RESUMO
BACKGROUND: Sarcopenic obesity (SO) is defined as a decrease in lean body mass and an increase in body fat mass (BFM) due to aging. Detecting SO in elderly women is important from the perspective of extending healthy life expectancy. While various indices of SO are currently used, there is no global consensus regarding diagnostic criteria for SO. This study aimed to examine the relationship between obesity indices (waist circumference (WC), body mass index (BMI), and body fat percentage (BFP)) and sarcopenia indices (total body muscle mass (TBM), appendicular lean mass (ALM), skeletal mass index (SMI)), and physical function (gait speed (GS), handgrip strength (HGS)). METHODS: Subjects were 170 community-dwelling healthy elderly women aged 65-79 years (mean: 72.7 ± 5.78 years) who underwent measurements for WC, BMI, and BFP. A WC of ≥ 90cm was defined as the obese group, BMI was determined as weight (kg) divided by height squared (m2) and a cutoff of ≥ 25 kg/m2 was used to define the obesity group. BFM was measured using the bioelectrical impedance analysis (BIA) method and BFP was calculated from body weight and a cutoff of ≥ 30% was used to define the obesity group. TBM and ALM (kg) were measured using the BIA method, ALM (kg) was corrected for height (m2) to obtain SMI (kg/m2). Physical function was assessed by GS and HGS, which were measured by the 5-m walk test and a digital grip strength meter, respectively. RESULTS: When obesity was assessed using BMI, WC and BFP, obese individuals had higher TBM, ALM and SMI, and lower GS among the sarcopenia indicators. HGS did not differ significantly between the non-obese and obese groups. CONCLUSION: Our findings suggest HGS is thought to reflect muscle strength without being affected by obesity indices, suggesting that it may be useful in detecting possible sarcopenia in obese individuals.

Type II diabetes mellitus is a global public health challenge, necessitating robust epidemiological investigations. The majority of evidence reports prevalence as estimations of incidence requiring longitudinal cohort studies that are challenging to conduct. However, this has been addressed by the secondary use of existing health insurance claims data. The current study aimed to examine the incidence of type II diabetes mellitus using existing claims and ledger data. The National Health Insurance and medical care system databases were used to extract type II diabetes mellitus (defined as ICD10 codes E11$-14$) claims data over a period of 5 years for individuals over 40 years old living in one city in Japan. Prevalence was calculated, and insured individuals whose data could be tracked over the entire study period were included in the subsequent analyses. Therefore, annual incidence was calculated by estimating differences in prevalence by year. Data analyses were stratified by sex and age group, and a model analysis was conducted to account for these variables. Overall, the prevalence, diabetes medication usage, and insulin usage were 26.3%, 12.1%, and 2.0%, respectively. Annual incidence of type II diabetes mellitus ranged between 1.2% and 4.6%. Both prevalence and incidence tended to be higher in males and peaked around 60-80 years old. The overall annual incidence was estimated at 3.03% (95% CI: 2.21%-3.85%). The annual incidence was not always associated with a low risk, indicating a consistent risk from middle age onward, although the level of risk varied with age. The current study successfully integrated existing claims and ledger data to explore incidence, and this methodology could be applied to a range of injuries and illnesses in the future.

BACKGROUND: An increased risk of diabetes after COVID-19 exposure has been reported in Caucasians during the early phase of the pandemic, but the effects across viral variants and in non-Caucasians have not been evaluated. METHODS: To address this gap, survival analyses were performed for five outbreak periods. From an anonymized health insurance database REZULT for the employees and their dependents of large companies or government agencies in Japan, 5 matched cohorts were generated based on age, sex, area of residence (47 prefectures), and 7 ranges of medical bills (COVID-19 exposed:unexposed = 1:4). Observation of each matching group began on the same day. Incident diabetes type 1 (T1D) and type 2 (T2D) were defined as the first claim during the target period, including at least 1 year before the start of observation. RESULTS: T1D accounted for 0.8% of incident diabetes after the first COVID-19 exposure, similar to the non-exposed cohort. Most T2D in the COVID-19 cohort was observed within a few weeks. After further adjustment for the number of days from the start of observation to hospitalization (a time-dependent variable), the hazard ratio for incident T2D ranged from 14.1 to 20.0, with 95% confidence intervals (95%CI) of 8.7 to 32.0, during the 2-month follow-ups from the original strain outbreak to the Delta variant outbreak (by September 2021), and decreased to 2.0, with a 95%CI of 1.6 to 2.5, during the Omicron outbreak (by March 2022). No association was found during the BA.4/5 outbreak (until September 2022). Males had a higher risk, and the trend toward higher risk in older age groups was inconsistent across the periods. CONCLUSIONS: Our large dataset, covering 2019-2023, reports for the first time the impact of COVID-19 on incident diabetes in non-Caucasians. The risk intensity and attributes of post-COVID-19 T2D were inconsistent across outbreak periods, suggesting diverse biological effects of different SARS-CoV-2 variants.

BACKGROUND: Previous studies have shown that prenatal maternal smoking and maternal secondhand smoke exposure during pregnancy were associated with an increased risk of wheezing and asthma development. However, few studies have examined the influence of different sources of tobacco exposure in different perinatal timeframes (preconception, prenatal, and postnatal) on wheezing phenotypes in children. Using national survey data from Japan, we investigated the effects of exposure to tobacco smoke during pregnancy on wheezing phenotypes in children before the age of 3 years. METHODS: Pregnant women who lived in the 15 regional centers in the Japan Environment and Children's Study were recruited. We obtained information on prenatal and postnatal exposure to active and secondhand smoke (SHS) and wheeze development up to 3 years of age. Multiple logistic regression analysis was performed to determine the association between tobacco smoke exposure and wheezing phenotypes in children. RESULTS: We analyzed 73,057 singleton births and identified four longitudinal wheezing phenotypes: never wheezing; early transient wheezing (wheezing by age 1 year but not thereafter); late-onset wheezing (wheezing by age 2-3 years but not beforehand); and persistent wheezing. Maternal smoking during pregnancy was significantly associated with early transient and persistent wheezing in children compared with no maternal smoking [early transient wheezing: 1-10 cigarettes per day, adjusted odds ratio (aOR) 1.43, 95% confidence interval (CI) 1.23-1.66; ≥ 11 cigarettes per day, aOR 1.67, 95% CI 1.27-2.20; persistent wheezing: 1-10 cigarettes per day, aOR 1.64, 95% CI 1.37-1.97; ≥ 11 cigarettes per day, aOR 2.32, 95% CI 1.70-3.19]. Smoking cessation even before pregnancy was also significantly associated with increased risk of early transient wheezing, late-onset wheezing, and persistent wheezing in children. Moreover, maternal exposure to SHS during pregnancy was significantly associated with increased risk of early transient and persistent wheezing compared with no such exposure. CONCLUSIONS: Maternal smoking before and throughout pregnancy was associated with wheeze development in children up to 3 years of age. It appears that smoking is detrimental compared to never smoking, regardless of whether individuals quit smoking before or after becoming aware of the pregnancy.

BACKGROUND: Adenocarcinoma of the esophagogastric junction (AEGJ) is most common in men and the elderly, but the disease is becoming more common in female and young adult persons. We have investigated the clinicoepidemiological characteristics of female and young adult patients with AEGJ and the 12-year trends in the Kurashiki area for young adult patients with AEGJ. METHODS: Patients diagnosed with AEGJ in 12 hospitals between January 2008 and December 2019 were included in this study. Patients were divided into three groups by age (young adult [≤50 years], middle-aged [51 to 70 years], and elderly [>70 years]). Factors associated with AEGJ such as obesity, smoking, hiatal hernia and male, which were reported in our previous study, were identified. RESULTS: One hundred and eighty-eight AEGJ patients, including 36 females and 20 young adults, were characterized. There was no significant change in the annual incidence of AEGJ among female (p=0.078) and young adult patients (p=0.89). Female patients without any associated factors, accounting for 53% (19/36) of the female patients and young adult patients, had significantly more histologically undifferentiated cancers than patients with at least one associated factor (58% [11/19] vs. 30% [50/169], p=0.025) and middle-aged and elderly patients (60% [12/20] vs. 30% [25/83] vs. 28% [24/85], p =0.026). Smoking was significantly less common in women than in men (8% [3/36] vs. 57% [87/152], p < 0.01). There were no significant differences between ages in the proportions of these associated factors. CONCLUSIONS: Histologically undifferentiated AEGJ cancers were more frequent in female patients without any associated factors and in young adult patients. Factors associated with AEGJ may differ between women and men, but they are similar in young adults and older adults. No increase in young adult patients with AEGJ was observed in the 12-year study.

OBJECTIVE: Although it has been suggested that a decline in oral function is one of the potential risk factors affecting mild cognitive impairment (MCI), evidence is insufficient to draw clear conclusions. This Japanese cross-sectional study examined the association between tongue pressure (TP) and MCI in middle-aged and older adults aged 36-84 years. METHODS: Study participants were 1019 (368 men and 651 women). TP was evaluated using a TP measurement device. The maximum value of three measurements was used for analysis. MCI was defined as being present if a participant had a Japanese version of the Montreal Cognitive Assessment score of <26. Adjustment was made for age, smoking status, alcohol consumption, leisure-time physical activity, body mass index, hypertension, dyslipidemia, diabetes mellitus, history of depression, number of teeth, employment, education, and household income. RESULTS: The prevalence of MCI was 45.3%. Among women, compared with the lowest tertile of TP, the second and highest tertiles were significantly associated with a lower prevalence of MCI with a clear dose-response relationship; the adjusted odds ratio (95% confidence intervals) in the second and highest tertiles of TP were 0.54 (0.36-0.83) and 0.55 (0.36-0.84), respectively (p for trend = 0.005). In contrast, no statistically significant association was observed between TP and the prevalence of MCI among men. CONCLUSIONS: Our findings suggest that higher TP might be inversely associated with the prevalence of MCI in middle-aged and older Japanese women.

BACKGROUND: Although recent in vitro experimental results have raised the question of whether maternal exposure to per- and polyfluoroalkyl substances (PFAS) may be a potential environmental risk factor for chromosomal abnormalities, epidemiological studies investigating these associations are lacking. OBJECTIVES: This study examined whether prenatal PFAS exposure is associated with a higher prevalence of chromosomal abnormalities among offspring. METHODS: We used data from the Japan Environment and Children's Study, a nationwide birth cohort study, and employed logistic regression models to examine the associations between maternal plasma PFAS concentrations in the first trimester and the diagnosis of chromosomal abnormalities in all births (artificial abortions, miscarriages, stillbirths, and live births) up to 2 years of age. In addition, we examined associations with mixtures of PFAS using multipollutant models. RESULTS: The final sample consisted of 24,724 births with singleton pregnancies, of which 44 confirmed cases of chromosomal abnormalities were identified (prevalence: 17.8/10,000 births). When examined individually, exposure to perfluorononanoic acid (PFNA) and perfluorooctane sulfonic acid (PFOS) showed positive associations with any chromosomal abnormalities with age-adjusted odds ratios of 1.81 (95% CI: 1.26, 2.61) and 2.08 (95% CI: 1.41, 3.07) per doubling in concentration, respectively. These associations remained significant after Bonferroni correction, although they did not reach the adjusted significance threshold in certain sensitivity analyses. Furthermore, the doubling in all PFAS included as a mixture was associated with chromosomal abnormalities, indicating an age-adjusted odds ratio of 2.25 (95% CI: 1.34, 3.80), with PFOS as the predominant contributor, followed by PFNA, perfluoroundecanoic acid (PFUnA), and perfluorooctanoic acid (PFOA). DISCUSSION: The study findings suggested a potential association between maternal exposure to PFAS, particularly PFOS, and chromosomal abnormalities in offspring. However, the results should be interpreted cautiously, because selection bias arising from the recruitment of women in early pregnancy may explain the associations. https://doi.org/10.1289/EHP13617.

This study examined the effects of birth weight on body composition, physical fitness, and sarcopenia in adulthood among young Japanese women. Seventy young adult women (birth weight <2500 g classified as low-birth-weight group [L-BW, n = 13] and ≥2500 g classified as not low-birth-weight group [NL-BW, n = 57]) were evaluated for body composition, physical fitness, and sarcopenia. Skeletal muscle mass was significantly greater (p<0.05) in the NL-BW group than in the L-BW group for all body sites. Effect sizes for the differences in skeletal muscle mass between the two groups were all larger in the NL-BW group than in the L-BW group (0.86-1.44). Knee extension muscle strength was higher in the NL-BW group than in the L-BW group (p = 0.04), but there were no differences between groups with respect to other physical fitness indicators (p>0.05). Except for SMI (p<0.05), other sarcopenia diagnostic evaluations did not differ between the two groups (p>0.05). In conclusion, L-BW female infants were shorter in standing height and smaller in skeletal muscle mass in terms of morphology at the time of young adulthood compared to NL-BW female infants. In addition, in terms of physical fitness, those with L-BW also had a lower-limb power score and a higher proportion of low skeletal muscle mass. Thus, it was suggested that low birth weight infants may be at risk of needing nursing care in old age (i.e., a high predicted incidence of sarcopenia) as well as thinness problems in the fertile generation.

BACKGROUND: Hyaline fibromatosis syndrome (HFS) is a congenital disorder characterized by subcutaneous skin nodules, congenital multiple arthrogryposis, gingival hyperplasia, and chronic pain. The intellectual ability of patients with HFS is generally normal. This syndrome arises from variants of ANTXR2. Thus far, about 100 cases have been reported but few of these were reported from Japan. METHODS: This study reports five additional Japanese patients with genetically confirmed HFS, from unrelatd families, and discusses the clinical course and quality of life of these patients. RESULTS: At our last visit the ages of the patients were 3-19 years (the median age was 5 years). All the patients had arthrogryposis, skin nodules, and gingival hyperplasia, and four patients had chronic pain, all of which are distinctive, clinical characteristics of HFS. Four of the patients (80%) had pruritic skin nodules, and three experienced sleep disruptions due to pruritis. The visceral complications are an index of HFS severity. One patient in the present cohort had a mucosal abnormality without any gastrointestinal symptoms. CONCLUSION: Preventive and routine management of pruritis caused by skin nodules should be shared with the patient's family. Even asymptomatic patients might have endoscopic finding, which would be a soft marker that could predict the development of protein losing enteropathy.

Purpose: Long-term ramifications of the coronavirus disease 2019 pandemic on various care-seeking characteristics of patients with diabetic retinopathy remain unclear. This study aimed to identify risk factors for dropout from regular fundus examinations (RFEs) in patients with diabetic retinopathy in Japan. Methods: We extracted demographic and health checkup data (April 2018 to March 2021) from the JMDC database. Patients with diabetes identified using diagnosis-related and medication codes were included. The dropout and continuation groups included patients who discontinued and continued to undergo RFEs during the coronavirus disease 2019 pandemic, respectively. Results: The number of RFEs was significantly lower during the mild lockdown period (April and May 2020) than during the prepandemic period. Of the 14,845 patients with diabetes, 2333 (15.7%) dropped out of RFEs during the pandemic, whereas before the pandemic, of the 11,536 patients with diabetes, 1666 (14.4%) dropped out of RFEs (P = 0.004). Factors associated with dropout in the multivariate logistic regression analysis included younger age, male sex, high triglyceride levels, high γ-glutamyl transpeptidase levels, smoking habit, alcohol consumption, weight gain of more than 10 kg since the age of 20 years, and certain stages of lifestyle improvement. Factors associated with continuation included low body mass index and high glycosylated hemoglobin levels. Conclusions: Our findings can assist in identifying patients with diabetes at risk of dropout. Translational Relevance: These results have implications for public health and identifying patients with diabetes at risk of dropout. Education and tailored monitoring regimens could be pivotal role in fostering adherence.

BACKGROUND: The prevalence of heart failure is increasing owing to the aging of the population, resulting in growing medical costs and an increasing number of patients with multimorbidity. The optimal management of heart failure by general physicians in addition to internal medicine physicians, such as cardiologists, is essential, although the specifics are unclear. In this study, we aimed to determine the differences in heart failure management outcomes among older patients between those managed by general physicians and those managed by internal medicine physicians, especially in terms of hospitalization and mortality rates. METHODS: This was a retrospective cohort study of patients with heart failure who visited a community hospital in Japan. Patients with heart failure were selected based on International Classification of Diseases codes from electronic medical record data over 9 years, from September 2015 to August 2023. The independent variables were whether a general physician treated the patient; the primary outcome was death; the secondary outcome was hospitalization; and the covariates were patient background, including comorbidities. Multiple logistic regression analysis was used to evaluate the association between being managed by a general physician and death and hospitalization, after adjusting for confounding factors. RESULTS: A total of 1032 patients with heart failure were identified, with a mean age of 82.4 years, and 48.9% were men. Patients treated by general physicians were older, were more likely to have dementia and were more likely to need care than those treated by internal medicine physicians. Being treated by a general physician was significantly negatively associated with death (odds ratio [OR], 0.62) and hospitalization (OR, 0.73). CONCLUSIONS: In Japan, where medical specialties are increasingly differentiated, the comprehensive management of older patients with heart failure and multiple comorbidities by general physicians may reduce hospitalization and mortality rates. Appropriate education of general physicians and an increase in their numbers may prove essential for the successful management of patients with heart failure in aging communities.

INTRODUCTION: It is unclear whether the risk of suicide differs among individuals with only physical health condition, those with only mental health conditions, and those with both types of conditions (multimorbidity) and how emotional social support modifies these associations. This study aimed to examine differences in the association of suicidal ideation with the presence of only physical health conditions, only mental health conditions, and multimorbidity and the modifying role of emotional social support in these associations. METHODS: A cross-sectional survey was conducted between August and September 2023 in a Japanese rural town to collect data. The exposure variable was the health condition, and it was classified into 4 groups: disease-free, only physical health conditions, only mental health conditions, and multimorbidity. The outcome variable was suicidal ideation. The data collected were analyzed using multivariate logistic regression analysis and stratified analysis. RESULTS: Suicidal ideation was found to have a significant positive association with the presence of only mental health conditions and multimorbidity. These associations remained unchanged in the absence of emotional social support. However, the odds ratio for the only mental health conditions group decreased in the presence of emotional social support, while the odds ratio for the multimorbidity group remained significantly higher. CONCLUSIONS: Suicidal ideation is positively associated with the presence of only mental health conditions and multimorbidity, but emotional social support modifies only the association between suicidal ideation and the presence of only mental health conditions. These results suggest that it may be important to identify the type of social support one needs based on one's health condition to prevent suicide.

INTRODUCTION: Malignant wounds are lesions caused by metastasis from distant primary cancers or by direct invasion of the cutaneous structures of a primary cancer, and are most common in patients with breast or head and neck cancers. Malignant wounds not only cause physical symptoms, but also affect survival. Recognizing prognosis in terminal-stage cancer patients is necessary for both patients and health care providers. The prognostic impact of malignant wounds in patients with head and neck cancer has been poorly investigated. METHODS: This is a secondary analysis of the results of a prospective cohort study that investigated the dying process in patients with advanced cancer in 23 palliative care units in Japan. The primary outcome of this study was the prognostic impact of malignant wounds in patients with head and neck cancer. The difference in survival between patients with head and neck cancer who had malignant wounds and those who did not was compared using the log-rank test. RESULTS: Of 1896 patients admitted to palliative care units, 68 had head and neck cancer, and 29 of these had malignant wounds. Overall survival was significantly shorter in patients with malignant wounds than that in those without (median: 19.0 days vs 32.0 days, P = 0.046). CONCLUSION: Patients with head and neck cancer who had malignant wounds had worse overall survival than those who did not.

BACKGROUND: A decline in cognitive function is associated with inflammatory processes. However, the association between high-sensitivity C-reactive protein (hs-CRP) levels and cognitive decline in the Japanese population remains inconclusive. Thus, this study aimed to determine whether hs-CRP is associated with low cognitive function in 70- and 80-year-old community-dwelling Japanese individuals. METHODS: The participants in this cross-sectional study were 872 Japanese residents aged 70 and 80 years who voluntarily participated in the Septuagenarians, Octogenarians, Nonagenarians Investigation with Centenarians (SONIC) study between 2010 and 2011. Blood sample collection, cognitive assessment, and other measurements were performed at the venue. Low cognitive function was defined as a score of 25 points or lower on the Japanese version of the Montreal Cognitive Assessment. The odds ratio (OR) and 95% confidence interval (95% CI) for each hs-CRP quartile were calculated using logistic regression analysis. RESULTS: A total of 288 (69.9%) parsons in the 70-year-old group and 372 (80.9%) in the 80-year-old group exhibited low cognitive function. The association between hs-CRP levels and low cognitive function was significant among 70- and 80-year-old Japanese community-dwelling adults. In particular, the fourth quartile of hs-CRP (0.727-7.420 mg/L) in the 70-year-old group and the second and fourth quartiles (0.214-0.404 and 0.911-9.890 mg/L) in the 80-year-old group were associated with low cognitive function. Furthermore, the third quartile (0.409-0.892 mg/L) in the 80-year-old group was closely associated with low cognitive function. CONCLUSIONS: High hs-CRP levels were associated with lower cognitive function in 70- and 80-year-old Japanese community-dwelling individuals, suggesting that high hs-CRP levels may influence cognitive function.

BACKGROUND: Japan implemented strict border control measures and all incoming passengers were subject to entry screening with reverse transcription-polymerase chain reaction or antigen testing. From late 2020, exit screening within 72 h of departure to Japan also became mandatory. In this study, we evaluated the effectiveness of the exit screening policy in Japan by analyzing airport screening data from October 2020 to April 2022. METHODS: In addition to assessing entry screening data over time of passengers from the United Kingdom, we examined the prevalence of coronavirus disease 2019 (COVID-19) in the United Kingdom based on the Office of National Statistics infection survey. We constructed a statistical model that described entry screening positivity over time using Office of National Statistics prevalence data as the explanatory variable. Ideally, the time-dependent patterns of entry screening and Office of National Statistics prevalence data should resemble each other; however, we found that, sometimes, they were different and regarded the difference to statistically partly reflect the effectiveness of exit screening. RESULTS: The average proportion positive in one month before mandatory exit screening was implemented among Japanese passengers was 0.67% (95% confidence interval [CI]: 0.45, 0.98), whereas the proportion positive decreased to 0.49% (95% CI: 0.21, 1.15) in the first month of exit screening. Adjusting for time-dependent prevalence at the origin, we concluded that exit screening contributed to reducing passenger positivity by 59.3% (95% CI: 19.6, 81.3). The overall positivity values among passengers during the Delta and Omicron variant periods were 3.46 times and 1.46 times that during the pre-Delta variant period, respectively. CONCLUSIONS: We used a simplistic statistical model and empirical data from passengers arriving in Japan from the United Kingdom to support that exit screening helped to reduce the proportion positive by 59%. Although the proportion positive later increased considerably and precluded preventing the introduction of imported cases, submitting a certificate for a negative test result contributed to reducing the positivity among travelers.

Eight peaks of coronavirus disease 2019 (COVID-19) outbreak occurred in Japan, each associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern. The National Epidemiological Surveillance of Infectious Diseases (NESID) analyzed viral genome sequences from symptomatic patients and submitted the results to GISAID. Meanwhile, commercial testing services occasionally sequence samples from asymptomatic individuals. We compared a total of 1248 SARS-CoV-2 full-genome sequences obtained from the SB Coronavirus Inspection Center Corp. (SBCVIC) during Japan's seventh wave, which was dominated by Omicron variants, with 1764 sequences obtained in Japan from GISAID during the same period using chronological phylogenies and molecular transmission networks. The number of SBCVIC sequences was consistent with the number of cases reported by NESID. The SBCVIC detected a shift in the PANGO lineage from BA.2 to BA.5 earlier than that of GISAID. BA.2 lineages from the SBCVIC were distributed at different locations in the transmission network dominated by GISAID entries, whereas BA.5 lineages from SBCVIC and GISAID often formed distinct subclusters. Test-based sentinel surveillance of asymptomatic individuals may be a more manageable approach compared to notifiable disease surveillance; however, it may not necessarily capture all infection populations throughout Japan.

Vaccination is associated with a reduced risk of post-coronavirus disease (COVID-19) condition (PCC). Here, risk factors including vaccination for PCC in the Omicron-dominant waves among Japanese adults were investigated. This was a registry-based matched case-control study of individuals aged 18-79 years diagnosed with COVID-19 registered in a National database between March 2021 and April 2022 and matched noninfected individuals living in Yao City, Japan. A self-administered questionnaire was used to assess persistent symptoms and their risk factors. The COVID-19 vaccination status was obtained from the Vaccination Registry. PCC risk factors were analyzed using logistic regression after adjusting for potential confounding factors. Overall, 4185 infected (cases) and 3382 noninfected (controls) individuals were included in the analysis. The mean ages and proportions of women were 44.7 years and 60.2% and 45.5 years and 60.7% for cases and controls, respectively. A total of 3805 (90.9%) participants had asymptomatic or mild acute symptoms at the median (range) follow-up of 271 (185-605) days. The prevalence of PCC was 15.0% for cases while that of persistent symptoms was 4.4% for controls; among the cases, it was 27.0% in the Alpha- and Delta-dominant waves and 12.8% in the Omicron-dominant wave. Female sex, comorbidities, and hospitalization were positively associated with PCC. One or more vaccine doses of vaccination were inversely associated with PCC; the inverse association was stronger in the Alpha- and Delta-dominant waves (adjusted odds ratio [aOR]: 0.29, 95% confidence interval [CI]: 0.12-0.73) than in the Omicron-dominant wave (aOR: 0.79, 95% CI: 0.59-1.07).

BACKGROUND: Higher-level functional capacity (HLFC) is crucial for the independent living of older adults. While internet use positively impacts the health of older adults, its effect on HLFC and how this effect varies with educational attainment remains uncertain. OBJECTIVE: This longitudinal study aimed to investigate whether internet use could mitigate the risk of HLFC decline and if this benefit extends to older adults with lower levels of education. METHODS: The data were sourced from the Japan Gerontological Evaluation Study (JAGES), encompassing 8050 community-dwelling adults aged 65 years and older from 2016 to 2019. The study focused on those who remained self-sufficient from 2016 to 2019, identifying participants with independent HLFC in 2016. The Tokyo Metropolitan Institute of Gerontology Index of Competence defined HLFC operationally, consisting of 3 subscales, namely instrumental activities of daily living, intellectual activity, and social role. The primary variable was the frequency of internet use in 2016; participants who reported using the internet were classified as internet users, while those who answered "No" were identified as nonusers. The study compared the effects of internet use on HLFC decline across educational levels of ≤9 years, 10-12 years, and ≥13 years using Poisson regression analysis adjusted for robust SE to calculate the risk ratio (RR) and 95% CI for HLFC decline in 2019. RESULTS: After adjusting for demographic and health condition risk factors, internet use was significantly linked to a decreased risk of HLFC decline in older adults over 3 years, including those with lower educational levels. Internet users with ≤9 years of educational attainment experienced a suppressed decline in the total score (RR 0.57, 95% CI 0.43-0.76; P<.001); instrumental activities of daily living (RR 0.58, 95% CI 0.38-0.91; P=.02), intellectual activity (RR 0.60, 95% CI 0.41-0.89; P=.01), and social role (RR 0.74, 95% CI 0.56-0.97; P=.03) compared with nonusers. Participants with 10-12 years of education showed suppression rates of 0.78 (95% CI 0.63-0.98; P=.03), 0.59 (95% CI 0.39-0.90; P=.01), 0.91 (95% CI 0.63-1.31; P=.61), and 0.82 (95% CI 0.68-1.00; P=.05), respectively, and those with ≥13 years displayed suppression rates of 0.65 (95% CI 0.51-0.85; P=.001), 0.55 (95% CI 0.36-0.83; P=.01), 0.64 (95% CI 0.37-1.10; P=.11), and 0.83 (95% CI 0.64-1.08; P=.17), respectively. CONCLUSIONS: These findings indicate that internet use supports the maintenance of HLFC independence in older adults with higher education and those with lower educational levels. Encouraging internet use among older adults with lower levels of education through future policies could help narrow functional health disparities associated with educational attainment.

BACKGROUND: It is still unclear whether body mass index (BMI) affects bleeding and cardiovascular events in patients requiring oral anticoagulants (OAC) for atrial fibrillation (AF) and antiplatelet agents after percutaneous coronary intervention (PCI) for coronary artery disease (CAD). The aim of this study was to evaluate the relationship between BMI and clinical events in patients who underwent PCI under OAC therapy for AF. METHOD: This was a multicenter, observational cohort study conducted at 15 institutions in Japan. AF patients who underwent PCI with drug-eluting stents for CAD were retrospectively and prospectively included. Patients were divided into the Group 1 (BMI <21.3 kg/m2) and the Group 2 (BMI ≥21.3 kg/m2) according to the first-quartile value of BMI. The primary endpoint was net adverse clinical events (NACE), a composite of major adverse cardiovascular events (MACE) and major bleeding events within one year after index PCI procedure. RESULTS: In the 720 patients, 180 patients (25.0%) had BMI value <21.3 kg/m2. While the rates of NACE and MACE were significantly higher in the Group 1 than the counterpart (21.1% vs. 11.9%, p = 0.003 and 17.2% vs. 8.9%, p = 0.004), that of major bleeding did not differ significantly between the 2 groups (5.6% vs. 4.3%, p = 0.54). The cumulative rate of NACE and MACE was significantly higher in the Group 1 than the Group 2 (both log-rank p = 0.002), although that of major bleeding events was equivalent between the 2 groups (log-rank p = 0.41). In multivariable Cox regression analyses, while BMI value <21.3 kg/m2 was not associated with major bleeding events, that cut-off value was an independent predictor for increased NACE and MACE. CONCLUSIONS: Among the patients undergoing PCI for CAD and requiring OAC for AF, BMI value was a useful indicator to predict major adverse clinical events.

Treatment trends for newly diagnosed multiple myeloma (NDMM) are not fully evaluated in real-world settings in the Japanese population. Triple-class exposed (TCE) patients with relapsed or refractory MM have a poor prognosis and limited treatment options. To clarify characteristics, treatment trends, and TCE status in Japanese patients with MM, we conducted a retrospective, non-interventional study. Data from patients with MM were extracted from a Japanese claims database between 2015 and 2022: this study identified patients with NDMM prescribed daratumumab (D), lenalidomide (R), and/or bortezomib (V) as 1st-line treatment. The patient characteristics and treatment trends were analyzed for non-transplant and transplant groups. Of 1,784 patients, non-transplant patients (n = 1,656, median age 75 years [range: 37-94]) received R+dexamethasone (Rd) (24.7%), Vd (23.8%), and RVd (15.6%) and transplant patients (n = 128, median age 61 years [range: 35-73]) received RVd (49.5%), Vd (18.7%), and DVd (8.4%) in 1st line. In the non-transplant group, the commonly prescribed treatment regimens were Rd for patients aged ≥75 years, Vd for patients aged 65-74 years, and RVd for patients aged <65 years. Patients with renal or cardiac dysfunction commonly received Vd or Rd, respectively. In the transplant group, 107 (83.6%) and 20 (15.6%) patients received transplantation in the 1st and 2nd lines, respectively. The top three regimens as induction therapy before stem cell transplantation were RVd (49.5%), Vd (18.7%), or DVd (8.4%) in 1st line. Cumulative TCE patients by 5th line were 351 (21.2%) and 56 (43.8%) for non-transplant and transplant patients, respectively. TCE ratio at each line gradually increased from 1st to 5th line (11.1-69.2% in the non-transplant group and 21.1-100% in the transplant group, respectively). Of 184 TCE patients in the non-transplant group, 89.7% received sequencing treatments including DRd, RVd, and DVd, and 10.3% received D-RVd in 1st line.
