UNASSIGNED: Cerebrovascular diseases of the brain are usually defined by transient ischemic attacks and strokes. However, they can also cause brain injuries without neurological events. Silent brain infarcts (SBI) and leukoaraiosis are symptoms of both vascular and neurological abnormalities. This study aims to investigate the association between SBI, leukoaraiosis, and middle-aged patients with ischemic stroke.
UNASSIGNED: A single-center retrospective study of 50 middle-aged, ischemic stroke patients were studied from November 2022 and May 2023. The patients were divided into two groups based on the presence or absence of leukoaraiosis. History taking, physical examination, brain CT scan, and MRI were all part of the diagnostic process. Metabolic syndrome (MetS) was also assessed through various factors. The statistical analysis included descriptive statistics, logistic regression analysis, and chi-square test.
UNASSIGNED: Out of the cohort comprising 50 patients, characterized by a mean age of 52.26 years (SD 5.29), 32 were male, constituting 64% of the sample. Among these patients, 26 individuals exhibited leukoaraiosis, with 17 of them (65.4%) also presenting with SBI. Moreover, within this cohort, 22 patients were diagnosed with MetS, representing 84.6% of those affected. The Multivariate logistic regression analysis showed a strong and independent association between leukoaraiosis and SBI. Individuals with leukoaraiosis were nearly five times more likely to have SBI compared to those without leukoaraiosis.
UNASSIGNED: The study highlights leukoaraiosis as a significant risk factor for SBI, alongside MetS. Advanced imaging techniques have facilitated their detection, revealing a higher prevalence among stroke patients, particularly associated with age and hypertension. Further research is needed to fully understand their complex relationship and develop better management strategies for cerebrovascular diseases, ultimately improving patient outcomes.

UNASSIGNED: Japan has experienced 8 waves of the coronavirus disease 2019 (COVID-19) outbreak over the past 3 years, resulting in an increasing number of deaths and incidence of severe infections. This study aimed to analyze the data from the Japanese inflammatory bowel disease (IBD) patients with COVID-19 registry (J-COSMOS) up to the eighth wave to investigate the clinical course of IBD patients with COVID-19 and factors contributing to disease severity.
UNASSIGNED: In this multicenter, observational, cohort study, we analyzed a cohort of 1308 IBD patients diagnosed with COVID-19, enrolled across 77 participating facilities in the J-COSMOS registry from June 2020 to December 2022. Data on age, sex, IBD (classification, treatment, and activity), and COVID-19 (symptoms, severity, and treatment) were analyzed.
UNASSIGNED: The majority of patients (76%) were in clinical remission. According to the World Health Organization classification of COVID-19 severity, 98.4% of IBD patients had nonsevere disease, while 1.6% of patients had severe or critical disease. COVID-19 did not affect disease activity in most IBD patients. Stepwise logistic regression analysis revealed that high body mass index, and cerebrovascular disease were risk factors for severe COVID-19. Corticosteroids could affect COVID-19 severity, whereas anti-tumor necrosis factor α antibodies and thiopurines were associated with a reduced risk of severe COVID-19. No deaths were observed among IBD patients with COVID-19 registered in this cohort.
UNASSIGNED: The impact of COVID-19 on IBD disease activity and factors associated with COVID-19 severity were consistent with findings of previous reports. No deaths in Japanese patients with IBD were observed.

Air pollution poses significant health risks to urban areas, with limited focus on the chronic association of PM2.5 and its constituents on cerebrovascular diseases (CERs), especially regarding the joint associations. This study explores the individual and joint associations between PM2.5 constituents and CER hospitalization risks through a cohort analysis of 36,271 adults in the Pearl River Delta, South China, from 2015 to 2020. Cox proportional hazards regression and quantile-based g-computation models were used to quantify the individual and joint associations of annual mean concentrations of PM2.5 constituents with hospitalization for CERs. 1151 participants were hospitalized due to CERs during the five-year follow-up period. Joint associations analyses identified that one quartile increase in co-exposure may result in hazard ratios of 1.530 (1.441-1.623), 1.840 (1.710-1.980), and 1.609 (1.491-1.737) for CERs, total, and ischemic stroke hospitalization, respectively. The adverse effect was primarily driven by organic matter and chlorine. Men, those with a history of tobacco or alcohol use or with low residential greenness, were more susceptible to CERs hospitalization following PM2.5 constituents co-exposure. Upcoming strategies should focus on monitoring and regulating PM2.5 constituents, encouraging healthy lifestyles, and enhancing urban greenery.

(1) Background: Previous studies have identified disparities in stroke care and outcomes by sex. Therefore, the main objective of this study was to evaluate the average cost of stroke care and the existence of differences in care provision by biological sex. (2) Methods: This observational study adhered to the recommendations of the STROBE statement. The calculation of costs was performed based on the production cost of the service or the rate paid for a set of services, depending on the availability of the corresponding information. (3) Results: A total of 336 patients were included, of which 47.9% were women, with a mean age of 73.3 ± 11.6 years. Women were typically older, had a higher prevalence of hypertension (p = 0.005), lower pre-stroke proportion of mRS 0-2 (p = 0.014), greater stroke severity (p < 0.001), and longer hospital stays (p = 0.017), and more were referred to residential services (p = 0.001) at 90 days. Women also required higher healthcare costs related to cardiovascular risk factors, transient ischemic strokes, institutionalization, and support needs; in contrast, they necessitated lower healthcare costs when undergoing endovascular therapy and receiving rehabilitation services. The unadjusted averaged cost of stroke care was EUR 22,605.66 (CI95% 20,442.8-24,768.4), being higher in women [p = 0.027]. The primary cost concept was hospital treatment (38.8%), followed by the costs associated with dependence and support needs (36.3%). At one year post-stroke, the percentage of women not evaluated for a degree of dependency was lower (p = 0.008). (4) Conclusions: The total unadjusted costs averaged EUR 22,605.66 (CI95% EUR 20,442.8-24,768.4), being higher in women compared to men. The primary cost concept was hospital treatment (38.8%), followed by the costs associated with dependence and support needs (36.3%).

BACKGROUND: Scarce data exist about clinical/radiological differences between acute ischemic strokes diagnosed in the emergency room (AISER) and stroke chameleons (SCs). We aimed at describing the differences observed in a comprehensive stroke center in Chile.
METHODS: Prospective observational study of patients with ischemic stroke syndromes admitted to the emergency room (ER) of Clínica Alemana between December 2014 and October 2023.
RESULTS: 1,197 patients were included; of these 63 (5.2%, 95% CI: 4.1-6.6) were SC; these were younger (p < 0.001), less frequently hypertensive (p = 0.03), and they also had lower systolic (SBP) (p < 0.001), diastolic blood pressures (DBP) (p = 0.011), and NIHSS (p < 0.001). Clinically, they presented less frequently gaze (p = 0.008) and campimetry alterations (p = 0.03), facial (p < 0.001) and limb weakness (left arm [p = 0.004], right arm (p = 0.041), left leg (p = 0.001), right leg p = 0.0029), sensory abnormalities (p < 0.001), and dysarthria (p < 0.001). Neuroradiological evaluations included less frequently large vessel occlusions (p = 0.01) and other stroke locations (p = 0.005); they also differed in their etiologies (p < 0.001). Brainstem strokes (p < 0.001) and extinction/inattention symptoms (p < 0.001) were only seen in AISER. In multivariate analysis, younger age (OR: 0.945; 95% CI: 0.93-0.96), DBP (OR: 0.97; 95% CI, 0.95-0.99), facial weakness (OR: 0.39; 95% CI: 0.19-0.78), sensory abnormities (OR: 0.16.18; 95% CI, 0.05-0.4), infratentorial location (OR: 0.36; 95% CI, 0.15-0.78), posterior circulation involvement (OR: 3.02; 95% CI, 1.45-6.3), cardioembolic (OR: 3.5; 95% CI, 1.56-7.99), and undetermined (OR: 2.42; 95% CI, 1.22-4.7; 95%) etiologies, remained statistically significant. A stepwise analysis including only clinical elements present on the patient\'s arrival to the ER, demonstrates that age (OR: 0.95; 95% CI: 0.94-0.97), DBP (OR: 0.97; 95% CI, 0.95-0.99), the presence of atrial fibrillation (OR: 2.22; 95% CI, 1.04-4.75, NIHSS (OR: 0.88; 95% CI, 0.71-0.89) and the presence in NIHSS of 1a level of consciousness (OR: 5.66; CI: 95% 1.8-16.9), 1b level of consciousness questions (OR: 3.023; 95% CI, 1.35-6.8), facial weakness (OR: 0.3; CI: 95% 0.17-0.8), and sensory abnormalities (OR: 0.27; 95% CI, 0.1-0.72) remained statistically significant.
CONCLUSIONS: SC had clinical and radiological differences compared to AISER. An additional relevant finding is that neurological symptoms in a patient with atrial fibrillation, even with a negative diffusion-weighted imaging, should be carefully evaluated as a potential stroke until other causes are satisfactorily ruled out.

OBJECTIVE: Cerebral Vasomotor Reactivity (VMR) is a property of cerebral hemodynamics that protects from cerebrovascular disease. We aimed to explore the VMR longitudinal changes in patients with acute non-disabling stroke/Transient Ischemic Attack (TIA) to understand its implication in stroke ethiopatogenesis.
METHODS: VMR by Transcranial Doppler Breath Holding test was performed at 48-72 h from stroke onset (T1) and after 6 months (T2) on MCA of the non-affected hemisphere and PCA of the affected hemisphere.
RESULTS: We consecutively enrolled 124 patients with a median age of 66.0 (IQR 54.75-74.25) years with a median NIHSS 2 (IQR 1-3). Both MCA (1.38 %/s SD 0.58) and PCA (1.35 %/s SD 0.75) BHI at T1 did not differ among different stroke subtypes (p=0.067 and p=0.350; N=124). MCA and PCA BHI decreased from T1 to T2 (respectively 1.39 %/s SD 0.56 vs 1.18%/s SD 0.44 and 1.30 %/s SD 0.69 vs 1.20 %/s SD 0.51; N=109) regardless of ethiopatogenesis (respectively p<0.0001 and p=0.111).
CONCLUSIONS: The VMR is higher in acute phase than at 6 months in patients with non-disabling stroke/TIA, regardless of etiopathogenesis. The higher VMR in acute phase could be sustained by an increased Cerebral Blood Flow due to collateral circulation activation supporting the ischemic zone.

UNASSIGNED: Ensuring effective return to work following acquired brain injuries is crucial from the perspectives of both quality of life and the economy. However, techniques of occupational therapy support for return to work remain relatively unelucidated.
UNASSIGNED: To clarify the specific contents of occupational therapy required for work and work support for clients with acquired brain injuries.
UNASSIGNED: An interview-based survey was conducted with participants who had >10 years of occupational therapy experience and had provided work support. We selected participants via snowball sampling. Data were analyzed using thematic analysis.
UNASSIGNED: A total of 20 participants (15 women and 5 men; 6, 12, 1, and 1 in their 30s, 40s, 50s, and 60s, respectively) were included. Six concepts were generated on reviewing the support for work items considered important by the occupational therapist as follows: \"Support for vocational life,\" \"Support for interpersonal skills,\" \"Support for work,\" \"Support for illness, disability, and awareness,\" \"Support for utilization of compensation measures,\" and \"Support for goal setting.\"
UNASSIGNED: We clarified the specific contents of work support, including support for vocational life and support for work, that is administered by occupational therapists who provide work support for clients with acquired brain injury. The insights from the study improve understanding of OTs\' roles and contributions in supporting clients with acquired brain injuries in returning to work.

Accelerated by the adoption of remote monitoring during the COVID-19 pandemic, interest in using digitally captured behavioral data to predict patient outcomes has grown; however, it is unclear how feasible digital phenotyping studies may be in patients with recent ischemic stroke or transient ischemic attack. In this perspective, we present participant feedback and relevant smartphone data metrics suggesting that digital phenotyping of post-stroke depression is feasible. Additionally, we proffer thoughtful considerations for designing feasible real-world study protocols tracking cerebrovascular dysfunction with smartphone sensors.

BACKGROUND: People with type 2 diabetes (T2D) are at elevated risk of cardiovascular disease (CVD) including stroke, yet existing real-world evidence (RWE) on the clinical and economic burden of stroke in this population is limited. The aim of this cohort study was to evaluate the clinical and economic burden of stroke among people with T2D in France.
METHODS: We conducted a retrospective RWE study using data from the nationally representative subset of the French Système National des Données de Santé (SNDS) database. We assessed the incidence of stroke requiring hospitalization between 2012 and 2018 among T2D patients. Subsequent clinical outcomes including CVD, stroke recurrence, and mortality were estimated overall and according to stroke subtype (ischemic versus hemorrhagic). We also examined the treatment patterns for glucose-lowering agents and CVD agents, health care resource utilization and medical costs.
RESULTS: Among 45,331 people with T2D without baseline history of stroke, 2090 (4.6%) had an incident stroke requiring hospitalization. The incidence of ischemic stroke per 1000 person-years was 4.9-times higher than hemorrhagic stroke (6.80 [95% confidence interval (CI) 6.47-7.15] versus 1.38 [1.24-1.54]). During a median follow-up of 2.4 years (interquartile range 0.6; 4.4) from date of index stroke, the rate of CVD, stroke recurrence and mortality per 1000 person-years was higher among hemorrhagic stroke patients than ischemic stroke patients (CVD 130.9 [107.7-159.0] versus 126.4 [117.2-136.4]; stroke recurrence: 86.7 [66.4-113.4] versus 66.5 [59.2-74.6]; mortality 291.5 [259.1-327.9] versus 144.1 [134.3-154.6]). These differences were not statistically significant, except for mortality (adjusted hazard ratio 1.95 [95% CI 1.66-2.92]). The proportion of patients prescribed glucagon-like peptide-1 receptor agonists increased from 4.2% at baseline to 6.6% during follow-up. The proportion of patients prescribed antihypertensives and statins only increased slightly following incident stroke (antihypertensives: 70.9% pre-stroke versus 76.7% post-stroke; statins: 24.1% pre-stroke versus 30.0% post-stroke). Overall, 68.8% of patients had a subsequent hospitalization. Median total medical costs were €12,199 (6846; 22,378).
CONCLUSIONS: The high burden of stroke among people with T2D, along with the low proportion of patients receiving recommended treatments as per clinical guidelines, necessitates a strengthened and multidisciplinary approach to the CVD prevention and management in people with T2D.
