Crosstalk Between Omental Adipose-Derived Stem Cells and Gastric Cancer Cells Regulates Cancer Stemness and Chemotherapy Resistance.

Peritoneal metastasis (PM) remains a major challenge in patients with gastric cancer (GC) and occurs preferentially in adipose-rich organs, such as the omentum. Adipose-derived stem cells (ASCs) may influence cancer behavior. This study aimed to investigate whether ASCs isolated from the omentum can act as progenitors of cancer-associated fibroblasts (CAFs) and analyze their effects on the cancer stem cell (CSC) niche and the treatment resistance of GC cells.

Utility of beta-human chorionic gonadotropin in pleural effusions: Report of an autopsy case of a male patient with primary pulmonary choriocarcinoma.

A 69-year-old male patient presented with bloody pleural fluid effusion and elevated beta-human chorionic gonadotropin (β-hCG) levels obtained by thoracentesis. The patient's condition rapidly deteriorated, and he died. The autopsy revealed primary pulmonary choriocarcinoma.

Early Detection of Symptom Exacerbation in Patients With SARS-CoV-2 Infection Using the Fitbit Charge 3 (DEXTERITY): Pilot Evaluation.

Background: Some patients with COVID-19 experienced sudden death due to rapid symptom deterioration. Thus, it is important to predict COVID-19 symptom exacerbation at an early stage prior to increasing severity in patients. Patients with COVID-19 could experience a unique "silent hypoxia" at an early stage of the infection when they are apparently asymptomatic, but with rather low SpO (oxygen saturation) levels.

Diagnostic sensitivity of cutoff values of IgG4-positive plasma cell number and IgG4-positive/CD138-positive cell ratio in typical multiple lesions of patients with IgG4-related disease.

Objectives: This study aimed to investigate the diagnostic sensitivity of the cutoff values of IgG4-positive plasma cell (PC) number and IgG4-positive/CD138-positive cell ratio proposed by the International consensus statement (ICS) on the pathology of IgG4-related disease (IgG4-RD) in typical multiple lesions of patients with IgG4-RD.

Methods: We evaluated IgG4-positive PC number and IgG4-positive/CD138-positive cell ratio in 39 samples from 18 IgG4-RD patients having more than two typical lesions of IgG4-RD.

Results: We evaluated 12 submandibular, 12 ophthalmic, six skin, five kidney, two pancreatic, and one bronchus and prostate lesion each in 18 patients with typical clinical, serological, and radiographic features.

Interobserver agreement in detection of "white globe appearance" and the ability of educational lectures to improve the diagnosis of gastric lesions.

Background: White globe appearance (WGA) refers to a small white lesion of globular shape underneath cancerous gastric epithelium that can be clearly visualized by magnifying endoscopy with narrowband imaging (M-NBI). WGA has been reported to be a novel endoscopic marker that is highly specific in differentiating early gastric cancer (GC) from low-grade adenoma, and has a significantly higher prevalence in early GCs than in noncancerous lesions. However, interobserver agreement in detecting WGA and whether training intervention can improve diagnostic accuracy are unknown.

Patients with End-stage Interstitial Lung Disease may have More Problems with Dyspnea than End-stage Lung Cancer Patients.

Introduction: Patients with end-stage interstitial  lung disease (ILD) do not appear to receive adequate palliative care despite apparent suffering before death. The aim of this study was to evaluate their signs, symptoms, and treatment received before death.

Methods: Patients with ILD and lung cancer (LC) who were hospitalized and died in our hospital were enrolled retrospectively.

Antisynthetase syndrome: Pulmonary computed tomography findings of adult patients with antibodies to aminoacyl-tRNA synthetases.

Objectives: To describe the pulmonary CT findings in patients with anti-ARS-antibody-positive interstitial lung disease (anti-ARS-ILD) METHODS: The CT findings of 64 patients with anti-ARS-ILD were retrospectively reviewed. The images were retrospectively reviewed independently by 2 chest radiologists, and the final decision on the CT findings was made by a third chest radiologist.

Results: There were 16 male and 48 female patients, aged 54.
