How to reduce erroneous Emergency Department admissions for the frail elderly.

Background: Readmission after a first hospitalization is a common occurrence. It may be due to incomplete treatment, poor care for underlying problems or reflect bad coordination with health services at the time of discharge. The aim of this study was to identify the factors and classify the pathologies that expose elderly patients to erroneous access to the Emergency/Urgency Department (EUD).

Consensus paper on postural dysfunction: recommendations for prevention, diagnosis and therapy.

Good fundamentals of posture and balance are essential for the efficient performance of both simple daily tasks and more complex movement patterns. In particular, postural balance is the ability to keep the body in equilibrium and to regain balance after the shift of body segments: postural control mechanisms of integration of the visual, vestibular and foot afferential channels contribute to this. This document provides recommendations based on scientific evidence, clinical practice, and consensus between experts concerning the prevention, diagnosis, and treatment of postural dysfunction at the three stages of life as the developmental age, adult age, and old age > 65 years and follows the "National Guidelines on Classification and Measuring of Posture and its Dysfunctions" per the Italian Ministry of Health (December 2017).

Unusual solution to abdominal pain with contrast enhanced ultrasound.

Splenic infarction might be the symptom onset of an important underlying disease. The possibility of splenic infarction must be inserted into differential diagnosis in all those patients who have pain in the upper left quadrant and/or on the left flank. When faced with a case of splenic infarction in a patient who has flown or climbed to high altitudes, it is appropriate to consider the possibility of an haemoglobinopathy.

Following Lives Undergoing Change (Flux) study: Implementation and baseline prevalence of drug use in an online cohort study of gay and bisexual men in Australia.

Background: Drug use among gay and bisexual men (GBM) is higher than most populations. The use of crystal methamphetamine, erectile dysfunction medication (EDM), and amyl nitrite have been associated with sexual risk behaviour and HIV infection among gay and bisexual men (GBM).

Objective: This paper describes an online prospective observational study of licit and illicit drug use among GBM and explores baseline prevalence of drug use in this sample.

Which method is best for an early accurate diagnosis of acute heart failure? Comparison between lung ultrasound, chest X-ray and NT pro-BNP performance: a prospective study.

Acute heart failure is a common condition among adults presenting with dyspnea in the Emergency Department (ED), still the diagnosis is challenging as objective standardized criteria are lacking. First line work-up, other then clinical findings, is nowadays made with lung ultrasound imaging study, chest X-ray study and brain natriuretic peptide (BNP) level determination; however, it is not clear which is the best diagnostic test to be used and whether there is any real benefit for clinical judgement. We set up this study to compare the performances of these three diagnostic tools; furthermore, we combined them to find the best possible approach to dyspneic patients.

Duplex ultrasound in the early diagnosis of acute mesenteric ischemia: a longitudinal cohort multicentric study.

Objective: Acute mesenteric ischemia (AMI) is a life-threatening condition requiring time-dependent treatment; thus, early recognition may improve outcomes. We hypothesized that clinician-performed mesenteric vessels duplex ultrasound (DUS) could facilitate early identification of patients with AMI in high-risk patients presenting with abdominal pain.

Methods: This was a single-operator, observational, prospective cohort study.

Energy consumption of ProTaper Next X1 after glide path with PathFiles and ProGlider.

Introduction: Instrument failure caused by excessive torsional stress can be controlled by creating a manual or mechanical glide path. The ProGlider single-file system (Dentsply Maillefer, Ballaigues, Switzerland) was recently introduced to perform a mechanical glide path. This study was designed to compare the effect of a glide path performed with PathFiles (Dentsply Maillefer) and ProGlider on torque, time, and pecking motion required for ProTaper Next X1 (Dentsply Maillefer) to reach the full working length in simulated root canals.

Microvascular abnormalities in Rett syndrome.

Rett syndrome (RTT) is a post-natal neurological disorder that represents the second most common cause for mental retardation. The presence of cold hands and feet, and blue, a feature frequently observed in these patients, is one of the non-neurological phenotypes that characterizes RTT, up to now not well explained. We have performed videocapillaroscopy in subjects affected by Rett syndrome.

Cranial osteolytic metastases as the only recurrence of gastric carcinoma.

The purpose of this case report is to increase the knowledge about bone metastatic pattern in gastric cancer. A 59-year-old man presented with headache three years after a total gastrectomy for signet-ring cell carcinoma. Head computed tomography and magnetic resonance imaging showed multiple osteolytic lesions of the cranial vault and base, consistent with metastatic or haematological disease.

Bosentan treatment for Raynauds phenomenon and skin fibrosis in patients with Systemic Sclerosis and pulmonary arterial hypertension: an open-label, observational, retrospective study.

Raynaud?s phenomenon (RP) and cutaneous fibrosis are the distinctive manifestations of scleroderma, in which Endothelin-1 plays a fundamental pathogenetic role. Bosentan, an Endothelin-1 receptor antagonist used for the treatment of pulmonary arterial hypertension, retards the beginning of new sclerodermic digital ulcers (DU). This open-label, observational, retrospective study verified the effect of Bosentan on RP and skin fibrosis in sclerodermic outpatients affected by pulmonary arterial hypertension without DU.

Pro/Anti-inflammatory cytokine imbalance in postischemic left ventricular remodeling.

Objectives: Cytokines play an important role in left ventricular remodeling consequent to myocardial ischemia. The aim of this study was to correlate cytokine production and lymphocyte apoptosis to post-ischemic left ventricular remodeling in patients affected by acute myocardial infarction (AMI) undergoing primary cutaneous angioplasty (PCI).

Methods: In 40 patients, affected by AMI and undergoing PCI, we evaluated peripheral blood mononuclear cells (PBMCs), tumor necrosis factor-alpha (TNF-alpha) and interleukin 10 (IL10) production and apoptosis on day 1, day 3, day 7, 1 month and 6 months after PCI.

Early vs late tracheotomy for prevention of pneumonia in mechanically ventilated adult ICU patients: a randomized controlled trial.

Context: Tracheotomy is used to replace endotracheal intubation in patients requiring prolonged ventilation; however, there is considerable variability in the time considered optimal for performing tracheotomy. This is of clinical importance because timing is a key criterion for performing a tracheotomy and patients who receive one require a large amount of health care resources.

Objective: To determine the effectiveness of early tracheotomy (after 6-8 days of laryngeal intubation) compared with late tracheotomy (after 13-15 days of laryngeal intubation) in reducing the incidence of pneumonia and increasing the number of ventilator-free and intensive care unit (ICU)-free days.

Cardiac dysautonomia and arterial distensibility in essential hypertensives.

Introduction: The central nervous system plays an important role in the regulation of blood pressure: the sympathetic nervous system may be a primary contributor to the development of some forms of essential hypertension. Hypertension is also associated with reduced distensibility of large arteries. The aim of our study is the evaluation of a correlation between cardiac dysautonomia (evaluated by means of heart rate variability [HRV]) and altered artery distensibility (evaluated by means of measurement of the time interval from the onset of the QRS wave and the detection of the last Korotkoff sound [QKD interval]).

Genetic influence in antithrombotic actions of atorvastatin in hypercholesterolaemia.

Background: Recent data indicate that statins could offer coronary artery disease (CAD) benefit even by mechanisms beyond lipid lowering. Genetic influence has been shown for some antithrombotic actions of statins via oxidized-low-density lipoprotein cholesterol (ox-LDL) receptors and nitric oxide synthase (NOS) activity modulation. The present study was designed to evaluate the influence of ox-LDL lectin-like receptor-1 (LOX-1) and NOS polymorphisms in the incidence of cardiovascular events in pure hypercholesterolaemic subjects during statin treatment.

Brain natriuretic peptide and other risk markers for outcome assessment in patients with non-ST-elevation coronary syndromes and preserved systolic function.

Several emerging cardiac markers constitute strong predictors among patients with coronary artery disease. In particular, brain natriuretic peptide (BNP), troponin T (TnT), and C-reactive protein (CRP) are related to increased risk of recurrent ischemic events and death. However, little is known about the utility of these biomarkers in combination.

Lectin-like oxidized-LDL receptor-1 (LOX-1) polymorphisms influence cardiovascular events rate during statin treatment.

Background: Oxidized-LDL (ox-LDL) are involved in atherothrombosis by induction of endothelial dysfunction and thrombosis. The specific receptor lectin-like oxidized-LDL receptor-1 (LOX-1) is expressed in endothelial cells, monocytes and platelets. LOX-1 gene allelic variants (3'UTR/T) have been related with cardiovascular events and reduced anti-platelet activity induced by statins.

3'UTR/T polymorphism of lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is associated with modified anti-platelet activity of atorvastatin in hypercholesterolemic subjects.

Oxidized-low density lipoproteins (ox-LDL) and the specific receptor LOX-1 are involved in atherogenesis and atherothrombosis. LOX-1 downregulation is associated with the anti-platelet action of atorvastatin. 3'UTR/T LOX-1 polymorphism has been associated with increased risk of coronary artery disease.

Different effect of statins on platelet oxidized-LDL receptor (CD36 and LOX-1) expression in hypercholesterolemic subjects.

Hydroxymethyl-glutaryl-CoA-reductase inhibitors (statins) reduce cardiovascular mortality by decreasing cholesterol as well as by non-lipid-related actions. Oxidized low-density lipoproteins (ox-LDL) are pro-atherogenic molecules and potent platelet agonists. CD36 and lectin-like ox-LDL receptor-1 (LOX-1) are specific ox-LDL receptors also expressed in platelets.

Structural and functional abnormality of systemic microvessels in cardiac syndrome X.

Background And Aim: Microvascular damage of coronary bed has been considered the main pathogenetic factor of cardiac syndrome X (chest pain, exercise-induced ischemic ST-segment changes and angiographically normal coronary arteries). Previous studies have demonstrated that vascular abnormalities are not confined to the heart, suggesting a peripheral vascular dysfunction. On the hypothesis of a generalized microvascular disturbance in cardiac syndrome X, we performed a morphologic and functional study of systemic microcirculation in patients with syndrome X compared to normal subjects.

Atorvastatin reduces platelet-oxidized-LDL receptor expression in hypercholesterolaemic patients.

Background: Oxidized-LDL (ox-LDL) are proatherogenic and platelet-activating molecules. Atorvastatin reduces platelet activity before cholesterol-lowering action. CD36 and lectin-like oxidized-LDL receptor-1 (LOX-1) are specific ox-LDL receptors expressed also in platelets.

Plasma brain natriuretic peptide levels in coronary heart disease with preserved systolic function.

We evaluated the circulating levels of brain natriuretic peptide (BNP) in stable angina, unstable angina, and myocardial infarction relating hormone levels to extension of coronary disease and number of vessels involved after angiographic examination. We studied 86 patients consecutively undergoing angiographic coronary examination and echocardiographic evaluation for coronary heart disease. These included 15 control subjects (group 0), 21 with stable angina (group I), 26 with unstable angina (group II), and 24 with non-Q myocardial infarction (group III).

Effect of atorvastatin on different fibrinolyis mechanisms in hypercholesterolemic subjects.

Background: Hydroxymethyl-glutaryl-CoA-reductase inhibitors (statins) reduce cardiovascular events by cholesterol lowering as well as non-lipid related actions. Among them, the modulation of fibrinolysis could play a relevant role in vascular protection. Atorvastatin is able of reducing platelet activity and thrombin generation before low-density lipoprotein cholesterol (LDL-C) decrease in hypercholesterolemic subjects in which coagulation and fibrinolysis are linked by the activation of thrombin activable fibrinolysis inhibitor (TAFI).
