Background: The low level of patient satisfaction recorded in many studies and, at the same time, the level of frustration and burnout, disclosed by medics in the perception of the patient as a ‘problem’, incline to look for the causes of inadequate relationship between physician and patient. Objective: The aim of this study was to evaluate the level of acceptance of the patient by the medical personnel. The research problem was the acceptance level which was within the range of the communication skills of the nurses and doctors...

Platelet indices could mirror megakaryopoietic activity in immune thrombocytopenic purpura (ITP), but its specificity and sensitivity need to be studied. The diagnostic performance of platelet indices was analyzed by receiver-operating characteristic curves, and the probability of true positive (sensitivity) and true negative (specificity) in predicting ITP, myelodysplasia, or controls was determined. Mean platelet volume (MPV) was higher, whereas plateletcrit (PCT) was significantly lower in ITP than in myelodysplasia and controls...

BACKGROUND: Human T-lymphotropic virus type I (HTLV-I) is known to be associated with neoplastic and neurodegenerative changes, and it is believed to be associated with various systemic inflammatory diseases, including Sjögren's syndrome (SS). Although HTLV-I infection is endemic in Brazil, there is no information regarding the association between HTLV-I infection and SS in the Brazilian population. The objective of this study was to determine the prevalence of SS in HTLV-I-infected individuals and the prevalence of HTLV-I-infection in individuals diagnosed with SS...

The present study is the first attempt to report the characterization of a nucleotidase from Cerastes cerastes venom. A 70 kDa 5'-nucleotidase (Cc-5'NTase) was purified to homogeneity. The amino acid sequence of Cc-5'NTase displayed high homology with many nucleotidases. Its activity was optimal at pH 7 with a specific hydrolytic activity toward mono-, di-, and triphosphate adenylated nucleotides. Cc-5'NTase preferentially hydrolyzed ADP and obeyed Michaelis-Menten kinetics. Among the metals and inhibitors tested, Ni(2+) and Mg(2+) completely potentiated enzyme activity, whereas EGTA, PMSF, iodoacetamide, vanillic acid, vanillyl mandelic acid, and 1,10-phenanthroline partially abolished its activity...

In psychophysiological research, bootstrapping procedures are often used to classify individual participants. How many iterations are required for a reliable bootstrap test is not universally agreed upon. To investigate the number of iterations needed for a stable bootstrap estimate, we reanalyzed P300 data collected in concealed information test paradigms. We also distinguished between the bootstrap and permutations approaches. We compared results in several studies using 100 versus 1,000 versus 10,000 iterations in the bootstrap, and we concluded that 100 iterations were adequate as results from all three iteration numbers correlated highly...

OBJECTIVES: In traditional surface rendering (SR) Computed tomographic endoscopy, only shape of endoluminal lesion is depicted without gray level information unless the volume rendering technique is used. However volume rendering technique is relatively slow and complex in terms of computation time and parameter setting. We use computed tomographic colonography (CTC) images as examples and report a new visualization technique by three dimensional (3D) gray level mapping (GM) to better identify and differentiate endoluminal lesions...

Although contemporary high-throughput -omics methods produce high-dimensional data, the resulting wealth of information is difficult to assess using traditional statistical procedures. Machine learning methods facilitate the detection of additional patterns, beyond the mere identification of lists of features that differ between groups.Here, we demonstrate the utility of (1) supervised classification algorithms in class validation, and (2) unsupervised clustering in class discovery. We use data from our previous work that described the transcriptional profiles of gingival tissue samples obtained from subjects suffering from chronic or aggressive periodontitis (1) to test whether the two diagnostic entities were also characterized by differences on the molecular level, and (2) to search for a novel, alternative classification of periodontitis based on the tissue transcriptomes...

BACKGROUND:  Usually, immunoglobulin M (IgM) serologic analysis is not sufficiently specific to confirm Zika virus (ZIKV) infection. However, since IgM does not cross the placenta, it may be a good marker of infection in neonates. METHODS:  We tested blood from 42 mothers and neonates with microcephaly and collected cerebrospinal fluid (CSF) specimens from 30 neonates. Molecular assays were performed for detection of ZIKV, dengue virus, and chikungunya virus; IgM enzyme-linked immunosorbent assays and plaque-reduction neutralization tests (PRNTs) were performed to detect ZIKV and dengue virus...

BACKGROUND: Thyroid nodules are usually diagnosed using fine-needle aspiration (FNA). The sensitivity limitations of FNA result in 10-30% of nodules being classified as "indeterminate". The BRAF(V600E) mutation is associated with papillary thyroid carcinoma (PTC). We conducted a systemic review and meta-analysis to evaluate the diagnostic utility of the BRAF(V600E) mutation in indeterminate nodules. METHOD: PUBMED and EMBASE were searched for studies testing for the BRAF(V600E) involving indeterminate nodules (Thy3a, Thy3f, Thy4) and containing information on final surgical histopathology...
