    Abstract: Background: Hemorrhagic foci surrounding the lacune in the long-term evolution of recent single subcortical infarcts (RSSIs) remains largely unexplored. We aimed to determine the prevalence, characteristics, and predictors of hemorrhagic foci in patients with RSSI. Methods: From a prospective, longitudinal study of RSSIs, we recruited patients who underwent multimodal MRI assessments at baseline and approximately one year after stroke onset. Hemorrhagic foci were identified using susceptibility-weighted imaging (SWI). Results: Among 72 patients with RSSI, nearly half (n = 35, 48.6%) had hemorrhagic foci within the index RSSI lesions on follow-up SWI. RSSIs with hemorrhagic foci formation were associated with a longer time to follow-up imaging (median 484 versus 425 days, P = 0.008) and higher likelihood of being located in the anterior circulation compared to those without hemorrhagic foci (100.0% versus 75.7%, P = 0.001). Hemorrhagic foci were also associated with larger lesion size (P 〈 0.001), higher proportion of cavitation formation (P = 0.042), and poorer functional outcome (P = 0.036). In the subset of RSSIs in the LSA territory, after adjustment for covariates, larger initial lesion volume (OR 1.63, 95% CI 1.06-2.53; P = 0.027) and greater reduction in LSA total length (OR 0.60, 95% CI 0.37-0.97; P = 0.035) were independently associated with hemorrhagic foci formation. Conclusion: Half of RSSI patients developed hemorrhagic foci within the lacunes during follow-up SWI. This hemorrhagic feature might represent hemosiderin deposits from a previously thrombosed perforating artery. The pathophysiologic mechanism and clinical implications remain to be determined.

    Abstract: Background— Excessive proliferation of pulmonary artery smooth muscle cells (PASMCs) plays an important role in the development of idiopathic pulmonary arterial hypertension (IPAH), whereas a rise in cytosolic Ca 2+ concentration triggers PASMC contraction and stimulates PASMC proliferation. Recently, we demonstrated that upregulation of the TRPC6 channel contributes to proliferation of PASMCs isolated from IPAH patients. This study sought to identify single-nucleotide polymorphisms (SNPs) in the TRPC6 gene promoter that are associated with IPAH and have functional significance in regulating TRPC6 activity in PASMCs. Methods and Results— Genomic DNA was isolated from blood samples of 237 normal subjects and 268 IPAH patients. Three biallelic SNPs, −361 (A/T), −254(C/G), and −218 (C/T), were identified in the 2000-bp sequence upstream of the transcriptional start site of TRPC6. Although the allele frequencies of the −361 and −218 SNPs were not different between the groups, the allele frequency of the −254(C→G) SNP in IPAH patients (12%) was significantly higher than in normal subjects (6%; P 〈 0.01). Genotype data showed that the percentage of −254G/G homozygotes in IPAH patients was 2.85 times that of normal subjects. Moreover, the −254(C→G) SNP creates a binding sequence for nuclear factor-κB. Functional analyses revealed that the −254(C→G) SNP enhanced nuclear factor-κB-mediated promoter activity and stimulated TRPC6 expression in PASMCs. Inhibition of nuclear factor-κB activity attenuated TRPC6 expression and decreased agonist-activated Ca 2+ influx in PASMCs of IPAH patients harboring the −254G allele. Conclusions— These results suggest that the −254(C→G) SNP may predispose individuals to an increased risk of IPAH by linking abnormal TRPC6 transcription to nuclear factor-κB, an inflammatory transcription factor.

    Abstract: Single subcortical infarction (SSI) is caused by two main etiological subtypes, which are branch atheromatous disease (BAD) and cerebral small vessel disease (CSVD)-related SSI. We applied the Beijing version of the Montreal Cognitive Assessment (MoCA-BJ), the Shape Trail Test (STT), and the Stroop Color and Word Test (SCWT) to investigate the differences in cognitive performance between these two subtypes of SSI. Methods: Patients with acute SSIs were prospectively enrolled. The differences of MoCA-BJ, STT, and SCWT between the BAD group and CSVD-related SSI group were analyzed. A generalized linear model was used to analyze the associations between SSI patients with different etiological mechanisms and cognitive function. We investigated the correlations between MoCA-BJ, STT, and SCWT using Spearman's correlation analysis and established cut-off scores for Shape Trail Test A (STT-A) and STT-B to identify cognitive impairment in patients with SSI. Results: This study enrolled a total of 106 patients, including 49 and 57 patients with BAD and CSVD-related SSI, respectively. The BAD group performances were worse than those of the CSVD-related SSI group for STT-A (83 [60.5–120.0] vs . 68 [49.0–86.5], P  = 0.01), STT-B (204 [151.5–294.5] vs . 153 [126.5–212.5], P  = 0.015), and the number of correct answers on Stroop-C (46 [41–49] vs . 49 [45–50], P  = 0.035). After adjusting for age, years of education, National Institutes of Health Stroke Scale and lesion location, the performance of SSI patients with different etiological mechanisms still differed significantly for STT-A and STT-B. Conclusions: BAD patients were more likely to perform worse than CSVD-related SSI patients in the domains of language, attention, executive function, and memory. The mechanism of cognitive impairment after BAD remains unclear.

    Abstract: Studies on the epidemiology of liver metastases (LM)-related mortality are rare. we aimed to describe the burden and trend of liver metastases in Pudong of Shanghai, which could be beneficial to cancer prevention. Methods We performed a retrospective population-based analysis of cancer mortality data with liver metastases in Shanghai Pudong from 2005 to 2021. Long-term trends in crude mortality rates (CMRs), age-standardized mortality rates worldwide, and rate of years of life lost (YLL) were analyzed by the Join-point regression model. In addition, we evaluate the impact of the demographic and nondemographic factors on the mortality of disease by the decomposition method. Results Cancer with liver metastases accounted for 26.68% of all metastases. The CMR and age-standardized mortality rates by Segi’s world population (ASMRW) of cancer with liver metastases were 15.12/105 person-years and 6.33/105 person-years, respectively. The YLL from cancer with liver metastases was 84 959.87 years, with the age group of 60–69 years having the highest YLL of 26 956.40 years. The top three cancer types in liver metastases are colorectal, gastric, and pancreatic cancer. The long-term trend of ASMRW significantly decreased by 2.31% per year ( P 〈 0.05). The ASMRW and YLL rates of those over 45 decreased year by year. Particularly striking was the 70–79 age group. Although the overall mortality of cancer with liver metastases decreased, there was still a significant upward trend toward an increased mortality rate caused by cancer with liver metastases in aging patients. Conclusion Liver metastases were a common site of metastases in patients with cancers originating from the digestive system. The disease burden caused by cancer with liver metastases provides valuable evidence for cancer management.

    Abstract: The uptake of proven stroke treatments varies widely. We aimed to determine the association of evidence‐based processes of care for acute ischemic stroke ( AIS ) and clinical outcome of patients who participated in the HEADPOST (Head Positioning in Acute Stroke Trial), a multicenter cluster crossover trial of lying flat versus sitting up, head positioning in acute stroke. Methods and Results Use of 8 AIS processes of care were considered: reperfusion therapy in eligible patients; acute stroke unit care; antihypertensive, antiplatelet, statin, and anticoagulation for atrial fibrillation; dysphagia assessment; and physiotherapist review. Hierarchical, mixed, logistic regression models were performed to determine associations with good outcome (modified Rankin Scale scores 0–2) at 90 days, adjusted for patient and hospital variables. Among 9485 patients with AIS, implementation of all processes of care in eligible patients, or “defect‐free” care, was associated with improved outcome (odds ratio, 1.40; 95% CI, 1.18–1.65) and better survival (odds ratio, 2.23; 95% CI , 1.62–3.09). Defect‐free stroke care was also significantly associated with excellent outcome (modified Rankin Scale score 0–1) (odds ratio, 1.22; 95% CI , 1.04–1.43). No hospital characteristic was independently predictive of outcome. Only 1445 (15%) of eligible patients with AIS received all processes of care, with significant regional variations in overall and individual rates. Conclusions Use of evidence‐based care is associated with improved clinical outcome in AIS . Strategies are required to address regional variation in the use of proven AIS treatments.

    Abstract: It is unclear whether patients with different stroke/transient ischemic attack etiologies benefit differently from gene-directed dual antiplatelet therapy. This study explored the efficacy and safety of ticagrelor-aspirin versus clopidogrel-aspirin in transient ischemic attack or minor stroke with different causes in the CHANCE-2 trial (Clopidogrel in High-Risk Patients With Acute Nondisabling Cerebrovascular Events-II). METHODS: This was a prespecified analysis of the CHANCE-2 trial, which enrolled 6412 patients with minor stroke or transient ischemic attack who carried CYP2C19 loss-of-function alleles. Patients with centralized evaluation of TOAST (Trial of ORG 10172 in Acute Stroke Treatment) classification of large-artery atherosclerosis, small-vessel occlusion, and stroke of undetermined cause were included. The primary efficacy outcome was new stroke, and the primary safety outcome was severe or moderate bleeding, both within 90 days. Cox proportional hazards models were used to assess the interaction of TOAST classification with the effects of dual antiplatelet therapy with ticagrelor-aspirin versus clopidogrel-aspirin. RESULTS: A total of 6336 patients were included in this study. In patients administered ticagrelor-aspirin and clopidogrel-aspirin, respectively, stroke recurred in 85 (9.8%) and 88 (10.7%) patients with large-artery atherosclerosis (hazard ratio, 0.86 [95% CI, 0.63–1.18]; P =0.34); 32 (3.6%) and 61 (7.0%) patients with small-vessel occlusion (hazard ratio, 0.51 [95% CI, 0.33–0.79]; P =0.002); and 68 (4.8%) and 87 (5.9%) patients with stroke of undetermined cause (hazard ratio, 0.80 [95% CI, 0.58–1.10]; P =0.17), with P =0.08 for the treatment×cause subtype interaction effect. There were no significant differences in severe or moderate bleeding events in patients with different cause and different treatment. CONCLUSIONS: In this prespecified analysis of the CHANCE-2 trial, the efficacy and safety of ticagrelor-aspirin versus clopidogrel-aspirin in preventing new stroke were consistent in patients with different causes. The influence of stroke cause on benefit of gene-guided antiplatelet therapy should be explored by further trials. REGISTRATION: URL: https://www.clinicaltrials.gov ; Unique identifier: NCT04078737.

    Abstract: Breastfeeding confers substantial benefits to child health and has also been associated with lower risk of maternal cardiovascular diseases ( CVDs ) in later life. However, the evidence on the effects of CVD is still inconsistent, especially in East Asians, in whom the frequency and duration of breastfeeding significantly differ from those in the West. Methods and Results In 2004–2008, the nationwide China Kadoorie Biobank recruited 0.5 million individuals aged 30 to 79 years from 10 diverse regions across China. During 8 years of follow‐up, 16 671 incident cases of coronary heart disease and 23 983 cases of stroke were recorded among 289 573 women without prior CVD at baseline. Cox regression yielded adjusted hazard ratios ( HR s) and 95% CIs for incident CVD by breastfeeding. Overall, ≈99% of women had given birth, among whom 97% reported a history of breastfeeding, with a median duration of 12 months per child. Compared with parous women who had never breastfed, ever breastfeeding was associated with a significantly lower risk of CVD , with adjusted HR s of 0.91 (95% CI, 0.84–0.99) for coronary heart disease and 0.92 (95% CI, 0.85–0.99) for stroke. Women who had breastfed for ≥24 months had an 18% ( HR, 0.82; 0.77–0.87) lower risk of coronary heart disease and a 17% ( HR, 0.83; 0.79–0.87) lower risk of stroke compared with women who had never breastfed. Among women who ever breastfed, each additional 6 months of breastfeeding per child was associated with an adjusted HR of 0.96 (95% CI, 0.94–0.98) for coronary heart disease and 0.97 (95% CI, 0.96–0.98) for stroke. Conclusions Among Chinese women, a history of breastfeeding was associated with an ≈10% lower risk of CVD in later life and the magnitude of the inverse association was stronger among those with a longer duration of breastfeeding.
