Subtotal colectomy for refractory ulcerative colitis with COVID-19 infection; a first case report in Japan.

We report a 60-year-old male who was transferred to our hospital for the operation because of refractory ulcerative colitis (UC). He was diagnosed to be infected with COVID-19 for SARS-CoV-2 PCR test positive at the time of transfer. We determined emergency operation because his general condition was poor such as malnutrition and ADL decline due to exacerbation of UC and air embolization by central venous catheter removal.

The U-shaped association of serum iron level with disease severity in adult hospitalized patients with COVID-19.

Coronavirus disease 2019 (COVID-19) is an emerging infectious disease that leads to severe respiratory failure (RF). It is known that host exposure to viral infection triggers an iron-lowering response to mitigate pathogenic load and tissue damage. However, the association between host iron-lowering response and COVID-19 severity is not clear.

High postoperative neutrophil-lymphocyte ratio and low preoperative lymphocyte-monocyte ratio predict poor prognosis in gastric cancer patients receiving gastrectomy with positive lavage cytology: a retrospective cohort study.

Background: Long-term outcomes in gastric cancer patients with positive lavage cytology (CY1) are generally poor. This multi-institutional retrospective cohort study aims to evaluate the clinical significance of the neutrophil-lymphocyte ratio (NLR) and the lymphocyte-monocyte ratio (LMR) in CY1 gastric cancer patients.

Methods: A total of 121 CY1 gastric cancer patients without other non-curative factors, who underwent macroscopically curative resection, were enrolled in this study.

A Hepatitis C Virus-Associated Decompensated Cirrhotic Patient Who Showed the Disappearance of Hepatic Encephalopathy, Ascites, and Pleural Effusion by Antiviral Therapy with Sofosbuvir/Velpatasvir.

Oral direct-acting antivirals (DAAs) are the main therapy for hepatitis C virus (HCV)-associated liver disease in Japan. Moreover, many DAAs include an indication for compensated liver cirrhosis. However, patients with decompensated HCV-associated cirrhosis have hitherto not been indicated for therapy with DAAs.

Highly specific monoclonal antibodies and epitope identification against SARS-CoV-2 nucleocapsid protein for antigen detection tests.

The ongoing coronavirus disease 2019 (COVID-19) pandemic is a major global public health concern. Although rapid point-of-care testing for detecting viral antigen is important for management of the outbreak, the current antigen tests are less sensitive than nucleic acid testing. In our current study, we produce monoclonal antibodies (mAbs) that exclusively react with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and exhibit no cross-reactivity with other human coronaviruses, including SARS-CoV.

Photoacoustic lymphangiography before and after lymphaticovenular anastomosis.

Background: Lymphaticovenular anastomosis (LVA) is a minimally invasive surgical procedure used to treat lymphedema. Volumetric measurements and quality-of-life assessments are often performed to assess the effectiveness of LVA, but there is no method that provides information regarding postoperative morphological changes in lymphatic vessels and veins after LVA. Photoacoustic lymphangiography (PAL) is an optical imaging technique that visualizes the distribution of light-absorbing molecules, such as hemoglobin or indocyanine green (ICG), and provides three-dimensional images of superficial lymphatic vessels and the venous system simultaneously.

Dual-innervated multivector muscle transfer using two superficial subslips of the serratus anterior muscle for long-standing facial paralysis.

Recent reports have described several cases of double muscle transfers to restore natural, symmetrical smiles in patients with long-standing facial paralysis. However, these complex procedures sometimes result in cheek bulkiness owing to the double muscle transfer. We present the case of a 67-year-old woman with long-standing facial paralysis, who underwent two-stage facial reanimation using two superficial subslips of the serratus anterior muscle innervated by the masseteric and contralateral facial nerves via a sural nerve graft.

Clinicopathological and molecular characteristics of endometrial neuroendocrine carcinomas reveal preexisting endometrial carcinoma origin.

Endometrial neuroendocrine carcinoma is a rare disease with unknown clinicopathological and molecular characteristics. Therefore, we conducted the present study to elucidate the clinicopathological and molecular characteristics of endometrial neuroendocrine carcinoma, as compared to conventional endometrial carcinoma, and to determine the origin of the former. We analyzed 22 endometrial neuroendocrine carcinomas and 22 conventional endometrial neoplasia cases with respect to clinical, histological and genetic features.

Laparoscopic surgery for massive ovarian edema during pregnancy: A case report.

Massive ovarian edema (MOE) is a rare non-neoplastic clinicopathologic disease that is characterized by stromal edema and is caused by the partial or intermittent obstruction of venous and lymphatic drainage. The literature on MOE contains approximately 200 cases, but only 12 cases of MOE during pregnancy have been reported to date. We report a case of MOE at 22 weeks of gestation that was diagnosed preoperatively, and the patient underwent laparoscopic surgery.

Single Versus Multiple Daily Dosing Regimens of Psychotropic Drugs for Psychiatric Disorders: A Systematic Review and Meta-Analysis.

Objective: To compare efficacy and safety of single daily dosing (Single-DD) vs multiple daily dosing (Multiple-DD) regimens of psychotropic drugs, the authors conducted a systematic review and meta-analysis.

Data Sources: A systematic literature search of MEDLINE and Embase was conducted with keywords related to dosing regimens and psychotropic drugs (last search: December 30, 2019).

Study Selection: Randomized controlled trials comparing clinical outcomes between Single-DD and Multiple-DD of the same formulation of the same psychotropic drugs in patients with psychiatric disorders were included.

Postoperative Survival in Colitis-associated Colorectal Cancer With Ulcerative Colitis in Japan: A Multicenter Analysis.

Background/aim: The aim of the study was to analyze the postoperative survival of colitis-associated colorectal cancer (CAC) with ulcerative colitis (UC), and the risk factors affecting it.

Patients And Methods: A questionnaire including postoperative survival was sent to 88 hospitals that reported CAC patients in the literature up until January, 2006 and to members of the Research Group of Intractable Inflammatory Bowel Disease.

Results: The 5-year postoperative overall survival (OS) of 170 CAC patients was 74.

Internet-based behavioural activation to improve depressive symptoms and prevent child abuse in postnatal women (SmartMama): a protocol for a pragmatic randomized controlled trial.

Background: Child abuse and postnatal depression are two public health problems that often co-occur, with rates of childhood maltreatment highest during the first year of life. Internet-based behavioural activation (iBA) therapy has demonstrated its efficacy for improving postnatal depression. No study has examined whether the iBA program is also effective at preventing child abuse.

Identification of B.1.346 Lineage of SARS-CoV-2 in Japan: Genomic Evidence of Re-entry of Clade 20C.

SARS-CoV-2 whole-genome sequencing of samples from COVID-19 patients is useful for informing infection control. Datasets of these genomes assembled from multiple hospitals can give critical clues to regional or national trends in infection. Herein, we report a lineage summary based on data collected from hospitals located in the Tokyo metropolitan area.

Clinicopathological and prognostic evaluations of anorectal cancer after fecal diversion for patients with Crohn's disease.

Purpose: Colorectum diversion with a proximal stoma is often the preferred surgical approach in patients with Crohn's disease-related anorectal lesions or refractory colitis. To date, few studies have assessed the incidence and prognosis of cancer in the diverted anorectal segments. This study aimed to evaluate the clinical characteristics and prognosis of anorectal cancer associated with Crohn's disease following fecal diversion.

Utility of gastric ultrasound in evaluating status in a child.

Although rare, the aspiration of gastric contents can lead to significant morbidity or even mortality in pediatric patients receiving anesthetic care. For elective cases, routine preoperative practices include the use of standard times to decrease the risk of aspiration. However, patients may fail to adhere to provided NPO guidelines or other patient factors may impact the efficacy of standard NPO times.

First-line Gemcitabine Treatment of Physician's Choice for Metastatic Breast Cancer: A Prospective Cohort Study.

Background/aim: This study aimed to investigate the efficacy of first-line gemcitabine monotherapy for metastatic breast cancer (MBC) and its effect on health-related quality of life (HRQoL) compared with treatment of physician's choice (TPC).

Patients And Methods: We enrolled 96 patients into the first-line gemcitabine group (n=47) or other treatment of physician's choice (TPC) group (n=49) from May 2010 to April 2013. HRQoL was evaluated every 4 weeks.

Influenza vaccine effectiveness against influenza A in children based on the results of various rapid influenza tests in the 2018/19 season.

During influenza epidemics, Japanese clinicians routinely conduct rapid influenza diagnostic tests (RIDTs) in patients with influenza-like illness, and patients with positive test results are treated with anti-influenza drugs within 48 h after the onset of illness. We assessed the vaccine effectiveness (VE) of inactivated influenza vaccine (IIV) in children (6 months-15 years old, N = 4243), using a test-negative case-control design based on the results of RIDTs in the 2018/19 season. The VE against influenza A(H1N1)pdm and A(H3N2) was analyzed separately using an RIDT kit specifically for detecting A(H1N1)pdm09.

Micro-arteriovenous fistula in patients with lower limb lymphedema.

Background: A micro-arteriovenous fistula (AVF) is a minute, short shunt between an artery and a vein that does not pass through a capillary. We investigated the association between micro-AVFs and lymphedema using computed tomography angiography (CTA) and venous blood gas analysis.

Methods: In 95 patients with lower limb lymphedema, the presence or absence of early venous return (EVR) was compared between patients with primary and secondary lymphedema.
