Coagulation Pathway

Hirudin, an extract from the leech, has powerful antithrombin activity affecting the blood coagulation pathway. We evaluated the usefulness of hirudin in anticoagulating specimens for routine laboratory tests. Results using blood anticoagulated with hirudin corresponded well with results with blood treated with ethylenediamine tetraacetic acid (EDTA) in the complete blood count (CBC), including white blood cell (WBC) differential count and morphology of blood cells, when CBC was performed within 2 h of blood collection. Clinical chemistry results from hirudin-treated samples were similar to results obtained with serum specimens. Thus, hirudin may be a useful anticoagulant for emergency laboratory medicine.

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.

Objective. To determine primary-care pediatricians' management of febrile infants and compare them with published practice guidelines. Design. Case scenarios were sent to 194 primary-care pediatricians in Utah, describing three febrile infants, ages 21 days, 60 days, and 20 months, corresponding to the three age groups: 0 to 28 days; 29 to 90 days, and 91 days to 36 months for which the guidelines suggest different strategies. Results. Ninety-four pediatricians responded (response rate, 48%). Compliance with the guidelines was 39% for the 21 day old, 9.6% for the 60 day old, and 75% for the 20 month old. No respondent followed the guidelines for all three infants. Performance of tests to determine if an infant was low risk varied from 3%, for a stool white cell examination in a febrile 2 month old with diarrhea, to 75% for a complete blood count in a 20 month old with a temperature of 40°C. Compliance did not differ between private and academic practitioners. Those in practice less than 5 years (n = 22) were more likely than those with more experience to follow the guidelines for the 21 day old but not the other two infants. Conclusion. Primary-care pediatricians in Utah manage febrile infants with fewer laboratory tests and less hospitalization than recent practice guidelines developed by an expert panel of academic specialists suggest.

Febrile Condition

150 febrile patients included children (50), adult (50) and neonates (50) from outpatient departments and inpatients of private clinics and hospitals. Patients presented with fever and chills for more than 1 day to 3 days, throat infection, ear infection and cold and fever and only fever as the principal symptoms. After clinical examination all the patients were prescribed for Complete Blood Count (CBC) with differential count(DC) and C-reactive protein(CRP) tests, and in children below 14 years anti-Streptolysin O(ASO) tests ( 75) were prescribed. Patients treated with antibiotics previously two weeks before the study period were not included. Qualitative and quantitative tests were performed on all patients’ samples included in the study depending on the need/prescription by the physician or paediatrician. CBC, neutrophil count and CRP have been very useful indicators and significant in the diagnosis and treatment as well as follow-up of the febrile condition of the patients specially in patients suffering with bacterial infections. Even in patients with Dengue and malaria it gives a fair idea if there were leucocytosis or leukopenia, neutrophilia or neutropenia, thrombocytosis or thrombocytopenia. CBC: Complete blood count, DC: Differential count; MP: malarial parasite, CRP: C-reactive protein, ASO: Anti-Streptolysin O.

Context.— A novel automated slide-based approach to the complete blood count and white blood cell differential count is introduced. Objective.— To present proof of concept for an image-based approach to complete blood count, based on a new slide preparation technique. A preliminary data comparison with the current flow-based technology is shown. Design.— A prototype instrument uses a proprietary method and technology to deposit a precise volume of undiluted peripheral whole blood in a monolayer onto a glass microscope slide so that every cell can be distinguished, counted, and imaged. The slide is stained, and then multispectral image analysis is used to measure the complete blood count parameters. Images from a 600-cell white blood cell differential count, as well as 5000 red blood cells and a variable number of platelets, that are present in 600 high-power fields are made available for a technologist to view on a computer screen. An initial comparison of the basic complete blood count parameters was performed, comparing 1857 specimens on both the new instrument and a flow-based hematology analyzer. Results.— Excellent correlations were obtained between the prototype instrument and a flow-based system. The primary parameters of white blood cell, red blood cell, and platelet counts resulted in correlation coefficients (r) of 0.99, 0.99, and 0.98, respectively. Other indices included hemoglobin (r = 0.99), hematocrit (r = 0.99), mean cellular volume (r = 0.90), mean corpuscular hemoglobin (r = 0.97), and mean platelet volume (r = 0.87). For the automated white blood cell differential counts, r values were calculated for neutrophils (r = 0.98), lymphocytes (r = 0.97), monocytes (r = 0.76), eosinophils (r = 0.96), and basophils (r = 0.63). Conclusions.— Quantitative results for components of the complete blood count and automated white blood cell differential count can be developed by image analysis of a monolayer preparation of a known volume of peripheral blood.

Reference Value

The reference values of laboratory tests are affected by factors such as instruments and methods of tests, which are always beingdeveloped. For these reasons, each laboratory is recommended to determine their own reference values. To determine the reference valuesof complete blood count in healthy adult people, and compare them to the reference values which is taken from the references. A crosssectional study was conducted on 200 healthy adult people, aged 18-60 years, selected during blood donation. The eight haematologicalparameters were estimated using Sysmex Xt-1800i at Dr.Wahidin Sudirohusodo Hospital. The data were analyzed statistically by SPSS11.5 programs. The reference values of leukocyte, erythrocyte, haemoglobin, hematocrit, MCV, MCH, MCHC and platelet were: 4400 to10000 /µL; %:4.2–6.2 × 106/µL; &:3.8–5.5 × 106/µL; %:12.5–17.3 g/dL; &:11.8–15.4 g/dL; %:38.1–50.4 %; &:31.1–49.7 %; 80,1to 94,3 fL, 25,9–31,9 pg, 31,4–35,2 g/dL, and %:171.2–405.1 × 103/µL; &:191.8–441.5 × 103/µL, respectively. Significant differenceswere observed in the MCH and platelet values (p< 0,005). The values found in this study were similar to the reference value commonlyused in our laboratory, except for the MCH value which was lower and the platelet value which was higher..

Acute appendicitis is one of the most common causes of acute abdominal diseases seen between the ages of 10 and 19, mostly seen in males. The lifetime risk of developing acute appendicitis is 8.6% for males and 6.7% for females. We aimed to investigate the efficacy of the complete blood count parameters, C-reactive protein, and Lymphocyte-C-reactive Protein Ratio laboratory tests in the diagnosis of acute appendicitis, as well as their relationship with appendix diameter. We retrospectively examined all patients who underwent appendectomy between 1 January 2012 and 30 June 2019 in the General Surgery Clinic of Gaziosmanpasa University Faculty of Medicine. Laboratory tests, imaging findings, age, and gender were recorded. Lymphoid hyperplasia is considered as normal appendix—in other words, as negative appendicitis. The distribution of Lymphoid hyperplasia and appendicitis rates were statistically different in the groups formed according to appendix diameter (≤6 and >6 mm) (p < 0.001). We found a significant correlation between appendix diameter and WBC (White blood count), Lymphocyte, Neutrophil, RDW(Red blood cell distribution width), NLR(Neutrophil to lymphocyte ratio), and PLT/L (Platelet to lymphocyte ratio), MPV (Mean platelet volume) and RDW were significantly different in patients with an appendix diameter of ≤6 mm (p = 0.007, p = 0.006, respectively). WBC, Neutrophil, PDW, and NLR values were significantly different between appendicitis and hyperplasia groups in patients with an appendix diameter of >6 mm. The sensitivity of the NLR score (cutoff = 2.6057) in the diagnosis of appendicitis was 86.1% and selectivity was 50% in these patients. Complete blood count parameters evaluation with the clinical findings revealed that NLR is an important parameter that may help the diagnosis of acute appendicitis with an appendix diameter of >6 mm. In patients whose pathological results indicated acute appendicitis but who had a diameter of ≤6 mm, we found an elevated MPV and low RDW values.
