Project description:Studies that assess the distribution of benefits provided by ecosystem services across urban areas are increasingly common. Nevertheless, current knowledge of both the supply and demand sides of ecosystem services remains limited, leaving a gap in our understanding of balance between ecosystem service supply and demand that restricts our ability to assess and manage these services. The present study seeks to fill this gap by developing and applying an integrated approach to quantifying the supply and demand of a key ecosystem service, carbon storage and sequestration, at the local level. This approach follows three basic steps: (1) quantifying and mapping service supply based upon Light Detection and Ranging (LiDAR) processing and allometric models, (2) quantifying and mapping demand for carbon sequestration using an indicator based on local anthropogenic CO2 emissions, and (3) mapping a supply-to-demand ratio. We illustrate this approach using a portion of the Twin Cities Metropolitan Area of Minnesota, USA. Our results indicate that 1735.69 million kg carbon are stored by urban trees in our study area. Annually, 33.43 million kg carbon are sequestered by trees, whereas 3087.60 million kg carbon are emitted by human sources. Thus, carbon sequestration service provided by urban trees in the study location play a minor role in combating climate change, offsetting approximately 1% of local anthropogenic carbon emissions per year, although avoided emissions via storage in trees are substantial. Our supply-to-demand ratio map provides insight into the balance between carbon sequestration supply in urban trees and demand for such sequestration at the local level, pinpointing critical locations where higher levels of supply and demand exist. Such a ratio map could help planners and policy makers to assess and manage the supply of and demand for carbon sequestration.

Project description:BackgroundThe health sectors success has been determined by consistent and reasonably priced health commodities supply. Despite possible death from the disease, Tuberculosis (TB) can be prevented with early diagnosis and appropriate treatment for which enough, effective, and qualified medicines need to be available. However, studies revealed stock of anti-TB drugs in health facilities. Here we present the recent finding on determinants of stock out of Anti-TB drug at public health facilities of Addis Ababa.ObjectiveThis study aimed to identify determinants of stock outs of first line anti TB drugs at public health facilities under Addis Ababa City Administration Health Bureau.MethodMixed study design were employed. A total of 106 facilities were included in the sampling frame and data were collected from the study population such as drug store managers of health facilities providing TB treatment using semi structured questionnaire and through in-depth interview with Addis Ababa hubs of the Ethiopian Pharmaceuticals Supply Agency (EPSA), Addis Ababa City Administration Health Bureau and selected heads of pharmacy departments of health facilities from May 1-30, 2020 considering one year back retrospective data from March 20,2019 to March 20,2020. Structured record review of data from Logistics Management Information System (LMIS) tools having TB drugs was done using structured observation checklist. Data were entered, cleaned, and analyzed using SPSS Version 20. Both descriptive and multiple logistic regression analysis were performed.Result52(62.7%) of health facilities encountered stock out for at least one of these drugs during the past 1 year. Rifampicin 75 mg + Isoniazid 50 mg (RH 75/50 mg) were most stocked out first line anti-TB drug from 33(39.8%) of facilities with 17 mean stocks out days while Rifampicin 75 mg + Isoniazid 50 mg + Pyrazinamide 150 mg (RHZ 75/50/150 mg) were the least first line anti-TB drug stocked out from facilities with mean 5 days of stock out. Delayed supply of anti TB drug from EPSA, delivery of reduced quantity of anti TB drugs by EPSA and stocked out of anti TB Drugs at EPSA were significant determinate factors of stock out of first line anti-TB drug from facilities with 95%CI of 10.34(2.167-49.329), 11.452(2.183-60.079) and 5.646(1.240-25.707) respectively.ConclusionAbove median of health facilities encountered stock out of first line anti-TB drug in Addis Ababa. Delayed supply of anti TB drug from EPSA, delivery of reduced quantity of anti TB drugs by EPSA and stocked out of anti TB Drugs at EPSA were significant determinate factor of stocked out of first line anti-TB drug from facilities. EPSA and other responsible bodies shall work collaboratively to improve their service and ensure availability of adequate amount of Anti TB drug in health facilities.

Project description:Tumour hypoxia is a well-recognised barrier to anti-cancer therapy and represents one of the best validated targets in oncology. Previous attempts to tackle hypoxia have focussed primarily on increasing tumour oxygen supply; however, clinical studies using this approach have yielded only modest clinical benefit, with often significant toxicity and practical limitations. Therefore, there are currently no anti-hypoxia treatments in widespread clinical use. As an emerging alternative strategy, we discuss the relevance of inhibiting tumour oxygen metabolism to alleviate hypoxia and highlight recently initiated clinical trials using this approach.

Project description:Urban parks provide multiple non-material benefits to human health and well-being; measuring these "intangible" benefits mainly co-produced by the spatial interactivity between dwellers and urban parks is vital for urban green space management. This paper introduced "vitality" to measure the intangible benefits of urban parks and constructed a straightforward and spatially explicit approach to assess the park vitality based on visiting intensity and recreational satisfaction rate. Freely available data of check-in comments on parks, points-of-interest (POIs), and other multi-source data from Beijing were used to assess the urban park vitality and explore the factors influencing it from the perspectives of recreational service supply, demand, and spatial linking characteristics. We found that the urban park vitalities decreased along the urban-rural gradient. The presence of water and facility density in the parks have significant positive impacts on park vitality, and high population density nearby was a positive factor. Moreover, the external higher levels of the POI-based urban function mix and density, as well as developed public transportation, were strongly associated with greater park vitality. Our research proposed a feasible and effective method to assess the park vitality, and the findings from this study have significant implications for optimizing the spatial configuration of urban parks.

Project description:IntroductionCancer is an emerging public health problem in Ethiopia, with breast and cervical cancers accounting for over half of all newly diagnosed cancers in women. The majority of women with breast and cervical cancer are diagnosed at late stage of the disease and most patients do not receive care consistent with global standards. However, little is known about the health-seeking behaviours, barriers to early detection and treatment, patient-reported outcomes, financial burden and survival of women with breast and cervical cancer in the country. Therefore, this study aims to document the experience of women with breast and cervical cancer from recognition of symptoms to diagnosis, treatment and survivorship/mortality in Addis Ababa city, Ethiopia.Methods and analysisA prospective follow-up study using mixed methods (both quantitative and qualitative) will be employed. All women newly diagnosed with breast and cervical cancer from 1 January, 2017 to 30 June 2018 in Addis Ababa will be included in the study. Interviewer-administered questionnaires will be used to collect information about medical consultations after recognition of symptoms, health-seeking behaviours, treatment received, barriers to early detection and treatment, and survivorship care. In-depth interview will be conducted on purposefully selected women with breast and cervical cancer. The primary outcomes of the study are time intervals (patient and diagnostic waiting times), stage at diagnosis and survival. Multivariable analysis will be employed to determine the contributions of independent variables on the outcomes of interest. HRs with 95% CIs will be calculated for time-to-event outcomes. Qualitative data will be analysed using thematic analysis.Ethics and disseminationThis protocol is ethically approved by Institutional Review Board of Addis Ababa University. Verbal informed consent will be obtained from study participants. Results will be disseminated in international peer-reviewed journals and presented in relevant conferences.

Project description:BackgroundMidwives are the primary source of care and support for mothers and newborns at the most vulnerable time in their lives.The Ethiopian National Reproductive Health Strategy targeted reduction of Maternal Mortality rate to 267/100,000 live births in the years 2006-2015. Midwives play a crucial role in the care of pregnant women, from the first antenatal visit right through to the delivery and the postpartum period.MethodologyInstitution based cross-sectional study was carried out from March 2015 to April 2015 in Addis Ababa city, Ethiopia to assess job satisfaction and its determinants among midwives working at government health facilities. A total of 234 midwives were involved from 84 health centers and 8 governmental hospitals proportional to the size of health centers and hospitals using simple random sampling method. A total of 175 and 59 midwives were taken from health centers and government hospitals respectively. Different variables like Socio demographic, Job related domain and Organizational domain were collected using pre structured questionnaire after getting written consent. Data entry and analysis were done using SPSS 21.00. Binary logistic regression was used to determine factors affecting job satisfaction. P-values less than 0.05 were considered statistically significant.ResultFrom 234 eligible respondents 221 midwives participated in this study which makes a response rate of 94.44%. The overall mean job satisfaction was 52.9%. Independent predictors of job satisfaction includes Sex [AOR = 4.07 (95%CI: 1.36-12.37)], working unit [AOR = 0.04 (95%CI:(0.001-0.45)], Educational status [AOR = 5.74(95%CI: 1.48-40.47)], Marital status [AOR = 3.48 [1.01-11.97)], supervision [AOR = 4.33 (95%CI: 1.53-20.22)], standard of care[AOR 4.80, (3.38-50.10)] and work load [AOR 8.94, (95%CI 2.37-22.65)]. Midwives were least satisfied from salary, extrinsic reward and professional opportunity subscales while they were most satisfied from coworker relation and the standard of care they provided to clients.ConclusionHalf of study subjects were satisfied with their job. Governmental and Nongovernmental organizations should consider the factors that contribute to job dissatisfaction in order to improve service provision.

Project description:Declines in insect pollinators across Europe have raised concerns about the supply of pollination services to agriculture. Simultaneously, EU agricultural and biofuel policies have encouraged substantial growth in the cultivated area of insect pollinated crops across the continent. Using data from 41 European countries, this study demonstrates that the recommended number of honeybees required to provide crop pollination across Europe has risen 4.9 times as fast as honeybee stocks between 2005 and 2010. Consequently, honeybee stocks were insufficient to supply >90% of demands in 22 countries studied. These findings raise concerns about the capacity of many countries to cope with major losses of wild pollinators and highlight numerous critical gaps in current understanding of pollination service supplies and demands, pointing to a pressing need for further research into this issue.

Project description:Although homeless segment of the society could be the hotspots for tuberculosis (TB) transmission, there is little data on TB in homeless individuals in Ethiopia. The objective of this study was to investigate the molecular epidemiology and drug sensitivity of Mycobacterium tuberculosis (M. tuberculosis) isolated from homeless individuals in Addis Ababa, Ethiopia. The study was conducted on 59 M. tuberculosis isolates, which were recovered by the clinical screening of 5600 homeless individuals and bacteriological examination of 641 individuals with symptoms of pulmonary tuberculosis (PTB). Region of difference-9 (RD9) based polymerase-chain reaction (PCR), Spoligotyping and 24-loci Mycobacterial Interspersed Repetitive Unit-Variable Number Tandem Repeat (MIRU-VNTR) typing were used for genotyping of the isolates. In addition, drug sensitivity test was performed on the isolates using BD Bactec Mycobacterial Growth Inhibition Tube (MGIT) 960. Fifty-eight of the 59 isolates were positive by spoligotyping and spoligotyping International type (SIT) 53, SIT 37, and SIT 149 were the dominant spoligotypes; each consisting of 19%, 15.5%, and10.3% of the isolates, respectively. The majority of the isolates (89.7%) were members of the Euro-American (EA) major lineage. MIRU-VNTR identified Ethiopia_3, Delhi/CAS, Ethiopia_2, TUR, X-type, Ethiopia_H37Rv-like strain, Haarlem and Latin-American Mediterranean (LAM) sub lineages. The proportion of clustering was 77.6% (45/58) in spoligotyping while it was 39.7% (23/58) in 24-loci MIRU-VNTR typing. Furthermore, the proportion of clustering was significantly lowered to 10.3% (6/58) when a combination of spoligotyping and 24-loci MIRU-VNTRplus was used. The recent transmission index (RTI) recorded by spoligotyping, 24-loci MIRU-VNTR typing, and a combination of the two genotyping methods were 58.6%, 27.6% and 5.2%, respectively. Young age and living in groups were significantly associated with strain clustering (P < 0.05). The drug sensitivity test (DST) result showed 8.9% (4/58) of the isolates were resistant to one or more first line ant-TB drugs; but multidrug resistant isolate was not detected. Clustering and RTI could suggest the transmission of TB in the homeless individuals, which could suggest a similar pattern of transmission between homeless individuals and the general population. Hence, the TB control program should consider homeless individuals during the implementation of TB control program.

Project description:BackgroundHealthcare waste management is very important due to its hazardous nature that can cause risk to human health and the environment. In developing countries, healthcare waste has not received much attention and has been disposed of together with municipal waste. The aim of the study was to assess the healthcare waste management practices in Addis Ababa City Administration Public Health Facilities.MethodsAn institutional-based cross-sectional design was used for the study at Addis Ababa city 15 Public health centres and 3 hospitals. Data were collected using self-administered questionnaires distributed to 636 randomly selected healthcare waste handlers and managers. Observational check list also used. The data were entered into the EPI- INFO version TM 7 and exported to IBM SPSS 20 for analysis. Both descriptive and analytic statistics were employed.ResultsAmong the respondents, 358 (90.86%) from health centres and 96.38% (133) from hospitals indicated that their facilities had separate containers for hazardous and non-hazardous waste however, 61 (15.48%) from health centres and 29 (21.01%) from hospitals indicated that healthcare waste containers were not clearly marked or labelled. The study found that the main forms of on-site treatment of healthcare waste for health centres and hospitals before disposal were burning. Manager respondents from the health centres 65 (92.86%), 64 (91.43%) and from hospitals 31 (91.18%), 30 (88.24%) indicated that healthcare waste handlers were used protective clothing when handling waste and were provided with protective clothing when handling healthcare waste respectively.ConclusionIn this study healthcare waste management among healthcare waste handlers and healthcare facility managers were not getting full attention. Collection of healthcare waste were not done regularly, containers were not clearly marked and were not located in appropriate areas where they might be needed. Support healthcare waste handlers by training help to improve their knowledge, attitude and practice.

Project description:BACKGROUND:In 2005, Ethiopia changed its abortion law to curb its high maternal mortality. This has led to a considerable reduction in deaths from unsafe abortions. Abortion is now legal if the woman's pregnancy is a result of rape or incest, if her health is endangered, if the fetus has a serious deformity, if she suffers from a physical or mental deficiency, or if she is under 18 years of age. The word of the woman, if in compliance with the law, is sufficient to qualify for an abortion. In this context, where the law makes the door slightly open, health workers become important in deciding who gets access to safe services and who doesn't, thus creating considerable ethical dilemmas. METHODS:The objective of this study was to explore abortion service providers' personal experiences and reflections, perceptions of the abortion law, and ethical and dilemmas that arise. Data collection took place from March to May 2016 in Addis Ababa, at different health clinics providing abortion services. Thirty in-depth interviews and three focus group discussions were conducted with 41 abortion service providers at governmental and non-governmental clinics. Content analysis was drawn upon in the interpretation of the findings. RESULTS:When working in a context where the law has slightly opened the door for abortion seeking women, the health workers describe conflicting concerns, burdensome responsibilities, and ambiguity concerning how to interpret and implement the law. They describe efforts to balance their religious faith and values against their professional obligations and concern for women's health and well-being. This negotiation is particularly evident in the care of women who fall outside the law's indications. They usually handle ethical dilemmas and decision-making alone without guidance. Moreover, many health workers face a stigma from fellow colleagues not performing abortions and therefore keep their job a secret from family and friends. CONCLUSIONS:Health workers in Ethiopia experience ethical dilemmas trying to maneuver between the abortion law, their personal values, and their genuine concern for the health of women. More research is needed to further explore this.
