Carotid plaques and neurological impairment in patients with acute cerebral infarction.

ABSTRACT: OBJECTIVE:To determine whether the coexistence of carotid atherosclerosis plaque affects the neurological function of cerebral infarction. METHODS:A total of 1078 patients with acute cerebral infarction were enrolled, all patients were divided into carotid plaque group (n = 702) and non-carotid plaque group (n = 376). Meanwhile, all patients were divided into mild group (n = 624) and moderate to severe group (n = 454). The difference of the incidence of carotid plaque between the mild and moderate to severe group was analyzed. RESULTS:In the 1078 patients with cerebral infarction, the NIHSS score in the carotid plaque group was significantly higher than that in the non-carotid plaque group (P<0.05). The number of mild cases without carotid artery plaque group was larger than that of plaque group (P<0.05), and the number of moderate to severe cases in carotid plaque group was larger than that in non-plaque group (P<0.05). In patients with carotid atherosclerotic plaque, the risk of moderate to severe cerebral infarction was 2.11 times higher than that without carotid artery plaque. Lastly, patients with single plaques were 1.82 times more likely to develop moderate to severe cerebral infarction than those without carotid plaque, while patients with multiple carotid plaques were 2.41 times higher to get moderate or severe cerebral infarction than those without carotid plaque. CONCLUSIONS:The incidence of carotid atherosclerotic plaques may be related to neurological deficits in patients with acute cerebral infarction.

Project description:IntroductionThere is little evidence about the factors related to the detection of neurological deterioration by nurses. We examined the related factors and therapeutic outcomes of nurses' detections of patient's neurological deterioration.MethodsThis was a descriptive retrospective study. We included 549 adult stroke patients who were admitted to the acute stroke unit of a tertiary hospital between May 2018 and December 2019 and had changes in neurological symptoms that were detected by stroke nurses. We measured the following outcomes: stroke lesion progression, early neurological deterioration (increase in the total national institutes of health stroke scale score of 2 points or more, increase in the limb weakness score of 1 point or more, or decrease in the alertness score of 1 point or more), and additional clinical management (increasing intravenous fluids, diagnostic imaging, or neuro-intervention). Data was analyzed by logistic regression.ResultsA total of 651 new or aggravating symptoms were detected by nurses. The most detected symptom was motor aggravations (49.2 %). Symptoms were commonly detected during the day shift (51.0 %) and by scheduled neurochecks (71.3 %). Of 132 patients who underwent diagnostic imaging by nurses' detection, 63.6 % cases had stroke lesion progression. Nursing experience over 4 years was positively associated with finding stroke lesion progression (OR: 2.49, 95 % CI = 1.09-5.67). Early neurological deterioration was found in 70.7 %, and it was significantly higher during scheduled neurochecks (OR:2.65, 95 % CI = 1.04-6.72) and in the group of large artery atherosclerosis (OR: 2.19, 95 % CI = 1.06-4.49) Additional clinical management was provided to 49.9 % of detection, and scheduled neurocheks (OR: 4.76, 95 % CI = 2.18-10.39) and changes of alertness (OR: 2.89, 96 % CI = 1.51-5.26) were the significant factors.ConclusionStroke nurses were able to detect a large number of stroke lesion progression and early neurological deterioration as well as to provide additional clinical management. Systematic guidelines for qualification of stroke nurses may be beneficial.

Project description:IntroductionThis prospective observational study with a control group aimed to compare the plasma levels of long non-coding RNA (lncRNA) LIPCAR between patients with acute cerebral infarction (ACI) and healthy controls, and to assess the prognostic abilities of LIPCAR for adverse outcomes of patients with ACI at 1-year follow-up.MethodsEighty patients with ACI, of whom 40 had large artery atherosclerosis (LAA) and 40 had cardioembolism (CE) and who were hospitalized at Xi'an No. 1 Hospital from July 2019 to June 2020, were selected as the case group. Age- and sex-matched non-stroke patients from the same hospital throughout the same time period were chosen as the control group. Real-time quantitative reverse transcription polymerase chain reaction was used to measure the levels of plasma lncRNA LIPCAR. The correlations of LIPCAR expression among the LAA, CE, and control groups were assessed using Spearman's correlation analysis. Curve fitting and multivariate logistic regression were used to analyze the LIPCAR levels and 1-year adverse outcomes of patients with ACI and its subtypes.ResultsThe expression of plasma LIPCAR in the case group was noticeably higher than that of the control group (2.42 ± 1.49 vs. 1.00 ± 0.47, p < 0.001). Patients with CE had considerably higher levels of LIPCAR expression than those with LAA. The National Institute of Health Stroke Scale score and modified Rankin scale score on admission were significantly positively correlated with LIPCAR expression in patients with CE and LAA. Furthermore, the correlation was stronger in patients with CE than in those with LAA, with correlation coefficients of 0.69 and 0.64, respectively. Curve fitting revealed a non-linear correlation between LIPCAR expression levels, 1-year recurrent stroke, all-cause mortalities, and poor prognoses, with a cut-off value of 2.2.ConclusionThe expression level of lncRNA LIPCAR may play a potential role in the identification of neurological impairment and CE subtype in patients with ACI. Increased 1-year risk of adverse outcomes may be associated with high levels of LIPCAR expression.

Project description:Background and aimsRecent evidence suggest that microbiota is associated with almost all major types of diseases, including cardiovascular diseases. However, its role in Acute Cerebral Infarction remains unexplored. It is important to understand the diversity and distribution of gut microbiota (GM) in patients with Acute Cerebral Infarction and the role that GM plays in this type of disease.MethodsWe performed pyrosequencing on the gut microbiota of 40 individuals in order to elucidate whether the composition of the microbiota differs between patients with Acute Cerebral Infarction and healthy controls: Of these individuals, there were 31 with Acute Cerebral Infarction and nine controls. We applied linear regression to calculate the correlation between the gut flora and disease risk factors. Finally, KEGG functional enrichment analysis was conducted to examine the correlation between the gut flora and Acute Cerebral Infarction.ResultsThe overall microbial structure was similar in both the controls and the patients, but the control group had higher relative presence of Blautia obeum while the presence of Streptococcus infantis and Prevotella copri were relatively higher in the patient group. Using linear regression, we found that Blautia obeum was negatively associated with white blood cell count and Streptococcus infantis was positively correlated with creatinine and lipoprotein. The KEGG pathway analysis indicated that the bio-pathways including methane metabolism, lipopolysaccharide synthesis, bacterial secretion, and flagellar assembly of the gut microbiota in the patient group was expressed differently than that of the controls. We identified three differentially expressed gut microbial functions in Acute Cerebral Infarction and found four bacterial pathways that might be related to the development of this disease.ConclusionsOur study identified three abnormally-expressed bacteria-Blautia obeum, Streptococcus infantis, and Prevotella copri-in patients with Acute Cerebral Infarction compared with healthy controls. It reveals a correlation of these bacterial species with Acute Cerebral Infarction as they relate to disease factors and functional pathways. These findings may shed light on the treatment of cerebral infarction because gut microbiota could serve as a potential therapeutic approach for the treatment of cardiovascular and metabolic diseases.
