Incidence and Predictors of Cerebrovascular Accidents in Patients Undergoing Transcatheter Mitral Valve Repair with Mitraclip.

BACKGROUND: Transcatheter mitral edge-to-edge repair (TEER) with transcatheter devices has become a mainstay in the minimally invasive treatment of patients with severe mitral regurgitation at increased surgical risk. Despite its apparently favorable risk profile, there is uncertainty on the risk and features of cerebrovascular accidents (CVA) early and long after TMVR. We aimed at appraising incidence and predictors of CVA in patients undergoing TEER. METHODS: We explicitly queried the dataset of an ongoing multicenter prospective observational study dedicated to TEER with MitraClip (Abbott Vascular, Santa Clara, CA, USA). Incidence of CVA after TEER was formally appraised, and we explored also potential predictors of such event. Descriptive, bivariate and diagnostic accuracy analyses were performed. RESULTS: Out of 2238 patients undergoing TEER, CVA occurred in 33 (1.47% [95% confidence interval 1.02% to 2.06%]), including 6 (0.27% [0.10% to 0.58%]) inhospital strokes and 27 events after discharge (0.99% [0.66% to 1.44%]) over a median follow-up of of 14 months. Most CVA were major ischemic strokes, during the inhospital phase as well as subsequently. Overall, CVA were more common in patients with atrial fibrillation (p=0.018), renal dysfunction (p=0.032), higher EuroSCORE II (p=0.033), and, as expected, higher CHA2DS2-VASc score (p=0.033), despite the limited prognostic accuracy of such score. Notably, the occurrence of CVA did not confer a significantly increased risk of long-term death (p=0.136) or cardiac death (p=0.397). CONCLUSIONS: The incidence of CVA in patients undergoing TEER is low, with most events occurring after discharge, and being associated with pre-existing risk features. These findings, while reassuring on the safety of TEER, call for proactive antithrombotic therapy whenever CVA risk is increased before, as well as after such intervention.

Genetic polymorphisms and post-stroke upper limb motor improvement - A systematic review and meta-analysis.

Background: Post-stroke upper limb (UL) motor improvement is associated with adaptive neuroplasticity and motor learning. Both intervention-related (including provision of intensive, variable, and task-specific practice) and individual-specific factors (including the presence of genetic polymorphisms) influence improvement. In individuals with stroke, most commonly, polymorphisms are found in Brain Derived Neurotrophic Factor (BDNF), Apolipoprotein (APOE) and Catechol-O-Methyltransferase (COMT). These involve a replacement of cystine by arginine (APOEε4) or valines by 1 or 2 methionines (BDNF:val66met, met66met; COMT:val158met; met158met). However, the implications of these polymorphisms on post-stroke UL motor improvement specifically have not yet been elucidated. Objective: Examine the influence of genetic polymorphism on post-stroke UL motor improvement. Design: Systematic Review and Meta-Analysis. Methods: We conducted a systematic search of the literature published in English language. The modified Downs and Black checklist helped assess study quality. We compared change in UL motor impairment and activity scores between individuals with and without the polymorphisms. Meta-analyses helped assess change in motor impairment (Fugl Meyer Assessment) scores based upon a minimum of 2 studies/time point. Effect sizes (ES) were quantified based upon the Rehabilitation Treatment Specification System as follows: small (0.08-0.18), medium (0.19 -0.40) and large (≥0.41). Results: We retrieved 10 (4 good and 6 fair quality) studies. Compared to those with BDNF val66met and met66met polymorphism, meta-analyses revealed lower motor impairment (large ES) in those without the polymorphism at intervention completion (0.5, 95% CI: 0.11-0.88) and at retention (0.58, 95% CI:0.06-1.11). The presence of CoMT val158met or met158met polymorphism had similar results, with lower impairment (large ES ≥1.5) and higher activity scores (large ES ranging from 0.5-0.76) in those without the polymorphism. Presence of APOEε4 form did not influence UL motor improvement. Conclusion: Polymorphisms with the presence of 1 or 2 met alleles in BDNF and COMT negatively influence UL motor improvement.

This research paper focuses on the impact of variations in DNA sequence in certain genes on improvement seen in the arms in people who have had a stroke. In this study, we studied the role of 3 genes previously identified as having variations in DNA sequence. The authors searched published research articles from 2000 onwards and selected articles that satisfied certain criteria. We then checked the quality of the selected papers. Next, we combined common data from same tests used to examine motor improvement in the arms to check if there was an overall effect. A total of 10 papers were found. The selected articles were either good or moderate in quality. Variations in DNA structure in 2 out of the 3 genes studied affected the ability to improve the use of the arms in daily life after a stroke. Such information can have important implications in the extent of recovery that is possible after a stroke. It can also be helpful to decide the best rehabilitation options that can be offered to help maximize their ability to use the arms after a stroke.

Risk of stroke development following retinal vein occlusion: A systematic review and meta-analysis.

Retinal vein occlusion (RVO) and cerebrovascular disease share common risk factors and may be independently associated; however, the strength and nature of this association remain unclear. We conducted a systematic review and meta-analysis, informed by studies from PubMed, Scopus, EMBASE, Web of Science, and Google Scholar until January 6, 2024, aimed to clarify this relationship. Eligible studies included cohorts observing stroke incidence in RVO patients for over a year. Pooled effect estimates were calculated using random-effects models, with subgroup analyses evaluating associations between RVO types (central and branch) and stroke subtypes (ischemic and hemorrhagic). Ten cohort studies with a total of 428,650 participants (86,299 RVO patients) were included. Compared to controls, RVO patients exhibited a significantly increased risk of stroke (pooled risk ratio [RR]=1.38, 95 % confidence interval (95 %CI)=1.34-1.41). Subgroup analyses indicated elevated risk for both ischemic (RR=1.37, 95 %CI=1.32-1.42) and hemorrhagic (RR=1.55, 95 %CI=1.08-2.22) strokes in RVO patients. Additionally, both central (RR=1.50, 95 %CI=1.27-1.78) and branch (RR=1.41, 95 %CI=1.32-1.50) RVO were associated with stroke risk. Sensitivity analyses confirmed consistent results across various criteria, and funnel plots indicated no publication bias. RVO significantly increases the risk of both ischemic and hemorrhagic stroke, regardless of RVO type, suggesting a strong independent association between these conditions.

Preoperative Nonselective Chest Computed Tomography Prior to Primary Cardiac Surgery Results in Meaningful Change to Surgical Management: Systematic Review and Pooled Prevalence Meta-Analysis.

BACKGROUND: Routine screening chest computed tomography (CT) prior to primary cardiac surgery is advocated by some surgeons due to the purported benefits of identifying significant aortic calcification that impacts ongoing management, such as performing anaortic off-pump surgery or adjusting cannulation strategy. Additionally, axial imaging can identify incidental findings that may require concomitant or staged procedures such as ascending aortic dilatation or pulmonary lesions. The objective of this study was to quantify the impact that nonselective chest CT prior to primary cardiac surgery had on subsequent management. METHOD: A systematic review and pooled prevalence meta-analyses were performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Included studies performed non-selective chest CT prior to primary cardiac surgery. RESULTS: A total of eight studies, including 2,250 patients were included. The rate of mortality and stroke was low (1% and 2%, respectively). Calcification of the ascending aorta was identified in 15% of patients (95% confidence interval [CI] 5.0-26.0). A significant change to the surgical plan such as cannulation strategy, off-pump surgery, cancellation, or an additional procedure was required in 7% (95% CI 2.0-12.0). Clinically relevant incidental findings requiring in-patient management or follow-up were identified in 10% (95% CI 6.0-14.0). CONCLUSIONS: Nonselective CT chest prior to primary cardiac surgery identifies clinically relevant findings that result in a modification of the surgical plan in a significant population of patients to address the risk of stroke associated with aortic calcification as well as the identification of important incidental findings such as pulmonary lesions.

Off-pump Versus On-pump Coronary Artery Bypass Grafting in Diabetic patients: A Meta-analysis of Observational Studies with a Propensity-Score Analysis.

PURPOSE: The debate between off-pump coronary artery bypass grafting (OPCAB) and on-pump coronary artery bypass grafting (ONCAB) in diabetic patients remains. This meta-analysis aimed to investigate outcomes after OPCAB versus ONCAB for patients with diabetes. METHODS: Literature research was conducted up to December 2023 using Ovid Medline, EMBASE, and the Cochrane Library. Eligible studies were observational studies with a propensity-score analysis of OPCAB versus ONCAB. The primary outcomes were early mortality and mid-term survival. The secondary outcomes were cerebrovascular accidents, reoperation for bleeding, incomplete revascularization, myocardial infarction, low cardiac output, and renal replacement therapy. RESULTS: Our research identified seven observational studies with a propensity-score analysis enrolling 13,085 patients. There was no significant difference between OPCAB and ONCAB for early mortality, mid-term survival, myocardial infarction, low cardiac output, and renal replacement therapy. OPCAB was associated with a lower risk of cerebrovascular accidents (OR 0.43; 95% CI, 0.24-0.76, P = 0.004) and reoperation for bleeding (OR 0.60; 95% CI, 0.41-0.88, P = 0.009). However, OPCAB was associated with a higher risk of incomplete revascularization (OR 2.07; 95% CI, 1.60-2.68, P < 0.00001). CONCLUSION: Among patients with diabetes, no difference in early mortality and mid-term survival was observed. However, OPCAB was associated with a lower incidence of morbidity, including cerebrovascular accidents and reoperation for bleeding.

Obstetric and perinatal outcomes in women with cerebrovascular accident vs. transient ischemic attack: an evaluation of a population database.

PURPOSE: Cerebrovascular accidents (CVAs) and transient ischemic attacks (TIAs) are uncommon neurologic events in women of childbearing age. We aimed to compare pregnancy, delivery, and neonatal outcomes between women who suffered from a CVA and those who experienced a TIA. METHODS: A retrospective population-based cohort study was performed using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample. Included were all pregnant women who delivered or had a maternal death in the US between 2004 and 2014. We compared women with an ICD-9 diagnosis of a CVA before or during pregnancy to those diagnosed with a TIA before, during the pregnancy, or during the delivery admission. Pregnancy and perinatal outcomes were compared between the two groups, using multivariate logistic regression to control for confounders. RESULTS: Among 9,096,788 women in the database, 898 met the inclusion criteria. Of them, 706 women (7.7/100,000) had a CVA diagnosis, and 192 (2.1/100,000) had a TIA diagnosis. Women with a CVA, compared to those with a TIA, had a higher rate of pregnancy-induced hypertension (aOR 3.82,95%CI 2.14-6.81, p < 0.001); preeclampsia (aOR 2.6,95%CI 1.3-5.2, p = 0.007), eclampsia (aOR 13.78,95% CI 1.84-103.41, p < 0.001); postpartum hemorrhage (aOR 4.52,95%CI 1.31-15.56, p = 0.017), blood transfusion (aOR 5.57,95%CI 1.65-18.72, p = 0.006), and maternal death (54 vs. 0 cases, 7.6% vs. 0%), with comparable neonatal outcomes. CONCLUSION: Women diagnosed with a CVA before or during pregnancy had a higher incidence of myriad maternal complications, including hypertensive disorders of pregnancy, postpartum hemorrhage, and death, compared to women with a TIA diagnosis, with comparable neonatal outcomes, stressing the different prognoses of these two conditions, and the importance of these patients' diligent follow-up and care.

Varicella Zoster Virus Vasculopathy: An Under-Recognized Entity.

Varicella zoster virus (VZV) vasculopathy is a rare yet potentially severe neurological manifestation resulting from VZV reactivation, primarily affecting immunocompromised individuals. We present a case report of a 61-year-old male with VZV vasculopathy who initially presented with herpes zoster ophthalmicus, subsequently complicated by meningoencephalitis and an acute infarct in the territory of the left middle cerebral artery (MCA). Imaging revealed acute and chronic infarcts in the capsuloganglionic regions, accompanied by thickening and enhancement of the left MCA wall. Treatment involved a 14-day course of intravenous acyclovir, supplemented with oral prednisolone, resulting in modest clinical improvement. VZV vasculopathy represents an infrequently acknowledged neurological syndrome, particularly prevalent among immunocompromised individuals. Early recognition and appropriate intervention offer promise in ameliorating outcomes for affected patients. This case emphasizes the importance of including VZV vasculopathy in the differential diagnosis of neurological deficits, especially within high-risk populations.

Responsiveness and construct validity of two outcome measures of bilateral upper limb function in patients with chronic stroke.

Background: Stroke is a leading cause of long-term disability among stroke survivors. Despite the availability of numerous stroke rehabilitative therapies, such as mirror therapy, bilateral arm training, and robot-assisted therapy, the recovery of motor function after stroke remains incomplete. Bilateral arm function is a key component in stroke patients to perform activities of daily living and to reflect their functional autonomy. Objective: This clinimetric study investigated and compared the construct validity and responsiveness of 2 bimanual activity outcome measures, the Chedoke Arm and Hand Activity Inventory (CAHAI) and the ABILHAND Questionnaire, in individuals receiving stroke rehabilitation. Methods: The present study is a secondary analysis following the framework of the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). Individuals with chronic stroke (N = 113) were recruited from outpatient rehabilitation settings. Participants received 18 to 20 sessions of robot-assisted therapy, mirror therapy, combined therapy, or conventional rehabilitation for 4 to 6 weeks. The CAHAI, ABILHAND Questionnaire, and a comparison instrument, the Motor Activity Log (MAL), were administered twice at a 4- to 6-week interval to all participants. ABILHAND scores, in logits, were converted from raw ordinal scores into a linear measure. Results: There was medium to large correlation of the CAHAI and the MAL (ρ = 0.60-0.62, p < 0.01) as well as the ABILHAND Questionnaire and the MAL (ρ = 0.44-0.51, p < 0.01). Change scores from the initial measurement to the post-intervention measurement demonstrated small to medium correlation of the CAHAI and the MAL (ρ = 0.27-0.31, p < 0.01) and medium to large correlation of the ABILHAND Questionnaire and the MAL (ρ = 0.37-0.41, p < 0.01). Overall, 7 of 8 hypotheses were supported. The hypothesis testing regarding the construct validity and responsiveness of the CAHAI and ABILHAND Questionnaire was confirmed. Conclusion: The CAHAI and ABILHAND Questionnaire are both responsive and suitable to detect changes in bilateral arm functional daily activities in individuals with chronic stroke. Patient-reported outcome measures are recommended to use along with therapist-rated outcome measures for upper limb capacity evaluation in stroke rehabilitation. Further study with a prospective study design to capture specific clinical features of participants and the use of body-worn sensors, such as the arm accelerometer, is suggested.

The Role of Artificial Intelligence-Powered Imaging in Cerebrovascular Accident Detection.

Cerebrovascular accidents (CVAs) often occur suddenly and abruptly, leaving patients with long-lasting disabilities that place a huge emotional and economic burden on everyone involved. CVAs result when emboli or thrombi travel to the brain and impede blood flow; the subsequent lack of oxygen supply leads to ischemia and eventually tissue infarction. The most important factor determining the prognosis of CVA patients is time, specifically the time from the onset of disease to treatment. Artificial intelligence (AI)-assisted neuroimaging alleviates the time constraints of analysis faced using traditional diagnostic imaging modalities, thus shortening the time from diagnosis to treatment. Numerous recent studies support the increased accuracy and processing capabilities of AI-assisted imaging modalities. However, the learning curve is steep, and huge barriers still exist preventing a full-scale implementation of this technology. Thus, the potential for AI to revolutionize medicine and healthcare delivery demands attention. This paper aims to elucidate the progress of AI-powered imaging in CVA diagnosis while considering traditional imaging techniques and suggesting methods to overcome adoption barriers in the hope that AI-assisted neuroimaging will be considered normal practice in the near future. There are multiple modalities for AI neuroimaging, all of which require collecting sufficient data to establish inclusive, accurate, and uniform detection platforms. Future efforts must focus on developing methods for data harmonization and standardization. Furthermore, transparency in the explainability of these technologies needs to be established to facilitate trust between physicians and AI-powered technology. This necessitates considerable resources, both financial and expertise wise which are not available everywhere.

Care for the cerebrovascular accident survivors: experiences of family caregivers.

BACKGROUND: The role of family caregivers in the management of cerebrovascular accident survivors is invaluable. So far, there is a strong evidence affirming the effectiveness of family support for cerebrovascular accident survivors. Meanwhile, caring for cerebrovascular survivors can be labour and time intensive and pretty stressful for caregivers. The purpose of the study was to examine the lived experiences of family caregivers of cerebrovascular accident survivors in the Ho Municipality in the Volta Region of Ghana. This aims are to establish their caregivers' knowledge, preparedness, and impact of caregiving on the caregiver, and coping strategies caregivers adopted. METHODS: Using a four-item (with 14 prompts) interview guide and descriptive phenomenological approach, we gathered and analysed data from 37 family caregivers in the Ho Municipality of Ghana. RESULTS: We found that caregivers had limited knowledge about cerebrovascular disease-risk factors and were ill-prepared for their caregiving roles. Additionally, we found limited knowledge about coping strategies among the caregivers. We further report that some caregivers lost close relationships, and their jobs because of the caregiving, they also used fasting and prayer as coping strategies. CONCLUSIONS: Caregivers suffered broken relationship, loss their jobs and incomes due to their caregiving roles. Moreover, some engaged in fasting and prayers, and alcohol use to cope with the stress associated with caring for the cerebrovascular accident survivors. We discussed the potential implications of our findings on the realisation of the Sustainable Development Goal 3.4. The aim of this goal is to reduce by 75% premature deaths due to cerebrovascular and other non-communicable diseases by 2030.

The Effect of the Charlson Comorbidity Index On In-Hospital Complications, Hospital Length of Stay, Mortality, and Readmissions Among Patients Hospitalized for Acute Stroke.

Aim A notable number of people who develop stroke have comorbid medical conditions. The aim of this study is to evaluate the use of the Charlson Comorbidity Index (CCI) to predict in-hospital complications, mortality, length of stay, and readmission rates in stroke patients. Method It is a retrospective study that analyzed patients who were admitted for stroke in a six-month time duration. Stroke was classified into ischemic, hemorrhagic, or undetermined; hospital complications were classified into medical or neurological. Data regarding comorbidities, complications, length of stay, mortality, and readmissions were documented. Comorbidities were then classified by the CCI and split into four categories: zero, mild (1-2), moderate (3-4) and severe (5+). The data was analyzed using SPSS (IBM, Inc., Armonk, US). Results Four hundred and seventy-three adults aged above 18 were hospitalized for acute stroke. There was no correlation between the severity of the CCI score and mortality. Patients with ischemic stroke had a higher CCI correlated with readmission rate (p=0.026) and hospital complications (p=0.054). The two groups with the highest intensive care unit admission rate were mild, followed by the severe group (p=0.001). Our study also revealed that the patients with severe CCI scores had an increased readmission rate (p=0.001). Conclusion There is a correlation between a high CCI score and readmission rate, as well as CCI score with hospital complications in ischemic stroke. Further prospective studies of a longer duration can be undertaken to find further associations with the potential for this score to be used as a predictor in patients hospitalized for stroke.

Adaptation in the spinal cord after stroke: Implications for restoring cortical control over the final common pathway.

Control of voluntary movement is predicated on integration between circuits in the brain and spinal cord. Although damage is often restricted to supraspinal or spinal circuits in cases of neurological injury, both spinal motor neurons and axons linking these cells to the cortical origins of descending motor commands begin showing changes soon after the brain is injured by stroke. The concept of 'transneuronal degeneration' is not new and has been documented in histological, imaging and electrophysiological studies dating back over a century. Taken together, evidence from these studies agrees more with a system attempting to survive rather than one passively surrendering to degeneration. There tends to be at least some preservation of fibres at the brainstem origin and along the spinal course of the descending white matter tracts, even in severe cases. Myelin-associated proteins are observed in the spinal cord years after stroke onset. Spinal motor neurons remain morphometrically unaltered. Skeletal muscle fibres once innervated by neurons that lose their source of trophic input receive collaterals from adjacent neurons, causing spinal motor units to consolidate and increase in size. Although some level of excitability within the distributed brain network mediating voluntary movement is needed to facilitate recovery, minimal structural connectivity between cortical and spinal motor neurons can support meaningful distal limb function. Restoring access to the final common pathway via the descending input that remains in the spinal cord therefore represents a viable target for directed plasticity, particularly in light of recent advances in rehabilitation medicine.

Effects of high-intensity interval robot-assisted gait training on cardiopulmonary function and walking ability in chronic stroke survivors: A multicenter single-blind randomized controlled trial.

BACKGROUND: Chronic stroke can impair cardiopulmonary function, mobility, and daily activities. This study assessed the impact of robot-assisted gait training (RAGT) on such impairments. OBJECTIVE: To investigate the effects of robot-assisted gait training on cardiopulmonary function, walking ability, lower extremity function and strength, activities of daily living (ADLs), and blood test results among individuals with chronic stroke. METHODS: A multicenter, prospective, single-blinded, randomized controlled trial with 22 chronic stroke participants compared RAGT against a control exercise regimen. RAGT involved three days weekly sessions of high-intensity interval training for 8 weeks (24 sessions) with a Morning Walk® device. The control group also performed home exercises. (24 sessions) Measures included VO2max, Functional Ambulatory Category, 2-minute walk test, 10-meter walk test, Motricity Index-Lower, Korean version of the Fugl-Meyer Assessment Scale, Modified Barthel Index, Berg Balance Scale, muscle strength, InBody body composition, and blood tests (cholesterol, lipid, glucose). RESULTS: RAGT significantly improved VO2max, gait, balance, and lower limb strength compared with controls, with significant improvements in 2-minute walk test, 10-meter walk test, Motricity Index-Lower, and Fugl-Meyer Assessment outcomes. No changes were seen in muscle mass or blood markers. CONCLUSION: RAGT enhances cardiopulmonary function and ambulatory capacity in chronic stroke patients, underscoring its potential in stroke rehabilitation.

[Psychometric properties of performance outcome tools to assess sensitivity in subjects with stroke sequela: A systematic review]. / Propiedades psicométricas de herramientas de resultados de desempeño para evaluar la sensibilidad en sujetos con secuela de accidente cerebrovascular: revisión sistemática.

The objective was to perform a systematic review of those performance outcomes (HRD) tools that assess sensitivity in post-stroke subjects, as well as to know which of all is the most reliable and viable. The design was a systematic review. The following were included: HRD, developed in post-stroke subjects, of any etiology and period of evolution; 18 years of age or older and testing for sensitivity; results on psychometric properties. Excluded: self-reported results, the report of cross-cultural adaptation, designed through computerized means. 19 HRD were acquired. The psychometric properties analyzed were reliability, internal consistency, measurement error, construct validity, content validity, and sensitivity to change, the first being the most studied. Psychometric properties were identified, assessed, compared, and summarized. Of all of them, we recommend the use of the modified Erasmus Nottingham Sensory Assessment, as it presents the best degree of confidence in the evidence.

Mechanisms and benefits of cardiac rehabilitation in individuals with stroke: emerging role of its impact on improving cardiovascular and neurovascular health.

Human and animal studies have demonstrated the mechanisms and benefits of aerobic exercise for both cardiovascular and neurovascular health. Aerobic exercise induces neuroplasticity and neurophysiologic reorganization of brain networks, improves cerebral blood flow, and increases whole-body VO2peak (peak oxygen consumption). The effectiveness of a structured cardiac rehabilitation (CR) program is well established and a vital part of the continuum of care for people with cardiovascular disease. Individuals post stroke exhibit decreased cardiovascular capacity which impacts their neurologic recovery and extends disability. Stroke survivors share the same risk factors as patients with cardiac disease and can therefore benefit significantly from a comprehensive CR program in addition to neurorehabilitation to address their cardiovascular health. The inclusion of individuals with stroke into a CR program, with appropriate adaptations, can significantly improve their cardiovascular health, promote functional recovery, and reduce future cardiovascular and cerebrovascular events thereby reducing the economic burden of stroke.

Effects of core muscles strengthening exercises with routine physical therapy on trunk balance in stroke patients: A randomized controlled trial.

OBJECTIVE: To compare the effects of core muscle strengthening exercises with and without routine physical therapy on trunk balance in chronic stroke patients. METHODS: The randomised controlled trial was conducted at Mubarak Medical Complex, Sargodha, Pakistan, from October 28, 2021, to April 28, 2022, and comprised patients of either gender with chronic stroke aged 40-60 years. The subjects were randomised using the lottery method into group A that was managed with routine physical therapy, and group B which was further managed with core strengthening exercises. The intervention comprised 4 sessions per week for 8 weeks. Outcome was measured using Trunk Impairment Scale and Time Up and Go test. Data was collected at baseline, week 4 and post-intervention. Data was analysed using SPSS 23. RESULTS: Of the 80 individuals screened, 74(92.5%) were included. There were 37(50%) patients in group A; 30(81%) males and 7(19%) females with mean age 56.73±2.37 years. The remaining 37(50%) patients were in group B; 27(73%) males and 10(27%) females with mean age 55.65±2.88 years. Trunk balance and functional mobility improved significantly post-intervention in both groups (p<0.05), but group B values were significantly better compared to group A values (p<0.05). CONCLUSIONS: Core muscle strengthening exercises combined with routine physical therapy were found to be more effective compared to routine physical therapy alone in chronic stroke patients for improving trunk balance and functional mobility.

Oesophageal perforation by migrated Ryles tube.

A 72-year woman with a history of multiple cerebrovascular accidents presented with severe epigastric pain. An oesophageal perforation by the tip of a Ryles tube, which had migrated into the mediastinum, was diagnosed by radiography. An attempt at pushing the nasogastric tube into the stomach resulted in increasing the rupture to about 6 cm in size. Replacement by a triple-lumen nasojejunal feeding tube and subsequent feeding with c.1,400 calories per day enabled the perforation to close without further intervention.

Ischemic Stroke as an Initial Manifestation of Antiphospholipid Syndrome in an Adolescent: A Case Report.

Cerebrovascular diseases in pediatric patients are relatively rare. Ischemic stroke in adolescents is associated with a poor prognosis. The most common causes include systemic diseases, such as heart disease and hypercoagulation disorders. It is important to mention that one of the most common acquired hypercoagulation states is the antiphospholipid syndrome (APS). Patients with this disease may present stroke as the first clinical manifestation, which not only increases morbidity in these patients but presents a diagnostic challenge. This case presents one example of how APS can present as a pediatric stroke. The diagnostic approach should always be through the presence of specific antibodies accompanied by the presence of a thromboembolic episode proven by catheterization or an imaging study. In the brain, the preferred imaging study is magnetic resonance imaging. Management is based on anticoagulation therapy and continuous monitoring in the intensive care unit.

Mesenchymal stem cell therapy in ischemic stroke trials. A systematic review.

Cerebrovascular accidents, also known as strokes, are the leading cause of permanent disability in society, presenting significant socioeconomic and healthcare costs. They can be caused by ischemic factors or hemorrhages, with ischemic strokes being the most common among the population. Therapies for patients suffering from this condition are limited and primarily focus on acute-phase treatment. In recent years, there has been an increase in cellular therapies, employing Stem Cells to mitigate or eliminate the consequences arising from this disease. Mesenchymal Stem Cells (MSCs) hold substantial therapeutic potential in Nervous System pathologies due to their low antigenicity and capacity to differentiate into various human tissues, such as adipogenic, chondrogenic, and osteogenic tissues. This study conducts a literature review using the "clinical trials" and "Pubmed" database, summarizing all ongoing clinical trials for ischemic strokes that utilize MSCs as treatment.
