Response: Medicare is the US public insurance program mainly serving people 65 years and older, but also some younger adults who have long-term disabling conditions. As such, on average, the Medicare population bears a heavy burden of illness and has high health care needs, compared to the general US population. The under-65 group for the most part has quite low incomes, while the older group represents a wide spectrum, from poor to well-off. Medicare beneficiaries also differ a great deal in terms of whether they have access to supplemental insurance that can help with patient cost-sharing requirements. I’m referring to Medicaid assistance, or a self-purchased Medigap plan, or retiree health benefits, etc. The cost-sharing requirements in traditional Medicare are substantial — e.g., 20% for doctor visits — and there is no annual cap on patient out-of-pocket spending. That’s in contrast to commercial insurance and Medicare Advantage managed care plans — all of those have an annual cap on patient out-of-pocket costs.
There’s a good amount of existing research on whether people in Medicare can afford their drugs, and on the affordability of medical care among younger groups such as working-aged uninsured people and those in ACA exchange plans. But there hasn’t been much research into medical care affordability among older Americans.

MedicalResearch.com: What is the background for this study and recommendation statement?
Response: Dental caries, also known as cavities or tooth decay, is the most common chronic disease in children in the United States and can develop in any child whose teeth have come in. Many young children under five years old do not visit a dentist, so the Task Force reviewed the latest evidence on how primary care clinicians can help prevent tooth decay in young children.
The Task Force’s research led to two important findings: all young children whose teeth have come in should have fluoride varnish applied by their clinician, and all children six months and older whose water supply doesn’t contain enough fluoride should receive fluoride supplements. Both approaches can help prevent cavities in kids.
The Task Force also determined that there is not enough evidence to recommend for or against screening for tooth decay in the primary care setting for children under five. This is consistent with the Task Force’s 2014 recommendation on dental caries.

MedicalResearch.com: What is the background for this study?
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: Early randomized trials showed that the BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) vaccines were both remarkably effective at preventing symptomatic disease, when comparing each vaccine with no vaccine. However, head-to-head comparisons of these vaccines have been lacking, leaving open the question of which vaccine is more effective.
In this study, we analyzed the VA’s high-quality databases in a way that emulated the design of the hypothetical trial that would have answered this question. Specifically, we used the findings from the original trials to benchmark our methods and then extended them to provide novel evidence for the comparative effectiveness of these two vaccines in a real-world setting and across diverse subgroups and different time periods.

MedicalResearch.com: What is the background for this study?
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.

Response: We found that the rates of TAVR were lower in areas with higher proportions of Black, Hispanic and socioeconomically disadvantaged patients. Inequities in access in areas with higher proportions of Black and Hispanic patients existed despite adjusting for socioeconomic status.

MedicalResearch.com: What is the background for this study?
Response: The VA operates a very robust, embedded quality improvement and implementation science program, of which our team is involved. As the VA was one of the first US healthcare systems to rollout COVID-19 vaccination programs, we were asked to evaluate these efforts in real-time, to provide input to VA healthcare leaders on what was going well and what could be improved. This survey reported in JAMA Network Open is one of the quality improvement efforts we engaged in.

MedicalResearch.com: What is the background for this study?
Response: We decided to review the evidence for zinc in response to calls for rapid evidence reviews to inform self-care and clinical practice during the COVID-19 pandemic.
Laboratory studies have found that zinc can inhibit the replication of many respiratory viruses, including SARS-CoV-2 and other coronaviruses. Zinc plays a key role in immunity, inflammation, tissue injury, ACE-2 receptor activity, and also in tissue responses to a lack of oxygen. Low zinc status may be a risk factor for severe SARS-CoV-2 illness.
Additionally, there was some indirect evidence suggesting zinc might be effective for other respiratory tract infections such as the common cold and we wanted to verify this.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Preeclampsia is one of the most serious health problems that can occur during pregnancy. It can lead to preterm birth, and in some cases even death of the pregnant person and their baby.
The Task Force looked at the latest available evidence and found that low-dose aspirin can help prevent preeclampsia in pregnant people who are at highest risk, and it can also protect their babies. This new final recommendation is consistent with the Task Force’s 2014 recommendation statement and has the potential to save many lives.

MedicalResearch.com: What is the background for this study?
Response: Medications are generally safe when used as prescribed or as directed on the label, but there can be risks in taking any medication. Adverse drug events are harms resulting from the use of medication.
The risk of adverse drug events is highest among older adults and very young children. Older adults have higher risks because they typically take more medications and are more likely to have underlying medical conditions. Very young children have higher risks because they often find and ingest medications meant for others.
Previous studies of medication safety have focused on harm from medications when taken for therapeutic reasons. Separate studies have focused on harm from specific types of non-therapeutic use (taking medications for recreational use or self-harm). This study examined the number of emergency department (ED) visits that resulted when people who took medications for any reason – as directed by a clinician or for other reasons, including recreational use or intentional self-harm.
