Farming on the Fringes: Changes in Agriculture, Land Use and Livelihoods in Peri-Urban Dar es Salaam, Tanzania
Agriculture is a central part of Tanzania’s economy. Both within Dar es Salaam, its primate city, and in the city’s peri-urban zone, agriculture is an important part of the livelihood strategy for people of all social classes. However, because the peri-urban zone is one of transition from urban to rural, it tends to undergo more pronounced changes in land use over time than do the city and rural area it borders. This paper examines recent changes in agriculture, land use and livelihoods in the peri-urban zone of Dar es Salaam, Tanzania. Based on a literature review and semi-structured interviews conducted in three peri-urban villages, this paper argues that structural adjustment policies and changing land tenure regimes are impacting the presence and practice of agriculture in peri-urban Dar es Salaam. This paper further argues that because agriculture provides a means of investing in the future, it is an essential part of the livelihood strategy for middle and upper class residents of peri-urban areas

Importance of microbial culture collections for food safety research in climate change scenario
ICFC 2017 - International Conference on Food Contaminants (Book of Abstracts)Culture collections (CC) of microorganisms can play an important role in ensuring safe
food for the world's population. The preservation of different groups of microorganisms
such astoxigenic, pathogenic, phytopathogenic, deteriorating or biotechnological, allows
the development of research for their control or use. Then, it is important that these CC use
appropriate preservation techniques, species identification criteria rigid and a
multidisciplinary specialists group. The Microorganisms Culture Collection of the
Department of Food Science (CCDCA / UFLA) of the Federal University of Lavras (Minas
Gerais-Brazil) has been developing research projects that value and demonstrate the
importance of CC for food safety. Above all, among these researches, the most important
ones are:1) Use of essential oils of medicinal plants and condiments in the control of
toxigenic fungi; 2) Development of antiseptic with essential oils to control contaminating
microorganisms from the hands of food handlers;3) Monitoring of ochratoxigenic fungi in
fruits and beans coffee; 4) Fungi prevalent in regional artisanal cheeses in Brazil;5) Fungi
and yeasts of the terroir microbiota of tropical wines; 6) Evaluation of the expression of
genes involved in the synthesis of ochratoxin A as a function of the temperature changes in
coffee fruit processing. In projects 3) to 6), climate change certainly will influence food
safety. Therefore, CCs are important sources of research to ensure the preservation of
microbial biodiversity, and the development of research for production of safe food even in
the face of climate change different scenarios. The CCDCA / UFLA is accredited as a
Faithful Depositary is a member of the WFCC and registered in the WDCM with the
number 1081 and currently has more than 800 strains preserved at -80 ºC, belonging to
the genera Aspergillus, Cladosporium, Fusarium, Penicillium and Talaromyces.info:eu-repo/semantics/publishedVersio
A grander challenge: the case of how Makerere University College of Health Sciences (MakCHS) contributes to health outcomes in Africa
<p>Abstract</p> <p>Background</p> <p>“Grand challenges” in global health have focused on discovery and development of technologies to save lives. The “grander challenge” involves building institutions, systems, capacity and demand to effectively deliver strategies to improve health. In 2008, Makerere University began a radical institutional change to bring together four schools under one College of Health Sciences. This paper’s objective is to demonstrate how its leadership in training, research, and services can improve health in Uganda and internationally, which lies at the core of the College’s vision.</p> <p>Methods</p> <p>A comprehensive needs assessment involved five task forces that identified MakCHS’s contribution to the Ugandan government health priorities. Data were collected through analysis of key documents; systematic review of MakCHS publications and grants; surveys of patients, students and faculty; and key informant interviews of the College’s major stakeholders. Four pilot projects were conducted to demonstrate how the College can translate research into policy and practice, extend integrated outreach community-based education and service, and work with communities and key stakeholders to address their priority health problems.</p> <p>Results</p> <p>MakCHS inputs to the health sector include more than 600 health professionals graduating per year through 23 degree programs, many of whom assume leadership positions. MakCHS contributions to processes include strengthened approaches to engaging communities, standardized clinical care procedures, and evidence-informed policy development. Outputs include the largest number of outpatients and inpatient admissions in Uganda. From 2005-2009, MakCHS also produced 837 peer-reviewed research publications (67% in priority areas). Outcomes include an expanded knowledge pool, and contributions to coverage of health services and healthy behaviors. Impacts include discovery and applications of global significance, such as the use of nevirapine to prevent HIV transmission in childbirth and male circumcision for HIV prevention. Pilot projects have applied innovative demand and supply incentives to create a rapid increase in safe deliveries (3-fold increase after 3 months), and increased quality and use of HIV services with positive collateral improvements on non-HIV health services at community clinics.</p> <p>Conclusion</p> <p>MakCHS has made substantial contributions to improving health in Uganda, and shows great potential to enhance this in its new transformational role – a model for other Universities.</p
Characterization of the bacteriophage-derived endolysins PlySs2 and PlySs9 with in vitro lytic activity against bovine mastitis streptococcus uberis
Bovine mastitis, an infection of the cow’s mammary gland, is frequently caused by Streptococcus uberis and causes major economic losses in the dairy industry. The intramammary administration of antibiotics currently remains the predominant preventive and therapeutic measure. These antimicrobial compounds, ofwhich some are consideredcritical in human health care, are frequently applied as dry therapy resulting in their consistent overuse. Therefore, the use of antibiotics in the dairy sector is being questioned. We here identified two endolysins, i.e., PlySs2 and PlySs9, respectively derived from Streptococcus suis serotype-2 and -9 prophages, with lytic activity against S. uberis in an in vitro setting. Both endolysins gave clear lysis zones in spot-on-plate assays and caused a reduction of the optical density in a turbidity reduction assay. In depth characterization identified PlySs9 as the more potent endolysin over PlySs2 with a lower MIC value and about one additional log of killing. PlySs2 and PlySs9 were challenged to a panel of subclinical and clinical S. uberis milk isolates and were both able to lyse all strains tested. Molecular dissection of these endolysins in catalytic and cell wall binding subdomains resulted in major loss of killing and binding activity, respectively. Taken together, we here propose PlySs2 and PlySs9 as candidate compounds to the current antimicrobial arsenal known against bovine mastitis-causing S. uberis as future add-on or replacement strategy to the currently used intramammary antibiotics
Early antenatal prediction of gestational diabetes in obese women: development of prediction tools for targeted intervention
All obese women are categorised as being of equally high risk of gestational diabetes (GDM) whereas the majority do not develop the disorder. Lifestyle and pharmacological interventions in unselected obese pregnant women have been unsuccessful in preventing GDM. Our aim was to develop a prediction tool for early identification of obese women at high risk of GDM to facilitate targeted interventions in those most likely to benefit. Clinical and anthropometric data and non-fasting blood samples were obtained at 15+0–18+6 weeks’ gestation in 1303 obese pregnant women from UPBEAT, a randomised controlled trial of a behavioural intervention. Twenty one candidate biomarkers associated with insulin resistance, and a targeted nuclear magnetic resonance (NMR) metabolome were measured. Prediction models were constructed using stepwise logistic regression. Twenty six percent of women (n = 337) developed GDM (International Association of Diabetes and Pregnancy Study Groups criteria). A model based on clinical and anthropometric variables (age, previous GDM, family history of type 2 diabetes, systolic blood pressure, sum of skinfold thicknesses, waist:height and neck:thigh ratios) provided an area under the curve of 0.71 (95%CI 0.68–0.74). This increased to 0.77 (95%CI 0.73–0.80) with addition of candidate biomarkers (random glucose, haemoglobin A1c (HbA1c), fructosamine, adiponectin, sex hormone binding globulin, triglycerides), but was not improved by addition of NMR metabolites (0.77; 95%CI 0.74–0.81). Clinically translatable models for GDM prediction including readily measurable variables e.g. mid-arm circumference, age, systolic blood pressure, HbA1c and adiponectin are described. Using a ≥35% risk threshold, all models identified a group of high risk obese women of whom approximately 50% (positive predictive value) later developed GDM, with a negative predictive value of 80%. Tools for early pregnancy identification of obese women at risk of GDM are described which could enable targeted interventions for GDM prevention in women who will benefit the most
The StrongWomen Change Clubs: Engaging Residents to Catalyze Positive Change in Food and Physical Activity Environments
Introduction. The epidemic of obesity is a multifaceted public health issue. Positive policy and environmental changes are needed to support healthier eating and increased physical activity. Methods. StrongWomen Change Clubs (SWCCs) were developed through an academic-community research partnership between researchers at Cornell University and Tufts University and community partners (cooperative extension educators) in rural towns in seven U.S. states. Extension educators served as the local leader and each recruited 10–15 residents to undertake a project to improve some aspect of the nutrition or physical activity environment. Most residents had limited (or no) experience in civic engagement. At 6 and 12 months after implementation, the research team conducted key informant interviews with SWCC leaders to capture their perceptions of program process, benchmark achievement, and self-efficacy. Results. At 12 months, each SWCC had accomplished one benchmark; the majority had completed three or more benchmarks. They described common processes for achieving benchmarks such as building relationships and leveraging stakeholder partnerships. Barriers to benchmark achievement included busy schedules and resistance to and slow pace of change. Conclusion. Findings suggest that community change initiatives that involve stakeholders, build upon existing activities and organizational resources, and establish feasible timelines and goals can successfully catalyze environmental change
