Response: An unusually low number of extremely preterm births have been observed in some countries during the initial covid-19 lockdowns. We speculated that this could be because of fewer infections, reduced activity levels, less stress etc. These are also factors that change with the seasons, and we hypothesized that extremely preterm birth might be associated with seasonality.

Response: Canada legalized recreational, or non-medical, cannabis in October 2018. Canada took phased approach to legalization initially only allowing flower-based cannabis products and oils and after one year permitting the sale of commercial cannabis edibles (e.g. THC containing candies, baked goods, and drinks). In this study we took advantage of this phased roll out of legal cannabis to understand the impact of legalization on cannabis exposures or poisonings in children aged 0-9 years and the contribution of different types of cannabis products to these events.

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: Racial inequities are pervasive in our country, and cardiovascular therapeutics with proven benefit have been shown to be underutilized among Black and Latinx patients.
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), a recommended treatment option for glycemic control in patients with diabetes, have recently emerged as a cardioprotective therapy as multiple large randomized clinical trials have shown they prevent cardiovascular events among patients with Type 2 Diabetes (T2D), particularly patients with established atherosclerotic cardiovascular disease (ASCVD). Given this, they are now recommended therapy for patients with diabetes and established or high risk of ASCVD.
Given the known inequitable utilization of other therapies, along with the known higher burden of diabetes and cardiovascular disease among Black patients, the aim of this study was to evaluate the uptake of GLP-1 RA as well as for inequities in utilization.

Response: A majority of people on dialysis who completed vaccination as of September 2021 have had a decline in antibody response to levels that would render them vulnerable to infection. Antibody response immediately after vaccination and circulating antibody response is strongly associated with risk for breakthrough after the initial vaccination series.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Sickle cell disease is caused by a point mutation in the beta-globin gene of hemoglobin resulting in the production of abnormal hemoglobin which leads to formation of sickle-shaped RBC under conditions of low oxygen. Sickle cell disease affects about 100,000 patients in the US which are predominantly African American. The only curative approach is to perform an allogeneic bone marrow transplant which is however fraught with significant treatment-related risks if a matched sibling donor is not available.
The current study describes the successful application of a novel gene therapy to treat patients with sickle cell disease. The strategy is based on a gene-addition approach to introduce the genetic information for a Hemoglobin F-like molecule termed HgAT87Q into hematopoietic stem cells. The expression of this novel hemoglobin prevents polymerization of HgbS and has now been demonstrated to prevent the occurrence of vaso-occlusive pain crises in sickle cell disease patients.

Response: About 1.8 million Americans are currently incarcerated, more than any other country in the world per capita. Of those 1.8 million, about 1 in 7 suffers from opioid addiction, putting them at high risk of overdose and death, particularly in the weeks following release.
Opioid use disorder is a treatable condition, particularly with the medications buprenorphine or methadone, but historically, prisons and jails have not offered treatment. Over the past five years, a few states and municipalities have enacted policies to provide access for OUD treatment. We examined whether these policies were actually improving access to treatment.

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.
