Abstract Soybean meal is an inexpensive plant origin protein which has been used in practical diets as a replacement of animal protein such as fish meal or chicken meal, due to the uneconomical price of animal protein diets. Consequently, a research study was conducted on some commercial species of Indian major carps i.e. Catla (Cattla cattla), Rohu (Labeo rohita) and Mrigala (Cirhinus mrigala) (Hamilton, 1822) to estimate optimum dietary protein requirement of soy bean meal in diet in an intensive polyculture. Three different diets (SBM I, SBM II and SBM III) were formulated by 80%, 50% and 20% replacement of fish meal with soybean meal from a 45% fish meal diet (control).Highest monthly mean weight gain was obtained by SBM II (with 35% CP and about 50% substitution of fish meal), while SBM III (45% Crude Protein and about 20% substitution of fish meal) was stood second. All tested diets respond enormously by producing high yield as compare to control diet, though SBM II generated highest yield among all. On the bases of the following research, it was revealed that the SBM can surrogate even50% fish meal without any augmentation of other amino acids in the diet of Indian major carps.

Resumo O farelo de soja é uma proteína de origem vegetal de baixo custo que tem sido usada em dietas práticas como um substituto da proteína animal, como farinha de peixe ou farinha de frango, devido ao preço não econômico das dietas com proteína animal. Consequentemente, um estudo/pesquisa foi realizado com algumas espécies comerciais de carpas principais indianas, ou seja, Catla (Cattla cattla), Rohu (Labeo rohita) e Mrigala (Cirhinus mrigala) (Hamilton, 1822), para estimar a necessidade ideal de proteína dietética de farelo de soja na dieta em uma policultura intensiva. Três dietas diferentes (SBM I, SBM II e SBM III) foram formuladas por 80%, 50% e 20% de substituição de farinha de peixe por farelo de soja de uma dieta de 45% de farinha de peixe (controle). O maior ganho de peso médio mensal foi obtido por SBM II (com 35% PB e cerca de 50% de substituição de farinha de peixe), enquanto SBM III (45% de proteína bruta e cerca de 20% de substituição de farinha de peixe) ficou em segundo lugar. Todas as dietas testadas respondem enormemente produzindo alto rendimento em comparação com a dieta controle, embora SBM II tenha gerado o maior rendimento entre todas. Com base na pesquisa a seguir, foi revelado que o SBM pode substituir até 50% da farinha de peixe sem qualquer aumento de outros aminoácidos na dieta das carpas principais indianas.

Fish and fish products are an outstanding source of essential protein and micronutrients. In cured meats, such as pâté, the technological characteristics are fundamental to the final quality of the product. The present study aimed to evaluate the effect of the addition of manioc starch, water and inulin on moisture, water holding capacity (WHC) and texture profile in pâtés using the underutilized marine fish bicuda (barracuda, Sphyraenatome) with total fat replacement by inulin. A Rotational Central Composite Design (RCCD) was used with the independent variables inulin, manioc starch, and water. Water, inulin, and manioc starch significantly influenced (p<0.05) the moisture content of pâtés, WHC, and texture, hardness, gumminess, and chewiness parameters. The technological action of inulin as a substitute for fat used in the formulations (3% to 6%) was underestimated. The percentages used were below perecentages of at least 20% of fat reported in the literature.Current legislation does not recommend WHR values and hardness parameters, only values for humidity. There is a need for revision of legislation to meet the characteristics of the identity pattern and quality of fish pâté.

El pescado y los productos pesqueros son una fuente excepcional de proteínas esenciales y micronutrientes. En embutidos (carne curada) como el paté, las características tecnológicas son fundamentales para la calidad final del producto. El presente estudio tuvo como objetivo evaluar el efecto de la adición de almidón de mandioca, agua e inulina sobre la humedad, la capacidad de retención de agua (WHC) y el perfil de la textura en patés fabricados con peces marinos subutilizados (barracuda, Sphyraena tome) con reemplazo total de grasa por inulina. Se utilizó un diseño compuesto central rotatorio (RCCD) con las variables independientes inulina, almidón de mandioca y agua. El agua, la inulina y el almidón de mandioca influyeron significativamente (p<0.05) en el contenido de humedad de los patés, WHC, y los parámetros de textura, dureza, gomosidad y masticabilidad. Se subestimó la acción tecnológica de la inulina como sustituto de la grasa en los contenidos utilizados en las formulaciones (3% a 6%). Los porcentajes utilizados estaban por debajo de lo que informa la literatura de al menos un 20% de grasa. La legislación actual no recomienda valores de WHR y parámetros de dureza, solo valores de humedad. Es necesario revisar la legislación para cumplir con las características del patrón de identidad y la calidad del paté de pescado.

Los cuerpos extraños alojados en la vía aéreodigestiva superior son un motivo de consulta frecuente para el otorrinolaringólogo. Uno de los más frecuentes son las espinas de pescado. En raras ocasiones, éstas migran hacia tejidos adyacentes y generan complicaciones importantes. Presentamos el caso de una paciente que tras la ingesta de pescado manifiesta sensación de cuerpo extraño faríngeo, odinofagia y dolor látero cervical derecho. Dada la ausencia de hallazgos a la exploración física y laringoscópica se realiza una tomografia computarizada cervical, visualizando un cuerpo extraño alojado en la glándula tiroidea. Se interviene mediante cervicotomía media, realizando la extracción de la espina sin complicaciones. El diagnóstico precoz y manejo adecuado es determinante para prevenir complicaciones en estos casos.

Foreign bodies in the aerodigestive tract are commonly confronted in otolaryngology practice. The most frequent are the fish bones. In rare cases they can move and cause numerous complications. We report the case of a patient that manifest the sensation of pharyngeal foreign body, after fish ingestion. She also referred odynophagia and right cervical pain. Physical and laryngoscopic examination were normal. A cervical CT was performed, where a foreign body lodged in the thyroid gland was visualized, median cervicotomy was done and the foreign body was extracted. Early diagnosis and adequate management are crucial to prevent complications in these cases.

OBJECTIVES: This study examined the salinity of soups provided at childcare centers by measuring the salinity for three years and providing basic data for sodium reduction.METHODS: The soup salinity was measured using a Bluetooth salinity meter from January 2015 to December 2017 at 80 childcare foodservice establishments enrolled in the Suseong Center for Children's Foodservice Management in Daegu.RESULTS: An analysis of the soup salinity each year showed that the salinity decreased significantly from 0.48% in 2015 to 0.41% in 2017, particularly in clear soups and soybean soups compared to other soups (P < 0.05). The salinity and sodium content in seafood soups (0.45% and 179.1 mg/100 g, respectively) were highest, followed by soybean soups (0.44%, 175.2 mg/100 g), with perilla seed soups containing the lowest (0.42%, 167.2 mg/100 g) (P < 0.05). The salinity was significantly higher in institutional foodservice establishments than small foodservice establishments (P < 0.001). The salinity and sodium content were the highest in foodservice establishments with a small number of measurements, and the salinity was the lowest in foodservice establishments with salinity measurements performed an average of 151 times each year (three times a week) or more (P < 0.05). The soup salinity was low in the order of winter, spring, summer, and autumn, and the salinity decreased significantly year by year in all seasons. (P < 0.05).CONCLUSIONS: The soup salinity was significantly lower in foodservice establishments where the salinity was measured more than three times a week, indicating that continuous salinity management is effective.

BACKGROUND: This study aimed to identify the relationship between exposure to bisphenol A (BPA) and seafood consumption using a nationally representative data of the general Korean population.METHODS: This study was conducted on 5,402 adults aged 19 years and older (2,488 men, 2,914 women) based on the second Korean National Environmental Health Survey (2012–2014). We stratified the data according to gender and analyzed urinary BPA concentrations in terms of sociodemographic characteristics, health behavior, dietary factor, and seafood consumption. In the high and low BPA exposure groups, the odds ratios (ORs) were calculated using logistic regression analysis according to the top 75th percentile concentration.RESULTS: In men, large fish and tuna and other seafood categories had significantly higher ORs before and after adjustment in the group who consumed seafood more than once a week than in the group who rarely consumed seafood, with an adjusted value of 1.97 (95% confidence interval [CI]: 1.12–3.48) and 1.74 (95% CI: 1.10–2.75), respectively. In the shellfish category, the unadjusted OR was 1.61 (95% CI: 1.00–2.59), which was significantly higher in the group who consumed seafood more than once a week than in the group who rarely consumed seafood. However, the OR after adjusting for the variables was not statistically significant. In women, the frequency of seafood consumption and the concentration of urinary BPA were not significantly associated.CONCLUSIONS: BPA concentration was higher in men who frequently consumed large fish and tuna, shellfish and other seafood in this study.

Norovirus (NoV) is the main cause of gastroenteritis outbreaks worldwide. Although NoV spreads mainly from person to person, it is estimated that a large proportion of NoV outbreaks are caused by foodborne transmission. Bivalve mollusks are one of the most important foods involved in NoV transmission to humans. Little is known about NoV prevalence in shellfish harvested and commercialized in Brazil. The aim of this study was to map, for the first time, the distribution of NoV contamination in oysters and mussels harvested and commercialized in the coast of Pernambuco state, northeast Brazil. A total of 380 mollusks (260 oysters and 120 mussels) were collected between February and August 2017 either directly from harvesting areas or obtained from beach vendors at 17 sites in Pernambuco. Samples were processed and tested for NoV contamination using a SYBR Green real-time PCR assay. All samples were negative for NoV GI or GII contamination, suggesting a low risk of NoV contamination from this food source during the study period. Additional surveys in different areas of the Brazilian coast are warranted to monitor the risk of NoV infection upon seafood consumption.

Abstract This study was conducted to determine an appropriate replacement of fishmeal with amino acids (AAs) and optimized protein levels in practical diets for Oreochromis niloticus with mean initial body weight 12.52±0.63g. Six experimental and a control diet (total 7 diets) divided into two groups, and a control diet (D1) containing 32% protein. The first group contained three diets that included different dietary protein levels, viz. 20 (D2), 25 (D3), and 30% (D4) with AAs when replacing fishmeal by plant protein sources. In the second group, the diets were contained 20 (D5), 25 (D6), and 30% (D7) without AAs. The best growth performance was achieved in fish fed with diet D1. Total feed intake was increased with an increase in dietary protein level with AAs. The specific growth rate showed a similar pattern with a significant difference between control, D4 and D7 compared to other groups. The feed conversion ratio decreased when protein levels in the diets increased. The protein efficiency ratio showed a similar performance, with a slight increase between the control diet and diets with AAs. However, insignificant differences (P>0.05) were observed between diets with and without AAs. An economic evaluation indicated that inclusion of low fishmeal in tilapia diets reduced the price/kg of diets compared to control.

Resumo Este estudo foi realizado para determinar uma substituição adequada de farinha de peixe com aminoácidos (AA) e níveis otimizados de proteína em dietas práticas para Oreochromis niloticus com peso corporal inicial médio de 12,52 ± 0,63 g. Seis dietas experimentais e controle (total de 7 dietas) divididas em dois grupos, e uma dieta controle (D1) contendo 32% de proteína. O primeiro grupo continha três dietas que incluíam diferentes níveis de proteína na dieta, viz. 20 (D2), 25 (D3) e 30% (D4) com AAs ao substituir a farinha de peixe por fontes de proteína vegetal. No segundo grupo, as dietas continham 20 (D5), 25 (D6) e 30% (D7) sem AAs. O melhor desempenho de crescimento foi alcançado em peixes alimentados com dieta D1. O consumo total de ração foi aumentado com o aumento do nível de proteína na dieta com AAs. A taxa de crescimento específico mostrou um padrão semelhante com uma diferença significativa entre o controle, D4 ​​e D7 em comparação com outros grupos. A taxa de conversão alimentar diminuiu quando os níveis de proteína nas dietas aumentaram. A taxa de eficiência protéica apresentou desempenho semelhante, com discreto aumento entre a dieta controle e as dietas com AAs. Entretanto, diferenças insignificantes (P> 0,05) foram observadas entre dietas com e sem AAs. Uma avaliação econômica indicou que a inclusão de farinha de peixe baixa em dietas de tilápia reduziu o preço / kg de dietas em relação ao controle.

Abstract The isolation of Escherichia coli from food is a major concern. Pathogenic strains of these bacteria cause diseases which range from diarrhea to hemolytic-uremic syndrome. Therefore the virulence genes in E. coli isolates from the mussel ( Mytella guyanensis) commercialized in Cachoeira, Bahia, Brazil were investigated. Samples were purchased from four vendors: two from supermarkets and two from fair outlets. They were conditioned into isothermal boxes with reusable ice and transported to the laboratory for analysis. E. coli strains were isolated in eosin methylene blue agar, preserved in brain-heart infusion medium with 15% glycerol and stored at -20 °C, after microbiological analysis. Virulence genes in the isolated strains were identified by specific primers, with Polymerase Chain Reaction. Twenty-four isolates were obtained, with a prevalence of elt gene, typical from enterotoxigenic infection, in 75% of the isolates. The stx and bfpA genes, prevalent in enterohemorragic and enteropathogenic E. coli, respectively, were not detected. The occurrence of elt virulence-related gene in the E. coli isolates of Mytella guyanensis reveals urgent improvement in food processing, including good handling practices, adequate storage and cooking before consumption, to ensure consumer's health.

Resumo O isolamento de Escherichia coli a partir de alimentos é uma grande preocupação, pois cepas patogênicas desta bactéria podem causar desde diarreia até síndrome hemolítico-urêmica. Diante do exposto, o objetivo do trabalho foi pesquisar genes de virulência em isolados de Escherichia coli provenientes do sururu Mytella guyanensis comercializado na cidade de Cachoeira, Bahia, Brasil. As amostras foram adquiridas de quatro comerciantes, sendo duas de mercados e duas em pontos de venda na feira livre da cidade de Cachoeira, acondicionadas em caixas isotérmicas com gelo reutilizável e transportadas até o laboratório para a análise. Após a análise microbiológica, as cepas de Escherichia coli foram isoladas em ágar Eosina Azul de Metileno e preservadas em caldo Brian Heart Infusion e glicerol a 15% e mantidas a - 20° C. A identificação dos genes de virulência nas cepas isoladas foi realizada utilizando primers específicos, por meio da Reação em Cadeia da Polimerase. Foram obtidos 24 isolados de Escherichia coli, destes a prevalência do gene elt , característico de Escherichia coli enterotoxigênica, foi de 75% dos isolados. Não houve a detecção dos genes stx e bfpA nos isolados, os quais são prevalentes nas cepas de Escherichia coli enterohemorrágica e Escherichia coli enteropatogênica, respectivamente. A presença do gene elt relacionado à virulência de Escherichia coli nos isolados de Mytella guyanensis revela a necessidade da melhoria no processamento, incluindo boas práticas de manipulação, armazenamento adequado e cocção previa ao consumo, visando a garantia da saúde do consumidor.

Abstract The lack of knowledge about the majority of fish species harvested in Amazonian small-scale fisheries, in association with impacts from hydroelectric power plants, may lead to biodiversity loss and a decrease in the protein food supply for riverine Amazonians. This study uses existing datasets on fisheries and riverine developmental projects to infer effects associated with fish losses where actual data and outcomes are not available. The targeted fish species' status may be regarded as either threatened or there being no knowledge of their conservation requirements, biology or ecology. Among the 90 Amazonian fish species that are the most important for the diet of the riverine fishers, 78% are not assessed or their biological information is unknown, according to the IUCN Red List. Consequently, the effects created by the thoroughly disregarded trade-off between energy generation and food security in the planning of Amazonian land use have been worsened by the lack of biological and ecological information on fish species.

Resumo A falta de conhecimento sobre a maioria das espécies alvo de comunidades pesqueiras da Amazonia, associada ao impacto das hidrelétricas pode levar ao descréscimo da biodiversidade e na disponibilidade de proteína para os ribeirinhos da Amazônia. As espécies alvo são vulneráveis ou pouco conhecidas em sua biologia ou ecologia. Dentre 90 espécies de peixes importantes na dieta dos ribeirinhos, 78% não são estudadas ou sua biologia é desconhecida, de acordo com a lista da UICN. Dessa forma, os efeitos criados pela negligenciada relação de custo e benefício entre a produção de energia e a segurança alimentar no planejamento da Amazônia tem ainda piorado a situação de desconhecimento sobre as espécies de peixes.

The 2019 hepatitis A outbreak has become increasingly prevalent among adults in Korea and is the largest outbreak since that in 2009–2010. The incidence in the current outbreak is highest among adults aged 35–44 years, corresponding to the peak incidence among those aged 25–34 years 10 years ago. This may indicate a cohort effect in the corresponding age group. Causes of these repeated outbreaks of hepatitis A in Korea are low level of immunity among adults, Korean food culture that consumes raw seafood such as salted clam and inadequate public health system. Among countermeasures, along with general infectious disease control measures including control of the infectious agent, infection spread, and host, urgent actions are needed to review the vaccination policy and establish an adequate public health system.

OBJECTIVES: Pathogenic Vibrio species are widely distributed in warm estuarine and coastal environments, and can infect humans through the consumption of raw or mishandled contaminated seafood and seawater. For this reason, the distribution of these bacteria in South Korea was investigated.METHODS: Seawater samples were collected from 145 coastal area points in the aquatic environment in which Vibrio species live. Environmental data (i.e., water temperature, salinity, turbidity, and atmospheric temperature) was collected which may help predict the distribution of the species (data not shown). Seawater samples were filtered, and incubated overnight in alkaline peptone water, at 37°C. Using species-specific polymerase chain reaction methods, screening tests were performed for the hlyA, ctxA, vvhA, and tlh genes. Clones of pathogenic Vibrio species were isolated using 3 selective plating media.RESULTS: In 2017, total seawater isolation rates for Vibrio vulnificus, Vibrio cholerae (non-pathogenic, non-O1, non-O139 serogroups), and Vibrio parahaemolyticus were 15.82%, 13.18%, 65.80%, respectively. However, in 2018 isolation rates for each were 21.81%, 19.40%, and 70.05%, respectively.CONCLUSION: The isolation rates of pathogenic Vibrio species positively correlated with the temperature of seawater and atmosphere, but negatively correlated with salinity and turbidity. From 2017 to 2018, the most frequent seawater-isolated Vibrio species were V. parahaemolyticus (68.10 %), V. vulnificus (16.54%), and non-toxigenic V. cholerae (19.58%). Comprehensive monitoring, prevention, and control efforts are needed to protect the public from pathogenic Vibrio species.

Isolating the effects of a single nutrient or food in relation to health outcomes including increased skeletal muscle mass is a challenging task because dietary constituents are highly correlated and synergistic. Hence, diet pattern analysis may be used to investigate the role of certain diets in health outcomes. The present study investigated the dietary patterns and their relationship to skeletal muscle mass in Korean adults. Data were extracted from the 2008–2011 Korea National Health and Nutrition Examination Surveys. To explore the dietary patterns of the study subjects, factor analysis was performed using data obtained from a 24-hour recall. The skeletal muscle index according to dietary pattern scores was then investigated to estimate the changes in skeletal muscle mass. Three patterns were initially identified from the factor analysis. Of these vegetables and fish (VF) pattern was the primary factor with high reliability and was a common factor in sex-separated analyses. The VF pattern scores were positively associated with increased skeletal muscle mass in both men and women. Further analysis according to quartile levels of VF pattern scores showed a positive association between skeletal muscle mass and VF pattern in men but not in women. These results suggest that dietary patterns focused on vegetables and seafoods may contribute to increased skeletal muscle mass in Korean men but that sex difference should be considered in nutrition care for skeletal muscle health.

This study aimed to determine the status of common parasitic disease in Korea in 2019. Twelve parasitic diseases were selected: toxocariasis, anisakiasis, paragonimiasis, sparganosis, cysticercosis, toxoplasmosis, clonorchiasis, enterobiasis, trichuriasis, trichomoniasis, cryptosporidiosis, and malaria. Their biology, epidemiology, pathogenesis, symptoms and signs, diagnosis, treatment, and prognosis were evaluated. Of the parasitic diseases, toxocariasis was the most prevalent according to serological results. Anisakiasis should be considered when acute gastrointestinal symptoms occur with a recent past history of raw seafood ingestion. Paragonimiasis, sparganosis, and cysticercosis can be diagnosed using an enzyme-linked immunosorbent assay; thus, enzyme-linked immunosorbent assay needs to be performed for suspected cases. Toxoplasmosis and cryptosporidiosis are opportunistic infections. The symptoms and signs are aggravated under immunocompromised conditions. Although the egg positivity rate of Clonorchis sinensis is higher than that of other intestinal parasitic diseases, encountering patients with complaints of symptoms caused by clonorchiasis is rare because the worm burden is low. Trichomoniasis is usually managed by gynecologists; therefore, it should be included in the differential diagnoses of vaginal diseases. The annual number of malaria cases has decreased, although it remains at approximately 500 cases per year. Malaria should be suspected when symptoms such as intermittent fever, headache, and splenomegaly are noted especially when the patients reside near demilitarized zones. Although the prevalence and number of reported cases of parasitic diseases have decreased in Korea, we should consider parasitic diseases in the list of differential diagnoses.

We conducted this study to compare the awareness and attitude of Busan housewives about consuming marine products. The survey was conducted from April 10 to May 31, 2019 by using a questionnaire. The degree of preference of seafood was higher among individuals in their 40s than those in the other age groups. Among the women in their 30s, 40s, 50s and 70s, the reason for liking seafood was ‘taste’, and for those in their 60s it was ‘nutrition’. Overall the most common reason for disliking seafood was the ‘fishy smell (37.4%)’. Conception degree of nutritive value of seafood was higher among individuals in their 30s and 40s than that for those individuals in their 50s, 60s and 70s. As for the price of seafood, the wives over 40s thought seafood was more expensive than did those wives in their 30s. The younger the individuals were, the lower was the perceived degree of safety was 49.8% of the subjects reported that the main concern for purchase was ‘freshness’. The perceived degree of safety for imported seafood was better for the wives in their 60s and 70s than that for those wives in their 30s, 40s and 50s. The confidence level for local Korean seafood was higher for the wives in their 60s than that for the wives in their 50s. The degree of preference for seafood was moderate overall, except for Jellyfish. Age was positively correlated with conception for safety and dietary attitude (P<0.01), whereas age was negatively correlated with monthly food expenditure, nutrition knowledge and intake requirements (P<0.01). Preference for seafood was positively correlated with conception for safety (P<0.05), nutrition knowledge (P<0.05), dietary attitude (P<0.01), awareness for nutritive value (P<0.01) and intake requirements (P<0.01). Laws and regulations should be reinforced in order to promote eating more seafood and periodic research to determine the actual amount of consumed seafood and people's preferences should be conducted.

BACKGROUND/OBJECTIVES: The elderly are reported to have a high prevalence of nutritional anemia when they have lower intakes of nutrients or chronic diseases. This study was conducted to compare nutritional status according to nutritional anemia and to determine associations between nutritional anemia and chronic diseases in Korean elderly. MATERIALS/METHODS: This study utilized data on 3,258 elderly aged ≥ 65 years gathered during the 6(th) Korea National Health and Nutrition Examination Survey 2013–2015. Subjects were divided into nutritional anemia (NA) group (n = 415) and non-NA group (n = 2,843) by hemoglobin concentration. Nutrient intakes were assessed using dietary intake data obtained using the 24-hour recall method. The odds ratios (ORs) for nutritional anemia by chronic diseases were determined. Statistical analysis was performed using SPSS Ver. 23.0. RESULTS: Of 3,258 subjects, 12.7% had nutritional anemia. Intakes of potatoes, pulses, and mushrooms by males and potatoes, fruits, meats, eggs, and seafood by females were significantly lower in NA group than in non-NA group. The proportion of the subjects whose intakes of protein, vitamin A, vitamin B₁, vitamin B₂, niacin, and iron less than estimated average requirement (EAR) were significantly higher in NA group compared to non-NA group. After adjusting for age, the number of family members, energy intake, and alcohol drinking, ORs for nutritional anemia in the subjects with diabetes and myocardial infarction or angina pectoris were significantly higher by 1.74 times and 1.59 times as compared to the subjects without those diseases, respectively. However, ORs for nutritional anemia in the subjects with obesity, abdominal obesity, and hypertriglyceridemia were significantly lower by 0.64 times, 0.60 times, and 0.59 times as compared to the subjects without those diseases, respectively. CONCLUSIONS: The results of this study suggested that nutritional management should be done to enable the Korean elderly to consume foods with high hematopoietic nutrients density to prevent nutritional anemia. Korean elderly need to make regular efforts to check for nutritional anemia.

OBJECTIVES: This study was undertaken to compare dietary life of the elderly living alone and in a family, and to compare differences based on gender, for the 2013-2016 Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: The subjects included 2,612 elderly people aged over 65 years who participated in the health survey, health examination and nutrition survey. Subjects on a diet therapy were excluded. This study analyzed the general characteristics, dietary habits, daily energy and nutrient intakes, CPF ratio, estimated average requirement (EAR), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR), index of nutrient quality (INQ), and food consumption of the elderly living alone and in a family. We also compared the differences based on gender. RESULTS: Daily intake of food, water, dietary fiber, potassium, retinol, and riboflavin were low in the male elderly subjects living alone. The elderly living with family revealed higher NAR and MAR as compared to the elderly living alone. Although all MAR values were <1, the elderly living alone had lower values. Considering the intake of food, the consumption of seaweed, fish and shellfish, and oils (animal) was higher in elderly men living with families, whereas women living with families consumed more vegetables, fruits, seaweeds and seafood, as compared to their counterparts living alone. Furthermore, analyzing the foods consumed by the elderly people living alone, female subjects consumed more seaweed, milk and animal oil as compared to male subjects. CONCLUSIONS: The results of this study indicate that the elderly living alone have poor nutrient intake as compared to the elderly living with families. Based on this research data, we recommend that it is necessary to improve the health and nutritional status of the elderly living alone.

Abstract INTRODUCTION: Enterobacter cloacae is a clinically important bacterium from the Enterobacteriaceae family. This study evaluated resistance of E. cloacae strains from fish (n=14) and shrimp (n=9) to colistin. METHODS: Biochemical identification and antimicrobial susceptibility tests were carried out in an automated Vitek®2 instrument. RESULTS: Colistin resistance was observed in 21.4% and 66.7% of the strains from fish and shrimp, respectively. We observed minimum inhibitory concentrations of ≥16 mg/L and ≤5 mg/L in 8 and 15 of all strains, respectively. CONCLUSIONS: Fish and shrimp can carry drug-resistant enterobacteria, which can be of clinical interest.
