Wash practices assessment on the nutrition status of children under age five in Songwe region: A case study of Ileje District Council

The study aims to assess the effects of water, sanitation and hygiene practices on the nutrition status of children under five years in the Songwe region of Tanzania since malnutrition is still a big challenge in developing countries, particularly the Southern Highlands Zone which needs integrated measures to be addressed. Cross-sectional studies involving 110 children aged 0-59 months were assessed for Weight-for-Age, Height-for-Age and Weight-for-Height involving a structured questionnaire. Results showed that 47.27% were stunted, 27.27% were underweight while 16.36% were wasted and 53.63% of respondents did not participate in any community program. The study also revealed that 35.45% had pit latrines, 44.54% used communal pit latrines, 13.63% had flush toilet types and 6.36% did not have any kind of toilet. Lack of proper latrine increases the chances of getting infections such as worm infestation. 37.27% of respondents still use unimproved sources (River water, dams, ponds) and 65.45% of respondents use untreated water for drinking, cooking, and food preparation activities which increases disease incidences and infections. The presence of poor nutrition status of children under age five in the study sample was caused by poor childcare practices. These findings alert the Government starting from the local government level to use nutrition stakeholders to effectively influence mothers/caregivers to make healthy dietary practices

Investigating School Experiences of Vulnerable Children in Singida, Tanzania: Challenges, Strategies, and Possible Interventions

The number of vulnerable children in Tanzania is on the rise. For the purpose of this study, the concept of vulnerable children refers to those who are under18 whose life is in jeopardy due to socio-economic factors such as: abject poverty, orphanhood, and child abandonment, among others. Although vulnerability is known to have deleterious impacts on students\u27 learning, studies conducted in Tanzanian schools on the issue of vulnerable children\u27s education are scarce. Consequently, this research sought to: (a) examine vulnerable children\u27s school experiences in Singida from the perspective of educators and vulnerable children alike; (b) explore challenges facing educators who strive to meet vulnerable children\u27s academic needs; and (c) investigate strategies that teachers and schools can implement to support and scaffold vulnerable children\u27s learning and improve quality of education. The study employed a qualitative research methodology and critical ethnographic approach. Participants were drawn from 5 schools and a centre for orphaned and vulnerable children located in Singida region, Tanzania, and included 5 school principals, 45 teachers, and 26 children. Data was collected via participatory observations, in-depth individual interviews, focus group discussions and questionnaires. The results of this study indicated that the vulnerable children in Singida who participated in this study generally experienced schools as a stumbling block. Recommendations are made for urgent intervention by government leaders, policy makers and educators to support the schools through improved work conditions, enhanced school leadership and pedagogy, teacher development programs, collective ownership of the problem and commitment to ensuring improved school experiences for vulnerable children

Temporal fluctuations in the sero-prevalence of <i>Taenia solium</i> cysticercosis in pigs in Mbeya Region, Tanzania

BACKGROUND: Porcine cysticercosis is an emerging agricultural problem in sub-Saharan Africa. This has been documented primarily through cross-sectional studies, however detailed knowledge of the transmission dynamics of this disease in sub-Saharan Africa is lacking. This study aims to describe seasonal variations in sero-prevalence of antigen ELISA positive porcine cysticercosis in an endemic area. METHODS: A longitudinal study composed of three cross-sectional surveys was carried out in Mbeya Region, Tanzania; the first two six months apart (March/April 2012 and October/November 2012) and the last eight months later (July/August 2013). Venous blood was collected from pigs in 22 villages and analysed using Ag-ELISA. RESULTS: In each survey between 800–1000 serum samples were collected. The first survey revealed a cysticercosis sero-prevalence of 15% (n = 822, 95% CI: 13-18%). The sero-prevalence had significantly increased to 24% (p < 0.001, χ2-test, n = 812, 95% CI: 21-27%) at the time of the 6 month follow-up. At 14-months the sero-prevalence had dropped to 20% (p = 0.053, χ2-test, n = 998, 95% CI: 18-23%). Overall, this was a reduction in sero-prevalence compared with a study conducted in 2007 in the same area, where 31% (186/600) of pigs were found positive. CONCLUSION: Confined pigs did not have a lower sero-prevalence compared to free roaming pigs in any of the three surveys. Several factors may have contributed to the observed fluctuations such as African swine fever or seasonal variation in local crop production practices. Also, as the Ag-ELISA assay used is not species specific, variation in transmission of Taenia hydatigena could potentially influence the results. The observed fluctuations contradict a theoretical model which predicts a stable equilibrium, which only considers a two-compartment (pig and human) model excluding the effect of the environment. Whether the disease has an endemic equilibrium, or undergoes fluctuations dependent on extrinsic and/or socio-economic factors remains to be elucidated

Diagnosis and Interim Treatment Outcomes from the First Cohort of Multidrug-Resistant Tuberculosis Patients in Tanzania.

Kibong'oto National Tuberculosis Hospital (KNTH), Kilimanjaro, Tanzania. Characterize the diagnostic process and interim treatment outcomes from patients treated for multidrug-resistant tuberculosis (MDR-TB) in Tanzania. A retrospective cohort study was performed among all patients treated at KNTH for pulmonary MDR-TB between November 2009 and September 2011. Sixty-one culture-positive MDR-TB patients initiated therapy, 60 (98%) with a prior history of TB treatment. Forty-one (67%) were male and 9 (14%) were HIV infected with a mean CD4 count of 424 (±106) cells/µl. The median time from specimen collection to MDR-TB diagnosis and from diagnosis to initiation of MDR-TB treatment was 138 days (IQR 101-159) and 131 days (IQR 32-233), respectively. Following treatment initiation four (7%) patients died (all HIV negative), 3 (5%) defaulted, and the remaining 54 (89%) completed the intensive phase. Most adverse drug reactions were mild to moderate and did not require discontinuation of treatment. Median time to culture conversion was 2 months (IQR 1-3) and did not vary by HIV status. In 28 isolates available for additional second-line drug susceptibility testing, fluoroquinolone, aminoglycoside and para-aminosalicylic acid resistance was rare yet ethionamide resistance was present in 9 (32%). The majority of MDR-TB patients from this cohort had survived a prolonged referral process, had multiple episodes of prior TB treatment, but did not have advanced AIDS and converted to culture negative early while completing an intensive inpatient regimen without serious adverse event. Further study is required to determine the clinical impact of second-line drug susceptibility testing and the feasibility of alternatives to prolonged hospitalization

Smallholder Pig Marketing Systems in the Southern Highlands of Tanzania

A study using two cross-sectional and a longitudinal research designs was undertaken to assess smallholder pig marketing system to explore basic information for  improving smallholder pig production and marketing systems. The first design involved a cross-sectional survey of 300 pig farmers randomly selected in 30 villages in Mbozi and Mbeya rural districts. The second design used a cross-sectional survey of 124 pig traders randomly selected in 65 villages in Mbozi and Mbeya rural districts, and Mbeya Municipality. The third one used a longitudinal design and collected data from 40 pig farmers in 10 villages who had also participated in the first design. Results showed that, pig-marketing systems had various channels and segments moving mainly pigs and pork to farmers, traders and consumers.  Major market participants in the pig market chain were the pig farmers who played a dual role as pig producers and buyers, traders of live pigs and pork, and finally pork consumers. Most farmers (85%) bought pigs for breeding, while few (18%), bought for fattening. The mean (±SD) weight and age of pigs purchased was 18.2±12.6 kg and 6.2 ±4.7 months, respectively. Farmers sold about 70 and 30% of their pigs to pig traders and other farmers, respectively.  Pigs sold to farmers had significantly (P&lt; 0.001) lower mean age (6.1±1.5 months) and live weight (LW) (14.3± 3.6 kg) than pigs sold to traders with a mean age of 12.8± 1.5 months and LW of 40.0± 3.6kg. The study concludes that marketing systems were dominated by informal marketing channels, hence, limit the effectiveness of pig production and marketing. Marketed pigs had smaller weights compared to their ages, therefore contributing to poor returns to pig farmers and sub-optimal pork market supply. The study recommends strategic development of pig value chain for sustainable improvement of smallholder pig production and marketing systems and quality pork to consumers.

Taenia solium taeniosis and cysticercosis literature in Tanzania provides research evidence justification for control: A scoping review

Research evidence to guide policy and research agenda for Taenia solium taeniosis and cysticercosis (TSTC) in Sub-Saharan Africa is lacking. A scoping review of all TSTC studies undertaken in Tanzania and published up to November 2018 was conducted. The literature were searched from PUBMED, Tanzania Veterinary Journal, Tanzania Journal of Health Research and Google, and extracted to provide evidence on disease burden and potential for control. Fifty (50) articles met the inclusion criteria and were reviewed. Prevalence of taeniosis of 2.3% - 5.2% was estimated based on copro-antigen ELISA while human cysticercosis of &gt;16% was estimated based on serum antigen ELISA (Ag-ELISA) or IgG Western Blot. Neurocysticercosis contributed significantly to epilepsy in adults. Farm prevalence of porcine cysticercosis were 6.0% - 17.4% (lingual examination), 1.5% - 33.3% (Ag-ELISA) and incidence rates of 25/100 pig-years (lingual examination) and 69/100 pig-years (Ag-ELISA). Slaughter-slab prevalence were 0% - 18.2% (routine meat inspection). Lacking latrines, watering pigs with river or pond waters and feeding pigs with potato peels were associated with high porcine cysticercosis prevalence. Washing hands by dipping method instead of running water increased the risk of human cysticercosis. For the year 2012 the number of DALYs/1000 person-years for NCC-associated epilepsy was 0.7 (95% UI, 0.2–1.6), around 5 million USD (95% UI, 797,535– 16,933,477) were spent due to NCC-associated epilepsy and nearly 3 million USD (95% UI, 1,095,960–5,366,038) were potentially lost due to porcine cysticercosis. Three rounds of annual treatment of school-age children with praziquantel significantly reduced prevalence of taeniosis and porcine cysticercosis. A health education intervention reduced porcine cysticercosis incidence by approximately 43% with no improvement in pig confinement or use of latrines. A single dose of oxfendazole 30 mg/kg body weight eliminated T. solium cysticerci in pig musculature but not in the brain. High prevalence of T. solium infections in humans and pigs have been reported in Tanzania while the parasite accounts for a considerable proportion of epilepsy in humans that could be prevented. A one-health approach is mandatory to elimination of TSTC. There is potential for integrating control of TSTC with schistosomiasis control.
