Hemipelvectomy is more routinely performed in canine and feline patients, but with the right candidate and owner commitment to aftercare, it may be safely and successfully performed in rabbits.
To the authors' knowledge, this was the first report of a hemipelvectomy performed in a rabbit. Hemipelvectomy is more routinely performed in canine and feline patients, but with the right candidate and owner commitment to aftercare, it may be safely and successfully performed in rabbits.Widespread use of antimicrobials in human and veterinary medicine drives the emergence and dissemination of resistant bacteria in human, animal, and environmental reservoirs. The AVMA and FDA Center for Veterinary Medicine have both taken public positions emphasizing the importance of incorporating antimicrobial stewardship in veterinary clinical settings; however, a model for implementing a comprehensive antimicrobial stewardship program in veterinary practice is not readily available. In 2015, The Ohio State University College of Veterinary Medicine began developing a veterinary antimicrobial stewardship program modeled on existing programs in human health-care institutions and the 7 core elements of a successful hospital antimicrobial stewardship program, as defined by the CDC. The program includes comprehensive antimicrobial use guidelines, active environmental surveillance, and enhanced infection control procedures in The Ohio State University Veterinary Medical Center, along with routine monitoring and reporting of antimicrobial prescribing practices and antimicrobial susceptibility patterns of common pathogens isolated from patients and the hospital environment. Finally, programs have been developed to educate clinicians, staff, and students on antimicrobial resistance and appropriate antimicrobial prescribing practices. The antimicrobial stewardship program has been designed to help clinicians and students confidently make judicious antimicrobial use decisions and provide them with actionable steps that can help them act as strong stewards while providing the best care for their patients. This report describes our program and the process involved in developing it, with the intent that the program could serve as a potential model for other veterinary medical institutions.
The aim of this study was to evaluate the use of a convolutional neural network (CNN) system for predicting C-shaped canals in mandibular second molars on panoramic radiographs.
Panoramic and cone beam CT (CBCT) images obtained from June 2018 to May 2020 were screened and 1020 patients were selected. Our dataset of 2040 sound mandibular second molars comprised 887 C-shaped canals and 1153 non-C-shaped canals. To confirm the presence of a C-shaped canal, CBCT images were analyzed by a radiologist and set as the gold standard. A CNN-based deep-learning model for predicting C-shaped canals was built using Xception. The training and test sets were set to 80 to 20%, respectively. Diagnostic performance was evaluated using accuracy, sensitivity, specificity, and precision. Receiver-operating characteristics (ROC) curves were drawn, and the area under the curve (AUC) values were calculated. Further, gradient-weighted class activation maps (Grad-CAM) were generated to localize the anatomy that contributed to the predictions.
The accuracy, sensitivity, specificity, and precision of the CNN model were 95.1, 92.7, 97.0, and 95.9%, respectively. Grad-CAM analysis showed that the CNN model mainly identified root canal shapes converging into the apex to predict the C-shaped canals, while the root furcation was predominantly used for predicting the non-C-shaped canals.
The deep-learning system had significant accuracy in predicting C-shaped canals of mandibular second molars on panoramic radiographs.

Feasibility assessments (FAs) are important to establish site capabilities to conduct clinical trials and their suitability for specific trials. However, current FA methods used by biotechnology and pharmaceutical (biotech-pharma) trial sponsors and contract research organizations (CROs) are costly, inefficient, unnecessarily burdensome, and resource intensive. These methods delay trial start-up, act as a barrier to site participation, and ultimately reduce timely patient access to clinical trials and novel treatments.
An ASCO Task Force was convened to assess the specific burdens and challenges with FAs and to develop recommendations to improve their efficiencies and effectiveness. Stakeholders (including trial sites, biotech-pharma sponsors, and CROs) provided insights into challenges and offered solutions through two surveys and an in-person meeting. The Task Force used the feedback to formulate consensus recommendations to improve FAs for oncology clinical trials.
Three key recommendations were idenburdens and ensure that more trial sites and patients have timely access to oncology clinical trials. To have meaningful impact, adoption and consistent execution of these recommendations across all trials, sponsors, CROs, and sites are essential.Endocrine-disrupting chemicals (EDCs) are xenobiotics that disrupt the endocrine system in humans at ecologically significant concentrations. Various substances are exposed to human health via routes including food, water, air and skin that result in disastrous maladies at low doses as well. Therefore EDCs need a meticulous strategy of analysis for dependable and consistent monitoring in humans. Tefinostat purchase The management and risk assessment necessitate advancements in the detection methodologies of EDCs. Hyphenated MS-based chromatograph and other validated laboratory analysis methods are widely available and employed. Besides, in vitro bioassay techniques and biosensors are also used to conduct accurate toxicological tests. This article provides a revision of various bioanalytical detection methods and technologies for the clinical estimation of EDCs.Purpose The aim of the study was to provide an updated systematic review of randomized controlled trials that studied the effectiveness of pharmacological and nonpharmacological interventions to prevent aspiration pneumonia in older adults at risk for aspiration. Method The search was conducted in MEDLINE (PubMed), Scopus, and Web of Science databases and the Cochrane Central Register of Controlled Trials, using a protocol registered on PROSPERO (CRD42019139973). Randomized controlled trials of interventions to reduce the incidence of aspiration pneumonia in individuals older than 65 years at risk for aspiration, published between January 2002 and July 2019 and written in English, were included. Two reviewers independently evaluated the methodological quality of studies using the revised Cochrane risk-of-bias tool. Results Thirteen out of 703 articles identified met the eligibility criteria and were included. Six studies focused on pharmacological interventions, three studies focused on dietary interventions and compensatory strategies, one study focused on oral care, two studies focused on multidisciplinary interventions, and one study assessed a screening method.
