Abstract
OBJECTIVE The prevalence of food allergies (FA) has increased worldwide over the last few decades. Milk, eggs, and peanuts are among the most common allergens and can cause anaphylaxis. Therefore, we aimed to identify biomarkers that could predict the persistence and/or severity of IgE-mediated allergies to milk, eggs, and peanuts via a systematic review. METHODS This systematic review proceeded according to a protocol registered in the International Prospective Register of Systematic Reviews. Two independent authors extracted studies of interest from PubMed, SciELO, EMBASE, Scopus, and Ebsco databases and assessed their quality using the Newcastle-Ottawa Scale. RESULTS We selected 14 articles describing 1,398 patients. Among eight identified biomarkers, total IgE, specific IgE (sIgE), and IgG4 were the most often cited biomarkers of persistent allergies to milk, eggs, and peanuts. Skin prick tests, endpoint tests, and sIgE cutoff levels may predict positive responses to challenges with these foods. The basophil activation test is a biomarker for the severity and/or threshold of allergic reactions to milk and peanuts. CONCLUSION Only a few publications identified possible prognostic indicators of the persistence or severity of FA and outcomes of oral food challenges, indicating that more accessible biomarkers are needed to determine the likelihood of having a severe food allergic reaction.

Abstract
Background In 2001, Skakkebæk et al. proposed that certain male reproductive disorders might be grouped into a syndrome called testicular dysgenesis syndrome (TDS), as they all appear to be associated with disruption of the embryonic and foetal programming of gonadal development. TDS may be manifested in early life by the presence of genital malformations (hypospadias and cryptorchidism) and in adult life as disorders represented by low sperm counts and testicular cancer. Changes in androgen hormones during the foetal development, in addition to resulting in TDS, can also cause permanent changes in anopenile anogenital distance (AGDap) and anoscrotal anogenital distance (AGDas). Aims The objective of this study was to determine whether there is a relationship between late manifestations of TDS and reduced anogenital/anoscrotal distance. Materials and Methods The present study is a systematic review and meta-analysis. The research included papers from 2001 to 2020, comprising a total of 737 articles, and 13 articles were selected. Results Linear regression analysis was performed to evaluate the relationship between the two anogenital distance measures, which showed a significant positive association (P = 0.039). A meta-analysis was also performed and compared AGDap and AGDas between control and case groups, with cases defined as men with any late TDS manifestation. These data showed a significant reduction in AGDas in the affected population (P = 0.04), but no differences in the AGDap measure (P = 0.59). Conclusion Our study confirmed a significant relationship between reduced AGDas and late manifestations of TDS, providing further support to the association between prenatal androgen deficiency and late-onset reproductive disorders.

Abstract
C. brachyspora, a widespread dematiaceous fungus, was evaluated in this study to optimize the production of exopolysaccharides (CB-EPS). Optimization was performed using response surface methodology, and the best production yielded 75.05% of total sugar at pH 7.4, with 0.1% urea, after 197 h. The obtained CB-EPS showed typical signals of polysaccharides, which was confirmed by FT-IR and NMR. The HPSEC analysis indicated a polydisperse polymer, showing a non-uniform peak, with an average molar mass (Mw) of 24,470 g/mol. The major monosaccharide was glucose (63.9 Mol%), followed by mannose (19.7 Mol%), and galactose (16.4 Mol%). Methylation analysis encountered derivatives that indicated the presence of a β-d-glucan and a highly branched glucogalactomannan. CB-EPS was tested on murine macrophages to verify its immunoactivity, and the treated cells were able to produce TNF-α, IL-6, and IL-10. However, the cells did not produce superoxide anions or nitric oxide nor stimulated phagocytosis. The results demonstrated an indirect antimicrobial activity of macrophages by stimulating cytokines, showing another biotech applicability for the exopolysaccharides produced by C. brachyspora.

Abstract
INTRODUCTION This review aimed at investigating the impact of bundle components on the prevention of ventilator-associated pneumonia (VAP) in adults and the elderly. METHODOLOGY The databases consulted were PubMed, EBSCO, and Scielo. The terms Bundle and Pneumonia were searched in combination. The original articles were selected in Spanish and English; published between January 2008 and December 2017. After eliminating the duplicate papers, an analysis of the titles and the abstracts was performed in order to select the assessed articles. A total of 18 articles were included in this review that were evaluated according to the following criteria: research reference, country of data collection, type of study, characteristics of the studied patients, analysis and intervention performed, bundle items investigated and their results, and research outcome. RESULTS Four bundle items were presented in all the investigated papers. 61% of those works were considered from seven to eight bundle items. Daily evaluation of sedation interruption and daily assessment for verifying extubation condition, head-of-bed elevation at 30 degrees, cuff pressure monitoring, coagulation prophylaxis, and oral hygiene were the most reported bundle items. One study described the increased mortality of patients under mechanical ventilation when omitted the bundle items of oral hygiene and stress ulcer prophylaxis. Head-of-bed elevation at 30 degrees was the item reported in 100% of the studied papers. CONCLUSIONS Existing research demonstrated that VAP reduction occurred when bundle items were performed for adults and the elderly. Four works showed the relevance of team education as a central approach to the event reduction related to the ventilator.

Abstract
Liquidambar styraciflua L. is an aromatic species, popularly used in traditional Chinese medicine to treat diarrhea, dysentery, coughs, and skin sores. The present study was designed to investigate the chemical composition and biological potential of extracts obtained from the fruits of this plant. For the chemical evaluation, it was used mainly liquid and gas chromatography, plus NMR, and colorimetric methods. The aqueous extract (EA) originated two other fractions: an aqueous (P-EA) and an ethanolic (S-EA). The three extracts were composed of proteins, phenolic compounds, and carbohydrates in different proportions. The analyses showed that the polysaccharide extract (P-EA) contained pectic polysaccharides, such as acetylated and methyl esterified homogalacturonans together with arabinogalactan, while the fraction S-EA presented phenolic acids and terpenes such as gallic acid, protocathecuic acid, liquidambaric acid, combretastatin, and atractyloside A. EA, P-EA, and S-EA showed antioxidant activity, with IC50 values of 4.64 µg/mL, 16.45 µg/mL, and 3.67 µg/mL, respectively. The cytotoxicity followed the sequence S-EA > EA > P-EA, demonstrating that the toxic compounds were separated from the non-toxic ones by ethanol precipitation. While the fraction S-EA is very toxic to any cell line, the fraction P-EA is a promising candidate for studies against cancer due to its high toxicity to tumoral cells and low toxicity to normal cells.

Abstract
Introdução: Os trihalometanos (THM) constituem um grupo de subprodutos gerados pela desinfecção da água por meio da cloração. Desde a primeira vez em que foram reportados, em 1974, são alvos de estudos que buscam estabelecer uma relação positiva entre a exposição dos humanos a esses compostos e o desenvolvimento de câncer. Objetivo: Revisão da literatura cientifica disponível sobre a presença de THM na água e sua relação com o desenvolvimento do câncer de bexiga. Método: Levantamento bibliográfico da revisão feito nas bases de dados ScienceDirect e PubMeb. Os descritores utilizados foram ‘‘trihalomethane’’, ‘‘disinfection by-products’’ e ‘‘bladder cancer’’ dos Descritores em Ciências da Saúde (DeCS) da Biblioteca Virtual em Saúde. Os artigos selecionados foram publicados nos últimos cinco anos. Resultados: A amostra final desta revisão foi constituída por 31 artigos, sendo a maioria deles publicados em jornais e revistas sobre meio ambiente. Analisaram-se estudos descritivos, metanálises e outros estudos individuais com delineamento experimental, encontrando uma associação positiva, mas controversa, entre os THM e o câncer, associada a diferentes mecanismos. A relação mais consistente tem sido entre a exposição crônica e o câncer de bexiga. Conclusão: Os estudos reconhecem que existem riscos significativos a saúde relacionados aos THM, no entanto, evidencias que esclareçam os mecanismos de ação e o papel que outros fatores de risco possuem, juntamente com os THM, ainda permanecem incertas.

Abstract
AbstractParkin, a protein encoded by PRKN, discovered in the context of Parkinson’s disease, controls proteasomal degradation by protein ubiquitination and acts on cell cycle control and mitochondrial homeostasis, among other cellular processes. Parkin has been also implicated in several carcinomas, melanoma and leukemia. In the neoplastic setting, reduced parkin level usually indicates poorer prognosis. Some authors have described the associations between parkin and gliomas. Gliomas are a heterogeneous group of tumors that arise in the central nervous system, astrocytomas being the most common. The aim of this systematic review is to evaluate how parkin behaves in gliomas and the molecular pathways associated in this interaction. A search was conducted in PubMed, EBSCO and Scopus and 8 published articles were identified as eligible studies. The studies were categorized in three groups, according to their main emphasis: PRKN mutation patterns detected in gliomas, parkin effects on tumor growth and survival rates, and molecular interactions between parkin and other proteins. The studies showed higher PRKN mutation rates and lower parkin expression in high grade gliomas. Patients with higher parkin expression had better overall survival. Besides, different molecular pathways associated with parkin were described, some of them regarded as potential therapeutic targets.

Abstract
Liquidambar styraciflua L., ALTINGIACEAE, popularly known as sweet gum or alligator tree, is an aromatic tree with a natural distribution in North America and acclimated in Brazil. In traditional medicine, L. styraciflua L is used for the treatment of stomach disorders, wounds, and coughs. The present study was designed to investigate the biological potential and chemical profile of extracts obtained from aerial parts of L. styraciflua L. The chemical profile was established using liquid chromatography-mass spectrometry analysis and the extracts were tested for total phenolics, flavonoids, and tannins using spectrophotometric assays. The anti-inflammatory activity of L. styraciflua L was tested using an inhibition of hyaluronidase enzyme assay, and cytotoxic activities were tested by the 3-(4,5-dimethylthiazol-2 yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay. The synergy between the plant extracts with ciprofloxacin and tetracycline was studied by the checkerboard assay method against eight bacterial strains.The phytochemical investigation showed that the leaves and stem are rich in phenolics compounds (1419.34-1614.02 mg GAE/g, 875.21-1557.57 mg GAE/g, respectively), mainly flavonoids and hydrolyzable tannins. The samples of the stem exhibited the best anti-inflammatory activity. The butanol fraction of the stem was better than the commercial propolis extract. The hydroalcoholic extract of the stem and the propolis did not exhibit significant differences (p < 0.05) at any of the concentrations tested. A synergistic interaction was observed against the Gram-positive bacterial Enterococcus faecalis (hydroalcoholic extract of leaves and tetracycline) and Staphylococcus aureus (hydroalcoholic extract of stem and tetracycline). The IC50 values obtained for the extracts indicate the absence of toxicity and moderate cytotoxic for the hydroalcoholic extract of the stem. On the basis of our findings, L. styaciflua may be considered as a potential therapeutic source with high anti-inflammatory activity and synergistic interactions with antibiotics against bacteria.
