The Advisory Committee on Immunization Practices recommends routine human papillomavirus (HPV) immunization for 11- to 12-year-old adolescents. In 2008, Louisiana required the school boards to distribute HPV vaccine information to parents or guardian of students in Grades 6 to 12. This article investigates the impact of this policy on HPV vaccination among 13- to 17-year-old female adolescents using National Immunization Survey-Teen (NIS-Teen) data. Drawing on the data from the 2008 to 2012 NIS-Teen, we compared the difference in proportions of females who have been vaccinated before and after the policy. Using difference-indifference estimation, we explored the change in vaccination rates before and after the policy implementation in Louisiana compared with Alabama and Mississippi, two states that did not have such a policy in place. The difference-in-differences estimates for HPV vaccination were not significant. Physician recommendation for HPV vaccination was significantly associated with vaccination among females in Louisiana and Alabama (adjusted odds ratio [aOR] = 7.74; 95% confidence interval [CI; 5.22, 11.5]), and for those in Louisiana and Mississippi (aOR = 7.05; 95% CI [4.6, 10.5]). Compared to the proportion of female adolescents who had received physician recommendation in Alabama or Mississippi, the proportion in Louisiana did not increase significantly in the postpolicy period. HPV vaccination rates did not increase significantly in Louisiana compared to Alabama or Mississippi following the implementation of the policy. Despite Louisiana's policy, physician recommendation remains the key determinant of HPV vaccination. HPV vaccine awareness does not necessarily result in HPV vaccination.

Objectives More than 10 % of pregnant women in the United States (U.S.) suffer from depression, which has far-reaching consequences on maternal and fetal well-being. There is conflicting evidence regarding the prevalence of antenatal depression among different race and ethnic groups. This systematic review aimed to summarize the existing literature concerning racial/ethnic disparities in the prevalence and correlates of antenatal depression in the U.S. Methods PubMed, CINAHL and PsycINFO databases were searched online for research studies published in English in peer-reviewed journals until March 2015, using a pre-designed search strategy. Eligibility was determined using pre-specified criteria; and quality was assessed. Results Forty-one (41) articles met the criteria; 13 were cross-sectional, and 21 were longitudinal studies. Overall, the prevalence of antenatal depression was 10-30 %; it was higher among non-Hispanic blacks (NHBs) and Hispanics, compared to non-Hispanic whites (NHWs). Few studies looked at the correlates of depression by race/ethnicity. Among employed women, higher depression scores were observed among NHBs, compared to NHWs; while there was no racial difference among unemployed women. Racial difference and race-employment interaction disappeared once discrimination was accounted for. In another study, higher parity, higher stress, and lower self-esteem were significant correlates of depression among NHBs, while less satisfaction with social support, and higher stress predicted higher depression scores among NHWs and Hispanics respectively. Conclusions The findings of our review suggest that not only is antenatal depression a major public health issue that needs to be addressed, but different racial/ethnic groups seem to differ in their vulnerability and risk factors., Author(s): Soumyadeep Mukherjee[sup.1] , Mary Jo Trepka[sup.1] , Dudith Pierre-Victor[sup.1] , Raed Bahelah[sup.1] , Tenesha Avent[sup.1] Author Affiliations: (1) Department of Epidemiology, Robert Stempel College of Public Health and Social [...]

Objective: Parents play an integral role in young adults' sexual health including human papillomavirus (HPV) vaccine decision-making. The objective of this study was to explore conversations regarding sexual activity in Haitian households and the influence of such conversations on young Haitian women's HPV vaccine discussion with their parents. Methods: From a large university in the southeastern United States, 30 Haitian-American college women (ages 17–26) were recruited for semi-structured in-depth interviews. The interviews were recorded and transcribed verbatim. Interview transcripts were analyzed using thematic analysis. Results: Most participants stated that they either did not have conversations regarding sexual activity or the conversations that they had were described as 'uncomfortable' or 'awkward'. Many participants stated that once parents knew that HPV is sexually transmitted, their discussions about the vaccine would be considered an announcement of their sexual debut or sexual activity. Hence, many decided to not discuss the HPV vaccine with their parents. Conclusion: Findings have important implications for HPV vaccine uptake. Results showed that a lack of conversations about sexual activity within Haitian households led to limited discussions about the HPV vaccine among young Haitian-American college women and their parents. Future HPV vaccine uptake efforts should integrate familial and cultural beliefs about female sexuality, while focusing on cervical cancer prevention. [ABSTRACT FROM AUTHOR]

Human papillomavirus (HPV) infection is the most common sexually transmitted infection worldwide and has been linked to several cancers, including cervical cancer. In the United States, the Southern region has a disproportionate burden of cervical cancer, and research about the epidemiology of HPV in the region is scarce. This study estimates the prevalence and correlates of HPV infection among 14-59 year-old females. Data from 4,250 females aged 14-59 years collected during the 2007'2010 National Health and Nutrition Examination Survey (NHANES) were used. We estimated the prevalence of HPV infection for the South and the rest of the country. We performed weighted chi-square test and logistic regression to examine the association between HPV infection and various demographics. Among 14'26 year-old females, the prevalence of high-risk oncogenic HPV types was 25.6% (95% confidence (CI): 22.4-33.3) in the South and 29.1% (95% CI: 24.8-33.8) in the rest of the country (p= 0.15). Among 27-59 year-old women, infection from high-risk oncogenic types was 20.9% (95% CI: 17.4-24.9) in the South compared to 14.5% (95% CI: 12.9-16.3) in the rest of the country (p=0.0001). This study found a higher prevalence of infection from high-risk oncogenic types among 27-59 year-old females in the South compared to the rest of the country, but not among the 14-26 year-olds. These findings highlight the importance of promoting HPV vaccination as well as cervical cancer screening, particularly in the Southern region. [ABSTRACT FROM AUTHOR]

Precision medicine is a revolutionary approach to disease prevention and treatment that takes into account individual differences in lifestyle, environment, and biology. The US National Institutes of Health has recently launched The All of Us Research Program (2016) to extend precision medicine to all diseases by building a national research cohort of one million or more US participants. This review is limited to how the human microbiome factors into precision medicine from the applied aspect of preventing and managing cancer. The Precision Medicine Initiative was established in an effort to address particular characteristics of each person with the aim to increase the effectiveness of medical interventions in terms of prevention and treatment of multiple diseases including cancer. Many factors contribute to the response to an intervention. The microbiome and microbially produced metabolites are capable of epigenetic modulation of gene activity, and can influence the response through these mechanisms. The fact that diet has an impact on microbiome implies that it will also affect the epigenetic mechanisms involving microbiota. In this chapter, we review some major epigenetic mechanisms, notably DNA methylation, chromatin remodeling and histone modification, and noncoding RNA, implicated in cancer prevention and treatment. Several examples of how microbially produced metabolites from food influence cancer risk and treatment response through epigenetic mechanisms will be discussed. Some challenges include the limited understanding of how diet shapes the microbiome and how to best evaluate those changes since both, diet and the microbiota, exhibit daily and seasonal variations. Ongoing research seeks to understand the relationship between the human microbiome and multiple diseases including cancer.
