RESUMO
Background: Studies indicate a trajectory relationship between baseline blood pressure (BP) and outcome in patients with acute ischemic stroke (AIS) eligible for both intravenous thrombolysis (IVT) with alteplase and endovascular treatment (EVT). We determined whether baseline BP modified the effect of IVT in successfully revascularized AIS patients who participated in the Direct Intra-Arterial Thrombectomy to Revascularize AIS Patients With Large Vessel Occlusion Efficiently in Chinese Tertiary Hospitals (DIECT-MT) trial. Methods: The association of baseline systolic BP, trichotomized as high (141-185 mmHg), middle (121-140 mmHg), and low (91-120 mmHg), and the outcomes of any intracerebral hemorrhage (ICH), symptomatic ICH (sICH), and mortality and functional outcome on the modified Rankin scale at 90 days were explored. Logistic regression models determined the interaction between clinical outcomes and baseline systolic and diastolic BP, and mean arterial pressure (MAP), at 10 mmHg intervals. Data are reported as odds ratios (OR) and 95% CI. Results: A post-hoc analysis of DIRECT-MT, in 510 of the 656 randomized participants with successful revascularization underwent MT. The overall adjusted common OR of IVT and baseline BP on any ICH, sICH, and 90-day mortality and functional outcome were 0.884 (95%CI 0.613-1.274), 0.643 (95%CI 0.283-1.458), 0.842 (95%CI 0.566-1.252), and 1.286 (95%CI 0.772-2.142), respectively. No significant interaction between baseline blood pressure and intravenous thrombolysis with clinical outcome was observed. Conclusions: In patients with baseline SBP under 185 mmHg, baseline blood pressure does not alter the risk of hemorrhagic transformation and clinicaloutcome in successfully revascularized patients, regardless of intravenous alteplase usage. Future studies are needed to confirm our findings. Registration: URL: http://www.clinicaltrials.gov, Identifier: NCT03469206.
RESUMO
Objective:To analyze the correlation between sleep midpoint and sleep quality in insomnia patients with type 2 diabetes mellitus (T2DM).Methods:By adopting current situation investigation research, total of 150 T2DM patients hospitalized in the Department of Endocrinology, the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine from November 2021 to July 2022 were selected as the research objects. The general information questionnaire, Pittsburgh Sleep Quality Index (PSQI), anxiety scale (SAS) and Depression Scale (SDS) were used to investigate, and then analysis the datum.Results:Among 150 T2DM insomnia patients, 41 cases (27.33%) were in the early midpoint sleep group, 37 cases (24.67%) were in the middle midpoint sleep group, and 72 cases (48.00%) were in the late midpoint sleep group. There were significant differences in the distribution of sex, age and BMI level among different sleep midpoint groups ( χ2=7.24, 13.36, 15.93, all P<0.05). The scores of time to fall asleep at the midpoint of sleep in the 3 groups were (2.12 ± 1.25), (2.65 ± 0.79), (2.33 ± 1.02), the difference was significant ( F=2.14, P<0.05); the daytime disability scores in the 3 groups were (1.39 ± 1.36), (2.16 ± 1.12), (1.85 ± 1.32), the difference was significant ( F=3.17, P<0.05). Logistic regression analysis of disorder showed that the time to fall asleep ( OR=4.922, P<0.05) and daytime disability ( OR=4.043, P<0.05) had significant influence to the middle midpoint of sleep group when the early midpoint of sleep group as the control, while the male ( OR=2.182, P<0.05), 50 - 70 years old ( OR=5.005, P<0.05) and BMI over fat side ( OR=3.488, P<0.05) had significant influence to the late midpoint of sleep group. Conclusions:Medical staff should pay attention to the sleep quality of T2DM patients, pay attention to the sleep midpoint of patients, and improve patients′cognition of healthy sleep patterns.
RESUMO
Objective:To evaluate the effect of remote ischemic conditioning (RIC) on left ventricular (LV) myocardial perfusion, myocardial viability, LV remodeling, regional and global LV function serially following acute myocardial infarction (AMI) in Chinese mini-pigs.Methods:AMI was established in 12 Chinese mini-pigs (8 males, 4 females; age: 6-8 months) and they were randomly divided into RIC group ( n=6) and non-RIC group ( n=6). RIC was performed in pigs by blood pressure inflation on the lower limbs for 5 min period and 4 cycles immediately after surgery. A series of myocardial perfusion imaging and gated 18F-fluorodeoxyglucose (FDG) myocardial metabolism PET/CT imaging were performed longitudinally at the 1st, 14th, 28th and 56th days after AMI, and parameters including total perfusion defect (TPD), hibernating myocardium (HM), Scar, left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), summed motion score (SMS), summed thickening score (STS) and changes of these parameters were obtained. Independent-samples t test and Mann-Whitney U test were used to analyze data. Results:Nine Chinese mini-pigs survived after surgery and were performed imaging. Compared to non-RIC group ( n=4), HM at the 28th ((6.0±2.4)% vs (17.0±4.6)%; t=-4.158), TPD 14th-1st ((-11.8±5.4)% vs 9.0%(4.5%, 15.0%); z=2.449), TPD 28th-1st ((-15.3±3.9)% vs (12.0±3.0)%; t=-10.071), TPD 56th-1st ((-18.0±6.5)% vs 9.0%(4.5%, 12.0%); z=2.449), HM 28th-1st ((-10.5±6.9)% vs (8.3±2.1)%; t=-4.507), HM 56th-1st (-15.0%(-17.5%, -8.5%) vs 2.0%(0%, 7.0%); z=2.449) and LVEDV 14th-1st (-0.5(-2.5, 0) ml vs (13.0±4.4) ml; z=2.470) were reduced in RIC group ( n=5; all P<0.05). Conclusion:RIC can improve myocardial perfusion, delay LV remodeling in the acute stage and salvage hibernating myocardium in the subacute stage and chronic stage.
