Effectiveness of Paxlovid in Reducing Severe COVID-19 and Mortality in High Risk Patients

alexandrossfakianakis shared this article with you from Inoreader Effectiveness of Paxlovid in Reducing Severe COVID-19 and Mortality in High Risk Patients via Clinical Infectious Diseases Advance Access Abstract Background Paxlovid was granted emergency use authorization for the treatment of mild to moderate COVID-19, based on the interim analysis of EPIC-HR trial. Paxlovid effectiveness needs to be assessed in a noncontrolled setting. In this study we used population-based real world data to evaluate the effectiveness of Paxlovid. Methods The database of the largest healthcare provider in Israel was used to identify all adults aged 18 years or older with first ever positive test for SARS-CoV-2 between January and February 2022, who were at high risk for severe COVID-19 and had no contraindications for Paxlovid use. Patients were included irrespective of their COVID-19 vaccination status. Cox hazard regression was used to estimate the 28 day HR for severe COVID-19 or mortality with Paxlovid examined as time-dependent variable. Results Overall, 180,351 eligible were included, of them only 4,737 (2.6%) were treated with Paxlovid , and 135,482 (75.1%) had adequate COVID-19 vaccination status. Both Paxlovid and adequate COVID-19 vaccination status were associated with significant decrease in the rate of severe COVID-19 or mortality with adjusted HR 0.54 (95% CI, 0.39-0.75) and 0.20 (95% CI, 0.17-0.22), respectively. Paxlovid appears to be more effective in older patients, immunosuppressed patients, and patients with underlying neurological or cardiovascular disease (interaction p-value <0.05 for all). No significant interaction was detected between Paxlovid treatment and COVID-19 vaccination status. Conclusions This study suggests that in the era of omicron and in real life setting Paxlovid is highly effective in reducing the risk of severe COVID-19 or mortality. View on Web

Novel technique to prevent or correct open‐mouth deformity after bilateral mandibular resection: Use of tensor fascia lata slings

alexandrossfakianakis shared this article with you from Inoreader Novel technique to prevent or correct open‐mouth deformity after bilateral mandibular resection: Use of tensor fascia lata slings via Head & Neck Abstract Open-mouth deformity after mandibular resection presents a challenge for surgeons and patients, contributing to significant functional and cosmetic morbidity. We present an innovative surgical technique to prevent or correct open-mouth deformity. Tensor fascia lata slings were utilized in combination with maxillomandibular fixation to surgically correct or prevent open-mouth deformity in four patients who had previously undergone mandibulectomy or at the time of a contralateral mandibulectomy following prior hemimandibulectomy and reconstruction. Two patients achieved favorable outcomes, including oral competence and improved resting jaw position, while open-mouth deformity could not be corrected for one patient. Another patient remains in the early postoperative period following a secondary procedure to correct open-mouth deformity. Open-mouth deformity is a functional/aesthetic problem that has not been addressed in the literature. Use of tensor fascia lata slings to suspend the mandible is a novel approach to the surgical management of open-mouth deformity. View on Web

Nonsuicidal self‐injury and rumination: A meta‐analysis

alexandrossfakianakis shared this article with you from Inoreader Nonsuicidal self‐injury and rumination: A meta‐analysis via Journal of Clinical Psychology Abstract Trait rumination is the tendency to overthink and focus on negative emotions and events and is related to a number of psychological disorders and maladaptive behaviors including nonsuicidal self-injury (NSSI). The purpose of this study was to conduct a meta-analysis of the relationship between trait rumination and NSSI behaviors. Results from 60 samples showed small effect sizes between trait rumination and NSSI engagement, NSSI frequency, and the number of methods used to self-injure in cross-sectional samples. Results from 13 samples showed small effect sizes between trait rumination and NSSI engagement and NSSI frequency in longitudinal samples. Moderator analyses indicated that this relationship is similar whether the type of rumination is depressive or not and is generally consistent across different ages, genders, and ethnicities. These results help clarify the role of trait rumination as a risk factor for NSSI. View on Web

Comparison of Sinus Distribution between Nasal irrigation and Nasal spray Using Fluorescein‐labeled in patients with Chronic Rhinosinusitis: A Randomized Clinical Trial

alexandrossfakianakis shared this article with you from Inoreader Comparison of Sinus Distribution between Nasal irrigation and Nasal spray Using Fluorescein‐labeled in patients with Chronic Rhinosinusitis: A Randomized Clinical Trial via Clinical Otolaryngology Abstract Objective This study aims to compare the potential sinus distribution between high-volume nasal irrigation and nasal spray in chronic rhinosinusitis (CRS) patients who have not undergone sinus surgery. Design and Setting A randomized clinical study was conducted at the Otolaryngology-Head & Neck Surgery Department, Ramathibodi Hospital, Faculty of Medicine, Mahidol University. Participants Forty patients undergoing endoscopic sinus surgery (ESS) for CRS. Thirty-eight patients met the inclusion criteria and were randomly assigned to receive nasal irrigation or nasal spray mixed with fluorescein sodium preoperatively. Main outcome measures The primary outcome was the mean difference in the staining score of fluorescein in all sinuses between the two groups. Results The total fluorescein staining score for all sinuses in the nasal irrigation group was significantly higher than the score from the nasal spray group, with a mean difference score of 2.90, 95%CI: 1.22-4.58, p-value 0.001. The most significantly affected sinuses were the maxillary and the anterior ethmoid sinuses, while the frontal and sphenoid sinuses had only minimal staining from both techniques. Conclusion Nasal irrigation is a potential route to deliver drugs into the sinus in unoperated CRS patients. However, it is not considered a superior method to nasal spray at the most challenging anatomical areas, i.e., the frontal and sphenoid sinuses. View on Web

DNA methylation profiling of central nervous system hemangioblastomas identifies two distinct subgroups

alexandrossfakianakis shared this article with you from Inoreader DNA methylation profiling of central nervous system hemangioblastomas identifies two distinct subgroups via Brain Pathology Abstract Hemangioblastomas (HBs) of the central nervous system are highly vascular neoplasms that occur sporadically or as a manifestation of von Hippel–Lindau (VHL) disease. Despite their benign nature, HBs are clinically heterogeneous and can be associated with significant morbidity due to mass effects of peritumoral cysts or tumor progression. Underlying molecular factors involved in HB tumor biology remain elusive. We investigated genome-wide DNA methylation profiles and clinical and histopathological features in a series of 47 HBs from 42 patients, including 28 individuals with VHL disease. Thirty tumors occurred in the cerebellum, 8 in the brainstem and 8 HBs were of spinal location, while 1 HB was located in the cerebrum. Histologically, 12 HBs (26%) belonged to the cellular subtype and exclusively occurred in the cerebellum, whereas 35 HBs were reticular (74%). Unsupervised clustering and dimensionality reduction of DNA methylation profiles revealed two distinct subgroups. Methyl ation cluster 1 comprised 30 HBs of mainly cerebellar location (29/30, 97%), whereas methylation cluster 2 contained 17 HBs predominantly located in non-cerebellar compartments (16/17, 94%). The sum of chromosomal regions being affected by copy-number alterations was significantly higher in methylation cluster 1 compared to cluster 2 (mean 262 vs. 109 Mb, p = 0.001). Of note, loss of chromosome 6 occurred in 9/30 tumors (30%) of methylation cluster 1 and was not observed in cluster 2 tumors (p = 0.01). No relevant methylation differences between sporadic and VHL-related HBs or cystic and non-cystic HBs could be detected. Deconvolution of the bulk DNA methylation profiles revealed four methylation components that were associated with the two methylation clusters suggesting cluster-specific cell-type compositions. In conclusion, methylation profiling of HBs reveals 2 distinct subgroups that mainly associate with anatomical location, cytogenetic profiles and differ ences in cell type composition, potentially reflecting different cells of origin.

Mechanistic and biologically based models in epidemiology; a powerful underutilized tool

alexandrossfakianakis shared this article with you from Inoreader Mechanistic and biologically based models in epidemiology; a powerful underutilized tool via American Journal of Epidemiology - Advance Access Abstract Mechanistic and biologically based mathematical models of chronic and behavioral disease processes aim to capture the main mechanistic or biological features of the disease development, and to connect these with epidemiological outcomes. These approaches have a long history in epidemiological research and are complementary to traditional epidemiological or statistical approaches to investigate the role of risk factor exposures on disease risk.In the article by Simonetto et al. (Am J Epidemiol. XXXX;XXX(XX):XXXX–XXXX)), the authors present a mechanistic, process-oriented, model to investigate the role of smoking, hypertension and dyslipidemia on the development of atherosclerotic lesions and their progression to myocardial infarction (MI). Their approach builds on and brings to cardiovascular disease the ideas and perspectives of earlier mechanistic and biologically based models for the epidemiology of cancer and other chronic diseases, providin g important insights into the mechanisms and epidemiology of smoking related MI.We argue that although mechanistic modeling approaches have demonstrated their value and place in epidemiology, they are highly underutilized. We call for efforts to grow mechanistic and biologically based modeling research, expertise and awareness in epidemiology, including the development of training and collaboration opportunities to attract more students and researchers from STEM areas into the epidemiology field.
