The proposed single-arm study will investigate the feasibility and utility of CLE and radial EBUS for the detection of lung parenchymal abnormalities in people with ILD. The study will establish the diagnostic yield of radial EBUS and CLE in detection of parenchymal abnormalities in patients with radiologic ILD, by comparing these techniques to the gold standard test of histology, as well as high-resolution CT chest imaging. Real-time assessment and recording of video imaging for later, de-identified review will also permit determination of intra-observer and inter-observer variability. Additional secondary outcomes include safety.

Some women have a caesarean section (abbreviated as CS) to have a baby. The safest anaesthetic for this is with an injection in the mother’s back to make her numb from her breasts down which is called epidural or spinal anaesthesia. CS can be categorised as elective (planned) or emergency (unplanned). Elective CS takes place before the onset of labour (uterine contraction), whereas most emergency CS occurs after labour has started. Hypothermia (a low body temperature) is a common problem during elective CS and consequently active warming is recommended. By contrast, hyperthermia (a high body temperature) is a side effect of epidural pain relief during labour and therefore it is possible that hyperthermia is the dominant problem during emergency CS. The temperature changes during emergency CS are not fully understood. It is important to study temperature changes during CS because hypothermia and hyperthermia can cause problems for her or the baby. Some mothers shiver during CS which is an unpleasant side effect that makes it difficult for mothers to hold their babies and breastfeed shortly after birth. What we know so far is shivering during elective CS is caused by hypothermia and is effectively treated with active warming. During emergency CS, however, shivering occurs at normal or increased body temperatures and therefore active warming is likely inappropriate. At present, body temperature is not routinely checked during CS and therefore it is not possible to tailor temperature regulation strategies to individuals’ needs. In this multicentre cohort study, we will investigate how patterns of body temperature change differ between elective and emergency CSs, and how this relates to shivering. We anticipate that this study will highlight the need to routinely measure body temperature during CS and will be a steppingstone towards personalised temperature management strategies during spinal and epidural anaesthesia.

Eggs provide an affordable, digestible and accessible source of many nutrients, including all eleven essential amino acids, vitamin A, E and B12, selenium, choline and iron, and unsaturated fatty acids including omega-3 (primarily DHA and ALA). Egg yolks are also high in cholesterol and are a major source of dietary cholesterol in Australia. There are current gaps in the research supporting egg intake and other associated health effects outside of plasma cholesterol levels, across different populations and age groups. Egg consumption microbiome studies in humans are extremely limited and have previously only focused on overweight postmenopausal women and/or effects on acute plasma choline levels and microbial taxa related to cardiovascular disease. The gut microbiome is thought to be a key component in Trimethylamine N-oxide (TMAO) metabolism, as trimethylamine is produced by gut bacteria from dietary choline, betaine, or L-carnitine, and then converted in the liver to TMAO, which in turn affects hepatic and intestinal lipid metabolism. Previous human studies have not shown egg consumption to affect plasma TMAO concentrations. However, inter-individual differences highlight the need for larger cohorts and more comprehensive assessment of the effects of egg consumption on gut microbiota. The overall aim is to examine the human gut microbiome in response to egg consumption (compared to no egg consumption) and explore other clinical outcomes (i.e., cognition) and potential mediating factors (i.e., inflammation regulation) in younger and older adults. Specifically, the aims are: 1. To assess effects of 6 weeks’ egg consumption on gut microbial composition and how consequent shifts in gut microbiome species and community function differ between age groups. 2. To explore how egg consumption may influence intuitive decision making, interoception, risk-taking and reaction-time 3. To explore how egg consumption may modulate intestinal immunity by altering levels of anti-inflammatory cytokines and other inflammatory markers such as C-reactive protein. 4. To explore the relationship between regular egg consumption, plasma choline, lipo-polysaccharide binding protein, and TMAO and how these levels may modulate or influence any of the above endpoints.

Patient outcomes following an ischaemic stroke are significantly improved by rescuing the ischaemic penumbra, the severely hypoperfused and hypoxic, electrically silent, at-risk brain tissue. ARG-007 offers the potential to reduce neuronal cell death and preserve still viable tissue in the penumbra in patients by disrupting the excitotoxic pathway that a stroke initiates, resulting in potentially enhanced functional recovery. This is a double-blind, randomized, placebo-controlled, study to assess the safety, tolerability, and pharmacokinetics of single ascending doses of ARG-007 in healthy participants at a single site in Australia. The primary objective of this study is to evaluate the safety and tolerability of single escalating doses of ARG-007 in healthy participants for 8 days, administered by intravenous infusion. The secondary objectives are to determine the pharmacokinetic profile and immune response profile of ARG-007 in healthy participants following single dose administration.

This project aims to improve the nutrition of Aboriginal infants. We will evaluate the effect of scheduled breastfeeding peer support for and by Aboriginal women, on breastfeeding initiation and prevalence of exclusive breastfeeding at six weeks, four months and six months post–birth. Our intervention will utilise both face-to-face peer support for and by Aboriginal women and employ innovative aspects such as social media, video & telephone calls by Aboriginal peer workers for a period of six months postnatally.

Inflammatory bowel disease is a chronic and debilitating condition that affects 1 in 250 Australians. As many as 40% of patients with IBD have a concurrent diagnosis of irritable bowel syndrome with either constipation or diarrhoea as a major symptom. Delineating between inflammatory and functional symptoms can make assessment and management difficult in IBD. Concurrent functional symptoms frequentlyresult in unnecessary invasive investigations and even unnecessary escalation in already powerful immunosuppressive therapy. Constipation is the presence of solid or hard stools in the colon that are difficult to pass without significant exertion. They cause stretch, distension and bloating of the bowel which results in pain that can be difficult to differentiate from underlying inflammatory pain in some patients with concurrent IBD. Ulcerative colitis associated constipation is a phenomenon in which active inflammation results in a slowing of colonic motility and worsening of constipation, predominantly higher up in the colon (proximal constipation). This manifests as pain, bloating and discomfort and not only causes symptoms but can also impact the delivery of medications to the colon that rely on normal colonic movements. Intestinal ultrasound (IUS) has been used successfully across many countries to accurately and safely assess inflammatory bowel disease and allow for real-time decision making as a point of care test. It has been shown in small studies to be able to identify colonic contents such as solid or liquid stool, but this has not been formally defined. The ability of IUS to accurately distinguish between proximal faecal loading versus inflammatory pathology would allow a more safe, cost-effective and tailored approach to managing patients in real-time. Hypotheses: 1. IUS accurately and objectively measures proximal constipation in IBD as validated against CT as the reference standard 2. Unrecognised and frequent proximal constipation is a common cause for symptoms in participants with IBD 3. Proactive management of proximal constipation in IBD leads to an improvement in clinical symptoms and IUS parameters

A significant curriculum redevelopment of the teen Mental Health First Aid for Year 7-9 secondary students (tMHFA 7-9) Edition 2 course has occurred with input from multiple curriculum specialists. The course has been piloted with a class of Year 8 students and responses received to the course from students, MHFA Instructors and supervising teachers used to make further minor revisions. This Uncontrolled Trial will allow for sufficient data to be sure the tMHFA 7-9 Edition 3 program is effective, safe and acceptable to schools, students and instructors prior to it being launched by Mental Health First Aid Australia and subsequently evaluated in a planned Randomised Controlled Trial (ACTRN12621001589875).

Despite a dramatic decline in tobacco smoking prevalence, current smoking rates have plateaued and smoking remains the leading cause of preventable diseases and death in Australia. Smoking rates in ICU patients are higher than the general population, offering an opportunity for intervention, especially as there is good evidence that many smokers do consider cessation following an ICU admission. Thus surviving an ICU admission potentially provides a unique opportunity to promote long-term smoking cessation. Whilst smoking cessation interventions have been evaluated in hospital settings, the optimal intervention remains unclear and no studies looking at combination nicotine replacement therapy (NRT) and counselling have been performed specifically in ICU survivors. Our goal is to conduct a randomized controlled trial comparing standard care (ad hoc advice to patients and NRT) to a formal brief counselling intervention in addition to protocolized NRT. The aim is to improve smoking cessation rates in ICU survivors and thus improve their morbidity and mortality.

A large number of people experience long-COVID Symptoms persisting for weeks and months after overcoming the acute illness. Symptoms include chronic fatigue, breathlessness, muscle pain, persistent cough, loss of sense of smell and/or taste. This study aims to explore underlying disease etiology by a series of blood tests and clinical assessment, followed by a staged treatment approach of 2x 6 weeks. After clinical assessment by a trial doctor, eligible participants will receive intervention-1 for a 6-week period, and allocated to one of three groups of intervention in the 2nd 6-week period. This study is exploratory, and will provide important insights for protocol development for a larger cohort study.
