Article Synopsis
- Atomic Layer Etching (ALE) is crucial for creating complex 3D structures in integrated circuits, and new processes need to be explored to adapt ALE for various materials.
- A novel isotropic plasma ALE process using hexafluoroacetylacetone (Hhfac) combined with H plasma has been developed, achieving precise control of AlO film thickness with a stable etch rate of 0.16 nm per cycle and a high ALE synergy of 98%.
- Advanced techniques like Fourier transform infrared spectroscopy (FTIR) and density functional theory (DFT) simulations reveal that the ALE mechanism involves a balance between etching and surface inhibition reactions, allowing effective thickness control on a nanometer scale with minimal contamination.
Early Detection of Psychosis in Eating Disorders: Unnecessary or a Useful Addition?
Early Interv Psychiatry
November 2024
Article Synopsis
- The study aims to address the confusion surrounding symptoms that may indicate either a psychosis spectrum disorder or an eating disorder (ED), highlighting the need for better cooperation in treatment programs for early detection of both issues.* -
- Using a cross-sectional approach, researchers assessed a sample of outpatients aged 16-35 through various screening tools to identify individuals at risk for either condition, revealing that over half showed signs of an eating disorder and nearly 28.3% had at-risk mental states for psychosis.* -
- The findings suggest a significant overlap between psychotic symptoms and eating disorder traits, underlining the importance of integrated treatment approaches and encouraging further research into the connections between psychosis and ED symptoms.*

Article Synopsis
- ECMO (Extracorporeal Membrane Oxygenation) has high complication rates, prompting the need for improved management strategies, which led to the development of the REMAP ECMO platform to investigate effective patient management techniques.* -
- The REMAP ECMO platform allows for multiple adaptive randomized controlled trials, with the first focusing on the effects of early left ventricular unloading via intra-aortic balloon pumping compared to ECMO alone for cardiogenic shock patients in the ICU.* -
- The primary outcome aims to determine successful weaning from ECMO at 30 days, while secondary outcomes include intervention needs, survival rates, and quality of life, all analyzed using a flexible Bayesian statistical framework.*
Article Synopsis
- Sleep is essential for mental and physical health, and its disturbances are linked to psychiatric disorders, particularly in anorexia nervosa (AN), where the connection is not well understood.
- A systematic review analyzed 67 studies on sleep in patients with AN, revealing significant differences in sleep patterns compared to healthy controls, such as reduced total sleep time and efficiency, increased wake after sleep onset, and altered sleep stages.
- The findings indicate that sleep issues in AN are significant, and simply restoring weight may not improve sleep quality, highlighting the need for treatment strategies that address these sleep disturbances.
Study Question: Does offering the Pleasure&Pregnancy (P&P) programme rather than expectant management improve naturally conceived ongoing pregnancy rates in couples diagnosed with unexplained infertility?
Summary Answer: The P&P programme had no effect on the ongoing pregnancy rates of couples with unexplained infertility.
What Is Known Already: Underpowered studies suggested that face-to-face interventions targeting sexual health may increase pregnancy rates. The impact of an eHealth sexual health programme had yet to be evaluated by a large randomized controlled trial.
