Effective connectivity and criminal sentencing decisions: dynamic causal models in laypersons and legal experts.

This magnetic resonance imaging study is designed to obtain relevant implications for criminal justice and explores the effective connectivity underlying expertise. Laypersons and experts considered sentences for remorseful and remorseless defendants, respectively, with and without mitigation, in hypothetical murder cases. Two groups revealed no differential activation. However, dynamic causal modeling analysis found distinct patterns of connectivity associated with subjects' expertise and mitigating factors. In sentencing for remorseful defendants, laypersons showed increased strength in all bidirectional connections among activated regions of Brodmann area (BA) 32, BA23, the right posterior insula, and the precuneus. In contrast, legal experts sentenced based on mitigation reasoning, showed increased strength only in the bidirectional connection between the insula and the precuneus. When sentencing for remorseless ones without mitigation, both laypersons and experts increased the connection strength, but with reverse directionality, between regions; legal experts strengthened connectivity from BA10 to other regions, that is, the right anterior insula and BA23, but the directionality was reversed in laypersons. In addition, the strength of connection to BA32 and BA10 was correlated with changes in punishments by mitigating factors. This is a crucial result that establishes the validity of the connectivity estimates, which were uninformed by the independent (behavioral) differences in the severity of punishment.

Improving compliance with guidelines may lead to favorable clinical outcomes for patients with non-muscle-invasive bladder cancer: A retrospective multicenter study.

OBJECTIVES: Clinical guidelines recommend that patients with non-muscle-invasive bladder cancer (NMIBC) should be treated with appropriate adjuvant therapy. However, compliance with guideline recommendations is insufficient, and this may lead to unfavorable outcomes. We aimed to investigate the level of adherence to guideline recommendations in patients with NMIBC and evaluate the outcomes of those who did and did not receive guideline-recommended therapies. METHODS: We performed a retrospective analysis of patients with histologically diagnosed NMIBC. The percentage of patients with intermediate- and high-risk tumors who received adjuvant intravesical therapy or second transurethral resection (TUR) was calculated. Recurrence-free survival was assessed in patients who did and did not receive the therapies. We conducted a propensity score-matched analysis to compare outcomes between patients with intermediate-risk and T1 NMIBC who did and did not undergo guideline-recommended therapies. RESULTS: Overall, 1204 patients from the Tohoku Urological Evidence-Based Medicine Study Group and Kyoto University Hospital were included. Of patients with intermediate- and high-risk tumors, 91.0% and 74.0% did not receive maintenance bacillus Calmette-Guérin (BCG), respectively. In both groups, significantly better recurrence-free survival was found for patients treated with maintenance BCG. Among patients with T1 NMIBC, only 16.7% underwent guideline-recommended therapies, that is, a second TUR and maintenance BCG. Significantly greater recurrence-free survival was observed in patients who received guideline-recommended therapies compared with propensity-matched patients who did not. CONCLUSIONS: Guideline-recommended therapies may contribute to improvements in outcomes for patients with NMIBC, suggesting that improvements in adherence to clinical guidelines may lead to favorable outcomes.

An Early-Onset Neuronopathic Form of Acid Sphingomyelinase Deficiency: A SMPD1 p.C133Y Mutation in the Saposin Domain of Acid Sphingomyelinase.

Acid sphingomyelinase (ASM) is a lysosomal hydrolase that degrades sphingomyelin into ceramide and phosphocholine. Recent crystallographic studies revealed the functional role of the N-terminal ASM saposin domain. ASM deficiency due to mutations in the ASM-encoding sphingomyelin phosphodiesterase 1 (SMPD1) gene causes an autosomal recessive sphingolipid-storage disorder, known as Niemann-Pick disease Type A (NPA) or Type B (NPB). NPA is an early-onset neuronopathic disorder, while NPB is a late-onset non-neuronopathic disorder. A homozygous one-base substitution (c.398G>A) of the SMPD1 gene was identified in an infant with NPA, diagnosed with complete loss of ASM activity in the patient's fibroblasts. This mutation is predicted to substitute tyrosine for cysteine at amino acid residue 133, abbreviated as p.C133Y. The patient showed developmental delay, hepatosplenomegaly and rapid neurological deterioration leading to death at the age of 3 years. To characterize p.C133Y, which may disrupt one of the three disulfide bonds of the N-terminal ASM saposin domain, we performed immunoblotting analysis to explore the expression of a mutant ASM protein in the patient's fibroblasts, showing that the protein was detected as a 70-kDa protein, similar to the wild-type ASM protein. Furthermore, transient expression of p.C133Y ASM protein in COS-7 cells indicated complete loss of ASM enzyme activity, despite that the p.C133Y ASM protein was properly localized to the lysosomes. These results suggest that the proper three-dimensional structure of saposin domain may be essential for ASM catalytic activity. Thus, p.C133Y is associated with complete loss of ASM activity even with stable protein expression and proper subcellular localization.

Real-world outcomes of patients with renal cell carcinoma, surgically treated at regional hospitals, based on a prospective long-term survey of the pre-robotic era.

PURPOSE: Renal cancer surgery is frequently performed in small regional hospitals in Japan. This study evaluated the outcomes of renal cancer surgery, comparing results from the pre-robotic surgery era with those obtained with robotic surgery. METHODS: This prospective cohort study was conducted on patients who underwent renal cancer surgery between 2008 and 2013 at 14 hospitals, comprising 13 regional hospitals and a university hospital, registered in the Tohoku Urological Evidence-Based Medicine Study Group. The patients' backgrounds; perioperative data; annual postoperative renal function; and prognostic surveys, performed over a median follow-up period of 10 years were obtained. RESULTS: In 930 surgical cases at the 14 registered hospitals, the 10-year recurrence-free survival rates of cT1a, cT1b, cT2, and cT3 were 0.9326, 0.8501, 0.5786, and 0.5101, respectively. Meanwhile, the 10-year overall survival rates were 0.9612, 0.8662, 0.7505, and 0.7209, respectively. Long-term observation in patients with cT1 showed that vessel involvement and high tumor grade were prognostic factors for recurrence. As a noteworthy fact, radical nephrectomy was performed in 53.3% of patients with cT1a at the regional hospitals. However, even in patients with preoperative chronic kidney disease stage 3, radical nephrectomy was not a prognostic factor of renal function. This indicates that compensatory mechanisms had been working for a long time in many patients who underwent radical nephrectomies without hypertension and preoperative proteinuria, which were predictors of end-stage renal disease. CONCLUSION: Based on a prospective long-term survey of the pre-robotic era, our results suggested no difference of the survival outcomes between the university hospital and regional hospitals. Our study provides baseline data to evaluate the outcomes of renal cancer robotic surgery, performed at regional hospitals.

Successful treatment of metastatic bladder pleomorphic giant cell carcinoma with pembrolizumab.

INTRODUCTION: Bladder pleomorphic giant cell carcinoma is a rare and aggressive malignancy with a poor prognosis. There are no reports of immune checkpoint inhibitors for bladder pleomorphic giant cell carcinoma to date. CASE PRESENTATION: A 72-year-old man presented with gross hematuria due to multiple bladder cancers. Despite transurethral bladder resection and intravesical injection of Bacillus Calmette-Guérin, bladder cancer recurred. Nineteen months later, he underwent total cystectomy. Pathological examination revealed bladder giant cell carcinoma. Twenty-eight months later, pembrolizumab was administered due to para-aortic lymph node metastasis. Forty-four months later, the lymph node metastasis disappeared, and pembrolizumab administration was terminated. Fifty-eight months later, the patient has remained in remission at the time of writing. CONCLUSION: Immune checkpoint inhibitors manifest a therapeutic potential in bladder pleomorphic giant cell carcinoma.

Acute eosinophilic pneumonia associated with intravesical bacillus Calmette-Guérin therapy of carcinoma in situ of the bladder.

A 71-year-old man with a history of rheumatoid arthritis was treated with intravesical bacillus Calmette-Guérin (BCG) instillation of 80 mg once-a-week for carcinoma in situ. He developed low-grade fever followed by dyspnea and severe hypoxemia. Radiological and laboratory studies revealed bilateral diffuse reticulonodular infiltrates and hypereosinophilia. A lymphocyte stimulation test for BCG was strongly positive. From these findings, a pulmonary hypersensitivity reaction to immunotherapy was suspected, and therefore, methylprednisolone (500 mg per day) was started. After that, the fever and dyspnea disappeared, the hypereosinophilia was normalised and chest radiography results were clear. The present case is the first reported case of eosinophilic pneumonia following intravesical BCG therapy.

Ultrasound grade of hydronephrosis and severity of renal cortical damage on 99m technetium dimercaptosuccinic acid renal scan in infants with unilateral hydronephrosis during followup and after pyeloplasty.

PURPOSE: We performed ultrasonography and (99m)technetium dimercaptosuccinic acid (DMSA) renal scan in infants with unilateral hydronephrosis during followup and after pyeloplasty to examine the correlation of ultrasound hydronephrosis grade with the severity of renal cortical damage and assess the recovery of renal function in the obstructed kidneys after surgery. MATERIALS AND METHODS: We studied 80 boys and 19 girls with unilateral hydronephrosis detected in the first year of life, including 75 (76%) in whom it was detected prenatally. Ultrasound images were graded according to the Society for Fetal Urology grading system. The severity of renal cortical damage was assessed by DMSA renal scan. Absolute function of the right and left kidneys was estimated by DMSA uptake and relative DMSA uptake was calculated by the formula, relative uptake = uptake in obstructed kidney/total uptake in right and left kidneys x 100%. RESULTS: On ultrasonography grades 1 to 4 hydronephrosis were diagnosed in 9, 21, 19 and 50 kidneys, respectively. On DMSA renal scan cortical damage was detected in 10 kidneys (53%) with grade 3 and 49 (98%) with grade 4 hydronephrosis but not in kidneys with grade 1 or 2 disease. Dysfunction in the obstructed kidney, defined as relative DMSA uptake less than 40%, was noted in 13 patients with grade 4 hydronephrosis. Relative DMSA uptake significantly increased after successful pyeloplasty compared with preoperative uptake (44% +/- 2% versus 40.1% +/- 2%, p <0.01). CONCLUSIONS: Ultrasound grading of hydronephrosis correlates with the severity of cortical damage or the decrease in renal function on DMSA renal scan. Differential renal function on DMSA renal scan may be a useful and less invasive tool for determining surgical indications and examining changes in renal function after surgery.
