RESUMEN
BACKGROUND: Child undernutrition is prevalent in Tanzania, and households rely primarily on local markets and home production as food sources. However, little is known about the contribution of food market purchases to nutrient intakes among children consuming complementary foods. OBJECTIVES: To quantify the relationships between diversity of foods purchased and produced by households and adequate child nutrient intake in Mara, Tanzania. METHODS: Cross-sectional baseline dietary and household food source data from the Engaging Fathers for Effective Child Nutrition and Development in Tanzania study were collected from mothers of 586 children aged 9-23 mo clustered in 80 villages in Mara, Tanzania. We conducted mixed effects linear regressions to quantify the association between the diversity of foods consumed at home, from market purchases and home production, and nutrient intake adequacy (based on 24-h food recalls). RESULTS: Children had inadequate diets, with fewer than half of children consuming adequate amounts of vitamin A, vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B9 (folate), calcium, iron, and zinc. Breastfeeding was associated with higher overall mean adequacy (b = 0.15-0.19 across models, P < 0.001). Diversity of foods purchased was positively associated with the intake of vitamin B12 and calcium (both P < 0.001); this effect was attenuated among breastfed children. Among nonbreastfed children, production diversity was positively associated with vitamin A intake (b=0.04; P < .05) but not with intake of other nutrients. CONCLUSIONS: Both household food purchase and food production diversities were positively associated with children's nutrient intake in rural Mara, Tanzania. Nutrition programming should consider the role of food markets in addition to home food production to improve child diets. This trial was registered at clinicaltrials.gov as NCT03759821, https://clinicaltrials.gov/study/NCT03759821.

Objectives: This study aimed to determine the magnitude of concurrent use of herbal medicines with ART, its associated factors and effect on viral load suppression and CD4 count among people living with HIV. Study design: This was a cross-sectional study involving 375 HIV positive patients on ART attending at care and treatment clinic (CTC). Methods: Data were obtained through face-to-face interviews using pre-structured questionnaires and patient's files through a checklist. Adherence was assessed though pill count method while CD4 count and viral load suppression were assessed using the Tanzania National guidelines for the management of HIV and AIDS. Data were analysed using STATA version 15. Independent predictors for herbal medicine use or viral suppression were assessed using univariate and multivariate logistic regression. Results: Out of 375 PLHIV, 37 (35%) reported to use herbal medicines concurrently with ART. Predictors for herbal medicines use were existence of chronic disease (OR = 4.53; CI = 1.87-10.95) (p = 0.001), male gender (OR = 0.57; CI = 0.35-0.93) (p = 0.02) and HIV clinical stage (OR = 1.71; CI = 0.99-2.94) (p = 005). PLHIV who used herbal medicines along with ART did not have a significantly higher chance of achieving viral suppression than PLHIV who did not use herbal medicines (OR = 1.42; CI = 0.71-2.82). There was no statistically significant difference on CD4 count (p = 0.8943) and viral load (p = 0.8612) between herbal medicines users and non-users. Conclusion: The utilization of herbal medicine among PLHIV on ART remains notably prevalent. Nonetheless, it is worth noting that despite the prevailing herbal medicine usage, there is no substantial effect on viral suppression. The primary determinants of the adoption of herbal medicines use were having chronic medical conditions and the stage of progression of the HIV infection.
RESUMEN
BACKGROUND: More than three-fourths of cervical cancer cases occur in low- and middle-income countries, with sub-Saharan Africa (SSA) accounting for approximately 25% of global mortality. The significant rise in the prevalence of cervical cancer in SSA amplifies the burden on caregivers, contributing to elevated rates of mental illness, particularly among spouses who provide care. Men who assume the role of caregivers for their partners with cervical cancer encounter unique challenges and substantial adjustments across multiple facets of life, impacting both their own quality of life and that of their partners. Despite this, there is a notable lack of extensive research on the experiences of male partners in caregiving roles, particularly within SSA countries like Tanzania. Therefore, this study aimed to explore the experiences of male partners providing care for women with cervical cancer in Dar es Salaam, Tanzania. METHODS: An exploratory qualitative study was undertaken to explore the experiences of 13 male partners, selected purposively and guided by the principle of saturation. Data gathering employed in-depth interviews utilizing a semistructured interview guide, with subsequent analysis conducted via a thematic analysis approach. RESULTS: Five themes and 13 subthemes were generated, encompassing psychosocial distress, attitudes towards cervical cancer, unity in the provision of care, economic burden, and altered sexual relationships. Participants reported experiencing emotional distress, shifts in social responsibilities, financial challenges, and unfulfilled sexual needs. Moreover, they expressed the need for social, psychological, financial, and sexual and reproductive support. CONCLUSION: This study underscores the numerous challenges encountered by male partners caring for women with cervical cancer, encompassing emotional distress, financial strain, and shifts in social and sexual dynamics. The identified themes and subthemes highlight the intricate interplay of these difficulties and stress the necessity for holistic support systems addressing the social, psychological, financial, and sexual aspects of male partners' experiences. The findings emphasize the importance of designing and implementing comprehensive support programmes tailored to the diverse needs of male partners, ultimately enhancing their quality of life and overall well-being. PATIENT OR PUBLIC CONTRIBUTION: Before the study, the nursing manager assisted in selecting three male partners randomly. These partners were involved in the design of the participants' information sheet, the evaluation of the interview schedule and rooms, and the dissemination of information about the study's purpose to the target population. Their valuable input contributed to improving the participant information sheet, refining data collection procedures and addressing ethical considerations. However, these individuals were not considered study participants. Throughout the study, in-charge nurses in the hospital were informed about the study's goals and helped organize appointments with participants and manage the interview schedule.

BACKGROUND: Vitamin B-12 status in human milk (HM) has critical implications for infant growth and development. Few studies have separately evaluated the effects of prenatal and postnatal maternal high-dose vitamin B-12 supplementation on HM vitamin B-12 concentration. OBJECTIVES: This randomized controlled trial aimed to assess the effects of prenatal and postnatal vitamin B-12 supplementation on HM vitamin B-12 at 6 wk and 7 mo postpartum. METHODS: Pregnant women were enrolled in Dar es Salaam, Tanzania, between 2001 and 2004. From recruitment (12-27 weeks of gestation) through 6 wk postpartum, participants were randomly assigned to daily oral multiple micronutrient supplementation or placebo. From 6 wk to 18 mo postpartum, a subset of participants was randomly assigned to a postnatal supplement or placebo. The supplement included 50 µg/d of vitamin B-12 and various other vitamins. HM vitamin B-12 concentrations were analyzed at 6 wk and 7 mo postpartum for 412 participants. RESULTS: The prevalence of HM vitamin B-12 of <310 pmol/L was 73.3% and 68.4% at 6 wk and 7 mo postpartum, respectively. Prenatal supplementation increased HM vitamin B-12 concentration (percent difference: 34.4; 95% CI: 17.0, 54.5; P < 0.001) at 6 wk; this effect was not present at 7 mo. Postnatal supplementation increased HM vitamin B-12 concentration (percent difference: 15.9; 95% CI: 1.91, 31.9; P = 0.025) at 7 mo. Effect modification between prenatal and postnatal supplementation on HM vitamin B-12 status at 7 mo was found, with the effects of prenatal and postnatal supplements more pronounced among those receiving control during the other period; the prenatal supplement had a greater effect with postnatal control, and the postnatal supplement had a greater effect with prenatal control. CONCLUSIONS: Prenatal maternal vitamin B-12 supplementation has benefits on short-term HM status, and postnatal maternal vitamin B-12 supplementation has benefits on long-term HM status. This trial was registered at clinicaltrials.gov as NCT00197548. https://clinicaltrials.gov/ct2/show/NCT00197548.

OBJECTIVE: Male engagement in pregnancy care can be beneficial for maternal and child health outcomes. In Tanzania, pregnant women are strongly encouraged to present to their first antenatal care (ANC) appointment with a male partner, where they jointly test for HIV. For some, this presents a barrier to ANC attendance. The objectives of this study were to identify factors associated with presenting to ANC with a male partner using a cross-sectional design and to assess whether women presenting without partners had significantly delayed presentation. METHODS: Pregnant women (n = 1007) attending a first ANC appointment in Moshi, Tanzania were surveyed. Questions captured sociodemographic characteristics and measures of psychosocial constructs. RESULTS: Just over half (54%) of women presented to care with a male partner. Women were more likely to present with a male partner if they were younger than 25 years old, married, Muslim, attending ANC for their first pregnancy, and testing for HIV for the first time. Women presenting to ANC with a male partner were significantly more likely to attend ANC earlier in their pregnancy than those presenting without male partners. CONCLUSION: Policy change allowing women to present to care with other supportive family members could promote earlier presentation to first ANC. Unmarried women may be at a disadvantage in presenting to ANC when policies mandate attendance with a male partner. Male partners of multiparous women should be encouraged to provide pregnancy support even after first pregnancies, and a wholistic emphasis (beyond HIV testing) on first ANC could encourage male engagement beyond the initial appointment.

BACKGROUND: Moderate acute malnutrition (MAM) affects over 30 million children aged < 5 years worldwide. MAM may confer a greater risk of developing severe malnutrition and even mortality in children. Assessing risk factors for MAM may allow for earlier recognition of children at risk of deleterious health outcomes. OBJECTIVE: To determine risk factors associated with the prevalence and development of MAM among children aged 6 to 59 months with acute diarrhoea who received treatment with oral rehydration solution and zinc supplementation. METHODS: We conducted a secondary analysis of data from a randomized, dose-finding trial of zinc among children with acute diarrhoea in India and Tanzania. We used regression models to assess risk factors for prevalent MAM at the start of diarrhoea treatment and to identify risk factors associated with the development of MAM at 60 days. MAM was defined as weight for length (or height) Z score ≤-2 and > -3 or mid-upper arm circumference < 12.5 and ≥ 11.5 cm. RESULTS: A total of 4,500 children were enrolled; 593 (13.2%) had MAM at the baseline. MAM at baseline was significantly less common among children in Tanzania than in India (adjusted risk ratio [aRR] 0.37, 95% confidence interval [CI]: 0.30, 0.44, P < 0.001), in children aged 24- < 60 months versus 6- < 12 months (aRR 0.46, 95% CI: 0.38, 0.56, P < 0.001), and in families with household wealth index higher than the median (aRR 0.79, 95% CI: 0.68, 0.92, P = 0.002). Sixty days after outpatient treatment and follow-up, 87 (2.5%) children developed MAM. When compared to children aged 6- < 12 months, children aged 24- < 60 months had a 52% lower risk of developing MAM. Every one unit increase in weight for length (or height) Z score at enrolment was associated with a 93% lower risk of developing MAM during follow-up. CONCLUSIONS: Among children with diarrhoea, younger children and those from households with lower wealth were at greater risk of MAM. These children may benefit from targeted interventions focusing on feeding (targeted nutrition support for at-risk households) and follow up in order to reduce the occurrence of MAM and its consequences.

PURPOSE: Reducing time between cancer screening, diagnosis, and initiation of treatment is best achieved when services are available in the same hospital. Yet, comprehensive cancer centers are typically unavailable in low- and middle-income countries (LMICs), where resources are limited and services scattered. This study explored the impact of establishing an in-house pathology laboratory at the largest public cancer hospital in Tanzania on the downstaging of cervical cancer. METHODS: We examined clinical datasets of 8,322 cervical cancer patients treated at the Ocean Road Cancer Institute (ORCI). The first period included patients treated from 2002 to 2016, before establishment of the pathology laboratory at ORCI; the second period (post-pathology establishment) included data from 2017 to 2020. Logistic regression analysis evaluated the impact of the pathology laboratory on stage of cervical cancer diagnosis. RESULTS: Patients treated during the post-pathology period were more likely to be clinically diagnosed at earlier disease stages compared to patients in the pre-pathology period (pre-pathology population diagnosed at early disease stage: 44.08%; post-pathology population diagnosed at early disease stage: 59.38%, p < 0.001). After adjustment for age, region of residence, and place of biopsy, regression results showed patients diagnosed during the post-pathology period had higher odds of early stage cervical cancer diagnosis than patients in the pre-pathology period (OR 1.35, 95% CI (1.16, 1.57), p < 0.001). CONCLUSIONS: Integrated and comprehensive cancer centers can overcome challenges in delivering expedited cervical cancer diagnosis and treatment. In-house pathology laboratories play an important role in facilitating timely diagnosis and rapid treatment of cervical and possibly other cancers in LMICs.

BACKGROUND: Provision of zinc supplementation to young children has been associated with reduced infectious morbidity and better growth outcomes. However, the metabolic pathways underlying these outcomes are unclear, and metabolomic data from humans undergoing zinc supplementation, particularly infants, are generally lacking. OBJECTIVES: This study aimed to examine the effect of zinc supplementation on metabolic profiles in Tanzanian infants aged 6 wk and 6 mo. METHODS: Blood samples were collected at age 6 wk and 6 mo from 50 Tanzanian infants who were enrolled in a randomized placebo-controlled trial of zinc supplementation (5 mg oral daily). Metabolomic analysis using an ultrahigh-performance liquid chromatography/tandem mass spectroscopy platform was performed to identify potential metabolomic profiles and biomarkers associated with zinc supplementation. Principal component analysis (PCA) was used to summarize metabolomic data from all samples. Two-way repeated measures analysis of variance with compound symmetry covariance structures were used to compare metabolome levels over time between infants in the 2 treatment arms. RESULTS: In PCA, the samples tended to be more separated by child age (6 wk compared with 6 mo) than by zinc supplementation status. We found that zinc supplementation affected a variety of metabolites associated with amino acid, lipid, nucleotide, and xenobiotic metabolism, including indoleacetate in the tryptophan metabolism pathway; 3-methoxytrosine and 4-hydrxoyphenylphruvate in the tyrosine pathway; eicosanedioate, 2-aminooctanoate, and N-acetyl-2-aminooctanoate in the fatty acid pathway; and N6-succinyladenosine in the purine metabolism pathway. Compared to the relatively small number of metabolites associated with zinc supplements, many infant metabolites changed significantly from age 6 wk to 6 mo. CONCLUSIONS: Zinc supplementation, despite having overall clinical benefits, appears to induce limited metabolomic changes in blood metabolites in young infants. Future larger studies may be warranted to further examine metabolic pathways associated with zinc supplementation. The parent trial was registered at clinicaltrials.gov as NCT00421668.

Tanzania developed its 2016-26 health financing strategy to address existing inequities and inefficiencies in its health financing architecture. The strategy suggested the introduction of mandatory national health insurance, which requires long-term legal, interministerial and parliamentary procedures. In 2017/18, improved Community Health Fund (iCHF) was introduced to make short-term improvements in coverage and financial risk protection for the informal sector. Improvements involved purchaser-provider split, portability of services, uniformity in premium and risk pooling at the regional level. Using qualitative methods and drawing on the policy analysis triangle framework (context, content, actors and process) and criteria for procedural fairness, we examined the decision-making process around iCHF and the extent to which it met the criteria for a fair process. Data collection involved a document review and key informant interviews (n = 12). The iCHF reform was exempt from following the mandatory legislative procedures, including processes for involving the public, for policy reforms in Tanzania. The Ministry of Health, leading the process, formed a technical taskforce to review evidence, draw lessons from pilots and develop plans for implementing iCHF. The taskforce included representatives from ministries, civil society organizations and CHF implementing partners with experience in running iCHF pilots. However, beneficiaries and providers were not included in these processes. iCHF was largely informed by the evidence from pilots and literature, but the evidence to reduce administrative cost by changing the oversight role to the National Health Insurance Fund was not taken into account. Moreover, the iCHF process lacked transparency beyond its key stakeholders. The iCHF reform provided a partial solution to fragmentation in the health financing system in Tanzania by expanding the pool from the district to regional level. However, its decision-making process underscores the significance of giving greater consideration to procedural fairness in reforms guided by technical institutions, which can enhance responsiveness, legitimacy and implementation.

BACKGROUND: The popular use of herbal medicines necessitates national regulatory authorities to have efficient mechanisms for the control of these products including marketing authorization (MA) and safety follow-up. Herbal medicines like conventional medicines require assessment of efficacy, safety and quality information before MA can be granted. However, the complete proof of safety is mainly based on the history of the long-term traditional use. Herbal medicines can cause adverse reactions due to various factors and thus require clinical trials to ensure their safety. Herbal medicines treatment practices involve combinations of different plants to achieve the desired effect while multiple herbal components have been known to cause herbal-herbal toxicity and interactions due to variety of complex active ingredients in plants. Compliance with regulatory requirements on herbal medicines has been shown to be difficult for manufacturers since different countries have different regulatory requirements with wide variations which results in the MA of very few herbal medicines. Limited studies on dossiers of marketing authorization of herbal medicines have been performed in other countries, with no studies in African regulatory system settings. The aim of this study is to determine the type of safety documentation that is submitted on herbal medicines application dossiers to support MA in Tanzania. METHODS: A cross-sectional retrospective study of herbal medicines dossiers submitted at the Tanzania Medicines and Medical Devices Authority from 2009 to 2020 was conducted. RESULTS: As many as 75% of the herbal products applications were combination products made by more than one herbal substance or plant. Out of 84 dossiers subjected to analysis the majority did not provide evidence of preclinical (55%) and clinical safety data (68%). Evidence of safety data in humans was mostly from the literature (70%) and not manufacturers' clinical studies. Quality parameters with safety implications were not included in 48% and 23% of the active herbal substance and finished product specifications, respectively. CONCLUSION: Analysis of the herbal medicine dossiers submitted showed major deficiencies of safety data to support MA. Manufactures need to provide evidence to support the safety of their products for evidence-based regulatory decisions and to avoid multiple reviews of the applications.
RESUMEN
BACKGROUND: Right through history, humans have relied heavily on plants for sustenance and the healing of different ailments. One of the long-standing traditions that communities have inherited from earlier generations is the use of herbal medicines for the treatment of paediatric ailments, including diarrhoea. This study showcased medicinal plants used by traditional healers for the treatment of diarrhoeal diseases among under-five children in North-eastern Tanzania. METHODS AND DESIGN: A qualitative research approach and a narrative research design were employed. The research was carried out in the districts of Korogwe and Handeni in North-eastern Tanzania, with 52 in-depth interviews performed with participants (traditional healers). Purposive sampling method was used to select participants, and a thematic analysis framework was used to analyze the data. RESULTS: Study results indicate that traditional healers had enormous insights and were well informed about medicinal plants that were perceived to be efficacious in treating diarrhoeal diseases among under-five children. A total of 54 medicinal plants were reported by the participants to be effective in healing diarrhoeal diseases among under-five children. However, out of 54 medicinal plants, 15 were predominantly disclosed by the majority of participants. Those medicinal plants include Psidium guajava, Rhus natalensis, Ozoroa insignis, Tamarindus indica, Ocimum suave, Combretum molle, Zanha africana, Solanum incanum, and Ximenia americana. Other medicinal plants mentioned by most participants include, Ochna holstii, Elaeodendron schlechterianum, Albizia anthelmintica, Commiphora pteleifolia, Salacia stuhlmanniana, and Zenkerella grotei. CONCLUSION: All traditional healers seemed to have a clear understanding regarding the medicinal plants that were used to treat diarrhoeal diseases among under-five children. The participants acknowledged to treating under-five children with diarrhoeal diseases using herbal medications on multiple occasions. The findings of this study should inspire more in-depth botanical research to determine whether the medicinal plants reported in this study have anti-diarrhoeal properties.

BACKGROUND: Women who experience antenatal depression may be at increased risk of adverse birth outcomes. Few studies have examined this association among women living with HIV (WHIV). METHODS: We conducted a prospective cohort study of 2298 pregnant WHIV on antiretroviral therapy (ART) in Dar es Salaam, Tanzania, who were participants in a randomized trial of vitamin D3 supplementation. Depressive symptoms were assessed at 12-27 weeks gestation using the Hopkins Symptoms Checklist (HSCL-25). Generalized estimating equations to account for twins were used to assess the relative risks of adverse birth outcomes. RESULTS: Approximately 67 % of the women in our study population reported symptoms consistent with depression. We observed a 4.0 % prevalence of stillbirth and a 25.1 % prevalence of preterm birth. We found that low social support, higher education, and more recent initiation of ART were associated with a greater risk of antenatal depression. There was no association of antenatal depression with risk of fetal loss, stillbirth, low birth weight, birth weight, preterm birth, gestational age at delivery, or small-for-gestational age. LIMITATIONS: Depression was self-reported and only collected at one timepoint in pregnancy. Our findings may not be generalizable to all WHIV. CONCLUSIONS: Our findings illustrate the high risk of both depression and adverse birth outcomes among WHIV and underscore the need for interventions to improve their mental health and the health of their infants; however, the relationship between depression and birth outcomes remains unclear. Further research on this topic is merited, particularly examining the chronicity and timing of depression in pregnancy.

Over the last 2 decades, the introduction of targeted therapies and the advances in the detection of BCR::ABL1 oncogene have dramatically improved comprehensive care for patients with Chronic myeloid leukemia (CML). The once deadly malignancy has now transformed into a chronic disease with an overall patient survival approaching that of the age-matched general population. While excellent prognoses have been reported among CML patients in high-income countries, it is unfortunately not the same for those living in low and middle-income (LMIC) countries such as Tanzania. This disparity is largely contributed by barriers associated with the provision of comprehensive care including early diagnosis, access to treatment, and regular monitoring of the disease. In this review, we will share our experiences and lessons learned in setting up a network of comprehensive care for patients with CML in Tanzania.

Key Clinical Message: Rare cancer originating from parathyroid parenchymal cells. Preoperative diagnosis is often difficult. Presents with normal serum levels of calcium and parathyroid hormone. Treated by en bloc resection. Benefits of adjuvant therapy are unclear. Abstract: Parathyroid carcinoma is an uncommon endocrine tumor. Its typical presentation is that of primary hyperparathyroidism with elevated serum calcium and parathormone levels. Nonfunctioning carcinoma of the parathyroid gland with normal serum calcium levels is extremely rare. This paper describes a case of nonfunctioning parathyroid carcinoma and brief literature review thereof.
RESUMEN
BACKGROUND: Cardiovascular diseases (CVDs) have become an important cause of ill health and death among people living with HIV and/or AIDS (PLHIV) in the antiretroviral therapy (ART) era. There is scarce data on the burden of hypertension (HTN) and risk factors for CVDs among PLHIV in developing countries, including Tanzania during the ART era. OBJECTIVE(S): To determine the prevalence of HTN and risk factors for CVDs among ART naïve PLHIV initiating ART. METHODS: We analysed baseline data of 430 clinical trial participants on the effect of low-dose aspirin on HIV disease progression among HIV-infected individuals initiating ART. HTN was the outcome CVD. Traditional risk factors for CVDs studied were age, alcohol consumption, cigarette smoking, individual and family history of CVDs, diabetes mellitus (DM), obesity/overweight, and dyslipidaemia. A generalized linear model (robust Poisson regression) was used to determine the predictors for HTN. RESULTS: The median (IQR) age was 37 (28, 45) years. Females were the majority contributing 64.9% of all participants. The prevalence of HTN was 24.8%. The most prevalent risk factors for CVDs were dyslipidaemia (88.3%), alcohol consumption (49.3%), and overweight or obesity (29.1%). Being overweight or obese predicted the occurrence of HTN, aPR 1.60 (95% CI 1.16-2.21) while WHO HIV clinical stage 3 was protective against HTN, aPR 0.42(95% CI 0.18-0.97). CONCLUSION: The prevalence of HTN and traditional risk factors for CVDs in the treatment naïve PLHIV initiating ART are significant. Identifying these risk factors and managing them at the time of ART initiation may lower future CVDs among PLHIV.

OBJECTIVE: To evaluate the effectiveness of a nutrition education package on feeding practices, nutrient intakes and growth of infants in rural Tanzania. DESIGN: Cluster-randomized controlled trial in 18 villages allocated to nutrition education package (n = 9) or routine health education (n = 9 villages), measured at baseline (6 months) and end of the trial (12 months). SETTING: Mpwapwa district. PARTICIPANTS: Infants aged 6-12 months and their mothers. INTERVENTION(S): Six months of nutrition education package (group education, counseling, cooking demonstrations) and regular home visits by village health workers. MAIN OUTCOME MEASURE(S): Primary outcome measure was the mean change in length-for-age z-scores. Secondary outcomes included mean changes in weight-for-length z-scores (WLZ), intakes of energy, fat, iron and zinc, the proportion of children consuming foods from ≥ 4 food groups (ie, dietary diversity) and consuming the recommended number of semisolid/soft meals and snacks per day (ie, meal frequency). ANALYSIS: Multilevel mixed-effects regression models. RESULTS: Mean change in length-for-age z-scores (ß = 0.20, P = 0.02), energy (in kcal) (ß = 43.8, P = 0.02), and fat (in grams) (ß =2.7, P = 0.03) intakes were significant in the intervention but not in the control group. There was no effect on iron and zinc intakes. More infants in the intervention than the control group consumed meals from ≥ 4 food groups (71.8% vs 45.3%, P = 0.002). The mean increase in meal frequency (ß = 0.29, P = 0.02) and dietary diversity (ß = 0.40, P = 0.01) were more significant in the intervention than control. CONCLUSIONS AND IMPLICATIONS: The nutrition education package is feasible and can be implemented with high coverage, demonstrating the potential to improve feeding practices, nutrient intake and growth in rural Tanzania.

INTRODUCTION: In Low- and Middle-Income Countries (LMICs), maternal and infant mortality remains a significant problem. Inadequate healthcare provider competencies, including those of midwives, are cited as one of the major contributors to the high maternal and newborn mortality rates. Thus, enhancing the skills of midwives is a prerequisite for enhancing positive maternal and newborn health outcomes. This study describes the lessons learned from a Midwifery Emergencies Skills Training (MEST) project implemented in Tanzania between 2013 and 2018. METHODS: An exploratory qualitative study was used to purposefully recruit and interview twelve health facility in-charges and eighteen midwives from twelve selected health facilities in six districts of Tanzania mainland to discover their perceptions about the midwifery practice after MEST training. The data were transcribed verbatim and analysed with qualitative content analysis. RESULTS: Four categories were generated from the analysis (i) enhanced knowledge and skills in the provision of midwifery care and management of obstetric emergencies, (ii) improved midwives' communication skills, (iii) increased trust and support between midwives and community and (iv) transformed attitudes of midwives toward continued professional development (CPD). CONCLUSION: MEST enhanced the knowledge and skills of midwives in the management of obstetric emergencies and referral protocol practice. However, notable gaps remain in the capacity of midwives to provide human rights-based respectful maternity care. Continued professional development for nurses and midwives through training, mentorship and supervision programs is recommended for improving maternal and newborn health.

Introduction: We are in an era of rapid technological advance and digitalization. Countries around the world want to leverage technology to improve health outcomes by accelerating data use and increasing evidence-based decision-making to inform action in the health sector. Yet, there is no "one size fits all" approach to achieving this. To understand more, PATH and Cooper/Smith conducted a study documenting and analyzing the experiences of five African countries (Burkina Faso, Ethiopia, Malawi, South Africa, and Tanzania) that are on this digitalization journey. The goal was to examine their different approaches and develop a holistic model of digital transformation for data use that identifies what the essential components for digitalization success are and how they interact with each other. Methods: Our research had two phases: first, we analyzed documentation from the five countries to identify core components and enabling factors for successful digital transformation, as well as barriers encountered; and second, we held interviews with key informants and focus groups within the countries to fill gaps and validate findings. Findings: Our findings show that the core components of digital transformation success are highly interrelated. We found that the more successful digitalization efforts address issues that cut across components-such as stakeholder engagement, health workforce capacity, and governance structures-and consider more than just systems and tools. Specifically, we found two critical components of digital transformation that have not been addressed in previous models like the eHealth strategy building blocks developed by the World Health Organization and the International Telecommunication Union: (a) cultivating a culture of data use throughout the health sector and (b) managing the process of system-wide behavior change required to move from manual or paper-based to digital systems. Conclusion: The resulting model is based on the study's findings and is intended to inform low- and middle-income (LMIC) country governments, global policymakers (such as WHO), implementers, and funders. It provides specific, concrete, evidence-based strategies these key stakeholders can implement to improve digital transformation for data use in health systems, planning, and service delivery.

INTRODUCTION: Tanzania aimed to reduce micronutrient deficiencies and neural tube defects by introducing mandatory fortification of large-scale packaged wheat and maize flour but not for small- and medium-scale mills. OBJECTIVES: Ascertain the proportion of the population in Morogoro region, Tanzania, that consumes packaged maize flour from small-, medium- and large-mills; and understand the impact of monthly apparent purchase and consumption of packaged flour. METHODS: In 2018, a regional, multistage cluster probability study was conducted among residents in Morogoro region living in households that reported consuming maize flour. Interviews collected information on sociodemographic factors and patterns of household flour consumption. Weighted medians estimated daily apparent flour consumption and the estimated average requirement (EAR), according to age. RESULTS: Information was collected on 711 households. Packaged maize flour was purchased 10-12 months of the year by 22.9% of households, 6-9 months by 17.6% of households, 1-5 months by 25.1% of households, and 34.4% did not purchased maize flour. Median apparent daily consumption of maize flour was 209.7 g/d/adult male equivalent (AME). Apparent median daily consumption of maize flour was 230.1 g/d/AME in rural areas and 176.2 g/d/AME in urban areas; 228.7 g/d/AME among males and 196.4 g/d/AME among females. If all packaged maize flour were fortified according to standards, those consuming packaged maize flour 10-12 months of the year would apparently consume 199.9 µg folic acid/d representing 49.7% of daily EAR requirements. CONCLUSIONS: Fortifying packaged maize flour at small-, medium- and large-mills is a promising strategy for increasing access to micronutrients, including folic acid.

Since the mineral, phosphorus (P), has dual properties of being limited resources for use, and being a pollutant for studying sustainable management of anthropogenic P flows in wetlands and soils, currently P receives the highest interests among researchers around the world. This study has successfully mapped P flows for a reference year (2017) and a future year (2030) using different scenarios of food production and consumption system (hereafter 'system') in the Mwanza region (Tanzania). The results showed that the total P input and output for 2017 alone were 9770 t and 7989 t, respectively. However, as high as 1781 tP accumulated in the system and the potentially recyclable P found, is yet to be recovered due to economic reasons and the lack of market. The main anthropogenic P input to the system occurred via imported feed, fertilizer, and crop food, accounting for about 99.72 % of the total input flow. The output was comprised of animal products exported with 3428 tP, and various P-contained wastes which were lost to water bodies with 4561tP. Analysis of the 2030 scenario showed that setting P management objectives from different perspectives such as the total P budget balance, potential recyclable P, and P emission, can help develop differentially preferred management strategies and measures in the Mwanza region. The combination of diet change, precision feeding, and integrated waste management practices presents the best prospects for decreasing P budget and losses, and the amount of P that can be potentially recovered from the system. We propose a package of integrated P management measures for the Mwanza region. Given the similarity of regional socio-economic development background around the Lake Victoria basin, the model can be used to guide the study of anthropogenic P flow analysis in other areas along the shore of Lake Victoria (Africa).
