Placental ischemia during pregnancy induces hypertension, cerebral inflammation, and oxidative stress in dams postpartum.

Background: Preeclampsia (PE) is characterized as de novo hypertension (HTN) with end-organ damage, especially in the brain. PE is hypothesized to be caused by placental ischemia. PE affects ~5-8% of USA pregnancies and increases the risk for HTN and cerebrovascular diseases (CVD) later in life.

Postpartum Dams Exposed to a Low-Resource Environment Display Neuroinflammation, Elevated Corticosterone, and Anhedonia-like Behavior.

Women living in an impoverished environment after birth have an increased risk of developing postpartum depression (PP-Dep) and hypertension (PP-HTN). The mechanisms underlying these heightened risks are unknown and understudied. To examine the relation between reduced environmental resources, PP-Dep, and PP-HTN; postpartum rodent dams were exposed to the low-resource limited bedding and nesting (LBN) chronic stress model during weaning.

Experience with the implementation of central venous catheters by medical oncologists in a non-surgical setting.

Totally implantable central venous catheters (CVCs) are widely used in the management of patients with malignant diseases. Conventionally, port implantations were carried out by general surgeons and vascular radiologists. In recent years, the medical staff of the Medical Oncology department at the Central University Hospital of Asturias (HUCA) has developed a simplified methodology for the routine implantation of these devices.

Triatoma venosa and Panstrongylus geniculatus challenge the certification of interruption of vectorial Trypanosoma cruzi transmission by Rhodnius prolixus in eastern Colombia.

Reactivation of Trypanosoma cruzi transmission by native vectors with different domiciliation capabilities is a major concern for Chagas disease control programs. T. cruzi transmission via intra-domestic Rhodnius prolixus was certified as interrupted by the Pan American Health Organization in Miraflores municipality (Boyacá, Colombia) in 2019.

ST-elevation myocardial infarction incidence in a high-risk seismic zone.

Introduction: Earthquakes are unpredictable natural events that can elicit acute physiological responses, potentially triggering cardiovascular events. This study investigates the association between seismic activity and ST-elevation myocardial infarction (STEMI) admissions in a tertiary care hospital in an earthquake-prone region over 19 years.

Methods: We analyzed STEMI admissions at a tertiary center in Mexico City from October 2005 to August 2024.
