Abstract

BackgroundThe irrational use of antibiotics in poultry production has far-reaching consequences and continues to impact the fight against antimicrobial resistance (AMR) in Africa. In Nigeria, antibiotics are available over-the-counter and are widely used in food animal production for various reasons, including prophylaxis and growth promotion. While this practice may support animal production, it also drives the spread of AMR, posing serious health challenges due to close human-livestock interactions and the countrys high disease burden. This study examined poultry farmers knowledge, attitudes, and practices (KAP) regarding antibiotic use and AMR, aiming to highlight the public health risks and challenges in combating AMR in Nigeria. MethodsA cross-sectional survey of 200 poultry farms in Enugu State, Southeast Nigeria, was conducted to evaluate farmers KAP towards antibiotic usage and AMR. Using a validated, standardized, and self-administered questionnaire, data were collected from farmers responsible for key farm decisions, including input and feed management. The questionnaire comprised three sections: socio-demographic data, knowledge of AMR, and knowledge and practices regarding antibiotic use. Ethical approval was obtained, and participants gave oral consent based on their professional capacity. ResultsThe evaluation of poultrys farmers KAP regarding antibiotic usage and AMR revealed that the majority of farmers (90.5%) reported using antibiotics, primarily for treating infections (80.5%) or for feed enhancement, growth promotion, and prophylaxis (61%). Ampicillin (75%), ciprofloxacin (71.5%), and doxycycline (71%) were the most commonly administered antibiotics. Monthly administration was the most common (48%), and 89% of respondents believed that antibiotics promote poultry growth. Interestingly, a substantial proportion of respondents (65%) were unaware of AMR, highlighting a significant knowledge gap, with only 16% recognizing the risk of AMR infections. ConclusionOur study revealed that the surveyed poultry farmers heavily rely on antibiotics, primarily for treating infections and, to a significant extent, for growth promotion, despite their limited awareness of AMR. Ampicillin was identified as the most commonly used antibiotic, raising concerns due to its potential link to beta-lactamase selection amid the countrys carbapenem resistance issues. These findings underscore the urgent need for targeted education to address the AMR knowledge gap and reduce the misuse of antibiotics in poultry farming settings in Nigeria.

Auditing Biomedical Literature with Blinded AI Peer Review: Where Peer Review Works, Where It Fails, and How to Strengthen It

Biomedical publishing has grown more than elevenfold since 1991, outstripping human peer review. Unblinded language models cannot audit this literature objectively because they recognize famous authors and journals from training memory. We built BARS (Blinded AI Review System), an automated referee that strips titles, author names, institutions, journal headers, and dates before grading full-text manuscripts on a 10-point scale covering methods, evidence, biology, and reproducibility. We used BARS to generate 1,874 blind reviews across 1,714 unique papers. BARS passed 100% of verified sound controls, caught 77% to 91% of internally flawed papers, eliminated a +0.35-point prestige boost, and more than doubled human referee consistency. Across 320 recent open-access articles (2020-2025) from eight fields, 54% failed on core scientific rigor (<5.0/10; 41% excluding megajournals). Revision at selective journals improved preprints more than twice as much as revision at commercial megajournals (+0.62 vs. +0.30 points; baseline-adjusted p = 0.033), and BARS recalled 98% of unresolved human referee critiques across 100 open-review papers. Across 915 date-blinded papers from 1991 to 2025, average scores fell from 7.6/10 to 5.8/10 as megajournals and template database studies expanded. Blinded self-audits of 238 papers by two senior authors -- and of this manuscript itself -- caught real statistical, control, and table errors in our own work. At four cents per paper, BARS offers a practical quality check for authors, journals, and readers (https://veg.github.io/BARS/).

From Problems to Solutions: How Self-Questions Drive Strong Scientific Reasoning

Metacognition, or awareness and control of thinking, is essential for problem solving because it helps solvers select strategies for learning and decide when to enact them (planning), check their understanding in the moment (monitoring), and assess effectiveness of solutions and learning strategies (evaluating). Most studies that examine metacognition do so retrospectively, leaving a critical gap in how metacognition is used in-the-moment for problem solving. In this study, we utilized a think-aloud interview approach to capture and characterize the metacognitive skills that senior undergraduate life science students at three institution types in the United States used spontaneously while solving challenging biology problems. We found that the students (n = 39) displayed a wide variety and quantity of monitoring, some evaluating, and nearly no planning skills while creating a solution backed with high-quality reasoning. Students frequently used self-questions to monitor and evaluate their thinking. We found that self-questioning is a critical skill for generating solutions, but it only moves problem solving forward if the student asks and correctly answers the self-question out loud. This study illustrates how self-questioning and other metacognitive regulation skills provide links to bridge the gap between a student's prior knowledge and specific features of a challenging problem. Based on our student data, we conceptualized a model of metacognitive phases during problem solving with high-quality reasoning. Finally, we present a self-question scaffold to facilitate the proposed phases (planning, monitoring, reasoning, and evaluating) so educators can equip students with metacognitive and scientific reasoning tools for effective problem solving.

Preprint solicitation as a natural experiment in scholarly publishing

Preprinting is a growing and increasingly recognized mechanism for scientific communication and productivity and a way to facilitate global access to science. The interplay of preprinting practices with formal peer-reviewed publication is an open question that is now tractable to targeted analysis. Here, we take advantage of nearly a decade of preprint solicitation at Proceedings B to address this question, which offers a quasi-experimental setting for comparing outcomes for solicited preprints and traditionally submitted manuscripts. We used submission records from 15,368 manuscripts from 2018-2024 to assess whether preprint solicitation affects acceptance rates, journal scope, author geographic diversity, and post-publication uptake. Solicited manuscripts were accepted at nearly twice the rate of traditional submissions and received more downloads and citations after publication. Submission topics were broadly similar between the two routes, though solicited manuscripts showed marginally greater subject diversity. Geographic disparities favoring the Global North persisted, but acceptance rates for solicited manuscripts converged across regions, narrowing the gap seen in traditional submissions. These findings extend earlier work on this initiative and indicate that editor-driven solicitation can identify high-quality preprints, broaden geographic representation, and increase research visibility, offering a replicable model for journals seeking to diversify authorship while maintaining editorial standards.
