ABSTRACT

Constant fishing industry innovations in response to consumer demands for novel, balanced healthy products exhibiting high nutritional value, as well as easy to prepare and ready to consume, have led to the emergence of new technologies. Among them, the development of products based on ground beef and fish mixtures are noteworthy. In this context, the purpose of this study was to develop products from different ground rainbow trout and tilapia fillet ratios, in the form of meatballs and nuggets, determining their proximate composition and physico-chemical, microbiological and toxicological characteristics. The average dry matter percentage of the developed products was 29.20±2.30%, while mineral content was 1.45±0.55%, lipid pulp content, 3.70±0.30% and crude pulp protein, 16.60±2.04%. Total psychotropic counts remained below 102 CFU/g, for standard counting on aerobic microorganism plates. Histamine and sulfur-based compounds were not detected in any of the prepared samples. The purpose of the work proposal was to develop foods and technologies that can serve as standards, allowing for simple handling products that apply ground meat mixtures from different fish species to maintain adequate nutritional indices after processing.(AU)


A constante inovação da indústria pesqueira, em resposta às demandas dos consumidores por novos produtos saudáveis, com alto valor nutritivo, balanceados, de fácil preparo e prontos para consumo, levou ao surgimento de novas tecnologias, entre elas o desenvolvimento de produtos à base de mistura de carne moída de pescado. Nesse contexto, a proposta deste trabalho é desenvolver produtos a partir de carne moída de pescado de truta-arco-íris e tilápia, confeccionando almôndegas e nuggets em diferentes proporções, com determinação da composição centesimal e de suas características físico-químicas, microbiológicas e toxicológicas. A matéria seca percentual média foi de 29,20±2,30%. Teores de matéria mineral nos produtos estão em 1,45±0,55%. Os teores de lipídeos aferidos na polpa foram de 3,70±0,30%, e os níveis de proteína bruta apresentados na polpa de 16,60±2,04%. A contagem de psicrotróficos totais manteve-se abaixo de 102 CFU/g, para contagem padrão em placas de micro-organismos aeróbicos. Nas amostras, não foram detectados níveis de histamina e de compostos à base de enxofre. A proposta de trabalho objetivou, por fim, desenvolver alimentos e tecnologias que possam servir como padrões, permitindo que produtos de manipulação simples e que utilizem misturas de carne moída de diferentes espécies de pescado mantenham índices nutricionais adequados após o processamento.(AU)

ABSTRACT

Riedel's thyroiditis (RT) represents one type of IgG4-related thyroid disease (IgG4RTD) and the diagnosis involves quantitative immunohistochemistry showing dense lymphoplasmacellular inflammatory infiltrate consisting of IgG4-positive plasma cells with storiform fibrosis and obliterative phlebitis. We report a case of RT with progressive enlargement of the anterior neck, severe dysphagia, odynophagia, and dyspnea. The patient underwent surgical decompression of the airway, protection tracheotomy, and gastrostomy for nutritional intake 6 months after first symptoms. Complete resolution occurred after surgical treatment combined with prednisolone. Immunostaining revealed IgG4-positive plasma cells 12/HPF (high-power field) and the IgG4/IgG ratio 25%, values that were disproportionate to the intensity of the patient's symptoms. As to this case and the few cases described and analyzed in the literature, our impression is that there is no relation between the intensity of symptoms in RT with the total number of IgG4-positive plasma cells and the IgG4/IgG ratio, but more studies are needed.

ABSTRACT

BACKGROUND: Comorbidities are common in COPD and have been associated with reduced health status, increased health care utilization, all-cause hospitalization, and mortality. There is a scarcity of data on the relationship between comorbidities and functional capacity. OBJECTIVE: to evaluate the impact of comorbidities on functional capacity of COPD patients. METHODS: a cross-sectional study was conducted at two teaching hospitals in Fortaleza, Brazil. The functional capacity was assessed by spirometry and the 6-min walking test (6MWT). The health status was assessed by the St. George's respiratory questionnaire (SGRQ) and the COPD assessment test (CAT). The sample was stratified as having "none", "one" and "two or three" comorbidities groups. One-way ANOVA was used to compare means of the three groups and a multiple linear regression was run to predict the impact of comorbidities on 6MWT. RESULTS: Comorbidities (hypertension, coronary disease and diabetes) were found in 54% of the studied patients. The mean age of the 79 patients was 67±8 years and 55% were male. CAT scores increased from "no comorbidity" (17.9±7.7) to "one comorbidity" (22.8±6.8) and "two or three comorbidities" groups (24.2±10.2). A post hoc test showed a significant difference in the "no comorbidity" compared to the "two or three comorbidities" groups (p=0.01). The distance walked by the patients decreased from "no comorbidity" (386.1±83.2m) to "one comorbidity" (350±98m) and "two or three comorbidities" groups (312.6±91m). A post hoc test showed significant difference in the "no comorbidity" compared to "two or three comorbidities" groups (p=0.007). Numbers of comorbidities were independently associated with the 6MWT adjusting for age, severity of COPD and CAT scores. CONCLUSION: in the studied sample, the presence of comorbidities contributed to impair exercise capacity in patients with COPD.
