Insights

Newborn hearing screening (NHS) is vital. Key risk factors for congenital hearing loss (CHL) include mechanical ventilation, family history of CHL, and consanguinity, highlighting the need for targeted screening.

Area of Science:

  • Pediatrics
  • Audiology
  • Genetics

Background:

  • Congenital hearing loss (CHL) is a common birth defect.
  • Early detection of CHL is crucial for timely intervention and improved outcomes.
  • Newborn Hearing Screening Programs (NHSP) aim to identify infants with hearing loss shortly after birth.

Purpose of the Study:

  • To evaluate the effectiveness of the newborn hearing screening program (NHSP) at a specific institute.
  • To identify and analyze risk factors associated with congenital hearing loss (CHL).
  • To determine the correlation between identified risk factors and CHL in newborns.

Main Methods:

  • A prospective study involving 1000 consecutive newborns undergoing NHSP from June 2014 to December 2014.
  • Parents completed questionnaires detailing potential risk factors for CHL.
  • NHSP results and referral rates were analyzed and compared against reported risk factors.

Main Results:

  • The overall referral rate for the NHSP was 3.5%.
  • Significant correlations were found between CHL and mechanical ventilation, a history of familial CHL, and familial consanguinity.
  • These risk factors are critical indicators for potential congenital hearing loss.

Conclusions:

  • Universal newborn hearing screening is mandatory for early detection of hearing impairment.
  • Targeting identified risk factors and educating families on follow-up is essential for diagnosing delayed-onset hearing loss.
  • Effective NHSP implementation aids in managing congenital hearing loss and its long-term effects.

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...

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Relative Risk01:12

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Transcription Factors02:16

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Multiple Comparison Tests01:13

Multiple Comparison Tests

Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
