RESUMO

Background: A knee injury in an athlete leads to periods of forced exercise interruption. Myocardial work (MW) assessed by echocardiographic and cardiopulmonary exercise testing (CPET) are two essential methods for evaluating athletes during the period following injury. However, compared to pre-surgery evaluations, the variations in cardiovascular parameters and functional capacity assessed by these methods after surgery remain unclear. Methods: We evaluated 22 non-professional athletes aged 18-52, involved in prevalently aerobic or alternate aerobic/anaerobic sports activities, who were affected by a knee pathology requiring surgical treatment. The evaluation was performed at rest using transthoracic echocardiography, including MW assessment, and during exercise using CPET. Each athlete underwent the following two evaluations: the first before surgery and the second after surgery (specifically at the end of the deconditioning period). Results: Resting heart rate (HR) increased significantly (from 63.3 ± 10.85 to 71.2 ± 12.52 beats per minute, p = 0.041), while resting diastolic and systolic blood pressure, forced vital capacity, and forced expiratory volume in the first second did not show significant changes. Regarding the echocardiographic data, global longitudinal strain decreased from -18.9 ± 1.8 to -19.3 ± 1.75; however, this reduction was not statistically significant (p = 0.161). However, the global work efficiency (GWE) increased significantly (from 93.0% ± 2.9 to 94.8% ± 2.6, p = 0.006) and global wasted work (GWW) reduced significantly (from 141.4 ± 74.07 to 98.0 ± 50.9, p = 0.007). Additionally, the patients were able to perform maximal CPET at both pre- and post-surgery evaluations, as demonstrated by the peak respiratory exchange ratio and HR. However, the improved myocardial contractility (increased GWE and decreased GWW) observed at rest did not translate into significant changes in exercise parameters, such as peak oxygen consumption and the mean ventilation/carbon dioxide slope. Conclusions: After surgery, the athletes were more deconditioned (as indicated by a higher resting HR) but exhibited better resting myocardial contractility (increased GWE and reduced GWW). Interestingly, no significant changes in exercise capacity parameters, as evaluated by CPET, were found after surgery, suggesting that the improved myocardial contractility was offset by a greater degree of muscular deconditioning.

RESUMO

BACKGROUND: Previous studies demonstrated that variations of fT3, even within the euthyroid range, can influence cardiac function. Our aim was to investigate whether thyroid hormones, even within the euthyroid range, are associated with the magnitude of exercise-induced cardiac remodeling in Olympic athletes. METHODS: We evaluated 1342 Olympic athletes (mean age 25.6 ± 5.1) practicing different sporting disciplines (power, skills, endurance, and mixed). Athletes underwent blood testing (thyroid stimulating hormone, fT3, and fT4), echocardiography, and exercise-stress testing. Athletes taking thyroid hormones, affected by thyroiditis, or presenting TSH out of ranges were excluded. RESULTS: The level of thyroid hormones varied according to the type of sporting discipline practiced: endurance athletes presented the lowest TSH (p < 0.0001), fT3 (p = 0.007), and fT4 (p < 0.0001) in comparison to the remaining ones. Resting heart rate (HR) was positively correlated to fT3 in athletes of different disciplines (power: p = 0.0002, R2 = 0.04; skill: p = 0.0009, R2 = 0.05; endurance: p = 0.007, R2 = 0.03; and mixed: p = 0.04, R2 = 0.01). The same results were seen for peak HR in the exercise-stress test in athletes engaged in power, skill, and endurance (respectively, p < 0.0001, R2 = 0.04; p = 0.01, R2 = 0.04; and p = 0.005, R2 = 0.02). Moreover, a positive correlation was observed with cardiac dimensions, i.e., interventricular septum (power: p < 0.0001, R2 = 0.11; skill: p = 0.02, R2 = 0.03; endurance: p = 0.002, R2 = 0.03; mixed: p < 0.0001, R2 = 0.04). Furthermore, fT3 was directly correlated with the left ventricle (LV) end-diastolic volume in skills (p = 0.04, R2 = 0.03), endurance (p = 0.04, R2 = 0.01), and mixed (p = 0.04, R2 = 0.01). CONCLUSIONS: Thyroid hormones, even within the euthyroid range, are associated with cardiac adaptive response to exercise and may contribute to exercise-induced cardiac remodeling.

RESUMO

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality, and its incidence has grown within several years, quickly becoming the third leading cause of mortality. The disease is characterized by alveolar destruction, air-trapping, and chronic inflammation due to persistent exposure to a large spectrum of harmful particles. The diagnosis of COPD is made by demonstration of persistent and not fully reversible airflow limitation, and different phenotypes may be recognized based on pathophysiological, clinical, and radiological features. However, COPD is a systemic disease with effects involving several organs. For example, mechanical and functional alterations secondary to COPD involve heart function. Indeed, cardiovascular diseases are highly prevalent in patients affected by COPD and represent the primary cause of mortality in such patients. An electrocardiogram is a simple and cheap test that gives much information about the heart status of COPD patients. Consequently, variations from "normality" can be appreciated in these patients, with the most frequent abnormalities being P-wave, QRS axis, and ventricular repolarization abnormalities, in addition to conduction alterations and a vast number of arrhythmias. As a result, ECG should be routinely performed as a valuable tool to recognize alterations due to COPD (i.e., mechanical and functional) and possible associated heart diseases. This review aims to describe the typical ECG features in most COPD patients and to provide a systematic summary that can be used in clinical practice.

RESUMO

Chronic obstructive pulmonary disease (COPD) is a significant preventable and treatable clinical disorder defined by a persistent, typically progressive airflow obstruction. This disease has a significant negative impact on mortality and morbidity worldwide. However, the complex interaction between the heart and lungs is usually underestimated, necessitating more attention to improve clinical outcomes and prognosis. Indeed, COPD significantly impacts ventricular function, right and left chamber architecture, tricuspid valve functionality, and pulmonary blood vessels. Accordingly, more emphasis should be paid to their diagnosis since cardiac alterations may occur very early before COPD progresses and generate pulmonary hypertension (PH). Echocardiography enables a quick, noninvasive, portable, and accurate assessment of such changes. Indeed, recent advancements in imaging technology have improved the characterization of the heart chambers and made it possible to investigate the association between a few cardiac function indexes and clinical and functional aspects of COPD. This review aims to describe the intricate relation between COPD and heart changes and provide basic and advanced echocardiographic methods to detect early right ventricular and left ventricular morphologic alterations and early systolic and diastolic dysfunction. In addition, it is crucial to comprehend the clinical and prognostic significance of functional tricuspid regurgitation in COPD and PH and the currently available transcatheter therapeutic approaches for its treatment. Moreover, it is also essential to assess noninvasively PH and pulmonary resistance in patients with COPD by applying new echocardiographic parameters. In conclusion, echocardiography should be used more frequently in assessing patients with COPD because it may aid in discovering previously unrecognized heart abnormalities and selecting the most appropriate treatment to improve the patient's symptoms, quality of life, and survival.

RESUMO

Resumo Empatia pressupõe a capacidade e sobretudo a vontade de compreender o outro e se colocar em seu lugar. Considerando isso, espera-se que profissionais envolvidos em cuidados de saúde sejam mais empáticos e capazes de ler o mundo ao seu redor com olhar humanizado, crítico e reflexivo. Objetivou-se investigar, mediante revisão integrativa, o que tem sido discutido a respeito do ensino da empatia nos cursos de graduação da área da saúde nos últimos cinco anos. Foram selecionados 27 artigos das bases de dados MEDLINE e LILACS, por meio dos quais se identificou que a maioria dos estudos disponíveis foram realizados nas áreas de medicina e enfermagem. Além disso, constatou-se que, apesar de o tema empatia remeter à subjetividade, a metodologia quantitativa com aplicação de escalas padronizadas foi a mais utilizada para mensurar níveis de empatia e que, por fim, o ensino da empatia ocorreu por meio de metodologias ativas.


Abstract Empathy presupposes the ability and, most importantly, the willingness to understand others and put oneself in their place. Hence, health personnel are expected to be more empathetic and able to read the world around them with a humanized, critical, and reflexive look. This integrative review examines the studies on teaching empathy in undergraduate health programs published in the last five years. A total of 27 studies were selected from the MEDLINE and LILACS databases, most of which were published in the fields of medicine and nursing. Although a subjective element, most studies measured empathy using standardized scales (quantitative approach). Finally, empathy was taught using active methodologies.


Resumen La empatía es una capacidad, sobre todo una voluntad, de comprender al otro y de ponerse en su piel. Así se espera que los profesionales involucrados en el cuidado de la salud sean más empáticos y tengan una mirada humanizada, crítica y reflexiva sobre el mundo. Esta es una revisión integradora para identificar cómo se enseña la empatía en las carreras de graduación en el área de la salud en los últimos cinco años. Se seleccionaron 27 artículos de las bases de datos MEDLINE y LILACS, y se identificó que la mayoría de los estudios disponibles fueron de las áreas de Medicina y Enfermería. Se constató también que, aunque el tema de la empatía se refiera a la subjetividad, el método cuantitativo con la aplicación de escalas estandarizadas fue el más utilizado para medir los niveles de empatía y que la enseñanza de la empatía ocurrió por metodologías activas.

RESUMO

OBJECTIVES: The diagnosis of primary Sjogren's syndrome (pSS) continues to be difficult and several patients keep symptomatic for years with different diagnoses before confirmation of pSS. Since the IL-23-IL-17 axis is involved in the etiopathogenesis of pSS we evaluated by immunohistochemistry and morphometric methods the presence of IL-17 as well as IL-23 within minor salivary glands (MSG) obtained from patients with uncertain diagnosis of pSS. MATERIALS AND METHODS: 42 patients, with symptoms attributable to pSS, and 8 patients used as a control, were enrolled for the study. Autoantibody detection, histological analysis for the presence of Germinal Centers (GC+), immunohistochemistry to detect IL-23 and IL-17 were performed. RESULTS: The detection of GC + anti-SSA and anti-SSB antibody in parallel with the detection of IL-17 and IL-23, displays only a diagnostic reinforcement value. Instead, the detection of a positive reaction for both IL-17 and IL-23 without GC + or autoantibody within minor salivary glands, as detected in 36 % of patients with uncertain diagnosis, may be hold as a sensitive and specific marker to identify those patients who are likely to evolve into pSS. CONCLUSION: we suggest to use the IL-17/ IL-23 immunohistochemical detection to improve the identification of patients with a possible diagnosis in all cases which do not fully meet the American-European criteria for pSS, in particular when the GC + are not present at histopathological analysis and anti-SSA and anti-SSB antibody are undetectable in the serum.
