Sexually Transmitted Infections01:26

Sexually Transmitted Infections

270
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Sex-linked Disorders01:43

Sex-linked Disorders

100.3K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Genomic Imprinting and Inheritance

33.2K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Chromosomal Theory of Inheritance

In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

Teratogenicity01:07

Teratogenicity

2.3K
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...

Meiosis vs. Mitosis02:57

Meiosis vs. Mitosis

52.7K
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...

Summary

Timely diagnosis and adequate treatment are crucial for preventing congenital syphilis (CS). Late maternal diagnosis and high nontreponemal titers increase CS risk, while proper treatment offers protection.

Area of Science:

  • Infectious Diseases
  • Maternal Health
  • Pediatrics

Background:

  • Congenital syphilis (CS) is a significant global health concern, characterized by Treponema pallidum transmission during pregnancy.
  • A concerning increase in CS prevalence has been noted since 2001, particularly in low- and middle-income nations.
  • Risk factors contributing to this rise in congenital syphilis remain under-investigated.

Purpose of the Study:

  • To identify and analyze the key risk factors associated with congenital syphilis.
  • To provide evidence-based insights for developing effective prevention and intervention strategies.

Main Methods:

  • A case-control study design was employed.
  • Data were extracted from clinical records of 297 mothers diagnosed with syphilis between 2016 and 2024 in Monterrey, Mexico.
  • Statistical analysis utilized multivariable logistic regression via SPSS V.22.

Main Results:

  • Late maternal diagnosis, particularly after childbirth, significantly elevates the risk of congenital syphilis (OR: 4.352).
  • Mothers with high nontreponemal serum test titers (≥1:8) exhibited a substantially increased risk of transmitting syphilis to their infants (OR: 4.380).
  • Adequate treatment administered to mothers was identified as a significant protective factor against congenital syphilis (OR: 0.213).

Conclusions:

  • Congenital syphilis represents a critical global public health challenge requiring urgent attention.
  • Effective maternal treatment is paramount in preventing congenital syphilis transmission.
  • Strengthening prenatal care, promoting early diagnosis, and ensuring adequate treatment for high-risk mothers are essential public health strategies.
