Objective To compare the distribution characteristics of retinal capillary non-perfusion areas(NPAs)across different layers and regions in patients with neovascular glaucoma(NVG)secondary to proliferative diabetic retinop-athy(PDR)versus those with PDR alone through wide-field swept-source optical coherence tomography angiography(SS-OCTA)and to analyze the impacts of NPAs on the development of NVG.Methods This prospective cross-sectional study enrolled 33 patients with PDR(33 eyes,the PDR group)and 30 patients with NVG(30 eyes,the PDR+NVG group)diag-nosed at Affiliated Hospital of Shandong Second Medical University(formerly Weifang Medical University)from January 2022 to June 2023.The fundus examination was performed using SS-OCTA,and the NPA boundaries of the superficial capil-lary plexus(SCP)and deep capillary plexus(DCP)of the retina were manually delimited with the aid of ImageJ.The reti-na was divided based on two methods.Specifically,according to different concentric circles,the retina could be divided in-to the foveal area,parafoveal area,perifoveal area,annulus6-9,annulus9-12,annulus12-retinal boundary;besides,the ret-ina could also be divided into four quadrants(supratemporal,infratemporal,supranasal,and infranasal quadrants)based on the horizontal and vertical lines centered on the macular fovea.Based on that,the NPA area and ischemia index(ISI)in each layer and subdivision of the two groups of patients were counted.Additionally,the NPA and ISI in different concentric circles and different quadrants of the SCP and DCP were compared between the two groups.Moreover,the distribution characteristics of NPAs as well as the effect of NPAs on NVG were analyzed.Results(1)The NPA area and ISI in the DCP were larger than those in the SCP in both groups(all P＜0.001);the NPA area and ISI in the SCP and DCP of patients in the PDR+NVG group were larger than those in the PDR group(all P＜0.001).(2)In the supratemporal,infratemporal,supranasal,and infranasal quadrants,the NPA area and ISI in the SCP and DCP of patients in the PDR+NVG group were larger than those in the PDR group(all P＜0.01).The NPA area in the inferotemporal quadrant was the largest in the SCP and DCP,respectively,within each group(all P＜0.01).(3)The differences in the NPA area and ISI between the two groups were statistically significant in the annulus6-9,annulus9-12,and annulus12-retinal boundary in the SCP and DCP(all P＜0.01).The differences in the NPA area and ISI were statistically significant between different annular subdivisions in the SCP and DCP within each group(all P＜0.001).The multiple comparison results showed that the NPA area and ISI of the annulus12-retinal boundary in the SCP and DCP were larger than those in other annuli in both groups(all P＜0.05).The NPA area and ISI of the annulus9-12 were larger than those of the parafoveal and perifoveal areas;the NPA area and ISI of the annulus6-9 were larger than those of the parafoveal area(all P＜0.05).There was no statistically significant differ-ence in the NPA area and ISI in the remaining annuli(all P＞0.05).(4)The multivariate logistic regression analysis showed that the NPA area and ISI in the subnasal quadrant of the SCP were negatively correlated with the risk of NVG sec-ondary to PDR(P=0.036 and 0.038).The increased NPA area and ISI in the subnasal quadrant of the DCP were risk fac-tors for NVG secondary to PDR,and they may increase the risk of NVG(P=0.029 and 0.028).Conclusion The in-creased NPA area and ISI in the subnasal quadrant of the DCP were risk factors for secondary NVG in patients in the PDR group.

Objective To systematically evaluate the published models in prediction of the risk of lung infections in elderly patients with hip fracture so as to provide a guidance for medical workers in selection or development of suitable risk prediction models.Methods Relevant studies were searched from databases including CNKI,Wanfang Data,VIP,SinoMed,PubMed,Web of Science,Cochrane Library,Embase and CINAHL,from the inception to 31st January,2024.Data were extracted from the selected literature and a bias assessment tool of risk predictive model was used to evaluate the risk of bias and applicability of the included literature.Results A total of 1,035 articles were retrieved,of which seven studies involving 13 predictive models were finally included after screening.The sample sizes ranged from 305 to 2,669 cases and lung infection rates ranged from 5.40%to 20.02%.The repeatedly reported predictors included age,gender,chronic obstructive pulmonary disease,hypoproteinaemia,American Society of Anesthesiologists(ASA)Physical Status Classification and white blood cell count.In the 13 models constructed,the reported area under the curve(AUC)of subjects'job characteristics ranged from 0.667 to 0.996.Five out of seven studies had good overall applicability,but all with high risk of bias.Conclusion The predictive models for lung infections in elderly patients with hip fracture are still in the stage of development.Although the predictive models show some predictive performance,however they are still deficient,and all studies have been found with a high risk in bias.

Working memory is an executive memory process that includes encoding, maintenance, and retrieval. These processes can be modulated by transcranial alternating current stimulation (tACS) with sinusoidal waves. However, little is known about the impact of the rate of current change on working memory. In this study, we aimed to investigate the effects of two types of tACS with different rates of current change on working memory performance and brain activity. We applied a randomized, single-blind design and divided 81 young participants who received triangular wave tACS, sinusoidal wave tACS, or sham stimulation into three groups. Participants performed n-back tasks, and electroencephalograms were recorded before, during, and after active or sham stimulation. Compared to the baseline, working memory performance (accuracy and response time) improved after stimulation under all stimulation conditions. According to drift-diffusion model analysis, triangular wave tACS significantly increased the efficiency of non-target information processing. In addition, compared with sham conditions, triangular wave tACS reduced alpha power oscillations in the occipital lobe throughout the encoding period, while sinusoidal wave tACS increased theta power in the central frontal region only during the later encoding period. The brain network connectivity results showed that triangular wave tACS improved the clustering coefficient, local efficiency, and node degree intensity in the early encoding stage, and these parameters were positively correlated with the non-target drift rate and decision starting point. Our findings on how tACS modulates working memory indicate that triangular wave tACS significantly enhances brain network connectivity during the early encoding stage, demonstrating an improvement in the efficiency of working memory processing. In contrast, sinusoidal wave tACS increased the theta power during the later encoding stage, suggesting its potential critical role in late-stage information processing. These findings provide valuable insights into the potential mechanisms by which tACS modulates working memory.
