Patients And Methods: This single-center retrospective cohort study included 548 patients who underwent gastrectomy for primary gastric adenocarcinoma from January 2011 to December 2019.

[Gastric Ulcer Caused by Contact with a Bumper Type Gastrostomy Tube in Amyotrophic Lateral Sclerosis: A Case Report].

An 86-year-old man was diagnosed with bulbar type of amyotrophic lateral sclerosis (ALS). He underwent a bumper-tube type of gastrostomy due to dysphagia 16 months after the onset of ALS. Twenty months after the onset, he developed dyspnea due to anemia.

Comprehensive complication index as a prognostic factor in minimally invasive esophagectomy for esophageal squamous cell carcinoma.

Background: Postoperative complications affect long-term prognosis in patients with esophageal squamous cell carcinoma (ESCC). Although a comprehensive estimator can predict long-term prognosis, the Clavien-Dindo classification system, a widely used approach to evaluate complications, assesses each complication individually. We aimed to clarify the utility of the comprehensive complication index (CCI) on predicting the overall survival (OS) of patients with ESCC following minimally invasive esophagectomy (MIE).

Quantitative Comparison of Surgical Device Usage in Laparoscopic Gastrectomy Between Surgeons' Skill Levels: an Automated Analysis Using a Neural Network.

Background: Whether surgical device usage in laparoscopic gastrectomy differs with respect to operator's skill levels is unknown. Further, device usage analysis using artificial intelligence has not been reported to date. Herein, we compared the patterns of surgical device usage during laparoscopic gastrectomy for gastric cancer among surgeons at different skill levels.

Persistent intrathecal interleukin-8 production in a patient with SARS-CoV-2-related encephalopathy presenting aphasia: a case report.

Background: Neurological manifestations of coronavirus disease 2019 (COVID-19) are increasingly recognized and include encephalopathy, although direct infection of the brain by SARS-CoV-2 remains controversial. We herein report the clinical course and cytokine profiles of a patient with severe SARS-CoV-2-related encephalopathy presenting aphasia.

Case Presentation: An 81-year-old man developed acute consciousness disturbance and status epileptics several days after SARS-CoV-2 infection.

Comparison of laparoscopic gastrectomy with 3-D/HD and 2-D/4 K camera system for gastric cancer: a prospective randomized control study.

Purpose: We conducted a prospective clinical control study to identify the best imaging technology among three-dimensional (3-D) high-definition (HD) stereovision and two-dimensional (2-D) ultra-high-resolution (4 K) technology and confirm their effects on surgical outcomes of laparoscopic gastrectomy for gastric cancer.

Methods: From April 2018 to August 2019, 50 patients were randomly classified into two groups based on the imaging technology (3-D/HD group = 25, 2-D/4 K = 25). After excluding eight patients based on laparoscopic findings, 42 patients were analyzed (3-D/HD group = 21, 2-D/4 K = 21).

Long-term preservation of pharyngeal swallowing function in MM2-cortical-type sporadic Creutzfeldt-Jakob disease.

Swallowing function in long-term survivors of Creutzfeldt-Jakob disease (CJD) has not been elucidated. Herein, we report a patient with MM2-cortical-type sporadic CJD (MM2C-type sCJD) with long-term preservation of pharyngeal swallowing function using videofluoroscopic (VF) examination of swallowing. A 55-year-old woman was admitted to hospital because of dyscalculia and memory disturbance 3 years after the onset of these symptoms.

Laparoscopic sigmoidectomy with splenic flexure mobilization for colon cancer in situs inversus totalis: Preoperative assessment and preparation.

Situs inversus totalis (SIT) is a rare condition in which the internal organ's position is a mirror image of normal anatomy. Although several investigators reported laparoscopic surgery for colorectal cancer in patients with SIT, it is considered difficult even for an experienced surgeon because of the mirror position. We show a case report of laparoscopic sigmoidectomy with the splenic flexure mobilization (SFM) procedure in SIT.

Three-dimensional visualization system is one of the factors that improve short-term outcomes after minimally invasive esophagectomy.

Purpose: Minimally invasive esophagectomy (MIE) has been increasingly used, but many reports have stated that recurrent laryngeal nerve (RLN) palsy after MIE is a major complication associated with postoperative pneumonia. Prevention of RLN palsy clearly has been a challenging task. The study aim was to determine if a three-dimensional (3-D) stereoscopic vision system can reduce the RLN palsy rate after MIE.

Autoimmune Glial Fibrillary Acidic Protein Astrocytopathy Presenting with Slowly Progressive Myelitis and Longitudinally Extensive Spinal Cord Lesions.

We report a 65-year-old man with autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) who presented with gait disturbance that he had experienced for approximately half a year. On neurological examination, he displayed spastic paraplegia and autonomic dysfunctions including dysuria and constipation. Spinal cord magnetic resonance imaging showed longitudinally extensive spinal cord lesions (LESCLs) extending from the cervical to the thoracic cords.

A Case of Crossed Logopenic Primary Progressive Aphasia in a Dextral Patient with Underlying Frontotemporal Dementia.

A 61-year-old dextral woman was admitted to the hospital with difficulty finding words. Neurological examinations confirmed that her speech was affected by frequent pauses and occasional phonological paraphasia without cognitive deficits. We detected atrophy, hypoperfusion, and hypometabolism in the right perisylvian and parietal regions, expanding to the right anterior temporal lobes and right inferior frontal gyrus (opercular region) by magnetic resonance imaging, single-photon emission computed tomography, and fluorodexyglucose-positron emission tomography (PET), respectively.

Drug-induced Pressure Ulcers in a Middle-aged Patient with Early-stage Parkinson's Disease.

Drug-induced pressure ulcer (DIPU), which is a newly recognized adverse drug reaction, is associated with the administration of psychiatric drugs in geriatric patients with dementia. The notification of the causative drugs is crucial to the treatment of DIPU. We herein report the case of a 56-year-old woman with early-stage Parkinson's disease who developed DIPUs after starting olanzapine treatment for depressive symptoms.

Durability-enhanced two-dimensional hole gas of C-H diamond surface for complementary power inverter applications.

Complementary power field effect transistors (FETs) based on wide bandgap materials not only provide high-voltage switching capability with the reduction of on-resistance and switching losses, but also enable a smart inverter system by the dramatic simplification of external circuits. However, p-channel power FETs with equivalent performance to those of n-channel FETs are not obtained in any wide bandgap material other than diamond. Here we show that a breakdown voltage of more than 1600 V has been obtained in a diamond metal-oxide-semiconductor (MOS) FET with a p-channel based on a two-dimensional hole gas (2DHG).

[Factors affecting adherence of breast cancer patients to adjuvant hormonal therapy and validation of the evaluation method].

Background: The long-term use of hormonal therapy is important for the treatment of patients with breast cancer. Therefore, we evaluated the methods used for measuring adherence and examined factors that influence compliance. Our goal was to improve overall adherence to the treatment.

Analysis of interchannel crosstalk in multimode parallel optical waveguides using the beam propagation method.

We theoretically analyze the origin of inter-channel crosstalk in densely aligned multimode parallel optical waveguides for on-board interconnects using the Beam Propagation Method. In this paper, we demonstrate that the inter-channel crosstalk due to mode coupling is very low in graded-index (GI) circular-core waveguides because the propagation constants of the propagating modes are discrete. Additionally, it is also found that the waveguides with GI-type circular cores is sensitive to the optical confinement in the cladding: low-power cladding modes largely decrease the mode conversion.

Effect of nematode Trichinella infection on glucose tolerance and status of macrophage in obese mice.

We investigated the effect of Trichinella infection on glucose tolerance and (pro- or anti-inflammatory) macrophage status in adipose tissue. Ob/ob mice and high fat-fed mice (obesity model) and C57/BL mice (control mice) were orally infected with (infected group) or without (uninfected group) 400 Trichinella per mouse. Four weeks later, the mice were subjected to investigation, which showed that fasting plasma glucose levels decreased in the infected group of C57/BL and ob/ob mice.
