1. Systematic review on fecal calprotectin in cystic fibrosis
Abstract Objectives: Fecal calprotectin is an inflammatory marker used for monitoring intestinal diseases. It has been studied as a marker of intestinal inflammation in cystic fibrosis (CF), a multi-systemic genetic disease caused by alterations to the CFTR gene. Manifestations of the disease favor a systemic inflammation not limited to the respiratory trac

2. Sparse Estimation of the Precision Matrix and Plug-In Principle in Linear Discriminant Analysis for Hyperspectral Image Classification
ABSTRACT In this paper, a new method for supervised classification of hyperspectral images is proposed for the case in which the size of the training sample is small. It consists of replacing in the Mahalanobis distance the maximum likelihood estimator of the precision matrix by a sparse estimator. The method is compared with two other existing versions of L

3. ANALYSIS OF BENZODIAZEPINES IN PLASMA SAMPLES BY DLLME AND LC-DAD: CRITICAL ASPECTS, FLAWS AND ISSUES ENCOUNTERED - A DISCUSSION
Dispersive liquid-liquid microextraction (DLLME) is a fast and simple technique and applicable procedure for the analysis of xenobiotics in different biological matrices. We have developed a DLLME method for the determination of benzodiazepines in plasma samples using liquid chromatography-diode-array detection (LC-DAD). During method validation, relative st

4. Airway management following head and neck microvascular reconstruction: is tracheostomy mandatory?
Abstract Objectives: Airway management following maxillofacial microvascular reconstruction is a fundamental part of the perioperative management. In oral cavity microvascular reconstruction, the airway is potentially compromised by airway edema, flap edema or bulkiness, hematoma formation, or upper airway sequelae from surgery. Classical teaching advocates

5. Self-reported depression and anxiety among COPD patients. A case-control study
Abstract BACKGROUND: Anxiety and depression are the most prevalent mental disorders worldwide. However, the exact mechanisms linking chronic obstructive pulmonary disease (COPD) with depression and anxiety have not been identified. OBJECTIVES: To compare self-reported depression and anxiety among patients diagnosed with COPD in relation to healthy controls

6. Correlation between PET-CT and ct in the staging after the treatment of head and neck squamous cell carcinoma
Abstract Objective: The aim of this study is to find out if a single imaging test is enough to follow-up on an oncological post-treatment patient. In such a case, we would know which was more valuable after comparing the two, by CT or PET-CT. Methods: Between January 2012 and July 2018, we collected data from all patients with previous medical history who

7. VAAFT PROCEDURE (Video-assisted Anal Fistula Treatment) versus Open Method in the Treatment of High Fistula in Ano
Abstract Background A common acquired anorectal condition is anal fistula. The treatment approaches that have been employed have been linked to erratic outcomes and sometimes life-threatening consequences. Video-assisted anal fistula treatment (VAAFT), a minimally invasive method, was introduced for adult patients in 2011. Objective To know the efficacy of

8. Sebaceous nevus of Jadassohn: review and clinical-surgical approach
Abstract Background: Nevus sebaceous of Jadassohn is defined as a rare congenital malformation characterized as a non-hereditary hamartoma of the adnexal structures of the skin. Its etiology is not yet well understood, but it is believed to be related to post-zygotic mutations in the HRAS, NRAS and KRAS genes. Objective: To describe the clinical manifestat

9. Optimization Techniques and Mathematical Modeling Applied to Reluctance Motors
Abstract The present work aims at the application of different optimization strategies in the electromagnetic analysis of the Variable Reluctance Motor (VRM) through Finite Element (FE) simulation. Two case studies are investigated: the first one aims to optimize the geometry and electrical characteristics of windings of a single-phase VRM 6/6, minimizing co

10. Unplanned dilution back analysis in an underground mine using numerical models
Abstract In underground mines, stability problems can cause unplanned dilution, increasing the costs of mining operations, such as loading, transport, crushing and grinding. This is usually dealt with by simply increasing investments with support. However, the design geometry of stopes and drifts also has a great effect on a stope’s stability. The use of e
