during rehospitalizations or whenever complications occurred. Perirenal fluid collections were identified in 43 patients (36%). Lymphoceles with a diameter of 5 cm. or greater were identified in 26 of 118 cases (22%). Eight patients (6.8%) had symptomatic lymphoceles requiring therapy. The interval for development of symptomatic lymphoceles was 1 week to 3.7 years (median 10 months). Risk factors for the development of lymphoceles were examined by univariate and multivariate analysis, and included patient age, sex, source of transplants (cadaver versus living-related donor), retransplantation, tissue match (HLA-B/DR), type of preservation, arterial anastomosis, occurrence of acute tubular necrosis-delayed graft function, occurrence of rejection, and use of high dose corticosteroids. Univariate analysis showed a significant risk for the development of lymphoceles in transplants with acute tubular necrosis-delayed graft function (odds ratio 4.5, p = 0.004), rejection (odds ratio 25.1 p < 0.001) and high dose steroids (odds ratio 16.4, p < 0.001). When applying multivariate analyses using stepwise logistic regression, only rejection was associated with a significant risk for lymphoceles (symptomatic lymphoceles--odds ratio 25.08, p = 0.0003, all lymphoceles--odds ratio 75.24, p < 0.0001). When adjusting for rejection, no other risk factor came close to being significant (least p = 0.4). Therapy included laparoscopic peritoneal marsupialization and drainage in 1 patient, incisional peritoneal drainage in 4 and percutaneous external drainage in 3 (infected). All symptomatic lymphoceles were successfully treated without sequelae to grafts or patients. We conclude that allograft rejection is the most significant factor contributing to the development of lymphoceles. Therapy of symptomatic lymphoceles should be individualized according to the presence or absence of infection.

Previous findings of the association between socioeconomic deprivation and mortality after ischemic stroke are inconsistent. There is a lack of data on the association with combined low education, occupational class, and income. We assessed the associations of three indicators with mortality. We examined data from the China National Stroke Registry, recording all stroke patients occurred between September 2007 and August 2008. Baseline socioeconomic deprivation was measured using low levels of education at <6 years, occupation as manual laboring, and average family income per capita at ≤¥1000 per month. A total of 12,246 patients with ischemic stroke were analyzed. In a 12-month follow-up 1640 patients died. After adjustment for age, sex, cardiovascular risk factors, severity of stroke, and prehospital medications, odds ratio for mortality in patients with low education was 1.25 (95%CI 1.05-1.48), manual laboring 1.37 (1.09-1.72), and low income 1.19 (1.03-1.37). Further adjustment for acute care and medications in and after hospital made no substantial changes in these odds ratios, except a marginal significant odds ratio for low income (1.15, 0.99-1.33). The odds ratio for low income was 1.27 (1.01-1.60) within patients with high education. Compared with no socioeconomic deprivation, the odds ratio in patients with socioeconomic deprivation determined by any one indicator was 1.33 (1.11-1.59), by any two indicators 1.36 (1.10-1.69), and by all three indicators 1.56 (1.23-1.97). There are significant inequalities in survival after ischemic stroke in China in terms of social and material forms of deprivation. General socioeconomic improvement, targeting groups at high risk of mortality is likely to reduce inequality in survival after stroke. © 2016 World Stroke Organization.

The study objective was to identify the predictors of outcomes in a contemporary cohort of patients from the Reduction in cardiovascular Events by acaDesine in patients undergoing CABG (RED-CABG) trial. Despite the increasing risk profile of patients who undergo coronary artery bypass grafting, morbidity and mortality have remained low, and identification of the current predictors of adverse outcomes may permit new treatments to further improve outcomes. The RED-CABG trial was a multicenter, randomized, double-blind, placebo-controlled study that determined that acadesine did not reduce adverse events in moderately high-risk patients undergoing nonemergency coronary artery bypass grafting. The primary efficacy end point was a composite of all-cause death, nonfatal stroke, or the need for mechanical support for severe left ventricular dysfunction through postoperative day 28. Logistic regression modeling with stepwise variable selection identified which prespecified baseline characteristics were associated with the primary outcome. A second logistic model included intraoperative variables as potential covariates. The 4 independent preoperative risk factors predictive of the composite end point were (1) a history of heart failure (odds ratio, 2.9); (2) increasing age (odds ratio, 1.033 per decade); (3) a history of peripheral vascular disease (odds ratio, 1.6); and (4) receiving aspirin before coronary artery bypass grafting (odds ratio, 0.5), which was protective. The duration of the cardiopulmonary bypass (odds ratio, 1.8) was the only intraoperative variable that contributed to adverse outcomes. Patients who had heart failure and preserved systolic function had a similar high risk of adverse outcomes as those with low ejection fractions, and new approaches may mitigate this risk. Recognition of patients with excessive atherosclerotic burden may permit perioperative interventions to improve their outcomes. The contemporary risks of coronary artery bypass grafting have changed, and their identification may permit new methods to improve outcomes.

Time-to-surgery from cancer diagnosis has increased in the United States. We aimed to determine the association between time-to-surgery and oncologic outcomes in patients with resectable pancreatic ductal adenocarcinoma undergoing upfront surgery. The 2004-2012 National Cancer Database was reviewed for patients undergoing curative-intent surgery without neoadjuvant therapy for clinical stage I-II pancreatic ductal adenocarcinoma. A multivariable Cox model with restricted cubic splines was used to define time-to-surgery as short (1-14 days), medium (15-42), and long (43-120). Overall survival was examined using Cox shared frailty models. Secondary outcomes were examined using mixed-effects logistic regression models. Of 16,763 patients, time-to-surgery was short in 34.4%, medium in 51.6%, and long in 14.0%. More short time-to-surgery patients were young, privately insured, healthy, and treated at low-volume hospitals. Adjusted hazards of mortality were lower for medium (hazard ratio 0.94, 95% confidence interval, .90, 0.97) and long time-to-surgery (hazard ratio 0.91, 95% confidence interval, 0.86, 0.96) than short. There were no differences in adjusted odds of node positivity, clinical to pathologic upstaging, being unresectable or stage IV at exploration, and positive margins. Medium time-to-surgery patients had higher adjusted odds (odds ratio 1.11, 95% confidence interval, 1.03, 1.20) of receiving an adequate lymphadenectomy than short. Ninety-day mortality was lower in medium (odds ratio 0.75, 95% confidence interval, 0.65, 0.85) and long time-to-surgery (odds ratio 0.72, 95% confidence interval, 0.60, 0.88) than short. In this observational analysis, short time-to-surgery was associated with slightly shorter OS and higher perioperative mortality. These results may suggest that delays for medical optimization and referral to high volume surgeons are safe. Published by Elsevier Inc.

The Impacts of Using Smartphone Dating Applications on Sexual Risk Behaviours in College Students in Hong Kong

PubMed Central

2016-01-01

Dating applications (apps) on smartphones have become increasingly popular. The aim of this study was to explore the association between the use of dating apps and risky sexual behaviours. Data were collected in four university campuses in Hong Kong. Subjects completed a structured questionnaire asking about the use of dating apps, sexual behaviours, and sociodemographics. Multiple linear and logistics regressions were used to explore factors associated with sexual risk behaviours. Six hundred sixty-six subjects were included in the data analysis. Factors associated with having unprotected sexual intercourse with more lifetime sexual partners included use of dating apps (β = 0.93, p<0.01), having one’s first sexual intercourse before 16 years of age (β = 1.74, p<0.01), being older (β = 0.4, p<0.01), currently being in a relationship (= 0.69, p<0.05), having a monthly income at least HKD$5,000 (β = 1.34, p<0.01), being a current smoker (β = 1.52, p<0.01), and being a current drinker (β = 0.7, p<0.01). The results of a multiple logistic regression analysis found that users of dating apps (adjust odds ratio: 0.52, p<0.05) and current drinkers (adjust odds ratio: 0.40, p<0.01) were less likely to have consistent condom use. Users of dating apps (adjust odds ratio: 1.93, p<0.05), bisexual/homosexual subjects (adjust odds ratio: 2.57, p<0.01) and female subjects (adjust odds ratio: 2.00, p<0.05) were more likely not to have used condoms the last time they had sexual intercourse. The present study found a robust association between using dating apps and sexual risk behaviours, suggesting that app users had greater sexual risks. Interventions that can target app users so that they can stay safe when seeking sexual partners through dating apps should be developed. PMID:27828997

The objective of this review was to conduct a meta-analysis of all up-to-date randomised control trials to determine whether periodontal treatment during pregnancy has the potential of reducing preterm birth and low birth weight incidence. Bibliographic databases MEDLINE (1966-present), EMBASE (1980-present), CINAHL (1982-present) and the Cochrane library up to and including 2010 Issue 10 were searched. The reference list of included studies and reviews were also searched for additional literature. Eligible studies were, published and ongoing randomised control trials that compared pregnancy outcomes for pregnant women who received periodontal treatment during the prenatal period. Two of the investigators independently assessed the studies and then extracted and summarised data from eligible trials. Extracted data were entered into Review Manager software and analysed. A total of 5645 pregnant women participated in the 10 eligible trials. Meta-analysis found that periodontal treatment significantly lowered preterm birth (odd ratio 0.65; 95% confidence interval, 0.45-0.93; P = 0.02) and low birth weight (odd ratio 0.53; 95% confidence interval, 0.31-0.92; P = 0.02) rates while no significant difference was found for spontaneous abortion/stillbirth (odd ratio 0.71; 95% confidence interval, 0.43-1.16; P = 0.17). Moderate heterogeneity was observed among the studies for preterm birth and low birth weight. Subgroup analysis showed significant effect of periodontal treatment in pregnant women with low rate of previous preterm birth/low birth weight (odd ratio 0.35; 95% confidence interval, 017-0.70; P = 0.003) and less severe periodontal disease (odd ratio 0.49; confidence interval, 028-0.87; P = 0.01) as defined by probing depth. The cumulative evidence suggests that periodontal treatment during pregnancy may reduce preterm birth and low birth weight incidence. However, these findings need to be further validated through larger more targeted randomised control trials. © 2011 The Authors.

To examine the clinical factors associated with increased opioid dose among mechanically ventilated children in the pediatric intensive care unit. Prospective, observational study with 100% accrual of eligible patients. Seven pediatric intensive care units from tertiary-care children's hospitals in the Collaborative Pediatric Critical Care Research Network. Four hundred nineteen children treated with morphine or fentanyl infusions. None. Data on opioid use, concomitant therapy, demographic and explanatory variables were collected. Significant variability occurred in clinical practices, with up to 100-fold differences in baseline opioid doses, average daily or total doses, or peak infusion rates. Opioid exposure for 7 or 14 days required doubling of the daily opioid dose in 16% patients (95% confidence interval 12%-19%) and 20% patients (95% confidence interval 16%-24%), respectively. Among patients receiving opioids for longer than 3 days (n = 225), this occurred in 28% (95% confidence interval 22%-33%) and 35% (95% confidence interval 29%-41%) by 7 or 14 days, respectively. Doubling of the opioid dose was more likely to occur following opioid infusions for 7 days or longer (odds ratio 7.9, 95% confidence interval 4.3-14.3; p < 0.001) or co-therapy with midazolam (odds ratio 5.6, 95% confidence interval 2.4-12.9; p < 0.001), and it was less likely to occur if morphine was used as the primary opioid (vs. fentanyl) (odds ratio 0.48, 95% confidence interval 0.25-0.92; p = 0.03), for patients receiving higher initial doses (odds ratio 0.96, 95% confidence interval 0.95-0.98; p < 0.001), or if patients had prior pediatric intensive care unit admissions (odds ratio 0.37, 95% confidence interval 0.15-0.89; p = 0.03). Mechanically ventilated children require increasing opioid doses, often associated with prolonged opioid exposure or the need for additional sedation. Efforts to reduce prolonged opioid exposure and clinical practice variation may prevent the complications of opioid therapy.

Objective  This study aims to assess the association of nursing overtime, nurse staffing, and unit occupancy with health care-associated infections (HCAIs) in the neonatal intensive care unit (NICU). Study Design  A 2-year retrospective cohort study was conducted for 2,236 infants admitted in a Canadian tertiary care, 51-bed NICU. Daily administrative data were obtained from the database "Logibec" and combined to the patient outcomes database. Median values for the nursing overtime hours/total hours worked ratio, the available to recommended nurse staffing ratio, and the unit occupancy rate over 3-day periods before HCAI were compared with days that did not precede infections. Adjusted odds ratios (aOR) that control for the latter factors and unit risk factors were also computed. Results  A total of 122 (5%) infants developed a HCAI. The odds of having HCAI were higher on days that were preceded by a high nursing overtime ratio (aOR, 1.70; 95% confidence interval [95% CI], 1.05-2.75, quartile [Q]4 vs. Q1). High unit occupancy rates were not associated with increased odds of infection (aOR, 0.85; 95% CI, 0.47-1.51, Q4 vs. Q1) nor were higher available/recommended nurse ratios (aOR, 1.16; 95% CI, 0.67-1.99, Q4 vs. Q1). Conclusion  Nursing overtime is associated with higher odds of HCAI in the NICU. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Background While many studies have evaluated the association between acute childhood leukemia and environmental factors, knowledge is limited. Ambient air pollution has been classified as a Group 1 carcinogen, but studies have not established whether traffic-related air pollution is associated with leukemia. The goal of our study was to determine if children with acute leukemia had higher odds of exposure to traffic-related air pollution at birth compared to controls. Methods We conducted a case-control study using the Oklahoma Central Cancer Registry to identify cases of acute leukemia in children diagnosed before 20 years of age between 1997 and 2012 (n=307). Controls were selected from birth certificates and matched to cases on week of birth (n=1,013). Using a novel satellite-based land-use regression model of nitrogen dioxide (NO2) and estimating road density based on the 2010 US Census, we evaluated the association between traffic-related air pollution and childhood leukemia using conditional logistic regression. Results The odds of exposure to the fourth quartile of NO2 (11.19–19.89 ppb) were similar in cases compared to controls after adjustment for maternal education (OR: 1.08, 95% CI: 0.75, 1.55). These estimates were stronger among children with acute myeloid leukemia (AML) than acute lymphoid leukemia, with a positive association observed among urban children with AML (4th quartile odds ratio: 5.25, 95% confidence interval: 1.09, 25.26). While we observed no significant association with road density, male cases had an elevated odds of exposure to roads at 500 m from the birth residence compared to controls (OR: 1.39, 95% CI: 0.93, 2.10), which was slightly attenuated at 750 m. Conclusions Although we observed no association overall between NO2 or road density, this was the first study to observe an elevated odds of exposure to NO2 among children with AML compared to controls suggesting further exploration of traffic-related air pollution and AML is warranted.

The purpose of this work was to determine relationships between BMI status at ages 4 to 5 years and mothers' and fathers' parenting dimensions and parenting styles. Participants were composed of all 4983 of the 4- to 5-year-old children in wave 1 of the nationally representative Longitudinal Study of Australian Children with complete BMI and maternal parenting data. Mothers and fathers self-reported their parenting behaviors on 3 multi-item continuous scales (warmth, control, and irritability) and were each categorized as having 1 of 4 parenting styles (authoritative, authoritarian, permissive, and disengaged) using internal warmth and control tertile cut points. Using a proportional odds model, odds ratios for children being in a higher BMI category were computed for mothers and fathers separately and together, after adjustment for factors associated with child BMI, including mothers' and fathers' BMI status. The sample was composed of 2537 boys and 2446 girls with a mean age 56.9 months; 15% were overweight and 5% were obese (International Obesity Task Force criteria). Mothers' parenting behaviors and styles were not associated in any model with higher odds of children being in a heavier BMI category, with or without multiple imputation to account for missing maternal BMI data. Higher father control scores were associated with lower odds of the child being in a higher BMI category. Compared with the reference authoritative style, children of fathers with permissive and disengaged parenting styles had higher odds of being in a higher BMI category. This article is the first, to our knowledge, to examine the parenting of both parents in relation to preschoolers' BMI status while also adjusting for parental BMI status. Fathers' but not mothers' parenting behaviors and styles were associated with increased risks of preschooler overweight and obesity. Longitudinal impacts of parenting on BMI gain remain to be determined.

Objective There is conflicting and limited literature on the effect of intraoperative resident involvement on surgical outcomes. Our study assessed effects of resident involvement on outcomes in patients undergoing neurosurgery. Methods We identified 33,977 adult neurosurgical cases from 374 hospitals in the 2006–2012 National Surgical Quality Improvement Program, a prospectively collected national database with established reproducibility and validity. Outcomes were compared according to resident involvement before and after 1:1 matching on procedure and perioperative risk factors. Results Resident involvement was documented in 13,654 cases. We matched 10,170 resident-involved cases with 10,170 attending-alone. In the matched sample, resident involvement was associated with increased surgery duration (average, 34 minutes) and slight increases in odds for prolonged hospital stay (odds ratio, 1.2; 95% confidence interval [CI], 1.2–1.3) and complications (odds ratio, 1.2; 95% CI, 1.1–1.3) including infections (odds ratio, 1.4; 95% CI, 1.2–1.7). Increased risk for infections persisted after controlling for surgery duration (odds ratio, 1.3; 95% CI, 1.1–1.5). The majority of cases were spine surgeries, and resident involvement was not associated with morbidity or mortality for malignant tumor and aneurysm patients. Training level of residents was not associated with differences in outcomes. Conclusion Resident involvement was more common in sicker patients undergoing complex procedures, consistent with academic centers undertaking more complex cases. After controlling for patient and intraoperative characteristics, resident involvement in neurosurgical cases continued to be associated with longer surgical duration and slightly higher infection rates. Longer surgery duration did not account for differences in infection rates. PMID:29656619

Depressive state has been reported to be significantly associated with higher-level functional capacity among community-dwelling elderly. However, few studies have investigated the associations among people with long-term care requirements. We aimed to investigate the associations between depressive state and higher-level functional capacity and obtain marginal odds ratios using propensity score analyses in people with long-term care requirements. We conducted a cross-sectional study based on participants aged ≥ 65 years (n = 545) who were community dwelling and used outpatient care services for long-term preventive care. We measured higher-level functional capacity, depressive state, and possible confounders. Then, we estimated the marginal odds ratios (i.e., the change in odds of impaired higher-level functional capacity if all versus no participants were exposed to depressive state) by logistic models using generalized linear models with the inverse probability of treatment weighting (IPTW) for propensity score and design-based standard errors. Depressive state was used as the exposure variable and higher-level functional capacity as the outcome variable. The all absolute standardized differences after the IPTW using the propensity scores were < 10% which indicated negligible differences in the mean or prevalence of the covariates between non-depressive state and depressive state. The marginal odds ratios were estimated by the logistic models with IPTW using the propensity scores. The marginal odds ratios were 2.17 (95%CI: 1.13-4.19) for men and 2.57 (95%CI: 1.26-5.26) for women. Prevention of depressive state may contribute to not only depressive state but also higher-level functional capacity.

Accurate identification of risk factors for calcific uremic arteriolopathy (CUA) is necessary to develop preventive strategies for this morbid disease. We investigated whether baseline factors recorded at hemodialysis initiation would identify patients at risk for future CUA in a matched case-control study using data from a large dialysis organization. Hemodialysis patients with newly diagnosed CUA (n=1030) between January 1, 2010, and December 31, 2014, were matched by age, sex, and race in a 1:2 ratio to hemodialysis patients without CUA (n=2060). Mean ages for patients and controls were 54 and 55 years, respectively; 67% of participants were women and 49% were white. Median duration between hemodialysis initiation and subsequent CUA development was 925 days (interquartile range, 273–2185 days). In multivariable conditional logistic regression analyses, diabetes mellitus; higher body mass index; higher levels of serum calcium, phosphorous, and parathyroid hormone; and nutritional vitamin D, cinacalcet, and warfarin treatments were associated with increased odds of subsequent CUA development. Compared with patients with diabetes receiving no insulin injections, those receiving insulin injections had a dose-response increase in the odds of CUA involving lower abdomen and/or upper thigh areas (odds ratio, 1.49; 95% confidence interval, 1.03 to 2.51 for one or two injections per day; odds ratio, 1.88; 95% confidence interval, 1.30 to 3.43 for 3 injections per day; odds ratio, 3.74; 95% confidence interval, 2.28 to 6.25 for more than three injections per day), suggesting a dose-effect relationship between recurrent skin trauma and CUA risk. The presence of risk factors months to years before CUA development observed in this study will direct the design of preventive strategies and inform CUA pathobiology. PMID:27080977

The main outcome of this review was the association between a history of clinical chronic prostatitis (NIH category II or III) and a histologically confirmed diagnosis of prostate cancer. Crude odds ratios and 95% confidence intervals (CI) were calculated to analyze dichotomous data. For analysis of pooled data we adopted a random-effects model and the inverse variance weighing method. Heterogeneity was assessed by calculating the I2 value. Out of 2794 screened records, we retrieved 16 full-text articles written in English, reporting the data of 15 case-control studies, involving 422.943 patients. Pooled analysis resulted in a significant crude odds ratio of 1.83 (95% CI: 1.43 to 2.35; P < 0.00001). The total set of data showed considerable heterogeneity (I2 = 91%). Both the Egger's test and the Begg's test for funnel plot asymmetry did not reach statistical significance. The 'trim and fill' method applied to the funnel plot imputed 3 missing studies and the resulting adjusted estimate of the odds ratio was 2.12 (95% CI: 1.38 to 3.22). According to GRADE criteria, the overall quality of the meta-analysis data is low, mainly due to the presence of bias, confounders and extreme effect size outliers. Five among the included studies reported data assessed in 8015 African-American subjects. Pooled analysis resulted in a non-significant crude odds ratio of 1.59 (95% CI: 0.71 to 3.57; P = 0.26), and considerable heterogeneity (I2 = 90%). Meta-analysis of 15 case-control studies shows that a history of clinical chronic prostatitis can significantly increase the odds for prostate cancer in the general population, whereas such association in African-American individuals remains uncertain.

Eight of 17 districts of Shanghai have offered transportation and living allowances subsidies to patients with tuberculosis (TB) among the migrant population. The study aimed to assess the impact of the subsidising initiative on the treatment success rate (TSR) and identify the social determinants of treatment outcomes. The participants included 7072 residents and 5703 migrants who were registered in the TB Information Management System with smear-positive pulmonary TB from January 2006 to December 2010. The Cochran-Armitage test was employed to test the trends of TSR and logistic regressions to identify the factors associated with treatment outcome. Without subsidies, migrant TB cases had lower odds of successful treatment [OR = 0.20 (95% CI 0.18-0.23)] than resident cases. Subsidisation was associated with a 65% increased odds ratio of success [1.65 (1.40-1.95)] among migrant cases. The TSR has stabilised at 87% for both permanent residents and temporary migrants since 2009. Living in districts with a population density ≥20,000/km(2) was associated with a low odds ratio [0.42 (0.26-0.68)] among resident cases, whereas among migrant cases those living in districts out of central downtown had a higher odds ratio of treatment success [peripheral downtown: 1.73 (1.36-2.20), suburban: 1.69 (1.16-2.46)]. The TB cases in districts with 2.0-2.9 TB specialists/100 cases had a higher odds ratio [2.99 (1.91-4.69)] of successful treatment than cases from districts with fewer specialists. Besides free medical services, transport and living allowance subsidies to migrant patients with TB improved the treatment outcome significantly. © 2015 John Wiley & Sons Ltd.

Little is known about the associations between allergic disease, sleep-disordered breathing (SDB), and childhood nocturnal enuresis (NE). We examined whether allergic disease and SDB were associated with childhood NE. Data were assessed from the 2007-2012 Taiwan National Health Insurance Research Database. We enrolled 4308 children aged 5-18 years having NE diagnosis and age- and sex-matched 4308 children as the control group. The odds ratios of NE were calculated to determine an association with preexisting allergic disease and SDB. A total of 8616 children were included in the analysis. Prevalence of allergic diseases and SDB was significantly higher for the NE group than the control group (all p < 0.001). After adjusting odds ratios for potential confounding factors, except asthma, children with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and obstructive sleep apnea (OSA) had significantly higher odds of NE compared with children never diagnosed. With stratification for sex, girls with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, OSA, and snoring had significantly higher odds of NE, compared with girls never diagnosed. Only boys with allergic rhinitis and OSA were associated with increased odds of NE. With stratification for age, children aged 5-12 years with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and OSA had significantly higher odds of NE compared with those never diagnosed. Odds of NE increased with the number of comorbid allergic diseases. Allergic diseases and SDB are associated with increased odds of childhood NE. The odds of NE increased with the number of comorbid allergic diseases present.

Odds ratio (OR), risk ratio (RR), and prevalence ratio (PR) are some of the measures of association which are often reported in research studies quantifying the relationship between an independent variable and the outcome of interest. There has been much debate on the issue of which measure is appropriate to report depending on the study design. However, the literature on selecting a particular category of the outcome to be modeled and/or change in reference group for categorical independent variables and the effect on statistical significance, although known, is scantly discussed nor published with examples. In this article, we provide an example of a cross-sectional study wherein PR was chosen over (Prevalence) OR and demonstrate the analytic implications of the choice of category to be modeled and choice of reference level for independent variables.

Policing practices such as syringe confiscation and arrest can act as important social-structural drivers of HIV risk among people who inject drugs (PWID). However, police referral to treatment and other services may improve the health of PWID. Little is known about the role of modifiable attitudinal and knowledge factors in shaping officer behavior. Using baseline findings from a police education program (PEP), we assessed relationships between drug policy knowledge and attitudes towards public health interventions with self-reported syringe confiscation, drug arrest, and service referral among street-level police in Tijuana, Mexico. Between February, 2015 and May, 2016 we surveyed 1319 police officers who reported syringe contact. The self-administered survey focused on attitudes, knowledge, and behaviors related to drug policy, public health, and occupational safety. We used ordinal logistic regression to model the odds of syringe confiscation, arrest for heroin possession, and referring PWID to health/social programs. The sample was mostly male (87%) and had at least a high school education (80%). In the last six months, a minority reported always/sometimes confiscating syringes (49%), arresting someone for heroin possession (43%), and referring PWID to health and social programs (37%). Those reporting needlestick injuries (NSI) had 1.38 (95% CI: 1.02-1.87) higher odds of reporting syringe confiscation. Officers who had favorable views on laws that treat addiction as a public health issue had lower odds (aOR=0.78; 95% CI: 0.59-1.03) of arresting PWID. Those agreeing that it was their role to refer PWID to health and social programs had higher odds of reporting such referrals (aOR: 3.32, 95% CI: 2.52-4.37). Legal knowledge was not associated with these practices. Changing drug policy and knowledge may be insufficient in shifting police behavior. Modifying officers' occupational risks and attitudes towards harm reduction interventions can facilitate efforts to align police practices with PWID health. Copyright © 2017 Elsevier B.V.

Patients with a current acute coronary syndrome and previous ischemic heart disease, peripheral arterial disease, and/or cerebrovascular disease are reported to have a poorer outcome than those without these previous conditions. It is uncertain whether this association with outcome is observed at long-term follow-up. Prospective observational study, including 4247 patients with ST-segment elevation myocardial infarction. Detailed clinical data and information on previous ischemic heart disease, peripheral arterial disease, and cerebrovascular disease ("vascular burden") were recorded. Multivariate models were performed for in-hospital and long-term (median, 7.2 years) all-cause mortality. One vascular territory was affected in 1131 (26.6%) patients and ≥ 2 territories in 221 (5.2%). The total in-hospital mortality rate was 12.3% and the long-term incidence density was 3.5 deaths per 100 patient-years. A background of previous ischemic heart disease (odds ratio = 0.83; P = .35), peripheral arterial disease (odds ratio = 1.30; P = .34), or cerebrovascular disease (stroke) (odds ratio = 1.15; P = .59) was not independently predictive of in-hospital death. In an adjusted model, previous cerebrovascular disease and previous peripheral arterial disease were both predictors of mortality at long-term follow-up (hazard ratio = 1.57; P < .001; and hazard ratio = 1.34; P = .001; respectively). Patients with ≥ 2 diseased vascular territories showed higher long-term mortality (hazard ratio = 2.35; P < .001), but not higher in-hospital mortality (odds ratio = 1.07; P = .844). In patients with a diagnosis of ST-segment elevation acute myocardial infarction, the previous vascular burden determines greater long-term mortality. Considered individually, previous cerebrovascular disease and peripheral arterial disease were predictors of mortality at long-term after hospital discharge.

The use of ventricular assist devices has increased dramatically in adult heart failure patients. However, the overall use, outcome, comorbidities, and resource utilization of ventricular assist devices in pediatric patients have not been well described. We sought to demonstrate that the use of ventricular assist devices in pediatric patients has increased over time and that mortality has decreased. A retrospective study of the Pediatric Health Information System database was performed for patients 20 years old or younger undergoing ventricular assist device placement from 2000 to 2010. None. Four hundred seventy-five pediatric patients were implanted with ventricular assist devices during the study period: 69 in 2000-2003 (era 1), 135 in 2004-2006 (era 2), and 271 in 2007-2010 (era 3). Median age at ventricular assist device implantation was 6.0 years (interquartile range, 0.5-13.8), and the proportion of children who were 1-12 years old increased from 29% in era 1 to 47% in era 3 (p = 0.002). The majority of patients had a diagnosis of cardiomyopathy; this increased from 52% in era 1 to 72% in era 3 (p = 0.003). Comorbidities included arrhythmias (48%), pulmonary hypertension (16%), acute renal failure (34%), cerebrovascular disease (28%), and sepsis/systemic inflammatory response syndrome (34%). Two hundred forty-seven patients (52%) underwent heart transplantation and 327 (69%) survived to hospital discharge. Hospital mortality decreased from 42% in era 1 to 25% in era 3 (p = 0.004). Median hospital length of stay increased (37 d [interquartile range, 12-64 d] in era 1 vs 69 d [interquartile range, 35-130] in era 3; p < 0.001) and median adjusted hospital charges increased ($630,630 [interquartile range, $227,052-$853,318] in era 1 vs $1,577,983 [interquartile range, $874,463-$2,280,435] in era 3; p < 0.001). Factors associated with increased mortality include age less than 1 year (odds ratio, 2.04; 95% CI, 1.01-3.83), acute renal failure (odds ratio, 2.1; 95% CI, 1.26-3.65), cerebrovascular disease (odds ratio, 2.1; 95% CI, 1.25-3.62), and extracorporeal membrane oxygenation (odds ratio, 3.16; 95% CI, 1.79-5.60). Ventricular assist device placement in era 3 (odds ratio, 0.3; 95% CI, 0.15-0.57) and a diagnosis of cardiomyopathy (odds ratio, 0.5; 95% CI, 0.32-0.84), were associated with decreased mortality. Large-volume centers had lower mortality (odds ratio, 0.55; 95% CI, 0.34-0.88), lower use of extracorporeal membrane oxygenation, and higher charges. The use of ventricular assist devices and survival after ventricular assist device placement in pediatric patients have increased over time, with a concomitant increase in resource utilization. Age under 1 year, certain noncardiac morbidities, and the use of extracorporeal membrane oxygenation are associated with worse outcomes. Lower mortality was seen at larger volume ventricular assist device centers.

Iodine deficiency is the world's single most important cause of preventable mental retardation. In Ethiopia, the knowledge and perception of food handlers toward the iodized salt consumption (ISC) was very low. To assess knowledge and perception of food handlers toward consumption of iodized salt in Wolaita Sodo town and Sodo Zuria woreda, 2014. The community-based cross-sectional study design was done from May 10 to May 30, 2014 in Sodo town and Sodo Zuria woreda (district), Wolaita zone, southern Ethiopia. Systematic sampling techniques were used to identify study participants. Data entered into the software Epi Info version 3.5.3 and analyzed using the software SPSS version 16. To assess an association, odds ratio was used at 95% confidence interval, whereas confounding was controlled by employing multivariate logistic regression. Lower knowledge and perception on iodine deficiency was observed. About 239 (44.7%) of the respondents had good knowledge and 228 (42.6%) had positive attitude toward consumption of iodized salt. Most (346, 64.7%) of the participants had heard about goiter, whereas only 170 (31.8%) of them associated it with iodine deficiency. About 46.4% of respondents heard about iodized salt. Respondents' age, education, family income, place of residence, and occupation had significant association with good knowledge and positive attitude toward consumption of iodized salt. The study revealed the existence of knowledge and perception gap in iodine deficiency disorder and ISC. Household income, education of respondents, and place of residence were determinant factors for poor knowledge and perception of iodized salt. Therefore, efforts to scale-up the knowledge and perception toward ISC should focus on households with low income, educational level, and rural residence.

Knowledge of tuberculosis has been shown to influence health seeking behaviour; and urban slum dwellers are at a higher risk of acquiring tuberculosis than the general population. The study aim was to assess knowledge of tuberculosis and identify the associated socio-demographic determinants, in order to inform tailored interventions for advocacy, communication and social mobilisation in three urban-slum communities of Uganda. A cross-sectional survey of 1361 adults between April and October 2011. Data was analyzed by descriptive statistics. Adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) of potential determinants of tuberculosis (TB) knowledge were estimated by multivariable ordinal logistic regression using Stata 11.2 software. We found low knowledge of TB cause (26.7%); symptoms (46.8%), transmission (54.3%), prevention (34%) and free treatment (35%). Knowledge about TB treatment (69.4) and cure (85.1) was relatively high. Independent determinants of poor knowledge of TB in the multivariable analysis included (aOR, 95% CI) lack of formal education (0.56; 0.38 - 0.83, P = 0.004), unemployment (0.67; 0.49 - 0.90, P = 0.010) and never testing for HIV (0.69; 0.51 - 0.92, P < 0.012). Whilst, older age (1.73; 1.30 - 2.29, P < 0.001) and residing in Lira (2.02; 1.50 - 2.72, P < 0.001) were independent determinants of higher knowledge of TB. This study revealed deficiencies in the public health knowledge about TB symptoms, diagnosis and treatment among urban-slum dwellers in Uganda. Tuberculosis control programmes in similar settings should consider innovative strategies for TB education, advocacy, communication and social mobilisation to reach the youth, unemployed and less-educated; as well as those who have never tested for HIV.

Fecal incontinence (FI) is a common debilitating disorder that tends to be underreported. Although low health literacy likely contributes to the underreporting, studies on FI knowledge among the general population remain scarce. We investigated how FI knowledge is associated with attitudes and help-seeking behaviors. We conducted a cross-sectional survey among community-dwelling adults undergoing national health screening in Korea. A structured, self-administered questionnaire was used to assess FI knowledge, attitudes, and help-seeking behaviors. Odds ratios (ORs; 95% confidence intervals, CIs) were estimated using logistic regression with adjustment for covariables. Of the 601 participants completing the survey, only 29.8% were aware of the term FI, and their knowledge levels were insufficient. As for FI-related attitudes, 24.6% considered FI to be very rare, and 22.3% considered it to be moderately or less distressing. Individuals who knew the term FI tended to consider FI more common (OR: 2.45; 95%CI: 1.49-4.02) and distressing (OR: 1.68; 95%CI: 1.07-2.63) than those without knowledge. Assuming future FI occurrence, those considering FI to be distressing were less willing to ignore or self-manage the condition (OR: 0.25; 95%CI: 0.11-0.58). Among patients with FI (n = 83), only 30.1% had sought help and 8.4% had consulted doctors. Knowing the term FI was significantly associated with overall help-seeking behavior (OR: 9.23; 95%CI: 2.09-40.77). FI knowledge levels and help-seeking rates were low among community-dwelling adults. FI knowledge was significantly associated with attitudes and help-seeking behaviors. Future public education programs are warranted to improve FI knowledge, attitudes, and help-seeking behaviors. © 2018 Wiley Periodicals, Inc.

To investigate the prevalence and determinants of student and parental attitudes toward the education of children affected by HIV/AIDS in areas of rural China where AIDS is prevalent. A cross-sectional study of a random sample of students (n=732) and their parents (n=732) conducted in April 2010, using a questionnaire and in-depth interview. Twenty-six per cent of students and 29% of parents had a 'good' attitude toward the education of children affected by HIV/AIDS. Following adjustment for sociodemographic characteristics, students' attitudes were significantly associated with knowledge of HIV/AIDS non-transmission (adjusted odds ratio [aOR]= 3.13) and their parents' attitudes (aOR= 2.38), but not with knowledge of HIV/AIDS transmission, prevention or their parents' knowledge. Parents' attitudes were significantly associated with knowledge of HIV/AIDS non-transmission (aOR= 2.12) and their children's attitudes (aOR= 2.52), but not with knowledge of HIV/AIDS transmission, prevention or their children's knowledge. Stigma and discrimination undermine the right to education of HIV/AIDS-affected children in rural China. Improving non-transmission knowledge may improve caring attitudes. HIV/AIDS public health educational campaigns highlighting non-transmission and extending family education, combined with school education, may help to enhance an environment of non-discrimination and safeguard public support programs for the right to education of children affected by HIV/AIDS. © 2013 The Authors.

Registered nurses (RNs) play a pivotal role in treating pain and preventing and recognizing the adverse effects (AEs) of analgesics in patients with dementia. The purpose of this study was to determine RNs' knowledge of potentially clinically relevant AEs of analgesics. A descriptive, cross-sectional study design was used. In all, 267 RNs treating orthopedic patients, including patients with dementia, in 7 university hospitals and 10 central hospitals in Finland, completed a questionnaire. Analgesics were defined according to the Anatomic Therapeutic Classification as strong opioids, weak opioids, nonsteroidal anti-inflammatory analgesics (NSAIDs), and paracetamol. Definitions of AEs were based on the literature. Logistic regression analysis was applied to analyze which variables predicted nurses' knowledge. The RNs had a clear understanding of the AEs of paracetamol and strong opioids. However, the AEs of NSAIDs, especially renal and cardiovascular AEs, were less well known. The median percentage of correct answers was 87% when asked about strong opioids, 73% for weak opioids, and 60% for NSAIDs. Younger RNs had better knowledge of opioid-related AEs (odds ratio [OR] per 1-year increase, 0.97; 95% confidence interval [CI], 0.94-1.00) and weak opioids (OR, 0.96; 95% CI, 0.93-0.99). This study provides evidence of a deficiency in RNs' knowledge, especially regarding the adverse renal and cardiovascular effects of NSAIDs. Such lack of knowledge indicates that hospitals may need to update the knowledge of older RNs, especially those who treat vulnerable patients with dementia.

There is a growing recognition of the need to provide HIV/AIDS prevention and care to migrant workers. Social involvement, a type of social capital, is considered a 'critical enabler' of effective HIV/AIDS prevention. Designated participation in formal community groups by the government (e.g., political parties) and informal, voluntary local networks by NGOs (e.g., alumni association, cultural & sports club) play different roles in HIV prevention. The objective of this study is to assess the impact of different types of social organizations on HIV/AIDS prevention knowledge among migrant workers. A cross-sectional study of 758 migrants was conducted in Hefei, Anhui Province, China. Data were collected through a self-reported questionnaire. Logistic regression was used to assess associations between different social organizations and HIV/AIDS prevention. Migrants who participated in social organizations had a higher awareness of HIV/AIDS knowledge than migrants who do not participate in social organizations. Higher levels of HIV/AIDS knowledge is associated with positive HIV/AIDS behaviors for people who attended political parties (odds ratio [OR] = 3.49, 95% CI: 1.22-9.99). This effect is not significant for alumni association. For both political parties and alumni association members (OR = 0.19, 95% CI: 0.06-0.66, OR = 0.20, 95% CI: 0.08-0.61, respectively), people who exhibited higher levels of HIV/AIDS knowledge had more negative attitudes than those with less knowledge. Social organizations play an important role in improving HIV/AIDS knowledge and behavior in migrants, providing a great opportunity for HIV/AIDS prevention.

Objectives. We examined the relationship between children’s weight and social competence. Methods. We used data from the third- and fifth-grade waves of the nationally representative Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 (n = 8346) to examine changes in children’s weight and social competence. Results. Obesity in third grade was not associated with subsequent changes in social competence between third and fifth grade, but social competence in third grade was associated with subsequent development of obesity. Among normal-weight children, having higher social competence in third grade was associated with lower odds of becoming overweight (odds ratio [OR] = 0.80 ±0.09; P < .05) or obese (OR = 0.20 ±0.08; P < .001). In addition, obese children with higher social competence were more likely to lose weight between third and fifth grade (OR = 1.43 ±0.25; P < .05). Conclusions. Obesity and impaired social competence often occur together and have serious implications for children's well-being. More knowledge about how weight and social competence affect one another could inform interventions to promote children’s social development and reduce obesity. PMID:25393191

Military-connected youth often experience daily stressors that affect their academic success and social and emotional development. Stressors such as multiple deployments and frequent school transitions may weaken the social ties that military-connected youth have with school communities, placing them at risk of social alienation and victimization. Within this youth population, military-connected lesbian, gay, bisexual, and transgender (LGBT) youth may be especially at risk of school victimization. However, to the authors' knowledge, no empirical studies have been conducted on the school experiences of military-connected LGBT youth. Drawing from the California Healthy Kids Survey (CHKS; n = 634,978), this study explored school victimization and weapon carrying among military-connected LGBT youth and their peers. Multivariate logistic regression analyses revealed that military connection, LGB identity, and transgender identity were associated with an increased odds of nonphysical victimization, physical violence, and weapon carrying. Military transgender youth were at an increased risk of weapon carrying (adjusted odds ratio [AOR] = 1.63; 95% confidence interval [CI] = [1.23, 2.16]). Future research is needed to explore risk and protective factors influencing school victimization and weapon carrying among military-connected LGBT youth.

Objective In this study, we investigated whether physical inactivity was associated with risk of cervical cancer in women treated at an American cancer hospital. Methods This case-control study included 128 patients with cervical cancer and 512 controls matched on age. Controls were women suspected of having but not ultimately diagnosed with a neoplasm. Physical inactivity was defined in accordance with the 2008 Physical Activity Guidelines for Americans. Thus, participants reporting on average no moderate or vigorous recreational physical activity were classified as inactive. Unconditional logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CIs). Results Compared to non-cancer controls, those with cervical cancer had significantly increased odds of reporting abstinence from recreational physical activity (OR = 2.43, 95% CI: 1.56-3.80). No association was noted between occupational -related physical inactivity and cervical cancer (OR = 0.88, 95% CI: 0.58-1.36). Conclusions Our findings suggest that abstinence from regular recreational physical activity is associated with increased odds of cervical cancer. To our knowledge, this is the first US-based study examining these associations. Given the 2008 Physical Activity Guidelines for Americans, this study has identified yet another potential public health benefit to regular physical activity. Further investigation is needed using a larger sample and prospectively collected data to characterize dose of activity to mitigate risk and the optimal window of susceptibility. PMID:27105330

Empirical discussion regarding an association between koilocytosis and vulvovaginitis often occurs. Thus, the objective of this study was to assess the prevalence of microorganisms associated with bacterial vaginosis and vulvovaginitis in women with and without koilocytosis. Analytical cross-sectional study including two cohorts of women (with and without koilocytosis) who attended a cancer hospital in the city of Goiânia, state of Goiás. A total of 102 patients entered the study. The whiff test, Gram and Papanicolaou staining and bacterial and fungal culturing were performed. The results were observed using univariate analysis. The odds ratio and confidence interval (CI) of the variables were calculated; P-values < 0.05 were considered significant. The prevalence of bacterial colonization was similar in patients with and without koilocytosis. The odds ratio for candidiasis was 1.43 (CI 1.05-1.95) and the odds ratio for trichomoniasis was 1.78 (CI 1.49-2.12), in patients with koilocytosis. The prevalence of candidiasis and trichomoniasis seems to be higher in patients with koilocytosis.

The study attempts to identify predictors of injuries among persons who were hospitalized following the Armenian earthquake of 7 December 1988. A total of 189 such individuals were identified through neighbourhood polyclinics in the city of Leninakan and 159 noninjured controls were selected from the same neighbourhoods. A standardized interview questionnaire was used. Cases and controls shared many social and demographic characteristics; however, 98% of persons who were hospitalized with injuries were inside a building at the time of the earthquake, compared with 83% of the controls (odds ratio = 12.20, 95% confidence interval (CI) = 3.62-63.79). The odds ratio of injuries for individuals who were in a building that had five or more floors, compared with those in lower buildings, was 3.65 (95% CI = 2.12-6.33). Leaving buildings after the first shock of the earthquake was a protective behaviour. The odds ratio for those staying indoors compared with those who ran out was 4.40 (95% CI = 2.24-8.71).

Case-control studies to support the concept of acne cosmetica are lacking. To examine the association of post-adolescent acne with the use of cosmetics and cosmetic procedures. 910 post-adolescent patients with acne and an equal number of matched controls were studied for exposure to cosmetics and cosmetic procedures. A cumulative cosmetic exposure index was stratified into four quarters of increasing exposure. Comparison of different cumulative exposure categories with the lowest exposure category (multivariate analysis, logistic regression) showed that the odds ratios, which were always <1, progressively declined as cosmetic exposure increased [odds ratios (95% confidence intervals): 0.679 (0.501-0.922), 0.355 (0.258-0.487), 0.307 (0.217-0.433)]. However, some individual cosmetics had odds ratios >1. Overall cosmetic use was negatively associated with post-adolescent acne. The term 'acne cosmetica' is appropriate in the sense that some cosmetics may cause acne.

Our objective was to assess extrinsic influences upon childbirth. In a cohort of 1,826 days containing 17,417 childbirths among them 13,252 spontaneous labor admissions, we studied the influence of environment upon the high incidence of labor (defined by 75th percentile or higher), analyzed by logistic regression. The predictors of high labor admission included increases in outdoor temperature (odds ratio: 1.742, P = 0.045, 95%CI: 1.011 to 3.001), and decreases in atmospheric pressure (odds ratio: 1.269, P = 0.029, 95%CI: 1.055 to 1.483). In contrast, increases in tidal range were associated with a lower probability of high admission (odds ratio: 0.762, P = 0.030, 95%CI: 0.515 to 0.999). Lunar phase was not a predictor of high labor admission ( P = 0.339). Using multivariate analysis, increases in temperature and decreases in atmospheric pressure predicted high labor admission, and increases of tidal range, as a measurement of the lunar gravitational force, predicted a lower probability of high admission.

Evidence against the "booty pack": Trichomonas not associated with gonorrhea or Chlamydia.

Many Emergency Physicians armed with a positive Trichomonas wet mount will also treat for Neisseria gonorrhea (GC) and Chlamydia trachomatis (CT). This study estimates the association between Trichomonas microscopy result and a DNA test result for GC or CT. Using laboratory records from patients who had simultaneous sampling for all three infections, we calculated an odds ratio for the association between the Trichomonas result and a positive test for either GC or CT. Among 795 eligible females, 105 (13%) had Trichomonas, 74 (9%) had CT, and 35 (4%) had GC. Whereas CT and GC were strongly associated with each other (odds ratio 5.9, 95% confidence interval 2.8-12.4, p < 0.0001), Trichomonas infection was unrelated to infection with either GC or CT (odds ratio 1.1, 95% confidence interval 0.6-2, p = 0.9). Trichomonas results do not predict results for GC and CT; they should not influence the decision to treat for GC and CT.

An investigation of the olfactory function of 731 workers at a chemical facility which manufacturers acrylates and methacrylates was undertaken using a standardized quantitative test. In a cross-sectional analysis of the data, no associations of chemical exposure with olfactory test scores were observed. A nested case-control study designed to evaluate the cumulative effects of exposure on olfactory function, however, revealed elevated crude exposure odds ratios (95% confidence interval) of 2.0 (1.1, 3.8) for all workers and 6.0 (1.7, 21.5) for workers who never smoked cigarettes. Logistic regression analysis, adjusting for multiple confounders, revealed exposure odds ratios of 2.8 (1.1, 7.0) and 13.5 (2.1, 87.6) in these same groups, respectively, and a dose-response relationship between olfactory dysfunction and cumulative exposure scores--semi-quantitative indices of lifetime exposure to the acrylates. The data also revealed decreasing exposure odds ratios with increasing duration since last exposure to these chemicals, suggesting that the effects may be reversible. PMID:2784947

Back disorders and health problems among subway train operators exposed to whole-body vibration.

Johanning, E

1991-12-01

Back disease associated with whole-body vibration has not been evaluated for subway train operators. A recent study demonstrated that this group is exposed to whole-body vibration at levels above the international standard. To investigate this risk further, a self-administered questionnaire survey was conducted among subway train operators (N = 492) and a similar reference group (N = 92). The operators had a higher prevalence than the referents in all aspects of back problems, particularly for cervical and lower back pain. In a multiple logistic regression model, the odds ratio for sciatic pain among subway train operators was 3.9 (95% CI 1.7-8.6); the operators also had a higher risk of hearing-related problems (odds ratio 3.2, 95% CI 0.6-17.4) and of gastrointestinal problems (odds ratio 1.6, 95% CI 1.1-2.5). Although a cumulative dose-response relationship could not be statistically demonstrated, the findings appear to be related to exposure to whole-body vibration and inadequate ergonomic conditions.

Background Health risks of using styrene to manufacture windblades for the green energy sector are unknown. Methods Using data collected from 355 (73%) current windblade workers and regression analysis, we investigated associations between health outcomes and styrene exposure estimates derived from urinary styrene metabolites. Results The median current styrene exposure was 53.6 mg/g creatinine (interquartile range: 19.5–94.4). Color blindness in men and women (standardized morbidity ratios 2.3 and 16.6, respectively) was not associated with exposure estimates, but was the type previously reported with styrene. Visual contrast sensitivity decreased and chest tightness increased (odds ratio 2.9) with increasing current exposure. Decreases in spirometric parameters and FeNO, and increases in the odds of wheeze and asthma-like symptoms (odds ratios 1.3 and 1.2, respectively) occurred with increasing cumulative exposure. Conclusions Despite styrene exposures below the recommended 400 mg/g creatinine, visual and respiratory effects indicate the need for additional preventative measures in this industry. PMID:26305283

Little published information is available about access failure in children undergoing chronic peritoneal dialysis. Our objectives were to evaluate frequency, risk factors, interventions, and outcome of peritoneal dialysis access revision. Data were derived from 824 incident and 1629 prevalent patients from 105 pediatric nephrology centers enrolled in the International Pediatric Peritoneal Dialysis Network Registry between 2007 and 2015. In total, 452 access revisions were recorded in 321 (13%) of 2453 patients over 3134 patient-years of follow-up, resulting in an overall access revision rate of 0.14 per treatment year. Among 824 incident patients, 186 (22.6%) underwent 188 access revisions over 1066 patient-years, yielding an access revision rate of 0.17 per treatment year; 83% of access revisions in incident patients were reported within the first year of peritoneal dialysis treatment. Catheter survival rates in incident patients were 84%, 80%, 77%, and 73% at 12, 24, 36, and 48 months, respectively. By multivariate logistic regression analysis, risk of access revision was associated with younger age (odds ratio, 0.93; 95% confidence interval, 0.92 to 0.95; P<0.001), diagnosis of congenital anomalies of the kidney and urinary tract (odds ratio, 1.28; 95% confidence interval, 1.03 to 1.59; P=0.02), coexisting ostomies (odds ratio, 1.42; 95% confidence interval, 1.07 to 1.87; P=0.01), presence of swan neck tunnel with curled intraperitoneal portion (odds ratio, 1.30; 95% confidence interval, 1.04 to 1.63; P=0.02), and high gross national income (odds ratio, 1.10; 95% confidence interval, 1.02 to 1.19; P=0.01). Main reasons for access revisions included mechanical malfunction (60%), peritonitis (16%), exit site infection (12%), and leakage (6%). Need for access revision increased the risk of peritoneal dialysis technique failure or death (hazard ratio, 1.35; 95% confidence interval, 1.10 to 1.65; P=0.003). Access dysfunction due to mechanical causes doubled the risk of technique failure compared with infectious causes (hazard ratio, 1.95; 95% confidence interval, 1.20 to 2.30; P=0.03). Peritoneal dialysis catheter revisions are common in pediatric patients on peritoneal dialysis and complicate provision of chronic peritoneal dialysis. Attention to potentially modifiable risk factors by pediatric nephrologists and pediatric surgeons should be encouraged. Copyright © 2016 by the American Society of Nephrology.

Self-expandable metal stents (SEMS) are used for palliating inoperable malignant biliary strictures. It is unclear if covered metal stents are superior to uncovered metal stents in these patients. We compared clinical outcomes in patients with covered and uncovered stents. Studies using covered and uncovered metallic stents for palliation in patients with malignant biliary stricture were reviewed. Articles were searched in MEDLINE, PubMed, and Ovid journals. Fixed and random effects models were used to calculate the pooled proportions. Initial search identified 1436 reference articles, of which 132 were selected and reviewed. Thirteen studies (n = 2239) for covered and uncovered metallic stents which met the inclusion criteria were included in this analysis. Odds ratio for stent occlusion rates in covered vs. uncovered stents was 0.79 (95 % CI = 0.65 to 0.96). Survival benefit in patients with covered vs. uncovered stents showed the odds ratio to be 1.29 (95 % CI = 0.95 to 1.74). Pooled odds ratio for migration of covered vs. uncovered stents was 9.9 (95 % CI = 4.5 to 22.3). Covered stents seemed to have significantly lesser occlusion rates, increased odds of migration, and increased odds of pancreatitis compared to uncovered stents. There was no statistically significant difference in the survival benefit, overall adverse event rate, and patency period of covered vs. uncovered metal stents in patients with malignant biliary strictures.

Background While most individuals wish to die at home, the reality is that most will die in hospital. Aim To determine whether receiving a physician home visit near the end-of-life is associated with lower odds of death in a hospital. Design Observational retrospective cohort study, examining location of death and health care in the last year of life. Setting/Participants Population-level study of Ontarians, a Canadian province with over 13 million residents. All decedents from April 1, 2010 to March 31, 2013 (n = 264,754) Results More than half of 264,754 decedents died in hospital: 45.7% died in an acute care hospital and 7.7% in complex continuing care. After adjustment for multiple factors–including patient illness, home care services, and days of being at home–receiving at least one physician home visit from a non-palliative care physician was associated with a 47% decreased odds (odds-ratio, 0.53; 95%CI: 0.51–0.55) of dying in a hospital. When a palliative care physician specialist was involved, the overall odds declined by 59% (odds ratio, 0.41; 95%CI: 0.39–0.43). The same model, adjusting for physician home visits, showed that receiving palliative home care was associated with a similar reduction (odds ratio, 0.49; 95%CI: 0.47–0.51). Conclusion Location of death is strongly associated with end-of-life health care in the home. Less than one-third of the population, however, received end-of-life home care or a physician visit in their last year of life, revealing large room for improvement. PMID:29447291

Laparoscopic sleeve gastrectomy (LSG) has become popular due to its technical ease and excellent short-term results. Understanding the risk profile of LSG compared with the gold standard laparoscopic Roux-en-Y gastric bypass (LRYGB) is critical for patient selection. To use traditional regression techniques and random forest classification algorithms to compare LSG with LRYGB using the 2015 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Data Registry. United States. Outcomes were leak, morbidity, and mortality within 30 days. Variable importance was assessed using random forest algorithms. Multivariate models were created in a training set and evaluated on the testing set with receiver operating characteristic curves. The adjusted odds of each outcome were compared. Of 134,142 patients, 93,062 (69%) underwent LSG and 41,080 (31%) underwent LRYGB. One hundred seventy-eight deaths occurred in 96 (.1%) of LSG patients compared with 82 (.2%) of LRYGB patients (P<.001). Morbidity occurred in 8% (5.8% in LSG versus 11.7% in LRYGB, P<.001). Leaks occurred in 1% (.8% in LSG versus 1.6% in LRYGB, P<.001). The most important predictors of all outcomes were body mass index, albumin, and age. In the adjusted multivariate models, LRYGB had higher odds of all complications (leak: odds ratio 2.10, P<.001; morbidity: odds ratio 2.02, P<.001; death: odds ratio 1.64, P<.01). In the Metabolic and Bariatric Surgery Accreditation and Quality Improvements data registry for 2015, LSG had half the risk-adjusted odds of death, serious morbidity, and leak in the first 30 days compared with LRYGB.

There have been longstanding concerns over Malawian doctors migrating to high-income countries. Early career is a particularly vulnerable period. After significant policy changes, we examined the retention of recent medical graduates within Malawi and the public sector. We obtained data on graduates between 2006 and 2012 from the University of Malawi College of Medicine and Malawi Ministry of Health. We utilised the alumni network to triangulate official data and contacted graduates directly for missing or uncertain data. Odds ratios and chi-squared tests were employed to investigate relationships by graduation year and gender. We traced 256 graduates, with complete information for more than 90%. Nearly 80% of registered doctors were in Malawi (141/178, 79.2%), although the odds of emigration doubled with each year after graduation (odds ratio = 1.98, 95% CI = 1.54-2.56, P < 0.0001). Of the 37 graduates outside Malawi (14.5%), 23 (62.2%) were training in South Africa under a College of Medicine sandwich programme. More than 80% of graduates were working in the public sector (185/218, 82.6%), with the odds declining by 27% for each year after graduation (odds ratio = 0.73, 95% CI = 0.61-0.86, P < 0.0001). While most doctors remain in Malawi and the public sector during their early careers, the odds of leaving both increase with time. The majority of graduates outside Malawi are training in South Africa under visa restrictions, reflecting the positive impact of postgraduate training in Malawi. Concerns over attrition from the public sector are valid and require further exploratory work. © 2014 The Authors. Tropical Medicine & International Health Published by John Wiley & Sons Ltd.

To study the association between parents' labour market participation and children's health and wellbeing. Parent reported data on health and wellbeing among their children from the survey Health and welfare among children and adolescents in the Nordic countries, 1996. A cross sectional study of random samples of children and their families in five Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden). A total of 10 317 children aged 2-17 years. Children in families with no parents employed in the past six months had higher prevalence of recurrent psychosomatic symptoms (odds ratio 1.67, 95% confidence intervals 1.16 to 2.40), chronic illness (odds ratio 1.35, 95% confidence intervals 1.00 to 1.84), and low wellbeing (odds ratio 1.47, 95% confidence intervals 1.12 to 1.94). Social class, family type, parents' immigrant status, gender and age of the child, respondent, and country were included as confounders. When social class, family type and the parents' immigrant status (one or more born in the Nordic country versus both born elsewhere) were introduced into the model, the odds ratios were reduced but were still statistically significant. Health outcomes and parents' labour market participation were associated in all five countries. Children in families with no parents employed in the past six months had higher prevalence of ill health and low wellbeing in the five Nordic countries despite differences in employment rates and social benefits.

Our aim was to ascertain the incidence of, reasons for, and risk factors associated with hospital readmission after an operation for benign distal esophageal disease. Using the American College of Surgeons National Surgical Quality Improvement Program database (2012-2014), patients with a primary diagnosis of gastroesophageal reflux disease, paraesophageal hiatal hernia, or achalasia who underwent fundoplication, paraesophageal hernia repair, or Heller myotomy were identified. The primary outcome was hospital readmission. Multivariable logistic regression analysis was used to identify risk factors associated with hospital readmission. Of the 14,478 patients included in this study, 801 (5.5%) were readmitted at a median of 11 days (interquartile range 6-17) postprocedure. Intolerance of oral intake (21.8%), respiratory complications (11.6%), abdominal pain (6.0%), and venous thromboembolic events (4.7%) were some of the most common reasons for readmission. Open operative approach (odds ratio 1.34, 95% confidence interval 1.05-1.71), chronic steroid use (odds ratio 1.48, 95% confidence interval 1.10-2.00), emergency admission (odds ratio 1.50, 95% confidence interval 1.01-2.21), and predischarge complication (odds ratio 1.91, 95% confidence interval 1.42-2.59) were associated most strongly with hospital readmission. Implementing standardized perioperative strategies, such as nutritional counseling, early ambulation, intensive pulmonary toilet, and deep vein thrombosis prophylaxis, may help decrease the number of preventable readmissions and enhance the overall quality of care in this patient population.
