Article Synopsis
  • - The experiment at Lawrence Berkeley National Laboratory aimed to produce a superheavy element with an atomic number of 114 or greater by bombarding an actinide target with a ^{50}Ti beam.
  • - Using the Berkeley Gas-filled Separator, researchers successfully isolated and implanted produced Livermorium (Lv) ions into a high-tech detector system, observing two decay chains linked to ^{290}Lv.
  • - The measured production cross-section of the process was 0.44 picobarns at a specific energy, marking the first published evidence of superheavy element production near the "island of stability" with this method, paving the way for future discoveries beyond element Z=118.

Background: Patients with moderate-to-severe atopic dermatitis (AD) experience skin lesions and intense itch that substantially affect quality of life. Patients have choices among systemic AD treatments that offer varied benefit-risk profiles.

Objective: Measure patients' willingness to trade off the risks and benefits of systemic treatments among individuals with a physician-confirmed diagnosis of moderate-to-severe AD.

Background: Adolescents with attention-deficit/hyperactivity disorder (ADHD) experience aspects of their lives in diverse ways. They often have more energy and creativity which are positive traits of ADHD, while their inability to control their actions in academic or social spheres may cause feelings of inadequacy.

Aim: To explore illness-perception, including emotional experiences, in adolescent ADHD.

Background: Using traditional health technology assessment (HTA) outcome metrics, such as quality-adjusted life-years, to assess fertility treatments raises considerable methodological challenges because the objective of fertility treatments is to create new life rather than extend, save, or improve health-related quality of life.

Objective: The aim of this study was to develop a novel cost-benefit framework to assess value for money of publicly funded IVF treatment; to determine the number of cost-beneficial treatment cycles for women of different ages; and to perform an incremental cost-benefit analysis from a taxpayer perspective.

Methods: We developed a Markov model to determine the net monetary benefit (NMB) of IVF treatment by female age and number of cycles performed.

Background: Physicians' preferences for attributes of medical treatments for endometriosis-associated pain have not previously been quantified.

Methods: US obstetrician-gynecologists completed an online discrete-choice experiment survey. In a series of questions, physicians chose a medical treatment for a hypothetical patient with endometriosis experiencing severe, persistent dysmenorrhea, nonmenstrual pelvic pain, and/or dyspareunia.
