MedicalResearch.com: What is the background for this study? What is Lecanemab used for? How is it given to patients?
Response: Lecanemab is a new infusion therapy for Alzheimer's disease. Its dosing is based on each patient's body weight (10 mg/kg every two weeks), but the drug is only available in 500 mg and 200 mg single-use vials, meaning that any leftover drug in vials must be thrown away. Given that lecanemab is expected to cost Medicare billions of dollars each year, we hypothesized that discarded drug could result in significant wasteful spending.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Accurate BP measurement is key to identification and treatment of hypertension which serves ultimately to prevent cardiovascular disease. Our study describes substantial measurement error that can occur in a common office and home BP measurement scenario: use of a regular cuff size for all individuals regardless of arm size. Many office triage measurements occur without individualized cuff selection and most home BP devices come with one cuff size – and our study shows that using a regular cuff size for people who have larger arms – those who require a large adult cuff or an extra-large adult cuff – can lead to blood pressure readings that are almost 5 and 20 mmHg greater than their actual BP, respectively. Those require a small adult cuff can have BP readings that are almost 4 mmHg lower than their actual BP.

MedicalResearch.com: What is the background for this study?
Response: While it is well-recognized that survivors of critical illness often experience persistent problems with mental, cognitive, and physical health, very little is known about how these problems (collectively known as post-intensive care syndrome (PICS)) affect resumption of meaningful activities, such as driving.

MedicalResearch.com: What is the background for this study?
Response: Prostate cancer is an important source of morbidity and mortality among men. Earlier detection of disease is essential to reduce these adverse outcomes. Prostate cancer is heritable, and many single nucleotide polymorphisms (SNPs) associated with disease risk have been identified. Thus, there is considerable interest in using tools such as polygenic risk scores, which measure the burden of genetic risk variants an individual carries, to identify men at elevated risk of disease.

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.

MedicalResearch.com: What is the background for this study?
Response: During the initial COVID-19 vaccine campaign with healthcare workers in December 2020, there was an unexpected higher than anticipated rate of immediate allergic reactions after Pfizer and Moderna mRNA vaccines. This prompted both patient and provider concerns, particularly in those with underlying allergic histories, on the associated risks for immediate allergic reactions with the mRNA vaccines.
Because of the significantly improved effectiveness of two doses of an mRNA vaccine compared to one dose, it was important to determine if those who experienced immediate allergic reaction symptoms after their first dose could go on to tolerate a second dose safely.
