Associations between health, productive performance and oral fluid biomarkers in commercial pig farms.

Background: Oral fluid contains analytes that may be reflective of health and welfare in pig herds. Additionally, oral fluid collection is a more convenient and cost-effective option when compared to blood sampling, increasing the potential of oral fluid as a non-invasive alternative tool. While a growing number of biomarkers can be measured in porcine oral fluid, the use of these analytes to compare commercial herds in veterinary practice is still limited.

Saliva as a Potential Source of Biomarkers in Cows with Metritis: A Pilot Study.

Metritis affects 5-20% of cows after parturition, negatively impacting animal welfare and the profitability of dairy farms, increasing culling rates and costs, and decreasing productivity and reproduction rates. This study compared the results of a comprehensive biochemical panel consisting of 25 salivary and 31 serum analytes between healthy cows ( = 16) and cows with metritis ( = 12). Descriptive parameters such as depression, rectal temperature, body condition score (BCS), heart rate, respiratory rate, mucous color, ruminal motility, vaginal discharge, milk production, and complete hematology analyses were also assessed for comparative purposes.

Salivary biomarkers as pioneering indicators for diagnosis and severity stratification of pediatric long COVID.

Introduction: Long COVID, or post-acute sequelae of SARS-CoV-2 infection (PASC), manifests as persistent and often debilitating symptoms enduring well beyond the initial COVID-19 infection. This disease is especially worrying in children since it can seriously alter their development. Presently, a specific diagnostic test or definitive biomarker set for confirming long COVID is lacking, relying instead on the protracted presence of symptoms post-acute infection.

Evaluation of the presence of gingivitis as confounding factor in assessing inflammatory status in serum and saliva of dogs with diabetes mellitus.

The aim of this study was to evaluate the changes in the serum and salivary inflammatory markers induced by Diabetes mellitus (DM) in dogs and to assess the possible confounding effect of gingivitis. A panel of 13 cytokines was measured in the serum and saliva of dogs diagnosed with DM and compared with healthy dogs without gingivitis (control group 1; CG1) and dogs with gingivitis but otherwise healthy (control group 2; CG2). The results of the present study showed statistically significantly higher levels of IL-8, KC-like and MCP1 in the serum of dogs with DM compared to CG1 dogs.

Serum Ferritin in Obese Dogs: Changes and Comparison with Other Analytes.

Canine obesity is the most common nutritional disorder and is associated with decreased quality of life and longevity as well as comorbidities including cardiorespiratory, endocrine, oncologic, or orthopaedic disorders. Ferritin is a major acute-phase protein in dogs, increasing during inflammation; however, it could also be affected by other conditions, including trauma, iron metabolism dysregulations, neoplasia, or hypoxia. Higher ferritin levels have been reported in obese humans, but ferritin has not been explored in canine obesity.

Acute Phase Proteins in Dogs with Natural Infection by .

Acute phase proteins have been used as tools for the diagnosis, monitoring, and prognosis of several diseases in domestic animals. However, the dynamics of these proteins in infection by , the causative agent of Chagas disease in dogs, is still unknown. The aim of this study was to determine concentrations of acute phase proteins (C-reactive protein, haptoglobin, ferritin and paraoxonase-1) in dogs in a coastal town of Ecuador, with natural infection with or without seroreactivity of , , , , and .

Risk factors associated with Streptococcus suis cases on pig farms in Spain.

Background: Streptococcus suis can cause meningitis, polyarthritis and acute death in piglets. However, the risk factors associated with S. suis infection remain incompletely understood.

Effects of filtration and alpha-amylase depletion on salivary biochemical composition measurements.

The effects of filtration (F) and alpha-amylase depletion (AD) were assessed in n = 34 saliva samples. Each saliva sample was split into three aliquots and treated as follows: (1) no treatment; (2) 0.45μm commercial filter; and (3) 0.

Range Restriction Affects Factor Analysis: Normality, Estimation, Fit, Loadings, and Reliability.

A sample suffers range restriction (RR) when its variance is reduced comparing with its population variance and, in turn, it fails representing such population. If the RR occurs over the latent factor, not directly over the observed variable, the researcher deals with an indirect RR, common when using convenience samples. This work explores how this problem affects different outputs of the factor analysis: multivariate normality (MVN), estimation process, goodness-of-fit, recovery of factor loadings, and reliability.

Effectiveness and Safety of High-Dose Thromboprophylaxis in Morbidly Obese Major Trauma Patients.

Background: Trauma increases risk for venous thromboembolism (VTE) and obesity is a known independent risk factor for VTE development. Currently, no consensus on an optimal prophylactic dosing strategy for morbidly obese trauma patients exists. The objective of this study is to evaluate the effectiveness and safety of a BMI-stratified dosing strategy for VTE prophylaxis in morbidly obese trauma patients.

Hemostatic Efficacy and Safety of 4-Factor Prothrombin Complex Concentrate in Doac-Associated Intracranial Hemorrhage.

Factor Xa (FXa) inhibitor use has increased over the last decade and though associated rates of major bleeding are lower compared to warfarin, outcomes from intracranial hemorrhage (ICH) are still significant. Targeted FXa inhibitor reversal agent became available in 2018, however use of 4-factor prothrombin complex concentrate (4F-PCC) for FXa inhibitor-associated ICH continues at many institutions. Evaluate the safety and hemostatic efficacy of 4F-PCC for FXa inhibitor-associated ICH.

Capnography in newborns under mechanical ventilation and its relationship with the measurement of CO in blood samples.

Introduction: Monitoring the partial pressure of CO (PCO) in newborns who require ventilation would allow avoiding hypocapnia and hypercapnia. The measurement of end-tidal carbon dioxide (ETCO) is an alternative rarely implemented in this population.

Objective: To evaluate the relationship between ETCO and PCO in newborns.

Impact of ASFV Detergent Inactivation on Biomarkers in Serum and Saliva Samples.

African swine fever (ASF) is a notifiable viral disease of domestic and wild suids. Despite intensive research efforts, the pathogenesis of the disease is still far from being understood. Analysis of biomarkers in different body fluids may supplement traditional pathogenesis studies.

Biomarkers of sepsis in pigs, horses and cattle: from acute phase proteins to procalcitonin.
