Resumen
El aumento de la actividad física puede reducir la mortalidad en las mujeres mayores. Mantener o aumentar los niveles de ejercicio puede prolongar la vida, especialmente para aquellos que no son consistentemente activos.
Área de la Ciencia:
- Gerontología Gerontología.
- Salud Pública La salud pública.
- Epidemiología La epidemiología.
Sus antecedentes:
- La actividad física está relacionada con la reducción de la mortalidad.
- El impacto de los cambios en la actividad física en la mortalidad en las mujeres mayores sigue sin estar claro.
Objetivo del estudio:
- Investigar la asociación entre los cambios en la actividad física y las tasas de mortalidad en mujeres mayores.
- Para determinar si el aumento o disminución de la actividad física influye en la longevidad en este grupo demográfico.
Principales métodos:
- Estudio de cohorte prospectivo en el que participaron 9518 mujeres mayores de 65 años en 4 centros de EE.UU.
- La actividad física evaluada en el inicio y el seguimiento; la mortalidad rastreada hasta 12,5 años.
- El estado vital y las causas de la muerte se confirmaron a través de certificados de defunción y resúmenes de alta.
Principales resultados:
- Las mujeres que aumentaron la actividad física mostraron una mortalidad por todas las causas, enfermedades cardiovasculares y cáncer significativamente menor en comparación con las personas sedentarias.
- Estos beneficios persistieron independientemente del estado de la enfermedad crónica, pero fueron menos pronunciados en mujeres mayores de 75 años o con mala salud.
- La actividad física constante en ambos puntos de evaluación también se correlacionó con una reducción de la mortalidad por todas las causas y cardiovascular.
Conclusiones:
- Aumentar y mantener la actividad física puede extender la esperanza de vida en las mujeres mayores.
- Los beneficios son potencialmente reducidos para las mujeres de 75 años o más o aquellas con peor salud.

01:24Nephrotic Syndrome I : Introduction
476
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

01:15Glomerular Filtration
4.7K
The filtration membrane in the renal system is a highly specialized structure essential for filtering blood. It consists of glomerular capillaries and podocytes, forming a selective barrier that permits the passage of water and small solutes while restricting most plasma proteins and blood cells.
Components of the Filtration Membrane
The filtration process involves three key layers: the glomerular endothelial cells, the basement membrane, and the podocyte-formed filtration slits.

6.9K
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

19.9K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

01:10Nephrons
6.3K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

01:28Glomerular Filtration Rate and its Regulation
5.0K
The Glomerular Filtration Rate (GFR) is a measure of kidney function, reflecting the volume of filtrate formed per minute in the kidneys. On average, GFR is approximately 125 mL/min in males and 105 mL/min in females. Maintaining a relatively constant GFR is essential for the kidneys to effectively regulate body fluid homeostasis and maintain extracellular stability.
GFR regulation involves two primary intrinsic controls: the myogenic and tubuloglomerular feedback mechanisms.
