A significant proportion of children have unexplained problems acquiring proficient linguistic skills despite adequate intelligence and opportunity. Developmental language disorders are highly heritable with substantial societal impact. Molecular studies have begun to identify candidate loci, but much of the underlying genetic architecture remains undetermined. We performed whole-exome sequencing of 43 unrelated probands affected by severe specific language impairment, followed by independent validations with Sanger sequencing, and analyses of segregation patterns in parents and siblings, to shed new light on aetiology...

The widespread African clawed frog (Xenopus laevis) occurs in sympatry with the IUCN Endangered Cape platanna (Xenopus gilli) throughout its entire range in the south-western Cape, South Africa. In order to investigate aspects of the interspecific competition between populations of X. laevis and X. gilli, an assessment of their niche differentiation was conducted through a comprehensive study on food composition and trophic niche structure at two study sites: the Cape of Good Hope (CoGH) and Kleinmond. A total of 399 stomach contents of X...

Various non-invasive methods are available to measure cardiac output (CO) during pregnancy. We compared serial measures of CO using various methods to determine which provided the least variability. Ten patients with spontaneous pregnancy had estimation of CO at baseline prior to becoming pregnant and at the end of the first and third trimesters. Echocardiographic data were used to estimate CO using the Teichholz method, Simpson's biplane method, and the Doppler determined velocity time integral (VTI) method...

Donation physicians are specialists with expertise in organ and tissue donation and have been recognized internationally as a key contributor to improving organ and tissue donation services. Subsequent to a 2011 Canadian Critical Care Society-Canadian Blood Services consultation, the donation physician role has been gradually implemented in Canada. These professionals are generally intensive care unit physicians with an enhanced focus and expertise in organ/tissue donation. They must manage the dual obligation of caring for dying patients and their families while providing and/or improving organ donation services...

Care planning and co-ordination are central to the delivery of comprehensive mental health care especially where individuals have complex health and social care needs. Although the terms are often used together they clearly imply different sets of processes, practices and ultimately experiences for individuals using and working in services. Care planning involves professionals (nurses, doctors, social workers and others) and the person needing care collaborating on goals, making shared written records and agreeing when to review progress...

BACKGROUND: Of young people with first episode psychosis (FEP), over half report exposure to childhood trauma and consequent co-morbid post-traumatic stress disorder (PTSD) or symptoms. Currently no evidence-based interventions exist for PTSD in FEP. Clinicians report concerns that trauma-focused interventions with young people with FEP could result in distress and symptom exacerbation. Scant research suggests that talking about trauma in therapy can be distressing for some people. AIMS: To explore young people's reactions to a trauma-focused treatment for PTSD in FEP...

INTRODUCTION: A subpopulation of sickle-cell disease patients, termed super-utilizers, presents frequently to emergency departments (EDs) for vaso-occlusive events and may consume disproportionate resources without broader health benefit. To address the healthcare needs of this vulnerable patient population, we piloted a multidisciplinary intervention seeking to create and use individualized patient care plans that alter utilization through coordinated care. Our goals were to assess feasibility primarily, and to assess resource use secondarily...

In many animals intersegmental reflexes are important for postural and movement control but are still poorly undesrtood. Mathematical methods can be used to model the responses to stimulation, and thus go beyond a simple description of responses to specific inputs. Here we analyse an intersegmental reflex of the foot (tarsus) of the locust hind leg, which raises the tarsus when the tibia is flexed and depresses it when the tibia is extended. A novel method is described to measure and quantify the intersegmental responses of the tarsus to a stimulus to the femoro-tibial chordotonal organ...

Malignant spreading involves the migration of cancer cells amongst other native cell types. For example, in vivo melanoma invasion involves individual melanoma cells migrating through native skin, which is composed of several distinct subpopulations of cells. Here, we aim to quantify how interactions between melanoma and fibroblast cells affect the collective spreading of a heterogeneous population of these cells in vitro. We perform a suite of circular barrier assays that includes: (i) monoculture assays with fibroblast cells; (ii) monoculture assays with SK-MEL-28 melanoma cells; and (iii) a series of co-culture assays initiated with three different ratios of SK-MEL-28 melanoma cells and fibroblast cells...

BACKGROUND: Electrocardiographic (ECG) left ventricular hypertrophy (LVH) is a strong predictor of cardiovascular (CV) morbidity and mortality. However, the predictive value of ECG LVH in treated hypertensive patients remains unclear. METHODS: A total of 33,357 patients (aged ≥ 55 years) with hypertension and at least 1 other coronary heart disease (CHD) risk factor were randomized to chlorthalidone, amlodipine, or lisinopril. The outcome of the present study was all-cause mortality; and secondary endpoints were CHD, nonfatal myocardial infarction (MI), stroke, angina, heart failure (HF), and peripheral arterial disease...

Secretion of high molecular weight (HMW) adiponectin is dependent on post-translational modification (PTM) of conserved lysines in the collagenous domain. This work aims to characterize the enzymes responsible for the PTM of conserved lysines which leads to HMW adiponectin secretion, and to define its significance in relation to obesity.  Collagen beta (1- O ) galactosyltransferase 1 (GLT25D1) was knocked down in HEK cells modified for the stable expression of adiponectin (Adipo-HEK cells) as well as in Simpson Golabi-Behmel-Syndrome (SGBS) adipocytes...

BACKGROUND: Childbirth is a leading reason for hospital admission in the USA, and most labour care is provided by registered nurses under physician or midwife supervision in a nurse-managed care model. Yet, there are no validated nurse-sensitive quality measures for maternity care. We aimed to engage primary stakeholders of maternity care in identifying the aspects of nursing care during labour and birth they believe influence birth outcomes, and how these aspects of care might be measured...

BACKGROUND: Naturally acquired immunity can reduce parasitaemia and potentially influence anti-malarial treatment outcomes; however, evidence for this in the current literature provides conflicted results. The available evidence was synthesized to determine and quantify the association between host immunity and anti-malarial treatment failure. METHODS: Four databases were searched to identify studies investigating malaria antibody levels in patients receiving anti-malarial treatment for symptomatic malaria with treatment failure recorded according to the World Health Organization classification...

Acacia ligulata A.Cunn. ex Benth. (Fabaceae: Mimosoideae) is a native Australian plant used traditionally by Australian Aboriginal groups. This study was undertaken to investigate the bioactivity of A. ligulata extracts and to evaluate their chemical composition. Potential antibacterial, cytotoxic and enzyme inhibitory effects relevant to traditional medicinal and food uses of the species were examined and LC-MS/MS was performed to investigate the chemical composition. Antibacterial activity was observed for bark and leaf extracts with an MIC for the bark extract of 62...

Mutations in KAT6B gene are responsible for Say-Barber-Biesecker-Young-Simpson syndrome (SBBYSS) and genitopatellar syndrome (GPS), with most mutations occurring in exon 18. A 4-year-old Chinese boy presented with short stature but no other clinical features of SBBYSS or GPS had a de novo novel nonsense pathogenic mutation in exon 14 of the KAT6B gene at position c.2636T>A (p.Leu879X). The correlation analysis of genotype-phenotype indicated distinctive clinical features (short stature, growth hormone deficiency, and delayed bone age) compared with the classical mutations of KAT6B gene...

Sputum basophil numbers are increased in allergic asthmatics, but it is unclear what role airway basophils play in "TH2-low" asthma phenotypes. Using flow cytometry we found that basophils were significantly increased in all asthmatics (n=26) compared with healthy controls (n=8) (p=0.007) with highest levels observed in eosinophilic asthma (EA; median 0.22%, IQR 0.11-0.47%; n=14) compared with non-EA (0.06%, 0.00-0.20%; n=12; p<0.05). In asthmatics, basophils were positively correlated with sputum eosinophils (r=0...
