How Patients With Cancer Use the Internet to Search for Health Information: Scenario-Based Think-Aloud Study.

JMIR Infodemiology

January 2025

Amsterdam School of Communication Research/ASCoR, Department of Communication Science, University of Amsterdam, Amsterdam, Netherlands.

Background: Patients with cancer increasingly use the internet to seek health information. However, thus far, research treats web-based health information seeking (WHIS) behavior in a rather dichotomous manner (ie, approaching or avoiding) and fails to capture the dynamic nature and evolving motivations that patients experience when engaging in WHIS throughout their disease trajectory. Insights can be used to support effective patient-provider communication about WHIS and can lead to better designed web-based health platforms.

Patient-specific scaphoid prosthesis: surgical technique.

Arch Orthop Trauma Surg

December 2024

Biomedical Engineering and Physics, Amsterdam UMC Location University of Amsterdam, Meibergdreef 9, Amsterdam, The Netherlands.

The scaphoid bone is essential for wrist stability, force transmission, and movement, being crucial for maintaining carpal kinematics. In cases where the scaphoid is non-reconstructable, a complete replacement can serve as a treatment option to preserve carpal alignment and motion. This approach has evolved since its first descriptions in 1945, benefiting significantly from advancements in patient-specific implant design, additive manufacturing/3D printing, and material use in recent years.

Since the early 2000s, malaria cases in Cambodia have declined steadily. Village malaria workers (VMWs) have played a critical role in reducing malaria transmission and progress towards malaria elimination. To prevent malaria re-establishment, however, implementation strategies need to consider carefully the changing healthcare needs in the communities as well as challenges to, and opportunities for, programme adaptation.

Background: Lithopaedion, or "stone baby," represents an exceptionally rare clinical phenomenon with fewer than 350 documented cases existing in the medical literature. This condition arises when an advanced extrauterine pregnancy ceases its developmental trajectory and undergoes a lithification process, potentially resulting in a calcified mass with fetal-like morphology. Typically, lithopaedions remain asymptomatic for decades, but may occasionally elicit acute symptoms necessitating medical intervention.

Article Synopsis
  • Synovial sarcoma (SS) is a rare type of cancer, primarily found in genitourinary tissues, commonly linked to the SS18::SSX gene fusion, and its paratesticular occurrence is extremely uncommon, with only 4 documented cases prior to this study.
  • This research details the characteristics and genetic profile of the largest cohort of paratesticular SS patients, analyzing data from 14 individuals aged 15 to 47, all of whom underwent surgical removal of the tumors and some received chemotherapy.
  • The findings indicate a generally poor prognosis for paratesticular SS even after aggressive treatment, emphasizing the need for thorough diagnostic methods to differentiate it from similar conditions, and supporting the use of SS18-SS

Reliable predictors for electroconvulsive therapy (ECT) effectiveness would allow a more precise and personalized approach for the treatment of major depressive disorder (MDD). Prediction models were created using a priori selected clinical variables based on previous meta-analyses. Multivariable linear regression analysis was used, applying backwards selection to determine predictor variables while allowing non-linear relations, to develop a prediction model for depression outcome post-ECT (and logistic regression for remission and response as secondary outcome measures).

Recently, a GuMI gut microphysiological system has been established to coculture oxygen-intolerant () A2-165 with organoids-derived primary human colonic epithelium. This study aims to test if this GuMI system applies to different donors with different healthy states and uses metabolomics to reveal the role of gut microbes in modulating host- and diet-derived molecules in the gut lumen. Organoids-derived colonic monolayers were generated from an uninflamed region of diverticulitis, ulcerative colitis, and Crohn's disease patients and then integrated into the GuMI system to coculture with A2-165 for 2 to 4 days.
