Background: A randomized trial of unruptured brain arteriovenous malformations (ARUBA) reported superior outcomes in conservative management compared to interventional treatment. There were numerous limitations to the study. This study aimed to investigate the efficacy of gamma knife radiosurgery (GKS) for patients with brain arteriovenous malformations (AVMs) by comparing its outcomes to those of the ARUBA study.

Methods: We retrospectively reviewed ARUBA-eligible patients treated with GKS from June 2002 to September 2017 and compared against those in the ARUBA study. AVM obliteration and hemorrhage rates, and clinical outcomes following GKS were also evaluated.

Results: The ARUBA-eligible cohort comprised 264 patients. The Spetzler-Martin grade was Grade I to II in 52.7% and III to IV in 47.3% of the patients. The mean AVM nidus volume, marginal dose, and follow-up period were 4.8 cm³, 20.8 Gy, and 55.5 months, respectively. AVM obliteration was achieved in 62.1%. The annual hemorrhage rate after GKS was 3.4%. A stroke or death occurred in 14.0%. The overall stroke or death rate of the ARUBA-eligible cohort was significantly lower than that of the interventional arm of the ARUBA study ( < 0.001) and did not significantly differ from that of the medical arm in the ARUBA study ( = 0.601).

Conclusion: GKS was shown to achieve a favorable outcome with low procedure-related morbidity in majority of the ARUBA-eligible patients. The outcome after GKS in our patients was not inferior to that of medical care alone in the ARUBA study. It is suggested that GKS is rather superior to medical care considering the short follow-up duration of the ARUBA study.

Patient-reported outcome measures (PROMs) are crucial within person-centered care. The use of electronic PROMs (ePROMs) is increasing and multiple advantages have been described. The Patient and Observer Scar Assessment Scale (POSAS) is a validated paper questionnaire to assess patient-reported scar quality in the burn and scar population.

Objective: To build a supervised machine learning (ML) model that selects the best first-line treatment strategy for unruptured bAVMs.

Methods: A Randomized Trial of Unruptured Brain Arteriovenous Malformations (ARUBA) trial data was obtained from the National Institute of Neurological Disorders and Stroke (NINDS). A team of five clinicians examined the demographic, clinical, and radiological details of each patient at baseline and reached a consensus on the best first-line treatment for bAVMs.

Seeking consensus on physician leadership development in rural and remote Indonesian primary care settings: a Delphi study.

Leadersh Health Serv (Bradf Engl)

January 2025

Department of Educational Development and Research, Maastricht University, Maastricht, The Netherlands and Department of Pediatrics, Dr Horacio E Oduber Hospital, Oranjestad, Aruba.

Purpose: This study aims to formulate a consensus on primary care physicians' leadership competencies tailored to Indonesia's rural and remote health systems using the LEADS framework. Effective physician leaders are essential in these settings; however, many physicians lack the necessary leadership qualifications due to insufficient training. From a medical education perspective, this issue is further compounded by the lack of consensus on leadership course content.

Composition and distribution of the near-shore waters bordering the coral reefs of Aruba, Bonaire, and Curaçao in the Southern Caribbean.

This study aimed to identify ocean- and land-based sources of nutrients to the coral reef communities surrounding the Southern Caribbean islands Aruba, Bonaire, and Curaçao (ABC islands). The composition of water masses around these islands were assessed to depths up to 300 m and three distinct overlying water masses were identified, separated by mixing zones. A fluctuating pycnocline separating surface from deeper (>∼50 m) water indicated the presence of internal waves.

Article Synopsis
  • The study investigates the impact of non-culprit (NC) lesions in patients with NSTEMI compared to those with STEMI, focusing on high-risk plaque features and their influence on clinical outcomes.
  • Among 438 patients, both NSTEMI and STEMI groups showed similar prevalence of high-risk plaques, but NSTEMI patients had a higher rate of major adverse cardiovascular events (MACE) after two years.
  • The findings suggest that the presence of high-risk plaques in NC lesions is critical for dictating future cardiovascular events, indicating the need for further research on effective revascularization strategies in NSTEMI patients.
