INTRODUCTION: Interventional oncology locoregional therapies are validated treatment modalities for primary and secondary tumors in liver, lung, kidney and bone. At this time, there is no accordance in the choice of imaging modality to assess treatment response. Morphological imaging and RECIST 1.1 criteria based on size variation are limited by several critical points. On the other hand the role of functional imaging, in particular by [18F]-fluorodeoxyglucose ([18F]-FDG) positron emission tomography (PET), in both staging and response evaluation of locoregional treatments remains unclear because of the heterogeneous nature of available data...

Background The reported incidence rate of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is 0.3%. However, routine use of intraoperative cholangiography (IOC) is a controversial, due to the additional cost and radiation exposure. The aim of this study was to assess the application of fluorescence cholangiography (FC) in comparison to IOC and to LC without any intraoperative imaging. Materials and Methods This prospective study included 230 patients undergoing LC in our institution. The subjects were divided into two groups...

Foamed hydroxyapatite offers a three-dimensional scaffold for the development of bone constructs, mimicking perfectly the in vivo bone structure. In vivo, calcium release at the surface is assumed to provide a locally increased gradient supporting the maintenance of the hematopoietic stem cells niche. We fabricated hydroxyapatite scaffolds with high surface calcium concentration by infiltration, and used human umbilical vein endothelial cells (HUVECs) as a model to study the effects on hematopoietic lineage direction...

This study aimed to identify health-promoting contents focused on HIV/Aids prevention in messages posted in a Facebook group for debates on the use of pre-exposure prophylaxis (PrEP). This was a prospective observational study using systematic non-participant observation. From July 2015 to June 2016, all the posts in the group were catalogued and formed a corpus. Everything was processed in IRaMuTeQ and analyzed by descending hierarchical classification. The collected data were grouped in three classes: (1) HIV/Aids prevention: discussing prophylaxis, treatment, target public, and side effects; (2) universal access to PrEP in Brazil: discussing government responsibilities; (3) on-line purchase of truvada: exposing a situation of vulnerability...

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common inflammatory disorder associated with lower airway disease. However, only few studies of CRSwNP from outside secondary/tertiary care centres have been published. We recently reported an asthma frequency of 44% and 65% in primary and secondary care patients respectively. Therefore, we hypothesise that inflammation of the lower airways could be present in all CRSwNP patients, even without asthma. Here, we assessed the degree of lower and upper airway inflammation using exhaled and nasal nitric oxide (NO) in primary care CRSwNP patients with and without asthma...

BACKGROUND: Hereditary haemorrhagic telangiectasia (HHT) remains a difficult disease for the ENT specialist to manage. Affected patients often report recurrent epistaxis as the most debilitating symptom. The pathogenesis of the disease is due to genetic mutations affecting angiogenesis. For this reason, the anti-angiogenic therapy bevacizumab has gained popularity in the local treatment of epistaxis in patients with HHT. OBJECTIVE: A systematic review of the efficacy of bevacizumab in local treatment of epistaxis in patients with HHT based on epistaxis duration, frequency, severity and impact on quality of life...

Studies over the past three decades have shown that learning difficulties are not only determined by neurological disorders, but also by motivational and/or socio-cognitive factors Among these factors, implicit theories of intelligence (also referred to as conceptions, mindsets or beliefs about intelligence) are key elements. The belief that intelligence is fixed (entity theory), as opposed to malleable (incremental theory), is generally associated with negative teaching practices and poorer student outcomes, yet beliefs about the intelligence of individuals with intellectual disabilities have not received much attention...

Purpose Pancreatic cystic lesions are common incidental findings on imaging, but up to half may be forerunners of pancreatic cancer. Therefore, accurate differential diagnosis is crucial for correct patient management. Unfortunately, currently available diagnostic methods cannot robustly identify premalignant and malignant pancreatic cystic lesions. Methods Cyst fluid samples obtained by routine endoscopic ultrasound-guided aspiration were used for the analyses. In a cohort of 24 patients, eight biomarker candidates for malignant potential and high-grade dysplasia/cancer were identified by an explorative proteomic approach...

Intradialytic hypotension (IDH) remains the most frequent severe side effect of hemodialysis. This prospective, exploratory study aimed to measure the compliance of an IDH prevention pathway and to identify the effects of pathway use on hypotension incidence. Additionally, the study explored barriers and facilitators to pathway implementation in five hemodialysis centers. Instituting an ultrafiltration pause decreased the odds of hypotensive episodes by 44% (OR = 0.56, 95% CI = 0.20 to 1.56, χ2 1 = 1.25, p = 0...

BACKGROUND: Measurement of radioactive iodine uptake (RAIU) is an important aspect of the assessment and treatment of patients with hyperthyroidism. Its uncertainty affects how much of a true change in RAIU can be detected as well as appropriateness of the therapy dosage upon which it is based. In this study, a method of estimating the reproducibility and least significant change (LSC) values for RAIU measurements, and the implications of the values observed are discussed, with emphasis on application to quality assurance initiatives...

BACKGROUND: Diffusion-weighted imaging (DWI) has been studied in breast imaging and can provide more information about diffusion, perfusion and other physiological interests than standard pulse sequences. The stretched-exponential model has previously been shown to be more reliable than conventional DWI techniques, but different diagnostic sensitivities were found from study to study. PURPOSE: This work investigated the characteristics of whole-lesion histogram parameters derived from the stretched-exponential diffusion model for benign and malignant breast lesions, compared them with conventional apparent diffusion coefficient (ADC), and further determined which histogram metrics can be best used to differentiate malignant from benign lesions...
