We performed genome wide association (GWA) analyses for mean food intake and environmental variance of food intake (using the coefficient of environmental variation, CVE, as the metric for environmental variance) and identified molecular polymorphisms associated with both traits. Validation experiments using RNAi-knockdown confirmed 24 of 31 (77%) candidate genes affecting food intake and/or variance of food intake, and a test cross between selected DGRP lines confirmed a SNP affecting mean food intake identified in the GWA analysis. The majority of the validated candidate genes were novel with respect to feeding behavior, and many had mammalian orthologs implicated in metabolic diseases.Functional magnetic resonance imaging (fMRI) and particularly resting state fMRI (rs-fMRI) is widely used to investigate resting state brain networks (RSNs) on the systems level. Echo planar imaging (EPI) is the state-of-the-art imaging technique for most fMRI studies. Therefore, improvements of EPI might lead to increased sensitivity for a large amount of studies performed every day. A number of developments to shorten acquisition time have been recently proposed and the multiband technique, allowing the simultaneous acquisition of multiple slices yielding an equivalent reduction of measurement time, is the most promising among them. While the prospect to significantly reduce acquisition time by means of high multiband acceleration factors (M) appears tempting, signal quality parameters and the sensitivity to detect common RSNs with increasing M-factor have only been partially investigated up to now. In this study, we therefore acquired rs-fMRI data from 20 healthy volunteers to systematically investigate signal characteristics and sensitivity for brain network activity in datasets with increasing M-factor, M = 2 - 4. Combined with an inplane, sensitivity encoding (SENSE), acceleration factor, S = 2, we applied a maximal acceleration factor of 8 (S2×M4). Our results suggest that an M-factor of 2 (total acceleration of 4) only causes negligible SNR decrease but reveals common RSN with increased sensitivity and stability. Further M-factor increase produced random artifacts as revealed by signal quality measures that may affect interpretation of RSNs under common scanning conditions. Given appropriate hardware, a mb-EPI sequence with a total acceleration of 4 significantly reduces overall scanning time and clearly increases sensitivity to detect common RSNs. Together, our results suggest mb-EPI at moderate acceleration factors as a novel standard for fMRI that might increase our understanding of network dynamics in healthy and diseased brains.The expression pattern of Sohlh1 (spermatogenesis and oogenesis specific basic helix-loop-helix 1) and Sohlh2 in mice has been reported in previous studies. Sohlh1 and Sohlh2 are specifically expressed in spermatogonia, prespermatogonia in male mice and oocytes of primordial and primary follicles in female mice. In this report, we studied the expression pattern of Sohlh1 and Sohlh2 in human adult tissues. Immunohistochemical staining of Sohlh1 and Sohlh2 was performed in 5 samples of normal ovaries and testes, respectively. The results revealed that Sohlh genes are not only expressed in oocytes and spermatogonia, but also in granular cells, theca cells, Sertoli cells and Leydig cells, and in smooth muscles of blood vessel walls. To further investigate the expression of Sohlh genes in other adult human tissues, we collected representative normal adult tissues developed from three embryonic germ layers. Compared with the expression in mice, Sohlhs exhibited a much more extensive expression pattern in human tissues. Sohlhs were detected in testis, ovary and epithelia developed from embryonic endoderm, ectoderm and tissues developed from embryonic mesoderm. Sohlh signals were found in spermatogonia, Sertoli cells and also Leydig cells in testis, while in ovary, the expression was mainly in oocytes of primordial and primary follicles, granular cells and theca cells of secondary follicles. Compared with Sohlh2, the expression of Sohlh1 was stronger and more extensive. Our study explored the expression of Sohlh genes in human tissues and might provide insights for functional studies of Sohlh genes.Acute arterial occlusion is an emergency condition that, if untreated, can lead to serious complications and potential limb amputation. Risk factors for acute arterial occlusion include aortic atherosclerosis, arterial trauma, recent myocardial infarction, and atrial fibrillation. We present a patient with no history of peripheral vascular disease who presented to the emergency department with severe bilateral leg pain. Computed tomography angiography was performed showing bilateral acute arterial occlusions. Emergent vascular surgery was performed to remove the thrombus and establish perfusion in order to prevent bilateral lower leg amputation.

To assess the impact of a pre-hospital critical care team (CCT) on survival from out-of-hospital cardiac arrest (OHCA).

We undertook a retrospective observational study, comparing OHCA patients attended by advanced life support (ALS) paramedics with OHCA patients attended by ALS paramedics and a CCT between April 2011 and April 2013 in a single ambulance service in Southwest England. We used multiple logistic regression to control for an anticipated imbalance of prognostic factors between the groups. The primary outcome was survival to hospital discharge. All data were collected independently of the research.

1851 cases of OHCA were included in the analysis, of which 1686 received ALS paramedic treatment and 165 were attended by both ALS paramedics and a CCT. Unadjusted rates of survival to hospital discharge were significantly higher in the CCT group, compared to the ALS paramedic group (15.8% and 6.5%, respectively, p<0.001). After adjustment using multiple logistic regression, the effect of CCT treatment was no longer statistically significant (OR 1.54, 95% CI 0.89-2.67, p=0.13). Subgroup analysis of OHCA with first monitored rhythm of ventricular fibrillation or pulseless ventricular tachycardia showed similar results.

Pre-hospital critical care for OHCA was not associated with significantly improved rates of survival to hospital discharge. These results are in keeping with previously published studies. Further research with a larger sample size is required to determine whether CCTs can improve outcome in OHCA.

Voltage-gated potassium channel-complex antibodies (VGKC-cAbs) encephalitis, a treatable autoantibody encephalopathy, has been previously reported to clinically mimic sporadic Creutzfeldt-Jakob disease. Among available clinical clues to distinguish them, periodic sharp wave complexes, a typical finding in sporadic Creutzfeldt-Jakob disease, have never been reported in association with VGKC-cAbs encephalitis.

A 76-year-old man was transferred to a tertiary neurology center with a clinical history of 6-month weight loss, cognitive disturbance, and nonspecific generalized weakness. He had two seizures the month before transfer and then evolved to severe encephalopathy, requiring mechanical ventilation. Periodic sharp wave complexes every 1 to 2 seconds over slowed background were found on EEG, and MRI showed cerebellar and bifrontal cortical T2/FLAIR/DWI hypersignal without restricted diffusion on ADC mapping. Pancorporal positron emission tomography scan was negative. An immunotherapy trial did not improve entities appropriately, when present. These clues are of paramount importance because VGKC-cAbs encephalitis is a treatable disease.For research and policy issues, it is very important to measure the evolution of socioeconomic differences in the adolescent fertility rate over time (AFER) in order to be able to provide a quantitative description of such an evolution. By combining well reputed Chilean data, this study computes a ratio of AFER (15-17 years-old) between the 30% of the population living in economically worst off areas (the numerator) against the corresponding 30% better off segment of the population (the denominator). This ratio of AFER by relative socioeconomic status shows a stable evolution from 1.45 in the year 1990 to 1.10 in 2011. Sexual initiation, whose association with AFER is well established, also shows a dropping ratio, from 1.24 in 1997 to 1.01 in 2012. The size of some dimensions of socioeconomic inequalities in adolescent fertility and sexual initiation has being decreasing between 1990 and 2011. This exercise shows that even in Chile, the most unequal country among the Organisation for Economic Co-operation and Development, there are some improvements in health inequality.Factors associated with paid work were examined in a probabilistic sample of 3,320 adults (50-69 years) in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. Prevalence of paid work was 62.8% in men and 35.8% in women. For both men and women, paid work was positively associated with schooling and negatively associated with self-rated health. The probability of having paid work was higher for single women and those who knew someone that had suffered discrimination at the workplace. For men, prevalence of paid work varied from 67.2% in those with ≥ 8 years of schooling and better self-rated health, as compared to 37.8% in those with less schooling and poor self-rated health (PR = 0.56; 95%CI 0.37-0.87). In women, the corresponding prevalence rates were 42.1% and 3.6% (PR = 0.09; 95%CI 0.03-0.26). For women with little schooling and poor self-rated health, the likelihood of having paid work was ten times lower than for their male counterparts.This study aimed to determine the validity of self-rated measures as an indicator of dental treatment needs in adults and the elderly. The sample consisted of individuals that participated in the National Oral Health Survey and the Survey on Oral Health Conditions in Minas Gerais State. Self-rated needs for dental treatment and total prostheses were compared to need based on dental examination, defined as the gold standard. The quality of measures was assessed by sensitivity, specificity, and predictive values. Sensitivity varied from 51% to 90%, and specificity from 56% to 90%. Selleckchem UNC3866 Positive predictive values were 11% to 95% and negative predictive values were 23% to 99%. Self-rated need for dental treatment in adults and for total prostheses in the elderly showed acceptable validity. Meanwhile, self-rated need for dental treatment in the elderly and for total prostheses in adults were not considered useful, due to their low performance.The aim of this study was to perform a budget impact analysis on the adoption of percutaneous occlusion of ostium secundum atrial septal defects in the Brazilian Unified National Health System. Costs were collected using micro-costing technique from medical records for each treatment technique (conventional surgery versus percutaneous septal occluder) at a public federal hospital specialized in high-complexity cardiology. The analysis showed that expenditures associated with percutaneous occlusion were lower than with conventional surgery, and sensitivity analysis confirmed the cost reduction in several scenarios, showing a significant budget impact with a 30% adoption rate for the percutaneous occluder (savings of approximately 1.5 million dollars per year). The study indicates that the adoption of the percutaneous septal occluder would mean cost savings of approximately 3.5 million dollars for the Brazilian public health system.
