Background: Cognitive impairment after anaesthesia and surgery is a recognised consequence. This often leads to poor health outcomes and increases healthcare resource utilisation and associated costs, especially in elderly people. However, thus far, there have not been any effective therapies for managing postoperative cognitive dysfunction (POCD). Furthermore, research on the association of multimodal warming with POCD and the clinical outcomes in older patients after gynaecological surgery has not been rigorous. For these reasons, our investigation aims to evaluate whether perioperative multimodal warming would reduce the incidence of POCD and improve prognosis in elderly patients with gynaecological cancer.
Methods And Analysis: This is a single-centre, prospective, single-blinded randomised controlled trial. One hundred and fifty patients for gynaecological cancer surgery and 16 non-surgical controls aged 65 years or older will be studied in this trial. A series of neuropsychological tests will be completed to evaluate cognitive function in surgery patients before, at day 7 and 3 months after gynaecological cancer surgery. In addition, POCD and cognitive decline will be assessed using the reliable change index using the control group's results. The primary outcome is the prevalence of POCD in elderly gynaecological cancer surgery patients and association between perioperative multimodal warming and POCD.
Ethics And Dissemination: The protocol for this prospective observational study was approved by the ethics committee of the West China Second University Hospital, Sichuan University (NO. KX215). Recruitment will commence in April 2021 and continue to April 2022. The findings of this trial will be disseminated in peer-reviewed journals and scientific meetings.

Purpose: In humans, 2-deoxy-2-[F]fluoro-D-glucose ([F]FDG) tumour-to-background contrast continues to increase long after a typical uptake period of 45 - 60 min. Similar studies have not been performed in mice and the static imaging time point for most studies is arbitrarily set at 30 - 60 min post-injection of [F]FDG. Ideally, static PET imaging should be performed after the initial period of rapid uptake but this period has not been defined in mice, with previous dynamic studies in mice being limited to 60 min.

Article Synopsis
- Maintaining normothermia during surgery is essential to prevent complications like infections and adverse cardiovascular events; the study explores combining Western medicine with traditional Chinese medicine (TCM) for better temperature management.
- A thorough literature review examines the causes and management of perioperative hypothermia, assessing various techniques from both medical perspectives, including their effectiveness and potential complications.
- The study concludes that integrating Western and TCM approaches can improve patient outcomes and reduce the risk of inadvertent perioperative hypothermia (IPH), enhancing overall safety and recovery.
The co-benefits of climate change mitigation strategies on cardiovascular health: a systematic review.
Lancet Reg Health West Pac

Faculty of Medicine and Health Sciences, Macquarie University, Sydney, NSW, Australia.
Article Synopsis
- Climate change poses a serious risk to global health, with 62% of climate-related deaths linked to cardiovascular disease (CVD), mainly due to global warming and pollution.
- A systematic review analyzed various climate mitigation strategies from 2012 to 2022, linking them to the reduction of CVD morbidity and mortality.
- The findings suggest that strategies like renewable energy, active transport, green spaces, and plant-based diets not only address climate change but also significantly benefit cardiovascular health.
Promoting behavioural change by educating anaesthetists about the environmental impact of inhalational anaesthetic agents: A systematic review.
Anaesth Intensive Care

Discipline of Health Professions Education, The University of Western Australia, Crawley, Australia.
Of the total carbon footprint of Australia, 7% is attributed to healthcare. In the UK, inhalational agents make up 5% of the healthcare carbon footprint. This systematic review aims to determine which methods of education about the environmental impact of inhalational anaesthetic agents can be utilised to promote behaviour change, reducing the anaesthetic-related carbon footprint.

IEEE Trans Image Process
September 2024
The rise of the metaverse and the increasing volume of heterogeneous 2D and 3D data have created a growing demand for cross-modal retrieval, enabling users to query semantically relevant data across different modalities. Existing methods heavily rely on class labels to bridge semantic correlations; however, collecting large-scale, well-labeled data is expensive and often impractical, making unsupervised learning more attractive and feasible. Nonetheless, unsupervised cross-modal learning faces challenges in bridging semantic correlations due to the lack of label information, leading to unreliable discrimination.
