To investigate the levels of neurofilaments (NFs) in transgenic mice and patients with spinal muscular atrophy (SMA), and to evaluate their efficacy as a biomarker in SMA.

The levels of NF mRNA transcripts were measured by quantitative real-time PCR in spinal cord from SMA mice. Blood levels of NF heavy chain (NfH) from mice and patients were measured by an in-house ELISA method. The response of NFs to therapeutic intervention was analysed in severe SMA mice treated with morpholino antisense oligonucleotides.

Significant changes in NF transcript and protein in spinal cord and protein levels in blood were detected in SMA mice with severe or mild phenotypes, at different time points. A decrease in blood levels of NfH after antisense oligonucleotide treatment was only transient in the mice, despite the persistent benefit on the disease phenotype. A drastic reduction of over 90% in blood levels of NfF was observed in both control and SMA mice during early postnatal development. In contrast, blood levels of NfH were found to be decreased in older SMA children with chronic disease progression.

Our results show that blood NfH levels are informative in indicating disease onset and response to antisense oligonucleotides treatment in SMA mice, and indicate their potential as a peripheral marker reflecting the pathological status in central nervous system. In older patients with chronic SMA, however, the lower NfH levels may limit their application as biomarker, highlighting the need to continue to pursue additional biomarkers for this group of patients.

A recently described phenotype with fusiform aneurysm has been associated with mosaic PDGFRB c.1685A > G p.(Tyr562Cys) variant. Few reports however have examined the vascular phenotypes and mosaic effects of PDGFRB variants. We describe clinical characteristics of two patients with a recurrent mosaic PDGFRB p.(Tyr562Cys) variant identified via next-generation sequencing-based genetic testing. We observed intracranial fusiform aneurysm in one patient and found an additional eight patients with aneurysms and phenotypes associated with PDGFRB-activating variants through literature search. The conditions caused by PDGFRB-activating variants share overlapping features including overgrowth, premature aged skin, and vascular malformations including aneurysms. Aneurysms are progressive and can result in morbidities and mortalities in the absence of successful intervention. Germline and/or somatic testing for PDGFRB gene should be obtained when PDGFRB activating variant-related phenotypes are present. Whole-body imaging of the arterial tree and echocardiography are recommended after diagnosis. Repeating the imaging study within a 6- to 12-month period after detection is reasonable. Finally, further evaluation for the effectiveness and safety profile of kinase inhibitors in this patient population is warranted.Variants identified by genome-wide association studies (GWAS) are often expression quantitative trait loci (eQTLs), suggesting they are proxies or are themselves regulatory. Across many data sets, analyses show that variants often affect multiple genes. Lacking data on many tissue types, developmental time points, and homogeneous cell types, the extent of this one-to-many relationship is underestimated. This raises questions on whether a disease eQTL target gene explains the genetic association or is a bystander and puts into question the direction of expression effect of on the risk, since the many variants-regulated genes may have opposing effects, imperfectly balancing each other. We used two brain gene expression data sets (CommonMind and BrainSeq) for mediation analysis of schizophrenia-associated variants. We confirm that eQTL target genes often mediate risk but the direction in which expression affects risk is often different from that in which the risk allele changes expression. Of 38 mediator genes significant in both data sets 33 showed consistent mediation direction (Chi2 test p = 6 × 10-6 ). One might expect that the expression would correlate with the risk allele in the same direction it correlates with the disease. For 15 of these 33 (45%), however, the expression change associated with the risk allele was protective, suggesting the likely presence of other target genes with overriding effects. STAT inhibitor Our results identify specific risk mediating genes and suggest caution in interpreting the biological consequences of targeted modifications of gene expression, as not all eQTL targets may be relevant to disease while those that are, might have different from expected directions.

To assess and compare corneal sub-basal nerve plexus morphology with circulating lymphocyte subsets, immunologic status and disease activity in Sjögren syndrome (SjS) patients.

Fifty-five SjS patients, 63 Sicca patients (not fulfilling SjS criteria), 18 rheumatoid arthritis (RA) patients and 20 healthy controls (HC) were included. Systemic disease activity in SjS was assessed with the ESSDAI score. Lymphocyte subpopulations were studied with flow cytometry. Corneal confocal microscopy and ImageJ software were used to characterize corneal sub-basal nerve plexus in terms of nerve density (CNFD), length (CNFL) and tortuosity (CNFT). Conventional dry eye tests were also performed.

CNFL and CNFD were lower in SjS, Sicca and RA groups, compared to HC (p<0.001 for both SjS and Sicca); CNFL p=0.005, CNFD p=0.018 in RA). CNFT was higher in SjS, followed by Sicca, RA and HC. A negative correlation was found between ESSDAI score and CNFL (r=-0.735, p=0.012). CNFL correlated negatively with IL21

CD8

T cells (r=-0.279, p=0.039) and a positively with total memory (r=0.299, p=0.027), unswitched memory (r=0.281, p=0.038) and CD24

CD27

(r=0.278, p=0.040) B cells. CNFD showed a tendency to significance in its negative correlation with ESSDAI (r=-0.592, p=0.071) and in its positive correlation with switched memory B cells (r=0.644, p=0.068).

This is the first study aiming to correlate ocular findings with lymphocyte subsets in SjS. The associations founded between CNFL and CNFD and disease activity, IL21

follicular T cells and some B-cell subsets suggest that corneal nerve damage may parallel systemic disease activity and inflammatory cells' dynamics.

To compare peramivir 300mg single-dose, peramivir 600mg repeat-dose, and oseltamivir effects on health-related quality of life, including respiratory symptoms and general conditions, time to symptom alleviation, time to fever resolution, incidence of exacerbations, and virus titer, in influenza patients with chronic respiratory disease.

We report additional outcomes from a 2-week, multicenter, randomized, open-label study in Japan (UMIN000030118). Influenza patients with chronic respiratory disease received intravenous peramivir (300mg single-dose [n=66], 600mg repeat-dose [600mg/d of 2 consecutive days; n=70]) or oral oseltamivir (75mg twice daily, 5days; n=72). The principal endpoint of this analysis was change from baseline to Day 14 at each time point in Chronic Obstructive Pulmonary Disease Assessment Test (CAT) scores.

Both peramivir regimens reduced total CAT score at Day 3 more than oseltamivir (peramivir 600mg vs oseltamivir, P=.0032; peramivir 300mg vs oseltamivir, P=.0203). Cough/phlegm CAT scores were most improved with peramivir 600mg. Median time to alleviation of three respiratory symptoms was longer with peramivir 600mg (68.9hours) than with peramivir 300mg (50.6hours, hazard ratio [HR] 1.57; P=.0191) and shorter with peramivir 300mg than oseltamivir (78.8hours, HR 0.62; P=.0141). Alleviation of seven influenza symptoms and fever resolution was shortest with peramivir 300mg.

Rapid improvement in CAT score, including cough, and shorter time to alleviation of respiratory symptoms associated with peramivir is of potential benefit to patients with chronic respiratory disease.

While clinical validity of ADOS-2 Modules 1-4 have been extensively studied, there has been very limited research examining the clinical validity of ADOS-2 Toddler Module. The goal of this study was to examine alignment of the ADOS-2 Toddler Module classification with clinicians' determination of ASD, with assessing cut-off scores for diagnosing ASD in toddlers. A total of 412 toddlers ages 12-30 months who received ADOS-2 Toddler Module as well as a best estimate clinical (BEC) diagnosis, were included in this study. ADOS-2 Toddler Module cut-off scores were determined using the appropriate algorithms (Algorithm 1 for toddlers aged 12-20 months and those aged 21-30 months with less then 5 words, Algorithm 2 for toddlers aged 21-30 months with 5 words or more). Receiver operating characteristic (ROC) curves were used to assess cut-off scores that optimized sity of ADOS-2 Toddler Module. Cut-off scores of ADOS-2 Toddler Module cited in the manual yielded best clinical utility for diagnosing ASD in toddlers.A pregnant woman was enrolled in a double-blind randomized controlled trial (RCT) in which participants were randomized to a placebo or a drug being tested to prevent a hypertensive complication. After completing the trial, the research participant insisted on being told which drug she received to prepare for a future pregnancy. This case highlights an element of RCT procedure that has received minimal attention-whether to unblind study participants at the end of their participation. Given that unblinding is not standard practice for nonserious adverse events, what actions are justifiable for the investigators to take? To synthesize the information about this case, we used the CASES model, created by the National Center for Ethics in Health Care to analyze ethics cases. Ethical principles that guide research emphasize communication with participants and the importance of reducing harm within the constraints of the scientific goals. Participants may value knowing which drug they received for future health care decision-making.
