Impact of the COVID-19 pandemic on cancer mortality in Brazil.

Background: In the first year of the COVID-19 pandemic, data projections indicated an increase in cancer mortality for the following years due to the overload of health services and the replacement of health priorities. The first studies published with data from mortality records have not confirmed these projections. However, cancer mortality is not an outcome that occurs immediately, and analyses with more extended follow-up periods are necessary.

Social Inequalities in Child Development: Analysis of Low-Birth-Weight Trends in Brazil, 2010-2020.

Introduction: Low birth weight (LBW) is a global issue prevalent in low-income countries. Economic assessments of interventions to reduce this burden are crucial to guide health policies. However, there is a relative scarcity of research that illustrates the magnitude of LBW by country and region to support the design of public policies.

How oral health literacy and parental behavior during the meals relate to dental caries in children.

This cross-sectional study aimed to verify the influence of parental behavior on the development of dental caries in children by assessing parents' behavior during their children's meals and their parental level of oral health literacy. This study was conducted with children aged 2 to 4 in Diadema, São Paulo, Brazil. Six hundred and thirty children were examined to assess the prevalence of dental caries (dmft index).

Impact of redistributing deaths by ill-defined causes in oral and oropharyngeal cancer mortality in Brazil.

Less-than-optimal reliability of mortality information systems regarding the underlying cause of death can mask the reality of oral (OC) and oropharyngeal cancer (OPC) mortality. This study aimed to assess the impact on the magnitude and temporal trends of OC and OPC mortality in Brazil of two statistical approaches to redistribute deaths with ill-defined underlying causes. We analyzed deaths with ill-defined causes in Brazil by macro-region, between 1996-2018.

The tendency of stunting among children under five in the Northern Region of Brazil, according to the Food and Nutrition Surveillance System, 2008-2017.

Objective: To analyze the temporal tendency of stunting prevalence among children under five years of age registered in the Food and Nutritional Surveillance System (SISVAN) in the Brazilian Northern Region, from 2008 to 2017.

Methods: Ecological time-series study with data from SISVAN. The annual variation rate for the prevalence of undernutrition, measured by the presence of stunting (low height-for-age index), was estimated for the Northern Region and for each of its states using the Prais-Winsten regression model with and without variable adjustment for SISVAN coverage to explore the relationship between these variables.

Relationship between oral health literacy of caregivers and the oral health-related quality of life of children: a cross-sectional study.

Background: Oral health literacy is the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate oral health decisions. However, scientific evidence about the oral health literacy of caregivers and the children's oral health-related quality of life. The purpose of this study was to verify the relationship between the level of oral health literacy of caregivers and the children's oral health-related quality of life (OHRQOL).

Approaches to the problem of nonidentifiability in the age-period-cohort models in the analysis of cancer mortality: a scoping review.

Aiming to detect age, period and cohort effects in cancer mortality, age-period-cohort models (APC) can be applied to distinguish these effects. The main difficulty with adjusting an APC model involving age, period and cohort factors is the linear relationship between them, leading to a condition known as the 'nonidentifiability problem'. Many methods have been developed by statisticians to solve it, but there is not a consensus.

The impact of inequalities and health expenditure on mortality due to oral and oropharyngeal cancer in Brazil.

This study aims to assess the magnitude and trend of mortality rates due to oral (OC) and oropharyngeal cancer (OPC) in the 133 Intermediate Geographic Regions (IGR) of Brazil between 1996 and 2018 and to analyze its association with sociodemographic variables and provision of health services. It also aims to compare the trend of mortality from neoplasms that have been reported as associated with HPV (OPC) with the trend of neoplasms that have been reported as not associated with HPV (OC). We obtained mortality data from the Mortality Information System in Brazil and analyzed the trends using the Prais-Winsten method.

The impact of the COVID-19 pandemic on the provision of dental procedures performed by the Brazilian Unified Health System: a syndemic perspective.

Objectives: This study investigated the impact of the COVID-19 pandemic on the provision of dental care procedures performed by the Brazilian Unified Health System (SUS) nationally and by regions. Considering that the most underprivileged population disproportionately suffers with the reduction in dental care provision, the study hypothesis suggests the presence of a syndemic nature.

Methodology: The SUS Outpatient Information System (SIA-SUS) was assessed to gather data on dental care activities and procedures performed between April and July 2018, 2019, and 2020 by dentists registered in the SUS.
