Causal Association Between Allergic Diseases and Dementia: Evidence from Multivariate Mendelian Randomization Study.

Background: The link between allergic diseases and dementia remains controversial, and the genetic causality of this link is unclear. Objective: This study investigated the causal relationship between allergic diseases and dementia using univariate and multivariate Mendelian randomization (MR) methods. Methods: We selected genome-wide association studies including 66,645 patients with allergic diseases and 12,281 patients with dementia, with statistical datasets derived from the FinnGen Consortium of European origin. After a rigorous screening process for single nucleotide polymorphisms to eliminate confounding effects, MR estimation was performed mainly using the inverse variance weighting method and the MR-Egger method. Sensitivity analyses were performed using Cochran's Q test, MR-PRESSO test, MR Pleiotropy residuals and leave-one-out analysis. Results: Univariate and multivariate MR together demonstrated a causal relationship between atopic dermatitis and reduced vascular dementia (VaD) risk (OR = 0.89, 95% CI: 0.81-0.99, p = 0.031; OR = 0.85, 95% CI: 0.76-0.95, p = 0.003). MVMR confirmed asthma was associated with a reduction in the risk of Alzheimer's disease (AD) (OR = 0.82, 95% CI: 0.71-0.94, p = 0.005) and may be associated with a reduction in the risk of VaD (OR = 0.80, 95% CI: 0.65-0.99, p = 0.042); allergic rhinitis may be causally associated with an increased risk of AD (OR = 1.16, 95% CI: 1.00-1.35, p = 0.046) and VaD (OR = 1.29, 95% CI: 1.03-1.62, p = 0.027). In sensitivity analyses, these findings were reliable. Conclusions: MR methods have only demonstrated that allergic rhinitis dementia is associated with an increased risk of developing dementia. Previously observed associations between other allergic diseases and dementia may be influenced by comorbidities and confounding factors rather than causality.

Emerging role of mesenchymal stem cells-derived extracellular vesicles in vascular dementia.

Vascular dementia (VD) is a prevalent cognitive disorder among the elderly. Its pathological mechanism encompasses neuronal damage, synaptic dysfunction, vascular abnormalities, neuroinflammation, and oxidative stress, among others. In recent years, extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) have garnered significant attention as an emerging therapeutic strategy. Current research indicates that MSC-derived extracellular vesicles (MSC-EVs) play a pivotal role in both the diagnosis and treatment of VD. Thus, this article delves into the recent advancements of MSC-EVs in VD, discussing the mechanisms by which EVs influence the pathophysiological processes of VD. These mechanisms form the theoretical foundation for their neuroprotective effect in VD treatment. Additionally, the article highlights the potential applications of EVs in VD diagnosis. In conclusion, MSC-EVs present a promising innovative treatment strategy for VD. With rigorous research and ongoing innovation, this concept can transition into practical clinical treatment, providing more effective options for VD patients.

Global Research Trends and Hotspots for Ferroptosis, Necroptosis, and Pyroptosis in Alzheimer's Disease from the Past to 2023: A Combined Bibliometric Review.

Background: Alzheimer's disease (AD) is a genetically intricate neurodegenerative disorder. Studies on "Ferroptosis in AD", "Pyroptosis in AD", and "Necroptosis in AD" are becoming more prevalent and there is increasing evidence that they are closely related to AD. However, there has not yet been a thorough bibliometrics-based investigation on this subject. Objective: This study uses a bibliometric approach to visualize and analyze the literature within the field of three distinct types of cell death in AD and explores the current research hotspots and prospective research directions. Methods: We collected relevant articles from the Web of Science and used CiteSpace, VOS viewer, and Pajek to perform a visual analysis. Results: A total of 123, 95, and 84 articles were published in "Ferroptosis in AD", "Pyroptosis in AD", and "Necroptosis in AD", respectively. Based on keywords analysis, we can observe that "oxidative stress" and "lipid peroxidation", "cell death" and "activation", and "Nlrp3 inflammasome" and "activation" were the three most prominent words in the field of "Ferroptosis in AD", "Pyroptosis in AD", and "Necroptosis in AD", respectively. Focusing on the breakout words in the keyword analysis, we reviewed the mechanisms of ferroptosis, pyroptosis, and necroptosis in AD. By mapping the time zones of the keywords, we speculated on the evolutionary trends of ferroptosis, pyrotosis, and necroptosis in AD. Conclusions: Our findings can help researchers grasp the research status of three types of cell death in AD and determine new directions for future research as soon as possible.

According to the analysis of keywords and the frequency of citations, ncRNAs, transcription factor, genome, histone modification, blood DNA methylation, acetylation, biomarkers were hot research directions in AD today. Conclusion: According to bibliometric analysis, epigenetic research in AD was a promising research direction, and epigenetics had the potential to be used as AD biomarkers and therapeutic targets.

Transarterial Chemoembolization Plus Sorafenib versus Transarterial Chemoembolization Alone for Advanced Hepatocellular Carcinoma: An Umbrella Review of Meta-Analyses and Systematic Reviews.

Background: Sorafenib is the standard treatment for most cases of advanced hepatocellular carcinoma (HCC), based on Western and Eastern clinical guidelines. Thus, an increasing number of transarterial chemoembolization (TACE) plus sorafenib combination therapies have been used in clinical practice. In addition, several systematic reviews and meta-analyses have explored the efficacy and safety of the combination of TACE and sorafenib. Therefore, we performed an umbrella review to summarize and evaluate these evidence-based studies. Methods: PubMed, Embase, Cochrane Library, and Web of Science databases were searched up to June 1, 2023. All meta-analyses that evaluated the effect of TACE plus sorafenib on HCC were considered eligible. The quality of the included meta-analyses was evaluated by AMSTAR2 (A Measurement Tool to Assess Systematic Reviews). The quality of evidence per association provided in the meta-analyses was rated using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE). This study was registered with PROSPERO (Registration ID: CRD42023420417). Results: We included 12 meta-analyses, including randomized clinical trials, cohort studies, and observational studies. A total of 44 associations with overall survival, survival rate, time to disease progression, overall response rate, disease control rate, and adverse events were evaluated in this umbrella review. The quality of most associations ranged from low to very low, indicating that flaws were significant in the current meta-analyses. Conclusion: This umbrella review identified beneficial associations between TACE and sorafenib combination therapy in advanced HCC. However, owing to the low certainty of the evidence, clinicians should interpret our results with caution when applying them in clinical practice, and high-quality studies are required in the future to confirm our results.

Diagnostic performance of prediction models for extraprostatic extension in prostate cancer: a systematic review and meta-analysis.

PURPOSE: In recent decades, diverse nomograms have been proposed to predict extraprostatic extension (EPE) in prostate cancer (PCa). We aimed to systematically evaluate the accuracy of MRI-inclusive nomograms and traditional clinical nomograms in predicting EPE in PCa. The purpose of this meta-analysis is to provide baseline summative and comparative estimates for future study designs. MATERIALS AND METHODS: The PubMed, Embase, and Cochrane databases were searched up to May 17, 2023, to identify studies on prediction nomograms for EPE of PCa. The risk of bias in studies was assessed by using the Prediction model Risk Of Bias ASsessment Tool (PROBAST). Summary estimates of sensitivity and specificity were obtained with bivariate random-effects model. Heterogeneity was investigated through meta-regression and subgroup analysis. RESULTS: Forty-eight studies with a total of 57 contingency tables and 20,395 patients were included. No significant publication bias was observed for either the MRI-inclusive nomograms or clinical nomograms. For MRI-inclusive nomograms predicting EPE, the pooled AUC of validation cohorts was 0.80 (95% CI: 0.76, 0.83). For traditional clinical nomograms predicting EPE, the pooled AUCs of the Partin table and Memorial Sloan Kettering Cancer Center (MSKCC) nomogram were 0.72 (95% CI: 0.68, 0.76) and 0.79 (95% CI: 0.75, 0.82), respectively. CONCLUSION: Preoperative risk stratification is essential for PCa patients; both MRI-inclusive nomograms and traditional clinical nomograms had moderate diagnostic performance for predicting EPE in PCa. This study provides baseline comparative values for EPE prediction for future studies which is useful for evaluating preoperative risk stratification in PCa patients. CRITICAL RELEVANCE STATEMENT: This meta-analysis firstly evaluated the diagnostic performance of preoperative MRI-inclusive nomograms and clinical nomograms for predicting extraprostatic extension (EPE) in prostate cancer (PCa) (moderate AUCs: 0.72-0.80). We provide baseline estimates for EPE prediction, these findings will be useful in assessing preoperative risk stratification of PCa patients. KEY POINTS: • MRI-inclusive nomograms and traditional clinical nomograms had moderate AUCs (0.72-0.80) for predicting EPE. • MRI combined clinical nomogram may improve diagnostic accuracy of MRI alone for EPE prediction. • MSKCC nomogram had a higher specificity than Partin table for predicting EPE. • This meta-analysis provided baseline and comparative estimates of nomograms for EPE prediction for future studies.

Primary liposarcoma of the uterus with MDM2 negative.

ABSTRACT: Liposarcoma is one of the most common soft-tissue sarcomas that originates from adipose tissue. Primary uterine liposarcoma is extremely rare. With the MDM2, negative is even rarer. We report a 37-year-old woman presented with lower abdominal discomfort and increase in vaginal secretions for more than 2 months. The ultrasonography revealed a hypoechoic mass sized 81 × 73 × 67 mm in the right adnexal area. Histopathologically, the neoplasm was mainly composed of mature adipose tissue, a small number of scattered lipoblasts, and the spindle cell which with mild atypia. Immunohistochemistry showed that the tumor cells were positive for CDK4 but negative for MDM2, and FISH analysis showed no MDM2 amplification. The patient only underwent tumor excision and is currently doing well.

Increased Expression of INHBA Is Correlated With Poor Prognosis and High Immune Infiltrating Level in Breast Cancer.

Background: Inhibin, beta A (INHBA) is a member of the transforming growth factor-ß superfamily and is associated with carcinogenesis and cancer progression in several types of human cancers. However, its significance in breast cancer has not been evaluated. Here, we investigated the prognostic value of INHBA and its correlation with tumor-infiltration immune cells in the microenvironment of breast cancer. Methods: In this study, we analyzed the INHBA expression profile in the Oncomine database and Tumor Immune Estimation Resource 2.0 (TIMER2.0) site. Using Breast Cancer Gene-Expression Miner (bc-GenExMiner v4.7) tool and the UALCAN cancer database, we further evaluated the correlation of INHBA expression with clinicopathological factors in breast cancer. Then, we assessed the clinical prognostic value of INHBA using Kaplan-Meier Plotter and the PrognoScan databases. The correlations between INHBA and tumor-infiltrating immune cells were investigated via TIMER2.0. In addition, correlations between INHBA expression and gene markers of immune infiltrates were analyzed by TIMER2.0 and Gene Expression Profiling Interactive Analysis 2. Results: Compared with the level in normal tissues, the INHBA mRNA expression was upregulated in different subtypes of breast cancer, and its expression was positively correlated with progesterone receptor, human epidermal growth factor receptor-2 status, and PAM50 subtypes but negatively related to age and basal-like status. The INHBA protein was also highly expressed in primary breast cancer and closely related to the pathological stage. Patients with high INHBA expression levels showed worse overall survival, relapse-free survival, and distant metastasis-free survival. Also, high INHBA expression was significantly associated with worse overall survival and relapse-free survival in positive lymph nodes. Of interest, INHBA expression was negatively correlated with infiltrating levels of activated NK cells, NKT, and CD4+ T cells but was positively correlated with tumor infiltration of CD8+ T cells, neutrophils, especially macrophages and cancer-associated fibroblasts. Moreover, INHBA expression showed strong correlations with various markers of monocytes/macrophages and cancer-associated fibroblasts. Conclusion: High INHBA expression is correlated with poor prognosis and the infiltration of immune cells in the tumor microenvironment. These findings suggest that INHBA may be involved in immune escape and can serve as a potential biomarker of prognosis and tumor-infiltrating immune cells.

The effectiveness of distraction as preoperative anxiety management technique in pediatric patients: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Preoperative anxiety in pediatric patients can affect the course of surgery and cause adverse outcomes. Distraction is used as a measure to reduce preoperative anxiety in pediatric patients. OBJECTIVE: This study aimed to evaluate the effect of distraction on preoperative anxiety in pediatric patients. METHODS: We searched randomized controlled trials in databases (PubMed, Embase, Cochrane Library and ProQuest). Relevant studies were included by strict adherence to the inclusion and exclusion criteria, and intervention methods included a variety of distraction measures compared with routine care. The primary outcome was anxiety level after the intervention in holding area and (or) induction room measured by the modified Yale Preoperative anxiety Scale. Two researchers independently screened and extracted relevant data. A random-effects model was utilized to analysis the effect size as there was significant heterogeneity among the included studies. To further explore the reasons for potential heterogeneity and the effects of different distraction interventions, subgroup analysis was performed. RESULTS: Our search retrieved 793 records. 44 trials were included for qualitative analysis, of which 19 randomized controlled trials with 1341 patients were included for meta-analysis. Our study suggested a decreasing anxiety level of 5.34 versus 15.28 points respectively in holding area and induction room, where the distraction interventions group compared to the control group (MD: -5.34, 95% CI: -7.97 to -2.71 at holding aera; MD: -15.28, 95% CI: -21.48 to -9.09 at induction room). According to subgroup analysis, all subgroups showed significant effects of distraction on preoperative anxiety in pediatric patients. However, the heterogeneity between studies was high. CONCLUSION: Distraction as a preoperative anxiety management technique can benefit pediatric patients undergoing elective surgery, and healthcare personnel can apply preoperatively to alleviate preoperative anxiety in pediatric patients.

Transjugular Intrahepatic Portosystemic Shunt for Portal Vein Cavernous Transformation: A Systematic Review and Single-Arm Meta-Analysis.

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) is technically challenging in the treatment of portal vein cavernous transformation (PVCT), and there is no high-quality evidence regarding whether it is an option for patients with PVCT. We carried out a systematic review and meta-analysis to assess the feasibility and safety of TIPS for PVCT. METHODS: Systematic search of PubMed, Chinese National Knowledge Infrastructure (CNKI) database, Cochrane Library, Embase, and Wanfang database through December 2021 for appropriate studies reporting efficacy and safety in patients with PVCT undergoing TIPS. The main outcome included the technical success rate, postoperative rebleeding rate, postoperative hepatic encephalopathy rate, stent patency rate, preoperative, and postoperative portal pressure. RESULTS: Ten studies, including 292 patients were included. Our results showed that TIPS was technically successful in 82.97% (95% confidence interval [CI]: 77.14%-88.41%, p = 0.297) with low heterogeneity (I2 = 18.39%, p = 0.279). Postoperative rebleeding occurred in 9.56% (95% CI: 4.55%-16.77%, p = 0.073) with moderate heterogeneity (I2 = 46.45%, p = 0.06). Postoperative hepatic encephalopathy occurred in 18.55% (95% CI: 9.23%-27.05%, p = 0.343) with moderate heterogeneity (I2 = 48.62%, p = 0.049). Stent patency during follow-up was in 78.43% (95% CI: 70.74%-85.20%, p = 0.805) with low heterogeneity (I2 = 0%, p = 0.654). Postoperative portal pressure significantly reduced (WMD = 12.79 mm Hg, 95% CI: 12.09-13.48 mm Hg, p < 0.00001) with high heterogeneity (I2 = 61.4%, p = 0.02). Both Begg test and funnel plot showed that there was no significant publication bias. CONCLUSIONS: TIPS is feasible and safe in patients with PVCT and PVCT should not be considered an absolute contraindication to TIPS.

Accuracy of quantitative diffusion-weighted imaging for differentiating benign and malignant pancreatic lesions: a systematic review and meta-analysis.

BACKGROUND: A variety of imaging techniques can be used to evaluate diffusion characteristics to differentiate malignant and benign pancreatic lesions. The diagnostic performance of diffusion parameters has not been systematic assessed. PURPOSE: We aimed to investigate the diagnostic efficacy of quantitative diffusion-weighted imaging (DWI) for pancreatic lesions. METHODS: A literature search was conducted using the PubMed, Embase, and Cochrane Library databases for studies from inception to March 30, 2020, which involves the quantitative diagnostic performance of diffusion-weighted imaging (DWI) and intravoxel incoherent motion (IVIM) in the pancreas. Studies were reviewed according to inclusion and exclusion criteria. The quality of articles was evaluated by the Quality Assessment of Diagnostic Accuracy Studies-2 (QUATAS-2). A bivariate random-effects model was used to evaluate pooled sensitivities and specificities. Univariable meta-regression analysis was used to test the effects of factors that contributed to the heterogeneity. RESULTS: A total of 31 studies involving 1558 patients were ultimately eligible for data extraction. The lowest heterogeneity was found in specificity of perfusion fraction (f) with the I2 value was 17.97% and Cochran p value was 0.28. However, high heterogeneities were found for the other parameters (all I2 > 50%). There was no publication bias found in funnel plot (p = 0.30) for the apparent diffusion coefficient (ADC) parameter. The pooled sensitivities for ADC, f, pure diffusion coefficient (D), and pseudo diffusivity coefficient (D*) were 83%, 81%, 76%, and 84%, respectively. The pooled specificities for ADC, f, D, and D* were 87%, 83%, 69%, and 81% respectively. The areas under the curves for ADC, f, D, and D* were 0.92, 0.87, 0.79, and 0.87 respectively. CONCLUSION: Quantitative DWI and IVIM have a good diagnostic performance for differentiating malignant and benign pancreatic lesions. KEY POINTS: • IVIM has high sensitivity and specificity (84% and 83%, respectively) for differential diagnosis of pancreatic lesions, which is comparable to that of the ADC (83% and 87%, respectively). • The ADC has an excellent diagnostic performance for differentiating malignant from benign IPMNs (sensitivity, 0.83; specificity, 0.92); the f has the best diagnostic performance for differentiating pancreatic carcinoma from PNET (sensitivity, 0.85; specificity, 0.85). • For the ADC, using a maximal b value < 800 s/mm2 has a higher diagnostic accuracy than ≥ 800 s/mm2; performing in a high field strength (3.0 T) system has a higher diagnostic accuracy than a low field strength (1.5 T) for pancreatic lesions.

Genetic diversity, forensic feature, and phylogenetic analysis of Guizhou Tujia population via 19 X-STRs.

BACKGROUND: X-chromosome short tandem repeats (X-STRs) with unique sex-linkage inheritance models play a complementary role in forensic science. Guizhou is a multiethnic province located in southwest China and some genetic evidence focusing on X-STRs for various minorities was reported. However, population data of Guizhou Tujia are scarce. METHODS: A total of 507 Guizhou Tujia individuals were profiled using the AGCU X-19 STR kit. Allele frequencies and forensic parameters were calculated. Additionally, population genetic relationships between Guizhou Tujia and other 19 populations were explored. RESULTS: A total of 257 alleles with the allele frequencies ranged from 0.0013 to 0.6098 were found. The combined power of discrimination in males and females and mean exclusion chances in all case scenarios were all greater than 0.99999. Population comparisons showed Guizhou Tujia had a homogeneity with all Han populations from different administrative regions, and other ethnic populations residing in Guizhou, while had obviously genetic heterogeneity with the Altaic family populations except Xibe. CONCLUSION: Nineteen X-STRs can afford a reliable and informative database of Guizhou Tujia population for human identification and paternity testing, especially in complex biological relations. The genetic relationships of Chinese are significantly influenced by the geographic position and ethnolinguistic origin.

Uterine artery embolization versus hysterectomy in the treatment of refractory postpartum hemorrhage: a systematic review and meta-analysis.

Introduction: We carried out a systematic review and meta-analysis to assess the safety and effectiveness of uterine artery embolization (UAE) compared with conventional hysterectomy on refractory postpartum hemorrhage (PPH).Methods: We searched PubMed, Embase, Chinese National Knowledge Infrastructure database (CNKI), Cochrane Library, and Wanfang database through October 2017 for randomized controlled trials (RCTs) and observational studies assessing the safety and effectiveness of UAE compared with hysterectomy on refractory PPH. The main outcome measures included the blood loss, operating time, hemostatic effective rate, and length of stay.Results: Six RCTs and nine observational studies were included in the meta-analysis, which involved 1142 women with refractory PPH. The results demonstrated that UAE was more beneficial on refractory PPH compared with hysterectomy using four scales: blood loss (WMD 893.39 mL; 95% CI: -1205.65, -581.13; p < .001); operating time (WMD -37.19 minutes; 95% CI: -44.42, -29.96; p < .001); length of stay (WMD -5.36 days; 95% CI: -5.76, -4.97; p < .001), hemostatic effective rate (OR 1.58, 95% CI: 0.80, 3.12, p = .184) .Conclusions: In the present meta-analysis, the positive findings suggest UAE has beneficial effects on refractory PPH. UAE significantly reduced blood loss, shortened the operating time, and length of stay compared with hysterectomy. And there is no difference between the UAE group and hysterectomy group in hemostatic effective rate. However, those findings should be treated with caution because of heterogeneity and potential biases.

Efficacy and safety of recombinant human interleukin-11 in the treatment of acute leukaemia patients with chemotherapy-induced thrombocytopenia: A systematic review and meta-analysis.

RATIONALE, AIMS, AND OBJECTIVES: Current meta-analysis was conducted aiming to assess the efficacy and safety of recombinant human interleukin-11 (rhIL-11) in the treatment of acute leukaemia (AL) patients with chemotherapy-induced thrombocytopenia (CIT). METHODS: We searched PubMed, Embase, Chinese National Knowledge Infrastructure database (CNKI), Cochrane Library, and Wan Fang Database on 4 July 2018. RESULTS: Ten randomized controlled trials (RCTs) and two observational studies were included, which involved 754 AL patients with CIT. Pooled analysis demonstrated that rhIL-11 was beneficial on CIT: recovery time of platelet count to 50 × 109 /L [weight mean difference (WMD) = -4.19 days; 95% CI: -5.01, -3.37], recovery time of platelet count to 100 × 109 /L (WMD = -4.45 days; 95% CI: -4.85, -4.06), platelet transfusion volume (WMD = -6.14 U; 95% CI: -9.20, -3.09), and the rate of haemorrhage (RR = 0.46; 95% CI: 0.36 to 0.61). Most adverse events associated with rhIL-11 were mild to moderate. CONCLUSION: Our findings suggest that rhIL-11 is effective and safe in the treatment of CIT in patients with AL.

Relationship between mortality in people with mental disorders and suicide mortality in China during 2000 to 2014: An observational study.

Suicide is one of the top 10 causes of death in many countries. Although there are many studies on mental disorders, few studies have examined mortality in suicide population and mentally ill population. This study examined the association between mortality and mental disorders using data on suicides and mental disorders in China. Data from China's Health and Family Planning Statistical Yearbook for 2000 to 2014 were used to analyze the relationship between mortality associated with suicide and mental disorders. The analyses found that mortality among people with mental disorders dropped from 5.42/10 million in 2000 to 2.68/10 million in 2014, decreased more among females than males, and differed between urban and rural areas; that suicide mortality dropped from 10.79/10 million in 2000 to 6.79/10 million in 2014; the decrease was greater in women than in men, with suicide being highest among male residents of cities; and no significant correlation was found between mortality among persons with mental disorders and suicide mortality. There was no correlation between suicide mortality and mental-disorder mortality during 2000 to 2014; however, overall mortality decreased more among females than males during this period.
