Personal and Financial Risk Typologies Among Women Who Engage in Sex Work in Mongolia: A Latent Class Analysis

Women engaged in sex work bear a disproportionate burden of HIV infection worldwide, particularly in low- to middle-income countries. Stakeholders interested in promoting prevention and treatment programs are challenged to efficiently and effectively target heterogeneous groups of women. This problem is particularly difficult because it is nearly impossible to know how those groups are composed a priori. Although grouping based on individual variables (e.g., age or place of solicitation) can describe a sample of women engaged in sex work, selecting these variables requires a strong intuitive understanding of the population.Furthermore, this approach is difficult to quantify and has the potential to reinforce preconceived notions, rather than generate new information. We aimed to investigate groupings of women engaged in sex work. The data were collected from a sample of 204 women who were referred to an HIV prevention intervention in Ulaanbaatar, Mongolia. Latent class analysis was used to create subgroups of women engaged in sex work, based on personal and financial risk factors.This analysis found three latent classes, representing unique response pattern profiles of personal and financial risk. The current study approached typology research in a novel, more empirical way and provided a description of different subgroups, which may respond differently to HIV risk interventions

Challenges Facing Community Home Based Care Programmes in Botswana

This study examines the role of Community Home-Based Care in Botswana for people with HIV/AIDS and those with other terminal illnesses. Kerkhoven and Jackson (1995) attribute the popularity of Community Home-Based Care (CHBC) programmes in the developing countries to high rates of HIV/AIDS. Botswana has adult HIV/AIDS prevalence rate of 37 per cent and over 350,000 people living with HIV/AIDS. Rapid rise in incidences of HIV/AIDS has hence resulted in increasing need for CHBC and thus many CHBC services have been established through disorganized and fragmented manners. This paper is an extended literature review. It identifies and discusses challenges facing CHBC programmes in Botswana. The findings indicate that poverty, high cost of community care, inadequate medical facilities, poor infrastructures and socio-cultural issues have threatened the sustainability of CHBC programmes in Botswana. Recommendations and policy options are discussed.East African Social Science Research Review Vol. 23 (2) 2007: pp. 1-1

Because of the large number of total knee replacement (TKR) surgeries conducted per year, and with projections of increased demand to almost a million primary TKR surgeries per year by 2030 in the United States alone, there is a need to discover more efficient working materials as alternatives to current bone cements. There is a need for surgeons and hospitals to become more efficient and better control over the operative environment. One area of inefficiency is the cement steps during TKR. Currently the surgeon has very little control over cement polymerization. This leads to an increase in time, waste, and procedural inefficiencies. There is a clear need to create an extended working time, moldable, osteoconductive, and osteoinductive bone augment as a substitution for the current clinically used bone cement where the surgeon has better control over the polymerization process. This study explored several compositions of pentaerythritol-co-trimethylolpropane tris-(3-mercaptopropionate) hydroxyapatite composite materials prepared via benzoyl peroxide-initiated thermal frontal polymerization. The 4:1 acrylate to thiol ratio containing augment material shows promise with a maximal propagation temperature of 160°C ± 10°C, with mechanical strength of 3.65 MPa, and 111% cytocompatibility, relative to the positive control. This frontally polymerized material may have application as an augment with controlled polymerization supporting cemented implants
