We found a significant correlation between 99mTc-DTPA content in brain and both the discrimination index in the novel object recognition test and indoxyl sulfate concentrations in serum. When we added indoxyl sulfate to the drinking water of rats fed an adenine-rich diet, we found an increase in indoxyl sulfate concentrations in serum associated with a stronger impairment in cognition and a higher permeability of the blood-brain barrier. In addition, non-CKD AhR-/- knockout mice were protected against indoxyl sulfate-induced blood-brain barrier disruption and cognitive impairment. Conclusions AhR activation by indoxyl sulfate, a uremic toxin, leads to blood-brain barrier disruption associated with cognitive impairment in animal models of CKD.Objective To explore clinical outcomes in older adults with acute ischemic stroke treated with endovascular thrombectomy (EVT). Methods We included consecutive patients (2014-2016) with an anterior circulation occlusion undergoing EVT from the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN) Registry. We assessed the effect of age (dichotomized at ≥80 years and as continuous variable) on the modified Rankin Scale (mRS) score at 90 days, symptomatic intracranial hemorrhage (sICH), and reperfusion rate. The association between age and mRS was assessed with multivariable ordinal logistic regression, and a multiplicative interaction term was added to the model to assess modification of reperfusion by age on outcome. Results Of the 1,526 patients, 380 (25%) were ≥80 years of age (referred to here as older adults). selleck kinase inhibitor Older adults had a worse functional outcome than younger patients (adjusted common odds ratio [acOR] for an mRS score shift toward better outcome 0.31, 95% confidence interval [CI] 0.24-0.39). Mortality was also higher in older adults (51% vs 22%, adjusted odds ratio 3.12, 95% CI 2.33-4.19). There were no differences in proportion of patients with mRS scores of 4 to 5, sICH, or reperfusion rates. Successful reperfusion was more strongly associated with a shift toward good functional outcome in older adults than in younger patients (acOR 3.22, 95% CI 2.04-5.10 vs 2.00, 95% CI 1.56-2.57, p interaction = 0.026). Conclusion Older age is associated with an increased absolute risk of poor clinical outcome, while the relative benefit of successful reperfusion seems to be higher in these patients. These results should be taken into consideration in the selection of older adults for EVT.Objective To determine the prevalence of and risk factors associated with opioid use in the treatment of migraine, we examined demographics and clinical characteristics of 867 individuals who reported using opioids for the treatment of migraine. Methods We analyzed data from the CaMEO study (Chronic Migraine Epidemiology and Outcomes), a cross-sectional, longitudinal, Internet study, to compare sociodemographics, clinical characteristics, and migraine burden/disability of opioid users vs nonusers. Covariates were entered as categorical or continuous variables. Factors associated with opioid use were identified using nested, multivariable binary logistic regression models. Results Of 2,388 respondents with migraine using prescription medications for acute treatment, 36.3% reported that they currently used or kept on hand opioid medications to treat headaches. Current opioid users had significantly more comorbidities, greater headache-related burden, and poorer quality of life than nonusers. Regression models revealed factors significantly associated with opioid use, including male sex, body mass index, allodynia, increasing monthly headache frequency, Total Pain Index score (excluding head, face, neck/shoulder), anxiety, depression, ≥1 cardiovascular comorbidity, and emergency department/urgent care use for headache in the past 6 months. Self-reported physician-diagnosed migraine/chronic migraine was associated with significantly decreased likelihood of opioid use. Conclusions Of respondents who were using acute prescription medications for migraine, more than one-third used or kept opioids on hand, contrary to guidance. This analysis could not distinguish risk factors from consequences of opioid use; thus further research is needed to guide the development of strategies for reducing the inappropriate use of opioids in migraine.Objective To determine whether objective and quantitative assessment of dysarthria and dysphagia in spinocerebellar ataxia type 2 (SCA2), specifically at pre-ataxic and early disease phases, can act as sensitive disease markers. Methods Forty-six individuals (16 with pre-ataxic SCA2, 14 with early-stage ataxic SCA2, and 16 healthy controls) were recruited in Holguin, Cuba. All participants underwent a comprehensive battery of assessments including objective acoustic analysis, clinician-derived ratings of speech function and swallowing, and quality of life assessments of swallowing. Results Reduced speech agility manifest at the pre-ataxic stage was observed during diadochokinetic tasks, with the magnitude of speech deficit augmented in the early ataxic stage. Speech rate was slower in early-stage ataxic SCA2 compared with pre-ataxic SCA2 and healthy controls. Reduced speech agility and speech rate correlated with disease severity and time to ataxia onset, verifying that speech deficits occur prior to ataxia onset and increase in severity as the disease progresses. Whereas dysphagia was observed in both pre-ataxic and ataxic SCA2, it was not associated with swallowing-related quality of life, disease severity, or time to ataxia onset. Conclusions Speech and swallowing deficits appear sensitive to disease progression in early-stage SCA2, with syllabic rate a viable marker. Findings provide insight into mechanisms of disease progression in early-stage SCA2, signaling an opportunity for stratifying early-stage SCA2 and identifying salient markers of disease onset as well as outcome measures in future early-stage therapeutic studies.Fluorescence microscopy has become a ubiquitous method to observe the location of specific molecular components within cells. However, the resolution of light microscopy is limited by the laws of diffraction to a few hundred nanometers, blurring most cellular details. Over the last two decades, several techniques - grouped under the 'super-resolution microscopy' moniker - have been designed to bypass this limitation, revealing the cellular organization down to the nanoscale. The number and variety of these techniques have steadily increased, to the point that it has become difficult for cell biologists and seasoned microscopists alike to identify the specific technique best suited to their needs. Available techniques include image processing strategies that generate super-resolved images, optical imaging schemes that overcome the diffraction limit and sample manipulations that expand the size of the biological sample. In this Cell Science at a Glance article and the accompanying poster, we provide key pointers to help users navigate through the various super-resolution methods by briefly summarizing the principles behind each technique, highlighting both critical strengths and weaknesses, as well as providing example images.
