BACKGROUND: Cerebral stroke is a disease with a high disability rate and a high fatality rate. This study was undertaken to assess the risk of stroke associated pneumonia (SAP) in patients with ischemic stroke using A2DS2 score. METHODS:Altogether 1 279 patients with ischemic stroke who were treated in our department from 2009 to 2011 were retrospectively analyzed with A2DS2 score. A2DS2 score was calculated as follows: age ≥75 years=1, atrial fi brillation=1, dysphagia=2, male sex=1; stroke severity: NIHSS score 0-4=0, 5-15=3, ≥16=5. The patients were divided into three groups according to A2DS2 score: 620 in score 0 group, 383 in score 1-9 group, and 276 in score ≥10 group. The three groups were comparatively analyzed. The diagnostic criteria for SAP were as follows: newly emerging lesions or progressively infiltrating lesions on post-stroke chest images combined with more than two of the following clinical symptoms of infection: (1) fever ≥38 °C; (2) newly occurred cough, productive cough or exacerbation of preexisting respiratory tract symptoms with or without chest pain; (3) signs of pulmonary consolidation and/or wet rales; (4) peripheral white blood cell count ≥10×10 9 /L or ≤4×10 9 /L with or without nuclear shift to left, while excluding some diseases with clinical manifestations similar to pneumonia, such as tuberculosis, pulmonary tumors, non-infectious interstitial lung disease, pulmonary edema, pulmonary embolism and atelectasis. The incidence and mortality of SAP as well as the correlation with ischemic stroke site were analyzed in the three groups respectively. Mean± standard deviation was used to represent measurement data with normal distribution and Student's t test was used. The chi-square test was used to calculate the percentage for enumeration data. RESULTS:The incidence of SAP was significantly higher in the A2DS2 score≥10 group than that in the score 1-9 and score 0 groups (71.7% vs. 22.7%, 71.7% vs. 3.7%, respectively), whereas the mortality in the score≥10 group was signifi cantly higher than that in the score 1-9 and score 0 groups (16.7% vs. 4.96%, 16.7% vs. 0.3%, respectively). The incidences of cerebral infarction in posterior circulation and cross-MCA, ACA distribution areas were signifi cantly higher than those in the SAP group and in the non-SAP group (35.1% vs.10.1%, 11.4% vs. 7.5%, respectively). The incidence of non-fermentative bacteria infection was signifi cantly increased in the score≥10 group.CONCLUSIONS: A2DS2 score provides a basis for risk stratifi cation of SAP. The prevention of SAP needs to be strengthened in acute ischemic stroke patients with a A2DS2 score≥10.

“…However, it is unknown whether other types of SES perturbation would cause different EBL outcomes on swallowing hyolaryngeal elevation. This has relevance to dysphagia rehabilitation because neck SES is used to treat dysphagia using various stimulation protocols with conflicting reports about improvements in swallowing ability (Clark, Lazarus, Arvedson, Schooling, & Frymark, 2009;Huckabee & Doeltgen, 2007;Humbert, Michou, MacRae, & Crujido, 2012;Poorjavad, Talebian Moghadam, Nakhostin Ansari, & Daemi, 2014;Tan, Liu, Li, Liu, & Chen, 2013).…”

Purpose: Error-based learning (EBL) involves gradually reducing movement errors caused by a perturbation. When the perturbation has been unexpectedly removed, exaggerated movements occur in the opposite direction of a perturbation effect, known as aftereffects. Our goal was to determine whether the perturbation type impacts error reduction or aftereffects in swallowing hyolaryngeal kinematics. Method: We perturbed peak hyolaryngeal elevation during swallowing in 16 healthy adults with surface electrical stimulation (SES) in 2 different ways during videofluoroscopy: intermittent SES (I-SES) was applied only during swallowing, and continuous SES (C-SES) was applied during swallowing and during interswallow intervals. In C-SES and I-SES, the onset and offset of the perturbation were unmasked. Results: Only the C-SES perturbation caused error reduction (gradually increasing peak elevation). Aftereffects were absent in both perturbations, unlike findings from our previous study with masked perturbation. Furthermore, the duration of laryngeal vestibule closure (dLVC) increased during the I-SES perturbation but was unchanged during C-SES perturbation. Conclusion: EBL of swallowing airway protection events was strongly influenced by the context of the perturbation. These findings also elucidate how the relationship among critical swallowing airway protection events (hyoid peak, laryngeal peak, and dLVC) can be modified during EBL.

“…The rationale for applying NMES is to stimulate muscle fibers by stimulating the nerve and the motor end plate of the nerve, resulting in the re-education of functional muscle contraction patterns. NMES is commonly applied in post-stroke dysphagia, but is also effective for dysphagia patients of various etiologies [11,12]. Exercise rehabilitation for dysphagia consists of exercises to train specific muscles associated with swallowing.…”
