Surfaces consisting of sub micron holes (0.420-0.765 μm) engineered into nanoparticle (12 nm) coatings were examined for marine antifouling behaviour that defines early stage settlement. Immersed surfaces were found to be resistant to a 5-hour attachment assay of Amphora coffeaeformis, a marine organism commonly found in abundance on fouled substrates such as foul-releasing paints and self-polishing coatings. Attachment inhibition was attributed to the accessibility of diatoms to the surface. This was governed by the size and morphology of trapped interfacial air pockets measured in-situ using synchrotron small angle x-ray scattering. Surfaces containing larger pores (0.765 μm) exhibited the highest resistance. Macroscopic wettability via contact angle measurements however remained at 160° and sliding angle of < 5° and was found to be independent of pore size and not indicative of early stage fouling behaviour. The balance of hierarchical nano/micro length scales was critical in defining the early stage stability of biofouling character of the interface.

Background: The high and increasing rate of poor mental health among young people is a matter of global concern. Experiencing poor mental health during this formative stage of life can adversely impact interpersonal relationships, academic and professional performance, and future health and well-being if not addressed early. However, only a few of those in need seek help.

Auricular reconstruction is essential for restoring facial symmetry and achieving a well-contoured, natural-appearing ear. Traditional methods using autologous costal cartilage often delay reconstruction until around age 10, when sufficient rib cartilage is available, which can pose physical and psychological challenges for pediatric patients. Porous high-density polyethylene (PHDPE) implants offer significant advantages, including the ability to perform reconstruction earlier, reduced morbidity, improved ear definition, and the possibility of a single-stage outpatient procedure.

Study Question: Does weight loss from a hypocaloric dietary intervention improve antral follicle dynamics in women with PCOS?
Summary Answer: During a 3-month hypocaloric dietary intervention, women with PCOS who experienced clinically meaningful weight loss showed more organized antral follicle development including fewer recruitment events, but no change in the overall frequency of selection, dominance, or ovulation.
What Is Known Already: There is a spectrum of disordered antral follicle development in women with PCOS including excessive follicle recruitment and turnover, decreased frequency of selection and dominance, and failure of ovulation. Lifestyle intervention aimed at weight loss is recommended to improve metabolic health in women with PCOS yet benefits on ovarian follicle development and ovulation are unclear.

Background: Prior studies have implicated diabetes as a risk factor for pancreatic cancer, yet the impact of diabetes progression on pancreatic cancer incidence remains unclear. We aim to assess pancreatic cancer risk across different stages of diabetes.
Methods: Employing a predefined search strategy, we conducted a literature review of electronic databases up to 29 February 2024.
