Article Abstract
What Is Known And Objective: Nafamostat mesylate (NM) is used clinically in combination with antiviral drugs to treat coronavirus disease (COVID-19). One of the adverse events of NM is hyperkalaemia due to inhibition of the amiloride-sensitive sodium channels (ENaC). The incidence and risk factors for hyperkalaemia due to NM have been studied in patients with pancreatitis but not in COVID-19. COVID-19 can be associated with hypokalaemia or hyperkalaemia, and SARS-CoV-2 is thought to inhibit ENaC. Therefore, frequency and risk factors for hyperkalaemia due to NM may differ between COVID-19 and pancreatitis. Hyperkalaemia may worsen the respiratory condition of patients. The objective of this study was to determine the incidence and risk factors for hyperkalaemia in COVID-19 patients treated with favipiravir, dexamethasone and NM.
Methods: This retrospective study reviewed the records of hospitalized COVID-19 patients treated with favipiravir and dexamethasone, with or without NM, between March 2020 and January 2021. Multivariable logistic regression analysis was performed to identify the risk factors for hyperkalaemia.
Results And Discussion: Of 45 patients who received favipiravir and dexamethasone with NM for the treatment of COVID-19, 21 (47%) experienced hyperkalaemia. The duration of NM administration was a significant predictor of hyperkalaemia (odds ratio: 1.55, 95% confidence interval: 1.04-2.31, p = 0.031). The receiver-operating characteristic curve analysis determined that the cut-off value for predicting the number of days until the onset of hyperkalaemia was 6 days and the area under the curve was 0.707.
What Is New And Conclusion: This study revealed that the incidence of hyperkalaemia is high in patients treated for COVID-19 with NM, and that the duration of NM administration is a key risk factor. When NM is administered for the treatment of COVID-19, it should be discontinued within 6 days to minimize the risk of hyperkalaemia.

Risk of colorectal cancer and participation in fecal immunochemical test-based screening.

Objectives: Participation rates in fecal immunochemical test (FIT)-based colorectal cancer (CRC) screening differ across socio-demographic subgroups. The largest health gains could be achieved in subgroups with low participation rates and high risk of CRC. We investigated the CRC risk within different socio-demographic subgroups with low participation in the Dutch CRC screening program.

Animal allergens, particularly those from cats, dogs, and horses, are significant risk factors for the development of allergic diseases in childhood. Managing animal allergies requires allergen avoidance and, when this is not feasible, specific immunotherapy. Patient history remains the cornerstone of diagnosis, providing the foundation for diagnostic algorithms.

Background: Vascular changes are observed in children with cystic fibrosis (cwCF), and gender-specific differences may impact arterial stiffness. We aimed to compare arterial stiffness and clinical parameters based on gender in cwCF and to determine the factors affecting arterial stiffness in cwCF.
Methods: Fifty-eight cwCF were included.

Background: In-hospital cardiac arrest (IHCA) remains a public health conundrum with high morbidity and mortality rates. While early identification of high-risk patients could enable preventive interventions and improve survival, evidence on the effectiveness of current prediction methods remains inconclusive. Limited research exists on patients' prearrest pathophysiological status and predictive and prognostic factors of IHCA, highlighting the need for a comprehensive synthesis of predictive methodologies.

Post-transplant lymphoproliferative disorder is a rare and serious complication of organ and stem cell transplant secondary to immunosuppressive therapies, most commonly of monomorphic B-cell subtype. Here we describe the first reported case of a pediatric heart transplant patient who developed both monomorphic B-cell and nondestructive PTLD with plasmacytic hyperplasia followed by an unrelated case of monomorphic T-cell and nondestructive PTLD with plasmacytic hyperplasia, which later relapsed. We detail the patient's risk factors for development of PTLD and her successful treatment regimens.
