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.
Objective To explore if the modified unilaterally-open expansive laminoplasty using bridge grafting and reconstructing posterior ligamentous complex methods is effective in preventing persisting axial symptoms, restriction of neck motion, and loss of cervical curvature. Methods From June 2000 to October 2005, 138 patients with cervical spondylotic myelopathy underwent this procedure. Of them, 78 who were followed for more than 2 years (group A) were included in this study. Another 69 patients who underwent conventional unilaterally opendoor laminoplasty served as controls(groupB). The JOA scores and the incidence of newly developed or deteriorated axial symptoms were recorded. Preoperative and postoperative ranges of neck motion were measured on lateral flexion and extension radiographs. Preoperative and postoperative cervical curvature indices were calculated according to Ishihara’s method. Results The patients of group A were followed 24-44 months (mean 33 months), and the patients of group B were followed 2453 months(mean 35 months). The operative time was 114±20 min in group A and 70±25 min in group B,showing statistically significant difference(P＜0.05). The operative blood loss was 280±72 ml in group A and 210±80 ml in group B(P＞0.05). Accordingto JOA scoring, the average recovery rates were 67.0%±17.3% in group A and 65.0%±21.4% in group B(P＞0.05). Postoperative development or deterioration of axial symptoms occurred in 12% of patients in group A and 51% of patients in group B, showing statistically significant difference(P＜0.05). Postoperative range of neck motion was 88.0%±10.1% of the preoperative one in group A and 64.0%±16.3% in group B(P＜0.05). There was no significant difference between preoperative(15.3±8.2) and postoperative(13.5±9.3) cervical curvature index in group A, whereas the mean value of postoperative index (11.1±5.7) was significantly smaller than that of preoperative one (17.2±13.5) in group B (Plt;0.05). Conclusion This new procedure was less invasive to the posterior extensor mechanism than the conventional unilaterally-open laminoplasty and was effective in preventing postoperative morbidities.
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 develop altering intake managing symptoms (AIMS) dietary intervention and evaluate its effects on nutritional status and dietary compliance for patients after gastrectomy.MethodsFrom April 2017 to July 2018, 176 patients underwent the gastrectomy in the Xijing Hospital of Air Force Military Medical University were selected, then were divided into an AIMS group and a control group by the Excel 2007 random function method. The AIMS group was intervened by the AIMS dietary intervention, the control group was given the routine diet management. The body mass, body mass index (BMI), albumin, and dietary intake at the admission, on the 2nd week and the 3rd month after the discharge were compared between the two groups. The nutritional status of the two groups was assessed by the PG-SGA scale. The diet-related symptoms and dietary compliance of the two groups were assessed by the dietary related symptoms scale and the dietary compliance scale.ResultsA total of 176 eligible patients were enrolled in this study, including 92 patients in the AIMS group and 84 patients in the control group. There were no significant differences in the baseline data such as the gender, age, educational level, occupation, disease type, surgical method, tumor TNM stage, and pathological differentiated type between the two groups (P>0.050). There were no significant differences in the body mass, BMI, and albumin between the AIMS group and the control group before and after the dietary intervention (P>0.050). The PG-SGA score, diet-related symptom score, and dietary compliance score had significant differences between on the 2nd week or the 3rd month after the discharge and at the admission in the AIMS group and the control group (P<0.050), which had significant differences on the 2nd week or the 3rd month after the discharge between the AIMS group and the control group (P<0.001). The dietary intake of the AIMS group was significantly higher than that of the control group on the 3rd month after the discharge (P<0.001). The complications incidences of total diet-related symptoms was 5.5% (5/91) and 14.6% (12/82) in the AIMS group and the control group, respectively, the difference was statistically significant (P=0.047).ConclusionUsing AIMS dietary intervention for patients after radical gastrectomy can significantly improve their overall nutritional status and improve dietary compliance.
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.
The postictal state which describes changes in behavior, motor function, and neuropsychological performance that occur after a seizure and persist until these variables return to their normal baseline, which can take anywhere from a few seconds to a few hours to a few days. The degree and intensity of the postictal state significantly affects the patient's quality of life and is strongly associated with the patient's rating of the severity of the seizure, but receives little attention in the treatment of epilepsy, and anti-seizure medications prevent postictal events by making the patient seizures-free, or will attenuate or shorten the time after the seizure. Therefore, it is of great clinical significance to evaluate the efficacy of anti-seizure medications in the post-seizure state. This article reviews the effects of the main anti-seizure medications on the postictal state
ObjectiveTo analyze the symptom characteristics and influencing factors in order to provide reference for symptom management of patients with esophageal cancer after operation.MethodsA total of 216 esophageal cancer patients, including 180 males and 36 females with an average age of 63.7±8.3 years, who underwent surgical operation in our hospital from March to October 2018 were recruited and investigated with self-designed symptom questionnaire at 1 month after surgery.ResultsThe top five symptoms were acid reflux (48.6%), cough (42.6%), dysphagia (40.7%), hoarseness (12.0%), and diarrhea (11.6%). Women were more prone to acid reflux (OR=2.053), fatigue (OR=1.932), chest pain (OR=3.681), sleep disturbance (OR=2.419), abdominal pain (OR=3.882), nausea (OR=3.014) and vomiting (OR=2.505). Patients over 60 years were more prone to dysphagia (OR=2.274). Patients with lower thoracic esophageal cancer had a higher incidence of dysphagia compared with patients with carcinoma of esophagogastric junction (OR=0.326). Patients who had neoadjuvant chemotherapy were more likely to suffer acid reflux (OR=1.594). Open surgery (OR=3.681) and neoadjuvant radiotherapy (OR=2.495) were the risk factors of chest pain.ConclusionThere are many symptoms in patients with esophageal cancer after operation, and the occurrence of symptoms is closely related to gender, age, tumor location, surgical procedure and neoadjuvant chemoradiotherapy.
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.
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.
Objective
To investigate the early effectiveness of total percutaneous endovascular aneurysm repair (TPEVAR) in treating asymptomatic abdominal aortic aneurysm (AAAA) by comparing with surgical femoral cutdown endovascular aneurysm repair (SFCEVAR).
Methods
Between January 2010 and May 2011, 41 cases of AAAA were treated with TPEVAR in 26 cases (TPEVAR group) and with SFCEVAR in 15 cases (SFCEVAR group). The maximum tumor diameter ranged from 3.5 to 9.2 cm (mean, 5.7 cm) in TPEVAR group, and ranged from 3.5 to 10.0 cm (mean, 6.9 cm) in SFCEVAR group. There was no significant difference in gender or age between 2 groups (P gt; 0.05).
Results
All patients underwent EVAR successfully. The patients were followed up 6-23 months (mean, 13.5 months). No significant difference was found in the outer diameters of the delivery system for main body and iliac leg, operation time, contrast media dosage, hospitalization days, or postoperative hospitalization days between 2 groups (P gt; 0.05). The patients of SFCEVAR group had more bleeding volume and longer ICU stay than patients of TPEVAR group (P lt; 0.05). The incidence of minor complication was 7.7% (2/26) in TPEVAR group and 33.3% (5/15) in SFCEVAR group, showing no significant difference between 2 group (χ2=4.42, P=0.08); the incidence of major complication in SFCEVAR group (20.0%, 3/15) was significantly higher than that in TPEVAR group (0) (χ2=5.61, P=0.02).
Conclusion
TPEVAR shows safer and more effective than SFCEVAR in treating AAAA.
