The purpose of this study was to identify dimensions of elder mistreatment in Chinese and Korean immigrant communities and to increase sociocultural understanding of such mistreatment by elucidating the complexities of abuse embedded in unique social and cultural contexts. In-depth interviews were conducted with 20 local professionals working primarily in Asian elderly advocacy, and six focus group discussions were conducted involving 60 community members in the San Francisco Bay area. Five dimensions of elder mistreatment were identified: psychological abuse, neglect by a trusted person, financial exploitation, physical abuse, and sexual abuse. In general, fewer Korean community member participants reported having observed physical or financial abuse than Chinese groups, but they reported greater knowledge of situations involving psychological abuse, neglect by a trusted person, and sexual abuse. The contexts of cultural influences and immigration and acculturation were salient themes that shaped participants' subjective perceptions and beliefs about elder abuse and hence help-seeking behaviors.

BACKGROUND

Use of mobile health (mHealth) tools has expanded rapidly but little research has been done on its acceptability by low-income, diverse, older patient populations.

OBJECTIVE

To assess the attitudes of a diverse group of underserved women on the acceptability and usability of mHealth tools in a clinical setting using a breast health questionnaire application (app) at a public hospital mammography clinic.

METHODS

Semi-structured interviews were conducted in a breast-imaging center of an urban safety net institution from July-August 2012. Interviews included pre- and post-questions. Women completed the Athena breast health questionnaire app on an iPad and were asked about their experience and ways to improve the tool.

RESULTS

Fifteen women age 45-79 years from diverse ethnic and educational backgrounds were interviewed. The majority of women, 11 of 15, preferred the Athena app over a paper version and all the women thought the app was easy to use. Two Spanish-speaking Latinas preferred paper; and two women, with limited mobile phone use, did not have a preference. Many women indicated that it would be necessary to have staff available for instruction and assistance if the app were to be implemented.

CONCLUSIONS

mHealth tools are an acceptable, if not preferred, method of collecting health information for diverse, older, low-income women. Further studies are required to evaluate the reliability and accuracy of data collection using mHealth tools in underserved populations. mHealth tools should be explored as a novel way to engage diverse populations to improve clinical care and bridge gaps in health disparities.

The incidence of esophageal cancer has been increasing while the prognosis remains very poor. Endoscopic submucosal dissection (ESD) was developed in Japan for en bloc resection of early gastric cancer with excellent results. The use of ESD in early squamous cell cancer (SCC) of the esophagus in Japan has been increasing with long-term results comparable to those in early gastric cancer. The use of ESD in Barrett's neoplasia in western countries has been challenged by the low complete resection rates and the risk of metachronous lesions from surrounding non-dysplastic Barrett's epithelium. Efforts to combine ESD with other treatment modalities such as radiofrequency ablation in Barrett's neoplasia and chemoradiation in SCC appear to be promising. The use of steroid therapy (local or systemic) has been demonstrated to prevent post-ESD stenosis, which is the most common complication after esophageal ESD.

BACKGROUND

Effective strategies to identify and screen children at risk for HIV are needed. The objectives of this study were to evaluate the utilization of a family information table (FIT) to identify and test at-risk children in Kenya and identify factors associated with child testing.

METHODS

A cross-sectional study was conducted among HIV-infected adults with children at five Kenyan clinics. HIV testing status for children aged ≤18 years was gathered from the patients' FITs and compared to reports from in-person clinic visits as the gold standard. Generalized estimating equations were used to assess predictors for HIV testing of children adjusted for confounders and within parent correlation.

RESULTS

Our sample included 384 HIV-infected adults enrolled in care with 933 reported children. Overall, 323 FITs (84%) correctly listed all children in the family and 340 (89%) documented an HIV testing status (including untested) for all children. Seventy-five percent of parents verbally reported all children tested, compared to only 46% of FITs (OR=13.5, 95% CI 6.5-27.8). Verbal reports identified 739 (79%) children tested, with 55 (7.4%) HIV-positive and 17 (2.3%) HIV-exposed infants (HEI). Of 63 adults with HIV-positive children or HEI, 60 (95%) reported enrolling children into care. Likelihood that children had been tested was higher for younger children (≤4y vs. > 4y, aOR=2.0; 95% CI 1.4-2.9) and lower if the partner's serostatus was unknown vs. seropositive (aOR=0.3; 95% CI: 0.1-0.8).

CONCLUSIONS

Although the FIT may be a useful tool to identify children at risk for HIV, this study found underutilization by providers. To maximize impact of this tool, documentation of follow-up for untested and positive children is essential.

GLOBAL HEALTH IMPLICATIONS

Through early documentation of at-risk children and follow up of untested and infected children, the FIT may serve as an effective resource for improving HIV testing and linkage to care.

Adolescents and young adults are at high risk of human immunodeficiency virus (HIV) infection in sub-Saharan Africa. Previous reports have found that university students in Africa comprise a sexually active population, although the prevalence of HIV or sexually transmitted infections (STI) has not been measured. We conducted a cross-sectional survey of students from five large universities in Kampala, Uganda, using respondent-driven sampling. We asked students to complete behavioral questionnaires and provide biological samples to test for HIV, Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, Trichomonas vaginalis, and bacterial vaginosis. We enrolled 649 students and obtained interpretable data from 640. Around 50% of the respondents were male, and the mean age was 22 years. An estimated 0.8% (95% CI 0.0-2.0) of male students had Chlamydia infection, approximately 4.3% (95% CI 2.0-7.0) had syphilis, 0.4% (95% CI 0.0-0.9) had HIV, and none had gonorrhea. An estimated 32.6% (95% CI 22.4-40.8) of women had bacterial vaginosis, 2.5% (95% CI 0.7-6.3) had Chlamydia infection, 1.7% (95% CI 0.5-3.6) had syphilis, 1.0% (95% CI 0.0-2.4) had gonorrhea, 0.9% (95% CI 0.0-4.2) had trichomoniasis, and 0.9% (95% CI 0.0-1.8) had HIV. We found no significant risk factors for HIV or other STI among males. We also found that not using a condom during the latest sexual intercourse was significantly associated with HIV infection, other STI, or bacterial vaginosis (OR 2.16; 95% 1.26-3.78) among females. We conclude that while university students are sexually active and there is substantial risk for syphilis, there is little evidence of substantially increased HIV risk among them.

OBJECTIVE

To examine differences in tobacco-related attitudes and hookah and cigarette use among college and noncollege young adults.

PARTICIPANTS

Time-location samples of young adult bar patrons in San Diego, California (N = 2,243), Tulsa (N = 2,095) and Oklahoma City (N = 2,200), Oklahoma, Albuquerque (N = 1,044) and Las Cruces (N = 894), New Mexico, between September 2009 and July 2011.

METHODS

Multinomial logistic regression examined associations between hookah and cigarette use and tobacco-related attitudes.

RESULTS

Current college students and graduates are less likely to smoke cigarettes, but more likely to use hookah. Among current hookah users, 22.6% were hookah-only users and 77.4% were dual users (cigarettes and hookah). College status is associated with different hookah use patterns, and those with anti-tobacco industry attitudes were more likely to smoke hookah.

CONCLUSIONS

Novel interventions are needed for college students using hookah. Existing strategies targeting smokers with anti-tobacco industry messages may be irrelevant to hookah users.
