    Insights

    Congenital malformations are an increasing cause of infant mortality. Key risk factors include low birth weight, advanced maternal age, and maternal illness during pregnancy, while maternal education showed a protective effect.

    Area of Science:

    • Perinatal Health
    • Birth Defects Research
    • Public Health

    Context:

    • Congenital malformations (birth defects) represent a growing cause of infant mortality as other perinatal issues are controlled.
    • Understanding risk factors is crucial for developing targeted interventions and improving infant survival rates.

    Purpose:

    • To identify and analyze risk factors associated with congenital malformations.
    • To investigate factors influencing the severity of congenital malformations.

    Summary:

    • This retrospective case-control study analyzed data from The Latin American Collaborative Study of Congenital Malformations (ECLAMC) between 2001 and 2010.
    • Identified risk factors include lower birth weight, shorter gestational age, advanced maternal age, fetal growth retardation, family history of malformations, maternal physical factors, and maternal illness in early pregnancy.
    • Higher maternal educational level was found to be a protective factor against congenital malformations and their severity.

    Impact:

    • Findings highlight the importance of prenatal care, maternal health, and socioeconomic factors in preventing birth defects.
    • Provides evidence for targeted public health strategies to reduce infant mortality due to congenital malformations.

    Teratogenicity01:07

    Teratogenicity

    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...

    Development of the Oral Microbiota

    The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

    Cancer Prevention

    Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

    Factors Affecting the Risk of Infection01:26

    Factors Affecting the Risk of Infection

    The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
    The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

    Meiosis vs. Mitosis02:57

    Meiosis vs. Mitosis

    Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
    Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

    Nondisjunction01:21

    Nondisjunction

    Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers.  Nondisjunction is common during anaphase I or anaphase II of meiosis.  Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...
