Sex Differences and Clinical Outcomes in Patients With Myocardial Infarction With Nonobstructive Coronary Arteries: A Meta-Analysis.

BACKGROUND: Although myocardial infarction with nonobstructive coronary arteries (MINOCA) is more common in women, it is unknown whether sex is a risk factor for adverse outcomes in patients with MINOCA. We aimed to investigate the relationship between sex differences and outcomes of patients with MINOCA. METHODS AND RESULTS: A systematic literature search was performed in PubMed, Embase, and Cochrane databases from their inception until August 2023 for relevant studies. End points were pooled using the Hartung-Knapp-Sidik-Jonkman random-effects model as odds ratio (OR) with 95% CIs. Nine studies, involving 30 281 patients with MINOCA (comprising 18 079 women and 12 202 men), were included in the study. Women were older and had a higher prevalence of hypertension, diabetes, and stroke compared with men. The median duration of follow-up was 3.5 years, with an interquartile range of 2.2 to 4.2 years. Pooled analysis revealed no statistically significant difference in the risk of all-cause mortality (OR, 1.03 [95% CI, 0.87-1.22]), major adverse cardiovascular events (OR, 1.18 [95% CI, 0.89-1.58]), heart failure (OR, 1.32 [95% CI, 0.57-3.03]), stroke (OR, 1.13 [95% CI, 0.56-2.26]), and myocardial infarction (OR, 1.04 [95% CI, 0.29-3.76]) between the 2 groups. Regarding short-term outcomes, women had a significantly higher risk of in-hospital major adverse cardiovascular events compared with men (OR, 1.33 [95% CI, 1.16-1.53]) whereas there was no significant difference in the risk of in-hospital mortality (OR, 0.90 [95% CI, 0.64-1.28]) between the 2 patient groups. CONCLUSIONS: Despite the differences in demographics and comorbidity profiles, there was no significant difference in the long-term outcomes for patients with MINOCA between sexes. However, it is noteworthy that women experienced a higher risk of in-hospital major adverse cardiovascular events compared with men.

Association between Proton Pump Inhibitor Use and Risk of Incident Chronic Kidney Disease: Systematic Review and Meta-Analysis.

INTRODUCTION: Proton pump inhibitors (PPIs) are among the most commonly prescribed medications. Recently, PPI use has been linked to the development of chronic kidney disease (CKD) and cardiovascular events. Our study aimed to investigate the relationship between PPI use and the incidence of chronic kidney disease using a systematic review and meta-analysis. METHODS: We performed a comprehensive literature search in PubMed, Embase, and Cochrane databases from their inception until March 2024 for relevant studies. We compared outcomes between patients using PPIs, those not using PPIs, and those using histamine-2 receptor antagonists (H2RAs). Endpoints were pooled using the DerSimonian-and-Laird random-effects model as the hazard ratio (HR) with 95% confidence intervals (CIs). RESULTS: Our analysis included twelve studies with a total of 700,125 participants (286,488 on PPIs, 373,848 not on PPIs, and 39,789 on H2RAs), with follow-up periods ranging from three months to 14 years. The current meta-analysis revealed that PPI use is associated with a statistically significant increased risk of incident CKD (HR: 1.26, 95% CI: 1.16-1.38, p < 0.001) compared with non-users. Moreover, the risk of incident CKD is significantly higher in patients with PPI use compared to H2RA use (HR: 1.34, 95% CI: 1.13-1.59, p < 0.001). The results remained unchanged in terms of magnitude and direction after a leave-one-out analysis for both outcomes. CONCLUSIONS: Our multifaceted analysis showed that PPI use was associated with a higher incidence of CKD when compared to non-PPI use and H2RA use, respectively. These findings advocate for heightened vigilance and judicious use of long-term PPIs. Further large prospective longitudinal studies are warranted to validate these observations.

Prenylated flavonoids from Sophora flavescens inhibit mushroom tyrosinase activity and modulate melanogenesis in murine melanoma cells and zebrafish.

Background: Sophora flavescens, a traditional Chinese medicine for treating conditions associated with abnormal skin pigmentation, contains flavonoids with inhibitory effects on tyrosinase. However, their mechanisms of action and their modulatory effects on melanogenesis remain unclear. Methods: Herein, a group of prenylated flavonoids was identified from S. flavescens extracts and their inhibitory activities on mushroom tyrosinase were evaluated. The anti-melanogenesis effects of these prenylated flavonoids were investigated in cellular (with murine melanoma cells) and animal (with zebrafish) models. Results: Prenylated flavonoids including isoanhydroicaritin (IAI), kurarinone (KR), and sophoraflavanone G (SG) were the major active constituents in S. flavescens extracts with anti-tyrosinase activity (IC50 = 0.7, 7.1, and 6.7 µM, respectively). Enzyme kinetic assays showed that IAI, KR, and SG had a mixed type of tyrosinase inhibition, supported by data from computational docking. Notably, KR at concentrations of 5 and 10 µM enhanced intracellular tyrosinase activity and stimulated melanin production in B16F10 cells, whereas SG and IAI did not exhibit significant activity. Further studies with the zebrafish model showed that IAI (80 and 160 µM) inhibited melanin biosynthesis by about 30.0% while KR (20 µM) stimulated melanogenesis by 36.9%. Furthermore, a zebrafish depigmentation model supported the anti-melanogenesis effect of IAI (80 and 160 µM) by 33.0% and 34.4%, respectively. Conclusion: In summary, IAI was identified as a tyrosinase inhibitor with an anti-melanogenic effect and KR was an enhancer for melanin production in B16F10 cells and zebrafish. Findings from the current study suggest that IAI and KR from S. flavescens may exert contrasting effects in the modulation of melanin production, providing important insights into the development of S. flavescens as a cosmeceutical or medicinal ingredient.

Design and synthesis of unique indole-benzosulfonamide oleanolic acid derivatives as potent antibacterial agents against MRSA.

The rapid emergence of antibiotic resistance and the scarcity of novel antibacterial agents have necessitated an urgent pursuit for the discovery and development of novel antibacterial agents against multidrug-resistant bacteria. This study involved the design and synthesis of series of novel indole-benzosulfonamide oleanolic acid (OA) derivatives, in which the indole and benzosulfonamide pharmacophores were introduced into the OA skeleton semisynthetically. These target OA derivatives show antibacterial activity against Staphylococcus strains in vitro and in vivo. Among them, derivative c17 was the most promising antibacterial agent while compared with the positive control of norfloxacin, especially against methicillin-resistant Staphylococcus aureus (MRSA) in vitro. In addition, derivative c17 also showed remarkable efficacy against MRSA-infected murine skin model, leading to a significant reduction of bacterial counts during this in vivo study. Furthermore, some preliminary studies indicated that derivative c17 could effectively inhibit and eradicate the biofilm formation, disrupt the integrity of the bacterial cell membrane. Moreover, derivative c17 showed low hemolytic activity and low toxicity to mammalian cells of NIH 3T3 and HEK 293T. These aforementioned findings strongly support the potential of novel indole-benzosulfonamide OA derivatives as anti-MRSA agents.

Four new sesquiterpenoids from the aerial parts of Pogostemon cablin (Blanco.) Benth. and their hypoglycemic activity.

Four previously undescribed sesquiterpenoids (1-4), including two natural guaiane-type sesquiterpenoids (1-2), a rearranged guaiane-type sesquiterpenoid (3), and a norsesquiterpenoid (4), were isolated from the ethanol extract of the aerial parts of Pogostemon cablin (Blanco.) Benth. Their chemical structures were determined based on extensive spectroscopic data analysis, including UV, IR, NMR, HRESIMS, and CD spectroscopy. Compound 1 exhibited a good hypoglycemic activity with glucose uptake of 124.3% and 131.2% in myotubes, respectively, at the concentrations of 20 and 40 µM and showed no cytotoxicity. These findings provide a material basis for further research on P. cablin.

Chemical Composition of Essential Oil from Citrus reticulata Blanco cv. Chachiensis (Chachi) and Its Anti-Mosquito Activity against Pyrethroid-Resistant Aedes albopictus.

The overuse of synthetic insecticides has led to various negative consequences, including insecticide resistance, environmental pollution, and harm to public health. This may be ameliorated by using insecticides derived from botanical sources. The primary objective of this study was to evaluate the anti-mosquito activity of the essential oil (EO) of Citrus reticulata Blanco cv. Chachiensis (Chachi) (referred to as CRB) at immature, semi-mature, and mature stages. The chemical compositions of the CRB EO were analyzed using GC-MS. The main components were identified to be D-limonene and γ-terpinene. The contents of D-limonene at the immature, semi-mature, and mature stages were 62.35%, 76.72%, and 73.15%, respectively; the corresponding contents of γ-terpinene were 14.26%, 11.04%, and 11.27%, respectively. In addition, the corresponding contents of a characteristic component, methyl 2-aminobenzoate, were 4.95%, 1.93%, and 2.15%, respectively. CRB EO exhibited significant larvicidal activity against Aedes albopictus (Ae. albopictus, Diptera: Culicidae), with the 50% lethal doses being 65.32, 61.47, and 65.91 mg/L for immature, semi-mature, and mature CRB EO, respectively. CRB EO was able to inhibit acetylcholinesterase and three detoxification enzymes, significantly reduce the diversity of internal microbiota in mosquitoes, and decrease the relative abundance of core species within the microbiota. The present results may provide novel insights into the utilization of plant-derived essential oils in anti-mosquitoes.

National Trends, Mortality and Outcomes in Intravascular Imaging-Guided Versus Angiography-Guided Percutaneous Coronary Intervention in the United States.

Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have become increasingly utilized in patients undergoing percutaneous coronary intervention (PCI). Despite these purported advantages, prior reports regarding the use of IVUS and OCT have indicated that contemporary use of intravascular imaging remains low with significant regional variation. Here, we present the findings of an updated contemporary analysis regarding the use of IVUS/OCT guided PCI vs. angiography-guided PCI in the United States. We also evaluated in-hospital mortality and clinical outcomes between IVUS/OCT-guided PCI versus angiography-guided PCI-only over million patients in the United States. There has been a significant decrease in the number of PCIs performed, while there has been increasing in trend of IVUS/OCT-guided PCI over this period. Most importantly, we found that IVUS/OCT guided PCI were associated with better clinical outcomes in terms of in-hospital mortality, compare with angiography guided PCI.

Autoimmune Rheumatic Diseases and Outcomes Following Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis.

Autoimmune Rheumatic Diseases (AIRDs) are associated with increased cardiovascular mortality. However, the post-percutaneous coronary intervention (PCI) outcomes in this population present a research gap, given the limited and discordant findings in existing studies. We conducted a systematic review and meta-analysis to assess the relationship between AIRDs and clinical outcomes after PCI; 9 studies with 7,027,270 patients (126,914 with AIRD, 6,900,356 without AIRD) were included. The AIRD cohort was characterized by an older age, a predominantly female demographic, and a greater prevalence of hypertension and diabetes mellitus. Over a mean follow-up period of 4.6 ± 3.5 years, AIRD patients demonstrated significantly higher odds of all-cause mortality (odds ratio (OR) 1.45, 95% CI: 1.25-1.78, P < .001) and major adverse cardiovascular events (MACE) (OR 1.63, 95% CI: 1.01-2.62, P = .04) compared with non-AIRD patients. Sensitivity analysis using adjusted estimates, confirmed the higher all-cause mortality (hazard ratio 1.32, 95% CI: 1.05-1.64, P = .01). Patients with rheumatoid arthritis had a significantly elevated odds of all-cause mortality (OR 1.50, 95% CI: 1.27-1.77) and MACE (OR 1.18, 95% CI: 1.14-1.21). Our study demonstrated an association between AIRDs and suboptimal long-term outcomes post-PCI. Prospective studies are warranted to explore the risk factors of unfavorable prognoses in patients with AIRDs.

Neuroradiological Correlation of the Lateral Third Periventricular, Pituitary Gland and Stalk, Pineal Gland, Cerebral Aqueduct, and Foramen Magendie and Luschka With Intraventricular Neuroendoscopic Images: A Case Series.

Neuroendoscopy procedures in pediatrics have expanded beyond the endoscopic third ventriculostomy. As such, a direct and angled endoscope allows further visualization around the corner, capturing the surrounding anatomy. Intraoperative live images look different than radiological images. Hence, in this single institutional experience, we correlate neuroradiology images with intraoperative intraventricular endoscopic views of the third-fourth ventricle, pituitary, pineal gland, cerebral aqueduct, and foramen magendie and luschka. Our collective case series reveals a few interesting case scenarios of normal and abnormal findings during the procedure. Careful navigation of the neuroendoscope is crucial to prevent injury to the neurovascular bundle. A close relationship with normal anatomy from radiological imaging is necessary to prevent it from getting lost once inside the ventricular cavity.

Association between Statin Use and Chemotherapy-Induced Cardiotoxicity: A Meta-Analysis.

Background: Chemotherapy-induced cardiac dysfunction (CIC) is a significant and concerning complication observed among cancer patients. Despite the demonstrated cardioprotective benefits of statins in various cardiovascular diseases, their effectiveness in mitigating CIC remains uncertain. Objective: This meta-analysis aims to comprehensively evaluate the potential cardioprotective role of statins in patients with CIC. Methods: A systematic literature search was conducted using PubMed, Embase, and Scopus databases to identify relevant articles published from inception until 10th May 2023. The outcomes were assessed using pooled odds ratio (OR) for categorical data and mean difference (MD) for continuous data, with corresponding 95% confidence intervals (95% CIs). Results: This meta-analysis comprised nine studies involving a total of 5532 patients, with 1904 in the statin group and 3628 in the non-statin group. The pooled analysis of primary outcome shows that patients who did not receive statin suffer a greater decline in the LVEF after chemotherapy compared to those who receive statin (MD, 3.55 (95% CI: 1.04-6.05), p = 0.01). Likewise, we observed a significantly higher final mean LVEF among chemotherapy patients with statin compared to the non-statin group of patients (MD, 2.08 (95% CI: 0.86-3.30), p > 0.001). Additionally, there was a lower risk of incident heart failure in the statin group compared to the non-statin group of patients (OR, 0.41 (95% CI: 0.27-0.62), p < 0.001). Lastly, the change in the mean difference for LVEDV was not statistically significant between the statin and non-statin groups (MD, 1.55 (95% CI: -5.22-8.33), p = 0.65). Conclusion: Among patients of CIC, statin use has shown cardioprotective benefits by improving left ventricular function and reducing the risk of heart failure.

Light and the Brain: A Clinical Case Depicting the Effects of Light on Brainwaves and Possible Presence of Plasma-like Brain Energy.

Light is an electromagnetic radiation that has visible and invisible wavelength spectrums. Visible light can only be detected by the eyes through the optic pathways. With the presence of the scalp, cranium, and meninges, the brain is seen as being protected from direct exposure to light. For that reason, the brain can be viewed as a black body lying inside a black box. In physics, a black body tends to be in thermal equilibrium with its environment and can tightly regulate its temperature via thermodynamic principles. Therefore, a healthy brain inside a black box should not be exposed to light. On the contrary, photobiomodulation, a form of light therapy for the brain, has been shown to have beneficial effects on some neurological conditions. The proposed underlying mechanisms are multiple. Herein, we present our intraoperative findings of rapid electrocorticographic brainwave changes when the brain was shone directly with different wavelengths of light during awake brain surgery. Our findings provide literature evidence for light's ability to influence human brain energy and function. Our proposed mechanism for these rapid changes is the presence of plasma-like energy inside the brain, which causes fast brain activities that are akin to lightning strikes.

Prognostic Value of Neutrophil-to-Lymphocyte Ratio in Patients with Acute Decompensated Heart Failure: A Meta-Analysis.

Background: Inflammation plays a pivotal role in the pathogenesis of both acute and chronic heart failure. Recent studies showed that the neutrophil-to-lymphocyte ratio (NLR) could be related to adverse outcomes in patients with cardiovascular diseases. We sought to evaluate whether NLR could predict mortality in patients with acute heart failure by means of a meta-analysis. Methods: A comprehensive literature search was performed in PubMed, Embase, and Cochrane databases through January 2023 for studies evaluating the association of NLR with mortality in patients with acute heart failure. Primary outcomes were in-hospital mortality and long-term all-cause mortality. Endpoints were pooled using a random-effects DerSimonian-and-Laird model and were expressed as a hazard ratio (HR) or mean difference (MD) with their corresponding 95% confidence intervals. Results: A total of 15 studies with 15,995 patients with acute heart failure were included in the final study. Stratifying patients based on a cut-off NLR, we found that high NLR was associated with a significantly higher in-hospital mortality [HR 1.54, 95% CI (1.18-2.00), p < 0.001] and long-term all-cause mortality [HR 1.61, 95% CI (1.40-1.86), p < 0.001] compared to the low-NLR group. Comparing the highest against the lowest NLR quartile, it was shown that patients in the highest NLR quartile has a significantly heightened risk of long-term all-cause mortality [HR 1.77, 95% CI (1.38-2.26), p < 0.001] compared to that of lowest NLR quartile. However, the risks of in-hospital mortality were compared between both quartiles of patients [HR 1.78, 95% CI (0.91-3.47), p = 0.09]. Lastly, NLR values were significantly elevated among non-survivors compared to survivors during index hospitalization [MD 5.07, 95% CI (3.34-6.80), p < 0.001] and during the follow-up period [MD 1.06, 95% CI (0.54-1.57), p < 0.001]. Conclusions: Elevated NLR was associated with an increased risk of short- and long-term mortality and could be a useful tool or incorporated in the risk stratification in patients with acute heart failure.

Association between rheumatoid arthritis and atrial fibrillation: A systematic review and meta-analysis.

Rheumatoid arthritis (RA) is an autoimmune disorder with a varying range of organs involved leading to adverse outcomes. However, very little is known, with conflicting results about the association between RA and atrial fibrillation (AF). We aim to evaluate the association between RA and AF, and other clinical outcomes. We performed a systematic literature search using PubMed, Embase, and Scopus for relevant articles from inception until September 10, 2023. Primary clinical outcomes were AF. Secondary outcomes were acute coronary syndrome (ACS), stroke, and all-cause mortality (ACM). A total of 4 679 930 patients were included in the analysis, with 81 677 patients in the RA group and 4 493 993 patients in the nonrheumatoid arthritis (NRA) group. The mean age of the patients was 57.2 years. Pooled analysis of primary outcomes shows that RA groups of patients had a significantly higher risk of AF (odds ratios [OR], 1.53; 95% confidence interval [CI]: [1.16-2.03], p < .001) compared with NRA groups. Secondary Outcomes show that the RA group of patients had significantly higher odds of ACS (OR, 1.39; 95% CI: [1.26-1.52], p < .001), and ACM (OR, 1.19; 95% CI: [1.03-1.37], p = .02) compared with the NRA groups. However, the likelihood of stroke (OR, 1.02; 95% CI: [0.94-1.11], p = .61) was comparable between both groups of patients. Our study shows that RA groups of patients are at increased risk of having AF, ACS, and ACM.

Gender Differences in the Short and Long-Term Outcomes Following Rotational Atherectomy: A Meta-Analysis.

Rotational atherectomy (RA) is used to address complex calcified coronary lesions but data regarding the association between gender and outcomes of patients who underwent RA remain uncertain. We aimed to investigate the short- and long-term outcomes of patients who underwent RA based on gender. A systematic literature search was performed in PubMed, Embase, and Cochrane databases from its inception until August 2023 for relevant studies. Endpoints were pooled using the DerSimonian and Laird random-effects model as odd ratios (OR) with 95% confidence intervals (CIs). A total of 7 studies with 8,490 patients (2,565 women and 5,925 men) who underwent RA were included in the study. In terms of periprocedural outcomes, women had a higher risk of in-hospital mortality (OR 2.00, 95% CI 1.08 to 3.68, p = 0.03), coronary dissection (OR 1.80, 95% CI 1.05 to 3.10, p = 0.03), coronary perforation (OR 1.96, 95% CI 1.19 to 3.23, p = 0.01), and stroke (OR 4.22, 95% CI 1.06 to 16.82, p = 0.04) than men. There were no significant differences between women and men in terms of major adverse cardiovascular events (OR 1.43, 95% CI 0.69 to 2.94, p = 0.33), myocardial infarction (OR 1.35, 95% CI 0.87 to 2.08, p = 0.18), bleeding (OR 1.71, 95% CI 0.88 to 3.30, p = 0.11), and cardiac tamponade (OR 2.30, 95% CI 0.45 to 11.68, p = 0.32). Over a follow-up period of 3 years, the results of meta-analysis showed that women had a higher risk of all-cause mortality (OR 1.45, 95% CI 1.19 to 1.77, p <0.001), long-term major adverse cardiovascular events (OR 1.38, 95% CI 1.10 to 1.74, p = 0.01), and long-term stroke (OR 3.41, 95% CI 1.63 to 7.17, p <0.001). The risk of long-term myocardial infarction was found to be similar between both genders (OR 1.45, 95% CI 0.95 to 2.22, p = 0.09). In conclusion, female gender is associated with adverse periprocedural and long-term outcome after RA. Women consistently demonstrated higher risk of in-hospital mortality, coronary dissection, coronary perforation, and stroke in the periprocedural period. Long-term follow-up further highlighted a heightened risk for women in terms of all-cause mortality and stroke.

Short-Term Mortality in Hospitalized Patients with Congestive Heart Failure: Markers of Thrombo-Inflammation Are Independent Risk Factors and Only Weakly Associated with Renal Insufficiency and Co-Morbidity Burden.

Congestive heart failure (CHF) is associated with significant morbidity and mortality. There has been renewed interest in using thrombo-inflammatory markers as prognostic tools in patients with CHF. To determine if thrombo-inflammatory markers are independent risk factors for 28-day mortality in hospitalized CHF patients, we retrospectively analyzed admission data extracted from 2008 consecutive patients admitted with a diagnosis of CHF to Zigong Fourth People's Hospital. Multivariate Cox proportional hazards analysis demonstrated that the thrombo-inflammatory markers thrombin time, platelet/lymphocyte ratio (PLR), and D-dimer level were independent predictors of mortality. In addition, variables reflecting the severity of CHF (New York Heart Association class > 2), impaired renal function (elevated serum creatinine [SCr]), impaired organ perfusion (elevated BUN), and chronic liver disease were also independent predictors of mortality. Thrombo-inflammatory biomarkers were only weakly associated with SCr and the burden of co-morbidity, suggesting that thrombo-inflammation may in large part be attributable to CHF itself and that, moreover, its presence may confer an increased risk of mortality. Further large-scale prospective studies are needed to determine the existence and the consequences of a thrombo-inflammatory phenotype among patients with CHF.

Clinical Outcomes of Cardiogenic Shock due to Spontaneous Coronary Artery Dissection versus Cardiogenic Shock due to Coronary Artery Disease.

Spontaneous coronary artery dissection (SCAD) can be treated conservatively. However, some SCAD patients can develop cardiogenic shock (CS). We evaluated the outcomes of SCAD-related CS using data from a national population-based cohort study from January 1, 2016, to December 30, 2019. In our study of 32,640 patients with SCAD, about 10.6% of patients presented with cardiogenic shock. We found that SCAD patients with cardiogenic shock had higher mortality as well as greater complications including use of mechanical circulatory devices, arrythmias, respiratory support, and acute heart failure compared to those without cardiogenic shock. When comparing cardiogenic shock due to SCAD with that due to coronary artery disease (CAD), we found that while mortality rates were similar, those with cardiogenic shock due to SCAD were associated with higher risk of use of mechanical circulatory support, major bleeding, blood transfusion and respiratory failure.

Vascular complications and outcomes following transcatheter aortic valve replacement in patients on chronic steroid therapy: a meta-analysis.

BACKGROUND: Chronic steroid (CS) therapy was reportedly linked to increased vascular complications following percutaneous coronary intervention. However, its association with vascular complications after transcatheter aortic valve replacement (TAVR) remained uncertain, with conflicting results being reported. OBJECTIVE: The authors aimed to compare the rate of vascular complications and outcomes between patients with and without CS use after TAVR. METHODS: The authors conducted a comprehensive literature search in PubMed, Embase, and Cochrane databases from their inception until 18th April 2022 for relevant studies. Endpoints were described according to Valve Academic Research Consortium-2 definitions. Effect sizes were pooled using DerSimonian and Laird random-effects model as risk ratio (RR) with 95% CI. RESULTS: Five studies with 6136 patients undergoing TAVR were included in the analysis. The included studies were published between 2015 and 2022. The mean ages of patients in both study groups were similar, with the CS group averaging 80 years and the nonsteroid group averaging 82 years. Notably, a higher proportion of patients in the CS group were female (56%) compared to the nonsteroid group (54%). CS use was associated with a significantly higher risk of major vascular complications (12.5 vs. 6.7%, RR 2.32, 95% CI: 1.73-3.11, P <0.001), major bleeding (16.8 vs. 13.1%, RR 1.61, 95% CI: 1.27-2.05, P <0.001), and aortic annulus rupture (2.3 vs. 0.6%, RR 4.66, 95% CI: 1.67-13.01, P <0.001). There was no significant difference in terms of minor vascular complications (RR 1.43, 95% CI: 1.00-2.04, P =0.05), in-hospital mortality (2.3 vs. 1.4%, RR 1.86, 95% CI: 0.74-4.70, P =0.19), and 30-day mortality (2.9 vs. 3.1%, RR 1.14, 95% CI: 0.53-2.46, P =0.74) between both groups. CONCLUSION: Our study showed that CS therapy is associated with increased major vascular complications, major bleeding, and annulus rupture following TAVR. Further large multicenter studies or randomized controlled trials are warranted to validate these findings.

One-Step Synthesis of Hydrogel Adhesive with Acid-Responsive Tannin Release for Diabetic Oral Mucosa Defects Healing.

The complex preparation, weak wet tissue adhesion, and limited biological activity of traditional oral wound dressings usually impede their efficient treatment and healing for diabetic oral mucosal defects. To overcome these problems, a novel hydrogel adhesive (named CFT hydrogel) is rapidly constructed using a one-step method based on dual-dynamic covalent cross-linking. Compared with the commercial oral patches, the CFT hydrogel shows superior in vivo (rat tongue) wet tissue adhesion performance. Additionally, the CFT hydrogel exhibits unique acid-responsive properties, thereby facilitating the release of bioactive molecule tannic acid in the acidic diabetic wound microenvironment. And a series of in vitro experiments substantiate the favorable biocompatibility and bioactivity properties (including antibacterial, antioxidative, anti-inflammatory, and angiogenetic effects) exhibited by CFT hydrogel. Moreover, in vivo experiments conducted on a diabetic rat model with oral mucosal defects demonstrate that the CFT hydrogel exhibits significant efficacy in protecting against mucosal wounds, alleviating inflammatory reactions, thereby facilitating the wound-healing process. Taken together, this study provides a promising and comprehensive therapeutic option with great potential for the clinical management of oral mucosa defects in diabetic patients.
