Can Action Research Strengthen District Health Management and Improve Health Workforce Performance? A Research Protocol.
The single biggest barrier for countries in sub-Saharan Africa (SSA) to scale up the necessary health services for addressing the three health-related Millennium Development Goals and achieving Universal Health Coverage is the lack of an adequate and well-performing health workforce. This deficit needs to be addressed both by training more new health personnel and by improving the performance of the existing and future health workforce. However, efforts have mostly been focused on training new staff and less on improving the performance of the existing health workforce. The purpose of this paper is to disseminate the protocol for the PERFORM project and reflect on the key challenges encountered during the development of this methodology and how they are being overcome. The overall aim of the PERFORM project is to identify ways of strengthening district management in order to address health workforce inadequacies by improving health workforce performance in SSA. The study will take place in three districts each in Ghana, Tanzania and Uganda using an action research approach. With the support of the country research teams, the district health management teams (DHMTs) will lead on planning, implementation, observation, reflection and redefinition of the activities in the study. Taking into account the national and local human resource (HR) and health systems (HS) policies and practices already in place, 'bundles' of HR/HS strategies that are feasible within the context and affordable within the districts' budget will be developed by the DHMTs to strengthen priority areas of health workforce performance. A comparative analysis of the findings from the three districts in each country will add new knowledge on the effects of these HR/HS bundles on DHMT management and workforce performance and the impact of an action research approach on improving the effectiveness of the DHMTs in implementing these interventions. Different challenges were faced during the development of the methodology. These include the changing context in the study districts, competing with other projects and duties for the time of district managers, complexity of the study design, maintaining the anonymity and confidentiality of study participants as well as how to record the processes during the study. We also discuss how these challenges are being addressed. The dissemination of this research protocol is intended to generate interest in the PERFORM project and also stimulate discussion on the use of action research in complex studies such as this on strengthening district health management to improve health workforce performance

Facility and home based HIV Counseling and Testing: a comparative analysis of uptake of services by rural communities in southwestern Uganda
<p>Abstract</p> <p>Background</p> <p>In Uganda, public human immunodeficiency virus (HIV) Voluntary Counseling and Testing (VCT) services are mainly provided through the facility based model, although the home based approach is being promoted as a strategy for improving access to VCT. However the uptake of VCT varies according to service delivery model and is influenced by a number of factors. The aim of this study therefore, was to compare predictors for uptake of facility and home based VCT in a rural context.</p> <p>Methods</p> <p>A longitudinal study with cross-sectional investigative phases was conducted at two sites (Rugando and Kabingo) in southwestern Uganda between November 2007 (baseline) and March 2008 (follow up). During the baseline visit, facility based VCT was offered at the main health centre in Rugando while home based VCT was offered at the household level in Kabingo and a mixed survey questionnaire administered to the respondents. The results presented in this paper are derived from only the baseline data.</p> <p>Results</p> <p>Nine hundred ninety four (994) respondents were interviewed, of whom 500 received facility based VCT in Rugando and 494 home based VCT in Kabingo during the baseline visit. The respondents had a mean age of 32.2 years (SD 10.9) and were mainly female (68 percent). Clients who received facility based VCT were less likely to be residents of the more rural households (adjusted Odds Ratio (aOR) = 0.14, 95% CI 0.07, 0.22). The clients who received home based VCT were less likely to report having an STI symptom (aOR = 0.63, 95% CI 0.46, 0.86), and more likely to be worried about discrimination if they contracted AIDS (aOR = 1.78, 95% CI 1.22, 2.61).</p> <p>Conclusion</p> <p>The uptake of VCT provided through either the facility or home based models is influenced by client characteristics such as proximity to service delivery points, HIV related symptoms, and fear of discrimination in rural Uganda. Interventions that seek to improve uptake of VCT should provide potential clients with both facility and home based VCT options within a given setting. The clients are then able to select a model for VCT that best fits their characteristics. This is likely to have positive implications for both service coverage and uptake by different sub-groups within particular communities.</p

Low-level regulatory T-cell activity is essential for functional type-2 effector immunity to expel gastrointestinal helminths
Helminth infection is frequently associated with the expansion of regulatory T cells (Tregs) and suppression of immune responses to bystander antigens. We show that infection of mice with the chronic gastrointestinal helminth Heligmosomoides polygyrus drives rapid polyclonal expansion of Foxp3(+)Helios(+)CD4(+) thymic (t)Tregs in the lamina propria and mesenteric lymph nodes while Foxp3(+)Helios(-)CD4(+) peripheral (p)Treg expand more slowly. Notably, in partially resistant BALB/c mice parasite survival positively correlates with Foxp3(+)Helios(+)CD4(+) tTreg numbers. Boosting of Foxp3(+)Helios(+)CD4(+) tTreg populations by administration of recombinant interleukin-2 (rIL-2):anti-IL-2 (IL-2C) complex increased worm persistence by diminishing type-2 responsiveness in vivo, including suppression of alternatively activated macrophage and granulomatous responses at the sites of infection. IL-2C also increased innate lymphoid cell (ILC) numbers, indicating that Treg functions dominate over ILC effects in this setting. Surprisingly, complete removal of Tregs in transgenic Foxp3-DTR mice also resulted in increased worm burdens, with "immunological chaos" evident in high levels of the pro-inflammatory cytokines IL-6 and interferon-γ. In contrast, worm clearance could be induced by anti-CD25 antibody-mediated partial depletion of early Treg, alongside increased T helper type 2 responses and without incurring pathology. These findings highlight the overarching importance of the early Treg response to infection and the non-linear association between inflammation and the prevailing Treg frequency
Urban coral reefs: Degradation and resilience of hard coral assemblages in coastal cities of East and Southeast Asia
© 2018 The Author(s) Given predicted increases in urbanization in tropical and subtropical regions, understanding the processes shaping urban coral reefs may be essential for anticipating future conservation challenges. We used a case study approach to identify unifying patterns of urban coral reefs and clarify the effects of urbanization on hard coral assemblages. Data were compiled from 11 cities throughout East and Southeast Asia, with particular focus on Singapore, Jakarta, Hong Kong, and Naha (Okinawa). Our review highlights several key characteristics of urban coral reefs, including “reef compression” (a decline in bathymetric range with increasing turbidity and decreasing water clarity over time and relative to shore), dominance by domed coral growth forms and low reef complexity, variable city-specific inshore-offshore gradients, early declines in coral cover with recent fluctuating periods of acute impacts and rapid recovery, and colonization of urban infrastructure by hard corals. We present hypotheses for urban reef community dynamics and discuss potential of ecological engineering for corals in urban areas

Cost effectiveness of facility and home based HIV voluntary counseling and testing strategies in rural Uganda
Background: In Uganda, the main stay for provision of human
immunodeficiency virus (HIV) voluntary counseling and testing (VCT) has
been at health facilities. Home based VCT on the other hand, was
initiated in the country to improve service coverage. Objective: To
evaluate the cost effectiveness of facility- and home-based HIV VCT
strategies in rural southwestern Uganda. Methods: Data on costs and
effectiveness of facility- and home-based HIV VCT intervention
strategies was collected in two sub-Counties in rural southwestern
Uganda. Costing was performed using the ingredients approach.
Effectiveness was measured as the number of HIV sero-positive clients
identified. Incremental Cost-Effectiveness Ratios (ICERs) were
calculated from the provider perspective. Results: The cost per client
tested were US5.0 for home based
VCT. The corresponding costs per positive case identified were US54.7 respectively. The incremental cost to providers per
additional positive case identified by facility based VCT was US$3.5.
Conclusion: Home based VCT was the least costly strategy per client
tested and was also cost effective in identifying HIV sero-positive
clients in rural areas. This strategy should therefore be promoted to
improve service coverage and thereby facilitate early and extensive
detection of clients eligible for treatment
Self reported risk reduction behavior associated with HIV testing and counseling: A comparative analysis of facility- and home-based models in rural Uganda
Home-based human immunodeficiency virus (HIV) voluntary counseling and testing (VCT) in Uganda is being promoted to increase coverage, in addition to main stay approach of service provision through health facilities. The aim of this study was to compare self reported risk reduction behavior among clients receiving facility and home-based HIV VCT within a rural context. Pre-post intervention client surveys were conducted in November 2007 (baseline) and March 2008 (follow up) in southwestern Uganda. The facility-based VCT intervention was provided to 500 clients and home-based VCT to 494 clients at baseline, in 2 different sub-counties. A total of 76% (759/994) of these clients were interviewed at the follow up visit. The respondents who received facility-based VCT were more likely to report abstinence (adjusted Odds Ratio [aOR]=1.47, 95% CI 1.074, 2.02), reducing multi sexual relationships (aOR=3.23, 95% CI 2.02, 5.16) and more frequent use of condoms (aOR=3.14, 95% CI 1.60, 6.18). However, they were less likely to report, discussing HIV (aOR=0.63, 95% CI 0.46, 0.85) with their sexual partner/s and having sex with only one partner (aOR=0.72, 95% CI 0.519–0.99). While facility-based VCT appears to promote abstinence and condom use, home-based VCT on the other hand promotes faithfulness and disclosure. VCT services should, therefore, be provided through both models in a complementary relationship and not as surrogates within given settings
