Precise identification of vulnerable plaque (VAP) is essential for the prevention of acute cardiovascular diseases, yet current molecular probes are hampered by poor VAP lesion penetration and high background. Here, the innate tropism of circulating inflammatory monocytes for VAP, and their differentiation-driven expression of legumain (Lgmn) in response to the VAP microenvironment is exploited. A monocyte differentiation-activated fluorescent (MDAF) probe is conceived that hitchhikes monocytes to precisely migrate to VAP and is activated by Lgmn during monocyte differentiation. This activation triggers in situ self-assembly, resulting in spatiotemporally controlled aggregation-induced emission (AIE) fluorescence signals, and turning the monocyte itself into an on-site "scout" that reports plaque instability.

Dual GIP/GLP-1 receptor agonists have gained significant attention in clinical applications because of their remarkable efficacy in reducing obesity and type 2 diabetes. However, the mechanisms by which these dual agonists affect systemic metabolism remain elusive. To investigate the effects of a novel dual-receptor agonist, THDBH120, on systemic metabolism in obese individuals and the specific roles of GIPR and GLP-1R in modulating systemic and adipose tissue metabolism. To evaluate the intrinsic properties of THDBH120, we conducted a potency assay by using HEK293 cell lines overexpressing either human GIPR or GLP-1R and measured the accumulation of cAMP as a downstream second messenger following receptor activation. To evaluate the efficacy of THDBH120 on systemic metabolism, we used obese rodents and nonhuman primate species that received various doses and frequencies of THDBH120. To determine the metabolic roles of GLP-1R and GIPR in mediating the beneficial effects of THDBH120, we used GLP-1R- and GIPR-knockout mouse models treated with THDBH120, the GLP-1R agonist semaglutide, or the GIPR agonist LAGIPRA and performed transcriptomic sequencing analyses of adipose tissues. THDBH120 is a novel long-acting dual GIPR/GLP-1R agonist that has superior weight loss and metabolic improvement effects in rodents and mammals. The activation of GLP-1R by semaglutide or THDBH120 improved lipid metabolism, whereas the activation of GIPR by LAGIPRA or THDBH120 alleviated inflammation. THDBH120 improved lipid metabolism via GLP-1R-mediated pathways and mitigated inflammation by activating GIPR-associated pathways in the adipose tissues of obese mice. Both GLP-1R and GIPR are important in mediating the beneficial effects of dual receptors on systemic metabolism. THDBH120 is a novel long-acting dual GIPR/GLP-1R agonist that has potential clinical applications. Show less

The bioactive peptide setmelanotide is a validated MC4R agonist, yet its clinical utility is constrained by poor aqueous solubility and dose-limiting, off-target hyperpigmentation. To overcome these dual liabilities, we executed a synergistic optimization strategy guided by detailed SAR investigation. This approach unveiled two critical design principles: a C-terminal "cationic imperative", where lysine uniquely conferred a > 20-fold solubility enhancement while retaining potency, and rational manipulation of the core pharmacophore, which imparted >100-fold selectivity over MC1R/MC3R. This synergy yielded the lead compound SC19, which integrates these features into a balanced profile of sub-nanomolar potency (EC₅₀ = 0.12 nM; pEC₅₀ = 9.93), exceptional selectivity, and high aqueous solubility. In a diet-induced obesity model, SC19 demonstrated robust efficacy comparable to setmelanotide in reducing weight gain and improving lipid profiles, affirming its therapeutic potential. This work not only presents a promising lead compound but also validates a synergistic optimization blueprint for concurrently enhancing the pharmacological and drug-like properties of therapeutic peptides.

Atherosclerotic cardiovascular disease remains the leading cause of global mortality, with hypercholesterolemia serving as a critical driver of atherogenesis. Although current lipid-lowering therapies substantially improve circulating lipid profiles, strategies that provide more durable, safe, and efficient control of lipid metabolism are still needed. Epigenome editing offers a promising approach for long-lasting repression of disease-modifying genes without altering the underlying DNA sequence. Here, we develop CRISPRoff platforms delivered by adeno-associated virus or lipid nanoparticle to epigenetically silence hepatic Hmgcr or Pcsk9 in vivo. In both C57BL/6J wild-type and ApoE Show less

With the rapid progression of global population aging, the incidence of cognitive dysfunction-related disorders is steadily increasing. In recent years, growing attention has been directed toward the interaction between the gut microbiota and the central nervous system (CNS). The gut-brain axis (GBA), as a bidirectional communication pathway, plays an increasingly recognized role in regulating cognitive functions. Ganoderma lucidum polysaccharides (GLP), a traditional medicinal and edible substance, can regulate gut microbiota homeostasis and short-chain fatty acid (SCFAs) levels through the GBA. GLP reduces the Firmicutes/Bacteroidetes ratio, significantly increases the abundance of Lactobacillus, and further suppresses oxidative stress and inflammatory responses by controlling microglial overactivation and neuroinflammation, thereby enhancing the expression of synapse-associated proteins and brain-derived neurotrophic factor (BDNF). Consequently, GLP shows potential for improving cognitive dysfunction. This review systematically summarizes the bioactivities of GLP, explores the neurodegenerative mechanisms of aging, and proposes the possibility that GLP mitigates aging-induced inflammation and improves cognitive function via modulation of the gut microbiota.

Diabetic foot ulcers (DFU) are a severe complication of diabetes. Although dysregulated M2 macrophage polarization is recognized as a key driver of chronic inflammation in DFU, the molecular checkpoints that can be therapeutically targeted to restore M2 bias remain poorly defined. Here, we aimed to determine whether the RNA-binding protein TAF15 acts as a post-transcriptional stabilizer of the M2-promoting CEBPB/APOE/PTX3 axis, thereby accelerating DFU healing. First, we confirmed that APOE positively regulates PTX3, which supports M2 polarization and the proliferation and migration of HDF. CEBPB transcriptionally activated APOE and promoted M2 macrophage polarization. TAF15 stabilized CEBPB mRNA and affected HDF cell proliferation and migration by promoting M2 macrophage polarization. Additionally, TAF15 overexpression partially counteracted the disruption of M2 macrophage polarization caused by APOE silencing and facilitated DFU wound healing. Collectively, our findings establish TAF15-driven stabilization of CEBPB mRNA as a target point that sequentially activates APOE/PTX3 signaling to enforce M2 polarization and accelerate DFU closure. This study provides a preclinical rationale for the development of TAF15-targeted oligonucleotides or small-molecule strategies to reprogram wound macrophages and improve DFU outcomes in patients with diabetes.

Atherosclerosis is a chronic and progressive inflammatory disease that can lead to adverse cardiovascular and cerebrovascular events. Phenotypic switching of vascular smooth muscle cells (VSMCs) plays a pivotal role in its development and progression, but the upstream regulatory mechanisms remain incompletely defined. Here, we identify ubiquitin-fold modifier 1 (UFM1), a ubiquitin-like protein, as a critical regulator of VSMCs plasticity and atherogenesis. In VSMCs stimulated with oxidized low-density lipoprotein (ox-LDL), UFM1 overexpression markedly attenuated phenotypic switching, restoring contractile features and suppressing synthetic activation, accompanied by reduced proliferation and migration. In contrast, UFM1 knockdown further exacerbated these phenotypic alterations. In ApoE Show less

Norethindrone (NET) and levonorgestrel (LNG) are synthetic progestins frequently detected in aquatic environments, have unclear effects on lipid metabolic homeostasis during the early life stages of aquatic organisms. Although progestins commonly occur as mixtures, their combined impacts remain unclear. In this study, we investigated the individual and combined impacts of NET and LNG at environmentally relevant concentrations (2-200 ng/L) on lipid metabolism in zebrafish larvae. NET and LNG significantly disrupted early development in zebrafish. It also altered lipid profiles, as indicated by elevated triglyceride (TG) levels, reduced total cholesterol (TC), as well as alterations in key metabolic enzymes (FASN, LPL) and lipid-regulatory genes (pparγ, fasn, lpl, pparα). Co-exposure with LNG resulted in non-additive responses across multiple endpoints. Antagonistic interactions were predominant at medium and high concentrations, while occasional synergism was observed at low doses. These complex patterns were further supported by Bliss independence model analysis. Notably, combined exposure suppressed both lipid synthesis and degradation pathways more strongly than individual treatments, leading to lipid accumulation and altered energy regulation. This study advanced understanding of the ecological risks caused by progestins in aquatic environments and highlighted the necessity of mixture-based risk assessment of endocrine-disrupting compounds.

In recent years, except for the well-known heart failure with reduced ejection fraction (HFrEF), the incidence of heart failure with preserved ejection fraction (HFpEF) and heart failure with mildly reduced ejection fraction (HFmrEF) among the classification of heart failure (HF) has been increasing. However, due to their complex mechanisms, current research remains insufficient to address clinical needs. Utilizing wild-type (WT), miR-30a-5p knockout (KO), and overexpression (OE) murine models combined with estrogen modulation and ovariectomy (OVX), this study delineates sex-specific regulatory networks in HF pathogenesis. Female KO mice lost the inherent resistance of WT females to HFpEF induction via 24-week HFD/L-NAME, whereas males exhibited comparable HFpEF susceptibility regardless of genotype, developing hallmark phenotypes including diastolic dysfunction (E/E'), myocardial hypertrophy (heart weight/tibia length), cardiac fibrosis, and hepatic steatosis. Particularly, due to the reduced ejection fraction in KO mice, combined with HFD/L-NAME, the HF phenotype was ultimately manifested as impaired diastolic function and slightly reduced ejection fraction (with the characteristics of HFpEF and HFmrEF). Mechanistically, KO-HF females displayed significant estrogen axis disruption (plasma estradiol and the expression of ERα, ERβ, ESRRA, and PELP1 expression). OVX in WT females validated the importance of estrogen for HFpEF resistance. Transcriptomic profiling identified convergent targets across cardiac (ITGAD, ITGAM, FGA, and FGB) and hepatic tissues (APOA1 and APOB), revealing miR-30a-5p's orchestration of extracellular matrix remodeling (via ITGAD/ITGAM mechanotransduction),fibrinogen-mediated microvascular homeostasis, and APOB-driven metabolic dysregulation. Notably, OE intervention failed to mitigate OVX-induced cardiac/hepatic pathology, implicating estrogen-dependent miR-30a-5p functionality. These findings establish miR-30a-5p as a crucial sex-specific regulator of HF (mainly HFpEF), operating through estrogen signaling to balance cardiac compliance and metabolic adaptation. Show less

The neurotrophic factor (NTF) family has recently expanded its role beyond neurological conditions, but its involvement in acute inflammatory lung diseases remains largely unclear. Using well-established acute lung injury (ALI) and sepsis models, we demonstrate that brain-derived neurotrophic factor (BDNF), a key NTF, is impaired in pulmonary epithelial cells and negatively correlates with the inflammatory response. Raising the BDNF level alleviates inflammatory lung injury, but these effects are absent in macrophage-deleted mice. Both in vivo and in vitro results show BDNF inhibits macrophage inflammation, and further proteomics analysis identifies macrophage TLR4 as a receptor that BDNF antagonizes via direct binding. The BDNF fragment (aa 104-115) is critical for BDNF-TLR4 interaction, and the corresponding synthetic BDNF-derived dodecapeptide (BDP-12) retains TLR4-antagonistic and anti-inflammatory effects both in vitro and in vivo, without pro-proliferative side effects. In conclusion, our findings reveal that epithelial-derived BDNF prevents macrophage inflammation by directly targeting TLR4 and highlights BDP-12 as a potential therapeutic agent for acute inflammatory diseases.

To investigate longitudinal changes in neuroimmune biomarkers during acute exacerbations of chronic obstructive pulmonary disease (AECOPD), their modulation by standard therapy, and prognostic implications for 90-day outcomes. In a prospective cohort, 266 hospitalized AECOPD patients were stratified into worsened ( Compared with controls, AECOPD patients exhibited higher IL-6, TNF-α, PD-1, and MMP-9, alongside reduced BDNF and IL-10. Stable patients demonstrated partial biomarker normalization, whereas worsened patients retained a pro-inflammatory profile. Corticosteroids and antibiotics attenuated cytokine elevations, and oxygen therapy facilitated BDNF recovery. Low BDNF and high MMP-9 predicted spirometric decline, while elevated PD-1 and MMP-9 were associated with increased 90-day readmission risk. A dual-axis model incorporating neurotrophic and immune exhaustion markers outperformed GOLD classification for risk prediction. Neuroimmune biomarkers capture recovery heterogeneity in AECOPD. The proposed dual-axis model improves prognostic accuracy and may inform personalized management strategies. Show less

Hemodialysis, as one of the main alternative treatment methods for end-stage renal disease, has received much attention in recent years. Due to the particularity of hemodialysis treatment, patients have a relatively high risk of infection during the treatment process. Hemodialysis nurses, who are the main executors of the treatment operations and have the most contact with patients, have a close relationship with the infection risk of patients. The level of their hospital infection prevention and control literacy is closely related to the infection risk of patients. To explore the current level of knowledge, attitudes, and practices (KAP) of hospital infection prevention and control among haemodialysis nurses in the Sichuan Province, China, and identified their potential categories. This provided evidence-based recommendations for improving infection control management in hemodialysis departments. A cross-sectional study was conducted From July 15 to August 15, 2025 using a convenience sampling method to survey 470 hemodialysis nurses from 78 hospitals in Sichuan Province. Participants were licensed nurses with over 3 months of hemodialysis experience. Data were collected using the A total of 460 valid questionnaires were collected, with an effective response rate of 97.87%. The average scores for knowledge, attitudes, and practices related to hospital infection prevention and control among haemodialysis nurses were 4.67 ± 0.43, 4.59 ± 0.43, and 4.74 ± 0.34, respectively. Three latent profile models were constructed, with the two-class model identified as the optimal solution, which were defined as the "Low KAP Group" (25.9%) and "High KAP Group" (74.1%). Logistic regression analysis revealed that sex, responsibility for infection control, hospital level, annual number of infection control training sessions, organizational support, and work engagement were significant influencing factors ( The KAP level of haemodialysis nurses in hospital infection prevention and control was relatively high. Hospital managers should tailor supportive work environments on the basis of the individual characteristics and work engagement of haemodialysis nurses to improve the KAP level of nosocomial infection prevention and control among haemodialysis nurses.

Aging is asynchronous across cells and organs, but whether plasma proteins can capture cell type-specific aging and predict disease and mortality remains unknown. We developed machine learning models to estimate the biological age of more than 40 distinct cell types-spanning neuronal, immune, glial, endocrine, epithelial, and musculoskeletal origins-using over 7,000 plasma proteins measured in 60,000 individuals across three cohorts, comprising the largest human plasma proteomics aging study to date. Individuals showed heterogeneous aging profiles, with 20-25% exhibiting accelerated aging in a single cell type and 1-3% across ten or more cell types. APOE genotype showed antagonistic aging effects in different cell types: APOE4 carriers exhibited older astrocytes but younger macrophages, while APOE2 carriers showed the inverse. Cellular aging signatures were uniquely associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Amyotrophic lateral sclerosis (ALS) showed the strongest association with skeletal myocyte aging (hazard ratio = 12.7 for extreme accelerated versus youthful aging). In Alzheimer's disease (AD), prevalent cases showed accelerated aging across multiple neural and peripheral cell types, with extreme astrocyte aging conferring AD risk comparable to APOE4 carrier status. Moreover, extreme astrocyte aging increased AD risk in APOE4/4 carriers threefold, while youthful astrocytes strikingly reduced risk. Beyond neurodegeneration, respiratory cell aging identified smokers at 58% higher lung cancer risk, and myeloid aging identified normoglycemic individuals at higher diabetes risk. Both specific cellular vulnerabilities and cumulative aging burden influenced survival, wherein youthful immune or neuronal profiles were protective. A polycellular aging risk score provided robust mortality risk stratification across platforms and cohorts. These findings establish a framework for quantifying biological aging at the cellular resolution using plasma proteomics, revealing heterogeneity in aging trajectories and their impact on disease susceptibility and resilience.

Fusion genes are pivotal drivers of tumorigenesis, often generating oncogenic chimeric RNAs and fusion circular RNAs. However, the mechanisms by which these transcripts synergistically contribute to cancer progression remain poorly understood. Here, we identified a lung cancer-specific chimeric RNA KANSL1-ARL17A (chKANSARL) and its circular variant fusion circular RNA KANSL1-ARL17 A (F-circKA), both derived from the fusion gene KANSARL. Functional assays revealed that overexpression of either chKANSARL or F-circKA significantly enhanced lung cancer cell proliferation, migration, and invasion, while their knockdown suppressed these malignant phenotypes. In vivo experiments demonstrated that chKANSARL overexpression accelerated tumor growth in immunodeficient mice. Notably, coexpression experiments uncovered a synergistic regulatory interaction between F-circKA and chKANSARL, amplifying oncogenic effects. Mechanistically, miRNA sequencing and dual-luciferase assays revealed that F-circKA acts as a molecular sponge for miR-6860, thereby derepressing chKANSARL expression. Rescue experiments further validated this regulatory axis, wherein miR-6860 inhibition reversed the tumor-suppressive effects of F-circKA knockdown. Collectively, our study identifies and characterizes a novel F-circKA/miR-6860/chKANSARL regulatory axis, revealing how dual transcriptional outputs from the KANSARL fusion gene can synergistically drive lung cancer progression. These findings highlight a previously unrecognized layer of cooperative regulation between linear and circular fusion RNAs in oncogenesis and provide a new framework for understanding fusion gene-mediated tumorigenesis.

Given the heterogeneous nature of Alzheimer's disease (AD) and its higher prevalence in females, it is crucial to understand sex-related differences in AD presentation and changes in the brain. This systematic review investigates sex differences in AD and summarizes key findings from neuroimaging studies over the past two decades to examine how genetics, hormones, and lifestyle factors influence neuroimaging biomarkers and their correlation with cognitive decline and AD progression. A comprehensive literature search was conducted across several databases for human studies from 2004 to 2024 related to AD, biological sex differences, and neuroimaging. After a 3-step review process, the final extraction included 120 peer-reviewed studies using various neuroimaging modalities, such as MRI, amyloid-beta PET, tau-PET, and fluorodeoxyglucose (FDG) PET, to investigate sex as a biological predictor variable in adults with or at risk for AD. Over 90% of the reviewed studies identified clear sex-specific patterns of imaging biomarkers related to cognitive reserve, hormonal changes, APOE-ɛ4 genotype, inflammation, vascular health, and lifestyle factors. Machine learning studies increasingly incorporate sex as a key variable, revealing sex-specific biomarkers and improving model performance in predicting disease status and progression. Considering biological sex in AD research is essential for improving diagnostic accuracy, tailoring interventions, and health outcomes. This systematic review identifies sex-specific patterns in neuroimaging biomarkers of AD, influenced by cognitive reserve, hormones, APOE-ɛ4 genotype, inflammation, vascular health, and lifestyle. Recognizing these differences is crucial for understanding, diagnosis, and treatment efficacy. Show less

Occupational stress in nursing is a critical issue that can have significant implications for both workforce stability and personal health. This study aimed to identify subgroups of occupational stress among Chinese female clinical nurses using latent profile analysis, compare sociodemographic differences across these subgroups, and examine their associations with premenstrual syndrome (PMS). A cross-sectional study was conducted among female nurses in tertiary hospitals in Huai'an City, Jiangsu Province, China, from November to December 2023. We recruited participants via convenience sampling, and 400 valid questionnaires were collected. Data were collected using a researcher-developed general information questionnaire, the standardized Chinese Nurses Stressor Scale (35 items), and the Premenstrual Syndrome Scale. Latent profile analysis (LPA) was performed with Mplus 8.0 to identify occupational stress subtypes. Sociodemographic predictors of these subtypes were explored using chi-square tests and multivariate logistic regression in SPSS 25.0. The association between stress subtypes and PMS symptoms was assessed using ANOVA. A Three clinical female nurse occupational stress subtypes were identified: overall low-stress (38.3%, This study identified significant heterogeneity in occupational stress among clinical female nurses, categorized into three distinct subtypes differing in stress levels and demographic characteristics. These findings highlight the importance of considering individual differences when developing interventions to address occupational stress. The study advocates for the implementation of intervention strategies targeting different types of stress in nursing education and organizational reform to better support nurses in fulfilling their responsibilities.

Harnessing the simultaneous activation of GLP-1R, GIPR, and GCGR has emerged as a highly promising therapeutic paradigm for obesity and related metabolic diseases, including nonalcoholic steatohepatitis (NASH). Here, we report the discovery of TPM003, a novel unimolecular GLP-1R/GIPR/GCGR triple agonist engineered by using a long-acting PEG-fatty acid (PEG-FA) stapling technology. TPM003 exhibits balanced triple receptor agonism and demonstrates an extended systemic half-life across multiple species. In obese mice, TPM003 induced robust and durable weight loss, accompanied by broad improvements in metabolic parameters, outperforming current GLP-1RA standards. Importantly, TPM003 also effectively reversed hepatic steatosis and improved markers of liver function in multiple NASH models. Furthermore, TPM003 is compatible with SNAC-based absorption enhancement, enabling oral delivery in a tablet formulation. Collectively, these findings highlight the therapeutic advantages of balanced GLP-1R/GIPR/GCGR agonism for obesity and NASH and support TPM003 as a promising preclinical candidate with translational potential.

Lipoprotein(a) [Lp(a)] is a genetically determined lipoprotein that has been established as an independent and causal risk factor for atherosclerotic cardiovascular disease (ASCVD) and calcific aortic valve disease (CAVD). Structurally composed of a low-density lipoprotein (LDL)-like particle covalently linked to apolipoprotein(a) [apo(a)], Lp(a) exhibits unique atherogenic, thrombogenic, and inflammatory properties, largely due to its role as a carrier of oxidized phospholipids (OxPL). Plasma Lp(a) concentrations are predominantly determined by the number of kringle IV type 2 (KIV-2) repeats in the LPA gene, with minimal influence from lifestyle or environmental factors. Despite substantial evidence linking elevated Lp(a) to cardiovascular risk, clinical testing remains underutilized, especially in East Asian countries. In Taiwan, although population-level Lp(a) concentrations are comparatively low, a significant subset exceeds risk thresholds, with local studies confirming its prognostic value in coronary artery disease and ischemic stroke. Barriers, including limited physician awareness, implementation barriers, and therapeutic nihilism, contribute to its under-recognition. This review highlights the molecular features of Lp(a), its pathogenesis of cardiovascular disorders, epidemiology, and current barriers and future advances in diagnostic testing, with a particular focus on implications for cardiovascular risk management in Taiwan.

Distressing dreams were previously reported to predict future all-cause dementia among predominantly white US participants aged 79-89 years, particularly in men. We investigated whether disturbing dreams (nightmares and bad dreams) were associated with all-cause and Alzheimer dementia (AD) among individuals aged 60-89 years from diverse international regions. Data were from six longitudinal cohort studies across Brazil, China, France, Italy, South Korea, and Taiwan (n = 10,238, 42.5% men). Cox regressions with a random effect for study investigated associations between disturbing dreams and incident dementia, with all participants and stratified separately by sex and baseline age. Analyses examined (i) any disturbing dreams and (ii) disturbing dreams at least once a week. Fully adjusted analyses included three studies with covariates for sleep problems, medications, mental and physical health, cognition, and APOE ε4 status. Disturbing dreams were reported by 24.2% overall and all-cause dementia, and AD incidence was 10.8 and 5.3 per 1000 person-years, respectively. In fully adjusted analyses, having any disturbing dreams was associated with increased incidence of all-cause dementia among 60-69-year-olds (hazard ratio [HR] 3.93, 95% confidence interval [CI] 1.32-11.67). There were no significant effects for older individuals. In fully adjusted sex-stratified analyses, having disturbing dreams at least once a week was associated with AD only among men (HR 3.59, 95% CI 1.44-8.96). We found some evidence for disturbing dreams being associated with incident all-cause dementia among individuals aged 60-69 years and with AD among men. The mechanisms potentially underlying these associations remain to be clarified. Show less

This scoping review aims to map the experiences and outcomes of patients and their families undergoing genetic testing and counseling regarding dementia to inform future research directions and clinical practice. Rigorous scoping review methodology was followed. Ovid Medline, Embase, PsycINFO, and CINAHL were searched with keywords and MeSH terms related to "genetic testing", "genetic counseling", "dementia", "decision making", and "patient outcomes" for peer-reviewed studies with adult participants published over the last ten years. Thirty-six articles met inclusion criteria. Narrative synthesis organized findings into temporal categories including motivations for genetic testing, experiences during the testing/counseling process, and outcomes after testing. Common motivators included reducing uncertainty, reproductive planning, life planning, and the prospect of a treatment becoming available in the future. A lack of current treatments and fear that knowledge of genetic risk would be difficult to cope with were common barriers to testing. Patient-centered communication improved satisfaction. Genetic testing was generally psychologically well tolerated, and a wide range of practical responses were reported including changes to lifestyle, diet, advanced care and financial planning, and engaging in clinical trials. This review maps the experiences and outcomes of genetic testing or counseling for people with or at potentially increased genetic risk of dementia. Genetic testing and counseling for directly causal dementia genes and APOE genotype appears well tolerated but long-term outcome data is lacking. Motivations, concerns and perceived benefits of knowing genetic results vary depending on personal, familial and cultural viewpoints. Genetic counseling can help patients and families prepare, reduce decisional regret, and adapt to results. Motivations varied, and a patient-centered approach addressing both information and psychological aspects improves satisfaction. Future longitudinal research should ascertain ways to support individuals from a wide range of demographics with understanding and adjusting to genetic risk information regarding dementia. Show less

Lecanemab, an anti-amyloid beta (Aβ) protofibril antibody, was introduced in China in 2024, but its real-world performance remains unknown. In this prospective, multicenter study across 21 sites, 261 Alzheimer's disease patients (mild cognitive impairment to moderate dementia) received biweekly lecanemab (10 mg/kg). A matched Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort served as comparator. Cognitive tests, plasma biomarkers, and optional amyloid/tau positron emission tomography (PET) were assessed over 6 months. Lecanemab significantly attenuated cognitive decline versus ADNI. Plasma Aβ42, Aβ40, phosphorylated tau 217 (p‑tau217), glial fibrillary acidic protein (GFAP), and ratios showed robust changes; a p‑tau217 reduction correlated with amyloid PET clearance (mean -22.1 Centiloid; 29.2% turned amyloid-negative). Apolipoprotein E (APOE) ε4 non-carriers showed greater improvements. Infusion reactions occurred in 11.1% and amyloid-related imaging abnormalities in 9.2% (1.6% symptomatic), with no stage-related safety differences. Lecanemab was effective and well tolerated in real-world Chinese patients. Plasma p‑tau217 may serve as a sensitive, minimally invasive treatment-response biomarker. Show less

This study investigated longitudinal plasma serotonin dynamics across the Alzheimer's disease (AD) continuum (cognitively normal [CN], mild cognitive impairment [MCI], and AD) to determine whether baseline serotonin and its 24-month change are associated with CSF amyloid-β (Aβ42), tau biomarkers, amyloid PET burden, structural brain integrity, and cognitive decline. Data from 959 ADNI participants (CN = 306, MCI = 421, AD = 232) with baseline and 24-month follow-up were analyzed. Measures included plasma serotonin, CSF biomarkers (Aβ42, total tau, p-tau181), florbetapir PET, MRI (hippocampal volume, cortical thickness), and cognitive tests (MMSE, ADAS-Cog 11, CDR-SB). Group differences were tested using ANOVA or Kruskal-Wallis, and associations were examined via partial correlations and mixed-effects models adjusted for age, sex, education, and APOE ε4, with FDR correction. The results revealed that baseline plasma serotonin levels showed a stepwise decline across the clinical continuum (CN > MCI > AD; p ≤ 0.05), consistent with progressive serotonergic dysregulation. In AD participants, higher baseline serotonin was significantly associated with less amyloid pathology and preserved brain structure, including higher CSF Aβ42 (β = 0.28, FDR p = 0.01), lower florbetapir PET SUVR (β = -0.31, FDR p = 0.02), and larger hippocampal volume (β = 0.33, FDR p = 0.02). Higher serotonin was also linked to better cognitive performance (MMSE: β = 0.22, FDR p = 0.02; ADAS-Cog 11: β = -0.24, FDR p = 0.02). Longitudinally, decreases in serotonin over 24 months in AD were associated with worsening amyloid burden (ΔPET SUVR: β = -0.29, FDR p = 0.02) and accelerated hippocampal atrophy (β = 0.32, FDR p = 0.01). Baseline serotonin predicted smaller 24-month declines in CSF Aβ42 (β = 0.28, FDR p = 0.01) and reduced hippocampal volume loss (β = 0.31, FDR p = 0.01). In CN and MCI groups, associations between serotonin and AD biomarkers or cognitive outcomes were not significant after FDR correction. On the whole, lower plasma serotonin levels are linked to amyloid pathology, hippocampal neurodegeneration, and cognitive decline in AD, supporting serotonin's potential as a stage-specific biomarker and mechanistic contributor to disease progression. Integrative longitudinal studies are needed to clarify causality and evaluate serotonergic pathways as therapeutic targets. Show less

The polyphenols in grains are highly active, but some polyphenols in highland barley are in a bound form and have extremely low bioavailability. Fermentation by lactic acid bacteria (LAB) is capable of altering the functionality of foods. This research investigated the effects of fermentation with different LAB, such as Lactobacillus acidophilus (LAC), Lactobacillus casei (LCA), Lactobacillus rhamnosus (LRH), Lactobacillus plantarum (LPL), and Lactobacillus bulgaricus (LBU), on the hypoglycemic activity and mechanism of polyphenols in highland barley. The hypoglycemic activity of the fermentation products was measured by in vitro antioxidant, enzyme activity, and glucose consumption experiments. Untargeted metabolomic analysis used UHPLC-Q Exactive HF-X/MS to reveal distinct metabolic profiles among the fermented groups. Molecular docking and western blot experiments were conducted to elucidate the mechanism underlying the hypoglycemic effect of fermentation products. Polyphenolic antioxidant activity in highland barley and its inhibitory activities against α-glucosidase and α-amylase were increased after LAC fermentation. Furthermore, the fermented extracts improved glucose consumption in HepG2 cells. The content determination and metabolomic analysis showed that fermented highland barley polyphenols were increased, and 113 differential phenolic metabolites were identified and annotated, among which 44 exhibited a significant upregulation compared with raw highland barley polyphenols. At the molecular level, the polyphenol extract upregulated PI3K and phosphorylated Akt expression in HepG2 cells. Overall, the results indicate that fermentation by LAC biotransformed highland barley polyphenols into smaller molecules with improved hypoglycemic activities, thereby enhancing their bioavailability.
