Insights

Newborn hearing screening identified 1.5 per 1000 infants with hearing impairment. Early intervention with hearing aids or cochlear implants is crucial for affected infants.

Area of Science:

  • Audiology
  • Neonatal Care
  • Public Health

Background:

  • Hearing impairment affects newborns, necessitating early detection.
  • A study was conducted in Babol, Iran, to assess newborn hearing screening outcomes.

Purpose of the Study:

  • To investigate the results of hearing screening in newborn infants.
  • To evaluate the follow-up process for infants diagnosed with hearing impairment.

Main Methods:

  • A cross-sectional study included 40,930 healthy neonates from 2006-2014.
  • Transient evoked otoacoustic emissions (TEOAE) screening was performed before discharge.
  • Follow-up involved auditory brainstem response (ABR), auditory steady state response, and impedance audiometry.

Main Results:

  • 62 infants (1.5 per 1000 live births) were diagnosed with hearing impairment.
  • 15 infants received hearing aids and 18 underwent cochlear implantation.
  • 2.4% of infants were lost to follow-up; 0.03% died within 3 months.

Conclusions:

  • Universal newborn hearing screening before discharge is recommended.
  • Supportive measures for hearing impairment should commence at 3 months.
  • Re-examination at 12 months of age is advised for infants with hearing impairment.

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.

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...

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Guidelines for Writing Outcome

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
