Objective: This study aimed to investigate the association between maternal factors and first-trimester biophysical and biochemical markers with small for gestational age (SGA) neonates in twin pregnancies (TwPs).
Methods: Single-center retrospective cohort study of TwPs followed from January 2010 to December 2022 at a tertiary perinatal center, Portugal. Maternal and pregnancy characteristics, mean arterial pressure, pregnancy-associated plasma protein-A (PAPP-A), β-human chorionic gonadotropin (β-HCG), and uterine artery pulsatility index (UtA-PI) were analyzed.

Objective: To analyze vaccination coverage up to 24 months of age according to race/ skin color in the 2017-2018 live birth cohort in Natal, Rio Grande do Norte, Brazil.
Methods: Population-based survey conducted in 2020 and 2021. Vaccination coverage up to 24 months of age was estimated according to administered, valid and timely doses.
Objective: To analyze factors associated with full vaccination coverage with valid doses, in children from four state capitals and three other cities in Southeast Brazil.
Method: Analysis of a population survey conducted in 2020-2021, with a sample stratified according to socioeconomic levels of children born in 2017-2018, with data collected through photographic records of their vaccination cards. Odds ratios (OR) and 95% confidence intervals (95%CI) for full vaccination coverage were estimated based on the characteristics of the family, mother and child.

December 2024
Objective: To analyze measles, mumps, and rubella vaccination coverage among children up to 24 months old and factors associated with non-vaccination in a 2017-2018 live birth cohort, in state capitals and large interior region cities in Northeast Brazil.
Methods: Population-based survey analyzing vaccination coverage and sociodemographic factors through logistic regression.
Results: For 12,137 children, vaccination coverage was 79.
Article Synopsis
- Therapsids were key players in ancient ecosystems and evolved into mammals during the early Mesozoic, but their origins are not well understood.
- A newly discovered partial skeleton of a gorgonopsian from Mallorca is possibly the oldest known therapsid, dating back to the lower-middle Permian period.
- Using advanced dating methods, researchers created a timeline showing that therapsids diversified rapidly after Olson's Extinction, suggesting they emerged in tropical Pangaea's wet biome rather than in cooler regions.
