The Role of Ultrasound Compared to Biopsy of Temporal Arteries in the Diagnosis and Treatment of Giant Cell Arteritis (TABUL): a diagnostic accuracy and cost-effectiveness study.

Background: Giant cell arteritis (GCA) is a relatively common form of primary systemic vasculitis, which, if left untreated, can lead to permanent sight loss. We compared ultrasound as an alternative diagnostic test with temporal artery biopsy, which may be negative in 9-61% of true cases.

Objective: To compare the clinical effectiveness and cost-effectiveness of ultrasound with biopsy in diagnosing patients with suspected GCA.

Multiple Origins of the Pathogenic Yeast Candida orthopsilosis by Separate Hybridizations between Two Parental Species.

Mating between different species produces hybrids that are usually asexual and stuck as diploids, but can also lead to the formation of new species. Here, we report the genome sequences of 27 isolates of the pathogenic yeast Candida orthopsilosis. We find that most isolates are diploid hybrids, products of mating between two unknown parental species (A and B) that are 5% divergent in sequence.

AAV-mediated gene delivery attenuates neuroinflammation in feline Sandhoff disease.

Sandhoff disease (SD) is a lysosomal storage disorder characterized by the absence of hydrolytic enzyme β-N-acetylhexosaminidase (Hex), which results in storage of GM2 ganglioside in neurons and unremitting neurodegeneration. Neuron loss initially affects fine motor skills, but rapidly progresses to loss of all body faculties, a vegetative state, and death by five years of age in humans. A well-established feline model of SD allows characterization of the disease in a large animal model and provides a means to test the safety and efficacy of therapeutic interventions before initiating clinical trials.

Chromosomal microarray testing in adults with intellectual disability presenting with comorbid psychiatric disorders.

Chromosomal copy-number variations (CNVs) are a class of genetic variants highly implicated in the aetiology of neurodevelopmental disorders, including intellectual disabilities (ID), schizophrenia and autism spectrum disorders (ASD). Yet the majority of adults with idiopathic ID presenting to psychiatric services have not been tested for CNVs. We undertook genome-wide chromosomal microarray analysis (CMA) of 202 adults with idiopathic ID recruited from community and in-patient ID psychiatry services across England.

Effects of Simultaneous Script Training on Use of Varied Mand Frames by Preschoolers with Autism.

Young children with autism may fail to mand using a range of frames (e.g., "I want," "May I have," "Please give me").

Comparative genomics of biotechnologically important yeasts.

Ascomycete yeasts are metabolically diverse, with great potential for biotechnology. Here, we report the comparative genome analysis of 29 taxonomically and biotechnologically important yeasts, including 16 newly sequenced. We identify a genetic code change, CUG-Ala, in Pachysolen tannophilus in the clade sister to the known CUG-Ser clade.

Centromeres of the Yeast Komagataella phaffii (Pichia pastoris) Have a Simple Inverted-Repeat Structure.

Centromere organization has evolved dramatically in one clade of fungi, the Saccharomycotina. These yeasts have lost the ability to make normal eukaryotic heterochromatin with histone H3K9 methylation, which is a major component of pericentromeric regions in other eukaryotes. Following this loss, several different types of centromere emerged, including two types of sequence-defined ("point") centromeres, and the epigenetically defined "small regional" centromeres of Candida albicans Here we report that centromeres of the methylotrophic yeast Komagataella phaffii (formerly called Pichia pastoris) are structurally defined.

Significance of positive selection and gene duplication in adaptive evolution: in memory of Austin L. Hughes.

In this minireview, we highlight the contributions of the late Austin L. Hughes to two areas of molecular evolution: the role of positive (Darwinian) selection, and the impact of gene duplications during genome evolution.

Prenatal Stress and the Cortisol Awakening Response in African-American and Caucasian Women in the Third Trimester of Pregnancy.

Objectives Prior studies have shown significant racial disparities in psychosocial stressors for pregnant women. One physiological mechanism by which prenatal stress is expressed is via the stress-sensitive hormone cortisol, which itself differs by race. In this study, we examine differences in cortisol awakening response (CAR) for African-American and Caucasian pregnant women during late pregnancy, particularly whether racial disparities are evident after accounting for measures of psychosocial stress.

Radiologic presentation of chronic granulomatous prostatitis mimicking locally advanced prostate adenocarcinoma.

We present a case of nonspecific granulomatous prostatitis (GP), a clinical mimic of prostate adenocarcinoma. A 54-year-old man presented with lower urinary tract symptoms and raised prostate-specific antigen. Magnetic resonance imaging showed features consistent with prostate cancer, including low T2-signal intensity in the peripheral and transition zones with signs of extracapsular extension.

Reach and representativeness of ethnic minority women in the Health Is Power Study: a longitudinal analysis.

Reach is a key factor in translating research to practical application. This study examined reach and representativeness of a multi-city, randomized controlled community health trial in African American (AA) and Hispanic or Latina (HL) women. Participants completed measures of demographics, body mass index (BMI), percent body fat, resting heart rate, and blood pressure followed by a run-in procedure and a randomization meeting.

Effect of Noninvasive Ventilation Delivered by Helmet vs Face Mask on the Rate of Endotracheal Intubation in Patients With Acute Respiratory Distress Syndrome: A Randomized Clinical Trial.

Importance: Noninvasive ventilation (NIV) with a face mask is relatively ineffective at preventing endotracheal intubation in patients with acute respiratory distress syndrome (ARDS). Delivery of NIV with a helmet may be a superior strategy for these patients.

Objective: To determine whether NIV delivered by helmet improves intubation rate among patients with ARDS.

Interrater Agreement on the Visual Analysis of Individual Tiers and Functional Relations in Multiple Baseline Designs.

Previous research on visual analysis has reported low levels of interrater agreement. However, many of these studies have methodological limitations (e.g.

From pole to pole: the potential for the Arctic seastar Asterias amurensis to invade a warming Southern Ocean.

Due to climatic warming, Asterias amurensis, a keystone boreal predatory seastar that has established extensive invasive populations in southern Australia, is a potential high-risk invader of the sub-Antarctic and Antarctic. To assess the potential range expansion of A. amurensis to the Southern Ocean as it warms, we investigated the bioclimatic envelope of the adult and larval life stages.

Spiritual coping, psychosocial adjustment, and physical health in youth with chronic illness: a meta-analytic review.

Objective: The current systematic review and meta-analysis aimed to assess the strength of the relationships between religious/spiritual coping strategies and psychosocial adjustment and physical health in youth with chronic illness.

Background: Faced with medical stressors and uncertainty about their illness, spiritual beliefs and behaviours are important for youth with chronic illness. Research suggests that some spiritual coping strategies are helpful (positive), while others are not (negative), and these dimensions of spiritual coping are important predictors of functioning among youth with chronic illness.

Reversal of ocean acidification enhances net coral reef calcification.

Approximately one-quarter of the anthropogenic carbon dioxide released into the atmosphere each year is absorbed by the global oceans, causing measurable declines in surface ocean pH, carbonate ion concentration ([CO3(2-)]), and saturation state of carbonate minerals (Ω). This process, referred to as ocean acidification, represents a major threat to marine ecosystems, in particular marine calcifiers such as oysters, crabs, and corals. Laboratory and field studies have shown that calcification rates of many organisms decrease with declining pH, [CO3(2-)], and Ω.

Risk of Procedural Hemorrhage.

Patients who are critically ill and hospitalized often require invasive procedures as a part of their medical care. Each procedure carries a unique set of risks and associated complications, but common to all of them is the risk of hemorrhage. Central venous catheterization, arterial catheterization, paracentesis, thoracentesis, tube thoracostomy, and lumbar puncture constitute a majority of the procedures performed in patients who are hospitalized.

Computer-assisted single-stage cranioplasty.

Cranioplasty treats and repairs cranial defects with a custom craniofacial implant (CCI). Typically, surgeons know the defect size prior to surgery. Recent efforts consider single-stage cranioplasty-performing the bony resection and fixating the CCI in a single operation.
