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? What are the main findings?
Response: The Task Force reviewed the latest available evidence to evaluate whether screening all children and adolescents who are 20 years old or younger for high cholesterol improves their heart health into adulthood.
At this time, there is not enough evidence to determine whether or not screening all kids is beneficial, so we are calling for additional research on the effectiveness of screening and treatment of high cholesterol in kids and teens.

MedicalResearch.com: What is the background for this study?
Response: A growing body of evidence links the gut microbiome to brain and immune functioning, and changes to that community of microorganisms is likely among the ways that hardship affects children’s socioemotional development.
Limited evidence in humans has demonstrated the adversities experienced prenatally and during early life influence the composition of the gut microbiome, but no studies had examined whether stress experienced in a mother's own childhood could influence the microbiome of the next generation of children.

MedicalResearch.com: What is the background for this study?
Response: Delivery-related mortality in U.S. hospitals has decreased for all racial and ethnic groups, age groups, and modes of delivery while the prevalence of severe maternal mortality (SMM) increased for all patients, with higher rates for racial and ethnic minority patients of any age.
This study specifically looked at inpatient delivery-related outcomes and found a 57% decrease from 2008-2021. The decreasing mortality rates within the inpatient delivery setting demonstrated as statistically significant and a welcome finding for all women.
This study also looked with greater granularity at the impact of race, ethnicity, and age. Mortality for American Indian women decreased 92%, Asian women decreased 73%, Black women decreased 76%, Hispanic women decreased 60%, Pacific Islander women decreased 79%, and White women decreased 40% during the study period.

MedicalResearch.com: What is the background for this study?
Response: Adolescent cannabis use is increasing in the United States. Prior research suggests that people who start using cannabis earlier are more likely to engage in problematic use and also experience greater mental health challenges and socioeconomic disadvantages overall. For example, children who begin using cannabis early are more likely to have behavioral problems and disorders and are more less likely to complete school.
In our study, we used data from the Adolescent Brain Cognitive Development (ABCD) Study, which is following nearly 12,000 kids across the nation to track behavior and brain development as well as health from middle childhood to young adulthood. We looked at what factors are associated with the initiation of cannabis use by age 12-14.

MedicalResearch.com: What is the background for this study?
Response:Transcatheter left atrial appendageal closure (LAAC) has become an established therapeutic approach for prevention of stroke in subjects with non-valvular atrial fibrillation who are ineligible for long-term oral anticoagulation. Device-related thrombus (DRT), developing after LAAO procedures occurs in a small proportion but patients receiving these devices but is associated with critical embolic events such as ischemic stroke. Thrombogenicity and delayed endothelialization of fabric play a role in the development of DRT. Fluorinated polymers are known to have thromboresistant properties which may favorably modify blood biomaterial interactions of a LAAO device.
In this study we compared the thrombogenicity and endothelial coverage (EC) after left atrial appendage occlusion (LAAO) between a novel fluoropolymer-coated Watchman (FP-WM (Watchman FLX PRO) and the conventional uncoated Watchman FLX (WM).

MedicalResearch.com: What is the background for this study? How does Roflumilast differ from other treatments for seb derm?
Response: Seborrheic dermatitis affects up to 5% of the population globally and can have major impacts on quality of life. Treatment regimens are often complicated given the association of seborrheic dermatitis to hair bearing areas of the body, requiring multiple treatments for different parts of the body. Our phase 2 study aimed to understand the efficacy and safety of once-daily roflumilast foam 0.3% in adults with seborrheic dermatitis on their scalp, face and trunk. Roflumilast foam is a selective and highly potent phosphodiesterase (PDE) 4 inhibition that is being studied for a range of inflammatory skin conditions.
