Ryanodine strongly reduces CT frequency in imOLC processes. Ouabain, an antagonist of Na+, K+-ATPase (NKA), applied at low concentration increases CT frequency, while KB-R7943, a blocker of reverse mode of Na+, Ca2+ exchanger (NCX), decreases CT frequency. We suggest that local RyR-NCX-(NKA?) interaction might underlie the generation of CTs in imOLC in the absence of neurons, and this activity influences oligodendrocyte maturation.Background Although qualitative studies have been conducted to identify barriers and facilitators that influence the pain management of older adults with dementia, as far as we know, only a very recent study (Andrews et al., 2019) has used participatory action research (PAR) as a methodology for studying pain management. It allows nurses to examine and improve their practice based on their realities and within their context. Aim To reflect on nursing practice and identify facilitators and barriers in the management of pain in older adults with dementia and to propose actions for improvement. Design We used qualitative participatory action research. Participants/settings Ten nurses from the geriatric acute care unit of a university hospital in Spain were recruited through convenience sampling. Methods Data were generated through a written questionnaire and three focus groups. Results One of the main facilitators the participants identified was professional experience. The main barriers they identified were lack of knowledge and skills and lack of time. The participants proposed two main improvements (1) a training program consisting of three courses (pain evaluation and management, dementia and pain, and pharmacology) and (2) the creation of a specific register for nurses to record patients' pain. Conclusions Involving nurses directly in research on their practices can result in precise proposals for improvements based on their needs and oriented toward improving the quality of care.

Given real-world limitations in programmed death-ligand 1 (PD-L1) testing, concordance studies between PD-L1 assays are needed. We undertook comparisons of Dako 28-8 and Ventana SP142 assays in mRCC and Dako 22C3 and Ventana SP263 assays in mUC. Patients and methods Thirty-two patients with mRCC and 18 patients with mUC who had received immune checkpoint inhibitor therapy were identified. Formalin-fixed paraffin-embedded tumor samples for patients with mRCC were evaluated with Dako 28-8 and Ventana SP142 PD-L1 immunohistochemistry assays. For patients with mUC, formalin-fixed paraffin-embedded tumor samples were evaluated with Dako 22C3 and Ventana SP263 PD-L1 immunohistochemistry assays. Results The majority (29/32; 91%) of mRCC cases were concordant between assays. The majority (17/18; 94%) of mUC cases were also concordant between assays. Conclusions There was strong concordance between PD-L1 assays chosen for comparison in both mRCC and mUC, with similar performance characteristics. One limitation is the small number of cases in this study; larger comparison studies are needed for this biomarker in mRCC and mUC.Background Tyrosine kinase inhibitor-based adjuvant therapy showed no survival benefits for patients with high-risk nonmetastatic renal cell carcinoma (nmRCC). Five randomized immune-oncology checkpoint inhibitor trials are ongoing. We assessed the effect of stage, grade, and histologic type on cancer-specific mortality (CSM) in candidates for 1 of the 4 North American ongoing immune-oncology checkpoint inhibitor trials of high-risk nmRCC. Patients and methods From the Surveillance, Epidemiology, and End Results database (2001-2015), we identified patients who had undergone surgery for nmRCC and had met the inclusion criteria for the PROSPER RCC (nivolumab in treating patients with localized kidney cancer undergoing nephrectomy), CheckMate 914 (a study comparing the combination of nivolumab and ipilimumab versus placebo in participants with localized renal cell carcinoma), KEYNOTE-564 [safety and efficacy study of pembrolizumab (MK-3475) as monotherapy in the adjuvant treatment of renal cell carcinoma post neeatures (HR, 5.5; P less then .001). Among the 4 random samples, the difference in the qualifying criteria resulted in the greatest versus progressively lower CSM rates in the IMmotion010, KEYNOTE-564, CheckMate 914, and PROSPER RCC trials, respectively (P less then .001). Conclusions Our findings indicate that participation in adjuvant immunotherapy trials should be predominantly encouraged for patients with high-grade stage T3, T4, and N1 and patients with any stage with sarcomatoid pathologic features.Purpose Marsupialization, designed to reduce the mandibular cyst volume, has continued to debated regarding its influence on the healing of the related bone cavity. The aim of the present study was to evaluate the 3-dimensional radiographic variation over time in mandibular odontogenic cystic lesions after marsupialization and assess the correlations between these variations and variables that can affect the procedure. Materials and methods We planned a retrospective cohort study. The predictor variables were the treatment duration, preoperative volume, patient age, histologic type, and number of preoperative residual bony walls. The outcomes variables were the postoperative volume reduction and the daily reduction rate calculated using computed tomography (CT) from before to after marsupialization using software designed for volumetric reconstruction and measurement of cyst-related bone defects. The descriptive and bivariate statistics were computerized, and the significance level was set at P = .05. Results The sample included 15 patients (12 men and 3 women; mean age, 51.6; range, 27 to 85 years) affected by keratocysts (n = 6), dentigerous cysts (n = 6), and radicular cysts (n = 3) who had undergone marsupialization. The median duration of marsupialization was 406 days (25th to 75th percentile, 276 to 519). The mean ± standard deviation (SD) pre- and postdecompression volumes were 6,908.27 ± 2,669.058 and 2,468.13 ± 1,343.517 mm3, respectively (P .05). Conclusions Marsupialization appears useful in improving the healing of cyst-related bone defects in mandibles, especially larger defects. Further studies with a wider sample size would add more knowledge to this topic.
