#Aspirin for primary prevention of cardiovascular disease, part 2

..ASPREE study suggests no benefit from aspirin in primary prevention ASPREE randomized 19,114 healthy people 70 or over (65 or over for African Americans and Hispanics) to receive either 100 milligrams of enteric-coated aspirin or placebo. After an average of almost five years, there was no significant difference in the rate of fatal coronary heart disease, heart attack, stroke, or hospitalization for heart failure. There … Continue reading #Aspirin for primary prevention of cardiovascular disease, part 2

BrainAGE and regional volumetric analysis of a Buddhist monk: a longitudinal MRI case study

Yongey Mingyur Rinpoche (YMR) is a Tibetan Buddhist monk, and renowned meditation practitioner and teacher who has spent an extraordinary number of hours of his life meditating. The brain-aging profile of this expert meditator in comparison to a control population was examined using a machine learning framework, which estimates “brain-age” from brain imaging. YMR’s brain-aging rate appeared slower than that of controls suggesting early maturation … Continue reading BrainAGE and regional volumetric analysis of a Buddhist monk: a longitudinal MRI case study

#Diet modulates brain network stability, a biomarker for brain #aging, in young adults

..One cohort was scanned under standard diet, overnight fasting, and ketogenic diet conditions. To isolate the impact of fuel type, an independent overnight fasted cohort was scanned before and after administration of a calorie-matched glucose and exogenous ketone ester (D-β-hydroxybutyrate) bolus. Across the life span, brain network destabilization correlated with decreased brain activity and cognitive acuity. Effects emerged at 47 y, with the most rapid … Continue reading #Diet modulates brain network stability, a biomarker for brain #aging, in young adults

#Vegetarian diet and incidence of total, ischemic, and hemorrhagic #stroke in 2 cohorts in Taiwan

To determine how a vegetarian diet affects stroke incidence in 2 prospective cohorts and to explore whether the association is modified by dietary vitamin B12 intake.. ..Vegetarians had lower serum vitamin B12 and higher folate and homocysteine than nonvegetarians. In cohort 1, 54 events occurred in 30,797 person-years follow-up. Vegetarians (vs nonvegetarians) experienced lower risk of ischemic stroke (hazard ratio [HR], 0.26; 95% confidence interval … Continue reading #Vegetarian diet and incidence of total, ischemic, and hemorrhagic #stroke in 2 cohorts in Taiwan

Practice guideline: Treatment for insomnia and disrupted sleep behavior in children and adolescents with autism spectrum disorder

Major recommendations (Level B) For children and adolescents with ASD and sleep disturbance, clinicians should assess for medications and coexisting conditions that could contribute to the sleep disturbance and should address identified issues. Clinicians should counsel parents regarding strategies for improved sleep habits with behavioral strategies as a first-line treatment approach for sleep disturbance either alone or in combination with pharmacologic or nutraceutical approaches. Clinicians … Continue reading Practice guideline: Treatment for insomnia and disrupted sleep behavior in children and adolescents with autism spectrum disorder

The associations of major #foods and fibre with risks of ischaemic and haemorrhagic #stroke: a prospective study of 418 329 participants in the EPIC cohort across nine European countries

..For ischaemic stroke (4281 cases), lower risks were observed with higher consumption of fruit and vegetables combined (HR; 95% CI per 200 g/day higher intake, 0.87; 0.82–0.93, P-trend < 0.001), dietary fibre (per 10 g/day, 0.77; 0.69–0.86, P-trend < 0.001), milk (per 200 g/day, 0.95; 0.91–0.99, P-trend = 0.02), yogurt (per 100 g/day, 0.91; 0.85–0.97, P-trend = 0.004), and cheese (per 30 g/day, 0.88; 0.81–0.97, P-trend = 0.008), while higher risk was observed with higher red meat consumption which attenuated … Continue reading The associations of major #foods and fibre with risks of ischaemic and haemorrhagic #stroke: a prospective study of 418 329 participants in the EPIC cohort across nine European countries

Association of Dual Decline in Memory and #Gait Speed With Risk for #Dementia Among Adults Older Than 60 Years

Dual decline in both memory and gait speed may characterize a group of older individuals at high risk for future dementia.. ..Participants were 60 years or older, had an initial gait speed of more than 0.6 m/s (ie, free of overt dismobility), with repeated measures of memory and gait speed before dementia diagnosis during a mean follow-up of 6.6 to 14.5 years. Within each study, … Continue reading Association of Dual Decline in Memory and #Gait Speed With Risk for #Dementia Among Adults Older Than 60 Years

The association between actor/partner #optimism and #cognitive functioning among older couples

Higher optimism has been linked with health, well‐being, and cognitive functioning. Spouses also play an important role on people’s health, especially in older adulthood.. ..Optimism was assessed at baseline (t1) and cognition was measured every two years with up to five repeated assessments of cognition data over the 8‐year follow‐up period (t1; t2; t3; t4; t5). Results Results from multi‐level dyadic data analyses showed small … Continue reading The association between actor/partner #optimism and #cognitive functioning among older couples

Body #height in young adult men and risk of #dementia later in adult life

… A total of 666,333 men, 70,608 brothers, and 7388 twin brothers born 1939–1959 and examined at the conscript board were followed in Danish nationwide registers (1969–2016). Cox regression models were applied to analyze the association between body height and dementia. Within-brothers and within-twin pair analyses were conducted to explore the role of shared familial factors including partly shared genetics. In total, 10,599 men were … Continue reading Body #height in young adult men and risk of #dementia later in adult life

How #odor cues help to optimize #learning during sleep in a real life-setting

Effortless learning during sleep is everybody’s dream. Several studies found that presenting odor cues during learning and selectively during slow wave sleep increases learning success.. ..We (1) performed a field study of vocabulary-learning in a regular school setting, (2) stimulated with odor cues during the whole night without sleep monitoring, and (3) applied the odor additionally as retrieval cue in a subsequent test.. ..Our results … Continue reading How #odor cues help to optimize #learning during sleep in a real life-setting
