Multivariate regression analysis identified key independent risk factors for FTT, including rural residence, incomplete or lack of immunization, absence of exclusive breastfeeding, and lack of timely complementary feeding. This study underscores the significant role of rural residency, inadequate immunization, absence of exclusive breastfeeding, and delayed complementary feeding in increasing the risk of FTT among infants aged 2-12 months in rural North India.

We determined anti-Pertussis Toxin (PT) and anti-measles IgG in 86 6-week-old infants, born to mothers living with HIV (HIV-exposed uninfected, HEU, n = 58) and to HIV-negative mothers (HIV-unexposed uninfected, HUU, n = 28). The HEU group was divided into two subgroups: Infants born to mothers who initiated antiretroviral therapy (ART) during pregnancy (Short-ART, SA-HEU group, n = 29) or already in stable ART (Long-term ART, LA-HEU group, n = 29). The mean anti-PT and anti-measles IgG levels (1.97 IU/ml and 32.9 mIU/ml, respectively) were comparable between the HUU and HEU infants. Overall, only 12.8% and 18.6% of all infants had IgG levels above the protective thresholds for pertussis and measles, respectively. The duration of ART significantly influenced the infant's serological profile, with SA-HEU infants showing significantly lower IgG levels compared to both HUU and LA-HEU infants.

A single-center observational study enrolled 104 children admitted to a PICU from January to September 2021. Demographic details, past medical history, Pediatric Index of Mortality-3 scores, sedation, inotrope administration, ventilator-associated pneumonia (VAP), new-onset shock, respiratory failure, sepsis, renal failure, new or progressive multiple organ dysfunction syndrome (MODS), and duration of ventilation were recorded.
