Abstract Background: COVID-19 hospitalization definitions do not include a disease severity assessment. Thus, we sought to identify a simple and objective mechanism for identifying hospitalized severe cases and to measure the impact of vaccination on trends. Methods: All admissions to a Veterans Affairs (VA) hospital, where routine screening is recommended, between 3/1/2020-11/22/2021 with SARS-CoV-2 were included. Moderate-to-severe COVID-19 was defined as any oxygen supplementation or any SpO2 <94% between one day before and two weeks after the positive SARS-CoV-2 test. Admissions with moderate-to-severe disease were divided by the total number of admissions, and the proportion of admissions with moderate-to-severe COVID-19 was modelled using a penalized spline in a Poisson regression and stratified by vaccination status. Dexamethasone receipt and its correlation with moderate-to-severe cases was also assessed. Results: Among 67,025 admissions with SARS-CoV-2, the proportion with hypoxemia or supplemental oxygen fell from 64% prior to vaccine availability to 56% by November 2021, driven in part by lower rates in vaccinated patients (vaccinated, 52% versus unvaccinated, 58%). The proportion of cases of moderate-to-severe disease identified using SpO2 levels and oxygen supplementation was highly correlated with dexamethasone receipt (correlation coefficient, 0.95), and increased after 7/1/2021, concurrent with delta variant predominance. Conclusions: A simple and objective definition of COVID-19 hospitalizations using SpO2 levels and oxygen supplementation can be used to track pandemic severity. This metric could be used to identify risk factors for severe breakthrough infections, to guide clinical treatment algorithms, and to detect trends in changes in vaccine effectiveness over time and against new variants.

Abstract Objectives: The study aims to evaluate therapeutic strategies in the management of craniospinal tumours in pregnant patients and the factors that influence the management along with their influence on maternal & foetal outcomes. Materials and Methods:A retrospective single-centre cohort study was performed at a tertiary neurosurgical referral centre. Pregnant patients referred to neuro-oncology multidisciplinary meeting (MDM) with craniospinal tumour were included. Ten-year patient data were collected from hospital records and neuro-oncology MDM outcomes. A systematic review was performed on the available literature in PubMed as per PRISMA guidelines. Results:Thirty-three patients were identified with a mean age of 31 years. 91%(n=30) had cranial lesions and 9%(n=3) had spinal lesions. Most of the patients had WHO Grade I/II tumours. 33.3% underwent surgery when pregnant whilst in 24.2% this was deferred until after the due date. 27.2% patients did not require surgical intervention and were followed up with serial imaging in the MDM. Left Lateral/park bench position was the preferred position for the spinal and posterior fossa lesions. Systematic review identified 26 eligible articles. Treatment algorithms are proposed addressing the therapeutic strategy for management of cranio-spinal tumours during pregnancy and the challenges for maternal and foetal outcomes were tabulated. Conclusions:Craniospinal tumours presenting in pregnancy are challenging. The surgical management needs to be tailored individually and as part of a multidisciplinary team approach. Maternal and foetal outcomes are to be considered during patient counselling.

Background: People experiencing homelessness are disproportionately affected by hepatitis C virus (HCV) and can face specific barriers to care. Simple treatment algorithms could increase linkage to care in this population. Methods: This retrospective real-world analysis pooling data from 15 clinical cohorts evaluated effectiveness of a once-daily sofosbuvir/velpatasvir (SOF/VEL) regimen in HCV-infected people experiencing homelessness. The primary outcome was sustained virological response (SVR) in the effectiveness population (patients with confirmed SVR status). Secondary outcomes included reasons for not achieving SVR, adherence and time between diagnosis and SOF/VEL treatment start. Results: Of 153 patients treated with SOF/VEL for 12 weeks without ribavirin, SVR was 100% in the effectiveness population (n = 122), irrespective of various baseline factors including active injecting drug use and presence of mental health disorders. Conclusion: HCV-infected people experiencing homelessness can successfully be treated with SOF/VEL. SOF/VEL enables implementation of simple treatment algorithms and can support test-and-treat strategies through rapid treatment starts and minimal monitoring.

Emergency conditions are very life-threatening situations and require fast actions and immediate intervention from medical stuff. For young doctors without extensive experience in the treatment of these important diseases, it is very crucial to know and timely apply modern treatment algorithms. Simulation medical scenarios are a good approach and can help to improve knowledge and practical skills. Authors provide frequent trainigs for students and interns for emergency medical conditions according to world standards and University syllabus. The main idea is to create new and improve old practical skills and competencies for students and interns.

Undifferentiated soft tissue sarcomas (UDSTS ) are a group of mesenchymal tumors that remain a diagnostic challenge due to their morphologic heterogeneity and unclear histologic origin (Peters et al. 2015b). In this case report, we present the first multi-omics molecular signature for a BCOR-CCNB3 sarcoma (BCS) that includes mutation analysis, gene expression, DNA methylation, and mi-RNA expression. We identify a paucity of additional mutations in this tumor and detail that there is significant dysregulation of gene expression of epigeneic remodeling agents including key members of the PRC, Sin3A/3b, NuRD, and NcoR/SMRT complexes and the DNA methyltransferases DNMT1, DNMT3a, and DNMT3b. This is accompanied by significant DNA methylation changes and dysregulation of multiple miRNA with known links to tumorigenesis. This study significantly increases our understanding of the BCOR effects on fusion positive undifferentiated sarcomas at both the genomic and epigenomic level and suggests that as better-tailored and more refined treatment algorithms continue to evolve, epigenetic modifying agents should be further evaluated for their efficacy against these tumors.

Lymphomas encompass a diverse group of malignant lymphoid neoplasms. Over recent years much scientific effort has been undertaken to identify and understand molecular changes in lymphomas, resulting in a wide range of genetic alterations that have been reported across all types of lymphomas. As many of these changes are now incorporated into the World Health Organization’s defined criteria for the diagnostic evaluation of patients with lymphoid neoplasms, their accurate identification is crucial. Even if many alterations are not routinely evaluated in daily clinical practice, they may still have implications in risk stratification, treatment, prognosis or disease monitoring. Moreover, some alterations can be used for targeted treatment. Therefore, these advances in lymphoma molecular diagnostics in some cases have led to changes in treatment algorithms. Here, we give an overview of and discuss advances in molecular techniques in current clinical practice, as well as highlight some of them in a clinical context.

Treatment algorithms in the treatment of advanced non-small cell lung cancer (NSCLC) continue to evolve as new therapeutics show positive efficacy improvements. This review article summarizes the data for the use of immunotherapy for treatment in first-line stage IV NSCLC, organized by the following four sections: single-agent immunotherapy, immunotherapy and chemotherapy, dual immunotherapy, and dual immunotherapy and chemotherapy. The results are summarized and tabulated. Finally, application of the trial data is illustrated in four clinical scenarios depending on the programmed death-ligand 1 (PD-L1) expression levels. Single checkpoint inhibitors have become an easy and excellent treatment in patients whose tumors have high PD-L1 expression. Adding chemotherapy to immunotherapy benefits our patients. Immunotherapy, with or without chemotherapy, is now the standard of care in the first-line setting in patients without EGFR, ALK, or ROS driver mutations.

Background: Neuromuscular conditions account for 1/3 of IVIg use in BC and costs over $10 million annually. Since 2013, the BC Neuromuscular Review Panel has developed diagnostic and treatment algorithms for the use of IVIg. A framework was created to review high dose and chronic users. Methods: Utilizing Central Transfusion Registry data, all patients treated with IVIg for approved neuromuscular conditions (CIDP, MG, MMN) since April 1, 2013 were identified. Annual cohorts for patients using higher than usual dose and chronic use (>3 years) were established, and evaluated annually. Patient specific recommendations were made. Results: The initial cohort identified 38 high users of 377 patients receiving IVIg. 27 appropriate, 9 “not appropriate”. Subsequent cohorts showed a decrease in number of patients receiving inappropriate IVIg doses. In BC there has been a 36% increase in neuromuscular patients treated with IVIg (377 in 2013/14 to 512 in 2016/17). Despite this, IVIg the program has effectively reduced the annual grams/patient from 516 gm/patient in 2013/14 to 489 gm/patient in 2016/17. Conclusions: The BC Neuromuscular IVIg Review confirms that the majority of IVIg use is appropriate. Following yearly cohorts of chronic and high dose users helps optimize IVIg use, which may lead to improved patient care.
