Clinical decision-making to address poor outcomes in persistent horizontal semicircular canal benign paroxysmal positional vertigo: A case study.

Background: Horizontal semicircular canal BPPV (HSC-BPPV) can occur in 10-30% of BPPV cases. Lower success rates are reported for HSC-BPPV. The apogeotropic form of HSC-BPPV is more difficult to treat, as 5-40% of cases are described to be refractory to repositioning maneuvers.

Rodent-Pika Parasite Spillover in Western North America.

Competition during the Cenozoic expansion of the Rodentia may have contributed to ecological niche reduction of pikas, which are now increasingly under threat as their habitat degrades under global climate change, while some rodents expand their ranges and overlap with pikas. Range overlap carries the possibility of disease spillover. Contemporary North American pikas are cold-adapted and relegated primarily to alpine environments where they subsist on relatively low-quality herbaceous diet.

Diversity of Flea (Siphonaptera) Parasites on Red Foxes (Vulpes vulpes) in Romania.

Red foxes (Vulpes vulpes (L.)) are widespread across Europe, tolerant of synanthropic ecosystems, and susceptible to diseases potentially shared with humans and other animals. We describe flea fauna on red foxes in Romania, a large, ecologically diverse country, in part because fleas may serve as an indicator of the risk of spillover of vector-borne disease.

Outcomes Following a Vestibular Rehabilitation and Aerobic Training Program to Address Persistent Post-Concussion Symptoms.

Purpose: To describe changes in adults with persistent symptoms and disability following a concussion after completing a supervised home exercise vestibular rehabilitation (VR) program combined with aerobic training.

Method: Participants included 14 consecutive individuals referred for VR within the context of a comprehensive concussion center. Outcome measures were administered at initial evaluation, 3 mos, and 6 mos.

The Impact of Menstrual Cycle Phase on Economic Choice and Rationality.

It is well known that hormones affect both brain and behavior, but less is known about the extent to which hormones affect economic decision-making. Numerous studies demonstrate gender differences in attitudes to risk and loss in financial decision-making, often finding that women are more loss and risk averse than men. It is unclear what drives these effects and whether cyclically varying hormonal differences between men and women contribute to differences in economic preferences.

Region-Specific Summation Patterns Inform the Role of Cortical Areas in Selecting Motor Plans.

Given an instruction regarding which effector to move and what location to move to, simply adding the effector and spatial signals together will not lead to movement selection. For this, a nonlinearity is required. Thresholds, for example, can be used to select a particular response and reject others.

A preliminary study to evaluate postural improvement in subjects with scoliosis: active therapeutic movement version 2 device and home exercises using the Mulligan's mobilization-with-movement concept.

Objective: The purpose of this preliminary study was to determine if the use of Active Therapeutic Movement Version 2 (ATM2) device and home exercises using the Mulligan's mobilization-with-movement concept by subjects with scoliosis would result in postural improvement and to document any changes in trunk range of motion and quality of life.

Methods: Forty-three subjects between the ages of 12 to 75 years were recruited for the study. Each subject underwent a low back evaluation along with specific measurements for their scoliosis.

Exercising control: exercise intention and perceived constraints in older adults with osteoarthritis.

Purpose Of The Study: Maintaining perceived psychological control in older adulthood is beneficial for health, well-being, and adjustment to chronic illness. Theoretically, control over specific, personally meaningful domains should inform general control beliefs. Thus, the objective of the present study was to examine perceived control over the exercise domain (operationalized as exercise intention belief) for its ability to predict general control beliefs in a sample of older adults with chronic illness over 1 year.

Health-Related Social Control over Physical Activity: Interactions with Age and Sex.

Despite the disease prevention benefits of engaging in life-long regular physical activity, many adults remain sedentary. The social environment provides an important context for health and health behavior across the lifespan, as well as a potential point of intervention for increasing physical activity. Self-reports of perceived social support, social strain, positive social control, and negative social control were examined for their cross-sectional relationships to physical activity frequency in purposive samples of younger and older adults (N = 371, ages from 18 to 97, 68% women).

Nurses' attitudes toward continuing formal education: a comparison by level of education and geography.

The education of nurses has an influence on patient safety and outcomes, the nursing shortage, the faculty shortage, and nurses' attitudes and actions. This article reports on a dissertation study designed to examine the attitudes of nurses, initially registered with an associate degree or diploma in nursing, toward continuing formal education. Actively licensed registered nurses in the eastern and western United States (n=535) participated.

Registered nurses returning to school for a bachelors degree in nursing: Issues emerging from a meta-analysis of the research.

This literature review was conducted to determine what is known about nurses' attitudes and perceptions about returning to school. There are four societal influences making nursing continuing education important: (1) Many nurses are still practicing with an Associate's degree or diploma and few continue their formal education; (2) Recent studies have indicated that there are improved patient outcomes in hospitals which employ higher educated nurses; (3) A poor economy during a nursing shortage means high demand and less incentive for nurses to return to school for higher education; and (4) The worsening faculty shortage means an increased need for nurses to advance their education. Understanding nurses' attitudes and perceptions may help identify gaps in our knowledge, determine ways to foster positive attitudes toward education learning among nurses, and allow us to entice nurses to return to school.

Cultural influences for college student language brokers.

Children from immigrant families often translate communication for parents, a process known as language brokering (LB). LB begins in childhood, but may continue through emerging adulthood, even when individuals are in college. We surveyed 1,222 university students with two immigrant parents and compared non-language brokers, infrequent language brokers, and frequent language brokers on a variety of ethnic, cultural, and identity measures.

No strain, no gain: psychosocial predictors of physical activity across the adult lifespan.

Background: Physical activity is an essential ingredient in the recipe for successful aging, yet physical activity engagement declines with advancing age.

Methods: In a national sample of 3848 participants aged 32 to 84 (55% women), we examined potential psychosocial moderators of the relationship between age and physical activity.

Results: In a cross-sectional hierarchical multiple regression analysis [Adj.

Psychosocial and behavioural contributors to health: age-related increases in physical disability are reduced by physical fitness.

The aging process is associated with increased risk for disease which can cause physical and economic burden for older adults. In a national longitudinal sample of 3910 participants aged 24-75 years (55% women), we examined psychosocial and behavioural factors associated with physical health in adulthood. With hierarchical regression analyses controlling for Time 1 values of the dependent variable and demographic characteristics, we found that participants reporting better social relations, a higher sense of control, a smaller waist circumference and greater physical activity at Time 1 reported better self-rated physical health (Adj.

Acculturation and gender: influence on healthy dietary outcomes for Latino adolescents in California.

Objective: Examine acculturation and gender on intention to eat a healthful diet among Latino adolescents using the Theory of Planned Behavior.

Design: Secondary analysis of data set and condensed version of the Short Acculturation Scale for Hispanics (SASH).

Setting: Data collected from 34 randomly selected high schools in San Bernardino, CA.

Attitude: a concept analysis.

This paper presents a concept analysis conducted as a beginning step to developing research on nurses' attitudes toward advancing formal education. A literature review, conducted by the author, confirmed that the term attitude is used prolifically in nursing research; however, the findings were inconclusive as to a definition and the attributes of an "attitude." Often this concept was either not defined or vaguely defined.

An evaluation of the seminal work of Patricia Benner: theory or philosophy?

The purpose of this article is to review the seminal work of Patricia Benner, From Novice to Expert, in order to assert it as a philosophy and not a theory. In the literature there is no clear consensus on where this model stands - theory or philosophy. There is no intent to devalue Patricia Benner's work as it is valuable and has become widely used in nursing practice, research, education and administration.
