Liver transplantation (LT) is the definitive treatment for end-stage liver disease, acute liver failure, and liver cancer. Although advancements in surgical techniques, postoperative care, and immunosuppressive therapies have significantly improved outcomes, the long-term use of immunosuppression has increased the risk of complications, including infections, cardiovascular disease, and cancer. Among these, malignancies (DNMs) are a major concern, accounting for 20%-25% of deaths in LT recipients surviving beyond the early post-transplant period.

Background: Normothermic machine perfusion (NMP) enables real-time assessment of liver graft viability through various biomarkers. Although lactate clearance during NMP has been associated with graft outcomes, its dynamic patterns and relationship with posttransplant biliary complications (PTBCs) remain poorly understood. We sought to evaluate whether dynamic lactate clearance patterns during NMP could predict PTBCs in both donations after circulatory death (DCD) and brain death (DBD) liver transplantation (LT).

Introduction: Substance P and its neurokinin (NK-1) receptors are upregulated in different pathophysiological conditions. Overexpression of the NK-1 receptor in cancer conditions has provided a promising pathway for cancer treatment. Clinically, Aprepitant (APT) is used as the only NK-1 antagonist in chemotherapy-induced nausea and vomiting (CINV).

Background: Radioligand therapy with [Lu]Lu-PSMA-617 represents an emerging treatment for metastatic castration-resistant prostate cancer (mCRPC). Its clinical positioning relative to standard therapies remains under discussion.

Objective: To compare overall survival (OS), radiographic progression-free survival (rPFS), PSA response, and treatment burden across randomised trials evaluating [Lu]Lu-PSMA-617 versus androgen receptor pathway inhibitors (ARTA), Cabazitaxel, or standard of care (SOC).

Recent events in public health globally have created a need for response by public health researchers in all disciplines to evaluate impact on health, morbidity and mortality of the COVID-19 pandemic that has engulfed the world after 100 years of previous influenza pandemic. Most of the immediate responses, globally; have focused on diagnosis and management of severe cases. However, for evolution of policies dealing with population health in the post COVID-19 era, community-based data for rates of morbidity, risk factors of illness and severity and outcomes of influenza like illness in Maternal, Neonatal and Child Health (MNCH) is needed to inform evidence-based policy.

Tracheal atresia (TA) is a rare condition and is accompanied by various congenital abnormalities. In our study of two cases, the patient's condition led to challenging resuscitation efforts after birth, ultimately resulting in an unfortunate outcome. Despite collaborative interventions by multiple medical teams, neither of the baby in both cases could be saved.

Background: Portal vein thrombosis in liver transplant recipients presents a significant challenge, with potential implications for posttransplant biliary complications. This study investigated the relationship between portal vein thrombosis and posttransplant biliary complications, aiming to identify risk factors and establish a stratification framework.

Methods: We conducted a single-center retrospective study of 914 adult liver transplant recipients from 2016 to 2023.

Human immunodeficiency virus (HIV) modifies CD4-positive cells, resulting in immunodeficiency and a wide range of gastrointestinal (GI) manifestations. The burden of HIV-related GI illnesses has significantly evolved with the widespread use of antiretroviral therapy (ART). While ART has effectively reduced the occurrence of opportunistic infections, it has led to an increase in therapy-related GI illnesses.

Introduction: Hypotension is a frequent complication of patients who are on chronic maintenance hemodialysis. Midodrine is an alpha-1 adrenergic agonist used to treat patients on hemodialysis who have chronic hypotensiom. The aim of our study was to evaluate if patients who required midodrine for hypotension had inferior outcomes compared to those who did not require midodrine.

Kidney allograft torsion (KAT) is a rare but critical complication of kidney transplantation that can lead to graft loss due to acute ischemia. This report presents a case of KAT resulting in graft loss 9 months following intraperitoneal simultaneous pancreas and kidney (SPK) transplant and reviews previous reports to identify potential high-risk features. A 38-year-old female with end-stage renal disease secondary to Type 1 diabetes mellitus underwent an intraperitoneal enteric drained SPK transplant.

Background: Weekend hospital discharges are often associated with reduced staffing, potentially impacting the quality of patient care. We studied the effects of weekend discharge after liver transplantation (LT) on early readmission rates, overall survival (OS), and graft survival (GS).

Method: We analyzed data from the Ohio State University Wexner Medical Center database (January 2016 to December 2023).

The American Society for Pain Management Nursing (ASPMN) upholds the principle that all persons with pain have equal rights to evidence-based, high quality pain assessment, management, and treatment. This practice recommendation's goals are to 1) summarize known pain-related disparities, inequities, and injustices among commonly marginalized and at risk groups, 2) offer recommendations to ascertain that just and equitable pain care is provided to all people, and 3) outline a call to action for all nurses to embrace diversity, equity, inclusion, and a sense of belonging in order to mitigate pain-related disparities, inequities, and injustices within clinical environments and the nursing profession. This paper provides background and rationale for the 2024 ASPMN position statement on disparities, inequities and injustices in people with pain.

Magnetic resonance imaging (MRI) provides detailed structural information of the internal body organs and soft tissue regions of a patient in clinical diagnosis for disease detection, localization, and progress monitoring. MRI scanner hardware manufacturers incorporate various post-acquisition image-processing techniques into the scanner's computer software tools for different post-processing tasks. These tools provide a final image of adequate quality and essential features for accurate clinical reporting and predictive interpretation for better treatment planning.

Objectives: Liquid biopsy, with its noninvasive nature and ability to detect tumor-specific genetic alterations, emerges as an ideal biomarker for monitoring recurrences for locally advanced rectal cancer (LARC). Completed studies have small sample sizes and different experimental methods. To consolidate and assess the collective evidence regarding the prognostic role of circulating DNA (ctDNA) detection in LARC patients undergoing neoadjuvant chemoradiotherapy (nCRT).

Article Synopsis
  • - Hydrophobic pollutants like long-chain hydrocarbons and heavy metals are harmful to the environment and human health, and traditional chemical surfactants used for decontamination can be toxic.
  • - Biosurfactants, produced by various microbes, are a safer and more cost-effective alternative to chemical surfactants, capable of breaking down pollutants and enhancing their solubility by reducing surface tension.
  • - The effectiveness of biosurfactants in remediation depends on several factors such as temperature, pH, and media composition, and recent discussions include their potential in a circular bioeconomy by utilizing waste for biosurfactant production.

Background: There is limited literature describing the real-world practice of delayed initiation and shortened duration direct-acting antiviral (DAA) in kidney transplant recipients. We compared Hepatitis C virus (HCV) cure rates among kidney transplant recipients who received an HCV nucleic acid test positive (NAT +) kidney and were treated with sofosbuvir/velpatasvir (SOF/VEL) for 12 weeks or glecaprevir/pibrentasvir (G/P) for 8 weeks, a duration that is 4 weeks shorter than the guideline recommendation for treatment delay beyond 1-week post-transplant.

Methods: Retrospective study of HCV-negative adult patients who received a kidney transplant from an HCV NAT+ donor between April 2019 and April 2022 treated with either SOF/VEL for 12 weeks or G/P for 8 weeks.
