Article Synopsis
  • Malnutrition in early childhood can lead to long-term health issues, including obesity, with this study focusing on how maternal perceptions and feeding practices influence infant nutrition in northeastern Mexico.
  • The research assessed 192 mother-infant pairs, revealing that 38% of infants were overweight/obese while 7% were underweight, and identified key maternal factors like low self-efficacy and inaccurate weight perceptions affecting infant nutritional status.
  • Findings suggest that many mothers lack knowledge about proper feeding practices, with longer sleep duration linked to underweight infants and critical inaccuracies in maternal perceptions of their child’s weight for both underweight and overweight/obese infants.

Article Synopsis
  • Honey bees are vital for pollination but face threats from invasive subspecies, pathogens, and parasites, highlighting the need for better identification tools.
  • The introduction of HBeeID provides a powerful tool for identifying different honey bee subspecies using genomic data and diagnostic SNPs, even with incomplete samples.
  • HBeeID is adaptable for future improvements and can help monitor invasive honey bee species, aiding ecological management efforts.

Background: To evaluate the efficacy and safety of upadacitinib monotherapy versus methotrexate (MTX) monotherapy over 5 years among MTX-naïve patients with moderately to severely active rheumatoid arthritis (RA) in the long-term extension (LTE) of the phase 3 SELECT-EARLY trial.

Methods: Patients were randomized to receive upadacitinib 15 mg or 30 mg or MTX. Patients who did not achieve CDAI remission and had < 20% improvement in tender and swollen joint counts at week 26 received rescue therapy (addition of MTX in the upadacitinib group and addition of upadacitinib in the MTX group).
