English as a Second Language in Up With People: A Proposal and Plan for Implementation

The purpose of this paper is to provide the Up With People organization with a clear and workable plan for implementing an English as a Second Language program as a part of their existing program. The paper is presented in two parts. The first part includes a description of the Up With People program focusing on its need for an English as a Second Language program. The various benefits to UP With People are explained. Also in the first part of the paper are descriptions of two language learning programs, Spanish Language Training at Oaxtepec, Mexico, July, 1980, and The International Students of English program at Dominican College, San Rafael, California. Elements of these programs which are usable to UP With People are explained. The second part of the paper is a plan for implementation, carefully following the schedule and design of Up With People, and paying attention to the utilization of the language learning benefits already a part of the Up With People program. Areas covered include: scheduling, staffing, curriculum, materials, and a tentative budget outline

Treatment to Prevent Transmission of HIV‐1

Antiretroviral agents (ART) have the potential to prevent HIV transmission by reducing the concentration of HIV in blood and genital secretions. Indeed, mathematical models with favorable assumptions suggest the potential of ART to stop the spread of HIV. Empirical results from ecological and population based studies, and several short term observational studies involving HIV discordant heterosexual couples suggest that ART reduces HIV transmission. A multinational randomized controlled trial (NIH NPTN052) also examining the reliability and durability of ART as prevention in HIV discordant couples is underway. The latter and other studies also consider sexual risk taking behavior, and transmission of HIV resistant variants when ART is used as prevention. Early HIV detection and treatment (“test and treat”) are being considered as an important prevention strategy. In this article, we review the data supporting the use of ART to prevent HIV transmission, and critically examine the public health implications of this strategy

Phase 1 Clinical Trial of Trametes versicolor in Women with Breast Cancer

Introduction. Orally administered preparations from the Trametes versicolor (Tv) mushroom have been hypothesized to improve immune response in women with breast cancer after standard chemotherapy and radiotherapy. Methods. A phase I, two-center, dose escalation study was done to determine the maximum tolerated dose of a Tv preparation when taken daily in divided doses for 6 weeks after recent completion of radiotherapy. Eleven participants were recruited and nine women completed the study. Each cohort was comprised of three participants given one of three doses of Tv (3, 6, or 9 grams). Immune data was collected pre- and postradiation, at 3 on-treatment time points and after a 3-week washout. Results. Nine adverse events were reported (7 mild, 1 moderate, and 1 severe), suggesting that Tv was well tolerated. Immunological results indicated trends in (1) increased lymphocyte counts at 6 and 9 grams/day; (2) increased natural killer cell functional activity at 6 grams/day; (3) dose-related increases in CD8+ T cells and CD19+ B cells , but not CD4+ T cells or CD16+56+ NK cells. Conclusion. These findings show that up to 9 grams/day of a Tv preparation is safe and tolerable in women with breast cancer in the postprimary treatment setting. This Tv preparation may improve immune status in immunocompromised breast cancer patients following standard primary oncologic treatment

Vorinostat Renders the Replication-Competent Latent Reservoir of Human Immunodeficiency Virus (HIV) Vulnerable to Clearance by CD8 T Cells

Latently human immunodeficiency virus (HIV)-infected cells are transcriptionally quiescent and invisible to clearance by the immune system. To demonstrate that the latency reversing agent vorinostat (VOR) induces a window of vulnerability in the latent HIV reservoir, defined as the triggering of viral antigen production sufficient in quantity and duration to allow for recognition and clearance of persisting infection, we developed a latency clearance assay (LCA). The LCA is a quantitative viral outgrowth assay (QVOA) that includes the addition of immune effectors capable of clearing cells expressing viral antigen. Here we show a reduction in the recovery of replication-competent virus from VOR exposed resting CD4 T cells following addition of immune effectors for a discrete period. TAKE HOME MESSAGE: VOR exposure leads to sufficient production of viral protein on the cell surface, creating a window of vulnerability within this latent reservoir in antiretroviral therapy (ART)-suppressed HIV-infected individuals that allows the clearance of latently infected cells by an array of effector mechanisms

Sexual and reproductive health outcomes among female sex workers in Johannesburg and Pretoria, South Africa: Recommendations for public health programmes

Abstract Background The sexual and reproductive health (SRH) status of female sex workers is influenced by a wide range of demographic, behavioural and structural factors. These factors vary considerably across and even within settings. Adopting an overly standardised approach to sex worker programmes may compromise its impact on some sub-groups in local areas. Methods Records of female sex workers attending clinic-, community-, or hotel-based health services in Johannesburg (n = 1422 women) and Pretoria (n = 408 women), South Africa were analysed. We describe the population’s characteristics and identified factors associated with sexual and reproductive health outcomes, namely HIV status; previous symptomatic sexually transmitted infection (STI); modern contraceptive use and number of child dependents. Results The women in Johannesburg were less likely than those in Pretoria to have HIV (42.2% vs 52.9%), or previous symptomatic STIs (44.3% vs. 8.3%), and were 1.4 fold less likely to have child dependents (20.1% vs. 15.3%). About 43% of women in Johannesburg were Zimbabwean and 40% in Pretoria. Of concern, only about 15% of women in both sites were using modern contraceptives. Johannesburg women were also more likely to access health services at a hotel (85.0% vs. 80.6%) or clinic (5.7% vs. 0.5%), to have completed secondary education (57.1% vs. 36.0%), and moved house more than twice during the past year (19.6 vs. 2.0%). In both cities, risk of HIV rose rapidly with age (23.8%–58.2% vs. 22.0%–64.8%). Of interest, HIV prevalence was considerably higher in those with consistent condom use with one’s main partner than inconsistent users. Conclusions Sex worker populations are heterogeneous. Local health programmes must prioritise services that reflect the variety and complexity of sex worker needs and behaviours, and should be designed in consultation with sex workers. Segmenting sex worker populations according to age, country of origin and place of service delivery, and training healthcare providers accordingly, could help prevent new HIV infections, improve adherence to antiretroviral treatment and increase uptake of SRH services

Interval dosing with the HDAC inhibitor vorinostat effectively reverses HIV latency

BACKGROUND. The histone deacetylase (HDAC) inhibitor vorinostat (VOR) can increase HIV RNA expression in vivo within resting CD4+ T cells of aviremic HIV+ individuals. However, while studies of VOR or other HDAC inhibitors have reported reversal of latency, none has demonstrated clearance of latent infection. We sought to identify the optimal dosing of VOR for effective serial reversal of HIV latency

Patterns of periodontal disease progression based on linear mixed models of clinical attachment loss

AimThe goal of the present longitudinal cohort study was to examine patterns of periodontal disease progression at progressing sites and subjects defined based on linear mixed models (LMM) of clinical attachment loss (CAL).Materials and MethodsA total of 113 periodontally healthy and 302 periodontitis subjects had their CAL calculated bimonthly for 12 months. LMMs were fitted for each site and the predicted CAL levels used to categorize their progression state. Participants were grouped based on the number of progressing sites into unchanged, transitional and active subjects. Patterns of periodontal disease progression were explored using descriptive statistics.ResultsProgression occurred primarily at molars (50% of progressing sites) and inter‐proximal sites (72%), affected a higher proportion of deep than shallow sites (2.7% versus 0.7%), and pocketing was the main mode of progression (49%). We found a low level of agreement (47%) between the LMM and traditional approaches to determine progression such as change in CAL ≥3 mm. Fourteen per cent of subjects were classified as active and among those 93% had periodontitis. The annual mean rate of progression for the active subjects was 0.35 mm/year.ConclusionProgressing sites and subjects defined based on LMMs presented patterns of disease progression similar to those previously reported in the literature.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/142020/1/jcpe12827.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/142020/2/jcpe12827_am.pd

Erythromycin-nonsusceptible Streptococcus pneumoniae in Children, 1999–2001

After increasing from 1995 to 1999, invasive erythromycin-nonsusceptible Streptococcus pneumoniae rates per 100,000 decreased 53.6% in children from Baltimore, Maryland (US), from 1999 to 2001, which was partially attributed to strains related to the mefE-carrying England14-9 clone. The decline in infection rates was likely due to the pneumococcal 7-valent conjugate vaccine

Initiating antiretroviral therapy when presenting with higher CD4 cell counts results in reduced loss to follow-up in a resource-limited setting

OBJECTIVE: In August 2011, South Africa expanded its adult antiretroviral therapy (ART) guidelines to allow treatment initiation at CD4 cell values 350 cells/μl or less. Mortality and morbidity are known to be reduced when initiating at higher CD4 levels; we explored the impact on patient loss to follow-up. DESIGN: An observational cohort study. METHODS: We analyzed routine data of 1430 adult patients initiating ART from April to December 2010 from a Johannesburg primary healthcare clinic offering ART initiation at CD4 cell count 350 cells/μl or less since 2010. We compared loss to follow-up (≥3 months late for the last scheduled visit), death, and incident tuberculosis within 1 year of ART initiation for those initiating at CD4 cell values 200 or less versus 201-350 cells/μl. RESULTS: : Half (52.0%) of patients presented in the lower CD4 cell group [≤200 cells/μl, median: 105 cells/μl, interquartile range (IQR): 55-154] and initiated ART, and 48.0% in the higher group (CD4 cell count 201-350 cells/μl, median: 268 cells/μl, IQR: 239-307). The proportion of women and pregnant women was greater in the high CD4 cell group; the lower CD4 cell group included more patients with prevalent tuberculosis. Among men and nonpregnant women, initiating at 201-350 cells/μl was associated with 26-42% reduced loss to follow-up compared to those initiating 200 cells/μl or less. We found no CD4 cell effect among pregnant women. Risk of mortality [adjusted hazard ratio (aHR) 0.34, 95% confidence interval (CI) 0.13-0.84] and incident tuberculosis (aHR 0.44, 95% CI 0.23-0.85) was lower among the higher CD4 cell group. CONCLUSION: This is one of the first studies from a routine clinical setting to demonstrate South Africa's 2011 expansion of ART treatment guidelines can be enacted without increasing program attrition
