BACKGROUND Prediabetes is a well-established risk factor for major adverse cardiac and cerebrovascular events(MACCE).However,the relationship between prediabetes and MACCE in atrial fibrillation(AF)patients has not been extensively studied.Therefore,this study aimed to establish a link between prediabetes and MACCE in AF patients.AIM To investigate a link between prediabetes and MACCE in AF patients.METHODS We used the National Inpatient Sample(2019)and relevant ICD-10 CM codes to identify hospitalizations with AF and categorized them into groups with and without prediabetes,excluding diabetics.The primary outcome was MACCE(all-cause inpatient mortality,cardiac arrest including ventricular fibrillation,and stroke)in AF-related hospitalizations.RESULTS Of the 2965875 AF-related hospitalizations for MACCE,47505(1.6%)were among patients with prediabetes.The prediabetes cohort was relatively younger(median 75 vs 78 years),and often consisted of males(56.3%vs 51.4%),blacks(9.8%vs 7.9%),Hispanics(7.3%vs 4.3%),and Asians(4.7%vs 1.6%)than the non-prediabetic cohort(P<0.001).The prediabetes group had significantly higher rates of hypertension,hyperlipidemia,smoking,obesity,drug abuse,prior myocardial infarction,peripheral vascular disease,and hyperthyroidism(all P<0.05).The prediabetes cohort was often discharged routinely(51.1%vs 41.1%),but more frequently required home health care(23.6%vs 21.0%)and had higher costs.After adjusting for baseline characteristics or comorbidities,the prediabetes cohort with AF admissions showed a higher rate and significantly higher odds of MACCE compared to the non-prediabetic cohort[18.6%vs 14.7%,odds ratio(OR)1.34,95%confidence interval 1.26-1.42,P<0.001].On subgroup analyses,males had a stronger association(aOR 1.43)compared to females(aOR 1.22),whereas on the race-wise comparison,Hispanics(aOR 1.43)and Asians(aOR 1.36)had a stronger association with MACCE with prediabetes vs whites(aOR 1.33)and blacks(aOR 1.21).CONCLUSION This population-based study found a significant association between prediabetes and MACCE in AF patients.Therefore,there is a need for further research to actively screen and manage prediabetes in AF to prevent MACCE. 展开更多

Alzheimer’s disease(AD)stands out as the primary manifestation of age-related dementia,portraying a chronic neurodegenerative disorder distinguished by the accumulation of fibrillar amyloid-β(Aβ)plaques and neurofibrillary tangles of hyperphosphorylated tau.However,from a clinical standpoint,AD presents itself as a complex condition with a spectrum of dysfunctions rather than a singular pathological mechanism.An often-overlooked aspect of the disease is the presence of extensive cerebrovascular abnormalities,given that the majority of AD patients experience altered cerebral blood flow,damaged vasculature,increased microinfarcts and microhemorrhages.Animal models of AD further support this observation,showing cerebrovascular dysfunction such as impaired cerebral blood flow and altered cerebrovascular reactivity(Tataryn et al.,2021;Gareau et al.,2023). 展开更多

Microvasculature of the retina is considered an alternative marker of cerebral vascular risk in healthy populations.However,the ability of retinal vasculature changes,specifically focusing on retinal vessel diameter,to predict the recurrence of cerebrovascular events in patients with ischemic stroke has not been determined comprehensively.While previous studies have shown a link between retinal vessel diameter and recurrent cerebrovascular events,they have not incorporated this information into a predictive model.Therefore,this study aimed to investigate the relationship between retinal vessel diameter and subsequent cerebrovascular events in patients with acute ischemic stroke.Additionally,we sought to establish a predictive model by combining retinal veessel diameter with traditional risk factors.We performed a prospective observational study of 141 patients with acute ischemic stroke who were admitted to the First Affiliated Hospital of Jinan University.All of these patients underwent digital retinal imaging within 72 hours of admission and were followed up for 3 years.We found that,after adjusting for related risk factors,patients with acute ischemic stroke with mean arteriolar diameter within 0.5-1.0 disc diameters of the disc margin(MAD_(0.5-1.0DD))of≥74.14μm and mean venular diameter within 0.5-1.0 disc diameters of the disc margin(MVD_(0.5-1.0DD))of≥83.91μm tended to experience recurrent cerebrovascular events.We established three multivariate Cox proportional hazard regression models:model 1 included traditional risk factors,model 2 added MAD_(0.5-1.0DD)to model 1,and model 3 added MVD0.5-1.0DD to model 1.Model 3 had the greatest potential to predict subsequent cerebrovascular events,followed by model 2,and finally model 1.These findings indicate that combining retinal venular or arteriolar diameter with traditional risk factors could improve the prediction of recurrent cerebrovascular events in patients with acute ischemic stroke,and that retinal imaging could be a useful and non-invasive method for identifying high-risk patients who require closer monitoring and more aggressive management. 展开更多

In patients with Alzheimer’s disease,gamma-glutamyl transferase 5(GGT5)expression has been observed to be downregulated in cerebrovascular endothelial cells.However,the functional role of GGT5 in the development of Alzheimer’s disease remains unclear.This study aimed to explore the effect of GGT5 on cognitive function and brain pathology in an APP/PS1 mouse model of Alzheimer’s disease,as well as the underlying mechanism.We observed a significant reduction in GGT5 expression in two in vitro models of Alzheimer’s disease(Aβ_(1-42)-treated hCMEC/D3 and bEnd.3 cells),as well as in the APP/PS1 mouse model.Additionally,injection of APP/PS1 mice with an adeno-associated virus encoding GGT5 enhanced hippocampal synaptic plasticity and mitigated cognitive deficits.Interestingly,increasing GGT5 expression in cerebrovascular endothelial cells reduced levels of both soluble and insoluble amyloid-βin the brains of APP/PS1 mice.This effect may be attributable to inhibition of the expression ofβ-site APP cleaving enzyme 1,which is mediated by nuclear factor-kappa B.Our findings demonstrate that GGT5 expression in cerebrovascular endothelial cells is inversely associated with Alzheimer’s disease pathogenesis,and that GGT5 upregulation mitigates cognitive deficits in APP/PS1 mice.These findings suggest that GGT5 expression in cerebrovascular endothelial cells is a potential therapeutic target and biomarker for Alzheimer’s disease. 展开更多

Objective: To explore the impact of interventional nursing on the therapeutic effect, negative emotions, and quality of life of patients undergoing cardiovascular and cerebrovascular interventional therapy. Methods: A total of 106 patients who underwent cardiovascular and cerebrovascular interventional treatment were collected and randomly divided into Group A (control) and Group B (observation), with 53 cases each. Group A received the routine nursing intervention and Group B received the interventional nursing intervention. The clinical efficacy, complications, negative emotions, quality of life, and nursing satisfaction of the two groups of patients were evaluated. Results: The total clinical effective rate of Group B (52/98.12%) was higher than that of Group A (45/84.91%) (χ^(2)= 4.371, P < 0.05). The total incidence of complications in Group B (2/3.78%) was lower than that of Group A (9/16.98%) (χ^(2)= 4.970, P < 0.05). The self-rating anxiety (SAS) score and self-rating depression (SDS) of Group B were lower than those of Group A (P < 0.001). The quality of life of Group B was significantly higher than that of Group A (P < 0.001). The nursing satisfaction of group B (51/96.22%) was higher than that of group A (43/81.13%) (χ^(2)= 6.014, P < 0.05). Conclusion: In the care of patients undergoing cardiovascular and cerebrovascular interventional therapy, interventional nursing intervention effectively improved the patient’s clinical efficacy, reduced the incidence of complications, reduced negative emotions, improved the quality of life, and increased nursing satisfaction. 展开更多

Catalpol,an iridoid glucoside isolated from Rehmannia glutinosa,has gained attention due to its potential use in treating cardio-cerebrovascular diseases(CVDs).This extensive review delves into recent studies on catalpol's protective properties in relation to various CVDs,such as atherosclerosis,myocardial ischemia,infarction,cardiac hypertrophy,and heart failure.The review also explores the compound's anti-oxidant,anti-inflammatory,and anti-apoptotic characteristics,emphasizing the role of vital signaling pathways,including PGC-1a/TERT,PI3K/Akt,AMPK,Nrf2/HO-1,estrogen receptor(ER),Nox4/NF-kB,and GRP78/PERK.The article discusses emerging findings on catalpol's ability to alleviate diabetic cardiovascular complications,thrombosis,and other cardiovascular-related conditions.Although clinical studies specifically addressing catalpol's impact on CVDs are scarce,the compound's established safety and well-tolerated nature suggest that it could be a valuable treatment alternative for CVD patients.Further investigation into catalpol and related iridoid derivatives may unveil new opportunities for devising natural and efficacious CVD therapies. 展开更多

Background:Spontaneous heparin-induced thrombocytopenia is a pro-thrombotic syndrome in which anti-heparin antibodies develop without heparin exposure.Case presentation:A 78-year-old man who underwent a successful lumbar laminectomy presented to the hospital 5 days after discharge for stroke-like symptoms and was found to have acute infarcts of the bilateral frontal lobes.The patient was found to be severely thrombocytopenic and was incidentally found to have an inferior wall myocardial infarction.Further investigation led to the diagnosis of bilateral lower extremity deep vein thromboses.His overall clinical presentation prompted a detailed hematologic workup that indicated positivity for heparin-induced thrombocy-topenia despite no previous exposure to heparin products.Conclusions:This case illustrates a patient with no prior lifetime heparin exposure who underwent laminectomy with subsequent development of acute infarcts of the bilateral frontal lobes,an inferior wall myocardial infarction,and bilateral lower extremity deep vein thromboses,with concern for sequelae of spontaneous heparin-induced thrombo-cytopenia. 展开更多

Introduction: The frequency, severity, cost of treatment, morbidity and mortality of stroke make it a real public health problem. In industrialized countries, strokes are the leading cause of physical disability in adults, the second leading cause of dementia (after Alzheimer’s disease), and the third leading cause of death (after cancer and cardiovascular disease). It’s also a major cause of depression. The objective of our study was to describe the epidemiological, clinical and evolutionary aspects of stroke in the internal medicine department of Tivaouane Hospital. Material and Method: This is a retrospective study carried out from January 1, 2015 to December 31, 2018 on the files of patients hospitalized for stroke in the medical department of the EPS1 in Tivaouane. We took into account all the patients who had a brain CT (computed tomography) scan. We collected data related to socio-demographic characteristics, history, risk factors, reasons for admission, clinical signs, paraclinical examinations, as well as evolution. Results: Out of 1999 patients, 206 files of patients with stroke were collected, i.e. a proportion of 10.3%. Our study population had a mean age of 65.53 years [16 - 97 years]. We noted a clear predominance of women (50.5%). The majority of the population came from the outskirts of Tivaouane (56.7%). Risk factors for stroke were dominated by hypertension (90.3%), dyslipidemia (19.4%), previous stroke (18.9%), and diabetes (16%). The clinical signs were dominated by a motor deficit (94.1%), speech disorders (67.4%) and consciousness disorders (47%). Ischemic strokes were predominant (65%) over hemorrhagic strokes (34.5%). The outcome was generally unfavorable with 14.6% total recovery, 58.7% recovery with sequelae and a case fatality of 26.7%. Conclusion: It emerges from this study that strokes still remain a real public health problem. Knowledge of populations of risk factors as well as their proper management is fundamental in primary prevention strategies, the only guarantee for a reduction in the still very high morbidity and mortality of this disease. 展开更多
