title: INTRAUTERINE GROWTH AND THE VITAMIN E STATUS OF FULL-TERM AND PRETERM NEWBORNS

description: ABSTRACT Objective: To determine the concentration of alpha-tocopherol in umbilical cord serum of full-term and preterm newborns, in order to assess the nutritional status of both groups in relation to the vitamin and its possible correlation with intrauterine growth. Methods: A cross-sectional observational study conducted with 140 newborns, of which 64 were preterm and 76 were full-term. They did not have any malformations, they came from healthy mothers, who were nonsmokers, and delivered a single baby. Intrauterine growth was evaluated by weight-to-gestational age at birth, using Intergrowth-21st. Thealpha-tocopherol levels of umbilical cord serum were analyzed by High Performance Liquid Chromatography. Results: The mean concentration of alpha-tocopherol in umbilical cord serum for preterm and full-term infants was 263.3±129.5 and 247.0±147.6 µg/dL (p=0.494). In the preterm group, 23% were small for gestational age, whereas in the full-term group, this percentage was only 7% (p=0.017). Low levels of vitamin E were found in 95.3% of preterm infants and 92.1% of full-term infants. There was no correlation between alpha-tocopherol levels and weight to gestational age Z score (p=0.951). Conclusions: No association was found between alpha-tocopherol levels and weight to gestational age at birth. Intrauterine growth restriction was more frequent in preterm infants and most infants had low levels of vitamin E at the time of delivery.

title: Study on immediate postoperative pain following cataract surgery: intraoperative endovenous administration of dipyrone

description: Abstract Objectives: Evaluate the effect of intraoperative endovenous administration of dipyrone on postoperative pain in patients submitted to phacoemulsification by correlating pain scores with duration of surgery and the amount of cumulative dissipated energy (CDE) delivered to the eye. Methods: The sample consisted of 104 eyes from 52 patients submitted to phacoemulsification under topic anesthesia and sedation. In each patient, one eye was treated intraoperatively with 1g dipyrone. Information was collected on cataract grade/type, duration of surgery and CDE. Postoperative pain was scored on a visual analog scale at 15 min and 24 hours. Results: Between 15 min and 24 hours, pain decreased significantly (p=0.004) among patients not treated with dipyrone, but no change was observed in patients receiving dipyrone. Caratact severity was positively associated with postoperative pain (p=0.046). Conclusion: The absence of a measurable effect of dipyrone on pain scores matched the literature. The decrease in pain scores at 24 hours among patients not treated with dipyrone may be explained by the influence of subjective psychological factors on pain perception. Higher grades of cataract were associated with greater postoperative pain.

title: CULTURAL ADAPTATION AND RELIABILITY ANALYSIS OF THE EARLY CLINICAL ASSESSMENT OF BALANCE

description: ABSTRACT Objective: To translate the Early Clinical Assessment of Balance (ECAB), an assessment scale developed specifically for children and adolescents with cerebral palsy into Brazilian Portuguese, evaluate semantic, idiomatic, experiential and conceptual equivalences, and to examine the face validity and the reliability within and between examiners of the Brazilian version. Methods: The following steps were done: translation by two independent translators; synthesis of translations; back translation into English; analysis of back-translations by a multidisciplinary committee and the author of the test to develop the final version of the test; test application training; administration of the translated version of ECAB (videotaped) in 60 children and adolescents with cerebral palsy; intra and inter-examiner reliability assessment. Reability was assessed by intraclass correlation coefficient (CCI). Results: The discrepancies found were related mainly to semantic equivalence and, therefore, there was no need to make cultural adaptations in any of the 13 items on the scale. The rate of agreement was greater than 90% and the reliability of the ECAB-Portuguese total score was excellent both for the intra-rater test (CCI=1.00) and for the inter-rater test (CCI=0.998). Likewise, the reliability evaluation of each of the scale items was also excellent. Conclusions: The translated version of the ECAB into Portuguese provides a tool for the evaluation of the specific balance for children and adolescents with cerebral palsy with different levels of functioning.

title: Evaluation of the clinicai analysis service provided to an emergency department

description: ABSTRACT Introduction: Time for releasing test results and critical value communication by the clinical laboratory are considered important determinants of patients' length of stay in the Emergency Department (ED). As well as physician satisfaction, they are used as quality indicators of the Clinical Analysis Service (CAS). Objective: The aim of this study was to evaluate the time to return a test result, the communication of critical values and the level of satisfaction of the ED physicians of a university hospital with the CAS. Material and methods: A physician satisfaction survey was conducted using a questionnaire. The test turnaround time for emergency requests was analyzed by observation of the pre-analytical phase and monitoring the analytical and post-analytical phases through the laboratory information system. In order to evaluate the communication of critical values by the CAS, a document analysis of the process was performed. Results: Physicians' overall satisfaction with the CAS was considered average. Greater satisfaction was observed with reliability of the results and the staff courtesy and lesser with the delivery time of results. The test turnaround time exceeded clinicians' expectations and the average described in the literature. No experience with critical-value communication was perceived. Conclusion: The results show several opportunities for progress in the relationship between ED and CAS. The improvement of laboratory quality indicators also depends on the involvement of ED physicians and nurses and embraces monitoring, planning, education and investment in system computerization.

title: Ophthalmologic manifestations of elderly patients with human immunodeficiency virus infection

description: Abstract Objectives: Identify and describe ocular changes in elderly with HIV or aids through ophthalmological examination. Evaluate the association between ocular alterations and the level of TCD4 lymphocytes, time of antiretroviral therapy, demographic characteristics and age range. Methods: Case series of 40 elderly patients with HIV infection. The study was carried out at the ophthalmology and immunology outpatient clinics of the Gaffrée and Guinle University Hospital (HUGG) from january 2017 to june 2018. The patients were attended at the ophthalmology clinic and underwent a ophthalmological exam including: anamnesis, visual acuity, ocular motility, pupillary reflex, biomicroscopy, aplanation tonometry and fundoscopy. Statistical analyses were performed using SPSS 20.0. Results: The average of the 40 patients was 64.7 years (sd: 5.1), aged between 60 and 78 years, and the average time of HIV infection was 16.6 years (sd: 7 years). Most of the patients examined had normal vision (55%) and normal intraocular pressure (between 11 and 21 mmHg). The main complaints of patients during anamnesis were visual blurring (50%), visual acuity reduction (47.5%), ocular itchiness (27.5%), tearing (25%) and burning (25%).The most frequent changes in biomicroscopy were: cataract (92.5%) and dry eye (32.5%). Funduscopy found 43.8% of retinal vascularization alterations, 43.8% of alterations related to the optic nerve and 31.3% related to retinal posterior pole. Conclusion: Ocular changes were common and can be explained by senility, inflamatory changes caused by chronic HIV infection, adverse effects of antiretroviral therapy and early biological ageing associated to HIV infection.

title: Deterioration of Teak Wood in Accelerated Decay Test

description: ABSTRACT The present study aimed to evaluate the biological resistance of teak (Tectona grandis) heartwood and sapwood to the action of Trametes versicolor and Gloeophyllum trabeum fungi in laboratory accelerated decay assays. The mass loss evaluation of the samples was performed periodically. The heartwood presented a higher percentage of extractives and the sapwood of holocelluloses. The sapwood and heartwood subjected to the fungus Gloephyllum trabeum remained stable. For the Trametes versicolor fungus, there was an increasing loss of mass over time for both regions, presenting a mass loss of 40% for the sapwood and of 20% for the heartwood at the conclusion of the assay. Teak wood was classified as highly resistant to the fungus Gloeophyllum trabeum, and moderately resistant to Trametes versicolor.

title: Economic and Financial Analysis of Tree Seedling Production Using Composted Biosolids Substrate

description: ABSTRACT The aim of this study was to evaluate production profitability of Croton urucurana and Cytharexyllum myrianthum seedlings produced in substrates composed of mixtures of composted biosolids and carbonized rice husk in different concentrations of nutrient solution. Seedlings were subjected to three doses of fertigation solutions. In order to check quality standards which indicated production cycle, the height, stem diameter and root quality were evaluated. Economic viability was determined by indicators of economic attractiveness commonly used for investment projects. Production costs of seedlings varied according to the production cycle, substrate compositions and nutritional management. The substrate with higher volume of composted biosolids and lower concentrated fertilizer was the one with the highest profitability and the lowest production cost.

title: Enzyme-assisted extraction of polyphenols from green yerba mate

description: Abstract The enzyme-assisted extraction of bioactive compounds from plants has been studied as an alternative green technology and the carbohydrases have been candidates to improve the extraction process of numerous such compounds from plants. Polyphenols are secondary plant metabolites, generally involved in the defense against different types of stress and yerba mate (Ilex paraguariensis A. St.-Hil., Aquifoliaceae) is a natural source of these antioxidant compounds. The aim of this work was to evaluate the enzyme-assisted extraction of polyphenols from green yerba mate employing response surface methodology (RSM), in order to determine the best extraction conditions. The independent variables were temperature (33.2 to 66.8 °C), enzyme concentration (0 to 336 FGBU/100g), reaction time (19 to 221 minutes) and pH (2.82 to 6.18). The use of carbohydrases increased the extraction of polyphenols from about 38.67% to 52.08%. The present results showed that all the independent variables were significant at the linear level and that temperature and pH were not significant at the quadratic level. The interactions of temperature and pH; enzyme and reaction time; and enzyme and pH were significant. The regression model presented a determination coefficient (R2) close to 0.85 and a fitted value close to 0.45. Considering the results of this study and their industrial viability, the best conditions for the extraction of polyphenols from green yerba mate are a temperature of 50.0 °C, enzyme concentration of 168 FGB/100 g, reaction time of 120 minutes and pH value of 4.50. This study was the first RSM-based report of the optimization of the enzyme-assisted extraction of total phenolic compounds from green yerba mate.

title: Comparative evaluation of the quality of Papanicolaou staining at different intervals of fixation times using 96% ethyl alcohol

description: ABSTRACT Introduction: Fixation of cytological smears consists of immediate immersion in appropriate fixative, in order to preserve cellular morphological characteristics, it is essential for the microscopic examination and diagnostic interpretation. Objective: To evaluate the influence of fixation times on the morphological and staining characteristics of samples fixed in ethanol and stained by the Papanicolaou method. Method: Experimental, quantitative and qualitative research was carried out on 99 samples of the jugal mucosa scrapings from 33 participants, fixed in 96% ethyl alcohol in three different times. Group A: 15 minutes; group B: 30 minutes; group C: seven days. The quality of staining was categorized in Optimal, Good, Regular and Poor, with subsequent recategorization at optimal and non-optimal. To verify the association among the groups and the categories, Fisher’s exact test was performed, with significance level of 0.05. Results: From the 99 stained slides, 19 were discarded due to acellularity, remaining 80 slides. From these, 28 in group A, 26 in group B and 26 in group C were evaluated. In Group A, optimal quality was found in 60.7% (n = 17), good in 28.6% (n = 8), regular in 10.7% (n = 3) and poor in 0% (n = 0). In group B optimal was found in 61.5% (n = 16), good in 30.8% (n = 8), regular in 7.7% (n = 2) and poor in 0% (n = 0). In group C, optimal was found in 92.3% (n = 24), good in 7.7% (n = 2), regular in 0% (n = 0) and poor in 0% (n = 0). In the three groups, there was no representation of the Poor category. Conclusion: The results suggest that there is a significant difference in the staining quality (p-value = 0.01) according to the fixation time.
