'It's that camaraderie': Experiences of a Long-COVID peer support group for staff working in health, social care and emergency services.

Health, social care and emergency services staff, continue to feel the impact of Long-COVID. Using quantitative and qualitative methods, this study aims to evaluate the experience of UK health and social care staff who participated in a virtual Long-COVID peer support group between May 2021 and May 2023. The outcome measures (SWEMWBS and PHQ9) show an improvement in post-group scores, suggesting participation in the peer support group is linked to improved wellbeing.

Identifying post-traumatic stress symptom typologies in clinical and non-clinical healthcare staff: a latent profile analysis.

There has been growing concern regarding increasing levels of post-traumatic stress (PTS) symptoms experienced by healthcare workers (HCW) in the UK, particularly following the COVID-19 pandemic. PTS symptom typologies have been investigated in other adult populations using person-centred latent variable approaches, revealing profiles showing differing symptom levels and patterns. We aimed to explore typologies among clinical and non-clinical healthcare staff to elucidate heterogeneity of presentation.

Multi-level meta-analysis of whether fostering creativity during physical activity interventions increases their impact on cognitive and academic outcomes during childhood.

Neuroplasticity research supports the idea that varied practice and new environments promote cognitive engagement and enhance learning. Expanding on a meta-analysis of the effect of physical activity interventions on cognition and academic outcomes, we reviewed and quantified the impact of task and environmental factors that foster creative physical activity. Interventions were considered as fostering creative physical activity to a greater extent if (1) they were varied, (2) relied less on technical acquisition, instruction or demonstration, (3) involved open spaces, props, or open-ended instructions, and (4) involved interactions with peers.

Prostate cancer-Exercise and Metformin Trial (Pre-EMpT): study protocol for a feasibility factorial randomized controlled trial in men with localised or locally advanced prostate cancer.

Background: Evidence from observational studies have shown that moderate intensity physical activity can reduce risk of progression and cancer-specific mortality in participants with prostate cancer. Epidemiological studies have also shown participants taking metformin to have a reduced risk of prostate cancer. However, data from randomised controlled trials supporting the use of these interventions are limited.

Circulating insulin-like growth factors and risks of overall, aggressive and early-onset prostate cancer: a collaborative analysis of 20 prospective studies and Mendelian randomization analysis.

Background: Previous studies had limited power to assess the associations of circulating insulin-like growth factors (IGFs) and IGF-binding proteins (IGFBPs) with clinically relevant prostate cancer as a primary endpoint, and the association of genetically predicted IGF-I with aggressive prostate cancer is not known. We aimed to investigate the associations of IGF-I, IGF-II, IGFBP-1, IGFBP-2 and IGFBP-3 concentrations with overall, aggressive and early-onset prostate cancer.

Methods: Prospective analysis of biomarkers using the Endogenous Hormones, Nutritional Biomarkers and Prostate Cancer Collaborative Group dataset (up to 20 studies, 17 009 prostate cancer cases, including 2332 aggressive cases).

Slow Down: Behavioural and Physiological Effects of Reducing Eating Rate.

Slowing eating rate appears to be an effective strategy for reducing food intake. This feasibility study investigated the effect of eating rate on post-meal responses using functional magnetic resonance imaging (fMRI), plasma gastrointestinal hormone concentrations, appetite ratings, memory for recent eating, and snack consumption. Twenty-one participants (mean age 23 years with healthy body mass index) were randomly assigned to consume a 600 kcal meal at either a "normal" or "slow" rate (6 vs.

Using neuroimaging to investigate the impact of Mandolean® training in young people with obesity: a pilot randomised controlled trial.

Background: Slowing eating rate using the Mandolean® previously helped obese adolescents to self-select smaller portion sizes, with no reduction in satiety, and enhanced ghrelin suppression. The objective of this pilot, randomised trial was to investigate the neural response to food cues following Mandolean® training using functional Magnetic Resonance Imaging (fMRI), and measures of ghrelin, PYY, glucose and self-reported appetite.

Method: Twenty-four obese adolescents (11-18 years; BMI ≥ 95th centile) were randomised (but stratified by age and gender) to receive six-months of standard care in an obesity clinic, or standard care plus short-term Mandolean® training.

Insulin-like growth factor-II in adipocyte regulation: depot-specific actions suggest a potential role limiting excess visceral adiposity.

The IGF system has an important role in growth and development. IGF-II is a recognized fetal growth promoter. However, its physiological postnatal role remains uncertain, although it is maintained in the circulation at a substantially high level throughout life.

Role of IGF-I, IGF-II and IGFBP-3 in lung function of males: the Caerphilly Prospective Study.

Insulin-like growth factors are peptide hormones that have an endocrine role in the development, growth and repair of human tissues including the respiratory tract. To date, only one population study exists which found positive cross-sectional associations with IGF-I and higher lung volumes. We hypothesised that higher IGF-I, IGF-II, IGFBP-3 and IGF molar ratio would be associated with better cross-sectional and longitudinal lung function.

The role of IGF-I, IGF-II, and IGFBP-3 in male cognitive aging and dementia risk: the Caerphilly Prospective Study.

Background: The increasing incidence of cognitive impairment and dementia in an aging population poses a significant burden on healthcare. Consequently, identifying modifiable physiological factors which may influence the onset of cognitive decline are becoming increasingly important. Previous studies have suggested an association between levels of insulin-like growth factors and cognitive function.

Levels of insulin-like growth factor during pregnancy and maternal cancer risk: a nested case-control study.

Previous studies have suggested that pregnancy measures of insulin-like growth factors (IGFs) may be related to breast cancer risk in mothers. IGFs may also be important in cervical cancer etiology. We conducted a nested case-control study (69 breast cancer cases, 151 cervical cancer cases, 443 controls) among mothers of the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort.

The effects of retinoic acid on the insulin-like growth factor axis in primary tissue culture from hyperparathyroidism.

Background: The importance of the IGF system in HPT has been previously demonstrated. Additionally, the role of vitamin A in HPT has been reported. Retinoic acid (RA), a derivative of vitamin A, is a ligand for the IGF II receptor (IGF2R).

Polymorphisms and circulating levels in the insulin-like growth factor system and risk of breast cancer: a systematic review.

We reviewed all English-language articles on associations among circulating levels of the insulin-like growth factors (IGF) and their binding proteins (IGFBP), polymorphisms in their genes, and breast cancer risk. In premenopausal women, five of eight IGF-I studies and four of six IGFBP-3 studies of circulating levels found that women in the highest quantile had more than twice the risk of developing breast cancer of those in the lowest, although in some this effect was only apparent at young ages. In postmenopausal women, however, there was no consistent effect.

Muscle insulin-like growth factor status, body composition, and functional capacity in hemodialysis patients.

Background: Hemodialysis (HD) patients typically have reduced muscle mass and diminished functional capacity. The role of the muscle insulin-like growth factors (IGFs), a principal anabolic system that is involved in protein synthesis and that has downregulation that is implicated in muscle loss in animal models of uremia, has previously not been assessed in vivo in HD patients.

Methods: Seventeen HD patients were compared cross-sectionally with 17 age-, sex-, and body mass index-matched healthy controls.

Insulin-like growth factor (IGF)-independent effects of IGF binding protein-4 on human granulosa cell steroidogenesis.

The ovarian insulin-like growth factor (IGF)/IGF binding protein (IGFBP) system operates to permit maximal stimulation of steroidogenesis in the dominant follicle. In atretic follicles, the predominant IGFBPs are IGFBP-2 and IGFBP-4, which appear to be selectively cleaved in healthy follicles. We have recently demonstrated potent inhibition by IGFBP-4 of both theca and granulosa cell steroid production.

Childhood growth and adult cancer.

Associations between different patterns of childhood growth and later adult health have recently received much attention. Most studies have found higher mortality in shorter people, explained by their higher incidence of cardiorespiratory disease. In this chapter, associations of cancer with markers of growth at different developmental phases - infancy, childhood and puberty - and with final adult height are reviewed.
