Prevalence, patterns, and predictors of patient-reported non-motor outcomes at 30 days after acute stroke: Prospective observational hospital cohort study.

BACKGROUND: Adverse non-motor outcomes are common after acute stroke and likely to substantially affect quality of life, yet few studies have comprehensively assessed their prevalence, patterns, and predictors across multiple health domains. AIMS: We aimed to identify the prevalence, patterns, and the factors associated with non-motor outcomes 30 days after stroke. METHODS: This prospective observational hospital cohort study-Stroke Investigation in North and Central London (SIGNAL)-identified patients with acute ischemic stroke or intracerebral hemorrhage (ICH) admitted to the Hyperacute Stroke Unit (HASU) at University College Hospital (UCH), London, between August 1, 2018 and August 31, 2019. We assessed non-motor outcomes (anxiety, depression, fatigue, sleep, participation in social roles and activities, pain, bowel function, and bladder function) at 30-day follow-up using the Patient-Reported Outcome Measurement Information System-Version 29 (PROMIS-29) scale and Barthel Index scale. RESULTS: We obtained follow-up data for 605/719 (84.1%) eligible patients (mean age 72.0 years; 48.3% female; 521 with ischemic stroke, 84 with ICH). Anxiety (57.0%), fatigue (52.7%), bladder dysfunction (50.2%), reduced social participation (49.2%), and pain (47.9%) were the commonest adverse non-motor outcomes. The rates of adverse non-motor outcomes in ⩾ 1, ⩾ 2 and ⩾ 3 domains were 89%, 66.3%, and 45.8%, respectively; in adjusted analyses, stroke due to ICH (compared to ischemic stroke) and admission stroke severity were the strongest and most consistent predictors. There were significant correlations between bowel dysfunction and bladder dysfunction (κ = 0.908); reduced social participation and bladder dysfunction (κ = 0.844); and anxiety and fatigue (κ = 0.613). We did not identify correlations for other pairs of non-motor domains. CONCLUSION: Adverse non-motor outcomes were very common at 30 days after stroke, affecting nearly 90% of evaluated patients in at least one health domain, about two-thirds in two or more domains, and almost 50% in three or more domains. Stroke due to ICH and admission stroke severity were the strongest and most consistent predictors. Adverse outcomes occurred in pairs of domains, such as with anxiety and fatigue. Our findings emphasize the importance of a multi-domain approach to effectively identify adverse non-motor outcomes after stroke to inform the development of more holistic patient care pathways after stroke.

Combined Effect of Early Physical Exercise and Stereotactic Hematoma Evacuation in Patients with Cerebral Hemorrhage Undergoing Hemodialysis.

Objective: This study investigated the combined effect of stereotactic hematoma evacuation and early postoperative physical function exercise in hemodialysis patients with cerebral hemorrhage. Methods: A retrospective study was conducted, including a total of 78 hemodialysis patients with cerebral hemorrhage treated at our hospital between January 2021 and June 2022. The patients were equally allocated to two groups based on different postoperative rehabilitation methods. The control group underwent stereotactic hematoma evacuation, while the study group received additional early postoperative physical function exercise in addition to the intervention provided to the control group. The operative conditions of both groups were recorded, and comparisons were made concerning neural function, limb function, daily activity ability, and complications. Results: There were no significant differences between the two groups regarding operation time, intraoperative blood loss, and hematoma removal rate (P > .05). However, the study group demonstrated a significantly shorter hospital stay (12.98 ± 2.01 days) compared to the control group (15.02 ± 2.07 days), P < .05. Post-treatment, the study group exhibited substantially lower neurological function scores (NIHSS score) (6.37 ± 1.02) compared to the control group (10.03 ± 1.09), P < .05. Additionally, the study group showed significantly higher limb function scores (P < .05) and daily activity ability scores (P < .05) compared to the control group. Moreover, the incidence of complications in the study group was significantly lower than that in the control group (P < .05). Conclusions: Early postoperative physical function exercise following stereotactic hematoma evacuation showed beneficial effects in hemodialysis patients with cerebral hemorrhage. It effectively reduced operation time, restored nerve and limb function, improved daily activity ability, and reduced the incidence of related complications. These approaches hold crucial clinical significance.

Effects of Conventional Speech Therapy with Liuzijue Qigong, a Traditional Chinese Method of Breath Training, in 70 Patients with Post-Stroke Spastic Dysarthria.

BACKGROUND Post-stroke spastic dysarthria (PSSD) is a motor speech impairment that impacts patient communication and quality of life. Liuzijue Qigong (LQG), a traditional Chinese method of breath training, could serve as an effective treatment for PSSD. This study compared the effects of conventional speech therapy and conventional speech therapy combined with LQG in patients with PSSD. MATERIAL AND METHODS Seventy patients with PSSD were randomly divided into a control group (conventional speech therapy, n=35, 77.14% cerebral infarction, 22.86% cerebral hemorrhage) and experimental group (LQG combined with conventional speech therapy, n=35, 85.71% cerebral infarction, 14.29% cerebral hemorrhage). Conventional speech therapy included relaxation, breath control, organ articulation, and pronunciation training. LQG involved producing 6 different sounds (Xu, He, Hu, Si, Chui, and Xi) accompanied by breathing and body movements. Patients were treated once a day, 5 times a week, for 4 weeks. The Frenchay Dysarthria Assessment scale (FDA), speech articulation, maximum phonation time (MPT), loudness, and Montreal Cognitive Assessment scale (MoCA) were evaluated. RESULTS At 4 weeks, the experimental group showed significant improvements compared with the control group in the change of FDA (13.26±6.84 vs 18.03±5.32, P=0.028), speech articulation (63.17±22.40 vs 76.51±15.28, P=0.024), MPT (1.34±1.30 vs 3.89±3.98, P<0.001), loudness (3.46±2.74 vs 7.14±2.56, P=0.009), MoCA (19.40±3.72 vs 22.20±5.30, P=0.020), total effective rate (68.57% vs 88.57%, P=0.041). CONCLUSIONS LQG, when combined with conventional speech therapy, enhanced the comprehensive speech ability of patients with PSSD compared with conventional treatment alone.

Combination of single-nucleus and bulk RNA-seq reveals the molecular mechanism of thalamus haemorrhage-induced central poststroke pain.

Central poststroke pain (CPSP) induced by thalamic haemorrhage (TH) can be continuous or intermittent and is accompanied by paresthesia, which seriously affects patient quality of life. Advanced insights into CPSP mechanisms and therapeutic strategies require a deeper understanding of the molecular processes of the thalamus. Here, using single-nucleus RNA sequencing (snRNA-seq), we sequenced the transcriptomes of 32332 brain cells, which revealed a total of four major cell types within the four thalamic samples from mice. Compared with the control group, the experimental group possessed the higher sensitivity to mechanical, thermal, and cold stimuli, and increased microglia numbers and decreased neuron numbers. We analysed a collection of differentially expressed genes and neuronal marker genes obtained from bulk RNA sequencing (bulk RNA-seq) data and found that Apoe, Abca1, and Hexb were key genes verified by immunofluorescence (IF). Immune infiltration analysis found that these key genes were closely related to macrophages, T cells, related chemokines, immune stimulators and receptors. Gene Ontology (GO) enrichment analysis also showed that the key genes were enriched in biological processes such as protein export from nucleus and protein sumoylation. In summary, using large-scale snRNA-seq, we have defined the transcriptional and cellular diversity in the brain after TH. Our identification of discrete cell types and differentially expressed genes within the thalamus can facilitate the development of new CPSP therapeutics.

Association of Cerebrospinal Fluid Biomarkers with Submental and Cerebral Hemorrhage: A Case-Control Study.

Objective: This retrospective case-control study aimed to investigate the relationship between cerebrospinal fluid (CSF) biomarkers and subarachnoid hemorrhage (SAH) and cerebral hemorrhage (CH) and to determine whether these biomarkers can predict the risk of hemorrhage. Methods: Patients diagnosed with SAH and CH at Chongqing University Central Hospital between January 2020 and April 2022 were included in this study. CSF-adenosine deaminase (ADA), CSF-lactate (Lac), and CSF-lactate dehydrogenase (LDH) were measured, and their associations with hemorrhage risk were analyzed using multivariable logistic regression models. The predictive value of these biomarkers was evaluated using receiver operating characteristic (ROC) analysis. Results: A total of 114 SAH patients, 105 CH patients, and 53 healthy controls were included in this study. The multivariable analysis revealed that hypertension, CSF-ADA, and CSF-Lac were independent risk factors for SAH, while hypertension and CSF-LDH were independent risk factors for CH. The ROC analysis demonstrated that the combination of CSF-ADA and CSF-Lac had the highest predictive value for SAH (area under the curve = 0.938), while CSF-LDH had the highest predictive value for CH (area under the curve = 0.946). Conclusion: CSF biomarkers, specifically CSF-ADA, CSF-Lac, and CSF-LDH, are valuable predictors of SAH and CH. These biomarkers may assist in diagnosing and managing hemorrhagic stroke in clinical settings.

Impact of Vitamin D3 on Carbonyl-Oxidative Stress and Matrix Metalloproteinases after Acute Intracerebral Hemorrhage in Rats with Type 2 Diabetes Mellitus.

INTRODUCTION: Diabetes mellitus is associated with the development of carbonyl-oxidative stress (COS) and an increased risk of a cerebral hemorrhage. Vitamin D3 is considered an additional drug to have an impact on COS and proteolysis in the extracellular matrix. OBJECTIVE: The study aimed to evaluate the impact of D3 on the COS-markers and matrix metalloproteinases MMP2/MMP9 activity after acute intracerebral hemorrhage (ICH) in rats with experimental type 2 diabetes mellitus (Т2DM) compared to metformin (Met). METHODS: T2DM was induced in rats via the intraperitoneal injection of streptozotocin (STZ) and nicotinamide (NA), ICH - by microinjection of bacterial collagenase into the striatum. Rats were randomized into five groups: 1 - intact animals (n = 8), 2 - T2DM (n = 9); 3 - T2DM+ICH (n = 7); 4 - T2DM+ICH+Met (n = 7); 5 - T2DM+ICH+D3 (n = 7). Blood glucose, glycated hemoglobin, and oral glucose tolerance test (OGTT) were assessed using commercial kits. Advanced oxidation protein products (AOPP), protein carbonyls (PC370/430), and ischemia-modified albumin (IMA) were measured by spectrophotometry, advanced glycation end products (AGEs) by quantitative fluorescence, and matrix metalloproteinases MMP2/9 by gelatin zymography. RESULTS: D3 does not significantly affect the glucose level and OGTT in rats with T2DM+ICH. However, it reduces AOPP, PC, and AGEs, thus reducing the COS index. In contrast, the activity of proMMP9 increases after D3 administration. These effects of D3 have been reported to be stronger and sometimes opposite to those of metformin. CONCLUSION: D3 supplementation may decrease the negative consequences of a cerebral hemorrhage in T2DM by reducing COS and preventing the accumulation of COS-modified proteins in the brain by regulating the expression and activity of MMP9.

Incidence and risk factors associated with progression to mild cognitive impairment among middle aged and older adults.

OBJECTIVE: We performed this longitudinal 2-year follow-up study to determine the incidence and risk factors associated with MCI in middle-aged and older adults. SUBJECTS AND METHODS: This community-based longitudinal study was conducted in adults aged ≥ 50 years with normal cognitive function in Shanghai community, China, over a period of two years. Information about the socio-demographic, behavioral, anthropometric, and biochemical parameters was obtained at the baseline and cognitive function was assessed at the end of the follow-up period using the Montreal cognitive assessment tool. RESULTS: A total of 985 participants aged ≥ 50 years were included in the analysis. Incidence of MCI during the 2-year follow-up period among the study participants was 26.7% (95% CI: 24.0%-29.6%). Participants with lower level of education [primary - adjusted RR=2.79 (95% CI: 1.38-5.64 and secondary - adjusted RR=1.62 (95% CI: 1.17-2.24)], with history of cerebral infarction (adjusted RR=1.49; 95% CI: 1.05-2.12), history of cerebral hemorrhage (adjusted RR=3.20; 95% CI: 1.22-8.40) were found to have significantly higher risk of MCI. Regular tea consumption was associated with significantly reduced risk of MCI development (adjusted RR=0.69; 95% CI: 0.49-0.96). CONCLUSIONS: Our study found that one in four participants developed MCI during the 2-year follow-up period. Lower educational level, history of cerebral infarction, cerebral hemorrhage and tea consumption were significant determinants of MCI incidence. The target groups identified in this study should be closely monitored with regular follow-up investigations for early diagnosis and appropriate management of the condition.

Naoxintong Capsule for Secondary Prevention of Ischemic Stroke: A Multicenter, Randomized, and Placebo-Controlled Trial.

OBJECTIVE: To examine whether the combination of Naoxintong Capsule with standard care could further reduce the recurrence of ischemic stroke without increasing the risk of severe bleeding. METHODS: A total of 23 Chinese medical centers participated in this trial. Adult patients with a history of ischemic stroke were randomly assigned in a 1:1 ratio using a block design to receive either Naoxintong Capsule (1.2 g orally, twice a day) or placebo in addition to standard care. The primary endpoint was recurrence of ischemic stroke within 2 years. Secondary outcomes included myocardial infarction, death due to recurrent ischemic stroke, and all-cause mortality. The safety of drugs was monitored. Results were analyzed using the intention-to-treat principle. RESULTS: A total of 2,200 patients were enrolled from March 2015 to March 2016, of whom 143 and 158 in the Naoxintong and placebo groups were lost to follow-up, respectively. Compared with the placebo group, the recurrence rate of ischemic stroke within 2 years was significantly lower in the Naoxintong group [6.5% vs. 9.5%, hazard ratio (HR): 0.665, 95% confidence interval (CI): 0.492-0.899, P=0.008]. The two groups showed no significant differences in the secondary outcomes and safety, including rates of severe hemorrhage, cerebral hemorrhage and subarachnoid hemorrhage (P>0.05). CONCLUSION: The combination of Naoxintong Capsule with standard care reduced the 2-year stroke recurrence rate in patients with ischemic stroke without increasing the risk of severe hemorrhage in high-risk patients.

Molecular, Pathological, Clinical, and Therapeutic Aspects of Perihematomal Edema in Different Stages of Intracerebral Hemorrhage.

Acute intracerebral hemorrhage (ICH) is a devastating type of stroke worldwide. Neuronal destruction involved in the brain damage process caused by ICH includes a primary injury formed by the mass effect of the hematoma and a secondary injury induced by the degradation products of a blood clot. Additionally, factors in the coagulation cascade and complement activation process also contribute to secondary brain injury by promoting the disruption of the blood-brain barrier and neuronal cell degeneration by enhancing the inflammatory response, oxidative stress, etc. Although treatment options for direct damage are limited, various strategies have been proposed to treat secondary injury post-ICH. Perihematomal edema (PHE) is a potential surrogate marker for secondary injury and may contribute to poor outcomes after ICH. Therefore, it is essential to investigate the underlying pathological mechanism, evolution, and potential therapeutic strategies to treat PHE. Here, we review the pathophysiology and imaging characteristics of PHE at different stages after acute ICH. As illustrated in preclinical and clinical studies, we discussed the merits and limitations of varying PHE quantification protocols, including absolute PHE volume, relative PHE volume, and extension distance calculated with images and other techniques. Importantly, this review summarizes the factors that affect PHE by focusing on traditional variables, the cerebral venous drainage system, and the brain lymphatic drainage system. Finally, to facilitate translational research, we analyze why the relationship between PHE and the functional outcome of ICH is currently controversial. We also emphasize promising therapeutic approaches that modulate multiple targets to alleviate PHE and promote neurologic recovery after acute ICH.

Effect of hypophosphatemia on prognosis after spontaneous intracerebral hemorrhage: a retrospective study.

OBJECTIVE: Hypophosphatemia often occurs after spontaneous intracerebral hemorrhage, but the effect of hypophosphatemia on its prognosis is under debate. METHODS: Clinical data of patients with spontaneous intracerebral hemorrhage admitted to our neurosurgery department from January 2018 to June 2020 were retrospectively analyzed. The patients were divided into the hypophosphatemia group and the nonhypophosphatemia group according to the serum phosphorus test values obtained three times within 1 week after admission. The incidence of complications during hospitalization, 28-day mortality, and 6-month mRS score were compared between the two groups. The influence of low phosphorus in patients with hypophosphatemia on the 6-month mRS score was explored. RESULTS: A total of 133 patients were included, of which 85 had hypophosphatemia. Forty-two patients (21 in the hypophosphatemia group and 21 in the nonhypophosphatemia group) were enrolled after propensity score matching. There were no statistically significant differences in the incidence of complications during hospitalization, 28-day mortality, and 6-month mRS score between the two groups (P > 0.05). In 85 patients with hypophosphatemia, the minimum serum phosphorus was associated with the 6-month mRS score (B = - 3.153, 95% CI: - 5.842 ~ - 0.463, P = 0.022). The cutoff value of serumphosphorus for predicting 6-month mRS score was 0.505 mmol/l. CONCLUSION: Whether hypophosphatemia occurred during hospitalization in patients with spontaneous intracerebral hemorrhage showed no effect on the incidence of complications, 28-day mortality, and 6-month mRS score. A significant decrease in serum phosphorus during hospitalization (≤ 0.505 mmol/l) might correlate with a poor 6-month mRS score. Maintaining serum phosphorus stability after spontaneous intracerebral hemorrhage may improve prognosis.

[Fecal microbiota transplantation in the treatment of acute intestinal pseudo obstruction secondary to intracerebral hemorrhage: a case report and literature review].

OBJECTIVE: To analyze the clinical effects of fecal microbiota transplantation (FMT) on the treatment of acute intestinal pseudo obstruction (AIPO) secondary to intracerebral hemorrhage. METHODS: The clinical data of a patient with AIPO secondary to intracerebral hemorrhage who was admitted to Nanfang Hospital of Southern Medical University was analyzed. The flora compositon between donor and patient was compared, finding the changes of intestinal flora before and after FMT (day 0 and day 25). RESULTS: The main clinical findings in the patient were serious bloating, expansion of the intestinal canal and intra-abdominal hypertension. A week of conventional therapy was not effective, and the symptoms became progressively worse, affecting respiratory function.The result of fecal flora suggested the intestinal microbiota dybiosis, so FMT was attempted. After FMT, the patient's gastrointestinal symptoms were significantly relieved, and there were no further episodes within 25 days. The new result of fecal flora showed that the flora colonizing the intestine was dominated by Akkermansia and Bifidobacterium, with a significant decrease in potential pro-inflammatory and gas-producing bacteria and an increased gut microbiota diversity. The results trended to be partly consistent with the donor at 25 days after FMT: at the phylum level, the relative abundance of Bacterioidetes, Vereucomicrobia, Firmicutes and Actinobacteria were increased while Proteobacteria was decreased; at the class level, the relative abundance of Verrucomicrobiae, Bacterioidia, Actinobacteria, Coriobacteriia and Clostridia were increased and Gammaproteobacteria was decreased; at the order level, the relative abundance of Bacterioidales, Verrucomicrobiales, Clostridiale, Coriobacteriales were increased and Betaproteobacteriales, Enterobacteriales were decreased; at the family level, the relative abundance of Bifidobacteriaceae, Akkermansiaceae, Ruminococcaceae were increased and Enterobacteriaceae was decreased; at the genus level, the relative abundance of Akkermansia, Bifidobacterium were increased and Escherichia-Shigella, Klebsiella were decreased. At 1-year follow-up, the patient lived with self-care and scored 5 points in Glasgow outcome scale (GOS). CONCLUSIONS: FMT may provide clinical benefit in treated patients with AIPO secondary to intracerebral hemorrhage, probably by regulating the intestinal microflora, and re-establishing proper intestinal barrier, to maintain intestinal homeostasis.

The Influence of Select Medications on Prospective Hemorrhage Risk in Patients with Spinal or Cerebral Cavernous Malformations.

BACKGROUND: Effects of select medications on hemorrhage risk in patients with cerebral or spinal cavernous malformations (CMs) are unknown. METHODS: From a single-institution prospective cohort of patients with CM (2015-2021), demographics, mode of clinical presentation, and radiographic data were collected. Follow-up was performed with electronic medical record review, in-person visits, and written surveys. Select medication use was ascertained from the time of CM diagnosis to a censor date of first prospective symptomatic hemorrhage, complete surgical excision of sporadic form CM, last follow-up, or death. Using Cox proportional hazards regression model, we assessed effects of antithrombotic agents, fish oil, selective serotonin reuptake inhibitors (SSRIs), vitamin E and D supplementation, statins, and beta blockers on prospective hemorrhage risk. RESULTS: The study included 364 patients with spinal or cerebral CM (58.0% female; 20.0% familial form; 42.3% presentation to medical attention owing to hemorrhage; 25.8% brainstem location). During a follow-up of 2018 patient-years, 103 prospective hemorrhages occurred. No studied medications increased the prospective CM hemorrhage risk. Antithrombotics, vitamin D supplementation, fish oil, and SSRI were associated with lower hemorrhage risk even after adjusting for age at diagnosis, hemorrhage at diagnosis, and brainstem location. CONCLUSIONS: Use of select medications with antithrombotic properties do not increase the risk of CM hemorrhage. Vitamin D supplementation, any antithrombotic agent, fish oil, and SSRI were associated with a lower prospective hemorrhage risk. Further studies should evaluate the mechanism of action and potential benefit of these select medications.

Diet-Induced High Serum Levels of Trimethylamine-N-oxide Enhance the Cellular Inflammatory Response without Exacerbating Acute Intracerebral Hemorrhage Injury in Mice.

Trimethylamine-N-oxide (TMAO), an intestinal flora metabolite of choline, may aggravate atherosclerosis by inducing a chronic inflammatory response and thereby promoting the occurrence of cerebrovascular diseases. Knowledge about the influence of TMAO-related inflammatory response on the pathological process of acute stroke is limited. This study was designed to explore the effects of TMAO on neuroinflammation, brain injury severity, and long-term neurologic function in mice with acute intracerebral hemorrhage (ICH). We fed mice with either a regular chow diet or a chow diet supplemented with 1.2% choline pre- and post-ICH. In this study, we measured serum levels of TMAO with ultrahigh-performance liquid chromatography-tandem mass spectrometry at 24 h and 72 h post-ICH. The expression level of P38-mitogen-protein kinase (P38-MAPK), myeloid differentiation factor 88 (MyD88), high-mobility group box1 protein (HMGB1), and interleukin-1ß (IL-1ß) around hematoma was examined by western blotting at 24 h. Microglial and astrocyte activation and neutrophil infiltration were examined at 72 h. The lesion was examined on days 3 and 28. Neurologic deficits were examined for 28 days. A long-term choline diet significantly increased serum levels of TMAO compared with a regular diet at 24 h and 72 h after sham operation or ICH. Choline diet-induced high serum levels of TMAO did not enhance the expression of P38-MAPK, MyD88, HMGB1, or IL-1ß at 24 h. However, it did increase the number of activated microglia and astrocytes around the hematoma at 72 h. Contrary to our expectations, it did not aggravate acute or long-term histologic damage or neurologic deficits after ICH. In summary, choline diet-induced high serum levels of TMAO increased the cellular inflammatory response probably by activating microglia and astrocytes. However, it did not aggravate brain injury or worsen long-term neurologic deficits. Although TMAO might be a potential risk factor for cerebrovascular diseases, this exploratory study did not support that TMAO is a promising target for ICH therapy.

Efficacy of Naoxueshu in acute spontaneous intracerebral hemorrhage: a multicenter observational study.

OBJECTIVE: To evaluate the efficacy and safety outcome and related risk factors of Naoxueshu in the treatment of acute SICH. METHODS: Two hundred twenty patients were enrolled in this study. Diagnosis of SICH was based on neuroimaging. All the patients received regular treatment and Naoxueshu oral liquid 10 ml 3 times a day for 14 consecutive days. Surgical intervention was conducted as needed. Efficacy and safety outcomes were evaluated. RESULTS: Hematoma volume decreased significantly 7 days after Naoxueshu treatment (from 27.3 ± 20.0 to 15.1 ± 15.1 ml, P < 0.0001), and it decreased further in 14-day result (6.9 ± 10.4 ml, P < 0.0001). Patients' neurological function was improved remarkably with NIHSS scores from baseline 13 points to 7-day 7 points (P < 0.0001) and 14-day 4 points (P < 0.0001). Cerebral edema was relieved only 14 days after Naoxueshu treatment (from 3 to 2 points, P < 0.0001). No clinically significant change was found in 7-day and 14-day safety results. Female sex was related independently to large 7-day hematoma volume and worse 7-day NIHSS score while it would not affect patients' 14-day outcomes. Rare cause of SICH (B = 17.4, P = 0.009) alone was related to large 14-day hematoma volume. Worse baseline NIHSS score (B = 0.3, P = 0.003) and early use of Naoxueshu (B = 2.9, P = 0.005) were related to worse 7-day and14-day neurological function. CONCLUSION: Naoxueshu oral liquid could relieve hematoma volume and cerebral edema safely; meanwhile, it could improve patients' neurological function. Sex, cause of SICH, and time from onset to receive Naoxueshu should be taken into consideration in the treatment of SICH.

Different Effects of Hematoma Expansion on Short-Term Functional Outcome in Basal Ganglia and Thalamic Hemorrhages.

PURPOSE: To investigate the impact of hematoma expansion (HE) on short-term functional outcome of patients with thalamic and basal ganglia intracerebral hemorrhage. METHODS: Data of 420 patients with deep intracerebral hemorrhage (ICH) that received a baseline CT scan within 6 hours from symptom onset and a follow-up CT scan within 72 hours were retrospectively analyzed. The poor functional outcome was defined as modified Rankin score (mRS) > 3 at 30 days. Receiver operating characteristic (ROC) curves for relative and absolute growth of HE were generated and compared. Multivariable logistic regression models were used to analyze the impact of HE on the functional outcome in basal ganglia and thalamic hemorrhages. The predictive values for different thresholds of HE were calculated, and correlation coefficient matrices were used to explore the correlation between the covariables. RESULTS: Basal ganglia ICH showed a higher possibility of absolute hematoma growth than thalamic ICH. The area under the curve (AUC) for absolute and relative growth of thalamic hemorrhage was lower than that of basal ganglia hemorrhage (AUC 0.71 and 0.67, respectively) in discriminating short-term poor outcome with an AUC of 0.59 and 0.60, respectively. Each threshold of HE independently predicted poor outcome in basal ganglia ICH (P < 0.001), with HE > 3 ml and > 6 ml showing higher positive predictive values and accuracy compared to HE > 33%. In contrast, thalamic ICH had a smaller baseline volume (BV, 9.55 ± 6.85 ml) and was more likely to initially involve the posterior limb of internal capsule (PLIC) (85/153, 57.82%), and the risk of HE was lower without PLIC involvement (4.76%, P = 0.009). Therefore, in multivariate analysis, the effect of thalamic HE on poor prognosis was largely replaced by BV and the involvement of PLIC, and the adjusted odds ratios (ORs) of HE was not significant (P > 0.05). CONCLUSION: Though HE is a high-risk factor for short-term poor functional outcome, it is not an independent risk factor in thalamic ICH, and absolute growth is more predictive of poor outcome than relative growth for basal ganglia ICH.

Ginsenoside Rg2 Ameliorates Brain Injury After Intracerebral Hemorrhage in a Rat Model of Preeclampsia.

The incidence of maternal hemorrhagic stroke is elevated in women with preeclampsia during pregnancy. Panax ginseng is a traditional medicinal herb with numerous applications, and ginsenosides are the key bioactive compounds in Panax ginseng. This study aims to evaluate the effects of ginsenoside Rg2 on pregnancy outcomes and brain injury after intracerebral hemorrhage (ICH) in a rat model of preeclampsia. Preeclampsia was induced in rats by N(ω)-nitro-L-arginine methyl ester. Then, an ICH model was prepared by intrastriatal injection of bacterial collagenase. Ginsenoside Rg2 markedly elevated the survival ratio of fetuses. The placental and body weights were increased in the ginsenoside Rg2 group. Compared with the preeclampsia group, the Garcia test score of ginsenoside Rg2-treated rats was significantly increased. Ginsenoside Rg2 treatment ameliorated the ICH-induced augmentation of Evans blue extravasation, inhibited the ICH-induced elevation of brain water content, and reduced the interleukin-1ß and tumor necrosis factor-α levels in the hemorrhagic hemisphere after ICH in preeclampsia model rats. Furthermore, ginsenoside Rg2 treatment not only inhibited augmentation of TLR-4, MyD88, p-IκBα, and p-NF-κB expression but also abated the reduction of occludin and claudin-5 expression in the hemorrhagic hemisphere. The findings indicated that ginsenoside Rg2 improved pregnancy outcomes in a rat model of preeclampsia without decreasing the blood pressure and urine protein level. The findings also demonstrated that ginsenoside Rg2 ameliorated ICH-induced neurological disorder and blood-brain barrier dysfunction in an animal model of preeclampsia by regulating the TLR4/NF-κB signaling pathway.

Using Electronic Medical Records of Nursing Care to Characterize Constipation in Patients with Intracerebral Hemorrhage.

INTRODUCTION: Constipation is one of the common poststroke complications that directly affect the patients' quality of life in patients with intracerebral hemorrhage (ICH), which has not been paid enough attention. OBJECTIVE: This study investigates constipation's clinical characteristics and its risk factors in ICH patients driven by the electronic medical records of nursing care. METHODS: This retrospective chart review investigated patients with acute spontaneous ICH admitted at a tertiary care center from October 2010 to December 2018. Poststroke constipation was defined as a first stool passage occurring after 3 days postadmission and the use of enemas or laxatives after ICH. The associations between constipation present and potential factors were evaluated. RESULTS: Of 1,748 patients, 408 (70.3% men, mean age 58 ± 14 years) patients with poststroke constipation were identified. After adjusting for potential confounding variables, the risk factors independently associated with poststroke constipation are admission Glasgow Coma Scale score (odds ratio [OR] 0.62, 95% confidence interval [CI] 0.44-0.88; p = 0.007), use of mechanical ventilation (OR 3.74, 95% CI 2.37-5.89, p < 0.001), enteral nutrition (OR 2.82, 95% CI 1.85-4.30, p < 0.001), hematoma evacuation (OR 2.10, 95% CI 1.40-3.16; p < 0.001), opioid analgesics (OR 1.86, 95% CI 1.32-2.62; p < 0.001), sedation (OR 1.83, 95% CI 1.20-2.77; p = 0.005), and vasopressors (OR 1.81, 95% CI 1.26-2.61; p = 0.001) in order. Similar associations were observed in the prespecified length of the stay subgroup. Patients with constipation were associated with a longer hospital stay length (2.24 days, 95% CI 1.43-3.05, p < 0.001) but not with in-hospital mortality (OR 1.05, 95% CI 0.58-1.90, p = 0.871). CONCLUSIONS: Our findings suggested that risk factors influence the absence of constipation after ICH with the synergy of different weights. The occurrence of constipation likely affects a longer length of stay, but not in-hospital mortality. Future prospective investigations are warranted to validate our findings and identify the optimal management of constipation that may improve the quality of life in patients with ICH.

Efficacy of Sanqi (Radix Notoginseng) in treating cerebral hemorrhage in rats with traumatic brain injury.

OBJECTIVE: To evaluate the protective efficacy of Sanqi (Radix Notoginseng) on cerebral hemorrhage in a rat model of traumatic brain injury (TBI) by investigating plasminogen activator inhibitor-1 (PAI-1), tissue-type plasminogen activator (t-PA), nuclear factor-κB (NF-κB, p-p65), nitric oxide (NO), endothelin (ET), cluster differentiation (CD61CD62), and coagulation. METHODS: The free-fall method was used to create a rat model of TBI. Forty-eight rats were randomly divided into six groups: the blank group, sham group, model group, low-dose Sanqi (Radix Notoginseng) group, middle-dose Sanqi (Radix Notoginseng) group, and high-dose Sanqi (Radix Notoginseng) group. At 24 h after the model was created, we investigated brain MRI, brain tissue morphology using HE staining, flow cytometry, and immunohistochemical changes. RESULTS: Cerebral hemorrhage was aggravated in TBI rats (observed in brain specimens, brain MRI, and brain tissue HE). Cerebral immunohistochemistry results demonstrated that the expression of t-PA, PAI-1 and p-p65 increased significantly in TBI rats, while t-PA/PAI-1 had a significant decrease. In addition, CD61CD62, D2D, and ET were significantly increased in TBI rats, and PT and APTT were significantly prolonged; in contrast, NO was significantly decreased. Sanqi (Radix Notoginseng) decreased cerebral hemorrhage in TBI rats (observed in brain MRI and brain tissue HE), and increased t-PA/PAI-1, CD61CD62 significantly. It also significantly decreased the expression of t-PA, PAI-1, and p-p65 in brain immunohistochemistry and significantly decreased PT, APTT, D2D, and ET. However, there were no differences in NO between the model group and the Sanqi (Radix Notoginseng) group. CONCLUSION: Sanqi (Radix Notoginseng) can decrease the expression of p-p65, increase t-PA/PAI-1, and stem traumatic intracranial hemorrhage in a TBI rat model.
