RESUMEN

The endothelial glycocalyx is damaged in postcardiac arrest syndrome (PCAS), but the prognostic value is unknown. We aimed to observe the expression and prognostic value of glycocalyx shedding products, including syndecan-1 (SDC-1), hyaluronan (HA), and heparan sulfate (HS) in PCAS. Data on clinical and 28-day outcomes of seventy-one consecutive patients with out-of-hospital cardiac arrest (OHCA) after the return of spontaneous circulation (ROSC) were collected. SDC-1, HA, and HS were measured on days 0, 1, and 3 after ROSC. Thirty healthy individuals were controls. Glycocalyx shedding was observed in human umbilical vein endothelial cells (HUVECs) stimulated during hypoxia and reoxygenation in vitro. Within 4 h of ROSC, SDC-1 and HA levels, significantly increased. In the 28-day non-survivors, HA levels showed a gradual upward trend, SDC-1 remained at a high level, and HS levels first increased, then decreased. Kaplan-Meier curves and binary logistic regression analysis showed the prognostic value of SDC-1 levels on days 0, 1, and 3, HA levels on days 1 and 3, and HS levels on day 1. Only HS levels on day 1 showed a prognostic value for 28-day neurological outcomes. SDC-1 and HA levels were positively correlated with the no-flow time. In vitro, HUVECs showed shedding of SDC-1 and HS during a prolonged duration of hypoxia. After ROSC, SDC-1, HA, and HS levels may predict the 28-day survival after PCAS, and HS levels are associated with functional outcomes.

RESUMEN

In bone tissue engineering, the bone immunomodulatory properties of biomaterials are critical for bone regeneration, which is a synergistic process involving physiological activities like immune response, osteogenesis, and angiogenesis. The effect of the macrophage immune microenvironment on the osteogenesis and angiogenesis of various material extracts was examined in this experiment using Mg2+and Nano-hydroxyapatite/collagen (nHAC) in both a single application and a combined form. This studyin vitrorevealed that the two compounds combined significantly inhibited the NF-κB signaling pathway and reduced the release of inflammatory factors from macrophages when compared with the extraction phase alone. Additionally, by contributing to the polarization of macrophages towards the M2 type, the combined effects of the two materials can significantly improve osteogenesis/angiogenesis. The results ofin vivoexperiments confirmed that Mg2+/nHAC significantly promoted bone regeneration and angiogenesis. This study offers a promising method for enhancing bone graft material osseointegration.

RESUMEN

OBJECTIVE: To determine the relationship between use of nebulized heparin and clinical outcomes in mechanically ventilated patients. METHODS: The Medline, Embase, Web of Science, Cochrane Library, and PubMed databases were searched for relevant randomized controlled trials (RCTs), published between database inception and May 2022. Primary outcomes were intensive care unit (ICU) length of stay and in-hospital mortality; secondary outcomes included duration of mechanical ventilation, ventilator-free days (VFDs) in 28 days, and length of hospitalization. The study protocol was registered on PROSPERO (registration No: CRD42022345533). RESULTS: A total of eight RCTs (651 patients) were included. Nebulized heparin was associated with reduced ICU length of stay (six studies; mean difference [MD] -1.10, 95% confidence interval [CI] -1.87, -0.33, I2 = 76%), reduced duration of mechanical ventilation (two studies; MD -2.63, 95% CI -3.68, -1.58, I2 = 92%) and increased VFDs in 28 days (two studies; MD 4.22, 95% CI 1.10, 7.35, I2 = 18%), without increased incidence of adverse events, such as bleeding; but was not associated with a reduction in length of hospitalization (three studies; MD -1.00, 95% CI -2.90, -0.90, I2 = 0%) or in-hospital mortality (five studies; odds ratio 1.10, 95% CI 0.69, 1.77, I2 = 0%). CONCLUSION: Nebulized heparin reduces ICU length of stay and duration of mechanical ventilation in mechanically ventilated patients, but has no effect on length of hospitalization or mortality.

RESUMEN

Background and Aims: Tenofovir amibufenamide (TMF) is a novel phosphoramidated prodrug of tenofovir with noninferior efficacy and better bone and renal safety to tenofovir disoproxil fumarate (TDF) in 48 weeks of treatment. Here, we update 96-week comparison results. Methods: Patients with chronic hepatitis B were assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks. The virological suppression was defined as HBV DNA levels <20 IU/mL at week 96. Safety was evaluated thoroughly with focusing on bone, renal, and metabolic parameters. Results: Virological suppression rates at week 96 were similar between TMF and TDF group in both HBeAg-positive and HBeAg-negative populations. Noninferior efficacy was maintained in the pooled population, while it was first achieved in patients with HBV DNA ≥7 or 8 log10 IU/mL at baseline. Non-indexed estimated glomerular filtration rate for renal safety assessment was adopted, while a smaller decline of which was seen in the TMF group than in the TDF group (p=0.01). For bone mineral density, patients receiving TMF displayed significantly lower reduction levels in the densities of spine, hip, and femur neck at week 96 than those receiving TDF. In addition, the lipid parameters were stable after week 48 in all groups while weight change still showed the opposite trend. Conclusions: TMF maintained similar efficacy at week 96 compared with TDF with continued superior bone and renal safety profiles (NCT03903796).

RESUMEN

Previous studies have found that negative parental rearing styles can negatively predict the acquisition of ego identity, while it has not been discussed whether the overcompetitive attitudes, a stable personality, will further hinder their ego identity development under the model of educational involutionary. The study used the Overcompetitive Attitude Scale, the Brief Parental Rearing Styles Questionnaire, and the Ego Identity Status Scale to investigate 550 young students in a school in Suzhou in order to explore the influence of parental rearing styles on adolescents' ego identity development and the role of involutional attitudes. The results showed that: (1) Adolescents' overcompetitive attitude was positively predicted by parental rejection and overprotection, while it was negatively predicted by parental emotional warmth. (2) Parental emotional warmth significantly predicted adolescents' ego identity status more favorably than parental rejection, overprotection, and overcompetitive attitude. (3) Overcompetitive attitude plays a partial intermediary role between parental rearing style and ego identity.

RESUMEN

OBJECTIVE: HS-20090 is a proposed biosimilar candidate of Denosumab (Xgeva®). The study aimed to evaluate the similarity of pharmacokinetics (PK), pharmacodynamics (PD), safety, and immunogenicity between HS-20090 and Xgeva® in healthy Chinese subjects. METHODS: A single-center, randomized, double-blinded, active-controlled study was conducted in healthy Chinese adult male subjects. A total of 154 subjects were planned to be randomly assigned (1:1) to receive 120 mg of either HS-20090 or Xgeva® in a single subcutaneous injection, with a follow-up period of 155 days. The primary objective was to evaluate the bioequivalence of PK. The primary endpoints were Cmax and AUC0-∞. The secondary objectives were to evaluate the similarity of PD, safety, and immunogenicity. RESULTS: All 154 subjects were included in the PK, PD, and safety analyses. The 90% CIs of GMRs of HS-20090/Xgeva® for Cmax, AUC0-t, and AUC0-∞ were 90.49 ~ 100.23%, 94.45 ~ 104.61%, and 94.08 ~ 105.23%, respectively, achieving the bioequivalence criteria of 80 ~ 125%. The PD parameters and incidence of adverse events between HS-20090 and denosumab were also similar, with no detection of ADA in both the groups. CONCLUSION: HS-20090 was highly similar to Xgeva®, with regard to PK, PD, safety profiles, and immunogenicity in healthy Chinese subjects. These data support subsequently comparative clinical study for bone metastases in solid tumors. CLINICAL TRIAL REGISTRATION: www.clinicaltrials.gov identifier is NCT04494373.

RESUMEN

INTRODUCTION: Aumolertinib (formerly almonertinib; HS-10296) is a novel third-generation EGFR tyrosine kinase inhibitor (TKI) with revealed activity against EGFR-sensitizing mutations and EGFR T790M mutation. METHODS: Patients with locally advanced or metastatic NSCLC who developed an EGFR T790M mutation after progression on first- or second-generation EGFR TKI therapy were enrolled in this registrational phase 2 trial of aumolertinib at 110 mg orally once daily (NCT02981108). The primary end point was objective response rate (ORR) by independent central review. RESULTS: A total of 244 patients with EGFR T790M-positive NSCLC were enrolled. The ORR by independent central review was 68.9% (95% confidence interval [CI]: 62.6-74.6). The disease control rate was 93.4% (95% CI: 89.6-96.2). The median duration of response was 15.1 months (95% CI: 12.5-16.6). The median progression-free survival was 12.4 months (95% CI: 9.7-15.0). Among 23 patients with assessable central nervous system (CNS) metastases, the CNS-ORR and CNS-disease control rate were 60.9% (95% CI: 38.5-80.3) and 91.3% (95% CI: 72.0-98.9), respectively. The median CNS-duration of response was 12.5 months (95% CI: 5.6-not reached). Treatment-related adverse events of more than or equal to grade 3 occurred in 16.4% of the patients, with the most common being increased blood creatine phosphokinase level (7%) and increased alanine aminotransferase level (1.2%). The relative dose density of aumolertinib was 99.2% in this study. CONCLUSIONS: Aumolertinib is an effective and well-tolerated third-generation EGFR TKI for patients with EGFR T790M-positive advanced NSCLC after disease progression on first- and second-generation EGFR TKI therapy. On the basis of these findings, aumolertinib was approved in the People's Republic of China for patients positive for EGFR T790M NSCLC.

RESUMEN

BACKGROUND: Tenofovir amibufenamide (TMF) can provide more efficient delivery than tenofovir disoproxil fumarate (TDF). AIM: To compare the efficacy and safety of TMF and TDF for 48 weeks in patients with chronic hepatitis B (CHB). METHODS: We performed a randomised, double-blind, non-inferiority study at 49 sites in China. Patients with CHB were assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo. The primary efficacy endpoint was the proportion of patients with hepatitis B virus (HBV) DNA less than 20 IU/mL at week 48. We also assessed safety, particularly bone, renal and metabolic abnormalities. RESULTS: We randomised 1002 eligible patients. The baseline characteristics were well balanced between groups. After a median 48 weeks of treatment, the non-inferiority criterion was met in all analysis sets. In the HBeAg-positive population, 50.2% of patients receiving TMF and 53.7% receiving TDF achieved HBV DNA less than 20 IU/mL. In the HBeAg-negative population, 88.9% and 87.8%, respectively, achieved HBV DNA less than 20 IU/mL in the TMF and TDF groups. Patients receiving TMF had significantly less decrease in bone mineral density at both hip (P < 0.001) and spine (P < 0.001), and a smaller increase in serum creatinine at week 48 (P < 0.05). Other safety results were similar between groups. CONCLUSION: TMF was non-inferior to TDF in terms of anti-HBV efficacy and showed better bone and renal safety. (NCT03903796).

RESUMEN

Total twenty-five 7-formyl-naphthyridyl-urea derivatives were designed, synthesized and evaluated for their inhibition of FGFR4 kinase and antitumor activity. The pharmacological data indicated that most of the tested compounds showed high selectivity towards FGFR4 kinase and could significantly inhibit FGFR4 and the tumor cells lines with the high expression of FGFR4. In particular, compounds 6f, 6g, 6h, 6l, 6m and 6s showed a good performance in pharmacokinetic tests. When tested in mice, the representative compound 6f was found to have good pharmacokinetic parameters, low toxicity, and better tumor inhibiting activity in vivo.

RESUMEN

Previous studies have examined the neural correlates of emotion regulation and the neural changes that are evoked by music exposure. However, the link between music and emotion regulation is poorly understood. The objectives of this review are to (1) synthesize what is known about the neural correlates of emotion regulation and music-evoked emotions, and (2) consider the possibility of therapeutic effects of music on emotion dysregulation. Music-evoked emotions can modulate activities in both cortical and subcortical systems, and across cortical-subcortical networks. Functions within these networks are integral to generation and regulation of emotions. Since dysfunction in these networks are observed in numerous psychiatric disorders, a better understanding of neural correlates of music exposure may lead to more systematic and effective use of music therapy in emotion dysregulation.

RESUMEN

OBJECTIVE: Emerging evidence has showed that interleukin-18 (IL-8) promoter polymorphisms and plasma IL-18 levels may be associated with increased risk of periodontitis, but individually published results are inconclusive. The aim of this meta-analysis was to derive a more precise estimation of these associations. METHODS: A literature search of PubMed, Cochrane Library, Embase, Web of Science, SpringerLink, China BioMedicine and China National Knowledge Infrastructure databases was conducted on articles published before April 1st, 2013. Crude odds ratio (OR) or standardized mean difference (SMD) with 95 % confidence intervals (CI) were calculated. RESULTS: Nine case-control studies were included with a total of 576 periodontitis patients and 458 healthy controls. Two common polymorphisms (-607A > C and -137G>C) in the IL-18 gene were addressed. Our meta-analysis results indicated that the C variant of IL-18 -607A>C polymorphism was associated with increased periodontitis risk (C allele vs. A allele: OR = 1.86, 95 % CI: 1.30-2.65, P = 0.001; AC+CC vs. AA: OR = 2.64, 95 % CI: 1.34-5.21, P = 0.005). There was also a significant association between the C variant of IL-18 -137G>C polymorphism and an increased periodontitis risk (C allele vs. G allele: OR = 1.47, 95 % CI: 1.13-1.91, P = 0.004; GC+CC vs. GG: OR = 1.66, 95 % CI: 1.21-2.29, P = 0.002). Furthermore, the mean levels of plasma IL-18 of periodontitis patients were also higher than those of healthy controls (SMD = 1.18, 95 % CI: 0.51-1.85, P = 0.001). CONCLUSION: The current meta-analysis suggests that IL-18 promoter polymorphisms and plasma IL-18 levels are associated with increased risk of periodontitis. IL-18 promoter polymorphisms and elevated plasma IL-18 levels may be useful biomarkers for predicting the development of periodontitis.
