We investigated these questions among elderly participants who sought health consultations in an outpatient clinic. Methods: We conducted a cross-sectional study based on participants from an outpatient clinic, enrolling residents over 60 years of age seeking outpatient services because of abnormal transcranial Doppler reports at Shandong Provincial Third Hospital in Jinan, Shandong province. We performed physical examinations, blood tests, cIMT measurement using carotid ultrasonography, ICAS measurement using brain magnetic resonance angiography scanning, and global cognitive function assessment using the Montreal Cognitive Assessment (MoCA) in the outpatient clinic from May 2020 to December 2020. We subsequently performed a regression analysis to explore the relationship between cIMT and cognitive function and a stratified analysis to explore whether the relationship was different between the ICAS and non-ICAS participants. Results: In total, 167 participants (age: 65.56 ± 10.39 years, female: 53.89%) were included in the present study. The MoCA score was significantly lower in the intimal thickening group (cIMT ≥ 1.0 mm) than in the normal group (mean [SD]: 16.23 [5.16] vs. 19.97 [4.59], P < 0.001). Univariate analysis showed that a greater cIMT was negatively correlated with cognitive function. After adjustment for several potential confounders in the multivariable analyses, the association between cIMT and cognitive function disappeared. When further stratified by ICAS, a negative association between increased cIMT (cIMT ≥ 1.0 mm) and cognitive function was found in those without ICAS (β: ?2.80 [-5.13, ?0.48], p = 0.021); however, in subjects with ICAS, the relationship between cIMT and cognitive function was insignificant. Conclusion: Greater cIMT was associated with low cognitive function in participants without ICAS who sought consultation due to abnormal transcranial Doppler reports in outpatient clinics.

Sixty patients with suspected LGMD from the Neuromuscular Unit, Myology Clinic, Ain Shams University Hospital, Cairo, Egypt, and a series of healthy subjects were included. The patients underwent real-time B-mode ultrasonography performed using a General Electric ultrasound machine (GE Logiq P7) and a General Electric 7.5 MHz linear array ultrasound probe (USA). All images were obtained and scored by a single examiner, and muscle echo intensity was visually graded semiquantitatively using Heckmatt's scale. The examiner was blinded to the clinical evaluations and patients’ investigations. Statistical analysis using receiver operating characteristic (ROC) curve analysis revealed that the total upper-limb (UL) Heckmatt's US score at a cutoff point >1 predicted patients with dystrophy, with good (88%) accuracy and with sensitivity and specificity of 100% and 75%, respectively (p < 0.01). Moreover, the total lower-limbs (LL) Heckmatt's US score at a cutoff point >1 predicted patients with dystrophy, with excellent (91%) accuracy and with sensitivity and specificity of 100% and 75%, respectively (p < 0.01). Finally, the total Heckmatt's US score at a cutoff point >2 predicted patients with dystrophy, with good (89%) accuracy and with sensitivity and specificity of 100% and 75%, respectively (p < 0.01). Thus, MUS can be considered a valid screening tool in the assessment of patients with suspected LGMD.

    查看更多>>摘要:? 2021 Elsevier LtdMyotonic dystrophy (DM) is an autosomal dominant neuromuscular and multisystem disease that is divided into two types, DM1 and DM2, according to mutations in DMPK and CNBP genes, respectively. DM patients may manifest with various speech and language abnormalities. In this review, we had an overview on speech and language abnormalities in both DM1 and DM2. Our literature search highlights that irrespective of age, all DM patients (i.e. congenital, juvenile, and adult onset DM1 as well as DM2 patients) exhibit various degrees of speech impairments. These problems are related to both cognitive dysfunction (e.g. difficulties in written and spoken language) and bulbar/vocal muscles weakness and myotonia. DM1 adult patients have also a significant decrease in speech rate and performance due to myotonia and flaccid dysarthria, which can improve with warming up. Weakness, tiredness, and hypotonia of oral and velopharyngeal muscles can cause flaccid dysarthria. Hearing impairment also plays a role in affecting speech recognition in DM2. A better understanding of different aspects of speech and language abnormalities in DM patients may provide better characterization of these abnormalities as markers that can be potentially used as outcome measures in natural history studies or clinical trials.

    查看更多>>摘要:? 2021 Elsevier LtdCoronavirus disease 2019 (COVID-19) has been associated with Acute Ischemic Stroke (AIS). Here, we characterize our institutional experience with management of COVID-19 and AIS. Baseline demographics, clinical, imaging, and outcomes data were determined in patients with COVID-19 and AIS presenting within March 2020 to October 2020, and November 2020 to August 2021, based on institutional COVID-19 hospitalization volume. Of 2512 COVID-19 patients, 35 (1.39%, mean age 63.3 years, 54% women) had AIS. AIS recognition was frequently delayed after COVID-19 symptoms (median 19.5 days). Four patients (11%) were on therapeutic anticoagulation at AIS recognition. AIS mechanism was undetermined or due to multiple etiologies in most cases (n = 20, 57%). Three patients underwent IV TPA, and three underwent mechanical thrombectomy, of which two suffered re-occlusion. Three patients had incomplete mRNA vaccination course. Fourteen (40%) died, with 26 (74%) having poor outcomes. Critical COVID-19 severity was associated with worsened mortality (p = 0.02). More patients (12/16; 75%) had either worsened or similar 3-month functional outcomes, than those with improvement, indicating the devastating impact of co-existing AIS and COVID-19. Comparative analysis showed that patients in the later cohort had earlier AIS presentation, fewer stroke risk factors, more comprehensive workup, more defined stroke mechanisms, less instance of critical COVID-19 severity, more utilization of IV TPA, and a trend towards worse outcomes for the sub-group of mild-to-moderate COVID-19 severity. AIS incidence, NIHSS, and overall outcomes were similar. Further studies should investigate outcomes beyond 3 months and their predictive factors, impact of completed vaccination course, and access to neurologic care.
