- Background: Child health is a key priority on the global health agenda, yet the provision of essential and emergency surgery in children is patchy in resource-poor regions. This study was aimed to determine the mortality risk for emergency abdominal paediatric surgery in low-income countries globally.Methods: Multicentre, international, prospective, cohort study. Self-selected surgical units performing emergency abdominal surgery submitted prespecified data for consecutive children aged <16 years during a 2-week period between July and December 2014. The United Nation's Human Development Index (HDI) was used to stratify countries. The main outcome measure was 30-day postoperative mortality, analysed by multilevel logistic regression.Results: This study included 1409 patients from 253 centres in 43 countries; 282 children were under 2 years of age. Among them, 265 (18.8%) were from low-HDI, 450 (31.9%) from middle-HDI and 694 (49.3%) from high-HDI countries. The most common operations performed were appendectomy, small bowel resection, pyloromyotomy and correction of intussusception. After adjustment for patient and hospital risk factors, child mortality at 30 days was significantly higher in low-HDI (adjusted OR 7.14 (95% CI 2.52 to 20.23), p<0.001) and middle-HDI (4.42 (1.44 to 13.56), p=0.009) countries compared with high-HDI countries, translating to 40 excess deaths per 1000 procedures performed.Conclusions: Adjusted mortality in children following emergency abdominal surgery may be as high as 7 times greater in low-HDI and middle-HDI countries compared with high-HDI countries. Effective provision of emergency essential surgery should be a key priority for global child health agendas.

Chronic Noncommunicable Diseases in 6 Low-and Middle-Income Countries : Findings From Wave 1 of the World Health Organization's Study on Global Ageing and Adult Health (SAGE)

- In this paper, we examine patterns of self-reported diagnosis of noncommunicable diseases (NCDs) and prevalences of algorithm/measured test-based, undiagnosed, and untreated NCDs in China, Ghana, India, Mexico, Russia, and South Africa. Nationally representative samples of older adults aged >= 50 years were analyzed from wave 1 of the World Health Organization's Study on Global Ageing and Adult Health (2007-2010; n = 34,149). Analyses focused on 6 conditions: angina, arthritis, asthma, chronic lung disease, depression, and hypertension. Outcomes for these NCDs were: 1) self-reported disease, 2) algorithm/measured test-based disease, 3) undiagnosed disease, and 4) untreated disease. Algorithm/measured test-based prevalence of NCDs was much higher than self-reported prevalence in all 6 countries, indicating underestimation of NCD prevalence in low-and middle-income countries. Undiagnosed prevalence of NCDs was highest for hypertension, ranging from 19.7% (95% confidence interval (CI): 18.1, 21.3) in India to 49.6% (95% CI: 46.2, 53.0) in South Africa. The proportion untreated among all diseases was highest for depression, ranging from 69.5% (95% CI: 57.1, 81.9) in South Africa to 93.2% (95% CI: 90.1, 95.7) in India. Higher levels of education and wealth significantly reduced the odds of an undiagnosed condition and untreated morbidity. A high prevalence of undiagnosed NCDs and an even higher proportion of untreated NCDs highlights the inadequacies in diagnosis and management of NCDs in local health-care systems.

Cost-Effectiveness of School-Based Prevention of Cannabis Use

Tidskriftsartikel (refereegranskat)abstract
- Background: Cannabis is the most frequently used illicit drug globally. Despite increasing evidence that cannabis use is associated with adverse health effects, the knowledge on preventative strategies is still limited. This study stemmed from a systematic review of effective prevention in which school-based programmes were identified as promising. The primary objective was to evaluate the cost effectiveness of Project ALERT (Adolescent, Learning, Experiences, Resistance, and Training), compared with ordinary ATOD (Alcohol, Tobacco, and Other Drug) education, among Swedish students in the eighth grade of compulsory school.Methods: The cost-effectiveness analysis was performed from the societal perspective with quality-adjusted lifeyears (QALYs) as an outcome (willingness-to-pay threshold €50,000) and follow-up periods from 1 year to a lifetime, considering a discounting rate of 3 %, and with costs inflated to 2013 levels. A Markov model was constructed on the basis of the ‘states’ of single use, regular use, daily use and use of other illicit drugs, which were associated with ‘complications’ of psychosis, schizophrenia, traffic accidents, depression and amotivational syndrome. Health and cost consequences were linked to both states and complications.Results: The programme was cost saving on the basis of evidence from the USA (ratio 1:1.1), and was cost effective (incremental cost-effectiveness ratio €22,384 per QALY) after reasonable adjustment for the Swedish context and with 20 years of follow-up. When the target group was restricted to boys who were neither studying nor working/doing work experience, the programme was cost effective after 9 years and cost saving (ratio 1:3.2) after 20 years.Conclusion: School-based prevention such as Project ALERT has the potential to be cost effective and to be cost saving if implemented in deprived areas. In the light of the shifting landscape regarding legalization of cannabis, it seems rational to continue the health economic analysis of prevention initiated here.

Power generation based on agricultural residues gasification : The potential of corncobs
- 2017

Ingår i: European Biomass Conference and Exhibition Proceedings 2017. - : ETA-Florence Renewable Energies. ; , s. 90-95

Konferensbidrag (refereegranskat)abstract
- Interest in biomass-based power generation has increasingly grown during the last decade. Yet, the majority of current biomass gasification projects producing heat and power use wood as raw material in developed countries and sugar cane bagasse and palm oil residues in countries such as Colombia. There is an identified need for diversifying biomass sources that guarantee at least a cost- benefit ratio similar to that for wood gasification processes and promote their implementation in tropical areas. Currently there is no practical experience of this technology that is reported in Colombia and the use of corncobs for power generation is a new approach to utilize the biomass potential in this context. Our goal is to analyze the potential of corncobs for power generation through gasification. The analysis is performed using a case study in the largest wholesale market of Colombia, where not only residues are generated but electricity is required to carry out commercial activities. With a production of three tons of corncobs per day, our estimate indicates a potential to cover about 42% of the actual electricity consumption in the wholesale market. In a first stage we characterize corncobs. Then, we evaluate power generation at laboratory scale for different corncobs loads. Finally, we develop a techno-economic analysis to estimate the Levelized Cost of Electricity – LCOE corresponding to this particular technology in the context of Colombia. Different process variables for a constant load of 12 kW were used in a downdraft gasifier coupled to an internal combustion engine (18 kW installed capacity). It was obtained a LCOE of 0,17 USD/kWh which is lower than the price of electricity currently charged at 0,18 UDS/kWh.
