Evidence based Latin American Guidelines of clinical practice on prevention, diagnosis, management and treatment of glucocorticoid induced osteoporosis. A 2022 update : This manuscript has been produced under the auspices of the Committee of National Societies (CNS) and the Committee of Scientific Advisors (CSA) of the International Osteoporosis Foundation (IOF).

Guidelines and recommendations developed and endorsed by the International Osteoporosis Foundation (IOF) are intended to provide guidance for particular pattern of practice for physicians who usually prescribe glucocorticoid (GC) therapy, and not to dictate the care of a particular patient. Adherence to the recommendations within this guideline is voluntary and the ultimate determination regarding their application should be made by the physician in light of each patient's circumstances. Guidelines and recommendations are intended to promote a desirable outcome but cannot guarantee any specific outcome.

Stem Cells in Autologous Microfragmented Adipose Tissue: Current Perspectives in Osteoarthritis Disease.

Osteoarthritis (OA) is a chronic debilitating disorder causing pain and gradual degeneration of weight-bearing joints with detrimental effects on cartilage volume as well as cartilage damage, generating inflammation in the joint structure. The etiology of OA is multifactorial. Currently, therapies are mainly addressing the physical and occupational aspects of osteoarthritis using pharmacologic pain treatment and/or surgery to manage the symptomatology of the disease with no specific regard to disease progression or prevention.

Refractory fibromyalgia.

In the medical literature, there are only a few references on refractory fibromyalgia and there is no consensus definition available on this concept. Some definitions of refractory fibromyalgia have been proposed based on the lack of response to a number of medications, and perhaps the most appropriate term is treatment-refractory fibromyalgia. To achieve the definition of treatment-refractory fibromyalgia, it is necessary to consider several previous steps, such as making sure the diagnosis has been made properly and a differential diagnosis with entities that can mimic fibromyalgia symptoms (including complete physical examination and laboratory test) has been made.

Management of glucocorticoid-induced osteoporosis.

Long-term glucocorticoid (GC) therapy is frequently indicated to treat autoimmune and chronic inflammatory diseases in daily clinical practice. Two of the most devastating untoward effects are bone loss and fractures. Doses as low as 2.

Calibration Methodology of an Edgeless PET System Prototype.

Instrumentation research in small animal Positron Emission Tomography (PET) imaging is driven by improving timing, spatial resolution and sensitivity. Conventional PET scanners are built of multiple detectors placed in a cylindrical geometry with gaps between them in both the transaxial and axial planes. These gaps decrease sensitivity and degrade spatial resolution towards the edges of the system field of view (FOV).

Intra-articular platelet-rich plasma vs corticosteroids in the treatment of moderate knee osteoarthritis: a single-center prospective randomized controlled study with a 1-year follow up.

Background: Osteoarthritis is the most prevalent type of arthritis, which significantly impacts the patient's mobility and quality of life. Pharmacological treatments for osteoarthritis, such as corticosteroids, produce an immediate reduction of the patient's pain as well as an improvement in the patient's mobility and quality of life, but with a limited long-term efficacy. In this context, platelet-rich plasma (PRP) infiltrations represent a therapeutic tool due to its trophic properties and its ability to control inflammatory processes, especially in musculoskeletal applications.

Pilot performance of a dedicated prostate PET suitable for diagnosis and biopsy guidance.

Background: Prostate cancer (PCa) represents one of the most common types of cancers facing the male population. Nowadays, to confirm PCa, systematic or multiparametric MRI-targeted transrectal or transperineal biopsies of the prostate are required. However, due to the lack of an accurate imaging technique capable to precisely locate cancerous cells in the prostate, ultrasound biopsies sample random parts of the prostate and, therefore, it is possible to miss regions where those cancerous cells are present.

Possible Role of Chitin-Like Proteins in the Etiology of Alzheimer's Disease.

Chitin is a β-linked straight chain carbohydrate matrix monopolymer prominent in invertebrates, from fungi to arthropods. Surprisingly, chitin is now documented in vertebrates, including humans, a component of vertebrate physiology that has been neglected until now. Chitin levels are elevated in Alzheimer's disease (AD) patients, not only in the central nervous system but also in the cerebrospinal fluid and plasma.

Consensus statement: osteoporosis prevention and treatment in Latin America-current structure and future directions.

Background: Osteoporosis is a common disorder affecting populations worldwide. In Latin America, an aging population combined with limited health care resources result in osteoporosis quickly becoming a condition of considerable magnitude with disproportionate morbidity and mortality.

Aim: To review the current state of prevention, diagnosis, and treatment of osteoporosis in Latin America and to develop strategies and recommendations that may be adopted in the region, an expert panel of clinicians and scientists was assembled to develop a consensus statement outlining future directions.

The Discriminatory Ability of the Fibromyalgia Rapid Screening Tool (FiRST): An International Study in Spain and Four Latin American Countries.

Objective: To assess the transcultural equivalency of the Spanish version of the Fibromyalgia Rapid Screening Tool (FiRST) and its discriminatory ability in different Latin American samples.

Design: Validation study.

Setting: Departments of Rheumatology in general hospitals and private centers; fibromyalgia unit in a university hospital.

Inhaled mannitol for non-cystic fibrosis bronchiectasis: a randomised, controlled trial.

Rationale: Bronchiectasis is characterised by excessive production of mucus and pulmonary exacerbations. Inhaled osmotic agents may enhance mucociliary clearance, but few long-term clinical trials have been conducted.

Objectives: To determine the impact of inhaled mannitol on exacerbation rates in patients with non-cystic fibrosis (CF) bronchiectasis.

The Spanish version of the Fibromyalgia Rapid Screening Tool: translation, validity and reliability.

Objective: Despite showing acceptable psychometric properties, the criterion validity of the original Fibromyalgia Rapid Screening Tool (FiRST) has been called into question for including insufficiently challenging comparison groups. Consequently our objective was to validate a Spanish version of the FiRST including pain disorders more analogous to fibromyalgia.

Methods: The FiRST was translated following international standards.

[Active infective endocarditis: 152 cases].

Active infective endocarditis (IE) is a disease of low incidence that has showed changes in presentation, diagnosis and treatment options during the past decades. Despite these advances, mortality remains very high. Our goal was to analyze the characteristics of patients with active IE and their relationship with in-hospital mortality over 16 years.

Recombinant tissue factor pathway inhibitor in severe community-acquired pneumonia: a randomized trial.

Rationale: Severe community-acquired pneumonia (sCAP) is a leading cause of death worldwide. Adjunctive therapies for sCAP are needed to further improve outcome. A systemic inhibitor of coagulation, tifacogin (recombinant human tissue factor pathway inhibitor) seemed to provide mortality benefit in the sCAP subgroup of a previous sepsis trial.

Left ventricular thrombus mimicking primary cardiac tumor in a patient with primary antiphospholipid syndrome and recurrent systemic embolism.

Primary antiphospholipid syndrome (APS) is a well-defined entity characterized by spontaneous and recurrent abortion, thrombocytopenia and recurrent vascular thromboses (arterial and venous). Left ventricular thrombus mimicking primary cardiac tumor with recurrent systemic embolism has not been previously reported. In this report we describe a 39 year-old man admitted to hospital presenting with left hemiparesis and a peripheral embolism.

Impaired myocardial function in hypertrophic cardiomyopathy.

Background: Tissue Doppler imaging (TDI) parameters of peak myocardial velocities (S', E', and A') has been employed to assess the regional left ventricular myocardial function. The global function index (GFI) derived from TDI has been recently employed to distinguish the different etiologies of left ventricular hypertrophy.

Objective: To analyze whether the GFI or individual TDI parameters of peak myocardial velocities (S', E', and A') allows detecting different degrees of regional myocardial dysfunction in the most frequent forms of hypertrophic cardiomyopathy (HCM).

Utility of the aVL lead in the electrocardiographic diagnosis of atrioventricular node re-entrant tachycardia.

Aims: Reciprocating atrioventricular tachycardia can be categorized into common slow-fast atrioventricular node re-entrant (AVNRT) and orthodromic atrioventricular reciprocating tachycardia (AVRT). The electrocardiogram (ECG) during tachycardia is useful in distinguishing these two mechanisms. The presence of a pseudo-R'-wave in lead V1 or pseudo-S-wave in the inferior leads has been widely used, although the value of an isolated aVL lead has not been evaluated yet.

Right and left atrial appendage function in patients with mitral stenosis and sinus rhythm.

Tissue Doppler imaging (TDI) is generally used for the assessment of ventricular function, and to a lesser extent, to evaluate the left atrial appendage (LAA). In the present study, we used TDI to analyze the contractile function of the right atrial appendage (RAA). The aim of this study was a comprehensive evaluation of RAA and LAA contractile function in patients with mitral stenosis and sinus rhythm.

Left ventricular diverticulum, a rare echocardiographic finding: two adult patients and review of the literature.

Congenital diverticulum of the left ventricle is a very rare cardiac abnormality characterized by a local embryological development failure of the ventricular muscle. It may present as an isolated disorder or may be associated with other cardiac abnormalities. Clinically, it has been reported that it can lead to chest pain, arrhythmias, cardiac rupture, and sudden death, although frequently the course is asymptomatic.
