Improving Cervical Cancer Screening and HPV Vaccination Rates among Ghanaians in Ghana, and Ghanaian Immigrants Living in Georgia, U.S.A

Introduction: Cervical cancer is the most common type of HPV- associated cancer, disproportionately affecting minority women worldwide. Various strains of the human papillomavirus have been linked to the incidence of this disease. The gradual development of cervical cancer makes it one of the most preventable female cancers, as malignant cell changes can take up to two decades to occur. Regular Pap smears lead to early detection of persistent HPV infection. Together with HPV vaccination, Pap smears are effective in controlling cervical cancer incidence. Although these preventative programs are readily available in the U.S., screening, and vaccination rates have been consistently suboptimal among immigrants. Previous studies have examined the enablers as well as the challenges experienced by immigrants in accessing cervical cancer prevention services. The purpose of this qualitative research was to explore the attitudes, barriers, and sociocultural factors that facilitate the uptake of cervical cancer preventative services among Ghanaians in Ghana, and Ghanaian immigrants living in Georgia. Methods: Semi-structured interviews were conducted in two parts; (a) a preliminary study in Ghana with 35 females and 15 males, and (b) the main study in Georgia, U.S.A. among Ghanaian immigrants, with 17 females and 10 males. Nvivo 12 was used to code the interview transcriptions, from which emerging themes and sub-themes were identified. The Social Ecological Model and the Theory of Reasoned Action were applied to examine the impact of personal and contextual influences on the participants’ decision to access prevention programs. Results: Barriers to screening and vaccination included the lack of knowledge, fear of cervical cancer, fear of the side effects of the HPV vaccine, embarrassment with a physical examination, and cost. Facilitators to screening and vaccination included increased knowledge of and access to cervical cancer prevention programs, health insurance, and encouragement from healthcare providers to utilize these services. Immigration, improved knowledge, and access to Pap smear and HPV vaccines were the strongest influences of change. Conclusion: The study results show that health education and social support could significantly improve the willingness of Ghanaian immigrants to access Pap smear and HPV vaccination. These findings could serve as an outline for the implementation of related programs in Georgia, and other locations with similar high-risk populations

Ethical Approaches to Mandating Influenza Vaccinations for Local Health Department Workforce in Georgia

Background: The seasonal influenza illness occurs every year in the United States during the cooler months from October to April, sometimes lasting longer. Although certain populations are more susceptible to this condition, data have shown that otherwise healthy individuals have experienced alarming rates of morbidity and mortality associated with these infections. Despite the CDC’s recommendation for influenza vaccination for all HCWs, compliance have been lagging among local health departments’ workforce. This practice arguably exposes a wide cross section of the U.S. population to the flu, while being served in these facilities. The utilitarian approach provides a framework to examine the ethical implications to the public of mandating influenza vaccination for these employees. Methods: A systematic review of peer-reviewed literature was conducted to address the following research questions: 1) Do local public health departments in Georgia mandate annual influenza vaccinations?  2) What are the ethical considerations for mandating influenza vaccinations for public health employees? and 3) What are the ethical considerations for mandating influenza vaccinations for the community? Twenty-five articles were included in the review. Results: Descriptive analysis shows that there is no mandatory vaccination policy in place for state or local departments in health in the state of Georgia. Most of the literature available relates to policy implementation within acute or long-term care facilities. A systematic review of mandatory influenza vaccination for public health workers focused on four areas: theoretical approaches to increase influenza vaccination coverage and support of, opposition to, and alternative strategies for influenza vaccinations. Conclusions: The utilitarian approach is sufficient for the influenza vaccination policy- making strategies and in the ethical approaches of mandating influenza vaccinations for local health department workforce in Georgia if need be, for vaccination targets are to be achieved

The prevalence of pain and disability one year post fracture of the distal radius in a UK population: A cross sectional survey

<p>Abstract</p> <p>Background</p> <p>A fracture of the distal radius is a commonly occurring fracture and accounts for a third of all fractures in the elderly. Thus far, one year estimates of pain and disability following a fracture of the distal radius have been reported on Canadian populations. The primary aim of this study is to investigate the prevalence of pain and disability in a UK population one year post fracture of the distal radius.</p> <p>Methods</p> <p>A cross-sectional survey was undertaken, of all subjects suffering a fracture of the distal radius between October 2005 and February 2006 in Nottingham, UK. Primary outcomes used were the VAS for pain and the DASH for disability. Prevalence of pain and disability were calculated and odds ratios presented for associations between demographics, pain and disability.</p> <p>Results</p> <p>93/264 (35%) subjects responded to the questionnaire. 6 subjects did not fulfill the inclusion criteria and were excluded from further analysis. 11% of subjects reported moderate to very severe pain. 16% of subjects reported moderate to very severe disability. Statistically significant associations were found between pain medication usage for the wrist fracture and moderate to very severe pain (OR 11.20, 95% CI 2.05 – 61.23). Moderate to very severe disability was associated with older age (OR 6.53, 95%CI 1.65 – 25.90) and pain medication usage for the wrist fracture (OR 4.75, 95% CI 1.38 – 16.37). Working was associated with a reduction in risk of moderate to very severe disability (OR 0.14, 95% CI 0.03 – 0.67).</p> <p>Conclusion</p> <p>This study demonstrates that there are a small proportion of patients who are still suffering moderate to very severe pain and disability one year post fracture of the distal radius. The study also demonstrates that there are significant associations between characteristics of the patients and the level of pain and disability. This highlights the need for further research into the most appropriate management of these patients in order to reduce this burden of pain and disability, particularly as this is a predominantly elderly patient group.</p

ART Suppresses Plasma HIV-1 RNA to a Stable Set Point Predicted by Pretherapy Viremia

Current antiretroviral therapy is effective in suppressing but not eliminating HIV-1 infection. Understanding the source of viral persistence is essential for developing strategies to eradicate HIV-1 infection. We therefore investigated the level of plasma HIV-1 RNA in patients with viremia suppressed to less than 50–75 copies/ml on standard protease inhibitor- or non-nucleoside reverse transcriptase inhibitor-containing antiretroviral therapy using a new, real-time PCR-based assay for HIV-1 RNA with a limit of detection of one copy of HIV-1 RNA. Single copy assay results revealed that >80% of patients on initial antiretroviral therapy for 60 wk had persistent viremia of one copy/ml or more with an overall median of 3.1 copies/ml. The level of viremia correlated with pretherapy plasma HIV-1 RNA but not with the specific treatment regimen. Longitudinal studies revealed no significant decline in the level of viremia between 60 and 110 wk of suppressive antiretroviral therapy. These data suggest that the persistent viremia on current antiretroviral therapy is derived, at least in part, from long-lived cells that are infected prior to initiation of therapy

Lack of Detectable HIV-1 Molecular Evolution during Suppressive Antiretroviral Therapy

A better understanding of changes in HIV-1 population genetics with combination antiretroviral therapy (cART) is critical for designing eradication strategies. We therefore analyzed HIV-1 genetic variation and divergence in patients' plasma before cART, during suppression on cART, and after viral rebound. Single-genome sequences of plasma HIV-1 RNA were obtained from HIV-1 infected patients prior to cART (N = 14), during suppression on cART (N = 14) and/or after viral rebound following interruption of cART (N = 5). Intra-patient population diversity was measured by average pairwise difference (APD). Population structure was assessed by phylogenetic analyses and a test for panmixia. Measurements of intra-population diversity revealed no significant loss of overall genetic variation in patients treated for up to 15 years with cART. A test for panmixia, however, showed significant changes in population structure in 2/10 patients after short-term cART (<1 year) and in 7/10 patients after long-term cART (1-15 years). The changes consisted of diverse sets of viral variants prior to cART shifting to populations containing one or more genetically uniform subpopulations during cART. Despite these significant changes in population structure, rebound virus after long-term cART had little divergence from pretherapy virus, implicating long-lived cells infected before cART as the source for rebound virus. The appearance of genetically uniform virus populations and the lack of divergence after prolonged cART and cART interruption provide strong evidence that HIV-1 persists in long-lived cells infected before cART was initiated, that some of these infected cells may be capable of proliferation, and that on-going cycles of viral replication are not evident

Genetic risk and a primary role for cell-mediated immune mechanisms in multiple sclerosis.

Multiple sclerosis is a common disease of the central nervous system in which the interplay between inflammatory and neurodegenerative processes typically results in intermittent neurological disturbance followed by progressive accumulation of disability. Epidemiological studies have shown that genetic factors are primarily responsible for the substantially increased frequency of the disease seen in the relatives of affected individuals, and systematic attempts to identify linkage in multiplex families have confirmed that variation within the major histocompatibility complex (MHC) exerts the greatest individual effect on risk. Modestly powered genome-wide association studies (GWAS) have enabled more than 20 additional risk loci to be identified and have shown that multiple variants exerting modest individual effects have a key role in disease susceptibility. Most of the genetic architecture underlying susceptibility to the disease remains to be defined and is anticipated to require the analysis of sample sizes that are beyond the numbers currently available to individual research groups. In a collaborative GWAS involving 9,772 cases of European descent collected by 23 research groups working in 15 different countries, we have replicated almost all of the previously suggested associations and identified at least a further 29 novel susceptibility loci. Within the MHC we have refined the identity of the HLA-DRB1 risk alleles and confirmed that variation in the HLA-A gene underlies the independent protective effect attributable to the class I region. Immunologically relevant genes are significantly overrepresented among those mapping close to the identified loci and particularly implicate T-helper-cell differentiation in the pathogenesis of multiple sclerosis

A telephone survey of parental attitudes and behaviours regarding teenage drinking

<p>Abstract</p> <p>Background</p> <p>Irish teenagers demonstrate high rates of drunkenness and there has been a progressive fall in age of first drinking in recent decades. International research indicates that parents exert substantial influence over their teenager's drinking. We sought to determine the attitudes and behaviours of Irish parents towards drinking by their adolescent children.</p> <p>Methods</p> <p>We conducted a telephone survey of a representative sample of of 234 parents who had a teenager aged between 13 and 17 years.</p> <p>Results</p> <p>Six per cent reported that they would be unconcerned if their son or daughter was to binge drink once per month. On the issue of introducing children to alcohol in the home, 27% viewed this as a good idea while 63% disagreed with this practice. Eleven per cent of parents reported that they had given a drink to their teenager at home. Parents who drank regularly themselves, who were from higher socio-demographic groups and who lived in the east of Ireland demonstrated more permissive attitudes to teenage drinking.</p> <p>Conclusions</p> <p>We found no evidence of widespread permissive attitudes and behaviours among Irish parents. Given that parental influences have been demonstrated to exert substantial impact on teenage drinking, it may be possible to harness the concerns of Irish parents more effectively to reverse the trends of escalating alcohol related harm in Ireland.</p

PRNP variation in UK sporadic and variant Creutzfeldt Jakob disease highlights genetic risk factors and a novel non-synonymous polymorphism

<p>Abstract</p> <p>Background</p> <p>Genetic analysis of the human prion protein gene (<it>PRNP</it>) in suspect cases of Creutzfeldt-Jakob disease (CJD) is necessary for accurate diagnosis and case classification. Previous publications on the genetic variation at the <it>PRNP </it>locus have highlighted the presence of numerous polymorphisms, in addition to the well recognised one at codon 129, with significant variability between geographically distinct populations. It is therefore of interest to consider their influence on susceptibility or the clinico-pathological disease phenotype. This study aimed to characterise the frequency and effect of <it>PRNP </it>open reading frame polymorphisms other than codon 129 in both disease and control samples sourced from the United Kingdom population.</p> <p>Methods</p> <p>DNA was extracted from blood samples and genetic data obtained by full sequence analysis of the prion protein gene or by restriction fragment length polymorphism analysis using restriction enzymes specific to the gene polymorphism under investigation.</p> <p>Results</p> <p>147 of 166 confirmed cases of variant CJD (vCJD) in the UK have had <it>PRNP </it>codon 129 genotyping and all are methionine homozygous at codon 129; 118 have had full <it>PRNP </it>gene sequencing. Of the latter, 5 cases have shown other polymorphic loci: at codon 219 (2, 1.69%), at codon 202 (2, 1.69%), and a 24 bp deletion in the octapeptide repeat region (1, 0.85%). E219K and D202D were not found in sporadic CJD (sCJD) cases and therefore may represent genetic risk factors for vCJD.</p> <p>Genetic analysis of 309 confirmed UK sCJD patients showed codon 129 genotype frequencies of MM: 59.5% (n = 184), MV: 21.4% (n = 66), and VV: 19.1% (n = 59). Thirteen (4.2%) had the A117A polymorphism, one of which also had the P68P polymorphism, four (1.3%) had a 24 bp deletion, and a single patient had a novel missense variation at codon 167. As the phenotype of this latter case is similar to sCJD and in the absence of a family history of CJD, it is unknown whether this is a form of genetic CJD, or simply a neutral polymorphism.</p> <p>Conclusions</p> <p>This analysis of <it>PRNP </it>genetic variation in UK CJD patients is the first to show a comprehensive comparison with healthy individuals (n = 970) from the same population, who were genotyped for the three most common variations (codon 129, codon 117, and 24 bp deletion). These latter two genetic variations were equally frequent in UK sCJD or vCJD cases and a normal (healthy blood donor) UK population.</p
