The European Journal of Endocrinology recently published a paper (Asscheman et al.) presenting mortality data from more than a thousand transsexuals followed for a median time of 18 years and who had undergone previous or were currently on long term cross-sex hormonal treatment. Transsexualism is a rare condition and in scientific literature there are few reports on the long-term safety of different treatment protocols and on the physical and psychological outcomes of medical treatments. The safety of long-term high doses oestrogen or testosterone in subjects of the opposite sex has been debated and data on long term effects are scant at best. The Asscherman paper therefore represents a very important and reassuring reference for professionals working in this field suggesting that mortality is increased among transsexuals although due to causes unrelated to cross sex replacement therapy. These results will benefit the care and treatment of these subjects.

Two-dimensional Transition Metal Dichalcogenides (2D TMDs) have garnered significant attention in the field of materials science due to their remarkable electronic and optoelectronic properties, including high carrier mobility and tunable band gaps. Despite the extensive research on various TMDs, there remains a notable gap in understanding the synthesis techniques and their implications for the practical application of monolayer tungsten disulfide (WS2) in optoelectronic devices. This gap is critical, as the successful integration of WS2 into commercial technologies hinges on the development of reliable synthesis methods that ensure high quality and uniformity of the material.

Background: Despite the increasing popularity of electronic devices, the longitudinal effects of daily prolonged electronic device usage on brain health and the aging process remain unclear.
Objective: The aim of this study was to investigate the impact of the daily use of mobile phones/computers on the brain structure and the risk of neurodegenerative diseases.
Methods: We used data from the UK Biobank, a longitudinal population-based cohort study, to analyze the impact of mobile phone use duration, weekly usage time, and playing computer games on the future brain structure and the future risk of various neurodegenerative diseases, including all-cause dementia (ACD), Alzheimer disease (AD), vascular dementia (VD), all-cause parkinsonism (ACP), and Parkinson disease (PD).

Background: Skin cancers, including melanoma and keratinocyte cancers, are among the most common cancers worldwide, and their incidence is rising in most populations. Earlier detection of skin cancer leads to better outcomes for patients. Artificial intelligence (AI) technologies have been applied to skin cancer diagnosis, but many technologies lack clinical evidence and/or the appropriate regulatory approvals.

Background: Prompts offer a promising strategy to promote client engagement in internet-delivered cognitive behavioral therapy (ICBT). However, if the prompts do not meet the needs of clients, they can potentially be more obtrusive rather than helpful.
Objective: The aim of this study was to test if prompts tailored based on timing and frequency, aligned with preintervention goal setting, can increase usage and the efficacy of a therapist-supported ICBT stress recovery intervention for health care workers.

Background: One-stage direct-to-implant (DTI) breast reconstruction is increasingly popular with the use of prepectoral reconstruction leading to increased demand for structural scaffolds. It is vital to determine if differences in safety profiles exist among scaffolds.
Methods: We performed a retrospective cohort study of consecutive patients in our breast cancer center undergoing DTI reconstruction.
