BACKGROUND:There is a paucity of outcomes data in patients over 80 years presenting with intracerebral hemorrhage (ICH). The primary aim of our study is to describe outcomes in this patient population. METHOD:Retrospective study of patients admitted with primary ICH from January 2012 to July 2018. Data were obtained from the Rush University Get With The Guidelines database; only patients 80 or above were included. RESULTS:A total of 1713 patients were screened and 220 patients met inclusion criteria. About 68.2% were female and mean age was 85.6 years old. Median ICH score on admission was 2 (IQR 1-3). Location of ICH included: deep (48.2%), lobar (40%), and cerebellum (9.5%). ICH etiologies included hypertensive (51.8%), cerebral amyloid angiopathy (26.8%), coagulopathy (5.9%), and the remaining were undetermined. CT angiograms were performed in 34.5% (n = 76) of patients; of these patients one arteriovenous malformation was identified. Patients underwent the following procedures: external ventricular drains (8.6%), decompression (3.6%), and ventriculoperitoneal shunts (1.8%). Tracheostomy and percutaneous gastrostomy placement were performed in 8.2%. About 4.5% had seizures and 1.5% were treated for status epilepticus. Disposition at hospital discharge included: subacute nursing facility ([SNF] 24.1%), acute rehabilitation (23.2%), hospice (18.2%), death (18.2%), home (11.8%), long-term acute care facility ([LTAC] 3.6%), and unknown (1%). Patients with an ICH score ≥2 on admission had a roughly 6 times higher chance of experiencing an unfavorable outcome (LTAC, SNF, or death), when compared to patients with lower ICH score. CONCLUSIONS:This study shows that a significant proportion (35%) of ICH patients ≥80 years old have a good outcome, with discharge to home or to rehabilitation. Our data suggest that older patients with ICH presenting with supratentorial hemorrhages (volume < 30 cc) without intraventricular extension can have good outcomes despite their age.
背景: 80 岁以上脑出血 (ICH) 患者的结局数据很少。我们研究的主要目的是描述该患者人群的结局。 方法: 对 2012年1月至 2018年7月收治的原发性脑出血患者进行回顾性研究。数据来自 Rush University Get 和指南数据库; 仅纳入 80 例或以上患者。 结果: 共筛选出 1713 例患者，220 例患者符合纳入标准。约 68.2% 为女性，平均年龄为 85.6 岁。入院时 ICH 评分中位数为 2 (IQR 1-3)。ICH 的部位包括: 深部 (48.2%) 、脑叶 (40%) 和小脑 (9.5%)。ICH 病因包括高血压 (51.8%) 、脑淀粉样血管病 (26.8%) 、凝血病 (5.9%)，其余未确定。34.5% (n = 76) 的患者进行了 CT 血管造影; 在这些患者中，发现了一个动静脉畸形。患者接受了以下手术: 脑室外引流 (8.6%) 、减压 (3.6%) 和脑室腹腔分流 (1.8%)。气管切开术和经皮胃造瘘置管术占 8.2%。约 4.5% 有癫痫发作，1.5% 因癫痫持续状态接受治疗。出院时的处置包括: 亚急性护理设施 ([SNF] 24.1%) 、急性康复 (23.2%) 、临终关怀 (18.2%) 、死亡 (18.2%) 、家庭 (11.8%) 、长期急性护理机构 ([LTAC] 3.6%)，未知 (1%)。与 ICH 评分较低的患者相比，入院时 ICH 评分 ≥ 2 分的患者出现不良结局 (LTAC 、 SNF 或死亡) 的机会大约高 6 倍。 结论: 本研究显示，相当大比例 (35%) 的 ≥ 80 岁 ICH 患者有良好的预后，出院回家或康复。我们的数据表明，表现为幕上出血 (体积 <30 cc) 而无脑室扩大的老年 ICH 患者，尽管年龄较大，但预后良好。
METHODS:BACKGROUND:People with stroke are not meeting recommended levels of physical activity. The modifiable factors associated with post-stroke physical activity levels need to be identified to develop targeted interventions. OBJECTIVE:The objective of this study was to investigate the factors at discharge from inpatient rehabilitation that are associated with physical activity levels at 3 months following discharge. DESIGN:This was a prospective cohort study. METHODS:Sixty-four people with stroke completed baseline assessments at discharge from inpatient rehabilitation and 55 completed the follow-up 3 months later. The candidate factors (i.e. gait speed, balance, strength, cognition, mood and motivation) were measured at discharge. The primary outcome measure at follow-up was walking related activity (measured by wrist-worn accelerometer). Secondary outcome measures were physical activity participation (Activity Card Sort) and intensity of physical activity (International Physical Activity Questionnaire - Short 7 days). Adjusted separate multivariable linear regression models or proportional odds regression models were used to evaluate the associations between candidate factors and physical activity. RESULTS:Gait speed and balance were associated with all aspects of physical activity. Higher level of intrinsic motivation was also associated with higher physical activity participation. Anxiety demonstrated a significant non-linear relationship with physical activity participation. LIMITATIONS:Inclusion of fatigue and individual muscle strength could have provided further insights into associations with steps per day. CONCLUSION:The results demonstrated that better physical function at discharge from inpatient rehabilitation was associated with future increased levels of physical activity. Additionally, higher levels of motivation impacted on increased physical activity participation. The influence of anxiety on physical activity participation requires further exploration. Mixed-method study designs can be utilized to further understand the factors associated with post-stroke physical activity.
METHODS:Cerebral ischemia-reperfusion (I/R) is characterized by initial transient cerebral ischemia followed by reperfusion. Various pathophysiological processes are involved in brain injury and functional recovery during cerebral I/R. There are few studies on dynamic metabolic process after cerebral I/R. The present study was to observe dynamic alteration of brain injury, functional recovery, and metabolites after cerebral I/R in rats and discover potential metabolic markers. The cerebral I/R model was established by middle cerebral artery occlusion (MCAO) for 90 min, following reperfusion in rats. The results of cerebral infarction area, cerebral edema, and behavior test showed that there were dynamic changes in brain injury and functional recovery at different periods after cerebral I/R. Further analysis showed that the brain injury was severe on the first day of cerebral I/R, and there was a significant functional recovery from the 7th day of cerebral I/R, followed by an aggravation trend of brain injury from the days 7 to 28. Furthermore, Matrix-assisted laser desorption ionization mass spectrometry imaging analysis showed that the expression of ATP, glucose, and citric acid on 7th day was the highest during cerebral I/R, which indicated that energy metabolism and oxidative phosphorylation played important roles during cerebral I/R. In addition, the untargeted metabolomic results showed that the level of isocitric acid, the ratio of oxyglutaric acid/glutamic acid, and the level of pyruvic acid associated with the TCA cycle were also the highest on the 7th day during cerebral I/R, which indicated that the transient spontaneous recovery of ischemic brain on the 7th day after ischemia-reperfusion might be related to oxidative phosphorylation and energy metabolism in the brain in this period. In conclusion, the results suggest that some small molecule metabolites participate in the brain injury and functional recovery during cerebral I/R, which is of great significance to the development of therapeutic drugs and diagnostic markers.
METHODS:The aims of this study were to study the effects of miR-2 on cerebral ischemia–reperfusion rats and to explore its further mechanism. Rats were assigned into sham, model, miR-22 control and miR-22 groups. Observation of neurological behaviors at 24 h after operation found that neurological functions were severely damaged in the model and miR-22 control groups and these damages were improved by miR-22. RT-PCR indicated that miR-22 mRNA level in the brain tissue was significantly decreased in the model and miR-22 control groups, but increased in the miR-22 group. TTC staining showed increased percentage of cerebral infarction volume in the model and miR-22 control groups and this increase was reduced by miR-22. Immunohistochemistry showed increased densities of CD34^+ and VEGF^+ microvessels in the cortex in the model and miR-22 control groups, which were further increased in the miR-22 group. ELISA showed increased serum VEGF and Ang-1 levels in the model and miR-22 control groups, which were also further increased in the miR-22 group. Western blot analysis showed increased phosphorylation level of PI3K and Akt in brain tissue in the model and miR-22 control groups, which were further increased in the miR-22 group. Administration of LY294002, a specific PI3K pathway inhibitor, significantly reversed all the effects of miR-22 on rats in the model group. miR-22 exerts its neuroprotective and angiogenic functions via the PI3K/Akt signaling pathway, at least partly, in rats under cerebral ischemia–reperfusion.
