Respiratory pathogen trends in queensland, australia between 2018 and 2021: A statewide cohort study before and after the initial COVID-19 outbreak.

Background: The SARS-CoV-2 pandemic and accompanying public health measures disrupted the normal transmission of respiratory viral pathogens. Less is known about the effects on bacterial pathogens.

Aims: To assess the impact of public health restrictions on common respiratory pathogens (influenza viruses, respiratory syncytial virus (RSV) and the following bacterial pathogens: Streptococcus pneumoniae (S.

Simultaneous Cardiopulmonary Exercise Testing and Echocardiography for Investigation of Cardiopulmonary Dysfunction in Outpatients: Protocol for a Scoping Review.

Background: Cardiopulmonary dysfunction is a complex process with a broad range of etiologies. Investigations performed either at rest or those that only assess the function of a single organ (heart or lungs) are often insufficient. A simultaneous cardiopulmonary exercise test with stress echocardiography is a new approach to assessing cardiopulmonary dysfunction as it provides anatomical and functional imaging simultaneously while under increasing stress.

Right Ventricular Dysfunction on Transthoracic Echocardiography and Long-Term Mortality in the Critically Unwell: A Systematic Review and Meta-Analysis.

Objective: Right ventricular dysfunction (RVD) is common in the critically ill. To date studies exploring RVD sequelae have had heterogenous definitions and diagnostic methods, with limited follow-up. Additionally much literature has been pathology specific, limiting applicability to the general critically unwell patient.

Outcomes of right heart dysfunction in the acutely and severely unwell: protocol for a prospective, longitudinal observational study using multimodal assessment.

Introduction: The relationship of acute right heart dysfunction (RHD) with long-term cardiopulmonary dysfunction and its' associated morbidity has not been clearly elucidated. We propose a prospective, observational study to assess the natural history of acute RHD using a combination of imaging, functional and qualitative assessment methods, including the recently described combination of simultaneous maximal effort cardiopulmonary exercise testing and stress echocardiography.

Methods And Analysis: We propose a single-centre study of patients ≥18 years admitted to either the intensive care or respiratory close observation units with RHD on transthoracic echocardiography (TTE).

Emergency department presentations during the COVID-19 pandemic in Queensland (to June 2021): interrupted time series analysis.

Objectives: To assess emergency department (ED) presentation numbers in Queensland during the coronavirus disease 2019 (COVID-19) pandemic to mid-2021, a period of relatively low COVID-19 case numbers.

Design: Interrupted time series analysis.

Setting: All 105 Queensland public hospital EDs.

Right ventricular outflow tract Doppler flow analysis and pulmonary arterial coupling by transthoracic echocardiography in sepsis: a retrospective exploratory study.

Introduction: Right ventricular (RV) and pulmonary vascular dysfunction appear to be common in sepsis. RV performance is frequently assessed in isolation, yet its close relationship to afterload means combined analysis with right ventricular outflow tract (RVOT) Doppler and RV-pulmonary arterial (RV-PA) coupling may be more informative than standard assessment techniques. Data on feasibility and utility of these parameters in sepsis are lacking and were explored in this study.

The first Australian experience with ward-based continuous positive airway pressure for COVID-19 respiratory failure: a retrospective cohort study.

We present the first Australian cohort of patients with COVID-19 respiratory failure managed with escalating respiratory support including continuous positive airway pressure (CPAP) on a standard medical ward at a tertiary Sydney hospital during the 2021 COVID-19 Delta variant outbreak. We demonstrate an equivalent mortality to CPAP delivered in intensive care unit and outline our ward structure and management during the pandemic.

Conservative management of traumatic pneumothoraces: A retrospective cohort study.

Objective: Traumatic pneumothoraces (T-PTXs) are traditionally managed with an intercostal catheter (ICC), despite little evidence for this. Success with conservative management of primary spontaneous PTX has been demonstrated, and our ED has adopted a conservative approach where safe for all PTX.

Methods: We reviewed all T-PTXs at our institution over a 7-year period to assess outcomes of those conservatively managed and compare with those who received an ICC.

Conservative versus invasive management of secondary spontaneous pneumothorax: a retrospective cohort study.

Aim: Hospitalization, often with intervention, is the recommended management algorithm by multiple international respiratory societies for management of a secondary spontaneous pneumothorax (SSP). Over recent years we adopted a conservative approach to SSPs. We undertook a retrospective cohort study of SSP to establish the safety profile of a conservative approach for these previously unstudied patients.

An atypical pneumonia.

We describe a patient with underlying HIV presenting with progressive respiratory distress and acute renal failure. A unifying diagnosis of microscopic polyangiitis was made. Following immunosuppression induction with plasma exchange and intravenous corticosteroid and subsequent maintenance immunosuppression with intravenous cyclophosphamide in conjunction with renal replacement therapy he achieved remission.

Melioidosis and idiopathic pulmonary hemosiderosis: a cast-iron case.

Melioidosis is an infection with clinical importance in northern Australia due to the high associated mortality despite appropriate therapy. This report presents a case of acute pulmonary melioidosis on a background remarkable for the absence of typical risk factors for infection, but the presence of a high iron pulmonary microenvironment consequent to idiopathic pulmonary hemosiderosis. In light of recent genetic analysis of Burkholderia pseudomallei, we postulate that the patient inadvertently provided a high-substrate environment for the iron-scavenging ability of B.

Early recognition and management of laryngeal fracture: a case report.

Background: Laryngeal fracture is a rare condition that can lead to significant problems with airway patency, voice production, and swallowing. Conflict in the literature exists regarding the most suitable way to manage this injury.

Case Report: We present the case of a 29-year-old Caucasian man who sustained a displaced fracture of the thyroid cartilage due to blunt trauma.

Conservative versus invasive treatment of primary spontaneous pneumothorax: a retrospective cohort study.

Aim: The best management of primary spontaneous pneumothorax is unclear. Conservative treatment has been proposed, but no studies comparing conservative with invasive management have been carried out where pneumothorax size has been numerically quantified. This study aimed to evaluate the feasibility of conservative management for primary spontaneous pneumothoraces of any size.
