title: Improvement of Polypropylene Adhesion by Kraft Lignin Incorporation

description: Low surface energy and poor adhesion are well-known characteristics of polypropylene (PP). Surface treatments such as plasma, corona, and laser are usually applied to overcome these limitations. However, current studies highlight the incorporation of hydrophilic or amphiphilic polymers into hydrophobic low-surface-energy polymers as an alternative for increasing surface energy and thus improving adhesion. Lignin could be a promising amphiphilic polymer for use in increasing surface energy. In this work, PP/kraft lignin composites were obtained by incorporating up to 5 wt% of kraft lignin (KL) into a PP matrix. Corona treatment was applied to pristine PP and composites surfaces. Contact angle measurements and peeling tests were carried out to investigate the effects of KL incorporation and corona treatment on the surface energy and the mechanical strength of adhesion. Differential scanning calorimetry (DSC) was used to evaluate the PP’s crystallinity index and recrystallization temperature and to dismiss their effects on the surface energy changes. Scanning electron microscopy (SEM) was applied to investigate the lignin dispersion. The results show that KL incorporation has potential as a method to improve the surface energy of PP, improve its poor adhesion, and enhance the effects of corona treatment.

title: Mortality by suicide in the Brazilian population, 1996-2015: what’s the predominant trend?

description: Abstract Background Suicide is one of the three most common causes of death worldwide and varies according to sex and age. Objective to analyze the trend of suicide mortality in the Brazilian regions from 1996 to 2015, and its association with sex and age. Method Ecological study of a time series using the suicide deaths analyzed by regions from 1996 to 2015, contained in the Mortality Information System. We used Prais-Winsten regression model to evaluate the trend of suicide mortality; and chi-square to compare the percentages of mortality by sex and age. Results There was a growing trend of deaths by suicide in the North (1.73%, Coef = 0.007, p-value &lt;0.001), Northeast (2.30%, Coef = 0.010, p-value = 0.006) and Southeast (1.41%, Coef = 0.006, p-value &lt;0.001) and decreasing in the South (-0.57%, Coef = -0.002, p-value = 0.001). Prevalence of men in the percentage of deaths (p &lt;0.001). Conclusion Suicide is considered an important public health problem, requiring actions to disseminate risk and prevention programs.

title: CHEMICAL COMPOSITION, ANTIRADICALAR AND ANTIMICROBIAL ACTIVITY OF FABACEAE POLLEN BEE

description: The aim of this investigation was to analyze two samples of pollen collected by Apis mellifera bees in view of their chemical composition, antiradicalar and antimicrobial activities. Palynological analysis showed that the predominant pollen was Fabaceae species (42.3%, sample I and 50.6%, sample II). The characterization by ultra-performance liquid chromatography coupled with a diode array detector and quadrupole time of flight mass spectrometry (UPLC-DAD-QTOF-MS/MS) resulted in the identification of three derivatives of putrescine (di-4-coumaroylputrescine, coumaroyl-feruloyl-putrescine and di-feruloyl-putrescine), two spermidine derivatives (coumaroyl-di-cafeoyl-spermidine and tri-coumaroyl-spermidine and four biflavonoids (2,3-di-hydrohydroxy-amentoflavone, 2,3-dihydro-amentoflavone, amentoflavone and 2,3-dihydro-biapigenin). The two samples showed antiradical and antimicrobial activities, probably due to the presence of these compounds.

title: CORRELATION BETWEEN LUMBAR SPINAL STENOSIS BASED ON MORPHOLOGY OF THE DURAL SAC AND THE QUALITY OF LIFE

description: ABSTRACT Objective: To evaluate the possible existence of a significant correlation between quality of life and severity classification of lumbar stenosis based on dural sac morphology in outpatients. Methods: Forty patients with a diagnosis of lumbar stenosis followed at a university hospital were submitted to magnetic resonance imaging (MRI) and quality of life questionnaires: Oswestry Disability Index (ODI), SF-36, Swiss Spinal Stenosis Questionnaire (SSS) and EQ-5D. They were classified as type A, B, C or D based on MRI. For the statistical analysis, the Spearman correlation was used. Results: Seventeen female patients and 23 male patients with mean age of 56.5 years constituted the sample. ODI had a mean dysfunction of 44.9%, the PCS score averaged 29.9, the MCS score was 41.3. The general symptoms of SSS presented a mean of 3.2 and the EQ-5D presented an average of 0.491. The patients with the highest severity in the classification were not necessarily those who presented worse scores in the quality of life questionnaires. Conclusion: The classification of severity of the lumbar spinal stenosis based on dural sac morphology does not correlate with the applied quality of life questionnaires. Level of Evidence III; Cross-sectional observational study.

title: Effect of Harpin protein as an elicitor on the content of phenolic compounds and antioxidant capacity in two hydroponically grown lettuce (Lactuca sativa L.) varieties.

description: Abstract Harpin protein was used as an elicitor in green (butterhead) and red (oak leaf type) varieties of hydroponically grown lettuce (Lactuca sativa L.). Its impact on polyphenolic content and antioxidant capacity was evaluated. Harpin protein was sprayed three days before harvesting in concentrations of 45, 60, and 120 mg/L. Green lettuce samples showed a positive response to Harpin by significantly increasing its phenolic content from 12 (control) to 16.43 mg gallic acid equivalents (GAE)/100 g dry weight (DW) (120 mg/L Harpin treatment) which means a 36.9% increase. Chlorogenic acid was the only phenolic compound that increased its concentration after lettuce induction with Harpin treatment. Antioxidant capacity, evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH˙) and ferric reducing antioxidant power (FRAP) methods, also showed a significant increase (46.5 and 64.3%, respectively) in Harpin-treated green lettuce. The red lettuce variety showed none or a negative response to Harpin treatment for all parameters evaluated. These results show that elicitation may be an effective strategy to enhance phenolic content in lettuce varieties.

title: Evaluation of the effectiveness of a local exhaust ventilation system employed for controlling crystalline silica in a silicone rubber industry

description: Abstract Introduction: local exhaust ventilation (LEV) systems can be used for controlling chemical occupational exposure. However, sometimes they are improperly designed, installed or operated, becaming ineffective. Objective: to evaluate the effectiveness of a LEV used for controlling crystalline silica employed in the production of silicone rubber. Methodology: the assessment carried out was based on technical procedures described in the industrial ventilation reference literature and was systematized in three steps - initial inspection, evaluation of LEV parameters and environmental assessment. A field test was applied in a LEV installed in a silica and silicone mixer of a rubber manufacturing company located in the state of São Paulo, Brazil. Results: the inspection and evaluation steps of the LEV parameters pointed out deficiencies in the design, operation and maintenance of the system, testified by its reduced capture velocity. Regarding the environmental assessment, concentrations of crystalline silica above the reference value were found in the respirable fraction. Conclusion: the study confirmed that, for the LEV effective functioning, their design, installation, operation and maintenance have to be in conformity with the principles of ventilation engineering.

title: Road freight transport: fatal work accidents and labor inspection

description: Abstract Introduction: a large number of fatal work accidents (FWA) occurs in road freight transport (RFT). Drivers’ excessive working hours and inadequate rest are highlighted among the main contributing factors. In Brazil, the Ministry of Labor is the federal authority responsible for inspecting such working conditions. Objectives: to evaluate whether the labor inspection of the RFT sector received attention that was proportional to the magnitude of its fatal occupational injuries indicators and to analyze the verification of drivers’ working and rest hours in the inspections. Methods: quantitative, descriptive and exploratory study using documentary and bibliographical information, and official data of FWA and Federal Labor Inspection from 2008 to 2012. Results: among the 20 activities/occupations with more fatal accidents, the RFT (1430 deaths; 37.97 deaths/ 100,000 employed persons) and the long-distance truck driver occupation (1098 deaths; 55.33 deaths/100,000 employed persons, in 2011) were highlighted. However, the labor inspections carried out in the RTF sector represented 1.4% of the total number of the Federal Labor inspections, and the drivers’ working and rest hours were checked only in half of these actions. Conclusion: it is necessary to increase the number of inspections in the RFT sector whilst the factors that contribute to truck drivers’ FWA must be checked.

title: PREVALENCE OF EARLY SPINAL DEFORMITY IN CHILDREN WITH GMFCS V CEREBRAL PALSY

description: ABSTRACT Objective: Spastic cerebral palsy (sCP) is a cause of early onset scoliosis, although there are no data on its prevalence. Our objective was to determine the prevalence of early onset neuromuscular spinal deformities (SD) in severely compromised children with sCP. Methods: Cross-sectional quantitative, observational, exploratory, and descriptive study. Review of clinical records. Inclusion criteria: age 2 to 5 years, sCP, level V of the GMFCS, residents in our province. X-ray blind reading by 2 observers. The Student t test was used for parametric data and the chi-square test for non-parametric data. Level of statistical significance: p &lt; 0.05. Results: Thirty-eight cases of 158 registered were included. Average age: 3 years 7 months (2 years – 5 years 2 months). Sex: 21 male/17 female. The predominant etiologies were perinatal: 21 (55.3%), and the prevalent nutritional status was eutrophic: 28 cases (73.7%). SD was very frequent: 32 patients (84.2%) without statistical differences between sexes; there were 20 kyphoscoliosis, 1 lordoscoliosis, 6 scoliosis, 5 hyperkyphosis. Mean angular values: 23.9° (10°- 50°) for the frontal plane deformities and 58° (9°- 92º) for the sagittal deformities. Seventeen patients (44.7%) had average pelvic obliquity of 15° (2°- 30°) without differences in patients with and without SD. There was no association between SD and etiology, digestive disorders, seizures, nutritional status, hip excentration, or limb deformities. Conclusions: The prevalence of SD in children up to 5 years old with severe sCP is high: 84.2% (32/38 cases). The orthopedic profile is children with sCP of any etiology at GMFCS level V, with multiple disabilities and independently of associated limb deformities. Level of evidence I; Diagnostic Studies - Investigating a Diagnostic Test: Testing of previously developed diagnostic criteria on consecutive patients (with universally applied reference “gold” standard).

title: Effectiveness of monthly and fortnightly anti-VEGF treatments for age-related macular degeneration

description: ABSTRACT Purpose: To study the efficacy and safety of treatments with ranibizumab and bevacizumab for exudative age-related macular degeneration. Methods: A parallel randomized clinical trial was conducted to compare the efficacy and safety of three regimens (bevacizumab every month, bevacizumab every 2 weeks, and ranibizumab every month), followed by as-needed retreatments, for 1 year, in previously untreated individuals with age-related macular degeneration. The primary outcome was change in visual acuity and in central macular thickness after 1 year of follow-up. Subjects were assigned randomly to one of the three groups in a 1:1:1 ratio, and investigators and examiners were blinded to the randomization results. Results: We included 15 patients in each group. After 1 year of follow-up, we found statistically significant improvements in visual acuity and central macular thickness reduction in all groups. However, we found no statistically significant differences between the three groups. Conclusions: The bi-weekly follow-up was effective and we found no significant differences in efficacy or safety between the treatments with ranibizumab and bevacizumab.
