Ultrasound-guided microwave ablation versus surgery for solitary T1bN0M0 papillary thyroid carcinoma: a prospective multicenter study.

OBJECTIVE: Microwave ablation (MWA) has emerged as a minimally invasive technology for papillary thyroid microcarcinoma (PTMC), but it has not been widely applied to treat T1bN0M0 PTC with high-level evidence. This study was designed to compare the real-world efficacy and safety of MWA or surgery for treating T1bN0M0 PTC. METHODS: From December 2019 to April 2021, 123 continuous unifocal T1bN0M0 PTC patients without lymph node metastasis (LNM) or distant metastasis (DM) were included from 10 hospitals. Patients were allocated into the MWA or surgery group based on their willingness. The main outcomes were local tumour progression (LTP), new thyroid cancer, LNM, and DM. The secondary outcomes included changes in tumour size and volume, complications, and cosmetic results. Subgroup analyses were conducted to identify influencing factors. RESULTS: Fifty-two patients chose MWA, and 71 patients chose surgery. Patients had similar demographic information and tumour characteristics in the two groups. The follow-up durations after MWA and surgery were 10.6 ± 4.2 and 10.4 ± 3.4 months, respectively. The LNM rate was 5.8% in the MWA group and 1.4% in the surgery group (p = 0.177). No LTP, new thyroid cancer, or distant metastasis (DM) occurred in either group. Five (9.6%) of the 52 patients in the MWA group and 8 (11.3%) of the 71 patients in the surgery group had complications (p = 0.27). Better cosmetic results were found in the MWA group (p < 0.01). CONCLUSION: MWA achieved comparable short-term treatment efficacy with surgery. MWA might be an optional choice for surgery for low-risk T1bN0M0 PTC but concerns about LNM need to be studied further. CLINICAL RELEVANCE STATEMENT: MWA achieved comparable short-time treatment efficacy with surgery. MWA might be an optional choice for surgery for low-risk T1bN0M0 PTC. KEY POINTS: • MWA achieved comparable short-term treatment efficacy with surgery. MWA might be an optional choice for surgery for low-risk T1bN0M0 PTC but concerns about LNM need to be studied further. • The complication rate in the surgery group was higher than that in the MWA group without a significant difference. • There was no statistically significant difference in the LNM rate between the MWA and surgery groups.

miR-541 is associated with the prognosis of liver cirrhosis and directly targets JAG2 to inhibit the activation of hepatic stellate cells.

BACKGROUND: The activation of hepatic stellate cells (HSCs) has been emphasized as a leading event of the pathogenesis of liver cirrhosis, while the exact mechanism of its activation is largely unknown. Furthermore, the novel non-invasive predictors of prognosis in cirrhotic patients warrant more exploration. miR-541 has been identified as a tumor suppressor in hepatocellular carcinoma and a regulator of fibrotic disease, such as lung fibrosis and renal fibrosis. However, its role in liver cirrhosis has not been reported. METHODS: Real-time PCR was used to detect miR-541 expression in the liver tissues and sera of liver cirrhosis patients and in the human LX-2. Gain- and loss-of-function assays were performed to evaluate the effects of miR-541 on the activation of LX-2. Bioinformatics analysis and a luciferase reporter assay were conducted to investigate the target gene of miR-541. RESULTS: miR-541 was downregulated in the tissues and sera of patients with liver cirrhosis, which was exacerbated by deteriorating disease severity. Importantly, the lower expression of miR-541 was associated with more episodes of complications including ascites and hepatic encephalopathy, a shorter overall lifespan, and decompensation-free survival. Moreover, multivariate Cox's regression analysis verified lower serum miR-541 as an independent risk factor for liver-related death in cirrhotic patients (HR = 0.394; 95% CI: 0.164-0.947; P = 0.037). miR-541 was also decreased in LX-2 cells activated by TGF-ß and the overexpression of miR-541 inhibited the proliferation, activation and hydroxyproline secretion of LX-2 cells. JAG2 is an important ligand of Notch signaling and was identified as a direct target gene of miR-541. The expression of JAG2 was upregulated in the liver tissues of cirrhotic patients and was inversely correlated with miR-541 levels. A rescue assay further confirmed that JAG2 was involved in the function of miR-541 when regulating LX-2 activation and Notch signaling. CONCLUSIONS: Dysregulation of miR-541/JAG2 axis might be a as a new mechanism of liver fibrosis, and miR-541 could serve as a novel non-invasive biomarker and therapeutic targets for liver cirrhosis.

Identification of novel risk factors for postoperative severe hypocalcemia in patients with primary hyperparathyroidism undergoing parathyroidectomy: a case control study.

BACKGROUND: Patients with primary hyperparathyroidism (PHPT) are at risk for severe hypocalcemia (SH) following parathyroidectomy (PTX), but limited data exist on the predictors of SH. We aimed to identify risk factors for early postoperative SH after PTX in patients with PHPT and to evaluate the predictive value of clinical parameters. METHODS: A retrospective review of patients with PHPT who underwent PTX between January 2010 and December 2022 was performed. A total of 46 patients were included in the study, with 15 (32.6%) experiencing postoperative SH, 19 (41.3%) having calculi in the ureter or kidney, and 37 (80.4%) having osteoporosis. Patients were divided into SH and non-SH groups based on postoperative serum calcium levels. Preoperative biochemical indicators, bone turnover markers, and renal function parameters were analyzed and correlated with postoperative SH. RESULTS: Statistically significant (P < 0.05) differences were found in preoperative serum calcium (serum Ca), intact parathyroid hormone, serum phosphorus (serum P), serum Ca/P, percentage decrease of serum Ca, total procollagen type 1 intact N-terminal propeptide, osteocalcin (OC), and alkaline phosphatase levels between the two groups. Multivariate analysis showed that serum P (odds ratio [OR] = 0.989; 95% confidence interval [95% CI] = 0.981-0.996; P = 0.003), serum Ca (OR = 0.007; 95% CI = 0.001-0.415; P = 0.017), serum Ca/P (OR = 0.135; 95% CI = 0.019-0.947; P = 0.044) and OC levels (OR = 1.012; 95% CI = 1.001-1.024; P = 0.036) were predictors of early postoperative SH. The receiver operating characteristic curve analysis revealed that serum P (area under the curve [AUC] = 0.859, P < 0.001), serum Ca/P (AUC = 0.735, P = 0.010) and OC (AUC = 0.729, P = 0.013) had high sensitivity and specificity. CONCLUSION: Preoperative serum P, serum Ca/P and osteocalcin levels may identify patients with PHPT at risk for early postoperative SH after PTX.

Conducting family meetings on families with dementia: An integrative review.

AIM: To explore the role of family meetings for individuals living with dementia and their family caregivers. DESIGN: Integrative review. METHODS: We conducted searches in the Cochrane Library, PubMed, CINAHL, and Embase databases (up to December 2022). Additionally, an ancestry search strategy was employed to supplement the retrieval of published literature related to family meetings or family conferences for people with dementia and their family caregivers. RESULTS: The review integrated 11 articles, comprising seven quantitative studies, two qualitative studies, and two case reports. The findings did not indicate a significant improvement in end-of-life quality for individuals with dementia in the family meetings group compared to those receiving usual care. Limited evidence suggested some improvement in mental health outcomes for family caregivers. Both intervention and control groups incurred high care costs. However, family meetings appeared to delay nursing home placements for individuals with dementia. Two qualitative studies provided insights into the experiences of families and healthcare professionals participating in family meetings, highlighting opportunities and challenges in implementing such meetings. Additionally, two case reports offered specific and illustrative accounts of typical family meetings. CONCLUSION: Family meetings can delay nursing home placements for elderly individuals with dementia. Families dealing with dementia perceive family meetings as an opportunity to collaborate with professionals in providing comprehensive care. Further research is needed to explore the effectiveness of family meetings in decision-making for families affected by dementia. Additionally, addressing timing and process coordination issues in family meetings is crucial for optimising their practices among families dealing with dementia. RELEVANCE TO CLINICAL PRACTICE: In order to make family meetings more accessible to families of individuals with dementia, we offer the following recommendations for future research and practice: Rather than a blanket rejection, the decision regarding the participation of individuals with dementia in family meetings should be based on their specific condition and the needs of their family. Coordination and harmonisation of opinions and perceptions among family members of individuals with dementia can sometimes be complex for healthcare professionals. The involvement of family coordinators may simplify this process. To determine the optimal timing for holding family meetings that can better assist families dealing with dementia, we propose that the right to initiate a meeting be granted to the family. This allows them to convene with healthcare professionals and address their concerns at their convenience.

Modeling the CRL4A ligase complex to predict target protein ubiquitination induced by cereblon-recruiting PROTACs.

PROteolysis TArgeting Chimeras (PROTACs) are hetero-bifunctional small molecules that can simultaneously recruit target proteins and E3 ligases to form a ternary complex, promoting target protein ubiquitination and degradation via the Ubiquitin-Proteasome System (UPS). PROTACs have gained increasing attention in recent years due to certain advantages over traditional therapeutic modalities and enabling targeting of previously "undruggable" proteins. To better understand the mechanism of PROTAC-induced Target Protein Degradation (TPD), several computational approaches have recently been developed to study and predict ternary complex formation. However, mounting evidence suggests that ubiquitination can also be a rate-limiting step in PROTAC-induced TPD. Here, we propose a structure-based computational approach to predict target protein ubiquitination induced by cereblon (CRBN)-based PROTACs by leveraging available structural information of the CRL4A ligase complex (CRBN/DDB1/CUL4A/Rbx1/NEDD8/E2/Ub). We generated ternary complex ensembles with Rosetta, modeled multiple CRL4A ligase complex conformations, and predicted ubiquitination efficiency by separating the ternary ensemble into productive and unproductive complexes based on the proximity of the ubiquitin to accessible lysines on the target protein. We validated our CRL4A ligase complex models with published ternary complex structures and additionally employed our modeling workflow to predict ubiquitination efficiencies and sites of a series of cyclin-dependent kinases (CDKs) after treatment with TL12-186, a pan-kinase PROTAC. Our predictions are consistent with CDK ubiquitination and site-directed mutagenesis of specific CDK lysine residues as measured using a NanoBRET ubiquitination assay in HEK293 cells. This work structurally links PROTAC-induced ternary formation and ubiquitination, representing an important step toward prediction of target "degradability."

LINC02870 facilitates SNAIL translation to promote hepatocellular carcinoma progression.

Exploring the roles of long noncoding RNAs (lncRNAs) in tumorigenesis and metastasis could contribute to the recognition of novel diagnostic and therapeutic targets. LINC02870 is a novel lncRNA, whose role in tumors has not been reported. Herein, we focused on the function and mechanism of LINC02870 in human hepatocellular carcinoma (HCC). We first carried out a pan-cancer study of LINC02870 expression and its relationship to prognosis, and LINC02870 was determined to be a possible oncogene in HCC. Upregulated expressions of LINC02870 were also found in our HCC samples compared to the para-tumor samples. Moreover, overexpression of LINC02870 promoted the growth, migration, and invasion of HCC cells. Subsequently, binding proteins of LINC02870 were identified by a number of in silico analyses, including correlation analysis, signaling network analysis, and survival analysis. Intriguingly, the most promising binding protein of LINC02870 was predicted and confirmed to be eukaryotic translation initiation factor 4 gamma 1 (EIF4G1), an important component of the eukaryotic translation initiation factor 4F complex that initiates cap-dependent translation. Further investigation showed that LINC02870 increased the translation of SNAIL to induce malignant phenotypes in HCC cells. Additionally, HCC patients with higher expression levels of LINC02870 and EIF4G1 had shorter survival times than those with lower expression levels. Thus, our findings suggested that LINC02870 induced SNAIL translation and correlated with poor prognosis and tumor progression in HCC.

Microwave ablation vs. surgery for papillary thyroid carcinoma with minimal sonographic extrathyroid extension: a multicentre prospective study.

OBJECTIVES: Minimal extrathyroid extension (mETE) was removed from the TNM staging system. This study was designed prospectively to compare the safety and efficacy of microwave ablation (MWA) versus surgery for treating T1N0M0 papillary thyroid carcinomas (PTC) with sonographically detected mETE. METHODS: From December 2019 to April 2021, 198 patients with T1N0M0 mETE-PTCs evaluated by preoperative ultrasound from 10 hospitals were included. Ninety-two patients elected MWA, and 106 patients elected surgery for treatment. MWA was performed using extensive ablation with hydrodissection. Surgery consisted of lobectomy with ipsilateral central lymph node dissection (CLD), lobe and isthmus excision with ipsilateral CLD and total thyroidectomy with ipsilateral CLD. The rates of technical success, cost, oncologic outcomes, complications and quality of life of the two groups were assessed. RESULTS: The follow-up times for the MWA and surgery groups were 12.7 ± 4.1 and 12.6 ± 5.0 months, respectively. The technical success rate was 100% for both groups. Oncological outcomes of the two groups were similar during the follow-up (all p > 0.05). The MWA group had a shorter operation time, less blood loss and lower costs (all p < 0.001). Three complications (3.3%) were reported in the MWA group and 4 (3.8%) in the surgery group (p = 0.846). The surgery group had higher scores for scar problems and anxiety (p < 0.001 and p = 0.003, respectively). CONCLUSIONS: Microwave ablation was comparable in the short term to surgery in terms of treatment safety and efficacy in selected patients with T1N0M0 mETE-PTC detected by ultrasound. KEY POINTS: • Microwave ablation is comparable to surgery in the safety and short-term efficacy for PTCs with sonographically detected mETE. • Thermal ablation is technically feasible for mETE-PTC treatment. • Patients with mETE-PTC have similar quality of life in the two groups, except for worse scar problems and anxiety in the surgery group.

The effect of alginate oligosaccharides on intestine barrier function and Vibrio parahaemolyticus infections in the white shrimp Litopenaeus vannamei.

The intestine is a host-pathogen interaction site and improved intestinal barrier function help to prevent disease in shrimp. Alginate oligosaccharides (AOS) are derived from resourceful brown algae. The intestine protection properties of AOS were widely recognized, and their benefits in fish have been reported. Nevertheless, there are no reports on AOS in shrimp and other crustaceans. In the present work, we measured the effects of AOS on growth performance and disease resistance in the white shrimp Litopenaeus vannamei and investigated their effects on intestinal health. Shrimps with an initial weight of about 2 g were fed with diets supplemented with 0 (control), 0.07%, 0.2%, 0.6%, or 1.2% of AOS for 56 days and were sampled and challenged with Vibrio parahaemolyticus. Dietary AOS did not significantly influence weight gain or feed utilization (P > 0.05). However, AOS considerably decreased the seven-day cumulative mortality after the challenge at any dose (P < 0.05). Dietary AOS improved the intestinal structure, significantly boosted the intestinal villus height at 0.6% and 1.2% levels, and increased intestinal wall thickness by 0.2%, 0.6%, and 1.2%. The alkaline phosphatase and maltase activities were also increased, suggesting that AOS improved the intestinal condition. Redox homeostasis in intestinal was improved by AOS, as expressed by the enhanced total antioxidant capacity and decreased malonaldehyde content, partly due to the increased superoxide dismutase and catalase activities. Compared with the antioxidant system, AOS's stimulating effects on immunity were more significant. At any level, AOS significantly activated lysozyme activity, the expression of propo and two antimicrobial peptide genes (pen-3 and crusin). However, the lowest concentration of AOS did not stimulate the gene expression of all three assayed pattern recognition receptors (LGBP, Toll, and IMD), and only the highest concentration of AOS increased the expression of imd. These findings suggest that AOS are highly efficient immunostimulants, and various immune pathways in shrimp are differentially sensitive to AOS. Finally, our findings suggest that AOS significantly alter the gut microbiota and their relative abundance at the phylum, family, and genus levels. In conclusion, AOS significantly enhances disease resistance in L. vannamei, possibly attributed to improved intestinal development, increased intestinal immunity and altered microbiota. These findings could provide a basis for future studies on the practical use of AOS and its mechanisms of action.

The experiences of adolescents and young adults with epilepsy: A systematic review and meta-synthesis of qualitative studies.

BACKGROUND: Epilepsy is one of the most common and severe chronic neurological disorders and is associated with psychosocial problems. Several qualitative studies have investigated the experiences of adolescents and young adults with epilepsy. However, the findings were conflicting to some extent. This study examined and synthesized qualitative research data to understand the experiences of adolescents and young adults living with epilepsy, improving the development of targeted interventions and enhancing these experiences. OBJECTIVE: To synthesize qualitative evidence about the experiences of adolescents and young adults suffering from epilepsy. METHODS: This systematic review and qualitative evidence synthesis used the Joanna Briggs methodology for qualitative systematic reviews [1]. PubMed, PsychINFO, EMBASE, and Web of Science were searched for studies indexed until March 2022. Qualitative data were extracted, analyzed, and aggregated using meta-synthesis. RESULTS: Seventeen studies were included in the review. Three distinct themes were identified: "impact of epilepsy," "emotions associated with epilepsy," and "self-management of epilepsy." The results show that adolescents and young adults with epilepsy develop different strategies to manage epilepsy and associated problems. CONCLUSION: The results improved our understanding of the experiences of adolescents and young adults suffering from epilepsy. Several approaches are encouraged to improve these experiences and the quality of life, including granting more autonomy to affected children, providing individualized care and advice, improving public awareness of epilepsy to avoid stigma, and strengthening legal frameworks to safeguard the rights of affected people.

The relationship between tissue differentiation-inducing non-protein coding RNA expression and tumor size in patients with breast cancer.

Cancer is one of the leading causes of human death worldwide. One of the most common types of malignancy among women is breast cancer, which is the third most common cancer in the world after lung and stomach cancer. This study aimed to evaluate the expression level of Tissue Differentiation-Inducing Non-Protein Coding RNA (TINCR) in adjacent tumor and non-tumor tissues of 60 women with invasive ductal breast cancer. The relationship between TINCR expression and the clinical characteristics of patients has also been studied. For this purpose, total RNA was isolated from breast cancer patients' adjacent tumor and non-tumor tissue. RT Prime Script reagent was then used to convert total RNA to cDNA. The qRT-PCR quantified the TINCR expression level and analyzed the results by paired t-test. In addition, ROC curve analysis was used to evaluate the biomarker power of TINCR in breast cancer tumor tissues. According to the results, a decrease in the level of TINCR was obtained in the tumor tissue of breast cancer patients compared to the adjacent non-tumor tissue (P<0.001). TINCR expression was negatively correlated with tumor size and lymph node metastasis in breast cancer tumor tissue. In general, the decrease in the expression level of TINCR in the tumor tissue of breast cancer patients shows that its expression level can differentiate the adjacent tumor and non-tumor tissue from each other. In addition, TINCR has a lower expression level in breast cancer patients with large tumors, lymph node metastasis, and luminal subgroups A and B.

LncRNA CRNDE promotes cell proliferation, migration and invasion of ovarian cancer via miR-423-5p/FSCN1 axis.

Ovarian cancer seriously threatens the health of women. LncRNA CRNDE is known to be upregulated in ovarian cancer. However, the mechanism by which CRNDE regulates the progress of ovarian cancer is largely unknown. MTT assay was applied to measure the cell viability. Colony formation assay was used to measure the cell proliferation. Cell migration was tested by wound healing, and Transwell assay was performed to detect cell invasion. In addition, the expression of miR-423-5p, CRNDE and FSCN1 were detected by RT-qPCR and western blotting, respectively. Meanwhile, dual-luciferase reporter assay and RIP assay were performed to explore the correlation between miR-423-5p and CRNDE (or FSCN1). CRNDE and FSCN1 were upregulated in ovarian cancer cells (SKOV3, CAOV-3, IGROV1, A2780 and C13K), while miR-423-5p was downregulated. Moreover, silencing of FSCN1/CRNDE significantly decreased proliferation, migration and invasion of ovarian cancer cells (SKOV3 and CI3K) via suppressing MMP-2 and MMP-9. In addition, CRNDE could sponge miR-423-5p, and FSCN1 was confirmed to be the direct target of miR-423-5p. Furthermore, CRNDE knockdown-induced inhibition of FSCN1 was notably reversed by miR-423-5p downregulation. Knockdown of CRNDE inhibited cell proliferation, migration and invasion of ovarian cancer via miR-423-5p/FSCN1 axis. Thus, CRNDE may serve a new target for ovarian cancer.

Evaluate Short-Term Outcomes of abciximab in ST-Segment Elevation Myocardial Infarction Patients Undergoing Percutaneous Coronary Intervention: A Meta-Analysis of Randomized Clinical Trials.

Objectives: This meta-analysis was to verify the short-time efficacy and safety of abciximab in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). Background: Abciximab has long-term efficacy in patients with STEMI undergoing PCI, but the short-term efficacy is still controversial. Methods: We conducted a systematic review and meta-analysis compared with or without abciximab in patients with STEMI undergoing PCI. The relevant randomized controlled trials were included by searching PubMed, EMBASE, Cochrane Library, and Web of Science databases and other sources. The relative risk (RR) and 95% confidence intervals (CI) of outcomes were calculated by the fixed-effects model. Results: Ten randomized controlled trials with 5008 patients met inclusion criteria. There were no significant differences in risk of all-cause death at 30-day (RR 0.79, CI 0.55-1.12, P=0.18), major bleeding (1.37, 0.93-2.03, P=0.11), and transfusion (1.23, 0.94-1.61, P=0.13) between the two groups. However, there were significant differences in risk of all-cause death at 6 months (0.57, 0.36-0.90, P=0.02), recurrent myocardial infarction (0.55, 0.33-0.92, P=0.02), repeat revascularization (0.58, 0.43-0.78, P=0.0004), final TIMI flow <3 (0.77, 0.62-0.96, P=0.02), minor bleeding (1.29, 1.02-1.63, P=0.04), and thrombocytopenia (2.04, 1.40-2.97, P=0.0002). Conclusions: The application of abciximab can lead to a lower risk of reinfarction, revascularization, and all-cause death at 6 months, but a higher risk of minor bleeding, and thrombocytopenia.

Dual Antiplatelet Therapy After Drug-Eluting Stents Implantation in East Asians: A Network Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: Dual antiplatelet therapy (DAPT) is essential to prevent the risk of ischemia events, but it is difficult to avoid concurrent bleeding events. East Asians are associated with a higher tendency of bleeding than Caucasians, which may affect the DAPT duration. Therefore, this network meta-analysis to explore optimum DAPT duration for East Asians. The related randomized controlled trials that compared the different DAPT duration in East Asian patients were included by searching PubMed, EMBASE, and Cochrane Library database. The outcomes included myocardial infarction, stent thrombosis, all-cause death, stroke, and major bleeding. In addition, net adverse cardiac and cardiovascular events was defined as a composite outcome in this study. We calculated the odds ratio (OR) and 95% confidence intervals for end point events by the fixed effects model in the Bayesian's network frame. We included a total of 12 randomized controlled trials with 30,640 patients. Compared with 12-month DAPT, 1- to 3-month DAPT is effective in myocardial infarction (OR 0.72, 0.46-1.08), stents thrombosis (OR 1.27, 0.59-2.84), all-cause death (OR 0.91, 0.65-1.28), and stroke (OR 0.89, 0.57-1.39). The 1- to 3-month DAPT was associated with a lower risk of major bleeding compared with 12-month DAPT (OR 0.55, 0.4-0.76), 6-month DAPT (OR 0.54, 0.31-0.94), and >12-month DAPT (OR 0.43, 0.28-0.65). In addition, more than 12 months of DAPT did not reduce the incidence of myocardial infarction (OR 0.75, 0.51-1.11) and increased the risk of major bleeding (OR 1.28, 0.88-1.87) compared with 12-month DAPT. The 1- to 3-month DAPT was more secure and effective than the other 3 DAPT strategies. Although East Asians have a higher risk of bleeding, more than 12 months of DAPT does not increase this incidence of major bleeding.

Efficacy and Safety of Proton Pump Inhibitors in Patients With Coronary Artery Diseases Receiving Oral Antiplatelet Agents and/or Anticoagulants: A Systematic Review and Meta-Analysis.

ABSTRACT: The purpose of this meta-analysis was to evaluate the efficacy and safety of proton pump inhibitors (PPIs) plus antithrombotic strategy in patients with coronary artery diseases compared with antithrombotic strategy alone. We searched PubMed, EMBASE, Cochrane Library, and Chinese Biomedical Medical Literature databases to retrieve randomized controlled trials investigating PPIs combined with antithrombotic strategy in coronary artery diseases. The primary efficacy outcome was major adverse cardiovascular and cerebrovascular events (MACCE). The primary safety outcome was gastrointestinal events. Secondary outcomes included all-cause death, cardiovascular death, myocardial infarction, stent thrombosis, significant bleeding from gastroduodenal lesions, and gastroduodenal ulcer. Overall, 43,943 patients were enrolled from 19 trials. The incidence of MACCE [relative risk (RR) 1.05; 95% confidence interval (CI) 0.96-1.15], all-cause death (RR 0.84; 95% CI 0.69-1.01), cardiovascular death (RR 0.88; 95% CI 0.69-1.12), myocardial infarction (RR 0.98; 95% CI 0.88-1.09), stent thrombosis (RR 1.01; 95% CI 0.76-1.34), and gastroduodenal ulcer (RR 0.40; 95% CI 0.13-1.29) did not increase significantly in patients receiving PPIs compared with patients without those. There were significant differences in the risk of gastrointestinal events (RR 0.34; 95% CI 0.21-0.54) and significant bleeding from gastroduodenal lesions (RR 0.09; 95% CI 0.03-0.28) between the 2 groups. In patients with coronary artery diseases, PPIs plus antithrombotic strategy could reduce the risk of gastrointestinal events and significant bleeding from gastroduodenal lesions but may not affect the incidence of MACCE, all-cause death, cardiovascular death, myocardial infarction, stent thrombosis, and gastroduodenal ulcer (PROSPERO: CRD42021277899, date of registration October 10, 2021).

Efficacy and Safety of De-escalation of Antiplatelet Therapy After Percutaneous Coronary Intervention in Patients With Acute Coronary Syndrome: A Meta-Analysis of Randomized Clinical Trials.

ABSTRACT: Considering that there is no definite conclusion on the efficacy and safety of switching from potent P2Y 12 inhibitors to clopidogrel, we conducted a systematic review and meta-analysis of patients with acute coronary syndromes undergoing percutaneous coronary intervention and compared the efficacy and safety of de-escalation or not of antiplatelet therapy. The relevant randomized controlled trials were included by searching several databases. Net adverse clinical events were identified as the composite end point, which was defined as a composite of cardiovascular death, myocardial infarction, revascularization, stroke, and bleeding at 12 months after acute coronary syndromes. The efficacy end points were cardiovascular death, myocardial infarction, revascularization, stroke, all-cause death, and stent thrombosis. Bleeding was designed as the safety end point. The risk ratio and 95% confidence intervals of end point events were calculated by the fixed-effects model. Six randomized controlled trials with 7627 patients met inclusion criteria. There were significant differences in the risk of net adverse clinical events (RR, 0.67, CI, 0.58-0.78, P < 0.00001) and bleeding end point (0.61, 0.52-0.71, P < 0.00001) between the 2 groups. However, there were no significant differences in the risk of all efficacy end points. In general, the strategy of de-escalation from prasugrel or ticagrelor to clopidogrel can reduce the incidence of net adverse clinical events and bleeding events in patients with ACS undergoing percutaneous coronary intervention.

Comparison of Ticagrelor With Clopidogrel in East Asian Patients With Acute Coronary Syndrome: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

ABSTRACT: The risk of bleeding is high in East Asians, whether East Asian patients with acute coronary syndrome choose ticagrelor or clopidogrel is still controversial. In this study, PubMed, EMBASE, Cochrane Library database, and other sources were systematically searched. The primary efficacy outcome was all-cause death, the primary safety outcomes were any bleeding, PLATO major bleeding, and fatal bleeding. The secondary outcomes included vascular-cause death, myocardial infarction, stent thrombosis, stroke, and dyspnea. A total of 8 randomized controlled trials with 3597 patients met inclusion criteria. Compared with clopidogrel, ticagrelor had significantly higher incidence of any bleeding [risk ratio (RR), 1.63; 1.33-1.99; P < 0.00001], PLATO major bleeding (RR 1.56; 1.15-2.12; P = 0.004), and dyspnea (RR 2.60; 1.68-4.00; P < 0.00001). However, ticagrelor was associated with a significantly reduced risk of stent thrombosis (RR 0.42; 0.19-0.92; P = 0.03). There was no significant difference in the risk of all-cause death (RR 0.87; 0.64-1.24; P = 0.44), fatal bleeding (RR 2.49; 0.79-7.86; P = 0.12), vascular-cause death (RR 0.88; 1.60-0.30; P = 0.52), myocardial infarction (RR 0.89; 0.65-1.23; P = 0.49), and stroke (RR 0.84; 0.47-1.50; P = 0.56) between the 2 groups. The present findings demonstrated that ticagrelor was associated with a higher risk of any bleeding, PLATO major bleeding, and dyspnea compared with clopidogrel in East Asian patients with acute coronary syndrome. However, it significantly reduced the risk of stent thrombosis. (Registered by PROSPERO, CRD42021255215).

Safety and efficacy of anti-inflammatory therapy in patients with coronary artery disease: a systematic review and meta-analysis.

BACKGROUND: The inflammation hypothesis of atherosclerosis has been put forward for more than 20 years. Although many animal experiments have suggested that anti-inflammatory therapy can inhibit the atherosclerotic process, the efficacy of anti-inflammatory therapy for patients with coronary artery disease (CAD) is still controversial. Therefore, this study aims to evaluate the safety and efficacy of anti-inflammatory drugs in patients with CAD. METHOD: We conducted this systematic review and meta-analysis of randomized controlled trials by searching PubMed, EMBASE, web of science, and Cochrane Library database. The primary outcome was a composite outcome of cardiovascular death, myocardial infarction (MI), or stroke. The secondary outcomes included individual MI, coronary revascularization, cardiovascular death, all-cause death, and stroke. The relative risk (RR) and 95% confidence intervals (CI) for outcome events were calculated by the fixed effects model, and trial sequential analysis was applied to assess the results. RESULT: A total of ten randomized controlled trials and 60,782 patients with CAD was included. Compared with patients receiving placebo, anti-inflammatory therapy significantly reduced the incidence of the primary outcome in patients with CAD (RR 0.93, 0.89-0.98, P = 0.007). In addition, the anti-inflammatory therapy can also reduce the risk of MI (RR 0.90, 0.84-0.96, P = 0.002) and coronary revascularization (RR 0.74, 0.66-0.84, P < 0.00001) remarkably. However, there was no significant difference in the incidence of cardiovascular death (RR 0.94, 0.86-1.02, P = 0.14), all-cause death (RR 1.00, 0.94-1.07, P = 0.98) and stroke (RR 0.96, 0.85-1.09, P = 0.51) between two groups. CONCLUSIONS: Anti-inflammatory therapy can reduce the incidence of the primary outcome in patients with CAD, especially the risk of MI and coronary revascularization. However, anti-inflammatory therapy increases the risk of infection. (Registered by PROSPERO, CRD 420212291032).

Efficacy of intravascular imaging-guided drug-eluting stent implantation: a systematic review and meta-analysis of randomized clinical trials.

BACKGROUND: Traditional angiography only displays two-dimensional images of the coronary arteries during stent implantation. However, intravascular imaging can show the structure of the vascular wall, plaque characteristics. This article aims to evaluate the efficacy of intravascular imaging-guided drug-eluting stent (DES) implantation. METHOD: We conducted a systematic review and meta-analysis of randomized controlled trials of intravascular imaging-guided, including patients with DES implantation guided by intravascular ultrasound or optical coherence tomography and traditional angiography. The databases of PubMed, EMBASE, web of science, and Cochrane Library were searched. The primary outcome was target lesion revascularization (TLR). The secondary outcomes included the target vessel revascularization (TVR), myocardial infarction (MI), stent thrombosis (ST), cardiac death, all-cause death, and the major adverse cardiac events (MACE) during the 6-24 months follow-up. The fixed-effects model was used to calculate the relative risk (RR) and 95% confidence interval of the outcome event. Meanwhile, the trial sequence analysis was employed to evaluate the results. RESULT: This meta-analysis included fourteen randomized controlled trials with 7307 patients. Compared with angiography-guided, intravascular imaging-guided DES implantation can significantly reduce the risk of TLR (RR 0.63, 0.49-0.82, P = 0.0004), TVR (RR 0.66, 0.52-0.85, P = 0.001), cardiac death (RR 0.58; 0.38-0.89; P = 0.01), MACE (RR 0.67, 0.57-0.79; P < 0.00001) and ST (RR 0.43, 0.24-0.78; P = 0.005). While there was no significant difference regarding MI (RR 0.77, 0.57-1.05, P = 0.10) and all-cause death (RR 0.87, 0.58-1.30, P = 0.50). CONCLUSIONS: Compared with angiography, intravascular imaging-guided DES implantation is associated with better clinical outcomes in patients with coronary artery disease, especially complex lesions (Registered by PROSPERO, CRD 42021289205).

Real-time augmented reality application in presurgical planning and lesion scalp localization by a smartphone.

OBJECTIVE: A smartphone augmented reality (AR) application (app) was explored for clinical use in presurgical planning and lesion scalp localization. METHODS: We programmed an AR App on a smartphone. The accuracy of the AR app was tested on a 3D-printed head model, using the Euclidean distance of displacement of virtual objects. For clinical validation, 14 patients with brain tumors were included in the study. Preoperative MRI images were used to generate 3D models for AR contents. The 3D models were then transferred to the smartphone AR app. Tumor scalp localization was marked, and a surgical corridor was planned on the patient's head by viewing AR images on the smartphone screen. Standard neuronavigation was applied to evaluate the accuracy of the smartphone. Max-margin distance (MMD) and area overlap ratio (AOR) were measured to quantitatively validate the clinical accuracy of the smartphone AR technique. RESULTS: In model validation, the total mean Euclidean distance of virtual object displacement using the smartphone AR app was 4.7 ± 2.3 mm. In clinical validation, the mean duration of AR app usage was 168.5 ± 73.9 s. The total mean MMD was 6.7 ± 3.7 mm, and total mean AOR was 79%. CONCLUSIONS: The smartphone AR app provides a new way of experience to observe intracranial anatomy in situ, and it makes surgical planning more intuitive and efficient. Localization accuracy is satisfactory with lesions larger than 15 mm.

Efficacy and Safety of Short-Term Dual Antiplatelet Therapy in East Asians: A Systematic Review and a Meta-Analysis of Randomized Clinical Trials.

ABSTRACT: The optimal duration of dual antiplatelet therapy (DAPT) for patients implanted with new-generation drug-eluting stents in East Asians is currently still controversial. The purpose of this meta-analysis was to investigate the efficacy and safety of short-term DAPT in patients with those. In this study, randomized controlled trials from PubMed, EMBASE, and Cochrane Library were searched to compare the efficacy and safety of short-term DAPT (6 months or less) with long-term DAPT (12 months or more) in patients implanted with new-generation drug-eluting stents in East Asian from inception to September 2020. The primary efficacy outcome was all-cause death, the primary safety outcome was major bleeding, and the secondary outcomes included cardiovascular death, myocardial infarction, definite or possible stent thrombosis, and stroke. A total of 6 randomized controlled trials with 15,688 patients met inclusion criteria; there were no significant differences in the incidence of all-cause death [risk ratio (RR), 1.03; 0.76-1.39; P = 0.856)], cardiovascular death (RR, 0.83; 0.55-1.24; P = 0.361), myocardial infarction (RR, 0.97; 0.72-1.31; P = 0.853), definite or possible stent thrombosis (RR, 1.52; 0.83-2.78; P = 0.170), and stroke (RR, 0.90; 0.61-1.31; P = 0.574) between short-term and long-term DAPTs. However, there was a significant difference in the risk of major bleeding (RR, 0.64; 0.49-0.85; P = 0.002) between the 2 groups. Compared with long-term DAPT, the short-term DAPT can reduce the risk of major bleeding without increasing the risk of death or ischemia for East Asians (Registered by PROSPERO, CRD42020213266).
