Barriers and missed opportunities in PrEP uptake, use and care among men who have sex with men with recent HIV infection in the Netherlands.

Introduction: Oral pre-exposure prophylaxis (PrEP) prevents Human Immunodeficiency Virus (HIV) acquisition. In the Netherlands, PrEP is accessible through the national PrEP program (NPP) or general practitioners (GP). Still, some men who have sex with men (MSM) entering HIV care indicated having PrEP experience prior to diagnosis.

What determines mpox vaccination uptake? Assessing the effect of intent-to-vaccinate versus other determinants among men who have sex with men.

Background: In response to the mpox outbreak, vaccination was offered in the Netherlands to men who have sex with men (MSM) at increased risk for mpox. Successful vaccination campaigns are leveraged by high intent-to-vaccinate, yet intent might not always lead to uptake. Therefore, we assessed the impact of intent-to-vaccinate and other factors on vaccination uptake among participants of the Amsterdam Cohort Studies (ACS).

High Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Household Transmission Rates Detected by Dense Saliva Sampling.

Background: Understanding the dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) household transmission is important for adequate infection control measures in this ongoing pandemic.

Methods: Households were enrolled upon a polymerase chain reaction-confirmed index case between October and December 2020, prior to the coronavirus disease 2019 vaccination program. Saliva samples were obtained by self-sampling at days 1, 3, 5, 7, 10, 14, 21, 28, 35, and 42 from study inclusion.

Diet and Anthropometrics of Children With Inflammatory Bowel Disease: A Comparison With the General Population.

Background: There is a lack of knowledge regarding the diet of children with inflammatory bowel disease (IBD). Therefore, we investigated dietary intake in pediatric IBD compared to the general population and assessed anthropometrics and food avoidance.

Methods: In this cross-sectional cohort study, patients younger than 18 years with IBD were included (2014-2017).

Giant aneurysms: A gender-specific complication of Kawasaki disease?

Background: Kawasaki disease (KD) is a pediatric vasculitis of unknown origin. Its main complication is the development of coronary artery aneurysms (CAA) with giant CAA at the end of the spectrum.

Methods: In this cohort study, we evaluated the association between patient characteristics and the development of giant CAA based on z-scores.
