Health-related quality of life in long-term Caribbean prostate cancer survivors: comparisons with prostate cancer-free men.

Purpose: Prostate cancer (PCa) and its treatment can impact health-related quality of life (HRQoL). There are few studies of HRQoL in long-term PCa survivors of African ancestry from low- and middle-income countries. We examined the effect of PCa treatment on HRQoL of Jamaican PCa survivors compared with cancer-free controls and explored the effect of demographic and clinical factors on these outcomes.

Central adiposity at diagnosis may reduce prostate cancer-specific mortality in African-Caribbean men with prostate cancer: 10-year follow-up of participants in a case-control study.

Purpose: General and central adiposity are associated with the risk of developing prostate cancer (PCa), but the role of these exposures on PCa survival among men of African ancestry are less studied. This study aimed to investigate the association of anthropometry at diagnosis with all-cause and PCa-specific mortality and evaluate whether androgen deprivation therapy (ADT) modulated this risk.

Methods: Associations between body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) at diagnosis and mortality were examined in 242 men with newly diagnosed PCa enrolled between 2005 and 2007 and re-evaluated 10.

Understanding the health and production impacts of endemic Chlamydia pecorum infections in lambs.

Lamydia pecorum is a globally recognised livestock pathogen that is capable of causing severe and economically significant diseases such as arthritis in sheep and cattle. Relatively little information is available on the clinical progression of disease and the long-term effects of asymptomatic and symptomatic chlamydiosis in sheep. Recent studies in calves indicate that endemic C.

Molecular and serological dynamics of infection in a longitudinal study of prime lamb production.

Background: is a globally significant livestock pathogen causing pathology and production losses. The on-farm infection and serological dynamics and the relevance of existing diagnostic tools for diagnosing in livestock remains poorly characterized. In this study, we characterized the antigen and antibody dynamics of this pathogen in a longitudinal study of prime lamb production, utilizing the infection focused -specific 16S rRNA qPCR assay and serology based chlamydial Complement fixation Test (CFT).

Humoral immune response against two surface antigens of Chlamydia pecorum in vaccinated and naturally infected sheep.

Chlamydia pecorum is a globally recognised livestock pathogen due to the significant clinical and economic impact it poses to livestock producers. Routine serological diagnosis is through a complement fixation test (CFT), which is often criticised for cross-reactivity, poor sensitivity and specificity. Although serology remains the preferred method in veterinary diagnostic laboratories, serological assays based on surface antigens of C.

Relatively little published information is available on the clinical, diagnostic and pathologic features of C.

Chlamydia pecorum infections in sheep and cattle: A common and under-recognised infectious disease with significant impact on animal health.

There is a growing recognition that infections of livestock by the obligate intracellular bacterium, Chlamydia pecorum, are more widespread than was previously thought. A range of diseases have been associated with this pathogen, with the most important manifestations including infectious arthritis, infertility, enteritis, reduced growth rates, mastitis, and pneumonia. C.

Evaluation of the relationship between Chlamydia pecorum sequence types and disease using a species-specific multi-locus sequence typing scheme (MLST).

Chlamydia pecorum is globally associated with several ovine diseases including keratoconjunctivitis and polyarthritis. The exact relationship between the variety of C. pecorum strains reported and the diseases described in sheep remains unclear, challenging efforts to accurately diagnose and manage infected flocks.

Research participants' opinions on genetic research and reasons for participation: a Jackson Heart Study focus group analysis.

The Jackson Heart Study (JHS) convened focus groups to engage the community in dialogue on participation in the National, Heart, Lung and Blood Institute's Candidate Gene Resource (CARe) project. CARe, a genome wide association and candidate gene study, required the release of participant phenotypic and genotypic data with storage at NIH for widespread distribution to qualified researchers. The authors wanted to assess the willingness of an African American community to participate in the genetics research, given the past history of bioethical misconduct in ethnic minority communities.

Prevalence and trends in overweight and obesity among Mississippi public school students, 2005-2013.

This study estimated the prevalence of overweight and obesity in Mississippi public school students in grades K-12 and assessed changes in the prevalence between 2005 and 2013. In 2013, Body Mass Index was calculated using measured height and weight data for a weighted representative sample of 4,402 public school students. Additional analyses compared 2013 prevalence estimates by gender, race, and grade levels and for changes between 2005 and 2013.

Treatment of hypertension among African Americans: the Jackson Heart Study.

Hypertension treatment regimens used by African American adults in the Jackson Heart Study were evaluated at the first two clinical examinations (2415 treated hypertensive persons at examination I [exam I], 2000-2004; 2577 at examination II [exam II], 2005-2008). Blood pressure (BP) was below 140/90 mm Hg for 66% and 70% of treated participants at exam I and exam II, respectively. The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure treatment targets were met for 56% and 61% at exam I and exam II, respectively.

Developing a research agenda for cardiovascular disease prevention in high-risk rural communities.

The National Institutes of Health convened a workshop to engage researchers and practitioners in dialogue on research issues viewed as either unique or of particular relevance to rural areas, key content areas needed to inform policy and practice in rural settings, and ways rural contexts may influence study design, implementation, assessment of outcomes, and dissemination. Our purpose was to develop a research agenda to address the disproportionate burden of cardiovascular disease (CVD) and related risk factors among populations living in rural areas. Complementary presentations used theoretical and methodological principles to describe research and practice examples from rural settings.

Age is positively associated with high-density lipoprotein cholesterol among African Americans in cross-sectional analysis: the Jackson Heart Study.

Background: African Americans have historically had high high-density lipoprotein cholesterol (HDL-C) compared with other races and ethnicities.

Objective: We sought to characterize whether there is a cross-sectional association between age and HDL-C in a contemporary community-based study of African Americans.

Methods: Cross-sectional data were modeled by logistic regression for predictors of HDL-C among African Americans, ages 35-74, participating in the baseline examination of a community-based study of cardiovascular disease in Jackson, Mississippi, during 2000-2004.

Relationships of BMI to cardiovascular risk factors differ by ethnicity.

The burden of cardiovascular risk associated with obesity disproportionately affects African Americans and little is known about ethnic/racial differences in the relationship of obesity to cardiometabolic risk. This report assesses whether obesity is similarly associated with cardiometabolic risk factors in African Americans and whites of European ancestry. Cross-sectional observational data from the Jackson Heart Study (JHS) and the Framingham Heart Study (FHS) were compared.

Dyslipidemia and the treatment of lipid disorders in African Americans.

Background: Despite the high prevalence of cardiovascular disease documented among the African-American population, there has been little emphasis on the role of dyslipidemia as a prominent risk factor in this large subpopulation. Questions of medication efficacy also have been raised. Together, these factors may have affected awareness, diagnosis, and treatment rates.
