BACKGROUND: Despite widespread use of the 250-mcg Cosyntropin test (ACTH test) for the diagnosis of adrenal insufficiency (AI), the effect of time of day and the utility of performing both 30- and 60-min serum cortisol values remains unclear. METHODS: We conducted a retrospective cohort study of all ACTH testing at the Halifax Neuropituitary Program, Nova Scotia, Canada between January 2006 and April 2016. Data were collected on age, gender, medication history, serum cortisol levels at 0, 30 and 60 min after ACTH administration, as well as time of and indication for testing...

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is rare in children and is characterised as necrotising vasculitis predominantly affecting small and medium-sized vessels. Propylthiouracil (PTU), an antithyroid drug, has been implicated in drug-induced AAV. In contrast, Kawasaki disease (KD) is a common systemic vasculitis, typically observed in children, which affects the medium-sized vessels, including the coronary arteries. An 11-year-old girl who developed AAV while receiving PTU therapy for Graves' disease is described...

Epithelial-mesenchymal transition (EMT) promotes invasion and metastasis of pancreatic ductal adenocarcinoma (PDAC). However, the importance of its reverse process, mesenchymal-epithelial transition (MET), for PDAC remains unclear. We aimed to characterize the histological finding "focal differentiation" in PDAC at perineural invasion sites in the context of MET and to investigate the role of Schwann cells in inducing tumor MET. Tumor differentiation and immunohistochemical expressions of E-cadherin, SMAD3, and vimentin at perineural invasion sites were examined in 168 PDAC tissues...

Crystallography has shown that human blood group A (GTA) and B (GTB) glycosyltransferases undergo transitions between "open", "semi-closed", and "closed" conformations upon substrate binding. However, the time scales of corresponding conformational reorientations are unknown. Crystal structures show that Trp and Met residues are located at "conformational hot spots" of the enzymes. Therefore, we have utilized 15N-side chain labeling of Trp residues, and 13C-methyl labeling of Met residues to study substrate induced conformational transitions of GTB...

Madison Sunnquist, Leonard A Jason
OBJECTIVE: The cognitive behavioral model of chronic fatigue syndrome (CFS) suggests that cognitions and reduced activity level perpetuate the fatigue and impairment that individuals with CFS experience. The two empirical evaluations of this model resulted in conflicting findings. The current study examines the influence of case definition fulfillment on the applicability of this model to CFS. METHOD: A moderated mediation analysis was conducted on 990 individuals with CFS to reexamine the behavioral pathway of this model...

REVIEW
Mimi Arandjelovic, Linda Vigilant
Knowing the density or abundance of primate populations is essential for their conservation management and contextualizing socio-demographic and behavioral observations. When direct counts of animals are not possible, genetic analysis of non-invasive samples collected from wildlife populations allows estimates of population size with higher accuracy and precision than is possible using indirect signs. Furthermore, in contrast to traditional indirect survey methods, prolonged or periodic genetic sampling across months or years enables inference of group membership, movement, dynamics, and some kin relationships...

This study was performed to investigate the effect of cochlear implantation on the Quality of Life (QoL) of children with profound and multiple learning disability (PMLD). This cohort of children has been viewed historically as poor candidates for cochlear implantation as they generally have poor speech and hearing outcomes. The Irish National Cochlear Implant Program's prospectively maintained database was examined for all children implanted from July 1996 to July 2015. All charts of the 381 children implanted during this time were reviewed retrospectively; 16 children met criteria for being PMLD...

Background: Because there is ongoing population aging, the age of patients admitted to the intensive care unit (ICU) is also higher. However, the evidence about outcomes in elderly patients is insufficient in Japan. Therefore, we conducted a retrospective study. Method: The study participants were consecutive patients who were admitted to our ICU and received mechanical ventilation for more than 24 h. We divided the patients into two groups, according to age. Patients in group A were 74 years old or younger, and those in group B were 75 years old or older...
