Brazilian kefir: structure, microbial communities and chemical composition

Microbial ecology and chemical composition of Brazilian kefir beverage was performed. The microorganisms associated with Brazilian kefir were investigated using a combination of phenotypic and genotypic methods. A total of 359 microbial isolates were identified. Lactic acid bacteria (60.5%) were the major isolated group identified, followed by yeasts (30.6%) and acetic acid bacteria (8.9%). Lactobacillus paracasei (89 isolates), Lactobacillus parabuchneri (41 isolates), Lactobacillus casei (32 isolates), Lactobacillus kefiri (31 isolates), Lactococcus lactis (24 isolates), Acetobacter lovaniensis (32 isolates), Kluyveromyces lactis (31 isolates), Kazachstania aerobia (23 isolates), Saccharomyces cerevisiae (41 isolates) and Lachancea meyersii (15 isolates) were the microbial species isolated. Scanning electron microscopy showed that the microbiota was dominated by bacilli (short and curved long) cells growing in close association with lemon-shaped yeasts cells. During the 24 h of fermentation, the protein content increased, while lactose and fat content decreased. The concentration of lactic acid ranged from 1.4 to 17.4 mg/ml, and that of acetic acid increased from 2.1 to 2.73 mg/ml. The production of ethanol was limited, reaching a final mean value of 0.5 mg/ml.The authors acknowledge Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES) for scholarshipsand and CAARG - Cooperativa Agricola Alto Rio Grande Ltda.

Depressão e auto-estima entre acadêmicos de enfermagem

CONTEXTO: Há evidências sobre o aumento dos casos de depressão e suas conseqüências na vida das pessoas. OBJETIVOS: Este estudo objetivou conhecer sinais indicativos de depressão e níveis de auto-estima entre acadêmicos de enfermagem, correlacionando esses indicadores. METODOLOGIA: aplicou-se 2 escalas de avaliação (depressão e auto-estima), auto-respondidas por 242 alunos do 1º, 2º e 3º anos de enfermagem que concordaram em participar. RESULTADOS: Idade entre 17 e 44 anos, sendo 40% acima dos 25, 4,4% não solteiros e 4,9% homens, indicando mudança no perfil dos alunos. Encontrou-se 80,8% de alunos sem depressão sendo que todos com altos níveis de estima pessoal (17%) estavam neste grupo. Os demais (80,4%) tinham níveis médios de auto-estima. A porcentagem de disforia (10,3%) e de depressão moderada e grave (6,7%) bem como os níveis de auto-estima condizem com os índices referidos na literatura. CONCLUSÕES: a freqüência de depressão entre estudantes está em níveis esperados, porém níveis de estima pessoal estão abaixo.BACKGROUND: There is growing evidence about the increasing incidence of depression and the consequences in people's lives. OBJECTIVE: This study aymed to describe and correlate depression symptoms and self-esteem levels among nursing students. METHODS: 242 first, second and third-year nursing students agreed to participate and answered two depression scales and one self-esteem assessment instrument. RESULTS: Participants were between 17 and 44 years old; 40% were older than 25; 4.4% were not single and 4.9% were men. These results indicate that the students' profile is changing. 80.8% of students did not present any signs of depression and all students with high self-esteem scores belonged to this group. The remaining (80.4%) presented average self-esteem levels. Levels of dysphoria (10.3%), moderate and severe depression (6.7%) and low and average self-esteem correspond to results mentioned in literature. CONCLUSION: Depression symptoms among nursing students are in accordance with the literature, but measures of self-esteem are below the expected levels

A Investigação e a escrita: Publicar sem Perecer

Research and Writing: Publish do not Perish is a collection of texts published in Portuguese, based on the problematization of a five-year experience of advanced extracurricular training in information literacy, writing and scientific publication (i.e., Publish do not Perish: Survive the Stampede). It is a questioning of the role of science in a context that appears to reproduce neoliberalism and the commodification of academia. This work results from the collaboration of national and international authors who consider a diversity of theoretical and empirical fields that deal with that phenomenon. This book aims to identify and question the subsequent problems, trying to point out solutions to the growing malaise in the academic world

A RELAÇÃO ENTRE O USO EXCESSIVO DE REDES SOCIAIS E A SAÚDE MENTAL DOS JOVENS

This study explores the relationship between excessive social media use and mental health in young people. The research reveals that intense use of these platforms is associated with increased symptoms of depression and anxiety, reflecting the growing concern about the psychological impact of social media. Evidence analysis points out that frequent use contributes to issues such as low self-esteem and stress. The literature review indicates that both young adults and adolescents are negatively affected, showing a significant increase in emotional disorders due to prolonged exposure to social media. The main objective of the work is to better understand how excessive social media use influences mental health and to suggest strategies to mitigate these adverse impacts.Este estudo explora a relação entre o uso excessivo de redes sociais e a saúde mental dos jovens. A pesquisa revela que o uso intenso dessas plataformas está associado a um aumento dos sintomas de depressão e ansiedade, refletindo a crescente preocupação com o impacto psicológico das redes sociais. A análise das evidências aponta que o uso frequente dessas redes contribui para problemas como baixa autoestima e estresse. A revisão bibliográfica indica que tanto jovens adultos quanto adolescentes são afetados negativamente, apresentando um aumento significativo nos transtornos emocionais devido à exposição prolongada a redes sociais. O objetivo principal do trabalho é compreender melhor como o uso excessivo de redes sociais influencia a saúde mental e sugerir estratégias para mitigar esses impactos adversos

Análise de material informativo em DVD na adaptação de idosos usuários de aparelho de amplificação sonora individual

Objetivo Verificar a eficácia do DVD “Conhecendo e Aprendendo sobre meu Aparelho Auditivo” como ferramenta no processo de adaptação do aparelho de amplificação sonora individual (AASI) em idosos. Métodos Participaram dessa pesquisa 27 indivíduos, divididos em dois grupos: grupo controle, que recebeu as orientações fonoaudiológicas e o manual técnico de instruções que acompanhava o AASI retroauricular adaptado; e grupo experimental, que recebeu as mesmas orientações do grupo controle, acrescidas do referido DVD. A eficácia do DVD foi mensurada por meio do instrumento específico de habilidades de manuseio com o AASI Practical Hearing Aid Skills Test, usando-se análise estatística-descritiva e o teste não paramétrico de Mann-Whitney. Resultados O grupo experimental obteve melhor desempenho nas tarefas de limpeza do AASI e molde auricular, manipulação do controle de volume, manuseio da bobina telefônica e posicionamento correto do telefone na orelha.

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions. Please cite this data paper when using the data in publications. We also request that researchers and teachers inform us on how they are using the data
