Introduction: Leptin is an adipokine which has a direct relationship to obesity. Our aim was to measure this hormone in pregnant women at three months intervals throughout their pregnancies to determine the serum value of those who developed preeclampsia.
Material And Methods: We followed 19 women (median age 24.8 +/- 5.7 years) with pre-gestational Body Mass Index (BMI) less than 25 kg/m2, 21 (median age 26.1 +/- 4.6 years) with BMI higher than 25 kg/m2 and 16 (median age 30.9 +/- 5.8 years) with Gestational Diabetes Mellitus (GDM) (median age 30.9 +/- 5.8 years), recruited in the 1st trimester of pregnancy. Serum levels of leptin were measured with radioimmunoassay (RIA) technique.
Results: In the first trimester of pregnancy leptin levels showed statistically significant differences between normal weight and overweight-obese women (p < 0.001), diabetic women (p < 0.05) and the subgroup of preeclamptic women (p < 0.001). For those women with PGBMI > or = 40 kg/m2 and leptin > or = 40 ng/ml in the second trimester, the Odds Ratio (OR) to develop preeclampsia was of 47.95% CI (4.1-527.2). Analyzing leptin values with ROC curves, the greatest area under the curve (AUC) was for leptin in the second trimester (0.773, CI: 0.634-0.911).
Conclusion: Women with morbid obesity (BMI > or = 40 kg/m2) had significantly higher levels of serum leptin (p < 0.01) and a value of 40 ng/ml of this hormone seems to be predictive of developing preeclampsia in this group of patients.

Importance: Using albumin-adjusted calcium is commonly recommended for for measuring calcium, but with little empirical evidence to support the practice.
Objective: To assess the correlation between total calcium measurements (with or without adjustment) vs the ionized calcium level as a reference standard.
Design, Setting, And Participants: This was a population-based cross-sectional study in the province of Alberta, Canada, including adults tested for serum total calcium and ionized calcium simultaneously between January 1, 2013, and October 31, 2019.

Importance: Disease characteristics of genetically mediated coronary artery disease (CAD) on coronary angiography and the association of genomic risk with outcomes after coronary angiography are not well understood.
Objective: To assess the angiographic characteristics and risk of post-coronary angiography outcomes of patients with genomic drivers of CAD: familial hypercholesterolemia (FH), high polygenic risk score (PRS), and clonal hematopoiesis of indeterminate potential (CHIP).
Design, Setting, And Participants: A retrospective cohort study of 3518 Mass General Brigham Biobank participants with genomic information who underwent coronary angiography was conducted between July 18, 2000, and August 1, 2023.

Importance: Secondary lymphedema is a common, harmful side effect of breast cancer treatment. Robust risk models that are externally validated are needed to facilitate clinical translation. A published risk model used 5 accessible clinical factors to predict the development of breast cancer-related lymphedema; this model included a patient's mammographic breast density as a novel predictive factor.

Importance: There is limited evidence regarding the association between age at menopause and incident type 2 diabetes (T2D).
Objective: To investigate whether age at menopause and premature menopause are associated with T2D incidence in postmenopausal Korean women.
Design, Setting, And Participants: This population-based cohort study was conducted among a nationally representative sample from the Korean National Health Insurance Service database of 1 125 378 postmenopausal women without T2D who enrolled in 2009.

Background: Japanese encephalitis virus (JEV) is a leading cause of viral encephalitis in Asia, with high case-fatality rate and morbidity. Although the live recombinant Japanese encephalitis chimeric vaccine (Imojev®) offers strong initial immunity, data on long-term efficacy beyond five years remain limited.
Methods: We conducted a cross-sectional study on adults vaccinated with Imojev® at a specialist travel clinic in Brisbane, Australia.
