Objective:
To investigate the correlation between magnetic resonance imaging-based vertebral bone quality (VBQ) score and screw loosening after dynamic pedicle screw fixation with polyetheretherketone (PEEK) rods, and evaluate its predictive value.
Methods:
A retrospective analysis was conducted on the patients who underwent dynamic pedicle screw fixation with PEEK rods from March 2017 to June 2022. Data on age, sex, body mass index, hypertension, diabetes, hyperlipidemia history, long-term smoking, alcohol consumption, VBQ score, L1–4 average Hounsfield unit (HU) value, surgical fixation length, and the lowest instrumented vertebra were collected. Logistic regression analysis was employed to assess the relationship between VBQ score and pedicle screw loosening (PSL).
Results:
A total of 24 patients experienced PSL after surgery (20.5%). PSL group and non-PSL group showed statistical differences in age, number of fixed segments, fixation to the sacrum, L1–4 average HU value, and VBQ score (p < 0.05). The VBQ score in the PSL group was higher than that in the non-PSL group (3.56 ± 0.45 vs. 2.77 ± 0.31, p < 0.001). In logistic regression analysis, VBQ score (odds ratio, 3.425; 95% confidence interval, 1.552–8.279) were identified as independent risk factors for screw loosening. The area under the receiver operating characteristic curve for VBQ score predicting PSL was 0.819 (p < 0.05), with the optimal threshold of 3.15 (sensitivity, 83.1%; specificity, 80.5%).
Conclusion
The VBQ score can independently predict postoperative screw loosening in patients undergoing lumbar dynamic pedicle screw fixation with PEEK rods, and its predictive value is comparable to HU value.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objective:To investigate the postoperative nursing needs and satisfaction with nursing services of elderly patients undergoing spinal surgery, analyze influencing factors, so as to provide a basis for formulating targeted nursing policies.Methods:From May 2021 to February 2022, 226 elderly patients who underwent spinal surgery in the Operating Room of Yantai City Yantaishan Hospital were selected. A questionnaire survey was conducted using the Nursing Needs and Satisfaction Scale for Elderly Inpatients. Multiple linear regression was used to analyze influencing factors. A total of 226 questionnaires were distributed, and 215 questionnaires were collected after excluding incomplete and invalid questionnaires, with an effective recovery rate of 95.13%.Results:Among 215 elderly patients, the total score of needs was (3.05±0.19) , and the total score of satisfaction was (2.51±0.78) . Among them, the highest score was for safety need with a score of (3.44±0.33) , and the lowest score was (1.96±0.73) obtained by actively asking and satisfying. The results of multiple linear regression analysis showed that the main influencing factors of patient nursing needs were self-care status, per capita monthly income of families, self-assessment of health status, and annual healthcare expenses ( P<0.05) . The main influencing factors of satisfaction were age and nursing grade ( P<0.05) . Conclusions:The nursing needs of elderly patients undergoing spinal surgery are high, but their satisfaction with nursing services is insufficient. Personalized nursing measures should be formulated based on the actual nursing needs of patients to improve the quality of nursing for elderly spinal surgery patients.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Objective:To investigate the effects of femtosecond laser assistcataract extraction on the levels of inflammatory factors in aqueous humor, corneal perception and high order aberration.Methods:Forty-eight patients (56 eyes) undergoing cataract surgery in the Shouguang People′s Hospital from June 2018 to February 2020 were enrolled in this study, and they were divided into observation group (24 patients and 27 eyes, femtosecond laser cataract phacoemulsification) and control group (24 patients and 29 eyes, coaxial microincision phacoemulsification) by random number table method. The levels of prostglndin E2 (PGE2), interleukin (IL)-6 and IL-1β in aqueous humor were detected before and after operation. Upper corneal and central corneal perception thresholds were recorded before surgery, 7 d after surgery, 1 month after surgery and 3 months after surgery. High order aberrations of the whole eye and cornea at 4mm pupil diameter before and after operation were recorded.Results:After operation, the levels of PGE2, IL-6 and IL-1β in aqueous humor in the observation group were lower than those in the control group: (45.62 ± 5.71) ng/L vs. (63.65 ± 5.62) ng/L, (15.25 ± 3.21) ng/L vs. (24.59 ± 6.13) ng/L, (17.16 ± 1.28) ng/L vs. (25.74 ± 4.62) ng/L, the differences were statistically significant ( P<0.05). The upper and central corneal perception threshold of observation group after operation for 7 d were higher than those in the control group: 4.55 ± 0.50 vs. 4.20 ± 0.33, 5.68 ± 0.49 vs. 5.52 ± 0.45, the differences were statistically significant ( P<0.05). The indexes of high order aberration of the whole eye decreased in the two groups ( P<0.05), while the indexes of cornea did not change significantly. The indexes of high order aberration of the whole eye and cornea between before and after surgery between the two groups had no significant differences ( P>0.05). Conclusions:Femtosecond laser assist cataractextraction can relieve inflammation, reduce the whole eye high order aberration, but not affect the cornea, and can improve corneal perception.
