Objective: To examine the association between the lifetime utilisation of dental services and dental caries experience in mixed dentition among adolescents participating in the 2004 Pelotas Birth Cohort, Southern Brazil.
Methods: This longitudinal study analysed a sample of 996 adolescents aged 12-13 years. Dental caries experience and untreated dental caries were the outcomes, assessed by the mean of decayed, missed and filled in deciduous (dmfs index) and in permanent (DMFS index) teeth, based on World Health Organization criteria.
Impact of COVID-19 on the utilisation of maternal and child health services in Peru at national and subnational levels: An interrupted time series analysis.

Article Synopsis
- The political crisis in Peru, starting in 2016, weakened the health system, which was further tested by the COVID-19 pandemic, affecting maternal and child health (MCH) services.
- A study analyzing health facility data revealed a significant drop in the use of MCH services in 2020, particularly in antenatal care and skilled birth assistance, with the most affected region being the Rainforest.
- Despite the decline in 2020, service utilization rebounded in 2021, returning to pre-pandemic levels, emphasizing the importance of enhancing health system resilience for future challenges.
Objective: Children with intellectual disability (ID) usually exhibit neuroendocrine functioning impairment, such as alterations in the hypothalamic-pituitary-adrenal (HPA) neuroendocrine axis, which can result in glucocorticoid cortisol release alterations. Indeed, many studies showed a positive association between ID and cortisol concentration. However, evidence is lacking on the relationship between child neurodevelopment and cortisol levels during adolescence in population-based studies.

- The COVID-19 pandemic significantly disrupted maternal health care services in Bangladesh, with notable declines in service utilization across the country compared to the pre-pandemic period from 2017 to 2019.
- The study analyzed data from January 2017 to December 2021 to assess the trends in first antenatal visits, institutional deliveries, and caesarean sections, revealing about a 30% overall decrease in these services during the pandemic.
- Geographical disparities were evident, with the Chattogram and Rajshahi divisions showing the lowest rates of maternal health service utilization, especially in 2020 and 2021, indicating a pronounced impact of the pandemic on specific regions.
We aimed to test the association between sleep-related polygenic scores (PGSs) and accelerometer-based sleep metrics among Brazilian adolescents and to evaluate potential mechanisms underlying the association through the enrichment of obesity, and cortisol pathway-specific polygenic scores (PRSet). Utilizing data from The 2004 Pelotas (Brazil) Birth Cohort, sleep time window and sleep efficiency were measured at the 11-year-old follow-up using ActiGraph accelerometers. Three sleep PGSs were developed based on the most recent genome-wide association study of accelerometer-based sleep measures.
