- 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.

Conference paper (peer-reviewed)abstract
- Fast internet access is not obvious in rural areas and when it is time to install we realize that houses are built with special materials. The properties of these materials affect the electromagnetic wave propagation in a different way than the houses in the cities. In this work, we perform an analysis of signal quality in 700-MHz and 900-MHz bands for 3G and 4G communication systems for adobe buildings. Three different adobe wall scenarios were analyzed: conventional adobe, adobe doped with salt and adobe doped with coal. Then two kind of measurements have been carried out, the first one a Network Vector Analyzer (VNA) and two HyperLOG antenna were used and in the second one a Samsung S8 with the software from TEMS Pocket 16.3.7.26 was used. Wave propagation and signal quality measurements made on adobe walls provide satisfactory results showing large variation in attenuation and signal quality due to the material used in adobe.
