title: Quality changes in reared, hot-smoked meagre (Argyrosomus regius Asso, 1801) during chill storage at 4 ± 1 °C

description: Abstract The aim of this study was to investigate quality and nutritional changes in reared meagre after the use of hot smoking technology. Hot smoking method was applied to the meagre and the resulting smoked fish were used to produce fillets, which were stored in refrigerator after being vacuum packed. As a result of chemical component analysis, it was seen that the fat content was low. In particular, the PUFA contents of meagre were found to be very high (35.53% Control). During storage, changes in fatty acid composition and the chemical, sensory and microbiological changes were analyzed. In terms of the chemical quality indicated, pH, TBA and TMA values didn’t exceed limit values during the storage of both fresh (6.25, 0.44 mgMDA/kg and 4.50 mg/100g) and hot smoked fish (6.23, 1.12 mgMDA/kg,5.57mg/100g respectively), but the TVB-N value exceeded limit values at day 56 of storage for hot smoked samples (39.50mg/100g). According to microbiological limit values accepted for seafood fresh and hot smoked meagre lost consumption characteristics after day 7 and day 35 of storage, respectively. Meagre was determined to be appropriate for the hot smoking process, based on the quality analyses, especially sensory analyses.

title: Hazards of Repeat Pregnancy during Adolescence: A Case-control Study

description: Abstract Objective To evaluate the social, obstetric and psychological risk factors related to repeat pregnancy in teenagers. Methods A case control study conducted at Centro de Atenção à Saúde Integral da Mulher (Caism, in the Portuguese acronym), in Campinas, Brazil, from 2015 to 2017. Three groups were selected: a case-group of adolescents who had repeat pregnancy and two control-groups, one consisting of adolescents who had delivered at first time and another one of adult women with more than one deliveries. Participants were asked about habits, socio-demographics characteristics, reproductive and obstetric history and assessed psychological issues. Results Ninety women were enrolled, 30 in each study group. Adolescents with repeat pregnancy have lower self-esteem scores and more ineffective contraceptive use. When compared with teens at first delivery, they had less schooling level (odds ratio [OR] 4.03 [1.37-11.8]), more school abandon (OR 8.16 [2.36-28.2]) and drugs use (OR 4.97[1.39-17.8]). Non-white skin color (OR 6.2 [1.15-41.0]), drugs use (OR 17.5 [2.62-116.6]) and first sexual intercourse under 15y (OR 18.0[2.82-115.0]) were found as higher risk factors for repeat pregnancy when comparing adolescents and adults.Moreover, adolescents withmore than one gestation had lower self-esteem and greater susceptibility to unplanned pregnancy. Conclusion There was an association between repeat pregnancy among adolescents and lower education, early onset of sexual activity, non-white skin color, low use of contraception and increased use of drugs.

title: Effect of different beta-glucan preparation pretreatments on fortified bread quality

description: Abstract This research explores the different beta-glucan preparation pretreatments prior to fortifying the bread (hydrating, freezing, boiling, blendering and their combination). Breads containing hydrated or dry beta-glucan preparations demonstrated lower values of specific volume than the control. On the other hand, the beta-glucan preparation, which was boiled or blendered after freezing showed higher specific volume. The firmest bread was achieved by adding beta-glucan preparation which was hydrated and blendered (significant at p ≤ 0.05) and the least firm was after application of a frozen blendered preparation. In our study, we researched the influence of pretreatment the beta-glucan preparation on the concentration of this compound. Our breads contain from 1.62 to 1.99 g beta-glucan/100 g of product. It seems that the best way of pretreatment is drying, freezing or boiling after freezing the beta-glucan preparation (significant at p ≤ 0.05). In general, the best performing method was boiling the beta-glucan preparation following dough addition.

title: Monitoring and risk assessment due to presence of heavy metals and pesticides in tea samples

description: Abstract Tea is one of the most consumed beverages after water, but unfortunately the application of pesticides and heavy metals in crops make it unsafe for use. This research was conducted to evaluate the risk of heavy metals and pesticides in samples of natural source tea (gardens) and different local market brands. High Performance Liquid Chromatography was used to detect pesticides, Bifenthrin, Lambda chalothrin, Imadachloroprid, Dichlorovas, Glyphosate and Emamectin. Heavy metals such as Zinc, Iron, Chromium, copper, manganese and cobalt were determined by atomic absorption spectroscopy. The value of HRI and THQ was still calculated for some exceeded samples. From results obtained some of the tea samples were contaminated from with heavy metals i.e., cobalt and manganese and pesticides as: dichlorovas, imacloroprid, bifenthrin, emamectin, glyphosate, difenaconazole and lambda above the allowed limits. The assessments revealed the potential for potential health risk for the consumers. The results of the study suggested that risk assessment and monitoring should be done at source that is at the production and processing area so that toxic effects are not passed on to the consumers or to the environment.

title: Acrylamide replaced by moringa extract in sugar production

description: Abstract This manuscript showed a new product that can be used in sugar and alcohol production to replace the acrylamide polymer, applied in the juice treatment. This new product is an organic extract obtained from moringa seeds, which present the flocculating protein 2S-Albumin. This biomolecule is added in the decanter together with the limed and heated juice, increasing the sedimentation speed of impurities that, if remain in the process, decrease the quality of the obtained sugar. This issue is of great importance because the acrylamide molecule has carcinogenic and neurotoxic action in humans and may be incorporated within the sugar crystal or the mud (filter-cake) used as a fertilizer. Furthermore, it should be noted that this manuscript presents the best technique to extract the S-Albumin protein from moringa seeds (using a CaCl2 solution 0.1 mol/L), the best dosage to apply in the sugarcane juice (1300 mg/L), and similary sugar quality achieved, compared with the process using the acrylamide polymer.

title: The effect of bioactive components of plant origin on the physicochemical and sensory characteristics of functional sausages

description: Abstract The aim of this study was to determine the effect of bioactive compounds of natural origin on the quality of sausages. Four variants of sausages were manufactured: a control variant (C) and three variants with the addition of catuaba, galangal, roseroot, maca, guarana and polyfloral honey (E1, E2, E3). The pH values, colour and chemical parameters (total phenolic content, total antioxidant activity and anti-inflamantory activity) of the meat batters and finished products were determined. Additionally, texture and sensory analyses of the sausages were performed. It was found that regardless of slightly lower acceptability, sausages with bioactive components were characterised by increased antioxidant properties, higher total phenol values and higher anti-inflamantory activity. The best results were obtained when the highest level of bioactive compounds was used (1.734% of catuaba bark, 0.022% of ground great galangal root, 0.458% of ground roseroot, 0.614% of maca root extract (4:1), 0.600% of ground guarana and 1.146% of polyfloral honey).

title: Non-invasive hair sampling of Neotropical otters

description: Abstract: Sampling wild animal populations using non-invasive techniques is advised when dealing with threatened species. Hair samples provide ecological information like species and individual identification. However, hair trapping is scarcely used in otters, due to their aquatic habits. Most studies are with captive individuals, so there is the need to test non-invasive hair trapping methods in otters in the wild. The aim of this study was to develop a simple and cost-effective method to collect hair from otter species in a non-invasive way. The study was carried out in the Paranapanema River, São Paulo State, Brazil, with the Neotropical otter (Lontra longicaudis Olfers, 1818), a protected species. Hair traps (wooden sticks and tree roots with adhesive tape or wax bands) were set during six nights on river banks, otter trails and scent-marking sites. Traps were baited with otter fresh spraints from other river locations. From the 23 traps, 10 (43.7%) were successful in collecting otter hairs, mostly guard-hair. The sticks were much more efficient than the roots at capturing otter hair (70.6.% vs. 0%) as well as adhesive tape when compared to wax (71.4% vs. 0%). Method simplicity and efficiency suggest that it can be a cost-effective way for collecting otter hairs without the need for capturing individuals. This method can be used for: assessment of local otter distribution; collecting otter hair samples for sex and individual identification (by molecular analysis), trophic ecology (by isotopic analyses), ecotoxicology (by contamination analysis) or behaviour ecology (by hormonal and stress levels analysis). More trapping campaigns should be implemented to further test the method's efficiency.

title: An approach to suicide among adolescents and youth in Brazil

description: Abstract This essay article examines suicide among young people in Brazil on the basis of Durkheim’s classical approaches as revisited in current discussions of social integration networks. It presents arguments regarding the behaviour of suicide mortality rates in the light of classical public health assumptions as to social causality in processes of health and illness. The mortality rates, updated in line with international statistics, review of data in Brazilian studies and recent series for Brazil, reveal suicide “aptitudes” by age, sex and social group. The linear and non-linear nature of the trends are treated in the context of pathways in complex social systems. Current data were prospected in the Ministry of Health’sNational Mortality Information System and World Health Organisation databases. In this policy analysis study, a conceptual outline was built up from classical theory updated to the present-day context, analysis of data relevant to the study object and observation of target groups for comprehensive, inclusive policies. The results of this analysis reveal that adolescents and young people are highly liable to growing, sustained, high-impact vulnerability to suicide.

title: Detection and sampling methods for isolation of Candidaspp. from oral cavities in diabetics and non-diabetics

description: The purpose of this study was to detect Candida spp. on the tongue and in the subgingival sites in healthy and type 2 diabetes (T2D) patients with chronic periodontitis (CP), and to compare the accuracy of sampling methods. This study included 131 patients divided into four groups: healthy control (group A), nondiabetics + CP (Group B), diabetics with good metabolic control + CP (group C) and diabetics with poor glycoregulation + CP (Group D). Cotton swab samples from tongue and subgingival samples were obtained from each patient with help of sterile paper points and a sterile curette. Swab cultures were made on Sabouraud dextrose agar. The number of CFUs was counted. The sampling methods for subgingival plaque were compared by Receiving Operator Curve (ROC). The presence of Candida spp. on the tongue was statistically significant among groups (group D vs. others three groups: χ2: p &lt; 0.005 for each group). Positive findings of subgingival Candida spp. did not differ among the groups. There were no significant differences in the quantification ofCandida spp., neither on the tongue, nor in the subgingival samples. 17.2% of diabetic patients revealed the presence ofCandida spp. in the subgingival samples, with negative finding on tongue. There was a significant difference in the sampling methods for subgingival plaque (p = 0.000). Candidaspp. is more prevalent on the tongue of diabetics. The sampling of subgingival plaque by a sterile curette is more accurate than with paper points. Subgingival plaque may represent a reservoir of commensals. It is necessary to standardize the sampling of subgingival plaque.

title: Effects of various irrigation/aspiration protocols on cleaning of flattened root canals

description: This study aimed to evaluate, by means of scanning electron microscopy (SEM), the cleaning of flattened root canals, varying irrigation/aspiration protocols during biomechanical preparation. Thirdy human mandibular incisors were distributed into three groups (n = 10) according to the aspiration/irrigation protocols: conventional, conventional + brush, and apical negative pressure irrigation. Irrigation procedure was performed with 5 mL of 1% NaOCl at each change of instrument; final irrigation was conducted with 17% EDTA for 5 min. After biomechanical preparation, the roots were sectioned and prepared for SEM analysis. The images obtained were evaluated under 35× and 1,000× magnification by three calibrated examiners, following a double-blind design. All data were analyzed using Kruskal–Wallis and Dunn’s post hoctests (α = 0.05). Canals wherein the conventional method and apical negative pressure irrigation were employed revealed less debris, statistically different from the conventional + brush group (p &lt; 0.05). Regarding the presence of smears, apical negative pressure irrigation was more effective in cleaning, showing lowest scores (p &lt; 0.05), compared with the other tested protocols. Comparing each root canal third revealed that the apical portion was difficult to clean as all the tested protocols showed similar high scores (p &gt; 0.05), both for the presence of debris and smear layer. In conclusion, although none of the studied irrigation/aspiration protocols have completely cleaned flattened root canals, apical negative pressure irrigation was more effective in smear layer removal, whereas the conventional + brush protocol was the least effective in removing the debris and smear layer.
