RESUMEN
A lack of adherence to long-term antiretroviral therapy may impact viral suppression. The current study examined the relationship between medication adherence and clinical outcomes in people with human immunodeficiency virus infection (PWH) receiving bictegravir, emtricitabine, and tenofovir alafenamide fumarate (B/F/TAF). A retrospective cohort study using two Japanese claims databases was conducted. Adherence was measured by the proportion of days covered (PDC). Patients were grouped into 3 PDC category and persistence was estimated by Kaplan-Meier method. Cox regression analysis was performed to investigate whether the PDC was associated with treatment discontinuation. Among 952 patients, 820 (86.1%), 95 (10.0%), and 37 (3.9%) patients were grouped into the PDC ≥ 90%, 80- < 90%, and < 80% groups, respectively. Across all PDC groups, more than 90% of patients who received B/F/TAF were receiving treatment at 1 year. There was no significant difference in the risk of discontinuation between the lower PDC groups (80- < 90% and < 80%) and the PDC ≥ 90% group (0.400 [0.096, 1.661]; 2.244 [0.663, 7.594], hazard ratio [95% confidence interval], respectively). A drug resistance test was implemented for 15 patients, none of whom discontinued B/F/TAF after the test. The results suggest that events that could cause discontinuation, such as virologic failure, were not associated with PDC.

Emotions are fundamental to social interaction and deeply intertwined with interpersonal dynamics, especially in romantic relationships. Although the neural basis of interaction processes in romance has been widely explored, the underlying emotions and the connection between relationship quality and neural synchronization remain less understood. Our study employed EEG hyperscanning during a non-interactive video-watching paradigm to compare the emotional coordination between romantic couples and close friends. Couples showed significantly greater behavioral and prefrontal alpha synchronization than friends. Notably, couples with low relationship quality required heightened neural synchronization to maintain robust behavioral synchronization. Further support vector machine analysis underscores the crucial role of prefrontal activity in differentiating couples from friends. In summary, our research addresses gaps concerning how intrinsic emotions linked to relationship quality influence neural and behavioral synchronization by investigating a natural non-interactive context, thereby advancing our understanding of the neural mechanisms underlying emotional coordination in romantic relationships.

INTRODUCTION: Long-term medication leads some people with HIV (PWH) to limited treatment options (LTO) due to multiple factors. The present study investigated the prevalence of PWH with LTO in Japan and their clinical characteristics, persistence, and adherence. METHODS: PWH who received antiretroviral therapy (ART) between 2017 and 2022 were identified in the Medical Data Vision (MDV) Japanese claims database. PWH with LTO were defined as: 1) receiving regimens indicative for LTO or 2) having a complex treatment history (≥4 different core agents, ≥11 ART agents). Prevalence by calendar year, clinical characteristics, persistence, and adherence measured by the proportion of days covered (PDC) of ART were investigated. RESULTS: A total of 5740 PWH were included, and 207 (3.6 %) were identified as LTO. Mean (SD) age was 50.3 (11.8) years, 148 (71.5 %) had evidence of AIDS-defining condition, and 25 (12.1 %) had hemophilia. The prevalence of PWH with LTO increased from 2.58 % in 2017 to 3.55 % in 2022. Persistence at 1 year was estimated as 70.3 % and mean PDC through 1 year was 96.7 %. CONCLUSION: Between the years 2017-2022, 3.6 % (approximately 200) Japanese PWH were identified as having LTO. The results of this analysis found clinical characteristics of PWH with LTO as older age and higher percentages with an AIDS-defining condition and hemophilia than the general HIV population. Low persistence indicates that treatment optimization is required in this population. These results will help health care providers to understand the clinical characteristics of PWH with LTO and may contribute to the establishment of appropriate treatment strategies.
RESUMEN
INTRODUCTION: Although patients with HBV have a risk of reactivation after immunosuppressive therapy (IST), the status of their risk management is unclear in Japan. This study aims to describe the proportion of patients who received preventive management of HBV reactivation during ISTs in patients with chronic HBV infection of HBsAg or resolved HBV infection. METHOD: A retrospective cohort study was conducted using the JMDC Japanese claims database from April 2011 to June 2021. Patients with HBV infections of HbsAg who received ISTs or patients who had resolved HBV infections who received ISTs were identified from the database and evaluated for appropriate management to prevent HBV reactivation. RESULTS: In total, 6242 eligible patients were identified. The proportions of patients with appropriate HBV reactivation management, stratified by the HBV reactivation risk level of IST, was 43.1% (276/641) for high-risk, 40.2% (223/555) for intermediate-risk and 14.9% (741/4965) for low-risk patients. When the evaluation period for the outcome calculation was shortened from 360 to 180 days, the proportion for high risk increased to 52.7%. The odds ratios of large hospitals for receiving appropriate management were 2.16 (95% CI 1.12-4.44) in the high-risk, 4.63 (95% CI 2.34-10.25) in the intermediate-risk and 3.60 (95% CI 3.07-4.24) in the low-risk patients. CONCLUSION: HBV reactivation management was tailored according to the reactivation risk associated with IST. However, adherence to HBV reactivation management guidelines was sub-optimal, even among high-risk patients. This is especially the case for ensuring smaller-sized medical institutions, highlighting the need for further educational activities.
The study assesses the implementation of guideline-based management of hepatitis B virus reactivation during immunosuppressive therapy in Japan. The appropriate management of hepatitis B virus treatment involves prophylactic nucleos(t)ide analog (NUC) therapy and regular monitoring of hepatitis B virus DNA. This study aims to assess the extent to which these management practices are implemented in a clinical setting in Japan using a retrospective cohort study using the Japanese Medical Claims Database. The analysis identified 6242 eligible patients and identified whether they received appropriate management to prevent hepatitis B virus reactivation based on the level of risk associated with their immunosuppressive therapy. Based on the guidelines, the proportions of patients receiving appropriate reactivation management were 43.1% for high-risk, 40.2% for intermediate-risk and 14.9% for low-risk immunosuppressive therapy patients. Shortening the evaluation period from 360 to 180 days showed an increase in the proportion of high-risk patients to 52.7%, which indicated the potential challenge for continued monitoring after immunosuppressive therapy administration. The study shows that large hospitals present higher odds of patients receiving appropriate management. Overall, adherence to hepatitis B virus reactivation management guidelines was suboptimal, especially in smaller medical institutions, emphasizing the need for additional educational activities.
RESUMEN
PURPOSE: This study evaluated treatment patterns and clinical outcomes among patients with metastatic triple-negative breast cancer (mTNBC) in real-world clinical settings in Japan. METHODS: The treatment patterns, time to next treatment or death (TTNTD), time to treatment discontinuation, adverse events of interest, and medical costs of treating patients with mTNBC in first-, second-, and third-line settings were investigated using data of patients meeting the inclusion criteria between January 2017 and March 2022 in a Japanese medical claims database. The treatment regimens for mTNBC were defined according to the Japanese Breast Cancer Society Clinical Practice Guidelines. RESULTS: In this study, 2236 patients with mTNBC (median age 66.0 years; 99.8% female) were included in the first-line cohort. Of these, 46.6% and 20.8% were included in the second- and third-line cohorts, respectively. The two most frequently used treatments were capecitabine (19.1%) and S-1 (tegafur-gimeracil-oteracil) (14.5%) in the first-line cohort, eribulin (18.3%) and bevacizumab/paclitaxel (14.4%) in the second-line cohort, and eribulin (19.4%) and bevacizumab/paclitaxel (17.5%) in the third-line cohort. The TTNTD shortened as the line of therapy progressed (median 8.0, 6.5, and 5.2 months for the first-, second-, and third-line treatments, respectively). Nausea/vomiting and neutropenia/leukopenia occurred in 62.8% and 18.3% of all patients, respectively. The medical total costs per day were 6.7, 10.2, and 12.9 thousand yen during the first-/second-/third-line treatments, respectively. CONCLUSION: This study provides insight into current treatment patterns for mTNBC in Japan. The cost-benefit balance worsens with later-line treatment and a high unmet need for mTNBC drug treatment remains.

Given the increasing presence of robots in everyday environments and the significant challenge posed by social interactions with robots, it is crucial to gain a deeper understanding into the social evaluations of robots. One potentially effective approach to comprehend the fundamental processes underlying controlled and automatic evaluations of robots is to probe brain response to different perception levels of robot-related stimuli. Here, we investigate controlled and automatic evaluations of robots based on brain responses during viewing of suprathreshold (duration: 200 ms) and subthreshold (duration: 17 ms) humanoid robot stimuli. Our behavioral analysis revealed that despite participants' self-reported positive attitudes, they held negative implicit attitudes toward humanoid robots. Neuroimaging analysis indicated that subthreshold presentation of humanoid robot stimuli elicited significant activation in the left amygdala, which was associated with negative implicit attitudes. Conversely, no significant left amygdala activation was observed during suprathreshold presentation. Following successful attenuation of negative attitudes, the left amygdala response to subthreshold presentation of humanoid robot stimuli decreased, and this decrease correlated positively with the reduction in negative attitudes. These findings provide evidence for separable patterns of amygdala activation between controlled and automatic processing of robots, suggesting that controlled evaluations may influence automatic evaluations of robots.

Background: Human immunodeficiency virus (HIV) screeners have limited experience of interacting with trans people. The application of communication platforms between them to empower HIV screeners' trans-related cultural competence remains unknown. Objective: This study aims to qualitatively explore the follow-up interviews of HIV screeners regarding their opinions on the feasibility of an online platform group discussion and web page to enhance communication between them and trans people and to explore their perspectives on how these components enhanced their promotion of cultural competence. Methods: This study was conducted between October 2020 and June 2021. Purposive and snowball sampling were applied to recruit 6 trans persons and 11 HIV screeners. Six online platform group discussions were held on weekday evenings, each group meeting for 60â min, 360â min in total within 3 months, via a video chat room of Google Meet; this was supplemented by a closed web page. The major results were presented through content analysis of the HIV screeners' follow-up interviews. Results: The HIV screeners identified the facilitators of participating in the communication platforms, which included a reminder message, easy-to-use interface, visible-audible and readable interaction, recalled and reviewable content and group belonging; the barriers included time and space limitation, device restrictions and operation problem. Two categories of trans-related cultural competence - trans awareness and action taken - were revealed, from which five major themes emerged: provoked to ask questions, improved cognition, reflection, trans-sensitive communication and self-enhancement. Conclusion: The results revealed that the communication platforms could facilitate the mutual and vivid discussion between HIV screeners and trans people and empower the trans-related cultural competence of HIV screeners. The highly feasible intervention design of this research can be applied to digital training courses related to gender diversity issues.
RESUMEN
ABSTRACT: The right ventricular fetal tricuspid annular plane systolic excursion index (FTI) can be used to evaluate right ventricular systolic function. The purpose of this study was to establish the reference range of the FTI in normal fetuses and evaluate its diagnostic value in hypertensive disorders during pregnancy. In this prospective observational study, the right ventricular FTI was measured in 208 normal single-gestation fetuses between 20 and 40 weeks. With the increase in gestational age, the right ventricular FTI did not significantly fluctuate. With the increase in the severity of HDCP, the right ventricular FTI decreased gradually. Compared with the normal group, the low right ventricular FTI group had a higher incidence of premature delivery and emergency delivery due to continuous abnormal fetal heart monitoring, but there were no significant differences in low birth weight, new born Apgar score less than 7 in 5 minutes, or admission to the neonatal intensive care unit. The FTI of the right ventricle of normal fetuses is relatively constant at different gestational weeks. The right ventricular FTI can be used to evaluate fetal cardiac function changes in pregnant women with HDCP.
RESUMEN
BACKGROUND: Recently, attention has focused on the impact of global climate change on infectious diseases. Storm flooding is an extreme weather phenomenon that not only impacts the health of the environment but also worsens the spread of pathogens. This poses a significant challenge to public health security. However, there is still a lack of research on how different levels of storm flooding affect susceptible enteric infectious diseases over time. METHODS: Data on enteric infectious diseases, storm flooding events, and meteorology were collected for Changsha, Hunan Province, between 2016 and 2020. The Wilcoxon Rank Sum Test was used to identify the enteric infectious diseases that are susceptible to storm flooding. Then, the lagged effects of different levels of storm flooding on susceptible enteric infectious diseases were analyzed using a distributed lag nonlinear model. RESULTS: There were eleven storm flooding events in Changsha from 2016 to 2020, concentrated in June and July. 37,882 cases of enteric infectious diseases were reported. During non-flooding days, the daily incidence rates of typhoid/paratyphoid and bacillary dysentery were 0.3/100,000 and 0.1/100,000, respectively. During flooding days, the corresponding rates increased to 2.0/100,000 and 0.8/100,000, respectively. The incidence rates of both diseases showed statistically significant differences between non-flooding and flooding days. Correlation analysis shows that the best lags for typhoid/paratyphoid and bacillary dysentery relative to storm flooding events may be 1 and 3 days. The results of the distributed lag nonlinear model showed that typhoid/paratyphoid had the highest cumulative RR values of 2.86 (95% CI: 1.71-4.76) and 8.16 (95% CI: 2.93-22.67) after 4 days of general flooding and heavy flooding, respectively; and bacillary dysentery had the highest cumulative RR values of 1.82 (95% CI: 1.40-2.35) and 3.31 (95% CI: 1.97-5.55) after 5 days of general flooding and heavy flooding, respectively. CONCLUSIONS: Typhoid/paratyphoid and bacillary dysentery are sensitive enteric infectious diseases related to storm flooding in Changsha. There is a lagging effect of storm flooding on the onset of typhoid/paratyphoid and bacillary dysentery, with the best lagging periods being days 1 and 3, respectively. The cumulative risk of typhoid/paratyphoid and bacillary dysentery was highest at 4/5 days lag, respectively. The higher of storm flooding, the higher the risk of disease, which suggests that the authorities should take appropriate preventive and control measures before and after storm flooding.

Background: Internet gaming disorder (IGD) is a mental health issue that affects individuals worldwide. However, the lack of knowledge about the biomarkers associated with the development of IGD has restricted the diagnosis and treatment of this disorder. Aims: We aimed to reveal the biomarkers associated with the development of IGD through resting-state brain network analysis and provide clues for the diagnosis and treatment of IGD. Methods: Twenty-six patients with IGD, 23 excessive internet game users (EIUs) who recurrently played internet games but were not diagnosed with IGD and 29 healthy controls (HCs) performed delay discounting task (DDT) and Iowa gambling task (IGT). Resting-state functional magnetic resonance imaging (fMRI) data were also collected. Results: Patients with IGD exhibited significantly lower hubness in the right medial orbital part of the superior frontal gyrus (ORBsupmed) than both the EIU and the HC groups. Additionally, the hubness of the right ORBsupmed was found to be positively correlated with the highest excessive internet gaming degree during the past year in the EIU group but not the IGD group; this might be the protective mechanism that prevents EIUs from becoming addicted to internet games. Moreover, the hubness of the right ORBsupmed was found to be related to the treatment outcome of patients with IGD, with higher hubness of this region indicating better recovery when undergoing forced abstinence. Further modelling analysis of the DDT and IGT showed that patients with IGD displayed higher impulsivity during the decision-making process, and impulsivity-related parameters were negatively correlated with the hubness of right ORBsupmed. Conclusions: Our findings revealed that the impulsivity-related right ORBsupmed hubness could serve as a potential biomarker of IGD and provide clues for the diagnosis and treatment of IGD.
RESUMEN
BACKGROUND: While global efforts have been made to prevent transmission of HIV, the epidemic persists. Men who have sex with men (MSM) are at high risk of infection. Despite evidence of its cost-effectiveness in other jurisdictions, pre-exposure prophylaxis (PrEP) for MSM is neither approved nor reimbursed in Japan. METHOD: The cost-effectiveness analysis compared the use of once daily PrEP versus no PrEP among MSM over a 30-year time horizon from a national healthcare perspective. Epidemiological estimates for each of the 47 prefectures informed the model. Costs included HIV/AIDS treatment, HIV and testing for sexually transmitted infections, monitoring tests and consults, and hospitalization costs. Analyses included health and cost outcomes, as well as the incremental cost-effectiveness ratio (ICER) reported as the cost per quality-adjusted life year (QALY) for all of Japan and each prefecture. Sensitivity analyses were performed. FINDINGS: The estimated proportion of HIV infections prevented with the use of PrEP ranged from 48% to 69% across Japan, over the time horizon. Cost savings due to lower monitoring costs and general medical costs were observed. Assuming 100% coverage, for Japan overall, daily use of PrEP costs less and was more effective; daily use of PrEP was cost-effective at a willingness to pay threshold of ¥5,000,000 per QALY in 32 of the 47 prefectures. Sensitivity analyses found that the ICER was most sensitive to the cost of PrEP. INTERPRETATION: Compared to no PrEP use, once daily PrEP is a cost-effective strategy in Japanese MSM, reducing the clinical and economic burden associated with HIV.
HIV remains an epidemic, and men who have sex with men (MSM) are at higher risk of infection. Pre-exposure prophylaxis (PrEP) is a preventive treatment that can reduce someone's risk of getting infected with HIV and has been shown to provide good value for money. PrEP, however, is neither approved nor reimbursed in Japan. In order to determine the value for money in Japan, an economic model was developed to estimate the number of HIV infections and AIDS cases that could be avoided, along with whether daily use of PrEP among MSM in Japan is cost effective. Findings showed that with use of daily PrEP, the proportion of HIV infections and AIDS cases prevented was 63% and 59%, respectively, across Japan. Over a 30-year time horizon, daily use of PrEP would cost the health system less and be more effective than no use of PrEP. Daily PrEP should therefore be considered for reimbursement in MSM in Japan, given its value for money.

BACKGROUND: Mobile voluntary counseling and testing (VCT) for HIV has been carried out to improve the targeting of at-risk populations and HIV case detection for men who have sex with men (MSM). However, the HIV-positive detection rate using this screening strategy has declined in recent years. This may imply unknown changes in risk-taking and protective features jointly influencing the testing results. These changing patterns in this key population remain unexplored. OBJECTIVE: The aim of this study was to identify the nuanced group classification of MSM who underwent mobile VCT using latent class analysis (LCA), and to compare the difference in characteristics and testing results between subgroups. METHODS: A cross-sectional research design and purposive sampling were applied between May 21, 2019, and December 31, 2019. Participants were recruited by a well-trained research assistant through social networking platforms, including the most popular instant messenger app Line, geosocial network apps dedicated to MSM, and online communities. Mobile VCT was provided to participants at an assigned time and place. Demographic characteristics and risk-taking and protective features of the MSM were collected via online questionnaires. LCA was used to identify discrete subgroups based on four risk-taking indicators-multiple sexual partners (MSP), unprotected anal intercourse (UAI), recreational drug use within the past 3 months, and history of sexually transmitted diseases-and three protective indicators-experience of postexposure prophylaxis, preexposure prophylaxis use, and regular HIV testing. RESULTS: Overall, 1018 participants (mean age 30.17, SD 7.29 years) were included. A three-class model provided the best fit. Classes 1, 2, and 3 corresponded to the highest risk (n=175, 17.19%), highest protection (n=121, 11.89%), and low risk and low protection (n=722, 70.92%), respectively. Compared to those of class 3, class 1 participants were more likely to have MSP and UAI within the past 3 months, to be ≥40 years of age (odds ratio [OR] 2.197, 95% CI 1.357-3.558; P=.001), to have HIV-positive results (OR 6.47, 95% CI 2.272-18.482; P<.001), and a CD4 count ≤349/µL (OR 17.50, 95% CI 1.223-250.357; P=.04). Class 2 participants were more likely to adopt biomedical preventions and have marital experience (OR 2.55, 95% CI 1.033-6.277; P=.04). CONCLUSIONS: LCA helped derive a classification of risk-taking and protection subgroups among MSM who underwent mobile VCT. These results may inform policies for simplifying the prescreening assessment and more precisely recognizing those who have higher probabilities of risk-taking features but remain undiagnosed targets, including MSM engaging in MSP and UAI within the past 3 months and those ≥40 years old. These results could be applied to tailor HIV prevention and testing programs.

Natural language processing (NLP) is central to the communication with machines and among ourselves, and NLP research field has long sought to produce human-quality language. Identification of informative criteria for measuring NLP-produced language quality will support development of ever-better NLP tools. The authors hypothesize that mentalizing network neural activity may be used to distinguish NLP-produced language from human-produced language, even for cases where human judges cannot subjectively distinguish the language source. Using the social chatbots Google Meena in English and Microsoft XiaoIce in Chinese to generate NLP-produced language, behavioral tests which reveal that variance of personality perceived from chatbot chats is larger than for human chats are conducted, suggesting that chatbot language usage patterns are not stable. Using an identity rating task with functional magnetic resonance imaging, neuroimaging analyses which reveal distinct patterns of brain activity in the mentalizing network including the DMPFC and rTPJ in response to chatbot versus human chats that cannot be distinguished subjectively are conducted. This study illustrates a promising empirical basis for measuring the quality of NLP-produced language: adding a judge's implicit perception as an additional criterion.

The enzyme flavone synthase Is (FNS Is) converts flavanones to flavones, whereas flavanone 3ß-hydroxylases (F3Hs) catalyze the formation of dihydroflavonols, a precursor of flavonols and anthocyanins. Canonical F3Hs have been characterized in seed plants, which are evolutionarily related to liverwort FNS Is. However, as important evolutionary lineages between liverworts and seed plants, ferns FNS Is and F3Hs have not been identified. In the present study, we characterized a bifunctional enzyme PnFNS I/F3H from the fern Psilotum nudum. We found that PnFNS I/F3H catalyzed the conversion of naringenin to apigenin and dihydrokaempferol. In addition, it catalyzed five different flavanones to generate the corresponding flavones. Site-directed mutagenesis results indicated that the P228-Y228 mutant protein displayed the FNS I/F2H activity (catalyzing naringenin to generate apigenin and 2-hydroxynaringenin), thus having similar functions as liverwort FNS I/F2H. Moreover, the overexpression of PnFNS I/F3H in Arabidopsis tt6 and dmr6 mutants increased the content of flavones and flavonols in plants, further indicating that PnFNS I/F3H showed FNS I and F3H activities in planta. This is the first study to characterize a bifunctional enzyme FNS I/F3H in ferns. The functional transition from FNS I/F3H to FNS I/F2H will be helpful in further elucidating the relationship between angiosperm F3Hs and liverwort FNS Is.

Temporal interference transcranial alternating current stimulation (TI-tACS) is a new technique of noninvasive brain stimulation. Previous studies have shown the effectiveness of TI-tACS in stimulating brain areas in a selective manner. However, its safety in modulating human brain neurons is still untested. In this study, 38 healthy adults were recruited to undergo a series of neurological and neuropsychological measurements regarding safety concerns before and after active (2 mA, 20/70 Hz, 30 min) or sham (0 mA, 0 Hz, 30 min) TI-tACS. The neurological and neuropsychological measurements included electroencephalography (EEG), serum neuron-specific enolase (NSE), the Montreal Cognitive Assessment (MoCA), the Purdue Pegboard Test (PPT), an abbreviated version of the California Computerized Assessment Package (A-CalCAP), a revised version of the Visual Analog Mood Scale (VAMS-R), a self-assessment scale (SAS), and a questionnaire about adverse effects (AEs). We found no significant difference between the measurements of the active and sham TI-tACS groups. Meanwhile, no serious or intolerable adverse effects were reported or observed in the active stimulation group of 19 participants. These results support that TI-tACS is safe and tolerable in terms of neurological and neuropsychological functions and adverse effects for use in human brain stimulation studies under typical transcranial electric stimulation (TES) conditions (2 mA, 20/70 Hz, 30 min).
RESUMEN
OBJECTIVES: To investigate current patterns and outcomes of intravesical bacillus Calmette-Guérin treatment in Japanese patients with bladder cancer, including the proportion of patients completing induction therapy, and time to subsequent treatments. METHODS: This retrospective cohort study utilized administrative claims data from the Medical Data Vision Co., Ltd. database to identify patients with a diagnosis of bladder cancer who had received ≥1 prescription of intravesical bacillus Calmette-Guérin between April 2008 and September 2015, and had ≥1 database record dated ≥12 weeks after the initial bacillus Calmette-Guérin dose. Patients were followed until September 2018, the last date of available data, or in-hospital death. Patients receiving six doses of bacillus Calmette-Guérin at intervals of <21 days were considered to have completed induction according to guidelines. Time from initial bacillus Calmette-Guérin dose to subsequent bladder cancer treatment after the end of treatment was defined as the recurrence-free duration. RESULTS: Of 6140 patients identified (median age 73.0 years; 83.4% males), 4588 (74.7%) completed induction and 1552 (25.3%) did not. Median recurrence-free duration was 64.4, 77.7, and 31.6 months in the overall, complete-induction and incomplete-induction cohorts, respectively. Corresponding 3-year recurrence-free rate was 56.3%, 59.0%, and 48.2% in these groups. The rate of cystectomy was approximately 6% at 5 years in all cohorts. CONCLUSIONS: Approximately 75% of Japanese patients who undergo intravesical bacillus Calmette-Guérin treatment receive a guideline-compliant induction regimen, but outcomes were not satisfactory, highlighting the need for more effective treatments for non-muscle invasive bladder cancer.

BACKGROUND: Men who have sex with men (MSM) who undergo voluntary HIV counseling and testing (VCT) often report condomless anal sexual intercourse, having many sexual partners, and being exposed to risky sexual networks. Limited research has discussed the application of motivational interviewing and convenience referral platforms to facilitate the referral of sexual partners for HIV testing among MSM. OBJECTIVE: This study aimed to evaluate the effects of VCT referral by sexual partners through social networking platforms and the test results after elicited interviews with MSM; compare the characteristics and risk behaviors among MSM tested without referral, index subjects, and referred sexual partners; and explore unknown sexual affiliations through visualizing and quantifying the social network graph. METHODS: This was a cross-sectional study. Purposeful sampling was used to recruit index subjects from a community HIV screening station frequented by MSM in Taipei City on Friday and Saturday nights. Respondent-driven sampling was used to recruit sexual partners. Partner-elicited interviews were conducted by trained staff before VCT to motivate MSM to become index subjects and refer sexual partners via the Line app, or to disclose the accounts and profiles of sexual partners on relevant social networking platforms. Referred sexual partners received rapid HIV testing, and the recruitment process was repeated until leads were exhausted. RESULTS: After the interviews, 28.2% (75/266) of MSM were successfully persuaded to become index subjects in the first wave, referring 127 sexual partners via the Line app for rapid HIV testing and disclosing 40 sexual partners. The index subjects and tested sexual partners had more sexual partners (F2=3.83, P=.02), more frequent anal intercourse (F2=10.10, P<.001), and higher percentages of those who had not previously received HIV testing (χ21=6.1, P=.047) compared with MSM tested without referrals. The new HIV-seropositivity rate among tested sexual partners was 2.4%, which was higher than the rate in the other 2 groups. The social network analysis revealed the following 4 types of sexual affiliation: chain, Y, star, and complicated. Among the HIV-negative sexual partners, 26.9% (43/160) had sexual affiliations with HIV-positive nodes, and 40% (10/25) were untested sexual partners with a direct sexual affiliation with an HIV-positive node. Four transmission bridges were found in the network graph. CONCLUSIONS: Partner-elicited interviews can effectively promote referral for HIV testing and case identification via Line, and can clarify unknown sexual affiliations of MSM to facilitate the development of a tailored prevention program. Social network analysis is needed for an insightful understanding of the different network structures.

BACKGROUND: In Japan, regional differences in asthma mortality have been reported; however, regional differences in asthma exacerbations have not been studied extensively. Therefore, using a health insurance claims database, we investigated the regional differences in the incidence of asthma exacerbations in Japan. METHODS: This study used data from Medi-Scope (Japan Medical Information Research Institute Inc., Japan)-a nationwide health insurance claims database. Patients with asthma at the index date (the latest date of an asthma-related prescription with an asthma diagnosis before October 1, 2018) were included in the analysis. The pre-index period was defined as 1 year before the index date, and the follow-up period as 1 year after the index date. The incidence of asthma exacerbation events was analyzed for each region. RESULTS: The primary analysis population comprised 24,883 patients who were continuously prescribed ICS or ICS/LABA at least four times during the pre-index period. The incidence rate of asthma exacerbations with hospitalization was the highest in Chugoku (2.95/100 person-years [95% CI, 1.97-4.43]) and the lowest in Kanto (1.52/100 person-years [95% CI, 1.26-1.83]). The incidence rate of asthma exacerbations for the composite outcome of hospitalization, injectable corticosteroid prescription, and oral corticosteroid burst was the highest in Fukui (105.00/100 person-years [95% CI, 64.53-170.85]) and the lowest in Nagasaki (15.69/100 person-years [95% CI, 10.84-22.72]). CONCLUSIONS: Regional differences in the incidence of asthma exacerbations as well as their treatments were observed in Japan.

According to the cognitive model of depression, memory bias, interpretation bias, and attention bias are associated with the development and maintenance of depression. Here, we present a protocol for investigating whether and how the novel coronavirus disease 2019 (COVID-19) pandemic may affect the relationship between current cognitive biases and future depression severity in a population with non-clinical depression. This protocol can also be used in other contexts, including cognitive bias-related studies and depression-related functional magnetic resonance imaging (fMRI) studies. For complete details on the use and execution of this protocol, please refer to Zhang et al. (2021).

Because of the impact of close partner's touch on psychological and physical well-being by alleviating stress, it is important to explore the influence factors that underlie the stress-alleviating effect of close partner's touch. Previous studies suggested that the stress-alleviating effect was different when individuals were touched by different persons. Specifically, the stress was reduced significantly when the individual was touched by the close partner compared with the acquaintance and the stranger. However, whether the stress-alleviating effect of touch was modulated by the close relationship quality is unknown. To examine this question, the participants (n = 61) performed a 3 (i.e., alone, partner no-touch, and partner touch) × 2 (i.e., safety and threat) within-subjects experiment. The results revealed that the stress of the participants alleviated significantly while close partners present with touch compared with without touch during facing a threat. We also found that the relationship quality of couple-members (i.e., participants perceiving the quality of alternatives and the partners' commitment level) modulated touch-induced stress alleviation. Participants perceiving the low quality of alternatives and the high partners' commitment level showed stronger touch-induced stress-alleviating effect than participants perceiving the high quality of alternatives and the low partners' commitment level. The explained variance was around 16.8% jointly for actor and partner effects. These findings provide evidence for explaining the reasons for touch-induced alleviating stress and have important implications for predicting the future effect of interactive behaviors.
