MedicalResearch.com: What is the background for this study?
Response: The impact of the nationwide overdose epidemic on Black women has received little attention from policy-makers, researchers, or the press.
MedicalResearch.com: What are the main findings?
Response: Over the 7-year study period, preventable overdose deaths among Black women resulted in nearly 0.75 million years of life lost (YLL). Women aged 25-34 have suffered a rising proportion of this burden.

Response: We started many years ago by studying some natural and synthetic molecules that were able to counteract the early stages of this disease. With a view to early prevention, we wondered if these molecules could be routinely taken with the diet or dietary supplements. So our studies focused on the search for bioactive molecules present in food and edible plants.
Hops are very rich in polyphenolic compounds, and for this reason it is historically used for the production of beer, but also for the preparation of herbal teas and infusions, and its uses in traditional medicine are known. In recent years we have also collected interesting results on Coffee, Sage, Radix Imperatoriae, Cocoa and Cinnamon extracts.

Response: Service dogs for PTSD are becoming more common and the evidence shows they can help improve mental health and quality of life for many veterans with PTSD. However, some veterans benefit more than others. Our research goal was to ask for the very first time: Why?

Response: The link between playing American football at the professional level and later-life brain disorders like chronic traumatic encephalopathy – or CTE -- and ALS has received increasing attention over the past 15 years. Previous research has shown that former NFL players are more likely to die from CTE and amyotrophic lateral sclerosis (ALS) and more likely to report cognitive impairment, behavioral changes, and dementia during life. Despite previous research focusing on the later-life effects of playing American football at the professional level, the long-term effects of college football participation remain largely unknown.
We had two goals for this new investigation. The first was to conduct a survey of the current overall health status, including cognitive and other neurological disorders, of older former college American football players compared with men in the general population. The second goal was to examine the mortality rate and causes of death in a cohort of older former college football players. The target population for this study was all 447 former Notre Dame football players who were listed as seniors on the varsity rosters during the 1964-1980 seasons. This was the era of legendary coaches Ara Parseghian and Dan Devine. I should add that this study was fully independent of the University of Notre Dame.

Response: Identifying early risk factors and early changes in the brain will have a major impact on future clinical and public health priorities related to the looming epidemic of dementia. Several studies based on older populations suggest mid-life is an important period to start prevention measures. To date control of blood pressure levels has been the most robust and promising candidate to target for prevention of future cognitive impairment. Although several studies have looked at levels of blood pressure and risk for cognitive impairment, it was not known whether trajectories from young adulthood to middle age studies provided additional information about risk. To investigate possible biomarkers of future risk, we chose to examine the association of the mean arterial blood pressure trajectories to indicators of pathology seen on MRI and that are associated with cognition.
We highlight the results of the mean arterial blood pressure (MAP) measure, which is an integrated measure of systolic and diastolic blood pressure.

Response: The prescription stimulants methylphenidate, amphetamine, and lisdexamfetamine, classified as Schedule II substances, are sympathomimetic drugs with therapeutic use widely used in the US for Attention Deficit Hyperactivity Disorder. Changes in criteria for diagnosis of Attention Deficit Hyperactivity Disorder in 2013 and approval of lisdexamfetamine for binge eating disorder in 2015 may have impacted usage patterns.
The goal of this study1 was to extend upon past research2 to compare the pharmacoepidemiology of these stimulants in the United States from 2010–2017, including consideration to variation within geographic regions, the Hispanic population, and the Medicaid population.

Response: There is conflicting evidence regarding the association between repetitive head impacts during youth contact sports and worse neurocognitive outcomes. Most research has been conducted in older adults, while the research in children is mostly limited to 1-2 sports seasons.

MedicalResearch.com: What is the background for this study?
Response: Although high systolic blood pressure in midlife has consistently been reported as a condition that increases the risk of developing dementia in old age, reports regarding this relationship in older people have been inconsistent. One potential reason for this, is that the relationship between systolic blood pressure and dementia in later life may be U-shaped, meaning that both individuals with low and with high systolic blood pressure are at increased incident dementia risk.
This study combined data from several longitudinal cohort studies specifically designed to study incident dementia in older people, to investigate whether these U-shaped relationships exist, and in which age ranges they appear. We included more than 16,500 people aged 60 and older, with over 2,700 incident dementia cases.
Also, we aimed to investigate whether these observational associations might be caused by confounding, differences in mortality, or result from opposite relationships between certain subgroups of individuals.

Response: Cataract is a natural aging process of the eye and affects the majority of older adults who are at risk for dementia. Sensory loss, including vision and hearing, is of interest to the research community as a possible risk factor for dementia, and also as a potential point of intervention. Because cataract surgery improves visual function, we hypothesized that older people who undergo cataract surgery may have a decreased risk of developing Alzheimer disease and dementia.
We used the longitudinal data from an ongoing, prospective, community based cohort, Adult Changes in Thought (ACT) study. The ACT study includes over 5000 participants to date who are dementia free at recruitment and followed until they develop Alzheimer disease or dementia. We had access to their extensive medical history including comprehensive ophthalmology visit data. We investigated whether cataract surgery was associated with a decreased risk of developing Alzheimer disease and dementia.

Response: We know that there are multiple medium to long-term risk factors for stroke, as people with conditions such as hypertension (high blood pressure) or diabetes mellitus (high blood glucose levels) and those with risk factors (such as smoking, obesity, poor diet quality and others) are at increased risk of stroke. However, we still find it difficult to predict who will have a stroke.
We were interested in exploring if short-term exposures to anger or emotional upset or a period of heavy physical exertion might lead to, or ‘trigger’ a stroke. We looked at this previously for myocardial infarction (heart attack) in a study called INTERHEART. Some smaller studies have looked at this before, with less people experiencing a stroke and often confined to one country or geographical region. Here, in INTERSTROKE, we included over 13,000 people who had a stroke and asked about the one hour period before the onset of the stroke and also about the same period on the day before.

Response: This study was funded by Singapore’s Ministry of Health Geriatric Education and Research Institute.
We randomly recruited 500+ adults aged 21-90+ from the residential town of Yishun. We performed detailed assessments of physical and cognitive performance, body composition using DEXA, and participants also provided information on their levels and frequencies of physical activities (PA) including recreational PA/exercise, commuting, housework and other occupational related PA. The demographics of the sample of participants is the same as that of Singapore in terms of age and ethnic composition. Comparing the results of those aged 21-<65 and those >=65 years, only around a third (36%; 90) of those in the younger group and only around half (48%;116) of those in the older age group, met guidelines recommended physical activity quota exclusively from recreational PA/exercise. But nearly two thirds (61% younger; 152 and 66% older; 159) met this target exclusively through housework.
