    Objective In an effort to reduce mortality from gastric cancer, endoscopic screening was introduced in 2016 as a nationwide screening program in Japan. Recent developments in high-definition endoscopic imaging and diagnostic strategies have enabled the simultaneous detection of other upper gastrointestinal (U-GI) malignancies. Therefore, we conducted a study to evaluate the feasibility of endoscopic screening for U-GI malignancy in a comprehensive health checkup.

    Methods We retrospectively reviewed the data of 13,120 participants who had received a comprehensive health checkup in a single institution between April 2012 and March 2018. Participants were divided into two groups [gastrointestinal endoscopy (GIE) group (n=9,142) and gastrointestinal X-ray (X-ray) group (n=3,978)] and compared with regards to the screening results, adverse events, and detection rate of U-GI malignancies (gastric cancer or other) using a propensity-score matched analysis.

    Results The gastric cancer detection rate was significantly higher in the GIE group [34/9,142 (0.48%)] than in the X-ray group [3/3,978 (0.08%)] (p=0.003). Other U-GI malignancies were found only in the GIE group and comprised two hypopharyngeal cancers, five esophageal cancers, two duodenal cancers, and one duodenal gastrointestinal stromal tumor. Adverse events occurred in 6/9,142 (0.07%) participants in the GIE group and 18/3,978 (0.45%) participants in the X-ray group (p<0.0001). A propensity-score matched analysis yielded 1,551 matched pairs, and the detection rate of gastric cancer and other U-GI malignancies remained significantly higher in the GIE group than in the X-ray group.

    Conclusion This study indicated that not only gastric cancer but also other U-GI malignancies can be detected by endoscopic screening.

    Objective This study evaluated the efficacy associated with switching to rifaximin in patients with hepatic cirrhosis receiving kanamycin sulfate for the treatment of hepatic encephalopathy and hyperammonemia.

    Methods We included 37 patients who switched from kanamycin sulfate to rifaximin at our institution from January 2017 to December 2018. The onset of hepatic encephalopathy and changes in blood ammonia values during a six-month period were retrospectively evaluated.

    Results There were 4 (11%) patients with hepatic encephalopathy at the time of switching from kanamycin sulfate to rifaximin. The cumulative incidence of hepatic encephalopathy was 3% and 16% at 3 and 6 months later, respectively. The blood ammonia levels at the time of switching to rifaximin and at 3 and 6 months later were 94 (range, 20-243) μg/dL, 95 (range, 33-176) μg/dL, and 81 (range, 32-209) μg/dL, respectively, and no significant changes were observed. However, in the 11 patients receiving an oral dose of <1,500 mg/day of kanamycin sulfate, the blood ammonia levels at the time of switching and at 3 and 6 months later were 136 (range, 35-243) μg/dL, 95 (range, 33-150) μg/dL, and 63 (range, 43-124) μg/dL, respectively. Furthermore, the blood ammonia levels significantly decreased at the time of the switching to rifaximin and at three and six months later (p=0.043 and p=0.011, respectively).

    Conclusion Switching to rifaximin in hepatic cirrhosis patients receiving kanamycin sulfate to treat hepatic encephalopathy and hyperammonemia showed effects that were equivalent to or greater than the original therapy, thereby demonstrating the clinical efficacy.

    Objective Current clinical guidelines have proposed heart failure (HF) with mid-range ejection fraction (HFmrEF), defined as a left ventricular ejection fraction (LVEF) of 40-49%, but the proportion and prognosis of patients transitioning toward HF with a reduced LVEF (LVEF <40%, HFrEF) or HF with a preserved LVEF (LVEF ≥50%, HFpEF) are not fully clear. The present study prospectively evaluated the changes in the LVEF one year after discharge and the outcomes of hospitalized patients with HFmrEF.

    Methods We prospectively studied 259 hospitalized patients with HFmrEF who were discharged alive at our institutions between 2015 and 2019. Among them, 202 patients with HFmrEF who underwent echocardiography at the one-year follow-up were included in this study. Patient characteristics, echocardiographic data and all-cause death were collected.

    Results Eighty-seven (43%) patients transitioned to HFpEF (improved group), and 35 (17%) transitioned to HFrEF (worsened group). During a median follow-up of 33 months, 27 (13%) patients died. After adjustment, patients in the worsened group had an increased risk of all-cause mortality compared with those in the improved group [hazard ratio 7.02, 95% confidence interval (CI) 1.13-43.48]. The baseline LVEF (per 1% decrease) and tricuspid annular plane systolic excursion (per 1 mm decrease) were independent predictors of the worsened LVEF category (odds ratio 2.13, 95% CI 1.25-3.63 and odds ratio 1.31, 95% CI 1.01-1.70, respectively).

    Conclusion Our study showed that a worsened LVEF one year after discharge was associated with a poor prognosis in hospitalized patients with HFmrEF.

    Objective The coronavirus disease 2019 (COVID-19) pandemic has resulted in a shortage of medical resources, including ventilators, personal protective equipment, medical staff, and hospital beds. We investigated the impact of COVID-19 in amyotrophic lateral sclerosis (ALS) patients, their families, caregivers, and medical experts.

    Methods We conducted a nationwide ALS webinar about COVID-19 in May 2020 and sent a questionnaire to those enrolled.

    Results A total of 135 participants (31 ALS patients; 23 families and caregivers of ALS patients; 81 medical experts) responded to this cross-sectional self-report questionnaire. The results showed that tracheostomy and invasive ventilation (TIV) was used in 22.6% of ALS patients, whereas 77.4% of ALS patients were not under TIV. Among non-TIV patients (n=24), 79.2% did not want TIV in the future. However, 47.4% of non-TIV patients not wanting a tracheostomy in advanced stages replied that they would want an emergency tracheostomy if they developed COVID-19-related pneumonia. These results suggest that ALS patients may be receptive to emergency treatments for reasons other than ALS. In addition, approximately half of the ALS patients agreed with the policy of not ventilating the elderly or ALS patients in case of a ventilator shortage. Furthermore, compared with medical experts, few ALS patients reported that the chance for ALS patients to obtain work was higher due to the increasing availability of remote work.

    Conclusions This survey indicates that the COVID-19 pandemic might be associated with increased distress about access to care and work, inducing contradictory responses and potential hopelessness among ALS patients.
