[ID 54107] O NUTRITION IMPACT SYMPTOMS (NIS) PODE SER UTILIZADO COMO UM INSTRUMENTO DE TRIAGEM NUTRICIONAL EM PACIENTES COM DOENÇA RENAL CRÔNICA NA POPULAÇÃO BRASILEIRA?
Authors: Mônica Batista Soares  , de Araújo Souza Bárbarah Gregório , Brito Campos Marina , Machado Schincaglia Raquel 
Published: September 2021

Objetivo: Adaptar e validar o uso da ferramenta Nutritional Impact Symptoms (NIS) como instrumento de triagem nutricional em indivíduos com DRC na população brasileira. Metodologia: Estudo do tipo transversal desenvolvido em um Hospital Universitário, baseado nos procedimentos de validação sugeridos por Beaton et al. (2000), American Educational Research Association, American Psychological Association e National Council on Measurement in Education (2014) e revisados por Muñiz, Elosua e Hambleton (2013). Resultados: Para a validação do NIS, utilizando-se a Avaliação Subjetiva Global (ASG) como padrão, foram realizadas as análises sequenciais, obtendo-se um coeficiente da correlação de Spearman classificado como moderado (ρ=0,51; p<0,001); um erro típico da medida absoluto de 0,46 e relativo de 30%; coeficiente de variação de 15% e ausência de diferenças entre avaliações médias (p=0,497). Embora a classificação entre o NIS e a ASG original tenham apresentado uma moderada correlação, sem diferenças entre as médias e um erro sistemático baixo, a concordância entre as variáveis apresentou uma amplitude alta no erro aleatório. Conclusão: A NIS foi adaptada, mas não validada para o público com doença renal em âmbito hospitalar, necessiatndo de uma avaliação com um maior número de pacientes para poder ser utilizada como parte de protocolos de avaliação nutricional com objetivo de rastreio da presença de desnutrição e posterior avaliação aprofundada da mesma.

Objetivo: Avaliar os efeitos sobre o desenvolvimento embrionário e gestacional em ratas prenhas expostas diariamente aos cogumelos Agaricus blazei e Ganoderma lucidum. Metodologia: Após a confirmação de prenhez (1º dia), os animais foram separados aleatoriamente em 5 grupos (n=6, cada): controle salina (Cs), A. blazei (Ab1-8, 1º - 8º dia), A. blazei (Ab9-19, 9º - 19º dia), G. lucidum (Gl1-8,1º - 8º dia) e G. lucidum (Gl1-19, 9º - 19º dia). Os animais receberam diariamente, via gavagem, 1,5 mL de cada cogumelo (100 mg/kg de pó liofilizado dissolvido em solução salina). No 20º dia gestacional, as fêmeas foram eutanizadas para a coleta de sangue (análises bioquímicas e hematológicas); rins e placenta (análises histológicas); cornos uterinos (análises morfométricas e morfológicas dos fetos). Resultados: Efeitos deletérios no perfil reprodutivo e gestacional das ratas e alterações nos parâmetros hematológicos não foram observados, como também hepatotoxicidade ou nefrotoxicidade materna. No entanto, ocorreu uma redução plasmática de colesterol total e triglicérides. O G. lucidum aumentou as células produtoras de glicogênio na placenta no período anterior à implantação. Quanto à prole ocorreu uma diminuição significativa no peso dos fetos de ambos os grupos expostos aos cogumelos. Conclusão: A administração oral dos cogumelos Agaricus blazei e Ganoderma lucidum em ratas prenhas positivamente reduziu o colesterol total e triglicérides, revelando um efeito cardioprotetor. O uso desses cogumelos durante o período gestacional foi seguro, não tendo apresentado efeitos teratogênicos, levando a uma redução de peso da prole, que pode ser útil em ocorrências do diabetes mellitus gestacional.

The article considered the problems caused by the need to adapt the system of higher education and vocational training to the dynamic changes of the globalized world. It stands out as interferences of the Bologna Process in Higher Education of Ukraine. This is an exploratory qualitative study. Among these closing considerations we highlight that most professors, associate professors, professors from various universities in Ukraine speak very negatively about this process, saying that we have inherited from the Bologna system its worst component - the modular credit system. This is, according to the unanimous opinion of Ukrainian teachers, which has led to the rapid degradation of domestic higher education since the assessment of knowledge (in parts!). It does not leave the student with an integral idea of the corresponding subject and, therefore, does not contribute to the acquisition of systemic knowledge.

Abstrak: Bakteri pereduksi sulfat atau Sulfate-reducing bacteria (SRB) adalah jenis bakteri obligat anaerob kemolitrotof memanfaatkan donor electron H2. Kemampuan SRB mereduksi sulfat menjadi sulfida mampu mengendapkan logam toksik meliputi Cd, Cu, dan Zn sebagai logam sulfida. SRB memerlukan substrat organik seperti asam piruvat yang dihasilkan oleh aktivitas anaerob lainnya. Mekanisme SRB dalam melakukan reduksi sulfat, sulfat digunakan sebagai sumber energi sebagai akseptor elektron dan menggunakan sumber karbon (C) sebagai donor elekton dalam metabolisme dan bahan penyusun sel. Pada kondisi anaerob bahan organik akan berperan sebagai donor elektron. Pembentukan senyawa sulfida melalui proses reduksi yang ditandai oleh penambahan elektron dari bahan organik yang menyebabkan turunnya konsentrasi sulfat dan naiknya pH lingkungan. SRB pada kawah air panas nirwana ini hidup secara anaerob pada suhu lingkungan 600C - 1000C dengan pH 7,4 tingkat kekeruhan air cukup keruh dan kandungan air yang mengandung blerang dengan indikator bau seperti telur busuk dan lingkungan sekitar terdiri dari sedimen batu kapur.

Abstract : Sulfate-reducing bacteria (BPS) is a type of chemolithotroph obligate anaerobic bacteria that utilize H2 electron donors. The ability of BPS to reduce sulfate to sulfide is able to precipitate toxic metals including Cd, Cu, and Zn as metal sulfides. BPS requires organic substrates such as pyruvic acid which is produced by other anaerobic activities. The BPS mechanism in reducing sulfate, sulfate is used as an energy source as an electron acceptor and uses a carbon source (C) as an electron donor in metabolism and cell building material. Under anaerobic conditions, organic matter will act as an electron donor. The formation of sulfide compounds through a reduction process is characterized by the addition of electrons from organic matter which causes a decrease in sulfate concentration and an increase in environmental pH. BPS in this nirvana hot spring crater lives anaerobically at an environmental temperature of 600C - 1000C with a pH of 7.4 the level of turbidity of the water is quite cloudy and the water content contains sulfur with an indicator of smell like rotten eggs and the surrounding environment consists of limestone sediments
