Objective To explore the occurrence condition of the neck axial symptom (AS) after cervical Bryan artificial disc replacement combined with anterior cervical discectomy and fusion (Hybrid surgery) and traditional anterior cervical discectomy and fusion (ACDF surgery) to treat the two-level cervical disease, and to do contrastive analysis. Methods Between August 2006 and March 2010, 18 patients underwent Hybrid surgery (group A) and 30 patients underwent two-level ACDF surgery (group B). There was no significant difference in age, gender, disease duration, type, and operated segment between 2 groups (P gt; 0.05). The Japanese Orthopaedic Association (JOA) score, neck disability index (NDI) score, cervical curvature of the operated segment, total range of motion (ROM) of C2-7, ROM of the adjacent segment, and incidence of neck AS were recorded and compared between before operation and at last follow-up. Results All the patients were followed up 18-34 months (24.1 months on average). In both groups, the JOA and NDI scores at last follow-up had significantly improvement when compared with preoperative scores (P lt; 0.01), but there was no significant difference between 2 groups at preoperation and last follow-up (P gt; 0.05). The kyphosis incidence of the operated segment in group B was significantly higher than that in group A (χ2=5.333, P=0.021). There was no significant difference in the total ROM of C2-7 between at preoperation and last follow-up in group A (t=0.410, P=0.685); the total ROM of C2-7 at last follow-up was significantly lower than that at preoperation in group B (t=3.007, P=0.006); and significant difference was found between 2 groups at last follow-up (t=2.664, P=0.013). At last follow-up, ROM of the superior and inferior adjacent segments in group B increased obviously (P lt; 0.05) and was significantly higher than that in group A (t=2.252, P=0.033; t=2.203, P=0.037). The incidence of neck AS were 16.7% in group A and 46.7% in group B, showing significant difference at last follow-up (χ2=4.427, P=0.035). Conclusion Compared with two-level ACDF surgery, Hybrid surgery has good outcomes. At the same time, it can maintain the curvature of operated segments and total ROM, avoid excessive increased ROM of the adjacent segments, and reduce the incidence of neck AS.
Objective To investigate the influence of preoperative symptom duration on effectiveness of cervical disc arthroplasty (CDA) in cervical spondylotic radiculopathy (CSR) patients. Methods The clinical data of 90 CSR patients who underwent single-segment CDA between January 2008 and March 2020 and met the selection criteria were retrospectively analyzed. Based on preoperative symptom duration, patients were divided into an early intervention group (preoperative symptom duration <24 months) and a late intervention group (preoperative symptom duration ≥24 months). There was no significant difference in baseline data between the two groups (P>0.05), including age, gender, body mass index, smoking status, surgical segment, preoperative neck disability index (NDI), visual analogue scale (VAS) score, cervical lordosis (CL), C2-C7 range of motion (ROM), disc angle (DA), disc ROM (DROM), and disc intervertebral height (DIH). The early intervention group had a slightly higher preoperative Japan Orthopedic Association (JOA) score than the late intervention group (P<0.05). Perioperative indicators such as operation time, intraoperative blood loss, and postoperative hospital stay were recorded. The changes of JOA score, NDI, and VAS score at last follow-up compared with those before operation were used to evaluate the clinical efficacy, and the imaging evaluation of CL, C2-C7 ROM, DA, DROM, and DIH was performed before operation, immediately after operation, and at last follow-up. The incidence of prosthesis-related complications, including heterotopic ossification (HO), anterior bone loss (ABL), and prosthesis subsidence, was also assessed at last follow-up. Results Patients in both groups were followed up 24-120 months, with an average of 53.4 months. There was no significant difference in operation time, intraoperative blood loss, or follow-up duration between the groups (P>0.05). However, the late intervention group had significantly longer postoperative hospital stay compared to the early intervention group (P<0.05). At last follow-up, there was no significant difference in the changes of JOA score, NDI, and VAS score between the two groups before and after operation (P>0.05). During the follow-up, there was no surgical revision in the two groups, and there was no significant difference in the incidence of HO, ABL, and prosthesis subsidence between the two groups at last follow-up (P>0.05). Imaging evaluation showed that there was no significant difference in CL, C2-C7 ROM, DA, DROM, and DIH between the two groups at each time point before and after operation (P>0.05). The intra-group comparison showed that the early intervention group could maintain the immediate postoperative CL at last follow-up, while the late intervention group had recovered to the preoperative level. Additionally, the C2-C7 ROM, DROM, and DA had all recovered to preoperative levels at last follow-up in both groups; meanwhile, the DIH significantly increased immediately after operation and sustained until the last follow-up.ConclusionPreoperative symptom duration significantly affects the effectiveness of CDA in CSR patients. Patients with preoperative symptom duration ≥24 months have longer postoperative hospital stays and potentially poorer ability to maintain CL compared with patients with preoperative symptom duration <24 months.
ObjectiveTo systematically review the efficacy of exercise intervention on smoking cessation. MethodsCNKI, WanFang Data, VIP, Web of Science, PubMed and EMbase databases were electronically searched to collect randomized controlled trials (RCTs) and randomized cross controlled trials (RCDs) on exercise intervention for smoking cessation from inception to September 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Then, meta-analysis was performed using Stata 12.0 software. ResultsA total of 47 studies (35 RCTs and 12 RCDs) involving 5 130 subjects were included. The results of meta-analysis showed that acute exercise could significantly reduce the quitters’ desire to smoke (P<0.05), alleviate most of the withdrawal symptoms, and the effect of acute exercise was maintained for at least 30 minutes. Periodic exercise significantly reduced 7-day point abstinence and sustained abstinence rates in ex-smokers (P<0.05), and the effect of periodic exercise was maintained for at least 12 weeks, however, depression and stress were not found to be effectively relieved, and mood was not found to be significantly improved (P>0.05). ConclusionExercise intervention to quit smoking has a positive effect, however, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo investigate the effect of modified lateral mass screws implantation strategy on axial symptoms in cervical expansive open-door laminoplasty. MethodsA clinical data of 166 patients, who underwent cervical expansive open-door laminoplasty between August 2011 and July 2016 and met the selection criteria, was retrospective analyzed. Among them, 81 patients were admitted before August 2014 using the traditional mini-plate placement and lateral mass screws implantation strategy (control group), and 85 patients were admitted after August 2014 using modified lateral mass screws implantation strategy (modified group). There was no significant difference in the gender composition, age, clinical diagnosis, disease duration, diseased segment, and preoperative Japanese Orthopaedic Association (JOA) score, pain visual analogue scale (VAS) score, Neck Disability Index (NDI), cervical curvature and range of motion, spinal canal diameter and cross-sectional areas, and Pavlov’s value between the two groups (P>0.05). The operation time, intraoperative blood loss, the number of facet joints penetrated by lateral mass screws, effectiveness evaluation indexes (JOA score and improvement rate, VAS score, NDI), imaging evaluation indexes (cervical curvature and range of motion, spinal canal diameter and cross-sectional areas, Pavlov’s value, and lamina open angle), and complications were recorded and compared between the two groups.ResultsThe modified group had shorter operation time and lower intraoperative blood loss than the control group (P<0.05). There were 121 (29.9%, 121/405) and 10 (2.4%, 10/417) facet joints penetrated by lateral mass screws in control and modified groups, respectively; and the difference in incidence was significant (χ2=115.797, P=0.000). Eighteen patients in control group had 3 or more facet joints penetrated while no patients in modified group suffered 3 or more facet joint penetrated. The difference between the two groups was significant (P=0.000). All patients were followed up, the follow-up time was (28.7±4.9) months in modified group and (42.4±10.7) months in control group, showing significant difference (t=10.718, P=0.000). The JOA score, VAS score, and NDI at last follow-up of the two groups were significantly improved compared with preoperative (P<0.05); there was no significant difference in JOA score and improvement rate and VAS score between the two groups (P>0.05), but the NDI was significantly lower in modified group than in control group (P<0.05). There were significant differences in cervical curvature and range of motion, spinal canal diameter, Pavlov’s value, and cross-sectional areas at last follow-up when compared with those before operation in both groups (P<0.05). There was no significant difference in the above indicators and lamina open angle between the two groups (P>0.05). The modified group has a relative lower axial symptom rate (23/85, 27.1%) than the control group (27/81, 33.3%), but the difference was not significant (Z=?1.446, P=0.148). There was no significant differences between the two groups in the incidences of C5 nerve root palsy, cerebrospinal fluid leakage, wound infection, and lung or urinary tract infection (P>0.05). ConclusionIn the cervical expansive open-door laminoplasty, the modified lateral mass screws implantation strategy can effectively reduce the risk of lateral mass screw penetrated to the cervical facet joints, and thus has a positive significance in avoiding the axial symptoms caused by facet joint destruction.
Objective To explore the effect of kidney transplantation on chronic prostatitis-like symptoms. Methods A total of 300 male renal transplant recipients between January 2015 and January 2017 were collected in the study. All recipients received the questionnaire survey of the National Institute of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) preoperatively and at 3 months after transplantation. The score and relevant risk factors were statistically analyzed. Results A total of 210 recipients (70.0%) completed questionnaire effectively, in whom 150 (71.4%) had preoperative and 90 (42.9%) had postoperative chronic prostatitis-like symptoms, respectively. In the 210 patients, the preoperative and postoperative pain score was 6.57±3.12 vs. 3.57±3.16 (P<0.001), voiding score was 3.71±2.38vs. 3.29±2.66 (P=0.116), quality of life score was 7.57±1.60 vs. 5.14±2.75 (P<0.001), and the total NIH-CPSI score was 17.86±3.81vs. 12.00±6.65 (P<0.001), respectively. The severity of chronic prostatitis-like symptoms was alleviated significantly after kidney transplantation. Conclusion Kidney transplantation can alleviate the chronic prostatitis-like symptoms significantly, and improve the quality of life in uremia patients.
ObjectiveTo summarize basic research progress and current status of clinical diagnosis and therapy for gastroesophageal reflux disease. MethodRelated literatures were collected to review the pathogenesis, clinical manifestations, diagnosis and therapy of gastroesophageal reflux disease. ResultsGastroesophageal reflux disease was caused by many factors, such as hiatus hernia, hypotensive lower esophageal sphincter pressure, acid pocket, prolonged esophageal clearance, and delayed gastric emptying. Extra-esophageal symptoms was a common clinical presentation to gastroesophageal reflux disease. The diagnosis methods for gastroesophageal reflux disease included the symptom observation, gastroscopy examination, 24 h pH monitoring of esophageal, proton pump inhibitor test, questionnaire of gastroesophageal reflux disease and so on. The laparoscopic fundoplication could essentially treat the pathophysiologic abnormalities of gastroesophageal reflux disease, which had an obvious curative effect and wide application prospect. ConclusionPathogenesis, diagnosis, and therapy of gastroesophageal reflux disease are associated with multiple factors, which is still controversial and remains to be further studied.
The postoperative symptom burden in patients with lung cancer is severe and adversely impairs their quality of life. Symptom management is the cornerstone of medical care. Patient-reported outcome (PRO)-based symptom management is being increasingly recognized as the best "patient-centered care" model in clinical practice. However, the precise implementation of this model in patients undergoing lung cancer surgery is hindered by the lack of a lung cancer surgery-specific scale, implementation standards, clinical application parameters and high-quality researches. The use of a precise and simple PRO scale and an electronic PRO platform may greatly improve the feasibility of implementing this model. Currently, the application of PRO-based symptom management in lung cancer surgery is still being explored and needs to be improved in clinical research and practice.
Objective To understand the new characteristics of clinical symptoms of patients with mild COVID-19 during the prevalence of SARS-CoV-2 Omicron, and provide basis for better prevention and treatment of COVID-19.Methods A cross-sectional retrospective study was conducted with WeChat questionnaire among medical staff with COVID-19 recently, who come from the Third Affiliated Hospital of Chongqing Medical University and The Second Affiliated Hospital of Army Medical University.Results A total of 630 valid questionnaires was received. 99.2% of infected people had been vaccinated against COVID-19. 2.4% of infected persons developed pneumonia and 2.1% were hospitalized. The most common symptoms after infection were coughing (89.7%), fever (83.0%), fatigue (84.1%), headache and dizziness (75.7%), muscle soreness (72.7%), sore throat (62.1%), nasal congestion and runny nose (60.6%), expectoration (71.6%), anorexia (58.0%) and taste loss (40.2%). The incidence of gastrointestinal symptoms and cardiovascular symptoms was relatively low (17.8% and 31.0% respectively). The severity of self-reported symptoms of most infected persons was moderate or severe. The proportion of serious symptoms reported was coughing (23.8%), sore throat (27.0%), headache and dizziness (17.9%). The severity of symptoms reported by young group (<35 years old) was significantly higher than that of older group (>35 years old). Fever was the highest at 38 to 39 ℃ (52.4%). 77.0% of fever sustained for 1 to 3 days. At the time of investigation, the viral detection turned negative in 60.6% of infected people, and the time of turning negative was mostly 7 to 10 days. More than half of the infected persons still had different symptoms, among which cough (43.7%) and fatigue (23.8%) were the most common.Conclusions Most subjects with mild COVID-19 infection have obvious upper respiratory tract and systemic symptoms, the most prominent is the high incidence of cough, which has become a new feature of omicron infection. And most of the infected people have moderate to severe symptoms, and the younger ones have more severer symptoms.
Long-term chronic internal jugular vein (IJV) insufficiency, originally viewed as a non-pathological finding, may result in cerebral venous outflow disturbance, leading to cerebral venous ischemia and cerebral nervous functional disorders. In this article we discuss probable etiologies, symptoms, diagnosis and treatment of IJV disturbance, so as to provide some insights for clinicians.
ObjectiveTo explore the utility of machine learning-based radiomics models for risk stratification of severe asymptomatic carotid stenosis (ACS). MethodsThe clinical data and head and neck CT angiography images of 188 patients with severe carotid artery stenosis at the Department of Cardiovascular Surgery, China-Japan Friendship Hospital from 2017 to 2021 were retrospectively collected. The patients were randomly divided into a training set (n=131, including 107 males and 24 females aged 68±8 years), and a validation set (n=57, including 50 males and 7 females aged 67±8 years). The volume of interest was manually outlined layer by layer along the edge of the carotid plaque on cross-section. Radiomics features were extracted using the Pyradiomics package of Python software. Intraclass and interclass correlation coefficient analysis, redundancy analysis, and least absolute shrinkage and selection operator regression analysis were used for feature selection. The selected radiomics features were constructed into a predictive model using 6 different supervised machine learning algorithms: logistic regression, decision tree, random forest, support vector machine, naive Bayes, and K nearest neighbor. The diagnostic efficacy of each prediction model was compared using the receiver operating characteristic (ROC) curve and the area under the curve (AUC), which were validated in the validation set. Calibration and clinical usefulness of the prediction model were evaluated using calibration curve and decision curve analysis (DCA). ResultsFour radiomics features were finally selected based on the training set for the construction of a predictive model. Among the 6 machine learning models, the logistic regression model exhibited higher and more stable diagnostic efficacy, with an AUC of 0.872, a sensitivity of 100.0%, and a specificity of 66.2% in the training set; the AUC, sensitivity and specificity in the validation set were 0.867, 83.3% and 78.8%, respectively. The calibration curve and DCA showed that the logistic regression model had good calibration and clinical usefulness. ConclusionThe machine learning-based radiomics model shows application value in the risk stratification of patients with severe ACS.
