Upper limb movement quality measures: comparing IMUs and optical motion capture in stroke patients performing a drinking task. Front Digit Health 2024; 6:1359776. [PMID: 38606036 PMCID: PMC11006959 DOI: 10.3389/fdgth.2024.1359776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 03/13/2024] [Indexed: 04/13/2024] Open
Abstract
Introduction Clinical assessment of upper limb sensorimotor function post-stroke is often constrained by low sensitivity and limited information on movement quality. To address this gap, recent studies proposed a standardized instrumented drinking task, as a representative daily activity combining different components of functional arm use. Although kinematic movement quality measures for this task are well-established, and optical motion capture (OMC) has proven effective in their measurement, its clinical application remains limited. Inertial Measurement Units (IMUs) emerge as a promising low-cost and user-friendly alternative, yet their validity and clinical relevance compared to the gold standard OMC need investigation. Method In this study, we conducted a measurement system comparison between IMUs and OMC, analyzing 15 established movement quality measures in 15 mild and moderate stroke patients performing the drinking task, using five IMUs placed on each wrist, upper arm, and trunk. Results Our findings revealed strong agreement between the systems, with 12 out of 15 measures demonstrating clinical applicability, evidenced by Limits of Agreement (LoA) below the Minimum Clinically Important Differences (MCID) for each measure. Discussion These results are promising, suggesting the clinical applicability of IMUs in quantifying movement quality for mildly and moderately impaired stroke patients performing the drinking task.

Abstract
OBJECTIVE The aim of the present study was to investigate the effects of Grape seed extract (GSE) and exercise training on Doxorubicin (Doxo)-induced cardio, hepato and myo toxicities in healthy rats. METHODS Thirty male Wistar rats were randomly divided into five groups and daily treated by intraperitoneal route during two months either with ethanol 10% (Control); Doxo (1.5 mg/kg); Doxo + exercise (1.5 mg/kg + swimming exercise for 30 min twice a week); Doxo + GSE (1.5 mg/kg + GSE 2.5 g/kg); Doxo + GSE + exercise (1.5 mg/kg + GSE 2.5 g/kg + swimming exercise for 30 min twice a week). At the end of the treatment, tissues were collected and processed for the determination of oxidative stress (OS), intracellular mediators, energy fuelling biomarkers, carbohydrate metabolism parameters and muscle histopathology. RESULTS Doxo provoked OS characterised by an increased lipoperoxidation (LPO) and protein carbonylation and decreased antioxidant enzyme activities. Doxo also affected intracellular mediators, disturbed carbohydrate metabolism and energy fuelling in skeletal muscle as assessed by down-regulated Electron Transport Chain (ETC) complex activities leading in fine to altered skeletal muscle structure and function. CONCLUSION Almost all Doxo-induced disturbances were partially corrected with GSE and exercise on their own and more efficiently with the combined treatment (GSE + exercise).

Abstract
Background and purpose Multiple sclerosis (MS), a multifactorial autoimmune disease of the central nervous system (CNS), is characterized by demyelination and chronic inflammation, as well as axonal and neuronal loss. There is no cure for MS, and despite a significant improvement in the therapeutic management of patients during the last 20 years, some symptoms are still resistant to treatment, and the evolution of the disease to progressive form seems still ineluctable. The etiology of MS is complex and still not fully understood. However, inflammation is a major driver of physiopathology and oxidative stress contributes to CNS lesions and promotes existing inflammatory response. Plant polyphenols are endowed with many therapeutic benefits through alleviating oxidative stress and inflammation, thus providing neuroprotection in MS. We presently evaluated the curative effect of grape seed extract (GSE) in an experimental autoimmune encephalomyelitis (EAE) mouse model of MS. Experimental approach Six-week-old C57Bl/6J females were subjected to the EAE paradigm (using myelin oligodendrocyte glycoprotein peptide fragment (35-55), complete Freund’s adjuvant, and pertussis toxin) and then chronically treated with GSE from day 10 to day 30 post-induction. Clinical score and body weight were monitored daily, while evaluation of sensitive, motor, cognitive, and anxiety-related behaviors was performed weekly. Then, the GSE effect was evaluated on whole brain and spinal cord samples through the evaluation of oxidative stress damage, antioxidant capacities, myelin alteration, astroglial and microglial proliferation, and sirtuin expression. Key results Grape seed extract curative chronic treatment corrected the clinical course of EAE, as well as the mechanical hypersensitivity, and avoided the development of EAE mouse thermal cold allodynia. The neuropathological evaluation showed that GSE reduced oxidative stress in the brain and spinal cord by decreasing the lipid and protein oxidation through correction of the three main antioxidant enzyme activities, namely, superoxide dismutase, catalase, and glutathione peroxidase, as well as restoring normal myelin protein expression and correcting microglial and astroglial protein overexpression and sirtuin downregulation. Conclusion and implications These data strongly support GSE as an effective therapeutic approach in MS treatment.

Abstract
BackgroundEnthesopathy is one of the major features of psoriatic arthritis (PsA). The clinical screening for enthesopathies and synovitis in patients with psoriasis is nonspecific during the subclinical phase. Ultrasonography (US) has already demonstrated its ability to study entheses and joints in early stages of PsA.ObjectivesTo evaluate the prevalence of ultrasonographic subclinical synovitis and enthesopathies in psoriasis patients with no clinical evidence of PsA compared with controls.MethodsA cross-sectional study conducted on 40 patients with psoriasis and 40 healthy sex- and age- matched controls. The Leeds Enthesitis Index (LEI) and Spondyloarthritis Research Consortium of Canada (SPARCC) were used to evaluate entheseal involvement. US examination of 18 joints (wrists, metacarpophalangeal, and proximal interphalangeal joints) was performed along with 22 entheseal sites (deep flexor of the fingers, lateral epincondyle, triceps, quadriceps, patellar and calcaneal tendons and plantar fascia). Inflammatory-score (thickening, hypoechogenocity, bursitis and Doppler signal) and damage-score (calcifications, enthesophytes and erosions) were calculated (0= absent, 1=present for each abnormality). A total-score was obtained by adding these two scores.ResultsThe mean age of psoriatic patients 51,90±15,90 [19 -76] and the sex ratio of males to females was 3:2. US synovitis were more frequent in psoriatic patients 7/1040 (0,68%) than in controls 3/1040 (0,29%) but this was not significant (p= 0,420). Patients with psoriasis had more US enthesopathies 37 (92,5%) comparing to controls 16 (40%) (p < 0,001). The total number of enthesopathies was higher in the psoriatic group 184/880 (20,90%) comparing to controls 42/880 (4,78%) (p < 0,001). Entheses with more US abnormalities in the psoriasis group comparing to controls were deep flexor tendons of the fingers entheses (p<0,001), distal patellar tendon entheses (p<0,001) and calcaneal tendon entheses (p<0,001). LEI and SPARCC scores were positively correlated to higher number of US enthesopathies (p=0,046, p=0,006). SPARCC was positively correlated to inflammatory-score and damage-score (p=0,009, p=0,024). The mean C-reactive protein level was higher in psoriatic arthritis 5,77±10,10 mg/L than in controls 2,15±3,26mg/L (p=0,037).ConclusionOur results confirm that US enthesopathies and synovitis are more frequent in patients with psoriasis comparing to healthy population. The US screening for subclinical enthesopathies should be the object of longitudinal investigations to define its value in predicting the clinical onset of PsA.Disclosure of InterestsNone declared

Abstract
Allium sativum (As), commonly known as garlic, has been used for a long time, for its therapeutic effects. Recent studies showed the ability of As to modulate vascular activity. The present study aimed to investigate the vasomodulatory effects of aqueous extract of As and to analyse the molecular nature of the active components. Experiments were performed on chick chorioallantoic membrane. Fractions of garlic were directly injected using micropipette on a high vessel density area. Our results clearly indicated that garlic increased permeability and induced vasodilatation of blood vessels and capillaries. These effects were dose-dependent and had been observed just few minutes after the onset of treatment. The active component responsible of these effects, which had a low molecular weight seems to be of peptide nature and appeared different from Dially Sulfide (DAS) and Dially Disulfide (DADS).

Abstract
Ischemic stroke is a major health concern and a leading cause of mortality worldwide. Oxidative stress is an early event in the course of stroke inducing neuro-inflammation and cell death. Grape seed extract (GSE) is a natural phytochemical mixture exhibiting antioxidant, anti-inflammatory and neuroprotective properties. Orlistat (ORL) is an anti-obesity agent and a gastro-intestinal lipase inhibitor which showed recently beneficial effects on brain lipotoxicity. Recent studies reported the increase of lipase activity upon stroke which led us to investigate the neuroprotective effect of ORL on rat brain I/R injury as well as the putative synergism with GSE. I/R insult infarcted the brain parenchyma as assessed by TTC staining, induced an oxidative stress as revealed by increased lipoperoxidation along with alteration of antioxidant enzymes activities which was corrected using the cotreatment of ORL + GSE. I/R also disturbed the main metabolic pathways involved in brain fueling as glycolysis, neoglucogenesis, glycogenolysis, TCA cycle and electron transfer chain (ETC) complexes. These disturbances were also corrected with the cotreatment ORL + GSE which maintained energetic activities near to the control level. I/R also disrupted transition metals distribution, along with associated enzymes as tyrosinase, LDH or glutamine synthetase activities and induced hippocampal inflammation as revealed by glycogen depletion from dentate gyrus area along with depressed anti-inflammatory IL1β cytokine and increased pro-inflammatory CD68 antigen. Interestingly almost all I/R-induced disturbances were corrected either partially upon ORL and GSE on their own and the best neuroprotection was obtained in the presence of both drugs (ORL + GSE) enabling robust neuroprotection of the sub granular zone within hippocampal dentate gyrus area.

Abstract
Aluminum (Al) is recognized potent neurotoxic metal, which causes oxidative stress leading to intracellular accumulation of reactive oxygen species (ROS) and neuronal cell death in various neurodegenerative diseases. Among several medicinal plants with beneficial effects on health, curcumin acts as a multi-functional drug with antioxidant activity. Thus, the purpose of the present study was to evaluate the protective effect of curcumin against aluminum induced-oxidative stress and astrocytes death, in vitro ad in vivo. Incubation of cultured rat astrocytes with two concentrations of Al (37 μM and 150 μM) for 1 h provoked a dose-dependent reduction of the number of living cells as evaluated by Fluorescein diacetate and lactate dehydrogenase assay. Al-treated cells exhibited a reduction of both superoxide dismutase (SOD) and catalase activities. Pretreatment of astrocytes with curcumin (81 μM) prevented Al-induced cell death. Regarding in vivo study, rats were exposed acutely during three consecutive days to three different doses of Al (25 mg/kg, 50 mg/kg and 100 mg/kg, i.p injection), together with curcumin treatment (30 mg/kg). For the chronic model, animals were exposed to Al (3 g/l) in drinking water from intrauterine age to 4 months ages, plus curcumin treatment (175 mg/kg). Data showed that both acute and chronic Al intoxication induced an obvious astrogliosis within motor cortex and hippocampus, while, such effects were restored by curcumin. We showed herein that Al was highly toxic, induced astrocytes death. Then, curcumin protected astrocytes against Al-toxicity. The cytoprotective potential of curcumin is initiated by stimulation of endogenous antioxidant system.

Abstract
The pulmonary alveolocapillary dysplasia (ACD) with pulmonary vein misalignment (PVM) is a rare condition characterized by a congenital anomaly of the development of the pulmonary parenchyma. We present a case of an 8-month-old infant who died quickly from acute respiratory failure complicating an unknown ACD. We also describe its epidemiological characteristics in infants and we discuss the diagnosis's difficulties. In this case, a pulmonary arterial hypertension was decompensated by an infection. A medico-legal autopsy was performed. As for the Histological examination, it showed the features of ACD/PVM.

Ischemic stroke is a leading cause of mortality worldwide that occurs following the reduction or interruption of blood brain supply, characterized by a cascade of early events as oxidative stress and ensuing neuro-inflammation, energy failure and the burst of intracellular Ca++ resulting in activation of phospholipases and large increase in FFA including arachidonic acid, ultimately leading to nervous cell death. Grape Seed Flour (GSF) is a complex polyphenolic mixture harboring antioxidant, anti-inflammatory and neuroprotective properties. Orlistat (Xenical ™,Xe) is a gastro-intestinal lipase inhibitor and an anti-obesity agent. In an earlier study we reported the higher efficiency in neuroprotection against HFD-induced brain lipotoxicity when combining the two drugs (GSF + Xe). As a result repurposing Xe as an adjunct to GSF therapy against stroke appeared relevant and worthy of investigation. I/R insult disrupted the blood brain barrier (BBB) as assessed by EB dye extravasation, increased water and Na+ within the brain. Ultrastructurally I/R altered the brain blood capillaries at the vicinity of hippocampus dentate gyrus area as assessed by transmission and scanning electron microscopy. I/R altered lipid metabolism as revealed by LDL/HDL ratio, lipase activity, and FFA profiles. Moreover, I/R induced neuro-inflammation as assessed by down-regulation of anti-inflammatory CD 56 and up-regulation of pro-inflammatory CD 68 antigen. Importantly almost all I/R-induced disturbances were retrieved partially upon Xe or GSF on their own, and optimally when combining the two drugs. Xe per se is protective against I/R injury and the best neuroprotection was obtained when associating low dosage Xe with high dosage GSF, enabling neuroprevention and cell survival within hippocampus dentate gyrus area as revealed by increased staining of Ki 67 proliferation biomarker.

Preventive and curative effects of grape seed powder on stroke using in vitro and in vivo models of cerebral ischemia/reperfusion. Biomed Pharmacother 2020; 125:109990.

Abstract
Stroke is a worldwide concern. Many studies pointed out relevant preventive effect of grape seed powder (GSP) against deleterious brain ischemia/reperfusion (I/R) injury, but curative effect has been scarcely approached. The present work aimed at studying the preventive and curative effect of GSP against stroke using in-vitro and in-vivo models. Primary neuron-astrocyte cocultures were used to evaluate in-vitro GSP protective and curative effect on oxygen-glucose-deprivation (OGD). A murine I/R model, in which GSP was administered as delayed post stroke drug, to evaluate its potential clinically translatable therapy was used and behavioral tests were conducted after 15 days. Ultra-structure of hippocampus dentate gyrus using Transmission Electron Microscopy (TEM) was also undertaken. GSP prevented OGD-induced toxicity and cell death in a dose dependent manner and was neuroprotective as assessed by sustained cell viability (70 % ±1 for OGD + GSP and 37 % ±2 for OGD) and modulated cytokines and brain derived neurotrophic factor (BDNF) expression. GSP also promoted behavioral outcomes by increasing step-down inhibitory time from 17s±4 to 50s±11 and rat overall activities by improving scores in open field test to near control level. Furthermore, GSP protected hippocampus dentate gyrus area from I/R-induced drastic alterations as assessed by reduced autophagic vacuoles.

Abstract
INTRODUCTION Pyoderma gangrenosum (PG) is a neutrophilic dermatosis that is traditionally associated with systemic disorders such as chronic inflammatory bowel diseases, rheumatoid arthritis and malignant hematologic disorders. Its association with systemic lupus erythematosus (SLE) is rare and not well known. We report a case of this association with a review of the literature. CASE REPORT A 43-year-old female patient, followed for 4 years for SLE, presented a deep ulceration of the anterior face of the left thigh with inflammatory borders, an ulcerated nodule of the right shoulder and four small ulcerations of the back of the right hand. The biopsy of the ulceration of the left thigh concluded to PG. The patient was treated by corticosteroids with complete healing of lesions. CONCLUSION The prognosis of lupus does not seem to be aggravated by PG and the treatments of a SLE flare are usually enough for treating associated PG.
