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 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...

Área de la Ciencia:

  • Gerontología; Ciencias Cognitivas; Psicología

Sus antecedentes:

  • La evaluación ecológica momentánea (EMA) rastrea las preocupaciones cognitivas subjetivas (PCC) en tiempo real.
  • Las PCC predicen el deterioro cognitivo futuro, pero sus fluctuaciones diarias no se comprenden bien.
  • La EMA basada en teléfonos inteligentes puede evaluar factores transitorios que influyen en las PCC en adultos mayores.

Objetivo del estudio:

  • Investigar la influencia de los factores contextuales diarios en las PCC en adultos mayores que viven en la comunidad.
  • Explorar las asociaciones en tiempo real entre las experiencias diarias y las dificultades cognitivas autoperceptivas.
  • Comprender las relaciones momento a momento entre la vida diaria y las PCC.

Principales métodos:

  • EMA de 14 días basada en teléfonos inteligentes con 6 encuestas diarias.
  • Se evaluaron los lapsos cognitivos diarios, la dificultad para mantenerse despierto, el estrés, el disfrute, la ansiedad y la soledad.
  • Se analizaron las asociaciones mediante modelos lineales mixtos, ajustando por datos demográficos y estado cognitivo.

Principales resultados:

  • 310 adultos mayores participaron, con un promedio de 11.40 días de diario.
  • La dificultad para mantenerse despierto, el estrés, la soledad y la ansiedad se asociaron positivamente con las PCC.
  • La dificultad para mantenerse despierto y la ansiedad se mantuvieron independientemente asociadas con las PCC en el análisis multivariable.

Conclusiones:

  • El estrés diario, las emociones y la vigilia se asocian con las preocupaciones cognitivas subjetivas.
  • Se deben considerar las variables contextuales al utilizar las PCC para la detección de deterioro cognitivo.
  • La investigación futura explorará las vulnerabilidades individuales a los factores contextuales en la predicción del deterioro cognitivo.
