ObjectivesTo evaluate the quality of guidelines on nutrition in liver disease from 2017 to 2019, and to interpret these guidelines so as to provide references for clinical practice.MethodsComputer-assisted literature searches in CNKI, VIP, WanFang Data, Medline (Ovid), The Cochrane Library, PubMed and Medlive databases were performed by two reviewers for guidelines on nutrition in liver disease from January 2017 to July 2019. Two reviewers extracted data and assessed the methodological quality of the included guidelines using AGREE II, separately. Meanwhile, the intraclass correlation coefficient (ICC) was used to assess the degree of consistency.ResultsFour guidelines were included with 2 from China and 2 from Europe. Their average standardised scores in the 6 domains of scope and purpose, stakeholder involvement, rigour of development, clarity, applicability and independence were 79.17%, 71.53%, 78.13%, 85.42%, 61.98% and 43.75%, respectively. The Chinese and European guidelines had similar recommendations for energy and other nutrients, apart from differences in recommendations for protein intake. The European guidelines considered that restricting protein intake was not beneficial for patients with hepatic encephalopathy, while the Chinese guidelines argued that patients with severe hepatic encephalopathy were required to reduce or limit their protein intake.ConclusionsAll 4 guidelines are of average quality and are required to be strengthened in the ‘independence’ domain. Currently, the only consensus on nutrition therapy for liver disease and guidelines on nutrition in end-stage liver disease are available for references in China, with lower quality scores than that of the European guidelines. Therefore, the evidence-based guidelines on nutrition in liver disease should be developed by Chinese national conditions as soon as possible to provide references for clinicians, nurses and clinical nutritionists, enableing them to implement nutrition screening, evaluation, nutritional therapy and follow-up management for patrents with liver disease.
ObjectiveTo evaluate the dietary and nutritional status of elderly patients with chronic non-infectious diseases in community hospitals in order to make a reasonable dietary pattern for these patients. MethodsA total of 179 elderly patients with chronic non-infectious diseases in a community hospital of Chengdu from January to September 2014 were collected, and we investigated them on their dietary status and basic personal information. The desirable dietary pattern (DDP) score was adopted to evaluate their dietary and nutritional status. ResultsDDP score of the 179 patients with chronic non-infectious diseases in the community hospital was 91.47, and the dietary quality was relatively good. While the DDP scores of animal food and edible oil exceeded the maximum allowable value, DDP scores of the staple food, fish, eggs, vegetables and fruits were lower than the expected scores. ConclusionIt is suggested that meat and other animal food intake be reduced and replaced by regular intakes of poultry, fish and shrimp, and the intake of staple food, eggs, vegetables, fruits be increased to ensure a balanced diet.
Objective To summarize the main methods and comprehensive effects of limited surgery combined with external fixation for the treatment of flail foot with sensory disorder of spina bifida sequela in adult. Method The clinical data of 22 cases (30 feet) of the adult spina bifida sequela who suffered from flail foot with sensory disorder and treated by limited surgery combined with external fixation were retrospectively analysed between January 2005 and December 2015. There were 14 males and 8 females with an age of 8-38 years (mean, 21.5 years). All 30 feet were distal ankle sensory loss, including 2 cases (2 feet) on the left side, 2 cases (2 feet) on the right side, and 18 cases (26 feet) on both sides. There was 1 foot accompanied by ulcerative plantar ulcers, and 3 feet lost their toes due to foot osteomyelitis in the weight-bearing area. Combined with 3 cases of hip dislocation, 3 cases of scoliosis, 4 cases of knee deformity, and 3 cases of ptosis. There were 5 cases of normal control of urine and stool, 10 cases of partial control of urine and stool, 6 cases of overflow urinary incontinence, and 1 case of cystostomy. According to X-ray film, the lesion of spina bifida was evaluated, the laminar insufficiency was located at L3-L5 in 8 cases, L5, S1 in 9 cases, and L3-S3 in 5 cases. In the patients, 12 feet were performed ankle joint arthrodesis, 10 feet subtalar arthrodesis, and 8 feet tibia-talus-calcaneus arthrodesis. Ilizarov external fixator was used in 18 feet, Hybrid fixator in 8 feet, Hybrid fixator and cannulate screws in 3 feet, and Ilizarov fixator and cannulate screws in 1 foot. Results All 22 patients were followed up 10-80 months (mean, 48.5 months). All ankle deformities were corrected effectively after operation, the middle and hind feet were stable, the plantar foot was restored, the whole foot was loaded, and the ulcer healed without recurrence. There were 2 cannulate screws ruptured in the subtalar arthrodesis, bone healed after screws break; no complication such as surgical infection, neurovascular injury, and so on happened. At last follow-up, based on the evaluation criteria of QIN Sihe lower limb deformity correction, the results were excellent in 15 feet, good in 9 feet, and fair in 6 feet, with an excellent and good rate of 80.0%. Conclusion The treatment of flail foot with sensory disorder of spina bifida sequela is more demanding. The limited surgeries combined with external fixation play an important role for recovering the stability of foot and ankle, better clinical results, and less complications.
ObjectiveTo compare the effect of aspirin+ticagrelor and aspirin+clopidogrel on graft patency one year after coronary artery bypass grafting (CABG).MethodsA total of 67 patients who received CABG in our department from January 2014 to September 2017 were included in this study (52 males and 15 females). They were randomly divided into a group A (aspirin+clopidogrel) and a group B (aspirin+ticagrelor). There were 34 participants in the group A (28 males and 6 females) and 33 patients in the group B (24 males and 9 females). All patients were invited for clinical follow-up and 64-slice multislice computed tomography angiography (MSCTA) analysis in 1 year postoperatively. Cardiovascular events, bleeding events and other adverse events were followed up.ResultsFour patients were lost to follow-up. Two patients died. A total of 61 patients (48 males and 13 females) completed coronary CTA, and 31 in the group A (25 males and 6 females) and 30 in the group B (23 males and 7 females). The total number of bridged vessels was 156 (59 internal thoracic artery bridges and 97 great saphenous vein bridges), including 79 in the group A (31 internal thoracic artery bridges and 48 great saphenous vein bridges) and 77 in the group B (28 internal thoracic artery bridges and 49 great saphenous vein bridges). Graft patency rate 1 year post CABG was 82.3% (65/79) in the group A and 92.2% (71/77) in the group B (P>0.05). Artery graft patency rate 1 year post CABG was 96.8% (30/31) in the group A and 96.4% (27/28) in the group B (P>0.05). Saphenous vein graft patency rate 1 year post CABG was 72.9% (35/48) in the group A and 89.8% (44/49) in the group B (P<0.05). Multivariable analysis with binary logistic regression showed ticagrelor use reduced graft occlusion (OR=0.282, 95%CI 0.093 to 0.862, P<0.05). There was no significant difference in adverse events between the two groups.ConclusionCompared with clopidogrel plus aspirin, ticagrelor added to aspirin after CABG may enhance the saphenous graft patency without the excess risk of bleeding 1 year post CABG.
Objective To identify and screen sensitive predictors associated with subscapularis (SSC) tendon tear and develop a web-based dynamic nomogram to assist clinicians in early identification and intervention of SSC tendon tear. Methods Between July 2016 and December 2021, 528 consecutive cases of patients who underwent shoulder arthroscopic surgery with completely MRI and clinical data were retrospectively analyzed. Patients admitted between July 2016 and July 2019 were included in the training cohort, and patients admitted between August 2019 and December 2021 were included in the validation cohort. According to the diagnosis of arthroscopy, the patients were divided into SSC tear group and non-SSC tear group. Univariate analysis, least absolute shrinkage and selection operator (LASSO) method, and 10-fold cross-validation method were used to screen for reliable predictors highly associated with SSC tendon tear in a training set cohort, and R language was used to build a nomogram model for internal and external validation. The prediction performance of the nomogram was evaluated by concordance index (C-index) and calibration curve with 1 000 Bootstrap. Receiver operating curves were drawn to evaluate the diagnostic performance (sensitivity, specificity, predictive value, likelihood ratio) of the predictive model and MRI (based on direct signs), respectively. Decision curve analysis (DCA) was used to evaluate the clinical implications of predictive models and MRI. Results The nomogram model showed good discrimination in predicting the risk of SSC tendon tear in patients [C-index=0.878; 95%CI (0.839, 0.918)], and the calibration curve showed that the predicted results were basically consistent with the actual results. The research identified 6 predictors highly associated with SSC tendon tears, including coracohumeral distance (oblique sagittal) reduction, effusion sign (Y-plane), subcoracoid effusion sign, biceps long head tendon displacement (dislocation/subluxation), multiple posterosuperior rotator cuff tears (≥2, supra/infraspinatus), and MRI suspected SSC tear (based on direct sign). Compared with MRI diagnosis based on direct signs of SSC tendon tear, the predictive model had superior sensitivity (80.2% vs. 57.0%), positive predictive value (53.9% vs. 53.3%), negative predictive value (92.7% vs. 86.3%), positive likelihood ratio (3.75 vs. 3.66), and negative likelihood ratio (0.25 vs. 0.51). DCA suggested that the predictive model could produce higher clinical benefit when the risk threshold probability was between 3% and 93%. ConclusionThe nomogram model can reliably predict the risk of SSC tendon tear and can be used as an important tool for auxiliary diagnosis.
ObjectiveTo systematically evaluate the efficacy of probiotics in preventing antibiotic-associated diarrhea (AAD) in aged people. MethodsPubMed, Web of Science, the Cochrane Database of Systematic Reviews, the Cochrane Controlled Trials Register, CNKI, VIP, and WANFANG electronic databases were searched for studies published, and references of included studies and reviews were screened from database inception to April 2014. Only randomized, controlled trials involving patients older than 65 years were included. Furthermore, only the trials which combined antibiotic administration and probiotic therapy for the prevention of AAD and Jadad score >3 were extracted. ResultsA total of eight articles containing 3 680 subjects (1 843 in the probiotic group, 1 837 people in the control group) met the inclusion criteria. Meta-analysis showed that there was no significant difference in the risk of antibiotic-associated diarrhea (AAD) between probiotics and control groups[RR=0.76, 95%CI (0.51, 1.13), P=0.17]. Further subgroup analysis found that compared with the control group, saccharomyces[RR=1.24, 95%CI (0.70, 2.19), P=0.46], lactobacillus[RR=0.59, 95%CI (0.31, 1.13), P=0.11], multi-probiotics combination[RR=0.58, 95%CI (0.24, 1.41), P=0.23] in the probiotics group were not significantly different. ConclusionThere is no evidence to support that probiotics can reduce the risk of AAD among aged people administrated with antibiotics therapy.
Heart rate variability (HRV) is the difference between the successive changes in the heartbeat cycle, and it is produced in the autonomic nervous system modulation of the sinus node of the heart. The HRV is a valuable indicator in predicting the sudden cardiac death and arrhythmic events. Traditional analysis of HRV is based on a multi-electrocardiogram (ECG), but the ECG signal acquisition is complex, so we have designed an HRV analysis system based on photoplethysmography (PPG). PPG signal is collected by a microcontroller from human’s finger, and it is sent to the terminal via USB-Serial module. The terminal software not only collects the data and plot waveforms, but also stores the data for future HRV analysis. The system is small in size, low in power consumption, and easy for operation. It is suitable for daily care no matter whether it is used at home or in a hospital.
Objective To evaluate the feasibility and safety of percutaneous endoscopic technique in the treatment of intraspinal cement leakage after percutaneous vertebroplasty (PVP). Methods Between May 2014 and March 2016, 5 patients with lower limb pain and spinal cord injury caused by intraspinal cement leakage after PVP, were treated with percutaneous endoscopic spinal decompression. Of 5 cases, 3 were male and 2 were female, aged from 65 to 83 years (mean, 74.4 years). The course of disease was 10-30 days (mean, 16.2 days). Imageological examinations confirmed the levels of cement leakage at T 12, L 1 in 3 cases, and at L 1, 2 in 2 cases; bilateral sides were involved in 1 case and unilateral side in 4 cases. Two patients had lower limb pain, whose visual analogue scale (VAS) were 8 and 7; 3 patients had lower extremities weakness, whose Japanese Orthopedic Association (JOA) 29 scores were 18, 20, and 19. According to American Spinal Injury Association (ASIA) impairment scale, neural function was rated as grade E in 2 cases and grade D in 3 cases. Results The operation time was 55-119 minutes (mean, 85.6 minutes), and the blood loss was 30-80 mL (mean, 48 mL). CT scan and three-dimensional (3D) reconstruction at 1 day after operation showed that cement leakage was removed in all patients. Five cases were followed up 6-21 months (mean, 12 months). In 2 patients with lower limb pain, and VAS score was significantly decreased to 2 at last follow-up. In 3 patients with lower extremities weakness, the muscle strength was improved progressively, and the JOA29 scores at last follow-up were 21, 23, and 22. Conclusion Percutaneous endoscopic technique for intraspinal cement leakage after PVP is safe, effective, and feasible.
