title: Epidemiological overview of HIV/AIDS in pregnant women from a state of northeastern Brazil

description: ABSTRACT Objective: To learn the epidemiological characteristics of HIV infection in pregnant women. Method: Descriptive study with quantitative approach. The study population was composed of pregnant women with HIV/AIDS residing in the state of Alagoas. Data were organized into variables and analyzed according to the measures of dispersion parameter relevant to the arithmetic mean and standard deviation (X ± S). Results: Between 2007 and 2015, 773 cases of HIV/AIDS were recorded in pregnant women in Alagoas. The studied variables identified that most of these pregnant women were young, had low levels of education and faced socioeconomic vulnerability. Conclusion: It is necessary to include actions aimed at increasing the attention paid to women, once the assurance of full care and early diagnosis of HIV are important strategies to promote adequate treatment adherence and reduce the vertical transmission.

title: ELECTROCOAGULATION-FLOTATION PROCESS: INVESTIGATION OF OPERATIONAL PARAMETERS FOR WASTEWATER TREATMENT FROM FISHERY INDUSTRY

description: The objective of this study was the utilization of an electrocoagulation-flotation process to evaluate the treatment of a real wastewater from fish industries (Brazil - SC). This type of effluent is usually treated by conventional processes, which are often not sufficient to meet the desired final quality of legal environmental requirements. The effect of current density, pH and treatment time was evaluated. The best experimental conditions for the process were current of 5 A, potential of 15 V and distance between electrodes equal to 10 mm. Under these conditions, the removal of the contaminants were expressive for all analyzed parameters as follows: average color reduction of 95.5%; turbidity of 96.9%; COD 93.3; BOD5 of 97.5%; phosphorus of 88.5% and oils and greases of 93.6%.

title: In vitro effects of alcohol-containing mouthwashes on human enamel and restorative materials

description: Abstract The objective of this study was to evaluate the in vitro effects, including surface morphological characteristics and chemical elemental properties, of different mouthwash formulations on enamel and dental restorative materials, simulating up to 6 months of daily use. Human enamel samples, hydroxyapatite, composite resin, and ceramic surfaces were exposed to 3 different mouthwashes according to label directions — Listerine® Cool Mint®, Listerine® Total Care, and Listerine® Whitening — versus control (hydroalcohol solution) to simulate daily use for up to 6 months. The samples were analyzed using scanning electron microscopy (SEM), infrared spectrophotometry (µ-Fourier transform infrared microscopy), energy-dispersive X-ray (EDX) spectroscopy, and color analysis before and after exposure. No relevant changes were observed in the morphological characteristics of the surfaces using SEM techniques. The physical and chemical aspects of the enamel surfaces were evaluated using mid-infrared spectroscopy, and EDX fluorescence was used to evaluate the elemental aspects of each surface. There was no variation in the relative concentrations of calcium and phosphorus in enamel, silicon and barium in composite resin, and silicon and aluminum in the ceramic material before and after treatment. No relevant changes were detected in the biochemical and color properties of any specimen, except with Listerine® Whitening mouthwash, which demonstrated a whitening effect on enamel surfaces. Long-term exposure to low pH, alcohol-containing, and peroxide-containing mouthwash formulations caused no ultra-structural or chemical elemental changes in human enamel or dental restorative materials in vitro.

title: Nitrile rubber and carboxylated nitrile rubber resistance to soybean biodiesel

description: Abstract Biodiesel has been considered a suitable substitute for petroleum diesel, but their chemical composition differs greatly. For this reason, biodiesel interacts differently than petroleum diesel with various materials, including rubbers. Therefore, the resistance of some elastomers should be thoroughly evaluated, specifically those which are commonly used in automotive industry. Nitrile rubber (NBR) is widely used to produce vehicular parts that are constantly in contact with fuels. This paper aimed to assess the resistance of carboxylated nitrile rubber (XNBR) with 28% of acrylonitrile content to soybean biodiesel in comparison with non-carboxylated nitrile rubber samples, with high and medium acrylonitrile content (33 and 45%). NBR with medium acrylonitrile content showed little resistance to biodiesel. However, carboxylated nitrile rubber even with low acrylonitrile content had similar performance to NBR with high acrylonitrile content.

title: Proposal for a structured computed tomography report in the evaluation of pancreatic neoplasms based on expert opinions

description: Abstract Objective: To create a structured computed tomography (CT) report for the systematic evaluation of pancreatic ductal adenocarcinoma (PDAC), based on the opinions of clinicians and surgeons. Materials and Methods: This was a prospective study in which we applied a 21-item questionnaire to experts in pancreatic diseases in order to create a model of a structured abdominal CT report. The questionnaire addressed the location and size of PDACs, as well as their effects on adjacent structures and on the vasculature, together with metastases. We used a Likert scale to determine which of those parameters should be included in the model. Results: A total of 18 experts (12 surgeons and 6 clinicians) from 9 institutions completed the questionnaire. All of the experts agreed that the following (if present) should be described in the CT report on a PDAC: the degree of enhancement; the diameter and location of the lesion; pancreatic duct obstruction; biliary dilatation; pancreatic atrophy; liver metastases; peritoneal nodules; ascites; lymph node enlargement; and invasion of adjacent structures. More than 80% of the experts agreed that the report should also describe the relationship between the PDAC and the surrounding vasculature. Conclusion: We have developed a template for a CT report on patients with PDAC, based on the opinions of experts involved in the treatment of such patients.

title: Heart Transplantation for Peripartum Cardiomyopathy: A Single-Center Experience

description: Abstract Background: Peripartum cardiomyopathy is an idiopathic disorder defined by the occurrence of acute heart failure during late pregnancy or post-partum period in the absence of any other definable cause. Its clinical course is variable and severe cases might require heart transplantation. Objective: To investigate long-term outcomes after heart transplantation (HT) for peripartum cardiomyopathy (PPCM). Methods: Out of a single-center series of 1938 HT, 14 HT were performed for PPCM. We evaluated clinical characteristics, transplant-related complications, and long-term outcomes, in comparison with 28 sex-matched controls. Primary endpoint was death from any cause; secondary endpoints were transplant-related complications (rejection, infection, cardiac allograft vasculopathy). A value of p &lt; 0.05 was considered of statistical significance. Results: PPCM patients and matched controls were comparable for most variables (all p values &gt; 0.05), except for a higher use of inotropes at the time of HT in PPCM group (p = 0.03). During a median follow-up of 7.7 years, 16 patients died, 3 (21.5%) in PPCM group and 13 (46.5%) in control group. Mortality was significantly lower in PPCM group (p = 0.03). No significant difference was found in terms of transplant-related complications (p &gt; 0.05). Conclusions: Long-term outcomes following HT for PPCM are favorable. Heart transplantation is a valuable option for PPCM patients who did not recover significantly under medical treatment.

title: Hand hygiene management among nurses: collective health challenges

description: ABSTRACT Objective: To describe the determining factors in hand hygiene management among nurses and identify associated collective health challenges. Method: Cross-sectional descriptive study. Data were collected using a questionnaire that was applied in four internal medicine units of a hospital of reference in Portugal. Results: The sample was composed of 50 nurses aged 26 to 55 years (mean age of 34.88 years); 80% were women, 58% had a Bachelor’s degree, and had 5-30 years of nursing practice (X̄ =11.94;±5.92). The vast majority of nurses (90%) reported complying with the existing recommendations on hand hygiene in pre-established moments. However, none of the nurses were able to identify all the moments for hand hygiene using water and soap or alcohol-based handrub. Conclusion: This study shows that continuous training, adequate materials/structures in the units, and redesigned administration/supervision practices are determining factors to achieve higher levels of adherence to hand hygiene among nurses, as well as increased quality and safety in care delivery, which is a current collective health challenge.

title: Thyrotropin and free thyroxine levels and coronary artery disease: cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

description: Data on the association between subclinical thyroid dysfunction and coronary artery disease (CAD) is scarce. We aimed to analyze the association between thyroid function and CAD using baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). We included subjects with normal thyroid function (0.4-4.0 mIU/L, and normal free thyroxine, FT4, or 0.8 to 1.9 ng/dL), subclinical hypothyroidism (SCHypo; TSH&gt;4.0 mIU/L and normal FT4), and subclinical hyperthyroidism (SCHyper; TSH&lt;0.4 mIU/L and normal FT4) evaluated by coronary computed tomography angiography. We excluded individuals using medications that interfere in thyroid function or with past medical history of cardiovascular disease. Logistic regression models evaluated the presence of CAD, segment involvement score (SIS) &gt;4, and segment severity score (SSS) &gt;4 of coronary arteries as the dependent variables, and quintiles of TSH and FT4 as the independent variables, adjusted for demographical data and cardiovascular risk factors. We included 767 subjects, median age 58 years (IQR=55-63), 378 (49.3%) women, 697 euthyroid (90.9%), 57 (7.4%) with SCHypo, and 13 (1.7%) with SCHyper. No association between TSH and FT4 quintiles and CAD prevalence was noted. Similarly, no association between TSH levels and the extent or severity of CAD, represented by SIS&gt;4 and SSS&gt;4 were seen. Restricting analysis to euthyroid subjects did not alter the results. TSH levels were not significantly associated with the presence, extent, or severity of CAD in a middle-aged healthy population.

title: Vaso-occlusive retinopathy by systemic lupus erythematosus associated with the antiphospholipid antibody syndrome

description: Abstract To report the case of a patient with vaso-occlusive retinopathy due to systemic lupus erythematosus (SLE) associated with antiphospholipid antibody syndrome (APAS), which started with signs and symptoms of autoimune hemolytic anemia accompanied by sudden monocular visual loss. Few cases of SLE manifestation primarily involving ocular changes have been reported in the Brazilian and international literature. Screening for antiphospholipid antibodies is of the greatest importance for patients with lupus retinopathy, so that immediate therapy with anticoagulants may be instituted in order to prevent vascular thrombosis, which worsens the visual prognosis.
