Cognitive reserve (CR) refers to the adaptation of cognitive performance to endure brain pathology or the aging process. CR can be categorized into static (education and occupation) or dynamic (leisure and physical activities) proxies. Typically, longitudinal studies assess CR as a composite score at baseline and cognitive performance as a global score. This study aimed to compare the relationship between different CR proxies (static and dynamic) with 9-year domain-specific cognitive trajectories, and the risk of cognitive impairment in older adults. Data from the latest four waves of the Mexican Health and Aging Study (MHAS; n = 3102, baseline mean age = 66.62 years) were used. Mixed effects models were performed with CR as independent variables and cognitive trajectories (verbal memory encoding and retrieval, verbal fluency, constructional praxis, visual attention, and memory) as outcomes. Education and leisure activities were significant positive predictors of all cognitive domains. Physical activities were a positive predictor of verbal fluency and verbal memory encoding only. Occupation was a positive predictor of verbal fluency and visual attention. Logistic regression analysis was performed to assess the relationship between CR and the risk of cognitive impairment, where education (OR: 0.79, 95% CI: 0.76, 0.83), occupational complexity (OR: 0.85, 95% CI: 0.77, 0.95), and leisure activities (OR: 0.96, 95% CI: 0.95, 0.97) were significant protective factors. Increasing the years of education can serve as a preventive strategy to delay the clinical manifestation of cognitive impairment while implementing leisure activities can act as an intervention to promote cognition even in later years.

Diabetes mellitus (DM) is identified as a potential modifier of clinical outcomes in acute heart failure (AHF), yet its prognostic impact is not fully determined. This systematic review and meta-analysis aimed to assess the prognostic impact of DM on survival outcomes in AHF patients by synthesizing evidence from 26 studies involving 326,928 subjects collected from Cochrane Library, PubMed, Web of Science, and Embase databases up to 1 June 2024. Both prospective/retrospective cohort and case-control studies published since 2000 were included, with outcomes evaluated through multivariate, univariate, and binary analyses using the Newcastle-Ottawa Scale for quality assessment. Multivariate analysis indicated that DM significantly increased the risk of all-cause mortality in AHF patients (cohort studies: HR = 1.21, 95%CI (1.13, 1.29), OR=1.15, 95%CI (1.05, 1.26); case-control studies: HR = 1.39, 95%CI (1.26, 1.53), OR=1.43, 95%CI (1.10, 1.84)]. Univariate analysis confirmed this finding in case-control studies [HR = 1.30, 95%CI (1.01, 1.67)], but not in cohort studies. In both cohort [RR = 1.27, 95%CI (1.12, 1.43)] and case-control [OR=1.21, 95%CI (1.08, 1.35)] studies, DM increased the risk of all-cause mortality. AHF patients with DM had a higher risk of cardiovascular mortality [cohort studies: HR = 1.85, 95%CI (1.46, 2.33); case-control: OR=1.70, 95%CI (1.17, 2.47)]. While multivariate analysis showed no association between DM and in-hospital mortality, case-control studies indicated an increased risk [OR=1.21, 95%CI (1.03, 1.42)]. DM also increased the risk of readmission [cohort studies: HR = 1.32, 95%CI (1.14, 1.53); case-control studies: HR = 1.44, 95%CI (1.23, 1.69); binary data: OR=1.19, 95%CI (1.07, 1.31)].This updated meta-analysis demonstrates that DM imposes significant adverse effects on all-cause mortality, cardiovascular-related mortality, and readmission risk in AHF patients. However, no significant connection was found between diabetes and survival outcomes with respect to the co-endpoint of death or readmission and the endpoint of in-hospital mortality. These findings underscore the necessity for implementing targeted diabetes management within AHF care protocols to enhance clinical outcomes, an essential consideration for future practice.

BackgroundAlzheimer’s disease and other dementias (ADRD) are significant global health concerns, with rising incidence rates and substantial social and economic implications due to population aging.
MethodsWe investigated trends in ADRD incidence from 1992 to 2021 across age, sex, and socio-demographic index (SDI) regions, utilizing data from the Global Burden of Disease (GBD) 2021 platform. An age-period-cohort (APC) model was employed to analyze the effects of age, period, and birth cohort on ADRD incidence, and a Bayesian age-period-cohort (BAPC) model was used to predict future trends.
ResultsGlobally, the age-standardized incidence rates (ASIR) remained relatively steady. However, the total number of ADRD cases witnessed a remarkable 141.25% increase, with 9,837,056 cases (95% UI: 8,620,519–11,163,700) in 2021. High SDI regions exhibited higher ASIR, whereas high-middle SDI regions showed the greatest growth, particularly among females. The net drift of ADRD incidence ranged from 0.43% per year in China to −0.68% per year in Denmark. Age effect was consistent across SDI regions, increasing exponentially with age. The 60–64 age group experienced the fastest annual incidence growth. High-middle SDI regions faced unfavorable period and cohort effects.
ConclusionAlthough progress in ADRD globally, significant regional and sex disparities persist. Strengthened surveillance and management of adults over 60 are urgently needed. Targeted public health policies and interventions are essential to address the escalating global dementia burden.

BackgroundAlthough the SBAR framework is widely used in clinical and educational settings, there is a lack of validated Spanish-language tools that objectively assess its use by students in simulation. The adaptation and validation of the SBAR-LA rubric address this gap and provide a resource for training and evaluating structured communication.
ObjectiveTo conduct the cross-cultural adaptation and psychometric validation of the SBAR-LA rubric in Spanish for assessing structured communication skills in undergraduate nursing students during clinical simulation.
MethodsA two-phase cross-sectional psychometric validation study was conducted. Phase one involved cross-cultural adaptation, including forward and backward translation, expert panel review, and cognitive debriefing with nursing students. Phase two assessed inter-rater reliability using Krippendorff’s alpha based on 97 performance evaluations obtained in different simulation scenarios. The SBAR-LA-Sp rubric contains 10 dichotomous items across the four SBAR dimensions.
ResultsThe Spanish version of the SBAR-LA rubric demonstrated excellent inter-rater reliability, with a Krippendorff’s alpha of 0.933 (95% CI: 0.905–0.956). Internal consistency and agreement between raters were also high, confirming the instrument’s robustness.
ConclusionsThe Spanish version of the SBAR-LA rubric provides an objective measure of structured communication in nursing simulation. The findings support its use in academic training. Further research is needed to examine its effect on learning outcomes.

The use of devices that facilitate rapid airway isolation is essential when managing critical patients in emergencies. In recent years, additive manufacturing has emerged as an innovative, versatile, and accessible technology for developing medical devices. This study presents the design, development, and validation of an extraglottic medical device created using computer-aided design tools and stereolithographic 3D printing to facilitate blind intubation by first responders. The device was iteratively modeled and fabricated with biocompatible materials; validation in airway simulators and human cadaveric specimens assessed dimensions, friction, intubation technique, and learning curve, and ease of use was rated with a Likert scale. Ten iterations led to a final design with low friction and minimal cervical manipulation; ramp angle, cup geometry, and distal tip were optimized for tube passage, and BioMed Flex 80A showed high strength and anatomical compatibility. The final version is a safe, reusable, and functional alternative for airway management and blind orotracheal intubation, particularly in emergencies and resource-limited settings; clinical validation in live patients is still needed.

BackgroundPenicillamine(D-Penicillamine) and trientine are first-line therapies for Wilson’s Disease (WD), yet real-world data on their adverse events (AEs) remain scarce. We analyzed the FDA Adverse Event Reporting System (FAERS) to comprehensively assess the safety of penicillamine and trientine in WD treatment.
MethodsAEs for penicillamine and trientine (2004Q1–2024Q4) were analyzed using Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR), and Bayesian Confidence Propagation Neural Network (BCPNN).
ResultsWe found 1,452 and 760 AEs related to penicillamine and trientine, respectively. In all adverse event (AE) reports, the ratio of females to males was approximately 1.3, with the highest proportion of AE reports in the 21–30 age group, and the largest number of AE reports coming from the United States. Signal detection showed that the most commonly reported AEs for penicillamine and trientine were drug hypersensitivity and tremor, respectively, with the highest proportions in the SOC categories of immune system disorders and gastrointestinal disorders. The main AEs for both drugs involved condition aggravated, and identified potential safety signals requiring further validation for the two drugs, such as decreased bone density and brain atrophy for penicillamine, and memory impairment, oesophageal ulcer and starvation for trientine. In addition, we found that women were more likely to experience drug hypersensitivity in penicillamine adverse event reports, while men were more likely to experience cutis laxa.
ConclusionThis study reveals the characteristics of AEs and potential associated risks in the clinical application of penicillamine and trientine, emphasizing individualized medication and vigilant monitoring strategies to provide guidance for safe medication use.

The Mediterranean fruit fly (Ceratitis capitata Wied.) is an agricultural pest of significant economic importance. This species has been globally managed using the Sterile Insect Technique (SIT). Insects, including tephritid flies, harbor a diverse gut microbiota that plays critical roles in their physiology, behavior, and overall fitness, suggesting that microbial communities may profoundly influence the biology of this pest. The aim of this study was to characterize the fungal and bacterial gut microbial communities of C. capitata from Tucumán, Argentina, and to assess their response to antimicrobial treatment using amplicon-based 16S rRNA gene and ITS region sequencing. Both control and treated flies were dominated by Proteobacteria (bacteria) and Zygosaccharomyces (fungi). Antimicrobial treatment induced significant shifts in bacterial and fungal composition, reducing diversity and altering gut community structure. Untreated flies exhibited a diverse and structured bacterial gut community dominated by the family Enterobacteriaceae, while antibiotic-treated communities were dominated by Rhizobiaceae. Despite these shifts, fungal communities in both treated and untreated groups were consistently dominated by the genus Zygosaccharomyces. Functional predictions revealed notable changes in metabolic pathways following antibiotic treatment, including increased gene abundance for ABC transporters and the phosphotransferase system, and decreased representation of genes involved in antibiotic biosynthesis and two-component systems. These results indicate significant alterations in bacterial metabolism and stress response mechanisms induced by the treatment. Such changes may help explain the underperformance of irradiated, mass-reared males within the context of SIT. This study provides new insights into the structural and functional dynamics of the C. capitata gut microbiome under disturbance. These findings have implications for understanding the ecological roles of microbial communities in this pest and their potential impact on fly health and fitness. Identification of dominant gut bacterial and fungal groups may support the development of probiotic diets, enhancing the efficiency of SIT application.

Inherited Epidermolysis Bullosa (EB) is a group of rare, genetic skin diseases characterized by extreme fragility of the skin and mucous membranes, leading to blistering and wounds in response to minimal trauma or friction. These clinical manifestations significantly reduce health-related quality of life (HRQoL). The objective of this protocol article is to provide information about the methods planned to be used to assess the measurement properties of HRQoL instruments specifically developed for EB patients of all age groups through a systematic review and meta-analysis. The protocol followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols (PRISMA-P) guideline. The literature search will be conducted in PubMed, Web of Science (WOS) and EMBASE, including terminology that aligns with the four key elements of the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) research question (construct, target population, measurement properties and type of PROM), as well as the terminology proposed by COSMIN for measurement properties. Studies that include information on measurement properties (specifically, validity and/or reliability) with a sample of patients with inherited EB will be selected. Both title and abstract screening and full text review, will be conducted by two independent reviewers using the Rayyan tool. In addition, the risk of bias will be assessed using the COSMIN-Risk of Bias checklist. The data from each study and each measurement property will be summarized in accordance with the COSMIN guidelines. The evidence gathered will strive to adjudicate data on measurements properties of HRQoL instruments used in EB patients, and the limitations of the future systematic review will be discussed. Ultimately, results of the future systematic review will help develop more personalized guidelines for the assessment of HRQoL in EB patients of all age groups. The protocol is registered in OSF with registration number vrm87: https://osf.io/vrm87/

Honey bees (Apis mellifera) are essential pollinators threatened by sublethal effects of pesticides such as imidacloprid, a widely used neonicotinoid that disrupts the central nervous system. However, many of the systemic effects are poorly understood, especially on the physiological homeostasis of the honey bee. We evaluated the effects of oral administration of imidacloprid and the flavonol rutin on the properties of extracellular fluid (ECF) in Apis mellifera. We measured water content, evaporation rate, electrical impedance, and ion mobility of the ECF. Our results show impacts of imidacloprid consumption, such as water content decrease, slowed evaporation, and altered electrical characteristics of the thorax segment. All these events suggest disruption of osmotic and electrochemical balance. Particularly, the rutin consumption partially mitigated the imidacloprid effects in a dose-dependent manner, enhancing detoxification. Our results point out that imidacloprid alters ionic and osmotic homeostasis beyond neural targets; and on the other hand, rutin may protect against these disruptions through physiological mechanisms beyond neuroprotection. These findings highlight new alternatives and evaluations for protecting pollinators via dietary strategies.

BackgroundLaryngeal cancer attributable to occupational asbestos exposure remains a significant public health concern, particularly in industrialized regions. This study analyzes the burden, trends, and contributing factors of laryngeal cancer due to asbestos exposure in China from 1990 to 2021.
MethodsData were obtained from the Global Burden of Disease Study (1990–2021). We analyzed age-standardized death rates, disability-adjusted life years (DALYs), years lived with disability (YLDs), and years of life lost (YLLs). Temporal trends were assessed using joinpoint and decomposition analyses, and an age-period-cohort (APC) model was applied to examine mortality and DALY trends across different cohorts.
ResultsIn 2021, there were 234 deaths and 4,430 DALYs due to laryngeal cancer attributable to occupational asbestos exposure, predominantly affecting males. Mortality rates declined from 1990 to 2008, followed by a rise until 2012, and a subsequent decline. YLDs showed a consistent increase over time. APC analysis revealed higher mortality and DALY rates in older age groups and earlier birth cohorts. Decomposition analysis indicated that epidemiological changes were the largest driver of increased deaths in men, followed by population growth and aging. For DALYs, aging and population growth were key drivers, while epidemiological changes mitigated the burden.
ConclusionsThe burden of laryngeal cancer attributable to asbestos exposure has declined overall, but disability rates continue to rise, particularly among males. Effective strategies targeting prevention, early detection, and management of asbestos exposure are needed to reduce the disease burden in China.

Dengue virus (DENV), the etiological agent of dengue fever, remains a global health concern, leading to severe illness and death in the absence of any definitive cure. Research has shown that vitamin D may reduce DENV replication in vitro and that dengue patients with low or deficient vitamin D levels are at higher risk of severe dengue. Studies indicate that viral replication is inhibited in human monocyte-derived macrophages (MDM) differentiated in the presence of vitamin D (D3MDM), suggesting that vitamin D may prevent DENV entry into host cells. However, despite these findings, the role of vitamin D in regulating the temporal expression patterns of genes as early, mid, and late transcriptional profile of DENV-infected macrophages remains unclear. Therefore, utilizing a kinetic transcriptomic profile is crucial. This approach provides detailed insights into the dynamic changes in gene expression over time, helping to clarify how vitamin D can modulate the immune response at critical stages of DENV infection. To address the transcriptional dynamics, we conducted a comprehensive analysis of gene expression patterns in MDM and D3MDM infected with Dengue virus serotype 2 (DENV-2). Utilizing bulk RNA sequencing alongside a standard viral growth curve, we systematically analyzed transcriptional kinetics by selecting key time points: 1.5, 3, 5.5, and 10 hours post-infection (h.p.i.) to monitor early viral entry and replication events and 24 h.p.i. to assess gene expression during peak viral particle production. Our temporal analysis revealed a progressive increase in cellular transcripts within the first hour of infection, with a more pronounced gene expression pattern in DENV-2-infected MDM compared to DENV-2-infected D3MDM at this early stage. Enrichment analysis indicated a reduced inflammatory response in DENV-2-infected D3MDM. Additionally, transcription factor analysis suggested diminished NF-κB signaling, but enhanced IRF5 activity was elevated in the DENV-2-infected D3MDM. High-dimensional clustering analysis identified nine unique gene clusters across both macrophage types, with notable upregulation of genes associated with antiviral activity, including IDO1, ISG20, OASL, IFI44L, RSAD2, IFIT1, MX1, EPSTI1, CXCL10, and CXCL11 in DENV-2-infected D3MDM at 1.5 h.p.i., suggesting an enhanced early antiviral response. These findings indicate that vitamin D modulates the magnitude and diversity of the early transcriptional responses, highlighting its potential as a therapeutic option to mitigate DENV severity.

BackgroundThe glucose disposal rate (eGDR) and a body shape index (ABSI) are predictors strongly associated with cardiovascular disease (CVD) and outcomes. However, whether they have additive effects on CVD risk is unknown. This study aimed to investigate whether combined assessment of eGDR and ABSI could improve prediction of CVD risk.
MethodsThe current study used data from NHANES from 1999 to 2018 and included 14,237 participants. Receiver operating characteristic (ROC) curve was used to evaluate the performance of each indicator in predicting CVD. Machine-learning algorithms were applied to screen variables to adjust the model. Finally, the ROC curve, net reclassification improvement (NRI), integrated discrimination improvement (IDI), calibration curve and decision curve analysis (DCA) were used to evaluate the predictive performance of the combination of eGDR and ABSI.
ResultsThe ROC curve showed that eGDR (C-statistics: 0.7255) and ABSI (0.7093) had the highest predictive performance. Among 14,237 participants, multivariate logistic regression showed that lower eGDR (≤6.448) and higher ABSI (≥0.086) significantly increased CVD risk (OR = 11.792, P Conclusion
The eGDR and ABSI have potential additive effects on predicting CVD risk, and have excellent predictive performance, which can evaluate cardiovascular risk more comprehensively.
