Biventricular electromechanical dysfunction and molecular remodeling in a rat model of advanced pulmonary arterial hypertension.

Background: Pulmonary arterial hypertension (PAH) is a severe condition characterized by elevated pulmonary arterial pressure, leading to significant morbidity and mortality. Despite ongoing research, its pathophysiology remains incompletely understood. Traditionally, PAH has been regarded as predominantly affecting the right ventricle (RV), often overlooking its potential impact on the left ventricle (LV), particularly in patients with preserved LV ejection fraction (EF).

Sex-specific cardiac electrophysiological remodeling influences the susceptibility to arrhythmias in elderly rats.

Advanced age is a well-known risk factor for cardiovascular disease (CVD), with sex differences contributing significantly to age-dependent clinical heterogeneity. The incidence of CVD increases with age in both sexes, although men and women are predisposed toward different CVDs. However, the sex-specific arrhythmogenic alterations in aged individuals are still not described in depth.

Urinary hyaluronidase activity is closely related to vasopressinergic system following an oral water load in men: a potential role in blood pressure regulation and early stages of hypertension development.

Introduction: Blood pressure (BP) regulation is a complex process involving several factors, among which water-sodium balance holds a prominent place. Arginin-vasopressin (AVP), a key player in water metabolism, has been evoked in hypertension development since the 1980s, but, to date, the matter is still controversial. Hyaluronic acid metabolism has been reported to be involved in renal water management, and AVP appears to increase hyaluronidase activity resulting in decreased high-molecular-weight hyaluronan content in the renal interstitium, facilitating water reabsorption in collecting ducts.

Incidence and risk factors for non-cardiac syncope in a cohort of patients addressing an accredited Arterial Hypertension Center: the Innocent Study.

Background: Hypotensive susceptibility in hypertensive patients could facilitate orthostatic hypotension, syncope and fall. The aim of this study was to identify incidence, clinical form, complications and risk factors for non-cardiac syncope in a cohort of hypertensive patients.

Methods: This is an observational, case-controlled, retrospective study carried out on 168 patients, evaluated at the Hypertension Center of the University Hospital of Parma (Italy).

MANP in Hypertension With Metabolic Syndrome: Proof-of-Concept Study of Natriuretic Peptide-Based Therapy for Cardiometabolic Disease.

Hypertension and metabolic syndrome frequently coexist to increase the risk for adverse cardiometabolic outcomes. To date, no drug has been proven to be effective in treating hypertension with metabolic syndrome. M-atrial natriuretic peptide is a novel atrial natriuretic peptide analog that activates the particulate guanylyl cyclase A receptor.

Pheochromocytoma-induced cardiogenic shock: A multicentre analysis of clinical profiles, management and outcomes.

Objective: There is still uncertainty about the management of patients with pheochromocytoma-induced cardiogenic shock (PICS). This study aims to investigate the clinical presentation, management, and outcome of patients with PICS.

Methods: We collected, retrospectively, the data of 18 patients without previously known pheochromocytoma admitted to 8 European hospitals with a diagnosis of PICS.

The body of evidence of late-life depression: the complex relationship between depressive symptoms, movement, dyspnea and cognition.

Background: Physical symptoms play an important role in late-life depression and may contribute to residual symptomatology after antidepressant treatment. In this exploratory study, we examined the role of specific bodily dimensions including movement, respiratory functions, fear of falling, cognition, and physical weakness in older people with depression.

Methods: Clinically stable older patients with major depression within a Psychiatric Consultation-Liaison program for Primary Care underwent comprehensive assessment of depressive symptoms, instrumental movement analysis, dyspnea, weakness, activity limitations, cognitive function, and fear of falling.

Age-related increases in cardiac excitability, refractoriness and impulse conduction favor arrhythmogenesis in male rats.

The effects of excitability, refractoriness, and impulse conduction have been independently related to enhanced arrhythmias in the aged myocardium in experimental and clinical studies. However, their combined arrhythmic effects in the elderly are not yet completely understood. Hence, the aim of the present work is to relate relevant cardiac electrophysiological parameters to enhanced arrhythmia vulnerability in the in vivo senescent heart.

Evidence for a Prehypertensive Water Dysregulation Affecting the Development of Hypertension: Results of Very Early Treatment of Vasopressin V1 and V2 Antagonism in Spontaneously Hypertensive Rats.

In addition to long-term regulation of blood pressure (BP), in the kidney resides the initial trigger for hypertension development due to an altered capacity to excrete sodium and water. Betaine is one of the major organic osmolytes, and its betaine/gamma-aminobutyric acid transporter (BGT-1) expression in the renal medulla relates to interstitial tonicity and urinary osmolality and volume. This study investigated altered water and sodium balance as well as changes in antidiuretic hormone (ADH) activity in female spontaneously hypertensive (SHR) and normotensive Wistar Kyoto (WKY) rats from their 3-5 weeks of age (prehypertensive phase) to SHR's 28-30 weeks of age (established hypertension-organ damage).

Artificial Intelligence Supports Decision Making during Open-Chest Surgery of Rare Congenital Heart Defects.

The human right ventricle is barely monitored during open-chest surgery due to the absence of intraoperative imaging techniques capable of elaborating its complex function. Accordingly, artificial intelligence could not be adopted for this specific task. We recently proposed a video-based approach for the real-time evaluation of the epicardial kinematics to support medical decisions.

Antidepressant Drugs Effects on Blood Pressure.

Individuals suffering from depressive disorders display a greater incidence of hypertension compared with the general population, despite reports of the association between depression and hypotension. This phenomenon may depend, at least in part, on the use of antidepressant drugs, which may influence blood pressure through different effects on adrenergic and serotoninergic pathways, as well as on histaminergic, dopaminergic, and cholinergic systems. This review summarizes extant literature on the effect of antidepressant drugs on blood pressure.

Unrecognised pheochromocytoma in pregnancy discovered through metoclopramide-triggered hypertensive emergency.

Purpose: Pheochromocytoma, a catecholamine-secreting tumour leading to neurological and cardiovascular life-threatening conditions through hypertension crisis, occurs in 0.1-0.5% of hypertensive patients, but it is extremely rare in pregnancy (0.

High renin hypertension in focal renal fibromuscular dysplasia: turn off of renin system angiotensin overactivation by renal angioplasty cured high blood pressure and quickly reversed myocardial hypertrophy.

Background Fibromuscolar dysplasia (FMD) is an idiopathic, non-atherosclerotic and non-inflammatory stenotic lesion of renal arteries causing renovascular hypertension up-regulating renin-angiotensin-aldosterone system. Case report: A 18-year-old man was referred to our Hypertension Center (Clinica e Terapia Medica) for the recent onset of hypertension, poorly controlled on calcium channel blockers, already associated to electrocardiographic and echocardiography signs of left ventricular hypertrophy and significant albuminuria (728 mg/24 h). An increased plasma renin activity (PRA), aldosterone level and a mild hypokalemia raised the suspicion of renovascular hypertension.

Mitochondrial mechanosensor in cardiovascular diseases.

The role of mitochondria in cardiac tissue is of utmost importance due to the dynamic nature of the heart and its energetic demands, necessary to assure its proper beating function. Recently, other important mitochondrial roles have been discovered, namely its contribution to intracellular calcium handling in normal and pathological myocardium. Novel investigations support the fact that during the progression toward heart failure, mitochondrial calcium machinery is compromised due to its morphological, structural and biochemical modifications resulting in facilitated arrhythmogenesis and heart failure development.

Electrolyte Disorders Induced by Antineoplastic Drugs.

The use of antineoplastic drugs has a central role in treatment of patients affected by cancer but is often associated with numerous electrolyte derangements which, in many cases, could represent life-threatening conditions. In fact, while several anti-cancer agents can interfere with kidney function leading to acute kidney injury, proteinuria, and hypertension, in many cases alterations of electrolyte tubular handling and water balance occur. This review summarizes the mechanisms underlying the disturbances of sodium, potassium, magnesium, calcium, and phosphate metabolism during anti-cancer treatment.

Posterior reversible encephalopathy syndrome in an oncological normotensive patient: evidence for a pathogenic role of concomitant low magnesium serum levels and chemotherapy treatment.

Background: Posterior reversible encephalopathy (PRES) is a rare syndrome characterized by headache, confusion, seizures, visual changes and white matter edema at radiological imaging. Its pathophysiology is not clarified and different causes, including uncontrolled hypertension, eclampsia, chemotherapy and hypomagnesemia have been suggested.

Case Report: A woman affected by stage IV breast cancer with lower extremity deep vein thrombosis treated with low-molecular-weight-heparin, currently in therapy with Palbociclib/Fulvestrant (antiCDK4 and 6/estrogen receptor antagonist) but previously treated with several other chemotherapy lines (including VEGF inhibitor bevacizumab), was admitted to our Internal Medicine department because of ascites and abdominal pain.

Attitudes of Italian Psychiatrists Toward the Evaluation of Physical Comorbidities and Sexual Dysfunction in Patients With Schizophrenia. Implications for Clinical Practice.

Treatment guidelines for patients with schizophrenia recommend evaluating their risk of physical comorbidities, especially since these patients are known to have decreased life expectancy due to comorbidities. Therefore, to the authors' knowledge, this is the first national survey conducted to investigate how Italian psychiatrists deal with the risk of physical comorbidities and sexual dysfunction in patients with schizophrenia. A sample of 750 psychiatrists completed an online survey investigating their decision making about performing blood tests, clinical and instrumental examinations, and scheduling follow-up appointments in relation to the different phases of the illness and possible pharmacological side effects.

Concurrent heterozygous Von-Hippel-Lindau and transmembrane-protein-127 gene mutation causing an erythropoietin-secreting pheochromocytoma in a normotensive patient with severe erythrocytosis.

Background: Mutations of genes related to Krebs cycle enzymes, kinases or to pseudohypoxic signaling pathways, including Von-Hippel-Lindau (VHL) and transmembrane-protein-127 predispose to pheochromocytoma and paraganglioma development. Homozygous loss of function mutation of VHL (VHL 598C>T) gene can associate with polycythemia because of an altered hypoxia sensing.

Patient: A 19-year-old normotensive man presented with headache, fatigue associated with severe erythrocytosis (hematocrit 76%), high hemoglobin (25.

Atrial Natriuretic Peptide: A Molecular Target of Novel Therapeutic Approaches to Cardio-Metabolic Disease.

Atrial natriuretic peptide (ANP) is a cardiac hormone with pleiotropic cardiovascular and metabolic properties including vasodilation, natriuresis and suppression of the renin-angiotensin-aldosterone system. Moreover, ANP induces lipolysis, lipid oxidation, adipocyte browning and ameliorates insulin sensitivity. Studies on ANP genetic variants revealed that subjects with higher ANP plasma levels have lower cardio-metabolic risk.

Non-steroidal anti-inflammatory drug effects on renal and cardiovascular function: from physiology to clinical practice.

Excessive or inappropriate use of non-steroidal anti-inflammatory drugs can affect cardiovascular and renal function. Non-steroidal anti-inflammatory drugs, both non-selective and selective cyclooxygenase 2 inhibitors, are among the most widely used drugs, especially in the elderly, with multiple comorbidities. Exposition to a polypharmacy burden represents a favourable substrate for the onset of non-steroidal anti-inflammatory drug-induced deleterious effects.

Physical exercise for late-life depression: Effects on symptom dimensions and time course.

Background: Physical exercise is increasingly recognized as a treatment for major depression, even among older patients. However, it is still unknown which depressive symptoms exercise affects most, (e.g.

Lung ultrasound in internal medicine: A bedside help to increase accuracy in the diagnosis of dyspnea.

Background: Dyspnea is one of the most frequent causes of admission in Internal Medicine wards, leading to a sizeable utilization of medical resources.

Study Design And Methods: The role of bedside lung ultrasound (LUS) was evaluated in 130 consecutive patients (age: 81±9years), in whom blindly collected LUS results were compared with data obtained by clinical examination, medical history, blood analysis, and chest X-ray. Dyspnea etiology was classified as "cardiac" (n=80), "respiratory" (n=36) or "mixed" (n=14), according to the discharge diagnosis (congestive heart failure either alone [n=80] or associated with pneumonia [n=14], pneumonia [n=24], and obstructive disventilatory syndrome [n=12]).
