RESUMO
BACKGROUND: An athlete's career inevitably goes through periods of forced physical exercise interruption like a knee injury. Advanced echocardiographic methods and cardiopulmonary exercise testing (CPET) are essential in evaluating athletes in the period elapsing after the injury. However, the feasibility of a maximal pre-surgery CPET and the capacity of resting advanced echocardiographic techniques to predict cardiorespiratory capacity still need to be clarified. METHODS: We evaluated 28 non-professional athletes aged 18-52, involved in prevalently aerobic or alternate aerobic/anaerobic sports activities, affected by a knee pathology with indications for surgical treatment. The evaluation was performed at rest by trans-thoracic echocardiography, including global longitudinal strain (GLS) and myocardial work (MW) assessment, and during exercise by CPET. RESULTS: The percent-predicted peak oxygen consumption (peak VO

We describe the case of a 45-year-old female affected by asthma and nasal polyposis who presented to the emergency department because of worsening dyspnea and paresthesia of the left lower limb. Comprehensive instrumental examinations revealed the presence of severe left ventricle dysfunction, intra-cardiac thrombus, deep vein thrombosis, pulmonary embolism, lung infiltrates, polyserositis, and neurological involvements. Finally, the patient was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA), formerly Churg-Strauss syndrome, a rare vasculitis of small-medium blood vessels with several organ involvements. Treatment with anticoagulants, corticosteroids, and cyclophosphamide led to a significant clinical improvement. However, a subcutaneous cardiac defibrillator was implanted because of the persistence of severe left ventricular dysfunction and the high cardiovascular risk phenotype. Indeed, several cardiac manifestations may occur in EGPA, particularly in patients with anti-neutrophil cytoplasmic antibody-negative disease. Therefore, clinicians should have high clinical suspicion because cardiac involvement in EGPA results in a poor prognosis if not diagnosed and adequately treated.
RESUMO
Dyslipidemia is the most frequent cardiovascular (CV) risk factor in able-bodied athletes and is frequently undertreated, resulting in an underestimated risk of atherosclerosis-related diseases. Data on lipid profile in Paralympic athletes are lacking. Our study aimed to identify the prevalence of dyslipidemia and the influence of disability type and sporting discipline in Paralympic athletes. We evaluated 289 athletes who participated in the Paralympic Games from London 2012 to Beijing 2022. All athletes underwent clinical/physical evaluation, blood tests, and body composition analysis. They were divided into different groups based on sports disciplines and disability type (spinal cord injuries [SCIs] and non-SCIs [NSCIs]). Among the Paralympic athletes, 34.6% had a low-density lipoprotein (LDL) level ≥115 mg/100 ml. They were older (38.1 ± 9.2 vs 30.6 ± 9.6, p = 0.001) and had a higher CV risk. Athletes with SCI showed similar total cholesterol and triglycerides, higher LDL (110.9 ± 35.2 vs 102.7 ± 30.6 mg/100 ml, p = 0.03) and lower high-density lipoprotein (HDL) (53.6 ± 13.6 vs 60.5 ± 15.4 mg/100 ml, p = 0.001) than those with NSCI. Endurance athletes had lower LDL, the highest HDL, and the lowest triglycerides and LDL/HDL ratio compared with other sports disciplines. A mean follow-up of 61.5 ± 30.5 months was available in 47% athletes, and 72.7% of the athletes with dyslipidemia continued to present altered LDL values at follow-up. In conclusion, dyslipidemia is the most common CV risk factor in the Paralympics, affecting 35% of athletes, with only mild lipid changes over a medium-term time. The type of disability and sporting discipline has an impact on lipids, improving HDL and reducing LDL, with a better profile observed in NSCI and endurance athletes.

Myocarditis is a polymorphic and potentially life-threatening disease characterized by a large variability in clinical presentation and prognosis. Within the broad spectrum of etiology, eosinophilic myocarditis represents a rare condition characterized by eosinophilic infiltration of the myocardium, usually associated with peripheral eosinophilia. Albeit uncommon, eosinophilic myocarditis could be potentially life-threatening, ranging from mild asymptomatic disease to multifocal widespread infiltrates associated with myocardial necrosis, thrombotic complications, and endomyocardial fibrosis. Moreover, it could progress to dilated cardiomyopathy, resulting in a poor prognosis. The leading causes of eosinophilic myocarditis are hypersensitivity reactions, eosinophilic granulomatosis with polyangiitis, cancer, hyper-eosinophilic syndrome variants, and infections. A thorough evaluation and accurate diagnosis are crucial to identifying the underlying cause and defining the appropriate therapeutic strategy. On these bases, this comprehensive review aims to summarize the current knowledge on eosinophilic myocarditis, providing a schematic and practical approach to diagnosing, evaluating, and treating eosinophilic myocarditis.
RESUMO
Regenerative or stem cell therapy is an emerging field of treatment based on stimulation of endogenous resident stem cells or administration of exogenous stem cells to treat diseases or injury and to replace malfunctioning or damaged tissues. Current evidence suggests that in the lung, these cells may participate in tissue homeostasis and regeneration after injury. Animal and human studies have demonstrated that tissue-specific stem cells and bone marrow-derived cells contribute to lung tissue regeneration and protection, and thus administration of exogenous stem/progenitor cells or humoral factors responsible for the activation of endogenous stem/progenitor cells may be a potent next-generation therapy for chronic obstructive pulmonary disease. The use of bone marrow-derived stem cells could allow repairing and regenerate the damaged tissue present in chronic obstructive pulmonary disease by means of their engraftment into the lung. Another approach could be the stimulation of resident stem cells by means of humoral factors or photobiostimulation.

Type 2 diabetes mellitus is a common comorbidity of COPD, but there are still many doubts about the relation among diabetes and COPD. We retrospectively collected data from patients afferent to our Respiratory Diseases outpatient clinic at the Tor Vergata University Hospital between 2010 and 2012. The study population was analyzed by clusters of age, gender, body mass index (BMI), smoking status, lung function, concomitant pharmacologic therapies and comorbidities. The values of the association between variables were expressed as odds ratio. Data were adjusted for gender, age and possible confounding variables by Mantel-Haenszel method. We identified 493 patients with COPD. Ninety-two (18.7 %) patients were affected by type 2 diabetes mellitus, with no significant gender differences. The prevalence distribution was similar among the different age clusters, but the association was stronger in patients younger than 65 years. The association was present only in obese subjects in whom it was significant only in patients with moderate-to-severe COPD, but not mild COPD. The presence of cardiovascular diseases was significantly associated with diabetes mellitus in patients with COPD. There was a slight association of inhaled corticosteroid (ICS) use with the presence of diabetes mellitus in COPD, but the combination of an ICS with a ß2-agonist apparently reduced this association. The association with type 2 diabetes mellitus was greater in patients with COPD respect to general population, and correlated with the increase in BMI and the presence of other comorbidities, suggesting that both diseases may be targets of systemic inflammation.
