To analyze the effectiveness of posterior pedicle screw system combined with interbodyfusion in treating lumbar spondylol isthesis. Methods Between January 2005 and January 2009, 26 patients with lumbar spondylol isthesis underwent posterior pedicle screw system combined with interbody fusion, including 11 males and 15 females with an average age of 56.8 years (range, 36-73 years). The disease duration was 7 months to 11 years. The affected lumbars were L3 in 3 cases, L4 in 12 cases, and L5 in 11 cases. According to the Meyerding evaluating system, 21 cases were classified as degree III, 5 cases as degree III-IV, and 1 case as degree IV. The cl inical results were investigated by measuring radiographic measurements, including Taillard index, Boxall index, sl i pping angle, lumbar lordosis angle,and intervertebral height index preoperatively, immediately, 2 weeks and 3 months postoperatively, respectively. SUK’s criteria was used to judge bone graft fusion. Results Primary heal ing of the incisions was achieved in all cases. Allpatients were followed up 25.8 months on average (range, 10-51 months). There were significant differences in Taillardindex, Boxall index, sl i pping angle, lumbar lordosis angle, and intervertebral height index between preoperatively andimmediately, 2 weeks, 3 months after operation (P lt; 0.05). Bone graft fusion was achieved at 3-8 months after operation(mean, 3.5 months); and the fusion rate was 100%. According to Japanese Orthopedic Association (JOA) scoring, theresults were excellent in 17 cases, good in 7 cases, fair in 1 case, and poor in 1 case; and the excellent and good rate was 92.3%. Compl ications occurred in 2 cases, including nail or rod breakage and nerve injury, and they were cured aftertreatment. Conclusion Posterior pedicle screw system combined with interbody fusion treating lumbar vertebralspondylol isthesis can afford sol id internal fixation and achieve a satisfactory reduction, so it maybe an ideal procedure and a worthy recommended method for treating lumbar spondylol isthesis.
ObjectiveTo interpret the interpretation of intervention description and reporting standards (TIDieR), and further present the domestic and international application status of TIDieR based on knowledge graphs. And to provide references and inspirations for standardized reporting of intervention studies. MethodsTIDieR-related literature published in Chinese and English databases such as CNKI, WanFang Data, PubMed, and Web of Science were searched from 2014 to 2024, and visual analysis was conducted using CiteSpace6.3.R1 bibliometric software. ResultsTIDieR consisted of 12 entries, including abbreviated intervention name, implementation rationale, implementation materials, implementation process, implementer, implementation method, implementation site, implementation time and intensity, personalized plan, plan changes, expected effects, and actual effects. The bibliometric analysis included 94 English-language papers and 5 Chinese-language papers. The application of TIDieR was relatively widespread overseas, mainly involving health care, rehabilitation, and digital health fields. ConclusionTIDieR can ensure the standardization and reproducibility of intervention research reports. However, domestic scholars still apply TIDieR less frequently. It is necessary to gradually promote and strengthen the application of TIDieR in future intervention studies, thereby improving the transparency and quality of intervention research reports.
Objective To explore the pathogen distribution and the characteristics of antibiotics use of patients with positive bile culture in order to provide evidence for appropriate antibiotic use. Methods Using a patient-based approach, the clinical and laboratory data of patients with positive bile culture between December 1st 2016 and November 30th 2017 were retrospectively analyzed. The pathogen distribution and antibiotics use of patients with bililary duct infections and colonizations were analyzed. Multidrug-resistant organism infections of patients with bililary duct infections were studied. Results There were 299 submitted bililary samples and in which 158 were culture-positive (52.8%). One hundred and ten strains of pathogens were found in 79 patients with positive bile culture, including 66 strains of Gram-negative (G–) organisms (60.0%), 37 strains of Gram-positive (G+) organisms (33.6%), and 7 strains of fungi (6.4%). The top three G– organisms were Escherichia coli (25 strains, 22.7%), Klebsiella pneumoniae (9 strains, 8.2%), and Acinetobacter baumanii (7 strains, 6.4%). The top three G+ organisms were Enterococcus faecium (10 strains, 9.1%), Enterococcus faecalis (6 strains, 5.5%), and coagulase negativeStaphylococcus (6 strains, 5.5%). The number of patients with bililary duct infections and colonizations were 42 and 37, respectively, with pathogens occupied mainly by G– bacteria. Ten strains of multidrug-resistant organisms were isolated from patients with bililary duct infections. Compared to patients with non-multidrug-resistant organism infections, the length of antibiotics use was longer in patients with multidrug- resistant organism infections (t=2.129, P=0.039). The rate of target therapy for antibiotics in patients with bililary duct infections was 76.2%. The rate of proper antibiotics use was 16.2% before positive bile culture and 78.4% after positive bile culture in patients with bililary duct colonizations. Conclusions Pathogens isolated from bile culture of infection and colonization are predominantly G– organisms. The bile culture and blood culture should be done for patients with suspected bililary duct infection. Infection and colonization should be distinguished for positive bile culture and antibiotic should be chosen according to drug susceptibility test results.
