MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Emerging adulthood is a unique period of development that ultimately leads to the formation of adult identity, but how this stage contributes to obesity is relatively understudied. The prevalence of obesity has been increasing in the United States population as a whole, and we wanted to know how mean body mass index and the prevalence of obesity have changed over the past several decades specifically among emerging adults. We found that among emerging adults aged 18 through 25, mean BMI has increased from 23.1 kg/m2 in 1976-1980 to 27.7 kg/m2 in 2017-2018. In the same period, the prevalence of obesity increased from 6.2% to 32.7%.

MedicalResearch.com: What is the background for this study?
Response: As a research institute of Leumit, one of the four state mandated health funds in Israel, we pursue research projects aimed at improving the health of our members, and reducing the burden of disease. For this purpose, we harness the unique resource of the electronic health records of our members, that is available in a central data warehouse for research purposes.
Israel was one of the first countries to roll-out a large-scale vaccination campaign, and to achieve control of the pandemics through vaccination. Nevertheless, since the middle of June '21, we have observed a gradual increase in the rate of COVID-19 infections among our members, even among the vaccinated. This increase was first believed to be due to the emergence of the delta strain, but when we compared vaccinated individuals who suffered from breakthrough infections to other vaccinated individuals, we found that the time that has elapsed since vaccination was significantly longer for individuals who got infected with COVID-19, in each of the age groups.
This prompted us to investigate the issue of a possible waning effect of the vaccine protection with time, that we present in this report, using the test negative study design.
We examined the electronic health records for 80,057 adults (average age 44 years) who received a PCR test at least three weeks after their second injection, and had no evidence of previous covid-19 infection. Of these 80,057 participants, 7,973 (9.6%) had a positive test result. These individuals were then matched to negative controls of the same age and ethnic group who were tested in the same week.

MedicalResearch.com: What is the background for this study? What are the main findings?
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: Drug and alcohol related mortality has been on the rise in the US for the past decade, which has drawn a lot of focus from researchers. At the same time maternal mortality, deaths caused by pregnancy complications, is recognized to be higher in the US than in other developed nations.
Very little has been reported about deaths among pregnant and recently pregnant women that are not caused by pregnancy complications, so my collaborators and I wanted to explore this. We did not anticipate that drug and alcohol deaths and homicides would account for so many deaths among pregnant and recently pregnant women.

MedicalResearch.com: What is the background for this study?
Response: Lyme disease presents first on the skin with the classic “bull’s-eye” rash. But such rashes in Black patients aren’t well-represented in medical textbooks. This may lead to physicians not recognizing such rashes in Black patients.
As a result, Black patients are more likely to present with later complications of Lyme disease when first diagnosed such as neurologic complications.

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.
