Comprehensive effects of traditional Chinese medicine treatment on heart failure and changes in B-type natriuretic peptide levels: A meta-analysis

BACKGROUND Heart failure(HF),a common cardiovascular condition,is characterized by significant morbidity and mortality.While traditional Chinese medicine(TCM)is often used as a complementary approach in HF management,systematic evalua-tions of its impact on clinical outcomes,TCM syndrome scores,and B-type natriuretic peptide(BNP)levels are lacking.This study fills this gap through a comprehensive analysis of randomized controlled trials(RCTs)focusing on TCM for HF treatment.It encompasses an assessment of methodological quality,a meta-analysis,and an evaluation of evidence quality based on established standards.The results offer crucial insights into the potential advantages and constraints of TCM in HF management.RCTs on TCM for HF treatment published since the establishment of the database were searched in four Chinese and English databases,including China National Knowledge Infrastructure,Wanfang,VIP Information Chinese Science and Technology Journal,and PubMed.Methodological quality was assessed for the included studies with the Cochrane risk-of-bias assessment tool,and the meta-analysis and publication bias assessment was performed with the RevMan5.3 software.Finally,the quality of evidence was rated according to the GRADE criteria.RESULTS A total of 1098 RCTs were initially retrieved.After screening,16 RCTs were finally included in our study,which were published between 2020 and 2023.These RCTs involved 1660 HF patients,including 832 in the TCM group[TCM combined with conventional Western medicine(CMW)treatment]and 828 in the CWM group(CWM treatment).The course of treatments varied from 1 wk to 3 months.TCM syndrome differentiation was analyzed in 11 of the included RCTs.In all included RCTs,outcome indicators included comprehensive clinical outcomes,TCM syndrome scores,and BNP levels.The meta-analysis results showed significant differences between the TCM and CWM groups in terms of comprehensive clinical outcomes[risk ratio=-0.54;95%confidence interval(CI)=-0.61,-0.47;P<0.00001],TCM syndrome scores[weighted mean difference(WMD)=-142.07;95%CI=-147.56,-136.57;P<0.00001],and BNP levels(WMD=-142.07;95%CI=-147.56,-136.57;P<0.00001).According to the GRADE criteria,RCTs where"TCM improves clinical comprehensive outcomes"were rated as low-quality evidence,and RCTs where"TCM reduces TCM syndrome scores"or"TCM decreases BNP levels"were rated as medium-quality evidence.CONCLUSION TCM combined with CWM treatment effectively improves comprehensive clinical outcomes and diminishes TCM syndrome scores and BNP levels in HF patients.Given the low and medium quality of the included RCTs,the application of these results should be cautious.

Sequential organ failure assessment score is superior to other prognostic indices in acute pancreatitis

BACKGROUND Acute pancreatitis(AP)is a common surgical condition,with severe AP(SAP)potentially lethal.Many prognostic indices,including;acute physiology and chronic health evaluation II score(APACHE II),bedside index of severity in acute pancreatitis(BISAP),Glasgow score,harmless acute pancreatitis score(HAPS),Ranson’s score,and sequential organ failure assessment(SOFA)evaluate AP severity and predict mortality.AIM To evaluate these indices'utility in predicting severity,intensive care unit(ICU)admission,and mortality.METHODS A retrospective analysis of 653 patients with AP from July 2009 to September 2016 was performed.The demographic,clinical profile,and patient outcomes were collected.SAP was defined as per the revised Atlanta classification.Values for APACHE II score,BISAP,HAPS,and SOFA within 24 h of admission were retrospectively obtained based on laboratory results and patient evaluation recorded on a secure hospital-based online electronic platform.Data with<10%missing data was imputed via mean substitution.Other patient information such as demographics,disease etiology,and patient outcomes were also derived from electronic medical records.RESULTS The mean age was 58.7±17.5 years,with 58.7%males.Gallstones(n=404,61.9%),alcohol(n=38,5.8%),and hypertriglyceridemia(n=19,2.9%)were more common aetiologies.81(12.4%)patients developed SAP,20(3.1%)required ICU admission,and 12(1.8%)deaths were attributed to SAP.Ranson’s score and APACHE-II demonstrated the highest sensitivity in predicting SAP(92.6%,80.2%respectively),ICU admission(100%),and mortality(100%).While SOFA and BISAP demonstrated lowest sensitivity in predicting SAP(13.6%,24.7%respectively),ICU admission(40.0%,25.0%respectively)and mortality(50.0%,25.5%respectively).However,SOFA demonstrated the highest specificity in predicting SAP(99.7%),ICU admission(99.2%),and mortality(98.9%).SOFA demonstrated the highest positive predictive value,positive likelihood ratio,diagnostic odds ratio,and overall accuracy in predicting SAP,ICU admission,and mortality.SOFA and Ranson’s score demonstrated the highest area under receiver-operator curves at 48 h in predicting SAP(0.966,0.857 respectively),ICU admission(0.943,0.946 respectively),and mortality(0.968,0.917 respectively).CONCLUSION The SOFA and 48-h Ranson’s scores accurately predict severity,ICU admission,and mortality in AP,with more favorable statistics for the SOFA score.

Short-term efficacy of robotic and laparoscopic spleen-preserving splenic hilar lymphadenectomy via Huang’s three-step maneuver for advanced upper gastric cancer: Results from a propensity scorematched study

BACKGROUND Robotic surgery has been considered to be significantly better than laparoscopic surgery for complicated procedures.AIM To explore the short-term effect of robotic and laparoscopic spleen-preserving splenic hilar lymphadenectomy(SPSHL)for advanced gastric cancer(GC)by Huang’s three-step maneuver.METHODS A total of 643 patients who underwent SPSHL were recruited from April 2012 to July 2017,including 35 patients who underwent robotic SPSHL(RSPSHL)and 608 who underwent laparoscopic SPSHL(LSPSHL).One-to-four propensity score matching was used to analyze the differences in clinical data between patients who underwent robotic SPSHL and those who underwent laparoscopic SPSHL.RESULTS In all,175 patients were matched,including 35 patients who underwent RSPSHL and 140 who underwent LSPSHL.After matching,there were no significant differences detected in the baseline characteristics between the two groups.Significant differences in total operative time,estimated blood loss(EBL),splenic hilar blood loss(SHBL),splenic hilar dissection time(SHDT),and splenic trunk dissection time were evident between these groups(P<0.05).Furthermore,no significant differences were observed between the two groups in the overall noncompliance rate of lymph node(LN)dissection(62.9%vs 60%,P=0.757),number of retrieved No.10 LNs(3.1±1.4 vs 3.3±2.5,P=0.650),total number of examined LNs(37.8±13.1 vs 40.6±13.6,P=0.274),and postoperative complications(14.3%vs 17.9%,P=0.616).A stratified analysis that divided the patients receiving RSPSHL into an early group(EG)and a late group(LG)revealed that the LG experienced obvious improvements in SHDT and length of stay compared with the EG(P<0.05).Logistic regression showed that robotic surgery was a significantly protective factor against both SHBL and SHDT(P<0.05).CONCLUSION RSPSHL is safe and feasible,especially after overcoming the early learning curve,as this procedure results in a radical curative effect equivalent to that of LSPSHL.

Short-term and long-term outcomes of laparoscopic vs open ileocolic resection in patients with Crohn's disease: Propensityscore matching analysis

BACKGROUND Laparoscopic ileocolic resection(LICR)is the preferred surgical approach for primary ileocolic Crohn’s disease(CD)because it has greater recovery benefits than open ICR(OICR).AIM To compare short-and long-term outcomes in patients who underwent LICR and OICR.METHODS Patients who underwent ICR for primary CD from 2006 to 2017 at a single tertiary center specializing in CD were included.Patients who underwent LICR and OICR were subjected to propensity-score matching analysis.Patients were propensityscore matched 1:1 by factors potentially associated with 30-d perioperative morbidity.These included demographic characteristics and disease-and treatment-related variables.Factors were compared using univariate and multivariate analyses.Long-term surgical recurrence-free survival(SRFS)in the two groups was determined by the Kaplan-Meier method and compared by the log-rank test.RESULTS During the study period,348 patients underwent ICR,211 by the open approach and 137 laparoscopically.Propensity-score matching yielded 102 pairs of patients.The rate of postoperative complication was significantly lower(14%versus 32%,P=0.003),postoperative hospital stay significantly shorter(8 d versus 13 d,P=0.003),and postoperative pain on day 7 significantly lower(1.4 versus 2.3,P<0.001)in propensity-score matched patients who underwent LICR than in those who underwent OICR.Multivariate analysis showed that postoperative complications were significantly associated with preoperative treatment with biologics[odds ratio(OR):3.14,P=0.01]and an open approach to surgery(OR:2.86,P=0.005).The 5-and 10-year SRFS rates in the matched pairs were 92.9%and 83.3%,respectively,with SRFS rates not differing significantly between the OICR and LICR groups.The performance of additional procedures was an independent risk factor for surgical recurrence[hazard ratio(HR):3.28,P=0.02].CONCLUSION LICR yielded better short-term outcomes and postoperative recovery than OICR,with no differences in long-term outcomes.LICR may provide greater benefits in selected patients with primary CD.

Multi-locus genetic risk score predicts risk for Crohn's disease in Slovenian population

AIM: To develop a risk model for Crohn's disease(CD) based on homogeneous population.METHODS: In our study were included 160 CD patients and 209 healthy individuals from Slovenia. The association study was performed for 112 single nucleotide polymorphisms(SNPs). We generated genetic risk scores(GRS) based on the number of risk alleles using weighted additive model. Discriminatory accuracy was measured by area under ROC curve(AUC). For risk evaluation, we divided individuals according to positive and negative likelihood ratios(LR) of a test, with LR > 5 for high risk group and LR < 0.20 for low risk group.RESULTS: The highest accuracy, AUC of 0.78 was achieved with GRS combining 33 SNPs with optimal sensitivity and specificity of 75.0% and 72.7%, respectively. Individuals with the highest risk(GRS >5.54) showed significantly increased odds of developing CD(OR = 26.65, 95%CI: 11.25-63.15) compared to the individuals with the lowest risk(GRS < 4.57) which is a considerably greater risk captured than in one SNP with the highest effect size(OR = 3.24). When more than 33 SNPs were included in GRS, discriminatory ability was not improved significantly; AUC of all 74 SNPs was 0.76.CONCLUSION: The authors proved the possibility of building accurate genetic risk score based on 33 risk variants on Slovenian CD patients which may serve as a screening tool in the targeted population.

Midnight Salivary Cortisol and Other Effective Factors in the Graduation of Clinical Suspect of Cushing Syndrome: Is There Any Reasonable Clinical Score?

Background: Diagnosis of Cushing’s Syndrome (CS) at the right time and with the right method is getting more important for the patients and clinicians due to high mortality rate. The most appropriate laboratory test will provide great benefits in terms of cost-effectiveness in the well-chosen group of patients. Selection of the high risk group is of crucial importance for the true diagnosis and treatment on time. Aim: The aim of this study was to evaluate the worth of the midnight salivary cortisol and to establish other effective factors in the graduation of clinical suspect of CS. Material and Methods: 115 patients were evaluated in weight, height, body mass index (BMI), waist/hip ratio, systolic, diastolic blood pressures, hirsutism, weight gain, purple-stria, plethore, buffalo-hump, supraclavicular fullness, temporal fat cushion, acnea, moonface, proximal muscle weakness, lower limb edema, ecchymosis, loss of libido, depression, diabetes mellitus, hypertension, allopecia of all patients were noted in the evaluation forms (23 findings). Patients were grouped according to clinical scores, low (16). Results: When we compare the groups in terms of midnight salivary cortisol, morning salivary cortisol after overnight dexamethasone suppression test, we found statistically significant relationship between the low and high clinical score groups, as well as between medium and high score groups (p: 0.0001). Urinary free cortisol was statistically significant only between low and high clinical score groups (p: 0.0001). Conclusion: This clinical scoring system which includes clinical signs and laboratory findings both, can be used for selection of the high risk group.

Nutech functional score: A novel scoring system to assess spinal cord injury patients

AIM To develop a new scoring system, nutech functional scores(NFS) for assessing the patients with spinal cord injury(SCI).METHODS The conventional scale, American Spinal Injury Association's(ASIA) impairment scale is a measure which precisely describes the severity of the SCI.However, it has various limitations which lead to incomplete assessment of SCI patients.We have developed a 63 point scoring system, i.e., NFS for patients suffering with SCI.A list of symptoms either common or rare that were found to be associated with SCI was recorded for each patient.On the basis of these lists, we have developed NFS.RESULTS These lists served as a base to prepare NFS, a 63 point positional(each symptom is sub-graded and get points based on position) and directional(moves in direction BAD → GOOD) scoring system.For non-progressive diseases, 1, 2, 3, 4, 5 denote worst, bad, moderate, good and best(normal), respectively.NFS for SCI has been divided into different groups based on the affected part of the body being assessed, i.e., motor assessment(shoulders, elbow, wrist, fingers-grasp, fingers-release, hip, knee, ankle and toe), sensory assessment, autonomic assessment, bed sore assessment and general assessment.As probability based studies required a range of(-1, 1) or at least the range of(0, 1) to be useful for real world analysis, the grades were converted to respective numeric values.CONCLUSION NFS can be considered as a unique tool to assess the improvement in patients with SCI as it overcomes the limitations of ASIA impairment scale.

Assessing gestational age of babies: Performance of obstetric ultrasound scan compared to that from the combination of Naegle’s rule and Dubowitz score in the 21st century

Background: Some researchers have suggested that when Naegle’s rule (NR) and Dubowitz score (DS) are combined, it could out-perform obstetric ultrasound scan (USS). Others still believe that obstetric USS alone is still effective relative to the combination of NR rule and DS in assessing the gestational age (GA) of babies. Objectives: To determine and compare the GA of babies using obstetric USS, NR and DS;and to provide relevant public health information on obstetric USS in the 21st century. Methods: Subjects were selected using systematic random sampling and the GA of babies was determined using obstetric USS, NR, and DS. Statistical package for social science (SPSS) statistical software version 16, Illinois, Chicago USA was used for all data analysis. Results: Eightyfive mother-baby pairs were studied. Forty-four babies (52%) were males and 41 (48%) females. Sixty four (75%) were term with a mean (SD) BW of 3.02 (0.59) at 95%CI (2.89 -?3.14) kg. The overall mean GA of the babies was 38.49 (2.89) at 95%CI (38.14 -?38.85) weeks. The mean GA using obstetric USS, NR and DS were 38.52 (1.98) at 95%CI (38.14 -?38.99), 38.09 (4.13) at 95%CI (37.20-?38.99) and 38.82 (2.02) at 95%CI (38.39 -?39.26), but comparison of these means was not significant (p = 0.256). Combined mean GA by NR and DS was 38.46 (3.26) at 95%CI (37.96 -?38.95). Comparing this mean with mean GA obtained by obstetric USS was also not significant (p = 0.885). Conclusion: The GA assessments by Obstetric USS, NR and DS were all reliable, and Obstetric USS performed effectively relative to combined NR and DS.

Impact of cognition-related single nucleotide polymorphisms on brain imaging phenotype in Parkinson’s disease

Multiple single nucleotide polymorphisms may contribute to cognitive decline in Parkinson’s disease. However, the mechanism by which these single nucleotide polymorphisms modify brain imaging phenotype remains unclear. The aim of this study was to investigate the potential effects of multiple single nucleotide polymorphisms on brain imaging phenotype in Parkinson’s disease. Forty-eight Parkinson’s disease patients and 39 matched healthy controls underwent genotyping and 7 T magnetic resonance imaging. A cognitive-weighted polygenic risk score model was designed, in which the effect sizes were determined individually for 36 single nucleotide polymorphisms. The correlations between polygenic risk score, neuroimaging features, and clinical data were analyzed. Furthermore, individual single nucleotide polymorphism analysis was performed to explore the main effects of genotypes and their interactive effects with Parkinson’s disease diagnosis. We found that, in Parkinson’s disease, the polygenic risk score was correlated with the neural activity of the hippocampus, parahippocampus, and fusiform gyrus, and with hippocampal-prefrontal and fusiform-temporal connectivity, as well as with gray matter alterations in the orbitofrontal cortex. In addition, we found that single nucleotide polymorphisms in α-synuclein(SNCA) were associated with white matter microstructural changes in the superior corona radiata, corpus callosum, and external capsule. A single nucleotide polymorphism in catechol-O-methyltransferase was associated with the neural activities of the lingual, fusiform, and occipital gyri, which are involved in visual cognitive dysfunction. Furthermore, DRD3 was associated with frontal and temporal lobe function and structure. In conclusion, imaging genetics is useful for providing a better understanding of the genetic pathways involved in the pathophysiologic processes underlying Parkinson’s disease. This study provides evidence of an association between genetic factors, cognitive functions, and multi-modality neuroimaging biomarkers in Parkinson’s disease.

IFIH1 and DDX58 gene variants in pediatric rheumatic diseases

BACKGROUND The IFIH1 gene codes the MDA5 protein and the DDX58 gene codes the RIG-I receptor.Both proteins are parts of the interferon(IFN)I signaling pathway and are responsible for antiviral defense and innate immune response.IFIH1 and DDX58 polymorphisms are associated with a spectrum of autoimmune diseases.Rare gain-of-function IFIH1 mutations have been found in Singleton-Merten and Aicardi-Goutières syndrome,while DDX58 mutation can cause atypical Singleton-Merten syndrome.AIM To characterize children with pediatric rheumatic diseases(PRD)carrying DDX58 or IFIH1 variants.METHODS Clinical exome sequencing was performed on 92 children with different PRD.IFIH1 and DDX58 variants have been detected in 14 children.IFN-I score has been analyzed and the clinical characteristics of patients have been studied.RESULTS A total of seven patients with systemic lupus erythematosus(SLE)(n=2),myelodysplastic syndrome with SLE features at the onset of the disease(n=1),mixed connective tissue disease(MCTD)(n=1),undifferentiated systemic autoinflammatory disease(uSAID)(n=3)have 5 different variants of the DDX58 gene.A common non-pathogenic variant p.D580E has been found in five children.A rare variant of uncertain significance(VUS)p.N354S was found in one patient with uSAID,a rare likely non-pathogenic variant p.E37K in one patient with uSAID,and a rare likely pathogenic variant p.Cys864fs in a patient with SLE.Elevated IFN-I score was detected in 6 of 7 patients with DDX58 variants.Seven patients had six different IFIH1 variants.They were presented with uSAID(n=2),juvenile dermatomyositis(JDM)(n=1),SLElike disease(n=1),Periodic fever with aphthous stomatitis,pharyngitis,and adenitis syndrome(n=1),and systemic onset juvenile idiopathic arthritis(n=1).Three patients have VUS p.E627X,one patient has benign variant p.I923V.Rare VUS p.R595H was detected in the JDM patient.Another rare VUS p.L679Ifs*2 and previously not reported variant p.V599Ffs*5 were detected in the patient with uSAID.One patient with uSAID has rare VUS p.T520A.All patients had elevated IFN-I scores.CONCLUSION Rare compound-heterozygous IFIH1 variant(p.L679Ifs*2 and p.V599Ffs*5),heterozygous IFIH1 variant(p.T520A)and heterozygous DDX58 variant(p.Cys864fs)are probably disease causative for uSAID and SLE.The majority of patients with different DDX58 and IFI1 variants had hyperactivation of the IFN I signaling pathway.

目的研究Aspect和HXD脑电双频指数监测仪 (BIS)与麻醉镇静程度的相关性以及两者的差异性。方法根据麻醉分级术前评估标准ASA ,10例Ⅰ～Ⅱ级女性行普外或妇科手术病人 ,于同一病人同时连接两台BIS仪 ,分为H组和A组 ,以警觉 /镇静 (OAA/S)作为镇静评分 ,记录麻醉诱导及苏醒过程中BIS的变化值 ,并记录其血压(MAP)、心率 (HR)。麻醉诱导和维持异丙酚采用靶控输注技术 (TCI) ,调整异丙酚的靶浓度 ,使BIS值维持在 4 0～ 6 0之间。分析麻醉诱导和苏醒期OAA/S分别为 5、4、3、2时两组的BIS值、MAP、HR值。 结果两组的BIS与OAA/S的相关性均接近于 1(P <0 .0 1)。配对t检验无显著性差异 (P >0 .0 5 )。MAP和HR与OAA/S无相关性 (P >0 .0 5 )。 结论Aspect和HXD都能很好地反映麻醉的镇静程度 ,而且HXD的性能与Aspect相似 。
