Chronic Kidney Disease II: Clinical Manifestations01:24

Chronic Kidney Disease II: Clinical Manifestations

520
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Coronary Artery Disease III: Clinical Manifestations

299
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Endocarditis II: Clinical Features of Infective Endocarditis

364
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart Failure III: Clinical Manifestations

436
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

652
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Hypertension III: Clinical Manifestations and Diagnostic Studies01:30

Hypertension III: Clinical Manifestations and Diagnostic Studies

437
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Area of Science:

  • Gerontology
  • Cognitive Science
  • Health Informatics

Background:

  • Digital cognitive assessment tools are increasingly used, but digital literacy is often overlooked.
  • Existing digital literacy scales are complex and time-consuming for older adults.
  • A need exists for a simple pre-assessment tool for digital cognitive evaluations in this demographic.

Purpose of the Study:

  • To develop and validate a Brief Digital Literacy Scale (BDLS) for older adults.
  • To provide a simple, quick tool for assessing digital literacy prior to digital cognitive testing.
  • To explore the relationship between digital literacy and cognitive status in older adults.

Main Methods:

  • The BDLS, a 10-item scale, was administered to 202 older adults (cognitively normal, mild cognitive impairment, Alzheimer's disease).
  • Internal consistency, exploratory factor analysis (EFA), regression, and partial correlation analyses were conducted.
  • Participants were recruited from the Gwangju Alzheimer's Disease and Related Dementia Cohort in Korea.

Main Results:

  • The BDLS demonstrated excellent internal consistency (α=0.874) and a three-factor structure (Technical Proficiency, Smart Device Usage, Digital Usage Frequency/Information Evaluation).
  • Higher BDLS scores correlated with younger age and more education; no significant gender differences were found.
  • BDLS scores showed significant partial correlations with traditional cognitive tests (naming, visual memory, psychomotor speed) and digital cognitive scores (visual memory, processing speed), and differed significantly across cognitive status groups.

Conclusions:

  • The BDLS is a reliable and valid tool for assessing digital literacy in older adults.
  • Digital literacy, particularly visual memory and naming abilities, is linked to cognitive performance in both digital and traditional formats.
  • The BDLS offers a practical pre-assessment solution for digital cognitive testing, emphasizing the importance of digital literacy in research and clinical settings.
