Despite these disparities, African American men are underrepresented in clinical trials and in studies on PCa biology and biomarker discovery. We used immunoseroproteomics to profile antitumor autoantibody responses in AA and European American (EA) men with PCa, and explored differences in these responses. This minimally invasive approach detects autoantibodies to tumor-associated antigens that could serve as clinical biomarkers and immunotherapeutic agents. Sera from AA and EA men with PCa were probed by immunoblotting against PC3 cell proteins, with AA sera showing stronger immunoreactivity. Mass spectrometry analysis of immunoreactive protein spots revealed that several AA sera contained autoantibodies to a number of proteins associated with both the glycolysis and plasminogen pathways, particularly to alpha-enolase (ENO1). The...

There are also indirect causal pathways including social and cultural factors which are particularly salient in India's traditional society. The purpose of this study was to explore women's perceptions of stillbirth and to determine how issues of gender and power, social support, coping efforts, and religious beliefs influence perinatal grief outcomes among poor women in rural Chhattisgarh, India. Structured interviews were done face-to-face in 21 randomly selected villages among women of reproductive age (N=355) who had experienced stillbirth (n=178) and compared to those who had not (n=177), in the Christian Hospital, Mungeli catchment area. Perinatal grief was significantly higher among women with a history of stillbirth. Greater perinatal grief was associated with lack of support, maternal agreement with social norms, and younger maternal age. These predictors must be understood in light of an additional finding-distorted sex ratios, which reflect gender discrimination in the context of Indian society. The findings of this study will allow the development of a culturally appropriate health education program which should be designed to increase social support and address social norms, thereby reducing psychological distress to prevent complicated perinatal grief. Perinatal grief is a significant social burden which impacts the health women.

Multivariate ordinal logistic regression showed that maternal infant-feeding method intention (measured prior to birth), sociodemographic characteristics, intrapartum variables, and early skin-to-skin mother-infant contact during the first 3 hours following birth (controlling for delivery hospital) were correlated with exclusive breastfeeding during the maternity hospitalization. Compared with mothers with no early skin-to-skin contact, exclusive breastfeeding was higher in mothers who experienced skin-to-skin contact for 1 to 15 minutes (odds ratio [OR] 1.376; 95% confidence interval [CI], 1.189-1.593), 16 to 30 minutes (OR 1.665; 95% CI, 1.468-1.888), 31 to 59 minutes (OR 2.357; 95% CI, 2.061-2.695), and more than 1 hour (OR 3.145; 95% CI, 2.905-3.405). The results demonstrate a dose-response relationship between early skin-to-skin contact and breastfeeding exclusivity.

A sample of 432 youth (between 13 and 23 years old) who were homeless or at imminent risk for homelessness were sampled from both service and street sites. The percentage of youth who reported exposure to each type of violence was calculated. Multiple regression analyses were used to examine differences in the risk of exposure to violence across gender, ethnicity, age, and length of time homeless. Respondents reported a high rate of exposure to violence. Female respondents reported levels of exposure to violence that were as high as those reported by males. Females were more likely to report having been sexually assaulted and fearing victimization, and tended to be less likely to report perpetrating violence. With a few exceptions, ethnic identity was not a significant predictor of exposure to violence or fear of victimization. Age tended to be inversely associated with risk of exposure to violence. Length of time homeless was not associated with fear of victimization. Homeless youth are at high risk for exposure to a variety of forms violence as both witnesses and victims. The overall rates of exposure to violence and patterns of association with demographic variables are significantly higher than those reported in national samples of adolescents.

This study measured symptoms of depression, low self-esteem, ADHD, suicidality, self-injurious behavior (SIB), and drug and alcohol use disorder in a sample of homeless youth and young adults living in Hollywood, CA. Results indicated extremely high prevalences of mental health problems, as compared with corresponding rates of mental health problems found among housed youths in previous studies. Prevalence of mental health problems differed by age and ethnicity. African Americans were at lower risk of suicidal thoughts and SIB than were those of other ethnicities. Older respondents and females were at increased risk of depressive symptoms, and younger respondents were at increased risk of SIB. Previous history of sexual abuse and/or assault was associated with increased risk of suicidality and SIB. Risk factors for drug abuse disorder included ethnicity other than African American, homelessness for 1 year or more, suicidality, SIB, depressive symptoms, and low self-esteem. Risk factors for alcohol abuse disorder included male gender, white ethnicity, homelessness for 1 year or more, suicidality, and SIB. Extremely high rates of mental health problems and substance abuse disorders in this sample suggest the need for street-based and nontraditional mental health services targeted toward these youths and young adults.

In the United States, lack of participation in screening for prostate cancer by black men is influenced by several cultural factors, including knowledge, health beliefs, barriers, and relationships with primary healthcare providers. We used the qualitative and paralleling descriptive quantitative findings of a mixed-method longitudinal study exploring prostate cancer screening behaviors among 277 black men. Five themes were identified as critical elements affecting men's screening for prostate cancer: lack of knowledge, communication, social support, quality of care, and sexuality. These themes were associated with a sense of disconnectedness by black men from the healthcare system and contributed to nonparticipation in prostate cancer early detection activities.

This study examined the prevalence of alcohol and other drug use reported by 1121 youth, ages 12-24 years, seen for an initial medical visit at a free community-based primary health clinic. The clinic, located in the Hollywood/Wilshire area of Los Angeles, serves both homeless (62%) and non-homeless (38%) youth. Bivariate and multivariate analyses revealed that the homeless youth were significantly more likely to report use of alcohol and illicit drugs (marijuana, stimulants, hallucinogens, and narcotics) and prior involvement in injecting drug use (IDU). Variables found to be significantly associated with substance use among the homeless youth included length of time homeless, an attempted suicide, physical and sexual abuse, and involvement in survival sex/prostitution. Among the non-homeless youth, age of first intercourse, a previous suicide attempt, and a history of physical and sexual abuse were significantly associated with substance use. These findings suggest that rates of alcohol and other drug use may be higher among youth seen at community-based primary health clinics, particularly homeless youth underscoring the need for screening for these risk variables.

In response, the ENRRICH Project was implemented by Loma Linda University researchers and their local community partner CCAEJ to investigate the potential linkage between proximity to the railyard and adverse health outcomes. The project used a community-based participatory research approach with mixed methods. Qualitative inquiry was conducted to contextually inform the quantitative study, in which randomly selected residents (N=715) near the railyard and further away (controls) were interviewed by rigorously trained residents. Data was coded for recurrent themes and organized into overarching categories. Themes and trends were then concurrently analyzed with qualitative and quantitative methods, involving GIS, word clouds, and statistics to allow characterization of...
