Objective: We investigated the relationship between respiratory events experienced before and after hospital discharge and developmental outcomes at 6 months corrected age (CA).

Study Design: Preterm infants born between 28-32 weeks gestational age (GA) were studied at 32-36 weeks postmenstrual age (PMA), 36-40 weeks PMA, 3- and 6-months CA. Percentage total sleep time (%TST) with respiratory events (isolated apneas, sequential apneas and periodic breathing (PB)) at each study was calculated. Stepwise multiple linear regressions determined significant predictors of developmental outcomes at 6 months.

Result: %TST with respiratory events at term were significant predictors of language (R = 0.165, β = -0.416) and motor (R = 0.180, β = -0.485) composite scores of the Bayley Scales of Infant Development at 6 months, independent of GA, birth weight and sex.

Conclusions: In clinically stable very preterm infants at term equivalent age, time spent having respiratory events, was related to a reduction in language and motor outcomes at 6 months.

Objective: This integrative review aims to evaluate the efficacy and safety of nebulized tranexamic acid (TXA) in managing hemoptysis, assessing its potential as a non-invasive alternative to traditional invasive procedures.

Methods: An integrative review was conducted in accordance with PRISMA guidelines and was registered on PROSPERO (CRD42024584812). The search included databases such as PubMed, EMBASE, Web of Science, and the Cochrane Central Register of Controlled Trials, encompassing studies published up to August 7, 2024.

Background: The impact of incorporating immune checkpoint inhibitors (ICIs) into standard chemotherapy on the severity and risk of myelosuppression in advanced non-small cell lung cancer (NSCLC) patients remains uncertain.

Methods: We conducted a systematic review and meta-analysis of phase 3 randomized controlled trials (RCTs) that evaluated ICIs in people with NSCLC. A comprehensive search of four databases, PubMed, Web of Science, Embase, and the Cochrane Library, was carried out from inception to 30 October 2023.

Background: After-hours pediatric anesthesia may pose increased risks, with a heightened potential for sudden cardio-respiratory decline. While mortality rates are low in Australia and New Zealand, critical events and morbidity occur more frequently and present ongoing challenges. However, little is known about how trainees are supervised during these high-risk periods.

Background: Iatrogenic pneumothorax is a common complication of diagnostic and therapeutic pulmonary procedures. New guidelines on primary spontaneous pneumothorax suggest ambulatory approaches may be suitable. However, guidance on iatrogenic pneumothorax occurring in patients with impaired lung function, increased age, comorbidity and frailty is lacking, and the safety profile of ambulatory management is not known.
