A patient with Marchiafava-Bignami disease type A transported by ambulance with impaired consciousness and malnutrition was successfully treated after early diagnosis by MRI.

Marchiafava-Bignami disease (MBD) is a very rare disorder characterized by demyelination and necrosis of the corpus callosum. A 53-year-old male was transported to the emergency room with impaired consciousness. On his arrival, he was quite emaciated.

Incidence and factors associated with newly implemented do-not-attempt-resuscitation orders among deteriorating patients after rapid response system activation: A retrospective observational study using a Japanese multicenter database.

Aim: The rapid response system (RRS) was initially aimed to improve patient outcomes. Recently, some studies have implicated that RRS might facilitate do-not-attempt-resuscitation (DNAR) orders among patients, their families, and healthcare providers. This study aimed to examine the incidence and factors independently associated with DNAR orders newly implemented after RRS activation among deteriorating patients.

The prevalence of thiamine deficiency among elderly nursing home residents: A cross-sectional study.

Background: Although thiamine deficiency (TD) can lead to Wernicke encephalopathy, the characteristics associated with TD in the elderly have not yet been clarified. We sought to clarify the frequency of TD among an institutionalized elderly population with a controlled dietary intake and to identify possible factors related to TD.

Method: We undertook a cross-sectional study of residents in three nursing homes for the elderly as of June 2020.

Management of Spontaneous Portosystemic Shunts in 231 Patients Who Underwent Living Donor Liver Transplantation: A Retrospective Study from a Single Center in Nagasaki, Japan.

BACKGROUND We have ligated spontaneous portosystemic shunts (SPSS) in living donor liver transplantation (LDLT) when a postoperative interventional radiology (IVR) approach was impossible or the intraoperative hepatopetal flow was insufficient. This retrospective study from a single center in Nagasaki, Japan aimed to investigate the management of SPSS in 231 patients who underwent LDLT between January 2006 and December 2019. MATERIAL AND METHODS SPSS were identified in 63 patients (27.

Is a decrease in activities of daily living in the elderly irreversible? A case report of Wernicke encephalopathy in home medical care.

The patient was an 83-year-old male who, after being hospitalized for 70 days for suffocation due to aspiration, was provided with home medical care (HMC) as his physical condition did not allow him to climb stairs. Wernicke encephalopathy (WE) was suspected based on his disorientation and a continued loss of appetite. This diagnosis was supported by abnormal serum thiamine and the disappearance of delirium after thiamine administration.

Characterization of radiation-induced micronuclei associated with premature senescence, and their selective removal by senolytic drug, ABT-263.

Radiotherapy is well-recognized as an efficient non-invasive remedy for cancer treatment. Since 10 Gy, a weekly total dose for conventional radiotherapy, was proven to create unreparable and residual DNA double-strand breaks (DSBs), they were found to give rise to mitotic failure, such as mitotic catastrophe, which resulted in multiple micronuclei associated with premature senescence. We demonstrated that pulverization of micronuclear DNA was caspase-dependent and triggered not ATM-dependent but DNA-PK-dependent DNA damage response, including phosphorylation of histone H2AX.

Successful removal of an accidentally swallowed press-through package sheet using a detachable snare: A case report.

Accidental swallowing of press-through package (PTP) sheets that could cause esophageal perforation is commonly encountered in emergency departments requiring early detection and removal. We report a case in which an accidentally swallowed PTP sheet was removed from the esophagus using a detachable snare after usual endoscopic methods proved ineffective. A Japanese woman in her 60s visited the emergency department with a persistent sore throat.

A case of Wernicke encephalopathy in a dementia caregiver: The need for nutritional evaluation in family caregivers.

A 63-year-old woman had started caring for her mother with dementia 6 months previously. A loss of appetite had appeared 2 months prior to her visit. Neurologically, she experienced mild unsteadiness, but she was fully conscious and had no ocular symptoms.

[Comprehensive understanding of viral diseases by field, molecular, and theoretical studies].

Viral diseases are responsible for substantial morbidity and mortality and continue to be of great concern. To ensure better control of viral infections, I have been tackling the issue as a medical doctor, an academic researcher, and a public health officer. Especially, I have studied respiratory viruses, such as the influenza virus, from the perspectives of molecular virology, theoretical modeling, and field epidemiology.

Anti-Donor Regulatory T-Cell Therapy in Adult-to-Adult Living Donor Liver Transplantation: A Case Report.

We report on the case of a 50-year-old female patient with symptomatic polycystic liver disease who underwent living donor liver transplantation (LDLT) using right liver graft from her ABO-identical husband. To achieve operational tolerance, regulatory T-cell (T-reg)-based cell therapy was applied, following the protocol introduced by Todo et al. Briefly, donor lymphocytes were collected by leukapheresis 20 days before LDLT without any adverse events, and the cells were irradiated with a dose of 30 Gy and kept frozen.

Cell competition between anaplastic thyroid cancer and normal thyroid follicular cells exerts reciprocal stress response defining tumor suppressive effects of normal epithelial tissue.

The microenvironment of an early-stage tumor, in which a small number of cancer cells is surrounded by a normal counterpart milieu, plays a crucial role in determining the fate of initiated cells. Here, we examined cell competition between anaplastic thyroid cancer cells and normal thyroid follicular cells using co-culture method. Cancer cells were grown until they formed small clusters, to which normal cells were added to create high-density co-culture condition.

A patient with spastic paralysis finally diagnosed as V180I genetic Creutzfeldt-Jakob disease 9 years after onset.

Genetic Creutzfeldt-Jakob disease (gCJD) with a mutation in codon 180 of the prion protein gene (V180I gCJD) is the most common form of gCJD in Japan, but only a few cases have been reported in Europe and the United States. It is clinically characterized by occurring in the elderly and presenting as slowly progressive dementia, although it generally shows less cerebellar and pyramidal symptoms than sporadic CJD. Here, we report a patient with V180I gCJD who initially presented with slowly progressive spastic paralysis with neither cerebrospinal fluid (CSF) nor magnetic resonance imaging (MRI) abnormalities.

Circumstances and factors of sleep-related sudden infancy deaths in Japan.

Background: Sudden unexpected death in infancy (SUDI) comprises both natural and unnatural causes of death. However, few epidemiological surveys have investigated SUDI in Japan.

Objective: This retrospective study was conducted to investigate the latest trends of circumstances and risk factors of SUDI cases in which collapse occurred during sleep.

Integrated GWAS and mRNA Microarray Analysis Identified IFNG and CD40L as the Central Upstream Regulators in Primary Biliary Cholangitis.

Genome-wide association studies (GWASs) in European and East Asian populations have identified more than 40 disease-susceptibility genes in primary biliary cholangitis (PBC). The aim of this study is to computationally identify disease pathways, upstream regulators, and therapeutic targets in PBC through integrated GWAS and messenger RNA (mRNA) microarray analysis. Disease pathways and upstream regulators were analyzed with ingenuity pathway analysis in data set 1 for GWASs (1,920 patients with PBC and 1,770 controls), which included 261 annotated genes derived from 6,760 single-nucleotide polymorphisms ( < 0.

Helical Structures of Cyclopentene-based α,α-Disubstituted α-Amino Acid Homopeptides.

The cyclopentene-based α,α-disubstituted α-amino acid Acc and its homopeptides, up to nonapeptides, were synthesized. The side-chain cyclopentene was expected to become symmetric, the C-carbon to be puckered, and other C, C, C, C-carbons to be coplanar. As expected, side-chain cyclopentene conformations became symmetric and C-carbons were puckered.

Antineutrophilic cytoplasmic antibody-associated vasculitis with hypocomplementemia has a higher incidence of serious organ damage and a poor prognosis.

A relationship between antineutrophilic cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and complement has been shown, and complement has an important role in the pathogenesis of AAV. The clinical characteristics of AAV with hypocomplementemia still remain unclear.We conducted an observational study of 81 patients with AAV (median onset age 71 years; 58% female).

Frequency of elevated biomarkers in patients with cryptogenic hepatocellular carcinoma.

Background: The incidence of hepatocellular carcinoma (HCC) continues to increase in Japan, but the clinical characteristics of Japanese patients with HCC have not been well described. The aim of this study was to determine the frequencies and utilities of elevated a-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP) levels as biomarkers in cryptogenic HCC.

Material/methods: A total of 2638 patients with HCC diagnosed between 1999 and 2010 in the Nagasaki Association Study of Liver (NASLD) were recruited for this study.

Gentle touch activates the anterior prefrontal cortex: an NIRS study.

Gentle touching of the hand activates emotion- and reward-related regions of the brain. The present study investigated activation of the prefrontal cortex by gentle sweeps of the palm or forearm with three materials (wood, velvet, paintbrush) using near-infrared spectroscopy (NIRS). Sweeps of the left palm with a sensuous velvet fabric increased the oxy-hemoglobin (oxy-Hb) concentration in the frontal-polar cortex (FPC) and a part of the orbitofrontal cortex (OFC), compared to a neutral touch produced by rounded wood.
