: Impedance technology was a revolution in the history of Hematology. Mispa Count X is the first indigenous 3-part hematology analyzer in India, which works on the principle of impedance technology. : Performance evaluation of Mispa Count X.: The analyzer produces the measurement results of 18 parameters with throughput of 60 samples per hour. Mispa Count X was compared with benchmark analyzers Coulter DxH 800 and Sysmex XN 1000 to validate its performance. : Mispa Count X exhibited a wide linearity range for WBC, RBC, platelet and hemoglobin. The carry over for WBC, RBC, PLT and Hb was estimated and found to be well within the acceptable limits. The r values (> 0.90) and bias estimation of Mispa Count X on comparing with Coulter DxH 800 and Sysmex XN 1000 were acceptable, except for mid cell counts and for MPV. Mispa Count X exhibited good precision with an acceptable CV% (< 10%). The primary parameters of the stored samples were stable at room temperature for 24 hours. : So we conclude our study by proving that the Mispa Count X would be an affordable-reliable alternative for Indian healthcare sector instead of expensive imported hematology analyzers.

Abstract Introduction: Devices such as the CellaVision® DM96 (CellaVision AB, Lund, Sweden) locate and image nucleated cells on blood smears. Using image recognition software, the DM96 also pre-classifies those cells into differential categories similar to the most complex hematology analyzers. We compared the cell counts, differential counts and flagging information gained from a complex hematology analyzer, the XE5000 (Sysmex, Kobe, Japan), with information from a minimal hematology analyzer (Sysmex PocHi) plus the DM96. We found that the cell counts, differential and flagging capabilities are similar, but the PocHi plus DM96 advantages include allowing remote review of the blood smear. Methods: 210 blood samples, selected for various abnormalities, had complete blood counts with automated differentials produced by a Sysmex XE5000 hematology analyzer. These results were compared with cell counts from the Sysmex PocHi hematology analyzer, their 100-cell DM96 post reclassification differentials, and with DM96 pre-classification differentials using standard regression analyses and Rumke 95% confidence intervals (CI) as calculated using the Clopper-Pearson method. Flagging by the XE5000 for immature granulocytes (IG's) and for blasts/abnormal cells was compared to the DM96 pre-classification using truth tables with the DM96 post reclassification as the gold standard. The following translations were used to compare flagging: IG's > 2 for either post reclassification DM96 differential, XE5000 or the DM96 pre-classification differential; Any blast cells on the manual differential were compared to XE5000 flags WBC Abn Scg; NRBC Abn Scg; Blasts?; Atyp LY?; Abn Ly/ L_Bl? and to DM96 pre-classification % Blasts > 0%; unidentified cells >3%. . Results: Non-differential blood count parameters including white blood count, red blood count, hemoglobin, mean corpuscular volume (MCV), and platelet count showed excellent correlation between the PocHi and the XE5000 with R2>0.95. Differential-dependent blood count parameters including neutrophils, lymphocytes, monocytes, eosinophils, basophils and immature granulocytes showed excellent correlation between the XE5000 and pre-classification DM96 with R2>0.95. Nucleated red cells also showed excellent correlation between the XE5000 and the DM96 with R2>0.85. For blasts/abnormal cells, the DM96 showed 100% sensitivity and 40% specificity with 0% false negatives. The XE5000 showed 93% sensitivity and 19% specificity with 3% false negative. Two of the false negatives were shared by both instruments and were 1% blasts. Of the three false negatives with the XE5000 that were true positives with the DM96, two had 1% blasts while one had 2% blasts. For immature granulocytes (IG's), the XE5000 showed 94% sensitivity and 79% specificity with 2% false negatives. The DM96 showed 85% sensitivity and 95% specificity with 4% false negatives. All of the false negatives were for IG's < 5% Conclusions: Pairing the DM96 or a similar imaging instrument with a relatively inexpensive hematology analyzer, such as those commonly used in physician office laboratories, would provide all of the information available from expensive, complex hematology analyzers in high throughput laboratories AND allow remote review of the blood smear findings by experts.

Abstract Hematology analyzers deliver high precision blood cell counts and a good leukocyte differential (WBCD) on normal samples. But their ability to identify and quantify abnormal cells is less good and generates a significant amount of false positive results. Routinely, about 10% to 30% of results must have manual blood film reviews, which requires considerable time and are prone to a high degree of inaccuracy, especially for the less frequent cell types (Rümke et al. 1975). In contrast, flow cytometry offers superior detection and quantification of these rare events. A Cyto Diff tube combining six antibodies (CD45, 16, 2, 36, 19 & CRTH2) analysed on a modern multicolor flow cytometer make very accurate automated WBCD feasible for abnormal samples (Feuillard J et al. ISLH 2007). The objective of the study was to evaluate the efficiency of the Cyto Diff process compared to the normal laboratory process as: The time for both methods, the labor and time savings, the relative costs of both methods including med tech time, consumables, number of residual manual review. Two Coulter LH750® hematology analysers were used for the analysis of CBC, WBCD and Reticulocyte counting. An immuno-phenotyping system, with an automatic preparator Coulter FP 1000 and an Coulter FC 500® flow cytometer were connected with a Hematology analyzer to the REMISOL data manager that requests a reflex CytoDiff tube on every sample flagged by the hematology analyzer according to the laboratory’s validation rules. The remaining samples are displayed for manual validation by an operator. The complete line is called HematoFlow. Among the 4896 non-selected CBC tests evaluated during the 10 working days of our study, 877 cases were flagged by the analyzers, reviewed manually following the normal procedure as well as analyzed on HematoFlow. Interestingly, this latter allowed: 68.8% of auto-validation by the REMISOL Data Manager, 12.8% validation directly by the operator after checking the auto-gating, 8.4% required a region readjustment before validation and finally, only 10.3% (91 of the 877-flagged samples) required further exploration because the presence of large amount of ImmGrans, Plt clumps, NRBCs, etc. In conclusion, the CytoDiff tube performs well in regular clinical lab workflow saving almost 90% of the samples flagged by the hematology analyzers for WBC abnormalities that need further exploration following current routine procedure. Our study confirmed our previous results and the fact that the standard auto-gating is set correctly needing only 8.4% of region readjustment by an operator who can be trained easily in few days. Basically, we are expecting that one operator well-trained for smear review and working on the HematoFlow line can handle the same workload as at least 3 operators at microscope stations following a current normal procedure. Furthermore, the CytoDiff approach provides additional information concerning the white blood cells in pathological context never obtained previously by cytomorphology including the detection of likely pro-inflammatory monocytes, several blast subsets, and multiple lymphocyte sub populations as well.

Context.— In the XN series of hematology analyzers (Sysmex, Kobe, Japan), the probability of the presence of abnormal cells is indicated by flags based on Q values. Objective.— To evaluate the Q value performance of the Sysmex XN-20 modular analyzer. Design.— The interinstrumental concordance, intrainstrumental precision, and diagnostic accuracy of Q values, with tested flags of “blasts/abnormal lymphocytes,” “atypical lymphocytes,” and “blasts,” were investigated. Results.— Absolute concordance rates in flagging between 2 analyzers ranged from 69.8% to 80.8%, and κ values ranged from 0.43 to 0.61. In samples with absolute related cell counts lower than 100/μL, the values ranged from 0.31 to 0.52. For intrainstrumental precision, standard deviations ranged from 4.8 to 23.9 for the blasts/abnormal lymphocytes, from 18.7 to 59.1 for the blasts, and from 11.0 to 23.0 for the atypical lymphocytes. Using a default Q value cutoff, diagnostic accuracy values based on the area under the curve, sensitivity, and specificity were, respectively, 0.910, 90.9%, and 72.2% for blasts/abnormal lymphocytes; 0.927, 84.9%, and 89.8% for blasts; and 0.865, 74.4%, and 84.9% for atypical lymphocytes. The diagnostic accuracy of Q values was much lower in samples with absolute related cell counts lower than 100/μL than in those 100/μL or higher. Conclusions.— Q values of the Sysmex XN-20 analyzer were found to be imprecise and irreproducible, especially with samples containing a small number of pathologic cells. Adjustments in the Q value threshold may help in the detection of these cells.

Abstract Background Total nucleated cell (TNC) count and differential are used to classify joint effusions as inflammatory or noninflammatory. Further diagnostic evaluation and management is contingent on this classification. TNC count can be measured by automated analyzers or by manual assessment using a hemocytometer. Studies have raised concerns regarding the accuracy of TNC counts measured by automated instruments, particularly in the setting of joint arthroplasty. The objective of this study was to determine whether metallosis, a complication of total hip arthroplasty in which metal debris accumulates in periprosthetic tissues and synovial fluid, is associated with inaccurate TNC counts in synovial fluid. Methods We compared the accuracy of cell counts measured by the Sysmex XN-1000 and Beckman Coulter Iris iQ200 with the gold standard of manual assessment using a hemocytometer in synovial fluid from patients with suspected metallosis and in fluid obtained from controls from patients with native joints and a history of arthroplasty for other indications. Results TNC counts produced by automated analyzers were associated with increased levels of discordance (relative to manual counts) in patients with metallosis. Metallosis was not associated with increased levels of discordance for RBC counts or WBC differentials. The Sysmex XN flagged all but 1 metallosis sample for manual verification of the results. Conclusions Automated methods are generally reliable for analysis of synovial fluid. TNC counts can be inaccurate in the context of metallosis following total hip arthroplasty. Laboratories should correlate automated cell counts with a microscopic assessment of the specimen, as recommended by instrument manufacturers.

Introduction: Postpartum haemorrhage is one of the leading causes of maternal death worldwide and it accounts for nearly one-quarter of all maternal deaths and almost half of all postpartum deaths in low-income countries. Primary postpartum haemorrhage (PPH) is the most common form of major obstetric haemorrhage. Materials and Methods: The study protocol was comprised of Consent, Measurement of Pre-delivery Hemoglobin, Administration of the Intervention, Measurement of postpartum blood loss and Measurement of Post-delivery (24-48 hours) Hemoglobin. Blood loss was measured using a calibrated drape. The drape was placed beneath the parturient buttocks and secured around her abdomen with ties. Blood loss was monitored for a minimum of one hour and was continued in the second hour in case of persistent bleeding. The drape with the collected blood was weighed on a scale. The weight of the drape and the container in which it is placed was deducted from the total recorded weight in order to obtain the weight of the blood collected in the drape. Blood loss weight in grams was converted to milliliters by dividing the figure in grams by 1.06 (blood density in grams per milliliter). Results: The cross tabulations were used to study the demographic, obstetrical and medical factors in women with obstetrical haemorrhage. Table 1 shows the selected sociodemographic characteristics of the study population. The mean age of cases and controls are 26.333.559 and 26.853.873 respectively. On comparison, they are statistically insignificant. (p=0.324). The educational, occupational and socioeconomic status was comparable between cases and controls (p >0.05). Table 2 shows Antenatal, intra-partum and post-partum data in cases and controls. Discussion & Conclusion: It is a study done in North India comparing the Oxytocin kept at room temperature with failure of maintenance of cold chain during transport and storage and the refrigerated Oxytocin. It is the common understanding and general training that Oxytocin must be stored in the refrigerator, failing which its efficacy reduces i.e. it, will not be effective in controlling PPH. During the study we compared the mean blood loss and change in hemoglobin levels in cases and control and despite the fact that major risk factor for PPH for example past history of PPH, past history of D&C, prolonged third stage labour duration, manual removal of placenta were comparable in both cases and controls, still the mean blood loss and change in hemoglobin values was more in cases than controls. This could be attributed to usage of market oxytocin which had failed cold chain maintenance resulted in less effective oxytocin in prevention of PPH, Hence causing more blood loss and drop in hemoglobin values. This shows the need of room temperature stable uterotonic drug in LMIC’s like ours. Recently room temperature stable carbetocin shows the potential as an effective uterotonic drug for the prevention of PPH. However according to various studies carbetocin cannot be used for induction or augmentation of labour so it cannot replace oxytocin fully, rather it acts as a part of collective PPH reduction strategy.

Sallust's style is provocative and tendentious, but does his admitted moral tendentiousness carry over into a political or partisan tendentiousness? For centuries we have heard of Sallust the partisan, Sallust the propagandist, Sallustian bias. The history of this perceived bias began at least in the age of Augustus when the anonymous writer of the Invectio in Ciceronem set stylus to wax and began his fraud. Less than a century later (before 96 A.D.) Quintilian regarded the work as genuine Sallust (I.O. 4.1.68; 9.3.89). The deception had worked; and both the fraud itself and Quintilian's acquiescence indicate a perceived anti-Gceronian bias to Sallust's writing.In the modern period, the history of perceived bias, already resisted by Voss, came to its climax in 1897 with an article by E. Schwartz which argued for a systematic and extreme anti-Ciceronian and pro-Caesarian bias and purpose to the Bellum Catilinae. The charges seemed to Schwartz necessary to explain (1) Sallust's chronology, (2) the significantly small role played by Cicero in Sallust's monograph, and (3) the report of certain rumours which implicated Cicero and Crassus and the denial of rumours which implicated Caesar. A systematic review of the arguments, however, gradually undermined or called into question the validity of most of Schwartz's points. By 1964 Syme could say that the main charges against Sallust had collapsed upon inspection. And they had; all but one.

Two samples of benzene-treated Bi–Pb–Sr–Ca–Cu–O powder exhibited at 300 K magnetic field dependent diamagnetism and magnetization irreversibility. The treatment with benzene resulted also in the appearance of microwave absorption at low magnetic fields, while is sensitive to magnetic history of the sample. From X-ray diffraction data one can see that upon benzene treatment the reflections of 85 K and 110 K phases do not change practically, but a series of new reflections appeared, indicating a lattice modulation with 4.9 nm periodicity. A microprobe analysis revealed substantial inhomogeneity of chemical composition across the samples. The room temperature anomalies were weakened in one sample and vanished in the second upon thermal cycling.
