Impact of prepartum administration of a vaccine against infectious calf diarrhea on nonspecific colostral immunoglobulin concentrations of dairy cows.

Passive transfer of colostral immunoglobulins from the cow to the calf is essential for calf health. The objective of this study was to determine if prepartum administration of a vaccine stimulates increased concentrations of colostral immunoglobulins of dairy cows beyond what is explained by vaccine-specific immunoglobulins. A prospective cohort study was conducted on a spring-calving commercial dairy farm that had a policy of only vaccinating cows with even ear tag numbers with a calf diarrhea vaccine, whereas cows with odd ear tag numbers were left unvaccinated.

The length of the receiver operating characteristic curve and the two cutoff Youden index within a robust framework for discovery, evaluation, and cutoff estimation in biomarker studies involving improper receiver operating characteristic curves.

During the early stage of biomarker discovery, high throughput technologies allow for simultaneous input of thousands of biomarkers that attempt to discriminate between healthy and diseased subjects. In such cases, proper ranking of biomarkers is highly important. Common measures, such as the area under the receiver operating characteristic (ROC) curve (AUC), as well as affordable sensitivity and specificity levels, are often taken into consideration.

Marital Status Disruptions and Internalizing Disorders of Children.

Marital disruption (i.e., separation or divorce) impacts an estimated 40-50% of married couples.

Interracial couples and breastfeeding initiation in the United States.

In the past decade, the prevalence of interracial couples has steadily increased. Recent reports state that nearly one in five marriages are between spouses of different races. Interracial couples receive less social support and are more likely to separate.

Discordance in Couples Pregnancy Intentions and Breastfeeding Duration: Results from the National Survey of Family Growth 2011-2013.

Background: Parental disagreement in pregnancy intention elevates the risk of adverse health events for mother and child. However, research surrounding parental pregnancy intention discrepancies and breastfeeding duration is limited. This study aims to examine the relationship between couple's discordant pregnancy intention and breastfeeding duration.

The Role of Paternity Acknowledgment in Breastfeeding Noninitiation.

Background: In the United States, less than a quarter of mothers breastfeed in accordance with national recommendations. To date, researchers have demonstrated that paternal support directly influences breastfeeding outcomes; however, healthcare practitioners may not be able to quantify a lack of support in the immediate postpartum period. Research aim: The aim is to investigate the relationship between breastfeeding noninitiation and paternity acknowledgment, a factor that can be easily identified in the immediate postpartum period.

Associations of Partner Age Gap at Sexual Debut with Teenage Parenthood and Lifetime Number of Partners.

Context: Age at sexual debut and age gap between partners at debut are modifiable characteristics that may be related to risky sexual behaviors. Understanding any such relationships is a necessary first step toward strengthening risk interventions.

Methods: Age at sexual debut and partner age gap were examined for 3,154 female and 2,713 male respondents to the 2011-2013 National Survey of Family Growth who first had intercourse before age 18.

Treatment of afibrinogenemia in a chihuahua.

This report discusses the diagnosis and treatment of afibrinogenemia in a Chihuahua. Prolongations of prothrombin time (PT), activated partial thromboplastin time (aPTT), and thrombin clotting time (TCT) together with fibrinogen assay results of either no or trace amounts of fibrinogen support a diagnosis of afibrinogenemia. Differential diagnoses include common coagulopathies, liver failure, and disseminated intravascular coagulation (DIC).
