RATIONALE, AIMS, AND OBJECTIVES: A reduction in the provision of hospital services on the weekend probably explains higher mortality for patients who are either admitted to hospital or undergo procedures on the weekend. The aim was to examine the effect of the day of the week of admission (DOWOA) upon the efficiency and quality of care for a cohort of General Medical inpatients. METHODS: Electronic records were selected for unplanned adult admissions to 2 large public hospitals in Adelaide, South Australia, July 2012 to June 2017...

BACKGROUND: Complex interactions between environmental and genetic factors influence the risk for developing alcohol use disorder (AUD) in humans. To date, studies of the impact of environment on AUD risk have primarily focused on psychological characteristics or on the effects of developmental exposure to ethanol. We recently observed that modifying levels of the long-chain ω-3 (LC ω-3) fatty acid, eicosapentaenoic acid (EPA), alters acute physiological responses to ethanol in C. elegans...

Cancer studies have entered an era that is heavily focused on the contribution of the tumor microenvironment. For this reason, in vivo experimentation in an immunodeficient model system is no longer fit for purpose. As a consequence, numerous genetically engineered mouse models (GEMMs) which self-develop tumors have been developed to allow experiments to be performed in a fully immunocompetent setting. One of the most commonly used technologies is Cre-loxP recombination due to its unique ability to control target gene expression in a specified tissue type...

Pulmonary hypertension (PH) is a chronic progressive disease characterized by elevated pulmonary arterial pressure, caused by an increase in pulmonary arterial impedance. Computational fluid dynamics (CFD) can be used to identify metrics representative of the stage of PH disease. However, experimental validation of CFD models is often not pursued due to the geometric complexity of the model or uncertainties in the reproduction of the required flow conditions. The goal of this work is to validate experimentally a CFD model of a pulmonary artery phantom using a particle image velocimetry (PIV) technique...

BACKGROUND: Comorbidity constitutes a serious challenge for rehabilitative medicine. The comorbidity of the dorsopathy of the lumbar spine and irritable bowel syndrome mutually complicates the clinical course of both conditions, significantly reduces the patients' quality of life. and increases the costs of diagnostic procedures and restoration of the working capacity. The approaches to the non-pharmacological management of the patients presenting with these diseases remain to be developed...

Human pluripotent stem cells (PSCs) offer a scalable alternative to primary and transformed human tissue. PSCs include human embryonic stem cells, derived from the inner cell mass of blastocysts unsuitable for human implantation; and induced PSCs, generated by the reprogramming of somatic cells. Both cell types display the ability to self-renew and retain pluripotency, promising an unlimited supply of human somatic cells for biomedical application. A distinct advantage of using PSCs is the ability to select for genetic background, promising personalized modelling of human biology 'in a dish' or immune-matched cell-based therapies for the clinic...

There has been a recent resurgence in debate about methods for statistical inference in science. The debate addresses statistical concepts and their impact on the value and meaning of analyses' outcomes. In contrast, philosophical underpinnings of approaches and the extent to which analytical tools match philosophical goals of the scientific method have received less attention. This short piece considers application of the scientific method to "what-is-the-influence-of x-on-y" type questions characteristic of sport and exercise science...

Traumatic axonal injury (TAI) contributes significantly to mortality and morbidity after traumatic brain injury (TBI) but its identification is still a diagnostic challenge because of the limitations of conventional imaging techniques to characterized it. Diffusion tensor imaging (DTI) can indirectly identify areas of damaged white matter (WM) integrity by detecting water molecules diffusion alterations. Therefore, DTI may improve detection and description of TAI lesions after TBI. We have obtained DTI data from 217 patients with moderate to severe TBI acquired at median 19 days after TBI were and patient DTI metrics were compared with data obtained from 58 age-matched healthy controls...

PURPOSE: Retinol binding protein 4 (RBP4) has recently been identified as an adipokine possibly involved in the development of impaired glucose metabolism. We aimed to test serum RBP4 in healthy non-obese individuals and in patients with well-characterized phenotype: obesity without confounding effects of diabetes, metabolic syndrome or dyslipidemia. Additionally, we examined whether serum RBP4 is associated with anthropometric parameters, insulin resistance and blood lipid parameters...

One-carbon metabolism biomarkers are easily measured in plasma, but analyzing them one at a time in relation to disease does not take into account the interdependence of the many factors involved. The relative dynamics of major one-carbon metabolism branches can be assessed by relating the functional B-vitamin marker total homocysteine (tHcy) to transsulfuration (total cysteine) and methylation (creatinine) outputs. We validated the ratios of tHcy to total cysteine (Hcy:Cys), tHcy to creatinine (Hcy:Cre), and tHcy to cysteine to creatinine (Hcy:Cys:Cre) as functional markers of B-vitamin status...
