Purpose: This study focused on reducing the margin for prostate cancer treatment using magnetic resonance imaging-guided radiotherapy by investigating the intrafractional motion of the prostate and different motion-mitigation strategies.
Methods: We retrospectively analyzed intrafractional prostate motion in 77 patients with low- to intermediate-risk prostate cancer treated with five fractions of 7.25 Gy on a 1.
Article Synopsis
- * A study involving 4,488 young women assessed the vaccine's effectiveness against specific HPV types, finding high efficacy rates of 93.5% for HPV-16 and 89.5% for HPV-18, with additional cross-protection against other types.
- * Results showed that the vaccine's effectiveness was similar for women who participated in catch-up vaccinations compared to those who received routine vaccinations, indicating both approaches are equally effective.
Article Synopsis
- From 2009 to 2021, the Netherlands only offered bivalent HPV vaccination to girls, prompting an investigation into its effects on genital HPV prevalence among young adults.
- Data were collected through a study called PASSYON, which involved sexual health clinic clients aged 16-24, revealing significant declines in certain high-risk HPV types amongst vaccinated and unvaccinated females over time.
- The study highlighted successful herd protection effects of the vaccination for heterosexual males and unvaccinated females, while also indicating concerning trends of increasing HPV types related to vaccine phylogeny, suggesting potential type-replacement issues.
Nitrogen (N) is the most important nutrient in coffee, with a direct impact on productivity, quality, and sustainability. N uptake by the roots is dominated by ammonium (NH) and nitrates (NO), along with some organic forms at a lower proportion. From the perspective of mineral fertilizer, the most common N sources are urea, ammonium (AM), ammonium nitrates (AN), and nitrates; an appropriate understanding of the right balance between N forms in coffee nutrition would contribute to more sustainable coffee production through the better N management of this important crop.

Methods: Seropositivity and anal and penile HPV DNA-positivity were determined for seven high-risk HPV genotypes for MSM aged 16-24 years participating in Papillomavirus Surveillance among STI clinic Youngsters in the Netherlands (PASSYON) 2009-2021. Logistic regression models were conducted to assess risk factors for seropositivity, anal and penile HPV DNA-positivity.
