- 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.

How to improve clinical practice on involuntary hospital admissions of psychiatric patients : suggestions from the EUNOMIA study

- Number and procedures of involuntary hospital admissions vary in Europe according to the different socio-cultural contexts. The European Commission has funded the EUNOMIA study in 12 European countries in order to develop European recommendations for good clinical practice in involuntary hospital admissions. The recommendations have been developed with the direct and active involvement of national leaders and key professionals, who worked out national recommendations, subsequently summarized into a European document, through the use of specific categories. The need for standardizing the involuntary hospital admission has been highlighted by all centers. In the final recommendations, it has been stressed the need to: providing information to patients about the reasons for hospitalization and its presumable duration; protecting patients’ rights during hospitalization; encouraging the involvement of family members; improving the communication between community and hospital teams; organizing meetings, seminars and focus-groups with users; developing training courses for involved professionals on the management of aggressive behaviors, clinical aspects of major mental disorders, the legal and administrative aspects of involuntary hospital admissions, on communication skills. The results showed the huge variation of involuntary hospital admissions in Europe and the importance of developing guidelines on this procedure.

- Objective: Large numbers of psychiatric patients either are involuntarily admitted to hospital treatment or feel coerced despite a legally voluntary admission. For ethical and clinical reasons, their perceived coercion should be reduced as far as possible. There is however limited evidence on patient characteristics associated with perceived coercion during hospital treatment. This study aimed to identify i) sociodemographic and clinical characteristics associated with perceived coercion at admission and ii) changes in symptoms and global functioning associated with changes in perceived coercion over time.Method: Three thousand and ninety three in-patients who were involuntarily admitted or felt coerced to hospital treatment despite a legally voluntary admission were recruited in the European evaluation of coercion in psychiatry and harmonization of best clinical practice EUNOMIA project in 11 European countries. Perceived coercion, global functioning and symptoms were assessed after admission and at a 3-month follow-up.Results: Involuntary admission, female gender, poorer global functioning and more positive symptoms were associated with higher levels of perceived coercion at admission. Perceived coercion significantly decreased over time, and the improvements in global functioning and positive symptoms were associated with reduction in perceived coercion.Conclusion: Female patients perceive more coercion in psychiatric hospital treatment. Effective treatment for positive symptoms and improving patients global functioning may lead to a reduction in perceived coercion.

A New Class of Labile Surfactants that Break Down to Non-surface Active Products upon Heating or after a Pre-set Time, without the Need for a pH Change

- A new class of labile surfactants that break down at a controllable rate without the need for a change in pH will be presented. The invention has been patented by YKI Institute for Surface Chemistry, and is based on use of β-keto acids or their salts as surface-active compounds. These surfactants spontaneously break down through decarboxylation, to form an oil-like ketone and CO 2/HCO 3 -/CO 32 - depending on pH. The rate of breakdown can be controlled within a wide range by temperature or by certain additives, but, unlike most cleavable surfactants, a change in pH is not needed. Furthermore the surfactants can be conveniently activated from a stabile precursor just before use, and one (of many possible) precursors of this kind is already available on the industrial scale in the form of a wellknown chemical that is FDA-approved in other, non-surfactant, applications. The compound in question, alkyl ketene dimer (AKD), is produced in large scale by a number of large chemical producers today, and used for hydrophobization of paper. The present article gives an overview of the surfactant chemistry, with focus on recent studies of the kinetics of activation of the surfactant precursor and breakdown kinetics of the labile surfactant at different conditions. Furthermore, possible industrial applications of the surfactant will be discussed, with one example taken from a recent feasibility study performed within the car washing area. © Carl Hanser Publisher.

A novel modular and dispatchable CSP Stirling system : Design, validation, and demonstration plans

Konferensbidrag (refereegranskat)abstract
- This paper summarizes the preliminary results from the on-going development of a novel modular dispatchable solar power plant concept. The work encompasses techno-economic feasibility assessment, concept design, full scale sub-system tests and validation work, and ultimately plans for a fully integrated demonstration of the system. The proposed solar power plant concept consists of a heliostat field that powers a latent heat thermal energy storage (TES), fitted on a small tower. The solar receiver located underneath the TES tank, is an optical cavity with a small aperture that enables the concentrated sunlight to be emitted directly on the solar absorber surface while ensuring low convective and radiative losses. The stored thermal energy is provided to the engine, in proximity to the latent heat storage, with a pumped heat transfer fluid (HTF). The Stirling engine with a rated power of 13 kW has been modified and optimised for the operational conditions that the eutectic aluminum-silicon latent heat storage provides. For example, a new engine tubular gas heater has been developed for the HTF (i.e. sodium) and the expansion cylinder has been enlarged to improve both efficiency and power output as the temperature of the working gas is somewhat lower than in previous dish Stirling application. The choice of eutectic aluminum-silicon as TES media resulted from a thorough assessment of several phase change materials throughout the design phase of the project. Indeed, such a TES media selected would benefit from a suitable melting temperature of around 580°C, high energy density, high thermal conductivity, and low cost.
