Mobile applications to prescribe physical exercise in frail older adults: review of the available tools in app stores.

Introduction: Different remote interventions, such as applications (apps), have been used to continue promoting healthy ageing and preventing disability during the COVID-19 pandemic. The growing trend of apps in health is exponential and may facilitate scaling up physical activity prescription. Numerous tools are available, but little is known regarding their appropriateness, validation and recommendation, especially for frail older adults.

A new FRAX model for Brazil.

Unlabelled: Fracture probabilities derived from the original FRAX model for Brazil were compared to those from an updated model based on more recent regional estimates of the incidence of hip fracture. Fracture probabilities were consistently lower in the updated FRAX model. Despite large differences between models, differences in the rank order of fracture probabilities were minimal.

An updated hip fracture incidence rate for Brazil: the Brazilian Validation Osteoporosis Study (BRAVOS).

Unlabelled: Hip fracture incidence rates in three representative geographic areas in Brazil over a period of 2 years (2010-2012) were assessed for the first time. Estimated incidence rates varied regionally, and markedly differed from those previously reported. Thus, national guidelines as well as FRAX Brazil should be revised in light of this new data.

Mobile Applications in Mood Disorders and Mental Health: Systematic Search in Apple App Store and Google Play Store and Review of the Literature.

Objectives: The main objective of this work was to explore and characterize the current landscape of mobile applications available to treat mood disorders such as depression, bipolar disorder, and dysthymia.

Methods: We developed a tool that makes both the Apple App Store and the Google Play Store searchable using keywords and that facilitates the extraction of basic app information of the search results. All app results were filtered using various inclusion and exclusion criteria.

[Acceptance of video consultation among patients with inflammatory rheumatic diseases depends on gender and location-Results of an online survey among patients and physicians].

Introduction: In order to successfully integrate telemedicine into the daily routine of rheumatology, both the patient's and the physician's perspective are important. For this purpose, a detailed study by means of a web-based survey was conducted by the Working Group Young Rheumatology (AGJR) of the German Society for Rheumatology (DGRh) and the German Rheumatism League National Association. By means of subgroup analysis of the data regarding video consultation, the aim was now to find out which requirements and wishes patients and physicians have for video consultations.

Digital rheumatology in the era of COVID-19: results of a national patient and physician survey.

Objective: To analyse the impact of the COVID-19 pandemic on rheumatic patients' and rheumatologists' usage, preferences and perception of digital health applications (DHAs).

Methods: A web-based national survey was developed by the Working Group Young Rheumatology of the German Society for Rheumatology and the German League against Rheumatism. The prospective survey was distributed via social media (Twitter, Instagram and Facebook), QR code and email.

Development and validation of bioengineered intestinal tubules for translational research aimed at safety and efficacy testing of drugs and nutrients.

Currently used intestinal cell models have limited translational value, therefore, development of novel in vitro intestinal models that recapitulate the human in vivo setting more closely are of interest. Here, an advanced intestinal model was developed by the incorporation of physiological parameters, such as extracellular matrix (ECM) elements and shear stress, to cultured Caco-2 cells in a 3-dimensional environment. Caco-2 cells grown on ECM-coated hollow fiber membranes (HFM) under physiological shear stress show an improved phenotype, as demonstrated by the presence of enterocytes, goblet, Paneth, enteroendocrine and stem cells.

Incidence and excess mortality of hip fractures in a predominantly Caucasian population in the South of Brazil.

Introduction: Osteoporosis is a very common disease, and data on its epidemiology is important for health care strategy implementation. Brazil is a developing country; its population is aging, leading to an expected increase in hip fractures and their undesirable consequences.

Objective: Assess the incidence of osteoporotic hip fractures and subsequent mortality in Southern Brazil as part of a large epidemiological study aiming to reinforce the data for FRAX Brazil.

Vitamin K Supplementation Modulates Bone Metabolism and Ultra-Structure of Ovariectomized Mice.

Background/aims: Osteoporosis is a bone metabolic disease that affects mostly post-menopausal women. There has been shown that vitamin K (VK) supplementation during menopause may decrease bone loss as well as risk of bone breaking. Aiming to clarify the beneficial role of VK in bone metabolism during menopause, we investigated mineral metabolism and bone ultrastructure of ovariectomized (OVX) mice.

Role of APOE Gene in Bone Mineral Density and Incidence of Bone Fractures in Brazilian Postmenopausal Women.

Osteoporosis is one of the major diseases that affects mostly postmenopausal women. Despite being a multifactorial disease, some genes have been shown to play an important role in osteoporosis. Bone mineral density (BMD) is still largely used to diagnose it, although many other biomarkers are used to better follow the disease onset.

Spontaneous supracondylar femoral fracture in an HIV patient in lotus position.

Bone disorders have been described in patients chronically infected with human immunodeficiency virus (HIV). A case of spontaneous supracondylar femoral fracture that occurred in a 58-year-old monk during meditation is reported. His AIDS disease was controlled with combination antiretroviral therapy.

Epidemiology of osteoporotic fractures in Brazil: what we have and what we need.

The epidemiology of osteoporotic fractures varies widely among countries and is primarily related to differences in the population and utilization of public healthcare services. Since 1994, over 200 studies about osteoporosis and fractures have been conducted in Brazil, among which 60 have described the current epidemiological status. This work is a compilation of studies published in scientific journals (PubMed, MedLine, Lilacs, SciELO Database) with the respective highlights.

[2008 official positions of the Brazilian Society for Clinical Densitometry--SBDens].

With the evolution of bone densitometry, differences in technologies, acquisition techniques, reference databases, reporting methods, diagnostic criteria and terminology have developed and the International Society for Clinical Densitometry (ISCD) periodically holds Position Development Conferences, the latest in 2007. The Brazilian Society for Clinical Densitometry (SBDens), with support from many Brazilian societies interested in bone health, gathered numerous specialists to discuss the ISCD proposals and to evaluate the validity of the extension of those norms to Brazilian population. The SBDens reunion of consensus made a very useful document to help the understanding and interpretation of bone densitometry and other methods of bone assessment.

Effects of short-term risedronate on bone resorption and patient satisfaction in postmenopausal osteoporosis patients.

This multicenter, open-label study evaluated the effects of short-term risedronate on bone resorption and patient satisfaction in postmenopausal women with osteoporosis in Brazil.

Dual-Energy X-Ray Absorptiometry Technical issues: the 2007 ISCD Official Positions.

At the 2007 Position Development Conference, the Dual-Energy X-ray Absorptiometry Technical Task Force investigated three major areas of bone density testing. Although bone mineral density (BMD) testing in men had previously been reviewed at the 2005 Position Development Conference, we reviewed the most recent data in men to develop appropriate indications for bone density testing in men. We continue to recommend screening at age 70 and discuss the clinical risk factors that may be an appropriate indication for earlier BMD testing.

Peripheral bone densitometry: Clinical applications.

Technologies for the measurement of bone mineral density and other parameters of bone strength at peripheral skeletal sites have been studied since the 1960s. Single-energy Photon Absorptiometry (SPA), Radiographic Absorptiometry (RA), Radiogrametry (RG), Single-energy X-ray Absorptiometry (SXA), Peripheral Dual-energy X-ray Absorptiometry (pDXA), and Quantitative Ultrasonometry (QUS) have been successively evaluated. These technologies and their clinical applications are discussed in this article.

Diagnosis and treatment of osteoporosis in Brazil.

The definition of Osteoporosis as proposed by WHO is widely accepted amongst Brazilian physicians. The main diagnostic tool in Brazil is Bone Densitometry (DXA). Both public and private health insurance systems reimburse the densitometry test.
