Notes

Using the electric wellness record to evaluate the particular truth of the present RVU system regarding radiologists.
Including the present case, there have been 6 reported cases of AQP4-IgG-seropositive NMOSD associated with ovarian teratoma (mean onset age, 32.7 years). Of these patients, 5 (83%) presented with nausea and/or vomiting, positive OCB, and dorsal brainstem involvement. Pathologic analyses of the teratoma were available in 5 cases, including the present case, revealing neural tissue with AQP4 immunoreactivity and lymphocyte infiltration in all cases.

This study suggests that ovarian teratoma may trigger the development of AQP4-IgG-seropositive NMOSD. Further studies are needed to elucidate the pathogenesis of teratoma-associated NMOSD.

To study the link between a high body mass index (BMI) in childhood and the occurrence of pediatric-onset multiple sclerosis (POMS) and to compare, within the MS population, the clinical-radiologic-biological characteristics, according to BMI.

A case-control study comparing BMI data of 60 patients with POMS (39 girls and 21 boys) at Bicêtre Hospital with that of 113 non-neurologic controls NNCs (68 girls and 45 boys) and 18,614 healthy controls HCs (9,271 girls and 9,343 boys) was performed. Crude BMI (cBMI), residual BMI (rBMI = measured BMI - expected BMI for age),
-score (rBMI/SD), and adult equivalent categories (International Obesity Task Force ≥25 = overweight, ≥30 = obese) were assessed.

In boys, cBMI and rBMI were significantly higher in patients with POMS compared with NNCs (cBMI +2.9; rBMI +2.95,
< 0.01) and HCs (cBMI +2.04,
< 0.01). In girls, cBMI or rBMI did not differ between POMS and NNCs patients (cBMI
= 0.4; rBMI
= 0.44) but with HCs (cBMI +0.99,
< 0.01). CSF inflammatory markers increased with BMI in prepubertal patients (
< 0.01), whereas vitamin D level at diagnosis was lower in boys with higher BMI (
= 0.016). Increased BMI was not associated with clinical and radiologic disease characteristics.

Overweight and obesity are more frequently observed at diagnosis, particularly in boys with POMS compared with non-neurologic controls and French HCs. Moreover, BMI is related to initial inflammation in the CSF in prepubertal patients with POMS suggesting an interaction between excess body fat, sexual hormones, and POMS occurrence.

We report a combination of BK virus-specific T cells and pembrolizumab as a treatment option in progressive multifocal leukoencephalopathy (PML).

A 57-year-old male patient diagnosed with PML presented a fast-progressing right hemiparesis, aphasia, and cognitive deficits. Brain MRI showed a severe leukoencephalopathy with diffusion restriction. The patient was treated with 10 doses of pembrolizumab (2 mg/kg body weight) in differing intervals and 2 partially human leukocyte antigen-matched allogenic BK virus-specific T cell transfusions after the fifth pembrolizumab treatment. Although pembrolizumab alone decreased the viral load but failed to control the virus, BK-specific T cell transfer further enhanced the decline of JC virus copies in the CSF. Moreover, the regression of leukoencephalopathy and disappearance of diffusion restriction in subsequent brain MRI were observed. The combined treatment resulted in a clinical stabilization with improvements of the cognitive and speech deficits.

This case supports the hypothesis that pembrolizumab is more efficient in the presence of an appropriate number of functional antigen-specific T cells. Thus, the combined treatment of pembrolizumab and virus-specific T cells should be further evaluated as a treatment option for PML in future clinical trials.

To investigate whether serum levels of contactin-1, a paranodal protein, correlate with paranodal injury as seen in patients with CIDP with antibodies targeting the paranodal region.

Serum contactin-1 levels were measured in 187 patients with CIDP and 222 healthy controls. Paranodal antibodies were investigated in all patients.

Serum contactin-1 levels were lower in patients (N = 41) with paranodal antibodies compared with patients (N = 146) without paranodal antibodies (
< 0.01) and showed good discrimination between these groups (area under the curve 0.84; 95% CI 0.76-0.93).

These findings suggest that serum contactin-1 levels have the potential to serve as a possible diagnostic biomarker of paranodal injury in CIDP.

This study provides class II evidence that serum contactin-1 levels can discriminate between patients with CIDP with or without paranodal antibodies with a sensitivity of 71% (95% CI 56%-85%) and a specificity of 97% (95% CI 83%-100%).

These activities include transcription factor (TF)-DNA binding, enhancer activity, open chromatin, and more. A major goal is to understand underlying sequence components, or motifs, that can explain the measured activity. It is usually not one motif but a combination of motifs bound by cooperatively acting proteins that confers activity to such regions. Neuronal Signaling inhibitor Furthermore, regions can be diverse, governed by different combinations of TFs/motifs. Current approaches do not take into account this issue of combinatorial diversity. We present a new statistical framework, cisDIVERSITY, which models regions as diverse modules characterized by combinations of motifs while simultaneously learning the motifs themselves. Because cisDIVERSITY does not rely on knowledge of motifs, modules, cell type, or organism, it is general enough to be applied to regions reported by most high-throughput assays. For example, in enhancer predictions resulting from different assays-GRO-cap, STARR-seq, and those measuring chromatin structure-cisDIVERSITY discovers distinct modules and combinations of TF binding sites, some specific to the assay.
