Exposure therapy is a central component of the first-line treatment for anxiety disorders, a common mental health condition that is twice as prevalent in women relative to men. A key underlying mechanism of exposure therapy is fear extinction, which is an active learning process supported by a neural circuitry that is highly regulated by ovarian hormones. This review synthesises research examining the impact of hormonal contraceptives on laboratory fear extinction tasks in female rats and women, and on exposure therapy in women with anxiety disorders. The evidence indicates that hormonal contraceptives have a detrimental impact on fear extinction and exposure therapy that is consistent across species, and from laboratory to clinical settings. Candidate pathways by which hormonal contraceptives impede fear extinction and exposure therapy include suppression of endogenous ovarian hormones and glucocorticoids, and downregulation of signalling pathways that support extinction learning. Key areas of focus for future research are discussed.

Periodontal disease stands the leading cause of tooth loss in adults. While scaling and root planning is considered the "gold standard" treatment, it is often insufficient in efficiently eliminating anaerobic bacteria from deep periodontal pockets. In this work, an antibiotic-free and photo-curing hyaluronic acid-Janus (H-Janus) antibacterial pack was developed to inhibit the growth and colonization of residual bacteria within the pockets for reducing the recurrence of periodontitis.

Dentin hypersensitivity is primarily caused by the exposure of dentinal tubules due to various factors, so the key to treatment is to effectively seal these exposed tubules. However, traditional dentinal tubule sealants used in clinical practice often fail to adhere securely to the tubule surface when exposed to external stimuli, resulting in a recurrence of sensitivity. In this study, we developed a silicon micromotor that moved autonomously and loaded with silver nanoparticles and a photosensitive adhesive for dentin sensitivity therapy.

Pertussis is an important public health and clinical issue in China currently. Macrolide resistance in is a serious challenge to prevent and manage pertussis in China. Early, timely and effective antimicrobial therapy plays an important role in alleviating disease, reducing complications and severe diseases, eliminating carriers and reducing secondary transmission, and implementing post-exposure chemoprophylaxis in special scenarios is also necessary to protect individuals at high risk of severe diseases.

However, there is no comprehensive evidence synthesis and evaluation of the effectiveness of mental health interventions for adolescents living with HIV/AIDS in this region. We aim to conduct a systematic review to synthesise the literature on existing mental health interventions for adolescents living with HIV/AIDS in sub-Saharan Africa.

Introduction: Acute kidney injury (AKI) is common in hospitalised adults and children and is associated with significantly increased mortality and worse short-term and long-term outcomes. This systematic review and meta-analysis will evaluate the cost associated with AKI.
Methods And Analysis: This health economic analysis will be performed using systematic search of databases, including MEDLINE, EMBASE, CINAHL, Scopus and Cochrane Library from 2009 to the present (search completed on 27 May 2024).
