Smartphone Use in Financial Management among Women’s Informal Saving Groups in Dodoma, Tanzania

Diffusion of smartphone technology has created multiple opportunities for economic development. This research investigated the use of smartphones in financial management among women’s informal saving groups in Dodoma, Tanzania. Qualitative data were collected from 10 groups, derived from 15 interviews and 3 focus group discussions (FGDs) with 22 participants and thematic analysis was done. The findings revealed that research participants were using smartphones to access WhatsApp, the camera, mobile money applications and the calculator for coordination, recording, calculation, and payment. It was also found that untrustworthy communications, high charges and mobile fraud were challenges experienced by the groups. Familiarity, ease of use and nature of the group were identified as important reasons for the smartphone use in financial management. The research contributes knowledge regarding digitizing informal saving groups although smartphone use was not strongly linked to financial management success. This suggests a need for improved skills and technological empowerment to achieve sustainable growth

Durability associated efficacy of long-lasting insecticidal nets after five years of household use

<p>Abstract</p> <p>Background</p> <p>Long-lasting insecticidal nets (LLINs) have been strongly advocated for use to prevent malaria in sub-Saharan Africa and have significantly reduced human-vector contact. PermaNet^®2.0 is among the five LLINs brands which have been given full approval by the WHO Pesticide Evaluation Scheme (WHOPES). The LLINs are expected to protect the malaria endemic communities, but a number of factors within the community can affect their durability and efficacy. This study evaluated the durability, efficacy and retention of PermaNet^®2.0 after five years of use in a Tanzanian community.</p> <p>Method</p> <p>Two to three day- old non blood-fed female mosquitoes from an insectary susceptible colony (<it>An. gambiae </it>s.s, this colony was established at TPRI from Kisumu, Kenya in 1992) and wild mosquito populations (<it>An. arabiensis </it>and <it>Culex quinquefasciatus</it>) were used in cone bioassay tests to assess the efficacy of mosquito nets.</p> <p>Findings</p> <p>The knockdown effect was recorded after three minutes of exposure, and mortality was recorded after 24 hours post-exposure. Mortality of <it>An. gambiae </it>s.s from insectary colony was 100% while <it>An. arabiensis </it>and <it>Cx.quinquefasciatus </it>wild populations had reduced mortality. Insecticide content of the new (the bed net of the same brand but never used before) and used PermaNet^®2.0 was determined using High Performance Liquid Chromatography (HPLC).</p> <p>Conclusion</p> <p>The results of this study suggest that, in order to achieve maximum protection against malaria, public health education focusing on bed net use and maintenance should be incorporated into the mass distribution of nets in communities.</p

Assessing the effect of insecticide-treated cattle on tsetse abundance and trypanosome transmission at the wildlife-livestock interface in Serengeti, Tanzania

In the absence of national control programmes against Rhodesian human African trypanosomiasis, farmer-led treatment of cattle with pyrethroid-based insecticides may be an effective strategy for foci at the edges of wildlife areas, but there is limited evidence to support this. We combined data on insecticide use by farmers, tsetse abundance and trypanosome prevalence, with mathematical models, to quantify the likely impact of insecticide-treated cattle. Sixteen percent of farmers reported treating cattle with a pyrethroid, and chemical analysis indicated 18% of individual cattle had been treated, in the previous week. Treatment of cattle was estimated to increase daily mortality of tsetse by 5–14%. Trypanosome prevalence in tsetse, predominantly from wildlife areas, was 1.25% for T. brucei s.l. and 0.03% for T. b. rhodesiense. For 750 cattle sampled from 48 herds, 2.3% were PCR positive for T. brucei s.l. and none for T. b. rhodesiense. Using mathematical models, we estimated there was 8–29% increase in mortality of tsetse in farming areas and this increase can explain the relatively low prevalence of T. brucei s.l. in cattle. Farmer-led treatment of cattle with pyrethroids is likely, in part, to be limiting the spill-over of human-infective trypanosomes from wildlife areas

Design of an Interactive Mobile Application for Maternal, Neonatal and Infant Care Support for Tanzania

This research article published by Scientific Research Publishing, 2018Reducing maternal and infant deaths’ rates in the developing countries, particularly in sub-Sahara Africa, remain a big challenge. Despite efforts by governments, the reductions have been unsatisfactory. To accelerate the reduction in maternal and infant deaths, m-health has been proposed as a viable, economical and effective intervention, able to reach the low income and disadvantaged groups. Mobile phone-based applications are among the m-health interventions that have been found to have positive outcomes for different healthcare challenges, such as improving clinical attendance and skilled delivery, and reducing perinatal mortality. However, the adoption of smartphone-based applications for health in Tanzania has been slow. Some of the likely contributing factors might be low technology exposure by the majority of the population and English language skills’ limitations. In this work, we developed a mobile application for providing interactive support to users, thus complementing other solutions available such as SMS and other smartphone apps. The main advantage of this app is the presence of interactive features that enable patient-provider communication. We adopted the Rapid application development (RAD) model for developing the application. We used UML modeling language tools for designing the application. The mobile application’s technical architecture uses various technologies and system development tools such as PHP programming language for the web application, MySQL database manag

Surgical treatment options and its adverse outcomes among patients with urolithiasis at KCMC, 2014 to 2018

Purpose: The study aimed to evaluate surgical treatment options and its adverse outcomes among patients with urolithiasis at Kilimanjaro Christian Medical Centre (KCMC). All patients who were diagnosed with urolithiasis and underwent surgical intervention from January 2014 to December 2018 were enrolled.Method and material: This was a hospital based descriptive cross-sectional study conducted at the institute of urology, KCMC, Moshi, Tanzania. Urology theatre registry was used to obtain patients’ registration numbers then the files were retrieved from medical records. Relevant information was extracted using structured data collection tool. STATA version 14.1 was used for analysis and a P value of 0.05 was regarded to be statistically significant.Results: Among seventy-eight subjects, sixty-two were males and sixteen were females with male to female ratio of 3.8:1. Patients aged 4 years to 90 years. Majority 57 (73.1%) underwent open surgery treatment and only 17 (21.8%) had adverse outcome after treatment. In multivariate analysis patients treated with endoscopy had more than six times higher odds of adverse outcomes compared to counterpart though this was not statistically significant (OR: 6.65; 95% CI: 0.82, 53.87)Conclusion: Open surgeries have been observed to have better outcome compared to endoscopy surgeries among urolithiasis patients as most of the adverse outcomes were more observed among patients treated with endoscop

A tsetse Glossina pallidipes harbors the pathogenic trypanosomes circulating in Liwale district, Tanzania

Veterinary Parasitology: Regional studies and reports 9 (2017) 93-97African Animal Trypanosomiasis (AAT) is among several constraints hindering development of the livestock sector in Tanzania. A survey was conducted in Liwale district located in southern Tanzania in 2013 to determine the population density of Glossina species, distribution pattern and Trypanosome species infection rate in tsetse flies. A total of 200 flies were collected from the study area and three Glossina species were identified. The proportional abundance of all trapped flies was 90% (180) for Glossina pallidipes, 6% (12) for G. brevipalpis and 4% (8) for G. m. morsitans with apparent densities (fly/trap/day - FTD) of 0.44. Higher density of Glossina pallidipes was observed in villages closer to than those far from the Selous game reserve. Trypanosomes were detected and identified by microscopy and ITS1 polymerase chain reaction (PCR) assay on DNA purified from 200 flies. Glossina pallidipes was the only fly found infected by three Trypanosoma species, namely T. vivax (60%), T. simiae (10%) and T. brucei (30%) with an overall infection rate of 10% (20/200). A higher proportion of trypanosome infections were observed in female tsetse flies than in males. Results of this study show that G pallidipes is the major Glossina species harboring pathogenic trypanosomes in Liwale district and that the Selous game reserve is a potential reservoir of trypanosomes in terms of parasite abundance and species diversity.COSTEC

Generating Improved Experimental Designs with Spatially and Genetically Correlated Observations Using Mixed Models

The aim of this study was to generate and evaluate the efficiency of improved field experiments while simultaneously accounting for spatial correlations and different levels of genetic relatedness using a mixed models framework for orthogonal and non-orthogonal designs. Optimality criteria and a search algorithm were implemented to generate randomized complete block (RCB), incomplete block (IB), augmented block (AB) and unequally replicated (UR) designs. Several conditions were evaluated including size of the experiment, levels of heritability, and optimality criteria. For RCB designs with half-sib or full-sib families, the optimization procedure yielded important improvements under the presence of mild to strong spatial correlation levels and relatively low heritability values. Also, for these designs, improvements in terms of overall design efficiency (ODE%) reached values of up to 8.7%, but these gains varied depending on the evaluated conditions. In general, for all evaluated designs, higher ODE% values were achieved from genetically unrelated individuals compared to experiments with half-sib and full-sib families. As expected, accuracy of prediction of genetic values improved as levels of heritability and spatial correlations increased. This study has demonstrated that important improvements in design efficiency and prediction accuracies can be achieved by optimizing how the levels of a treatment are assigned to the experimental units
