Resumen: En | Texto: En | PDF: En

Abstract The determination of hydroxymethylfurfural (HMF) in bee honey is performed by the spectrophotometric methods Winkler's and White's. The Winkler method reads the absorbances in the visible region of the spectrum, and the White method measures in the ultraviolet (UV) and visible regions of the spectrum. This study aims to compare the spectrophotometric methodologies of White and Winkler to the determination of HMF in bee honey. For the study, it was used a UV-visible spectrophotometer, 10 mm optical path quartz cuvettes, and ten bee honey samples of different flowering. Absorbances at 550 nm were analyzed by the Winkler method; absorbances at 284 nm and 336 nm in the White method; and a comparison of HMF concentration (mg/kg) was carried out between the methods. The results showed significant differences (p<0.05) in HMF concentration determined by both methods. The main conclusion is that the Winkler method presents higher HMF values than the White method.

Resumen: En | Texto: En | PDF: En

Abstract Background: Patients using immunosuppressive drugs may have unfavorable results after infections. However, there is a lack of information regarding COVID 19 in these patients, especially in patients with rheumatoid arthritis (RA). Therefore, the aim of this study was to evaluate the risk factors associated with COVID 19 hospitalizations in patients with RA. Methods: This multicenter, prospective cohort study is within the ReumaCoV Brazil registry and included 489 patients with RA. In this context, 269 patients who tested positive for COVID 19 were compared to 220 patients who tested negative for COVID 19 (control group). All patient data were collected from the Research Electronic Data Capture database. Results: The participants were predominantly female (90.6%) with a mean age of 53 ±12 years. Of the patients with COVID 19, 54 (20.1%) required hospitalization. After multiple adjustments, the final regression model showed that heart disease (OR =4.61, 95% CI 1.06–20.02. P < 0.001) and current use of glucocorticoids (OR =20.66, 95% CI 3.09–138. P < 0.002) were the risk factors associated with hospitalization. In addition, anosmia was associated with a lower chance of hospitalization (OR =0.26; 95% CI 0.10–0.67, P < 0.005). Conclusion: Our results demonstrated that heart disease and the use of glucocorticoids were associated with a higher number of hospital admissions for COVID 19 in patients with RA. Trial registration: Brazilian Registry of Clinical Trials RBR 33YTQC.

Resumen: En | Texto: En | PDF: En

OBJECTIVES: Ischemia and reperfusion (I/R) in the intestine could lead to severe endothelial injury, compromising intestinal motility. Reportedly, estradiol can control local and systemic inflammation induced by I/R injury. Thus, we investigated the effects of estradiol treatment on local repercussions in an intestinal I/R model. METHODS: Rats were subjected to ischemia via the occlusion of the superior mesenteric artery (45 min) followed by reperfusion (2h). Thirty minutes after ischemia induction (E30), 17β-estradiol (E2) was administered as a single dose (280 μg/kg, intravenous). Sham-operated animals were used as controls. RESULTS: I/R injury decreased intestinal motility and increased intestinal permeability, accompanied by reduced mesenteric endothelial nitric oxide synthase (eNOS) and endothelin (ET) protein expression. Additionally, the levels of serum injury markers and inflammatory mediators were elevated. Estradiol treatment improved intestinal motility, reduced intestinal permeability, and increased eNOS and ET expression. Levels of injury markers and inflammatory mediators were also reduced following estradiol treatment. CONCLUSION: Collectively, our findings indicate that estradiol treatment can modulate the deleterious intestinal effects of I/R injury. Thus, estradiol mediates the improvement in gut barrier functions and prevents intestinal dysfunction, which may reduce the systemic inflammatory response.

Resumen: En | Texto: En | PDF: En

Abstract This study aimed to evaluate the impact on digestibility and physical properties of enteral formulas by the addition of variable ingredients. Eight formulas were designed by a simplex-centroid evaluating different concentrations of inulin, medium-chain triglycerides (MCT) and whey protein isolate (WPI). Overall, the eight formulas developed presented mean values of 17.3% of protein, 62.3% of carbohydrates, 11.5% of lipids, a caloric value of 420 kcal/100 g, thus obtaining nutritionally adequate formulas. The emulsion stability of the suspended formulas was affected by all ingredients and the interactions between MCT – inulin, and MCT – WPI were effective in improving this parameter. Besides that, the use of inulin mostly affected the protein digestibility, according to the degree of hydrolysis and the peptide profile. The desirability function (d-value = 0.769) proposed a formulation containing 0.70% of inulin, 1.56% of MCT, and 1.73% of WPI. This proposed solution may improve enteral formulas because this has optimal emulsion stability and protein digestibility, which are essential characteristics for a product to be used by patients under special clinical conditions.

Resumo O sofrimento moral (SM) é vivenciado por uma pessoa e decorrente da contradição existente entre suas ações e convicções. O objetivo foi analisar o sofrimento moral vivenciado pelos profissionais de enfermagem que atuam no CAPS, bem como descrever e identificar os sentimentos decorrentes do SM e mecanismos de enfrentamento. Trata-se de uma pesquisa com abordagem qualitativa, na qual foi utilizado o método de Análise de Conteúdo de Bardin. Participaram da pesquisa sete profissionais de ambos os turnos de funcionamento do CAPS. Na análise temática de conteúdo das falas desses profissionais, emergiram quatro categorias: Ambiente, como fonte de sofrimento moral; Escassez de financiamento e improvisos; Sentimentos que emergiram das vivências de Sofrimento Moral; e Mecanismos de Enfrentamento dos profissionais. Neste estudo observou-se que os profissionais do CAPS Gentileza de Macapá vivenciam o SM em seu cotidiano, associado às questões do ambiente estrutural e insuficiência de recursos (humanos e materiais), que resultaram em sentimentos de impotência, desânimo, desmotivação e luta. Esse SM fez com que os profissionais pudessem construir mecanismos de enfrentamento, dentre eles o diálogo e o compartilhamento das angústias com a equipe.

Abstract Moral Distress (MD) is experienced by individuals from the contradiction existing between their actions and convictions. This study aimed to analyze the moral distress experienced by nursing professionals working at the CAPS and to describe and identify the feelings resulting from MD and coping mechanisms. This is a qualitative research that adopted the Bardin Content Analysis method. Seven Nursing professionals of both CAPS shifts participated in the research. Four categories emerged from the thematic analysis of the statements of these professionals, as follows: Environment as a source of moral distress; Shortage of funding and improvisations; Feelings that emerged from the experiences of Moral Distress and Coping Mechanisms of professionals. In this study, we observed that Macapá's Gentileza CAPS professionals experience MD in their daily life, associated with structural environment issues and insufficient (human and material) resources that resulted in feelings of helplessness, discouragement, demotivation, and struggle. This MD allowed these professionals to build coping mechanisms against moral distress, such as dialogue and sharing anguish with the team.

ABSTRACT Objective To describe the epidemiological and clinical profile of microcephaly cases in Recife, Pernambuco. Method This was a cross-sectional, quantitative study developed at a reference hospital for cases of microcephaly. Data were collected in August 2016 from the FormSUS system. All confirmed cases of microcephaly in the period from August 2015 to July 2016 were included, making up 180 cases. Data were analyzed using descriptive statistics and the chi-square and Fisher's exact tests. Results The majority of cases occurred in October and November 2015, with 55 (30.56%) and 52 (28.89%) cases, respectively. Serology for the Zika virus was reagent for 79 (43.89%) of the infants. The most prevalent symptom during gestation was exanthema 105 (57.3%). Furthermore, 150 (83.33%) of the children were born at full term, 78 (43.33%) presented percentiles between 10 and 50 in relation to weight and gestational age and 108 (60%) had -3 standard deviations in the comparison of head circumference with gestational age, thus considered to indicate severe microcephaly. Conclusions It is necessary to guarantee comprehensive and specialized care for these children. Epidemiological and entomological surveillance and more effective control actions in the fight against the vector are necessary.

Resumen: En | Texto: En | PDF: En

ABSTRACT Sour cassava starch (Polvilho azedo) is obtained from a spontaneous fermentation conducted by microorganisms from raw materials and fermentation tanks. This product is traditionally used in the baking industry for the manufacture of biscuits and Brazilian cheese breads. However, the end of fermentation is evaluated empirically, and the process occurs without standardization, which results in products of inconsistent quality. Predominant microbiota from a cassava flour manufacturer was isolated in order to select starter cultures for the production of sour cassava starch in a pilot-scale fermentation process. Lactic acid bacteria and yeasts were isolated, enumerated and grouped by Restriction Fragment Length Polymorphism, and PCR fingerprinting, respectively. One isolate of each molecular profile was identified by sequencing of the rRNA gene. LAB were prevalent throughout the entire process. Lactobacillus brevis (21.5%), which produced the highest values of acidity, and Lactobacillus plantarum (13.9%) were among the most frequent species. Pichia scutulata (52.2%) was the prevalent yeast and showed amylolytic activity. The aforementioned species were tested as single and mixed starter cultures in a pilot-scale fermentation process for 28 days. L. plantarum exhibited better performance as a starter culture, which suggests its potential for the production of sour cassava starch.

Resumen: En | Texto: En | PDF: En

ABSTRACT The objective of the current study was to evaluate the effects of three calcium:available phosphorus (Ca:aP) ratios and different supplementation with phytases from different origins on performance and ash, Ca, and P contents in the tibia of broilers. A total of 900 male broilers (22 to 35 days old) were fed ten dietary treatments in a completely randomized design. A 3 × 3 + 1 factorial scheme was used, corresponding to three Ca:aP ratios (4.5:1.0, 6.0:1.0, and 7.5:1.0) and three different supplementations with phytases from different origins (isolated or combined supplementation with bacterial and fungal phytase), plus a control diet. Regardless of the dietary Ca:aP ratio, the isolated use of bacterial phytase provided better feed conversion than the fungal phytase but did not differ from combined supplementation with bacterial and fungal phytase. However, regardless of the supplemented phytase, the 7.5:1.0 Ca:aP ratio decreased the feed conversion. Best results for bone P deposition were observed using diets containing the 4.5:1.0 Ca:aP and fungal phytase or the 4.5:1 and 6.0:1 Ca:aP ratios using the bacterial phytase. In general, when the parameters of feed conversion, bone ash, and P content in tibia are considered together, diets containing a 4.5:1.0 or 6.0:1.0 Ca:aP ratio and 1,500 FTU kg−1 bacterial phytase, or a 4.5:1.0 Ca:aP ratio using fungal phytase and only 1.0 g kg−1 available phosphorus provide better results.

O objetivo foi estabelecer um protocolo para indução de embriogênese somática em Anthurium andraeanum cv. Eidibel. O experimento foi arranjado em delineamento inteiramente casualizado, com esquema fatorial 5 x 5 x 5, cinco explantes (folha inteira e seccionada ao meio; pecíolo; segmento nodal e de raiz); cinco auxinas (AIA, ANA, AIB, 2,4-D e Picloram) em cinco concentrações (0,0; 2,5; 5,0; 7,5 e 10 µM) e cinco repetições, consistindo de cinco placas de Petri, mantidas em sala de crescimento a 25 ± 2 ºC, no escuro. Após 60 dias de cultivo, a maior produção de calos embriogênicos foi registrada nos segmentos nodais cultivados na presença de ANA (5; 7,5 e 10 µM), 2,4-D (10 µM) ou Picloram (7,5 e 10 µM). As análises histológicas confirmaram a presença de embriões com polaridade definida, procâmbio, meristema fundamental e protoderme em segmentos nodais cultivados em meio Pierik com 10 µM ANA. Depois da conversão dos embriões somáticos, as plantas foram aclimatizadas e transferidas para as condições in vivo, com crescimento normal das mesmas.

This study establishes a protocol for the induction of somatic embryogenesis in Anthurium andraeanum cv. Eidibel. The experiment was arranged in a completely randomized 5 x 5 x 5 factorial design using five explant types (whole leaves, half leaves; petiole; nodal segments and root segments) from in vitro plantlets; five auxins: indole-3-acetic acid (IAA), α-naphthaleneacetic acid (NAA), indole-3-butyric acid (IBA), 2,4-dichlorophenoxyacetic acid (2,4-D), and 4-amino-3,5,6-trichloropicolinic acid (Picloram); at five concentrations (0, 2.5, 5, 7.5 and 10 µM), with five replications using five Petri dishes. The cultures were maintained in a growth room at 25 ± 2ºC in the dark. The explant type was investigated for the induction of somatic embryogenesis in anthurium cv. Eidibel, and nodal segments were shown to be the most suitable explant for this process. After 60 days in culture, the highest number of embryogenic calli was recorded for the nodal segments cultured in NAA (5, 7.5 and 10 µM), 2,4-D (10 µM) and Picloram

The experiment was carried out to evaluate the influence of nutritional correction on the partial diet replacement or pure-food methodology to determine the energy values (apparent metabolizable energy - AME and nitrogen-correct apparent metabolizable energy - AMEn) and coefficient of metabolizability of nutrients of maize. The method of total excreta collection was used, with 120 female Cobb 500® broilers weighing 1,339±3 g and at 28 days of age distributed in a completely randomized design with five replicates and four birds per experimental unit. The treatments were pure maize with three levels of nutritional correction (0, 50 and 100%) and a maize-replaced basal diet (400 g/kg) with two levels of correction (0 and 100%). The corrections were made in order to meet the nutritional requirements of calcium, available phosphorus and sodium yonder trace minerals, vitamins, choline, lysine, methionine + cystine, threonine and tryptophan. The AME and AMEn of maize and coefficient of metabolizability of dry matter were higher when correction at 100% was made, regardless of the methodology used (pure feed or replaced basal diet). The correction at 50% of nutrients increased the coefficient of metabolizability of crude protein in pure maize when compared with 0 or 100% of correction. The values determined with pure maize were lower than those determined with the method of partial replacement. The absence of nutritional correction underestimates the energy values and metabolizability of nutrients from maize.
