Deep Learning Techniques to Improve the Performance of Olive Oil Classification

The olive oil assessment involves the use of a standardized sensory analysis according to the “panel test” method. However, there is an important interest to design novel strategies based on the use of Gas Chromatography (GC) coupled to mass spectrometry (MS), or ion mobility spectrometry (IMS) together with a chemometric data treatment for olive oil classification. It is an essential task in an attempt to get the most robust model over time and, both to avoid fraud in the price and to know whether it is suitable for consumption or not. The aim of this paper is to combine chemical techniques and Deep Learning approaches to automatically classify olive oil samples from two different harvests in their three corresponding classes: extra virgin olive oil (EVOO), virgin olive oil (VOO), and lampante olive oil (LOO). Our Deep Learning model is built with 701 samples, which were obtained from two olive oil campaigns (2014–2015 and 2015–2016). The data from the two harvests are built from the selection of specific olive oil markers from the whole spectral fingerprint obtained with GC-IMS method. In order to obtain the best results we have configured the parameters of our model according to the nature of the data. The results obtained show that a deep learning approach applied to data obtained from chemical instrumental techniques is a good method when classifying oil samples in their corresponding categories, with higher success rates than those obtained in previous works.Ministerio de Economía y Competitividad TIN2017-88209-C2-2-

Los riesgos nutricionales en escolares que pertenecen a familias de clase baja de la costa catarinense

The objective of the present study was to assess nutritional risks of 5-12 year-old low family income students enrolled in public schools in the city of Camboriú - SC. We evaluated 819 students (579 children and 240 adolescents). The nutritional risks found were related to anthropometrical classification, and it was observed that 78% of the sample was eutrophic, 13% undernourished, and 9% overweight. Food intake analysis showed high consumption of proteins (48%) and low consumption of carbohydrates (96%), vegetables (80%), fats (68%), cereals (68%) and fruits (48%). Socio-economic data showed that class D was predominant (43%), followed by classes C (30%), E (22%) and B (5%). Iron deficiency anemia was diagnosed in 46% of the students. The present study suggests that more efficient intervention strategies can be developed through identification, diagnosis, and analysis of nutritional factors, highlighting nutritional matters such as an essential health promotion component.El presente estudio tuvo como objetivo verificar los riesgos nutricionales de los escolares entre 5 y 12 años de edad de las familias de clase baja pertenecientes a la red de enseñanza pública de la ciudad de Camboriú - SC.

Quality of life in patients with dysphagia after radiation and chemotherapy treatment for head and neck tumors

Objective: The aim of this study is to analyze subjectively, using the SWAL-QOL questionnaire, swallowing dys function and associated factors after treatment with radiotherapy and chemotherapy in patients treated for head and neck cancer. Material and Methods: This is a cross-sectional study, based on the selection of patients with tumors of the head and neck area, treated with radiotherapy with or without chemotherapy during the years 2000 to 2006 at the Oncology Institute of Juiz de Fora. The data were analyzed using SPSS 15.0 software, and were evaluated using the chisquare test to compare differences in proportions between groups. The statistical significance level was set at 5%. Results: It was observed that with respect to foods of solid consistency, there was a statistically significant difference for mouth tumors (p<0.01), with a tendency in this group to use softer foods, easier to chew (stews, boiled vegtables, creamy soups, canned fruit). With reference to the domains of the SWAL-QOL, the location of the tumor in the mouth was statistically associated with the lowest quality of life in the symptoms domain (p<0.05). The female gender variable was associated with the lowest perceived quality of life in several domains, namely swallowing (p=0.02); fatigue (p=0.008); symptoms (p=0.009). Age (split below and above 60 years) was not associated with differences in perceived quality of life in any domain. Conclusion: Tumor in the mouth and the total dose of radiation in the superior fossa were associated with the lowest quality of life in the symptoms domain. The female gender variable was associated with the lowest perceived quality of life in several domains This study shows that speech therapy should maintain a presence in the teams, to then guide the rehabilitation of organic dysphonia and mechanical dysphagia possibly afflicting patients after cancer treatment with radiation therapy and chemotherapy

Complications of Covid-19: Developments for the unified health system [Complicações da Covid-19: Desdobramentos para o sistema único de saúde]

Covid-19 is an infectious severe acute respiratory syndrome, caused by Coronavirus, which quickly reached pandemic levels. In July/2020, Brazil was the second country most affected by the disease, exceeding two million cases. Despite the increasing scientific literature on Covid-19, its containment is still compromised by the lack of understanding about its determinants and complications. This article presents a discussion on aspects related to Covid-19 complications and its effects on Unified Health System (SUS), aiming at planning new coping strategies. Additionally, it is pointed out that the overload of the health system does not result only from aspects associated with the assistance to Covid-19, but adds to the pre-existing health needs, whose care strategies were postponed and/or changed due to the actions transmission control. It is evident, then, the need to reinforce the action of Primary Health Care as the ordering of care in SUS, acting in the management of the reorganization of flows and in the improvement of the physical structures of the units. To this end, the end of measures to limit health resources is essential, since not only does the success of coping with Covid-19 depend on this, but also the future of SUS and Brazilian’s health

Casamentos duradouros:o uso de entrevistas e o TAT na análise psicanalítica da relação conjugal

This article aims at reflecting on long-lasting marriages by studying the dynamics (conscious and unconscious) of established matrimonial relationships. At first, we use the theoretical socio-historic references on the existing modalities of marriage throughout history, and then we suggest a psychoanalytical analysis of three couples. Data collection was carried out by means of semi-open interviews with the couple, and T.A.T. cards 2, 4, 5, 10 and 16 were used with each spouse separately. Results showed that marriages lasted mainly due to the establishment of complementary pairs and to a traditional model of marriage, in which emphasis is put on raising the children and structuring the family, leaving aside their own conjugality.El objetivo de este artículo es construir reflexiones sobre los matrimonios duraderos, a través del estudio de la dinámica (consciente e inconsciente) de las relaciones conyugales establecidas. Será iniciado con el referencial teórico socio-histórico llevando en consideración las modalidades existentes de matrimonios, a lo largo del tiempo, y, posteriormente, es propuesto un análisis psicanalítica en tres parejas investigadas. La recolección de datos fue realizada por medio de entrevistas semi-abiertas con la pareja escogida, enseguida, la aplicación individual de las tablas 2, 4, 5, 10 16 del T.A.T. con cada cónyuge. Los resultados demostraron que la duración de los matrimonios se relacionan prioritariamente con la formación de pares complementarios y a un modelo tradicional de matrimonio, en que el énfasis era puesta en la criación de los hijos y la estructuración familiar, inclusive contra la propia relación conyugal.Cet article a pour objectif de proposer des réflexions portant sur des mariages durables à travers la dynamique (consciente et inconsciente) des relations conjugales déjà établies. Nous commençons par le référentiel théorique socio-historique à propos des modalités de mariage existant tout au long de l’histoire ; ensuite, nous proposons une analyse psychanalytique de trois couples étudiés. Les données ont été obtenues par l’intermédiaire d’entretiens semi-ouverts avec le couple. Ensuite, nous avons utilisé les planches 2, 4, 5, 10 et 16 du T.A.T. avec chaque conjoint individuellement. Les résultats ont montré que la préservation des mariages correspondait plutôt à la formation de paires complémentaires et à un modèle traditionnel de mariage où il s’agit plutôt d’élever les enfants et de structurer la famille au détriment de la conjugalité.O objetivo deste artigo é tecer reflexões acerca dos casamentos duradouros, através do estudo da dinâmica (consciente e inconsciente) das relações conjugais estabelecidas. Iniciamos com o referencial teórico sócio-histórico acerca das modalidades existentes de casamento, ao longo do tempo, e, posteriormente, propomos uma análise psicanalítica de três casais pesquisados. A coleta de dados foi realizada por meio de entrevistas semi-abertas com o casal, em seguida, a aplicação das pranchas 2, 4, 5, 10 e 16 do T.A.T. com cada cônjuge, individualmente. Os resultados demonstraram que a manutenção dos casamentos se relacionava mais à formação de pares complementares e a um modelo tradicional de casamento, em que a ênfase era colocada na criação dos filhos e estruturação da família, em detrimento da própria conjugalidade

Quality of life and voice after radiotherapy: speech therapy repercussions

BACKGROUND: radiotherapy for head and neck cancer has been important for disease control, both as neo-adjuvant and concomitant to chemotherapy. 5-year survival rates after larynx cancer have increased, justifying the efforts towards rehabilitation of patients` communication and highlighting the importance of the speech-language pathologist in the radiotherapy team. New scientific and therapeutic breakthroughs have turned organ preservation into a strong ally in head and neck cancer treatment. PURPOSE: to show the speech-language-related sequelae, such as changes in vocal and life quality, related to treatment for head and neck tumors, especially those arising after radiotherapy. CONCLUSION: many acute and chronic sequelae, such as hoarseness, odinophagy and aphony, involving difficulties in oral communication and/or swallowing in patients after neck and head radiotherapy treatment, interfering with communication, swallowing, and life quality of patients in a direct manner. The professionals involved with the treatment of this cancer, with the speech-language pathologist among them, through the knowledge on the treatment and its therapeutic weaknesses that jeopardize the vocal quality and life quality of those patients, seek to contribute in the recovery process in order to minimize damages caused by the disease and improving the individual's health condition.TEMA: o tratamento radioterápico do câncer de cabeça e pescoço tem mostrado resultados importantes no controle da doença quando neoadjuvante ou mesmo concomitante à quimioterapia. Pesquisas apontam um aumento da sobrevida após 5 anos de tratamento do câncer de laringe, o que torna necessário e justifica os esforços realizados na reabilitação da comunicação dos pacientes, e destaca a presença do profissional de Fonoaudiologia na equipe de radioterapia. OBJETIVO: descrever as seqüelas com repercussão fonoaudiológica, tais como alterações na qualidade vocal e na qualidade de vida, associadas ao tratamento proposto para tumores de cabeça e pescoço, em especial aquelas originadas após a radioterapia. CONCLUSÃO: Várias seqüelas, agudas e crônicas, como rouquidão, odinofagia e afonia, que envolvem dificuldades na comunicação oral e/ou deglutição dos pacientes após o tratamento radioterápico em cabeça e pescoço, interfere de maneira direta na comunicação, deglutição e qualidade de vida dos pacientes. Os profissionais envolvidos no tratamento desse câncer, dentre eles o fonoaudiólogo, através do conhecimento sobre o tratamento e as fragilidades terapêuticas que comprometem a qualidade vocal e qualidade de vida desses pacientes, busca contribuir no processo de recuperação minimizando os danos causados pela doença e melhorando a condição de saúde do indivíduo

Análise de fluxos metabólicos com substrato isotopicamente marcado (13C-MFA) em S. typhimurium

Linhagens atenuadas de Salmonella têm sido estudadas para produção e veiculação de substâncias com fins terapêuticos. Modelos metabólicos à escala genômica são ferramentas importantes no desenvolvimento de estratégias de engenharia metabólica. Este trabalho teve por objetivo obter dados experimentais para aprimorar o modelo metabólico e aprofundar o conhecimento do metabolismo de S. typhimurium (St). Foram realizados cultivos contínuos à taxa de diluição (D) de 0,24 e 0,48 h-1, utilizando U-13C-glicose como substrato. Aminoácidos da biomassa foram analisados por GC-MS. A análise de fluxos metabólicos permitiu determinar a distribuição de fluxos nas principais vias metabólicas de St. A glicólise foi a via majoritamente utilizada para catabolisar a glicose. As maiores diferenças nos fluxos estimados, para as duas D, verificaram-se nas vias anapleróticas. Sobrepondo os dados de fluxos intracelulares ao modelo metabólico será gerado um modelo mais preciso do metabolismo de S. typhimurium

Burden of disease from COVID-19 and its acute and chronic complications: reflections on measurement (DALYs) and prospects for the Brazilian Unified National Health System

COVID-19 is an acute infectious respiratory distress syndrome (ARDS) caused by the novel coronavirus SARS-CoV-2. The disease is highly communicable and produces mild to severe symptoms, generating a high demand for intensive care and thousands of deaths. In March 2020, COVID-19 was declared a pandemic and has already surpassed five million cases and 300,000 deaths in the world. The natural history of the disease has still not been fully established, hindering the elaboration of effective clinical protocols and preventive measures. Nevertheless, the disease requires a systemic approach, since there is evidence of acute and chronic complications, in addition to the catastrophic effects on the population\u27s mental health. This highlights the need for a methodology that more effectively captures the effect of COVID-19, considering such aspects as severity, duration, and the potential to generate chronic complications that will increase the demands on Brazilian Unified National Health System (SUS). DALYs, or disability-adjusted life years, are thus an extremely useful indictor that adds mortality, an estimate of years of life lost (YLLs), and morbidity, an estimate of years of life lived with disability (YLDs). This article discusses the relevance and difficulties of studying the burden of COVID-19 and its complications in the Brazilian context, highlighting the natural history of the disease and estimating indicators such as YLDs, considering the high burden of disease in planning strategies to deal with the consequences of COVID-19 after the pandemic. The article also discusses the future challenges to deal with the disease in the SUS and the effects on the calculation of DALYs

Impact of oral health conditions on the quality of life of workers

Occupational health has been the scope of numerous studies, primarily due to the concern that the worker should enjoy good working conditions and a satisfactory quality of life. This study seeks to analyze the impact of oral health on the quality of life of workers at a public university using the simplified version of the Oral Health Impact Profile (OHIP-14) and associated factors. A cross-sectional study was conducted with 326 workers who responded the questions of OHIP-14 about self-rated health, oral morbidity, and socioeconomic and demographic questions. Multiple linear regression analysis was performed to verify the association between the independent variables and OHIP-14. About 40% of the impact of oral health on quality of life can be explained by the variables: education level (p = 0,03), age (p = 0,03), reason for visiting a dentist (p = 0,01), oral health perception (p < 0,01) and satisfaction with teeth and mouth (p < 0,01). The use of OHIP-14 can be useful for planning programs and actions focused on health education for occupational health, prioritizing workers with greater psychosocial impacts caused by oral problems.
