Coronary artery disease (CAD) is a major cardiovascular disease responsible for high morbidity and mortality worldwide. The major pathophysiological basis of CAD is atherosclerosis in association with varieties of immunometabolic disorders that can suppress oxytocin (OT) receptor (OTR) signaling in the cardiovascular system (CVS). By contrast, OT not only maintains cardiovascular integrity but also has the potential to suppress and even reverse atherosclerotic alterations and CAD. These protective effects of OT are associated with its protection of the heart and blood vessels from immunometabolic injuries and the resultant inflammation and apoptosis through both peripheral and central approaches. As a result, OT can decelerate the progression of atherosclerosis and facilitate the recovery of CVS from these injuries. At the cellular level, the protective effect of OT on CVS involves a broad array of OTR signaling events. These signals mainly belong to the reperfusion injury salvage kinase pathway that is composed of phosphatidylinositol 3-kinase-Akt-endothelial nitric oxide synthase cascades and extracellular signal-regulated protein kinase 1/2. Additionally, AMP-activated protein kinase, Ca 2+ /calmodulin-dependent protein kinase signaling and many others are also implicated in OTR signaling in the CVS protection. These signaling events interact coordinately at many levels to suppress the production of inflammatory cytokines and the activation of apoptotic pathways. A particular target of these signaling events is endoplasmic reticulum (ER) stress and mitochondrial oxidative stress that interact through mitochondria-associated ER membrane. In contrast to these protective effects and machineries, rare but serious cardiovascular disturbances were also reported in labor induction and animal studies including hypotension, reflexive tachycardia, coronary spasm or thrombosis and allergy. Here, we review our current understanding of the protective effect of OT against varieties of atherosclerotic etiologies as well as the approaches and underlying mechanisms of these effects. Moreover, potential cardiovascular disturbances following OT application are also discussed to avoid unwanted effects in clinical trials of OT usages.
ObjectivesThe objectives of this study were to investigate new nurses’ experiences of workplace incivility; verify the mediating role of work ability in the relationship between workplace incivility and job performance and examine the moderating role of career expectations in the relationship between workplace incivility and job performance.DesignThis cross-sectional survey was conducted in China in May 2016.SettingsThe research settings included 54 cities across 29 provinces of China.ParticipantsOf the 903 participants recruited, 696 new nurses (<3 years of nursing experience) agreed to complete the online questionnaire of the study. The effective response rate was 77.1%. The inclusion criteria were voluntary participation, <3 years of nursing experience and recognition as a registered nurse. The exclusion criteria were refusal to participate, >3 years of nursing experience or not recognised as a registered nurse.ResultsNew nurses (60.7%) experienced some level of workplace incivility in the previous year, and it was more frequent among those with higher educational degrees. Work ability mediated the relationship between workplace incivility and job performance, and this relationship was moderated by career expectations.ConclusionIncivility towards new nurses was relatively common in the workplace. Workplace incivility impairs job performance by weakening the work ability of new nurses. Higher career expectations may buffer workplace incivility and contribute to the maintenance of job performance by buffering the detrimental effects of workplace incivility.
Aim This study aimed to (1) assess the current status of Chinese nurses' exposure to workplace violence; (2) identify the cluster of interrelationships between abusive supervision, anxiety and depression symptoms, work ability, and workplace violence in nursing settings; and (3) clarify the functional mechanism among these variables. Methods A cross‐sectional survey was conducted online from September to October 2020 in China. A total of 1,221 valid questionnaires were collected across 100 cities in 31 provinces. Results Approximately 67.57% of participants experienced workplace violence in the past one year, in the types of verbal violence (59.71%), made difficulties (43.16%), mobbing behaviour (26.70%), smear reputation (22.52%), physical violence (11.30%), intimidating behaviour (10.16%) and sexual harassment (4.10%), respectively. Moreover, nurses' exposure to workplace violence was significantly and positively influenced by the perceptions of abusive supervision (β = 0.209, p < .01) and the symptoms of anxiety and depression (β = 0.328, p < .01). Anxious and depressive symptoms partly mediated the association between abusive supervision and workplace violence, which were significantly moderated by work ability (β = −0.021, p < .05). Conclusions Our study assesses the prevalence of the seven types of workplace violence against Chinese nurses. Majority of nurses have experienced different types of workplace violence. Nurses who are abused by their supervisor are more likely to develop poor psychological health than those who are not. Moreover, nurses' positive association of abusive supervision with workplace violence is more notable among nurses with lower work ability. Implications of Nursing Management ‘No abusive supervision, no workplace violence’. A harmonious nursing environment needs to be provided to minimize exposure to workplace violence and mental health threats towards nursing staff, which is a key point for hospital administrators and health policymakers. Essential work ability should be developed to reduce the damage of the abusive supervision and workplace violence against nurses.
