Mitotic activity: A systematic literature review of the assessment methodology and prognostic value in canine tumors.

One of the most relevant prognostic indices for tumors is cellular proliferation, which is most commonly measured by the mitotic activity in routine tumor sections. The goal of this systematic review was to analyze the methods and prognostic relevance of histologically measuring mitotic activity that have been reported for canine tumors in the literature. A total of 137 articles that correlated the mitotic activity in canine tumors with patient outcome were identified through a systematic (PubMed and Scopus) and nonsystematic (Google Scholar) literature search and eligibility screening process.

Mitotic activity: A systematic literature review of the assessment methodology and prognostic value in feline tumors.

Increased proliferation is a driver of tumorigenesis, and quantification of mitotic activity is a standard task for prognostication. This systematic review is an analysis of all available references on mitotic activity in feline tumors to provide an overview of the assessment methods and prognostic value. A systematic literature search in PubMed and Scopus and a nonsystematic search in Google Scholar were conducted.

Impact of air humidity on the tenacity of different agents in bioaerosols.

Despite the variety of pathogens that are transmitted via the airborne route, few data are available on factors that influence the tenacity of airborne pathogens. In order to better understand and thus control airborne infections, knowledge of these factors is important. In this study, three agents, S.

Atypical Mitotic Figures Are Prognostically Meaningful for Canine Cutaneous Mast Cell Tumors.

Cell division through mitosis (microscopically visible as mitotic figures, MFs) is a highly regulated process. However, neoplastic cells may exhibit errors in chromosome segregation (microscopically visible as atypical mitotic figures, AMFs) resulting in aberrant chromosome structures. AMFs have been shown to be of prognostic relevance for some neoplasms in humans but not in animals.

Objective: Innovative teaching strategies such as case-based learning and hands-on training are more and more integrated into undergraduate veterinary teaching. Nevertheless, it can be assumed that lectures still play an important role in many vet schools. Nowadays, however, lectures are questioned to be motivating and engaging enough for a long-lasting learning retention.

Paid family leave and parental investments in infant health: Evidence from California.

This paper evaluates the effect of Paid Family Leave (PFL) on breastfeeding and immunizations- two critical parental investments in infant health - which we identify using California's 2004 PFL policy that ensured mothers up to six weeks of leave at a 55% wage replacement rate. We employ difference-in-difference and difference-in-difference-in-differences models for a large, representative sample of children (N = 314,532) born between 2000 and 2013 drawn from the restricted-use versions of the 2003-2014 National Immunization Surveys. Our most conservative estimates indicate that access to PFL is associated with at least a 15% increase in breastfeeding exclusively for at least six months.
