RESUMEN

Upon constant photo-excitation, the phosphorescence intensities of long-lived triplet emitters dissolved in sulfoxide solvents under air exhibit periodic oscillations with regulatable frequencies and amplitudes, which is attributed to the interplay between photochemical deoxygenation and Rayleigh-Bénard convections.

RESUMEN

The aging process is crucial for Chinese Baijiu production, significantly enhancing the spirit's flavor, aroma and quality. However, aging involves a complex interplay of numerous compounds, and the extensive duration required for aging leads to a scarcity of samples available for scientific research. These limitations pose a challenge in analyzing high-dimensional data with collinearity, complicating the understanding of the intricate chemical processes at play. In this article, a two-step framework was proposed that integrated Relaxed Lasso regression models with Lasso-selected predictors to address this issue. Baijiu samples subjected to various aging conditions were analyzed using direct GC-MS and HS-GC-MS, and the obtained data was processed by this approach. The results demonstrate significantly superior performance compared to other methods, including PLSR and Gradient Boosting. Analyses were also performed on a previously documented dataset, yielding enhanced results and underscoring the method's advantage in processing high dimensional data with multicollinearity. Moreover, this method proved effective in screening of potential indicative compounds, highlighting its utility in Baijiu aging research.

RESUMEN

BACKGROUND AND PURPOSE: Several clinical studies have demonstrated the potential of molecular-targeted agents for the treatment of recurrent or metastatic adenoid cystic carcinoma (R/M ACC). However, there is currently no consensus regarding the efficacy of molecular-targeted agents for patients with R/M ACC. This study aimed to evaluate the therapeutic efficacy and safety of molecular-targeted agents in patients with R/M ACC and provide insights to guide clinical decision-making. MATERIALS AND METHODS: Five databases (PubMed, Embase, Cochrane, ProQuest, and Scopus) were searched based on the search strategy and selection criteria. Primary endpoints were objective response rate (ORR) and progression-free survival (PFS). The secondary endpoints were disease control rate (DCR), overall survival (OS), metastatic sites, and adverse events (AE). Pooled estimates were calculated using a random-effects meta-analysis. RESULTS: Finally, 28 studies, involving 849 patients, were included. The most common metastatic sites were the lungs, bones, liver, lymph nodes, and kidneys. The pooled ORR was 4.0% (95% CI, 0.7-8.8%), the pooled DCR was 80.5% (95% CI, 72.2%-87.7%). Compared with other-target drugs, multiple kinase inhibitors (MKIs) improved the ORR (pooled ORR for single-target drugs vs. MKIs: 5.9% vs. 0%). The combination of MKIs and immune checkpoint inhibitors (ICIs) had a significantly higher ORR (17.9% in the axitinib + avelumab group). The pooled median PFS and OS were 8.35 and 25.62 months, respectively. MKIs improved the median PFS compared to other-target drugs (9.43 months vs 5.06 months). In addition, the most common adverse events (AEs) were fatigue (51.6%), hypertension (44.2%), and nausea (40.0%), followed by hand-foot skin syndrome (36.8%), diarrhoea (34.4%), weight loss (34.2%), anorexia (31.8%), rash (31.7%), and headache (29.0%). CONCLUSION: The findings of this study suggest that MKIs have a better therapeutic efficacy than single-target drugs in patients with R/M ACC. Future studies are warranted to verify the synergistic role of the combination strategy of MKIs plus ICIs, given the limited number of studies on this topic conducted and published to date.

RESUMEN

BACKGROUND: Systolic blood pressure (SBP) lowering reduces major cardiovascular disease (CVD) and all-cause mortality. However, the optimal target for SBP lowering remains controversial. METHODS: We included trials with random allocation to an SBP <130 mm Hg treatment target and CVD as the primary outcome. Data were extracted from each study independently and in duplicate using a standardized protocol. Random-effects meta-analysis was used to obtain pooled hazard ratios (HRs) and 95% CIs for CVD and all-cause mortality comparing SBP <130 and ≥130 mm Hg treatment targets. A secondary analysis compared the same outcomes for randomization to an SBP target of <120 or <140 mm Hg. RESULTS: Seven trials, including 72 138 participants, met the eligibility criteria. Compared with an SBP target of ≥130 mm Hg, an SBP target of <130 mm Hg significantly reduced major CVD (HR, 0.78 [95% CI, 0.70-0.87]) and all-cause mortality (HR, 0.89 [95% CI, 0.79-0.99]). Compared with an SBP target of <140 mm Hg, an intensive SBP target of <120 mm Hg significantly reduced major CVD (HR, 0.82 [95% CI, 0.74-0.91]), but all-cause mortality was marginally insignificant (HR, 0.85 [95% CI, 0.71-1.01]). Adverse events were significantly more likely in the intensive SBP target groups, but the absolute risks were low. CONCLUSIONS: This study suggests targeting an SBP <130 mm Hg significantly reduces the risks of major CVD and all-cause mortality. The findings also support an SBP target of <120 mm Hg, based on a smaller number of trials. REGISTRATION: URL: https://www.crd.york.ac.uk/PROSPERO/; Unique identifier: CRD42023490693.

RESUMEN

BACKGROUND: Jackfruit (Artocarpus heterophyllus Lam.) is the world's largest and heaviest fruit and adapts to hot, humid tropical climates. Low-temperature injury in winter is a primary abiotic stress, which affects jackfruit growth and development. Therefore, breeding cold-resistant varieties and identifying the vital genes in the process of cold resistance are essential. The dehydration-responsive element binding (DREB) gene family is among the subfamily of the APETALA2/ethylene response factor transcription factor family and is significant in plant abiotic stress responses. METHODS: In this study, a comparative analysis of the cold resistance property of 'GuangXi' ('GX') and 'Thailand' ('THA') jackfruit strains with different cold resistance characteristics was performed through chlorophyll fluorescence and transcriptome sequencing. RESULTS: We found that differentially expressed genes (DEGs) are significantly enriched in the metabolic processes. Here, 93 DREB genes were identified in the jackfruit genome, and phylogenetic analysis was used to classify them into seven groups. Gene structure, conserved motifs, chromosomal location, and homologous relationships were used to analyze the structural characteristics of the DREB family. Transcriptomics indicated that most of the AhDREB genes exhibited down-regulated expression in 'THA.' The DEGs AhDREB12, AhDREB21, AhDREB29, and AhDREB34 were selected for quantitative real-time PCR, and the results showed that these genes also had down-regulated expression in 'THA.' CONCLUSIONS: The above results suggest the significance of the DREB family in improving the cold resistance property of 'GX.'

RESUMEN

Rationale & Objective: Matrix metalloproteinase 2 (MMP-2) plays an important role in the development of fibrosis, the final common pathway of chronic kidney disease (CKD). This study aimed to assess the relationship between repeated measures of MMP-2 and CKD progression in a large, diverse prospective cohort. Study Design: In a prospective cohort of Chronic Renal Insufficiency Cohort (CRIC) participants (N = 3,827), MMP-2 was measured at baseline. In a case-cohort design, MMP-2 was additionally measured at year 2 in a randomly selected subcohort and cases of estimated glomerular filtration rate (eGFR) halving or kidney replacement therapy (KRT) (N = 1,439). Setting & Participants: CRIC is a multicenter prospective cohort of adults with CKD. Exposure: MMP-2 measured in plasma at baseline and at year 2. Outcomes: A composite kidney endpoint (KRT/eGFR halving). Analytical Approach: Weighted Cox proportional hazards models for case-cohort participants. Results: Participants were followed for a median of 4.6 years from year 2 and 6.9 years from the baseline. Persistently elevated MMP-2 (≥300 ng/mL at both baseline and year 2) increased the hazard of the composite kidney endpoint (HR, 1.61; 95% CI, 1.07-2.42; P = 0.09) after adjusting for covariates. The relationship of persistently elevated MMP-2 was modified by levels of inflammation, with a 2.6 times higher rate of the composite kidney endpoint in those with high-sensitivity C-reactive protein < 2.5 g/dL at study entry. Heterogeneity of effect was found with proteinuria, with a baseline MMP-2 level of ≥300 ng/mL associated with an increased risk of the composite kidney endpoint (HR, 1.30; 95% CI, 1.09-1.54) only with proteinuria ≥ 442 mg/g. Limitations: The observational study design limits causal interpretation. Conclusions: Elevated MMP-2 is associated with CKD progression, particularly among those with low inflammation and those with proteinuria. Future investigations are warranted to confirm the reduction in risk of CKD progression among these subgroups of patients with CKD.


Matrix metalloproteinase 2 (MMP-2) is a matrix-degrading protease involved in fibrosis and elevated in chronic kidney disease (CKD). Longitudinal patterns of MMP-2 have not previously been assessed as a predictor of CKD progression in a large prospective cohort. Here, we found that a higher baseline level and an increasing or persistently elevated 2-year pattern of MMP-2 were associated with CKD progression, independent of all covariates except proteinuria. The association of baseline MMP-2 with CKD progression differed by level of proteinuria, whereas levels of inflammation modified the associations of 2-year MMP-2 patterns with CKD progression.

RESUMEN

INTRODUCTION: Clonal hematopoiesis of indeterminate potential (CHIP) and dementia disproportionately burden patients with chronic kidney disease (CKD). The association between CHIP and cognitive impairment in CKD patients is unknown. METHODS: We conducted time-to-event analyses in up to 1452 older adults with CKD from the Chronic Renal Insufficiency Cohort who underwent CHIP gene sequencing. Cognition was assessed using four validated tests in up to 6 years mean follow-up time. Incident cognitive impairment was defined as a test score one standard deviation below the baseline mean. RESULTS: Compared to non-carriers, CHIP carriers were markedly less likely to experience impairment in attention (adjusted hazard ratio [HR] [95% confidence interval {CI}] = 0.44 [0.26, 0.76], p = 0.003) and executive function (adjusted HR [95% CI] = 0.60 [0.37, 0.97], p = 0.04). There were no significant associations between CHIP and impairment in global cognition or verbal memory. DISCUSSION: CHIP was associated with lower risks of impairment in attention and executive function among CKD patients. HIGHLIGHTS: Our study is the first to examine the role of CHIP in cognitive decline in CKD. CHIP markedly decreased the risk of impairment in attention and executive function. CHIP was not associated with impairment in global cognition or verbal memory.

RESUMEN

To gain a deeper understanding of the flowering pattern and reproductive characteristics of Epimedium sagittatum, to enrich the research on the flower development of E. sagittatum and its reproductive regulation, and to screen the methods suitable for the rapid detection of pollen viability of E. sagittatum and to promote its cross-breeding. The characteristics of its flower parts were observed, recorded and measured, and the pollen viability of E. sagittatumwas determined by five methods, including TTC staining, I2-KI staining, red ink staining, peroxidase method and in vitro germination method. The flowering process of E. sagittatum can be divided into five stages: calyx dehiscence, bract spathe, petal outgrowth, pollen dispersal, and pollination and withering. The results of I2-KI staining and peroxidase method were significantly higher than those of other methods; the in vitro germination method was intuitive and accurate, but the operation was complicated and time-consuming; the red ink staining method was easy to operate and had obvious staining effect, and the results were the closest to those of the in vitro germination method; and it was found that the pollen of E. sagittatum was not as effective as the in vitro germination method at the bud stamen stage, the flower stigma and the flower bud. It was also found that the pollen viability and germination rate of E. sagittatum pollen were higher in the three periods of bud spitting, petal adductor and pollen dispersal. Comparing the five methods, the red ink staining method was found to be a better method for the rapid detection of pollen viability; the best pollination periods of E. sagittatum were the bud stamen stage, petal adductor stage, and pollen dispersal stage of flowers at the peak of bloom. This study on the flowering and fruiting pattern of E. sagittatum, and the related mechanism of sexual reproduction, can be used as a reference for the next step of research on the breeding of E. sagittatum.

RESUMEN

In this study, a novel fluorescent probe, MAC-2, for the detection of Au3+ was designed and synthesised using cellulose as a carrier combined with benzothiazole derivatives. The structure of the probe was confirmed by SEM, XRD, FTIR, and 1H NMR, also the optical properties of the product were investigated. MAC-2 showed bright green fluorescence under a 365 nm UV lamp and exhibited significant quenching behaviour toward Au3+. MAC-2 utilises more sustainable biomass resources, featuring green and biodegradable characteristics that meet environmental requirements. Compared with most reported probes, it exhibits notable fluorescence properties. The limit of detection (LOD) is as low as 0.057 µM, and the response time is 1 min. It also demonstrates good specific recognition and anti-interference abilities. In addition, a smartphone was used as a portable signal processing device to achieve rapid detection of Au3+ concentration. Meanwhile, MAC-2 was successfully prepared as a fluorescent test strip, providing a potential application for the convenient detection of Au3+. The high sensitivity and selectivity exhibited by cellulose-based fluorescent probes in detecting Au3+ offer valuable insights and new ideas for the detection of other metal ions and biomolecules. These inspirations will help promote the continuous development of research and applications in related fields.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: At present,the global form of hypertension is severe,and liver-yang-hyperactivity hypertension(GYSK hypertension)is the most common type of hypertension.Folium Polygoni Cuspidati(HZY)are mainly used in Yunnan, China,to treat dizziness, headache,and hypertension caused by GYSK,and the content of the active ingredients of HZY and its efficacy varies in different periods.However,the mechanism of action and the effect of harvesting period are not clear. AIM OF THE STUDY: The purpose of this research was to investigate the effect of HZY in April and September on GYSK hypertension. MATERIALS AND METHODS: The model of GYSK hypertension was established with aconite decoction and L-NAME,and the blood pressure,the symptoms of GYSK,the cardiac index and the pathological changes of aorta were observed,to study the effect of HZY in April and September on GYSK hypertension.The chemical composition of HZY was analysed by UPLC-QTOF-MS and its mechanism for the treatment of GYSK hypertension was predicted by network pharmacological studies and experimentally validated using serum metabolomics and Western blot techniques. RESULTS: April HZY and September HZY can significantly improve the GYSK symptoms of rats, inhibit the RAAS system, improve oxidative stress and regulate blood lipids so as to play a blood pressure lowering efficacy and have a protective effect on the vascular endothelial cells.UPLC-QTOF-MS yielded 29 components of HZY,and network pharmacology predicted that its mechanism may be related to Lipid and atherosclerosis,PI3K/Akt signaling pathway, MAPK signaling pathway and TNF signaling pathway,etc.Western Blot validation showed that HZY activated PI3K,p-Akt protein expression and inhibited p-erk,p-p38 and TNF-α protein expression.Serum metabolomics suggested that April HZY exerts its efficacy mainly by regulating amino acid metabolism and September HZY mainly by regulating lipid metabolism. CONCLUSIONS: In GYSK hypertensive rats treated for three weeks, both April HZY and September HZY could have antihypertensive effects,but the mechanisms of action were different and similar, both could regulate metabolite disorders of sugars, lipids,amino acids and peptides,and regulate blood pressure through the PI3K/Akt-eNOS and MAPK signalling pathways, with the difference that April HZY had stronger regulatory effects on the metabolism of amino acids.metabolism.

RESUMEN

Importance: The China Antihypertensive Trial in Acute Ischemic Stroke II (CATIS-2) suggests that early antihypertensive treatment did not reduce the risk of dependency or death in acute ischemic stroke (AIS), compared with delayed treatment. Single subcortical infarction (SSI) is an important stroke subtype, and the association of antihypertensive timing with clinical outcomes is unclear. Objective: To investigate the association of early vs delayed antihypertensive treatment with clinical outcomes in patients with SSI, stratified by the presence of parent artery disease (PAD) stenosis. Design, Setting, and Participants: This secondary analysis of the CATIS-2 randomized clinical trial included 106 hospitals in China between June 2018 and July 2022. In CATIS-2, patients with AIS within 24 to 48 hours of symptoms onset and elevated systolic blood pressure were eligible. Patients with SSI detected in diffusion-weighted imaging were included in the current post hoc subgroup analysis. Patients were grouped into (1) SSI with PAD stenosis and (2) SSI without PAD stenosis. Statistical analysis was performed from July 2023 to May 2024. Exposures: Early (immediate) vs delayed (starting on day 8) antihypertensive therapy. Main Outcome and Measure: Primary outcome was the combination of functional dependency or death (modified Rankin Scale score ≥3) at 90 days. Results: Among 997 patients with SSI in CATIS-2 (mean [SD] age, 62.4 [9.8] years; 612 [61.4%] men), 116 (11.6%) had SSI with PAD and 881 (88.4%) had SSI without PAD. There was no significant difference in the primary outcome between early and delayed antihypertensive treatment groups among all patients with SSI (8.8% vs 7.1%; OR, 1.25 [95% CI, 0.79-1.99]; P = .34). Among patients with SSI with PAD, early antihypertensive treatment was associated with increased risk of the primary outcome compared with delayed treatment (23.4% vs 7.7%; OR, 3.67 [95% CI, 1.14-11.86]; P = .03); this finding was not observed in patients with SSI without PAD (6.6% vs 7.1%; OR, 0.93 [95% CI, 0.55-1.57]; P = .77). Significant interaction with treatment and presence of PAD stenosis was detected for the primary outcome (P for interaction = .04). Conclusions and Relevance: In this secondary analysis of a randomized clinical trial, early antihypertensive treatment was associated with an increased risk of functional dependency or death at 90 days among patients with SSI and coexisting PAD stenosis, compared with delayed antihypertensive treatment. Further studies are warranted for individualized BP management in patients with SSI by the presence of PAD. Trial Registration: ClinicalTrials.gov Identifier: NCT03479554.

RESUMEN

Background: Solitary rectal ulcer syndrome (SRUS) is a rare chronic rectal lesion with potential for malignant transformation, although cases of rapid progression to mucinous adenocarcinoma are infrequent. This case report highlights such an instance in a 29-year-old male patient, emphasizing the importance of vigilance among clinicians for detecting canceration in SRUS patients. Case Description: The patient presented with recurrent constipation and anal discomfort, initially diagnosed with SRUS based on colonoscopy and pathological examination. Despite long-term mesalazine treatment, symptoms persisted, and subsequent evaluation revealed the development of mucinous adenocarcinoma within a short period. Surgical resection, combined with adjuvant FOLFOX chemotherapy, effectively controlled cancer progression. Immunohistochemical analysis showed positive expression of MLH1(+), MSH2(+), MSH6(+), PMS2(+), and HER2(+), providing molecular insights into SRUS-associated mucinous adenocarcinoma. Conclusions: This case underscores the need for increased awareness among clinicians regarding the potential for cancerous transformation in SRUS patients. Early detection and intervention are crucial for improving outcomes in SRUS-associated malignancies. Furthermore, this case adds to existing literature by presenting a rare instance of SRUS progressing rapidly to mucinous adenocarcinoma, highlighting the significance of regular monitoring and timely intervention in such cases. Further research is warranted to elucidate underlying mechanisms and risk factors, guiding future clinical practice and treatment strategies.

RESUMEN

BACKGROUND: Globally, only 13.8% of patients with hypertension have their blood pressure (BP) controlled. Trials testing interventions to overcome barriers to BP control have produced mixed results. Type of health care professional delivering the intervention may play an important role in intervention success. The goal of this meta-analysis is to determine which health care professionals are most effective at delivering BP reduction interventions. METHODS: We searched Medline and Embase (until December 2023) for randomized controlled trials of interventions targeting barriers to hypertension control reporting who led intervention delivery. One hundred articles worldwide with 116 comparisons and 90 474 participants with hypertension were included. Trials were grouped by health care professional, and the effects of the intervention on systolic and diastolic BP were combined using random effects models and generalized estimating equations. RESULTS: Pharmacist-led interventions , community health worker-led interventions, and health educator-led interventions resulted in the greatest systolic BP reductions of -7.3 (95% CI, -9.1 to -5.6), -7.1 (95% CI, -10.8 to -3.4), and -5.2 (95% CI, -7.8 to -2.6) mm Hg, respectively. Interventions led by multiple health care professionals, nurses, and physicians also resulted in significant systolic BP reductions of -4.2 (95% CI, -6.1 to -2.4), -3.0 (95% CI, -4.2 to -1.9), and -2.4 (95% CI, -3.4 to -1.5) mm Hg, respectively. Similarly, the greatest diastolic BP reductions were -3.9 (95% CI, -5.2 to -2.5) mm Hg for pharmacist-led and -3.7 (95% CI, -6.6 to -0.8) mm Hg for community health worker-led interventions. In pairwise comparisons, pharmacist were significantly more effective than multiple health care professionals, nurses, and physicians at delivering interventions. CONCLUSIONS: Pharmacists and community health workers are most effective at leading BP intervention implementation and should be prioritized in future hypertension control efforts.

RESUMEN

Nationwide estimates of the impact of common modifiable risk factors on mortality remain crucial. We aim to assess the influence of social determinants, lifestyle, and metabolic factors on mortality in 174,004 adults aged ≥40 years from the China Cardiometabolic Disease and Cancer Cohort (4C) Study. We reveal that 17 modifiable factors are independently associated with mortality, accounting for 64.8% of all-cause mortality, 77.4% of cardiovascular mortality, and 44.8% of cancer mortality. Low education emerges as the leading factor for both all-cause and cancer mortality, while hypertension is predominant for cardiovascular mortality. Moreover, low gross domestic product per capita and high ambient particulate matter with a diameter of <2.5 µm (PM2.5) air pollution account for 7.8% and 4.3% for all-cause mortality, respectively, using a different method. Gender-specific analyses reveal distinct patterns, with women's mortality primarily associated with social determinants and men exhibiting stronger associations with lifestyle factors. Targeted health interventions are essential to mitigate mortality risks effectively in China.

RESUMEN

Background: Clonal hematopoiesis of indeterminate potential (CHIP) is a common inflammatory condition of aging that causes myriad end-organ damage. We have recently shown associations for CHIP with acute kidney injury and with kidney function decline in the general population, with stronger associations for CHIP driven by mutations in genes other than DNMT3A (non- DNMT3A CHIP). Longitudinal kidney function endpoints in individuals with pre-existing chronic kidney disease (CKD) and CHIP have been examined in two previous studies, which reported conflicting findings and were limited by small sample sizes. Methods: In this study, we examined the prospective associations between CHIP and CKD progression events in four cohorts of CKD patients (total N = 5,772). The primary outcome was a composite of 50% kidney function decline or kidney failure. The slope of eGFR decline was examined as a secondary outcome. Mendelian randomization techniques were then used to investigate potential causal effects of CHIP on eGFR decline. Finally, kidney function was assessed in adenine-fed CKD model mice having received a bone marrow transplant recapitulating Tet2 -CHIP compared to controls transplanted wild-type bone marrow. Results: Across all cohorts, the average age was 66.4 years, the average baseline eGFR was 42.6 ml/min/1.73m 2 , and 24% had CHIP. Upon meta-analysis, non- DNMT3A CHIP was associated with a 59% higher relative risk of incident CKD progression (HR 1.59, 95% CI: 1.02-2.47). This association was more pronounced among individuals with diabetes (HR 1.29, 95% CI: 1.03-1.62) and with baseline eGFR ≥ 30 ml/min/1.73m (HR 1.80, 95% CI: 1.11-2.90). Additionally, the annualized slope of eGFR decline was steeper among non- DNMT3A CHIP carriers, relative to non-carriers (ß -0.61 ± 0.31 ml/min/1.73m 2 , p = 0.04). Mendelian randomization analyses suggested a causal role for CHIP in eGFR decline among individuals with diabetes. In a dietary adenine mouse model of CKD, Tet2 -CHIP was associated with lower GFR as well as greater kidney inflammation, tubular injury, and tubulointerstitial fibrosis. Conclusion: Non- DNMT3A CHIP is a potentially targetable novel risk factor for CKD progression.

RESUMEN

Background: ß-blockers have been widely used in patients with extensive cardiovascular disease (CVD) and have provided benefits. However, they are more likely to cause symptomatic bradycardia, hypotension, or glucose metabolism disorders, which may lead to an increased risk of atrial fibrillation (AF), but evidence is lacking. Aims: This study was to analyze the association between the use of ß-blockers and the risk of developing AF. Methods: This nationwide, prospective cohort study utilized data from the 2013-2020 National Health and Nutrition Examination Survey (NHANES). The patients were stratified into a ß-blocker treatment group (n = 2585) and a non-ß-blocker treatment group (n = 8525). Univariate and multivariate logistic regression analyses were performed to identify the relationship between ß-blockades and the risk of AF. Propensity matching analysis was used to balance patient baseline characteristics and to control for confounders. Results: A total of 11,110 subjects were included in this study (mean [SD] age, 59.89 [15.07] years; 5657 [49.7%] males). A total of 111/2585 subjects developed AF in the ß-blocker treatment group, and 75/8525 developed AF in the non-ß-blocker treatment group (incidence rate, 4.2% vs. 0.8%). Compared with the non-ß-blocker group, the ß-blocker group had an increased risk of incident AF (aOR, 2.339; 95% CI, 1.614-3.410). Some sensitivity analyses also revealed consistent findings of increased AF risk associated with ß-blocker treatment. Conclusion: The findings from this study suggest that ß-blocker treatment is associated with an increased risk of incident AF and may help physicians select a modest medication for patients while also assessing the risk of AF.

RESUMEN

Although epigenetic age acceleration (EAA) might serve as a molecular signature of childhood cardiovascular disease (CVD) risk factors and further promote midlife subclinical CVD, few studies have comprehensively examined these life course associations. This study sought to test whether childhood CVD risk factors predict EAA in adulthood and whether EAA mediates the association between childhood CVD risks and midlife subclinical disease. Among 1,580 Bogalusa Heart Study participants, we estimated extrinsic EAA, intrinsic EAA, PhenoAge acceleration (PhenoAgeAccel), and GrimAge acceleration (GrimAgeAccel) during adulthood. We tested prospective associations of longitudinal childhood body mass index (BMI), blood pressure, lipids, and glucose with EAAs using linear mixed effects models. After confirming EAAs with midlife carotid intima-media thickness and carotid plaque, structural equation models examined mediating effects of EAAs on associations of childhood CVD risk factors with subclinical CVD measures. After stringent multiple testing corrections, each SD increase in childhood BMI was significantly associated with 0.6-, 0.9-, and 0.5-year increases in extrinsic EAA, PhenoAgeAccel, and GrimAgeAccel, respectively (P < 0.001 for all 3 associations). Likewise, each SD increase in childhood log-triglycerides was associated with 0.5- and 0.4-year increases in PhenoAgeAccel and GrimAgeAccel (P < 0.001 for both), respectively, whereas each SD increase in childhood high-density lipoprotein cholesterol was associated with a 0.3-year decrease in GrimAgeAccel (P = 0.002). Our findings indicate that PhenoAgeAccel mediates an estimated 27.4% of the association between childhood log-triglycerides and midlife carotid intima-media thickness (P = 0.022). Our data demonstrate that early life CVD risk factors may accelerate biological aging and promote subclinical atherosclerosis.

RESUMEN

Coelenterates, such as Atolla jellyfish, are capable of integrating color, communication, and motion in a sophisticated manner, thereby enabling them to function as intelligent biological systems that can adapt to the challenges of the underwater environment. Extensive efforts have been dedicated to exploiting underwater visual, sensory, actuating, or combined systems. However, current biomimetic soft systems are still limited by the lack of comprehensive, integrated functional skins that can automatically deform, dynamically sense, and further send color signals when diving into underwater conditions. Here, we propose the synthetic soft skins composed of assembled entangled carbon nanotube networks and fluorescent unit-embedded elastomers which can be applied in a suspended form to allow autonomic 3D deformation, real-time perception, and dynamic fluorescence color transformation. The capabilities of the sensory and color display thresholds were controlled through the entanglement density of carbon nanotubes and the suspended area. As a demonstration, the soft thin skin was integrated into an artificial jellyfish robot, enabling the realization of a closed-loop feedback system for dynamic sensory processing, signal processing, and further 3D morphing-induced fluorescent color change, demonstrating significant potentials in underwater visual display, danger warning, and environmental exploration.

RESUMEN

BACKGROUND: Polyamines have been reported to be associated with neurological function, but the associations between polyamines and the prognosis of ischemic stroke remain unclear. We aimed to prospectively investigate whether elevated plasma polyamine levels are associated with adverse outcomes in patients with ischemic stroke. METHODS AND RESULTS: Plasma polyamine levels were measured at admission in 3570 patients with acute ischemic stroke, and clinical outcomes were assessed at 3 months after stroke onset. The primary outcome was a composite outcome of death and major disability (modified Rankin Scale score≥3), and secondary outcomes included the individual outcomes of death and major disability. During a 3-month follow-up period, 877 participants (25.1%) experienced the primary outcome. Increased putrescines were associated with a decreased risk of the primary outcome (the highest versus the lowest tertile: odds ratio, 0.72 [95% CI, 0.58-0.91]; P=0.005) and major disability (odds ratio, 0.59 [95% CI, 0.47-0.74]; P<0.001). Conversely, increased spermidines were associated with an increased risk of death (hazard ratio, 1.86 [95% CI, 1.10-3.14]; P=0.020), and increased spermines were associated with an increased risk of the primary outcome (odds ratio, 1.36 [95% CI, 1.08-1.71]; P=0.009) and major disability (odds ratio, 1.27 [95% CI, 1.01-1.59]; P=0.041). CONCLUSIONS: Among patients with ischemic stroke, high plasma putrescine levels were associated with a decreased risk of adverse outcomes, whereas high plasma spermidine and spermine levels were associated with an increased risk of adverse outcomes. Further studies are needed to investigate whether targeting these polyamines can improve the prognosis of patients with ischemic stroke. REGISTRATION: https://clinicaltrials.gov.
