Adjuvant Radiation and Survival Following Surgical Resection of Sinonasal Adenocarcinoma

alexandrossfakianakis shared this article with you from Inoreader Adjuvant Radiation and Survival Following Surgical Resection of Sinonasal Adenocarcinoma via The Laryngoscope Sinonasal adenocarcinoma is a rare primary malignancy treated with surgical resection with or without adjuvant radiotherapy. In this study, we saw that radiation therapy may not have an attributable survival benefit. Objectives This study aims to investigate the utility of adjuvant radiation in patients who undergo surgical resection for the management of node-negative sinonasal adenocarcinoma (SNAC). Study Design Retrospective database review. Methods The 2004–2016 National Cancer Data Base (NCDB) was used to extract patients with surgically resected node-negative SNAC. Kaplan–Meier survival analysis and Cox-Proportional Hazards Modelling were used to analyze the impact of adjuvant radiation on overall survival (OS) following surgery. Results 349 patients with SNAC underwent surgical resection. Of these patients, 154 (44.1%) received adjuvant radiotherapy (RT). Although there was no significant difference in race, age, or sex of those receiving RT, those receiving RT have more advanced diseases and are more likely to have positive margins. Kaplan Meier analysis showed no significant difference in 5-year OS in patient who received adjuvant RT in comparison to those who underwent surgical resection alone (65.7% vs. 72.6%, respectively; p = 0.378). In addition, when looking at only patients with positive margins, 5-year OS still did not have a significant difference (73.8% vs. 61.6%, respectively; p = 0.101). Only patients with clinical AJCC T4 showed a statistically significant survival benefit with adjuvant RT (56.9% vs. 29.9%, respectively; p = 0.009). Conclusions Adjuvant RT does not appear to provide a significant survival benefit in patients with resected SNAC, with the exception of those with clinically AJCC T4 disease.

Prevalence of Apical Periodontitis in Patients with Autoimmune Diseases: A Case Control Study

alexandrossfakianakis shared this article with you from Inoreader Prevalence of Apical Periodontitis in Patients with Autoimmune Diseases: A Case Control Study via International Endodontic Journal Abstract Aim The purpose of this case-control study was to compare the prevalence of Apical Periodontitis (AP) in patients affected by Autoimmune Disorders (AD) [Inflammatory Bowel Disease (IBD), Rheumatoid Arthritis (RA), and Psoriasis (Ps)] with the prevalence of AP in subjects without AD. The prevalences of AP in patients taking biologic medications, conventional medications and no medication were also compared. Methodology 89 patients (2,145 teeth) with AD were investigated and the control group included 89 patients (2,329 teeth) with no systemic diseases. Full dental panoramic tomograms were used to determine the periapical status of the teeth. Additional variables investigated included patient's socio-demographic characteristics, medications taken by AD patients, the Decayed, Missing, and Filled Teeth (DMFT) index. The chi-square test and logistic regression analysis were used to evaluate the correlation between AD and AP. P-values lower than 0.05 were considered to be statistically significant. Results The prevalence of AP was 89.9% in AD patients and 74.2% in control subjects (odds ratio [OR]=3.75, p=0.015). The DMFT score was found to be significantly higher in the AD group (p=0.004). Patients with RA had the highest risk of being affected by AP, whereas those with IBD had the lowest risk. Multiple binary logistic regression analysis indicated that the teeth of AD patients who were not taking any medication or were being treated with biologic Disease Modifying Anti-Rheumatic Drugs (bDMARDs) had a higher risk of being affected by AP than did the teeth of the control subjects (OR=1.42 and OR=2.03 respectively; p=0.010). The teeth of patients taking conventional DMARDs (cDMARDs) were less affected by AP compared with those of patients taking bDMARDs. Conclusions Patients with AD, whether treated or not with biologic medications, showed a higher prevalence of AP than did those in the control group. The DMFT index score, which was higher in AD patients compared with controls was identified as a significant predictor of AP prevalence. View on Web

Estimating the effect of physical activity on cognitive function within the UK Biobank cohort

alexandrossfakianakis shared this article with you from Inoreader Estimating the effect of physical activity on cognitive function within the UK Biobank cohort via International Journal of Epidemiology - Advance Access Abstract Background Physical activity (PA) has been associated with benefits for cognitive function (CF), but previous estimates of the strength of this relationship may have been biased due to limitations in statistical modelling practices that are common among observational studies. We aimed to address this by using a rigorously constructed conceptual causal model to guide an empirical analysis estimating the effect of PA on CF in the UK Biobank cohort of middle-aged and older adults. Methods This study analysed a subsample of 334 227 adults from the UK Biobank prospective cohort study. PA was measured subjectively by self-report and by device using accelerometry, and CF was measured using objective cognitive tests. Composite CF measures were derived to represent general and domain-specific performance. Effect coefficients were estimated using regression models, adjusting for a wide range of confounders specified by the assumed caus al model, including genetic risk factors, and relevant health, sociodemographic and behavioural variables from across the lifespan. Results Results indicated very small effect sizes (standardized mean difference estimates all <0.01) of inconsistent direction, for both cross-sectional and longitudinal analyses. Conclusions The expected protective effect of PA on CF was not observed. This may reflect selection bias within UK Biobank, or the relatively young age of the sample at follow-up. View on Web

Usefulness of dried blood spot samples for monitoring hepatitis C treatment outcome and reinfection among people who inject drugs in a test‐and‐treat program

alexandrossfakianakis shared this article with you from Inoreader Usefulness of dried blood spot samples for monitoring hepatitis C treatment outcome and reinfection among people who inject drugs in a test‐and‐treat program via Journal of Medical Virology Abstract Background Dried blood spots (DBS) are a reliable tool to diagnose viremic HCV infection. We evaluated the clinical performance of a DBS-based molecular assay for the assessment of cure and reinfection after on-site treatment at a harm reduction centre (HRC). Genotyping from DBS samples was also assessed to discriminate reinfection from treatment failure. Methods People who inject drugs (PWID) from an ongoing microelimination pilot at the largest HRC in Barcelona were included in the study. HCV-RNA detection from DBS collected after treatment (with follow-up at 12, 36 and 60 weeks) was compared with a molecular point-of-care test using finger-stick blood (GeneXpert). Baseline and follow-up DBS samples were genotyped by NS5B sequencing or commercial real-time PCR. Results Among treated patients, 193 follow-up DBS samples were tested. The DBS-based assay showed 100% specificity (129/129), and sensitivity ranged from 84.4% to 96.1% according to different viral load cut-offs (from detectable to 3000 IU/mL). Sensitivity as test of cure (follow-up 12) ranged from 85.1 to 97.4%. Among the 64 patients with recurrent viremia, 10.9% had low viral loads (≤1000 IU/mL); HCV genotyping allowed us to classify 73.5% of viremic cases either as reinfection or as treatment failure. Conclusions DBS samples are useful to assess cure and differentiate reinfection from relapse after HCV antiviral treatment in the real world, facilitating decentralization of treatment and post-treatment follow-up in PWID. However, a fraction of patients presented with low viral loads, limiting viremia detection and genotyping in DBS and, therefore, repeat testing is recommended. This article is protected by copyright.

The AUGIS Survival Predictor: Prediction of Long-Term and Conditional Survival After Esophagectomy Using Random Survival Forests

alexandrossfakianakis shared this article with you from Inoreader The AUGIS Survival Predictor: Prediction of Long-Term and Conditional Survival After Esophagectomy Using Random Survival Forests via Annals of Surgery - Most Popular Articles Objective: The aim of this study was to develop a predictive model for overall survival after esophagectomy using pre/postoperative clinical data and machine learning. Summary Background Data: For patients with esophageal cancer, accurately predicting long-term survival after esophagectomy is challenging. This study investigated survival prediction after esophagectomy using a Random Survival Forest (RSF) model derived from routine data from a large, well-curated, national dataset. Methods: Patients diagnosed with esophageal adenocarcinoma or squamous cell carcinoma between 2012 and 2018 in England and Wales who underwent an esophagectomy were included. Prediction models for overall survival were developed using the RSF method and Cox regression from 41 patient and disease characteristics. Calibration and discrimination (time-dependent area under the curve) were validated internally using bootstrap resampling. Results: The study analyzed 6399 patients, with 2625 deaths during follow-up. Median follow-up was 41 months. Overall survival was 47.1% at 5 years. The final RSF model included 14 variables and had excellent discrimination with a 5-year time-dependent area under the receiver operator curve of 83.9% [95% confidence interval (CI) 82.6%–84.9%], compared to 82.3% (95% CI 81.1%—83.3%) for the Cox model. The most important variables were lymph node involvement, pT stage, circumferential resection margin involvement (tumor at View on Web

High C‐reactive protein to lymphocyte ratio predicts mortality outcomes of patients with severe fever suffering from thrombocytopenia syndrome: a multi‐centre study in China.

alexandrossfakianakis shared this article with you from Inoreader High C‐reactive protein to lymphocyte ratio predicts mortality outcomes of patients with severe fever suffering from thrombocytopenia syndrome: a multi‐centre study in China. via Journal of Medical Virology Abstracts Severe fever with thrombocytopenia syndrome (SFTS) is a life-threatening infectious disease caused by the SFTS virus (SFTSV). This study aimed to evaluate the predictive power of C-reactive protein to lymphocyte ratio (CLR) and establish an early-warning model for SFTS mortality. We retrospectively analysed hospitalised SFTS patients in six clinical centres from May 2011 to May 2022. The efficacy of CLR prediction was evaluated by the receiver operating characteristic (ROC) analysis. A nomogram was established and validated. 882 SFTS patients (median age 64 years, 48.5% male) were enrolled in this study, with a mortality rate of 17.8%. The area under the ROC curve (AUC) of CLR was 0.878 (95% CI: 0.850-0.903, P<0.001), which demonstrates high predictive strength. The least absolute shrinkage and selection operator (LASSO) regression selected seven potential predictors. Multivariate logistic regression analysis determined three independent risk factors, including CLR, to construc t the nomogram. The performance of the nomogram displayed excellent discrimination and calibration, with significant net benefits in clinical uses. CLR is a brand-new predictor for SFTS mortality. The nomogram based on CLR can serve as a convenient tool for physicians to identify critical SFTS cases in clinical practice. This article is protected by copyright. All rights reserved. View on Web

HBsAg (‐)/HBsAb (‐)/HBeAg (‐)/HBeAb (+)/HBcAb (+) predicts a high risk of hepatitis B reactivation in patients with B‐cell lymphoma receiving rituximab based immunochemotherapy

alexandrossfakianakis shared this article with you from Inoreader HBsAg (‐)/HBsAb (‐)/HBeAg (‐)/HBeAb (+)/HBcAb (+) predicts a high risk of hepatitis B reactivation in patients with B‐cell lymphoma receiving rituximab based immunochemotherapy via Journal of Medical Virology Abstract Patterns of hepatitis B virus reactivation (HBV-R) in HBsAg (-)/HBcAb (+) patients with B-cell non-Hodgkin lymphoma (NHL) receiving rituximab based immunochemotherapy have not been well described. The retrospective study included 222 HBsAg (-)/HBcAb (+) NHL patients as training cohort and 127 cases as validation cohort. The incidence of HBV-R in HBsAg (-)/HBcAb (+) B-cell NHL patients was 6.3% (14/222), of which that in HBsAg (-)/HBsAb (-)/HBeAg (-)/HBeAb (+)/HBcAb (+) population was 23.7% (9/38). Multivariate analysis showed that HBsAg (-)/HBsAb (-)/HBeAg (-)/HBeAb (+)/HBcAb (+) correlated with a high risk of HBV-R in B-cell lymphoma patients (training phase HR, 10.123; 95% CI, 3.389 to 30.239; P < 0.001; validation phase HR, 18.619; 95% CI, 1.684 to 205.906; P = 0.017; combined HR, 12.264; 95% CI, 4.529-33.207; P < 0.001). The mortality rate of HBsAg (-)/HBcAb (+) B-cell NHL caused by HBV-R was 14.3% (2/14) while that for HBV reactivated HBsAg (-)/HBsAb (-)/HBeAg (-)/HBeAb (+)/HBcAb (+) population was up to 44.4% (4/9). As a high incidence of HBV-R and high mortality after HBV-R was found in HBsAg (-)/HBsAb (-)/HBcAb (+)/HBeAg (-)/HBeAb (+) patients with B-cell NHL receiving rituximab based immunochemotherapy, prophylactic antiviral therapy is recommended for these patients.
