Fetal Circulation01:14

Fetal Circulation

2.5K
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...

Teratogenicity01:07

Teratogenicity

3.9K
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...

Classification of Illness01:17

Classification of Illness

8.5K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

1.3K
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:

Nursing Diagnosis01:22

Nursing Diagnosis

3.6K
Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
The nursing diagnosis focuses on evidence-based...

Summary
This summary is machine-generated.

The Causes of Death and Associated Condition (CODAC) system significantly reduced unspecified stillbirths in Brazil compared to ICD-10. This classification system aids in understanding stillbirth causes and informing health policies.

Area of Science:

  • Perinatal Medicine
  • Public Health
  • Medical Classification Systems

Background:

  • Stillbirth remains a significant global health challenge, with a substantial proportion of cases classified under nonspecific or unspecified causes.
  • Accurate classification of stillbirth is crucial for identifying underlying causes and implementing effective preventive strategies.
  • The current ICD-10 system in Brazil has limitations in specifying stillbirth etiologies.

Purpose of the Study:

  • To compare the effectiveness of the Causes of Death and Associated Condition (CODAC) classification system against the ICD-10 system in reducing unspecified stillbirths in Brazil.
  • To identify maternal and pregnancy-related factors associated with stillbirth in the Brazilian population.

Main Methods:

  • A retrospective cross-sectional study analyzed 2545 stillbirth cases from ten tertiary obstetric facilities in Brazil (2009-2018).
  • Data were sourced from medical records, death certificates, and postmortem investigations.
  • The CODAC system was applied, and its performance was compared to ICD-10 using kappa coefficient and McNemar's test.

Main Results:

  • The CODAC system reduced the proportion of unspecified stillbirths from 40.79% (ICD-10) to 22.00%.
  • Significant regional disparities were observed, with higher rates of unspecified causes in the northeast and specific causes in the southeast.
  • Maternal conditions like preeclampsia and placental abruption were significantly associated with specific causes of stillbirth identified by CODAC.

Conclusions:

  • The CODAC classification system offers improved understanding of stillbirth causes compared to the ICD-10 system.
  • Implementing CODAC can decrease the number of unexplained stillbirth cases, potentially enhancing maternal and perinatal health policies in Brazil.
