Utilization of genetic testing prior to subspecialist referral for cerebellar ataxia.

Objective: To evaluate the utilization of laboratory testing in the diagnosis of cerebellar ataxia, including the completeness of initial standard testing for acquired causes, the early use of genetic testing, and associated clinical and nonclinical factors, among a cohort referred for subspecialty consultation.

Methods: Data were abstracted from records of 95 consecutive ataxia patients referred to one neurogenetics subspecialist from 2006-2010 and linked to publicly available data on characteristics of referral clinicians. Multivariable logistic and linear regression models were used to analyze unique associations of clinical and nonclinical factors with laboratory investigation of acquired causes and with early genetic testing prior to referral.

Sexual risk behaviors and acceptability of HIV pre-exposure prophylaxis among HIV-negative gay and bisexual men in serodiscordant relationships: a mixed methods study.

The objective of this mixed methods study was to examine current sexual risk behaviors, acceptability and potential adoption of pre-exposure prophylaxis (PrEP) for HIV prevention, and sexual behavior intentions with PrEP adoption among HIV-negative gay and bisexual men (GBM) in HIV serodiscordant relationships. A multiracial/ethnic sample of 25 HIV-negative GBM in serodiscordant relationships completed a qualitative interview and a brief interviewer-administered survey. A modified grounded theory approach was used to identify key themes relating to acceptability and future adoption of PrEP.

A qualitative study about self-medication in the community among market vendors in Fuzhou, China.

Despite government efforts to increase healthcare insurance and access in China, many individuals, regardless of insurance status, continue to engage in high levels of self-medication. To understand the factors influencing common self-medication behaviour in a community of food market vendors in Fuzhou China, a total of 30 market vendors were randomly recruited from six food markets in 2007. In-depth interviews were conducted with each participant at their market stalls by trained interviewers using a semi-structured open-ended interview protocol.

Motivators, concerns, and barriers to adoption of preexposure prophylaxis for HIV prevention among gay and bisexual men in HIV-serodiscordant male relationships.

The purpose of this study was to identify factors that may facilitate or impede future adoption of preexposure prophylaxis (PrEP) for HIV prevention among gay and bisexual men in HIV-serodiscordant relationships. This qualitative study utilized semistructured interviews conducted with a multiracial/-ethnic sample of 25 gay and bisexual HIV-serodiscordant male couples (n=50 individuals) recruited from community settings in Los Angeles, CA. A modified grounded theory approach was employed to identify major themes relating to future adoption of PrEP for HIV prevention.

Entertainment Venue Visiting and Commercial Sex in China.

Entertainment venues in China play an important role in the sexually transmitted disease (STD)/HIV epidemic. Most previous studies have focused on sex workers working in entertainment venues, but little is known about their clients. This study investigated the perceptions and behavior of the patrons visiting entertainment venues.

Sociocultural contexts and communication about sex in China: informing HIV/STD prevention programs.

HIV may be particularly stigmatizing in Asia because of its association with "taboo" topics, including sex, drugs, homosexuality, and death (Aoki, Ngin, Mo, & Ja, 1989). These cultural schemata expose salient boundaries and moral implications for sexual communication (Chin, 1999, Social Science and Medicine, 49, 241-251). Yet HIV/STD prevention efforts are frequently conducted in the public realm.

Impacts of HIV/AIDS Stigma on Family Identity and Interactions in China.

This study examines the impact of HIV-related stigma on families living with HIV/AIDS in China. In-depth, semistructured interviews were conducted with 30 people living with HIV/AIDS and with 15 of their family members, including spouses, parents, and siblings. Findings show that HIV-related stigma is associated with bringing shame to the family, losing family "face," and damaging within-family relations and broader family social networks.

Why patients go online: multiple sclerosis, the internet, and physician-patient communication.

Background: The online information seeking of multiple sclerosis (MS) patients, their reasons for doing so, and its importance for physician-patient communication have not been described.

Methods: Patients (n = 61) presenting for the first time at an MS clinic from December 2003 to July 2005 were interviewed pre- and postappointment and administered standard measures of pain and health quality of life. Consultations were audio recorded.

Intergenerational and urban-rural health habits in Chinese families.

Objective: To explore intergenerational health habits and compare differences between urban and rural families.

Methods: A total of 2500 families with children ages 6-18 in China were surveyed regarding their health habits.

Results: Urban families reported significantly greater food variety and more time exercising (for fathers and children) than did rural families.

Dealing with epilepsy: parents speak up.

In this study, focus groups were used to examine parents' attitudes toward mental health services, use of mental health and other services, as well as service-related and other challenges encountered by parents of children with epilepsy. Both quantitative and qualitative analytic approaches were used to analyze the transcripts of 36 parents grouped into six focus groups by socioeconomic status (SES) (high, low) and ethnicity (African-American, Caucasian, Hispanic). The quantitative analyses demonstrated that, irrespective of SES and ethnicity, the parents were highly aware of their children's behavioral, emotional, and cognitive difficulties and the lack of knowledge about epilepsy among medical, educational, and mental health professionals.

Prepared patients: internet information seeking by new rheumatology patients.

Objective: To investigate to what extent and why new rheumatology patients access medical information online prior to first appointments and secondarily to ask whether they discuss information gained from the Internet with physicians.

Methods: Research was conducted in a teaching rheumatology clinic with a nonrandom sample of 120 English-speaking adults presenting for first appointments in rheumatology. Quantitative and qualitative data were gained in pre- and postappointment patient surveys and interviews, including online information gathering prior to first appointment, demographics, health status, information usage in patient-physician interactions, and satisfaction.

HIV/STD stigmatization fears as health-seeking barriers in China.

Internationally, stigma prohibits effective HIV/STD identification, prevention, and care. Interviews with 106 persons in an urban center in Eastern China, some known to have engaged in stigmatized risk acts (sex workers, STD clinic patients) and some vulnerable for stigmatization fears to influence health-seeking behaviors (market employees, rural-to-urban migrants). Interviews focused on community norms, values, beliefs, and emotional and behavioral reactions to HIV/STD stigmatization related events.

Impact of interpreters' approach on Latinas' use of amniocentesis.

Communication difficulties in multicultural clinical settings can be exacerbated by translators, but their actual impact on medical decisions has not been systematically evaluated. This study sought to determine the influence of translators participating in clinical encounters in which English-speaking clinicians offered amniocentesis to Spanish-speaking women by conducting systematic observations of 61 prenatal genetic consultations and recording translators' training and background characteristics and patients' amniocentesis decisions. Translators' behavioral styles were classified according to 10 inductively determined criteria.
