Effects Of Supplemental Fish Oil On Resting Metabolic Rate, Body Composition, And Salivary Cortisol In Healthy Adults, Eric E. Noreen, Michael J. Sass, Megan L. Crowe, Vanessa A. Pabon, Josef Brandauer, Lindsay K. Averill

Health Sciences Faculty Publications

Background: To determine the effects of supplemental fish oil (FO) on resting metabolic rate (RMR), body composition, and cortisol production in healthy adults.

Methods: A total of 44 men and women (34 ± 13y, mean+SD) participated in the study. All testing was performed first thing in the morning following an overnight fast. Baseline measurements of RMR were measured using indirect calorimetry using a facemask, and body composition was measured using air displacement plethysmography. Saliva was collected via passive drool and analyzed for cortisol concentration using ELISA. Following baseline testing, subjects were randomly assigned in a double blind manner to one …

Concurrent Sexual Partnerships Do Not Explain The Hiv Epidemics In Africa: A Systematic Review Of The Evidence, Larry Sawers, Eileen Stillwaggon

Economics Faculty Publications

The notion that concurrent sexual partnerships are especially common in sub-Saharan Africa and explain the region’s high HIV prevalence is accepted by many as conventional wisdom. In this paper, we evaluate the quantitative and qualitative evidence offered by the principal proponents of the concurrency hypothesis and analyze the mathematical model they use to establish the plausibility of the hypothesis.

We find that research seeking to establish a statistical correlation between concurrency and HIV prevalence either finds no correlation or has important limitations. Furthermore, in order to simulate rapid spread of HIV, mathematical models require unrealistic assumptions about frequency of sexual …

Neighborhood And Individual Level Socioeconomic Variation In Perceptions Of Racial Discrimination, Amy B. Dailey, Stanislav V. Kasl, Theodore R. Holford, Tene T. Lewis, Beth A. Jones

Health Sciences Faculty Publications

In approaching the study of racial discrimination and health, the neighborhood and individual-level antecedents of perceived discrimination need further exploration. We investigated the relationship between neighborhood and individual-level socioeconomic position (SEP), neighborhood racial composition, and perceived racial discrimination in a cohort of African-American and White women age 40-79 from Connecticut, USA.

Design. The logistic regression analysis included 1249 women (39% African- American and 61% White). Neighborhood-level SEP and racial composition were determined using 1990 census tract information. Individual-level SEP indicators included income, education, and occupation. Perceived racial discrimination was measured as lifetime experience in seven situations.

Results. For African-American women, …

Orthostatic-Induced Hypotension Attenuates Cold Pressor Pain Perception, Karen Y. Wonders, Daniel G. Drury

Health Sciences Faculty Publications

In recent years, numerous studies have established a connection between blood pressure and nocioception. While this connection is well documented in the literature, its underlying physiological mechanisms have yet to be elucidated. Much attention has focused on the relationship between cardiovascular regulatory centers and nocioception, yet the intricacies of this relationship have not been fully explored. Therefore, the purpose of this investigation was to examine the role of the baroreflex system as a modulator of pain perception. Twenty normotensive males participated in two laboratory sessions. Time to cold pain threshold and pain tolerance was measured at rest during the first …

Exercise-Associated Hyponatremia During Winter Sports, Kristin J. Stuempfle

Health Sciences Faculty Publications

Exercise-associated hyponatremia (EAH) is hyponatremia that occurs greater than or equal to twenty four hours after prolonged physical activity. It is a potentially serious complication of marathons, triathlons, and ultradistance events, and can occur in hot and cold environments Clear evidence indicates that EAH is a dilutional hyponatremia caused by excessive fluid consumption and the inappropriate release of arginine vasopressin. Cerebral and pulmonary edema can cause serious signs and symptoms, including altered mental status, respiratory distress, seizures, coma, and death. Rapid diagnosis and urgent treatment with hypertonic saline is necessary to prevent severe complications or death. Prevention is based on …
