Purpose:
Thyroid transcription factor 1 (TTF-1) expression is a useful predictor of treatment efficacy in advanced non-squamous non–small cell lung cancer (NSCLC). This study aimed to evaluate whether TTF-1 could predict the effectiveness of chemotherapy versus chemoimmunotherapy in patients with non-squamous NSCLC with programmed death ligand-1 (PD-L1) expression between 1% and 49%.
Materials and Methods:
We conducted a retrospective study of patients with NSCLC who were treated with chemotherapy or chemoimmunotherapy between March 2016 and May 2023. The patients had histologically confirmed NSCLC, stage III-IV or postoperative recurrence, TTF-1 measurements, and PD-L1 expression levels between 1% and 49%. Clinical data were analyzed to evaluate the effect of TTF-1 expression on treatment efficacy.
Results:
This study included 283 of 624 patients. TTF-1–positive patients showed longer progression-free survival (PFS) and overall survival (OS) (PFS: 6.4 months [95% confidence interval (CI), 5.0 to 9.4] vs. 4.1 months [95% CI, 2.7 to 6.1], p=0.03; OS: 17.9 months [95% CI, 15.2 to 28.1] vs. 9.4 months [95% CI, 6.3 to 17.0], p < 0.01) in the chemotherapy cohorts (n=93). In the chemoimmunotherapy cohort (n=190), there was no significant difference in PFS and OS between TTF-1–positive and –negative groups (PFS: 7.6 months [95% CI, 6.4 to 11.0] vs. 6.0 months [95% CI, 3.6 to 12.6], p=0.59; OS: 25.0 months [95% CI, 18.0 to 49.2] vs. 21.3 months [95% CI, 9.8 to 28.8], p=0.09).
Conclusion
In patients with NSCLC with PD-L1 expression between 1% and 49%, TTF-1 expression was a predictor of chemotherapeutic, but not chemoimmunotherapeutic, efficacy.

Positive Deviance (PD) is based on the observation that in every community there are certain individuals or groups whose uncommon behaviors and strategies enable them to find better solutions to problems than their peers, while having access to the same resources and facing similar or worse challenges. Developed in 1990 by Save the Children to improve child nutrition in Vietnam, the PD approach has gained traction among development partners for various international development projects. This paper discusses how the PD approach and the Logical Framework Approach can be integrated in global health projects. The PD approach is effective for projects targeting behavior change, such as those aiming to improve nutrition, reduce infant mortality, promote reproductive health, and prevent non-communicable diseases. To integrate PD with the Logical Framework Approach, projects should create a logic model outlining inputs, activities, outputs, outcomes, and impacts. The PD approach should then be incorporated into each stage of this model. An objective that should be achieved through behavior change is defined as Outcome (Project Purpose), and Outputs need to be considered with the governance and the structure of the target societies and organizations as determinant factors for the dissemination of PD practices. Five steps of the PD implementation process, i.e., defining problems, identifying positive deviants, specifying and extracting PD practices, planning and implementing activities, and monitoring and evaluating, can be incorporated in the project as activities. Inputs should emphasize local initiatives, with experts playing supportive roles. While an increasing number of development partners for low- and middle-income countries have adopted the PD approach, such initiatives are still rare among Japanese organizations. The case presented demonstrates that even small-scale projects can yield significant results, encouraging Japanese colleagues to learn from this experience and consider how to initiate the challenge of applying the PD approach in future projects.

[Background] Moxibustion has contributed to better health outcomes of the Japanese people. But only a small number of reports are available regarding the current practice of moxibustion in recent years. We therefore surveyed moxibustion practitioners.[Methods] Through academic societies, professional organizations, and other associations related to the disciplines of acupuncture and moxibustion, practitioners were asked to respond to the questionnaire via Google Forms. [Results] Valid responses were obtained from 1,507 practitioners with the following demographics: 67.8% had been engaged in clinical practice for less than 20 years; 71.9% ran their own clinics; 43.6% belonged to academic societies; 69.3% belonged to industrial organizations, etc. The proportion of practitioners conducting various methods of moxibustion were as follows: 66.3% warming moxibustion and 53.4% for heating-through moxibustion, and regarding processed moxibustion, 79.5% included moxibustion with tube and 37.0% used smokeless moxibustion. Regarding the effectiveness of moxibustion, 98.9% responded as "highly effective" or "moderately effective." The proportion of respondents who experienced "patient's refusal of moxibustion" was 45.6% before patients experienced moxibustion and 33.2% after their experience. The patients refused it primarily because of "heat," "burns," and "uncomfortableness with smoke." Regarding the activities necessary to promote the spread of self-care moxibustion, "proving effectiveness through clinical research" (75.6%), "providing scientific evidence through basic research" (68.3%), and "awareness-building activities" (63.9%) were indicated among 1,495 respondents.[Discussion] The survey revealed that, due to the shift in societal awareness, there is also a shift in the use of moxibustion from direct moxibustion to more indirect moxibustion. Many clinical practitioners of moxibustion conducted the therapy because they considered it effective. The survey reconfirmed that heat, burns, and smoke represent major reasons why patients do not want to receive the moxibustion therapy. The challenging issues to be addressed for the purpose of spreading and developing moxibustion include maintenance of "safety," research to prove "clinical efficacy" and provide "scientific evidence," and "awareness-building activities."

In order for pharmacists to be collaboratively involved with patients in pharmacotherapy, there is a need to improve patients’ understanding of pharmacists’ involvement in extended pharmacotherapy, i.e., their interpersonal work. This study explores the factors that affect patients’ perceptions of pharmacists’ interpersonal work. A survey on patients’ perceptions of pharmacists’ interpersonal work was conducted among 450 patients aged 20 years or older who visited a pharmacy. Logistic regression analysis was performed with low and high patient perceptions of pharmacists’ interpersonal work as the objective variables. Valid responses were obtained from 350 participants. More than half of the respondents did not understand the nature of the interpersonal work of pharmacists. Patients who were unaware of pharmacists checking for side effects were more prevalent than those who were unaware of other interpersonal work. Explanations from the family pharmacist (OR=2.25, P=0.033) and trust in the pharmacist (OR=1.11, P=0.001) had a positive influence on patients’ perceptions of the pharmacist’s interpersonal tasks. As pharmacy pharmacists are increasingly becoming more involved with patients’ drug treatment and to ensure safe drug treatment practices for patients, it is considered important for pharmacists to actively explain their involvement in drug treatment to patients. This will be conducive to building trusting relationships, and for pharmacists to fulfil their function as family pharmacists.

Team-based learning (TBL) is an educational method developed to cultivate the ability to solve problems by learning and applying knowledge on one's own, as well as the ability to make decisions, take responsibility, and collaborate by working on issues in small groups. TBL in Kampo medicine was held as a special program : active learning at the 71st Annual Meeting of the Japan Society for Oriental Medicine. A total of 57 students participated in the TBL session. The theme of the session was the common cold with the theory of yin and yang. According to the results of a questionnaire survey, the students answered that they were able to understand the flow of diagnosis in Kampo medicine, which was the goal of the course. As a bridge from classroom lectures to clinical practice, TBL in Kampo medicine was considered to be useful in Kampo medical education.

BACKGROUND:
A protective role for physical activity against the development of atrial fibrillation (AF) has been suggested. Stair climbing is a readily available form of physical activity that many people practice. Herein, we investigated the association between stair climbing and the risk of AF in a Japanese population.
METHODS:
In this prospective cohort study, we used data of 6,575 people registered in the Suita Study, aged 30-84 years, and had no history of AF. The frequency of stair climbing was assessed by a baseline questionnaire, while AF was diagnosed during the follow-up using a 12-lead ECG, health records, check-ups, and death certificates. We used the Cox regression to calculate the hazard ratios and 95% confidence intervals of AF incidence for climbing stairs in 20-39%, 40-59%, and ≥60% compared with <20% of the time.
RESULTS:
Within 91,389 person-years of follow-up, 295 participants developed AF. The incidence of AF was distributed across the stair climbing groups <20%, 20-39%, 40-59%, and ≥60% as follows: 3.57, 3.27, 3.46, and 2.63/1,000 person-years, respectively. Stair climbing ≥60% of the time was associated with a reduced risk of AF after adjustment for age and sex 0.69 (0.49, 0.96). Further adjustment for lifestyle and medical history did not affect the results 0.69 (0.49, 0.98).
CONCLUSION
Frequent stair climbing could protect from AF. From a preventive point of view, stair climbing could be a simple way to reduce AF risk at the population level.

We evaluated decreases in glycosylated hemoglobin (HbA1c) achieved by reducing carbohydrate from various sources in type 2 diabetes mellitus patients. We followed up 138 male and 107 female outpatients on a moderate low-carbohydrate diet without diabetic medication for 6 months. Changes in carbohydrate sources (Δcarbohydrate) were assessed from 3-day dietary records at baseline and 6 months, and associations with changes in HbA1c (ΔHbA1c) were examined with Spearman's correlation coefficients ( ΔHbA1c was −1.5%±1.6% in men and −0.9%±1.3% in women, while Δtotal carbohydrate was −115.3±103.7 g/day in men and −63.6±71.1 g/day in women. Positive associations with ΔHbA1c were found for Δtotal carbohydrate ( Decreases in HbA1c achieved by reducing carbohydrate from soft drinks, confectionery, bread and Chinese soup noodles were 2- to 4-fold greater than that for rice. Our results will enable patients to decrease HbA1c efficiently (UMIN000009866).
