The Relationship of Preterm, Term, and Post-Term Births to Maternal Stress and Human Milk Cortisol Levels.

Maternal stress can lead to changes in the composition of human breast milk. The present study evaluates cortisol levels in the breast milk of mothers after giving birth preterm, term, or post-term, and ascertains whether the levels are associated with maternal stress. Included in the study were mothers who gave birth vaginally after 32 weeks of gestation between January and April 2022.

Role of Systemic Immune-Inflammatory Index in Predicting the Development of In-Hospital Malignant Ventricular Arrhythmia in Patients With ST-Elevated Myocardial Infarction.

Many complications can be observed after ST-elevation myocardial infarction (STEMI). The systemic immune-inflammatory index (SII) is a sensitive indicator of the inflammatory state, and this parameter may also be associated with cardiovascular diseases. In this study, we investigated the relationship between malignant ventricular arrhythmias (MVA) development and SII in STEMI patients.

Does new onset and pre-existing atrial fibrillation predict mortality in COVID-19 patients?

Background: Coronavirus Disease-2019 (COVID-19), caused by Severe Acute Respiratory Syndrome-Coronavirus-2, still remains prevalent and severe. We aimed to evaluate the effects of pre-existing atrial fibrillation and new-onset atrial fibrillation (NOAF) on the clinical severity and mortality of COVID-19.

Results: Between April and December 2020, 5577 patients with positive PCR and/or COVID-19 compatible findings in computed tomography hospitalized were enrolled retrospectively.
