Numerous studies have suggested that the hemoglobin-to-red blood cell distribution width ratio (HRR) is associated with the onset, progression, and prognosis of various diseases. However, to the best of our knowledge, no research has conducted statistical analyses to determine the association between HRR and stroke. This cross-sectional study was conducted among adults with complete data on hemoglobin-red cell distribution width ratio (HRR) and stroke from the 2005–2018 National Health and Nutrition Examination Survey (NHANES). HRR was calculated by dividing hemoglobin (HGB) in grams per deciliter (g/dL) by the red blood cell distribution width (RDW). Weighted multivariable logistic regression and generalized additive models were employed to investigate the independent and nonlinear relationships between HRR and stroke. Threshold effects were assessed using two-piece linear regression models. Additionally, subgroup analyses and interaction tests were performed. A total of 36,215 participants were included, with 2.92% classified as stroke patients. The prevalence of stroke decreased across increasing tertiles of HRR (Q1: 5.07%; Q2: 2.63%; Q3: 1.69%; P < 0.0001). A negative association between HRR and stroke was observed in both unadjusted and adjusted models. In Model III, each one-unit increase in HRR was associated with a 58% reduction in the likelihood of stroke (Model III: OR = 0.42, 95% CI: 0.29–0.63). Subgroup analyses and interaction tests revealed that the association between HRR and stroke was BMI-dependent (P < 0.05), with the negative association only observed in participants with BMI < = 25 and BMI 25–30, but not in those with BMI > 30. Using a two-piece linear regression model, a threshold effect was identified at a BMI of 30 (K = 1.16). To the left of this breakpoint, there was a negative association between HRR and stroke (OR = 0.55, 95% CI: 0.27–0.97), whereas no such association was detected to the right of the breakpoint (OR = 6.49, 95% CI: 0.75–56.11). HRR is negatively associated with the likelihood of stroke, with a lower risk of stroke in individuals with higher HRR levels. [ABSTRACT FROM AUTHOR]

Aims Methods Results Conclusions The aim of this study is to determine the prevalence of impaired awareness of hypoglycaemia (IAH) and examine risk factors for IAH in adults with type 1 diabetes.We conducted a population‐based registry study of 10,202 adults (≥18 years) with type 1 diabetes using data from the Norwegian Diabetes Register for Adults. The registry used the 1‐item Gold scale, measuring hypoglycaemia symptom awareness. We calculated the overall prevalence of IAH (Gold score ≥4) (95% CI) and prevalence for subgroups based on demographic and clinical variables. We estimated IAH prevalence based on continuous scales of age, diabetes duration and HbA1c using predicted probabilities from generalised additive logistic regression models. Finally, we quantified the associations of selected variables on IAH prevalence using log‐binomial regression models.Overall, 18.0% reported IAH (95% CI 17.2, 18.7). The prevalence increased linearly with the participants' age, whereas the associations of diabetes duration and HbA1c with IAH were non‐linear with higher prevalence in both lower and higher tails of their distributions. Multiple severe hypoglycaemic events, female sex, age ≥ 65 years, diabetes duration ≤4 years or ≥ 30 years, multiple DKA events and CGM use were associated with higher risk for IAH. HbA1c 65–74 mmol/mol (8.1–8.9%) was associated with lower risk for IAH.In this nationwide study, the IAH prevalence was 18.0%. Multiple hypoglycaemic events, female sex and diabetes duration were identified as important risk factors for IAH. Study findings highlight the complexity of self‐reported hypoglycaemia symptom awareness and emphasise the importance of routinely addressing symptom awareness in diabetes follow‐up.

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. Epidemiological cohort study. 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. 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. 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.

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.

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. Synopsis: A population‐based cohort study to investigate the association between myomectomy‐to‐pregnancy interval and obstetric outcomes. [ABSTRACT FROM AUTHOR]

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.

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.

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. [ABSTRACT FROM AUTHOR]

Purpose Methods Results Conclusion 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.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.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).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. [ABSTRACT FROM AUTHOR]

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.

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. This article is part of a Special Collection on Gynecological Cancers. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the prevalence and associated factors of pseudoexfoliation syndrome (PEX) in an Iranian elderly population. Methods: This study, a population-based cross-sectional study conducted on individuals ≥60 years in Tehran, the capital of Iran in 2019 using a multi-stage stratified random cluster sampling. All study participants underwent complete ocular examination (including measurement of uncorrected and best-corrected visual acuity, refraction, slit-lamp biomicroscopy). The PEX was diagnosed based on the presence of white fluffy dandruff-like pseudoexfoliative material on the pupillary margin, on the anterior lens capsule, and/or the trabecular meshwork. Results: Of the 3791 invitees, 3310 participated in the TGES (response rate: 87.3%). After applying exclusion criteria, the data of 3274 individuals were analyzed for this report. The overall prevalence of PEX was 3.63% (95% CI:2.67–4.58) in this study. 81.1% of PEX cases were bilateral. The prevalence of PEX increased significantly with advancing age in a linear trend from 2.38% (95%: 1.27–3.48) in the age group 60–64 years to 6.48% (95%: 2.02–10.95) in the age group ≥80 years (OR = 1.05, p = 0.008). According to the multiple logistic regression model, advancing age (OR: 1.06, p = 0.002) and the presence of cataract (OR: 5.02, p < 0.001) were significantly associated with increased odds of PEX. Conclusion: The results showed a lower prevalence of PEX in the Iranian elderly compared to previous studies on the elderly population. Advancing age and cataracts were the only associated factors of PEX in the present study. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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 (PRSAPOE) and without (PRSnon‐APOE) apolipoprotein E (APOE) gene. In the longitudinal analysis, PRSAPOE was associated with a multivariable‐adjusted hazards ratio of 1.91 (95% CI = 1.13–3.23) for AD. PRSAPOE 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. PRSnon‐APOE showed an association with AD risk similar to PRSAPOE. PRSAPOE, but not PRSnon‐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 PRSAPOE. Highlights: The PRSAPOE and PRSnon‐APOE were associated with AD risk in the Chinese population.The PRSAPOE and PRSnon‐APOE, in combination with demographics, showed good discriminative and predictive ability for AD.The AD‐related pathologies underlie the AD risk associated with PRSAPOE but not PRSnon‐APOE.

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 log2SII 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/m2) 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. [ABSTRACT FROM AUTHOR]

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.

Purpose Methods Results Conclusion To delineate the current trends regarding gender‐affirming surgeries (GAS) in Germany.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.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).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. [ABSTRACT FROM AUTHOR]

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.

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. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to examine the potential factors associated with marital status and determine the association between marital status and cognitive impairment in a multi-ethnic Asian population. Method: This study included 2,321 participants from Singapore Multi-Ethnic Cohort revisit study (aged 40–89). Participants were classified into married and unmarried group at baseline and follow-up according to self-reported marital status. Mini-Mental Status Examination (MMSE) was administered, and cognitive impairment was defined as a MMSE <26. We conducted both cross-sectional and longitudinal analyses to examine the association of marital status at 1 timepoint as well as marital transition with cognitive impairment. Results: Of the 2,321 participants, a total of 1,914 (82.5%) were married. The factors associated with marital status included younger age, male sex, higher household income, higher education, and higher physical activity levels. Additionally, married participants also had higher alternative healthy eating index (AHEI-2010) scores and a lower burden of hypertension and diabetes. Among those who were married, the median (Q1, Q3) MMSE score was 29 (28, 30) while among those who were unmarried it was 29 (27, 30) (p < 0.01). Participants who had never been married had the highest odds of cognitive impairment compared to their married counterparts (model III: OR = 1.48, 95% CI: 1.03, 2.14). Older age (p interaction value = 0.003) and Indian ethnicity (p interaction value = 0.028) further strengthened these associations. Conclusion: Marriage was associated with lower odds of cognitive impairment. Marriage provides social support, companionship, and engagement in mentally stimulating activities contributing to better cognitive health. By identifying risk factors such as marital status, interventions and support systems can be developed to promote healthy cognitive aging. [ABSTRACT FROM AUTHOR]

Abstract Numerous studies have suggested that the hemoglobin-to-red blood cell distribution width ratio (HRR) is associated with the onset, progression, and prognosis of various diseases. However, to the best of our knowledge, no research has conducted statistical analyses to determine the association between HRR and stroke. This cross-sectional study was conducted among adults with complete data on hemoglobin-red cell distribution width ratio (HRR) and stroke from the 2005–2018 National Health and Nutrition Examination Survey (NHANES). HRR was calculated by dividing hemoglobin (HGB) in grams per deciliter (g/dL) by the red blood cell distribution width (RDW). Weighted multivariable logistic regression and generalized additive models were employed to investigate the independent and nonlinear relationships between HRR and stroke. Threshold effects were assessed using two-piece linear regression models. Additionally, subgroup analyses and interaction tests were performed. A total of 36,215 participants were included, with 2.92% classified as stroke patients. The prevalence of stroke decreased across increasing tertiles of HRR (Q1: 5.07%; Q2: 2.63%; Q3: 1.69%; P 30. Using a two-piece linear regression model, a threshold effect was identified at a BMI of 30 (K = 1.16). To the left of this breakpoint, there was a negative association between HRR and stroke (OR = 0.55, 95% CI: 0.27–0.97), whereas no such association was detected to the right of the breakpoint (OR = 6.49, 95% CI: 0.75–56.11). HRR is negatively associated with the likelihood of stroke, with a lower risk of stroke in individuals with higher HRR levels.

Abstract 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

Abstract 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

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

In multivariable weighted linear regression, each level increase in log2SII 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/m2) 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.

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.Keywords: NHANES, population-based study, systemic immune-inflammation index, pulmonary function

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.

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 m2) 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.

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 (pnon‐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. Highlights: Dietary vitamin C intake was inversely associated with migraine.There was a linear negative relationship between vitamin C intake and migraine. [ABSTRACT FROM AUTHOR]

Purpose: To determine the distribution of macular thickness and macular volume in an elderly healthy population 60 years of age and above and their determinants. Methods: The sampling was performed using a multistage stratified random cluster sampling method on the geriatric population 60 years of age and above in Tehran, Iran. All participants underwent optometric examinations, slit-lamp examination, and optical biometry. Retinal imaging was performed by spectral-domain optical coherence tomography. Results: The means ± standard deviation and 95% confidence interval of central macular thickness (CMT), average macular thickness (AMT), and macular volume were 221 ± 33 (218–223) μm, 267 ± 29 (265–269) μm, and 8.36 ± 0.44 (8.33–8.39) mm3, respectively. The CMT was significantly lower in females than males (β: −5.77; P = 0.002). The AMT was significantly lower in females than males (β = −10.32; P < 0.001) and was significantly directly related to intraocular pressure (β = 0.63; P = 0.038). The macular volume was significantly lower in females than males (β = −0.13; P < 0.001) and decreased with age (β = −0.01; P < 0.001). In addition, the macular volume had a significant inverse and direct relationship with axial length (β = −0.04; P = 0.011) and keratometry (β = 0.03; P < 0.001). Conclusions: Macular thickness in the Iranian geriatric population was slightly less than the populations studied in other countries. The role of sex should also be taken into account in the interpretation of macular thickness findings.

Abstract 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

Abstract 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

Abstract Background Major depressive disorder (MDD) is a disabling mental illness that can affect all aspects of daily life and is a leading cause of healthcare resource utilisation (HCRU). Aims We aimed to characterise patients with MDD with moderate-to-high-suicide-intent, compare their HCRU to patients with MDD without moderate-to-high-suicide-intent, and better understand their patient pathways. Methods This retrospective cohort study used data collected from primary care electronic health records from Clinical Practice Research Datalink (CPRD), linked to Hospital Episode Statistics, Mental Health Services Data Set, and Office for National Statistics in England. Adults diagnosed with ≥ 1 MDD diagnosis between 04/2007 and 11/2015 were categorised by suicide intent. Results 307,476 patients with MDD were included (294,259 patients without moderate-to-high-suicide-intent and 13,217 with moderate-to-high-suicide-intent). Patients with MDD with moderate-to-high-suicide-intent were younger on average (39.0 vs. 44.8 years) and included a lower percentage of females (58% vs. 65%) compared to patients without moderate-to-high-suicide-intent. HCRU was greater among patients with moderate-to-high-suicide-intent than patients without moderate-to-high-suicide-intent during the first follow-up year for general practitioner consultations (38.5 vs. 29.4), psychiatric outpatient visits (1.5 vs. 0.1), psychiatrist visits (3.6 vs. 0.3), emergency visits (1.5 vs. 0.3), and hospitalisations (86% vs. 26%). Overall, 56% of patients with moderate-to-high-suicide-intent had an antidepressant prescription within 30 days from the initial moderate-to-high-suicide-intent. Conclusions Patients with MDD and moderate-to-high-suicide-intent were younger, included more males and incurred greater HCRU than those without moderate-to-high-suicide-intent. These results suggest a greater need for effective medical care and appropriate treatments for patients with moderate-to-high-suicide-intent, which could help reduce associated symptoms, mortality, and HCRU.

Abstract Purpose The atherogenic index of plasma (AIP) is a novel comprehensive lipid index. We aimed to investigate a possible relationship between AIP index and kidney stones in US adults. Methods This cross-sectional study was conducted among adults with complete AIP index and questionnaire records on kidney stones from the National Health and Nutrition Examination Survey (NHANES) spanning from 2007 to 2018. The AIP index served as the exposure variable, defined as the logarithm of the ratio between triglycerides (TG, mmol/L) and high-density lipoprotein cholesterol (HDL-c, mmol/L). Self-reported history of kidney stones was utilized as the outcome variable. The independent relationship between AIP index and the risk of kidney stones was fully assessed. Results A total of 14,833 participants were included in this study, with an average AIP index of -0.07 ± 0.01. The proportion of kidney stones progressively increased with higher AIP index tertile intervals (7.33% vs. 9.97% vs. 12.57%, P 0.05). Conclusions The AIP index may be a potential epidemiological tool to quantify the role of dyslipidemia in the risk of kidney stones in US adults.

Abstract MicroRNAs (miRNAs) are small non-coding RNAs involved in post-transcriptional regulation of gene expression. Mounting evidence underscores the dysregulation of miRNAs to be associated with cancer development and progression by acting as tumour suppressors and oncogenes. However, their potential as biomarkers for early diagnosis of different cancers remains incompletely unraveled. We explored the relationship between plasma circulatory miRNAs and cancer risk within the population-based Rotterdam Study cohort. Plasma samples were collected at baseline (between 2002 and 2005) and miRNA levels were measured in 1,999 participants, including 169 prevalent cancer cases. The occurrence of cancer was assessed by continuous monitoring of medical records in 1,830 cancer-free participants until January 1, 2015. We assessed the association between incidence of five common cancers (blood, lung, breast, prostate, and colorectal) and 591 miRNAs well-expressed in plasma, using adjusted Cox proportional-hazards regression models. Our longitudinal analysis identified 13 miRNAs significantly associated with incident hematologic tumors surpassing the Bonferroni-corrected P

Abstract Background Obesity is characterized by a chronic low-grade inflammatory condition. Two emerging inflammatory biomarkers, the systemic immune-inflammation index (SII) and the systemic inflammation response index (SIRI), have gained attention. However, the relationships between obesity and SII/SRI remain unclear. Methods In this study, we analyzed data from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018 among adults. SII-SIRI/SII/SIRI were categorized into three groups based on tertiles. The association between obesity and SII-SIRI/SII/SIRI was assessed by multivariable logistic regression models. Restricted cubic spline (RCS) plots were used to examine the nonlinear association between obesity and SII/SIRI. Finally, potential independent associations between obesity and SII/SIRI were further explored using subgroup analyses. Results The study included 20,011 adults, of whom 7,890 (39.32%) were obesity. In model 1, participants in the high (Q3) level of SII-SIRI had a significantly association with obesity than those in the low (Q1) level group. The high level of SII and SIRI were positively associated with obesity as compared to low levels. Model 2 revealed a positive association between obesity and high levels of SII-SIRI/SII/SIRI. Model 3 demonstrated a similar trend. RCS curves revealed a nonlinear association linking obesity to SII/SIRI. Subgroup analysis showed an interaction between SII/SIRI and age. Conclusions Our research suggested that obesity was positively associated with SII-SIRI/SII/SIRI in U.S. adults. SII/SIRI may represent a cost-effective and direct approach to assessing obesity.

Abstract Background Previous findings have revealed that disorders of lipid metabolism may be a risk factor for pulmonary function damage; however, the combined effect of dyslipidemia and central obesity on pulmonary function is unclear. The cardiometabolic index (CMI) is a composite of serum lipids (triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C)) and visceral fat parameters (waist-to-height ratio (WHtR)). This research aimed to investigate the link between CMI and pulmonary function, employing large-scale demographic data sourced from the National Health and Nutrition Examination Survey (NHANES) database. Methods This cross-sectional study used data involving 4125 adults aged 20 and above collected by NHANES between 2007 and 2012. We defined CMI as the exposure variable and measured outcomes using forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC to evaluate pulmonary function. Weighted multiple linear regression models and subgroup analyses were employed to investigate separate relationships between CMI and pulmonary function. In addition, to investigate variations across different strata and evaluate the robustness of the findings, interaction tests and sensitivity analyses were conducted. Results Results from the weighted multiple linear regression analysis indicated a unit increase in log2-CMI was associated with a reduction of 82.63 mL in FEV1 and 112.92 mL in FVC. The negative association remained significant after transforming log2-CMI by quartile (Q). When the log2-CMI level reached Q4, β coefficients (β) were -128.49 (95% CI: -205.85, -51.13), -169.01 (95% CI: -266.72, -71.30), respectively. According to the interaction test findings, the negative association linking log2-CMI with FEV1 and FVC persists regardless of confounding factors including age, gender, BMI, physical activity (PA), and smoking status. A subsequent sensitivity analysis provided additional confirmation of the stability and reliability of the results. For females, the inflection points for the nonlinear relationships between log2-CMI and FEV1, as well as log2-CMI and FVC, were identified at 2.33 and 2.11, respectively. While in males, a consistent negative association was observed. Conclusions Our findings suggest that higher CMI is associated with lower FEV1 and FVC. CMI may serve as a complementary consideration to the assessment and management of pulmonary function in clinical practice.

Aims: Achilles tendon re-rupture (ATRR) poses a significant risk of postoperative complication, even after a successful initial surgical repair. This study aimed to identify risk factors associated with Achilles tendon re-rupture following operative fixation. Methods: This retrospective cohort study analyzed a total of 43,287 patients from national health claims data spanning 2008 to 2018, focusing on patients who underwent surgical treatment for primary Achilles tendon rupture. Short-term ATRR was defined as cases that required revision surgery occurring between six weeks and one year after the initial surgical repair, while omitting cases with simultaneous infection or skin necrosis. Variables such as age, sex, the presence of Achilles tendinopathy, and comorbidities were systematically collected for the analysis. We employed multivariate stepwise logistic regression to identify potential risk factors associated with short-term ATRR. Results: From 2009 to 2018, the short-term re-rupture rate for Achilles tendon surgeries was 2.14%. Risk factors included male sex, younger age, and the presence of Achilles tendinopathy. Conclusion: This large-scale, big-data study reaffirmed known risk factors for short-term Achilles tendon re-rupture, specifically identifying male sex and younger age. Moreover, this study discovered that a prior history of Achilles tendinopathy emerges as an independent risk factor for re-rupture, even following initial operative fixation.

Abstract Objectives This study aimed to investigate the associations between changes in blood pressure (BP) and cerebral small vessel disease (CSVD). Methods This study included 401 participants in the magnetic resonance imaging (MRI) sub-study conducted between 2018 and 2020 as a part of the Multidomain Interventions to Delay Dementia and Disability in Rural China project. MRI markers of CSVD were assessed based on international criteria. Individualized linear regression models evaluated changes in BP by estimating the trend of blood pressure changes over time and fitting a straight line from 2014 to 2018. The data were analyzed using logistic and general linear regression models. Result The mean age of the participants was 64.48 ± 2.69 years, with 237 (59.1%) being females. Increases in systolic BP in later life were significantly associated with larger volumes of periventricular white matter hyperintensity (WMH), greater perivascular spaces in the basal ganglia (BG-PVS) burden, and the presence of deep lacunes and cerebral microbleeds. Additionally, increases in diastolic BP in later life were significantly associated with the presence of infratentorial and deep lacunes. Conclusions CSVDs are associated with increased exposure to elevated BP later in life.

Abstract Background Although prisoner health is a topic of significant importance, it has received limited attention in epidemiological studies, likely due to challenges in obtaining data. Therefore, this study aimed to investigate the prevalence of skin diseases among elderly prisoners in Taiwan. Methods We examined the presence of skin diseases in 2215 elderly prisoners based on the International Classification of Diseases, 9th revision Clinical Modification (ICD-9-CM). Additionally, the most common types of skin diseases among elderly prisoners in Taiwan were identified. Results The prevalence of skin diseases among prisoners was estimated to be 55.03%. Elderly men prisoners exhibited a higher prevalence of skin diseases than the women prisoners. The most common skin diseases observed were as follows: contact dermatitis and other forms of eczema; pruritus and related conditions; cellulitis and abscesses; and urticaria. Conclusion Skin diseases were identified in more than half of the elderly prisoners. The overall quality of life of elderly prisoners can be improved by addressing their skin health, which would contribute to the fulfilment of their basic human rights. Clinical trials number NA.

Abstract Background India is a large and populous country where reliable data on headache disorders are relatively scarce. This study in northern India (Delhi and National Capital Territory Region [NCR], including surrounding districts in the States of Haryana, Uttar Pradesh and Rajasthan) continues the series of population-based studies within the Global Campaign against Headache and follows an earlier study, using the same protocol and questionnaire, in the southern State of Karnataka. Methods This cross-sectional study used the Global Campaign’s established methodology. Biologically unrelated Indian nationals aged 18–65 years were included through multistage random sampling in both urban and rural areas of NCR. Interviews at unannounced household visits followed the structured Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire in its original English version or in the validated Hindi version. Demographic enquiry was followed by a neutral headache screening question and diagnostic questions based on the International Classification of Headache Disorders edition 3 (ICHD-3), which focused on each respondent’s most bothersome headache. Questions about headache yesterday (HY) enabled estimation of 1-day prevalence. A diagnostic algorithm first identified participants reporting headache on ≥ 15 days/month (H15+), diagnosing probable medication-overuse headache (pMOH) in those also reporting acute medication use on ≥ 15 days/month, and “other H15+” in those not. To all others, the algorithm applied ICHD-3 criteria in the order definite migraine, definite tension-type headache (TTH), probable migraine, probable TTH. Definite and probable diagnoses were combined. Results Adjusted for age, gender and habitation, 1-year prevalences were 26.3% for migraine, 34.1% for TTH, 3.0% for pMOH and 4.5% for other H15+. Female preponderance was seen in all headache types except TTH: migraine 35.7% vs. 15.1% (aOR = 3.3; p

Abstract Background There are limited population-representative data that describe the potential burden of Post-COVID conditions (PCC) in Mexico. We estimated the prevalence of PCC overall and by sociodemographic characteristics among a representative sample of adults previously diagnosed with COVID-19 in Mexico. We additionally, characterized the PCC symptoms, and estimated the association between diagnosed type-2 diabetes and hypertension with PCC. Methods We used data from the 2021 National Health and Nutrition Survey in Mexico, a nationally and regionally representative survey, from August 1st to October 31st, 2021. Using the WHO definition, we estimated the prevalence of PCC by sociodemographics and prevalence of PCC symptoms. We fit multivariable log-binomial regression models to estimate the associations. Results The prevalence of PCC was 37.0%. The most common persistent symptoms were fatigue (56.8%), myalgia or arthralgia (47.5%), respiratory distress and dyspnea (42.7%), headache (34.0%), and cough (25.7%). The prevalence was higher in older people, women, and individuals with low socioeconomic status. There was no significant association between hypertension and PCC or diabetes and PCC prevalence. Conclusions About one-third of the adult Mexican population who had COVID-19 in 2021 had Post-COVID conditions. Our population-based estimates can help assess potential priorities for PCC-related health services, which is critical in light of our weak health system and limited funding.

The study involved analyzing fundus photographs of 6855 participants, aged 35 to 74, to assess signs of HR, classified according to the Mitchell-Wong Classification. The research aimed to explore the correlation between fetal growth restriction indicated by BW and the frequency of HR. The results showed that the frequency of HR did not significantly differ among groups with different BW ranges. In the univariable analysis, HR was initially associated with high BW, but this association disappeared after adjusting for age, sex, and cardiovascular risk factors. No association was found between low BW and HR. The study reveals novel insights as there are no prior population-based studies specifically exploring this association.Keywords: birth weight, hypertensive retinopathy, epidemiology, population-based study

Abstract The human oral microbiome may alter oral and systemic disease risk. Consuming high sugar content beverages (HSB) can lead to caries development by altering the microbial composition in dental plaque, but little is known regarding HSB-specific oral microbial alterations. Therefore, we conducted a large, population-based study to examine associations of HSB intake with oral microbiome diversity and composition. Using mouthwash samples of 989 individuals in two nationwide U.S. cohorts, bacterial 16S rRNA genes were amplified, sequenced, and assigned to bacterial taxa. HSB intake was quantified from food frequency questionnaires as low ( 3 servings/week). We assessed overall bacterial diversity and presence of specific taxa with respect to HSB intake in each cohort separately and combined in a meta-analysis. Consistently in the two cohorts, we found lower species richness in high HSB consumers (> 3 cans/week) (p = 0.027), and that overall bacterial community profiles differed from those of non-consumers (PERMANOVA p = 0.040). Specifically, presence of a network of commensal bacteria (Lachnospiraceae, Peptostreptococcaceae, and Alloprevotella rava) was less common in high compared to non-consumers, as were other species including Campylobacter showae, Prevotella oulorum, and Mycoplasma faucium. Presence of acidogenic bacteria Bifodobacteriaceae and Lactobacillus rhamnosus was more common in high consumers. Abundance of Fusobacteriales and its genus Leptotrichia, Lachnoanaerobaculum sp., and Campylobacter were lower with higher HSB consumption, and their abundances were correlated. No significant interaction was found for these associations with diabetic status or with microbial markers for caries (S. mutans) and periodontitis (P. gingivalis). Our results suggest that soft drink intake may alter the salivary microbiota, with consistent results across two independent cohorts. The observed perturbations of overrepresented acidogenic bacteria and underrepresented commensal bacteria in high HSB consumers may have implications for oral and systemic disease risk.

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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Background: Breast cancer (BC) affects racial and ethnic groups differently, leading to disparities in clinical presentation and outcomes. It is unclear how Hispanic ethnicity affects BC outcomes based on geographic location and proximity to the United States (U.S.)/Mexico border. We hypothesized that the impact of race/ethnicity on BC outcomes depends on geographic location and country of origin within each BC subtype. Methods: We analyzed BC data from the Texas Cancer Registry by race/ ethnicity/birthplace according to BC subtype (luminal A/luminal B/human epidermal growth factor receptor 2 [HER2]/triple-negative breast cancer [TNBC]). Other covariates included age, geographic location (U.S., Mexico), residency (border, non-border), treatments, and comorbidities. Crude and adjusted effects of race/ethnicity and birthplace on overall survival (OS) were analyzed using Cox regression methods. Results: Our analysis of 76,310 patient records with specific BC subtypes revealed that Hispanic and non-Hispanic Black (NHB) patients were diagnosed at a younger age compared with non-Hispanic White (NHW) patients for all BC subtypes. For the 19,748 BC patients with complete data on race/ethnicity/ birthplace/residency, Hispanic patients had a higher mortality risk in the Luminal A subtype, regardless of birthplace, whereas U.S.-born Hispanics had a higher risk of death in the TNBC subtype. In contrast, NHB patients had a higher mortality risk in the Luminal A and HER2 subtypes. Residence along the U.S./Mexico border had little impact on OS, with better outcomes in Luminal A patients and worse outcomes in Luminal B patients aged 60–74 years. Conclusion: Race/ethnicity, geographic birth location, and residency were significant predictors of survival in BC. Migration, acculturation, and reduced healthcare access may contribute to outcome differences. [ABSTRACT FROM AUTHOR]
