We herein report a case of gastric hyperplastic polyps after argon plasma coagulation (APC) for gastric antral vascular ectasia (GAVE) in the antrum of a 65-year-old man with liver cirrhosis and hypergastrinemia induced by long-term proton pump inhibitor (PPI) use. Two years after APC therapy, endoscopy demonstrated multiple gastric polyps in the antrum and angle. A gastric polyp biopsy indicated foveolar epithelium hyperplasia, which was diagnosed as gastric hyperplastic polyps. AS1517499 price One year after switching to an H2 blocker antagonist, endoscopy revealed that the polyps and GAVE had disappeared, with normal gastrin levels suggesting that PPI-induced hypergastrinemia had caused gastric hyperplastic polyps after APC therapy, and the polyps had disappeared after discontinuing PPIs.Bone marrow necrosis (BMN) is a rare but important complication of hematological malignancies. We report the case of a 52-year-old male patient with a recurrence of acute lymphoblastic leukemia (ALL) accompanied by BMN. After re-induction therapy, bone marrow aspiration (BMA) and biopsy from the iliac bone showed necrotic cells and eosinophilic debris, respectively. Magnetic resonance imaging (MRI) showed heterogeneous signals in the bilateral iliac bone, possibly reflecting various stages of BMN. BMA from the sternum eventually revealed the recurrence of ALL after a few weeks. Comprehensive assessments, including MRI and repeated bone marrow tests, are required when evaluating the underlying hematological malignancies of patients with BMN.A 45-year-old woman was referred to our hospital for the evaluation of proximal muscle weakness and serum creatinine kinase elevation. She had atrial fibrillation and left ventricular asynergy. She was diagnosed with myopathy, accompanied by cardiomyopathy of unknown etiology. She was treated with prednisolone. After long-term follow-up and a detailed examination, the patient was diagnosed with antimitochondrial antibody (AMA)-associated myopathy with cardiac involvement. Although the patient received medical treatment, including beta-blockers and prednisolone, her cardiac function deteriorated progressively. Physicians should consider AMA-associated myopathy when diagnosing myopathies of unknown etiology. The presence of cardiac involvement should be proactively investigated in AMA-associated myopathy.We herein report the definitive diagnosis of rectovaginal endometriosis in two cases. Case 1 involved a 46-year-old woman with abdominal pain and hematochezia. The diagnosis after the first and second examinations using lower gastrointestinal (GI) endoscopy was unclear. Differential diagnoses included mucosa-associated lymphoid tissue and colorectal cancer. The third lower GI endoscopy with a targeted biopsy, performed during menstruation, confirmed rectovaginal endometriosis. Case 2 involved a 38-year-old woman with hematochezia. Lower GI endoscopy during menstruation revealed rectovaginal endometriosis. When rectovaginal or bowel endometriosis is suspected, lower GI endoscopy and a targeted biopsy during menstruation can prevent unnecessary surgery.Aortic stenosis (AS), a late complication of thoracic radiation therapy for chest lesions, is often coincident with porcelain aorta or hostile thorax. We herein report a 59-year-old man with a history of mediastinal Hodgkin lymphoma treated with radiation therapy but later presenting with heart failure caused by severe AS. Severe calcification in the mediastinum and around the ascending aorta made it difficult to perform surgical aortic valve replacement. The patient therefore underwent transcatheter aortic valve implantation (TAVI). It is important to recognize radiation-induced AS early, now that TAVI is a well-established treatment required by increasing numbers of successfully treated cancer patients.A 43-year-old man with a preceding infection was transferred to our hospital for febrile status epilepticus (SE). Although treatment for SE was immediately initiated, it failed. Therefore, continuous anesthetics treatment with mechanical ventilation was initiated. No epileptic discharge was found on an electroencephalogram. However, total aphasia and right hemiplegia due to left hemispheric swelling were noted on day 5. His aphasia and hemiplegia did not improve. The mechanism underlying the hemispheric involvement remains unclear. The initial diagnosis should be made with care in patients with febrile SE; furthermore, intensive treatment should be administered in the acute phase.

To investigate inter- and intra-individual variation in the levels and outputs (concentration multiplied by salivary flow rate) of salivary metabolites in patients with primary Sjögren's syndrome (pSS).

A total of 56 samples of stimulated saliva were collected from 14 female pSS patients during four laboratory visits within 20 weeks and analyzed using proton nuclear magnetic resonance spectroscopy. Single saliva samples from each of 15 controls were also analyzed.

Among 21 quantified metabolites, choline was significantly elevated in the pSS patients at each time point (P ≤ 0.015), taurine at the last three time points (P ≤ 0.013), alanine at the last two time points (P ≤ 0.007) and glycine at the last time point (P = 0.005). Inter-individual variation in metabolite concentrations was generally larger among the patients than among the controls, and significantly large variations were observed for glycine (P ≤ 0.007, all time points), choline (P ≤ 0.033, three last time points) and alanine (P = 0.028, baseline). Metabolite output analysis showed that choline had the lowest intra-patient variation.

In spite of considerable intra- and inter-individual variation, levels and outputs of specific metabolites in patients with pSS differ from those in controls, and may be potentially applicable as new biological markers for monitoring of the response to treatment.

Forty-nine serum samples were obtained from 23 preterm neonates (age, 34.1 ± 18.8 d), and additive blood sampling was conducted periodically for 10 of the 23 patients after discontinuation of CAF treatment. The concentrations of CAF and its major metabolites were determined by liquid chromatography-tandem mass spectrometory. The serum concentrations of CAF were within therapeutic levels (5-25 µg/mL) in 37 samples and exceeded 25 µg/mL in the rest of the 12 samples, although no sample was in the toxic range (> 50 µg/mL). The inter- and intra-individual variability of the concentration to dose (C/D) ratio corrected for body surface area (BSA) was more negatively associated with postmenstrual age (PMA) rather than postnatal age (PNA). The serum concentrations of major metabolites were much smaller than those of CAF throughout the study, suggesting that the contribution of hepatic metabolism to drug elimination was small in the preterm infants under 241 d of PMA. The mean values for elimination half-life and oral clearance estimated in the 10 patients were 124.6 ± 44.6 h and 2.26 ± 0.73 mL/min/1.73 m2, respectively. Consequently, we confirmed that the exposure to CAF was considerably variable and provided additive insight that the C/D ratio corrected for patient's BSA and PMA are promising for describing and understanding the developmental change of clearance in preterm infants.Duck viral enteritis (DVE) is a lethal viral disease caused by duck enteritis virus (DEV) via an unknown mechanism. This study explores the relationship between Chinese standard challenge strain DEV (DEV-CSC)-induced apoptosis and endoplasmic reticulum stress (ERS) in duck embryo fibroblast (DEF) cells. Here we examined changes in Ca2+ concentration, cell proliferation, apoptosis, and the differential expression of C/EBP homologous protein (CHOP), glucose regulatory protein 78 (GRP78), and activating transcription factor 6 (ATF6) in infected cells. The results revealed that DEV-CSC infection significantly decreased Ca2+ concentration, suppressed cell viability, and induced apoptosis in DEF cells. Further experiments also demonstrated that DEV-CSC infection significantly upregulates CHOP, GRP78, and ATF6 expression. In addition, we show that the addition of ethylenediaminetetraacetic acid (EDTA) reverses the induction of apoptosis and the ERS mediated inhibition of cell viability in DEF cells associated with DEV-CSC infection. Therefore, we can conclude that infection with DEV-CSC induces apoptosis and ERS reducing the viability of DEF cells via the regulation of Ca2+. These findings may provide a new target for the treatment of DVE.

The clinical significance of osteoporosis in chronic heart failure (CHF) remains unclear.Methods and ResultsA total of 303 CHF patients (75 years, [interquartile range (IQR) 66-82 years]; 41% female) were retrospectively examined. Bone mineral densities (BMDs) at the lumbar spine, femoral neck, and total femur were measured by using dual-energy X-ray absorptiometry (DEXA), and osteoporosis was diagnosed when the BMD at any of the 3 sites was <70% of the Young Adult Mean percentage (%YAM). The prevalence of osteoporosis in CHF patients was 40%. Patients with osteoporosis were older (79 [IQR, 74-86] vs. 72 [IQR, 62-80] years), included a large percentage of females, had slower gait speed and had a lower body mass index. Multivariate logistic regression analysis indicated that sex, BMI, gait speed, loop diuretics use and no use of direct oral anticoagulants (DOACs) were independently associated with osteoporosis. Kaplan-Meier survival curves showed that the rate of death and heart failure hospitalization was higher in patients with osteoporotic BMD at 2 or 3 sites than in patients without osteoporosis (hazard ratio 3.45, P<0.01). In multivariate Cox regression analyses, osteoporotic BMD at 2 or 3 sites was an independent predictor of adverse events after adjustment for prognostic markers.

Loop diuretics use and no DOACs use are independently associated with osteoporosis in CHF patients. Osteoporosis is a novel predictor of worse outcome in patients with CHF.

Sedentary behavior may be an independent risk factor for cardiovascular events. This study aimed to clarify the effects of extended sedentary time in patients with diabetic kidney disease (DKD) on the risk of all-cause death and new events.Methods and ResultsA prospective cohort study was performed over 39 months. The study included 173 patients with DKD who completed the International Physical Activity Questionnaire (IPAQ) (101 men; mean age, 71±11 years); 37 patients (21.4%) were diagnosed with cardiovascular disease (CVD). New events were defined as all-cause death, cerebral stroke, or CVD requiring hospitalization or commencing hemodialysis (HD). Data were analyzed using a multivariate Cox proportional hazard regression model with variables, including sedentary time. There were 34 cases of new events during the observation period, including 4 cases of stroke, 20 cases of CVD, 4 cases of HD implementation, and 6 cases of death. Hazard ratio (HR) calculations for the new event onset group identified sedentary time as a significant independent variable.
