Summary
Microcephaly (MC), a condition of deficient brain growth, is linked to disadvantaged sociodemographic factors. Early identification using a head circumference standard deviation score of ≤-2 is recommended, as some cases resolve but persistent MC impacts development.
Area of Science:
- Pediatrics
- Developmental Neuroscience
- Public Health
Background:
- Microcephaly (MC) is a critical indicator of impaired brain growth.
- Understanding risk factors and developmental trajectories is essential for early intervention.
Purpose of the Study:
- To investigate the sociodemographic risk factors associated with microcephaly (MC).
- To analyze the follow-up features and developmental outcomes of children diagnosed with MC.
Main Methods:
- Retrospective cohort study of 7580 children's health records (2002-2020).
- MC defined as head circumference (HC) standard deviation score (SDS) ≤-2 SDS.
- Age and sex-matched controls with normal HC were used for comparison.
Main Results:
- Children with MC exhibited more disadvantaged sociodemographic characteristics (e.g., young parental age, lower education).
- Breastfeeding was more prevalent in the control group.
- MC resolved in 53.1% of cases; persistent MC was associated with poorer developmental milestones.
Conclusions:
- Defining MC as HC SDS ≤-2 is appropriate for effective follow-up.
- Addressing sociodemographic inequalities may help prevent MC.
- Further research into socioeconomic factors influencing MC is warranted.

01:07Teratogenicity
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...
01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
01:28Development 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,...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
