Brazilian Thoracic Association recommendations for the management of post-tuberculosis lung disease.

Historically, all efforts against tuberculosis were focused on rapid diagnosis and effective treatment to break the chain of transmission of Mycobacterium tuberculosis. However, in the last few years, more and more evidence has been found on the dramatic consequences of the condition defined as post-tuberculosis lung disease (PTLD). Approximately one third of patients surviving pulmonary tuberculosis face considerable ongoing morbidities, including respiratory impairment, psychosocial challenges, and reduced health-related quality of life after treatment completion. Given the important global and local burden of tuberculosis, as well as the estimated burden of PTLD, the development of a consensus document by a Brazilian scientific society-Sociedade Brasileira de Pneumologia e Tisiologia (SBPT)-was considered urgent for the prevention and management of this condition in order to allocate resources to and within tuberculosis services appropriately and serve as a guide for health care professionals. A team of eleven pulmonologists and one methodologist was created by the SBPT to review the current evidence on PTLD and develop recommendations adapted to the Brazilian context. The expert panel selected the topics on the basis of current evidence and international guidelines. During the first phase, three panel members drafted the recommendations, which were divided into three sections: definition and prevalence of PTLD, assessment of PTLD, and management of PTLD. In the second phase, all panel members reviewed, discussed, and revised the recommendations until a consensus was reached. The document was formally approved by the SBPT in a special session organized during the 2023 SBPT Annual Conference.

Programa Saúde na Escola: avanços, dificuldades e desafios na promoção da saúde nas escolas do Brasil / Health at School Program: advances, difficulties and challenges in health promotion in schools in Brazil

O Brasil passou por um extenso percurso histórico até a institucionalização de um programa nacional para atuação no âmbito escolar. A realização deste estudo justifica-se diante da necessidade de se analisar como a promoção da saúde vem se efetivando dentro das escolas do país, possibilitando uma reflexão sobre a efetividade das atividades até então realizadas, assim como embasar a execução das próximas ações pela gestão e por profissionais de saúde no âmbito deste programa. Teve como objetivo identificar avanços, dificuldades e desafios para promoção da saúde nas escolas brasileiras pós implementação do Programa Saúde na Escola (PSE). Trata-se de uma revisão integrativa da literatura, realizada nas bases de dados Scientific Electronic Library Online (Scielo), Google Scholar e Biblioteca Virtual em Saúde (BVS), para responder à questão-norteadora: o que estudos trazem acerca dos avanços, dificuldades e desafios para promoção da saúde nas escolas brasileiras pós implementação do PSE? As buscas ocorreram em outubro de 2021, com os descritores "promoção da saúde", "serviço de saúde escolar", e "Brasil". Identificaram-se 511 artigos, dos quais 17 foram selecionados pelos critérios de elegibilidade, avaliados quanto ao rigor metodológico e nível de evidência. Os 17 artigos apresentaram nível de evidência VI. Identificaram-se avanços no percurso da promoção da saúde, como aproximação do vínculo escola-família e unidade de saúde e a atuação multiprofissional nas atividades pactuadas. Contudo, apontou-se como dificuldades e desafios sobrecarga e acúmulo de atividades pelos profissionais, carência de insumos materiais, infraestrutura inadequada, fragilidades de vínculos intersetoriais e ações fragmentadas e centradas na prevenção de doenças.

Brazil has gone through an extensive historical journey until the institutionalization of a national program to work in the school environment. The realization of this study is justified by the need to analyze how health promotion has been carried out within the country's schools, allowing a reflection on the effectiveness of the activities carried out until then, as well as supporting the execution of the next actions by the management and by health professionals under this program. It aimed to identify advances, difficulties and challenges for health promotion in Brazilian schools after the implementation of the School Health Program (PSE). This is an integrative literature review, carried out in the Scientific Electronic Library Online (Scielo), Google Scholar and Virtual Health Library (BVS) databases, to answer the guiding question: what studies bring about the advances, difficulties, and challenges for health promotion in Brazilian schools after PSE implementation? The searches took place in October 2021, with the descriptors "health promotion", "school health service", and "Brazil". A total of 511 articles were identified, of which 16 were selected according to eligibility criteria, evaluated for methodological rigor and level of evidence. The 16 articles presented level of evidence VI. Advances were identified in the path of health promotion, such as the approximation of the school-family bond and the health unit and the multiprofessional action in the agreed activities. However, it was pointed out as difficulties and challenges overload and accumulation of activities by professionals, lack of material inputs, inadequate infrastructure, weaknesses of intersectoral bonds and fragmented actions focused on disease prevention.

Brazilian Thoracic Association recommendations for the management of post-tuberculosis lung disease / Recomendações da Sociedade Brasileira de Pneumologia e Tisiologia para o manejo da doença pulmonar pós-tuberculose

RESUMO Historicamente, todos os esforços contra a tuberculose concentraram-se no diagnóstico rápido e no tratamento efetivo para quebrar a cadeia de transmissão do Mycobacterium tuberculosis. No entanto, nos últimos anos, têm sido encontradas mais e mais evidências sobre as dramáticas consequências da condição definida como doença pulmonar pós-tuberculose (DPPT). Aproximadamente um terço dos pacientes que sobrevivem à tuberculose pulmonar enfrenta morbidades consideráveis e persistentes, incluindo comprometimento respiratório, desafios psicossociais e redução da qualidade de vida relacionada à saúde após o término do tratamento. Diante da importante carga global e local da tuberculose, bem como da carga estimada da DPPT, considerou-se urgente o desenvolvimento de um documento de consenso por uma sociedade científica brasileira - a Sociedade Brasileira de Pneumologia e Tisiologia (SBPT) - para a prevenção e manejo dessa condição, a fim de alocar recursos de forma adequada para e nos serviços de tuberculose e servir de guia para os profissionais de saúde. Uma equipe de onze pneumologistas e um metodologista foi criada pela SBPT para revisar as evidências atuais sobre a DPPT e desenvolver recomendações adaptadas ao contexto brasileiro. O painel de especialistas selecionou os temas com base nas evidências atuais e diretrizes internacionais. Durante a primeira fase, três membros do painel redigiram as recomendações, que foram divididas em três seções: definição e prevalência de DPPT, avaliação da DPPT e manejo da DPPT. Na segunda fase, todos os membros do painel analisaram, discutiram e revisaram as recomendações até chegar a um consenso. O documento foi aprovado formalmente pela SBPT em sessão especial organizada durante o Congresso Anual da SBPT de 2023.

Early Change in Area Strain Detected by 3D Speckle Tracking Is Associated With Subsequent Cardiotoxicity in Patients Treated With Low Doses of Anthracyclines.

Objective: To evaluate the prognostic impact of the parameters of myocardial deformation using three-dimensional speckle tracking echocardiography (3DSTE) in patients with breast cancer who underwent chemotherapy with low doses of anthracyclines. Background: Chemotherapy-related cardiotoxicity has an important prognostic impact on cancer survivors. Three-dimensional STE has revealed more consistent data than two-dimensional techniques and may represent a more accurate tool in the evaluation of myocardial function in patients who underwent chemotherapy. Methods: We evaluated patients with breast cancer who were treated with anthracyclines (associated or not with trastuzumab) in five stages: baseline, after cumulative doses of 120 and 240 mg/m2 of doxorubicin, and then, after 6 months and at least 1 year after anthracyclines. Ultrasensitive troponin I (US-TnI) and a standard echocardiography study were performed at each stage. We analyzed left ventricular ejection fraction (LVEF) by Simpson's method, two-dimensional speckle tracking (2DSTE) with longitudinal and radial strain values, and 3DSTE with longitudinal, radial, and circumferential strain as well as twist, torsion, rotation, and three-dimensional global area strain (3DGAS). Cardiotoxicity was defined as a decrease in LVEF by more than 10 percentage points to a value lower than 53%. Results: We evaluated 51 female patients who were aged 50.6 ± 11 years. After the cumulative dose of 240 mg/m2 of doxorubicin, US-TnI was increased (>34 pg/ml) in 21 patients (45%, p > 0.001), LVEF remained unchanged (p = 0.178), while 2DSTE longitudinal strain was decreased (from -17.8% to -17.1%, p < 0.001) and 3DSTE detected changes in longitudinal, radial, circumferential, and area strain. After a lower cumulative dose of doxorubicin (120 mg/m2), 3DGAS (p < 0.001) was the only parameter that was changed. In the follow-up, 7 (13%) patients presented a decrease in LVEF. Three-dimensional GAS early changed to abnormal values was the only variable associated with a subsequent decrease in LVEF (definitive cardiotoxicity). Conclusion: In patients with breast cancer, 3DSTE detected early changes in area strain after very low doses of doxorubicin. The 3DGAS early changed to abnormal values was associated with a subsequent decrease in LVEF, representing a promising technique to predict chemotherapy-induced cardiomyopathy.

Worldwide Effects of Coronavirus Disease Pandemic on Tuberculosis Services, January-April 2020.

Coronavirus disease has disrupted tuberculosis services globally. Data from 33 centers in 16 countries on 5 continents showed that attendance at tuberculosis centers was lower during the first 4 months of the pandemic in 2020 than for the same period in 2019. Resources are needed to ensure tuberculosis care continuity during the pandemic.

Contentamento de puérperas assistidas por enfermeiros obstetras / Contentment of puerperal women assisted by obstetric nurses

Objetivo: avaliar os cuidados e a satisfação de puérperas assistidas por enfermeiros obstetras em um Centro de Parto Normal. Método: estudo quantitativo, descritivo e exploratório, realizado em uma maternidade pública de referência com 25 puérperas. Os dados foram coletados mediante a adaptação do Questionário de Experiência e Satisfação com o Parto (QEPS) e analisados a partir de estatística descritiva. Resultados: 100% das parturientes destacaram os cuidados para resguardar sua intimidade, o ensinamento de botar força para facilitar a expulsão do bebê e a importância do acompanhante no transcorrer do parto como muito importantes; 91% relataram que sempre receberam informação a respeito do processo parturitivo; 95,7% enfatizaram a importância de estratégias não farmacológicas para acelerar o parto e diminuir a dor e 95,7% mostraram-se satisfeitas com os cuidados prestados pelo enfermeiro obstetra e a equipe de Enfermagem durante o trabalho de parto. Conclusão: a assistência do enfermeiro obstetra foi bastante aceita pelas parturientes, porém, ainda precisa de apoio e acreditação por parte dos demais profissionais da saúde obstétrica.(AU)

Risk factors for tuberculosis: diabetes, smoking, alcohol use, and the use of other drugs.

Tuberculosis continues to be a major public health problem. Although efforts to control the epidemic have reduced mortality and incidence, there are several predisposing factors that should be modified in order to reduce the burden of the disease. This review article will address some of the risk factors associated with tuberculosis infection and active tuberculosis, including diabetes, smoking, alcohol use, and the use of other drugs, all of which can also contribute to poor tuberculosis treatment results. Tuberculosis can also lead to complications in the course and management of other diseases, such as diabetes. It is therefore important to identify these comorbidities in tuberculosis patients in order to ensure adequate management of both conditions.

RESUMO A tuberculose continua a ser um importante problema de saúde para a humanidade. Embora os esforços para controlar a epidemia tenham reduzido sua mortalidade e incidência, há vários fatores predisponentes a ser controlados a fim de reduzir a carga da doença. Este artigo de revisão aborda alguns dos fatores de risco associados à infecção por tuberculose, como diabetes, tabagismo, uso de álcool e uso de outras drogas, que podem também contribuir para maus resultados do tratamento da tuberculose. A tuberculose pode levar a complicações no curso e no manejo de outras doenças, como o diabetes. Portanto, é importante identificar essas comorbidades em pacientes com tuberculose a fim de assegurar um manejo adequado de ambas as condições.

Anticoagulação no paciente oncologico / Anticoagulation in the oncologic patient

A doença neoplásica associa-se a um aumento da incidência de eventos tromboembólicos. Os fatores associados a esses fenômenos englobam não apenas o estado pró-trombótico associado ao câncer, mas também os efeitos colaterais dos quimioterápicos, além da imobilidade associada a algumas situações, como intervenções cirúrgicas, por exemplo. De acordo com a American Cancer Society (ACS), que desenvolveu a mais recente diretriz sobre profilaxia e tratamento da TVP em pacientes oncológicos, somando os fatores de risco já existentes aos fatores intrínsecos dos pacientes oncológicos, esses pacientes são, quase sempre, classificados como de alto risco. A simplicidade de administração oral sem necessidade de monitorização laboratorial torna os novos anticoagulantes orais uma alternativa atrativa para a prevenção e o manejo de eventos tromboembólicos em pacientes oncológicos. Subgrupos de estudos maiores demonstram a eficácia e segurança dessa classe de fármacos nesse grupo de pacientes, porém, mais estudos estão sendo conduzidos, a fim de responder com mais clareza a esta questão. O estado pró-trombótico promovido pela doença neoplásica acarreta maior risco de fenômenos embólicos em pacientes oncológicos com fibrilação atrial (FA). Não existem recomendações específicas para terapia antitrombótica para pacientes com FA e câncer. Não há evidência que essa população apresente risco aumentado de acidente vascular cerebral embólico em comparação com os pacientes com FA sem neoplasia associada. Os pacientes portadores de FA e câncer concomitantemente são mais idosos do que os pacientes portadores apenas de FA. Ainda existem muitas controvérsias com relação à anticoagulação no paciente oncológico. Novos estudos com foco nessa temá- tica contribuirão muito para o manejo mais homogêneo e embasado nessa população

Neoplastic disease is associated with an increase in the incidence of thromboembolic events. Factors associated with these phenomena include not only the prothrombotic state associated with cancer, but also the side effects of chemotherapy, and the immobility associated with certain situations, such as surgical interventions. According to the American Cancer Society (ACS), which produced the latest guidelines on prophylaxis and treatment of DVT in cancer patients, adding the existing risk factors to the intrinsic factors of cancer patients, these patients are almost always classified as high risk. The simplicity of oral administration, without the need for laboratory monitoring, makes the new oral anticoagulants an attractive alternative in the prevention and management of thromboembolic events in cancer patients. Subgroups of larger studies demonstrate the efficacy and safety of this class of drugs in this group of patients. However, further studies are being conducted in order to answer this question more clearly. The prothrombotic state promoted by the neoplastic disease presents a higher risk of embolic phenomena in cancer patients with atrial fibrillation (AF). There are no specific recommendations for antithrombotic therapy in patients with AF and cancer. There is no evidence that this population presents an increased risk of embolic cerebrovascular event compared to patients with AF without associated neoplasia. It is known that cancer patients with concomitant cancer and AF are older than non-cancer patients. There is still much controversy regarding anticoagulation in cancer patients. New studies focusing on this theme will contribute to a more homogeneous and grounded management of this population

Analysis Treatment Guideline versus Clinical Practice Protocol in Patients Hospitalized due to Heart Failure / Análise de Diretriz de Tratamento versus Protocolo Assistencial em Pacientes Internados por Insuficiência Cardíaca

Background: Despite the availability of guidelines for treatment of heart failure (HF), only a few studies have assessed how hospitals adhere to the recommended therapies. Objectives: Compare the rates of adherence to the prescription of angiotensin-converting enzyme inhibitor or angiotensin II receptor blockers (ACEI/ARB) at hospital discharge, which is considered a quality indicator by the Joint Commission International, and to the prescription of beta-blockers at hospital discharge, which is recommended by national and international guidelines, in a hospital with a case management program to supervise the implementation of a clinical practice protocol (HCP) and another hospital that follows treatment guidelines (HCG). Methods: Prospective observational study that evaluated patients consecutively admitted to both hospitals due to decompensated HF between August 1st, 2006, and December 31st, 2008. We used as comparing parameters the prescription rates of beta-blockers and ACEI/ARB at hospital discharge and in-hospital mortality. Results: We analyzed 1,052 patients (30% female, mean age 70.6 ± 14.1 years), 381 (36%) of whom were seen at HCG and 781 (64%) at HCP. The prescription rates of beta-blockers at discharge at HCG and HCP were both 69% (p = 0.458), whereas those of ACEI/ARB were 83% and 86%, respectively (p = 0.162). In-hospital mortality rates were 16.5% at HCP and 27.8% at HCG (p < 0.001). Conclusion: There was no difference in prescription rates of beta-blocker and ACEI/ARB at hospital discharge between the institutions, but HCP had lower in-hospital mortality. This difference in mortality may be attributed to different clinical characteristics of the patients in both hospitals.

Fundamento: Apesar da disponibilidade de diretrizes de tratamento para insuficiência cardíaca (IC), há poucos estudos avaliando a adesão dos hospitais ao tratamento preconizado. Objetivos: Comparar as taxas de adesão à prescrição de inibidor da enzima conversora da angiotensina ou antagonista do receptor de angiotensina II (IECA/BRA) na alta hospitalar, considerada indicadora de qualidade pela Joint Commission International, e à prescrição de betabloqueador na alta hospitalar, preconizada por diretrizes nacionais e internacionais, em um hospital que utiliza gerenciamento de casos para supervisionar a implementação de um protocolo assistencial (HPA) e outro que utiliza diretrizes de tratamento (HDT). Métodos: Estudo observacional prospectivo que avaliou pacientes consecutivamente admitidos em ambos os hospitais por IC descompensada entre 1º de agosto de 2006 a 31 de dezembro de 2008. Os parâmetros comparados entre os hospitais foram as taxas de prescrição de betabloqueador e IECA/BRA na alta hospitalar e a mortalidade intra-hospitalar. Resultados: Analisamos 1.052 pacientes (30% do sexo feminino, média de idade 70,6 ± 14,1 anos) dos quais 381 (36%) eram do HDT e 781 (64%) do HPA. No HDT e no HPA, as taxas de prescrição de betabloqueador na alta foram ambas de 69% (p = 0,458), e de prescrição de IECA/BRA foi de 83% e 86%, respectivamente (p = 0,162). A mortalidade intra-hospitalar foi de 16,5% no HPA e de 27,8% no HDT (p < 0,001). Conclusão: Não houve diferença entre as instituições em relação à prescrição de betabloqueador e IECA/BRA na alta hospitalar, mas a mortalidade intra-hospitalar foi menor no HPA. Esta diferença na mortalidade pode ser atribuída às características clínicas distintas dos pacientes em ambos os hospitais.

Effects of environmental stress following myocardial infarction on behavioral measures and heart failure progression: The influence of isolated and group housing conditions.

BACKGROUND: Heart failure (HF) prognosis is negatively influenced by adverse environmental conditions associated with psychological distress and depression. The underlying mechanisms are not well understood because of insufficient experimental control in prior clinical and epidemiological studies. Using a validated animal model we examined whether distress-producing environmental manipulations (social isolation and crowding) increase HF progression following myocardial infarction (MI). METHODS: MI was induced using coronary artery ligation in 8-week old male Wistar rats (N=52) and results were compared to sham surgery (N=24). Housing conditions were randomly assigned at 5 days post MI or sham surgery (1/cage=isolation, 2/cage=standard reference condition, or 4/cage=crowding) and continued for 17 weeks until the end of observation. The open field test was used to test behavioral responses. Echocardiograms were obtained at weeks 8 and 16, and left ventricular (LV) weight at week 17. RESULTS: Housing conditions increased behavioral markers of distress (p=0.046) with the strongest effects for the isolated (1/cage) (p=0.022). MI did not increase distress-related behaviors compared to sham. MI-surgery resulted in characteristic HF indices (left ventricular ejection fraction (LVEF) at week 16=46 ± 12% vs. 80 ± 7% in sham, p<0.001). Housing condition was not related to LVEF or LV weight (p>0.10). CONCLUSIONS: Adverse environmental conditions, particularly isolated housing, produce increases in some of the behavioral indicators of distress. No effects of housing were found on post-MI progression of HF. The distress-HF associations observed in humans may therefore reflect common underlying factors rather than an independent causal pathway. Stronger environmental challenges may be needed in future animal research examining distress as related HF progression.

Vitamin D intoxication: case report.

Hypervitaminosis D is a rarely reported condition. In general it is only perceived when hypercalcemia is not resolved. The use of vitamin D has increased in recent years because of its benefits, but as a result, intoxication cases have occurred more frequently. This report describes a patient who presented worsening of renal function and hypercalcemia. After investigation, vitamin D intoxication was confirmed and it was due to an error in compounding.

This report describes a patient who presented worsening of renal function and hypercalcemia. After investigation, vitamin D intoxication was confirmed and it was due to an error in compounding.

A hipervitaminose D é pouco relatada. Geralmente, só é percebida quando o quadro de hipercalcemia não se resolve. Em razão de seus benefícios, o uso de vitamina D aumentou nos últimos anos; consequentemente, os casos de intoxicação também tiveram aumento. Este relato destacou um caso em que o paciente apresentava piora da função renal e hipercalcemia. Após investigação, ficou confirmada a intoxicação por vitamina D devido a um erro de manipulação da droga.

Effect of a high-protein diet on development of heart failure in response to pressure overload.

Heart failure treatment guidelines provide no recommendations regarding the intake of protein, though it has been proposed that increasing protein intake may result in clinical improvement. High-protein intake might improve protein synthesis and cell function, and prevent deterioration in mitochondrial and left ventricular function. We assessed the effects of a high-protein diet on the development of heart failure characterized by cardiac hypertrophy, impaired mitochondrial oxidative metabolism and contractile dysfunction induced by transverse aortic constriction in rats. A standard diet with 18% of energy intake from protein was compared with a high-protein diet (30% of energy intake). First, we evaluated the effects of protein intake on the development of heart failure during 14 weeks of aortic constriction, and found similar cardiac hypertrophy, contractile dysfunction, ventricular dilation, and decreased cardiac mitochondrial oxidative capacity with both 18% and 30% protein. We then assessed more advanced heart failure, with 22 weeks of aortic constriction. We again saw no difference in cardiac mass, left ventricular volume, mitochondrial oxidative capacity or resistance to permeability transition between the 18% and 30% protein diets. There was a modest but significant decrease in survival with heart failure with the 30% protein diet compared with 18% protein (p < 0.003). In conclusion, consumption of a high-protein diet did not affect cardiac mass, left ventricular volumes or ejection fraction, or myocardial mitochondrial oxidative capacity in rats with pressure overload induced heart failure, but significantly decreased survival.
