ABSTRACT

BACKGROUND: Inpatient prevalence of Parkinson’s disease (PD) delirium varies widely across the literature. Delirium in general older populations is associated with adverse outcomes, such as increased mortality, dementia, and institutionalisation. However, to date there are no comprehensive prospective studies in PD delirium. This study aimed to determine delirium prevalence in hospitalised PD participants and the association with adverse outcomes, compared to a control group of older adults without PD.

METHODS: Participants were hospitalised inpatients from the ‘Defining Delirium and its Impact in Parkinson’s Disease’ and the ‘Delirium and Cognitive Impact in Dementia’ studies comprising 121 PD participants and 199 older adult controls. Delirium was diagnosed prospectively using the Diagnostic and Statistical Manual of Mental Disorders 5th Edition criteria. Outcomes were determined by medical note reviews and/or home visits 12 months post hospital discharge.

RESULTS: Delirium was identified in 66.9% of PD participants compared to 38.7% of controls (p < 0.001). In PD participants only, delirium was associated with a significantly higher risk of mortality (HR = 3.3 (95% confidence interval [CI] = 1.3-8.6), p = 0.014) and institutionalisation (OR = 10.7 (95% CI = 2.1-54.6), p = 0.004) 12 months post-discharge, compared to older adult controls. However, delirium was associated with an increased risk of developing dementia 12 months post-discharge in both PD participants (OR = 6.1 (95% CI = 1.3-29.5), p = 0.024) and in controls (OR = 13.4 (95% CI = 2.5-72.6), p = 0.003).

CONCLUSION: Delirium is common in hospitalised PD patients, affecting two thirds of patients, and is associated with increased mortality, institutionalisation, and dementia. Further research is essential to understand how to accurately identify, prevent and manage delirium in people with PD who are in hospital.

ABSTRACT

BACKGROUND AND AIMS: The European Association for the Study of the Liver introduced a clinical pathway (EASL CP) for screening significant/advanced fibrosis in people at risk of steatotic liver disease (SLD). We assessed the performance of the first-step FIB4 EASL CP in the general population across different SLD risk groups (MASLD, Met-ALD and ALD) and various age classes.

METHODS: We analysed a total of 3372 individuals at risk of SLD from the 2017-2018 National Health and Nutrition Examination Survey (NHANES17-18), projected to 152.3 million U.S. adults, 300,329 from the UK Biobank (UKBB) and 57,644 from the Biobank Japan (BBJ). We assessed liver stiffness measurement (LSM) ≥8 kPa and liver-related events occurring within 3 and 10 years (3/10 year-LREs) as outcomes. We defined MASLD, MetALD, and ALD according to recent international recommendations.

RESULTS: FIB4 sensitivity for LSM ≥ 8 kPa was low (27.7%), but it ranged approximately 80%-90% for 3-year LREs. Using FIB4, 22%-57% of subjects across the three cohorts were identified as candidates for vibration-controlled transient elastography (VCTE), which was mostly avoidable (positive predictive value of FIB4 ≥ 1.3 for LSM ≥ 8 kPa ranging 9.5%-13% across different SLD categories). Sensitivity for LSM ≥ 8 kPa and LREs increased with increasing alcohol intake (ALD>MetALD>MASLD) and age classes. For individuals aged ≥65 years, using the recommended age-adjusted FIB4 cut-off (≥2) substantially reduced sensitivity for LSM ≥ 8 kPa and LREs.

CONCLUSIONS: The first-step FIB4 EASL CP is poorly accurate and feasible for individuals at risk of SLD in the general population. It is crucial to enhance the screening strategy with a first-step approach able to reduce unnecessary VCTEs and optimise their yield.

ABSTRACT

OBJECTIVES: Compare the surgical outcomes, safety, stone free rate, hospital stay, and complication of prone and supine PCNL in case of complex renal stone.

MATERIALS AND METHODS: This is an observational study conducted in our institute, it consist of 120 patients over the period of 2 years from July 2021 to June 2023, all the patients were divided into two groups: 60 patients underwent modified supine percutaneous nephrolithotomy (PCNL) and remaining 60 patients underwent standard prone PCNL. The measured data included operative time, number of punctures, blood loss, stone-free rate, length of hospital stays, and rate of complications.

RESULTS: The two groups were comparable in mean age, male to female ratio, number of punctures, number of tract, size of tract, residual calculi in follow up period, blood transfusion, re-do surgery, chest complication, hospital stay, and postoperative fever and pain. The mean operating time was 1.59 h in supine PCNL and 2.49 h in prone PCNL. The p value was significant (p = 0.001).

CONCLUSIONS: By this study we observed that the supine PCNL is associated with statistically significant reduced operating time as compared to conventional prone PCNL with advantages of not putting the patient in prone position. The postoperative complications such as pain and fever were not significant when compared in both groups. We conclude our study and found that, the supine PCNL is an equally effective in treating complex renal stone as compared to prone PCNL.

ABSTRACT

Similar clinical features make the differential diagnosis difficult, particularly between lung cancer and pulmonary tuberculosis (TB), without pathological evidence for patients with concomitant TB infection. Our study aimed to build a nomogram to predict malignant pulmonary lesions applicable to clinical practice. We retrospectively analyzed clinical characteristics, imaging features, and laboratory indicators of TB infection patients diagnosed with lung cancer or active pulmonary TB at Xiangya Hospital of Central South University. A total of 158 cases from January 1, 2018 to May 30, 2019 were included in the training cohort. Predictive factors for lung cancer were screened by a multiple-stepwise logistic regression analysis. A nomogram model was established, and the discrimination, stability, and prediction performance of the model were analyzed. A total of 79 cases from June 1, 2019, to December 30, 2019, were used as the validation cohort to verify the predictive value of the model. Eight predictor variables, including age, pleural effusion, mediastinal lymph node, the number of positive tumor markers, the T cell spot test for TB, pulmonary lesion morphology, location, and distribution, were selected to construct the model. The corrected C-statistics and the Brier scores were 0.854 and 0.130 in the training cohort, and 0.823 and 0.163 in the validation cohort. Calibration plots showed good performance, and decision curve analysis indicated a high net benefit. In conclusion, the nomogram model provides an effective method to calculate the probability of lung cancer in TB infection patients, and it has excellent discrimination, stability, and prediction performance in detecting a malignant diagnosis of undiagnosed pulmonary lesions.

ABSTRACT

Background: In the absence of head-to-head comparative data from randomized controlled trials, indirect treatment comparisons (ITCs) may be used to compare the relative effects of treatments versus a common comparator (either placebo or active treatment). For acute pain management, the effects of oliceridine have been compared in clinical trials to morphine but not to fentanyl or hydromorphone. Aim: To assess the comparative safety (specifically differences in the incidence of nausea, vomiting and opioid-induced respiratory depression [OIRD]) between oliceridine and relevant comparators (fentanyl and hydromorphone) through ITC analysis. Methods: A systematic literature review identified randomized clinical trials with oliceridine versus morphine and morphine versus fentanyl or hydromorphone. The ITC utilized the common active comparator, morphine, for the analysis. Results: A total of six randomized controlled trials (oliceridine – 2; hydromorphone – 3; fentanyl – 1) were identified for data to be used in the ITC analyses. The oliceridine data were reported in two studies (plastic surgery and orthopedic surgery) and were also reported in a pooled analysis. The ITC focused on nausea and vomiting due to limited data for OIRD. When oliceridine was compared with hydromorphone in the ITC analysis, oliceridine significantly reduced the incidence of nausea and/or vomiting requiring antiemetics compared with hydromorphone (both orthopedic surgery and pooled data), while results in plastic surgery were not statistically significant. When oliceridine was compared with hydromorphone utilizing data from Hong, the ITC only showed a trend toward reduced risk of nausea and vomiting with oliceridine that was not statistically significant across all three comparisons (orthopedic surgery, plastic surgery and combined). An ITC comparing oliceridine with a study of fentanyl utilizing the oliceridine orthopedic surgery data and combined orthopedic and plastic surgery data showed a trend toward reduced risk that was not statistically significant. Conclusion: In ITC analyses, oliceridine significantly reduced the incidence of nausea and/or vomiting or the need for antiemetics in orthopedic surgery compared with hydromorphone and a non-significant trend toward reduced risk versus fentanyl.

ABSTRACT

AIM: To share the surgical outcomes of 31 patients who underwent endoscopic endonasal transsphenoidal surgery (EETS) at a single center.

MATERIAL AND METHODS: This retrospective analysis of 31 craniopharyngioma cases (2013-2022) with a minimum 6-month follow-up included demographic data, preoperative findings, postoperative resection volumes, recurrence rates, pathological diagnoses, and complications.

RESULTS: Herein, 34 EETS surgeries were performed on 31 patients (12 males, 19 females). The presenting symptoms included visual loss (58%), hypopituitarism (54.8%), and diabetes insipidus (25.8%). Gross total resection was achieved in 87% of the patients, with 64.5% total and 22.5% near-total resection. Total resection prevented recurrences, contrasting with 75% recurrence in the subtotal resection patients (p=0.000). The primary patients showed 73.1% total resection, while only 20% of the recurrent patients achieved it (p=0.049). When comparing the first 16 cases with the last 15 cases in terms of surgical experience, the rates of resection (p=0.040) and recurrence-free survival (p=0.020) in the last 15 cases were statistically significant. Patients with preoperative visual loss demonstrated 94.4% improvement or stability postoperatively. Postoperative complications included hypopituitarism (71.4%), permanent diabetes insipidus (60.8%), worsening vision (6.5%), cerebrospinal fluid leakage (9.7%), meningitis (6.5%), and a 3.2% perioperative mortality rate.

CONCLUSION: This study underscores the role of surgical resection in craniopharyngiomas, emphasizing the impact of surgical experience on recurrence-free survival. Primary surgery, with minimal complications and maximal resection, is crucial in managing recurrence challenges. Endoscopic endonasal transsphenoidal surgery, particularly in experienced centers, offers advantages such as panoramic vision and access to the third ventricle base, facilitating total and near-total resection and extending recurrence-free survival.

ABSTRACT

AIM: To examine the effect of cerebellar damage on the process of fracture healing.

MATERIAL AND METHODS: A total of forty-two male rats were selected at random and subsequently allocated into three distinct groups. The experimentals were divided into two subgroups within each group, with the intention of sacrificing them during the third and sixth weeks. Group 1 had isolated femoral fracture, Group 2 had femoral fracture after craniotomy, and Group 3 had femoral fracture accompanying cerebellar injury after craniotomy. Left femoral fractures in rats in all groups were treated using an intramedullary Kirschner wire. Radiological, histological, and biochemical evaluations were conducted at 3 and 6 weeks to assess the processes of fracture healing. To determine the effects of fracture healing and cerebellar injury on oxidant-antioxidant systems, catalase (CAT), malondialdehyde, superoxide dismutase (SOD), and glutathione peroxidase (GPx) activities were measured.

RESULTS: Between the time frame of 3 to 6 weeks, Group 3 had higher radiography scores, alkaline phosphatase levels, callus/ diaphyse ratio, callus improvement, and bone mineral density in comparison to the other groups. The activity of SOD was found to be statistically negligible in all groups, suggesting that SOD does not have a substantial impact on fracture healing in cerebellar injury. However, notable increases in the activity of GPx and CAT enzymes were observed, showing their considerable involvement in the process of fracture healing.

CONCLUSION: Cerebellar injury reduces the oxidative stress in the fracture area and contributes positively to fracture healing by means of radiologically, biochemically and histopathologically.

ABSTRACT

AIM: To examine the effects of regulating increased blood glucose levels on plasma ET-1 levels after severe head trauma in rats.

MATERIAL AND METHODS: Traumatic diffuse brain injury-induced rats were followed for 7 days and were randomly divided into two groups of 36 rats. Pre- and posttraumatic blood glucose and ET-1 levels were measured in group 1 (control). Posttraumatic blood glucose levels were maintained at normal levels using insulin and both blood glucose and ET-1 levels were measured at 2, 6, 12, 24, and 48 h and 7 days posttrauma in group 2. The study excluded animals that died and had skull fractures.

RESULTS: Posttraumatic plasma ET-1 levels (n=36) were significantly higher than baseline values in group 1 (p < 0.05). ET-1 levels in group 2 at the 7-day follow-up after trauma were significantly higher than baseline values (n=36) (p < 0.05). However, the increased ET-1 levels were statistically significantly lower in group 2 than in group 1 (p < 0.05).

CONCLUSION: The increased ET-1 levels were significantly prevented by keeping blood glucose levels within normal limits with insulin after severe head trauma. Thus, secondary injury to cerebral blood flow can be prevented by reducing the occurrence of vasospasm that starts in the early posttraumatic period or by stimulating the release of nitric oxide. Therefore, further studies on the role of ET-1 and insulin in developing secondary injuries after severe head trauma would be beneficial.

ABSTRACT

AIM: To evaluate the outcomes of dynamic stabilization in the multilevel degenerative spondylotic spine, and to compare the two dynamic systems (Dynesys® and Orthrus®) to reveal the increasing role of dynamic systems in the management of the degenerative spine.

MATERIAL AND METHODS: A total of 74 patients who received dynamic stabilization for degenerative pathologies were retrospectively analyzed. Demographic details: preoperative data including neurological status, pain scores, and radiology; and intraoperative data including blood loss, duration of surgery, complications, and postoperative data including the neurologic status, duration of hospital stay, and pain scores were examined.

RESULTS: Patients in both groups showed statistically significant improvements in their Visual Analog Scale and Oswestry Disability Index scores. Significant corrections of thoracic kyphosis (T2-T12), the sagittal vertical axis, and T10-L2 thoracolumbar kyphosis were obtained in our cohort (p < 0.05). A total of 4 patients received revision surgery due to screw loosening. Patients were discharged after 3-4 days and mobilized on the first postoperative day.

CONCLUSION: We did not experience any serious issues in terms of stabilization in the cases in which we employed both systems. Our patients’ clinical results were satisfactory in both systems. Existing systems can be used safely even in long-segment stabilization surgeries.
