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 meningiomas, the most common primary brain tumor, are considered to be benign, and characteristic magnetic resonance imaging features allow a preliminary diagnosis. Meningiomas can be classified in the World Health Organization system as grade I, II, or III, depending on various histological features. In many cases, observation is the preferred management option, although this means the absence of a histological diagnosis. If necessary, standard therapy consists of surgery with or without adjuvant radiation, depending on the tumor grade and the degree of resection...

Malignant glioma is a common type of brain tumor that remains largely incurable. Although a definitive cell of origin of gliomas remains elusive, numerous population studies, sequencing efforts, and genetically engineered mouse models have contributed to our understanding of the early events that may lead to gliomagenesis. Herein we summarize our current knowledge on the population epidemiology of gliomas, heritable genetic risk factors, the somatic events that contribute to tumor evolution, and mouse models that have shed light on the glioma cell of origin...

Pseudomonas aeruginosa (P. aeruginosa) is a common contaminant associated with product recalls in the home and personal care (HPC) industry. Preservation systems are used to prevent spoilage and protect consumers, but greater knowledge is needed of preservative resistance mechanisms used by P. aeruginosa contaminants. We aimed to identify genetic pathways associated with preservative exposure by using an industrial P. aeruginosa strain and implementing RNA-Seq to understand gene expression changes in response to industry relevant conditions...

Objective: Problem list data is a driving force for many beneficial clinical tools, yet these data remain underutilized. We performed a systematic literature review, pulling insights from previous research, aggregating insights into themes, and distilling themes into actionable advice. We sought to learn what changes we could make to existing applications, to the clinical workflow, and to clinicians' perceptions that would improve problem list utilization and increase the prevalence of problems data in the electronic medical record...

Introduction: Military prehospital and en route care (ERC) directly impacts patient morbidity and mortality. Provider knowledge and skills are critical variables in the effectiveness of ERC. No Navy doctrine defines provider choice for patient transport or requires standardized provider training. Frequently, Search and Rescue Medical Technicians (SMTs) and Navy Nurses (ERC RNs) are tasked with this mission though physicians have also been used. Navy ERC provider training varies greatly by professional role...

Patient safety is an increasing concern for health systems internationally. The majority of administrative work in UK general practice takes place in the context of organisational routines such as repeat prescribing and test results handling, where high workloads and increased clinician dependency on administrative staff have been identified as an emerging safety issue. Despite this trend, most research to date has focused on the redistribution of the clinical workload between doctors, nurses and allied health professionals within individual care settings...

BACKGROUND: Nursing education contains both theoretical and practical training processes. Clinical training is the basis of nursing education. The quality of clinical training is closely related to the quality of the clinical learning environment. OBJECTIVES: This study aimed to determine the transfer of theoretical knowledge into clinical practice by nursing students and the difficulties they experience during this process. METHODS: A qualitative research design was used in the study...

BACKGROUND: Sustaining and strengthening nurses 'contributions to public and population health in the 21st century depends in part on nursing education. Clearly articulated entry-to-practice competencies will contribute to the capacity of undergraduate nursing education programs to prepare graduates to promote local, national and global population health. OBJECTIVES: The Canadian Association of Schools of Nursing created the Public Health Task Force to develop consensus on core, national entry-to-practice competencies in public health nursing for undergraduate nursing students and to support these competencies with corresponding online teaching strategies...

OBJECTIVES: High-fat high-sucrose diet (HFHS) overfeeding is one of the main factors responsible for the increased prevalence of metabolic disorders. Elevated levels of branched-chain amino acids (BCAAs) have been associated with metabolic dysfunctions, including insulin resistance (IR). The aim of this study was to elucidate whether elevated BCAA levels are the cause or the consequence of IR and to determine the mechanisms and tissues involved in such a phenotype. METHODS: We performed a 2-mo follow-up on minipigs overfed an HFHS diet and focused on kinetics fasting and postprandial (PP) BCAA levels and BCAA catabolism in key tissues...

Base excision repair (BER) is a major defense pathway against spontaneous DNA damage. This multistep process is initiated by DNA glycosylases that recognise and excise the damaged base, and proceeds by the concerted action of additional proteins that perform incision of the abasic site, gap filling and ligation. BER has been extensively studied in bacteria, yeasts and animals. Although knowledge of this pathway in land plants is increasing, there are no reports detecting BER in algae. We describe here an experimental in vitro system allowing the specific analysis of BER in the model alga Chlamydomonas reinhardtii...

Metabotropic glutamate (mGlu) receptors are expressed in key regions of the cortex and the thalamus and are known to regulate spike and wave discharges (SWDs), the electroclinical hallmarks of absence seizures. Recent preclinical studies have highlighted the therapeutic potential of selective group I and III mGlu receptor subtype allosteric modulators, which can suppress pathological SWDs. Of particular interest are positive allosteric modulators (PAMs) for mGlu5 receptors, as they currently show the most promise as novel anti-absence epilepsy drugs...

Animal and human research suggests that testosterone is associated with hippocampal structure and function. Studies examining the association between testosterone and either hippocampal structure or hippocampal-mediated cognitive processes have overwhelmingly focused on the effects of testosterone alone, without considering the interaction of other neuroendocrine factors. The aim of the present study was to examine the interactive effects of testosterone and cortisol in relation to hippocampal volume and episodic memory in a sample of late-middle aged men from the Vietnam Era Twin Study of Aging...

The enzyme indoleamine 2,3-dioxygenase 1 (IDO1) acts immunomodulatory and restricts bacterial growth. In the uterus of women and mice, it likely contributes to tissue homeostasis and disease pathogenesis. Pregnancy failure in mares is often caused by endometritis and endometrosis. The pathogenesis of nonsuppurative endometritis and endometrosis is still uncertain. To the authors' knowledge, no information on IDO1 expression in the equine endometrium is published. Aim of this study was to examine the presence of IDO1 as transcripts and proteins in the healthy and diseased endometrium of 25 mares and to determine its cellular expression...

Marine protected areas (MPAs) are designed to reduce threats to biodiversity and ecosystem functioning from anthropogenic activities. Assessment of MPAs effectiveness requires synchronous sampling of protected and non-protected areas at multiple spatial and temporal scales. We used an autonomous underwater vehicle to map benthic communities in replicate 'no-take' and 'general-use' (fishing allowed) zones within three MPAs along 7o of latitude. We recorded 92 taxa and 38 morpho-groups across three large MPAs...
