Is the Physician’s Behavior in Dyslipidemia Diagnosis in Accordance with Guidelines? Cross-Sectional Escarval Study
2013
Background: Clinical inertia has been defined as mistakes by the physician in starting or intensifying treatment when indicated. Inertia, therefore, can affect other stages in the healthcare process, like diagnosis. The diagnosis of dyslipidemia requires $ 2 high lipid values, but inappropriate behavior in the diagnosis of dyslipidemia has only previously been analyzed using just total cholesterol (TC). Objectives: To determine clinical inertia in the dyslipidemia diagnosis using both TC and high-density lipoprotein cholesterol (HDL-c) and its associated factors. Design: Cross-sectional. Setting: All health center visits in the second half of 2010 in the Valencian Community (Spain). Patient…
A barium method for the cytochemical detection of sulfated glycosaminoglycans in mast cells and basophilic leukocytes.
1999
Barium ions precipitate inorganic as well as organic sulfate compounds and they can be detected by a reaction with sodium rhodizonate. In this work, we describe the use of a barium method for the selective demonstration of sulfated glycosaminoglycans in cytoplasmic granules of mast cells and basophilic leukocytes. Methanol-fixed smears of mouse peritoneal mast cells and rat bone marrow basophils were treated with 5% BaCl2 for 10 min, followed by staining with either 0.2% sodium rhodizonate in 50% ethanol for 2 h at 60 degrees C, or 0.01% brilliant green in distilled water for 1 min. Light microscopic observation revealed a strong staining reaction of the cytoplasmic granules of these cell t…
Drilling dimension effects in early stages of osseointegration and implant stability in a canine model
2015
Background: This study histologically evaluated two implant designs: a classic thread design versus another specifically designed for healing chamber formation placed with two drilling protocols. Material and Methods: Forty dental implants (4.1 mm diameter) with two different macrogeometries were inserted in the tibia of 10 Beagle dogs, and maximum insertion torque was recorded. Drilling techniques were: until 3.75 mm (regular-group); and until 4.0 mm diameter (overdrilling-group) for both implant designs. At 2 and 4 weeks, samples were retrieved and processed for histomorphometric analysis. For torque and BIC (bone-to-implant contact) and BAFO (bone area fraction occupied), a general-linea…
High-sensitivity troponin assay improves prediction of cardiovascular risk in patients with cerebral ischaemia
2013
Background and purpose Clinical scores are recommended for predicting cardiovascular risk in patients with cerebral ischaemia to inform secondary prevention. Blood biomarkers may improve prediction beyond clinical scores. Methods Within the observational Find-AF trial (ISRCTN46104198), 197 patients >18 years of age with cerebral ischaemia and without atrial fibrillation had blood sampled at baseline. The predictive value of five biomarkers for a combined vascular endpoint (acute coronary syndrome, stroke, cardiovascular death) and all-cause mortality was determined, alone and in addition to the Essen Stroke Risk Score (ESRS), Stroke Prognostic Instrument 2 (SPI-2) and National Institutes of…
Patient Alert to detect ICD lead failure: efficacy, limitations, and implications for future algorithms.
2006
Aims An algorithm that alerts implantable cardioverter-defibrillator (ICD) patients, in case of abnormal lead impedance (Patient Alert™, Medtronic), may help to recognize lead dysfunction. We aimed to determine the utility of Patient Alert for ICD lead-failure detection in a prospective study. Methods and results Three hundred and sixty ICD patients were followed for 22±14 months. Patient Alert was active for pacing impedance 2000–3000 Ω, and high-voltage conductor impedance 200 Ω. Ten alert events and a total of 29 severe system complications occurred. Patient Alert detected three of 10 ICD lead failures, with a positive predictive value (PPV) of 77.8% for any severe system complication. R…
Diagnostic Accuracy and Usability of the ECG247 Smart Heart Sensor Compared to Conventional Holter Technology
2021
Background. Heart rhythm disorders, especially atrial fibrillation (AF), are increasing global health challenges. Conventional diagnostic tools for assessment of rhythm disorders suffer from limited availability, limited test duration time, and usability challenges. There is also a need for out-of-hospital investigation of arrhythmias. Therefore, the Norwegian ECG247 Smart Heart Sensor has been developed to simplify the assessment of heart rhythm disorders. The current study aimed to evaluate the diagnostic accuracy and usability of the ECG247 Smart Heart Sensor compared to conventional Holter monitors. Methods. Parallel tests with ECG247 Smart Heart Sensor and a Holter monitor were perform…
The Riga East University Hospital Stroke Registry—An Analysis of 4915 Consecutive Patients with Acute Stroke
2021
Background and Objectives: A hospital-based stroke registry is a useful tool for systematic analyses of the epidemiology, clinical characteristics, and natural course of stroke. Analyses of stroke registry data can provide information that can be used by health services to improve the quality of care for patients with this disease. Materials and Methods: Data were collected from the Riga East University Hospital (REUH) Stroke Registry in order to evaluate the etiology, risk factors, clinical manifestations, treatment, functional outcomes, and other relevant data for acute stroke during the period 2016–2020. Results: During a five-year period, 4915 patients (3039 females and 1876 males) with…
Atrial fibrillation in Mediterranean spotted fever
2008
Mediterranean spotted fever (MSF) is a tick-borne acute febrile disease caused by Rickettsia conorii and characterized by fever, maculo-papular rash and a black eschar at the site of the tick bite (‘tache noir’). We describe the case of a 58-year-old man affected by MSF who developed atrial fibrillation. The patient presented himself to the hospital after 7 days of fever, malaise and severe headache. Cardiac auscultation revealed a chaotic heart rhythm and an electrocardiogram confirmed atrial fibrillation with a fast ventricular response. Diagnosis of MSF was made after the appearance of a maculo-papular skin rash, and treatment with oral doxycycline was started. An immunofluorescence anti…
Previous antibacterial treatment due to concomitant infections in preschool children is associated with a lower Helicobacter pylori positivity
2005
Use of antimicrobial agents has been proposed as 1 of the factors that contribute to the loss of Helicobacter pylori (H. pylori) infection. The aim of the study was to investigate the influence of a previous treatment with antibiotics on the prevalence of H. pylori infection in preschool children. Parents of 146 asymptomatic children (aged 0.5-5 y; no antibiotic treatment during the previous 4 weeks) completed a questionnaire about previous treatment with antibiotics and socioeconomic status. Infection with H. pylori was assessed by the monoclonal stool antigen test. H. pylori positivity was 18% (27/146). It was significantly lower in children who had been treated with antibiotics previousl…
Prognostic value of hyperattenuating middle cerebral artery sign at CT in cerebral infarction
2004
To assess the prognostic value of hyperattenuating middle cerebral artery sign at CT in acute cerebral infarction.Ninety-two patients with acute cerebral infarction in the sylvian area were retrospectively reviewed. All patients underwent unenhanced CT 12-24 hours after the onset of symptoms and follow-up CT within 48-72 hours. Initial CT scans were evaluated by consensus by three radiologists to confirm or exclude the presence of hyperattenuating middle cerebral artery sign. History, cardiovascular risk factors and neurological impairment at discharge (mean 25 days) were recorded for each patient. The degree of disability was graded 0 (no disability) to 6 (death). Patients were divided int…
