Results of a Health Education Message Intervention on HPV Knowledge and Receipt of Follow-up Care among Latinas Infected with High-Risk Human Papillomavirus

A clinic-based intervention study was conducted among high-risk human papillomavirus (HPV)-infected Latinas aged 18-64 years between April 2006 and May 2008 on the Texas-Mexico border. Women were randomly assigned to receive a printed material intervention (n=186) or usual care (n=187) and were followed at three months, six months, and 12 months through telephone surveys and review of medical records. The HPV knowledge of nearly all women had increased greatly, but only two-thirds of women reported they had received follow-up care within one year of diagnosis regardless of additional health education messaging. Our findings suggest that, regardless of type of health education messaging, Latinas living on the Texas-Mexico border are aware that follow-up care is recommended, but they may not receive this care. Individual, familial and medical care barriers to receipt of follow-up care may partially account for the higher rates of cervical cancer mortality in this region

HLA-B*35-Px–mediated acceleration of HIV-1 infection by increased inhibitory immunoregulatory impulses

A subset of HLA-B*35 alleles, B*35-Px, are strongly associated with accelerated HIV-1 disease progression for reasons that are not understood. Interestingly, the alternative set of B*35 subtypes, B*35-PY, have no detectable impact on HIV-1 disease outcomes, even though they can present identical HIV-1 epitopes as B*35-Px molecules. Thus, the differential impact of these alleles on HIV-1 disease progression may be unrelated to interactions with HIV-1–specific CD8+ T cells. Here, we show that the B*35-Px molecule B*3503 binds with greater affinity to immunoglobulin-like transcript 4 (ILT4), an inhibitory MHC class I receptor expressed on dendritic cells, than does the B*35-PY molecule B*3501, even though these two B*35 molecules differ by only one amino acid and present identical HIV-1 epitopes. The preferential recognition of B*3503 by ILT4 was associated with significantly stronger dendritic cell dysfunction in in vitro functional assays. Moreover, HIV-1–infected carriers of B*3503 had poor dendritic cell functional properties in ex vivo assessments when compared with carriers of the B*3501 allele. Differential interactions between HLA class I allele subtypes and immunoregulatory MHC class I receptors on dendritic cells thus provide a novel perspective for the understanding of MHC class I associations with HIV-1 disease progression and for the manipulation of host immunity against HIV-1

Abstinence-only-until-marriage : An Updated review of U.S. policies and programs and their impact

Adolescence is marked by the emergence of human sexuality, sexual identity and the initiation of intimate relations; within this context, abstinence from sexual intercourse can be a healthy choice. However, programs that promote abstinence-only-until-marriage (AOUM) or sexual risk avoidance (SRA), are scientifically and ethically problematic and—as such—have been widely rejected by medical and public health professionals. Although abstinence is theoretically effective, in actual practice, intentions to abstain from sexual activity often fail. Given a rising age at first marriage around the world, a rapidly declining percentage of young people remain abstinent until marriage. Promotion of AOUM policies by the United States (U.S.) government has undermined sexuality education in the U.S. and in U.S. foreign aid programs; funding for AOUM continues in the U.S. The weight of scientific evidence finds that AOUM programs are not effective in delaying initiation of sexual intercourse or changing other sexual risk behaviors. AOUM programs, as defined by U.S. federal funding requirements, inherently withhold information about human sexuality and may provide medically inaccurate and stigmatizing information. Thus, AOUM programs threaten fundamental human rights to health, information, and life. Young people need access to accurate and comprehensive sexual health information to protect their health and lives

Corporate Governance for Sustainability

The current model of corporate governance needs reform. There is mounting evidence that the practices of shareholder primacy drive company directors and executives to adopt the same short time horizon as financial markets. Pressure to meet the demands of the financial markets drives stock buybacks, excessive dividends and a failure to invest in productive capabilities. The result is a ‘tragedy of the horizon’, with corporations and their shareholders failing to consider environmental, social or even their own, long-term, economic sustainability. With less than a decade left to address the threat of climate change, and with consensus emerging that businesses need to be held accountable for their contribution, it is time to act and reform corporate governance in the EU. The statement puts forward specific recommendations to clarify the obligations of company boards and directors and make corporate governance practice significantly more sustainable and focused on the long term

Setting Priorities in Global Child Health Research Investments: Assessment of Principles and Practice

Članak daje pregled teoretskih i praktičnih pristupa postavljanju prioriteta prilikom ulaganja u istraživanje dječjega globalnog zdravlja. Daje i pregled prijašnjih pokušaja razvitka odgovarajućih alata i postupaka u području ulaganja u istraživanja o zdravlju. Napravljen je kratak pregled najvažnijih teoretskih postavki prema kojima bi se trebalo ravnati u postupku određivanja prioriteta. On je pokazao da će se različiti pristupi u postavljanju prioriteta, poput medicinskoga, gospodarskoga, zakonskoga, etičkoga, društvenoga, političkoga, pragmatičnoga, filozofskoga, onoga od poslodavaca i svih drugih nužno sukobiti. Posebno smo raspravili aktualne pravce istraživanja u području globalnoga dječjega zdravlja i njihov odnos prema Milenijskom cilju br. 4 organizacije Ujedinjenih naroda (UN), koji je da se između 1990. i 2015. dječja smrtnost smanji za dvije trećine. Procijenjena su postignuća pristupa koji su bili ranije primjenjivani i prikazane njihove prednosti i mane. Navedeni su razlozi organizacije Inicijativa za dječje zdravlje i prehranu (engl., Child Health and Nutrition Research Initiative) za stvaranje nove metodologije određivanja prioriteta u ulaganju u zdravstvena istraživanja i navedeni su razlozi za njezinu primjenu u području globalnoga dječjega zdravlja. Da bi se mogli obuhvatiti svi kutovi iz kojih je moguće promatrati prioritete ulaganja u istraživanja zdravlja nuždan je interdisciplinarni pristup. Određivanje prioriteta traži da njihovo stvaranje bude javno, jasno i sustavno i da u obzir uzme mnogobrojna gledišta i nastavi se na prednosti prethodnih pristupa.This article reviews theoretical and practical approaches to priority setting in global child health research investments. It also provides an overview of previous attempts to develop appropriate tools and methodologies to define priorities in health research investments. A brief review of the most important theoretical concepts that should govern priority setting processes is undertaken, showing how different perspectives, such as medical, economical, legal, ethical, social, political, rational, philosophical, stakeholder driven, and others will necessarily conflict each other in determining priorities. We specially address present research agenda in glo

Innate partnership of HLA-B and KIR3DL1 subtypes against HIV-1

Allotypes of the natural killer (NK) cell receptor KIR3DL1 vary in both NK cell expression patterns and inhibitory capacity upon binding to their ligands, HLA-B Bw4 molecules, present on target cells. Using a sample size of over 1,500 human immunodeficiency virus (HIV)+ individuals, we show that various distinct allelic combinations of the KIR3DL1 and HLA-B loci significantly and strongly influence both AIDS progression and plasma HIV RNA abundance in a consistent manner. These genetic data correlate very well with previously defined functional differences that distinguish KIR3DL1 allotypes. The various epistatic effects observed here for common, distinct KIR3DL1 and HLA-B Bw4 combinations are unprecedented with regard to any pair of genetic loci in human disease, and indicate that NK cells may have a critical role in the natural history of HIV infection
