Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

224
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...

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

1.6K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

225
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

431
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Insomnia01:27

Insomnia

133
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.
Multiple factors contribute...

Summary
This summary is machine-generated.

Self-reported sleep issues, not objective measures, correlate with fatigue in rheumatoid arthritis (RA) patients. Addressing subjective sleep quality is key for improving RA patient outcomes.

Area of Science:

  • Rheumatology
  • Sleep Medicine
  • Patient-Reported Outcomes

Background:

  • Fatigue is a common and disabling symptom in rheumatoid arthritis (RA).
  • While inflammation is often cited, sleep disturbances are frequently overlooked as a cause of RA fatigue.
  • Understanding the relationship between sleep and fatigue is crucial for effective RA management.

Purpose of the Study:

  • To investigate the association between subjective and objective sleep parameters and self-reported fatigue in RA patients.
  • To determine if objective sleep measures align with patient-reported fatigue levels.

Main Methods:

  • Cross-sectional study of 48 adult RA patients.
  • 14-day sleep assessment using actigraphy (objective) and Karolinska Sleep Diary (subjective).
  • Fatigue measured by PROMIS fatigue computerized adaptive test; analyzed with Spearman correlations and linear regression.

Main Results:

  • Subjective sleep parameters (duration, efficiency, quality) significantly correlated with lower fatigue levels.
  • Objective actigraphy-based sleep parameters did not show a significant association with fatigue.
  • Subjective sleep parameters remained significant predictors of fatigue after adjusting for covariates.

Conclusions:

  • Self-reported sleep disturbances are strongly linked to fatigue in RA patients.
  • Objective sleep measures did not correlate with fatigue, suggesting subjective reporting is critical.
  • Integrating self-reported sleep assessments into RA treatment plans may improve patient outcomes.
