Clinical Outcomes of Direct Oral Anticoagulants and Warfarin in Japanese Patients with Atrial Fibrillation Aged ≥ 85 Years: A Single-Center Observational Study.

Background: Increasing age is associated with an increase in stroke in patients with nonvalvular atrial fibrillation (NVAF). Elderly patients have several comorbidities and increased bleeding risk.

Objective: The aim of this study was to evaluate the clinical outcomes of Japanese patients with NVAF aged ≥ 85 years who were treated with direct oral anticoagulants (DOACs) or warfarin.

BC-Box Motif in SOCS6 Induces Differentiation of Epidermal Stem Cells into GABAnergic Neurons.

The BC-box motif in suppressor of cytokine signaling 6 (SOCS6) promotes the neuronal differentiation of somatic stem cells, including epidermal stem cells. SOCS6 protein belongs to the group of SOCS proteins and inhibits cytokine signaling. Here we showed that epidermal stem cells were induced to differentiate into GABAnergic neurons by the intracellular delivery of a peptide composed of the amino-acid sequences encoded by the BC-box motif in SOCS6 protein.

The protective effect of G9-1 against mucus degradation by following small intestine injury caused by a proton pump inhibitor and aspirin.

Proton pump inhibitors (PPIs) can alleviate upper gastrointestinal injury but paradoxically exacerbate aspirin (ASA)-induced small intestine injury. In this study, our goal was to simulate this exacerbation by developing an appropriate animal model, which may help in establishing treatments. : Male mice were fed a 60% fructose diet for 9 weeks, then administered 200 mg/kg ASA 3 h before sacrifice.

Comparing the effectiveness of magnesium oxide and naldemedine in preventing opioid-induced constipation: a proof of concept, single institutional, two arm, open-label, phase II, randomized controlled trial: the MAGNET study.

Background: Patients taking opioids are known to develop opioid-induced constipation (OIC), which reduces their quality of life. The aim of this study is to compare magnesium oxide with naldemedine and determine which is more effective in preventing OIC.

Methods: This proof-of-concept, prospective, randomized controlled trial commenced in Japan in March 2018.

Metabolomic/lipidomic-based analysis of plasma to diagnose hepatocellular ballooning in patients with non-alcoholic fatty liver disease: A multicenter study.

Aim: Liver biopsy is still required for the diagnosis of hepatocellular ballooning and inflammation, which are important histological features of non-alcoholic steatohepatitis. We undertook this multicenter, cross-sectional study to identify novel blood markers for the diagnosis of hepatocellular ballooning.

Methods: We enrolled 176 patients, of whom 132 were proven by liver biopsy as having non-alcoholic fatty liver disease (NAFLD) and classified as non-ballooning (ballooning grade 0) (n = 83) or ballooning (ballooning grade 1 and 2) (n = 49) by a central pathology review.

Histopathology of castration-resistant prostate cancer confirms changes in bone metastasis during radium-223 treatment: A case report.

Radium-223 is used for treating castration-resistant prostate cancer with bone metastases. Here, we report the case of a 76-year-old man diagnosed with castration-resistant prostate cancer with bone metastases who was started on radium-223. Although the patient ultimately died from causes unrelated to the treatment before starting the third treatment course, we observed that radium-223 was more effective in areas closer to the bone cortex than in deeper tumor regions.

Role of VHL-JAK-STAT signaling pathway in central nervous system hemangioblastoma associated with von Hippel-Lindau disease.

Introduction: Central nervous system hemangioblastoma is a benign tumor associated with or without von Hippel-Lindau (VHL) disease which is an autosomal dominant hereditary disease that results from a germline mutation in the VHL gene. A main axis of signaling pathways in central nervous system hemangioblastoma is VHL-HIF signaling pathway. Here, we propose an alternative VHL-JAK-STAT signaling pathway in hemangioblastoma and discuss the role.

Cefaclor as a first-line treatment for acute uncomplicated cystitis: a retrospective single-center study.

Background: Wide-spectrum antibiotics have been favored to treat acute uncomplicated cystitis (AUC) for a long time, leading to the emergence of multi-drug resistant bacteria. We hypothesize that narrow-spectrum antibiotics might mitigate the issue and aim to investigate the clinical efficacy of cefaclor in patients with AUC.

Methods: We retrospectively reviewed the clinical data of female outpatients with AUC treated with cefaclor and evaluated the safety and clinical efficacy.

Predictors of the Response to an Epidural Blood Patch in Patients with Spinal Leakage of Cerebrospinal Fluid.

Background And Purpose: An epidural blood patch (EBP) is a highly effective therapy for spinal cerebrospinal fluid (CSF) leakage. However, the factors predicting the response to an EBP have not been fully elucidated. The aim of this study was to elucidate factors predicting the response to an EBP.

The Effect of Grandmothers' Presence on the Provision of Multidisciplinary Perinatal Support for Pregnant and Postpartum Women with Psychosocial Problems.

Background: Pregnant and postpartum women with psychosocial problems are prone to face limited or absent perinatal functional support from biological grandmothers due to familial dysfunction. The study aimed to investigate whether the involvement and presence of biological maternal grandmothers providing practical support for their pre/postnatal daughters (ie, pregnant women) during the perinatal period may influence the number of support services provided by multidisciplinary agencies, including child consultation centers and municipal offices.

Participants And Methods: This is a retrospective cohort study based on the medical records of all pregnant women with psychosocial problems that visited, gave birth, and received intervention from the hospital-based child protection unit at the Chiba University Hospital between February 2018 to March 2019.

Synergistic and Pharmacotherapeutic Effects of Gemcitabine and Cisplatin Combined Administration on Biliary Tract Cancer Cell Lines.

Gemcitabine (GEM) and cisplatin (CDDP) combination therapy (GC) is the standard chemotherapy for advanced biliary tract cancer (BTC); however, its pharmacotherapeutic efficacy remains unclear. To investigate the effects of GC, we selected 11 from 17 BTC cell lines, according to their GEM sensitivity, to be assessed using the MTS assay. The presence of synergistic effects of GC was determined using the Bliss additivism model (BM) and the combination index (CI) at a GEM:CDDP molar ratio of 7:1; this ratio was based on the respective human renal clearances of the two drugs.

Autotaxin is a valuable biomarker for the prediction of liver fibrosis in patients with non-alcoholic fatty liver disease.

Aim: We investigated the characteristics of serum autotaxin (ATX) and its diagnostic performance for liver fibrosis in a large cohort of patients with non-alcoholic fatty liver disease (NAFLD).

Methods: We compared the usefulness of ATX and other fibrosis markers in 307 biopsy-confirmed NAFLD patients. In addition, in 145 participants with NAFLD, we compared the diagnostic performance of ATX with that of non-invasive imaging methods (vibration-controlled transient elastography and magnetic resonance elastography [MRE]).

Assessment of 10-year changes in liver stiffness using vibration-controlled transient elastography in non-alcoholic fatty liver disease.

Aim: Although liver biopsy is the gold standard for the diagnosis and staging of non-alcoholic fatty liver disease (NAFLD), repeated assessment of patients' liver tissue conditions are impractical. We assessed the 10-year changes in liver stiffness measurements (LSM) utilizing vibration-controlled transient elastography in NAFLD patients.

Methods: From January 2006 to September 2007, LSM was carried out for 97 biopsy-proven NAFLD patients.

Comparison of anti-inflammatory effects of rivaroxaban vs. dabigatran in patients with non-valvular atrial fibrillation (RIVAL-AF study): multicenter randomized study.

Some experimental studies have shown that direct oral anticoagulants (DOACs) have anti-inflammatory effects. However, the interval changes in inflammatory markers in patients with non-valvular atrial fibrillation (AF) who receive DOACs remain unknown. Between July 2013 and April 2014, a total of 187 AF patients randomly assigned to receive rivaroxaban (n = 91) or dabigatran (n = 96) were assessed for eligibility.

Distribution of liver stiffness in non-alcoholic fatty liver disease with higher fibrosis-4 index than low cut-off index.

Background And Aim: In the condition of high prevalence of non-alcoholic fatty liver disease (NAFLD), a new diagnostic algorithm to efficiently identify NAFLD patients with significant fibrosis is urgently required. We evaluated the predictive ability of the fibrosis-4 index (FIB-4 index) for significant liver fibrosis (F ≥ 2) in a cohort of Japanese patients with NAFLD.

Methods: We prospectively calculated the FIB-4 index in patients who were incidentally diagnosed as fatty liver in medical checkups and then conducted liver stiffness measurement by vibration-controlled transient elastography (VCTE) only in patients in whom the FIB-4 index was more than the low cut-off index (> 1.

Histological Effects of the Combined Administration of Eldecalcitol and a Parathyroid Hormone in the Metaphyseal Trabeculae of Ovariectomized Rats.

Intermittent administration of human parathyroid hormone (1-34) (hPTH(1-34)) promotes anabolic action in bone by stimulating bone remodeling, while eldecalcitol, an analog of active vitamin D3, suppresses osteoclastic bone resorption, and forms new bone by minimodeling. We have examined the biological effects of combined administration of eldecalcitol and hPTH(1-34) on 9-week-old Wistar rats that underwent an ovariectomy (OVX) or Sham operation. They were divided into a Sham group, OVX with vehicle (OVX group), OVX with 10 µg/kg/day of hPTH(1-34) (PTH group), OVX with 20 ng/kg/day of eldecalcitol (eldecalcitol group) or OVX with 10 μg/kg/day of hPTH(1-34), and 20 ng/kg/day of eldecalcitol (combined group) for 4 or 8 weeks.

Identification of differentially methylated region (DMR) networks associated with progression of nonalcoholic fatty liver disease.

The progression of nonalcoholic fatty liver disease (NAFLD) is affected by epigenetics. We performed differentially methylated region (DMR) and co-methylation analyses to identify DMR networks associated with the progression of NAFLD. DMRs displaying differences in multiple consecutive differentially methylated CpGs between mild and advanced NAFLD were extracted.

VHL-Associated Optic Nerve Hemangioblastoma Treated with Stereotactic Radiosurgery.

Central nervous system hemangioblastomas are generally restricted to the cerebellum, spinal cord, and brainstem. Supratentorial hemangioblastomas are uncommon, and optic nerve hemangioblastomas are extremely rare, with fewer than 25 reports including this case. In this report, we present the case of a 36-year-old woman with von Hippel-Lindau (VHL) disease who presented with progressive diminution of vision in the left eye due to a retrobulbar optic nerve hemangioblastoma.

Pretreatment monocyte counts and neutrophil counts predict the risk for febrile neutropenia in patients undergoing TPF chemotherapy for head and neck squamous cell carcinoma.

Background: Febrile neutropenia (FN) is the most serious hematologic toxicity of systemic chemotherapy. However, accurate prediction of FN development has been difficult because the risk varies largely depending on the chemotherapy regimen and various individual factors.

Methods: We retrospectively analyzed diverse clinical factors including pretreatment hematological parameters to clarify the reliable predictors of FN development during chemotherapy with a docetaxel, cisplatin, and fluorouracil (TPF) regimen in patients with head and neck squamous cell carcinoma.

Novel clinical features of nonconvulsive status epilepticus.

Nonconvulsive status epilepticus (NCSE) has rapidly expanded from classical features such as staring, repetitive blinking, chewing, swallowing, and automatism to include coma, prolonged apnea, cardiac arrest, dementia, and higher brain dysfunction, which were demonstrated mainly after the 2000s by us and other groups. This review details novel clinical features of NCSE as a manifestation of epilepsy, but one that is underdiagnosed, with the best available evidence. Also, we describe the new concept of epilepsy-related organ dysfunction (Epi-ROD) and a novel electrode and headset which enables prompt electroencephalography.

Comparison of Airway Measurements for Tracheobronchial Stenosis Between Stereoscopic Bronchoscope and MD-CT.

Background: Stereoscopic bronchoscopy is a new diagnostic tool to measure the diameter and cross-sectional area of the airway. The stereoscopic bronchoscope, which operates the same as a standard bronchoscope, utilizes 2 lenses to measure the airway using the principles of triangulation. Furthermore, the stereoscopic bronchoscope has the capability to measure the size of the airway during intervention in real-time, including variable stenosis.

Does Treatment of Impaired Glucose Tolerance Improve Cardiovascular Outcomes in Patients with Previous Myocardial Infarction?

Purpose: We evaluated the effects of an alpha-glucosidase inhibitor, voglibose, on cardiovascular events in patients with a previous myocardial infarction (MI) and impaired glucose tolerance (IGT).

Methods: This prospective, randomized, open, blinded-endpoint study was conducted in 112 hospitals and clinics in Japan in 3000 subjects with both previous MI and IGT receiving voglibose (0.6 mg/day, n = 424) or no drugs (n = 435) for 2 years.

The Efficacy of High-Frequency Repetitive Transcranial Magnetic Stimulation for Improving Apathy in Chronic Stroke Patients.

Although repetitive transcranial magnetic stimulation (rTMS) for hemiparesis is beneficial, so far no study has examined the usefulness of rTMS for apathy. Thirteen patients with chronic stroke were assigned randomly to 2 groups: rTMS group (n = 7) and sham stimulation group (n = 6). The patients received 5 sessions of either high-frequency rTMS over the region spanning from the dorsal anterior cingulate cortex (dACC) to medial prefrontal cortex (mPFC) or sham stimulation for 5 days.
