Hepatitis B virus seroconversion rates among health sciences students in the southeastern United States

ABSTRACT

Objective: To investigate the hepatitis B virus (HBV) seroconversion rate among health sciences students. Participants: The study included pharmacy, doctor of nursing, and medical students over 18 years of age enrolled at the University of South Carolina between 2007 and 2011. Methods: The primary end point was HBV seroconversion rates among students at the initial reporting period. Seroconversion was defined as hepatitis B surface antibody (anti-HBs) level greater than or equal to 10 mIU/mL. Multivariate regression analysis was used to determine predictive factors of seroconversion. Results: Of 777 records, data were available for 709 students. An 83.9% seroconversion rate was observed after a mean of 10 years between vaccine receipt and anti-HBs evaluation. Students with incomplete HBV vaccine series and longer time between initial series and evaluation were less likely to exhibit antibody response. Conclusions: These data highlight the importance of assessment and documentation of HBV vaccination series among health sciences students prior to direct patient care activities.     

Adversarial Allies: Care,Harm, and Resistance in the Helping Professions

Professional encounters bestow moral esteem upon professional helpers while denigrating those who access services. Yet society is arranged in such a way that professional services are indispensable for many to survive, and service users can experience them as simultaneously helpful and oppressive. We explore the ambivalent figure of the professional “adversarial ally” working within these systems through accounts from two research studies that straddle or resist the common-sense line that separates care from harm. Professionals need to acknowledge how we are experienced as adversaries in order to better forge relationships of solidarity or “alliance” with those using social and medical services.     

Birth Weight And The Linear Statistical Model

Linear modals are used to disentangle the effects of several factors on the birth weight distribution of human infants. Parameters of interest include the overall mean and standard deviation, mean weights of infants of ‘low’ and ‘high’ birth weight; and proportions of ‘low weight’ infants. Conclusions vary strongly with the parameter concerned and in some instances are quite surprising.     

Energy analysis: A review of methods and applications

The paper describes the aims and applications of energy analysis, emphasising its role as a complement to conventional financial analysis. It is shown to provide useful insights in applications such as forecasting price rises due to a fuel price rise, calculating the net costs of fuel obtained from unconventional sources, forecasting energy demand and evaluating energy conservation schemes. Although the field is still young, and most activity is in compiling reliable data bases, its systems approach and methods promise to make it a useful tool for evaluating patterns of resource uses.     

Meeting the Needs of the Adoption Triangle Through Open Adoption: The Birthmother

Open adoption is a relatively new and controversial practice. However, in many cultures this practice is traditional. In this first of a series of articles, the affect of open adoption upon birthparents is discussed. The open process facilitates appropriate grieving, enables decision making and furthers the growth of the birthmother.     

Themes on circulation in the third world

"This article focuses upon circulation, or reciprocal flows of people, with specific reference to Third World societies." Aspects considered include attempts to standardize terminology and to formulate typologies of population movement; the development of explanatory models of circulation and modernization, social networks, family welfare, and capitalism; and "the transfer of methods and concepts to societies and populations different from those from which they initially evolved and in which they were first tested."     

Retirement and Productive Activity in Later Life

It is commonly believed that as people age and leave the labor force, they disengage from productive activity and become dependent. While consistent with the conventional economic view of what constitutes productive activity, this belief is inconsistent with a more contemporary view that unpaid work (domestic, volunteer, and caring work) is equally economically valuable (i.e., productive). We investigate differences in how people allocate time among productive and other activities pre- and post-retirement. Results indicate that people remain engaged in productive activities even as they move out of the labor force, substituting unpaid for paid work. Only respondents who have exceeded their normal life expectancy greatly reduce their productive activity. Evidence suggests a need to revisit assumptions underlying policy debate on population aging.
