RESUMO

Burnout, characterized by exhaustion, reduced accomplishment, and devaluation, can have substantial negative implications for athletes. Notably, researchers continue to examine burnout from multiple perspectives, commonly focusing on stress-, motivation-, or commitment-related factors, with limited efforts to consider these perspectives together. In contrast, this study aimed to assess the utility of these multiple perspectives and the key predictors of burnout in the same athlete sample. Data on burnout, stress, motivation, motivational climate, and sport commitment were gathered from 370 Gaelic games athletes. Separate structural equation models incorporating stress, motivation, and commitment factors as predictors of burnout dimensions were assessed. All models showed adequate fit. However, differences in effect size suggest that stress is more strongly associated with exhaustion, while commitment and motivation showed a stronger relationship with reduced accomplishment and devaluation. Evidence of significant predictors across perspectives also supports an integrated approach and may inform integration efforts and targeted intervention strategies.

RESUMO

Dairy and nondairy plant-based alternative proteins are reported to differentially influence body weight; however, most research has compared plant-based alternatives with isolated dairy proteins rather than a complete milk protein (containing casein and whey). This is notable given that people do not generally consume isolated dairy proteins. Therefore, the present study aimed to investigate the impact of a soy protein isolate (SPI) on factors influencing body weight gain in male and female mice in comparison to skim milk powder (SMP). Based on current knowledge in rodents, we hypothesized that SPI would promote body weight gain compared with SMP. Mice (n = 8 per sex per diet) consumed a moderate-fat diet (35% kcal from fat) containing either SPI or SMP for 8 weeks. Body weight and food intake were measured weekly. Energy expenditure, physical activity, and substrate use were measured using metabolic cages. Fecal energy content was measured with bomb calorimetry. Body weight gain and food intake during the 8-week feeding study was not different in mice consuming either SPI or SMP; however, males had a higher body weight, adiposity, and feed efficiency compared with females (all P < .05). Fecal energy content was approximately 7% higher in both male and female mice fed the SPI diet compared with the SMP diet. Neither protein source affected substrate utilization, physical activity, or energy expenditure. Physical activity in the dark phase trended higher in females compared with males (P = .0732). The present study suggests that the consumption of SPI in the context of a moderate-fat diet has little impact on numerous factors influencing body weight regulation in male and female mice compared with a complete milk protein.

RESUMO

The COVID-19 pandemic resulted in social-distancing measures and the suspension of organised sport globally, and has been shown to have negatively impacted mental health. However, athletes may have experienced reprieve from sport demands, which have previously been linked with maladaptive responses such as burnout and stress. The aims of this study were (1) compare levels of burnout and stress reported by Gaelic games athletes pre- and post-COVID-19 suspension period, (2) explore how athletes utilised and perceived this period and the return to sport, and (3) examine the implications of this for burnout. Participants completed an online questionnaire, which included the athlete burnout questionnaire, perceived stress scale, sport emotion questionnaire, demographic questions, weekly training hours, and other hours for sport (e.g. travel) before Covid-19 (BC-19) and after the Covid-19-induced suspension (AC-19_S). Questions relating to how athletes utilised (e.g. training focus) and perceived (positive/negative impact) the period were included AC-19 S. Data was compared across time-points and we explored predictors of burnout AC-19_S. Ninety-two athletes completed the questionnaire at both time-points. No significant differences in burnout or stress were identified, suggesting the suspension period did not significantly impact these variables. Burnout BC-19, stress AC-19_S, unpleasant emotions about returning to sport and using the period to rest/recover positively predicted burnout AC-19_S. Reduction in other hours across time-points and pleasant emotions about returning predicted lower burnout. Results suggest an athletes' response to a suspension period and subsequent return to sport can impact feelings of burnout, and may have implications for future unanticipated change events.

RESUMO

INTRODUCTION: The aim of this review was to systematically examine the evidence on the relationship between quality of life (QoL) and unmet supportive care needs in patients with lung cancer. METHODS: Six databases were searched for studies published since 2007. Studies were included if they measured QoL using a standardised tool and examined its association with unmet supportive care needs in lung cancer patients. RESULTS: Six studies involving 562 patients were included. Nearly two thirds of the patients had been diagnosed with advanced cancer (Stage III or IV), and the majority had been diagnosed for less than 2 years. There was a negative association between QoL and unmet needs using two different measures (Supportive Care Needs Survey[SCNS] and Cancer Survivors Unmet Needs Survey [CaSUN]). In two studies, the relationship was limited to physical and/or psychological domains. CONCLUSIONS: Unmet supportive care needs are associated with poorer QoL for people with lung cancer: The findings suggest that unmet physical and psychological needs may have the most impact on QoL and reflect the high symptom burden and psychological distress associated with lung cancer. Further work is needed to examine these relationships to identify the services and interventions that address the range of care needs across the disease trajectory.

RESUMO

OBJECTIVE: Informal caregivers of people with lung cancer often experience a substantial care burden and associated negative consequences due to the often-contracted course of the disease. The objective of this review was to systematically examine the evidence on the factors associated with lung cancer caregiver distress. METHODS: Five databases (MEDLINE, CINAHL, EMBASE, PsychINFO and Web of Science) were searched for studies investigating factors associated with distress amongst caregivers of people with lung cancer. Empirical studies published up to July 2020 were included if they measured distress using a valid and reliable measure and examined its association with at least one other factor, with a sample of 50 or more caregivers. RESULTS: Thirty publications describing 27 studies (16 cross-sectional; 6 prospective; 8 intervention) involving 3744 caregivers (primarily spouse or adult child) were included. A narrative synthesis of the findings is presented due to heterogeneity in study design, variables measured and analyses conducted. Patient variables associated with greater distress included: stage of cancer and quality of spousal relationship. Caregiver variables associated with higher distress included: social support, coping strategies and self-efficacy. CONCLUSIONS: Several variables were associated with distress amongst lung cancer caregivers. Understanding these variables could inform the development of interventions that will enable caregivers to care effectively while maintaining their own well-being. Screening for distress among caregivers may identify those caregivers who would benefit from early intervention.
