Pediatric Emergencies in Helicopter Emergency Medical Services: A National Population-Based Cohort Study From Denmark.

STUDY OBJECTIVE: To examine the diagnostic pattern, level of severity of illness or injuries, and mortality among children for whom a physician-staffed helicopter emergency medical service (HEMS) was dispatched. METHODS: Population-based cohort study including patients aged less than 16 years treated by the Danish national HEMS from October 1, 2014, to September 30, 2018. Diagnoses were retrieved from inhospital medical records, and the severity of illness or injuries was assessed by a severity score on scene, administration of advanced out-of-hospital care, need for intensive care in a hospital, and mortality. RESULTS: In total, 651 HEMS missions included pediatric patients aged less than 1 year (9.2%), 1 to 2 years (29.0%), 3 to 7 years (28.3%), and 8 to 15 years (33.5%). A third of the patients had critical emergencies (29.6%), and for 20.1% of the patients, 1 or more out-of-hospital interventions were performed: intubation, mechanical chest compressions, intraosseous vascular access, blood transfusion, chest tube insertion, and/or ultrasound examination. Among the 525 patients with hospital follow-up, the most frequent hospital diagnoses were injuries (32.2%), burns (11.2%), and respiratory diseases (7.8%). Within 24 hours of the mission, 18.1% of patients required intensive care. Twenty-nine patients (5.1%, 95% confidence interval [CI] 3.6 to 7.3) died either on or within 1 day of the mission, and the cumulative 30-day mortality was 35 of 565 (6.2%, 95% CI 4.5 to 8.5) (N=565 first-time missions). CONCLUSION: On Danish physician-staffed HEMS missions, 1 in 5 pediatric patients required advanced out-of-hospital care. Among hospitalized patients, nearly one-fifth of the patients required immediate intensive care and 6.2% died within 30 days of the mission.

Usefulness of Imaging Response Assessment after Irreversible Electroporation of Localized Pancreatic Cancer-Results from a Prospective Cohort.

(1) Background: Irreversible electroporation (IRE) is a nonthermal ablation technique that is being studied in nonmetastatic pancreatic cancer (PC). Most published studies use imaging outcomes as an efficacy endpoint, but imaging interpretation can be difficult and has yet to be correlated with survival. The aim of this study was to examine the correlation of imaging endpoints with survival in a cohort of IRE-treated PC patients. (2) Methods: Several imaging endpoints were examined before and after IRE on 18F-fluorodeoxyglucose positron emission tomography (PET) with computed tomography. Separate analyses were performed at the patient and lesion levels. Mortality rate (MR) ratios for imaging endpoints after IRE were estimated. (3) Results: Forty-one patients were included. Patient-level analysis revealed that progressive disease (PD), as defined by RECIST 1.1, is correlated with a higher MR at all time intervals, but PD, as defined by EORTC PET response criteria, is only correlated with the MR in the longest interval. No correlation was found between PD, as defined by RECIST, and the MR in the lesion-level analysis. (4) Conclusions: Patient-level PD, as defined by RECIST, was correlated with poorer survival after IRE ablation, whereas no correlations were observed in the lesion-level analyses. Several promising lesion-level outcomes were identified.

Does training of general practitioners for intensive treatment of people with screen-detected diabetes have a spillover effect on mortality and cardiovascular morbidity in 'at risk' individuals with normoglycaemia? Results from the ADDITION-Denmark cluster-randomised controlled trial.

AIMS/HYPOTHESIS: Within a trial of intensive treatment of people with screen-detected diabetes, we aimed to assess a potential spillover effect of the trial intervention on incident cardiovascular disease (CVD) and all-cause mortality among people who screened positive on a diabetes risk questionnaire but who were normoglycaemic. METHODS: In the Anglo-Danish-Dutch Study of Intensive Treatment In People with Screen-Detected Diabetes in Primary Care (ADDITION)-Denmark trial, 175 general practices were cluster-randomised into: (1) screening plus routine care of individuals with screen-detected diabetes (control group); or (2) screening plus training and support in intensive multifactorial treatment of individuals with screen-detected diabetes (intervention group). We identified all individuals who screened positive on a diabetes risk questionnaire in ADDITION-Denmark but were normoglycaemic following biochemical testing for use in this secondary analysis. After a median 8.9 years follow-up, we used data from national registers to compare rates of first CVD events and all-cause mortality in individuals in the routine care group with those in the intensive treatment group. RESULTS: In total, 21,513 individuals screened positive for high risk of diabetes but were normoglycaemic on biochemical testing in ADDITION-Denmark practices between 2001 and 2006 (10,289 in the routine care group and 11,224 in the intensive treatment group). During 9 years of follow-up, there were 3784 first CVD events and 1748 deaths. The incidence of CVD was lower among the intensive treatment group compared with the routine care group (HR 0.92 [95% CI 0.85, 0.99]). This association was stronger among individuals at highest CVD risk (heart SCORE ≥ 10; HR 0.85 [95% CI 0.75, 0.96]). There was no difference in mortality between the two treatment groups (HR 1.02 [95% CI 0.92, 1.14]). CONCLUSIONS/INTERPRETATION: Training of general practitioners to provide target-driven intensive management of blood glucose levels and other cardiovascular risk factors showed some evidence of a spillover effect on the risk of CVD over a 9 year period among individuals at high risk of diabetes. The effect was particularly pronounced among those at highest risk of CVD. There was no effect on mortality. TRIAL REGISTRATION: ClinicalTrials.gov NCT00237549.
