Objective: We investigated whether the auditory system of newborn babies extracts the constancy of a pitch interval from exemplars varying in absolute pitch.
Methods: Event-related brain potentials (ERP) were recorded from healthy newborn infants in an oddball paradigm consisting of frequent standard and infrequent deviant tone pairs. Tone pairs varied in absolute frequency. Standard and deviant pairs differed in the amount of pitch difference within the pairs, but not in the direction of pitch change.
Results: Deviant tone pairs elicited a discriminative ERP response.
Conclusions: This result suggests that the neonate auditory system represents pitch intervals similarly to adults.
Significance: Adult-like processing of pitch intervals allows newborn infants to learn music, speech prosody, and to process various important auditory cues based on spectral acoustic features.

Health Promotion Division, Public Health Foundation of India, New Delhi, Delhi, 110030, India.
Background: The Indian government is committed to addressing various manifestations of malnutrition, including overweight and obesity, inorder to improve individual health and well-being. The scoping review aims to map existing national policy instruments (programmes, schemes, regulations and guidelines) addressing overweight and obesity in India and analysing them for Social and Behaviour Change Communication (SBCC) strategies.
Methods: Systematic identification and selection of policy instruments using 'Arksey and O'Malley' framework was conducted from central government ministry websites, between March and June 2023.

Objective: The objective is to analyze secular trends in birth weight (BW) for Chile from 1990 to 2021, focusing on the mean BW and low birth weight (LBW) prevalence, and to assess differences across Chilean regions.
Methods: Our sample, obtained from the Chilean National Statistics Office, contains information on 7 822 975 births, including the total births that took place in Chile from 1990 to 2021. We calculated mean BW and LBW prevalence at a national and a regional level.
The effect of STI screening during pregnancy on vertical transmission of HIV and adverse pregnancy outcomes in South Africa: a modelling study.

Centre for Integrated Data and Epidemiological Research, School of Public Health, University of Cape Town, Cape Town, South Africa.
Introduction: Sexually transmitted infections (STIs) in pregnancy are associated with an increased risk of vertical HIV transmission and adverse pregnancy and birth outcomes. In South Africa, syndromic management is the standard of care for STI management. We assessed the potential impact of point-of-care (POC) screening for curable STIs (Chlamydia trachomatis [CT], Trichomonas vaginalis [TV] and Neisseria gonorrhoeae [NG]) during pregnancy on vertical HIV transmission and adverse pregnancy and birth outcomes.
