Is There a Difference in the Prevalence of Gastric Ulcers between Stallions Used for Breeding and Those Not Used for Breeding?

Equine gastric ulcer syndrome (EGUS) is a worldwide disease, and includes two different syndromes, Equine Squamous Gastric Disease (ESGD), affecting the squamous mucosa, and Equine Glandular Gastric Disease (EGGD), affecting the glandular mucosa. These two diseases are present in different categories (different activities, ages, etc.) and breeds of horses. The effect of sex on gastric health is not clear: some studies found a higher prevalence of ESGD in geldings and stallions, while others found no influence of sex on the squamous mucosa. The few studies conducted on glandular diseases failed to identify sex as a risk factor. The only study on breeding horses, focused on Thoroughbred mares at pasture, found that 70% of them were affected by gastric ulcerations especially in the squamous mucosa. The aim of this study was to determine the prevalence of EGUS, ESGD, and EGGD in intact males while also investigating the potential influences of breeding and exercise activity on the occurrence and severity of the diseases. A total of 101 intact males were admitted for gastroscopic examination. Comprehensive data regarding their breeding and sports history, management, and presence of clinical signs were recorded. A statistical analysis was performed. Within this equine population, no discernible relationship was found between breeding activity and occurrence and severity of ESGD or EGGD. Exercise and a combination of exercise and breeding activities were found to be associated with the occurrence of EGGD. The presence of clinical signs was correlated only with the grade of ESGD in this cohort of horses.

Evaluation of a smartphone electrocardiograph in healthy foals and comparison to standard base-apex electrocardiography.

Smartphone-based technology for ECG recording has recently spread as a complementary tool for electrocardiographic screening and monitoring in adult horses and in other animal species. The present study aimed to assess the feasibility and accuracy of a smartphone-based ECG in healthy foals. This was a prospective observational study (authorization n. 45,865/2016) including 22 foals aged less than 21 days. A reference standard base-apex ECG (rECG) was acquired, and a smartphone ECG (sECG) was recorded immediately after by using a smartphone-based single lead electrocardiograph. All ECG tracings were evaluated in a blind fashion by a single board-certified cardiologist, who judged whether the tracings were acceptable for interpretation and performed ECG measurements and diagnosis. The Spearman correlation coefficient, the Cohen's k test and the Bland-Altman test were used to assess the agreement between sECG and rECG. All sECG tracings were acceptable for interpretation. All foals showed sinus rhythm on both rRCG and sECG tracings, with perfect agreement in heart rate classification (κ = 0.87; p < 0.001). No clinically relevant differences were found in the assessment of waves and intervals duration. Concerning P wave and QRS complex polarity, the percentage of agreement between rECG and sECG was 78% and 83%, respectively. About ECG tracing quality, rECG and sECG showed a substantial agreement (κ = 0.624; p < 0.001). In conclusion, the smartphone-based ECG device tested in the present study recorded good quality single-lead ECG tracings in foals, reliable for heart rate and ECG measurements, but different polarity of P waves and QRS complexes was found in some foals in comparison to rECG.

Hematology and clinical chemistry in mule foals from birth to two months of age: A preliminary study.

In horses and donkeys, age-related changes in hematological and biochemical parameters preclude the use of normal values of adults in the evaluation of foals. This study aimed to obtain data on hematological and biochemical parameters of mule foals from birth up to the second month of life and to assess age-related changes in order to determine if dedicated reference ranges are required in younger animals. Blood samples from seven healthy mule foals were obtained at birth before colostrum consumption, 24 h, 48 h of life, and then weekly until the second month of life. Results were expressed as mean and standard deviation or median, minimum, and maximum values if showing non-gaussian distribution. Kruskal-Walls and Dunn tests were used to verify the differences among sampling times. Significance was set at P < 0.05. Red blood cell count, packed cell volume and hemoglobin decreased from 24 h to one week of age. Mean corpuscular volume and mean corpuscular hemoglobin decreased over the first month. White blood cells increased from birth to seven days of life. Aspartate amino transferase increased while alkaline phosphatase decreased in the first week of life. Urea, creatinine, and lactate decreased, while glucose concentrations increased at 24 h. Ionized calcium and magnesium and total sodium and potassium showed no changes. In mule foals, several laboratory parameters may be the same or intermediate, lower or higher than in equine or donkey foals, but also compared to all other adult species. The preliminary results suggest that for mule foals, age influences hematological and biochemical parameters.

Apgar Score, Clinical, Hemato-Biochemical, and Venous Blood Gas Parameters in a Cohort of Newborn Mule Foals: Preliminary Data.

The study aimed to assess Apgar scores and collect data on clinical, hemato-biochemical, and venous blood gas parameters in seven mules during their first 48 hours of life. Apgar scores, heart rate (HR), respiratory rate (RR), body temperature (BT), body weight (BW), time to achieve sternal recumbency, stand, nurse, and pass meconium were recorded. Blood samples were collected at birth (T0), 6 (T6), 12 (T12), 24 (T24), 48 (T48) hours of life. Data distribution was verified and differences in laboratory parameters over time assessed. One foal had an Apgar score of 6/8, thus excluded from the statistical analysis. Three foals had an Apgar score of 7/8, three had a score of 8/8. All foals showed suckling reflex within 20 minutes and raised the head within 1 minute; six foals reached sternal recumbency within 2 minutes. Times to stand and nurse were 38.7 ± 13.4 and 72.3 ± 30.5 minutes, respectively. Five foals passed meconium spontaneously in 416.3 ± 401.8 minutes. The mean HR, RR, and BT values were 92 ± 16.1 bpm, 50.2 ± 5.9 bpm, and 37.6 ± 0.3°C, respectively. Creatinine and lactate decreased from birth to 48 hours. Blood glucose increased from 12 hours. Mg increased from 12 to 24 hours. Compared to horses and donkeys, mules showed an intermediate BW, shorter time to stand and nurse, longer time to pass meconium, intermediate HR and lower RR. Compared to donkey mules showed lower BT. Other dissimilarities from the parental species were found in laboratory parameters. Our findings emphasize the need for reference ranges for a comprehensive evaluation of newborn mules.

Independent Predictors of Mortality in Torso Trauma Injuries.

Noncompressible torso injuries (NCTIs) represent a trauma-related condition with high lethality. This study's aim was to identify potential prediction factors of mortality in this group of trauma patients at a Level 1 trauma center in Italy. MATERIALS AND METHODS: A total of 777 patients who had sustained a noncompressible torso injury (NCTI) and were admitted to the Niguarda Trauma Center in Milan from 2010 to 2019 were included. Of these, 166 patients with a systolic blood pressure (SBP) <90 mmHg were considered to have a noncompressible torso hemorrhage (NCTH). Demographic data, mechanism of trauma, pre-hospital and in-hospital clinical conditions, diagnostic/therapeutic procedures, and survival outcome were retrospectively recorded. RESULTS: Among the 777 patients, 69% were male and 90.2% sustained a blunt trauma with a median age of 43 years. The comparison between survivors and non-survivors pointed out a significantly lower pre-hospital Glasgow coma scale (GCS) and SBP (p < 0.001) in the latter group. The multivariate backward regression model identified age, pre-hospital GCS and injury severity score (ISS) (p < 0.001), pre-hospital SBP (p = 0.03), emergency department SBP (p = 0.039), performance of torso contrast enhanced computed tomography (CeCT) (p = 0.029), and base excess (BE) (p = 0.008) as independent predictors of mortality. CONCLUSIONS: Torso trauma patients who were hemodynamically unstable in both pre- and in-hospital phases with impaired GCS and BE had a greater risk of death. The detection of independent predictors of mortality allows for the timely identification of a subgroup of patients whose chances of survival are reduced.

Motorcycle-related trauma:effects of age and site of injuries on mortality. A single-center, retrospective study.

BACKGROUND: Motorcyclists are often victims of road traffic incidents. Though elderly patients seem to have worse survival outcomes and sustain more severe injuries than younger patients, concordance in the literature for this does not exist. The aim of the study is to evaluate the impact of age and injury severity on the mortality of patients undergoing motorcycle trauma. METHODS: Data of 1725 patients consecutively admitted to our Trauma Center were selected from 2002 to 2016 and retrospectively analyzed. The sample was divided into three age groups: ≤ 17 years, 18-54 years, and ≥ 55 years. Mortality rates were analyzed for the overall population and patients with Injury Severity Score (ISS) ≥ 25. Differences in survival among age groups were evaluated with log-rank test, and multivariate logistic regression models were created to identify independent predictors of mortality. RESULTS: A lower survival rate was detected in patients older than 55 years (83.6% vs 94.7%, p = 0.049) and in those sustaining critical injuries (ISS ≥ 25, 61% vs 83%, p = 0.021). Age (p = 0.027, OR 1.03), ISS (p < 0.001, OR 1.09), and Revised Trauma Score (RTS) (p < 0.001, OR 0.47) resulted as independent predictors of death. Multivariate analysis identified head (p < 0.001, OR 2.04), chest (p < 0.001, OR 1.54), abdominal (p < 0.001, OR 1.37), and pelvic (p = 0.014, OR 1.26) injuries as independent risk factors related to mortality as well. Compared to the theoretical probability of survival, patients of all age groups showed a survival advantage when managed at a level I trauma center. CONCLUSIONS: We detected anatomical injury distributions and mortality rates among three age groups. Patients aging more than 55 years had an increased risk of death, with a prevalence of severe chest injuries, while younger patients sustained more severe head trauma. Age represented an independent predictor of death. Management of these patients at a level I trauma center may lead to improved outcomes.

Orthopedic injuries in patients with multiple injuries: Results of the 11th trauma update international consensus conference Milan, December 11, 2017.

BACKGROUND: In blunt trauma, orthopedic injuries are often associated with cerebral and torso injuries. The optimal timing for definitive care is a concern. The aim of the study was to develop evidence-based guidelines for damage-control orthopedic (DCO) and early total care (ETC) of pelvic and long-bone fractures, closed or open, and mangled extremities in adult trauma patients with and without associated injuries. METHODS: The literature since 2000 to 2016 was systematically screened according to Preferred Reporting Items for Systematic Reviews and meta-analyses protocol. One hundred twenty-four articles were reviewed by a panel of experts to assign grade of recommendation and level of evidence using the Grading of recommendations Assessment, Development, and Evaluation system, and an International Consensus Conference, endorsed by several scientific societies was held. RESULTS: The choice between DCO and ETC depends on the patient's physiology, as well as associated injuries. In hemodynamically unstable pelvic fracture patient, extraperitoneal pelvic packing, angioembolization, external fixation, C-clamp, and resuscitative endovascular balloon occlusion of the aorta are not mutually exclusive. Definitive reconstruction should be deferred until recovery of physiological stability. In long bone fractures, DCO is performed by external fixation, while ETC should be preferred in fully resuscitated patients because of better outcomes. In open fractures early debridement within 24 hours should be recommended and early closure of most grade I, II, IIIa performed. In mangled extremities, limb salvage should be considered for non-life-threatening injuries, mostly of upper limb. CONCLUSION: Orthopedic priorities may be: to save a life: control hemorrhage by stabilizing the pelvis and femur fractures; to save a limb: treat soft tissue and vascular injuries associated with fractures, stabilize fractures, recognize, and prevent compartmental syndrome; to save functionality: treat dislocations, articular fractures, distal fractures. While DCO is the best initial treatment to reduce surgical load, ETC should be applied in stable or stabilized patients to accelerate the recovery of normal functions. LEVEL OF EVIDENCE: Systematic review of predominantly level II studies, level II.

A systematic review on the use of topical hemostats in trauma and emergency surgery.

BACKGROUND: A wide variety of hemostats are available as adjunctive measures to improve hemostasis during surgical procedures if residual bleeding persists despite correct application of conventional methods for hemorrhage control. Some are considered active agents, since they contain fibrinogen and thrombin and actively participate at the end of the coagulation cascade to form a fibrin clot, whereas others to be effective require an intact coagulation system. The aim of this study is to provide an evidence-based approach to correctly select the available agents to help physicians to use the most appropriate hemostat according to the clinical setting, surgical problem and patient's coagulation status. METHODS: The literature from 2000 to 2016 was systematically screened according to PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-Analyses] protocol. Sixty-six articles were reviewed by a panel of experts to assign grade of recommendation (GoR) and level of evidence (LoE) using the GRADE [Grading of Recommendations Assessment, Development and Evaluation] system, and a national meeting was held. RESULTS: Fibrin adhesives, in liquid form (fibrin glues) or with stiff collagen fleece (fibrin patch) are effective in the presence of spontaneous or drug-induced coagulation disorders. Mechanical hemostats should be preferred in patients who have an intact coagulation system. Sealants are effective, irrespective of patient's coagulation status, to improve control of residual oozing. Hemostatic dressings represent a valuable option in case of external hemorrhage at junctional sites or when tourniquets are impractical or ineffective. CONCLUSIONS: Local hemostatic agents are dissimilar products with different indications. A knowledge of the properties of each single agent should be in the armamentarium of acute care surgeons in order to select the appropriate product in different clinical conditions.
