Darcy number effects on natural convection around a porous cylinder in L-shaped enclosure using Lattice Boltzmann method.

This study numerically evaluates fluid flow and natural convection heat transfer of a porous square cylinder in an L-shaped enclosure using the Lattice Boltzmann method. Three layouts along vertical and horizontal centrelines are explored, investigating the effects of Rayleigh number (Ra) (10 ≤ Ra ≤ 10), Darcy number (Da) (10 ≤ Da ≤ 10), and cylinder size. Results show that increasing Rayleigh numbers enhances heat transfer, with higher Mean Nusselt number (Nu) values observed.

Major psychiatric comorbidity among the critically ill: a multi-centred cohort study in Queensland.

Background: Although comorbid medical diseases are important determinants of outcome among the critically ill, the role of psychiatric comorbidity is not well defined. The objective of this study was to determine the occurrence of psychiatric comorbidity and its effect on the outcome of patients admitted to adult intensive care units (ICU) in Queensland.

Methods: Admissions among adults to 12 ICUs in Queensland during 2015-2021 were included and clinical and outcome information was obtained through linkages between the ANZICS Adult Patient Database, the state-wide Queensland Hospital Admitted Patient Data Collection, and death registry.

Serum chloride concentration and outcomes in adults receiving intravenous fluid therapy with a balanced crystalloid solution or 0.9% sodium chloride.

Purpose: To determine whether there is an interaction between baseline serum chloride concentration and pH and treatment effects in Intensive Care Unit (ICU) patients receiving intravenous fluid therapy with balanced solution versus 0.9% sodium chloride (saline).

Methods: A secondary analysis of a randomized controlled trial in which patients were divided into cohorts according to quartiles of baseline serum chloride concentration and pH.

Waiting to be discharged from intensive care units: Key factors shaping patient and family experiences.

Objectives: To explore the factors that facilitate and hinder intensive care unit (ICU) discharge processes related to patients and their family members.

Methods: This was a qualitative exploratory study conducted in three regional adult ICUs in Queensland, Australia. Data were collected through semi-structured interviews with patients and their family members (or patient representatives) in addition to daily reflections based on direct observation.

Tracking Outcomes Post Intensive Care: Findings of a longitudinal observational study.

Background: Many intensive care unit (ICU) survivors experience new or worsening impairments, termed post-intensive care syndrome. Substantial investment has been made in identifying patients at risk and developing interventions, but evidence remains equivocal. A more nuanced understanding of risk and outcomes is therefore warranted.
