Assessing the level of evidence of presented studies at the Brazilian Congress of Coloproctology

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.

IS CALF CIRCUMFERENCE ASSOCIATED WITH CLINICAL AND NUTRITIONAL OUTCOME IN OLDER PATIENTS?

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.

Lower 25-hydroxyvitamin D (25OHD) levels, diabetes and age are associated with foot and ankle fracture treatment complications.

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.

Discrepancies of abstracts presented in coloproctology congresses and later publish as full manuscripts: a Brazilian perspective

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.

An American and Brazilian perspective on abstracts presented in coloproctology conferences converted into published manuscripts

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.

The Impact of Clinical and Craniofacial Changes on the Surgical Outcomes of Lateral Pharyngoplasty in the Treatment of Obstructive Sleep Apnea.

Objective To verify if maxillomandibular retrusion, obesity, and increased neck circumference are factors of worse surgical prognosis for lateral pharyngoplasty in apneic patients. Materials and Methods We evaluated 53 patients with obstructive sleep apnea who underwent lateral pharyngoplasty. Clinical evaluation was performed before the surgical procedure and included the measurement of body mass index (BMI) in kg/m 2 , neck circumference in centimeters, and a clinical evaluation of the facial profile obtained through the natural position of the oriented head. The polysomnographic evaluation was performed with at a minimum of 6 months after surgery, and polysomnographic results were correlated with the preoperative clinical data. Results The mean age of the patients was 38.8 years; the mean BMI was of 29.28kg/m 2 , and 84.9% of the sample was composed of men and 15.1% of women. There was a significant reduction in the mean value of the main respiratory parameters verified by polysomnography, such as apnea-hypopnea index (AHI) from 31.60 events per hour to 8.15 ( p < 0.001); NadirO 2 went from 81% to 85% ( p = 0.002) and mean oxyhemoglobin saturation from 94% to 95% ( p = 0.024). It was also observed that the greater the maxillomandibular retrusion, the lower the mean reduction of the AHI after surgery. The increase in neck circumference proved to be a factor associated with the surgical outcome, and for each 1-cm decrease in the neck circumference, the chance of surgical success increased 1.2-fold. Conclusion Lateral pharyngoplasty is an efficient surgical obstructive sleep apnea treatment. The lower the neck circumference measurement, the greater the chances of surgical success, and clinically evaluated maxillomandibular retrusion can reduce the magnitude of improvement in respiratory parameters after lateral pharyngoplasty in apneic patients.

Lower 25-hydroxyvitamin D (25OHD) levels, diabetes and age are associated with foot and ankle fracture treatment complications

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.

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.

Prognostic analysis of lymph node ratio of patients with disease recurrence previously submitted to cervical dissection surgery for head and neck cancer.

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.

AGREEMENT BETWEEN NUTRITIONAL SCREENING INSTRUMENTS IN HOSPITALIZED OLDER PATIENTS.

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.

Factors associated with patient weight loss and prescribed diet during hospitalization / Factores asociados a la pérdida de peso de los pacientes y la dieta prescrita durante la hospitalización

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. (AU)

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. (AU)

Evaluation of the serrated lesions detection rate and its role as a colonoscopy quality criteria

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. (AU)

Prognosis of hospitalized children under 2 years of age with co-detection of influenza A and respiratory syncytial virus at the healthcare facility / Prognóstico de crianças hospitalizadas menores de 2 anos com codetecção de influenza A e vírus sincicial respiratório no local de atendimento

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 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.

Factors associated with patient weight loss and prescribed diet during hospitalization.

INTRODUCTION: 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.

INTRODUCCIÓN: 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.

Alterações gastrointestinais durante o acompanhamento nutricional de pacientes oncológicos em acompanhamento ambulatorial de quimioterapia / Gastrointestinal changes during nutritional follow-up of cancer patients undergoing outpatient chemotherapy

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: 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.
