Los fumadores jóvenes podrían ser más propensos a probar la marihuana

Un estudio halla que los problemas de comportamiento predicen menos el uso de marihuana en el futuro

Robert Preidt. MARTES, 26 de enero (HealthDay News/DrTango) -- Fumar cigarrillos, y no los problemas de comportamiento, predicen de forma independiente y consistente el uso de marihuana entre los adolescentes, de acuerdo con un nuevo estudio.
El hallazgo procede de un estudio de más de 1,600 jóvenes holandeses que fueron evaluados a la edad de 10 a 12 años y de nuevo de los 12 a los 15 y de los 15 a los 18 años.
Los resultados mostraron que la relación entre lo que los investigadores calificaron como problemas de comportamiento externos, es decir conducta, déficit de atención/hiperactividad y oposición, y el uso de marihuana no era consistente. Sin embargo, se encontró que fumar cigarrillos a una edad temprana predecía el uso futuro de marihuana.
Los hallazgos, publicados en la edición de enero de la revista Journal of the American Academy of Child and Adolescent Psychiatry, desafían la creencia generalizada de que los problemas de conducta predicen de forma directa el uso de marihuana.
"Fumar cigarrillo a una edad temprana es un potente factor de predicción del uso futuro de marihuana, independientemente de los problemas de comportamiento externos", escribieron los investigadores. "Aunque los problemas de comportamiento externos son importantes como punto de inicio de la trayectoria del uso de sustancias, fumar a una edad temprana se podría identificar como un marcador importante del riesgo de uso de marihuana".

Brain health. Promising prebiotics and probiotics combination

According to new research, the bacteria in our gut, known as gut microbiota, play an important role in brain injury and healing after a stroke. Taking particular types of prebiotics and probiotics can help with brain injury, inflammation, gut bacteria imbalances, and intestinal health. However, we still don't know whether prebiotics, probiotics, or synbiotics (a combination of both) perform best for particular conditions, or how they operate. In this study, scientists tested a new synbiotic formulation containing multiple strains of probiotics Lactobacillus reuteri UBLRu-87 Lactobacillus plantarum UBLP-40 Lactobacillus rhamnosus UBLR-58 Lactobacillus salivarius UBLS-22 Bifidobacterium breve UBBr-01 and prebiotic fructooligosaccharides (FOS) FOS are extracted from the blue agave plant and fruits and vegetables such as bananas, onions, chicory root, garlic, asparagus, jícama, and leeks. Some grains and cereals, such as wheat and barley, also contain FOS. The Jerusalem artichoke and ...

Sweetener Reformulated Biscuits: A Step Towards Blood Glucose Control

In a recent study led by Catherine Gibbons from the University of Leeds, the effects of sweetener reformulated biscuits on appetite and endocrine responses in adults with overweight or obesity were evaluated. This study, conducted between 2021 and 2022 in England and France, sheds light on the potential benefits of substituting sucrose with sweeteners like neotame and stevia rebaudioside M (StRebM). The findings suggest that while the reformulated biscuits yielded similar appetite responses compared to sucrose-sweetened ones, they demonstrated a significant advantage in terms of post-meal insulin and glucose levels. Participants consuming biscuits with neotame and StRebM experienced lower postprandial insulin levels compared to those consuming sucrose, indicating a potential positive impact on blood glucose control. This is particularly noteworthy in the context of individuals at risk of developing type 2 diabetes. However, it's essential to acknowledge the limitations highlighted ...
