Background: Infections could increase the risk of poor outcome in patients with acute ischemic stroke (AIS). The peripheral neutrophil-to-lymphocyte ratio (NLR) is an important indicator of inflammation. The purpose of our study was to investigate the association increased NLR with post stroke infections (PSI) in AIS. Methods: In this study, we included 606 consecutive patients with AIS within 24 h. The NLR was calculated by dividing absolute neutrophil counts by absolute lymphocyte counts. Receiver operating characteristic (ROC) curve was performed to identify the optimal cut point of NLR for PSI. The relationship between NLR and PSI was analyzed by multivariable analysis. Results: We assessed 606 consecutive patients with AIS. ROC curve analysis showed that the optimal cut point of NLR for PSI was NLR ≥ 5.79. Compared with no PSI, patients with PSI have higher NLR, older age, higher NIHSS, higher PCT, higher percentage of nasogastric tube feeding and indwelling urinary catheter (P < 0.05). Multivariable analysis showed that NLR ≥ 5.79 [adjusted odds ratio (aOR),4.52; 95% confidence interval (CI),3.02-6.76; P < 0.001], older age (aOR,1.03; 95% CI, 1.00-1.05; P = 0.009), higher admission NIHSS (aOR,1.13; 95%CI, 1.07-1.18; P < 0.001), indwelling urinary catheter (aOR1.83; 95%CI, 1.08-3.10; P = 0.026], and nasogastric tube feeding (aOR2.52; 95%CI, 1.38-4.59; P = 0.003) were associated with increased risk of PSI. Conclusions: Higher NLR can predict PSI in AIS patients. The NLR may help to select high-risk patients to start intervention in time.

Background: Stroke has been shown to cause cardiac autonomic dysfunction. Depression is common complication after acute ischemic stroke (AIS). The purpose of this study was to investigate whether decreased heart rate variability (HRV) was related to poststroke depression (PSD) in patients with mild-moderate AIS. Methods: In this study, we assessed autonomic function of ischemic stroke patients within 72 h from symptom onset by fractal dimension (FD). 503 patients (mean age 65.93 ± 10.19) with mild-moderate AIS underwent FD test after admission. Depressive symptoms were assessed using 17-item Hamilton Depression Rating Scale (HDRS) at baseline (within 7 days) and 3 months. Depression were defined if HDRS >6 points. According to the data of FD, we investigated association with early-onset PSD status and 3-month PSD. Results: 59.24% (293/503) of patients had early-onset PSD status at baseline, and 38.66% (184/476) of patients had PSD at 3 months. ROC curve analysis shown that the optimal cut point of FD for early-onset PSD status and 3-month PSD were FD ≤ 1.27 and FD ≤ 1.19, respectively. In fully adjusted models, higher NIHSS [adjusted odd ratios (OR),

Background Patients with acute large vessel occlusion (LVO) presenting with minor stroke are at risk of early neurological deterioration (END). The present study aimed to evaluate the frequency and potential predictors of END in patients with medical management and LVO presenting with minor stroke. The relationship between SVS length and END was also investigated. Methods This was a prospective multicenter study. Consecutive patients were collected with anterior circulation. LVO presented with minor stroke [National Institutes of Health Stroke Scale (NIHSS) ≤ 4] within 24 h following onset. END was defined as a deterioration of NIHSS ≥4 within 24 h, without parenchymal hemorrhage. The length of the susceptibility vessel sign (SVS) was measured using the T2* gradient echo imaging. Results A total of 134 consecutive patients with anterior circulation LVO presenting with minor stroke were included. A total of 27 (20.15%) patients experienced END following admission. Patients with END exhibited longer SVS and higher baseline glucose levels compared with subjects lacking END (P < 0.05). ROC curve analysis indicated that the optimal cutoff point SVS length for END was SVS ≥ 9.45 mm. Multivariable analysis indicated that longer SVS [adjusted odds ratio (aOR), 2.03; 95% confidence interval (CI), 1.45–2.84; P < 0.001] and higher baseline glucose (aOR,1.02; 95% CI, 1.01–1.03; P = 0.009) levels were associated with increased risk of END. When SVS ≥ 9.45 mm was used in the multivariate logistic regression, SVS ≥ 9.45 mm (aOR, 5.41; 95%CI, 1.00–29.27; P = 0.001) and higher baseline glucose [aOR1.01; 95%CI, 1.00–1.03; P = 0.021] were associated with increased risk of END. Conclusions END was frequent in the minor stroke patients with large vessel occlusion, whereas longer SVS and higher baseline glucose were associated with increased risk of END. SVS ≥ 9.45 mm was a powerful independent predictor of END.

ObjectivesTo investigate the associations between risk factors and depression symptoms in ischemic stroke (IS) survivors and the effect of IS survivors’ depression status and functional outcomes on caregiver burden in Chengdu, China.MethodsIn this cross-sectional study, we recruited a convenience sample of patients with IS and paired caregivers living in Chengdu from February 2022 to May 2022. Depression symptoms were assessed using the 17-item Chinese Hamilton Depression Rating Scale, the social support of patients was assessed using the perceived social support scale (PSSS), caregiver burden was assessed using the Zarit burden interview (ZBI). Multivariable logistic regression analysis was used to analyze the data between risk factors and depression symptoms, and multiple linear regression models were constructed to examine the depression symptoms and functional outcomes of stroke survivors, and caregiver burden.ResultsIn total, 966 IS survivors and paired caregivers were included in this study. Among IS survivors, 35.51% (343/966) experienced depression. Age [adjusted odds ratio (aOR), 1.02; 95% confidence interval (CI), 1.00–1.04; p = 0.036], the National Institutes of Health Stroke Scale (NIHSS) score (aOR, 1.57; 95% CI, 1.47–1.68; p &lt; 0.001), and PSSS score (aOR, 0.86; 95% CI, 0.84–0.89; p &lt; 0.001) were associated with an increased risk of depression. The NIHSS score (b = 2.57, p &lt; 0.001), patients’ depression status (b = 2.54, p &lt; 0.001), duration of care (b = 0.359, p = 0.006), and social support of caregivers (b = −0.894, p = 0.038) were significantly associated with the ZBI score.ConclusionThe PSSS score was a major risk factor for the development of depression in IS survivors, and patients’ depression status and severe functional deficits had a negative impact on the ZBI score of the main caregivers. Social support can reduce the ZBI score.

Case PresentationA 77-year-old man with a known history of long-standing hypertension experienced a left cerebellar hemorrhage 9 months ago, then a right cerebellar hemorrhage 3 months prior to his presentation. The patient had noticeable dysphagia that required placing a nasogastric tube for nasal feeding. The standardized swallowing assessment revealed that he had an impairment in lip closure, head, and trunk control, pharyngeal reflex, as well as independent coughing. To observe the pathophysiological changes of the pharynx and larynx, a fiberoptic laryngoscope was inserted prior to the video fluoroscopic swallowing study (VFSS), which showed that there was no pathophysiological change. VFSS detected the rhythmic tremor of the soft palate and epiglottis, with residues displayed in the vallecula and pyriform sinuses.Magnetic resonance imaging (MRI) depicted bilateral long T2 signal shadows in the cerebellum, enlargement of the bilateral olivary nucleus, with a longer T2-weighted signal change. The T2 FLAIR image demonstrated an increased signal change, with the right inferior olivary nucleus (ION) obviously larger than the left.
