Adjuvant Therapy in Early Uterine Serous Carcinoma.

Objective: Uterine serous carcinoma (USC) is a rare diagnosis but associated with high mortality. There is limited data to guide adjuvant treatment decisions in early stage disease. The purpose of this study is to evaluate the impact of adjuvant therapy on recurrence-free survival (RFS) and overall survival (OS) in early stage USC.

Alterations in newborn metabolite patterns with preterm birth and diabetes in pregnancy.

Background: This study examines the influence of prematurity and diabetes (DM) in pregnancy on metabolite patterns at birth, and associations with adiposity development in a prospective cohort.

Methods: Term and preterm (30-36 weeks gestational age [GA]) infants were enrolled and body composition assessments completed through discharge. Targeted metabolomics was used to assess metabolites in cord or infant blood in the first 2 days.

Evidence for Endogenous Collagen in Fossil Bone.

Reports of proteins in fossilized bones have been a subject of controversy in the scientific literature because it is assumed that fossilization results in the destruction of all organic components. In this paper, a novel combination of analytical techniques is used to address this question for an exceptionally well-preserved sacrum excavated from the Upper Cretaceous strata of the South Dakota Hell Creek Formation. Cross-polarized light microscopy (XPol) shows birefringence consistent with collagen presence.

The Impact of Air Pollution on Cardiovascular Health Outcomes in African Populations: A Scoping Review.

Background: Air pollution is a significant environmental risk factor for cardiovascular diseases (CVDs), but its impact on African populations is under-researched due to limited air quality data and health studies.

Objectives: The purpose of this study was to synthesize available research on the effects of air pollution on CVDs outcomes in African populations, identify knowledge gaps, and suggest areas for research and policy intervention.

Methods: A systematic search of PubMed was conducted using terms capturing criteria ambient air pollutants (for example particulate matter, nitrogen dioxide, ozone, and sulfur dioxide) and CVDs and countries in Africa.

Role of neck dissections in the management of carotid body tumors.

Objective: Carotid body tumors (CBTs) are rare neoplasms of the paraganglia at the carotid bifurcation. While typically benign, CBTs occasionally exhibit malignancy, metastasizing to nearby lymph nodes. Histopathologic analysis alone is insufficient to confirm malignancy, requiring metastases to non-neuroendocrine tissue for a definitive diagnosis.
