[The association between cortical venous outflow and futile recanalization in patients with acute ischemic stroke due to large vessel occlusion in the anterior circulation].

Objective: To explore the association of baseline venous outflow (VO) profile with futile recanalization in patients with acute ischemic stroke due to large vessel occlusion in the anterior circulation. Methods: The clinical and imaging data of patients presented with large vessel occlusion in the anterior circulation and underwent emergency endovascular treatment at Huashan Hospital from March 2015 to December 2021 were retrospectively included in the study. All patients were assessed by the National Institutes of Health Stroke Scale (NIHSS) at baseline.Baseline VO profile was determined by a 0-6 semi-quantitative scoring system which assessed opacification of the ipsilateral superficial middle cerebral vein, vein of Labbé and vein of Trolard on single-phase CT angiography (CTA) images. A 90-day telephone follow-up was performed and functional outcome was evaluated by 90 d modified Rankin scale (mRS). Successful recanalization of the occluded artery, defined as final modified Thrombolysis in Cerebral Infarction scale (mTICI) 2b-3, was considered to be futile if patients failed to achieve functional independence (90 d mRS 0-2). Univariate analysis and receiver operating characteristic (ROC) curve analysis were used to explore the optimal cutoff predicting functional indendence. The associations between cortical VO in ischemic area and futile recanalization were evaluated using binary logistic regression analysis and backward linear regression based on Akaike information criterion (AIC). Results: A total of 150 patients met the inclusion criteria, with 92 males (61.3%) and 58 females (38.7%). The median age [M(Q1, Q3)]was 71 (61, 78) years and the median baseline National Institute of Health Stroke Scale (NIHSS) score [M(Q1, Q3)]was 15 (11, 18). Univariate logistic regression analysis showed that baseline VO was associated with 90-day functional independence (OR=1.587, 95%CI: 1.185-2.1873). After classifying VO into two categories based on the receiver operating characteristic (ROC) curve, VO≥4 showed an independent association with functional independence (OR=5.133, 95%CI: 1.530-9.361) after adjusting for age, baseline glucose, NIHSS score, baseline infarct core volume, modified Tan (mTan) score, hypoperfusion intensity ratio (HIR), etiological classification, recanalization, presence of any hemorrhagic transformation and final infarct volume. Futile recanalization was observed in 44 (48.4%) of the 91 patients who achieved successful recanalization. Stepwise logistic regression revealed that VO≥4 was an independent protective factor for futile recanalization (OR=0.234, 95%CI: 0.054-0.878). Moreover, in patients with mTICI 2c-3, VO≥4 showed a stronger association with futile recanalization (OR=0.018, 95%CI: 0-0.255). Conclusion: A favorable VO profile at onset protects against futile recanalization in patients with large vessel occlusion in the anterior circulation, and provides a simple and feasible auxiliary method for predicting the prognosis of endovascular therapy in such patients.

Nirmatrelvir increases blood tacrolimus concentration in COVID-19 patients as determined by UHPLC-MS/MS method.

OBJECTIVE: Transplant recipients have a higher risk of SARS-CoV-2 infection owing to the use of immunosuppressive drugs like tacrolimus (FK506). FK506 and nirmatrelvir (NMV) (an anti-SARS-CoV-2 drug) are metabolized by cytochrome P450 3A4 and may have potential drug-drug interactions. It is important to determine the effect of NMV on FK506 concentrations. PATIENTS AND METHODS: Following protein precipitation from blood, FK506 and its internal standard (FK506-13C,2d4) were detected by ultra-high performance liquid chromatography/tandem mass spectrometry (UHPLC-MS/MS). Total 22 blood samples (valley concentrations) from two coronavirus disease 2019 (COVID-19) patients were collected and analyzed for FK506 concentrations. RESULTS: Blood levels of FK506 (0.5-100 ng/mL) showed good linearity. The UHPLC-MS/MS method was validated with intra- and inter-batch accuracies of 104.55-107.85%, and 99.52-108.01%, respectively, and precisions of < 15%. Mean blood FK506 concentration was 12.01 ng/mL (range, 3.15-33.1 ng/mL). Five-day co-administration with NMV increased the FK506 concentrations from 3.15 ng/mL to 33.1 ng/mL, returning to 3.36 ng/mL after a 9-day-washout. CONCLUSIONS: We developed a simple quantification method for therapeutic drug monitoring of FK506 in patients with COVID-19 using UHPLC-MS/MS with protein precipitation. We found that NMV increased FK506 blood concentration 10-fold. Therefore, it is necessary to re-consider co-administration of FK506 with NMV.

[A retrospective analysis of clinical characteristics and prognostic factors for 152 cases of Staphylococcus aureus bloodstream infection].

To understand the clinical characteristics of Staphylococcus aureus bloodstream infection and the main risk factors affecting clinical prognosis, providing a reference for clinical prevention and control of Staphylococcus aureus bloodstream infection. In this study, the clinical data of 152 patients with Staphylococcus aureus bloodstream infection admitted to Guangdong Provincial People's Hospital from January 2019 to December 2021 were retrospectively analyzed by reviewing the electronic medical record system, including underlying diseases, clinical characteristics, risk factors, and bacterial resistance. Statistical methods such as Chi-Squared Test and t Test were used to analyze the related risk factors that may affect the clinical characteristics and prognosis of patients with Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infection, then the variables with P<0.05 in univariate analysis were included in the multivariate logistic regression model to analyze the independent risk factors of poor prognosis. The results showed among 152 patients with Staphylococcus aureus bloodstream infection, 50 patients (32.89%) were infected with MRSA. In comparison, 102 patients (67.11%) were infected with methicillin-sensitive Staphylococcus aureus (MSSA). Except for rifampicin, the resistance rate of MRSA to commonly used antibiotics was all higher than that of MSSA, and the difference was statistically significant (Chi-square values were 8.272, 11.972, 4.998, 4.776, respectively;all P-values are less than 0.05). Strains resistant to vancomycin, linezolid, and quinupristin/dalfopristin were not found. In the MRSA group, indwelling catheter and drainage tube, carbapenems, and ß-lactamase inhibitor treatment were significantly higher than the MSSA group. The difference was statistically significant (P<0.05). The incidence of poor prognosis of bloodstream infection in the MRSA group was higher than that in the MSSA group (34.00% vs 13.73%), and the difference was statistically significant (χ2=8.495, P<0.05). No independent risk factors associated with poor prognosis were found in the included patients with MRSA bloodstream infection.Multivariate Logistic regression model analysis showed that solid malignant tumors (OR=13.576, 95%CI: 3.352-54.977, P<0.05), mechanical ventilation (OR=7.468, 95%CI: 1.398-39.884, P<0.05) were the most important independent risk factors for poor prognosis in patients with Staphylococcus aureus bloodstream infection. In summary, the poor prognosis rate of MRSA bloodstream infection is higher than that of MSSA. The clinical evaluation of related risk factors should be strengthened, targeted prevention and control interventions should be taken to improve the prognosis of patients with Staphylococcus aureus bloodstream infection, and the use of antibiotics should be rational and standardized, to control bacterial infection and drug resistance effectively.

[Associations of circulating leptin levels with colorectal adenoma and colorectal cancer: a case-control and Mendelian randomization study].

OBJECTIVE: To explore the causal association between circulating leptin levels and the risk of colorectal adenoma and colorectal cancer. METHODS: We collected demographic and clinical data and serum samples from 497 patients with colorectal adenoma, 955 patients with colorectal cancer, and 911 healthy individuals from the First Affiliated Hospital of Zhejiang University School of Medicine, Zhejiang Cancer Hospital, Zhuji People's Hospital, and Lin'an District First People's Hospital. Instrumental variables of leptin were selected and genotyping tests were performed. A logistic regression model and stratified analysis were used to evaluate the association of serum leptin levels with colorectal adenoma, colorectal cancer, and the progression of colorectal adenoma to colorectal cancer. Genetic risk score (GRS) and single nucleotide polymorphisms (SNPs) were further used as instrumental variables in one-sample and two-sample Mendelian randomization analyses leveraging two-stage least squares and inverse-variance weighted methods to estimate the causal association of leptin levels with the risk of colorectal adenoma, colorectal cancer, and progression of colorectal adenoma to colorectal cancer. RESULTS: High levels of leptin, compared with its lowest quartile, were positively correlated with colorectal adenoma (P=0.005) and negatively with colorectal cancer (P < 0.001) and the risk of progression of colorectal adenoma to colorectal cancer (P < 0.001). Mendelian randomization analysis showed that GRS of leptin, either weighted or not, was not significantly correlated with the risk of colorectal adenoma, colorectal cancer, or the progression of colorectal adenoma to colorectal cancer, nor did the two-sample Mendelian randomization study support an association between leptin and the risk of colorectal cancer (P>0.05). CONCLUSION: Although the case-control study suggests probable correlations of leptin with the risk of colorectal adenoma, colorectal cancer, and colorectal adenoma progression to colorectal cancer, Mendelian randomization studies did not support a causal association of leptin with the risks of colorectal adenoma, colorectal cancer, or colorectal adenoma progression to colorectal cancer.

[Analysis of liver function injury associated with 2019-nCoV Omicron mutant strains].

Objective: To investigate the clinical features and influencing factors of liver function injury in patients with 2019-nCoV/SARS-CoV-2 Omicron mutant strains. Methods: 1 183 confirmed imported cases of SARS-CoV-2 who were admitted at Shanghai Public Health Clinical Center (affiliated to Fudan University) from July 1, 2021 to January 15, 2022 were collected. Clinical data, viral genotyping and laboratory test results were collected to retrospectively analyze the basic condition and clinical characteristics of liver function injury. Statistical analysis was performed using t-test or Wilcoxon rank-sum test, χ2 test or Fisher's exact test, Pearson correlation test and logistic regression analysis. Results: 125 (10.6%) cases had raised baseline ALT level and 60 (5.1%) cases had abnormal baseline AST level. Among them, 33 cases (2.8%) had received hepatoprotective drugs. Liver function injury was generally mild in SARS-CoV-2 infection and minimal in Omicron mutant strains. Leukocyte count was increased in patients with raised alanine aminotransferase (ALT) [(6.96±1.78)×109/L vs. (6.41±1.96)×109/L, P=0.005 2], CT scan showed the proportion of liver hypodensity was significantly increased (2.4% vs. 0.3%, P=0.018 0). High-sensitivity C-reactive protein [(7.83±22.36) mg/L vs. (2.68±6.21) mg/L, P=0.007 8] and D-dimer [(0.34±0.39) µg/ml vs. (0.31±0.75) µg/ml, P=0.047 5] levels were higher in patients with raised AST than normal group. 26 cases had normal liver function at hospital admission; however, abnormal liver function was occurred during the course of the disease. Another 8 patients had abnormal liver function at hospital admission, and reduced liver function further during the course of treatment. Recovery time and length of hospital stay was significantly affected in patients with worsened liver function. Baseline body mass index value [odds ratio (OR)]=1.80, P=0.047), non-Omicron strains (OR=12.63, P=0.046), D-dimer (OR=2.36, P=0.047) and interleukin-6 levels (OR=1.03, P=0.009), and those who used glucocorticoids and/or ulinastatin after hospital admission (OR=6.89, P=0.034) had a higher risk of worsening liver function. Conclusions: Liver dysfunction could be observed among COVID-19 patients. Patients infected with omicron variant generally showed mild liver injury. Dynamic monitoring of liver function is necessary, especially among those with baseline elevated IL-6, D-Dimer level and use of antiinflammation medication during treatment.

[Evaluation of safety and immunogenicity of hepatitis E vaccine in maintenance hemodialysis patients].

Objective: To evaluate the safety and immunogenicity of hepatitis E vaccine(HEV)in Maintenance hemodialysis(MHD)patients. Methods: Based on an open-labeled controlled trial, from May 2016 to March 2018, 35 eligible MHD patients were recruited in the Hemodialysis Center of Zhongshan Hospital Affiliated to Xiamen University as the experimental group, and 70 MHD patients with matched age, gender and underlying diseases as the control group. The experimental group received HEV at 0, 1 and 6 months according to the standard vaccination procedures, while the control group received routine diagnosis and treatment without vaccine and placebo injection to observe the safety and immunogenicity of the vaccine. The safety of vaccine in MHD population was evaluated by the incidence of adverse reactions/events in the experimental and control groups. The immunogenicity of HEV in MHD patients was evaluated by comparing the data from the phase Ⅲ clinical trial. Results: The overall incidence of adverse reactions/events was 17.1% (18/105), and there were no grade 3-4 adverse reactions/events related to vaccination. In the experimental group, the incidence of local adverse reactions/events was 20.0% (7/35), and the incidence of systemic adverse reactions/events was 17.1% (6/35).There was no significant difference in the incidence of systemic adverse reactions/events between the experimental group and the control group (P>0.05). There were 23 patients receiving 3 doses with the standard schedule. The positive rate of HEV-IgG antibody was 100% and the GMC was 14.47(95%CI:13.14-15.80) WU/ml, which showed no significant difference compared with the 46 patients in Phase Ⅲ clinical trial (t=-1.04, P>0.05). Conclusion: Recombinant HEV has good safety and immunogenicity in MHD patients.

Wernekinck Commissure Syndrome with Holmes Tremor: A Report of Two Cases and Review of Literature.

Wernekinck commissure syndrome is a rare midbrain infarction, it consists of several symptoms including bilateral cerebellar ataxia, ophthalmoplegia, and palatal tremor. Holmes tremor is a rare clinical syndrome characterized by a combination of resting, postural, and action tremors. We describe two cases of Wernekinck commissure syndrome with Holmes tremor. To the best of our knowledge, it has been rarely reported in the literature to date. Both of the cases were presented with acute onset of bilateral cerebellar ataxia, dysarthria, and Holmes tremor. In the treatment, one patient was given "clonazepam and benheisol," the other was received acupuncture therapy, both of them showed a marked improvement in ataxia and tremor.

Gynecologic Survivorship Tool: Development, Implementation, and Symptom Outcomes.

PURPOSE: To describe the development and implementation of a new digital health clinical tool (Gynecologic Survivorship Tool [GST]) for symptom management of women surgically treated for gynecologic cancer; to assess its feasibility; and to conduct a retrospective review of the data. MATERIALS AND METHODS: The GST was developed on the basis of a comprehensive review of the literature, multidisciplinary expert opinion, and feedback from women with a history of gynecologic cancer. It is composed of 17 questions addressing six main categories-gynecologic health (abnormal bleeding/pain), lymphedema, vaginal/vulvar dryness, sexual health, menopause (hot flushes/sleep difficulties), and bowel/urinary issues. An electronic version using the Memorial Sloan Kettering Cancer Center Engage platform was piloted in two clinics for patients with endometrial or cervical cancer. Health information was generated into clinical summaries and identified concerns for actionable response. Associations of symptom and survey time point were assessed by longitudinal models using generalized estimating equations. RESULTS: From January 1, 2019, to February 29, 2020, 3,357 GST assessments were assigned to 1,405 patients, with a 71% completion rate (90% within 5 minutes). Sixty-eight percent were performed at home via a patient portal, 32% at follow-ups using a clinic iPad. The most common symptoms were bowel problems, swelling/fluid, pain during examination, vaginal or vulvar dryness, and vaginal bleeding. Implementation challenges included improving patient compliance and ensuring that reports were reviewed by all clinical teams. We developed screening e-mails detailing patients whose assessments were due, planned training sessions for multidisciplinary teams, and incorporated feedback on methods for reviewing symptoms reports. CONCLUSION: The GST demonstrated feasibility, a high completion rate, and minimal time commitment. It was an effective electronic reporting mechanism for patients, enabling the medical team to develop specific strategies for alleviating bothersome symptoms during follow-up.

[Clinical features of young inpatients with angle-closure glaucoma].

Objective: To analyze the composition of diagnosis in young inpatients with angle-closure glaucoma and to compare the clinical characteristics between primary angle-closure glaucoma (PACG) and secondary angle-closure glaucoma (SACG). Methods: This was a retrospective case series study. Angle-closure glaucoma patients aged 40 years or younger and hospitalized in Zhongshan Ophthalmic Center from January 2012 to December 2019 were included. The clinical diagnosis, gender, onset age, and results of general ophthalmic examination, A-scan ultrasonography measurements, ultrasound biomicroscopy, optical coherence tomography and visual field were recorded. The proportions and composition of PACG and SACG, as well as the misdiagnosis ratio, were analyzed. The onset age, visual acuity, visual field, and ocular parameters were compared between patients with PACG and SACG. Non-normally distributed data were represented by M (Q1, Q3). The difference between groups were compared by Mann-Whitney U test, Chi square test, and independent sample t test. Results: A total of 243 patients (243 eyes) were included in this study. The mean onset age was (28±9) years, and the male-to-female ratio was 1∶1.79. There were 93 patients (38.3%) in PACG group and 150 (61.7%) in SACG group. The age of PACG [34(28, 38)] was older than that of SACG [28(19, 34)], and the proportion of males in the SACG group (44.0%, 66/150) was significantly higher than that in the PACG group (22.6%, 21/93) (Z=-5.34, χ2=11.46; both P<0.01). Nanophthalmos (22.7%, 34 cases), autosomal recessive bestrophinopathy (ARB) (19.3%, 29 cases), uveitis (18.7%, 28 cases) and retinitis pigmentosa (14.0%, 21 cases) were the most common causes of SACG. The best corrected visual acuity (logarithm of the minimum angle of resolution) was 0.10 (0.00, 0.48) and 0.40 (0.06, 1.00), mean deviation of visual field was -8.07 (-27.49, -2.09) and -15.04 (-28.75, -5.97) dB, and subfoveal choroidal thickness was (452.3±130.7) and (396.3±120.9) µm in the PACG and SACG groups, respectively. The differences were statistically significant (Z=-4.86, -2.14; t=2.37; all P<0.05). There was no statistical difference in intraocular pressure, cup-to-disc ratio, extent of peripheral anterior synechia, central anterior chamber depth, lens thickness, mean retinal nerve fiber layer thickness between these two groups (all P>0.05). The misdiagnosis ratio was 10.7% (26/243) in all patients, while the misdiagnosis ratio of the SACG group (16.7%, 25/150) was higher than that of the PACG group (1.1%, 1/93) (χ²=14.61, P<0.001). Conclusions: PACG, nanophthalmos and ARB are the most common etiologies in young inpatients with angle-closure glaucoma. Compared to PACG, patients with SACG are younger, with worse visual acuity and more severe visual field defects, and easier to be misdiagnosed.

Trends in oligomannosylation and α1,2-mannosidase expression in human cancers.

Aberrant protein glycosylation is a prominent cancer feature. While many tumour-associated glycoepitopes have been reported, advances in glycoanalytics continue to uncover new associations between glycosylation and cancer. Guided by a comprehensive literature survey suggesting that oligomannosylation (Man5-9 GlcNAc2) is a widespread and often regulated glycosignature in human cancers, we here revisit a valuable compilation of nearly 500 porous graphitized carbon LC-MS/MS N-glycomics datasets acquired across 11 human cancer types to systematically test for oligomannose-cancer associations. Firstly, the quantitative glycomics data obtained across 34 cancerous cell lines demonstrated that oligomannosylation is a pan-cancer feature spanning in a wide abundance range. In keeping with literature, our quantitative glycomics data of tumour and matching control tissues and new MALDI-MS imaging data of tissue microarrays showed a strong cancer-associated elevation of oligomannosylation in both basal cell (p = 1.78 × 10-12) and squamous cell (p = 1.23 × 10-11) skin cancer and colorectal cancer (p = 8.0 × 10-4). The glycomics data also indicated that some cancer types including gastric and liver cancer exhibit unchanged or reduced oligomannose levels, observations also supported by literature and MALDI-MS imaging data. Finally, expression data from public cancer repositories indicated that several α1,2-mannosidases are regulated in tumour tissues suggesting that these glycan-processing enzymes may contribute to the cancer-associated modulation of oligomannosylation. This omics-centric study has compiled robust glycomics and enzyme expression data revealing interesting molecular trends that open avenues to better understand the role of oligomannosylation in human cancers.

Concentrations and Related Health Risk Assessment of Pesticides, Phthalates, and Heavy Metals in Strawberries from Shanghai, China.

ABSTRACT: In the present study, a risk assessment of pesticides, phthalates, and heavy metals in strawberries (n = 335) in recent years was conducted by determining the estimated daily intake, target hazard quotient, and hazard index. The study used 128 pesticides, 18 phthalates, and three heavy metals in this determination. It detected 51 pesticide residues in the strawberry samples, and 97.91% samples had levels of at least 1 of the 51 pesticides above the limit of detection. In addition, 2.39% of samples had pesticides higher than the Chinese maximum residue limit. Multiple pesticide residues were detected in most samples. Bis-2-ethylhexyl phthalate, diisobutyl phthalate, and dibutyl phthalate were detected in the strawberry samples, with a high frequency of detection. Their detectable rates were 100, 100, and 89.9%, respectively. In most samples, lead, cadmium, and nickel were detected, with detectable rates 75.76, 92.93, and 92.93%, respectively. The estimated daily intake of analyzed pesticide, phthalate, and heavy metal residues appears to be relatively low compared with the acceptable daily intake. The average target hazard quotients and hazard indices were less than 1. That means that customers who are exposed to the average contaminant levels may not pose a significant health risk. Our results show that the strawberries may be polluted by many kinds of contaminants. Therefore, monitoring of pesticide, phthalate, and heavy metal residues in strawberries should be increasingly developed to fully protect the health of the consumer.

[Histopathological features of squamous cell carcinoma of lung neoadjuvant immunotherapy focusing on responses].

Objective: To analyze the pathologic features of responses to neoadjuvant immunotherapy of squamous cell carcinoma (SCC) of the lung. Methods: The study included 31 patients with resected lung SCC post neoadjuvant immunotherapy. All patients were recruited from the neoadjuvant anti-PD-1 (Sintilimab) phase Ⅰb clinical trial (ChiCTR-OIC-17013726). The histopathological morphology and different degrees of pathologic response to immunotherapy were evaluated basing on irPRC standard. Results: According to the percentage of residual viable tumor (% RVT), pathologic responses of complete pathologic response (cPR), major pathologic response (MPR) and non-MPR were noted in 19% (n=6), 29% (n=9), and 52% (n=16) of patients respectively. In addition, extensive immune activation phenomena (immune cell infiltration, including infiltration of lymphocytes, plasma cells, foamy macrophages, lymphocyte aggregation and tertiary lymphoid structures formation) and tissue repair features (giant cells, granuloma formation, proliferative fibrosis and neovascularization) were observed in tumor regression bed. Conclusions: Neoadjuvant immunotherapy has favorable effect on lung SCC. Pathologic assessment of resected lung cancer specimens after neoadjuvant immunotherapy shows unique histopathological features consistent with its mechanism.

Changes of CaM-CaMK-CREB signaling pathway and related neuron factors in hippocampus of rats after sevoflurane and propofol administration.

OBJECTIVE: To investigate the changes of CaM-CaMK-CREB signaling pathway and related neuron factors in hippocampus of rats after sevoflurane and propofol administration. MATERIALS AND METHODS: A total of 90 SD rats, half male and half female, were selected. They were randomized into anesthesia group (AG) and control group (CG), in which 30 rats under propofol anesthesia in the AG were included in group A, 30 rats under sevoflurane anesthesia were included in group B, and 30 rats under mixed ventilation of air and oxygen were included in the CG. Before (10 rats were killed in each group) and at the end of anesthesia (2 weeks of anesthesia and 7 days of Morris water maze test), rats were respectively killed and then an appropriate amount of hippocampus was separated. Human tumor necrosis factor-alpha (TNF-α), vascular endothelial growth factor (VEGF), calmodulin (CaM), calmodulin-dependent kinase Ⅱ a (CaMK II a), NMDA receptor 2B (NR2B), cysteine aspartate specific protease-3 mRNA (Caspase-3mRNA) and protein contents were detected. RESULTS: The latency of rats in group A and group B, as well as their times of crossing the original platform on 1, 4, and 7d were markedly higher than those of the CG, and those in group B were markedly lower than those in group A (p<0.001). The total distance of rats in group A and group B on 1, 4, and 7d was significantly higher than that of the CG, and that in group B was dramatically lower than that in group A (p<0.001). The speed of rats in the three groups ranged from 1d to 7d, and there was no significant difference at different time points (p>0.05). At the end of anesthesia, the expression levels of CaM mRNA and protein in hippocampus of rats in group A and group B were remarkably higher than those of the CG, and those of CaMK II a mRNA and protein were remarkably lower than those of the CG; the CaM mRNA and protein expression levels in hippocampus of group A were significantly higher than those of group B, and those of CaMK IL a mRNA and protein were significantly lower than those of group B (p<0.001). Simultaneously, the expression levels of NR2BmRNA, Caspase-3mRNA and protein in hippocampus of group A and group B were substantially higher than those of the CG, and those in group B were substantially lower than those in group A (p<0.001). What's more, the TNF-a and VEGF expression levels in hippocampus of group A and B were markedly higher than those of the CG, and those in group B were dramatically lower than those of group A (p<0.001). CONCLUSIONS: Sevoflurane anesthesia on the CaM-CaMK-CREB signaling pathway and learning and memory function of rats is less volatile, which does better in safeguarding stability.

A retrospective cohort study of early mortality among patients with HIV/TB co-infection in Shanghai municipality.

OBJECTIVES: Tuberculosis (TB) is the most common and fatal opportunistic co-infection among HIV-infected individuals. While TB-associated mortality predominantly occurs in the first 90 days after admission, such a correlation remains unclear in HIV/TB co-infected patients. Thus, we aimed to investigate the 90-day mortality and associated risk factors among HIV/TB co-infected patients in China. METHODS: Adult patients with HIV and a newly confirmed TB diagnosis admitted to the Shanghai Public Health Clinical Center between September 2009 and August 2017 were enrolled. Clinical and laboratory characteristics, key treatments and outcomes were collected retrospectively. The associations between different factors and early mortality were analysed. RESULTS: Of the 485 laboratory-confirmed HIV/TB patients [median (range) age = 39 (19-79) years], 413 (85.15%) were male. Diagnosis was confirmed by culture, pathology and acid-fast bacilli smear alone in 362 (74.6%), 6 (1.2%) and 117 (24.1%) patients, respectively. Multiple drug-/rifampin-resistant TB was detected in 21 (5.8%) of the 367 patients with a positive culture. Rifampin or rifabutin was administered to 402 (82.9%) patients. Additionally, 66 (13.6%) and 86 (17.7%) died within 90 days and 1 year of admission, respectively. Of the 64 TB-related deaths, 59 (92.2%) occurred within 90 days of admission. In Cox regression, central nervous system (CNS) TB [odds ratio (OR) = 2.49, 95% confidence interval (CI): 1.46-4.23, P < 0.001], no antiretroviral therapy (ART) within 3 months after admission (OR = 11, 95% CI: 6.4-18.9, P < 0.001), and plasma albumin level < 25 g/L (OR = 1.91, 95% CI: 1.07-3.40, P = 0.021) were associated with early death. CONCLUSIONS: Tuberculosis co-infection was prevalent and fatal in HIV-infected patients, with most deaths occurring within 90 days of admission. Early mortality was associated with CNS-TB, no ART, and serum albumin level < 25 g/L.

[Feasibility and safety of minimally invasive cardiac coronary artery bypass grafting surgery for patients with multivessel coronary artery disease: Early outcome and short-mid-term follow up results].

OBJECTIVE: To explore the feasibility, safety and mid-term outcome of minimally invasive cardiac surgery coronary artery bypass grafting (MICS CABG) surgery. METHODS: Data of patients who underwent MICS CABG between November 2015 and November 2017 in Peking University Third Hospital were retrospectively analyzed. Results were compared with the patients who underwent off-pump coronary aortic bypass grafting (OPCABG) surgery over the same period. The two groups were matched in propensity score matching method according to age, gender, left ventricular ejection fraction, body mass index, severity of coronary artery disease, smoking, diabetes mellitus, hypertension, hyperlipidemia, renal insufficiency, history of cerebrovascular accident, and history of chronic obstructive pulmonary disease (COPD). RESULTS: There were 85 patients in MICS CABG group, including 68 males (80.0%) and 17 females (20%), with an average age of (63.8±8.7) years; 451 patients were enrolled in OPCABG group, and 85 patients were matched by propensity score as control group (OPCABG group). There was no significant difference in general clinical characteristics (P>0.05). The average grafts of MICS CABG and OPCABG were 2.35±0.83 and 2.48±0.72 respectively (P=0.284). No conversion to thoracotomy in MICS CABG group or cardiopulmonary bypass in neither group occurred. There was no significant difference in the major adverse cardiovascular events (MACCEs, 1.17% vs. 3.52%), reoperation (2.34 vs. 3.52%), new-onset atrial fibrillation rate (4.70% vs. 3.52%) or new-onset renal insufficiency rate (1.17% vs. 0%) between MICS CABG group and OPCABG group (P>0.05). The operation time in MICS CABG group was longer than that in OPCABG group [(282.8±55.8) min vs. (246.8±56.9) min, P < 0.05], while the time of ventilator supporting(16.9 h vs. 29.6 h), hospitalization in ICU [(29.3±20.8) h vs. (51.5±48.3) h] and total hospitalization [(18.3±3.2) d vs. (25.7±4.2) d] in MICS CABG group were shorter than those in OPCABG group (P < 0.05). The total patency rate (A+B levels) of MICS CABG was 96.5% after surgery. There was no significant difference in MACCEs rate between the two groups [1.18%(1/85) vs. 3.61%(3/83), P>0.05] in 1-year follow up. CONCLUSION: The MICS CABG surgery is a safe and feasible procedure with good clinical results in early and mid-term follow-up.

Assessment of Ischemic Volumes by Using Relative Filling Time Delay on CTP Source Image in Patients with Acute Stroke with Anterior Circulation Large Vessel Occlusions.

BACKGROUND AND PURPOSE: Thrombectomy up to 24 hours after stroke onset in patients with specific ischemic brain volumes remains a challenge, because many stroke centers do not apply specialized software to calculate ischemic volumes at advanced imaging. We aimed to establish the association between relative filling time delay on CTP source imaging and ischemic volume parameters and the infarct penumbra to core volume mismatch in patients with acute ischemic stroke. MATERIALS AND METHODS: Consecutive patients with acute ischemic stroke and with M1 segment MCA with or without terminal ICA occlusions on baseline CTA and CTP within 24 hours of stroke symptom onset were included. Ischemic volumes were analyzed with software based on CTP maps. Relative filling time delay was classified into 4 grades-grade 0: relative filling time delay = 0 seconds; grade 1: relative filling time delay >0 to ≤4 seconds; grade 2: relative filling time delay >4 to ≤8 seconds; and grade 3: relative filling time delay > 8 seconds. Differences in ischemic volume parameters among relative filling time delay grades were tested. RESULTS: We recruited 138 patients (median age, 69 years; 62.3% male). Different median volumes of the infarct core (grade 0, 7.3 mL; grade 1, 23.3 mL; grade 2, 45.7 mL; grade 3, 135 mL [P < .001]) and the penumbra (grade 0, 47.6 mL; grade 1, 90 mL; grade 2, 110 mL; grade 3, 92 mL [P = .043]) were observed among relative filling time delay grades. Target mismatch (defined by the criteria of the DEFUSE 3 trial) was identified in 71.7% of the patients (99/138). A relative filling time delay grade ≤ 1 independently predicted target mismatch, with a sensitivity of 0.79 (95% CI, 0.7-0.87) and a specificity of 0.66 (95% CI, 0.49-0.8). CONCLUSIONS: Relative filling time delay grade based on CTP source imaging is a simple and effective parameter for evaluating ischemic volumes and target mismatch in patients with acute ischemic stroke. Further studies that compare relative filling time delay grade with clinical functional outcomes are necessary.

[Effects of angiotensin converting enzyme inhibitor/angiotensin receptor blocker on clinical characteristics of coronavirus disease 2019 patients with hypertension].

Objective: To analyze the effects of angiotensin converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) on coronavirus disease 2019 (COVID-19) patients with hypertension, and to provide an evidence for selecting antihypertensive drugs in those patients. Methods: Clinical data were retrospectively analyzed in 58 COVID-19 patients with hypertension admitted to Shanghai Public Health Clinical Center from January 20 to February 22, 2020, including epidemiological history, clinical manifestations, laboratory findings, chest CT and outcome. Patients were divided into ACEI/ARB group and non-ACEI/ARB group. Results: Twenty-six patients were in ACEI/ARB group and the other 32 patients in non-ACEI/ARB group, with median age 64.0 (49.5, 72.0) years and 64.0 (57.0, 68.8) years respectively. The median time to onset was 5(3, 8) days in ACEI/ARB group and 4 (3, 7) days in non-ACEI/ARB group, the proportion of patients with severe or critical illness was 19.2% and 15.6% respectively. The main clinical symptoms in two groups were fever (80.8% vs. 84.4%) and cough (23.1% vs. 31.3%). The following parameters were comparable including lymphocyte counts, C-reactive protein, lactate dehydrogenase, D-dimer, bilateral involvement in chest CT (76.9% vs. 71.9%), worsening of COVID-19 (15.4% vs. 9.4%), favorable outcome (92.3% vs. 96.9%) between ACEI/ARB group and non-ACEI/ARB group respectively (all P>0.05). However, compared with non-ACEI/ARB group, serum creatinine [80.49 (68.72, 95.30) µmol/L vs. 71.29 (50.98, 76.98) µmol/L, P=0.007] was higher significantly in ACEI/ARB group. Conclusions: ACEI/ARB drugs have no significant effects on baseline clinical parameters (serum creatine and myoglobin excluded) , outcome, and prognosis of COVID-19 patients with hypertension. Antihypertensive drugs are not suggested to adjust in those patients, but the potential impairment of renal function as elevation of serum creatinine should be paid attention in patients administrating ACEI/ARB drugs.

Electronic patient-reported symptom monitoring in patients recovering from ambulatory minimally invasive gynecologic surgery: A prospective pilot study.

OBJECTIVE: To evaluate the feasibility of an electronic symptom-tracking platform for patients recovering from ambulatory surgery. METHOD: We assessed user response to an electronic system designed to self-report symptoms. Endpoints included compliance, postoperative symptoms, patient satisfaction. An 8-item symptom inventory (pain, nausea, vomiting, shortness of breath, fever, swelling, discharge, redness) was developed and made available on postoperative days (POD) 2-6. Responses exceeding defined thresholds of severity triggered alerts to healthcare providers. Symptoms, alerts, actions taken, urgent care center (UCC) visits, hospital admissions were tracked until POD 30. Patient satisfaction was evaluated on POD 7. A patient was defined as "responder" if at least 5/8 items on at least 3 PODs were completed. The assessment method was deemed successful if 64/100 patients responded. RESULTS: 97/102 patients were evaluable; 65 met "responder" criteria (67% responder rate; 95% CI 57-76%). 321 surveys were completed (median 4/patient), 248 (77%) in ≤2 min. Involving caregivers and allowing additional symptom-reporting improved the responder rate to 72% (95% CI 58-84%). Most commonly-reported moderate, severe, very severe symptoms were pain, nausea, swelling; 71% reported moderate to very severe pain on POD 2. Phone calls and adjustment of medications adequately addressed most symptoms. Two patients (2%) presented at UCC before, 6 (6%) after, POD 6; 1 (1%) was admitted. Most agreed or strongly agreed that electronic symptom-tracking was helpful, easy to use, and would recommend it to others. CONCLUSION: Electronic symptom-tracking is feasible for patients undergoing ambulatory gynecologic cancer surgery. Symptom burden is high in the early postoperative period. Addressing patient-reported symptoms in a timely, automated manner may prevent severe downstream adverse events, reduce UCC visits and admission rates, and improve outcomes.
