Mechanisms of mineralocorticoid receptor-associated hypertension in diabetes mellitus: the role of O-GlcNAc modification.

This study investigated the mechanism underlying the beneficial effects of mineralocorticoid receptor (MR) antagonists in patients with resistant hypertension and diabetic nephropathy by examining post-translational modification of the MR by O-linked-N-acetylglucosamine (O-GlcNAc), which is strongly associated with type 2 diabetes. Coimmunoprecipitation assays in HEK293T cells showed that MR is a target of O-GlcNAc modification (O-GlcNAcylation). The expression levels and transcriptional activities of the receptor increased in parallel with its O-GlcNAcylation under high-glucose conditions.

Laparoscopic repair of diaphragmatic hernia associating with radiofrequency ablation for hepatocellular carcinoma: A case report.

Background: Radiofrequency ablation (RFA) is an effective treatment for early-stage hepatocellular carcinoma (HCC). Although RFA is a relatively safe technique compared with surgery, several complications have been reported to be following/accompanying this treatment. Delayed diaphragmatic hernia caused by RFA is rare; however, the best surgical approach for its treatment is uncertain.

Novel external oblique muscle plane block for blockade of the lateral abdominal wall: a pilot study on volunteers.

Purpose: No reports have described techniques to efficiently anesthetize the lateral cutaneous branches of the entire abdomen. The aim of this study was to investigate an effective procedure for blocking the lateral cutaneous branches in the abdominal region. We sought to describe the sensory distribution of the previously described thoracoabdominal nerve block through perichondrial approach (TAPA) and the novel costal and lateral external oblique muscle plane (EXOP) blocks in healthy volunteers.

Surface CD3-negative monomorphic epitheliotropic intestinal T-cell lymphoma.

Intestinal T/NK-cell lymphomas include enteropathy-associated T-cell lymphoma (EATL), monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), indolent T-cell lymphoproliferative disorders of the GI tract (ITCLPD), extranodal NK/T-cell lymphoma, nasal type (ENKTL), and intestinal T-cell lymphoma NOS (ITCL-NOS). Here we describe a case of surface CD3-negative MEITL. A 63-year-old Japanese female had a tumor located in the conglomerated ileum, which formed multiple mass lesions.

Implications of QRS Prolongation in Patients With Atrial Fibrillation (from a Multicenter Outpatient Registry).

Patients with atrial fibrillation (AF) at the highest risk of progression to heart failure (HF) need to be identified. We investigated whether QRS duration can stratify patients with AF at risk for poor clinical outcomes, including health-related quality of life (HR-QoL). We analyzed data from a multicenter registry-based cohort study of patients with AF.

Long-term course of early onset developmental and epileptic encephalopathy associated with 2q24.3 microduplication.

Copy number variations (CNVs) have been related to developmental and epileptic encephalopathy (DEE). The 2q24.3 region includes a cluster of genes for voltage-gated sodium channels (SCN) and CNVs in this region cause DEE.

Adenocarcinoma or early-stage cervical cancer is a risk factor for preterm delivery after cervical conization: a multicenter observational study.

Objective: Pregnancy after conization is associated with a high risk of preterm delivery. However, because risk factors for preterm delivery after conization remain unknown, we conducted a multicenter observational study to investigate risk factors associated with preterm delivery.

Methods: We selected patients who had previously undergone conization and reviewed medical records from 18 hospitals in cooperation with Keio University School of Medicine between January 2013 and December 2019.

Study protocol and baseline characteristics of newly induced dialysis patients: a prospective multi-center cohort study with a biological sample bank, the Ibaraki Dialysis Initiation Cohort (iDIC) study.

Background: Patients with end-stage kidney disease (ESKD) face higher risks of life-threatening events including cardiovascular disease. Various risk factors are identified as agents influencing the life prognosis of ESKD patients. Herein, we evaluated the risk factors related to the outcomes of Japanese patients with dialysis induction.

Myocardial T-Lymphocytes as a Prognostic Risk-Stratifying Marker of Dilated Cardiomyopathy - Results of the Multicenter Registry to Investigate Inflammatory Cell Infiltration in Dilated Cardiomyopathy in Tissues of Endomyocardial Biopsy (INDICATE Study).

Background: Dilated cardiomyopathy (DCM) associated with inflammation is diagnosed by endomyocardial biopsy; patients with this have a poorer prognosis than patients without inflammation. To date, standard diagnostic criteria have not been established.

Methods and results: This study analyzed clinical records and endomyocardial biopsy samples of 261 patients with DCM (201 males, median left ventricular ejection fraction; 28%) from 8 institutions in a multicenter retrospective study.

[A case of gastric mixed neuroendocrine-non-neuroendocrine neoplasm that developed five years after pancreatic neuroendocrine tumor treatment].

We present a case of 63-year-old male patient who underwent subtotal stomach-preserving pancreaticoduodenectomy for pancreatic neuroendocrine tumor (NET) G2. He had been followed up for three years and had no signs of recurrence postoperatively. Five years after surgery, he had abdominal pain.

Successful Tepotinib Challenge After Capmatinib-Induced Interstitial Lung Disease in a Patient With Lung Adenocarcinoma Harboring Exon 14 Skipping Mutation: Case Report.

MET tyrosine kinase inhibitors, capmatinib and tepotinib, have been recently introduced for the treatment of advanced NSCLC with exon 14 skipping mutations. Although interstitial lung disease (ILD) induced by these drugs is reported, its optimal management and whether they can be rechallenged remain unclear. We report the first successful case of tepotinib treatment after capmatinib-induced ILD.

Epstein-Barr viral corneal stromal keratitis occurring during rheumatoid arthritis treatment: a case report.

Background: A case of Epstein-Barr viral (EBV) corneal stromal keratitis during rheumatoid arthritis (RA) treatment is presented.

Case Presentation: A 74-year-old female undergoing RA treatment was previously treated for bacterial corneal ulcer and herpetic keratitis and healed with antibiotic eye drops and topical anti-herpes ointment. At the first visit to our hospital, she presented with findings of monocular posterior interstitial keratitis with neovascularization mostly located in the inferior cornea with a corneal epithelial defect.

Identification of diverticular bleeding needs early colonoscopy rather than preparation.

 When patients present with acute colonic diverticulum bleeding (CDB), a colonoscopy is performed to identify stigmata of recent hemorrhage (SRH), but valuable time can be lost in bowel preparation. This study retrospectively examined groups of patients who either had a standard pre-colonoscopy regimen or no preparation. This study compared data from 433 patients who either followed a lengthy regimen of bowel preparation (prepared group, 266 patients) or had no preparation (unprepared group, 60 patients).

Disappearance of recurrent thymic epithelial tumor following corticosteroid and cyclosporine treatment: A case report.

Thymic epithelial tumors (TETs) are considered orphan neoplasms, and treatment options for recurrent or metastatic stages are limited. Here, we have reported a case of recurrent TET that showed complete remission after receiving high-dose corticosteroids followed by low-dose corticosteroids and cyclosporine. No recurrence was observed for the next 2 years.

Standard therapy-resistant small cell lung cancer showing dynamic transition of neuroendocrine fate during the cancer trajectory: A case report.

While small cell lung cancer (SCLC) has been treated as a single disease historically, recent studies have suggested that SCLC can be classified into molecular subtypes based on the expression of lineage transcription factors such as achaete-scute homolog 1 (ASCL1), neurogenic differentiation factor 1 (NEUROD1), POU domain class 2 transcription factor 3 (POU2F3) and transcriptional coactivator YAP1 (YAP1). These transcription factor-based subtypes may be specifically targeted in therapy, and recent studies have suggested that the SCLC subtypes represent different stages of dynamic evolution of SCLC rather than independent diseases. Nevertheless, evidence of shift in neuroendocrine differentiation during SCLC evolution has been lacking in the clinical setting.

Clinical Utility of the Electrocardiographic P-Wave Axis in Patients with Chronic Obstructive Pulmonary Disease.
