The use of immune checkpoint inhibitors to treat urothelial carcinoma (UC) is increasing rapidly without clear guidance for validated risk stratification. This multicenter retrospective study collected clinicopathological information on 463 patients, and 11 predefined variables were analyzed to develop a multivariate model predicting overall survival (OS). The model was validated using an independent dataset of 292 patients. Patient characteristics and outcomes were well balanced between the discovery and validation cohorts, which had median OS times of 10.2 and 12.5 mo, respectively. The final validated multivariate model was defined by risk scores based on the hazard ratios (HRs) of independent prognostic factors including performance status, site of metastasis, hemoglobin levels, and the neutrophil-to-lymphocyte ratio. The median OS times (95% confidence intervals [CIs]) for the low-, intermediate-, and high-risk groups (discovery cohort) were not yet reached (NYR) (NYR-19.1), 6.8 mo (5.8-8.9), and 2.3 mo (1.2-2.6), respectively. The HRs (95% CI) for OS in the low- and intermediate-risk groups vs the high-risk group were 0.07 (0.04-0.11) and 0.23 (0.15-0.37), respectively. The objective response rates for in the low-, intermediate-, and high-risk groups were 48.3%, 28.8%, and 10.5%, respectively. These differential outcomes were well reproduced in the validation cohort and in patients who received pembrolizumab after perioperative or first-line chemotherapy (N = 584). In conclusion, the present study developed and validated a simple prognostic model predicting the oncological outcomes of pembrolizumab-treated patients with chemoresistant UC. The model provides useful information for external validation, patient counseling, and clinical trial design.Crystalline metal halide perovskites (MHPs) have provided unprecedented advances in interdisciplinary fields of materials, electronics, and photonics. While crystallinity offers numerous advantages, the ability to access a glassy state with distinct properties provides unique opportunities to extend the associated structure-property relationship, as well as broaden the application space for MHPs. Amorphous analogs for MHPs have so far been restricted to high pressures, limiting detailed studies and applications. Here, a 2D MHP is structurally tailored using bulky chiral organic cations to exhibit an unusual confluence of exceptionally low melting temperature (175 °C) and inhibited crystallization. The chiral MHP can thus be melt-quenched into a stable glassy state, otherwise inhibited in the analogous racemic MHP. Facile and reversible switching between glassy and crystalline states is demonstrated for the chiral MHP, each with distinct optoelectronic character, opening new opportunities for applications including, for example nonvolatile memory, optical communication, and neuromorphic computing.
Radiographic signs of intervertebral disc mineralization are thought to indicate sites of future recurrence of disc extrusion (Hansen type I) but the relationship between evidence of disc degeneration on magnetic resonance imaging (MRI) and future disc extrusion with recurrence of clinical signs has not been examined.

To examine the relationship between MRI-assessed degeneration of thoracolumbar intervertebral discs and late recurrence of clinical signs in dogs presented with acute thoracolumbar intervertebral disc extrusion and treated by hemilaminectomy alone.

Ninety-two client-owned dogs presented to 2 referral hospitals between 2009 and 2014.

Retrospective analysis of association between clinical signs consistent with recurrent thoracolumbar intervertebral disc extrusion and MRI evidence of disc degeneration in dogs undergoing hemilaminectomy for acute thoracolumbar intervertebral disc extrusion. Univariable and multivariable Cox regression analyses were used to explore associations between recurrence of clinical signs and several characteristics of T10-L3 discs at initial diagnosis.

Ninety-two cases were included, of which 42 (46%) were Dachshunds and median age was 5.3 years. Clinical signs recurred in 33/92 (36%) dogs. Finding a completely degenerate disc in the T10 to L3 region (in addition to the operated site) at the time of surgery was associated with a hazard ratio of 2.92 (95% confidence interval 1.37-6.20) for recurrence of clinical signs.

Our results suggest that in cases of thoracolumbar intervertebral disc extrusion in dogs, recurrence of signs is likely if at least 1 completely degenerate disc in addition to the currently symptomatic disc is visible on MRI.

High-risk neuroblastoma (HR-NB) has a variable response to preoperative chemotherapy. It is not possible to differentiate viable vs. nonviable residual tumor before surgery.

To explore the association between apparent diffusion coefficient (ADC) values from diffusion-weighted magnetic resonance imaging (DW-MRI),
I-meta-iodobenzyl-guanidine (
I-mIBG) uptake, and histology before and after chemotherapy.

Retrospective.

Forty patients with HR-NB.

1.5T axial DW-MRI (b = 0,1000 s/mm
) and T
-weighted sequences.
I-mIBG scintigraphy planar imaging (all patients), with additional
I-mIBG single-photon emission computed tomography / computerized tomography (SPECT/CT) imaging (15 patients).

ADC maps and
I-mIBG SPECT/CT images were coregistered to the T
-weighted images.
I-mIBG uptake was normalized with a tumor-to-liver count ratio (TLCR). Regions of interest (ROIs) for primary tumor volume and different intratumor subregions were drawn. The lower quartile ADC value (ADC
) was used ovnificantly higher in patients with >50% viable tumor than those with 10-50% viable tumor (P < 0.05). DATA CONCLUSION
I-mIBG avidity and ADC values are complementary noninvasive biomarkers of therapeutic response in HR-NB.

3.Osteopetrosis is a rare hereditary bone development disorder caused by osteoclast dysfunction, which increases bone density. Although few studies have investigated cardiovascular disease in osteopetrosis, sternotomy outcomes in this condition are unclear. We report the case of a patient with osteopetrosis and severe mitral regurgitation. A 63-year-old woman with exertional dyspnea had regurgitant systolic murmur audible at the apex. Transthoracic echocardiography showed severe mitral regurgitation due to posterior leaflet prolapse on the anterolateral side. Radiological findings revealed increased bone density (consistent with osteopetrosis). Considering risks in median sternotomy, we performed minimally invasive cardiac surgery through right minithoracotomy for mitral regurgitation. Preoperative imaging showed sclerotic rib changes; nevertheless, sufficient surgical views obtained involved the intercostal space. No residual mitral regurgitation was observed, and the postoperative course was good. To the best of our knowledge, this is the first case report on minimally invasive cardiac surgery for mitral regurgitation with osteopetrosis.
Pronouns are referentially ambiguous (e.g. she could refer to any female), yet they are common in everyday conversations. Individuals with typical development (TD) employ several strategies to avoid pronoun interpretation errors, including the subject bias - an assumption that a pronoun typically refers to the subject (or, with the closely related order-of-mention bias, the first-mentioned character) of the previous sentence. However, it is unknown if adults with intellectual disability (ID) share this strategy or the extent to which the subject bias is associated with non-verbal abilities or receptive vocabulary.

We tested 22 adults with mixed-aetiology ID on their interpretation of ambiguous pronouns using the visual world eye-tracking paradigm and by asking a follow-up pronoun interpretation question. Namodenoson cell line A group of TD adults was also tested to establish the strength of the subject bias with our materials and task.

Adults with ID did demonstrate the subject bias, but it was significantly less robust than that seen in TD. For participants with ID, the subject bias was influenced by non-verbal IQ and receptive vocabulary at different stages of processing.

Given the frequency of pronouns in conversation, strengthening the subject bias may help alleviate discourse and reading comprehension challenges for individuals with ID, particularly those with lower non-verbal and/or vocabulary skills.

Our objectives were to evaluate the risk of adverse events in a 'real-world' vs 'clinical trial' cohort of atrial fibrillation (AF) patients with chronic kidney disease (CKD).

We studied patient-level data for vitamin K antagonist-treated AF patients with a creatinine clearance <60mL/min from the Murcia AF Project and AMADEUS trial. The study end-points were ischaemic stroke, major bleeding, all-cause mortality, myocardial infarction and intracranial haemorrhage.

This study included 1,108 AF patients with CKD. The annual rate of the composite study outcome of ischaemic stroke, major bleeding and all-cause mortality was higher in the real-world (13.4%) vs AMADEUS (6.6%) cohort with an IRR of 2.04 (95% CI,1.34-3.09), P<.001. Individual annual rates of major bleeding, all-cause mortality and non-cardiovascular mortality were significantly greater in the real-world cohort. Similar findings were demonstrated even after multivariable adjustment, with the composite outcome HR of 2.85 (95% CI,1.74-4.66), P<.001. In a propensity score matched cohort, this risk remained significantly higher in the real-world cohort (IRR 2.95 [95% CI,1.03-10.28], P=.027), as did the risk of major bleeding and all-cause mortality.

Vitamin K antagonist-treated AF patients with CKD are exposed to significant annual rates of major adverse events including all-cause mortality. This risk may be under-appreciated in the idealised environment of randomised controlled trials.

In this single-institution study, 50 women with in situ carcinoma were treated with oncoplastic breast-conserving surgery (OPS) and single-dose IORT. All 50 patients had "no tumor on ink," but 9 (16%) had margins less then 2 mm and required additional therapy. No local recurrences were observed after a median follow-up of 46 months. Single-dose IORT is an efficacious treatment for well-selected patients with DCIS.
