In Germany, medical students in their final year will work in hospitals or medical offices to gain clinical experience. The final year is designed to prepare medical students for their work as junior doctors. It is divided into three parts and includes internal medicine and general surgery as mandatory parts. Many students develop enthusiasm or lack of enthusiasm while working in specific disciplines and often apply for jobs based on their experience in their final year. Despite the importance of this educational phase, the 36 medical faculties have implemented several different curricula and there is significant heterogeneity...

The majority of World Health Organization grade II and grade III gliomas harbor heterozygous mutations in the metabolic enzyme isocitrate dehydrogenase 1 (IDH1), and tumors with an IDH wild-type status show molecular features of a glioblastoma and simply may constitute a separate disease entity. This discovery has led to a profound shift in the way that gliomas are classified and, consequently, how treatment decisions are made. We will review the current understanding of IDH- mutant gliomagenesis and the preclinical models being used to investigate the underlying biology of these tumors and to explore new therapeutic options for these patients...

Estimating the malignancy level of tumors is key to management, and has been part of oncology practice for the past ∼100 years. A central aspect of assessing malignancy level is based on histological "grading"-a process in which a pathologist evaluates microscopic features of a tumor and interprets those findings in light of large prognostic studies. For the diffuse astrocytic gliomas, there have been many such studies over the past century and these have proven useful in estimating prognosis for patients...

Introduction: We aimed to determine the prospective association of smoking status, smoking intensity, and smoking cessation with the risk of hearing loss in a large Japanese cohort. Methods: The cohort study included 50195 employees, who were aged 20-64 years and free of hearing loss at baseline. Participants were followed up for a maximum of 8 years. Pure-tone audiometric testing was performed annually to identify hearing loss at 1 and 4 kHz. Cox proportional hazards regression models were used to investigate the association between smoking and hearing loss...

Introduction: The current evolution of surgical practices is increasingly trending toward hyper-specialization. For military surgeons, their practice in France does not differ from their civilian counterparts. In contrast, in external operations, they have to deal with specific war injuries in austere conditions. They are also required to take care of local populations. Therefore, specific training is necessary, and the French Military Health Service Academy (Ecole du Val-de-Grâce) Paris has set up a specific training called Advanced Course for Deployment Surgery (ACDS) in 2007...

Background: Much research has focused on stress related to deployments; however, a substantial proportion of soldiers never deploy. In a study of 1.3 million veterans, suicide risk was higher among veterans who had never deployed. Thus, not being deployed may have an impact on soldiers' well-being; however, no measures exist to assess emotions regarding non-deployment. We aimed to develop and test an original measure of non-deployment emotions. Methods: We examined the Non-Deployment Emotions (NDE) questionnaire, a novel four-item measure of guilt, unit value, unit camaraderie, and unit connectedness in a sample of never-deployed male and female US Army Reserve/National Guard (USAR/NG) soldiers (N = 174)...

Quality problem: For smokers, hospital admission is accompanied by forced involuntary nicotine abstinence due to smoke-free site/grounds policies. An audit of patients admitted to our surgical wards revealed that identification of smoking status was inadequate and that nicotine addiction management (NAM) was infrequently offered. The project aimed to enhance both these metrics by initiating NAM in the post anesthesia care unit (PACU). Initial assessment: Out of 744 patients admitted to our PACU in August 2015, 54% had their smoking status documented...

Objective: Available studies on implementation of evidence-based psychotherapy (EBP) for patients attending Department of Veterans Affairs (VA) residential post-traumatic stress disorder (PTSD) programs rely on therapist self-report of EBP delivery. Patient-level data on receipt of EBP are needed both to corroborate therapist self-report and to understand patient factors that predict receipt of EBPs for PTSD. Materials and Methods: We identified 159 therapists from 38 VA residential PTSD programs who responded to a survey about EBP implementation during the 2015 fiscal year (FY15)...

Sandy beaches are unique ecosystems increasingly exposed to human-induced pressures. Consistent with emerging frameworks promoting this holistic approach towards beach management, is the need to improve the integration of social data into management practices. This paper aims to increase understanding of links between demographics and community values and preferred beach activities, as key components of the social dimension of the beach environment. A mixed method approach was adopted to elucidate users' opinions on beach preferences and community values through a survey carried out in Manly Local Government Area in Sydney Harbour, Australia...

PURPOSE: Activation of CB1 receptors, produces anticonvulsant effect accompanied by memory disturbance both in animal seizure tests and in patients with epilepsy. Few reports considered the role of CB2 receptor on seizure susceptibility and cognitive functions. The aim of the present study was to explore the effect of a selective CB2 receptor agonist β-caryophyllene (BCP) in models of seizures and cognition in mice. METHODS: Dose-dependent effects of BCP was studied in maximal electroshock seizure (MES) test, subcutaneous pentylenetetrazole (scPTZ) test and Morris water maze test...

Vaginal birth after caesarean (VBAC) delivery remains a controversial topic, and one for which there is a lack of robust data to guide clinicians and parturients regarding their best option for mode of delivery in a subsequent pregnancy. In many developed countries the trend observed in recent years is that of progressively reduced VBAC rates, and hence increased use of elective repeat caesarean section (ERCS). This factor has contributed, more than any other, to the disproportionately high caesarean section (CS) rates in many countries...

Substance-related and behavioral addictions are extremely prevalent and represent a major public health concern. In the ongoing attempt to understand the addictive personality, contradictory results have arisen from studies that have explored personality traits in different addiction populations. The diversity across addiction types suggests that some of these inconsistencies stem from distinct personalities underlying each addiction. The present study compares the personality profiles of several addictions, representing both substance (drugs and alcohol) and behavioral (gambling and sex) subtypes...

Cancer occurrence can be understood as the result of dysfunctions in immune tumoral microenvironment. Here we review the recent understandings of those microenvironment changes, regarding their causes and prognostic significance in head and neck (HN) carcinoma. We will focus on HN squamous cell cancer (SCC) and nasopharyngeal carcinomas (NPC). Their overall poor prognosis may be improved with immunotherapy in a subset of patients, as supported by current clinical trials. However, finding reliable markers of therapeutic response is crucial for patient selection, due to potential severe adverse reactions and high costs...

ADHD is associated with automobile crashes, traffic fatalities, and serious road trauma, but it is unclear whether this risk is (a) driven by ADHD symptoms specifically, and (b) unique to ADHD or transdiagnostic across psychiatric disabilities, such as depression, that also have concentration problems as core symptoms. The current study provides the first prospective, continuously-monitored evaluation of crash risk related to ADHD symptoms, including the first on-road comparison of ADHD with another high-prevalence psychiatric disability (depression)...

Human papillomavirus (HPV) is a common viral infection worldwide associated with a variety of cancers. The integration of the HPV genome in these patients causes chromosomal instability and triggers carcinogenesis. The aim of this study was to investigate the HPV-16 genome physical status in four major cancers related to HPV infection. Formalin-fixed paraffin-embedded blocks from our previous projects on head and neck, colorectal, penile, and cervical cancers were collected, and HPV-16-positive specimens were used for further analysis...

The onset of adolescence in humans is marked by hormonal changes that give rise to secondary sexual characteristics, noted as puberty. It has, however, proven challenging to unravel to what extent pubertal changes may have organizing effects on the brain beyond chronological age, as reported in animal studies. The present longitudinal study aimed to characterize the unique effects of age and puberty on subcortical brain volumes and included three waves of data collection at two-year intervals and 680 T1-weighted MRI scans of 271 participants (54% females) aged between 8 and 29 years old...

BACKGROUND AND AIMS: It is uncertain whether resolution of fatty liver can improve cardiovascular disease risk factors, independently of changes in body mass index (BMI). Our aim was to test whether resolution of fatty liver is associated with improvements in components of the lipid profile, independently of changes in BMI, and to quantify and compare the magnitude of benefit of resolution of liver fat, and decreases in BMI on the lipid profile. METHODS: 36,195 subjects with fatty liver were studied...
