One horse was treated with ammonium tetrathiomolybdate. Two horses had several recurring episodes over the course of several months, an uncommon presentation in ruminants suffering from copper toxicity. Excess copper was associated with soil fertilization with poultry litter or treatment of previous or neighbor crops with copper-containing products. It can be concluded that copper toxicity does occur in horses and may arise from several sources and/or be associated with predisposing dietary factors. Given the growing number of cases, the condition should be included in the differential diagnosis list and proper preventive dietary and pasture fertilization measures adopted.The aim of the present study is to evaluate the correlation between the total protein measured by an optical refractometer and the concentration of IgG by radial immunodiffusion (RID) to determine the performance of the optical refractometer to diagnose the failure of passive transfer of immunity (FPTI) in 12-hour-old foals. Blood was collected from foals (n = 30) 12 hours after birth. A study was carried out to measure the serum IgG concentration by RID test and measure total protein (TP) by optical refractometer. The correlation coefficient was measured between the TP concentration and the IgG-RID. Correlation was made between the IgG-IDR levels of colostrum in mares and the IgG-IDR concentration of the plasma of the foals. A ROC curve was made to identify the ideal cutoff point, in addition to the tests for sensitivity and specificity. The area under the curve (AUC) was calculated. The IgG concentration by RID was positively correlated with a refractometer. Colostrum IgG concentration by RID was moderately correlated with foal plasma IgG-RID concentration. In the ROC curve, AUC was 0.931, and the cutoff point found was ≤5,7 g/dL as the most optimal combination, with 100% sensitivity and 73.3% specificity. Thus, it can be concluded that the total protein concentration by refractometer shows effective utility in the evaluation of FPTI in foals since they are highly sensitive, associated with a low cost, easy to handle, and easily carried out in the field.A 1.8-year-old maiden Thoroughbred filly, without previous history of mating or reproductive management, was referred for clinical inspection due to the presence of sanguineous vaginal discharge and severe abdominal pain. Transrectal palpation indicated uterine asymmetry, and transrectal ultrasonography revealed a mass near the cervix measuring 8.3 cm in diameter, with heterogeneous echogenicity, a trabeculated center, and a well-defined hyperechoic border. Smaller masses surrounded the larger uterine mass. During the examination, the mare expelled a uterine mass through the vulva. Histological and immunohistochemical (CD31 and Factor VIII) examinations of the expelled mass suggested a diagnosis of hemangiosarcoma. Therefore, a therapeutic hysterectomy was performed, and examinations of the uterine tissue confirmed the diagnosis. However, the mare was euthanized 2 weeks later due to postoperative complications. The animal was subjected to necropsy, and intestinal adhesions in the surgical incision were diagnosed as postoperative complications. No other neoplasms were found during necropsy, establishing the primary origin of the tumor. This case study presents the first known report of uterine hemangiosarcoma in an equine species.The TCO2 (total carbon dioxide) test is performed on the blood of racehorses as a means of combatting the practice of administering alkalizing agents for the purpose of enhancing performance. Oleic mw The purposes of this review are to present an overview of the factors contributing to TCO2 and to review the literature regarding TCO2 in adult Standardbred and Thoroughbred horses to demonstrate the range of variability of TCO2 in horses. Most of the research published on the topic of TCO2 or bicarbonate measurement in racehorses was accessed and reviewed. PubMed and Google Scholar were the primary search engines used to source the relevant literature. The main physicochemical factors that contribute to changes in TCO2 in horses at rest are changes in strong ions concentration, followed by changes in weak acid (i.e. plasma albumin) concentrations. There is a wide normal distribution of TCO2 in horses ranging from 23 mmol/L to 38 mmol/L. Independent of administration of alkalizing agents, blood TCO2 is affected mainly by feeding, time of day (diurnal variation), season and exercise. There are few studies that have reported hour-by-hour changes in TCO2. Racehorse population studies suffer from lack of validation regarding whether or not a horse was administered an alkalizing agent. It is concluded that the normal range of TCO2 in non-alkalized Standardbred and Thoroughbred horses is significantly wider than has been appreciated, that periods of elevated TCO2 appear to be normal for many horses at rest, and that a TCO2 test alone is not definitive for the purposes of determining of an alkalizing agent has been administered to a horse.Researchers believe that the development and prevalence of abnormal behaviors in horses may be caused by several environmental and biological factors, and the literature offers numerous reports that discuss the causes and effects of stereotypies in these animals. In this light, this study aimed to conduct a systematic review and meta-analysis of the scientific literature, summarizing the main risk factors associated with the development of abnormal behaviors in horses. The searches were conducted over the course of four years in Portuguese, Spanish, and English. The publications reviewed were full text research thesis or articles that addressed issues within the following criteria (1) presentation of epidemiological information on the studied population; (2) prevalence of abnormal behaviors in equine populations; (3) factors associated with the development or prevalence of stereotypies. Data were extracted from each study and inserted into an Excel spreadsheet to be analyzed through descriptive statistics. In addition, the Mann-Whitney U test was used to verify the existence of significant differences between the methodologies (direct observation/questionnaires). The dataset was also analyzed through data mining to identify the main factors that influence the prevalence of abnormal behaviors in the studied population. The results showed a great variation in the mean prevalence of abnormal behaviors, with no significant difference between research conducted through questionnaires or direct observation, and the data mining technique identified that incorrect nutritional management may be the main factor influencing the development and prevalence of abnormal behaviors in horses.Different approaches have been used to improve conception rates at foal heat. Omega-3 fatty acids family and derivatives have improved reproductive efficiency in ruminants, but literature lacks studies evaluating these components on equines. The objective of this study was to evaluate effects of mare dietary supplementation with microalgae rich in docosahexaenoic acid (DHA) during peripartum on follicular dynamics and uterine involution in early post-partum. Eighteen pregnant mares, no particular breed, 410 ± 39.5 kg body weight (BW), and 7.83 ± 2.01 yr old were used. Mares were randomly assigned to control (CONT) or supplementation with microalgae rich in DHA at 0.06 g/kg BW (ALG). Treatments were supplied from 90 d prior to expected foaling date until 7 d after first ovulation. Reproductive evaluations were performed during early post-partum until 7 d after first ovulation through rectal palpation and ultrasonography of the following parameters uterine and endometrium diameters, intrauterine fluid (IUF), uterine echogenicity, uterus tone, and follicular dynamics. Endometrial cells samples were collected to assess mRNA expression of CRP, IL-1β and AKR1C4, using RT-qPCR. Data were analyzed by mixed procedure of SAS. ALG mares had smaller uterine horns diameters and greater uterine echogenicity during post-partum in comparison with CONT. No treatment effects were detected for other characteristics evaluated, but a day effect was observed for uterine and endometrium diameter, IUF, uterine echogenicity, and transcript abundance of endometrial AKR1C4. Supplementation with DHA during peripartum may benefit uterine involution process and odds of early conception, but more studies should be performed regarding fertility.The COVID-19 pandemic has raised concerns around public health (PH) investments. Among OECD countries, Canada devotes one of the largest shares of total health expenditures to PH. Examining retrospectively PH spending growth over a very long period may hold lessons on how to reach this high share. Further, different historical periods can be used to understand how macroeconomic conditions affect PH spending growth. Using forty-three years of data, we examine real PH spending growth per capita, comparatively between thirteen Canadian jurisdictions and with other key publicly funded healthcare sectors (physicians, hospitals, and pharmaceuticals), as well as by four periods defined by macroeconomic conditions. We find a five-fold increase on average in PH spending since 1975, a growth above physicians and hospitals, but below pharmaceuticals. However, there is substantial variation in PH growth between periods and across the country. Because concerns have been raised over PH spending data in other OECD countries, we explore differences between spending estimates reported by the national agency and ten provincial budgetary estimates, and find the former is larger. The magnitude of the difference varies between jurisdictions but not much over time. Although these differences do not challenge the presence of growth in PH spending, they show that the growth may be below that of hospitals. A better categorization of PH financing data is warranted.This study considers the confidence of dental core trainees (DCTs) as they mature and progress through their first six months in an oral and maxillofacial surgery (OMFS) training post. Trainees have different incentives for embarking on a year in OMFS to develop additional skills before settling into general dental practice; as a step towards specialty training; and to help decide about their career direction. Traditionally, an OMFS year has been associated with creating well-rounded and confident clinicians. We surveyed 123 DCTs at three stages over a six-month period to monitor their confidence in 10 clinical domains assessing dentofacial infection, mandibular fractures, midface fractures, intraoral/extraoral swellings, airway risks, intraoral/extraoral lesions (benign/malignant), CT/MRI scans, and performing intraoral/extraoral suturing. The study demonstrates an increase in trainee confidence across all domains over the first six months of an OMFS post, with a particularly significant increase in the assessment of dentofacial infection, mandibular/midface fracture, and both intraoral and extraoral lesions and swellings.
Stress from negative life events may be an important risk factor for chronic cardiometabolic conditions, which are increasingly prevalent among young adults. Support from personal networks is known to buffer stress from negative life events. Yet, evidence for these relationships among both young and older adults remains unclear.
Longitudinal data came from the University of California, Berkeley Social Networks Study (2015-2018), which followed young (aged 21-30 years) and late middle-aged (aged 50-70 years) adults over 4 years. Weighted hybrid fixed and random effects models (completed in 2020) were used to examine the causal relationships among 4 negative life events, distinct forms of network support (e.g., social companionship, emergency help), and self-reported chronic cardiometabolic disease outcomes (i.e., hypertension, diabetes, or a heart condition).
Among young adults, both the death of a close tie (average marginal effect=0.10, p<0.001) and financial difficulties (average marginal effect=0.
