Hypomineralized Second Primary Molars as Predictor of Molar Incisor Hypomineralization
2016
AbstractMolar incisor hypomineralization (MIH) is a developmental defect of dental enamel that shares features with hypomineralized second primary molars (HSPM). Prior to permanent tooth eruption, second primary molars could have predictive value for permanent molar and incisor hypomineralization. To assess this possible relationship, a cross-sectional study was conducted in a sample of 414 children aged 8 and 9 years from the INMA cohort in Valencia (Spain). A calibrated examiner (linear-weighted Kappa 0.83) performed the intraoral examinations at the University of Valencia between November 2013 and 2014, applying the diagnostic criteria for MIH and HSPM adopted by the European Academy of …
Assessment of a qualitative serological assay to screen for allergic sensitization in elderly subjects
2013
We used a commercially available specific IgE qualitative serological assay to screen for allergic sensitization. Two hundred twenty-eight elderly subjects took part in the study. Skin-prick tests (SPTs) to a panel of relevant aeroallergens present in the study area were used as the diagnostic reference procedure (gold standard). Subjects with at least one positive SPT (≥3 mml n = 76) were considered to have developed an allergic sensitization. The qualitative assay correctly classified subjects as sensitized to an allergen or not sensitized in 257 of 288 cases (accuracy, 88.9%; 95% CI, 85.0-92.0%). The qualitative assay sensitivity was 70.0 (95% CI, 58.1-79.7) and specificity was 95.7 (95%…
Computed Tomography-Aortography Versus Color-Duplex Ultrasound for Surveillance of Endovascular Abdominal Aortic Aneurysm Repair: A Prospective Multi…
2020
Background Color-duplex ultrasonography (DUS) could be an alternative to computed tomography-aortography (CTA) in the lifelong surveillance of patients after endovascular aneurysm repair (EVAR), but there is currently no level 1 evidence. The aim of this study was to assess the diagnostic accuracy of DUS as an alternative to CTA for the follow-up of post-EVAR patients. Methods Between December 16, 2010, and June 12, 2015, we conducted a prospective, blinded, diagnostic-accuracy study, in 15 French university hospitals where EVAR was commonly performed. Participants were followed up using both DUS and CTA in a mutually blinded setup until the end of the study or until any major aneurysm-rel…
The accuracy of flexible spectral imaging colour enhancement for the diagnosis of gastric intestinal metaplasia
2014
Background Targeting biopsies on the basis of visual recognition of mucosal changes in the stomach instead of the currently accepted random biopsy sampling may be attractive. Aim The aim of this study was to evaluate the accuracy of endoscopic findings using flexible spectral imaging colour enhancement (FICE) for intestinal metaplasia (IM) in the gastric mucosa. Methods A consecutive cohort of 126 individuals aged over 50 years (27% men) was subjected to upper endoscopy using FICE. Histological assessment (per patient and per biopsy) was considered the gold standard to accuracy estimates. Results Histological assessment revealed IM in 50% of the individuals [OLGIM (operative link on gastric…
Cardiac Troponins for the Diagnosis of Acute Myocardial Infarction in Chronic Kidney Disease
2018
Background Patients with chronic kidney disease ( CKD ) are at high risk of myocardial infarction. Cardiac troponins are the biomarkers of choice for the diagnosis of acute myocardial infarction ( AMI ) without ST ‐segment elevation ( NSTE ). In patients with CKD , troponin levels are often chronically elevated, which reduces their diagnostic utility when NSTE ‐ AMI is suspected. The aim of this study was to derive a diagnostic algorithm for serial troponin measurements in patients with CKD and suspected NSTE ‐ AMI . Methods and Results Two cohorts, 1494 patients from a prospective cohort study with high‐sensitivity troponin I (hs‐ cTnI ) measurements and 7059 cases from a clinical registr…
PROGNOSTIC VALUE OF LUNG ULTRASOUND IN OLDER NURSING HOME RESIDENTS AFFECTED BY COVID-19
2020
Objectives: Lung ultrasonographic (LUS) imaging may play an important role in the management of patients with COVID-19–associated lung injury, particularly in some special populations. However, data regarding the prognostic role of the LUS in nursing home residents, one of the populations most affected by COVID-19, are not still available. Design: Retrospective. Settings and Participants: Nursing home residents affected by COVID-19 were followed up with an LUS from April 8 to May 14, 2020, in Chioggia, Venice. Methods: COVID-19 was diagnosed through a nasopharyngeal swab. LUS results were scored using a 12-zone method. For each of the 12 zones (2 posterior, 2 anterior, 2 lateral, for both l…
Independent Validation of Sepsis Index for Sepsis Screening in the Emergency Department
2021
(1) Background: The early detection of sepsis is still challenging, and there is an urgent need for biomarkers that could identify patients at a high risk of developing it. We recently developed an index, namely the Sepsis Index (SI), based on the combination of two CBC parameters: monocyte distribution width (MDW) and mean monocyte volume (MMV). In this study, we sought to independently validate the performance of SI as a tool for the early detection of patients at a high risk of sepsis in the Emergency Department (ED). (2) Methods: We enrolled all consecutive patients attending the ED with a request of the CBC. MDW and MMV were measured on samples collected in K3-EDTA tubes on the UniCel …
Reliability of automatic detection of AHI during positive airway pressure treatment in obstructive sleep apnea patients: A “real-life study”
2021
Introduction: Automatic event detection (AED) of residual apnea-hypopnea index (AHI) by ventilators is a current practice in sleep and mechanical ventilation Units but this methodology has not been validated in an unselected population of OSA patients. Aim of the present study was to assess in a “real-life” condition the reliability of AED during PAP therapy by the in-built software compared to full polysomnography during follow-up. Methods: We enrolled 300 OSA patients (105 F; AHI 45.3 ± 27.8) already on Positive airway pressure (PAP) therapy: 53% of the patients were on CPAP while other modalities were used in the rest of the sample. Results: Overall, the built-in software identified resi…
Global validation of the WSES Sepsis Severity Score for patients with complicated intra-abdominal infections : a prospective multicentre study (WISS …
2015
BACKGROUND: To validate a new practical Sepsis Severity Score for patients with complicated intra-abdominal infections (cIAIs) including the clinical conditions at the admission (severe sepsis/septic shock), the origin of the cIAIs, the delay in source control, the setting of acquisition and any risk factors such as age and immunosuppression. ----- METHODS: The WISS study (WSES cIAIs Score Study) is a multicenter observational study underwent in 132 medical institutions worldwide during a four-month study period (October 2014-February 2015). Four thousand five hundred thirty-three patients with a mean age of 51.2 years (range 18-99) were enrolled in the WISS study. ----- RESULTS: Univariate…
Fatty liver indexandhepatic steatosis index for prediction ofnon-alcoholic fatty liver disease in type 1 diabetes
2017
Background and Aim Little is known about the diagnostic value of hepatic steatosis index (HSI) and fatty liver index (FLI), as well as their link to metabolic syndrome in type 1 diabetes mellitus. We have screened the effectiveness of FLI and HSI in an observational pilot study of 40 patients with type 1 diabetes. Methods FLI and HSI were calculated for 201 patients with type 1 diabetes. Forty patients with FLI/HSI values corresponding to different risk of liver steatosis were invited for liver magnetic resonance study. In-phase/opposed-phase technique of magnetic resonance was used. Accuracy of indices was assessed from the area under the receiver operating characteristic curve. Results Tw…
