Dejar de fumar podría mejorar la memoria

Los que fuman tienen más problemas para recordar las tareas, sugiere un pequeño estudio

MIÉRCOLES, 21 de septiembre (HealthDay News) -- Además de los muchos y bien conocidos beneficios de salud de dejar de fumar, los investigadores ahora han descubierto otro buen motivo para abandonar el hábito: podría ayudar a mejorar la memoria cotidiana.

El equipo de la Universidad de Northumbria en Newcastle, Reino Unido, administró pruebas de memoria a 27 fumadores, 18 ex fumadores y 24 personas que nunca habían fumado. En la prueba, tenían que recordar hacer las tareas asignadas en distintos lugares del campus universitario.

Los fumadores apenas recordaron 59 por ciento de las tareas, frente a 74 por ciento en los ex fumadores y 81 por ciento en los que nunca habían fumado.

"Ya sabemos que dejar de fumar tiene inmensos beneficios de salud para el cuerpo, pero este estudio también muestra cómo dejar de fumar puede tener... beneficios para la función cognitiva [del cerebro]", señaló en un comunicado de prensa de la Northumbria el investigador Tom Heffernan, del Grupo de Investigación Colaborativa sobre las Drogas y el Alcohol de la universidad.

Apuntó que este es el primer estudio en examinar el efecto que dejar de fumar tiene sobre la memoria.

"Dado que hay hasta diez millones de fumadores en R.U. y hasta 45 millones en EE. UU., es importante comprender los efectos que fumar tiene sobre la función cognitiva cotidiana, de la cual la memoria prospectiva es un excelente ejemplo", señaló Heffernan.

El estudio se publicó en línea como adelanto de su aparición en una próxima edición impresa de la revista Drug and Alcohol Dependence.

Light Therapy holds promise as a treatment for Alzheimer's Disease

A new article, conducted by Lili Zang and colleagues from Weifang Medical University School of Nursing in Shandong Province, China, discusses a meta-analysis of 15 high-quality trials that investigated the impact of light therapy on individuals with Alzheimer’s disease (AD). The meta-analysis included 598 patients with mild to moderate Alzheimer’s disease, and it covered 15 randomized controlled trials conducted in seven different countries. Those trials were published between 2005 and 2022. Sleep Improvement Light therapy led to significant improvements in several sleep measures. It notably enhanced sleep efficiency, increased interdaily stability, and reduced intradaily variability, all of which are indicators of better sleep quality. Light therapy was associated with a reduction in agitation, depression, and caregiver burden among individuals with Alzheimer’s disease. A significant advantage over usual care was shown in reducing the severity of psychobehavioral symptoms, as assessed

Carvacrol: Health benefits from aromatic herbs (oregano, thyme)

Carvacrol is a phenolic monoterpenoid found in various essential oils. Oregano, thyme, and bergamot contain carvacrol. It boasts a range of beneficial properties for potential clinical applications. This compound has shown antimicrobial, antioxidant, and anticancer activities. It showed antimicrobial efficacy against food-borne pathogens like Escherichia coli and Salmonella. It is attributed to a unique combination of its chemical characteristics. Carvacrol, often used alongside thymol (another phenolic monoterpenoid found in these oils), exhibits high antioxidant activity and has been employed as a dietary additive to enhance the antioxidant status in animals (I.E. in poultry nutrition) Preclinical studies suggest promising anticancer properties of carvacrol, particularly in breast, liver, and lung carcinomas, through (proapoptotic) mechanisms involving elimination of DNA abnormalities. However, despite a well-defined toxicological profile, the lack of human trials hinders conclusive

Creatine for six months can improve long COVID fatigue

A small study suggests that taking creatine as a supplement for six months may significantly improve clinical features of post–COVID-19 fatigue syndrome (long COVID). Those symptoms are: Fatigue Shortness of breath Chest pain Joint pain Cognitive difficulties often referred to as “brain fog.” The study, conducted by researchers from the University of Novi Sad, Serbia, found that creatine supplements led to reduced fatigue and improved scores for various long COVID-related symptoms, such as loss of taste, breathing difficulties, body aches, headaches, and concentration problems. Creatine is a natural compound found in small amounts in certain foods and produced by the body, mainly in muscles. It plays a crucial role in the Adenosine Triphosphate -Phosphocreatine (ATP-PC) energy system, which is the primary source of energy for short bursts of intense activities lasting from 1 to 30 seconds, like weightlifting or sprinting. Supplementing with creatine has been proven to increase the
