Abstract Aim To examine the status quo and influencing factors of sleep quality and work engagement of nurses participating in COVID‐19 during the post‐epidemic era and to study the relationship between them. Design We conducted a cross‐sectional survey and correlational and predictive logic to determine the association between sleep quality and work engagement among nurses in Shanghai during the post‐epidemic era. Methods This design involved 1060 frontline nurses in Shanghai. The Pittsburgh Sleep Quality Index questionnaire and the Utrecht Work Engagement Scale‐9 scales were used for data collection. Results This study found that the sleep quality of frontline nurses was impaired and the nurses with poor sleep accounted for 48.20% during the post‐epidemic era. The work engagement of frontline nurses was at the medium level. Factors affecting nurses' sleep quality were the number of nurse night shifts, family support and nurse health. The factors affecting the nurse work engagement were monthly income, profession title, family support and self‐health status. There was a positive correlation between nurses' sleep quality and work engagement.

This was a non‐blinded, single‐centre, randomized, controlled clinical trial that compared the effectiveness of direct observation of procedural skills (DOPSs)with traditional assessment methods in pressure injury (PI) care skills. The study population included 82 nursing professionals randomly assigned to the study group (n = 41) and the control group (n = 41). Both groups of nurses underwent a 6‐month training in PI care skills and were subsequently evaluated. The main outcome variables were the PI skill operation scores and theoretical scores. Secondary outcome variables included satisfaction and critical thinking abilities. Independent sample t‐tests and chi‐square tests were used to assess differences between the two groups of nurses. The results showed no statistically significant difference in PI skill operation scores between the two groups of nurses (p > 0.05). When comparing the PI theoretical scores, the study group scored higher than the control group, and this difference was statistically significant (p < 0.05). In terms of satisfaction assessment, the study group and the control group showed differences in improving self‐directed learning, enhancing communication skills with patients, improving learning outcomes and increasing flexibility in clinical application (p < 0.05). When comparing critical thinking abilities between the two groups of nurses, there was no statistically significant difference at the beginning of the training, but after 3 months following the training, there was a statistically significant difference between the two groups (p < 0.01).The results indicated that the DOPS was effective in improving PI theoretical scores, increasing nurse satisfaction with the training and enhancing critical thinking abilities among nurses.

Background: Delirium is one of the most common complications in critically ill children. Once delirium occurs, it will cause physical and psychological distress in children and increase the length of their ICU stay and hospitalization costs. Understanding the risk factors for delirium in critically ill children can help develop targeted nursing interventions to reduce the incidence of delirium. Aims: To investigate the incidence and the risk factors of delirium in the paediatric intensive care unit (PICU). Study design: We performed a prospective observational study in critically ill patients in the PICU between February and July 2020. Delirium was diagnosed by the Cornell Assessment of Paediatric Delirium (CAPD) and the Richmond Agitation Sedation Scale and analysed via univariate analysis and multivariate logistic regression to determine the independent risk factors of delirium in critically ill children. Results: The study enrolled 315 patients ranging in age from 1–202 (65.3–54.3) months, with 56.2% (n = 177) being male. The incidence of delirium was 29.2% (n = 92) according to CAPD criteria. Among them, 33 cases (35.9%) were of hyperactive delirium, 16 cases (17.4%) were of hypoactive delirium, and 43 cases (46.7%) were of mixed delirium. By using stepwise logistic regression, the independent risk factors of delirium included mechanical ventilation (odds ratio [OR], 11.470; 95% confidence interval [CI], 4.283–30.721), nervous system disease (OR, 5.596; 95%CI, 2.445 to 12.809), developmental delay (OR, 5.157; 95% CI, 1.990–13.363), benzodiazepine (OR, 3.359; 95% CI 1.278–8.832), number of catheters (OR, 1.918; 95% CI, 1.425 to 2.582), and age (OR, 0.985; 95% confidence interval CI, 0.976–0.993). Conclusions: Delirium is a common complication in the PICU. The independent risk factors include mechanical ventilation, nervous system disease, developmental delay, benzodiazepines, higher number of catheters, and younger age. This study may help develop intervention strategies to reduce the incidence of delirium in critically ill children by targeting modifiable risk factors. Relevance to Clinical Practice: Recommendations for practice include paying attention to high‐risk children in the ICU who are prone to delirium, removing influencing factors as soon as possible, and providing targeted nursing interventions.

2 nanofibers and nanotubes were synthesized by electrospinning method. Magnetization measurement indicates that the 2 nanofibers and nanotubes annealed in air at 500°C exhibit the room-temperature ferromagnetism and the ferromagnetism of nanotubes is stronger than the nanofibers. Selected area electron diffraction, X-ray diffraction and Raman measurements show that all the samples possess a typical rutile structure and no other impurity phases are observed. The results of the Raman spectra also indicate that there are lots of defects existing in the fabricated samples. The observed room-temperature ferromagnetism in 2 nanofibers and nanotubes possibly originates from oxygen vacancies. The field cooled (FC) and zero-field-cooled (ZFC) magnetization curves indicate that the Curie temperature TC is above 300 K. SnO2 nanofibers and nanotubes were synthesized the electrospinning method. The observed room-temperature ferromagnetism originates from surface defects. [ABSTRACT FROM AUTHOR]

A decomposed method of containership stowage plan in full route is put forward, which is selection of bays and sorting of containers in bays. As space is limited, the main focus is how to sort the containers of different weights belonging to the same port in the bay. Optimization model is established based on the objective functions of minimizing the metacentric height and heel moment, and the sort of containers of different weights is regarded as assignment problem, and tabu search algorithm is used to solve this problem. A case certifies the feasibility of the model and algorithm. The model for container stowage problem is practical and optimal. [ABSTRACT FROM AUTHOR]

Containership stowage plan problem is an NP-hard problem. The problem is decomposed into two sub-problems, namely, pre-stowage plan and arranging containers of bays in order to reduce the computational complexity. Firstly, pre-stowage problem is regarded as packing problem, ship-bays on the board of vessel are regarded as bins, and the number of cells at each bay is taken as capacities of bins, containers with different characteristics (homogeneous containers group) are treated as items packed. At this stage, there are two objective functions: one is minimizing the number of bays packed by containers and the other is minimizing the number of rehandles. Secondly, containers assigned to each bays at first stage are allocated to special slot, and the objective functions are to minimize the metacentric height, heel and rehandles. The taboo search heuristics algorithm is used to solve the sub-problem. The main focus is on the first sub-problem. A practical case certifies the feasibility of the model and the algorithm.

C/EBP homologous protein (CHOP) triggers the death of multiple cancers via endoplasmic reticulum (ER) stress. However, the function and regulatory mechanism of CHOP in liver cancer remain elusive. We have reported that late endosomal/lysosomal adapter, mitogen-activated protein kinase and mTOR activator 5 (LAMTOR5) suppresses apoptosis in various cancers. Here, we show that the transcriptional and posttranscriptional inactivation of CHOP mediated by LAMTOR5 accelerates liver cancer growth. Clinical bioinformatic analysis revealed that the expression of CHOP was low in liver cancer tissues and that its increased expression predicted a good prognosis. Elevated CHOP contributed to destruction of LAMTOR5-induced apoptotic suppression and proliferation. Mechanistically, LAMTOR5-recruited DNA methyltransferase 1 (DNMT1) to the CpG3 region (-559/-429) of the CHOP promoter and potentiated its hypermethylation to block its interaction with general transcription factor IIi (TFII-I), resulting in its inactivation. Moreover, LAMTOR5-enhanced miR-182/miR-769 reduced CHOP expression by targeting its 3'UTR. Notably, lenvatinib, a first-line targeted therapy for liver cancer, could target the LAMTOR5/CHOP axis to prevent liver cancer progression. Accordingly, LAMTOR5-mediated silencing of CHOP via the regulation of ER stress-related apoptosis promotes liver cancer growth, providing a theoretical basis for the use of lenvatinib for the treatment of liver cancer., (© 2024.

Poly (ADP-ribose) polymerase 1 (PARP1) is a DNA-binding protein that is involved in various biological functions, including DNA damage repair and transcription regulation. It plays a crucial role in cisplatin resistance. Nevertheless, the exact regulatory pathways governing PARP1 have not yet been fully elucidated. In this study, we present evidence suggesting that the hepatitis B X-interacting protein (HBXIP) may exert regulatory control over PARP1. HBXIP functions as a transcriptional coactivator and is positively associated with PARP1 expression in tissues obtained from hepatoma patients in clinical settings, and its high expression promotes cisplatin resistance in hepatoma. We discovered that the oncogene HBXIP increases the level of PARP1 m 6 A modification by upregulating the RNA methyltransferase WTAP, leading to the accumulation of the PARP1 protein. In this process, on the one hand, HBXIP jointly activates the transcription factor ETV5, promoting the activation of the WTAP promoter and further facilitating the promotion of the m 6 A modification of PARP1 by WTAP methyltransferase, enhancing the RNA stability of PARP1. On the other hand, HBXIP can also jointly activate the transcription factor CEBPA, enhance the activity of the PARP1 promoter, and promote the upregulation of PARP1 expression, ultimately leading to enhanced DNA damage repair capability and promoting cisplatin resistance in hepatoma. Notably, aspirin inhibits HBXIP, thereby reducing the expression of PARP1. Overall, our research revealed a novel mechanism for increasing PARP1 abundance, and aspirin therapy could overcome cisplatin resistance in hepatoma., (© 2024.

The practical utilization of the hydrogen evolution reaction (HER) necessitates the creation of electrocatalysts that are both efficient and abundant in earth elements, capable of operating effectively within a wide pH range. However, this objective continues to present itself as an arduous obstacle. In this research, we propose the incorporation of sulfur vacancies in a novel heterojunction formed by MoS 2 @CoS 2 , designed to exhibit remarkable catalytic performances. This efficacy is attributed to the advantageous combination of the low work function and space charge zone at the interface between MoS 2 and CoS 2 in the heterojunction. The MoS 2 @CoS 2 heterojunction manifests outstanding hydrogen evolution activity over an extensive pH range. Remarkably, achieving a current density of 10 mA cm -2 in aqueous solutions 1.0 M KOH, 0.5 M H 2 SO 4 , and 1.0 M phosphate-buffered saline (PBS), respectively, requires only an overpotential of 48, 62, and 164 mV. The Tafel slopes for each case are 43, 32, and 62 mV dec -1 , respectively. In this study, the synergistic effect of MoS 2 and CoS 2 is conducive to electron transfer, making the MoS 2 @CoS 2 heterojunction show excellent electrocatalytic performance. The synergistic effects arising from the heterojunction and sulfur vacancy not only contribute to the observed catalytic prowess but also provide a valuable model and reference for the exploration of other efficient electrocatalysts. This research marks a significant stride toward overcoming the challenges associated with developing electrocatalysts for practical hydrogen evolution applications.

Objective: To investigate the efficacy and safety of the implantation of phakic anterior chamber intraocular lens (IOL) for high myopia., Methods: A consecutive group of 73 eyes in 41 patients with -7.00 to -30.00 diopters (D) of myopia were implanted., Results: All of 73 eyes were implanted successfully and have been followed-up for 3 m (months). The uncorrected visual acuity was from FC/33 cm to 0.2 pre-operatively and 0.1 to 1.0 3 m post-operatively. The best corrected visual acuity (BCVA) was from 0.05 to 1.0 pre-operatively and 0.1 to 1.0 3 m post-operatively. The post-operative BCVA of every eye was not worse than the pre-operative one. The refractive diopters were from -7.00 to -30.00 D pre-operatively and -6.00 to +2.50 D 3 m post-operatively. There were no significant differences between pre- and 3 m post-operative mean corneal astigmatism (t = 1.751, P = 0.082) and mean intraocular pressure (IOP) (t = 1.181, P = 0.240), respectively. The mean counts of endothelial cells was (2 680 +/- 538)/mm(2) pre-operatively and (2 514 +/- 420)/mm(2) 3 m post-operatively. There was no significant difference (t = 1.182, P = 0.242) though it decreased 6.19%. No severe complications occurred., Conclusions: The implantation of phakic anterior chamber IOL for high myopia is predictable, reversible and controllable with simple manipulation. No severe complication occurred in 3 m post-operatively, and long-time follow-up is still required.
