Abstract In recent years, there has been increasing interest in the possible prognostic impact of concomitant medications in patients with cancer treated with immunotherapy combinations. This real‐world analysis aims to evaluate the impact of concomitant medications on survival outcomes in patients with advanced biliary tract cancer (BTCs) treated with cisplatin, gemcitabine and durvalumab (CGD) therapy. The study cohort included patients with a diagnosis of advanced BTCs who were taking concomitant medications for their comorbidities before the start of CGD. The primary objectives were overall survival (OS) and progression‐free survival (PFS). The initial population consisted of 666 patients, who were retrospectively collected from 41 sites in 12 countries. Data on concomitant medications were available for 493 patients. After a median follow‐up of 8.8 months (95% CI: 7.8–9.8), patients who did not take steroids (prednisone >10 mg/day or equivalent) or nonsteroidal anti‐inflammatory drugs (NSAIDs) and opioids, before the start of CGD, had longer OS and PFS in univariate analysis. The multivariate analysis confirmed longer OS for patients who did not take steroids. Patients who did not take steroids had an OS of 14.8 months (95% CI: 13.1–29.1) versus 5.0 months (95% CI: 2.14–11.32) of patients who took prednisone >10 mg/day or equivalent. No differences were reported in terms of overall response rate (ORR), disease control rate (DCR) ( p = 1.0 and p = .16, respectively), and safety profile between the two groups. Our analysis suggests that patients who did not receive steroids before the start of GCD had longer survival and highlighted the relevance of balancing concomitant medications and chemoimmunotherapy.

Background/Objectives: Transcatheter aortic valve replacement (TAVR) has been introduced as an optimal treatment for patients with severe aortic stenosis, offering a minimally invasive alternative to surgical aortic valve replacement. Predicting these outcomes following TAVR is crucial. Artificial intelligence (AI) has emerged as a promising tool for improving post-TAVR outcome prediction. In this systematic review and meta-analysis, we aim to summarize the current evidence on utilizing AI in predicting post-TAVR outcomes. Methods: A comprehensive search was conducted to evaluate the studies focused on TAVR that applied AI methods for risk stratification. We assessed various ML algorithms, including random forests, neural networks, extreme gradient boosting, and support vector machines. Model performance metrics—recall, area under the curve (AUC), and accuracy—were collected with 95% confidence intervals (CIs). A random-effects meta-analysis was conducted to pool effect estimates. Results: We included 43 studies evaluating 366,269 patients (mean age 80 ± 8.25; 52.9% men) following TAVR. Meta-analyses for AI model performances demonstrated the following results: all-cause mortality (AUC = 0.78 (0.74–0.82), accuracy = 0.81 (0.69–0.89), and recall = 0.90 (0.70–0.97); permanent pacemaker implantation or new left bundle branch block (AUC = 0.75 (0.68–0.82), accuracy = 0.73 (0.59–0.84), and recall = 0.87 (0.50–0.98)); valve-related dysfunction (AUC = 0.73 (0.62–0.84), accuracy = 0.79 (0.57–0.91), and recall = 0.54 (0.26–0.80)); and major adverse cardiovascular events (AUC = 0.79 (0.67–0.92)). Subgroup analyses based on the model development approaches indicated that models incorporating baseline clinical data, imaging, and biomarker information enhanced predictive performance. Conclusions: AI-based risk prediction for TAVR complications has demonstrated promising performance. However, it is necessary to evaluate the efficiency of the aforementioned models in external validation datasets.

Introduction Alzheimer’s disease and related dementias (ADRD) are conditions with progressive cognitive decline. Still, people living with late-stage ADRD (PLWD) have been reported to exhibit transient recovery of communication or behavioural abilities that had seemingly been lost. These lucid episodes (LEs) are underinvestigated and poorly understood. This study aims to advance scientific understanding of the incidence, prevalence and predictors of LEs and assess from family caregivers if LEs are associated with changes they make in care planning or experiences with burden, distress or grief. Methods This study recruited 545 caregivers from five ADRD-related registries in the USA. Eligibility included caregivers over 18 years who currently provide care to someone with moderate to very severe ADRD and can complete online questionnaires. Using a longitudinal observational study design, consented caregivers will be assessed monthly for 1 year using online questionnaires that inquire about witnessing LEs. If witnessed, the context and content of the LE is reported. Changes in caregiver decision-making about care for the PLWD, and caregiver burden, distress and grief are assessed at baseline, 6 and 12 months. Analysis Analysis of baseline data will assess descriptive aspects of LEs that are currently unknown (eg, prevalence, content, antecedents, duration). Longitudinal analysis will examine the incidence of LEs, characteristics of PLWD and caregivers that are predictors of episodes, and the associations between LEs and caregiver outcomes (eg, burden, distress, grief). Ethics and dissemination This study is being conducted in accordance with all Federal Policies for the Protection of Human Subjects. The protocol has been approved by the Mayo Clinic Institutional Review Board (ID 22-006861). Findings will be presented at scientific conferences and disseminated through journal publications and outreach efforts with collaborating partners invested in brain health and caregiver support.

AimsMucinous cystic neoplasms (MCN) are defined by the presence of an ovarian‐type stroma (OTS). Once ovarian stroma has become a requirement for the diagnosis of MCNs, studies using this criterion have disclosed that MCNs are seen almost exclusively (97%) in women. The occurrence of MCNs (with ovarian stroma) in men is exceedingly rare and raises questions about the origin of OTS and the role of hormones in tumourigenesis. This study aims to investigate the clinical and histopathological features of pancreatic or hepatic MCNs in men.Methods and resultsWe examined the MCN cases in men and compared them with age‐matched women. We further investigated MCN in premenopausal and postmenopausal women to explore the impact of hormonal status.The stromal cellularity tended to be lower in men as compared to women; however, limited numbers prevented statistical significance. Clinical presentation, tumour location, body mass index and cyst complexity were similar between men and age‐matched women, similarly in pre‐ and postmenopausal woman groups. All MCN cases, regardless of gender or hormonal status, showed OTS with positivity for oestrogen receptor (ER), androgen receptor (AR) and SF‐1 immunostains. Additionally, the presence of AR and ER‐beta in lining epithelial cells, in addition to the stromal cells, raised the probability for a potential role for local hormonal signalling in the pathogenesis of these tumours.ConclusionsMCNs in men had overlapping histopathologic and immunohistochemical profiles with those in women, regardless of menopausal status.

In this brief review we discuss the potential reasons underlying and follow up of patients who have a positive non-endoscopic swallowable cell collection device+biomarker (such as TFF3) test but no evidence of Barrett’s esophagus on endoscopy. We discuss the potential role of careful examination of the gastroesophageal junction and targeted biopsies of any visible lesions, as well endoscopic follow up in 3-5 years in the absence of any alarm symptoms. Considerations of the use of new technologies such as wide area transepithelial sampling in this situation are also discussed.

Abstract Nephrocalcinosis provides a nidus for stone formation and is strongly linked to renal injury and chronic kidney disease. Although the crucial role of macrophages in the formation and progression of calcium oxalate (CaOx) crystals has long been widely recognized, finding effective immunotherapies for nephrocalcinosis remains a challenge. In this study, we described an innovative macrophage‐based method that delivers interleukin‐10 (IL‐10) into the kidney, reduces the deposition of CaOx crystals, and alleviates renal injury in a mouse model of glyoxylate‐induced CaOx. Compared with recombinant IL‐10 direct injection, the macrophage‐based method has the advantages of biocompatibility and sustaining action. We found that the transplantation of engineered macrophages via the tail vein significantly reduced the volume of crystals in the kidney, thereby alleviating the kidney injury caused by crystal. In mechanistic studies, IL‐10‐secreting macrophages inhibited crystal formation and promoted crystal clearance by promoting macrophage M2 polarization, exerting a protective effect on renal tissue. Our data suggest that macrophage‐based delivery of IL‐10 to the kidney can be a potential treatment method for nephrocalcinosis.

Background Excellence in healthcare delivery is dependent on individuals working together on a team. Objective We sought to enhance team performance by partnering with human resources (HR) to identify opportunities unrecognised by unit leadership. Methods 100 individuals representing a cross-section of the multidisciplinary team participated in an interview focused on teamwork conducted by an HR representative. Action plans were then developed and implemented. Press Ganey Survey results for the question, “Staff worked together to care for you/your baby?” were tracked to assess patient perception of teamwork. Results Between 2022 and 2024, we observed improvement in the per cent of patients who assigned the highest rating of teamwork, culminating in 100% of patients reporting the highest score in the final quarter. Conclusion The model of HR facilitated discussions with work unit team members identified barriers to optimal teamwork, led to the implementation of action plans and resulted in an improvement in our teamwork rating by patients.

ABSTRACT. This cross-sectional descriptive study was conducted at the University of Health Sciences, Lahore, over 5 years (2016–2020) to explore the association of Panton–Valentine leucocidin (pvl) genes and staphylococcal cassette chromosome mec (SCCmec) types with hospital-acquired (HA) and community-acquired methicillin-resistant Staphylococcus aureus (MRSA). Panton–Valentine leucocidin genes in MRSA have been found in HA-MRSA strains, thereby raising the prevalence of highly virulent and resistant strains. Furthermore, the usage of staphylococcal cassette chromosome mec (SCCmec) typing is crucial for understanding the epidemiology and evolution of MRSA. The isolates of Staphylococcus aureus were acquired from clinical samples of the patients. Gram staining, catalase, coagulase, and DNAse tests were used for S. aureus confirmation. The methicillin resistance genes A and C (mecA and mecC) genes were detected to confirm MRSA by using a 30 µg cefoxitin disk. Panton–Valentine leucocidin gene identification and SCCmec typing (types I–V and XI) were conducted through polymerase chain reaction testing. Only 440 strains of MRSA were isolated, and 31.6% were positive for the pvl gene. The most prevalent SCCmec type among the MRSA isolates was type III, which was found in 42.7% of isolates. The pvl gene was detected in 74% of SCCmec types IV and V and in only 14% of SCCmec types I, II, III, and IIIA. This study revealed the dynamic adaptability of MRSA strains within healthcare settings, with the cooccurrence of the pvl gene and various SCCmec types highlighting the complexity of MRSA epidemiology. The urgent implementation of comprehensive strategies that integrate molecular surveillance and infection control measures is crucial for mitigating MRSA.
