RESUMEN
PURPOSE: The utilization of remote patient monitoring (RPM) with home blood pressure monitoring has shown improvement in blood pressure control and adherence with follow-up visits. Patient perceptions regarding its use in the obstetric population have not been widely studied. The aim of this study was to assess patients' knowledge about hypertensive disorders of pregnancy and perceptions and satisfaction of the RPM program. METHODS: Descriptive analysis of survey responses of patients with PPHTN enrolled into the RPM program for 6 weeks after delivery between October 2021 and April 2022. Surveys were automatically administered at 1-, 3-, and 6-week postpartum. Responses were further compared between Black and non-Black patient-reported race. RESULTS: 545 patients received the RPM program. Of these, 306 patients consented to data collection. At 1 week, 88% of patients that responded reported appropriately that a blood pressure greater than 160/110 is abnormal. At 3 weeks, 87.4% of patients responded reported they were "very" or "somewhat" likely to attend their postpartum follow-up visits because of RPM. At 6 weeks, 85.5% of the patients that responded were "very" or "somewhat" satisfied with the RPM program. Responses were not statistically different between races. CONCLUSIONS: Majority of postpartum patients enrolled in the RPM program had correct knowledge about hypertension. In addition, patients were highly satisfied with the RPM program and likely to attend postpartum follow-up based on responses. Further research is warranted to validate these findings and to address any barriers for patients who did not utilize the program.

Climate change is influencing polar bear (Ursus maritimus) habitat, diet, and behavior but the effects of these changes on their physiology is not well understood. Blood-based biomarkers are used to assess the physiologic health of individuals but their usefulness for evaluating population health, especially as it relates to changing environmental conditions, has rarely been explored. We describe links between environmental conditions and physiologic functions of southern Beaufort Sea polar bears using data from blood samples collected from 1984 to 2018, a period marked by extensive environmental change. We evaluated associations between 13 physiologic biomarkers and circumpolar (Arctic oscillation index) and regional (wind patterns and ice-free days) environmental metrics and seasonal and demographic co-variates (age, sex, season, and year) known to affect polar bear ecology. We observed signs of dysregulation of water balance in polar bears following years with a lower annual Arctic oscillation index. In addition, liver enzyme values increased over time, which is suggestive of potential hepatocyte damage as the Arctic has warmed. Biomarkers of immune function increased with regional-scale wind patterns and the number of ice-free days over the Beaufort Sea continental shelf and were lower in years with a lower winter Arctic oscillation index, suggesting an increased allocation of energetic resources for immune processes under these conditions. We propose that the variation in polar bear immune and metabolic function is likely indicative of physiologic plasticity, a response that allows polar bears to remain in homeostasis even as they experience changes in nutrition and habitat in response to changing environments.

Objective: Ultraviolet light (UV) is a risk factor for the development of cutaneous neoplasia in many mammalian species. This study evaluated UV exposure as a risk factor of concern for the development of cutaneous neoplasia in equine species due to the significant UV exposure that may accrue over their lifetimes. Animals and samples: Neoplastic biopsy specimens from 3272 horses that were submitted over a 10-year period to the Colorado State University Diagnostic Medicine Center and to the University of Saskatchewan Western College of Veterinary Medicine and Prairie Diagnostic Services were evaluated. Procedure: This retrospective study assessed the spatial relationships between altitude, latitude, longitude, and UV maximum value and the probability of UV-induced cutaneous neoplasia. Results: Cases from areas at high altitude proved to have a higher prevalence of UV-induced cutaneous neoplasia than those from areas at lower elevations. A multivariable regression analysis demonstrated that altitude was the only factor significantly and positively associated with the diagnosis of UV-induced neoplasia. Conclusion and clinical relevance: Evidence of cutaneous neoplasia in horses and environmental factors that influence the degree of UV exposure in a geographic location may aid in diagnosis and suggest preventive measures from UV overexposure.
Facteurs de risque environnementaux des néoplasies cutanées induites par les UV chez le cheval : une approche SIG. Objectif: La lumière ultraviolette (UV) est un facteur de risque pour le développement de néoplasies cutanées chez de nombreuses espèces de mammifères. Cette étude a évalué l'exposition aux UV en tant que facteur de risque préoccupant pour le développement de néoplasies cutanées chez les équidés en raison de l'exposition importante aux UV qui peut s'accumuler au cours de leur vie. Animaux et échantillons: Des échantillons de biopsie néoplasique de 3272 chevaux qui ont été soumis sur une période de 10 ans au Colorado State University Diagnostic Medicine Center et au University of Saskatchewan Western College of Veterinary Medicine and Prairie Diagnostic Services ont été évalués. Procédure: Cette étude rétrospective a évalué les relations spatiales entre l'altitude, la latitude, la longitude et la valeur maximale des UV et la probabilité de néoplasie cutanée induite par les UV. Résultats: Les cas des régions de haute altitude se sont avérés avoir une prévalence plus élevée de néoplasie cutanée induite par les UV que ceux des régions de basse altitude. Une analyse de régression multivariée a démontré que l'altitude était le seul facteur significativement et positivement associé au diagnostic de néoplasie induite par les UV. Conclusion et pertinence clinique: Les preuves de néoplasie cutanée chez les chevaux et les facteurs environnementaux qui influencent le degré d'exposition aux UV dans un lieu géographique peuvent aider au diagnostic et suggérer des mesures préventives contre la surexposition aux UV.(Traduit par Dr Serge Messier).

Competency-based veterinary education focuses on the knowledge and clinical skills required to generate a productive and confident practitioner. Accurate identification of clinically relevant core competencies enables academic institutions to prioritize which new and foundational information to cover in the limited time available. The goal of this study was to aggregate the opinions of veterinary practitioners about small animal core competencies in veterinary orthopedics. An online 20-question survey was distributed with questions regarding respondent demographics, education, practice type, caseload, involvement in orthopedic procedures, access to referral hospitals, frequency of orthopedic condition presentation and procedure performance, and proposed percent allocation of various orthopedic curriculum topics. Responses were included from 721 respondents, largely first-opinion veterinarians (81%, n = 580/721). The majority (58%; n = 418/721) of respondents performed less than 10% of the orthopedic surgeries themselves and, 37% (n = 266/721) reported never performing orthopedic surgery; of those performing surgeries, 78% (n = 354/455) performed less than six orthopedic procedures monthly. The five most common orthopedic conditions seen included: generalized osteoarthritis, patellar luxation, cranial cruciate ligament disease, hip dysplasia/arthritis, and muscle/tendon injuries. Median respondent scores for the percentage which a topic should comprise in an ideal orthopedic curriculum were 20% each for 'orthopedic exam' and for 'non-surgical orthopedic knowledge', 15% each for 'non-surgical orthopedic skills,' 'orthopedic imaging (radiographs),' and 'surgical orthopedic knowledge,' 10% for 'surgical orthopedic skills,' and 2% for 'advanced orthopedic imaging.' Based on these results, a curriculum focusing on the most clinically relevant orthopedic conditions with an emphasis on diagnosis establishment and non-surgical treatments is proposed.
RESUMEN
Exposure to air pollution, including criteria pollutants such as fine particulate matter (PM2.5) and ozone (O3), has been associated with morbidity and mortality in mammals. As a genetically homogenous population that is closely monitored for health, dairy cattle present a unique opportunity to assess the association between changes in air pollution and mammalian health. Milk yield decreases in the summer if temperature and humidity, measured by the Temperature Humidity Index (THI). As O3 levels increase with warmer temperatures, and summer PM2.5 may increase with wildfire smoke, dairy cows may serve as a useful sentinel species to evaluate subacute markers of inflammation and metabolic output and ambient pollution. Over two years, we assessed summertime O3 and PM2.5 concentrations from local US EPA air quality monitors into an auto-regressive mixed model of the association between THI and daily milk production data and bulk tank somatic cell count (SCC). In unadjusted models, a 10 unit increase THI was associated with 28,700 cells/mL (95% CI: 17,700, 39,690) increase in SCC. After controlling for ambient air pollutants, THI was associated with a 14,500 SCC increase (95% CI: 3,400, 25,680), a 48% decrease in effect compared to the crude model. Further, in fully adjusted models, PM2.5 was associated with a 105,500 cells/mL (95% CI: 90,030, 121,050) increase in SCC. Similar results were found for milk production. Results were amplified when high PM2.5 days (95th percentile of observed values) associated with wildfire smoke were removed from the analyses. Our results support the hypothesis that PM2.5 confounds the relationships between THI and milk yield and somatic cell count. The results of this study can be used to inform strategies for intervention to mitigate these impacts at the dairy level and potentially contribute to a model where production animals can act as air quality sentinels.

The COVID-19 pandemic has catalyzed the use of novel teaching modalities to enhance the provision of remote veterinary education. In this study, we describe the use of immersive virtual reality (iVR) as a teaching aid for veterinary medicine students during their orthopedics clinical rotation. Student sentiments were assessed using voluntary electronic surveys taken by veterinary students before and after the rotation. The most noteworthy benefits students reported were improved engagement with the course content, information retention, radiographic interpretation, and clinical reasoning skills. Obstacles encountered during the initial stages of the program included financial and temporal investment in equipment and content development, technical troubleshooting, and motion sickness. Though it is unlikely that iVR will ever fully replace hands-on learning experiences, it presents an educational opportunity to supplement traditional learning methods, motivate students, and fill information gaps. As iVR technology continues to evolve and improve, potential applications in the veterinary curriculum grow, making the modality's use progressively more advantageous. Although this study describes its application in an orthopedic setting, the versatility of the iVR modality lends the potential for it to be implemented in a number of clinical and didactic settings.

Climate change is one of the greatest public health threats of the twenty-first century. Recent surveys of veterinary students and practicing veterinarians have highlighted their concerns about the impacts of climate change on animal health and a strong desire to be knowledgeable about the practice and promotion of environmental sustainability within clinical practice. Most American Veterinary Medical Association (AVMA)-accredited veterinary schools have a veterinary teaching hospital (VTH) where veterinary students receive their core clinical education. Given this, VTHs may provide opportunities for students to learn how veterinary clinics can decrease their environmental footprint and actions they could incorporate into their future clinical work. To assess the feasibility of and support for introducing environmentally sustainable practices into VTHs, we distributed an anonymous online survey to all AVMA-accredited veterinary schools with an associated VTH. Responses were received from 843 individuals representing 23 VTHs in 7 countries. While the overwhelming majority of responding personnel believe this is an important topic, there is little evidence that sustainable behaviors are being practiced or showcased within VTHs. Respondents were most interested in working to increase recycling and reduce general waste and energy consumption within their hospitals. In addition to a lack of educational resources, funding was a commonly identified barrier to incorporating more environmentally sustainable practices. These results add to the growing evidence that enhanced incorporation of sustainability into veterinary medical education at all stages is needed and that VTHs provide a unique opportunity to lead by example.

Climate change poses a significant and increasing threat to global health. While veterinarians play integral roles in public and environmental health, the profession has been less engaged in the topic of climate change relative to their human medical counterparts. The objective of this study was to synthesize veterinary students' perceptions and knowledge about the relationship between veterinary medicine and climate change to identify educational gaps and opportunities. An online questionnaire was disseminated to American Veterinary Medical Association (AVMA)-accredited veterinary colleges through the Student American Veterinary Medical Association newsletter. Respondents were overwhelmingly confident that climate change is happening, is due to human activities, and is impacting both human and animal health. Veterinary students also expressed the belief that veterinarians should take a leadership role on the issue of climate change, especially through promoting environmental sustainability in clinical practice. Despite this enthusiasm, most students reported a lack of educational opportunities within their veterinary programs. The results of this survey highlight opportunities for the development of educational resources on the topic, many of which could complement existing material such as that devoted to practice management, economics, and client communication. Veterinarians have the potential to meaningfully contribute to both mitigation and adaptation efforts around climate change; however, they must be equipped with the tools to do so.

BACKGROUND: Regular physical activity (PA) promotes health and can prevent and treat diseases among both humans and dogs. Unfortunately, most U.S. adults do not meet PA recommendations, and many dogs are also insufficiently active. Veterinary-prescribed PA programs have shown some success in increasing activity among overweight dogs, but the impacts of such programs have not yet been tested for efficacy among otherwise-healthy dogs and owners. In addition, although wearable devices that monitor PA and provide individuals with feedback (e.g., progress toward a daily step goal) can effectively increase human PA, it is unclear what impact similar wearable devices have on human and dog PA when the PA-monitoring devices are worn by dogs. The present study assessed the impact of an 8-week veterinary-prescribed PA program on activity and health among dogs and their owners, and randomized participants (n = 59) to two groups: one in which PA was measured but not visible to participants (n = 30), and one in which PA was measured and real time feedback was visible through a wearable device (n = 29). RESULTS: Participants in both groups showed significant PA increases over the course of the 8-week program. Biomedical testing performed at the veterinary clinic facilitated early diagnosis of systemic illness in one human participant. The frequency of hypertension in human participants decreased significantly from baseline to the end of the program (week 8). Other health indices (e.g., BMI in humans, body weight and BCS in dogs) improved, albeit not to a statistically significant extent, over the course of the program. There were no significant differences on the outcomes of interest between the two experimental conditions. CONCLUSIONS: Veterinary-prescribed PA programs appear promising for increasing PA among insufficiently active but otherwise healthy dogs as well as their owners. Additional testing of veterinary-prescribed PA is warranted, particularly at other types of veterinary clinics (e.g., private practices). Incorporating wearable devices permitting owners to track canine PA did not appear necessary for obtaining these benefits; however, additional studies investigating alternative devices or different time periods may be warranted.

OBJECTIVE: To determine the influence of a novel surgical guide on the accuracy and technical difficulty of closing wedge osteotomies (CWO). STUDY DESIGN: Ex vivo experimental study. SAMPLE POPULATION: Canine tibia models (n = 40). METHODS: A 20° cranial CWO (CCWO) was created without (standard procedure; STCCWO) or with the aid of a novel wedge osteotomy guide (WOCCWO). Procedures were performed by diplomate (n = 4) and resident (n = 6) surgeons, with each performing 2 STCCWO followed by 2 WOCCWO. To prevent bias, surgeons were unaware of the study purpose until after completing the STCCWO. The wedges were evaluated by comparing the deviation from the 20° target angle, divergence of the 2 osteotomies (osteotomy divergence angle [ODA]), and measurements of the wedge height at the caudomedial cortex (CMC) and caudolateral cortex (CLC). Technique difficulty was explored through a surgeon questionnaire. RESULTS: The WOCCWO resulted in smaller mean ODA (WOCCWO = 0.86°, SD ± 0.38°, P < .001), and smaller mean difference between CMC and CLC (WOCCWO = 0.29 mm, SD ± 0.19, P < .001) than for the STCCWO (4.22°, SD ± 2.16° and 1.39 mm, SD ± 0.65 respectively). Deviation from the target 20° wedge angle was greater after STCCWO (1.46°, SD ± 1.27°) than after WOCCWO (0.53°, SD ± 0.33°, P = .004). No difference was reported regarding the difficulty of the procedures, but resident surgeons stated that they were more likely to use the guide in a clinical setting compared with diplomates. CONCLUSION: The wedge osteotomy guide improved the accuracy of CCWO compared with standard technique. CLINICAL SIGNIFICANCE: The clinical significance of the differences detected in this study is unclear and warrants in vivo investigation.

BACKGROUND: Accelerometer-based activity monitoring is a promising new tool in veterinary medicine used to objectively assess activity levels in dogs. To date, it is unknown how device orientation, attachment method, and attachment of a leash to the collar holding an accelerometer affect canine activity data. It was our goal to evaluate whether attachment methods of accelerometers affect activity counts. Eight healthy, client-owned dogs were fitted with two identical neck collars to which two identical activity monitors were attached using six different methods of attachment. These methods of attachment evaluated the use of a protective case, positioning of the activity monitor and the tightness of attachment of the accelerometer. Lastly, the effect of leash attachment to the collar was evaluated. For trials where the effect of leash attachment to the collar was not being studied, the leash was attached to a harness. Activity data obtained from separate monitors within a given experiment were compared using Pearson correlation coefficients and across all experiments using the Kruskal-Wallis Test. RESULTS: There was excellent correlation and low variability between activity monitors on separate collars when the leash was attached to a harness, regardless of their relative positions. There was good correlation when activity monitors were placed on the same collar regardless of orientation. There were poor correlations between activity monitors in three experiments: when the leash was fastened to the collar that held an activity monitor, when one activity monitor was housed in the protective casing, and when one activity monitor was loosely zip-tied to the collar rather than threaded on using the provided metal loop. Follow-up, pair-wise comparisons identified the correlation associated with these three methods of attachment to be statistically different from the level of correlation when monitors were placed on separate collars. CONCLUSIONS: While accelerometer-based activity monitors are useful tools to objectively assess physical activity in dogs, care must be taken when choosing a method to attach the device. The attachment of the activity monitor to the collar should utilize a second, dedicated collar that is not used for leash attachment and the attachment method should remain consistent throughout a study period.

BACKGROUND: Accelerometers are motion-sensing devices that have been used to assess physical activity in dogs. However, the lack of a user-friendly, inexpensive accelerometer has hindered the widespread use of this objective outcome measure in veterinary research. Recently, a smartphone-based, affordable activity monitor (Whistle) has become available for measurement of at-home physical activity in dogs. The aim of this research was to evaluate this novel accelerometer. Eleven large breed, privately owned dogs wore a collar fitted with both the Whistle device and a previously validated accelerometer-based activity monitor (Actical) for a 24-h time period. Owners were asked to have their dogs resume normal daily activities. Total activity time obtained from the Whistle device in minutes was compared to the total activity count from the Actical device. Activity intensity from the Whistle device was calculated manually from screenshots of the activity bars displayed in the smartphone-application and compared to the activity count recorded by the Actical in the same 3-min time period. RESULTS: A total of 3740 time points were compared. There was a strong correlation between activity intensity of both devices for individual time points (Pearson's correlation coefficient 0.81, p < 0.0001). An even stronger correlation was observed between the total activity data between the two devices (Pearson's correlation coefficient 0.925, p < 0.0001). CONCLUSIONS: Activity data provided by the Whistle activity monitor may be used as an objective outcome measurement in dogs. The total activity time provided by the Whistle application offers an inexpensive method for obtaining at-home, canine, real-time physical activity data. Limitations of the Whistle device include the limited battery life, the need for manual derivation of activity intensity data and data transfer, and the requirement of Wi-Fi and Bluetooth availability for data transmission.

Valvular endocarditis has been well described in northern sea otters Enhydra lutris kenyoni of Alaska and in many cases no cause has been identified. It is also one of the most common conditions observed in people with chronic Coxiella burnetii infection. Given the high levels of C. burnetii exposure in marine mammals distributed throughout the same geographic range as the northern sea otter, and the presence of valvular lesions seen in otters, the objective of this study was to determine the level of C. burnetii exposure in otters and investigate any association between exposure, infection and valvular disease in this species. Archived serum from 75 live captured, apparently healthy otters (25 from each of 3 stocks) and 30 dead otters were tested for C. burnetii antibodies by indirect florescent antibody assay (IFA). Archived bone marrow and heart valves were tested for C. burnetii DNA by real-time PCR (qPCR). Overall, the seroprevalence in live otters was 17%, with significantly more exposed animals in the south central (40%) stock relative to the southwest (8%) and southeast (4%). The seroprevalence of animals sampled post mortem was 27%, although none of the bone marrow or heart valve samples were positive by qPCR. Results of this study failed to demonstrate a significant association between C. burnetii infection and valvular endocarditis in sea otters; however, the differing seroprevalence suggests that exposure opportunities vary geographically.

OBJECTIVES: To report our experience with thoracoscopic lung lobectomy in dogs with primary lung tumors and compare the long-term outcome between dogs with primary lung tumors treated with lobectomy via thoracoscopy or thoracotomy. STUDY DESIGN: Retrospective case series; case-control study. ANIMALS: Thirteen dogs with primary lung tumors treated with thoracoscopic lung lobectomy; case-matched cohort of 9 dogs with primary lung tumors treated with lobectomy via thoracotomy. METHODS: Medical records from dogs that underwent thoracoscopic lung lobectomy at a single institution were reviewed. Only cases with primary lung tumors were included. Surgical complications and conversion rate were reported. Cases without conversion and with clean margins on histologic examination were matched on prognostic criteria to cases with primary lung tumors treated with lobectomy via thoracotomy. Survival was compared between thoracoscopy and thoracotomy. RESULTS: Thirteen dogs with primary lung tumors that measured 2.2-7 cm underwent thoracoscopic lung lobectomy. Nine dogs were diagnosed with carcinoma and 4 with histiocytic sarcoma. There were 3 conversions to open thoracotomy because of poor visualization. There were no differences in short-term outcome between dogs that had their procedures completed via thoracoscopy and those that were converted to thoracotomy. Nine dogs with clean margins were matched with 9 dogs treated via thoracotomy. Mean (standard deviation) followup was 367 (327) days for dogs undergoing thoracoscopy and 603 (612) days for dogs undergoing thoracotomy. The 2-year survival rate was 44% for thoracoscopy and 56% for thoracotomy (P = .942). CONCLUSION: Selected primary lung tumors in dogs can be safely resected with thoracoscopy and not affect long-term outcome.

OBJECTIVE: To determine if use of various commonly practiced tibial tuberosity advancement (TTA) preoperative planning methods leads to variable TTA cage size recommendations. STUDY DESIGN: Radiographic study. ANIMALS: Dogs (n = 14) with naturally occurring cranial cruciate ligament disease. METHODS: TTA was planned by a single observer on mediolateral stifle radiographs of each dog using 2 sets of tibial plateau landmarks (anatomic [A] vs. femorotibial common tangent [T]) and 2 advancement measurement techniques (transparent overlay [O] vs. simulated TTA using imaging software [S]) for 4 different planning methods (AO, AS, TO, TS). Cage size recommendations for each stifle were tabulated for each of the 4 planning methods. Mean advancement (mm) required to obtain patellar tendon angle (PTA) = 90° for each of the 4 planning methods were statistically compared. RESULTS: In the 14 stifles studied, the 4 planning methods evaluated led to 4 different cage size recommendations in 1 stifle, 3 different recommendations in 8 stifles, 2 different recommendations in 3 stifles, and 1 recommendation in only 2 stifles. There was a significant difference in the mean advancement measurement between the 4 planning methods (P < .0001); the AS technique was the largest whereas TO resulted in the smallest measurement. Overall, larger advancement was associated with use of anatomic landmarks (vs. common tangent) and imaging software to simulate TTA (vs. overlays). CONCLUSION: Currently practiced methods for TTA pre-planning led to variable cage size recommendations in 86% of the stifles evaluated and may be a source of inconsistent functional outcomes.

OBJECTIVE: To report clinical and histopathologic features of long digital extensor (LDE) tendon mineralization with concurrent cranial cruciate ligament (CCL) rupture in a dog. STUDY DESIGN: Case report. ANIMAL: 1.5-year-old, male castrated, English bulldog mix weighing 31.5 kg. METHODS: Pre- and postoperative orthogonal radiographs, arthroscopic evaluation, arthrotomy with en bloc surgical excision, and histopathologic analysis of the excised LDE tendon. RESULTS: There was radiographic evidence of mineralization in the region of the proximal LDE and stifle instability suggestive of CCL rupture. Arthroscopy, and subsequent arthrotomy, showed complete tearing of the CCL and an intact but grossly thickened LDE. No evidence of avulsion or bony proliferation associated with the LDE was appreciated. Tibial plateau leveling osteotomy (TPLO) and tenectomy of the LDE returned the dog to normal weight-bearing. No evidence of ectopic mineralization in the affected limb or similar clinical signs in the contralateral limb have been observed in 12 months follow-up. CONCLUSIONS: LDE tenectomy followed by stabilization of the stifle by TPLO resulted in a functional outcome. Mineralization without concurrent avulsion of the LDE has not been reported in dogs; however, posterolateral tendon injury in people has been linked to knee instability and cruciate ligament rupture.

OBJECTIVE: To determine the incidence of fibular penetration during placement of the Synthes® locking TPLO plate with and without the use of a jig. STUDY DESIGN: Cadaveric, experimental study. SAMPLE POPULATION: Cadaveric paired pelvic limbs (n = 8) from skeletally mature dogs. METHODS: Limbs were assigned to 1 of 2 groups (jig-less-TPLO = no jig used; jig-TPLO = jig used). Synthes® locking TPLO plates were applied using proximal screws of excessive length to facilitate identification of fibular penetration. Screw tip locations were identified by dissection and frequency of fibular penetration was compared between groups. RESULTS: None of the jig-TPLO limbs and 6 (75%) of jig-less-TPLO limbs had fibular penetration, a difference that was statistically significant. Fibular penetration was most frequently associated with the most proximal screw. CONCLUSIONS: A significantly higher incidence of fibular penetration occurs when Synthes® locking TPLO is performed without use of a jig.

BACKGROUND: Limited research exists on impacts of air pollution on non-human mammals, particularly animal athletes such as Thoroughbred racehorses. Athletes have a greater risk of exposure as heightened exertion and increased airflow carry more pollutants deeper into the respiratory tract. OBJECTIVES: To provide insights into the impact of ambient air pollution, particularly fine particulate matter (PM2.5), on race speed. STUDY DESIGN: Retrospective observational study. METHODS: Data were obtained from The Jockey Club Information Systems, covering 31 407 winning races by Thoroughbred horses in California spanning 10 years (2011-2020) and evaluated the association between air pollution and winning race speeds. For race days, we collected PM2.5 data from the nearest U.S. Environmental Protection Agency (EPA) monitoring site within 100 km of each racetrack (n = 12). We assessed the associations between daily average PM2.5 concentrations and speed of winning horses with linear mixed effects regression. We adjusted for horse characteristics, race-related covariates, temporal indicators (e.g., year), other air pollutants and temperature. We conducted sensitivity analyses by adjusting extreme air pollution days by reassigning values to the 95th percentile value and conducting linear mixed effects regression on series of datasets with incremental cutpoints of PM2.5. RESULTS: In the cutpoint analysis, we found that for PM2.5 between 4 and 23.6 µg/m3, speed decreased 0.0008 m/s (95% CI: -0.0014562 to -0.00018) for every 1 µg/m3 increase of PM2.5. MAIN LIMITATIONS: Limitations include the use of offsite monitors leading to imprecise exposure measurements, not using training practice data, and generalisability as the study focuses on California racetracks. CONCLUSION: This study highlights the need to create advisories to safeguard the performance of horses during periods of poor air quality. Further research is recommended to explore additional factors influencing the relationship between air pollution and equine welfare.
RESUMEN
BACKGROUND: Misinformation presents a critical concern for academic and public health discourse, particularly around vaccine response. Before the COVID-19 pandemic, vaccine hesitancy was responsible for decreased immunization uptake for vaccine-preventable diseases. Misinformation connected to the novel COVID-19 vaccine has further fueled vaccine hesitancy in Colorado and the United States. Our study brings together three different perspectives - physicians, public health professionals, and parents - to understand the impact of misinformation on vaccine uptake in Colorado. Our study proposes a framework for combining the Health Belief Model with the Socio-Ecological model to account for societal factors in healthcare decision making. METHODS: Semi-structured interviews and focus groups with public health professionals, physicians, and parents (n = 31) were conducted in late spring and summer 2022. Data were coded inductively using thematic analysis. Identified themes were deductively categorized according to the Socio-Ecological Model and Health Belief Model. RESULTS: Using a theoretical framework that combined the Health Belief Model and the Socio-Ecological Model, we identified seven factors that influenced vaccine hesitancy in Colorado. Intrapersonal factors included routine vaccine hesitancy connected to perceptions of severity and susceptibility, efficacy, and benefits and barriers to vaccine uptake; interpersonal factors included social networks; institutional factors included mass mediated platforms, portrayals of uncertainty, distrust in institutional sources of information, and political influences in vaccine decision making; and structural factors included economic barriers behind vaccine hesitancy. CONCLUSIONS: Our study provides a unique, triangulated, post-positivist perspective on the role of misinformation in vaccine hesitancy in Colorado. The findings provide evidence that misinformation is an important barrier to vaccination uptake and can permeate multiple socio-ecological determinants/characteristics to influence vaccination behaviors including intrapersonal, interpersonal, institutional, and structural levels. We introduce the Social Ecology of Health Beliefs and Misinformation Framework to account for how misinformation may interrupt vaccine uptake.
