Potassium Intake and Bone Health: A Narrative Review.

Potassium is a cation involved in the resting phase of membrane potential. Diets rich in fresh fruit and vegetables, whole grains, dairy products, and coffee have high potassium content. The shift from a pre-agriculture diet to today's consumption has led to reduced potassium intake.

Diagnosis and treatment of Paget's disease of bone: position paper from the Italian Society of Osteoporosis, Mineral Metabolism and Skeletal Diseases (SIOMMMS).

Introduction: Paget's disease of bone is a focal skeletal disorder causing bone deformities and impairing bone quality. Despite the prevalence of asymptomatic cases is increasing, the progression of the disease can lead to invalidating complications that compromise the quality of life. Doubts on clinical and therapeutic management aspects exist, although beneficial effects of antiresorptive drugs, particularly bisphosphonates are known.

Obesity management: Attitudes and practice of Italian endocrinologists.

Introduction: Obesity is a global pandemic and is cause of serious concern in all regions of the world. It is important to raise the attention of health care professionals in order to provide early treatment of patients with obesity. Obesity management, however, varies greatly amongst endocrinologists with respect to attitudes to diagnosis and treatment.

Validation of the clinical consensus recommendations on the management of fracture risk in postmenopausal women with type 2 diabetes.

Background And Aims: Bone fragility is recognized as a complication of type 2 diabetes (T2D). However, the fracture risk in T2D is underestimated using the classical assessment tools. An expert panel suggested the diagnostic approaches for the detection of T2D patients worthy of bone-active treatment.

European Multicentric Experience With Fenestrated-branched ENDOvascular Stent Grafting After Previous FAILed Infrarenal Aortic Repair: The EU-FBENDO-FAIL Registry.

Objective: To report the mid-term outcomes of fenestrated-branched endovascular aneurysm repair (F-BEVAR) following a failed previous endovascular aneurysm repair (pEVAR) or previous open aneurysm repair (pOAR).

Methods: Data from consecutive patients who underwent F-BEVAR for pEVAR or pOAR from 2006 to 2021 from 17 European vascular centers were analyzed. Endpoints included technical success, major adverse events, 30-day mortality, and 5-year estimates of survival, target vessel primary patency, freedom from reinterventions, type I/III endoleaks, and sac growth >5 mm.

Calcium Citrate Versus Calcium Carbonate in the Management of Chronic Hypoparathyroidism: A Randomized, Double-Blind, Crossover Clinical Trial.

In hypoparathyroidism (HypoPT), calcium supplementation is virtually always required, although the disease is likely to be associated with an increased risk of nephrolithiasis. The use of calcium citrate (Ca-Cit) theoretically could have a positive impact on the nephrolithiasis risk because citrate salts are used to reduce this risk. Our objective was to evaluate the potential therapeutic advantage of Ca-Cit in comparison with calcium carbonate (CaCO ) in HypoPT, on nephrolithiasis risk factors, as well as to their ability to maintain desirable serum calcium levels.

Pathophysiology of Mild Hypercortisolism: From the Bench to the Bedside.

Mild hypercortisolism is defined as biochemical evidence of abnormal cortisol secretion without the classical detectable manifestations of overt Cushing's syndrome and, above all, lacking catabolic characteristics such as central muscle weakness, adipose tissue redistribution, skin fragility and unusual infections. Mild hypercortisolism is frequently discovered in patients with adrenal incidentalomas, with a prevalence ranging between 5 and 50%. This high variability is mainly due to the different criteria used for defining this condition.

Management and Medical Therapy of Mild Hypercortisolism.

Mild hypercortisolism (mHC) is defined as an excessive cortisol secretion, without the classical manifestations of clinically overt Cushing's syndrome. This condition increases the risk of bone fragility, neuropsychological alterations, hypertension, diabetes, cardiovascular events and mortality. At variance with Cushing's syndrome, mHC is not rare, with it estimated to be present in up to 2% of individuals older than 60 years, with higher prevalence (up to 10%) in individuals with uncontrolled hypertension and/or diabetes or with unexplainable bone fragility.

Foot Loading and Gait Analysis Evaluation of Nonarticular Tibial Pilon Fracture: A Comparison of Three Surgical Techniques.

The aim of our study was to investigate which technique among hybrid external fixation, plate and screws, and intramedullary nailing produces better outcomes in foot loading when treating type 43.A1, 43.A2, and 43.

Local Diameter, Wall Stress, and Thrombus Thickness Influence the Local Growth of Abdominal Aortic Aneurysms.

Purpose: To investigate the influence of the local diameter, the intraluminal thrombus (ILT) thickness, and wall stress on the local growth rate of abdominal aortic aneurysms.

Methods: The infrarenal aortas of 90 asymptomatic abdominal aortic aneurysm (AAA) patients (mean age 70 years; 77 men) were retrospectively reconstructed from at least 2 computed tomography angiography scans (median follow-up of 1 year) and biomechanically analyzed with the finite element method. Each individual AAA model was automatically sliced orthogonally to the lumen centerline and represented by 100 cross sections with corresponding diameters, ILT thicknesses, and wall stresses.

Impact of age and urgency on survival after thoracic endovascular aortic repair.

Objective: Elderly patients are often turned down from receiving treatment for descending thoracic aortic diseases (DTADs) because of the uncertain benefits, especially in acute settings. This study investigated the impact of old age and timing of thoracic endovascular aortic repair (TEVAR) on outcomes of DTAD in patients older than 75 years of age.

Methods: Patients from a prospective TEVAR database were dichotomized by age (75 and 80 years of age).

Arbitrary Palliation of Ruptured Abdominal Aortic Aneurysms in the Elderly is no Longer Warranted.

Objective/background: A consistent number of elderly patients with ruptured abdominal aortic aneurysms (rAAAs) are deemed unfit for repair and excluded from any treatment. The objective of this study was to examine the impact on survival of endovascular repair and open surgery with restricted turndown in acute AAA repair.

Methods: A prospective database for patients treated for rAAA was established.

The Concept of Risk Assessment and Being Unfit for Surgery.

The concept of risk assessment and the identification of surgical unfitness for vascular intervention is a particularly controversial issue today as the minimally invasive surgical population has increased not only in volume but also in complexity (comorbidity profile) and age, requiring an improved pre-operative selection and definition of high risk. A practical step by step (three steps, two points for each) approach for surgical risk assessment is suggested in this review. As a general rule, the identification of a "high risk" patient for vascular surgery follows a step by step process where the risk is clearly defined, quantified (when too "high"?), and thereby stratified based on the procedure, the patient, and the hospital, with the aid of predictive risk scores.

Safety of Carotid Revascularization in Symptomatic Patients with less than 70 Years.

Background: Age is a main risk factor for stroke and perioperative risk. This study aims to analyze the effect of age by symptomatic status in young patients receiving carotid revascularization.

Methods: Consecutive carotid revascularization procedures performed during the period 2001-2009 were reviewed.

A propensity-matched comparison for endovascular and open repair of thoracoabdominal aortic aneurysms.

Objective: The aim of this study was to investigate outcomes of patients treated with endovascular repair (ER) with the use of fenestrated and branched stent grafts or open surgery (OS) for thoracoabdominal aortic aneurysm (TAAA) in a current series of patients.

Methods: All TAAA patients undergoing repair at three centers between January 2007 and December 2014 were included in a prospective database. Patients were stratified according to treatment by ER or OS, and outcomes were compared using propensity score matching (1:1).

Summary of Evidence on Early Carotid Intervention for Recently Symptomatic Stenosis Based on Meta-Analysis of Current Risks.

Background And Purpose: This study aimed to assess the evidence on the periprocedural (<30 days) risks of carotid intervention in relation to timing of procedure in patients with recently symptomatic carotid stenosis.

Methods: A systematic literature review of studies published in the past 8 years reporting periprocedural stroke/death after carotid endarterectomy (CEA) and carotid stenting (CAS) related to the time between qualifying neurological symptoms and intervention was performed. Pooled estimates of periprocedural risk for patients treated within 0 to 48 hours, 0 to 7 days, and 0 to 15 days were derived with proportional meta-analyses and reported separately for patients with stroke and transient ischemic attack as index events.

The HIV matrix protein p17 induces hepatic lipid accumulation via modulation of nuclear receptor transcriptoma.

Liver disease is the second most common cause of mortality in HIV-infected persons. Exactly how HIV infection per se affects liver disease progression is unknown. Here we have investigated mRNA expression of 49 nuclear hormone receptors (NRs) and 35 transcriptional coregulators in HepG2 cells upon stimulation with the HIV matrix protein p17.

Effect of stentgraft model on aneurysm shrinkage in 1,450 endovascular aortic repairs.

Background: Regression of the aneurysmal sac after endovascular repair of abdominal aortic aneurysm (AAA) is an accepted indicator of aneurysm exclusion. This study evaluated the spontaneous decrease in sac diameter over a 10-year period in patients undergoing endovascular aneurysm repair (EVAR) with different stentgrafts.

Methods: 1,450 patients (mean age 73.
