Mitochondria and the endoplasmic reticulum (ER) are fundamental organelles that coordinate high-order cell functions. Mitochondria are centers of energy production, whereas the ER is responsible for folding, transport, and degradation of proteins. In addition to their specific functions, mitochondria and ER actively communicate with each other to promote a variety of cellular events, such as material transfer and signal transduction. Recent studies have shown the critical involvement of these organelles in regulation of the innate immune system, which functions in host defense...

Prompt antiretroviral therapy (ART) initiation maximises the therapeutic and prevention benefits of a treat-all strategy for HIV therapy. Using in-depth semi-structured interviews with men and women 18 years and older (N = 41), who were highly motivated and seeking treatment, this study examined salient factors that were associated with delays in treatment access and initiation. Results revealed clinic-related barriers including an onerous, inefficient multi-step process to initiate ART. Participants experienced additional delays due to difficulties accessing care (e...

REVIEW
S Burger-Stritt, S Hahner
Patients with chronic adrenal insufficiency suffer from reduced quality of life and increased mortality. An association between mortality and adrenal crisis is assumed. The frequency of adrenal crisis is about 8/100 patient years. The main causes are infectious disease. Pathophysiology is poorly understood to date. An association with an exaggerated inflammatory response due to a lack of glucocorticoid modulation as well as mineralocorticoid deficiency and diminished adrenomedullary function are discussed. The therapy of adrenal crisis includes prompt parenteral administration of hydrocortisone combined with isotonic saline...

Bing Wang, Qian Yin
Absent in melanoma 2 (AIM2) inflammasome is a multi-protein platform that recognizes aberrant cytoplasmic dsDNA and induces cytokine maturation, release and pyroptosis. It is composed of AIM2, apoptosis-associated speck-like protein containing a CARD (ASC), and caspase-1. Recent X-ray crystallographic and high resolution cryo-electron microscopic (cryo-EM) studies have revealed a series of structures in AIM2 inflammasome activation and regulation. One prominent feature common in multiple steps is the assembly of high-order structures, especially helical filaments nucleated by upstream molecules, rather than stoichiometric complexes...

BACKGROUND: Adenoma detection rate (ADR) is a quality indicator for screening colonoscopy, but its calculation is time-consuming. Polyp detection rate (PDR) has been found to correlate with ADR; however, its use as a quality indicator has been criticized out of concern for endoscopists artificially inflating the PDR. We aim to evaluate whether active monitoring affects PDR. METHODS: In March 2015, 14 endoscopists were made aware that their personal PDRs would be tracked monthly as a quality improvement project...

OBJECTIVE: Extracorporeal membrane oxygenation within CPR (ECPR) may improve survival for refractory out-of-hospital cardiac arrest (OHCA). We developed a prehospital, emergency department (ED), and hospital-based clinical and educational protocol to improve the key variable of time-to-ECPR (TTE). METHODS: In a single urban health region we involved key prehospital, clinical, and administrative stakeholders over a 2-year period, to develop a regional ECPR program with destination to a single urban tertiary care hospital...

In this paper, we discuss the ability to numerically minimize the grand potential of hard disks in two-dimensional and of hard spheres in three-dimensional space within the framework of classical density functional and fundamental measure theory on modern graphics cards. Our main finding is that a massively parallel minimization leads to an enormous performance gain in comparison to standard sequential minimization schemes. Furthermore, the results indicate that in complex multi-dimensional situations, a heavy parallel minimization of the grand potential seems to be mandatory in order to reach a reasonable balance between accuracy and computational cost...

OBJECTIVES: The evaluation of iatrogenic dentinal defects in extracted teeth may be influenced by extraction forces and prolonged dry times. The purpose of this study was to compare the presence of dentinal defects in freshly extracted, periodontally compromised teeth with those in a group of teeth with uncontrolled extraction forces and storage time. MATERIALS AND METHODS: The experimental group consisted of eighteen roots obtained from teeth extracted due to periodontal reasons with class II or III mobility...

Haemonchus contortus resistant to multiple anthelmintics threaten the viability of the small ruminant industry in areas where this parasite is prevalent. In response to this situation, the FAMACHA© system was developed and validated for use with small ruminants as a way to detect clinical anemia associated with haemonchosis. Given that H. contortus and multiple anthelmintic resistance is a similar problem in camelids, the FAMACHA© system might also provide the same benefits. To address this need, a validation study of the FAMACHA© system was conducted on 21 alpaca and llama farms over a 2-year period...

Ensuring the sustained immunization of displaced persons is a key objective in humanitarian emergencies. Typically, humanitarian actors measure coverage of single vaccines following an immunization campaign; few measure routine coverage of all vaccines. We undertook household surveys of Syrian refugees in Jordan and Lebanon, outside of camps, using a mix of random and respondent-driven sampling, to measure coverage of all vaccinations included in the host country's vaccine schedule. We analyzed the results with a critical eye to data limitations and implications for similar studies...

BACKGROUND: There is a need for interventions that effectively reduce compulsory admission to psychiatry. We conducted a randomised controlled trial to investigate whether an innovative intervention programme prevents compulsory re-admission in people with serious mental illness. METHODS: The programme addresses primarily patients' self-management skills. It consists of individualised psychoeducation focusing on behaviours prior to and during illness-related crises, crisis cards and, after discharge from the psychiatric hospital, a 24-month preventive monitoring...

As faces become familiar, we come to rely more on their internal features for recognition and matching tasks. Here, we assess whether this same pattern is also observed for a card sorting task. Participants sorted photos showing either the full face, only the internal features, or only the external features into multiple piles, one pile per identity. In Experiments 1 and 2, we showed the standard advantage for familiar faces-sorting was more accurate and showed very few errors in comparison with unfamiliar faces...

Seven cases and a quality assurance test are presented. In these cases, fibres or textiles submitted for investigation were analysed by HPLC-DAD-MS to identify the dyes present. The cases presented illustrate that it is possible to identify textile dyes in fibre traces recovered for forensic analysis. The results show that a mixture of dyes is present in all textiles investigated, except one sample that was taken from a manufacturer dye shade card. It is concluded that dye analyses improves the evidential value of forensic fibre examinations, as it becomes possible to distinguish textiles that are different in dye chemistry, but have a similar colour...

AIM OF THE STUDY: The purpose of this study was to examine continuous oxygen insufflation (COI) in a swine model of cardiac arrest. The primary hypothesis was COI during standard CPR (S-CPR) should result in higher intrathoracic pressure (ITP) during chest compression and lower ITP during decompression versus S-CPR alone. These changes with COI were hypothesized to improve hemodynamics. The second hypothesis was that changes in ITP with S-CPR+COI would result in superior hemodynamics compared with active compression decompression (ACD) + impedance threshold device (ITD) CPR, as this method primarily lowers ITP during chest decompression...

Distinct cognitive deficits have been described in Bipolar disorder (BD), including executive impairments, commonly attributed to frontal dysfunction. However, recent attention has been paid to the heterogeneity of cognitive functioning in this population, suggesting that the executive deficits observed in BD might be due to a loss in fluid intelligence (g). Following our previous line of investigation in multiple neurological and psychiatric conditions we aimed at determining the role of g in frontal deficits in BD...

BACKGROUND: Although cognitive deficits in bipolar disorder (BD) have been repeatedly observed, our understanding of these impairments at a mechanistic level remains limited. Few studies that investigated cognitive impairments in bipolar illness have examined the association with brain biochemistry. This pilot study utilized proton magnetic resonance spectroscopy ((1)H-MRS) to evaluate the relationship between neurocognitive performance and brain metabolites in youth with BD. METHODS: Thirty participants, twenty depressed BD participants and ten healthy comparison participants, ages 13-21, completed mood and executive function measures...

The challenges of delivering healthcare within budget constraints are ever present. Highly specialised technologies (HSTs) have high costs of provision inevitably contributing to NHS cost pressures. Between 2012-2015 the Welsh Health Specialised Services Committee (WHSSC) developed prioritisation methods to make recommendations for HST funding in Wales. Methods adapted as the process continued but was always evidence based and supported by a prioritisation panel of stakeholders. Methods changed from discreet choice to the Portsmouth Score Card, a simple multi-criteria decision analysis (MCDA) method...

Prevention of mother-to-child transmission (PMTCT) guidelines recommend that all HIV-infected pregnant woman receive antiretroviral therapy (Option B) and HIV-infected infants should initiate therapy with a protease inhibitor based regimen; however, implementation of these guidelines has lagged in many resource-limited settings. Tanzania only recently implemented these guidelines with little country specific data to inform whether HIV non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance was present among infected infants under the Option A guidelines...

BACKGROUND: In 2000, American Samoa had 16.5% prevalence of lymphatic filariasis (LF) antigenemia. Annual mass drug administration (MDA) was conducted using single-dose albendazole plus diethylcarbamazine from 2000 to 2006. This study presents the results of a 2007 population-based PacELF C-survey in all ages and compares the adult filarial antigenemia results of this survey to those of a subsequent 2010 survey in adults with the aim of improving understanding of LF transmission after MDA...
