Tourism Potential & Challenges for Islamic Monastery Heritage Sites in Ethiopia: Tiru Sina Mosque
The main intent of this study is to investigate unusual Islamic monastery heritage sites by focusing on the potential resources and challenges for religious tourism development at Tiru Sina Mosque. To meet this objective a qualitative approach was utilised and data were collected through interviews with elderly religious fathers in addition to culture and tourism officers. Additional focus groups, discussions and deep personal observations were conducted. As the findings reveal, Tiru Sina Mosque is a unique Islamic monastic site with great potential for religious tourism development. This unique Islamic monastery heritage site has socio-cultural, economic, historical, religious and aesthetic values. The study also confirmed, even though the area is rich in cultural heritage, there are serious challenges that affect its development. The major problems are lack of awareness, poor handling systems for heritage, lack of infrastructural development, absence of coordination among stakeholders, shortage of skilled professionals, lack of cooperation and partnership among different stakeholders, heritage destruction and lack of conservation, and lack of risk management

Evaluation of the airflow characteristics, cooling kinetics and quality keeping performances of various internal plastic liners in pomegranate fruit packaging
CITATION: Lufu, R. et al. 2020. Evaluation of the airflow characteristics, cooling kinetics and quality keeping performances of various internal plastic liners in pomegranate fruit packaging. Food Packaging and Shelf Life, 26. doi:10.1016/j.fpsl.2020.100585.The original publication is available at https://www.sciencedirect.com/journal/food-packaging-and-shelf-lifeThere is a trade-off to be optimised carefully as plastic liners deal with postharvest cooling processes as well as the produce quality and sustainability requirements. Understanding the implementation of plastic liners in the fresh fruit cold chain is required to reconcile the opposing roles. In this paper, the performances of four types of internal packaging plastic liners were studied. The airflow characteristics, cooling rate, cooling uniformity and quality keeping performances were measured. Cases: no liner, non-perforated liner, micro-perforated liner, macro perforated liner with 2 mm diameter holes, macro perforated liner 4 mm diameter holes were investigated. Generally, the liners delayed the cooling rate significantly. Non-perforated and micro-perforated liners are similar in terms of airflow resistance and cooling rate, both delayed the optimum cooling time by 5 h compared to the plastic-free case. On the other hand, macro-perforated liners cause a delay of only 3 h.https://www.sciencedirect.com/science/article/pii/S2214289420306037Publishers versio
"Death is a better option than being treated like this" : a prevalence survey and qualitative study of depression among multi-drug resistant tuberculosis in-patients
BACKGROUND: Understanding of the relationship between multi-drug resistant tuberculosis and mental health is limited. With growing prevalence of multi-drug resistant tuberculosis, addressing mental ill-health has potential to improve treatment outcomes and well-being. In several low and middle-income contexts hospitalisation during treatment is common. Understanding of the impact on mental ill-health are required to inform interventions for patients with multi-drug resistant tuberculosis. Our aim was to identify the prevalence of comorbid depression among in-patients being treated for multi-drug resistant tuberculosis and to explore their experiences of comorbid disease and the care they received in a large specialist chest hospital in Dhaka, Bangladesh. METHODS: We conducted a quantitative cross-sectional survey among 150 multi-drug resistant tuberculosis in-patients (new cases = 34%, previously treated = 66%) in 2018. A psychiatrist assessed depression was assessed with the Structured Clinical Interview for Depression (SCID DSM-IV). We used multi-level modelling to identify associations with depression. Experience Bangladeshi researchers conducted qualitative interviews with 8 patients, 4 carers, 4 health professionals and reflective notes recorded. Qualitative data was analysed thematically. RESULTS: We found 33.8% (95% CI 26.7%; 41.7%) of patients were depressed. While more women were depressed 39.3% (95% CI 27.6%; 52.4%) than men 30.4% (95% CI 22%; 40.5%) this was not significant. After controlling for key variables only having one or more co-morbidity (adjusted odds ratio [AOR] = 2.88 [95% CI 1.13; 7.33]) and being a new rather than previously treated case (AOR = 2.33 [95% CI 1.06; 5.14]) were associated (positively) with depression. Qualitative data highlighted the isolation and despair felt by patients who described a service predominantly focused on providing medicines. Individual, familial, societal and health-care factors influenced resilience, nuanced by gender, socio-economic status and home location. CONCLUSIONS: Patients with multi-drug resistant tuberculosis are at high risk of depression, particularly those with co- and multi-morbidities. Screening for depression and psycho-social support should be integrated within routine TB services and provided throughout treatment
Epidemiology of Mycobacterium tuberculosis lineages and strain clustering within urban and peri-urban settings in Ethiopia
Background Previous work has shown differential predominance of certain Mycobacterium tuberculosis (M. tb) lineages and sub-lineages among different human populations in diverse geographic regions of Ethiopia. Nevertheless, how strain diversity is evolving under the ongoing rapid socio-economic and environmental changes is poorly understood. The present study investigated factors associated with M. tb lineage predominance and rate of strain clustering within urban and peri-urban settings in Ethiopia. Methods Pulmonary Tuberculosis (PTB) and Cervical tuberculous lymphadenitis (TBLN) patients who visited selected health facilities were recruited in the years of 2016 and 2017. A total of 258 M. tb isolates identified from 163 sputa and 95 fine-needle aspirates (FNA) were characterized by spoligotyping and compared with international M.tb spoligotyping patterns registered at the SITVIT2 databases. The molecular data were linked with clinical and demographic data of the patients for further statistical analysis. Results From a total of 258 M. tb isolates, 84 distinct spoligotype patterns that included 58 known Shared International Type (SIT) patterns and 26 new or orphan patterns were identified. The majority of strains belonged to two major M. tb lineages, L3 (35.7%) and L4 (61.6%). The observed high percentage of isolates with shared patterns (n = 200/258) suggested a substantial rate of overall clustering (77.5%). After adjusting for the effect of geographical variations, clustering rate was significantly lower among individuals co-infected with HIV and other concomitant chronic disease. Compared to L4, the adjusted odds ratio and 95% confidence interval (AOR; 95% CI) indicated that infections with L3 M. tb strains were more likely to be associated with TBLN [3.47 (1.45, 8.29)] and TB-HIV co-infection [2.84 (1.61, 5.55)]. Conclusion Despite the observed difference in strain diversity and geographical distribution of M. tb lineages, compared to earlier studies in Ethiopia, the overall rate of strain clustering suggests higher transmission and warrant more detailed investigations into the molecular epidemiology of TB and related factors

Network analysis of dairy cattle movement and associations with bovine tuberculosis spread and control in emerging dairy belts of Ethiopia
Background: Dairy cattle movement could be a major risk factor for the spread of bovine tuberculosis (BTB) in
emerging dairy belts of Ethiopia. Dairy cattle may be moved between farms over long distances, and hence
understanding the route and frequency of the movements is essential to establish the pattern of spread of BTB
between farms, which could ultimately help to inform policy makers to design cost effective control strategies. The
objective of this study was, therefore, to investigate the network structure of dairy cattle movement and its
influence on the transmission and prevalence of BTB in three emerging areas among the Ethiopian dairy belts,
namely the cities of Hawassa, Gondar and Mekelle.
Methods: A questionnaire survey was conducted in 278 farms to collect data on the pattern of dairy cattle
movement for the last 5 years (September 2013 to August 2018). Visualization of the network structure and analysis
of the relationship between the network patterns and the prevalence of BTB in these regions were made using
social network analysis.
Results: The cattle movement network structure display both scale free and small world properties implying local
clustering with fewer farms being highly connected, at higher risk of infection, with the potential to act as super
spreaders of BTB if infected. Farms having a history of cattle movements onto the herds were more likely to be
affected by BTB (OR: 2.2) compared to farms not having a link history. Euclidean distance between farms and the
batch size of animals moved on were positively correlated with prevalence of BTB. On the other hand, farms having
one or more outgoing cattle showed a decrease on the likelihood of BTB infection (OR = 0.57) compared to farms
which maintained their cattle.
Conclusion: This study showed that the patterns of cattle movement and size of animal moved between farms
contributed to the potential for BTB transmission. The few farms with the bulk of transmission potential could be
efficiently targeted by control measures aimed at reducing the spread of BTB. The network structure described can also
provide the starting point to build and estimate dynamic transmission models for BTB, and other infectious disease
High burden of hypertension across the age groups among residents of Gondar city in Ethiopia: a population based cross sectional study
Prevalence of bovine tuberculosis and its associated risk factors in the emerging dairy belts of regional cities in Ethiopia
Bovine tuberculosis (BTB) has become an economically important disease in dairy herds found in and around Addis Ababa City and is emerging in regional cities like Gondar, Hawassa and Mekelle because of the establishment of dairy farms in the milk sheds of these cities. A cross-sectional study to estimate the prevalence of BTB and identify associated risk factors was conducted between February 2016 and March 2017. A total of 174 herds comprising of 2,754 dairy cattle in the cities of Gondar, Hawassa and Mekelle were tested using the Single Intradermal Comparative Cervical Tuberculin (SICCT) test. Data on herd structure, animal origin, body condition, housing condition, farm hygiene, management and biosecurity practices were collected using a pre-tested structured questionnaire. Generalized Linear Models (GLM) and Generalized Linear Mixed Models (GLMM) were used to analyze the herd and animal level risk factors, respectively. The herd prevalence was 22.4% (95% CI: 17–29%) while the animal prevalence was 5.2% (95% CI: 4–6%) at the cut-off >4 mm. The herd prevalence rose to 65.5% (95% CI: 58–72%) and the animal prevalence rose to 9% (95% CI: 8–10%) when the severe interpretation of >2 mm cut-off was applied. The mean within-herd prevalence in positive farms at the cut-off >4 mm was 22.7% (95% CI: 15–31%). At the herd level, the analysis showed that herd size, farm hygiene, feeding condition and biosecurity were significantly associated with BTB status, while new cattle introductions showed only borderline significance and that age of farm, housing condition, farmers’ educational status and animal health care practice were not significant. At the animal level, the results showed that age and animal origin were identified as significant predictors for BTB positivity but sex and body condition score were not related to BTB status. Descriptive analysis revealed that herds having ‘BTB history’ showed slightly higher likelihood of being BTB positive compared to farms having no previous BTB exposure. In conclusion, this study showed relatively lower average prevalence in the emerging dairy regions as compared to the prevalence observed in and around Addis Ababa City, warranting for implementation of control program at this stage to reduce or possibly stop further transmission of BTB
