RESUMEN

The Italian Network on Congestive Heart Failure (IN-CHF) project, later known as IN-HF Online, was launched in 1995 to provide the Italian cardiology community with a digital tool, standardized across the country, for managing outpatients with heart failure (HF), that enabled the creation of a database for clinical, educational and scientific purposes. During its almost three decades of activity, this observational research program has achieved highly positive scientific results. Indeed, IN-HF fostered professional relationships among individuals working in different centers, established a cultural network for the care of HF patients, periodically updated on the scientific advances, and allowed the assessment of several clinical, epidemiological, and prognostic features. These findings have been published in numerous national and international journals, as summarized in the present overview.

RESUMEN

BACKGROUND: Available data on the clinical characteristics and prognosis of patients with heart failure (HF) due to dilated cardiomyopathy (DCM) derive mainly from tertiary care centres for cardiomyopathies or from drug trial sub-studies, which may entail a referral bias. METHODS: From 2008 to 2021, we enrolled in a nationwide HF Registry 1886 DCM patients and 3899 with ischemic heart disease (IHD). RESULTS: Patients with DCM were younger, more often female, had more commonly recent onset HF, left bundle branch block, and showed higher LV end-diastolic volume and lower LVEF than IHD. With respect to IHD, DCM patients received more often mineralocorticoid receptor antagonists, renin angiotensin system inhibitors and betablockers, the latter more commonly at doses ≥50% of target, and triple guideline-directed medical therapy (GDMT) (adjusted OR 1.411, 95% CI 1.247-1.595, p < .0001). During one-year follow-up, 819 patients (14.2%) died or were hospitalized for HF [187 (9.9%) DCM, 632 (16.2%) IHD]; DCM was associated with lower risk of the combined end-point (adjusted HR 0.745, 95% CI 0.625- 0.888, p = .0011). Among the 1954 patients with 1-year echocardiograms available, 1483 had LVEF≤40% at baseline; of these,166 (30.6%) DCM and 165 (17.5%) IHD improved their LVEF to >40% (p < .0001). DCM aetiology was associated with higher likelihood of LVEF improvement (adjusted OR 1.722, 95% CI 1.328 -2.233, p < .0001). CONCLUSIONS: DCM patients have a different clinical profile, greater uptake of GDMT and better outcomes than IHD subjects. A comprehensive management approach is needed to further address the risk of unfavorable outcomes in DCM.

RESUMEN

Pulmonary hypertension (PH) is a common complication of diseases affecting the left heart, mostly found in patients suffering from heart failure. Left atrial hypertension is the initial driver of post-capillary PH. However, several mechanisms may lead in a subset of patients to structural changes in the pulmonary vessels with development of a pre-capillary component. The right ventricle may be frequently affected, leading to right ventricular failure and a worse outcome. The differential diagnosis of PH associated with left heart disease vs pulmonary arterial hypertension (PAH) is challenging in patients with cardiovascular comorbidities, risk factors for PAH and/or a preserved left ventricular ejection fraction. Multidimensional clinical phenotyping is needed to identify patients in whom hemodynamic confirmation is deemed necessary, that may be completed by provocative testing in the cath lab. In contrast with PAH, management of PH associated with left heart disease should focus on the treatment of the underlying condition. There is currently no approved therapy for PH associated with left heart disease: some PAH-specific treatments have led to an increase in adverse events in these patients.

RESUMEN

Cardiac magnetic resonance (CMR) imaging has progressively become part of the imaging methods recommended in patients with heart failure. CMR represents the gold standard for assessing volumes, function, biventricular kinetics and providing tissue characterization through scans with and without contrast medium. In patients with heart failure with reduced ejection fraction (HFrEF) and ischemic dilated cardiomyopathy, CMR allows to search for viability, accurately estimate volumes and ejection fraction. It can assess scar extent for predicting response to cardiac resynchronization therapy and for establishing an indication for implanting a defibrillator in borderline cases. In patients with HFrEF and non-ischemic dilated cardiomyopathy, CMR helps to identify specific etiological subgroups and to estimate the arrhythmic risk beyond ejection fraction. In patients with heart failure with preserved ejection fraction, CMR offers the possibility of diagnosing specific phenotypes, including sarcomeric hypertrophic cardiomyopathy, amyloidosis or Fabry disease, and adds prognostic information. Both clinical and scientific interest in this imaging method is constantly expanding; the clinicians dealing with heart failure cannot fail to know the technique, the indications and all the potential that CMR can offer.

RESUMEN

Heart failure with improved ejection fraction (HFimpEF) represents a nosological entity that has recently been recognized and has little evidence from the literature. Available data indicate an increasing incidence of this patient group, consistent with the progressive improvement and implementation of medical therapy of heart failure with reduced ejection fraction (HFrEF). Furthermore, it is important to underline that the therapy itself should not be suspended after ejection fraction recovery, to avoid the recurrence of worse systolic dysfunction and patient outcomes. Only recently a randomized clinical study has been published, which enrolled also this patient subgroup, the DELIVER trial. Other data will soon become available, given the interest of the scientific community for this subgroup of patients, whose best management remains controversial. Since many studies suggest that the probability of myocardial recovery in HFrEF patients might be as high as 40%, depending on the case series taken into account, whereas the time to recovery might even be 12 months, the appropriate timing of device implantation, such as the defibrillator, in this setting deserves careful consideration.

RESUMEN

Pharmacotherapy of chronic heart failure with mildly reduced (HFmrEF) and preserved ejection fraction (HFpEF) remains challenging. We aimed to assess whether combined neuro-humoral modulation (NHM) (renin−angiotensin system inhibitors, betablockers, mineralocorticoid receptor antagonists) was differentially associated with outcome according to phenotype and age groups. Between 1999 and 2018 we recruited in a nationwide cardiology registry 4707 patients (HFmrEF n = 2298, HFpEF n = 2409) from three age groups: <65, 65−79 and 80+ years old. We analyzed clinical characteristics and 1 year all-cause mortality/cardiovascular hospitalization according to none/single, any double, or triple NHM. Prescription rates of no/single and triple NHM were 25.1% and 26.7% for HFmrEF; 36.5% and 17.9% for HFpEF patients, respectively. Older age was associated with higher prescription of no/single NHM in HFmrEF (ptrend = 0.001); the reverse was observed among HFpEF (ptrend = 0.005). Triple NHM increased over time in both phenotypes (all p for trend < 0.0001). Compared to no/single NHM, triple, but not double, NHM was associated with better outcomes in both HFmrEF (HR 0.700, 95%CI 0.505−0.969, p = 0.032) and HFpEF (HR 0.700, 95%CI 0.499−0.983, p = 0.039), with no interaction between NHM treatment and age groups (p = 0.58, p = 0.80, respectively). In a cardiology setting, among HF outpatients with EF > 40%, triple NHM treatment increased over time and was associated with better patient outcomes.

RESUMEN

For prostate cancer (PCa) biochemical recurrence (BCR), the primarily suggested imaging technique by the European Association of Urology (EAU) guidelines is prostate-specific membrane antigen (PSMA) positron emission tomography/computer tomography (PET/CT). Indeed, the increased detection rate of PSMA PET/CT for early BCR has led to a fast and wide acceptance of this novel technology. However, PCa is a very heterogeneous disease, not always easily assessable with the highly specific PSMA PET with around 10% of cases occuring without PSMA expression. In this paper, we present the case of a patient with PCa BCR that resulted negative on [68Ga]Ga-PSMA-11 PET/CT, but positive on [18F]Fluoromethylcholine (Choline) PET/CT.

RESUMEN

Fractal properties in time series of human behavior and physiology are quite ubiquitous, and several methods to capture such properties have been proposed in the past decades. Fractal properties are marked by similarities in statistical characteristics over time and space, and it has been suggested that such properties can be well-captured through recurrence quantification analysis. However, no methods to capture fractal fluctuations by means of recurrence-based methods have been developed yet. The present paper takes this suggestion as a point of departure to propose and test several approaches to quantifying fractal fluctuations in synthetic and empirical time-series data using recurrence-based analysis. We show that such measures can be extracted based on recurrence plots, and contrast the different approaches in terms of their accuracy and range of applicability.

RESUMEN

Background: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are highly effective in improving glycaemic control either as monotherapy or in combination with other hypoglycaemic drugs, and have low incidence of side effects, such as hypoglycaemia, nausea and weight gain, thus increasing patients' adherence to therapy. Methods: In this review we report the most recent studies demonstrating the beneficial effects of GLP-1RAs on renal outcomes, and also discuss the direct and indirect mechanisms through which they confer kidney protection. Finally, we discuss the metabolic and anti-inflammatory effects of GLP-1RAs in diabetic patients with COVID-19 disease. Results: GLP-1RAs have a nephroprotective action, which is expressed through both indirect (improvement of blood pressure and glycaemic control, weight loss) and direct (restoration of normal intrarenal haemodynamics, prevention of ischaemic and oxidative damage) effects. They have shown also metabolic and anti-inflammation beneficial effects in patients with COVID-19 disease. Conclusions: GLP-1RAs prevent albuminuria and slow the decline of renal function towards end stage renal disease in patients with diabetic kidney disease. They might be an opportunity to break the typical inflammation processes of COVID-19 disease.

RESUMEN

The process by which infants move from liquid feeding to caregiver-assisted spoon feeding of semi-solid food is quite a dramatic transition. In previous studies, we observed that in the weeks after the introduction to solid food, mother-infant dyads showed increased co-regulation and synchronization of their respective feeding behaviors (e.g. offering food, accepting/refusing, timing). Learning this new way of feeding and eating requires that infants coordinate their position and movements with the complementary position and movements of the caregiver. The present study augments the category-based analysis of this co-regulation by the analysis of coupling in the dyads based on automatically extracted movement data. Previously collected video data from 10 mother-infant dyads were re-analyzed for the purpose of this study. Movement trajectories of mother's hand and infant's face were obtained by applying an automatic movement detection algorithm (TLD, Kalal et al., 2012; for applications to mother-infant interactions see López Pérez et al., 2017). Coordination was assessed by the method of Diagonal Cross Recurrence Profiles (DCRP), which expresses the degree of synchronization at different time lags. Profiles for each dyad from two different occasions --with one visit in the first week of solid feeding and one approximately 4-5 weeks later-- were compared. The results showed that, on average, most synchronization occurred in the first visit at lag 0. In the second visit there was an average delay in synchronization of about 1 s, with leading behavior starting from the infant. This suggests that the coordination was initially closely synchronized and became somewhat looser over time. Possibly, infants have begun to anticipate and guide the feeding movements enacted by the mother. However, our findings underline the idiosyncratic and complex nature of co-regulation of movements during the introduction of solid food. Whereas some dyads showed signs of increased organization, others seemed to disorganize, re-organize, or showed no organization at all. Many (interacting) factors --both individual and contextual-- may be responsible for the observed differences between dyads. Further research is needed to understand why specific synchronization pathways emerge and whether and how these might relate both to later feeding and eating and to the emergent patterns of participation.

RESUMEN

AIMS: To assess adherence to guideline recommendations among a large network of Italian cardiology sites in the management of acute and chronic heart failure (HF) and to evaluate if an ad-hoc educational intervention can improve their performance on several pharmacological and non-pharmacological indicators. METHODS AND RESULTS: BLITZ-HF was a cross-sectional study based on a web-based recording system with pop-up reminders on guideline recommendations used during two 3-month enrolment periods carried out 3 months apart (Phase 1 and 3), interspersed by face-to-face macro-regional benchmark analyses and educational meetings (Phase 2). Overall, 7218 patients with acute and chronic HF were enrolled at 106 cardiology sites. During the enrolment phases, 3920 and 3298 patients were included, respectively, 84% with chronic HF and 16% with acute HF in Phase 1, and 74% with chronic HF and 26% with acute HF in Phase 3. At baseline, adherence to guideline recommendations was already overall high for most indicators. Among acute HF patients, an improvement was obtained in three out of eight indicators, with a significant rise in echocardiographic evaluation. Among chronic HF patients with HF and preserved or mid-range ejection fraction, performance increased in two out of three indicators: creatinine and echocardiographic evaluations. An overall performance improvement was observed in six out of nine indicators in ambulatory HF with reduced ejection fraction patients with a significant increase in angiotensin receptor-neprilysin inhibitor prescription rates. CONCLUSIONS: Within a context of an already elevated level of adherence to HF guideline recommendations, a structured multifaceted educational intervention could be useful to improve performance on specific indicators. Extending this approach to other non-cardiology healthcare professionals, who usually manage patients with HF, should be considered.

RESUMEN

INTRODUCTION AND OBJECTIVES: Octogenarians represent the most rapidly expanding population segment in Europe. The prevalence of heart failure (HF) in this group exceeds 10%. We assessed changes in clinical characteristics, therapy, and 1-year outcomes over 2 decades in chronic HF outpatients aged ≥ 80 years enrolled in a nationwide cardiology registry. METHODS: We included 2520 octogenarians with baseline echocardiographic ejection fraction measurements and available 1-year follow-up, who were recruited at 138 HF outpatient clinics (21% of national hospitals with cardiology units), across 3 enrolment periods (1999-2005, 2006-2011, 2012-2018). RESULTS: At recruitment, over the 3 study periods, there was an increase in age, body mass index, ejection fraction, the prevalence of obesity, diabetes, dyslipidemia, pre-existing hypertension, and atrial fibrillation history. The proportion of patients with preserved ejection fraction rose from 19.4% to 32.7% (P for trend <.0001). Markers of advanced disease became less prevalent. Prescription of beta-blockers and mineralocorticoid receptor antagonists increased over time. During the 1-year follow-up, 308 patients died (12.2%) and 360 (14.3%) were admitted for cardiovascular causes; overall, 591 (23.5%) met the combined primary endpoint of all-cause mortality or cardiovascular hospitalization. On adjusted multivariable analysis, enrolment in 2006 to 2011 (HR, 0.70; 95%CI, 0.55-0.90; P=.004) and 2012 to 2018 (HR, 0.61; 95%CI, 0.47-0.79; P=.0002) carried a lower risk of the primary outcome than recruitment in 1999 to 2005. CONCLUSIONS: Among octogenarians, over 2 decades, risk factor prevalence increased, management strategies improved, and survival remained stable, but the proportion hospitalized for cardiovascular causes declined. Despite increasing clinical complexity, in cardiology settings the burden of hospitalizations in the oldest old with chronic HF is declining.

RESUMEN

Since their introduction as antidiabetic drugs, SGLT2 inhibitors (SGLT2i) have come a long way, proving to be beneficial on cardiovascular and renal outcomes independently of diabetes status. The benefits go far beyond glycemic control, and both the cardio- and nephroprotection are underpinned by diverse mechanisms. From the activation of tubule glomerular feedback and the consequent reduction in hyperfiltration to the improvement of hypoxia and oxidative stress in the renal cortex, SGLT2i have also been shown to inhibit hepcidin and limit podocyte damage. Likewise, they improve cardiac metabolism and bioenergetics, and reduce necrosis and cardiac fibrosis and the production of adipokines, cytokines, and epicardial adipose tissue mass. In terms of outcomes, the efficacy has been demonstrated on blood pressure control, BMI, albuminuria, stroke, heart disease, and mortality rate due to cardiovascular events. Patients with chronic kidney disease and proteinuria, with or without diabetes, treated with some SGLT2i have a reduced risk of progression. The analysis of subgroups of individuals with specific diseases such as IgA nephropathy has confirmed this solid effect on renal outcomes. Given these overarching activities on such a broad pathophysiological background and the favorable safety profile that goes with the use of SGLT2i, it is now certain that they are changing our approach to clinical interventions for important outcomes with an impressive impact.

RESUMEN

BACKGROUND: Celiac disease (CD) is still underestimated. To close this diagnostic gap, the Health Sicilian Authorities have constituted the "Sicilian Network for CD". AIMS: A) To verify the quality of the current diagnostic approach using the data sheet of the Network. B) To evaluate the clinical, serologic and histologic data of new diagnoses in the context of the Network METHODS: We retrospectively evaluated the data collection forms of 369 patients with CD from three Centers within the Sicilian Network. All the Centers used a standard data collection form. RESULTS: A non-classical CD presentation was more frequent than the classical one, anemia being the most frequent symptom (50%). An IBS-like presentation was found in one third of the cases. A diagnostic delay of about 9 years following the onset of symptoms was observed. Almost half of the patients had not undergone multiple duodenal biopsies; unrecommended CD serology assays were prescribed in 59.9% of the cases. CONCLUSIONS: The regional data sheets allowed an assessment of the diagnostic delay. We recorded a frequent use of unrecommended tests prescribed before referring patients to the regional Centers. Updating the education of physicians regarding CD is necessary to avoid unwarranted health expenditure.

RESUMEN

AIMS: Ageing and comorbidities are increasing frailty/complexity of heart failure (HF) patients globally. We assessed evolving trends over two decades according to patients' age and time of recruitment in a nationwide cardiology setting in Italy. METHODS AND RESULTS: Chronic HF outpatients recruited between 1999 and 2018 (N = 14,823) were divided into 3 cohorts: 1999-2005 (N = 5404); 2006-2011 (N = 3971); 2012-2018 (N = 5448). We analyzed temporal changes in clinical characteristics, therapies, and outcome (1-year all-cause mortality/cardiovascular hospitalization), overall and by age group: <65 (n = 5465); 65-79 (n = 6838); ≥80 (n = 2520) years old. Across enrolment epochs, comorbidities (atrial fibrillation, hypertension, obesity) increased by both epoch/age groups (p < 0.001), whereas the prevalence of ischemic etiology declined among patients ≥65 years (p = 0.05). Accordingly, the preserved LVEF phenotype (HFpEF) increased in all age categories (p < 0.001) over time. Moreover, the use of betablockers, mineralocorticoid-receptor antagonists and loop-diuretics rose by enrolment epoch in all age groups (p < 0.05). In parallel with these epidemiologic/treatment changes, age-adjusted survival free from cardiovascular hospitalization improved over time (p < 0.0001). However, divergent trends in the end-point components were apparent according to age groups: mortality decreased in patients<80 years, although hospitalizations remained stable in the youngest group, while subjects ≥65 years were less likely to be admitted for cardiovascular causes (all p < 0.005). CONCLUSIONS: Over two decades in a cardiology outpatient setting, the prevalence of comorbid HFpEF increased in all age categories. Mortality improved among patients<80 years and cardiovascular hospitalizations decreased in patients≥65 years. These findings point to the value of cardiologist' input in the management of adult chronic HF patients at all ages.

RESUMEN

Dialysis adequacy and a state of "eunutrition" are two essential elements to consider in the evaluation of patient undergoing dialysis treatment. Dialysis inadequacy is often associated with malnutrition, and the combination of these two factors significantly worsens the prognosis. In the following monocentric and prospective study, the correlation between nutritional markers and dialytic adequacy was tested in a cohort of patients permanently followed by the peritoneal dialysis clinic, followed consistently for two years. It was therefore evaluated if modification of dialysis therapy, aimed to reach adequacy parameters, could simultaneously improve metabolic parameters. Although there were no frankly malnourished patients, the group of "inadequate" patients had a significantly lower nPCR value. In this same group, after about 6 months, therapeutic measures adopted allowed an overall improvement in Kt/V and nPCR, with other nutritional parameters (such as body weight, albumin, pre-albumin, total cholesterolemia) remaining stable. At the end of the follow-up period the Kt/V of the "inadequate" (<1.7) was higher ​​than the baseline, reaching statistical significance at the 12th and 24th months. Early identification of a dialysis inadequacy, therefore, allowed the execution of therapeutic changes necessary to achieve a lasting improvement in "adequate" replacement therapy, and a temporary improvement in the patient's nutritional status. Suddenly, despite the persistent improvement of the Kt/V there was a new reduction of the nPCR.

RESUMEN

Optimal glycemic control in diabetic patients remains a difficult goal to achieve. Hypoglycemia, nausea and weight gain can compromise the patients' adherence to antidiabetic therapy over time. GLP-1 receptor agonists have been shown to improve glycemic control and reduce the incidence of side effects both when used in monotherapy and in combination with other hypoglycemic drugs. The growing interest of nephrologists in GLP-1 receptor agonists derives from numerous studies showing that not only they positively affect traditional cardiovascular risk factors, but also exert a protective effect on renal function regardless of their hypoglycemic effects, thus delaying the development and progression of diabetic nephropathy. The aim of this paper is to review the latest evidence on pharmacokinetics and pharmacodynamics and the direct and indirect mechanisms through which GLP-1 receptor agonists confer nephroprotection, improving the renal outcomes of diabetic patients.

RESUMEN

We record a new ichnosite bearing dinosaur tracks from the mid-Cretaceous (Aptian? -Cenomanian) of Brazil. The Fazenda dos Pingos ichnosite is situated within a sandstone pavement of the Açu Formation (Açu 3 unit) from the Potiguar Basin in the State of Rio Grande do Norte. This is a small ichnofauna, with only a few individual isolated tracks. One specimen is unequivocally attributed to a large sauropod and another to an ornithopod. Two other specimens represent poorly preserved tracks assigned to sauropods. This is the first record of dinosaur tracks from the Potiguar Basin and from the Rio Grande do Norte State.

RESUMEN

Heart failure (HF) is still characterized by high mortality rates, despite the progress achieved in terms of treatment options. With regard to the treatment of HF with reduced ejection fraction (HFrEF), the 2016 European Society of Cardiology guidelines included in the therapeutic algorithm the angiotensin receptor-neprilysin inhibitor class, whose efficacy in modifying patient prognosis has been extensively proven in many clinical studies. Sacubitril/valsartan, the only representative of this drug class, can effectively affect the natural history of HF, thus reducing cardiovascular mortality (sudden death and death due to worsening cardiac function), total mortality, as well as first and recurrent hospitalization events, by improving renal function, cardiac remodeling, functional capacity and the patient's health-related quality of life.The purpose of this article is to analyze the different phases of the journey of patients with HFrEF (first general practitioner consultation; admission to the emergency department and subsequent hospitalization; referral to a specialist HF clinic) and promotion of a networking approach involving the general practitioner, the hospital and the HF specialist based on common pre-defined diagnostic and therapeutic protocols, that meets patient needs at all stages of the disease (case-specific dosing assessment, drug titration before follow-up and prevention of adverse events).

RESUMEN

Epidemiological data show an increasing diffusion of diabetes mellitus worldwide. In the diabetic subject, the risk of onset of chronic kidney disease (CKD) and its progression to the terminal stage remain high, despite current prevention and treatment measures. Although SGLT2 inhibitors have been approved as blood glucose lowering drugs, they have shown unexpected and surprising cardioprotective and nephroprotective efficacy. The multiple underlying mechanisms of action are independent and go beyond glycemic lowering. Hence, it has been speculated to extend the use of these drugs also to subjects with advanced stages of CKD, who were initially excluded because of the expected limited glucose-lowering effect. Non-diabetic patients could also benefit from the favorable effects of SGLT2 inhibitors: subjects with renal diseases with different etiologies, heart failure, high risk or full-blown cardiovascular disease.
