Involvement of veterinary students in the placement of intravenous catheters in adult horses in a teaching hospital does not significantly increase the rate of catheter complications.

OBJECTIVE: To determine whether student involvement in intravenous catheter (IVC) placement increases the risk for complications and to report the rate and types of complications associated with IVCs in adult horses in a university teaching hospital. ANIMALS: 455 IVCs placed in 394 horses. METHODS: Data relevant to IVC placement and removal were retrieved from an electronic medical record search including records of adult horses from January 1 to December 31, 2022. Data retrieved from records included the role of the individual who prepared the site and placed the IVC, site of IVC placement, and type of IVC. The reason for removal of the IVC and presence or absence of detectable changes within the vein at the time of removal were documented in addition to clinical data, allowing for classification of each case. Data were reviewed retrospectively, and statistical analyses were performed using mixed-effects logistic regression models. Significance was set at P ≤ .05. RESULTS: The overall rate of complications was 15.6%, and the most common type of complication was swelling of the vein. Students were involved in 87 of 455 IVC site preparations and placements, and there were no statistically significant differences in complication rates between IVC sites prepared or placed by veterinary students versus nonstudent personnel. CLINICAL RELEVANCE: Veterinary personnel and clients may be hesitant to allow student involvement in IVC placement in horses, but these data suggest that student involvement does not increase the risk of IVC complications.

Persistent long-term habitat use by Florida manatees at Fort Pierce, Florida from 1997 to 2020.

To survive cold winters, Florida manatees (Trichechus manatus latirostris) depend on artificial (i.e., power plants) and natural warm water sources such as springs and passive thermal basins. Passive thermal basins can provide critical habitat for manatees for short or extended periods of time. The Henry D. King Powerplant in Fort Pierce, Florida discharged warm water into Moore's Creek until it went offline in 1995. However, it is unknown to what degree manatees continue to occupy this area and how environmental factors influence their occurrence in the creek. To explore this, we examined the habitat use of Florida manatees in Moore's Creek after the shutdown from November 1997 to March 2020 from daily counts of manatees. In addition, we correlated local environmental data (ambient air, temperature, salinity) to assess if Moore's Creek had properties indicative of a passive thermal basin. Results indicated there was not an increase or decrease in habitat use over twenty years in the Creek. The consistent use of Moore's Creek over the study period suggests that this habitat possesses thermal and freshwater resources to support manatee occurrence long-term. These findings provide robust support for the importance of this habitat and passive thermal basins for Florida manatees.

Identifying delay in glymphatic clearance of labeled protons post-acute head trauma utilizing 3D ASL MRI (arterial spin labeling): a pilot study.

This study correlated mild traumatic brain injury (mTBI) cognitive changes with ASL-MRI glymphatic clearance rates (GCRs) and recovery with GCR improvement. mTBI disrupts the blood brain barrier (BBB), reducing capillary mean transit time and GCRs. mTBI is clinically diagnosed utilizing history/examination findings with no physiologic biomarkers. 3D TGSE (turbo-gradient spin-echo) pulsed arterial spin-labeling 3T MRI with 7 long inversion times (TIs) assessed the signal clearance of labeled protons 2800-4000 ms postlabeling in bifrontal, bitemporal, and biparietal regions within 7 days of mTBI and once clinically cleared to resume activities. The Sport Concussion Assessment Tool Version 5 (SKAT5) and Brief Oculomotor/Vestibular Assessment evaluated injured athletes' cognitive function prior to MRIs. The pilot study demonstrated significant GCRs improvement (95% CI - 0.06 to - 0.03 acute phase; to CI-recovery CI 0.0772 to - 0.0497; P < 0.001 in frontal lobes; and parietal lobes (95% CI - 0.0584 to - 0.0251 acute; CI - 0.0727 to - 0.0392 recovery; P = 0.024) in 9 mTBI athletes (8 female, 1 male). Six age/activity-matched controls (4 females, 2 males) were also compared. mTBI disrupts the BBB, reducing GCR measured using the 3D ASL MRI technique. ASL MRI is a potential noninvasive biomarker of mTBI and subsequent recovery.

Error reporting in a large animal veterinary teaching hospital identifies medication errors occur most often in the prescribing phase of therapy.

OBJECTIVE: To identify the rate at which medication errors occurred over a 2-year period in a large animal veterinary teaching hospital and describe the types of errors that occurred. SAMPLE: 226 medication errors over 6,155 large animal visits occurred during the study period. Multiple errors may have affected the same patient. METHODS: Medication error reports from March 1, 2021, to March 31, 2023, were reviewed retrospectively and classified by species, type of drug, and month and day of the week the error occurred. Errors were categorized according to multiple previously developed systems to allow for comparison to other studies. RESULTS: 226 medication errors occurred over 6,155 patient visits in a 2-year period: 57.5% (130/226) were identified by a dedicated large animal pharmacist, and 64.2% (145/226) of errors were identified and corrected before reaching the patient. Prescription/medication order errors (58.4% [132/226]) occurred significantly more often than errors in medication preparation (21.7% [49/226]; P < .001) and administration (19.6%; P < .001). Antibiotics (48.7% [110/226]) and NSAIDs (17.7% [40/226]) were the drug classes most involved in errors. CLINICAL RELEVANCE: Most medication errors in this study occurred in the ordering/prescribing phase. This is similar to reports in human medicine, where standardized medication error reporting strategies exist. Developing and applying similar strategies in veterinary medicine may improve patient safety and outcome.

A systems approach using Diversity Outbred mice distinguishes the cardiovascular effects and genetics of circulating GDF11 from those of its homolog, myostatin.

Growth differentiation factor 11 (GDF11) is a member of the TGF-ß protein family that has been implicated in the development of cardiac hypertrophy. While some studies have suggested that systemic GDF11 protects against cardiomyocyte enlargement and left ventricular wall thickening, there remains uncertainty about the true impact of GDF11 and whether its purported effects are actually attributable to its homolog myostatin. This study was conducted to resolve the statistical and genetic relationships among GDF11, myostatin, and cardiac hypertrophy in a mouse model of human genetics, the Diversity Outbred (DO) stock. In the DO population, serum GDF11 concentrations positively correlated with cardiomyocyte cross-sectional area, while circulating myostatin levels were negatively correlated with body weight, heart weight, and left ventricular wall thickness and mass. Genetic analyses revealed that serum GDF11 concentrations are modestly heritable (0.23) and identified a suggestive peak on murine chromosome 3 in close proximity to the gene Hey1, a transcriptional repressor. Bioinformatic analyses located putative binding sites for the HEY1 protein upstream of the Gdf11 gene in the mouse and human genomes. In contrast, serum myostatin concentrations were more heritable (0.57) than GDF11 concentrations, and mapping identified a significant locus near the gene FoxO1, which has binding motifs within the promoter regions of human and mouse myostatin genes. Together, these findings more precisely define the independent cardiovascular effects of GDF11 and myostatin, as well as their distinct regulatory pathways. Hey1 is a compelling candidate for the regulation of GDF11 and will be further evaluated in future studies.

Assessing health disparities in foods and beverages served in early care and education programs across Georgia.

BACKGROUND: Obesity disproportionately impacts children who are Black and Hispanic, those who live in rural communities and those who have low income. Predisposition to obesity early in life is profoundly impacted by feeding habits during the preschool years. The early care and education (ECE) setting impacts children's health by providing daily meals. OBJECTIVE: The goal of this study was to identify whether or not health disparities in foods and beverages served in ECE programs in Georgia exist based on socioeconomic, demographic and geographic variables. METHODS: A random sample was drawn from 3054 ECE programs across the state of Georgia. The likelihood of serving specific foods and beverages in ECE programs in the previous day was measured. Percentages and frequencies, logistic regressions, Spearman's rho and Odds ratio tests determined outcomes. RESULTS: A total of 974 surveys were returned. Data were stratified based on the income level of the participant families, race of enrolled children and geographic location of the ECE program. Disparities existed between programs based on race of enrolled children and geographic location. For example, although the odds of providing sweets increased by 0.6% as the percentage of Black children enrolled increased, the provision of healthier foods, such as the odds of providing fruits (P = .001), vegetables (P = .001) and protein (P = .001) also increased. However, after results were adjusted for covariates findings did not remain significant. CONCLUSIONS: Future research focused on evaluating the foods and beverages provided in ECE programs and the relationship of how income, race and location are related may provide further understanding about the disproportionate childhood obesity rates in America.

Fecal Lactoferrin Predicts Primary Nonresponse to Biologic Agents in Inflammatory Bowel Disease.

INTRODUCTION: Fecal lactoferrin (FL) is a timely and accurate marker of inflammation in ulcerative colitis (UC) and Crohn's disease (CD). The aim of this study was to verify whether FL can predict primary nonresponse (PNR) to biologic agents during induction. METHODS: Retrospective outcome review in 27 patients (13 with CD and 14 with UC) tested for baseline FL and retested within a week after the first and second induction doses. Clinical/biochemical outcomes were evaluated at end of induction and at follow-up (3-24 months). RESULTS: Compared to baseline, changes of the Harvey-Bradshaw (CD) and Partial Mayo Scoring (UC) indices at end of induction separated responders (18/27 or 67%) from nonresponders (9/17 or 33%). In all patients, the initial FL value at induction decreased compared to baseline, continuing to decrease after the following dose in clinical responders while bouncing back in the others. Models targeting the 2 consecutively decreased FL values or the second FL value compared to baseline or the second FL value compared to the first were able to accurately predict response at end of induction. Follow-up assessment confirmed clinical remission in initial responders (with FL values reduced on the average by 94 ± 10% compared to baseline). CONCLUSIONS: In CD and UC patients during induction with biologic agents, early FL measurements accurately separate clinical responders from those experiencing PNR. The method described here offers several potential advantages over other strategies to assess and manage these patients.

Beverage Policy Implementation by Child and Adult Care Food Program Participation and Program Type: A Statewide Examination in Georgia.

BACKGROUND: The child care setting is a promising venue to establish healthy habits and promote obesity prevention. One major contributor to weight gain among young children is high intake of sugar-sweetened beverages (SSBs). Increasing access to water and other healthy beverages is a viable strategy to reduce childhood obesity. The goal of our study was to investigate implementation of the beverage policies in child care programs in Georgia (GA) by Child and Adult Care Food Program (CACFP) participation and program type. METHODS: The study employed a cross-sectional design. A statewide survey was conducted using the GA Child Care Wellness Survey. A random sample of 3054 child care programs was obtained. Programs were stratified by six state regions to acquire a representative sample. RESULTS: A total of 974 surveys were returned. Sixty-seven percent of the respondents were enrolled in CACFP. Programs participating in CACFP (96%) were less likely to serve SSBs (x2(2) = 15.309, p < 0.001), than non-CACFP programs (90%). CACFP programs were more likely to serve low-fat or fat-free milk to 2-5-year olds than non-CACFP programs (87% vs. 35%, p < 0.001). Family child care homes were significantly more likely to comply with serving only whole milk to 1 year olds (66%; p < 0.001) than other program types. All program types had low compliance with implementing water policies. CONCLUSIONS: Study outcomes provide vital information on the implementation of beverage policies that can inform beverage policy training, with the ultimate goal of reducing obesity risk and promoting healthier diets among preschool children in GA.

Fecal lactoferrin accurately reflects mucosal inflammation in inflammatory bowel disease.

BACKGROUND: Studies have demonstrated a potential role for fecal biomarkers such as fecal calprotectin (FC) and fecal lactoferrin (FL) in monitoring inflammatory bowel diseases (IBD) - Crohn's disease (CD) and ulcerative colitis (UC). However, their correlation to endoscopic scores, disease severity and affected intestinal surface has not been extensively investigated. AIM: To correlate FL, and for comparison white blood cell (WBC) and C-reactive protein (CRP), with endoscopic scores, disease extent and location in CD and UC. METHODS: Retrospective analysis in 188 patients who had FL, CRP and WBC determined within 30 d of endoscopy. Disease location, disease extent (number of intestinal segments involved), disease severity (determined by endoscopic scores), timing of FL testing in relation to colonoscopy, as well as the use of effective fast acting medications (steroids and biologics) between colonoscopy and FL measurement, were recorded. RESULTS: In 131 CD and 57 UC patients, both CRP and FL - but not WBC - distinguished disease severity (inactive, mild, moderate, severe). In patients receiving fast-acting (steroids or biologics) treatment in between FL and colonoscopy, FL showed a higher correlation to endoscopic scores when tested before vs after the procedure (r = 0.596, P < 0.001, vs r = 0.285, P = 0.15 for the Simple Endoscopic Score for CD; and r = 0.402, P = 0.01 vs r = 0.054 P = 0.84 for Disease Activity Index). Finally, FL was significantly correlated with the diseased mucosal surface (colon-ileocolon > small bowel) and the number of inflamed colon segments. CONCLUSION: FL and CRP separated disease severity categories with FL showing lower discriminating P-values. FL showed a close correlation with the involved mucosal surface and with disease extent and was more closely correlated to endoscopy when determined before the procedure - this indicating that inflammatory activity changes associated with therapy might be rapidly reflected by FL levels. FL can accurately and timely characterize intestinal inflammation in IBD.

Brief mindfulness meditation group training in aphasia: exploring attention, language and psychophysiological outcomes.

BACKGROUND: Stroke is currently the leading cause of long-term disability in adults in the United States. There is a need for accessible, low-cost treatments of stroke-related disabilities such as aphasia. AIMS: To explore an intervention for aphasia utilizing mindfulness meditation (MM). This preliminary study examines the feasibility of teaching MM to individuals with aphasia. Since physiological measures have not been collected for those with aphasia, the study was also an exploration of the potential attention, language and physiological changes after MM in adults with aphasia during a brief, daily group training. METHODS & PROCEDURES: A 5-day MM group training was provided to adults with aphasia (n = 5) with a waitlist control group (n = (3) who engaged in 'mind wandering'. Participants were assigned to groups in a pseudo-random manner. A double baseline (2 days apart) was administered prior to the training and/or control group beginning. Both the training and the control groups met in a group setting. Salivary cortisol, heart rate and heart rate variability were measured during each day for both groups. Measures of attention, auditory comprehension and fluency were collected immediately after the study period and 1 week post-completion. OUTCOME & RESULTS: This study reinforces findings from previous work indicating that adults with aphasia can learn MM. Although not statistically significant, the training group demonstrated improved fluency immediately after MM; however, changes were not maintained at follow-up. Physiological measures showed little effect associated with MM training. No changes in attention were observed for either group. CONCLUSION & IMPLICATIONS: This is an emerging area of interest due to the potential low cost of MM training. Furthermore, MM is easily taught to patients, suggesting the possibility for widespread use in clinical practice as a supplement to existing language-focused interventions.

A Bayesian Approach to Age-at-Death Estimation from Osteoarthritis of the Shoulder in Modern North Americans.

Osteoarthritis (OA) is a marker of degeneration within the skeleton, frequently associated with age. This study quantifies the correlation between OA and age-at-death and investigates the utility of shoulder OA as a forensic age indicator using a modern North American sample of 206 individuals. Lipping, surface porosity, osteophyte formation, eburnation, and percentage of joint surface affected were recorded on an ordinal scale and summed to create composite scores that were assigned a specific phase. Spearman's correlation indicated a positive relationship between each composite score and age (right shoulder = 0.752; left shoulder = 0.734). Transition analysis revealed a tendency toward earlier degeneration of the right shoulder. Bayesian statistics generated phase-related age estimates based on highest posterior density regions. Best age estimates were into the seventh decade at the 90th and 50th percentile. The proposed method supplements traditional techniques by providing age estimates beyond a homogenous 50+ age cohort.
