Clostridium difficile infection (CDI) is the most common nosocomial infection in hospitals. Despite the fact that CDI has treatment options, recurrence is common after the treatment, recurrence will occur in approximately 20%-35% of people initially affected, with 40%-60% of these having a second recurrence. Patients are more likely to have several recurrences after the second, which can lead to antibiotic overuse, and as a result, CDI-related health care expenses, hospitalizations, and mortality are on the rise. The first treatment to receive Food and Drug Administration (FDA) approval for the prevention of C. difficile recurrence is bezlotoxumab, a novel human monoclonal antibody against C. difficile toxin B. In the present systematic review, we assessed various studies from PubMed, PubMed Central (PMC), Google Scholar, and Science direct that evaluated the efficacy of bezlotoxumab in the prevention of recurrent C. difficile (rCDI), and we also briefly discussed the pathophysiology of C. difficile and the risk factors for recurrence of C. difficile. The major MODIFY trial has proven the efficacy, pooled analysis of MODIFY 1 AND 2 trials demonstrated the following results as compared to placebo (bezlotoxumab
Chimeric Antigen Receptor (CAR)-T cell therapy has been one of the most important breakthroughs for treating hematologic malignancies. On the other hand, the therapy had many toxicities. One of the toxicities of the CAR-T therapy is cardiotoxicity. The goal of the systematic review is to elaborate on the cardiotoxicities related to CAR-T therapy for hematologic malignancies. The systematic review is following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020 guidelines. The systematic search was done using PubMed, PubMed Central (PMC), Google Scholar, Cochrane Library, ScienceDirect, and clinicaltrial.gov. The search and selection of studies were done on April 28, 2022, and May 6, 2022, respectively. The studies were selected based upon participants, intervention, and outcomes (PIO) elements and the articles that were included were, full-text articles published within the last ten years, clinical trials, meta-analyses, randomized controlled trial, review, and systematic review. The exclusion criteria were non-hematologic malignancy, non-English-language articles. The initial search had 2,159 publications. The publications were assessed with assessment tools of Scale of the Assessment of Narrative Review Articles (SANRA), Newcastle-Ottawa Scale (NCOS), and Cochrane Collaboration Risk of Bias Tool (CCRBT), which led to selection of eight publications. The systematic review concludes that cardiotoxicity happened in adults and pediatric patients receiving the CAR-T cell therapy and that those cardiac adverse events had many risk factors. Therefore, monitoring these cardiotoxicities is highly essential.
Sjogren's syndrome is an autoimmune disorder of the body's exocrine glands; however, it is known to have numerous extra-glandular and endocrine manifestations in the body. Moreover, other autoimmune have also been reported with high prevalence in patients with Sjogren's syndrome, including thyroid diseases. Therefore in this study, we aimed to ascertain the increased risk of developing thyroid disorders in patients with pre-existing Sjogren's syndrome. The systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Online searches on PubMed, PubMed Central (PMC), Google Scholar, and Cochrane were done till 5th June 2022 to filter out studies published in the last twenty years. Based on the inclusion-exclusion criteria, 167 studies were initially selected. They were screened and assessed by quality assessment tools that yielded seven studies, including one meta-analysis, three non-randomized control trials, and three systematic reviews. The study proved that patients with Sjogren's syndrome are at significant risk of developing thyroid disorders, especially autoimmune thyroiditis. This also highlights the need for advanced research and better diagnostic and screening protocols for these patients to reduce the seriousness of the disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
