Haemodynamic, hormonal and renal actions of osteocrin in normal sheep.

Osteocrin (OSTN) is an endogenous protein sharing structural similarities with the natriuretic peptides [NPs; atrial (ANP), B-type (BNP) and C-type (CNP) NP], which are hormones known for their crucial role in maintaining pressure/volume homeostasis. Osteocrin competes with the NPs for binding to the receptor involved in their clearance (NPR-C). In the present study, having identified, for the first time, the major circulating form of OSTN in human and ovine plasma, we examined the integrated haemodynamic, endocrine and renal effects of vehicle-controlled incremental infusions of ovine proOSTN (83-133) and its metabolism in eight conscious normal sheep.

Comparing automated cell imaging with conventional methods of measuring cell proliferation and viability.

The ability to assess cell proliferation and viability is essential for assessing new drug treatments, particularly in cancer drug discovery. This study describes a new method that uses a plate reader digital microscopy cell imaging and analysis system to assess cell proliferation and viability. This imaging system utilizes high throughput fluorescence microscopy with two fluorescent probes: cell membrane-impermeable SYTOX green and nuclear binding Hoechst-33342.

Protocol for Improving Care by FAster risk-STratification through use of high sensitivity point-of-care troponin in patients presenting with possible acute coronary syndrome in the EmeRgency department (ICare-FASTER): a stepped-wedge cluster randomised quality improvement initiative.

Introduction: Clinical assessment in emergency departments (EDs) for possible acute myocardial infarction (AMI) requires at least one cardiac troponin (cTn) blood test. The turn-around time from blood draw to posting results in the clinical portal for central laboratory analysers is ~1-2 hours. New generation, high-sensitivity, point-of-care cardiac troponin I (POC-cTnI) assays use whole blood on a bedside (or near bedside) analyser that provides a rapid (8 min) result.

An evaluation of psychosocial sleep interventions for children with chronic health conditions: A systematic review.

Chronic health conditions (CHC; e.g., cystic fibrosis, type 1 diabetes) in children are associated with disease-specific physical symptoms that contribute to a high prevalence of sleep problems.

Blood Vitamin C Levels of Patients Receiving Immunotherapy and Relationship to Monocyte Subtype and Epigenetic Modification.

The treatment of metastatic melanoma has been revolutionised by immunotherapy, yet a significant number of patients do not respond, and many experience autoimmune adverse events. Associations have been reported between patient outcome and monocyte subsets, whereas vitamin C (ascorbate) has been shown to mediate changes in cancer-stimulated monocytes in vitro. We therefore investigated the relationship of ascorbate with monocyte subsets and epigenetic modifications in patients with metastatic melanoma receiving immunotherapy.

Level of and factors associated with foot self-care among people with diabetes in Idlib Province of Northwest Syria: A cross-sectional study.

Background And Aims: Diabetic foot and lower limb problems are among the most neglected complications during the Syrian armed conflict due to the absence of a functioning health infrastructure, including early detection and timely management of limb-threatening wounds. This study aimed to determine self-reported diabetes-related foot disease (DRFD), adherence to recommended foot self-care (FSC) practices, and associated factors among people with diabetes in war-torn Northwest Syria (NWS).

Methods: This was a cross-sectional study conducted at six primary care clinics in Idlib, NWS, between March 27 and April 17, 2022, utilizing the validated interviewer-administered Diabetes Foot Disease and Foot Care Questionnaire.

Isolated Traumatic Membranous Interventricular Septal Rupture: A Rare Complication Following a Motor Vehicle Accident.

• Isolated VSRs are rare after blunt force trauma. • Traumatic VSRs more commonly occur within the apex. • Early diagnosis with echocardiography is imperative for optimal management of VSRs.

Neurodevelopmental Outcomes Following Childhood Viral Meningitis in Canterbury New Zealand.

Background: Most childhood meningitis is viral in countries with widespread conjugate vaccine use. This study assessed clinical features and neurodevelopmental outcomes in preschool children following enteroviral and parechoviral meningitis.

Methods: Children 18-42 months of age in Canterbury, New Zealand were included, who had enterovirus (EV) or parechovirus (HPEV) meningitis from 2015 to 2021.

Determination of Clinically Acceptable Analytical Variation of Cardiac Troponin at Decision Thresholds.

Background: Clinical decision-making for risk stratification for possible myocardial infarction (MI) uses high-sensitivity cardiac troponin (hs-cTn) thresholds that range from the limit of detection to several-fold higher than the upper reference limit (URL). To establish a minimum analytical variation standard, we can quantify the effect of variation on the population clinical measures of safety (sensitivity) and effectiveness [proportion below threshold, or positive predictive value (PPV)].

Methods: From large datasets of patients investigated for possible MI with the Abbott hs-cTnI and Roche hs-cTnT assays, we synthesized datasets of 1 000 000 simulated patients.

Australian and New Zealand Living Guideline cholesterol-lowering therapy for people with chronic kidney disease (CARI Guidelines): Reducing the evidence-practice gap.

Aim: People with chronic kidney disease experience high rates of cardiovascular disease. Cholesterol-lowering therapy is a mainstay in the management but there is uncertainty in the treatment effects on patient-important outcomes, such as fatigue and rhabdomyolysis. Here, we summarise the updated CARI Australian and New Zealand Living Guidelines on cholesterol-lowering therapy in chronic kidney disease.

Angiotensin-converting-enzyme inhibitors and angiotensin receptor blockers for preventing the progression of diabetic kidney disease.

Background: Guidelines suggest that adults with diabetes and kidney disease receive treatment with angiotensin-converting-enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARB). This is an update of a Cochrane review published in 2006.

Objectives: We compared the efficacy and safety of ACEi and ARB therapy (either as monotherapy or in combination) on cardiovascular and kidney outcomes in adults with diabetes and kidney disease.

Effects of Resveratrol on In Vivo Ovarian Cancer Cells Implanted on the Chorioallantoic Membrane (CAM) of a Chicken Embryo Model.

Ovarian cancer poses a significant threat to patients in its advanced stages, often with limited treatment options available. In such cases, palliative management becomes the primary approach to maintaining a reasonable quality of life. Therefore, the administration of any medication that can benefit patients without a curative option holds potential.

Changes in urinary glutathione sulfonamide (GSA) levels between admission and discharge of patients with cystic fibrosis.

There is an urgent need to develop sensitive, non-invasive biomarkers that can track airway inflammatory activity for patients with cystic fibrosis (CF). Urinary glutathione sulfonamide (GSA) levels correlate well with GSA levels in BAL samples and other markers of neutrophilic inflammation, suggesting that this biomarker may be suitable for tracking disease activity in this population. We recruited 102 children (median 11.

Urinary Proteomics and Outcomes in Heart Failure With Preserved Ejection Fraction.

Background: Although several studies have addressed plasma proteomics in heart failure with preserved ejection fraction, limited data are available on the prognostic value of urinary proteomics. The objective of our study was to identify urinary proteins/peptides associated with death and heart failure admission in patients with heart failure with preserved ejection fraction.

Methods And Results: The study population included participants enrolled in TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist Trial).

Do treatment patterns differ in those with early-onset colorectal cancer?

Background: The incidence of early-onset colorectal cancer (EOCRC) is increasing. International guidelines state that treatment should not differ from that of older patients. Several studies have shown that patients under 50 years are receiving more aggressive treatment, without any survival benefit.
