Interleukin-12-producing CD103+ CD11b- CD8+ dendritic tissue have the effect of eliciting belly intraepithelial lymphocyte response against Encephalitozoon cuniculi.
Canonical RAS-associated genes, inflammation-associated genes, and senescence-associated genes were highly expressed in skeletal muscles of AT2/Mas knockout mice. Muscle angiotensin II content increased in AT2/Mas knockout mice. Baf-A1 nmr Conclusions Double deletion of AT2 and Mas in mice exaggerated aging-associated muscle weakness, accompanied by signatures of activated RAS, inflammation, and aging in skeletal muscles. Because aging-associated phenotypes were absent in single deletions of the receptors, AT2 and Mas could complement each other in preventing local activation of RAS during aging.BACKGROUND The United States (US)-Mexico border is a socioeconomically underserved area. We sought to investigate whether stroke-related mortality varies between the US border and nonborder counties. METHODS AND RESULTS We used death certificates from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database to examine stroke-related mortality in border versus nonborder counties in California, Texas, New Mexico, and Arizona. We measured average annual percent changes (AAPCs) in age-adjusted mortality rates (AAMRs) per 100 000 between 1999 and 2018. Overall, AAMRs were higher for nonborder counties, older adults, men, and non-Hispanic Black adults than their counterparts. Between 1999 and 2018, AAMRs reduced from 55.8 per 100 000 to 34.4 per 100 000 in the border counties (AAPC, -2.70) and 64.5 per 100 000 to 37.6 per 100 000 in nonborder counties (AAPC, -2.92). The annual percent change in AAMR initially decreased, followed by stagnation in both border and nonborder counties since 2012. The AAPC in AAMR decreased in all 4 states; however, AAMR increased in California's border counties since 2012 (annual percent change, 3.9). The annual percent change in AAMR decreased for older adults between 1999 and 2012 for the border (-5.10) and nonborder counties (-5.01), followed by a rise in border counties and stalling in nonborder counties. Although the AAPC in AAMR decreased for both sexes, the AAPC in AAMR differed significantly for non-Hispanic White adults in border (-2.69) and nonborder counties (-2.86). The mortality decreased consistently for all other ethnicities/races in both border and nonborder counties. CONCLUSIONS Stroke-related mortality varied between the border and nonborder counties. Given the substantial public health implications, targeted interventions aimed at vulnerable populations are required to improve stroke-related outcomes in the US-Mexico border area.Ventricular arrest is a rare arrhythmic disease in the clinic; 35% to 55% of cases are associated with atrial fibrillation (AF). It is well known that ventricular arrest for ≥3 seconds can lead to brain symptoms such as dizziness and even syncope, but it is not clear whether ventricular pauses (≥3 seconds) with AF will lead to sudden cardiac death. If the implantation of a pacemaker can improve the quality of life of patients with permanent AF with ventricular arrest and whether it has a long-term protective effect on sudden cardiac death. To this end, we conducted a prospective follow-up observation study, which was conducted through telephone interviews and clinical hospital observation to obtain information on the quality of life, survival rate, and other details. The results show that for patients with permanent AF with ventricular arrest, pacemaker implantation cannot reduce sudden cardiac death, cardiovascular events, and stroke nor can it improve the cumulative survival rate. Fortunately, the implantation of pacemakers can improve the quality of life of patients.Background Assessment of the social determinants of post-hospital cardiac care is needed. We examined the association and predictive ability of neighborhood-level determinants (area deprivation index, ADI), readmission risk, and mortality for heart failure, myocardial ischemia, and atrial fibrillation. Methods and Results Using a retrospective (January 1, 2011-December 31, 2018) analysis of a large healthcare system, we assess the predictive ability of ADI on 30-day and 1-year readmission and mortality following hospitalization. Cox proportional hazards models analyzed time-to-event. link2 Log rank analyses determined survival. C-statistic and net reclassification index determined the model's discriminative power. Covariates included age, sex, race, comorbidity, number of medications, length of stay, and insurance. The cohort (n=27 694) had a median follow-up of 46.5 months. There were 14 469 (52.2%) men and 25 219 White (91.1%) patients. Patients in the highest ADI quintile (versus lowest) were more likely to be admitted within 1 year of index heart failure admission (hazard ratio [HR], 1.25; 95% CI, 1.03‒1.51). Patients with myocardial ischemia in the highest ADI quintile were twice as likely to be readmitted at 1 year (HR, 2.04; 95% CI, 1.44‒2.91]). Patients with atrial fibrillation living in areas with highest ADI were less likely to be admitted within 1 year (HR, 0.79; 95% CI, 0.65‒0.95). As ADI increased, risk of readmission increased, and risk reclassification was improved with ADI in the models. Patients in the highest ADI quintile were 25% more likely to die within a year (HR, 1.25 1.08‒1.44). Conclusions Residence in socioeconomically disadvantaged communities predicts rehospitalization and mortality. Measuring neighborhood deprivation can identify individuals at risk following cardiac hospitalization.
Recently, several serum biomarkers have been proposed in Neuromyelitis Optica Spectrum Disorders (NMOSD) to monitor disease activity.

The objective of the study is to evaluate the longitudinal clinical value of serum biomarkers in patients with NMOSD.

We prospectively recruited consecutive NMOSD patients with anti-aquaporin-4 antibody and obtained serum samples at enrollment, after 6-12 months of follow-up (main period), and at attacks. Using single-molecule array assays, we evaluated longitudinal changes of serum neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), and GFAP/NfL levels.

Overall, 64 patients (58 women) were enrolled (age 51 years, disease duration 6.7 years) and 133 samples were obtained. Among patients who did not develop new attacks during the main period (
 = 62), serum levels of NfL, GFAP, and GFAP/NfL were significantly decreased over time in patients with attacks (<2 months) at enrollment (
 = 14 (23%)), whereas serum NfL and GFAP levels gradually increased in the others (
 = 48 (77%)). During the study, five (8%) patients developed new attacks; only serum GFAP levels increased consistently upon these events compared with baseline levels. To differentiate attacks from remissions, serum GFAP levels showed the largest area under the receiver operating characteristic curve (0.876, 95% confidence interval 0.801-0.951).

Among NfL, GFAP, and GFAP/NfL, serum GFAP might be the most appropriate for monitoring NMOSD longitudinally, which warrants future confirming studies.

Limited studies have described long-term outcomes in pathology confirmed multiple sclerosis (MS).

To describe long-term clinical-radiographic-cognitive outcomes in a prospectively followed cohort of patients with pathologically confirmed CNS demyelinating disease, consistent with MS.

Subjects underwent clinical assessment, standardized 3T-MRI brain, and cognitive battery.

Seventy-five patients were included. Biopsied lesion size was ⩾ 2 cm in 62/75. At follow-up, median duration since biopsy was 11 years. link3 Median EDSS was 3 and lesion burden was large (median 10 cm
). At follow-up, 57/75 met MS criteria, 17/75 had clinically isolated syndrome, and 1 radiographic changes only. Disability scores were comparable to a prevalence cohort in Olmsted County (
< 0.001,
= 218). Cognitive outcomes below age-normed standards included psychomotor, attention, working memory, and executive function domains. Total lesion volume and index lesion-related severity correlated with EDSS and cognitive performance. Volumetric cortical/subcortical GM correlated less than lesion metrics to cognitive outcomes.

Despite early aggressive course in pathologically confirmed MS, its long-term course was comparable to typical MS in our study. Cognitive impairment in this group seemed to correlate strongest to index lesion severity and total lesion volume. It remains to be established how the aggressive nature of the lesion, biopsy, and treatment affect clinical/cognitive outcomes.

Suboptimal performance during neuropsychological assessment renders cognitive test results invalid. However, suboptimal performance has rarely been investigated in multiple sclerosis (MS).

To investigate potential underlying mechanisms of suboptimal performance in MS.

Performance validity testing, neuropsychological assessments, neuroimaging, and questionnaires were analyzed in 99 MS outpatients with cognitive complaints. Based on performance validity testing patients were classified as valid or invalid performers, and based on neuropsychological test results as cognitively impaired or preserved. Group comparisons and correlational analyses were performed on demographics, patient-reported, and disease-related outcomes.

Twenty percent displayed invalid performance. Invalid and valid performers did not differ regarding demographic, patient-reported, and disease-related outcomes. Disease severity of invalid and valid performers with cognitive impairment was comparable, but worse than cognitively preserved valid performers. Lower performance validity scores related to lower cognitive functioning, lower education, being male, and higher disability levels (
 < 0.05).

Suboptimal performance frequently occurs in patients with MS and cognitive complaints. In both clinical practice and in cognitive research, suboptimal performance should be considered in the interpretation of cognitive outcomes. Identification of factors that differentiate between suboptimal and optimal performers with cognitive impairment needs further exploration.

SHORT syndrome is a rare autosomal dominant condition described by its acronym of short stature, hyperextensibility of joints and/or inguinal hernia, ocular depression, Rieger abnormality, and teething delay. Individuals have a distinct progeroid craniofacial appearance with a triangular face, frontal bossing, hypoplastic or thin alae nasi, large low-set ears, and mandibular retrognathia.

To systematically appraise the literature and update the clinical phenotype with emphasis on the dental condition.

A systematic literature search was carried out to update the clinical phenotype, identifying reports of individuals with SHORT syndrome published after August 2015. The same search strategy but not limited to publication date was carried out to identify reports of the dental phenotype. Two independent reviewers screened 1937 articles with 55 articles identified for full-text review.

Nineteen individuals from 11 families were identified. Facial dysmorphism including ocular depression, triangular shaped face, frontal bossing, large low-set ears, and micrognathia were the most consistent features followed by lipodystrophy, insulin resistance, and intrauterine growth restriction.
