Virtual reality experiential learning improved undergraduate students' knowledge and evaluation skills relating to assistive technology for older adults and individuals with disabilities.

BACKGROUND: The aging population has caused assistive technology (AT) to receive attention. Thus, ensuring accurate user comprehension of AT has become increasingly crucial, and more specialized education for students in relevant fields is necessary. The goal of this study was to explore the learning outcomes in the context of AT for older adults and individuals with disabilities through the use of VR experiential learning. METHODS: A parallel-group design was used. Sixty third-year university students studying gerontology and long-term-care-related subjects in Taiwan were enrolled, with the experimental (VR) and control (two-dimensional [2D] video) groups each comprising 30 participants. Both groups received the same 15-minute lecture. Subsequently, the experimental group received experiential learning through a VR intervention, whereas the control group watched a 2D video to learn. The students' knowledge of AT was assessed using a pretest and posttest. Additionally, their skills in evaluation of residential environments were assessed using the Residential Environment Assessment (REA) Form for Older Adults. All data analyses were performed with SPSS version 22. RESULTS: In the posttest conducted after the intervention, the experimental group exhibited a significant 20.67 point improvement (p < 0.05), whereas the control group only exhibited improvement of 3.67 points (p = 0.317). Furthermore, the experimental group demonstrated a significantly higher score (+ 2.17 points) on the REA Form for Older Adults than did the control group (p < 0.05). CONCLUSION: VR experiential learning can significantly improve undergraduate students' knowledge and evaluation skills in relation to AT for older adults and individuals with disabilities.

Therapeutic Potential of Momordicine I from Momordica charantia: Cardiovascular Benefits and Mechanisms.

Momordica charantia (bitter melon), a traditional medicinal plant, has been demonstrated to have potential in managing diabetes, gastrointestinal problems, and infections. Among its bioactive compounds, momordicine I, a cucurbitane-type triterpenoid, has attracted attention due to its substantial biological activities. Preclinical studies have indicated that momordicine I possesses antihypertensive, anti-inflammatory, antihypertrophic, antifibrotic, and antioxidative properties, indicating its potential as a therapeutic agent for cardiovascular diseases. Its mechanisms of action include modulating insulin signaling, inhibiting inflammatory pathways, and inducing apoptosis in cancer cells. The proposed mechanistic pathways through which momordicine I exerts its cardiovascular benefits are via the modulation of nitric oxide, angiotensin-converting enzymes, phosphoinositide 3-kinase (PI3K)/ protein kinase B (Akt), oxidative stress, apoptosis and inflammatory pathways. Furthermore, the anti-inflammatory effects of momordicine I are pivotal. Momordicine I might reduce inflammation through the following mechanisms: inhibiting pro-inflammatory cytokines, reducing adhesion molecules expression, suppressing NF-κB activation, modulating the Nrf2 pathway and suppressing c-Met/STAT3 pathway. However, its therapeutic use requires the careful consideration of potential side effects, contraindications, and drug interactions. Future research should focus on elucidating the precise mechanisms of momordicine I, validating its efficacy and safety through clinical trials, and exploring its pharmacokinetics. If proven effective, momordicine I could considerably affect clinical cardiology by acting as a novel adjunct or alternative therapy for cardiovascular diseases. To date, no review article has been published on the role of bitter-melon bioactive metabolites in cardiovascular prevention and therapy. The present work constitutes a comprehensive, up-to-date review of the literature, which highlights the promising therapeutic potential of momordicine I on the cardiovascular system and discusses future research recommendations.

This review aims to comprehensively explore the association between cafestol and cardiovascular diseases. We delve into the mechanisms through which cafestol influences lipid metabolism, inflammation, and endothelial function, all of which are pivotal in cardiovascular pathophysiology. Moreover, we meticulously analyze epidemiological studies and clinical trials to elucidate the relationship between cafestol and cardiovascular outcomes. Through a critical examination of existing literature, we aim to provide insights into the potential benefits and risks associated with cafestol concerning cardiovascular health.

Referral, Diagnosis, and Pharmacological Management of Peripheral Artery Disease: Perspectives from Taiwan.

Peripheral artery disease (PAD) imposes a heavy burden of major adverse cardiovascular events that are associated with considerable mortality and morbidity, and major adverse limb events (e.g., thrombectomy, revascularization, amputation) that can substantially impact patients' daily functioning and quality of life. Global registry data have indicated that PAD is an underdiagnosed disease in Taiwan, and its associated risk factors remain inadequately controlled. This review discusses the burden of PAD in Taiwan, major guidelines on PAD management, and the latest clinical trial outcomes. Practical experience, opinions, and the latest trial data were integrated to derive a series of clinical algorithms - patient referral, PAD diagnosis, and the antithrombotic management of PAD. These algorithms can be adapted not only by physicians in Taiwan involved in the clinical management of patients with PAD but also by general practitioners in local clinics and regional hospital settings, with the ultimate aim of improving the totality of PAD patient care in Taiwan.

Discrimination of vascular aging using the arterial pulse spectrum and machine-learning analysis.

Aging contributes to the progression of vascular dysfunction and is a major nonreversible risk factor for cardiovascular disease. The aim of this study was to determine the effectiveness of using arterial pulse-wave measurements, frequency-domain pulse analysis, and machine-learning analysis in distinguishing vascular aging. Radial pulse signals were measured noninvasively for 3 min in 280 subjects aged 40-80 years. The cardio-ankle vascular index (CAVI) was used to evaluate the arterial stiffness of the subjects. Forty frequency-domain pulse indices were used as features, comprising amplitude proportion (Cn), coefficient of variation of Cn, phase angle (Pn), and standard deviation of Pn (n = 1-10). Multilayer perceptron and random forest with supervised learning were used to classify the data. The detected differences were more prominent in the subjects aged 40-50 years. Several indices differed significantly between the non-vascular-aging group (aged 40-50 years; CAVI <9) and the vascular-aging group (aged 70-80 years). Fivefold cross-validation revealed an excellent ability to discriminate the two groups (the accuracy was >80%, and the AUC was >0.8). For subjects aged 50-60 and 60-70 years, the detection accuracies of the two trained algorithms were around 80%, with AUCs of >0.73 for both, which indicated acceptable discrimination. The present method of frequency-domain analysis may improve the index reliability for further machine-learning analyses of the pulse waveform. The present noninvasive and objective methodology may be meaningful for developing a wearable-device system to reduce the threat of vascular dysfunction induced by vascular aging.

Observational study of dronedarone in Taiwanese patients with atrial fibrillation.

BACKGROUND/PURPOSE: Currently, data on the real-world use of dronedarone, an antiarrhythmic drug for atrial fibrillation (AF), are contradictory and often based on patient populations comprised of Caucasians. We prospectively investigated the efficacy and safety of dronedarone and risk factors related to treatment outcomes in a real-world use setting. METHODS: The prospective, observational, single-arm, multi-center study included a total of 824 Taiwanese patients with a diagnosis of paroxysmal or persistent AF and receiving dronedarone treatment. Risk factors analysis, efficacy, and safety of dronedarone were assessed with a follow-up of six months. RESULTS: Of the 824 patients enrolled (mean age, 75.3 ± 7.2 years), 95.2% had at least one cardiovascular risk factor. An increase in the proportion of patients with sinus rhythm following treatment was seen (52.1% at baseline vs. 67.4% at 6 months). A decrease in the mean duration of AF episodes (388.4 min vs. 62.3 min) and an increase in total AFEQT (65.4 ± 16.2 vs. 74.0 ± 11.8) were also observed after 6 months of treatment. Females, those under the age of 75, and those with symptomatic AF had higher odds of treatment success. At 6 months, 10.5% of patients reported treatment-related AEs. However, only 0.2% of the AEs were both severe in nature and causally related to dronedarone. CONCLUSION: This six-month study showed dronedarone to be relatively safe and efficacious and to improve quality-of-life in Taiwanese patients with atrial fibrillation. Odds of treatment success were related to the patient's gender, age, and AF type.

2018 Guidelines of the Taiwan Society of Cardiology, Taiwan Society of Emergency Medicine and Taiwan Society of Cardiovascular Interventions for the management of non ST-segment elevation acute coronary syndrome.

In Taiwan, the incidence of non-ST segment elevation acute coronary syndrome (NSTE-ACS) continues to increase in recent years. The purpose of this guideline is to help health care professionals in Taiwan to use adequate tests and treatments for management of NSTE-ACS. For rapid diagnosis, in addition to history and physical examination, 0/3 h rapid diagnosis protocol with high sensitivity cardiac troponin assay is recommended in this guideline. Dual antiplatelet and anticoagulation therapies are important parts in the initial treatment. Risk stratification should be performed to identify high risk patients for early coronary angiography. Through evaluation of the coronary anatomy and other clinical factors, the decision for coronary revascularization, either by percutaneous coronary intervention or coronary artery bypass grafting, should be decided by the heart team. The duration of dual antiplatelet therapy should be given for at least 12 months after discharge. Other secondary preventive medications are also recommended for long term use.

In-Hospital Implementation of Evidence-Based Medications is Associated with Improved Survival in Diabetic Patients with Acute Coronary Syndrome - Data from TSOC ACS-DM Registry.

BACKGROUND: Patients with acute coronary syndrome (ACS) and diabetes mellitus (DM) receive less aggressive treatment and have worse outcomes in Taiwan. We sought to explore whether the current practices of prescribing guideline-directed medical therapy (GDMT) for ACS and clinical outcomes have improved over time. METHODS: A total of 1534 consecutive diabetic patients with ACS were enrolled between 2013 and 2015 from 27 hospitals in the nationwide registry initiated by the Taiwan Society of Cardiology (the TSOC ACS-DM Registry). Baseline and clinical demographics, treatment, and clinical outcomes were compared to those of 1000 ACS patients with DM recruited in the Taiwan ACS-full spectrum (ACS-FS) Registry, which was performed between 2008 and 2010. RESULTS: Compared to the DM patients in the Taiwan ACS-FS Registry, even though reperfusion therapy was carried out in significantly fewer patients, the primary percutaneous coronary intervention (PCI) rate for ST-segment elevation myocardial infarction (STEMI) and the prescription rates of GDMT for ACS including P2Y12 inhibitors, renin-angiotensin blockers, beta-blockers, and statins were significantly higher in those in the TSOC ACS-DM Registry. Moreover, significant reductions in 1-year mortality, recurrent nonfatal MI and stroke were observed compared to those of the DM patients in the Taiwan ACS-FS Registry. Multivariate analysis identified reperfusion therapy in combination with GDMT as a strong predictor of better 1-year outcomes [hazard ratio (95% confidence interval) = 0.54 (0.33-0.89)]. CONCLUSIONS: Marked improvements in performing primary PCI for STEMI and prescribing GDMT for ACS were observed over time in Taiwan. This was associated with improved 1-year event-free survival in the diabetic patients with ACS.

Lipopolysaccharide pretreatment increases protease-activated receptor-2 expression and monocyte chemoattractant protein-1 secretion in vascular endothelial cells.

BACKGROUND: This study investigated whether lipopolysaccharide (LPS) increase protease-activated receptor-2 (PAR-2) expression and enhance the association between PAR-2 expression and chemokine production in human vascular endothelial cells (ECs). METHODS: The morphology of ECs was observed through microphotography in cultured human umbilical vein ECs (EA. hy926 cells) treated with various LPS concentrations (0, 0.25, 0.5, 1, and 2 µg/mL) for 24 h, and cell viability was assessed using the MTT assay. Intracellular calcium imaging was performed to assess agonist (trypsin)-induced PAR-2 activity. Western blotting was used to explore the LPS-mediated signal transduction pathway and the expression of PAR-2 and adhesion molecule monocyte chemoattractant protein-1 (MCP-1) in ECs. RESULTS: Trypsin stimulation increased intracellular calcium release in ECs. The calcium influx was augmented in cells pretreated with a high LPS concentration (1 µg/mL). After 24 h treatment of LPS, no changes in ECs viability or morphology were observed. Western blotting revealed that LPS increased PAR-2 expression and enhanced trypsin-induced extracellular signal-regulated kinase (ERK)/p38 phosphorylation and MCP-1 secretion. However, pretreatment with selective ERK (PD98059), p38 mitogen-activated protein kinase (MAPK) (SB203580) inhibitors, and the selective PAR-2 antagonist (FSLLRY-NH2) blocked the effects of LPS-activated PAR-2 on MCP-1 secretion. CONCLUSIONS: Our findings provide the first evidence that the bacterial endotoxin LPS potentiates calcium mobilization and ERK/p38 MAPK pathway activation and leads to the secretion of the pro-inflammatory chemokine MCP-1 by inducing PAR-2 expression and its associated activity in vascular ECs. Therefore, PAR-2 exerts vascular inflammatory effects and plays an important role in bacterial infection-induced pathological responses.

Longitudinal transition trajectory of gouty arthritis and its comorbidities: a population-based study.

The aim of the study was to investigate the longitudinal transition trajectory of gout and its comorbidities in male patients with gout in different age groups. A total of 3973 male patients who received a new diagnosis of gouty arthritis were identified from the Taiwan Longitudinal Health Insurance Database and divided into two age cohorts (<50 and ≥50 years). Each patient was individually followed from 2000 to 2009 to identify associated comorbidities, namely hypertension, hypercholesterolemia, diabetes mellitus, cardiovascular diseases, and chronic kidney disease. Two outcome measurements of stroke and all-cause cancer were further identified until 2010. The transition trajectory was divided into the following five phenotype groups: persistent hypertension combined with a high prevalence of various gout-related comorbidities, persistent hypercholesterolemia combined with a moderate prevalence of various gout-related comorbidities, persistent low prevalence of various gout-related comorbidities, moderate to high prevalence of various gout-related comorbidities, and low to high prevalence of various gout-related comorbidities. Although the younger and older patients had a similar longitudinal transition trajectory of gout-related comorbidities, the older patients had a higher 10-year likelihood of transition from a low or moderate to a high prevalence of various gout-related comorbidities. In addition, the incidences of stroke and all-cause cancer were higher in the groups with high and moderate to high prevalences of various gout-related comorbidities than in the other groups. The occurrence of gouty arthritis in different life stages can cause cluster effects involving varying degrees of comorbidities over time. The findings of the current study can provide additional knowledge and increase clinical awareness regarding the early assessment and management of gout-related comorbidities in clinical practice.

Statin use associated with a reduced risk of pneumonia requiring hospitalization in patients with myocardial infarction: a nested case-control study.

BACKGROUND: Statins have been reported to prevent adverse cardiovascular events in patients with myocardial infarction (MI). However, the association of statin use and the risk of pneumonia requiring hospitalization in MI patients remains unclear. METHODS: A nested case-control study was conducted by using data from the National Health Insurance Research Database of Taiwan. Among 24,975 patients with MI, 2686 case patients with pneumonia requiring hospitalization were age- and sex-matched with 10,726 control patients using the incidence density sampling approach. Duration and dosage of statin use were obtained from pharmaceutical claims. Conditional logistic regression analyses were used to estimate the risk of hospitalization for pneumonia associated with statin use adjusted for patient's demographics, medical conditions and prescribed medications. RESULTS: Statin use was associated with a 15% reduced risk of pneumonia requiring hospitalization among MI patients (adjusted odds ratio [aOR] = 0.85, 95% confidence interval [CI] = 0.77-0.95, P = 0.004). The association was more significant for MI patients unexposed to statin pretreatment (aOR = 0.76, 95% CI = 0.64-0.90, P = 0.001). Statins also exhibited favorable benefits in a time- and dose-dependent manner. The results were consistent in various subgroup analysis of the patients who were female, age ≥ 65 years, a low CHADS2 (i.e. congestive heart failure, hypertension, diabetes mellitus, previous stroke and age > 75 years old) score, and fewer comorbidities. Atorvastatin, fluvastatin and simvastatin were the most common prescribed statins and had similar effects. CONCLUSIONS: Statins might be considered as an adjunctive therapy to reduce the risk of hospitalization for pneumonia for MI patients under thorough evaluation of individual comorbidities, previous statin use and optimal dosage.

Risk of arteriovenous fistula failure associated with hypnotic use in hemodialysis patients: a nested case-control study.

PURPOSE: Hypnotic use might cause altered inflammatory processes, which have been suggested as being related to the mechanisms of arteriovenous fistula (AVF) failure. Therefore, we examined the association between the risk of AVF failure and hypnotic use in patients receiving hemodialysis (HD). METHODS: A nested case-control study was conducted using data from the National Health Insurance Research Database of Taiwan. From 34 165 HD patients, 3676 patients receiving percutaneous transluminal angioplasty or surgical thrombectomy for AVF failure were matched to 14 704 control patients according to sex, age (±1 year), and the year of initial HD therapy. The risk of AVF failure was estimated based on conditional logistic regression after adjustment for the timing of AVF creation, HD frequency, comorbidities, and prescribed medications. Hypnotic use was measured prior to the date of AVF failure of case patients and the date of pseudo-AVF failure of controls. RESULTS: Compared with matched controls, case patients were more likely to be exposed to hypnotics 30 days or an average daily defined dose > 0.5 within 90 days before the date of AVF failure, with an adjusted odds ratio of 1.21 (95% confidence interval [CI]: 1.09-1.35, p < 0.001) and 1.36 (95%CI: 1.13-1.63, p = 0.001), respectively. Risk of AVF failure associated with hypnotic use was also observed among HD patients who were male, were younger than 65 years, had hypertension, and did not use statins. CONCLUSIONS: Hypnotic use among HD patients was associated with an increased risk of AVF failure. Copyright © 2016 John Wiley & Sons, Ltd.

Nicorandil Inhibits Cyclic Strain-Induced Interleukin-8 Expression in Human Umbilical Vein Endothelial Cells.

BACKGROUND: Nicorandil, a mitochondrial adenosine triphosphate-sensitive potassium (mitoKATP) channel opener, exerts protective effects on the cardiovascular system. This study examined the effect of nicorandil on cyclic strain-induced interleukin-8 (IL-8) expression in human umbilical vein endothelial cells (HUVECs). METHODS: Cultured HUVECs were exposed to cyclic strain in the presence or absence of nicorandil (1-10 µmol/l); we then analyzed IL-8 expression. We also assessed the effects of nicorandil on heme oxygenase-1 (HO-1) expression and cyclic strain-modulated IL-8 expression after HO-1 silencing in HUVECs. SUMMARY: HUVECs exposed to cyclic strain showed increased IL-8 messenger RNA expression and protein secretion. Nicorandil (1-10 µmol/l) inhibited cyclic strain-induced IL-8 expression, whereas 5-hydroxydecanoate (100 µmol/l), a selective inhibitor of the mitoKATP channel, completely reversed the inhibitory effects of nicorandil on cyclic strain-induced IL-8 expression. We demonstrated that nicorandil increased HO-1 expression in HUVECs. In addition, cobalt protoporphyrin (10 µmol/l), an inducer of HO-1 expression, mimicked the effects of nicorandil and inhibited IL-8 expression under cyclic strain, whereas zinc protoporphyrin IX (10 µmol/l), an inhibitor of HO-1 expression, antagonized the effect of nicorandil. HO-1 silencing significantly abrogated the inhibitory effects of nicorandil on cyclic strain-induced IL-8 expression, suggesting that HO-1 plays a role in the mechanism of action of nicorandil. KEY MESSAGES: This study is the first to report that nicorandil inhibits cyclic strain-induced IL-8 expression through the induction of HO-1 expression in HUVECs. This finding provides valuable new insight into the molecular pathways contributing to the vasoprotective effects of nicorandil.

Effect of Feedback Signal on Blood Pressure Self-regulation Capability in Individuals With Prehypertension or Stage I Hypertension: A Randomized Controlled Study.

OBJECTIVES: We aimed to determine the efficacy of an 8-week direct blood pressure (BP) biofeedback training program for prehypertensive or stage I hypertensive patients with a particular focus on the impact of the authenticity of feedback signals on the efficacy of BP regulation. DESIGNS: This study has a randomized, double-blind, parallel-group design. PARTICIPANTS AND METHODS: Fifty-nine individuals with ages from 18 to 64 years and who met the criteria for the diagnosis of prehypertenion or stage 1 hypertension participated in this study. The participants were referrals from physicians or community-dwelling volunteers. No participants had taken antihypertensive medication within the previous 2 months prior to enrollment. The participants were randomly assigned to the biofeedback group (n = 31) trained with real-time BP feedback signals or the control group (n = 28) trained with pseudofeedback signals. The primary outcome measures were systolic BP (SBP) and diastolic BP (DBP). Systolic BP and DBP were assessed at baseline, 1 week after training (week 9), and 8 weeks after training (week 16) in both groups. Only 54 participants had week 16 data. RESULTS: The changes in SBP and DBP from baseline to week 9, from baseline to week 16, and from week 9 to week 16 were not significantly different between the groups (All P > 0.05). Both groups were able to significantly decrease BP after completing the training. A percentage of 45.2% of the participants in the biofeedback group and 63.0% of the participants in the control group lowered their SBP by 5 mm Hg or more at week 9. The SBP-lowering effects were also maintained for at least 8 weeks after the completion of training. CONCLUSIONS: The equivalent magnitude of BP reduction between the 2 study groups suggests that repeated practice in BP self-regulation was more likely responsible for the efficacy of direct BP biofeedback training than was the type of feedback signals.

Influenza Vaccination Reduces Hospitalization for Heart Failure in Elderly Patients with Chronic Kidney Disease: A Population-Based Cohort Study.

BACKGROUND: Elderly patients with chronic kidney disease (CKD) are at a higher risk of hospitalization for cardiovascular diseases (CVD). Previous studies have reported the beneficial effects of the influenza vaccine in patients with CVD. However, the effects of influenza vaccination on the reduction of hospitalizations for heart failure (HF) in elderly patients with CKD remain unclear. METHODS: This cohort study comprised elderly patients (≥ 55 years of age) with a recorded diagnosis of CKD (n = 4406) between January 1, 1999 and December 31, 2008. Each patient was followed-up until the end of 2008. The hazard ratio (HR) and 95% confidence interval (CI) for the association between the influenza vaccination and the first HF hospitalization were analyzed. In addition, the patients were categorized into four groups based on their vaccination status (unvaccinated and total number of vaccinations: 1, 2-3, and ≥ 4). RESULTS: We found that elderly patients with CKD receiving influenza vaccination exhibited a lower risk of HF hospitalization (adjusted HR, 0.31; 95% CI, 0.26-0.39, p < 0.001). The protective effects of influenza vaccination remained consistent regardless of the age group (55-64, 65-74, ≥ 75), sex, and influenza seasonality. When the patients were stratified according to the total number of vaccinations, the adjusted HRs for HF hospitalization were 0.60 (0.47-0.77), 0.30 (0.23-0.41), and 0.10 (0.06-0.16) for patients who received 1, 2-3, and ≥ 4 vaccinations during the follow-up period, respectively. CONCLUSIONS: The results revealed that elderly patients with CKD receiving annual influenza vaccination are at a lower risk of HF hospitalization.

Lycopene inhibits cyclic strain-induced endothelin-1 expression through the suppression of reactive oxygen species generation and induction of heme oxygenase-1 in human umbilical vein endothelial cells.

Lycopene is the most potent active antioxidant among the major carotenoids, and its use has been associated with a reduced risk for cardiovascular disease (CVD). Endothelin-1 (ET-1) is a powerful vasopressor synthesized by endothelial cells and plays a crucial role in the pathophysiology of CVD. However, the direct effects of lycopene on vascular endothelial cells have not been fully described. This study investigated the effects of lycopene on cyclic strain-induced ET-1 gene expression in human umbilical vein endothelial cells (HUVECs) and identified the signal transduction pathways that are involved in this process. Cultured HUVECs were exposed to cyclic strain (20% in length, 1 Hz) in the presence or absence of lycopene. Lycopene inhibited strain-induced ET-1 expression through the suppression of reactive oxygen species (ROS) generation through attenuation of p22(phox) mRNA expression and NAD(P)H oxidase activity. Furthermore, lycopene inhibited strain-induced ET-1 secretion by reducing ROS-mediated extrace-llular signal-regulated kinase (ERK) phosphorylation. Conversely, lycopene treatment enhanced heme oxygenase-1 (HO-1) gene expression through the activation of phosphoinositide 3-kinase (PI3K)/Akt pathway, followed by induction of the nuclear factor erythroid 2-related factor 2 (Nrf2) nuclear translocation; in addition, HO-1 silencing partially inhibited the repressive effects of lycopene on strain-induced ET-1 expression. In summary, our study showed, for the first time, that lycopene inhibits cyclic strain-induced ET-1 gene expression through the suppression of ROS generation and induction of HO-1 in HUVECs. Therefore, this study provides new valuable insight into the molecular pathways that may contribute to the proposed beneficial effects of lycopene on the cardiovascular system.

The effect of osteoarthritis on 1-year risk of ischemic heart disease following total knee arthroplasty.

To evaluate the long-term risk of ischemic heart disease (IHD) following total knee arthroplasty (TKA), we conducted a retrospective cohort study using data from the National Health Insurance Research Database of Taiwan. We evaluated 3599 primary TKA patients and 14,396 matched control patients. We further classified all patients into those with and without osteoarthritis (OA). The incidence rate of IHD was significantly higher among the TKA patients than among the matched control patients (1.13 vs 0.69 per 1000 person-months, P<.05). However, after controlling for OA, this difference was non-significant (HR=1.18, 95% confidence interval (CI): 0.63-2.20, P>.05). Our study results indicate that underlying OA conditions are predominantly responsible for increased long-term risk of IHD in TKA patients.

Unraveling autophagy-related pathogenesis in active ulcerative colitis: A bioinformatics approach.

In this editorial, we provide commentary on the study by Gong et al. In this original research article, Gong et al employed a bioinformatics approach to investigate the involvement of autophagy in active ulcerative colitis (UC). Through differential gene expression analysis, they identified 58 differentially expressed autophagy-related genes in UC patients compared to healthy controls. Notably, HSPA5, CASP1, SERPINA1, CX3CL1, and BAG3, were found to be upregulated in active UC patients, suggesting their significance as core autophagy-related targets. Enrichment analysis unveiled associations with crucial signaling pathways and diseases such as middle cerebral artery occlusion and glomerulonephritis. Moreover, immune cell infiltration analysis revealed notable differences in immune cell composition between UC patients and healthy controls. These findings offer valuable insights into the role of autophagy in UC pathogenesis and potential therapeutic targets.

Understanding Galectin-3's Role in Diastolic Dysfunction: A Contemporary Perspective.

Diastolic dysfunction, a prevalent condition characterized by impaired relaxation and filling of the left ventricle, significantly contributes to heart failure with preserved ejection fraction (HFpEF). Galectin-3, a ß-galactoside-binding lectin, has garnered attention as a potential biomarker and mediator of fibrosis and inflammation in cardiovascular diseases. This comprehensive review investigates the impact of galectin-3 on diastolic dysfunction. We explore its molecular mechanisms, including its involvement in cellular signaling pathways and interaction with components of the extracellular matrix. Evidence from both animal models and clinical studies elucidates galectin-3's role in cardiac remodeling, inflammation, and fibrosis, shedding light on the underlying pathophysiology of diastolic dysfunction. Additionally, we examine the diagnostic and therapeutic implications of galectin-3 in diastolic dysfunction, emphasizing its potential as both a biomarker and a therapeutic target. This review underscores the significance of comprehending galectin-3's role in diastolic dysfunction and its promise in enhancing diagnosis and treatment approaches for HFpEF patients.
