The volume of gynecological and obstetric surgeries is large,and the high rates of adverse events incidence such as perioperative cycle fluctuations,postoperative nausea and vomiting and adverse emotional experiences,which is a concern for clinicians.Esketamine is a right-handed isomer of ketamine with a strong affinity for the N-methyl-D-aspartate receptor(NMDAR),which has a rapid anesthetic,analgesic and antidepressant effect.It can be administered through multiple routes and has been widely used in clinical anesthesia,postoperative analgesia and depression treatment.The application of esketamine injection in clinical practice is still relatively short,and the benefits and mechanisms during perioperative application have not been fully elucidated,making it a research hotspot in recent years.Many studies have reported that the application of esketamine injection in obstetrics and gynecology surgery can stabilize circulation,and reduce respiratory depression,nausea and vomiting and other adverse reactions.It is also beneficial for the prevention and treatment of postpartum depression under certain conditions,but sometimes there are also temporary pseudo-psychiatric symptoms and other adverse reactions.In this article,we review the pharmacological effects,perioperative application and impact on postoperative recovery of esketamine based on the specialty characteristics of obstetrics and gynecology surgery,and clarify its current application status,as well as possible clinical applications and research directions in the future,to provide reference for the clinicians.

Background::There is a need for effective and safe therapies for psoriasis that provide sustained benefits. The aim of this study was to assess the efficacy and safety of tildrakizumab, an anti-interleukin-23p19 monoclonal antibody, for treating moderate-to-severe plaque psoriasis in Chinese patients.Methods::In this multi-center, double-blind, phase III trial, patients with moderate-to-severe plaque psoriasis were enrolled and randomly assigned (1:1) to receive subcutaneous tildrakizumab 100 mg or placebo at weeks 0 and 4. Patients initially assigned to placebo were switched to receive tildrakizumab at weeks 12, 16, and every 12 weeks thereafter. Patients in the tildrakizumab group continued with tildrakizumab at week 16, and every 12 weeks until week 52. The primary endpoint was the Psoriasis Area and Severity Index (PASI 75) response rate at week 12.Results::At week 12, tildrakizumab demonstrated significantly higher PASI 75 response rates (66.4% [73/110] vs. 12.7% [14/110]; difference, 51.4% [95% confidence interval (CI), 40.72, 62.13]; P <0.001) and Physician’s Global Assessment (60.9% [67/110] vs. 10.0% [11/110]; difference, 49.1% [95% CI, 38.64, 59.62]; P <0.001) compared to placebo. PASI 75 response continued to improve over time in both tildrakizumab and placebo-switching to tildrakizumab groups, reaching maximal efficacy after 28 weeks (86.8% [92/106] vs. 82.4% [89/108]) and maintained up to 52 weeks (91.3% [95/104] vs. 87.4% [90/103]). Most treatment-emergent adverse events were mild and not related to tildrakizumab. Conclusion::Tildrakizumab demonstrated durable efficacy through week 52 and was well tolerated in Chinese patients with moderate-to-severe plaque psoriasis.Trial registration::ClinicalTrials.gov, NCT05108766.

Background::Limited information exists regarding the impact of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection on psoriasis patients. The objective of this study was to identify clinical factors associated with the prognosis of psoriasis following SARS-CoV-2 infection.Methods::A retrospective, multicenter study was conducted between March and May 2023. Univariable and multivariable logistic regression analyses were employed to identify factors associated with coronavirus disease 2019 (COVID-19)-related psoriasis outcomes. The study included 2371 psoriasis patients from 12 clinical centers, with 2049 of them having been infected with SARS-CoV-2.Results::Among the infected groups, lower exacerbation rates were observed in individuals treated with biologics compared to those receiving traditional systemic or nonsystemic treatments (22.3% [236/1058] vs. 39.8% [92/231] vs. 37.5% [140/373], P <0.001). Psoriasis progression with lesions (adjusted odds ratio [OR] = 8.197, 95% confidence interval [95% CI] = 5.685–11.820, compared to no lesions), hypertension (adjusted OR = 1.582, 95% CI = 1.068–2.343), traditional systemic (adjusted OR = 1.887, 95% CI= 1.263–2.818), and nonsystemic treatment (adjusted OR= 1.602, 95% CI= 1.117–2.297) were found to be associated with exacerbation of psoriasis after SARS-CoV-2 infection, but not biologics (adjusted OR = 0.931, 95% CI = 0.680–1.274, compared to no treatment), according to multivariable logistic regression analysis. Conclusions::A reduced risk of psoriasis exacerbation after SARS-CoV-2 infection was observed with biologics compared to traditional systemic and nonsystemic treatments. Significant risk factors for exacerbation after infection were identified as existing psoriatic lesions and hypertension.

Objective:To explore the risk factors of osteosarcopenia in maintenance hemodialysis patients, construct a diagnostic nomogram model and verify the effect.Methods:Usingthe convenient sampling method, a total of 697 patients who underwent regular hemodialysis in six hospitals in Shanghai from July 2020 to April 2021 were selected as the modeling set, and 132 patients who underwent regular hemodialysis in Tongji Hospital in Shanghai in November 2020 were selected as the validation set. General information, laboratory indicators, human parameters, physical functions, nutritional status, physical activity, cognitive function, and depression were collected. Logistic regression was used to analyze the risk factors of osteosarcopenia in maintenance hemodialysis patients and to construct a nomogram model. The effect of the model was evaluated by the area under the receiver operating characteristic curve, calibration curve, and decision curve.Results:A total of 697 maintenance hemodialysis patients were included in the modeling set, including 171 patients with osteosarcopenia, with an incidence rate of 24.53% (171/697). The results of the binomial logistic regression analysis showed that age, body mass index, physical activity intensity, and Charlson Comorbidity Index (CCI) were the influencing factors for the occurrence of osteosarcopenia in maintenance hemodialysis patients ( P<0.05). The area under the receiver operating characteristic curve in the modeling set, ten-fold cross-validation, and validation set were 0.835, 0.827, and 0.851, respectively. The calibration curves of the modeling and validation sets fitted well. The decision curve showed that the clinical utility of the nomogram was good. Conclusions:Maintenance hemodialysis patients are prone to osteosarcopenia. Old age, low body mass index, high Charlson Comorbidity Index, and low-intensity physical activity are risk factors for osteosarcopenia in maintenance hemodialysis patients. A nomogramdiagnostic model based on the above-mentioned influencing factors can help medical staff identify high-risk populations early and develop prevention and treatment measures.

Objective To systematically evaluate and analyze the qualitative research on the experience of maintenance hemodialysis patients,so as to provide references for the implementation of exercise interventions in maintenance hemodialysis patients.Methods We searched databases including PubMed,Embase,Web of Science,Cochrane Library,PsycINFO,CINAHL,CBM,CNKI,WanFang Database and VIP from inception to September 30,2022,to collect qualitative studies about exercise experience of maintenance hemodialysis patients.The quality of included studies was evaluated according to JBI Critical Appraisal Tool for qualitative studies in Australia.The results were integrated by integrating methods.Results A total of 14 studies were included.47 completed findings were grouped according to their similarities to form 12 categories.These categories resulted in 4 synthesized findings.Integration results 1:recognizing the positive effects and potential risks of intradialytic exercise.Integration results 2:barriers and facilitators of intradialytic exercise.Integration results 3:needs of intradialytic exercise.Integration results 4:exercise experience on non-dialysis day.Conclusion The experience and needs of maintenance hemodialysis patients should be considered to ensure patient compliance and continuity when exercise programs were designed.

Objective:To explore the relationship between insomnia and osteoporosis.Methods:Mendelian randomization (MR) analysis were used in this study. The single nucleotide polymorphisms (SNPs) related to insomnia from genome-wide association analysis research data were selected as the instrumental variables by using inverse variance weighted (IVW), MR-Egger regression, weighted median method, maximum likelihood, penalized weighted median estimator, and Mendelian randomization robust adjusted profile score (MR-RAPS) to determine the causal relationship between insomnia and osteoporosis. Odds ratio ( OR) and 95% confidence interval ( CI) values were used to evaluate the association between insomnia and osteoporosis. Cochran′s Q-test was used to detect heterogeneity of SNPs, MR-Egger regression was used to test for level pleiotropy, and the leave-one-out method was used to test sensitivity, MR pleiotropy residual sum and outlier (MR-PRESSO) method and radial MR were used to detect erroneous outliers. Results:The screening criteria were set based on the three major assumptions of MR; finally, 31 SNPs were included in the MR analysis. The results of MR causal effect analysis using the IVW method showed that insomnia increased the risk of osteoporosis by about 0.7% ( OR=1.007, 95% CI 1.001-1.014, P=0.044); heterogeneity testing showed heterogeneity between SNPs ( Q=57.91, P<0.001); and the MR- Egger intercept test did not indicate horizontal pleiotropy in this study (intercept value=3.807×10 -5, P=0.888). Leave-one-out method showed that no single SNP had a significant impact on the overall results. No abnormal SNP was detected according to the MR-PRESSO results ( P=0.059), and radial MR did not detect any outliers. Conclusion:Mendelian randomization analysis showed that insomnia can increase the risk of osteoporosis.

Objective:To investigate the neuropsychological and imaging features of patients with posterior cortical atrophy (PCA).Methods:Patients of PCA, dementia with Lewy bodies (DLB), typical Alzheimer′s disease (t-AD) who were diagnosed in the Department of Neurology, Huashan Hospital, Fudan University from September 27, 2019, to September 24, 2021 were enrolled, and the normal controls who visited the Outpatient and Physical Examination Centers of Huashan Hospital, Fudan University and Rizhao People′s Hospital at the same time were enrolled, too. Neuropsychological assessments, magnetic resonance imaging (MRI), and positron emission tomography (PET)/CT data of the 4-group subjects were collected. Variance analysis was used to compare the differences in neuropsychological performance among the 4 groups, and the imaging features of PCA patients were summarized.Results:Eleven PCA patients, 17 DLB patients, 31 t-AD patients, and 11 normal controls were included in the study. The cognitive function of patients in the PCA group [Mini-Mental State Examination (MMSE) score 13.52±1.81; Montreal Cognitive Assessment (MoCA) score 7.06±1.72] was significantly impaired compared to the normal control group (MMSE score 27.85±1.75, t=-6.561, P<0.001; MoCA score 23.60±1.59, t=-7.968, P<0.001]. However, there was no statistically significant difference compared to the DLB group and the t-AD group. Patients in the PCA group exhibited more severe impairments in attention, executive function, and language compared to the DLB group (Trail Making Test A score: 298.86±16.16 vs 110.07±18.62, t=9.980, P<0.001; Trail Making Test B score: 305.51±18.89 vs 230.34±23.59, t=2.865, P=0.024; Boston Naming Test score: 8.67±1.53 vs 15.66±1.56, t=-2.682, P=0.013) and the t-AD group (148.91±12.77, t=7.071, P<0.001; 200.78±19.34, t=3.789, P=0.004; 15.15±1.05, t=-2.544, P=0.016). Scores for visuospatial function [PCA group: 1(0, 1), normal control group: 3(3, 3), Z=-4.023, P<0.001] and visual perception [PCA group: 0(0, 1), normal control group: 35(34, 36), Z=-3.704, P<0.001] were significantly lower in the PCA group compared to the normal control group. The cranial MRI findings of PCA patients showed atrophy of the parietal and occipital lobes, with less obvious atrophy of the medial temporal lobe, which can be distinguished from t-AD. 18F-fluorodeoxyglucose PET/CT of the PCA patients showed a relative reduced glucose metabolism in the bilateral parietal lobe, occipital lobe and posterior cingulate gyrus, while the 18F-florbetapir PET/CT showed deposition of amyloid protein in the bilateral frontal lobe, parietal lobe, temporal lobe, and cingulate gyrus. Conclusions:PCA patients exhibit neuropsychological characteristics of visuospatial dysfunction, along with impairments in various cognitive domains such as memory, attention, and executive functions. The typical MRI feature is parietal occipital lobe atrophy, and the PET/CT findings are consistent with metabolic changes in AD.

Objective:To explore the remodeling of brain function 2 years after anterior cruciate ligament reconstruction (ACLR) and its relationship with functioning and behavior.Methods:Forty-eight volunteers who had received ACLR from the same surgeon were divided into a coping and a non-coping group, each of 17. Another 14 health volunteers formed the control group. Resting-state functional magnetic resonance imaging was used to record blood oxygen level-dependent signals from the members of all three groups in the 0.01 to 0.08Hz band. One-way analysis of variance was applied to the differences in low frequency amplitude (ALFF) observed.Results:The results of multiple comparisons with Gaussian random field theory correction showed that the differences in bilateral putamen ALFF values among the three groups were statistically significant. The signals from the right cerebellar area 8 and the bilateral putamen were significantly stronger among the non-coping group on average. Pearson correlation analysis showed that the ALFF values from the right cerebellar 8 region were positively and significantly more correlated with the symmetry of a subject′s Y balance function test results in the coping group compared with the non-coping group.Conclusions:Subcortical brain function remodeling occurs in ACLR patients returning to exercise after surgery, and a Y-balance function test can indirectly reflect such remodeling. That can provide a basis for designing programs for rehabilitating advanced brain functions.

Objective:To evaluate the value of left echography (LVO) in the diagnosis of false ventricular aneurysm complicated with mural thrombus.Methods:The clinical data of 10 patients with suspected pseudoventricular aneurysm examined by thoracic echocardiography (TTE) in Wuhan Asian Heart Hospital from January 2018 to March 2024 were retrospectively analyzed. All patients underwent LVO examination to further diagnose pseudoventricular tumor and whether it was complicated with mural thrombosis. Computed tomography angiography (CTA) or cardiac magnetic resonance (CMR) examination was used as the gold standard to analyze the diagnostic value of LVO in the diagnosis of pseudoventricular tumor.Results:Among the 10 suspected pseudoventricular tumors examined by TTE, LVO detected 6 cases of left ventricular pseudoaneurysm and 1 case of right ventricular pseudoaneurysm; CTA confirmed that 6 cases of left ventricular pseudoaneurysm detected by LVO were correctly diagnosed, 1 case of right ventricular pseudoaneurysm was misdiagnosed, CMR diagnosed right ventricular diverticula, LVO diagnosis accuracy was 6/7, and 4 cases of thrombi were detected. The detection rate was 4/4. The maximum transverse diameter of the tumor body of the communicating mouth/false ventricular aneurysm was 0.46±0.04. 1 patient underwent coronary artery bypass grafting and resection of false ventricular aneurysm. 1 patient underwent coronary artery interventional stent surgery; 4 routine conservative drug treatment, follow-up observation; One case of right ventricular diverticulum did not require special treatment.Conclusions:LVO contrast agent can clearly show the tumor body and location, measure the tumor entrance and size, and show mural thrombus. It is the first choice for the identification of false ventricular tumor. The diverticula was similar to the image of false ventricular aneurysm, and the sensitivity and specificity of right ventricular wall motion were higher in CMR than in LVO.

Fulminant myocarditis occurs suddenly and progresses rapidly, often leading to severe heart failure, hypotension, or cardiogenic shock. Widespread myocardial calcification secondary to fulminant myocarditis is clinically rare, with sporadic reports both domestically and internationally. This article reports a case of a young female patient who presented with acute onset and rapidly deteriorating condition, with imaging indicating myocardial calcification by the second day of hospitalization, highlighting the unusual speed of progression.
