Abstract
Background
Organizational justice is pivotal in fostering a fair and supportive workplace culture, which strengthens the connections between managers and nurses, among nurses themselves, and ultimately, between nurses and their patients. Assessing the perceived levels of organizational justice and managerial behaviors can identify key areas for improving nurses’ commitment and loyalty, while simultaneously reducing incidents of workplace bullying.

Purpose
This study aims to investigate how bedside nurses perceive organizational justice, nurse managers’ caring behaviors, and their exposure to workplace bullying. Additionally, it seeks to explore the relationship between organizational justice, nurse managers’ caring behaviors, and nurses’ perceived exposure to workplace bullying.

Methods
A descriptive-correlational study was conducted in the inpatient care unit of a Saudi hospital. A convenience sample of 256 nurses participated, completing the Organizational Justice Questionnaire (OJQ), the Caring Factor Survey: Caring of the Manager (CFS-CM), and the Negative Acts Questionnaire-Revised (NAQ-R). The collected data were analyzed using descriptive statistics and regression analysis.

Results
Descriptive statistics revealed moderate levels of perceived organizational justice and managerial caring behaviors among nurses, alongside low reported exposure to workplace bullying. Significant correlations were found among the studied variables, indicating that higher perceived organizational justice was associated with higher managerial caring and lower workplace bullying (p < 0.05). Mediation analysis demonstrated a significant indirect effect of organizational justice on workplace bullying through the mediating role of nurse managers’ caring behaviors (a×b = -0.0652, p < 0.001). Furthermore, the direct effect of organizational justice on workplace bullying remained significant even when accounting for the mediator (c = -0.5509, p < 0.001).

Conclusion
This study highlights the vital role of organizational justice and managerial caring in cultivating a positive work environment and mitigating workplace bullying. Implementing clear policies and procedures while promoting fairness and equality in resource allocation, decision-making processes, and interactions are essential strategies for fostering positive attitudes and work behaviors among nurses.

Abstract
Background
This study aimed to assess the impact of coronavirus disease 2019 (COVID-19) on hospital service utilization and revenue in Chinese tertiary hospitals and develop an optimal pandemic control strategy (OPCS) for the peak period of the Omicron wave.

Methods
Retrospective data from three Chinese tertiary hospitals (provincial, city, and county level) were analyzed for three phases: pre-outbreak (Jan-Apr 2019), outbreak (Jan-Apr 2020), and post-outbreak (Jan-Apr 2021). OPCS was developed under the guidance of the China government pandemic control policy during post-break phase of COVID-19. A decision-tree model was constructed to compare OPCS to strict pandemic control strategy during outbreak phase for the hospital service utilization and hospital revenue in a provincial tertiary hospital during the Omicron wave.

Results
Outpatient, emergency room (ER) visits, hospitalizations, and intensive care admissions dropped by 33.8–53.4% during the outbreak, with the provincial hospital being the most affected. Hospital revenue also declined, especially for the provincial hospital (40.1%). Post-outbreak, most services recovered, but ER visits remained lower (11.6% decrease for provincial hospital, 46.5% for county hospital). Total income and expenditure decreased, with the provincial hospital experiencing the most significant revenue reduction (45.7%). OPCS showed greater utilization of medical services (31.6 times more outpatient visits; 1.7 times more inpatient days; 3.4% more surgery volume) and higher revenue (¥220.8 million more) compared to the strict pandemic control strategy.

Conclusions
COVID-19 measures were associated with less hospital service utilization and revenue in Chinese tertiary hospitals. The developed OPCS in Chinese tertiary hospitals, focusing on isolating infected inpatients but not shutting down the hospital facilities exposed to virus, could be effective in optimizing hospital service utilization and hospital revenue during the Omicron wave.

Abstract
Background
Despite significant progress in cardiovascular disease (CVD) management, it remains a public health priority and a global challenge. Within the disease process, health care after a cardiovascular event (secondary prevention) is essential to prevent recurrences. Nonetheless, evidence has suggested the existence of gender disparities in CVD management, leaving women in a vulnerable situation. The objective of this study is to identify all available evidence on the existence of gender differences in health care attention after a major adverse cardiovascular event.

Methods
A scoping review following the structure of PRISMA-ScR was conducted. To define the inclusion criteria, we used Joanna Briggs Institute (JBI) population, concept, context framework for scoping reviews. A systematic search was performed in MEDLINE (PubMed), EMBASE and Cochrane. The methods of this review are registered in the International Platform of Registered Systematic Review and Meta-Analysis Protocols (INPLASY) (INPLASY202350084).

Results
The initial search retrieved 3,322 studies. 26 articles were identified manually. After the reviewing process, 93 articles were finally included. The main intervention studied was the pharmacological treatment received (n = 61, 66%), distantly followed by guideline-recommended care (n = 26, 28%) and cardiac rehabilitation (CR) referral (n = 16)”. Literature described gender differences in care and management of secondary prevention of CVD. Women were less frequently treated with guideline-recommended medications and seem more likely to be non-adherent. When analysing guideline recommendations, women were more likely to make dietary changes, however, men were more likely to increase physical activity. Studies also showed that women had lower rates of risk factor testing and cholesterol goals attainment. Female sex was associated with lower rates of cardiac rehabilitation referral and participation.

Conclusions
This review allowed us to compile knowledge on the existence of gender inequalities on the secondary prevention of CVD. Additional research is required to delve into various factors influencing therapeutic disparities, referral and non-participation in CR programs, among other aspects, in order to improve existing knowledge about the management and treatment of CVD in men and women. This approach is crucial to ensure the most equitable and effective attention to this issue.

Published: July 2024

AbstractMany DNA viruses develop various strategies to inhibit cell death to facilitate their replication. However, whether influenza A virus (IAV), a fast-replicating RNA virus, attenuates cell death remains unknown. Here, we report that IAV infection induces TAK1 phosphorylation in a murine alveolar epithelial cell line (LET1) and a murine fibroblastoma cell line (L929). The TAK1-specific inhibitor 5Z-7-Oxzeneonal (5Z) and TAK1 knockout significantly enhance IAV-induced apoptosis, as evidenced by increased PARP, caspase-8, and caspase-3 cleavage. TAK1 inhibition also increases necroptosis as evidenced by increased RIPK1S166, RIPK3T231/S232, and MLKLS345 phosphorylation. Mechanistically, TAK1 activates IKK, which phosphorylates RIPK1S25 and inhibits its activation. TAK1 also activates p38 and its downstream kinase MK2, which phosphorylates RIPK1S321 but does not affect RIPK1 activation. Further investigation revealed that the RIPK1 inhibitor Nec-1 and RIPK1 knockout abrogate IAV-induced apoptosis and necroptosis; re-expression of wild-type but not kinase-dead (KD)-RIPK1 restores IAV-induced cell death. ZBP1 knockout abrogates IAV-induced cell death, whereas RIPK3 knockout inhibits IAV-induced necroptosis but not apoptosis. 5Z treatment enhances IAV-induced cell death and slightly reduces the inflammatory response in the lungs of H1N1 virus-infected mice and prolongs the survival of IAV-infected mice. Our study provides evidence that IAV activates TAK1 to suppress RIPK1-dependent apoptosis and necroptosis, and that RIPK3 is required for IAV-induced necroptosis but not apoptosis in epithelial cells.
Tumor necrosis factor regulates leukocyte recruitment but not bacterial persistence during Staphylococcus aureus craniotomy infection
Authors: Van Roy Zachary , Kielian Tammy 
Published: July 2024

Abstract
Background
Craniotomy is a common neurosurgery used to treat intracranial pathologies. Nearly 5% of the 14 million craniotomies performed worldwide each year become infected, most often with Staphylococcus aureus (S. aureus), which forms a biofilm on the surface of the resected bone segment to establish a chronic infection that is recalcitrant to antibiotics and immune-mediated clearance. Tumor necrosis factor (TNF), a prototypical proinflammatory cytokine, has been implicated in generating protective immunity to various infections. Although TNF is elevated during S. aureus craniotomy infection, its functional importance in regulating disease pathogenesis has not been explored.

Methods
A mouse model of S. aureus craniotomy infection was used to investigate the functional importance of TNF signaling using TNF, TNFR1, and TNFR2 knockout (KO) mice by quantifying bacterial burden, immune infiltrates, inflammatory mediators, and transcriptional changes by RNA-seq. Complementary experiments examined neutrophil extracellular trap formation, leukocyte apoptosis, phagocytosis, and bactericidal activity.

Results
TNF transiently regulated neutrophil and granulocytic myeloid-derived suppressor cell recruitment to the brain, subcutaneous galea, and bone flap as evident by significant reductions in both cell types between days 7 to 14 post-infection coinciding with significant decreases in several chemokines, which recovered to wild type levels by day 28. Despite these defects, bacterial burdens were similar in TNF KO and WT mice. RNA-seq revealed enhanced lymphotoxin-α (Lta) expression in TNF KO granulocytes. Since both TNF and LTα signal through TNFR1 and TNFR2, KO mice for each receptor were examined to assess potential redundancy; however, neither strain had any impact on S. aureus burden. In vitro studies revealed that TNF loss selectively altered macrophage responses to S. aureus since TNF KO macrophages displayed significant reductions in phagocytosis, apoptosis, IL-6 production, and bactericidal activity in response to live S. aureus, whereas granulocytes were not affected.

Conclusion
These findings implicate TNF in modulating granulocyte recruitment during acute craniotomy infection via secondary effects on chemokine production and identify macrophages as a key cellular target of TNF action. However, the lack of changes in bacterial burden in TNF KO animals suggests the involvement of additional signals that dictate S. aureus pathogenesis during craniotomy infection.

Published: July 2024

Abstract
Background
Pregnancy termination is an essential component of reproductive healthcare. In Southern Africa, an estimated 23% of all pregnancies end in termination of pregnancy, against a backdrop of high rates of unintended pregnancies and unsafe pregnancy terminations, which contributes to maternal morbidity and mortality. Understanding the reasons for pregnancy termination may remain incomplete if seen in isolation of interpersonal (including family, peer, and partner), community, institutional, and public policy factors. This study therefore aimed to use a socio-ecological framework to qualitatively explore, in Soweto, South Africa, i) reasons for pregnancy termination amongst women aged 18–28 years, and ii) factors characterising the decision to terminate.

Methods
In-depth interviews were conducted between February to March 2022 with ten participants of varying parity, who underwent a termination of pregnancy since being enrolled in the Bukhali trial, set in Soweto, South Africa. A semi-structured, in-depth interview guide, based on the socioecological domains, was used. The data was analysed using reflexive thematic analysis, and a deductive approach.

Results
An application of the socio-ecological framework indicated that the direct reasons to terminate a pregnancy fell into the individual and interpersonal domains of the socioecological framework. Key reasons included financial dependence and insecurity, feeling unready to have a child (again), and a lack of support from family and partners for the participant and their pregnancy. In addition to these reasons, Factors that characterised the participants’ decision experience were identified across all socio-ecological domains and included the availability of social support and (lack of) accessibility to termination services. The COVID-19 pandemic and resultant lockdown policies also indirectly impacted participants’ decisions through detrimental changes in interpersonal support and financial situation.

Conclusions
Amongst the South African women included in this study, the decision to terminate a pregnancy was made within a complex structural and social context. Insight into the reasons why women choose to terminate helps to better align legal termination services with women’s needs across multiple sectors, for example by reducing judgement within healthcare settings and improving access to social and mental health support.
Maternal dietary diversity and its association with infant birth weight: a healthcare centre based cross-sectional study
Authors: Javadi Maryam , Saffari Fatemeh , Amerzadeh Mohammad , Rafiei Sima 
Published: July 2024

Abstract
Background
Maternal nutrition during pregnancy is essential to fetal growth and producing a healthy child. This study aims to investigate the relationship between maternal dietary diversity and neonatal weight among pregnant women referred to health centers in Qazvin.

Methods
This was a cross-sectional study of 1076 pregnant women referred to healthcare centers affiliated by Qazvin University of Medical Sciences from April to June 2019. The dietary information of study participants was collected by a food frequency questionnaire. It was used to determine their dietary patterns by applying a factor analysis with a varimax rotation using SPSS software, version 20. Regarding the women's Dietary Diversity Score (DDS), women were categorized into two groups: inadequate (DDS < 4) and adequate (DDS ≥ 4) dietary diversity. The primary outcome was birth weight, and a log-binomial model was run to test the association between DSS and birth outcomes in the study population. The analysis was performed using SPSS Statistics for Windows version 20.0.

Results
Study findings revealed that mothers with higher dietary diversity scores were those with normal BMI and normal levels of hemoglobin who had 8–10.9 kg maternal weight gain and were headed by an employed husband (P < 0.05). Furthermore, the risk of low birth weight in newborns of mothers with inadequate dietary patterns was 2.6 times higher (ARR = 95% CI 2.6, 1.4, 5.12) compared to the newborns from mothers with adequate diets.

Conclusion
Insufficient intake of dietary diversity during pregnancy can potentially increase the likelihood of low birth weight in newborns. Thus, we recommend that health system authorities prioritize the planning for healthy nutrition of pregnant mothers in different geographical regions, specifically remote, rural, and deprived areas of the country.

Abstract
Background
Walking impairment is a common disability post acquired brain injury (ABI), with visually evident arm movement abnormality identified as negatively impacting a multitude of psychological factors. The International Classification of Functioning, Disability and Health (ICF) qualifiers scale has been used to subjectively assess arm movement abnormality, showing strong intra-rater and test-retest reliability, however, only moderate inter-rater reliability. This impacts clinical utility, limiting its use as a measurement tool. To both automate the analysis and overcome these errors, the primary aim of this study was to evaluate the ability of a novel two-level machine learning model to assess arm movement abnormality during walking in people with ABI.

Methods
Frontal plane gait videos were used to train four networks with 50%, 75%, 90%, and 100% of participants (ABI: n = 42, healthy controls: n = 34) to automatically identify anatomical landmarks using DeepLabCut™ and calculate two-dimensional kinematic joint angles. Assessment scores from three experienced neurorehabilitation clinicians were used with these joint angles to train random forest networks with nested cross-validation to predict assessor scores for all videos. Agreement between unseen participant (i.e. test group participants that were not used to train the model) predictions and each individual assessor’s scores were compared using quadratic weighted kappa. One sample t-tests (to determine over/underprediction against clinician ratings) and one-way ANOVA (to determine differences between networks) were applied to the four networks.

Results
The machine learning predictions have similar agreement to experienced human assessors, with no statistically significant (p < 0.05) difference for any match contingency. There was no statistically significant difference between the predictions from the four networks (F = 0.119; p = 0.949). The four networks did however under-predict scores with small effect sizes (p range = 0.007 to 0.040; Cohen’s d range = 0.156 to 0.217).

Conclusions
This study demonstrated that machine learning can perform similarly to experienced clinicians when subjectively assessing arm movement abnormality in people with ABI. The relatively small sample size may have resulted in under-prediction of some scores, albeit with small effect sizes. Studies with larger sample sizes that objectively and automatically assess dynamic movement in both local and telerehabilitation assessments, for example using smartphones and edge-based machine learning, to reduce measurement error and healthcare access inequality are needed.

Abstract
Background
Lymphatic malformations are vascular developmental anomalies varying from local superficial masses to diffuse infiltrating lesions, resulting in disfigurement. Patients’ outcomes range from spontaneous regression to severe sequelae notwithstanding appropriate treatment. The current classification guides, in part, clinicians through the decision-making process, prognosis prediction and choice of therapeutic strategies. Even though the understanding of molecular basis of the disease has been recently improved, a standardized management algorithm has not been reached yet.

Results
Here, we report our experience on five children with different lymphatic anomalies of the head and neck region treated by applying a multidisciplinary approach reaching a consensus among specialists on problem-solving and setting priorities.

Conclusions
Although restitutio ad integrum was rarely achieved and the burden of care is challenging for patients, caregivers and healthcare providers, this study demonstrates how the referral to expert centres can significantly improve outcomes by alleviating parental stress and ameliorating patients’ quality of life. A flow-chart is proposed to guide the multidisciplinary care of children with LMs and to encourage multidisciplinary collaborative initiatives to implement dedicated patients’ pathways.
