This work reports experimental Ge(d,n)As cross sections producing Arsenic-71 (t = 65.3 h, 28% β), a potentially useful diagnostic radionuclide. Target stacks containing two Ge foils, a Ni monitor foil, and an Al degrader were irradiated with 5.5-10 MeV deuterons using an FN Tandem Van de Graaff accelerator. As and Cu, Co, and Co (from Ni(d,x)) were quantified in the foils by high purity germanium gamma spectrometry. The measured cross sections are larger than previously reported and suitable for producing preclinical quantities of diagnostic radiopharmaceuticals.

Regular human insulins versus rapid-acting insulin analogues in children and adolescents with type 1 diabetes: a protocol for a systematic review with meta-analysis and Trial Sequential Analysis.

Background: Type 1 diabetes is a serious, chronic disorder with an increasing incidence among children and adolescents. Glycemic control in individuals with type 1 diabetes is better managed through a basal-bolus regimen with either regular human or rapid-acting insulin analogues administered as a bolus at mealtimes. Rapid-acting insulin analogues have been hypothesized to cause optimal glycemic control and less risk of hypoglycemic episodes compared to regular human insulins.

Aim: To explore the holistic impact of socioeconomic and mental health inequalities on the global burden of type 2 diabetes.
Materials And Methods: This cross-sectional study used data on the incidence, disability-adjusted life years (DALYs), and mortality of type 2 diabetes as well as DALYs attributable to risk factors during 1990-2021 from the Global Burden of Disease Study 2021. Average annual percent change (AAPC) was applied to assess the temporal trends from 1990 to 2021.
Efficacy of Radiofrequency Ablation as a Treatment for High-Risk Gastric Intestinal Metaplasia: A Randomized, Self-Control Study.

Background: Guidelines recommend endoscopic surveillance for gastric cancer without therapeutic intervention every 3 years in patients with high-risk gastric intestinal metaplasia (GIM). This study aimed to evaluate the efficacy of radiofrequency ablation (RFA) in eradicating high-risk GIM.
Methods: This randomized self-control trial was conducted between June 2020 and February 2023.

Background: Subclinical depressive symptoms increase the risk of developing Alzheimer's disease (AD). The neurobiological mechanisms underlying this link may involve stress system dysfunction, notably related to the hippocampus which is particularly sensitive to AD. We aimed to investigate the links between blood stress markers and changes in brain regions involved in the stress response in older adults with or without subclinical depressive symptoms.

Background: The life expectancy of people living with human immunodeficiency virus (PLWH) has significantly improved with advancements in antiretroviral therapy (ART). However, aging PLWH face a growing burden of non-communicable diseases (NCDs), polypharmacy, and drug-drug interactions (DDIs), which pose challenges in their management. This study investigates the prevalence of NCDs, polypharmacy, and DDIs among PLWH aged ≥50 years in Korea and their impact on quality of life (QOL).
