In this study, we expanded upon the job demands-resources model to assess the role of employees' vitality as an inner resource for their work engagement and job commitment. To assess vitality and related job resources, we developed an index of vitality outside of work and adapted measures of manager autonomy support and organizational support. For job demands, we measured work stress and predicted that each of these four variables would contribute independently to work-related outcomes.

This cohort study investigated the effectiveness of surgical MDT meetings by assessing the predictability of MDT meeting recommendations, the degree that patient management plans are changed by discussion, and the incidence of recommendation implementation.
Methods: Multidisciplinary team meetings at The Queen Elizabeth Hospital in South Australia were audited for upper gastrointestinal (UGI) and colorectal (CR) surgical units from August 2021 to June 2022.
Self-determination theory (Ryan & Deci, 2017) has highlighted the differential roles that intrinsic life goals (for personal growth, close relationships, community connections, and physical health) and extrinsic life goals (i.e., for wealth, image, and status) play in supporting well-being.

We tested these claims using a combination of one-stage and univariate meta-analytic structural equation modeling with moderation ( = 238; = 1,040, = 126,423). In the univariate models, parental autonomy support was linked positively with child well-being, = 0.

Improvements to nutrition and exercise are important, but mental health requires a psychological approach. Self-determination theory finds that autonomy is essential to wellbeing while experiences of being controlled undermine it.

The aim of this study was to investigate whether a document called a question prompt list, containing suggested questions that a patient may like to ask their doctor, improved communication.
Methods: A prospective RCT was conducted from October 2021 to October 2022 at The Queen Elizabeth Hospital, Adelaide, Australia.
Background: Communication is the foundation of a strong doctor-patient relationship. Holistic care of the patient involves good communication and empathy. There are various tools and interventions aimed at increasing the Surgeon's performance, but these have the drawback of heavy cost and time commitments.

In two studies we applied the framework of Self-Determination Theory (SDT) to examine people's autonomous (volitional) and controlled (pressured) motivation for understanding and managing their finances, as well as their amotivation (lack of motivation) for doing so, and the differential associations these motives have with financial knowledge and financial well-being. American participants (Study 1, = 516; Study 2, = 534) completed detailed demographic surveys and questionnaires assessing the financial variables of interest.

An evidence base spanning nearly 30 years indicates that focusing on intrinsic goals (such as for growth, relationships, community giving, and health) promotes well-being, whereas a focus on extrinsic goals (such as for wealth, fame, and beauty) deters well-being. Yet, the evidence base contains exceptions, and some authors have argued that focusing on extrinsic goals may not be universally detrimental.
View Article and Find Full Text PDFIntroduction: Non-alcoholic fatty liver disease (NAFLD) is characterised by accumulation of triglycerides and cholesterol within the liver and dysregulation of specific hepatic cytochrome P450 (CYPs) activity. CYPs are involved in the metabolism of endogenous and exogenous chemicals. Hepatic CYP activity is dysregulated in human studies and animal models of a Western diet (WD) or low birth weight (LBW) independently, but the additive effects of LBW and postnatal WD consumption are unknown.
View Article and Find Full Text PDFPurpose: Ten percent of pregnancies are affected by intrauterine growth restriction (IUGR), and evidence suggests that affected neonates have reduced activity of hepatic cytochrome P450 (CYP) drug metabolising enzymes. Given that almost all pregnant individuals take medications and additional medications are often required during an IUGR pregnancy, we aimed to determine the impact of IUGR on hepatic CYP activity in sheep fetuses and pregnant ewes.
Methods: Specific probes were used to determine the impact of IUGR on the activity of several CYP isoenzymes (CYP1A2, CYP2C19, CYP2D6 and CYP3A) in sheep fetuses and pregnant ewes.
Restriction of fetal substrate supply has an adverse effect on surfactant maturation in the lung and thus affects the transition from in utero placental oxygenation to pulmonary ventilation ex utero. The effects on surfactant maturation are mediated by alteration in mechanisms regulating surfactant protein and phospholipid synthesis. This study aimed to determine the effects of late gestation maternal undernutrition (LGUN) and LGUN plus fetal glucose infusion (LGUN+G) compared to Control on surfactant maturation and lung development, and the relationship with pulmonary blood flow and oxygen delivery ( ) measured by magnetic resonance imaging (MRI) with molecules that regulate lung development.

The thorough and explicit measurement and visualization of the right and left heart output during this transition has not been previously accomplished. We combined 4D flow MRI (dynamic volumetric blood flow measurements) and T2 relaxometry (oxygen delivery quantification) in surgically instrumented newborn piglets to assess the DA.

Due to systematic disadvantage and inter-generational trauma, Indigenous Australians may be less likely to have satisfied basic psychological needs (autonomy, competence, and relatedness). When people are need-thwarted, they may engage in compensatory behaviours to feel better in the short-term.

Artificial placenta technology aims to extend gestation ex utero in order to allow the lungs additional time to develop prior to entering an air-breathing environment. We compared the haemodynamics and cerebral oxygenation of piglets in the immediate period post-oxygenator (OXY) transition against both paired in utero measures and uniquely against piglets transitioned onto mechanical ventilation (VENT).

We investigated the effects of increased uterine artery blood flow mediated by resveratrol on fetal growth, haemodynamics, blood pressure regulation and oxygenation in pregnant sheep. What is the main finding and its importance? Fetuses from resveratrol-treated ewes were significantly larger and exhibited a haemodynamic profile that might promote peripheral growth.

Our aim was to explore whether the sheep placenta expresses androgen receptor (AR) isoforms and determine if the differential expression of AR protein isoforms is altered by maternal asthma. Four known AR isoforms were detected (AR-FL, AR-v1, AR-v7, and AR-45), and their expression and subcellular distribution was altered in the presence of maternal allergic asthma.

Grounded in self-determination theory, the present study proposes a theoretical model for how mindfulness supports different forms of human motivation, and then tests this via meta-analysis. A systematic review identified 89 relevant studies ( = 25,176), comprising 104 independent data sets and 200 effect sizes.
