Treatment preferences among Japanese patients and physicians for epidermal growth factor receptor-mutant non-small cell lung cancer.

INTRODUCTION: Evidence is limited on preferences of Japanese patients and physicians in treatment for epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC). Several oral or intravenous novel agents for EGFR exon 20 insertions are under development. The aim of our study was to investigate which attributes of novel treatments influenced selection of oral or intravenous agents among treated patients and treating physicians in Japan. METHODS: The study was designed by board-certified oncologists, patient representatives, and analytics specialists. Eligible participants completed an online survey with a discrete choice experiment presenting two treatment profiles described by attributes: mode of administration (oral or intravenous); frequency of administration; overall response rate (ORR); average progression-free survival (PFS); chance of experiencing severe side effects (SEs); mild-moderate gastrointestinal SEs; mild-moderate skin-related SEs; and patient out-of-pocket costs. RESULTS: Fifty-four patients (all self-reported EGFR-mutant) and 74 physicians participated from December 2021 to August 2022. All attributes being equal, there was greater preference for oral administration. However, there was greater preference for intravenous over oral, when ORR and PFS improved by 10% and 1 month, and severe SEs reduced by 10%. Physicians exhibited greater preference for PFS compared to patients (p < 0.01). Ranked order of attribute importance was as follows: (1) PFS; (2) ORR; (3) severe SEs, expressed by patients and physicians alike. CONCLUSIONS: Our study revealed Japanese physician and patient preferences in treatment options for EGFR-mutant NSCLC. Compared to the strong preference for a more efficacious drug, the preference of oral versus intravenous revealed a smaller impact.

Work-related psychosocial factors and inflammatory markers: A systematic review and meta-analysis.

OBJECTIVE: We conducted a systematic review and meta-analysis to evaluate the prospective effect of adverse work-related psychosocial factors on increases in inflammatory markers. METHODS: A systematic literature search was conducted in PubMed, Embase, PsycINFO, PsycARTICLES, and the Japan Medical Abstracts Society database. Studies were eligible for inclusion if they examined associations between work-related psychosocial factors and inflammatory markers (interleukin-6, tumor necrosis factor-alpha, and C-reactive protein), used longitudinal or prospective cohort designs, were conducted among workers, were original articles written in English or Japanese, and were published up to 2017 for the first search, October 2020 for the second, and November 2022 for the third. A meta-analysis was conducted using a random-effects model to assess the pooled effect size for the associations. A meta-regression analysis was used to estimate the association between length of follow-up and effect size. The ROBINS-I tool was used to assess risk of bias. RESULTS: Of the 11,121 studies identified in the first search, 29,135 studies from the second, and 9448 studies from the third, eleven were eligible for this review and meta-analysis. The pooled coefficient between adverse work-related psychosocial factors and inflammatory markers was significant and positive (ß = 0.014, 95% confidence interval: 0.005-0.023). However, a clear association was only observed for interleukin-6, and all the studies included had serious risks of bias. Meta-regression showed the effect size decreased depending on the follow-up period. CONCLUSION: This study revealed a weak positive association between adverse work-related psychosocial factors and increases in inflammatory markers.

[Current status and intention to change indoor smoking rules by enforcing smoke-free legislation in Japan].

Objective　In Japan, the revised Health Promotion Act and the Tokyo Metropolitan Ordinance to Prevent Exposure to Second-hand Smoke have been in place since April 1, 2020. However, regional differences in the prohibition of smoking in restaurants have raised concerns that some restaurants are not regulated by the smoke-free legislation. In addition, outdoor smoking rules have been in place in municipalities prior to the smoke-free legislation, so smoking outside restaurants may occur, and this may obstruct progress in the prohibition of smoking. In this study, we examined the indoor smoking rules before and after the enforcement of the smoke-free legislation, as well as what influenced the changes in these rules.Methods　We conducted a self-administered questionnaire survey in 6,000 restaurants in Tokyo, Osaka, and Aomori prefectures from February to March 2020. We examined the indoor smoking rules before and after the enforcement of the smoke-free legislation and calculated the proportion of change by categorizing the indoor smoking rules into "smoking prohibited," "smoking permitted in separate area," and "smoking permitted."Results　Of the 879 restaurants that responded, 603 indicated that they were not regulated by the smoke-free legislations. The percentage of restaurants that switched from "smoking permitted in separate area" and "smoking permitted" to "smoking prohibited" was 5.2% (3/58) in Tokyo, 23.1% (31/134) in Osaka, and 17.2% (57/326) in Aomori. In addition, when we included restaurants that were already "smoking prohibited" before the enforcement and did not plan to change the rules after the enforcement, the percentage was 46.6% (55/118) in Tokyo, 49.6% (113/228) in Osaka, and 48.6% (125/257) in Aomori.Conclusion　In total, 17.6% (91/518) of the restaurants that were not regulated by the smoke-free legislations would plan to change their indoor smoking rules from "smoking permitted in separate area" and "smoking permitted" to "smoking prohibited." There is a concern regarding the reduction in customers and sales due to the prohibition of smoking, and the existence of outdoor smoking rules prior to the smoke-free legislation may obstruct progress in the prohibition of smoking. It will be important to examine changes in the number of customers and sales resulting from changes to the indoor smoking rules to deal with smokers when smoking is prohibited, and to improve environments set as public smoking spaces in Japan.

Associations of non-standard employment with cardiovascular risk factors: findings from nationwide cross-sectional studies in Japan.

This study aimed to examine the cross-sectional association of non-standard employment with cardiovascular disease risk factors. Five yr of data from the Comprehensive Survey of Living Conditions and National Health and Nutritional Survey were combined. We used logistic regression to examine the association of employment contract (non-standard [part-time, dispatched, or contract] vs. standard [full-time and permanent]) with eight cardiovascular disease risk factors among 1,636 men and 2,067 women aged 40-60 yr. There were significant associations between non-standard employment and cardiovascular disease risk factors such as current smoking among men (odds ratio [OR] 1.39; 95% confidential interval [CI], 1.13-1.86) and diabetes among women (OR 1.83; 95% CI, 1.10-3.09). Non-standard employment was associated with a few cardiovascular disease risk factors in this middle-aged cohort in Japan.
