The purpose of this study was to evaluate the accuracy of different scoring systems, including the Acute Physiology and Chronic Health Evaluation (APACHE) II, the Simplified Acute Physiology Score (SAPS) II, the Sequential Organ Failure Assessment (SOFA) score, the Glasgow Coma Scale (GCS) and the Glasgow Coma Scale-Pupils (GCS-P), in predicting in-hospital mortality for critically ill patients after craniotomy.

This was a single-centre retrospective diagnostic study.

The study was conducted in three intensive care units (70 beds) of a teaching hospital.

Adult patients who underwent craniotomy and stayed in the ICU for more than 24 hours were included. Pregnant or lactating women and patients enrolled in other clinical studies were excluded.

Data on demographics, clinical characteristics and scoring systems (APACHE II, SOFA, SAPS II, GCS and GCS-P) were collected. Receiver operating characteristic (ROC) curves were used to assess the predictive accuracy of each scoring system.

Among 1717 patients included, the in-hospital mortality rate was 6.8%. SAPS II (AUC = 0.822) and APACHE II (AUC = 0.819) demonstrated the highest predictive accuracy, followed by GCS-P (AUC = 0.812), GCS (AUC = 0.803) and SOFA (AUC = 0.762). SAPS II and APACHE II significantly outperformed SOFA, while no significant differences were observed among SAPS II, APACHE II, GCS and GCS-P. For patients with supratentorial lesions, APACHE II, SAPS II, GCS and GCS-P showed similar predictive accuracy, all superior to SOFA. For infratentorial lesions, SOFA outperformed GCS and GCS-P. Among patients with cerebrovascular diseases, SOFA had the lowest predictive accuracy, while GCS-P outperformed GCS.

APACHE II, SAPS II, GCS and GCS-P demonstrated comparable predictive accuracy for in-hospital mortality in critically ill post-craniotomy patients, with SOFA being less effective.

Intermittent theta-burst stimulation (iTBS) is a non-invasive brain stimulation technique that has been shown to improve cognition and mood when applied to certain brain structures and regions. Despite research demonstrating that iTBS may have clinical utility in treating cognitive and mood changes, no study has yet been conducted to explore the potential to modulate the neurophysiological changes that can underpin cognitive and mood changes during the menopause transition. Cognitive and psychological symptoms are commonly reported by females experiencing the menopause transition, and it is thought that these symptoms arise due to various neurophysiological, metabolic and endocrinological changes. Despite being common, there is a lack of treatments available for managing these symptoms and a scarcity of data regarding the mechanisms by which they occur.

The aim of this 5-week randomised, sham-controlled, double-blinded pilot clinical trial (n=72) is to assess the underlying mechanisms of action of iTBS in females in the late menopause transition and the relationship with cognition and mood. Data will be analysed using Stata^TM. Normality checks will guide the choice between parametric and non-parametric tests. Generalised linear models will assess within-subject and between-subject effects across timepoints, with additional regression analyses exploring associations between biomarkers, cognition and mood. Effect sizes, CIs and relevant test statistics will be reported, with significance set at p

The study protocol has been reviewed and ethically approved by the Western Sydney University Human Research Ethics Committee (H16200; 8 November 2024). All participants will provide written informed consent prior to enrolment. Results from this trial will be disseminated via peer-reviewed publications and conference presentations, with findings shared in accordance with open science and data transparency principles.
