Abstract Introduction Scientific studies in Brazil grew around 10.7% compared to previous years. However, the level of quality of evidence has been decreasing. The aim in our study is to examine the meeting abstracts of the Brazilian congress of coloproctology and analyze the level of evidence in trends and variables. Methods A descriptive bibliometric study, working with secondary data to review scientific abstracts in the annals of the coloproctology congress from 2015 to 2019. Results A total of 1756 abstracts of the Brazilian Congress of Coloproctology were analyzed for 5 years (2015-2019). There was a higher trend of abstracts presented with lower levels of evidence (level of evidence 5: 52.3% and 3: 30%), being the majority composed of case reports (49.4%) and retrospective studies (30.4%). The last two years analyzed (2018: 55.2% and 2019: 59.3%) had a predominance above average of case reports. From 2017 to 2019 there was a significant decrease in the number of level 2 evidence studies (18.10%,11.80% and 5.50%), while the number of studies with level 5 evidence showed an increase (45.60%, 56.60% and 61.40%). Statistical analysis occurred in only 17%, with an important decrease for the last two years (2018: 13.6%; 2019: 12.1%). Conclusions Although the data of this study is from the Brazilian coloproctology point of view, they are important for the global scientific community, as they allow a quantitative evaluation of the relative contribution from the level of evidence of Brazilian coloproctology researchers to the scientific scenario.

ABSTRACT Introduction The purpose of this retrospective bibliometric study was to assess the discrepancies between coloproctology surgery meeting abstracts and subsequent full-length manuscript publications. Methods Abstracts presented at the Brazilian Congress of Coloproctology Surgery from 2015 to 2019 were compared with matching manuscript publications. Discrepancies between the abstract and therefore the subsequent manuscript were categorized as major (changes within the purpose, methods, study design, sample size, statistical analysis, results, and conclusions) and minor (changes within the title, authorship, and number of female authors) variations. Results The conversion rate of abstracts in published manuscripts was 6,9% (121 abstracts). There were inconsistencies between the study title (66,1%), authorship (69,5%), study design (3,3%), sample size (39,2%), statistical analysis (24,8%), results (25,6%), and conclusions (12,4%) of manuscripts compared with their corresponding meeting abstracts. Conclusion As changes occur before manuscript publication of coloproctology surgery meeting abstracts, caution should be exercised in referencing abstracts or altering surgical practices based on abstracts content.

Abstract Introduction The presentation of abstracts in a congress is an important step for the dissemination of scientific information. The American Congress of Coloproctology is promoted by the American Society of Colon & Rectal Surgeons (ASCRS), and it is the largest in number of participants within the specialty, followed by the Brazilian Congress of Coloproctology. The present study aims to evaluate variables related to the quality of the scientific production of the abstracts presented in these two events and their conversion rate to published manuscripts. Materials and Methods The present bibliometric study assesses secondary data from the review of abstracts presented in these 2 important conferences in 2016, followed by a research of the publications from these congress presentations. Results The total number of abstracts evaluated was 854. The rate of articles containing statistical analyses was of 73.7% in the American congress, and of 34.1% in the Brazilian congress. Multicentric studies were more prevalent in the American congress (23.1%). Regarding study design, the most common were case reports in the Brazilian (44.8%) congress and retrospective studies in the American congress (67.7%). As for the works presented, the rate of conversion into full manuscripts in the American congress was of 24.2% compared with 10.6% in the Brazilian congress. Most papers from the American congress (93.7%) have citations compared with 68.6% of the other event evaluated. Conclusion The scientific performance demonstrated by the conversion rate of abstracts into publications is below ideal, mainly in relation to the Brazilian meeting; yet, there were significant differences between the two events in terms of the profile of the presentations and several variables analyzed.

ABSTRACT BACKGROUND: Previous studies have shown a relationship between calf circumference (CC) and outcomes in hospitalized patients. AIMS: To investigate the relationship between CC and clinical and nutritional outcomes in older in-patients (OiP) in a surgery ward. METHODS: This was a cross-sectional study with 417 OiP in a surgery ward. Clinical variables, anthropometry, and nutritional screening instruments such as subjective global assessment (SGA), mini nutritional assessment (MNA), and nutritional risk screening (NRS) were used in the investigation. The tests Pearson’s chi-square, Mann-Whitney, Kruskal-Wallis, and Spearman’s coefficient, and multiple linear regression analyses were used to review the factors associated with CC. RESULTS: Lower CC values were found in the age group 80 years and over (p<0.0001), presence of complications (p=0.0269), NRS (p<0.0001), SGA (p<0.0001), and MNA (p<0.0001). Gender (p=0.0011; partial R2=0.01151), age (p=0.0002; partial R2=0.06032), body mass index (p≤0.0001; partial R2=0.40820), and arm circumference (p≤0.0001; partial R2=0.11890) are variables that together were associated with CC. There was also a relationship between SGA (p=0.0166; partial R2=0.00605) and absence of complications during hospitalization (p=0.0047; R2=0.01154) with CC. CONCLUSIONS: Gender, age, body mass index, and arm circumference were jointly associated with CC, in addition to SGA and absence of complications. The CC is a relevant indicator for OiP in the clinical practice.

RESUMO RACIONAL: Estudos anteriores mostraram uma relação entre a circunferência da panturrilha (CP) e desfechos em pacientes hospitalizados. OBJETIVOS: Investigar a relação entre CP e desfecho clínico e nutricional em pacientes idosos hospitalizados (PIH) em uma enfermaria cirúrgica. MÉTODOS: Este foi um estudo transversal com 417 PIH em uma enfermaria de cirurgia. Variáveis clínicas, antropometria e instrumentos de triagem nutricional como avaliação subjetiva global (ASG), mini avaliação nutricional (MAN) e triagem de risco nutricional (NRS) foram utilizados na investigação. Qui-quadrado, Mann-Whitney, Kruskal-Wallis, coeficiente de Spearman e análise de regressão linear múltipla foram usados para analisar os fatores associados a CP. RESULTADOS: Menores valores de CP foram encontrados na faixa etária de 80 anos (p<0,0001), complicações (p=0,0269), risco nutricional pelo NRS (p<0,0001), ASG (p<0,0001) e MAN (p<0,0001). Sexo (p=0,0011; R2 parcial=0,01151), idade (p=0,0002; R2 parcial=0,06032), IMC (p≤0,0001; R2 parcial=0,40820) e circunferência do braço (CB) (p≤0,0001; R2 parcial=0,11890) foram variáveis que juntas estiveram associadas com a CP. Também houve relação entre ASG (p=0,0166; R2 parcial=0,00605) e ausência de complicações durante a internação (p=0,0047; R2= 0,01154) com a CP. CONCLUSÕES: Sexo, idade, IMC e CB associaram-se conjuntamente com CP, ASG e ausência de complicações. CP é um indicador relevante em PIH na prática clínica.

ABSTRACT Introduction: the presentation of research at a congress is an interesting means for scientific dissemination, but only with publication in an indexed journal does the data become accessible and disseminated. The conversion rate in published articles of abstracts presented at congresses is an indicator to assess the scientific quality of those events. The aim of this study is to evaluate bibliometric characteristics of abstracts presented at the Brazilian Congress of Coloproctology and to determine the factors that affect publication rates. Methods: Retrospective evaluation of all abstracts presented at the Brazilian Congresses of Coloproctology from 2015 to 2019. Multiple databases were analyzed to estimate the conversion rate of the presented papers, as well as variables associated with the conversion of abstracts into full manuscripts through bivariate analysis and multivariate variables of these predictors. Results: 1756 abstracts were analyzed. Most studies are retrospective, series or case reports, and even personal experience. The conversion rate was 6.9%. The presence of statistical analysis was twice as high for published abstracts as for unpublished ones. Conclusion: the data presented demonstrate a low scientific productivity of the specialty, since the research carried out is, for the most part, not published as complete manuscripts. The predictors of publication of abstracts were: multicenter studies, studies with statistical analysis, study designs with a higher level of evidence and studies awarded by the congress.

RESUMO Introdução: a apresentação de pesquisas em um congresso é meio interessante para disseminação científica, porém apenas com a publicação em revista indexada é que os dados se tornam acessíveis e disseminados. A taxa de conversão em artigos publicados de resumos apresentados em congressos é um indicador para avaliar a qualidade científica de seus eventos. O objetivo deste estudo é avaliar características bibliométricas dos resumos apresentados no Congresso Brasileiro de Coloproctologia e determinar os fatores que afetam as taxas de publicação. Métodos: avaliação retrospectiva de todos os resumos apresentados nos Congressos Brasileiros de Coloproctologia dos anos de 2015 a 2019. Análise de múltiplas bases de dados para estimar a taxa de conversão dos trabalhos apresentados, assim como variáveis associadas à conversão dos resumos em manuscritos completos através de análises bivariadas e multivariadas desses preditores. Resultados: foram analisados 1756 resumos. A maioria dos estudos são retrospectivos, séries ou relatos de casos e até experiência pessoal. A taxa de conversão foi de 6,9%. A presença de análise estatística foi o dobro para os resumos publicados frente aos não publicados. Conclusão: os dados apresentados demonstram uma baixa produtividade científica da especialidade, já que as pesquisas realizadas não são publicadas, em sua maioria, como manuscritos completos. Os fatores preditores de publicação dos resumos foram: estudos multicêntricos, estudos contendo análise estatística, desenhos de estudo de maior nível de evidência e estudos premiados pelo congresso.

ABSTRACT Objective: This study investigated the nutritional status, 25-hydroxyvitamin D (25OHD), albumin and risk factors associated with complications in patients with foot and ankle fragility fractures. Subjects and methods: Prospective study, developed with patients who suffered fractures due to fragility of the foot and ankle (n = 108); the type of fractured bone, fracture mechanisms and classification were studied and also pseudoarthrosis, treatment, surgical dehiscence, anthropometry, 25OHD and albumin. The Chi-square or Fisher's exact test, Mann-Whitney and Kruskal-Wallis tests were used in the statistical analysis and the multiple logistic regression analysis was used to identify the risk factors associated with complications. Results: The factors that, together, were associated with treatment complications were the level of 25OHD (p = 0.0055; OR = 0.868 [1,152]; 95% CI = 0.786; 0.959 [1.043;1.272]) and diabetes (p = 0.0034; OR = 30,181; 95% CI = 3.087; 295.036). The factors that, together, were associated with the presence of any complication, were age (p = 0.0139; OR = 1.058; 95% CI = 1.011; 1,106) and 25OHD level (p = 0.0198; OR = 0.917; 95% CI = 0.852; 0.986). There was a complication probability above 0.40 associated with lower 25OHD levels (values below 20 ng/mL) and older age (over 50 years). Conclusion: Lower or abnormal levels of 25OHD were associated with pseudoarthrosis, and age and 25OHD were both risk factors for treatment complications in patients with foot and ankle fractures.

RESUMO Contexto A prevalência de pacientes idosos hospitalizados tem crescido substancialmente e impactado os serviços de saúde hospitalar. Desta forma, acredita-se que uma investigação do estado nutricional, associado a situações clínicas variadas em pacientes idosos, poderia contribuir para ações de intervenção hospitalar multidisciplinares e de cuidado nutricional adequadas para esta população. Objetivo Investigar a relação entre dois instrumentos de triagem nutricional em pacientes idosos hospitalizados e comparar variáveis clínicas entre estes dois instrumentos. Métodos Estudo retrospectivo com pacientes idosos hospitalizados (n=277), sendo investigado a concordância entre dois instrumentos de triagem nutricional. Os dados foram analisados pelos testes McNemar, qui-quadrado, Fisher, Mann-Whitney e o coeficiente kappa para a avaliação de concordância. Resultados Houve diferença significativa (P=0,0002) entre as classificações de risco nutricional pelos dois instrumentos de triagem nutricional e concordância moderada (k=0,5430) entre eles. Verificou-se associação entre triagem de risco nutricional e idade (P=0,0255), tempo de internação (P<,0001), sexo (P=0,0365) e doenças (P=0,0001). Houve associação entre a Mini Avaliação Nutricional e tempo de internação (P<0,0001), doenças (P=0,0001) e evolução do peso corporal (P=0,0479). Conclusão Triagem de risco nutricional e a Mini Avaliação Nutricional apresentam concordância moderada para a avaliação de pacientes idosos.

ABSTRACT Background The prevalence of hospitalized elderly patients has grown substantially and has impacted the hospital health services. Thus, it is believed that an investigation of the nutritional status associated with different clinical situations in elderly patients could contribute to multidisciplinary hospital intervention and nutritional care actions suitable for this population. Objective To investigate the relationship between two nutritional screening instruments in hospitalized older patients and to compare clinical variables between these two instruments. Methods Retrospective study with hospitalized older patients (n=277), investigating the agreement between two nutritional screening instruments. The data were analyzed using the McNemar, chi-square, Fisher, Mann-Whitney tests and the kappa coefficient for the agreement assessment. Results There was a significant difference (P=0.0002) between the nutritional risk classifications of the two nutritional screening instruments and moderate agreement (k=0.5430) between them. The association between nutritional risk screening and age (P=0.0255), length of hospital stay (P<0.0001), gender (P=0.0365) and illness (P=0.0001) were assessed. There was an association between Mini Nutritional Assessment and length of stay (P<0.0001), illness (P=0.0001) and body weight evolution (P=0.0479). Conclusion The nutritional risk screening and Mini Nutritional Assessment showed moderate agreement in the assessment of elderly patients.

RESUMO Introdução: recentemente tem-se estudado a variável densidade linfonodal como possível influenciador na sobrevida de pacientes com diagnóstico de câncer de cabeça e pescoço. Objetivo: analisar a relação entre a densidade linfonodal e a sobrevida de pacientes recidivados previamente submetidos a cirurgia de esvaziamento cervical por carcinoma espinocelular de cabeça e pescoço. Método: foram analisados retrospectivamente 71 prontuários pacientes atendidos no Serviço de Cirurgia de Cabeça e Pescoço da Pontifícia Universidade Católica de Campinas que tinham sido submetidos a cirurgia de esvaziamento cervical e apresentaram recidiva tumoral entre os anos de 2006 e 2019. Dados relativos ao paciente e ao tumor tais como: idade, sexo, cor da pele, tabagismo, etilismo, localização do tumor primário, características anatomopatológicas e status linfonodal foram correlacionados ao tempo de sobrevida dos indivíduos. Resultados: encontramos predominância do sexo masculino e a média de idade foi de 59,5 anos. O sítio primário mais frequente foi a cavidade oral seguido da laringe e orofaringe. A taxa de mortalidade foi de 53,52% e a densidade linfonodal média 0,28. Encontramos influência na sobrevida com significância estatística para os parâmetros: densidade linfonodal, número de linfonodos dissecados e acometidos, estadiamento T e N, tipo de tratamento proposto (paliativo ou cirúrgico), presença de margens comprometidas no tumor primário e extravasamento linfonodal. Conclusão: o cálculo da densidade linfonodal em pacientes recidivados após cirurgia de esvaziamento cervical por carcinoma espinocelular de cabeça e pescoço deve ser levado em consideração durante o planejamento terapêutico e na avaliação prognóstica devido à sua direta influencia na sobrevida dos indivíduos.

ABSTRACT Introduction: the variable lymph node ratio has recently been studied as a possible influencer in the survival of patients diagnosed with head and neck cancer. Objective: to analyze the correlation between lymph node density and survival of recurred disease patients previously submitted to cervical dissection surgery due to head and neck squamous cell carcinoma. Method: we retrospectively analyzed 71 medical records of patients treated at the Head and Neck Surgery Service of the Pontifícia Universidade Católica de Campinas who had undergone cervical dissection surgery and presented tumor recurrence between 2006 and 2019. Patient and tumor data such as age, gender, skin color, smoking, alcohol consumption, location of the primary tumor, anatomopathological characteristics and lymph node status were correlated with the survival time. Results: we found a predominance of males and the mean age was 59.5 years. The most frequent primary site was the oral cavity followed by the larynx and oropharynx. The mortality rate was 53.52% and the mean lymph node ratio 0.28. We found influence on survival with statistical significance for the parameters: lymph node ratio, number of dissected and affected lymph nodes, T and N staging, type of treatment proposed (palliative or surgical), presence of compromited margins in the primary tumor and lymph node extravasation. Conclusion: the calculation of lymph node density in patients with recurred disease after cervical dissection surgery by head and neck squamous cell carcinoma should be taken into account during therapeutic planning and prognostic evaluation due to its direct influence on the survival.

Abstract Objective: the aim of this study was to assess weight loss, diet prescribed, and nutritional status in hospitalized patients, as well as their associated factors. Methods: weight loss during hospitalization, nutritional status, disease type, and prescribed diet were investigated in a retrospective study in 621 hospitalized patients. The chi-squared, Fisher's, Mann-Whitney, and Kruskal-Wallis tests were used for statistical analysis. To identify factors associated with weight loss a logistic regression analysis was performed. The significance level adopted for statistical tests was 5 %. Results: patients who experienced weight loss during hospitalization were associated with longer hospital stays (p < 0.0001; OR = 1.052; 95 % CI = 1.030 to 1.073), malnourishment according to the subjective global assessment (p = 0.0358; OR = 1.520; 95 % CI = 1,028 to 2,248), digestive disorders (p = 0.0081; OR = 3.177; 95 % CI = 1.351 to 7.469), and digestive neoplasms (p = 0.0407; OR = 2.410; 95 % CI = 1.038 to 5.597). Conclusion: weight loss during hospitalization was associated with neoplasms, digestive diseases, malnutrition, and length of stay.

Resumen Objetivo: el objetivo de este estudio fue evaluar la pérdida de peso, la dieta prescrita y el estado nutricional de pacientes hospitalizados y sus factores asociados. Métodos: se investigó la pérdida de peso durante la hospitalización, el estado nutricional, el tipo de enfermedad y la dieta prescrita en un estudio retrospectivo de 621 pacientes hospitalizados. Las pruebas del chi cuadrado, Fisher, Mann-Whitney y Kruskal-Wallis se utilizaron para el análisis estadístico. Para identificar los factores asociados con la pérdida de peso se utilizó la regresión logística. El nivel de significación adoptado para las pruebas estadísticas fue del 5 %. Resultados: los casos de pérdida de peso durante la hospitalización se asociaron a las estancias hospitalarias más largas (p < 0,0001; OR = 1,052; IC 95 % = 1,030; 1,073), la desnutrición según la evaluación global subjetiva (p = 0,0358; OR = 1,520; IC 95 % = 1,028; 2,248) los trastornos digestivos (p = 0,0081; OR = 3,177; IC 95 % = 1,351; 7,469) y las neoplasias digestivas (p = 0,0407; OR = 2,410; IC 95 % = 1,038; 5,597). Conclusión: la pérdida de peso durante la hospitalización se asoció con las neoplasias y las enfermedades digestivas, la desnutrición y la duración de la estancia.

Abstract Objectives To evaluate the serrated lesion detection rate in colonoscopy at a specialized clinic and its role as quality criteria for endoscopic examination. Methods This is an observational cross-sectional study with all patients that underwent colonoscopy between October 2018 and May 2019, performed by an experimented physician. A questionnaire was answered before the examination by the patient, and another questionnaire after the colonoscopy was answered by themedical team. All polyps identified were removed and sent to the same pathologist for analysis. Results A total of 1,000 colonoscopies were evaluated. The average age of the patients was 58.9 years old, and most of them were female (60.6%). In 62.5% of the procedures, polyps were removed, obtaining a total of 1,730 polyps, of which 529 were serrated lesions, being 272 sessile serrated lesions (SSL). This data resulted in a serrated lesion detection rate (SDR) of 29.2%, and of 14% when considering only the SSL detection rate (SSLDR). The right colon had higher rates, with 22.3% SDR and 15.3% SSLDR. Screening colonoscopies also presented a higher serrated detection rate, of 20%, followed by diagnostics and follow-up exams. Smoking was the only risk factor associated with higher serrated detection rate. Conclusions The serrated lesion detection rate is higher than the ones already previously suggested and the have the higher rates were stablished in the right colon and on screening exams.

Resumo Objetivos: avaliar o impacto da codetecção de Influenza A (FluA) e Vírus Sincicial Respiratório (VSR) por meio de testes imunocromatográficos rápidos em tempo real, em pacientes menores de 2 anos em hospital público e universitário. Métodos: estudo de coorte retrospectivo foi conduzido para analisar os desfechos clínicos de crianças hospitalizadas com doença respiratória viral com resultados positivos do teste rápido imunocromatográfico para VSR e/ou FluA, de 2013 a 2018. Um modelo de regressão logística foi ajustado para analisar preditores de intubação orotraqueal durante a internação. Resultados: foram analisados 220 casos: RSV (192), FluA (9) eco-detecção (19). A letalidade foi de 1,8% (2 casos) e 88% (194) casos em menores de 1 ano. O tempo médio de internação foi maior nos pacientes com codetecção. As variáveis significativamente associadas à intubação orotraqueal foram: menor idade em meses, comorbidades, codetecção de VSR e Flu-A e pneumonia bacteriana durante a internação. Conclusões: codetecção VSR e FluA foi associada a prognósticos clínicos desfavoráveis. O teste rápido fornece informações importantes a beira-leito, pois os painéis moleculares não são amplamente acessíveis em hospitais públicos. O diagnóstico rápido permite a avaliação e tratamento oportunos.

Abstract Objectives: the aim of this study is to evaluate the impact of co-detection of Flu A and RSV using rapid immunochromatographic tests at the point of care, in pediatric patients under 2 years of age in a general hospital. Methods: a retrospective cohort study was conducted to analyze clinical outcomes in hospitalized infants with viral respiratory disease with positive results of rapid immunochromatographic test for RSV and/or Flu-A, from 2013 to 2018. A logistic regression model was adjusted to analyze predictors of orotracheal intubation during hospitalization. Results: we analyzed 220 cases: RSV (192), Flu-A (9), co-detection (19). Lethality rate was 1.8% (2 cases), and 88% (194) were under 1 year of age. Mean time of hospitalizations was higher in patients with co-detection. Variables significantly associated with orotracheal intubation were: younger age in months, comorbidities, RSV and Flu-A co-detection, and bacterial pneumonia during hospitalization. Conclusions: RSV and Flu-Aco-detection was associated with the least favorable clinical prognoses in this study. Rapid test diagnosis may provide important information at the point of care, because molecular panels are not widely accessible in general hospitals. Rapid diagnosis allows timely evaluation and treatment.

RESUMO CONTEXTO: Pacientes oncológicos podem apresentar alterações gastrointestinais que influenciam o estado nutricional. OBJETIVO: Investigar a ocorrência de alterações gastrointestinais decorrentes do tratamento ambulatorial de quimioterapia, em pacientes oncológicos. MÉTODOS: Num estudo longitudinal retrospectivo, investigou-se o estado nutricional e as alterações gastrointestinais (náuseas, vômito, diarreia, constipação, mucosite, disfagia, xerostomia, inapetência, disgeusia e pirose) de pacientes oncológicos (n=187), em acompanhamento ambulatorial de quimioterapia. Para o estudo dos parâmetros ao longo do tempo, utilizou-se o método das equações de estimação generalizadas (EEG). Também foram utilizados os testes de Kruskal-Wallis, Mann-Whitney e o coeficiente de Spearman, com nível de significância de 5%. RESULTADOS: A maioria dos pacientes era do sexo feminino (63,64%) e a média de idade foi 57,5±12,1 anos. Os sintomas mais frequentes foram náuseas (18,54%); inapetência (18,31%); constipação intestinal (11,58%); diarreia (7,98%); xerostomia (7,59%) e vômito (7,43%). O estado nutricional não apresentou alterações relevantes (P=0,7594). No entanto, observou-se maior prevalência de eutrofia, seguido do sobrepeso e o vômito apresentou diferença significativa (P=0,0211). O sintoma de náusea apresentou diferença significativa com maior prevalência na neoplasia colorretal, quando comparado à neoplasia de mama (P=0,0062); assim como o vômito nas neoplasias de pulmão e colorretal (P=0,0022). E a disfagia, na neoplasia de cabeça e pescoço, quando comparada às demais neoplasias (P<0,001). Houve diferença estatisticamente significante entre o número de consultas médicas e sexo (P=0,0102) e entre disfagia e sexo (P<0,0001). CONCLUSÃO: Os achados encontrados no estudo permitem reforçar a necessidade do acompanhamento de sinais e sintomas, bem como do estado nutricional, de pacientes em acompanhamento ambulatorial de quimioterapia.

ABSTRACT BACKGROUND: Cancer patients may have gastrointestinal changes that influence nutritional status. OBJECTIVE: To investigate the occurrence of gastrointestinal changes resulting from outpatient chemotherapy treatment in cancer patients. METHODS: In a retrospective longitudinal study, the nutritional status and chemotherapy gastrointestinal changes (nausea, vomit, diarrhea, constipation, mucositis, dysphagia, xerostomia, inappetence, dysgeusia and heartburn) in cancer patients (n=187) were investigated in an outpatient follow-up. For the study of the parameters over time, the generalized estimating equation (GEE) method was used. Kruskal-Wallis, Mann-Whitney tests and Spearman coefficient, at a significance level of 5% were also used. RESULTS: The majority of the patients were female (63.64%) and the mean age was 57.5±12.1 years. The most frequent symptoms were nausea (18.54%); inappetence (18.31%); intestinal constipation (11.58%); diarrhea (7.98%); xerostomia (7.59%) and vomiting (7.43%). The nutritional status did not exhibit any relevant changes (P=0.7594). However, a higher prevalence of eutrophy was observed, followed by overweight; vomiting exhibited a significant difference (P=0.0211). The nausea symptom exhibited a significant difference with a higher prevalence of colorectal neoplasia when compared to breast neoplasia (P=0.0062); as well as vomiting in lung and colorectal neoplasias (P=0.0022), and dysphagia, in head and neck neoplasia, when compared to other neoplasms (P<0.001). There was a statistically significant difference between the number of medical appointments and gender (P=0.0102) and between dysphagia and gender (P<0.0001). CONCLUSION: The study findings enhance the need for signs and symptoms follow up, as well as nutritional status follow up of patients undergoing outpatient chemotherapy.

Resumo Contexto A doença venosa crônica (DVC) é a principal causa de úlceras crônicas em membros inferiores. As varizes dos membros inferiores são a causa mais frequente de úlcera venosa (UV). No Brasil, 50,9% das mulheres têm varizes e a prevalência da úlcera chega a 4%. A escleroterapia ecoguiada com espuma (EEE) é uma alternativa de baixo custo para tratamento de varizes de membros inferiores. Objetivos Analisar evolução de portadores de UV tratados com EEE. Métodos Coorte prospectiva e consecutiva em um único serviço. Portadores de UV com veia safena magna (VSM) insuficiente foram acompanhados por 180 dias após EEE. Foram estudadas: qualidade de vida, gravidade da doença, cicatrização e eliminação do refluxo. Foram utilizados questionário Aberdeen, escore clínico venoso e ultrassom Doppler. Resultados Foram tratados 22 pacientes com idade entre 35 a 70 anos. Houve melhora na qualidade de vida, redução da gravidade da doença, e redução dos diâmetros das úlceras (p < 0.001; ANOVA). Houve redução das dimensões em 90,91% das úlceras [intervalo de confiança de 95% (IC95%) 78,9-100%], e cicatrização completa em 77,27% (IC95% 59,76-94,78%). O refluxo foi eliminado em 63,64% (IC95% 43,54-83,74%) das VSM. Homens tiveram maior benefício em qualidade de vida, e mulheres apresentaram mais complicações. Não houve complicações graves. As UV completamente cicatrizadas e as VSM que apresentaram oclusão completa apresentavam dimensões inicialmente menores quando comparadas às das UV não completamente cicatrizadas e das VSM não completamente ocluídas (p < 0,05; Mann-Whitney). Conclusões Os resultados sugerem que EEE foi benéfica para a maioria dos pacientes.

Abstract Background Chronic Venous Disease (CVD) is the main cause of chronic leg ulcers. Varicose veins are the most frequent cause of venous leg ulcers (VLU). 50.9% of Brazilian women have varicose veins and ulcer prevalence is as high as 4%. Ultrasound-guided foam sclerotherapy (UGFS) is a low-cost treatment option for varicose veins. Objectives To analyze UGFS outcomes in patients with VLU. Methods Prospective consecutive single center cohort study. Patients with great saphenous vein (GSV) reflux and VLU were treated and followed-up for 180 days. The following were studied: quality of life (QoL), disease severity, healing, and elimination of GSV reflux. The Aberdeen questionnaire, a venous clinical severity score, and Duplex scanning (DS) results were analyzed. Results 22 patients aged 35 to 70 years were treated. There was improvement in quality of life, disease severity reduced, and ulcer diameter reduced (p < 0.001; ANOVA). 77.27% of VLU healed completely (95%CI: 59.76-94.78%). The dimensions of 20/22 VLU reduced (90.91%; 95%CI: 78.9-100%). GSV reflux was eliminated in 63.64% (95%CI: 43.54-83.74%). Men had greater QoL benefit and women had more complications. There were no severe complications. The VLU that had healed completely at the end of the study were smaller at baseline than those that did not completely heal. The GSV that were completely occluded at the end of the study were smaller at baseline than those that were not completely occluded (p < 0.05; Mann-Whitney). Conclusion The results suggest that most patients benefited from UGFS.

Abstract Objective: to investigate whether the caloric and protein deficits, the diagnosis and the NUTRIC score, behaved as risk factors associated to the survival time. Methods: prospective study with 82 critically ill patients in intensive care unit (ICU), with exclusive enteral nutritional therapy (EENT). We investigated the calorie and protein deficiencies of EENT, the NUTRIC score, and the inflammatory-nutritional index by the C-reactive protein-CRP/albumin. The data were analyzed using the Chi-square, Fisher, Mann-Whitney, Kruskal-Wallis, univariate and multiple Cox regressions and the Kaplan-Meyer method. Results: in the univariate Cox regression, one-year increase in age increased the risk of death by 4.1% (p=0.0009; HR=1.041) and one-day increase with intercurrent events, by 1.8% (p = 0.0485; HR = 1.018). In the multiple Cox regression, the clinical diagnosis (p = 0.0462, HR = 2.091) and the NUTRIC score ≥ 5 (p < 0.0001; HR = 5.740) were the variables that together were associated with the survival time. The critical caloric and protein deficits did not behave as death risk factors in this population. Kaplan-Meier curves showed that the probability of survival in 40 days was 28.1% with clinical diagnosis and 40.2% with surgical diagnosis. The mean survival time with NUTRIC score ≥ 5 was 17.4 days. The probability of survival at 40 days was 72.8% with NUTRIC score < 5 and 6.4% with NUTRIC score ≥ 5. Conclusion: caloric and protein deficits are not risk factors for mortality. Only the diagnosis and the NUTRIC score were considered risk factors associated with the survival time.

Resumen Objetivo: investigar si el déficit calórico y proteico, el diagnóstico y la puntuación nutricional se comportaron como factores de riesgo asociados al tiempo de supervivencia. Métodos: estudio prospectivo con 82 pacientes en estado crítico en la Unidad de Cuidados Intensivos (UCI), con terapia nutricional enteral exclusiva (EENT). Investigamos las deficiencias de calorías y proteínas de EENT, el puntuación NUTRIC y el índice inflamatorio-nutricional por la proteína C-reactiva-CRP / albúmina. Los datos se analizaron utilizando las regresiones de Chi-cuadrado, Fisher, Mann-Whitney, Kruskal-Wallis, univariadas y múltiples de Cox y el método de Kaplan-Meyer. Resultados: en la regresión de Cox univariada, el aumento de un año en la edad aumentó el riesgo de muerte en un 4,1% (p = 0,0009; HR = 1,041) y el aumento de un día con eventos intercurrentes, en un 1,8% (p = 0,0485; HR = 1,018). En la regresión múltiple de Cox, el diagnóstico clínico (p = 0,0462, HR = 2,091) y la puntuación nutricional ≥ 5 (p < 0,0001; HR = 5,740) fueron las variables que juntas se asociaron con el tiempo de supervivencia. Los déficits críticos de calorías y proteínas no se comportaron como factores de riesgo de muerte en esta población. Las curvas de Kaplan-Meier mostraron que la probabilidad de supervivencia en 40 días fue del 28,1% con diagnóstico clínico y del 40,2% con diagnóstico quirúrgico. El tiempo medio de supervivencia con puntuación NUTRIC ≥ 5 fue de 17,4 días. La probabilidad de supervivencia a los 40 días fue del 72,8% con una puntuación nutricional < 5 y del 6,4% con una puntuación NUTRIC ≥ 5. Conclusión: los déficits calóricos y proteicos no son factores de riesgo para la mortalidad. Solo el diagnóstico y la puntuación NUTRIC se consideraron factores de riesgo asociados con el tiempo de supervivencia.
