Article Synopsis
  • Clinical trials, essential for healthcare, also significantly contribute to climate change; researchers have developed a method to calculate their carbon footprint and applied it to 10 UK and international trials.
  • Data on trial activities was collected from 10 trial units, evaluated for emission sources, and feedback was gathered on the carbon footprint calculation process.
  • The carbon footprints of the trials varied widely, highlighting key areas for emissions reduction, with suggestions to incorporate carbon footprint considerations during the trial design phase.

Aims/hypothesis: Gestational diabetes mellitus (GDM) is associated with adverse perinatal outcomes because of suboptimal glucose management and glucose control and excessive weight gain. Metformin can offset these factors but is associated with small for gestational age (SGA) infants. We sought to identify risk factors for SGA infants, including the effect of metformin exposure on SGA status.

Metformin is a commonly used drug in the treatment of type 2 diabetes and has been used to treat gestational diabetes since the 1970s. In pregnancy, its proven benefits include reduced gestational weight gain and reduced fetal size; some studies have shown reduced risk of cesarean delivery and lower rates of hypertension. Metformin can reduce the need for insulin therapy but does not eliminate such need in many patients.

Aims: To undertake a Priority Setting Partnership (PSP), identifying the most important unanswered questions in type 1 diabetes in Ireland and the United Kingdom and to compare these to priorities identified in a 2011 PSP.

Methods: A steering committee (including eight individuals with lived experience/charity representatives and six clinicians) designed a survey which asked stakeholders to list three questions about type 1 diabetes. This was disseminated through social media, direct email contact, and printed posters.

Aim: Women with GDM display adverse lifetime cardio-metabolic health. We examined whether early metformin in GDM could impact cardio-metabolic risk factors postpartum.

Research Design & Methods: EMERGE, a double-blind, placebo-controlled trial randomized pregnancies 1:1 to placebo or metformin at GDM diagnosis and followed participants from randomization until 12±4 weeks postpartum.

Background: Although aspirin therapy is being increasingly advocated with the intention of risk modification for a wide range of pregnancy complications, women with prepregnancy diabetes mellitus are commonly excluded from clinical trials.

Objective: The primary aim of this study was to examine the effect of aspirin therapy on a composite measure of adverse perinatal outcome in pregnancies complicated by pregestational diabetes mellitus.

Study Design: A double-blinded, placebo-controlled randomized trial was conducted at 6 university-affiliated perinatology centers.

Context: It is not clear if the risk of abnormal glucose tolerance (AGT) is attenuated in the long-term in women diagnosed with gestational diabetes (GDM) using the World Health Organization (WHO) 2013 criteria and who have received appropriate treatment during pregnancy.

Objective: We aimed to assess the long-term prevalence of AGT and other cardiovascular disease (CVD) risk factors in this cohort.

Methods: A retrospective cohort follow-up study was conducted of 37 and 107 women diagnosed with and without GDM respectively using the WHO 2013 criteria between June 2010 and December 2010.

Importance: Gestational diabetes is a common complication of pregnancy and the optimal management is uncertain.

Objective: To test whether early initiation of metformin reduces insulin initiation or improves fasting hyperglycemia at gestation weeks 32 or 38.

Design, Setting, And Participants: Double-blind, placebo-controlled trial conducted in 2 centers in Ireland (one tertiary hospital and one smaller regional hospital).

Metformin is used worldwide in the treatment of type 2 diabetes and has been used in the treatment of diabetes in pregnancy since the 1970s. It is highly acceptable to patients due to its ease of administration, cost and adverse effect profile. It is effective in reducing macrosomia, large-for-gestational-age infants and reduces maternal weight gain.

Objective: Primary hyperparathyroidism is a common endocrine disorder, with 80% of all cases usually caused by one single hyperfunctioning parathyroid adenoma. Conventional imaging modalities for the diagnostic work-up of primary hyperparathyroidism (PHPT) include ultrasound of the neck, 99mTc-sestamibi scintigraphy, and four-dimensional computed tomography (4D-CT). However, the role of other imaging modalities, such as 11C-methionine PET/CT, in the care pathway for PHPT is currently unclear.

Introduction: Pregestational diabetes (PGDM) is an increasingly common and complex condition that infers risk to both mother and infant. To prevent serious morbidity, strict glycaemic control is essential. The aim of this review is to review the glucose sensing and insulin delivering technologies currently available for women with PGDM.

Introduction: Type 1 diabetes mellitus occurs in one in every 275 pregnancies and can result in increased morbidity and mortality for both mother and baby. Several pregnancy complications can be reduced or prevented by attendance at pre-pregnancy care (PPC). Despite this, less than 40% of pregnant women with pre-gestational diabetes receive formal PPC.

Background Maternal opioid exposure during pregnancy has various effects on neonatal health. Buprenorphine/naloxone and methadone are examples of medications for opioid use disorder (MOUD) used for the treatment of opioid use disorder (OUD). Research comparing the impacts of these MOUD modalities on neonatal outcomes when used to treat pregnant people with OUD remains limited.

Aim: Report the outcomes of pregnant women with type 1 and type 2 diabetes and to identify modifiable and non-modifiable factors associated with poor outcomes.

Methods: Retrospective analysis of pregnancy preparedness, pregnancy care and outcomes in the Republic of Ireland from 2015 to 2020 and subsequent multivariate analysis.

Results: In total 1104 pregnancies were included.

Introduction: Diabetes mellitus is the most common metabolic complication of pregnancy and its prevalence worldwide is rising. The number of randomised controlled trials (RCTs) being conducted in people with diabetes is also increasing. Many studies preferentially publish findings on clinical endpoints and do not report patient-reported outcomes (PROs).

Cushing's syndrome is a rare disorder of cortisol excess and is associated with significant morbidity and mortality. Hypercalcaemia due to hyperparathyroidism is a common condition; however, in 10% of young patients, it is associated with other endocrinopathies and occurs due to a genetic variant [e.g.

Background: Immune checkpoint inhibitors (ICIs) are a novel class of oncological agents which are used to treat a number of malignancies. To date seven agents have been approved by the Food and Drug Administration (FDA) to treat both solid and haematological malignancies. Despite their efficacy they have been associated with a number of endocrinopathies.

Background: Klinefelter syndrome (KS) is the most common sex-chromosomal disorder in males. Frequently under-recognized, it occurs in 1 in 500-600 male births. It is caused by the inheritance of at least one additional X chromosome from either parent.

This qualitative study explored the experiences of social workers, nurses, and physicians providing end-of-life care to children in a pediatric acute-care hospital setting. Findings demonstrated that participants experienced both professional and personal impacts of their work and employed various coping strategies under each of these domains. The acute-care setting was found to create unique challenges in providing end-of-life care.

Issue Addressed: Smoking rates are high among Arabic-speaking populations, particularly men, and there is limited evidence to formulate effective tobacco-control strategies in this group. This study explored smoking within an Arabic-speaking community in Sydney, focusing on men's smoking in the context of their families.

Methods: We conducted six focus groups with a total of 60 Arabic-speaking participants recruited through health workers, counsellors and community leaders in Western Sydney, Australia.

Background And Objective: Forgoing artificial nutrition and hydration (FANH) in children at the end of life (EOL) is a medically, legally, and ethically acceptable practice under specific circumstances. However, most of the evidence on FANH involves dying adults. There is a paucity of pediatric evidence to guide health care providers' and parents' decision-making around this practice.
