Real-world evidence of tumor and patient characteristics and survival with avelumab maintenance after chemotherapy for advanced and metastatic urothelial carcinoma.

PURPOSE: Despite the prospective randomized controlled JAVELIN Bladder 100 trial, no real-world evidence exists regarding tumor characteristics, adverse events (AE) and survival of avelumab maintenance (AVM) treated patients with partial/complete response or stable disease after previous platinum-based chemotherapy for advanced/metastatic urothelial carcinoma (mUC). METHODS: We relied on our institutional database to identify mUC patients who received AVM between 01/2021-12/2023. The main outcomes consisted of overall (OS) and progression-free survival (PFS) and were computed by Kaplan-Meier estimates. Stratification was performed according to PD-L1 status. RESULTS: Overall, 24 AVM patients were identified at a median age of 71 (interquartile range [IQR]: 67-76) years of which 67% were males. Of these, 63%, 21% and 17% received AVM therapy for bladder cancer and upper tract urothelial carcinoma or both, respectively. PD-L1 status was positive in 45% of patients. During AVM treatment, AEs were observed in 33% of patients, however, were limited to ≤2 grade AEs. At a median follow-up of eight (IQR 4-20) months, 71% of patients had progressed under AVM with median PFS of 6.2 months (CI: 3.2-18.2). Median OS was 13.4 (CI: 6.9-not reached [NR]) months. One-year OS after AVM was 52%. In PD-L1 positive patients, median PFS and OS were 6.4 (CI: 2.7 - NR) months and 13.4 (CI: 7.7 months - NR), respectively. CONCLUSION: AVM is associated with moderate AE rates. Despite similarities in baseline characteristics compared to trial-selected JAVELIN Bladder 100 mUC patients, AVM resulted in longer/similar PFS but significantly shorter OS in in real-world setting.

[Urinary diversion with or without simple cystectomy as a salvage option for benign diseases of the lower urinary tract]. / Harnableitungen mit oder ohne simple Zystektomie in der Salvage-Therapie benigner Erkrankungen des unteren Harntraktes.

Benign diseases of the lower urinary tract can occur as a result of oncological or neurological diseases or their respective therapies (e.g., surgery or radiation treatment) and can significantly reduce the quality of life for affected patients. Urinary diversion serves as a salvage option when all other therapeutic regimens have been carried out and proven unsuccessful. When selecting the suitable urinary diversion, a comprehensive clinical assessment of the patients is required in order to ensure long-term success. In some cases, a cutaneous, catheterizable pouch offers the last and only option for a long-term and definitive treatment of a patient's condition. Overall, a decreasing trend in the establishment of a continent urinary diversion is observed in Germany. Current data on benign indications for urinary diversion are limited. Therefore, further data collection and research are needed.

The first successful bone marrow transplantation in Vietnam for a young Vietnamese boy with chronic granulomatous disease: a case report.

Background: Chronic granulomatous disease (CGD) is an inborn error of immunity (IEI) disorder that results from defects in the respiratory burst activity in phagocytes, leading to the inability to kill bacterial and fungal microorganisms. CGD patients usually have a high incidence of morbidity such as infections and autoinflammatory diseases and a high mortality rate. Allogeneic bone marrow transplantation (BMT) is the only definitive cure for patients who suffer from CGD. Case presentation: We report the first transplant case of chronic granulomatous disease in Vietnam. A 25-month-old boy with X-linked CGD underwent bone marrow transplantation from his 5-year-old, full-matched human leukocyte antigen (HLA)-carrier sibling after myeloablative conditioning regimen with busulfan 5.1 mg/kg/day for 4 days, fludarabine 30 mg/m2/day for 5 days, and rATG (Grafalon-Fresenius) 10 mg/kg/day for 4 days. Neutrophil was engrafted on day 13 posttransplant, donor chimerism was 100% on day 30 with the dihydrorhodamine-1,2,3 (DHR 123) flow cytometric assay test that reached 38% of the normal 45 days posttransplant. Five months after transplant, the patient was free of infection with stable DHR 123 assay at 37%, and donor chimerism remained 100%. No sign of a graft-versus-host disease had been observed posttransplant. Conclusion: We suggest that bone marrow transplantation is a safe and effectual cure for CGD patients, especially for patients with HLA-identical siblings.

Clinical-functional characteristics of children with asthma and obstructive sleep apnea overlap associated with attention deficit hyperactivity disorder: A cross-sectional study.

Background: Asthma and obstructive sleep apnea (OSA) are common chronic respiratory disorders in children. The relationship between asthma and OSA is bidirectional; these conditions share multiple epidemiological risk factors. Untreated OSA may cause attention deficit hyperactivity disorder (ADHD) symptoms. This study aimed to assess the prevalence of ADHD in asthmatic children with OSA and the link between asthma control and lung function of children with asthma and OSA. Methods: A total of 96 children aged 6-15 years diagnosed with asthma, according to the Global Initiative for Asthma (GINA) 2020, were enrolled in this study. All demographic data, including age, gender, body mass index, asthma control status, therapy, the Vanderbilt ADHD Diagnostic Parent Rating Scale, lung function, and exhaled nitric oxide, were collected. In addition, home respiratory polygraphy was used to identify OSA in study subjects. Results: A total of 96 patients (8.4 ± 2.4 years) were included in the present study. OSA was identified in 60.4% of asthmatic children with a mean apnea-hypopnea index (AHI) of 3.5 ± 3.0 event/h. The inattentive ADHD subtype was significantly lower in the non-OSA asthmatic group than in the OSA asthmatic group (7.9 vs. 34.5%, p < 0.05). ADHD had a higher probability of presence (OR: 3.355; 95% CI: 1.271-8.859; p < 0.05) in the OSA group (AHI >1 event/h). Children with poorly controlled asthma had a significantly high risk of OSA (83.0 vs. 17.0%, p < 0.001) than children with well-controlled asthma. Allergic rhinitis increased the odds of having OSA in patients with asthma [OR: 8.217 (95% CI: 3.216-20.996); p < 0.05]. Conclusion: The prevalence of OSA is increased among poorly controlled asthma. ADHD may have a higher prevalence in children with OSA. Therefore, prompt diagnosis of OSA will lead to an accurate asthma control strategy in patients with asthma.

Deciphering the Molecular Machinery-Influence of sE-Cadherin on Tumorigenic Traits of Prostate Cancer Cells.

The serum level of soluble (s)E-cadherin is elevated in several malignancies, including prostate cancer (PCa). This study was designed to investigate the effects of sE-cadherin on the behavior of PCa cells in vitro, with the aim of identifying a potential therapeutic target. Growth as well as adhesive and motile behavior were evaluated in PC3, DU-145, and LNCaP cells. Flow cytometry was used to assess cell cycle phases and the surface expression of CD44 variants as well as α and ß integrins. Confocal microscopy was utilized to visualize the distribution of CD44 variants within the cells. Western blot was applied to investigate expression of α3 and ß1 integrins as well as cytoskeletal and adhesion proteins. Cell growth was significantly inhibited after exposure to 5 µg/mL sE-cadherin and was accompanied by a G0/G1-phase arrest. Adhesion of cells to collagen and fibronectin was mitigated, while motility was augmented. CD44v4, v5, and v7 expression was elevated while α3 and ß1 integrins were attenuated. Blocking integrin α3 reduced cell growth and adhesion to collagen but increased motility. sE-cadherin therefore appears to foster invasive tumor cell behavior, and targeting it might serve as a novel and innovative concept to treat advanced PCa.
