- 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.

- In the present study, we investigate the crosslinking behaviour of 6 ordinary low density polyethylenes, and the effect of relatively modest changes in the polyethylene structure on the properties of the resulting network. The observed variations in gel formation are mainly explained by differences in molecular weight, where both M̄n and M̄w affect the results. The presence of long chain branches (LCB) present on the polymer main chain is shown to have a significant effect on the network quality. The occurrence of LCB affects the ability in making effective entanglements, a behaviour which is largely dependent on the length of the branches. At high LCB frequencies, the long chain branches are relatively short and therefore more prone to disentangle. The frequency and the amount of LCB, together with the molecular weight, have a large impact on the coil size. The coil size is believed to be an important parameter for the crosslinking behaviour, as a large coil size facilitates interconnections between adjacent polymer coils. In addition, LCB increases the probability of creating intramolecular crosslinks. However, this study shows that a very high amount of LCB is needed in order to obtain any significant effect on the network quality originating from intramolecular crosslinks. © 2005 Elsevier Ltd.

- We have shown that it is possible to regioselectively polymerize 3-(4-octylphenyl) thiophene with FeCl3. Adding FeCl3 slowly to the monomer leads to a soft and therefore regioselective polymerization. The head-to-tail content was determined by H-1 NMR to be 94 +/- 2%. Thin films of the polymer treated with chloroform vapor have an absorption maximum at 602 nm (2.06 eV) with clear vibronic fine structure. Free standing films have a conductivity of 4 S/cm, which is 100 times higher than for earlier prepared poly(3-(4-octylphenyl)thiophene). A mechanism for the regioregular polymerization is also proposed.

Attributes of person-centred communication : A qualitative exploration of communication with older persons in home health care

- Background: Previous research points to challenges related to the home healthcare of older persons and to the complexity of communication. Although person-centred care has been advocated widely, there remains a need for in-depth knowledge on how to enable person-centred and supportive communication in the care of older persons. Aim: The aim of this study was to explore attributes of person-centred communication between nurses and older persons being cared for in their home. Methods: A descriptive study with a qualitative approach was conducted. A data set from the COMHOME-study consisting of 77 audio-recorded home healthcare visits between registered nurses and older persons was analysed with a method for qualitative thematic analysis. Results: The findings indicate that the attributes of person-centred communication comprise recognising, inviting and involving older persons. To facilitate this form of communication, attentiveness and responsiveness on the part of RNs seemed significant. Person-centred communication was facilitated when the RNs used verbal expressions to emphasise and acknowledge the older persons’ views and were attentive to their emotions and expressions. Conclusion: The nurses’ attentiveness and responsiveness seems important for person-centred communication with older persons. Communication skills are needed to recognise, invite and involve older persons in their care and to support their health and well-being. Implication for practice The importance of communication which facilitate a person-centred approach by nurses should be acknowledged when caring for older persons and included in education and training.
