AIM: Akita Prefecture has the largest proportion of older inhabitants and the highest cancer mortality rate in Japan. Lung cancer is one of the biggest killers, and early detection is critical. Chest X-ray examinations are the main screening method for lung cancer; however, the COVID-19 pandemic has affected the screening system. Here, we evaluate how COVID-19 has affected lung cancer screening in Akita Prefecture. METHODS: Using the Akita General Health Corporation database, the average annual number of chest X-ray screening tests, close examinations and lung cancer diagnoses (stratified by sex and age) was evaluated during 2016-2019, and compared with the 2020 values. Furthermore, data on lung cancer registrations from 2018 to 2020 were obtained from the Collaborative Akita Prefecture Hospital-Based Cancer Registration System and analyzed. RESULTS: The average annual number of screening tests, close examinations and lung cancer diagnoses declined (by >50%) between 2016 to 2019 and 2020, especially among older people (aged ≥65 years). Furthermore, by stage, the number of patients with early-stage lung cancer (stage 0-I) decreased, and the number with advanced-stage cancer (stage IV) increased. CONCLUSIONS: The COVID-19 pandemic reduced lung cancer screening participation, especially among the older adult population in Akita Prefecture, resulting in a decrease in lung cancer diagnoses through screening. This might have reduced the number of early-stage cancer registrations. It is necessary to improve health education among the public regarding the importance of chest X-ray screening.

BACKGROUND/AIM: To investigate the association between the number of circulating endothelial progenitor cells (EPCs) in non-squamous non-small cell lung cancer (NSCLC) and disease outcome, in combination chemotherapy with and without bevacizumab. MATERIALS AND METHODS: We retrospectively identified 25 non-squamous NSCLC cases, and divided them into high-EPC and low-EPC groups. Within each group, we compared disease outcomes, with or without the administration of bevacizumab. RESULTS: In the high-EPC group, chemotherapy with bevacizumab produced a significantly higher tumor reduction rate and objective response rate, with significantly longer progression-free survival, compared to chemotherapy without bevacizumab (p<0.001, p=0.010, and p<0.001, respectively). However, in the low-EPC group, there were no significant differences in disease outcomes in groups with versus those without bevacizumab. CONCLUSION: The number of EPCs may be a useful biomarker to guide decision-making in the use of bevacizumab in non-squamous NSCLC.

<p><b>Aim: </b>To consider what is necessary to ensure the efficient performance of dementia community support coordinators.</p><p><b>Methods: </b>In Akita Prefecture, we conducted a simple questionnaire survey of dementia community support coordinators in 25 municipalities to clarify the current status of their activities and examine what needs to be done to develop their projects more efficiently.</p><p><b>Results: </b>It became clear that residents were not aware of the existence of these coordinators, underscoring the need to publicize their existence and activities. The lack of tools to improve the public's understanding of social resources for sharing information on building a support system was also demonstrated. In terms of cooperation, it was found that, despite the establishment of cooperation with IPIST and the medical center for dementia, cooperation with dementia support coordinators was insufficient. Furthermore, we confirmed that support coordinators were not very involved in the creation and activities of dementia care paths.</p><p><b>Conclusions: </b>Based on the above findings, we propose five points to support further efficient development. 1. Disseminate information to inform local residents about dementia community support coordinators, 2. Collaborate with dementia support coordinators and the welfare commissioner, 3. Create social resource maps and facilitate their understanding and establish dementia care path activities, 4. Create a work environment where dementia community support coordinators do not have to work concurrently, and 5. Create learning opportunities to improve understanding of the overall dementia policy.</p>

<p>The purpose of this study was to clarify the trends in the activity of the initial-phase intensive support teams in Akita Prefecture and to, clarify the factors contributing to the more efficient promotion of future projects. A survey was conducted by questionnaire among 46 initial-phase intensive support team member for dementia. The results indicated that it is mostly maintained cooperation medical center for dementia and community support promoter for dementia. However, the question was insufficient cooperation with family doctor including visit the home. These findings suggest that it is important to disseminate information and improve awareness among the community as well as foster relationships of trust by families.</p>
