OBJECTIVES: Researchers have argued that leadership is one of the most important determinants of team effectiveness. The present study examined the extent to which the perceived quality of athlete leadership was related to the effectiveness of elite sports teams. DESIGN: Three professional football teams (N=135) participated in our study during the preparation phase for the Australian 2016 season. METHODS: Players and coaching staff were asked to assess players' leadership quality in four leadership roles (as task, motivational, social, and external leader) via an online survey...

PurposeSuspicious neoplastic conjunctival lesions often require wide excision with tumour-free margins, leaving significant conjunctival defects requiring reconstruction. In this study we report the results of using fresh frozen amniotic membrane grafts (AMG) after wide excision of potentially malignant lesions.MethodsRetrospective review of 53 patients; between January 2011 and April 2014. Conjunctival lesions were excised with a non-touch technique (2 mm margin) and sent for histopathological analysis. The surgical margins were treated with cryotherapy and a fresh frozen AMG was used to cover the defect...

A literature review was conducted, using the computerized "Online Mendelian Inheritance in Man" (OMIM) and PubMed, to identify inborn errors of metabolism (IEM) in which psychosis may be a predominant feature or the initial presenting symptom. Different combinations of the following keywords were searched using OMIM: "psychosis", "schizophrenia", or "hallucinations" and "metabolic", "inborn error of metabolism", "inborn errors of metabolism", "biochemical genetics", or "metabolic genetics". The OMIM search generated 126 OMIM entries, 40 of which were well known IEM...

Lysine-specific demethylase 1 (LSD1) regulates gene expression by affecting histone modifications and is a promising target for acute myeloid leukemia (AML) with specific genetic abnormalities. Novel LSD1 inhibitors, NCD25 and NCD38, inhibited growth of MLL-AF9 leukemia as well as erythroleukemia, megakaryoblastic leukemia and myelodysplastic syndromes (MDS) overt leukemia cells in the concentration range that normal hematopoiesis was spared. NCD25 and NCD38 invoked the myeloid development programs, hindered the MDS and AML oncogenic programs, and commonly upregulated 62 genes in several leukemia cells...

The therapeutic landscape of multiple myeloma (MM) has evolved spectacularly over the past decade with the discovery and validation of proteasome inhibitors and immunomodulatory agents as highly active agents, both in front-line therapy as well as in the relapse and maintenance settings. While previous attempts to apply available monoclonal antibodies (Mabs) to the treatment of patients with MM has until recently been disappointing, novel targets specifically explored in the context of MM have recently lead to the first approvals of Mabs for the treatment of patients with MM...

Beals syndrome, also known as congenital contractural arachnodactyly (Online Mendelian Inheritance in Man: 121050), is an autosomal dominant disorder caused by a mutation in FBN2 that is typically characterized by congenital contractures and arachnodactyly. It shares a number of phenotypic features with Loeys-Dietz syndrome (Online Mendelian Inheritance in Man: 609192). Loeys-Dietz syndrome, initially described in 2005, is associated with mutations for the transforming growth factor β receptor and is characterized by findings of cerebral, thoracic, and abdominal arterial aneurysms...

BACKGROUND: The psychological mechanisms of why individuals with negative symptoms fail to initiate and perform goal-directed behavior are not well understood. Drawing on the reward-sensitivity and expectancy-value theories, we investigate whether negative symptom-like experiences (NSLE) are associated with generating less approach goals (aimed at reaching a positive outcome) and more avoidance goals (aimed at avoiding a negative outcome) and whether this type of goal-orientation explains motivational deficits (i...

Nonaqueous capillary electrophoresis (NACE) is very well suited for online coupling with mass spectrometry due to the relatively high volatility and low surface tension of most organic solvents. Here we present a quantitative NACE-ESI-MS/MS method for separating and determining physcion, chrysophanol, and aloe-emodin in rhubarb. Dantron was used as an internal standard to ensure accuracy and reproducibility in quantitative analyses. Parameters including the pH, background electrolyte (BGE) composition, flow-through microvial chemical modifier solution composition, and modifier solution flow rate were carefully optimized...

We describe the patterns of coverage gains associated with the Affordable Care Act (ACA) expansions and use these patterns to assess the potential impact of alternative repeal or repeal and replace strategies because Congress and the president are weighing options to repeal or replace the ACA. We find that specific provisions of the ACA, including the Medicaid expansion and the structure of premium subsidies, have been associated with large and robust gains in insurance coverage. We evaluate the impact of retaining dependent coverage and high-risk pool provisions and show, on the basis of the ACA experience, that these provisions would have little effect on coverage...

OBJECTIVES: To compare the predictive power of synthetic absolute income measures with that of asset-based wealth quintiles in low- and middle-income countries (LMICs) using child stunting as an outcome. METHODS: We pooled data from 239 nationally representative household surveys from LMICs and computed absolute incomes in US dollars based on households' asset rank as well as data on national consumption and inequality levels. We used multivariable regression models to compare the predictive power of the created income measure with the predictive power of existing asset indicator measures...

OBJECTIVES: To examine whether access to housing assistance is associated with better health among low-income adults. METHODS: We used National Health Interview Survey data (1999-2012) linked to US Department of Housing and Urban Development (HUD) administrative records (1999-2014) to examine differences in reported fair or poor health and psychological distress. We used multivariable models to compare those currently receiving HUD housing assistance (public housing, housing choice vouchers, and multifamily housing) with those who will receive housing assistance within 2 years (the average duration of HUD waitlists) to account for selection into HUD assistance...

BACKGROUND: Mental health and HIV disparities are well documented among sexual minorities, but there is a dearth of research on other chronic conditions. Cardiovascular disease remains the leading cause of death worldwide. Although sexual minorities have high rates of several modifiable risk factors for cardiovascular disease (including stress, tobacco use, and alcohol consumption), there is a paucity of research in this area. OBJECTIVES: In this systematic review, we synthesized and critiqued the existing evidence on cardiovascular disease among sexual minority adults...

PURPOSE: Up to 1% of all men experience azoospermia, a condition of complete absence of sperm in the semen. The mechanisms and genes involved in spermatogenesis are mainly studied in model organisms, and their relevance to humans is unclear because human genetic studies are very scarce. Our objective was to uncover novel human mutations and genes causing azoospermia due to testicular meiotic maturation arrest. METHODS: Affected and unaffected siblings from three families were subjected to whole-exome or whole-genome sequencing, followed by comprehensive bioinformatics analyses to identify mutations suspected to cause azoospermia...

Statistics show that veterinary surgeons are in one of the professions with the highest suicide rates. This indicates the sector has significant well-being issues, with high levels of occupational stress and burnout. Previous research has focused on environmental factors in isolation, overlooking the influence of personality. This study aimed to establish that personality is a better predictor of occupational stress than environment. UK veterinary surgeons (n=311) completed an online survey composed of three questionnaires; the NEO Five-Factor Inventory, the Maslach Burnout Inventory, and the Job Stress Survey...

Research shows that digital social network sites (SNSs) may be valuable platforms to effect health behavior change. Little is known specifically about their ability to help address alcohol and other drug problems. This gap is noteworthy, given that individuals are already participating in existing, recovery-specific SNSs (hereafter referred to as recovery SNSs): online communities with the functionality of conventional SNSs (e.g., Facebook) that focus on substance use disorder (SUD) recovery. For example, InTheRooms...

Autoimmune Th1 and Th17 responses are critical for the development of central nervous system (CNS) pathology in experimental autoimmune encephalomyelitis (EAE), an animal model for human multiple sclerosis. Although macrophages play important roles in the development of Th1 and Th17 responses, whether modulating macrophage gene transcription can diminish Th1- and Th17 cell-induced CNS pathology is unclear. In this study, we successfully silenced the expression of the transcription factor c-Rel in macrophages of mice with EAE (including those infiltrating the CNS) using chemically modified c-Rel-specific siRNAs delivered by nanoparticles...
