Abalone under moderate heat stress have elevated metabolic rates and changes to digestive enzyme activities.

Abalone around the world are subject to increasing frequency of marine heatwaves, yet we have a limited understanding of how acute high temperature events impact the physiology of these commercially and ecologically important species. This study examines the impact of a 5 °C temperature increase over ambient conditions for six weeks on the metabolic rates, digestive enzyme activities in the digestive gland, and digestive efficiency of Red Abalone (Haliotis rufescens) and Paua (H. iris) on their natural diets. We test the hypothesis that abalone digestive function can keep pace with this increased metabolic demand in two separate experiments, one for each species. H. iris had higher food intake in the heat treatment. Both species had higher metabolic rates in the heat treatment with Q10 = 1.73 and Q10 = 2.46 for H. rufescens and H. iris, respectively. Apparent organic matter digestibility, protein digestibility, and carbohydrate digestibility did not differ between the heat treatment and the ambient (control) treatment in either experiment. H. rufescens exhibited higher maltase, alanine-aminopeptidase, and leucine-aminopeptidase activities in the heat treatment. Amylase, ß-glucosidase, trypsin, and alkaline phosphatase activities in the digestive gland tissue did not differ between temperature treatments. H. iris exhibited lower amylase and ß-glucosidase activities in the heat treatment, while maltase, trypsin, leucine-aminopeptidase, and alkaline phosphatase activities did not differ between treatments. We conclude that over six weeks of moderate heat stress both abalone species were able to maintain digestive function, but achieved this maintenance in species-specific ways.

Quality control of enteral nutrition therapy in cancer patients at nutritional risk.

INTRODUCTION: Quality indicators in nutritional therapy (QINTs) allow for the practical assessment of quality in the management of enteral nutrition therapy (ENT) among hospitalized patients. OBJECTIVE: To control ENT quality in cancer patients at nutritional risk. METHODS: A prospective, observational study was performed with cancer patients over 19 years of age who had undergone exclusive ENT for at least 72 h. Nutritional Risk Screening was used to assess nutritional risk; in the presence of nutritional risk, the Subjective Global Assessment (SGA) was used. Six QINTs were applied. RESULTS: Our study included 211 patients (mean age: 59 ± 10 years, 67.3% men). Most common cancer diagnoses were head and neck (68.2%) and gastrointestinal (18%). Nutritional risk was identified in 93.3% (n = 197) of patients; SGA identified malnutrition in 84.2% of patients (n = 166). ENT was used for 9.7 ± 7 days, presenting a daily deficit of -243.1 ± 141 ml of dietary volume, -363.3 ± 214.1 kcal, and -14.2 ± 8.41 g of protein. Three of the six QINTs were in accordance with the proposed goal: frequency of SGA application, calculations of nutritional needs, and frequency of diarrhea. Three of the six QINTs were in disagreement with the proposed goal: ENT infused volume exceeding 70% of prescribed volume, frequency of digestive fasting exceeding 24 h, and frequency of constipation. Prescriptions for anticholinergic drugs (p = 0.023) and diuretics (p = 0.007) were associated with diarrhea. CONCLUSION: Nutritional risk and malnutrition are frequent among ENT cancer patients. Quality control in ENT was moderately impaired by episodes of fasting and intestinal motility disorders.

Extensão Médica Acadêmica: um projeto da Faculdade de Medicina da Universidade de São Paulo para treinamento clínico e humanização do cuidado em saúde de alunos da medicina, nutrição e fisioterapia / “Extensão Médica Acadêmica”: healthcare humanization and clinical training of medicine, nutrition and physical therapy students from the School of Medicine of University of São Paulo

A Extensão Médica Acadêmica (EMA) foifundada em 1998 na FMUSP visando à formação de médicos que valorizam o exame clínico e o relacionamentohumano. É um projeto de voluntariado atualmente organizado por estudantes de medicina, fisioterapia e nutrição da USP. O EMA é sustentado por três pilares: ensino, assistência e pesquisa. O projeto é realizado aos sábados em dois bairros carentes da cidade de SãoPaulo, e tem como objetivo oferecer um atendimento ambulatorial gratuito de qualidade, que priorize cuidados em saúde e humanização na relação médico-paciente. Os pacientes são atendidos por alunos e os casos sãodiscutidos com profissionais de saúde, e durante a semana são realizadas reuniões com todos os membros doprojeto, na Faculdade de Medicina da USP, contribuindo para a consolidação e aprofundamento dos conceitos em saúde. Este modelo de ensino complementa os estudos em sala de aula, pois permite o desenvolvimento de habilidades geralmente pouco exploradas durante o início da graduação tradicional. O EMA incentiva seus alunos a valorizarem a relação médico-paciente desde o primeiroano da graduação. Assim, o projeto tem êxito em reunir pessoas dispostas a lidar com pacientes, aprender sobresaúde e ensinar outros estudantes. Como resultado, muitos de seus membros continuam a participar do projeto após o término da faculdade, tornando-se orientadores comprometidos a passar adiante o conhecimento adquirido durante sua prática profissional...

The Academic Medical Extension (EMA) is a volunteer project of the School of Medicine of University of São Paulo organized by students of Medicine, Physical Therapy and Nutrition of University of São Paulo. It was founded in 1998 in order to provide a better academic development to students who value physical examination and human relations, besides providing to students in the beginning of graduation an early contact with patients and promotingan exchange of information between those three areas of health. EMA is sustained by three pillars: assistance,education and research, thus constituting an alternative tocommunity-based education and assistance with a focus on humanization. The project is carried in two regions in the city of São Paulo and aims to offer these needy populationsa free ambulatory care with quality, promote health and prevention. On Saturdays, undergraduate students see the patients and discuss the clinical case with a health professional; once a week, they attend a meeting with their group, which includes students of the three areas of health. During this meeting, the students report the clinical case and are assisted by other students to conduct the case and teachwhat they’ve learnt about the patient, collaborating with the establishment and deepening of the concepts in health. The project seeks to encourage their students since the first yearof college to value the physician-patient relationship. Thus, it brings together people willing to work ithout the intention to earn a profit, but to learn more about health and to teachother students. As a result, members still participate in the project after graduation, as doctors committed to pass on their experience and knowledge...
