Abstract
COVID-19 is a highly infectious respiratory disease whose progression has been associated with multiple factors. From SARS-CoV-2 infection to death, biomarkers capable of predicting different disease processes are needed to help us further understand the molecular progression of COVID-19 disease. The aim is to find differentially expressed proteins that are associated with the progression of COVID-19 disease or can be potential biomarkers, and to provide a reference for further understanding of the molecular mechanisms of COVID-19 occurrence, progression, and treatment. Data-independent Acquisition (DIA) proteomics to obtain sample protein expression data, using R language screening differentially expressed proteins. Gene Ontology and Kyoto Encyclopedia for Genes and Genomes analysis was performed on differential proteins and protein-protein interaction (PPI) network was constructed to screen key proteins. A total of 47 differentially expressed proteins were obtained from COVID-19 incubation patients and healthy population (L/H), mainly enriched in platelet-related functions, and complement and coagulation cascade reaction pathways, such as platelet degranulation and platelet aggregation. A total of 42 differential proteins were obtained in clinical and latent phase patients (C/L), also mainly enriched in platelet-related functions and in complement and coagulation cascade reactions, platelet activation pathways. A total of 10 differential proteins were screened in recovery and clinical phase patients (R/C), mostly immune-related proteins. The differentially expressed proteins in different stages of COVID-19 are mostly closely associated with coagulation, and key differential proteins, such as FGA, FGB, FGG, ACTB, PFN1, VCL, SERPZNCL, APOC3, LTF, and DEFA1, have the potential to be used as early diagnostic markers.

A retrospective cohort study of the anesthetic management of postpartum tubal ligation. Int J Obstet Anesth 2024; 58:103974. [PMID: 38508961 DOI: 10.1016/j.ijoa.2023.103974] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 12/13/2023] [Accepted: 12/27/2023] [Indexed: 03/22/2024]
Abstract
BACKGROUND Neuraxial anesthesia with reactivation of a labor epidural catheter is commonly utilized for postpartum tubal ligations (PPTL), although the optimal anesthetic approach is unknown. We assessed institutional anesthesia practices for PPTL, and evaluated the failure rates of reactivation of labor epidural catheters, de novo spinal anesthesia, and spinal anesthesia after failed blocks. METHODS We conducted a single-center retrospective cohort analysis of 300 consecutive patients who underwent a PPTL and 100 having spinal anesthesia for cesarean delivery. Anesthetic management data (existing labor epidural catheter reactivation, de novo spinal anesthesia or general anesthesia) were collected from electronic medical records. Anesthetic block failure rates were determined for each anesthetic technique. RESULTS The failure rate was 15% for de novo spinal anesthesia and 23% after failed reactivation of a labor epidural catheter or spinal anesthesia. The epidural catheter reactivation failure rate was 35%. The failure rate of spinal anesthesia for cesarean delivery was 4%. Drug dosage, epidural catheter use in labor, time since epidural catheter placement or delivery, labor neuraxial technique (combined spinal-epidural, epidural), supplemental top-up doses during labor, and anesthesiologist experience did not predict neuraxial anesthesia failures. CONCLUSIONS Our analysis revealed an unexpectedly high neuraxial anesthesia failure rate even when de novo spinal anesthesia was used for PPTL. The results are consistent with other institutions' recent findings, and are higher than spinal anesthesia failure rates associated with cesarean delivery. Further studies are required to determine optimal anesthesia dosing strategies, and to understand the mechanisms behind high neuraxial anesthesia failures for PPTL.

Abstract
Disparities relating to postpartum recovery outcomes in different socio-economic and racial ethnic groups are underexplored. We conducted a planned analysis of a large prospective caesarean delivery cohort to explore the relationship between ethnicity, socio-economic status and postpartum recovery. Eligible patients were enrolled and baseline demographic, obstetric and medical history data were collected 18 h and 30 h following delivery. Patients completed postpartum quality of life and recovery measures in person on day 1 (EuroQoL EQ-5D-5L, including global health visual analogue scale; Obstetric Quality of Recovery-10 item score; and pain scores) and by telephone between day 28 and day 32 postpartum (EQ-5D-5L and pain scores). Socio-economic group was determined according to the Index of Multiple Deprivation quintile of each patient's usual place of residence. Data from 1000 patients who underwent caesarean delivery were included. There were more patients of Asian, Black and mixed ethnicity in the more deprived quintiles. Patients of White ethnicities had shorter postpartum duration of hospital stay compared with patients of Asian and Black ethnicities (35 (28-56 [18-513]) h vs. 44 (31-71 [19-465]) h vs. 49 (33-75 [23-189]) h, respectively. In adjusted models at day 30, patients of Asian ethnicity had a significantly greater risk of moderate to severe pain (numerical rating scale ≥ 4) at rest and on movement (odds ratio (95%CI) 2.42 (1.24-4.74) and 2.32 (1.40-3.87)), respectively). There were no differences in readmission rates or incidence of complications between groups. Patients from White ethnic backgrounds experience shorter postpartum duration of stay compared with patients from Asian and Black ethnic groups. Ethnic background impacts pain scores and recovery at day 1 postpartum and following hospital discharge, even after adjusting for socio-economic group. Further work is required to understand the underlying factors driving differences in pain and recovery and to develop strategies to reduce disparities in obstetric patients.

Comparison of outcomes after anterior cervical discectomy and fusion with and without a cervical collar: a systematic review and meta-analysis. J Orthop Surg Res 2024; 19:172. [PMID: 38454504 PMCID: PMC10919030 DOI: 10.1186/s13018-024-04661-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 03/02/2024] [Indexed: 03/09/2024] Open
Abstract
PURPOSE The clinical outcomes of patients who received a cervical collar after anterior cervical decompression and fusion were evaluated by comparison with those of patients who did not receive a cervical collar. METHODS All of the comparative studies published in the PubMed, Cochrane Library, Medline, Web of Science, and EMBASE databases as of 1 October 2023 were included. All outcomes were analysed using Review Manager 5.4. RESULTS Four studies with a total of 406 patients were included, and three of the studies were randomized controlled trials. Meta-analysis of the short-form 36 results revealed that wearing a cervical collar after anterior cervical decompression and fusion was more beneficial (P < 0.05). However, it is important to note that when considering the Neck Disability Index at the final follow-up visit, not wearing a cervical collar was found to be more advantageous. There were no statistically significant differences in postoperative cervical range of motion, fusion rate, or neck disability index at 6 weeks postoperatively (all P > 0.05) between the cervical collar group and the no cervical collar group. CONCLUSIONS This systematic review and meta-analysis revealed no significant differences in the 6-week postoperative cervical range of motion, fusion rate, or neck disability index between the cervical collar group and the no cervical collar group. However, compared to patients who did not wear a cervical collar, patients who did wear a cervical collar had better scores on the short form 36. Interestingly, at the final follow-up visit, the neck disability index scores were better in the no cervical collar group than in the cervical collar group.

Effects of continuous intravenous infusion with propofol on intestinal metabolites in rats. Biomed Rep 2024; 20:25. [PMID: 38169795 PMCID: PMC10758916 DOI: 10.3892/br.2023.1713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 05/18/2023] [Indexed: 01/05/2024] Open
Abstract
Microbial metabolites play an important role in regulating intestinal homeostasis and immune responses. Propofol is a common anesthetic in clinic, but it is not clear whether it affects intestinal metabolites in rats. Tail vein puncture was performed after adaptive feeding for 1 month in eight 2-month-old rats and they were given continuous intravenous infusion of propofol for 3 h. The feces of rats were divided into different groups based on time periods, with before and after anesthesia with propofol on days 1, 3 and 7 labeled as groups P, A1, A3 and A7, respectively. The effect of continuous intravenous infusion with propofol on rat fecal metabolites was determined using the non-targeted metabolomics technique gas chromatography coupled with a time-of-flight mass spectrometer analysis. The types and contents of metabolites in rat feces were changed after continuous intravenous infusion with propofol, but the changes were not statistically significant. The contents of the metabolites 3-hydroxyphenylacetic acid and palmitic acid increased from day 3 to 7, and it was shown that the two metabolites were positively correlated at a statistically significant level. Linoleic acid decreased to its lowest level on day 3, and it returned to pre-anesthesia level on day 7. At the same time, linoleic acid metabolism was a metabolic pathway that was co-enriched 7 days after infusion with propofol. Spearman correlation analysis showed that there was significant correlation between some differential metabolites and differential microorganisms. It was observed that zymosterol 1, cytosin and elaidic acid were negatively correlated with Alloprevotella in the A3 vs. P group. In the A7 vs. P group, cortexolone 3 and coprostan-3-one were positively correlated with Faecalibacterium, whilst aconitic acid was negatively correlated with it. In conclusion, the present study revealed statistically insignificant effects of continuous intravenous propofol on the intestinal metabolites in rats.

Abstract
Background Adjacent segmental degeneration after lumbar fusion is one of the common long-term complications after lumbar fusion. With the continuous development of adjacent segmental degeneration, patients who fail conservative treatment often need reoperation to relieve symptoms. In recent years, the technique of bilateral microdecompression through unilateral approach under microchannel has been widely used in the treatment of lumbar degenerative diseases. However, the efficacy of this procedure for adjacent-segment degeneration after lumbar fusion has not been established. Here, we report a case of bilateral microscopic decompression via a unilateral approach through a microchannel in a patient with adjacent segmental degeneration after lumbar fusion. Case report A 70-year-old male patient was admitted to hospital because of lumbago accompanied by left lower extremity pain, numbness and weakness for 2 years, which aggravated for 2 months. Ten years ago, he underwent PLIF for lumbar spinal stenosis, and recovered well after the operation. According to imaging data and physical examination, the diagnosis was adjacent segmental degeneration after lumbar fusion. Bilateral microdecompression was performed through a unilateral approach under a microchannel. Good clinical outcomes was observed through 1-year postoperative follow-up. Conclusions This report reports the successful treatment of a patient with ASD 10 years after lumbar fusion. Bilateral microdecompression via a unilateral approach under a microchannel is a safe and effective method for the treatment of ASD after lumbar fusion with good surgical outcomes.

Abstract
OBJECTIVE To describe the prevalence and predictors of postpartum sleep disorders. DESIGN A retrospective cohort study. SETTING Postpartum. POPULATION Commercially insured women delivering in California (USA) between 2011 and 2014. METHODS Using the Optum Clinformatics Datamart Database. MAIN OUTCOME MEASURES Prevalence of a postpartum sleep disorder diagnosis with and without a depression diagnosis up to 12 months following hospital discharge for inpatient delivery. We also identified predictors of a postpartum sleep disorder diagnosis using multivariable logistic regression. RESULTS We identified 3535 (1.9%) women with a postpartum sleep disorder diagnosis. The prevalence of sleep disorder diagnoses was insomnia (1.3%), sleep apnea (0.25%), and other sleep disorder (0.25%). The odds of a postpartum sleep disorder were highest among women with a history of drug abuse (adjusted odds ratio (aOR): 2.70, 95% confidence interval (CI): 1.79-4.09); a stillbirth delivery (aOR: 2.15, 95% CI: 1.53-3.01); and chronic hypertension (aOR: 1.82; 95% CI: 1.57-2.11). A comorbid diagnosis of a postpartum sleep disorder and depression occurred in 1182 women (0.6%). These women accounted for 33.4% of all women with a postpartum sleep disorder. The strongest predictors of a comorbid diagnosis were a history of drug abuse (aOR: 4.13; 95% CI: 2.37-7.21) and a stillbirth delivery (aOR: 2.93; 95% CI: 1.74-4.92). CONCLUSIONS Postpartum sleep disorders are underdiagnosed conditions, with only 2% of postpartum women in this cohort receiving a sleep diagnosis using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes. Insomnia was the most common disorder and one-third of women diagnosed with a postpartum sleep disorder had a co-morbid diagnosis of depression. Future studies are needed to improve the screening and diagnostic accuracy of postpartum sleep disorders.

Abstract
To measure the expression of angiotensin converting enzyme 2 (ACE2) mRNA in SARS-CoV-2 infection with different infection status and at different stages during infection, we used RT-qP CR to measure the expression of ACE2 mRNA. Measurements were analyzed by two-way repeated measures analysis of variance (RMANOVA). Expression of ACE2 mRNA was downregulated in initial stages of SARS-CoV-2 infection both in the asymptomatic infection (ASY) group and the confirmed cases (CON) group (t=-8.0845, P < 0.0001; t=-8.1904, P < 0.0001, respectively). The expression of ACE2 mRNA in the incubation period of CON group was lower compared with the intinal period of ASY group (F = 6.084, p = 0.016, partialη2 = 0.070). Relative expression of ACE2 mRNA was upregulated at the late stage of SARS-CoV-2 infection in the ASY and CON groups (F = 23.489, p = 0.000, partialη2 = 0.225; F = 46.555, p = 0.000, partialη2 = 0.365, respectively). The relative expression of ACE2 mRNA was down-regulated (mean ± SEM:0.69 ± 0.03) after inoculation with SARSCoV- 2 Spike pseudovirus, and there was a statistical difference (one-way t test, mean diffience =-0.31, 95%CI: -0.37˜-0.24, t=-8.1904, P < 0.0001). The expression of ACE2 mRNA is downregulated in the initial stage of SARS-CoV-2 infection, and then upregulated in the late stage of SARS-CoV-2 infection. The lower expression of ACE2 mRNA during the incubation period can lead to clinical symptoms. Downregulation of ACE2 mRNA was related to the interaction between SARS-CoV-2 S protein and ACE2.Communicated by Ramaswamy H. Sarma.

Abstract
The grain size plays a pivotal role in determining the properties of the alloy. The grain size can be significantly decreased by adding inoculants. Aiming to address the shortcomings of existing inoculants, the Al3Ti-Al2O3/Al inoculant was successfully prepared using Al-Ti master alloy and Al2O3 whiskers as raw materials. With the aid of ultrasonic energy, the Al2O3 whiskers were uniformly dispersed within the inoculants. Under the combined action of ultrasonic and titanium, the Al2O3 whiskers were broken into small particles at high temperature. To enhance the morphology of Al3Ti and achieve even particle dispersion throughout the matrix, vacuum rapid quenching treatment was applied to the inoculant. The SEM test results indicated a significant reduction in particle size after vacuum rapid quenching. The Al3Ti-Al2O3/Al inoculants exhibited excellent grain refinement effects on the weldable Al-Cu-Mn alloy. Crystallographic calculations and HRTEM analysis revealed that Al2O3 and Al have orientation relationships, indicating their potential as effective heterogeneous nucleation sites. The mechanical properties of the Al-Cu-Mn alloy were obviously improved after the Al3Ti-Al2O3/Al inoculant was added.

Abstract
PURPOSE The clinical outcomes of using a tubular microdiscectomy for lumbar disc herniation were evaluated by comparison with conventional microdiscectomy. METHODS All of the comparative studies published in the PubMed, Cochrane Library, Medline, Web of Science, and EMBASE databases as of 1 May 2023 were included. All outcomes were analysed using Review Manager 5.4. RESULTS This meta-analysis included four randomized controlled studies with a total of 523 patients. The results showed that using tubular microdiscectomy for lumbar disc herniation was more effective than conventional microdiscectomy in improving the Oswestry Disability Index (P < 0.05). However, there were no significant differences in operating time, intraoperative blood loss, hospital stay, Visual Analogue Scale, reoperation rate, postoperative recurrence rate, dural tear incidence, and complications rate (all P > 0.05) between the tubular microdiscectomy and conventional microdiscectomy groups. CONCLUSIONS Based on our meta-analysis, it was found that the tubular microdiscectomy group had better outcomes than the conventional microdiscectomy group in terms of Oswestry Disability Index. However, there were no significant differences between the two groups in terms of operating time, intraoperative blood loss, hospital stay, Visual Analogue Scale, reoperation rate, postoperative recurrence rate, dural tear incidence, and complications rate. Current research suggests that tubular microdiscectomy can achieve clinical results similar to those of conventional microdiscectomy. PROSPERO registration number is: CRD42023407995.

Abstract
To better understand outcomes in postpartum patients who receive peripartum anaesthetic interventions, we aimed to assess quality of recovery metrics following childbirth in a UK-based multicentre cohort study. This study was performed during a 2-week period in October 2021 to assess in- and outpatient post-delivery recovery at 1 and 30 days postpartum. The following outcomes were reported: obstetric quality of recovery 10-item measure (ObsQoR-10); EuroQoL (EQ-5D-5L) survey; global health visual analogue scale; postpartum pain scores at rest and movement; length of hospital stay; readmission rates; and self-reported complications. In total, 1638 patients were recruited and responses analysed from 1631 (99.6%) and 1282 patients (80%) at one and 30 days postpartum, respectively. Median (IQR [range]) length of stay postpartum was 39.3 (28.5-61.0 [17.7-513.4]), 40.3 (28.5-59.1 [17.8-220.9]), and 35.9 (27.1-54.1 [17.9-188.4]) h following caesarean, instrumental and vaginal deliveries, respectively. Median (IQR [range]) ObsQoR-10 score was 75 ([62-86] 4-100) on day 1, with the lowest ObsQoR-10 scores (worst recovery) reported by patients undergoing caesarean delivery. Of the 1282 patients, complications within the first 30 days postpartum were reported by 252 (19.7%) of all patients. Readmission to hospital within 30 days of discharge occurred in 69 patients (5.4%), with 49 (3%) for maternal reasons. These data can be used to inform patients regarding expected recovery trajectories; facilitate optimal discharge planning; and identify populations that may benefit most from targeted interventions to improve postpartum recovery experience.

Stability of Attention Performance of Adults with ADHD over Time: Evidence from Repeated Neuropsychological Assessments in One-Month Intervals. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:15234.

Abstract
Neuropsychological assessments of attention are valuable sources of information in the clinical evaluation of adults with attention-deficit/hyperactivity disorder (ADHD). However, it is unclear whether the attention performance of adults with ADHD is stable or fluctuates over time, which is of great importance in the interpretation of clinical assessments. This study aimed to explore the stability of attention performance of adults with ADHD in repeated assessments at one-month intervals. Twenty-one adults diagnosed with ADHD took part in this study by completing selective attention and vigilance tests three times, each one month apart. Test scores of participants were compared with and interpreted based on test norms. A considerable proportion of 'below average' performance scores were observed in most of the variables of selective attention and vigilance in all three assessments. Further, selective attention and vigilance performance scores did not differ significantly between the three repeated assessments. Finally, the majority of participants received consistent test score interpretations across the three repeated assessments. This study confirms previous research and highlights abnormal selective attention and vigilance performance in adults with ADHD. Further, this study preliminarily demonstrates relatively stable attention performance across repeated assessments, which has the potential to support clinical assessment, treatment planning, and evaluation.

Abstract
This study applied network analysis to explore the relations between neuropsychological functions of individuals in the clinical evaluation of attention-deficit/hyperactivity disorder (ADHD) in adulthood. A total of 319 participants from an outpatient referral context, that is, 173 individuals with ADHD (ADHD group) and 146 individuals without ADHD (n-ADHD group), took part in this study and completed a comprehensive neuropsychological assessment. A denser network with stronger global connectivity was observed in the ADHD group compared to the n-ADHD group. The strongest connections were consistent in both networks, that is, the connections between selective attention and vigilance, and connections between processing speed, fluency, and flexibility. Further centrality estimation revealed attention-related variables to have the highest expected influence in both networks. The observed relationships between neuropsychological functions, and the high centrality of attention, may help identify neuropsychological profiles that are specific to ADHD and optimize neuropsychological assessment and treatment planning of individuals with cognitive impairment.

Abstract
BACKGROUND We aimed to develop and validate a Portuguese version of the Obstetric Quality of Recovery-10 (ObsQoR-10-Portuguese) patient-reported outcome measure and evaluate its psychometric properties. METHODS After ethical approval, we recruited term pregnant women undergoing uncomplicated elective cesarean delivery in a single Brazilian institution. Women were invited to complete the translated ObsQoR-10-Portuguese and EuroQoL (EQ-5D) questionnaires (including a global health visual analog scale [GHVAS]) at 24 h (±6 h) following delivery, and a subset of women an hour later. We assessed validity and reliability of ObsQoR-10-Portuguese. RESULTS One hundred thirteen enrolled women completed the surveys at 24 h and 29 women at 25 h (100% response rate). VALIDITY (i) convergent validity: ObsQoR-10-Portuguese correlated moderately with EuroQoL score (r = -0.587) and GHVAS score (r = 0.568) at 24 h. (ii) Discriminant validity: ObsQoR-10 discriminated well between good versus poor recovery (GHVAS score ≥ 70 versus < 70; difference in mean scores 14.2; p < 0.001). (iii) Hypothesis testing: 24-h ObsQoR-10-Portuguese scores correlated with gestational age (r = 0.191; p = 0.043). (iv) Cross-cultural validity: differential item functioning analysis suggested bias in 2 items. Reliability: (i) internal consistency was good (Cronbach's alpha = 0.82 and inter-item correlation = 0.31). (ii) Split-half reliability was very good (Spearman-Brown Prophesy Reliability Estimate = 0.80). (iii) Test re-test reliability was excellent (intra-class correlation coefficient = 0.87). (iv) Floor and ceiling effects: < 5% women scored either 0 or 100 (lowest and highest scores, respectively). CONCLUSION ObsQoR-10-Portuguese is valid and reliable, and should be considered for use in Portuguese-speaking women to assess their quality of inpatient recovery following cesarean delivery.

It Takes Time: Vigilance and Sustained Attention Assessment in Adults with ADHD. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19095216. [PMID: 35564612 PMCID: PMC9102294 DOI: 10.3390/ijerph19095216] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 04/20/2022] [Accepted: 04/23/2022] [Indexed: 12/10/2022]
Abstract
Objectives: The present study compares the utility of eight different tests of vigilance and sustained attention in the neuropsychological examination of adults with Attention-deficit/hyperactivity disorder (ADHD). Methods: Thirty-one adults diagnosed with ADHD performed eight tests for vigilance and sustained attention, spread over three assessment days. Results: Adults with ADHD showed cognitive impairments in most tests and test variables, even though their sensitivity differed greatly. No specific type of test variable stands out to be the most sensitive, and no evidence for a differential deterioration of performance over time was observed. Conclusion: This study underscores the role of vigilance and sustained attention tests in the assessment of adult ADHD. It is further concluded that summary scores over the entire test duration are sufficient, but that all variables of a test should be considered. Finally, we hypothesize that reassessment on a different day may benefit a more accurate clinical assessment of adults with ADHD, in order to adequately take intraindividual fluctuations and limitations regarding test reliability into account.

Comparison of outcomes between Zero-p implant and anterior cervical plate interbody fusion systems for anterior cervical decompression and fusion: a systematic review and meta-analysis of randomized controlled trials. J Orthop Surg Res 2022; 17:47. [PMID: 35078496 PMCID: PMC8787904 DOI: 10.1186/s13018-022-02940-w] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Accepted: 01/13/2022] [Indexed: 11/17/2022] Open
Abstract
Purpose The clinical outcomes of using a zero-profile for anterior cervical decompression and fusion were evaluated by comparison with anterior cervical plates. Methods All of the comparative studies published in the PubMed, Cochrane Library, Medline, Web of Science, EBSOChost, and EMBASE databases as of 1 October 2021 were included. All outcomes were analysed using Review Manager 5.4. Results Seven randomized controlled studies were included with a total of 528 patients, and all studies were randomized controlled studies. The meta-analysis outcomes indicated that the use of zero-profile fixation for anterior cervical decompression and fusion was better than anterior cervical plate fixation regarding the incidence of postoperative dysphagia (P < 0.05), adjacent-level ossification (P < 0.05), and operational time (P < 0.05). However, there were no statistically significant differences in intraoperative blood loss, Visual Analogue Scale, Neck Disability Index, or Japanese Orthopaedic Association scale (all P > 0.05) between the zero-profile and anterior cervical plate groups. Conclusions The systematic review and meta-analysis indicated that zero-profile and anterior cervical plates could result in good postoperative outcomes in anterior cervical decompression and fusion. No significant differences were found in intraoperative blood loss, Visual Analogue Scale, Neck Disability Index, or Japanese Orthopaedic Association scale. However, the zero-profile is superior to the anterior cervical plate in the following measures: incidence of postoperative dysphagia, adjacent-level ossification, and operational time.

Identification of distinct clinical phenotypes of acute respiratory distress syndrome with differential responses to treatment. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2021; 25:320. [PMID: 34461969 PMCID: PMC8404019 DOI: 10.1186/s13054-021-03734-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Accepted: 08/18/2021] [Indexed: 02/05/2023]
Abstract
Background Acute respiratory distress syndrome (ARDS) is a heterogeneous syndrome, and the identification of homogeneous subgroups and phenotypes is the first step toward precision critical care. We aimed to explore whether ARDS phenotypes can be identified using clinical data, are reproducible and are associated with clinical outcomes and treatment response. Methods This study is based on a retrospective analysis of data from the telehealth intensive care unit (eICU) collaborative research database and three ARDS randomized controlled trials (RCTs) (ALVEOLI, FACTT and SAILS trials). We derived phenotypes in the eICU by cluster analysis based on clinical data and compared the clinical characteristics and outcomes of each phenotype. The reproducibility of the derived phenotypes was tested using the data from three RCTs, and treatment effects were evaluated. Results Three clinical phenotypes were identified in the training cohort of 3875 ARDS patients. Of the three phenotypes identified, phenotype I (n = 1565; 40%) was associated with fewer laboratory abnormalities, less organ dysfunction and the lowest in-hospital mortality rate (8%). Phenotype II (n = 1232; 32%) was correlated with more inflammation and shock and had a higher mortality rate (18%). Phenotype III (n = 1078; 28%) was strongly correlated with renal dysfunction and acidosis and had the highest mortality rate (22%). These results were validated using the data from the validation cohort (n = 3670) and three RCTs (n = 2289) and had reproducibility. Patients with these ARDS phenotypes had different treatment responses to randomized interventions. Specifically, in the ALVEOLI cohort, the effects of ventilation strategy (high PEEP vs low PEEP) on ventilator-free days differed by phenotype (p = 0.001); in the FACTT cohort, there was a significant interaction between phenotype and fluid-management strategy for 60-day mortality (p = 0.01). The fluid-conservative strategy was associated with improved mortality in phenotype II but had the opposite effect in phenotype III. Conclusion Three clinical phenotypes of ARDS were identified and had different clinical characteristics and outcomes. The analysis shows evidence of a phenotype-specific treatment benefit in the ALVEOLI and FACTT trials. These findings may improve the identification of distinct subsets of ARDS patients for exploration in future RCTs.

Neuropsychological functioning of individuals at clinical evaluation of adult ADHD. J Neural Transm (Vienna) 2021; 128:877-891. [PMID: 33355692 PMCID: PMC8295106 DOI: 10.1007/s00702-020-02281-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Accepted: 11/18/2020] [Indexed: 11/26/2022]
Abstract
OBJECTIVES Numerous studies showed that adults with attention deficit hyperactivity disorder (ADHD) suffer from impairments in a range of cognitive functions when compared to healthy controls. However, only little is known about the neuropsychological functions when compared to various clinical control groups and whether a distinct neuropsychological profile can be identified for adult ADHD. METHOD This retrospective study examined data of 199 outpatients referred for clinical evaluation of adult ADHD, allocated either to an ADHD group (n = 78) or to one of two clinical comparison groups, depending on whether they show indications (n = 71) or no indications (n = 50) for the presence of psychiatric disorders other than ADHD. All individuals performed a comprehensive neuropsychological test battery. RESULTS Data analysis revealed impairments in a range of cognitive functions in a substantial number of patients of all three groups. However, profiles of neuropsychological impairments were similar between groups. Furthermore, significant small- to medium-sized correlations between basic and higher-order cognitive functions were revealed in the ADHD group and the clinical comparison group with indications for psychiatric disorders other than ADHD. CONCLUSION Neuropsychological impairments are prominent in psychiatric outpatients seeking a clinical evaluation of adult ADHD but are not specific for ADHD. It is concluded that neuropsychological test performance may have limited incremental value to support the psychiatric differential diagnosis. Furthermore, a clinical trajectory may need to take into account that deficits in a range of higher-order cognitive functions can be substantially explained by deficits in basic cognitive functions.

Volatile Organic Compounds to Identify Infectious (Bacteria/Viruses) Diseases of the Central Nervous System: A Pilot Study. Eur Neurol 2021; 84:325-332. [PMID: 34182565 DOI: 10.1159/000507188] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Accepted: 03/07/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND Central nervous system (CNS) infectious diseases are common diseases in emergency rooms and neurology departments. CNS pathogen identification methods are time consuming and expensive and have low sensitivity and poor specificity. Some studies have shown that bacteria and viruses can produce specific volatile organic compounds (VOCs). The aim of this study is to find potential biomarkers by VOC analysis of cerebrospinal fluid (CSF) in patients with bacterial and viral meningitis/encephalitis (ME). METHODS CSF samples from 16 patients with bacterial ME and 42 patients with viral ME were collected, and solid-phase microextraction combined with gas chromatography-mass spectrometry was used to analyze the metabolites in the CSF. RESULTS There are 2 substances (ethylene oxide and phenol) that were found to be different between the 2 groups. Ethylene oxide was significantly greater in the group of bacterial ME patients than in the viral ME group of patients (p < 0.05). In addition, phenol was remarkably increased in the group of ME patients compared with the bacterial ME patients (p < 0.05). CONCLUSIONS Ethylene oxide and phenol may be potential biomarkers to distinguish bacterial ME and viral ME. VOC analysis of CSF may be used as a supporting tool for clinical diagnosis.

Abstract
OBJECTIVE The aim of this study was to explore the effects of oral and intestinal florae and serum inflammatory factors on the pathogenesis of oral cancer. PATIENTS AND METHODS Oral cancer patients and healthy subjects in our hospital were enrolled in disease group (n=50) and control group (n=50), respectively. Oral flora of subjects was collected using the sterile cotton swab. Microbial deoxyribonucleic acid (DNA) was extracted for Polymerase Chain Reaction (PCR) amplification and sequencing. Subsequently, the feces were also collected from patients, and sent to the company for analysis of microbial composition via sequencing. In addition, the levels of serum inflammatory factors tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), IL-6, and IL-1β in disease group and control group were detected via enzyme-linked immunosorbent assay (ELISA). RESULTS The number of patients with a history of drinking (p=0.040) and betel nut chewing (p=0.000) in the disease group was larger than that in the control group, and the difference was statistically significant. In terms of oral flora distribution, the ratios of dominant bacteria Staphylococcus and Rothia were 64% and 50% in disease group, which were significantly higher than those in the control group (24% and 18%) (p=0.023 and 0.034). In terms of intestinal flora distribution, the abundance of intestinal florae (Flavobacteriaceae, Sphingobacteriales, Rikenella, Pseudomonadales, Tetragenococcus and Acinetobacter) in the disease group was remarkably higher than that in the control group (p<0.05). However, the abundance of Vagococcus and Pediococcus in control group was significantly higher than that in the disease group (p<0.05). Among intestinal flora, Firmicutes exhibited a highly positive correlation with Bacteroides (r=0.341, p=0.023), and a highly negative correlation with Ruminococcus (r=-0.832, p=0.000). Bacteroides had a highly negative correlation with Lactobacillus (r=-0.763, p=0.000) and Enterococcus (r=-0.461, p=0.000). In disease group, the levels of TNF-α (p=0.021), IL-8 (p=0.000), and IL-1β (p=0.000) were evidently higher than those in the control group [(23.51±2.14) ng/L vs. (12.34±2.45) ng/L, (89.75±4.29) ng/L vs. (43.23±3.25) ng/L, (42.25±3.25) ng/L vs. (15.32±1.47) ng/L]. However, there was no statistically significant difference in IL-6 level between the two groups (p=0.217). CONCLUSIONS Oral and intestinal florae and serum inflammatory factors are associated with the pathogenesis of oral cancer.

Abstract
Background:Prior studies have shown that in the real-world setting, rheumatoid arthritis (RA) patients have lower disease activity than those studied in clinical trials. However, randomized controlled trials for biologics continue to mainly recruit patients with severe disease.Objectives:To assess the implications of this practice, our study investigates the proportion of patients achieving remission (DAS28-ESR ≤ 2.6), in RA patients with moderate disease activity and severe disease activity, at 12 months post starting their first biologic, and identifies baseline predictors of biologic response.Methods:This study included RA patients who have never been treated with a biologic and initiated their first biologic while enrolled in the Ontario Best Practices Research Initiative (OBRI) registry, between 2008 and 2019. Patients selected had either moderate RA (DAS28 ≥ 3.2 to ≤ 5.1) or severe RA (DAS28 > 5.1). Comparisons were made between the moderate and severe disease groups using the student’s t-test for continuous variables, and the chi-square test for categorical variables. Multivariable logistic regression was used to test potential predictors of remission. Backward stepwise model selection was applied to select variables with p-value ≤0.10. Multiple imputation (MCMC method; n=20) was used to impute missing data.Results:Overall, 641 patients initiated their first biologic, 483 had follow up data at 12 months (moderate disease activity=264; severe disease activity=219). In the moderate group, the mean age (SD) was 55.7 (13.1) and 80% were female. In the severe group, mean age (SD) was 58.4 (12.3) and 81% were female. At time of biologic initiation, the mean DAS28 for the moderate group was 4.1 (0.5), and 6.0 (0.6) for the severe group. After 12 months of starting a biologic, the proportion of patients achieving remission was 50% in the moderate group, and 23% in the severe group (p<0.0001). In contrast, the proportion of patients achieving significant clinical change from baseline (improvement in DAS28 ≥ 1.2) was 78% in the severe group, compared to 66% in the moderate group (p=0.0049). More specifically, the absolute improvement in DAS28 after 12 months was higher in the severe group at 2.2 (1.5), compared to a change of 1.4 (1.3) in the moderate group (p<0.0001). Negative predictors of remission include female gender (odds ratio (OR), 0.57, 95% confidence interval (CI), 0.33-0.97; p=0.039), and higher HAQ-DI score (OR 0.49, 95% CI 0.36-0.68; p<0.001). In turn, moderate disease at time of biologic initiation (OR 2.38, 95% CI 1.50-3.79; p=0.0390) was identified as a positive predictor of remission.Conclusion:This prospective cohort study found RA patients with moderate disease activity are more likely to reach targeted states (remission and low disease activity), whereas severe patients have greater absolute improvements in DAS28 and HAQ-DI but are less likely to achieve remission. Moderate disease is a positive predictor for remission, whereas female gender and a higher HAQ-DI score are negative predictors.Table 1.Logistic regression analysis for the rate of achieving DAS28 low disease activity at six months.Moderate-RA(n=264)Severe-RA(n=219)P-ValueRemission, n (%)111 (50)45 (23)<0.0001Low disease activity, n (%)151 (59)74 (35)<0.0001Change in DAS from baseline ≥ 1.2, n (%)168 (66)164 (78)0.0049HAQ-DI change >0.22, n (%)98 (53)83 (52)0.7974Change in DAS28 from baseline, mean (SD)-1.4 (1.3)-2.2 (1.5)<0.0001Change in HAQ-DI from baseline, mean (SD)-0.29 (0.57)-0.30 (0.66)<0.0001Change in fatigue from baseline, mean (SD)-0.98 (3.2)-1.11 (3.2)<0.0001Change in sleep from baseline, mean (SD)-0.85 (3.6)-1.05 (3.9)0.0004Disclosure of Interests:Nancy Guo: None declared, Xiuying Li: None declared, Mohammad Movahedi: None declared, Angela Cesta: None declared, Claire Bombardier Grant/research support from: OBRI was funded by peer reviewed grants from CIHR (Canadian Institute for Health Research), Ontario Ministry of Health and Long-Term Care (MOHLTC), Canadian Arthritis Network (CAN) and unrestricted grants from: Abbvie, Amgen, Aurora, Bristol-Meyers Squibb, Celgene, Hospira, Janssen, Lilly, Medexus, Merck, Novartis, Pfizer, Roche, Sanofi, & UCB.Acknowledgment: :Dr. Bombardier held a Canada Research Chair in Knowledge Transfer for Musculoskeletal Care and a Pfizer Research Chair in Rheumatology

Abstract
Hepatoblastoma (HB) is the predominant hepatic neoplasm in infants and young children. Sorafenib has been used to treat adult and pediatric hepatocellular carcinoma. However, efficacy of monotherapy of sorafenib in HB is not sustained. In this study, we tested a possible combinatory therapy of sorafenib with the CCAAT/enhancer-binding proteins (C/EBP) overexpression in HB cell line. Firstly, we evaluated the expression level of C/EBPβ in the patients with HB by analyzing The Cancer Genome Atlas data. Lower level of C/EBPβ was observed in tumor tissues in comparison with matched normal tissues. Next, we observed that combination of sorafenib and C/EBPβ overexpression led to dramatic growth and migration inhibition of live tumor cells which implied promising probability for clinical trial. Mechanistically, C/EBPβ which can be downregulated by Ras v12, augmented messenger RNA and protein levels of p53. These data suggested that a combination of sorafenib and C/EBPβ overexpression inhibited tumor growth synergistically and provided a promising approach to treat HB.

Abstract
Although inflammation is protective of the body, uncontrolled acute inflammatory reactions may inflict tissue damage and lead to chronic inflammation. There is a fast-growing research interest in mechanisms that mediate regression of inflammation and actions of anti-inflammatory factors. Studies of inflammatory and anti-inflammatory mechanisms have uncovered roles for new lipid mediators, including lipoxins, resolvins, protectins, and maresins, collectively referred to as specialized pro-resolving mediators (SPM). Maresins have recently been discovered and are biosynthesized from docosahexaenoic acid (DHA) by macrophages and display strong anti-inflammatory and pro-resolving activities. Here, we summarize the actions and mechanisms of maresins in different diseases and suggest possible therapeutic uses.

Abstract
OBJECTIVE To investigate the sensitivity of adult worms of filial generations from praziquantel-resistant and -sensitive Schistosoma japonicum mixed infections to praziquantel. METHODS Mice were infected with the cercariae of an experimentally generated praziquantel-resistant S. japonicum isolate [median effective dose (ED50) = 277.4 mg/kg] and a laboratory-maintained praziquantel-sensitive S. japonicum isolate (ED50 = 99.6 mg/kg) at a mixture ratio of 1:1 and 2:1, which was maintained in the laboratory via the mouse-snail cycle for 8 generations. Then, mice were infected with the cercariae of the 8th filial-generation parasite, and grouped 35 days post-infection. Mice in the 5 treatment groups were given praziquantel treatment by gavage at a single oral dose of 37.5, 75, 150, 300 mg/kg and 600 mg/kg, while animals in the control group was administered orally with 2.5% cremophor EL. All mice were sacrificed 14 days post-treatment and adult worms were collected by perfusion of the portal vein. The worm burden reductions and praziquantel ED50 values were calculated. The praziquantel-resistant S. japonicum isolate generated from experimental induction with 12 rounds of praziquantel treatment with sub-curative doses was maintained in the laboratory via the mouse-snail cycle, and mice were infected with the cercariae of the 8th filial-generation parasite. The praziquantel ED50 value against the 8th filial-generation adults was measured. RESULTS After mice were infected with the mixture of cercariae of PZQ-resistant and -sensitive S. japonicum isolates at a ratio of 1:1, the praziquantel ED50 was 135.2 mg/kg against the adults of the 8th filial-generation parasite. After mice were infected with the mixture of cercariae of PZQ-resistant and -sensitive S. japonicum isolates at a ratio of 2:1, the praziquantel ED50 was 129.2 mg/kg against the adults of the 8th filial-generation parasite. In addition, the praziquantel ED50 was 208.4 mg/kg against the adults of the 8th filial-generation S. japonicum without the selection pressure of praziquantel. CONCLUSIONS Compared with the experimentally induced praziquantel-resistant S. japonicum isolate, the adult worms of the filial-generation S. japonicum show a reduced sensitivity to praziquantel in the same host following infection with the mixture of cercariae of praziquantel-resistant and -sensitive S. japonicum isolates. The adult worms of the filial generation of the praziquantel-resistant S. japonicum isolate without the selection pressure of praziquantel may still maintain the resistance to praziquantel.

Abstract
OBJECTIVE The involvement of long non-coding RNA (LncRNAs) in HCC development has been widely recognized in recent decades. LncRNA small nucleolar RNA host gene 5 (SNHG5) has been identified to be implicated in the development of many tumors, and this study aimed to explore the role of SNHG5 in HCC tumorigenesis. PATIENTS AND METHODS The expression levels of SNHG5, miR-363-3p, and Ring Finger Protein 38 (RNF38) were measured by using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) or Western blot assay, respectively. Cell proliferation was analyzed by MTT assay. Flow cytometry was used to investigate cell apoptosis. Cell migration and invasion abilities were detected by transwell assay. The relationship among SNHG5, miR-363-3p, and RNF38 was confirmed using bioinformatics analysis and Luciferase reporter assay. RESULTS The expression of SNHG5 and RNF38 was elevated in HCC tissues and cell lines, and highly expressed SNHG5 and RNF38 could induce apoptosis and repress proliferation, migration, as well as invasion in HCC cells. Further investigations showed that SNHG5 might act as a competing endogenous RNA of miR-26a-5p and thereby cause the derepression of the downstream target RNF38. Moreover, rescue experiments indicated that SNHG5 silence inhibited the progression of HCC cells by regulating miR-363-3p, and the facilitated effects of RNF38 in the progression of HCC cells were regulated by miR-363-3p. CONCLUSIONS LncRNA SNHG5 may promote human HCC progression by regulating the miR-363-3p/RNF38 axis, providing a novel insight into the pathogenesis of HCC and therapeutic strategy for HCC treatment.

Abstract
BACKGROUND To investigate the changes of intestinal microbiota and metabolites in sepsis mice with acute gastrointestinal injury before and after the use of antibiotics, and to explore the possible effects of these changes on the body. METHODS Twenty-four 6-8-w-old SPF-grade C57BL/6J male mice were selected, and the mice were randomly divided into three groups. The mice were treated by tail vein injection for 3 days. The intestinal motility of mice after administration was detected. The mice feces were collected for 16S rRNA and Untargeted metabonomics detection. RESULTS The use of antibiotics in sepsis mice can change the composition of intestinal microbiota and metabolites. LD3, AD3 and LAD3 samples had significant differences in bacterial species. Desulfovibrio was the species with a significant difference in LAD3. In addition, we found that the composition of those intestinal microbiota were correlated with changes in intestinal motility. The untargeted metabolomics analysis showed that the fecal metabolites of LD3 and LAD3 samples were significantly different. In addition to the basic metabolites, Benzoic acid and 4-Hydroxybenzoic acid were also found, and Desulfovibrio was associated with them. CONCLUSIONS The use of antibiotics in sepsis mice can lead to changes in the intestinal microbiota and metabolite levels, which may be related to the severity of acute gastrointestinal injury in sepsis mice. Inhibiting Desulfovibrio in the intestine and using Benzoic acid and 4-Hydroxybenzoic acid as a marker for the production of Desulfovibrio may reduce the inflammatory degree of acute gastrointestinal injury in sepsis.

Effects of Sevoflurane Inhalation Anesthesia on the Intestinal Microbiome in Mice. Front Cell Infect Microbiol 2021; 11:633527. [PMID: 33816336 PMCID: PMC8012717 DOI: 10.3389/fcimb.2021.633527] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Accepted: 03/02/2021] [Indexed: 12/12/2022] Open
Abstract
In recent years, more and more attention has been paid to intestinal microbiome. Almost all operations will go through the anesthesia process, but it is not clear whether the intervention of anesthesia alone will affect the change in the intestinal microbiome. The purpose of this study was to verify the effect of sevoflurane inhalation anesthesia on the intestinal microbiome. The animal in the experimental group was used to provide sevoflurane inhalation anesthesia for 4 hours. The control group was not intervened. The feces of the experimental group and the control group were collected on the 1st, 3rd, 7th and 14th days after anesthesia. Sevoflurane inhalation anesthesia will cause changes in the intestinal microbiome of mice. It appears on the 1st day after anesthesia and is most obvious on the 7th day. The specific manifestation is that the abundance of microbiome and the diversity of the microbiome is reduced. At the same time, Untargeted metabonomics showed that compared with the control group, the experimental group had more increased metabolites related to the different microbiome, among which 5-methylthioadenosine was related to the central nervous system. Subsequently, the intestinal microbiome diversity of mice showed a trend of recovery on the 14th day. At the genus level, the fecal samples obtained on the 14th day after anesthesia exhibited significantly increased abundances of Bacteroides, Alloprevotella, and Akkermansia and significantly decreased abundances of Lactobacillus compared with the samples obtained on the 1st day after anesthesia. However, the abundance of differential bacteria did not recover with the changing trend of diversity. Therefore, we believe that sevoflurane inhalation anesthesia is associated with changes in the internal microbiome and metabolites, and this change may be completed through the brain-gut axis, while sevoflurane inhalation anesthesia may change the intestinal microbiome for as long as 14 days or longer.

Abstract
Previous studies have investigated the association between cognitive frailty and falls among older adults in community; however, no study investigated this relationship among older patients living in hospital. This study aimed to examine the relationship of cognitive frailty with falls among older inpatients in Chinese hospital. METHODS This analysis consisted of 9192 older inpatients aged 65 years or over from six hospitals in China. We used FRAIL scale and Mini-Cog to assess frailty and cognitive impairment, respectively. A generalized estimating equation was used to examine the relationship between cognitive frailty and falls at 30-day follow-up. RESULTS Among 9192 older inpatients enrolled in this present study, the mean (SD) age was 72.40(5.72) years, with 3850(41.88%) women. The cross-sectional analysis found that after controlling for variables (age, gender, education, depression, and hospital ward cluster effect), hospitalized patients with cognitive frailty, frailty only, or cognitive impairment only at baseline were all associated with history of falls (P<0.05). At 30-day follow-up, generalized estimating equation with full-adjustment showed that inpatients with cognitive frailty were at greater risk of falls than those of non-frail and cognitive intact (OR=3.0,95%CI:1.32-6.83). This association was also observed in individuals with frailty only (OR=2.11,95%CI:1.04-4.27) but not for patients with cognitive impairment only((OR=1.11,95%CI:0.43-2.85). CONCLUSION Our study suggested that hospitalized Chinese older adults with cognitive frailty were independently associated with falls. Early screening frailty and cognitive impairment were significant for older patients by clinicians, and corresponding interventions, exercise training and nutritional programs, should be implemented to prevent falls.

Effects of continuous intravenous infusion of propofol on intestinal flora in rats. Biomed Pharmacother 2020; 134:111080. [PMID: 33338744 DOI: 10.1016/j.biopha.2020.111080] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2020] [Revised: 11/19/2020] [Accepted: 11/28/2020] [Indexed: 12/18/2022] Open
Abstract
Under normal circumstances, the gut microbiota, host, and external environment establish a dynamic ecological balance and maintain human health. Once this balance is broken, the intestinal flora dysregulation will form, manifested by changes in the diversity, richness, proportion, location and biological characteristics of the gut microbiota. The hypothesis that propofol alters gut microbes was tested in a rat model with continuous intravenous infusion of propofol. Eight male wistar rats underwent tail vein puncture and catheterization respectively, and were continuously pumped with propofol for 3 h. Feces were collected from each rat before and on the 1 st, 3rd, 7th and 14th days after intervention. Finally, the effect of continuous intravenous infusion of propofol on the intestinal flora of rats was analyzed by high-throughput 16S rRNA gene amplification sequencing. Through high-throughput 16S rRNA gene amplicon sequencing analysis, we found that continuous intravenous infusion of propofol had little effect on intestinal flora in rats. Analysis of Alpha (shannon diversity index) showed that group A-7 was different from group P and group A-1 (P = 0.034), and recovered on the 14th day. Although the species diversity analysis showed a significant difference among the five groups (P = 0.049), the distribution of most fecal samples in the PCoA showed a clustered distribution, indicating similarity. In addition, no significant difference was found in the statistical KEGG difference pathway through LEfSe analysis.

Abstract
Abstract
Background
Stent overlap has been associated with adverse outcomes. However, data regarding the impact of new generations drug-eluting stents (DES) overlap in the context of ST-segment elevation myocardial infarction (STEMI) are limited.
Objective
To compare the 6-moth clinical outcomes of patients with and without new generations DES overlap implanted during primary PCI for anterior STEMI.
Methods
We evaluated a total of 1078 consecutive anterior STEMI patients who underwent primary PCI with deployment of new generations DES. The patients were divided according to the presence or absence of stent overlap into 2 groups; overlapping-stents group (n=388) and single-stent group (n=690). We compared the rates of cardiac mortality, major adverse cardiovascular events (MACEs; composite of death, reinfarction, ischemia-driven target vessel revascularization (TVR), definite stent thrombosis (ST), and stroke) between the 2 groups.
Results
There was a non-significant trend toward increased in-hospital mortality in the overlapping-stents group related to a significant higher rate of cardiogenic shock [9.5% versus 6.1%, respectively; P=0.037] and post-procedural suboptimal TIMI flow [26.3% versus 19.4%, respectively; P=0.009] as compared to the single-stent group. Yet, there were no significant differences between the 2 groups in the incidence of 6-month cardiac death: [18 (4.6%) and 21 (3%); P=0.173], MACEs: [35 (9%) and 49 (7.1%); P=0.259], reinfarction: [14 (3.6%) and 22 (3.2%); P=713], TVR: [17 (4.4%) and 28 (4.1%); P=0.799], and definite ST: [14 (3.6%) and 19 (2.8%); P=0.434], respectively.
Conclusion
The use of multiple overlapping new generations DES, if needed, is relatively safe and acceptable in the context of primary PCI for STEMI patients.

Abstract
OBJECTIVE The aim was to use a novel statistical test to predict the trend of subarachnoid hemorrhage (SAH) incidence in response to temperature change and demonstrate its delayed effect in a short hazard period. PATIENTS AND METHODS In a retrospective study, data collected between January 2005 and September 2019 were analyzed and 1682 consecutive SAH patients from one hospital were enrolled. Meteorological data in this period including temperature, atmospheric pressure, and humidity were obtained from the China Surface Meteorological Station. Using a case-crossover analysis and distributed lag linear model (DLM) with 4 days lag period to assess the association of temperature change from the previous day (TCP) and risk of SAH. Results were presented as overall cumulative odds ratios (ORs) and 95% CI. RESULTS Temperature decline was associated with increased risks of SAH: overall cumulative OR was 1.14 (95% CI: 1.05-1.23) for -1.1°C; 2.11 (95% CI: 1.37-3.25) for -6.2°C, as compared with a reference TCP of 0°C. Temperature decline on the day of SAH onset was significantly associated with SAH incidence days, ORs 1.34 (95% CI: 1.19-1.52). In addition, December, ORs 1.49 (95% CI: 1.17-1.90) in winter was the ictus peak in Rizhao throughout the year. CONCLUSIONS Temperature decline from the previous day is a trigger for the occurrence of SAH. Its effect was most apparent on the day of exposure.

Abstract
Abstract
Introduction
Emerging evidence suggests that disparities in sleep regularity, a marker of circadian disruption, contributes to hypertension disparities; however, data among African Americans are limited. We examined associations of sleep regularity and chronotype with hypertension among African Americans in the Jackson Heart Sleep Study (JHSS).
Methods
Participants underwent 7-day actigraphy, completed questionnaires, and had seated blood pressure (BP) measured as part of the JHSS (2012 - 2016). Sleep regularity was defined as the standard deviation (SD) of actigraphy-measured sleep onset timing or sleep duration. Chronotype was assessed by the Morningness-Eveningness Questionnaire. Prevalent hypertension was defined as either a systolic BP ≥ 130 mmHg or diastolic BP ≥ 80mmHg, antihypertensive medication use, or self-report of diagnosed hypertension. Multivariable logistic regression models were fit to estimate the prevalence odds ratio (OR) and 95% confidence intervals for the associations of hypertension with sleep regularity measures (SD of sleep onset timing and sleep duration) and chronotype adjusted for covariates.
Results
Participants (n=830) on average were 63.4 years (SD:10.7), mostly female (66.3%) and hypertensive (85.8%). Compared to individuals with sleep onset SD < 30 minutes, higher adjusted odds of hypertension was observed with increasing variability: OR:1.87 (CI:0.99-3.56); OR:2.16 (1.06-4.39), and OR:2.41 (1.12-5.20), for SD > 30 & ≤ 60, > 60 & ≤ 90 and > 90 minutes, respectively. Among non-shift workers, definite morning and evening types compared to intermediates had higher adjusted odds of hypertension, OR:1.71 (1.04-2.83) and OR:2.56 (1.12-5.84), respectively. There were no observed associations for the SD of sleep duration with hypertension.
Conclusion
Increased sleep onset variability and extreme chronotypes were associated with prevalent hypertension, supporting interventions targeting sleep hygiene recommendations promoting regular sleep. Future research is needed to understand sleep patterns and risk of cardiovascular disease according to chronotype.

Abstract
Harvesting uncapped immature honey (IMH) followed by dehydration is a typical counterfeit honey production process, but the differences between IMH and capped mature honey (MH) have not been well described previously. In this study, MH and IMH from Apis mellifera colonies during the same rapeseed flower season were compared. MH was found to have lower water content, lower acidity, and higher fructose content. High-performance liquid chromatography combined with quadrupole time-of-flight mass spectrometry-based untargeted metabolomic analysis indicated that MH had a distinct metabolite composition to IMH. Targeted metabolomic analysis on 20 major polyphenolic constituents showed higher accumulation in MH. MH had greater bacteriostatic effect and stronger free radical scavenging effect. While both the honeys mitigated cell damage caused by H2O2, the effective dosage of IMH was higher and its inducing effect on the antioxidant gene expression was weaker. Overall, MH was shown to be of better quality than IMH not only because of its richer polyphenolic composition but also because of its stronger biological activity.

Efficacy and safety of thromboprophylaxis in cancer patients: a systematic review and meta-analysis. Ther Adv Med Oncol 2020; 12:1758835920907540. [PMID: 32215058 PMCID: PMC7081475 DOI: 10.1177/1758835920907540] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Accepted: 01/20/2020] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Thrombosis is a common complication in patients with cancer. Whether thromboprophylaxis could benefit patients with cancer is unclear. The aim of this systematic review was to determine the efficacy and safety of thromboprophylaxis in patients with cancer undergoing surgery or chemotherapy. METHODS We searched the Cochrane Library, EMBASE, MEDLINE, EBSCOhost, and Web of Science for studies published before May 2018 to investigate whether thromboprophylaxis measures were more effective than a placebo in patients with cancer. RESULTS In total, 33 trials with 11,942 patients with cancer were identified. In patients with cancer undergoing surgery, the administration of thromboprophylaxis was associated with decreasing trends in venous thromboembolism (VTE) [relative risk (RR) 0.51, 95% confidence interval (CI) 0.32-0.81] and DVT (RR 0.53, 95% CI 0.33-0.87). In patients with cancer undergoing chemotherapy, the administration of thromboprophylaxis reduced the incidences of VTE, DVT, and pulmonary embolism compared with no thromboprophylaxis (RR 0.54, 95% CI 0.40-0.73; RR 0.47, 95% CI 0.31-0.73; RR 0.51, 95% CI 0.32-0.81, respectively). The pooled results regarding major bleeding showed no significant difference between prophylaxis and no prophylaxis in either the surgical or the chemotherapy groups (RR 2.35, 95% CI 0.74-7.52, p = 0.1482, I2 = 0%; RR 1.30, 95% CI 0.93-1.83, p = 0.1274, I2 = 0%, respectively). CONCLUSION Thromboprophylaxis did not increase major bleeding events or the incidence of thrombocytopenia. All-cause mortality was not significantly different between those who received thromboprophylaxis and those who did not. This meta-analysis provides evidence that thromboprophylaxis can reduce the number of VTE and DVT events, with no apparent increase in the incidence of major bleeding in patients with cancer.

Abstract
Objective: To investigate the clinicopathological features, immunophenotypes, genetics and prognosis of T-lymphocyte lymphoma/myeloid sarcoma combined with Langerhans cell histiocytyosis (coexistence of T-LBL/MS and LCH). Methods: Clinical and pathological data of the 6 patients with coexistence of T-LBL/MS and LCH were analyzed, who were diagnosed at the Foshan Hospital of Sun Yat-sen University and the Friendship Hospital of Capital Medical University, from December 2013 to April 2019. The hematoxylin and eosin stain, immunohitochemistry (EnVision) and in situ hybridization were used. Related literatures were reviewed. Results: Four patients were T-LBL combined with LCH, 1 was T-LBL/MS combined with LCH, and 1 was MS combined with LCH. There were 2 male and 4 female patients, with age ranged from 5 to 77 years old (median, 59 years old). Three patients represented with only multiple lymph node swelling. The other 3 displayed both multiple lymph node swelling, and skin/liver or spleen lesions. Lymph node structure was destroyed in 5 cases, while 3 cases had several residual atrophic follicles. Histologically, there were two types of tumor cells: one type of the abnormal lymphoid-cells exhibited small to medium-sized blast cells, typically showing a nested distribution, and these cells were mainly identified in residual follicles and paracortical areas; the other type of histiocytoid cells had a large cell size and abundant pale or dichromatic cytoplasm. Their nuclei were irregularly shaped, showing folded appearance and nuclear grooves. These cells were mainly present in marginal sinus, medullary sinus and interstitial area between follicles. Eosinophil infiltration in the background was not evident in any of the cases. The lymphoid-cells of medium size showed TdT+/CD99+/CD7+, with variable expression of CD34/MPO/CD2/CD3. Ki-67 index was mostly 30%-50%. However, the histiocytoid cells showed phenotype of CD1a+/S-100+/Langerin+/-, while CD163/CD68 were positive in some degree. These cells did not express any T or B cell markers. The Ki-67 index mostly ranged between 10%-20%. None of the cases had Epstin-Barr viral infection. Among the 6 patients, 4 patients were followed up (6-63 months, median time, 18.5 months), of whom 1 patient died of the disease and 3 patients were alive at the end of follow-up. Conclusions: T-LBL/MS combined with LCH is a rare mixed type of immature hematopoietic disease, and mainly occurs in lymph node and skin. The clinical course is overall aggressive. Therefore, it is helpful to recognize and identify the two pathologic components in the same tissue for accurate diagnosis and proper treatment.

Abstract
BACKGROUND To evaluate whether the level of myeloid-derived suppressor cells is related to the complication of sepsis after esophageal cancer surgery and whether changing the myeloid-derived suppressor cells levels can improve the prognosis of patients cancer-related sepsis. METHODS A total of 178 esophageal cancer patients from Harbin Medical University Cancer Hospital were included in this study. Blood samples were taken from the patients for the analysis of the levels of G-MDSCs and M-MDSCs by flow cytometry. The conditions of the patients was recorded. Male C57BL/6 mice were implanted with Lewis lung cancer cells (2 × 106/mice) by subcutaneous injection into the iliac fossa. Three weeks later, we performed CLP in the mice. All-trans-retinoic acid (ATRA) was intraperitoneally injected at 20 mg/kg, and the control group was injected with 0.9 % NS. We observed the mortality of the mice with cancer-related sepsis. RESULTS In all, 95 % of the esophageal cancer patients had a high level of G-MDSCs (>50 %). A high level of G-MDSCs (>82.5 %) can lead to high morbidity from sepsis after surgery. The increase in M-MDSCs was suggestive of a poor prognosis in patients with cancer-related sepsis. ATRA can improve the survival of patients with cancer-related sepsis. CONCLUSIONS A high level of G-MDSCs can be used to determine the incidence of sepsis in preoperative esophageal cancer patients, M-MDSCs might be effective prognostic indicators for cancer-sepsis patients, and changing the MDSC levels can improve the mortality of patients with cancer-related sepsis.

Abstract
Objective: To investigate the expression of myocyte enhancer factor 2B (MEF2B) in mantle cell lymphomas (MCL), and to analyze the correlation between the expression of MEF2B and pathological subtypes, structural subtypes, SOX11 expression and its clinical significance. Methods: Paraffin-embedded tissues were stained with HE, immunohistochemistry (EnVision method) and fluorescence in situ hybridization (FISH) , in addition, the clinical and pathological data of 60 cases of MCL were collected at Sun Yat-sen University Foshan Hospital and Sun Yat-sen University Cancer Center from January,2002 to May, 2019 for analysis. Results: Of the 60 MCLs, males is predominant (M∶F=3∶1). Histologically, the typical MCL is the majority (classical MCL: variant type MCL=48 cases:12 cases) . Fifty cases were classified into non-complete FDC meshwork type MCL, and the remaining 10 cases were classified into the complete-FDC meshwork type MCL group. Patients with classical MCL were more than 60 years old. The coexistent lesion sites both node and extranode in pathological subtype or structural subtype was the most common lesion sites. SOX11(+) MCL was common in classical MCL (P=0.040) and tended to be complete-FDC meshwork type MCL (P=0.086). The expression rate of MEF2B in MCL was 60.0%(36/60). This rate of MEF2B in classical type, complete-FDC meshwork type and SOX11(+) MCL was significantly higher than that variant type, no complete-FDC meshwork type, SOX11(-)MCL (P<0.05), respectively. There was no difference in clinical characteristics of MCL between MEF2B positive and negative groups. Compared with SOX11(-)MCL, the percentage of MEF2B expressed in tumor cells of SOX11(+)MCL was significantly higher (P=0.027). The expression of MEF2B was not related to the proliferation of tumor cells (P=0.341). There was no significant difference in the survival rate between different expression groups of MEF2B and SOX11 (P=0.304 and P=0.819, respectively). Only the mortality of variant type (blastoid/pleomorphic) MCL within 2 years was significantly higher than that of classical type MCL (P<0.05). Conclusions: The expression of MEF2B in MCL is related to the pathological subtypes, structural subtypes and the expression of SOX11, but not to the proliferation and prognosis. The high mortality rate within 2 years is only found in variant MCL. However, the role of MEF2B in MCL needs to be further studied.

Abstract
OBJECTIVE To explore the significance of IL28RA in diagnosis of early pancreatic cancer and its regulation to pancreatic cancer cells by the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway. PATIENTS AND METHODS A total of 81 patients with early pancreatic cancer were enrolled as a pancreatic cancer group, and 81 patients with benign pancreatic diseases were enrolled as a benign disease group. Western blot was adopted to analyze the serum IL28RA expression of the two groups and its diagnostic value in early pancreatic cancer. A pancreatic cancer cell model was constructed, and the IL28RA expression in pancreatic cancer cells, PANC-1 and BXPC-3, was up-regulated to explore the biological function of pancreatic cancer cells after up-regulation of IL28RA and the effects on JAK-STAT signaling pathway. RESULTS Lowly expressed in serum of patients with pancreatic cancer, IL28RA showed a sensitivity of 80.25%, specificity of 75.31%, and area under the curve (AUC) of 0.846 in diagnosis of early pancreatic cancer. It was found that up-regulation of IL28RA expression in pancreatic cancer cells inhibited proliferation and invasion abilities of pancreatic cancer cells, increased apoptosis rate and expression of pro-apoptotic protein bax, decreased expression of anti-apoptosis protein bcl-2, and significantly inhibited phosphorylation level of JAK2 and STAT3 proteins. CONCLUSIONS IL28RA is lowly expressed in pancreatic cancer patients, and has certain diagnostic value for early pancreatic cancer. Its up-regulated expression can inhibit the proliferation and invasion of pancreatic cancer cells, and promote their apoptosis by inhibiting the activation of JAK-STAT signaling pathway.

Long non-coding RNA HULC promotes proliferation and osteogenic differentiation of bone mesenchymal stem cells via down-regulation of miR-195. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2019; 22:2954-2965.

Abstract
OBJECTIVE LncRNAs HULC has been reported to be important regulators in the development of various human diseases. However, the role of HULC in bone mesenchymal stem cells (BMSCs) remains unclear. The present study aimed to explore the regulatory effect of HULC on proliferation and osteogenic differentiation of BMSCs and the underlying mechanism. MATERIALS AND METHODS The expression of HULC and miR-195 in BMSCs were altered by transfection and measured by qRT-PCR. Cell viability was measured by the CCK-8 assay. Osteogenic differentiation of BMSCs was determined by evaluation of osteogenic markers (Ocn, ALP, Runx2, and Col-1) expression levels using Western blot and qRT-PCR. Furthermore, Western blot was performed to assess the expression of proliferation-related factors, Wnt/β-catenin and p38MAPK pathway-related factors. RESULTS HULC overexpression significantly increased cell viability, down-regulated p21 expression but up-regulated CyclinD1 expression, and promoted the levels of osteogenic markers. However, the complete opposite effect was observed in HULC knockdown. Notably, miR-195 expression was negatively regulated by HULC and miR-195 exerted a reversed effect of HULC on BMSCs. Moreover, miR-195 mediated the regulatory effect of HULC on BMSCs proliferation and osteogenic differentiation, as miR-195 mimic abolished the effect of HULC overexpression on BMSCs. We also found that HULC overexpression enhanced the activation of Wnt/β-catenin and p38MAPK pathway through down-regulating miR-195. CONCLUSIONS We revealed that HULC promoted proliferation and osteogenic differentiation of BMSCs. The potential mechanism might be involved in its negative regulation on miR-195 and enhanced activation of Wnt/β-catenin and p38MAPK pathway.

Effects of Immunonutrition on Chemoradiotherapy Patients: A Systematic Review and Meta-Analysis. JPEN J Parenter Enteral Nutr 2019; 44:768-778. [PMID: 31709589 DOI: 10.1002/jpen.1735] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2019] [Revised: 09/26/2019] [Accepted: 10/15/2019] [Indexed: 01/19/2023]
Abstract
OBJECTIVE We conducted a systematic review to assess the effects of immunonutrition on chemoradiotherapy patients. METHODS We searched the Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, CINAHL, and the Web of Science. We assessed the risk of bias using the Cochrane Risk of Bias tool. Our primary outcomes were the incidence of oral mucositis and diarrhea. The secondary outcomes were the incidence of esophagitis, grade ≥3 oral mucositis, grade ≥3 diarrhea, grade ≥3 esophagitis, and body weight loss. RESULTS A total of 1478 patients and 27 studies were included. There were no significant differences in the incidence of oral mucositis (relative risk [RR] = 0.91; 95% confidence interval [CI], 0.79-1.05), diarrhea (RR = 0.89; 95% CI, 0.76-1.05), or esophagitis (RR = 0.55; 95% CI, 0.11-2.86) between the immunonutrition group and standard nutrition/placebo group. Nevertheless, immunonutrition significantly reduced the incidence of grade ≥3 oral mucositis (RR = 0.45; 95% CI, 0.22-0.92), grade ≥3 diarrhea (RR = 0.56; 95% CI, 0.35-0.88), grade ≥3 esophagitis (RR = 0.15; 95% CI, 0.04-0.54), and losing >5% body weight (RR = 0.34; 95% CI, 0.18-0.64). CONCLUSIONS In this study, immunonutrition failed to reduce the incidence rates of oral mucositis, diarrhea, or esophagitis but was conducive to significantly improving the severity of oral mucositis and diarrhea esophagitis and reducing the rate of body weight loss.

Immunonutrition vs Standard Nutrition for Cancer Patients: A Systematic Review and Meta-Analysis (Part 1). JPEN J Parenter Enteral Nutr 2019; 44:742-767. [PMID: 31709584 DOI: 10.1002/jpen.1736] [Citation(s) in RCA: 40] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2018] [Revised: 09/28/2019] [Accepted: 10/15/2019] [Indexed: 01/08/2023]
Abstract
The aim of this study was to determine the efficacy of immunonutrition vs standard nutrition in cancer patients treated with surgery. Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, EBSCOhost, and Web of Science were searched. Sixty-one randomized controlled trials were included. Immunonutrition was associated with a significantly reduced risk of postoperative infectious complications (risk ratio [RR] 0.71 [95% CI, 0.64-0.79]), including a reduced risk of wound infection (RR 0.72 [95% CI, 0.60-0.87]), respiratory tract infection (RR 0.70 [95% CI, 0.59-0.84]), and urinary tract infection (RR 0.69 [95% CI, 0.51-0.94]) as well as a decreased risk of anastomotic leakage (RR 0.70 [95% CI, 0.53-0.91]) and a reduced hospital stay (MD -2.12 days [95% CI -2.72 to -1.52]). No differences were found between the 2 groups with regard to sepsis or all-cause mortality. Subgroup analyses revealed that receiving arginine + nucleotides + ω-3 fatty acids and receiving enteral immunonutrition reduced the rates of wound infection and respiratory tract infection. The application of immunonutrition at 25-30 kcal/kg/d for 5-7 days reduced the rate of respiratory tract infection. Perioperative immunonutrition reduced the rate of wound infection. For malnourished patients, immunonutrition shortened the hospitalization time. Therefore, immunonutrition reduces postoperative infection complications and shortens hospital stays but does not reduce all-cause mortality. Patients who are malnourished before surgery who receive arginine + nucleotides + ω-3 fatty acids (25-30 kcal/kg/d) via the gastrointestinal tract during the perioperative period (5-7 days) may show better clinical efficacy.

Generation of a Primary Hyperoxaluria Type 1 Disease Model Via CRISPR/Cas9 System in Rats. Curr Mol Med 2019; 18:436-447. [PMID: 30539697 DOI: 10.2174/1566524019666181212092440] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2018] [Revised: 10/27/2018] [Accepted: 10/31/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND Primary hyperoxaluria type 1 (PH1) is an inherited disease caused by mutations in alanine-glyoxylate aminotransferase (AGXT). It is characterized by abnormal metabolism of glyoxylic acid in the liver leading to endogenous oxalate overproduction and deposition of oxalate in multiple organs, mainly the kidney. Patients of PH1 often suffer from recurrent urinary tract stones, and finally renal failure. There is no effective treatment other than combined liver-kidney transplantation. METHODS Microinjection was administered to PH1 rats. Urine samples were collected for urine analysis. Kidney tissues were for Western blotting, quantitative PCR, AGT assays and histological evaluation. RESULTS In this study, we generated a novel PH1 disease model through CRISPR/Cas9 mediated disruption of mitochondrial localized Agxt gene isoform in rats. Agxt-deficient rats excreted more oxalate in the urine than WT animals. Meanwhile, mutant rats exhibited crystalluria and showed a slight dilatation of renal tubules with mild fibrosis in the kidney. When supplied with 0.4% ethylene glycol (EG) in drinking water, mutant rats excreted greater abundance of oxalate and developed severe nephrocalcinosis in contrast to WT animals. Significantly elevated expression of inflammation- and fibrosisrelated genes was also detected in mutants. CONCLUSION These data suggest that Agxt-deficiency in mitochondria impairs glyoxylic acid metabolism and leads to PH1 in rats. This rat strain would not only be a useful model for the study of the pathogenesis and pathology of PH1 but also a valuable tool for the development and evaluation of innovative drugs and therapeutics.
