To describe the dynamics of brain volume loss (BVL) at different stages of relapsing-remitting multiple sclerosis (RRMS), to describe the association between BVL and clinical measures, and to investigate an effect of treatment escalation on the rate of BVL.

Together, 1903 patients predominantly with RRMS from the Avonex-Steroids-Azathioprine cohort (N = 166), the study of early IFN-β1a treatment cohort (N = 180), and the quantitative MRI cohort (N = 1,557) with ≥2 MRI scans and ≥1-year of follow-up were included. Brain MRI scans (N = 7,203) were performed using a single 1.5-T machine. Relationships between age or disease duration and global and tissue-specific BVL rates were analyzed using mixed models.

Age was not associated with the rate of BVL (β = -0.003; Cohen f2 = 0.0005; adjusted
= 0.39). Although disease duration was associated with the rate of BVL, its effect on the BVL rate was minimal (β = -0.012; Cohen f2 = 0.004; adjusted
= 4 × 10
). Analysis of association between tissue-specific brd timely escalation to high-efficacy immunotherapy helps decrease the rate of BVL.Alternate strategies are needed for B-cell malignancy patients relapsing after CD19-targeted immunotherapy. Here, cell surface proteomics revealed CD72 as an optimal target for poor-prognosis KMT2A/MLL1-rearranged (MLLr) B-ALL, which we further found to be expressed in other B-cell malignancies. Using a recently-described, fully-in vitro system we selected synthetic CD72-specific nanobodies, incorporated them into CARs, and demonstrated robust activity against B-cell malignancy models, including CD19 loss. Taking advantage of CD72's role in inhibiting B-cell receptor signaling, we found that pharmacologic SHIP1 inhibition increased CD72 surface density. We establish CD72-nanobody CAR T's as a promising therapy for MLLr B-ALL.Immunotherapies targeting aspects of T cell functionality are efficacious in many solid tumors, but pancreatic ductal adenocarcinoma (PDAC) remains refractory to these treatments. Deeper understanding of the PDAC immune ecosystem is needed to identify additional therapeutic targets and predictive biomarkers for therapeutic response and resistance monitoring. To address these needs, we quantitatively evaluated leukocyte contexture in 135 human PDACs at single-cell resolution by profiling density and spatial distribution of myeloid and lymphoid cells within histopathologically defined regions of surgical resections from treatment-naive and presurgically (neoadjuvant)-treated patients and biopsy specimens from metastatic PDAC. Resultant data establish an immune atlas of PDAC heterogeneity, identify leukocyte features correlating with clinical outcomes, and, through an in silico study, provide guidance for use of PDAC tissue microarrays to optimally measure intratumoral immune heterogeneity. Atlas data have direct applicability as a reference for evaluating immune responses to investigational neoadjuvant PDAC therapeutics where pretherapy baseline specimens are not available. SIGNIFICANCE We provide a phenotypic and spatial immune atlas of human PDAC identifying leukocyte composition at steady state and following standard neoadjuvant therapies. selleck These data have broad utility as a resource that can inform on leukocyte responses to emerging therapies where baseline tissues were not acquired.A phase II trial revealed that the novel radiopharmaceutical 177Lu-PSMA-617 is more likely to elicit a prostate-specific antigen response than chemotherapy in men with metastatic castration-resistant prostate cancer. In the TheraP trial, 66% of men treated with 177Lu-PSMA-617 had a PSA response, compared with 37% of men who received cabazitaxel.Oncoplastic surgery allows an increase in the number of indications for conservative breast cancer treatments. However, uncertainty as to whether it can be performed still exists in certain situations such as with multicentric or multifocal lesions, even when the breast volume can accommodate it. With the aid of a virtual reality software, DIVA, allowing the precise visualisation of tumours and breast volumes based entirely on the patient's MRI, we report the ability to rapidly confirm and secure an indication for partial surgery of multiple lesions in a 31-year-old patient. With the described approach, the patient did not have to suffer significant disfigurement from cancerous breast surgery without compromising safety.Pemphigoid gestationis is a rare autoimmune subepidermal bullous dermatosis occurring during pregnancy and post partum. A 32-year-old woman developed itchy urticarial wheals over the trunk and extremities at 6 months of gestation. This was not controlled with antihistamines, and 2 months later, the patient developed multiple vesiculobullous lesions. The patient had an exacerbation 3 weeks post-delivery. She did not go into remission for 6 months post partum despite treatment with prednisolone 40 mg/day, doxycycline 100 mg two times per day and dapsone 100 mg/day. The patient went into remission following treatment with three courses of intravenous immunoglobulin 2 mg/kg/course and 2 doses of rituximab 1 g at a 2-week interval.Granulomatosis with polyangiitis (GPA) is a rare small vessel vasculitis commonly affecting the lungs, upper respiratory tract and kidneys. It is an idiopathic condition but likely due to an autoimmune process, resulting in granulomatous lesions and glomerulonephritis. Upper respiratory tract involvement is commonly seen in patients with GPA. Our case is that of an elderly lady (Mrs C) presenting with sudden onset bilateral deafness. She was later found to have extensive lower respiratory tract involvement although she was never particularly symptomatic of this. The presentation suggested a single organ disorder and led to some initial diagnostic uncertainty. Imaging and laboratory investigations eventually led to the diagnosis and she was successfully treated with corticosteroids and rituximab with good response and hearing improvement. This case highlights the importance of early diagnosis in a rapidly progressive disease which undetected can lead to catastrophic end organ damage and disability.
