Stroke is a leading cause of mortality and disability globally, with post-stroke depression and post-stroke anxiety being common and significant complications that hinder recovery and adversely affect quality of life. Although these conditions frequently co-occur, their heterogeneity remains poorly understood. This study integrates the Health Ecology Model (HEM) and employs Latent Profile Analysis (LPA) to identify distinct psychological profiles of depression and anxiety among patients with acute ischemic stroke (AIS), as well as to investigate their multilevel determinants. Patients with AIS from a tertiary hospital in Guangdong Province, China, from January to November 2024 were included. Within one week of stroke onset, the data of sociodemographic, clinical characteristics, swallowing function, stroke severity, activities of daily living, resilience and social support were collected according to the HEM guidelines. The Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7 were used to assess the depression and anxiety symptoms of the patients three months after stroke onset. LPA was employed to identify distinct psychological profiles, and variables with a A total of 551 patients with AIS were included in the study, 49 were lost to follow-up or withdrew, resulting in a final analytic sample of 502 participants (91.11%). Three distinct psychological profiles were identified: no depression-anxiety (67.93%), high-risk depression-anxiety (21.12%) and major depression-anxiety (10.95%). In the multivariate analysis, the results indicated that occupation (OR = 0.61, 95% CI [0.40-0.93]), National Institutes of Health Stroke Scale (NIHSS, OR = 1.60, 95% CI [1.06-2.42]), Barthel Index (BI, OR = 1.67, 95% CI [1.27-2.19]) and hypertension (OR = 2.37, 95% CI [1.29-4.35]) were independent predictors of the high-risk depression-anxiety profile, while NIHSS (OR = 2.33, 95% CI [1.42-3.85]), BI (OR = 2.65, 95% CI [1.62-4.35]) and resilience (OR = 0.92, 95% CI [0.87-0.98]) were significantly associated with the major depression-anxiety profile. This study reveals significant heterogeneity in psychological distress among AIS survivors. Key predictors of post-stroke emotional comorbidity include occupation, hypertension, stroke severity, activities of daily living and low resilience. Early identification of high-risk individuals can significantly enhance screening and intervention strategies, particularly by focusing on symptoms such as anhedonia and nervousness. Future research should focus on longitudinal designs and objective biomarkers to better understand the mechanisms behind post-stroke emotional comorbidity. Show less

Cognitive decline is a common aspect of aging, and identifying modifiable lifestyle factors, such as physical activity and sleep, is crucial for promoting healthy brain aging. While both are individually linked to cognition, few studies have simultaneously assessed their independent and combined effects using objective wearable-based data, particularly in older Asian populations. This study aimed to examine the independent and interactive effects of wearable-assessed sleep and physical activity parameters on memory performance in healthy older adults. We also explored whether age and hippocampal volume moderated these associations. This prospective cross-sectional analysis included 88 cognitively healthy community-dwelling adults (≥60 years of age) from the Integrating Systematic Data of Geriatric Medicine to Explore the Solution for Healthy Aging cohort in Taiwan. Participants underwent 12-day wrist-worn actigraphy, brain magnetic resonance imaging, and neuropsychological assessments. Light-intensity physical activity (LPA) and wake after sleep onset (WASO) were selected based on age-adjusted partial correlations with Consortium to Establish a Registry for Alzheimer's Disease Neuropsychological Battery memory scores. Multivariate regressions, age-stratified models (cutoff=72 years), and PROCESS moderation and mediation analyses were conducted, adjusting for age, education, daytime sleepiness, and hippocampal volume. Partial correlation analyses adjusting for age showed that higher LPA (r=0.260; P=.02) and lower WASO (r=-0.251; P=.02) were significantly associated with better memory scores. Age significantly moderated both effects: LPA was beneficial beyond 73.8 years of age, and WASO was detrimental beyond 71.1 years of age. Multivariate regression models confirmed that both WASO (β=-.044; P=.04) and LPA (β=.042; P=.01) were significant predictors of memory. In subgroup analyses (age ≥72 years), both LPA (β=.054; P=.04) and WASO (β=-.111; P=.01) remained significant predictors. Moderated mediation analyses showed that WASO was associated with reduced LPA (β=-.325; P=.03), but the indirect effect on memory via LPA was not significant. Instead, WASO exerted a direct and age-moderated effect on memory performance. Hippocampal volume moderated both associations, supporting the brain reserve hypothesis. Our findings highlight WASO and LPA, as measured by wearable devices, as modifiable behavioral factors linked to memory function in older adults. The impact of these factors intensifies with advancing age and may be influenced by hippocampal reserve. Promoting daily light physical activity and maintaining sleep continuity may serve as accessible, age-tailored strategies for preserving cognitive health in aging populations.

Although light-intensity physical activity (LPA) has been suggested to be associated with a lower risk of mortality, the minimal and optimal volumes of LPA remain unclear. We aimed to examine the minimal and optimal volumes of LPA associated with the risks of mortality and disease incidence (i.e., cardiovascular diseases and cancer). Data were derived from the population-based UK Biobank cohort study, including 69,492 adults aged 43-78 years. Accelerometer-measured LPA was defined using a validated, published machine learning-based Random Forest activity method, which was categorized into 4 quartile groups. All-cause and cause-specific mortality (cardiovascular disease- and cancer-specific) were determined according to the International Classification of Diseases, 10th version codes. Disease incidence was defined based on primary care, hospitalization, or death records. During a median follow-up period of 8.04 years, 2024 adults died from all causes, 539 from cardiovascular disease, and 1175 from cancer. For all-cause mortality, compared with participants in the lowest quartile of LPA (<3.9 h/day), the hazard ratios (HRs) and 95% confidence intervals (95%CIs) were 0.82 (95%CI: 0.73‒0.93) for those with 3.9 to <5.0 h/day, 0.75 (95%CI: 0.66‒0.85) for those with 5.0 to <6.1 h/day, and 0.77 (95%CI: 0.68‒0.88) for those with ≥6.1 h/day, respectively. There was an inverse non-linear dose-response association between LPA and all-cause mortality, with an optimal dose of 5.72 h/day (95%CI: 5.45‒6.41; HR = 0.63, 95%CI: 0.56‒0.71) and a minimal dose of 3.59 h/day (95%CI: 3.53-8.56; HR = 0.81, 95%CI: 0.78‒0.86), with the 5th percentile as the reference. Similar patterns were observed for cause-specific mortality and disease incidence (cardiovascular disease and cancer). Engaging in LPA for ∼3.5 h/day was conservatively associated with lower risk of mortality and disease incidence, with further risk reductions observed up to an optimal dose of ∼6.0 h/day. These findings suggest that sufficient LPA offers important health benefits, which can inform the development of future PA guidelines. Show less

Incontinence-associated dermatitis (IAD) is a common nursing challenge in clinical practice, imposing a significant burden on both patients and healthcare providers. Studies have reported that nurses' preventive attitudes toward IAD significantly influence its prevalence, and there may be a potential association between achievement motivation and these attitudes. Previous research on nurses' preventive attitudes toward IAD has primarily focused on overall levels, overlooking potential heterogeneity within the population. This study aimed to investigate the heterogeneity in clinical nurses' preventive attitudes toward IAD using a person-centered approach and to identify the influencing factors for different subgroups. A secondary aim was to utilize Self-Determination Theory (SDT) to elucidate the relationship between the identified attitude profiles and nurses' achievement motivation, thereby providing targeted strategies to enhance their preventive attitudes. This study selected 1058 clinical nurses from a tertiary hospital in Fujian, China, as research participants from September to October 2024. The study utilized the following instruments: a general information questionnaire, the Attitude Toward the Prevention of Incontinence-Associated Dermatitis Instrument, and the Achievement Motivation Scale. Latent profile analysis (LPA) was employed to identify the latent profiles of nurses' attitudes toward IAD prevention. At the same time, Two subgroups of nurses' attitudes toward IAD prevention were identified: the low-level group (63.42%) and the high-level, low-personal-responsibility group (36.57%). A significant correlation was found between nurses' attitudes toward IAD prevention and achievement motivation. Nurses with a more positive preventive attitude scored higher on the motivation for success dimension, while those with a less positive attitude scored higher on the motivation to avoid failure dimension. Factors influencing nurses' attitudes toward IAD prevention included position, department, number of participants in wound/ostomy/incontinence care training, satisfaction with the work atmosphere, and achievement motivation scores. This study revealed heterogeneity in nurses' attitudes toward IAD prevention. Nurses with positive attitudes tended to adopt a success-driven approach, while those with relatively negative attitudes leaned toward a failure-avoidance strategy, reflecting two fundamentally distinct coping mechanisms. Nursing managers should address these individual differences by targeting achievement motivation as an intervention point. Management strategies should be tailored to the distinct profiles; for instance, interventions for the "low-level group" should prioritize building competence through structured training, while strategies for the "high-level, low-personal-responsibility group" should focus on enhancing autonomy and personal accountability. By adopting such targeted approaches, managers can more effectively enhance nurses' preventive attitudes, thereby improving care quality and reducing IAD incidence. Show less

Patients with maintenance hemodialysis (MHD) present endothelial dysfunction (ED), which is characterized by impaired vasodilation and a pro-inflammatory state. Lipoprotein(a) (Lp(a)) has pro-inflammatory and pro-atherogenic properties. No study has investigated the association between serum Lp(a) and ED in patients with MHD. This study was conducted to address this issue. We collected serum specimens from 123 fasting MHD patients. The endothelial function was measured using the vascular reactivity index (VRI) determined by digital thermal monitoring, and VRI values of ≥ 2.0, 1.0 to <2.0, and < 1.0, indicated good, intermediate, and poor vascular reactivity, respectively. Lp(a) levels were measured by enzyme-linked immunosorbent assay. Of the 123 MHD patients, 54 (43.9%) had good VRI, 51 (41.5%) had intermediate VRI, and 18 (14.6%) had poor VRI. Serum Lp(a) levels ( The serum Lp(a) level had a negative correlation with the VRI, and it may serve as a potential biomarker for early detection of ED in MHD patients. Show less

Lung cancer imposes a significant financial burden, including psychological financial hardship (PFH). This study aims to identify latent profiles of PFH in lung cancer patients and determine associated patient and caregiver factors. A cross-sectional analysis was conducted with 305 lung cancer patient-caregiver dyads. PFH was measured using the Comprehensive Score for Financial Toxicity (COST), while quality of life (QoL) and distress were also assessed. Latent Profile Analysis (LPA) identified PFH profiles, and one-way ANOVA examined their associations with QoL and distress. Multinomial logistic regression examined correlates of PFH profiles. Three PFH profiles were identified: high-level (COST 0-13), low-level (COST 14-29), and no PFH (COST 30-44). These profiles had medium effects on mental QoL (η Distinct PFH profiles and correlates were identified, highlighting the role of both patient and caregiver factors. Findings underscore the importance of early screening and family-centred interventions to mitigate financial hardship and support well-being in cancer care. Show less

The mediation effect of 24-hour physical activities on the association between type 2 diabetes and mortality is unclear. Additionally, Little evidence was found on the isotemporal substitution effect of 24-hour physical activities components on changing Life expectancy among patients with type 2 diabetes diagnosed. To address the abovementioned research gap, the study has a two-fold aims: first, to examine the mediation effect of 24-hour physical activities in type 2 diabetes and mortality; and second, to address how reallocating time on different daily activities would affect life expectancy. Analysis was conducted on the accelerometer data of 103,359 participants in the UK Biobank, with a median age of 57 years (range 39 to 70). Compositional mediation cox model was conducted to analyze the mediating effects of 24-hour physical activities. Additionally, the cohort Life table method was utilized to estimate the changes of Life-years over the next 10 years resulting from the substitution effect of different physical activities. During a mean follow-up of 13.95 (range 2.95-16.28) years, 2,649 deaths were recorded. Diabetes was significantly associated with increased time spent engaging in sedentary behavior (SB), and reduced time spent on moderate-to-vigorous physical activity (MVPA) and light-intensive physical activity (LPA), thereby demonstrating an association with higher mortality risk. The indirect effect of physical activity (HR = 1.27, 95% CI 1.23-1.30) accounted for 41.9% of the total effect of diabetes on mortality. Furthermore, the Life expectancy gains with a maximum of 1.32 years over the next 10 years was found when reallocating SB time to MVPA. The results revealed that 24-hour physical activities might mediate the association between diabetes and mortality. Therefore, promoting participation in MVPA and reducing sedentary activities among diabetes patients was expected to have a positive effect on Life expectancy over the next 10 years. Show less

Cancer-related fatigue (CRF) is a multifaceted and subjective phenomenon that significantly impacts patients on physical, emotional, and mental levels. This study aims to identify specific subtypes of Cancer-related fatigue (CRF) in patients with Hepatocellular Carcinoma (HCC) and to explore the factors influencing each subtype. This cross-sectional study enrolled 220 participants from a tertiary cancer hospital. Latent Profile Analysis (LPA) and multinomial logistic regression were conducted to identify distinct fatigue profiles and to explore the influencing factors for different categories of CRF among the patients. The analysis revealed three potential categories of CRF severity: Physical balance -Low fatigue (20.1%); Physical imbalance -Moderate fatigue (69.6%); and Physical prominent -High fatigue (10.2%). It was found that the severe insomnia the greater the probability of patients belonging to the Physical prominent -High fatigue (OR = 1.299, 95%CI: 1.188-1.419). Has partner (OR = 5.171, 95%CI: 1.739-15.377), the severe financial stress (OR = 2.570, 95%CI: 1.209-5.463) and the moderate ISI (OR = 1.212, 95%CI: 1.136-1.292) were associated with the Physical imbalance - Moderate fatigue group. Protective factors for the Physical balance - Low fatigue group included higher scores in the physical activity Index (OR = 0.930, 95%CI: 0.870-0.995), Hope Index (OR = 0.647, 95%CI: 0.552-0.758), General self-efficacy (OR = 0.874, 95%CI: 0.793-0.965), Body Mass Index (OR = 0.799, 95%CI: 0.552-0.758), and Child-Pugh A classification (OR = 0.310, 95%CI: 0.119-0.808). CRF in patients with HCC demonstrates significant heterogeneity. It is conducive to the clinical identification of CRF risk characteristics and the design of personalized intervention measures.

Colorectal cancer (CRC) constitutes a significant public health burden in both China and the United States of America (USA), with low physical activity (LPA) identified as a key modifiable risk factor. This study aimed to characterize temporal trends in CRC burden attributable to LPA in these 2 nations from 1990 to 2021. Using data from the 2021 global burden of disease database, age and sex-specific disparities in CRC burden attributed to LPA were evaluated in both countries. Trend analyses of age-standardized mortality rates and age-standardized disability-adjusted life year rates were performed using joinpoint regression. Decomposition analysis was applied to disentangle contributions from demographic aging, population growth, and epidemiological transitions. The age-period-cohort model was employed to quantify the independent effects of age, period, and birth cohort. Bayesian age-period-cohort modeling was utilized to project future CRC burden attributed to LPA through 2036. In 2021, LPA-attributable CRC mortality cases in China reached 16,698 (95% uncertainty interval: 10,065-24,626), exhibiting a 191.16% increase from 1990. The number of disability-adjusted life years attributed to LPA totaled 3,20,464 (95% uncertainty interval: 1,92,275-4,74,070), reflecting a 149.67% rise over the same period. Conversely, the USA reported more moderate increases of 18.26% in LPA-attributable CRC deaths and 20.28% in disability-adjusted life years. The age-period-cohort model revealed that the disease burden in both countries is shifting towards younger age groups. Further analysis of each state in the USA revealed that in 2021, the burden on low-income groups was heavier. The Bayesian age-period-cohort model predicts that the burden of CRC caused by LPA in the 2 countries will show a significant upward trend by 2036. As the burden of CRC caused by LPA becomes increasingly severe in China and the USA, there is an urgent need to raise public awareness about how physical activity can help prevent CRC and for policymakers to create targeted public health policies to lower this disease burden.

This study aims to investigate the effect and mechanism of naringin on anti-osteoporosis by regulating lipid-bone balance. Thirty healthy female SD rats(8-week-old, SPF grade) were selected and randomly divided into a sham group, an ovariectomy group, and a naringin group. Except for the sham group, postmenopausal osteoporosis models were established for both the ovariectomy group and the naringin group by removing bilateral ovaries. Rats in the naringin group were given a naringin suspension at a dose of 100 mg·kg~(-1), while those in sham and ovariectomy groups were administered an equivalent volume of saline. Following the treatment once daily for 12 weeks, an enzyme-linked immunosorbent assay(ELISA) was used to detect the changes in the content of serum estradiol(E₂₎ and bone metabolism biomarkers, including procollagen type Ⅰ N-terminal propeptide(PINP), osteocalcin(OC), and tartrate-resistant acid phosphatase 5(TRACP5). Micro-CT analysis was performed to assess structural alterations in the femoral trabeculae of rats and analyze morphometric parameters of the bone. Hematoxylin-eosin(HE) and Masson staining were used to observe the histopathological changes in the bone tissue. Western blot was employed to analyze the protein expression level of osteogenesis-and adipogenesis-related factors, including peroxisome proliferator-activated receptor gamma(PPARγ), lipoprotein lipase(LPL), RUNT-related transcription factor 2(RUNX2), osterix(OSX), farnesoid X receptor(FXR), and fibroblast growth factor 19(FGF19). Additionally, immunohistochemistry was employed to evaluate the expression of key metabolic pathway proteins FXR and FGF19. After 12-week treatment, compared with the sham group, the ovariectomy group exhibited a significantly reduced level of serum E₂, PINP, and OC, alongside significantly elevated TRACP5. Compared with the ovariectomy group, the levels of serum E₂, PINP, and OC in the naringin group were significantly increased, while the level of TRACP5 was significantly decreased. Compared with the sham group, the ovariectomy group exhibited a decrease in trabecular number and continuity, sparse and disorganized arrangements, and partial formation of voids. The group also showed decreased bone mineral density(BMD), bone volume fraction(BV/TV), trabecular number(Tb.N), and trabecular thickness(Tb.Th), coupled with increased trabecular separation(Tb.Sp). Compared with the ovariectomy group, naringin intervention resulted in improved bone microarchitecture, characterized by increased trabecular number and continuity, more compact arrangements, and a significant reduction in voids. Quantitatively, this was reflected in elevated levels of BMD, BV/TV, Tb.N, and Tb.Th, alongside a significant decrease in Tb.Sp. Under light microscopy, fragmented trabeculae, uneven collagen staining, disorganized arrangements, and an expanded number and size of marrow adipocyte vacuoles were observed in the ovariectomy group, whereas naringin administration attenuated these pathological alterations. Compared with the sham group, the ovariectomy group showed a significant increase in the expression of adipogenic proteins PPARγ and LPL, alongside significant decreases in the expression of osteogenic proteins(RUNX2 and OSX) and of FXR and FGF19 proteins. In contrast, the naringin group exhibited a reversal of these trends compared to the ovariectomy group, with decreased PPARγ and LPL expression and increased RUNX2, OSX, FXR, and FGF19 expression. These findings demonstrate that naringin modulates lipid-bone metabolism homeostasis in postmenopausal osteoporotic rats, ameliorating trabecular microstructure and attenuating bone marrow adipogenesis, with its therapeutic effects mechanistically linked to the FXR/FGF19 signaling pathway.

This study focuses on the impacts of polystyrene/polylactic acid microplastics (PS/PLA-MPs) on ovarian reserve and oocyte maturation in female mice, along with the underlying mechanisms. 1 μm PS-MPs and PLA-MPs were prepared, with PLA-MPs having a rougher surface and broader size distribution. In vitro, PLA-MPs showed higher cytotoxicity to granulosa cells compared to PS-MPs. In vivo, MPs exposure disrupted the estrous cycle, and damaged ovarian reserve. Granulosa cell apoptosis and cytokine activation led to transzonal projection retraction, oocyte oxidative stress, meiotic abnormalities, and reduced oocyte retrieval and polar body extrusion rate, thus reducing litter size. PS-MPs induced more severe intestinal and ovarian impairment. Analysis of feces 16S rRNA, serum metabolomics, and ovarian RNA sequencing revealed that lipoprotein lipase (LPL) was suppressed by both MPs, linking gut microbiota, lipid metabolism, and ovarian injury. Fecal microbiota transplantation as a rescue strategy in MPs exposed mice upregulated LPL, alleviating ovarian reserve decline. In PLA-MPs exposed mice, ovarian reserve related indicators partially recovered after a two-week exposure cessation. These results clarify the similarities and differences in how PS-MPs and PLA-MPs impair ovarian function via gut-ovary axis and lipid metabolism dysregulation. Show less

The relationship between high-density lipoprotein (HDL) and atherosclerotic risk remains incompletely elucidated, potentially due to the inherent heterogeneity of HDL particles. Hypertriglyceridemia is associated with alterations in HDL composition. This study investigated the impact of elevated triglycerides (TG) on HDL and its association with coronary artery disease (CAD) risk using a large prospective cohort study and Mendelian randomization (MR). We found that elevated TG was associated with reduced HDL particle size, decreased concentrations of HDL components, and increased triglycerides in HDL (HDL-TG) (all P for trend < 0.001). The protective effects of HDL particle concentration and HDL cholesterol on CAD are attenuated with increasing serum TG levels. An independent and positive association between HDL-TG levels and incident CAD events (hazard ratio [HR] per 1 standard deviation increase: 1.066, 95% CI: 1.052-1.080, P < 0.001) was confirmed even after adjustment for established cardiovascular disease risk factors. MR analyses supported a causal role for HDL-TG in CAD development (inverse-variance weighted [IVW] method: odds ratios [ORs] of 1.120 (95% CI: 1.053-1.192, P < 0.001) and 1.141 (95% CI: 1.032-1.263, P = 0.010) for dataset groups 1 and 2, respectively). Drug-target MR analyses suggested a potential association between omega-3 fatty acids (OM3-FA) and lower HDL-TG levels, with LPL and DGAT2 as key pharmacological targets. Our findings suggest that elevated TG contributes to adverse alterations in HDL, elevating CAD risk. HDL-TG is an independent positive risk factor for CAD and a potential causal contributor to CAD development. OM3-FA supplementation may offer a therapeutic strategy for mitigating the CAD risk associated with elevated HDL-TG. Show less

Long-persistent luminescence (LPL) materials have applications from safety signage to bioimaging; however, existing organic LPL (OLPL) systems do not align with human scotopic vision, which is sensitive to blue light. We present a strategy to blueshift the emissions in binary OLPL systems by upconverting the charge-transfer (CT) to a locally excited (LE) singlet state. Through rigorous steady-state and time-resolved photoluminescence spectroscopy and wavelength-resolved thermoluminescence measurements, we provide the direct experimental evidence for this upconversion in OLPL systems featuring small energy offsets between the lowest-energy CT and LE singlet states. These systems exhibited strong room temperature LPL, particularly when extrinsic electron traps are added. Importantly, the developed OLPL system achieved Class A (ISO 17398) LPL, matching well with human scotopic vision. The findings not only elucidate the role of small energy offsets in modulating LPL but also provide potential avenues for enhancing the efficiency and applicability of OLPL materials. Show less

Although the incidence of fatty liver disease (FLD) is increasing worldwide, the genetic basis of this disease is not fully understood. This study uses the fatty liver index (FLI) to identify and compare genetic variants associated with FLD in Taiwanese and European populations. In this study, a total of 145,356 Taiwan Biobank participants were included in the discovery analysis. Subjects with elevated FLI were found to have a significantly greater risk of developing FLD, as confirmed by imaging data (OR: 4.43; 95% CI: 3.88-5.06). Through genome-wide association studies (GWAS), we identified 6 variants previously associated with nonalcoholic fatty liver disease (NAFLD) and validated 50 shared risk variants located in ZPR1 and FTO between the Taiwanese and European populations. Conditional analysis of 423 significant variants from FLI-defined FLD further revealed 16 independent variants within 14 genes. Pathway analysis of GWAS significant genes revealed that lipid metabolism and the peroxisome proliferator-activated receptor (PPAR) signaling pathway are causes of hepatic fat accumulation. This study identified six independent NAFLD-associated variants in GCKR, LPL, TRIB1AL, and FTO and emphasized ZPR1 and FTO as shared risk genes for FLI-defined FLD in both Taiwanese and European populations. These findings support the utility of the FLI for FLD prediction, provide new genetic insights, and reveal the common genetic pathways of FLD across two ethnic groups. This research offers a valuable framework for advancing personalized medicine and therapeutic strategies for FLD. Show less

There has been remarkable progress over the past 80 years since Jan Waldenstrom first described patients with a hyperviscosity syndrome related to IgM paraprotein in 1944. The definition of Waldenstrom macroglobulinemia (WM) has evolved from a clinical syndrome to a distinct clinicopathologic entity with characteristic morphology, immunophenotype and molecular features. The landmark discovery of MYD88 mutation among most WM cases in 2012 marked the dawning of an era of molecular genomic exploration that led to a paradigm shift in clinical practice. In the current World Health Organization (WHO) classification of hematologic neoplasms, WM is included in the category of lymphoplasmacytic lymphoma (LPL) of which WM represents over 90% of cases. LPL/WM is also better defined, resolving ambiguity in many cases that would have been classified as "low-grade B-cell lymphoma with plasmacytic differentiation" a decade before. Nevertheless, challenges still face pathologists because criteria for distinguishing LPL/WM from other types of low-grade B-cell lymphoma, particularly marginal zone lymphoma (MZL), remain imperfect.

Triglyceride (TG)/HDL-C ratio (THR) is a surrogate predictor of hyperinsulinemia. To identify novel genetic loci for THR change over time (ΔTHR), we conducted genome-wide association study (GWAS) and genome-wide linkage scan (GWLS) among nondiabetic Europeans from the Long Life Family Study (n = 1,384). Subjects with diabetes or on dyslipidemia medications were excluded. ΔTHR was derived using growth curve modeling and adjusted for age, sex, field centers, and principal components. GWAS used a linear mixed model accounting for familial relatedness. GWLS employed haplotype-based identity-by-descent estimation with 0.5 cM average spacing. Heritability of ΔTHR was moderate (46%). Our GWAS identified a significant locus at the LPL (P = 1.58e-9) for ΔTHR; this locus has been reported before influencing baseline THR levels. Our GWLS found significant linkage with a logarithm of the odds exceeding 3 on 3q28 (logarithm of the odds = 4.1). Using a subset of 25 linkage-enriched families, we assessed sequence elements under 3q28 and identified two novel variants (EIF4A2 [eukaryotic translation initiation factor 4A2]/ADIPOQ-rs114108468, p = 5e-6, minor allele frequency = 1.8%; TPRG1-rs16864075, p = 3e-6, minor allele frequency = 8%; accounted for ∼28% and ∼29% of the linkage, respectively). While the former variant was associated with EIF4A2 (p = 7e-5)/ADIPOQ (P = 3.49e-2) transcriptional levels, the latter variant was not associated with TPRG1 (P = 0.23) transcriptional levels. Replication in the Framingham Heart Study Offspring Cohort observed modest effect of these loci on ΔTHR. Our approach discovered two novel gene variants EIF4A2/ADIPOQ-rs114108468 and TPRG1-rs16864075 on 3q28 for ΔTHR among subjects without diabetes. Our findings provided novel insights into the molecular regulation of insulin resistance. Show less

The aim of this study was to obtain goat CRTC2 gene sequence and elucidate its biological properties, and further study the impact of overexpression and interference of CRTC2 on the cell differentiation of goat subcutaneous precursor adipocytes. The sequence of goat CRTC2 was cloned by reverse transcription (RT)-polymerase chain reaction (PCR) and its molecular characterization was analyzed. The expression of CRTC2 gene in goat tissues and subcutaneous precursor adipocytes differentiated from 0 to 120 h was examined by quantitative real-time PCR (qRT-PCR). The effects of CRTC2 on the subcutaneous precursor adipocyte differentiation were investigated by using liposome transfection, Bodipy, Oil Red O staining and qPCR. The results showed that the cloned goat CRTC2 gene was 2363 bp long (coding sequence [CDS] 2082 bp), encoding 693 amino acids. The relative expression levels of CRTC2 gene were highest in liver and then in kidney (p<0.05). During differentiation, the highest expression of CRTC2 in subcutaneous precursor adipocytes was observed at 120 of differentiating (p<0.01). In addition, we found that overexpression of CRTC2 significantly increased the expression of lipid metabolism-related genes (C/EBPα, C/EBPβ, PPARγ, DGAT1, DGAT2, ACC, FASN, SREBP1, AP2, LPL, ATGL) and promoted lipid accumulation. We then chemically synthesized goat CRTC2 small interfering RNA and transfected it into goat subcutaneous precursor adipocytes. The results revealed that SiRNA-mediated interference with CRTC2 significantly inhibited its differentiation and suppressed lipid droplet aggregation. So, this study indicates that CRTC2 is a positive regulator that promoting cell differentiation of subcutaneous adipocyte in goats, which lays the foundation for an in-depth study of the role of CRTC2 in lipid deposition in goats.

Microtubule-actin cross-linking factor 1 (MACF1), also known as actin cross-linking family protein 7 (ACF7), is a giant cytolinker protein with multiple conserved domains that can orchestrate cytoskeletal networks of actin and microtubules. MACF1 is involved in various biological processes, including cell polarity, cell-cell connection, cell proliferation, migration, vesicle transport, signal transduction, and neuronal development. In this review, we updated the physiological and pathological roles of MACF1, highlighting the components and signaling pathways involved. Novel evidence showed that MACF1 is involved in diverse human diseases, including multiple neuronal diseases, congenital myasthenic syndrome, premature ovarian insufficiency, spectraplakinopathy, osteoporosis, proliferative diabetic retinopathy, and various types of cancer. We also reviewed the physiological roles of MACF1, including its involvement in adhesome formation, bone formation, neuronal aging, and tooth development. In addition, MACF1 plays other roles, functioning as a biomarker for the prediction of infections in patients with burns and as a marker for genome selection breeding. These studies reinforce the idea that MACF1 is a bona fide versatile, multifaceted giant protein. Identifying additional MACF1 functions would finally help with the treatment of diseases caused by MACF1 defects. Show less

To evaluate potential genetic causal relationships between chronic pain subtypes like migraine and multi-site chronic pain (MCP) and their impact on breast cancer occurrence and survival rates. The association between chronic pain and breast cancer was reported before, yet the causal nature between them remained uncertain. Data on chronic pain and breast cancer were sourced from publicly available European genome-wide association study (GWAS) datasets. Genetic association between chronic pain and breast cancer phenotypes was assessed using linkage disequilibrium genetic correlation (LDSC). Colocalization analysis further identified potential shared causal variation. Based on Inverse variance weighted method, 2-sample Mendelian Randomization (MR) was conducted to investigate causal associations between migraine, MCP, and breast cancer or breast cancer survival. Sensitive analysis was conducted to ensure the absence of heterogeneity and horizontal pleiotropy. LDSC demonstrated significant genetic correlations between migraine and both estrogen receptor-negative (ER-) and overall breast cancer, while also revealing a notable genetic association between MCP and ER- and ER+ breast cancer, as well as overall breast cancer. Through colocalization analysis, potential involvement of rs2183271, located in MLLT10 gene, in regulating MCP and ER+ breast cancer was identified. MR analysis revealed the association between migraine and elevated risk of ER- breast cancer (IVW, P = 4.95 × 10 Our results provided new insights into the role of migraine and MCP in breast cancer, paving the way for targeted preventive strategies and future investigations.

The deficiency of fructose-1,6-bisphosphatase 1 (FBP1), a key enzyme of gluconeogenesis, causes fatty liver. However, its underlying mechanism and physiological significance are not fully understood. Here we demonstrate that carbohydrate response element-binding protein (ChREBP) mediates lipid metabolic remodeling and promotes progressive triglyceride accumulation against metabolic injury in adult FBP1-deficient liver. Inducible liver-specific deletion of Fbp1 gene caused progressive hepatomegaly and hepatic steatosis, with a marked increase in hepatic de novo lipogenesis (DNL) as well as a decrease in plasma β-hydroxybutyrate levels. Notably, FBP1 deficiency resulted in a persistent activation of ChREBP and its target genes involved in glycolysis, lipogenesis, and fatty acid oxidation, even under fasting conditions. Furthermore, liver-specific ChREBP disruption could markedly restore the phenotypes of enhanced DNL and triglyceride accumulation in FBP1-deficient liver but exacerbated its hepatomegaly and liver injury, which was associated with remarkable energy deficit, impaired mammalian target of rapamycin (mTOR) activation, and increased oxidative stress. Furthermore, metabolomics analysis revealed a robust elevation of phosphoenolpyruvate, phosphoglycerates, phospholipids, and ceramides caused by ChREBP deletion in FBP1-deficient liver. Put together, these results suggest that overactivation of ChREBP pathway mediates liver metabolic remodeling in the absence of FBP1, which contributes to the pathogenesis of progressive hepatic steatosis and provides a protection against liver injury. Thus, our findings point to a beneficial role of ChREBP in metabolic remodeling in the context of excessive gluconeogenic intermediates. Show less

Glucose can activate the carbohydrate response element binding protein (ChREBP) transcription factor to control gene expressions in the metabolic pathways. The way of ChREBP involvement in human prostate cancer development remains undetermined. This study examined the interactions between prostate fibroblasts and cancer cells under the influences of ChREBP. Results showed that high glucose (30 mM) increased the phosphorylation of AKT at S473 and AMP-activated protein kinase (AMPK) at S485 in human prostate fibroblast (HPrF) cells and prostate cancer PC-3 cells. High glucose enhanced the expression of ChREBP, which increased the expressions of fibronectin, alpha-smooth muscle actin (α-SMA), and WNT1 inducible signaling pathway protein 1 (WISP1), magnifying the cell growth and contraction in HPrF cells in vitro. The cell proliferation, invasion, and tumor growth in prostate cancer PC-3 cells were enhanced by inducing the expressions of ChREBP, mucosa-associated lymphoid tissue 1 (MALT1), and epithelial-mesenchymal transition markers with high glucose treatment. Moreover, ectopic ChREBP overexpression induced NF-κB signaling activities via upregulating MALT1 expression in PC-3 cells. Our findings illustrated that ChREBP is an oncogene in the human prostate. High glucose condition induces a glucose/ChREBP/MALT1/NF-κB axis which links the glucose metabolism to the NF-κB activation in prostate cancer cells, and a glucose/ChREBP/WISP1 axis mediating autocrine and paracrine signaling between fibroblasts and cancer cells to promote cell migration, contraction, growth, and invasion of the human prostate.

Sudden cardiac arrest (SCA) is a leading cause of death in pediatric hypertrophic cardiomyopathy (HCM). The study sought to analyze the clinical and genetic characteristics of pediatric HCM and assess the applicability of current SCA risk prediction models. We enrolled individuals diagnosed as HCM before 20 years of age, between 2000 and 2020, excluding those secondary to hemodynamic causes and those associated with genetic syndromes other than RASopathies. Among 91 patients (31 female, 60 male), SCA occurred in 13 (14.3%) patients, with 6 (46%) cases presenting as the initial symptom. These 6 patients were older and had lower left ventricular mass In pediatric HCM, SCA is notably associated with sarcomere gene pathogenic variants. While newer risk scoring systems, if incorporated with genetic information, effectively predict SCA in this Asia cohort, a challenge remains: nearly half of SCA cases present as the initial clinical manifestation.

Heart failure (HF) as the terminal stage of various cardiac diseases, its underlying molecular mechanisms still remain elusive. Emerging evidence have implicated long noncoding RNAs (lncRNAs) play a multifaceted role in the progression of cardiac hypertrophy and HF. Here, it is identified that a lncRNA forkhead box O6, opposite strand (Foxo6os) is significantly downregulated in murine HF model induced using transverse aortic constriction (TAC). Knockdown of Foxo6os accelerates cardiomyocyte hypertrophy, reflects as elevated expression of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and myosin heavy chain 7 (MYH7). Conversely, Foxo6os overexpression can improve cardiac function and alleviate adverse cardiac remodeling. Mechanistically, Foxo6os directly interacts with myosin-binding protein-C (MYBPC3), which then recruits protein kinase C alpha (PKC-α) to facilitate MYBPC3 phosphorylation, resulting in maintaining myocardial contractility and postponing HF progression. Therefore, these findings underscore the critical role of Foxo6os in preserving cardiomyocyte contractile function, suggesting a potential for Foxo6os as a novel therapeutic target of HF. Show less

Individuals with diabetes are susceptible to cardiac dysfunction and heart failure, potentially resulting in mortality. Metabolic disorders frequently occur in patients with diabetes, and diabetes usually leads to remodeling of heart structure and cardiac dysfunction. However, the contribution and underlying mechanisms of metabolic and structural coupling in diabetic cardiac dysfunction remain elusive. Two mouse models of type 2 diabetes (T2DM) were used to assess alterations in glucose/lipid metabolism and cardiac structure. The potential metabolic-structural coupling molecule ACBP (acyl-coenzyme A-binding protein) was screened from 4 published datasets of T2DM-associated heart disease. In vivo loss-of-function and gain-of-function approaches were used to investigate the role of ACBP in diabetic cardiac dysfunction. The underlying mechanisms of metabolic and structural coupling were investigated by stable-isotope tracing metabolomics, coimmunoprecipitation coupled with mass spectrometry, and chromatin immunoprecipitation sequencing. Diabetic mouse hearts exhibit enhanced lipid metabolism and impaired ultrastructure with marked cardiac systolic and diastolic dysfunction. Analysis of 4 T2DM public datasets revealed that Our findings demonstrated that ACBP mediates the bidirectional regulation of cardiomyocyte metabolic and structural associations and identified a promising therapeutic target for ameliorating cardiac dysfunction in patients with T2DM.

Hypertrophic cardiomyopathy (HCM) affects approximately 600,000 people in the United States. Loss-of-function mutations in Myosin Binding Protein C3, MYBPC3, are the most common genetic cause of HCM, with the majority of mutations resulting in haploinsufficiency. To restore cardiac MYBPC3, we use an adeno-associated virus (AAV9) vector and engineer an optimized expression cassette with a minimal promoter and cis-regulatory elements (TN-201) to enhance packaging efficiency and cardiomyocyte expression. Rather than simply preventing cardiac dysfunction preclinically, we demonstrate in a symptomatic MYBPC3-deficient murine model the ability of AAV gene therapy to reverse cardiac hypertrophy and systolic dysfunction, improve diastolic dysfunction, and prolong survival. Dose-ranging efficacy studies exhibit restoration of wild-type MYBPC3 protein levels and saturation of cardiac improvement at the clinically relevant dose of 3E13 vg/kg, outperforming a previously published construct. These findings suggest that TN-201 may offer therapeutic benefits in MYBPC3-associated cardiomyopathy, pending further validation in clinical settings. Show less

Females with hypertrophic cardiomyopathy present at a more advanced stage of the disease and have a higher risk of heart failure and death. The factors behind these differences are unclear. We aimed to investigate sex-related differences in clinical and genetic factors affecting adverse outcomes in the Sarcomeric Human Cardiomyopathy Registry. Cox proportional hazard models were fit with a sex interaction term to determine if significant sex differences existed in the association between risk factors and outcomes. Models were fit separately for females and males to find the sex-specific hazard ratio (HR). After a mean follow-up of 6.4 years, females had a higher risk of heart failure (HR, 1.51 [95% CI, 1.21-1.88]; We found that clinical and genetic factors contributing to adverse outcomes in hypertrophic cardiomyopathy affect females and males differently. Thus, research to inform sex-specific management of hypertrophic cardiomyopathy could improve outcomes for both sexes. Show less

To broaden our understanding of bradyarrhythmias and conduction disease, we performed common variant genome-wide association analyses in up to 1.3 million individuals and rare variant burden testing in 460,000 individuals for sinus node dysfunction (SND), distal conduction disease (DCD) and pacemaker (PM) implantation. We identified 13, 31 and 21 common variant loci for SND, DCD and PM, respectively. Four well-known loci (SCN5A/SCN10A, CCDC141, TBX20 and CAMK2D) were shared for SND and DCD, while others were more specific for SND or DCD.
