Insights

Congenital malformations (CMs) impact child health significantly. This study found a prevalence of 3.91/1000 live births in Morocco, with neural tube defects and orofacial clefts being common.

Area of Science:

  • Public Health
  • Pediatrics
  • Epidemiology

Background:

  • Congenital malformations (CMs) are a significant cause of child mortality, morbidity, and disability globally.
  • Morocco has implemented a CMs surveillance system since 2011 to monitor these conditions.
  • CMs represent a substantial public health challenge, burdening healthcare systems worldwide.

Purpose of the Study:

  • To determine the prevalence of congenital malformations (CMs) in Morocco.
  • To analyze the epidemiological trends of CMs within the Moroccan population.
  • To identify specific types and geographical distribution of CMs in Morocco.

Main Methods:

  • Retrospective analysis of congenital malformations (CMs) data.
  • Utilized the national surveillance system data from 2017 to 2021.
  • Data collected from case notification forms for epidemiological assessment.

Main Results:

  • The national prevalence of congenital malformations (CMs) in Morocco was 3.91 per 1000 live births (LBs).
  • Prevalence varied annually, with a minimum of 3.10/1000 LBs in 2017 and a maximum of 4.55/1000 LBs in 2018.
  • Neural tube defects (21.13%) and orofacial clefts (10.32%) were the most common specified CMs, with unspecified CMs comprising 68.55%.

Conclusions:

  • The national prevalence of congenital malformations (CMs) in Morocco is notably high and potentially underestimated.
  • A significant proportion of reported CMs are unspecified, highlighting a need for more detailed reporting.
  • Recommendations include establishing a comprehensive CM registry and promoting preventive measures for 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...

Mechanistic Models: Compartment Models in Individual and Population Analysis

Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...
