Sex-mediated effects of transglutaminase 2 inhibition on endothelial function in human resistance arteries from diabetic and non-diabetic patients.

Transglutaminase 2 (TG2) is an enzyme with multiple conformations. In its open conformation, TG2 exhibits transamidase activity linked to fibrosis, arterial remodeling, and endothelial dysfunction, a process enhanced by high glucose in endothelial cells. However, the closed conformation of TG2 contributes to transmembrane signaling and nitric oxide (NO)-dependent vasorelaxation.

SGLT2 inhibition improves endothelium-independent vasodilatory function in type 2 diabetes: A double-blind, randomized, placebo-controlled crossover trial.

Aims: The objective of this study was to examine the effects of empagliflozin on endothelium-dependent and endothelium-independent vasodilatation and systemic hemodynamic parameters and to assess the role of the nitric oxide (NO) system in patients with type 2 diabetes (T2DM).

Materials And Methods: In this double-blind, placebo-controlled cross over trial, patients with T2DM were treated with either empagliflozin 10 mg or matching placebo for 4 weeks. Following a 2-week washout, participants were crossed over to 4 weeks of the opposite treatment.

PIVKA-II but not dp-ucMGP is associated with aortic calcification in chronic kidney disease.

Background: Patients with chronic kidney disease (CKD) are susceptible to vascular calcification and vitamin K deficiency. Matrix gla protein (MGP) is a potent inhibitor of calcification requiring vitamin K for activation. Inactive MGP, i.

A Urine pH-Ammonium Acid/Base Score and CKD Progression.

Key Points: This study developed a urine acid/base score to assess tubular acid excretion capacity and identify early acid retention in CKD. The results show that early signs of acid retention (a low acid/base score) are associated with a higher risk for CKD progression. Future research should address if a low urine acid/base score can be improved and if this translates into clinically meaningful effects.

Banging My Head Against a Brick Wall! Enablers and Barriers to Nurse Practitioners Delivering Opioid Agonist Treatments in Regional/Rural Victoria, Australia.

The Victorian government's Alcohol and other drugs (AOD) workforce policy calls for greater recruitment of alcohol and other drugs nurse practitioners (AODNPs). However, frontline organisations in Victoria report several systemic barriers to their recruitment and retention. Additionally, there is scant Australian literature that examines the experiences of AODNP in opioid agonist treatment (OAT) provision in regional/rural areas.

Characteristics of Clinical Supervision for Mental Health Nurses: A Survey Study Using the MCSS-26.

Aim(s): To describe the characteristics and perceived effectiveness of clinical supervision mental health nurses are receiving and further explore any statistical correlations between the perceived effectiveness and satisfaction with the supervisee, supervisor and supervision characteristics.

Design: A cross-sectional survey.

Methods: An online survey was distributed to nurses working in public mental health services in Victoria, Australia.

Pharmacological modulation of transglutaminase 2 in the unilateral ureteral obstruction mouse model.

Background: Transglutaminase 2 (TG2) is a multifunctional enzyme involved in fibrosis by promoting transforming-growth-factor-β1 and crosslinking of extracellular matrix proteins. These functions are dependent on the open conformation, while the closed state of TG2 can induce vasodilation. We explored the putative protective role of TG2 in its closed state on development of renal fibrosis and blood pressure (BP) regulation.

Ex Vivo Simultaneous HO Positron Emission Tomography and Magnetic Resonance Imaging of Porcine Kidneys-A Feasibility Study.

Unlabelled: The aim was to establish combined HO PET/MRI during ex vivo normothermic machine perfusion (NMP) of isolated porcine kidneys. We examined whether changes in renal arterial blood flow (RABF) are accompanied by changes of a similar magnitude in renal blood perfusion (RBP) as well as the relation between RBP and renal parenchymal oxygenation (RPO).

Methods: Pig kidneys (n = 7) were connected to a NMP circuit.

Factors that influence the clinical supervision implementation for nurses: A scoping review.

Aims: The aim of this review is to identify and map the evidence available on the factors that influence the implementation of clinical supervision for nurses.

Design: The scoping review was conducted and reported following the JBI methodology for scoping reviews.

Data Sources: Searches were conducted on MEDLINE, PsycINFO, and CINAHL databases on 28 March 2023.

Geographical Differences in Hydrochlorothiazide Associated Risk of Skin Cancer Balanced Against Disability Related to Hypertensive Heart Disease.

Background: Hypertension affects 25%-30% of the world population. Hydrochlorothiazide (HCTZ) is among the most used and cheapest medications but was in 2018 labeled with a warning stating the increased risk of nonmelanoma skin cancer (NMSC). This study describes geographical differences in the association between HCTZ and NMSC from the perspective of hypertensive heart disease (HHD).

Evidence for routine brain-to-pelvis imaging and antiplatelet therapy in patients diagnosed with fibromuscular dysplasia.

Fibromuscular dysplasia (FMD) is a disease of the musculature of arterial walls leading to stenoses, aneurysms, and dissections. The purpose of this report was to summarize the evidence for (1) one-time routine imaging from brain-to-pelvis and (2) lifelong antiplatelet therapy, for example, aspirin, for patients diagnosed with FMD as suggested by an international consensus report from 2019. PubMed was systematically searched, and the evidence providing a basis for the current consensus points, as well as articles published since, were reviewed.

The impact of early intervention psychosis services on hospitalisation experiences: a qualitative study with young people and their carers.

Background: While a core aim of early intervention psychosis services (EIPS) is to prevent hospitalisation, many with a first episode of psychosis (FEP) will require inpatient care. We explored young people's (YP) and their carers' hospitalisation experiences prior to and during EIPS engagement and how factors across these services influenced these experiences.

Methods: Using purposive sampling, we recruited twenty-seven YP, all of whom had been involved with the hospital system at some stage, and twelve support persons (parents and partners of YP) from state and federally funded EIPS in Australia with different models of care and integration with secondary mental health care.

Effects of Empagliflozin in Type 2 Diabetes With and Without Chronic Kidney Disease and Nondiabetic Chronic Kidney Disease: Protocol for 3 Crossover Randomized Controlled Trials (SiRENA Project).

Background: Sodium-glucose-cotransporter 2 inhibitors (SGLT2is) have revolutionized the treatment of type 2 diabetes mellitus (DM2) and chronic kidney disease (CKD), reducing the risk of cardiovascular and renal end points by up to 40%. The underlying mechanisms are not fully understood.

Objective: The study aims to examine the effects of empagliflozin versus placebo on renal hemodynamics, sodium balance, vascular function, and markers of the innate immune system in patients with DM2, DM2 and CKD, and nondiabetic CKD.

Power, position and social relations: Is the espoused absence of hierarchy in Open Dialogue naïve?

Open Dialogue practitioners aim to reduce social hierarchies by not privileging any one voice in social network conversations, and thus creating space for a polyphony of voices. This sits in contrast to the traditional privileging of those voices credited with more knowledge or power because of social position or professional expertise. Using qualitative interviews, the aim of this current study was to explore Open Dialogue practitioners' descriptions of challenges in implementing Open Dialogue at a women's health clinic in Australia.

Co-designing formal health professions curriculum in partnership with students: A scoping review.

There is growing evidence of the value of co-design and partnering with students in the design, development, and delivery of health professions education (HPE). However, the way in which students participate in co-designing HPE remains largely unexplored and there is little guidance on how to embed and strengthen partnerships with students. Using scoping review methodology, we identified and aggregated research reporting studies in which students were active partners in co-designing formal curricula in HPE.

Aortic Calcification is Associated With the Difference Between Invasive Central and Cuff-Measured Brachial Blood Pressure in Chronic Kidney Disease.

Background: Chronic kidney disease (CKD) is associated with accelerated vascular calcification and increased central systolic blood pressure when measured invasively (invCSBP) relative to cuff-based brachial systolic blood pressure (cuffSBP). The contribution of aortic wall calcification to this phenomenon has not been clarified. We, therefore, examined the effects of aortic calcification on cuffSBP and invCSBP in a cohort of patients representing all stages of CKD.

Invasively Measured Aortic Systolic Blood Pressure and Office Systolic Blood Pressure in Cardiovascular Risk Assessment in CKD.

Introduction: Central aortic blood pressure (BP) could be a better risk predictor than brachial BP. This study examined whether invasively measured aortic systolic BP improved outcome prediction beyond risk prediction by conventional cuff-based office systolic BP in patients with and without chronic kidney disease (CKD).

Methods: In a prospective, longitudinal cohort study, aortic and office systolic BPs were registered in patients undergoing elective coronary angiography (CAG).

Assisting refugee survivors of torture and trauma: An existential perspective.

Consistent exposure to refugee narratives of trauma and torture can profoundly impact trauma therapists. This secondary analysis reanalyzed data from a narrative inquiry investigating the lived experiences of refugee trauma therapists. We aimed to explore emergent concerns through an existential lens to enrich understanding and provide additional insights into the lived experiences of these individuals.

Absence of Coronary Artery Disease is a Strong Negative Predictor of Major Adverse Cardiovascular Events in Patients with Chronic Kidney Disease.

Purpose: To investigate the interplay between chronic kidney disease (CKD) and coronary artery disease (CAD) on the incidence of cardiovascular events in patients with suspected chronic coronary syndrome (CCS).

Patients And Methods: Patients with suspected CCS who underwent first-time coronary angiography in Western Denmark between 2003 and 2016 were included in this cohort study. Moreover, an age- and sex-matched general population cohort was established.

What does consumer and community involvement in health-related education look like? A mixed methods study.

Consumer and community involvement (also referred to as patient and public involvement) in health-related curricula involves actively partnering with people with lived experience of health and social care systems. While health professions education has a long history of interaction with patients or consumers, a shift in the way consumer and community engage in health-related education has created novel opportunities for mutual relationships valuing lived experience expertise and shifting traditional education power relations. Drawing on a mixed methods design, we explored consumer and community involvement practices in the design and delivery of health-related education using the capability, opportunity, motivation and behaviour framework (COM-B).

Sense of psychological ownership in co-design processes: A case study.

Introduction: Service users are increasingly participating in health research. Although collaborative research is assumed to give users a sense of psychological ownership, little is known about the specific psychosocial processes through which ownership develops and is displayed. The present study yields insight into a process in which service users, researchers and a website designer collaborated to design a website.
