Cost-utility analysis of outpatient parenteral antimicrobial therapy (OPAT) in the Brazilian national health system.

BACKGROUND: Outpatient parenteral antimicrobial therapy (OPAT) has been used for decades in different countries to reduce hospitalization rates, with favorable clinical and economic outcomes. This study assesses the cost-utility of OPAT compared to inpatient parenteral antimicrobial therapy (IPAT) from the perspective of a public university hospital and the Brazilian National Health System (Unified Health System -SUS). METHODS: Prospective study with adult patients undergoing OPAT at an infusion center, compared to IPAT. Clinical outcomes and quality-adjusted life year (QALY) were assessed, as well as a micro-costing. Cost-utility analysis from the hospital and SUS perspectives were conducted by means of a decision tree, within a 30-day horizon time. RESULTS: Forty cases of OPAT (1112 days) were included and monitored, with a favorable outcome in 97.50%. OPAT compared to IPAT generated overall savings of 31.86% from the hospital perspective and 26.53% from the SUS perspective. The intervention reduced costs, with an incremental cost-utility ratio of -44,395.68/QALY for the hospital and -48,466.70/QALY for the SUS, with better cost-utility for treatment times greater than 14 days. Sensitivity analysis confirmed the stability of the model. CONCLUSION: Our economic assessment demonstrated that, in the Brazilian context, OPAT is a cost-saving strategy both for hospitals and for the SUS.

Desfechos assistenciais na implantação do protocolo minimalista de implante transcateter de válvula aórtica / Care outcomes in the implementation of the minimalist protocol for transcatheter aortic valve implantation

INTRODUÇÃO: A abordagem minimalista no implante transcateter da válvula aórtica tornou-se ideal tecnicamente pela redução das comorbidades pré-operatórias e consequentemente, recuperação mais rápida e com menos riscos associados comparados com a cirurgia de troca de válvula aórtica convencional. O conceito de Implante Transcateter de Válvula Aórtica minimalista é definido pela simplificação dos aspectos técnicos como anestesias local/sedação consciente, acesso percutâneo, ecotranstorácico, monitorização em unidade de pós-procedimento anestésico, associados à assistência multidisciplinar, visando simplificar os aspectos da atenção ao paciente, sem perder o foco na segurança da assistência e na obtenção dos melhores desfechos clínicos, assim como na diminuição da internação e custos hospitalares. OBJETIVO: Descrever desfechos assistenciais obtidos na implantação do protocolo minimalista. MÉTODOS Estudo retrospectivo, unicêntrico, realizado em uma Instituição de grande porte especializada em Cardiologia do município de São Paulo. Os dados agregados foram extraídos do laboratório de hemodinâmica da sessão de intervenção Percutânea em Valvopatias, no período de janeiro de 2022 a maio 2023. RESULTADOS Dos 106 procedimentos de Implante Transcateter de Válvula Aórtica realizados no laboratório de hemodinâmica, 94,3% foram minimamente invasivos associados a ações multiprofissional de acordo com o protocolo estabelecidos pelo Heart Team da sessão de Intervenção em Valvopatias. CONCLUSÃO: O Enfermeiro é o profissional essencial na gestão de recursos de materiais específicos, recursos humanos especializados e na mobilização da equipe em assistir e garantir a assistência segura no procedimento minimamente.

Improvement in left ventricular dysfunction after surgical correction of mitral regurgitation.

OBJECTIVE: To evaluate whether left ventricular end-systolic (ESD) diameters < or = 51mm in patients (pt) with severe chronic mitral regurgitation (MR) are predictors of a poor prognosis after mitral valve surgery (MVS). METHODS: Eleven pt (aged 36 +/- 13 years) were studied in the preoperative period (pre), median of 36 days; in the early postoperative period (post1), median of 9 days; and in the late postoperative period (post2), mean of 38.5 +/- 37.6 months. Clinical and echocardiographic data were gathered from each pt with MR and systolic diameter > or = 51 mm (mean = 57 +/- 4mm) to evaluate the result of MVS. Ten patients were in NYHA Class III/IV. RESULTS: All but 2 pt improved in functional class. Two pt died from heart failure and infectious endocarditis 14 and 11 months, respectively, after valve replacement. According to ejection fraction (EF) in post2, we identified 2 groups: group 1 (n=6), whose EF decreased in post1, but increased in post2 (p=0.01) and group 2 (n=5), whose EF decreased progressively from post1 to post2 (p=0.10). All pt with symptoms lasting < or = 48 months had improvement in EF in post2 (p=0.01). CONCLUSION: ESD > or = 51 mm are not always associated with a poor prognosis after MVS in patients with MR. Symptoms lasting up to 48 months are associated with improvement in left ventricular function.

Healthcare-associated infective endocarditis: a case series in a referral hospital from 2006 to 2011.

BACKGROUND: Healthcare-associated infective endocarditis (HCA-IE), a severe complication of medical care, shows a growing incidence in literature. OBJECTIVE: To evaluate epidemiology, etiology, risk factors for acquisition, complications, surgical treatment, and outcome of HCA-IE. METHODS: Observational prospective case series study (2006-2011) in a public hospital in Rio de Janeiro. RESULTS: Fifty-three patients with HCA-IE from a total of 151 cases of infective endocarditis (IE) were included. There were 26 (49%) males (mean age of 47 ± 18.7 years), 27 (51%) females (mean age of 42 ± 20.1 years). IE was acute in 37 (70%) cases and subacute in 16 (30%) cases. The mitral valve was affected in 19 (36%) patients and the aortic valve in 12 (36%); prosthetic valves were affected in 23 (43%) patients and native valves in 30 (57%). Deep intravenous access was used in 43 (81%) cases. Negative blood cultures were observed in 11 (21%) patients, Enterococcus faecalis in 10 (19%), Staphylococcus aureus in 9 (17%), and Candida sp. in 7 (13%). Fever was present in 49 (92%) patients, splenomegaly in 12 (23%), new regurgitation murmur in 31 (58%), and elevated C-reactive protein in 44/53 (83%). Echocardiograms showed major criteria in 46 (87%) patients, and 34 (64%) patients were submitted to cardiac surgery. Overall mortality was 17/53 (32%). CONCLUSION: In Brazil HCA-IE affected young subjects. Patients with prosthetic and native valves were affected in a similar proportion, and non-cardiac surgery was an infrequent predisposing factor, whereas intravenous access was a common one. S. aureus was significantly frequent in native valve HCA-IE, and overall mortality was high.

Adult rhabdomyoma of the larynx.

Introduction Rhabdomyoma is a rare benign tumor derived from skeletal muscles. Laryngeal rhabdomyomas are even rarer, with only approximately 40 reported cases in world literature. Laryngeal rhabdomyomas usually are seen as masses covered by mucosa. They are often solitary asymptomatic tumors, but symptoms such as hoarseness can occur. The radiologic features are usually those typical of benign neoplasms, showing well-delineated borders. The differential diagnoses for laryngeal masses include cysts, laryngoceles, and benign and malignant neoplasms. The diagnosis is usually made using histopathologic findings, but in some cases some difficulties can be found. Immunohistochemical staining is of great value in the differentiation of similar tumors. Treatment of rhabdomyoma is surgical excision. Objective To describe a case of rhabdomyoma of the larynx attended at Santa Casa de Misericórdia do Rio de Janeiro. Case Report A 35-year-old man presented with progressive hoarseness in the preceding year. Laryngoscopy showed a large submucosal tumor at the supraglottic region of the larynx. The neck computed tomography scan confirmed the submucosal mass, with distinct borders. The patient was taken to the operating suite, where endoscopic extirpation of the mass was performed. Initial histologic diagnosis was suggestive of paraganglioma, which was not confirmed by studies with immunohistochemical markers, and diagnosis was changed to adult-type rhabdomyoma. The patient recovered well. His voice returned to normal after 3 months. Discussion Although muscle tumors of the larynx are very rare, rhabdomyoma should be considered when there is a submucosal mass in the larynx.

Bartonella and Coxiella infective endocarditis in Brazil: molecular evidence from excised valves from a cardiac surgery referral center in Rio de Janeiro, Brazil, 1998 to 2009.

PCR was used to detect Coxiella burnetii and Bartonella spp in heart valves obtained during the period 1998-2009 from patients operated on for blood culture-negative endocarditis in a cardiac surgery hospital in Brazil. Of the 51 valves tested, 10 were PCR-positive; two were positive for Bartonella and one for C. burnetii.

[Clinical and epidemiological characteristics of patients with central venous catheter colonized by yeasts]. / Características clínicas e epidemiológicas de doentes com cateter venoso central colonizado por leveduras.

Among others complications due central venous catheters (CVCs), the blood infection (BI) deserves particular attention. The purposes of this study were to analyze the clinical and epidemiological characteristics of adult patients using CVC; to know the yeast colonization index; and to link it to risk factors for BI. Yeasts were investigated in 156 CVCs removed from 91 patients of the Regional University Hospital of Maringá from February to August, 2008. Yeast colonization was detected in 10.89% of the catheters, which were removed from 15 patients, three of them had a fatal hospital yeast infection due to catheter. There was a preponderance of male subjects; median age was 66 years and the mean hospitalization time was 15 days, greater than that of the non-colonized (p = 0.003). The mortality rate was significantly greater in this group than among those with non-colonized catheters (p = 0.01). Total parenteral nutrition and hemodialysis were the risk factors significantly more frequent in this group (p = 0.002 and 0.001, respectively). The most frequently found yeast was Candida parapsilosis. Among the colonized catheters those of double-lumen for infusion predominated and the site of insertion was the right subclavian vein. In conclusion the colonization by yeasts rate of CVC was 10.89% and 20% of them resulted in infection. These results add to higher mortality in patients who CVC was colonized by yeasts deserve attention considering the increasing of the hospital fungal infections.

Cardiac angiosarcoma.

Despite cardiac metastases are found in about 20% of cancer deaths, the presence of primary cardiac tumors is rare. Most primary tumors are benign, and malignant tumors comprise about 15%. We report a 21-year-old man with fever, dyspnea, and hemoptysis that was diagnosed with angiosarcoma of the right atrium and pulmonary metastasis. Patient was submitted to surgical tumor resection without adjuvant therapy and died four months after diagnosis.

Lack of effect of cell-wall targeted antibacterials on biofilm formation and antifungal susceptibility of Candida species

The use of central venous catheters (CVC) and broad-spectrum antibacterials are among the main risk factors for the development of candidemia in patients admitted to intensive care units (ICU). It is known that some antibacterials increase the resistance of these yeasts to azole antifungals. Thus, the aim of this research was to determine whether yeast present in CVC colonizations previously exposed to cell-wall targeted antibacterials benefit from a reduction in susceptibility to fluconazole and voriconazole, facilitating their ability to form biofilms. Candida albicans, C. tropicalis, C. glabrata, C. parapsilosis and C. guilhermondii were seeded into antibacterial (cefepime, meropenem, vancomycin, and piperacillin-tazobactam) gradient plates produced in Mueller-Hinton Agar. The susceptibility to fluconazole and voriconazole and the biofilm formation of the yeasts were tested before and after exposure to the antibacterials. None of the antibacterials exerted a significant effect on the in vitro susceptibility of the yeasts to the antifungal agents or on their ability to form biofilms. These results suggest that increased candidemia in ICU patients is not attributable to possible alterations in the yeasts, but is more likely caused by a weakening of the patient's general condition after long exposure to infection.

O uso de cateter venoso central (CVC) e antibióticos de amplo espectro estão entre os principais fatores de risco para o desenvolvimento da candidemia em pacientes internados em unidades de terapia intensiva (UTI). É conhecido que alguns antibióticos aumentam a resistência das leveduras aos antifúngicos azólicos. Assim, o objetivo deste estudo foi avaliar se leveduras presentes em colonização de CVC expostas a antibióticos que atuam em parede celular se beneficiam de uma redução na suscetibilidade ao fluconazol e voriconazol e se obtêm maior capacidade de formar biofilme. Candida albicans, C. tropicalis, C. glabrata,C. parapsilosis e C. guilhermondii foram semeadas em placas de Mueller-Hinton Agar, com gradientes de antibióticos (cefepima, meropenem, vancomicina e piperacilina-tazobactam). A suscetibilidade e a formação de biofilme das leveduras foram testadas antes e após a exposição aos antibióticos. Nenhum dos antibióticos provocou alterações detectáveis in vitro sobre a suscetibilidade das leveduras aos antifúngicos ou à capacidade de formar biofilme. Estes resultados sugerem que o aumento da candidemia na UTI não seria atribuído a possíveis alterações provocadas nas leveduras e sim pelo enfraquecimento da condição geral do paciente após longa exposição à infecção.

Cardiopatia reumática e endocardite infecciosa em paciente com síndrome de imunodeficiência adquirida / Rheumatic Heart Disease and Infective Endocarditis in a Patient with Acquired Immunodeficiency Syndrome

A 36-old-woman was admitted with an infectious syndrome, respiratory insufficiency and vasculitis. There was a history of chronic intravenous drug abuse, sexual promiscuity and rheumatic heart disease. She had HIV positive tests. The vasculitis and heart failure worsened and the patient died of stroke. At autopsy it was found histologic evidence of AIDS, rheumatic heart disease with Aschoff nodes, infective endocarditis with cerebral abscesses and thalamic infarction

Paciente do sexo feminino com 36 anos de idade, vida sexual promíscua e usuária de drogas endovenosas, com passado de cardite reumática, foi internada com síndrome infecciosa, insuficiência respiratória, insuficiência cardíaca congestiva e vasculite. A pesquisa para anticorpo anti-HIV foi positiva em teste realizado. Houve agravamento da vasculite e da insuficiência cardíaca e evolução para o óbito com acidente vascular cerebral. À necropsia constatou-se quadro anatomopatológico de síndrome de imunodeficiência adquirida (SIDA), cardiopatia reumática com nódulos de Aschoff e, ainda, endocardite infecciosa com abcessos cerebrais e infarto hemorrágico no tálamo.

Correlação clinicopatológica de 50 casos de síndrome de imunodeficiência adquirida: estudo retrospectivo / Clinicopathologic Correlation in 50 Cases of Acquired Immunodeficiency Syndrome. Retrospective Study

PURPOSE--To analyze myocardial abnormalities in patients of acquired immunodeficiency syndrome with clinical and pathological correlation. METHODS--We selected 50 cases, retrospectively, age ranged from 3 months to 40 years, all of them had myocardial changes and the data of clinical records fulfilled our protocol. Cases of others cardiac diseases were not included. RESULTS--The pathological findings were: myocarditis in 33 (11 had severe myocarditis) and degenerative hystological lesions in 17. The etiologic agents detected were: Toxoplasma in 11, Cryptococcus in 7 and Cytomegalovirus in 3. In 12 cases we could not find any agent. In 15 cases occurred others lesions: endocarditis, pericarditis and sarcoma of Kaposi. It was noted tachycardia in 15 cases, decrease of heart sounds in 12, arterial hypotension in seven, systolic murmur in 8, galop rhythm in 7, pericardial friction rub in 3, arrhythmia in 2. Four patients had congestive heart failure. The EKG showed sinus tachycardia in 18, ST and T changes in 10, low voltage in 5, ST segment elevation in 5 and extrasystoles in 3 cases. The echocardiogram findings were: pericardial effusion in 9 cases and 9 had ventricular dysfunction. CONCLUSION--The cardiac lesions were very important even in patients without clinical signals. We need others prospective studies with viral identification trying to detect specific lesions of HIV

Objetivo - Analisar as alterações miocárdicas na síndrome da imunodeficiência adquirida e correlacionar os achados clínicopatológicos. Métodos - Foram selecionados, retrospectivamente, 50 pacientes entre 4 meses e 40 anos de idade, que apresentavam lesões miocárdicas à histologia e cujos prontuários continham os dados do protocolo. Foram in cluídos aqueles com lesões cardíacas de outra etiologia. Resultados - Os achados anatomopatológicos foram miocardite em 33 (66%) casos, sendo grave em 11 e lesões degenerativas em 17. Os agentes etiológicos foram Toxoplasma em 11, Criptococcus em 7, Citomegalovírus em 3 e inespecífica em 12. Em 15 casos havia também outras lesões como endocardite, pericardite e sarcoma de Kaposi. Quanto aos achados clínicos observamos taquicardia em 15 casos, hipofonese de bulhas em 12, hipotensão arterial em 7, sopro sistólico em 8, ritmo de galope em 7, atrito pericárdico em 3 e arritmia cardíaca em 2. Quatro pacientes tiveram sinais de insuficiência cardíaca congestiva. O ECG mostrou taquicardia sinusal em 18, distúrbio de repolarização em 10, baixa voltagem em 5, supradesnivelamento de ST em 5 e extra-sistolia em 3. Ao ecocardiograma 9 apresentaram derrame pericárdico e 9 diminuição de contratilidade ou da função ventricular. Conclusão - As lesões cardíacas foram expressivas mesmo em pacientes sem sinais clínicos para tal. São necessários mais estudos com métodos de identificação viral para tentar detectar as lesões miocárdicas pelo HIV.

Alteraçoes cardíacas em crianças com SIDA / Cardiac changes in children with AIDS

PURPOSE: To describe the cardiac findings in children with AIDS, the follow-up with treatment and the correlation between clinical and pathological features. METHODS: We studied prospectively 25 children with clinical-laboratorial diagnosis of AIDS, ages between 3 months and 11 years, even those without cardiac symptoms. We classified the signs of AIDS following that of CDC-Atlanta 1994. Eight children died and it was done necropsy in six with macro and microscopic examinations. RESULTS: Fifteen cases had already complications of AIDS and were classified as C2 and C3, 5 as B2, 3 B1 and 2 as A1. Beside the symptoms related to the disease and infections we found signs of congestive heart failure III and IV (NYHA) in 5 children, pericardial effusion in 5, (one of them had cardiac tamponade). In the electrocardiogram (EKG), 8 children had repolarization abnormalities. In 1st echocardiogram (ECHO) we found some features of dilated myocardiopathy in 8 (6 were asymptomatic) 5 of those had pericardial effusion, one child had huge amount of pericardial liquid and also increased measures of intraventricular septum and posterior wall of left ventricle by ECHO and confirmed by necropsy examination. All cases of diagnosis of myocardiopathy received treatment with captopril and 4 also received furosemide and digoxina. Even under oral treatment three of them had deterioration of heart failure but after combined anti-retroviral drugs they showed better cardiac functions. From the six necropsied cases, two had increased heart weight without myocarditis, one had toxoplasma pancarditis and other one had fibrocalcic vasculopathy. CONCLUSION: We found several assymptomatic cases already with decreased ventricular function. Some worsened of heart failure even under apropriate treatment and showed better cardiac index after combined anti-retroviral drugs.

Melhora da disfunçäo ventricular esquerda após a correçäo cirúrgica da insuficiência mitral crônica grave / Improvement in left ventricular dysfunction after surgical correction of mitral regurgitation

OBJECTIVE: To evaluate whether left ventricular end-systolic (ESD) diameters £ 51mm in patients (pt) with severe chronic mitral regurgitation (MR) are predictors of a poor prognosis after mitral valve surgery (MVS). METHODS: Eleven pt (aged 36±13 years) were studied in the preoperative period (pre), median of 36 days; in the early postoperative period (post1), median of 9 days; and in the late postoperative period (post2), mean of 38.5±37.6 months. Clinical and echocardiographic data were gathered from each pt with MR and systolic diameter 51mm (mean = 57±4mm) to evaluate the result of MVS. Ten patients were in NYHA Class III/IV. RESULTS: All but 2 pt improved in functional class. Two pt died from heart failure and infectious endocarditis 14 and 11 months, respectively, after valve replacement. According to ejection fraction (EF) in post2, we identified 2 groups: group 1 (n=6), whose EF decreased in post1, but increased in post2 (p=0.01) and group 2 (n=5), whose EF decreased progressively from post1 to post2 (p=0.10). All pt with symptoms lasting £ 48 months had improvement in EF in post2 (p=0.01). CONCLUSION: ESD 51mm are not always associated with a poor prognosis after MVS in patients with MR. Symptoms lasting up to 48 months are associated with improvement in left ventricular function
