Progression of valve heart disease in a cohort of patients undergoing renal replacement therapy / Progressão da doença cardíaca valvar em coorte de doentes em terapia renal substitutiva

Abstract Introduction: Cardiovascular disease is an important cause of death among patients with chronic kidney disease (CKD). Valve calcification is a predictor of cardiovascular mortality and coronary artery disease. Objective: To assess heart valve disease frequency, associated factors, and progression in CKD patients. Methods: We conducted a retrospective study on 291 CKD patients at Hospital das Clínicas de Pernambuco. Inclusion criteria were age ≥ 18 with CKD and valve disease, while those on conservative management or with missing data were excluded. Clinical and laboratory variables were compared, and patients were categorized by dialysis duration (<5 years; 5-10 years; >10 years). Statistical tests, including chi-square, Fisher's exact, ANOVA, and Kruskal-Wallis, were employed as needed. Simple and multivariate binary regression models were used to analyze valve disease associations with dialysis duration. Significance was defined as p < 0.05. Results: Mitral valve disease was present in 82.5% (240) of patients, followed by aortic valve disease (65.6%; 86). Over time, 106 (36.4%) patients developed valve disease. No significant association was found between aortic, pulmonary, mitral, or tricuspid valve disease and dialysis duration. Secondary hyperparathyroidism was the sole statistically significant factor for mitral valve disease in the regression model (OR 2.59 [95% CI: 1.09-6.18]; p = 0.031). Conclusion: CKD patients on renal replacement therapy exhibit a high frequency of valve disease, particularly mitral and aortic valve disease. However, no link was established between dialysis duration and valve disease occurrence or progression.

Resumo Introdução: Doenças cardiovasculares são uma causa significativa de morte em pacientes com Doença Renal Crônica (DRC). A calcificação valvar é preditor de mortalidade cardiovascular e doença arterial coronariana. Objetivo: Avaliar a frequência, fatores associados e progressão de valvopatias em pacientes com DRC. Métodos: Coorte retrospectiva com 291 pacientes ambulatoriais no Hospital das Clínicas de Pernambuco. Inclusão: ≥18 anos com DRC e valvopatia; exclusão: tratamento conservador ou dados incompletos. Variáveis clínicas e laboratoriais foram comparadas e categorizadas por tempo de terapia dialítica (TTD): <5 anos, 5-10 anos, >10 anos. Foram aplicados os testes Qui-quadrado, exato de Fisher, ANOVA, Kruskal-Wallis. Associação entre valvopatia e TTD foi avaliada por regressão binária. Significância foi definida como p < 0,05. Resultados: A valvopatia mitral foi encontrada em 82,5% (240) dos casos, seguida da aórtica (65,6%; 86). Houve progressão da doença valvar em 106 (36,4%) pacientes. Não houve associação entre valvopatias aórtica, pulmonar, mitral ou tricúspide e TTD. Hiperparatireoidismo secundário foi a única variável explicativa significativa na regressão para valvopatia mitral (OR 2,59 [IC95%: 1,09-6,18]; p = 0,031). Conclusão: Encontramos alta frequência de valvopatias, especialmente mitral e aórtica, aem pacientes com DRC. Não houve associação entre TTD e valvopatia.

Resiliência alta (RC = 0,01 [0,02-0,11]; p < 0,001 e retornar à cidade natal durante a suspensão das aulas (RC = 0,41 [0,18-0,91]; p = 0,02) foram fatores protetores; e cursar o ciclo clínico foi fator de risco independente (RC = 2,74 [1,26-5,93]; p = 0,01) para depressão de moderada a grave. Conclusão: verificou-se uma alta prevalência de sintomas de ansiedade de moderada e grave, bem como de sintomas depressivos moderados. Um alta proporção dos estudantes apresentou grau de resiliência baixo ou muito baixo.

Abstract: Introduction: The occurrence of pandemics, such as Covid-19, leads to a psychosocial disturbance that can break the limits of the population's coping capacity, generating tensions and anxieties that are expressed in various degrees among those involved. Objective: To analyze the repercussions of the COVID-19 pandemic on the mental health of medical students in the State of Pernambuco. Methods: Cross-sectional analytical study conducted between July and August 2021 with medical students from 11 universities in Pernambuco. The dependent variables analyzed were the scores of anxiety, depression; the independent variables were resilience score, socio-demographic, behavioral characteristics and health conditions. The data were collected through Google Forms. Beck's Anxiety and Depression Inventories, and Wagnild and Young's Resilience Scale were applied. The study was approved by the local ethics committee and informed consent was sought and given. The data were analyzed using SPSS 25, considering as significant a p-value < 0,05. Result: 416 participants were included, the majority (60.9%) of the students were women, the average age was 25 years, and 73.8% of them lived in the municipality of their university. Moderate and severe anxiety symptoms were found in 27.2% and 10.3% of the sample, respectively. Moderate depressive symptoms were observed in 17.8% of the students. About 25% of the sample reported a low or very low degree of resilience. High resilience (Odds Ratio [OR] 0.18 [0.08-0.41]; p <0.001) and psychological support prior to the pandemic (OR 0.36 [0.14-0.95]; p = 0 .04) were protective factors and attending the clinical cycle (2nd-3rd year) was an independent risk factor (OR 1.95 [1.07-3.55]; p = 0.02) for moderate to severe anxiety. High resilience (OR 0.01 [0.02-0.11]; p < 0.001 and returning to one's hometown during the suspension of classes (OR 0.41 [0.18-0.91]; p = 0.02) were protective factors and attending the clinical cycle was an independent risk factor (OR 2.74 [1.26-5.93]; p = 0.01) for moderate to severe depression. Conclusion: We found a high prevalence of moderate and severe anxiety symptoms, as well as moderate depressive symptoms. A high proportion of students demonstrated a low or very low degree of resilience.

Telogen Effluvium and COVID-19: a case and a brief review of literature / Eflúvio Telógeno e COVID-19: um caso e uma breve revisão de literatura

COVID-19 is a new disease that has brought a great impact on global morbidity and mortality. There have been increasingly frequent reports of persistent symptoms and/or clinical manifestations attributed to COVID-19 after the acute phase of the disease. In this article, we present a case of post-COVID-19 telogen effluvium in a 39-year-old hypertensive and obese patient who looked for medical attention due to massive hair loss. Previous history of moderate COVID-19 4 months ago. After investigation and exclusion of other possible causes of telogen effluvium well established in the literature, the condition was attributed to the previous episode of COVID-19. Persistent fever, the cytokine storm, and the entire immunological cascade of COVID-19 can lead to apoptosis of the keratinocytes of the hair follicles, initiating the catagen phase early followed by the telogen phase with a consequent capillary release. Late symptoms possibly secondary to COVID-19 should receive attention and interest from the medical and scientific community. As it is a new disease, whose late consequences are not yet fully known/elucidated, careful observation and careful clinical follow-up of these patients are recommended (AU)

A COVID-19 é uma doença nova que vem provocando grande impacto na morbimortalidade mundial. Relatos de persistência de sintomas e/ou manifestações clínicas atribuídas à COVID-19 após a fase aguda da doença tem sido cada vez mais frequentes. Neste artigo, apresentamos um caso de eflúvio telógeno pós COVID-19 em um paciente de 39 anos, hipertenso e obeso, que procurou atendimento médico devido à queda volumosa de cabelos. Histórico prévio de COVID-19 moderada há 4 meses. Após investigação e exclusão de outras possíveis causas de eflúvio telógeno bem estabelecidas na literatura o quadro foi atribuído ao episódio prévio de COVID-19. É possível que a febre persistente, a tempestade de citocinas e toda a cascata imunológica da COVID-19 possam levar à apoptose dos queratinócitos dos folículos capilares, iniciando, assim, precocemente a fase catágena seguida pela fase telógena com consequente liberação capilar. Sintomas tardios possivelmente secundários à COVID-19 devem ser alvo de atenção e interesse da comunidade médica e científica. Por se tratar de uma doença nova, cujas consequências tardias ainda não se encontram completamente conhecidas/ elucidadas, recomenda-se a observação atenta e o seguimento clínico criterioso desses pacientes (AU)

ICD indication in hypertrophic cardiomyopathy: which algorithm to use?

SUMMARY OBJECTIVE: This study aimed to evaluate the agreement in the indication of implantable cardioverter-defibrillators in patients with Hypertrophic cardiomyopathy, as per the 2014 European Society of Cardiology and 2020 American Heart Association recommendations, and evaluate fragmented QRS as a predictor of cardiovascular outcome. METHODS: Retrospective cohort with 81 patients was evaluated between 2019 and 2021. Patients with hypertrophic cardiomyopathy ≥16 years old were included. Exclusion criteria include secondary myocardiopathy and follow-up <1 year. Kappa coefficient was used to determine the agreement. Survival and incidence curves were determined by Kaplan-Meier method. A p<0.05 was considered significant. RESULTS: The fragmented QRS was identified in 44.4% of patients. There were no differences between patients with and without fragmented QRS regarding clinical parameters, echocardiography, fibrosis, and sudden cardiac death risk. During follow-up of 4.8±3.4 years, there was no sudden cardiac death, but 20.6% patients with implantable cardioverter-defibrillator had at least one appropriate shock. Three of the seven appropriate shocks occurred in European Society of Cardiology low- to moderate-risk patients. Three shocks occurred in moderate-risk patients and four in American Heart Association high-risk patients. Overall recommendations agreement was 64% with a kappa of 0.270 (p=0.007). C-statistic showed no differences regarding the incidence of appropriate shock (p=0.644). CONCLUSION: sudden cardiac death risk stratification algorithms present discrepancies in implantable cardioverter-defibrillator indication, both with low accuracy.

Association between hyperuricemia and hypertension: a case-control study

SUMMARY OBJECTIVE: The aim of this study was to evaluate the association between hyperuricemia and systemic arterial hypertension. METHODS: This was a case-control study where individuals aged >18 years were included, who were divided into hypertensive and non-hypertensive groups, excluding those with incomplete information in medical records or with the chronic kidney disease epidemiology collaboration <60 mL/min/1.73 m³. Systemic arterial hypertension was categorized as a dependent variable, while the independent variables were hyperuricemia (i.e., primary variable), sex, education, the practice of physical activity, alcoholism, smoking, diabetes mellitus, chronic kidney disease, a family history of systemic arterial hypertension, age, isolated hyperlipidemia, and mixed hyperlipidemia. Statistical analysis included the univariate and multivariate data analysis, performed by adjusting the logistic regression models using the software R (R Core Team [2018]). RESULTS: Out of 103 patients evaluated, 75 patients were included in this study. In hypertensive patients, hyperuricemia was more frequent (p=0.029), being present in 18.9% individuals. In the univariate analysis, a statistically significant association was found between hyperuricemia and systemic arterial hypertension (OR 10.9; 95%CI 1.29-1420.0; p=0.023); however, in the multivariate analysis, when adjustment was made for age, the only control variable that persisted in the model, this association ceased to be significant (OR 8.5; 95%CI 0.87-1157.0; p=0.070). CONCLUSIONS: There was no independent association between hyperuricemia and systemic arterial hypertension. The latter was associated with diabetes mellitus, chronic kidney disease, and age.

Antifungal efficacy of amphotericin b in candida albicans endocarditis therapy: systematic review

Abstract Introduction: Although it is the most common agent among the fungal causes of endocarditis, Candida albicans endocarditis is rare. Objective: To evaluate the efficacy of amphotericin B in the treatment of C. albicans endocarditis beyond a systematic review. Data search: Articles in English, Spanish and Portuguese, conducted in the following databases: MEDLINE, LILACS, IBECS and SciELO, in humans and published in the last 25 years. Study selection: Observational studies, clinical trials, and case series providing data on the amphotericin B use in patients with a C. albicans endocarditis diagnosis without age limitations. Data synthesis: From the initial search (n=79), 25 articles were fully evaluated, of which 19 were excluded for meeting one or more exclusion criteria, remaining five articles (two observational studies and three case series). Patients using amphotericin B demonstrated improvement in survival rates, and its main use was in association with the surgical method as well as with caspofungin association. Conclusion: Literature lacks evidence to conclude about efficacy and safety of amphotericin B in the treatment of fungal endocarditis. Randomized clinical trials are necessary to provide better evidence on the subject.

Angioedema, endothelium, ACE2, and bradykinin - interrelationships in COVID-19: a case report / Angioedema, Endotélio, ECA2 e bradicinina - inter-relações na COVID-19: um relato de caso

ABSTRACT: COVID-19 is a new disease, whose several atypical clinical manifestations began to be observed with the evolution of the pandemic, and have been investigated to understand the pathophysiology of the disease. In this article, the objective is to describe a case of angioedema in COVID-19, considered an atypical manifestation, and rarely described in the literature. The case is of a 55-year-old patient who sought medical attention for a complaint of intermittent fever for four days. On the seventh day, he manifested angioedema in the left zygomatic projection and the right subpalpebral region. The patient had no history of angioedema earlier in life. The following day, he presented a regression of the angioedema concerning the previous day. After this period, the patient progressed well and became asymptomatic. The RT-PCR laboratory test performed on the first days of manifesting symptoms was positive for SARS-CoV-2. We correlate the onset of angioedema with the possible endotheliitis present in the disease, which has been evidenced by the observation of severe endothelial injury associated with the intracellular presence of the virus in several histopathological studies of patients with COVID-19. Also, possible deregulation of the Kininogen-Kallikrein-Kinin System (KKKS) could explain this manifestation, as SARS-CoV-2 binds to the ACE2 receptor, which is responsible for degrading kinins, such as bradykinin. (AU)

RESUMO: A COVID-19 é uma doença nova, cujas diversas manifestações clínicas atípicas começaram a ser observadas com a evolução da pandemia e foram investigadas com o objetivo de compreender a fisiopatologia da doença. Neste artigo, o objetivo é descrever um caso de angioedema no COVID-19, considerado manifestação atípica e raramente descrito na literatura. O caso é de um paciente de 55 anos que procurou atendimento médico por uma queixa de febre intermitente há quatro dias. No sétimo dia, manifestou angioedema na projeção zigomática esquerda e na região subpalpebral direita. Não tinha histórico de apresentar angioedema. No dia seguinte, ele apresentou regressão do angioedema em relação ao dia anterior. Após esse período, o paciente progrediu bem e tornou-se assintomático. O teste laboratorial de RT-PCR realizado nos primeiros dias de manifestação dos sintomas foi positivo para SARS-CoV-2. Correlacionamos o início do angioedema com a possível endotelite presente na doença, o que foi evidenciado pela observação de lesão endotelial grave associada à presença intracelular do vírus em vários estudos histopatológicos de pacientes com COVID-19. Além disso, uma possível desregulação do sistema Cininogênio-Calicreína-Cinina poderia explicar essa manifestação, já que o SARS-CoV-2 se liga ao receptor ACE2, responsável pela degradação de cininas, como a bradicinina.

Aspirin with or without statin in the treatment of endotheliitis, thrombosis, and ischemia in coronavirus disease

Abstract INTRODUCTION: In the genesis of coronavirus disease (COVID-19), there is a process of endotheliitis associated with thrombotic changes, no studies have reported the use of acetylsalicylic acid (ASA) as a possible therapeutic approach. Statins could potentiate the ASA therapy. METHODS: This is a series of 14 cases with a laboratory-confirmed diagnosis of COVID-19. All patients underwent the ASA therapy. Those who had risk factors for vascular disease also underwent the high-potency statin therapy. When symptoms were totally or practically resolved, patients were discharged and advised to continue medications for a complementary time, according to the clinical evolution of each patient. RESULTS: The mean age of monitored patients was 48.6 years. A total of 78.6% patients presented with at least one comorbidity, which could have contributed as a risk factor for a poor prognosis in the evolution of COVID-19. Four patients had secondary bacterial infections; three patients needed hospitalization. None of the cases progress to stage III, and all patients had remission of symptoms, with 100% survival. CONCLUSIONS: the process of endothelial dysfunction in COVID-19 involves disseminated thrombosis, initially microvascular and later expansion into larger vessels. ASA could act as a secondary prophylaxis and prevent thrombosis from developing and reaching stage III of the disease. As this was a case series, we cannot provide definitive conclusions; however, this study allows us to formulate hypotheses and support clinical trials to evaluate benefits of the ASA therapy in the treatment of COVID-19.

GLA Gene Mutation in Hypertrophic Cardiomyopathy with a New Variant Description: Is it Fabry's Disease? / Mutação do Gene GLA na Cardiomiopatia Hipertrófica com Descrição de Nova Variante: É Doença de Fabry?

Abstract Background: Fabry disease (FD) is an X-linked lysosomal storage disorder caused by mutations in the alpha galactosidase A gene (GLA) that lead to the enzymatic deficiency of alpha galactosidase (α-Gal A), resulting in the accumulation of globotriaosylceramide (Gb3) and globotriaosylsphingosine (lyso-Gb3), causing multiple organ dysfunctions. Objective: To perform GLA gene screening in a group of patients with echocardiographic diagnosis of hypertrophic cardiomyopathy (HCM). Methods: a cross-sectional study was conducted with HCM patients from a university hospital. Patients with coronary artery disease and valvulopathies were excluded. Mutation analysis of the GLA gene was performed. In male subjects, the analysis was performed after evidence of low α-Gal A activity. Results: 60 patients with echocardiographic diagnosis of HCM were included. Age ranged from 12 to 85 years and 60% were women. Mean myocardial fibrosis percentage on MRI was 10.7 ± 13.1% and mean ventricular thickness was18.7 ± 6.7 mm. Four patients had the following GLA gene mutations: c.967C>A (p.Pro323Thr), not yet described in the literature; c.937G>T (p.Asp313Tyr); and c.352C>T (p.Arg118Cys). All patients had normal levels of lyso-Gb3 and non-ischemic myocardial fibrosis on magnetic resonance imaging; one patient had proteinuria and one patient had ventricular tachycardia. Conclusion: in this study, the frequency of mutation in the GLA gene in patients with HCM was 6.7%. A novel mutation in exon 6 of the GLA gene, c.967C>A (p.Pro323Thr), was identified. Patients with HCM may have GLA mutations and FD should be ruled out. Plasma (lyso-Gb3) levels do not seem to be sufficient to attain a diagnosis and organ biopsy should be considered.

Resumo Fundamento: A doença de Fabry (DF) é uma doença de armazenamento lisossômico ligada ao cromossomo X, devido a mutações no gene da alfa galactosidase A (GLA), levando a deficiência enzimática de alfa-galactosidase (α-Gal A) e acúmulo de globotriaosilceramida (Gb3) e globotriaosilsulfingosina (liso-Gb3), causando disfunção de múltiplos órgãos. Objetivo: realizar a triagem do gene GLA em um grupo de pacientes com diagnóstico ecocardiográfico de cardiomiopatia hipertrófica (CMH). Métodos: estudo transversal realizado com pacientes com CMH em um hospital universitário. Pacientes com doença arterial coronariana e valvopatias foram excluídos. Foi realizada análise de mutação do gene GLA. Em indivíduos do sexo masculino, a análise foi realizada após evidência de baixa atividade de α-Gal A. Resultados: Foram incluídos 60 pacientes com diagnostico ecocardiográfico de CMH. A idade variou de 12 a 85 anos e 60% eram mulheres. O percentual médio de fibrose miocárdica na RM foi 10,7 ± 13,1% e a espessura ventricular média foi 18,7 ± 6,7 mm. Quatro pacientes tinham as seguintes mutações do GLA: c.967C>A (p.Pro323Thr), ainda não descrita na literatura; c.937G>T (p.Asp313Tyr); e c.352C>T (p.Arg118Cys). Todos os pacientes apresentavam níveis normais de liso-Gb3 e fibrose miocárdica não isquêmica na ressonância magnética; um paciente apresentou proteinúria; um paciente apresentou taquicardia ventricular. Conclusão: Neste estudo, a frequência de mutação no gene GLA em pacientes com CMH foi 6,7%. Uma nova mutação no exon 6 do gene GLA, c.967C>A (p.Pro323Thr), foi identificada. Pacientes com CMH podem ter mutações do GLA e a DF deve ser excluída. Os níveis plasmáticos de (liso-Gb3) não parecem ser suficientes para fazer um diagnóstico e biópsia de órgãos deve ser considerada.

Prevalence of depression and anxiety and their association with cardiovascular risk factors in Northeast Brasil primary care patients

SUMMARY BACKGROUND: Depression and anxiety disorders (DAD) are the most prevalent mental health conditions worldwide. Among the adult population served in basic care, it is estimated that depression affects about 14.3% of these individuals worldwide, and between 21.4% and 31% in Brasil. Anxiety affects up to 33.7% of the population during their lifetimes. OBJECTIVES: estimate the prevalence proportions of DAD among patients in a municipality in Northeast Brasil and study the association between DAD and cardiovascular risk factors. METHODS: a cross-sectional study with the medical records of patients from primary care centers in Jaboatão dos Guararapes, Pernambuco. Patients aged ≥ 18 years and regularly followed-up were included. Exclusion criteria: a history of traumatic brain injury, alcohol or drug abuse, previous stroke, medical conditions or medications that mimic DAD symptoms. Subjects were divided into two groups depending on the presence or absence of DAD, and cardiovascular risk factors were compared between groups. RESULTS: A total of 1030 subjects were initially included, of whom 215 (20%) were excluded. No-DAD subjects had more history of myocardial infarction and alcoholism. The prevalence of depression was 10.3%, anxiety disorder was 27.1%, and mixed DAD represented 4.5%. There was a significant association between DAD and hypertension (OR = 2.11; 95%CI: 1.16 -3.84; p=0.01), obesity (OR = 4.47; 95%CI: 1.74 -11.46; p=0.002), and hyperlipidemia (OR = 3.88; 95%CI: 1.81-8.3; p<0.001). CONCLUSION: DAD were associated with an increased risk for arterial hypertension, obesity, and hyperlipidemia.

RESUMO INTRODUÇÃO: Transtornos de ansiedade e depressão (TAD) são os distúrbios psiquiátricos mais comuns no mundo. Dentre a população adulta atendida na atenção básica, estima-se que a depressão afete cerca de 14,3% desses indivíduos mundialmente, podendo este valor ir de 21,4% a 31% no Brasil. A ansiedade afeta até 33,7% da população durante sua vida. OBJETIVO: Estimar a prevalência de TAD em pacientes da atenção primária em um município do Nordeste brasileiro e associar sua ocorrência com fatores de risco cardiovasculares. MÉTODOS: Um estudo de coorte transversal com análise de prontuário de pacientes atendidos em unidades de saúde da família de Jaboatão dos Guararapes, Pernambuco. Foram incluídos pacientes ≥18 anos e acompanhados regularmente. Critérios de exclusão: história de trauma crânio encefálico, abuso de álcool e drogas, acidente vascular cerebral prévio, doenças ou medicações que mimetizem sintomas de TAD. Os indivíduos foram divididos em dois grupos, a depender da presença ou não de TAD, e os fatores de risco cardiovascular foram comparados entre os grupos. RESULTADOS: De um total de 1.030 indivíduos recrutados, 215 (20%) foram excluídos. O grupo não TAD apresentou mais história de infarto do miocárdio e etilismo. A prevalência de depressão foi de 10,3%, a de ansiedade foi de 27,1% e a associação entre os dois foi de 4,5%. Houve associação significativa entre TAD e hipertensão (OR = 2,11; IC95: 1,16-3,84; p=0,01), obesidade (OR = 4,47; IC95%: 1,74-11,46; p=0,002) e dislipidemia (OR = 3,88; IC95%: 1,81-8,3; p<0,001). CONCLUSÃO: TAD estão associados com maior risco de hipertensão arterial, obesidade e dislipidemia.

Long-term traumatic and asymptomatic aorto-right atrial fistula

Abstract Aorto-atrial fistulas due to cardiac trauma are rare, and survivors require immediate surgical correction. Here, we report a case of an aorto-right atrial fistula due to penetrating trauma after a 16-year evolution, which developed symptoms of acute coronary syndrome and was treated with myocardial revascularization and correction of the aorto-cameral fistula.

Obstructive sleep apnea and quality of life in elderly patients with a pacemaker / Apneia obstrutiva do sono e qualidade de vida em idosos portadores de marca-passo

ABSTRACT Objective: To evaluate quality of life in elderly patients with obstructive sleep apnea (OSA) who have a pacemaker. Methods: This was a cross-sectional study involving elderly patients (≥ 60 years of age) with a pacemaker. The dependent variable was quality of life, as evaluated with the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Sociodemographic and clinical parameters, including anxiety and depression (Hospital Anxiety and Depression Scale score), as well as the presence of OSA (defined as an apnea-hypopnea index ≥ 15 events/h), were analyzed as independent variables. Patients with cognitive/neurological deficits or decompensated heart failure were excluded. Results: We evaluated 72 patients, 17 (23.6%) of whom presented OSA. Of those 17 patients, 9 (52.9%) were male. The mean age was 72.3 ± 9.3 years. A diagnosis of OSA was not associated with gender (p = 0.132), age (p = 0.294), or body mass index (p = 0.790). There were no differences between the patients with OSA and those without, in terms of the SF-36 domain scores. Fourteen patients (19.4%) presented moderate or severe anxiety. Of those 14 patients, only 3 (21.4%) had OSA (p = 0.89 vs. no OSA). Twelve patients (16.6%) had moderate or severe depression. Of those 12 patients, only 2 (16.6%) had OSA (p = 0.73 vs. no OSA). Conclusions: In elderly patients with a pacemaker, OSA was not found to be associated with quality of life or with symptoms of anxiety or depression.

RESUMO Objetivo: Avaliar a qualidade de vida em idosos portadores de marca-passo e apneia obstrutiva do sono (AOS). Métodos: Estudo de corte transversal com idosos (idade ≥ 60 anos) portadores de marca-passo cardíaco. A variável dependente foi qualidade de vida, avaliada por meio do Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Dados sociodemográficos e clínicos foram analisados como variáveis independentes, entre os quais ansiedade e depressão (por meio da Hospital Anxiety and Depression Scale), assim como presença de AOS (definida como um índice de apneia-hipopneia ≥ 15 eventos/h). Pacientes com déficits cognitivos/neurológicos ou descompensação cardíaca foram excluídos. Resultados: A amostra foi composta por 72 pacientes, 17 dos quais (23,6%) apresentaram AOS - 9 homens (52,9%). A média de idade foi de 72,3 ± 9,3 anos. Não houve associações de presença de AOS com sexo (p = 0,132), idade (p = 0,294) e índice de massa corpórea (p = 0,790). Não foram observadas diferenças dos domínios do SF-36 entre os grupos com e sem AOS. Em relação à ansiedade, 14 pacientes (19,4%) apresentaram sintomas moderados ou graves, dos quais apenas 3 (21,4%) tinham AOS (p = 0,89 vs. sem AOS). No tocante à depressão, 12 pacientes (16,6%) apresentaram sintomas moderados ou graves, dos quais 2 (16,6%) tinham AOS (p = 0,73 vs. sem AOS). Conclusões: Nesta amostra em idosos portadores de marca-passo, a presença de AOS não foi associada a qualidade de vida e sintomas de ansiedade e depressão.

Fatores associados ao aumento da vulnerabilidade de participantes de pesquisa / Factors linked to the increased vulnerability of research subjects / Factores asociados al aumento de la vulnerabilidad de los participantes de la investigación

Resumo Trata-se de estudo de corte transversal cujo objetivo foi avaliar a prevalência de fatores associados ao aumento da vulnerabilidade de participantes de pesquisas. Foram entrevistados 116 pacientes e 18 médicos. Entre os pacientes, 15% eram analfabetos, 27% desconheciam o motivo do seu internamento e 45% não sabiam qual tratamento estavam recebendo. Do total da amostra, 43% procediam de zona rural e 70% haviam cursado, no máximo, ensino fundamental, fatores que tornam essa população especialmente vulnerável. Os percentuais de acerto em questões relacionadas à compreensão do termo de consentimento livre e esclarecido e de prescrição médica foram, respectivamente, 12% e 7%. Entre os médicos, 44% não conheciam todas as pesquisas realizadas na enfermaria pela qual eram responsáveis e 17% afirmaram que a permanência hospitalar de pacientes que participam de pesquisas é maior. É elevada a prevalência de fatores que aumentam a vulnerabilidade de participantes em pesquisas médicas.

Abstract A cross-sectional study was carried out that aimed to assess the prevalence of factors associated with the increased vulnerability of research subjects. A total of 116 patients and 18 doctors were interviewed. A proportion of 15% of patients were illiterate, 27% did not know the reason for their hospitalization and 45% did not know what treatment they were receiving. Of the total sample, 43% were from rural areas and 70% had at most an elementary level education, factors that make this population especially vulnerable. The percentage of correct answers on issues related to the understanding of free and informed consent and prescriptions were 12% and 7%, respectively. Among the doctors, 44% were not aware of all the research projects being carried out in the ward for which they were responsible, and 17% said that the hospital stays of patients participating in research were longer. The prevalence of factors that increased the vulnerability of subjects in medical research was high.

Prevalência de manifestações atípicas em portadores de Síndrome Coronariana Aguda / The prevalence of atypical presentations in patients with Acute Coronary Syndrome

INTRODUÇÃO: A característica anginosa da dor torácica tem sido identificada como o dado com maior poder preditivo para Síndrome Coronariana Aguda (SCA), entretanto as características da dor torácica nem sempre se assemelham com aquelas classicamente descritas. OBJETIVO: Avaliar a prevalência de manifestações atípicas em pacientes internados com Síndrome Coronariana Aguda, correlacionar tais apresentações com os dados clínicos e de exames complementares e compará-las com as manifestações típicas. METODOS: Estudo de corte transversal.A classificação de dor torácica de Diamond foi utilizada para caracterização da dor (variável dependente). As frequências das variáveis independentes (fatores de risco para Doença Arterial Coronária - DAC, alterações eletrocardiográficas, laboratoriais, ecocardiográficas e angiográficas) foram calculadas e comparadas entre os grupos: 1) Dor típica, 2) Dor atípica e 3) Dor não anginosa, estabelecendo-se o valor de p<0,05 como estatisticamente significante. RESULTADOS: Foram avaliados 127 pacientes dos quais 16 (12,6%) apresentavam dor típica, 54(42,5%) dor atípica e 57 (44,9%) dor não anginosa. Os grupos não apresentaram diferença estatisticamente significante em relação aos fatores de risco para DAC; aos níveis dos marcadores de necrose miocárdica; às alterações ecocardiográficas e angiográficas. Pacientes do grupo 3 apresentaram frequência significativamente maior de arritmias ventriculares que aqueles dosgrupos 1 e 2 (21,1 x 6,7 x 5,7%, respectivamente; p=0,041). CONCLUSÃO: As frequências de dor torácica de características atípicas e não anginosas foram elevadas e significativamente maiores que a de dor torácica de características típicas. Não foi observado associação estatisticamente significante entre as características da dor torácica e perfil clínico e dos exames complementares...

INTRODUCTION: Anginal symptoms of chest pain have been identified as the greatest predictive power for Acute Coronary Syndrome (ACS), however chest pain symptoms do not always resemble those, which are classically described. OBJECTIVES: To assess the prevalence of atypical presentations in patients admitted to hospital with Acute Coronary Syndrome, to correlate these presentations with clinical data and additional tests and to compare them with typical presentations. METHODOS: This was a cross-sectional study. The Diamond classification of chest pain was used to characterise chest pain (dependent variable). The frequencies of the independent variable (risk factors for Coronary Artery Disease - (CAD), electrocardiographic, laboratory, echocardiographic and angiographic changes) were calculated and compared between each group: 1) Typical chestpain, 2) Atypical chest pain and 3) Non-anginal chest pain. A p-value <0.05 was established as statistical significance. RESULTS: A total of 127 patients were assessed, of whom 16(12.6%) presented typical chest pain, 54 (42.5%) atypical chest pain and 57 (44.9%) non-anginal chest pain. The groups didnot present any statistically significant differences regarding Coronary Artery Disease risk factors, markers for myocardialnecrosis, and echocardiographic and angiographic changes. Patients in group 3 presented a significantly higher frequency of ventricular arrhythmias than those in groups 1 and 2 (21.1 x6.7 x 5.7%, respectively; p=0.041). CONCLUSION: The frequencies of atypical and non-anginal chest pain were higherand significantly greater than those of typical chest painsymptoms. No statistically significant association was observed between the chest pain symptoms and the clinical profile and the additional tests...

Análise do reprocessamento de cateteres de hemodinâmica em um capital brasileira / Analysis reprocessing hemodynamic catheters in a brazilian state capital

Fundamentos: O reprocessamento de dispositivos de uso único (DUU) é realizado tanto em países desenvolvidos como naqueles em desenvolvimento, face ao elevado custo desses materiais. No Brasil, estudos sobre o reprocessamento de DUU são escassos. Objetivo: Avaliar a prevalência e as condições do reprocessamento de cateteres de hemodinâmica na cidade do recife, PE - Brasil. Métodos: Estudos transversal. Foram avaliados quatro hospitais da rede pública e seis da rede privada, e entrevistados 10 enfermeiros e 82 técnicos de enfermagem dos setores de hemodinâmica. Para a coleta dos dados utilizou-se um questinário. resultados: Todos os hospitais pesquisados reprocessam cateteres. Apenas um deles realiza todas as etapas do reprocessamento na própria instituição. Na maioria dos hospitais, os cateteres são reutilizados, em média, quatro vezes. Observou-se significativa divergência nas respostas fornecidas pelos enfermeiros e técnicos de enfermagem, o que reflete a falta de padronização das técnicas utilizadas no reprocessamento. A maioria dos profissionais já detectou fraturas e tortuosidades nos cateteres reprocessados. A preparação enzimática é utilizada por mais de 80% dos técnicos para a limpeza dos cateteres. Em relação à limpeza do lúmen, não houve uniformidade entre as respostas fornecidas pelos profissionais. Embora a maioria dos profissionaios utilize a água da torneira para o enxágue dos cateteres, as técnicas utilizadas são bastantes diversificadas. Testes para verificação de materiais pirogênicos não são executados em todos os materiais reprocessado. Conclusão: Todos os serviços avaliados reprocessam cateteres de hemodinâmica, entretanto as técnicas utilizadas não são padronizadas.

Background: Reprocessing single-use devices (SUDs) is a practice found in the developed countries and in developing countries as well, due to the high costs of these items. In Brazil, there are few studies on reprocessing hemodynamic catheters. Objective: To evaluated the prevalence and conditions for reprocessing hemodynamic catheters in the city of Recife, Pernambuco State, Brazil. Methods: This cross-sectional study evaluates four government hospitals, and six private hospitals, interviewing 10 nurses and 82 nursing technicians working in the hemodynamics sectors. Data was gathered through a questionnaire. Results: All the hospitals surveyed reprocessing stages in-house. at most of these hospitals, catheters are reused four times on average. Significant differences in the replies provided by the nurses and nursing technicians were noted, reflecting a lack of standardization in the reprocessing techiques. Most of these practitioners had already detected fractures and twists in reprocessed catheters. Enzyme preparations were used by more than 80% of the technicians for cleaning the catheters, with no uniformity on cleaning the lumen in their replies. Although most of the used tap water to rinse the catheters, the techniques used varied greatly. Tests to check pyrogenic materials were not performed on all the reprocessed materials. Conclusion: All of the evaluated hospital units reprocessed hemodynamic catheters, although the techniques used are not standardized.

Pre-hospital attitudes adopted by patients faced with the symptoms of acute myocardial infarction / Atitudes pré-hospitalares adotadas por pacientes frente aos sintomas de infarto agudo do miocárdio / Actitudes prehospitalarias adoptadas por pacientes frente a los síntomas de infarto agudo del miocardio

This case series aimed to evaluate the behavior adopted by patients during the pre-hospital phase of acute myocardial infarction (AMI). A total of 115 AMI sufferers with ST-segment elevation were evaluated. The chi-square and Fisher's exact tests were applied. The individuals that did not associate the symptoms with cardiovascular disease most often attributed them to the following sources: gastrointestinal (38 percent), musculoskeletal (29.7 percent), food and/or medication poisoning (8.5 percent) and arising from the respiratory apparatus (6.3 percent). The proportion of major outcomes and of patients that arrived in the emergency department after 12 hours was higher among women, individuals with monthly income of up to one minimum wage, those who used analgesics and did not associate the symptoms with cardiovascular disease. It was found that individuals in unfavorable socioeconomic conditions, who interpreted the symptoms incorrectly, arrived later at the emergency department and had worse intra-hospital outcomes.

Esta série de casos teve o objetivo de avaliar as condutas adotadas pelos pacientes, durante a fase pré-hospitalar do infarto agudo do miocárdio (IAM). Avaliaram-se 115 indivíduos portadores de IAM, com supradesnivelamento do segmento ST. Foi aplicado o teste qui-quadrado e o teste exato de Fisher. Os indivíduos que não associaram os sintomas à doença cardiovascular atribuíram, mais frequentemente, às seguintes origens: gastrointestinal (38 por cento), osteomuscular (29,7 por cento), intoxicação alimentar e/ou medicamentosa (8,5 por cento) e decorrentes do aparelho respiratório (6,3 por cento). A proporção de desfechos maiores e de pacientes que chegaram à emergência após 12 horas foi mais elevada entre mulheres, indivíduos com renda mensal de até um salário mínimo, que usaram analgésicos e não associaram os sintomas à doença cardiovascular. Constatou-se que indivíduos em condições socio-conômicas desfavoráveis, que interpretaram os sintomas de forma incorreta, chegaram mais tardiamente à emergência e apresentaram piores desfechos intra-hospitalares.

Esta serie de casos tuvo el objetivo de evaluar las conductas adoptadas por los pacientes durante la fase prehospitalaria del infarto agudo del miocardio (IAM). Se evaluaron 115 individuos portadores de IAM con el segmento ST supradesnivelado. Fue aplicada la prueba Chi-cuadrado y la prueba exacta de Fisher. Los individuos que no asociaron los síntomas a la enfermedad cardiovascular la atribuyeron más frecuentemente a los siguientes orígenes: gastrointestinal (38 por ciento), osteomuscular (29,7 por ciento), intoxicación alimentar y/o medicamentosa (8,5 por ciento) y provenientes del aparato respiratorio (6,3 por ciento). La proporción de resultados más graves y de pacientes que llegaron a la emergencia después de 12 horas fue más elevada entre mujeres, individuos con renta mensual de hasta un salario mínimo, que usaron analgésicos y no asociaron los síntomas a la enfermedad cardiovascular. Se constató que individuos en condiciones socioeconómicas desfavorables, que interpretaron los síntomas de forma incorrecta, llegaron más tarde a la emergencia y presentaron peores resultados intrahospitalarios.
