The purpose of this study was to investigate the clinical problems recognized and reported by healthcare workers (HCWs) who handle medical devices and analyze the factors associated with each problem, in order to investigate the development of blood collection support devices that are not widely used. An online survey was administered to 300 HCWs registered with a net research company to investigate how the intensity and frequency of 10 predetermined clinical problems would be reported. The relationship between the clinical problems and the attributes of the survey subjects was then analyzed using logistic regression analyses. As a result, the clinical problems frequently reported by the respondents were, to reduce labor, simplify data management, and obtain good medical materials. The need for imaging devices was reported to be low. The larger the scale of the medical institution, the more the problems reported by the HCWs. The fewer years of experience the HCWs had, the more likely they were to report a greater number of issues. In the development of blood collection support devices, it is necessary to listen to the opinions of HCWs with short clinical experience, working in large medical institutions and prioritize the development of devices that reduce labor.

Introduction: Interstitial lung disease (ILD) patients often develop lung cancer (LC). However, previous studies on the incidences of LC in ILDs focused on specific aetiologies, such as idiopathic pulmonary fibrosis (IPF). To investigate the incidences of LC in ILDs other than IPF, we conducted this study. Materials and Methods: ILD patients at our hospital were retrospectively reviewed. The cumulative incidences of LC in various ILD patients were estimated and compared among ILD groups for up to five years. The association between several variables at initial diagnosis and LC development was assessed to identify predictors. Results: In all, 587 ILD patients, including 161 IPF, 160 chronic HP, 133 non-IPF idiopathic interstitial pneumonias (IIPs), 87 connective tissue disease-related ILDs (CTD-ILDs), and 46 other ILDs, were included. Twenty-seven patients developed LC. The cumulative incidences of LC at 1, 3, and 5 years were 1.9%, 5.7%, and 12.3% in IPF, respectively; 2.0%, 4.6%, and 11.0% in chronic HP; 0.8%, 0.8%, and 4.0% in non-IPF IIPs; and 1.1%, 1.1%, and 2.9% in CTD-ILDs. Chronic HP patients had a high incidence of LC as IPF patients. Pack-years was associated with LC development in chronic HP patients. Conclusions: The incidences of LC are equally high in patients with chronic HP and IPF.

Purpose: A rapid deterioration of oral health after high school age is an issue to be addressed in Japan. Although this problem may relate to the weakness of oral health promotion for university students, the investigation of oral health-promoting activities, including annual dental checkups (DCs), undertaken by universities has never been conducted. Therefore, a questionnaire survey among health administration departments (HADs) was conducted to clarify the status of oral health-promoting activities for students. Methods: Self-administered questionnaire was voluntarily answered by HAD’s staff in 2015-2016. The major questions were on information concerning the university, HAD’s staff, implementation of DCs, and oral health-promoting activities for students. Results: Of 295 universities, 130 valid responses (response rate 44.1%) were analyzed. DCs were implemented in 10.9% of the universities. The main reasons for not implementing DCs were the large budgetary burden and low needs of students. The dental clinic introductory service was undertaken by 62.3%, whereas provision of oral health information was undertaken by only 23.8%. Conclusion: A low ratio of universities implemented DCs and provided oral health information. Further expansion of DC implementation is considered difficult because of the budgetary burden. Promoting the provision of oral health information from universities is required to improve students’ oral health.
