RESUMO

In this study, B. cereus was detected in dialysis fluids within international parameters (ultrapure - maximum limit of 0.1 CFU/mL for heterotrophic bacteria count) by analyzing the pellet obtained through the centrifugation method. We also investigated the ability of the B. cereus isolate to form a biofilm at different temperatures, the production of virulence factors, and the susceptibility to commercial antimicrobial agents. This study demonstrated a high ability of B. cereus to persist in the hemodialysis system, which can be explained by its broad ability to produce a biofilm at 25 °C, its relevant production of virulence factors, such as ß-hemolysin, lecithinase and cereulide, and its important resistance pattern to antimicrobial drugs. In conclusion, these new findings expand the understanding that this microorganism should not be neglected and new methods for tracking it should be considered.

RESUMO

Background: Peripheral artery disease (PAD) has high prevalence and is associated with high risk of cardiovascular events. Surgical or endovascular intervention is necessary in chronic limb-threatening ischemia. Objectives: To evaluate the distribution of open and endovascular revascularizations in different regions of Brazil, analyzing the health system costs and mortality related to these procedures. Methods: A descriptive, cross-sectional, observational, epidemiological study was carried out to evaluate open and endovascular surgeries performed on the SUS public healthcare system in Brazil, from 2010 to 2020. Data were collected from the SUS Department of Informatics (Datasus). Results: Over the period analyzed, 83,218 admissions for open and endovascular surgeries were registered, with a total cost of R$ 333,989,523.17. There were more hospital admissions for percutaneous procedures (56,132) than for conventional surgery (27,086). Most of the procedures (83%) were performed in the country's Southeast and South regions, while the North region had the lowest number of procedures. Over the period evaluated, there was a decreasing trend for open procedures and an increasing trend for endovascular procedures. The average hospital stay was shorter for endovascular procedures (5.3 days) than for open surgery (10.2 days). The analysis of mortality related to these procedures revealed a higher rate of in-hospital mortality associated with open revascularization than with endovascular (5.24% vs. 1.56%). Conclusions: Endovascular techniques constituted the primary approach for revascularization treatment in critical limb-threatening ischemia, with a lower in-hospital mortality rate and shorter hospital stay when compared to open surgeries.

RESUMO

Identificar o perfil clínico e epidemiológico de Homens que fazem Sexo com Homens (HSH) que vivem com HIV/Aids. Estudo transversal realizado com 67 HSH que vivem com HIV/Aids. A coleta de dados clínicos e sociodemográficos foi realizada a partir de prontuários clínicos de um serviço de saúde. A idade dos participantes variou de 18 a 64 anos, a maioria fazia uso regular da TARV, apresentou linfócitos T CD4+ inicial e atual <500 células/mm³, carga viral inicial <100.000 cópias/ ml e atual <50 cópias/ml. Foi observada uma diferença estatística entre pacientes que não faziam uso regular da TARV e os que faziam uso regular desta, pois os que faziam uso regular apresentaram menos infecções oportunistas (p=0,046). Pacientes que apresentaram T CD4+ inicial ≥500 células/mm3 tiveram menos comorbidades (p=0,007) e infecções oportunistas (p=0,003). Também, pacientes que apresentaram carga viral inicial<100.000 cópias/ml tiveram menos infecções oportunistas (p=0,021). As comorbidades (anemia, caquexia, diarreia, tabagismo e depressão), coinfecções (sífilis, HPV e hepatite B) e infecções oportunistas (candidose oral, dermatite persistente e tosse persistente) foram prevalentes em HSH com HIV. Também, foi observado que a TARV tem um efeito protetor importante em relação a proteção contra infecções oportunistas.

To identify the clinical and epidemiological profile of Men who have Sex with Men (MSM) living with HIV / AIDS. Cross-sectional study carried out with 67 MSM living with HIV / AIDS. The collection of clinical and sociodemographic data was performed from clinical records of a health service. The age of the participants varied from 18 to 64 years, most of them used ART regularly, had initial and current CD4 + T lymphocytes <500 cells / mm³, initial viral load <100,000 copies / ml and current <50 copies / ml. A statistical difference was observed between patients who did not use ART regularly and those who used it regularly, as those who used it regularly had fewer opportunistic infections (p = 0.046). Patients who had an initial CD4 + T ≥500 cells / mm3 had fewer comorbidities (p = 0.007) and opportunistic infections (p = 0.003). Also, patients who had an initial viral load <100,000 copies / ml had fewer opportunistic infections (p = 0.021). Comorbidities (anemia, cachexia, diarrhea, smoking and depression), co-infections (syphilis, HPV and hepatitis B) and opportunistic infections (oral candidiasis, persistent dermatitis and persistent cough) were prevalent in MSM with HIV. In addition, it was observed that ART has an important protective effect in relation to protection against opportunistic infections.

ABSTRACT In this study, B. cereus was detected in dialysis fluids within international parameters (ultrapure - maximum limit of 0.1 CFU/mL for heterotrophic bacteria count) by analyzing the pellet obtained through the centrifugation method. We also investigated the ability of the B. cereus isolate to form a biofilm at different temperatures, the production of virulence factors, and the susceptibility to commercial antimicrobial agents. This study demonstrated a high ability of B. cereus to persist in the hemodialysis system, which can be explained by its broad ability to produce a biofilm at 25 °C, its relevant production of virulence factors, such as β-hemolysin, lecithinase and cereulide, and its important resistance pattern to antimicrobial drugs. In conclusion, these new findings expand the understanding that this microorganism should not be neglected and new methods for tracking it should be considered.

RESUMO

RESUMO Contexto A doença arterial obstrutiva periférica apresenta alta prevalência, sendo associada a elevado risco de eventos cardiovasculares. A intervenção cirúrgica ou endovascular faz-se necessária na isquemia crítica do membro. Objetivos Avaliar a distribuição de realização de revascularizações abertas e endovasculares nas diferentes regiões do Brasil, analisando os custos para o sistema de saúde e a mortalidade relacionada a esses procedimentos. Métodos Foi realizado um estudo epidemiológico observacional transversal descritivo para avaliar as cirurgias abertas e endovasculares realizadas no sistema público de saúde do Brasil entre 2010 e 2020. Os dados foram coletados através do Departamento de Informática do SUS (Datasus). Resultados No período analisado, foram registradas 83.218 internações para realização de cirurgias abertas e endovasculares, com um custo total de R$ 333.989.523,17. Houve predominância das internações para os procedimentos percutâneos (56.132) em relação aos cirúrgicos convencionais (27.086). As Regiões Sudeste e Sul concentraram a maior parte do total de procedimentos realizados no país (83%), enquanto a Região Norte foi a que apresentou a menor taxa de internação. Observou-se uma tendência decrescente para os procedimentos abertos, e uma tendência crescente para os endovasculares. A média de permanência hospitalar foi menor nos procedimentos endovasculares (5,3 dias) em relação aos abertos (10,2 dias). Além disso, notou-se uma maior taxa de mortalidade hospitalar relacionada à revascularização aberta em relação à endovascular (5,24% versus 1,56%). Conclusões As técnicas endovasculares consistiram em uma abordagem dominante no tratamento cirúrgico da isquemia crítica, apresentando menor taxa de mortalidade hospitalar e menor tempo de internação quando comparada às cirurgias abertas.

RESUMO

INTRODUÇÃO: As alterações impostas pela doença renal e por seu tratamento interferem negativamente na qualidade de vida dos indivíduos com doença renal crônica. A atividade física é relatada como uma alternativa terapêutica nesta população, porém a maioria dos pacientes submetidos à hemodiálise apresentam baixos níveis de atividade física. OBJETIVO: verificar a correlação entre a atividade física e qualidade de vida em indivíduos com doença renal crônica em hemodiálise. MÉTODOS: Este estudo é observacional, analítico, descritivo e quantitativo, desenvolvido em uma das Unidades de Hemodiálise da região Noroeste do Rio Grande do Sul, Brasil, na atenção clínica terciária, durante o período de novembro de 2018 a fevereiro de 2019. Foram incluídos indivíduos maiores de 18 anos e em tratamento hemodialítico por doença renal crônica há mais de três meses, pertencentes ao serviço de hemodiálise. Os critérios de exclusão foram os indivíduos com diagnóstico de doença renal aguda; aqueles que apresentaram aparentemente dificuldades em compreender, responder ou que não realizaram completamente os instrumentos de avaliação propostos (qualidade de vida e pedômetros), indivíduos que no momento da avaliação não apresentaram condições clínicas estáveis. A coleta de dados foi realizada pela análise dos prontuários clínicos e eletrônicos e entrevista semiestruturada. Utilizou-se avaliação pelos pedômetros e pelo questionário Kidney Disease and Quality of Life Short-Form-KDQOL-SFTM. Análises de modelagem por regressão foram realizadas para testar a associação entre o número de passos/dia e os desfechos avaliados RESULTADOS: Foram incluídos na amostra 40 pacientes, destes, 70% são homens, com média de idade de 59,9 ± 13,0 anos. Na correlação entre atividade física e qualidade de vida, o número de passos/dia teve correlação significativa com as dimensões sintomas e problemas (r=0,523;p=0,003), efeitos da doença (r=0,458; p=0,010), função sexual (r=0,361;p=0,050), sono (r=0,357;p=0,049), função física (r=0,617;p=<0,001), papel físico (r=0,504;p=0,004), dor (r=0,496; p=0,005), bem estar emocional (r=0,407; p=0,023), papel emocional (r=0,435;p=0,014), função social (r=0,522;p=0,003), energia/fadiga (r=0,436;p=0,014) e composição física (r=0,598;p=<0,001). As variáveis idade, índice de massa corporal, tempo de hemodiálise e sexo não apresentaram correlação com o número de passos/dia. CONCLUSÃO: Houve correlação positiva entre atividade física e qualidade de vida, ou seja, quanto maior a média de número de passos/dia melhor a qualidade de vida de indivíduos em hemodiálise.

INTRODUCTION: The changes imposed by kidney disease and its treatment negatively affect the quality of life of individuals with kidney disease. Physical activity is reported as a therapeutic alternative in this population; however, most patients undergoing hemodialysis have low levels of physical activity. OBJECTIVE: To verify the correlation between physical activity and quality of life in individuals with chronic kidney disease undergoing hemodialysis. METHODS: This study is observational, analytical, descriptive, and quantitative developed in one of the Hemodialysis Units in the Northwest region of Rio Grande do Sul, Brazil, in tertiary clinical care, during the period from November 2018 to February 2019. Individuals over 18 years old and undergoing hemodialysis for chronic kidney disease for more than three months; belonging to the hemodialysis service. Data collection was performed by analyzing clinical and electronic medical records and semi-structured interviews. Evaluation using pedometers and the Kidney Disease and Quality of Life Short FormKDQOL-SFTM questionnaire was used. Regression modeling analyzes were performed to test the association between the number of steps/ day and the evaluated outcomes. RESULTS: 40 (Forty) patients were included in the sample, of which 70% are men, with a mean age of 59.9 ± 13.0 years. In the correlation between physical activity and quality of life, the number of steps / day had a significant correlation with the dimensions symptoms and problems (r=0,523;p=0,003), effects of the disease (r=0,458; p=0,010), sexual function (r=0,361;p=0,050), sleep (r=0,357;p=0,049), physical function (r=0,617;p=<0,001), physical role (r=0,504;p=0,004), pain (r=0,496; p=0,005), emotional well-being (r=0,407; p=0,023), emotional role (r=0,435;p=0,014), social function (r=0,522;p=0,003), energy / fatigue (r=0,436;p=0,014) and physical composition (r=0,598;p=<0,001). The sample profile variables did not correlate with the number of steps/day. CONCLUSION: There was a positive correlation between physical activity and quality of life; that is, the higher the average number of steps/day, the better the quality of life of individuals undergoing hemodialysis.

RESUMO

OBJECTIVE: Evaluate the effect of watching comedy movies as a complementary practice during dialysis on levels of anxiety, depression, quality of life, stress, laboratory findings and intra-dialysis complications. METHODS: A randomized clinical trial was conducted involving the practice of presenting comedy movies during dialysis. The primary outcome was depression. The secondary outcomes were anxiety, quality of life, stress, laboratory findings and intra-dialysis complications.ResultsTwenty-six patients were in the control group and 35 were in the experimental group. Significant intra-group differences [6.0 to 3.0 (p <0.001) and 8.0 to 4.0 (p <0.001), respectively] and inter-group differences [5.0 vs. 3.0 (p = 0.016) and 7.0 vs. 4.0 (p = 0.017), respectively] were found regarding anxiety and depression scores, with improvements in the experimental group. The experimental group was also less likely to have intra-dialysis complications, such as hypertension (p = 0.003) and headache (p = 0.020), and reported significant improvements in different domains of quality of life [symptoms/problems (p = 0.003); effects of the disease (p = 0.008); pain (p = 0.027); general health state (p = 0.004); and social function (p = 0.036)]. No significant differences were found in salivary cortisol or the results of the biochemical exams, with the exception of a reduction in hematocrit in the control group.ConclusionsThe proposed complementary practice was associated with reductions in anxiety and depression scores and intra-dialysis complications (hypertension and headache) as well as improvements in quality of life in patients with chronic kidney disease.

RESUMO

OBJETIVOS: Descrever um caso de lesão anal causada por infecção pelo papilomavírus humano em uma mulher vivendo com HIV/aids. DESCRIÇÃO DO CASO: Mulher de 35 anos, diagnosticada há cinco anos com HIV, relatou prurido e sangramento anal, dor ao defecar e visualização de pequenas verrugas na região perianal. Atendida em um serviço de atenção especializada, foi submetida a exame clínico com inspeção visual, o qual revelou condiloma na região perianal. O exame histopatológico confirmou a presença de displasia de grau moderado a acentuado associado a alterações compatíveis com infecção pelo papilomavírus humano. A paciente foi encaminhada para exérese da lesão. No início dos sintomas, a paciente ainda não fazia uso da terapia antirretroviral e apresentava a maior carga viral do HIV de seu histórico laboratorial, com 2.951 cópias/ml. Também havia passado por estresse emocional e estava com infecções genitais recorrentes pelo vírus Herpes simplex. Esses fatores podem ter contribuído para o desenvolvimento do condiloma anal. CONCLUSÕES: A possibilidade de que a infecção pelo HIV possa alterar a história da infecção pelo HPV alerta para que nessas situações sejam adotadas estratégias rigorosas de rastreamento através do exame citológico, tanto do colo do útero como da região anal.

AIMS: To describe a case of anal lesion caused by human papillomavirus (HPV) infection in a woman living with HIV/AIDS. CASE DESCRIPTION: A 35-year-old woman, diagnosed with HIV five years ago, reported pruritus ani, anal bleeding, painful defecation, and presence of small warts in the perianal region. The patient was seen at a specialized care center and was subjected to clinical examination with visual inspection, which revealed perianal condyloma. Histopathological examination confirmed the presence of moderate to severe dysplasia associated with HPV-compatible changes. The anal lesion was excised. At the onset of the symptoms, the patient was not on antiretroviral therapy and her HIV viral load was at its highest (2,951 copies/mL) compared with her previous laboratory tests. She had gone through emotional stress and presented with recurrent genital herpes simplex virus infections. These factors may have predisposed her to the development of anal condyloma. CONCLUSIONS: Since HIV infection may alter the history of HPV infection, it is important that screening strategies include cytological analysis of both the cervix and the anal region.

RESUMO

INTRODUCTION:: Obesity refers to the accumulation of fatty tissues and it favors the occurrence of oxidative stress. Alternatives that can contribute to body weight reduction have been investigated in order to reduce the production of reactive oxygen species responsible for tissue damage. The aim of the current study was to assess whether the oxidant and antioxidant markers of obese women before and after bariatric surgery were able to reduce oxidative damage. METHOD:: We have assessed 16 morbidly obese women five days before and 180 days after the surgery. The control group comprised 16 non-obese women. Levels of thiobarbituric acid-reactive substances, carbonylated proteins, reduced glutathione and ascorbic acid were assessed in the patients' plasma. RESULTS:: Levels of lipid peroxidation and protein carbonylation in the pre-surgical obese women were higher than those of the controls and post-surgical obese women. Levels of reduced glutathione in the pre-surgical obese women were high compared to the controls, and declined after surgery. Levels of ascorbic acid fell in the pre--surgical obese women compared to the control and post-surgical obese women. CONCLUSION:: Body weight influences the production of reactive oxygen species. Bariatric surgery, combined with weight loss and vitamin supplementation, reduces cellular oxidation, thus reducing tissue damage.

Resumo Introdução: Na obesidade, verifica-se um acúmulo de tecido adiposo, o que favorece a ocorrência de estresse oxidativo. A fim de diminuir a produção das espécies reativas que levam a danos teciduais, buscam-se alternativas que contribuam para a redução do peso corporal. Este estudo avaliou se os marcadores oxidantes e antioxidantes de obesas antes e após cirurgia bariátrica reduziram o dano oxidativo. Método: Foram avaliadas 16 mulheres obesas mórbidas cinco dias antes e 180 dias após o procedimento cirúrgico. O grupo controle constituiu-se de 16 mulheres não obesas. Os níveis das substâncias reativas ao ácido tiobarbitúrico, das proteínas carboniladas, da glutationa reduzida e do ácido ascórbico foram avaliados no plasma dessas pacientes. Resultados: Os níveis de lipoperoxidação e da carbonilação de proteínas nas obesas pré-cirúrgicas eram mais elevados quando comparados ao controle e às obesas pós-cirúrgicas; os níveis de glutationa reduzida eram maiores nas obesas pré-cirúrgicas em comparação ao controle e diminuíram após a cirurgia; os níveis de ácido ascórbico eram menores nas obesas pré-cirúrgicas em relação ao controle e às obesas pós-cirúrgicas. Conclusão: Observou-se que a massa corporal influenciou na produção das espécies reativas. A cirurgia bariátrica, somada à perda de peso e à suplementação vitamínica, diminui a oxidação celular e, com isso, reduz os danos teciduais.
