- Background Therapeutic hypothermia (TH) is a promising treatment of stroke, but limited data are available regarding the safety and effectiveness of cooling methodology. We investigated the safety of TH and compared the cooling capacity of two widely used cooling strategies endovascular and surface cooling. Methods COOLAID Oresund is a bicentre randomized trial in Copenhagen (Denmark) and Malmo (Sweden). Patients were randomized to either TH (33 degrees C for 24h) in a general intensive care unit (ICU) or standardized stroke unit care (control). Cooling was induced by a surface or endovascular-based strategy. Results Thirty-one patients were randomized. Seven were cooled using endovascular and 10 using surface-based cooling methods and 14 patients received standard care (controls). 14 (45%) patients received thrombolysis. Pneumonia was recorded in 6 (35%) TH patients and in 1 (7%) control. 4 TH patients and 1 control developed massive infarction. 1 TH patient and 2 control suffered asymptomatic haemorrhagic transformation. Mortality was comparable with 2 (12%) in the TH group and 1 (7%) among controls. Mean (SD) duration of hospital stay was 25.0days (24, 9) in TH and 22.5days (20.6) in control patients (P=0.767). Mean (SD) induction period (cooling onset to target temperature) was 126.3min (80.6) with endovascular cooling and 196.3min (76.3) with surface cooling (P=0.025). Conclusions Therapeutic hypothermia with general anaesthesia is feasible in stroke patients. We noticed increased rates of pneumonia, while the length of hospital stay remained comparable. The endovascular cooling strategy provides a faster induction period than surface cooling.

- Background: Myocardial dysfunction occurs commonly in septic shock. It is not known whether this is due to local ischaemia and metabolic disturbances. Our hypothesis was that endotoxaemic myocardial dysfunction may be associated with interstitial ischaemic and metabolic changes, measured using interstitial microdialysis (MD). Methods: Eighteen pigs were randomized to control (n=6) or endotoxin infusion (n=12). MD catheters were inserted into the myocardium for measurement of interstitial glucose, pyruvate and lactate concentrations. Plasma glucose and lactate concentrations and systemic haemodynamic parameters were measured simultaneously. Results: Compared with the control group, the endotoxaemic animals had significantly decreased left ventricular stroke work and venous oxygen saturation (SvO2), and increased mean pulmonary artery pressure and plasma lactate. In the endotoxaemic group, decreases in interstitial glucose were observed, occurring simultaneously with increases in interstitial pruvate. Interstitial lactate : pyruvate ratios decreased with time in all animals. Conclusions: Despite severe systemic and pulmonary haemodynamic changes, interstitial MD measurements revealed no evidence of anaerobic metabolism in the myocardium of endotoxaemic pigs. There were, however, changes in glucose and pyruvate concentrations, suggesting local energy metabolic disturbances. © 2008 The Authors.

- Child healthcare (CHC) nurses have a key role in promoting and supporting healthy lifestyle behaviors from a young age. Thus, this study aims to investigate the perspectives of CHC nurses regarding discussing food introduction, physical activity/active play, and screen time with parents; explore facilitators and barriers influencing the discussion of healthy lifestyle behaviors with parents; and explore the perspectives of CHC nurses regarding a complementary program to promote healthy lifestyle behaviors from the start of life. A total of fifteen nurses participated in semi-structured interviews, which were recorded, transcribed verbatim, and analyzed using thematic analysis. There were four themes that were generated: parental needs; facilitators and barriers; parental groups; and future working methods. This study found that CHC nurses have seen an increase in the need for support among today's parents. Time, the need to tailor information, and confidence to address sensitive topics were perceived as the largest barriers during daily work for the nurses. Furthermore, large variations in parental groups were found. Finally, the CHC nurses displayed a willingness and openness to change and develop current working methods using digital solutions. These solutions could possibly ease the workload and at the same time, support parents to create healthy lifestyle behaviors from the start of their child's life.

- Background: Becoming critical ill or severely injured leads to a process of worry, anxiety and pain. Patients in intensive care sometimes have strange and frightening experiences and may show symptoms of acute confusion or delirium. CAM-ICU, the confusion assessment method for the intensive care unit, was based on the DSM IV, the Diagnostic and Statistic Manual of Mental Disorders IV, and today, healthcare professionals and researchers are increasingly accepting this concept of diagnosing ICU delirium. In Sweden, there is no commonly used, single instrument or method to test the development of ICU delirium. The aim of this study was to translate, retranslate and validate CAM-ICU for use in Swedish ICU settings. Methods: The translation of the instrument was done according to the guidelines suggested by The Translation and Cultural Adaptation group which includes preparation, forward translation/reconciliation, back translation, back translation review, harmonization, cognitive debriefing and validation. In the validation process, the applicability of the Swedish version of the instruments was tested in a Swedish intensive care unit. Results: Fourteen adult patients were included in the study, 40 paired tests were carried out, and 80 CAM-ICU instruments were completed. The participating patients were given CAM-ICU ratings using independent paired evaluations by two nurses, specialized in intensive care, at least twice during the patients' stay in the ICU. Interrater reliability was calculated using kappa statistics. In the 40 paired observations, interrater reliability was 'very good' (kappa statistics > 0.81). In our material, we recognized a delirium rate of 48%, which is in accordance with previous studies. Conclusion: The translation of the instrument CAM-ICU showed good correlation with the original version and could therefore be applicable in a Swedish ICU setting. In the 40 paired observations, interrater reliability was very good. Although there are limitations in using CAM-ICU, previous studies reveal a need for a homogeneous screening instrument making it possible to detect and determine ICU delirium; and from this basis are able to implement and make the necessary decisions required in medical and nursing care practice preventing ICU delirium.
