RESUMEN
Mississippi has some of the most pronounced racial disparities in HIV infection in the country; African Americans comprised 37% of the Mississippi population but represented 80% of new HIV cases in 2015. Improving outcomes along the HIV care continuum, including linking and retaining more individuals and enhancing adherence to medication, may reduce the disparities faced by African Americans in Mississippi. Little is understood about clergy's views about the HIV care continuum. We assessed knowledge of African American pastors and ministers in Jackson, Mississippi about HIV and the HIV care continuum. We also assessed their willingness to promote HIV screening and biomedical prevention technologies as well as efforts to enhance linkage and retention in care with their congregations. Four focus groups were conducted with 19 African American clergy. Clergy noted pervasive stigma associated with HIV and believed they had a moral imperative to promote HIV awareness and testing; they provided recommendations on how to normalize conversations related to HIV testing and treatment. Overall, clergy were willing to promote and help assist with linking and retaining HIV positive individuals in care but knew little about how HIV treatment can enhance prevention or new biomedical technologies such as pre-exposure prophylaxis (PrEP). Clergy underscored the importance of building coalitions to promote a collective local response to the epidemic. The results of this study highlight important public health opportunities to engage African American clergy in the HIV care continuum in order to reduce racial disparities in HIV infection.

BACKGROUND: Incarceration history is associated with lower rates of condom use and increased HIV risk. Less is known about duration of incarceration and multiple incarcerations' impact on condom use post-release. METHODS: In the current study, we surveyed 1,416 adults in Mississippi about their incarceration history and sexual risk behaviors. Generalized estimating equations (GEE) were used to test associations between duration of incarceration, multiple incarcerations, socio-demographic factors, substance use, sexual behavior, and event level condom use at last sex. RESULTS: After adjusting for covariates, having been incarcerated for at least 6 months two or more times remained significantly associated with condomless sex. CONCLUSIONS: This study found a strong, independent relationship between condom use and multiple, long-term incarceration events among patients in an urban STI clinic in the Deep South. The results suggest that duration of incarceration and multiple incarcerations have significant effects on sexual risk behaviors, underscoring the deleterious impact of long prison or jail sentences on population health. Our findings also suggest that correctional health care professionals and post-release providers might consider offering comprehensive sexual and reproductive health services and those providing community care should consider screening for previous incarceration as a marker of risk.

UNLABELLED: Dietary supplementation with vitamin K(1), with vitamin D(3) and calcium or their combination, was examined in healthy older women during a 2-year, double-blind, placebo-controlled trial. Combined vitamin K with vitamin D plus calcium was associated with a modest but significant increase in BMC at the ultradistal radius but not at other sites in the hip or radius. INTRODUCTION: The putative beneficial role of high dietary vitamin K(1) (phylloquinone) on BMD and the possibility of interactive benefits with vitamin D were studied in a 2-year double-blind, placebo-controlled trial in healthy Scottish women > or =60 years of age. MATERIALS AND METHODS: Healthy, nonosteoporotic women (n = 244) were randomized to receive either (1) placebo, (2) 200 microg/day vitamin K(1), (3) 10 microg (400 IU) vitamin D(3) plus 1000 mg calcium/day, or (4) combined vitamins K(1) and D(3) plus calcium. Baseline and 6-month measurements included DXA bone mineral scans of the hip and wrist, markers of bone turnover, and vitamin status. Supplementation effects were tested using multivariate general linear modeling, with full adjustment for baseline and potential confounding variables. RESULTS: Significant bone mineral loss was seen only at the mid-distal radius but with no significant difference between groups. However, women who took combined vitamin K and vitamin D plus calcium showed a significant and sustained increase in both BMD and BMC at the site of the ultradistal radius. Serum status indicators responded significantly to respective supplementation with vitamins K and D. Over 2 years, serum vitamin K(1) increased by 157% (p < 0.001), the percentage of undercarboxylated osteocalcin (%GluOC) decreased by 51% (p < 0.001), serum 25-hydroxyvitamin D [25(OH)D] increased by 17% (p < 0.001), and PTH decreased by 11% (p = 0.049). CONCLUSIONS: These results provide evidence of a modest synergy in healthy older women from nutritionally relevant intakes of vitamin K(1) together with supplements of calcium plus moderate vitamin D(3) to enhance BMC at the ultradistal radius, a site consisting of principally trabecular bone. The substantial increase in gamma-carboxylation of osteocalcin by vitamin K may have long-term benefits and is potentially achievable by increased dietary intakes of vitamin K rather than by supplementation.

INTRODUCTION: Acceptability and willingness to both take and pay for HIV self-tests (HIVSTs) in US neighbourhoods with high rates of HIV infection are not well understood. METHODS: We surveyed 1,535 individuals about acceptability and willingness to take and pay for an HIVST in a predominately African American neighbourhood with 3% HIV seroprevalence. We recruited individuals presenting for HIV screening services in a community-based programme. Latent class analysis (LCA) grouped individuals with similar patterns of HIV-risk behaviours and determined which groups would be most willing to use and buy HIVSTs. RESULTS: Nearly 90% of respondents were willing to use an HIVST; 55% were willing to buy HIVSTs, but only 23% were willing to pay the market price of US $40. Four distinct groups emerged and were characterized by risk behaviours: (1) low risk (N = 324); (2) concurrent partnerships (N = 346); (3) incarceration and substance use (N = 293); and (4) condomless sex/multiple partners (N = 538). Individuals in the low-risk class were less willing to self-test compared to concurrent sexual partners (OR = 0.39, p = .003) and incarceration and substance use (OR = 0.46, p = .011) classes. There were no significant differences across classes in the amount individuals were willing to pay for an HIVST. CONCLUSION: HIVSTs were overwhelmingly acceptable but cost prohibitive; most participants were unwilling to pay the market rate of US $40. Subsidizing and implementing HIVST programmes in communities with high rates of infection present a public health opportunity, particularly among individuals reporting condomless sex with multiple partners, concurrent sexual partnerships and those with incarceration and substance use histories.

OBJECTIVE: CDC has recommended routine HIV screening since 2006. However, few community health centers (CHCs) routinely offer HIV screening. Research is needed to understand how to implement routine HIV screening programs, particularly in medically underserved neighborhoods with high rates of HIV infection. A routine HIV screening program was implemented and evaluated in a Philadelphia, Pennsylvania, neighborhood with high rates of HIV infection. METHODS: Implementation science is the study of methods to promote the integration of research findings and evidence into health-care policy and practice. Using an implementation science approach, the results of the program were evaluated by measuring acceptability, adoption, and penetration of routine HIV screening. RESULTS: A total of 5,878 individuals were screened during the program. HIV screening was highly accepted among clinic patients. In an initial needs assessment of 516 patients, 362 (70.2%) patients reported that they would accept testing if offered. Routine screening policies were adopted clinic-wide. Staff trainings, new electronic medical records that prompted staff members to offer screening and evaluate screening rates, and other continuing quality-improvement policies helped promote screenings. HIV screening offer rates improved from an estimated 5.0% of eligible patients at baseline in March 2012 to an estimated 59.3% of eligible patients in December 2014. However, only 5,878 of 13,827 (42.5%) patients who were offered screening accepted it, culminating in a 25.2% overall screening rate. Seventeen of the 5,878 patients tested positive, for a seropositivity rate of 0.3%. CONCLUSION: Routine HIV screening at CHCs in neighborhoods with high rates of HIV infection is feasible. Routine screening is an important tool to improve HIV care continuum outcomes and to address racial and geographic disparities in HIV infection.

Frequent use of websites and mobile telephone applications (apps) by men who have sex with men (MSM) to meet sexual partners, commonly referred to as "hookup" sites, make them ideal platforms for HIV prevention messaging. This Rhode Island case study demonstrated widespread use of hookup sites among MSM recently diagnosed with HIV. We present the advertising prices and corporate social responsibility (CSR) programs of the top five sites used by newly diagnosed HIV-positive MSM to meet sexual partners: Grindr, Adam4Adam, Manhunt, Scruff, and Craigslist. Craigslist offered universal free advertising. Scruff offered free online advertising to selected nonprofit organizations. Grindr and Manhunt offered reduced, but widely varying, pricing for nonprofit advertisers. More than half (60%, 26/43) of newly diagnosed MSM reported meeting sexual partners online in the 12 months prior to their diagnosis. Opportunities for public health agencies to promote HIV-related health messaging on these sites were limited. Partnering with hookup sites to reach high-risk MSM for HIV prevention and treatment messaging is an important public health opportunity for reducing disease transmission risks in Rhode Island and across the United States.

Lymphoproliferative disease (LPD) is a recognized complication of primary immunodeficiency (PID) and immunodysregulatory syndromes. Historically, it has a very poor outcome. For patients surviving LPD, myeloablative hematopoietic stem cell transplantation (SCT) was the only cure for the underlying PID, with a high risk of developing posttransplantation complications, including recurrent lymphoproliferative disease. We describe 8 patients with a range of PID and immunodysregulatory syndromes complicated by LPD. After initial treatment of the LPD (including the use of anti-CD20 monoclonal antibody, rituximab, in 6 of the patients), all patients underwent reduced-intensity conditioning (RIC) SCT with prospective monitoring for Epstein-Barr virus (EBV) viremia. After transplantation, 3 patients received rituximab, and 3 patients received prophylactic EBV-specific cytotoxic T-lymphocytes. Only 1 patient developed recurrent LPD posttransplantation, which responded to rituximab. All patients who underwent transplantation survive free of LPD and are cured of their PID at a median follow-up of 4 years (range, 1-7 years). With careful monitoring and pre-emptive therapy, we advocate this RIC SCT approach to patients with PID who have pre-existing EBV-LPD.

OBJECTIVE: The aim of this study was to assess vitamin K status in an unselected population of children with cystic fibrosis (CF) and to investigate any vitamin K effect on bone turnover and bone mineral status. METHODS: Children > or =5 years of age who were attending the CF unit were invited to enter the study. Fasting blood samples were analyzed for levels of vitamin K1 and prothrombin produced in vitamin K absence; total, undercarboxylated, and carboxylated osteocalcin (OC); and bone-specific alkaline phosphatase and procollagen I carboxy-terminal propeptide (bone formation markers). Levels of N-telopeptide and free pyridinoline and deoxypyridinoline (bone breakdown products) were measured in urine samples. Bone mineral density and bone mineral content were measured at the lumbar spine and for the total body with a GE Lunar Prodigy densitometer. Statistical analyses were performed with Minitab version 9.1. RESULTS: One hundred six children entered the study. Sixty-five of 93 children (70%) from whom blood samples were obtained showed suboptimal vitamin K status, on the basis of low serum vitamin K1 levels, increased prothrombin produced in vitamin K absence levels, or both abnormalities. Vitamin K1 levels showed a significant negative correlation with undercarboxylated OC levels but showed no significant correlation with any marker of bone turnover or measurement of bone mineral status. Undercarboxylated OC levels were correlated significantly with bone turnover markers, which themselves showed a significant negative correlation with measurements of bone mineral density and content. There were no significant correlations between carboxylated or undercarboxylated OC levels and bone density measurements. CONCLUSIONS: Vitamin K1 deficiency is common among children with CF, and routine supplements should be considered. Through its role in the carboxylation of OC, vitamin K deficiency may be associated with an uncoupling of the balance between bone resorption and bone formation. A cause-effect relationship between vitamin K deficiency and low bone mass has not been proved.

Little is known of how the fat components of diets influence the absorption and metabolism of vitamin K and the possible consequences to the synthesis of vitamin K-dependent (VKD) proteins in different target organs. We have evaluated the effects of two diets on circulating phylloquinone (K1) and triacylglycerols (TAG). One diet was enriched with corn oil (CO) (also rich in gamma-tocopherol) and the other with an olive/sunflower (O/SO) mixture (rich in alpha-tocopherol). Effects on gamma-carboxylation were assessed from coagulation assays and sensitive assays for undercarboxylated prothrombin (ucFII) and osteocalcin (ucOC). Total plasma matrix Gla-protein (MGP) was also measured. After an initial adjustment diet, 26 healthy young men were fed, in a crossover design, the O/SO or CO diet for 2 weeks. Mean intakes of K1 during consumption of adjustment, O/SO, and CO diets were 225 microg/day, 291 microg/day, and 291 microg/day, respectively. Mean fasting levels of TAG and K1 were both significantly reduced by the CO diet, but not by the O/SO diet. Neither diet reduced FII activity but ucFII became detectable in nine subjects, eight of whom showed this abnormality with both diets. The CO diet induced a rise in ucOC (P < 0.05), which was negatively correlated to ucFII (r = -0.71, P < 0.03). The CO but not O/SO diet induced a decrease of total circulating MGP. We conclude that both oils, notably CO, affected vitamin K absorption and/or metabolism which may increase the requirements for gamma-carboxylation. The mechanism is unclear but may result from interactions of vitamin K with PUFA and/or other lipid components such as vitamin E.
