INTRODUCTION: Generalised anxiety disorder (GAD) and subclinical GAD are highly prevalent in primary care. Unmanaged anxiety worsens quality of life in patients seen in primary care practices and leads to increased medical utilisation and costs. Programmes that teach patients cognitive-behavioural therapy (CBT) techniques have been shown to improve anxiety and to prevent the evolution of anxiety symptoms to disorders, but access and engagement have hampered integration of CBT into medical settings...

OBJECTIVE: Quality monitoring of assessment practices should be a priority in all residency programs. Validity evidence is one of the main hallmarks of assessment quality and should be collected to support the interpretation and use of assessment data. Our objective was to identify, synthesize, and present the validity evidence reported supporting different technical skill assessment tools in otolaryngology-head and neck surgery (OTL-HNS). METHODS: We performed a secondary analysis of data generated through a systematic review of all published tools for assessing technical skills in OTL-HNS (n = 16)...

Venous thromboembolism (VTE) is a major cause of morbidity and mortality in the United States. Hospitalized, medically ill older adults have increased risk; despite guidelines, data suggest suboptimal pharmacologic prophylaxis rates. Factors influencing provider prescribing non-compliance are unclear. We aimed to describe VTE prophylaxis practices and identify risk factors for, and outcomes of, prescribing non-compliance. A retrospective study was conducted of hospitalized adults aged ≥ 75 years, admitted to the medicine service of a large academic tertiary center from May 1, 2014 to June 30, 2015...

Sphingosine kinase 1 (SK1) is a key enzyme which regulates a multitude of cellular processes including cellular growth, immune cell trafficking, and inflammation via the production of sphingosine-1-phosphate (S1P). To produce S1P, SK1 must access sphingosine directly from membranes. Despite the need for membrane access, the molecular mechanisms underlying SK1s direct membrane interaction remain unclear. Here, we identify a novel positively charged site on SK1 which is responsible for electrostatic interactions with membranes...

Background: Cancer risk is increased in people living with HIV (PLWH). Improved survival has led to an aging of PLWH. We evaluated the cancer risk in older PLWH (age ≥50 years). Methods: We included data from the HIV/AIDS Cancer Match Study (1996-2012) and evaluated risk of Kaposi sarcoma (KS), non-Hodgkin lymphoma (NHL), Hodgkin lymphoma, and cervical, anal, lung, liver, oral cavity/pharyngeal, breast, prostate, and colon cancers in older PLWH compared to the general population by calculating the standardized incidence ratios (SIRs) and excess absolute risks (EARs)...

Chondromyxoid fibroma (CMF) is a rare benign tumor, usually arising in the metaphysis of long bones in young adults. Occurrence in craniofacial bones presents a particular diagnostic challenge given its unusual location and resemblance to malignant mimics. We describe the clinicopathologic features of 25 cases of craniofacial CMF identified between 1999 and 2017. Patients were 14 men and 11 women, with median age of 44 years (range, 5 to 83 y). Sites of involvement were sphenoid (7), ethmoid (5), maxilla (3), occipital (2), nasal septum (2), palatine (2), temporal (2), orbit (1), and undisclosed skull (1)...

The success of targeted covalent inhibitors in the global pharmaceutical industry has led to a resurgence of covalent drug discovery. However, covalent inhibitor design for flexible binding sites remains a difficult task due to lack of methodological development. Here, we compared covalent docking to empirical electrophile screening, against the highly dynamic target K-RasG12C. While the overall hit-rate of both methods was comparable, we were able to rapidly progress a docking hit to a potent irreversible covalent inhibitor that modifies the inactive, GDP-bound state of K-RasG12C...

Shyamal Desai, Meredith Juncker, Catherine Kim
Mitophagy is a cellular process by which dysfunctional mitochondria are degraded via autophagy. Increasing empirical evidence proposes that this mitochondrial quality-control mechanism is defective in neurons of patients with various neurodegenerative diseases such as Ataxia Telangiectasia, Alzheimer's disease, Parkinson's disease, and Amyotrophic Lateral Sclerosis. Accumulation of defective mitochondria and the production of reactive oxygen species due to defective mitophagy have been identified as causes underlying neurodegenerative disease pathogenesis...

Acquisition of multimodal brain imaging data for the same subject has become more common leading to a growing interest in determining the intermodal relationships between imaging modalities to further elucidate the pathophysiology of schizophrenia. Multimodal data have previously been individually analyzed and subsequently integrated; however, these analysis techniques lack the ability to examine true modality inter-relationships. The utilization of a multiset canonical correlation and joint independent component analysis (mCCA + jICA) model for data fusion allows shared or distinct abnormalities between modalities to be examined...

As part of the Reproducibility Project: Cancer Biology, we published a Registered Report (Blum et al., 2015), that described how we intended to replicate selected experiments from the paper 'Transcriptional amplification in tumor cells with elevated c-Myc' (Lin et al., 2012). Here we report the results. We found overexpression of c-Myc increased total levels of RNA in P493-6 Burkitt's lymphoma cells; however, while the effect was in the same direction as the original study (Figure 3E; Lin et al., 2012), statistical significance and the size of the effect varied between the original study and the two different lots of serum tested in this replication...

Person-centered care (PCC) is a central feature of health care reform, yet the tools needed to deliver this practice have not been implemented consistently. Person-centered care planning (PCCP) is a treatment planning approach operationalizing the values of recovery. To better understand PCCP implementation, this study examined the relationship between recovery knowledge and self-reported PCCP behaviors among 224 community mental health center staff. Results indicated that increased knowledge decreased the likelihood of endorsing non-recovery implementation barriers and self-reporting a high level of PCCP implementation...

Malignant pleural mesothelioma (MPM) is an aggressive tumor and the prognosis is still dismal despite the various proposed multimodal treatment plans. Currently, new palliative treatments, such as talc pleurodesis, are being explored besides traditional surgery. This review reports survival rates after talc pleurodesis in comparison to surgery in patients with malignant pleural mesothelioma. A systematic literature search yielded 49 articles eligible for this review. The mean survival in the talc pleurodesis group was 14 months compared to 17 and 24 months for the pleurectomy decortication (P/D) group and extrapleural pneumonectomy (EPP) group, respectively...

BACKGROUND: High hepatitis C cure rates have been observed in registration trials with second-generation direct-acting antivirals. Real-world data also indicate high sustained viral response (SVR) rates. Our objective was to determine real-world SVR rates for patients infected with hepatitis C virus (HCV) who were treated with second-generation direct-acting antivirals in the first 18 months of their availability in Canada. METHODS: Four centres in Calgary contributed their treatment data for a diverse patient population including those who had or had not undergone liver transplantation, those coinfected with HIV and vulnerable populations...

BACKGROUND: Systemic juvenile idiopathic arthritis (sJIA) is an auto-inflammatory disease characterized by fever, arthritis, and ≥1 of rash, generalized lymphadenopathy, hepato/splenomegaly, and serositis. Non-steroidal anti-inflammatory drugs (NSAIDs) are among the initial treatments of sJIA, but there is currently no evidence indicating which children should undergo a trial of NSAID monotherapy and which should not. Our objective is to identify presentation characteristics which are associated with response and lack of response to a trial of NSAID monotherapy...

Arabidopsis has been reported to respond to phosphate (Pi) stress by arresting primary root growth and increasing lateral root branching. We developed a system to buffer Pi availability to Arabidopsis in gel media systems by charging activated aluminum oxide particles with low and sufficient concentrations of Pi, based on previous work in horticultural and sand culture systems. This system more closely mimics soil chemistry and results in different growth and transcriptional responses to Pi stress compared with plants grown in standard gel media...
