Towards an empathic hidden curriculum in medical school: A roadmap.

The "hidden curriculum" in medical school includes a stressful work environment, un-empathic role models, and prioritisation of biomedical knowledge. It can provoke anxiety and cause medical students to adapt by becoming cynical, distanced and less empathic. Lower empathy, in turn, has been shown to harm patients as well as practitioners.

The value of healthcare worker support strategies to enhance wellbeing and optimise patient care.

The World Health Organization has recognised the impact of the SARS-CoV-2 pandemic on healthcare worker (HCW) mental health and wellbeing. Anticipating these effects locally, we developed strategies to support our team, to equip them to care for themselves as well as our patients. We implemented a series of interventions to increase staff support, highlighting the importance of team and individual morale.

A CEACAM6-High Airway Neutrophil Phenotype and CEACAM6-High Epithelial Cells Are Features of Severe Asthma.

Severe asthma represents a major unmet clinical need; understanding the pathophysiology is essential for the development of new therapies. Using microarray analysis, we previously found three immunological clusters in asthma: Th2-high, Th17-high, and Th2/17-low. Although new therapies are emerging for Th2-high disease, identifying molecular pathways in Th2-low disease remains an important goal.

TH2 and TH17 inflammatory pathways are reciprocally regulated in asthma.

Increasing evidence suggests that asthma is a heterogeneous disorder regulated by distinct molecular mechanisms. In a cross-sectional study of asthmatics of varying severity (n = 51), endobronchial tissue gene expression analysis revealed three major patient clusters: TH2-high, TH17-high, and TH2/17-low. TH2-high and TH17-high patterns were mutually exclusive in individual patient samples, and their gene signatures were inversely correlated and differentially regulated by interleukin-13 (IL-13) and IL-17A.

Lung clearance index in adults with non-cystic fibrosis bronchiectasis.

Background: Lung clearance index (LCI) is a measure of abnormal ventilation distribution derived from the multiple breath inert gas washout (MBW) technique. We aimed to determine the clinical utility of LCI in non-CF bronchiectasis, and to assess two novel MBW parameters that distinguish between increases in LCI due to specific ventilation inequality (LCIvent) and increased respiratory dead space (LCIds).

Methods: Forty-three patients with non-CF bronchiectasis and 18 healthy control subjects underwent MBW using the sulphur hexafluoride wash-in technique, and data from 40 adults with CF were re-analysed.

Abdominal pain in adults with cystic fibrosis.

Abdominal pain is a common symptom in individuals with cystic fibrosis (CF). As prognosis has improved, CF has changed from a pediatric disease to the current situation wherein most people with CF are adults. With improved survival, the spectrum of pathologies causing abdominal pain in CF has shifted.

Increased expression of immunoreactive thymic stromal lymphopoietin in patients with severe asthma.

Background: Thymic stromal lymphopoietin (TSLP) is a cytokine implicated in the pathophysiology of asthma through 2 distinct pathways: a TSLP-OX40 ligand (OX40L)-T cell axis and a TSLP-mast cell axis. Whether these pathways are active in human asthma is unknown.

Objective: We sought to investigate whether mucosal TSLP protein expression relates to asthma severity and distinct immunologic pathways.

The tissue microlocalisation and cellular expression of CD163, VEGF, HLA-DR, iNOS, and MRP 8/14 is correlated to clinical outcome in NSCLC.

Background: We have previously investigated the microlocalisation of M1 and M2 macrophages in NSCLC. This study investigated the non-macrophage (NM) expression of proteins associated with M1 and M2 macrophages in NSCLC.

Methods: Using immunohistochemistry, CD68(+) macrophages and proteins associated with either a cytotoxic M1 phenotype (HLA-DR, iNOS, and MRP 8/14), or a non-cytotoxic M2 phenotype (CD163 and VEGF) were identified.

Tumour necrosis factor-alpha expression in tumour islets confers a survival advantage in non-small cell lung cancer.

Background: The role of TNFalpha in cancer is complex with both pro-tumourigenic and anti-tumourigenic roles proposed. We hypothesised that anatomical microlocalisation is critical for its function.

Methods: This study used immunohistochemistry to investigate the expression of TNFalpha in the tumour islets and stroma with respect to survival in 133 patients with surgically resected NSCLC.

Chemokine receptor expression in tumour islets and stroma in non-small cell lung cancer.

Background: We have previously demonstrated that tumour islet infiltration by macrophages is associated with extended survival (ES) in NSCLC. We therefore hypothesised that patients with improved survival would have high tumour islet expression of chemokine receptors known to be associated with favourable prognosis in cancer. This study investigated chemokine receptor expression in the tumour islets and stroma in NSCLC.
