Association Between Aluminum Exposure From Vaccines Before Age 24 Months and Persistent Asthma at Age 24 to 59 Months
ObjectiveTo assess the association between cumulative aluminum exposure from vaccines before age 24 months and persistent asthma at age 24 to 59 months.MethodsA retrospective cohort study was conducted in the Vaccine Safety Datalink (VSD). Vaccination histories were used to calculate cumulative vaccine-associated aluminum in milligrams (mg). The persistent asthma definition required one inpatient or 2 outpatient asthma… Continue reading Association Between Aluminum Exposure From Vaccines Before Age 24 Months and Persistent Asthma at Age 24 to 59 Months
Psychological factors substantially contribute to biological aging: evidence from the aging rate in Chinese older adults
We have developed a deep learning aging clock using blood test data from the China Health and Retirement Longitudinal Study, which has a mean absolute error of 5.68 years. We used the aging clock to demonstrate the connection between the physical and psychological aspects of aging. The clock detects accelerated aging in people with heart,… Continue reading Psychological factors substantially contribute to biological aging: evidence from the aging rate in Chinese older adults
Causal analysis identifies small HDL particles and physical activity as key determinants of longevity of older adults
BackgroundThe hard endpoint of death is one of the most significant outcomes in both clinical practice and research settings. Our goal was to discover direct causes of longevity from medically accessible data.MethodsUsing a framework that combines local causal discovery algorithms with discovery of maximally predictive and compact feature sets (the “Markov boundaries” of the response)… Continue reading Causal analysis identifies small HDL particles and physical activity as key determinants of longevity of older adults
Motion, Relation, and Passion in Brain Physiological and Cognitive Aging
Abstract: The aim of the current paper was to present important factors for keeping the basic structures of a person’s brain function, i.e., the grey and white matter, intact. Several lines of evidence have shown that motion, relation, and passion are central factors for preserving the neural system in the grey and white matter during… Continue reading Motion, Relation, and Passion in Brain Physiological and Cognitive Aging
Linzagolix with and without hormonal add-back therapy for the treatment of symptomatic uterine fibroids: two randomised, placebo-controlled, phase 3 trials
Uterine fibroids are common non-cancerous neoplasm that cause heavy menstrual bleeding and other signs. Linzagolix is an oral gonadotropin-releasing hormone receptor antagonist taken once per day that dose-dependently suppresses gonadal steroids and might reduce uterine-fibroid-associated signs. Two phase 3 trials were conducted to confirm the efficacy and safety of linzagolix at full-suppression (200 mg) and… Continue reading Linzagolix with and without hormonal add-back therapy for the treatment of symptomatic uterine fibroids: two randomised, placebo-controlled, phase 3 trials
Modifiable risk factors and long term risk of type 2 diabetes among individuals with a history of gestational diabetes mellitus: prospective cohort study
Objectives To evaluate the individual and combined associations of five modifiable risk factors with risk of type 2 diabetes among women with a history of gestational diabetes mellitus and examine whether these associations differ by obesity and genetic predisposition to type 2 diabetesSetting Nurses’ Health Study II, US.Participants 4275 women with a history of gestational diabetes mellitus, with… Continue reading Modifiable risk factors and long term risk of type 2 diabetes among individuals with a history of gestational diabetes mellitus: prospective cohort study
Associations of sleep timing and time in bed with dementia and cognitive decline among Chinese older adults: A cohort study
Background: The longitudinal associations of sleep timing and time in bed (TIB) with dementia and cognitive decline in older adults are unclear. Methods: This population-based cohort study used data from 1982 participants who were aged ≥60 years, free of dementia, and living in rural communities in western Shandong, China. At the baseline (2014) and follow-up… Continue reading Associations of sleep timing and time in bed with dementia and cognitive decline among Chinese older adults: A cohort study
Changing Flows Balance Nutrient Absorption and Bacterial Growth along the Gut
Small intestine motility and its ensuing flow of luminal content impact both nutrient absorption and bacterial growth. To explore this interdependence we introduce a biophysical description of intestinal flow and absorption. Rooted in observations of mice we identify the average flow velocity as the key control of absorption efficiency and bacterial growth, independent of the… Continue reading Changing Flows Balance Nutrient Absorption and Bacterial Growth along the Gut
