Objective To systematically evaluate the difference in leg length discrepancy (LLD) between robot-assisted total hip arthroplasty (THA) and traditional THA. Methods The Cochrane Library, PubMed, Web of Science, EMbase, CNKI, Wanfang, VIP, and CBM databases were searched by computer to collect cohort studies of robot-assisted and traditional THAs from inception to August 11th, 2021. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias of the included studies. Meta-analysis was performed using RevMan 5.3 software. ResultsA total of 10 high-quality cohort studies were included. The results of Meta-analysis showed that compared with traditional THA, LLD after robot-assisted THA was smaller [MD=?1.64, 95%CI (?2.25, ?1.04), P<0.001], Harris scores at 3 and 12 months after operation were higher [MD=1.50, 95%CI (0.44, 2.57), P=0.006; MD=7.60, 95%CI (2.51, 12.68), P=0.003]. However, the operative time was longer [MD=8.36, 95%CI (4.56, 12.17), P<0.000 1], and the postoperative acetabular anteversion angle was larger [MD=1.91, 95%CI (1.43, 2.40), P<0.001]. There was no significant difference in Harris score at 6 months, amnesia index (Forgotten joint score, FJS), postoperative acetabular abduction angle, and incidence of complication between the two groups (P>0.05). Conclusion Robot-assisted THA is superior to traditional THA in postoperative LLD.
ObjectiveTo summarize the clinical experience of the uniportal thoracoscopic anatomical sub-segmentectomy of the basal segment. MethodsThe clinical data of 34 patients who underwent uniportal thoracoscopic anatomical sub-segmentectomy of the basal segment in our department between April 2018 and April 2021 were retrospectively analyzed. There were 19 males and 15 females with a median age of 56.5 (28.0-76.0) years, a 3-4 cm incision was made in the 5th intercostal area at the front axillary line, and anatomical sub-segmentectomy of the basal segment was performed. Results The surgery was successfully performed in all patients, and there was no patient with additional chest incision or transfer to thoracotomy. The median operation time was 165.0 (125.0-220.0) min, intraoperative blood loss was 120.0 (70.0-290.0) mL, thoracic drainage time was 3.5 (2.0-24.0) d, and hospitalization time was 6.0 (3.0-26.0) d. There was no death during the hospitalization. Postoperative complications included 4 patients of atrial fibrillation, 2 patients of blood sputum, 3 patients of persistent air leakage, and they were recovered after conservative treatment. One patient developed pneumothorax after discharge, 1 patient developed pleural effusion, and both of them recovered after drainage. Postoperative pathology showed microinvasive adenocarcinoma in 22 patients, adenocarcinoma in situ in 7 patients, benign tumors in 5 patients. The lymph nodes were negative in all patients. Conclusion The uniportal thoracoscopic anatomical sub-segmentectomy of the basal segment is safe and feasible, and can be popularized and applied in clinic.
Objective To explore the association between cough patterns and cerebrovascular disease risk, and to provide epidemiological evidence for the early diagnosis and prevention of cerebrovascular disease. Methods During the period from 2010 to 2012 in Guizhou Province, a multi-stage proportional stratified cluster sampling method was used to recruit people with the inclusion criteria of the study into a cohort and a baseline questionnaire for demographic information, lifestyle, and disease history was administered. The incidence of cerebrovascular disease was followed up from 2016 to 2020. Results A total of 4804 subjects were followed up, and 4589 (53.5% were female) subjects were enrolled in final investigation. Compared with non-chronic cough group, there was no statistical significance in the risk of cerebrovascular diseases (P>0.05), however, chronic cough (the risk ratio was 2.00 and the 95% confidence interval ranged from 1.08 to 3.69) was twice as likely to develop cerebrovascular disease as non-cough. Conclusions People with chronic cough are more likely to develop cerebrovascular disease than people without cough. More attention to the management and control of cough should be paid to avoid chronic cough, so as to reduce the risk of cerebrovascular diseases.
ObjectiveTo investigate the clinical effect of metal supported multi-sided versus ordinary ultra-fine drainage tube in the uniportal video-assisted thoracic surgery (VATS) lower pulmonary lobectomy. MethodsFrom January 2021 to June 2022, the clinical data of patients who underwent uniportal VATS lower lobectomy in our hospital were retrospectively analyzed. According to the different types of ultra-fine drainage tubes used in the surgery, the patients were divided into an experimental group (using multi-sided hole 10F ultra-fine drainage tubes with metal support) and a control group (using ordinary 12F ultra-fine drainage tubes). The clinical data of the two groups were compared. ResultsA total of 190 patients were enrolled, including 108 males and 82 females. There were 90 patients in the experimental group aged 56.60±10.14 years; and 100 patients in the control group aged 57.07±11.04 years. The incidences of postoperative lung infection and pleural effusion in the experimental group were lower than those in the control group, with statistically significant differences (P<0.05). The postoperative visual analogue scale score, the need to adjust the chest drainage tube after the surgery, the need for chest puncture after the surgery, the time of postoperative chest tube removal, and the hospitalization cost were statistically different (P<0.05). There was no statistical difference in the length of postoperative hospital stay or the incidences of postoperative lung leakage, arrhythmia, and atelectasis complications (P>0.05). ConclusionCompared with the ordinary ultra-fine drainage tubes, multi-sided hole ultra-fine drainage tubes with metal support can reduce the incidences of lung infection and pleural effusion complications after the uniportal VATS lower lobectomy, reduce the pain and economic burden, which can be applied in the uniportal VATS lower lobectomy.
Objective
To explore the association between 25-hydroxyvitamin D (25OHD) level and risk of the onset of metabolic syndrome (MS) in people in Chengdu.
Methods
In total, 474 participants were selected randomly by cluster sampling from one urban district and two rural villages in Longquanyi district of Chengdu. The data of sociodemographic information, lifestyle and family history were collected by questionnaires. Binary logistic regression was performed to assess the relationship between baseline 25OHD level and incident of MS, while multiple linear regression was conducted to analyze the relationship between baseline 25OHD level and insulin resistance.
Results
Four hundred seventy-four people were enrolled in the cohort study, 39 of them developed MS, with the incidences of 20.8 events per 1 000 person years. Among women, low 25OHD status was significantly associated with the risk of developing MS (OR=4.29, 95%CI 1.05 to 29.50, P=0.044) after adjustment for multiple potential confounders. In a multiple linear regression analysis, low 25OHD level of baseline was independently associated with the increased HOMA-IR over a 4-year period among Chengdu individuals (P<0.05) and was independently related to the decreased ISIcomp over a 4-year period in female (P<0.05).
Conclusions
The current prospective study suggests that low 25OHD level may contribute to increase insulin resistance in Chengdu population. Furthermore, low 25OHD level may increase the risk of MS among women in Chengdu.
Objective To compare the clinical efficacy and safety of da Vinci robot with totally no tube (TNT) versus subxiphoid video-assisted thymectomy surgery (SVATS) in the treatment of thymic tumors. Methods From 2019 to 2021, a retrospective analysis was conducted on patients with thymic tumor resection in the Department of Thoracic Surgery, General Hospital of Northern Theater Command. All patients underwent total thymectomy and mediastinal fat removal, and they were divided into a TNT group and a SVATS group according to the operation method. The intraoperative blood loss, conversion rate, postoperative visual analogue score (VAS), postoperative hospital stay time and postoperative complications were compared between the two groups. Results We finally included 435 patiets. There were 168 patients with 83 males and 85 females at an average age of 61.920±9.210 years in the TNT group and 267 patients with 147 males and 120 females at an average age of 61.460±8.119 years in the SVATS group. There was no death or postoperative myasthenic crisis in both groups. There was no statistical difference in postoperative hospital stay (1.540±0.500 d vs. 3.400±0.561 d, P=0.000), intraoperative blood loss (13.450±5.498 mL vs. 108.610±54.462 mL, P=0.000), postoperative 24 h VAS score (4.960±1.757 points vs. 3.600±1.708 points, P=0.000), or postoperative complication rate (3.0% vs. 11.6%, P=0.001).Conclusion TNT is a more efficient, safe, and effective surgical approach for treating thymic tumors, which can shorten hospital stay time and reduce postoperative complications. However, SVATS can minimize postoperative pain.
Objective To investigate the relationship between miR-3187-5p in peripheral blood and pericardial drainage after coronary artery bypass grafting (CABG) and postoperative atrial fibrillation (POAF). Methods Patients who underwent CABG in the Heart Center of Beijing Chao-Yang Hospital from March to May 2022 were enrolled. Peripheral blood and pericardial drainage were collected at 0 h after surgery (immediate time for patients to return to ICU from operating room) to detect miR-3187-5p, and perioperative confounding factors were also collected. The miR-3187-5p was measured by quantitative real-time PCR and its regulated target genes were analyzed by bioinformatics. Results A total of 15 patients were enrolled, including 9 males and 6 females with an average age of 65.6±8.2 years. The incidence rate of POAF was 40.0%. miR-3187-5p in pericardial drainage at 0 h after surgery was an independent predictor for POAF. A total of 1 642 target genes of miR-3187-5p were predicted. GO function enrichment analysis and KEGG signal pathway enrichment analysis showed that target genes of miR-3187-5p were enriched in TGF-β, MAPK, Wnt and other classical collagen metabolic signal pathways, which might activate collagen metabolism by negatively regulating SMAD6 and other inhibitors of the pathways. Conclusion This study is the first to find that miR-3187-5p in pericardial drainage at 0 h after surgery is a potential, novel, and predictive factor for POAF, which may be related to the regulation of myocardial fibrosis signal pathways like TGF-β, MAPK and Wnt pathways, promoting the early collagen metabolism imbalance after CABG, increasing the collagen deposition in the atrium, and then promoting the early structural reconstruction after CABG and leading to the occurrence of POAF. The result provides a research basis for the accurate prediction and prevention of clinical POAF.
Objectives
To investigate the correlation between blood total cholesterol (TC) and prognosis of idiopathic sudden sensorineural hearing loss (ISSNHL) and to provide references for clinical treatment and prognosis assessment.
Methods
We included 232 ISSNHL patients with total deafness in Wenzhou Central Hospital from June 2015 to March 2017 using a prospective cohort design. Recording information including age, gender, hypertension, diabetes mellitus, vertigo, level of blood total cholesterol (TC), level of triglyceride (TG), level of low-density lipoprotein (LDL-C) and LDL/HDL ratio (LDL-C/HDL-C) were collected. Correlation between the prognosis of ISSNHL and blood total cholesterol were analyzed by univariable and multivariable logistic regression analysis.
Results
The clinical effective rate of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L was higher than that of patients with TC lower than 5.2 mmol/L (univariable: RR=6.49, 95%CI 3.16 to 13.30, P<0.001; multivariable-adjusted covariates: RR=6.15, 95%CI 2.66 to 14.3,P<0.001) with significant difference. No significant difference was found between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (univariable: RR=1.02, 95%CI 0.52 to 2.00,P=0.960; multivariable-adjusted covariates: RR=1.61, 95%CI 0.55 to 4.73, P=0.386). Gender-specific analysis showed for both male and female groups, the effective rates of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L were significantly higher than those of patients with TC lower than 5.2 mmol/L. There was no significant difference between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (P>0.05) in either male group or female group.
Conclusion
The current study suggests that patients with levels of TC ranging from 5.2 mmol/L to 6.2 mmol/L predicts the best prognosis.
ObjectiveTo investigate the changes of fibrinogen and classical markers of collagen metabolism [carboxy-terminal propeptide of type Ⅰ procollagen (PICP) and carboxy-terminal cross-linked peptide of type Ⅰ collagen (ICTP)] in peripheral blood and pericardial drainage after coronary artery bypass grafting (CABG) and/or heart valve replacement (VR), and to evaluate their relationship with postoperative atrial fibrillation (POAF) after cardiac surgery. MethodsPatients who underwent CABG and/or VR in the Heart Center of Beijing Chao-Yang Hospital from March to June 2021 were included. Peripheral blood and pericardial drainage fluid samples were collected before surgery and at 0 h, 6 h, 24 h and 48 h after surgery to detect PICP, ICTP and fibrinogen levels, and preoperative, intraoperative and postoperative confounding factors were also collected. PICP, ICTP and fibrinogen levels were measured by enzyme-linked immunosorbent assay (ELISA). ResultsA total of 26 patients with 125 blood samples and 78 drainage samples were collected. There were 18 males and 8 females with an average age of 64.04±7.27 years. The incidence rate of POAF was 34.6%. Among the factors, the fibrinogen level in pericardial drainage showed two peaks within 48 h after operation (0 hand 24 h after operation) in the POAF group, while it showed a continuous downward trend in the sinus rhythm (SR) group, and the change trend of fibrinogen in pericardial drainage was significantly different over time between the two groups (P=0.022). Fibrinogen in blood, PICP and ICTP in blood and drainage showed an overall decreasing trend, and their trends over time were not significantly different between the two groups of patients (P>0.05). Univariate analysis showed that fibrinogen at 24 h and 48 h after pericardial drainage, fibrinogen in preoperative blood, PICP immediately after surgery and right atrial long axis diameter were significantly higher or longer in the POAF group than those in the SR group. Multiple regression showed that fibrinogen≥11.47 ng/mL in pericardial drainage 24 h after surgery (OR=14.911, 95%CI 1.371-162.122, P=0.026), right atrial long axis diameter≥46 mm (OR=10.801, 95%CI 1.011-115.391, P=0.049) were independent predictors of POAF. ConclusionThis study finds the regularity of changes in fibrinogen and collagen metabolic markers after CABG and/or VR surgery, and to find that fibrinogen in pericardial drainage 24 h after surgery is a potential novel and predictive factor for POAF. The results provide a new idea for exploring the mechanism of POAF, and provide a research basis for the accurate prediction and prevention of clinical POAF.
ObjectiveTo compare the satisfaction and safety of patients undergoing prepectoral breast reconstruction (PBR) versus subpectoral dual-plane breast reconstruction (SBR) with implants combined with mesh after open total mastectomy for breast cancer. MethodsA prospective cohort study on clinical data of breast cancer patients who underwent open total mastectomy and received either PBR or SBR with implants and mesh for immediate breast reconstruction from June 2021 to October 2022 at West China Hospital of Sichuan University were performed. The pain scores on postoperative days 1, 3, 7, and 14, the postoperative use of analgesics within 14 days, and the incidence of postoperative complications, breast satisfaction, and quality of life during follow-up periods were compared between the two groups. ResultsA total of 62 female patients were included, with 35 in the PBR group, having an average age of (39.6±6.5) years, and 27 in the SBR group, having an average age of (41.5±9.9) years. The pain scores of the SBR group on postoperative days 3 (P=0.032), 7 (P＜0.001), and 14 (P＜0.001) were significantly higher than those of the PBR group, and a higher proportion of patients in the SBR group used analgesics within postopeartive 14 days (P=0.001). The median follow-up time was 28.4 months for the PBR group and 34.9 months for the SBR group. There was no statistical difference in the overall (P=0.583), major (P=0.526), or minor (P=0.532) complication rates between the two groups during follow-up. One (2.9%) patient in the PBR group and 2 (7.4%) patients in the SBR group lost their implants (P=0.575). There were 4 patients of movement deformities and 4 patients of chest muscle pain in the SBR group, whereas no patients in the PBR group had these complications (P=0.031). Encapsular contracture occurred in 5 (14.3%) patients in the PBR group and 11 (40.7%) patients in the SBR group (P=0.023). The incidences of ripple sign (25.7% vs. 3.7%, P=0.047) and implant contour visibility (40.0% vs. 11.1%, P=0.020) were significantly higher in the PBR group than those in the SBR group. At 24 months post-surgery, breast satisfaction scores [(67.9±13.1) points vs. (52.6±16.9) points, P=0.025] and chest function satisfaction [(70.7±13.4) points vs. (58.7±14.3) points, P=0.035] were higher in the PBR group. No local recurrence, distant metastasis, or deaths occurred in the PBR group during the follow-up period, while 1 patient of local recurrence and distant metastasis occurred in the SBR group, with no deaths. ConclusionCompared to SBR, PBR is more in line with the physiological and anatomical levels of the breast, effectively avoiding postoperative movement deformities and chest muscle pain, with a lower incidence of capsular contracture, and higher postoperative breast satisfaction and chest function satisfaction. It is a safe and feasible reconstruction method. For some specific patients, especially those with higher physical activity demands, it is a better reconstruction choice.
