Thrombin as a Potential Proxy to Select for Horn Fly Abundance in Beef Cattle.

Horn flies are a major nuisance to cattle and induce significant economic losses. Fly abundance varies within and across breeds and genetic analyses have shown sufficient genetic variation to permit selection. A major bottleneck for selecting against horn fly abundance is the complexity of measuring fly attraction phenotypes.

Resampling-based inferences for compositional regression with application to beef cattle microbiomes.

Gut microbiomes are increasingly found to be associated with many health-related characteristics of humans as well as animals. Regression with compositional microbiomes covariates is commonly used to identify important bacterial taxa that are related to various phenotype responses. Often the dimension of microbiome taxa easily exceeds the number of available samples, which creates a serious challenge in the estimation and inference of the model.

The impact of childhood maltreatment on women's reproductive health, with a focus on symptoms of polycystic ovary syndrome.

Background: Childhood maltreatment leads to lifelong health risks, particularly in women. Although reproductive health has been linked to such maltreatment, limited literature exists on its association with polycystic ovary syndrome (PCOS).

Objectives: In a sample of psychiatrically healthy women, we evaluated the impact of child maltreatment (subtypes of abuse and neglect) on women's reproductive health outcomes, specifically PCOS.

Nurses Have Names.

This postscript to the issue is a series of reflections by Dorothy Pringle, the previous editor-in-chief, on the contributions Lynn Nagle has made as editor-in-chief of the Canadian Journal of Nursing Leadership over the past 11 years and the richness of the perspectives of the authors of the 18 invited papers. The author also reflects on the contrast between the amount of attention and accolades nurses as care providers have received during the pandemic while having few, if any, nurses emerge as spokespeople or interpreters of the nursing roles and the contributions that nurses have made. Unlike other disciplines and despite their contributions, we have not learned the names of any nursing experts.

Drug Recovery and Copay Assistance Program in a Community Cancer Center: Charity and Challenges.

Purpose: The cost of cancer care is escalating dramatically, in part because of the rising expense of systemic cancer therapy. This creates financial dilemmas for patients and insurers and potential economic disruption for institutions attempting to provide cancer care to the underserved. Our institution initiated a drug recovery and copay assistance program (DRCAP) to mitigate the impact of the rising cost of parenteral medications.
