Impaired Cytokine Responses to Live Staphylococcus epidermidis in Preterm Infants Precede Gram-positive, Late-onset SepsisLate-onset sepsis (LOS) with Staphylococcus epidermidis is common in preterm infants, but the immunological mechanisms underlying heightened susceptibility are poorly understood. Our aim is to characterize the ontogeny of cytokine responses to live S. epidermidis in preterm infants with and without subsequent Gram-positive LOS.

Fine-Tuning the Tumour Microenvironment: Current Perspectives on the Mechanisms of Tumour ImmunosuppressionImmunotherapy has revolutionised the treatment of cancers by harnessing the power of the immune system to eradicate malignant tissue. However, it is well recognised that some cancers are highly resistant to these therapies, which is in part attributed to the immunosuppressive landscape of the tumour microenvironment (TME). The contexture of the TME is highly heterogeneous and contains a complex architecture of immune, stromal, vascular and tumour cells in addition to acellular components such as the extracellular matrix. While understanding the dynamics of the TME has been instrumental in predicting durable responses to immunotherapy and developing new treatment strategies, recent evidence challenges the fundamental paradigms of how tumours can effectively subvert immunosurveillance. Here, we discuss the various immunosuppressive features of the TME and how fine-tuning these mechanisms, rather than ablating them completely, may result in a more comprehensive and balanced anti-tumour response.

Fuel feedstock determines biodiesel exhaust toxicity in a human airway epithelial cell exposure modelBiodiesel is promoted as a sustainable replacement for commercial diesel. Biodiesel fuel and exhaust properties change depending on the base feedstock oil/fat used during creation. The aims of this study were, for the first time, to compare the exhaust exposure health impacts of a wide range of biodiesels made from different feedstocks and relate these effects with the corresponding exhaust characteristics.

Parent Carer Quality of Life and Night-Time Attendance in Non-Ambulant Youth with Neuromuscular DisordersTo describe and explore carer quality of life and night-time attendance to their child in parents of non-ambulant youth with Neuromuscular Disorders. A cross-sectional population-based, comprehensive survey including the Adult Carer questionnaire, measures of social context and youths' physical status. Associations between carer-QoL or frequency of parents' night-time attendance with independent variables were explored using linear and logistic regression models, respectively.

Reduced socs1 expression in lung fibroblasts from patients with ipf is not mediated by promoter methylation or mir155The interleukin (IL)-6 family of cytokines and exaggerated signal transducer and activator of transcription (STAT)3 signaling is implicated in idiopathic pulmonary fibrosis (IPF) pathogenesis, but the mechanisms regulating STAT3 expression and function are unknown. Suppressor of cytokine signaling (SOCS)1 and SOCS3 block STAT3, and low SOCS1 levels have been reported in IPF fibroblasts and shown to facilitate collagen production. Fibroblasts and lung tissue from IPF patients and controls were used to examine the mechanisms underlying SOCS1 down-regulation in IPF.

Lung inflammation and simulated airway resistance in infants with cystic fibrosisCystic fibrosis (CF) is characterized by small airway disease; but central airways may also be affected. We hypothesized that airway resistance estimated from computational fluid dynamic (CFD) methodology in infants with CF was higher than controls and that early airway inflammation in infants with CF is associated with airway resistance.

Additional Insulin is Required in Both the Early and Late Postprandial Periods for Meals High in Protein and Fat: A Randomised TrialThe pattern and quantity of insulin required for high protein high fat (HPHF) meals is not well understood. This study aimed to determine the amount and delivery pattern of insulin required to maintain euglycaemia for five hours after consuming a HPHF meal compared to a low protein low fat (LPLF) meal.

Effects of dietary fat and protein on glucoregulatory hormones in adolescents and young adults with type 1 diabetesDietary fat and protein impact postprandial hyperglycaemia in people with type 1 diabetes, but the underlying mechanisms are poorly understood. Glucoregulatory hormones are also known to modulate gastric emptying and may contribute to this effect.

Continuous subcutaneous insulin infusion alters microRNA expression and glycaemic variability in children with type 1 diabetesTo determine whether continuous subcutaneous insulin infusion (CSII) vs. multiple daily injections (MDI) therapy from near-diagnosis of type 1 diabetes is associated with reduced glycaemic variability (GV) and altered microRNA (miRNAs) expression.

Targeted Teacher Education to Improve Primary Preservice Teachers’ Knowledge and Understanding of UV and Effective Sun Protection Measures for ChildrenTeachers are responsible for children at school during peak ultraviolet (UV) times of the day. It is paramount that teachers have knowledge and understanding of UV to effectively protect themselves and their students. The aim of this pilot study was to investigate the effect of a short intervention on preservice teachers’ sun protective behaviours, knowledge and perceived skill to teach sun safety.
