Clinically Significant Prostate Cancer Prediction Using Multimodal Deep Learning with Prostate-Specific Antigen Restriction.

Prostate cancer (PCa) is a clinically heterogeneous disease. Predicting clinically significant PCa with low-intermediate prostate-specific antigen (PSA), which often includes aggressive cancers, is imperative. This study evaluated the predictive accuracy of deep learning analysis using multimodal medical data focused on clinically significant PCa in patients with PSA ≤ 20 ng/mL.

The Current Status of Comprehensive Genomic Profiling in the Management of Metastatic Castration-Resistant Prostate Cancer: A Study from a Cooperative Hospital for Cancer Genomic Medicine in Japan.

Background: Several effective treatment modalities against metastatic castration-resistant prostate cancer (mCRPC) are available; however, an unmet clinical need persists for mCRPC treatment because resistance to these therapies is inevitable. This study aimed to evaluate the status of comprehensive genomic profiling (CGP) and its impact on subsequent treatments for patients with mCRPC at our hospital.

Methods: Between December 2020 and August 2023, we assessed 41 patients with mCRPC who underwent CGP testing at the Nippon Medical School Hospital.

snRNAs from Radical Prostatectomy Specimens Have the Potential to Serve as Prognostic Factors for Clinical Recurrence after Biochemical Recurrence in Patients with High-Risk Prostate Cancer.

In patients with high-risk prostate cancer (HRPC) after radical prostatectomy (RP), biochemical recurrence (BCR) increases the risk of distant metastasis. Accordingly, additional prognostic biomarkers are required to identify the subpopulation of patients with HRPC who develop clinical recurrence (CR) after BCR. The objective of this study was to identify biomarkers in formalin-fixed paraffin-embedded (FFPE) RP samples that are prognostic for CR in patients with HRPC who experience BCR after RP (post-RP BCR).

Mizoribine halts kidney fibrosis in childhood IgA nephropathy: association with modulation of M2-type macrophages.

Background: The immunosuppressant mizoribine (Miz) can reduce progression of childhood IgA nephropathy (IgAN). This study examined whether Miz affects CD163 M2-type macrophages which are associated with kidney fibrosis in childhood IgAN.

Methods: A retrospective cohort of 90 children with IgAN were divided into groups treated with prednisolone (PSL) alone (P group; n = 42) or PSL plus Miz (PM group; n = 48) for a 2-year period.

Efficacy and Safety of Transurethral Enucleation with Bipolar Energy for Treatment of Benign Prostatic Hyperplasia: Does Prostate Volume Matter?

Background: We evaluated the association of prostate volume (PV) with the efficacy and safety of transurethral enucleation with bipolar energy (TUEB) for treatment of benign prostatic hyperplasia (BPH).

Methods: We retrospectively evaluated data from 180 patients with symptomatic BPH who underwent TUEB between 2008 and 2015. Efficacy was assessed by perioperative changes in international prostate symptom score (IPSS), Quality of Life Score (QOLS), maximum flow rate on uroflowmetry (Qmax), and serum prostate-specific antigen level (PSA), which were recorded at 3 months postoperatively.

Three-dimensional Analysis of Factors Related to the Effective Alveolar Molding in Presurgical Infant Orthopedics: Findings From a Pilot Study.

Objective: Presurgical infant orthopedics (PIO) reduces the severity of the original cleft and burden on patients and their parents, provides better esthetics and function, and enables surgeons to achieve better surgical repair. To reduce the alveolar cleft width and to predict treatment difficulty using PIO, various measures were examined in pretreatment cast models.

Design: Retrospective case-control pilot study.

Steroid treatment promotes an M2 anti-inflammatory macrophage phenotype in childhood lupus nephritis.

Background: M1-type proinflammatory macrophages (MΦ) promote glomerular injury in lupus nephritis (LN). However, whether this phenotype is altered by steroid therapy is unclear. Therefore, we investigated the effect of steroid treatment on MΦ phenotype in LN.

Caldecrin inhibits lipopolysaccharide-induced pro-inflammatory cytokines and M1 macrophage polarization through the immunoreceptor triggering receptor expressed in myeloid cells-2.

Caldecrin was previously isolated as a serum calcium-decreasing factor from the pancreas and is known to suppress receptor activator of nuclear factor-κB ligand (RANKL)-induced calcium oscillation pathways in osteoclasts. Here, we explored the effects of caldecrin on lipopolysaccharide (LPS)-Toll-like receptor-4 (TLR-4) signaling pathways in macrophages. Caldecrin inhibited the LPS-induced gene expression of pro-inflammatory cytokines and M1 macrophage polarization in mouse bone marrow macrophages and the RAW264.

[CASE REPORT: COMPLETE RESECTION OF RETROPERITONEAL CYSTIC LYMPHANGIOMA AND SURROUNDING ORGANS].

A 65-year-old man was admitted to our institution with vomiting and right flank pain. Computed tomography (CT) imaging showed a 21-cm retroperitoneal multilocular cystic tumor which had been identified four years previously. It had increased from 17 to 21 cm.

Bortezomib Eliminates Plasma Cells From a Renal Graft in Plasma Cell-Rich Acute Rejection.

Plasma cell-rich acute rejection (PCAR) and antibody-mediated rejection (ABMR), for which a standard treatment has not yet been established, are associated with poor graft survival after kidney transplantation. Here, we report a case series of 3 Japanese patients diagnosed with PCAR accompanied by ABMR. Steroid pulse therapy and rabbit antithymocyte globulin, plasma exchange, intravenous immunoglobulin, and rituximab therapies were sequentially performed in the first case.

Assessment of factors associated with mizoribine responsiveness in children with steroid-dependent nephrotic syndrome.

Background: Several immunosuppressants have been used to treat children with steroid-dependent nephrotic syndrome (SDNS). Mizoribine (MZR) is an immunosuppressant used to maintain remission in children with SDNS, although its effectiveness for treating SDNS remains controversial. Therefore, in this study, we assessed the clinical factors associated with children having SDNS who were successfully treated with MZR.

[LONG-TERM OUTCOME OF PEDIATRIC KIDNEY TRANSPLANTATION: A SINGLE-CENTER EXPERIENCES].

(Background) Long-term care is necessary for normal growth and development of pediatric recipients of kidney transplants. We report on our experience with pediatric kidney transplantation (KTx) during the past 19 years. (Methods) We retrospectively analyzed the data from 26 recipients who received KTx between 1996 and 2014 at Niigata University Hospital (one patient underwent two consecutive KTx during the designated period).

is a rare cause of peritonitis in patients on peritoneal dialysis (PD). We report a case of peritonitis due to non-typeable in a 5-year-old girl on automated PD. The patient was successfully treated with intraperitoneal cefepime and cefazolin.

Local leukocyte proliferation as a target for cyclophosphamide in the treatment of Henoch-Schönlein purpura nephritis grade VI.

Henoch-Schönlein purpura nephritis (HSPN) is one of the most common types of chronic glomerulonephritis in children; however, there have been few reports on the pathogenesis and management of grade VI HSPN. We present the case of a 6-year-old boy with grade VI HSPN accompanied by severe nephrotic syndrome and hypocomplementaemia. Immunohistological studies revealed profound glomerular accumulation of CD45- and CD68-positive inflammatory cells.

Alternatively activated macrophages in the pathogenesis of chronic kidney allograft injury.

Background: Prevention of chronic kidney allograft injury (CAI) is a major goal in improving kidney allograft survival; however, the mechanisms of CAI are not clearly understood. The current study investigated whether alternatively activated M2-type macrophages are involved in the development of CAI.

Methods: A retrospective study examined kidney allograft protocol biopsies (at 1 h and at years 1, 5, and 10--a total of 41 biopsies) obtained from 13 children undergoing transplantation between 1991 and 2008 who were diagnosed with CAI: interstitial fibrosis and tubular atrophy (IF/TA) not otherwise specified (IF/TA-NOS).

Low birthweight and premature birth are risk factors for podocytopenia and focal segmental glomerulosclerosis.

Background: Recent reports suggest that low birthweight (LBW) is a risk factor for kidney diseases, including focal segmental glomerulosclerosis (FSGS), although the underlying pathological mechanism remains unknown. Podocyte loss triggers glomerulosclerosis; however, whether FSGS in LBW children is associated with podocytopenia is unclear.

Methods: We reviewed the birthweights and gestational age of all patients who underwent renal biopsies from 1995 to 2011 at our Institute.

Serum calcium-decreasing factor, caldecrin, inhibits receptor activator of NF-κB ligand (RANKL)-mediated Ca2+ signaling and actin ring formation in mature osteoclasts via suppression of Src signaling pathway.

Osteoclasts are essential for bone dynamics and calcium homeostasis. Recently, we reported that serum calcium-decreasing factor, caldecrin, which is a secretory-type serine protease isolated from the pancreas, inhibits osteoclast differentiation by suppression of NFATc1 activity regardless of its own protease activity (Hasegawa, H., Kido, S.

Identification of alternatively activated macrophages in new-onset paediatric and adult immunoglobulin A nephropathy: potential role in mesangial matrix expansion.

Aims: New onset of the clinical symptoms of immunoglobulin A (IgA) nephropathy (IgAN) manifests with proliferative glomerular lesions in children, whereas adults exhibit mesangial matrix expansion and interstitial fibrosis. Alternatively, activated (M2) macrophages have been implicated in promoting tissue fibrosis in some settings. Therefore, the aim of this study was to investigate whether M2 macrophages are present in new-onset IgAN and if they are related to pathological differences between paediatric and adult disease.

Serum calcium-decreasing factor, caldecrin, inhibits osteoclast differentiation by suppression of NFATc1 activity.

Caldecrin/chymotrypsin C is a novel secretory-type serine protease that was originally isolated as a serum calcium-decreasing factor from the pancreas. Previously, we reported that caldecrin suppressed the bone-resorbing activity of rabbit mature osteoclasts (Tomomura, A., Yamada, H.

Contrasting effects of steroids and mizoribine on macrophage activation and glomerular lesions in rat thy-1 mesangial proliferative glomerulonephritis.

Background: Macrophages with a pro-inflammatory (M1) phenotype mediate renal injury in proliferative forms of glomerulonephritis, while alternatively activated (M2) macrophages are thought to be anti-inflammatory and promote repair. Glucocorticoids, the mainstay therapy for proliferative glomerulonephritis, can induce alternative macrophage activation in vitro, but it is unknown whether this occurs in vivo and if this is required for glucocorticoid responsiveness. In addition, clinical studies have suggested that the ability of mizoribine (MZR) to suppress steroid-resistant proliferative glomerulonephritis may operate via inhibiting pro-inflammatory macrophage activation.
