Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...
Primary Motives: Sleep, Sex, and Pain Avoidance01:24

Primary Motives: Sleep, Sex, and Pain Avoidance

Primary motives such as sleep, sex, and pain avoidance are crucial drivers of behavior in humans and animals. These motives ensure survival, reproductive success, and overall well-being by prompting actions that meet essential bodily needs.
Sleep is a fundamental physiological drive that fosters a state of restfulness crucial for several bodily functions. It facilitates body restoration, the process by which the body repairs, rejuvenates, and maintains itself during sleep, including memory...
Panic Disorder01:27

Panic Disorder

Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...
Other Pulmonary Disorders01:17

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
Socioemotional Experience and Gender Development01:30

Socioemotional Experience and Gender Development

Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...
Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Summary

Women with obstructive sleep apnoea (OSA) treated with continuous positive airway pressure (CPAP) faced significantly higher mortality risk than men, primarily due to greater comorbidity. This highlights a critical disparity in OSA outcomes.

Drug-Induced Sleep Endoscopy (DISE) with Target Controlled Infusion (TCI) and Bispectral Analysis in Obstructive Sleep Apnea

Published on: December 6, 2016

Area of Science:

  • Medicine
  • Pulmonology
  • Sleep Medicine

Background:

  • Obstructive sleep apnoea (OSA) is a common condition affecting sleep quality and potentially long-term health.
  • Continuous positive airway pressure (CPAP) is a standard treatment for OSA.
  • Sex-based differences in OSA prevalence and severity are recognized, but mortality risk disparities require further investigation.

Purpose of the Study:

  • To compare the mortality risk between men and women diagnosed with OSA and initiated on CPAP therapy.
  • To identify factors associated with increased mortality risk in OSA patients undergoing CPAP treatment.

Main Methods:

  • Retrospective review of hospital records for patients who started CPAP for OSA between July 1995 and June 1998.
  • Comparison of mortality rates between male and female patient cohorts.
  • Univariate and multivariate Cox's proportional hazards regression analyses to determine associations with mortality risk.

Main Results:

  • The study included 292 men and 47 women; 8% of men and 23% of women died (p=0.003).
  • Factors associated with increased mortality included female sex, older age at CPAP initiation, low pre-treatment SpO(2) (<75%), higher Charlson comorbidity index, and CPAP discontinuation.
  • Female sex remained an independent risk factor for mortality, except when considering the Charlson score. Women exhibited a 3.44-fold higher mortality risk than men, largely attributed to comorbidities.

Conclusions:

  • Women with OSA treated with CPAP have a substantially higher mortality risk compared to men.
  • Greater comorbidity burden in women is the primary driver of this increased mortality.
  • Clinical management of OSA in women may need to consider sex-specific factors and comorbidity profiles more closely.
