Ablação por Cateter para Fibrilação Atrial em Pacientes com Fração de Ejeção do Ventrículo Esquerdo ≤ 45%: Uma Metanálise de Ensaios Clínicos Randomizados / Catheter Ablation for Atrial Fibrillation in Patients with Left Ventricular Ejection Fraction ≤ 45%: A Meta-Analysis of Randomized Controlled Trials

Resumo Fundamento A fibrilação atrial (FA) e a insuficiência cardíaca (IC) coexistem frequentemente, resultando em desfechos adversos. No entanto, permanecem controvérsias quanto à eficácia da ablação por cateter (AC) em pacientes com FA com disfunção ventricular esquerda grave. Objetivos O objetivo deste estudo foi realizar uma metanálise de ensaios prospectivos randomizados e controlados para avaliar a eficácia da AC versus terapia médica (TM) em pacientes com FA com fração de ejeção do ventrículo esquerdo (FEVE) ≤45%. Métodos Procuramos na literatura estudos que comparassem AC com TM em pacientes com FA com FEVE ≤45%. Foi realizada uma metanálise de 7 ensaios clínicos, incluindo 1.163 pacientes com FA e IC. A análise de subgrupo foi realizada com base na FEVE basal. Todos os testes foram bilaterais; apenas o valor p <0,05 foi considerado estatisticamente significativo. Resultados Descobrimos que a AC estava associada a menor mortalidade por todas as causas (taxa de risco: 0,52, IC 95%: 0,37 a 0,72; p<0,01) e maiores melhorias na FEVE (diferença média: 4,80%, IC 95%: 2,29% a 7,31%; p<0,01) em comparação com TM. Os pacientes do grupo AC apresentaram menor risco de hospitalização por IC e recorrência de FA e qualidade de vida significativamente melhor do que aqueles do grupo TM. Os resultados da análise de subgrupo indicaram que pacientes com disfunção ventricular esquerda mais leve melhoraram a FEVE após a ablação de FA (diferença média: 6,53%, IC 95%: 6,18% a 6,88%; p<0,01) em comparação com pacientes com doença mais grave (diferença média : 2,02%, IC 95%: 0,87% a 3,16%; p<0,01). Conclusões Nossa metanálise demonstrou que a AC foi associada a melhorias significativas nos resultados de pacientes com FA com FEVE ≤45%. Além disso, pacientes com FA com disfunção ventricular esquerda mais leve poderiam se beneficiar mais com a AC.

Abstract Background Atrial fibrillation (AF) and heart failure (HF) frequently coexist, resulting in adverse outcomes. However, controversies remain regarding the efficacy of catheter ablation (CA) in AF patients with severe left ventricular dysfunction. Objectives The purpose of this study was to perform a meta-analysis of prospective randomized controlled trials to evaluate the efficacy of CA versus medical therapy (MT) in AF patients with left ventricular ejection fraction (LVEF) ≤45%. Methods We searched the literature for studies that compared CA to MT in AF patients with LVEF ≤45%. A meta-analysis of 7 clinical trials was performed, including 1163 patients with AF and HF. Subgroup analysis was performed based on baseline LVEF. All tests were 2-sided; only the p-value <0.05 was considered statistically significant. Results We found that CA was associated with lower all-cause mortality (risk ratio: 0.52, 95% CI: 0.37 to 0.72; p<0.01) and greater improvements in LVEF (mean difference: 4.80%, 95% CI: 2.29% to 7.31%; p<0.01) compared to MT. Patients in the CA group had a lower risk of HF hospitalization and AF recurrence and a significantly better quality of life than those in the MT group. The results of subgroup analysis indicated that patients with milder left ventricular dysfunction improved LVEF after AF ablation (mean difference: 6.53%, 95% CI: 6.18% to 6.88%; p<0.01) compared to patients with more severe disease (mean difference: 2.02%, 95% CI: 0.87% to 3.16%; p<0.01). Conclusions Our meta-analysis demonstrated that CA was associated with significant improvements in outcomes of AF patients with LVEF ≤45%. Additionally, AF patients with milder left ventricular dysfunction could benefit more from CA.

Psychological resilience and mood disorders: a systematic review and meta-analysis

Abstract Objective This systematic review aims to describe the relationship between psychological resilience and mood disorders. Methods This is a systematic review and meta-analysis. The following databases were searched on November 6, 2020: PubMed, PsycINFO, and Embase. Results Twenty-three articles were included and the majority of the studies included (95.7%) showed that psychological resilience has a positive impact in mood disorders. Our meta-analysis showed that individuals with bipolar disorder presented significantly lower levels of psychological resilience compared to controls (standardized mean difference [SDM]: -0.99 [95% confidence interval {95%CI}: -1.13 to -0.85], p < 0.001). In addition, individuals with depression had significantly lower levels of psychological resilience compared to controls (SDM: -0.71 [95%CI -0.81 to -0.61], p < 0.001). Conclusion Our results showed that individuals with mood disorders are less resilient than individuals without mood disorders. Our findings reinforce the importance of investigating interventions that may help to improve psychological resilience considering its positive impact in the context of mood disorders.

Objective@#To systematically evaluate the effect of mini basketball on children s upper limb strength in China, and to provide basis for the development of kindergarten mini basketball and the improvement of children s upper limb strength performance.@*Methods@#CNKI, Wanfang Data, VIP, PubMed, and Web of Science databases were searched from the establishment of the database to July 26, 2023. The PICOST model was used for literature screening, and 13 literature with a total of 20 studies were finally included. The Cochrane System Evaluation Criteria was used for literature quality evaluation. Review Manager 5.4 and Stata 17 were used for statistical analysis and publication bias test.@*Results@#A total of 939 children were included in 20 studies, including 470 in the experimental group and 469 in the control group. Meta analysis showed that mini basketball had an extremely significant effect on the improvement of children s upper limb strength ( SMD=0.83, 95%CI=0.53-1.13, Z=5.40, P < 0.01 ). The results of subgroup analysis showed that there was no significant gender difference in the improvement of children s upper limb strength by mini basketball ( P >0.05), mini basketball exercise with an intervention time of less than or equal to 30 minutes ( SMD=0.49, 95%CI=0.29-0.70, Z=4.70, P <0.01) and an exercise cycle of more than 12 weeks ( SMD=1.25, 95%CI=0.54-1.96, Z= 3.45 , P<0.01) can achieve a better intervention effect on the upper limb strength of children. Meta regression results showed that the exercise intervention time was the main source of heterogeneity ( t=2.71, 95%CI= 1.38-22.93, P <0.05). Egger s test showed that the publication bias of the included studies was not statistically significant ( t=0.78, P >0.05).@*Conclusions@#Mini basketball training can improve the upper limb strength of children, but there is no significant gender difference. The upper limb strength is affected by the restriction of intervention time and exercise cycle. Schools can appropriately add small basketball in physical education classes to improve children s upper limb strength.

Risk factors for postoperative pulmonary infection in lung cancer patients: A systematic review and meta-analysis / 中国胸心血管外科临床杂志

@#Objective    To systematically evaluate the risk factors for postoperative pulmonary infection in patients with lung cancer (PPILC), and to provide a theoretical reference for clinicians to prevent the occurrence of PPILC. Methods     The databases of CNKI, Wanfang data, VIP, CBM, PubMed, EMbase and The Cochrane Library were searched by computer to collect researches on the risk factors for PPILC. The search period was from 2012 to 2021. Two clinicians independently screened literature and extracted data and assessed studies for risk of bias, cross-checked and agreed. Meta-analysis was performed using RevMan 5.3 software. Results     A total of 25 studies were included, including 20 case-control studies, 1 cohort study, and 4 cross-sectional studies, covering 15 129 patients. Twenty case-control studies and 1 cohort study had Newcastle-Ottawa Scale (NOS) scores≥6 points, and 4 cross-sectional studies had the Agency for Health Care Quality and Research (AHRQ) scale scores≥6 points. The results of meta-analysis showed that the risk factors for PPILC included: (1) 4 patient's own factors: age≥60 years, male, smoking history, smoking index≥400; (2) 7 preoperative factors: suffering from diabetes, chronic heart failure and chronic obstructive pulmonary disease, the ratio of forced expiratory volume in 1 second to forced expiratory volume<70%, the ratio of forced expiratory volume in 1 second to the predicted value, preoperative airway colonization, non-standard use of prophylactic antibiotics before surgery; (3) 3 intraoperative factors: operation time≥3 h, thoracotomy, the number of resected lobe≥2; (4) 3 postoperative factors: postoperative pain, postoperative mechanical ventilation≥12 h, postoperative invasive operation. Large number of preoperative lymphocyte, intraoperative systematic lymph node dissection, TNM stage Ⅰ and Ⅱ, and enhanced recovery after surgery were protective factors for PPILC. Conclusion     The current research evidence shows that multiple factors are associated with the risk of PPILC. However, considering the influence of the quality and quantity of the included literature, the results of this study urgently need to be further verified by more high-quality clinical studies.

MethodsThis study was conducted according to the PRISMA guideline. English and Chinese databases including CNKI， Wanfang Data， VIP， CBM， the Cochrane Library， PubMed， Embase， and Web of Science were searched for clinical studies on omental wrapping technique for pancreaticojejunal anastomosis in preventing complications after pancreaticoduodenectomy published up to November 2022， and Stata 16 and Review Manager 5.4 were used to perform the meta-analysis. ResultsA total of 15 studies with 1 830 patients were included in this study. The meta-analysis showed that the omental wrapping group had a significantly lower overall incidence rate of postoperative pancreatic fistula （POPF） than the non-omental wrapping group （odds ratio ［OR］=0.30， 95% confidence interval ［CI］： 0.22‍ ‍—‍ ‍0.41， P<0.001）， and the subgroup analysis showed that the omental wrapping group had a significantly lower incidence rate of grade B/C POPF than the non-omental wrapping group （OR=0.29， 95%CI： 0.21‍ ‍—‍ ‍0.39， P<0.001）. Compared with the non-omental wrapping group， the omental wrapping group had significantly lower incidence rates of postoperative bile leakage （OR=0.30， 95%CI： 0.16‍ ‍—‍ ‍0.56， P<0.001）， postoperative hemorrhage （OR=0.35， 95%CI： 0.24‍ ‍—‍ ‍0.53， P<0.001）， delayed gastric emptying （OR=0.45， 95%CI： 0.31‍ ‍—‍ ‍0.64， P<0.001）， abdominal infection （OR=0.55， 95%CI： 0.40‍ ‍—‍ ‍0.75， P<0.001）， reoperation （OR=0.31， 95%CI： 0.18‍ ‍—‍ ‍0.54， P<0.001）， and death within 30 days after surgery （OR=0.42， 95%CI： 0.22‍ ‍—‍ ‍0.80， P=0.009）， a significantly earlier time to diet （mean difference ［MD］=-0.98， 95%CI： -1.84 to -0.11， P=0.03）， and a significantly shorter length of postoperative hospital stay （MD=-2.44， 95%CI： -4.10 to -0.77， P=0.004）. There were no significant differences between the two groups in the time of operation （MD=-13.68， 95%CI： -28.31 to -0.95， P=0.07） and intraoperative blood loss （MD=-17.26， 95%CI： -57.55 to -23.03， P=0.40）. ConclusionOmental wrapping can reduce the incidence rates of postoperative complications such as pancreatic fistula， bile leakage， postoperative hemorrhage， abdominal infection， and delayed gastric emptying， improve the prognosis of patients， and shorten the length of hospital stay， without increasing surgical difficulty or time of operation.

Efficacy of percutaneous transhepatic variceal embolization alone or in combination with partial splenic embolization in treatment of portal hypertensive hemorrhage in liver cirrhosis： A Meta-analysis / 临床肝胆病杂志

ObjectiveTo investigate the efficacy of percutaneous transhepatic variceal embolization （PTVE） alone or in combination with partial splenic embolization （PSE） in the treatment of portal hypertensive hemorrhage in liver cirrhosis through a meta-analysis. MethodsThis study was conducted according to PRISMA guideline， with a PROSPERO registration number of CRD42023396690. Wanfang Med Online， CNKI， CBM， VIP Databases， PubMed， Embase， the Cochrane Library， and Web of Science databases were searched for articles on PTVE alone or in combination with PSE in the treatment of portal hypertensive hemorrhage in liver cirrhosis published up to December 23， 2022. The articles were selected based on inclusion and exclusion criteria， and related data were extracted. The RevMan 5.4.1 statistical analysis software was used to perform the meta-analysis. ResultsEight articles were finally included， with a total sample size of 592 cases， among which there were 316 cases in the PTVE+PSE group and 276 cases in the PTVE group. The meta-analysis showed that compared with the PTVE group， the PTVE+PSE group had significantly lower postoperative portal vein pressure （standardized mean difference ［SMD］=-1.75， 95% confidence interval ［CI］： -2.33 to -1.16， P<0.05）， postoperative diameter of the portal vein （SMD=-0.87， 95%CI： -1.64 to -0.10， P<0.05）， postoperative rebleeding rate （odds ratio ［OR］=0.17， 95%CI： 0.11 — 0.28， P<0.05）， mortality rate （OR=0.13， 95%CI： 0.04 — 0.37， P<0.05）， and incidence rate of postoperative portal hypertensive gastrointestinal disease （OR=0.17， 95%CI： 0.07 — 0.45， P<0.05］， as well as a significantly higher postoperative platelet level （SMD=0.79， 95%CI： 0.52 — 1.06， P<0.05）， while there were no significant differences between the two groups in the incidence rates of postoperative ascites. ConclusionCompared with PTVE alone， PTVE combined with PSE can effectively reduce the rebleeding rate and mortality rate of portal hypertensive hemorrhage in liver cirrhosis， the incidence rate of portal hypertensive gastrointestinal disease， and portal vein pressure， and it can also shorten the diameter of the portal vein and increase platelet level. Therefore， it is an effective interventional method for the treatment of portal hypertension hemorrhage in liver cirrhosis.

Meta-analysis of Distribution Frequency of Traditional Chinese Medicine Syndrome in Primary Osteoporosis / 中国实验方剂学杂志

ObjectiveTo systematically evaluate the distribution of traditional Chinese medicine（TCM） syndromes of primary osteoporosis（POP） in China by using evidence-based medicine methods， and to understand the distribution law of the syndromes. MethodChina National Knowledge Infrastructure（CNKI）， VIP Chinese Science and Technology Journal Database（VIP）， WanFang Data Knowledge Service Platform（WanFang） and China Biology Medicine（CBM） were searched to obtain representative literature， and each database was searched from the 1994 World Health Organization defined diagnostic criteria for osteoporosis until May 1， 2023. Two researchers independently screened literature according to the criteria， extracted data， and cross-checked them. Meta analysis was conducted using R4.1.3， and subgroup analysis was performed. ResultA total of 56 Chinese papers were included， involving 14 415 patients. After standardized classification of syndromes， 11 articles were excluded， and Meta analysis results of the ultimately included 45 Chinese articles showed that the distribution frequencies of liver-kidney Yin deficiency syndrome， spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome in 12 723 patients were 27%［95% confidence interval（CI） 0.24-0.31］， 32%（95% CI 0.29-0.36）， 36%（95% CI 0.30-0.42）. Subgroup analysis showed that there was a statistically significant difference in the distribution of the three TCM syndromes in the north and south（P<0.05）. In addition， the incidence of TCM syndrome fractures in different types of POP was 15%（95% CI 0.09-0.24） for liver-kidney Yin deficiency syndrome， 20%（95% CI 0.12-0.30） for spleen-kidney Yang deficiency syndrome， and 31%（95% CI 0.25-0.39） for kidney deficiency and blood stasis syndrome. ConclusionThe distribution of syndromes in POP patients is mainly kidney deficiency， accompanied by liver and spleen dysfunction. Liver-kidney Yin deficiency syndrome， spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome are all the main syndromes of POP and osteoporotic fractures， and kidney deficiency and blood stasis syndrome is most closely related to the development of osteoporotic fractures. The reference standards for syndrome determination among the included studies are inconsistent， and in the future， it is necessary to focus on their determination standards to obtain consensus research results， at the same time， conduct large-scale syndrome research to obtain representative research results， providing a basis for clinical practice and research.

OBJECTIVE To compare the efficacy and safety of Saccharomyces boulardii and Bifidobacterium triple live bacteria in the treatment of pediatric diarrhea. METHODS Retrieved from PubMed， Embase， the Cochrane Library， CBM， Wanfang data， CNKI and VIP， randomized controlled trials （RCTs） about S. boulardii （S. boulardii group） versus Bifidobacterium triple liver bacteria （Bifidobacterium group） were collected. After screening the literature， extracting data and evaluating the quality， meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 9 RCTs were included， involving 898 patients. Results of meta-analysis showed there was no statistical significance in total response rate [OR＝1.69， 95%CI （0.93， 3.09）， P＝0.09]， duration of diarrhea [MD＝－1.39， 95%CI （－3.35， 0.57）， P＝0.16]， the time of abdominal pain disappearance [MD＝0.09， 95%CI（－0.87， 1.05），P＝0.86] or the incidence of adverse reactions [OR＝0.65， 95%CI （0.05， 8.03）， P＝0.74]. The number of stools in S. boulardii group was significantly less than Bifidobacterium group [MD＝－0.91， 95%CI （－1.80， －0.02）， P＝0.04]. The results of subgroup analysis showed that the duration of diarrhea in children with antibiotic-associated diarrhea in S. boulardii group was significantly shorter than Bifidobacterium group （P＜0.05）. CONCLUSIONS The efficacy and safety of S. boulardii are similar to those of Bifidobacterium in the treatment of diarrhea， but S. boulardii is better than Bifidobacterium in terms of stool number， the duration of diarrhea in children with antibiotic-associated diarrhea.

Meta-analysis of efficacy and safety of aspirin versus other anticoagulants in the prevention of thromboembolism after orthopedic surgery / 中国药房

OBJECTIVE To evaluate the clinical efficacy and safety of aspirin versus other anticoagulants in the prevention of thromboembolism after orthopedic surgery. METHODS Retrieved from PubMed， Embase， the Cochrane Library， CNKI， Wanfang data and VIP， randomized controlled trials （RCTs） and cohort studies about aspirin （trial group） versus other anticoagulants （control group） were collected during the inception and June 1st， 2023. After literature screening， data extraction and quality evaluation， the meta-analysis was conducted by using RevMan 5.4 software. RESULTS A total of 22 studies were included， involving 9 RCTs and 13 cohort studies. RCT results showed that the incidences of deep vein thrombosis （DVT） [RR＝1.81， 95%CI（1.36， 2.40）， P＜0.000 1] and postoperative pulmonary embolism （PE） [RR＝1.55， 95%CI（1.01， 2.40）， P＝0.05] in trial group were significantly higher than control group. There was no statistically significant difference in the incidences of postoperative massive bleeding， postoperative surgical site infection， all-cause death， or any bleeding after surgery between 2 groups. In the cohort study， the incidence of any bleeding in trial group was significantly lower than control group [RR＝0.71，95%CI （0.64， 0.79）， P＜0.000 1]， while the differences in other indicators were not statistically significant （P＞0.05）. The results of subgroup analysis based on different anticoagulants showed that in RCT， the incidences of DVT and PE after surgery in patients using low-molecular-weight heparin （LMWH） were significantly lower than using aspirin （P＜0.05）； in the cohort study， the incidences of DVT and PE after surgery were significantly lower in patients using direct oral anticoagulants （DOAC） than using aspirin （P＜0.05）. There was no statistically significant difference in the incidence of major bleeding between patients using aspirin and using DOAC and LWMH （P＞0.05） in both RCT and cohort study. CONCLUSIONS Aspirin is equally safe as other anticoagulants for the prevention of thromboembolism after orthopedic surgery， but its efficacy may not be as good as other anticoagulants. After orthopedic surgery， other anticoagulants should be preferred to prevent venous thromboembolism， and aspirin should be carefully considered.

Effect of severe weather on road traffic injuries：a meta-analysis / 公共卫生与预防医学

Objective To explore the impact of severe weather on road traffic injuries (RTIs). Methods Relevant literature on the impact of meteorology on the occurrence and resulting casualties of road traffic injuries was searched. Meta-analysis was performed on the included literature using state16.0 software. Results A total of 28 articles were included. The results of meta-analysis showed that heat wave, cloudy day, snowy day, rainy day and other severe weather such as storm had a statistically significant impact on the occurrence of road traffic injuries. Severe weather such as storms had a statistically significant impact on RTIs casualties. Conclusion Heat wave, cloudy day, snowy day, rainy day, storm and other bad weather are independent risk factors for the occurrence of RTIs. Storm is a risk factor for accident casualties. There is not enough evidence to show that low temperature, cold wave and heavy fog are the influencing factors of road traffic accidents.

A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.

Robustness assessment of cardiovascular meta-analysis / 中国胸心血管外科临床杂志

@#Objective     To evaluate the robustness of cardiovascular meta-analysis with use of fragility index. Methods     By searching PubMed, EMbase, and Web of Science databases from 2018 to 2022, relevant literature on cardiovascular meta-analysis was systematically collected and the fragility indexes were calculated; Spearman correlation analysis was used to explore the relationship between fragility index and sample size, total number of events, effect size and its confidence interval width. Results     A total of 212 meta-analyses from 29 articles were included, with a median fragility index of 11 (5, 25), a median sample size of 10 301 (3 384, 48 330), and a median total number of events of 360 (129, 1 309). Most meta-analyses chose relative risk as the effect measure (179/212), and chose Mantel-Haenszel method (102/212) and random effects model (153/212). The fragility index was positively correlated with the sample size (rs=0.56, P<0.05) and the total number of events (rs=0.61, P<0.05), and negatively correlated with confidence interval width of the effect size (rs=−0.52, P<0.05). No statistically significant results were obtained in the correlation between the fragility index and effect size. Conclusion     The fragility indexes of cardiovascular meta-analyses published in comprehensive journals of high impact factors and professional cardiovascular journals are generally low, and therefore lack robustness. Fragility index is suggested to be reported in medical researches, assisting in explaining the P-value.

ObjectiveTo evaluate the effect of transcranial direct current stimulation (tDCS) on the cognitive function and quality of life in patients with Parkinson's disease. MethodsRandomized controlled trials (RCTs) on tDCS for Parkinson's disease were searched in PubMed, Web of Science, Embase, Cochrane Library, CNKI, CBM, VIP and Wanfang Data from the inception to September, 2023. Control group was administered standard Parkinson's medications or placebo, physical therapy, and cognitive rehabilitation, while treatment group received tDCS additionally. The quality of the researches was evaluated using the Cochrane Risk of Bias Tool. Data synthesis and analysis were performed using RevMan 5.4 and Stata 17.0, with heterogeneity and sensitivity analyses. ResultsEight articles were included. tDCS significantly improved the scores of Montreal Cognitive Assessment (MD = 2.00, 95%CI 1.13 to 2.87, P < 0.001). However, there was no significant difference in the scores of Parkinson's Disease Questionnaire (MD = 0.73, 95%CI -5.78 to 7.23, P = 0.830), Beck Depression Inventory-Ⅱ(MD = -0.77, 95%CI -7.14 to 5.60, P = 0.810), and Unified Parkinson Disease Rating Scale-Ⅲ (MD = 1.60, 95%CI -0.77 to 3.97, P = 0.190). ConclusiontDCS may improve cognitive function of patients with Parkinson's disease.
