Simple Summary Computerized tracking systems for primates and other animals are one of the great inventions of the 21st century. These systems have already revolutionized the study of primatology, psychology, neuroscience, and biomedicine. Less discussed is that they also promise to greatly enhance animal welfare. Their potential benefits include identifying and reducing pain, suffering, and distress in captive populations, improving laboratory animal welfare, and applying our understanding of animal behavior to increase the “natural” behaviors in captive and wild populations, especially those under threat. We are optimistic that these changes will greatly increase the welfare of primates, including those in laboratories, zoos, primate centers, and in the wild. Abstract Recent years have witnessed major advances in the ability of computerized systems to track the positions of animals as they move through large and unconstrained environments. These systems have so far been a great boon in the fields of primatology, psychology, neuroscience, and biomedicine. Here, we discuss the promise of these technologies for animal welfare. Their potential benefits include identifying and reducing pain, suffering, and distress in captive populations, improving laboratory animal welfare within the context of the three Rs of animal research (reduction, refinement, and replacement), and applying our understanding of animal behavior to increase the “natural” behaviors in captive and wild populations facing human impact challenges. We note that these benefits are often incidental to the designed purpose of these tracking systems, a reflection of the fact that animal welfare is not inimical to research progress, but instead, that the aligned interests between basic research and welfare hold great promise for improvements to animal well-being.

The Promise of Behavioral Tracking Systems for Advancing Primate Animal Welfare

Abstract Conservation translocations are human‐mediated movements of wildlife for conservation purposes. They risk compromising the health of wildlife, and potentially domestic animals and humans, in the short and long term, but these risks vary with project context. Wildlife health risk analysis (disease risk analysis) is a process enabling these risks to be characterized and managed; multiple methods have been developed for conservation translocation. It would be beneficial for the depth of health risk analysis to be proportionate to context; however, few methods currently facilitate this flexibility. We aimed to produce a refined methodological framework for health risk analysis that enabled it to be scalable and adaptable to different translocation scenarios. We developed such a framework by adapting and assimilating elements of existing methods. We describe its key features and application to two wader (shorebird) conservation translocations with differing translocation plans and epidemiological circumstances. We then reflect on the framework's utility in light of the observed project outcomes, which exemplified the uncertain and changeable nature of disease risks over time. Our framework has the potential to expedite health risk analysis for repeat translocations of a particular taxon in a region and has application to other taxa and potentially other forms of wildlife translocation. 

Wildlife health risk analysis for conservation translocation: A scalable approach illustrated for wader population restoration

Introducción. El tronco arterial persistente es una rara malformación cardíaca congénita que provoca diversas complicaciones en el sistema cardiovascular. Se caracteriza por la presencia de un tabique ventricular defectuoso, una única válvula troncal y un tronco arterial común entre la arteria pulmonar y aorta, conllevando a una mezcla entre la sangre arterial y venosa, debido a un cortocircuito cardíaco bidireccional predominante de izquierda a derecha que compromete el suministro de flujo sanguíneo, nutrientes y oxigenación sistémica. Las manifestaciones clínicas incluyen desaturación con cianosis, hipoxemia, taquicardia, taquipnea, alteraciones en la contractilidad cardíaca, pulsos distales anómalos, pérdida de peso, fatiga y hepatomegalia.
Objetivo. El propósito de esta investigación es establecer hipótesis sobre los diversos mecanismos compensatorios que se activan a nivel sistémico para contrarrestar los efectos de esta malformación.
Reflexión. Se sugiere que se producen respuestas biomoleculares similares en los sistemas cardiovascular, pulmonar y renal, reduciendo la producción de óxido nítrico y provocando respuestas vasoconstrictoras. A nivel hepático, se generan factores de crecimiento y se inician procesos de angiogénesis para aumentar la perfusión sanguínea. En el cerebro, se activan enzimas para incrementar el flujo sanguíneo y proporcionar oxígeno y nutrientes esenciales.
Conclusión. A pesar de estos mecanismos compensatorios, no logran contrarrestar por completo las manifestaciones clínicas, conduciendo a una serie de problemas de salud, como hipertensión pulmonar, insuficiencia cardíaca, hepatomegalia, hipoperfusión de órganos y déficits neurológicos. Estos factores convergen para generar una compleja condición cardíaca que desencadena respuestas adaptativas en el cuerpo que terminan siendo una afección médica desafiante y potencialmente grave.

Mecanismos compensatorios a nivel sistémico en pacientes con tronco arterial persistente

The challenge of antimicrobial resistance (AMR) continues to receive significant global attention as common infections become increasingly resistant to the drugs used to treat them. Once an infectious microbe has developed a mechanism of resistance, it can cause longer, more damaging infections which are more costly, time-consuming, and sometimes impossible to treat. Such impacts occur across the health of humans, animals, plants, and the environment. Thus, AMR is considered a One Health issue. However, current narratives on AMR focus on humans, food-producing animals, crops, and their immediate environments. Very little attention is given to wildlife in terms of the impact of AMR on their health, nor their role in the evolution and spread of AMR. This article (1) discusses an absence of wildlife in current AMR guidance, (2) suggests how this absence of wildlife could limit understanding of, and action on, AMR, (3) proposes that considering AMR as a form of human-wildlife conflict could enable AMR guidance to better incorporate wildlife into action planning and create a truly One Health approach to tackle AMR.

Cancers occur across species. Understanding what is consistent and varies across species can provide new insights into cancer initiation and evolution, with significant implications for animal welfare and wildlife conservation. We built the pan-species cancer digital pathology atlas (PANCAD) and conducted the first pan-species study of computational comparative pathology using a supervised convolutional neural network algorithm trained on human samples. The artificial intelligence algorithm achieves high accuracy in measuring immune response through single-cell classification for two transmissible cancers (canine transmissible venereal tumour, 0.94; Tasmanian devil facial tumour disease, 0.88). Furthermore, in 18 other vertebrate species (mammalia=11, reptilia=4, aves=2, and amphibia=1), accuracy (0.57-0.94) was influenced by cell morphological similarity preserved across different taxonomic groups, tumour sites, and variations in the immune compartment. A new metric, named morphospace overlap, was developed to guide veterinary pathologists towards rational deployment of this technology on new samples. This study provides the foundation and guidelines for transferring artificial intelligence technologies to veterinary pathology based on a new understanding of morphological conservation, which could vastly accelerate new developments in veterinary medicine and comparative oncology.

Background
Truncus arteriosus (TA) or persistent arterial trunk describes the presence of a solitary arterial trunk arising from the base of the heart, supported by a common ventriculoarterial junction. The trunk gives rise to the coronary arteries, systemic arteries, and at least one pulmonary artery. Truncus arteriosus is a rare congenital cardiac disease, and even rarer is the absence of ventricular septal defect.


Case summary
We report a case of a 2-day-old infant who presented with cyanosis and a cardiac murmur. He was diagnosed with TA with intact ventricular septum (IVS), as well as crossed pulmonary arteries which was identified on pre-operative imaging. We describe the surgical management and short-term follow-up.


Discussion
Our clinical case demonstrates a unique diagnosis and management of TA with IVS identified by pre-operative imaging with good surgical outcome.

Ortner ’ s (or cardiovocal) syndrome is a rare condition which describes hoarseness due to left recurrent laryngeal nerve palsy caused by cardiovascular disease that is unrelated to surgery. This is a rare syndrome, seen more frequently in adult patients than in children. It has been theorised that either a dilated pulmonary artery (PA) or left atrial dilatation causes compression of the left recurrent laryngeal nerve. 1,2

The Wildlife Health Bridge was established in 2009 with the aim of improving the expertise and knowledge base of wildlife health professionals in biodiverse low- and middle-income countries. The Wildlife Health Bridge centres around partnerships among educational institutions: the Zoological Society of London, the Royal Veterinary College, the University of Edinburgh’s Royal (Dick) School of Veterinary Studies, the Wildlife Institute of India, and the University of Melbourne Veterinary School. The Wildlife Health Bridge provides quality education in wildlife health, ecosystem health, and wildlife biology, facilitates the interchange of students between collaborating countries for research studies and provides a global graduate network of wildlife health professionals. In addition to established Masters’ level wildlife health training programmes run by the partner organisations, the Wildlife Health Bridge has developed a collaborative field-based course, Interventions in Wild Animal Health, provided annually in India since 2016, which has trained 138 veterinarians to date, enhancing local and international capacity in managing emerging wildlife health issues and building global professional linkages. The Wildlife Health Bridge’s Wild Animal Alumni network facilitates networking and exchange between Wildlife Health Bridge institutions and graduates, with over 701 members from 67 countries, half of which are biodiverse low- and middle-income countries. Collaboration between educational institutions has enabled new ideas and ongoing developments in the delivery of materials and learning outcomes. The Wildlife Health Bridge is building global capacity in trained wildlife health professionals, through educational programmes and a synergised network, with the aim of impacting conservation practice to benefit human, domestic animal and wildlife health.
