RESUMO
A successful clinical trial requires participants, but many factors can impede effective study recruitment. To better recruit for quality veterinary clinical trials in client-owned animals that lead to improved evidence-based patient care and outcomes, there is a collective need to share and implement current best practices for recruitment strategies. These strategies should utilize a holistic view of recruitment, encompassing study design and logistics, representative participation, incentives, personnel resources, advertising, and participant retention. Although human clinical trial data and resources can provide guidance, effort also needs to be put into evaluating current practices and opportunities for process improvement that are specific to the conduct of veterinary clinical trials. Considering the power of pets as naturally occurring models of disease and as sentinels, improved conduct of veterinary clinical research has the potential to inform human health outcomes. Continued development of collaborations surrounding best practices and training opportunities in veterinary clinical research will improve the impact of veterinary clinical trials teams, while also promoting workforce development and alternate career paths for veterinary professionals.
RESUMO
Despite a pressing need for new therapies to address unmet veterinary medical need, no approved stem cell products are available for use in cats in the US. To evaluate the current state of mesenchymal stem or stromal cell (MSC) research in cats, a scoping review of published literature was performed, which identified 108 publications related to feline MSCs. Twenty-six of the articles described administration of MSC products to a total of 215 cats. Twelve of the studies included a control group. These experimental and clinical trials used 7 cell sources, 9 administration routes, 12 delivery vehicles, and a 300-fold range in dosages for initial studies in healthy cats and cats with 12 naturally occurring and induced diseases. The majority of studies administered 2 doses of allogeneic, adipose-derived MSC IV and monitored a median of 6.5 treated cats for a median of 90 days. The majority (150/215 [69.8%]) of cats had no reported adverse events associated with treatment. Although an increase in feline MSC publications in the past 10 years indicates progress, the wide variety and small number of studies using MSCs and MSC products in cats demonstrates that current evaluations are mostly still in the discovery phase, and several issues remain related to larger scale trials using MSC products in cats. The current available publications provide information to direct further clinical study development and informed owner consent for study enrollment.

A scoping review of published literature found 108 articles related to mesenchymal stem or stromal cell (MSC) use in cats. Twenty-four of the publications summarized the treatment of 192 cats with MSC products for 12 naturally occurring and induced diseases. These trials used a variety of cell sources, administration routes, delivery vehicles, and dosages. The majority of studies did not have a control group. The disease with the largest number of cats administered MSCs thus far is chronic kidney disease (n = 59 cats). The majority of cats had no adverse events associated with treatment, which supports continued interest in the potential use of MSC products to address unmet medical needs. Treatment outcomes of the 192 cats have ranged from no response to long-term cure, depending on the disease being treated and the particular study. Some of these early studies show promise and provide significant information to direct both the design and focus of larger clinical trials investigating the safety and efficacy of MSC treatment for veterinary and human applications.

OBJECTIVE: To investigate the prevalence and seropositivity of SARS-CoV-2 in companion and exotic animals in a veterinary healthcare system. SAMPLE: A total of 341 animals were sampled by a combination of oral and nasal swabs. Serum from whole blood was collected from a subset of animals (86 canines, 25 felines, and 6 exotic animals). METHODS: After informed owner consent, convenience samples from client-owned animals and the pets of students and staff members associated with Colorado State University's Veterinary Health System were collected between May 2021 and September 2022. Study samples were collected by trained veterinarians, Veterinary Health System staff, and veterinary students. RESULTS: SARS-CoV-2 RNA was detected by reverse transcription PCR in 1.6% (95% CI, 0.5% to 4.6%) of domestic canines and 1.1% (95% CI, 0.2% to 6.1%) of domestic felines. No RNA was detected in any of the exotic animal species tested (n = 66). Plaque reduction neutralization tests indicated that 12.8% (95% CI, 7.3% to 21.5%) of canines and 12.0% (95% CI, 4.2% to 30.0%) of felines had neutralizing antibodies against SARS-CoV-2. CLINICAL RELEVANCE: This study provides insight regarding SARS-CoV-2 spillover in domestic companion and exotic animals and contributes to our understanding of transmission risk in the veterinary setting.

OBJECTIVE: To investigate the effects of hemorrhagic shock and fresh whole blood resuscitation on the microcirculation and endothelial glycocalyx using sidestream dark field (SDF) imaging and plasma biomarkers. ANIMALS: 8 purpose-bred dogs. METHODS: Pressure-targeted hemorrhagic shock was induced in anesthetized dogs. SDF measurement of perfused boundary region and microcirculatory variables (RBC flow, total vessel density, and relative and absolute capillary blood volume), biomarker measurement (heparan sulfate, hyaluronan, VE-cadherin, and syndecan-1), mean arterial blood pressure, and cardiac output measurement were performed before anesthesia (TP0), after induction (TP1), after hemorrhagic shock (TP2), and after 50% retransfusion (TP3) and 100% retransfusion (TP4). RESULTS: At TP1, TP2, TP3, and TP4, mean arterial blood pressure was 74.25 ± 7.17 mm Hg, 49.50 ± 13.74 mm Hg, 63.50 ± 13.29 mm Hg, and 71.38 ± 8.77 mm Hg, and cardiac output was 2.57 ± 1.01 L/min, 0.8 ± 0.36 L/min, 1.81 ± 0.57 L/min, and 2.93 ± 1.22 L/min, respectively. Heparan sulfate, hyaluronan, syndecan-1, and VE-cadherin ranges were 24.80 to 77.72 ng/mL, 5.77 to 105.06 ng/mL, below detection to 1,545.69 pg/mL, and 0 to 2.52 ng/mL, respectively. Perfused boundary region, RBC flow, total vessel density, and relative and absolute capillary blood volume ranges were 1.75 to 2.68 µm, 89.6 to 584.5 µm/s, 51.7 to 1,914.3 mm/m2, 0.94 to 1.53 103 µm3, and 1.50 to 94.30 103 µm3, respectively. Heparan sulfate decreased significantly over time (P = .016). No significant differences were found for microcirculatory variables, perfused boundary regions, or other biomarkers. CLINICAL RELEVANCE: This was the first study to assess microvascular dysfunction and endothelial shedding in a canine hemorrhagic shock model using SDF microscopy (Glycocheck) and plasma biomarkers. Further studies are needed to determine clinical relevance.

BACKGROUND: Owner comprehension is vital to recruitment and study success, but limited information exists regarding the readability of public-facing veterinary clinical trial descriptions. OBJECTIVES: The current study sought to evaluate the readability of public-facing online veterinary clinical trial descriptions from academic institutions and private referral practices. ANIMALS: None. METHODS: This prospective study assessed readability in a convenience sample of veterinary clinical trial study descriptions using 3 common methods: the Flesch-Kincaid Grade Level (F-K), Flesch Reading Ease Score (FRES), and online Automatic Readability Checker (ARC). Results were compared across specialties and between academic and private institutions. RESULTS: Grade level and readability consensus scores (RCSs) were obtained for 61 online clinical trial descriptions at universities (n = 49) and private practices (n = 12). Average grade-level RCS for study descriptions was 14.13 (range, 9-21). Using Microsoft Word, the FRES score was higher in descriptions from universities compared to private practices (P = .03), and F-K scores were lower in university compared to private practice descriptions (P = .03). FRES (P = .07), F-K (P = .12), and readability consensus (P = .17) scores obtained from ARC were not different between institution types. Forty-eight studies (79%) had RCSs over 12, equivalent to reading material at college or graduate school levels. CONCLUSIONS AND CLINICAL IMPORTANCE: Similar to other areas in veterinary communication, the evaluated veterinary clinical trial descriptions used for advertising and recruitment far exceeded the recommended 6th-grade reading level for medical information. Readability assessments are straightforward to conduct, and ensuring health literacy should be a customary best practice in veterinary medicine and clinical research.

Introduction: Intraosseous (IO) catheterization enables rapid access to systemic circulation in critical patients. A battery-powered IO device (BPIO) utilized in veterinary practice is reliable in facilitating IO catheter placement. A new spring-powered IO device (SPIO) has been developed for people but has not been tested in veterinary patients. The goal of our study was to compare placement characteristics and flow rates achieved with the BPIO compared to the SPIO in animals when operated by novice users. Methods: Six veterinary students performed 72 catheterizations in the humeri and tibias of 12 dog and 6 cat cadavers. The user, cadaver, device, and site of placement were randomized. Flow rates were determined by three-minute infusions. Results: In dogs, overall success rates (50% BPIO, 46% SPIO; p = 0.775) and flow rates based on location were similar between devices. Successful placement was faster on average with the BPIO (34.4 s for BPIO and 55.0 s for SPIO, p = 0.0392). However, time to successful placement between devices was not statistically significant based on location (humerus: 34.7 s for BPIO and 43.1 s for SPIO, p = 0.3329; tibia: 33.3 s for BPIO and 132.6 s for SPIO, p = 0.1153). In cats, success rates were similar between devices (16.7% for BPIO and 16.7% for SPIO, p = 1.000), but limited successful placements prevented further analysis. Discussion: This is the first study to examine the use of the SPIO in animals, providing preliminary data for future IO studies and potential applications for training in the clinical setting.
RESUMO
PURPOSE: To update the ASCO guideline (2018) on the practical assessment and management of age-associated vulnerabilities in older patients undergoing systemic cancer therapy. METHODS: An Expert Panel conducted a systematic review to identify relevant randomized clinical trials (RCTs), systematic reviews, and meta-analyses from January 2016 to December 2022. RESULTS: A total of 26 publications met eligibility criteria and form the evidentiary basis for the update. RECOMMENDATIONS: The Expert Panel reiterates its overarching recommendation from the prior guideline that geriatric assessment (GA), including all essential domains, should be used to identify vulnerabilities or impairments that are not routinely captured in oncology assessments for all patients over 65 years old with cancer. Based on recently published RCTs demonstrating significantly improved clinical outcomes, all older adults with cancer (65+ years old) receiving systemic therapy with GA-identified deficits should have GA-guided management (GAM) included in their care plan. GAM includes using GA findings to inform cancer treatment decision-making as well as to address impairments through appropriate interventions, counseling, and/or referrals. A GA should include high priority aging-related domains known to be associated with outcomes in older adults with cancer: physical and cognitive function, emotional health, comorbid conditions, polypharmacy, nutrition, and social support. Clinical adaptation of the GA based on patient population, resources, and time is appropriate.The Panel recommends the Practical Geriatric Assessment as one option for this purpose (https://old-prod.asco.org/sites/new-www.asco.org/files/content-files/practice-patients/documents/2023-PGA-Final.pdf; https://youtu.be/jnaQIjOz2Dw; https://youtu.be/nZXtwaGh0Z0).Additional information is available at www.asco.org/supportive-care-guidelines.

The world is losing wildlife species at an unprecedented rate. Habitat destruction, overexploitation, and pollution are the leading causes of biodiversity decline. As a threat multiplier, climate change exacerbates these processes as demonstrated by the death of several billion wild animals in the last few years from wildfires, floods, heatwaves, and other natural disasters. In the face of these challenges, veterinarians have unique and important skillsets to contribute to wildlife conservation and the preservation of biodiversity at many levels. Veterinarians can organize and train to mobilize wildlife extraction, rescue, and rehabilitation units during natural disasters as well as build relationships with rehabilitators to provide their services for general wildlife rehabilitation needs. They can work in transdisciplinary teams to provide veterinary expertise for ecosystem health and rewilding projects. They can become sustainability champions by providing pollinator and wildlife friendly habitats at their clinics and reducing clinic waste and energy consumption, and they can engage in science communication and advocacy. When provided with the necessary information, resources, and action items, veterinarians can increase their positive impact and personal well-being through purposeful, value-driven, community-building efforts to support wildlife conservation and biodiversity.

Introduction: Post-acute sequelae of COVID-19 affects the quality of life of many COVID-19 survivors, yet the etiology of post-acute sequelae of COVID-19 remains unknown. We aimed to determine if persistent inflammation and ongoing T-cell activation during convalescence were a contributing factor to the pathogenesis of post-acute sequelae of COVID-19. Methods: We evaluated 67 individuals diagnosed with COVID-19 by nasopharyngeal polymerase chain reaction for persistent symptoms during convalescence at separate time points occurring up to 180 days post-diagnosis. Fifty-two of these individuals were evaluated longitudinally. We obtained whole blood samples at each study visit, isolated peripheral blood mononuclear cells, and stained for multiple T cell activation markers for flow cytometry analysis. The activation states of participants' CD4+ and CD8+ T-cells were next analyzed for each of the persistent symptoms. Results: Overall, we found that participants with persistent symptoms had significantly higher levels of inflammation at multiple time points during convalescence when compared to those who fully recovered from COVID-19. Participants with persistent dyspnea, forgetfulness, confusion, and chest pain had significantly higher levels of proliferating effector T-cells (CD8+Ki67+), and those with chest pain, joint pain, difficulty concentrating, and forgetfulness had higher levels of regulatory T-cells (CD4+CD25+). Additionally, those with dyspnea had significantly higher levels of CD8+CD38+, CD8+ Granzyme B+, and CD8+IL10+ cells. A retrospective comparison of acute phase inflammatory markers in adults with and without post-acute sequelae of COVID-19 showed that CD8+Ki67+ cells were significantly higher at the time of acute illness (up to 14 days post-diagnosis) in those who developed persistent dyspnea. Discussion: These findings suggest continued CD8+ T-cell activation following SARS-CoV-2 infection in adults experiencing post-acute sequelae of COVID-19 and that the increase in T regulatory cells for a subset of these patients represents the ongoing attempt by the host to reduce inflammation.

Vitamin D deficiency is common in the United States and leads to altered immune function, including T cell and macrophage activity that may impact responses to SARS-CoV-2 infection. This study investigated 131 adults with a history of a positive SARS-CoV-2 nasopharyngeal PCR and 18 adults with no COVID-19 diagnosis that were recruited from the community or hospital into the Northern Colorado Coronavirus Biorepository (NoCo-COBIO). Participants consented to enrollment for a period of 6 months and provided biospecimens at multiple visits for longitudinal analysis. Plasma 25-hydroxyvitamin D levels were quantified by LC-MS/MS at the initial visit (n = 149) and after 4 months (n = 89). Adults were classified as deficient (<30 nM or <12 ng/mL), insufficient (<30−50 nM or 12−20 ng/mL), or optimal (50−75 nM or >20 ng/mL) for 25-hydroxyvitamin D status. Fisher's exact test demonstrated an association between disease severity, gender, and body mass index (BMI) at baseline. Mixed model analyses with Tukey-Kramer were used for longitudinal analysis according to BMI. Sixty-nine percent (n = 103) of the entire cohort had optimal levels of total 25(OH)D, 22% (n = 32) had insufficient levels, and 9% (n = 14) had deficent levels. Participants with severe disease (n = 37) had significantly lower 25-hydroxyvitamin D (total 25(OH)D) when compared to adults with mild disease (p = 0.006) or no COVID-19 diagnosis (p = 0.007). There was 44% of the cohort with post-acute sequalae of COVID-19 (PASC) as defined by experiencing at least one of the following symptoms after 60 days' post-infection: fatigue, dyspnea, joint pain, chest pain, forgetfulness or absent-mindedness, confusion, or difficulty breathing. While significant differences were detected in 25-hydroxyvitamin D status by sex and BMI, there were no correlations between 25-hydroxyvitamin D for those without and without PASC. This longitudinal study of COVID-19 survivors demonstrates an important association between sex, BMI, and disease severity for 25-hydroxyvitamin D deficiency during acute stages of infection, yet it is not clear whether supplementation efforts would influence long term outcomes such as developing PASC.

Background: SARS-CoV-2 has infected millions across the globe. Many individuals are left with persistent symptoms, termed post-acute sequelae of COVID-19 (PASC), for months after infection. Hyperinflammation in the acute and convalescent stages has emerged as a risk factor for poor disease outcomes, and this may be exacerbated by dietary inadequacies. Specifically, fatty acids are powerful inflammatory mediators and may have a significant role in COVID-19 disease modulation. Objective: The major objective of this project was to pilot an investigation of plasma fatty acid (PFA) levels in adults with COVID-19 and to evaluate associations with disease severity and PASC. Methods and procedures: Plasma from adults with (N = 41) and without (N = 9) COVID-19 was analyzed by gas chromatography-mass spectrometry (GC-MS) to assess differences between the concentrations of 18 PFA during acute infection (≤14 days post-PCR + diagnosis) in adults with varying disease severity. Participants were grouped based on mild, moderate, and severe disease, alongside the presence of PASC, a condition identified in patients who were followed beyond acute-stage infection (N = 23). Results: Significant differences in PFA profiles were observed between individuals who experienced moderate or severe disease compared to those with mild infection or no history of infection. Palmitic acid, a saturated fat, was elevated in adults with severe disease (p = 0.04), while behenic (p = 0.03) and lignoceric acid (p = 0.009) were lower in adults with moderate disease. Lower levels of the unsaturated fatty acids, γ-linolenic acid (GLA) (p = 0.03), linoleic (p = 0.03), and eicosapentaenoic acid (EPA) (p = 0.007), were observed in adults with moderate disease. Oleic acid distinguished adults with moderate disease from severe disease (p = 0.04), and this difference was independent of BMI. Early recovery-stage depletion of GLA (p = 0.02) and EPA (p = 0.0003) was associated with the development of PASC. Conclusion: Pilot findings from this study support the significance of PFA profile alterations during COVID-19 infection and are molecular targets for follow-up attention in larger cohorts. Fatty acids are practical, affordable nutritional targets and may be beneficial for modifying the course of disease after a COVID-19 diagnosis. Moreover, these findings can be particularly important for overweight and obese adults with altered PFA profiles and at higher risk for PASC. Clinical trial registration: [ClinicalTrials.gov], identifier [NCT04603677].
RESUMO
OBJECTIVES: The objective of this study was to compare the efficacy of feline mesenchymal stem cells (fMSC) with prednisolone as a treatment for inflammatory bowel disease (IBD) in cats. METHODS: Cats with chronic enteropathy that failed a 2-week diet trial and were not found to have significant concurrent disease were eligible for the study. If endoscopic biopsies confirmed a histopathologic diagnosis of IBD, the cat was randomly assigned to either the fMSC or prednisolone groups. Owners were blinded to the grouping. Stem cell treatment consisted of two intravenous injections of 2 × 106 cells/kg of freshly cultured allogeneic stem cells separated by 2 weeks. Prednisolone treatment was 1-2 mg/kg PO q24h, tapered according to clinical response. Owners were asked to make no changes (eg, diet and other medications) for the first 2 months, at which time they either continued to the 6-month recheck with no changes, or 'failed' treatment and owners were unblinded and changes made as necessary. RESULTS: Six prednisolone and six fMSC treatment cats completed the study. All six prednisolone group cats were spayed females with a mean age of 8.3 years (range 2-14), a mean body weight of 3.6 kg (range 2.5-4.8) and a mean pretreatment Feline Chronic Enteropathy Activity Index (FCEAI) score of 3.6 (range 2-6). The six stem cell cats included three spayed females and three castrated males, and had a mean age of 8.0 years (range 4.5-13), a mean body weight of 4.9 kg (range 4.0-5.9) and a mean pretreatment FCEAI score of 3.7 (range 2-5). One cat in each group failed at the 2-month recheck. At the 6-month recheck, the mean FCEAI score for the prednisolone group was 3.7 (range 0.5-9) and 0.75 (range 0-1.5) for the fMSC group. CONCLUSIONS AND RELEVANCE: These results suggest that this specific fMSC protocol appears to be as effective in the treatment of feline IBD as a standard course of prednisolone therapy.

Immune response dysregulation plays a key role in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogenesis. In this study, we evaluated immune and endothelial blood cell profiles of patients with coronavirus disease 2019 (COVID-19) to determine critical differences between those with mild, moderate, or severe COVID-19 using spectral flow cytometry. We examined a suite of immune phenotypes, including monocytes, T cells, NK cells, B cells, endothelial cells, and neutrophils, alongside surface and intracellular markers of activation. Our results showed progressive lymphopenia and depletion of T cell subsets (CD3+, CD4+, and CD8+) in patients with severe disease and a significant increase in the CD56+CD14+Ki67+IFN-γ+ monocyte population in patients with moderate and severe COVID-19 that has not been previously described. Enhanced circulating endothelial cells (CD45-CD31+CD34+CD146+), circulating endothelial progenitors (CD45-CD31+CD34+/-CD146-), and neutrophils (CD11b+CD66b+) were coevaluated for COVID-19 severity. Spearman correlation analysis demonstrated the synergism among age, obesity, and hypertension with upregulated CD56+ monocytes, endothelial cells, and decreased T cells that lead to severe outcomes of SARS-CoV-2 infection. Circulating monocytes and endothelial cells may represent important cellular markers for monitoring postacute sequelae and impacts of SARS-CoV-2 infection during convalescence and for their role in immune host defense in high-risk adults after vaccination.

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.

In the past decade, the potential to translate scientific discoveries in the area of regenerative therapeutics in veterinary species to novel, effective human therapies has gained interest from the scientific and public domains. Translational research using a One Health approach provides a fundamental link between basic biomedical research and medical clinical practice, with the goal of developing strategies for curing or preventing disease and ameliorating pain and suffering in companion animals and humans alike. Veterinary clinical trials in client-owned companion animals affected with naturally occurring, spontaneous disease can inform human clinical trials and significantly improve their outcomes. Innovative cell therapies are an area of rapid development that can benefit from non-traditional and clinically relevant animal models of disease. This manuscript outlines cell types and therapeutic applications that are currently being investigated in companion animals that are affected by naturally occurring diseases. We further discuss how such investigations impact translational efforts into the human medical field, including a critical evaluation of their benefits and shortcomings. Here, leaders in the field of veterinary regenerative medicine argue that experience gained through the use of cell therapies in companion animals with naturally occurring diseases represent a unique and under-utilized resource that could serve as a critical bridge between laboratory/preclinical models and successful human clinical trials through a One-Health approach.
RESUMO
The longitudinal quality of life (QoL) of COVID-19 survivors, especially those with post-acute sequelae (PASC) is not well described. We evaluated QoL in our COVID-19 survivor cohort over 6 months using the RAND SF-36 survey. From July 2020-March 2021 we enrolled 110 adults from the United States with a positive SARS-CoV-2 nasopharyngeal polymerase chain reaction (PCR) into the Northern Colorado Coronavirus Biobank (NoCo-COBIO). Demographic data and symptom surveillance were collected from 62 adults. In total, 42% were hospitalized, and 58% were non-hospitalized. The Rand SF-36 consists of 36 questions and 8 scales, and questions are scored 0-100. A lower-scale score indicates a lower QoL. In conclusion, hospitalization, PASC, and disease severity were associated with significantly lower scores on the RAND SF-36 in Physical Functioning, Role Limitation due to Physical Health, Energy/Fatigue, Social Functioning, and General Health. Long-term monitoring of COVID-19 survivors is needed to fully understand the impact of the disease on QoL and could have implications for interventions to alleviate suffering during recovery.
