BACKGROUND AND OBJECTIVES: Symptoms of depression are highly prevalent among individuals with gambling disorder, and severity of depression is associated with severity of gambling problem. Yet, little is known about the psychological mechanisms by which symptoms of depression lead to greater gambling severity. In this study, we tested whether cognitive distortions represent one such mechanism, as cognitive distortions are key characteristics in both depression and gambling disorder and have been shown to be associated with gambling severity...

Stunting (length-for-age z score < -2) before 2 years of age has shown associations with poor child developmental indicators, but information at the population level is scarce in South Asia, the region with the highest burden of stunting. We examined associations between z scores (i.e., height for age [HAZ], weight for age [WAZ], and weight for height [WHZ]) and undernutrition (i.e., stunting [HAZ < -2], wasting [WHZ < -2], and underweight [WAZ < -2]) with learning/cognition and social-emotional development among children 36-59 months of age...

BACKGROUND: Biannual vitamin A supplementation is a well-established survival tool for preschool children 6 months and older in vitamin A deficient populations but this schedule misses the opportunity to intervene on most young infant deaths. Randomised trials of neonatal vitamin A supplementation (NVAS) in the first few days of life to assess its impact on under 6-month mortality in low/middle-income countries have had varying results. METHODS: Investigators of 11 published randomised placebo-controlled NVAS trials (n=163 567 children) reanalysed their data according to an agreed plan and pooled the primary outcomes of mortality from supplementation through 6 and 12 months of age using random effects models and meta-regression...

Lung transplantation can improve quality of life and prolong survival for individuals with end-stage lung disease, and many advances in the realms of both basic science and clinical research aspects of lung transplantation have emerged over the past few decades. However, many challenges must yet be overcome to increase post-transplant survival. These include successfully bridging patients to transplant, expanding the lung donor pool, inducing tolerance, and preventing a myriad of post-transplant complications that include primary graft dysfunction, forms of cellular and antibody-mediated rejection, chronic lung allograft dysfunction, and infections...

BACKGROUND: Surveillance magnetic resonance imaging (MRI) is routinely used to detect recurrence in children with high-grade central nervous system (CNS) tumors, although no consensus has been reached regarding its effectiveness and whether earlier detection is associated with improved patient outcomes. This review aimed to evaluate this practice and any associated benefits and harms. METHODS: Systematic searches for relevant studies were undertaken in a number of databases, including MEDLINE and EMBASE, from 1985 to August 2018...

Pseudomonas aeruginosa utilizes the Type II secretion system (T2SS) to translocate a wide range of large, structured protein virulence factors through the periplasm to the extracellular environment for infection. In the T2SS, five pseudopilins assemble into the pseudopilus that acts as a piston to extrude exoproteins out of cells. Through structure determination of the pseudopilin complexes of XcpVWX and XcpVW and function analysis, we have confirmed that two minor pseudopilins, XcpV and XcpW, constitute a core complex indispensable to the pseudopilus tip...

Antigen recognition by the T cell receptor (TCR) directs the assembly of essential signaling complexes known as SLP-76 (also known as LCP2) microclusters. Here, we show that the interaction of the adhesion and degranulation-promoting adaptor protein (ADAP; also known as FYB1) with SLP-76 enables the formation of persistent microclusters and the stabilization of T cell contacts, promotes integrin-independent adhesion and enables the upregulation of CD69. By analyzing point mutants and using a novel phospho-specific antibody, we show that Y595 is essential for normal ADAP function, that virtually all tyrosine phosphorylation of ADAP is restricted to a Y595-phosphorylated (pY595) pool, and that multivalent interactions between the SLP-76 SH2 domain and its binding sites in ADAP are required to sustain ADAP phosphorylation...

Exposure of P. aeruginosa to the aminoglycoside (AG) paromomycin (PAR) induced expression of the PA3720-armR locus and the mexAB-oprM multidrug efflux operon that AmgR controls, although PAR induction of mexAB-oprM was independent of armR. Multiple AGs promoted mexAB-oprM expression and this was lost in the absence of the amgRS locus encoding an aminoglycoside-activated envelope stress-responsive 2-component system (TCS). Purified AmgR bound to the mexAB-oprM promoter region consistent with this response regulator directly regulating expression of the efflux operon...

Adverse childhood experiences (ACEs) have been linked to numerous negative physical and mental health outcomes across the lifespan. As such, self-report questionnaires that assess for ACEs are increasingly used in healthcare settings. However, previous research has generated some concern over the reliability of retrospective reports of childhood adversity, and it has been proposed that symptoms of depression may increase recall of negative memories. To investigate the stability of ACE scores over time and whether they are influenced by symptoms of depression, we recruited 284 participants (M age = 40...

BACKGROUND: Evidence regarding whether imaging can be used effectively to select patients for endovascular thrombectomy (EVT) is scarce. We aimed to investigate the association between baseline imaging features and safety and efficacy of EVT in acute ischaemic stroke caused by anterior large-vessel occlusion. METHODS: In this meta-analysis of individual patient-level data, the HERMES collaboration identified in PubMed seven randomised trials in endovascular stroke that compared EVT with standard medical therapy, published between Jan 1, 2010, and Oct 31, 2017...

Two post hoc analyses in self-identified black and white patients with hypertension evaluated the angiotensin II receptor blocker azilsartan medoxomil (AZL-M) and the fixed-dose combination of AZL-M with chlorthalidone (AZL-M/CLD) versus the ARB olmesartan (OLM) and the OLM fixed-dose combination with hydrochlorothiazide (OLM/HCTZ). One analysis pooled 1,610 patients from two 6-week randomized controlled trials to compare once daily AZL-M 40 mg, AZL-M 80 mg, OLM 40 mg, and placebo. The second analysis included 1,020 patients from a 12-week randomized controlled trial to compare once daily AZL-M/CLD 40/25 mg, AZL-M/CLD 80/25 mg, and OLM/HCTZ 40/25 mg...

The discovery of mammalian cardiac progenitor cells has suggested that the heart consists of not only terminally differentiated beating cardiomyocytes, but also a population of self-renewing stem cells with the potential to generate new cardiomyocytes (Anderson, Self et al. 2007; Bearzi, Rota et al. 2007; Wu, Chien et al. 2008). A consequence of longevity is continual exposure to environmental and xenobiotic stresses, and recent literature suggests that hematopoietic stem cell pools tightly control cell health through upregulation of the integrated stress response and consequent cellular mechanisms such as apoptosis...

BACKGROUND: Cerebral palsy (CP) comprises a heterogeneous group of disorders whose clinical manifestations and epidemiologic characteristics vary across socioeconomic and geographic contexts. The functional severity of untreated CP in low-income countries has been insufficiently studied; a better understanding of how these children present for care in resource-constrained environments is important because it will better characterize the natural history of CP, guide clinical decision-making, and aid in the prognostication of children with untreated CP...

Similarity between narcissism and self-esteem seems intuitive, as both capture positive perceptions of the self. In the current undertaking, we provide a broad comparison of the nomological networks of grandiose narcissism and explicit self-esteem. Pooling data from 11 existing samples (N = 4711), we compared the relations of narcissism and self-esteem to developmental experiences, individual differences, interpersonal functioning, and psychopathology. Both constructs are positively related to agentic traits and assertive interpersonal approaches, but differ in relation to agreeableness/communion...
