    Abstract Heather (Calluna vulgaris), a common dietary component of many mammalian herbivores, contains a broad range of tannin phenolics, flavonoids, and simple phenolic compounds. These may lead to a number of negative effects on herbivores as a result of toxicity or digestive inhibition. We assessed the effect of some simple phenolic compounds from heather on rumen microbial activity using thein vitro consecutive batch culture technique. The compounds tested were orcinol, quinol, and arbutin, a glucoside of quinol. At a concentration of 10 mM, both orcinol and quinol depressed production of gas and volatile fatty acids (VFAs). Orcinol and, to a lesser extent, quinol also reduced digestion of the substrate. In contrast to these negative effects on rumen microbial fermentation, arbutin stimulated both gas and VFA production, probably due to the presence of the fermentable sugar moiety. The presence of arbutin also resulted in different concentrations and proportions of VFAs compared to the presence of orcinol and quinol. Since many simple phenolic compounds are found in plants in the form of glycosides, the negative digestive effects of the phenolic moieties may be accompanied by the positive effect of the sugar moiety, which is liberated in the gastrointestinal tract on hydrolysis by glycosidase enzymes. This study suggests that when phenolics are present as glycosides, they do not necessarily adversely affect digestion by herbivores.

    Series title Bioethics for social justice
    Abstract Microaggressions in Medicine introduces a novel account of microaggressions and applies it in medical contexts. Guided by diverse patient testimonies and case studies, it focuses on harms experienced by patients marginalized on the basis of race, gender, sexual orientation, body size, and disability. It makes a compelling case that the harms of microaggressions are anything but micro and argues that healthcare professionals have a moral obligation to prevent them. By proving practical strategies for healthcare professionals to reduce microaggressions in their practices, Microaggressions in Medicine will make a positive difference in the lives of marginalized patients as they interact with healthcare professionals. All patients deserve high quality, patient-centered care, but healthcare professionals must change their practices in order to achieve such equity.

    Abstract Spontaneous lower extremity arterial dissection has been linked to atherosclerotic and non-atherosclerotic causes. A 55-year-old male presented to the emergency department via emergency medical services for a chief complaint of right leg pain. He stated that he was performing leg exercises when he felt a sudden pop in his right leg followed by severe pain. His exam was remarkable for lack of ipsilateral distal popliteal or dorsalis pedis pulse by palpation or doppler. The patient was admitted to a three-year history of non-prescription testosterone injection use along with a history of prior portal vein thrombosis two years prior with anticoagulation noncompliance after one month of therapy. A computed tomography angiography of the lower extremity was performed which demonstrated complete acute occlusion of the right common iliac, and right external iliac, along with right femoral artery dissection. The patient was emergently taken to the operating room with vascular surgery where a thrombectomy with stent placement was performed. After three days in the surgical intensive care unit and nine days in the hospital, the patient was subsequently discharged from the hospital in good condition. A post-operative follow-up appointment three weeks after discharge revealed mild residual pain; however, no issues ambulating or residual weakness, and normal ankle-brachial indexes. This case highlights a unique presentation of acute limb ischemia associated with exogenous testosterone use.

    Abstract Artificial intelligence is already all around us, and its usage will only increase. Knowing its capabilities is critical. A facial recognition system (FRS) is a tool for law enforcement during suspect searches and when presenting photos to eyewitnesses for identification. However, there are no comparisons between eyewitness and FRS accuracy using video, so it is unknown whether FRS face matches are more accurate than eyewitness memory when identifying a perpetrator. Ours is the first application of artificial intelligence to an eyewitness experience, using a comparative psychology approach. As a first step to test system accuracy relative to eyewitness accuracy, participants and an open-source FRS (FaceNet) attempted perpetrator identification/match from lineup photos (target-present, target-absent) after exposure to real crime videos with varied clarity and perpetrator race. FRS used video probe images of each perpetrator to achieve similarity ratings for each corresponding lineup member. Using receiver operating characteristic analysis to measure discriminability, FRS performance was superior to eyewitness performance, regardless of video clarity or perpetrator race. Video clarity impacted participant performance, with the unclear videos yielding lower performance than the clear videos. Using confidence-accuracy characteristic analysis to measure reliability (i.e., the likelihood the identified suspect is the actual perpetrator), when the FRS identified faces with the highest similarity values, they were accurate. The results suggest FaceNet, or similarly performing systems, may supplement eyewitness memory for suspect searches and subsequent lineup construction and knowing the system's strengths and weaknesses is critical.

    Abstract Objectives: The American Academy of Pediatrics strongly recommends that children age 2 and under should have little to no digital media exposure. However, most children are exposed to regular screen time at home. This may also be true for hospitalized children. Through education and access to alternatives, we aimed to reduce screen exposure in our children's hospital for children 2 and under.
    Methods: Between January 2020 and May 2021, we designed and implemented a quality improvement intervention to educate staff and caregivers on the American Academy of Pediatrics screen time recommendations and offer alternatives for hospitalized children. Our primary aim was to decrease screen time exposure for children age 2 and under by 50% within 12 months of project initiation. Balancing measures included staff perception of workload when using screens and perceived parental acceptance of screens being turned off.
    Results: During baseline data collection period, screens were on for an average of 63% of the audits. Following interventions, the average was reduced to 40%. The outcome measure met special cause with 8 consecutive points below the center line. There was a significant increase in staff who reported offering screen alternatives after intervention. Staff perception of workload and perceived parental acceptance was unchanged.
    Conclusions: Through implementation of this quality improvement initiative, we reduced screen time by approximately 37% without impacting staff workload. Most importantly, we were able to educate staff and model best practices for caregivers, which may carry into the home, leading to a reduction of screen time and improved health overall.

    Abstract Introduction: It is estimated that approximately 30% to 70% of international travellers will develop diarrhoea during their travels or after returning home.
    Methods and outcomes: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute mild-to-moderate diarrhoea in adults from resource-rich countries travelling to resource-poor countries? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
    Results: We found 24 studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
    Conclusions: In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (empirical), antibiotics plus antimotility agents, antimotility agents, bismuth subsalicylate, diet, oral rehydration solutions, and racecadotril for travellers' diarrhoea.
