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 its relative yacón, together with the blue agave plant, have been found to have the highest concentrations of FOS of cultured plants. (See more)

They used a rat model of stroke called middle cerebral artery occlusion (MCAO).

Before producing a stroke, they gave the synbiotic to the rats for three weeks.

Three days after the stroke, the rats' sensory and motor abilities improved by the synbiotic treatment.

It halted the death of brain cells in the damaged area and
Diminished the extent of the stroke's brain damage.

The synbiotic therapy also

Restored the levels of proteins that support intestinal integrity
Reversed the elevated amounts of certain proteins and chemicals linked to brain inflammation and cell death.
Increased the abundance of good bacteria
Reduced harmful bacteria

Rats, not human beings, but these findings suggest that the new synbiotic preparation has the potential to improve neurological dysfunctions caused by stroke by influencing the communication between the gut and the brain in rats.

Exploring the Link Between Circadian Rhythms, Longevity, and Wearable Data: Insights and Future Directions

A recent study in NHANES 2011–2014 explores the potential connection between disruptions in circadian rhythms, measured using wearable devices, and their impact on health outcomes and longevity. The study analyzes data from 7,297 U.S. adults collected through wearable accelerometers as a novel digital biomarker for longevity. Five distinct clusters were identified based on activity profiles: "High activity," "Low activity," "Mild circadian rhythm (CR) disruption," "Severe CR disruption," and "Very low activity." The findings reveal that young adults with extreme circadian rhythm disturbance exhibit higher white blood cell counts and accelerated biological aging. Older adults with circadian disruption are associated with increased systemic inflammation indexes, advanced biological aging, and higher all-cause mortality risk. The research underscores the importance of circadian alignment for longevity at all ages and suggests that wearable

The safety of aspartame is under review by WHO after conflicting findings.

Aspartame, a sweetener with health effects Since 1981, the WHO expert committee on additives has confirmed the safety of aspartame consumption within acceptable daily limits. The international organization has established that the acceptable daily intake (ADI) of aspartame is 40 milligrams per kilogram of body weight. This means that a person can consume up to 40 mg of aspartame per kilogram of their body weight per day without risking their health. For example, if someone weighs 60 kilos, the allowable amount of aspartame would be 2,400 milligrams (40 mg/kg x 60 kg). In recent years, several studies have been carried out on the effects of aspartame on health. The Food and Drug Administration (FDA) has reviewed the scientific evidence related to the safety of this sweetener five times since its approval in 1981, and has concluded that it remains safe for use. However, it is being studied again. It has an especially important use in low-calorie beverages consumed by children and pregnan

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
