Background: Despite evidence supporting interventions that improve outcomes for patients with stroke, their implementation remains suboptimal. Facilitation can support implementation of research into clinical practice by helping people develop the strategies to implement change. However, variability in the amount (dose) and type of facilitation activities/facilitator roles that make up the facilitation strategies (content), may affect the effectiveness of facilitation.

Gestational diabetes (GDM) is associated with a long-term risk of diabetes. We aimed to determine whether a text-messaging-based lifestyle support program would improve diabetes risk factors following GDM. Women with GDM were randomised following delivery to receive four text messages per week supporting a healthy lifestyle and parenting for 6 months, with feedback from an activity monitor (intervention), or to receive the activity monitor only (control).

Maintenance of quiescence and DNA replication dynamics are 2 paradoxical requirements for the distinct states of dormant and active hematopoietic stem cells (HSCs), which are required to preserve the stem cell reservoir and replenish the blood cell system in response to hematopoietic stress, respectively. Here, we show that key self-renewal factors, β-catenin or Hoxa9, largely dispensable for HSC integrity, in fact, have dual functions in maintaining quiescence and enabling efficient DNA replication fork dynamics to preserve the functionality of hematopoietic stem and progenitor cells (HSPCs). Although β-catenin or Hoxa9 single knockout (KO) exhibited mostly normal hematopoiesis, their coinactivation led to severe hematopoietic defects stemmed from aberrant cell cycle, DNA replication, and damage in HSPCs.

Introduction: The aim of this study was to determine the prevalence of diabetic retinopathy (DR) in a low socioeconomic region of a high-income country, as well as determine the diagnostic utility of point-of-care screening for high-risk populations in tertiary care settings.

Research Design And Methods: This was a cross-sectional study of patients with diabetes attending foot ulcer or integrated care diabetes clinics at two Western Sydney hospitals (n=273). DR was assessed using portable, two-field, non-mydriatic fundus photography and combined electroretinogram/ pupillometry (ERG).

Background: The Electronic Health Record Sharing System (eHRSS) is an electronic platform for two-way communication between the public and private sectors in Hong Kong. The authorised healthcare professionals (HCProfs) could access and upload patients' health records on the eHR Viewer in the eHRSS. This study aims to evaluate the usage of eHR viewer among the HCProfs from the private sector by 1) examining the correlation of various factors and the data access of eHR viewer; 2) investigating the trend on data access and upload to eHR viewer by time period and domain.

In January 2021, the eHealth App was launched in Hong Kong by the Hong Kong government to support the Electronic Health Record Sharing System (eHRSS). A Health Management Module in the eHealth App introduced new functions to record blood pressure, blood sugar, and heart rate, and downloading and sharing records. This study aims to compare the level of glycaemic control between users of the eHealth App and non-users.

Article Synopsis
  • - Poor adherence to stroke care guidelines is a global issue, but the QASC trial showed that nurse-led implementation can significantly improve patient outcomes like death and disability.
  • - A multi-country study from 2017 to 2021 assessed the effectiveness of the FeSS Protocol across 64 hospitals, revealing substantial improvements in the care elements related to fever, hyperglycemia, and swallowing.
  • - The successful rollout of the FeSS Protocol across diverse healthcare systems demonstrated that both high-income and middle-income countries could achieve similar enhancements in stroke care practices.

Background: In the second stage of the Electronic Health Record Sharing System (eHRSS) development, a mobile app (eHealth app) was launched to further enhance collaborative care among the public sector, the private sector, the community, and the caregivers.

Objective: This study aims to investigate the factors associated with the downloading and utilization of the app, as well as the awareness, perception, and future improvement of the app.

Methods: We collected 2110 surveys; respondents were stratified into 3 groups according to their status of enrollment in the eHRSS.

Aims: To determine the prevalence of metabolic dysfunction-associated fatty liver disease (MAFLD) and its association on adverse pregnancy outcomes in women with gestational diabetes mellitus (GDM).

Methods: 380 women with GDM had a FibroScan® performed between 24 and 32 weeks. A Controlled Attenuation Parameter (CAP) ≥ 233.

Background: Metabolic-associated fatty liver disease (MAFLD) is a leading cause of chronic liver disease with increasingly recognised associations with gestational diabetes (GDM), including within the antenatal period.

Aims: To assess the relationship between MAFLD in pregnancy and development of GDM.

Methods: Fifty pregnant women were enrolled before 24 weeks gestation from a multiethnic obstetrics service in Sydney, Australia.

Background: A tele-rehabilitation platform was developed to improve access to ambulatory rehabilitation services in Hong Kong. The development was completed in October 2019 and rolled out for use to occupational therapists, physiotherapists, and speech therapists. During the COVID-19 pandemic, rehabilitation services were severely interrupted.

Aims: To further explore the relationship between non-alcoholic fatty liver disease (NAFLD) and gestational diabetes mellitus (GDM) by determining the prevalence of GDM in women diagnosed with NAFLD antepartum.

Methods: Electronic databases were searched using specific keywords. Original studies of adult women reporting NAFLD (confirmed on imaging) and GDM (confirmed via oral glucose tolerance test) prevalence were included.

Perioperative ketoacidosis is an important adverse event related to the use of sodium glucose co-transporter 2 inhibitor (SGLT2i). We compared perioperative outcomes in patients on SGLT2i, before and after protocolised pre-operative cessation of the drug. There were no cases of clinically detected diabetic ketoacidosis in the 96 patients included in the study.

Article Synopsis
  • A study was conducted to assess how well pregnancy care for women with high blood sugar levels is benchmarked across diabetes services in Australia and New Zealand, focusing on data from 2014 to 2020.
  • The audit analyzed 10,144 pregnancies and found significant variations in treatment methods (like diet vs. medication) and outcomes (like cesarean rates and preterm births) across different centers.
  • The findings suggest that there is potential to enhance the care and outcomes for pregnant women with hyperglycemia by using benchmarking to identify effective policies and clinical practices.

Background: Many countries adopt eHealth applications to support patient-centered care. Through information exchange, these eHealth applications may overcome institutional data silos and support holistic and ubiquitous (regional or national) information logistics. Available eHealth indicators mostly describe usage and acceptance of eHealth in a country.

The balance between avoiding severe acute respiratory syndrome coronavirus-2 contagion and reducing wider clinical risk is unclear for gestational diabetes mellitus (GDM) testing. Recent recommendations promote diagnostic approaches that limit collection but increase undiagnosed GDM, which potentially increases adverse pregnancy outcome risks. The most sensitive approach to detecting GDM at 24-28 weeks beyond the two-hour oral glucose tolerance test (OGTT) is a one-hour OGTT (88% sensitivity).

Introduction: Low-cost interventions providing self-management support are needed for people with coronary artery disease (CAD) and diabetes. Mobile phone text messaging provides a potential vehicle for this. The SupportMe Trial aims to assess the feasibility of embedding a text messaging programme into routine clinical practice and will determine if this improves cardiovascular risk factor and diabetes control among patients with CAD or type 2 diabetes.
