Time-and-motion tool for the assessment of working time in tuberculosis laboratories: a multicentre study

SETTING: Implementation of novel diagnostic assays in tuberculosis (TB) laboratory diagnosis requires effective management of time and resources. OBJECTIVE: To further develop and assess at multiple centres a time-and-motion (T&M) tool as an objective means for recording the actual time spent on running laboratory assays. DESIGN: Multicentre prospective study conducted in six European Union (EU) reference TB laboratories. RESULTS: A total of 1060 specimens were tested using four laboratory assays. The number of specimens per batch varied from one to 60; a total of 64 recordings were performed. Theoretical hands-on times per specimen (TTPS) in h:min:s for Xpert® MTB/RIF, mycobacterial interspersed repetitive unit-variable number of tandem repeats genotyping, Ziehl-Neelsen staining and manual fluorescence microscopy were respectively 00:33:02 ± 00:12:32, 00:13:34 ± 00:03:11, 00:09:54 ± 00:00:53 and 00:06:23 ± 00:01:36. Variations between laboratories were predominantly linked to the time spent on reporting and administrative procedures. Processing specimens in batches could help save time in highly automated assays (e.g., line-probe) (TTPS 00:14:00 vs. 00:09:45 for batches comprising 7 and 31 specimens, respectively). CONCLUSIONS: The T&M tool can be considered a universal and objective methodology contributing to workload assessment in TB diagnostic laboratories. Comparison of workload between laboratories could help laboratory managers justify their resource and personnel needs for the implementation of novel, time-saving, cost-effective technologies, as well as identify areas for improvement

Templates Implementation for Structured DICOM Diagnosis Reporting in

We previously reported the development of a DICOM structured diagnosis application allowing efficient storage and retrieval of echocardiographic information. Reports are generated for every patient and every type of information is stored into a complex database. For such a structure to be efficiently use in the echocardiography laboratory, we extended EchoSection template with a description section including a EchoDescription template allowing generation of echocardiographic reports for every cardiac structure. This was possible by using parameters and by developing a simple programming language for specifying complex relationships between different rows of the template. We are currently generating reports for a large variety of cardiac diseases and storing them into a DICOM image database. 1

Takotsubo Cardiomyopathy presenting as ST-elevation myocardial infarction: wide triggering spectrum and specific echocardiographical pattern in a consecutive case series report.

We report a series of six consecutive cases of Takotsubo Cardiomyopathy (TCM) presenting as ST-elevation acute myocardial infarction and consequently addressed to the emergency coronary angiography, inside a time-frame of one year (2015). This series underlines the wide possible triggering spectrum and clinical severity of TCM and recognizes echocardiography as an essential imaging technique in the diagnosis due to its widespread availability and feasibility in the acute care setting.</jats:p

Endovascular Treatment for Acute Mesenteric Ischaemia in a Young Woman with Polyarterial Disease

Background: Acute mesenteric ischaemia is a condition with a grim prognosis on conservative treatment. Endovascular revascularisation is a promising approach for some of these patients.Case report: We present the case of a 44-year-old woman with a history of severe arterial hypertension, left leg claudication, and overlooked symptoms of chronic mesenteric ischaemia for one year, who was admitted for severe abdominal pain for one week. Computed tomographic angiography (CTA) showed acute mesenteric ischaemia by occlusion of the coeliac trunk and the superior mesenteric artery (SMA), without bowel perforation. In addition, CTA showed tight left renal stenosis and left external iliac stenosis. We performed angioplasty with a stent of the SMA, followed by revascularisation of the left renal artery. On control injection, the SMA appeared re-occluded, requiring a second stent implantation and a loading dose of dual antiplatelet therapy, with a good final result. Subsequently, the clinical course was uneventful, with no need of surgical exploration; a second procedure was planned, aiming at iliac revascularisation. At one month, the patient was asymptomatic, with normal Doppler flow in the SMA. Angiographic control during iliac revascularisation procedure showed a permeable SMA with a good filling of the coeliac trunk territory. Because of the suspicion of fibro-muscular dysplasia as aetiology, coronary angiography and cerebral CTA were performed, in order to exclude other potential lesions.Conclusions: Endovascular revascularisation in AMI is a promising alternative to the surgical approach in patients presenting without bowel perforation. Nevertheless, its safety and many tactical details remain to be clarified. Existing networks for revascularisation in acute myocardial infarction may be useful for the implementation of this approach.Abbreviations: AMI: Acute Mesenteric Ischaemia; CTA: Computed Tomographic Angiography; ICU: Intensive Care Unit; SMA: Superior Mesenteric Artery; STEMI: ST-segment Elevation Myocardial Infarction.</jats:p

Epidemiology of peripheral artery disease in Europe : VAS educational paper

This paper reviews the current epidemiological data on peripheral artery disease (PAD) in Europe. Cardiovascular disease (CVD) burden is presented and PAD prevalence is discussed, as compared to coronary (CAD) and cerebrovascular (CeVD) diseases, in European Union (EU) countries and European continent countries. The article reviews PAD clinical manifestations, PAD diagnosis, risk factors for PAD incidence and progression, PAD prognosis and financial implications. CVD mortality is higher in women than in men and in European continent countries, as compared to EU countries. While CAD and CeVD have a lower prevalence in EU countries, as compared to the whole continent, PAD and other CVDs still have a higher prevalence in EU countries. PAD prevalence vary widely between countries, increases sharply with aging and has a relation with ethnicity. CVD comorbidities are high in PAD subjects and particularly high in those with critical limb ischemia. PAD prognosis is related to CAD and CeVD mortality, that are particularly high in critical limb ischemia. This review promotes the need for global awareness on PAD burden, stimulates PAD screening and emphasizes the importance of early diagnosis and treatment of PAD and associated cardiovascular comorbidities
