Chronic Kidney Disease II: Clinical Manifestations

516
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

295
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

358
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

430
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...

Gastroesophageal Reflux Disease II: Clinical Features and Management

647
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

433
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...

Resumen
Este resumen es generado por máquina.

El entrenamiento cognitivo computarizado (CCT) no mostró beneficios a corto plazo para el deterioro cognitivo en adultos mayores. La alta adherencia sugiere que el CCT puede ser valioso a largo plazo o en combinación con otras intervenciones.

Área de la Ciencia:

  • Neurociencia; Gerontología; Psicología Cognitiva

Sus antecedentes:

  • El deterioro cognitivo subjetivo (SCD) y el deterioro cognitivo leve (MCI) predicen la enfermedad de Alzheimer.; El entrenamiento cognitivo computarizado (CCT) es una intervención no farmacológica potencial.; Estudios previos de CCT muestran resultados mixtos y desafíos de adherencia.

Objetivo del estudio:

  • Evaluar la efectividad del CCT en personas con SCD/MCI.; Comparar el CCT con grupos de control activo y de lista de espera.; Evaluar biomarcadores neurofisiológicos y basados en sangre.

Principales métodos:

  • Ensayo controlado aleatorizado (ECA) bicéntrico con 155 participantes (edad media 72.2).; Tres brazos: CCT, control activo (documentales), control de lista de espera.; Intervención de tres meses con 60 sesiones, seguida de 6 meses de CCT para el grupo de intervención.

Principales resultados:

  • No hubo una interacción significativa entre grupos y momentos en cuanto a los resultados cognitivos.; Se observó una alta adherencia (4.87 sesiones/semana) en todos los grupos.; No se observaron cambios en el volumen de materia gris ni en los niveles de amiloide; se notaron mejoras subjetivas después del entrenamiento a largo plazo.

Conclusiones:

  • El CCT de tres meses no mostró ventajas cognitivas o biológicas específicas.; La alta adherencia indica la importancia de intervenciones personalizadas y relevantes.; El CCT a largo plazo mostró efectos subjetivos positivos, lo que sugiere su papel en intervenciones multicomponentes.
