Kansa talk: mapping cancer terminologies in Bagamoyo, Tanzania towards dignity-based practice.

This paper reports and examines the results of qualitative research on the use of local cancer terminology in urban Bagamoyo, Tanzania. Following recent calls to unify evidence and dignity-based practices in global health, this research locates local medical sociolinguistics as a key place of entry into creating epistemologically autonomous public health practices. We used semistructured ethnographic interviews to reveal both the contextual and broader patterns related to use of local cancer terminologies among residents of Dunda Ward in urban Bagamoyo. Our findings suggest that people in Bagamoyo employ diverse terms to describe and make meanings about cancer that do not neatly fit with biomedical paradigms. This research not only opens further investigation about how ordinary people speak and make sense of the emerging cancer epidemic in places like Tanzania, but also is a window into otherwise conceptualisations of 'intervention' onto people in formerly colonised regions to improve a health situation. We argue that adapting biomedical concepts into local sociolinguistic and knowledge structures is an essential task in creating dignity-based, evidence-informed practices in global health.

[Principaux facteurs expliquant l'hésitation vaccinale contre la Covid-19 en Tanzanie]. / Key Drivers of Low Covid-19 Vaccine Uptake in Tanzania.

WHO defines vaccine hesitancy as delay in acceptance or refusal of vaccines despite the availability of vaccine services. It is a complex phenomenon that varies through time, place and vaccines. In this comment, we highlight the context-specific variation of Covid-19 vaccine hesitancy in Tanzania. We suggest Covid-19 hesitancy in Tanzania is influenced with high burden of infectious disease, poor testing capabilities and demographic characteristics.

"I let others speak about condoms:" Muslim religious leaders' selective engagement with an NGO-Led family planning project in rural Tanzania.

In the past two decades, religious leaders have garnered increased interest from health ministries and NGOs as promoters, educators, and implementers of sensitive health programs such as family planning in several African countries. While religious leaders' role as public health actors has been well-documented, there are few ethnographic accounts of how religious leaders engage with public health programs, especially family planning. Informed by twelve months of ethnographic study in three rural and peri-urban locations in Kilombero district in 2014-2016, this article examines how Muslim religious leaders experienced and negotiated their role as implementers of family planning services. Governments and NGOs seek religious leaders' social capital to increase community's knowledge of and demand for family planning as well as to diffuse the community's moral anxieties surrounding its use. Participant observation and interviews, however, show that religious leaders selectively engage with family planning projects, balancing project demands, their own interests and the existing norms and perceptions in the community. Religious leaders stood beside other team members promoting condoms, but they remained silent themselves on condom promotion selecting instead to speak on the dangers of teenage pregnancy. Tensions, power differentials and a mélange of interests, existing and emergent, set the stage for religious leaders to selectively engage with the family planning project. Selective engagement was beneficial for both parties. Religious leaders received training on modern family planning, gained symbolic capital by associating with a powerful NGO, and expanded their social networks while government officials and NGOs received indirect support for family planning programs.

Batch-produced, GIS-informed range maps for birds based on provenanced, crowd-sourced data inform conservation assessments.

Accurate maps of species ranges are essential to inform conservation, but time-consuming to produce and update. Given the pace of change of knowledge about species distributions and shifts in ranges under climate change and land use, a need exists for timely mapping approaches that enable batch processing employing widely available data. We develop a systematic approach of batch-processing range maps and derived Area of Habitat maps for terrestrial bird species with published ranges below 125,000 km2 in Central and South America. (Area of Habitat is the habitat available to a species within its range.) We combine existing range maps with the rapidly expanding crowd-sourced eBird data of presences and absences from frequently surveyed locations, plus readily accessible, high resolution satellite data on forest cover and elevation to map the Area of Habitat available to each species. Users can interrogate the maps produced to see details of the observations that contributed to the ranges. Previous estimates of Areas of Habitat were constrained within the published ranges and thus were, by definition, smaller-typically about 30%. This reflects how little habitat within suitable elevation ranges exists within the published ranges. Our results show that on average, Areas of Habitat are 12% larger than published ranges, reflecting the often-considerable extent that eBird records expand the known distributions of species. Interestingly, there are substantial differences between threatened and non-threatened species. Some 40% of Critically Endangered, 43% of Endangered, and 55% of Vulnerable species have Areas of Habitat larger than their published ranges, compared with 31% for Near Threatened and Least Concern species. The important finding for conservation is that threatened species are generally more widespread than previously estimated.

Who are CHWs? An ethnographic study of the multiple identities of community health workers in three rural Districts in Tanzania.

BACKGROUND: Numerous studies have examined the role of community health workers (CHWs) in improving the delivery of health services and accelerating progress towards national and international development goals. A limited but growing body of studies have also explored the interactions between CHWs' personal, communal and professional identities and the implications of these for their profession. CHWs possess multiple, overlapping roles and identities, which makes them effective primary health care providers when properly supported with adequate resources, but it also limits their ability to implement interventions that only target certain members of their community, follow standard business working days and hours. In some situations, it even prevents them from performing certain duties when it comes to sensitive topics such as family planning. METHODS: To understand the multiple identities of CHWs, a mixture of qualitative and ethnographic methods was utilized, such as participant observation, open-ended and semi-structured interviews, and focus group discussions with CHWs, their supervisors, and their clients. The observation period began in October 2013 and ended in June 2014. This study was based on implementation research conducted by the Connect Project in Rufiji, Ulanga and Kilombero Districts in Tanzania and aimed to understand the role of CHWs in the provision of maternal and child health services in rural areas. RESULTS: To our knowledge, this was the first study that employed an ethnographic approach to examine the relationship between personal, communal and professional identities, and its implications for CHWs' work in Tanzania. Our findings suggest that it is difficult to distinguish between personal and professional identities among CHWs in rural areas. Important aspects of CHW services such as personalization, access, and equity of health services were influenced by CHWs' position as local agents. However, the study also found that their personal identity sometimes inhibited CHWs in speaking about issues related to family planning and sexual health. Being local, CHWs were viewed according to the social norms of the area that consider the gender and age of each worker, which tended to constrain their work in family planning and other areas. Furthermore, the communities welcomed and valued CHWs when they had curative medicines; however, when medical stocks were delayed, the community viewed the CHWs with suspicion and disinterest. Community members who received curative services from CHWs also tended to become more receptive to their preventative health care work. CONCLUSION: Although CHWs' multiple roles constrained certain aspects of their work in line with prevalent social norms, overall, the multiple roles they fulfilled had a positive effect by keeping CHWs embedded in their community and earned them trust from community members, which enhanced their ability to provide personalized, equitable and relevant services. However, CHWs needed a support system that included functional supply chains, supervision, and community support to help them retain their role as health care providers and enabled them to provide curative, preventative, and referral services.

Prevalence and assessment of malnutrition among children attending the Reproductive and Child Health clinic at Bagamoyo District Hospital, Tanzania.

BACKGROUND: Malnutrition has long been associated with poverty, poor diet and inadequate access to health care, and it remains a key global health issue that both stems from and contributes to ill-health, with 50 % of childhood deaths due to underlying undernutrition. The purpose of this study was to determine the prevalence of malnutrition among children under-five seen at Bagamoyo District Hospital (BDH) and three rural health facilities ranging between 25 and 55 km from Bagamoyo: Kiwangwa, Fukayosi, and Yombo. METHODS: A total of 63,237 children under-five presenting to Bagamoyo District Hospital and the three rural health facilities participated in the study. Anthropometric measures of age, height/length and weight and measurements of mid-upper arm circumference were obtained and compared with reference anthropometric indices to assess nutritional status for patients presenting to the hospital and health facilities. RESULTS: Overall proportion of stunting, underweight and wasting was 8.37, 5.74 and 1.41 % respectively. Boys were significantly more stunted, under weight and wasted than girls (p-value < 0.05). Children aged 24-59 months were more underweight than 6-23 months (p-value = <0.0001). But, there was no statistical significance difference between the age groups for stunting and wasting. Children from rural areas experienced increased rates of stunting, underweight and wasting than children in urban areas (p-value < 0.05). The results of this study concur with other studies that malnutrition remains a problem within Tanzania; however our data suggests that the population presenting to BDH and rural health facilities presented with decreased rates of malnutrition compared to the general population. CONCLUSIONS: Hospital and facility attending populations of under-five children in and around Bagamoyo suffer moderately high rates of malnutrition. Current nutrition programs focus on education for at risk children and referral to regional hospitals for malnourished children. Even though the general population has even greater malnutrition than the population presenting at the hospital, in areas of high malnutrition, hospital-based interventions should also be considered as centralized locations for reaching thousands of malnourished children under-five.

Toward quantification of the impact of 21st-century deforestation on the extinction risk of terrestrial vertebrates.

Conservation actions need to be prioritized, often taking into account species' extinction risk. The International Union for Conservation of Nature (IUCN) Red List provides an accepted, objective framework for the assessment of extinction risk. Assessments based on data collected in the field are the best option, but the field data to base these on are often limited. Information collected through remote sensing can be used in place of field data to inform assessments. Forests are perhaps the best-studied land-cover type for use of remote-sensing data. Using an open-access 30-m resolution map of tree cover and its change between 2000 and 2012, we assessed the extent of forest cover and loss within the distributions of 11,186 forest-dependent amphibians, birds, and mammals worldwide. For 16 species, forest loss resulted in an elevated extinction risk under red-list criterion A, owing to inferred rapid population declines. This number increased to 23 when data-deficient species (i.e., those with insufficient information for evaluation) were included. Under red-list criterion B2, 484 species (855 when data-deficient species were included) were considered at elevated extinction risk, owing to restricted areas of occupancy resulting from little forest cover remaining within their ranges. The proportion of species of conservation concern would increase by 32.8% for amphibians, 15.1% for birds, and 24.7% for mammals if our suggested uplistings are accepted. Central America, the Northern Andes, Madagascar, the Eastern Arc forests in Africa, and the islands of Southeast Asia are hotspots for these species. Our results illustrate the utility of satellite imagery for global extinction-risk assessment and measurement of progress toward international environmental agreement targets.

Mating behaviour in Lymnaea stagnalis pond snails is a maternally inherited, lateralized trait.

Lateralization of the brain has traditionally been considered a specialization that is confined to the vertebrates, but recent studies have revealed that a range of invertebrates also have a brain that is structurally asymmetric and/or each side performs a different set of functions. Here, we show that the precopulatory mating behaviour of the pond snail Lymnaea stagnalis is lateralized. We present evidence that the asymmetry of the behaviour corresponds to the sinistral or dextral shell coil, or chirality, of the snail, and is apparently also controlled by a maternal effect locus. As sinistral snails also tend to have mirror image brains, these findings suggest that the lateralized sexual behaviour of L. stagnalis is set up early in development, and is a direct consequence of the asymmetry of the entire body.
