Introduction: COVID-19 exposure during pregnancy is hypothesized to affect the birth weight of the children. Community based findings on such hypothesis are scarce in West Bengal. This study was conducted with the objective to determine the relationship between low birth weight (LBW) and maternal exposure to COVID-19.
Materials And Methods: In this retrospective cohort study, mothers of children, who were born between February 2020 and October 2021 and who were registered in the subcenters of Purba Barddhaman district, West Bengal, were selected as study population. Mothers who were diagnosed as COVID-19 positive during the antenatal period were considered as 'Pregnancy with COVID' and others were considered as 'Pregnancy without COVID'. The minimum required sample size using Fleiss formula were 119 and 476, respectively, whose were selected through multi-stage random sampling. A schedule was used to collect data through review of relevant records of antenatal registers of sub-centers of selected individuals. The association was checked through multivariate logistic regression model where < 0.05 was considered statistically significant.
Results: Incidence of LBW in COVID pregnancy, Non-COVID Pregnancy group were 30.3% and 18.7%, respectively. COVID positivity during pregnancy shows relative risk of 1.62 and attributable risk of 38.28% for LBW baby as pregnancy outcome. Multivariate analysis reveals that LBW babies are significantly associated with COVID status during pregnancy (AOR 2.18, 1.3-3.63) after adjusting for anemia in pregnancy, incomplete antenatal visits, mothers age ≥30 years, parity and periods of gestation.
Conclusion: The study concludes that COVID positivity during pregnancy significantly increases the risk of LBW as pregnancy outcome.

Introduction: Consuming hypercaloric diets during pregnancy induces metabolic, immune, and maternal intestinal dysbiosis disorders. These conditions are transferred to the offspring through the placenta and breastfeeding, increasing susceptibility to metabolic diseases. We investigated the effect of GG supplementation on offspring maternally programmed with a hypercaloric diet.

In response, based on three attention networks: alerting, orienting, and executive attention, we examined the development of attention functions at 42 months (not corrected for prematurity) as a follow-up study of VLBW ( = 23) and normal birth weight (NBW: = 48) infants.
Method: The alerting and orienting attention networks were examined through an overlap task with or without warning signal.

Background: Osteocalcin is a metabolic active hormone, which correlates positively with bone formation and inversely with body mass index and waist circumference in adults.
Objectives: To investigate whether osteocalcin in infancy and early childhood were related to childhood growth or body composition.
Methods: A Swedish longitudinal birth cohort with blood samples from 551 children from birth until 5 years of age.

Backgrounds: Many pregnant women suffer from more than one pregnancy complication. However, whether those women experienced a higher risk of adverse birth outcomes is unclear. This study aims to assess the association between the comorbidity of gestational diabetes mellitus (GDM) and hypertension disorders of pregnancy (HDP) and adverse birth outcomes.

Background: Necrotising enterocolitis (NEC) is life-threatening with a rising incidence due to improved neonatal care. While researchers' focus has shifted to causes, risk factors and preventative clinical strategies, little is known about the exact aetiology of NEC. Risk factors include the relationship between red blood cell transfusions (RBCTs) and the development of transfusion-associated NEC (TANEC) and peri-transfusion feeding, increasing the risk of TANEC.
