Serum metabolomic profiling of incident type 2 diabetes mellitus in the Multi-Ethnic Study of Atherosclerosis and Rotterdam Study.

Objective: This study aimed to investigate serum metabolomic biomarkers associated with incident type 2 diabetes mellitus (T2DM) and evaluate their performance in improving T2DM risk prediction.

Methods: Untargeted proton nuclear magnetic resonance (1H NMR) spectroscopy-based metabolomics analyses were conducted in the Multi-Ethnic Study of Atherosclerosis (MESA; n=3460; discovery cohort) and Rotterdam Study (RS; n=1556; replication cohort). Multivariable cause-specific hazards models were used to analyze the associations between 23,571 serum metabolomic spectral variables and incident T2DM.

Steroid Hormone Biosynthesis and Dietary Related Metabolites Associated with Excessive Daytime Sleepiness.

Background: Excessive daytime sleepiness (EDS) is a complex sleep problem that affects approximately 33% of the United States population. Although EDS usually occurs in conjunction with insufficient sleep, and other sleep and circadian disorders, recent studies have shown unique genetic markers and metabolic pathways underlying EDS. Here, we aimed to further elucidate the biological profile of EDS using large scale single- and pathway-level metabolomics analyses.

Nephrologists' perspectives on communication and decision-making regarding technique survival in peritoneal dialysis: an international qualitative interview study.

Objectives: Peritoneal dialysis (PD) allows patients increased autonomy and flexibility; however, both infectious and non-infectious complications may lead to technique failure, which shortens treatment longevity. Maintaining patients on PD remains a major challenge for nephrologists. This study aims to describe nephrologists' perspectives on technique survival in PD.

Potential Long-Term Health Problems Associated with Ultra-Endurance Running: A Narrative Review.

It is well established that physical activity reduces all-cause mortality and can prolong life. Ultra-endurance running (UER) is an extreme sport that is becoming increasingly popular, and comprises running races above marathon distance, exceeding 6 h, and/or running fixed distances on multiple days. Serious acute adverse events are rare, but there is mounting evidence that UER may lead to long-term health problems.

Sports safety matting diminishes cardiopulmonary resuscitation quality and increases rescuer perceived exertion.

Objectives: Compliant surfaces beneath a casualty diminish the quality of cardiopulmonary resuscitation (CPR) in clinical environments. To examine this issue in a sporting environment, we assessed chest compression quality and rescuer exertion upon compliant sports safety matting.

Methods: Twenty-seven advanced life support providers volunteered (13 male/14 female; mass = 79.

Does muscle improve validated outcome measures in open tibial fractures? New insights from a cohort study of the anterolateral thigh flap (ALT) versus ALT-Vastus lateralis flaps.

The benefits of the muscle in open lower limb fractures remain to be determined. This study compared statistically equivalent groups of open tibial fractures treated by free anterolateral thigh (ALT) flaps or ALT flaps incorporating muscle (ALT-Vastus lateralis/ALT- VL). Method and Results: Chang Gung Memorial Hospital, Taiwan, 2004-2008, 49 free flaps in open lower limb fractures (38 open tibial) were specifically reconstructed with free ALT or ALT-VL flaps.

Cardiorespiratory demands of competitive rock climbing.

Rock climbing has become a mainstream sport, contested on the Olympic stage. The work/rest pattern of bouldering is unique among disciplines, and little is known about its physiological demands. This study characterised the cardiorespiratory responses to simulated competition.

Age and gender considerations on the symptomology in patients with superior semicircular canal dehiscence: A systematic review and case illustration.

Superior semicircular canal dehiscence (SSCD) is caused by a fistula in the arcuate eminence, creating vestibular and auditory disturbances. We aim to determine the effects of gender and age on symptom prevalence and resolution in patients with SSCD. A Boolean search was conducted through four separate scientific databases.

Outcomes of ST Elevation Myocardial Infarction Complicated by Out-of-Hospital Cardiac Arrest (from the Los Angeles County Regional System).

The objective of this study was to evaluate the time to primary percutaneous coronary intervention (PCI) and the outcome for patients with ST elevation myocardial infarction (STEMI) complicated by out-of-hospital cardiac arrest (OHCA). In this regional system, all patients with STEMI and/or OHCA with return of spontaneous circulation were transported to STEMI Receiving Centers. The outcomes registry was queried for patients with STEMI with underwent primary PCI from April 2011 to December 2014.

Changes in functional magnetic resonance imaging with meditation: A pilot study.

Background: The neural substrates of meditation are not well understood. Meditation is theorized to be a conscious mental process that induces a set of complex physiological changes within the areas of the brain termed as the "relaxation response."

Aims And Objective: Pilot data of a functional magnetic resonance imaging (fMRI) study is presented to observe and understand the selective activations of designated brain regions during meditation.

Each-step activation of oxidative phosphorylation is necessary to explain muscle metabolic kinetic responses to exercise and recovery in humans.

Key Points: The basic control mechanisms of oxidative phosphorylation (OXPHOS) and glycolysis during work transitions in human skeletal muscle are still a matter of debate. We used simulations of skeletal muscle bioenergetics to identify key system features that contribute to this debate, by comparing kinetic model outputs with experimental human data, including phosphocreatine, pH, pulmonary oxygen uptake and fluxes of ATP production by OXPHOS (vOX), anaerobic glycolysis and creatine kinase in moderate and severe intensity exercise transitions. We found that each-step activation of particular OXPHOS complexes, NADH supply and glycolysis, and strong (third-order) glycolytic inhibition by protons was required to reproduce observed phosphocreatine, pH and vOX kinetics during exercise.

Rare Manifestation of a c.290 C>T, p.Gly97Glu VCP Mutation.

Introduction. The valosin-containing protein (VCP) regulates several distinct cellular processes. Consistent with this, VCP mutations manifest variable clinical phenotypes among and within families and are a diagnostic challenge.

Targeted sequencing and identification of genetic variants in sporadic inclusion body myositis.

Sporadic inclusion body myositis (sIBM) has clinical, pathologic and pathomechanistic overlap with some inherited muscle and neurodegenerative disorders. In this study, DNA from 79 patients with sIBM was collected and the sequencing of 38 genes associated with hereditary inclusion body myopathy (IBM), myofibrillar myopathy, Emery-Dreifuss muscular dystrophy, distal myopathy, amyotrophic lateral sclerosis and dementia along with C9orf72 hexanucleotide repeat analysis was performed. No C9orf72 repeat expansions were identified, but; 27 rare (minor allele frequency <1%) missense coding variants in several other genes were identified.

A novel mutation in VCP causes Charcot-Marie-Tooth Type 2 disease.

Mutations in VCP have been reported to account for a spectrum of phenotypes that include inclusion body myopathy with Paget's disease of the bone and frontotemporal dementia, hereditary spastic paraplegia, and 1-2% of familial amyotrophic lateral sclerosis. We identified a novel VCP mutation (p.Glu185Lys) segregating in an autosomal dominant Charcot-Marie-Tooth disease type 2 family.

Use of prostatic massage in combination with antibiotics in the treatment of chronic prostatitis.

Chronic prostatitis is often refractory to antibiotics, however biopsy and molecular data indicate persistent symptoms may be due to occult infection. Combining antibiotic therapy with regular prostatic massage has been suggested as an effective therapy for some of these men. From November 1996 to December 1998, 73 men with chronic pelvic pain syndromes were treated with antibiotics and prostatic massage.

Variants of N-acetyltransferase NAT1 and a case-control study of colorectal adenomas.

N-acetyltransferase NAT1, together with enzymes CYP1A2 and NAT2, helps convert heterocyclic amines to mutagens. Epidemiologic studies of the association of variants of these enzymes with colorectal cancer may provide indirect support for a heterocyclic amine mechanism. We used single strand conformation polymorphism and heteroduplex analysis to screen fro mutations in the NAT1 coding region in a case-control study (n = 932) of colorectal adenomas, which are precursors to cancer.
