Background Stroke is a significant global health issue, with a high prevalence of morbidity, mortality, and disability. We can classify strokes into two types: ischemic and hemorrhagic, with ischemic strokes being more common. This study aims to investigate the role of high-density lipoprotein (HDL), C-reactive protein (CRP), and serum ferritin levels in people who have had ischemic and hemorrhagic strokes in order to identify possible biomarkers for diagnosis and treatment. Materials and methods This observational cross-sectional comparative study included 100 stroke patients (50 ischemic and 50 hemorrhagic) from Dr. D. Y. Patil Medical College, Hospital and Research Centre, Dr. D. Y. Patil Vidyapeeth (Deemed to be University), Pune. We collected data through clinical evaluations, laboratory tests, and imaging studies. We measured and analyzed HDL, CRP, and serum ferritin levels using appropriate statistical tests, such as the chi-square test and Student t-test, with a 95% confidence interval (CI) and a 5% p-value for significance. Results The mean age for ischemic stroke patients was 55.92 years, whereas for hemorrhagic stroke patients, it was 58.68 years. The study found significant differences in HDL, CRP, and ferritin levels between the two groups. The mean HDL level for ischemic stroke patients was significantly lower at 25.10 mg/dL, compared to 40.57 mg/dL in hemorrhagic stroke patients, with a p-value of <0.001. The mean CRP level was higher in ischemic stroke patients (28.90 mg/L) compared to hemorrhagic stroke patients (22.80 mg/L), with a p-value of <0.001. Ferritin levels were also higher in hemorrhagic stroke patients (587.98 ng/mL) compared to ischemic stroke patients (473.16 ng/mL), with a statistically significant p-value of <0.001. Conclusion This study highlights the significant role of HDL, CRP, and serum ferritin levels in distinguishing between ischemic and hemorrhagic stroke patients. Elevated HDL levels may protect against ischemic strokes due to their anti-inflammatory properties, while higher CRP levels in ischemic strokes indicate a strong inflammatory response. Elevated ferritin levels in hemorrhagic strokes suggest increased oxidative stress and inflammation.

UNASSIGNED: Despite advancements in stroke care, challenges persist in timely triage and treatment initiation to prevent the burden of stroke-related disabilities. Although nuclear medicine has shown promise, no imaging technique has yet provided a sufficiently rapid, precise, and cost-effective approach to routine stroke management. This study aims to review the clinical application of nuclear medicine in stroke diagnosis and treatment.
UNASSIGNED: A systematic search of the Cochrane, EU Clinical Trials Register, ISRCTN, the International Stroke Trial, and the ClinicalTrials.gov database was conducted to find all registered trials reporting nuclear medicine\'s clinical applications in stroke up to June 07, 2024.
UNASSIGNED: Among the 220 screened trials, 51 (36 interventional; 15 observational) met the eligibility criteria. Participants were older than 18 years old, with only six studies including pediatric under 17 years old, with a total of 11,262 stroke (9,232 ischemic; 2,030 haemorrhagic) participants. The bias risk varied across trials but remained mostly low to moderate.
UNASSIGNED: The review highlighted nuclear medicine\'s significant contributions to stroke diagnosis and management, notably through mobile stroke units, pre-hospital acute stroke magnetic resonance image (MRI) based biomarkers, and MRI-based stroke mechanisms for 4D flow nuclear imaging. These advancements have generally reduced treatment delays and enhance clinical outcomes post-stroke. Specifically, radiopharmaceutical radiotracers can effectively discriminate between strokes and mimics, particularly in high-risk patients. Integrating novel positron emission tomography (PET) radiotracer 18F glycoprotein 1 and radionuclide angiography may improve sensitivity and specificity in thrombi detection for decisions regarding stenting or carotid endarterectomy, and the single-photon emission computed tomography and PET integration with ferumoxytol radiotracer-enhanced MRI enables functional imaging for evaluating cerebral perfusion, metabolic activity, and neuroinflammatory markers post-stroke. Overall, the integration of nuclear medicine into multimodal imaging equipment like computed-tomography PET and MRI-PET offers a more comprehensive picture of the brain. Nevertheless, further research is needed on novel stroke imaging techniques and standardization across stroke centers for optimal performance.

UNASSIGNED: The impact of different stroke types on specific activities of daily living (ADL) is unclear.
UNASSIGNED: To investigate how differences between intracerebral hemorrhage (ICH) and cerebral infarction (CI) affect improvement of ADL in patients with stroke within a hospital by focusing on the sub-items of the Functional Independence Measure (FIM).
UNASSIGNED: Patients with first-stroke hemiplegia (n = 212) were divided into two groups: ICH (86 patients) and CI (126 patients). Primary assessments included 13 motor and 5 cognitive sub-items of the FIM assessed at admission and discharge. Between-group comparisons and multiple regression analyses were performed.
UNASSIGNED: Upon admission, the ICH group exhibited significantly lower FIM scores than those of the CI group across various activities, including grooming, dressing (upper body and lower body), toileting, bed/chair transfer, toilet transfer, walking/wheelchair, and stairs. Age and FIM motor scores at admission influenced both groups\' total FIM motor scores at discharge, whereas the duration from onset affected only the CI group.
UNASSIGNED: Several individual FIM motor items were more adversely affected by ICH than by CI. Factors related to ADL at discharge may differ depending on stroke type. Recognizing these differences is vital for efficient rehabilitation practices and outcome prediction.

Why lower low-density lipoprotein cholesterol (LDL-C) was associated with a decreased atherosclerotic cardiovascular disease (ASCVD) risk but an increased hemorrhagic stroke (HS) risk in hypertensive adults remains unclear. We examined whether the inverse LDL-C-HS association partly arises from its effect on ASCVD. We estimated separable effects of LDL-C on HS outside (i.e., separable direct effect) or only through its effect on ASCVD (i.e., separable indirect effect) in hypertensive adults from the Chinese Multi-provincial Cohort Study. We quantified such effects using numbers needed to treat (NNT) to prevent or cause an extra HS based on the restricted mean event-free time till a 25-year follow-up. LDL-C $<$ 70 mg/dL was not associated with an increased HS risk compared to LDL-C $\\ge$ 70 mg/dL regarding total and separable direct effects. However, a small separable indirect effect (i.e., NNT to harm: 9722 participants) was noted and validated via a series of sensitivity analyses. Moreover, modified effects were observed, particularly in the 35-49-year age group, men, and those with SBP $\\ge$ 140 mm Hg. These results suggest the inverse LDL-C-HS association in hypertensive adults is partly due to its effect on ASCVD. A better understanding of such associations would provide more enlightening into stroke prevention.

BACKGROUND: Accumulating evidence suggests that cardiac findings after stroke are an important, yet understudied, manifestation of brain-heart interactions. Our aim was to investigate and compare cardiac findings after different cerebrovascular events (acute ischemic stroke, transient ischemic attack, and hemorrhagic stroke).
RESULTS: There were 7113 patients screened who were treated between December 2013 and December 2020 at the University Hospital Zurich for ischemic stroke, transient ischemic attack, and hemorrhagic stroke. Seven hundred twenty-one patients without evidence of previous cardiac disease or presumed cardioembolic origin of their cerebrovascular disease and with at least 1 cardiac checkup were included. Clinical reports from the year following disease onset were screened for new cardiac findings, which were categorized as arrhythmia/electrocardiographic changes, myocardial alterations, valvular abnormalities, and coronary perfusion insufficiency. Differences in proportions of findings among groups were analyzed using the Pearson χ2 test or Fisher exact test. ECG changes were observed in 81.7% (n=474) of patients with ischemic stroke, 71.4% (n=70) of patients with transient ischemic attack, and 55.8% (n=24) of patients with hemorrhagic stroke (P<0.001). Myocardial alterations occurred often in all 3 groups (60.9% ischemic stroke [n=353], 59.2% transient ischemic attack [n=58], 44.2% hemorrhagic stroke [n=19]; P=0.396).
CONCLUSIONS: Cardiac findings are frequent in patients with cerebrovascular disease, even without prior cardiac problems or suspected cardiac cause. Similarities, especially between patients with ischemic stroke and transient ischemic attack, were observed. Our data suggest that all patients with acute cerebrovascular events should receive thorough workup searching for cardiac manifestations.

BACKGROUND: Acute myocardial injury is associated with poor outcomes in patients with acute ischemic stroke, but its prognostic significance in patients with spontaneous intracerebral hemorrhage remains unclear. We investigated whether acute myocardial injury and the direction of the cardiac troponin I (cTnI) change (rising versus falling) affect post-intracerebral hemorrhage outcomes.
RESULTS: We re-analyzed the FAST (Factor-Seven-for-Acute-Hemorrhagic-Stroke) trial. Acute myocardial injury was defined as at least 1 cTnI value above the upper reference limit with a rise/fall of >20%. Logistic regression tested for associations (1) between acute myocardial injury (presence versus absence) and poor outcome (modified Rankin Scale 4-6) and mortality at 15 and 90 days; (2) among 3 groups (rising versus falling versus no acute myocardial injury) and outcomes. Among the 841 FAST participants, 785 patients were included. Acute myocardial injury was detected in 29% (n=227); 170 had rising cTnI. At 15 and 90 days, respectively, those with acute myocardial injury had higher odds of poor outcome (adjusted odds ratio) ([aOR] 2.3 [95% CI, 1.3-3.9]); and adjusted odds ratio 2.5 [95% CI, 1.6-3.9];, and higher odds of mortality (adjusted odds ratio 2.4 [95% CI, 1.4-4.3]; and adjusted odds ratio 2.2 [CI, 1.3-3.6]) than patients without. There was no interaction between FAST group assignment and myocardial injury, and associations between myocardial injury and outcomes were consistent across group assignments. Rising cTnI was associated with the highest risk of poor outcomes and mortality.
CONCLUSIONS: In this secondary analysis of the FAST trial, acute myocardial injury was common and associated with poor outcomes. The direction of the cTnI change might provide additional risk stratification after intracerebral hemorrhage.

BACKGROUND: Adults with congenital heart disease (CHD) are at increased risk of stroke but high-quality population level data on stroke incidence in these patients are scant.
RESULTS: A retrospective whole-population Western Australian cohort of adult patients with CHD aged 18 to 64 years was created and followed from January 2000 to December 2017 using linked hospital data. Stroke incidence rates within the adult cohort with CHD were calculated and compared with the general population via direct standardization. A nested case-control design assessed predictors of ischemic and hemorrhagic stroke within the cohort. Among 7916 adults with CHD, 249 (3.1%) incident strokes occurred at a median age of 47 years; 186 (2.3%) ischemic, 33 (0.4%) hemorrhagic and 30 (0.4%) unspecified strokes. Ischemic and hemorrhagic stroke incidence was, respectively, 9 and 3 times higher in adults with CHD than the general population. Absolute risk was low with annual rates of 0.26% (ischemic) and 0.05% (hemorrhagic). Highest rates were observed in adults with shunt and left-sided lesions. Predictors of ischemic stroke in adults with CHD included recent cardiac surgery, left-sided valve repair/replacements, shunt lesions, and traditional risk factors (hypertension, infective endocarditis, peripheral vascular disease, and tobacco use). Mental health disorders and increasing Charlson\'s comorbidity scores were strongly associated with higher risk of ischemic and hemorrhagic stroke. The CHA2DS2VASc score was associated with ischemic stroke incidence.
CONCLUSIONS: This study provides the first population-based stroke incidence estimates for adults with CHD in Australia, showing elevated stroke risk across different CHD lesions. It highlights the potential clinical importance of managing comorbidities, especially mental health.

BACKGROUND: A technologically integrated, multidisciplinary approach to stroke rehabilitation service was delivered and embedded into conventional health care practice. This article reports an evaluation of cost-effectiveness analysis of a new Virtual Multidisciplinary Stroke Care Clinic (VMSCC) service for community-dwelling survivors of stroke.
RESULTS: A randomized controlled trial was conducted. Adults with a first/recurrent ischemic/hemorrhagic stroke were recruited from 10 hospitals. Eligible participants were randomly assigned to receive the VMSCC service (individual virtual consultations with a registered nurse, home blood pressure telemonitoring, and unlimited access to an online resource platform) plus usual care or usual care alone. Cost-effectiveness analyses were performed based on incremental cost-effectiveness ratios expressed as incremental cost per emergency admission reduced, and day of hospitalization reduced over the study period. A total of 256 participants (intervention group n=141 versus control group n=115) with complete cost and health care use data were included in the cost-effectiveness analyses. The VMSCC service, on average, resulted in a greater reduction in the number of emergency admission (-0.06 [95% bootstrapped CI, -0.14 to 0.01]) and fewer days of hospitalization (-0.08, [95% bootstrapped CI -0.40 to 0.24]) but incurred a higher total cost of HK$375 (95% bootstrapped CI, -2103 to 2743) compared with the usual care. The incremental cost-effectiveness ratios of the VMSCC service compared with the usual care were HK$6070 and HK$4826 per an emergency admission and a day of hospital stay reduced respectively.
CONCLUSIONS: The study provides preliminary but not confirmative evidence that the VMSCC service could be more effective but more costly than usual care in reducing health service use.

OBJECTIVE: To study the severity of systemic metabolic dysfunction in various types of stroke and determine the parameters of optimal energy and protein supply for this category of patients in the presence of severe neurological deficit (National Institutes of Health Stroke Scale - NIHSS score of 15 points or more) during different periods of the disease.
METHODS: The retrospective study included 512 patients with acute cerebrovascular accident (ACVA) who received nutritional support (NS) for 10 days or more: 367 (71.7%) people with ischemic stroke (IS) and 145 (28.3%) - with hemorrhagic stroke (HS). The course of stroke in all patients included in the study was accompanied by severe and extremely severe neurological disorders (15 points or more on the NIHSS scale). Energy expenditure and the severity of the catabolic reaction of the body were studied by dynamic assessment of indirect calorimetry indicators and actual nitrogen losses.
RESULTS: More than 99% of patients received tube feeding. Using the method of indirect calorimetry, the ranges of energy expenditure during stroke were determined: for IS - 1600-2100 kcal/day (24-26 kcal/kg/day), for HS - 1900-2600 kcal/day (26-30 kcal/kg/day) in depending on the period of the disease. The average nitrogen losses at all stages of the disease in patients with IS and HS were comparable. In IS, these amounts were 19 g/day (0.25 g/kg/day), which corresponds to 119 g/day of protein (1.56 g/kg/day of protein), and in HS patients lost an average of 18.9 g/day of nitrogen (0.24 g/kg/day) or 118 g/day of protein (1.5 g/kg/day of protein). The maximum nitrogen losses were observed in the period from 10 to 20 days of illness and amounted to 24.7 g/day in patients with HS (0.31 g/kg/day or 1.93 g/kg/day protein), and in patients with IS - 24.5 g/day (0.29 g/kg/day or 1.81 g/kg/day protein).
CONCLUSIONS: An identified trend towards a decrease in mortality in patients with acute stroke with energy supply in the amount of 27-28 kcal/kg/day and protein consumption in the amount of 1.3-1.4 g/kg/day compared with patients receiving 20-21 kcal/kg /day and 1-1.2 g/kg/day of protein requires further prospective randomized studies.
UNASSIGNED: Изучить выраженность системной метаболической дисфункции при различных вариантах острых нарушений мозгового кровообращения (ОНМК) и определить параметры оптимального энергетического и белкового обеспечения данной категории больных при наличии выраженного неврологического дефицита в разные периоды заболевания.
UNASSIGNED: В ретроспективное исследование вошли 512 пациентов с ОНМК, получавшие нутритивную поддержку (НП) на протяжении 10 сут и более: 367 (71,7%) человек с ишемическим инсультом (ИИ) и 145 (28,3%) — с геморрагическим инсультом (ГИ). Течение ОНМК у всех вошедших в исследование больных сопровождалось тяжелыми и крайне тяжелыми неврологическими нарушениями (15 баллов и более по шкале инсульта Национальных институтов здоровья (NIHSS)). Энергетические траты и выраженность катаболической реакции организма исследовались путем динамической оценки показателей непрямой калориметрии и фактических потерь азота.
UNASSIGNED: Более 99% больных получали зондовое питание. Методом непрямой калориметрии определены диапазоны энерготрат при ОНМК: при ИИ — 1600—2100 ккал/сут (24—26 ккал/кг/сут), при ГИ — 1900—2600 ккал/сут (26—30 ккал/кг/сут) в зависимости от периода заболевания. Средние потери азота на всех этапах заболевания у больных с ИИ и ГИ были сопоставимыми: при ИИ — 19 г/сут (0,25 г/кг/сут), что соответствует 119 г/сут белка (1,56 г/кг/сут белка), а при ИИ — 18,9 г/сут (0,24 г/кг/сут), или 118 г/сут белка (1,5 г/кг/сут белка). Максимальные потери азота отмечались в период с 10-х по 20-е сутки болезни и составили у пациентов с ГИ 24,7 г/сут (0,31 г/кг/сут, или 1,93 г/кг/сут белка), а у больных с ИИ 24,5 г/сут (0,29 г/кг/сут, или 1,81 г/кг/сут белка).
UNASSIGNED: Выявленная тенденция к снижению летальности больных с ОНМК при энергетическом обеспечении в объеме 27—28 ккал/кг/сут и потреблении белка в количестве 1,3—1,4 г/кг/сут по сравнению с пациентами, получавшими 20—21 ккал/кг/сут и 1—1,2 г/кг/сут белка, требует дальнейших проспективных рандомизированных исследований.

BACKGROUND: High blood pressure (BP) increases recurrent stroke risk.
RESULTS: We assessed hypertension prevalence, treatment, control, medication adherence, and predictors of uncontrolled BP 90 days after ischemic or hemorrhagic stroke among 561 Mexican American and non-Hispanic White (NHW) survivors of stroke from the BASIC (Brain Attack Surveillance in Corpus Christi) cohort from 2011 to 2014. Uncontrolled BP was defined as average BP ≥140/90 mm Hg at 90 days poststroke. Hypertension was uncontrolled BP or antihypertensive medication prescribed or hypertension history. Treatment was antihypertensive use. Adherence was missing zero antihypertensive doses per week. We investigated predictors of uncontrolled BP using logistic regression adjusting for patient factors. Median (interquartile range) age was 68 (59-78) years, 64% were Mexican American, and 90% of strokes were ischemic. Overall, 94.3% of survivors of stroke had hypertension (95.6% Mexican American versus 92.0% non-Hispanic White; P=0.09). Of these, 87.9% were treated (87.3% Mexican American versus 89.1% non-Hispanic White; P=0.54). Among the total population, 38.3% (95% CI, 34.4%-42.4%) had uncontrolled BP. Among those with uncontrolled BP prescribed an antihypertensive, 84.5% reported treatment adherence (95% CI, 78.8%-89.3%). Uncontrolled BP 90 days poststroke was less likely in patients with stroke who had a primary care physician (adjusted odds ratio [aOR], 0.45 [95% CI, 0.24-0.83]; P=0.01), greater stroke severity (aOR per-1-point-higher National Institutes of Health Stroke Scale score, 0.96 [95% CI, 0.93-0.99]; P=0.02), or more depressive symptoms (aOR per-1-point-higher Personal Health Questionnaire Depression Scale-8 score, 0.95 [95% CI, 0.92-0.99] among those with a history of hypertension at baseline; P=0.009).
CONCLUSIONS: Greater than one third of survivors of stroke have uncontrolled BP at 90 days poststroke in this population-based study. Interventions are needed to improve BP control after stroke.
