Construction of clinical research nurse training program based on position competence.

BACKGROUND: As one of the most important members in clinical trials, the number of clinical research nurses (CRN) can't keep up with the growth of experimental projects, so it is urgent to build clinical research training and strengthen the background knowledge of nurses. AIM: To construct CRN training program based on position competence, accelerate the construction of CRN talent pool, and provide scientific guidance significance for CRN training. METHODS: Based on the position competence model, combined with literature research and qualitative interview results, the first draft was prepared of the CRN training program. Two rounds of correspondence with 16 experts were conducted using the Delphi method to determine the training program. RESULTS: The effective recovery rate of the expert correspondence questionnaire was 100% and the authority coefficients of the 2 rounds of experts were 0.826 and 0.895. Finally, 4 first-level indicators and determine 15 s-level indicators of training objectives. The training program included 4 first-level indicators, training requirements, content, methods, assessment and evaluation, 15 s-level indicators, and 74 third-level indicators. CONCLUSION: The CRN training program based on position competence is scientific and extendable, providing a basis for participation in CRN training.

Resveratrol reduces lactate production and modifies the ovarian cancer immune microenvironment.

Tumor cells show deregulated metabolism leading to an enrichment of lactate in the tumor microenvironment (TME). This lactate-rich environment has been reported to impair effector T cells. However, T-regulatory cells (Tregs) show metabolic advantages in lactate-rich TME that maintain a strong suppression of effector T cells, which leads to tumor immune evasion. Therefore, the glycolytic process of tumors could represent a therapeutic target, and agents that modify the energy metabolism of tumor cells have therapeutic potential. Resveratrol is a naturally occurring polyphenol that has been confirmed to suppress tumor cells' glycolytic metabolism. In this study, we show that resveratrol induces metabolic reprogramming in ovarian cancer cells. Resveratrol increases oxidative and decreases glycolysis, in association with decreased lactate production both in vitro and in vivo. Lactate reduction in TME weakens the suppressive function of Tregs, and subsequently restores anti-tumor immunity. Significantly, combined resveratrol and PD-1 blockade promote anti-tumor efficacy. These data suggest that resveratrol's anti-tumor actions in ovarian cancer could be explained, in part, through modification of the anti-tumor immunity, and indicate a novel treatment strategy for improving immune checkpoint blockade therapy using resveratrol.

The Landscape of Exosome-Derived Non-Coding RNA in Leukemia.

Leukemia is a group of life-threatening hematological malignancies which is currently incurable and often accompanied by drug resistance or disease relapse. Understanding the pathogenesis of leukemia and finding specific therapeutic targets and biomarkers is of great importance to improve the clinical efficacy of leukemia. Exosome-derived ncRNAs have been demonstrated as critical components of intercellular communication and function as key facilitators in the leukemia biological process. This review outlines the current investigations of exosomal ncRNAs (including miRNA, circRNA, and lncRNA) as important mediators of leukemia and potential therapeutic targets and biomarkers for leukemia treatment. Moreover, we generally analyze the prospects and challenges for exosomal ncRNAs from the aspects of research and clinical application.

Midterm Prognosis of Sexagenary Patients after Transcatheter Device Closure of Atrial Septal Defects: a Single-Chinese Center Experience

Abstract Introduction: The objective of this study is to evaluate the efficacy and midterm prognosis of transcatheter device closure of atrial septal defects (ASDs) in sexagenary patients in China. Methods: Forty-six sexagenary patients who underwent transcatheter device closure of ASDs in our hospital were included in this study. The patients' preoperative and postoperative clinical symptoms, echocardiographic results, and quality of life were investigated and analyzed. Results: Of the 46 sexagenary patients who participated in the study, 40 completed the study. After ASD closure, the clinical symptoms of the patients significantly improved, and the number of patients with dyspnea and palpitations significantly decreased after the operation. According to the echocardiographic results, few patients had a tiny residual shunt after closure, but the shunt disappeared completely at the three-month follow-up. The size of the right ventricular cavity was significantly smaller postoperatively compared with preoperatively. Regarding the patients' quality of life, their feedback in all dimensions of the 36-Item Short-Form Health Survey (or SF-36) was significantly improved at the three-month follow-up, and it remained improved at the one-year follow-up. Conclusion: The clinical outcomes and subjective quality of life of sexagenary patients with ASDs improved significantly after transcatheter device closure of ASDs. Therefore, we believe that for sexagenary patients with ASDs, transcatheter device closure is a favorable treatment.

Impact of High-Frequency Oscillatory Ventilation Combined With Volume Guarantee on Lung Inflammatory Response in Infants With Acute Respiratory Distress Syndrome After Congenital Heart Surgery: A Randomized Controlled Trial.

OBJECTIVES: Congenital heart disease (CHD) after cardiopulmonary bypass can cause systemic inflammation, and its degree is closely related to the incidence of acute respiratory distress syndrome (ARDS). The purpose of this study was to determine the effectiveness of high-frequency oscillatory ventilation (HFOV) combined with volume guarantee (VG) in reducing systemic inflammation in infants with ARDS after cardiopulmonary bypass for congenital heart surgery. DESIGN: A randomized controlled trial. SETTING: Single-center study in a tertiary teaching hospital. PARTICIPANTS: A total of 58 infants with ARDS after congenital heart surgery were eligible and were randomized to the HFOV (n = 29) or the HFOV-VG (n = 29) between January 2020 and January 2021. INTERVENTIONS: Tracheal aspirate samples for the measurement of interleukin (IL)-6, IL-8, and tumor necrosis factor-α (TNF-α) were obtained on days one, two, and three of HFOV or HFOV-VG ventilation. MEASUREMENTS AND MAIN RESULTS: The authors found a significantly increasing trend in the HFOV group mean values of IL-6, IL-8, and TNF-α (p < 0.05 on days two and three v day one), and IL-6, IL-8, and TNF-α levels were significantly higher on day three in the HFOV group versus the HFOV+VG group (p < 0.05). In addition, the incidences of hypocapnia and hypercapnia in infants supported with HFOV-VG were significantly lower (p < 0.05). Furthermore, the postoperative mechanical ventilation duration in the HFOV-VG group also was shorter than that in the HFOV group (p < 0.05). CONCLUSION: Compared with HFOV alone, HFOV-VG reduced proinflammatory systemic reactions after congenital cardiac surgery, decreased the incidences of hypercapnia and hypocapnia, and shortened the postoperative mechanical ventilation duration.

Effect of postoperative administration of inhaled nitric oxide combined with high-frequency oscillatory ventilation in infants with acute hypoxemic respiratory failure and pulmonary hypertension after congenital heart surgery: A retrospective cohort study.

OBJECTIVE: To evaluate the effect of inhaled nitric oxide (iNO) combined with high-frequency oscillatory ventilation (HFOV) in the treatment of infants with acute hypoxemic respiratory failure (AHRF) and pulmonary hypertension (PH) after congenital heart surgery. METHODS: A retrospective study was conducted on 63 infants with AHRF and PH after congenital heart surgery in our cardiac intensive care unit (CICU) from January 2020 to March 2021. A total of 24 infants in the A group were treated with HFOV combined with iNO, and 39 infants in the B group were treated with HFOV. Relevant clinical data were collected. RESULTS: Comparing the two groups, the improvement of the oxygenation index, PaO2 and PaO2 /FiO2 was more obvious for patients in the A group than for those in the B group after intervention (p < .05). Reexamination on the third day after the initiation of HFOV treatment indicated that the systolic pulmonary artery pressure in the A group was significantly lower than that in the B group (p < .05). In addition, the duration of mechanical ventilation and the length of CICU stay in the A group were shorter than those in the B group (p < .05). However, complications between the two groups were not statistically significant. No important adverse effects arose. CONCLUSIONS: For infants with AHRF and PH after congenital heart surgery, iNO combined with HFOV is superior to HFOV alone to improve oxygenation, decrease pulmonary pressure, and shorten the duration of mechanical ventilation and the length of CICU stay, with no adverse effects.

Midazolam for conscious sedation in transcatheter device closure of atrial septal defects guided solely by transthoracic echocardiography.

OBJECTIVES: To investigate the safety and feasibility of midazolam for conscious sedation in transcatheter device closure of atrial septal defects guided solely by transthoracic echocardiography. METHODS: A retrospective analysis was performed on 55 patients who underwent transcatheter device closure of atrial septal defects from October, 2019 to May, 2020. All patients received intravenous midazolam and local anesthesia with lidocaine to maintain sedation. A group of previous patients with unpublished data who underwent the same procedure with general anesthesia was set as the control group. The relevant clinical parameters, the Ramsay sedation scores, the numerical rating scale, and the post-operative satisfaction questionnaire were recorded and analyzed. RESULTS: In the midazolam group, the success rate of atrial septal defect closure was 98.2%. Hemodynamic stability was observed during the procedure. None of the patients needed additional endotracheal intubation for general anesthesia. Compared with the control group, the midazolam group had no statistically significant differences in the Ramsay sedation score and numerical rating scale scores. Patients in the midazolam group experienced more post-operative satisfaction than those in the control group. CONCLUSIONS: Conscious sedation using midazolam is a safe and effective anesthetic technique for transcatheter device closure of atrial septal defects guided solely by transthoracic echocardiography.

Therefore, we believe that for sexagenary patients with ASDs, transcatheter device closure is a favorable treatment.

WeChat-assisted health education and preoperative care improve the mental state of parents of children with ventricular septal defect.

Many studies have shown that parents of children with congenital heart disease have more stress, anxiety and depression. This study was aimed to explore the effect of implementing WeChat-assisted health education and preoperative care on parents of children with the restrictive ventricular septal defect to improve the psychological state. A prospective randomized controlled study was conducted in a provincial hospital in China. Participants were randomly divided into an intervention group and a control group to explore the psychological state of parents of children with the restricted ventricular septal defect. Before surgery, the state-trait anxiety inventory scale score (STAI) of the WeChat group were 26.8 ± 8.2 and 27.3 ± 7.0, which were significantly higher than those of the leaflet group (37.6 ± 12.9 and 39.3 ± 11.7). Compared with the STAI score at the first visit, the WeChat group preoperative score was significantly lower (P < 0.05). The rate of loss to follow-up in the WeChat group (0%) was significantly lower than that of the leaflet group (14.3%). The complication of the leaflet group was significantly higher than that of the WeChat group. Health education and preoperative care for parents of children with restrictive ventricular septal defect through WeChat can effectively improve the parents' mental state and reduce the incidence of complications and the rate of loss to follow-up.

Comparison of Two Noninvasive Ventilation Strategies (NHFOV Versus NIPPV) as Initial Postextubation Respiratory Support in High-Risk Infants After Congenital Heart Surgery.

OBJECTIVE: This study aimed to compare the effects of nasal high-frequency oscillatory ventilation (NHFOV) and noninvasive positive-pressure ventilation (NIPPV) as the initial postextubation therapies on preventing extubation failure (EF) in high-risk infants younger than three months after congenital heart surgery (CHS). DESIGN: This was a single-center, randomized, unblinded clinical trial. SETTING: The study was performed in a teaching hospital. PARTICIPANTS: Between January 2020 and January 2021, a total of 150 infants underwent CHS in the authors' hospital. INTERVENTIONS: Infants younger than three months with a high risk for extubation failure who were ready for extubation were randomized to either an NHFOV therapy group or an NIPPV therapy group, and received the corresponding noninvasive mechanical ventilation to prevent EF. MEASUREMENTS: Primary outcomes were reintubation, long-term noninvasive ventilation (NIV) support (more than 72 hours), and the time in NIV therapy. The secondary outcomes were adverse events, including mild-moderate hypercapnia, severe hypercapnia, severe hypoxemia, treatment intolerance, signs of discomfort, unbearable dyspnea, inability to clear secretions, emesis, and aspiration. MAIN RESULTS: Of 92 infants, 45 received NHFOV therapy, and 47 received NIPPV therapy after extubation. There were no significant differences between the NHFOV and the NIPPV therapy groups in the incidences of reintubation, long-term NIV support, and total time under NIV therapy. No significant difference was found of the severe hypercapnia between the two groups, but NHFOV treatment significantly decreased the rate of mild-moderate hypercapnia (p < 0.05). Other outcomes were similar in the two groups. CONCLUSIONS: Among infants younger than three months after CHS who had undergone extubation, NIPPV therapy and NHFOV therapy were the equivalent NIV strategies for preventing extubation failure, and NHFOV therapy was more effective in avoiding mild-moderate hypercapnia.

WeChat-Assisted Preoperative Health Education Reduces Burden of Care on Parents of Children with Simple Congenital Heart Disease: a Prospective Randomized Controlled Study

Abstract Objective: The purpose of this study was to explore the clinical effect of preoperative health education based on the WeChat platform for parents of children with simple congenital heart disease. Methods: In this study, participants were randomly divided into an intervention group (WeChat group, n=40) and a control group (leaflet group, n=40) in our center. All parents were required to complete the Family Caregiver Task Inventory (FCTI) on the first visit and the Zarit Burden Interview (ZBI) and FCTI before the operation. Clinical, family and relevant data from children and parents were collected and subsequently analyzed. Results: Before the operation, the FCTI score and the ZBI score in the WeChat group were significantly lower than those in the control group (P=0.010, P=0.027, respectively). Compared to the FCTI score on the first visit, the preoperative status score was significantly lower in the WeChat group (P=0.008). The rate of loss to follow-up and complications in the WeChat group was also significantly lower than in the control group (P=0.003). Conclusion: Preoperative health education assisted by the WeChat platform for parents of children with simple congenital heart disease can effectively improve the parents' care ability and reduce the burden of care, preoperative complications and the rate of loss to follow-up.

Effect of High-Frequency Oscillatory Ventilation Combined With Pulmonary Surfactant in the Treatment of Acute Respiratory Distress Syndrome After Cardiac Surgery: A Prospective Randomised Controlled Trial.

Background: This study aimed to evaluate the effects of pulmonary surfactant (PS) combined with high-frequency oscillatory ventilation (HFOV) or conventional mechanical ventilation (CMV) in infants with acute respiratory distress syndrome (ARDS) after congenital cardiac surgery. Methods: A total of 61 infants with ARDS were eligible and were randomised to the CMV + PS group (n = 30) or the HFOV + PS group (n = 31) between January 2020 and December 2020. The primary outcomes were the changes in arterial blood gas parameters. The duration of mechanical ventilation, length of hospitalisation and the incidence of complications were considered secondary outcomes. Results: A total of 61 infants completed the study. In the HFOV + PS group, the blood gas analysis results were significantly improved (P < 0.05), while the duration of mechanical ventilation and length of hospitalisation were shorter than the CMV + PS group (P < 0.05). However, the incidence of complications was not different between the two groups (P > 0.05). Conclusions: Compared with the CMV + PS group, the HFOV + PS group showed significantly improved ABG variables and had a shortened length of hospitalisation and mechanical ventilation in infants with ARDS after cardiac surgery. Clinical Trial Registration: Chinese Clinical Trial Registry; Number: ChiCTR2000039457.

Application of Remote Follow-Up Via the WeChat Platform for Patients who Underwent Congenital Cardiac Surgery During the COVID-19 Epidemic

Abstract Objective: To investigate the effect of WeChat-based telehealth services on the postoperative follow-up of children who underwent congenital heart surgery during the COVID-19 epidemic. Methods: This study retrospectively analyzed the clinical and family data of 108 children who underwent congenital heart surgery and underwent remote follow-up via the WeChat platform from December 2019 to March 2020 in our hospital. Results: During the follow-up period, the WeChat platform was used to refer 8 children with respiratory infection symptoms to local hospitals for treatment. Two children with poor incision healing were healed after we used the WeChat platform to guide the parents in dressing the wounds on a regular basis at home. Nutritional guidance was given via the WeChat platform to 13 patients with poor growth and development. The psychological evaluation results of the parents showed that the median (range) SDS score was 43 (34-59), and 7 parents (6.5%) were classified as depressed; the median (range) SAS score was 41 (32-58), and 12 parents (11.1%) were classified as having mild anxiety. Conclusion: The use of WeChat-based telehealth services was effective for the remote postoperative follow-up of children who underwent congenital cardiac surgery during the COVID-19 epidemic. Providing WeChat-based telehealth services can reduce the amount of travel required for these children and their families, which is helpful for controlling and preventing the spread of COVID-19.

Application of high-frequency oscillation ventilation combined with volume guarantee in infants with acute hypoxic respiratory failure after congenital heart surgery.

OBJECTIVE: This study aimed to evaluate the efficacy and safety of high-frequency oscillation ventilation combined with volume guarantee (HFOV-VG) compared with the safety and efficacy of HFOV alone in infants with acute hypoxemic respiratory failure (AHRF) after congenital heart surgery. METHODS: We retrospectively analyzed the clinical data of 44 infants who were ventilated for AHRF after congenital heart surgery between January 2020 and January 2021. HFOV alone was used in 23 of the 44 infants, whereas HFOV-VG was used in the other 21 infants. RESULTS: The average frequency tidal volume (VThf) of the HFOV-VG group was lower than that of the HFOV group, and the proportion of VThf exceeding the target range of infants in the HFOV-VG group was also lower (p < .01). In addition, the incidence of hypocapnia and hypercapnia in infants supported with HFOV-VG was significantly lower (p < .01). Furthermore, the duration of invasive ventilation and the median ventilator adjustment per hour in the HFOV-VG group was also lower than that in the HFOV group (p < .01). CONCLUSIONS: Compared with HFOV alone, HFOV-VG decreases the fluctuation of VThf and the incidence of hypercapnia and hypocapnia. Moreover, it reduces the workload of bedside medical staff. Further studies are needed to confirm the efficacy and safety of HFOV-VG as a routine respiratory support strategy for congenital heart disease during the perioperative period.

Effects of different oral care strategies on postoperative pneumonia in infants with mechanical ventilation after cardiac surgery: a prospective randomized controlled study.

BACKGROUND: To explore the effects of different oral care strategies on postoperative pneumonia in infants with mechanical ventilation after cardiac surgery. METHODS: A prospective randomized controlled study was conducted at a hospital in Fujian Province, China. Participants were randomly divided into the breast milk oral care group, physiological saline oral care group, and sodium bicarbonate oral care group to explore the effects of different oral care strategies on postoperative pneumonia in infants on mechanical ventilation cardiac surgery. RESULTS: The mechanical ventilation duration, the hospitalization costs, and the length of intensive care unit (ICU) stay and postoperative hospital stay in the breast milk oral care group were significantly shorter than those in the physiological saline oral care group and the sodium bicarbonate oral care group. The incidence of postoperative pneumonia in the breast milk oral care group was 3.2%, which was significantly lower than that in the physiological saline oral care group (22.6%) and the sodium bicarbonate oral care group (19.4%). CONCLUSIONS: Using breast milk for oral care in infants after cardiac surgery has a lower incidence of postoperative pneumonia than traditional oral care strategies of physiological saline and sodium bicarbonate, and it is worthy of clinical application.

Impact of Music Therapy on Preoperative Anxiety and Degree of Cooperation With Anesthesia Induction in Children With Simple Congenital Heart Disease.

PURPOSE: To evaluate the impact of music therapy (MT) on preoperative anxiety and degree of cooperation with anesthesia induction in children with simple congenital heart disease (CHD). DESIGN: A randomized controlled clinical study. METHODS: Ninety children were randomly assigned to the MT and control groups. The MT groups underwent a preoperative 30-minute session of MT, whereas the control group did not listen to any music and had the same amount of quiet time. The modified Yale Preoperative Anxiety Scale-Short Form (mYPAS-SF) was used to evaluate the patients' preoperative anxiety on entering the anesthesia waiting area (T1), 10 minutes after entering the waiting area (T2), and during the initiation of anesthesia induction (T3); the degree of cooperation with anesthesia induction was assessed using the Induction Compliance Checklist. The mean arterial blood pressure (MAP) and heart rate (HR) at T1, T2, T3, and T4 (the time of successful anesthesia) were also recorded. FINDINGS: One child was excluded from the MT group, and one was excluded from the control group. No difference was found in the mYPAS-SF score, MAP, or HR between the two groups at T1. The mYPAS-SF scores of the MT group were significantly lower than those of the control group at T2 and T3. At T2, T3, and T4, the MAP and HR of the MT group were lower than those of the control group. A statistically significant difference was found in the Induction Compliance Checklist score between the two groups. CONCLUSIONS: MT can reduce preoperative anxiety and improve the degree of cooperation with anesthesia induction.

WeChat-assisted pre-operative health education improves the quality of life of parents of children with ventricular septal defects: A prospective randomised controlled study.

AIM: This study aimed to explore the effect of implementing pre-operative WeChat-assisted health education for parents of children with restrictive ventricular septal defects to improve their quality of life. METHODS: A prospective randomised controlled study was conducted in a provincial hospital in China. Participants were randomly divided into the intervention group (WeChat group, n = 35) and the control group (leaflet group, n = 35). The quality of life of parents of children with restricted ventricular septal defects was studied. RESULTS: Compared with the leaflet group, the WeChat group had a significantly lower score for the pre-operative Self-Rating Anxiety Scale (SAS) (P < 0.05). The pre-operative SAS score in the WeChat group was significantly lower than that at the first visit (P < 0.05). However, the SAS score in the leaflet group was similar at the time of preoperation and the first visit (P > 0.05). The pre-operative scores of the World Health Organization Quality of Life-BREF (WHOQOL-BREF) scale in the physiological, psychological, social, and environmental fields and the total life quality score in the WeChat group were significantly higher than those of the leaflet group (P < 0.05). CONCLUSION: Implementing pre-operative WeChat-assisted health education for parents of children with restrictive ventricular septal defects can effectively relieve their anxiety and improve their quality of life.

Evaluation of analgesic and sedative effects of remifentanil-based fast-track anesthesia in children undergoing transthoracic device closure of ventricular septal defects.

BACKGROUND: This study aimed to evaluate the analgesic and sedative effects of remifentanil-based fast-track cardiac anesthesia in children undergoing transthoracic device closure of ventricular septal defects (VSDs). METHODS: A retrospective analysis was conducted on 62 children who underwent transthoracic device closure of VSDs from May 2019 to August 2019. The patients were divided into two groups based on the anesthesia methods: group F was given remifentanil-based fast-track cardiac anesthesia, and Group C was given conventional anesthesia. Patient-related clinical data, postoperative analgesia scores, and sedation scores were collected and analyzed. RESULTS: There was no significant difference in intraoperative hemodynamic changes, bispectral index values, postoperative analgesia scores, sedation scores, or the incidence of adverse events between the two groups. Compared with Group C, the duration of mechanical ventilation and the length of intensive care unit (ICU) and hospital stay in group F were significantly lower. CONCLUSION: Remifentanil-based fast-track anesthesia can be safely applied in children undergoing transthoracic device closure of VSDs, with acceptable postoperative analgesia and sedation effects and shorter mechanical ventilation times and ICU and hospital stays compared with conventional anesthesia.

Health-Related Quality of Life in Children and Adolescents with Simple Congenital Heart Defects before and after Transcatheter Intervention Therapy: A Single-Center Study.

OBJECTIVE: To explore the health-related quality of life (HRQoL) of children and adolescents with simple congenital heart defects before and after the transcatheter intervention. METHODS: The Pediatric Quality of Life Inventory 4.0 scale was used to assess the quality of life of 78 children and adolescents before and after the transcatheter intervention and to evaluate the parents' perception of their children's quality of life. RESULTS: In all, 76 patients were completed the study. The results showed that the scores of the four dimensions and the total score for the quality of life of the patients significantly improved 1 month after the intervention. At 6 months after treatment, the scores in all dimensions continued to improve. From the parents' perspective, the scores of the patients in all dimensions improved significantly at 1 month and 6 months after treatment. In terms of the quality of life assessment, the self-assessment results of the patients were more positive than those of their parents. CONCLUSIONS: The results showed that the quality of life of children and adolescents with simple congenital heart defects can be positively affected by the transcatheter intervention. Moreover, this improvement is not transient and seems to increase over time.
