Integrating Clinical Expertise in the Design of Home-Based Smart Rehabilitation Devices for Motor and Cognitive Therapy in Patients with Neurological Disorders
No full textHome-based motor and cognitive rehabilitation are critical for fostering autonomy and reducing long-term healthcare dependency among patients with neurological impairments. Although existing commercial and research-based devices like smart walkers and other mobility aids cater to some patient needs, their design predominantly reflects technical, rather than clinical perspectives, resulting in limited alignment with the specific functional needs of patients with complex neurological deficits. This study aims to bridge this gap by directly involving the domain experts in the definition of the features and functionalities of assistive smart devices tailored to motor assistance and rehabilitation in home environments. Central to this approach is the integration of insights from clinical experts, including physicians, psychologists, physical therapists, and occupational therapists, who bring a nuanced understanding of patient needs within daily life contexts. The main qualitative features that a smart bed and smart walker, integrated into a home-based system for assistance and rehabilitation, should incorporate have been identified through collaborative brainstorming sessions with the experts. These results set up a starting point for these devices’ development
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Rare combination of left ventricular noncompaction, bicuspid aortic valve and myocardial bridging. Rare case or common genetic mutations?
Full text linkDispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Triple oral combination therapy in patients with idiopathic pulmonary arterial hypertension and recurrent vessel dissection of inoperable pulmonary artery aneurysm
No full textBackground: Pulmonary artery aneurysm is a rare condition related to the stress that the vascular wall undergoes with progressive dilation. A clear definition and its prevalence are not available. Pulmonary arterial hypertension is also a life-threatening and progressive condition which requires specific therapies. Case report: We describe the case of a 62-year-old Caucasian woman with idiopathic pulmonary arterial hypertension and inoperable giant pulmonary artery aneurysm associated with recurrent vessel dissection. Diagnosis was simple with the use of echocardiography and computed tomography. Conversely, deciding on the treatment was difficult, because surgeons declined to perform surgical repair of the aneurysm. We treated the patient medically with specific drugs for pulmonary arterial hypertension assuming to reduce the load pressure on the vascular wall of the pulmonary artery. Discussion: We describe a very rare and extremely serious condition characterized by the concomitant presence of pulmonary arterial hypertension appropriately treated with effective triple oral combination therapy and inoperable pulmonary artery aneurysm with recurrent dissection
Treatment failure of low molecular weight heparin bridging therapy in atrial fibrillation after acute coronary syndrome.
No full textThrombosis prevention in atrial fibrillation is a very common
problemfor cardiologists. Lowmolecularweight heparin bridging therapy
(LMWH-BT) has been considered in patients at high risk of thromboembolism
during the start or temporary interruption of oral anticoagulation
therapy]. Several cases of treatment failure of LMWH-BT have
been reported]. A 70-year-old man, with a history of arterial
hypertension, recurrent atrial fibrillation andmild aortic valve stenosis in
oral anticoagulant therapy , came to our observation for inferior
STEMI complicated by total BAV. In urgencywas inserted
PM temporary and revascularized with double DES for thrombotic
occlusion of the proximal right coronary artery. The current therapy with
LMWH was standardized according to body weight, beta-blockers, ACE
inhibitors, diuretics, aspirin and clopidogrel [34–36]. After 3 days the ECG
showed atrial fibrillation. After 6 days the patient has sudden
expressive aphasia and hemi-facial-brachial left. Echocardiographic
assessment did not detect the presence of thrombus in the cardiac
chambers. A computed tomography performed in emergency and
after 24 h showed cerebral ischemic injury. Also this case focuses
on the failure of treatment with LMWH-BT.
