We sought to characterize predictors of neonatal outcome in women with severe preeclampsia or eclampsia who were delivered of their infants preterm. We performed a retrospective analysis of 195 pregnancies delivered between 24 and 33 weeks' gestation because of severe preeclampsia or eclampsia. Multiple logistic regression and univariate chi(2) analysis were performed for the dependent outcome variables of survival and respiratory distress syndrome by use of independent fetal and maternal variables. A P value of <.05 was considered significant. In the multivariate analysis, respiratory distress syndrome was inversely related to gestational age at delivery (P =.0018) and directly related to cesarean delivery (P =.02), whereas survival was directly related to birth weight (P =.00025). There was no correlation in the multivariate analysis between respiratory distress syndrome or survival and corticosteroid use, composite neonatal morbidity, mean arterial pressure, eclampsia, or abruptio placentae. In the univariate analysis respiratory distress syndrome was associated with cesarean delivery (odds ratio, 7.19; 95% confidence interval, 2. 91-18.32). The incidence of intrauterine growth restriction increased as gestational age advanced. Furthermore, intrauterine growth restriction decreased survival in both the multivariate (P =. 038; odds ratio, 13.2; 95% confidence interval, 1.16-151.8) and univariate (P =.001; odds ratio, 5.88; 95% confidence interval, 1. 81-19.26) analyses. The presence of intrauterine growth restriction adversely affected survival independently of other variables. Presumed intrauterine stress, as reflected by the severity of maternal disease, did not improve neonatal outcome.

To investigate whether the risk of motorcycle crash related injuries is associated with the conspicuity of the driver or vehicle. Population based case-control study. Auckland region of New Zealand from February 1993 to February 1996. 463 motorcycle drivers (cases) involved in crashes leading to hospital treatment or death; 1233 motorcycle drivers (controls) recruited from randomly selected roadside survey sites. Estimates of relative risk of motorcycle crash related injury and population attributable risk associated with conspicuity measures, including the use of reflective or fluorescent clothing, headlight operation, and colour of helmet, clothing, and motorcycle. Crash related injuries occurred mainly in urban zones with 50 km/h speed limit (66%), during the day (63%), and in fine weather (72%). After adjustment for potential confounders, drivers wearing any reflective or fluorescent clothing had a 37% lower risk (multivariate odds ratio 0.63, 95% confidence interval 0.42 to 0.94) than other drivers. Compared with wearing a black helmet, use of a white helmet was associated with a 24% lower risk (multivariate odds ratio 0.76, 0.57 to 0.99). Self reported light coloured helmet versus dark coloured helmet was associated with a 19% lower risk. Three quarters of motorcycle riders had their headlight turned on during the day, and this was associated with a 27% lower risk (multivariate odds ratio 0.73, 0.53 to 1.00). No association occurred between risk and the frontal colour of drivers' clothing or motorcycle. If these odds ratios are unconfounded, the population attributable risks are 33% for wearing no reflective or fluorescent clothing, 18% for a non-white helmet, 11% for a dark coloured helmet, and 7% for no daytime headlight operation. Low conspicuity may increase the risk of motorcycle crash related injury. Increasing the use of reflective or fluorescent clothing, white or light coloured helmets, and daytime headlights are simple, cheap interventions that could considerably reduce motorcycle crash related injury and death.

Mannitol is often used to reduce cerebral edema in acute intracerebral hemorrhage but without strong supporting evidence of benefit. We aimed to determine the impact of mannitol on outcome among participants of the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2). INTERACT2 was an international, open, blinded end point, randomized controlled trial of 2839 patients with spontaneous intracerebral hemorrhage (<6 hours) and elevated systolic blood pressure allocated to intensive (target systolic blood pressure, <140 mm Hg within 1 hour) or guideline-recommended (target systolic blood pressure, <180 mm Hg) blood pressure-lowering treatment. Propensity score and multivariable analyses were performed to investigate the relationship between mannitol treatment (within 7 days) and poor outcome, defined by death or major disability on the modified Rankin Scale score (3-6) at 90 days. There was no significant difference in poor outcome between mannitol (n=1533) and nonmannitol (n=993) groups: propensity score-matched odds ratio of 0.90 (95% confidence interval, 0.75-1.09; P=0.30) and multivariable odds ratio of 0.87 (95% confidence interval, 0.71-1.07; P=0.18). Although a better outcome was suggested in patients with larger (≥15 mL) than those with smaller (<15 mL) baseline hematomas who received mannitol (odds ratio, 0.52 [95% confidence interval, 0.35-0.78] versus odds ratio, 0.91 [95% confidence interval, 0.72-1.15]; P homogeneity<0.03 in propensity score analyses), the association was not consistent in analyses across other cutoff points (≥10 and ≥20 mL) and for differing grades of neurological severity. Mannitol was not associated with excess serious adverse events. Mannitol seems safe but might not improve outcome in patients with acute intracerebral hemorrhage. URL: http://www.clinicaltrials.gov.

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.

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.

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.

We aimed to examine whether there is a correlation between the health recovery of industrial accident victims and their perceived socioeconomic status. Data were obtained from the first Panel Study of Worker's Compensation Insurance, which included 2,000 participants. We performed multivariate regression analysis and determined the odds ratios for participants with a subjectively lower socioeconomic status and for those with a subjectively lower middle socioeconomic status using 95% confidence intervals. An additional multivariate regression analysis yielded the odds ratios for participants with a subjectively lower socioeconomic status and those with a subjectively upper middle socioeconomic class using 95% confidence intervals. Of all participants, 299 reported a full recovery, whereas 1,701 did not. We examined the odds ratio (95% confidence intervals) for participants' health recovery according to their subjective socioeconomic status while controlling for sex, age, education, tobacco use, alcohol use, subjective state of health prior to the accident, chronic disease, employment duration, recovery period, accident type, disability status, disability rating, and economic participation. The odds of recovery in participants with a subjectively lower middle socioeconomic status were 1.707 times greater (1.264-2.305) than that of those with a subjectively lower socioeconomic status. Similarly, the odds of recovery in participants with a subjectively upper middle socioeconomic status were 3.124 times greater (1.795-5.438) than that of those with a subjectively lower socioeconomic status. Our findings indicate that participants' perceived socioeconomic disparities extend to disparities in their health status. The reinforcement of welfare measures is greatly needed to temper these disparities.

Emergency general surgery during hospitalization has not been well characterized. We examined emergency operations remote from admission to identify predictors of postoperative 30-day mortality, postoperative duration of stay >30 days, and complications. Patients >18 years in The American College of Surgeons National Surgical Quality Improvement Program (2011-2014) who had 1 of 7 emergency operations between hospital day 3-18 were included. Patients with operations >95th percentile after admission (>18 days; n = 581) were excluded. Exploratory laparotomy only (with no secondary procedure) represented either nontherapeutic or decompressive laparotomy. Multivariable logistic regression was used to identify predictors of study outcomes. Of 10,093 patients with emergency operations, most were elderly (median 66 years old [interquartile ratio: 53-77 years]), white, and female. Postoperative 30-day mortality was 12.6% (n = 1,275). Almost half the cohort (40.1%) had a complication. A small subset (6.8%) had postoperative duration of stay >30 days. Postoperative mortality after exploratory laparotomy only was particularly high (>40%). In multivariable analysis, an operation on hospital day 11-18 compared with day 3-6 was associated with death (odds ratio 1.6 [1.3-2.0]), postoperative duration of stay >30 days (odds ratio 2.0 [1.6-2.6]), and complications (odds ratio 1.5 [1.3-1.8]). Exploratory laparotomy only also was associated with death (odds ratio 5.4 [2.8-10.4]). Emergency general surgery performed during a hospitalization is associated with high morbidity and mortality. A longer hospital course before an emergency operation is a predictor of poor outcomes, as is undergoing exploratory laparotomy only. Copyright © 2017 Elsevier Inc. All rights reserved.

Child enrollment in Medicaid managed care (MMC) has expanded dramatically, primarily through state mandates. Care coordination is a key metric in MMC evaluation because it drives much of the proposed cost savings and may be associated with improved health outcomes and utilization. We evaluated the relationships between enrollment in 2 MMC structures, primary care case management (PCCM) and health maintenance organization (HMO) and access to and receipt of care coordination by children. Using data from the 2011/2012 National Survey of Children's Health and the Medicaid Statistical Information System state data mart, we conducted a retrospective, cross-sectional analysis of the relationships between fee-for-service, PCCM or HMO enrollment, and access to and receipt of care coordination. State-level univariate analyses and individual and state multilevel multivariable analyses evaluated correlations between MMC enrollment and care coordination, controlling for demographic characteristics and state financing levels. In univariate and multilevel multivariable analyses, the PCCM penetration rate was significantly associated with increased access to care coordination (adjusted odds ratio: 1.23, P = .034) and receipt of care coordination (adjusted odds ratio: 1.37, P = .02). The HMO penetration rate was significantly associated with lower access to care coordination (adjusted odds ratio: 0.85, P = .05) and receipt of care coordination (adjusted odds ratio: 0.71, P < .001). Fee-for-service served as the referent. State utilization of MMC varied widely. These data suggest that care coordination may be more effective in PCCM than HMO structures. States should consider care coordination outcomes when structuring their Medicaid programs. Copyright © 2017 by the American Academy of Pediatrics.

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

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.

Purpose To evaluate the association between incidence of any kidney cancer and type 2 diabetes mellitus. Methods A random sample of 1,000,000 subjects covered by the National Health Insurance was recruited. A total of 998728 people (115655 diabetes and 883073 non-diabetes) without kidney cancer at recruitment were followed from 2003 to 2005. The cumulative incidence of kidney cancer from 2003 to 2005 in diabetic patients and non-diabetic people in all ages and in age <40, 40–64, 65–74 and ≥75 years were calculated in the diabetic patients and the non-diabetic people, respectively. Logistic regression was used to estimate the odds ratios comparing diabetic patients to non-diabetic people in the respective age groups. Multivariable-adjusted odds ratios for kidney cancer with regards to diabetes status and diabetes duration (as a continuous variable or categorized into subgroups of non-diabetes, diabetes duration <1 year, 1–2.9 years, 3–4.9 years and ≥5 years) were estimated after multivariable adjustment. The multivariable-adjusted odds ratios for all baseline variables were also estimated for diabetic patients and non-diabetic people, respectively. Results The 3-year cumulative incidence of kidney cancer in the diabetic patients and the non-diabetic people was 166.9 and 33.1 per 100,000 person-years, respectively. The incidence increased with regards to increasing age in both the diabetic patients and the non-diabetic people, but a higher risk of kidney cancer for the diabetic patients compared to the non-diabetic people was consistently observed in different age groups. After multivariable adjustment, the odds ratio for diabetic patients versus non-diabetic people was 1.7 (95% confidence interval: 1.3–2.1, P<0.01). While compared to the non-diabetic people, the odds ratio (95% confidence interval) for diabetes duration <1, 1–2.9 years, 3–4.9 years and ≥5 years was 1.5 (0.8–2.7), 1.6 (1.0–2.4), 1.6 (1.1–2.4) and 1.7 (1.3–2.3), respectively (P-trend <0.01). Analyses conducted in the diabetic patients and the non-diabetic people, respectively, consistently showed age, nephropathy and end-stage renal disease as significant risk factors of kidney cancer. Additionally, living in metropolitan Taipei region might also be associated with a higher risk of kidney cancer in the non-diabetic people, indicating a potential link between kidney cancer and some factors related to urbanization. Conclusions Patients with type 2 diabetes mellitus have a significantly higher risk of kidney cancer. PMID:26559055

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.

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 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.

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.

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.

To estimate the prevalence of, and risk factors associated with, sexual dysfunction among Hong Kong Chinese married men aged 30-60 years. The present study was a part of the Ninth Knowledge, Attitude, and Practice survey conducted in 2007 by the Family Planning Association of Hong Kong. The data set consisted of 728 face-to-face interviews with Hong Kong Chinese married men aged 30-60 years living in the community. The classification of sexual dysfunction in the "Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition" was used to measure male sexual dysfunction (MSD). Regarding MSD prevalence, approximately 15% of men reported ≥ 1 form of MSD, with a lack of sexual interest, erectile dysfunction, and premature ejaculation present in 11.1%, 4.3%, and 4.7%, respectively. Multivariate analysis showed that age (odds ratio 2.39), employment status (odds ratio 3.62), having a wife who sought medical help for sexual problems (odds ratio 4.47), liberal attitudes toward female sexual initiation (odds ratio 2.07), and marital dissatisfaction (odds ratio 2.35) were all statistically significant risk factors for MSD and its specific components among the sample. However, having traditional attitudes toward female sexual refusal was a protective factor for MSD (odds ratio 0.51) and lack of sexual interest (odds ratio 0.51). The prevalence of MSD was low among young and middle-age married men in Hong Kong. Factors contributing to the risk of MSD spanned the domains of socioeconomic status, attitudes toward sex, and relationship factors. These findings suggest future directions for public health policies and the delivery of services that address the prevention and treatment of MSD. Copyright © 2013 Elsevier Inc. All rights reserved.

Intermittent and daily smokers: two different socioeconomic patterns, and diverging influence of social participation

PubMed Central

Lindstrom, M.; Ostergren, P.

2001-01-01

OBJECTIVE—To investigate socioeconomic differences in intermittent and daily smoking, and to assess the association between social participation and these two smoking behaviours.
DESIGN/SETTING/PARTICIPANTS/MEASUREMENTS—A population of 11 837 individuals interviewed in 1992-94, aged 45-64 years, was investigated in this cross sectional study. A multivariate logistic regression model was used to assess socioeconomic differences in daily and intermittent smoking, adjusting for age, country of origin, previous/current diseases, and marital status. Finally, social participation as a measure of social capital was introduced in the multivariate model.
RESULTS—When unskilled manual workers were compared to high level non-manual employees, odds ratios of 2.3 (95% confidence interval (CI) 1.7 to 3.0) for men and 1.9 (95% CI 1.4 to 2.5) for women were found in regard to daily smoking, but odd ratios of only 0.7 (95% CI 0.4 to 1.2) for men and 1.3 (95% CI 0.7 to 2.4) for women were found in regard to intermittent smoking. A decrease in the daily smoking odds ratios was found when social participation was introduced in the model, while the odds ratios regarding intermittent smoking were unaffected.
CONCLUSIONS—There were no socioeconomic differences in intermittent smoking and no association with social participation, a result that contrasts sharply with the patterns of daily smoking. These findings have important implications for the discussion concerning social capital and preventive measures.

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.

Statistical models predicting cancer recurrence after surgery are based on biologic variables. We have shown previously that prostate cancer recurrence is related to both tumor biology and to surgical technique. Here, we evaluate the association between several biological predictors and biochemical recurrence across varying surgical experience. The study included two separate cohorts: 6,091 patients treated by open radical prostatectomy and an independent replication set of 2,298 patients treated laparoscopically. We calculated the odds ratios for biological predictors of biochemical recurrence-stage, Gleason grade and prostate-specific antigen (PSA)-and also the predictive accuracy (area under the curve, AUC) of a multivariable model, for subgroups of patients defined by the experience of their surgeon. In the open cohort, the odds ratio for Gleason score 8+ and advanced pathologic stage, though not PSA or Gleason score 7, increased dramatically when patients treated by surgeons with lower levels of experience were excluded (Gleason 8+: odds ratios 5.6 overall vs. 13.0 for patients treated by surgeons with 1,000+ prior cases; locally advanced disease: odds ratios of 6.6 vs. 12.2, respectively). The AUC of the multivariable model was 0.750 for patients treated by surgeons with 50 or fewer cases compared to 0.849 for patients treated by surgeons with 500 or more. Although predictiveness was lower overall for the independent replication set cohort, the main findings were replicated. Surgery confounds biology. Although our findings have no direct clinical implications, studies investigating biological variables as predictors of outcome after curative resection of cancer should consider the impact of surgeon-specific factors.

The aim of our study is to investigate the prevalence of silent pulmonary embolism in patients with deep venous thrombosis in the lower limbs and to evaluate the associated risk factors. A total of 322 patients with acute deep venous thrombosis confirmed by CT venography or Doppler ultrasonography were studied. The diagnosis of silent pulmonary embolism was established by computed tomography pulmonary arteriography (CTPA). The association between covariates and the prevalence of silent pulmonary embolism in patients with deep venous thrombosis in lower limbs were assessed using chi-square test and multivariable regression. The incidence of silent pulmonary embolism was 33.5% (108 in 322 patients) in all patients with deep venous thrombosis in lower limbs. Chi-square test showed male gender, the right lower limb, proximal location of the thrombus, unprovoked venous thrombosis and coexisting heart diseases were related to a higher incidence of silent pulmonary embolism in patients with deep venous thrombosis in lower limbs. The multivariate regression analysis confirmed that the risk factors associated with silent pulmonary embolism in deep venous thrombosis patients included the right side and proximal location of the thrombus (odds ratio: 2.023, 95% CI: 1.215-3.368; odds ratio: 3.610, 95% CI: 1.772-7.354), unprovoked venous thrombosis (odds ratio: 2.037, 95% CI: 1.188-3.493), coexisting heart diseases (odds ratio: 4.507, 95% CI: 2.667-7.618). Silent pulmonary embolism occurred frequently in patients with deep venous thrombosis in lower limbs. The right side, the proximal location of the thrombus, unprovoked venous thrombosis and coexisting heart diseases increased the risk for the occurrence of silent pulmonary embolism. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Heterotopic ossification (HO) is a debilitating complication of burn injury; however, incidence and risk factors are poorly understood. In this study, we use a multicenter database of adults with burn injuries to identify and analyze clinical factors that predict HO formation. Data from six high-volume burn centers, in the Burn Injury Model System Database, were analyzed. Univariate logistic regression models were used for model selection. Cluster-adjusted multivariate logistic regression was then used to evaluate the relationship between clinical and demographic data and the development of HO. Of 2,979 patients in the database with information on HO that addressed risk factors for development of HO, 98 (3.5%) developed HO. Of these 98 patients, 97 had arm burns, and 96 had arm grafts. When controlling for age and sex in a multivariate model, patients with greater than 30% total body surface area burn had 11.5 times higher odds of developing HO (p < 0.001), and those with arm burns that required skin grafting had 96.4 times higher odds of developing HO (p = 0.04). For each additional time a patient went to the operating room, odds of HO increased by 30% (odds ratio, 1.32; p < 0.001), and each additional ventilator day increased odds by 3.5% (odds ratio, 1.035; p < 0.001). Joint contracture, inhalation injury, and bone exposure did not significantly increase odds of HO. Risk factors for HO development include greater than 30% total body surface area burn, arm burns, arm grafts, ventilator days, and number of trips to the operating room. Future studies can use these results to identify highest-risk patients to guide deployment of prophylactic and experimental treatments. Prognostic study, level III.

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.

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.

Methods The Vascular Quality Initiative thoracic endovascular aortic repair module (April 2011-July 2014) was analyzed. Patients undergoing left subclavian artery coverage were divided into two groups according to revascularization status. The association between left subclavian artery revascularization with the primary outcome of spinal cord ischemia and the secondary outcome of stroke was assessed with multivariable analysis adjusting for between-group baseline differences. Results The left subclavian artery was covered in 508 (24.6%) of the 2063 thoracic endovascular aortic repairs performed. Among patients with left subclavian artery coverage, 58.9% underwent revascularization. Spinal cord ischemia incidence was 12.1% in the group without revascularization compared to 8.5% in the group undergoing left subclavian artery revascularization (odds ratio (95%CI): 1.48(0.82-2.68), P = 0.189). Multivariable analysis adjustment identified an independent association between left subclavian artery coverage without revascularization and the incidence of spinal cord ischemia (adjusted odds ratio (95%CI): 2.29(1.03-5.14), P = 0.043). Although the incidence of stroke was also higher for the group with a covered and nonrevascularized left subclavian artery (12.1% versus 8.5%), this difference was not statistically significant after multivariable analysis (adjusted odds ratio (95%CI): 1.55(0.74-3.26), P = 0.244). Conclusion For patients undergoing left subclavian artery coverage during thoracic endovascular aortic repair, the addition of a revascularization procedure was associated with a significantly lower incidence of spinal cord ischemia.

This study aimed to determine which children with suspected appendicitis should be considered for a computerized tomography (CT) scan after a non-diagnostic ultrasound (US) in the Emergency Department (ED). We retrospectively reviewed patients 0-18year old, who presented to the ED with complaints of abdominal pain, during 2011-2015 and while in the hospital had both US and CT. We recorded demographic and clinical data and outcomes, and used univariate and multivariate methods for comparing patients who did and didn't have appendicitis on CT after non-diagnostic US. Multivariate analysis was performed using logistic regression to determine what variables were independently associated with appendicitis. A total of 328 patients were enrolled, 257 with non-diagnostic US (CT: 82 had appendicitis, 175 no-appendicitis). Younger children and those who reported vomiting or had right lower abdominal quadrant (RLQ) tenderness, peritoneal signs or White Blood Cell (WBC) count >10,000 in mm 3 were more likely to have appendicitis on CT. RLQ tenderness (Odds Ratio: 2.84, 95%CI: 1.07-7.53), peritoneal signs (Odds Ratio: 11.37, 95%CI: 5.08-25.47) and WBC count >10,000 in mm 3 (Odds Ratio: 21.88, 95%CI: 7.95-60.21) remained significant after multivariate analysis. Considering CT with 2 or 3 of these predictors would have resulted in sensitivity of 94%, specificity of 67%, positive predictive value of 57% and negative predictive value of 96% for appendicitis. Ordering CT should be considered after non-diagnostic US for appendicitis only when children meet at least 2 predictors of RLQ tenderness, peritoneal signs and WBC>10,000 in mm 3 .

To analyze the prognostic influence of metastatic pattern (MP) compared with other biologic and clinical factors in stage IV breast cancer at initial diagnosis (BCID) and evaluate factors associated with specific sites of metastases (SSM). We evaluated women with stage IV BCID with known metastatic sites, reported to the Surveillance, Epidemiology and End Results program from 2010 to 2013. MP was categorized as bone-only, visceral, bone and visceral (BV), and other. Univariate and multivariate analyses determined the effects of each variable on overall survival (OS). Logistic regression examined factors associated with SSM. We included 9143 patients. Bone represented 37.5% of patients, visceral 21.9%, BV 28.8%, and other 11.9%. Median OS by MP was as follows: bone 38 months, visceral 21 months, BV 19 months, and other 33 months (P < 0.0001). Univariate analysis showed that higher number of metastatic sites had worse prognosis. In multivariate analysis, older age (hazard ratio 1.9), black race (hazard ratio 1.17), grade 3/4 tumors (hazard ratio 1.6), triple-negative (hazard ratio 2.24), BV MP (hazard ratio 2.07), and unmarried patients (hazard ratio 1.25) had significantly shorter OS. As compared with HR+/HER2- tumors, triple-negative and HR-/HER2+ had higher odds of brain, liver, lung, and other metastases. HR+/HER2+ had higher odds of liver metastases. All three subtypes had lower odds of bone metastases. There were substantial differences in OS according to MP. Tumor subtypes have a clear influence among other factors on SSM. We identified several prognostic factors that could guide therapy selection in treatment naïve patients.

This study was aimed to examine the cross-sectional association of protein, carbohydrate, and fat intake with depressive symptoms among 1794 Japanese male workers aged 18-69 years who participated in a health survey. Dietary intake was assessed with a validated self-administered diet history questionnaire. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) scale. Odds ratio of depressive symptoms (CES-D scale of ≥16) was estimated by using multiple logistic regression with adjustment for covariates including folate, vitamin B6, vitamin B12, polyunsaturated fatty acid, magnesium, and iron intake. Multivariable-adjusted odds ratio of depressive symptoms for the highest quartile of protein intake was 26%, albeit not statistically significant, lower compared with the lowest. The inverse association was more evident when a cutoff value of CES-D score ≥19 was used. The multivariable-adjusted odds ratios (95% confidence intervals) for the highest through lowest quartile of protein intake were 1.00 (reference), 0.69 (0.47-1.01), 0.69 (0.44-1.09), and 0.58 (0.31-1.06) (P for trend=0.096). Neither carbohydrate nor fat intake was associated with depressive symptoms. Our findings suggest that low protein intake may be associated with higher prevalence of depressive symptoms in Japanese male workers. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Little is known about folate and atopy or severe asthma exacerbations. We examined whether folate deficiency is associated with number of positive skin tests to allergens or severe asthma exacerbations in a high-risk population and further assessed whether such association is explained or modified by vitamin D status. Cross-sectional study of 582 children aged 6 to 14 years with (n = 304) and without (n = 278) asthma in San Juan, Puerto Rico. Folate deficiency was defined as plasma folate less than or equal to 20 ng/ml. Our outcomes were the number of positive skin tests to allergens (range, 0-15) in all children and (in children with asthma) one or more severe exacerbations in the previous year. Logistic and negative binomial regression models were used for the multivariate analysis. All multivariate models were adjusted for age, sex, household income, residential proximity to a major road, and (for atopy) case/control status; those for severe exacerbations were also adjusted for use of inhaled corticosteroids and vitamin D insufficiency (a plasma 25[OH]D < 30 ng/ml). In a multivariate analysis, folate deficiency was significantly associated with an increased degree of atopy and 2.2 times increased odds of at least one severe asthma exacerbation (95% confidence interval for odds ratio, 1.1-4.6). Compared with children who had normal levels of both folate and vitamin D, those with both folate deficiency and vitamin D insufficiency had nearly eightfold increased odds of one or more severe asthma exacerbation (95% confidence interval for adjusted odds ratio, 2.7-21.6). Folate deficiency is associated with increased degree of atopy and severe asthma exacerbations in school-aged Puerto Ricans. Vitamin D insufficiency may further increase detrimental effects of folate deficiency on severe asthma exacerbations.

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.

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.

Associations between age and patient-reported quality of family planning services were examined among young women in Mexico. A repeated cross-sectional analysis of survey data collected in 2006, 2009, and 2014 was performed. Data from women aged 15-29years who had not undergone sterilization and were currently using a modern contraceptive method were included. The primary outcome was high-quality care, defined as positive responses to all five quality items regarding contraceptive services included in the survey. Multivariable logistic regression and marginal probabilities were used to compare adolescents and women aged 20-29years. The responses of respondents using different contraceptive methods were compared. Data were included from 15 835 individuals. The multivariable analysis demonstrated lower odds of reporting high-quality care among women aged 15-19years (odds ratio 0.73; 95% confidence interval 0.60-0.88) and 20-24years (odds ratio 0.85; 95% confidence interval 0.75-0.96) compared with women aged 25-29years. Adolescents using hormonal and long-acting reversible contraception had significantly lower odds of reporting high-quality care compared with women aged 25-29. Adolescents in Mexico reported a lower quality of family planning services compared with young adult women. Continued research and policies are needed to improve the quality of contraceptive services. Copyright © 2016 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

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.

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.

This retrospective cohort study analyzed the clinical manifestations in patients with preeclampsia and eclampsia, assessed the risk factors compared to the severity of hypertensive disorders on maternal and perinatal morbidity, and mortality between the referral and non-referral patients. 271 pregnant women with preeclampsia and eclampsia were assessed (1993 to 1997). Chi-square analysis was used for the comparison of categorical variables, and the comparison of the two independent variables of proportions in estimation of confidence intervals and calculated odds ratio of the referral and non-referral groups. Multivariate logistic regression was used for adjusting potential confounding risk factors. Of the 271 patients included in this study, 71 (26.2%) patients were referrals from other hospitals. Most of the 62 (87.3%) referral patients were transferred during the period 21 and 37 weeks of gestation. Univariate analysis revealed that referral patients with hypertensive disorder were significantly associated with SBP > or =180, DBP > or =105, severe preclampsia, haemolysis, elevated liver enzymes, low platelets (HELLP), emergency C/S, maternal complications, and low birth weight babies, as well as poor Apgar score. Multivariate logistic regression analyses revealed that the risk factors identified to be significantly associated with increased risk of referral patients included: diastolic blood pressure above 105 mmHg (adjusted odds ratio, 2.09; 95 percent confidence interval, 1.06 to 4.13; P = 0.034), severe preeclampsia (adjusted odds ratio, 3.46; 95 percent confidence interval, 1.76 to 6.81; P < 0.001), eclampsia (adjusted odds ratio, 2.77; 95 percent confidence interval, 0.92 to 8.35; P = 0.071), HELLP syndrome (adjusted odds ratio, 18.81; 95 percent confidence interval, 2.14 to 164.99; P = 0.008). The significant factors associated with the referral patients with hypertensive disorders were severe preeclampsia, HELLP, and eclampsia. Lack of prenatal care was the major avoidable factor found in referral and high risk patients. Time constraints relating to referral patients and the appropriateness of patient-centered care for patient safety and better quality of health care need further investigation on national and multi-center clinical trials.

Background: Pancreatic cancer (PC) is a serious and rapidly progressing malignancy. Identifying risk factors including dietary elements is important to develop preventive strategies. This study focused on possible links between diet and PC. Methods: We conducted a case-control study including all PC patients diagnosed at Minia Cancer Center and controls from general population from June 2014 to December 2015. Dietary data were collected directly through personal interviews. Principal component analysis (PCA) was performed to identify dietary groups. The data were analyzed using crude odds ratios (ORs) and multivariable logistic regression with adjusted ORs and 95% confidence intervals (CIs). Results: A total of 75 cases and 149 controls were included in the study. PCA identified six dietary groups, labeled as cereals and grains, vegetables, proteins, dairy products, fruits, and sugars. Bivariate analysis showed that consumption of vegetables, fruits, sugars, and total energy intake were associated with change in PC risk. In multivariable-adjusted models comparing highest versus lowest levels of intake, we observed significant lower odds of PC in association with vegetable intake (OR 0.24; 95% CI, 0.07-0.85, P=0.012) and a higher likelihood with the total energy intake (OR 9.88; 95% CI, 2.56-38.09, P<0.0001). There was also a suggested link between high fruit consumption and reduced odds of PC. Conclusions: The study supports the association between dietary factors and the odds of PC development in Egypt. It was found that higher energy intake is associated with an increase in likelihood of PC, while increased vegetable consumption is associated with a lower odds ratio.

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.

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.

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).

Objective To conduct a multivariate analysis of a large cohort of oral cavity squamous cell carcinoma (OCSCC) cases for independent predictors of local recurrence (LR) and overall survival (OS), with emphasis on the relationship between (1) prognosis and (2) main specimen permanent margins and intraoperative tumor bed frozen margins. Study Design Retrospective cohort study. Setting Tertiary academic head and neck cancer program. Subjects and Methods This study included 426 patients treated with OCSCC resection between 2005 and 2014 at University of Iowa Hospitals and Clinics. Patients underwent excision of OCSCC with intraoperative tumor bed frozen margin sampling and main specimen permanent margin assessment. Multivariate analysis of the data set to predict LR and OS was performed. Results Independent predictors of LR included nodal involvement, histologic grade, and main specimen permanent margin status. Specifically, the presence of a positive margin (odds ratio, 6.21; 95% CI, 3.3-11.9) or <1-mm/carcinoma in situ margin (odds ratio, 2.41; 95% CI, 1.19-4.87) on the main specimen was an independent predictor of LR, whereas intraoperative tumor bed margins were not predictive of LR on multivariate analysis. Similarly, independent predictors of OS on multivariate analysis included nodal involvement, extracapsular extension, and a positive main specimen margin. Tumor bed margins did not independently predict OS. Conclusion The main specimen margin is a strong independent predictor of LR and OS on multivariate analysis. Intraoperative tumor bed frozen margins do not independently predict prognosis. We conclude that emphasis should be placed on evaluating the main specimen margins when estimating prognosis after OCSCC resection.

Predictors of thirty-day readmission among hospitalized family medicine patients.

Hospital readmissions within 30 days of initial discharge occur frequently. In studies of elderly patients receiving Medicare, readmissions have been associated with poor-quality inpatient care, ineffective hospital-to-home transitions, patient characteristics, disease burden, and socioeconomic status. Among adult family medicine patients spanning a wide age range, we hypothesize that previous hospitalizations, length of stay, number of discharge medications, medical comorbidities, and patient demographics are associated with a greater risk of hospital readmission within 30 days. A retrospective case-control study of 276 family medicine inpatients was conducted to determine the factors associated with 30-day readmission. Bivariate statistics were computed and a multivariate analysis using logistic regression was performed to determine the independent effects of each factor. Patients readmitted within 30 days had more hospitalizations, more emergency department visits, longer hospital stays, more comorbidities, and more discharge medications and were less likely to be married. Multivariate logistic regression found that hospitalization within the previous 12 months (odds ratio, 2.71) and long hospital stays (odds ratio, 2.16) were associated with 30-day readmission; being married (odds ratio, 0.54) had a protective effect. This study demonstrates that factors previously found to be associated with 30-day readmission among elderly patients receiving Medicare also apply to family medicine patients of all ages. It also demonstrates prior hospitalizations, length of stay, and marital status are useful proxies for many more complicated factors, such as disease burden, medical complexity, and social issues, that influence hospital readmission.

To assess the burden of maternal malaria and HIV among pregnant women in Ghana and to determine the risk of anemia among women with dual infection. A cross-sectional study was conducted at 4 hospitals in the Sekondi-Takoradi metropolis, Ghana. The study group comprised 872 consenting pregnant women attending prenatal care clinics. Venous blood samples were screened for malaria, HIV, and hemoglobin level. Multivariate logistic regression analysis was performed to determine the association between malaria, HIV, and risk of anemia. In all, 34.4% of the study cohort had anemia. Multivariate logistic regression analysis indicated that pregnant women with either malaria (odds ratio 1.99; 95% confidence interval, 1.43-2.77; P=<0.001) or HIV (odds ratio 1.78; 95% confidence interval, 1.13-2.80; P=0.014) had an increased risk of anemia. In adjusted models, pregnant women co-infected with both malaria and HIV displayed twice the risk of anemia. The adjusted odds ratio was 2.67 (95% confidence interval, 1.44-4.97; P=0.002). Pregnant women infected with both malaria and HIV are twice as likely to be anemic than women with a single infection or no infection. Measures to control malaria, HIV, and anemia during pregnancy are imperative to improve birth outcomes in this region of Ghana. Copyright © 2012 International Federation of Gynecology and Obstetrics.

Mentorship Programs in Radiation Oncology Residency Training Programs: A Critical Unmet Need

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

Dhami, Gurleen; Gao, Wendy; Gensheimer, Michael F.

Purpose: To conduct a nationwide survey to evaluate the current status of resident mentorship in radiation oncology. Methods and Materials: An anonymous electronic questionnaire was sent to all residents and recent graduates at US Accreditation Council for Graduate Medical Education–accredited radiation oncology residency programs, identified in the member directory of the Association of Residents in Radiation Oncology. Factors predictive of having a mentor and satisfaction with the mentorship experience were identified using univariate and multivariate analyses. Results: The survey response rate was 25%, with 85% of respondents reporting that mentorship plays a critical role in residency training, whereas only 53%more » had a current mentor. Larger programs (≥10 faculty, P=.004; and ≥10 residents, P<.001) were more likely to offer a formal mentorship program, which makes it more likely for residents to have an active mentor (88% vs 44%). Residents in a formal mentoring program reported being more satisfied with the overall mentorship experience (univariate odds ratio 8.77, P<.001; multivariate odds ratio 5, P<.001). On multivariate analysis, women were less likely to be satisfied with the mentorship experience. Conclusions: This is the first survey focusing on the status of residency mentorship in radiation oncology. Our survey highlights the unmet need for mentorship in residency programs.« less

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.

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.

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

Sleep duration has been associated with cardiometabolic risk and mortality. The health-related quality of life represents a patient's comprehensive perception of health and is accepted as a health outcome. We examined the relationship between sleep duration and health-related quality of life in predialysis CKD. In this cross-sectional study, data from 1910 adults with CKD enrolled in the Korean Cohort Study for Outcome in Patients with CKD were analyzed. Health-related quality of life was assessed with the physical component summary and mental component summary of the Short Form-36 Health Survey. Low health-related quality of life was defined as a Short Form-36 Health Survey score >1 SD below the mean. Using a generalized additive model and multivariable logistic regression analysis, the relationship between self-reported sleep duration and health-related quality of life was examined. Seven-hour sleepers showed the highest health-related quality of life. We found an inverted U-shaped relationship between sleep duration and health-related quality of life as analyzed by a generalized additive model. In multivariable logistic analysis, short sleepers (≤5 h/d) had lower health-related quality of life (odds ratio, 3.23; 95% confidence interval, 1.86 to 5.60 for the physical component summary; odds ratio, 2.37; 95% confidence interval, 1.43 to 3.94 for the mental component summary), and long sleepers (≥9 h/d) had lower health-related quality of life (odds ratio, 2.80; 95% confidence interval, 1.55 to 5.03 for the physical component summary; odds ratio, 2.08; 95% confidence interval, 1.20 to 3.60 for the mental component summary) compared with 7-hour sleepers. Sleep duration had a significant U-shaped association with low health-related quality of life. These findings suggest that short or long sleep duration is independently associated with low health-related quality of life in adults with CKD.

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.

Sedentary lifestyle has become prevalent in our community. Recent data showed controversy on the effect of regular exercise on left ventricular compliance and myocardial relaxation. We sought to assess whether physical inactivity is an independent predictor of diastolic dysfunction in or community, after adjustment for several covariates. Consecutive outpatients presenting to the echocardiography laboratory between July 2013 and June 2014 were prospectively enrolled. Clinical variables were collected prospectively at enrollment. Patients were considered physically active if they exercised regularly ≥3× a week, ≥30 minutes each time. The primary endpoint was presence of diastolic dysfunction. The final cohort included 1356 patients (mean age [SD] 52.9 [17.4] years, 51.3% female). Compared with physically active patients, the 1009 (74.4%) physically inactive patients were older, more often female, and had more comorbidities and worse diastolic function (51.3% vs 38.3%; P < 0.001). On univariate analysis, physical inactivity was associated with 70% increased odds of having diastolic dysfunction (odds ratio: 1.70, 95% confidence interval: 1.32-2.18, P < 0.001). There was significant interaction between physical activity and left ventricular mass index (LVMI; P = 0.026). On multivariate analysis, patients who were physically inactive and had LVMI ≥ median had significantly higher odds of having diastolic dysfunction (odds ratio: 2.82, 95% confidence interval: 1.58-5.05, P < 0.001). In a large, prospectively enrolled cohort from a single tertiary center in the Middle East, physically inactive patients with increased LVMI had 2- to 3-fold increased odds of having diastolic dysfunction after multivariate adjustment. © 2016 Wiley Periodicals, Inc.

Purpose Tobacco use using a waterpipe is an emerging trend among college students. Although cigarette smoking is low among college athletes, waterpipe tobacco smoking may appeal to this population. The purpose of this study was to compare cigarette and waterpipe tobacco smoking in terms of their associations with organized sport participation. Methods In the spring of 2008, we conducted an online survey of 8,745 college students at eight institutions as part of the revised National College Health Assessment. We used multivariable regression models to assess the associations between tobacco use (cigarette and waterpipe) and organized sports participation. Results Participants reported participation in varsity (5.2%), club (11.9%), and intramural (24.9%) athletics. Varsity athletes and individuals who were not varsity athletes had similar rates of waterpipe tobacco smoking (27.6% vs. 29.5%, p = .41). However, other types of athletes were more likely than their counterparts to have smoked waterpipe tobacco (35.1% vs. 28.7%, p < .001 for club sports and 34.8% vs. 27.7%, p < .001 for intramural sports). In fully-adjusted multivariable models, sports participants of any type had lower odds of having smoked cigarettes, whereas participants who played intramural sports (odds ratio = 1.15, 95% confidence interval = 1.03, 1.29) or club sports (odds ratio = 1.15, 95% confidence interval = 1.001, 1.33) had significantly higher odds of having smoked waterpipe tobacco. Conclusions College athletes are susceptible to waterpipe tobacco use. In fact, compared with their nonathletic counterparts, club sports participants and intramural sports participants generally had higher odds of waterpipe tobacco smoking. Allure for waterpipe tobacco smoking may exist even for individuals who are traditionally considered at low risk for tobacco use. PMID:20123257

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.

Background: Little is known about folate and atopy or severe asthma exacerbations. We examined whether folate deficiency is associated with number of positive skin tests to allergens or severe asthma exacerbations in a high-risk population and further assessed whether such association is explained or modified by vitamin D status. Methods: Cross-sectional study of 582 children aged 6 to 14 years with (n = 304) and without (n = 278) asthma in San Juan, Puerto Rico. Folate deficiency was defined as plasma folate less than or equal to 20 ng/ml. Our outcomes were the number of positive skin tests to allergens (range, 0–15) in all children and (in children with asthma) one or more severe exacerbations in the previous year. Logistic and negative binomial regression models were used for the multivariate analysis. All multivariate models were adjusted for age, sex, household income, residential proximity to a major road, and (for atopy) case/control status; those for severe exacerbations were also adjusted for use of inhaled corticosteroids and vitamin D insufficiency (a plasma 25[OH]D < 30 ng/ml). Measurements and Main Results: In a multivariate analysis, folate deficiency was significantly associated with an increased degree of atopy and 2.2 times increased odds of at least one severe asthma exacerbation (95% confidence interval for odds ratio, 1.1–4.6). Compared with children who had normal levels of both folate and vitamin D, those with both folate deficiency and vitamin D insufficiency had nearly eightfold increased odds of one or more severe asthma exacerbation (95% confidence interval for adjusted odds ratio, 2.7–21.6). Conclusions: Folate deficiency is associated with increased degree of atopy and severe asthma exacerbations in school-aged Puerto Ricans. Vitamin D insufficiency may further increase detrimental effects of folate deficiency on severe asthma exacerbations. PMID:26561879

Effect of aspirin in pregnant women is dependent on increase in bleeding time.

Randomized trials with low-dose aspirin to prevent preeclampsia and intrauterine growth restriction have yielded conflicting results. In particular, 3 recent large trials were not conclusive. Study designs, however, varied greatly regarding selection of patients, dose of aspirin, and timing of treatment, all of which can be determinants of the results. Retrospectively analyzing the conditions associated with failure or success of aspirin may therefore help to draw up new hypotheses and prepare for more specific randomized trials. We studied a historical cohort of 187 pregnant women who were considered at high risk for preeclampsia, intrauterine growth restriction, or both and were therefore treated with low-dose aspirin between 1989 and 1994. Various epidemiologic, clinical, and laboratory data were extracted from the files. Univariate and multivariate analyses were performed to search for independent parameters associated with the outcome of pregnancy. Age, parity, weight, height, and race had no influence on the outcome. The success rate was higher when treatment was given because of previous poor pregnancy outcomes than when it was given for other indications, and the patients with successful therapy had started aspirin earlier than had those with therapy failure (17.7 vs 20.0 weeks' gestation, P =.04). After multivariate analysis an increase in Ivy bleeding time after 10 days of treatment by >2 minutes was an independent predictor of a better outcome (odds ratio 0.22, 95% confidence interval 0.09-0.51). Borderline statistical significance was observed for aspirin initiation before 17 weeks' gestation (odds ratio 0.44, 95% confidence interval 0.18-1. 08). Abnormal uterine artery Doppler velocimetric scan at 20-24 weeks' gestation (odds ratio 3.31, 95% confidence interval 1.41-7.7), abnormal umbilical artery Doppler velocimetric scan after 26 weeks' gestation (odds ratio 37.6, 95% confidence interval 3.96-357), and use of antihypertensive therapy (odds ratio 6.06, 95% confidence interval 2.45-15) were independent predictors of poor outcome. Efficacy of aspirin seems optimal when bleeding time increases >/=2 minutes with treatment, indicating a more powerful antiplatelet effect. This suggests that the dose of aspirin should be adjusted according to a biologic marker of the antiplatelet effect. A prospective trial is warranted to test this hypothesis.

This study explored the prevalence, disparity, and cohort trends in suicidality among bisexual teens vs. heterosexual and gay/lesbian peers in 9 population-based high school surveys in Canada and the U.S. Multivariate logistic regressions were used to calculate age-adjusted odds ratios separately by gender; 95% confidence intervals tested cohort trends where surveys were repeated over multiple years. Results showed remarkable consistency: bisexual youth reported higher odds of recent suicidal ideation and attempts vs. heterosexual peers, with increasing odds in most surveys over the past decade. Results compared to gay and lesbian peers were mixed, with varying gender differences in prevalence and disparity trends in the different regions. PMID:19835039

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.

The role of hepatitis virus infection in glucose homeostasis is uncertain. We examined the associations between hepatitis B virus (HBV) or hepatitis C virus (HCV) infection and the development of diabetes in a cohort (N = 439,708) of asymptomatic participants in health screening examinations. In cross-sectional analyses, the multivariable-adjusted odds ratio for prevalent diabetes comparing hepatitis B surface antigen (HBsAg) (+) to HBsAg (-) participants was 1.17 (95% CI 1.06-1.31; P = 0.003). The corresponding odds ratio comparing hepatitis C antibodies (HCV Ab) (+) to HCV Ab (-) participants was 1.43 (95% CI 1.01-2.02, P = 0.043). In prospective analyses, the multivariable-adjusted hazard ratio for incident diabetes comparing HBsAg (+) to HbsAg (-) participants was 1.23 (95% CI 1.08-1.41; P = 0.007). The number of incident cases of diabetes among HCV Ab (+) participants (10 cases) was too small to reliably estimate the prospective association between HCV infection and diabetes. In this large population at low risk of diabetes, HBV and HCV infections were associated with diabetes prevalence and HBV infection with the risk of incident diabetes. Our studies add evidence suggesting that diabetes is an additional metabolic complication of HBV and HCV infection.

The neutrophil-to-lymphocyte ratio (NLR) has been used as a surrogate marker of systemic inflammation. We sought to investigate the association between NLR and wound healing in diabetic wounds. The outcomes of 120 diabetic foot ulcers in 101 patients referred from August 2011 to December 2014 were examined retrospectively. Demographic, patient-specific, and wound-specific variables as well as NLR at baseline visit were assessed. Outcomes were classified as ulcer healing, minor amputation, major amputation, and chronic ulcer. The subjects' mean age was 59.4 ± 13.0 years, and 67 (66%) were male. Final outcome was complete healing in 24 ulcers (20%), minor amputation in 58 (48%) and major amputation in 16 (13%), and 22 chronic ulcers (18%) at the last follow-up (median follow-up time, 6.8 months). In multivariate analysis, higher NLR (odds ratio, 13.61; P = .01) was associated with higher odds of nonhealing. NLR can predict odds of complete healing in diabetic foot ulcers independent of wound infection and other factors. Copyright © 2016 Society for Vascular Surgery. All rights reserved.

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.

The authors’ objective was to discern whether lifestyle or health-related factors were confounders, effect modifiers, or irrelevant with regard to understanding observational associations of serum 25-hydroxyvitamin D (25(OH)D) with colorectal and breast cancer. The authors conducted nested case-control studies of colorectal cancer (310 cases, 310 controls) and breast cancer (1,080 cases, 1,080 controls) in the Women’s Health Initiative Calcium and Vitamin D Clinical Trial (1994–2005). Case-control matching factors included age, latitude, race/ethnicity, and blood collection date. Serum 25(OH)D was assayed in baseline fasting blood. Conditional logistic regression was used to estimate odds ratios for each cancer by serum 25(OH)D concentration, comparing the relative effects of successively adding body mass index, physical activity, and other health and lifestyle characteristics particular to each cancer. In models with matching factors only, low (vs. high) serum 25(OH)D was associated with a colorectal cancer odds ratio of 2.72 (95% confidence interval (CI): 1.55, 4.77) and a breast cancer odds ratio of 1.33 (95% CI: 1.02, 1.72). In multivariate-adjusted models for colorectal cancer, the association strengthened (OR = 4.45, 95% CI: 1.96, 10.10). However, in multivariate-adjusted breast cancer models, associations were no longer significant (OR = 1.06, 95% CI: 0.78, 1.43). Adjusting for health and lifestyle characteristics has differential effects depending on the cancer site; when modeling such relations, investigators should take these factors into account.

The relative virulence (defined as odds ratio) associated with different O and K antigens, adhesins and hemolysin production of Escherichia coli strains was assessed by separate and multivariate logistic regression analyses comparing 383 strains isolated from urine of adults with a urinary tract infection with 287 fecal strains from healthy adults; special interest was paid to evaluating the role of type 1C fimbriation. Type 1C fimbriae, found on 14% of UTI and 7% of fecal strains, were associated with O groups O2, O6, O18, and O75, with capsular type K5, with mannose-resistant (both P and non-P) adhesins, and with hemolysin production. In separate analyses, O8 (odds ratio 5.9) and O75 (9.2), capsular types other than K1 (1.9-2.1), P (2.9) and non-P mannose-resistant (17.4) adhesins, and hemolysin production (3.1) were each associated with high relative virulence compared to O1, Rough, and K1 phenotypes or lack of mannose-resistant adhesins or hemolysin. All these virulence effects were independent of type 1C fimbriation. In multivariate analysis, joint variation between factors decreased the apparent virulence-promoting effect of type 1C fimbriae, O6 antigen and hemolysin but increased that of other adhesins. Especially high relative virulence (odds ratio 404.2) was associated with the combination of O75:K5:non-P mannose-resistant adhesin identified on seven UTI but no fecal strains.

Anaemia in children living in sub-Saharan Africa is common, but its causes are diverse. In 545 children below 5 years of age from rural southern Rwanda, we assessed the role of iron deficiency (ID) and of the TMPRSS6 736(V) (rs855791) allele, known to reduce iron status and haemoglobin (Hb) levels, in anaemia and Hb concentrations. Anaemia (Hb <11 g/dl) was present in 34.4% of the children and ID (ferritin <12 ng/ml) in 17.6%. The TMPRSS6 736(V) allele was uncommon (allele frequency, 0.096) and not associated with ID. In multivariate analysis, ID was positively associated with anaemia (adjusted odds ratio, 1.67) to an extent comparable with α(+) -thalassaemia, breastfeeding, inflammation and low household income, but the odds were substantially higher in Plasmodium falciparum infection (adjusted odds ratio, 10.3). These findings were verified in a multivariate analysis of Hb concentrations. The TMPRSS6 736(V) allele only tended to be associated with low Hb levels. TMPRSS6 736(V) is comparatively rare among Rwandan children and may only slightly contribute to low Hb concentrations. Preventable causes of anaemia, notably ID and P. falciparum infection, largely outweigh its impact and need to be addressed to improve the haematological status of children in the study area. © 2013 John Wiley & Sons Ltd.

Food insecurity may be a barrier to achieving optimal HIV treatment-related outcomes among illicit drug users. This study therefore, aimed to assess the impact of severe food insecurity, or hunger, on plasma HIV RNA suppression among illicit drug users receiving antiretroviral therapy (ART). A cross-sectional Multivariate logistic regression model was used to assess the potential relationship between hunger and plasma HIV RNA suppression. A sample of n = 406 adults was derived from a community-recruited open prospective cohort of HIV-positive illicit drug users, in Vancouver, British Columbia (BC), Canada. A total of 235 (63.7%) reported "being hungry and unable to afford enough food," and 241 (59.4%) had plasma HIV RNA < 50 copies/ml. In unadjusted analyses, self-reported hunger was associated with lower odds of plasma HIV RNA suppression (Odds Ratio = 0.59, 95% confidence interval [CI]: 0.39-0.90, p = 0.015). In multivariate analyses, this association was no longer significant after controlling for socio-demographic, behavioral, and clinical characteristics, including 95% adherence (Adjusted Odds Ratio [AOR] = 0.65, 95% CI: 0.37-1.10, p = 0.105). Multivariate models stratified by 95% adherence found that the direction and magnitude of this association was not significantly altered by the adherence level. Hunger was common among illicit drug users in this setting. Although, there was an association between hunger and lower likelihood of plasma HIV RNA suppression, this did not persist in adjusted analyses. Further research is warranted to understand the social-structural, policy, and physical factors shaping the HIV outcomes of illicit drug users.

Background Obesity increases risk of premature disease, and may be associated with unfavorable lifestyle changes that add to risk. This study analyzed the association of midlife BMI change with current lifestyle patterns among multiethnic men. Methods Men aged 40-60 years (n=9864) retrospectively reported body weight between ages 20-40 years and current dietary, TV, physical activity and sleep practices in the Adventist Health Study II, a study of church-goers in the US and Canada. In multivariate logistic regression analysis, odds ratios for BMI gain were calculated for each lifestyle practice controlling for sociodemographic and other lifestyle factors and current BMI. Results Men with median or higher BMI gain (2.79 kg/m2) between ages 20-40 years were more likely to consume a non-vegetarian diet, and engage in excessive TV watching and little physical activity and had a shorter sleep duration compared to men with BMI gain below the median (all p<0.001). In multivariate logistic analysis current BMI was significantly associated with all lifestyle factors in multivariate analyses (all p≤0.005). BMI gain was associated with lower odds of vegetarian diet (odds ratio [OR] 0.939; 95% confidence interval [CI] 0.921-0.957) and of physical activity ≥150 minutes/week (OR 0.979, 95% CI 0.960-0.999). Conclusions These findings imply that diet and less physical activity are associated with both gained and attained BMI, while inactivity (TV watching) and short sleep duration correlated only with attained BMI. Unhealthy lifestyle may add risk to that associated with BMI. Longitudinal and intervention studies are needed to infer causal relationships. PMID:25434910

To use ecological momentary assessment techniques to measure the association of major depressive disorder (MDD) with media use. Data were collected using an ecological momentary assessment protocol with cellular telephone-based brief interviews. Participants received as many as 60 telephone calls from a trained staff member during 5 extended weekends in an 8-week period. One hundred six adolescent participants who were part of a larger neurobehavioral study of depression in Pittsburgh from January 1, 2003, through December 31, 2008. At each call, participants were asked whether they were using the following 5 types of media: television or movies, music, video games, Internet, and print media, such as magazines, newspapers, and books. We developed multivariable models to determine the independent association of each type of media use with MDD, controlling for sociodemographic variables. Of the 106 participants, 46 were diagnosed as having MDD. In multivariable models controlling for age, sex, and race, each increasing quartile of audio use was associated with an 80% increase in the odds of having MDD (odds ratio, 1.8; 95% confidence interval, 1.1-2.8; P = .01 for trend). Conversely, each increasing quartile of print media use was associated with a 50% decrease in the odds of having MDD (odds ratio, 0.5; 95% confidence interval, 0.3-0.9; P = .009 for trend). Major depressive disorder is positively associated with popular music exposure and negatively associated with reading print media such as books. Further research elucidating the directionality and strength of these relationships may help advance understanding of the relationships between media use and MDD.

Purpose Little is known about the risk factors for nonmedical use (NMU) of prescription stimulants among adolescent girls. We aimed to measure the association of nonmedical prescription stimulant use with empirically linked risk factors, including weight control behavior (WCB), gambling, and depressed mood, in pre-teen and teenaged girls. Methods We assessed the relationship between age and race, gambling, WCB, depressive mood, and nonmedical prescription stimulant use using multivariable logistic regression. The study sample included 5,585 females, aged 10–18 years, recruited via an entertainment venue intercept method in 10 U.S. metropolitan areas as part of the National Monitoring of Adolescent Prescription Stimulants Study (2008–2011). Results NMU of prescription stimulants was reported by 6.6% (n = 370) of the sample. In multivariable logistic regression, 1-year increase in age was associated with a 21% (95% confidence interval [CI]: .15, .28) increase in risk for NMU. Whites and other race/ethnicity girls had 2.67 (CI: 1.85, 3.87) and 1.71 (1.11, 2.65) times higher odds for NMU, compared to African-Americans. Depressive mood (adjusted odds ratio: 2.69, CI: 2.04, 5.57) and gambling (adjusted odds ratio: 1.90, 1.23, 2.92) were associated with increased odds for NMU. A dose-response was identified between WCB and NMU, where girls with unhealthy and extreme WCB were over five times more likely to endorse NMU. Conclusions We contribute to the literature linking WCB, depression, gambling, and the NMU of prescription stimulants in any population and uniquely do so among girls. PMID:27998704

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.

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 determine the prevalence of exclusive breast feeding in working women and to identify the factors effecting exclusive breast feeding in working women. This cross-sectional survey was conducted in Faisalabad city within a period of six months from June 2016 to December 2016. Working women of age 18 to 45 years, working as doctors, teachers, nurses and bankers in public (government) setup were included. The data was collected using interview method by pre-structured questionnaire. Multi-variable logistic regression model was developed considering EBF practice as dependent and the significant independent variables. Results were reported as Crude Odds Ratio (COR) or Adjusted Odds Ratio (AOR) with 95% Confidence Intervals (CIs). Prevalence of exclusive breast feeding (EBF) was 166 (41.5%). EFB practice was significantly less in doctors and bankers as compared to nurses and teachers (p-value <0.001). Women working as nurses and teachers, having one or two children and short working hours had higher prevalence of exclusive breast feeding. Women having prior knowledge about EBF, training of EBF and women who had previously heard about EBF had five time higher rate of breast feeding. Women having knowledge of colostrum had three times higher EBF practice [odds ratio: 3.02 (1.86-4.91)]. Women having knowledge about hazards of bottle feeding had 12.7 times higher prevalence of EBF [odds ratio: 12.72 (5.70-28.38)]. Those who knew about expression of breast milk had three times higher prevalence of EBF [odds ratio: 3.0 (1.98-4.55)]. Mothers working in organizations that support EBF had 4.1 times higher prevalence of EBF [odds ratio: 4.1 (2.67-6.21)]. And proper training of mothers about correct expression technique of breast milk had 12 time [odds ratio: 12.06 (4.97-29.23)] higher prevalence of EBF. Long working hours, banking profession, family income and lack of proper knowledge about exclusive breast feeding are responsible for non-EBF practice in working women. Proper Knowledge and awareness about exclusive breastfeeding and provision of facilities for exclusive breastfeeding (EBF) by the organizations can play a significant role in promoting it.

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.

Retrospective cohort, women, singleton pregnancies (UK 2011-2015). Unadjusted and multivariable logistic regression. small for gestational age (SGA), pre-eclampsia (PE), preterm birth (PTB), miscarriage, stillbirth, perinatal mortality and neonatal death (NND). A total of 12 592 pregnancies: 852 (6.8%) PTB, 352 (2.8%) PE, 1824 (14.5%) SGA, 73 (0.6%) miscarriages, 37(0.3%) stillbirths, 73 perinatal deaths (0.6%) and 38 (0.30%) NND. Multivariable analysis: lower odds of SGA [adjusted odds ratio (aOR) 0.88 (95% CI 0.85,0.91)], PTB [0.92 (95%CI 0.88,0.97)], PE [0.91 (95% CI 0.85,0.97)] and stillbirth [0.71 (95% CI 0.52,0.98)] as PAPP-A increases. Lower odds of SGA [aOR 0.79 (95% CI 0.70,0.89)] but higher odds of miscarriage [aOR 1.75 95% CI (1.12,2.72)] as NT increases, and lower odds of stillbirth as CRL increases [aOR 0.94 95% CI (0.89,0.99)]. Multivariable analysis of three factors together demonstrated strong associations: a) PAPP-A, NT, CRL and SGA, b) PAPP-A and PTB, c) PAPP-A, CRL and PE, d) NT and miscarriage. Pregnancy-associated plasma protein-A, NT and CRL are independent prognostic factors for adverse pregnancy outcomes, particularly PAPP-A and SGA with lower PAPP-A associated with increased risk. © 2017 John Wiley & Sons, Ltd. © 2017 John Wiley & Sons, Ltd.

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.

Background This study explored the relationship between the knowledge of community health workers (CHWs)—anganwadi workers (AWWs) and auxiliary nurse midwives (ANMs)—and their antenatal home visit coverage and effectiveness of the visits, in terms of essential newborn health care practices at the household level in rural India. Methods We used data from 302 AWWs and 86 ANMs and data from recently delivered women (RDW) (n = 13 023) who were residents of the CHW catchment areas and gave birth to a singleton live baby during 2004–05. Using principal component analysis, knowledge scores for preventive care and danger signs were computed separately for AWWs and ANMs and merged with RDW data. A multivariate logistic regression model was used to estimate the adjusted effect of knowledge level. A generalized estimating equation (GEE) was used to account for clustering. Results Coverage of antenatal home visits and newborn care practices were positively correlated with the knowledge level of AWWs and ANMs. Initiation of breastfeeding in the first hour of life (odds ratio 1.97; 95% confidence interval (CI): 1.55–2.49 for AWW, and odds ratio 1.62; 95% CI: 1.25–2.09 for ANM), clean cord care (odds ratio 2.03; 95% CI: 1.64–2.52 for AWW, and odds ratio 1.43; 95% CI: 1.17–1.75 for ANM) and thermal care (odds ratio 2.16; 95% CI: 1.64–2.85 for AWW and odds ratio 1.88; 95% CI: 1.43–2.48 for ANM) were significantly higher among women visited by AWWs or ANMs who had better knowledge compared with those with poor knowledge. Conclusion CHWs’ knowledge is one of the crucial aspects of health systems to improve the coverage of community-based newborn health care programmes as well as adherence to essential newborn care practices at the household level.

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.

In adults, early traumatic coagulopathy and shock are both common and independently associated with mortality. There are little data regarding both the incidence and association of early coagulopathy and shock on outcomes in pediatric patients with traumatic injuries. Our objective was to determine whether coagulopathy and shock on admission are independently associated with mortality in children with traumatic injuries. A retrospective review of the Joint Theater Trauma Registry from U.S. combat support hospitals in Iraq and Afghanistan from 2002 to 2009 was performed. Coagulopathy was defined as an international normalized ratio of ≥1.5 and shock as a base deficit of ≥6. Laboratory values were measured on admission. Primary outcome was inhospital mortality. Univariate analyses were performed on all admission variables followed by reverse stepwise multivariate logistic regression to determine independent associations. Combat support hospitals in Iraq and Afghanistan. Patients <18 yrs of age with Injury Severity Score, international normalized ratio, base deficit, and inhospital mortality were included. Of 1998 in the cohort, 744 (37%) had a complete set of data for analysis. None. The incidence of early coagulopathy and shock were 27% and 38.3% and associated with mortality of 22% and 16.8%, respectively. After multivariate logistic regression, early coagulopathy had an odds ratio of 2.2 (95% confidence interval 1.1-4.5) and early shock had an odds ratio of 3.0 (95% confidence interval 1.2-7.5) for mortality. Patients with coagulopathy and shock had an odds ratio of 3.8 (95% confidence interval 2.0-7.4) for mortality. In children with traumatic injuries treated at combat support hospitals, coagulopathy and shock on admission are common and independently associated with a high incidence of inhospital mortality. Future studies are needed to determine whether more rapid and accurate methods of measuring coagulopathy and shock as well as if early goal-directed treatment of these states can improve outcomes in children.

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. Certain large breeds were highly predisposed. © 2017 British Small Animal Veterinary Association.

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.

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.

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

The objective of this study was to examine the relationship between chronic osteomyelitis and acute pancreatitis in Taiwan. This was a population-based case-control study utilizing the database of the Taiwan National Health Insurance Program. We identified 7678 cases aged 20-84 with newly diagnosed acute pancreatitis during the period of 1998 to 2011. From the same database, 30,712 subjects without diagnosis of acute pancreatitis were selected as controls. The cases and controls were matched with sex, age and index year of diagnosing acute pancreatitis. The odds ratio with 95% confidence interval of acute pancreatitis associated with chronic osteomyelitis was examined by the multivariable unconditional logistic regression analysis. After adjustment for multiple confounders, the multivariable analysis showed that the adjusted odds ratio of acute pancreatitis was 1.93 for subjects with chronic osteomyelitis (95% confidence interval 1.01, 3.69), when compared with subjects without chronic osteomyelitis. Chronic osteomyelitis correlates with increased risk of acute pancreatitis. Patients with chronic osteomyelitis should be carefully monitored about the risk of acute pancreatitis.

Aboriginal leadership and families are deeply concerned about the rate of suicide attempt among their young people. The objectives of this study were to (a) describe the prevalence of suicide attempt and (b) to describe correlates of vulnerability to suicide attempts within a cohort of young Aboriginal people who use drugs in 2 Canadian cities. We aimed to situate the findings within the context of historical and lifetime trauma. Study design. The Cedar Project is a prospective cohort study involving 605 young Aboriginal people aged 14-30 who use drugs in Vancouver and Prince George, British Columbia, Canada. Multivariable logistic regression modelling identified independent predictors of suicide attempts. Estimates of adjusted odds ratios and 95% confidence intervals were calculated. In multivariable analysis, residing in Prince George (Adjusted Odds Ratio [AOR]: 1.80, 95% CI: 1.23, 2.64), ever having been sexually abused (AOR: 2.07, 95% CI: 1.39, 3.08), and ever having overdosed (AOR: 2.29, 95% CI: 1.53, 3.42) independently predicted lifetime attempted suicide. Suicide prevention and intervention programs must address historical and lifetime trauma among Aboriginal young people who struggle with substance dependence.

The East Harlem (EH), Central Harlem (CH), and Upper East Side (UES) neighborhoods of New York City are geographically contiguous to tertiary medical care, but are characterized by cancer mortality rate disparities. This ecological study aims to disentangle the effects of race and neighborhood on cancer deaths. Mortality-to-incidence ratios were determined using neighborhood-specific data from the New York State Cancer Registry and Vital Records Office (2007-2011). Ecological data on modifiable cancer risk factors from the New York City Community Health Survey (2002-2006) were stratified by sex, age group, race/ethnicity, and neighborhood and modeled against stratified mortality rates to disentangle race/ethnicity and neighborhood using logistic regression. Significant gaps in mortality rates were observed between the UES and both CH and EH across all cancers, favoring UES. Mortality-to-incidence ratios of both CH and EH were similarly elevated in the range of 0.41-0.44 compared with UES (0.26-0.30). After covariate and multivariable adjustment, black race (odds ratio=1.68; 95% confidence interval: 1.46-1.93) and EH residence (odds ratio=1.20; 95% confidence interval: 1.07-1.35) remained significant risk factors in all cancers' combined mortality. Mortality disparities remain among EH, CH, and UES neighborhoods. Both neighborhood and race are significantly associated with cancer mortality, independent of each other. Multivariable adjusted models that include Community Health Survey risk factors show that this mortality gap may be avoidable through community-based public health interventions.

The aim of this study is to determine odds of aggression and associated factors in patients with schizophrenia-spectrum disorders (SSD) and affective disorders who were evaluated in an emergency department setting. A retrospective study was conducted using de-identified data from electronic medical records from 3.322 patients who were evaluated at emergency psychiatric settings. Data extracted included demographic information, variables related to aggression towards people or property in the past 6months, and other factors that could potentially impact the risk of aggression, such as comorbid diagnoses, physical abuse and sexual abuse. Bivariate analyses and multivariate regression analyses were conducted to determine the variables significantly associated with aggression. An initial multivariate regression analysis showed that SSD had 3.1 times the odds of aggression, while bipolar disorder had 2.2 times the odds of aggression compared to unipolar depression. A second regression analysis including bipolar subtypes showed, using unipolar depression as the reference group, that bipolar disorder with a recent mixed episode had an odds ratio (OR) of 4.3, schizophrenia had an OR of 2.6 and bipolar disorder with a recent manic episode had an OR of 2.2. Generalized anxiety disorder was associated with lower odds in both regression analyses. As a whole, the SSD group had higher odds of aggression than the bipolar disorder group. However, after subdividing the groups, schizophrenia had higher odds of aggression than bipolar disorder with a recent manic episode and lower odds of aggression than bipolar disorder with a recent mixed episode.

Neuroform and Enterprise are widely used self-expanding stents designed to treat wide-necked intracranial aneurysms. To assess the incidence, clinical significance, predictors, and outcomes of in-stent stenosis (ISS). Angiographic studies and hospital records were retrospectively reviewed for 435 patients treated between 2005 and 2011 in our institution. A multivariable regression analysis was conducted to determine the predictors of ISS. The Neuroform stent was used in 264 patients (60.7%) and the Enterprise in 171 patients (39.3%). A total of 11 patients (2.5%) demonstrated some degree of ISS during the follow-up period at a mean time point of 4.2 months (range, 2-12 months). The stenosis was mild (< 50%) in 8 patients (1.8%), moderate (50-75%) in 2 patients (0.5%), and severe (> 75%) in 1 patient (0.2%). No patients were symptomatic or required further intervention. There was complete ISS resolution in 2 patients, partial resolution in 2 patients, and no change in 5 patients on follow-up angiography. Patients developing ISS were significantly younger than those without ISS (40.3 vs. 54.9 years; P < .001). ISS rates were 2.7% with the Neuroform and 2.3% with the Enterprise stent (P = .6). In multivariable analysis, younger patient age (odds ratio = 0.92; P = .008), carotid ophthalmic aneurysm location (odds ratio = 7.7; P =0.01), and carotid terminus aneurysm location (odds ratio = 8.1; P = .009) were strong independent predictors of ISS. The type of stent was not a predictive factor. Neuroform and Enterprise ISS is an uncommon, often transient, and clinically benign complication. Younger patients and those harboring anterior circulation aneurysms located at ophthalmic and carotid terminus locations are more likely to develop ISS.

Background Early life risk factors for breast cancer have been investigated in relation to hormonal, nutritional, infectious, and/or genetic hypotheses. Recently, studies of potential health effects associated with exposure to environmental contaminants in breastmilk have been considered. Methods We analyzed data from a population-based case-control study of female Wisconsin residents. Cases (N=2,016) had an incident diagnosis of invasive breast cancer in 2002−2006 reported to the statewide tumor registry. Controls (N=1,960) of similar ages were randomly selected from driver's license lists. Risk factor information was collected during structured telephone interviews. Odds ratios (ORs) and 95% confidence intervals (CI) were estimated from multivariable logistic regression. Results In multivariable models, maternal age and birth order were not associated with breast cancer risk in the full study population. The odds ratio for breast cancer risk associated with having been breastfed in infancy was 0.83 (95% CI 0.72−0.96). In analyses restricted to breastfed women, maternal age associations with breast cancer were null (p-value=0.2). Increasing maternal age was negatively associated with breast cancer risk among women who were not breastfed; the odds ratio for breast cancer associated with each 5-year increase in maternal age was 0.90 (95% CI 0.82−1.00). Higher birth order was inversely associated with breast cancer risk among breastfed women (OR=0.58; 95% CI 0.39−0.86 for women with ≥3 older siblings compared to first-born women) but not among non-breastfed women (OR=1.13; 95% CI 0.81−1.57). Conclusion These findings suggest that early life risk factor associations for breast cancer may differ according to breastfeeding status in infancy. PMID:18379425

The treatment failure and reinfection rates among syphilis patients are high, and relevant studies in China are limited. The aim of this study was to detect the rates of treatment failure and reinfection after syphilis treatment and to explore the potential associated factors. We conducted a longitudinal cohort study in a sexually transmitted disease clinic, the Department of Dermatology and Venereology in Nanshan Center for Chronic Disease Control. Serological testing was performed at baseline and throughout the 2-year follow-up for syphilis patients. To identify potential predictors of treatment outcomes, multivariate logistics analyses were utilized to compare the demographic and clinical characteristics of patients with serological failure/reinfection to those with serological cure/serofast. From June 2011 to June 2016, a total of 1133 patients were screened for syphilis. Among the 770 patients who completed the 2-year follow-up, 510 first-diagnosed patients were included in the final analysis. Multivariate logistics analysis revealed the stage of syphilis (secondary syphilis VS. primary syphilis: adjusted odds ratio, 3.50; 95% confidence interval, 1.11-15.47; p = 0.04), HIV status (positive VS. negative: adjusted odds ratio, 3.06; 95% confidence interval, 1.15-8.04; p = 0.02) and frequency of condom use (always use VS. never use: adjusted odds ratio, 0.28; 95% confidence interval 0.08-0.75; p = 0.02) were significantly associated with the serological outcome. The clinical implications of our findings suggest that it is very important to perform regular clinical and serologic evaluations after treatment. Health counseling and safety education on sex activity should be intensified among HIV-infected patients and secondary syphilis patients after treatment.

Intrapartum maternal fever is associated with several adverse neonatal outcomes. Intrapartum fever can be infectious or inflammatory in etiology. Increases in interleukin 6 and other inflammatory markers are associated with maternal fever. Magnesium has been shown to attenuate interleukin 6-mediated fever in animal models. We hypothesized that parturients exposed to intrapartum magnesium would have a lower incidence of fever than nonexposed parturients. In this study, electronic medical record data from all deliveries at Northwestern Memorial Hospital (Chicago, Illinois) between 2007 and 2014 were evaluated. The primary outcome was intrapartum fever (temperature at or higher than 38.0°C). Factors associated with the development of maternal fever were evaluated using a multivariable logistic regression model. Propensity score matching was used to reduce potential bias from nonrandom selection of magnesium administration. Of the 58,541 women who met inclusion criteria, 5,924 (10.1%) developed intrapartum fever. Febrile parturients were more likely to be nulliparous, have used neuraxial analgesia, and have been delivered via cesarean section. The incidence of fever was lower in women exposed to magnesium (6.0%) than those who were not (10.2%). In multivariable logistic regression, women exposed to magnesium were less likely to develop a fever (adjusted odds ratio = 0.42 [95% CI, 0.31 to 0.58]). After propensity matching (N = 959 per group), the odds ratio of developing fever was lower in women who received magnesium therapy (odds ratio = 0.68 [95% CI, 0.48 to 0.98]). Magnesium may play a protective role against the development of intrapartum fever. Future work should further explore the association between magnesium dosing and the incidence of maternal fever.

The correlation between simvastatin use and acute pancreatitis is explored. A case-control study was conducted to analyze claim data from the Taiwan National Health Insurance Program. The case group comprising a total of 3882 subjects aged 20 to 84 years with their first acute pancreatitis episode occurring between 1998 and 2011 formed the case group, against 3790 randomly selected controls matched for sex, age, comorbidities, and index year of acute pancreatitis diagnosis. Recent use of simvastatin was defined as subjects whose last remaining simvastatin tablet was noted ≤7 days before the date of acute pancreatitis diagnosis. Remote use of simvastatin was defined as subjects whose last remaining 1 tablet for simvastatin was noted >7 days before the date of acute pancreatitis diagnosis. Never use of simvastatin was defined as subjects who had never been prescribed simvastatin. A multivariable unconditional logistic regression model was used to estimate the odds ratio and 95%CI to explore the correlation between simvastatin use and acute pancreatitis. After adjustment for confounders, multivariable logistic regression analysis revealed that the adjusted odds ratio of acute pancreatitis was 1.3 for subjects with recent use of simvastatin (95%CI 1.02, 1.73), when compared with those with never use of simvastatin. The crude odds ratio decreased to 1.1 for those with remote use of simvastatin (95%CI 0.93, 1.34) but without statistical significance. Recent use of simvastatin is associated with acute pancreatitis. Clinicians should consider the possibility of simvastatin-associated acute pancreatitis for patients presenting for acute pancreatitis without known cause. © 2017, The American College of Clinical Pharmacology.

Malnutrition is an established risk factor for postoperative complications. The purpose of this investigation was to determine the overall prevalence of malnutrition in total shoulder arthroplasty (TSA) patients, the differences in prevalence across obesity subgroups, and the overall complication risk of malnourished patients compared with normal patients. The American College of Surgeons National Surgical Quality Improvement Program database was queried for TSA cases from 2005 to 2013 for this retrospective cohort study. Malnutrition was defined as preoperative albumin concentration of <3.5 g/dL. Rates of postoperative complications were compared between normal and malnourished patients. We identified 4,655 TSA cases, with preoperative albumin measurements available for 1681 patients (36.1%). Propensity score adjustment successfully reduced selection bias, with adjusted P values of >.05 for demographics, body mass index, and modified Charlson Comorbidity Index. Of the cohort with albumin measurements, 7.6% of patients were malnourished according to our criteria. Bivariate analysis showed malnourished patients had higher rates of pulmonary complications, anemia requiring transfusion, extended length of stay (LOS), and death (all P < .05). Propensity-adjusted multivariable logistic regression demonstrated that malnutrition was significantly associated (all P < .05) with postoperative transfusion (odds ratio, 2.49), extended LOS (odds ratio, 1.69), and death (odds ratio, 18.09). The overall prevalence of malnutrition was 7.6%. Malnourished patients were at a significantly increased risk for blood transfusion, longer hospital LOS, and death within 30 days of surgery. Multivariable analysis showed TSA patients with preoperative albumin levels of <3.5 g/dL are at much higher risk for morbidity and death after surgery than patients with albumin levels within normal reference ranges.

This retrospective study aimed to evaluate whether ultrasound texture analysis is useful to predict lymph node metastasis in patients with papillary thyroid microcarcinoma (PTMC). This study was approved by the Institutional Review Board, and the need to obtain informed consent was waived. Between May and July 2013, 361 patients (mean age, 43.8 ± 11.3 years; range, 16-72 years) who underwent staging ultrasound (US) and subsequent thyroidectomy for conventional PTMC ≤ 10 mm between May and July 2013 were included. Each PTMC was manually segmented and its histogram parameters (Mean, Standard deviation, Skewness, Kurtosis, and Entropy) were extracted with Matlab software. The mean values of histogram parameters and clinical and US features were compared according to lymph node metastasis using the independent t-test and Chi-square test. Multivariate logistic regression analysis was performed to identify the independent factors associated with lymph node metastasis. Tumors with lymph node metastasis (n = 117) had significantly higher entropy compared to those without lymph node metastasis (n = 244) (mean±standard deviation, 6.268±0.407 vs. 6.171±.0.405; P = .035). No additional histogram parameters showed differences in mean values according to lymph node metastasis. Entropy was not independently associated with lymph node metastasis on multivariate logistic regression analysis (Odds ratio, 0.977 [95% confidence interval (CI), 0.482-1.980]; P = .949). Younger age (Odds ratio, 0.962 [95% CI, 0.940-0.984]; P = .001) and lymph node metastasis on US (Odds ratio, 7.325 [95% CI, 3.573-15.020]; P < .001) were independently associated with lymph node metastasis. Texture analysis was not useful in predicting lymph node metastasis in patients with PTMC.

To describe the epidemiology of US emergency department (ED) visits for bronchiolitis, including the characteristics of children presenting to the ED and the variability in bronchiolitis care in the ED. Data were obtained from the 1992 to 2000 National Hospital Ambulatory Medical Care Survey. Cases had International Classification of Diseases, Ninth Revision, Clinical Modification code 466 and were younger than 2 years. National estimates were obtained using assigned patient visit weights; 95% confidence intervals were calculated using the relative standard error of the estimate; analysis used chi2 and logistic regression. From 1992 to 2000, bronchiolitis accounted for approximately 1,868,000 ED visits for children younger than 2 years. Among this same age group, the overall rate was 26 (95% confidence interval 22-31) per 1000 US population and 31 (95% confidence interval 26-36) per 1000 ED visits. These rates were stable over the 9-year period. Comparing children with bronchiolitis to those presenting with other problems, children with bronchiolitis were more likely boys (61% vs. 53%; P = 0.01) and Hispanic (27% vs. 20%; P = 0.008). Therapeutic interventions varied and 19% were admitted to the hospital. The multivariate predictor for receiving systemic steroids was urgent/emergent status at triage (odds ratio 4.0, 1.9-8.4). Multivariate predictors for admission were Hispanic ethnicity (odds ratio 2.3, 1.1-5.0) and urgent/emergent status at triage (odds ratio 3.7, 2.0-6.9). ED visit rates for bronchiolitis among children younger than 2 years were stable between 1992 and 2000. The observed ED practice variation demonstrates that children are receiving medications for which there is little supporting evidence. Boys and Hispanics are at-risk groups for presentation to the ED, and Hispanics are more likely to be hospitalized.

In European Ambulance Acute Coronary Syndrome Angiography (EUROMAX), bivalirudin improved 30-day clinical outcomes with reduced major bleeding compared with heparins plus optional glycoprotein IIb/IIIa inhibitors. We assessed whether choice of access site (radial or femoral) had an impact on 30-day outcomes and whether it interacted with the benefit of bivalirudin. In EUROMAX, choice of arterial access was left to operator discretion. Overall, 47% of patients underwent radial and 53% femoral access. Baseline risk was higher in the femoral access group. Unadjusted proportions for the primary outcome (death or noncoronary artery bypass graft protocol major bleeding at 30 days) were lower with radial access, however, without differences in major or major plus minor bleeding proportions. After multivariable adjustment, ischemic outcomes were no longer different between access site groups, except for a lower risk of stroke in radial patients. Bivalirudin was associated with lower proportions of the primary outcome in both the radial (odds ratio, 0.58; 95% CI, 0.33-1.03; P=0.058) and the femoral groups (odds ratio, 0.59; 95% CI, 0.37-0.93; P=0.022; interaction P=0.97). Bleeding was significantly lower in the bivalirudin group both in the radial- and femoral-treated patients but no significant difference was observed in ischemic outcomes. In multivariable analysis, bivalirudin emerged as the only independent predictor of reduced major bleeding (odds ratio, 0.45; 95% CI, 0.27-0.74; P=0.002). In this prespecified analysis from EUROMAX, radial access was preferred in lower risk patients and did not improve clinical outcomes. Bivalirudin was associated with less bleeding irrespective of access site. URL: http://www.clinicaltrials.gov. Unique identifier: NCT01087723. © 2015 American Heart Association, Inc.

Recent studies suggest an increased prevalence of chronic pain conditions and restless legs syndrome (RLS) in patients with chronic pulmonary disease (CPD). We analyzed the prevalence and risk factors for pain and RLS in a population-based sample of females with comorbid CPD. Questionnaire-based data from 2745 women aged 18-64 years were analyzed regarding comorbid CPD status (severe bronchitis, emphysema, asthma). Pain status was assessed according to symptoms reflecting severity (Visual Analogue Scale, VAS rating 0-10) and duration and spreading (limited spread or widespread) of pain. A diagnosis of RLS was defined by four validated diagnostic criteria. Anthropometrics and co-morbidities were assessed as covariates in univariate and multivariate analyses. Widespread pain was overrepresented in women with CPD (44.6 vs. 24.6%, p < 0.001). The odds ratio for widespread pain in women with CPD was 1.6 (95% confidence interval (CI) 1.2-2.2, p < 0.001) in the fully adjusted model. Severe pain (VAS rating ≥ 7) was more prevalent in females with known CPD (28.8 vs. 15.4%, p < 0.001, odd ratio 1.4 (95% CI 1.0-1.9, p = 0.029)). The prevalence of RLS was 37.4 and 23.8% in subjects with or without CPD, respectively (p < 0.001). In multivariate analysis, CPD was associated with a 30% risk increase for RLS (odds ratio 1.3 (95% CI 1.0-1.7, p = 0.04)). This population-based study identified CPD as an independent risk factor for severe and widespread pain as well as for RLS. Further research addressing pathophysiological mechanisms linking CPD and chronic pain conditions/RLS is warranted.

Purpose: Statins and anticoagulants (ACs) have both been associated with a less-aggressive prostate cancer (PCa) and a better outcome after treatment of localized PCa. The results of these studies might have been confounded because patients might often take both medications. We examined their respective influence on PCa aggressiveness at initial diagnosis. Materials and Methods: We analyzed 381 patients treated with either external beam radiotherapy or brachytherapy for low-risk (n = 152), intermediate-risk (n = 142), or high-risk (n = 87) localized PCa. Univariate and multivariate logistic regression analyses were used to investigate an association between these drug classes and prostatemore » cancer aggressiveness. We tested whether the concomitant use of statins and ACs had a different effect than that of either AC or statin use alone. Results: Of the 381 patients, 172 (45.1%) were taking statins and 141 (37.0%) ACs; 105 patients (27.6%) used both. On univariate analysis, the statin and AC users were associated with the prostate-specific antigen (PSA) level (p = .017) and National Comprehensive Cancer Network risk group (p = .0022). On multivariate analysis, statin use was associated with a PSA level <10 ng/mL (odds ratio, 2.9; 95% confidence interval, 1.3-6.8; p = .012) and a PSA level >20 ng/mL (odds ratio, 0.29; 95% confidence interval, 0.08-0.83; p = .03). The use of ACs was associated with a PSA level >20 ng/mL (odds ratio, 0.13; 95% confidence interval, 0.02-0.59, p = .02). Conclusion: Both AC and statins have an effect on PCa aggressiveness, with statins having a more stringent relationship with the PSA level, highlighting the importance of considering statin use in studies of PCa aggressiveness.« less

Objective: Infections are a major cause of morbidity and mortality in systemic lupus erythematosus. Clinical outcomes of systemic lupus erythematosus patients hospitalized due to infections vary among different ethnic populations. Thus, we determined the outcomes and associated factors in a group of Hispanics from Puerto Rico with systemic lupus erythematosus admitted due to severe infections. Methods: Records of systemic lupus erythematosus patients admitted to the Adult University Hospital, San Juan, Puerto Rico, from January 2006 to December 2014 were examined. Demographic parameters, lupus manifestations, comorbidities, pharmacologic treatments, inpatient complications, length of stay, readmissions, and mortality were determined. Patients with and without infections were compared using bivariate and multivariate analyses. Results: A total of 204 admissions corresponding to 129 systemic lupus erythematosus patients were studied. The mean (standard deviation) age was 34.7 (11.6) years; 90% were women. The main causes for admission were lupus flare (45.1%), infection (44.0%), and initial presentation of systemic lupus erythematosus (6.4%). The most common infections were complicated urinary tract infections (47.0%) and soft tissue infections (42.0%). In the multivariate analysis, patients admitted with infections were more likely to have diabetes mellitus (odds ratio: 4.20, 95% confidence interval: 1.23–14.41), exposure to aspirin prior to hospitalization (odds ratio: 4.04, 95% confidence interval: 1.03–15.80), and higher mortality (odds ratio: 6.00, 95% confidence interval: 1.01–35.68) than those without infection. Conclusion: In this population of systemic lupus erythematosus patients, 44% of hospitalizations were due to severe infections. Patients with infections were more likely to have diabetes mellitus and higher mortality. Preventive and control measures of infection could be crucial to improve survival in these patients.

Objective To use ecological momentary assessment techniques to measure the association of major depressive disorder (MDD) with media use. Design Data were collected using an ecological momentary assessment protocol with cellular telephone–based brief interviews. Setting Participants received as many as 60 telephone calls from a trained staff member during 5 extended week-ends in an 8-week period. Participants One hundred six adolescent participants who were part of a larger neurobehavioral study of depression in Pittsburgh from January 1, 2003, through December 31, 2008. Main Exposure At each call, participants were asked whether they were using the following 5 types of media: television or movies, music, video games, Internet, and print media, such as magazines, newspapers, and books. Main Outcome Measures We developed multivariable models to determine the independent association of each type of media use with MDD, controlling for socio-demographic variables. Results Of the 106 participants, 46 were diagnosed as having MDD. In multivariable models controlling for age, sex, and race, each increasing quartile of audio use was associated with an 80% increase in the odds of having MDD (odds ratio, 1.8; 95% confidence interval, 1.1–2.8; P = .01 for trend). Conversely, each increasing quartile of print media use was associated with a 48% decrease in the odds of having MDD (odds ratio, 0.5; 95% confidence interval, 0.3–0.9; P = .009 for trend). Conclusions Major depressive disorder is positively associated with popular music exposure and negatively associated with reading print media such as books. Further research elucidating the directionality and strength of these relationships may help advance understanding of the relationships between media use and MDD. PMID:21464384

Links between occupational exposures and morbidity in individuals with established chronic obstructive pulmonary disease (COPD) remain unclear. To determine the impact of occupational exposures on COPD morbidity. A job exposure matrix (JEM) determined occupational exposure likelihood based on longest job in current/former smokers (n = 1,075) recruited as part of the Subpopulations and Intermediate Outcomes in COPD Study, of whom 721 had established COPD. Bivariate and multivariate linear regression models estimated the association of occupational exposure with COPD, and among those with established disease, the occupational exposure associations with 6-minute-walk distance (6MWD), the Modified Medical Research Council Dyspnea Scale (mMRC), the COPD Assessment Test (CAT), St. George's Respiratory Questionnaire (SGRQ), 12-item Short-Form Physical Component (SF-12), and COPD exacerbations requiring health care utilization, adjusting for demographics, current smoking status, and cumulative pack-years. An intermediate/high risk of occupational exposure by JEM was found in 38% of participants. In multivariate analysis, those with job exposures had higher odds of COPD (odds ratio, 1.44; 95% confidence interval, 1.04-1.97). Among those with COPD, job exposures were associated with shorter 6MWDs (-26.0 m; P = 0.006); worse scores for mMRC (0.23; P = 0.004), CAT (1.8; P = 0.003), SGRQ (4.5; P = 0.003), and SF-12 Physical (-3.3; P < 0.0001); and greater odds of exacerbation requiring health care utilization (odds ratio, 1.55; P = 0.03). Accounting for smoking, occupational exposure was associated with COPD risk and, for those with established disease, shorter walk distance, greater breathlessness, worse quality of life, and increased exacerbation risk. Clinicians should obtain occupational histories from patients with COPD because work-related exposures may influence disease burden.

Esophageal adenocarcinoma (EA) is characterized by a strong male predominance. Sex steroid hormones have been hypothesized to underlie this sex disparity, but no population-based study to date has examined this potential association. Using mass spectrometry and ELISA, we quantitated sex steroid hormones and sex hormone binding globulin, respectively, in plasma from males- 172 EA cases and 185 controls-within the Factors Influencing the Barrett/Adenocarcinoma Relationship (FINBAR) Study, a case-control investigation conducted in Northern Ireland and Ireland. Multivariable adjusted logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for associations between circulating hormones and EA. Higher androgen:estrogen ratio metrics were associated with increased odds of EA (e.g., testosterone:estradiol ratio ORQ4 v. Q1 = 2.58, 95%CI = 1.23-5.43; Ptrend = 0.009). All estrogens and androgens were associated with significant decreased odds of EA. When restricted to individuals with minimal to no decrease in body mass index, the size of association for the androgen:estrogen ratio was not greatly altered. This first study of sex steroid hormones and EA provides tentative evidence that androgen:estrogen balance may be a factor related to EA. Replication of these findings in prospective studies is needed to enhance confidence in the causality of this effect.

Black women experience higher rates of hysterectomy than other women in the United States. Although research indicates that premenopausal hysterectomy with bilateral oophorectomy decreases the risk of breast cancer in black women, it remains unclear how hysterectomy without ovary removal affects risk, whether menopausal hormone therapy use attenuates inverse associations, and whether associations vary by cancer subtype. In the population-based, case-control Carolina Breast Cancer Study of invasive breast cancer in 1,391 black (725 cases, 666 controls) and 1,727 white (939 cases, 788 controls) women in North Carolina (1993–2001), we investigated the associations of premenopausal hysterectomy and oophorectomy with breast cancer risk. Compared with no history of premenopausal surgery, bilateral oophorectomy and hysterectomy without oophorectomy were associated with lower odds of breast cancer (for bilateral oophorectomy, multivariable-adjusted odds ratios = 0.60, 95% confidence interval: 0.47, 0.77; for hysterectomy without oophorectomy, multivariable-adjusted odds ratios = 0.68, 95% confidence interval: 0.55, 0.84). Estimates did not vary by race and were similar for hormone receptor–positive and hormone receptor–negative cancers. Use of estrogen-only menopausal hormone therapy did not attenuate the associations. Premenopausal hysterectomy, even without ovary removal, may reduce the long-term risk of hormone receptor–positive and hormone receptor–negative breast cancers. Varying rates of hysterectomy are a potentially important contributor to differences in breast cancer incidence among racial/ethnic groups. PMID:27555487

Previous research in the Nurses' Health Study (NHS) and the NHSII observed that, among women diagnosed with benign breast disease (BBD), those with predominant type 1/no type 3 lobules (a marker of complete involution) versus other lobule types were at lower risk of subsequent breast cancer. Studies in animal models suggest that insulin-like growth factor-1 (IGF-1) may inhibit involution of lobules in the breast; however, this has not been studied in humans. We conducted a cross-sectional study among 472 women in the NHSII who were diagnosed with biopsy-confirmed proliferative BBD between 1991 and 2002 and provided blood samples between 1996 and 1999. A pathologist, blinded to exposure status, classified lobule type in normal adjacent tissue on available biopsy slides according to the number of acini per lobule. For each participant, the pathologist determined the predominant lobule type (that is, type 1, type 2, or type 3) and whether any type 1 or any type 3 lobules were present. Lobule type was then classified as: predominant type 1/no type 3 lobules, which is suggestive of complete involution; or other lobule types. Multivariate logistic models were used to assess the associations between plasma IGF-1, insulin-like growth factor binding protein-3 (IGFBP-3), and the ratio of IGF-1:IGFBP-3 levels with lobule type. In univariate analyses, greater age, higher body mass index, postmenopausal status, nulliparity, and lower IGF-1 levels were associated with predominant type 1/no type 3 lobules (P < 0.05). In multivariate models adjusting for age and assay batch, higher IGF-1 levels were associated with decreased odds of predominant type 1/no type 3 lobules (odds ratio quartile 4 vs. quartile 1 = 0.37, 95% confidence interval = 0.15 to 0.89). Greater ratios of IGF-1:IGFBP-3 levels were also associated with decreased odds of predominant type 1/no type 3 lobules (odds ratio quartile 4 vs. quartile 1 = 0.26, 95% confidence interval = 0.11 to 0.64). These results were slightly attenuated after adjustment for other potential predictors of lobule type. Higher IGF-1 levels and a greater IGF-1:IGFBP-3 ratio were associated with decreased odds of having predominant type 1 lobules/no type 3 lobules among women with proliferative BBD in the NHSII. This study provides further evidence for the role of insulin-like growth factors in the structure of breast lobules and lobular involution.

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.

Between 1 April 2012 and 31 March 2015, 263 of the 2244 families in the UK whose loved ones had registered to donate organs for transplantation after their death on the NHS Organ Donor Register chose to override this decision; an override rate of 11.7%. Multivariable logistic regression analysis was applied to data relating to various aspects of the family approach in order to identify factors associated with such overrides. The factors associated with family overrides were failure to involve the Specialist Nurse for Organ Donation in the family approach (odds ratio 3.0), donation after circulatory death (odds ratio 2.7) and Black, Asian or Minority Ethnicity (odds ratio 2.7). This highlights the need to further engage with these groups in exploring donation as an end of life choice, and suggests that there may be, from the perspective of the family, fundamental differences between donation after brainstem death and circulatory death. It further adds to the body of data linking involvement of the Specialist Nurse for Organ Donation in the family approach to improved UK consent rates.

To assess factors that predict good tolerance of noninvasive ventilation (NIV), in order to improve survival and quality of life in subjects with amyotrophic lateral sclerosis. We conducted a prospective study in subjects with amyotrophic lateral sclerosis and requiring NIV. The primary end point was NIV tolerance at 1 month. Subjects, several of whom failed to complete the study, were classified as "tolerant" or "poorly tolerant," according to the number of hours of NIV use (more or less than 4 h per night, respectively). Eighty-one subjects, 73 of whom also attended the 1-month follow-up visit, participated over 34 months. NIV tolerance after the first day of utilization predicted tolerance at 1 month (77.6% and 75.3% of subjects, respectively). Multivariate analysis disclosed 3 factors predicting good NIV tolerance: absence of airway secretions accumulation prior to NIV onset (odds ratio 11.5); normal bulbar function at initiation of NIV (odds ratio 8.5); and older age (weakly significant, odds ratio 1.1). Our study reveals 3 factors that are predictive of good NIV tolerance, in particular the absence of airway secretion accumulation, which should prompt NIV initiation before its appearance.

Carbapenems are commonly used in hospitalized infants despite a lack of complete safety data and associations with seizures in older children. We compared the incidence of adverse events in hospitalized infants receiving meropenem versus imipenem/cilastatin. We conducted a retrospective cohort study of 5566 infants treated with meropenem or imipenem/cilastatin in neonatal intensive care units managed by the Pediatrix Medical Group between 1997 and 2010. Multivariable conditional logistic regression was performed to evaluate the association between carbapenem therapy and adverse events, controlling for infant factors and severity of illness. Adverse events were more common with use of meropenem compared with imipenem/cilastatin (62.8/1000 infant days versus 40.7/1000 infant days, P < 0.001). There was no difference in seizures with meropenem versus imipenem/cilastatin (adjusted odds ratio 0.96; 95% confidence interval: 0.68, 1.32). The incidence of death, as well as the combined outcome of death or seizure, was lower with meropenem use-odds ratio 0.68 (0.50, 0.88) and odds ratio 0.77 (0.62, 0.95), respectively. In this cohort of infants, meropenem was associated with more frequent but less severe adverse events when compared with imipenem/cilastatin.

To evaluate the association between migraine and body composition status as estimated based on body mass index and WHO physical status categories. Systematic electronic database searches were conducted for relevant studies. Two independent reviewers performed data extraction and quality appraisal. Odds ratios (OR) and confidence intervals (CI) were pooled using a random effects model. Significant values, weighted effect sizes, and tests of homogeneity of variance were calculated. A total of 12 studies, encompassing data from 288,981 unique participants, were included. The age- and sex-adjusted pooled risk of migraine in those with obesity was increased by 27% compared with those of normal weight (odds ratio [OR] 1.27; 95% confidence interval [CI] 1.16-1.37, p < 0.001) and remained increased after multivariate adjustments. Although the age- and sex-adjusted pooled migraine risk was increased in overweight individuals (OR 1.08; 95% CI 1.04, 1.12, p < 0.001), significance was lost after multivariate adjustments. The age- and sex-adjusted pooled risk of migraine in underweight individuals was marginally increased by 13% compared with those of normal weight (OR 1.13; 95% CI 1.02, 1.24, p < 0.001) and remained increased after multivariate adjustments. The current body of evidence shows that the risk of migraine is increased in obese and underweight individuals. Studies are needed to confirm whether interventions that modify obesity status decrease the risk of migraine. © 2017 American Academy of Neurology.

Some published evidence has revealed that the dendritic cells can interact with pathogens that exist in the inner foreskin. This information provides a new vision that pathogens could play a role through the redundant prepuce; numerous studies have failed to find pathogens in prostates of patients who had chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). However, no studies have reported an association between foreskin length and CP/CPPS. Hence, we conducted a retrospective case-control study of clinical data from 322 CP/CPPS patients (case group) and 341 nonCP/CPPS patients (control group). Demographic characteristics, lifestyle factors, and foreskin lengths were collected and analyzed. Multivariate logistic regression was adopted to calculate the odds of foreskin length for CP/CPPS. According to the multivariate logistic regression results, when the foreskin length covered up more than half of the glans penis, the odds for CP/CPPS were higher with an increased foreskin (odds ratio (OR): 1.66, 95% confidence interval (CI): 1.04-2.66). In comparison, when the glans penis was completely covered by the foreskin, the OR value increased to 1.86 (95% CI, 1.2-2.88). The study results showed an association between foreskin length and the odds of CP/CPPS. When the foreskin length covered up more than half of the glans penis, there were greater odds for CP/CPPS. This possible mechanism might result from interaction between pathogens and DCs in the inner foreskin, consequently activating T-cells to mediate allergic inflammation in the prostate and producing the autoimmunizations causing CP/CPPS.

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.

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.

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 purpose of this study was to develop a multivariate fall risk assessment model beyond the current fall Resident Assessment Protocol (RAP) triggers for nursing home residents using the Minimum Data Set (MDS). Retrospective, clustered secondary data analysis. National Veterans Health Administration (VHA) long-term care nursing homes (N = 136). The study population consisted of 6577 national VHA nursing home residents who had an annual assessment during FY 2005, identified from the MDS, as well as an earlier annual or admission assessment within a 1-year look-back period. A dichotomous multivariate model of nursing home residents coded with a fall on selected fall risk characteristics from the MDS, estimated with general estimation equations (GEE). There were 17 170 assessments corresponding to 6577 long-term care nursing home residents. The increased odds ratio (OR) of being classified as a faller relative to the omitted "dependent" category of activities of daily living (ADL) ranged from OR = 1.35 for "limited" ADL category up to OR = 1.57 for "extensive-2" ADL (P < .0001). Unsteady gait more than doubles the odds of being a faller (OR = 2.63, P < .0001). The use of assistive devices such as canes, walkers, or crutches, or the use of wheelchairs increases the odds of being a faller (OR = 1.17, P < .0005) or (OR = 1.19, P < .0002), respectively. Foot problems may also increase the odds of being a faller (OR = 1.26, P < .0016). Alzheimer's or other dementias also increase the odds of being classified as a faller (OR = 1.18, P < .0219) or (OR=1.22, P < .0001), respectively. In addition, anger (OR = 1.19, P < .0065); wandering (OR = 1.53, P < .0001); or use of antipsychotic medications (OR = 1.15, P < .0039), antianxiety medications (OR = 1.13, P < .0323), or antidepressant medications (OR = 1.39, P < .0001) was also associated with the odds of being a faller. This national study in one of the largest managed healthcare systems in the United States has empirically confirmed the relative importance of certain risk factors for falls in long-term care settings. The model incorporated an ADL index and adjusted for case mix by including only long-term care nursing home residents. The study offers clinicians practical estimates by combining multiple univariate MDS elements in an empirically based, multivariate fall risk assessment model.

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.

Inadequate nutrition during the first two years of life may lead to childhood morbidity and mortality, as well as inadequate brain development. Infants are at increased risk of malnutrition by six months, when breast milk alone is no longer sufficient to meet their nutritional requirements. However the factors associated with nutritional status of infants after 6 months of age have received little attention in pastoralist communities of Ethiopia. Therefore this study aimed to identify the factors associated with nutritional status of infants and young children (6-23 months) in Filtu town, Somali Region, Ethiopia. A cross-sectional community-based study was conducted. Simple random sampling was employed to select 214 infants for the study. Univariable and multivariable logistic regressions models were used in the statistical analysis. The strength of association was measured by odds ratios with 95% confidence intervals. Both the crude (COR) and adjusted odds ratios (AOR) are reported. The prevalence of wasting, stunting and underweight among infants and young children were 17.5% (95% CI: 12.91-23.22), 22.9% (95% CI: 17.6-28.9) and 19.5% (95% CI: 14.58-25.3) respectively. The multivariable logistic regression model showed that breastfeeding was independently associated with reduced odds of wasting (AOR = 0.38(95% CI: 0.14-0.99)). Diarrhea in the past 15 days (AOR = 2.13 (95% CI: 1.55-4.69)) was also associated with increased odds for wasting. The independent predictors of reduced odds for stunting were dietary diversity score ≥ 4 (AOR = 0.45(95% CI: 0.21-0.95)) and introduction of complementary feeding at 6 months (AOR = 0.25 (95% CI: 0.09-0.66)). Bottle feeding was associated with increased odds of stunting (AOR = 3.83 (95% CI: 1.69-8.67)). Breastfeeding was associated with reduced odds of underweight (AOR = 0.24 (95% CI: 0.1-0.59)), while diarrheal disease in the past 15 days was associated with increased odds of underweight (AOR = 3.54 (95% CI: 1.17-7.72)). Under nutrition is a public health problem among infants and young children in Filtu town, Somali region Ethiopia. Breastfeeding was associated with lower odds of wasting and underweight while diarrheal disease was associated with higher odds of wasting and underweight. Low dietary diversity scores, inappropriate age of complementary feeding initiation and bottle feeding were identified to be significant predictors of stunting. Those factors should be considered for any intervention aimed to reduce under nutrition among infants and young children in Filitu town, Somali region, Ethiopia.

Despite previously found co-occurrence of youth gambling and alcohol use, their relationship has not been systematically explored in a national sample using DSM-based gambling measures and multivariate modeling, adjusted for potential confounders. This study aimed to empirically examine the prevalence patterns and odds of at-least-weekly alcohol use and heavy episodic drinking (HED) in relation to various levels of gambling severity in college athletes. Multivariate logistic regression analyses were performed on data from a national sample of 20,739 U.S. college athletes from the first National Collegiate Athletic Association national survey of gambling and health-risk behaviors. Prevalence of at-least-weekly alcohol use significantly increased as DSM-IV-based gambling severity increased, from non-gambling (24.5%) to non-problem gambling (43.7%) to sub-clinical gambling (58.5%) to problem gambling (67.6%). Multivariate results indicated that all levels of gambling were associated with significantly elevated risk of at-least-weekly HED, from non-problem (OR = 1.25) to sub-clinical (OR = 1.75) to problem gambling (OR = 3.22); the steep increase in the relative risk also suggested a possible quadratic relationship between gambling level and HED risk. Notably, adjusted odds ratios showed problem gambling had the strongest association with at-least-weekly HED, followed by marijuana (OR = 3.08) and cigarette use (OR = 2.64). Gender interactions and differences were also identified and assessed. In conclusion, attention should be paid to college athletes exhibiting gambling problems, especially considering their empirical multivariate associations with high-risk drinking; accordingly, screening for problem gambling is recommended. More research is warranted to elucidate the etiologic mechanisms of these associations. Copyright © 2010 Elsevier Ltd. All rights reserved.

Although a higher prevalence of osteoarthritis (OA) has been reported among diabetes mellitus (DM) patients, inconsistencies and limitations of observational studies have precluded a conclusive association. The objective of this study was to evaluate the association of hand or knee OA with DM in a population of Hispanics from Puerto Rico. A cross-sectional study was performed in 202 subjects (100 adult DM patients as per the National Diabetes Data Group Classification and 102 nondiabetic subjects). Osteoarthritis of hand and knee was ascertained using the American College of Rheumatology classification criteria. Sociodemographic characteristics, health-related behaviors, comorbidities, pharmacotherapy, and DM clinical manifestations were determined. Multivariable logistic regression was used to evaluate the association of DM with hand or knee OA and to evaluate factors associated with hand or knee OA among DM patients. The mean (SD) age for DM patients was 51.6 (13.1) years; 64.0% were females. The mean (SD) DM duration was 11.0 (10.4) years. The prevalence of OA in patients with DM and nondiabetic subjects was 49.0% and 26.5%, respectively (P < 0.01). In the multivariable analysis, patients with DM had 2.18 the odds of having OA when compared with nondiabetic subjects (95% confidence interval [CI], 1.12-4.24). In a subanalysis among DM patients, female patients were more likely to have hand or knee OA (odds ratio [95% CI], 5.06 [1.66-15.66]), whereas patients who did not use insulin alone for DM therapy were more likely to have OA (odds ratio [95% CI], 4.44 [1.22-16.12]). In this population of Hispanics from Puerto Rico, DM patients were more likely to have OA of hands or knees than were nondiabetic subjects. This association was retained in multivariable models accounting for established risk factors for OA. Among DM patients, females were at greater risk for OA, whereas the use of insulin was negatively associated.

Psoriasis has been shown to be associated with cardiovascular disease in adults. Little is known about cardiovascular risk in pediatric psoriasis. To determine if there is an association between pediatric psoriasis and cardiovascular comorbidities. Data were analyzed from the 2002-2012 Nationwide Inpatient Sample, which included 4,884,448 hospitalized children aged 0-17 years. Bivariate and multivariate survey logistic regression models were created to calculate the odds of psoriasis on cardiovascular comorbidities. In multivariate survey logistic regression models adjusting for age, sex, and race/ethnicity, pediatric psoriasis was significantly associated with 5 of 10 cardiovascular comorbidities (adjusted odds ratio [95% confidence interval]), including obesity (3.15 [2.46-4.05]), hypertension (2.63 [1.93-3.59]), diabetes (2.90 [1.90-4.42]), arrhythmia (1.39 [1.02-1.88]), and valvular heart disease (1.90 [1.07-3.37]). The highest odds of cardiovascular risk factors occurred in blacks and Hispanics and children ages 0-9 years, but there were no sex differences. The study was limited to hospitalized children. We were unable to assess the impact of psoriasis treatment or family history on cardiovascular risk. Pediatric psoriasis is associated with higher odds of multiple cardiovascular comorbidities among hospitalized patients. Strategies for mitigating excess cardiovascular risk in pediatric psoriasis need to be determined. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.

Objectives Preexposure prophylaxis (PREP) is an emerging HIV prevention strategy; however, many fear it may lead to neglect of traditional risk reduction practices through behavioral disinhibition or risk compensation. Methods Participants were 180 HIV-negative high-risk men who have sex with men recruited in New York City, who completed an Audio Computer Assisted Self Interview-administered survey between September 2007 and July 2009. Bivariate and multivariate logistic regression models were used to predict intention to use PREP and perceptions that PREP would decrease condom use. Results Almost 70% (n = 124) of participants reported that they would be likely to use PREP if it were at least 80% effective in preventing HIV. Of those who would use PREP, over 35% reported that they would be likely to decrease condom use while on PREP. In multivariate analyses, arousal/pleasure barriers to condom use significantly predicted likelihood of PREP use (odds ratio = 1.71, P < 0.05) and risk perception motivations for condom use significantly predicted decreased condom use on PREP (odds ratio = 2.48, P < 0.05). Discussion These data provide support for both behavioral disinhibition and risk compensation models and underscore the importance of developing behavioral interventions to accompany any wide-scale provision of PREP to high-risk populations.

Both low serum calcium and magnesium levels have been associated with the extent of bleeding in patients with intracerebral hemorrhage, suggesting hypocalcemia- and hypomagnesemia-induced coagulopathy as a possible underlying mechanism. We hypothesized that serum albumin-corrected total calcium and magnesium levels are associated with ruptured intracranial aneurysms. The medical records of 4701 patients, including 1201 prospective patients, diagnosed at the Brigham and Women's Hospital and Massachusetts General Hospital between 1990 and 2016 were reviewed and analyzed. One thousand two hundred seventy-five patients had available serum calcium, magnesium, and albumin values within 1 day of diagnosis. Individuals were divided into cases with ruptured aneurysms and controls with unruptured aneurysms. Univariable and multivariable logistic regression analyses were performed to determine the association between serum albumin-corrected total calcium and magnesium levels and ruptured aneurysms. In multivariable analysis, both albumin-corrected calcium (odds ratio, 0.33; 95% confidence interval, 0.27-0.40) and magnesium (odds ratio, 0.40; 95% confidence interval, 0.28-0.55) were significantly and inversely associated with ruptured intracranial aneurysms. In this large case-control study, hypocalcemia and hypomagnesemia at diagnosis were significantly associated with ruptured aneurysms. Impaired hemostasis caused by hypocalcemia and hypomagnesemia may explain this association. © 2018 American Heart Association, Inc.

Previous studies have suggested a protective effect of diabetes mellitus on aneurysmal subarachnoid hemorrhage risk. However, reports are inconsistent, and objective measures of hyperglycemia in these studies are lacking. Our aim was to investigate the association between aneurysmal subarachnoid hemorrhage and antihyperglycemic agent use and glycated hemoglobin levels. The medical records of 4701 patients with 6411 intracranial aneurysms, including 1201 prospective patients, diagnosed at the Massachusetts General Hospital and Brigham and Women's Hospital between 1990 and 2016 were reviewed and analyzed. Patients were separated into ruptured and nonruptured groups. Univariate and multivariate logistic regression analyses were performed to determine the association between aneurysmal subarachnoid hemorrhage and antihyperglycemic agents and glycated hemoglobin levels. Propensity score weighting was used to account for selection bias. In both unweighted and weighted multivariate analysis, antihyperglycemic agent use was inversely and significantly associated with ruptured aneurysms (unweighted odds ratio, 0.58; 95% confidence interval, 0.39-0.87; weighted odds ratio, 0.57; 95% confidence interval, 0.34-0.96). In contrast, glycated hemoglobin levels were not significantly associated with rupture status. Antihyperglycemic agent use rather than hyperglycemia is associated with decreased risk of aneurysmal subarachnoid hemorrhage, suggesting a possible protective effect of glucose-lowering agents in the pathogenesis of aneurysm rupture. © 2017 American Heart Association, Inc.

This work aims to study the associations, if any, of hyperuricemia, gout, and menopause status in the US population. Using multiyear data from the National Health and Nutrition Examination Survey, we performed unmatched comparisons and one to three age-matched comparisons of women aged 20 to 70 years with and without hyperuricemia (serum urate ≥6 mg/dL). Analyses were performed using survey-weighted multiple logistic regression and conditional logistic regression, respectively. Overall, there were 1,477 women with hyperuricemia. Age and serum urate were significantly correlated. In unmatched analyses (n = 9,573 controls), postmenopausal women were older, were heavier, and had higher prevalence of renal impairment, hypertension, diabetes, and hyperlipidemia. In multivariable regression, after accounting for age, body mass index, glomerular filtration rate, and diuretic use, menopause was associated with hyperuricemia (odds ratio, 1.36; 95% CI, 1.05-1.76; P = 0.002). In corresponding multivariable regression using age-matched data (n = 4,431 controls), the odds ratio for menopause was 0.94 (95% CI, 0.83-1.06). Current use of hormone therapy was not associated with prevalent hyperuricemia in both unmatched and matched analyses. Age is a better statistical explanation for the higher prevalence of hyperuricemia among older women than menopause status.

Objective Epidermal growth factor receptor inhibitors can result in a severe rash in 5–10% of patients and can detract from quality of life. The objective of this study was to identify clinical predictors of severe rash in the hope of utilizing such factors in the design of future rash palliative and prevention trials. Methods 933 cetuximab-treated patients enrolled on N0147, an adjuvant chemotherapy trial for colon cancer, were evaluated for clinical risk factors of severe rash. Results Within this cohort, 50 patients (5%) developed a severe rash (grade 3). More men compared to women developed such a rash: 34 (7%) versus 16 (3%) (multivariate odds ratio = 2.12; 95% confidence interval: 1.14–3.88; p = 0.017). A greater number of younger patients (<70 years of age) also developed a rash: 48 (6%) versus 2 (1%) (multivariate odds ratio = 0.21; 95% confidence interval: 0.05–0.88; p = 0.032). Race and performance score were not predictive. Conclusion Men and younger patients are at greater risk for a severe cetuximab-induced rash although overall the risk is low. These observations are particularly important in designing future rash prevention and palliation trials. PMID:19622902

To determine the prevalence of helminth infestation during pregnancy and the associated risks of adverse maternal and infant outcomes. A cross-sectional study of women with a singleton pregnancy of at least 34 weeks was conducted at a teaching hospital in Benin City, Nigeria, between April 1 and September 30, 2010. Socioeconomic and clinical data were obtained. Stool samples were used to determine helminth infection. Birth weight was recorded at delivery. Multivariable analysis was used to assess the link between helminth infestation and maternal and perinatal outcomes. Among 178 women, 31 (17.4%) had a helminth infestation (15 [8.4%] had ascariasis, 8 [4.5%] trichuriasis, and 25 [14.0%] hookworm infestation). Multivariate analysis found that helminth infestations was associated with maternal anemia (adjusted odds ratio 12.4; 95% confidence interval 4.2-36.3) and low birth weight (adjusted odds ratio 6.8; 95% confidence interval 2.1-21.9). Approximately one in five women had a helminth infestation in the third trimester of pregnancy. Maternal helminth infestation significantly increased the risks of maternal anemia and low birth weight, indicating that routine administration of anthelminthic drugs during early pregnancy might improve perinatal outcomes.

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.

BACKGROUND Patients are frequently discharged with central venous catheters (CVCs) for home infusion therapy. OBJECTIVE To study a prospective cohort of patients receiving home infusion therapy to identify environmental and other risk factors for complications. DESIGN Prospective cohort study between March and December 2015. SETTING Home infusion therapy after discharge from academic medical centers. PARTICIPANTS Of 368 eligible patients discharged from 2 academic hospitals to home with peripherally inserted central catheters and tunneled CVCs, 222 consented. Patients remained in the study until 30 days after CVC removal. METHODS Patients underwent chart abstraction and monthly telephone surveys while the CVC was in place, focusing on complications and environmental exposures. Multivariable analyses estimated adjusted odds ratios and adjusted incident rate ratios between clinical, demographic, and environmental risk factors and 30-day readmissions or CVC complications. RESULTS Of 222 patients, total parenteral nutrition was associated with increased 30-day readmissions (adjusted odds ratio, 4.80 [95% CI, 1.51–15.21) and CVC complications (adjusted odds ratio, 2.41 [95% CI, 1.09–5.33]). Exposure to soil through gardening or yard work was associated with a decreased likelihood of readmissions (adjusted odds ratio, 0.09 [95% CI, 0.01–0.74]). Other environmental exposures were not associated with CVC complications. CONCLUSIONS complications and readmissions were common and associated with the use of total parenteral nutrition. Common environmental exposures (well water, cooking with raw meat, or pets) did not increase the rate of CVC complications, whereas soil exposures were associated with decreased readmissions. Interventions to decrease home CVC complications should focus on total parenteral nutrition patients. PMID:27697084

A self-reported measure of four domains of work impairment based on the Work Limitations Questionnaire was completed by 16,651 employees of a large financial services corporation. Using a multivariate model to control for coexisting conditions, age, and gender, significant relationships were observed between medical conditions and patterns of impaired work performance. Depression was highly associated with work limitations in time management (odds ratio [OR] = 2.05), interpersonal/mental functioning (OR = 2.50), and overall output (OR = 2.24). Arthritis (OR = 1.56) and low back pain (OR = 1.32) were associated with physical function limitations. These same two conditions were associated with limitations in mental/interpersonal functioning but with low back pain having the higher odds ratio (OR = 1.54 vs. 1.22). These results suggest that worksite interventions (eg, disease management programs) should be tailored to the unique effects observed with specific medical conditions. More targeted programs could have important benefits for productivity in the workplace.

To determine the association between antenatal steroids administration and intraventricular hemorrhage rates. We used cross-sectional data from the California Perinatal Quality Care Collaborative during 2007 to 2013 for infants ⩽32 weeks gestational age. Using multivariable logistic regression, we evaluated the effect of antenatal steroids on intraventricular hemorrhage, stratified by gestational age. In 25 979 very-low-birth weight infants, antenatal steroid use was associated with a reduction in incidence of any grade of intraventricular hemorrhage (odds ratio=0.68, 95% confidence interval: 0.62, 0.75) and a reduction in incidence of severe intraventricular hemorrhage (odds ratio=0.51, 95% confidence interval: 0.45, 0.58). This association was seen across gestational ages ranging from 22 to 29 weeks. Although current guidelines recommend coverage for preterm birth at 24 to 34 weeks gestation, our results suggest that treatment with antenatal steroids may be beneficial even before 24 weeks of gestational age.

Nurse Satisfaction With Opportunities to Engage in Research.

PubMed

Hagan, Joseph

2018-02-01

Nurses should be able to participate in research and integrate evidence from research into practice; however, studies investigating factors related to nurse satisfaction with opportunities to engage in research are lacking. A questionnaire was distributed to nurses employed at two sites: a hospital and a nursing school. Only 16% of nurses reported being satisfied with opportunities to engage in research. In multivariate analysis, degree of belief that resources are a barrier to research was inversely proportional to satisfaction with nursing research opportunities (adjusted odds ratio = 0.13, p < .001), whereas perception that personal relevance is a barrier to research was associated with increased satisfaction (adjusted odds ratio = 2.38, p < .001). Satisfaction with opportunities to engage in research is low. Incentivizing nursing research and providing protected research time, training and education, and mentors to guide nurses through the research process could be effective strategies for increasing satisfaction and research productivity, thereby strengthening evidence-based practice.

Shift work is associated with health problems, including metabolic syndrome. This study investigated the association between shift work and metabolic syndrome in young workers. A total of 3,317 subjects aged 20-40 years enrolled in the 2011-2012 Korean National Health and Nutrition Examination Survey were divided into shift and day workers. We conducted a cross-sectional study and calculated odds ratios using multivariate logistic regression analysis in order to examine the association between shift work and metabolic syndrome. The prevalence of metabolic syndrome was 14.3% and 7.1% among male and female shift workers, respectively. After adjusting for confounding factors, shift work was associated with metabolic syndrome in female workers (odds ratio, 2.53; 95% confidence interval, 1.12 to 5.70). Shift work was associated with metabolic syndrome in young women. Timely efforts are necessary to manage metabolic syndrome in the workplace.

To investigate the risk factors associated with candida infection of the genital tract in the tropics. We performed questionnaire survey and experiments at the Hainan branch of General Hospital of People's Liberation Army, Hainan General Hospital and Sanya Maternity and Child Health Care Hospital in 2013. Controls were without Candida infection of genital tract, and cases had from Candida infection. We recruited 689 cases and 652 controls. The average age of cases with Candida infection of the genital tract was higher than that of controls. In the multivariate modeling, marriage (adjusted odds ratio: 2.49, 95% confidential interval: 1.09-5.67) and vaginal lavage (adjusted odds ratio: 4.41, 95% confidential interval: 1.13-5.14) were significantly associated with Candida infection of genital tract in tropics. Candida infection was related with age. Marriage and Vaginal lavage were significant risk factors. Attention should be paid to health education for the prevention of these infections.

Extensive resection for hilar cholangiocarcinoma is the most effective treatment, but high morbidity and poor prognosis remain concerns. Previous data have shown marked differences in outcomes between comparable Eastern and Western centers. We compared the outcomes of the management for hilar cholangiocarcinoma at one Japanese and one British institution with comparable experience. Of 298 consecutive patients with hilar cholangiocarcinoma evaluated at Hirosaki University Hospital, Japan and St. James's University Hospital, Leeds, UK, 183 underwent radical resection. Clinicopathologic variables and postoperative outcomes were compared. Significant differences were not observed between the Hirosaki and Leeds cohorts in overall outcomes despite several differences in the patient characteristics. Although there was a difference in 90-day mortality (2.5% vs 13.6%, respectively), disease-specific 5-year survival rates were 32.8% and 31.9%, respectively (P = .767). Multivariate analysis identified trisectionectomy (odds ratio = 2.32; P = .010), combined pancreatoduodenectomy (odds ratio = 7.88; P = .010), and perioperative blood transfusion (odds ratio = 1.88; P = .045) were associated with postoperative major complications, while preoperative biliary drainage associated with postoperative major complications, while preoperative biliary drainage (risk ratio = 2.21; P = .018), perioperative blood transfusion (risk ratio = 1.58; P = .029), lymph node metastasis (risk ratio = 2.00; P = .002), moderate/poorly differentiated tumor (risk ratio = 1.72; P = .029), microvascular invasion (risk ratio = 1.63; P = .046), and R1 resection (risk ratio = 1.90; P = .005) were risk factors for poor survival. Disease-specific survival and prognostic factors were similar in both centers. Meticulous operative technique to avoid perioperative blood transfusion may improve long-term survival.

Summary Introduction. Smoking tobacco during pregnancy is a preventable risk factor for adverse pregnancy outcomes. The aim of the study was to assess the impact of an information and training program implemented by the perinatal network of Auvergne, France, on smoking during pregnancy. Methods. A multi-center before-and-after population-based study, based on two cross-sectional surveys, was carried out between July 2003 and June 2004, and between December 2008 and January 2010. Pregnant women aged over 18 years, with a fluent command of written and spoken French, were eligible. The main outcome was the prevalence of pregnant women who smoked daily. The preventive program consisted of informing women and healthcare providers and training healthcare providers. Multivariate analysis was performed by means of manual logistic regression and crude and adjusted Odds Ratios were calculated. Findings. "Before" and "after" surveys involved 1027 and 720 women, respectively. In the "after" survey, a higher percentage of women smoked daily at the time of diagnosis (43.49% vs 51.94%, adjusted Odds Ratio 1.45 [1.10; 1.90]) and during the third term (40.53% vs 51.94%, adjusted Odds Ratio 1.62 [1.24; 2.12]). Environmental tobacco smoke exposure among non-smokers was higher in the "after" survey: 52.83% vs 69.57% adjusted Odds Ratio 1.95 [1.54; 2.47]. Conclusions. The program did not reduce smoking during pregnancy. Exposure to environmental tobacco smoke increased. French public health authorities should introduce a new policy aimed specifically at tackling tobacco use during pregnancy and exposure to second-hand smoke, and which takes into account the entire environment of pregnant women.

Sleep disorders and depression/anxiety disorders are long-standing and significant problem for mental health. Also there are already known so many negative health effect of these disorders. But there were few studies to examine the association between activities outside work and forementioned disorders. So this study aimed the association of those things by using the Republic of Korean data. Data from 32,232 wage workers were used in the 4th Korean Working Condition Survey. General and occupational characteristics, sleep disorders, depression/anxiety disorders and activities outside work are included in questionnaire. To find the relationship between activities outside work and sleep, depression/anxiety disorders, multivariate logistic regression analysis was used after adjusting for general and occupational characteristics. We observed that volunteer activities increased the odds ratio of both sleep disorders and depression/anxiety disorders(Odds ratio[OR] = 1.35, 95% confidence interval[CI]: 1.03-1.78 and OR = 1.54, 95% CI: 1.29-1.84, respectively). And self-development activities increase the odds ratio of sleep disorders(OR = 1.35, 95% CI: 1.17-1.57). Gardening activities lowered the odds ratio of depression/anxiety disorders(OR = 0.74, 95% CI: 0.59-0.94). Some of activities outside work were related to sleep disorders and depression/anxiety disorders among Korean wage workers. Our results showed negative health effect of some kinds of activities outside work such as volunteering and self-devlopment compared to other studies that emphasized positive effect of those activities for health.

The intracerebral hemorrhage (ICH) score is the most commonly used grading scale for stratifying functional outcome in patients with acute ICH. We sought to determine whether a combination of the ICH score and the computed tomographic angiography spot sign may improve outcome prediction in the cohort of a prospective multicenter hemorrhage trial. Prospectively collected data from 241 patients from the observational PREDICT study (Prediction of Hematoma Growth and Outcome in Patients With Intracerebral Hemorrhage Using the CT-Angiography Spot Sign) were analyzed. Functional outcome at 3 months was dichotomized using the modified Rankin Scale (0-3 versus 4-6). Performance of (1) the ICH score and (2) the spot sign ICH score-a scoring scale combining ICH score and spot sign number-was tested. Multivariable analysis demonstrated that ICH score (odds ratio, 3.2; 95% confidence interval, 2.2-4.8) and spot sign number (n=1: odds ratio, 2.7; 95% confidence interval, 1.1-7.4; n>1: odds ratio, 3.8; 95% confidence interval, 1.2-17.1) were independently predictive of functional outcome at 3 months with similar odds ratios. Prediction of functional outcome was not significantly different using the spot sign ICH score compared with the ICH score alone (spot sign ICH score area under curve versus ICH score area under curve: P =0.14). In the PREDICT cohort, a prognostic score adding the computed tomographic angiography-based spot sign to the established ICH score did not improve functional outcome prediction compared with the ICH score. © 2018 American Heart Association, Inc.

To study whether preconceptual thyroid-stimulating hormone (TSH) and antithyroid peroxidase (TPO) antibodies are associated with poor reproductive outcomes in infertile women. Secondary analysis of data from two multicenter, randomized, controlled trials conducted by the Reproductive Medicine Network of the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Multivariable logistic regression analyses were performed to assess the association between preconceptual TSH levels and anti-TPO antibodies. Not applicable. Serum samples from 1,468 infertile women were utilized. None. Cumulative conception, clinical pregnancy, miscarriage, and live birth rates were calculated. Conception, clinical pregnancy, miscarriage, and live birth rates did not differ between patients with TSH ≥2.5 mIU/L vs. TSH < 2.5 mIU/L. Women with anti-TPO antibodies had similar conception rates (33.3% vs. 36.3%) but higher miscarriage rates (43.9% vs. 25.3%) and lower live birth rates (17.1% vs. 25.4%) than those without anti-TPO antibodies. Adjusted, multivariable logistic regression models confirmed elevated odds of miscarriage (odds ratio 2.17, 95% confidence interval 1.12-4.22) and lower odds of live birth (oddr ratio 0.58, 95% confidence interval 0.35-0.96) in patients with anti-TPO antibodies. In infertile women, preconceptional TSH ≥2.5 mIU/L is not associated with adverse reproductive outcomes; however, anti-TPO antibodies are associated with increased risk of miscarriage and decreased probability of live birth.

The aims of the study were to describe temporal trends in the number, proportion, and per capita use of diabetes-related emergency department (ED) visits and to examine any racial/ethnic disparity in ED use for diabetes-related reasons. We analyzed the ED portion of the National Hospital Ambulatory Medical Care Survey from 1997 through 2007. Diabetes-related ED visits were identified by International Classification of Diseases, Ninth Revision codes. Descriptive statistics were developed. Weighted linear and logistic regression models were used to determine significance of temporal trends, and multivariate logistic regression was used to examine racial/ethnic disparities. A total of 20.2 million (1.69%; 95% confidence interval [CI], 1.59%-1.78%) ED visits were diabetes-related during the study period. We observed significant increases in the number and proportion of diabetes-related ED visits. Overall, there was a 5.6% relative annual increase in the proportion of ED visits that were diabetes-related during the study period. However, the per capita ED use among the population with diabetes did not change over time (P>.05 for trend). On multivariate analysis, black race (odds ratio, 1.8; 95% CI, 1.7-2.0), Hispanic ethnicity (odds ratio, 1.6; 95% CI, 1.4-1.8), and advancing age were associated with significantly higher odds of having a diabetes-related visit. Despite a marked increase in number and proportion of diabetes-related ED visits during the study period, the per capita use of ED services for diabetes-related visits among the diabetic population remained stable.

Many visitors, including military troops, who enter highland regions from low altitude areas may suffer from acute mountain sickness (AMS), which negatively impacts workable man-hours and increases healthcare costs. The aim of this study was to evaluate the population level risk factors and build a multivariate model, which might be applicable to reduce the effects of AMS on Chinese young men traveling to this region. Chinese highland military medical records were used to obtain data of young men (n = 3727) who entered the Tibet plateau between the years of 2006-2009. The relationship between AMS and travel profile, demographic characteristics, and health behaviors were evaluated by logistic regression. Univariate logistic models estimated the crude odds ratio. The variables that showed significance in the univariate model were included in a multivariate model to derive adjusted odds ratios and build the final model. Data corresponding to odd and even years (2 subsets) were analyzed separately and used in a simple cross-validation. Univariate analysis indicated that travel profile, prophylactic use, ethnicity, and province of birth were all associated with AMS in both subsets. In multivariate analysis, young men who traveled from lower altitude (600-800 m vs. 1300-1500 m, adjusted odds ratio (AOR) = 1.32-1.44) to higher altitudes (4100-4300 m vs. 2900-3100 m, AOR = 3.94-4.12; 3600-3700 m vs. 2900-3100 m, AOR = 2.71-2.74) by air or rapid land transport for emergency mission deployment (emergency land deployment vs. normal land deployment, AOR = 2.08-2.11; normal air deployment vs. normal land deployment, AOR = 2.00-2.20; emergency air deployment vs. normal land deployment, AOR = 2.40-3.34) during the cold season (cold vs. warm, AOR = 1.25-1.28) are at great risk for developing AMS. Non-Tibetan male soldiers (Tibetan vs. Han, AOR = 0.03-0.08), born and raised in lower provinces (eastern vs. northwestern, AOR = 1.32-1.39), and deployed without prophylaxis (prophylactic drug vs. none, AOR = 0.75-0.76), also represented a population at significantly increased risk for AMS. The predicted model was built; the area under receiver operating characteristic curve was 0.703. Before a group of young men first enter a high altitude area, it is important that a health service plan should be made referring to the group's travel profile and with respect to young men's ethnicity and province of birth. Low-cost Chinese traditional prophylactic drugs might have some effect on decreasing the risk of AMS, although this needs further verification.

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.

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.

Yellow tongue coating is one of the clinical signs for diabetes mellitus according to traditional East Asian medicine. Few reports have been available on the association between yellow tongue coating and the prevalence of type 2 diabetes in the general population. We examined that association among population samples of non-smoking men and women. The study subjects were Japanese non-smoking men (n = 315) and women (n = 654) aged 30-79 years who resided in Toon city and participated in the Toon Health Study from July 2011 through November 2014. Tongue coating was assessed by a nationally licensed acupuncturist and classified into three categories of white (normal), light yellow, and yellow. We performed an oral glucose tolerance test to confirm the presence of diabetes mellitus and prediabetes. The associations between yellow tongue coating and the prevalence of diabetes mellitus and prediabetes were examined using multivariable logistic regression analyses, adjusting for age, sex, body mass index, drinking status, and physical activity. The multivariable odds ratios of diabetes mellitus were 1.39 (95% confidence interval [CI], 0.72-2.67) for light yellow tongue coating and 2.23 (95% CI, 1.16-4.30) for yellow tongue coating compared with white tongue coating. The respective multivariable odds ratios of prediabetes were 1.13 (95% CI, 0.80-1.61) and 1.43 (95% CI, 0.96-2.12). Yellow tongue coating was associated with higher prevalence of diabetes mellitus and tended to be associated with that of prediabetes among Japanese non-smoking men and women.

Associations between sex hormones and sleep habits originate mainly from small and selected patient-based samples. We examined data from a population-based sample with various sleep characteristics and the major part of sex hormones measured by mass spectrometry. We used data from 204 men and 213 women of the cross-sectional Study of Health in Pomerania-TREND. Associations of total T (TT) and free T, androstenedione (ASD), estrone, estradiol (E2), dehydroepiandrosterone-sulphate, SHBG, and E2 to TT ratio with sleep measures (including total sleep time, sleep efficiency, wake after sleep onset, apnea-hypopnea index [AHI], Insomnia Severity Index, Epworth Sleepiness Scale, and Pittsburgh Sleep Quality Index) were assessed by sex-specific multivariable regression models. In men, age-adjusted associations of TT (odds ratio 0.62; 95% confidence interval (CI) 0.46-0.83), free T, and SHBG with AHI were rendered nonsignificant after multivariable adjustment. In multivariable analyses, ASD was associated with Epworth Sleepiness Scale (β-coefficient per SD increase in ASD: -0.71; 95% CI: -1.18 to -0.25). In women, multivariable analyses showed positive associations of dehydroepiandrosterone-sulphate with wake after sleep onset (β-coefficient: .16; 95% CI 0.03-0.28) and of E2 and E2 to TT ratio with Epworth Sleepiness Scale. Additionally, free T and SHBG were associated with AHI in multivariable models among premenopausal women. The present cross-sectional, population-based study observed sex-specific associations of androgens, E2, and SHBG with sleep apnea and daytime sleepiness. However, multivariable-adjusted analyses confirmed the impact of body composition and health-related lifestyle on the association between sex hormones and sleep.

Depressive symptoms and psychosocial stress at work among older employees in three continents

Background To assess whether an association of psychosocial stress at work with depressive symptoms among older employees is evident in a set of comparable empirical studies from Europe, North America and Asia. Methods Cross-sectional and longitudinal multivariate regression analyses of data from 4 cohort studies with elder workers (2004 and 2006) testing associations of psychosocial stress at work (‘effort-reward imbalance’; ‘low control’) with depressive symptoms. Results Cross-sectional analyses from 17 countries with 14.236 participants reveal elevated odds ratios of depressive symptoms among people experiencing high work stress compared to those with low or no work stress. Adjusted odds ratios vary from 1.64 (95% CI 1.02-2.63) in Japan to 1.97 (95% CI 1.75-2.23) in Europe and 2.28 (95% CI 1.59-3.28) in the USA. Odds ratios from additional longitudinal analyses (in 13 countries) controlling for baseline depression are smaller, but remain in part significant. Conclusion Findings indicate that psychosocial stress at work might be a relevant risk factor for depressive symptoms among older employees across countries and continents. This observation may call for global policy efforts to improve quality of work in view of a rapidly aging workforce, in particular in times of economic globalization. PMID:22818354

The aim of this study was to evaluate the factors associated with the development of atrial fibrillation (AF) in patients with rheumatic mitral stenosis (MS). A total of 146 consecutive patients with rheumatic MS were screened. They were accepted to be in AF group and sinus rhythm group according to their rhythm in the baseline ECG. After screening, 38 patients were excluded due to hyperthyroidism (n = 13), chronic obstructive pulmonary disease (n = 22), malignancy (n = 2) and rheumatoid arthritis (n = 1). Therefore, remaining 108 patients, 74 of whom in sinus rhythm (MS-SR) and 34 of whom in AF (MS-AF) constituted study population. Fourty age- and gender-matched patients constituted control group. Factors associated with development of AF in multivariable analysis included High sensitivity C reactive protein (P = 0.005; odds ratio, 3.44; 95% confidence interval, 1.44-8.22), N-terminal of brain natriuretic peptide precursor (P < 0.0001; odds ratio, 1.03; 95% confidence interval, 1.02-1.06) and left atrial diameter (P < 0.0001; odds ratio, 1.68; 95% confidence interval, 1.32-2.14). Present study suggests that High sensitivity C reactive protein, N-terminal of brain natriuretic peptide precursor and left atrial diameter are associated with development AF in patients with MS.

We identified factors associated with early and late postoperative seizure control in patients with supratentorial meningioma plus preoperative seizures. In this retrospective study, univariate analysis and multivariate logistic regression analysis compared 24 clinical variables according to the occurrence of early (≤1 week) or late (>1 week) postoperative seizures. Sixty-two of 97 patients (63.9 %) were seizure free for the entire postoperative follow-up period (29.5 ± 11.8 months), while 13 patients (13.4 %) still had frequent seizures at the end of follow-up. Fourteen of 97 patients (14.4 %) experienced early postoperative seizures, and emergence of new postoperative neurological deficits was the only significant risk factor (odds ratio = 7.377). Thirty-three patients (34.0 %) experienced late postoperative seizures at some time during follow-up, including 12 of 14 patients with early postoperative seizures. Associated risk factors for late postoperative seizures included tumor progression (odds ratio = 7.012) and new permanent postoperative neurological deficits (odds ratio = 4.327). Occurrence of postoperative seizures in patients with supratentorial meningioma and preoperative seizure was associated with new postoperative neurological deficits. Reduced cerebral or vascular injury during surgery may lead to fewer postoperative neurological deficits and better seizure outcome.

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.

This study estimated the prevalence of self-rated visual impairment among US adults with diabetes and identified correlates of such impairment. Self-reported data from the 1995 Behavioral Risk Factor Surveillance System survey of adults 18 years and older with diabetes were analyzed. Correlates of visual impairment were examined by multiple logistic regression analysis. The prevalence of self-rated visual impairment was 24.8% (95% confidence interval [CI] = 22.3%, 27.3%). Among insulin users, multivariable-adjusted odds ratios were 4.9 (95% CI = 2.6, 9.2) for those who had not completed high school and 1.8 (95% CI = 1.0, 2.8) for those who had completed high school compared with those with higher levels of education. Comparable estimates of odds ratios for nonusers of insulin were 2.2 (95% CI = 1.4, 3.4) and 1.3 (95% CI = 0.9, 2.0), respectively. Among nonusers, the adjusted odds for minority adults were 2.4 (95% CI = 1.0, 3.7) times the odds for non-Hispanic Whites. By these data, 1.6 million US adults with diabetes reported having some degree of visual impairment. Future research on the specific causes of visual impairment may help in estimating the avoidable public health burden.

To examine possible associations between perceived neighborhood environments and obesity among a U.S. nationally representative sample of Afro-Caribbean, African American, and Non-Hispanic white adults. Data was used from the 2001-2003 National Survey of American Life (NSAL). All measures including neighborhood characteristics, height, and weight were self-reported. Multivariate logistic regression was used to compute odds ratios (ORs) of obesity (body mass index (BMI) ≥ 30 kg/m(2)) based on perceived neighborhood physical and social characteristics. The odds of obesity were significantly lower for adults who reported involvement in clubs, associations, or help groups (odds ratio (OR): 0.62; 95% confidence interval (CI): 0.44, 0.85) and perceived that they had a park, playground, or open space in their neighborhood (odds ratio (OR): 0.68; 95% confidence interval (CI): 0.47, 0.98). These associations remained significant after adjusting for leisure-time physical activity. Race/ethnicity appeared to modify the association between involvement in clubs, associations, or help groups and obesity. Providing parks, playgrounds, or open space or increasing the perception of those amenities may assist in the prevention of obesity, especially in ethnically diverse neighborhoods in the United States. More research is needed to investigate how perceptions of the neighborhood environment influence obesity and whether perceptions of the neighborhood environment differ between individuals within the same neighborhoods.

This study describes the prevalence and correlates of past-year intimate partner violence (IPV) among displaced women. We used bivariate and multivariate analyses to assess the relationships between IPV and select variables of interest. Multivariate logistic regression modeling revealed that women who had experienced outsider violence were 11 times as likely (adjusted odds ratio [AOR] = 11.21; confidence interval, CI [5.25, 23.96]) to have reported IPV than women who had not experienced outsider violence. IPV in conflict-affected settings is a major public health concern that requires effective interventions; our results suggest that women who had experienced outsider violence are at greater risk of IPV. © The Author(s) 2015.

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.

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.

To identify factors affecting the sex ratio at birth. Cross-sectional study. Obstetric department of a public hospital in Hong Kong. All pregnant women delivered between 2001 and 2010. Sex ratio at birth versus women's eligibility status, age, parity, number of miscarriages or terminations of pregnancy, and number of fetuses were analysed using the Chi squared test. Multivariate regression was used to determine the effects of multiple factors on the sex of the newborn. A total of 54 039 cases were reviewed. The sex ratio at birth changed since 2003, and became unbalanced (>107 males per 100 females) since 2006 revealed by a significant increase in males per 100 females, from 106.6 in 2001-2005 to 111.4 in 2006-2010. From 2001 to 2010, the sex ratio at birth increased from being balanced to becoming unbalanced in eligible persons, and became more unbalanced in non-eligible persons. The ratio increased in eligible persons after having two children, but in non-eligible persons after having one child. The sex ratio at birth was unbalanced (1.095) in singleton pregnancies, but balanced (1.019) in multiple pregnancies. Based on logistic regression, the chance of a male baby being born increased with parity of 2 or above (odds ratio=1.1; P<0.001), non-eligible person status (odds ratio=1.05; P=0.034), and delivery in the period 2006-2010 (odds ratio=1.04; P=0.019). The ratio was not increased with advanced maternal age, the number of miscarriages/terminations of pregnancy, and number of fetuses. Compared with 2001-2005, the sex ratio at birth became unbalanced in 2006-2010. An unbalanced ratio ensued in the latter period in both eligible and non-eligible persons, but to a greater extent and even after having one child in the latter group.

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.

Studies on blood product transfusions after trauma recommend targeting specific ratios to reduce mortality. Although crystalloid volumes as little as 1.5 L predict increased mortality after trauma, little data is available regarding the threshold of red blood cell (RBC) transfusion volume that predicts increased mortality. Data from a level I trauma center between January 2000 and December 2008 were reviewed. Trauma patients who received at least 100 mL RBC in the emergency department (ED) were included. Each unit of RBC was defined as 300 mL. Demographics, RBC transfusion volume, and mortality were analyzed in the nonelderly (<70 y) and elderly (≥70 y). Multivariate logistic regression was performed at various volume cutoffs to determine whether there was a threshold transfusion volume that independently predicted mortality. A total of 560 patients received ≥100 mL RBC in the ED. Overall mortality was 24.3%, with 22.5% (104 deaths) in the nonelderly and 32.7% (32 deaths) in the elderly. Multivariate logistic regression demonstrated that RBC transfusion of ≥900 mL was associated with increased mortality in both the nonelderly (adjusted odds ratio 2.06, P = 0.008) and elderly (adjusted odds ratio 5.08, P = 0.006). Although transfusion of greater than 2 units in the ED was an independent predictor of mortality, transfusion of 2 units or less was not. Interestingly, unlike crystalloid volume, stepwise increases in blood volume were not associated with stepwise increases in mortality. The underlying etiology for mortality discrepancies, such as transfusion ratios, hypothermia, or immunosuppression, needs to be better delineated. Copyright © 2013 Elsevier Inc. All rights reserved.

BACKGROUND Donor to recipient lung size matching at lung transplantation (LTx) can be estimated by the predicted total lung capacity (pTLC)ratio (donor pTLC/recipient pTLC). We aimed to determine whether the pTLC-ratio is associated with the risk of primary graft dysfunction (PGD) after bilateral LTx (BLT). METHODS We calculated the pTLC-ratio for 812 adult BLTs from the Lung Transplant Outcomes Group between 3/2002-12/2010. Patients were stratified by pTLC-ratio>1.0 (“oversized”) and pTLC-ratio≤1.0 (“undersized”). PGD was defined as any ISHLT grade 3 PGD within 72 hours of reperfusion (PGD 3). We analyzed the association between risk factors and PGD using multivariable conditional logistic regression. As transplant diagnoses can influence the size matching decisions and also modulate the risk for PGD, we performed pre-specified analyses by assessing the impact of lung size mismatch within diagnostic categories. RESULTS In univariate analyses oversizing was associated with a 39% lower odds of PGD3 (OR 0.61, 95% CI, p=0.003). In a multivariate model accounting for center effects and known PGD risks, oversizing remained independently associated with a decreased odds of PGD3 (OR 0.58, 95% CI 0.38-0.88, p=0.01). The risk adjusted point estimate was similar for the non-COPD diagnoses groups (OR 0.52, 95%CI 0.32-0.86, p=0.01); however there was no detected association within the COPD group (OR 0.72, 95% CI 0.29-1.78, p=0.5). CONCLUSION Oversized allografts are associated with a decreased risk of PGD3 after BLT; this effect appears most apparent in non-COPD patients. PMID:25447586

The management of upper gastrointestinal bleeding (UGIB) in anticoagulated patients with supratherapeutic international normalized ratios (INRs) presents a challenge. The purpose of the study was to evaluate the safety of endoscopic therapy for UGIB in anticoagulated patients with supratherapeutic INR in terms of rebleeding and therapeutic outcomes. One hundred ninety-two anticoagulated patients who underwent endoscopic treatment for UGIB were enrolled in the study. Patients were divided into 2 groups based on the occurrence of rebleeding within 30 days of the initial therapeutic endoscopy: no-rebleeding group (n = 168) and rebleeding group (n = 24). The overall rebleeding rate was 12.5%. Bleeding from gastric cancer and bleeding at the duodenum were significantly related to rebleeding in a univariate analysis. Multivariate analysis determined that presenting symptoms other than melena (hematemesis, hematochezia, or others) (odds ratio, 3.93; 95% confidence interval, 1.44-10.76) and bleeding from gastric cancer (odds ratio, 6.10; 95% confidence interval, 1.27-29.25) were significant factors predictive of rebleeding. Supratherapeutic INR at the time of endoscopic therapy was not significantly associated with rebleeding in either univariate or multivariate analysis. Significant differences in bleeding-related mortality, additional intervention to control bleeding, length of hospital stay, and transfusion requirements were revealed between the rebleeding and no-rebleeding groups. There were no significant differences in therapeutic outcomes between patients with INR within the therapeutic range and those with supratherapeutic INR. Supratherapeutic INR at the time of endoscopic therapy did not change rebleeding and therapeutic outcomes. Thus, we should consider endoscopic therapy for UGIB in anticoagulated patients, irrespective of INR at the time of endoscopic therapy.

Care coordination has been identified as a key strategy in improving the effectiveness, safety, and efficiency of the US health care system. Our objective was to determine whether population or health care system issues are associated with primary care coordination gaps in the United States and other high-income countries. We analyzed data from the 2013 Commonwealth Fund International Health Policy (IHP) survey with multivariate logistic regression analysis. Respondents were adult primary care patients from 11 countries: Australia, Canada, France, Germany, the Netherlands, New Zealand, Norway, Sweden, Switzerland, United Kingdom, and the United States. Poor primary care coordination was defined as participants reporting at least 3 gaps in the coordination of care out of a maximum of 5. Analyses were based on 13,958 respondents. The rate of poor primary care coordination was 5.2% (724/13,958 respondents) overall and highest in the United States, at 9.8% (137/1,395 respondents). Multivariate regression analysis among all respondents found that they were less likely to experience poor primary care coordination if their primary care physician often or always knew their medical history, spent sufficient time, involved them, and explained things well (odds ratio = 0.6 for each). Poor primary care coordination was more likely to occur among patients with chronic conditions (odds ratios = 1.4-2.1 depending on number) and patients younger than 65 years (odds ratios = 1.6-2.3 depending on age-group). Among US respondents, insurance status, health status, household income, and sex were not associated with poor primary care coordination. The United States had the highest rate of poor primary care coordination among the 11 high-income countries evaluated. An established relationship with a primary care physician was significantly associated with better care coordination, whereas being chronically ill or younger was associated with poorer care coordination. © 2017 Annals of Family Medicine, Inc.

In primary intracerebral hemorrhage, the presence of contrast extravasation after computed tomographic angiography (CTA), termed the spot sign, predicts hematoma expansion and mortality. Because the biological underpinnings of the spot sign are not fully understood, we investigated whether the rate of contrast extravasation, which may reflect the rate of bleeding, predicts expansion and mortality beyond the simple presence of the spot sign. Consecutive intracerebral hemorrhage patients with first-pass CTA followed by a 90-second delayed postcontrast CT (delayed CTA) were included. CTAs were reviewed for spot sign presence by 2 blinded readers. Spot sign volumes on first-pass and delayed CTA and intracerebral hemorrhage volumes were measured using semiautomated software. Extravasation rates were calculated and tested for association with hematoma expansion and mortality using uni- and multivariable logistic regressions. One hundred and sixty-two patients were included, 48 (30%) of whom had ≥1 spot sign. Median spot sign volume was 0.04 mL on first-pass CTA and 0.4 mL on delayed CTA. Median extravasation rate was 0.23 mL/min overall and 0.30 mL/min among expanders versus 0.07 mL/min in nonexpanders. Extravasation rates were also significantly higher in patients who died in hospital: 0.27 mL/min versus 0.04 mL/min. In multivariable analysis, the extravasation rate was independently associated with in-hospital mortality (odds ratio, 1.09 [95% confidence interval, 1.04-1.18], P=0.004), 90-day mortality (odds ratio, 1.15 [95% confidence interval, 1.08-1.27]; P=0.0004), and hematoma expansion (odds ratio, 1.03 [95% confidence interval, 1.01-1.08]; P=0.047). Contrast extravasation rate, or spot sign growth, further refines the ability to predict hematoma expansion and mortality. Our results support the hypothesis that the spot sign directly measures active bleeding in acute intracerebral hemorrhage. © 2015 American Heart Association, Inc.

Age is an important risk factor for morbidity after lung resection. This study was performed to identify specific risk factors for complications after lung resection in octogenarians. A prospective database containing patients aged 80 years or older, who underwent lung resection at a single institution between January 2000 and June 2009, was reviewed. Preoperative, histopathologic, perioperative, and outcome variables were assessed. Morbidity was measured as a patient having any perioperative event as defined by the Society of Thoracic Surgeons General Thoracic Surgery Database. A multivariable risk model for morbidity was developed using a panel of established preoperative and operative variables. Survival was calculated using the Kaplan-Meier method. During the study period, 193 patients aged 80 years or older (median age 82 years) underwent lung resection: wedge resection in 77, segmentectomy in 13, lobectomy in 96, bilobectomy in four, and pneumonectomy in three. Resection was accomplished via thoracoscopy in 149 patients (77%). Operative mortality was 3.6% (seven patients) and morbidity was 46% (89 patients). A total of 181 (94%) patients were discharged directly home. Postoperative events included atrial arrhythmia in 38 patients (20%), prolonged air leak in 24 patients (12%), postoperative transfusion in 22 patients (11%), delirium in 16 patients (8%), need for bronchoscopy in 14 patients (7%), and pneumonia in 10 patients (5%). Significant predictors of morbidity by multivariable analysis included resection greater than wedge (odds ratio 2.98, p=0.006), thoracotomy as operative approach (odds ratio 2.6, p=0.03), and % predicted forced expiratory volume in 1s (odds ratio 1.28 for each 10% decrement, p=0.01). Octogenarians can undergo lung resection with low mortality. Extent of resection, use of a thoracotomy, and impaired lung function increase the risk of complications. Careful evaluation is necessary to select the most appropriate approach in octogenarians being considered for lung resection. Copyright © 2010 European Association for Cardio-Thoracic Surgery.

Extreme body mass index (BMI; either very high or very low) has been associated with increased risk of adverse perioperative outcome in adults undergoing cardiac surgery. The effect of BMI on perioperative outcomes in congenital heart disease patients has not been evaluated. A multicenter retrospective cohort study was performed studying patients 10 to 35 years of age undergoing a congenital heart disease operation in the Society of Thoracic Surgeons Congenital Heart Surgery Database between January 1, 2010, and December 31, 2015. The primary outcomes were operative mortality and a composite outcome (1 or more of operative mortality, major adverse event, prolonged hospital length of stay, and wound infection/dehiscence). The associations between age- and sex-adjusted BMI percentiles and these outcomes were assessed, with adjustment for patient-level risk factors, with multivariate logistic regression. Of 18 337 patients (118 centers), 16% were obese, 15% were overweight, 53% were normal weight, 7% were underweight, and 9% were severely underweight. Observed risks of operative mortality ( P =0.04) and composite outcome ( P <0.0001) were higher in severely underweight and obese subjects. Severely underweight BMI was associated with increased unplanned cardiac operation and reoperation for bleeding. Obesity was associated with increased risk of wound infection. In multivariable analysis, the association between BMI and operative mortality was no longer significant. Obese (odds ratio, 1.28; P =0.008), severely underweight (odds ratio, 1.29; P <0.0001), and underweight (odds ratio, 1.39; P =0.002) subjects were associated with increased risk of composite outcome. Obesity and underweight BMI were associated with increased risk of composite adverse outcome independently of other risk factors. Further research is necessary to determine whether BMI represents a modifiable risk factor for perioperative outcome. © 2017 American Heart Association, Inc.

Relationship between obesity, ethnicity and risk of late stillbirth: a case control study

PubMed Central

2011-01-01

Background In high income countries there has been little improvement in stillbirth rates over the past two decades. Previous studies have indicated an ethnic disparity in the rate of stillbirths. This study aimed to determine whether maternal ethnicity is independently associated with late stillbirth in New Zealand. Methods Cases were women with a singleton, late stillbirth (≥28 weeks' gestation) without congenital abnormality, born between July 2006 and June 2009 in Auckland, New Zealand. Two controls with ongoing pregnancies were randomly selected at the same gestation at which the stillbirth occurred. Women were interviewed in the first few weeks following stillbirth, or at the equivalent gestation for controls. Detailed demographic data were recorded. The study was powered to detect an odds ratio of 2, with a power of 80% at the 5% level of significance, given a prevalence of the risk factor of 20%. A multivariable regression model was developed which adjusted for known risk factors for stillbirth, as well as significant risk factors identified in the current study, and adjusted odds ratios and 95% confidence intervals were calculated. Results 155/215 (72%) cases and 310/429 (72%) controls consented. Pacific ethnicity, overweight and obesity, grandmultiparity, not being married, not being in paid work, social deprivation, exposure to tobacco smoke and use of recreational drugs were associated with an increased risk of late stillbirth in univariable analysis. Maternal overweight and obesity, nulliparity, grandmultiparity, not being married and not being in paid work were independently associated with late stillbirth in multivariable analysis, whereas Pacific ethnicity was no longer significant (adjusted Odds Ratio 0.99; 0.51-1.91). Conclusions Pacific ethnicity was not found to be an independent risk factor for late stillbirth in this New Zealand study. The disparity in stillbirth rates between Pacific and European women can be attributed to confounding factors such as maternal obesity and high parity. PMID:21226915

Delayed presentation to hospital after an acute stroke is a major explanation given for low thrombolysis rates. This study aimed to investigate the factors associated with delays in presentation after an acute stroke and changes after a mass media campaign. Data were from a population-based study involving 1392 patients with first-ever strokes between 2002 and 2010 in a multiethnic South London population. Associations were determined between prehospital delay (≥3 hours) and variables of interest, including ethnicity, by using multivariate logistic regression analyses. Differences in prehospital delay and thrombolysis rates were determined for the period immediately before and after the FAST mass media campaign (2007/2008 versus 2009/2010). The median (Q(1) to Q(3)) time to presentation was 4.73 (1.55 to 12.70) hours, and 550 (39.5%) presented within 3 hours of symptom onset. In multivariate analysis, patients of black ethnicity had increased odds of delay (odds ratio: 1.63; 95% confidence interval, 1.11 to 2.38), whereas those with more severe strokes characterized by a higher National Institutes of Health Stroke Scale score (odds ratio: 0.35; 95% confidence interval, 0.20 to 0.61) had reduced odds of delay. There was no difference in the proportion of patients who arrived within 3 hours (P=0.30) in the period immediately before and after the FAST campaign (40.7% in 2007/2008 versus 44.9% in 2009/2010). Among patients with ischemic stroke, 119 (11.0%) received thrombolysis between 2002 and 2010, with no difference observed between the pre- and postcampaign periods (16.9% versus 16.4%). Significant delays in seeking care after stroke still occur in this population despite efforts to increase public awareness. Future educational programs must identify and specifically address factors that influence behavior and should target those at higher risk of delay.

Rationale: Links between occupational exposures and morbidity in individuals with established chronic obstructive pulmonary disease (COPD) remain unclear. Objectives: To determine the impact of occupational exposures on COPD morbidity. Methods: A job exposure matrix (JEM) determined occupational exposure likelihood based on longest job in current/former smokers (n = 1,075) recruited as part of the Subpopulations and Intermediate Outcomes in COPD Study, of whom 721 had established COPD. Bivariate and multivariate linear regression models estimated the association of occupational exposure with COPD, and among those with established disease, the occupational exposure associations with 6-minute-walk distance (6MWD), the Modified Medical Research Council Dyspnea Scale (mMRC), the COPD Assessment Test (CAT), St. George’s Respiratory Questionnaire (SGRQ), 12-item Short-Form Physical Component (SF-12), and COPD exacerbations requiring health care utilization, adjusting for demographics, current smoking status, and cumulative pack-years. Measurements and Main Results: An intermediate/high risk of occupational exposure by JEM was found in 38% of participants. In multivariate analysis, those with job exposures had higher odds of COPD (odds ratio, 1.44; 95% confidence interval, 1.04–1.97). Among those with COPD, job exposures were associated with shorter 6MWDs (−26.0 m; P = 0.006); worse scores for mMRC (0.23; P = 0.004), CAT (1.8; P = 0.003), SGRQ (4.5; P = 0.003), and SF-12 Physical (−3.3; P < 0.0001); and greater odds of exacerbation requiring health care utilization (odds ratio, 1.55; P = 0.03). Conclusions: Accounting for smoking, occupational exposure was associated with COPD risk and, for those with established disease, shorter walk distance, greater breathlessness, worse quality of life, and increased exacerbation risk. Clinicians should obtain occupational histories from patients with COPD because work-related exposures may influence disease burden. PMID:25562375

To analyze the characteristics, associations, and outcomes of prevalence of the right heart and to evaluate the use of sonography to predict the risk of a poor prognosis in fetuses with this condition. We conducted a retrospective cohort study of 182 fetuses with prevalence of the right heart. At the initial evaluation, the left ventricle (LV) and right ventricle (RV) sizes, left atrium and right atrium sizes, great artery diameters, appearance of the aortic arch and ductus arteriosus arch, and flow direction across the foramen ovale and aortic arch were documented. Malformations were documented in fetuses with intracardiac anomalies, who were divided into groups with and without coexisting extracardiac defects. The RV-LV diameter ratio and main pulmonary artery-to-aortic root diameter ratio were calculated and compared. The following variables were analyzed: coexisting intracardiac anomalies, associated extracardiac anomalies, diagnosis before 24 gestational weeks, fetal growth restriction, reversed flow across the foramen ovale, reversed flow in the aortic arch, and RV-LV ratio greater than 2.0. Relationships between these sonographic findings and the prognosis were evaluated by multivariable logistic regression. Of the 182 fetuses, 1 (0.5%) had intrauterine death, and 25 (13.7%) had neonatal death; 1 (0.5%) had selective reduction, and 106 (58.2%) underwent termination of pregnancy; 49 (26.9%) survived at this writing. The mean RV-LV ratio was 1.67. Multivariable logistic regression revealed that only 2 sonographic parameters, coexisting intracardiac anomalies (odds ratio, 17.75; 95% confidence interval, 4.18-75.26) and diagnosis before 24 weeks (odds ratio, 17.26; 95% confidence interval, 1.80-165.39) were significantly associated with a poor prognosis. The sonographic parameters of coexisting intracardiac anomalies and diagnosis before 24 gestational weeks are significant independent predictors of a poor prognosis in fetuses with prevalence of the right heart. Combinations of these risk factors may be useful in prenatal consultation. © 2014 by the American Institute of Ultrasound in Medicine.

Japanese diets contain a relatively high amount of carbohydrates, and its high dietary glycemic index and glycemic load may raise the risk of diabetes in the Japanese population. The current study evaluated the associations between the dietary glycemic index, glycemic load, and the risk of type 2 diabetes in a population based cohort in Japan. We observed 27,769 men and 36,864 women (45-75 y) who participated in the second survey of the Japan Public Health Center-based Prospective Study. The dietary glycemic index and glycemic load were estimated using a food-frequency questionnaire. The development of diabetes was reported in a questionnaire administered five years later, and the associations were analyzed using logistic regression after controlling for age, area, total energy intake, smoking status, family history of diabetes, physical activity, hypertension, BMI, alcohol intake, magnesium, calcium, dietary fiber and coffee intake, and occupation. The dietary glycemic load was positively associated with the risk of diabetes among women: the multivariable-adjusted odds ratio comparing the highest vs. the lowest quartile was 1.52 (95% CI, 1.13-2.04; P-trend = 0.01). The association was implied to be stronger among women with BMI < 25 than the women with BMI ≥ 25. The dietary glycemic index was positively associated with the risk of diabetes among men with a high intake of total fat: the multivariable-adjusted odds ratio comparing the highest vs. the lowest quartile was 1.46 (95% CI, 0.94-2.28; P-trend = 0.04). Among women with a high total fat intake, those in the first and second quartiles of the dietary glycemic index had a significant reduced risk of diabetes, compared with those in the first quartile who had a lower total fat level (multivariable-adjusted odds ratio = 0.59 with 95% CI, 0.37-0.94, and odds ratio = 0.63 with 95% CI, 0.40-0.998 respectively). The population-based cohort study in Japan indicated that diets with a high dietary glycemic load increase the risk of type 2 diabetes among women. Total fat intake may modify the association between the dietary glycemic index and the risk of type 2 diabetes among men and women.

Background and Purpose— Statin therapy is associated with a lower risk of ischemic stroke supporting a causal role of low-density lipoprotein (LDL) cholesterol. However, more evidence is needed to answer the question whether LDL cholesterol plays a causal role in ischemic stroke subtypes. In addition, it is unknown whether high-density lipoprotein cholesterol and triglycerides have a causal relationship to ischemic stroke and its subtypes. Our aim was to investigate the causal role of LDL cholesterol, high-density lipoprotein cholesterol, and triglycerides in ischemic stroke and its subtypes through Mendelian randomization (MR). Methods— Summary data on 185 genome-wide lipids-associated single nucleotide polymorphisms were obtained from the Global Lipids Genetics Consortium and the Stroke Genetics Network for their association with ischemic stroke (n=16 851 cases and 32 473 controls) and its subtypes, including large artery atherosclerosis (n=2410), small artery occlusion (n=3186), and cardioembolic (n=3427) stroke. Inverse-variance–weighted MR was used to obtain the causal estimates. Inverse-variance–weighted multivariable MR, MR-Egger, and sensitivity exclusion of pleiotropic single nucleotide polymorphisms after Steiger filtering and MR-Pleiotropy Residual Sum and Outlier test were used to adjust for pleiotropic bias. Results— A 1-SD genetically elevated LDL cholesterol was associated with an increased risk of ischemic stroke (odds ratio: 1.12; 95% confidence interval: 1.04–1.20) and large artery atherosclerosis stroke (odds ratio: 1.28; 95% confidence interval: 1.10–1.49) but not with small artery occlusion or cardioembolic stroke in multivariable MR. A 1-SD genetically elevated high-density lipoprotein cholesterol was associated with a decreased risk of small artery occlusion stroke (odds ratio: 0.79; 95% confidence interval: 0.67–0.90) in multivariable MR. MR-Egger indicated no pleiotropic bias, and results did not markedly change after sensitivity exclusion of pleiotropic single nucleotide polymorphisms. Genetically elevated triglycerides did not associate with ischemic stroke or its subtypes. Conclusions— LDL cholesterol lowering is likely to prevent large artery atherosclerosis but may not prevent small artery occlusion nor cardioembolic strokes. High-density lipoprotein cholesterol elevation may lead to benefits in small artery disease prevention. Finally, triglyceride lowering may not yield benefits in ischemic stroke and its subtypes.

Objective To investigate whether episiotomy, perineal laceration, and operative delivery are associated with pelvic floor disorders after vaginal childbirth. Methods This is a planned analysis of data for a cohort study of pelvic floor disorders. Participants who had experienced at least one vaginal birth were recruited 5–10 years after delivery of their first child. Obstetric exposures were classified by review of hospital records. At enrollment, pelvic floor outcomes, including stress incontinence, overactive bladder, anal incontinence, and prolapse symptoms were assessed with a validated questionnaire. Pelvic organ support was assessed using the Pelvic Organ Prolapse Quantification system. Logistic regression analysis was used to estimate the relative odds of each pelvic floor disorder by obstetric history, adjusting for relevant confounders. Results Of 449 participants, 71 (16%) had stress incontinence, 45 (10%) had overactive bladder, 56 (12%) had anal incontinence, 19 (4%) had prolapse symptoms and 64 (14%) had prolapse to or beyond the hymen on examination. Forceps delivery increased the odds of each pelvic floor disorder considered, especially overactive bladder (odds ratio 2.92, 95% confidence interval 1.44, 5.93) and prolapse (odds ratio 1.95, 95% confidence interval 1.03, 3.70). Episiotomy was not associated with any of these pelvic floor disorders. In contrast, women with a history of more than one spontaneous perineal laceration were significantly more likely to have prolapse to or beyond the hymen (odds ratio 2.34, 95% confidence interval 1.13, 4.86). Our multivariable results suggest that one additional woman would develop prolapse for every 8 women who experienced at least one forceps birth (versus delivering all her children by spontaneous vaginal birth). Conclusion Forceps deliveries and perineal lacerations, but not episiotomies, were associated with pelvic floor disorders 5–10 years after a first delivery. PMID:22227639

Sleep-related complaints are common in adolescents, but their impact on the rate of motor vehicle crashes accidents is poorly known. We studied subjective sleep quality, driving habits, and self-reported car crashes in high-school adolescents. Self-administered questionnaires (with items exploring driving habits) were distributed to 339 students who had a driver's license and attended 1 of 7 high schools in Bologna, Italy. Statistical analysis were performed to describe lifestyle habits, sleep quality, sleepiness, and their relationship with the binary dependent variable (presence or absence of car crashes) to identify the factors significantly affecting the probability of car crashes in a multivariate binary logistic regression model. Nineteen percent of the sample reported bad sleep, 64% complained of daytime sleepiness, and 40% reported sleepiness while driving. Eighty students (24%), 76% of which were males, reported that they had already crashed at least once, and 15% considered sleepiness to have been the main cause of their crash. As compared with adolescents who had not had a crash, those who had at least 1 previous crash reported that they more frequently used to drive (79% vs 62%), drove at night (25% vs 9%), drove while sleepy (56% vs 35%), had bad sleep (29% vs 16%), and used stimulants such as caffeinated soft drinks (32% vs 19%), tobacco (54% vs 27%), and drugs (21% vs 7%). The logistic procedure established a significant predictive role of male sex (p < 0.0001; odds ratio = 3.3), tobacco use (p < 0.0001; odds ratio = 3.2), sleepiness while driving (p = 0.010; odds ratio = 2.1), and bad sleep (p = 0.047; odds ratio = 1.9) for the crash risk. Our results confirm the high prevalence of sleep-related complaints among adolescents and highlight their independent role on self-reported crash risk.

Adverse effect of excessive work on health has been suggested previously, but it was not documented in cerebrovascular diseases. The authors investigated whether excessive working conditions would associate with increased risk of haemorrhagic stroke. A nationwide matched case-control study database, which contains 940 cases of incident haemorrhagic stroke (498 intracerebral haemorrhages and 442 sub-arachnoid haemorrhages) with 1880 gender- and age- (± 5-year) matched controls, was analysed. Work-related information based on the regular job situation, including type of occupation, regular working time, duration of strenuous activity during regular work and shift work, was gathered through face-to-face interviews. Conditional logistic regression analyses were used for the multivariable analyses. Compared with white-collar workers, blue-collar workers had a higher risk for haemorrhagic stroke (odds ratio, 1.33 [95% confidence interval, 1.06-1.66]). Longer regular working time was associated with increased risk of haemorrhagic stroke [odds ratio, 1.38 (95% confidence interval, 1.05-1.81) for 8-12 h/day; odds ratio, 1.95 (95% confidence interval, 1.33-2.86) for ≥ 13 h/day; compared with ≤ 4 h/day]. Exposure to ≥ 8 h/week of strenuous activity also associated haemorrhagic stroke risk [odds ratio, 1.61 (95% confidence interval, 1.26-2.05); compared with no strenuous activity]. Shift work was not associated with haemorrhagic stroke (P = 0.98). Positive associations between working condition indices and haemorrhagic stroke risk were consistent regardless of haemorrhagic stroke sub-types and current employment status. Blue-collar occupation, longer regular working time and extended duration of strenuous activity during work may relate to an increased risk of haemorrhagic stroke. © 2012 The Authors.

Rubella causes disease in the fetus. Immunity to rubella is therefore, routinely screened in pregnant women. In this retrospective observational study, we assessed the levels of potential susceptibility to rubella in the population of a north London antenatal clinic. Risk factors for potential susceptibility to rubella and changes in potential susceptibility to rubella over time were studied. Almost all women were screened for potential susceptibility to rubella (99.8%). The majority were predicted to be immune (96.8%). Women booking in later years within the study period showed higher levels of potential susceptibility to rubella. Booking during each subsequent year in the study gave women an odds ratio of 0.91 (CI:0.84, 0.98, P = 0.009) of being predicted to have immunity against rubella. Age was associated with predicted immunity to rubella, with a 5.1% (CI:3.3%, 6.9%, P < 0.001) increased likelihood for every year older. Previous pregnancy was predictive of immunity against rubella with an odds ratio of 1.41 (CI 1.21, 1.61, P = 0.001). Those from a non-white ethnicity were less likely to have antibodies predictive of immunity (OR: 0.730, CI: 0.581, 0.879 P < 0.001). Country of birth was associated with differences in potential susceptibility, with those being born outside of the British Isles having an odds ratio for predicted immunity of 0.63 (CI:0.35,0.91, P = 0.001). Being born in a high-risk country for rubella non-immunity was also a risk factor, giving an odds ratio of predicted immunity to rubella of 0.55 (CI:0.32, 0.77, P < 0.001). © 2017 Wiley Periodicals, Inc.

We hypothesized that subclinical markers of vascular structure and function, which are independent predictors of cardiovascular disease, would be less frequent in subjects with ideal than poor cardiovascular health (CVH) as defined by the American Heart Association (AHA). Carotid parameters were measured using high-precision echotracking device in 9155 nonreferred participants attending a health checkup in a large health center in Paris (France) between 2008 and 2012. According to the AHA, participants with 0 to 2, 3 to 4, and 5 to 7 metrics (smoking, physical activity, body mass index, diet, blood glucose and total cholesterol, blood pressure) at the ideal level were categorized as having poor, intermediate, and ideal CVH. Carotid parameters were dichotomized according to their median value, and multivariable logistic regression analysis was performed. Mean age was 59.5 (SD 6.3) years; 39% were females, and ideal CVH was present in 10.11% of the study participants. After adjustment for age, sex, education, and living alone and compared with a poor CVH, an ideal CVH was associated with lower common carotid artery intima-media thickness (odds ratio=1.64; 95% confidence interval 1.40, 1.93), absence of carotid plaques (odds ratio=2.14; 95% confidence interval 1.60, 2.87), lower Young's elastic modulus (odds ratio=2.43; 95% confidence interval 2.07, 2.84), and higher carotid distensibility coefficient (odds ratio=2.90; 95% confidence interval 2.47, 3.41). In community subjects aged 50 to 75 years, ideal CVH was associated with substantially less arterial stiffness and thickness. These associations might contribute to the lower risk of cardiovascular diseases in subjects with ideal CVH. © 2016 American Heart Association, Inc.

The aim of this study was to investigate radiographically the prevalence of apical periodontitis (AP) and endodontic treatment in a sample of adult type II diabetic patients and control subjects. In a cross-sectional study, the radiographic records of 50 adult patients reporting a history of well-controlled type 2 diabetes mellitus (DM) (study group) and 50 age- and sex-matched subjects who reported no history of DM (control group) were examined. Periapical status of all teeth was assessed using the periapical index score. The average number of teeth per patient in the diabetic and control groups was 21.9 and 24.6 teeth, respectively (P = .012). AP in one or more teeth was found in 37 diabetic patients (74%) and in 21 control subjects (42%) (odds ratio = 3.9, P = .002). One or more root-filled teeth were found in 35 (70%) and 25 (50%) of diabetic and control subjects, respectively (odds ratio = 2.3, P = .043). Among diabetic patients with root-filled teeth, 16 (46%) had AP affecting at least one treated tooth. Among controls with root-filled teeth, 6 (24%) had AP affecting at least one treated tooth (P > .05). Adjusting for teeth number, multivariate logistic regression analysis showed that periapical status (odds ratio = 3.3, P = .0071) and the number of root-filled teeth (odds ratio = 1.7; P = .0035) were significantly associated with diabetic status. The results showed that in adult patients, type 2 DM is significantly associated with an increased prevalence of AP and endodontic treatment. Copyright © 2011 American Association of Endodontists.

To determine how age may modulate the association of a history of cancer with a 12-month history of anxiety and depressive disorders. The authors used population-based, cross-sectional surveys, the Collaborative Psychiatric Epidemiology Surveys. These surveys were conducted in the United States in 2001-2003 and included 16,423 adult participants, of whom 702 reported a cancer history. The Composite International Diagnostic Interview evaluated the presence of a 12-month history of anxiety and depressive disorders. Among those with a cancer history, older adults (≥60 years old) were less likely than younger adults (18-59 years old) to have a 12-month history of an anxiety or depressive disorder. Compared with their peers without cancer, younger adults with a cancer history had more anxiety (23.8% versus 13.9%) and depressive (16.0% versus 9.5%) disorders, whereas older adults with a cancer history had lower levels of anxiety (3.7% versus 6.3%) and depressive (1.9% versus 3.9%) disorders. In multivariable modeling, there was a statistically significant interaction between age group and cancer history, with the risk for anxiety and depressive disorders elevated in the younger age group with a cancer history (odds ratio: 5.84 and odds ratio: 6.13, respectively) but decreased in the older age group with a cancer history (odds ratio: 0.55 and odds ratio: 0.45, respectively). The authors' findings suggest a considerable age-dependent variation with regard to anxiety and depressive disorders in adults with a cancer history. Investigation of the mechanisms contributing to this apparent age differential in risk could have important mental illness treatment implications in this population.

Lateralized periodic discharges (LPDs, also known as periodic lateralized epileptiform discharges) in conjunction with acute brain injuries are known to be associated with worse prognosis but little is known about their importance in absence of such acute injuries. We studied the clinical correlates and outcome of patients with LPDs in the absence of acute or progressive brain injury. This is a case-control study of 74 patients with no acute brain injury undergoing continuous EEG monitoring, half with LPDs and half without, matched for age and etiology of remote brain injury, if any, or history of epilepsy. Lateralized periodic discharges were found in 145/1785 (8.1%) of subjects; 37/145 (26%) had no radiologic evidence of acute or progressive brain injury. Those with LPDs were more likely to have abnormal consciousness (86% vs. 57%; P = 0.005), seizures (70% vs. 24%; P = 0.0002), and functional decline (62% vs. 27%; P = 0.005), and were less likely to be discharged home (24% vs. 62%; P = 0.002). On multivariate analysis, LPDs and status epilepticus were associated with abnormal consciousness (P = 0.009; odds ratio = 5.2, 95% CI = 1.60-20.00 and P = 0.017; odds ratio = 5.0, 95% CI = 1.4-21.4); and LPDs were independently associated with functional decline (P = 0.001; odds ratio = 4.8, 95% CI = 1.6-15.4) and lower likelihood of being discharged home (P = 0.009; odds ratio = 0.2, 95% CI = 0.04-0.6). Despite absence of acute or progressive brain injury, LPDs were independently associated with abnormal consciousness and worse outcome at hospital discharge.

Cryptosporidium infection causes gastrointestinal disease and has a worldwide distribution. The highest burden is in developing countries. We sought to conduct a systematic review and meta-analysis to identify Cryptosporidium risk factors in Low and Middle Income countries (LMICs). Medline Ovid and Scopus databases were searched with no restriction on year or language of publication. All references were screened independently in duplicate and were included if they presented data on at least 3 risk factors. Meta-analyses using random effects models were used to calculate overall estimates for each exposure. The most frequently reported risk factors in the 15 included studies were overcrowding, household diarrhoea, poor quality drinking water, animal contact, open defecation/ lack of toilet and breastfeeding. The combined odds ratio for animal contact was 1.98 (95%CI: 1.11-3.54) based on 11 studies and for diarrhoea in the household 1.98 (95%CI: 1.13-3.49) based on 4 studies. Open defecation was associated with a pooled odds ratio of 1.82 (95%CI: 1.19-2.8) based on 5 studies. Poor drinking water quality was not associated with a significant Cryptosporidium risk, odds ratio 1.06 (95%CI: 0.77-1.47). Breastfeeding was protective with pooled odds ratio 0.4 (95%CI: 0.13-1.22), which was not statistically significant. Based on the included studies, crowded living conditions, animal contact and open defecation are responsible for the majority of Cryptosporidium cases in LMICs. Future studies investigating Cryptosporidium risk factors should have a good study design and duration, include appropriate number of cases, select suitable controls, investigate multiple relevant risk factors, fully report data and perform multivariate analysis.

Several case studies have reported an association between antifungal drug use and psoriasis risk. The objective of this study was to investigate the association between terbinafine/itraconazole exposure and psoriasis incidence. Among patients with onychomycosis in the Taiwan National Health Insurance Research Database, 3831 incident psoriasis cases were identified during 2004-2010 and compared with 3831 age- and sex-matched controls with the same look-back period. Multivariate conditional logistic regression was used for the analysis. The psoriasis cases were significantly more likely than matched controls to have used terbinafine or itraconazole (59.85 vs. 42.70%, respectively; p < 0.0001). After adjusting for potential confounders and cumulative duration of antifungal drug prescription, terbinafine/itraconazole use was associated with an increased psoriasis risk (adjusted odds ratio 1.33, 95% confidence interval 1.15-1.54). The association was stronger for more recent drug exposure (adjusted odds ratio 2.96, 95% confidence interval 2.25-3.90 for ≤ 90 days before the sampling date; adjusted odds ratio 1.04, 95% confidence interval 0.89-1.22 for > 360 days). In a comparison of patients receiving terbinafine or itraconazole only, psoriasis risk was higher for itraconazole (adjusted odds ratio 1.21, 95% confidence interval 1.05-1.40). This large population-based case-control analysis showed that exposure to terbinafine or itraconazole is associated with an increased risk of incident psoriasis. The finding of an increased psoriasis risk for antifungal drug users, particularly for itraconazole, deserves attention in clinical practice although further prospective studies are necessary to confirm our findings and clarify the biological mechanisms that underlie these associations.

Disparities in access to preventive health care services among insured children in a cross sectional study.

Children with insurance have better access to care and health outcomes if their parents also have insurance. However, little is known about whether the type of parental insurance matters. This study attempts to determine whether the type of parental insurance affects the access to health care services of children.I used data from the 2009-2013 Medical Expenditure Panel Survey and estimated multivariate logistic regressions (N = 26,152). I estimated how family insurance coverage affects the probability that children have a usual source of care, well-child visits in the past year, unmet medical and prescription needs, less than 1 dental visit per year, and unmet dental needs.Children in families with mixed insurance (child publicly insured and parent privately insured) were less likely to have a well-child visit than children in privately insured families (odds ratio = 0.86, 95% confidence interval 0.76-0.98). When restricting the sample to publicly insured children, children with privately insured parents were less likely to have a well-child visit (odds ratio = 0.82, 95% confidence interval 0.73-0.92), less likely to have a usual source of care (odds ratio = 0.79, 95% confidence interval 0.67-0.94), and more likely to have unmet dental needs (odds ratio = 1.68, 95% confidence interval 1.10-2.58).Children in families with mixed insurance tend to fare poorly compared to children in publicly insured families. This may indicate that children in these families may be underinsured. Expanding parental eligibility for public insurance or subsidizing private insurance for children would potentially improve their access to preventive care.

Safety and feasibility data on transvenous lead extraction (TLE) in the challenging population of adults with congenital heart disease (A-CHD) are limited. Herein, we report the results of TLE in A-CHD during a 20-year period. All consecutive TLE procedures in A-CHD were included in a monocentric prospective registry from 1996. A total of 121 leads were extracted in 49 A-CHD (median age, 38 years; 51% men) during 71 TLE procedures. Twenty-four (49%) patients had transposition of the great arteries. Main indications for extraction were infection in 34 (48%) and lead failure in 22 (31%). A laser sheath was required for 56 (46%) leads and a femoral approach for 10 (8%). Complete TLE was achieved for 111 leads (92%). In multivariable analysis, lead duration (odds ratio, 1.02; 95% confidence interval, 1.00-1.04; P <0.01) and number of previous cardiac surgeries (odds ratio, 2.65; 95% confidence interval, 1.52-4.67; P <0.01) were predictive of TLE failure. No perioperative death or pericardial effusion was observed. Subpulmonary atrioventricular valve regurgitation increased in 8 patients (5 with transposition of the great arteries) and was independently associated with an implantable cardioverter defibrillator lead (odds ratio, 9.69; 95% confidence interval, 1.31-71.64; P =0.03) and valvular vegetation (odds ratio, 7.29; 95% confidence interval, 1.32-40.51; P =0.02). After a median of 54 (19-134) months of follow-up after the first TLE, 3 deaths occurred independently from lead management. Despite complex anatomic issues, TLE can be achieved successfully in most A-CHD using advanced extraction techniques. Subpulmonary atrioventricular valve regurgitation is a prevalent complication, particularly in patients with transposition of the great arteries. © 2018 American Heart Association, Inc.

Objectives: Associations between two alternative formulations of job stress derived from the effort-reward imbalance and the job strain model and first non-fatal acute myocardial infarction were studied. Whereas the job strain model concentrates on situational (extrinsic) characteristics the effort-reward imbalance model analyses distinct person (intrinsic) characteristics in addition to situational ones. In view of these conceptual differences the hypothesis was tested that combining information from the two models improves the risk estimation of acute myocardial infarction. Methods: 951 male and female myocardial infarction cases and 1147 referents aged 45–64 years of The Stockholm Heart Epidemiology (SHEEP) case-control study underwent a clinical examination. Information on job stress and health adverse behaviours was derived from standardised questionnaires. Results: Multivariate analysis showed moderately increased odds ratios for either model. Yet, with respect to the effort-reward imbalance model gender specific effects were found: in men the extrinsic component contributed to risk estimation, whereas this was the case with the intrinsic component in women. Controlling each job stress model for the other in order to test the independent effect of either approach did not show systematically increased odds ratios. An improved estimation of acute myocardial infarction risk resulted from combining information from the two models by defining groups characterised by simultaneous exposure to effort-reward imbalance and job strain (men: odds ratio 2.02 (95% confidence intervals (CI) 1.34 to 3.07); women odds ratio 2.19 (95% CI 1.11 to 4.28)). Conclusions: Findings show an improved risk estimation of acute myocardial infarction by combining information from the two job stress models under study. Moreover, gender specific effects of the two components of the effort-reward imbalance model were observed. PMID:11896138

Surgical site infection (SSI) contributes significantly to postoperative morbidity and mortality and greatly increases the cost of care. To identify the impact of workflow and personnel-related risk factors contributing to the incidence of SSIs in a large sample of neurological surgeries. Data were obtained using an enterprisewide electronic health record system, operating room, and anesthesia records for neurological procedures conducted between January 1, 2009, and November 30, 2012. SSI data were obtained from prospective surveillance by infection preventionists using Centers for Disease Control and Prevention definitions. A multivariate model was constructed and refined using backward elimination logistic regression methods. The analysis included 12 528 procedures. Most cases were elective (94.5%), and the average procedure length was 4.8 hours. The average number of people present in the operating room at any time during the procedure was 10.0. The overall infection rate was 2.3%. Patient body mass index (odds ratio, 1.03; 95% confidence interval [CI], 1.01-1.04) and sex (odds ratio, 1.36; 95% CI, 1.07-1.72) as well as procedure length (odds ratio, 1.19 per additional hour; 95% CI, 1.15-1.23) and nursing staff turnovers (odds ratio, 1.095 per additional turnover; 95% CI, 1.02-1.21) were significantly correlated with the risk of SSI. This study found that patient body mass index and male sex were associated with an increased risk of SSI. Operating room personnel turnover, a modifiable, work flow-related factor, was an independent variable positively correlated with SSI. This study suggests that efforts to reduce operating room turnover may be effective in preventing SSI. OR, operating roomSSI, surgical site infection.

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.

To investigate any association between dental erosion and its potential dietary risk factors in a group of schoolchildren in Benghazi, Libya. A cross-sectional observational study. A random sample of 12-year-old schoolchildren in 36 randomly selected schools completed a questionnaire to provide dietary data and underwent dental examination. Dental erosion was assessed using UK National Diet and Nutrition Survey (2000) criteria. Associations between erosion and dietary variables under study were investigated through processes of bivariate and multivariate analyses. Of 791 schoolchildren dentally examined, 40.8% had dental erosion; erosion into enamel affecting 32.5%, into dentine affecting 8% and into pulp affecting 0.3% of subjects. Bivariate analysis showed frequency of fruit-based sugary drink intake was statistically significantly and positively associated with erosion (p=0.006, Odds Ratio; 1.498, 95% CI; 1.124, 1.996) as was the length of time taken to consume acidic drinks (p≠0.005, Odds Ratio; 1.593, 95%CI; 1.161, 2.186). Additionally, multivariate analysis showed frequency of consumption of fruit other than bananas, sugared tea with milk and flavoured milk to also be positively associated with erosion (p=<0.05). In this group of Libyan 12-year-olds, frequency of consumption of fruit-based sugary drinks and length of time taken to consume acidic drinks were the primary statistically significant positive risk factors for dental erosion.

Our study aims to evaluate the association between thigh muscle cross-sectional area (TMA) using computed tomography (CT), or appendicular skeletal muscle mass (ASM) using dual energy X-ray absorptiometry (DEXA), and physical performance levels in hemodialysis (HD) patients. Patients were included if they were on HD for ≥6 months (n = 84). ASM and TMA were adjusted to body weight (BW, kg) or height2 (Ht2, m2). Each participant performed a short physical performance battery test (SPPB), a sit-to-stand for 30 second test (STS30), a 6-minute walk test (6-MWT), a timed up and go test (TUG), and hand grip strength (HGS) test. Correlation coefficients for SPPB, GS, 5STS, STS30, 6-MWT, and TUG were highest in TMA/BW. Results from partial correlation or linear regression analyses displayed similar trends to those derived from Pearson's correlation analyses. An increase in TMA/BW or TMA/Ht2 was associated with a decreased odds ratio of low SPPB, GS, or HGS in multivariate analyses. Indices using DEXA were associated with a decreased odds ratio of a low HGS only in multivariate analysis. TMA indices using CT may be more valuable in predicting physical performance or strength in HD patients. © 2017 The Author(s). Published by S. Karger AG, Basel.

Hospital-acquired Clostridium difficile infection (CDI) may cause life-threatening colitis for children with cancer, making identification of risk factors important. We described characteristics of pediatric cancer patients with primary and recurring CDI, and evaluated potential risk factors. Among 189 cancer patients, 51 cases (27%) of CDI and 94 matched controls of cancer patients without CDI were analyzed. Multivariable logistic regression was used to evaluate the association between CDI and several potential risk factors. Median age of CDI cases was lower (3.3 y; 0.60 to 16.2) than controls (7.7 y; 0.4 to 20.5). Median duration of neutropenia before CDI was longer for CDI cases (10.0 d; 0.0 to 30.0) compared with duration calculated from reference date in controls (6.0 d; 0.0 to 29.0). Multivariable analysis showed that older age was associated with reduced risk (≥7 vs. 0 to 3 y, odds ratio=0.11; 95% confidence interval, 0.02-0.54), and prolonged neutropenia was associated with increased risk (odds ratio=1.11; 95% confidence interval, 1.01-1.22). CDI recurred in 26% of cases. Younger age and prolonged neutropenia were risk factors for CDI in children with cancer. Increasing awareness to these risk factors will help to identify opportunities for CDI prevention in cancer patients.

To examine the association between physician race/ ethnicity, workplace discrimination, and physician job turnover. Cross-sectional, national survey conducted in 2006-2007 of practicing physicians (n = 529) randomly identified via the American Medical Association Masterfile and the National Medical Association membership roster. We assessed the relationships between career racial/ethnic discrimination at work and several career-related dependent variables, including 2 measures of physician turnover, career satisfaction, and contemplation of career change. We used standard frequency analyses, odds ratios and chi2 statistics, and multivariate logistic regression modeling to evaluate these associations. Physicians who self-identified as nonmajority were significantly more likely to have left at least 1 job because of workplace discrimination (black, 29%; Asian, 24%; other race, 21%; Hispanic/Latino, 20%; white, 9%). In multivariate models, having experienced racial/ethnic discrimination at work was associated with high job turnover (adjusted odds ratio, 2.7; 95% CI, 1.4-4.9). Among physicians who experienced workplace discrimination, only 45% of physicians were satisfied with their careers (vs 88% among those who had not experienced workplace discrimination, p value < .01), and 40% were contemplating a career change (vs 10% among those who had not experienced workplace discrimination, p value < .001). Workplace discrimination is associated with physician job turnover, career dissatisfaction, and contemplation of career change. These findings underscore the importance of monitoring for workplace discrimination and responding when opportunities for intervention and retention still exist.

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.

Sediment samples from nearshore sites in south San Francisco Bay and from streams flowing into that section of the Bay have been characterized in terms of their content of biogenic and anthropogenic molecular marker compounds. The distributions, input sources, and applicability of these compounds in determining sediment movement are discussed. By means of inspection and multivariate analysis, the compounds were grouped according to probable input sources and the sampling stations according to the relative importance of source contributions. A suite of polycyclic aromatic hydrocarbons (PAHs) dominated by pyrene, fluoranthene and phenanthrene, typical of estuarine environments worldwide, and suites of mature sterane and hopane biomarkers were found to be most suitable as background markers for the Bay. A homologous series of long-chain n-aldehydes (C12-C32) with a strong even-over-odd carbon number dominance in the higher molecular weight range and the ubiquitous n-alkanes (n-C24-C34) with a strong odd-over-even carbon number dominance were utilized as terrigenous markers. Several ratios of these terrigenous and Bay markers were calculated for each station. These ratios and the statistical indicators from the multivariate analysis point toward a strong terrigenous signal in the terminus of South Bay and indicate net directional movement of recently introduced sediment where nontidal currents had been considered to be minimal or nonexistent and tidal currents had been assumed to be dominant. ?? 1989.

Studies show that attendance at orthodontic appointments affects treatment outcomes, treatment duration, and the probability of side effects. The aim of this study was to predict factors that influence patients' attendance at orthodontic appointments. We conducted a face-to-face guided interview survey of 153 participants from orthodontic clinics in the Greater Boston area. Attendance at scheduled orthodontic appointments was self-reported as always, sometimes, or rarely. Participants' characteristics, including demographics, dental insurance, and oral hygiene practices, were self-reported. Moreover, from dental records, we collected the time that the participants spent undergoing active orthodontic treatment. Multivariable ordered logistic regression was used to report proportional odds ratios and attendance probabilities. A likelihood ratio test was performed to ensure that the proportional odds assumption held. For overall appointment attendance, 76% of the participants reported always attending, 16% reported sometimes attending, and 8% reported rarely attending. Based on multivariable logistic regression (adjusted for age, race, and sex), the participants with optimal oral hygiene practices were almost 6 times (5.9) more likely to attend appointments than those who did not (P = 0.002). The odds of attending appointments decreased significantly (by 23%) for every 6-month increase in treatment duration (P = 0.008). Participants covered by non-Medicaid insurance were 4 times (P = 0.018) more likely to attend appointments than were those with Medicaid insurance. Our findings indicate that adherence to orthodontic treatment follow-up visits was strongly correlated to insurance type, treatment duration, and oral hygiene practices. Unlike previous studies, sex was not a significant predictor of adherence. Copyright © 2016 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

Sleep-disordered breathing (SDB) is highly prevalent in children with Down syndrome. Given the scarcity of resources and the presence of risk factors for SDB in this population, the objective of this study is to identify the clinical predictors of SDB, which would assist prioritization of children with Down syndrome for SDB evaluation. A retrospective cohort study was conducted on children enrolled in the Down syndrome clinic at CHEO who underwent polysomnography in 2004-2014. Total apnea-hypopnea index (AHI) or obstructive AHI (OAHI) > 5 events/hour was considered clinically significant. Associations between SDB and concurrent diagnoses, referral reasons, and sleep symptoms assessed by questionnaire were examined using Pearson's chi-square test or Fisher's exact test as appropriate. Univariate and multivariate logistic regression analyses were used to examine the predictors of SDB. SDB was present in 42.9% of 119 children, with its highest prevalence at age 8 years. Symptoms were not significantly associated with AHI > 5 events/hour or OAHI > 5 events/hour. Gastroesophageal reflux was associated with lower odds of OAHI > 5 events/hour on univariate testing (odds ratio 0.16, 95% CI 0.04-0.72; p = 0.02) and multivariate analysis (odds ratio 0.05, 95% CI 0.0006-0.50; p = 0.002). SDB is highly prevalent at all ages in children with Down syndrome. Symptoms did not predict SDB in this population, although gastroesophageal reflux may mimic SDB, which indicates that clinicians should continue to perform ongoing surveillance for SDB throughout the lifespan of children with Down syndrome.

To evaluate differences in amyloid deposition in a community-based cohort without dementia by age, sex, race, education, and APOE ε4 allele status. Recruited from the longitudinal Atherosclerosis Risk in Communities study, 329 participants without dementia, ages 67-88 years, were imaged using florbetapir PET at 3 US community sites (Washington County, Maryland; Forsyth County, North Carolina; and Jackson, Mississippi). Standardized uptake value ratios (SUVRs) were calculated; global cortical SUVR >1.2 was evaluated as the primary outcome. Age, race, sex, education level, and number of APOE ε4 alleles were evaluated in multivariable models including vascular risk factors, brain white matter hyperintensity and total intracranial volume, and cognitive status. A total of 141 of the participants (43%) were black. In multivariable models, odds of elevated SUVR was increased in participants with increasing age (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.01-2.65 per 10 years of age) and black race (OR 2.08, 95% CI 1.23-3.51) but did not differ by educational level. Each ε4 allele was associated with increased odds of elevated SUVR (OR 2.65, 95% CI 1.61-4.39). In this community-based cohort without dementia, florbetapir uptake is associated with older age and APOE genotype. Black race was associated with higher SUVR, after adjusting for demographics, vascular risk factors, cognitive status, white matter hyperintensity volume, and APOE genotype, with effect sizes nearing those seen for APOE ε4. Replication of these findings is needed in other cohorts, and reasons for and consequences of these observed differences by race warrant further study. © 2016 American Academy of Neurology.

OBJECTIVE To determine whether inpatient sleep duration and efficiency are associated with a greater risk of hyperglycemia in hospitalized patients with and without diabetes. RESEARCH DESIGN AND METHODS In this retrospective analysis of a prospective cohort study, medical inpatients ≥50 years of age were interviewed, and their charts were reviewed to obtain demographic data and diagnosis. Using World Health Organization criteria, patients were categorized as having normal blood glucose, impaired fasting blood glucose, or hyperglycemia based on morning glucose from the electronic health record. Wrist actigraphy measured sleep. Multivariable ordinal logistic regression models, controlling for subject random effects, tested the association between inpatient sleep duration and proportional odds of hyperglycemia versus impaired fasting blood glucose or impaired fasting blood glucose versus normal blood glucose in hospitalized adults. RESULTS A total of 212 patients (60% female and 74% African American) were enrolled. Roughly one-third (73, 34%) had diabetes. Objective inpatient sleep measures did not differ between patients with or without diabetes. In ordinal logistic regression models, each additional hour of in-hospital sleep was associated with an 11% (odds ratio 0.89 [95% CI 0.80, 0.99]; P = 0.043) lower proportional odds of a higher glucose category the next morning (hyperglycemia vs. elevated and elevated vs. normal). Every 10% increase in sleep efficiency was associated with an 18% lower proportional odds of a higher glucose category (odds ratio 0.82 [95% CI 0.74, 0.89]; P < 0.001). CONCLUSIONS Among medical inpatients, both shorter sleep duration and worse sleep efficiency were independently associated with greater proportional odds of hyperglycemia and impaired fasting glucose.

The purposes of this study were to confirm the prognostic value of an optimal morphologic response to preoperative chemotherapy in patients undergoing chemotherapy with or without bevacizumab before resection of colorectal liver metastases (CLM) and to identify predictors of the optimal morphologic response. The study included 209 patients who underwent resection of CLM after preoperative chemotherapy with oxaliplatin- or irinotecan-based regimens with or without bevacizumab. Radiologic responses were classified as optimal or suboptimal according to the morphologic response criteria. Overall survival (OS) was determined, and prognostic factors associated with an optimal response were identified in multivariate analysis. An optimal morphologic response was observed in 47% of patients treated with bevacizumab and 12% of patients treated without bevacizumab (P < .001). The 3- and 5-year OS rates were higher in the optimal response group (82% and 74%, respectively) compared with the suboptimal response group (60% and 45%, respectively; P < .001). On multivariate analysis, suboptimal morphologic response was an independent predictor of worse OS (hazard ratio, 2.09; P = .007). Receipt of bevacizumab (odds ratio, 6.71; P < .001) and largest metastasis before chemotherapy of ≤ 3 cm (odds ratio, 2.12; P = .025) were significantly associated with optimal morphologic response. The morphologic response showed no specific correlation with conventional size-based RECIST criteria, and it was superior to RECIST in predicting major pathologic response. Independent of preoperative chemotherapy regimen, optimal morphologic response is sufficiently correlated with OS to be considered a surrogate therapeutic end point for patients with CLM.

Prior studies have reported higher inhospital mortality in women versus men with non-ST-segment-elevation myocardial infarction. Whether this is because of worse baseline risk profile compared with men or sex-based disparities in treatment is not completely understood. We queried the 2003 to 2014 National Inpatient Sample databases to identify all hospitalizations in patients aged ≥18 years with the principal diagnosis of non-ST-segment-elevation myocardial infarction. Complex samples multivariable logistic regression models were used to examine sex differences in use of an early invasive strategy and inhospital mortality. Of 4 765 739 patients with non-ST-segment-elevation myocardial infarction, 2 026 285 (42.5%) were women. Women were on average 6 years older than men and had a higher comorbidity burden. Women were less likely to be treated with an early invasive strategy (29.4% versus 39.2%; adjusted odds ratio, 0.92; 95% confidence interval, 0.91-0.94). Women had higher crude inhospital mortality than men (4.7% versus 3.9%; unadjusted odds ratio, 1.22; 95% confidence interval, 1.20-1.25). After adjustment for age (adjusted odds ratio, 0.96; 95% confidence interval, 0.94-0.98) and additionally for comorbidities, other demographics, and hospital characteristics, women had 10% lower odds of inhospital mortality (adjusted odds ratio, 0.90; 95% confidence interval, 0.89-0.92). Further adjustment for differences in the use of an early invasive strategy did not change the association between female sex and lower risk-adjusted inhospital mortality. Although women were less likely to be treated with an early invasive strategy compared with men, the lower use of an early invasive strategy was not responsible for the higher crude inhospital mortality in women, which could be entirely explained by older age and higher comorbidity burden. © 2018 American Heart Association, Inc.

Bronchiectasis develops early in the course of cystic fibrosis, being detectable in infants as young as 10 weeks of age, and is persistent and progressive. We sought to determine risk factors for the onset of bronchiectasis, using data collected by the Australian Respiratory Early Surveillance Team for Cystic Fibrosis (AREST CF) intensive surveillance program. We examined data from 127 consecutive infants who received a diagnosis of cystic fibrosis after newborn screening. Chest computed tomography (CT) and bronchoalveolar lavage (BAL) were performed, while the children were in stable clinical condition, at 3 months and 1, 2, and 3 years of age. Longitudinal data were used to determine risk factors associated with the detection of bronchiectasis from 3 months to 3 years of age. The point prevalence of bronchiectasis at each visit increased from 29.3% at 3 months of age to 61.5% at 3 years of age. In multivariate analyses, risk factors for bronchiectasis were presentation with meconium ileus (odds ratio, 3.17; 95% confidence interval [CI], 1.51 to 6.66; P=0.002), respiratory symptoms at the time of CT and BAL (odds ratio, 2.27; 95% CI, 1.24 to 4.14; P=0.008), free neutrophil elastase activity in BAL fluid (odds ratio, 3.02; 95% CI, 1.70 to 5.35; P<0.001), and gas trapping on expiratory CT (odds ratio, 2.05; 95% CI, 1.17 to 3.59; P=0.01). Free neutrophil elastase activity in BAL fluid at 3 months of age was associated with persistent bronchiectasis (present on two or more sequential scans), with the odds seven times as high at 12 months of age and four times as high at 3 years of age. Neutrophil elastase activity in BAL fluid in early life was associated with early bronchiectasis in children with cystic fibrosis.

BACKGROUND: Use of laxatives for weight loss and drugs or supplements to build muscle (eg, steroids) differs by gender and sexual orientation; little is known about factors contributing to these disparities. Conformity to gender norms concerning appearance could underlie these differences. METHODS: This study examined associations between childhood gender conformity and laxative and muscle-building product use from ages 13 to 25 years in a sample of 13 683 males and females in the US prospective Growing Up Today Study. Adjusted multivariable logistic regression models of repeated measures estimated odds of past-year laxative and muscle-building product use by quartiles of greater childhood gender conformity in heterosexual and sexual minority (eg, bisexual, gay) participants. RESULTS: By age 23 years, ∼20% of sexual minority females reported past-year laxative use. By age 19 years, 12% of all males reported past-year muscle-building product use. Sexual minority females had twice the odds of heterosexual females of using laxatives (P < .0001). The most gender-conforming females had 50% greater odds than the least-conforming females of using laxatives (P < .01). Moderate (odds ratio, 2.09; 95% confidence interval, 1.58–2.75) and highly (odds ratio, 1.79; 95% confidence interval, 1.38–2.33) gender-conforming males had higher odds than gender-nonconforming males of using muscle-building products. CONCLUSIONS: Sexual minority females are at high risk for laxative abuse. Regardless of sexual orientation, gender conformity increased the odds of laxative abuse among females and muscle-building product use among males. Findings can inform prevention efforts to target youth at risk for laxative or muscle-building product use. PMID:27418416

While the issue of sex imbalance in South Asia is well recognised, less is known about its social patterning. Social patterning in the proportion of sexes was investigated among infants in India before and after the implementation of the Pre-Natal Diagnostic Techniques (PNDT) Act in 1996. The act regulates the misuse of technologies for sex determination of fetuses and subsequent selective abortion. Multivariable regression analysis was performed on time series data from a nationally representative sample of households with infants. The outcome was log odds of having a male infant. Household income, parental education, social caste, a variable representing periods before and after the implementation of the PNDT Act and state of residence were the main predictors of interest. The odds of having a male infant increased with income quartiles. Heads of household with post-secondary education had a higher odds ratio of having a male infant than those with no formal education. The odds of having a male infant did not differ between high and low caste groups, and was not associated with the educational attainment of the spouse. Punjab had a higher odds ratio of having a male infant compared with Kerala. Kerala, meanwhile, was not particularly different from the remaining Indian states. The odds of having a male infant were similar in the pre- and post-PNDT periods. In the post-PNDT period, the income gradient in the odds of having a male infant was substantially weakened. Social analysis of the distribution of sexes among infants in India suggests that neither improvements in socioeconomic circumstances nor introducing policies that are not aligned with societal norms and preferences are likely to normalise the sex imbalance in India.

Patterns of lung cancer incidence suggest that gender-associated factors may influence lung cancer risk. Given the association of parity with risk of some women's cancers, the authors hypothesized that childbearing history may also be associated with lung cancer. Women enrolled in the Lung Cancer Susceptibility Study at Massachusetts General Hospital (Boston, Massachusetts) between 1992 and 2004 (1,004 cases, 848 controls) were available for analysis of the association between parity and lung cancer risk. Multivariate logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals. After results were controlled for age and smoking history, women with at least 1 child had 0.71 times the odds of lung cancer as women without children (odds ratio = 0.71, 95% confidence interval: 0.52, 0.97). A significant linear trend was found: Lung cancer risk decreased with increasing numbers of children (P < 0.001). This inverse association was stronger in never smokers (P = 0.12) and was limited to women over age 50 years at diagnosis (P = 0.17). Age at first birth was not associated with risk. The authors observed a protective association between childbearing and lung cancer, adding to existing evidence that reproductive factors may moderate lung cancer risk in women.

Objective The aim of this study was to examine racial/ethnic differences in fifth grade children’s mental health care utilization. Methods We analyzed cross-sectional data from a study of 5147 fifth graders and their parents in 3 US metropolitan areas from 2004–06. Multivariate logistic regression was used to examine racial/ethnic differences in mental health care utilization. Results Nine percent of parents reported that their child had ever used mental health care services; fewer black (6%) and Hispanic (8%) children had used services than white children (14%). Fewer black and Hispanic children with recent symptoms of attention-deficit/hyperactivity disorder, oppositional defiant disorder, and conduct disorder, and fewer black children with symptoms of depression had ever utilized services compared with white children. In multivariate analyses controlling for demographic factors, parental mental health, social support, and symptoms of the 4 mental health conditions, we found that black children were less likely than white children to have ever used services (Odds ratio [OR] 0.3, 95% confidence interval [95% CI], 0.2–0.4, P <.001). The odds ratio for black children remained virtually unchanged when the analysis was restricted to children with symptoms of ≥1 mental health condition, and when the analysis was stratified by mental health condition. The difference in utilization for Hispanic compared with white children was fully explained by sociodemographics in all multivariate models. Conclusions Disparities exist in mental health care utilization for black and Hispanic children; the disparity for black children is independent of sociodemographics and child mental health need. Efforts to reduce this disparity may benefit from addressing not only access and diagnosis issues, but also parents’ help-seeking preferences for mental health care for their children. PMID:19329099

We measured the prevalence of active epilepsy and investigated the treatment gap and treatment gap risk profile in eastern China. This was a cross-sectional population-based survey conducted in Zhejiang, China, from October 2013 to March 2014. A total 54,976 people were selected using multi-stage cluster sampling. A two-stage questionnaire-based process was used to identify patients with active epilepsy and to record their demographic, socioeconomic, and epilepsy-related features. Logistic regression analysis was used to analyze risk factors of the treatment gap in eastern China, as adjusted for age and sex. We interviewed 50,035 people; 118 had active epilepsy (2.4‰), among which the treatment gap was 58.5%. In multivariate analysis, failure to receive appropriate antiepileptic treatment was associated with higher seizure frequency of 12-23 times per year (adjusted odds ratio=6.874; 95% confidence interval [CI]=2.372-19.918), >24 times per year (adjusted odds ratio=19.623; 95% CI=4.999-77.024), and a lack of health insurance (adjusted odds ratio=7.284; 95% CI=1.321-40.154). Eastern China has relatively lower prevalence of active epilepsy and smaller treatment gap. Interventions aimed at reducing seizure frequency, improving the health insurance system should be investigated as potential targets to further bridge the treatment gap.

China is undergoing a rapid transition to an urbanized and Western diet pattern, which worsens the public health burden of metabolic syndrome (MS) and chronic kidney disease (CKD). We aimed to estimate the prevalence of CKD among adults with MS and to evaluate the association between MS and CKD in China. The data were obtained from the China National Diabetes and Metabolic Disorders Study conducted from June 2007 to May 2008. A total of 15,987 individuals aged 20 y or older were included as study participants. Age-standardized prevalence of CKD, which was defined as a glomerular filtration rate <60 ml/min/1.73 m(2), in participants with and without MS was 4.64% and 3.30%, respectively. The multivariate-adjusted odds ratio of CKD associated with MS was 1.495 (95% CI: 1.190-1.879). Elevated blood pressure, elevated fasting glucose, elevated triglycerides, and reduced high-density lipoprotein cholesterol had statistically significant increased odds ratios of 1.218, 1.256, 1.325 and 1.797 for CKD, respectively, while elevated waist circumference was not significantly associated with an increased odds ratio of CKD. Our study suggests an increasing prevalence of CKD among Chinese adults with MS and a strong association between CKD and MS. Copyright © 2014 The Authors. Published by Elsevier B.V.

The seroepidemiology of Entamoeba histolytica infection in Tepehuanos population in Mexico is largely unknown. This study aimed to study the seroprevalence and correlates of E. histolytica antibodies in Tepehuanos in Durango, Mexico. Through a cross-sectional study, we determined the frequency of E. histolytica IgG antibodies in 156 Tepehuanos people in Durango, Mexico using an enzyme-linked immunoassay. Furthermore, we studied the association of E. histolytica seroprevalence with the socio-demographic, clinical, and behavioral characteristics of the Tepehuanos studied. Forty-four (28.2%) Tepehuanos with mean age of 31.03 ± 16.71 years old had anti- E. histolytica IgG antibodies. Multivariate analysis showed that E. histolytica exposure was positively associated with laborer occupation (Odds ratio=2.77; 95% CI: 1.15, 6.66; p=0.02), and history of lymphadenopathy (Odds ratio=4.97; 95% CI: 1.74, 14.13; p=0.002), and negatively associated with soil contact (Odds ratio=0.13; 95% CI: 0.03, 0.53; p=0.004). Other behavioral characteristics including drinking untreated water or unpasteurized milk, and consumption of unwashed raw vegetables or fruits were not associated with E. histolytica exposure. The seroprevalence of E. histolytica infection in Tepehuanos in Durango is higher thanseroprevalences reported in national surveys. The factors associated with E. histolytica seropositivity reported in the present study might aid for the planning and implementation of effective measures against E. histolytica infection.

A four-fold increase of suicide mortality has been demonstrated in systemic lupus erythematosus (SLE) patients. Prior studies showed that the most common method of suicide attempts in SLE patients involves drug overdose. Therefore, we conducted a nationwide population-based case-control study to elucidate factors associated with drug overdose as suicide attempt in SLE patients. This study was based on the National Health Insurance Research Database in Taiwan. We identified all SLE patients from January 1, 2000 to December 31, 2010. Patients who had suicidal drug overdose (SDO) were selected as cases while age- and gender-matched patients who did not have SDO were selected as controls. The incidence rate of SDO in SLE patients was 291 cases per 100,000 person-years, higher than that in the general population (160 cases per 100,000 person-years). In a multivariate logistic regression analysis, we observed that SDO was associated with psychiatric disorders such as depressive disorders (odds ratio: 8.36, 95% confidence interval (CI): 5.60-12.48) and insomnia (odds ratio: 2.71, 95% CI: 1.73-4.25), and lower monthly income (odds ratios: 2.74 to 3.50) in SLE patients. SDO is associated with psychiatric disorders such as depressive disorders and insomnia, and lower monthly income in SLE patients. © The Author(s) 2015.

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

Sleep apnea (SA) has been linked with various forms of cardiovascular disease, but little is known about its association with peripheral artery disease (PAD) measured using the ankle-brachial index. This relationship was evaluated in the Hispanic Community Health Study/Study of Latinos. We studied 8367 Hispanic Community Health Study/Study of Latinos participants who were 45 to 74 years of age. Sleep symptoms were examined with the self-reported Sleep Health Questionnaire. SA was assessed using an in-home sleep study. Systolic blood pressure was measured in all extremities to compute the ankle-brachial index. PAD was defined as ankle-brachial index <0.90 in either leg. Multivariable logistic regression was used to investigate the association between moderate-to-severe SA, defined as apnea-hypopnea index ≥15, and the presence of PAD. Analyses were adjusted for covariates. The prevalence of PAD was 4.7% (n=390). The mean apnea-hypopnea index was significantly higher among adults with PAD compared with those without (11.1 versus 8.6 events/h; P=0.046). After adjusting for covariates, moderate-to-severe SA was associated with a 70% increase in the odds of PAD (odds ratio, 1.7; 95% confidence interval, 1.1-2.5; P=0.0152). This association was not modified by sex (P=0.8739). However, there was evidence that the association between moderate-to-severe SA and PAD varied by Hispanic/Latino background (P<0.01). Specifically, the odds were stronger in Mexican (adjusted odds ratio, 2.9; 95% confidence interval, 1.3-6.2) and in Puerto Rican Americans (adjusted odds ratio, 2.0; 95% confidence interval, 0.97-4.2) than in other backgrounds. Moderate-to-severe SA is associated with higher odds of PAD in Hispanic/Latino adults. © 2015 American Heart Association, Inc.

Delusional jealousy (DJ) has been described in patients with Parkinson's disease (PD) on dopaminergic therapy, but a role for dopaminergic therapy in DJ has not been established. The current cross-sectional study on DJ investigated its association with dopaminergic therapies compared with their associations with hallucinations and its prevalence in PD patients. Eight hundred five consecutive patients with PD were enrolled between January 2009 and June 2010. DJ was identified in 20 patients (2.48%) and hallucinations in 193 patients (23.98%). In the multivariate logistic regression analyses, dopamine agonists were significantly associated with DJ (odds ratio, 18.1; 95% CI, 3.0-infinity; P = .0002) but not with hallucinations (odds ratio, 0.73; 95% CI, 0.49-1.10; P = .133). These findings suggest that dopamine agonist treatment represents a risk factor for DJ in PD independent of the presence of a dementing disorder, and the presence of this additional nonmotor side effect should be investigated in this clinical population.

Tobacco use is high among US extraction and construction workers, who can also incur occupational dust exposure. Information on different types of tobacco use among quarry/mine workers is sparse. During mandated training sessions, New Jersey quarry workers were surveyed about their tobacco use. Prevalence was calculated for single and multiple tobacco use by demographic and workplace characteristics; logistic regression was used to assess associations with smoking. Two hundred forty (97.1%) workers completed surveys. Among respondents, 41.7% [95% confidence interval (95% CI) 35.4 to 48.3] currently used any tobacco product of whom 28.1% smoked cigarettes. In multivariate analysis, positive associations with smoking included working as a contractor versus mine employee (odds ratio 2.32, 95% CI 1.01 to 5.36) and a usual job title of maintenance (odds ratio 2.02, 95% CI 0.87 to 4.94). Industry-specific information may be helpful in developing targeted tobacco-cessation programs.

Factors influencing the neonatal therapeutic effect of anti-MRSA (methicillin-resistant Staphylococcus aureus) drugs are investigated. This study took place over a two-year period from April 1998 to March 2000. We calculated the non-adjusted odds ratio for each influential factor to determine the therapeutic effect of anti-MRSA drugs. Significant factors for therapeutic effect were found to be platelet count, urea nitrogen, creatinine, and CRP, each measured before starting administration of anti-MRSA drugs; whether blood drug concentration was measured; and whether pneumonia or septicemia was present. There was a tendency where a better therapeutic effect was gained when the total protein and albumin values were high. We applied multivariate logistic regression analysis to these factors, and found the following independent significant factors: CRP (odds ratio (OR) = 1.582), albumin (OR = 3.079), Cre (OR -0.213), whether blood drug concentration was measured (OR = 3.767), and presence of pneumonia or septicemia (OR = 0.216). This result suggests that consideration should be given to these five important factors when treating MRSA patients.

We examined factors related to pilot survival in 167 consecutive helicopter commuter and air taxi crashes that occurred during 1983-88. Case fatality rates and adjusted odds ratios from multivariate logistic regression models were determined using data from the National Transportation Safety Board (NTSB). During this 6-year period, 29 pilots-in-command died in 167 helicopter commuter and air taxi crashes, a case fatality rate of 17.4%. Factors significantly associated with increased risk of pilot fatality were aircraft fire [odds ratio (OR) 20.0, 95% confidence interval (CI) 4.6-86.8], not using shoulder harnesses (OR 9.2, 95% CI 2.2-37.3), and aircraft with two engines (OR 4.8, 95% CI 1.3-17.4). In addition, we present data regarding success and failure of emergency flotation devices. The results suggest that the likelihood of pilot survival in helicopter crashes could be greatly improved by preventing crash associated fires and promoting the usage of shoulder restraints.

Objective To determine the association between antenatal steroids administration and intraventricular hemorrhage rates. Methods We used cross-sectional data from the California Perinatal Quality Care Collaborative during 2007-2013 for infants ≤ 32 weeks gestational age. Using multivariable logistic regression, we evaluated the effect of antenatal steroids on intraventricular hemorrhage, stratified by gestational age. Results In 25,979 very low birth weight infants, antenatal steroid use was associated with a reduction in incidence of any grade of intraventricular hemorrhage (odds ratio = 0.51, 95% confidence interval: 0.45, 0.58) and a reduction in incidence of severe intraventricular hemorrhage (odds ratio = 0.62, 95% confidence interval: 0.57, 0.67). This association was seen across gestational ages ranging from 22 to 29 weeks. Conclusions While current guidelines recommend coverage for preterm birth at 24 to 34 weeks gestation, our results suggest that treatment with antenatal steroids may be beneficial even before 24 weeks of gestational age.

Objectives: We aimed to investigate the health inequity of victims of occupational accidents through the association between socioeconomic status and unmet healthcare need. Methods: Data from the first and second Panel Study of Workers' Compensation Insurance were used, which included 1,803 participants. The odds ratio and 95% confidence intervals for the unmet healthcare needs of participants with a lower socioeconomic status and other socioeconomic statuses were investigated using multivariate regression analysis. Results: Among all participants, 103 had unmet healthcare needs, whereas 1,700 did not. After adjusting for sex, age, smoking, alcohol, chronic disease, recuperation duration, accident type, disability, and economic participation, the odds ratio of unmet healthcare needs in participants with a lower socioeconomic status was 2.04 (95% confidence interval 1.32-3.15) compared to participants with other socioeconomic statuses. Conclusions: The victims of occupational accidents who have a lower socioeconomic status are more likely to have unmet healthcare needs in comparison to those with other socioeconomic statuses.

To investigate whether work engagement influences self-perceived health, work ability, and sickness absence beyond health behaviors and work-related characteristics. Employees of two organizations participated in a 6-month longitudinal study (n = 733). Using questionnaires, information was collected on health behaviors, work-related characteristics, and work engagement at baseline, and self-perceived health, work ability, and sickness absence at 6-month follow-up. Associations between baseline and follow-up variables were studied using multivariate and multinomial logistic regression analyses and changes in R2 were calculated. Low work engagement was related with low work ability (odds ratio: 3.68; 95% confidence interval: 2.15 to 6.30) and long-term sickness absence (odds ratio: 1.84; 95% confidence interval: 1.04 to 3.27). Work engagement increased the explained variance in work ability and sickness absence with 4.1% and 0.5%, respectively. Work engagement contributes to work ability beyond known health behaviors and work-related characteristics.

Brazil has the sixth largest bicycles fleet in the world and bicycle is the most used individual transport vehicle in the country. Few studies address the issue of cyclists' accidents and factors that contribute to or prevent this event. VIVA is a cross-sectional survey and is part of the Violence and Accidents Surveillance System, Brazilian Ministry of Health. We used complex sampling and subsequent data review through multivariate logistic regression and calculation of the respective odds ratios. Odds ratios showed greater likelihood of cyclists' accidents in males, people with less schooling and living in urban and periurban areas. People who were not using the bike to go to work were more likely to suffer an accident. The profile found in this study corroborates findings of other studies. They claim that the coexistence of cyclists and other means of transportation in the same urban space increases the likelihood of accidents. The construction of bicycle-exclusive spaces and educational campaigns are required.

There has been increasing evidence that ascending thoracic aortic aneurysms (TAAs) protect against atherosclerosis. However, there have been no studies examining the relationship between ascending TAAs and clinical endpoints of atherosclerosis, such as stroke or peripheral arterial disease. In this study, we aim to characterize the relationship between TAAs and a specific clinical endpoint of atherosclerosis, myocardial infarction (MI). We compared prevalence of coronary artery disease (CAD) and MIs in 487 patients who underwent surgical repair for ascending TAAs to 500 control patients who did not have an ascending TAA. Multivariate binary logistic regression was used to calculate the odds of having MI if a patient had an ascending TAA versus any of several MI risk factors. There was a significantly lower prevalence of CAD and MI in the ascending TAA group than in the control TAA group. The odds of having a MI if a patient had a MI risk factor were all > 1 (more likely to have a MI), with the lowest statistically significant odds ratio being 1.54 (age; p = 0.001) and the highest being 14.9 (family history of MI; p < 0.001). The odds ratio of having a MI if a patient had an ascending TAA, however, was near 0 at 0.05 (p < 0.001). This study provides evidence that ascending TAAs protect against MIs, adding further support to the hypothesis that ascending TAAs protect against atherosclerotic disease.

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.

Consuming a variety (vs. monotony) of energy-poor, nutrient-dense foods may help individuals adhere to dietary patterns favorably associated with weight control. The objective of this study was to examine whether greater healthful food variety quantified using the US Healthy Food Diversity (HFD) index favorably influenced body adiposity. Men and nonpregnant, nonlactating women aged ≥20 y with two 24-h recalls from the cross-sectional NHANES 2003-2006 (n = 7470) were included in this study. Dietary recalls were merged with the MyPyramid Equivalent database to generate the US HFD index, which ranges from 0 to ∼1, with higher scores indicative of diets with a higher number and proportion of healthful foods. Multiple indicators of adiposity including BMI, waist-to-height ratio, android-to-gynoid fat ratio, fat mass index (FMI), and percentage body fat were assessed across US HFD index quintiles. ORs and 95% CIs were computed with use of multivariable logistic regression (SAS v. 9.3). The US HFD index was inversely associated with most adiposity indicators in both sexes. After multivariable adjustment, the odds of obesity, android-to-gynoid ratio >1, and high FMI were 31-55% lower (P-trend < 0.01) among women in quintile 5 vs. quintile 1 of the US HFD index. Among men, the odds of obesity, waist-to-height ratio ≥0.5, and android-to-gynoid ratio >1 were 40-48% lower (P-trend ≤ 0.01) in quintile 5 vs. quintile 1 of the US HFD index. Higher US HFD index values were inversely associated with indicators of body adiposity in both sexes, indicating that greater healthful food variety may protect against excess adiposity. This study explicitly recognizes the potential benefits of dietary variety in obesity management and provides the foundation to support its ongoing evaluation. © 2015 American Society for Nutrition.

Summary Background and objectives There exists gross disparity in national deceased donor kidney transplant availability and practice: waiting times exceed 6 years in some regions, but some patients receive kidneys before they require dialysis. This study aimed to quantify and characterize preemptive deceased donor kidney transplant recipients and compare their outcomes with patients transplanted shortly after dialysis initiation. Design, setting, participants, & measurements Using the Scientific Registry of Transplant Recipients database, first-time adult deceased donor kidney transplant recipients between 1995 and 2011 were classified as preemptive, early (on dialysis≤1 year), or late recipients. Random effects logistic regression and multivariate Cox proportional hazards regression were used to identify characteristics of preemptive deceased donor kidney transplant and evaluate survival in preemptive and early recipients, respectively. Results Preemptive recipients were 9.0% of the total recipient population. Patients with private insurance (adjusted odds ratio=3.15, 95% confidence interval=3.01–3.29, P<0.001), previous (nonkidney) transplant (adjusted odds ratio=1.94, 95% confidence interval=1.67–2.26, P<0.001), and zero-antigen mismatch (adjusted odds ratio=1.45, 95% confidence interval=1.37–1.54, P<0.001; Caucasians only) were more likely to receive preemptive deceased donor kidney transplant, even after accounting for center-level clustering. African Americans were less likely to receive preemptive deceased donor kidney transplant (adjusted odds ratio=0.44, 95% confidence interval=0.41–0.47, P<0.001). Overall, patients transplanted preemptively had similar survival compared with patients transplanted within 1 year after initiating dialysis (adjusted hazard ratio=1.06, 95% confidence interval=0.99–1.12, P=0.07). Conclusions Preemptive deceased donor kidney transplant occurs most often among Caucasians with private insurance, and survival is fairly similar to survival of recipients on dialysis for <1 year.

Appearance concerns are common in systemic sclerosis (SSc) and have been linked to younger age and more severe disease. No study has examined their association with sex or race/ethnicity. SSc patients were sampled from the Scleroderma Patient-centered Intervention Network Cohort. Presence of appearance concerns was assessed with a single item, and medical and sociodemographic information were collected. Of 644 patients, appearance concerns were present in 72%, including 421 of 565 women (75%), 42 of 79 men (53%), 392 of 550 patients who identified as White (71%), 35 of 41 who identified as Black (85%), and 36 of 53 who identified as another race/ethnicity (68%). In multivariate analysis, women had significantly greater odds of reporting appearance concerns than men (odds ratio (OR)=2.97, 95% confidence interval (CI)=1.78-4.95, p<.001). Black patients had significantly greater odds of appearance concerns than White patients in unadjusted (OR=2.64, 95% CI=1.01-6.34, p=.030), but not multivariate analysis (OR=1.76, 95% CI=0.67-4.60, p=.250). Compared to a general population sample, appearance concerns were substantially more common in SSc, particularly for men across all age groups and for younger women. The most commonly reported features of concern were related to the face and head, followed by the hands and fingers; this did not differ by sex or race/ethnicity. Appearance concerns were common in SSc. Women were substantially more likely than men to have appearance concerns. Although non-significant in multivariate analysis, Black patients were more likely to have concerns than White patients, likely due to more severe changes in appearance.

Little evidence within plastic surgery literature supports the precept that longer operative times lead to greater morbidity. The authors investigate surgery duration as a determinant of morbidity, with the goal of defining a clinically relevant time for increased risk. A retrospective chart review was conducted of patients who underwent a broad range of complex plastic surgical procedures (n = 1801 procedures) at UT Southwestern Medical Center in Dallas, Texas, from January 1, 2008 to January 31, 2012. Adjusting for possible confounders, multivariate logistic regression assessed surgery duration as an independent predictor of morbidity. To define a cutoff for increased risk, incidence of complications was compared among quintiles of surgery duration. Stratification by type of surgery controlled for procedural complexity. A total of 1753 cases were included in multivariate analyses with an overall complication rate of 27.8%. Most operations were combined (75.8%), averaging 4.9 concurrent procedures. Each hour increase in surgery duration was associated with a 21% rise in odds of morbidity (P < .0001). Compared with the first quintile of operative time (<2.0 hours), there was no change in complications until after 3.1 hours of surgery (odds ratio, 1.6; P = .017), with progressively greater odds increases of 3.1 times after 4.5 hours (P < .0001) and 4.7 times after 6.8 hours (P < .0001). When stratified by type of surgery, longer operations continued to be associated with greater morbidity. Surgery duration is an independent predictor of complications, with a significantly increased risk above 3 hours. Although procedural complexity undoubtedly affects morbidity, operative time should factor into surgical decision making.

Research on the association between periodontitis and oral human papilloma virus (HPV) infection is inconsistent. The cross-sectional association of severe periodontitis with oral HPV infection was investigated in a sample of Hispanic adults. Data from the 2014-2016 San Juan Overweight Adults Longitudinal Study (n = 740) was analyzed. Periodontitis assessment and self-collection of oral HPV samples followed the National Health and Nutrition Examination Survey methodology. Periodontitis was defined using the Centers of Disease Control and Prevention/American Academy of Periodontology definition. HPV typing was performed using polymerase chain reaction. Multivariate logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). 5.7% of participants had oral HPV infection and 20.3% had severe periodontitis. Adults with severe periodontitis had higher odds of oral HPV infection than those with none/mild disease (OR=2.9, 95% CI: 1.0-8.4, p < 0.05) in multivariable analysis. Adults with clinical attachment loss≥ 7 mm and pocket depth PD≥ 6 mm had 2- to 3-fold higher odds of HPV infection. Severe periodontitis was positively associated to oral HPV infection. Longitudinal evaluation of periodontal inflammation's role in acquisition and persistence of oral HPV infection is needed, as periodontitis screening could identify individuals at increased risk of HPV-related oral malignancies.

Household related predictors of burn injuries in an Iranian population: a case–control study

PubMed Central

2012-01-01

Background To prevent burn injuries it is vital to have sound information on predictors of its occurrence in different settings. Ardabil Province is the coldest province of Iran with high burden of burn injuries. The aim of this study was to determine the household related predictors of unintentional burns in Ardabil Province located at North-West of Iran. Methods The study was conducted through a hospital based case–control design. 239 burn victims as well as 246 hospital-based controls were enrolled. Both bivariate and multivariate analysis methods were used. Results Males comprised 55.2% of all the study subjects. Mean age of the participants was 21.8 years (95% CI: 19.17-24.4). The economic ability of the households was associated with risk of burn injuries. Multivariate conditional logistic regression results showed the following variables to be independent factors associated with burn injuries. Using non-conventional pipe-less air heaters instead of conventional piped kerosene- or gas-burning heaters (Odds ratio: 1.98, 95% CI: 1.1-3.6). Common use of picnic gas-stove for cooking at home (odds ratio = 1.6, 95%CI: 1–2.4). Using electric samovars instead of other types of samovars (Odds ratio = 0.3, 95% CI: 0.1-1). Using samovars lacking the national standard authorization mark (Odds ratio = 2.2, 95% CI: 1.4-3.6). Conclusion Using some types of specific heating or cooking appliances, and unsafe use of conventional appliances were major risk predictors of burn injuries in this population. PMID:22571762

To investigate the factors related to the 1-month period prevalence of low back pain (LBP), neck pain (NP) and thoracic spine pain (TSP) in young adolescents, thereby considering potential correlates from the physical, sociodemographic, lifestyle, psychosocial and comorbid pain domains. In this cross-sectional baseline study, 69 factors potentially associated with spinal pain were assessed among 842 healthy adolescents before pubertal peak growth. With consideration for possible sex differences in associations, multivariable analysis was used to simultaneously evaluate contributions of all variables collected in the five domains. A significantly higher odds of LBP was shown for having high levels of psychosomatic complaints (odds ratio: 4.4; 95 % confidence interval: 1.6-11.9), a high lumbar lordotic apex, retroversed pelvis, introverted personality, and high levels of negative over positive affect. Associations with a higher prevalence and odds of NP were found for psychosomatic complaints (7.8; 2.5-23.9), TSP in the last month (4.9; 2.2-10.8), backward trunk lean, high levels of negative over positive affect and depressed mood. Having experienced LBP (2.7; 1.3-5.7) or NP (5.5; 2.6-11.8) in the preceding month was associated with a higher odds of TSP, as were low self-esteem, excessive physical activity, sedentarism and not achieving the Fit-norm. Psychosomatic symptoms and pain comorbidities had the strongest association with 1-month period prevalence of spinal pain in young adolescents, followed by factors from the physical and psychosocial domains. The role that "physical factors" play in non-adult spinal pain may have been underestimated by previous studies.

Background Despite numerous trials assessing optimal antibiotic prophylaxis strategies for colorectal surgery, few studies have assessed real-world practice on a national scale with respect to risk of surgical site infections. Objective Using a large, national claims database we aimed to describe 1) current use of prophylactic antibiotics (type and duration) and 2) associations with surgical site infection after open colectomies. Design Retrospective study using the Premier Perspective database. Setting Patient hospitalizations nationwide from January 2006 to December 2013. Patients 90,725 patients that underwent an open colectomy in 445 different hospitals. Main Outcome Measures Multilevel multivariable logistic regressions measured associations between surgical site infection and 1) type of antibiotic used and 2) duration (day of surgery only, day of surgery and the day after, >1 day after surgery). Results Overall surgical site infection prevalence was 5.2% (n=4,750). Most patients (41.8%) received cefoxitin for prophylaxis; other choices were ertapenem (18.2%), cefotetan (10.3%), metronidazole+cefazolin (9.9%), ampicillin+sulbactam (7.6%), while 12.2% received other antibiotics. Distribution of prophylaxis duration was: 51.6%, 28.5%, and 19.9% for days 0, 0+1, and 1+, respectively. Compared to cefoxitin, lower odds for surgical site infection were observed for ampicillin+sulbactam (odds ratio 0.71; 95% confidence interval 0.63–0.82), ertapenem (odds ratio 0.65; 95% confidence interval 0.58–0.71) and metronidazole+cefazolin (odds ratio 0.56; 95% confidence interval 0.49–0.64), and “other” (odds ratio 0.81; 95% confidence interval 0.73–0.90); duration was not significantly associated with altered odds for surgical site infection. Sensitivity analyses supported the main findings. Limitations Lack of detailed clinical information in the billing dataset used. Conclusions In this national study assessing real-world use of prophylactic antibiotics in open colectomies, type of antibiotic used appeared to be associated with up to 44% decreased odds for surgical site infections. While there are numerous trials on optimal prophylactic strategies, studies that particularly focus on factors that influence the choice of prophylactic antibiotic might provide insights into ways of reducing the burden of surgical site infections in colorectal surgeries.

Little is known about residence in a rural or farming environment and allergic diseases in Latin America. Cross-sectional study of rural residence and current wheeze, current asthma and current symptoms of allergic rhino-conjunctivitis in 1,804 adolescents (ages 13-14 years) attending 31 schools in urban and rural areas of San Francisco (Córdoba, Argentina). Rural residence was classified as never, previous, and current. Duration of rural residence was categorized as 0, >0 but ≤5 years, and >5 years. Current wheeze, current asthma, and current allergic rhino-conjunctivitis were defined on the basis of responses to an extensively validated questionnaire from the International Study of Asthma and Allergies in Childhood. Logistic regression was used for the multivariable analysis of rural residence and the outcomes of interest. After adjustment for current smoking and other covariates, current rural residence (odds ratio [OR] = 0.15, 95% confidence interval [CI] = 0.03-0.81) and rural residence for >5 years (OR = 0.32, 95%CI = 0.12-0.84) were significantly associated with reduced odds of current wheeze. In a multivariable analysis, current residence in a rural area (OR = 0.52, 95%CI = 0.32-0.86) and rural residence for >5 years (OR = 0.44, 95%CI = 0.26-0.73) were significantly associated with reduced odds of allergic rhino-conjunctivitis. This association was no longer significant after additional adjustment for current residence in a dairy farm, which was significantly associated with reduced odds of allergic rhino-conjunctivitis. Similarly, current regular contact with farm animals was significantly associated with reduced odds of allergic rhino-conjunctivitis. Among Argentinean adolescents, current rural residence and rural residence for >5 years were associated with reduced odds of current wheeze and allergic rhino-conjunctivitis. These potential protective effects may be explained by a dairy farm environment, including regular contact with farm animals.

It is unclear whether persistent prehypertension causes structural or functional alterations of the heart. We examined echocardiographic data of 1005 adults from a population-based survey at baseline in 1994/1995 and at follow-up in 2004/2005. We compared individuals who had either persistently normal (<120 mmHg systolic and <80 mmHg diastolic, n = 142) or prehypertensive blood pressure (120-139 mmHg or 80-89 mmHg, n = 119) at both examinations using multivariate regression modeling. Over 10 years, left ventricular end-diastolic diameters were stable and did not differ between the two groups. However, the prehypertensive blood pressure group displayed more pronounced ageing-related increases of left ventricular wall thickness (+4.7 versus +11.9%, P < 0.001) and left ventricular mass (+8.6 versus +15.7%, P = 0.006). Prehypertension was associated with a raised incidence of left ventricular concentric remodeling (adjusted odds ratio 10.7, 95% confidence interval 2.82-40.4) and left ventricular hypertrophy (adjusted odds ratio 5.33, 1.58-17.9). The ratio of early and late diastolic peak transmitral flow velocities (E/A) decreased by 7.7% in the normal blood pressure versus 15.7% in the prehypertensive blood pressure group (P = 0.003) and at follow-up the ratio of early diastolic peak transmitral flow and early diastolic peak myocardial relaxation velocities (E/EM) was higher (9.1 versus 8.5, P = 0.031) and left atrial size was larger (36.5 versus 35.3 mm, P = 0.024) in the prehypertensive blood pressure group. Finally, the adjusted odds ratio for incident diastolic dysfunction was 2.52 (1.01-6.31) for the prehypertensive blood pressure group. Persistent prehypertension accelerates the development of hypertrophy and diastolic dysfunction of the heart.

Summary Background and objectives Awareness of chronic kidney disease (CKD) among providers and patients is low. Whether clinical cues prompt recognition of CKD is unknown. We examined whether markers of kidney disease that should trigger CKD recognition among providers are associated with higher individual CKD awareness. Design, setting, participants, & measurements CKD awareness was assessed in 1852 adults with an estimated GFR <60 ml/min per 1.73 m2 using 1999 to 2008 National Health and Nutrition Examination Survey data. CKD awareness was a “yes” answer to “Have you ever been told you have weak or failing kidneys?” Participants were grouped by distribution of the following abnormal markers of CKD: hyperkalemia, acidosis, hyperphosphatemia, elevated blood urea nitrogen, anemia, albuminuria, and uncontrolled hypertension. Odds of CKD awareness associated with each abnormal marker and groupings of markers were estimated by multivariable logistic regression. Results Among individuals with kidney disease, only those with albuminuria had greater odds of CKD awareness (adjusted odds ratio, 4.0, P < 0.01) than those without. Odds of CKD awareness increased with each additional manifested clinical marker of CKD (adjusted odds ratio, 1.3, P = 0.05). Nonetheless, 90% of individuals with two to four markers of CKD and 84% of individuals with ≥5 markers of CKD were unaware of their disease. Conclusions Although individuals who manifest many markers of kidney dysfunction are more likely to be aware of their CKD, their CKD awareness remains low. A better understanding of mechanisms of awareness is required to facilitate earlier detection of CKD and implement therapy to minimize associated complications. PMID:21784832

Leisure-time physical activity protects from stroke. It is insufficiently established whether early lifetime physical activity is independently protective and whether some etiologic stroke subgroups particularly benefit from physical activity. We tested the hypothesis that both recent and early-adulthood sports activities are associated with reduced odds of stroke and analyzed their effects in stroke subtypes. We performed a case-control study of 370 patients with acute stroke or transient ischemic attack (TIA) and 370 age- and sex-matched control subjects randomly selected from the population and assessed recent and young adulthood sports activities and their weekly duration in standardized interviews. Recent regular sports activities were less often reported by patients (94/370, 25.4%) than by control subjects (162/370, 43.8%; P<0.0001). After adjustment for vascular risk factors, education, and other factors, recent participation in sports was significantly associated with reduced odds of stroke/TIA (odds ratio=0.64; 95% CI, 0.43 to 0.96). Both groups did not differ with regard to sports activities in young adulthood. More control subjects (69/365, 18.9%) than patients (25/361, 6.9%) participated in sports recently after not having been active in young adulthood, and such a pattern was associated with reduced odds of stroke/TIA in multivariable analysis (odds ratio=0.37; 95% CI, 0.21 to 0.85). Our study supports previous results that have shown stroke protection by physical activity. Results suggest that continuous lifetime activity or starting activities during later adulthood is required to reduce stroke risk.

The American College of Surgeons and the American Geriatrics Society have suggested that preoperative cognitive screening should be performed in older surgical patients. We hypothesized that unrecognized cognitive impairment in patients without a history of dementia is a risk factor for development of postoperative complications. We enrolled 211 patients 65 yr of age or older without a diagnosis of dementia who were scheduled for an elective hip or knee replacement. Patients were cognitively screened preoperatively using the Mini-Cog and demographic, medical, functional, and emotional/social data were gathered using standard instruments or review of the medical record. Outcomes included discharge to place other than home (primary outcome), delirium, in-hospital medical complications, hospital length-of-stay, 30-day emergency room visits, and mortality. Data were analyzed using univariate and multivariate analyses. Fifty of 211 (24%) patients screened positive for probable cognitive impairment (Mini-Cog less than or equal to 2). On age-adjusted multivariate analysis, patients with a Mini-Cog score less than or equal to 2 were more likely to be discharged to a place other than home (67% vs. 34%; odds ratio = 3.88, 95% CI = 1.58 to 9.55), develop postoperative delirium (21% vs. 7%; odds ratio = 4.52, 95% CI = 1.30 to 15.68), and have a longer hospital length of stay (hazard ratio = 0.63, 95% CI = 0.42 to 0.95) compared to those with a Mini-Cog score greater than 2. Many older elective orthopedic surgical patients have probable cognitive impairment preoperatively. Such impairment is associated with development of delirium postoperatively, a longer hospital stay, and lower likelihood of going home upon hospital discharge.

There are little data on patient factors that impact diagnosis rates of celiac disease. This study aims to evaluate the association between patient socioeconomic status and the symptoms at diagnosis of celiac disease. A total of 872 patients with biopsy-proven celiac disease were categorized based on the presence or absence of (1) diarrhea and (2) any gastrointestinal symptoms at diagnosis. Univariate and multivariate analyses were used to assess the association between socioeconomic status and symptoms. Patients without diarrhea at presentation had a higher mean per capita income (US$34,469 versus US$32,237, p = 0.02), and patients without any gastrointestinal symptoms had a higher mean per capita income (US$36,738 versus US$31,758, p < 0.01) compared with patients having such symptoms. On multivariable analysis adjusting for sex, age, autoimmune or psychiatric comorbidities, and income, per capita income remained a significant predictor of diagnosis without gastrointestinal symptoms (odds ratio: 1.71, 95% confidence interval: 1.17-2.50, p < 0.01), and it showed a trend towards significance in diagnosis without diarrhea (odds ratio: 1.40, 95% confidence interval: 0.98-2.02, p = 0.06). Patients with nonclassical symptoms of celiac disease are less likely to be diagnosed if they are of lower socioeconomic status. Celiac disease may be under-recognized in this population due to socioeconomic factors that possibly include lower rates of health-seeking behavior and access to healthcare.

To investigate whether dual tissue-defined ischemic attacks, defined as multiple diffusion-weighted imaging lesions of different age and/or arterial territory (dual DWI), are an independent and stronger predictor of 90-day stroke than dual clinical TIAs (dual TIA). Consecutive patients with clinically defined TIA were enrolled and assessed clinically and by MRI within 3 days. The predictive ability of the ABCD clinical factors, dual TIA, and dual DWI was evaluated by means of multivariate logistic regression. Among 658 patients who were included in the study and completed 90 days of follow-up, a total of 70 patients (10.6%) experienced subsequent stroke by 90 days. Multivariate logistic regression indicated that dual DWI was an independent predictor for subsequent stroke (odds ratio 4.64, 95% confidence interval 2.15-10.01), while dual TIA was not (odds ratio 1.18, 95% confidence interval 0.69-2.01). C statistics was higher when the item of dual TIA in ABCD3-I score was replaced by dual DWI (0.759 vs 0.729, p = 0.035). The net reclassification value for 90-day stroke risk was also improved (continuous net reclassification improvement 0.301, p = 0.017). Dual DWI independently predicted future stroke in patients with TIA. A new ABCD3-I score with dual DWI instead of dual clinical TIA may improve risk stratification for early stroke risk after TIA. © 2015 American Academy of Neurology.

To investigate the significance of preoperative Glasgow prognostic score (GPS) for postoperative prognostication of patients with colorectal cancer. Recent studies have revealed that the GPS, an inflammation-based prognostic score that includes only C-reactive protein (CRP) and albumin, is a useful tool for predicting postoperative outcome in cancer patients. However, few studies have investigated the GPS in the field of colorectal surgery. The GPS was calculated on the basis of admission data as follows: patients with an elevated level of both CRP (>10 mg/L) and hypoalbuminemia (Alb <35 g/L) were allocated a score of 2, and patients showing 1 or none of these blood chemistry abnormalities were allocated a score of 1 or 0, respectively. Prognostic significance was analyzed by univariate and multivariate analyses. A total of 315 patients were evaluated. Kaplan-Meier analysis and log-rank test revealed that a higher GPS predicted a higher risk of postoperative mortality (P < 0.01). Univariate analyses revealed that postoperative TNM was the most sensitive predictor of postoperative mortality (odds ratio, 0.148; 95% confidence interval, 0.072-0.304; P < 0.0001). Multivariate analyses using factors such as age, sex, tumor site, serum carcinoembryonic antigen, CA19-9, CA72-4, CRP, albumin, and GPS revealed that GPS (odds ratio, 0.165; 95% confidence interval, 0.037-0.732; P = 0.0177) was associated with postoperative mortality. Preoperative GPS is considered to be a useful predictor of postoperative mortality in patients with colorectal cancer.

Purpose We aimed to retrospectively evaluate the risk factors for hypertensive attack during adrenalectomy in patients with pheochromocytoma. Despite the development of newer surgical and anesthetic techniques for the management of pheochromocytoma, intraoperative hypertensive attack continues to present a challenge. Materials and Methods Data from 53 patients diagnosed with pheochromocytoma at Kyungpook National Uriversity Medical Center between January 2000 and June 2012 were retrospectively analyzed. The subjects were divided into 2 groups depending on the presence or absence of hypertensive attack at the time of surgery. Patient demographic characteristics and preoperative evaluations were assessed for their prognostic relevance with respect to hypertensive attack. A univariate analysis was conducted, and a multivariate logistic regression analysis was also performed. Results In the univariate analysis, systolic blood pressure at presentation, preoperative hormonal status (including epinephrine, norepinephrine, vanillylmandelic acid, and metanephrine levels in a 24-hour urine sample), tumor size, and postoperative systolic blood pressure were significantly associated with the development of hypertensive attack. In the multivariate analysis, preoperative epinephrine level and tumor size were independent factors that predicted hypertensive attack. The highest odds ratio for tumor size (2.169) was obtained at a cutoff value of 4.25 cm and the highest odds ratio for preoperative epinephrine (1.020) was obtained at a cutoff value of 166.3 µg/d. Conclusions In this study, a large tumor size and an elevated preoperative urinary epinephrine level were risk factors for intraoperative hypertensive attack in patients with pheochromocytoma.

The prevalence of schizophrenia and depression in the United States is far higher among Medicaid recipients than in the general population. Individuals suffering from mental illness, including schizophrenia and depression, also have higher rates of emergency department utilization, which is costly and may not generate the positive health outcomes desired. Disease management programs strive to help individuals suffering from chronic illnesses better manage their condition(s) and seek health care in the appropriate settings. The objective of this manuscript is to estimate a dose-response impact on hospital inpatient and emergency room utilizations for any reason by Medicaid recipients with depression or schizophrenia who received disease management contacts. Multivariate regression analysis of panel data taken from administrative claims was conducted to test the hypothesis that increased contacts lower the likelihood of all-cause inpatient admissions and emergency room visits. Subjects included 6,274 members of Illinois' non-institutionalized Medicaid-only aged, blind or disabled population diagnosed with depression or schizophrenia. The statistical measure is the odds ratio. The odds ratio association is between the monthly utilization indicators and the number of contacts (doses) a member had for each particular disease management intervention. Higher numbers of intervention contacts for Medicaid recipients diagnosed with depression or schizophrenia were associated with statistically significant reductions in all-cause inpatient admissions and emergency room utilizations. There is a high correlation between depression and schizophrenia disease management contacts and lowered all-cause hospital inpatient and emergency room utilizations.

To investigate the association between psychosocial work conditions and unemployment, and low leisure-time physical activity. The 2000 public health survey in Scania is a cross-sectional postal questionnaire study with a 59% participation rate. A total of 5,180 persons aged 18-64 years who belonged to the workforce and the unemployed were included in this study. Logistic regression models were used to investigate the associations between psychosocial factors at work and unemployment, and low leisure-time physical activity. Psychosocial conditions at work were defined according to the Karasek-Theorell demand-control/decision latitudes into relaxed, active, passive, and job strain categories. The multivariate analyses included age, country of birth, education, economic stress, and social participation. In total, 16.1% of men and 14.8% of women had low leisure-time physical activity. The job strain (high demands/low control) and unemployed categories had significantly higher odds ratios of low leisure-time physical activity among both men and women compared with the relaxed (low demands/high control) reference category. However, the significant differences between the job strain, the unemployed, and the relaxed categories disappeared in the multivariate models. Respondents with job strain or unemployment have significantly higher odds ratios of low leisure-time physical activity than the relaxed category. However, after adjustments for education in particular the differences disappear. Nevertheless, the results suggest that the association between psychosocial work conditions, which are often dependent on education, and leisure-time physical activity may be interesting to study in more detail.

A new breast cancer treatment, brachytherapy-based accelerated partial breast radiotherapy (RT), was adopted before long-term effectiveness evidence, potentially increasing morbidity and costs compared with whole breast RT. The aim of this study was to estimate complication rates and RT-specific and 1-year costs for a cohort of female Medicare beneficiaries diagnosed with breast cancer (N = 47 969). We analyzed 2005-2007 Medicare claims using multivariable logistic regression for complications and generalized linear models (log link, gamma distribution) for costs. Overall, 11% (n = 5296) underwent brachytherapy-based RT; 9.4% had complications. Odds of any complication were higher (odds ratio [OR]: 1.62; 95% confidence interval [CI]: 1.49-1.76) for brachytherapy versus whole breast RT, similarly to seroma (OR: 2.85; 95% CI: 1.97-4.13), wound complication/infection (OR: 1.72; 95% CI: 1.52-1.95), cellulitis (OR: 1.48; 95% CI: 1.27-1.73), and necrosis (OR: 2.07; 95% CI: 1.55-2.75). Mean RT-specific and 1-year total costs for whole breast RT were $6375, and $19 917, $4886, and $4803 lower than brachytherapy (P < .0001). Multivariable analyses indicated brachytherapy yielded 76% higher RT costs (risk ratio: 1.76; 95% CI: 1.74-1.78, P < .0001) compared with whole breast RT. Brachytherapy had higher complications and costs before long-term evidence proved its effectiveness. Policies should require treatment registries with reimbursement incentives to capture surveillance data for new technologies. PMID:29502466

Obesity and ectopic fat accumulation are important conditions of type 2 diabetes mellitus (T2DM). Our aim was to determine whether bioelectrical impedance body composition analysis combined with blood test results could estimate liver ectopic fat accumulation in patients with treatment-naïve T2DM. Subjects were 119 untreated T2DM patients. Computed tomography scans were performed to calculate the liver to spleen attenuation ratio (L/S ratio) as a measure of liver fat accumulation, with excess liver fat accumulation defined as an L/S ratio <1.0. Elementary body composition was measured by bioelectrical impedance analysis using InBody770. The Nagelkerke R 2 test showed that the muscle mass/fat mass ratio (muscle/fat ratio) was the most suitable variable among anthropometric factors and body component indexes for estimating liver fat accumulation. The muscle/fat ratio was significantly correlated with the L/S ratio (ρ = 0.4386, P < 0.0001). Multivariable logistic regression analysis showed that the muscle/fat ratio (odds ratio 0.40, 95% confidence interval 0.22-0.73, P < 0.01) and alanine aminotransferase (odds ratio 1.06, 95% confidence interval 1.02-1.10, P < 0.01) were independently and significantly associated with liver fat accumulation. In receiver operating characteristic curve analysis, the cutoff value of the muscle/fat ratio for excess liver fat accumulation was 2.34. In patients with treatment-naïve T2DM, the muscle/fat ratio and ALT are useful for estimating the presence of excess liver fat accumulation in daily clinical practice. Copyright © 2018.

Limited research shows an inconclusive association between soda intake and asthma, potentially attributable to certain preservatives in sodas. This cross-sectional study examined the association between regular (nondiet)-soda intake and current asthma among a nationally representative sample of high school students. Analysis was based on the 2009 national Youth Risk Behavior Survey and included 15,960 students (grades 9 through 12) with data for both regular-soda intake and current asthma status. The outcome measure was current asthma (ie, told by doctor/nurse that they had asthma and still have asthma). The main exposure variable was regular-soda intake (ie, drank a can/bottle/glass of soda during the 7 days before the survey). Multivariable logistic regression was used to estimate the adjusted odds ratios for regular-soda intake with current asthma after controlling for age, sex, race/ethnicity, weight status, and current cigarette use. Overall, 10.8% of students had current asthma. In addition, 9.7% of students who did not drink regular soda had current asthma, and 14.7% of students who drank regular soda three or more times per day had current asthma. Compared with those who did not drink regular soda, odds of having current asthma were higher among students who drank regular soda two times per day (adjusted odds ratio = 1.28; 95% CI 1.02 to 1.62) and three or more times per day (adjusted odds ratio = 1.64; 95% CI 1.25 to 2.16). The association between high regular-soda intake and current asthma suggests efforts to reduce regular-soda intake among youth might have benefits beyond improving diet quality. However, this association needs additional research, such as a longitudinal examination. PMID:23260727

2016-01-01

Objectives Qualitative studies have highlighted the possibility of job loss following occupational injuries for some workers, but prospective investigations are scant. We used a sample of nursing home workers from the Work, Family, and Health Network to prospectively investigate association between occupational injuries and job loss. Methods We merged data on 1331 workers assessed four times over an 18-month period with administrative data that include job loss from employers and publicly-available data on their workplaces. Workers self-reported occupational injuries in surveys. Multivariable logistic regression models estimated risk ratios for the impact of occupational injuries on overall job loss, whereas multinomial models were used to estimate odds ratio of voluntary and involuntary job loss. Use of marginal structural models allowed for adjustments of multilevel list of confounders that may be time-varying and/or on the causal pathway. Results By 12 months, 30.3% of workers experienced occupational injury, whereas 24.2% experienced job loss by 18 months. Comparing workers who reported occupational injuries to those reporting no injuries, risk ratio of overall job loss within subsequent 6 months was 1.31 (95% CI=0.93–1.86). Comparing the same groups, injured workers had higher odds of experiencing involuntary job loss (OR:2.19; 95% CI:1.27–3.77). Also, compared to uninjured workers, those injured more than once had higher odds of voluntary job loss (OR:1.95; 95% CI:1.03–3.67), while those injured once had higher odds of involuntary job loss (OR:2.19; 95% CI:1.18–4.05). Conclusions Despite regulatory protections, occupational injuries were associated with increased risk of voluntary and involuntary job loss for nursing home workers. PMID:26786757

Clostridium difficile infection is a healthcare-associated infection resulting in significant morbidity. Although immunosuppression is associated with Clostridium difficile infection acquisition and adverse outcomes, the epidemiology of Clostridium difficile infection in HIV-infected patients has been little studied in the era of antiretroviral therapy. This study identifies the risk factors for acquisition of Clostridium difficile infection in HIV-infected patients. A retrospective, propensity score-matched case-control study design was employed, with patients selected from our institution's outpatient HIV clinic. Clostridium difficile infection cases were defined as having positive stool testing plus an appropriate clinical presentation. The propensity score was generated via multiple logistic regression from year of HIV diagnosis, age at first contact, duration of follow-up, gender, and initial CD4 count. The 46 cases included were matched to a total of 180 controls. Prior antibiotic treatment was a significant predictor of Clostridium difficile infection (odds ratio: 13, 95% confidence interval: 3.49-48.8, p  < .001) as was number of hospital admissions in the preceding year (odds ratio: 4.02, confidence interval: 1.81-8.94, p  < .001). Having both proton pump inhibitor use and CD4 count <200 cells/µL significantly increased odds of Clostridium difficile infection in the multivariable model (odds ratio: 15.17, confidence interval: 1.31-175.9, p  = .021). As in the general population, frequent hospitalizations and exposure to antimicrobials are independent predictors of Clostridium difficile infection acquisition in patients with HIV. Additionally, low CD4 count and proton pump inhibitor use are new potentially modifiable variables that can be targeted for prevention of Clostridium difficile infection in future interventional studies.

The Wii Balance Board has received increasing attention as a balance measurement tool; however its ability to prospectively predict falls is unknown. This exploratory study investigated the use of the Wii Balance Board and other clinical-based measures for prospectively predicting falls among community-dwelling older adults. Seventy-three community-dwelling men and women, aged 60-85years were followed-up over a year for falls. Standing balance was indexed by sway velocities measured using the Wii Balance Board interfaced with a laptop. Clinical-based measures included Short Physical Performance Battery, gait speed and Timed-Up-and-Go test. Multivariable regression analyses were used to assess the ability of the Wii Balance Board measure to complement the TUG test in fall screening. Individually, the study found Wii Balance Board anteroposterior (odds ratio 1.98, 95% CI 1.16 to 3.40, P=0.01) and mediolateral (odds ratio 2.80, 95% CI 1.10 to 7.13, p=0.03) sway velocity measures predictive of prospective falls. However, when each velocity measure was adjusted with body mass index and Timed-Up-and-Go, only anteroposterior sway velocity was predictive of prospective falls (odds ratio 2.21, 95% CI 1.18 to 4.14). A faster anteroposterior velocity was associated with increased odds of falling. Area-under-the-curves for Wii Balance Board sway velocities were 0.67 and 0.71 for anteroposterior and mediolateral respectively. The Wii Balance Board-derived anteroposterior sway velocity measure could complement existing clinical-based measures in predicting future falls among community-dwelling older adults.

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.

An estimated 25-60% of adults with sickle cell disease (SCD) are unemployed. Factors contributing to the high unemployment rate in this population are not well studied. With the known risk of cognitive deficits associated with SCD, we tested the hypothesis that unemployment is related to decrements in intellectual functioning. We conducted a retrospective chart review of 50 adults with sickle cell anemia who completed cognitive testing, including the Wechsler Adult Intelligence Scale-IV, as part of standard care. Employment status was recorded at the time of testing. Medical variables examined as possible risk factors for unemployment included disease phenotype, cerebral infarction, and pain frequency. The mean age of the sample was 30.7 years (range = 19-59); 56% were women. Almost half of the cohort (44%) were unemployed. In a multivariate logistic regression model, lower IQ scores (odds ratio = 0.88; p = .002, 95% confidence interval, CI [0.82, 0.96]) and lower educational attainment (odds ratio = 0.13; p = .012, 95% CI [0.03, 0.65]) were associated with increasing odds of unemployment. The results suggest that cognitive impairment in adults with sickle cell anemia may contribute to the risk of unemployment. Helping these individuals access vocational rehabilitation services may be an important component of multidisciplinary care.

To determine whether subjective social standing in school predicts a change in body mass index (BMI) in adolescent girls during a 2-year period. Prospective cohort study. Self-report questionnaires from a community-based population of adolescent girls living across the United States from 1999 to 2001. Of 5723 girls aged 12 to 18 years participating in the Growing Up Today Study (GUTS), adequate information was available for 4446 (78%), who provided the analytic sample. Low subjective social status in the school. Change in BMI between 1999 and 2001 and multivariable odds ratio for a 2-U increase in BMI in girls with low subjective social status in the school compared with girls with higher subjective social status in the school. After adjusting for age, race/ethnicity, baseline BMI, diet, television viewing, depression, global and social self-esteem, menarche, height growth, mother's BMI, and pretax household income, adolescent girls who placed themselves on the low end of the school subjective social status scale had a 69% increased odds of having a 2-unit increase in BMI (odds ratio, 1.69; 95% confidence interval, 1.10-2.60) during the next 2 years compared with other girls. Higher subjective social standing in school may protect against gains in adiposity in adolescent girls.

The aim of this study is to identify image-based morphological parameters that correlate with human intracranial aneurysm (IA) rupture. For 45 patients with terminal or sidewall saccular IAs (25 unruptured, 20 ruptured), three-dimensional geometries were evaluated for a range of morphological parameters. In addition to five previously studied parameters (aspect ratio, aneurysm size, ellipticity index, nonsphericity index, and undulation index), we defined three novel parameters incorporating the parent vessel geometry (vessel angle, aneurysm [inclination] angle, and [aneurysm-to-vessel] size ratio) and explored their correlation with aneurysm rupture. Parameters were analyzed with a two-tailed independent Student's t test for significance; significant parameters (P < 0.05) were further examined by multivariate logistic regression analysis. Additionally, receiver operating characteristic analyses were performed on each parameter. Statistically significant differences were found between mean values in ruptured and unruptured groups for size ratio, undulation index, nonsphericity index, ellipticity index, aneurysm angle, and aspect ratio. Logistic regression analysis further revealed that size ratio (odds ratio, 1.41; 95% confidence interval, 1.03-1.92) and undulation index (odds ratio, 1.51; 95% confidence interval, 1.08-2.11) had the strongest independent correlation with ruptured IA. From the receiver operating characteristic analysis, size ratio and aneurysm angle had the highest area under the curve values of 0.83 and 0.85, respectively. Size ratio and aneurysm angle are promising new morphological metrics for IA rupture risk assessment. Because these parameters account for vessel geometry, they may bridge the gap between morphological studies and more qualitative location-based studies.

Studies showed that poor health and nutrition among school adolescents are major barriers to educational access and achievements in low-income countries. This school-based study was aimed to assess the association of school absenteeism and food insecurity among rural school adolescents from grades 5 to 8 in Jimma zone, Ethiopia. Regression analyses were used to see the strength of association between dependent and independent variables using odds ratio and 95% confidence intervals. Multivariable logistic regression analysis was used to identify the predictor of school absenteeism. Validated tools are used to collect household food insecurity data. Results showed that school absenteeism is significantly high among adolescents from food insecure households when compared to adolescents from food secure households ( P <.001). School absenteeism was negatively associated with male sex (adjusted odds ratio [AOR] = -0.91, 95% CI -1.85 to -0.03), household food security (adjusted odds ratio = -1.85, 95% CI -3.11 to -0.59), being an elder sibling (AOR = -0.37, 95% CI, -0.62 to -0.12), and mother involvement in decision making (AOR = -0.68, 95% CI, -1.33 to -0.03) while male-headed household was positively associated (AOR = 2.46, 95% CI, 1.37 to 4.56). Generally, this study showed that household food insecurity has significant contribution to school absenteeism among rural adolescents. Therefore, efforts should be made to improve household income earning capacity to reduce the prevalence of school absenteeism among rural school adolescents.

To evaluate effects of current and past sunlight exposure and iris color on early and late age-related macular degeneration (AMD). Of 3,701 individuals from the EUGENDA database, 752 (20.3%) showed early AMD, 1,179 (31.9%) late AMD, and 1,770 (47.8%) were controls. Information about current and past sunlight exposure, former occupation type, subdivided in indoor working and outdoor working, and iris color were obtained by standardized interviewer-assisted questionnaires. Associations between environmental factors adjusted for age, gender, and smoking and early and late AMD were performed by multivariate regression analysis. Current sunlight exposure showed no association with early AMD or late AMD, but past sunlight exposure (≥8 hours outside daily) was significantly associated with early AMD (odds ratio: 5.54, 95% confidence interval 1.25-24.58, P = 0.02) and late AMD (odds ratio: 2.77, 95% confidence interval 1.25-6.16, P = 0.01). Outside working was found to be associated with late AMD (odds ratio: 2.57, 95% confidence interval 1.89-3.48, P = 1.58 × 10). No association was observed between iris color and early or late AMD. Sunlight exposure during working life is an important risk factor for AMD, whereas sunlight exposure after retirement seems to have less influence on the disease development. Therefore, preventive measures, for example, wearing sunglasses to minimize sunlight exposure, should start early to prevent development of AMD later in life.

The aim of the present study was to investigate trajectories of suicide attempt risks before and after granting of disability pension in young people. The analytic sample consisted of all persons 16-30 years old and living in Sweden who were granted a disability pension in the years 1995-1997; 2000-2002 as well as 2005-2006 (n = 26,624). Crude risks and adjusted odds ratios for suicide attempt were computed for the 9-year window around the year of disability pension receipt by repeated-measures logistic regressions. The risk of suicide attempt was found to increase continuously up to the year preceding the granting of disability pension in young people, after which the risk declined. These trajectories were similar for women and men and for disability pension due to mental and somatic diagnoses. Still, the multivariate odds ratios for suicide attempts for women and for disability pension due to mental disorders were 2.5- and 3.8-fold increased compared with the odds ratios for men and disability pension due to somatic disorders, respectively. Trajectories of suicide attempts differed for young individuals granted a disability pension during 2005-2006 compared with those granted during 1995-1997 and 2000-2002. We found an increasing risk of suicide attempt up until the granting of a disability pension in young individuals, after which the risk decreased. It is of clinical importance to monitor suicide attempt risk among young people waiting for the granting of a disability pension.

Objective The primary aim of this study was to design prediction models based on a functional marker (preoperative gait-speed) to predict readiness for home discharge time of ≤ 90 minutes, and to identify those at risk for unplanned admissions, after elective ambulatory surgery. Design This prospective observational cohort study evaluated all patients scheduled for elective ambulatory surgery. Home discharge readiness and unplanned admissions were the primary outcomes. Independent variables included preoperative gait speed, heart rate, and total anesthesia time. The relationship between all predictors and each primary outcome was determined in separate multivariable logistic regression models. Results After adjustment for covariates, gait speed with adjusted odds ratio = 3.71 (95% CI: 1.21-11.26), p=0.02; was independently associated with early home discharge readiness ≤90 minutes. Importantly, gait speed dichotomized as greater or less than 1 m/s predicted unplanned admissions with odds ratio = 0.35 (95% CI: 0.16 to 0.76, p=0.008) for those with speeds ≥ 1 m/s in comparison to those with speed < 1 m/s. In a separate model, prior history of cardiac surgery with adjusted odds ratio =7.5 (95% CI: 2.34-24.41)(p=0.001) was independently associated with unplanned admissions after elective ambulatory surgery, when other covariates were held constant. Conclusions This study demonstrates use of novel prediction models based on gait speed testing to predict early home discharge and to identify those patients at risk for unplanned admissions, after elective ambulatory surgery.

The aim of this study was to investigate the relationship between menopause and self-reported sleep quality in Chinese women without vasomotor symptoms. Cross-sectional data were collected from a decoded database of the National Cheng Kung University Hospital. Menopause was defined as absence of menses for at least 12 months or a history of hysterectomy and oophorectomy. Self-reported sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). A higher global PSQI score indicates poorer self-reported sleep quality, and a global PSQI score greater than 5 differentiates poor sleepers from good sleepers. Of the 1,088 women recruited, 353 (32.4%) were in postmenopause status. Postmenopausal women had higher mean (SD) global PSQI scores (8.0 [3.3] vs. 6.1 [2.2], P < 0.001) and a greater prevalence of poor sleepers (73.1% vs. 60.8%, P < 0.001) compared with premenopausal women. Multivariate linear regression analysis showed that menopause (β = 1.532; 95% CI, 1.135 to 1.949; P < 0.001) and snoring (β = 0.764; 95% CI, 0.299 to 1.228; P = 0.001) were positively associated with global PSQI scores, whereas long sleep duration (β = -0.791; 95% CI, -1.113 to -0.468; P < 0.001) was negatively associated with global PSQI scores. Multivariate logistic regression analyses showed that menopause (odds ratio, 1.453; 95% CI, 1.030 to 2.051; P < 0.05), long sleep duration (odds ratio, 0.545; 95% CI, 0.418 to 0.710; P < 0.001), and snoring (odds ratio, 2.022; 95% CI, 1.312 to 3.116; P = 0.001) were independent predictors of poor sleepers. Postmenopausal women without vasomotor symptoms have significantly higher global PSQI scores and a higher risk of being poor sleepers than premenopausal women. In addition, menopause and snoring are associated with an increased risk of poor self-reported sleep quality independently of cardiometabolic factors and lifestyle, whereas long sleep duration is associated with a decreased risk of poor self-reported sleep quality.

Pediatric severe sepsis is a major cause of morbidity and mortality worldwide, and hematopoietic cell transplant patients represent a high-risk population. We assessed the epidemiology of severe sepsis in hematopoietic cell transplant patients, describing patient outcomes compared with children with no history of hematopoietic cell transplant. Secondary analysis of the Sepsis PRevalence, OUtcomes, and Therapies point prevalence study, comparing demographics, sepsis etiology, illness severity, organ dysfunction, and sepsis-related treatments in patients with and without hematopoietic cell transplant. The primary outcome was hospital mortality. Multivariable logistic regression models were used to determine adjusted differences in mortality. International; 128 PICUs in 26 countries. Pediatric patients with severe sepsis prospectively identified over a 1-year period. None. In patients with severe sepsis, 37/567 (6.5%) had a history of hematopoietic cell transplant. Compared with patients without hematopoietic cell transplant, hematopoietic cell transplant patients had significantly higher hospital mortality (68% vs 23%; p < 0.001). Hematopoietic cell transplant patients were more likely to have hospital acquired sepsis and had more preexisting renal and hepatic dysfunction than non-hematopoietic cell transplant patients with severe sepsis. History of hematopoietic cell transplant, renal replacement therapy, admission from inpatient floor, and number of organ dysfunctions at severe sepsis recognition were independently associated with hospital mortality in multivariable analysis; hematopoietic cell transplant conferred the highest odds of mortality (odds ratio, 4.00; 95% CI, 1.78-8.98). In secondary analysis of hematopoietic cell transplant patients compared with other immunocompromised patients with severe sepsis, history of hematopoietic cell transplant remained independently associated with hospital mortality (odds ratio, 3.03; 95% CI, 1.11-8.27). In an international study of pediatric severe sepsis, history of hematopoietic cell transplant is associated with a four-fold increased odds of hospital mortality after adjustment for potential measured confounders. Hematopoietic cell transplant patients more often originated from within the hospital compared to children with severe sepsis without hematopoietic cell transplant, possibly providing an earlier opportunity for sepsis recognition and intervention in this high-risk population.

Emergency department imaging: are weather and calendar factors associated with imaging volume?

To identify weather and calendar factors that would enable prediction of daily emergency department (ED) imaging volume to aid appropriate scheduling of imaging resources for efficient ED function. Daily ED triage and imaging volumes for radiography, computed tomography (CT), and ultrasound were obtained from hospital databases for the period between January 2011 and December 2013 at a large tertiary urban hospital with a Level II trauma centre. These data were tabulated alongside daily weather conditions (temperature, wind and precipitation), day of week, season, and holidays. Multivariate analysis was performed. Pearson correlations were used to measure the association between number of imaging studies performed and ED triage volume. For every additional 50 triaged patients, the odds of having high (imaging volume ≥90th percentile) radiography, CT, and ultrasound volume increased by 4.3 times (p<0.001), 1.5 times (p=0.02), and 1.4 times (p=0.02), respectively. Tuesday was an independent predictor of high radiography volume (odds ratio=2.8) and Monday was an independent predictor of high CT volume (odds ratio=3.0). Weekday status was an independent factor increasing the odds of a high US volume compared to Saturday (odds ratios ranging from 5.6-9.8). Weather factors and other calendar variables were not independent predictors of high imaging volume. Using Pearson correlations, ED triage volume correlated with number of radiographs, CT, and ultrasound examinations with r=0.73, 0.37, and 0.41, respectively (p<0.0001). As ED triage volume was found to be the only factor associated with imaging volume for all techniques, analysis of predictors of ED triage volumes at a particular healthcare facility would be useful to determine imaging needs. Although calendar and weather factors were found to be minor or non-significant independent predictors of ED imaging utilisation, these may be important in influencing the actual number of ED triages.

Crowdfunding for medical expenses is growing in popularity. Through several websites, patients create public campaign profiles to which donors can contribute. Research on medical crowdfunding is limited, and there have been no studies of crowdfunding in orthopedics. Active medical crowdfunding campaigns for orthopedic trauma, total joint arthroplasty, and spine surgery were queried from a crowdfunding website. The characteristics and outcomes of crowdfunding campaigns were abstracted and analyzed. For this study, 444 campaigns were analyzed, raising a total of $1,443,528. Among the campaigns that received a donation, mean amount raised was $4414 (SE, $611). Multivariate analysis showed that campaigns with unspecified location (odds ratio, 0.26; P=.0008 vs West) and those for total joint arthroplasty (odds ratio, 0.35; P=.0003 vs trauma) had significantly lower odds of receipt of any donation. Description length was associated with higher odds of donation receipt (odds ratio, 1.13 per +100 characters; P<.0001). Among campaigns that received any donation, those with Southern location (-65.5%, P<.0001), international location (-68.5%, P=.0028), and unspecified location (-63.5%, P=.0039) raised lower amounts compared with campaigns in the West. Goal amount was associated with higher amount raised (+3.2% per +$1000, P<.0001). Resources obtained through crowdfunding may be disproportionately available to patients with specific diagnoses, those from specific regions, those who are able to craft a lengthy descriptive narrative, and those with access to robust digital social networks. Clinicians are likely to see a greater proportion of patients turning to crowdfunding as it grows in popularity. Patients may ask physicians for information about crowdfunding or request testimonials to support campaigns. Surgeons should consider their response to such requests individually. These findings shed light on the dynamics of medical crowdfunding and support robust personal and professional deliberation. [Orthopedics. 2018; 41(1):e58-e63.]. Copyright 2017, SLACK Incorporated.

Although outcomes for patients with squamous cell carcinoma of the anus (SCCA) have improved, the gains in benefit may not be shared uniformly among patients of disparate socioeconomic status. In the current study, the authors investigated whether area-based median household income (MHI) is predictive of survival among patients with SCCA. Patients diagnosed with SCCA from 2004 through 2013 in the Surveillance, Epidemiology, and End Results registry were included. Socioeconomic status was defined by census-tract MHI level and divided into quintiles. Multivariable Cox proportional hazards models and logistic regression were used to study predictors of survival and radiotherapy receipt. A total of 9550 cases of SCCA were included. The median age of the patients was 58 years, 63% were female, 85% were white, and 38% were married. In multivariable analyses, patients living in areas with lower MHI were found to have worse overall survival and cancer-specific survival (CSS) compared with those in the highest income areas. Mortality hazard ratios for lowest to highest income were 1.32 (95% confidence interval [95% CI], 1.18-1.49), 1.31 (95% CI, 1.16-1.48), 1.19 (95% CI, 1.06-1.34), and 1.16 (95% CI, 1.03-1.30). The hazard ratios for CSS similarly ranged from 1.34 to 1.22 for lowest to highest income. Older age, black race, male sex, unmarried marital status, an earlier year of diagnosis, higher tumor grade, and later American Joint Committee on Cancer stage of disease also were associated with worse CSS. Income was not found to be associated with the odds of initiating radiotherapy in multivariable analysis (odds ratio of 0.87 for lowest to highest income level; 95% CI, 0.63-1.20). MHI appears to independently predict CSS and overall survival in patients with SCCA. Black race was found to remain a predictor of SCCA survival despite controlling for income. Further study is needed to understand the mechanisms by which socioeconomic inequalities affect cancer care and outcomes.

Microalbuminuria is a known marker of subclinical organ damage. Its prevalence is higher in patients with resistant hypertension than in subjects with blood pressure at goal. On the other hand, some patients with apparently well-controlled hypertension still have microalbuminuria. The current study aimed to determine the relationship between microalbuminuria and both office and 24-hour ambulatory blood pressure. A cohort of 356 patients (mean age 64 ± 11 years; 40.2% females) with resistant hypertension (blood pressure ≥ 140 and/or 90 mm Hg despite treatment with ≥ 3 drugs, diuretic included) were selected from Spanish hypertension units. Patients with estimated glomerular filtration rate <30 mL/min/1.73 m(2) were excluded. All patients underwent clinical and demographic evaluation, complete laboratory analyses, and good technical-quality 24-hour ambulatory blood pressure monitoring. Urinary albumin/creatinine ratio was averaged from 3 first-morning void urine samples. Microalbuminuria (urinary albumin/creatinine ratio ≥ 2.5 mg/mmol in males or ≥ 3.5 mg/mmol in females) was detected in 46.6%, and impaired renal function (estimated glomerular filtration rate <60 mL/min/1.73 m(2)) was detected in 26.8%. Bivariate analyses showed significant associations of microalbuminuria with older age, reduced estimated glomerular filtration rate, increased nighttime systolic blood pressure, and elevated daytime, nighttime, and 24-hour diastolic blood pressure. In a logistic regression analysis, after age and sex adjustment, elevated nighttime systolic blood pressure (multivariate odds ratio, 1.014 [95% CI, 1.001 to 1.026]; P=0.029) and reduced estimated glomerular filtration rate (multivariate odds ratio, 2.79 [95% CI, 1.57 to 4.96]; P=0.0005) were independently associated with the presence of microalbuminuria. We conclude that microalbuminuria is better associated with increased nighttime systolic blood pressure than with any other office and 24-hour ambulatory blood pressure monitoring parameters.

Haemodynamically stable patients admitted for coronary artery bypass grafting in acute myocardial infarction often undergo delayed surgery in order to avoid the risks of emergency surgery. However, initially stable patients undergoing delayed surgery may develop low cardiac output syndrome (LCOS) during the waiting period, which might be a major drawback of this strategy. We aim to define risk factors and clinical consequences of LCOS during the waiting period. A total of 530 consecutive patients with acute myocardial infarction (33% non-ST-segment elevation myocardial infarction and 67% ST-segment-elevation myocardial infarction) underwent isolated coronary artery bypass grafting between 2008 and 2013. Outcomes after either immediate (<48 h after onset of symptoms) or delayed (>48 h after onset of symptoms) therapy were compared. Predictors of preoperative development of LCOS were identified using multivariate regression analysis. Of the 327 patients undergoing delayed therapy, 39 (12%) developed preoperative LCOS, resulting in increased mortality compared with patients who remained stable (21 vs 7.6%, P < 0.001). Immediate therapy resulted in similar mortality compared with delayed therapy (6.4 vs 7.6%; P = 0.68) and better 7-year survival (70 vs 55%; P < 0.001). Predictors of developing LCOS were reduced left ventricular function (odds ratio 4.4), renal impairment (odds ratio 3.0), acute pulmonary infection (odds ratio 3.4) and the extent of troponin elevation at admission (odds ratio 1.01 per increase by 1 µg/l). In patients with acute myocardial infarction undergoing delayed coronary artery bypass grafting, preoperative LCOS is a relevant and dangerous condition that can be avoided by operating immediately or by carefully selecting patients to be delayed according to the risk parameters identified preoperatively. © The Author 2017.

The effect of an atherothrombotic aorta on the short- and long-term outcomes of total aortic arch replacement, including postoperative neurologic deficits, remains unknown. We evaluated this relationship and also elucidated the synergistic effect of multiple other risk factors, in addition to an atherothrombotic aorta, on the neurologic outcome. A group of 179 consecutive patients undergoing total aortic arch replacement were studied. An atherothrombotic aorta was present in 34 patients (19%), more than moderate leukoaraiosis in 71 (39.7%), and significant extracranial carotid artery stenosis in 27 (15.1%). In-hospital deaths occurred in 2 patients, 1 (2.9%) of 34 patients with and 1 (0.7%) of 145 patients without an atherothrombotic aorta (P = .26). Permanent neurologic deficits occurred in 4 (2.2%) and transient neurologic deficits in 17 (9.5%) patients. Multivariate analysis demonstrated that the risk factors for transient neurologic deficits were an atherothrombotic aorta (odds ratio, 4.4), extracranial carotid artery stenosis (odds ratio, 5.5), moderate/severe leukoaraiosis (odds ratio, 3.6), and cardiopulmonary bypass time (odds ratio, 1.02). To calculate the probability of transient neurologic deficits, the following equation was derived: probability of transient neurologic deficits = {1 + exp [7.276 - 1.489 (atherothrombotic aorta) - 1.285 (leukoaraiosis) - 1.701 (extracranial carotid artery stenosis) - 0.017 (cardiopulmonary bypass time)]}(-1). An exponential increase occurred in the probability of transient neurologic deficits with presence of an atherothrombotic aorta and other risk factors in relation to the cardiopulmonary bypass time. Survival at 3 years after surgery was significantly reduced in patients with vs without an atherothrombotic aorta (75.0% ± 8.8% vs 89.2% ± 3.1%, P = .01). Patients with an atherothrombotic aorta and associated preoperative comorbidities might be predisposed to adverse short- and long-term outcomes, including transient neurologic deficits.

To investigate the association between maternal socioeconomic status and the risk of encephalopathy in full-term newborns. Population-based case-control study. Washington State births from 1994 through 2002 recorded in the linked Washington State Birth Registry and Comprehensive Hospital Abstract Reporting System. Cases (n = 1060) were singleton full-term newborns with Comprehensive Hospital Abstract Reporting System International Classification of Diseases, Ninth Revision diagnoses of seizures, birth asphyxia, central nervous system dysfunction, or cerebral irritability. Control cases (n = 5330) were singleton full-term newborns selected from the same database. Main Exposures Socioeconomic status was defined by median income of the census tract of the mother's residence, number of years of maternal educational achievement, or maternal insurance status. Odds ratios estimating the risk of encephalopathy associated with disadvantaged socioeconomic status were calculated in 3 separate analyses using multivariate adjusted logistic regression. Newborns of mothers living in neighborhoods in which residents have a low median income were at increased risk of encephalopathy compared with newborns in neighborhoods in which residents have a median income more than 3 times the poverty level (adjusted odds ratio, 1.9; 95% confidence interval, 1.5-2.3). There was also a trend for increasing risk of encephalopathy associated with decreasing neighborhood income (P<.001). Newborns of mothers with less than 12 years of educational achievement had a higher risk of encephalopathy compared with newborns of mothers with more than 16 years of educational achievement (adjusted odds ratio, 1.7; 95% confidence interval, 1.3-2.3). Newborns of mothers receiving public insurance also had a higher risk of encephalopathy compared with newborns of mothers who have commercial insurance (adjusted odds ratio, 1.4; 95% confidence interval, 1.2-1.7). Disadvantaged socioeconomic status was independently associated with an increased risk of encephalopathy in full-term newborns. These findings suggest that a mother's socioeconomic status may influence the risk of encephalopathy for her full-term newborn.

To evaluate the association of serum levels of N(ε)- Carboxy methyl lysine (N(ε)-CML), an advanced glycation end product with topographic alterations in retinal pigment epithelium (RPE) in diabetic retinopathy on spectral domain optical coherence tomography (SD-OCT). Consecutive cases of type 2 diabetes mellitus with no retinopathy (n=20); non-proliferative diabetic retinopathy (n=20); proliferative diabetic retinopathy (n=20) and healthy controls (n=20) between the ages of 40 and 65years were included. RPE alterations were graded on segmentation map of SD-OCT: grade 0, No RPE alterations; grade 1, RPE alterations in up to two quadrants and grade 2, RPE alterations in more than two quadrants. Serum level of N(ε)-CML and glycated hemoglobin (HbA1c) was analyzed using the standard protocol. Statistical analysis was done. Significant increase in N(ε)-CML was observed with increased severity of diabetic retinopathy (F=34.1; p<0.0001). Fisher exact test revealed significant increase in grades of RPE alterations with increased severity of diabetic retinopathy (p<0.001). Univariate ordinal regression analysis was done to calculate the risk of progression in grades of RPE alteration with individual changes in variables like duration of diabetes (odds ratio=1.37; p=0.001), HbA1c (odds ratio=1.37; p=0.002) and Nε-CML (odds ratio=1.37; p<0.0001). Multivariate ordinal regression analysis for predicting progression in grades of RPE alteration revealed Nε-CML to be an independent predictor of increase in grades of RPE alteration (adjusted odds ratio=1.07; p<0.01) when duration of diabetes and HbA1c were held constant. Increase in serum levels of N(ε)- Carboxy methyl lysine is significantly associated with topographic alterations in RPE. Grades of RPE alteration increase significantly with increased severity of diabetic retinopathy. Copyright © 2016 Elsevier Inc. All rights reserved.

Cardiac arrest is a catastrophic event that may arise during the management of convulsive status epilepticus. We aimed to report the clinical characteristics, outcomes, and early predictors of convulsive status epilepticus-related cardiac arrest. Retrospective multicenter study. Seventeen university or university affiliated participating ICUs in France and Belgium. Consecutive patients admitted to the participating ICUs for management of successfully resuscitated out-of-hospital cardiac arrest complicating the initial management of convulsive status epilepticus between 2000 and 2015. Patients were compared with controls without cardiac arrest identified in a single-center registry of convulsive status epilepticus patients, regarding characteristics, management, and outcome. None. We included 49 cases with convulsive status epilepticus-cardiac arrest and 235 controls. In the cases, median time from medical team arrival to cardiac arrest was 25 minutes (interquartile range, 5-85 min). First recorded rhythm was asystole in 25 patients (51%) and pulseless electrical activity in 13 patients (27%). A significantly larger proportion of patients had a favorable 1-year outcome (Glasgow Outcome Scale score of 5) among controls (90/235; 38%) than among cases (10/49; 21%; p = 0.02). By multivariate analysis, independent predictors of cardiac arrest were pulse oximetry less than 97% on scene (odds ratio, 2.66; 95% CI, 1.03-7.26; p = 0.04), drug poisoning as the cause of convulsive status epilepticus (odds ratio, 4.13; 95% CI, 1.27-13.53; p = 0.02), and complications during early management (odds ratio, 11.98; 95% CI, 4.67-34.69; p < 0.0001). Having at least one comorbidity among cardiac, respiratory, and neurologic (other than epilepsy) conditions predicted absence of cardiac arrest (odds ratio, 0.28; 95% CI, 0.10-0.80; p = 0.02). In patients managed for convulsive status epilepticus, relative hypoxemia, on-scene management complications, and drug poisoning as the cause of convulsive status epilepticus were strong early predictors of cardiac arrest, suggesting areas for improvement.

The genetic architecture of coronary artery disease has not been fully elucidated, especially in Asian countries. Moyamoya disease is a progressive cerebrovascular disease that is reported to be complicated by coronary artery disease. Because most Japanese patients with moyamoya disease carry the p.R4810K variant of the ring finger 213 gene (RNF213), this may also be a risk factor for coronary artery disease; however, this possibility has never been tested. We genotyped the RNF213 p.R4810K variant in 956 coronary artery disease patients and 716 controls and tested the association between p.R4810K and coronary artery disease. We also validated the association in an independent population of 311 coronary artery disease patients and 494 controls. In the replication study, the p.R4810K genotypes were imputed from genome-wide genotyping data based on the 1000 Genomes Project. We used multivariate logistic regression analyses to adjust for well-known risk factors such as dyslipidemia and smoking habits. In the primary study population, the frequency of the minor variant allele was significantly higher in patients with coronary artery disease than in controls (2.04% vs. 0.98%), with an odds ratio of 2.11 (p = 0.017). Under a dominant model, after adjustment for risk factors, the association remained significant, with an odds ratio of 2.90 (95% confidence interval: 1.37-6.61; p = 0.005). In the replication study, the association was significant after adjustment for age and sex (odds ratio = 4.99; 95% confidence interval: 1.16-21.53; p = 0.031), although it did not reach statistical significance when further adjusted for risk factors (odds ratio = 3.82; 95% confidence interval: 0.87-16.77; p = 0.076). The RNF213 p.R4810K variant appears to be significantly associated with coronary artery disease in the Japanese population.

The purpose of this study was to estimate the general population incidence of late-life agoraphobia and to define its clinical characteristics and risk factors. A total of 1,968 persons ≥65 years old were randomly recruited from the electoral rolls of the district of Montpellier, France. Prevalent and incident agoraphobia diagnosed with a standardized psychiatric examination and validated by a clinical panel were assessed at baseline and over a 4-year follow-up. The 1-month baseline prevalence of agoraphobia was estimated to be 10.4%. Among persons with agoraphobia, 10.9% reported having their first episode at age 65 or above. During the 4-year follow-up, 11.2% of participants without agoraphobia at baseline had a first episode, resulting in an incidence rate of 32 per 1,000 person-years. These 132 incident late-onset cases were associated with higher incidence rates of anxiety disorders and suicidal ideation. Of the incident cases, only two were characterized by past or concurrent panic attacks, a rate that was not significantly different from that of the noncase group. The principal baseline risk factors for incident cases, derived from a multivariate model incorporating all significant risk factors, were younger age at onset (odds ratio=0.94, 95% CI=0.90-0.99), poorer visuospatial memory performance (odds ratio=1.60, 95% CI=1.02-2.49), severe depression (odds ratio=2.62, 95% CI=1.34-5.10), and trait anxiety (odds ratio=1.73, 95% CI=1.03-2.90). No significant association was found with cardiac pathologies. Agoraphobia has a high prevalence in the elderly, and unlike cases in younger populations, late-onset cases are not more common in women and are not associated with panic attacks, suggesting a late-life subtype. Severe depression, trait anxiety, and poor visuospatial memory are the principal risk factors for late-onset agoraphobia.

The incidence of epilepsy in Ethiopia is high compared with industrialised countries, but in most cases the cause of epilepsy is unknown. Childhood malnutrition remains widespread. We performed a case-control study to determine whether epilepsy is associated with poverty and markers of early under-nutrition. Patients with epilepsy (n=112), aged 18-45years, were recruited from epilepsy clinics in and around two towns in Ethiopia. Controls with a similar age and gender distribution (n=149) were recruited from patients and relatives attending general outpatient clinics. We administered a questionnaire to define the medical and social history of cases and controls, and then performed a series of anthropometric measurements. Unconditional logistic regression was used to estimate multivariate adjusted odds ratios. Multiple linear regression was used to estimate adjusted case-control differences for continuously distributed outcomes. Epilepsy was associated with illiteracy/low levels of education, odds ratio=3.0 (95% confidence interval: 1.7-5.6), subsistence farming, odds ratio=2.6 (1.2-5.6) and markers of poverty including poorer access to sanitation (p=0.009), greater overcrowding (p=0.008) and fewer possessions (p<0.001). Epilepsy was also associated with the father's death during childhood, odds ratio=2.2 (1.0-4.6). Body mass index was similar in cases and controls, but patients with epilepsy were shorter and lighter with reduced sitting height (p<0.001), bitrochanteric diameter (p=0.029) and hip size (p=0.003). Patients with epilepsy also had lower mid-upper arm circumference (p=0.011) and lean body mass (p=0.037). Epilepsy in Ethiopia is strongly associated with poor education and markers of poverty. Patients with epilepsy also had evidence of stunting and disproportionate skeletal growth, raising the possibility of a link between early under-nutrition and epilepsy.

The length of large vessel occlusion is considered a major factor for therapy in patients with ischemic stroke. We used 4D-CT angiography evaluation of middle cerebral artery occlusion in prediction of recanalization and favorable clinical outcome and after intravenous thrombolysis (IV-tPA). In 80 patients treated with IV-tPA for acute complete middle cerebral artery/M1 occlusion determined using CT angiography and temporal maximum intensity projection, calculated from 4D-CT angiography, the length of middle cerebral artery proximal stump, occlusion in M1 or M1 and M2 segment were measured. Univariate and multivariate analyses were performed to define independent predictors of successful recanalization after 24 hours and favorable outcome after 3 months. The length of occlusion was measureable in all patients using temporal maximum intensity projection. Recanalization thrombolysis in myocardial infarction 2 to 3 was achieved in 37 individuals (46%). The extension to M2 segment as a category (odds ratio, 4.58; 95% confidence interval, 1.39-15.05; P=0.012) and the length of M1 segment occlusion (odds ratio, 0.82; 95% confidence interval, 0.73-0.92; P=0.0007) with an optimal cutoff value of 12 mm (sensitivity 0.67; specificity 0.71) were significant independent predictors of recanalization. Favorable outcome (modified Rankin scale 0-2) was achieved in 25 patients (31%), baseline National Institutes of Health Stroke Scale (odds ratio, 0.82; 95% confidence interval, 0.72-0.93; P=0.003) and the length of occlusion M1 in segment (odds ratio, 0.79; 95% confidence interval, 0.69-0.91; P=0.0008) with an optimal cutoff value of 11 mm (sensitivity 0.74; specificity 0.76) were significant independent predictors of favorable outcome. The length of middle cerebral artery occlusion is an independent predictor of successful IV-tPA treatment. © 2014 American Heart Association, Inc.

We sought to assess the risk of acute kidney injury (AKI) and mortality associated with intensive systolic blood pressure reduction in acute intracerebral hemorrhage. Patients with acute intracerebral hemorrhage had spontaneous cause and symptom onset within 24 hours. We excluded patients with structural causes, coagulopathy, thrombocytopenia, and preexisting end-stage renal disease. We defined AKI using the Acute Kidney Injury Network criteria. Chronic kidney disease status was included in risk stratification and was defined by Kidney Disease Outcomes Quality Initiative staging. Maximum systolic blood pressure reduction was defined over a 12-hour period and dichotomized using receiver operating characteristic curve analysis. Descriptive statistics were done using independent sample t tests, χ 2 tests, and Mann-Whitney U tests, whereas multivariable logistic regression analysis was used to evaluate for predictors for AKI and mortality. A total of 448 patients with intracerebral hemorrhage met inclusion criteria. Maximum systolic blood pressure reduction was dichotomized to 90 mm Hg and found to increase the risk of AKI in patients with normal renal function (odds ratio, 2.1; 95% confidence interval, 1.19-3.62; P =0.010) and chronic kidney disease (odds ratio, 3.91; 95% confidence interval, 1.26-12.15; P =0.019). The risk of AKI was not significantly different in normal renal function versus chronic kidney disease groups when adjusted for demographics, presentation characteristics, and medications associated with AKI. AKI positively predicted mortality for patients with normal renal function (odds ratio, 2.41; 95% confidence interval, 1.11-5.22; P =0.026) but not for patients with chronic kidney disease (odds ratio, 3.13; 95% confidence interval, 0.65-15.01; P =0.154). These results indicate that intensive systolic blood pressure reduction with a threshold >90 mm Hg in patients with acute intracerebral hemorrhage may be an independent predictor for AKI. © 2018 The Authors.

2013-01-01

Background Infection in pregnancy may be involved in the aetiology of pre-eclampsia. However, a clear association between acute maternal infection and pre-eclampsia has not been established. We assessed whether acute urinary tract infection, respiratory tract infection, and antibiotic drug prescriptions in pregnancy (a likely proxy for maternal infection) are associated with an increased risk of pre-eclampsia. Methods and Findings We used a matched nested case-control design and data from the UK General Practice Research Database to examine the association between maternal infection and pre-eclampsia. Primiparous women aged at least 13 years and registered with a participating practice between January 1987 and October 2007 were eligible for inclusion. We selected all cases of pre-eclampsia and a random sample of primiparous women without pre-eclampsia (controls). Cases (n = 1533) were individually matched with up to ten controls (n = 14236) on practice and year of delivery. We calculated odds ratios and 95% confidence intervals for pre-eclampsia comparing women exposed and unexposed to infection using multivariable conditional logistic regression. After adjusting for maternal age, pre-gestational hypertension, diabetes, renal disease and multifetal gestation, the odds of pre-eclampsia were increased in women prescribed antibiotic drugs (adjusted odds ratio 1.28;1.14–1.44) and in women with urinary tract infection (adjusted odds ratio 1.22;1.03–1.45). We found no association with maternal respiratory tract infection (adjusted odds ratio 0.91;0.72–1.16). Further adjustment for maternal smoking and pre-pregnancy body mass index made no difference to our findings. Conclusions Women who acquire a urinary infection during pregnancy, but not those who have a respiratory infection, are at an increased risk of pre-eclampsia. Maternal antibiotic prescriptions are also associated with an increased risk. Further research is required to elucidate the underlying mechanism of this association and to determine whether, among women who acquire infections in pregnancy, prompt treatment or prophylaxis against infection might reduce the risk of pre-eclampsia.

We examined the association between perceived racial/ethnic harassment and tobacco use in 2129 African American college students in North Carolina. Age-adjusted and multivariate analyses evaluated the effect of harassment on daily and less-than-daily tobacco use. Harassed participants were twice as likely to use tobacco daily (odds ratio = 2.01; 95% confidence interval=1.94, 2.08) compared with those with no reported harassment experiences. Experiences of racial/ethnic harassment may contribute to tobacco use behaviors among some African American young adults. PMID:15671457

This study examined the early developmental context of children in immigrant families (CIF), measured by the frequency with which parents share books with their children. Trends in the frequency with which parents report book sharing, defined in this analysis as reading or sharing picture books with their young children, were analyzed across immigrant and nonimmigrant households by using data from the 2005, 2007, and 2009 California Health Interview Survey. Stepwise multivariate logistic regression assessed the likelihood that CIF shared books with parents daily. In this study, 57.5% of parents in immigrant families reported daily book sharing (DBS), compared with 75.8% of native-born parents. The lowest percentage of DBS was seen in Hispanic families with 2 foreign-born parents (47.1%). When controlling for independent variables, CIF with 2 foreign-born parents had the lowest odds of sharing books daily (odds ratio [OR]: 0.61; 95% confidence interval [CI]: 0.54-0.68). When stratified by race/ethnicity, separate multivariate logistic regressions revealed CIF status to be associated with lower odds of DBS for Asian (OR: 0.56; 95% CI: 0.38-0.81) and Hispanic CIF (OR: 0.49; 95% CI: 0.42-0.58). There is an association between the lower odds of DBS and parental immigrant status, especially for Hispanic and Asian children. This relationship holds after controlling for variables thought to explain differences in literacy-related practices, such as parental education and income. Because book sharing is central to children's development of early literacy and language skills, this disparity merits further exploration with the aim of informing future interventions.

Drug interactions have been identified as a risk factor for muscle-related side effects in statin users. The aim was to assess whether use of medications that inhibit cytochrome P450 (CYP450) isozymes, organic anion transporting polypeptide 1B1 (OATP1B1), or P-glycoprotein (P-gp) are associated with muscle-related symptoms among current and former statin users. Persons (n = 10,138) from the Understanding Statin Use in America and Gaps in Education (USAGE) internet survey were categorized about whether they ever reported new or worsening muscle pain while taking a statin (n = 2935) or ever stopped a statin because of muscle pain (n = 1516). Univariate and multivariate logistic regression models were used to assess associations between use of concomitant therapies that inhibit CYP450 isozymes, OATP1B1, P-gp, or a combination and muscle-related outcomes. In multivariate analyses, concomitant use of a CYP450 inhibitor was associated with increased odds for new or worse muscle pain (odds ratio [OR] = 1.42; P < .001) or ever having stopped a statin because of muscle pain (OR = 1.28; P = .037). Concomitant use of medication known to inhibit both OATP1B1 and P-gp was also associated with increased odds (OR = 1.80; P = .030) of ever having stopped a statin because of muscle pain. Concomitant use of medication(s) that inhibit statin metabolism was associated with increased odds of new or worse muscle pain while taking a statin and having previously stopped a statin because of muscle symptoms. These data emphasize the importance of enhancing the capabilities of clinicians and health systems for identifying and reducing statin drug interactions. Copyright © 2014 National Lipid Association.

Developing interventions to address racial/ethnic cancer pain disparities requires exploration of the role of socioeconomic status, health status, and pain severity from the time of diagnosis. To examine patterns of disparities in cancer pain by evaluating differences by race/ethnicity in the odds of reporting pain and in pain severity, controlling for key patient-level covariates. This study used data from a nationally representative cohort of colorectal and lung cancer patients. Multivariable logistic regression was conducted to examine the relationship between race/ethnicity and reporting pain. Multivariable linear regression was then conducted, among those who reported pain, to determine differences in pain severity by race/ethnicity. The cohort included 5761 individuals (14% black, 7% Hispanic/Latino, 6% Asian or Pacific Islander, and 3% multiracial), among whom 48% reported pain. The adjusted odds of reporting differed only for multiracial patients, who were more likely to report pain than whites (odds ratio: 1.54; P = 0.036). However, among those with pain, severity was higher for black patients (β = 6.6; P ≤ 0.001) and multiracial patients (β = 4.5; P = 0.036) relative to white patients. Lower educational attainment, depressed affect, and lower levels of wealth also were associated with higher pain severity. Although the odds of experiencing pain differed only for multiracial patients, among those reporting pain, both blacks and multiracial individuals reported higher pain severity than whites. Sociodemographic status, health status, and depression were associated with severity but did not explain the disparity. Interventions to address these disparities will need to focus on reported severity and patient-level factors. Published by Elsevier Inc.

Understanding multilevel predictors of colorectal cancer (CRC) screening test modality can help inform screening program design and implementation. We used North Carolina Medicare, Medicaid, and private, commercially available, health plan insurance claims data from 2003 to 2008 to ascertain CRC test modality among people who received CRC screening around their 50th birthday, when guidelines recommend that screening should commence for normal risk individuals. We ascertained receipt of colonoscopy, fecal occult blood test (FOBT) and fecal immunochemical test (FIT) from billing codes. Person-level and county-level contextual variables were included in multilevel random intercepts models to understand predictors of CRC test modality, stratified by insurance type. Of 12,570 publicly-insured persons turning 50 during the study period who received CRC testing, 57% received colonoscopy, whereas 43% received FOBT/FIT, with significant regional variation. In multivariable models, females with public insurance had lower odds of colonoscopy than males (odds ratio [OR] = 0.68; p < 0.05). Of 56,151 privately-insured persons turning 50 years old who received CRC testing, 42% received colonoscopy, whereas 58% received FOBT/FIT, with significant regional variation. In multivariable models, females with private insurance had lower odds of colonoscopy than males (OR = 0.43; p < 0.05). People living 10-15 miles away from endoscopy facilities also had lower odds of colonoscopy than those living within 5 miles (OR = 0.91; p < 0.05). Both colonoscopy and FOBT/FIT are widely used in North Carolina among insured persons newly age-eligible for screening. The high level of FOBT/FIT use among privately insured persons and women suggests that renewed emphasis on FOBT/FIT as a viable screening alternative to colonoscopy may be important.

To investigate alcohol drinking status and the association between drinking patterns and visual impairment in an adult population in northern China. Cluster sampling was used to select samples. The protocol consisted of an interview, pilot study, visual acuity (VA) testing and a clinical examination. Visual impairment was defined as presenting VA worse than 20/60 in any eye. Drinking patterns included drinking quantity (standard drinks per week) and frequency (drinking days in the past week). Information on alcohol consumption was obtained from 8445 subjects, 963 (11.4%) of whom reported consuming alcohol. In multivariate analysis, alcohol consumption was significantly associated with older age (p < 0.001), male sex (p < 0.001), and higher education level (p < 0.01). Heavy intake (>14 drinks/week) was associated with higher odds of visual impairment. However, moderate intake (>1-14 drinks/week) was significantly associated with lower odds (adjusted odds ratio, OR, 0.7, 95% confidence interval, CI, 0.5-1.0) of visual impairment (p = 0.03). Higher drinking frequency was significantly associated with higher odds of visual impairment. Multivariate analysis showed that older age, male sex, and higher education level were associated with visual impairment among current drinkers. Age- and sex-adjusted ORs for the association of cataract and alcohol intake showed that higher alcohol consumption was not significantly associated with an increased prevalence of cataract (OR 1.2, 95% CI 0.4-3.6), whereas light and moderate alcohol consumption appeared to reduce incidence of cataract. Drinking patterns were associated with visual impairment. Heavy intake had negative effects on distance vision; meanwhile, moderate intake had a positive effect on distance vision.

While DNR utilization is a complex subjective phenomenon, the effect of such a decision can collectively influence attitudes of care. The role of palliative care in advanced PD has been under appreciated. We reviewed the Healthcare Cost and Utilization Project's National Inpatient Sample (NIS) database from 2012 for all hospitalizations ⩾65years. We identified PD by using ICD-9-CM code 332.0 and DNR status with ICD code - V49.86 entered during the same admission as a secondary diagnosis. We estimated risk of mortality by the 3M™ All Patient Refined DRG (APR DRG) classification System and generated multivariate regression models to assess associations between DNR and PD after adjusting for confounders. Finally, we tested for interaction by risk of mortality. We analyzed 12,700,000 hospitalizations with age ⩾65years in 2012, of which 246625 (1.94%) pts had PD. Proportion of DNR utilization was higher among PD patients vs. those without, 20895 (8.47%) vs. 723090 (5.8%) (p<0.01). In multivariable regression analysis, PD patients were associated with higher odds of DNR utilization [Adjusted Odds ratio (aOR): 1.26, 95% CI: 1.21, 1.30, p<0.001]. Finally, the odds of DNR utilization increased significantly with APR-DRG stage [aOR: 1 vs. 1.61 (Stage 2) vs. 2.46 (Stage 3) vs. 3.61 (Stage 4); p<0.0001]. PD patients have higher odds of DNR utilization than the general population, which worsens with increasing objective risk of mortality. This is likely correlated with perception of end of life and importance of QOL with increasing severity of overall illness. Copyright © 2016 Elsevier Ltd. All rights reserved.

Women's empowerment and ideal family size: an examination of DHS empowerment measures in Sub-Saharan Africa.

Upadhyay, Ushma D; Karasek, Deborah

2012-06-01

The Demographic and Health Survey (DHS) program collects data on women's empowerment, but little is known about how these measures perform in Sub-Saharan African countries. It is important to understand whether women's empowerment is associated with their ideal number of children and ability to limit fertility to that ideal number in the Sub-Saharan African context. The analysis used couples data from DHS surveys in four Sub-Saharan African countries: Guinea, Mali, Namibia and Zambia. Women's empowerment was measured by participation in household decision making, attitudes toward wife beating and attitudes toward refusing sex with one's husband. Multivariable linear regression was used to model women's ideal number of children, and multivariable logistic regression was used to model women's odds of having more children than their ideal. In Guinea and Zambia, negative attitudes toward wife beating were associated with having a smaller ideal number of children (beta coefficients, -0.5 and -0.3, respectively). Greater household decision making was associated with a smaller ideal number of children only in Guinea (beta coefficient, -0.3). Additionally, household decision making and positive attitudes toward women's right to refuse sex were associated with elevated odds of having more children than desired in Namibia and Zambia, respectively (odds ratios, 2.3 and 1.4); negative attitudes toward wife beating were associated with reduced odds of the outcome in Mali (0.4). Women's empowerment--as assessed using currently available measures--is not consistently associated with a desire for smaller families or the ability to achieve desired fertility in these Sub-Saharan African countries. Further research is needed to determine what measures are most applicable for these contexts.

To determine the frequency of naevus-associated melanoma among superficial spreading and nodular subtypes; and to investigate associations between naevus-associated melanoma and other clinico-pathological characteristics. Cross-sectional study of all patients with nodular and superficial spreading melanomas diagnosed between 1994 and 2015 at the Victorian Melanoma Service, Melbourne. Clinical and pathological characteristics of naevus-associated and de novo melanomas were assessed in univariable and multivariable logistic regression analyses. Of 3678 primary melanomas, 1360 (37.0%) were histologically associated with a naevus and 2318 (63.0%) were de novo melanomas; 71 of 621 nodular (11.4%) and 1289 of 3057 superficial spreading melanomas (42.2%) were histologically associated with a naevus. In multivariable analyses, the odds of being associated with a naevus were higher for melanomas located on the trunk (v head and neck: adjusted odds ratio [OR], 2.27; 95% CI, 1.73-2.96; P < 0.001), while the odds were lower for thicker tumours (adjusted OR, 0.75 per millimetre increase in Breslow thickness; 95% CI, 0.69-0.81; P < 0.001), amelanotic/hypomelanotic melanomas (adjusted OR, 0.68; 95% CI, 0.48-0.97; P = 0.035), and older age (patients 70 years or older v patients under 30 at diagnosis: adjusted OR, 0.28; 95% CI, 0.20-0.40; P < 0.001). After adjusting for confounders, the odds of an associated naevus was three times as high for superficial spreading melanomas as for nodular melanomas (adjusted OR, 3.05; 95% CI, 2.24-4.17; P < 0.001). Melanomas are most likely to arise in the absence of a pre-existing naevus, particularly nodular melanomas. Public health campaigns should therefore emphasise the detection of suspicious de novo lesions, as well as of changing lesions.

We sought to determine risk factors for deep vein thrombosis and pulmonary embolism during pregnancy or post partum. We performed a population-based case-control study. All Olmsted County, Minnesota, residents with a first lifetime deep vein thrombosis or pulmonary embolism during pregnancy or post partum from 1966 to 1990 were identified (N = 90). Where possible, a resident without deep vein thrombosis or pulmonary embolism was matched to each patient by date of the first live birth after the patient's child. The medical records of all remaining patients and all control subjects were reviewed for >25 baseline characteristics, which were tested as risk factors for deep vein thrombosis or pulmonary embolism. In multivariate analysis smoking (odds ratio, 2.4) and prior superficial vein thrombosis (odds ratio, 9.4) were independent risk factors for deep vein thrombosis or pulmonary thrombosis during pregnancy or post partum. Venous thromboembolism prophylaxis may be warranted for pregnant women with prior superficial vein thrombosis. Smoking cessation should be recommended, especially during pregnancy and the postpartum period.

In September 2001, ethnoreligious rioting occurred in Jos, Nigeria. Using a multistage cluster sampling technique, 290 respondents were recruited in Jos 7 to 9 months after the riot. Data were collected regarding demographics, exposure to traumatic events, and psychological symptoms. Resting pulse and blood pressure were recorded. A total of 145 (52.5%) witnessed or were victims of personal attacks, 165 (59.6%) lost their possessions, 56 (20.7%) had their homes burned, 44 (16.2%) witnessed relatives' deaths, and 8 (2.9%) were robbed. A total of 252 (89.7%) of the respondents met reexperiencing criteria, 138 (49.1%) met avoidance criteria, and 236 (84.0%) met arousal criteria for posttraumatic stress disorder (PTSD). A total of 116 (41%, 95% confidence interval [CI] = 36% to 47%) met all three categories for PTSD. Only personal attacks (adjusted odds ratio = 2.8, 95% CI = 1.7 to 4.7) and a heart rate of 90 beats/min or more (adjusted odds ratio = 2.8, 95% CI = 1.4 to 5.8) were significantly related to PTSD in a multivariate model.

To determine the 12-month prevalence of hand dermatitis among massage therapists, to investigate a potential association between hand dermatitis and the use of aromatherapy products, and to study potential associations with other known risk factors for hand dermatitis. Mailed survey. Philadelphia, Pa. Members of a national massage therapy organization who live in the greater Philadelphia region. Self-reported and symptom-based prevalences of hand dermatitis. The number of respondents was 350 (57%). The 12-month prevalence of hand dermatitis in subjects was 15% by self-reported criteria and 23% by a symptom-based method. In multivariate analysis, statistically significant independent risk factors for self-reported hand dermatitis included use of aromatherapy products in massage oils, lotions, or creams (odds ratio, 3.27; 95% confidence interval, 1.53-7.02; P =.002) and history of atopic dermatitis (odds ratio, 8.06; 95% confidence interval, 3.39-19.17; P<.001). The prevalence of hand dermatitis in massage therapists is high. Significant independent risk factors include use of aromatherapy products in massage oils, creams, or lotions and history of atopic dermatitis.

No standard approach to obtaining informed consent for stroke thrombolysis with tPA (tissue-type plasminogen activator) currently exists. We aimed to assess current nationwide practice patterns of obtaining informed consent for tPA. An online survey was developed and distributed by e-mail to clinicians involved in acute stroke care. Multivariable logistic regression analyses were performed to determine independent factors contributing to always obtaining informed consent for tPA. Among 268 respondents, 36.7% reported always obtaining informed consent and 51.8% reported the informed consent process caused treatment delays. Being an emergency medicine physician (odds ratio, 5.8; 95% confidence interval, 2.9-11.5) and practicing at a nonacademic medical center (odds ratio, 2.1; 95% confidence interval, 1.0-4.3) were independently associated with always requiring informed consent. The most commonly cited cause of delay was waiting for a patient's family to reach consensus about treatment. Most clinicians always or often require informed consent for stroke thrombolysis. Future research should focus on standardizing content and delivery of tPA information to reduce delays. © 2018 American Heart Association, Inc.

Multiple sclerosis can affect pediatric patients. Our aim was to compare characteristics between pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanic Americans. This was a cross-sectional analysis of 363 Hispanic American multiple scleroses cases; demographic and clinical characteristics were analyzed. A total of 110 Hispanic patients presented with multiple sclerosis before age 18 and 253 as adult multiple sclerosis. The most common presenting symptoms for both was optic neuritis. Polyfocal symptoms, seizures, and cognitive symptoms at presentation were more prevalent in pediatric-onset multiple sclerosis (P ≤ .001). Transverse myelitis was more frequent in adult-onset multiple sclerosis (P ≤ .001). Using multivariable analysis, pediatric-onset multiple sclerosis (adjusted odds ratio, 0.3OR 95% confidence interval 0.16-0.71, P = .004) and being US born (adjusted odds ratio, 0.553, 95% confidence interval 0.3-1.03, P = .006) were less likely to have severe ambulatory disability. Results suggest that pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanics have differences that could be important for treatment and prognosis. © The Author(s) 2016.

Studies of adult patient populations suggest that organizational culture is associated with quality improvement (QI) implementation, as well as patient outcomes. However, very little research on organizational culture has been performed in neonatal patient populations. This combined cross-sectional survey and retrospective cohort study assessed employee perceptions of organizational culture and QI implementation within 18 Canadian neonatal intensive care units. The associations between these data and neonatal outcomes in extremely preterm infants (born at < 29 weeks' gestation) were then assessed using multivariable analyses. Perceptions of unit culture and QI implementation varied according to occupation and age. Higher hierarchical culture was associated with increased survival without major morbidities (odds ratio, 1.04; 95% confidence interval, 1.01-1.06), as were higher QI implementation scores (odds ratio range, 1.20-1.36 by culture type). Our data suggest that organizational culture, particularly hierarchical culture, and level of QI implementation may play a role in neonatal outcomes.

To determine referral patterns from pediatric primary care to subspecialists for overweight/obesity and related comorbidities. We used the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey to identify overweight/obesity and 5 related comorbidities in primary care visits between 2005 and 2009 by children 6 to 18 years. The primary outcome was whether the visit ended in referral. We used multivariable analysis to examine factors associated with referral. We identified 34,225 database visits. A total of 17.1% were with overweight (body mass index=85th to 94th percentile) or obese (body mass index≥95th percentile) patients. A total of 7.1% of primary care visits with overweight/obese children ended in referral. Referral was more likely when obesity was the reason for visit (odds ratio=2.83; 95% confidence interval=1.61-4.97) but was not associated with presence of a comorbidity (odds ratio=1.35; 95% confidence interval=0.75-2.44). Most overweight or obese children are not referred, regardless of comorbidity status. One reason may be low levels of appropriate diagnosis.

Objective To evaluate the effect of preoperative anaemia and blood transfusion on 30-day postoperative morbidity and mortality in patients undergoing gynecological surgery. Study Design Data were analyzed from 12,836 women undergoing operation in the American College of Surgeons National Surgical Quality Improvement Program. Outcomes measured were; 30-day postoperative mortality, composite and specific morbidities (cardiac, respiratory, central nervous system, renal, wound, sepsis, venous thrombosis, or major bleeding). Multivariate logistic regression models were performed using adjusted odds ratios (ORadj) to assess the independent effects of preoperative anaemia (hematocrit <36.0%) on outcomes, effect estimates were performed before and after adjustment for perioperative transfusion requirement. Results The prevalence of preoperative anaemia was 23.9% (95%CI: 23.2–24.7). Adjusted for confounders by multivariate logistic regression; preoperative anaemia was independently and significantly associated with increased odds of 30-day mortality (OR: 2.40, 95%CI: 1.06–5.44) and composite morbidity (OR: 1.80, 95%CI: 1.45–2.24). This was reflected by significantly higher adjusted odds of almost all specific morbidities including; respiratory, central nervous system, renal, wound, sepsis, and venous thrombosis. Blood Transfusion increased the effect of preoperative anaemia on outcomes (61% of the effect on mortality and 16% of the composite morbidity). Conclusions Preoperative anaemia is associated with adverse post-operative outcomes in women undergoing gynecological surgery. This risk associated with preoperative anaemia did not appear to be corrected by use of perioperative transfusion. PMID:26147954

Stethoscopes are contaminated with bacteria, but predictors of stethoscope disinfection frequency are unknown. We sought to describe health care provider stethoscope disinfection attitudes and practices and determine predictors of frequent disinfection. We used an anonymous online survey of nurses, nurse practitioners, and physicians at a pediatric hospital. We assessed frequency and methods of disinfection, perceptions of contamination, and barriers to disinfection. Multivariate logistic regression models were used to identify independent predictors of disinfecting after every use. One thousand four hundred one respondents completed the survey: 76% believed that infection transmission occurs via stethoscopes, but only 24% reported disinfecting after every use. In multivariate analyses, belief that infection transmission occurs via stethoscopes significantly increased the odds of disinfection after every use (odds ratio [OR], 2.06 [95% confidence interval (CI): 1.38-3.06]). The odds of disinfection after every use were significantly decreased in those who perceived the following barriers: lack of time (OR, 0.31 [95% CI: 0.18-0.54]), lack of access to disinfection material (OR, 0.41 [95% CI: 0.29-0.57]), or lack of visual reminders to disinfect (OR, 0.22 [95% CI: 0.14-0.34]). Only a minority of pediatric health care providers reported disinfecting their stethoscopes after every use. Increasing access to disinfection materials and visual reminders in health care facilities may improve stethoscope disinfection practices.

Abstract: Food insecurity is associated with poor virologic outcomes, but this has not been studied during pregnancy and breastfeeding. We assessed sustained viral suppression from 8 weeks on antiretroviral therapy to 48 weeks postpartum among 171 pregnant and breastfeeding Ugandan women; 74.9% experienced food insufficiency. In multivariable analysis, food insufficiency [adjusted odds ratio (aOR) 0.38, 95% confidence interval (CI): 0.16 to 0.91], higher pretreatment HIV-1 RNA (aOR 0.55 per 10-fold increase, 95% CI: 0.37 to 0.82), and lopinavir/ritonavir versus efavirenz (aOR 0.49, 95% CI: 0.24 to 0.96) were associated with lower odds of sustained viral suppression. Interventions to address food security may improve virologic outcomes among HIV-infected women. PMID:26397935

Frailty is a clinical state of increased vulnerability resulting from aging-associated decline in physiologic reserve. Hip fractures are serious fall injuries that affect our aging population. We retrospectively sought to study the effect of frailty on postoperative outcomes after Total Hip Arthroplasty (THA) and Hemiarthroplasty (HA) for femoral neck fracture in a national data set. National Surgical Quality Improvement Project dataset (NSQIP) was queried to identify THA and HA for a primary diagnosis femoral neck fracture using ICD-9 codes. Frailty was assessed using the modified frailty index (mFI) derived from the Canadian Study of Health and Aging. The primary outcome was 30-day mortality and secondary outcomes were 30-day morbidity and failure to rescue (FTR). We used multivariate logistic regression to estimate odds ratio for outcomes while controlling for confounders. Of 3121 patients, mean age of patients was 77.34 ± 9.8 years. The overall 30-day mortality was 6.4% (3.2%-THA and 7.2%-HA). One or more severe complications (Clavien-Dindo class-IV) occurred in 7.1% patients (6.7%-THA vs.7.2%-HA). Adjusted odds ratios (ORs) for mortality in the group with the higher than median frailty score were 2 (95%CI, 1.4-3.7) after HA and 3.9 (95%CI, 1.3-11.1) after THA. Similarly, in separate multivariate analysis for Clavien-Dindo Class-IV complications and failure to rescue 1.6 times (CI95% 1.15-2.25) and 2.1 times (CI95% 1.12-3.93) higher odds were noted in above median frailty group. mFI is an independent predictor of mortality among patients undergoing HA and THA for femoral neck fracture beyond traditional risk factors such as age, ASA class, and other comorbidities.

Background Exercise is known to reduce disability and improve quality of life in people with Parkinson disease (PD). Although barriers to exercise have been studied in older adults, barriers in people with chronic progressive neurological diseases, such as PD, are not well defined. Objective The purpose of this study was to identify perceived barriers to exercise in people with PD. Design The study had a cross-sectional design. Methods People who had PD, dwelled in the community, and were at stage 2.4 on the Hoehn and Yahr scale participated in this cross-sectional study (N=260; mean age=67.7 years). Participants were divided into an exercise group (n=164) and a nonexercise group (n=96). Participants self-administered the barriers subscale of the Physical Fitness and Exercise Activity Levels of Older Adults Scale, endorsing or denying specific barriers to exercise participation. Multivariate logistic regression analysis was used to examine the contribution of each barrier to exercise behavior, and odds ratios were reported. Results Three barriers were retained in the multivariate regression model. The nonexercise group had significantly greater odds of endorsing low outcome expectation (ie, the participants did not expect to derive benefit from exercise) (odds ratio [OR]=3.93, 95% confidence interval [CI]=2.08–7.42), lack of time (OR=3.36, 95% CI=1.55–7.29), and fear of falling (OR=2.35, 95% CI=1.17–4.71) than the exercise group. Limitations The cross-sectional nature of this study limited the ability to make causal inferences. Conclusions Low outcome expectation from exercise, lack of time to exercise, and fear of falling appear to be important perceived barriers to engaging in exercise in people who have PD, are ambulatory, and dwell in the community. These may be important issues for physical therapists to target in people who have PD and do not exercise regularly. The efficacy of intervention strategies to facilitate exercise adherence in people with PD requires further investigation. PMID:23288910

The risk of advanced fibrosis in first-degree relatives of patients with nonalcoholic fatty liver disease and cirrhosis (NAFLD-cirrhosis) is unknown and needs to be systematically quantified. We aimed to prospectively assess the risk of advanced fibrosis in first-degree relatives of probands with NAFLD-cirrhosis. This is a cross-sectional analysis of a prospective cohort of 26 probands with NAFLD-cirrhosis and 39 first-degree relatives. The control population included 69 community-dwelling twin, sib-sib, or parent-offspring pairs (n = 138), comprising 69 individuals randomly ascertained to be without evidence of NAFLD and 69 of their first-degree relatives. The primary outcome was presence of advanced fibrosis (stage 3 or 4 fibrosis). NAFLD was assessed clinically and quantified by MRI proton density fat fraction (MRI-PDFF). Advanced fibrosis was diagnosed by liver stiffness greater than 3.63 kPa using magnetic resonance elastography (MRE). The prevalence of advanced fibrosis in first-degree relatives of probands with NAFLD-cirrhosis was significantly higher than that in the control population (17.9% vs. 1.4%, P = 0.0032). Compared with controls, the odds of advanced fibrosis among the first-degree relatives of probands with NAFLD-cirrhosis were odds ratio 14.9 (95% CI, 1.8-126.0, P = 0.0133). Even after multivariable adjustment by age, sex, Hispanic ethnicity, BMI, and diabetes status, the risk of advanced fibrosis remained both statistically and clinically significant (multivariable-adjusted odds ratio 12.5; 95% CI, 1.1-146.1, P = 0.0438). Using a well-phenotyped familial cohort, we demonstrated that first-degree relatives of probands with NAFLD-cirrhosis have a 12 times higher risk of advanced fibrosis. Advanced fibrosis screening may be considered in first-degree relatives of NAFLD-cirrhosis patients. 140084.

BACKGROUND. The risk of advanced fibrosis in first-degree relatives of patients with nonalcoholic fatty liver disease and cirrhosis (NAFLD-cirrhosis) is unknown and needs to be systematically quantified. We aimed to prospectively assess the risk of advanced fibrosis in first-degree relatives of probands with NAFLD-cirrhosis. METHODS. This is a cross-sectional analysis of a prospective cohort of 26 probands with NAFLD-cirrhosis and 39 first-degree relatives. The control population included 69 community-dwelling twin, sib-sib, or parent-offspring pairs (n = 138), comprising 69 individuals randomly ascertained to be without evidence of NAFLD and 69 of their first-degree relatives. The primary outcome was presence of advanced fibrosis (stage 3 or 4 fibrosis). NAFLD was assessed clinically and quantified by MRI proton density fat fraction (MRI-PDFF). Advanced fibrosis was diagnosed by liver stiffness greater than 3.63 kPa using magnetic resonance elastography (MRE). RESULTS. The prevalence of advanced fibrosis in first-degree relatives of probands with NAFLD-cirrhosis was significantly higher than that in the control population (17.9% vs. 1.4%, P = 0.0032). Compared with controls, the odds of advanced fibrosis among the first-degree relatives of probands with NAFLD-cirrhosis were odds ratio 14.9 (95% CI, 1.8–126.0, P = 0.0133). Even after multivariable adjustment by age, sex, Hispanic ethnicity, BMI, and diabetes status, the risk of advanced fibrosis remained both statistically and clinically significant (multivariable-adjusted odds ratio 12.5; 95% CI, 1.1–146.1, P = 0.0438). CONCLUSION. Using a well-phenotyped familial cohort, we demonstrated that first-degree relatives of probands with NAFLD-cirrhosis have a 12 times higher risk of advanced fibrosis. Advanced fibrosis screening may be considered in first-degree relatives of NAFLD-cirrhosis patients. TRIAL REGISTRATION. UCSD IRB: 140084. FUNDING.

To characterize utilization of office-based optometry services by immigration status using a nationally representative database. The 2007 to 2011 Medical Expenditure Panel Survey is used to examine adults aged 18 years and older. Respondents were classified as US natives, naturalized citizens, and noncitizens. Multivariate logistic regression analysis examined the relationship of having visited an office-based optometrist within the past 12 months by immigrant status, adjusting for age, sex, education, race/ethnicity, marital status, self-reported vision difficulty, use of corrective lenses, poverty status, insurance, language barrier and usual source of care. Oaxaca-Blinder decomposition identified factors that perpetuate or ameliorate disparities in utilization across immigrant groups. The proportion of US natives who had visited an optometrist within the past year was 7.2%, almost three times higher than that for noncitizens (2.5%). Among respondents who reported vision difficulties, only 47.9% of noncitizens used corrective lenses compared with 71.0% of naturalized citizens and 71.6% of US natives. Adjusting for confounding factors, multivariate logistic regression showed that naturalized citizens and noncitizen residents had significantly lower odds than US natives of receiving optometry services (naturalized citizen adjusted odds ratio, 0.77; 95% confidence interval, 0.66 to 0.89; noncitizen adjusted odds ratio, 0.44; 95% confidence interval, 0.36 to 0.53). Decomposition analysis suggested that 17% of the disparity in utilization between noncitizens and US natives resulted from barriers to care such as language barriers, poverty, lack of insurance, and not having a usual source of health care. Prior literature suggests that immigrants have significantly poorer clinical vision outcomes than US natives. Our findings suggest that this disparity in clinical vision outcomes may result from underutilization of optometry services by immigrants compared with US natives. Immigrant patients may need targeted interventions that reduce barriers to care and change their perceptions so that regular eye care services are viewed as necessary and preventative.

Although many factors influence the management of carotid artery stenosis, it is not well understood whether a preference toward procedural management exists when procedural volume and physician compensation are linked in the fee-for-service environment. To explore evidence for provider-induced demand in the management of carotid artery stenosis. The Department of Defense Military Health System Data Repository was queried for individuals diagnosed with carotid artery stenosis between October 1, 2006, and September 30, 2010. A hierarchical multivariable model evaluated the association of the treatment system (fee-for-service physicians in the private sector vs salary-based military physicians) with the odds of procedural intervention (carotid endarterectomy or carotid artery stenting) compared with medical management. Subanalysis was performed by symptom status at the time of presentation. The association of treatment system and of management strategy with clinical outcomes, including stroke and death, was also evaluated. Data analysis was conducted from August 15, 2015, to August 2, 2016. The odds of procedural intervention based on treatment system was the primary outcome used to indicate the presence and effect of provider-induced demand. Of 10 579 individuals with a diagnosis of carotid artery stenosis (4615 women and 5964 men; mean [SD] age, 65.6 [11.4] years), 1307 (12.4%) underwent at least 1 procedure. After adjusting for demographic and clinical factors, the odds of undergoing procedural management were significantly higher for patients in the fee-for-service system compared with those in the salary-based setting (odds ratio, 1.629; 95% CI, 1.285-2.063; P < .001). This finding remained true when patients were stratified by symptom status at presentation (symptomatic: odds ratio, 2.074; 95% CI, 1.302-3.303; P = .002; and asymptomatic: odds ratio, 1.534; 95% CI, 1.186-1.984; P = .001). Individuals treated in a fee-for-service system were significantly more likely to undergo procedural management for carotid stenosis compared with those in the salary-based setting. These findings remained consistent for individuals with and without symptomatic disease.

To determine whether an impedance threshold device, designed to enhance circulation, would increase acute resuscitation rates for patients in cardiac arrest receiving conventional manual cardiopulmonary resuscitation. Prospective, randomized, double-blind, intention-to-treat. Out-of-hospital trial conducted in the Milwaukee, WI, emergency medical services system. Adults in cardiac arrest of presumed cardiac etiology. On arrival of advanced life support, patients were treated with standard cardiopulmonary resuscitation combined with either an active or a sham impedance threshold device. We measured safety and efficacy of the impedance threshold device; the primary end point was intensive care unit admission. Statistical analyses performed included the chi-square test and multivariate regression analysis. One hundred sixteen patients were treated with a sham impedance threshold device, and 114 patients were treated with an active impedance threshold device. Overall intensive care unit admission rates were 17% with the sham device vs. 25% in the active impedance threshold device (p = .13; odds ratio, 1.64; 95% confidence interval, 0.87, 3.10). Patients in the subgroup presenting with pulseless electrical activity had intensive care unit admission and 24-hr survival rates of 20% and 12% in sham (n = 25) vs. 52% and 30% in active impedance threshold device groups (n = 27) (p = .018, odds ratio, 4.31; 95% confidence interval, 1.28, 14.5, and p = .12, odds ratio, 3.09; 95% confidence interval, 0.74, 13.0, respectively). A post hoc analysis of patients with pulseless electrical activity at any time during the cardiac arrest revealed that intensive care unit and 24-hr survival rates were 20% and 11% in the sham (n = 56) vs. 41% and 27% in the active impedance threshold device groups (n = 49) (p = .018, odds ratio, 2.82; 95% confidence interval, 1.19, 6.67, and p = .037, odds ratio, 3.01; 95% confidence interval, 1.07, 8.96, respectively). There were no statistically significant differences in outcomes for patients presenting in ventricular fibrillation and asystole. Adverse event and complication rates were also similar. During this first clinical trial of the impedance threshold device during standard cardiopulmonary resuscitation, use of the new device more than doubled short-term survival rates in patients presenting with pulseless electrical activity. A larger clinical trial is underway to determine the potential longer term benefits of the impedance threshold device in cardiac arrest.

Methylenetetrahydrofolate reductase (MTHFR) and thymidylate synthase (TS) play key roles in intracellular folate metabolism. Polymorphisms in these enzymes have been shown to modify toxicity of methotrexate (MTX) after hematopoietic cell transplantation. In this study, we evaluated the risk of acute graft-versus-host disease (GVHD) associated with genetic variation in recipient and donor MTHFR and TS genotypes to assess whether genotype alters the efficacy of MTX in acute GVHD prophylaxis. Data on the transplantation course were abstracted from medical records for 304 adults who received allogeneic hematopoietic cell transplants. MTHFR (C677T and A1298C) and TS (enhancer-region 28-base pair repeat, TSER, and 1494del6) genotypes were determined using polymerase chain reaction/restriction fragment length polymorphism and TaqMan assays. Multivariable logistic regression was used to assess the associations between genotypes and risk of acute GVHD. Compared with recipients with the wild-type MTHFR 677CC genotype, those with the variant 677T allele showed a decreased risk of detectable acute GVHD (677CT: odds ratio, 0.8; 95% confidence interval, 0.4-1.6; 677TT: odds ratio, 0.4; 95% confidence interval, 0.2-0.8; P for trend = .01). The variant MTHFR 1298C allele in recipients was associated with an increased risk of acute GVHD compared with the wild-type MTHFR 1298AA genotype (1298AC: odds ratio, 2.0; 95% confidence interval, 1.1-3.9; 1298CC: odds ratio, 3.6; 95% confidence interval, 1.0-12.7; P for trend < .01). No association with risk of acute GVHD was observed for donor MTHFR genotypes or for recipient or donor TS genotypes, with the exception of an increase in acute GVHD among recipients whose donors had the TSER 3R/2R genotype (odds ratio, 3.0; 95% confidence interval, 1.3-7.2). These findings indicate that host, but not donor, MTHFR genotypes modify the risk of acute GVHD in recipients receiving MTX, in a manner consistent with our previously reported associations between MTHFR genotypes and MTX toxicity. A direct trade-off between drug toxicity and drug efficacy may play a role. Alternatively, the systemic folate environment, regulated by host tissues, might influence donor T-cell growth and activity.

Contemporary data on patients presenting with acute limb ischemia (ALI), who are selected for treatment with endovascular peripheral vascular interventions (PVI), are limited. Our study examined outcomes following endovascular PVI in patients with ALI by comparing with patients treated for chronic critical limb ischemia using a regional quality improvement registry. Of the 11 035 patients in the Vascular Study Group of New England PVI database (2010-2014), we identified 365 patients treated for lower extremity ALI who were 5:1 frequency matched (by procedure year and arterial segments treated) to 1808 patients treated for critical limb ischemia. ALI patients treated with PVI had high burden of atherosclerotic risk factors and were more likely to have had prior ipsilateral revascularizations. ALI patients were less likely to be treated with self-expanding stents and more likely to undergo thrombolysis than patients with critical limb ischemia. In multivariable analysis, ALI was associated with higher technical failure (odds ratio 1.7, 95% confidence interval, 1.1%-2.5%), increased rate of distal embolization (odds ratio 2.7, 95% confidence interval, 1.5%-4.9%), longer length of stay (means ratio 1.6, 95% confidence interval, 1.4%-1.8%), and higher in-hospital mortality (odds ratio 2.8, 95% confidence interval, 1.3%-5.9%). ALI was not associated with risk of major amputation or mortality at 1 year. In a multicenter cohort of patients treated with PVI, we found that ALI patients selected for treatment with endovascular techniques experienced greater short-term adverse events but similar long-term outcomes as their critical limb ischemia counterparts. Further studies are needed to refine the selection of ALI patients who are best served by PVI. © 2018 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

A retrospective study of surgically treated patients with acute traumatic central cord syndrome (ATCCS) from the National Trauma Data Bank Research Data Set. To determine the association of time to surgery, pre-existing comorbidities, and injury severity on mortality and adverse events in surgically treated patients with ATCCS. Although earlier surgery has been shown to be beneficial for other spinal cord injuries, the literature is mixed regarding the appropriate timing of surgery after ATCCS. Traditionally, this older population has been treated with delayed surgery because medical optimization is often indicated preoperatively. Surgically treated patients with ATCCS in the National Trauma Data Bank Research Data Set from 2011 and 2012 were identified. Time to surgery, Charlson Comorbidity Index, and injury severity scores were tested for association with mortality, serious adverse events, and minor adverse events using multivariate logistic regression. A total of 1060 patients with ATCCS met inclusion criteria. After controlling for pre-existing comorbidity and injury severity, delayed surgery was associated with a decreased odds of inpatient mortality (odds ratio = 0.81, P = 0.04), or a 19% decrease in odds of mortality with each 24-hour increase in time until surgery. The association of time to surgery with serious adverse events was not statistically significant (P = 0.09), whereas time to surgery was associated with increased odds of minor adverse events (odds ratio = 1.06, P < 0.001). Although the potential neurological effect of surgical timing for patients with ATCCS remains controversial, the decreased mortality with delayed surgery suggests that waiting to optimize general health and potentially allow for some spinal cord recovery in these patients may be advantageous. 3.

Our study compares breast cancer survivors without a secondary diagnosis of uterine cancer (BC) to breast cancer survivors with a diagnosis of uterine cancer (BUC) to determine clinical characteristics that increase the odds of developing uterine cancer. A total of 7,228 breast cancer survivors were surveyed. A case-control study was performed with 173 BUC patients matched by age and race in a 1:5 ratio to 865 BC patients. Multivariable logistic regression examined which factors influence the odds of developing uterine cancer. A total of 5,980 (82.3 %) women did not have a previous hysterectomy at the time of breast cancer diagnosis, of which 173 (2.9 %) subsequently developed uterine cancer. There was no significant difference in body mass index (BMI) (34.4 vs. 34.1, p = 0.388) or age (52.3 vs. 52.3 years, p = 0.999) between the two groups. Increased odds for developing uterine cancer were found in patients with a personal history of hypertension [odds ratio (OR) = 1.62, 95 % confidence interval (CI) 1.45-2.70, p < 0.001], gallbladder disease (OR = 1.30, 95 % CI 1.14-1.55, p = 0.005), and thyroid disease (OR = 1.55, 95 % CI 1.37-1.69, p < 0.001). More than 80 % of women in both groups expressed a desire for a blood test to estimate the risk of uterine cancer (80.4 % BUC vs. 91.2 % BC, p < 0.001). Hypertension, gallbladder disease, and thyroid disease in breast cancer survivors increase the odds of developing uterine cancer. Breast cancer survivors also express significant interest in potential serum tests to assess the risk of developing uterine cancer.

Discharge destination, either home or skilled care facility, after total knee arthroplasty (TKA) may be associated with significant variation in postacute care outcomes. The purpose of this study was to characterize the 30-day postdischarge outcomes after primary TKA relative to discharge destination. All primary unilateral TKAs performed for osteoarthritis from 2011-2014 were identified in the National Surgical Quality Improvement Program database. Propensity scores based on predischarge characteristics were used to adjust for selection bias in discharge destination. Propensity-adjusted multivariable logistic regressions were used to examine associations between discharge destination and postdischarge complications. Among 101,256 primary TKAs identified, 70,628 were discharged home and 30,628 to skilled care facilities. Patients discharged to facilities were more frequently were female, older, higher body mass index class, higher Charlson comorbidity index and American Society of Anesthesiologists scores, had predischarge complications, received general anesthesia, and classified as nonindependent preoperatively. Propensity adjustment accounted for this selection bias. Patients discharged to skilled care facilities after TKA had higher odds of any major complication (odds ratio = 1.25; 95% confidence interval, 1.13-1.37) and readmission (odds ratio = 1.81; 95% confidence interval, 1.50-2.18). Skilled care was associated with increased odds for respiratory, septic, thromboembolic, and urinary complications. Associations with death, cardiac, and wound complications were not significant. After controlling for predischarge characteristics, discharge to skilled care facilities vs home after primary TKA is associated with higher odds of numerous complications and unplanned readmission. These results support coordination of care pathways to facilitate home discharge after hospitalization for TKA whenever possible. Copyright © 2017 Elsevier Inc. All rights reserved.

Pulse pressure (PP) has been associated with atrial fibrillation (AF) independent of other measures of arterial pressure and other AF risk factors. However, the impact of gender, race, age, and geographic region on the association between PP and AF is unclear. A cross-sectional study of data from 25,109 participants (65 ± 9 years, 54% women, 40% black) from the Reasons for Geographic and Racial Differences in Stroke study recruited between 2003 and 2007 were analyzed. AF was defined as a self-reported history of a previous physician diagnosis or presence of AF on ECG. Multivariable logistic regression models were used to calculate the odds ratio for AF. Interactions for age (<75 years and ≥75 years), gender, race, and region were examined in the multivariable adjusted model. The prevalence of AF increased with widening PP (7.9%, 7.9%, 8.4%, and 11.6%, for PP < 45, 45-54.9, 55-64.9, and ≥65 mm Hg, respectively, [P for trend <.001]) but attenuated with adjustment. No differences by gender, race, and region were observed. However, there was evidence of significant effect modification by age (interaction P = .0002). For those <75 years, PP ≥ 65 mm Hg compared to PP < 45 mm Hg was significantly associated with higher risk of AF in both the unadjusted and multivariable adjusted models (odds ratio = 1.66 [95% CI = 1.42-1.94] and 1.32 [95% CI = 1.03-1.70], respectively). In contrast, higher PP (55-64.9 mm Hg) among those ≥75 years was significantly associated with a lower risk of AF. The relationship between PP and AF may differ for older versus younger individuals.

STUDY OBJECTIVE—The aim of this study was to investigate ethnic differences in self reported health in the city of Malmö, Sweden, and whether these differences could be explained by psychosocial and economic conditions.
DESIGN/SETTING/PARTICIPANTS—The public health survey in Malmö 1994 was a cross sectional study. A total of 5600 people aged 20-80 years completed a postal questionnaire. The participation rate was 71%. The population was categorised according to country of origin: born in Sweden, other Western countries, Yugoslavia, Poland, Arabic speaking countries and all other countries. The multivariate analysis was performed using a logistic regression model in order to investigate the importance of possible confounders on the differences by country of origin in self reported health. Finally, variables measuring psychosocial and economic conditions were introduced into the model.
MAIN RESULTS—The odds ratios of having poor self reported health were significantly higher among men born in other Western countries, Yugoslavia, Arabic speaking countries and in the category all other countries, as well as among women born in Yugoslavia, Poland and all other countries, compared with men and women born in Sweden. The multivariate analysis including age and education did not change these results. A huge reduction of the odds ratios was observed for men and women born in Yugoslavia, Arabic speaking countries and all other countries, and for women born in Poland after the introduction of the social network, social support and economic factors into the multivariate model.
CONCLUSIONS—There were significant ethnic group differences in self reported health. These differences were greatly reduced by psychosocial and economic factors, which suggest that these factors may be important determinants of self rated health in certain minority groups.

We studied the association between drinking water, agriculture and sporadic human campylobacteriosis in one region of British Columbia (BC), Canada. We compared 2992 cases of campylobacteriosis to 4816 cases of other reportable enteric diseases in 2005-2009 using multivariate regression. Cases were geocoded and assigned drinking water source, rural/urban environment and socioeconomic status (SES) according to the location of their residence using geographical information systems analysis methods. The odds of campylobacteriosis compared to enteric disease controls were higher for individuals serviced by private wells than municipal surface water systems (odds ratio 1·4, 95% confidence interval 1·1-1·8). In rural settings, the odds of campylobacteriosis were higher in November (P = 0·014). The odds of campylobacteriosis were higher in individuals aged ⩾15 years, especially in those with higher SES. In this region of BC, campylobacteriosis risk, compared to other enteric diseases, seems to be mediated by vulnerable drinking water sources and rural factors. Consideration should be given to further support well-water users and to further study the microbiological impact of agriculture on water.

With emphasis on value-based health care, empiric models are used to estimate expected readmission rates for individual institutions. The aim of this study was to determine the relationship between distance traveled to seek surgical care and likelihood of readmission in adult patients undergoing cardiac operations at a single medical center. All adults undergoing major cardiac surgeries from 2008 to 2015 were included. Patients were stratified by travel distance into regional and distant travel groups. Multivariable logistic regression models were developed to assess the impact of distance traveled on odds of readmission. Of the 4232 patients analyzed, 29 per cent were in the regional group and 71 per cent in the distant. Baseline characteristics between the two groups were comparable except mean age (62 vs 61 years, P < 0.01) and Caucasian race (59 vs 73%, P < 0.01). Distant travel was associated with a significantly longer hospital length of stay (11.8 vs 10.5 days, P < 0.01) and lower risk of readmission (9.5 vs 13.4%, P < 0.01). Odds of readmission was inversely associated with logarithm of distance traveled (odds ratio 0.75). Travel distance in patients undergoing major cardiac surgeries was inversely associated with odds of readmission.

Bovine neonatal pancytopenia (BNP; previously known as idiopathic haemorrhagic diathesis and commonly known as bleeding calf syndrome) is a novel haemorrhagic disease of young calves which has emerged in a number of European countries during recent years. Data were retrospectively collected during June to November 2010 for 56 case calves diagnosed with BNP between 17 March and 7 June of the same year. These were compared with 58 control calves randomly recruited from herds with no history of BNP. Multivariable logistic regression analysis showed that increased odds of a calf being a BNP case were associated with its dam having received PregSure® BVD (Pfizer Animal Health) vaccination prior to the birth of the calf (odds ratio (OR) 40.78, p<0.001) and its herd of origin being located in Scotland (OR 9.71, p = 0.006). Decreased odds of a calf being a BNP case were associated with the calf having been kept outside (OR 0.11, p = 0.006). The longer that a cattle herd had been established on the farm was also associated with decreased odds of a calf in that herd being a BNP case (OR 0.97, p = 0.011). PMID:22606224

Objectives. We examined purging for weight control, diet pill use, and obesity across sexual orientation identity and ethnicity groups. Methods. Anonymous survey data were analyzed from 24 591 high school students of diverse ethnicities in the federal Youth Risk Behavioral Surveillance System Survey in 2005 and 2007. Self-reported data were gathered on gender, ethnicity, sexual orientation identity, height, weight, and purging and diet pill use in the past 30 days. We used multivariable logistic regression to estimate odds of purging, diet pill use, and obesity associated with sexual orientation identity in gender-stratified models and examined for the presence of interactions between ethnicity and sexual orientation. Results. Lesbian, gay, and bisexual (LGB) identity was associated with substantially elevated odds of purging and diet pill use in both girls and boys (odds ratios [OR] range =  1.9–6.8). Bisexual girls and boys were also at elevated odds of obesity compared to same-gender heterosexuals (OR = 2.3 and 2.1, respectively). Conclusions. Interventions to reduce eating disorders and obesity that are appropriate for LGB youths of diverse ethnicities are urgently needed. PMID:23237207

Despite ongoing efforts to improve therapy in malignant pleural mesothelioma, few patients undergoing extrapleural pneumonectomy experience long-term survival (LTS). This study aims to explore predictors of LTS after extrapleural pneumonectomy and to define a prognostic score. From January 2000 to December 2010, we retrospectively reviewed clinicopathologic and oncological factors in a multicenter cohort of 468 malignant pleural mesothelioma patients undergoing extrapleural pneumonectomy. LTS was defined as survival longer than 3 years. Associations were evaluated using χ(2), Student's t, and Mann-Whitney U tests. Logistic regression, Cox regression hazard model, and bootstrap analysis were applied to identify outcome predictors. Survival curves were calculated by the Kaplan-Meier method. Receiver operating characteristic analyses were used to estimate optimal cutoff and area under the curve for accuracy of the model. Overall, 107 patients (22.9%) survived at least 3 years. Median overall, cancer-specific, and disease-free survival times were 60 (95% confidence interval [CI], 51 to 69), 63 (95% CI, 54 to 72), and 49 months (95% CI, 39 to 58), respectively. At multivariate analysis, age (odds ratio, 0.51; 95% CI, 0.31 to 0.82), epithelioid histology (odds ratio, 7.07; 95% CI, 1.56 to 31.93), no history of asbestos exposure (odds ratio, 3.13; 95% CI, 1.13 to 8.66), and the ratio between metastatic and resected lymph nodes less than 22% (odds ratio, 4.12; 95% CI, 1.68 to 10.12) were independent predictors of LTS. According to these factors, we created a scoring system for LTS that allowed us to correctly predict overall, cancer-specific, and disease-free survival in the total sample, obtaining two different groups with favorable or poor prognosis (area under the curve, 0.74; standard error, 0.04; p < 0.0001). Our prognostic model facilitates the prediction of LTS after surgery for malignant pleural mesothelioma and can help to stratify the outcome and, eventually, tailor postoperative treatment.

The risk for atrial fibrillation-associated stroke increases at low anticoagulation intensities. However, higher intensities increase hemorrhage risk. Optimal use of warfarin for atrial fibrillation requires precise information on the risk for intracranial hemorrhage as a function of patient age and anticoagulation intensity. To examine the relationship of age, anticoagulation intensity, and risk for intracranial hemorrhage. Case-control study. Academic medical center. 170 case-patients who developed intracranial hemorrhage during warfarin therapy and 1020 matched controls who did not; both case-patients and controls were taking warfarin for atrial fibrillation. The authors performed multivariable conditional logistic regression to determine the odds of intracranial hemorrhage with regard to age and international normalized ratio (INR), controlling for comorbid conditions and aspirin use. Case-patients were older than controls (median age, 78 years vs. 75 years; P < 0.001) and had higher median INRs (2.7 vs. 2.3; P < 0.001). The risk for intracranial hemorrhage increased at 85 years of age or older (adjusted odds ratio, 2.5 [95% CI, 1.3 to 4.7]; referent age, 70 to 74 years) and at an INR range of 3.5 to 3.9 (adjusted odds ratio, 4.6 [CI, 2.3 to 9.4]; referent INR, 2.0 to 3.0). The risk for intracranial hemorrhage at INRs less than 2.0 did not differ statistically from the risk at INRs of 2.0 to 3.0 (adjusted odds ratio, 1.3 [CI, 0.8 to 2.2]). Although duration of anticoagulation has been associated with hemorrhage in other studies, the current study could not control for this potential confounder. The risk for intracranial hemorrhage increases at age 85 years. International normalized ratios less than 2.0 were not associated with lower risk for intracranial hemorrhage compared with INRs between 2.0 and 3.0. Therefore, anticoagulation management should focus on maintaining INRs in the 2.0 to 3.0 range, even in elderly patients with atrial fibrillation, rather than targeting INRs less than 2.0. Similarly, INRs of 3.5 or greater should be avoided.

The safety of healthy living donors undergoing hepatic resection for living-donor liver transplantation is of paramount concern. Although blood transfusions have been associated with morbidity and mortality after hepatectomy, there is limited information about the risk factors associated with blood transfusion in living liver donors. We retrospectively analyzed 2344 donors who underwent a hepatectomy for living-donor liver transplantation. Logistic regression analysis was performed to determine blood transfusion predictors in living-donor hepatectomy. Of these donors, 48 (2.0%) and 97 (4.1%) were transfused with packed red blood cell (PRBC) and fresh-frozen plasma (FFP), respectively. The amount of PRBC and FFP administered to donors transfused with blood products were 1.9±0.8 and 3.7±2.5 units, respectively. In multivariate logistic regression analysis, a low preoperative hemoglobin level was found to be an independent predictor of PRBC transfusion in donor hepatectomy (odds ratio=0.585; 95% confidence interval=0.451-0.758; P<0.001). A high graft-to-donor weight ratio predicted an FFP transfusion in donor hepatectomy (odds ratio=2.997; 95% confidence interval=1.226-7.327; P=0.016). These results indicate that, in donor hepatectomy, the preoperative hemoglobin value and graft-to-donor weight ratio can provide useful information on the probability of PRBC and FFP transfusion, respectively.

The aim of this study was to determine the relationship between lobar severity of emphysema and lung cancer using automated lobe segmentation and emphysema quantification methods.This study included 78 patients (74 males and 4 females; mean age of 72 years) with the following conditions: pathologically proven lung cancer, available chest computed tomographic (CT) scans for lobe segmentation, and quantitative scoring of emphysema. The relationship between emphysema and lung cancer was analyzed using quantitative emphysema scoring of each pulmonary lobe.The most common location of cancer was the left upper lobe (LUL) (n = 28), followed by the right upper lobe (RUL) (n = 27), left lower lobe (LLL) (n = 13), right lower lobe (RLL) (n = 9), and right middle lobe (RML) (n = 1). Emphysema ratio was the highest in LUL, followed by that in RUL, LLL, RML, and RLL. Multivariate logistic regression analysis revealed that upper lobes (odds ratio: 1.77; 95% confidence interval: 1.01-3.11, P = 0.048) and lobes with emphysema ratio ranked the 1st or the 2nd (odds ratio: 2.48; 95% confidence interval: 1.48-4.15, P < 0.001) were significantly and independently associated with lung cancer development.In emphysema patients, lung cancer has a tendency to develop in lobes with more severe emphysema.

Contemporary real-world data on clinical outcomes after utilization of coronary atherectomy are sparse. The study cohort was derived from Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from year 2012. Percutaneous coronary interventions including atherectomy were identified using appropriate International Classification of Diseases, 9th Revision diagnostic and procedural codes. Two-level hierarchical multivariate mixed models were created. The primary outcome was a composite of in-hospital mortality and periprocedural complications; the secondary outcome was in-hospital mortality. Hospitalization costs were also assessed. A total of 107,131 procedures were identified in 2012. Multivariate analysis revealed that atherectomy utilization was independently predictive of greater primary composite outcome of in-hospital mortality and complications (odds ratio 1.34, 95% confidence interval 1.22 to 1.47, p <0.001) but was not associated with any significant difference in terms of in-hospital mortality alone (odds ratio 1.22, 95% confidence interval 0.99 to 1.52, p 0.063). In the propensity-matched cohort, atherectomy utilization was again associated with a higher rate of complications (12.88% vs 10.99%, p = 0.001), in-hospital mortality +a ny complication (13.69% vs 11.91%, p = 0.003) with a nonsignificant difference in terms of in-hospital mortality alone (3.45% vs 2.88%, p = 0.063) and higher hospitalization costs ($25,341 ± 353 vs $21,984 ± 87, p <0.001). Atherectomy utilization during percutaneous coronary intervention is associated with a higher rate of postprocedural complications without any significant impact on in-hospital mortality.

According to the published work, pregnancy termination rates due to prenatal diagnosis of fetal sex chromosome aneuploidies (SCA) vary widely. Some potentially modifiable and non-modifiable factors have been reported to be associated with parental decision. This study aimed to evaluate the rate of pregnancy termination for fetal SCA and the factors influencing parents' decisions in Hong Kong. This was a 21-year retrospective cohort study of parents' decisions following prenatal diagnosis of SCA. Univariate and multivariate analyses for the association between demographic factors, prenatal factors, or counseling provided and decision-making were conducted. The study included 399 pregnancies with prenatal diagnosis of SCA and the overall termination rate was 55.6% (91.7%, 48.0%, 23.4%, 4.8%, and 22.7% for 45,X, 47,XXY, 47,XXX, 47,XYY, and mosaicism, respectively). Pregnancies with ultrasound abnormalities were associated with higher termination rates than pregnancies with normal ultrasound findings (91.3% vs 28.3%, P < 0.0001). From multivariate regression analysis on 226 pregnancies with normal ultrasound examination, a higher likelihood to terminate was found in pregnancies affected by 45,X and 47,XXY (adjusted odds ratio, 4.72, P < 0.0001). Increased maternal age and history of infertility were associated with lower likelihood to terminate (adjusted odds ratio, 0.9, P = 0.012; and 5.12, P = 0.038, respectively). The pregnancy termination rate declined over time. A significant correlation was found between the termination of SCA-affected pregnancy and the presence of fetal sonographic abnormalities, type of SCA, maternal age, and presence of infertility. © 2017 Japan Society of Obstetrics and Gynecology.

The objective of this study was to investigate risk factors associated with tuberculosis (TB) transmission that was caused by Mycobacterium tuberculosis strain MS0006 from 2004 to 2009 in Hinds County, Mississippi. DNA fingerprinting using spoligotyping, mycobacterial interspersed repetitive unit, and IS6110-based restriction fragment length polymorphism of culture-confirmed cases of TB was performed. Clinical and demographic factors associated with strain MS0006 were analyzed by univariate and multivariate analysis. Of the 144 cases of TB diagnosed during the study period, 117 were culture positive with fingerprints available. There were 48 different strains, of which 6 clustered strains were distributed among 74 patients. The MS0006 strain accounted for 46.2% of all culture-confirmed cases. Risk factors for having the MS0006 strain in a univariate analysis included homelessness, HIV co-infection, sputum smear negativity, tuberculin skin test negativity, and noninjectable drug use. Multivariate analysis identified homelessness (odds ratio 7.88, 95% confidence interval 2.90-21.35) and African American race (odds ratio 5.80, 95% confidence interval 1.37-24.55) as independent predictors of having TB caused by the MS0006 strain of M. tuberculosis. Our findings suggest that a majority of recently transmitted TB in the studied county was caused by the MS0006 strain. African American race and homelessness were significant risk factors for inclusion in the cluster. Molecular epidemiology techniques continue to provide in-depth analysis of disease transmission and play a vital role in effective contact tracing and interruption of ongoing transmission.

Purpose The fragile-site associated tumor suppressor (FATS) is a newly identified tumor suppressor involved in radiation-induced tumorigenesis. The purpose of this study was to characterize FATS expression in breast cancers about radiotherapy benefit, patient characteristics, and prognosis. Results The expression of FATS mRNA was silent or downregulated in 95.2% of breast cancer samples compared with paired normal controls (P < .0001). Negative status of FATS was correlated with higher nuclear grade (P = .01) and shorter disease-free survival (DFS) of breast cancer (P = .036). In a multivariate analysis, FATS expression showed favorable prognostic value for DFS (odds ratio, 0.532; 95% confidence interval, 0.299 to 0.947; (P = .032). Furthermore, improved survival time was seen in FATS-positive patients receiving radiotherapy (P = .006). The results of multivariate analysis revealed independent prognostic value of FATS expression in predicting longer DFS (odds ratio, 0.377; 95% confidence interval, 0.176 to 0.809; P = 0.012) for patients receiving adjuvant radiotherapy. In support of this, reduction of FATS expression in breast cancer cell lines, FATS positive group significantly sensitized than Knock-down of FATS group. Materials and Methods Tissue samples from 156 breast cancer patients and 42 controls in tumor bank were studied. FATS gene expression was evaluated using quantitative reverse transcription polymerase chain reaction (qRT-PCR). FATS function was examined in breast cancer cell lines using siRNA knock-downs and colony forming assays after irradiation. Conclusions FATS status is a biomarker in breast cancer to identify individuals likely to benefit from radiotherapy. PMID:28402275

We evaluated the prevalence and correlates of intimate partner violence in the past year by a regular male partner in HIV-positive female sex workers in Mombasa, Kenya. This cross-sectional study included HIV-positive women ≥ 18 years old who reported engagement in transactional sex at the time of enrolment in the parent cohort. We asked 13 questions adapted from the World Health Organization survey on violence against women about physical, sexual, or emotional violence in the past year by the current or most recent emotional partner (index partner). We used standardised instruments to assess socio-demographic and behavioural characteristics as possible correlates of intimate partner violence. Associations between intimate partner violence and these correlates were evaluated using univariate and multivariate logistic regression. Overall, 286/357 women (80.4%) had an index partner, and 52/357 (14.6%, 95% confidence interval 10.9%–18.2%) reported intimate partner violence by that partner in the past year. In multivariate analysis, women with severe alcohol problems (adjusted odds ratio 4.39, 1.16–16.61) and those experiencing controlling behaviours by the index partner (adjusted odds ratio 4.98, 2.31–10.74) were significantly more likely to report recent intimate partner violence. Recent intimate partner violence was common in HIV-positive female sex workers. Interventions targeting risk factors for intimate partner violence, including alcohol problems and partner controlling behaviours, could help to reduce recurrent violence and negative health outcomes in this key population.

Proteinuria is a marker of vascular dysfunction that predicted increased cardiovascular mortality and is associated with neurocognitive impairment (NCI) in population-based studies. We examined associations between proteinuria and HIV-associated NCI. Multivariable logistic regression was used to examine associations between NCI at the first neurocognitive assessment (baseline) and simultaneous, clinically significant proteinuria [as random spot urine protein-to-creatinine ratios (UP/Cr) ≥200 mg/g] in a prospective multicenter observational cohort study. Generalized estimating equations were used to examine associations between baseline proteinuria and subsequent NCI among subjects without NCI at baseline. NCI was defined as a Z-score, derived from the combination of normalized scores from the Trailmaking A and B and the Wechsler Adult Intelligence Scale-Revised Digit Symbol tests. A total of 1972 subjects were included in this analysis. Baseline proteinuria was associated with increased odds of NCI [odds ratio (OR): 1.41, 95% confidence interval (CI): 1.08 to 1.85; P = 0.01] and with subsequent NCI among subjects without NCI at baseline (OR: 1.39, 95% CI: 1.01 to 1.93; P = 0.046) in multivariable models adjusted for risk factors and potential confounders. Similar associations were evident when these analyses were limited to visits at which time study subjects maintained plasma HIV RNA levels <200 copies per milliliter. The association between proteinuria and NCI observed in this study adds to a growing body of evidence implicating contributions by vascular disease to NCI in antiretroviral treated individuals. Studies examining interventions that improve vascular function are warranted.

Staphylococcus aureus (SA) breast abscesses are a complication of the postpartum period. Risk factors for postpartum SA breast abscesses are poorly defined, and literature is conflicting. Whether risk factors for methicillin-resistant SA (MRSA) and methicillin-susceptible SA (MSSA) infections differ is unknown. We describe novel risk factors associated with postpartum breast abscesses and the changing epidemiology of this infection. We conducted a cohort study with a nested case-control study (n = 216) involving all patients with culture-confirmed SA breast abscess among >30 000 deliveries at our academic tertiary care center from 2003 through 2010. Data were collected from hospital databases and through abstraction from medical records. All SA cases were compared with both nested controls and full cohort controls. A subanalysis was completed to determine whether risk factors for MSSA and MRSA breast abscess differ. Univariate analysis was completed using Student's t test, Wilcoxon rank-sum test, and analysis of variance, as appropriate. A multivariable stepwise logistic regression was used to determine final adjusted results for both the case-control and the cohort analyses. Fifty-four cases of culture-confirmed abscess were identified: 30 MRSA and 24 MSSA. Risk factors for postpartum SA breast abscess in multivariable analysis include in-hospital identification of a mother having difficulty breastfeeding (odds ratio, 5.00) and being a mother employed outside the home (odds ratio, 2.74). Risk factors did not differ between patients who developed MRSA and MSSA infections. MRSA is an increasingly important pathogen in postpartum women; risk factors for postpartum SA breast abscess have not changed with the advent of community-associated MRSA.

PurposeTo report hepatic arterial-related complications encountered during planning and treatment angiograms for radioembolization and understand any potential-associated risk factors.Materials and Methods518 mapping or treatment angiograms for 180 patients with primary or metastatic disease to the liver treated by Yttrium-90 radioembolization between 2/2010 and 12/2015 were retrospectively reviewed. Intra-procedural complications were recorded per SIR guidelines. Patient demographics, indication for treatment, prior exposure to chemotherapeutic agents, operator experience, and disease burden were reviewed. Technical variables including type of radioembolic (glass vs. resin microspheres), indication for angiography (mapping vs. treatment), variant anatomy, and attempts at coil embolization were also assessed.ResultsThirteen (13/518, 2.5%) arterial-relatedmore » complications occurred in 13 patients. All but two complications resulted during transcatheter coil embolization to prevent non-target embolization. Complications included coil migration (n = 6), arterial dissection (n = 2), focal vessel perforation (n = 2), arterial thrombus (n = 2), and vasospasm prohibiting further arterial sub-selection (n = 1). Transarterial coiling was identified as a significant risk factor of complications on both univariate and multivariate regression analysis (odds ratio 7.8, P = 0.004). Usage of resin microspheres was also a significant risk factor (odds ratio 9.5, P = 0.042). No other technical parameters or pre-procedural variables were significant after adjusting for confounding on multivariate analysis (P > 0.05).ConclusionIntra-procedural hepatic arterial complications encountered during radioembolization were infrequent but occurred mainly during coil embolization to prevent non-target delivery to extra-hepatic arteries.« less

Corneal transplantation is the treatment of choice for many corneal diseases. At present, there is a global shortage of corneal transplant tissues, and failure to obtain consent from families of potential donors is a major limiting factor in tissue procurement. All family members of potential donors after cardiac death approached by the local eye bank staff members from January 2008 to December 2014 in Hong Kong were included. Reasons for consent or refusal and sociodemographic details of the deceased and the family members approached were reviewed. Trends in consent rates from 2008 to 2014 were examined. Multivariable logistic regression was performed to examine determinants of donation among cases from 2013 to 2014. A total of 1740 cases were identified. The overall consent rate was 36.8%, and the consent rate did not change significantly over the 7-year study period (P = 0.24). The most common reason for consent by family members was "the wish to help others" (86.0%), and the most common reason for refusal was "traditional Chinese culture to keep the body intact after death" (42.7%). From the multivariable analysis in the subset of cases from 2013 to 2014 (n = 628), family members were more likely to consent when the deceased was female (adjusted odds ratio 1.45, P = 0.03), with a do-not-resuscitate order (adjusted odds ratio 2.27, P < 0.001). The consent rate for eye donation did not change significantly from 2008 to 2014. Our findings suggest that health education and promotion campaigns need to address cultural barriers to organ donation.

In the United States, black men who have sex with men (BMSM) are disproportionately affected by the HIV epidemic. The elevated estimates of HIV among BMSM suggest that to slow rates of HIV infections, a range of factors that may contribute to transmission must be researched. Use of online venues for seeking out sex partners is one such area that may further advance our understanding of risks for HIV among BMSM. Black men who have sex with men residing in Atlanta, GA, reporting HIV-negative/unknown status completed survey assessments and HIV antibody testing. Logistic regression using generalized linear modeling was used to conduct both bivariate and multivariable analyses of psychosocial variables-that is, substance use, sexually transmitted infection symptoms/diagnoses, sexual risk behavior, online sex partner meeting, and HIV test results. Two hundred thirty-two BMSM tested HIV negative and 39 BMSM tested HIV positive (14% new diagnoses). Reporting symptoms of a rectal sexually transmitted infection (odds ratio, 4.28; 95% confidence interval, 1.06-15.41) and use of sexual networking apps (odds ratio, 2.15; 95% confidence interval, 1.06-4.36) were both associated with testing HIV positive in a multivariable analysis. The use of sexual networking apps is associated with risks for HIV infection above and beyond what is captured by sexual risk behavior alone. Evaluating how sexual networking apps affect sexual networks and social norms regarding sexual risk taking and HIV transmission is an important and novel area for HIV prevention and intervention development.

We aimed to examine the concurrent effects of timing and intensity of rehabilitation on improving activities of daily living (ADL) among patients with ischemic stroke. Using the Japanese Diagnosis Procedure Combination inpatient database, we retrospectively analyzed consecutive patients with ischemic stroke at admission who received rehabilitation (n=100 719) from April 2012 to March 2014. Early rehabilitation was defined as that starting within 3 days after admission. The average rehabilitation intensity per day was calculated as the total units of rehabilitation during hospitalization divided by the length of hospital stay. A multivariable logistic regression analysis with multiple imputation and an instrumental variable analysis were performed to examine the association of early and intensive rehabilitation with the proportion of improved ADL score. The proportion of improved ADL score was higher in the early and intensive rehabilitation group. The multivariable logistic regression analysis showed that significant improvements in ADL were observed for early rehabilitation (odds ratio: 1.08; 95% confidence interval: 1.04-1.13; P <0.01) and intensive rehabilitation of >5.0 U/d (odds ratio: 1.87; 95% confidence interval: 1.69-2.07; P <0.01). The instrumental variable analysis showed that an increased proportion of improved ADL was associated with early rehabilitation (risk difference: 2.8%; 95% confidence interval: 2.0-3.4%; P <0.001) and intensive rehabilitation (risk difference: 5.6%; 95% confidence interval: 4.6-6.6%; P <0.001). The present results suggested that early and intensive rehabilitation improved ADL during hospitalization in patients with ischemic stroke. © 2017 American Heart Association, Inc.

Background: Recent studies have examined sugar-sweetened soda consumption in relation to early markers of kidney disease, but to date there have been no investigations of whether sugar-sweetened beverage consumption affects preexistent chronic kidney disease (CKD). Objective: This prospective cohort study of 447 participants in the Multi-Ethnic Study of Atherosclerosis (MESA) with preexistent CKD examined the association between sugar-sweetened beverage consumption (<1 drink/wk, 1–6 drinks/wk, and ≥1 drink/d) and progression of CKD. Design: β-Coefficients for continuous outcomes of changes in estimated glomerular filtration rate (eGFR) and urinary albumin to creatinine ratio (UACR) were calculated by using linear regression. Odds ratios for binary outcomes of accelerated decline in eGFR, defined as >2 mL · min−1 · 1.73 m−2 per year, and clinically significant progression of albuminuria (defined as attainment of UACR ≥30 mg/g for participants without microalbuminuria at visit 1 or a ≥25% increase in UACR for participants with baseline microalbuminuria) were evaluated by using logistic regression. Results: The mean (±SD) baseline eGFR was 52 ± 6 mL · min−1 · 1.73 m−2 per year, and median baseline UACR was 6.3 mg/g (interquartile range: 3.5–17.6). Univariate and multivariate analyses showed no association between sugar-sweetened beverage consumption and rate of eGFR decline or changes in urinary albumin to creatinine ratio. The multivariate odds ratios comparing participants who drank ≥1 sugary beverage daily with those who drank ≤1 beverage weekly were 0.62 (95% CI: 0.27, 1.41) for accelerated eGFR decline and 1.51 (95% CI: 0.49, 4.62) for clinically significant progression of albuminuria. Conclusion: A higher consumption of sugar-sweetened beverages was not associated with disease progression, on the basis of either eGFR or the urinary albumin to creatinine ratio, in MESA participants with preexistent CKD.

Failure to rescue (FTR), the mortality rate among surgical patients with complications, is an emerging quality indicator. Hospitals with a high safety-net burden, defined as the proportion of patients covered by Medicaid or uninsured, provide a disproportionate share of medical care to vulnerable populations. Given the financial strains on hospitals with a high safety-net burden, availability of clinical resources may have a role in outcome disparities. To assess the association between safety-net burden and FTR and to evaluate the effect of clinical resources on this relationship. A retrospective cohort of 46,519 patients who underwent high-risk inpatient surgery between January 1, 2007, and December 31, 2010, was assembled using the Nationwide Inpatient Sample. Hospitals were divided into the following 3 safety-net categories: high-burden hospitals (HBHs), moderate-burden hospitals (MBHs), and low-burden hospitals (LBHs). Bivariate and multivariate analyses controlling for patient, procedural, and hospital characteristics, as well as clinical resources, were used to evaluate the relationship between safety-net burden and FTR. FTR. Patients in HBHs were younger (mean age, 65.2 vs 68.2 years; P = .001), more likely to be of black race (11.3% vs 4.2%, P < .001), and less likely to undergo an elective procedure (39.3% vs 48.6%, P = .002) compared with patients in LBHs. The HBHs were more likely to be large, major teaching facilities and to have high levels of technology (8.6% vs 4.0%, P = .02), sophisticated internal medicine (7.7% vs 4.3%, P = .10), and high ratios of respiratory therapists to beds (39.7% vs 21.1%, P < .001). However, HBHs had lower proportions of registered nurses (27.9% vs 38.8%, P = .02) and were less likely to have a positron emission tomographic scanner (15.4% vs 22.0%, P = .03) and a fully implemented electronic medical record (12.6% vs 17.8%, P = .03). Multivariate analyses showed that HBHs (adjusted odds ratio, 1.35; 95% CI, 1.19-1.53; P < .001) and MBHs (adjusted odds ratio, 1.15; 95% CI, 1.05-1.27; P = .005) were associated with higher odds of FTR compared with LBHs, even after adjustment for clinical resources. Despite access to resources that can improve patient rescue rates, HBHs had higher odds of FTR, suggesting that availability of hospital clinical resources alone does not explain increased FTR rates.

AIMS—A case-control study was performed to evaluate soft contact lens (SCL) wear modality as a risk factor for microbial keratitis.
METHODS—Contact lens wearers presenting as new patients to Moorfields Eye Hospital accident and emergency department during a 12 month period completed a self administered questionnaire detailing demographic data and contact lens use habits. Cases were patients with a clinical diagnosis of SCL related microbial keratitis. Controls were SCL users attending with disorders unrelated to contact lens wear. Odds ratios (estimates of relative risks) and 95% confidence limits (CL) were calculated through multivariable logistic regression analysis.
RESULTS—There were 89 cases and 566 controls. A substantially increased risk with 1-4 weekly disposable SCL compared with non-disposable SCL was identified among both daily wear (DW) (odds ratio =3.51, 95% CL 1.60-7.66, p=0.002) and extended wear (odds ratio 4.76, 95% CL 1.52-14.87, p=0.007) users after adjustment for demographic, lens use and hygiene variables. Other significant factors among DW users were "occasional" overnight use, use of chlorine based (as opposed to other chemical) systems in combination with poor storage case hygiene, and irregular disinfection.
CONCLUSION—Properties of some disposable SCL may be partly responsible for these excess risks. It is also possible, however, that this finding is largely a reflection of widespread complacency among patients and practitioners with respect to disposable SCL fitting and use.

The study explores the association between sex and care dependency risk one year after stroke. The study uses claims data from a German statutory health insurance fund. Patients were included if they received a diagnosis of ischemic or hemorrhagic stroke between 1 January and 31 December 2007 and if they survived for one year after stroke and were not dependent on care before the event (n = 1851). Data were collected over a one-year period. Care dependency was defined as needing substantial assistance in activities of daily living for a period of at least six months. Geriatric conditions covered ICD-10 symptom complexes that characterize geriatric patients (e.g. urinary incontinence, cognitive deficits, depression). Multivariate regression analyses were performed. One year after the stroke event, women required nursing care significantly more often than men (31.2% vs. 21.3%; odds ratio for need of assistance: 1.67; 95% CI: 1.36-2.07). Adjusted for age, the odds ratio decreased by 65.7% to 1.23 (n.s.). Adjusted for geriatric conditions, the odds ratio decreased further and did not remain significant (adjusted OR: 1.18 (CI: 0.90-1.53). It may be assumed that women have a higher risk of becoming care-dependent after stroke than men because they are older and suffer more often from geriatric conditions such as urinary incontinence at onset of stroke. Preventive strategies should therefore focus on geriatric conditions in order to reduce the post-stroke care dependency risk for women.

Analyze acute respiratory distress syndrome (ARDS) in patients admitted to an Intensive Care Medicine Service (ICMS) and prognostic factors of mortality in these patients. Prospective study of all the patients admitted consecutively in the ICMS from January 1998 to February 2003. ICMS of a third level university site with 32 beds in its General Area and 10 beds in the Traumatology Area. Patients who met the ARDS criteria of the European-North American Consensus Conference at any time during admission in ICMS. ENDPOINTS OF INTEREST: Mortality at 28 days. One hundred and ninety-one patients (3.4 of all the admissions in ICMS) had ARDS criteria. The origin of ARDS was intrapulmonary in 63%. A total of 77% of the patients had multiorgan dysfunction and 26% respiratory superinfection. Median stay in the ICMS was 20 days. Mortality at 28 days was 48% and hospital mortality 58%. Multivariant analysis showed that the variables associated independently with an increase in mortality were the following: APACHE II > 22 (odds ratio [OR] 2.7; 95% CI: 1.3-5.8; p = 0.007), minimum PaO2/FIO2 during evolution of ARDS < 81 mmHg (odds ratio 5.5; 95% CI: 2.6-11.9; p < 0.0001), dysfunction > or = 3 organs (odds ratio 11.8; 95% CI: 2.5-55.4; p = 0.002). ARDS is an entity with elevated mortality whose prognosis is associated not only with the seriousness of pulmonary function deterioration but also of systemic function, on which some treatment could modulate its evolution.

Indoor tanning increases skin cancer risk. Beyond early research describing melanoma and sun lamps, few recent reports describe where individuals indoor tan and whether skin cancer risk varies by location (business, home-based). We sought to assess where individuals tanned indoors and skin cancer risk by tanning device location. Multivariate logistic regression was conducted in 2 US case-control studies of melanoma (1161 cases, 1083 controls, ages 25-59 years) and early-onset basal cell carcinoma (375 cases, 382 controls, age<40 years) conducted between 2004 and 2010. Most indoor tanners (86.4%-95.1%), especially younger individuals, tanned exclusively in businesses. Persons who used indoor tanning exclusively in businesses were at increased risk of melanoma (odds ratio 1.82, 95% confidence interval 1.47-2.26) and basal cell carcinoma (odds ratio 1.69, 95% confidence interval 1.15-2.48) compared with non-users. Melanoma risk was also increased in the small number who reported tanning indoors only at home relative to non-users (odds ratio 4.14, 95% confidence interval 1.75-9.78); 67.6% used sun lamps. Self-reported tanning and potential recall bias are limitations. Business-only tanning, despite claims of "safe" tanning, was positively associated with a significant risk of melanoma and basal cell carcinoma. Home tanning was uncommon and mostly from sun lamps, which were rarely used by younger participants. Regardless of location, indoor tanning was associated with increased risk of skin cancer.

Objective Long term effects of perineal tears pose a major worldwide health issue for women during delivery. Since bacterial vaginosis is related to major obstacles in obstetrics the aim of this study was to determine the relationship between bacterial vaginosis and the occurrence of perineal tears during vaginal delivery. Methods Between June 2013 and December 2013 pregnant women delivering after 37 weeks were recruited at one University hospital / tertiary care referral center in the course of this single-center, prospective cohort study. Bacterial vaginosis was assessed according to Nugent score method. Logistic-regression model was used to estimate odds ratios, adjusted for other risk factors to test the relationship between bacterial vaginosis and the occurrence of 1st to 4th degree perineal tears in women undergoing vaginal delivery. Results A total of 728 woman were included, 662 analyzed with a complete Nugent Score of the vaginal swab. The prevalence of 1st to 4th degree perineal tears was 35.8% (95% Confidence Interval (95%CI) = [32.2; 39.6]). The presence of BV was not significantly associated to the incidence of perineal tears neither in the univariate analysis (crude Odds Ratio = 1.43; 95%CI = [0.79; 2.60]; p = 0.235) nor in the multivariate analysis (adjusted Odds Ratio = 1.65; 95%CI = [0.81; 3.36]; p = 0.167). Instrumental delivery was the most important risk factor for perineal lacerations. Conclusions There is no evidence that vaginosis is a risk factor for vaginal tears.

To identify the incidence and associated factors of the postoperative hydronephrosis in pediatric patients who underwent ureterorenoscopy (URS) for renal or ureteral stones. We evaluated the results of 116 patients who underwent semirigid or flexible URS retrospectively. Primary end points of the study were to determine the incidence of postoperative hydronephrosis and factors associated with the development of postoperative hydronephrosis. Logistic regression analysis was used to define factors associated with the presence of hydronephrosis. Mean age of the population was 9.5 years and mean stone size was 9.4 mm. Hydronephrosis was detected in 32 (27.6%) patients. Stone-free status was achieved in 101 (87%) patients. Univariate analysis revealed history of ipsilateral URS, duration of operation, presence of impacted stone, development of ureteral injury during operation, and presentation with a renal colic episode as the parameter associated with increased risk of hydronephrosis. History of ipsilateral URS (odds ratio: 1.664, P = .027), presence of impacted stones (odds ratio: 1.788, P = .014), and development of ureteral injury during operation (odds ratio: 1.106, P = .039) were found to be the independent markers of developing postoperative hydronephrosis in a multivariate analysis. Ipsilateral hydronephrosis following URS develops in a significant portion of patients. In patients with history of ipsilateral procedure and those with an impacted stone and had ureteral injury, the risk of postoperative hydronephrosis is higher; therefore, physicians should keep these parameters in mind in the decision-making process of selective imaging postoperatively.

Growing evidence from experimental animal models and clinical studies suggests the protective effect of statin use against rupture of intracranial aneurysms; however, results from large studies detailing the relationship between intracranial aneurysm rupture and total cholesterol, HDL (high-density lipoprotein), LDL (low-density lipoprotein), and lipid-lowering agent use are lacking. The medical records of 4701 patients with 6411 intracranial aneurysms diagnosed at the Massachusetts General Hospital and the Brigham and Women's Hospital between 1990 and 2016 were reviewed and analyzed. Patients were separated into ruptured and nonruptured groups. Univariable and multivariable logistic regression analyses were performed to determine the effects of lipids (total cholesterol, LDL, and HDL) and lipid-lowering medications on intracranial aneurysm rupture risk. Propensity score weighting was used to account for differences in baseline characteristics of the cohorts. Lipid-lowering agent use was significantly inversely associated with rupture status (odds ratio, 0.58; 95% confidence interval, 0.47-0.71). In a subgroup analysis of complete cases that includes both lipid-lowering agent use and lipid values, higher HDL levels (odds ratio, 0.95; 95% confidence interval, 0.93-0.98) and lipid-lowering agent use (odds ratio, 0.41; 95% confidence interval, 0.23-0.73) were both significantly and inversely associated with rupture status, whereas total cholesterol and LDL levels were not significant. A monotonic exposure-response curve between HDL levels and risk of aneurysmal rupture was obtained. Higher HDL values and the use of lipid-lowering agents are significantly inversely associated with ruptured intracranial aneurysms. © 2018 American Heart Association, Inc.

Today's healthcare environment is often characterized by an ethically demanding work situation, and nursing students need to prepare to meet ethical challenges in their future role. Moral sensitivity is an important aspect of the ethical decision-making process, but little is known regarding nursing students' moral sensitivity and its possible development during nursing education. The aims of this study were to investigate moral sensitivity among nursing students, differences in moral sensitivity according to sample sub-group, and the relation between demographic characteristics of nursing students and moral sensitivity. A convenience sample of 299 nursing students from one university completed a questionnaire comprising questions about demographic information and the revised Moral Sensitivity Questionnaire. With the use of SPSS, non-parametric statistics, including logistic regression models, were used to investigate the relationship between demographic characteristics and moral sensitivity. Ethical considerations: The study followed the regulations according to the Swedish Ethical Review Act and was reviewed by the Ethics Committee of South-East Sweden. The findings showed that mean scores of nursing students' moral sensitivity were found in the middle to upper segment of the rating scale. Multivariate analysis showed that gender (odds ratio = 3.32), age (odds ratio = 2.09; 1.73), and parental status (odds ratio = 0.31) were of relevance to nursing students' moral sensitivity. Academic year was found to be unrelated to moral sensitivity. These demographic aspects should be considered when designing ethics education for nursing students. Future studies should continue to investigate moral sensitivity in nursing students, such as if and how various pedagogical strategies in ethics may contribute to moral sensitivity in nursing students.

Dysgeusia is one of the sporadic adverse effects induced by chemotherapy, but it remains poorly understood. The aim of this study was to retrospectively identify the risk factors related with dysgeusia in patients undergoing autologous hematopoietic stem cell transplantation (AHSCT). Forty-eight patients with myeloma or lymphoma undergoing AHSCT were enrolled in this study. Data regarding dysgeusia and symptoms were collected by interviews conducted by medical workers. Patient characteristics and unfavorable effects induced by dysgeusia were obtained from medical records and analyzed. Logistic regression analysis was performed to identify the risk factors related with dysgeusia. Of the 48 patients, 20 (42 %) had dysgeusia after AHSCT. The total period of parenteral nutrition (TPN) administration and period of decreased oral intake in the dysgeusia group were statistically longer than those in the non-dysgeusia group. Multivariate analyses revealed that oral mucositis (odds ratio: 30.3; p < 0.01) and the type of chemotherapy prior to AHSCT (odds ratio: 6.56; p < 0.05) were independent risk factors, while oral cryotherapy was the independent suppressive factor of dysgeusia (odds ratio: 0.14; p < 0.05). Our study showed that dysgeusia after AHSCT led to the decrease in oral intake and extended the TPN administration period. Moreover, MEAM or LEED chemotherapy and oral mucositis were independent risk factors for dysgeusia in patients undergoing AHSCT, while oral cryotherapy was an independent suppressive factor for dysgeusia. Therefore, oral cryotherapy should be implemented into the regimen of supportive care management in patients undergoing AHSCT.

The primary aims of this study were to design prediction models based on a functional marker (preoperative gait speed) to predict readiness for home discharge time of 90 mins or less and to identify those at risk for unplanned admissions after elective ambulatory surgery. This prospective observational cohort study evaluated all patients scheduled for elective ambulatory surgery. Home discharge readiness and unplanned admissions were the primary outcomes. Independent variables included preoperative gait speed, heart rate, and total anesthesia time. The relationship between all predictors and each primary outcome was determined in separate multivariable logistic regression models. After adjustment for covariates, gait speed with adjusted odds ratio of 3.71 (95% confidence interval, 1.21-11.26), P = 0.02, was independently associated with early home discharge readiness of 90 mins or less. Importantly, gait speed dichotomized as greater or less than 1 m/sec predicted unplanned admissions, with odds ratio of 0.35 (95% confidence interval, 0.16-0.76, P = 0.008) for those with speeds 1 m/sec or greater in comparison with those with speeds less than 1 m/sec. In a separate model, history of cardiac surgery with adjusted odds ratio of 7.5 (95% confidence interval, 2.34-24.41; P = 0.001) was independently associated with unplanned admissions after elective ambulatory surgery, when other covariates were held constant. This study demonstrates the use of novel prediction models based on gait speed testing to predict early home discharge and to identify those patients at risk for unplanned admissions after elective ambulatory surgery.

Methods to examine whether genetic and/or environmental sources can account for the residual variation in ordinal family data usually assume proportional odds. However, standard software to fit the non-proportional odds model to ordinal family data is limited because the correlation structure of family data is more complex than for other types of clustered data. To perform these analyses we propose the non-proportional odds multivariate logistic regression model and take a simulation-based approach to model fitting using Markov chain Monte Carlo methods, such as partially collapsed Gibbs sampling and the Metropolis algorithm. We applied the proposed methodology to male pattern baldness data from the Victorian Family Heart Study. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The metabolism of high-fructose corn syrup used to sweeten soda drinks may lead to elevations in uric acid levels. Here we determined whether soda drinking is associated with hyperuricemia and, as a potential consequence, reduced kidney function. At baseline, 15,745 patients in the Atherosclerosis Risk in Communities Study completed a dietary questionnaire and had measurements of their serum creatinine and uric acid. After 3 and 9 years of follow-up, multivariate odds ratios from logistic regressions for binary outcome of hyperuricemia and chronic kidney disease (eGFR less than 60 ml/min per 1.73 m2) were evaluated. Compared to participants who drank less, consumption of over one soda per day was associated with increased odds of prevalent hyperuricemia and chronic kidney disease. The odds ratio for chronic kidney disease significantly increased to 2.59 among participants who drank more than one soda per day and had a serum uric acid level over 9.0 mg/dl. In longitudinal analyses, however, drinking more than one soda per day was not associated with hyperuricemia or chronic kidney disease. Neither preexistent hyperuricemia nor development of hyperuricemia modified the lack of association between soda drinking and incident chronic kidney disease. Thus our study shows that high consumption of sugar-sweetened soda was associated with prevalent but not incident hyperuricemia and chronic kidney disease. PMID:20032963

To better inform local management of TB-diabetes collaborative activities, we aimed to determine the prevalence of diabetes among persons with and without TB and to determine the association between TB and diabetes in Kiribati, a Pacific Island nation. We compared consecutively enrolled TB cases to a group of randomly selected community controls without evidence of TB. Diabetes was diagnosed by HbA1c, and clinical and demographic data were collected. A tuberculin skin test was administered to controls. The chi-square test was used to assess significance in differences between cases and controls. We also calculated an odds ratio, with 95% confidence intervals, for the odds of diabetes among cases relative to controls. Unweighted multivariate logistic regression was performed to adjust for the effects of age and sex. A total of 275 TB cases and 499 controls were enrolled. The diabetes prevalence in cases (101, 37%) was significantly greater than in controls (94, 19%) (adjusted odds ratio: 2.8; 95% CI 2.0-4.1). Fifty-five percent (108) of all diabetic diagnoses were new; this proportion was higher among controls (64.8%) than cases (46.5%). Five patients with TB were screened to detect one patient with diabetes. There is a strong association between TB and diabetes in Kiribati and bidirectional screening should be conducted in this setting. © 2015 John Wiley & Sons Ltd.

Preliminary evidence suggests that daytime sleepiness may predate clinical diagnosis of Parkinson disease. The authors examined daytime napping and nighttime sleeping durations, reported in 1996–1997 by 220,934 US NIH-AARP Diet and Health Study participants, in relation to Parkinson disease diagnoses at 3 clinical stages: established (cases diagnosed before 1995, n = 267), recent (1995–1999, n = 396), and prediagnostic (2000 and after, n = 770). Odds ratios and 95% confidence intervals were derived from multivariate logistic regression models. Longer daytime napping was associated with higher odds of Parkinson disease at all 3 clinical stages: the odds ratios comparing long nappers (>1 hour/day) with nonnappers were 3.9 (95% confidence interval: 2.8, 5.6) for established cases, 2.2 (95% confidence interval: 1.7, 3.0) for recent cases, and 1.5 (95% confidence interval: 1.2, 1.9) for prediagnostic cases. Further control for health status or nighttime sleeping duration attenuated the association for established cases but made little difference for recent or prediagnostic cases. In the nighttime sleeping analysis, a clear U-shaped association with Parkinson disease was observed for established cases; however, this association was attenuated markedly for recent cases and disappeared for prediagnostic cases. This study supports the notion that daytime sleepiness, but not nighttime sleeping duration, is one of the early nonmotor symptoms of Parkinson disease. PMID:21402730

Many U.S. Marines have experienced routine combat deployments during Operation Iraqi Freedom, which present numerous occupational hazards that may result in low back pain (LBP). The objective of this retrospective cohort study was to identify new-onset LBP among Marines following initial deployment to Operation Iraqi Freedom. Active duty Marines deployed to Iraq or Kuwait between 2005 and 2008 were identified from deployment records and linked to medical databases (n = 36,680). The outcome of interest was an International Classification of Diseases, 9th Revision, Clinical Modification code indicating LBP (724.2) within 1 year postdeployment. Multivariate logistic regression examined the effect of occupation on LBP. Overall, 4.1% (n = 1,517) of Marines were diagnosed with LBP. After adjusting for covariates, the service/supply (odds ratio 1.33, 95% confidence interval, 1.12-1.59) and electrical/mechanical/craftsworker occupations (odds ratio 1.31, 95% confidence interval, 1.12-1.53) had higher odds of LBP when compared to the administrative/other referent group. Within these groups, the highest LBP prevalence was in the construction (8.6%) and law enforcement (6.2%) subgroups. Although infantry occupations purposefully engage the enemy and often face sustained physical rigors of combat, LBP was most prevalent in noninfantry occupations. Future studies should include detailed exposure histories to elucidate occupation-specific etiologies of LBP in order to guide prevention efforts.

To determine predictors of untreated dental decay among 15-34-year-olds in Australia. Data were from Australia's National Survey of Adult Oral Health, a representative survey that utilized a three-stage, stratified clustered sampling design. Models representing demographic, socioeconomic, dental service utilization and oral health perception variables were tested using multivariable logistic regression to produce odds ratios. An estimated 25.8% (95% CI 22.4-29.5) of 15-34-year-old Australians had untreated dental decay. After controlling for other covariates, those who lived in a location other than a capital city had 2.0 times the odds of having untreated dental decay than their capital city-dwelling counterparts (95% CI 1.29-3.06). Similarly, those whose highest level of education was not a university degree had 2.1 times the odds of experiencing untreated dental decay (95% CI 1.35-3.31). Perceived need of extractions or restorations predicted untreated coronal decay, with 2.9 times the odds for those who perceived a treatment need over those with no such treatment need perception (95% CI 1.84-4.53). Participants who experienced dental fear had 2.2 times the odds of having untreated dental decay (95% CI 1.38-3.41), while those who reported experiencing toothache, orofacial pain or food avoidance in the last 12 months had 1.9 times the odds of having untreated dental decay than their counterparts with no such oral health-related quality-of-life impact (95% CI 1.20-2.92). The multivariate model achieved a 'useful' level of accuracy in predicting untreated decay (area under the ROC curve = 0.74; sensitivity = 0.63; specificity = 0.73). In the Australian young adult population, residential location, education level, perceived need for dental care, dental fear, toothache, orofacial pain or food avoidance together were predictors of untreated dental decay. The prediction model had acceptable specificity, indicating that it may be useful as part of a triage system for health departments wishing to screen by means of a questionnaire for apparently-dentally healthy 15-34-year-olds.

Older homeless-experienced adults have low engagement in advance care planning (ACP) despite high morbidity and mortality. We conducted a cross-sectional analysis of a cohort of 350 homeless-experienced adults aged 50 and older in Oakland, California. We assessed the prevalence of potential surrogate decision-makers, ACP contemplation, discussions, and ACP documentation (surrogate designation, advance directives). We used multivariable logistic regression to examine factors associated with ACP discussions and documentation. The median age of the cohort was 59 (range 52-82), 75.2% were male, and 82.1% were black. Sixty-one percent reported a potential surrogate, 21.5% had discussed ACP, and 19.0% reported ACP documentation. In multivariable models, having 1 to 5 confidants versus none (adjusted odds ratio (aOR)=5.8, 95% confidence interval (CI)=1.7-20.0), 3 or more chronic conditions versus none (aOR=2.3, 95% CI=0.9-5.6), and a recent primary care visit (aOR=2.1, 95% CI=1.0-4.4) were associated with higher odds of ACP discussions and each additional 5 years of homelessness (aOR=0.7, 95% CI=0.5-0.9) with lower odds. Having 1 to 5 confidants (aOR=5.0, 95% CI=1.4-17.5), being black (aOR=5.5, 95% CI=1.5-19.5), and having adequate versus limited literacy (aOR=7.0, 95% CI=1.5-32.4) were associated with higher odds of ACP documentation and illicit drug use (aOR=0.3, 95% CI=0.1-0.9) with lower odds. Although the majority of older homeless-experienced adults have a potential surrogate, few have discussed or documented their ACP wishes; the odds of both were greater with larger social networks. Future interventions must be customized for individuals with limited social networks and address the instability of homelessness, health literacy, and the constraints of safety-net healthcare settings. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

The purpose of this study was to determine the joint associations of sedentary time and physical activity with mobility disability in older age. We analyzed prospective data from 134,269 participants in the National Institutes of Health (NIH)-American Association of Retired Persons (NIH-AARP) Diet and Health Study between 1995-1996 and 2004-2005. Total sitting time (h/d), TV viewing time (h/d) and light- and moderate-to-vigorous-intensity physical activity (h/wk) were self-reported at baseline, and mobility disability at follow-up was defined as being "unable to walk" or having an "easy usual walking pace (<2 mph)." Multivariable logistic regression determined the independent and joint associations of sedentary time and total physical activity with the odds of disability. Among the most active participants (>7 h/wk), sitting <6 h/d was not related to excess disability at follow-up, and those in the most active group reporting the highest level of sitting time (≥7 h/d) still had a significantly lower odds (odds ratios = 1.11; 95% confidence interval = 1.02, 1.20) compared with those reporting the lowest level of sitting (<3 h/d) in the least active group (≤3 h/wk; odds ratios = 2.07; 95% confidence interval = 1.92, 2.23). Greater TV time was significantly related to increased disability within all levels of physical activity. Reduction of sedentary time, combined with increased physical activity may be necessary to maintain function in older age.

There is a growing concern that the historic reductions in tobacco consumption witnessed in the past decades may be undermined by the rapid increase in e-cigarette use. This study examined the association between e-cigarette use and future intention to smoke cigarettes among middle and high school students who had never smoked cigarettes. Data were drawn from the 2014-2015 Canadian Student Tobacco, Alcohol and Drugs Survey (n=25,637). A multivariable logistic regression model was used to examine the association between e-cigarette use and susceptibility to cigarette smoking. In addition, an inverse probability of treatment weighted regression adjustment method (doubly robust estimator), which models both the susceptibility to smoking and the probability of e-cigarette use, was conducted. About 10% of the students had ever tried an e-cigarette. There were higher rates of ever e-cigarette use among students in grades 10-12 (12.5%) than those in grades 7-9 (7.3%). Students who had ever tried an e-cigarette had higher odds of susceptibility to cigarette smoking (adjusted odds ratio=2.16, 95% confidence interval=1.80-2.58) compared to those that had never tried an e-cigarette. Current use of an e-cigarette was associated with higher odds of smoking susceptibility (adjusted odds ratio=2.02, 95% confidence interval=1.43-2.84). Similar results were obtained from the doubly robust estimation. Among students who had never smoked cigarettes, e-cigarette use was associated with a higher susceptibility to cigarette smoking.

Objective To determine whether there is an increased odds of mortality among trauma patients treated at hospitals with higher proportions of minority patients (ie, black and Hispanic patients combined). Design Hospitals were categorized on the basis of the percentage of minority patients admitted with trauma. The adjusted odds of in-hospital mortality were compared between hospitals with less than 25% of patients who were minorities (the reference group) and hospitals with 25% to 50% of patients who were minorities and hospitals with more than 50% of patients who were minorities. Multivariate logistic regression (with generalized linear modeling and a cluster-correlated robust estimate of variance) was used to control for multiple patient and injury severity characteristics. Setting A total of 434 hospitals in the National Trauma Data Bank. Participants Patients aged 18 to 64 years whose medical records were included in the National Trauma Data Bank for the years 2007 and 2008 with an Injury Severity Score of 9 or greater and who were white, black, or Hispanic. Main Outcome Measures Crude mortality and adjusted odds of in-hospital mortality. Results A total of 311 568 patients were examined. Hospitals in which the percentage of minority patients was more than 50% also had younger patients, fewer female patients, more patients with penetrating trauma, and the highest crude mortality. After adjustment for potential confounders, patients treated at hospitals in which the percentage of minority patients was 25% to 50% and at hospitals in which the percentage of minority patients was more than 50% demonstrated increased odds of death (adjusted odds ratio, 1.16 [95% confidence interval, 1.01–1.34] and adjusted odds ratio, 1.37 [95% confidence interval, 1.16–1.61], respectively), compared with the reference group. This disparity increased further on subset analysis of patients with a blunt injury. Uninsured patients had significantly increased odds of mortality within all 3 hospital groups. Conclusions Patients treated at hospitals with higher proportions of minority trauma patients have increased odds of dying, even after adjusting for potential confounders. Differences in outcomes between trauma hospitals may partly explain racial disparities. PMID:21930976

In 2004, 803 rural Iowans from the Agricultural Health Study were enrolled in a 2-year prospective study of zoonotic influenza transmission. Demographic and occupational exposure data from enrollment, 12-month, and 24-month follow-up encounters were examined for association with evidence of previous and incident influenza virus infections. When proportional odds modeling with multivariable adjustment was used, upon enrollment, swine-exposed participants (odds ratio [OR] 54.9, 95% confidence interval [CI] 13.0–232.6) and their nonswine-exposed spouses (OR 28.2, 95% CI 6.1–130.1) were found to have an increased odds of elevated antibody level to swine influenza (H1N1) virus compared with 79 nonexposed University of Iowa personnel. Further evidence of occupational swine influenza virus infections was observed through self-reported influenza-like illness data, comparisons of enrollment and follow-up serum samples, and the isolation of a reassortant swine influenza (H1N1) virus from an ill swine farmer. Study data suggest that swine workers and their nonswine-exposed spouses are at increased risk of zoonotic influenza virus infections. PMID:18258038

Association Between Vestibular Vertigo and Motor Vehicle Accidents: Data From the 2016 National Health Interview Survey.

Recent evidence has shown that individuals with vestibular impairment have higher rates of self-reported driving difficulty compared with individuals without vestibular impairment. However, it is unknown whether individuals with vestibular impairment are more likely to be involved in motor vehicle accidents. We used data from the 2016 National Health Interview Survey of U.S. adults to evaluate whether individuals with vestibular vertigo are more likely to experience motor vehicle accidents relative to individuals without vestibular vertigo. In multivariate analysis, vestibular vertigo was associated with an over threefold increased odds of motor vehicle accidents (odds ratio, 3.5; 95% confidence interval, 1.7-7.3). This study supports an assciation between vestibular dysfunction and driving impairment, and provides a relative risk of motor vehicle accidents associated with vestibular vertigo that clinicians may utilize in counseling patients on the potential safety hazards of driving.

Mental health and food insecurity are major public health issues among adolescents in Ecuador. Our objective was to determine the relationship between hunger, symptoms of depression, and suicidal ideation among school-going Ecuadorian adolescents. We conducted crude and multivariable logistic regression models using data from the 2007 Global School-based Student Health Survey from Quito, Guayaquil, and Zamora, Ecuador (N = 5524). Hunger was defined as having gone hungry in the past 30 days due to lack of food in the home. Outcomes of interest were symptoms of depression and suicidal ideation with or without planning in the past year. Overall, 41.2 % (2200/5467) of students reported experiencing hunger. In multivariable logistic regression models, hunger had an increasing exposure-response relationship with symptoms of depression [sometimes hungry odds ratio (OR) 1.80, P = 0.0001; most of the time or always hungry OR 2.01, P < 0.0001] and suicidal ideation with planning (sometimes hungry OR 1.55, P = 0.04; most of the time or always hungry OR 2.63, P = 0.001). Hunger was associated with increased odds of symptoms of depression and suicidal ideation with planning. Strategies to improve mental health among adolescents in Ecuador should consider the potential contribution of hunger and food insecurity.

Nonheterosexual adolescents are vulnerable to health risks including addiction, bullying, and familial abuse. We examined whether they also suffer disproportionate school and criminal-justice sanctions. The National Longitudinal Study of Adolescent Health followed a nationally representative sample of adolescents who were in grades 7 through 12 in 1994-1995. Data from the 1994-1995 survey and the 2001-2002 follow-up were analyzed. Three measures were used to assess nonheterosexuality: same-sex attraction, same-sex romantic relationships, and lesbian, gay, or bisexual (LGB) self-identification. Six outcomes were assessed: school expulsion; police stops; juvenile arrest; juvenile conviction; adult arrest; and adult conviction. Multivariate analyses controlled for adolescents' sociodemographics and behaviors, including illegal conduct. Nonheterosexuality consistently predicted a higher risk for sanctions. For example, in multivariate analyses, nonheterosexual adolescents had greater odds of being stopped by the police (odds ratio: 1.38 [P < .0001] for same-sex attraction and 1.53 [P < .0001] for LGB self-identification). Similar trends were observed for school expulsion, juvenile arrest and conviction, and adult conviction. Nonheterosexual girls were at particularly high risk. Nonheterosexual youth suffer disproportionate educational and criminal-justice punishments that are not explained by greater engagement in illegal or transgressive behaviors. Understanding and addressing these disparities might reduce school expulsions, arrests, and incarceration and their dire social and health consequences.

Objectives. We examined individual, friend or family, and community or tribe correlates of suicidality in a representative on-reserve sample of First Nations adolescents. Methods. Data came from the 2002–2003 Manitoba First Nations Regional Longitudinal Health Survey of Youth. Interviews were conducted with adolescents aged 12 to 17 years (n = 1125) from 23 First Nations communities in Manitoba. We used bivariate logistic regression analyses to examine the relationships between a range of factors and lifetime suicidality. We conducted sex-by-correlate interactions for each significant correlate at the bivariate level. A multivariate logistic regression analysis identified those correlates most strongly related to suicidality. Results. We found several variables to be associated with an increased likelihood of suicidality in the multivariate model, including being female, depressed mood, abuse or fear of abuse, a hospital stay, and substance use (adjusted odds ratio range = 2.43–11.73). Perceived community caring was protective against suicidality (adjusted odds ratio = 0.93; 95% confidence interval = 0.88, 0.97) in the same model. Conclusions. Results of this study may be important in informing First Nations and government policy related to the implementation of suicide prevention strategies in First Nations communities. PMID:22676500

A high fructose intake has been shown to be associated with increased serum urate concentration, whereas ascorbate (vitamin C) may lower serum urate by competing with urate for renal reabsorption. We assessed the combined association, as the fructose:vitamin C intake ratio, and the separate associations of dietary fructose and vitamin C intakes on prevalent hyperuricemia. We conducted cross-sectional analyses of dietary intakes of fructose and vitamin C and serum urate concentrations among Jackson Heart Study participants, a cohort of African Americans in Jackson, Mississippi, aged 21-91 y. In the analytic sample (n = 4576), multivariable logistic regression was used to examine the separate associations of dietary intakes of fructose and vitamin C and the fructose:vitamin C intake ratio with prevalent hyperuricemia (serum urate ≥7 mg/dL), after adjusting for age, sex, smoking, waist circumference, systolic blood pressure, estimated glomerular filtration rate, diuretic medication use, vitamin C supplement use, total energy intake, alcohol consumption, and dietary intake of animal protein. Analyses for individual dietary factors (vitamin C, fructose) were adjusted for the other dietary factor. In the fully adjusted model, there were 17% greater odds of hyperuricemia associated with a doubling of the fructose:vitamin C intake ratio (OR: 1.17; 95% CI: 1.08, 1.28), 20% greater odds associated with a doubling of fructose intake (OR: 1.20; 95% CI: 1.08, 1.34), and 13% lower odds associated with a doubling of vitamin C intake (OR: 0.87; 95% CI: 0.78, 0.97). Dietary fructose and the fructose:vitamin C intake ratio were more strongly associated with hyperuricemia among men than women (P-interaction ≤ 0.04). Dietary intakes of fructose and vitamin C are associated with prevalent hyperuricemia in a community-based population of African Americans.

Background : Environmental and policy factors can influence weight status via facilitating or discouraging physical activity and healthy diet. Despite mixed evidence, some findings suggest that the neighborhood built environment, including “walkability”, is associated with overweight and obesity. Most of these findings have measured body mass index (BMI), yet other weight status measures including waist circumference (WC) and waist-to-hip (W-H) ratio are also predictive of health outcomes, independent of BMI. Our study aim was to estimate the associations between walkability, measured using Walk Score ® , and each of WC, W-H ratio, and BMI among urban Canadian adults. Methods : In 2014, n = 851 adults recruited from 12 structurally and socioeconomic diverse neighborhoods (Calgary, Alberta, Canada) provided complete data on a physical activity, health and demographic questionnaire and self-reported anthropometric measures (i.e., height and weight, WC and hip circumference). Anthropometric data were used to estimate WC, W-H ratio, and BMI which were categorized into low and high risk in relation to their potential adverse effect on health. WC and BMI were also combined to provide a proxy measure of both overall and abdominal adiposity. Multivariable logistic regression models estimated odds ratios (OR) and 95% confidence intervals (CI) for associations between each weight status outcome and Walk Score ® . Results : A one-unit increase in Walk Score ® was associated with lower odds of being high-risk based on WC (OR = 0.99; 95%CI 0.97⁻0.99). Notably, those residing in socioeconomically disadvantage neighborhoods had significantly higher odds of being high risk based on WC, BMI, and WC-BMI combined compared with advantaged neighborhoods. Conclusions : Interventions that promote healthy weight through the design of neighborhoods that support and enhance the effect of physical activity and diet-related interventions could have a significant population health impact.

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.

To determine whether injection augmentation reduces the likelihood of ultimately needing definitive framework surgery in unilateral vocal fold paralysis (UVFP) patients. Retrospective cohort study. All patients diagnosed with UVFP (2008-2012) at the academic center were identified. The time from symptom onset to presentation to either community otolaryngologist and/or academic center, as well as any directed treatment(s), were recorded. Stepwise, multivariate logistic regression analysis was used to determine whether injection augmentation independently affected odds of needing definitive, framework surgery among patients who were seen within 9 months of symptom onset and had not undergone any prior rehabilitative procedures. Cohort consisted of 633 patients (55% female, 80% Caucasian, median age 60 years) with UVFP. The majority of etiologies were either surgery (48%) or idiopathic (37%). Duration to presentation at community otolaryngologist was shorter than to the academic center (median 2 vs. 6 months). Overall, less than half of UVFP patients had any operation (46%). Multivariate logistic regression found that earlier injection augmentation did not affect odds of ultimately undergoing framework surgery (odds ratio 1.13; confidence interval, 0.92-1.40; P = 0.23). Nearly half of UVFP patients do not require any rehabilitative procedure. When indicated, early injection augmentation is effective at temporarily alleviating associated symptoms but does not reduce likelihood of needing a definitive framework operation in patients with UVFP. Understanding practice patterns and fostering early detection and treatment may improve quality of life in this patient population. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

In a prospective trial 266 multiple injured patients were included to evaluate clinical risk factors and immune parameters related to pneumonia. Clinical and humoral parameters were assessed and multivariate analysis performed. The multivariate analysis (odds ratio with 95% confidence interval (CI)) revealed male gender (3.65), traumatic brain injury (TBI) (2.52), thorax trauma (AIS(thorax) > or = 3) (2.05), antibiotic prophylaxis (1.30), injury severity score (ISS) (1.03 per ISS point) and the age (1.02 per year) as risk factors for pneumonia. The main pathogens were Acinetobacter Baumannii (40%) and Staphylococcus aureus (25%). A tendency towards higher Procalcitonin (PCT) and Interleukin (IL)-6 levels two days after trauma was observed for pneumonia patients. The immune parameters (PCT, IL-6, IL-10, soluble tumor necrosis factor p-55 and p-75) could not confirm the diagnosis of pneumonia earlier than the clinical parameters.

General aviation (GA) accidents have continued to demonstrate high fatality rates. Recently, ballistic parachute recovery systems (BPRS) have been introduced as a safety feature in some GA aircraft. This study evaluates the effectiveness and associated factors of the Cirrus Airframe Parachute System (CAPS) at reducing the odds of a fatal accident in Cirrus aircraft crashes. Publicly available Cirrus aircraft crash reports were obtained from the National Transportation Safety Board (NTSB) database for the period of January 1, 2001-December 31, 2016. Accident metrics were evaluated through univariate and multivariate analyses regarding odds of a fatal accident and use of the parachute system. Included in the study were 268 accidents. For CAPS nondeployed accidents, 82 of 211 (38.9%) were fatal as compared to 8 of 57 (14.0%) for CAPS deployed accidents. After controlling for all other factors, the adjusted odds ratio for a fatal accident when CAPS was not deployed was 13.1. The substantial increased odds of a fatal accident when CAPS was not deployed demonstrated the effectiveness of CAPS at providing protection of occupants during an accident. Injuries were shifted from fatal to serious or minor with the use of CAPS and postcrash fires were significantly reduced. These results suggest that BPRS could play a significant role in the next major advance in improving GA accident survival.Alaziz M, Stolfi A, Olson DM.

The aim of this study was to evaluate the associations between educational level and cardiovascular disease (CVD) in an older Iranian population. To estimate the odds ratio (OR) of educational level in a cross-sectional study, logistic regression analysis was used on 1,788 men and 2,204 women (222 men and 204 women positive based on their CVD status) aged ≥ 45 years. In men, educational levels of college degree and literacy level below diploma were inversely associated with CVD in the multivariate model [0.52 (0.28-0.94), 0.61 (0.40-0.92), respectively], but diploma level did not show any significant association with CVD, neither in the crude model nor in the multivariate model. In women, increase in educational level was inversely associated with risk of CVD in the crude model, but in the multivariate adjusted model, literacy level below diploma decreased risk of CVD by 39%, compared with illiteracy. Our findings support those of developed countries that, along with other CVD risk factors, educational status has an inverse association with CVD among a representative Iranian population of older men and women.

To evaluate incidence, risk factors, and in-hospital outcomes associated with hyponatremia in patients hospitalized for Guillain-Barré Syndrome (GBS). We identified adult patients with GBS in the Nationwide Inpatient Sample (2002-2011). Univariate and multivariable analyses were used. Among 54,778 patients hospitalized for GBS, the incidence of hyponatremia was 11.8% (compared with 4.0% in non-GBS patients) and increased from 6.9% in 2002 to 13.5% in 2011 (P < 0.0001). Risk factors associated with hyponatremia in multivariable analysis included advanced age, deficiency anemia, alcohol abuse, hypertension, and intravenous immunoglobulin (all P < 0.0001). Hyponatremia was associated with prolonged length of stay (16.07 vs. 10.41, days), increased costs (54,001 vs. 34,125, $USD), and mortality (20.5% vs. 11.6%) (all P < 0.0001). In multivariable analysis, hyponatremia was independently associated with adverse discharge disposition (odds ratio: 2.07, 95% confidence interval, 1.91-2.25, P < 0.0001). Hyponatremia is prevalent in GBS and is detrimental to patient-centered outcomes and health care costs. Sodium levels should be carefully monitored in high-risk patients.

Objectives. We determined cigarette smoking prevalence, desire to quit, and tobacco-related counseling among a national sample of patients at health centers. Methods. Data came from the 2009 Health Center Patient Survey and the 2009 National Health Interview Survey. The analytic sample included 3949 adult patients at health centers and 27 731 US adults. Results. Thirty-one percent of health center patients were current smokers, compared with 21% of US adults in general. Among currently smoking health center patients, 83% desired to quit and 68% received tobacco counseling. In multivariable models, patients had higher adjusted odds of wanting to quit if they had indications of severe mental illness (adjusted odds ratio [AOR] = 3.26; 95% confidence interval [CI] = 1.19, 8.97) and lower odds if they had health insurance (AOR = 0.43; 95% CI = 0.22, 0.86). Patients had higher odds of receiving counseling if they had 2 or more chronic conditions (AOR = 2.05; 95% CI = 1.11, 3.78) and lower odds if they were Hispanic (AOR = 0.57; 95% CI = 0.34, 0.96). Conclusions. Cigarette smoking prevalence is substantially higher among patients at health centers than US adults in general. However, most smokers at health centers desire to quit. Continued efforts are warranted to reduce tobacco use in this vulnerable group. PMID:24625147

In multivariable models, patients had higher adjusted odds of wanting to quit if they had indications of severe mental illness (adjusted odds ratio [AOR] = 3.26; 95% confidence interval [CI] = 1.19, 8.97) and lower odds if they had health insurance (AOR = 0.43; 95% CI = 0.22, 0.86). Patients had higher odds of receiving counseling if they had 2 or more chronic conditions (AOR = 2.05; 95% CI = 1.11, 3.78) and lower odds if they were Hispanic (AOR = 0.57; 95% CI = 0.34, 0.96). Conclusions. Cigarette smoking prevalence is substantially higher among patients at health centers than US adults in general. However, most smokers at health centers desire to quit. Continued efforts are warranted to reduce tobacco use in this vulnerable group.

Objectives. We examined associations between parental military service and adolescent well-being. Methods. We used cross-sectional data from the 2008 Washington State Healthy Youth Survey collected in public school grades 8, 10, and 12 (n = 10 606). We conducted multivariable logistic regression analyses to test associations between parental military service and adolescent well-being (quality of life, depressed mood, thoughts of suicide). Results. In 8th grade, parental deployment was associated with higher odds of reporting thoughts of suicide among adolescent girls (odds ratio [OR] = 1.66; 95% confidence interval [CI] = 1.19, 2.32) and higher odds of low quality of life (OR = 2.10; 95% CI = 1.43, 3.10) and thoughts of suicide (OR = 1.75; 95% CI = 1.15, 2.67) among adolescent boys. In 10th and 12th grades, parental deployment was associated with higher odds of reporting low quality of life (OR = 2.74; 95% CI = 1.79, 4.20), depressed mood (OR = 1.50; 95% CI = 1.02, 2.20), and thoughts of suicide (OR = 1.64; 95% CI = 1.13, 2.38) among adolescent boys. Conclusions. Parental military deployment is associated with increased odds of impaired well-being among adolescents, especially adolescent boys. Military, school-based, and public health professionals have a unique opportunity to develop school- and community-based interventions to improve the well-being of adolescents in military families.

To determine the association between prophylactic plasma transfusion and periprocedural red blood cell (RBC) transfusion rates in patients with elevated international normalized ratio (INR) values undergoing interventional radiology procedures. In this retrospective cohort study, adult patients undergoing interventional radiology procedures with a preprocedural INR available within 30 days of the procedure during a study period of January 1, 2009, to December 31, 2013, were eligible for inclusion. Baseline characteristics, coagulation parameters, transfusion requirements, and procedural details were extracted. Univariate and multivariable propensity-matched analyses were used to assess the relationships between prophylactic plasma transfusion and the outcomes of interest, with a primary outcome assessed a priori of RBC transfusion occurring during the procedure or within the first 24 hours postprocedurally. A total of 18,204 study participants met inclusion criteria for this study, and 1803 (9.9%) had an INR of 1.5 or greater before their procedure. Of these 1803 patients, 196 patients (10.9%) received prophylactic plasma transfusion with a median time of 1.9 hours (interquartile range [IQR], 1.1-3.2 hours) between plasma transfusion initiation and procedure initiation. In multivariable propensity-matched analysis, plasma administration was associated with increased periprocedural RBC transfusions (odds ratio, 2.20; 95% CI, 1.38-3.50; P<.001) and postprocedural intensive care unit admission rates (odds ratio, 2.11; 95% CI, 1.41-3.14; P<.001) as compared with those who were not transfused preprocedurally. Similar relationships were seen at higher INR thresholds for plasma transfusion. In patients undergoing interventional radiology procedures, preprocedural plasma transfusions given in the setting of elevated INR values were associated with increased periprocedural RBC transfusions. Additional research is needed to clarify this potential association between preprocedural plasma transfusion and periprocedural RBC transfusion.

There is clinical equipoise regarding post-operative management of patients with patent ductus arteriosus (PDA) without insertion of a chest drain. This study evaluated post operative outcomes of chest closure with or without a drain following Patent Ductus Arteriosus ligation among childen at Uganda Heart Instritute (UHI). This was an open label randomized controlled trial of 62 children 12 years of age and below diagnosed with patent ductus arteriosus at Mulago National Teaching and Referral Hospital, Uganda. Participants were randomized in the ratio of 1:1 with surgical ligation of patent ductus arteriosus to either thoracotomy closure with a chest tube or without a chest tube. All participants received standard care and were monitored hourly for 24 hours then until hospital discharge. The combined primary endpoint consisted of significant pleural space accumulation of fluid or air, higher oxygen need or infection of the surgical site. Analysis was conducted by multivariable logistic regression analysis at 5 % significance level. We enrolled 62 participants, 46 (74 %) of whom were females. Their median age was 12 months (IQR: 8-36). Participants in the no-drain arm significantly had less post-operative complications compared to the drain arm (Unadjusted odds ratio [uOR]: 0.21, 95 % CI: 0.06-0.73, p = 0.015). This "protective effect" remained without statistical significance in the multivariable regression model (Adjusted odds ratio [aOR]: 0.07, 95 % CI: 0.00-2.50, p = 0.144). Children aged below 6 years with patent ductus arterious can safely and effectively have thoracotomy closure without using a drain in uncomplicated surgical ligation of the PDA. Chest drain was associated with post-operative complications. The trial was registered in the Pan African Clinical Trials registry on 1st/July/2012, retrospectively registered.

The metabolic syndrome (MetS) might confer a higher resistance to intravenous thrombolysis in acute middle cerebral artery (MCA) ischemic stroke. MetS increases the risk of stroke in women to a greater extent than in men. We aimed to investigate whether there might be sex differences in the impact of MetS on the response to intravenous thrombolysis for acute MCA ischemic stroke. We prospectively studied consecutive ischemic stroke patients, treated with intravenous tissue-type plasminogen activator according to SITS-MOST criteria, with an MCA occlusion on prebolus transcranial Doppler examination. Resistance to thrombolysis was defined as the absence of complete MCA recanalization 24 hours after tissue-type plasminogen activator infusion by transcranial Doppler criteria. MetS was diagnosed according to the criteria established by the American Heart Association/National Heart, Lung, and Blood Institute 2005 statement. A total of 125 patients (75 men, 50 women; mean age, 67.6+/-11 years) were included. MetS was diagnosed in 76 (61%) patients. Resistance to clot lysis at 24 hours was observed in 53 (42%) patients. Two multivariate-adjusted, logistic-regression models identified that MetS was associated with a higher resistance to tissue-type plasminogen activator, independently of other significant baseline variables (odds ratio=9.8; 95% CI, 3.5 to 27.8; P=0.0001) and of the individual components of the MetS. The MetS was associated with a significantly higher odds of resistance to thrombolysis in women (odds ratio=17.5; 95% CI, 1.9 to 163.1) than in men (odds ratio=5.1; 95% CI, 1.6 to 15.6; P for interaction=0.0004). The effect of MetS on the resistance to intravenous thrombolysis for acute MCA ischemic stroke appears to be more pronounced in women than in men.

With the development and widespread use of combination antiretroviral therapy, HIV-infected women live longer, healthier lives. Previous research has shown that, since the adoption of combination antiretroviral therapy in the United States, rates of morbidity and adverse obstetric outcomes remained higher for HIV-infected pregnant women compared with HIV-uninfected pregnant women. Monitoring trends in the outcomes these women experience is essential, as recommendations for this special population continue to evolve with the progress of HIV treatment and prevention options. We conducted an analysis comparing rates of hospitalizations and associated outcomes among HIV-infected and HIV-uninfected pregnant women in the United States from 2004 through 2011. We used cross-sectional hospital discharge data for girls and women age 15-49 from the 2004, 2007, and 2011 Nationwide Inpatient Sample, a nationally representative sample of US hospital discharges. Demographic characteristics, morbidity outcomes, and time trends were compared using χ(2) tests and multivariate logistic regression. Analyses were weighted to produce national estimates. In 2011, there were 4751 estimated pregnancy hospitalizations and 3855 delivery hospitalizations for HIV-infected pregnant women; neither increased since 2004. Compared with those of HIV-uninfected women, pregnancy hospitalizations of HIV-infected women were more likely to be longer, be in the South and Northeast, be covered by public insurance, and incur higher charges (all P < .005). Hospitalizations among pregnant women with HIV infection had higher rates for many adverse outcomes. Compared to 2004, hospitalizations of HIV-infected pregnant women in 2011 had higher odds of gestational diabetes (adjusted odds ratio, 1.81; 95% confidence interval, 1.16-2.84), preeclampsia/hypertensive disorders of pregnancy (adjusted odds ratio, 1.58; 95% confidence interval, 1.12-2.24), viral/mycotic/parasitic infections (adjusted odds ratio, 1.90; 95% confidence interval, 1.69-2.14), and bacterial infections (adjusted odds ratio, 2.54; 95% confidence interval, 1.53-4.20). Bacterial infections did not increase among hospitalizations of HIV-uninfected pregnant women. The numbers of hospitalizations during pregnancy and delivery have not increased for HIV-infected women since 2004, a departure from previously estimated trends. Pregnancy hospitalizations of HIV-infected women remain more medically complex than those of HIV-uninfected women. An increasing trend in infections among the delivery hospitalizations of HIV-infected pregnant women warrant further attention. Published by Elsevier Inc.

Although adjuvant endocrine therapy confers a survival benefit among females with hormone receptor (HR)-positive breast cancer, the effectiveness of this treatment among males with HR-positive breast cancer has not been rigorously investigated. To investigate trends, patterns of use, and effectiveness of adjuvant endocrine therapy among men with HR-positive breast cancer. This retrospective cohort study identified patients in the National Cancer Database with breast cancer who had received treatment from 2004 through 2014. Inclusion criteria for the primary study cohort were males at least 18 years old with nonmetastatic HR-positive invasive breast cancer who underwent surgery with or without adjuvant endocrine therapy. A cohort of female patients was also identified using the same inclusion criteria for comparative analyses by sex. Data analysis was conducted from October 1, 2017, to December 15, 2017. Receipt of adjuvant endocrine therapy. Patterns of adjuvant endocrine therapy use were assessed using multivariable logistic regression analyses. Association between adjuvant endocrine therapy use and overall survival was assessed using propensity score-weighted multivariable Cox regression models. The primary study cohort comprised 10 173 men with HR-positive breast cancer (mean [interquartile range] age, 66 [57-75] years). The comparative cohort comprised 961 676 women with HR-positive breast cancer (mean [interquartile range] age, 62 [52-72] years). The median follow-up for the male cohort was 49.6 months (range, 0.1-142.5 months). Men presented more frequently than women with HR-positive disease (94.0% vs 84.3%, P < .001). However, eligible men were less likely than women to receive adjuvant endocrine therapy (67.3% vs 79.0%; OR, 0.61; 95% CI, 0.58-0.63; P < .001). Treatment at academic facilities (odds ratio, 1.13; 95% CI, 1.02-1.25; P = .02) and receipt of adjuvant radiotherapy (odds ratio, 2.83; 95% CI, 2.55-3.15; P < .001) or chemotherapy (odds ratio, 1.20; 95% CI, 1.07-1.34; P < .001) were statistically significantly associated with adjuvant endocrine therapy use in men. A propensity score-weighted analysis indicated that relative to no use, adjuvant endocrine therapy use in men was associated with improved overall survival (hazard ratio, 0.70; 95% CI, 0.63-0.77; P < .001). There is a sex disparate underuse of adjuvant endocrine therapy among men with HR-positive breast cancer despite the use of this treatment being associated with improved overall survival. Further research and interventions may be warranted to bridge gaps in care in this population.

Objectives To assess the relationships between the risk factors and the incidence of nonfatal occupational injury of coal mine workers of Shanxi Province. Methods A cross-sectional study was conducted from July 2013 to December 2013, and 4319 workers were recruited from more than 200,000 coal mine employees who are exposed to continuous potential risk of occupational injuries by using a two-stage stratified cluster sampling method. Trained interviewers having necessary medical knowledge conducted face-to-face interviews with the participants. Univariate and multivariable logistic regression models were used to estimate the odds ratio (OR) and the 95% confidence interval (CI). Results A total number of 3618 effective respondents were got from 4319 participants (83.77%) and the mean age of the participants was 41.5 years with the standard deviation of 8.65. Significant crude odds ratios were observed for all factors considered except for marital status, education, work duration, BMI, EPQ-RSC(P) scale and EPQ-RSC(L) scale. Results from multivariable logistic regression model showed significant adjusted odds ratios for risk factors including gender (female vs male 0.275, 0.094–0.800), age (≥55 vs ≤25yr 0.169, 0.032–0.900), work type (light physical labor vs heavy physical labor 0.504, 0.328–0.774), workplace (underground auxiliary vs underground front-line 0.595, 0.385–0.919), length of shiftwork experience (0~5yr vs no shift 2.075, 1.287–3.344 and ≥15yr vs no shift 2.076, 1.230–3.504) and EPQ-RSC(E) score (extraversion vs introversion 0.538, 0.334–0.867). Conclusions Several risk factors of nonfatal occupational injury were identified including male, age, heavy physical labor, underground front-line, length of shiftwork experience and introversion. The coal mining enterprises should pay attention to controlling the hazards associated with frontline physical work. Workers’ behaviors, life styles and personality traits should also be considered, so that the enterprises could set achievable targets for workers and lessen the exposed period to the risky underground workstation.

Is there a role of whole-body bone scan in patients with esophageal squamous cell carcinoma

PubMed Central

2012-01-01

Background Correct detection of bone metastases in patients with esophageal squamous cell carcinoma is pivotal for prognosis and selection of an appropriate treatment regimen. Whole-body bone scan for staging is not routinely recommended in patients with esophageal squamous cell carcinoma. The aim of this study was to investigate the role of bone scan in detecting bone metastases in patients with esophageal squamous cell carcinoma. Methods We retrospectively evaluated the radiographic and scintigraphic images of 360 esophageal squamous cell carcinoma patients between 1999 and 2008. Of these 360 patients, 288 patients received bone scan during pretreatment staging, and sensitivity, specificity, positive predictive value, and negative predictive value of bone scan were determined. Of these 360 patients, surgery was performed in 161 patients including 119 patients with preoperative bone scan and 42 patients without preoperative bone scan. Among these 161 patients receiving surgery, 133 patients had stages II + III disease, including 99 patients with preoperative bone scan and 34 patients without preoperative bone scan. Bone recurrence-free survival and overall survival were compared in all 161 patients and 133 stages II + III patients, respectively. Results The diagnostic performance for bone metastasis was as follows: sensitivity, 80%; specificity, 90.1%; positive predictive value, 43.5%; and negative predictive value, 97.9%. In all 161 patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival (P = 0.009, univariately). In multivariate comparison, absence of preoperative bone scan (P = 0.012, odds ratio: 5.053) represented the independent adverse prognosticator for bone recurrence-free survival. In 133 stages II + III patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival (P = 0.003, univariately) and overall survival (P = 0.037, univariately). In multivariate comparison, absence of preoperative bone scan was independently associated with inferior bone recurrence-free survival (P = 0.009, odds ratio: 5.832) and overall survival (P = 0.029, odds ratio: 1.603). Conclusions Absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival, suggesting that whole-body bone scan should be performed before esophagectomy in patients with esophageal squamous cell carcinoma, especially in patients with advanced stages.

IMPORTANCE Reduced death and neurodevelopmental impairment among infants is a goal of perinatal medicine. OBJECTIVE To assess the association between surgery during the initial hospitalization and death or neurodevelopmental impairment of very low birth weight infants. DESIGN Retrospective cohort analysis of patients enrolled in the National Institute of Child Health and Human Development Neonatal Research Network Generic Database from 1998–2009 and evaluated at 18–22 months’ corrected age. SETTING 22 academic neonatal intensive care units. PARTICIPANTS Inclusion criteria were: birth weight 401–1500 g; survival to 12 hours; available for follow-up. Some conditions were excluded. 12 111 infants were included in analyses, 87% of those eligible. EXPOSURES Surgical procedures; surgery also classified by expected anesthesia type as major (general anesthesia) or minor surgery (non-general anesthesia). MAIN OUTCOME MEASURES Multivariable logistic regression analyses planned a priori were performed for the primary outcome of death or neurodevelopmental impairment and for the secondary outcome of neurodevelopmental impairment among survivors. Multivariable linear regression analyses were performed as planned for the adjusted means of Bayley Scales of Infant Development, Second Edition, Mental Developmental Index and Psychomotor Developmental Index for patients born before 2006. RESULTS There were 2186 major, 784 minor and 9141 no surgery patients. The risk-adjusted odds ratio of death or neurodevelopmental impairment for all surgery patients compared with those who had no surgery was 1.29 (95% confidence interval 1.08–1.55). For patients who had major surgery compared with those who had no surgery the risk-adjusted odds ratio of death or neurodevelopmental impairment was 1.52 (95% confidence interval 1.24–1.87). Patients classified as having minor surgery had no increased adjusted risk. Among survivors who had major surgery compared with those who had no surgery the adjusted odds ratio for neurodevelopmental impairment was 1.56 (95% confidence interval 1.26–1.93) and the adjusted mean Mental Developmental Index and mean Psychomotor Developmental Index values were lower. CONCLUSIONS AND RELEVANCE Major surgery in very low birth weight infants is independently associated with a greater than 50% increased risk of death or neurodevelopmental impairment and of neurodevelopmental impairment at 18–22 months’ corrected age. The role of general anesthesia is implicated but remains unproven. PMID:24934607

We performed an exome-wide association study (EWAS) to identify genetic variants - in particular, low-frequency or rare variants with a moderate to large effect size - that confer susceptibility to aortic aneurysm with 8,782 Japanese subjects (456 patients with aortic aneurysm, 8,326 control individuals) and with the use of Illumina HumanExome-12 DNA Analysis BeadChip or Infinium Exome-24 BeadChip arrays. The correlation of allele frequencies for 41,432 single nucleotide polymorphisms (SNPs) that passed quality control to aortic aneurysm was examined with Fisher's exact test. Based on Bonferroni's correction, a P-value of <1.21×10−6 was considered statistically significant. The EWAS revealed 59 SNPs that were significantly associated with aortic aneurysm. None of these SNPs was significantly (P<2.12×10−4) associated with aortic aneurysm by multivariable logistic regression analysis with adjustment for age, gender and hypertension, although 8 SNPs were related (P<0.05) to this condition. Examination of the correlation of these latter 8 SNPs to true or dissecting aortic aneurysm separately showed that rs1465567 [T/C (W229R)] of the EGF-like, fibronectin type III, and laminin G domains gene (EGFLAM) (dominant model; P=0.0014; odds ratio, 1.63) was significantly (P<0.0016) associated with true aortic aneurysm. We next performed EWASs for true or dissecting aortic aneurysm separately and found that 45 and 19 SNPs were significantly associated with these conditions, respectively. Multivariable logistic regression analysis with adjustment for covariates revealed that rs113710653 [C/T (E231K)] of the spermatogenesis- and centriole associated 1-like gene (SPATC1L) (dominant model; P=0.0002; odds ratio, 5.32) and rs143881017 [C/T (R140H)] of the ribonuclease A family member 13 gene (RNASE13) (dominant model; P=0.0006; odds ratio, 5.77) were significantly (P<2.78×10−4 or P<6.58×10−4, respectively) associated with true or dissecting aortic aneurysm, respectively. EGFLAM and SPATC1L may thus be susceptibility loci for true aortic aneurysm and RNASE13 may be such a locus for dissecting aneurysm in Japanese individuals. PMID:28339009

Hyperchloremia is associated with poor outcome among critically ill adults, but it is unknown if a similar association exists among critically ill children. We determined if hyperchloremia is associated with poor outcomes in children with septic shock. Retrospective analysis of a pediatric septic shock database. Twenty-nine PICUs in the United States. Eight hundred ninety children 10 years and younger with septic shock. None. We considered the minimum, maximum, and mean chloride values during the initial 7 days of septic shock for each study subject as separate hyperchloremia variables. Within each category, we considered hyperchloremia as a dichotomous variable defined as a serum concentration greater than or equal to 110 mmol/L. We used multivariable logistic regression to determine the association between the hyperchloremia variables and outcome, adjusted for illness severity. We considered all cause 28-day mortality and complicated course as the primary outcome variables. Complicated course was defined as mortality by 28 days or persistence of greater than or equal to two organ failures at day 7 of septic shock. Secondarily, we conducted a stratified analysis using a biomarker-based mortality risk stratification tool. There were 226 patients (25%) with a complicated course and 93 mortalities (10%). Seventy patients had a minimum chloride greater than or equal to 110 mmol/L, 179 had a mean chloride greater than or equal to 110 mmol/L, and 514 had a maximum chloride greater than or equal to 110 mmol/L. A minimum chloride greater than or equal to 110 mmol/L was associated with increased odds of complicated course (odds ratio, 1.9; 95% CI, 1.1-3.2; p = 0.023) and mortality (odds ratio, 3.7; 95% CI, 2.0-6.8; p < 0.001). A mean chloride greater than or equal to 110 mmol/L was also associated with increased odds of mortality (odds ratio, 2.1; 95% CI, 1.3-3.5; p = 0.002). The secondary analysis yielded similar results. Hyperchloremia is independently associated with poor outcomes among children with septic shock.

Association of smokeless tobacco use and smoking in adolescents in the US: Youth Risk Behavior Survey, 2011

Wiener, R. Constance

2014-01-01

Background Using smokeless tobacco and smoking are risk behaviors for oral cancer, soft tissue lesions, caries, periodontal disease and other oral conditions. The purpose of this study was to examine adolescent smokeless tobacco use and smoking. Methods The study was a cross-sectional analysis of participants with complete data on smoking, smokeless tobacco use, and other variables of interest in the 2011 Youth Risk Behavior Survey (n=9655). Descriptive analysis and multivariable logistic regression analyses were performed. Results The unadjusted odds ratio for smokeless tobacco use and smoking was 9.68 (95% CI: 7.72, 12.13, p<.0001); the adjusted odds ratio was 3.92 (95%CI: 2.89, 5.31, p<.0001). Adolescents using smokeless tobacco were more likely to be male, to smoke, and to have engaged in binge drinking. Conclusions Adolescents who are using smokeless tobacco are more likely to also be engaging in concomitant smoking and are participating in other risk-taking behaviors. Practice implications Dentists are involved in helping patients in tobacco cessation. The strong association of smoking with smokeless tobacco needs to be considered in designing cessation programs for adolescents. PMID:23904581

Pneumonyssoides caninum infection--a risk factor for gastric dilatation-volvulus in dogs.

PubMed

Bredal, W P

1998-06-01

The pathophysiology, clinical course and therapeutic management of gastric dilatation-volvulus (GDV) in dogs are well known. However, the aetiology remains elusive. Aerophagia has often been put forward as a contributing cause of GDV. The most common clinical sign in dogs with nasal mite (Pneumonyssoides caninum) infection is 'reversed sneezing', which may result in aerophagia. A prospective one-year necropsy study was conducted. Of 250 dogs, 17 were GDV cases and, of these, 35% had concurrent nasal mite infection compared to 5% in the control population. Multivariate logistic regression analyses performed using the 187 dogs with complete records included nasal mite infection status, age, weight and gender. Nasal mite infection was found to be the most important risk factor for GDV in this study, with an odds ratio and confidence interval of 27.6 (4.8-157.5). Other risk factors that were marginally significant included weight and age with odds ratios of 1.08 (1.02-1.13) and 1.37 (1.04-1.79), respectively. Gender was not found to be a significant risk factor for GDV. This study suggests that nasal mite infection may contribute to the development of GDV in otherwise predisposed dogs.

1999-11-15

There are few epidemiologic studies among adult nonsmokers on the effects of workplace environmental tobacco smoke on high density lipoprotein cholesterol (HDL-C). The authors investigated this relation, using data from health examinations conducted in 1995 on 3,062 Japanese nonsmokers in a total of 27 municipal offices with few smoking restrictions. Multiple regression analysis with adjustments for age, body mass index, alcohol drinking, and sports activities showed that in women, and in men lacking both alcohol consumption and sports activities characteristics, there were inverse linear relations between workplace smoking indices and HDL-C levels. Multivariate logistic regression showed that nonsmoking women in the upper two thirds of offices ranked by smoking intensity had an increased risk of low HDL-C levels (<45 mg), taking those in the lowest third of offices as reference (the medium third: odds ratio = 1.7; 95% confidence interval: 1.2, 2.5; the highest third: odds ratio = 1.6; 95% confidence interval: 1.1, 2.4). The results indicated that workplace environmental tobacco smoke exposure is associated with HDL-C among nonsmokers. However, the lack of data on home exposure limits causal inferences about the effects of workplace exposure.

Many physicians and surgeons think that prescribing antibiotics before intraoperative sampling does not alter the microbiological results. Case-control study of adult patients hospitalized with orthopedic infections. Among 2740 episodes of orthopedic infections, 1167 (43%) had received antibiotic therapy before surgical sampling. Among these, 220 (19%) grew no pathogens while the proportion of culture-negative results in the 2573 who had no preoperative antibiotic therapy was only 6%. By multivariate analyses, pre-operative antibiotic exposure was associated with significantly more culture-negative results (odds ratio 2.8, 95% confidence interval 2.1-3.7), more non-fermenting rods and skin commensals (odds ratio 2.8 and 3.0, respectively). Even a single pre-operative dose of antibiotic was significantly associated with subsequent culture-negative results (19/93 vs. 297/2350; χ²-test, p = 0.01) and skin commensals (17/74 vs. 274/2350; p = 0.01) compared to episodes without preceding prophylaxis. Prior antibiotic use, including single-dose prophylactic administrations, is three-fold associated with culture-negative results, non-fermenting rods and resistant skin commensals.

Background We examined the association between self-reported hearing protection use at work and incidence of hearing shifts over a 5-year period. Methods Audiometric data from 19,911 workers were analyzed. Two hearing shift measures—OSHA standard threshold shift (OSTS) and high-frequency threshold shift (HFTS)—were used to identify incident shifts in hearing between workers’ 2005 and 2009 audiograms. Adjusted odds ratios were generated using multivariable logistic regression with multi-level modeling. Results The odds ratio for hearing shift for workers who reported never versus always wearing hearing protection was nonsignificant for OSTS (OR 1.23, 95% CI 0.92–1.64) and marginally significant for HFTS (OR 1.26, 95% CI 1.00–1.59). A significant linear trend towards increased risk of HFTS with decreased use of hearing protection was observed (P = 0.02). Conclusion The study raises concern about the effectiveness of hearing protection as a substitute for noise control to prevent noise-induced hearing loss in the workplace. Am. J. Ind.

Tobacco smoking is an important problem among schoolchildren. The authors studied the patterns of tobacco smoking among schoolchildren in Colombo, Sri Lanka, using a self-administered questionnaire. Multistaged stratified random sampling was used to select 6000 students. Response rate was 90.7% (5446), out of which 53.4% were males. Prevalence rates for males and females, respectively, were as follows: having smoked at least 1 complete cigarette: 27.0% and 13.3%, smoked more than 100 cigarettes: 2.3% and 0.3%, daily smoking: 1.8% and 0.2%. Mean age of starting to smoke was 14.16 years. The tobacco products most used were cigarettes (91.5%) and bidis (3.8%). In univariate analysis, male gender, parental smoking, studying non-science subjects, peer smoking, and participating in sports were significantly associated with smoking of at least 1 complete cigarette (P < .05). In multivariate analysis, the most significant correlates were having close friends (odds ratio = 3.29, confidence interval = 2.47-4.37) or parents who smoked (odds ratio = 1.86, confidence interval = 1.28-2.71). Female smoking has increased from previously reported values. These high-risk groups can be targets for preventive programs. © 2013 APJPH.

To assess the association between peer relationship problems and childhood overweight and obesity. Data on 4718 preschool children were obtained at the obligatory school entry health examination in Bavaria. Parentally reported peer relationship problems ('normal', 'borderline' or 'abnormal') were assessed from the Strengths and Difficulties Questionnaire. Overweight and obesity were defined according to age- and gender-specific BMI cut-off points. Multivariate logistic regression analysis was performed to control potential confounders. The prevalence of overweight and obesity was higher among children with 'borderline' or 'abnormal' peer relationship problems compared to 'normal' children. The association of 'abnormal' peer relationship problems was still significant in the final logistic regression model for girls [odds ratio (OR) for overweight 2.0; 95% confidence interval (CI): 1.4-3.0; OR for obesity 2.6; 95% CI: 1.3-5.0]. Among boys the adjusted odds ratio were lower and no longer significant. The significantly increased prevalence of overweight and obesity among preschool children with peer relationship problems could not be explained by confounding. It seems evident that there is a relevant co-morbidity of peer relationship problems and obesity in pre-school children pointing to the need of interventions focusing on both physical as well as psychosocial health.

Abstract Objective To use mendelian randomisation to investigate whether 25-hydroxyvitamin D concentration has a causal effect on gestational hypertension or pre-eclampsia. Design One and two sample mendelian randomisation analyses. Setting Two European pregnancy cohorts (Avon Longitudinal Study of Parents and Children, and Generation R Study), and two case-control studies (subgroup nested within the Norwegian Mother and Child Cohort Study, and the UK Genetics of Pre-eclampsia Study). Participants 7389 women in a one sample mendelian randomisation analysis (751 with gestational hypertension and 135 with pre-eclampsia), and 3388 pre-eclampsia cases and 6059 controls in a two sample mendelian randomisation analysis. Exposures Single nucleotide polymorphisms in genes associated with vitamin D synthesis (rs10741657 and rs12785878) and metabolism (rs6013897 and rs2282679) were used as instrumental variables. Main outcome measures Gestational hypertension and pre-eclampsia defined according to the International Society for the Study of Hypertension in Pregnancy. Results In the conventional multivariable analysis, the relative risk for pre-eclampsia was 1.03 (95% confidence interval 1.00 to 1.07) per 10% decrease in 25-hydroxyvitamin D level, and 2.04 (1.02 to 4.07) for 25-hydroxyvitamin D levels <25 nmol/L compared with ≥75 nmol/L. No association was found for gestational hypertension. The one sample mendelian randomisation analysis using the total genetic risk score as an instrument did not provide strong evidence of a linear effect of 25-hydroxyvitamin D on the risk of gestational hypertension or pre-eclampsia: odds ratio 0.90 (95% confidence interval 0.78 to 1.03) and 1.19 (0.92 to 1.52) per 10% decrease, respectively. The two sample mendelian randomisation estimate gave an odds ratio for pre-eclampsia of 0.98 (0.89 to 1.07) per 10% decrease in 25-hydroxyvitamin D level, an odds ratio of 0.96 (0.80 to 1.15) per unit increase in the log(odds) of 25-hydroxyvitamin D level <75 nmol/L, and an odds ratio of 0.93 (0.73 to 1.19) per unit increase in the log(odds) of 25-hydroxyvitamin D levels <50 nmol/L. Conclusions No strong evidence was found to support a causal effect of vitamin D status on gestational hypertension or pre-eclampsia. Future mendelian randomisation studies with a larger number of women with pre-eclampsia or more genetic instruments that would increase the proportion of 25-hydroxyvitamin D levels explained by the instrument are needed.

Abdominal obesity is a key contributor of metabolic disease. Recent trials suggest that dietary fat quality affects abdominal fat content, where palmitic acid and linoleic acid influence abdominal obesity differently, while effects of n-3 polyunsaturated fatty acids are less studied. Also, fatty acid desaturation may be altered in abdominal obesity. We aimed to investigate cross-sectional associations of serum fatty acids and desaturases with abdominal obesity prevalence in a population-based cohort study. Serum cholesteryl ester fatty acids composition was measured by gas chromatography in 60-year old men (n = 1883) and women (n = 2015). Cross-sectional associations of fatty acids with abdominal obesity prevalence and anthropometric measures (e.g., sagittal abdominal diameter) were evaluated in multivariable-adjusted logistic and linear regression models, respectively. Similar models were employed to investigate relations between desaturase activities (estimated by fatty acid ratios) and abdominal obesity. In logistic regression analyses, palmitic acid, stearoyl-CoA-desaturase and Δ6-desaturase indices were associated with abdominal obesity; multivariable-adjusted odds ratios (95% confidence intervals) for highest versus lowest quartiles were 1.45 (1.19–1.76), 4.06 (3.27–5.05), and 3.07 (2.51–3.75), respectively. Linoleic acid, α-linolenic acid, docohexaenoic acid, and Δ5-desaturase were inversely associated with abdominal obesity; multivariable-adjusted odds ratios (95% confidence intervals): 0.39 (0.32–0.48), 0.74 (0.61–0.89), 0.76 (0.62–0.93), and 0.40 (0.33–0.49), respectively. Eicosapentaenoic acid was not associated with abdominal obesity. Similar results were obtained from linear regression models evaluating associations with different anthropometric measures. Sex-specific and linear associations were mainly observed for n3-polyunsaturated fatty acids, while associations of the other exposures were generally non-linear and similar across sexes. In accordance with findings from short-term trials, abdominal obesity was more common among individuals with relatively high proportions of palmitic acid, whilst the contrary was true for linoleic acid. Further trials should examine the potential role of linoleic acid and its main dietary source, vegetable oils, in abdominal obesity prevention. PMID:28125662

Study Objectives: Sleep-related complaints are common in adolescents, but their impact on the rate of motor vehicle crashes accidents is poorly known. We studied subjective sleep quality, driving habits, and self-reported car crashes in high-school adolescents. Methods: Self-administered questionnaires (with items exploring driving habits) were distributed to 339 students who had a driver's license and attended 1 of 7 high schools in Bologna, Italy. Statistical analysis were performed to describe lifestyle habits, sleep quality, sleepiness, and their relationship with the binary dependent variable (presence or absence of car crashes) to identify the factors significantly affecting the probability of car crashes in a multivariate binary logistic regression model. Results: Nineteen percent of the sample reported bad sleep, 64% complained of daytime sleepiness, and 40% reported sleepiness while driving. Eighty students (24%), 76% of which were males, reported that they had already crashed at least once, and 15% considered sleepiness to have been the main cause of their crash. As compared with adolescents who had not had a crash, those who had at least 1 previous crash reported that they more frequently used to drive (79% vs 62%), drove at night (25% vs 9%), drove while sleepy (56% vs 35%), had bad sleep (29% vs 16%), and used stimulants such as caffeinated soft drinks (32% vs 19%), tobacco (54% vs 27%), and drugs (21% vs 7%). The logistic procedure established a significant predictive role of male sex (p < 0.0001; odds ratio = 3.3), tobacco use (p < 0.0001; odds ratio = 3.2), sleepiness while driving (p = 0.010; odds ratio = 2.1), and bad sleep (p = 0.047; odds ratio = 1.9) for the crash risk. Conclusions: Our results confirm the high prevalence of sleep-related complaints among adolescents and highlight their independent role on self-reported crash risk.

Although hematopoietic cell transplantation (HCT) is the only curative therapy for many advanced hematologic cancers, little is known about the financial hardship experienced by HCT patients nor the association of hardship with patient-reported outcomes. We mailed a 43-item survey to adult patients approximately 180 days after their first autologous or allogeneic HCT at 3 high-volume centers. We assessed decreases in household income; difficulty with HCT-related costs, such as need to relocate or travel; and 2 types of hardship: hardship_1 (reporting 1 or 2 of the following: dissatisfaction with present finances, difficulty meeting monthly bill payments, or not having enough money at the end of the month) and "hardship_2" (reporting all 3). Patient-reported stress was measured with the Perceived Stress Scale-4, and 7-point scales were provided for perceptions of overall quality of life (QOL) and health. In total, 325 of 499 surveys (65.1%) were received. The median days since HCT was 173; 47% underwent an allogeneic HCT, 60% were male, 51% were > 60 years old, and 92% were white. Overall, 46% reported income decline after HCT, 56% reported hardship_1, and 15% reported hardship_2. In multivariable models controlling for income, those reporting difficulty paying for HCT-related costs were more likely to report financial hardship (odds ratio, 6.9; 95% confidence interval, 3.8 to 12.3). Hardship_1 was associated with QOL below the median (odds ratio, 2.9; 95% confidence interval, 1.7 to 4.9), health status below the median (odds ratio, 2.2; 95% confidence interval, 1.3 to 3.6), and stress above the median (odds ratio, 2.1; 95% confidence interval, 1.3 to 3.5). In this sizable cohort of HCT patients, financial hardship was prevalent and associated with worse QOL and higher levels of perceived stress. Interventions to address patient financial hardship-especially those that ameliorate HCT-specific costs-are likely to improve patient-reported outcomes.

This study was conducted to determine the prevalence and risk factors for Cryptosporidium infection in calf neonates on dairy farms in Normandy. Fecal samples were randomly collected between July 2010 and September 2011 from 968 calves (7-21 days old) on 97 farms. Up to 10 calves were selected and sampled per farm, and feces examined for oocysts by microscopy. C. parvum oocyst shedding was scored semi-quantitatively (0-5). A questionnaire about calf-level care and management was completed, and mortality rates were obtained from the French national registration database (BDNI). Bivariable and multivariable analyses of potential risk factors for C. parvum oocyst shedding were conducted using generalized estimating equation (GEE) models (family=Binomial).Overall, 402 out of 968 calves (41.5%) were positive for oocysts, and 25.1% of animals had a shedding score >2. Seven of the 97 farms (7%) were negative for oocysts in all fecal samples. At the time of collection, 375 calves (39%) had diarrhea, and its prevalence strongly correlated with the score for C. parvum oocyst shedding (p<0.0001). The mortality rate at 90 days was significantly greater for calves with high combined scores of diarrhea and shedding. Factors associated with the shedding of C. parvum were the Normande breed (odds ratio=1.49; 95% confidence interval (CI): 0.93-2.37), dispensing of colostrum using a bucket (odds ratio=1.37; 95% CI: 1.00-1.89), treatment with halofuginone (odds ratio=0.46; 95% CI: 0.19-1.15) and feeding with fermented milk (odds ratio=0.32; 95% CI: 0.17-0.63). C. parvum is widespread among calves under 21 days old in dairy herds of western France. Shedding of C. parvum is associated with a high incidence of diarrhea and increased risk of mortality in young calves. This study identified some associated calf-level factors, although further investigations are necessary to determine appropriate measures that farmers and veterinary practitioners should take to reduce the prevalence of C. parvum.

Paediatric hospital-associated venous thromboembolism is a leading quality and safety concern at children's hospitals. The aim of this study was to determine risk factors for hospital-associated venous thromboembolism in critically ill children following cardiothoracic surgery or therapeutic cardiac catheterisation. We conducted a retrospective, case-control study of children admitted to the cardiovascular intensive care unit at Johns Hopkins All Children's Hospital (St. Petersburg, Florida, United States of America) from 2006 to 2013. Hospital-associated venous thromboembolism cases were identified based on ICD-9 discharge codes and validated using radiological record review. We randomly selected two contemporaneous cardiovascular intensive care unit controls without hospital-associated venous thromboembolism for each hospital-associated venous thromboembolism case, and limited the study population to patients who had undergone cardiothoracic surgery or therapeutic cardiac catheterisation. Odds ratios and 95% confidence intervals for associations between putative risk factors and hospital-associated venous thromboembolism were determined using univariate and multivariate logistic regression. Among 2718 admissions to the cardiovascular intensive care unit during the study period, 65 met the criteria for hospital-associated venous thromboembolism (occurrence rate, 2%). Restriction to cases and controls having undergone the procedures of interest yielded a final study population of 57 hospital-associated venous thromboembolism cases and 76 controls. In a multiple logistic regression model, major infection (odds ratio=5.77, 95% confidence interval=1.06-31.4), age ⩽1 year (odds ratio=6.75, 95% confidence interval=1.13-160), and central venous catheterisation (odds ratio=7.36, 95% confidence interval=1.13-47.8) were found to be statistically significant independent risk factors for hospital-associated venous thromboembolism in these children. Patients with all three factors had a markedly increased post-test probability of having hospital-associated venous thromboembolism. Major infection, infancy, and central venous catheterisation are independent risk factors for hospital-associated venous thromboembolism in critically ill children following cardiothoracic surgery or cardiac catheter-based intervention, which, in combination, define a high-risk group for hospital-associated venous thromboembolism.

Advancements in diagnosis and treatment have resulted in better clinical outcomes after stroke; however, the influence of age and gender on recent trends in death during stroke hospitalization has not been specifically investigated. We assessed the impact of age and gender on nationwide patterns of in-hospital mortality after stroke. Data were obtained from all US states that contributed to the Nationwide Inpatient Sample. All patients admitted to hospitals between 1997 and 1998 (n=1 351 293) and 2005 and 2006 (n=1 202 449), with a discharge diagnosis of stroke (identified by the International Classification of Diseases, Ninth Revision procedure codes), were included. Time trends for in-hospital mortality after stroke were evaluated by gender and age group based on 10-year age increments (<55, 55-64, 65-74, 75-84, >84) using multivariable logistic regression. Between 1997 and 2006, in-hospital mortality rates decreased across time in all sub-groups (all P<0·01), except in men >84 years. In unadjusted analysis, men aged >84 years in 1997-1998 had poorer mortality outcomes than similarly aged women (odds ratio 0·93, 95% confidence interval=0·88-0·98). This disparity worsened by 2005-2006 (odds ratio 0·88, 95% confidence interval=0·84-0·93). After adjusting for confounders, compared with similarly aged women, the mortality outcomes among men aged >84 years were poorer in 1997-1998 (odds ratio 0·97, 95% confidence interval=0·92-1·02) and were poorer in 2005-2006 (odds ratio 0·92, 95% confidence interval=0·87-0·96), P=0·04, for gender × time trend. Over the last decade, in-hospital mortality rates after stroke in the United States have declined for every age/gender group, except men aged >84 years. Given the rapidly ageing US population, avenues for boosting in-hospital survival among very elderly men with stroke need to be explored. © 2011 The Authors.

To describe the consecutive pregnancy outcome and treatment in refractory obstetrical antiphospholipid syndrome (APS). Retrospective multicenter open-labelled study from December 2015 to June 2016. We analyzed the outcome of pregnancies in patients with obstetrical APS (Sydney criteria) and previous adverse obstetrical event despite low-dose aspirin and low-molecular weight heparin LMWH (LMWH) conventional treatment who experienced at least one subsequent pregnancy. Forty nine patients with median age 27years (23-32) were included from 8 European centers. Obstetrical APS was present in 71%, while 26% had obstetrical and thrombotic APS. Lupus anticoagulant was present in 76% and triple antiphospholipid antibody (APL) positivity in 45% of patients. Pregnancy loss was noted in 71% with a median age of gestation of 11 (8-21) weeks. The presence of APS non-criteria features (35% vs 17% in pregnancies without adverse obstetrical event; p=0.09), previous intrauterine death (65% vs 38%; p=0.06), of LA (90% vs 65%; p=0.05) were more frequent in pregnancies with adverse pregnancy outcome, whereas isolated recurrent miscarriage profile was more frequent in pregnancies without any adverse pregnancy outcome (15% vs 41%; p=0.04). In univariate analysis considering all pregnancies (index and subsequent ones), an history of previous intrauterine death was associated with pregnancy loss (odds-ratio 2.51 (95% CI 1.274.96); p=0.008), whereas previous history of prematurity related to APS (odds-ratio 0.13 95%CI 0.04 0.41, P=0.006), steroids use during the pregnancy (odds-ratio 0.30 95% CI 0.11-0.82, p=0.019) and anticardiolipids isolated profile (odds-ratio 0.51 95% CI 0.26-1.03, p=0.0588) were associated with favorable outcome. In multivariate analysis, only previous history of prematurity, steroids use and anticardiolipids isolated profiles were associated with live-birth pregnancy. The main features of refractory obstetrical APS were the high rates of LA and triple APL positivity. Steroids could be effective in this APS profile, but prospective studies are necessary.

Identification of risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy is necessary for evidence-based risk reduction and adequate patient counseling. To identify risk factors for adverse obstetrical outcomes after appendectomy and cholecystectomy during pregnancy and stratify the risk of such outcomes. A cohort study was conducted using the Nationwide Inpatient Sample, a nationally representative sample of patients discharged from community hospitals in the United States, from January 1, 2003, to December 31, 2012. Multivariable analysis of risk factors for adverse obstetric outcomes was performed for 19 926 women undergoing appendectomy or cholecystectomy during pregnancy and a scoring system for such risk factors was developed. Data analysis was conducted from January 1, 2015, to July 31, 2016. A composite measure including 7 adverse obstetrical outcomes throughout pregnancy and occurring before hospital discharge. Of the 19 926 women (mean [SD] age, 26 [6] years) in the study, 1018 adverse obstetrical events were recorded in 953 pregnant women (4.8%). The 3 most frequent adverse events were preterm delivery (360 [35.4%]), preterm labor without preterm delivery (269 [26.4%]), and miscarriage (262 [25.7%]). The risk factors associated most strongly with an adverse obstetrical outcome included cervical incompetence (adjusted odds ratio, 24.29; 95% CI, 7.48-78.81), preterm labor during current pregnancy (adjusted odds ratio, 18.34; 95% CI, 4.95-67.96), vaginitis or vulvovaginitis (adjusted odds ratio, 5.17; 95% CI, 2.19-12.23), and sepsis (adjusted odds ratio, 3.39; 95% CI, 2.08-5.51). A scoring system based on statistically significant variables classified the study sample into 3 risk groups corresponding to predicted probabilities of adverse obstetrical outcomes of 2.5% (≤4 points), 8.2% (5-8 points), and 21.8% (≥9 points). Approximately 5% of women experience adverse obstetrical outcomes after appendectomy or cholecystectomy during pregnancy. The major risk factors for such outcomes are cervical incompetence, preterm labor during current pregnancy, vaginitis or vulvovaginitis, and sepsis.

Results Of the 19 926 women (mean [SD] age, 26 [6] years) in the study, 1018 adverse obstetrical events were recorded in 953 pregnant women (4.8%). The 3 most frequent adverse events were preterm delivery (360 [35.4%]), preterm labor without preterm delivery (269 [26.4%]), and miscarriage (262 [25.7%]). The risk factors associated most strongly with an adverse obstetrical outcome included cervical incompetence (adjusted odds ratio, 24.29; 95% CI, 7.48-78.81), preterm labor during current pregnancy (adjusted odds ratio, 18.34; 95% CI, 4.95-67.96), vaginitis or vulvovaginitis (adjusted odds ratio, 5.17; 95% CI, 2.19-12.23), and sepsis (adjusted odds ratio, 3.39; 95% CI, 2.08-5.51). A scoring system based on statistically significant variables classified the study sample into 3 risk groups corresponding to predicted probabilities of adverse obstetrical outcomes of 2.5% (≤4 points), 8.2% (5-8 points), and 21.8% (≥9 points). Conclusions and Relevance Approximately 5% of women experience adverse obstetrical outcomes after appendectomy or cholecystectomy during pregnancy. The major risk factors for such outcomes are cervical incompetence, preterm labor during current pregnancy, vaginitis or vulvovaginitis, and sepsis. PMID:28114513

Metal welding produces gaseous fumes that contain manganese, resulting in potential occupational exposure to welders. It has been hypothesized that occupational exposure among welders could increase risk of Parkinson's disease and other neurodegenerative diseases. The present study examines welding occupation and mortality from neurodegenerative diseases among men in the United States using the National Cause of Death databases 1985 to 1999. Information was abstracted from death certificates for states that collected data on occupation. Of 4,252,490 men who died during the study period, 107,773 had welding-related occupations. Multivariable logistic regression models were used to calculate mortality odds ratios (MOR) and 95% confidence intervals (CI) for odds of dying from Parkinson's disease or other neurodegenerative diseases among men who were welders as compared with men of other occupations, adjusting for attained age, race, region of residence, and year of death. During the study period, 49,174 deaths were attributed to Parkinson's disease, 54,892 to Alzheimer's disease, and 19,018 to presenile dementia. There was no evidence of an increased odds of Parkinson's disease mortality among welders as compared with men with other occupations (MOR = 0.83, 95% CI 0.78-0.88). Furthermore, welding occupation was unrelated to the odds of mortality from Alzheimer's disease (MOR = 0.94, 95% CI 0.89-1.00) or presenile dementia (MOR = 0.96, 95% CI 0.87-1.06). Earlier research suggested that welding exposures could predispose individuals to earlier onset Parkinson's disease. However, there was no evidence in this data of an increased mortality odds ratio associated with welding occupations among men younger than 65 (MOR = 1.03, 95% CI 0.74-1.44); while there was a suggestion of a lower odds Parkinson's disease death among men age 65 years and older (MOR = 0.82, 95% CI 0.77-0.88). Data from this large study do not support an association between welding occupations and death from Parkinson's disease or other neurodegenerative diseases, nor that welders are at increased odds of dying from Parkinson's disease at a younger age.

In addition to relative risk, relative risk reduction and absolute risk reduction there circulates another effect size for binary endpoints in the scientific medical literature: the odds ratio. Relative risk and odds ratio are alternative ways of reflecting study results. Both, relative risk (RR) and odds ratio (OR), can easily be calculated from the "2 x 2-table". Advantage of OR: odds ratios can be calculated in every type of controlled study design, including retrospective studies. Furthermore, odds ratios--the biostatisticians are swarming--offer beautiful mathematical properties and therefore are often used in meta-analysis as an effect size for calculating a pooled estimate of the results of different studies with the same clinical question. Disadvantage of OR: In clinical studies the presentation of the results as "odds ratios" may result in an overestimation of the intervention effect. This article shows the difference between "chance" and "risk" and how odds ratio and relative risk are associated.

OBJECTIVE: To examine the associations between depression in fathers of 1-year-old children and specific positive and negative parenting behaviors discussed by pediatric providers at well-child visits. METHODS: We performed a cross-sectional secondary analysis by using interview data from 1746 fathers of 1-year-old children in the Fragile Families and Child Wellbeing Study. Positive parenting behaviors included fathers' reports of playing games, singing songs, and reading stories to their children ≥3 days in a typical week. Negative parenting behavior included fathers' reports of spanking their 1-year-old children in the previous month. Depression was assessed by using the World Health Organization Composite International Diagnostic Interview Short Form. Weighted bivariate and multivariate analyses of parenting behaviors were performed while controlling for demographics and paternal substance abuse. RESULTS: Overall, 7% of fathers had depression. In bivariate analyses, depressed fathers were more likely than nondepressed fathers to report spanking their 1-year-old children in the previous month (41% compared with 13%; P < .01). In multivariate analyses, depressed fathers were less likely to report reading to their children ≥3 days in a typical week (adjusted odds ratio: 0.38 [95% confidence interval: 0.15–0.98]) and much more likely to report spanking (adjusted odds ratio: 3.92 [95% confidence interval: 1.23–12.5]). Seventy-seven percent of depressed fathers reported talking to their children's doctor in the previous year. CONCLUSIONS: Paternal depression is associated with parenting behaviors relevant to well-child visits. Pediatric providers should consider screening fathers for depression, discussing specific parenting behaviors (eg, reading to children and appropriate discipline), and referring for treatment if appropriate.

Red blood cell transfusion was previously the principle therapy for anemia in CKD but became less prevalent after the introduction of erythropoiesis-stimulating agents. This study used adaptive choice-based conjoint analysis to identify preferences and predictors of transfusion decision-making in CKD. A computerized adaptive choice-based conjoint survey was administered between June and August of 2012 to nephrologists, internists, and hospitalists listed in the American Medical Association Masterfile. The survey quantified the relative importance of 10 patient attributes, including hemoglobin levels, age, occult blood in stool, severity of illness, eligibility for transplant, iron indices, erythropoiesis-stimulating agents, cardiovascular disease, and functional status. Triggers of transfusions in common dialysis scenarios were studied, and based on adaptive choice-based conjoint-derived preferences, relative importance by performing multivariable regression to identify predictors of transfusion preferences was assessed. A total of 350 providers completed the survey (n=305 nephrologists; mean age=46 years; 21% women). Of 10 attributes assessed, absolute hemoglobin level was the most important driver of transfusions, accounting for 29% of decision-making, followed by functional status (16%) and cardiovascular comorbidities (12%); 92% of providers transfused when hemoglobin was 7.5 g/dl, independent of other factors. In multivariable regression, Veterans Administration providers were more likely to transfuse at 8.0 g/dl (odds ratio, 5.9; 95% confidence interval, 1.9 to 18.4). Although transplant eligibility explained only 5% of decision-making, nephrologists were five times more likely to value it as important compared with non-nephrologists (odds ratio, 5.2; 95% confidence interval, 2.4 to 11.1). Adaptive choice-based conjoint analysis was useful in predicting influences on transfusion decisions. Hemoglobin level, functional status, and cardiovascular comorbidities most strongly influenced transfusion decision-making, but preference variations were observed among subgroups.

Recent guidelines recommend that all cirrhotics undergo screening upper endoscopy to identify those patients at risk for bleeding from varices. However, this practice may not be cost effective as large esophageal varices are seen only in 9-36% of these patients. The aim of this study was to determine whether clinical variables were predictive of the presence of large esophageal varices. This is a retrospective analysis of cirrhotics who had a screening upper endoscopy during an evaluation for liver transplantation at three different centers and who had not previously bled from varices. A multivariate model was derived on the combined cohort using logistic regression. Three hundred forty-six patients were eligible for the study. The prevalence of large esophageal varices was 20%. On multivariate analysis, splenomegaly detected by computed tomographic scan (odds ratio: 4.3; 95% confidence interval: 1.6-11.5) or by physical examination (odds ratio: 2.0; 95% confidence interval: 1.1-3.8), and low platelet count were independent predictors of large esophageal varices. On the basis of these variables, cirrhotics were stratified into high- and low-risk groups for the presence of large esophageal varices. Patients with a platelet count of > or = 88,000/mm3 (median value) and no splenomegaly by physical examination had a risk of large esophageal varices of 7.2%. Those with splenomegaly or platelet count < 88,000/mm3 had a risk of large esophageal varices of 28% (p < 0.0001). Our data show that clinical predictors could be used to stratify cirrhotic patients for the risk of large esophageal varices and such stratification could be used to improve the cost effectiveness of screening endoscopy.

Little is known about paternal psychosocial factors and childhood asthma. We sought to examine the link between maternal and paternal psychosocial stress and asthma outcomes in young children. Parents of 339 pairs of Puerto Rican twins were interviewed individually about their own psychosocial stress and about asthma in their children at age 1 year and again about their child's asthma at age 3 years. Fathers were asked about symptoms of posttraumatic stress disorder (PTSD), depression, and antisocial behavior. Mothers were asked about depressive symptoms. Outcomes assessed in children included recent asthma symptoms, oral steroid use and hospitalizations for asthma in the prior year, and asthma diagnosis. Generalized estimated equation models were used for the multivariate analysis of parental psychosocial stress and asthma morbidity in childhood. After multivariable adjustment, paternal PTSD symptoms, depression, and antisocial behavior were each associated with increased asthma symptoms at age 1 year (eg, odds ratio, 1.08 for each 1-point increase in PTSD score; 95% CI, 1.03-1.14). Maternal depressive symptoms were associated with an increased risk of asthma hospitalizations at age 1 year. At age 3 years, maternal depressive symptoms were associated with asthma diagnosis and hospitalizations for asthma (odds ratio for each 1-point increase in symptoms, 1.16; 95% CI, 1.00-1.36). In an analysis combining 1- and 3-year outcomes, paternal depression was associated with oral steroid use, maternal depressive symptoms were associated with asthma hospitalizations and asthma diagnosis, and parental depression was associated with hospitalizations for asthma. Both paternal and maternal psychosocial factors can influence asthma morbidity in young Puerto Rican children. Copyright © 2010 American Academy of Allergy, Asthma & Immunology.

Objective Physician participation in Continuing Medical Education programs may be influenced by a number of factors. To evaluate the factors associated with compliance with the Continuing Medical Education requirements at a private hospital, we investigated whether physicians’ activity, measured by volumes of admissions and procedures, was associated with obtaining 40 Continuing Medical Education credits (40 hours of activities) in a 12-month cycle. Methods In an exclusive and non-mandatory Continuing Medical Education program, we collected physicians’ numbers of hospital admissions and numbers of surgical procedures performed. We also analyzed data on physicians’ time since graduation, age, and gender. Results A total of 3,809 credentialed, free-standing, private practice physicians were evaluated. Univariate analysis showed that the Continuing Medical Education requirements were more likely to be achieved by male physicians (odds ratio 1.251; p=0.009) and who had a higher number of hospital admissions (odds ratio 1.022; p<0.001). Multivariate analysis showed that age and number of hospital admissions were associated with achievement of the Continuing Medical Education requirements. Each hospital admission increased the chance of achieving the requirements by 0.4%. Among physicians who performed surgical procedures, multivariate analysis showed that male physicians were 1.3 time more likely to achieve the Continuing Medical Education requirements than female physicians. Each surgical procedure performed increased the chance of achieving the requirements by 1.4%. Conclusion The numbers of admissions and number of surgical procedures performed by physicians at our hospital were associated with the likelihood of meeting the Continuing Medical Education requirements. These findings help to shed new light on our Continuing Medical Education program. PMID:25807247

Socioeconomic inequalities in oral health have been reported in developed countries, but the influence of marital status has rarely been considered. Our aim was to examine marital status differentials in the association between socioeconomic status (SES) and oral health among community-dwelling Japanese women. From 2010 to 2011, a questionnaire survey was conducted among residents aged 25-50 years in Japanese metropolitan areas. Valid responses were received from 626 unmarried women and 1,620 married women. Women's own and husbands' educational attainment and equivalent income were used to assess SES. Self-rated "fair" or "poor" oral health was defined as poor oral health. Multiple logistic regression analysis was conducted to examine which SES indicators were associated with oral health. The prevalence of poor oral health was 21.1% among unmarried women and 23.8% among married women. Among unmarried women, equivalent income was not associated with oral health, but women's own education was significantly associated with oral health; the multivariate-adjusted odds ratio of poor oral health among those with high school education or lower compared to those with university education or higher was 2.14 (95% confidence interval, 1.19-3.87). Among married women, neither women's own nor husbands' education was associated with oral health, but equivalent income was significantly associated with oral health, particularly among housewives; the multivariate-adjusted odds ratio of poor oral health among those in the lowest compared with highest income quartile was 1.57 (95% confidence interval, 1.08-2.27). These findings indicate that marital status should be considered when examining associations between SES and oral health among Japanese women.

To clarify the effectiveness of dietary diversity, calculated by dietary records, on cognitive decline. Data were derived from the National Institute for Longevity Sciences - Longitudinal Study of Aging. Participants comprised 298 men and 272 women aged 60-81 years at baseline (second wave) who participated in the follow-up study (third to seventh wave) at least once. Cognitive function was assessed with the Mini-Mental State Examination in all study waves. Dietary diversity was determined using the Quantitative Index for Dietary Diversity based on a 3-day dietary record in the second wave. Cumulative data among participants with a Mini-Mental State Examination score >27 in the second wave were analyzed using a generalized estimating equation. Multivariate adjusted odds ratios and 95% confidence intervals for Mini-Mental State Examination scores ≤27 in each study wave according to a 1 standard deviation (increase), or quartiles of the Quantitative Index for Dietary Diversity at baseline, were adjusted for sex, age, follow-up time, baseline Mini-Mental State Examination score, education, body mass index, annual household income, current smoking status, energy intake and disease history. Multivariate adjusted odds ratio for a decline in Mini-Mental State Examination score was 0.79 (95% CI 0.70-0.89; P < 0.001) with a 1 SD increase in dietary diversity score, or 1.00 (reference), 0.99 (95% CI 0.70-1.43), 0.68 (95% CI 0.46-0.99) and 0.56 (95% CI 0.38-0.83) according to the lowest through highest quartiles of dietary diversity score, respectively (trend P = 0.001). Daily intake of various kinds of food might be a protective factor against cognitive decline in community-dwelling Japanese older adults.

With improved cancer survival rates and the current trend of delaying parenthood, fertility is a growing issue among cancer patients. The purpose of this study was to evaluate the incidence of fertility counseling and sperm banking in reproductive-age male cancer patients and to assess factors that influence counseling and banking. Male patients ages 13 to 50 years who received a new cancer diagnosis from January 1, 2013, to May 1, 2015, and planned to initiate curative chemotherapy at our center were identified. Documentation of fertility counseling and sperm cryopreservation was abstracted from the medical record. Univariable and multivariable logistic regression modeling was used to examine variables associated with fertility counseling and sperm banking. Of 201 patients who fit the study criteria, 59 (29%) received fertility counseling and 23 (11%) attempted sperm banking. All patients who banked sperm had documentation of fertility counseling. Younger patients were significantly more likely to be counseled, with mean ages of 27.4 and 40.4 years for counseled and noncounseled patients, respectively (P < .001). Among counseled patients, those with a lower median income (P = .038) or who had Medicaid or no insurance (P = .042) were less likely to bank sperm. In a multivariable logistic regression model, older age (5-year odds ratio, 0.61; P < .001) and presence of comorbidities (odds ratio, 0.15; P = .03) remained significantly associated with a lower counseling rate. There is a low rate of fertility counseling and referral for sperm banking in young men with cancer receiving chemotherapy. Further work is needed to develop interventions to improve fertility counseling rates and opportunities for sperm banking. Copyright © 2016 by American Society of Clinical Oncology.

Because of the unique physiology and comorbidities of injured geriatric patients, specific interventions are needed to improve outcomes. The purpose of this study was to assess the effect of a change in triage criteria for injured geriatric patients evaluated at an American College of Surgeons Level I trauma center. As of October 1, 2013, all injured patients 70 years or older were mandated to have the highest-level trauma activation upon emergency department (ED) arrival regardless of physiology or mechanism of injury. Patients admitted before that date were designated as PRE; those admitted after were designated as POST. The study period was from October 1, 2011, through April 30, 2015. Data collected included demographics, mechanism of injury, hypotension on admission, comorbidities, Injury Severity Score (ISS), ED length of stay (LOS), complications, and mortality. Bivariate and multivariable analyses were used to compare outcomes between the study groups (p < 0.05 was considered significant). χ or Fisher's exact test was used as appropriate for bivariate analyses of categorical variables; patients' ages were compared using the Wilcoxon rank-sum test. A total of 2,269 patients (mean, 80.63 years; mean ISS, 12.2; PRE, 1,271; POST, 933) were included in the study. On multivariable analysis, increasing age, higher ISS, and hypotension were associated with higher mortality. POST patients were more likely to have an ED LOS of 2 hours or shorter (odds ratio, 1.614; 95% confidence interval, 1.088-2.394) after controlling for hypotension, ISS, and comorbidities. POST mortality significantly decreased (odds ratio, 0.689; 95% confidence interval, 0.484-0.979). Based on age alone, the focused intervention of a higher level of trauma activation decreased ED LOS and mortality in injured geriatric patients. Therapeutic/care management study, level IV.

The factors associated with hepatitis C virus (HCV) treatment uptake and responses were assessed among HCV/HIV co-infected individuals referred for HCV therapy at an urban HIV clinic. Retrospective review of HIV/HCV patients enrolled in the HCV treatment program at the John Ruedy Immunodeficiency Clinic in Vancouver. The factors associated with treatment uptake were assessed using multivariate analysis. A total of 134 HCV/HIV co-infected individuals were recalled for assessment for HCV therapy. Overall 64 (48%) initiated treatment, and of those treated 49 (76.6%) attained end treatment response, whereas 35 (57.8%) achieved sustained virological response (SVR). When evaluated by genotype, 53% (17/32) of those with genotype 1, and 65% (20/31) of those with genotype 2 or 3 infections attained SVR. In treated individuals, alanine aminotransferase dropped significantly after treatment (P<0.001). During treatment, CD4 counts dropped significantly (P<0.001) in all patients. The counts recovered to baseline in patients who achieved SVR, but remained lower in patients who failed the therapy (P=0.015). On multivariate analysis, history of injection drug use (odds ratio: 3.48; 95% confidence interval: 1.37-8.79; P=0.009) and low hemoglobin levels (odds ratio: 4.23; 95% confidence interval: 1.36-13.10; P=0.013) were associated with those who did not enter the treatment. Only half of treatment-eligible co-infected patients referred for the therapy initiated treatment. Of those referred for the therapy, history of injection drug use was associated with lower rates of treatment uptake. Treated HIV/HCV co-infected individuals benefitted from both decreased alanine aminotransferase (independent of SVR), and rates of SVR similar to those described in HCV monoinfected patients.

Little is known about risk factors for Tourette syndrome (TS) and chronic tic disorders (CT) but maternal psychological morbidity in pregnancy may be associated with TS/CT. We examined whether pre- and post-natal parental anxiety and/or depression are associated with risk of TS/CT in the Avon Longitudinal Study of Parents and Children. We compared self-reported anxiety and depression measures collected prospectively at four time points (18 and 32 weeks prenatally, and 8 weeks and 8 months post-natally) among parents of children who subsequently met criteria for TS/CT at 13 years of age as compared to other children from the cohort. We adjusted for various socioeconomic measures and tested both for time period-specific exposure and chronic exposure using multivariable logistic regression models. 122 children had TS/CT (50 TS, 72 CT) and 5968 children had no tics. In crude analyses, both pre- and post-natal maternal anxiety and depression, but only post-natal paternal depression at 8 months, showed associations with TS/CT. In the final, adjusted multivariable models, chronic maternal anxiety (odds ratio 2.17, 95% CI 1.23, 3.84, p = 0.007) and pre-natal maternal depression (odds ratio 1.86, 95% CI 1.02, 3.39, p = 0.04) showed associations with TS/CT though the latter was consistent with chance (p = 0.07) after adjustment for past maternal depression. We find associations between maternal psychological morbidity pre- and post-natally and risk of future TS/CT in offspring. These associations may reflect either shared genetic susceptibility or a pre-natal exposure. Further work is required to see if these findings can be replicated in larger datasets.

In Rwanda, significant progress has been made in advancing access to antiretroviral therapy (ART) among youth. As availability of ART increases, adherence is critical for preventing poor clinical outcomes and transmission of HIV. The goals of the study are to (1) describe ART adherence and mental health problems among youth living with HIV aged 10 to 17; and (2) examine the association between these factors among this population in rural Rwanda. A cross-sectional analysis was conducted that examined the association of mental health status and ART adherence among youth (n = 193). ART adherence, mental health status, and related variables were examined based on caregiver and youth report. Nonadherence was defined as ever missing or refusing a dose of ART within the past month. Multivariate modeling was performed to examine the association between mental health status and ART adherence. Approximately 37% of youth missed or refused ART in the past month. In addition, a high level of depressive symptoms (26%) and attempt to hurt or kill oneself (12%) was observed in this population of youth living with HIV in Rwanda. In multivariate analysis, nonadherence was significantly associated with some mental health outcomes, including conduct problems (odds ratio 2.90, 95% confidence interval 1.55-5.43) and depression (odds ratio 1.02, 95% confidence interval 1.01-1.04), according to caregiver report. A marginally significant association was observed for youth report of depressive symptoms. The findings suggest that mental health should be considered among the factors related to ART nonadherence in HIV services for youth, particularly for mental health outcomes, such as conduct problems and depression.

The utility of computed tomographic perfusion (CTP)-based patient selection for intra-arterial treatment of acute ischemic stroke has not been proven in randomized trials and requires further study in a cohort that was not selected based on CTP. Our objective was to study the relationship between CTP-derived parameters and outcome and treatment effect in patients with acute ischemic stroke because of a proximal intracranial arterial occlusion. We included 175 patients who underwent CTP in the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in The Netherlands (MR CLEAN). Association of CTP-derived parameters (ischemic-core volume, penumbra volume, and percentage ischemic core) with outcome was estimated with multivariable ordinal logistic regression as an adjusted odds ratio for a shift in the direction of a better outcome on the modified Rankin Scale. Interaction between CTP-derived parameters and treatment effect was determined using multivariable ordinal logistic regression. Interaction with treatment effect was also tested for mismatch (core <70 mL; penumbra core >1.2; penumbra core >10 mL). The adjusted odds ratio for improved functional outcome for ischemic core, percentage ischemic core, and penumbra were 0.79 per 10 mL (95% confidence interval: 0.71-0.89; P<0.001), 0.82 per 10% (95% confidence interval: 0.66-0.90; P=0.002), and 0.97 per 10 mL (96% confidence interval: 0.92-1.01; P=0.15), respectively. No significant interaction between any of the CTP-derived parameters and treatment effect was observed. We observed no significant interaction between mismatch and treatment effect. CTP seems useful for predicting functional outcome, but cannot reliably identify patients who will not benefit from intra-arterial therapy. © 2015 American Heart Association, Inc.

Background Multicenter data regarding cardiac arrest in children undergoing heart operations are limited. We describe epidemiology and outcomes associated with postoperative cardiac arrest in a large multiinstitutional cohort. Methods Patients younger than 18 years in the Society of Thoracic Surgeons Congenital Heart Surgery Database (2007 through 2012) were included. Patient factors, operative characteristics, and outcomes were described for patients with and without postoperative cardiac arrest. Multivariable models were used to evaluate the association of center volume with cardiac arrest rate and mortality after cardiac arrest, adjusting for patient and procedural factors. Results Of 70,270 patients (97 centers), 1,843 (2.6%) had postoperative cardiac arrest. Younger age, lower weight, and presence of preoperative morbidities (all p < 0.0001) were associated with cardiac arrest. Arrest rate increased with procedural complexity across common benchmark operations, ranging from 0.7% (ventricular septal defect repair) to 12.7% (Norwood operation). Cardiac arrest was associated with significant mortality risk across procedures, ranging from 15.4% to 62.3% (all p < 0.0001). In multivariable analysis, arrest rate was not associated with center volume (odds ratio, 1.06; 95% confidence interval, 0.71 to 1.57 in low- versus high-volume centers). However, mortality after cardiac arrest was higher in low-volume centers (odds ratio, 2.00; 95% confidence interval, 1.52 to 2.63). This association was present for both high- and low-complexity operations. Conclusions Cardiac arrest carries a significant mortality risk across the stratum of procedural complexity. Although arrest rates are not associated with center volume, lower-volume centers have increased mortality after cardiac arrest. Further study of mechanisms to prevent cardiac arrest and to reduce mortality in those with an arrest is warranted. PMID:25443018

HIV-infected individuals with non-AIDS-defining cancers are less likely to receive cancer treatment compared with uninfected individuals. We sought to identify provider-level factors influencing the delivery of oncology care to HIV-infected patients. A survey was mailed to 500 randomly selected US medical and radiation oncologists. The primary outcome was delivery of standard treatment, assessed by responses to three specialty-specific management questions. We used the χ(2) test to evaluate associations between delivery of standard treatment, provider demographics, and perceptions of HIV-infected individuals. Multivariable logistic regression identified associations using factor analysis to combine several correlated survey questions. Our response rate was 60%; 69% of respondents felt that available cancer management guidelines were insufficient for the care of HIV-infected patients with cancer; 45% never or rarely discussed their cancer management plan with an HIV specialist; 20% and 15% of providers were not comfortable discussing cancer treatment adverse effects and prognosis with their HIV-infected patients with cancer, respectively; 79% indicated that they would provide standard cancer treatment to HIV-infected patients. In multivariable analysis, physicians comfortable discussing adverse effects and prognosis were more likely to provide standard cancer treatment (adjusted odds ratio, 1.52; 95% CI, 1.12 to 2.07). Physicians with concerns about toxicity and efficacy of treatment were significantly less likely to provide standard cancer treatment (adjusted odds ratio, 0.67; 95% CI, 0.53 to 0.85). Provider-level factors are associated with delivery of nonstandard cancer treatment to HIV-infected patients. Policy change, provider education, and multidisciplinary collaboration are needed to improve access to cancer treatment. Copyright © 2015 by American Society of Clinical Oncology.

Corticosteroids are effective rescue therapies for patients with inflammatory bowel disease (IBD), but have significant side effects, which may be amplified in the growing population of elderly patients with IBD. We aimed to compare the use of steroids and steroid-sparing therapies (immunomodulators and biologics) and rates of complications among elderly (≥65) and younger patients in a national cohort of veterans with IBD. We used national Veterans Health Administrative data to conduct a retrospective study of veterans with IBD between 2002 and 2010. Medications and the incidence of complications were obtained from the Veterans Health Administrative Decision Support Systems. Multivariate logistic regression accounting for facility-level clustering was used to identify predictors of use of steroid-sparing medications. We identified 30,456 veterans with IBD. Of these, 94% were men and 40% were more than 65, and 32% were given steroids. Elderly veterans were less likely to receive steroids (23.8% versus 38.3%, P < 0.001) and were less likely to be prescribed steroid-sparing medications (25.5% versus 46.9%, respectively, P < 0.001). In multivariate analysis controlling for sex, age <65 (odds ratio, 2.19; 95% CI, 1.54-3.11) and gastroenterology care (odds ratio, 8.42; 95% CI, 6.18-11.47) were associated with initiation of steroid-sparing medications. After starting steroids, fracture rates increased in the elderly patients with IBD, whereas increases in venous thromboembolism and infections after starting steroids affected both age groups. Elderly veterans are less likely to receive steroids and steroid-sparing medications than younger veterans; elderly patients exposed to steroids were more likely to have fractures than the younger population.

Nicotinamide N-methyltransferase (NNMT) is a novel histone methylation modulator that regulates energy metabolism, and NNMT knockdown prevents diet-induced obesity in mice. However, whether NNMT plays a role in human obesity and type 2 diabetes (T2DM) remains to be elucidated. NNMT catalyzes methylation of nicotinamide to generate N(1)-methylnicotinamide (me-NAM). We aimed to investigate the associations of serum me-NAM with obesity and T2DM in Chinese. The study subjects (n = 1160) were recruited from Dali, a city of Yunnan Province, in southwest China. Anthropometric phenotypes, fasting glucose, and serum lipids were measured. Serum me-NAM was measured by liquid chromatography-mass spectrometry. Serum me-NAM was positively correlated with body mass index and waist circumference and negatively with high-density lipoprotein (P ≤ .03). The correlations remained highly significant in the multivariate adjusted correlation analyses. In men (n = 691), positive correlations between me-NAM and fasting glucose, low-density lipoprotein, liver function, and serum creatinine levels were also observed in both simple and multivariate adjusted correlation analyses. In multiple logistic regression analyses, elevated serum me-NAM was associated with higher risks for overweight/obesity (odds ratios, 2.36 and 5.78; 95% confidence intervals, 1.10-5.08 and 1.78-18.76 for men and women, respectively; P ≤ .03) and diabetes (odds ratios, 1.56 and 1.86; 95% confidence intervals, 1.10-2.22 and 1.05-3.31 for men and women, respectively; P ≤ .03). This first large-scale population study shows that me-NAM, as an indicator of NNMT activity, is strongly associated with obesity and diabetes, supporting NNMT as a potential target for treating obesity and diabetes in humans.

We used a structural interventions framework to analyse the associations between power and condom use among a sample of female sex workers (FSW), and how exposure to a local community mobilization intervention (CMI) affects these associations. Data came from a cross-sectional survey of 812 FSW in the East Godavari district of Andhra Pradesh, India, recruited through respondent-driven sampling. We identified three types of power - collective power, control over work, and economic power, and three dimensions of collective power - collective identity, efficacy, and agency. Multivariate logistic regression analysis was used to analyse the relationship of these three types of power and exposure to a CMI with consistent condom use with clients. A total of 803 respondents exchanged sex with an occasional or regular client in the 7 days before the interview. Multivariate logistic regression shows that control over both the type of sex [adjusted odds ratio (AOR) 1.70, 95% confidence interval (CI) 1.23-2.34] and the amount charged (AOR 1.56, 95% CI 1.12-2.16), and economic dependence (AOR 0.54, 95% CI 0.35-0.83) are associated with consistent condom use as is programme exposure (AOR 2.09, 95% CI 1.48-2.94). The interaction between programme exposure and collective agency was also significant (chi-square 6.62, P = 0.01). Among respondents who reported both programme exposure and high levels of collective agency, the odds ratio of consistent condom use was 2.5 times that of other FSW. A structural interventions framework is useful for understanding HIV risk among FSW. More needs to be done to promote FSW control over work and access to economic resources.

Familial hypercholesterolemia (FH) is characterized by high low-density lipoprotein (LDL) cholesterol with co-dominant transmission and high risk of cardiovascular disease (CVD), although with high variability among subjects. Currently, CVD stratification tools for heterozygous FH (HeFH) are not available. A definition of severe HeFH has been recently proposed by the International Atherosclerosis Society (IAS), but it has not been validated. Our study aims to see clinical characteristics and prevalence of CVD in subjects defined as severe HeFH by IAS criteria. Probable or definite HeFH introduced in the Dyslipidemia Registry of Spanish Arteriosclerosis Society were analyzed by the IAS criteria. Univariate and multivariate analysis was used to assess the association of CVD with the IAS criteria. About 1,732 HeFH cases were analyzed. Severe HeFH had higher prevalence of familial history of CVD, personal history of tendon xanthomas, LDL cholesterol, and CVD than nonsevere HeFH. A total of 656 (77.1%) and 441 (50.1%) of men and women, respectively, fulfilled the IAS criteria of severe HeFH. In the univariate analysis, subjects defined as severe HeFH showed odds ratio 3.016 (95% CI 3.136 to 4.257, p <0.001) for CVD. However, when traditional risk factors were included in the multivariate analysis, only the presence of cholesterol >400 mg/dl had a statistically significant association with CVD odds ratio 8.76 (95% CI 3.90 to 19.69, p <0.001). In conclusion, the IAS definition of severe HeFH is not significantly associated with CVD when adjusted for classic risk factors. Risk stratification in HeFH is an important issue, but the proposed criteria do not seem to solve this problem. Copyright © 2016 Elsevier Inc. All rights reserved.

Individuals affected with mental health conditions, including mood disorders and substance abuse, are at an increased risk of hospital readmission. The objective of this study is to examine whether local health departments' (LHDs) active roles of promoting mental health are associated with reductions in 30-day all-cause readmission rates, a common quality metric. Using datasets linked from multiple sources, including 2012-2013 State Inpatient Databases for the State of Maryland, the National Association of County and City Health Officials Profiles Survey, the Area Health Resource File, and US Census data, we employed multivariate logistic models to examine whether LHDs' active provision of mental health preventive care, mental health services, and health promotion were associated with the likelihood of having any 30-day all-cause readmission. Multivariate logistic regressions showed that LHDs' provision of mental health preventive care, mental health services, and health promotion were negatively associated with the likelihoods of having any 30-day readmission for adults 18-64 years old (odds ratios=0.71-0.82, P<0.001), and adults 65 and above (odds ratios=0.61-0.63, P<0.001, preventive care and services, respectively). These estimated associations were more prominent among individuals with mental illness and/or substance use disorders, African Americans, Medicare, and Medicaid enrollees. Our results suggest that LHDs in Maryland that engage in mental health prevention, promotion, and coordination activities are associated with benefits for residents and for the health care system at large. Additional research is needed to evaluate LHD activities in other states to determine if these results are generalizable.

To evaluate sex differences in diffusion-tensor imaging (DTI) white matter abnormalities after mild traumatic brain injury (mTBI) using tract-based spatial statistics (TBSS) and to compare associated clinical outcomes. The institutional review board approved this study, with waiver of informed consent. DTI in 69 patients with mTBI (47 male and 22 female patients) and 21 control subjects (10 male and 11 female subjects) with normal conventional magnetic resonance (MR) images were retrospectively reviewed. Fractional anisotropy (FA) maps were generated as a measure of white matter integrity. Patients with mTBI underwent serial neurocognitive testing with Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). Correlation between sex, white matter FA values, ImPACT scores, and time to symptom resolution (TSR) were analyzed with multivariate analysis and TBSS. No significant difference in age was seen between males and females (control subjects, P = .3; patients with mTBI, P = .34). No significant difference was seen in initial ImPACT symptom scores (P = .33) between male and female patients with mTBI. Male patients with mTBI had significantly decreased FA values in the uncinate fasciculus (UF) bilaterally (mean FA, 0.425; 95% confidence interval: 0.375, 0.476) compared with female patients with mTBI and control subjects (P < .05), with a significantly longer TSR (P = .04). Multivariate analysis showed sex and UF FA values independently correlated with TSR longer than 3 months (adjusted odds ratios, 2.27 and 2.38; P = .04 and P < .001, respectively), but initial symptom severity did not (adjusted odds ratio, 1.15; P = .35). Relative sparing of the UF is seen in female compared with male patients after mTBI, with sex and UF FA values as stronger predictors of TSR than initial symptom severity.

The aim of this study has been to investigate the factors predisposing to primary or secondary ventricular fibrillation (VF) and the prognosis in Spanish patients with acute myocardial infarction (AMI) during their admission to the intensive care unit or the coronary care unit. A retrospective, observational study. The intensive care units and coronary care units of 119 Spanish hospitals. A retrospective cohort study including all the AMI patients listed in the ARIAM registry (Analysis of Delay in Acute Myocardial Infarction), a Spanish multicenter study. The study period was January 1995 to January 2001. Factors associated with the onset of VF were studied by univariate analysis. Multivariate analysis was used to evaluate the independent factors for the onset of VF and for mortality. A total of 17,761 patients with AMI were included in the study; 964 (5.4%) developed VF (primary in 735 patients, secondary in 229). In multivariate analysis, the variables that continued to show an association with the development of VF were the Killip and Kimball class, peak creatine kinase, APACHE II score, age, and time from the onset of symptoms to the initiation of thrombolysis. The mortality in the patients with any VF was 31.8% (27.8% in patients with primary VF and 49.1% in patients with secondary VF). The development of VF is an independent predictive factor for mortality in patients with AMI, with a crude odds ratio of 5.12 (95% confidence interval, 4.41-5.95) and an adjusted odds ratio of 2.73 (95% confidence interval, 2.12-3.51). Despite the considerable improvement in the treatment of AMI in recent years, the onset of either primary or secondary VF is associated with a poor prognosis. It is usually accompanied by extensive necrosis.

Neurodevelopmental impairment is increasingly recognised as a potentially disabling outcome of CHD and formal evaluation is recommended for high-risk patients. However, data are lacking regarding the proportion of eligible children who actually receive neurodevelopmental evaluation, and barriers to follow-up are unclear. We examined the prevalence and risk factors associated with failure to attend neurodevelopmental follow-up clinic after infant cardiac surgery. Survivors of infant (<1 year) cardiac surgery at our institution (4/2011-3/2014) were included. Socio-demographic and clinical characteristics were evaluated in neurodevelopmental clinic attendees and non-attendees in univariate and multivariable analyses. A total of 552 patients were included; median age at surgery was 2.4 months, 15% were premature, and 80% had moderate-severe CHD. Only 17% returned for neurodevelopmental evaluation, with a median age of 12.4 months. In univariate analysis, non-attendees were older at surgery, had lower surgical complexity, fewer non-cardiac anomalies, shorter hospital stay, and lived farther from the surgical center. Non-attendee families had lower income, and fewer were college graduates or had private insurance. In multivariable analysis, lack of private insurance remained independently associated with non-attendance (adjusted odds ratio 1.85, p=0.01), with a trend towards significance for distance from surgical center (adjusted odds ratio 2.86, p=0.054 for ⩾200 miles). The majority of infants with CHD at high risk for neurodevelopmental dysfunction evaluated in this study are not receiving important neurodevelopmental evaluation. Efforts to remove financial/insurance barriers, increase access to neurodevelopmental clinics, and better delineate other barriers to receipt of neurodevelopmental evaluation are needed.

Racial and ethnic disparities in acute stroke care in the United States have been previously reported. This study investigated possible racial and ethnic disparities in the administration and outcome of recombinant tissue plasminogen activator (rtPA) therapy for acute ischemic stroke in whites, blacks, Hispanics, and Asian/Pacific Islanders. Using the National Inpatient Sample for 2001-2008, we selected patients with a primary diagnosis of acute ischemic stroke who received treatment with rtPA. Patient data were stratified by race (white, black, Hispanic, and Asian/Pacific Islander). We analyzed the association of patient race on rtPA utilization rate, in-hospital morbidity (ie, discharge to long-term facility), intracranial hemorrhage (ICH) rate, and in-hospital mortality. We performed a multivariate logistic regression analysis to determine independent predictors of poor outcomes. White patients had a higher rate of tPA utilization than black and Hispanic patients (2.3% vs 1.8% and 2.0%, respectively; P < .0001 for both groups). There was no difference in the rate of tPA utilization between whites and Asian/Pacific Islanders (2.3% vs 2.2% P = .07). Multivariate analysis of morbidity, mortality, and ICH rates found that Asian/Pacific Islanders had significantly higher rates of mortality (odds ratio, 1.22, 95% confidence interval, 1.03-1.44; P = .02) and ICH (odds ratio, 2.01; 95% confidence interval, 1.91-2.11; P < .0001) compared with whites. rtPA utilization was greater in white and Asian/Pacific Islander patients than in black and Hispanic patients. Asian/Pacific Islander race was associated with increased risk of ICH and mortality after rtPA administration. Copyright © 2013. Published by Elsevier Inc.

To estimate the prevalence of difficult venous access in complex patients with multimorbidity and to identify associated risk factors. In highly complex patients, factors like ageing, the need for frequent use of irritant medication and multiple venous catheterisations to complete treatment could contribute to exhaustion of venous access. A cross-sectional study was conducted. 'Highly complex' patients (n = 135) were recruited from March 2013-November 2013. The main study variable was the prevalence of difficult venous access, assessed using one of the following criteria: (1) a history of difficulties obtaining venous access based on more than two attempts to insert an intravenous line and (2) no visible or palpable veins. Other factors potentially associated with the risk of difficult access were also measured (age, gender and chronic illnesses). Univariate analysis was performed for each potential risk factor. Factors with p < 0·2 were then included in multivariable logistic regression analysis. Odds ratios were also calculated. The prevalence of difficult venous access was 59·3%. The univariate logistic regression analysis indicated that gender, a history of vascular access complications and osteoarticular disease were significantly associated with difficult venous access. The multivariable logistic regression showed that only gender was an independent risk factor and the odds ratios was 2·85. The prevalence of difficult venous access is high in this population. Gender (female) is the only independent risk factor associated with this. Previous history of several attempts at catheter insertion is an important criterion in the assessment of difficult venous access. The prevalence of difficult venous access in complex patients is 59·3%. Significant risk factors include being female and a history of complications related to vascular access. © 2017 John Wiley & Sons Ltd.

T790M, a secondary epidermal growth factor receptor (EGFR) mutation, accounts for approximately 50% of acquired resistance to EGFR-tyrosine kinase inhibitors (TKIs). To facilitate the use of third-generation EGFR-TKIs to potentially overcome T790M-mediated resistance, we evaluated the clinical factors influencing the incidence of T790M mutation. We retrospectively screened patients with non-small-cell lung cancer harboring EGFR mutations with progressive disease who were rebiopsied between January 2013 and December 2016. Factors influencing T790M status were evaluated by univariate and multivariate analysis. Among 131 rebiopsied patients for whom EGFR mutation status was available, 58 (44%) had T790M mutations. Patient characteristics at rebiopsy were not significantly different between T790M-positive and -negative groups, except for surgical history (postsurgery recurrence). Total duration of EGFR-TKI treatment before rebiopsy, TKI-free interval, EGFR-TKI treatment history immediately before rebiopsy, continuation of initial EGFR-TKI beyond progressive disease, progression-free survival after initial TKI treatment, and rebiopsy site (other than fluid samples) significantly influenced T790M status. The incidence of T790M mutation was shown by multivariate analysis to be significantly higher in patients with postsurgery recurrence and total duration of EGFR-TKI treatment ≥ 1 year before rebiopsy (odds ratio, 4.2; 95% confidence interval, 1.3-15.7 and odds ratio, 4.4; 95% confidence interval, 1.1-19.8, respectively). Postsurgery recurrence and longer total duration of EGFR-TKI treatment before rebiopsy may represent useful predictive markers for T790M detection. In patients with these clinical factors, rebiopsies are more recommended to detect T790M mutation. Copyright © 2017 Elsevier Inc. All rights reserved.

To investigate the perioperative complication rates for paraplegic-quadriplegic patients (PQPs) undergoing percutaneous nephrolithotomy (PCNL) as compared with non-PQPs using a standardized method of complication reporting via the Clavien system. Two hundred thirteen consecutive PCNLs performed by a single surgeon were analyzed. There were 31 and 115 patients separated into PQP and non-PQP groups, respectively. Data collection included demographic and clinical factors, as well as perioperative and delayed complications. Complications were organized by the Clavien grade. All- and initial-procedure complications were analyzed. The rate of adverse events for each Clavien grade was calculated, and statistical comparisons were made. The relationship between PQP and complication severity was investigated using univariate and multivariate analyses. There were 38 and 43 initial-procedure complications in the PQP and non-PQP groups, respectively. The rate of adverse events was higher across the spectrum of Clavien grades for the PQP group, specifically grade 1 (48.4% vs 20.2%; P = .002), grade 2 (22.6% vs 5.3%; P = .004), grade 3b (12.9% vs 2.6%; P = .038), grade 4a (6.5% vs 0%), and grade 4b (9.7% vs 1.8%; P = .066). Approximately 51.6% and 31.5% of PQPs and non-PQPs experienced ≥ 1 complications, respectively (odds ratio = 2.34; P = .05). Multivariate analysis demonstrated paraplegia or quadriplegia status to be an independent risk factor for the development of perioperative complications after adjusting for confounding factors (odds ratio = 2.91; P = .040). PCNL complication rates are higher in PQPs compared with non-PQPs. This study is one of the first in PCNL to use a standardized reporting system to highlight high-risk individuals within the stone population. Copyright © 2015 Elsevier Inc. All rights reserved.

BACKGROUND: Extremely preterm infants are at risk for neurodevelopmental impairment (NDI). Early cranial ultrasound (CUS) is usual practice, but near-term brain MRI has been reported to better predict outcomes. We prospectively evaluated MRI white matter abnormality (WMA) and cerebellar lesions, and serial CUS adverse findings as predictors of outcomes at 18 to 22 months’ corrected age. METHODS: Early and late CUS, and brain MRI were read by masked central readers, in a large cohort (n = 480) of infants <28 weeks’ gestation surviving to near term in the Neonatal Research Network. Outcomes included NDI or death after neuroimaging, and significant gross motor impairment or death, with NDI defined as cognitive composite score <70, significant gross motor impairment, and severe hearing or visual impairment. Multivariable models evaluated the relative predictive value of neuroimaging while controlling for other factors. RESULTS: Of 480 infants, 15 died and 20 were lost. Increasing severity of WMA and significant cerebellar lesions on MRI were associated with adverse outcomes. Cerebellar lesions were rarely identified by CUS. In full multivariable models, both late CUS and MRI, but not early CUS, remained independently associated with NDI or death (MRI cerebellar lesions: odds ratio, 3.0 [95% confidence interval: 1.3–6.8]; late CUS: odds ratio, 9.8 [95% confidence interval: 2.8–35]), and significant gross motor impairment or death. In models that did not include late CUS, MRI moderate-severe WMA was independently associated with adverse outcomes. CONCLUSIONS: Both late CUS and near-term MRI abnormalities were associated with outcomes, independent of early CUS and other factors, underscoring the relative prognostic value of near-term neuroimaging.

Preexposure prophylaxis (PrEP) is a promising strategy to prevent human immunodeficiency virus (HIV) infection, especially among high-risk individuals such as seronegative partners; however, many caveats such as the potential risk of sexual disinhibition and noncompliance need to be considered. We explored the sociodemographic and behavioral factors associated with the adoption of PrEP among HIV seronegative men who have sex with men and heterosexual partners. A prepiloted self-administered survey was conducted among seronegative partners in a Ryan White HIV/AIDS Clinic in South Carolina from 2010 to 2011. Bivariate and multivariable analyses were used to explore the data. The survey was completed by 89 seronegative partners. The median age was 42 years (interquartile range 32-50) and a majority was men (56%), black (70%), and heterosexual (74%). A majority (94%) was willing to use PrEP if available; however, 26% of subjects suggested that they would be more likely to have unprotected sex with an HIV-positive partner while using PrEP, and 27% suggested that it would be difficult to take a daily dose of PrEP and consistently use condoms. The multivariable results suggest that the belief that a condom is no longer needed while taking PrEP was more likely among those who did not use a condom during their last sexual intercourse (adjusted odds ratio 7.45; 95% confidence interval 1.57-35.45) and among those with a higher HIV knowledge score (adjusted odds ratio 0.43; 95% confidence interval 0.23-0.78). Overall, these results suggest high acceptability of PrEP among seronegative partners to lower the risk of HIV transmission; however, there is a substantial risk of sexual disinhibition and noncompliance while using PrEP that may be reduced by ongoing education.

The impact of preoperative stable angina pectoris on postoperative cardiovascular outcomes in patients with previous myocardial infarction (MI) who underwent major noncardiac surgery is not well studied. We studied patients with previous MI who underwent elective major noncardiac surgeries within the American College of Surgeons-National Surgical Quality Improvement Program (2005 to 2011). Primary outcome was occurrence of an adverse cardiac event (MI and/or cardiac arrest). Multivariable logistic regression models evaluated the impact of stable angina on outcomes. Of 1,568 patients (median age 70 years; 35% women) with previous MI who underwent major noncardiac surgery, 5.5% had postoperative MI and/or cardiac arrest. Patients with history of preoperative angina had significantly greater incidence of primary outcome compared to those without anginal symptoms (8.4% vs 5%, p = 0.035). In secondary outcomes, reintervention rates (22.5% vs 11%, p <0.001) and length of stay (median 6-days vs 5-days; p <0.001) were also higher in patients with preoperative angina. In multivariable analyses, preoperative angina was a significant predictor for postoperative MI (odds ratio 2.49 [1.20 to 5.58]) and reintervention (odds ratio 2.40 [1.44 to 3.82]). In conclusion, our study indicates that preoperative angina is an independent predictor for adverse outcomes in patients with previous MI who underwent major noncardiac surgery, and cautions against overreliance on predictive tools, for example, the Revised Cardiac Risk Index, in these patients, which does not treat stable angina and previous MI as independent risk factors during risk prognostication.

Few data are available concerning clinical outcomes in patients with Parkinson disease who undergo elective thoracolumbar spine fusion surgery. The goal of this study is to elucidate complication and revision rates after posterior thoracolumbar fusion surgery in patients with Parkinson disease, with a focus on how Parkinson disease modifies these rates. The PearlDiver database (2005-2012) was queried for patients who underwent posterior approach thoracolumbar fusion from 2006 to 2011. Cohorts of patients with a previous diagnosis of Parkinson disease (n = 4816) and without (n = 280,702) were compared. Multivariate analysis that included various comorbidities and demographics was used to calculate effects of Parkinson disease on development of postoperative infection and major medical complications within 90 days and revision surgery within 1 year. For analyses, significance was set at P < 0.001. Major medical complications were observed in 545 patients (11.3%) for 90 days after the index procedure. Postoperative infection was noted in 91 patients (1.9%) within 90 days, and revision surgeries were performed in 250 patients (5.2%) within 1 year. Multivariate analysis showed that Parkinson disease was significantly associated with an increased risk for medical complications (adjusted odds ratio, 1.22; 95% confidence interval, 1.11-1.34; P < 0.001) and revision surgery (adjusted odds ratio, 1.70; 95% confidence interval, 1.49-1.93; P < 0.001), but not postoperative infection (P = 0.02). Patients with Parkinson disease are more likely to require revision surgery and have higher rates of adverse medical events postoperatively. Patients with Parkinson disease should be appropriately selected to ensure favorable clinical outcomes. Copyright © 2016. Published by Elsevier Inc.

Our previous Delphi study identified several audit filters considered sensitive to deviations in prehospital trauma care and potentially useful in conducting performance improvement, a process currently recommended by the American College of Surgeons Committee on Trauma. This study validates 2 of those proposed audit filters. We studied 4,744 trauma patients using the electronic records of the Central Region Trauma registry and Emergency Medical Services (EMS) patient logs for the period January 1, 2002, to December 31, 2004. We studied whether requests by on-scene Basic Life Support (BLS) for Advanced Life Support (ALS) assistance or failure by EMS personnel to record basic patient physiology at the scene was associated with increased in-hospital mortality. We performed multivariate analyses, including a propensity score quintile approach, adjusting for differences in case mix and clustering by hospital. Overall mortality was 6.1%. A total of 28.2% (n = 1,337) of EMS records were missing patient scene physiologic data. Multivariate analysis revealed that patients missing 1 or more measures of patient physiology at the scene had increased risk of death (adjusted odds ratio = 2.15; 95% CI, 1.13 to 4.10). In 17.4% (n = 402) of cases BLS requested ALS assistance. Patients for whom BLS requested ALS had a similar risk of death as patients for whom ALS was initially dispatched (odds ratio = 1.04; 95% CI, 0.51 to 2.15). Failure of EMS to document basic measures of scene physiology is associated with increased mortality. This deviation in care can serve as a sensitive audit filter for performance improvement. The need by BLS for ALS assistance was not associated with increased mortality.

Background: The impact of preoperative radiotherapy on microvascular reconstructive surgery outcome has been a subject of debate. However, data are conflicting and often dependent on local treatment protocols. We have studied the effects of radiotherapy in a unique, single-center setting where a treatment protocol change was undertaken from pre- to postoperative radiotherapy administration for microsurgical head and neck reconstructions. Methods: A cohort study was conducted for 200 consecutive head and neck free flap cases, where 100 were operated on before and 100 after the treatment protocol adjustment in 2006. Only direct cancer reconstructions were included. Complication rates of anastomosis-related (flap necrosis) and flap bed–related (infection, fistula, and wound dehiscence) complications were compared between irradiated and nonirradiated patients. A multivariate analysis was performed to correct for treatment period. Results: One hundred twenty-six patients had received radiotherapy before reconstruction due to cases of cancer recurrence. There were no significant differences in demographic data or risk factors between irradiated and nonirradiated cases. Irradiated cases had a higher rate of both flap loss (9.5% versus 1.4%; P = 0.034) and flap bed–related complications (29% versus 13%; P = 0.014). However, after multivariate analysis, there was only a significant relationship between preoperative irradiation and infection (odds ratio = 2.51; P = 0.033) and fistula formation (odds ratio = 3.13; P = 0.034). Conclusions: The current single-center study clearly indicates that preoperative radiotherapy is a risk factor for both infection and fistula formation, most likely related to an impaired flap bed. We suggest postoperative radiotherapy administration whenever possible for oncological reasons, otherwise proper antibiotic cover and meticulous flap insetting to prevent radiation-related infection and fistula formation.

Background In 2003 the Accreditation Council for Graduate Medical Education mandated work hour restrictions. Violations can results in a residency program being cited or placed on probation. Recurrent violations could results in loss of accreditation. We wanted to determine specific intern and workload factors associated with violation of a specific mandate, the 30-hour duty period requirement. Methods Retrospective review of interns’ performance against the 30-hour duty period requirement during inpatient ward rotations at a pediatric residency program between June 24, 2008 and June 23, 2009. The analytical plan included both univariate and multivariable logistic regression analyses. Results Twenty of the 26 (77%) interns had 80 self-reported episodes of continuous work hours greater than 30 hours. In multivariable analysis, noncompliance was inversely associated with the number of prior inpatient rotations (odds ratio: 0.49, 95% confidence interval (0.38, 0.64) per rotation) but directly associated with the total number of patients (odds ratio: 1.30 (1.10, 1.53) per additional patient). The number of admissions on-call, number of admissions after midnight and number of discharges post-call were not significantly associated with noncompliance. The level of noncompliance also varied significantly between interns after accounting for intern experience and workload factors. Subject to limitations in statistical power, we were unable to identify specific intern characteristics, such as demographic variables or examination scores, which account for the variation in noncompliance between interns. Conclusions Both intern and workload factors were associated with pediatric intern noncompliance with the 30-hour duty period requirement during inpatient ward rotations. Residency programs must develop information systems to understand the individual and experience factors associated with noncompliance and implement appropriate interventions to ensure compliance with the duty hour regulations.

Little is known about the perioperative complication rates of the surgical management of midshaft clavicle nonunions. The purpose of the current study was to report on the perioperative complication rates after surgical management of nonunions and to compare them with complication rates of acute fractures using a population cohort. The American College of Surgeons National Surgical Quality Improvement Program database was queried to identify patients who had undergone open reduction-internal fixation of midshaft clavicle fractures between 2007 and 2013. Patients were stratified by operative indication: acute fracture or nonunion. Patient characteristics and 30-day complication rates were compared between the 2 groups using univariate and multivariate analyses. A total of 1215 patients were included in our analysis. Of these, 1006 (82.8%) were acute midshaft clavicle fractures and 209 (17.2%) were midshaft nonunions. Patients undergoing surgical fixation for nonunion had a higher rate of total complications compared with the acute fracture group (5.26% vs. 2.28%; P = .034). On multivariate analysis, patients with a nonunion were at a >2-fold increased risk of any postsurgical complication (odds ratio, 2.29 [95% confidence interval, 1.05-5.00]; P = .037) and >3-fold increased risk of a wound complication (odds ratio, 3.22 [95% confidence interval, 1.02-10.20]; P = .046) compared with acute fractures. On the basis of these findings, patients undergoing surgical fixation for a midshaft clavicle nonunion are at an increased risk of short-term complications compared with acute fractures. This study provides additional information to consider in making management decisions for these common injuries. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

To evaluate the effects of maternal pre-pregnancy body mass index (pre-BMI) and gestational weight gain (GWG) on neonatal birth weight (NBW) in the population of Chinese healthy pregnant women, attempting to guide weight control in pregnancy. A retrospective cohort study of 3772 Chinese women was conducted. The population was stratified by maternal pre-BMI categories as underweight (<18.5 kg/m 2 ), normal weight (18.5-23.9 kg/m 2 ), overweight (24.0-27.9 kg/m 2 ), and obesity (≥28.0 kg/m 2 ). The NBW differences were tested among the four groups, and then deeper associations among maternal pre-BMI, GWG, and NBW were investigated by multivariate analysis. NBW increased significantly with the increase of maternal pre-BMI level (P<0.05), except overweight to obesity (P>0.05). The multivariate analysis showed that both pre-BMI and GWG were positively correlated with NBW (P<0.05). Compared with normal pre-BMI, underweight predicted an increased odds ratio of small-for-gestational-age (SGA) and decreased odds ratio for macrosomia and large-for-gestational-age (LGA), and the results were opposite for overweight. With the increase of GWG, the risk of SGA decreased and the risks of macrosomia and LGA increased. In addition, in different pre-BMI categories, the effects of weight gain in the first trimester on NBW were different (P<0.05). NBW is positively affected by both maternal pre-BMI and GWG, extreme pre-BMI and GWG are both associated with increased risks of abnormal birth weight, and maternal pre-BMI may modify the effect of weight gain in each trimester on NBW. A valid GWG guideline for Chinese women is an urgent requirement, whereas existing recommendations seem to be not very suitable for the Chinese.

Cerebral malaria (CM) causes a rapidly developing coma, and remains a major contributor to morbidity and mortality in malaria-endemic regions. This study sought to determine the relationship between cerebrospinal fluid (CSF) Plasmodium falciparum histidine rich protein-2 (PfHRP-2) and clinical, laboratory and radiographic features in a cohort of children with retinopathy-positive CM. Patients included in the study were admitted (2009-2013) to the Pediatric Research Ward (Queen Elizabeth Central Hospital, Blantyre, Malawi) meeting World Health Organization criteria for CM with findings of malarial retinopathy. Enzyme-linked immunosorbent assay was used to determine plasma and CSF PfHRP-2 levels. Wilcoxon rank-sum tests and multivariable logistic regression analysis assessed the association of clinical and radiographic characteristics with the primary outcome of death during hospitalization. In this cohort of 94 patients, median age was 44 (interquartile range 29-62) months, 53 (56.4%) patients were male, 6 (7%) were HIV-infected, and 10 (11%) died during hospitalization. Elevated concentrations of plasma lactate (p = 0.005) and CSF PfHRP-2 (p = 0.04) were significantly associated with death. On multivariable analysis, higher PfHRP-2 in the CSF was associated with death (odds ratio 9.00, 95% confidence interval 1.44-56.42) while plasma PfHRP-2 was not (odds ratio 2.05, 95% confidence interval 0.45-9.35). Elevation of CSF, but not plasma PfHRP-2, is associated with death in this paediatric CM cohort. PfHRP-2 egress into the CSF may represent alteration of blood brain barrier permeability related to the sequestration of parasitized erythrocytes in the cerebral microvasculature.

There are limited data regarding clinical and treatment factors associated with radiation pneumonitis (RP) in patients receiving taxane-based trimodality therapy for esophageal cancer. The purpose of this study was to identify predictors of RP in patients undergoing trimodality therapy. We retrospectively reviewed patients undergoing chemoradiation followed by esophagectomy between 2006 and 2011. The association between clinical and dosimetric factors with RP was assessed using χ 2 test and Mann-Whitney U test. Multivariable regression was used to assess the relationship between grade 2+ RP and clinical/dosimetric factors. Receiver operator curves were generated to identify threshold doses for RP. A total of 139 patients were included; 19 (13.7%) patients experienced grade 2+ RP. Patients with upper/middle thoracic tumors (P = .038) and receiving higher radiation doses (P = .038) were more likely to develop grade 2+ RP. There was no association between taxane-based therapy and grade 2+ RP (P = .728). The percent volume of lung receiving 5 Gy (V5; P < .001), 10 Gy (P < .001), 20 Gy (V20; P < .001), and 30 Gy (P < .001) was associated with an increased risk of grade 2+ RP. On multivariable regression, the lung V5 (odds ratio, 1.101; 95% confidence interval, 1.1014-1.195) and V20 (odds ratio, 1.149; 95% confidence interval, 1.1015-1.301) remained associated with grade 2+ RP. A V5 ≤65% and V20 ≤25% were identified as optimal thresholds for increased grade 2+ RP. Dosimetric parameters are strong predictors of symptomatic RP in patients undergoing trimodality therapy for esophageal cancer. Mitigating the risk of RP in these patients should be an important consideration during treatment planning. Copyright © 2016 American Society for Radiation Oncology. Published by Elsevier Inc.

To evaluate 30-day and 90-day mortality after major pulmonary resection for lung cancer including the relationship to hospital volume. Major lung resections from 2007 to 2011 were identified in the National Cancer Data Base. Mortality was compared according to annual volume and demographic and clinical covariates using univariate and multivariable analyses, and included information on comorbidity. Statistical significance (P<.05) and 95% confidence intervals were assessed. There were 124,418 major pulmonary resections identified in 1233 facilities. The 30-day mortality rate was 2.8%. The 90-day mortality rate was 5.4%. Hospital volume was significantly associated with 30-day mortality, with a mortality rate of 3.7% for volumes less than 10, and 1.7% for volumes of 90 or more. Other variables significantly associated with 30-day mortality include older age, male sex, higher stage, pneumonectomy, a previous primary cancer, and multiple comorbidities. Similar results were found for 90-day mortality rates. In the multivariate analysis, hospital volume remained significant with adjusted odds ratios of 2.1 (95% confidence interval [CI], 1.7-2.6) for 30-day mortality and 1.3 (95% CI, 1.1-1.6) for conditional 90-day mortality for the hospitals with the lowest volume (<10) compared with those with the highest volume (>90). Hospitals with a volume less than 30 had an adjusted odds ratio for 30-day mortality of 1.3 (95% CI, 1.2-1.5) compared with those with a volume greater than 30. Mortality at 30 and 90 days and hospital volume should be monitored by institutions performing major pulmonary resection and benchmarked against hospitals performing at least 30 resections per year.

Introduction Randomized studies have shown that bortezomib (BTZ) can be given weekly via intravenous (IV) route or twice weekly via subcutaneous (SC) route with lower neuropathy risk and no loss of anti-myeloma efficacy compared to original standard IV twice weekly schedule. Weekly SC should therefore yield the best therapeutic index and is widely used but has not been compared to established administration schedules in the context of a clinical trial. Methods Comprehensive electronic medical record review was done for disease control and neuropathy symptoms of 344 consecutive patients who received their first BTZ-containing regimen for myeloma or AL amyloidosis before or after we changed to SC weekly in December 2010. Univariate and multivariable analyses were carried out that adjusted for age, underlying disease, concurrently used anticancer agents, underlying conditions predisposing to neuropathy, and number of prior regimens compared SC weekly to other schedules. Results Fifty-three patients received BTZ SC weekly, 17 SC twice weekly, 127 IV weekly and 147 IV twice weekly. Risk for neuropathy of any grade was higher with other schedules compared to SC weekly (44.3% vs. 26.9%, p = 0.001) while response rate was similar (72.1% vs. 76.6%, respectively, p = 0.15). Multivariable analyses upheld higher neuropathy risk (Odds ratio 2.45, 95% CI 1.26–4.76, p = 0.008) while the likelihood of not achieving a response (= partial response or better) was comparable (Odds ratio 1.25, 95% CI 0.58–2.71, p = 0.56) for other schedules compared to SC weekly, respectively. Lower neuropathy risk translated into longer treatment duration when BTZ was started SC weekly (p = 0.001). Conclusions Weekly SC BTZ has activity comparable to other schedules and causes low rates of neuropathy. PMID:28278302

To investigate the relationship between vitamin D and glaucoma. This retrospective, cross-sectional study included subjects who underwent a health screening at the Health Screening Center of Kangbuk Samsung Hospital from August 2012 to July 2013. All fundus photographs were reviewed by ophthalmologists. The ophthalmologists determined if an eye was glaucomatous based on the criteria set forth by the International Society of Geographical and Epidemiological Ophthalmology and by the appearance of the retinal nerve fiber layer and optic disc. If the subjects previously underwent an ophthalmologic examination, they were enrolled based on the documented history. In addition to fundus photographs, each participant underwent a systemic examination including blood sampling and sociodemographic and behavioral questionnaires. The subjects were divided into five groups according to serum 25-hydroxyvitamin D (25(OH)D) level. Multivariate logistic regression models were constructed to assess possible associations between elevated glaucoma risk and systemic factors with a p < 0.2 on univariate analysis. Of the 169,208 subjects older than 20 years, 123,331 were eligible for the study. There was no difference in the prevalence of glaucoma according to quintile of serum 25(OH)D level based on sex ( p = 0.412 for males, p = 0.169 for females). According to the multivariable-adjusted logistic analysis, the odds ratio of glaucoma for the fourth quintile was significantly lower than that of the first quintile in females (odds ratio, 0.713; 95% confidence interval, 0.520 to 0.979). Lower 25(OH)D level was significantly associated with an elevated risk of glaucoma in females compared with higher 25(OH)D level. Further evaluation is needed to investigate the relationship between glaucoma and vitamin D.

As variation in care has previously been linked to quality, we aimed to describe variations in inflammatory bowel diseases care by gastroenterology (GI) practice setting. We performed a cross-sectional study within the Crohn's and Colitis Foundation of America Partners and used bivariate analyses to compare patient characteristics by GI practice setting (GI-academic [GIA], GI-private, or GI-other). Regression models were used to describe the effects of provider type on steroid use, disease activity, and the quality of life. The study included 12,083 patients with inflammatory bowel diseases (7576 with Crohn's disease [CD] and 4507 with ulcerative colitis [UC]). Nearly 95% reported visiting a GI provider annually. Also, CD patients seen by GIA were younger, better educated, used less 5-aminosalicylate agents, and had higher biologic and immunomodulator use (P < 0.001 for all). On multivariate analysis of CD patients, GIA used less steroids when compared with GI-private (odds ratio, 0.84; 95% confidence interval, 0.67-1.06) or GI-other (odds ratio, 0.66; 95% confidence interval, 0.49-0.89). GIA patients were more likely to be in remission, have flu vaccine, and have better quality of life. UC patients seen by GIA were younger, had more hospitalizations, and previous surgery (P < 0.001 for all). No differences existed for steroid use, remission, flu vaccine, or quality of life for UC care on bivariate or multivariate analyses. Significant variations in care patterns and quality measures exist for CD across GI provider types, without similar variation in UC care. Interventions to reduce variations in care could improve the quality of care in CD.

Background Traditionally, the delivery of dedicated neurocritical care (NCC) occurs in distinct NCC units and is associated with improved outcomes. Institution-specific logistical challenges pose barriers to the development of distinct NCC units; therefore, we developed a consultancy NCC service coupled with the implementation of invasive multimodal neuromonitoring, within a medical-surgical intensive care unit. Our objective was to evaluate the effect of a consultancy NCC program on neurologic outcomes in severe traumatic brain injury patients. We conducted a single-center quasi-experimental uncontrolled pre- and post-NCC study in severe traumatic brain injury patients (Glasgow Coma Scale ≤8). The NCC program includes consultation with a neurointensivist and neurosurgeon and multimodal neuromonitoring. Demographic, injury severity metrics, neurophysiologic data, and therapeutic interventions were collected. Glasgow Outcome Scale (GOS) at 6 months was the primary outcome. Multivariable ordinal logistic regression was used to model the association between NCC implementation and GOS at 6 months. A total of 113 patients were identified: 76 pre-NCC and 37 post-NCC. Mean age was 39 years (standard deviation [SD], 2) and 87 of 113 (77%) patients were male. Median admission motor score was 3 (interquartile ratio, 1-4). Daily mean arterial pressure was higher (95 mmHg [SD, 10]) versus (88 mmHg [SD, 10], p<0.001) and daily mean core body temperature was lower (36.6°C [SD, 0.90]) versus (37.2°C [SD, 1.0], p=0.001) post-NCC compared with pre-NCC, respectively. Multivariable regression modelling revealed the NCC program was associated with a 2.5 increased odds (odds ratios, 2.5; 95% confidence interval, 1.1-5.3; p=0.022) of improved 6-month GOS. Implementation of a NCC program is associated with improved 6 month GOS in severe TBI patients.

Recently it has been recommended that all cirrhotic patients without previous variceal hemorrhage undergo endoscopic screening to detect varices and that those with large varices should be treated with beta-blockers (American College of Gastroenterology guidelines). However, endoscopic screening only of patients at highest risk for varices may be the most cost effective. Ninety-eight patients without a history of variceal hemorrhage underwent esophagogastroduodenoscopy as part of a liver transplant evaluation. Univariate/multivariate analysis was used to evaluate associations between the presence of varices and patient characteristics including etiology of liver disease, Child-Pugh class, physical findings (spider angiomata, splenomegaly, and ascites), encephalopathy, laboratory parameters (prothrombin time, albumin, bilirubin, BUN, creatinine, and platelets), and abdominal ultrasound findings (portal vein diameter/flow, splenomegaly, and ascites). The causes of cirrhosis among the 67 men and 31 women (mean age, 48 yr) included 28% Hepatitis C/alcoholism, 25% Hepatitis C, 13% alcoholism, 9% primary sclerosing cholangitis/primary biliary cirrhosis, 9% cryptogenic, 6% Hepatitis B, 1% Hepatitis B and C, and 9% other. Patients were Child-Pugh class A 34%, B 51%, and C 15%. Endoscopic findings included esophageal varices in 68% of patients (30% were large), gastric varices in 15%, and portal hypertensive gastropathy in 58%. Platelet count <88,000 was the only parameter identified by univariate/multivariate analysis (p < 0.05) as associated with the presence of large esophageal varices (odds ratio 5.5; 95% confidence interval 1.8-20.6) or gastric varices (odds ratio 5; 95% confidence interval 1.4-23). Platelet count <88,000 is associated with the presence of esophagogastric varices. A large prospective study is needed to verify and validate these findings and may allow identification of a group of patients who would most benefit from endoscopic screening for varices.

The aim of this study was to investigate the impact of wait days (WDs) on missed outpatient MRI appointments across different demographic and socioeconomic factors. An institutional review board-approved retrospective study was conducted among adult patients scheduled for outpatient MRI during a 12-month period. Scheduling data and demographic information were obtained. Imaging missed appointments were defined as missed scheduled imaging encounters. WDs were defined as the number of days from study order to appointment. Multivariate logistic regression was applied to assess the contribution of race and socioeconomic factors to missed appointments. Linear regression was performed to assess the relationship between missed appointment rates and WDs stratified by race, income, and patient insurance groups with analysis of covariance statistics. A total of 42,727 patients met the inclusion criteria. Mean WDs were 7.95 days. Multivariate regression showed increased odds ratio for missed appointments for patients with increased WDs (7-21 days: odds ratio [OR], 1.39; >21 days: OR, 1.77), African American patients (OR, 1.71), Hispanic patients (OR, 1.30), patients with noncommercial insurance (OR, 2.00-2.55), and those with imaging performed at the main hospital campus (OR, 1.51). Missed appointment rate linearly increased with WDs, with analysis of covariance revealing underrepresented minorities and Medicaid insurance as significant effect modifiers. Increased WDs for advanced imaging significantly increases the likelihood of missed appointments. This effect is most pronounced among underrepresented minorities and patients with lower socioeconomic status. Efforts to reduce WDs may improve equity in access to and utilization of advanced diagnostic imaging for all patients. Copyright © 2018. Published by Elsevier Inc.

Limited data support the notion that lipid ratios are risk factors for nonalcoholic fatty liver disease (NAFLD). We evaluated the association between lipid ratios and NAFLD. This was a large population, cross-sectional, retrospective study. Data on NAFLD severity, blood pressure, fasting glucose, total cholesterol (TC), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) levels were obtained from 44,767 examinees at single health checkup center. The enrollees were stratified into four subgroups based on their TC/HDL-C and TG/HDL-C ratios. We used multivariate analyses to evaluate the odds between lipid ratios and NAFLD. The prevalence rate of fatty liver in this study was 53.76%. In the baseline subgroup with the lowest TC/HDL-C and TG/HDL-C ratios, the prevalence of NAFLD, hypertension, and diabetes was lower than that of the other three subgroups. Patients with higher lipid ratios had a significantly greater risk for advanced NAFLD. Adults with high TC/HDL-C or TG/HDL-C ratios, or both, have a greater risk for NAFLD, especially advanced NAFLD.

We sought to identify factors associated with condom use during anal intercourse among self-identified human immunodeficiency virus-negative gay, bisexual, and other men who have sex with men (GBM) in Vancouver, Canada following "treatment as prevention" (TasP) scale-up in 2010. Sexually active GBM were recruited using respondent-driven sampling from 2012 to 2014. We analyzed participants' most recent sexual encounter with up to their last 5 sexual partners within the past 6 months. In addition to individual- and event-level explanatory factors, we assessed potential associations with TasP awareness, TasP-related prevention practice (viral load sorting), and TasP-related attitudes (human immunodeficiency virus treatment optimism). Accounting for clustering at the respondent-driven sampling chain-level and participant-level, factors associated with event-level condom use versus nonuse were determined using a multivariable generalized linear mixed model built using backward selection and AIC minimization. Of 513 participants, 436 GBM (85%) reported a total of 1196 anal sex events with 56% condom use. The proportion of condom-protected sexual events decreased monthly over the study period (odds ratio [OR], 0.95 per month, 95% confidence interval [CI], 0.92-0.98). The TasP practices and attitudes were significantly associated with lower odds of condom use at the univariate level, but were no longer significant at multivariate level. In the multivariable model, event-level partner methamphetamine use (adjusted OR [aOR], 0.18; 95% CI, 0.06-0.58), frequency of recent anal intercourse with that partner (aOR, 0.97 per act; 95% CI, 0.95-0.98) and time since first sex with that partner (aOR, 0.97 per 6 months; 95% CI, 0.95-0.99) were associated with lower odds of condom use, whereas event-level participant alcohol use (aOR, 1.41; 95% CI, 1.01-1.98) and no planned future sex with that partner (aOR, 1.56; 95% CI, 1.08-2.27) were associated with greater odds of condom use. Event-level receptive-only (aOR, 2.10; 95% CI, 1.38-3.20) or insertive-only (aOR, 2.53; 95% CI, 1.64-3.90) sexual positions were associated with greater odds of condom use compared with reporting both positions. The TasP-related factors were not the most salient predictors of GBM's condom use. Health promotion must consider associations between condomless anal sex and substance use and relational factors.

We compared the odds of vitamin D deficiency in three chronic diseases: systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and type 2 diabetes (T2DM), adjusting for medications, demographics, and laboratory parameters, common to all three diseases. We also designed multivariate models to determine whether different factors are associated with vitamin D deficiency in different racial/ethnic groups. We identified all patients with non-overlapping diagnoses of SLE, RA, and T2DM, with 25-hydroxyvitamin D (25OHD) levels measured between 2000 and 2009. Vitamin D deficiency was defined as 25OHD levels <20 ng/ml, based on previously established definitions. Race/ethnicity was analyzed as African-American non-Hispanic (African-American), Hispanic non-African-American (Hispanic), and Other based on self report. We included 3,914 patients in the final analysis: 123 SLE, 100 RA, and 3,691 T2DM. Among African-Americans the frequency of vitamin D deficiency was 59% in SLE, 47% in RA, and 67% in T2DM. Among Hispanics the frequency of vitamin D deficiency was 67% in SLE, 50% in RA, and 59% in T2DM. Compared with the SLE group, the adjusted odds ratio of vitamin D deficiency was 1.1, 95% CI (0.62, 2.1) in the RA group, and 2.0, 95% CI (1.3, 3.1) in the T2DM group. In the multivariate analysis, older age, higher serum calcium and bisphosphonate therapy were associated with a lower odds of vitamin D deficiency in all three racial/ethnic groups: 1,330 African-American, 1,257 Hispanic, and 1,100 Other. T2DM, serum creatinine, and vitamin D supplementation were associated with vitamin D deficiency in some, but not all, racial/ethnic groups. Vitamin D deficiency is highly prevalent in our patients with SLE, RA, and T2DM. While the odds of vitamin D deficiency are similar in RA and SLE patients in a multivariate analysis, T2DM patients have much higher odds of being vitamin D deficient. Different demographic and laboratory factors may be associated with vitamin D deficiency within different racial/ethnic groups. Therefore, disease-specific and race/ethnicity-specific definitions of vitamin D deficiency need to be established in future studies in order to define goals of vitamin D replacement in patients with autoimmune and non-autoimmune chronic diseases.

Although hypothermia and barbiturates improve neurologic outcomes in animal temporary focal ischemia models, the clinical efficacy of these interventions during temporary occlusion of the cerebral vasculature during intracranial aneurysm surgery (temporary clipping) is not established. A post hoc analysis of patients from the Intraoperative Hypothermia for Aneurysm Surgery Trial who underwent temporary clipping was performed. Univariate and multivariate logistic regression methods were used to test for associations between hypothermia, supplemental protective drug, and short- (24-h) and long-term (3-month) neurologic outcomes. An odds ratio more than 1 denotes better outcome. Patients undergoing temporary clipping (n = 441) were assigned to intraoperative hypothermia (33.3 degrees +/- 0.8 degrees C, n = 208) or normothermia (36.7 degrees +/- 0.5 degrees C, n = 233), with 178 patients also receiving supplemental protective drug (thiopental or etomidate) during temporary clipping. Three months after surgery, 278 patients (63%) had good outcome (Glasgow Outcome Score = 1). Neither hypothermia (P = 0.847; odds ratio = 1.043, 95% CI = 0.678-1.606) nor supplemental protective drug (P = 0.835; odds ratio = 1.048, 95% CI = 0.674-1.631) were associated with 3-month Glasgow Outcome Score. The effect of supplemental protective drug did not significantly vary with temperature. The effects of hypothermia and protective drug did not significantly vary with temporary clip duration. Similar findings were made for 24-h neurologic status and 3-month Neuropsychological Composite Score. In the Intraoperative Hypothermia for Aneurysm Surgery Trial, neither systemic hypothermia nor supplemental protective drug affected short- or long-term neurologic outcomes of patients undergoing temporary clipping.

Cross-sectional. To examine whether 3 types of chronic pain are associated with absenteeism and with the number of days absent from work in the general population of Spain. Chronic pain has been associated with absenteeism, but most of the evidence is based on unadjusted analyses and on specific professional categories. A cross-sectional analysis was performed on the basis of data of 8283 Spanish workers. Chronic pain was ascertained from self-reported information on frequent symptoms of pain in the low back and neck and/or migraine in the last 12 months. Absenteeism was defined as missing at least 1 day from work because of health problems. Multivariate regression models were adjusted for the main confounders. Health-related absenteeism was reported by 27.8% of subjects. The prevalence of chronic pain was reported to be 12.3% in the neck, 14.1% in the low back, and 10.3% migraine. In adjusted analyses, absenteeism was associated with chronic neck pain (odds ratio: 1.20; 95% confidence interval [CI], 1.02-1.40), low back pain (odds ratio: 1.22; 95% CI, 1.06-1.42), and migraine (odds ratio: 1.22; 95% CI, 1.04-1.44). These associations were strongest in younger (18-34 yr) rather than in older workers. Furthermore, those who reported frequent pain in the neck and low back were 44% more likely to be absent for more than 30 days in the past year than those who did not report these symptoms. Spanish workers with chronic pain were more likely to be absent from work and to stay absent from work for longer. These associations are independent of sociodemographic characteristics, occupation, lifestyle, health status, and analgesics use. N/A.

The goal of this study was to investigate patterns of ambulatory antibiotic use and to identify factors associated with broad-spectrum antibiotic prescribing for pediatric urinary tract infections (UTIs). We examined antibiotics prescribed for UTIs for children aged younger than 18 years from 1998 to 2007 using the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey. Amoxicillin-clavulanate, quinolones, macrolides, and second- and third-generation cephalosporins were classified as broad-spectrum antibiotics. We evaluated trends in broad-spectrum antibiotic prescribing patterns and performed multivariable logistic regression to identify factors associated with broad-spectrum antibiotic use. Antibiotics were prescribed for 70% of pediatric UTI visits. Trimethoprim-sulfamethoxazole was the most commonly prescribed antibiotic (49% of visits). Broad-spectrum antibiotics were prescribed one third of the time. There was no increase in overall use of broad-spectrum antibiotics (P = .67); however, third-generation cephalosporin use doubled from 12% to 25% (P = .02). Children younger than 2 years old (odds ratio: 6.4 [95% confidence interval: 2.2-18.7, compared with children 13-17 years old]), females (odds ratio: 3.6 [95% confidence interval: 1.6-8.5]), and temperature ≥ 100.4°F (odds ratio: 2.9 [95% confidence interval: 1.0-8.6]) were independent predictors of broad-spectrum antibiotic prescribing. Race, physician specialty, region, and insurance status were not associated with antibiotic selection. Ambulatory care physicians commonly prescribe broad-spectrum antibiotics for the treatment of pediatric UTIs, especially for febrile infants in whom complicated infections are more likely. The doubling in use of third-generation cephalosporins suggests that opportunities exist to promote more judicious antibiotic prescribing because most pediatric UTIs are susceptible to narrower alternatives.

Among men with newly diagnosed prostate cancer, prostate-specific antigen (PSA) levels are higher and the cancer stage more advanced for African Americans than for whites. An earlier study found that after adjustment for literacy, race was no longer a significant predictor of advanced stage at presentation. We investigated whether, after adjusting for literacy, race was a significant independent predictor of greater PSA levels among men with newly diagnosed prostate cancer. Consecutive patients with newly diagnosed prostate cancer from four outpatient care facilities in Chicago were interviewed and given a literacy assessment (n = 308). The PSA level at diagnosis was obtained from the medical charts. Logistic regression models were used to identify predictors of high PSA levels (greater than 20 ng/mL) at presentation. African-American men were three times more likely to have low literacy skills (sixth grade or less: 22.9% versus 7.1%; P <0.001) than were white men. In turn, men with low literacy skills were more than twice as likely to have a PSA level greater than 20 ng/mL at diagnosis (33.3% versus 13.5%; P = 0.009). On multivariate analyses, significant predictors of high PSA levels included low literacy (adjusted odds ratio 2.5, 95% confidence interval 1.5 to 4.2) and older age (age 65 to 74 years, adjusted odds ratio 2.6, 95% confidence interval 2.1 to 3.1 versus older than 74 years, adjusted odds ratio 3.4, 95% confidence interval 1.8 to 6.6), but not African-American race. In the current era in which PSA testing is common, low literacy may be an important and potentially overlooked factor associated with higher PSA levels at prostate cancer diagnosis among African-American and white men.

Many intercountry adoptees are reaching adolescence in western Europe and the USA, and the mental health and social adjustment of these individuals as adolescents and young adults has now become an important issue. We aimed to assess mental health disorders and social maladjustment in adolescence and young adulthood in intercountry adoptees in Sweden. Our data was obtained from the Swedish national registers for the cohort born in 1970-79. We used multivariate Cox's regression models of person-years to compare indicators of suicide death (1986-95), court sentences (1986-93), and discharges for psychiatric illness, suicide attempts, and substance abuse (1987-94) in 11,320 intercountry adoptees with 2343 Swedish-born siblings, 4006 immigrant children, and a general population of 853 419 Swedish-born residents. After adjustment for major sociodemographic confounders, intercountry adoptees were more likely than other Swedish-born children to die from suicide (odds ratio 3.6, 95% CI 2.1-5.9); attempt suicide (3.6, 3.1-4.2); be admitted for a psychiatric disorder (3.2, 2.9-3.6), drug abuse (5.2, 2.9-9.3) or alcohol abuse (2.6, 2.0-3.3); or to commit a crime (1.6, 1.5-1.7). Siblings in adoptive homes had lower odds ratios for most outcomes than did adoptees, whereas adoptees and immigrant children had much the same odds ratios. Adoptees in Sweden have a high risk for severe mental health problems and social maladjustment in adolescence and young adulthood. We advise professionals to give appropriate consideration to the high risk of suicide in patients who are intercountry adoptees.

To describe the clinical characteristics and outcome of patients admitted to pediatric intensive care with influenza A (pH1N1) 2009 in Argentina. Retrospective observational study. Thirteen pediatric intensive care units in Argentina. One hundred and forty-two patients with confirmed or suspected influenza A (H1N1). None. We included 142 critically ill patients. The median age was 19 months (range, 2-110 months) with 39% of the patients <24 months of age. Ninety-nine patients (70%) had an underlying disease. Influenza A (pH1N1) 2009 infection was confirmed in 90 patients and the remaining 52 had a positive direct immunofluorescence assay for influenza A. The median length of stay in the pediatric intensive care unit was 12 days (range, 2-52 days). One hundred eighteen patients (83%) received invasive mechanical ventilation and 19 patients were treated with noninvasive ventilation; however, seven of the patients receiving noninvasive ventilation later needed mechanical ventilation. Sixty-eight patients died (47%) with the most frequent cause refractory hypoxemia. Multivariate logistic regression analysis showed that age <24 months (odds ratio, 2.87; 2.35-3.93), asthma (odds ratio, 1.34; 1.20-2.91), and respiratory coinfection with respiratory syncytial virus (odds ratio, 2.92; 1.20-4.10) were associated with higher mortality. As expected, mechanical ventilation and treatment with inotropes were also associated with increased mortality. The mortality of children admitted to the pediatric intensive care unit with 2009 pH1N1 influenza was high (47%) in our population. Age <24 months, asthma, respiratory coinfection, need of mechanical ventilation, and treatment with inotropes were predictors of poorer outcome.

BACKGROUND. Silent peptic ulcer has been considered to be associated with nonsteroidal anti-inflammatory drug (NSAID). The recent studies have reported no relationship between them. AIM. We attempted to investigate an association between asymptomatic peptic ulcer and NSAID in Korean adults. METHODS. The subjects were enrolled from participants visiting Myongji Hospital for health examination program of the Korean National Health Insurance Corporation. The questionnaires were designed to investigate individual medical information and gastroduodenal symptoms. RESULTS. From May 2005 to March 2009, 5459 participants were enrolled and 299 participants were excluded. Of 5160 participants, 3144 (60.9%) participants were asymptomatic and 424 (8.2%) participants had peptic ulcer. Among 3144 asymptomatic participants, NSAID-taking participants had the odds ratio of 1.4 [95% confidence interval (CI): 0.7-2.6, p = 0.339] for the risk of peptic ulcer. Among 424 peptic ulcer patients, 247 (58.3%) were asymptomatic. They had lower prevalence of NSAID use (4.9% vs. 14.7%). The asymptomatic gastric ulcer patients had smaller size and more frequent healing stage than the symptomatic gastric ulcer patients. In multivariable analysis of 424 peptic ulcer patients, NSAID patients had the odds ratio of 0.249 (95%CI: 0.115-0.536, p < 0.05) for asymptomatic peptic ulcer. In subgroup analysis of 284 gastric ulcer patients, NSAID-taking patients had the odds ratio of 0.263 (95% CI: 0.105-0.657, p = 0.004) for asymptomatic peptic ulcer. CONCLUSION. NSAID has an inverse association with asymptomatic patients with gastric peptic ulcer, but has no association with gastroduodenal symptoms in duodenal ulcer patients. These suggest that NSAID may be associated with gastroduodenal symptoms rather than masking symptoms, at least in gastric ulcer patients.

To evaluate whether administration of nitroglycerin through the sheath at the end of a transradial procedure might preserve the patency of the radial artery. Despite the increasing acceptance of transradial approach, radial artery occlusion (RAO) continues to be a vexing problem of transradial access and limits utility of the radial artery as an access site in the future. We conducted a multicenter, prospective, randomized, placebo-controlled, operator-blinded trial and enrolled 1,706 patients who underwent transradial catheterization in three experienced radial centers. Patients were randomized to receive either 500 µg nitroglycerin (n=853) or placebo (n=853), given intra-arterially through the sheath at the end of the radial procedure. The primary outcome was the incidence of RAO as confirmed by absence of antegrade flow at one day after the transradial procedure evaluated by duplex ultrasound of the radial artery. The use of nitroglycerin, as compared with placebo, reduced the risk of the primary outcome [8.3% vs. 11.7%; odds ratio, 0.62; 95% confidence interval (CI), 0.44-0.87; P=0.006]. From a multivariable analysis, duration of hemostasis was a predictor of RAO (odds ratio, (odds ratio, 3.11; 95% CI, 1.66 to 5.82; P<0.001). There were no significant differences between the groups with respect to the sheath size (P=0.311), number of puncture attempts (P=0.941), duration of hemostasis (P=0.379) and procedural time (P=0.095). The administration of nitroglycerin at the end of a transradial catheterization, reduced the incidence of RAO, examined 1 day after the radial procedure by ultrasound. Postprocedural/prehemostasis pharmacologic regimens may represent a novel target for further investigation to reduce RAO. © 2014 Wiley Periodicals, Inc.

Ethnic minority service users with schizophrenia and schizoaffective disorders may experience inequalities in care. There have been no recent studies assessing access to evidence-based treatments for psychosis amongst the main ethnic minority groups in the UK. Data from nationally representative surveys from England and Wales, for 10,512 people with a clinical diagnosis of schizophrenia or schizoaffective disorders, were used for analyses. Multi-level multivariable logistic regression analyses were used to assess ethnic minority inequalities in access to pharmacological treatments, psychological interventions, shared decision making and care planning, taking into account a range of potential confounders. Compared with white service users, black service users were more likely prescribed depot/injectable antipsychotics (odds ratio 1.56 (95% confidence interval 1.33-1.84)). Black service users with treatment resistance were less likely to be prescribed clozapine (odds ratio 0.56 (95% confidence interval 0.39-0.79)). All ethnic minority service users, except those of mixed ethnicity, were less likely to be offered cognitive behavioural therapy, compared to white service users. Black service users were less likely to have been offered family therapy, and Asian service users were less likely to have received copies of care plans (odds ratio 0.50 (95% confidence interval 0.33-0.76)), compared to white service users. There were no clinician-reported differences in shared decision making across each of the ethnic minority groups. Relative to white service users, ethnic minority service users with psychosis were generally less likely to be offered a range of evidence-based treatments for psychosis, which included pharmacological and psychological interventions as well as involvement in care planning.

Furthermore, we explored whether these factors explained the race disparity in STIs. We conducted a cross-sectional analysis of wave 3 of the National Longitudinal Study of Adolescent Health collected in 2001 to 2002. Young adult participants (aged 18-26 years) provided urine specimens that were tested for chlamydia, gonorrhea, and trichomoniasis infection. Estimates of the association between AI with any STI were adjusted for sexual and other risk behavior correlates using multivariate regression techniques. Nine percent of AIs (n = 367) and 3.6% of whites (n = 7813) tested positive for an STI. Race differences were found for substance use (injection drug use, 3.1% AI vs. 1.3% white; alcohol use frequency, 2.01% AI vs. 2.5% white; binge drinking frequency, 1.25% AI vs. 1.53% white). Among sexually active respondents, AIs were more likely to have paid for sex (9%) than whites (3%). After adjustment, early sexual initiation (adjusted odds ratio, 1.69; 95% confidence interval, 1.19-2.41), no condom use at last sex (adjusted odds ratio, 1.47; 95% confidence interval, 1.08-2.01), and AI race (adjusted odds ratio, 2.45; 95% confidence interval 1.46-4.11) were significantly associated with having an STI. Individual-level sexual and other risk behaviors do not fully explain disparities in STIs among AIs compared with white young adults. Further examination of network and community factors is needed to explain these disparities.

Background and Objectives Many studies have shown a negative association between the consumption of soy products and the risk of some cancers, but little is known about the effect of soy consumption on nasopharyngeal carcinoma. We assessed the association between the consumption of soy products on nasopharyngeal carcinoma risk in Chinese individuals. Methods This case-control study included 600 (448 males and 152 females) incident cases of nasopharyngeal carcinoma, and an equal number of controls, matched according to gender, age (± 3 y) and household type to the nasopharyngeal carcinoma cases. All subjects were recruited from hospitals in Guangzhou, China. A face-to-face interview was conducted with each study individual to collect general information and habitual dietary intake using a 78-item quantitative food-frequency questionnaire. Odds ratios and their 95% confidence intervals were estimated using conditional logistic regression analyses. Results The median intakes of soy foods (in protein) were 0.5/0.5, 1.4/1.7, 2.7/3.3 and 6.1/7.7 (male/female) g/d in the quartiles 1 to 4. Both univariate and multivariate analyses showed no significant association between the consumption of soy proteins or soy isoflavones and the risk of nasopharyngeal carcinoma. The adjusted odds ratios (95% confidence intervals) between extreme quartiles were 0.97 (0.66-1.45) for soy proteins and 0.97 (0.66-1.42) for total isoflavones. Null associations were also observed between intake of the individual isoflavones daidzein, genistein and glycitein and NPC risk, with adjusted odds ratios for the extreme quartiles ranging between 0.73 and 1.23. Conclusion Habitual consumption of soy products had no significant effect on the risk of nasopharyngeal carcinoma in Chinese adults with a relatively low intake. PMID:24155974

Squamous cell carcinoma of the larynx and hypopharynx has the potential to invade the thyroid gland. Despite this risk, the proposition of either partial or total thyroidectomy as part of the surgical treatment of all such cases remains controversial. To evaluate the frequency of invasion of the thyroid gland in patients with advanced laryngeal or hypopharyngeal squamous cell carcinoma submitted to total laryngectomy or pharyngolaryngectomy and thyroidectomy; to determine whether clinic-pathological characteristics can predict glandular involvement. A retrospective case series with chart review, from January 1998 to July 2013, was undertaken in a tertiary care university medical center. An inception cohort of 83 patients with larynx/hypopharynx squamous cell carcinoma was considered. All patients had advanced stage disease (clinically T3-T4) and underwent total laryngectomy or total pharyngolaryngectomy in association with thyroidectomy. Adjuvant therapy was indicated when tumor or neck conditions required. Frequency of thyroid cartilage invasion was calculated; univariate and multivariate analysis of demographic, clinical and pathological characteristics associated with cartilage invasion were performed. The overall frequency of invasion of the thyroid gland was 18.1%. Glandular involvement was associated with invasion of the following structures: anterior commissure (odds ratio=5.13; 95% confidence interval 1.07-24.5), subglottis (odds ratio=12.44; 95% confidence interval 1.55-100.00) and cricoid cartilage (odds ratio=15.95; 95% confidence interval 4.23-60.11). Invasion of the thyroid gland is uncommon in the context of laryngopharyngeal squamous cell carcinoma. Clinical and pathological features such as invasion of the anterior commissure, subglottis and cricoid cartilage are more associated with glandular invasion.

Although relevant for health policy, so far only little is known about the extent to which persons avoid dental attendance because of associated costs. To examine the cost-relatedness of dental non-attendance in various older adulthood populations. Secondary analyses were conducted of data from wave 1 of the Survey of Health, Ageing, and Retirement in Europe (SHARE), which includes unique information on recent dental non-attendance and care foregone due to costs by persons aged 50+ from eleven European countries and Israel. Multivariate logistic regression analysis was used to detect differences in the extent to which dental non-attendance is attributable to associated costs. The study sample comprised 13 935 persons who did not access dental care within the past year. Levels of cost-related non-attendance differed between the twelve examined countries, ranging from 6.8% in Israel to 0.5% in Austria. Cost-related non-attendance was 47% less likely among persons with good as compared to compromised chewing ability (Odds Ratio: 0.53; 95% CI: 0.43-0.66). Cost-related non-attendance was 33% less likely among persons with tertiary as compared to (pre-) primary educational attainment (Odds Ratio: 0.67; 95% CI: 0.47-0.96). Cost-related dental non-attendance was significantly more likely among persons with low levels of general health (Odds Ratio for lowest vs. highest level of general health: 3.05; 95% CI: 1.88-4.95). The findings of the present study suggest that a relatively small proportion of dental non-attendance in older adulthood is cost-related. For specific population subgroups in various countries, however, dental care costs may still pose a relevant barrier to dental care. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

Background: Acromegaly and endocrine tumors are uncommon morbidities that are currently treated with different drugs. Objective: To determine the prescription patterns of somatostatin analogues in patients affiliated with the Health System of Colombia. Methods: Retrospective cohort study of patients of any age and sex treated with octreotide or lanreotide between January 2011 and August 2015. Socio-demographic, clinical (indications) and pharmacological (comedications) variables were considered. Multivariate analysis was performed with SPSS 23.0. Results: We identified 289 patients, with a mean age of 56.6 ± 14.0 years and female predominance (59.5%), who underwent treatment during the 56 months of monitoring. Octreotide was used in 56.1% of cases, followed by lanreotide (43.9%), both at approved doses. We found that 4.5% of subjects changed from one drug to another over the course of therapy, which was associated with being diabetic and receiving insulin (odds ratio: 4.27; 95% confidence interval: 1.23–14.84; p = 0.014). The most common indications were acromegaly (52.2% of cases) followed by neuroendocrine tumors (15.9%). The most common comorbidities were hypertension (39.4% of cases), depression (27.3%), dyslipidemia (23.3%), diabetes mellitus (23.5%) and hypothyroidism (23.5%). Being male (odds ratio: 0.57; 95% confidence interval: 0.35–0.94; p = 0.029) and belonging to the age group between 45 and 65 years (odds ratio: 0.44; 95% confidence interval: 0.21–0.90; p = 0.024) were significantly associated with a lower risk of receiving comedications. Conclusion: Somatostatin analogues are being used at recommended doses, especially in patients with acromegaly and neuroendocrine tumors. Variables associated with change in therapy were identified.

To identify the prevalence of smoking and the presence of variables associated with the habit in children and adolescents of both sexes, aged 7 to 17 years, resident in the city of Maceió. A cross-sectional epidemiological study of the student population of the both private and public education systems at elementary and high school level. Sample size was calculated based on the minimum predicted prevalence of a large number of variables, including smoking itself. Cluster sampling was employed. A questionnaire on smoking habits was completed during individual interviews with each student. Children who admitted having smoked on 1 or more day during the previous 30 were defined as current smokers. The variables analyzed were related to: the students (age, sex, previous experimentation with cigarettes and paid employment), their educational status (public/private school, daytime/evening lessons, grade and repeated years) and their families (economic status, smoking parents and separated parents). A total of 1,253 students were analyzed (547 were male, mean age was 12.4+/-2.9 years). Observed smoking prevalence was 2.4%. Multivariate statistical analysis demonstrated significant associations between smoking and: increased age (odds ratio: 1.31); previous experimentation with cigarettes (odds ratio: 33.96); studying during the evening (odds ratio: 5.43). It was observed that 286 students (22.8%) admitted having experimented with cigarettes (9% from 7 to 9 years; 21% from 10 to 14 years; 36% from 15 to 17 years). The prevalence of smoking among children and adolescents in the Maceió educational system is 2.4%, being most common among students aged 15 to 17 years, studying in the evening. Students who had experimented with cigarettes exhibited a 34 times greater chance of becoming smokers.

Significant early hematoma growth in patients with intracerebral hemorrhage is an independent predictor of poor functional outcome. Recently, the novel blend sign (BS) has been introduced as a new imaging sign for predicting hematoma growth in noncontrast computed tomography. Another parameter predicting increasing hematoma size is the well-established spot sign (SS) visible in computed tomographic angiography. We, therefore, aimed to clarify the association between established SS and novel BS and their values predicting a secondary neurological deterioration. Retrospective study inclusion criteria were (1) spontaneous intracerebral hemorrhage confirmed on noncontrast computed tomography and (2) noncontrast computed tomography and computed tomographic angiography performed on admission within 6 hours after onset of symptoms. We defined a binary outcome (secondary neurological deterioration versus no secondary deterioration). As secondary neurological deterioration, we defined (1) early hemicraniectomy under standardized criteria or (2) secondary decrease of Glasgow Coma Scale of >3 points, both within the first 48 hours after symptom onset. Of 182 patients with spontaneous intracerebral hemorrhage, 37 (20.3%) presented with BS and 39 (21.4%) with SS. Of the 81 patients with secondary deterioration, 31 (38.3%) had BS and SS on admission. Multivariable logistic regression analysis identified hematoma volume (odds ratio, 1.07 per mL; P≤0.001), intraventricular hemorrhage (odds ratio, 3.08; P=0.008), and the presence of BS (odds ratio, 11.47; P≤0.001) as independent predictors of neurological deterioration. The BS, which is obtainable in noncontrast computed tomography, shows a high correlation with the computed tomographic angiography SS and is a reliable predictor of secondary neurological deterioration after spontaneous intracerebral hemorrhage. © 2016 American Heart Association, Inc.

To assess the incidence of and risk factors for pressure ulcers among patients with advanced human immunodeficiency virus type 1 (HIV-1) infection. Multicenter trial that included 1258 consecutive patients infected with HIV-1 who had 1815 admissions to 16 acute care infectious disease units in Italy. Data were collected for demographic, clinical, immunologic, and virologic parameters. The chi-square test was used to compare categorical variables, and the Student t test was used for continuous variables. Univariate analysis was performed to examine possible risk factors for pressure ulcers by computing odds ratios; a multiple logistic regression model was used to obtain adjusted estimates of odds ratios while accounting for all possible risk factors. The incidence of pressure ulcers was 2.31 per 100 admissions, 3.33 per 100 patients, and 1.06 per 1000 patient days. All stages of pressure ulcers were represented in the sample: 7 Stage I (15.9%), 24 Stage II (54.5%), 8 Stage III (18.2%), and 5 Stage IV (11.4%). Multivariate analyses showed that being female, length of hospitalization, and clinical markers of HIV infection were independently associated with pressure ulcers. Mortality rates were 50% among patients with pressure ulcers and 7.2% among patients without pressure ulcers (P <.0001), with an attributable mortality rate of 42.8% and an odds ratio of 12.96 (95% confidence interval 6.99-24.22). A higher incidence of pressure ulcers was found in patients infected with HIV-1 when compared with noninfected patients. Because a longer hospitalization may increase the risk of developing a pressure ulcer, practitioners should be aware of the clinical conditions that may prolong a patient's hospital stay. Aggressive preventive strategies should be implemented to decrease the complications associated with pressure ulcers among patients infected with HIV-1.

Targeted efforts are needed to increase the number of medical students choosing psychiatry, but little is known about when students decide on their specialty or what factors influence their choice. The authors examined the timing and stability of student career choice of psychiatry compared with other specialties and determined what pre- and intra-medical school factors were associated with choosing a career in psychiatry. Using survey data from students who graduated from U.S. allopathic medical schools in 2013 and 2014 (N=29,713), the authors computed rates of psychiatry specialty choice at the beginning and end of medical school and assessed the stability of that choice. A multivariate-adjusted logistic regression and recursive partitioning were used to determine the association of 29 factors with psychiatry specialty choice. Choice of psychiatry increased from 1.6% at the start of medical school to 4.1% at graduation. The stability of psychiatry specialty choice from matriculation to graduation, at just over 50%, was greater than for any other specialty. However, almost 80% of future psychiatrists did not indicate an inclination toward the specialty at matriculation. A rating of "excellent" for the psychiatry clerkship (odds ratio=2.66), a major in psychology in college (odds ratio=2.58), and valuing work-life balance (odds ratio=2.25) were the factors most strongly associated with psychiatry career choice. Students who enter medical school planning to become psychiatrists are likely to do so, but the vast majority of students who choose psychiatry do so during medical school. Increasing the percentage of medical students with undergraduate psychology majors and providing an exemplary psychiatry clerkship are modifiable factors that may increase the rate of psychiatry specialty choice.

Endovascular therapy is increasingly used in acute ischemic stroke treatment and is now considered the gold standard approach for selected patient populations. Prior studies have demonstrated that eventual patient outcomes depend on both patient-specific factors and procedural considerations. However, these factors remain unclear for acute basilar artery occlusion stroke. We sought to determine prognostic factors of good outcome in acute posterior circulation large vessel occlusion strokes treated with endovascular therapy. We reviewed our prospectively collected endovascular databases at 2 US tertiary care academic institutions for patients with acute posterior circulation strokes from September 2005 to September 2015 who had 3-month modified Rankin Scale documented. Baseline characteristics, procedural data, and outcomes were evaluated. A good outcome was defined as a 90-day modified Rankin Scale score of 0 to 2. The association between clinical and procedural parameters and functional outcome was assessed. A total of 214 patients qualified for the study. Smoking status, creatinine levels, baseline National Institutes of Health Stroke Scale score, anesthesia modality (conscious sedation versus general anesthesia), procedural length, and reperfusion status were significantly associated with good outcomes in the univariate analysis. Multivariate logistic regression indicated that only smoking (odds ratio=2.61; 95% confidence interval, 1.23-5.56; P =0.013), low baseline National Institutes of Health Stroke Scale score (odds ratio=1.09; 95% confidence interval, 1.04-1.13; P <0.0001), and successful reperfusion status (odds ratio=10.80; 95% confidence interval, 1.36-85.96; P =0.025) were associated with good outcome. In our retrospective case series, only smoking, low baseline National Institutes of Health Stroke Scale score, and successful reperfusion status were associated with good outcome in patients with posterior circulation stroke treated with endovascular therapy. © 2017 American Heart Association, Inc.

Postoperative nausea and vomiting (PONV) is one of the most common and distressing complications after general anesthesia and surgery, with young non-smoking females receiving postoperative opioids being high-risk patients. This register-based study aims to evaluate the effect of low-dose haloperidol (0.5 mg intravenously) directly after induction of general anesthesia to reduce the incidence of PONV in the postoperative anesthesiological care unit (PACU). Multivariable regression models were used to investigate the association between low-dose haloperidol and the occurrence of PONV using a patient registry containing 2,617 surgical procedures carried out at an university hospital. Haloperidol 0.5 mg is associated with a reduced risk of PONV in the total collective (adjusted odds ratio = 0.75, 95% confidence interval: [0.56, 0.99], p = 0.05). The results indicate that there is a reduced risk in male patients (adjusted odds ratio = 0.45, 95% confidence interval: [0.28, 0.73], p = 0.001) if a dose of 0.5 mg haloperidol was administered while there seems to be no effect in females (adjusted odds ratio = 1.02, 95% confidence interval: [0.71, 1.46], p = 0.93). Currently known risk factors for PONV such as female gender, duration of anesthesia and the use of opioids were confirmed in our analysis. This study suggests that low-dose haloperidol has an antiemetic effect in male patients but has no effect in female patients. A confirmation of the gender-specific effects we have observed in this register-based cohort study might have major implications on clinical daily routine.
