Background: Visually estimated blood loss has long been known to be im-precise, inaccurate, and often underestimated, which may lead to delayed di-agnosis and treatment. Aim: To determine the accuracy of blood estimates by health workers in surgical and obstetric specialties. Methodology: This was a cross sectional single blinded observational study done in January 2016 to determine discrepancy between actual blood loss (ABL) and estimated blood loss (EBL) by consenting healthcare practitioners working in various surgical and obstetric departments of the federal medical centre, Owerri. Reconsti-tuted whole blood was obtained from the blood bank, and simulated scena-rios with known measured blood loss were created using common surgical materials. Visually estimated blood loss was performed by medical personnel. Percent errors of estimated blood loss were calculated and comparisons were made among the health professionals. The statistical analysis was done using SPSS version 21. Results: A total of 113 health professionals comprising 64 doctors and 49 nurses assessed 7 clinical scenarios. On the average, there was a general tendency for the health workers to under estimate the volume. Ma-jority of the participants underestimated the blood volume by more than 20% of actual volume. Though the nurses were more likely to underestimate blood volume than the doctors however, there was no statistical difference between the estimations by the nurses and the doctors except in station 3 with a p val-ue of 0.045. Conclusion: This finding calls for action in training and retrain-ing of every health worker in blood loss estimation, so that intervention can be initiated early.

Heart Failure (HF) is a syndrome characterized by typical symptoms (e.g. breathlessness, ankle swelling and fatigue) that may be accompanied by signs (e.g. elevated jugular venous pressure, pulmonary crackles and peripheral oedema) caused by a structural and/or functional cardiac abnormality, resulting in a reduced cardiac output and/or elevated intracardiac pressures at rest or during stress. Clinical studies investigating the aetiological patterns of heart failure in Sub-Saharan Africa (SSA) revealed that hypertension, cardiomyopathy and rheumatic heart disease account for more than two-thirds of cardiac disease cases. The objective of this study therefore is to assess the pattern, precipitating factors and short term outcome of heart failure among patients admitted into our hospital. Method: The study was a prospective cross-sectional type conducted among in patients with heart failure in the medical ward of the hospital. Results: A total of three and fifty four (354) subjects were recruited into the study, comprising one hundred and twenty nine males (36.4%) and two hundred and twenty five (63.4%) females. Majority of the patients were admitted in NYHA functional class IV. This however improved to class II at discharge though few were discharged in NYHA class III. Heart failure secondary to progressive hypertensive heart disease was the most common (39.0%) followed by peripartum cardiomyopathy (22.6%) while idiopathic dilated cardiomyopathy (11.0%) and rheumatic heart disease (7.3%) were the third and fourth causes of heart failure respectively. The most common precipitating factor for heart failure in this study was chest infection (44.9%). In conclusion, the study revealed that progressive hypertensive heart disease was the leading cause of heart failure, followed by peripartum cardiomyopathy while idiopathic dilated cardiomyopathy and rheumatic heart disease were ranked third and fourth causes of heart failure respectively.

Background: Evaluating the tumor proliferative index helps predict clinical behavior and provides prognostic insights for cutaneous basal cell carcinoma (cBCC) and squamous cell carcinoma (cSCC). Objective: This study aimed to identify differences in the proliferative indices among variants of cBCC and cSCC diagnosed at a tertiary healthcare center. Method: Skin biopsies histologically diagnosed as cBCC and cSCC between 2012 and 2018 at the federal medical centre (FMC) Umuahia, Abia State, Nigeria, were analyzed. Archival formalin-fixed, paraffin-embedded (FFPE) tissue blocks were retrieved along with clinical data, and were prepared on charged microscope slides and the immunohistochemical staining was carried out. The primary antibody used in this study was clone BioCare CRM325C (RM) and adenotonsillar tissue blocks/slides served as positive controls. Ki-67 immunohistochemistry was performed on fresh 4µm sections of the tumor specimens. Results: The application of Ki-67 immunoperoxidase on both BCC and SCC cohort, yielded an intense observable brownish nuclear stain in areas of dense proliferating tumour cells on both cutaneous tumours. The average Ki-67 index for all cSCC cases was 24.7%, with a range of 2.3% - 80%, while the mean for cBCC was 15.8%, ranging from 1.2% - 45.6%. Variants with high proliferative indices were observed in 11.9% of cBCC cases and 29.1% of cSCC cases. Among the low proliferative index category, cSCC accounted for 5.4%, while cBCC represented 14.3%. For mild proliferative indices, cSCC cases made up 7.3% and cBCC, 11.9%. The majority of cases showed moderate proliferative indices, with 61.9% for cBCC and 58.2% for cSCC. Overall, there was a significant difference in proliferative indices between cSCC, cBCC, and their variants. Conclusion: The study found a significantly higher rate of cell proliferation, measured by Ki-67 immunostaining, in cSCC and its variants compared to cBCC. However, certain variants of cBCC also exhibited high Ki-67

Role of the Rossiter-McLaughlin effect in the study of close binaries

引用

Research in Astronomy and Astrophysics 2019年第3期19卷 21-30页

作者： Galina N.Dryomova Vladimir V.Dryomov Russian federal Nuclear centre

This paper is devoted to binary stars belonging to the class of eclipsing-variable *** and spectroscopic analysis of eclipses allows us to determine geometric parameters of the orbit and physical characteristics of stellar components as well as inclinations of stellar equators to the orbital plane. Estimations of inclinations can be obtained from measurement of the Rossiter-McLaughlin effect, which is discussed using examples of some eccentric binaries with an anomalous apsidal effect. Our task is to find the complete spectrum of solutions of the equation of apsidal motion, depending on the inclinations of the polar axes of the components to the orbital one for these systems, based on their individual spectroscopic and photometric observational data. The matrix of solutions allows us to select those pairs of polar inclinations that provide agreement with the observational apsidal period.

Forecasting the effects of EU policy measures on the nitrate pollution of groundwater and surface waters

引用

Journal of Environmental Sciences 2010年第6期22卷 872-877页

作者： Ralf Kunkel Peter Kreins Bjrn Tetzlaff Frank Wendland Research centre Jülich Institute of Chemistry and Dynamics of the Geosphere Institute of Rural Studies Federal Agricultural Research Centre

We used the interdisciplinary model network REGFLUD to predict the actual mean nitrate concentration in percolation water at the scale of the Weser river basin （Germany） using an area differentiated （100 m × 100 m） approach. REGFLUD combines the agro-economic model RAUMIS for estimating nitrogen surpluses and the hydrological models GROWA/DENUZ for assessing the nitrate leaching from the soil. For areas showing predicted nitrate concentrations in percolation water above the European Union （EU） groundwater quality standard of 50 mg NO3-N/L, effective agri-environmental reduction measures need to be derived and implemented to improve groundwater and surface water quality by 2015. The effects of already implemented agricultural policy are quantified by a baseline scenario projecting the N-surpluses from agricultural sector to 2015. The REGFLUD model is used to estimate the effects of this scenario concerning groundwater and surface water pollution by nitrate. From the results of the model analysis the needs for additional measures can be derived in terms of required additional N-surplus reduction and in terms of regional prioritization of measures. Research work will therefore directly support the implementation of the Water Framework Directive of the European Union in the Weser basin.
