Fetal Circulation01:14

Fetal Circulation

2.1K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Population Growth00:57

Population Growth

27.6K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

2.6K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

Teratogenicity01:07

Teratogenicity

3.8K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

1.1K
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Prevalence and Incidence01:08

Prevalence and Incidence

1.4K
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Summary

Maternal mortality in Brazil is linked to occupation, with domestic and agricultural workers facing higher risks. Further research is needed to understand occupational and socioeconomic factors contributing to these disparities.

Area of Science:

  • Public Health
  • Epidemiology
  • Occupational Health

Background:

  • Maternal mortality remains a significant public health concern globally.
  • Understanding disparities in maternal mortality is crucial for targeted interventions.
  • Occupation is a potential social determinant of health influencing maternal outcomes.

Purpose of the Study:

  • To estimate the maternal mortality ratio (MMR) across different occupational groups in Brazil.
  • To identify specific occupations with elevated maternal mortality risks.

Main Methods:

  • A mortality study utilizing national data from the Mortality Information System (SIM) and Live Birth Information System (SINASC) for 2015.
  • Maternal mortality ratios were calculated based on occupation data from death certificates, classified using the Brazilian Classification of Occupation (CBO) 2002.
  • Analysis of 1,738 maternal death records.

Main Results:

  • The overall maternal mortality ratio in Brazil was 57.6 per 100,000 live births.
  • Significantly higher MMRs were observed among service and agricultural workers, notably domestic workers (123.2/100,000) and general agricultural workers (88.3/100,000).
  • Manicurists and nursing technicians also showed elevated MMRs; however, occupation data were missing or inconsistent in a substantial proportion of records, with 'Housewife' being the most frequent category.

Conclusions:

  • Maternal mortality ratios vary significantly by occupation in Brazil, indicating a potential contribution of work-related factors.
  • Further research is essential to investigate occupational risk factors, socioeconomic determinants, workplace exposures, and healthcare access in relation to maternal mortality.
  • Addressing the interplay of socioeconomic status, occupational exposures, and healthcare access is critical for reducing maternal mortality disparities.
