Abstract
Wearable sensing technologies are having a worldwide impact on the creation of novel business opportunities and application services that are benefiting the common citizen. By using these technologies, people have transformed the way they live, interact with each other and their surroundings, their daily routines, and how they monitor their health conditions. We review recent advances in the area of wearable sensing technologies, focusing on aspects such as sensor technologies, communication infrastructures, service infrastructures, security, and privacy. We also review the use of consumer wearables during the coronavirus disease 19 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and we discuss open challenges that must be addressed to further improve the efficacy of wearable sensing systems in the future.

Abstract
Anderson-Fabry disease is an X-linked lysosomal storage disorder caused by mutations in the GLA gene that result in deficiency of the enzyme alpha-galactosidase A. The worldwide incidence of Fabry's disease is reported to be in the range of 1 in 40,000-117,000, although this value may be a significant underestimate given under recognition of symptoms and delayed or missed diagnosis. Deficiency in alpha-galactosidase A causes an accumulation of neutral glycosphingolipids such as globotriaosylceramide (Gb3) in lysosomes within various tissues including the vascular endothelium, kidneys, heart, eyes, skin and nervous system. Gb3 accumulation induces pathology via the release of pro-inflammatory cytokines, growth-promoting factors and by oxidative stress, resulting in myocardial extracellular matrix remodelling, left ventricular hypertrophy (LVH), vascular dysfunction and interstitial fibrosis. Cardiac involvement manifesting as ventricular hypertrophy, systolic and diastolic dysfunction, valvular abnormalities and conduction tissue disease is common in AFD and is associated with considerable cardiovascular morbidity and mortality from heart failure, sudden cardiac death and stroke-related death.

Abstract
Anderson-Fabry disease (AFD) is a lysosomal storage disease caused by the inappropriate accumulation of globotriaosylceramide in tissues due to a deficiency in the enzyme α-galactosidase A (α-Gal A). Anderson-Fabry cardiomyopathy is characterized by structural, valvular, vascular and conduction abnormalities, and is now the most common cause of mortality in patients with AFD. Large-scale metabolic and genetic screening studies have revealed AFD to be prevalent in populations of diverse ethnic origins, and the variant form of AFD represents an unrecognized health burden. Anderson-Fabry disease is an X-linked disorder, and genetic testing is critical for the diagnosis of AFD in women. Echocardiography with strain imaging and cardiac magnetic resonance imaging using late enhancement and T1 mapping are important imaging tools. The current therapy for AFD is enzyme replacement therapy (ERT), which can reverse or prevent AFD progression, while gene therapy and the use of molecular chaperones represent promising novel therapies for AFD. Anderson-Fabry cardiomyopathy is an important and potentially reversible cause of heart failure that involves LVH, increased susceptibility to arrhythmias and valvular regurgitation. Genetic testing and cardiac MRI are important diagnostic tools, and AFD cardiomyopathy is treatable if ERT is introduced early.

Abstract
Cardiac manifestations of Anderson-Fabry disease are usually part of a multiorgan involvement; they are frequently recognized in the young adult and increase morbidity and mortality. Cardiac complications, first hypertension and diastolic dysfunction, are observed in about half of patients and are accessible to the usual management of hypertension, heart failure, coronary artery disease, rhythm or conduction disturbances. However, the cardiac variant may present as an isolated or predominant cardiac involvement, with left ventricular hypertrophy being the most apparent sign, that could lead to the wrong diagnosis of « idiopathic » hypertrophic cardiomyopathy of sarcomeric origin (in 1-4% of cases, up to 6% in males before 40 years). However, in Fabry disease, hypertrophy is more often concentric without subaortic obstruction, while search for signs of Fabry disease (history of acroparesthesia or anhidrosis, renal dysfunction or stroke) should be systematic. Early identification of subjects with Fabry disease allows to check for target organ damage, family screening, genetic counseling and specific enzyme replacement therapy. The latter, in the absence of irreversible and extended myocardial fibrosis and/or severe renal dysfunction, is efficient on the progression of renal disease and cardiac hypertrophy and delayed in parallel the occurrence of a first renal, cardiac or neurologic event.

Abstract
Fabry disease is an X-linked lysosomal storage disorder due to deficiency of the enzyme alpha-galactosidase A. The principal clinical manifestations of Fabry disease consist of cardiovascular complications including cerebrovascular, renal and cardiac disease but the pathophysiology of this specific vasculopathy is unclear. With the development of targeted treatment for Fabry disease, i.e. enzyme replacement therapy, it has become apparent that the removal of stored glycosphingolipid from the endothelial cells does not prevent progression of vascular disease in many patients. The aim of this study is to review the current available literature on vascular function tests, imaging and pathology studies and propose a hypothesis on the evolution of arterial complications in Fabry disease. Clearly, although premature atherosclerosis is suggested to occur, most studies describe absence of characteristic plaque formation. Smooth muscle cell hypertrophy, is probably the earliest feature of a complex vasculopathy, as in females and atypical cardiac variants, who have residual enzyme activity, no endothelial storage of significance is found. Subsequently, processes occur as observed in neo intima formation however with formation of more fibrotic structures. In the presence of a hyperdynamic circulation in combination with a less compliant vascular wall, it is hypothesized that upregulation of local renin angiotensine systems may occur. Angiotensin II is known to increase adhesion molecules, cytokines and chemokines and exerts a pro-inflammatory effect on leucocytes, endothelial cells and vascular smooth muscle cells. This enhances release of pro-thrombotic factors and opposes actions mediated through angiotensin 2 (AT2) receptor, including the release of nitric oxide (NO). A combination of reduced vascular compliance and activation of pro-thrombotic factors can lead to vascular complications in Fabry disease.

Abstract
Fabry Disease is an X-linked lysosomal storage disorder leading to the accumulation of glycosphingolipids, mainly globotriaosylceramides in all tissues and solid organs of the body. The disease was described by Johannes Fabry and William Anderson coevally in 1898. Beside the involvement of the central nervous system, peripheral nerves, kidneys, skin and endovascular endothelium, the heart plays a major role in the disease. Left ventricular hypertrophy is one hallmark initially presenting with preserved ventricular function. However, with progression of the disease patients die due to heart failure. Though angina is often reported, the incidence of epicardial coronary stenosis is not a dominant feature, if at all small vessel disease can occur. In respect of arrhythmias a broad spectrum can be seen including shortened or prolonged PR-intervals, AV blocks of different degrees and sometimes malignant ventricular arrhythmias. In the past, women were considered to be carriers of the disease but hardly to develop clinical symptoms. In recent years there is evidence that female carriers may more often be affected with severe symptoms. In addition, a group of Fabry patients displaying mainly cardiac involvement were described as having a cardiac variant of the disease. This implied the hypothesis that some of those patients with unexplained myocardial hypertrophy do suffer from Fabry disease. Since 2002 enzyme replacement therapy is available and there is first evidence for its efficacy to reduce hypertrophy and increase myocardial function. If this is associated with a prognostic improvement has to be determined in future studies.

Abstract
UNLABELLED Fabry disease is a rare X-linked defect of the lysosomal enzyme alpha-galactosidase A. The disease is characterized by progressive intracellular accumulation of neutral glycosphingolipids. The storage occurs within various tissues and cells, including cardiocytes, the cardiac conduction system, and valvular fibrocytes. Cardiac involvement may be the sole manifestation of the disease, particularly in individuals with residual enzyme activity. In general, hemizygous men are more seriously affected than heterozygous women. The main cardiac manifestations include myocardial hypertrophy, which, in some patients, mimics hypertrophic cardiomyopathy. Conduction system involvement leads to PR shortening or, in later stages, to AV blocks. Arrhythmias presenting with variable severity also appear to be common. Valvular involvement is frequently noted but generally mild and clinically non-significant. Newly available enzyme replacement therapy has produced promising results in preventing further functional deterioration of affected organs and possibly also in reversing impaired function. CONCLUSIONS With the advent of effective enzyme replacement therapy, early diagnosis of Fabry disease may be crucial for patient prognosis.

Abstract
Fabry disease is an X-linked lysosomal storage disorder that results from a deficiency of the enzyme alpha-galactosidase A (alpha-Gal A). The lack of alpha-Gal A causes an intracellular accumulation of glycosphingolipids, mainly globotriaosyceramide (GL3). Affected organs include, among others, the vascular endothelium, heart, brain, and kidneys, leading to end-stage renal disease (ESRD). Since Fabry disease cannot be cured at present, clinical management is symptomatic. Enzyme replacement therapy (ERT) with recombinant alpha-Gal A has been introduced as a new therapeutic option for the treatment of Fabry patients. Short-term (one year) clinical studies have positively correlated ERT with improvement of clinical symptoms and microvascular endothelial cell clearance. Treatment outcome concerning severe organ manifestations such as proteinuria and renal function impairment, left ventricular hypertrophy, and heart failure in the long run has yet to be shown. In our studies we used sensitive and noninvasive techniques such as ultrasound-based strain rate imaging and magnetic resonance imaging (MRI), combined with MR-spectroscopy (MR-S), for the quantification of functional abnormalities at an early stage of the disease and during long-term follow-up. Future issues should determine the appropriate timing to start therapy and how children and heterozygous females should be managed. Given the diagnostic and therapeutic potential today, it is of importance to identify patients at an early stage and to start therapeutic intervention before progression of organ damage is inevitable.
