Thoroughbred Racehorses

Training has a strong effect on the physiology of hematological parameters and blood coagulation, both in humans and in horses. Several blood changes have been reported after exercise in horses but available data differ. We aimed to investigate modifications in complete blood count and some hemostatic parameters induced by the first training period in young untrained Thoroughbred racehorses to detect a possible labile blood coagulability in racehorses. Twenty-nine untrained 2-year-old Thoroughbreds were followed during their incremental 4-month sprint exercise schedule. Blood collection was performed once a month, five times (T-30, T0, T30, T60 and T90), before and during the training period for measurement of complete blood count (CBC) and blood clotting parameters (prothrombin time—PT, activated partial prothrombin time—APTT, thrombin clotting time—TCT, fibrinogen—Fb, thrombin–antithrombin complex—TAT). Differences among the time points for each parameter were analyzed (ANOVA, Kruskal–Wallis one-way analysis of variance, p < 0.05). In Thoroughbreds, the first long-term exercise workout period was found to induce a statistical increase in red blood cell indexes and lymphocytes, eosinophils and platelet counts, as well as a hypercoagulability state evident at 30 days of training, which returned to basal levels after 90 days. Regular physical exercise seems to blunt the negative effects of acute efforts on hematological and clotting parameters, an effect that may be attributed to the training condition.

Thoroughbred Racehorses

Training has a huge effect on physiological homeostasis. The Thoroughbred racehorse is a valid animal model to investigate such changes for training schedule fine-tuning. As happens in human athletes, it is hypothesized that biochemical and immune response changes and related biomolecular variations could be induced by training programs. The aim of this study was to investigate, for the first time, the long-term metabolic and biomolecular modifications in young untrained Thoroughbred racehorses in the first 4-month timeframe training period. Twenty-nine clinically healthy, untrained, two-year-old Thoroughbred racehorses were followed during their incremental 4-month sprint exercise schedule. Blood collection was performed once a month, five times (T-30, T0, T30, T60, and T90). For each sample, lactate concentration, plasma cell volume (PCV), and hematobiochemical parameters (glucose, urea, creatinine, aspartate aminotransferase (AST), γ-glutamyltransferase (GGT), alkaline phosphatase (ALP), total bilirubin (Tbil), lactate dehydrogenase (LDH), creatine kinase (CK), cholesterol, triglycerides, albumin (Alb), total proteins (TPs), phosphorus (P), calcium (Ca2+), magnesium (Mg), sodium (Na+), potassium (K−), and chloride (Cl)) were determined. At T-30 and T90, serum protein electrophoresis (SPE), serum amyloid A (SAA), and real-time qPCR were performed on all samples to evaluate the expression of key genes and cytokines related to inflammatory and Th2 immunity responses: Interleukin-4 (IL-4), Interleukin-6 (IL-6), Interleukin-10 (IL-10), Interleukin-1β (IL-1β), Octamer-Binding Transcription Factor 1 (OCT1), B-cell lymphoma/leukemia 11A (BCL11A). Statistical analysis was performed (ANOVA and t test, p < 0.05). Significant modifications were identified compared with T-30 for PCV, glucose, triglycerides, cholesterol, lactate, urea, creatinine, Tbil, ALP, LDH, Na+, K−, Ca2+, SAA, TPs, SPE, IL-6, IL-4, Oct-1, and BCL11A. In conclusion, the first long-term training period was found to induce fundamental systemic changes in untrained Thoroughbreds.

Objectives The objective of this study was to verify the safety of policosanol supplementation for domestic cats. The effects of raw and encapsulated policosanol were compared with positive (L-carnitine) and negative (no supplementation) controls on outcomes of complete blood count, serum biochemistry, energy expenditure, respiratory quotient and physical activity in healthy young adult cats. Methods The study was a replicated 4 × 4 complete Latin square design. Eight cats (four castrated males, four spayed females; mean age 3.0 ± 1.0 years; mean weight 4.36 ± 1.08 kg; mean body condition score 5.4 ± 1.4) were blocked by sex and body weight then randomized to treatment groups: raw policosanol (10 mg/kg body weight), encapsulated policosanol (50 mg/kg body weight), L-carnitine (200 mg/kg body weight) or no supplementation. Treatments were supplemented to a basal diet for 28 days with a 1-week washout between periods. Food was distributed equally between two offerings to ensure complete supplement consumption (first offering) and measure consumption time (second offering). Blood collection (lipid profile, complete blood count, serum biochemistry) and indirect calorimetry (energy expenditure, respiratory quotient) were conducted at days 0, 14 and 28 of each period. Activity monitors were worn 7 days prior to indirect calorimetry and blood collection. Data were analyzed using a repeated measures mixed model (SAS, v.9.4). Results Food intake and body weight were similar among treatments. There was no effect of treatment on lipid profile, serum biochemistry, activity, energy expenditure or respiratory quotient ( P >0.05); however, time to consume a second meal was greatest in cats fed raw policosanol ( P <0.05). Conclusions and relevance These data suggest that policosanol is safe for feline consumption. Further studies with cats demonstrating cardiometabolic risk factors are warranted to confirm whether policosanol therapy is an efficacious treatment for hyperlipidemia and obesity.

Aim: To establish the reference values of hematological parameters in blood donors of all the four provinces of Pakistan as a general population. Methods: This was a multicenter cross-sectional study conducted from Jan 2017-Oct 2017 in the blood bank and the Dept. of Haematology, The CH&ICH, Lahore, Fatimid Foundation, Karachi, Bolan medical college, Quetta, Armed Forces Institute of Transfusion, Rawalpindi & Ayub medical college, Abbottabad, KPK. Blood samples of 1060 male and female blood donors were collected from the blood banks of all the centers mentioned above. CBC and differential were performed using an automated hematology analyzer in the respective departments. Results: The mean and 95% reference values (2.5th-97.5th) for males WBC 7.752+4.506×109 cells/L, RBC 4.958 +1.331, HB 14.258 +3.423 g/dl, HCT 41.967 +16.345, MCV 84.584 +15.933, PLT 219.485 +197.331, LYM 3.346 +10.112, NEUT 6.843+23.557, MONO 0.811 +3.601, EO 0.327 +0.995. For females WBC 7.174+3.037, RBC4.567 +1.086, HB 12.972 +2.752, HCT39.647 +48.186, PLT 264.07+175.079, LYM 2.537+5.005, NEUT 4.769+11.314, MONO 0.460 +0.909, EO 0.188+0.39 Conclusion: The hematological profile of the population in all four provinces of Pakistan differed from the reports of other countries and the standard reference ranges described in the textbook. So, our own hematological parameters must be followed. More studies must be carried out on other age groups and even on adults to strengthen our results.

ABSTRACT An adult female spayed dog was evaluated after inadvertently receiving a total dose of 1,750 mg oral cyclophosphamide, equivalent to 2,303 mg/m2, over 21 days (days −21 to 0). Nine days after the last dose of cyclophosphamide (day +9), the dog was evaluated at Perth Veterinary Specialists. Physical examination revealed mucosal pallor, a grade 2/6 systolic heart murmur, and severe hemorrhagic cystitis. Severe nonregenerative pancytopenia was detected on hematology. Broad spectrum antibiotics, two fresh whole blood transfusions, granulocyte colony stimulating factor, and tranexamic acid were administered. Five days after presentation (day +14), the peripheral neutrophil count had recovered, and by 12 days (day +21) the complete blood count was near normal. A second episode of thrombocytopenia (day +51) was managed with vincristine, prednisolone, and melatonin. The dog made a complete recovery with no long-term complications at the time of writing. To the author's knowledge, this is the highest inadvertently administered dose of cyclophosphamide to result in complete recovery.

Introduction: numerous biological parameters are physiologically modified during normal pregnancy, in particular hematology. The knowledge of these modifications of the maternal body by biologists and clinicians allows the screening of possible anomalies. In Morocco, the reference values of the complete blood count test for pregnant woman are missing, as are those specific to different trimesters of pregnancy. The aim of this study is to look for the reference values for healthy pregnant women of the Northwest region of Morocco, to compare them to those of non-pregnant women (control) and to those of the literature. Methods: blood samples were taken voluntarily from 3898 healthy pregnant women from 18 to 46 years old who presented themselves at the center of health Kalaa and at the service of gynecology obstetrics of the Provincial Hospital Center of M'diq (Morocco), for prenatal care. To establish the reference intervals of the CBC for non-pregnant women, a control group was constituted by 7035 healthy women from 18 to 50 years old selected according to the Moroccan law of blood donation. The CBC was measured on a Sysmex KX21N® analyzer. For each sample a systematic blood smear was done to determine the leukocyte differential. Results: a statistically significant difference between the pregnant women and control group was noted (p < 0.05) for all the hematological parameters: red blood cells, hematocrit, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, leukocytes, neutrophils, basophils, eosinophils, lymphocytes, monocytes, platelets and mean platelet volume. So, the comparison of the averages established between the first, second and third trimester of pregnancy showed the existence of a significant variation with regard to all the parameters of the CBC test looked for (p < 0.001). Conclusion: the present study provides additional baseline data for basic hematological parameters in healthy pregnant Moroccan women and concluded that pregnancy in women has the tendency to alter some hematological indices. For these reasons, there is an interest to take these modifications into account for optimal maternal and fetal medical care.

Objective This study was aimed to establish local reference values for hematological indices and hemoglobin (Hb) fractions in umbilical cord blood (UCB) for the northern population of Tunisia. Study Design Our study included full-term newborns by vaginal deliveries. Hematological parameters were collected using an automated blood cell counter. The amounts of Hb fractions were measured by capillary electrophoresis of Hb. Statistical analysis was performed using R software. Results A total of 328 cord blood samples were analyzed. Among them, 154 (male: 44.8%, female: 55.2%) were used to establish reference values. The normal reference values of complete blood count (CBC) and Hb fractions were calculated. Mean neonatal Hb was 14.75 ± 2.26 g/dL. Gestational age affects the expression of CBC values as red blood cell (RBC), Hb, hematocrit (Hct), mean corpuscular volume (MCV), white blood cell (WBC), and the Hb profile. Umbilical blood hemogram parameters and Hb profile are affected by the environment; higher in newborns from urban regions but not affected by gender ratio. Conclusion Reference ranges of normal CBC indices and Hb fractions have been successfully established in Tunisian neonates' UCB. Our data suggest reference values that could be useful for neonatal patients' laboratory results and clinical interpretation. Key Points

Background: Alterations in the hematological parameters are thought to have the capacity to act as an adjuvant tool in strengthening the suspicion of malaria, thereby prompting a more meticulous search for malaria parasites.Methods: 186 cases with malaria positive for immunochromatographic test (ICT) malaria presenting with fever ≥101 °F, confirmed on peripheral blood film, of 20-60 years were included. Patients with coagulopathy and bleeding disorders such as hemophilia, brain tumors, tuberculosis meningitis, viral or bacterial encephalitis and multiple sclerosis were excluded. Sample was taken to the laboratory, for routine investigations like ICT malaria and complete blood count (CBC) to diagnose anemia and low platelet count.Results: Patients of 20 to 60 years of age with mean 41.80±8.51. Out of 186 patients, 101 (54.30%) were male and 85 (45.70%) were female with 1:2:1 ratio. Mean duration of disease was 4.91±1.32 days. Frequency of derangement in hematological parameters was anemia in 27 (14.52%) patients and 142 (76.34%) with thrombocytopenia. 127 cases were of Plasmodium vivax and 59 cases were of Plasmodium falciparum. Patients were more anemic as disease period prolonged. Patients infected by Plasmodium vivax showed more tendencies towards anemia and reduction in platelet count as compare to Plasmodium falciparum.Conclusions: The frequency of derangement in hematological parameters i.e. anemia and low platelet count, among malarial patients is quite high and more cases were of Plasmodium vivax and it showed anemia and thrombocytopenia was more pronounced in Plasmodium vivax.

A 15-month-old intact female Pitbull was referred because of recurrent, episodic, self-limiting, excitement-induced bleeding from nontraumatised skin. No abnormalities were detected upon physical examination. Subsequently, the dog went for a walk under the direct supervision of one of the authors, became overexcited and, after approximately five minutes, bloody liquid, with a patchy distribution, appeared along the hair shafts of the face and neck. The affected skin was congested, partially blanching on diascopy and bloody liquid was oozing from the follicular openings. Urticaria, dermographism and hypertension were excluded, the complete blood count and coagulation profile were within the reference ranges and an analysis of the bloody exudate confirmed its blood components. The cutaneous bleeding of the dog followed a self-limited course, with no episodes during the last two years. Clinical and laboratory findings and the long-term evolution of this dog bear striking similarities to haematidrosis, a rare human disease of multifactorial aetiology and equivocal pathogenesis.
