Clinical outcomes and care for spontaneous bacterial peritonitis: A national cohort study.

Background And Aims: Spontaneous bacterial peritonitis (SBP) leads to high rates of acute kidney injury (AKI), hepatorenal syndrome, and mortality. Population-based studies on contemporary SBP epidemiology are needed to inform care. In a large, national cohort of patients diagnosed with SBP and confirmed by ascitic fluid criteria, we characterized ascitic fluid characteristics, in-hospital and 12-month mortality, AKI, and recurrent SBP.

Ibrutinib for therapy of steroid-refractory chronic graft-versus-host disease: a multicenter real-world analysis.

To examine the activity of ibrutinib in steroid-refractory chronic graft-versus-host disease (SR-cGVHD) after the US Food and Drug Administration approval, we conducted a multicenter retrospective study. Data were standardly collected (N = 270 from 19 centers). Involved organs included skin (75%), eye (61%), mouth (54%), joint/fascia (47%), gastrointestinal (GI) (26%), lung (27%), liver (19%), genital (7%), and others (4.

Molecular Diagnostics for Invasive Fungal Diseases: Current and Future Approaches.

Invasive fungal diseases (IFDs) comprise a growing healthcare burden, especially given the expanding population of immunocompromised hosts. Early diagnosis of IFDs is required to optimise therapy with antifungals, especially in the setting of rising rates of antifungal resistance. Molecular techniques including nucleic acid amplification tests and whole genome sequencing have potential to offer utility in overcoming limitations with traditional phenotypic testing.

Waitlisting and liver transplantation for MetALD in the United States: An analysis of the UNOS national registry.

Background And Aims: The new steatotic liver disease (SLD) nomenclature introduced metabolic and alcohol-associated liver disease (MetALD), describing the intersection of metabolic dysfunction-associated steatotic liver disease and alcohol-associated liver disease. Waitlisting and liver transplantation for MetALD are not well defined. We aimed to develop and validate an algorithm for identifying SLD phenotypes and assessing trends in waitlisting and transplant outcomes.

Performance of Urinalysis Parameters in Predicting Urinary Tract Infection: Does One Size Fit All?

In a multihospital cohort study of 3392 patients, positive urinalysis parameters had poor positive predictive value for diagnosing urinary tract infection (UTI). Combined urinalysis parameters (pyuria or nitrite) performed better than pyuria alone for ruling out UTI. However, performance of all urinalysis parameters was poor in older women.

National Trends in Utilization of Normothermic Machine Perfusion in DCD Liver Transplantation.

Background: In liver transplantation, advances in ex situ normothermic machine perfusion (NMP) have improved outcomes compared with traditional static cold storage (SCS) in donation after circulatory death (DCD) organs. We aimed to characterize trends in the utilization of NMP versus SCS in DCD liver transplantation in the United States.

Methods: This retrospective cohort study used data from the United Network for Organ Sharing database to identify recipient-donor adult liver transplant pairs from DCD donors from January 2016 to June 2022.

The Impact of Weight Loss Programs on BMI Trajectory in Patients with Metabolic Dysfunction-Associated Steatotic Liver Disease: A Veterans Health Administration Study.

Background: Weight loss is the mainstay of management for patients with metabolic dysfunction-associated steatotic liver disease. We studied the impact of referral to MOVE!, a nationally-implemented behavioral weight loss program, on weight in MASLD patients.

Methods: This retrospective cohort study included 102,294 MASLD patients from 125 Veterans Health Administration centers from 2008-2022.

Efficacy of probiotic treatment as post-exposure prophylaxis for COVID-19: A double-blind, Placebo-Controlled Randomized trial.

Background & Aims: The COVID-19 pandemic continues to pose unprecedented challenges to worldwide health. While vaccines are effective, additional strategies to mitigate the spread/severity of COVID-19 continue to be needed. Emerging evidence suggests susceptibility to respiratory tract infections in healthy subjects can be reduced by probiotic interventions; thus, probiotics may be a low-risk, low-cost, and easily implementable modality to reduce risk of COVID-19.

Ischemic Colitis Due to Idiopathic Myointimal Hyperplasia of the Mesenteric Veins.

Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare and poorly understood noninflammatory ischemic colitis. First reported by Genta and Haggitt in 1991, the disease typically presents with chronic abdominal pain, weight loss, and diarrhea with or without hematochezia in middle-aged men. IMHMV is frequently misdiagnosed as an inflammatory bowel disease.

Incidence, characteristics, risk factors and outcomes of diabetic ketoacidosis in COVID-19 patients: Comparison with influenza and pre-pandemic data.

Aims: This study characterized incidence, patient profiles, risk factors and outcomes of in-hospital diabetic ketoacidosis (DKA) in patients with COVID-19 compared with influenza and pre-pandemic data.

Methods: This study consisted of 13 383 hospitalized patients with COVID-19 (March 2020-July 2022), 19 165 hospitalized patients with influenza (January 2018-July 2022) and 35 000 randomly sampled hospitalized pre-pandemic patients (January 2017-December 2019) in Montefiore Health System, Bronx, NY, USA. Primary outcomes were incidence of in-hospital DKA, in-hospital mortality, and insulin use at 3 and 6 months post-infection.

Geriatric Assessment Reveals Actionable Impairments in Hematopoietic Stem Cell Transplantation Candidates Age 18 to 80 Years.

Allogeneic hematopoietic stem cell transplantation (HCT) is a potentially curative treatment for both malignant and nonmalignant hematologic diseases; however, reported rates of treatment-related mortality approach 30%. Outcomes are worse in patients who begin HCT with functional impairments. To detect such impairments, a geriatric assessment (GA) is recommended in adults age ≥65 years.

Home-Based Hematopoietic Cell Transplantation in the United States.

Patients undergoing allogeneic (allo) and autologous (auto) hematopoietic cell transplantation (HCT) require extensive hospitalizations or daily clinic visits for the duration of their transplantation. Home HCT, wherein patients live at home and providers make daily trips to the patient's residence to perform assessments and deliver any necessary interventions, may enhance patient quality of life and improve outcomes. We conducted the first study of home HCT in the United States to evaluate this model in the US healthcare setting and to determine the effect on clinical outcomes and quality of life.

Biosimilar Pegfilgrastim-cbqv Demonstrated Similar Immunogenicity to Pegfilgrastim in Healthy Subjects Across Three Randomized Clinical Studies.

Introduction: Biologic therapeutics can trigger immune responses in patients. As part of the totality of evidence that is required for regulatory approval of biosimilars, immunogenicity similarity must be assessed in the clinical programs. Pegfilgrastim-cbqv (UDENYCA) is a pegfilgrastim biosimilar approved in the USA and European Union.

Female Sex Is Associated with Improved Long-Term Survival Following Allogeneic Hematopoietic Stem Cell Transplantation.

Life expectancy for long-term survivors of allogeneic hematopoietic stem cell transplantation (alloHSCT), defined as those living ≥5 years post-transplantation, is significantly lower compared with that of the age-matched general population despite a relatively low primary disease relapse rate at >2 years post-transplantation. Among several factors, patient sex is increasingly recognized as a prognostic indicator of long-term survival. We examined the influence of patient sex and donor-recipient sex matching on overall survival (OS) in a landmark analysis of long-term survivors.

Decreased Mortality in 1-Year Survivors of Umbilical Cord Blood Transplant vs. Matched Related or Matched Unrelated Donor Transplant in Patients with Hematologic Malignancies.

Allogeneic hematopoietic stem cell transplantation (HCT) has the potential to cure hematologic malignancies but is associated with significant morbidity and mortality. Although deaths during the first year after transplantation are often attributable to treatment toxicities and complications, death after the first year may be due to sequelae of accelerated aging caused by cellular senescence. Cytotoxic therapies and radiation used in cancer treatments and conditioning regimens for HCT can induce aging at the molecular level; HCT patients experience time-dependent effects, such as frailty and aging-associated diseases, more rapidly than people who have not been exposed to these treatments.

Randomised, double-blind, placebo-controlled trial of Probiotics To Eliminate COVID-19 Transmission in Exposed Household Contacts (PROTECT-EHC): a clinical trial protocol.

Introduction: The COVID-19 pandemic has proven to be an unprecedented challenge to worldwide health, and strategies to mitigate the spread and severity of COVID-19 infection are urgently needed. Emerging evidence suggests that the composition of the gut microbiome and modification of microbial ecology via probiotics can affect susceptibility to a wide range of infections, including respiratory tract infections. In this study, we aim to evaluate the effects of the probiotic (LGG) versus placebo on COVID-19 infection status and the gut microbiome in subjects with a household contact who has tested positive for COVID-19.

Aneuploidy renders cancer cells vulnerable to mitotic checkpoint inhibition.

Selective targeting of aneuploid cells is an attractive strategy for cancer treatment. However, it is unclear whether aneuploidy generates any clinically relevant vulnerabilities in cancer cells. Here we mapped the aneuploidy landscapes of about 1,000 human cancer cell lines, and analysed genetic and chemical perturbation screens to identify cellular vulnerabilities associated with aneuploidy.
