Article Abstract
Hospital-acquired infections (HAIs), also known as nosocomial infections, are illnesses contracted during treatment at a healthcare facility and can result in severe or life-threatening complications. HAIs are caused by microorganisms that exhibit resistance to standard antibiotics. HAIs can lead to severe complications, longer stays, and increased mortality, particularly in vulnerable patients. In our previous study, we demonstrated the ability of an engraved Petri dish, referred to as a "biosimulator," to induce adhesion of non-adherent cells and the microbiome. This paper explores the use of the biosimulator to elucidate the microbiome composition within intensive care units (ICUs) in a hospital setting. The biosimulator, with a nutrient-rich bacterial growth medium, was placed in ICUs for 24 h, then incubated for three days under aerobic and anaerobic conditions. Using 16S rRNA sequencing, we profiled the ICU microbiome from multiple samples. Our findings showed that ICU microbiomes closely mirrored those of patients, with microorganisms in the ICU exhibiting stronger interrelationships than in control conditions. The combined use of the biosimulator and profiling offers an effective approach for analyzing and understanding microbiome changes in healthcare settings, particularly in high-risk areas, such as ICUs.

Pain, Agitation, Delirium, and Iatrogenic Withdrawal Syndrome Management in Children Who Are Critically Ill: Protocol for a European Clinical Practice Guideline Using the Grading of Recommendations Assessment, Development, and Evaluation Approach.

Background: In pediatric intensive care units, pain, sedation, delirium, and iatrogenic withdrawal syndrome (IWS) must be managed as interrelated conditions. Although clinical practice guidelines (CPGs) exist, new evidence needs to be incorporated, gaps in recommendations addressed, and recommendations adapted to the European context.
Objective: This protocol describes the development of the first patient- and family-informed European guideline for managing pain, sedation, delirium, and IWS by the European Society of Paediatric and Neonatal Intensive Care.

Chikungunya virus (CHIKV) typically causes febrile illness and arthralgia. However, severe complications such as encephalitis, rhabdomyolysis, and multiorgan dysfunction are increasingly recognised, particularly during epidemics in endemic regions. We report a case of a 61-year old male presenting with progressive flaccid paraparesis and respiratory failure following febrile illness.

Department of Health Care Policy, Harvard Medical School, Boston, Massachusetts.
Importance: Hospitals have reported growing difficulty in discharging patients in a timely manner, often citing bottlenecks in postacute care. Medicare Advantage plans, now the dominant form of Medicare coverage, may contribute to these delays due to administrative and network constraints, yet national evidence is lacking.
Objective: To quantify changes in hospital length of stay for Medicare Advantage vs traditional Medicare beneficiaries.

Importance: Neonatal intensive care has advanced over recent decades, yet premature birth remains associated with increased neonatal mortality and morbidity.
Objective: To describe health service use, morbidity, and medication needs up to age 5 years in a contemporary cohort of children born preterm.
Design, Setting, And Participants: This population-based cohort study was conducted in British Columbia (BC), Canada, using health service and pharmacy data linked using provincial administrative databases.

Importance: The cost-effectiveness of adding early in-bed cycling to usual physiotherapy among adults receiving mechanical ventilation in the intensive care unit (ICU) compared with usual physiotherapy alone is unknown.
Objective: To evaluate the cost-effectiveness of in-bed cycling plus usual physiotherapy compared with usual therapy alone in the Critical Care Cycling to Improve Lower Extremity Strength (CYCLE) randomized clinical trial.
Design, Setting, And Participants: This trial-based economic evaluation with a 90-day time horizon compared early cycling plus usual physiotherapy vs usual physiotherapy alone from a societal perspective.
