Background: The choroid plexus (CP) is involved in neurodegenerative diseases. However, the association of CP with cardiovascular risk factors and cerebral small vessel disease in older adults remains unclear., Methods and Results: This population-based study included 1263 participants (60 years and older) from the MIND-China (Multimodal Interventions to Delay Dementia and Disability in Rural China) substudy (2018-2020), of which 111 individuals completed diffusion tensor imaging examination. CP volume was automatically segmented. White matter hyperintensities (WMHs), enlarged perivascular spaces (EPVS), cerebral microbleeds, and lacunes were assessed following the Standards for Reporting Vascular Changes on Neuroimaging 1. Peak width of skeletonized mean diffusivity and free water were derived from diffusion tensor imaging images. We used linear regression models to evaluate the association between CP volume and cardiovascular risk factors, WMH volumes, and diffusion tensor imaging metrics, and logistic regression models to examine the association between CP volume and EPVS, cerebral microbleeds, and lacunes. The CP volume increased with age ( P <0.001). Men (β coefficient=0.47 [95% CI, 0.29-0.64]) and participants with diabetes (β coefficient=0.16 [95% CI, 0.01-0.31]) had larger CP volumes than women and individuals without diabetes, respectively ( P <0.05). Greater CP volume was significantly associated with larger total and periventricular WMH volumes and moderate to severe EPVS in basal ganglia ( P <0.05) but not with deep WMHs, EPVS in centrum semiovale, lacunes, or cerebral microbleeds. In the diffusion tensor imaging subsample, enlarged CP was significantly associated with higher peak width of skeletonized mean diffusivity and free water of periventricular and deep white matter ( P <0.05)., Conclusions: An enlarged CP is associated with larger global and periventricular WMH volume and higher likelihoods of EPVS in basal ganglia and impaired white matter integrity, suggesting that an enlarged CP may represent a precursor of cerebral small vessel disease.

Purpose: Adolescent and young adult (AYA) patients with breast cancer generally have poor prognoses and a higher risk of secondary cancers compared to those at the same cancer stage. Notably, AYA patients in Asia exhibit a higher incidence rate of breast cancer, with Luminal A as the predominant molecular subtype, which contrasts with the trends observed in Western countries. This study aims to compare the efficacy of Taxane/Anthracycline combination-based regimens (TACB) versus Anthracycline-based regimens (AB) in AYA patients with stage I-II breast cancer, focusing on different molecular subtypes., Methods: This study utilized data from the Taiwan National Health Insurance Research Database (NHIRD) and the Taiwan Cancer Registry (TCR) from 2011 to 2019. The study cohort included patients aged 15 to 39 years who were diagnosed with stage I-II breast cancer and received either TACB or AB regimens. Propensity score matching and Cox proportional hazards regression models were used to calculate the hazard ratios (HR) for recurrence., Results: The results showed that TACB regimens significantly reduced the risk of recurrence compared to AB regimens across all patients (aHR 0.73, 95% CI 0.55-0.97). Specifically, for low/middle-recurrence risk groups, the aHR was 0.68 (95% CI 0.49-0.96), and for high-recurrence risk groups, it was 0.43 (95% CI 0.21-0.87). The analysis further indicated no significant differences in recurrence risk between AYA and non-AYA patients using TACB regimens., Conclusion: The TACB regimens showed a more favorable prognosis than AB regimens across all molecular subtypes. Furthermore, TACB regimens not only outperformed AB treatments but also closed the gap in prognostic outcomes between AYA and non-AYA patients. We believe the findings of this study are highly reliable and can provide valuable guidance for physicians in choosing the most appropriate treatment strategies for AYA patients with stage I-II breast cancer., (© 2024.

Study Question: Is there an association between male creatinine levels and time to pregnancy (TTP) in couples planning pregnancy?, Summary Answer: Low and high male creatinine concentrations were associated with reduced couple fecundity., What Is Known Already: Abundant evidence suggests male creatinine dysfunction is associated with infertility in males with kidney diseases. However, the association of preconception creatinine levels with reduced fecundity among general reproductive-aged couples lacks evidence from an in-depth population study., Study Design, Size, Duration: Based on the population-based cohort study from the National Free Preconception Check-up Projects, 4 023 204 couples were recruited and met the inclusion criteria from 1 January 2015 to 31 December 2017. They were planning pregnancy and were followed up every 3 months until achieving pregnancy as detected by gynaecological ultrasonography or were followed up for 1 year for the analysis of TTP., Participants/materials, Setting, Methods: Cox regression models were used to estimate hazard ratios (HRs) and 95% CI for creatinine deciles. Restricted cubic spline regression was adopted for the dose-response relationship of creatinine with HRs. R statistical software was used for data analysis., Main Results and the Role of Chance: Of the included participants, 2 756 538 (68.52%) couples successfully conceived. The median male serum creatinine was 81.50 μmol/l. Compared with the reference group (78.00-81.49 μmol/l) including the median creatinine, fecundity in the first (≤64.89 μmol/l), second (64.90-69.99 μmol/l), third (70.00-73.99 μmol/l), and tenth (≥101.00 μmol/l) deciles decreased by 8%, 5%, 2%, and 1%, respectively (Decile 1 Adjusted HR 0.92, 95% CI 0.91-0.92; Decile 2 Adjusted HR 0.95, 95% CI 0.95-0.96; Decile 3 Adjusted HR 0.98, 95% CI 0.97-0.99; Decile 10 Adjusted HR 0.99, 95% CI 0.98-0.99). An inverse-U-shaped association was consistently presented among males such that non-inferiority for fecundity was shown when creatinine was in the 81.66-104.90 μmol/l range (P for non-linearity < 0.001). For males over 40 years old, the risk of fecundity impairment was more obvious and the recommended range of creatinine levels for TTP was reduced and more narrow, compared with that for younger males., Limitations, Reasons for Caution: Not including the time couples spend preparing for pregnancy before enrolment would lead to an overestimation of fecundity; additionally some couples place pregnancy plans on hold due to special emergencies, which would not have been recognized. Due to the lack of information regarding semen quality, psychological factors, sexual intercourse frequencies, and hazardous environmental factors, we could not adjust for these factors. Some variates were self-reported and dichotomized, which were prone to bias. Direct variables reflecting muscle mass and impaired kidney function were lacking. Thus, extrapolation should be done with caution., Wider Implications of the Findings: Male creatinine is associated with couples' fecundity and the relationship varied by age. This study provides a better understanding of the potential implications and significance of different creatinine levels and their association with the clinical significance regarding couples' fecundity., Study Funding/competing Interest(s): This research has received funding from the National Natural Science Foundation of China (Grant No. 81872634), the Basic Research Funds of Central Public Welfare Research Institutes of China (Grant No. 2023GJZ03), the National Key Research and Development Program of China (Grant No. 2016YFC1000307), and the Project of National Research Institute for Family Planning (Grant No. 2018NRIFPJ03), People's Republic of China.

Purpose: To assess associations between atrial fibrillation/atrial flutter (AF) and ocular parameters and diseases., Methods: The population-based Ural Eye and Medical Study (UEMS) and the Ural Very Old Study (UVOS) included 4894 individuals (age: 40+ years) and 835 individuals (age: 85+ years), respectively., Results: In the UEMS, AF prevalence (80/4894; 1.6%; 95% CI: 1.3, 2.0) increased from 1/1029 (0.1%) in the age group of 40 to <50 years to 29/619 (4.7%) and 12/159 (7.5%) in the age groups of 70 to <80 years and 80+ years, respectively. Higher AF prevalence correlated with older age (OR: 1.08; 95% CI: 1.04, 1.12; p < 0.001), urban region of habitation (OR: 1.08; 95% CI: 1.04, 1.12; p < 0.001), higher prevalence of cardiovascular disease/stroke (OR: 2.50; 95% CI: 1.32, 4.72; p < 0.001) and lower prevalence of neck pain (OR: 0.35; 95% CI: 0.14, 0.85; p = 0.02), higher serum concentration of bilirubin (OR: 1.03; 95% CI: 1.02, 1.05; p < 0.001) and lower prothrombin index (OR: 0.96; 95% CI: 0.93, 0.99; p = 0.003), higher stage of arterial hypertension (OR: 1.52; 95% CI: 1.01, 2.28; p = 0.04) and higher ankle-brachial index (OR: 22.1; 95% CI: 4.45, 1.10; p < 0.001). In that model, AF prevalence was not associated with ocular parameters such as intraocular pressure (p = 0.52), retinal nerve fibre layer thickness (p = 0.70), refractive error (p = 0.13), axial length (p = 0.14), nuclear cataract degree (p = 0.50) and prevalence (p = 0.40), cortical cataract degree (p = 0.43) and presence (p = 0.17), lens pseudoexfoliation (p = 0.58), status after cataract surgery (p = 0.38), age-related macular degeneration prevalence (p = 0.63), open-angle glaucoma presence (p = 0.90) and stage (p = 0.55), angle-closure glaucoma prevalence (p = 0.99) and stage (p = 0.99), diabetic retinopathy prevalence presence (p = 0.37) and stage (p = 0.32), and myopic macular degeneration (p = 0.98). In the UVOS, similar results were obtained., Conclusions: In these multi-ethnic populations from Russia, AF prevalence was not associated with any major ocular disease and may not play a major role in the pathogenesis of these disorders., (© 2024 Acta Ophthalmologica Scandinavica Foundation.

Objective: To investigate the associations between time interval from myomectomy to pregnancy (TIMP) and subsequent pregnancy and obstetric complications, and to explore whether these associations vary according to maternal age at birth., Methods: A retrospective population-based cohort study was conducted from 2008 to 2017. Data were extracted from the National Health Insurance Research Database and the Taiwan Maternal and Child Health Database, comprising 2024 379 births from 1 391 856 pregnancies. Eligible cases were identified using diagnostic and procedure codes; 4006 first singleton births in 4006 women after their first laparotomic myomectomy were identified. We estimated the risks of pregnancy and obstetric outcomes according to TIMP (<6, 6-11, and ≥12 months). Subgroup analysis was performed by further dividing according to maternal age at birth (18-34 vs ≥35 years old)., Results: We observed higher risks of gestational hypertensive disorders (adjusted odds ratio [aOR] 1.97, 95% confidence interval [CI] 1.22-3.18, P = 0.005) and neonatal death (aOR 4.59, 95% CI 1.49-14.18, P = 0.008) for TIMP of <6 months versus TIMP of 6-11 months. Likewise, a TIMP ≥12 months was associated with increased risks of gestational hypertensive disorders (aOR 1.72, 95% CI 1.14-2.58, P = 0.010), and neonatal death (aOR 3.27, 95% CI 1.16-9.24, P = 0.025) versus a TIMP of 6-11 months. In subgroup analysis, women over 35 years old still had higher risks of gestational hypertensive disorders when TIMP was <6 months (aOR 2.26, 95% CI 1.17-4.37, P = 0.015) or ≥12 months (aOR 2.04, 95% CI 1.17-3.54, P = 0.012), and a higher risk of neonatal death when TIMP was <6 months (aOR 4.05, 95% CI 1.06-15.53, P = 0.041); whereas women aged 18-34 years old did not., Conclusions: This study suggests that a TIMP between 6 and 11 months is associated with lower risks of gestational hypertensive disorders and neonatal death compared with a TIMP <6 months or ≥12 months, especially for women over 35 years old., (© 2024 International Federation of Gynecology and Obstetrics.)

Background: Chronic kidney disease (CKD) is a prevalent condition in Taiwan, and the incidence of total knee arthroplasty (TKA) is on the rise. This study aimed to evaluate the postoperative results of patients with different degrees of CKD after TKA, using data from the Taiwan National Health Insurance Research Database., Methods: The study analyzed 3078 patients who received TKA from 2012 to 2017, equally divided into three groups: none-CKD, mild CKD (without dialysis), and severe CKD (with dialysis). Propensity score matching was used to minimize selection bias., Results: After TKA, there was no significant difference in the risk of debridement surgery for infection between the three groups (adjusted HR of mild CKD: 0.71 95% CI=0.36-1.38, p=0.3073; adjusted HR of severe CKD: 1.14, 95% CI=0.63-2.06, p=0.6616). However, CKD patients requiring dialysis had a significantly higher risk of mortality (adjusted HR: 1.98, 95% CI=1.57-2.50, p<0.001) and readmission within 90days of any causes (adjusted HR: 1.83, 95% CI=1.48-2.26, p<0.001) than non-CKD and mild CKD patients., Conclusion: Severe CKD patients needing dialysis after TKA have a higher risk of mortality and readmission rates than that of the non-CKD or mild CKD patients. If the patient is in the early stage of CKD, their prognosis after receiving TKA is expected to be as good as non-CKD patients., Level of Evidence: IV; well-designed cohort study., (Copyright © 2024.

The frequency of behavioral and psychological symptoms of dementia (BPSD) is high, and it is a challenge to elucidate its neural substrates underlying their development. In recent years, many findings have been reported on the relationship between BPSD and brain volume in dementia patients. However, the results are not fully conclusive. Furthermore, there have been few population-based studies. Therefore, the relationship between BPSD and brain volume was investigated as an exploratory study. Of the 927 older persons who participated in the fifth Nakayama study, 90 were included in this analysis, consisting of 52 patients with mild cognitive impairment and 38 patients with dementia, with head MRI and the Neuropsychiatric Inventory (NPI) data. Multiple regression analysis was used to examine the association between the total score of each BPSD score on the NPI and brain volume estimated by FreeSurfer. On multivariate adjustment, even after false discovery rate correction, insular cortical volumes decreased significantly as total scores for apathy/indifference increased (p value = 0.002, q-value = 0.01). Similarly, total brain volume decreased significantly as total scores for appetite and eating disturbance increased (p value = 0.03), and parietal, temporal, and hippocampal cortical volumes also decreased significantly as total scores for appetite and eating disturbance increased (all p and q values < 0.05). This study's results suggest that apathy is negatively correlated with insular cortical volume, and that appetite and eating disturbance are also correlated with brain regions, including parietal, temporal, and hippocampal volume in a community-dwelling older population., (© 2024.

Background: The structural brain alterations for subjective cognitive decline (SCD) and mild cognitive impairment (MCI) are poorly defined. We sought to characterize grey matter volume (GMV) and cortical thickness associated with SCD and MCI among rural-dwelling older adults in China., Methods: This population-based cross-sectional study included 1072 dementia-free participants from the brain MRI sub-study of MIND-China (2018-2020). We defined MCI following the Petersen's criteria, and SCD as the self-rated Ascertain Dementia 8-item Questionnaire score ≥ 2. Data were analyzed using voxel-based morphometry (VBM), surface-based morphometry analysis (SBM), and logistic regression models., Results: SCD was defined in 243 persons and MCI in 246 individuals. The VBM analysis showed that MCI (vs. normal cognition) was significantly associated with reduced GMV in brain regions such as the bilateral parahippocampus, bilateral hippocampus, and bilateral fusiform (P < 0.05), but SCD exhibited no significant differences with normal cognition in GMV (P > 0.05). The ROI-wise SBM analysis revealed that SCD was significantly associated with cortical thinning in the right paracentral sulcus, left caudal middle frontal gyrus, and left entorhinal cortex (P < 0.05) and that MCI was significantly associated with cortical thinning in the left temporal lobe, left frontal lobe, bilateral parietal lobe and bilateral fusiform (P < 0.05)., Conclusions: The brain regions with reduced GMV or cortical thickness in older adults gradually expand from normal cognition through SCD to MCI, suggesting that characterizing structural brain alterations may help define the cognitive spectrum at the pre-dementia phase. These findings have potential implications for understanding the neuropathological process of cognitive deterioration in aging., (Copyright © 2024 The Authors. Published by Elsevier Inc.

Background: Pregnancies conceived through assisted reproduction have been associated with increased risks of adverse pregnancy and delivery outcomes, including cervical insufficiency (CI). Despite CI being a significant cause of late miscarriage or preterm birth, there are minimal published data on the associations of infertility (with or without fertility treatment) with CI. This study uses Swedish national health registers to examine the associations between infertility, assisted reproduction and CI in nulliparous women., Methods: This population-based case-control study is based on data from Swedish national health registers. Using the information on parity and multiple gestation in the Medical Birth Register, singleton pregnancies of nulliparous women were extracted and linked to the National Patient Register and the National Quality Register for Assisted Reproduction. Using diagnostic codes for CI and procedural codes for cervical cerclage, a total of 2662 CI cases were identified for deliveries in the 21-year period, 1992-2012. A reference group of 26,620 controls were extracted from the population of non-cases using simple random sampling.. Infertility was classified using a woman's report of difficulty conceiving for at least one year. Fertility treatment was assessed through self-reported variables in the Medical Birth Register and fertility treatment registration in the National Quality Register for Assisted Reproduction., Results: On adjusting for maternal characteristics and medical history, infertility was associated with CI, overall (adjusted odds ratio (aOR) ) 1.91 (1.53, 2.39) and in the subgroup of non-users of fertility treatment (aOR) 1.60 (1.21, 2.12), compared to women without infertility. Among women with infertility, pregnancies conceived with the aid of fertility treatment had higher risk of CI than naturally-conceived pregnancies (aOR 1.49 (1.05, 2.10). In the subgroup of women with infertility and no history of miscarriage, the use of fertility treatment was associated with CI (aOR 3.48 (2.02. 5.98)). No association was found between fertility treatment and CI in the pregnancies of women with infertility and a history of miscarriage., Conclusions: From this study, we conclude that CI in nulliparous women is associated with both infertility and its treatment. For infertile women, the risk of CI following fertility treatment was seen only in those with no history of miscarriage, providing crucial information for improving risk assessment and management strategies for preterm birth prevention in populations availing of fertility treatment., (Copyright © 2024 The Author(s).

Background: In recent decades, new first and subsequent lines of anticancer treatment and supportive care have improved survival for children with cancer. We investigated recent temporal changes in the incidence of relapse and survival after relapse among children with cancer in Denmark., Procedure: This register-based study included 2890 children diagnosed before age 15 years with haematological cancers and solid tumours (2001-2021) and central nervous system (CNS) tumours (2010-2021). We used the Aalen-Johansen and Kaplan-Meier estimators to assess cumulative incidence of relapse-defined as cancer recurrence or progression-and survival probability after relapse., Results: Comparing the periods 2001-2010 and 2011-2021, the 5-year cumulative incidence of relapse decreased from 14% to 11% among children with haematological cancers (p = .07), and from 21% to 18% among children with solid tumours (p = .26). Concurrently, the 5-year survival after relapse increased among children with haematological cancers (from 44% to 61%, p = .03) and solid tumours (from 38% to 46%, p = .25). Among children with malignant CNS tumours, the 5-year cumulative incidence of relapse and the 5-year survival after relapse remained stable (49% and 51%, p = .82; and 20% and 18%, p = .90) comparing 2010-2015 and 2016-2021., Conclusions: In recent decades in Denmark, improvements were observed in reducing relapse incidence and increasing survival after relapse in children with haematological cancers and solid tumours. However, the persistent survival gap between children who relapse and those who do not across all childhood cancers underlines the need for intensified and highly targeted treatments for children at high risk of relapse., (© 2024 The Author(s).

Background: Lung cancer (LC) is Europe's primary cause of cancer-related mortality largely due to its historically low survival rates. The aim of this study was to analyze 26-year survival trends in the province of Girona, Spain, and to identify key prognostic factors., Methods: Population-based study of LC cases collected between 1994 and 2019, with follow-up until December 31, 2021. Variables included date of diagnosis, sex, age, histology, and tumor stage (the latter since 2010). Diagnosis dates were categorized into three periods (1994-2002, 2003-2011, and 2012-2019). Multivariate flexible parametric models, incorporating age as a non-linear, time-varying covariate, were used to analyze net survival (NS) and trends. Annual absolute change in survival (AAC&#95;S) was calculated using 3-year NS., Results: The analysis of 9,113 LC cases showed a NS improvement between the first and last period (7.1 months (95 %CI: 6.5;7.6) to 8.5 months (95 %CI: 7.9;9.1)). Squamous cell carcinoma (NSC-SCC) showed the greatest improvement with an AAC&#95;S of 0.32 % (95 % CI: 0.21; 0.43), while survival for non-small cell lung cancer not otherwise specified declined (AAC&#95;S of -0.19 % (95 %CI: -0.26; -0.12)). Prognostic analysis of the 3,642 cases (2010-2019) indicated a lower LC death risk for adenocarcinoma and NSC-SCC compared to LC not otherwise specified (HR 0.52 and 0.62, respectively). Increasing tumor stage correlated with higher LC mortality risk (1.8-, 4.0-, and 10.1-fold increase for stage II, III, and IV, respectively, compared to stage I)., Conclusions: LC survival has notably improved, particularly for NSC-SCC. Survival is influenced by sex, age, date of diagnosis, tumor histology and especially by stage, underscoring comprehensive data collection's importance., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Aim: To describe the distribution of ocular biometrics and to evaluate its associations with refractive error and to assess the contribution from ocular parameters to refractive error among Chinese myopic children., Methods: This cross-sectional study evaluated subjects aged 8-12y. Keratometry, ocular biometry, and cycloplegic autorefraction were performed on each subject. Spherical equivalent refraction (SER) and ocular biometrics were assessed as a function of age and gender. The Pearson correlation analysis between SER and ocular biometrics was carried out. Multiple linear regression was performed to analyze the association between SER and ocular parameters., Results: A total of 689 out of 735 participants (321 boys, 48.1%) were analyzed, with a mean SER of -2.98±1.47 diopter (D). Axial length (AL), anterior chamber depth (ACD), corneal radius of curvature (CR), horizontal visible iris diameter (HVID), central corneal thickness (CCT) and lens power (LP) showed normal distribution. The AL, AL/CR ratio, ACD and CR increased from 8 to 12y of age, while SER and LP decreased, HVID and CCT remained stable. There was no difference in gender. SER decreased by 0.929 D for every 1 mm increase in AL and decreased by 1.144 D for every 0.1 increase in AL/CR ratio. The Pearson correlation coefficient between SER and AL was -0.538 ( P <0.01) and -0.747 ( P <0.01) between SER and AL/CR ratio. For the SER variance, AL explained 29.0%, AL/CR ratio explained 55.7%, while AL, CR, ACD and LP explained 99.3% after adjusting for age and gender., Conclusion: The AL, CR, ACD and LP are the most important determinants of myopic refractive error during myopia progression., Competing Interests: Conflicts of Interest: Tang T, None; Chen ST, None; Zhao H, None; Wang K, None; Zhao MW, None., (International Journal of Ophthalmology Press.)

Purpose: To examine the prevalence of self-reported cataract and cataract surgery, and the incidence of cataract surgery, in relation to smoking and use of the moist smokeless tobacco product snus., Methods: In 2014/2015, individuals born in 1951 (n = 18 055) in the Västra Götaland County, Sweden, were invited to participate. Of these, 9743 (54%) accepted participation and 9316 (52%) remained after exclusion criteria were applied. Participants answered a questionnaire with items about eye conditions, smoking, snus, gender, education, asthma, chronic obstructive pulmonary disease, corticosteroid use, diabetes mellitus, weight and height. Prevalence ratios (PRs) for self-reported cataract and cataract surgery were calculated. The incidence of cataract surgery was assessed, and hazard ratios (HRs) were presented., Results: Having ever smoked was associated with a higher prevalence ratio of self-reported cataract (PR 1.19, 95% confidence interval [CI] 1.04-1.35) and cataract surgery (PR 1.27, 95% CI 1.06-1.53), compared to those who had never been daily smokers. Currently, a smoker was associated with a higher HR of cataract surgery (HR 1.34, 95% CI 1.04-1.74), as well as having been a former smoker (HR 1.27, 95% CI 1.03-1.56). Total years of smoking were associated with an increased risk for cataract surgery (HR 1.05, 95% CI 1.02-1.08 for 5 years of smoking). Snus use was not associated with an increased prevalence of cataract or incidence of cataract surgery, except among women who were current snus users (HR for cataract surgery 2.04, 95% CI 1.16-3.60 n = 108)., Conclusion: Smoking is associated with a higher prevalence of cataracts, and a higher incidence of cataract surgery, indicating a dose-response relationship. However, there was no firm association between snus use and cataract., (© 2024 The Author(s).

Background: The association between aspirin use and the risk of intracerebral hemorrhage (ICH) among individuals without previous stroke events is inconclusive., Aim: We investigated the association between regular aspirin use and ICH risk in middle-aged and older adults without previous stroke or transient ischemic attack (TIA)., Methods: This prospective population-based study included participants older than 40 years with no history of stroke or TIA from the UK Biobank. The main exposure was regular aspirin use. Cox regression analyses and propensity score matching analyses estimated the hazard ratios (HRs) for aspirin use for incident fatal and non-fatal ICH. We conducted pre-specified subgroup analyses for selecting individuals at high risk of ICH when using aspirin. Multiple sensitivity analyses were performed to test the robustness of our results., Results: A total of 449,325 participants were included into final analyses (median (IQR) age 58 (50-63) years, 54.6% females), of whom 58,045 reported aspirin use. During a median follow-up of 12.75 (IQR: 12.03-13.47) years, 1557 (0.3%) incident ICH cases were identified, of which 399 (25.6%) were fatal. Aspirin was not associated with increased risk of overall (hazard ratio (HR): 1.11, 95% confidence interval (CI): 0.95-1.27, P  = 0.188), fatal (HR: 1.03, 95% CI: 0.78-1.36, P  = 0.846) and non-fatal (HR: 1.12, 95% CI: 0.95-1.33, P  = 0.186) ICH. Propensity score matching analysis showed similar results. Subgroup analysis indicated that aspirin use in individuals older than 65 years or with concurrent anticoagulant use was correlated with increased risk of ICH., Conclusion: In this large cohort study of middle-aged and older adults without stroke or TIA events, there was no significant association between aspirin use and ICH risk in the real-world setting. However, it is possible that aspirin use in those aged over 65 years and concurrent anticoagulant treatment may increase the risk of ICH., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: The Cardiometabolic Index (CMI) is a novel marker of visceral obesity and dyslipidemia. Our study aimed to explore the association between CMI and kidney stones among US adults., Methods: This cross-sectional study was conducted among adults with complete records of CMI and kidney stones information from the 2011 to 2018 National Health and Nutrition Examination Survey (NHANES). Inverse probability treatment weighting (IPTW) was used to balance the baseline characteristics of the study population. The independent relationship between CMI and kidney stones was evaluated using IPTW-adjusted multivariate logistic regression, restricted cubic splines (RCS), and subgroup analysis., Results: A total of 9,177 participants, with an average CMI of 0.72 (0.99), were included in this study. The IPTW-adjusted logistic regression revealed that CMI was an independent risk factor for kidney stones. The adjusted odds ratio (OR) for kidney stones were 1.39 (95% CI: 1.24 - 1.56, P < 0.001) for the second CMI tertile and 1.31 (95% CI: 1.17 - 1.47, P < 0.001) for the third CMI tertile, compared with the first CMI tertile. A linear relationship between CMI levels and kidney stone risk was observed in the RCS analysis. Subgroup analysis showed that the association between CMI levels and kidney stone risk remained stable across groups., Conclusions: A positive association between CMI level and the risk of kidney stones was observed among US adults in our study. Further large-scale prospective studies are needed to validate our findings., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Wang, Wang, Tang, Liu, Pan and Zhong.)

Objective: To examine the development and persistence of multiple physical symptoms (MPS) over a decade including the associations with sociodemographics and coping strategies., Method: A longitudinal study of 16,405 individuals aged 20-64 years participating in the Danish Symptom Cohort (DaSC) was conducted in 2012 with follow-up data in 2022 (DaSC II). MPS were assessed according to the unifying diagnostic construct of bodily distress syndrome, and coping was measured with the Brief Approach/Avoidance Coping Questionnaire. Descriptive statistics and multivariable logistic regression analyses were performed., Results: Among individuals not having MPS in 2012, 17 % had developed MPS in 2022. Among individuals having MPS in 2012, 57 % had persistence of MPS in 2022. Individuals who developed or had persistence of MPS at follow-up were more likely to be female, have lower educational level, be immigrant, redeem antidepressants, have lower approach scores as well as higher diversion and resignation scores., Conclusions: Individuals responding to stressful situations with low approach, high diversion, and high resignation may be at higher risk of developing MPS and have persistence of MPS. As coping can be targeted through psychotherapy, it is important to focus on maladaptive strategies, especially in high-risk groups for developing and maintaining MPS., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Most previous studies found an elevated risk of endometrial cancer among women with polycystic ovary syndrome (PCOS). However, these had highly varying methods for ascertainment of PCOS diagnoses and limitations such as few exposed women and short follow-up. In this cohort study, we investigated the association between PCOS and endometrial cancer among women born in Denmark between January 1, 1940, and December 31, 1993 (n = 1 719 121). Data in this study, including PCOS and endometrial cancer diagnoses and covariates, were derived from nationwide registers. We used Cox proportional hazards regression models to calculate hazard ratios (HRs) and 95% CIs. A total of 7862 endometrial cancer cases were identified during 23.7 years of follow-up (IQR, 37.7-61.9). We found an increased risk of endometrial cancer among women with PCOS compared with women without PCOS (HR = 3.02; 95% CI, 2.03-4.49). The risk was increased for premenopausal women (HR = 5.82; 95% CI, 3.64-9.30), whereas no marked association was seen for postmenopausal women. However, for postmenopausal women, results were limited by few cases and young age at the end of follow-up. Mounting evidence of an increased risk for endometrial cancer among women with PCOS reinforces the need for prevention and early detection.

Background: Ankylosing Spondylitis (AS) is a systemic chronic rheumatic disease characterized by involvement of the axial skeletal and sacroiliac joints. Although this disease is not rare amongst women of reproductive age, data regarding pregnancy outcomes have demonstrated conflicting results. We therefore aimed to compare pregnancy and perinatal outcomes between women who suffered from AS to those who did not., Methods: A retrospective cohort study using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS). Included in the study were all pregnant women who delivered or had a maternal death in the US between 2004 and 2014. Women with an ICD-9 diagnosis of AS before or during pregnancy were compared to those without. Pregnancy, delivery, and neonatal outcomes were compared between the two groups using multivariate logistic regression models adjusting for potential confounders., Results: A total of 9,096,788 women were inclusion in the analysis. Amongst them, 383 women (3.8/100,000) had a diagnosis of AS and the rest were controls. Women with AS, compared to those without, were more likely to be older; Caucasian; from higher income quartiles; suffer from thyroid disorders, and have multiple pregnancies (p < 0.001, all). After adjusting for confounders, patients in the AS group, compared to those without, had a higher rate of cesarean delivery (CD) (aOR 1.47, 95% CI 1.14-1.91, p = 0.003); gestational diabetes (aOR 1.55, 95% CI 1.02-2.33, p = 0.038); and placenta previa (aOR 3.6, 95% CI 1.6-8.12, p = 0.002). Regarding neonatal outcomes, patients with AS, compared to those without, had a higher rate of small-for-gestational-age (SGA) neonates (aOR 2.19, 95% CI 1.22-3.93, p = 0.009); and intrauterine fetal death (IUFD) (aOR 3.46, 95% CI 1.11-10.83, p = 0.033)., Conclusion: Women diagnosed with AS have an increased risk of obstetric complications, including CD, as well as an increased risk of SGA and IUFD., (© 2024.

Objective: To explore the association between representative insulin resistance (IR) indices and the risk of kidney stone disease in an American adult population. The representative IR indices referred to metabolic score for IR (METS-IR), triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, triglyceride glucose-body mass index (TyG-BMI), visceral adiposity index (VAI), and homeostatic model assessment of IR (HOMA-IR)., Methods: We investigated adult participants who joined the 2015-2018 National Health and Nutrition Examination Survey (NHANES) and reported kidney stone histories. Weighted proportions, multivariable regression analysis, and restricted cubic splines were used to evaluate the associations between IR indices and kidney stones after their adjustment for gender, age, race, education, smoking status, alcohol drinking frequency, hypertension and diabetes status, physical activity level, water intake, and levels of calcium, cholesterol, and uric acid., Results: A total of 19,225 participants were included. The weighted prevalence of kidney stone was 11.1%. A multivariable logistic regression model showed a dose-response relationship between the METS-IR and kidney stone [odds ratio (OR) = 1.02, 95% confidence interval (CI) (1.01, 1.04), p < 0.01]. A similar relationship was observed between the TyG-BMI and kidney stone after full adjustment [OR = 1.0, 95% CI (1.0, 1.01), p < 0.001]. Sex-stratified analyses revealed that the association between METS-IR and nephrolithiasis [OR = 1.03, 95% CI (1.01, 1.05), p < 0.01], and the association between TyG-BMI and nephrolithiasis [OR = 1.01, 95% CI (1.0, 1.01), p <0.001] was significant among the male participants in the fully adjusted model. Moreover, a significant association was found between the METS-IR levels and nephrolithiasis [OR = 1.03, 95% CI (1.01, 1.06), p < 0.01], and between the TyG-BMI levels and nephrolithiasis [OR = 1.01, 95% CI (1.0, 1.01), p < 0.05] among the diabetic participants after full adjustment. Furthermore, a potential nonlinear association was found between other IR indices (i.e., TG/HDL-C, VAI, and HOMA-IR) and the risk of kidney stone disease., Conclusion: Higher METS-IR and TyG-BMI levels were associated with a higher risk of nephrolithiasis. Future investigations are required to identify the role of IR in the progress of kidney stone formation and to propose prevention measures and health guidelines., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Shen, Zhu, Bi, Shen, Shen, Deng, He, Wang and Ding.)

Background: Cognitive reserve (CR) may be beneficial to the physical function of the elderly., Objective: We aimed to examine the association of CR proxies and composite CR capacity with physical function in older adults while considering age and sex., Methods: This population-based cross-sectional study included 4,714 participants living in rural China (age≥60 years) who were dementia-free. Structural equation modeling was used to generate a composite CR score by integrating early-life education, midlife occupational complexity, and late-life mental activity and social support. The Short Physical Performance Battery (SPPB) measured physical function. Data were analyzed using linear regression models., Results: Greater educational attainment and mental activity were associated with higher composite SPPB scores and those of its three subtests ( p  < 0.05). Skilled occupations were associated with higher SPPB, chair stand, and walking speed scores, while greater social support was associated with higher scores for SPPB and chair stand ( p  < 0.05). Each 1-point increase in composite CR score (range: -0.77 to 1.03) was linearly associated with a multivariable-adjusted β-coefficient of 0.74 (95% confidence interval (CI): 0.58-0.89) for total SPPB score, 0.16 (0.10-0.22) for balance test, 0.40 (0.32-0.48) for chair stand, and 0.17 (0.12-0.23) for walking speed. The association between higher composite CR and total SPPB scores was more prominent in those≥75 years than those aged 60-74 years ( p  < 0.01). There was no statistical interaction of composite CR score and sex in physical function., Conclusions: High CR is associated with better physical function, especially among older adults (≥75 years)., Competing Interests: The authors have no conflict of interest to report., (© 2024 – The authors.

Introduction: CD33 rs3865444 and hypertension (HTN) are related to cognitive impairment, individually. However, little is known about their combined effects on cognitive function in older adults., Methods: This population-based study included 4368 dementia-free participants (age ≥65 years) in the Multimodal Interventions to Delay Dementia and Disability in Rural China (MIND-China), with data available in 1044 persons for gray matter volume and 85 persons for cerebral blood flow (CBF). We used general linear regression and mediation models to examine the associations of rs3865444 and HTN with cognition, brain atrophy, and CBF., Results: Among rs3865444 CC carriers, HTN and late-life HTN were significantly associated with impaired cognition. Midlife and late-life HTN were correlated with brain atrophy. CD33 rs3865444 CC moderated the mediation effect of gray matter volume on the association between HTN and global cognition. HTN was correlated with low CBF in rs3865444 CC carriers., Discussion: There are synergistic associations of CD33 rs3865444 and HTN with brain and cognitive aging in dementia-free older adults., (© 2024 The Author(s).

Introduction: The histological transformation (HT) of follicular lymphoma (FL) is a crucial biological event. The study aimed to evaluate the incidence, clinicial characteristics, prognosis and impact of HT time on survival of FL transforming to diffuse large B-cell lymphoma in population-based large-scale cohorts., Methods: A retrospective cohort study of FL with HT was performed in the Surveillance, Epidemiology, and End Results database. The Hematological Malignancy Research Network FL cohort and Aristotle study FL cohort were used to assess the external validity., Results: Among 44,127 FL cases from the Surveillance, Epidemiology, and End Results database, 1311 cases were pathology-proven recorded to transform to diffuse large B-cell lymphoma. The cumulative rates of HT at 5, 10, and 15 years after FL diagnosis were estimated to be 1.19%, 2.93%, and 5.01%, respectively. Significantly worse overall survival and cancer-specific survival were exhibited in patients with HT than those without HT. Early HT (transformation of FL within 48 months after FL diagnosis [TOD48]) was an independent predictor for adverse overall survival of HT patients, regardless of treatment modalities before transformation. The adverse prognostic effect of TOD48 was validated in the Hematological Malignancy Research Network cohort and Aristotle study cohort. Older age (>75 years) and B symptoms within FL at diagnosis were the independent risk factors of TOD48. Furthermore, a novel prognostic model combining TOD48 with Follicular Lymphoma International Prognostic Index (TOD48-FLIPI) was constructed and validated for risk stratification., Conclusion: TOD48 was a risk indicator of HT, and the novel prognostic model "TOD48-FLIPI" for HT patients was proposed., (© 2024 American Cancer Society.)

Introduction: Randomized controlled trials (RCT) have not demonstrated a role for continuous positive airway pressure (CPAP) on the secondary prevention of major cardiovascular events in obstructive sleep apnea (OSA) patients. However, participants in RCTs are substantially different from real-world patients. Therefore, we aimed to assess the effect of CPAP treatment on major cardiovascular events in real-world OSA patients., Methods: Population-based longitudinal observational study including all OSA patients with an active CPAP prescription at the beginning of 2011 in Catalonia, Spain, that terminated CPAP treatment during 2011 and did not have CPAP prescriptions between 2012-2015; and propensity-score-matched OSA patients that continued CPAP treatment until the end of 2015 or death. Adjusted hazard ratios were used to assess the association between CPAP treatment and overall and cardiovascular mortality, cardiovascular hospitalizations, or major adverse cardiovascular events (MACEs)., Results: 3638 CPAP terminators and 10,914 propensity-score-matched continuators were included (median age 67 [57-77] years, 71.4% male). During a median follow-up of 47.9 months CPAP continuators showed a lower risk of cardiovascular death than terminators (hazard ratio [HR]: 0.61; 95% confidence interval [CI]: 0.50-0.75) after adjusting by age, sex and key comorbidities. Similar results were found for cardiovascular hospitalizations (HR: 0.87; 95% CI: 0.76-0.99) and MACEs (HR: 0.84; 95% CI: 0.75-0.95)., Conclusion: CPAP treatment continuation could be associated with a significantly lower risk of major cardiovascular events in real-world OSA patients. This result highlights the importance of including real-world patients in studies on OSA., (Copyright © 2024 SEPAR. Published by Elsevier España, S.L.U. All rights reserved.)

Histological transformation into an aggressive B-cell lymphoma indicates a poor survival outcome for patients with indolent marginal zone lymphoma (MZL), which has been less studied. Large-scale data with long-term follow-up to investigate MZL transformation is limited. Here, by reporting a US-Nationwide cohort of 30,619 MZL patients diagnosed between 2000 and 2019, we found that transformation occurred in 2.08% (N = 624) of MZL cases, with the transformation incidence of 3.1 per 1,000 person-years. Advanced Ann Arbor stage, nodal MZL (NMZL) and splenic MZL (SMZL) were associated with an elevated risk of transformation. Certain subtype-specific characteristics, such as non-gastric extra-nodal MZL (vs. gastric, HR, 1.51, 95%CI 1.13-2.04; p = 0.006), and receiving splenectomy for SMZL (HR, 2.04, 95%CI 1.28-3.26; p = 0.003), also indicated a higher risk of transformation. Besides, transformation independently increased the overall mortality risk (HR, 1.38, 95%CI 1.24-1.53, p < 0.001), especially the higher lymphoma-caused mortality risk (HR, 3.21, 95%CI 2.81-3.67, p < 0.001). Transformation was also associated with a higher percentage of lymphoma-caused deaths. The post-transformation prognostic analyses demonstrated that female gender and age ≥ 65 years independently affected patients' mortalities. These findings, based on the largest cohort to date, contribute to a better understanding of transformed MZL, and provide valuable reference points for guidelines and patient counseling., (© 2024.

Objectives: Bacteremia with anaerobic bacteria is generally a marker of severe prognosis. However, population-based data is lacking. Our aim was to describe the epidemiology and the 30-day mortality rate of anaerobic bacteremia in a Danish population-based setting., Methods: In this population-based cohort study, all first-time episodes of anaerobic bacteremia from the North Denmark Bacteremia Research Database during 1994-2019 were identified. Information on comorbidities, discharge diagnoses, and mortality was retrieved. 30-day mortality rates were calculated and a multivariate logistic regression analysis to identify risk factors for death was performed., Results: 1750 episodes with anaerobic bacteremia were identified, corresponding to an incidence rate of 12.5 per 100,000 inhabitants (increasing from 11.2 in 1994-2014 to 17.7 in 2015-2019). Of these episodes, a third were polymicrobial, and the majority (70 %) of patients had one or more comorbid conditions. Abdominal infection was the source of bacteremia in 61 % of patients, while it was unknown for 15 %. The most frequently isolated genera were Bacteroides (45 %), Clostridium (20 %) and Fusobacterium (6 %). The overall crude 30-day mortality rate was 27 %, but rates were even higher for patients of high age, with liver disease, and solid tumors. The odds ratio (OR) for 30-day mortality was 1.32 for Clostridium species, and 1.27 for polymicrobial bacteremia with aerobic bacteria., Conclusions: The incidence rate of anaerobic bacteremia increased, and the 30-day mortality rate remained high during the study period. Multiple factors influence 30-day mortality rates, including high age, liver disease, solid tumor, polymicrobial bacteremia, and bacteremia with Clostridium species., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Background: We sought to examine the associations of the Lifestyle for Brain Health (LIBRA) index with cognitive function among rural Chinese older adults and to explore the potential role of cluster of differentiation 33 gene (CD33) in the associations., Methods: This population-based cross-sectional study included 4914 dementia-free participants (age ≥60 years; 56.43 % women) in the 2018 baseline examination of MIND-China. The LIBRA index was generated from 11 factors. We used a neuropsychological test battery to assess episodic memory, verbal fluency, attention, executive function, and global cognition. The CD33(rs3865444) polymorphism was detected using multiple-polymerase chain reaction amplification. Data were analyzed using the general linear regression models., Results: A higher LIBRA index was associated with multivariable-adjusted β-coefficient (95 %CI) of -0.011(-0.020- -0.001) for global cognitive z-score, -0.020(-0.033- -0.006) for episodic memory, and -0.016(-0.029- -0.004) for verbal fluency. The CD33(rs3865444) was associated with a lower global cognitive z-score in the additive (CA vs. CC: β-coefficient=0.042; 95 %CI=0.008-0.077), the dominant (CA+AA vs. CC: 0.040; 0.007-0.073), and the over-dominant (CA vs. CC+AA: 0.043; 0.009-0.077) models. Similar results were obtained for verbal fluency and attention. The CD33 gene showed statistical interactions with LIBRA index on cognitive function (P interaction <0.05) such that a higher LIBRA index was significantly associated with lower z-scores of global cognition and attention only among CD33 CC carriers (P < 0.05)., Conclusions: This population-based study reveals for the first time that a higher LIBRA index is associated with worse cognitive performance in rural Chinese older adults and that CD33 gene could modify the association., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier B.V.

Introduction: We examined the associations of polygenic risk score (PRS) with Alzheimer's disease (AD) and plasma biomarkers in the Chinese population., Methods: This population-based study used baseline data from MIND-China (2018; n = 4873) and follow-up data from dementia-free individuals (2014-2018; n = 2117). We measured AD-related plasma biomarkers in a subsample (n = 1256). Data were analyzed using logistic and Cox regression models., Results: We developed PRS with (PRS APOE ) and without (PRS non- APOE ) apolipoprotein E (APOE) gene. In the longitudinal analysis, PRS APOE was associated with a multivariable-adjusted hazards ratio of 1.91 (95% CI = 1.13-3.23) for AD. PRS APOE in combination with demographics yielded discriminative (area under the curve [AUC]) and predictive(C-statistic) accuracy of 0.80 (95% confidence interval [CI] = 0.77-0.84) and 0.80 (0.77-0.82), respectively. PRS non- APOE showed an association with AD risk similar to PRS APOE . PRS APOE , but not PRS non- APOE , was associated with reduced plasma Aβ42/Aβ40 ratio and increased Neurofilament light chain (NfL) (p < 0.05)., Discussion: The PRS with and without APOE gene, in combination with demographics, shows good discriminative and predictive ability for AD. The AD-related pathologies underlie AD risk associated with PRS APOE ., Highlights: The PRS APOE and PRS non- APOE were associated with AD risk in the Chinese population. The PRS APOE and PRS non- APOE , in combination with demographics, showed good discriminative and predictive ability for AD. The AD-related pathologies underlie the AD risk associated with PRS APOE but not PRS non- APOE ., (© 2024 The Author(s).

Background and Purpose: Several studies have reported substantial comorbidity between epilepsy and migraine. Most of these were based on clinical cohorts or used unvalidated diagnostic instruments. Our study re-examined this association in a large general population cohort using validated diagnoses for both disorders., Methods: A total of 65,407 participants (≥20 years old) from HUNT (the Trøndelag Health Study) were classified for migraine and nonmigraine headache using a validated questionnaire. Medical record review was used to validate and classify epilepsy in 364 participants (cases), who were compared with 63,298 participants without epilepsy (controls). The association between epilepsy and migraine was analysed using logistic regression adjusted for sex and age., Results: Patients with epilepsy had no increased prevalence of migraine (odds ratio [OR] = 0.95, 95% confidence interval [CI] = 0.68-1.33) or nonmigraine headache (OR = 1.18, 95% CI = 0.93-1.50) compared to controls. When stratified by headache frequency, epilepsy was associated with a higher prevalence of migraine with highly frequent headache (≥7 days/month; OR = 1.73, 95% CI = 1.08-2.78)., Conclusions: Migraine was equally common in people with and without epilepsy. Patients with epilepsy who suffered from migraine were more prone to having highly frequent migraine., (© 2024 The Author(s).

Background and Purpose: Emerging evidence has linked impaired kidney function with dementia in older adults, but the neuropathological pathways underlying their association remain poorly understood. We sought to examine the relationships of kidney function with dementia and plasma biomarkers in a Chinese rural population., Methods: This population-based study used data from the baseline examination of the Multimodal Interventions to Delay Dementia and Disability in rural China (MIND-China) cohort (March-September 2018; n = 5715). Kidney function was assessed using estimated glomerular filtration rate (eGFR) based on serum creatinine level. Dementia, Alzheimer's disease (AD) and vascular dementia (VaD) were diagnosed according to the international criteria. Plasma biomarkers were measured using the SIMOA platform in a subsample (n = 1446). Data were analyzed using logistic, general linear, and mediation models., Results: Of the 5715 participants, 306 were diagnosed with dementia, including 195 with AD and 100 with VaD. Impaired kidney function (eGFR <60 vs. ≥90 mL/min/1.73 m 2 ) was associated with multivariable-adjusted odds ratios of 2.24 (95% confidence interval [CI] 1.44-3.46) for all-cause dementia, 1.85 (1.07-3.18) for AD, and 2.49 (1.16-5.22) for VaD. In the biomarker subsample, impaired kidney function was significantly associated with higher plasma amyloid-β (Aβ)40 (β-coefficient = 54.36, 95% CI 43.34-65.39), Aβ42 (β-coefficient = 3.14, 95% CI 2.42-3.86), neurofilament light chain (β-coefficient = 10.62, 95% CI 5.62-15.62), and total tau (β-coefficient = 0.68, 95% CI 0.44-0.91), and a lower Aβ42/Aβ40 ratio (β-coefficient = -4.11, 95% CI -8.08 to -0.14). The mediation analysis showed that plasma total tau significantly mediated 21.76% of the association between impaired kidney function and AD (p < 0.05)., Conclusion: Impaired kidney function is associated with dementia and plasma biomarkers among rural-dwelling older Chinese adults, and the association with AD is partly mediated by plasma biomarkers for neurodegeneration., (© 2024 The Author(s).

Background: Cardiovascular disease (CVD) risk factors tend to cluster and interact multiplicatively and have been incorporated into risk equations such as the Framingham risk score, which can reasonably predict CVD over short- and long-term periods. Beyond risk factor levels at a single time point, recent evidence demonstrated that risk trajectories are differentially related to CVD risk. However, factors associated with suboptimal control or unstable CVD risk trajectories are not yet established., Objective: This study aims to examine factors associated with CVD risk trajectories in a semirural, multiethnic community-dwelling population., Methods: Data on demographic, socioeconomic, lifestyle, mental health, and cardiovascular factors were measured at baseline (2013) and during follow-up (2018) of the South East Asia Community Observatory cohort. The 10-year CVD risk change transition was computed. The trajectory patterns identified were improved; remained unchanged in low, moderate, or high CVD risk clusters; and worsened CVD risk trajectories. Multivariable regression analyses were used to examine the association between risk factors and changes in Framingham risk score and predicted CVD risk trajectory patterns with adjustments for concurrent risk factors., Results: Of the 6599 multiethnic community-dwelling individuals (n=3954, 59.92% female participants and n=2645, 40.08% male participants; mean age 55.3, SD 10.6 years), CVD risk increased over time in 33.37% (n=2202) of the sample population, while 24.38% (n=1609 remained in the high-risk trajectory pattern, which was reflected by the increased prevalence of all major CVD risk factors over the 5-year follow-up. Meanwhile, sex-specific prevalence data indicate that 21.44% (n=567) of male and 41.35% (n=1635) of female participants experienced an increase in CVD risk. However, a stark sex difference was observed in those remaining in the high CVD risk cluster, with 45.1% (n=1193) male participants and 10.52% (n=416) female participants. Regarding specific CVD risk factors, male participants exhibited a higher percentage increase in the prevalence of hypertension, antihypertensive medication use, smoking, and obesity, while female participants showed a higher prevalence of diabetes. Further regression analyses identified that Malay compared to Chinese (P<.001) and Indian (P=.04) ethnicity, nonmarried status (P<.001), full-time employment (P<.001), and depressive symptoms (P=.04) were all significantly associated with increased CVD risk scores. In addition, lower educational levels and frequently having meals from outside were significantly associated to higher odds of both worsening and remaining in high CVD risk trajectories., Conclusions: Sociodemographics and mental health were found to be differently associated with CVD risk trajectories, warranting future research to disentangle the role of psychosocial disparities in CVD. Our findings carry public health implications, suggesting that the rise in major risk factors along with psychosocial disparities could potentially elevate CVD risk among individuals in underserved settings. More prevention efforts that continuously monitor CVD risk and consider changes in risk factors among vulnerable populations should be emphasized., (©Hamimatunnisa Johar, Chiew Way Ang, Roshidi Ismail, Zaid Kassim, Tin Tin Su.

Background: Patients with ankylosing spondylitis (AS) suffer from impaired physical activity and are prone to motor vehicle accidents (MVA), but definite instruction regarding the relationship between disease evolvement and MVA and potential risk factors is lacking., Objectives: To explore the risk factors and their impact on recorded MVA with profound injuries in AS patients with prescriptions., Design: Nationwide, population-based, matched retrospective cohort study., Methods: Using Taiwanese administrative healthcare databases, with available claims data from 2003 to 2013, we selected 30,911 newly diagnosed adult AS patients with concurrent prescriptions from 2006 to 2012 as AS patients, along with 309,110 non-AS individuals as the control group, matched in gender, age at index date and year of the index date. The risk of recorded MVA with profound injuries was compared between the two groups in terms of incidence rate ratio (IRR) and log-rank test p -value. Using Cox regression analysis, we studied associations between the risk and AS diagnosis., Results: The risk of recorded MVA with profound injuries in AS patients was significantly higher than in non-AS individuals, specifically 2 years after AS diagnosis (IRR, 2.00; 95% confidence interval (CI), 1.42-2.81). For patients with follow-up periods >2 years, the adjusted risk was positively associated with suburban residence (adjusted hazard ratio (aHR), 2.18; 95% CI, 1.55-3.06), rural residence (aHR, 1.89; 95% CI, 1.27-2.80), lower insured income (aHR, 1.35; 95% CI, 1.01-1.81) and recorded MVA with profound injuries before AS diagnosis (aHR, 6.16; 95% CI, 2.53-14.96). AS diagnosis (aHR, 1.81; 95% CI, 1.27-2.59) and frequency of ambulatory visits (aHR, 1.01; 95% CI, 1.004--1.02) were specific associated factors for them compared with those with follow-up periods ⩽2 years., Conclusion: For adult AS patients in Taiwan, factors such as AS disease evolution and frequent ambulatory visits for disease control in the second year of the disease course may significantly increase the risk of recorded MVA with profound injuries beyond 2 years after AS diagnosis., Competing Interests: The authors declare that there is no conflict of interest., (© The Author(s), 2024.)

Background: Depression presents significant challenges to mental health care. Although physical activity is highly beneficial to mental and physical health, relatively few studies have conducted on the relationship between them., Aim: To investigate the association between muscle quality index (MQI) and incidence of depression., Methods: The data used in this cross-sectional study were obtained from the 2011-2014 National Health and Nutritional Examination Survey, which included information on MQI, depression, and confounding factors. Multivariable logistic regression models were employed, while taking into account the complex multi-stage sampling design. A restricted cubic spline model was utilized to investigate the non-linear relationship between the MQI and depression. Additionally, subgroup analyses were performed to identify influential factors., Results: The prevalence of depression in this population was 8.44%. With the adjusted model, the MQI was associated with depression in females (odds ratio = 0.68, 95% confidence interval: 0.49-0.95) but not in males (odds ratio = 1.08, 95% confidence interval: 0.77-1.52). Restricted cubic spline adjustment of all covariates showed a significant negative non-linear relationship between depression and the MQI in females. The observed trend indicated an 80% decrease in the risk of depression for each unit increase in MQI, until a value of 2.2. Subsequently, when the MQI exceeded 2.2, the prevalence of depression increased by 20% for every unit increase in the MQI. Subgroup analyses further confirmed that the MQI was negatively associated with depression., Conclusion: The MQI was inversely correlated with depression in females but not males, suggesting that females with a higher MQI might decrease the risk of depression., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2024.

Purpose: To assess the prevalence of age-related macular degeneration (AMD) and reticular pseudodrusen (RPD) in very old individuals., Methods: The population-based Ural Very Old Study consisted of 1526 (81.1%) out of 1882 eligible individuals aged 85 + years. All individuals living in the study regions and having an age of 85 + years were eligible for the study. The presence of AMD and RPDs was assessed on color fundus photographs, red-free fundus images, and optical coherence tomographic images., Results: The study included 932 (61.1% of 1526) individuals (age:88.6 ± 2.7 years) with available fundus images. Prevalence of any, early, intermediate and late AMD was 439/932 (47.1%; 95%CI:44.0,50.0), 126/932 (13.5%; 95% CI:11.0,16.0), 185/932 (19.8%; 95% CI:17.3,22.3) and 128/932 (13.7%; 95% CI:11.7,15.7), respectively. Neovascular AMD was present in 63 eyes (6.8%;95%CI:5.3,8.3) and geographic atrophy in 65 eyes (7.0%;95%CI:5.0,9.0). Higher prevalence of any AMD and late AMD was significantly correlated with urban region of habitation (OR:3.34; 95% CI:2.37,4.71; P < 0.001), and with older age (OR:1.12; 95% CI:1.04,1.19; P = 0.001), female sex (OR:1.63; 95%CI:1.02,2.60; P = 0.04), and urban region of habitation (OR:2.89; 95% CI:1.59,5.26; P < 0.001), respectively. RPDs (assessed in 889 (58.3%) study participants) were present in 220/889 participants (24.7%; 95%CI:21.7,27.7). Higher RPD prevalence was associated (multivariable analysis) with higher serum concentration of the rheumatoid factor (OR:1.15; 95% CI:1.04,1.28; P = 0.008), shorter axial length (OR:0.84;95%CI:0.71,0.00;P = 0.04), and higher degree of nuclear cataract (OR:1.06; 95% CI:1.01,1.12; P = 0.02). AMD was the main cause for vision impairment in 230 (24.7%) participants, for moderate-to-severe vision impairment in 75 (8.0%; 95% CI: 6.4, 10.0) individuals, and for blindness in 15 (1.6%; 95%CI: 0.8, 2.5) persons respectively., Conclusions: In this ethnically mixed, very old population, AMD prevalence (any AMD:47.1%;late AMD:13.7%) was statistically independent of most systemic and ocular parameters. Higher RPD prevalence correlated with shorter axial length., Key Messages: What is known The prevalence of age-related macular degeneration (AMD) has been explored in many studies and societies. Information is missing about its prevalence and associations in very old individuals. The same holds true for reticular pseudodrusen of the macula. What is new In an ethnically mixed, very old population in Bashkortostan / Russia, the prevalence of AMD (any AMD: 47.1%; late AMD:13.7%) was statistically independent of most systemic and ocular parameters. Higher prevalence of reticular pseudodrusen correlated with shorter axial length., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Objectives: The enormous societal and individual consequences of mental health disorders and detrimental health behaviours in the general population are of paramount concern. Many argue that 'prevention is the best cure', pushing for the implementation of early (preventive) interventions. Key questions regarding early interventions include which population segment to target for screenings and what information these screenings should focus on. In line with previous efforts, this study aimed to identify which population segment holds the majority (≥ 80 %) of different economically costly outcomes in society, and whether child abuse before the age of 16 years predicts being part of that population segment., Study Design: Epidemiological cohort study., Methods: This study used the Netherlands Mental Health Survey and Incidence Study-2, a Dutch epidemiological cohort study including 6646 adults aged 18-64 years at baseline, spanning four timepoints from 2007 to 2018. Cumulative distributions were computed to identify high-cost population segments of economically costly outcomes in adulthood (i.e., mental and physical health [behaviours], unemployment and work absenteeism). Child abuse was examined as a potential predictor of these segments and the risk of multiple high-cost population segment membership was investigated by conducting Poisson regressions., Results: A 20 % population segment carried between 42 % and 100 % of economically costly outcomes. Being exposed to more child abuse predicted being in a high-cost population segment, albeit with small effect sizes. Being exposed to more child abuse also predicted belonging to multiple high-cost population segments across different economically costly outcomes., Conclusions: The study findings have implications for policy makers. Emphasis should be placed on prevention aimed at identifying potential members of multiple high-cost population segments., (Copyright © 2024 The Authors. Published by Elsevier Ltd..

Objective: The systemic immunity-inflammation index (SII) is a newly developed biomarker that provides an integrated measure of inflammation in the body. We aim to evaluate the relationship between SII and body fat distribution., Methods: Adults from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 were included. The SII was computed using lymphocyte (LC), neutrophil (NC), and platelet (PC) counts as its components. Body fat distribution was assessed by (total, android, gynoid) percentage fat, total abdominal fat area, subcutaneous adipose tissue area, visceral adipose tissue area, and the ratio of visceral to subcutaneous adipose tissue area (V/S ratio). Multivariable weighted linear regression and subgroup analysis were use to examine the relationships between fat distribution and SII. Restricted cubic splines (RCS) and threshold effect analysis were used to examine analyze nonlinear associations., Results: After exclusions, a total of 11,192 adults with a weighted mean age of 38.46 ± 0.26 years were studied. In multivariable weighted linear regression, each level increase in log 2 SII was associated with increased of 0.23 SDs total percentage fat (95% CI = 0.03, 0.43) and 0.26 SDs android percentage fat (95% CI = 0.06, 0.47). Besides, the subgroup analysis showed that the positive association between SII and android percentage fat was mainly among obese individuals (BMI > 30 kg/m 2 ) and non-obese individuals without DM or hypertension. Meanwhile, the relationship between SII and the V/S ratio was found to be significant in the female subgroup, the obese subgroup, individuals with non-alcoholic fatty liver disease (NAFLD), and those without diabetes mellitus. Finally, SII exhibited an inverted U-shaped relationship with total percentage fat, android percent fat and total abdominal fat. Accordingly, threshold effect analysis indicated a positive association between lower SII levels and total percentage fat, android percentage fat and total abdominal fat area., Conclusions: In the nationwide study, it was observed that the SII exhibited a significant correlation with higher levels of body fat, specifically android fat. This association was particularly noticeable within specific subgroups of the population., (© 2024. The Author(s).)

Fibroblast growth factor 21 (FGF21) is a liver-secreted hormone involved in the regulation of lipid, glucose, and energy metabolism. Its serum concentration increases with age but also is higher in numerous diseases. FGF21 is being investigated for biomarker properties and as a potential therapeutic target. The present study aimed to assess the prognostic value of FGF21 in an older population-based cohort, the PolSenior2 study participants. In the sub-analysis of 3512 individuals, aged 60 and older, stratified according to FGF21 into tertiles, the survival estimate was worse in participants with middle and high levels compared to the lowest tertile. These results were consistent with univariable Cox regression analysis, in which participants in the middle and the high FGF21 tertiles after adjustment for age had 1.43-fold (HR, 1.31; 95% CI, 1.05 - 1.62) and 2.56-fold (HR, 1.94; 95% CI, 1.59 - 2.37) higher risk for mortality, respectively, compared with those in the lowest tertile. In multivariable Cox regression analysis, the highest levels of FGF21 were associated with increased mortality (HR 1.53; 95% CI, 1.22 - 1.92) independently of co-morbidities and blood parameters. These results indicate that higher serum FGF21 concentration is an independent predictor of all-cause mortality in the general population of older adults.

Purpose: To delineate the current trends regarding gender-affirming surgeries (GAS) in Germany., Methods: Analysis of German hospital quality reports from 2006 to 2022 was conducted using the reimbursement.info tool. The German procedure classification (OPS) codes 5-646.0 for masculinizing- and 5-646.1 for feminizing surgery were assessed to identify GAS. Linear regression models were utilized for the analysis and depiction of current trends., Results: A total of 19,632 gender-affirming procedures were performed during the study period with an exponential increase over the years. Masculinizing surgeries increased from 246 in 2006 to 1291 cases in 2022 (increase by 424%; p < 0.001). The highest annual increase of 37.2% in numbers was from 2018 to 2019 (from 1235 to 1694 cases). Feminizing surgeries increased from 180 cases in 2006 to 799 procedures in 2022 (increase by 343%; p < 0.001). The cases increased most between 2015 and 2016 from 277 to 502 cases (81.2%). The number of hospitals offering these surgeries expanded from 24 in 2006 to 29 in 2022 (21% increase; p < 0.001)., Conclusion: This study demonstrates an exponential growth in numbers feminizing and masculinizing of GAS performed each year in Germany. Furthermore, a discernible trend emerges with a propensity for concentration of procedures within selected high-caseload centers across Germany., (© 2024 The Author(s).

Objectives: Current data on arterial and venous thrombotic events (ATE & VTE) and cardiovascular (CV) risk management in European systemic lupus erythematosus (SLE) population are limited. This study aimed to investigate the incidence and risk of thrombotic events and all-cause death in an Italian SLE cohort over the past decade, along with its pharmacotherapy., Methods: Incident SLE cases between 2010 and 2019 were identified using administrative health databases of the Lombardy Region. The association between SLE and outcomes, compared with age- and sex-matched controls, was reported as incidence rate per 1000 person-years and as adjusted hazard ratios with 95% confidence intervals., Results: Overall, 2133 SLE patients and 21 283 no-SLE individuals were included. A higher incidence rate of ATE (4.22 vs 2.26 1000 PY), VTE (1.85 vs 0.67 1000 PY,) and all-cause death (15.18 vs 6.22 1000 PY) was reported in SLE patients than in those without (p< 0.0001) as well as an increased risk of ATE (HR, 1.65; 95% CI, 1.20-2.26), VTE (HR, 2.25; 95% CI, 1.35-3.74), and all-cause death (HR, 1.81; 95% CI, 1.52-2.15). After SLE diagnoses, hydroxychloroquine and glucocorticoids were prescribed for at least 60% of patients. Additionally, a higher exposure to cardiovascular medications was also seen in SLE patients., Conclusion: Our findings confirmed higher risks of ATE, VTE and all-cause death in SLE patients. While increased CV medications use after SLE diagnoses suggests heightened awareness to CV risk profile, more attention is required to balance SLE disease activity with minimizing exposure to drugs associated with exacerbating CV risk., (© The Author(s) 2024.

Background and Objectives: Sarcomas developing in the visceral organs are extremely rare, with no previous reports to describe their national epidemiology. We analyzed Japanese domestic statistics for visceral sarcoma, using the National Cancer Registry (NCR) in Japan, a population-based database launched in 2016., Methods: We identified 3245 cases of visceral sarcomas in the NCR dated 2016-2019 to analyze demographic and disease information, initial diagnostic process, volume and type of the hospitals, treatment, and prognosis., Results: Visceral sarcoma shows a higher prevalence in the older generation (60+ years), with a significant male predominance (p = 0.006). Leiomyosarcomas occurred frequently in the gastrointestinal tract (N = 240; 39.5%), and angiosarcomas in the liver, gall bladder, pancreas, and spleen (N = 244; 43.9%). Visceral sarcomas were often treated in facilities of lower volume without specific adjuvant treatments (p < 0.001). The cumulative 3-year overall survival was 44.8%, and several factors such as surgery or absence of chemotherapy positively affected survival., Conclusions: This is the first nationwide study in Japan to analyze the inclusive epidemiology of visceral sarcomas. Visceral sarcomas are characterized by senior and male predominance with relatively poor prognosis, often managed in nonspecialized facilities and rarely with adjuvant therapies. Several histologic subtypes had the propensity to develop in specific organs., (© 2024 Wiley Periodicals LLC.)

Background: Previous studies indicate that vitamin C may decrease the occurrence and intensity of migraines, but the evidence is restricted due to small sample sizes. This study aimed to determine the magnitude of the association between dietary vitamin C intake and migraine in the general population., Methods: This cross-sectional study utilised data from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2004. Participants who had severe headaches or migraines in the past 3 months were classified as experiencing migraines. Dietary vitamin C intake was evaluated using the 24-h dietary recall system. Logistic regression models, restricted cubic spline (RCS) regression and stratified analyses were employed to assess the association between dietary vitamin C intake and migraine., Results: The study included 4101 participants, of whom 702 (17.12%) experienced migraine. The study revealed an inverse association between dietary vitamin C intake and migraine (odds ratio [OR] = 0.89, 95% confidence intervals [CI] = 0.83-0.96, p = 0.002) after adjusting for demographic covariates, lifestyle covariates, laboratory tests, physical examinations, physical activity, dietary covariates and comorbidities. When vitamin C intake was categorised, the adjusted OR (95% CI) for migraine in Q4 (highest vitamin C intake) was 0.64 (95% CI = 0.49-0.84, p = 0.001) compared to Q1 (lowest vitamin C intake). The RCS regression showed a linear inverse relationship between dietary vitamin C intake and migraine (p non-linearity  = 0.449). The findings remained consistent, and no significant interactions were found among different groups., Conclusions: Dietary vitamin C intake was inversely associated with migraine, and a linear negative relationship was found between vitamin C intake and migraine., (© 2024 The British Dietetic Association Ltd.)

Background: Systemic immune-inflammation index (SII) is a novel comprehensive inflammatory marker. Inflammation is associated with impaired lung function. We aimed to explore the possible relationship between SII and lung function to examine the potential of SII in predicting lung function decline., Methods: A cross-sectional survey was conducted using the data of the NHANES from 2007 to 2012. Multiple linear regression models were used to analyze the linear relationship between SII and pulmonary functions. Sensitivity analyses, subgroup analyses, and interaction tests were used to examine the robustness of this relationship across populations. Fitted smooth curves and threshold effect analysis were used to describe the nonlinear relationships., Results: A total of 10,125 patients were included in this study. After adjusting for all covariates, multiple linear regression model analysis showed that high Log2-SII level was significantly associated with decreased FVC(β, -23.4061; 95% CI, -42.2805- -4.5317), FEV1(β, -46.7730; 95% CI, -63.3371- -30.2089), FEV1%(β, -0.7923; 95% CI, -1.1635- -0.4211), FEV1/FVC(β, -0.6366; 95% CI, -0.8328- -0.4404) and PEF(β, -121.4468; 95% CI,-164.1939- -78.6998). The negative correlation between Log2-SII and pulmonary function indexes remained stable in trend test and stratified analysis. Inverted U-shaped relationships between Log2-SII and FVC, FEV1, FEV1%, and PEF were observed, while a negative linear correlation existed between FEV1/FVC and Log2-SII. The cutoff values of the nonlinear relationship between Log2-SII and FVC, FEV1, FEV1%, PEF were 8.3736, 8.0688, 8.3745, and 8.5255, respectively. When SII exceeded the critical value, the lung function decreased significantly., Conclusion: This study found a close correlation between SII and pulmonary function indicators. This study investigated the SII threshold when lung functions began to decline in the overall population. SII may become a promising serological indicator for predicting lung function decline. However, prospective studies were needed further to establish the causal relationship between these two factors., Competing Interests: The authors report no conflicts of interest in this work., (© 2024 Yuan et al.)

Although the survival rate of patients with childhood cancer has greatly improved, long-term survivors face specific problems such as the late effects of cancer treatment. In this study, we estimated the number of people who had experienced childhood cancer to predict their needs for medical care and social resources. Using data from the population-based Osaka Cancer Registry, we identified children aged 0-14 years who were diagnosed with cancer between 1975 and 2019. We estimated the prevalence on December 31, 2019, and the 5- and 10-year prevalence (i.e., the number of survivors living up to 5 or 10 years after the diagnosis of cancer) over time. The prevalence proportion was age-standardized using a direct standardization method. The prevalence estimates for Osaka were applied to the national population to determine the national prevalence in Japan. Among 8186 patients diagnosed with childhood cancer in Osaka, 5252 (987 per million) survived until December 31, 2019. The 5-year prevalence per million increased from 194 in 1979 to 417 in 2019 (+116%), while the 10-year prevalence increased from 391 in 1984 to 715 in 2019 (+83%). Based on the long-term registry data, an estimated 73,182 childhood cancer survivors were living in Japan by the end of 2019. The increasing 5-year and 10-year prevalence proportions indicate the continued need for cancer survivorship support for children, adolescents, and young adults. These estimates of the prevalence of childhood cancer survivors, including long-term survivors, may be useful for policymakers and clinicians to plan and evaluate survivorship care., (© 2024 The Authors.

Introduction: Evidence has emerged that cardiometabolic multimorbidity (CMM) is associated with dementia, but the underlying mechanisms are poorly understood., Methods: This population-based study included 5704 older adults. Of these, data were available in 1439 persons for plasma amyloid-β (Aβ), total tau, and neurofilament light chain (NfL) and in 1809 persons for serum cytokines. We defined CMM following two common definitions used in previous studies. Data were analyzed using general linear, logistic, and mediation models., Results: The presence of CMM was significantly associated with an increased likelihood of dementia, Alzheimer's disease (AD), and vascular dementia (VaD) (p < 0.05). CMM was significantly associated with increased plasma Aβ40, Aβ42, and NfL, whereas CMM that included visceral obesity was associated with increased serum cytokines. The mediation analysis suggested that plasma NfL significantly mediated the association of CMM with AD., Discussion: CMM is associated with dementia, AD, and VaD in older adults. The neurodegenerative pathway is involved in the association of CMM with AD., Highlights: The presence of CMM was associated with increased likelihoods of dementia, AD, and VaD in older adults. CMM was associated with increased AD-related plasma biomarkers and serum inflammatory cytokines. Neurodegenerative pathway was partly involved in the association of CMM with AD., (© 2024 The Author(s).

Literature on the association between ageism and falling among older adults is limited. Using data from the nationwide cross-sectional SABE ( Salud, Bienestar y Envejecimiento ) Colombia Survey in 2015 with 18,875 participants aged ≥60 years living in the communities, the study aims to evaluate the association between perceived ageism within the family, neighborhood, health services, and public services, and recurrent falling. Participants had a mean age of 69.2 ± 7.1; 56.1% were female. Recurrent falling prevalence was 15%, and experiencing any ageism was 10%. Multivariable logistic regression analyses showed higher odds of recurrent falling for any ageism (OR = 1.81, 95% CI 1.61-2.02, p < .0001). High depressive symptoms mediated 10.1% of the association between any ageism and recurrent falling, followed by low instrumental activities of daily living (9.7%) and multimorbidity (9.3%). Current findings open new areas of gerontological research by expanding the risk factors for falling among older adults to include ageism perceptions., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction and Objectives: Our aim was to describe the contemporary epidemiological profile of infective endocarditis (IE) in Spain, and to evaluate variations in IE incidence, characteristics, and outcomes among the different Spanish regions (autonomous communities [AC])., Methods: We conducted a retrospective, population-based study, using data obtained from national in-patient hospital activity of all patients discharged with a diagnosis of IE from hospitals included in the Spanish National Health System, from January 2016 to December 2019. Differences in the IE profile between the 17 Spanish AC were analyzed., Results: A total of 9008 hospitalization episodes were identified during the study period. Standardized incidence of IE was 5.77 (95%CI, 5.12-6.41) cases per 100 000 population. Regarding predisposing conditions, 26.8% of episodes occurred in prosthetic valve carriers, 36.8% had some kind of valve heart disease, and 10.6% had a cardiac implantable electronic device. Significant differences were found between AC in terms of incidence, predisposing conditions, and microbiological profile. Cardiac surgery was performed in 19.3% of episodes in the total cohort, and in 33.4% of the episodes treated in high-volume referral centers, with wide variations among AC. Overall in-hospital mortality was 27.2%. Risk-adjusted mortality rates also varied significantly among regions., Conclusions: We found wide heterogeneity among Spanish AC in terms of incidence rates and the clinical and microbiological characteristics of IE episodes. The proportion of patients undergoing surgery was low and in-hospital mortality rates were high, with wide differences among regions. The development of regional networks with referral centers for IE could facilitate early surgery and improve outcomes., (Copyright © 2024 Sociedad Española de Cardiología.

Chronic Obstructive Pulmonary Disease (COPD) is a complex and heterogeneous condition. Exposure to tobacco smoke and air pollutants are key risk factors for COPD development; however, other risk factors include race/ethnicity, sex of adults, a history of asthma, occupational exposures, and chronic respiratory infections. Data for the current study were from the 2022 Behavioral Risk Factor Surveillance Survey. Chi-squares and multinomial logistic regression analyses, adjusted with the survey's sampling weight, were used to examine how critical health indicators impacted a COPD diagnosis. Participants ( N = 311,175) were adults aged 45 years and older. Adjusted multinomial regression analyses showed adults who reported asthma, current and former smoking, poor physical health, depression, less physical activity, and fatigue were more likely to report COPD. Those with COPD were more likely to be male than female. Moreover, those with COPD reported higher rates of health insurance coverage, and yet had lower income and more financial difficulty affording a doctor for health services. In a follow up regression analysis, examining racial differences in COPD for participants, American Indian adults had a higher odds of reporting COPD than the "other" race groups. Because COPD remains a leading cause of death and disability in the U.S., and racial disparities persist in respiratory outcomes, continuing to identify risk factors for vulnerable groups could assist health program planners with development of successful health messaging.

Objective: Placental abruption is associated with adverse perinatal outcomes including intrauterine fetal demise, which subsequently results in stillbirth. However, few studies have demonstrated the preventability of stillbirth due to placental abruption. Therefore, we evaluated the possibility of preventing stillbirth caused by placental abruption by reviewing all stillbirths in our region., Methods: This study reviewed all stillbirths after 22 weeks of gestation in Shiga Prefecture, Japan from 2010 to 2019, excluding lethal disorders. We evaluated 350 stillbirth cases, with and without placental abruption., Results: There were 32 stillbirths with PA and 318 without placental abruption. The probability of preventing stillbirth was significantly higher in patients with placental abruption than in those without (30% vs. 8%, p  < 0.001). We also determined the recommendations for preventing stillbirths with placental abruption., Conclusion: Some stillbirths caused by placental abruption can be prevented. We recommend improvements to perinatal maternal-fetal care and perinatal emergency transport systems.

Background: Although stroke is prevalent among Chinese, individuals with stroke may become more disabling if they have concomitant neck pain (NP) and low back pain (LBP). However, the prevalence and factors associated with post-stroke spinal pain among Chinese remain unknown. The current study used the 2018 cohort data from the China Health and Aged Care Tracking Survey (CHARLS) to determine the prevalence and factors associated with increased post-stroke NP and LBP in China., Methods: The CHARLS study was conducted on four cohorts of nationally representative samples of individuals aged 45 years and above from 30 provincial-level administrative units in China. We used data from the 2018 cohort of the CHARLS survey to determine the prevalence and factors associated with NP and LBP in the non-stroke and post-stroke populations. Participants aged 45 years or older who reported to have NP, and/or LBP were identified. The study was statistically analyzed using t-test, and ANOVA analysis of variance. A multiple logistic regression model was used to identify factors significantly associated with NP and/or LBP in the non-stroke and post-stroke populations., Results: A total of 19,816 individuals participated in the 2018 survey. The final inclusion of 17,802 subjects who met the criteria included 16,197 non-stroke and 885 stroke participants. The prevalence of NP and LBP in non-stroke population was 17.80% (95% CI: 17.21-18.39) and 37.22% (95% CI: 36.47-37.96), respectively. The prevalence of NP and LBP in the target stroke population was 26.44% (95% CI: 23.53-29.35) and 45.42% (95% CI: 42.14-48.71), respectively, and the difference was statistically significant (p < 0.05). Factors associated with increased post-stroke NP included female, short sleep duration, long lunch break, physical dysfunction, and depression. Factors associated with increased post-stroke LBP included female, comorbidities of two or more chronic diseases, physical dysfunction, and depression., Conclusion: The current study highlighted the high prevalence of post-stroke neck pain (26.44%) and LBP (45.42%) in China. While slightly different associated factors were found to be associated with a higher prevalence of post-stroke NP and LBP, female and individuals with more physical dysfunction or depression were more likely to experience post-stroke spinal pain. Clinicians should pay more attention to vulnerable individuals and provide pain management measures., (© 2024. The Author(s).)

Background: Diabetes mellitus (DM) and Helicobacter pylori infection (HPI) pose increasing public health challenges in aging societies, sharing common pathophysiological mechanisms, and linked to significant health risks. Our study examines their respective impacts on all-cause and cardiovascular mortalities in a comprehensive longitudinal population-based analysis., Methods: The study analyzed data from the National Health and Nutrition Examination Survey (NHANES) database conducted between 1999 and 2019, which included information on Diabetes mellitus status and Helicobacter pylori infection status. Mortality data were obtained from the same database mentioned above., Results: Among the 2719 participants, 1362 (50.1%) were free of both diabetes mellitus (DM) and Helicobacter pylori infection (HP) (DM -/HP -), 140 (5.1%) had DM alone (DM +/HP -), 1011 (37.2%) had HP alone (DM -/HP +), and 206 (7.6%) had both DM and HP (DM +/HP +). Compared to the DM -/HP - group, the DM +/HP - and DM + /HP + groups demonstrated increased all-cause mortality with adjusted hazard ratios (HRs) of 1.40 (95% [CI] 1.07-1.78) and 1.46 (95% CI 1.15-1.84), respectively. For diabetic mortality, DM +/HP- group and DM + /HP + group showed increased HR of 6.30 (95% CI 1.30-30.43) and 8.56 (95% CI 1.98-36.94), respectively. For cardiovascular mortality, the DM + /HP- group and DM + /HP + group exhibited increased HR of 1.75 (95% CI 1.14-2.69) and 1.98 (95% CI 1.40-2.79), respectively. The DM + /HP + cohort displayed the highest risk of overall mortality (p for trend = 0.003), diabetic mortality (p for trend < 0.0001), an6d cardiovascular mortality (p for trend < 0.0001)., Conclusions: The concurrent presence of DM and Helicobacter pylori infection significantly amplifies the risk of all-cause, cardiovascular, and diabetic mortality. Individuals with either condition may necessitate heightened management to prevent the onset of the other ailment and reduce mortality rates., (© 2024. The Author(s).)
