RESUMO

BACKGROUND: Catheter-related thrombosis is a common complication of the peripherally inserted central catheter (PICC) in neonates, leading to unintended tube removal and significantly affecting neonatal health and safety. Despite widespread reporting on the estimated occurrence and factors contributing to neonatal PICC-related thrombosis, these findings have not been synthesized. OBJECTIVES: The purpose of this study was to determine the incidence and risk factors of neonatal PICC-related thrombosis. DESIGN: Systematic literature review and meta-analysis. METHODS: Two independent researchers systematically explored multiple databases-such as PubMed, Medline, Embase and the Cochrane Library-from their inception until October 2023. Our study aggregates and scrutinizes studies specifically addressing the incidence and risk factors of neonatal PICC-related thrombosis. Employing the RevMan 5.3 software, a meta-analysis was executed to determine the incidence of both thrombosis and odds ratios (OR), accompanied by their respective 95% confidence intervals (CI) for the risk factors. RESULTS: A total of 327 articles were screened, and data from 24 studies were used in synthesis. Neonatal PICC-related thrombosis incidence varied from 0.23% to 17.91%. The pooled incidence was 2% (95% CI: 1%-2%; I2 = 94%; p < .0001). The study identified 12 risk factors, including insertion sites in the lower extremities (OR = 0.22; 95% CI: 0.09-0.56; p = .001), gestational age <28 weeks, abdominal pathology, fresh frozen plasma by day 5 > 50 mL/kg, PICC tip location (proximal placement), two lumens, three lumens, prolonged hospital stay, infection, mothers' use of anticoagulants, patients with cardiac insufficiency and being twin-to-twin transfusion syndrome donor. CONCLUSIONS: The analysis indicates an overall pooled incidence of neonatal PICC-related thrombosis of 2%. Twelve factors were identified as risks associated with neonatal PICC-related thrombosis. Understanding the risk factors can provide evidence-based recommendations for improving awareness, control and treatment and better nursing management. RELEVANCE TO CLINICAL PRACTICE: This systematic review and meta-analysis illuminates the incidence and risk factors linked to neonatal PICC-related thrombosis, delivering essential insights pivotal for clinical decision-making and enhancing patient care within neonatal health care settings.

RESUMO

Phasic cardiac vagal activity (CVA), reflecting ongoing, moment-to-moment psychophysiological adaptations to environmental changes, can serve as a predictor of individual difference in executive function, particularly executive performance. However, the relationship between phasic CVA and executive function demands requires further validation because of previous inconsistent findings. Moreover, it remains unclear what types of phasic changes of CVA may be adaptive in response to heightened executive demands. This study used the standard N-back task to induce different levels of working memory (WM) load and combined functional Near-Infrared Spectroscopy (fNIRS) with a multipurpose polygraph to investigate the variations of CVA and its interactions with cognitive and prefrontal responses as executive demands increased in fifty-two healthy young subjects. Our results showed phasic decreases in CVA as WM load increased (t (51) = -3.758, p < 0.001, Cohen's d = 0.526). Furthermore, phasic changes of CVA elicited by increased executive demands moderated the association of cognitive and cerebral hemodynamic variations in the prefrontal cortex (B = 0.038, SE = 0.014, p < 0.05). Specifically, as executive demands increased, individuals with larger phasic CVA withdrawal showed a positive relationship between cognitive and hemodynamic variations in the prefrontal cortex (ß = 0.281, p = 0.031). No such significant relationship was observed in individuals with smaller phasic CVA withdrawal. The current findings demonstrate a decrease in CVA with increasing executive demands and provide empirical support for the notion that a larger phasic CVA withdrawal can be considered adaptive in situations requiring high executive function demands.

RESUMO

Graphene family nanomaterials (GFNs) have attracted considerable attention in diverse fields from engineering and electronics to biomedical applications because of their distinctive physicochemical properties such as large specific surface area, high mechanical strength, and favorable hydrophilic nature. Moreover, GFNs have demonstrated the ability to create an anti-inflammatory environment and exhibit antibacterial effects. Consequently, these materials hold immense potential in facilitating cell adhesion, proliferation, and differentiation, further promoting the repair and regeneration of various tissues, including bone, nerve, oral, myocardial, and vascular tissues. Note that challenges still persist in current applications, including concerns regarding biosecurity risks, inadequate adhesion performance, and unsuitable degradability as matrix materials. This review provides a comprehensive overview of current advancements in the utilization of GFNs in regenerative medicine, as well as their molecular mechanism and signaling targets in facilitating tissue repair and regeneration. Future research prospects for GFNs, such as potential in promoting ocular tissue regeneration, are also discussed in details. We hope to offer a valuable reference for the clinical application of GFNs in the treatment of bone defects, nerve damage, periodontitis, and atherosclerosis.

RESUMO

BACKGROUND: The shortage of nurses has been a global human resources problem. A good professional growth environment is essential to developing potential nursing students and attracting nurses to join, and it has great significance in reducing nurse turnover. However, nurses' comprehensive perceptions of professional growth have not yet been examined. METHODS: A cluster sampling method was used to conduct a professional growth questionnaire survey on young nursing talents from a large Chinese public tertiary A hospital in March 2022. RESULTS: The score of professional growth among 243 young nursing talents was 57.92 ± 9.607, with a scoring rate of 77.23%. The scores for dimensions of professional growth, from lowest to highest, were rehabilitation growth, promotion speed, professional goal progress, and professional ability development. Attitudes towards participating in training, service as the quality manager or clinical teacher, self-efficacy, professional title, work-family support, education, and organizational commitment of young nursing talents were significantly associated with professional growth. CONCLUSION: The professional growth of young nursing talents was at a moderate level and needed to be strengthened. Nursing leaders and managers are expected to develop management practices to enhance young nursing talents' professional growth in combination with the related factors.

RESUMO

The purpose of this study was to evaluate the effect of the Task-Grabbing System on operating room efficiency. Based on the competition-driven concept of the 'Uber' app, an Task-Grabbing System was designed for task allocation and quality assessment. We implemented the Task-Grabbing System in our hospital operating room and compared the differences in consecutive operation preparation time, turnover time, and task completion time performed by surgical technicians for tasks such as patient pick-up, operating room cleaning, medical equipment recovery, three-piece set delivery, as well as blood gas analysis and intraoperative specimen submission before (October 2019) and after (December 2019) the implementation of the Task-Grabbing System. After the implementation of the Task-Grabbing System, the consecutive operation preparation time was reduced from the average of 43.56-38.55 min (P < 0.05), and the turnover time was decreased from the average of 14.25-12.61 min (P < 0.05). And the respective time consuming of surgical technicians for patients picking up, operating room cleaning, medical facilities recovering, the three-piece set delivering, blood gas analysis sending and intraoperative specimen submitting was significantly shortened (P < 0.05). The Task-Grabbing System could improve the operating room efficiency and effectively mobilize the enthusiasm and initiative of the surgical technicians.

RESUMO

A copper-catalyzed [4+2] cyclization reaction of isoquinolines and alkynes is developed for the one-step construction of isoquinolinone derivatives with multisubstituted bridging rings. The unique feature of this three-component tandem cyclization reaction is the functionalization of the C1, N2, C3, and C4 positions of 3-haloisoquinolines via the construction of new C-N, C═O, and C-C bonds. This dearomatization strategy for the synthesis of structurally complex isoquinolinone-bridged cyclic compounds offers good chemoselectivity, broad functional group compatibility, greenness, and high step economy.

RESUMO

Psychosocial stress is increasing, causing a growing number of people to suffer from hair loss. Stress-related corticotropin-releasing hormone (CRH) is associated with hair loss, but the mechanism by which hair follicles respond to stress and CRH remain poorly understood. The aim of the study is to elucidate the association between CRH and stress-related hair regenerative disorders, and reveal the potential pathological mechanisms. A chronic unpredictable stress mouse model and a chronic social defeat stress mouse model were used to examine the role of CRH and stress-related hair regrowth. Chronic unpredictable stress and chronic social defeat stress increased the expression of CRH and CRH receptors (CRHRs), and contributed to the onset of hair-cycle abnormalities. Psychoemotional stress and stress-related CRH blocked hair follicle regrowth, which could be restored by astressin, a CRHR antagonist. Long-term exposure to either chronic unpredictable stress or CRH induced a decrease in autophagy, which could be partially rescued by astressin. Activating CRHR, by stress or CRH administration, decreased autophagy via the mTOR-ULK1 signaling pathway to mediate hair regenerative disorders, which could be partially reversed through enhancing autophagy by administration of brefeldin A. These findings indicate that CRH-mediated autophagy inhibition play an important role in stress-induced hair regenerative disorders. CRH regulates the local hypothalamic-pituitary-adrenal axis of hair follicles, but also plays an independent pathogenic role in stress-related hair regenerative disorders through CRH-mediated autophagy inhibition. This work contributes to the present understanding of hair loss and suggests that enhancing autophagy may have a therapeutic effect on stress-induced hair loss.

RESUMO

BACKGROUND: Peripherally inserted central catheters (PICCs) are commonly used in neonatal intensive care units for extended intravenous nutrition and therapy. The selection of PICCs insertion sites can significantly influence insertion outcomes and neonatal safety. AIM: This study aimed to determine the most suitable insertion site in the lower extremities for neonatal PICCs. STUDY DESIGN: A retrospective case note review was conducted on PICCs inserted through lower extremity (LE) sites in a 40-bed tertiary-level neonatal intensive care unit at a university teaching hospital. The dates when data were accessed for research purposes were from June 2019 to June 2022. In total, 223 neonates were identified as having had PICCs, with 254 catheters inserted in the lower extremities. The STROBE checklist guided the reporting of this study. RESULTS: Neonates underwent PICC insertion via the LE vein, with an overall complication rate of 13.4% and a one-attempt success rate of puncture of 86.2%. The rates of complications, catheter occlusion, and catheter-related infection in the PICC group with insertion through the great saphenous vein were significantly lower than those in the femoral vein group (p < .05). The success rate was significantly higher than that in the femoral vein group (p < .05). Additionally, the incidence of total complications and catheter occlusion complications with PICC insertion via the right LE was significantly lower than that with insertion via the left LE (p < .05). CONCLUSION: Our study suggested that, when feasible, the saphenous vein in the right LE could be the most suitable insertion site for neonatal PICCs. RELEVANCE TO CLINICAL PRACTICE: These findings provide insights into the complications, indwelling time, and safety of neonatal PICCs in different LE sites, serving as a valuable reference for clinical practice. This study was retrospective in nature, and all staff involved obtained approved access to patient clinical data. Ethical approval was granted by the Ethics Committee of Xiangya Hospital, Central South University (registry number 2022010001).

RESUMO

BACKGROUND: While laparoscopic assistance is often entrusted to less experienced individuals, such as residents, medical students, and operating room nurses, it is important to note that they typically receive little to no formal laparoscopic training. This deficiency can lead to poor visibility during minimally invasive surgery, thus increasing the risk of errors. Moreover, operating room nurses and medical students are currently not included as key users in structured laparoscopic training programs. OBJECTIVES: The aim of this study is to evaluate the laparoscopic skills of OR nurses, clinical medical postgraduate students, and residents before and after undergoing virtual reality training. Additionally, it aimed to compare the differences in the laparoscopic skills among different groups (OR nurses/Students/Residents) both before and after virtual reality training. METHODS: Operating room nurses, clinical medical postgraduate students and residents from a tertiary Grade A hospital in China in March 2022 were selected as participants. All participants were required to complete a laparoscopic simulation training course in 6 consecutive weeks. One task from each of the four training modules was selected as an evaluation indicator. A before-and-after self-control study was used to compare the basic laparoscopic skills of participants, and laparoscopic skill competency was compared between the groups of operating room nurses, clinical medical postgraduate students, and residents. RESULTS: Twenty-seven operating room nurses, 31 clinical medical postgraduate students, and 16 residents were included. The training course scores for the navigation training module, task training module, coordination training module, and surgical skills training module between different groups (operating room nurses/clinical medical postgraduate/residents) before laparoscopic simulation training was statistically significant (p < 0.05). After laparoscopic simulation training, there was no statistically significant difference in the training course scores between the different groups. The surgical level scores before and after the training course were compared between the operating room nurses, clinical medical postgraduate students, and residents and showed significant increases (p < 0.05). CONCLUSION: Our findings show a significant improvement in laparoscopic skills following virtual surgery simulation training across all participant groups. The integration of virtual surgery simulation technology in surgical training holds promise for bridging the gap in laparoscopic skill development among health care professionals.

RESUMO

Increasing concerns about hair loss affect people's quality of life. Recent studies have found that sympathetic nerves play a positive role in regulating hair follicle stem cell activity to promote hair growth. However, no study has investigated sympathetic innervation of transplanted follicles. Rat vibrissa follicles were extracted and implanted under the dorsal skin of BALB/c-nu/nu mice using one of two types of follicles: (1) intact follicles, where transplants included bulbs, and (2) upper follicles, where transplants excluded bulbs. Follicular samples were collected for hematoxylin and eosin staining, immunofluorescence staining for tyrosine hydroxylase (TH, a sympathetic marker) and enzyme-linked immunosorbent assays. At 37 days after implantation in both groups, follicles had entered anagen, with the growth of long hair shafts; tyrosine-hydroxylase-positive nerves were innervating follicles (1.45-fold); and norepinephrine concentrations (2.03-fold) were significantly increased compared to 5 days, but did not return to normal. We demonstrate the survival of intact and upper follicle xenografts and the partial restoration of sympathetic reinnervations of both transplanted follicles.

RESUMO

Background: POLE is a critical biomarker for endometrial cancer (ECs) prognosis and therapeutic decision. However, the immune infiltration and immunotherapy-related gene expression in the tumor microenvironment (TME) of POLE-mutated ECs remain unresolved. Methods: The TCGA database was used to characterize the TME of POLE mutants, which primarily included immune cells and co-expression genes. We used immunohistochemistry (IHC) to determine immune cell abundance and PD-L1 expression in 104 EC tissues, including 11 POLE mutants and 93 wild-type. Results: The bioinformatic study found significant differences in gene expression of the chemokine family, immune-cell markers, and lysozyme in POLE mutants, along with immune response activation. In POLE-mutated ECs, the abundance of CD4+T, CD8+T, M1 macrophages, and dendritic cells increased considerably. Furthermore, POLE mutations may enhance immune cell recruitment or activation and lymphocyte homing in ECs. POLE mutants also had increased expression of immune-checkpoint suppressor genes such as PD-L1, CTLA-4, TIM-3, and others. The tumor mutation burden (TMB) was higher in ECs with POLE mutation. In the validation cohort, we discovered that POLE mutations were related to the immune infiltration abundance of CD8+, CD4+, and Foxp3+ cells and PD-L1 expression by IHC. The prognosis of TCGA-ECs showed that the survival time of the CD8, CD4, PD-L1, or Foxp3 over-expression subgroup of the POLE mutants was significantly prolonged compared to the down-regulation subgroup or the POLE wild-type. Conclusion: The infiltration abundance of CD8+ T, CD4+ T, Foxp3+ T cells, and the expression of PD-L1 harbor crucial value for the prognosis or individualized therapy of POLE-mutated ECs.

RESUMO

By opening the ring of a benzothiazole salt, we provide a sulfur source for the bifunctional reaction of styrene. The ring-opening-recombination reaction of the benzothiazole salt simultaneously constructs new C-S, C-O, and CO bonds after C-S bond breaking. The reaction proceeds in green solvents, requires no transition metal catalyst, and is compatible with many functional groups.

RESUMO

BACKGROUND: Prone position ventilation (PPV) has gradually become an adjuvant treatment to improve oxygenation in patients with acute respiratory distress syndrome. Scientific and comprehensive evaluation of the quality of nursing care for patients with PPV is of great significance to ensure the effectiveness of treatment and patient safety. However, there are no established objective indicators for evaluating the quality of nursing care for patients with PPV. This study intended to identify a set of scientific, systematic and clinically applicable nursing-sensitive quality indicators for the care of patients with PPV. METHODS: Based on the Donabedian structure-process-result theory model, the quality evaluation indicators of nursing care for patients with PPV were preliminarily constructed based on an evidence-based perspective, and two rounds of Delphi surveys were conducted with the purpose of collecting opinions from a panel of independent experts. RESULTS: The questionnaire recovery rates of the two rounds of correspondence were 100.00% and 95.00%, the recovery rates of expert opinions were 80.00% and 26.32%, the expert authority coefficient values were 0.89, and the Kendall coordination coefficient W values were 0.110 and 0.133, respectively. The final nursing-sensitive quality indicators for the care of patients with PPV included 3 first-level indicators, 9 s-level indicators and 29 third-level indicators. CONCLUSION: The constructed nursing-sensitive quality indicators for the care of patients with PPV involve quality supervision during the whole process of PPV from three dimensions: structure, process and results. These indicators have strong operability, reliability, practicability and scientificity and can provide a reference for the quality evaluation and monitoring of nursing care for patients with PPV. IMPLICATIONS FOR NURSING MANAGEMENT: The quality indicators of nursing care for patients with PPV constructed in this research are scientific and reliable, and the content of the quality indicators can better reflect the technical characteristics of special nursing. Nursing managers are encouraged to use these quality indicators to evaluate the quality of clinical nursing care and improve safety for patients with PPV.

RESUMO

Background: Prone position ventilation (PPV) can significantly improve oxygenation index and blood oxygen saturation in most (70%-80%) patients with acute respiratory distress syndrome. However, although PPV is not an invasive procedure, there are many potential PPV-related complications, such as nerve compression, crush injury, venous stasis (e.g., facial oedema), pressure sores, retinal damage, vomiting, and arrhythmia, with an incidence of up to 56.9%. Nursing managers have focused on reducing the occurrence of PPV-related complications and improving safety. Objective: To construct a prone ventilation management scheme for patients with severe coronavirus disease 2019 (COVID-19) and analyse its application effect. Methods: Based on a previous evidence-based study combined with the COVID-19 Diagnosis and Treatment Protocol (Trial Edition 9), a prone ventilation management protocol for severe COVID-19 was formulated and applied to COVID-19 patients in the intensive care unit of a designated hospital. A prospective self-control study was used to compare changes in the oxygenation index and other outcome indicators before and after the intervention. Results: The oxygenation index of patients after intervention (321.22 ± 19.77 mmHg) was significantly higher (p < 0.05) than before intervention (151.59 ± 35.49 mmHg). The difference in oxygenation index in different prone position ventilation durations was statistically significant (p < 0.05). Nursing quality evaluation indicators showed that the implementation rate of gastric residual volume assessment was 100% and the incidence of occupational exposure and cross-infection was 0%; the incidences of pressure ulcers, drug extravasation, and facial oedema were 13.64% (3/22), 4.54% (1/22), and 4.54% (1/22), respectively. The incidence of unplanned extubation, aspiration, and falls/falls was 0%.

RESUMO

An eco-friendly and efficient extraction method using deep eutectic solvents assisted ultrasound extraction (DESs-UAE) for the polyphenols from Ligustrum robustum was developed. Among the 34 kinds of DESs prepared, tetraethyl ammonium bromide: 1,2,4-butanol (Teab: 1,2,4-But) was proved to be a suitable extraction solvent based on the extraction efficiency. The extraction parameters including temperature, water content, liquid-solid ratio were optimized with response surface methodology (RSM). Under the optimal conditions, the total phenolic content (TPC) and total flavonoid content (TFC) were 101.46 ± 2.96 mg GAE/g DW and 264.17 ± 5.39 mg RE/g DW, respectively. Furthermore, the extraction mechanism of DESs-UAE was investigated by extraction kinetics, molecular dynamic simulation and theory calculations of interaction. In particular, 9 kinds of polyphenols compounds from Ligustrum robustum were firstly identified by UPLC-Q-TOF-MS. Moreover, the recovered polyphenols exhibited significant antioxidant, α-glucosidase inhibition, acetylcholinesterase inhibition and anticancer activity.

RESUMO

Lipid metabolism is closely linked to adiposity. Prader-Willi syndrome (PWS) is a typical genetic disorder causing obesity; however, the distinct lipidomic profiles in PWS children have not been thoroughly investigated. Herein, serum lipidomics analyses were simultaneously explored in PWS, simple obesity (SO), and normal children (Normal). Results indicated that the total concentration of phosphatidylcholine (PC) and lysophosphatidylcholine (LPC) in the PWS group were significantly deceased compared with both the SO and the Normal group. In contrast, compared with the Normal group, there was an overall significant increase in triacylglycerol (TAG) levels in both the PWS and the SO groups, with the highest found in SO group. Thirty-nine and 50 differential lipid species were screened among 3 groups: between obesity (PWS and SO) and the Normal group. Correlation analysis revealed distinct profiles in PWS that was different from other 2 groups. Notably, PC (P16:0/18:1), PE (P18:0-20:3), PE (P18:0-20:4)) showed significant negative correlation with body mass index (BMI) only in the PWS group. PE (P16:0-18:2) showed a negative association with BMI and weight in the PWS group, but significant positive correlation in the SO group; no statistically significant association was found in the Normal group. We also found a significant negative correlation between Blautia genus abundance and several significantly changed lipids, including LPC (14:0), LPC (16:0), TAG (C50:2/C51:9), TAG (C52:2/C53:9), TAG (C52:3/C53:10), and TAG (C52:4/C53:11), but no significant correlation in the Normal group and the SO group. Similarly, in the PWS group, the Neisseria genus was significantly negatively associated with acylcarnitine (CAR) (14:1), CAR (18:0), PE (P18:0/20:3), and PE (P18:0/20:4), and extremely positively associated with TAG (C52:2/C53:9); no obvious correlations were observed in the Normal group and the SO group.

RESUMO

In this study, soy isoflavones-loaded nanoparticles were prepared using rice proteins (RPs) hydrolyzed by four types of enzyme (alcalase, neutrase, trypsin, and flavorzyme). After optimizing the preparation conditions, the encapsulation efficiency (EE) of the nanoparticles ranged from 61.16% ± 0.92% to 90.65% ± 0.19%. The RPs that were hydrolyzed by flavorzyme with a molecular weight of <5 KDa showed better characters on the formation of nanoparticles, and the formed nanoparticles had the highest EE and loading capacity (9.06%), the smallest particle size (64.77 nm), the lowest polymer dispersity index (0.19), and the lowest zeta potential (-25.64 mV).The results of Fourier transform ion cyclotron resonance, X-ray diffraction, and fluorescence spectroscopy showed that the nanoparticles were successfully encapsulated. The study of interaction showed that the formation of nanoparticles may depend mainly on hydrogen bonds, but other interactions, such as hydrophobic interactions and electrostatic interactions, cannot be ignored. After encapsulation, the pH stability, temperature stability, ionic stability, and oxidation resistance of the nanoparticles were enhanced. Moreover, the in vitro release experiment showed that the encapsulated nanoparticles had a certain protective effect on soybean isoflavones. In summary, rice protein hydrolysates are promising carriers for soybean isoflavones.

RESUMO

BACKGROUND: An increasing number of studies persistently demonstrate that prone position ventilation can significantly improve the oxygenation index and blood oxygen saturation for most patients (70-80%) with acute respiratory distress syndrome (ARDS). Studies have also shown that the awake prone position was both safe and effective in helping patients with coronavirus disease 2019 (COVID-19) breathe spontaneously. However, the prone position is not widely adopted when treating patients with COVID-19 or ARDS from other causes. Basic knowledge, positive attitudes, and correct practices among the nursing staff are necessary to increase the use of prone positions, reduce the incidence of complications associated with prone positions, and improve the quality and safety of health care. AIM: This study aimed to investigate the knowledge, attitudes, and practice of prone positioning of patients among intensive care unit (ICU) nurses working in COVID-19 units and provide suggestions for improvement. STUDY DESIGN: ICU nurses were recruited from two designated tertiary hospitals for COVID-19 treatment in Shanghai, China, in April 2022, using convenience sampling. A questionnaire survey focusing on the dimensions of knowledge, attitudes, and practice of the prone position with 42 items, was conducted. RESULTS: A total of 132 ICU nurses participated. The scores on the overall questionnaire and the dimensions of knowledge, attitudes, and practice of prone position were 167.28 (95% CI, 161.70-172.86), 78.35 (95% CI, 76.04-80.66), 32.08 (95% CI, 31.51-32.65), and 56.85 (95% CI, 52.42-61.28) respectively. The overall average score was 79.66% (95% CI, 0.77-0.82). The results of multiple linear regression analysis showed that prior experience in treating patients with COVID-19 and professional titles were related to the level of knowledge, attitudes, and practice of prone position. CONCLUSIONS: The ICU nurses strongly believed in the effectiveness of prone positioning, but their knowledge and practice levels need improvement. The experience in treating patients with COVID-19 and professional titles were related to the level of knowledge, attitudes, and practice of prone position. Nursing managers should ensure that ICU nurses are well trained in prone positioning and help enhance the knowledge and attitudes toward prone positioning to promote its widespread use.
