    Objective Diffuse mucosal inflammation in the duodenum, distinct from peptic ulcer disease, has been repeatedly reported in patients with ulcerative colitis (UC). The pathogenesis of this complication remains uncertain; however, colectomy for medically refractory UC appears to trigger duodenitis. Cases in which colectomy was performed for UC were analyzed to characterize UC-related duodenitis after colectomy.

    Methods A retrospective case-control study of UC-related duodenitis that developed after colectomy in medically refractory UC between January 2011 and June 2020 was conducted. UC-related duodenitis was diagnosed based on typical clinical, endoscopic, and histological findings, and no duodenitis was endoscopically defined by the normal duodenal mucosa. Clinical and laboratory data, disease severity, and medications used were collected and compared between the UC-related and non-duodenitis cases.

    Results Ten UC-related duodenitis and 35 non-duodenitis cases were identified among 45 patients with UC who underwent esophagogastroduodenoscopy after colectomy. Disease severity, defined by the C-reactive protein level and partial Mayo score prior to colectomy, was significantly higher in duodenitis patients than in non-duodenitis patients. In comparison to non-duodenitis patients, duodenitis patients more frequently received rescue therapies with calcineurin inhibitors or anti-tumor necrosis factor (TNF)-α agents at the time of colectomy (100% vs. 65.7%).

    Conclusion Patients with UC with higher disease activity, especially those who require rescue therapies with calcineurin inhibitors and anti-TNF-α agents, may be prone to developing UC-related duodenitis after colectomy.

    Objective The daily step count is associated with mortality in idiopathic pulmonary fibrosis (IPF). However, the factors associated with this phenomenon are not yet fully understood. We therefore clarified its association with clinical parameters.

    Methods Fifty-nine patients with IPF with available data for daily step counts; 6-minute walk distance (6MWD); chest, abdominal, and pelvic computed tomography (CT); pulmonary function; psychological evaluations; and sarcopenia assessments were prospectively enrolled. The daily step count was measured continuously for seven consecutive days. The cross-sectional areas of the erector spinae muscles at the level of the 12th vertebra (ESMCSA) and psoas major muscle volume (PMV) obtained by CT were assessed.

    Results The average age of the patients was 73.3±8.1 years old, and the percent predicted forced vital capacity was 81.6%±15.8%. The median daily step count was 4,258 (2,155-6,991) steps. The average 6MWD, ESMCSA, and PMV were 413±97 m, 25.5±6.7 cm2, and 270±75.6 cm3, respectively. A linear regression analysis for daily step count showed that the ESMCSA and 6MWD were independent factors for the daily step count, whereas the PMV and skeletal muscle index were not. The daily step count, ESMCSA, and 6MWD were lower in patients with sarcopenia than in those without sarcopenia.

    Conclusion A lower daily step count was associated with a smaller erector spinae muscle area and sarcopenia in patients with IPF. Further studies are warranted to confirm the importance of physical therapy for muscle strengthening in patients with IPF.

    Objective The changes in the prevalence of acute meningitis during the coronavirus disease 2019 (COVID-19) pandemic remain unclear. This study aimed to compare the prevalence of acute meningitis before and during the COVID-19 pandemic in Japan.

    Methods We retrospectively reviewed the Japanese nationwide administrative medical payment system database, Diagnosis Procedure Combination (DPC), from 2016 to 2022. A total of 547 hospitals consistently and seamlessly offered DPC data during this period. The study period was divided into the following three periods: April 2016 to March 2018 (fiscal years 2016-2017), April 2018-March 2020 (2018-2019), and April 2020-March 2022 (2020-2021).

    Results Among the 28,161,806 patients hospitalized during the study period, 28,399 were hospitalized for acute meningitis: 16,678 for viral/aseptic type, 6,189 for bacterial type, 655 for fungal type, 429 for tuberculous, 2,310 for carcinomatous type, and 2,138 for other or unknown types of meningitis. A significant decrease during the pandemic was confirmed in viral (n=7,032, n=5,775, and n=3,871 in each period; p<0.0001) and bacterial meningitis (n=2,291, n=2,239, and n=1,659; p<0.0001) cases. Meanwhile, no decrease was observed in fungal meningitis (n=212, n=246, and n=197; p=0.056) or carcinomatous meningitis (n=781, n=795, and n=734; p=0.27). The decrease in the number of tuberculous meningitis cases was equivocal (n=166, n=146, and n=117; p=0.014). The decrease during the pandemic was more remarkable in younger populations aged <50 years than in older populations, both for viral and bacterial meningitis.

    Conclusion The number of hospitalized cases of acute meningitis clearly decreased during the COVID-19 pandemic, especially for viral and bacterial meningitis in younger populations aged <50 years.

    Objective This study evaluated the implementation status of morbidity and mortality conferences in internal medicine specialty training programs in Japan.

    Methods This cross-sectional study surveyed hospitals in Japan with certified internal medicine specialty training programs. Program directors or equivalently responsible physicians managing certified internal medicine training programs were invited to participate in this study (n=619).

    Materials Data were collected using an online questionnaire that included questions about the number of morbidity and mortality conferences, types of cases covered, collaboration of the patient safety section and other health professions, and whether or not the conferences were conducted by a subspecialty department-led or program-based.

    Results Responses were received from 123 hospitals (19.8% response rate), of which 59 (48%) had some form of internal medicine morbidity and mortality conference in place. The average number per year was 9.63 (standard deviation: 18.12). Hospitals with morbidity and mortality conferences in subspecialty departments held significantly more conferences. Furthermore, the involvement of the patient safety department tended to be associated with holding more conferences. Autopsy rates were significantly higher in hospitals with program-based internal medicine morbidity and mortality conferences than subspecialty-led.

    Conclusion Internal medicine specialty training hospitals had more morbidity and mortality conferences than previously reported. Program-based morbidity and mortality conferences in internal medicine are associated with higher autopsy rates and may lead to an organizational reporting culture and lifelong learning attitudes that support patient safety. Collaboration with organizational management sections, such as patient safety, would be effective in implementing these conferences in internal medicine training programs.
