RESUMO

PURPOSE: To explore symptom clusters and interrelationships using a network analysis approach among symptoms in patients with lung tumors who underwent computed tomography (CT)-guided microwave ablation (MWA). METHODS: A longitudinal study was conducted, and 196 lung tumor patients undergoing MWA were recruited and were measured at 24 h, 48 h, and 72 h after MWA. The Chinese version of the MD Anderson Symptom Inventory and the Revised Lung Cancer Module were used to evaluate symptoms. Network analyses were performed to explore the symptom clusters and interrelationships among symptoms. RESULTS: Four stable symptom communities were identified within the networks. Distress, weight loss, and chest tightness were the central symptoms. Distress, and weight loss were also the most key bridge symptoms, followed by cough. Three symptom networks were temporally stable in terms of symptom centrality, global connectivity, and network structure. CONCLUSION: Our findings identified the central symptoms, bridge symptoms, and the stability of symptom networks of patients with lung tumors after MWA. These network results will have important implications for future targeted symptom management intervention development. Future research should focus on developing precise interventions for targeting central symptoms and bridge symptoms to promote patients' health.

RESUMO

INTRODUCTION AND OBJECTIVE: Constipation is a common complication following spinal surgery that can result in distension, abdominal pain, infection, and even intestinal perforation. This study reports on an evidence-based implementation project to reduce the incidence of constipation in spinal surgery wards. METHODS: The project was conducted in the spinal surgery ward of a general tertiary hospital in Changsha City, China, from March to August 2022. We used the JBI Implementation Framework and the JBI Model of Evidence-Based Healthcare for audits and feedback. Data were collected and analyzed using JBI's Practical Application of Clinical Evidence System (PACES) software. Seven audit criteria were developed based on the best practice recommendations summarized by JBI. A baseline audit was conducted with 20 nurses and 50 patients in the spinal surgery ward, and a follow-up audit was conducted using the same sample size and setting. RESULTS: The baseline audit revealed compliance below 46% for five of the seven criteria. Strategies developed to address poor compliance included educating nurses and patients, developing a post-operative constipation risk assessment sheet, organizing stakeholder focus group meetings, establishing a constipation management routine, and effective empowerment of nurses. The follow-up audit showed positive compliance results, with the highest rate for Criterion 7 (100%) and the greatest increase for Criterion 2 (from 0% to 78%). Furthermore, the incidence of post-operative constipation decreased from 48% to 16%. CONCLUSION: The project improved compliance with audit criteria, reduced the incidence of constipation, and enhanced the efficiency of quality management in the spinal surgery ward.

RESUMO

Inflammation contributes to development of idiopathic pulmonary arterial hypertension (IPAH), and tumor biomarkers can reflect inflammatory and immune status. We aimed to determine the value of tumor biomarkers in IPAH comprehensively. We enrolled 315 patients with IPAH retrospectively. Tumor biomarkers were correlated with established indicators of pulmonary hypertension severity. Multivariable Cox regression found that AFP (hazard ratio [HR]: 1.587, 95% confidence interval [CI]: 1.014-2.482, p = 0.043) and CA125 (HR: 2.018, 95% CI: 1.163-3.504, p = 0.013) could independently predict prognosis of IPAH. The changes of AFP over time were associated with prognosis of patients, each 1 ng/mL increase in AFP was associated with 5.4% increased risk of clinical worsening (HR: 1.054, 95% CI: 1.001-1.110, p = 0.046), enabling detection of disease progression. Moreover, beyond well-validated PH biomarkers, CA125 was still of prognostic value in the low-risk patients (HR: 1.014, 95% CI: 1.004-1.024, p = 0.004), allowing for more accurate risk stratification and prediction of disease outcomes. AFP and CA125 can serve for prognosis prediction, risk stratification, and dynamic monitor in patients with IPAH.

RESUMO

BACKGROUND: The immune reconstitution after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is crucial for preventing infections and relapse and enhancing graft-versus-tumor effects. B cells play an important role in humoral immunity and immune regulation, but their reconstitution after allo-HSCT has not been well studied. METHODS: In this study, we analyzed the dynamics of B cells in 252 patients who underwent allo-HSCT for 2 years and assessed the impact of factors on B-cell reconstitution and their correlations with survival outcomes, as well as the development stages of B cells in the bone marrow and the subsets in the peripheral blood. RESULTS: We found that the B-cell reconstitution in the bone marrow was consistent with the peripheral blood (p = 0.232). B-cell reconstitution was delayed by the male gender, age >50, older donor age, the occurrence of chronic and acute graft-versus-host disease, and the infections of fungi and cytomegalovirus. The survival analysis revealed that patients with lower B cells had higher risks of death and relapse. More importantly, we used propensity score matching to obtain the conclusion that post-1-year B-cell reconstitution is better in females. Meanwhile, using mediation analysis, we proposed the age-B cells-survival axis and found that B-cell reconstitution at month 12 posttransplant mediated the effect of age on patient survival (p = 0.013). We also found that younger patients showed more immature B cells in the bone marrow after transplantation (p = 0.037). CONCLUSION: Our findings provide valuable insights for optimizing the management of B-cell reconstitution and improving the efficacy and safety of allo-HSCT.

RESUMO

Porcine reproductive and respiratory syndrome (PRRS) is a highly contagious and pathogenic infectious disease caused by the porcine reproductive and respiratory syndrome virus (PRRSV). It manifests as reproductive disorders in sows and respiratory disorders in piglets. PRRSV infects swine herds with symptoms such as abortions, stillbirths, and mummified fetuses in gestating sows. Piglets mainly experience abdominal respiration and respiratory symptoms. To date, the prevention of PRRS relies primarily on vaccination and the implementation of various preventive and control measures. Swine deaths caused by PRRS have resulted in significant economic losses to the pig industry worldwide. Non-structural protein 10 (NSP10) has helicase and adenosine triphosphatase (ATPase) activities that unwind DNA and RNA and play important roles in viral replication and transcription. Hence, it can be potentially used to develop novel reagents for the detection of PPRSV. This article reviews genetic variations, interaction with viral and host proteins, effects on PRRSV replication, immunomodulation, apoptosis, and viral virulence of NSP10, with the aim of providing a theoretical basis for the prevention and control of PRRS and drug development in the future.

RESUMO

As significant phytoalexins, stilbene compounds can improve the stress resistance of grapes under biotic and abiotic stress conditions and have biological effects such as antitumour, antioxidant, immune regulation and cardiovascular protection activities in humans. RESVERATROL SYNTHASE (RS), also known as STILBENE SYNTHASE (STS), is the critical enzyme regulating stilbene synthesis and has been identified in a few plant species. However, the regulatory mechanisms of stilbene synthesis are uncertain. In this study, an NAC family transcription factor from Vitis quinquangularis, named VqNAC44, was characterized as an indirect regulator of stilbene synthesis. It is worth noting that VqNAC44 did not bind to the STS promoter nor did it interact with the STS protein but interacted with the MYB transcription factor VqMYB15. This interaction between VqMYB15 and VqNAC44 was validated by a yeast two-hybrid assay and bimolecular fluorescence complementation. Overexpressing VqNAC44 in Arabidopsis thaliana significantly increased its tolerance to biotic and abiotic stresses. Transient overexpression of VqNAC44 and VqMYB15 in grape leaves resulted in increased expression of the STS gene and increased production of stilbene compounds. The experimental results confirmed that VqNAC44 regulated stilbene synthesis by interacting with VqMYB15, thereby enhancing the plant stress resistance.

RESUMO

BACKGROUND: Houttuynia Cordata Thunb. (H. cordata; Saururaceae) is a medicine food homology plant that is grown in many Asian countries. Its main phytochemical constituents are volatile oils, flavonoids, polysaccharides and alkaloids. It has considerable clinical applications and health benefits. PURPOSE: This paper reviews the existing literatures and patents, summarizes the phytochemistry, pharmacological activity, safety and economic botanical applications of H. cordata, and provides a reference for systematic study of the pharmacological effects of H. cordata, improvement of quality standards and further development of its medicinal resources. METHODS: A comprehensive search of literature and patents on H. cordata and its active ingredients published before June 2023 was conducted using PubMed, Google Scholar, Web of Science, and China Knowledge Network. RESULTS: H. cordata is not only edible and medicinal but also used in various aspects of daily life such as fermented beverages, nutraceuticals, feed and cosmetics. The main phytochemical constituents of H. cordata are volatile oils, flavonoids, organic acids and alkaloids. Several in vitro and in vivo studies and clinical trials have found that H. cordata extracts possess antioxidant, anti-inflammatory, antitumor, antibacterial, hepatoprotective and renal, immunomodulatory and potent antiviral effects. The mechanisms of expression of these pharmacological effects are related to the blood-brain barrier, lipophilicity, cAMP signaling and skin permeability, including blocking the MAPK signaling pathway, inhibiting the secretion of inflammatory factors such as TNF-α and IL-1ß, and activating the AMPK pathway. CONCLUSION: This paper provides a comprehensive review of the progress of research on the traditional applications, botany, chemical composition, pharmacological effects and safety of H. cordata and discusses for the first time the economic botanical aspects, which were not explored in the previous reviews. H. cordata has a wide range of bioactive substances whose therapeutic potential has not been fully exploited, and it could provide a new non-toxic approach to many diseases. This traditional medicinal food plant should receive more attention and in-depth research in the future.

RESUMO

OBJECTIVE: The study investigates the impact of preoperative rehabilitation on the surgical prognosis of frail older patients. METHOD: The effect sizes of all studies retrieved and included by the nine databases were analyzed and expressed as RR and WMD. RESULTS: 8 studies with 902 participants met the criteria for inclusion. A significant reduction in total complications (RR = 0.84, 95 % CI = 0.73 to 0.97, P = 0.021) and the 6MWT after surgery (WMD = 74.76, 95 % CI = 44.75 to 104.77, P = 0.000) was observed in the prehabilitation group. But it had no differences in mortality(RR = 1.89, 95 % CI = 0.75 to 4.72, P = 0.176), readmission rates(RR = 1.04, 95 % CI = 0.56 to 1.91, P = 0.906) and LOS(WMD = -0.24, 95 % CI = -1.00 to 0.52, P = 0.540). CONCLUSIONS: Prehabilitation had positive effect on postoperative complications and functional recovery in frail older patients.

RESUMO

Physical activity (PA) has the potential to bring about favourable changes in plasma lipid profile. However, the relationship between PA and remnant cholesterol (RC) remains unclear. We aimed to study the link between PA and RC using the database of the 2007-2020 National Health and Nutrition Examination Survey (NHANES). PA was categorized based on Physical Activity Guidelines for Americans. A multivariate linear regression model was used to determine the correlations between PA and RC. The study involved a total of 18,396 participants and revealed that individuals whose PA met the guidelines by engaging in moderate-intensity PA at least 150 min per week had lower body mass index and showed decreased levels of triglyceride, TC, and haemoglobin A1c compared to those who were physically inactive, exercising <150 min per week. Participants whose intensity of PA meets PA guidelines had a lower level of RC than those who did not met PA guidelines (ß = -1.3, 95% confidence interval [CI]: -1.9 to -0.7, p < 0.001), even after adjusting for confounders. During subgroup analysis, we observed that race (pinteraction = 0.0089) emerged as a significant factor of interaction.

RESUMO

Little is known about antibody responses to natural Omicron infection and the risk factors for poor responders in patients with hematological malignancies (HM). We conducted a multicenter, prospective cohort study during the latest Omicron wave in Chongqing, China, aiming to compare the antibody responses, as assessed by IgG levels of anti-receptor binding domain of spike protein (anti-S-RBD), to Omicron infection in the HM cohort (HMC) with healthy control cohort (HCC), and solid cancer cohort (SCC). In addition, we intend to explore the risk factors for poor responders in the HMC. Among the 466 HM patients in this cohort, the seroconversion rate was 92.7%, no statistically difference compared with HCC (98.2%, p = 0.0513) or SCC (100%, p = 0.1363). The median anti-S-RBD IgG titer was 29.9 ng/mL, significantly lower than that of HCC (46.9 ng/mL, p < 0.0001) or SCC (46.2 ng/mL, p < 0.0001). Risk factors associated with nonseroconversion included no COVID-19 vaccination history (odds ratio [OR] = 4.58, 95% confidence interval [CI]: 1.75-12.00, p = 0.002), clinical course of COVID-19 ≤ 7 days (OR = 2.86, 95% CI: 1.31-6.25, p = 0.008) and severe B-cell reduction (0-10/µL) (OR = 3.22, 95% CI: 1.32-7.88, p = 0.010). Risk factors associated with low anti-S-RBD IgG titer were clinical course of COVID-19 ≤ 7 days (OR = 2.58, 95% CI: 1.59-4.18, p < 0.001) and severe B-cell reduction (0-10/µL) (OR = 2.87, 95% CI: 1.57-5.24, p < 0.001). This study reveals a poor antibody responses to Omicron (BA.5.2.48) infection in HM patients and identified risk factors for poor responders. Highlights that HM patients, especially those with these risk factors, may be susceptible to SARS-CoV-2 reinfection, and the postinfection vaccination strategies for these patients should be tailored. Clinical trial: ChiCTR2300071830.

RESUMO

Hypertensive patients with snoring and elevated plasma homocysteine levels are common. When these factors are combined, the risk of coronary heart disease (CHD) is high. Herein, we developed and validated an easy-to-use nomogram to predict high-risk CHD in snoring hypertensive patients with elevated plasma homocysteine.Snoring patients (n = 1,962) with hyperhomocysteinemia and hypertension were divided into training (n = 1,373, 70%) and validation (n = 589, 30%) sets. We extracted CHD predictors using multivariate Cox regression analysis, then constructed a nomogram model. Internal validation using 1,000 bootstrap resampling was performed to assess the consistency and discrimination of the predictive model using the area under the receiver operating characteristic curve (AUC) and calibration plots.We constructed a nomogram model with the extracted predictors, including age, waist-height ratio, smoking, and low-density lipoprotein cholesterol levels. The AUCs of the training and validation cohorts at 80 months were 0.735 (95% CI: 0.678-0.792) and 0.646 (95% CI: 0.547-0.746), respectively. The consistency between the observed CHD survival and the probability of CHD survival in the training and validation sets was acceptable based on the calibration plots. A total of more than 151 points in the nomogram can be used in the identification of high-risk patients for CHD among snoring hypertensive patients with elevated plasma homocysteine.We developed a CHD risk prediction model for snoring hypertension patients with hyperhomocysteinemia. Our findings provide a useful clinical tool for the rapid identification of high-risk CHD at an early stage.

RESUMO

Biogenic sulfidation of zero-valent iron (ZVI) using sulfate reducing bacteria (SRB) has shown enhanced dechlorination rates comparable to those produced by chemical sulfidation. However, controlling and sustaining biogenic sulfidation to enhance in situ dechlorination are poorly understood. Detailed interactions between SRB and ZVI were examined for 4 months in column experiments under enhanced biogenic sulfidation conditions. SRB proliferation and changes in ZVI surface properties were characterized along the flow paths. The results show that ZVI can stimulate SRB activity by removing excessive free sulfide (S2-), in addition to lowering reduction potential. ZVI also hinders downgradient movement of SRB via electrostatic repulsion, restricting SRB presence near the upgradient interface. Dissolved organic carbon (e.g., >2.2 mM) was essential for intense biogenic sulfidation in ZVI columns. The presence of SRB in the upgradient zone appeared to promote the formation of iron polysulfides. Biogenic FeSx deposition increased the S content on ZVI surfaces ∼3-fold, corresponding to 3-fold and 2-fold improvements in the trichloroethylene degradation rate and electron efficiency in batch tests. Elucidation of SRB and ZVI interactions enhances sustained sulfidation in ZVI permeable reactive barrier.

RESUMO

This study aims to summarize the available data and determine if the presence of venous thromboembolism (VTE) immune-related adverse event (irAE) in patients with immune checkpoint inhibitor (ICI) therapy is associated with improved treatment efficacy and clinical outcomes, which in turn was used to help optimize patient selection for anticoagulation therapy and inform rational treatment strategies for overcoming the mechanisms of ICI resistance. PubMed, Embase, Web of Science, and Cochrane Library were searched up to March 18, 2023, for studies assessing the relationship between VTE irAE development during ICI therapy and cancer outcomes. Seven primary articles with a total of 4437 patients were included in the overall survival (OS) meta-analysis. Patients with VTE had a significant increase in overall mortality compared to patients without VTE in adjusted hazard ratios (HRs 1.36, 95% confidence interval [CI] 1.06-1.75, P = .02). In the studies where immortal time bias (ITB) was accounted for, patients with VTE irAE also had poor OS than those without. HR and the corresponding 95% CI values in the non-ITB group were 2.53 (1.75-3.66, P < .00001) with low heterogeneity (P = .17, I2 = 48%) and 1.21 (1.06-1.37, P = .004) in the ITB group with no heterogeneity (P = .95, I2 = 0%), respectively. Despite the heterogeneity identified, the evidence does suggest that VTE irAE occurrence could be served as a prognostic indicator, with higher frequencies of occurrence associated with poorer OS. However, the fundamental role of this association with clinical consequences should be further investigated in large cohorts and clinical trials.

RESUMO

Despite substantial advances in targeting mutant KRAS, tumor resistance to KRAS inhibitors (KRASi) remains a major barrier to progress. Here, we report proteostasis reprogramming as a key convergence point of multiple KRASi-resistance mechanisms. Inactivation of oncogenic KRAS down-regulated both the heat shock response and the inositol-requiring enzyme 1α (IRE1α) branch of the unfolded protein response, causing severe proteostasis disturbances. However, IRE1α was selectively reactivated in an ER stress-independent manner in acquired KRASi-resistant tumors, restoring proteostasis. Oncogenic KRAS promoted IRE1α protein stability through extracellular signal-regulated kinase (ERK)-dependent phosphorylation of IRE1α, leading to IRE1α disassociation from 3-hydroxy-3-methylglutaryl reductase degradation (HRD1) E3-ligase. In KRASi-resistant tumors, both reactivated ERK and hyperactivated AKT restored IRE1α phosphorylation and stability. Suppression of IRE1α overcame resistance to KRASi. This study reveals a druggable mechanism that leads to proteostasis reprogramming and facilitates KRASi resistance.

RESUMO

BACKGROUND: The utilization of acupuncture as a therapeutic intervention for the management of postoperative nausea and vomiting has experienced a notable increase in its popularity, and the purpose of this analysis is to provide a comprehensive understanding of the level of concern within the academic discipline and the main contributors and their partnership, as well as to identify research focal points and trends. METHODS: A comprehensive search was carried out to identify relevant articles on the topic of acupuncture therapy for PONV in the Web of Science and China National Knowledge Internet. The search spanned from January 1, 2011, to June 6, 2023. The annual publications were count to see the degree of scholarly attention devoted to the discipline and how it has changed over time. A statistical analysis of article distribution across various journals was conducted to serve a rough indicator for assessing the quality of articles. And a bibliometric analysis was conducted using the software CiteSpace to visually analyze various aspects of the literature. Analyze authors, institutions and countries to identify the main contributors and their collaborative relationship; and analyze keywords and references to explore research hotspots and trends. RESULTS: This study examined a comprehensive collection of 819 articles focused on acupuncture therapy for PONV, demonstrating a varying upward trend in the quantity of publications. Notably, the most productive author and institution were identified as Zheng Man and Guangzhou University of Traditional Chinese Medicine, respectively. While China had the highest number of publications, the United States held a greater prominence in this specific field. Collaboration among contributors was found to be weak. High-frequency keywords in the publications included "transcutaneous electrical acupoint stimulation," "electroacupuncture," "pain," and so forth. The literature with the highest citation count pertained to "Stimulation of the wrist acupuncture point PC6 for preventing postoperative nausea and vomiting," while the article with the highest centrality was "Consensus Guidelines for the Management of Postoperative Nausea and Vomiting." Several large clusters obtained from the references are also included "postoperative pain," "transcutaneous electrical acupoint stimulation". Nothing pertaining to mechanism study was found in the analysis results. CONCLUSION: The utilization of acupuncture for the treatment of postoperative nausea and vomiting has been gaining increasing recognition, although there remains room for improvement in the quality of research conducted in this area. Chinese authors and institutions have emerged as significant contributors to this field, while the United States has demonstrated greater proficiency in fostering collaborative efforts. It is imperative to enhance collaboration among these contributors. The current focal points of acupuncture for PONV encompass pain management, electroacupuncture, auricular acupuncture, and transcutaneous electrical acupoint stimulation. Additionally, TEA and enhanced recovery after surgery have been identified as the forefronts of research in this particular domain. In addition, there is still much room for research in the aspect of mechanism and insurance coverage. This study provides an in-depth perspective on acupuncture for PONV, which offers reference material for clinicians with rational choice of therapeutic scheme, educators with hot topics, and researchers with valuable research directions.

RESUMO

BACKGROUND: Cystatin C is a novel biomarker to identify renal dysfunction and cardiovascular risk. OBJECTIVE: The aim of this study was to investigate the role of cystatin C in non-invasive risk prediction in a large cohort of patients with pre-capillary pulmonary hypertension (PH). METHOD: We retrospectively analyzed pre-capillary PH patients with available cystatin C and hemodynamic data derived from right heart catheterization. RESULTS: A total of 398 consecutive patients with confirmed pre-capillary PH were recruited from Fuwai Hospital between November 2020 and November 2021. Over a median duration of 282 days, 72 (18.1%) of these patients experienced clinical worsening. Cystatin C levels significantly correlated with cardiac index (r = -0.286, P < 0.001), mixed venous oxygen saturation (r = -0.216, P < 0.001), and tricuspid annular plane systolic excursion (r = -0.236, P < 0.001), and high cystatin C levels independently predicted a poor prognosis after adjusting potential confounders in different models (all P < 0.05). A three-group non-invasive risk model was constructed based on the combined assessment of the cystatin C and WHO-FC using dichotomous cut-off value. Those patients with higher cystatin C (≥ 1.0 mg/L) and a worse WHO-FC experienced the highest risk of endpoint occurrence. The predictive capacity of this model was comparable to that of an existing invasive risk stratification model (area under curve: 0.657 vs 0.643, P = 0.619). CONCLUSIONS: Cystatin C levels were associated with disease severity and prognosis in patients with pre-capillary PH. A combination of high cystatin C and advanced WHO-FC identifies patients at particularly high risk of clinical deterioration.

RESUMO

LINC01354 is a long non-coding RNA (lncRNA) highly expressed in gastric cancer (GC). However, studies have shown that it plays a critical role in the progression of other tumors. This study attempts to uncover the role of LINC01354 in GC. LINC01354 expression in GC tissues and cell lines was assessed using qRT-PCR. Subsequently, LINC01354 knockdown and overexpression were induced in GC cells, and epithelial-mesenchymal transition (EMT) progression was detected. A dual-luciferase reporter assay was used to assess the relation between LINC01354, miR-153-5p, and CADM2. Finally, the metastatic ability of GC cells was assessed by Transwell and wound healing assays. LINC01354 expression was abnormally elevated in cancerous tissues and GC cells, and LINC01354 knockdown suppressed EMT progression, migration, and invasion of GC cells. Transfection of miR-153-5p mimics inhibited the expression of CADM2 by banding to the 3'UTR region, while LINC01354 promoted CADM2 expression by blocking miR-153-5p. The fluorescence experiment indicated that CADM2 is directly regulated by LINC01354/miR-153-5p. Overexpression of LINC01354 promoted EMT progression, migration, and invasion of GC cells, which could be absolutely reversed by co-expression of miR-153-5p. Our research demonstrates that LINC01354 has an important function in the EMT progression of GC cells. LINC01354 promotes GC cell migration and invasion by adjusting miR-153-5p/CADM2 expression.
