Background/Aims: The invasiveness of a liver biopsy and its inconsistent results have prompted efforts to develop noninvasive tools to evaluate the severity of chronic hepatitis. This study was intended to assess the performance of serum biomarkers for predicting liver fibrosis in patients with chronic viral hepatitis. Methods: A total of 302 patients with chronic hepatitis B or C, who had undergone liver biopsy, were retrospectively enrolled. We investigated the diagnostic accuracy of several clinical factors for predicting advanced fibrosis (F≥3)...

Brazilian public policy on drugs has been permeated by two diametrically opposing approaches: one focusing on prohibition and the other on non- prohibition. Similarly, there have been two opposing approaches to mental healthcare, one centered on hospitalization and the other psychosocial care and development. In the context of these different paradigms, this article presents an analysis of twenty-two documents sourced by the legislative rules over the last sixteen years. After the year 2000, a renewed focus by healthcare community on drugs was noticeable as was the immersion of a harm reducing approach...

Background: Oral lichen planus is a potentially malignant disorder. One of the malignant transformation markers is cancer stem cells. One of the proposed marker for the detection of cancer stem cells's in head and neck cancer is aldehyde dehydrogenase. Recently it is shown that aldehyde dehydrogenase 1 expression in tissue samples is associated with oral lichen planus malignant transformation. Objective: This study evaluates salivary aldehyde dehydrogenase 1 in oral lichen planus...

RESUMEN Diseases like diabetes mellitus (DM) and hypertension (HT) generate high costs and are the most common cause of mortality in the Americas. In the case of Peru, given demographic and epidemiological changes, particularly the alarming increase in overweight and obesity, the burden of these diseases is constantly increasing, resulting in the need to budget more financial resources to the health services. The total care costs of these diseases and their complications represent a financial burden that should be considered very carefully by health institutions when they draft their budgets...

In recent decades, overweight or obesity have increased dramatically in middle- and low-income countries; a situation which consolidates chronic non-communicable diseases (NCD) as one of the leading causes of mortality and disability worldwide. Currently, half the people in Peru over the age of 15 years are overweight, and one fifth suffer from obesity. The situation is worsening and increasingly affects people in poverty, who frequently benefit from food supplement programs designed to combat food insecurity and malnutrition...

This study aimed to test the diagnostic performance of a fully quantitative fibrosis assessment tool for liver fibrosis in patients with chronic hepatitis B (CHB), primary biliary cirrhosis (PBC) and non-alcoholic steatohepatitis (NASH). A total of 117 patients with liver fibrosis were included in this study, including 50 patients with CHB, 49 patients with PBC and 18 patients with NASH. All patients underwent liver biopsy (LB). Fibrosis stages were assessed by two experienced pathologists. Histopathological images of LB slices were processed by second harmonic generation (SHG)/two-photon excited fluorescence (TPEF) microscopy without staining, a system called qFibrosis (quantitative fibrosis) system...

Purpose: To verify the auditory processing abilities and occurrence of the suppression effect of Otoacoustic Emissions (OAE) in individuals who stutter. Methods: The study sample comprised 15 adult individuals who stutter, aged 18-40 years, with stuttering severity ranging from mild to severe, paired according to gender, age, and schooling with individuals without speech complaint or disorder. All participants underwent conventional clinical evaluation, specific stuttering assessment, and basic (audiometry, imitanciometry, and measurement of acoustic reflexes) and specific (auditory processing evaluation and measurement of suppression effect of OAEs) audiological assessments...

Purpose: To describe a new model of actinic enteritis that does not use radiotherapy machines. Methods: Sixteen Wistar rats were divided into four groups, consisting of four animals each: control (group A), two weeks after irradiation (group B), five weeks after irradiation (group C) and eight weeks after irradiation (group D). Animals were given a 10Gy radiation from a Cobalt-60 natural source in a nuclear technology research center. Protections of the surrounding tissues were obtained through the usage of plumb devices with a hole in the center, which served as a collimator...

Purpose: To evaluate the effect of aqueous extract of Baccharis trimera leaves on the proliferative capacity of the liver after partial hepatectomy (PH) in rats. Methods: Twenty Wistar rats weighing between 300 and 450g were divided into two groups: control (HP) and test (HP100-rats that received the aqueous extract of Baccharis trimera for four days at a dose of 100 mg / kg / day). On the fifth day, animals from both groups underwent resection of 70% of the liver...

This study aimed to analyze TV food advertising in Brazil based on the recommendations of the Food Guide for the Brazilian Population, 2014. Programming from the four most popular TV channels was recorded on two non-consecutive days in January 2014. The commercials were categorized in (i) foods and beverages, (ii) restaurants, and (iii) non-food services, goods, and products, with those in the first category subdivided according to recommendations in the food guide. The commercials' categories were described by means of their frequency (and 95% confidence interval), for all the records and according to the day of the week...

We aimed to estimate the prevalence and correlates of psychotropic polypharmacy in Brazilian psychiatric patients by gender. Sociodemographic, behavioral and clinical data were obtained through face-to-face interviews and medical charts of 2,475 patients. Psychotropic polypharmacy was defined as the use of two or more psychotropic drugs and occurred in 85.7% of men (95%CI: 83.6%-87.6%) and 84.9% of women (95%CI: 82.8%-86.8%; p > 0.05). The mean number of psychotropic drugs/patient was 2.98 ± 1.23 and most common combinations included antipsychotics...

Metabolic reprogramming by oncogenic signals promotes cancer initiation and progression. The oncogene KRAS and tumour suppressor STK11, which encodes the kinase LKB1, regulate metabolism and are frequently mutated in non-small-cell lung cancer (NSCLC). Concurrent occurrence of oncogenic KRAS and loss of LKB1 (KL) in cells specifies aggressive oncological behaviour. Here we show that human KL cells and tumours share metabolomic signatures of perturbed nitrogen handling. KL cells express the urea cycle enzyme carbamoyl phosphate synthetase-1 (CPS1), which produces carbamoyl phosphate in the mitochondria from ammonia and bicarbonate, initiating nitrogen disposal...

REVIEW
Matthew W McCarthy, Ruta Petraitiene, Thomas J Walsh
Early diagnosis and prompt initiation of appropriate antimicrobial therapy are crucial steps in the management of patients with invasive fungal infections. However, the diagnosis of invasive mycoses remains a major challenge in clinical practice, because presenting symptoms may be subtle and non-invasive diagnostic assays often lack sensitivity and specificity. Diagnosis is often expressed on a scale of probability (proven, probable and possible) based on a constellation of imaging findings, microbiological tools and histopathology, as there is no stand-alone assay for diagnosis...

Here, we present a surface-enhanced Raman spectroscopy (SERS) nanosensor for environmental pollutants detection. This study was conducted on three polycyclic aromatic hydrocarbons (PAHs): benzo[a]pyrene (BaP), fluoranthene (FL), and naphthalene (NAP). SERS substrates were chemically functionalized using 4-dodecyl benzenediazonium-tetrafluoroborate and SERS analyses were conducted to detect the pollutants alone and in mixtures. Compounds were first measured in water-methanol (9:1 volume ratio) samples. Investigation on solutions containing concentrations ranging from 10(-6) g L(-1) to 10(-3) g L(-1) provided data to plot calibration curves and to determine the performance of the sensor...
