2% (95% CI 79.0%-92.5%), and the mean peri-implant bone loss was 1.01 ± 0.77 mm (95% CI 0.85-1.16 mm). The prosthesis survival rate was 96.6% (95% CI 82.2%-99.9%). The OHIP-20 and VAS scores both improved significantly from baseline to 1 year (p less then .001). Conclusion The implant survival rate was lower compared to the literature for the upper maxilla. Despite the encountered problems, PROMs showed significant improvement with the implant overdenture retained by 4 unsplinted implants compared to conventional dentures.Objectives To identify the association between cording and breast cancer-related lymphedema (BCRL); describe time course, location, symptoms and functional impairments. Methods A total of 1181 patients were prospectively screened for BCRL after breast cancer (BC) surgery, including patient-reported outcome measures (4193) and perometric arm volume measurements (BCRL defined as relative or weight-adjusted volume change [RVC or WAC] ≥10% ≥3 months postoperatively). Results A total of 374/1181 patients (31.7%) reported cording first a median of 4.5 months postoperatively, and were more likely to have body mass index less than 30 kg/m2 ; be less than 55 years of age; have had mastectomy, axillary lymph node dissection, regional lymph node radiation, neoadjuvant chemotherapy (all P less then .001), or RVC/WAC ≥10% (P = .002). Patients who reported cording had 2.4 times the odds of developing BCRL compared to those who did not (odds ratio = 2.40; 95% confidence interval = 1.40-4.11; P = .002), and most frequently reported these symptoms tenderness (61.2%), aching (60.7%), and firmness/tightness (59.8%). On multivariable analysis, cording was significantly correlated with functional difficulty for 17 actions. Conclusions Patients frequently present with cording, potentially months after BC surgery. Risk factors for and symptoms of cording are identified, and treatment is recommended. Patients reporting cording are at higher risk of BCRL, therefore, cording should be incorporated into BCRL risk stratification.Background The majority of patients with non-small cell lung cancer (NSCLC) harboring activating epidermal growth factor receptor (EGFR) mutations respond well to osimertinib (AZD9291), a third-generation, mutation-selective EGFR inhibitor. The current study focuses on determining whether targeting MEK/ERK signaling prevents or delays the development of acquired resistance to osimertinib. Methods Drug effects on cell survival were determined by measuring cell number alterations. Apoptosis was assessed with flow cytometry for the detection of annexin V-positive cells and with Western blotting for protein cleavage. Alterations of proteins in cells were detected with Western blotting. Drug effects on delaying the emergence of osimertinib resistance were evaluated with colony formation in vitro and xenografts in nude mice in vivo. Results Osimertinib combined with an MEK or ERK inhibitor synergistically decreased cell survival with enhanced induction of apoptosis in EGFR-mutant NSCLC cells but not in EGFR wild-type NSCLC cells. These combinations were also very effective in killing cell clones with primary intrinsic resistance to osimertinib. Continuous and intermittent pharmacologic inhibition of MEK/ERK signaling delayed the emergence of osimertinib resistance both in vitro and in vivo. Conclusions These results provide strong preclinical evidence in support of targeting MEK/ERK signaling as a strategy for delaying or preventing acquired resistance to osimertinib in the clinic to improve the long-term therapeutic efficacy of osimertinib. From a clinical standpoint, the data support the evaluation of an intermittent treatment schedule of osimertinib in combination with an MEK or ERK inhibitor in patients with EGFR-mutated NSCLC.Background Clinical practice guidelines (CPGs) are evidence-based guidelines that serve as a standard of care in oncology practice, reimbursements, and quality improvement initiatives. To our knowledge, the extent of financial conflicts of interest (FCOIs) in National Comprehensive Cancer Network (NCCN) guidelines have not been systemically evaluated. The current study evaluated the extent of FCOIs in the NCCN CPGs for the most common malignancies in the United States. Methods The authors examined the latest 2019 versions of the NCCN CPGs for the 10 most common cancers by incidence in the United States. Using disclosure lists, they catalogued the FCOIs for the panelists under various categories outlined in the CPG. The authors also tabulated the companies and institutions involved in each panel disclosure. [https://www.selleckchem.com/products/bi-3812.html BI-3812 price] An "episode" describes 1 instance of participation of a panelist in 1 company in 1 category of each guideline. "Affiliation" describes an industrial, commercial, or institutional affiliation reported by a pan, 6.4 episodes). The chairs and/or vice chairs of CPGs for uterine cancer, pancreatic cancer, melanoma, and prostate cancer were not found to have any FCOIs. Conclusions FCOIs are very prevalent among NCCN CPG panelists. In nearly one-half of the CPGs, the majority of the panelists had at least 1 FCOI. Greater than one-half of the CPG chairs and/or vice chairs reported multiple FCOIs. Further research studies are necessary to determine the impact of these FCOIs.Early life stress (ELS) is defined as a short or chronic period of trauma, environmental or social deprivation, which can affect different neurochemical and behavioral patterns during adulthood. Zebrafish (Danio rerio) have been widely used as a model system to understand human neurodevelopmental disorders and display translationally relevant behavioral and stress-regulating systems. In this study, we aimed to investigate the effects of moderate ELS by exposing young animals (6-weeks postfertilization), for 3 consecutive days, to three stressors, and analyzing the impact of this on adult zebrafish behavior (16-week postfertilization). The ELS impact in adults was assessed through analysis of performance on tests of unconditioned memory (free movement pattern Y-maze test), exploratory and anxiety-related task (novel tank diving test), and social cohesion (shoaling test). Here, we show for the first time that moderate ELS increases the number of alternations in turn-direction compared to repetitions in the unconditioned Y-maze task, suggesting increased working memory, but has no effect on shoal cohesion, locomotor profile, or anxiety-like behavior. Overall, our data suggest that moderate ELS may be linked to adaptive flexibility which contributes to build "resilience" in adult zebrafish by improving working memory performance.Noninvasive wearable devices have great potential to aid the management of epilepsy, but these devices must have robust signal quality, and patients must be willing to wear them for long periods of time. Automated machine learning classification of wearable biosensor signals requires quantitative measures of signal quality to automatically reject poor-quality or corrupt data segments. In this study, commercially available wearable sensors were placed on patients with epilepsy undergoing in-hospital or in-home electroencephalographic (EEG) monitoring, and healthy volunteers. Empatica E4 and Biovotion Everion were used to record accelerometry (ACC), photoplethysmography (PPG), and electrodermal activity (EDA). Byteflies Sensor Dots were used to record ACC and PPG, the Activinsights GENEActiv watch to record ACC, and Epitel Epilog to record EEG data. PPG and EDA signals were recorded for multiple days, then epochs of high-quality, marginal-quality, or poor-quality data were visually identified by reviewers, and reviewer annotations were compared to automated signal quality measures. For ACC, the ratio of spectral power from 0.8 to 5 Hz to broadband power was used to separate good-quality signals from noise. For EDA, the rate of amplitude change and prevalence of sharp peaks significantly differentiated between good-quality data and noise. Spectral entropy was used to assess PPG and showed significant differences between good-, marginal-, and poor-quality signals. EEG data were evaluated using methods to identify a spectral noise cutoff frequency. Patients were asked to rate the usability and comfort of each device in several categories. Patients showed a significant preference for the wrist-worn devices, and the Empatica E4 device was preferred most often. Current wearable devices can provide high-quality data and are acceptable for routine use, but continued development is needed to improve data quality, consistency, and management, as well as acceptability to patients.What is known and objective We investigated the elimination efficiency and pharmacokinetics (PK) parameters of vancomycin (VCM) in patients undergoing continuous haemodiafiltration (CHDF) using a polyethyleneimine-coated polyacrylonitrile membrane (AN69ST) for dosage adjustment. Methods We conducted a retrospective study of CHDF patients treated with VCM from December 2017 to August 2019. We calculated PK parameters of VCM and determined the 24-hour dose required to maintain the target trough concentration of VCM (VCM_trough ). Results and discussion The average (95% CI) volume of distribution and total clearance of VCM were 75.5 L (63.7-87.3 L) and 1.84 L/h (1.38-2.30 L/h), respectively, and the elimination rate constant and half-life were 0.026/h (0.017-0.034/h) and 31.2 h (22.8-39.5 h), respectively. The average AN69ST clearance of VCM (CL_CHDF ) was 0.69 L/h (0.52-0.86 L/h). The estimated average doses required to maintain VCM_trough of 10, 15 and 20 μg/mL were 623.1 mg (379.8-866.4 mg), 934.6 mg (569.7-1299.5 mg) and 1246.2 mg (759.6-1732.8 mg), respectively. What is new and conclusion The PK of VCM and CL_CHDF of AN69ST were clarified. These results suggest that it is possible to adjust the dose of VCM in using AN69ST, which efficiently removes cytokines, and contributes to improvement of serious infections.Purpose Image-Guided RadioTherapy (IGRT) improves tumor control but its intensive use may entrain late side effects caused by the additional imaging doses. There is a need to better quantify the additional imaging doses so they can be integrated in the therapeutic workflow. Currently, no dedicated software enables to compute patient-specific imaging doses on a wide range of systems and protocols. As a first step toward this objective, we propose a common methodology to model four different kV imaging systems used in radiotherapy (Varian's OBI, Elekta's XVI, Brainlab's ExacTrac, and Accuray's Cyberknife) using a new type of virtual source model based on Monte-Carlo calculations. Methods We first describe our method to build a simplified description of the photon output, or virtual source models (VSM), of each imaging system. Instead of being constructed using measurement data, as it is most commonly the case, our VSM is used as the summary of the phase-space files (PSF) resulting from a first Monte Carlo simulhe four imaging systems, VSMs were successfully validated against measurements in homogeneous phantoms, and are therefore ready to be used for future preclinical studies in heterogeneous or anthropomorphic phantoms. The cross system modeling methodology developed here should enable, later on, to estimate precisely and accurately patient-specific 3D dose maps delivered during a large range of kV-imaging procedures.
