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.

From A to E: Uniting vitamins against stroke risk-A systematic review and network meta-analysis.

BACKGROUND AND AIM: Stroke represents a significant public health challenge, necessitating the exploration of preventive measures. This network meta-analysis aimed to assess the efficacy of different vitamin treatments compared to a placebo in preventing stroke. METHODS: A systematic electronic search in databases including PubMed, EmBASE, Web of Science, clinicaltrials.gov, and Google Scholar until 31 May 2023 was conducted, to identify published studies investigating the association between vitamin intake and the risk of stroke. Pooled risk ratio (RR) with 95% confidence intervals (CIs) was calculated using a frequentist network meta-analysis. Furthermore, we ranked vitamins based on p-scores, facilitating a comparative assessment of their effectiveness in preventing stroke. RESULTS: A total of 56 studies, including 17 randomized controlled trials (RCTs) and 39 cohort studies were analyzed. Direct estimates obtained from network meta-analysis, we found that vitamin A (RR: .81 [.72-.91]), vitamin B-complex (RR: .85 [.74-.97]), vitamin B6 (RR: 79 [.68-.92]), folate (RR: .86 [.75-.97]), vitamin C (RR: .77 [.70-.85]) and vitamin D (RR: .73 [.64-.83]) were significantly associated with a decreased stroke risk. However, no significant association was observed for vitamin B2, vitamin B12, and vitamin E. Subsequent to network meta-analysis, vitamins were ranked in decreasing order of their efficacy in stroke prevention based on p-score, with vitamin D (p-score = .91), vitamin C (p-score = .79), vitamin B6 (p-score = .70), vitamin A (p-score = .65), vitamin B-complex (p-score = .53), folate (p-score = .49), vitamin B2 (p-score = .39), vitamin E (p-score = .28), vitamin B12 (.13) and placebo (.10). CONCLUSION: Our study has established noteworthy connections between vitamin A, vitamin B-complex, vitamin B6, folate, vitamin C, and vitamin D in the realm of stroke prevention. These findings add substantial weight to the accumulating evidence supporting the potential advantages of vitamin interventions in mitigating the risk of stroke. However, to solidify and validate these observations, additional research is imperative. Well-designed clinical trials or cohort studies are needed to further explore these associations and formulate clear guidelines for incorporating vitamin supplementation into effective stroke prevention strategies.

Beyond gait speed: exploring the added value of Inertial Measurement Unit-based measurements of gait in the estimation of the walking ability in daily life.

BACKGROUND: Gait speed is often used to estimate the walking ability in daily life in people after stroke. While measuring gait with inertial measurement units (IMUs) during clinical assessment yields additional information, it remains unclear if this information can improve the estimation of the walking ability in daily life beyond gait speed. OBJECTIVE: We evaluated the additive value of IMU-based gait features over a simple gait-speed measurement in the estimation of walking ability in people after stroke. METHODS: Longitudinal data during clinical stroke rehabilitation were collected. The assessment consisted of two parts and was administered every three weeks. In the first part, participants walked for two minutes (2MWT) on a fourteen-meter path with three IMUs attached to low back and feet, from which multiple gait features, including gait speed, were calculated. The dimensionality of the corresponding gait features was reduced with a principal component analysis. In the second part, gait was measured for two consecutive days using one ankle-mounted IMU. Next, three measures of walking ability in daily life were calculated, including the number of steps per day, and the average and maximal gait speed. A gait-speed-only Linear Mixed Model was used to estimate the association between gait speed and each of the three measures of walking ability. Next, the principal components (PC), derived from the 2MWT, were added to the gait-speed-only model to evaluate if they were confounders or effect modifiers. RESULTS: Eighty-one participants were measured during rehabilitation, resulting in 198 2MWTs and 135 corresponding walking-performance measurements. 106 Gait features were reduced to nine PCs with 85.1% explained variance. The linear mixed models demonstrated that gait speed was weakly associated with the average and maximum gait speed in daily life and moderately associated with the number of steps per day. The PCs did not considerably improve the outcomes in comparison to the gait speed only models. CONCLUSIONS: Gait in people after stroke assessed in a clinical setting with IMUs differs from their walking ability in daily life. More research is needed to determine whether these discrepancies also occur in non-laboratory settings, and to identify additional non-gait factors that influence walking ability in daily life.

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.

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.

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.

Human-centered design of a novel soft exosuit for post-stroke gait rehabilitation.

BACKGROUND: Stroke remains a major cause of long-term adult disability in the United States, necessitating the need for effective rehabilitation strategies for post-stroke gait impairments. Despite advancements in post-stroke care, existing rehabilitation often falls short, prompting the development of devices like robots and exoskeletons. However, these technologies often lack crucial input from end-users, such as clinicians, patients, and caregivers, hindering their clinical utility. Employing a human-centered design approach can enhance the design process and address user-specific needs. OBJECTIVE: To establish a proof-of-concept of the human-centered design approach by refining the NewGait® exosuit device for post-stroke gait rehabilitation. METHODS: Using iterative design sprints, the research focused on understanding the perspectives of clinicians, stroke survivors, and caregivers. Two design sprints were conducted, including empathy interviews at the beginning of the design sprint to integrate end-users' insights. After each design sprint, the NewGait device underwent refinements based on emerging issues and recommendations. The final prototype underwent mechanical testing for durability, biomechanical simulation testing for clinical feasibility, and a system usability evaluation, where the new stroke-specific NewGait device was compared with the original NewGait device and a commercial product, Theratogs®. RESULTS: Affinity mapping from the design sprints identified crucial categories for stakeholder adoption, including fit for females, ease of donning and doffing, and usability during barefoot walking. To address these issues, a system redesign was implemented within weeks, incorporating features like a loop-backed neoprene, a novel closure mechanism for the shoulder harness, and a hook-and-loop design for the waist belt. Additional improvements included reconstructing anchors with rigid hook materials and replacing latex elastic bands with non-latex silicone-based bands for enhanced durability. Further, changes to the dorsiflexion anchor were made to allow for barefoot walking. Mechanical testing revealed a remarkable 10-fold increase in durability, enduring 500,000 cycles without notable degradation. Biomechanical simulation established the modularity of the NewGait device and indicated that it could be configured to assist or resist different muscles during walking. Usability testing indicated superior performance of the stroke-specific NewGait device, scoring 84.3 on the system usability scale compared to 62.7 for the original NewGait device and 46.9 for Theratogs. CONCLUSION: This study successfully establishes the proof-of-concept for a human-centered design approach using design sprints to rapidly develop a stroke-specific gait rehabilitation system. Future research should focus on evaluating the clinical efficacy and effectiveness of the NewGait device for post-stroke rehabilitation.

Test-Retest Reliability, Clinical Usefulness, and Telephone Application of the Work Limitation Questionnaire in Individuals Who Returned to Work After Stroke.

PURPOSES: To measure the test-retest reliability and the clinical usefulness of the Work Limitation Questionnaire, and to compare the in-person with the telephone application. METHODS: Cross-sectional, exploratory study. The Work Limitation Questionnaire was answered three times: twice in person, to measure test-retest reliability and clinical usefulness, and once, by telephone, to measure the validity of the telephone application. RESULTS: Fifty-six individuals (32 men) with mild to moderate disabilities after stroke were included. Test-retest reliability was very high (ICC 0.96; 95% CI 0.94 to 0.98; p < 0.01), the clinical usefulness was high (9 out of 12 points), and the correlation between in-person and telephone applications was high (ρ = 0.7; 95% CI 0.5 to 0.9; p < 0.01). The average productivity loss was 4% (SD 5, min-max 0 to 15%). CONCLUSIONS: The Work Limitation Questionnaire showed adequate test-retest reliability and clinical usefulness in individuals with stroke. The telephone application produced comparable results to in-person applications. The participants reported low productivity loss, which may be related to the mild impairments of the included sample.

Feasibility and user-experience of a virtual environment for social connection and education after stroke: A pilot study.

OBJECTIVES: To evaluate the feasibility and usability of stroke survivor participation in an 8-week virtual environment intervention that provides opportunities for social support exchanges, social network interactions, and recovery education. MATERIALS AND METHODS: A single-group, pre- and post-test measure design was used. Descriptive statistics were used to examine enrollment and retention rates, proportion of questionnaires completed, and virtual environment process data (e.g., number of log-ins) and usability scores. Changes in pre- and post-intervention questionnaire (e.g., usability, social support, depression, anxiety, loneliness, and self-efficacy) scores were explored using Wilcoxon signed-rank tests and paired t-test. RESULTS: Fifteen (65 %) of the eligible stroke survivors enrolled (60 % white, 27 % black), 12 (80 %) had an ischemic stroke, ages ranged from 33 to 74 years (mean 44 years), and mean months since stroke was 33 ± 23. Retention and questionnaire completion rates were both 93 % (n = 14). Survivors logged into the virtual environment a total of 122 times, logged an average of 49 min/log-in, and 12 (80 %) attended support groups and social activities. Median usability score indicated lower than average usability. Improvement trends in social support, loneliness, and depressive symptoms were found, but significant changes in mean questionnaire scores were not found. CONCLUSIONS: Overall, the results suggest that using a virtual environment to foster social support exchanges, social network interactions, and recovery education after stroke is feasible. Similar to other chronic disease populations, stroke survivor adoption of a virtual environment likely requires ongoing technical assistance, repetition of instructions, and opportunities for practice to reinforce engagement. TRIAL REGISTRATION: NCT05487144.

The effect of sodium-glucose transporter 2 inhibitors on stroke in patients with type 2 diabetes: A meta-analysis.

OBJECTIVES: To provide an update on the effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors on stroke in patients with type 2 diabetes (T2D). METHODS: PubMed, Embase, and Cochrane Library were systematically searched for randomized controlled trials (RCTs) comparing SGLT2 inhibitors versus placebo or other therapies in patients with T2D and reporting stroke endpoint. We computed the risk ratios (RRs) to binary endpoints, with 95 % confidence intervals (CIs). RESULTS: A total of 71 RCTs and 105,914 patients were included, of whom 62,488 (59 %) were randomized to the SGLT2 inhibitors group. The follow-up ranged from 12 weeks to 4.2 years. There were no significant differences between groups in all types of stroke (RR 0.96; 95 % CI 0.89-1.04), ischemic stroke (RR 0.89; 95 % CI 0.76-1.04), and transient ischemic attack (RR 0.96; 95 % CI 0.79-1.16). Patients on SGLT2 inhibitors experienced lower rates of hemorrhagic stroke (RR 0.62; 95 % CI 0.39-0.98). In the subgroup analysis of the type of drug, sotagliflozin significantly reduced all types of stroke (RR 0.74; 95 % CI 0.56-0.97). CONCLUSION: In this meta-analysis of 71 RCTs comprising 105,914 patients with T2D, SGLT2 inhibitors were not associated with a reduced risk of stroke and transient ischemic attack compared to placebo or other therapies; however, there was a trend toward reduced risk of hemorrhagic stroke. Among all SGLT2 inhibitors, sotagliflozin significantly reduced the risk of stroke.

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.

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.

Comparison of upper extremity and transfemoral access for fenestrated-branched endovascular aortic repair.

OBJECTIVE: The use of upper extremity (UE) access is an accepted and often implemented approach for fenestrated/branched endovascular aortic aneurysm repair (F-BEVAR). The advent of steerable sheaths has enabled the performance of F-BEVAR using a total transfemoral (TF) approach without UE access, potentially decreasing the risks of cerebral embolic events. The purpose of the present study was to assess the outcomes of F-BEVAR using UE vs TF access. METHODS: Prospectively collected data from nine physician-sponsored investigational device exemption studies at U.S. centers were analyzed using a standardized database. All patients were treated for complex abdominal aortic aneurysms (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs) using industry-manufactured fenestrated and branched stent grafts between 2005 and 2020. The outcomes were compared between patients who had undergone UE vs total TF access. The primary composite outcome was stroke or transient ischemia attack (TIA) and 30-day or in-patient mortality during the perioperative period. The secondary outcomes included technical success, local access-related complications, and perioperative mortality. RESULTS: Among 1681 patients (71% men; mean age, 73.43 ± 7.8 years) who had undergone F-BEVAR, 502 had had CAAAs (30%), 535 had had extent IV TAAAs (32%), and 644 had had extent I to III TAAAs (38%). UE access was used for 1103 patients (67%). The right side was used for 395 patients (24%) and the left side for 705 patients (42%). UE access was preferentially used for TAAAs (74% vs 47%; P < .001). In contrast, TF access was used more frequently for CAAAs (53% vs 26%; P < .01). A total of 38 perioperative cerebrovascular events (2.5%), including 32 strokes (1.9%) and 6 TIAs (0.4%), had occurred. Perioperative cerebrovascular events had occurred more frequently with UE access than with TF access (2.8% vs 1.2%; P = .036). An individual component analysis of the primary composite outcome revealed a trend for more frequent strokes (2.3% vs 1.2%; P = .13) and TIAs (0.54% vs 0%; P = .10) in the UE access group. On multivariable analysis, total TF access was associated with a 60% reduction in the frequency of perioperative cerebrovascular events (odds ratio, 0.39; P = .029). No significant differences were observed between UE and TF access in the technical success rate (96.5% vs 96.8%; P = .72), perioperative mortality (2.9% vs 2.6%; P = .72), or local access-related complications (6.5% vs 5.5%; P = .43). CONCLUSIONS: In the present large, multicenter, retrospective analysis of prospectively collected data, a total TF approach for F-BEVAR was associated with a lower rate of perioperative cerebrovascular events compared with UE access. Although the cerebrovascular event rate was low with UE access, the TF approach offered a lower risk of stroke and TIA. UE access will continue to play a role for appropriately selected patients requiring more complex repairs with anatomy not amenable to the TF approach.

Hypertensive disorders of pregnancy and long-term risk of maternal stroke-a systematic review and meta-analysis.

OBJECTIVE: Hypertensive disorders of pregnancy are associated with a long-term risk for cardiovascular disease among parous patients later in life. However, relatively little is known about whether hypertensive disorders of pregnancy are associated with an increased risk for ischemic stroke or hemorrhagic stroke in later life. This systematic review aimed to synthesize the available literature on the association between hypertensive disorders of pregnancy and the long-term risk for maternal stroke. DATA SOURCES: PubMed, Web of Science, and CINAHL were searched from inception to December 19, 2022. STUDY ELIGIBILITY CRITERIA: Studies were only included if the following criteria were met: case-control or cohort studies that were conducted with human participants, were available in English, and that measured the exposure of a history of hypertensive disorders of pregnancy (preeclampsia, gestational hypertension, chronic hypertension, or superimposed preeclampsia) and the outcome of maternal ischemic stroke or hemorrhagic stroke. METHODS: Three reviewers extracted the data and appraised the study quality following the Meta-analyses of Observational Studies in Epidemiology guidelines and using the Newcastle-Ottawa scale for risk of bias assessment. RESULTS: The primary outcome was any stroke (undifferentiated) and secondary outcomes included ischemic stroke and hemorrhagic stroke. The protocol for this systematic review was registered in the International Prospective Register of Systematic Reviews under identifier CRD42021254660. Of 24 studies included (10,632,808 study participants), 8 studies examined more than 1 outcome of interest. Hypertensive disorders of pregnancy were significantly associated with any stroke (adjusted risk ratio, 1.74; 95% confidence interval, 1.45-2.10). Preeclampsia was significantly associated with any stroke (adjusted risk ratio, 1.75; 95% confidence interval, 1.56-1.97), ischemic stroke (adjusted risk ratio, 1.74; 95% confidence interval, 1.46-2.06), and hemorrhagic stroke (adjusted risk ratio, 2.77; 95% confidence interval, 2.04-3.75). Gestational hypertension was significantly associated with any stroke (adjusted risk ratio, 1.23; 95% confidence interval, 1.20-1.26), ischemic stroke (adjusted risk ratio, 1.35; 95% confidence interval, 1.19-1.53), and hemorrhagic stroke (adjusted risk ratio, 2.66; 95% confidence interval, 1.02-6.98). Chronic hypertension was associated with ischemic stroke (adjusted risk ratio, 1.49; 95% confidence interval, 1.01-2.19). CONCLUSION: In this meta-analysis, exposure to hypertensive disorders of pregnancy, including preeclampsia and gestational hypertension, seems to be associated with an increased risk for any stroke and ischemic stroke among parous patients in later life. Preventive interventions may be warranted for patients who experience hypertensive disorders of pregnancy to reduce their long-term risk for stroke.

Results of a 12-Month Randomized Controlled Trial Testing the Efficacy of the Diabetes Prevention Program Group Lifestyle Balance (DPP-GLB) for People Post Stroke (GLB-CVA).

BACKGROUND: Experience of stroke is associated with an increased risk for diabetes and metabolic syndrome, yet few interventions exist that have been tailored to the population's unique needs. PURPOSE: To examine adherence and efficacy of the Diabetes Prevention Program Group Lifestyle Balance program (DPP-GLB) modified for individuals post stroke (GLB-CVA) using a randomized controlled trial. METHODS: Adults (18-85 years of age), >12 months post stroke, and body mass index ≥25 kg/m2 were included in this study. Sixty-five individuals were assigned to either the GLB-CVA intervention or a 6-month wait-list control. Participants completed the 12-month GLB-CVA intervention, with attendance and assessment of weight, anthropometric, biomarker, functional, and patient reported outcome data collected at baseline, 3, 6, and 12 months. RESULTS: High attendance (90%) and dietary and activity tracking (71%) suggest high adherence to the 12-month GLB-CVA. Six-month randomized controlled trial data indicate significant weight loss (p = .005) in the GLB-CVA group (7.4 ± 13.6 lbs, 3.65%) compared with the wait-list control (0.1 ± 10.1 lbs, 0%), and improvements in arm circumference (p = .04), high-density lipoprotein (HDL) cholesterol (p = .028), 8-year diabetes risk (p = .011), and pain interference (p < .001). Combined 12-month data showed participants lost 10.1 ± 16.8 lbs (4.88%) and improved waist circumference (p = .001), HbA1c (3.6%), diastolic blood pressure (p < .001), pain (p = .001), social participation (p = .025), and eating practices (p = .01) and habits (p < .001). CONCLUSIONS: Engagement in the GLB-CVA can result in weight loss and improved health for individuals who are overweight or obese following stroke. Future efforts should examine effectiveness in real-world settings and focus on knowledge translation efforts.

Experience of stroke is associated with an added risk for diabetes and metabolic syndrome, yet few interventions exist that have been tailored to the population's unique needs. Our team delivered a health promotion program called the Diabetes Prevention Program Group Lifestyle Balance (DPP-GLB) modified for individuals post stroke (GLB-CVA) living in the community. We enrolled 65 adults (18­85 years of age), who were at least 12 months post stroke, and had body mass index of at least 25 kg/m2. Participants were randomized to either the GLB-CVA intervention or a 6-month wait-list control. Outcome data were collected at baseline, 3, 6, and 12 months. Results showed high participant attendance (90%) and tracking completion (71%). Participants in the GLB-CVA intervention group lost significantly more weight (3.65%) and had greater improvements in arm circumference, HDL cholesterol, 8-year diabetes risk, and pain than participants in the wait-list control. Combined 12-month data showed participants lost 4.88% of their body weight and improved waist circumference, blood sugar (HbA1c), diastolic blood pressure, pain, social participation, eating practices, and habits. Due to these results, we concluded that engagement in the GLB-CVA can result in weight loss and improved health for individuals who are overweight or obese following stroke.

Potential cerebrovascular accident signal for risankizumab: A disproportionality analysis of the FDA Adverse Event Reporting System (FAERS).

AIMS: The interleukin-23 (IL-23) inhibitor risankizumab was recently approved for the treatment of moderate-to-severe plaque psoriasis in the United States. Low rates of cerebrovascular accident (CVA) were observed in risankizumab-treated patients during clinical trials. The aim of this study was to determine whether risankizumab may be associated with CVA in a real-world setting. METHODS: A retrospective disproportionality analysis was conducted utilizing postmarketing adverse event reports submitted to the US Food and Drug Administration Adverse Event Reporting System (FAERS) through the fourth quarter of 2021. A custom query consisting of 22 CVA-related Medical Dictionary for Regulatory Activities (MedDRA) preferred terms previously reported in clinical trials of plaque psoriasis medications was used to identify cases. Disproportionality was measured by calculating reporting odds ratios (ROR) and 95% confidence intervals (CI), whereby the lower limit of a 95% CI >1.0 and ≥ three cases was considered a signal. RESULTS: Risankizumab was associated with significantly disproportionate CVA reporting compared to all other drugs in FAERS (ROR 2.48; 95% CI 2.14-2.88) as well as 11 alternative plaque psoriasis therapeutics across five pharmacologic classes. The largest disproportionality signals for risankizumab were identified relative to apremilast (ROR 9.07; 95% CI 7.56-10.89), ixekizumab (ROR 6.75; 95% CI 5.14-8.86), guselkumab (ROR 6.74; 95% CI 4.68-9.71), certolizumab (ROR 5.70; 95% CI 4.74-6.85) and etanercept (ROR 4.91; 95% CI 4.21-5.73). CONCLUSION: This study detected a previously unreported signal of disproportionate CVA reporting with the real-world use of risankizumab. Further long-term observational data will be necessary to better characterize this unconfirmed potential safety signal.

Periodontitis and atherosclerotic cardiovascular disease: A critical appraisal.

In spite of intensive research efforts driving spectacular advances in terms of prevention and treatments, cardiovascular diseases (CVDs) remain a leading health burden, accounting for 32% of all deaths (World Health Organization. "Cardiovascular Diseases (CVDs)." WHO, February 1, 2017, https://www.who.int/news-room/fact-sheets/detail/cardiovascular-diseases-(cvds)). Cardiovascular diseases are a group of disorders affecting the heart and blood vessels. They encompass a collection of different conditions, among which atherosclerotic cardiovascular disease (ASCVD) is the most prevalent. CVDs caused by atherosclerosis, that is, ASCVD, are particularly fatal: with heart attack and stroke being together the most prevalent cause of death in the world. To reduce the health burden represented by ASCVD, it is urgent to identify the nature of the "residual risk," beyond the established risk factors (e.g., hypertension) and behavioral factors already maximally targeted by drugs and public health campaigns. Remarkably, periodontitis is increasingly recognized as an independent cardiovascular risk factor.

Responsiveness of the Reaching Performance Scale for Stroke.

OBJECTIVE: The objective of the study was to estimate the internal and external responsiveness of the Reaching Performance Scale for Stroke (RPSS) in individuals with stroke. DESIGN: Retrospective analysis of data from 4 randomized controlled trials. SETTING: Recruitment locations spanning rehabilitation centers and hospitals in Canada, Italy, Argentina, Peru, and Thailand. PARTICIPANTS: Data from 567 participants (acute to chronic stroke; N=567) were available. INTERVENTIONS: All 4 studies involved training using virtual reality for upper limb rehabilitation. MAIN OUTCOME MEASURES: RPSS and upper extremity Fugl-Meyer Assessment (FMA-UE) scores. Responsiveness was quantified for all data and across different stages of stroke. Internal responsiveness of the RPSS was quantified as effect-sizes calculated using post and preintervention change data. External responsiveness was quantified using orthogonal regressions between FMA-UE and RPSS scores. The area under the Receiver Operating Characteristic curve (AUC) was quantified based on the ability of RPSS scores to detect change above FMA-UE minimal clinically important different values across different stages of stroke. RESULTS: The RPSS had high internal responsiveness overall and across the acute or subacute and chronic stages of stroke. For external responsiveness, orthogonal regression analyses indicated that change in FMA-UE scores had positive moderate correlations with both RPSS Close and Far Target scores for all data and across the acute or subacute and chronic stages of stroke (0.6

Sex differences in acute ischemic stroke presentation are a matter of infarct location.

INTRODUCTION: Recognition of stroke by Emergency Medical Services (EMS) is critical to initiate rapid emergency department treatment. Most prehospital stroke screening tools rely heavily on presentation with the classic symptoms of facial droop, speech changes, unilateral weakness. However, women may be less likely to present with classic symptoms and may also have different distributions of stroke by anatomical location. This study seeks to determine the association between biological sex, presentation with classic symptoms, and the location of the infarcted tissue. METHODS: This is a retrospective cohort study. Data from electronic health records were extracted for patients with acute ischemic stroke who presented via EMS to a single Comprehensive Stroke Center between January 1, 2018 and December 31, 2020. We used descriptive statistics characterize the cohort. Multivariable logistic regression identified factors associated with classic symptom presentation (facial droop, speech changes, and/or unilateral weakness). Biological sex, location of the infarct, stroke etiology, age and the interaction between sex and infarct location were assessed as covariates. RESULTS: There were 364 (58.6%) males and 257 (41.1%) females with an acute ischemic stroke included in this study. EMS documented one or more classic symptoms in 125 (72.3%) males and 161 (67.9%) females. There were no baseline differences in infarct location or presentation with classic symptoms as documented by EMS comparing males and females. Multivariate logistic regression found no association between biological sex and presentation with classic symptoms (Odds Ratio 1.08; 95% CI 0.58 to 1.55) after controlling for age, stroke location, etiology of stroke or the interaction between sex and infarct location. Presence of an anterior circulation infarct compared to posterior circulation infarct was positively associated with a classic presentation to EMS (Odds Ratio 3.41; 95% CI 2.15 to 5.41). CONCLUSIONS: This study found no difference in the frequency of patient presentation with classic stroke symptoms based on biological sex alone, nor a significant different in distribution of infarcts between males and females. Infarct location (i.e., involving the anterior circulation) was associated with a classic presentation. This suggests that the likelihood of presenting with classic stroke symptoms is not influenced by sex, but rather the location of the infarct.

Massive MCA stroke requiring alteplase followed by thrombectomy in a 34-year-old female with alport syndrome.

34-year-old-female with a medical history significant for Alport's syndrome, chronic kidney disease on dialysis, and hypertension, was brought to the emergency department for sudden onset aphasia and facial droop that began 30 min prior to arrival. She denied a history of prior strokes, recent illness, or fever. The vital signs on arrival as follows: blood pressure 151/71 mmHg, temperature of 98.4F, pulse of 77 beats/min, and respirations of 16 breaths/min. Upon examination, she appeared in mild distress with a left sided facial droop, right sided hemiparesis, and expressive aphasia, only answering to yes/no. Neurological examination revealed: expressive aphasia, intact sensation throughout the face and bilateral extremities, no effort in the right arm against gravity, some effort against gravity of the right leg, left arm and left leg had muscle strength of 5/5. Patient had an NIH stroke scale of 8. The remainder of the exam was unremarkable. Radiographic imaging with CT revealed no intracranial hemorrhage (Fig. 1) and the patient was given alteplase (tPA) injection 5.6 mg within 1 h of her arrival to the Emergency Department. After administration of tPA a CT perfusion scan was performed (Fig. 2). Imaging demonstrated decreased cerebral blood flow and prolonged mean transit time within the majority of the left middle cerebral artery territory, sparing the basal ganglia. This indicated a left middle cerebral artery M1 occlusion. Neurosurgery was consulted and the patient underwent thrombectomy. Her hospital course was complicated by hemorrhagic transformation (HT) on hospital day 2. The patient underwent MRI that showed a large left MCA distribution acute infarction with focal reperfusion hemorrhage and parenchymal hematoma measuring approximately 3 cm in each dimension (Fig. 3). This finding prompted emergent decompression and hemicraniectomy on day 2 of hospitalization. The patient was discharged on hospital day 17 to a rehab center.
