Directly observed road safety compliance by Motor Cycle Riders after a 5- Year Road Safety Campaign in Naivasha, Kenya

Objective: To assess the extent of compliance with road safety regulations by  motorcycle riders following a five year road safety campaign in Naivasha town, Kenya.Design: A cross sectional study.Setting: Naivasha town, Nakuru county, Kenya.Results: A total of 9,280 MCs ferrying 13,733 people were observed. Less than 1% complied with all the four road safety  requirements. The overall helmet wearing compliance was 31%. MC driver helmet compliance was 42% which was five timeshigher than passenger helmet compliance. Female passengers were twice less likely to wear helmet than males.Conclusion: Despite the five-year road safety campaign, compliance among MC users remains low particularly among the passengers and more so female passengers. Does Kenya need to rethink the motor cycle road safety policy

Association between thrombocytes count and Plasmodium falcipurum infection among children under five years attending Kombewa Sub-County Hospital

Malaria is a leading cause of morbidity and mortality especially among children, expectant women and continues to be a global health burden. Haematological changes mark some of the most common complications in malaria as they play a major role in malaria pathology. Thrombocytes in particular, have been shown to bind infected erythrocytes and kill intracellular malaria parasites thereby indicating a protective function of platelets in the early stages. However, the mechanism that leads to low thrombocytes count in malaria infected individuals is not clear. Understanding the mechanism of platelet reduction during pathogenesis of malaria infection will be fundamental in malaria severity classification, monitoring of platelet count during infection and prompt initiation of anti-malarial therapy. In trying to understand these facts, this study sort to establish the association between platelet count and P. falciparum infection amongst children less than five years. This was a retrospective case-control study, n=549. Children below the age of five years that attending Kombewa Sub -County Hospital were recruited. Study participants were identified using the inclusion criteria and followed horizontally to retrieve platelet count from complete blood count results. The respective malaria blood film reads were then recorded, stratified to give case and control from which random sampling was done. Chi-square test and Tukey’s multiple comparison tests from Graph pad prism 5 were used in the analysis. The odds of exposure to low platelet count were then established with a confidence level of 95%. We found significant difference between the cases and controls in regard to parasite density (Chi square=157.5, p value <0.05), mean parasite density in controls =2042.1/?l compared to cases= 142880/?l. The odds of cases being exposed to malaria was 12 times more than controls (OR=12.382, 95%). We also found no variation in thrombocytes counts in relation to gender, children with thrombocytopenia were having higher parasite density, parasite density as a result of P.falciparum infection is not dependent on gender and children that suffered malarial infection were twelve times likely to develop thrombocytopenia. Further studies are then recommended to establish the effects of incorporation of platelet aggregation inhibitors such as aspirin in malaria treatment.Key Words: Plasmodium falciparum, thrombocytopenia, infectio

Determinants of Agricultural Information Access by Small Holder Tea Farmers in Bureti District

Abstract: The study aims at determining factors affecting the access to agricultural information by smallholder tea farmers. Tea sub-sector is Kenya's second largest foreign exchange earner after horticulture. The small holder farmers own about 80% of the land under tea but produce about 60% of made tea thus realizing less yield per unit area as compared to their large scale counterparts. Tea Research Foundation of Kenya in conjunction with the Ministry of Agriculture has developed several technologies aimed at improving both yield and quality of tea. The technologies include high yielding clones; selective application of herbicides; insect, pest and weed control; fertilizer recommendation rates and harvesting practices. Small holder farmers however continue to realize low declining crop yields. It is generally known that access to information is a potential avenue for increasing yield. A study was carried out to determine access to information by smallholder tea farmers in Bureti District, Kenya. A combination of purposive, multistage and proportionate random sampling was used to get 170 respondents. Data collected was managed using Statistical Package for Social Sciences (SPSS) version 15 and Probit Model was used to estimate the parameters that determined access to information. Off-farm income, education level, household size, marital status and time spent at tea buying center significantly influenced access to information by small holder tea farmers. The study in conclusion emphasized the need of information to small holder tea farmers so as to facilitate increased yield

A Retrospective Survey of HIV Drug Resistance Among Patients 1 Year After Initiation of Antiretroviral Therapy at 4 Clinics in Malawi

In 2004, Malawi began scaling up its national antiretroviral therapy (ART) program. Because of limited treatment options, population-level surveillance of acquired human immunodeficiency virus drug resistance (HIVDR) is critical to ensuring long-term treatment success. The World Health Organization target for clinic-level HIVDR prevention at 12 months after ART initiation is ≥ 70%. In 2007, viral load and HIVDR genotyping was performed in a retrospective cohort of 596 patients at 4 ART clinics. Overall, HIVDR prevention (using viral load ≤ 400 copies/mL) was 72% (95% confidence interval [CI], 67%-77%; range by site, 60%-83%) and detected HIVDR was 3.4% (95% CI, 1.8%-5.8%; range by site, 2.5%-4.7%). Results demonstrate virological suppression and HIVDR consistent with previous reports from sub-Saharan Africa. High rates of attrition because of loss to follow-up were noted and merit attention

Not All Missed Doses Are the Same: Sustained NNRTI Treatment Interruptions Predict HIV Rebound at Low-to-Moderate Adherence Levels

Background: While the relationship between average adherence to HIV potent antiretroviral therapy is well defined, the relationship between patterns of adherence within adherence strata has not been investigated. We examined medication event monitoring system (MEMS) defined adherence patterns and their relation to subsequent virologic rebound. Methods and Results: We selected subjects with at least 3-months of previous virologic suppression on a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimen from two prospective cohorts in France and North America. We assessed the risk of virologic rebound, defined as HIV RNA of >400 copies/mL according to several MEMS adherence measurements. Seventy two subjects were studied, five of them experienced virologic rebound. Subjects with and without virologic rebound had similar baseline characteristics including treatment durations, regimen (efavirenz vs nevirapine), and dosing schedule. Each 10% increase in average adherence decreased the risk of virologic rebound (OR = 0.56; 95% confidence interval (CI) [0.37, 0.81], P<0.002). Each additional consecutive day off therapy for the longest treatment interruption (OR = 1.34; 95%CI [1.15, 1.68], P<0.0001) and each additional treatment interruption for more than 2 days (OR = 1.38; 95%CI [1.13, 1.77], P<0.002) increased the risk of virologic rebound. In those with low-to-moderate adherence (i.e. <80%), treatment interruption duration (16.2 days versus 6.1 days in the control group, P<0.02), but not average adherence (53.1% vs 55.9%, respectively, P = 0.65) was significantly associated with virologic rebound. Conclusions: Sustained treatment interruption may pose a greater risk of virologic rebound on NNRTI therapy than the same number of interspersed missed doses at low-to-moderate adherence

Adherence Support Workers: A Way to Address Human Resource Constraints in Antiretroviral Treatment Programs in the Public Health Setting in Zambia

BACKGROUND: In order to address staff shortages and improve adherence counseling for people on antiretroviral therapy (ART), the Zambia Prevention, Care and Treatment Partnership (ZPCT) developed an innovative strategy of training community volunteers to provide adherence support at the health facility and community levels. The objective of this study was to assess the effectiveness of these 'adherence support workers' (ASWs) in adherence counseling, treatment retention and addressing inadequate human resources at health facilities.METHODOLOGY/PRINCIPAL FINDINGS: The study used quantitative and qualitative research techniques at five selected ART sites in four provinces in Zambia. Five hundred patients on ART were interviewed using a structured questionnaire to compare the quality of adherence counseling before and after the ASW scheme was introduced at the selected sites and between ASWs and HCWs after the introduction of ASWs. In addition, 3,903 and 4,972 electronic records of all new patients accessing antiretroviral therapy for the time period of 12 months before and 12 months after the introduction of ASWs respectively, were analyzed to assess loss to follow-up rates. Two focus group discussions with ASWs and health care workers (HCWs) were conducted in each clinic. Key informant interviews in the ART clinics were also conducted. There was a marked shift of workload from HCWs to ASWs without any compromise in the quality of counseling. Quality of adherence counseling by ASWs was comparable to HCWs after their introduction. The findings suggest that the deployment of ASWs helped reduce waiting times for adherence counseling. Loss to follow-up rates of new clients declined from 15% to 0% after the deployment of ASWs.CONCLUSION: Adherence counseling tasks can be shifted to lay cadres like ASWs without compromising the quality of counseling. Follow-up of clients by ASWs within the community is necessary to improve retention of clients on ART

Correcting for Mortality Among Patients Lost to Follow Up on Antiretroviral Therapy in South Africa: A Cohort Analysis

Loss to follow-up (LTF) challenges the reporting of antiretroviral treatment (ART) programmes, since it encompasses patients alive but lost to programme and deaths misclassified as LTF. We describe LTF before and after correction for mortality in a primary care ART programme with linkages to the national vital registration system

Higher quality of life and lower depression for people on art in Uganda as compared to a community control group

Provision of antiretroviral treatment (ART) to people living with HIV (PLWH) has increased globally. Research measuring whether ART restores subjective well-being to "normal" levels is lacking, particularly in resource limited settings. The study objectives are to compare quality of life and depression symptoms for PLWH on ART to a general community population and to explore factors to explain these differences, including socio-economic status and the impact of urban or rural residence. PLWH on ART (n = 263) were recruited from ART delivery sites and participants not on ART (n = 160) were recruited from communities in Wakiso District, Uganda. Participants were interviewed using the translated World Health Organisation Quality of Life brief measure, the Hopkins Symptom Checklist depression section, and questions about socioeconomic status, residence as urban or rural and, for PLWH on ART, self-reported adherence and use of HIV counselling. Compared to the community sample and controlling for location of residence, PLWH on ART had significantly higher quality of life (QOL) for physical, psychological and environment domains, but not the social domain. These differences were not due to socio-economic status alone. Depression scores were significantly lower for PLWH on ART. Both comparisons controlled for the effect of location of residence. People on ART self-reported high adherence and the majority had used HIV counselling services. Our findings show better QOL amongst PLWH on ART compared to a general community sample, which cannot be explained solely by differences in socio-economic status nor location of residence. The general community sample results point towards the challenges of life in this setting. Access to health services may underpin this difference and further research should explore this finding, in addition to identification of psychological mechanisms that relate to better QOL. ART provision infrastructure has clear benefits. Further work should consider sustainability and replication for other health conditions. © 2014 Martin et al
