Abstract Background Argon plasma coagulation (APC) is a non-tactile ablative therapy that helps to stop rectal bleeding in patients who have developed actinic proctitis after exposure to radiotherapy. This approach seems to be more effective than medications or surgical procedures. Objective To review the literature to verify the effectiveness of APC in the treatment of patients with actinic proctitis induced by radiation therapies. Methods A systematic search was conducted on the following databases: MEDLINE/PubMed, LILACS, SCIELO, and the Cochrane Central Register of Controlled Trials. We identified 81 studies, and 5 of them fulfilled the inclusion criteria. Results In the articles included, a total of 236 patients were evaluated. Most of them were men (67.7%) with a mean age of 66.6 years. Prostate cancer was the main cause of actinic proctitis (67.3%), and control of the bleeding was achieved in 83.3% of the cases, after a mean of 1.67 session of APC. Moreover, 66 patients had complications with the treatment, and rectal pain was the most referred. Conclusions Argon plasma coagulation is a well-tolerated and effective treatment to control rectal bleeding in patients who underwent radiotherapy, and the number of sessions varies from 1 to 2, according to the case.

Resumo Fundamento A classificação funcional da New York Heart Association (NYHA) é o sistema de classificação mais utilizado para a insuficiência cardíaca (IC), enquanto o teste de exercício cardiopulmonar (TECP) é o padrão ouro para a avaliação do estado funcional na IC. Objetivo Analisar a correlação e a concordância entre as classes da NYHA e as variáveis do TECP. Métodos Foram selecionados pacientes com IC com indicação clínica para TECP e fração de ejeção (FE) < 50%. A correlação (coeficiente de Spearman) e a concordância (kappa) entre a classificação da NYHA e as classificações baseadas no TECP foram analisadas. Um valor de p < 0,05 foi considerado significativo. Resultados No total, foram incluídos 244 pacientes no estudo. A idade média foi de 56±14 anos, e a FE média foi de 35,5%±10%. A distribuição de pacientes de acordo com a classificação da NYHA foi a seguinte: classe I (31,2%), classe II (48,3%), classe III (19,2%) e classe IV (1,3%). A correlação (r) entre as classes da NYHA e de Weber foi de 0,489 (p < 0,001), e a concordância foi de 0,231 (p < 0,001). A correlação (r) entre as classes da NYHA e ventilatórias (inclinação da ventilação minuto/produção de dióxido de carbono [VE/VCO2]) foi de 0,218 (p < 0,001), e a concordância foi de 0,002 (p = 0,959). A correlação de Spearman entre as classes da NYHA e do escore TECP foi de 0,223 (p = 0,004), e a concordância kappa foi de 0,027 (p = 0,606). Conclusão Foi identificada uma associação moderada entre as classes da NYHA e de Webber, embora a concordância tenha sido baixa. As classes ventilatórias (inclinação VE/VCO2) e do escore TECP apresentaram uma associação fraca e uma baixa concordância com as classes da NYHA.

Abstract Background The New York Heart Association (NYHA) functional classification is the most commonly used classification system for heart failure (HF), whereas cardiopulmonary exercise testing (CPET) is the gold standard for functional status evaluation in HF. Objective This study aimed to analyze correlation and concordance between NYHA classes and CPET variables. Methods HF patients with clinical indication for CPET and ejection fraction (EF) < 50% were selected. Correlation (Spearman coefficient) and concordance (kappa) between NYHA classification and CPET-based classifications were analyzed. A p < 0.05 was accepted as significant. Results In total, 244 patients were included. Mean age was 56 ± 14 years, and mean EF was 35.5% ± 10%. Distribution of patients according to NYHA classification was 31.2%% class I, 48.3% class II, 19.2% class III, and 1.3% class IV. Correlation (r) between NYHA and Weber classes was 0.489 (p < 0.001), and concordance was 0.231 (p < 0.001). Correlation (r) between NYHA and ventilatory classes (minute ventilation/carbon dioxide production [VE/VCO2] slope) was 0.218 (p < 0.001), and concordance was 0.002 (p = 0.959). Spearman correlation between NYHA and CPET score classes was 0.223 (p = 0.004), and kappa concordance was 0.027 (p = 0.606). Conclusion There was a moderate association between NYHA and Weber classes, although concordance was low. Ventilatory (VE/VCO2slope) and CPET score classes had a weak association and a low concordance with NYHA classes.

RESUMO CONTEXTO: Recentemente foi demonstrada associação entre sintomas do trato urinário inferior entre mães e filhos. No entanto, o papel da constipação funcional neste binômio não é claro. OBJETIVO: Avaliar a disfunção vésico-intestinal entre mães e filhos. MÉTODOS: Estudo transversal de base populacional. As mães e os filhos responderam a um questionário de autorresposta, composto pelos critérios de Roma IV, International Consultation on Incontinence Questionnaire - Overactive Bladder, Dysfunctional Voiding Scoring System e perguntas sociodemográficas. RESULTADOS: Foram estudados 441 pares mãe-filho. A idade média dos filhos foi de 9,1±2,7 anos, sendo 249 (56,5%) do sexo feminino. A idade média das mães foi de 35,7±6,1 anos. A constipação sem sintomas do trato urinário inferior estava presente em 35 (7,9%) crianças e 74 (16,8%) mães. Sintomas do trato urinário inferior isolados estavam presentes em 139 (31,5%) crianças e 92 (20,9%) mães e a disfunção vésico-intestinal ocorreu em 51 (11,6%) crianças e 78 (17,7%) mães. Não houve associação entre sintomas isolados do trato urinário inferior em crianças e sintomas isolados do trato urinário inferior em mães (P=0,31). Na análise univariada, houve associação entre disfunção vésico-intestinal em crianças e disfunção vésico-intestinal em mães (OR=4,8 IC 95% 2,6-9,6; P<0,001) e constipação isolada em crianças e constipação isolada em mães (OR=3,0 IC 95 % 1,4-6,4; P=0,003). Na análise multivariada, mães com disfunção vésico-intestinal foi o único fator de associação independente para disfunção vésico-intestinal em crianças (OR=5,4 IC 95% 2,5-11,6; P<0,001). CONCLUSÃO: Mães com disfunção vésico-intestinal têm maior probabilidade de ter filhos com disfunção vésico-intestinal. A associação entre constipação e sintomas do trato urinário inferior desempenha um papel importante nesta apresentação familiar.

ABSTRACT BACKGROUND: Recently it was shown an association between lower urinary tract symptoms in mothers and their children. However, the role of functional constipation in this binomial is unclear. OBJECTIVE: To evaluate bladder and bowel dysfunction between mothers and children. METHODS: A population-based cross-sectional study. Mothers and their children responded a self-administrated questionnaire composed by Rome IV criteria, International Consultation on Incontinence Questionnaire - Overactive Bladder, Dysfunctional Voiding Scoring System and demographic questions. RESULTS: A total of 441 mother-child pairs was obtained. Children’s mean age was 9.1±2.7 years, with 249 (56.5%) female. Mothers’ mean age was 35.7±6.1 years. Isolated constipation was present at 35 (7.9%) children and 74 (16.8%) mothers. Isolated lower urinary tract symptoms were present in 139 (31.5%) children and 92 (20.9%) mothers and bladder bowel dysfunction occurred in 51 (11.6%) children and 78 (17.7%) mothers. There wasn’t any association between isolated lower urinary tract symptoms in children and isolated lower urinary tract symptoms in mothers (P=0.31). In univariate analysis there were an association between bladder bowel dysfunction in children and bladder bowel dysfunction in mothers (OR=4.8 IC 95% 2.6-9.6, P<0.001) and isolated constipation in children and isolated constipation in mothers (OR=3.0 IC 95% 1.4-6.4, P=0.003). In multivariate analysis mothers with bladder bowel dysfunction was the only independent factor associated with bladder bowel dysfunction in children (OR=5.4 IC 95% 2.5-11.6, P<0.001). CONCLUSION: Mothers with bladder bowel dysfunction are more likely to have a child with bladder bowel dysfunction. Association between these two dysfunctions plays an important role in this familiar presentation.
