The Asthma Mobile Health Study, a large-scale clinical observational study using ResearchKit

Abstract. This paper presents an observational study of the tornado outbreak that took place on the 7 September 2005 in the Llobregat delta river, affecting a densely populated and urbanised area and the Barcelona International airport (NE Spain). The site survey confirmed at least five short-lived tornadoes. Four of them were weak (F0, F1) and the other one was significant (F2 on the Fujita scale). They started mostly as waterspouts and moved later inland causing extensive damage estimated in 9 million Euros, three injured people but fortunately no fatalities. Large scale forcing was provided by upper level diffluence and low level warm air advection. Satellite and weather radar images revealed the development of the cells that spawned the waterspouts along a mesoscale convergence line in a highly sheared and relatively low buoyant environment. Further analysis indicated characteristics that could be attributed indistinctively to non-supercell or to mini-supercell thunderstorms.

Risk And Resilience

Abstract The Hamburg City Health Study (HCHS) is a large, prospective, long-term, population-based cohort study and a unique research platform and network to obtain substantial knowledge about several important risk and prognostic factors in major chronic diseases. A random sample of 45,000 participants between 45 and 74 years of age from the general population of Hamburg, Germany, are taking part in an extensive baseline assessment at one dedicated study center. Participants undergo 13 validated and 5 novel examinations primarily targeting major organ system function and structures including extensive imaging examinations. The protocol includes validate self-reports via questionnaires regarding lifestyle and environmental conditions, dietary habits, physical condition and activity, sexual dysfunction, professional life, psychosocial context and burden, quality of life, digital media use, occupational, medical and family history as well as healthcare utilization. The assessment is completed by genomic and proteomic characterization. Beyond the identification of classical risk factors for major chronic diseases and survivorship, the core intention is to gather valid prevalence and incidence, and to develop complex models predicting health outcomes based on a multitude of examination data, imaging, biomarker, psychosocial and behavioral assessments. Participants at risk for coronary artery disease, atrial fibrillation, heart failure, stroke and dementia are invited for a visit to conduct an additional MRI examination of either heart or brain. Endpoint assessment of the overall sample will be completed through repeated follow-up examinations and surveys as well as related individual routine data from involved health and pension insurances. The study is targeting the complex relationship between biologic and psychosocial risk and resilience factors, chronic disease, health care use, survivorship and health as well as favorable and bad prognosis within a unique, large-scale long-term assessment with the perspective of further examinations after 6 years in a representative European metropolitan population.

The Impact

ObjectivesOut-of-hours (OOH) telephone triage is used to manage patient flow, but knowledge of the communicative skills of telephone triagists is limited. The aims of this study were to compare communicative parameters in general practitioner (GP)-led and nurse-led OOH telephone triage and to discuss differences in relation to patient-centred communication and safety issues.DesignObservational study.SettingTwo Danish OOH settings: a large-scale general practitioner cooperative in the Central Denmark Region (n=100 GP-led triage conversations) and Medical Helpline 1813 in the Capital Region of Denmark (n=100 nurse-led triage conversations with use of a clinical decision support system).Participants200 audio-recorded telephone triage conversations randomly selected.Primary and secondary outcome measuresConversations were compared with regard to length of call, distribution of speaking time, question types, callers’ expression of negative affect, and nurses’ and GPs’ responses to callers’ negative affectivity using the Mann-Whitney U test and the Student’s t-test.ResultsCompared with GPs, nurses had longer telephone contacts (137s vs 264 s, p=0.001) and asked significantly more questions (5 vs 9 questions, p=0.001). In 36% of nurse-led triage conversations, triage nurses either transferred the call to a physician or had to confer the call with a physician. Nurses gave the callers significantly more spontaneous talking time than GPs (23.4s vs 17.9 s, p=0.01). Compared with nurses, GPs seemed more likely to give an emphatic response when a caller spontaneously expressed concern; however, this difference was not statistically significant (36% vs 29%, p=0.6).ConclusionsWhen comparing communicative parameters in GP-led and nurse-led triage, several differences were observed. However, the impact of these differences in the perspective of patient-centred communication and safety needs further research. More knowledge is needed to determine what characterises good quality in telephone triage communication.

Bronchiectasis is one of the most neglected diseases in respiratory medicine. There are no approved therapies and few large-scale, representative epidemiological studies.The EMBARC (European Multicentre Bronchiectasis Audit and Research Collaboration) registry is a prospective, pan-European observational study of patients with bronchiectasis. The inclusion criterion is a primary clinical diagnosis of bronchiectasis consisting of: 1) a clinical history consistent with bronchiectasis; and 2) computed tomography demonstrating bronchiectasis. Core exclusion criteria are: 1) bronchiectasis due to known cystic fibrosis; 2) age <18 years; and 3) patients who are unable or unwilling to provide informed consent.The study aims to enrol 1000 patients by April 2016 across at least 20 European countries, and 10 000 patients by March 2020. Patients will undergo a comprehensive baseline assessment and will be followed up annually for up to 5 years with the goal of providing high-quality longitudinal data on outcomes, treatment patterns and quality of life. Data from the registry will be available in the form of annual reports. and will be disseminated in conference presentations and peer-reviewed publications.The European Bronchiectasis Registry aims to make a major contribution to understanding the natural history of the disease, as well as guiding evidence-based decision making and facilitating large randomised controlled trials.
