MRI findings in six dogs with ependymoma of the brain and spinal cord.

There are few published descriptions of the MRI appearance of canine intracranial or spinal cord ependymoma. In this multicenter, retrospective, secondary analysis, case series study, three veterinary radiologists independently reviewed and recorded imaging characteristics of MRI studies in six dogs with histopathologically confirmed ependymoma (three intracranial and three spinal cord cases). A consensus was reached when there was disagreement on specific features.

Excess Opioid Medication and Variation in Prescribing Patterns Following Common Breast Plastic Surgeries.

Excess opioid prescribing has societal impacts including addiction, dependence, and misuse. This study aims to investigate prescribing patterns and self-reported patient experiences with opioid use, pain control, and disposal of unused medication following common breast surgeries. A total of 46 patients undergoing 5 breast procedures were identified during a predefined 14-week period.

Metformin Does not Affect Outcomes in Patients With Locally Advanced Rectal Cancer Treated With Neoadjuvant Therapy and Resection.

Introduction: There is emerging evidence that metformin may have a protective effect in patients with cancer. However, its current evidence in locally advanced rectal cancer (LARC) is inconclusive. We aim to assess the effect of metformin on long-term outcomes in patients with LARC who received neoadjuvant therapy and surgical resection.

Trends and Determinants of Location of Death Due to Colorectal Cancer in the United States : A Nationwide Study.

Background: Colorectal cancer (CRC) is the second leading cause of cancer-related mortality in the United States (US); however, there are limited data on location of death in patients who die from CRC. We examined the trends in location of death and determinants in patients dying from CRC in the US.

Methods: We utilized the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database to extract nationwide data on underlying cause of death as CRC.

Antibody-mediated NK cell activation as a correlate of immunity against influenza infection.

Antibodies play a critical role in protection against influenza; yet titers and viral neutralization represent incomplete correlates of immunity. Instead, the ability of antibodies to leverage the antiviral power of the innate immune system has been implicated in protection from and clearance of influenza infection. Here, post-hoc analysis of the humoral immune response to influenza is comprehensively profiled in a cohort of vaccinated older adults (65 + ) monitored for influenza infection during the 2012/2013 season in the United States (NCT: 01427309).

Primary esophageal melanoma: a case report.

Primary esophageal melanoma remains a rare entity with less than 350 case reports noted in the current literature. This diagnosis is associated with a poor prognosis and early detection and management remains fundamental. In this report, we examine the case of an 80-year-old female who presented with a 1-year course of progressive dysphagia and weight loss.

The "Claw Sign" may aid in axial localization in cases of peripherally located canine glioma on MRI.

The "claw sign" is a radiographic sign studied in human imaging to determine if a mass arises from a solid structure or organ versus a close adjacent location, resulting in distortion of the outline of an organ. We investigated its utility in characterizing MRI axial localization of peripherally located intracranial glioma versus meningioma, due to their overlap in MRI appearance. This retrospective, secondary analysis, cross-sectional study aimed to report the sensitivity, specificity, and inter- and intraobserver variabilities using kappa statistics, hypothesizing that the claw sign will have strong inter- and intraobserver agreement (κ > 0.

Patient Factors Affecting Inpatient Mortality Following Colorectal Cancer Resection.

Background: Our objective is to identify factors for inpatient death in patients undergoing resection for colorectal cancer (CRC).

Study Design: Unmatched 1:3 case-control study of surgically resected CRC at a tertiary care institution between 2004 and 2018. Variables for multivariate analysis were selected using tetrachoric correlation followed by a least absolute shrinkage and selection operator (LASSO) penalized regression model.

Colitis-Associated Colorectal Cancer Survival is Comparable to Sporadic Cases after Surgery: a Matched-Pair Analysis.

Background: Inflammatory bowel disease (IBD) confers an increased lifetime risk of colorectal cancer (CRC). The pathogenesis of colitis-associated CRC is considered distinct from sporadic CRC, but existing is mixed on long-term oncologic outcomes. This study aims to compare clinicopathological characteristics and survival between colitis-associated and sporadic CRC.

Methodological Quality of Open Access Compared to Traditional Journal Publications in the Plastic Surgery Literature.

Background: The methodological quality of open access studies has long been questioned due to increasing popularity and accessibility. The objective of this study is to compare the methodological quality of open access versus traditional journal publications in the plastic surgery literature.

Methods: Four traditional plastic surgery journals with their sister open access journals were chosen.

Pre-existing Fc profiles shape the evolution of neutralizing antibody breadth following influenza vaccination.

Under the ever-present threat of a pandemic influenza strain, the evolution of a broadly reactive, neutralizing, functional, humoral immune response may hold the key to protection against both circulating and emerging influenza strains. We apply a systems approach to profile hemagglutinin- and neuraminidase-specific humoral signatures that track with the evolution of broad immunity in a cohort of vaccinated individuals and validate these findings in a second longitudinal cohort. Multivariate analysis reveals the presence of a unique pre-existing Fcγ-receptor-binding antibody profile in individuals that evolved broadly reactive hemagglutination inhibition activity (HAI), marked by the presence of elevated levels of pre-existing FCGR2B-binding antibodies.

Social cognitive predictors of vaccination status, uptake and mitigation behaviors in the Canadian COVID-19 Experiences survey.

Emerging infectious diseases like COVID-19 will remain a concern for the foreseeable future, and determinants of vaccination and other mitigation behaviors are therefore critical to understand. Using data from the first two waves of the Canadian COVID-19 Experiences Survey (CCES; N = 1,958; 66.56 % female), we examined social cognitive predictors of vaccination status, transition to acceptance and mitigation behaviors in a population-representative sample.

Immunological and Clinico-Molecular Features of Tumor Border Configuration in Colorectal Cancer.

Introduction: Infiltrating tumor border configuration (ITBC) portends a poor prognosis compared with pushing tumor border configuration (PTBC) in colorectal cancer. The tumor and its surrounding immune microenvironment of tumor border configuration is not well-characterized. We aim to elucidate the differences in expression of molecular markers between the 2 groups using tissue microarray (TMA).

Internal Fixation of Finger Fractures: Field Sterility for Surgery and Earlier Removal of K-Wires Are Safe.

Field sterility for K-wire insertion outside the main operating room is much cheaper and greener (ie, there is less waste). It permits increased access to more affordable surgery because unnecessary sedation and full sterility are eliminated. Early pain-guided protected movement of K-wired finger fractures at 3 to 5 days leads to less stiffness.

Le déploiement de la surveillance épidémiologique automatisée du COVID-19 : une analyse comparée de la Corée du Sud et du Canada.

Governments across the world have deployed various surveillance devices to curb the COVID-19 pandemic. Based on literature research on two contrasting cases, South Korea and Canada, this study shows the influence of national context on deploying automated epidemiological surveillance of COVID-19. Beside highlighting food for thought regarding government management of a possible new health crisis, the study shows that civil society can contribute to informing public debate by bringing governments to be transparent in terms of automated epidemiological surveillance.

Molecular Basis of Extramural Vascular Invasion (EMVI) in Colorectal Carcinoma.

Background: Extramural vascular invasion (EMVI) is a known poor prognostic factor in colorectal carcinoma; however, its molecular basis has not been defined. This study aimed to assess the expression of molecular markers in EMVI positive colorectal carcinoma to understand their tumor microenvironment.

Methods: Immunohistochemistry was performed on tissue microarrays of surgically resected colorectal cancer specimens for immunological markers, and BRAFV600E mutation (and on the tissue blocks for mismatch repair proteins).

Differences in cigarette smoking quit attempts and cessation between adults who did and did not take up nicotine vaping: Findings from the ITC four country smoking and vaping surveys.

Introduction: There is mixed evidence as to whether nicotine vaping products (NVPs) can help adults who smoke transition away from cigarettes. This study investigated if self-reported attempts to quit smoking and smoking cessation, over a period of either 18 or 24 months, differed between respondents who initiated nicotine vaping versus those who did not. Outcome comparisons were made between those who: (1) initiated vaping vs.

Brain and behavior in health communication: The Canadian COVID-19 Experiences Project.

Background: Vaccine hesitancy and inconsistent mitigation behavior performance have been significant challenges throughout the COVID-19 pandemic. In Canada, despite relatively high vaccine availability and uptake, willingness to accept booster shots and maintain mitigation behaviors in the post-acute phase of COVID-19 remain uncertain. The aim of the Canadian COVID-19 Experiences Project (CCEP) is threefold: 1) to identify social-cognitive and neurocognitive predictors of mitigation behaviors, 2) to identify optimal communication strategies to promote vaccination and mitigation behaviors, and 3) to examine brain health outcomes of SARS-CoV-2 infection and examine their longevity.

Methods of the 2020 (Wave 1) International Tobacco Control (ITC) Korea Survey.

This article presents methods used in the 2020 International TC Korea Wave 1 (KRA1) Survey. To date, three cohorts of Korean respondents have participated in the larger ITC Korea Project (cohort 1: 2005-2014, cohort 2: 2016, and cohort 3: 2020-present). The overall objectives of the ITC KRA1 Survey were to examine the use of cigarettes, heated tobacco products (HTPs), e-cigarettes (ECs); whether HTPs might help smokers quit; and the effectiveness of tobacco control policies, such as large graphic warnings, high cigarette taxes, and smoking bans in public places.

Functional and structural modifications of influenza antibodies during pregnancy.

Pregnancy represents a unique tolerogenic immune state which may alter susceptibility to infection and vaccine response. Here, we characterized humoral immunity to seasonal influenza vaccine strains in pregnant and non-pregnant women. Although serological responses to influenza remained largely intact during late pregnancy, distinct modifications were observed.
