RESUMO

Background/Objectives: Although long-term COVID-19 symptoms are common, little is known about the management of post-COVID-19 condition. The aim of the current report is to evaluate the effects of a combination of lactoferrin, lysozyme, lactobacillus, resveratrol, vitamins, and oligoelements (PIRV-F20®) on the exercise capacity of post-COVID-19 patients. Methods: A retrospective analysis of consecutive patients referred to a specific outpatient clinic dedicated to post-COVID-19 condition from April 2022 to April 2023 was conducted. Subjects of both sexes, aged ≥18 years, with previous COVID-19 in the preceding 12 months, persistent symptoms consistent with post-COVID syndrome, and initial exercise impairment were included. Exclusion criteria were as follows: active cancer, end-stage conditions, severe musculoskeletal conditions, or patients with a history of limited functional capacity, pregnancy, or breastfeeding. Patients who reported having taken PIRV-F20® for at least 6 weeks were compared to patients who refused this treatment. Six-minute walking distance was the primary endpoint. Results: Forty-four patients (56.8% women, aged 49.1 ± 18.1 years) were included in the study. The group of patients who reported having taken PIRV-F20® exhibited a significant improvement of 6MWD (median: +40 m; IQR: 10-65 m, p vs. baseline: 0.02), which was significantly superior (p: 0.01) when compared to the controls (median: +10 m; IQR: -5-30 m). No differences were found with regard to muscular strength, echocardiographic parameters, and perception of symptoms. Conclusions: Post-COVID-19 individuals who reported having taken PIRV-F20® for at least six weeks showed a significant improvement in exercise capacity. This finding should be confirmed in larger, prospective, randomized controlled trials.

RESUMO

Early detection and treatment of cancer have led to a noticeable reduction in both mortality and morbidity. However, chemotherapy and radiotherapy could exert cardiovascular (CV) side effects, impacting survival and quality of life, independent of the oncologic prognosis. In this regard, a high clinical index of suspicion is required by the multidisciplinary care team in order to trigger specific laboratory tests (namely natriuretic peptides and high-sensitivity cardiac troponin) and appropriate imaging techniques (transthoracic echocardiography along with cardiac magnetic resonance, cardiac computed tomography, and nuclear testing (if clinically indicated)), leading to timely diagnosis. In the near future, we do expect a more tailored approach to patient care within the respective community along with the widespread implementation of digital health tools.

RESUMO

BACKGROUND: Hypertension management in older patients represents a challenge, particularly when hospitalized. OBJECTIVE: The objective of this study is to investigate the determinants and related outcomes of antihypertensive drug prescription in a cohort of older hospitalized patients. METHODS: A total of 5671 patients from REPOSI (a prospective multicentre observational register of older Italian in-patients from internal medicine or geriatric wards) were considered; 4377 (77.2%) were hypertensive. Minimum treatment (MT) for hypertension was defined according to the 2018 ESC guidelines [an angiotensin-converting-enzyme-inhibitor (ACE-I) or an angiotensin-receptor-blocker (ARB) with a calcium-channel-blocker (CCB) and/or a thiazide diuretic; if >80 years old, an ACE-I or ARB or CCB or thiazide diuretic]. Determinants of MT discontinuation at discharge were assessed. Study outcomes were any cause rehospitalization/all cause death, all-cause death, cardiovascular (CV) hospitalization/death, CV death, non-CV death, evaluated according to the presence of MT at discharge. RESULTS: Hypertensive patients were older than normotensives, with a more impaired functional status, higher burden of comorbidity and polypharmacy. A total of 2233 patients were on MT at admission, 1766 were on MT at discharge. Discontinuation of MT was associated with the presence of comorbidities (lower odds for diabetes, higher odds for chronic kidney disease and dementia). An adjusted multivariable logistic regression analysis showed that MT for hypertension at discharge was associated with lower risk of all-cause death, all-cause death/hospitalization, CV death, CV death/hospitalization and non-CV death. CONCLUSIONS: Guidelines-suggested MT for hypertension at discharge is associated with a lower risk of adverse clinical outcomes. Nevertheless, changes in antihypertensive treatment still occur in a significant proportion of older hospitalized patients.

RESUMO

Sacubitril/Valsartan (sac/val) has improved clinical prognosis in patients affected by heart failure (HF) with reduced ejection fraction (HFrEF). HF and type 2 diabetes mellitus (T2DM) frequently coexist, with a prevalence of T2DM of 35%-40% in patients with HF. T2DM is the third co-morbidities in patients with HF and a strong independent risk factor for the progression of HF. In a post hoc analysis of PARADIGM-HF, improved glycemic control was shown in patients with T2DM and HFrEF receiving sac/val compared to enalapril at 12 months of follow-up. The aim of the present study was to evaluate, in a series of repeated observations in 90 HFrEF patients, the long term effect of sac/val treatment on renal function, glycometabolic state and insulin sensitivity parameters, according to diabetic status. We studied 90 patients (74 men and 16 women, mean age 68 ± 10 years, 60 diabetics and 30 non-diabetics) suffering from HFrEF and still symptomatic despite optimal pharmacological therapy. Patients with left ventricular ejection fraction (LVEF) <35% and II-III NYHA functional class were enrolled. All patients underwent clinical-instrumental and laboratory determinations and Minnesota Living with HF Questionnaire (MLHFQ) every 6 months until 30 months to evaluate benefits and adverse events. After 30 months follow-up, we observed a significant improvement in glycometabolic parameters including HbA1c, fasting glucose and insulin, insulin-like growth factor-1 (IGF-1), HOMA index, and LDL cholesterol. Moreover, renal function, NTpro-BNP levels and echocardiographic parameters significantly improved. In diabetic patients a significant reduction in use of oral antidiabetic drugs and insulin was observed after 30 months of sac/val treatment. In the whole population, multivariate analysis shows that the evolution of cardiac index (CI) was significantly associated to simultaneous changes in HOMA, IGF-1 and visit; per each visit and for 1 ng/ml increase in IGF-1 there was an increase in CI of 64.77 ml/min/m2 (p < 0.0001) and 0.98 ml/min/m2 (p = 0.003), respectively, whereas 1 point increase in HOMA was associated with a -7.33 ml/min/m2 (p = 0.003) reduction in CI. The present data confirm persistent metabolic improvement in patients with HFrEF after treatment with sac/val and highlights its potential therapeutical role in patients with metabolic comorbidities.

RESUMO

Data regarding further risk stratification of intermediate-risk pulmonary embolism (IR-PE) are scanty. Whether transthoracic echocardiography may be helpful in further risk assessment of death in such population has still to be proven. Two-hundred fifty-four consecutive patients (51.6% females, age 63.7 ± 17.3 years) with IR-PE admitted to a tertiary regional referral center were enrolled. Patients underwent a complete transthoracic echocardiography within 36 h from hospital admission, on top of clinical assessment, physical examination, computer tomography pulmonary angiography (CTPA), and serum measurement of Troponin I (TnI) levels. The occurrence of 90 day mortality was chosen as primary outcome measure. When compared to survivors, non-surviving IR-PE patients had smaller left-ventricular end-diastolic volumes (39.8 ± 20.9 vs 49.4 ± 19.9 ml/m2, p = 0.006) with reduced stroke volume index (SVi) (24.7 ± 10.9 vs 30.9 ± 12.6 ml/m2, p: 0.004) and time-velocity integral at left-ventricular outflow tract (VTILVOT) (0.17 ± 0.03 vs 0.20 ± 0.04 m, p = 0.0001), whereas no differences were recorded regarding right heart parameters. Cox regression analysis revealed that right atrial enlargement (RAE) (HR 3.432, 5-95% CI 1.193-9.876, p: 0.022), the ratio between tricuspid annulus plane excursion and pulmonary arterial systolic pressure (TAPSE/PASp) (HR 4.833, 5-95% 1.230-18.986, p = 0.024), as well as SVi (HR 11.199, 5-95% CI 2.697-48.096, p = 0.001) and VTILVOT (HR 4.212, 5-95% CI 1.384-12.820, p = 0.011) were powerful independent predictors of mortality. Neither CTPA RV/LV nor TnI resulted associated with impaired survival. In intermediate-risk pulmonary embolism, RAE, TAPSE/PASp ratio, SVi, and VTILVOT predict independently prognosis to a greater extent than CTPA and TnI.

RESUMO

Angiodysplasia, defined as a vascular ectasia or arteriovenous malformation, is the most frequent cause of occult bleeding in patients older than 60 years and a significant association with several cardiac condition is described. Patients with anemia and negative findings on upper endoscopy and colonoscopy should be referred for further investigation of the small bowel. The investigation of choice, when available, is wireless capsule endoscopy. Several therapeutic options are available in this cases, as we reviewed in this report. We report a case of 78-year old man admitted to our Intensive Coronary Unit for dyspnea and chest pain. A diagnosis of non-ST-segment elevation acute coronary syndrome was made and a concomintant, significant anemia was found (hemoglobin 8.2 g/dl). No cororary disease was found by an angiography though the past medical history revealed systemic hypertension, chronic kidney disease (KDOQY stage III), and diabetes mellitus type II on insuline therapy. A Wireless Video capsule examination was positive for jejunum angiodysplasia and an argon plasma coagulation was chosen as terapeutic option. No subsequent supportive therapy and interventions were required in subsequent one year of follow-up.

RESUMO

In recent years, the remarkable progress achieved in terms of survival after myocardial infarction have led to an increased incidence of chronic heart failure in survivors. This phenomenon is due to the still incomplete knowledge we possess about the complex pathophysiological mechanisms that regulate the response of cardiac tissue to ischemic injury. These involve various cell types such as fibroblasts, cells of the immune system, endothelial cells, cardiomyocytes and stem cells, as well as a myriad of mediators belonging to the system of cytokines and not only. In parallel with the latest findings on post-infarct remodeling, new potential therapeutic targets are arising to halt the progression of disease. In this review, we evaluate the results obtained from four new therapeutic strategies: in this part we evaluate gene therapy and novel aspect of stem cells therapy in remodeling; in the second part we will investigate, micro-RNA, posttranslational modification and microspheres based therapy.

RESUMO

AIMS: The suppressors of cytokine signalling (SOCS) are identified inhibitors of cytokine and growth factor signalling that act via the Janus kinase (JAK) signal transducers and activators of transcription (STAT) pathways. Aberrant JAK/STAT signalling promotes progression from hypertrophy to heart failure. Little information is available concerning the role of SOCS in the transition from hypertrophy to heart failure. To this aim, we investigated the effects of SOCS1 overexpression obtained by in vivo adeno-associated gene transfer using an aortopulmonary cross-clamping technique in a chronic pressure-overload cardiac rat model. METHODS AND RESULTS: Rats were randomized into four groups: sham-operated (n = 18), aortic banding (AB) (n = 18), AB + viral vector encoding for haemoagglutinin (AB + HA, n = 16), and AB + viral vector encoding for SOCS1 (AB + SOCS1, n = 18). Echocardiographic and haemodynamic measurements were performed 15 weeks after banding. While SOCS3 was upregulated during the hypertrophic phase, SOCS1 transcript levels increased significantly between 15 and 20 weeks. Remodelling was markedly worse in AB + SOCS1, showed larger left ventricular internal dimensions (+16%), higher end-diastolic pressures (+57%) and wall stress (+45%), and reduced fractional shortening (-32%) compared with AB + HA; apoptotic rate was increased three-fold and the gp130 pathway was inhibited. Ex vivo experiments showed that mechanical stretch upregulated SOCS1 expression, which was in turn attenuated by tumour necrosis factor-α (TNF-α) inhibition. CONCLUSION: Enhanced SOCS1 myocardial signalling is associated with accelerated transition from hypertrophy to failure in an established model of pressure overload. SOCS1 may represent an attractive target for the prevention of heart failure progression.
