The impact of age and sex on body composition and glucose sensitivity in C57BL/6J mice.

A paucity of data exists regarding sex differences in age-related obesity and insulin resistance, particularly in the preclinical murine model. The purpose of this study was to determine the effects of age and sex on insulin action and body composition in C57BL/6J mice. Aged (AG, 18 months old) male C57BL/6J mice, glucose tolerance was diminished compared to young (YG, 6 months old) male mice (Area Under Curve: 95,103 ± 6818 vs.

Exposure of Candida albicans β (1,3)-glucan is promoted by activation of the Cek1 pathway.

Candida albicans is among the most common causes of human fungal infections and is an important source of mortality. C. albicans is able to diminish its detection by innate immune cells through masking of β (1,3)-glucan in the inner cell wall with an outer layer of heavily glycosylated mannoproteins (mannan).

Reconceptualizing the role of emergency care in the context of global healthcare delivery.

Since the adoption of the Sustainable Development Goals in 2015, innovation in global healthcare delivery has been recognized as a vital avenue for strengthening health systems and overcoming present implementation bottlenecks. In the recent rapid development of the science of global health-care delivery, emergency care-a critical element of the health system-has been widely overlooked. Emergency care plays a vital role in the health system through providing immediately responsive care and serving as one of the main entry points for those with symptomatic disease.

Monoclonal antibody targeting BDCA2 ameliorates skin lesions in systemic lupus erythematosus.

Background: Plasmacytoid DCs (pDC) produce large amounts of type I IFN (IFN-I), cytokines convincingly linked to systemic lupus erythematosus (SLE) pathogenesis. BIIB059 is a humanized mAb that binds blood DC antigen 2 (BDCA2), a pDC-specific receptor that inhibits the production of IFN-I and other inflammatory mediators when ligated. A first-in-human study was conducted to assess safety, tolerability, and pharmacokinetic (PK) and pharmacodynamic (PD) effects of single BIIB059 doses in healthy volunteers (HV) and patients with SLE with active cutaneous disease as well as proof of biological activity and preliminary clinical response in the SLE cohort.

A Descriptive and Geospatial Analysis of Environmental Factors Attributing to Sudden Unexpected Infant Death.

This study examined medicolegal death investigation records and autopsy reports of a medical examiner's office to identify the circumstances surrounding sudden unexpected infant deaths (SUID) and geospatial analyses to pinpoint areas of infant death concentration. Analysis of 732 records of SUID deaths occurring in a 10-year span resulted in the conclusion that environmental factors associated with the sudden death were to some extent modifiable. Co-sleeping (sharing a sleeping surface, or bed-sharing) on various surfaces (mattress, pallet, couch) occurred in 53.

Going with the Flo: The Role of Flo11-Dependent and Independent Interactions in Yeast Mat Formation.

Strains of the bakers' yeast that are able to generate a multicellular structure called a mat on low percentage (0.3%) agar plates are given a selective advantage over strains that cannot exhibit this phenotype. This environment may exhibit some similarities to the rotting fruit on which often grows in nature.

Health care facilities and personnel are critical to disaster response. We assessed the current state of disaster preparedness and response capacity among Tanzanian regional hospitals.

Relating Seasonal Hunger and Prevention and Coping Strategies: A Panel Analysis of Malawian Farm Households.

Relative to chronic hunger, seasonal hunger in rural and urban areas of Africa is poorly understood. This paper examines the extent and potential correlates of seasonal hunger in Malawi using panel data from 2011-2013. We find that both urban and rural households report seasonal hunger in the pre-harvest months.

The clinical presentation, utilization, and outcome of individuals with sickle cell anaemia presenting to urban emergency department of a tertiary hospital in Tanzania.

Background: Sickle cell anaemia (SCA) is prevalent in sub-Saharan Africa, with high risk of complications requiring emergency care. There is limited information about presentation of patients with SCA to hospitals for emergency care. We describe the clinical presentation, resource utilization, and outcomes of SCA patients presenting to the emergency department (ED) at Muhimbili National Hospital (MNH) in Dar es Salaam, Tanzania.

Behavioral immune system activity predicts downregulation of chronic basal inflammation.

Here, we present a mechanistically grounded theory detailing a novel function of the behavioral immune system (BIS), the psychological system that prompts pathogen avoidance behaviors. We propose that BIS activity allows the body to downregulate basal inflammation, preventing resultant oxidative damage to DNA and promoting longevity. Study 1 investigated the relationship between a trait measure of pathogen avoidance motivation and in vitro and in vivo proinflammatory cytokine production.

Utilization of injury care case studies: a systematic review of the World Health Organization's "Strengthening care for the injured: Success stories and lessons learned from around the world".

Objective: Translation of evidence to practice is a public health priority. Worldwide, injury is a leading cause of morbidity and mortality. Case study publications are common and provide potentially reproducible examples of successful interventions in healthcare from the patient to systems level.

Review of referral criteria to lipid clinics and outcomes of treatment in four UK centres.

Background: Little data exist on the referral patterns and effectiveness of lipid clinics.

Methods: An audit was conducted in four clinics of 100 consecutive referrals each. Data were recorded on referral criteria, cardiovascular disease (CVD) risk factors, drug history, investigations, diagnoses, therapies, results and referrals.

First Dark Matter Constraints from a SuperCDMS Single-Charge Sensitive Detector.

We present the first limits on inelastic electron-scattering dark matter and dark photon absorption using a prototype SuperCDMS detector having a charge resolution of 0.1 electron-hole pairs (CDMS HVeV, a 0.93 g CDMS high-voltage device).

Labeling of Phosphatidylinositol Lipid Products in Cells through Metabolic Engineering by Using a Clickable myo-Inositol Probe.

Phosphatidylinositol (PI) lipids control critical biological processes, so aberrant biosynthesis often leads to disease. As a result, the capability to track the production and localization of these compounds in cells is vital for elucidating their complex roles. Herein, we report the design, synthesis, and application of clickable myo-inositol probe 1 a for bioorthogonal labeling of PI products.

Development of a simple, practice-based tool to assess quality of paediatric emergency care delivery in resource-limited settings: identifying critical actions via a Delphi study.

Objective: Provision of timely, high-quality care for the initial management of critically ill children in African hospitals remains a challenge. Monitoring the completion of critical actions during resuscitations can inform efforts to reduce variability and improve outcomes. We sought to develop a practice-based tool based on contextually relevant actions identified via a Delphi process.

A dust-enshrouded tidal disruption event with a resolved radio jet in a galaxy merger.

Tidal disruption events (TDEs) are transient flares produced when a star is ripped apart by the gravitational field of a supermassive black hole (SMBH). We have observed a transient source in the western nucleus of the merging galaxy pair Arp 299 that radiated >1.5 × 10 erg at infrared and radio wavelengths but was not luminous at optical or x-ray wavelengths.

Posttraumatic Deep Vein Thrombosis in Collegiate Athletes: An Exploration Clinical Case Series.

Background:   Although athletes are typically at low risk for developing venous thromboembolism (VTE), injured and noninjured athletes alike can be exposed to many acquired risk factors, including intense training, dehydration, trauma, immobilization, oral contraceptive use, and long-distance travel. Additionally, the risk of developing VTE might be increased by unidentified genetic clotting disorders. Due to the potential for fatal outcomes, knowledge of VTE pathoetiology and recognition of deep vein thrombosis (DVT) presentation should be an inherent part of the evaluation process for all who attend to athletes, regardless of age and apparent risk profile.

Differential diagnosis for chronic hypokalaemia.

Doctors will often see patients with chronic hypokalaemia, frequently this is secondary to gastrointestinal losses, diuretics or renal disease. However, in this case report we review a rarer cause of chronic hypokalaemia-Gitelman syndrome (GS).GS is an uncommon genetic disorder which causes primary renal tubular hypokalaemic metabolic alkalosis with secondary hypomagnesaemia and hypocalciuria.

Candida albicans Cannot Acquire Sufficient Ethanolamine from the Host To Support Virulence in the Absence of Phosphatidylethanolamine Synthesis.

mutants for phosphatidylserine (PS) synthase (ΔΔ) and PS decarboxylase (ΔΔ ΔΔ) are compromised for virulence in mouse models of systemic infection and oropharyngeal candidiasis (OPC). Both of these enzymes are necessary to synthesize phosphatidylethanolamine (PE) by the pathway, but these mutants are still capable of growth in culture media, as they can import ethanolamine from media to synthesize PE through the Kennedy pathway. Given that the host has ethanolamine in its serum, the exact mechanism by which virulence is lost in these mutants is not clear.

Understanding Patient Questions about their Medical Records in an Online Health Forum: Opportunity for Patient Portal Design.

There are many benefits of online patient access to their medical records through technologies such as patient portals. However, patients often have difficulties understanding the clinical data presented in portals. In response, increasingly, patients go online to make sense of this data.
