Meta Analysis Comparative Study
Comparison of the efficacy and safety of shockwave lithotripsy, retrograde intrarenal surgery, percutaneous nephrolithotomy, and minimally invasive percutaneous nephrolithotomy for lower-pole renal stones: A systematic review and network meta-analysis.
Shock wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), percutaneous nephrolithotomy (PCNL), and minimally invasive PCNL are currently therapeutic options for lower-pole renal stones (LPS). However, the optimal treatment for LPS remains unclear. A comprehensive evaluation of the efficacy and safety of each intervention is needed to inform clinical decision-making. This study aimed at assessing the efficacy and safety of different interventions for LPS. ⋯ PCNL was associated with the best stone free rate for LPS regardless of age, sex, and stone size. Each treatment achieved a similar complication rate compared with the others. Future large-scale RCTs are warranted to identify the most beneficial management for renal stones at a more complicated location.

Number of studies have been performed to evaluate the relationship between the cytotoxic T-lymphocyte associated antigen-4 (CTLA-4) gene variant rs5742909 polymorphism and cervical cancer risk, but the sample size was small and the results were conflicting. This meta-analysis was conducted to comprehensively evaluate the overall association. ⋯ our meta-analysis supports that the CTLA-4 gene variant rs5742909 polymorphism might contribute to individual susceptibility to cervical cancer in Asians.

Antiplatelet agents have been administered to patients with acute ischemic stroke after endovascular therapy. This study was designed to provide initial data to compare thromboelastography (TEG) with the conventional coagulation test (CCT) to analyze the coagulation function of antiplatelet drugs in such patients. The present retrospective cohort study included 240 patients who received endovascular therapy from September 2012 to December 2017. ⋯ The 3 pairs of parameters (R and APTT, K and APTT, and α angle and FIB) were in agreement for identifying hypercoagulability, while R and APTT, K and APTT, K and PLT, and α angle and PLT were in agreement for identifying hypocoagulability. The AUROC of parameter R for detecting symptomatic intracranial hemorrhage was 0.817, while that of parameter FIB for predicting early neurological deterioration was 0.887. Parameter FIB derived from CCT might be advantageous for evaluating early neurological deterioration, while parameter R detected by TEG might be superior for evaluating symptomatic intracranial hemorrhage.

To evaluate the improvement of radiologist performance in detecting bone metastases at follow up low-dose computed tomography (CT) by using a temporal subtraction (TS) technique based on an advanced nonrigid image registration algorithm. Twelve patients with bone metastases (males, 5; females, 7; mean age, 64.8 ± 7.6 years; range 51-81 years) and 12 control patients without bone metastases (males, 5; females, 7; mean age, 64.8 ± 7.6 years; 51-81 years) were included, who underwent initial and follow-up CT examinations between December 2005 and July 2016. Initial CT images were registered to follow-up CT images by the algorithm, and TS images were created. ⋯ The changes in the absolute value of CT attenuations in true-positive lesions were significantly larger than those in false-negative lesions (P < .001). Using TS, segment-based sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of the readout with TS were 66.7%, 98.9%, 94.4%, 90.9%, and 94.8%, respectively. The TS images can significantly improve the radiologist's performance in the detection of bone metastases on low-dose and relatively thick-slice CT.

This study aimed to evaluate the risk of dementia after distal radius, hip, and spine fractures. Data from the Korean National Health Insurance Service-National Sample Cohort were collected for the population ≥ 60 years of age from 2002 to 2013. A total of 10,387 individuals with dementia were matched for age, sex, income, region of residence, and history of hypertension, diabetes, and dyslipidemia with 41,548 individuals comprising the control group. ⋯ The adjusted ORs for dementia were higher in the distal radius, hip, and spine fracture group than in the non-fracture group (adjusted OR = 1.23, 95% CI = 1.10 -1.37, P < .001 for distal radius fracture; adjusted OR = 1.64, 95% CI = 1.48 - 1.83, P < .001 for hip fracture; adjusted OR = 1.31, 95% CI = 1.22 - 1.41, P < .001 for spine fracture). The results in subgroup analyses according to age, sex and region of residence were consistent. Distal radius, hip, and spine fractures increase the risk of dementia.
