Insights

This study found a birth defect prevalence of 11.66 per 1000 live births in Golestan Province, Iran. Cardiovascular system anomalies were the most frequent congenital anomalies observed.

Area of Science:

  • Medical research
  • Public health
  • Epidemiology

Background:

  • Congenital anomalies represent significant global health challenges.
  • Understanding the geographic and temporal variations in birth defect patterns is crucial.
  • This study focused on the prevalence and patterns of birth defects in Golestan Province, Iran.

Purpose of the Study:

  • To investigate the live birth prevalence of congenital anomalies in Golestan Province, Iran.
  • To determine the occurrence patterns of various birth defects within the studied population.
  • To compare the findings with national and international data.

Main Methods:

  • A cross-sectional descriptive study involving 144,920 live newborns from 2008 to 2013.
  • Newborn examinations for birth defects and maternal interviews for demographic data.
  • Utilized the International Classification of Diseases 10th revision-clinical modification (ICD-10-CM) for coding defects.

Main Results:

  • A total of 1690 infants had birth defects, yielding a prevalence of 11.66 per 1000 live births.
  • Cardiovascular system anomalies were the most common, with a prevalence of 8.34 per 1000 live births.
  • Prevalence rates varied slightly among different ethnic groups (Fars, Turkmen, Sistani).

Conclusions:

  • The birth defect prevalence in Golestan Province is lower than the Iranian average (20.3/1000) but higher than some Asian regions (7.33/1000).
  • Findings highlight the importance of regional surveillance for congenital anomalies.
  • Further research into contributing factors for observed patterns is warranted.

Birth Control Methods01:22

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Lumber Defects01:23

Lumber Defects

Lumber defects, which can affect both the appearance and structural integrity of wood, include a variety of growth and manufacturing flaws. Growth defects such as knots and knotholes occur where branches were once attached to the tree trunk, with knotholes forming when these knots fall out. Other natural defects include decay and insect damage, which compromise the wood's strength and durability.
Shakes are minor fractures that run along or across the wood's annual rings, while wane is...

Imprinting01:22

Imprinting

Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

Reproductive Cloning01:27

Reproductive Cloning

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

Nondisjunction01:29

Nondisjunction

During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.

Conservation of Small Populations02:04

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...
