Family history of lung cancer (FHLC) has been widely studied but most prospective cohort studies have primarily been conducted in non-Asian countries. We assessed the association between FHLC with risk of lung cancer (LC) incidence and mortality in a population of East Asian individuals. A total of 478,354 participants from 11 population-based cohorts in the Asia Cohort Consortium were included. A Cox proportional hazards regression model was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). A total of 7,785 LC incident cases were identified. FHLC (any LC subtype) was associated with an increased risk of LC incidence (HR = 1.45, 95% CI = 1.30-1.63). The positive association was observed in men and women (HR = 1.44, 95% CI = 1.26-1.66 in men; HR = 1.47, 95% CI = 1.22-1.79 in women), and in both never-smokers and ever-smokers (HR = 1.43, 95% CI = 1.18-1.73 in never-smokers; HR = 1.46, 95% CI =1.27-1.67 in ever-smokers). FHLC was associated with an increased risk of lung adenocarcinoma (HR = 1.63, 95% CI: 1.36-1. 94), squamous cell carcinoma (HR = 1.88, 95% CI: 1.46-2.44), and other non-small cell LC (HR = 1.94, 95% CI: 1.02-3.68). However, we found no evidence of significant effect modification by sex, smoking status, and ethnic groups. In conclusion, FHLC was associated with increased risk of LC incidence and mortality, and the associations remained consistent regardless of sex, smoking status and ethnic groups among the East Asian population., (© 2024 The Author(s).

Background : Income is a key determinant of well-being; however, its effects are often nonlinear. In Japan, working women face unique limitations to their well-being, including substantial gender wage gaps, caregiving responsibilities, and female-specific health conditions. This study aimed to investigate the association between income and well-being, with a focus on potential nonlinear patterns and effect modification with various factors. Methods : A nationwide survey of 10,000 working women aged 20-64 years was conducted in Japan in 2023. Well-being was assessed using four items from the Office for National Statistics-4 questionnaire, each rated on a 0-10 Likert scale. Tobit regression models were used to assess the association between household income and well-being after adjusting for demographic, socioeconomic, and health-related factors. Results : Annual household income was positively associated with well-being in women earning up to 8-10 million JPY annually, beyond which the effect was attenuated. Women with mental health issues or insomnia reported significantly lower well-being scores regardless of their income level ( p < 0.05). Marital status and caregiving responsibilities had moderate effects, whereas having more children diminished the positive effect of income among higher-income households earning over 8 million JPY annually. Conclusions : This study highlights the need for integrated policies that address both economic disparities and health-related challenges to improve the well-being of working women in Japan. Targeted interventions focusing on female-specific health conditions are particularly important.

Given the female predominance of thyroid cancer (TC), particularly in the reproductive age range, female sex hormones have been proposed as an aetiology; however, previous epidemiological studies have shown conflicting results. We conducted a pooled analysis using individual data from 9 prospective cohorts in the Asia Cohort Consortium, to explore the association between 10 female reproductive and hormonal factors and TC risk. Using Cox proportional hazards models, cohort-specific hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated and then pooled using a random-effects model. Analyses were stratified by country, birth years, smoking status, body mass index, and TC risk based on age of diagnosis was also examined. Among 259,649 women followed for a mean 17.2 years, 1,353 incident TC cases were identified, 88% (n=1,140) being papillary TC. Older age at first delivery (≥26 vs 21-25 years) was associated with increased TC risk (p-trend=0.003, HR=1.16, 95% CI:1.03-1.31), particularly when diagnosed later in life (≥55 vs <55 years) [p-trend=0.003; HR=1.19, 95% CI:1.02-1.39]. Among younger birth cohorts, women with more number of deliveries showed an increased TC risk [p-trend=0.0001, HR=2.40, 95% CI:1.12-5.18 (≥5 vs 1-2 children)], and there was no substantial trend in older cohorts. Distinct patterns were observed for the number of deliveries and TC risk across countries, with a significant positive association for Korea [p-trend=0.0008, HR=1.89, 95% CI:1.21-2.94 (≥5 vs 1-2 children)], and non-significant inverse associations for China and Japan. Contextual and macrosocial changes in reproductive factors in Asian countries may influence thyroid cancer risk.

Measurement-based care (MBC) has not been routinely incorporated into the inpatient setting in child and adolescent psychiatry. This article discusses who should be measuring the outcomes and what needs to be considered in selecting outcome measurement scales in the inpatient setting. Characteristics of inpatient populations may pose challenges in selecting appropriate measurements to track outcomes. However, even young patients and patients with psychosis can contribute to the MBC. This article also discusses barriers and possible solutions for implementing MBC in the inpatient setting., Competing Interests: Disclosure Dr E.

Objectives: To evaluate changes in the age at menarche in Asian populations., Study Design: Retrospective cohort study., Methods: We included 548,830 women from six countries in Asia. The data were sourced from 20 cohorts participating in the Asia Cohort Consortium (ACC) and two additional cohort studies: Japan Multi-institutional Collaborative Cohorts (J-MICC), and Japan Nurse Health Study (JNHS) with data on age at menarche. Joinpoint regression was used to evaluate changes in age at menarche by birth year and by country., Results: The study includes data from cohorts in six Asian countries namely, China, Iran, Japan, Korea, Malaysia and Singapore. Birth cohorts ranged from 1873 to 1995. The mean age of menarche was 14.0 years with a standard deviation (SD) of 1.4 years, ranged from 12.6 to 15.5 years. Over 100 years age at menarche showed an overall decrease in all six countries. China showed a mixed pattern of decrease, increase, and subsequent decrease from 1926 to 1960. Iran and Malaysia experienced a sharp decline between about 1985 and 1990, with APC values of -4.48 and -1.24, respectively, while Japan, South Korea, and Singapore exhibited a nearly linear decline since the 1980s, notably with an APC of -3.41 in Singapore from 1993 to 1995., Conclusions: Overall, we observed a declining age at menarche, while the pace of the change differed by country. Additional long-term observation is needed to examine the contributing factors of differences in trend across Asian countries. The study could serve as a tool to strengthen global health campaigns., (Copyright © 2024 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.)

Aim: To assess the cost-effectiveness of diabetic nephropathy treatment with sodium-glucose cotransporter-2 (SGLT2) inhibitors in Japanese clinical practice, considering diabetes-related complications., Materials and Methods: A population-based Monte Carlo simulation was used to estimate the cost-effectiveness for people with diabetic nephropathy who initiated pharmacotherapy with an SGLT2 inhibitor plus conventional treatment or conventional treatment alone, based on quality-adjusted life-years (QALYs) and healthcare costs. The Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation study (CREDENCE) and the Japanese Society for Dialysis Research statistical survey were the primary sources of probability and mortality, while Japanese Health Insurance Claims Data were the cost source. The state transition model included diabetic nephropathy, hospitalization due to cardiovascular disease, dialysis, and death. One-way and probabilistic sensitivity analyses were used to explore model uncertainty., Results: Using the threshold of JPY 5 000 000 per QALY, SGLT2 inhibitor plus conventional treatment was more cost-effective than conventional treatment alone, with an incremental cost-effectiveness ratio of JPY 654 309 per QALY. Treating 100 000 people, SGLT2 inhibitor plus conventional treatment prevented 2234 deaths and reduced 5793 fewer heart failure cases, 3967 fewer myocardial infarctions and stroke events. Sensitivity analysis affirmed the robustness of these results for patients aged under 70 years., Conclusions: The SGLT2 inhibitor treatment appeared to be cost-effective for the overall population of our study and particularly for younger patients (<70 years old). For older patients (≥70 years old), the cost-effectiveness was less clear and may require further evaluation. Decision-makers should consider this age-based heterogeneity when making recommendations about SGLT2 inhibitor treatment., (© 2024 The Author(s).

Background: Coronary artery angiography (CAG) and percutaneous coronary intervention (PCI) are superior to non-invasive approaches in reducing mortality in patients with ST-segment elevation myocardial infarction (STEMI). However, their efficacy remains uncertain in non-ST-elevation acute coronary syndromes (NSTE-ACS) and limited in low-resource settings. This study aimed to compare in-hospital and 5-year mortality rates between patients with a first event of STEMI and NSTE-ACS who underwent CAG and PCI and those with similar severity who did not undergo CAG and PCI., Methods: A propensity-matched retrospective cohort study was conducted using population-based claims data of national universal coverage of Thailand for identification of patients with acute coronary syndromes. The mortality of recruited patients was additionally linked to the national database of vital registration. Patients aged ≥ 40 years who were hospitalized for STEMI and NSTE-ACS in 2017, with a focus on access to CAG and PCI were included. For each condition either STEMI or NSTE-ACS, patients who underwent CAG and PCI were matched to those who did not undergo using propensity score matching (PSM) to balance measured confounders, such as age, sex, and underlying conditions. In-hospital mortality rate ratio and 5-year mortality were analyzed as measures., Results: Through PSM, 2,702 non-intervention STEMI patients were paired with an equal number of intervention patients, and similarly, 5,072 non-intervention NSTE-ACS patients were matched with an equivalent group who received interventions. For patients with STEMI, the in-hospital mortality rate ratio (95% confidence interval (CI)) for those who underwent CAG and PCI compared to those who did not was 30.1% (30.0%, 30.2%). Similar trends were observed in patients with NSTE-ACS with a mortality rate of 34.7% (34.6%, 34.8%). For the five-year mortality comparison, the hazard ratios (95% CI) of mortality after discharge were 0.55 (0.50, 0.62) for STEMI and 0.57 (0.54, 0.61) for NSTE-ACS cases., Conclusions: Access to CAG and PCI was significantly associated with lower in-hospital and 5-year mortality rates in patients who experienced their first event of ACS, despite the limited availability of some unmeasured or residual confounders. Healthcare systems should expand their resources for CAG and PCI in Thailand and other countries to equitably enhance longevity., Competing Interests: Declarations Ethics approval and consent to participate Patient data were encrypted and deidentified for personalized anonymization, according to the Thai Personal Data Protection Act 2019, Thailand.

Background: It has been suggested that the association between body mass index and breast cancer risk differs between Asian women and Western women. We aimed to assess the associations between body mass index and breast cancer incidence in East Asian women., Methods: Pooled analyses were performed using individual participant data of 319,189 women from 13 cohort studies in Japan, Korea, and China. Participants' height and weight were obtained by measurement or self-reports at cohort baseline. Breast cancer was defined as code C50.0-C50.9 according to the International Classification. Using a Cox proportional hazards model, hazard ratios of breast cancer were estimated for each body mass index category, with the reference group set as the group with a body mass index of 21 to < 23 kg/m 2 . The hazard ratio for a 5 kg/m 2 increase in body mass index was also calculated., Results: During a mean 16.6 years of follow-up, 4819 women developed breast cancer. Similar to Westerners, a steady increase in breast cancer risk with increasing body mass index was observed in postmenopausal women, but the slope of the risk increase appeared to slow at a body mass index of 26-28 kg/m 2 . In premenopausal women, the inverse association seen in Westerners was not observed. The risk of developing breast cancer after 50 years of age increased slightly with increasing body mass index, which was more pronounced in the older birth cohort. There was no significant association between body mass index and the risk of developing breast cancer before 50 years of age, but the risk estimates changed from positive to negative as the birth cohort got younger., Conclusions: In East Asia, the role of body mass index in breast cancer in premenopausal women may be changing along with the increase in obesity and breast cancer. The increased risk of postmenopausal breast cancer with a higher body mass index was as robust as that of Western women., Competing Interests: Declarations Ethics approval and consent to participate This study was performed in accordance with the Declaration of Helsinki. Each participating study was approved by the relevant institutional ethical review boards. The protocol for the ACC analysis was approved by the institutional review board of the National Cancer Center, Japan.

Background: Rituximab is widely used in patients with steroid-dependent nephrotic syndrome. However, information on the effect of long-term rituximab treatment is limited. This study examined the efficacy of rituximab during and after treatment in adult patients with steroid-dependent nephrotic syndrome., Methods: This retrospective cohort study included 30 patients with steroid-dependent nephrotic syndrome. Patients received regular single-dose rituximab (500 mg) intravenously every 6 months. Discontinuation of rituximab was considered after four to six doses if there was no recurrence of nephrotic syndrome. Glucocorticoid discontinuation with remission, first relapse after rituximab initiation, and relapse after regular rituximab treatment discontinuation were evaluated., Results: The median age was 38 (range 18-67) years. Of 30 patients, 13 and 17 were men and women, respectively. Prior to rituximab treatment, the median number of nephrotic syndrome relapses in the patients was 5 (range 2- > 20). The 1 year discontinuation rate of glucocorticoids with remission was 83%. All patients discontinued glucocorticoid treatment at least once until 3 years and 7 months. The 1 and 2 year relapse rates after initiation of rituximab treatment were 0% and 3%, respectively. 25 patients discontinued regular rituximab treatment after a median number of six (4-12) doses. Six patients relapsed after discontinuing rituximab, and the 1 and 2 year relapse rates after the last regular rituximab treatment were 9% and 25%, respectively., Conclusion: All patients with steroid-dependent nephrotic syndrome who received rituximab could discontinue glucocorticoid treatment with remission, and three-fourths of the patients remained in remission for > 2 years after discontinuing rituximab treatment., Competing Interests: Declarations Conflict of interest The authors have declared that no conflict of interest exists. Ethical approval This study was approved by the Ethics Committee of Iwate Prefectural Central Hospital and conducted in accordance with the ethical principles of the Declaration of Helsinki. Informed consent A written informed consent was not obtained from the patients because the ethical guidelines for epidemiological research in Japan do not require informed consent for a retrospective cohort study using only existing medical records., (© 2024.

We developed the "Itappachi" universal motion platform for measuring radiation doses under simulated respiratory motion in radiation therapy. The interplay effect, resulting from respiratory motion, degrades dose delivery precision in advanced treatments such as volumetric modulated arc therapy. The Itappachi platform is designed for precise dose measurement in dynamic scenarios through its ability to simulate respiratory motion. The platform features a large surface (580 mm × 380 mm), capable of supporting weights up to 56.8 kg, and moves with an amplitude of ±25 mm. It requires no silicone oil for maintenance, and it is controlled via Wi-Fi using user-owned devices, thereby reducing costs. Its motion accuracy was confirmed, with a maximum displacement error of 0.12 mm. Using the platform, we conducted dose measurements with a Delta4 Phantom under static, moving without gated irradiation, and moving with gated irradiation conditions. Gamma index analysis revealed excellent agreement for static and dynamic gated conditions (99.4%), while significant dose degradation occurred in the non-gated dynamic condition (32.6%). The Itappachi platform provides a cost-effective and accurate solution for dose measurement under respiratory motion by which it supports improved quality assurance in radiation therapy., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Objective: To evaluate the conditional effect of time spent in the kitchen on the association between frailty status and healthy diet among older women., Design: Secondary analysis of an online cross-sectional survey conducted in January 2023., Participants: Six hundred Japanese women (aged ≥ 65 years)., Main Outcome Measure(s): Frailty status evaluated using the Kihon Checklist (25 affirmative questions assessing daily functions, weight status, and mental condition); healthy diet assessed by the days of consuming ≥ 2 meals that include staple, main and side dishes in a meal (SMS meal) in a day; and time spent in the kitchen., Analysis: Moderation analysis was used to evaluate the conditional effect of time spent in the kitchen on frailty status and SMS meal intake. Chi-square tests for independence were used to evaluate the differences in the Kihon Checklist items by frailty status., Results: Spending longer time in the kitchen indicated more frequent SMS meal intake and the trend was stronger among older women with frailty than those with robustness. All items except for 1 item regarding weight status (P = 0.15) were significantly associated with frailty status (P < 0.001)., Conclusions and Implications: Further studies are needed to evaluate the causal relationship between frailty status, healthy diet, and kitchen use., (Copyright © 2024 The Authors.

There has been growing evidence suggesting that diabetes may be associated with increased liver cancer risk. However, studies conducted in Asian countries are limited. This project considered data of 968,738 adults pooled from 20 cohort studies of Asia Cohort Consortium to examine the association between baseline diabetes and liver cancer incidence and mortality. Cox proportional hazard model and competing risk approach was used for pooled data. Two-stage meta-analysis across studies was also done. There were 839,194 subjects with valid data regarding liver cancer incidence (5654 liver cancer cases [48.29/100,000 person-years]), follow-up time and baseline diabetes (44,781 with diabetes [5.3%]). There were 747,198 subjects with valid data regarding liver cancer mortality (5020 liver cancer deaths [44.03/100,000 person-years]), follow-up time and baseline diabetes (43,243 with diabetes [5.8%]). Hazard ratio (HR) (95% confidence interval [95%CI]) of liver cancer diagnosis in those with vs. without baseline diabetes was 1.97 (1.79, 2.16) (p < .0001) after adjusting for baseline age, gender, body mass index, tobacco smoking, alcohol use, and heterogeneity across studies (n = 586,072; events = 4620). Baseline diabetes was associated with increased cumulative incidence of death due to liver cancer (adjusted HR (95%CI) = 1.97 (1.79, 2.18); p < .0001) (n = 595,193; events = 4110). A two-stage meta-analytic approach showed similar results. This paper adds important population-based evidence to current literature regarding the increased incidence and mortality of liver cancer in adults with diabetes. The analysis of data pooled from 20 studies of different Asian countries and the meta-analysis across studies with large number of subjects makes the results robust., (© 2024 UICC.)

Importance: The global burden of obesity is increasing, as are colorectal cancer (CRC) incidence and mortality., Objectives: To assess the association between body mass index (BMI) and risks of incident CRC and CRC-related death in the Asian population., Design, Setting, and Participants: This cohort study includes data pooled from 17 prospective cohort studies included in The Asia Cohort Consortium. Cohort enrollment was conducted from January 1, 1984, to December 31, 2002. Median follow-up time was 15.2 years (IQR, 12.1-19.2 years). Data were analyzed from January 15, 2023, through January 15, 2024., Exposure: Body mass index, calculated as weight in kilograms divided by height in meters squared., Main Outcomes and Measures: The primary outcomes were CRC incidence and CRC-related mortality. The risk of events is reported as adjusted hazard ratios (AHRs) and 95% CIs for incident CRC and death from CRC using the Cox proportional hazards regression model., Results: To assess the risk of incident CRC, 619 981 participants (mean [SD] age, 53.8 [10.1] years; 52.0% female; 11 900 diagnosed incident CRC cases) were included in the study, and to assess CRC-related mortality, 650 195 participants (mean [SD] age, 53.5 [10.2] years; 51.9% female; 4550 identified CRC deaths) were included in the study. A positive association between BMI and risk of CRC was observed among participants with a BMI greater than 25.0 to 27.5 (AHR, 1.09 [95% CI, 1.03-1.16]), greater than 27.5 to 30.0 (AHR, 1.19 [95% CI, 1.11-1.29]), and greater than 30.0 (AHR, 1.32 [95% CI, 1.19-1.46]) compared with those with a BMI greater than 23.0 to 25.0 (P < .001 for trend), and BMI was associated with a greater increase in risk for colon cancer than for rectal cancer. A similar association between BMI and CRC-related death risk was observed among participants with a BMI greater than 27.5 (BMI >27.5-30.0: AHR, 1.18 [95% CI, 1.04-1.34]; BMI >30.0: AHR, 1.38 [95% CI, 1.18-1.62]; P < .001 for trend) and was present among men with a BMI greater than 30.0 (AHR, 1.87 [95% CI, 1.49-2.34]; P < .001 for trend) but not among women (P = .15 for trend) (P = .02 for heterogeneity)., Conclusions and Relevance: In this cohort study that included a pooled analysis of 17 cohort studies comprising participants across Asia, a positive association between BMI and CRC incidence and related mortality was found. The risk was greater among men and participants with colon cancer. These findings may have implications to better understand the burden of obesity on CRC incidence and related deaths in the Asian population.

Objective: During the COVID-19 pandemic, the prevalence of depression and anxiety among children and adolescents significantly increased, along with the number of visits to emergency departments due to suicidality and/or suicide attempts. Relatedly, health care workers experienced significant burnout and symptoms of anxiety, depression, and posttraumatic stress disorder during this time. However, the corresponding impact on psychiatric inpatient treatment has not yet been researched. We hypothesized that during the pandemic, adolescents hospitalized in an acute care psychiatric inpatient unit had increased incidents of suicide attempts and nonsuicidal self-injurious behaviors and of aggressive behaviors toward others, resulting in greater use of constant observation and restraints. Method: This study was a retrospective chart review based on electronic medical record data examining use of restraints and constant observation one year before the pandemic (March 2019 to February 2020) and 1 year following the onset of the pandemic (March 2020 to February 2021) in an acute-care adolescent (12 to 17 years old) psychiatric inpatient unit. Results: There were 571 admissions during the year before the pandemic and 500 admissions during the pandemic. The number of patients who were restrained ( χ 2 = 7.86, p = 0.005), number of patients who were placed on constant observation ( χ 2 = 13.41, p < 0.001 ), and number of constant observation orders per patient ( χ 2 = 91.90, p < 0.001 ) were all significantly greater during the pandemic. Conclusion: Psychiatrically hospitalized adolescents during the pandemic received more intensive interventions such as restraints and constant observation. Severe patient psychopathology and staff shortages, as well as limitations of and decreases to the dialectical behavior therapy program, may have been the contributing factor.

Background: Demographic changes and a low birth rate have led to a workforce shortage in Japan. To address this issue, the government has promoted engagement of female employment. However, increased female employment can impact women's health. Using Internet of Things (IoT) and apps to manage women's health has gained attention, but few studies have focused on working women., Objective: This study aimed to clarify the current situation of working women and their use of IoT or apps to manage their health., Methods: A large-scale, nationwide internet survey was conducted among 10,000 female participants aged from 20 years to 64 years in Japan. Participants were recruited from a marketing research company's active survey panel of 5.24 million members. The survey included questions about health status, sociodemographic factors, psychological characteristics, and the use of IoT or apps for health management. We compared perceived health status and reasons for current IoT use using t tests and assessed participant characteristics that predicted IoT use using the C5.0 decision tree algorithm. Ethical approval was granted by St. Luke's International University., Results: Among participants, 14.6% (1455/10,000) currently used IoT or apps, 7% (695/10,000) used them previously, and 78.5% (7850/10,000) had never used them. Current users (42.7 years old) were older than past users (39.7 years old). Discrepancies were observed between participants' perceived health problems and the purpose for using IoT or apps, with 21.3% (2130/10,000) of all women reporting they experienced menstrual symptoms or disorders but only 3.5% (347/10,000) used IoT or apps to manage the same symptom. On the other hand, current users were more likely to use IoT or apps to manage nutrition-related problems such as underweight or obesity (405/1455, 27.8%). Device use was highest among current users, with 87.3% (1270/1455) using smartphones, 19.7% (287/1455) using smartwatches, and 13.3% (194/1455) using PCs. Decision tree analysis identified 6 clusters, the largest consisting of 81.6% (5323/6523) of non-IoT users who did not exercise regularly, while pregnant women were more likely to use IoT or apps., Conclusions: Our findings highlight the idea that woman with particular health problems (ie, menstrual symptoms or disorders and premenstrual syndrome) have lower use of IoT or apps, suggesting an unmet need for IoT and apps in specific areas., (©Kirio Sasayama, Etsuko Nishimura, Noyuri Yamaji, Erika Ota, Hisateru Tachimori, Ataru Igarashi, Naoko Arata, Daisuke Yoneoka, Eiko Saito.

The female predominance of gallbladder cancer (GBC) has led to a hypothesis regarding the hormone-related aetiology of GBC. We aimed to investigate the association between female reproductive factors and GBC risk, considering birth cohorts of Asian women. We conducted a pooled analysis of 331,323 women from 12 cohorts across 4 countries (China, Japan, Korea, and Singapore) in the Asia Cohort Consortium. Cox proportional hazard models were used to estimate the hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) to assess the association between reproductive factors (age at menarche, parity, age at first delivery, breastfeeding, and age at menopause) and GBC risk. We observed that a later age at menarche was associated with an increased risk of GBC (HR 1.4, 95% CI 1.16-1.70 for 17 years and older vs. 13-14 years), especially among the cohort born in 1940 and later (HR 2.5, 95% CI 1.50-4.35). Among the cohort born before 1940, women with a later age at first delivery showed an increased risk of GBC (HR 1.56, 95% CI 1.08-2.24 for 31 years of age and older vs. 20 years of age and younger). Other reproductive factors did not show a clear association with GBC risk. Later ages at menarche and at first delivery were associated with a higher risk of GBC, and these associations varied by birth cohort., (© 2024 The Authors.

Heparin-induced thrombocytopenia (HIT) is an immune-mediated disease with severe thromboembolic complications. HIT during percutaneous coronary intervention (PCI) can be fatal without prompt treatment. We report an unusual case of HIT observed during PCI for acute coronary syndrome (ACS). A 74-year-old female with a history of pulmonary embolism managed with unfractionated heparin (UFH) 2 years previously presented with intermittent chest pain. Coronary angiography revealed total occlusion of the mid-right coronary artery. Before and during the primary PCI, 14000 UFH units were administered. However, abundant thrombus formation in the non-culprit lesion was refractory to repeated thrombus aspiration. We suspected HIT, discontinued UFH, and administered argatroban. Despite repeated thrombus aspirations and balloon dilatation, coronary obstruction persisted; consequently, ventricular fibrillation refractory to multiple cardioversions occurred. Therefore, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) was required. Platelet counts rapidly decreased to <50 % of the baseline value, and serum was highly positive for IgG-specific antiplatelet factor 4/heparin antibodies. The patient was discharged with independent gait and no major neurological disorders. This is a clinically noteworthy case of rapidly developing HIT during primary PCI for ACS, requiring VA-ECMO management, with no major neurological complications. HIT may occur immediately after re-exposure to heparin long after the first exposure., Learning Objective: Without prompt treatment, heparin-induced thrombocytopenia (HIT) during percutaneous coronary intervention (PCI) can be fatal. It may lead to refractory coronary obstruction, which may need to be managed by veno-arterial extracorporeal membrane oxygenation (VA-ECMO).

Background: The family history of gastric cancer holds important implications for cancer surveillance and prevention, yet existing evidence predominantly comes from case-control studies. We aimed to investigate the association between family history of gastric cancer and gastric cancer risk overall and by various subtypes in Asians in a prospective study., Methods: We included 12 prospective cohorts with 550,508 participants in the Asia Cohort Consortium. Cox proportional hazard regression was used to estimate study-specific adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between family history of gastric cancer and gastric cancer incidence and mortality, then pooled using random-effects meta-analyses. Stratified analyses were performed for the anatomical subsites and histological subtypes., Results: During the mean follow-up of 15.6 years, 2258 incident gastric cancers and 5194 gastric cancer deaths occurred. The risk of incident gastric cancer was higher in individuals with a family history of gastric cancer (HR 1.44, 95% CI 1.32-1.58), similarly in males (1.44, 1.31-1.59) and females (1.45, 1.23-1.70). Family history of gastric cancer was associated with both cardia (HR 1.26, 95% CI 1.00-1.60) and non-cardia subsites (1.49, 1.35-1.65), and with intestinal- (1.48, 1.30-1.70) and diffuse-type (1.59, 1.35-1.87) gastric cancer incidence. Positive associations were also found for gastric cancer mortality (HR 1.30, 95% CI 1.19-1.41)., Conclusions: In this largest prospective study to date on family history and gastric cancer, a familial background of gastric cancer increased the risk of gastric cancer in the Asian population. Targeted education, screening, and intervention in these high-risk groups may reduce the burden of gastric cancer., (© 2024. The Author(s).)

Background/aims: The efficacy and safety of tofacitinib for the treatment of refractory ulcerative colitis (UC) has been demonstrated in clinical trials. Although, a series of reports with real-world evidence of its short-term efficacy and safety profiles have already been published, reports of long-term real-world data have been limited. We aimed to show our 3-year evidence on the clinical use of tofacitinib for the treatment of UC, focusing on its efficacy and safety profiles., Methods: A retrospective observational study was conducted on patients who started tofacitinib for active refractory UC at our hospital. The primary outcome was the retention rate until 156 weeks after initiating tofacitinib. The secondary outcomes were short-term efficacy at 4, 8, and 12 weeks; long-term efficacy at 52, 104, and 156 weeks; prognostic factors related to the cumulative retention rate; loss of response; and safety profile, including adverse events., Results: Forty-six patients who were able to be monitored for up to 156 weeks after tofacitinib initiation, were enrolled in this study. Continuation of tofacitinib was possible until 156 weeks in 54.3%, with > 50% response rates and > 40% remission rates. Among patients in whom response or remission was achieved and tofacitinib was deescalated after 8 weeks of induction treatment, 54.3% experienced relapse but were successfully rescued by and retained on reinduction treatment, except for 1 patient. No serious AEs were observed in the study., Conclusions: Tofacitinib is effective and safe as long-term treatment in a refractory cohort of UC patients in real-world clinical practice.

Previous studies have investigated the association between reproductive factors and lung cancer risk; however, findings have been inconsistent. In order to assess this association among Asian women, a total of 308,949 female participants from 11 prospective cohorts and four Asian countries (Japan, Korea, China, and Singapore) were included. Cox proportional hazards regression models were used to estimate the hazard ratios (HR) and 95% confidence intervals (CIs). A total of 3,119 primary lung cancer cases and 2247 lung cancer deaths were identified with a mean follow-up of 16.4 years. Parous women had a lower risk of lung cancer incidence and mortality as compared with nulliparous women, with HRs of 0.82 (95% CI = 0.70-0.96) and 0.78 (95% CI = 0.65-0.94). The protective association of parity and lung cancer incidence was greater among ever-smokers (HR = 0.66, 95% CI = 0.49-0.87) than in never-smokers (HR = 0.90, 95% CI = 0.74-1.09) (P-interaction = 0.029). Compared with age at first delivery ≤20 years, older age at first delivery (21-25, ≥26 years) was associated with a lower risk of lung cancer incidence and mortality. Women who ever used hormone replacements had a higher likelihood of developing non-small cell lung cancer (HR = 1.31, 95% CI = 1.02-1.68), compared to those who never used hormone replacements. Future studies are needed to assess the underlying mechanisms, the relationships within these female reproductive factors, and the potential changes in smoking habits over time., (© 2024 UICC.)

We present the validity of using an ultrasensitive enzyme-linked immunosorbent assay (ELISA) for quantifying high-risk human papillomavirus (HPV) 16 E7 oncoproteins in urine specimens as a noninvasive method of analyzing the oncogenic activity of HPV. Some reports claim that the oncogenic activity of HPV is a more relevant clinical indicator than the presence of HPV DNA for estimating malignant potential. In the present study, urine containing HPV16 and related types were selected by uniplex E6/E7 polymerase chain reaction and classified according to the pathologic diagnosis of cervical intraepithelial neoplasia (CIN) in cervical biopsy specimens. Our ultrasensitive ELISA was able to detect attomole levels of HPV16 E7 oncoproteins, and it detected HPV16-positive SiHa cells at >500 cells/mL without detecting HPV18-positive cells. Our ELISA results showed E7 oncoproteins in 80% (4/5) of urine specimens from women with HPV16-positive CIN1, 71% (5/7) of urine specimens from CIN2 patients, and 38% (3/8) of urine specimens from CIN3 patients. Some urine specimens with undetectable E7 oncoproteins were thought to be negative for live HPV 16-positive cells or in an inactivated state of infection. These results provide the basis for assessing oncogenic activity by quantifying E7 oncoproteins in patient urine.

Background: Evidence suggests a possible link between diabetes and gastric cancer risk, but the findings remain inconclusive, with limited studies in the Asian population. We aimed to assess the impact of diabetes and diabetes duration on the development of gastric cancer overall, by anatomical and histological subtypes., Methods: A pooled analysis was conducted using 12 prospective studies included in the Asia Cohort Consortium. Among 558 981 participants (median age 52), after a median follow-up of 14.9 years and 10.5 years, 8556 incident primary gastric cancers and 8058 gastric cancer deaths occurred, respectively. Cox proportional hazard regression models were used to estimate study-specific hazard ratios (HRs) and 95% confidence intervals (CIs) and pooled using random-effects meta-analyses., Results: Diabetes was associated with an increased incidence of overall gastric cancer (HR 1.15, 95% CI 1.06-1.25). The risk association did not differ significantly by sex (women vs men: HR 1.31, 95% CI 1.07-1.60 vs 1.12, 1.01-1.23), anatomical subsites (noncardia vs cardia: 1.14, 1.02-1.28 vs 1.17, 0.77-1.78) and histological subtypes (intestinal vs diffuse: 1.22, 1.02-1.46 vs 1.00, 0.62-1.61). Gastric cancer risk increased significantly during the first decade following diabetes diagnosis (HR 4.70, 95% CI 3.77-5.86), and decreased with time (nonlinear p < .01). Positive associations between diabetes and gastric cancer mortality were observed (HR 1.15, 95% CI 1.03-1.28) but attenuated after a 2-year time lag., Conclusion: Diabetes was associated with an increased gastric cancer incidence regardless of sex, anatomical subsite, or subtypes of gastric cancer. The risk of gastric cancer was particularly high during the first decade following diabetes diagnosis., (© 2024 The Authors.

This study investigated the diagnostic and surgical management of urachal abscessation involving the urinary bladder in three cattle aged >18 months. While the abdominal floor or paralumbar fossa are typically considered for accessing the urachus and bladder in calves and heifers, the distance is too great to perform the procedure under direct vision in adult cows. Therefore, a novel preinguinal approach was used for access in cows with urachal abscesses after 18 months. Access was successfully achieved in all the three cows through a preinguinal incision to the urachal abscess at the apex of the bladder. However, in cases wherein the abscess and adhesions are severe, removal may be challenging or may necessitate a combined median or paramedian approach.

Piceatannol (PIC), a polyphenol abundant in passion fruit seeds, is reported to promote fat metabolism. This study investigated whether PIC affects sirtuin 1 (SIRT1) expression and metabolic factors in C2C12 skeletal muscle cells. C2C12 myotubes were stimulated with PIC, and alterations in gene expression, protein levels, mitochondrial DNA content, and fatty acid levels were assessed using real-time PCR, Western blotting, and Nile red staining. Furthermore, we examined changes in SIRT1 expression following the consumption of a test food containing 100 mg PIC for 2 weeks among adults with varying age and body mass index ranges. Both PIC and passion fruit seed extract induced SIRT1 expression in C2C12 myotubes to a greater extent than resveratrol. PIC also increased the expression of genes associated with mitochondrial biogenesis and fatty acid utilization, increased mitochondrial DNA content, and suppressed oleic acid-induced fat accumulation. Moreover, participants who consumed PIC exhibited significantly higher SIRT1 mRNA expression in whole blood compared to those in the placebo group. These findings suggest that PIC induces SIRT1 expression both in vitro and in the human body, which may promote mitochondrial biosynthesis and fat metabolism.

Purpose　Since 2020, UHC2030 has undertaken a project to review the progress of UN member states in fulfilling their commitments toward achieving universal health coverage (UHC) as outlined in the 2019 UHC Political Declaration. This involves identifying countries where UHC progress is of particular concern and engaging with multi-stakeholders. This article aims to provide a concise overview and widespread introduction to the State of UHC Commitment project for public health experts in Japan, with particular emphasis on the key findings from a pilot project on voluntary national reviews.Method　In order to gauge the evidence-based accountability actions of governments toward UHC, we conducted a comprehensive review of initial five-year Voluntary National Review (VNR) reports (2016-2020, 187 reports) published at the United Nations High-level Political Forum (HLPF). This included all descriptions (quantitative and qualitative information) regarding UHC and health systems. We also compared the descriptions in the latest VNR reports (40 reports) available as of February 2021. We checked whether there have been any improvements in the evidence-based accountability of each country.Research Results　We compared the 2021 VNR reports and the first five-year VNR reports and observed an improvement in evidence-based accountability. However, considering the wealth of data released by the United Nations Statistics on UHC and health systems, these indicators have not yet been fully utilized for accountability purposes.Conclusion　Despite the UHC Political Declaration follow-up meeting and the SDGs Mid-term Review held at the United Nations General Assembly in September 2023, some UHC targets set in 2019 have been postponed to 2025. The current status of UHC progress poses challenges to achieving the 2030 goal. There is an urgent need to strengthen governments' evidence-based accountability using UN statistics and promote UHC progress by implementing the agreed Political Declaration.

Objective: Patients' race and age have each been identified as risk factors for experiencing restraint events during psychiatric hospitalization. Restraint duration is also an important variable in determining disparities in treatment. To the authors' knowledge, no studies to date have examined the effect of the interaction of race and age on restraint use and duration in inpatient psychiatric settings. This retrospective chart review of electronic medical records of patients admitted between 2012 and 2019 sought to examine whether race and age interacted in predicting differences in the use and duration of restraints in a psychiatric inpatient setting., Methods: Logistic and hierarchical regression analyses were conducted on data from a sample of 29,739 adolescent (ages 12-17 years) and adult (ages ≥18 years) inpatients to determine whether the interaction of race and age group (adolescent or adult) significantly predicted a restraint event or differences in restraint duration., Results: Black (adjusted OR [AOR]=1.85) and multiracial (AOR=1.36) patients were more likely to experience a restraint event than were their White peers. Black race was also significantly (p=0.001) associated with longer restraint duration. No significant interaction was detected between race and age in predicting restraint events or duration., Conclusions: Although the interaction between race and age did not predict restraint events or duration, the findings indicate racial disparities in the frequency and duration of restraint events among Black and multiracial individuals and may inform efforts to reduce these events., Competing Interests: Dr. Hanna reports owning stocks in Doximity.

Body fatness is considered a probable risk factor for biliary tract cancer (BTC), whereas cholelithiasis is an established factor. Nevertheless, although obesity is an established risk factor for cholelithiasis, previous studies of the association of body mass index (BMI) and BTC did not take the effect of cholelithiasis fully into account. To better understand the effect of BMI on BTC, we conducted a pooled analysis using population-based cohort studies in Asians. In total, 905 530 subjects from 21 cohort studies participating in the Asia Cohort Consortium were included. BMI was categorized into four groups: underweight (<18.5 kg/m 2 ); normal (18.5-22.9 kg/m 2 ); overweight (23-24.9 kg/m 2 ); and obese (25+ kg/m 2 ). The association between BMI and BTC incidence and mortality was assessed using hazard ratios (HR) and 95% confidence intervals (CIs) by Cox regression models with shared frailty. Mediation analysis was used to decompose the association into a direct and an indirect (mediated) effect. Compared to normal BMI, high BMI was associated with BTC mortality (HR 1.19 [CI 1.02-1.38] for males, HR 1.30 [1.14-1.49] for females). Cholelithiasis had significant interaction with BMI on BTC risk. BMI was associated with BTC risk directly and through cholelithiasis in females, whereas the association was unclear in males. When cholelithiasis was present, BMI was not associated with BTC death in either males or females. BMI was associated with BTC death among females without cholelithiasis. This study suggests BMI is associated with BTC mortality in Asians. Cholelithiasis appears to contribute to the association; and moreover, obesity appears to increase BTC risk without cholelithiasis., (© 2023 UICC.)

Background: Resistant bacterial infections, particularly those caused by gram-negative pathogens, are associated with high mortality and economic burdens. Ceftolozane/tazobactam demonstrated efficacy comparable to meropenem in patients with ventilated hospital-acquired bacterial pneumonia in the ASPECT-NP study. One cost-effectiveness analysis in the United States revealed that ceftolozane/tazobactam was cost effective, but no Japanese studies have been conducted. Therefore, the objective of this study was to assess the cost-effectiveness of ceftolozane/tazobactam compared to meropenem for patients with ventilated hospital-acquired bacterial pneumonia/ventilator-associated bacterial pneumonia from a health care payer perspective., Methods: A hybrid decision-tree Markov decision-analytic model with a 5-year time horizon were developed to estimate costs and quality-adjusted life-years and to calculate the incremental cost-effectiveness ratio associated with ceftolozane/tazobactam and meropenem in the treatment of patients with ventilated hospital-acquired bacterial pneumonia/ventilator-associated bacterial pneumonia. Clinical outcomes were based on the ASPECT-NP study, costs were based on the national fee schedule of 2022, and utilities were based on published data. One-way sensitivity analysis and probabilistic sensitivity analysis were also conducted to assess the robustness of our modeled estimates., Results: According to our base-case analysis, compared with meropenem, ceftolozane/tazobactam increased the total costs by 424,731.22 yen (£2,626.96) and increased the quality-adjusted life-years by 0.17, resulting in an incremental cost-effectiveness ratio of 2,548,738 yen (£15,763.94) per quality-adjusted life-year gained for ceftolozane/tazobactam compared with meropenem. One-way sensitivity analysis showed that although the incremental cost-effectiveness ratio remained below 5,000,000 yen (£30,925) for most of the parameters, the incremental net monetary benefit may have been less than 0 depending on the treatment efficacy outcome, especially the cure rate and mortality rate for MEPM and mortality rate for CTZ/TAZ. 53.4% of the PSA simulations demonstrated that CTZ/TAZ was more cost-effective than MEPM was., Conclusion: Although incremental cost-effectiveness ratio was below ￥5,000,000 in base-case analysis, whether ceftolozane/tazobactam is a cost-effective alternative to meropenem for ventilated hospital-acquired bacterial pneumonia/ventilator-associated bacterial pneumonia in Japan remains uncertain. Future research should examine the unobserved heterogeneity across patient subgroups and decision-making settings, to characterise decision uncertainty and its consequences so as to assess whether additional research is required., (© 2024.

Introduction: Although lung cancer prediction models are widely used to support risk-based screening, their performance outside Western populations remains uncertain. This study aims to evaluate the performance of 11 existing risk prediction models in multiple Asian populations and to refit prediction models for Asians., Methods: In a pooled analysis of 186,458 Asian ever-smokers from 19 prospective cohorts, we assessed calibration (expected-to-observed ratio) and discrimination (area under the receiver operating characteristic curve [AUC]) for each model. In addition, we developed the "Shanghai models" to better refine risk models for Asians on the basis of two well-characterized population-based prospective cohorts and externally validated them in other Asian cohorts., Results: Among the 11 models, the Lung Cancer Death Risk Assessment Tool yielded the highest AUC (AUC [95% confidence interval (CI)] = 0.71 [0.67-0.74] for lung cancer death and 0.69 [0.67-0.72] for lung cancer incidence) and the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial Model had good calibration overall (expected-to-observed ratio [95% CI] = 1.06 [0.90-1.25]). Nevertheless, these models substantially underestimated lung cancer risk among Asians who reported less than 10 smoking pack-years or stopped smoking more than or equal to 20 years ago. The Shanghai models were found to have marginal improvement overall in discrimination (AUC [95% CI] = 0.72 [0.69-0.74] for lung cancer death and 0.70 [0.67-0.72] for lung cancer incidence) but consistently outperformed the selected Western models among low-intensity smokers and long-term quitters., Conclusions: The Shanghai models had comparable performance overall to the best existing models, but they improved much in predicting the lung cancer risk of low-intensity smokers and long-term quitters in Asia., (Copyright © 2023.

Background: The Japanese 2020 cervical screening guidelines recommend conventional cervical cytology screening every 2-years for women aged 20-69 years. The nonavalent human papillomavirus (HPV) vaccine has also recently been approved in Japan. We therefore evaluated the cost-effectiveness of cervical cancer screening strategies alongside universal nonavalent HPV vaccination of girls (12-16 years)., Methods: A cost-effectiveness analysis was performed using an age-specific Markov microsimulation model for Japan to evaluate total costs, quality adjusted life-years (QALYs) gained, incremental cost-effectiveness ratios (ICER), colposcopies, biopsies, precancer and cervical cancer treatments for 29 combined vaccination and screening strategies (conventional cytology, liquid-based cytology (LBC), HPV testing, and HPV self-collection). A cohort of 100,000 girls (12-16 years old) over a lifetime offered the nonavalent HPV vaccine was used (current vaccination coverage = 0.08%, current screening coverage = 43.7%). A discount rate of 3% was applied to costs and QALYs. Univariate and probabilistic sensitivity analysis was performed to assess robustness of the findings. Costs were reported in US dollars (2023)., Findings: Compared with conventional cytology, evaluated strategies would incur an additional cost of US$839,280-738,182,669 and gain 62,755-247,347 quality-adjusted-life-years. HPV testing distinguishing HPV16/18 with reflex LBC (3-yearly) would be most cost-effective (ICER = US$7511 per QALY gained). At a willingness-to-pay (WTP) of 1-times gross domestic product (GDP) per capita, the probability of it being cost-effective was 70%. At historically high vaccination coverage (70%) ICERs decreased overall but did not affect the ranking of the most cost-effective strategy. While a 5-yearly interval became more cost-effective than a 3-yearly interval. Including HPV self-collection for under-screened women made all strategies more cost-effective., Interpretation: At current cervical screening participation (43.7%) and low vaccination coverage (<1.0%), HPV testing distinguishing HPV16/18 with reflex LBC (3-yearly) would be the most cost-effective screening strategy compared to conventional cytology (2-yearly)., Funding: Grants-in-Aid for Scientific Research from the Japan Society for the Promotion of Science (17H03589) and Grants of the National Cancer Center Japan (Gan Kenkyu Kaihatsuhi 31-A-20 and 2023-A-23)., Competing Interests: KK received payment from the Japan Society for the Promotion of Science and National Cancer Center Japan.

Background: Tertiary lymphoid structures (TLSs) are observed in cancer-invasive sites of various organs, and show evidence of tumor-specific B and/or T cells, suggesting an active humoral antitumor response. The aim of this study was to evaluate the relationship between TLSs and prognosis in patients with tongue squamous cell carcinoma (TSCC) after preoperative S-1 chemotherapy., Methods: Among 196 TSCC cases, 111 patients who received preoperative S-1 chemotherapy were compared to 85 patients who did not receive chemotherapy. We investigated the incidence of TLSs in both preoperative biopsy and resected specimens., Results: TLSs were present in 24 (12%) biopsy specimens and 31 (16%) resected specimens. TLSs were associated with clinicopathologically advanced cases and positivity for lymphatic invasion. None of the cases with pStage 0 (i.e., noninvasive cancer) showed TLSs. In preoperative S-1 chemotherapy cases, TLSs were significantly more common in those treated with S-1 for more than 21 days and in those with treatment effects 0, Ia, and Ib. TLSs may not be a favorable prognostic factor by themselves but maybe a prognostic factor when combined with preoperative S-1 treatment., Conclusion: The presence of TLSs was suggested to be a factor indicating a favorable prognosis when considering the indication for preoperative S-1 chemotherapy. The synergistic effect of S-1 by activating antitumor immunity may be associated with a better prognosis in TSCC patients with TLSs., (© 2024 John Wiley & Sons A/S.

Background: The birth cohort effect has been suggested to influence the rate of breast cancer incidence and the trends of associated reproductive and lifestyle factors. We conducted a cohort study to determine whether a differential pattern of associations exists between certain factors and breast cancer risk based on birth cohorts., Methods: This was a cohort study using pooled data from 12 cohort studies. We analysed associations between reproductive (menarche age, menopause age, parity and age at first delivery) and lifestyle (smoking and alcohol consumption) factors and breast cancer risk. We obtained hazard ratios (HRs) with 95% confidence intervals (CIs) using the Cox proportional hazard regression analysis on the 1920s, 1930s, 1940s and 1950s birth cohorts., Results: Parity was found to lower the risk of breast cancer in the older but not in the younger birth cohort, whereas lifestyle factors showed associations with breast cancer risk only among the participants born in the 1950s. In the younger birth cohort group, the effect size was lower for parous women compared to the other cohort groups (HR [95% CI] 0.86 [0.66-1.13] compared to 0.60 [0.49-0.73], 0.46 [0.38-0.56] and 0.62 [0.51-0.77]). Meanwhile, a higher effect size was found for smoking (1.45 [1.14-1.84] compared to 1.25 [0.99-1.58], 1.06 [0.85-1.32] and 0.86 [0.69-1.08]) and alcohol consumption (1.22 [1.01-1.48] compared to 1.10 [0.90-1.33], 1.15 [0.96-1.38], and 1.07 [0.91-1.26])., Conclusion: We observed different associations of parity, smoking and alcohol consumption with breast cancer risk across various birth cohorts., (© 2024.

Background: This study had two objectives: first, to examine the association between the history of heartworm preventive purchase compliance and the risk of positive heartworm tests, and second to preliminarily investigate the long-term cardiac outcomes of heartworm disease in dogs that had undergone successful adulticidal therapy., Methods: A retrospective cohort study design was used for both analyses, using anonymous transaction data from Covetrus (retrospective analysis 1) and anonymized medical records from Banfield Pet Hospital (retrospective analysis 2), both including canine patients across the USA. The first analysis examined the relative risk (RR) of a positive heartworm test in dogs with lapses in heartworm preventive purchase history compared to dogs that had no history of a preventive purchase six to 24 months prior to the test. In the second analysis, a long-term evaluation of structured diagnostic codes pertaining to cardiac diseases and risk assessment of outcomes was performed in dogs that had previously been successfully treated for heartworm disease compared to dogs that never had a positive heartworm test., Results: 83,478 unique patients were included in the first analysis. Compared to 32,413 dogs with no history of a heartworm preventive purchase, 44,410 dogs with lapses in monthly preventive purchases had a reduced risk of testing positive for heartworm disease (RR = 0.36, p  < 0.0001). Dogs ( n  = 6,655) with lapses in injectable heartworm preventive administration had a decreased risk of a positive test versus dogs with no preventive purchases (RR = 0.15, p  < 0.0001), as well as versus dogs with lapses in monthly heartworm preventive purchases (RR = 0.28, p  = 0.0024). In the second analysis, 6,138 patients treated for heartworm infection were found to have significantly ( p  < 0.001) elevated risks of right heart failure (RR = 3.59), left heart failure (RR = 1.83), or cardiomyopathy (RR = 2.79) compared to 4,022,752 patients that never had a positive heartworm test., Conclusion: This study highlights the importance of compliance with heartworm preventive guidelines, to reduce the risk of heartworm disease in dogs, which is not only a potentially life-threatening condition in the short-term but also associated with long-term negative cardiac outcomes., Competing Interests: KM, JS, and CA were employees of Zoetis. At the time of study JAM, PL, NS, MY, and ES were employees of Banfield Pet Hospital, the company providing the medical record data. CB was an employee at Covetrus at the time of study, the company providing the transaction data. BPN was paid external consultant to Zoetis.

Abstract: Neuropathic pain is a critical source of comorbidity following spinal cord injury (SCI) that can be exacerbated by immune-mediated pathologies in the central and peripheral nervous systems. In this article, we investigate whether drug-free, biodegradable, poly(lactide- co -glycolide) (PLG) nanoparticle treatment mitigates the development of post-SCI neuropathic pain in female mice. Our results show that acute treatment with PLG nanoparticles following thoracic SCI significantly reduces tactile and cold hypersensitivity scores in a durable fashion. Nanoparticles primarily reduce peripheral immune-mediated mechanisms of neuropathic pain, including neuropathic pain-associated gene transcript frequency, transient receptor potential ankyrin 1 nociceptor expression, and MCP-1 (CCL2) chemokine production in the subacute period after injury. Altered central neuropathic pain mechanisms during this period are limited to reduced innate immune cell cytokine expression. However, in the chronic phase of SCI, nanoparticle treatment induces changes in both central and peripheral neuropathic pain signaling, driving reductions in cytokine production and other immune-relevant markers. This research suggests that drug-free PLG nanoparticles reprogram peripheral proalgesic pathways subacutely after SCI to reduce neuropathic pain outcomes and improve chronic central pain signaling., (Copyright © 2023 International Association for the Study of Pain.)

Background/aims: Endoscopic activity confirmed by enteroscopy is associated with poor clinical outcome in Crohn's disease (CD). We investigated which of the existing biomarkers best reflects endoscopic activity in CD patients including the small bowel, and whether their combined use can improve accuracy., Methods: One hundred and four consecutive patients with ileal and ileocolonic type CD who underwent balloon-assisted enteroscopy (BAE) from October 2021 to August 2022 were enrolled, with clinical and laboratory data prospectively collected and analyzed., Results: Hemoglobin, platelet count, C-reactive protein, leucine-rich alpha-2 glycoprotein (LRG), fecal calprotectin, and fecal hemoglobin all showed significant difference in those with ulcers found on BAE. LRG and fecal calprotectin showed the highest areas under the curve (0.841 and 0.853) for detecting ulcers. LRG showed a sensitivity of 78% and specificity of 80% at a cutoff value of 13 μg/mL, whereas fecal calprotectin showed a sensitivity of 91% and specificity of 67% at a cutoff value of 151 μg/g. Dual positivity for LRG and fecal calprotectin, as well as LRG and fecal hemoglobin, both predicted ulcers with an improved specificity of 92% and 100%. A positive LRG or fecal calprotectin/hemoglobin showed an improved sensitivity of 96% and 91%. Positivity for LRG and either of the fecal biomarkers was associated with increased risk of hospitalization, surgery, and relapse., Conclusions: The biomarkers LRG, fecal calprotectin, and fecal hemoglobin can serve as noninvasive and accurate tools for assessing activity in CD patients confirmed by BAE, especially when used in combination.

Background: Although Lumipulse assays and conventional ELISA are strongly correlated, the precise relationship between their measured values remains undetermined., Objective: To determine the relationship between Lumipulse and ELISA measurement values., Methods: Patients who underwent cerebrospinal fluid (CSF) Alzheimer's disease (AD) biomarker measurements and consented to biobanking between December 2021 and June 2023 were included. The relationship between values measured via Lumipulse assays and conventional ELISA were evaluated by Passing-Bablok analyses for amyloid-β 1-42 (Aβ42), total tau (t-tau), and phospho-tau 181 (p-tau 181). Studies using both assays were systematically searched for in PubMed and summarized after quality assessment., Results: Regression line slopes and intercepts were 1.41 (1.23 to 1.60) and -77.8 (-198.4 to 44.5) for Aβ42, 0.94 (0.88 to 1.01) and 98.2 (76.9 to 114.4) for t-tau, and 1.60 (1.43 to 1.75) and -21.1 (-26.9 to -15.6) for p-tau181. Spearman's correlation coefficients were 0.90, 0.95, and 0.95 for Aβ42, t-tau, and p-tau181, respectively. We identified 13 other studies that included 2,117 patients in total. Aβ42 slope varied among studies, suggesting inter-lab difference of ELISA. The slope and intercept of t-tau were approximately 1 and 0, respectively, suggesting small proportional and systematic differences. Conversely, the p-tau181 slope was significantly higher than 1, distributed between 1.5-2 in most studies, with intercepts significantly lower than 0, suggesting proportional and systematic differences., Conclusions: We characterized different relationship between measurement values for each biomarker, which may be useful for understanding the differences in CSF biomarker measurement values on different platforms and for future global harmonization.

This study aimed to examine the changes that took place between 2015-2019 and 2020 and reveal how the COVID-19 pandemic affected financial contributions from donors. We used the Creditor Reporting System database of the Organization for Economic Cooperation and Development to investigate donor disbursement. Focusing on the Group of Seven (G7) countries and the Bill and Melinda Gates Foundation (BMGF), we analyzed their development assistance for health (DAH) in 2020 and the change in their disbursement between 2015 and 2020. As a result, total disbursements for all sectors increased by 14% for the G7 and the BMGF. In 2020, there was an increase in DAH for the BMGF and the G7 except for the United States. The total disbursement amount for the "COVID-19" category by G7 countries and the BMGF was approximately USD 3 billion in 2020, which was 3 times larger than for Malaria, 8.5 times larger for Tuberculosis, and 60% smaller for STDs including HIV/AIDS for the same year. In 2020 as well, the United States, the United Kingdom, Japan, Italy, and Canada saw their disbursements decline for more than half of 26 sectors. In conclusion, the impact of COVID-19 was observed in the changes in DAH disbursement for three major infectious diseases and other sectors. To consistently address the health needs of low- and middle-income countries, it is important to perform a follow-up analysis of their COVID-19 disbursements and the influence of other DAH areas., Competing Interests: The authors have no conflicts of interest to disclose., (2023, National Center for Global Health and Medicine.)

Objectives　This study was aimed at clarifying characteristics of ethical dilemmas and behaviors in the support process of older adults and their families among nurses at community general support centers.Methods　A self-administered questionnaire survey was mailed to 449 nurses at community general support centers in Tokyo. Question items enquired their age, employment license, years of experience as a nurse, the presence of ethics-related organizations, number of cases in which nurses faced difficulties in supporting older adults and their families in decision making over the past year, the ethical dilemmas they experienced and their situations, and ethical behavior in the process of supporting older adults and their families.Results　From the 143 responses (response rate: 31.8%), 135 (valid response rate: 30.1%) nurses were analyzed. Overall, 43.0% and 27.4% of the participants were in their 50s and 40s, respectively. Of these, 77.0% and 23.0% were nurses and public health nurses, respectively. In total, 52 (38.5%) respondents had an ethics-related organization. The average number of cases in which the respondents faced difficulties in supporting older adults and their families in decision making over the past year was 8.3 (standard deviation, 12.5). Of these, the average number of cases in which they faced difficulties in making ethical decisions was 4.1 (standard deviation, 6.0). Regarding the perception of ethical dilemmas, 113 (83.7%) answered "often" or "sometimes." Ethical dilemma situations included "the intentions of the user and family were different, and I had trouble deciding what to respect" 95 (84.1%); "the user's intention was different from my judgment as a professional, and I had trouble deciding what to respect" 64 (56.6%); and "the intention of the user and neighbors were different, and I had trouble deciding what to respect" 56 (49.6%). Ethical behaviors included "I observe the management rules in my organization regarding personal information data" 116 (85.9%); "I provide easy-to-understand explanations appropriate to the user's situation" 115 (85.2%); and "I decide on a support policy with several staff members when self-decision making is difficult due to the user's situation" 113 (83.7%).Conclusion　More than 80% of the nurses perceived ethical dilemmas. Characteristics of the situations were that users and their families, users and professionals, and users and their neighbors had different intentions. Further research should be conducted on ethical issues related to community-based integrated care.

Racism is a social determinant of mental health which has a disproportionally negative impact on the experiences of psychiatric inpatients of color. Distinct differences in the physical space and clinical settings of two inpatient buildings at a hospital system in the tristate (New York, New Jersey, Connecticut) area of the United States led to the present investigation of racial inequities in the assignment of patients to specific buildings and units. Archival electronic medical record data were analyzed from over 18,000 unique patients over a period of six years. Hierarchical logistic regression analyses were conducted with assigned building (old vs. new building) as the binary outcome variable. Non-Hispanic White patients were set as the reference group. Black, Hispanic/Latinx, and Asian patients were significantly less likely to be assigned to better resourced units in the new building. When limiting the analysis to only general adult units, Black and Hispanic/Latinx patients were significantly less likely to be assigned to units in the new building. These results suggest ethnoracial inequities in patient assignment to buildings which differed in clinical and physical conditions. The findings serve as a call to action for hospital systems to examine the ways in which structural racism impact clinical care., Competing Interests: Declaration of Competing Interest Dr. Kane is a consultant for or receives honoraria from Alkermes, Allergan, Boehringer-Ingelheim, Cerevel, Dainippon Sumitomo, H.

The relationship between charge-transfer (CT) properties and the molecular arrangement formed from π-electronic ion pairs remains unclear because of the limited variety of π-electron anions. This study addressed this issue by synthesising a series of ion pair assemblies composed of viologen dications with diverse alkyl chains as π-electron cations and 1,3-bis(dicyanomethilidene)indan anion (CMI - ) as a stable π-electron anion. We obtained seven ionic crystals and identified their assembled structures using single-crystal X-ray analysis. These structures are categorized into three types: "columnar", "slipped columnar" and "independent". The CT properties were characterised using UV-Vis absorption spectroscopy, which revealed that the CT absorption bands were dependent on the alkyl chain length. This intriguing variation in the CT transitions can be explained by the differences in the type of assembled structure., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)

We aimed to elucidate details of comorbid chronic rhinosinusitis (CRS) in chronic eosinophilic pneumonia (CEP) under the collaboration between otolaryngologists and pulmonologists in a prospective study. The CEP diagnosis was performed by pulmonologists based on clinical symptoms, laboratory findings, and/or eosinophilia detected in bronchoalveolar lavage. All patients were referred to otolaryngologists before undergoing oral corticosteroid treatment for CEP. Ten CEP cases visited to otolaryngologists. All cases showed bilateral sinonasal inflammation in computed tomography (CT), indicating comorbid CRS. Nasal polyps (NPs) were observed in 50% of patients on endoscopy. Eighty percent of patients were diagnosed with eosinophilic CRS. In blood eosinophil levels and the mucosal eosinophil count, there were no significant differences between CRS without and with NPs. In Lund-Mackay CT total scores, among-individual variability was observed in CRS with NPs. The collaboration revealed blood/sinonasal eosinophilia and the variability in Lund-Mackay CT total scores as remarkable findings about the comorbid CRS., Competing Interests: None declared., (© 2023 The Authors.

Dexmedetomidine is a selective α 2 -adrenoreceptor agonist with a broad range of effects, including easily controllable sedation, analgesia and anxiolysis. Because of these favorable features, it has replaced traditional sedatives, such as benzodiazepines, and is becoming the first-line sedative for the patients in intensive care units. Terminally ill patients often need sedatives for symptom management, especially for dyspnoea. However, the use of dexmedetomidine in a palliative care setting has rarely been recognised to date. We experienced a patient nearing the end of life due to uncontrollable pulmonary haemorrhage on ventilator, whose dyspnoea was successfully managed by dexmedetomidine in addition to continuous intravenous infusion of oxycodone., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.
