Abstract

Aim: To determine prevalence, predictors and change over time of nurses' and student nurses' mental health and well‐being, and explore nurses' perceptions, barriers and enablers of well‐being. Design: Longitudinal mixed‐methods survey. Methods: Forty‐nine students and registered nurses participated from Victoria, Australia. Data were collected from December 2019 to July 2020. Validated psychometrics and free‐text response questions were employed. Analysis used latent growth curve modelling, Pearson product‐moment correlations and thematic analysis. Results: A strong positive correlation was found between self‐determination and work well‐being, and a strong negative correlation between work well‐being and flight risk. Several moderate relationships were found; a moderate positive correlation between work well‐being and nurse manager ability, leadership and support, and a moderate negative correlation between burnout and staffing and resource adequacy. Collegial nurse–physician relationships deteriorated. Three themes, physical health, psychological well‐being and social connection, were identified as important for nurses' well‐being.

Abstract

Objective: To assess lifestyle and pharmacological interventions aiming to delay type 2 diabetes mellitus (T2DM) in prediabetes. Methods: We searched the Cochrane Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, PsycINFO, Web of Science, BIOSIS and LILACS databases, examined reference lists and contacted authors. We included randomised controlled trials (RCTs) on both lifestyle and medication interventions in prediabetes. These studies were at least 12 month duration and aimed to delay T2DM. Results: Four studies investigating lifestyle and medication with a total of 5,196 participants were identified. There was a high risk of bias in the studies and the interventions utilised varied considerably; thus, meta-analysis was not undertaken. The comparison between lifestyle and medication interventions was largely dependent on the intensity of the lifestyle program while we could not adequately assess their effects on cardiovascular morbidity. Adverse events with metformin and acarbose were common. Conclusion: There is substantial evidence that intensive lifestyle programs and medications delay T2DM in impaired glucose tolerance though it remains unclear which is more effective. Implications: Both interventions seem to be able to delay T2DM. However, both have issues with adherence and side effects and more RCTs are required. Key words: Diabetes mellitus, Type 2, prediabetic state, prevention and control, lifestyle intervention, pharmacological intervention.

Abstract

Systemic infection produces a highly regulated set of responses such as fever, anorexia, adipsia, inactivity, and cachexia, collectively referred to as sickness behavior. Although the expression of sickness behavior requires immune-brain communication, the mechanisms by which peripheral cytokines signal the brain are unclear. Several mechanisms have been proposed for neuroimmune communication, including the interaction of cytokines with peripheral nerves. A critical role has been ascribed to the vagus nerve in mediating sickness behavior after intraperitoneally delivered immune activation, and converging evidence suggests that this communication may involve neurochemical intermediaries afferent and/or efferent to this nerve. Mice lacking functional CC[K.sub.2/gastrin] receptors (CC[K.sub.2]KO) and wild-type (WT) controls were administered LPS (50, 500, or 2,500 [micro]g/kg; serotype 011l:B4; ip). Results indicate a role for CC[K.sub.2] receptor activation in the initiation and maintenance of LPS-induced sickness behavior. Compared with WT controls, CC[K.sub.2]KO mice were significantly less affected by LPS on measures of body temperature, activity, body weight, and food intake, with the magnitude of effects increasing with increasing LPS dose. Although activation of CC[K.sub.2] receptors at the level of the vagus nerve cannot be excluded, a possible role for these receptors in nonvagal routes of immune-brain communication is suggested. cholecystokinin; lipopolysaccharide; infection; vagus; fever
