Background Seropositivity to Jamestown Canyon Virus Can Lead to Diagnostic Confusion
No full textBackground seropositivity rates for specific antibodies to Jamestown Canyon Virus (JCV) can exceed 25 % in certain geographic areas in the United States. This can potentially lead to diagnostic confusion, as apparently illustrated by a patient from New Jersey with Powassan virus encephalitis, who also tested positive for antibodies to JCV
Single-Cell Multi-Ome and Immune Profiles of the Inspiration4 Crew Reveal Conserved, Cell-Type, and Sex-Specific Responses to Spaceflight
No full textSpaceflight induces an immune response in astronauts. To better characterize this effect, we generated single-cell, multi-ome, cell-free RNA (cfRNA), biochemical, and hematology data for the SpaceX Inspiration4 (I4) mission crew. We found that 18 cytokines/chemokines related to inflammation, aging, and muscle homeostasis changed after spaceflight. In I4 single-cell multi-omics data, we identified a spaceflight signature of gene expression characterized by enrichment in oxidative phosphorylation, UV response, immune function, and TCF21 pathways. We confirmed the presence of this signature in independent datasets, including the NASA Twins Study, the I4 skin spatial transcriptomics, and 817 NASA GeneLab mouse transcriptomes. Finally, we observed that (1) T cells showed an up-regulation of FOXP3, (2) MHC class I genes exhibited long-term suppression, and (3) infection-related immune pathways were associated with microbiome shifts. In summary, this study reveals conserved and distinct immune disruptions occurring and details a roadmap for potential countermeasures to preserve astronaut health
Synergizing Safety: A Customized Approach to Curtailing Unplanned Extubations Through Shared Decision-Making in the NICU
No full textBACKGROUND: Unplanned Extubation (UE) remains an important patient safety issue in the Neonatal Intensive Care Unit. Our SMART AIM was to decrease the rate of UE by 10% from the baseline from January to December 2022 by emphasizing collaboration among healthcare professionals and through the use of shared decision-making. METHODS: We established an interdisciplinary Quality Improvement team composed of nurses, respiratory therapists, and physicians (MDs). The definition of UE was standardized. UE was audited using an apparent cause analysis form to discern associated causes and pinpoint areas for improvement. Interventions were implemented in a step-by-step fashion and reviewed monthly using the model for improvement. A shared decision-making approach fostered collaborative problem-solving. RESULTS: Our baseline UE rate was 2.3 per 100 ventilator days. Retaping, general bedside care, and position change accounted for over 50% of the UE events in 2022. The rate of UE was reduced by 48% by the end of December 2022. We achieved special-cause variation by the end of March 2023. CONCLUSIONS: The sole education of medical and nursing providers about various approaches to decreasing unnecessary retaping was ineffective in reducing UE rates. Shared decision-making incorporating inputs from nurses, respiratory therapists, and MDs led to a substantial reduction in the UE rate and underscores the potential of systematic evaluation of risk factors combined with collaborative best practices
Public Health Response to Sars-Cov-2 in Assisted Living Facilities in New York State: March 2020-December 2022
No full textCONTEXT: Assisted living facility (ALF) residents are especially vulnerable to SARS-CoV-2 infection due to the age and comorbidities of the resident population and the social nature of these facilities. OBJECTIVE: To collate all New York State Department of Health guidance and regulations to control transmission of SARS-CoV-2 infection within ALFs from March 2020 through December 2022 and to include US Food and Drug Administration COVID-19 testing and vaccine authorizations. DESIGN: A narrative chronological review of all New York State Department of Health guidance. RESULTS: Documents and associated guidance and regulations are divided into 4 sections: (1) lockdown until COVID-19 vaccine emergency use authorization; (2) COVID-19 vaccine authorization until phased reopening; (3) phased reopening, vaccination requirements, and booster vaccination; (4) the period of the bivalent booster. CONCLUSION: Controlling the spread of SARS-CoV-2 within ALFs required a multifactorial approach that included stringent infection control measures, testing, and vaccination and careful attention to the social structure and support systems within ALFs. The SARS-CoV-2 pandemic highlighted the complexity of controlling spread of an easily transmissible respiratory pathogen in assisted living communities and the need to structure infection control programs within the diverse ALFs that provide care for our aging population
Repair of Radiation-Induced Rectovaginal Fistula With Rectal Stricture by a Combined Tuttle, Turnbull-Cutait and Singapore Flap Approach
No full textRadiation-induced rectovaginal fistula (RI-RVF) with associated rectal stricture represents a challenging problem in management. The aim of the present technical note is to describe a surgical technique aimed at minimizing disease recurrence by avoiding radiated tissue in the reconstruction: 1. Tuttle longitudinal incision of posterior vaginal wall with sharp excision of proximally located fistula; 2. Resection of strictured rectum via a combined transvaginal/laparotomy access, reconstruction with Turnbull-Cutait colon pull-through, and delayed handsewn coloanal anastomosis with loop ileostomy; 3. Bridge closure of the posterior vaginal wall by the interposition of a Singapore flap. This approach resulted in a favorable outcome at the 1-year follow-up in one patient with a medical history of gynecological carcinoma status after hystero-salpingo-oophorectomy followed by adjuvant radiation
Management of Isocitrate Dehydrogenase 1/2 Mutated Acute Myeloid Leukemia
No full textThe emergence of next generation sequencing and widespread use of mutational profiling in acute myeloid leukemia (AML) has broadened our understanding of the heterogeneous molecular basis of the disease. Since genetic sequencing has become a standard practice, several driver mutations have been identified. Accordingly, novel targeted therapeutic agents have been developed and are now approved for the treatment of subsets of patients that carry mutations in FLT3, IDH1, and IDH2 [1, 2]. The emergence of these novel agents in AML offers patients a new modality of therapy, and shifts treatment paradigms toward individualized medicine. In this review, we outline the role of IDH mutations in malignant transformation, focus in on a novel group of targeted therapeutic agents directed toward IDH1- and IDH2-mutant AML, and explore their impact on prognosis in patients with AML
