Objective: to analyze the spatial-temporal pattern of childbirths and flow of postpartum women assisted at a regional reference maternity hospital.

Methods: ecological study of 4,081 childbirths, between September 2018 and December 2021, at a public maternity hospital in the Baixo Tocantins region, Pará, Brazil. With data collected from five sources, a geographic database was constructed, and spatial analysis was used with Kernel density interpolator.

Background: Prostate cancer therapy with surgical or chemical castration with GnRH agonists has been linked to elevated FSH levels, which may contribute to secondary health disorders, including atherosclerosis and diabetes. Although recent findings suggest a role for FSH beyond the reproductive system, its metabolic impact remains unclear and difficult to disentangle from that of androgens. In this study, we examined the metabolic changes induced by FSH and distinguished them from those caused by testosterone.

Introduction: In diabetics, glucagon-like peptide 1 (GLP-1) receptor agonists (RA) may protect against microvascular alterations and oxidative stress, both of which have been implicated in glaucoma. Multiple studies suggest a possible relation between GLP-1 RA use and the development of glaucoma. This study performs a systematic review of the literature regarding the incidence of glaucoma development in type 2 diabetes patients treated with GLP-1 receptor agonists compared to a control group.

Background: The utilization of PD1 and CTLA4 inhibitors has revolutionized the treatment of malignant melanoma (MM). However, resistance to targeted and immune-checkpoint-based therapies still poses a significant problem.

Objective: Here, we mine large-scale MM proteogenomic data to identify druggable targets and forecast treatment efficacy and resistance.

Ischemia/reperfusion injury (I/R) is a leading cause of acute kidney injury (AKI) in conditions like kidney transplants, cardiac surgeries, and nephrectomy, contributing to high global mortality and morbidity. This study aimed to analyze the protective effects of 2'-hydroxychalcones in treating I/R-induced AKI by targeting key pathological pathways. Considering strong antioxidant action along with other pharmacological roles of chalcone derivatives, six 2'-hydroxychalcones were synthesized via Claisen-Schmidt condensation and analyzed for their protective effects in an I/R induced AKI model using HK-2 cells.
