Outcomes of Older Adults and Frail Patients Receiving Idecabtagene Vicleucel: A CIBMTR Study.

Idecabtagene vicleucel (ide-cel) is an anti-BCMA CAR-T cell therapy approved for patients with relapsed/refractory multiple myeloma (RRMM) after 2 prior lines of therapy. There is limited data on outcomes of CAR T in older adults and frail patients with RRMM. In this study, we utilized data from the Center for International Blood and Marrow Transplantation Registry to describe the safety and efficacy of ide-cel in these clinically important subgroups.

Identification of Factors Influencing Donor-Derived Cell-Free DNA Levels up to One Year After Kidney Transplant.

Donor-derived cell-free DNA (dd-cfDNA) in the peripheral blood of allograft recipients has shown to early identify allograft injury. In this study, we assessed the factors that influence the amount of circulating dd-cfDNA during the first month postkidney transplant as well as its longitudinal trend. A consecutive series of 98 adult kidney transplant recipients at a single center between July 2018 and January 2020 were included in this study.

Alzheimer's disease-associated CD83(+) microglia are linked with increased immunoglobulin G4 and human cytomegalovirus in the gut, vagal nerve, and brain.

Introduction: While there may be microbial contributions to Alzheimer's disease (AD), findings have been inconclusive. We recently reported an AD-associated CD83(+) microglia subtype associated with increased immunoglobulin G4 (IgG4) in the transverse colon (TC).

Methods: We used immunohistochemistry (IHC), IgG4 repertoire profiling, and brain organoid experiments to explore this association.

NEONATAL HYDROMETROCOLPOS: CLINICAL PRESENTATION AND THERAPEUTIC APPROACH.

Hydrometrocolpos (HMC) is a rare pediatric condition characterized by significant enlargement of the uterus and vagina due to the accumulation of fluid, generally caused by a blockage in the lower vagina. This disorder typically presents in newborns with the retention of normal genital tract secretions. The following case report highlights the clinical features, diagnostic process, and treatment of HMC in a newborn.

Efficacy of Bacteriophages in Wound Healing: An Updated Review.

We have attempted to summarize the efficacy of bacteriophage therapy, highlighting the recent advances and phage delivery methods in different clinical trials and animal studies for wound-associated infections. Bacteriophage therapy is the lyse of bacteria by bacteriophages at the site of invasion. As bacteria become more resistant to antibiotics, discovering an alternative is more important than ever, and bacteriophage therapy has yielded promising outcomes.

Design, creation, and use of the Test Us Bank (TUB) COVID-19 sample biorepository.

Shortly after the first case of SARS-CoV-2 was diagnosed a public health emergency (PHE) was declared and a multi-agency response was initiated within the US federal government to create and propagate testing capacity. As part of this response, an unprecedented program designated Rapid Acceleration of Diagnostics (RADx) Tech was established by the National Institutes of Health (NIH) to facilitate the development of point-of-care tests for the COVID-19. The RADx Tech Clinical Studies Core (CSC), located at the University of Massachusetts Chan Medical School (UMass Chan), with partnering academic, private, and non-governmental organizations around the country, was tasked with developing clinical studies to support this work.

Effect of vitamin D supplementation on cardiovascular outcomes: an updated meta-analysis of RCTs.

Objective: To evaluate the effect of vitamin D supplementation on cardiovascular outcomes.

Methods: After searching different databases, we retrieved and included randomized controlled trials on long-term supplementation of vitamin D (≥1-year intervention) and reporting cardiovascular outcomes. We calculated risk ratio (RR) with 95% confidence intervals (CI) for dichotomous outcomes.

Aromatase inhibitors and fracture prevention - do 2017 guidelines work in real world?

Objectives: Aromatase inhibitor induced bone loss (AIBL) is a recognised adverse event with resultant increase in fracture risk. We aimed to determine the real-world impact of the 2017 consensus guidelines on AIBL and see if it is effective in fracture prevention.

Methods: Over a 7-year study period, 1001 women prescribed AI were split in two groups.

Computational Model for Early-Stage Aortic Valve Calcification Shows Hemodynamic Biomarkers.

Heart disease is a leading cause of mortality, with calcific aortic valve disease (CAVD) being the most prevalent subset. Being able to predict this disease in its early stages is important for monitoring patients before they need aortic valve replacement surgery. Thus, this study explored hydrodynamic, mechanical, and hemodynamic differences in healthy and very mildly calcified porcine small intestinal submucosa (PSIS) bioscaffold valves to determine any notable parameters between groups that could, possibly, be used for disease tracking purposes.

Resmetirom: A Systematic Review of the Revolutionizing Approach to Non-alcoholic Steatohepatitis Treatment Focusing on Efficacy, Safety, Cost-Effectiveness, and Impact on Quality of Life.

There has been a rise in the prevalence of non-alcoholic steatohepatitis (NASH), a subset of non-alcoholic fatty liver disease (NAFLD) with an ongoing increase in the prevalence of linked conditions such as obesity, type II diabetes mellitus, and metabolic syndrome. To date, there are no specific drugs that are approved for the treatment of NAFLD/NASH. With the recent discovery of association between subclinical hypothyroidism and NASH, various trials exploring treatment options for NASH using thyroid hormone derivatives led to the discovery of resmetirom (MGL-316) with high affinity to thyroid hormone receptors (THRs) targeting the liver.

Polyarteritis nodosa mimics Kawasaki disease.

Polyarteritis nodosa (PAN) is a rarely seen vasculitis that often affects small-sized and medium-sized arteries. PAN can present with diverse clinical features depending on the organs involved, including potential cardiac involvement. Typical cardiac manifestations of PAN in the paediatric age group include pericarditis, valvular heart disease and coronary artery aneurysms.

Outcomes of Haploidentical Stem Cell Transplant Recipients With HHV-6B Reactivation.

Background: Human herpesvirus 6B (HHV-6B) frequently reactivates following allogeneic stem cell transplant (alloHCT). Consensus guidelines note that haploidentical alloHCT may represent a high-risk population for which there is little evidence; this warrants further investigation.

Methods: In this single-center retrospective study, we evaluated 188 consecutive adult patients receiving haploidentical alloHCT between 11/2014 and 11/2020 and compared outcomes between patients with HHV-6B reactivation receiving targeted antiviral therapy and those who were clinically observed.

A supported primary health pathway for mild traumatic brain injury quality improvement report.

Introduction Best-practice guidelines recommend that patients are followed-up to check if they have recovered following a mild traumatic brain injury (mTBI) and to refer to concussion services, if needed. However, in New Zealand, rates of follow-up are low and access to concussion services can be delayed. Aim We aimed to improve rates of follow-up and access to concussion services for mTBI patients aged ≥8 years by the implementation of a supported health pathway and test its success.

Contribution of the Gut Microbiome to the Perpetuation of Inflammation in Crohn's Disease: A Systematic Review.

Crohn's disease (CD) is a sub-type of inflammatory bowel disease (IBD) with a characteristic relapsing and remitting inflammation involving the gastrointestinal (GI) tract. Although there are several medications to relieve the symptoms, there is no definite cure for the condition. This paper highlights how CD affects our gut flora, which subsequently leads to the perpetuation of inflammation.
