Background: According to current guidelines, atovaquone/proguanil (AP) malaria chemoprophylaxis is taken once daily during travel, and continued for seven days after return from malaria-endemic areas. However, pharmacokinetic data and studies on drug-sparing AP regimens suggest that AP could possibly be discontinued upon return without loss of protection. Besides being more cost-effective, shorter AP regimens may enhance adherence. We aimed to investigate adherence to the current AP chemoprophylaxis regimen during the seven days post-travel, and travellers' preferences for potential drug-sparing AP regimens., Methods: In this cross-sectional study, adult travellers, who were prescribed AP chemoprophylaxis during a pre-travel consultation between 01-12-2022, and 01-12-2023 at the Amsterdam UMC travel clinic, were send a post-travel online questionnaire. The primary outcome was the proportion of travellers non-adherent to AP during the seven days post-travel, defined as missing one tablet or more. Secondary outcomes were non-adherence during travel, reasons for non-adherence, and AP regimen preferences., Results: The questionnaire was completed by 62% (382/614) of contacted travellers. Of the participants, 31% (117/382) reported non-adherence during the seven days post-travel; during stay this was 16% (58/382). Frequently reported reasons for non-adherence were: forgetfulness, low self-perceived malaria risk, and adverse effects. An alternative AP regimen discontinuing AP upon return was deemed most appealing and easy to adhere by 73% (276/376) of participants., Conclusions: Non-adherence was high during the seven days after return. Travellers preferred an alternative AP chemoprophylaxis regimen, allowing them to discontinue upon return. Future research shall be conducted to investigate whether AP could be discontinued upon return., Competing Interests: Declaration of Competing Interest ☒ The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025.

Background . Artificial intelligence (AI) is an era upcoming in medicine and, more recently, in the operating room (OR). Existing literature elaborates mainly on the future possibilities and expectations for AI in surgery. The aim of this study is to systematically provide an overview of the current actual AI applications used to support processes inside the OR. Methods . PubMed, Embase, Cochrane Library, and IEEE Xplore were searched using inclusion criteria for relevant articles up to August 25th, 2020. No study types were excluded beforehand. Articles describing current AI applications for surgical purposes inside the OR were reviewed. Results . Nine studies were included. An overview of the researched and described applications of AI in the OR is provided, including procedure duration prediction, gesture recognition, intraoperative cancer detection, intraoperative video analysis, workflow recognition, an endoscopic guidance system, knot-tying, and automatic registration and tracking of the bone in orthopedic surgery. These technologies are compared to their, often non-AI, baseline alternatives. Conclusions . Currently described applications of AI in the OR are limited to date. They may, however, have a promising future in improving surgical precision, reduce manpower, support intraoperative decision-making, and increase surgical safety. Nonetheless, the application and implementation of AI inside the OR still has several challenges to overcome. Clear regulatory, organizational, and clinical conditions are imperative for AI to redeem its promise. Future research on use of AI in the OR should therefore focus on clinical validation of AI applications, the legal and ethical considerations, and on evaluation of implementation trajectory.
