Introduction: The diagnostic value of the D-dimer test varies with variable platelet numbers and functions in patients suffering from cancer and concomitant pulmonary thromboembolism (PTE). This requires easy and reliable evaluation tests. In this study, we aimed to investigate the hypothesis that platelet functions may be more guiding in the prediction and diagnosis of PTE rather than the number of platelets in cancer pa- tients. Methods: The clinical, laboratory and radiological findings of all patients diagnosed with PTE were retrieved, retrospectively. Comparisons were performed between “can- cer-free” and “cancer” patients. The patients were also evaluated according to their active and remission status. Results: The data of 232 patients with PTE were reviewed. 172 patients were cancer- free and 60 were diagnosed with cancer. The mean values of D-dimer, mean platelet volume (MPV) and platelet distribution width (PDW) were found to be significantly higher in patients with cancer (P=0.015, P=0.026, and P=0.023; respectively). On the other hand, mean platelet counts were significantly higher in patients without cancer (P=0.05). It was also observed that the mean values of D-dimer, Troponin-I, MPV, and PDW were found to be significantly higher in patients with active cancer (P=0.05, P=0.044, P=0.05, and P=0.042; respectively). However, the mean platelet counts were significantly higher in patients with cancer who were in remission (P=0.05). Conclusions: The morphological characteristics of the platelets are more determinant than the number of platelets in cancer patients with PTE. Platelet indexes such as MPV and PDW may be useful in the prediction, diagnosis, and follow-up of PTE in patients with cancer.

Abstract Introduction Traumatic brain injury (TBI) affects the coagulation pathway in a distinct way than does extracranial trauma. The extent of coagulation abnormalities varies from bleeding diathesis to disseminated thrombosis. Design Prospective study. Methods The study included 50 patients of isolated TBI with cohorts of moderate (MHI) and severe head injury (SHI). Coagulopathy was graded according to the values of parameters in single laboratory. The incidence of coagulopathy according to the severity of TBI and correlation with disseminated intravascular coagulation (DIC) score, platelets, prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer, and fibrinogen was observed. The comparison was also made between expired and discharged patients within each group. It also compared coagulation derailments with clinical presentation (Glasgow Coma Scale [GCS]) and outcome (Glasgow Outcome Scale [GOS]). Results Road traffic accident was the primary (72%) mode of injury. Fifty-two percent had MHI and rest had SHI. Eighty-four percent of cases were managed conservatively. The mean GCS was 12.23 and 5.75 in MHI and SHI, respectively. Sixty-two percent of MHI and 96% of the patients with SHI had coagulation abnormalities. On statistical analysis, DIC score (p < 0.001) strongly correlated with the severity of head injury and GOS. PT and APTT were also significantly associated with the severity of TBI. In patients with moderate TBI, D-dimer and platelet counts showed association with clinical outcome. Fibrinogen levels did not show any statistical significance. The mean platelet counts remained normal in both the groups of TBI. The mean GOS was 1.54 and 4.62 in SHI and MHI, respectively. Conclusion Coagulopathy is common in isolated TBI. The basic laboratory parameters are reliable predictors of coagulation abnormalities in TBI. Coagulopathy is directly associated with the severity of TBI, GCS, and poor outcome.

Abstract Background Stroke (cerebrovascular accident) has for long been a global burden in terms of its morbidity and mortality. Serum levels of cardiac enzymes such as creatine kinase-MB (CK-MB) component, troponin T, and brain natriuretic peptide have been found to be elevated among the patients with stroke and also serve to prognosticate these patients. The serum levels of these enzymes correlate directly to the severity of stroke in these patients. Objective Elevated cardiac enzymes among patients with acute cerebrovascular accidents are not uncommon despite the patients not having any cardiac problems. We aimed to identify the occurrence of elevated cardiac enzymes among patients with acute stroke and their correlation with the severity of stroke. Materials and Methods Our study included 100 patients of acute stroke with no previous history of cardiac ailments. Serum levels of troponin I and CK-MB were analyzed among these patients using enzyme-linked immunosorbent assay method within the first 2 hours of admission. Patients outcome during the hospital stay were analyzed. Stroke severity was assessed using the National Institute of Health Stroke score (NIHS score) and the modified Rankin Score (mRS). The cardiac enzyme levels were correlated with these scores. Results Twenty-eight percent of patients had elevated troponin I, while 72% patients had normal levels with the mean values of 10.36 to 106.54 ng/mL and 0.00 to 0.02 ng/mL, respectively. CK-MB levels were found elevated among 14% patients and normal among 86% patients with mean values of 5.8 to 124.36 and 0.0 to 4.3 ng/mL, respectively. Among the six patients who succumbed to death, three patients had increased troponin I and four had elevated CK-MB. NIHS scores of 21.0357±6.79 and 105.277±5.564 were seen in patients with elevated and normal troponin I, whereas NIHS scores of 20.4285±8.658 and 11.8721±9.273 were seen among patients with increased and normal CK-MB, respectively. The mRS scores were 4.3214±0.367, 2.4305±1.374, 4.2143±1.412, and 2.756±1.749 ng/mL among the patients with elevated and normal troponin I and CK-MB, respectively. Conclusion The mean values of cardiac enzymes troponin I and CK-MB were higher among patients with higher scores of NIHS and mRS. Among them, troponin I was very significant and it may serve as an early biomarker for the severity of stroke and hint on early cardiac evaluation among these patients.

Gongronema Latifolium

The hematological features of Gongronema latifolium, aqueous leaves extract was evaluated using standard methods. After 10 days of consecutive infusions into 9 experimental animals (rabbits). The rabbits were monitored and the following parameters determined; hemoglobin (HB), PCV, Platelet, WBC, Differential White Blood Cell. The Rabbits were grouped into 4, one consisting of control (group A), group B was fed with 0.5 mg/kg, group C with 1.0 mg/kg, and Group D with 1.5mg/kg of the aqueous extract of Gongronemalatifolium. The mean values obtained for hemoglobin estimation for the control group is 5.9 ± 4.1 g/dl, 9.1 ± 2.9 g/dl for group B 10.2 ± 1.8 g/dl for group C and 12.8 ± 0.1 g/dl for group D with no significant increase on the PCV estimation, the mean value for the control (group A) is 17.7 ± 12.3%, 27.3 ± 8.7% for group B, group C (30.6 ± 5.4%) and D (28.4 ± 0.3) show increase that statistically significant (p > 0.01). the platelet counts of group C (600 ± 0 x 109/L) and D(600 ± 0 x 109/L) show significant increase (p > 0.01) when compared with the control (600 ± 00). But the platelet value of group B (550 ± 50 x 109/L) shows no difference. No significant changes were observed in the White Blood Counts of the test groups B (3.5 ± 0.5 x 109/L), C (1.9 + 2.1 x 109/L) and D(3.6 ± 0.4) when compared with the control group (2.9 ± 1.9). The values obtained from the differential White Blood Counts (Neutrophils, Lymphocytes, Eosinophils and Monocytes) were not significant. Therefore, Gongronemalatifolium, when properly taken as a nutritional diet, causes beneficial changes on hemoglobin, packed cell volumes and platelet counts of consumers.

Similar Incidence

Half of the cases of pulmonary thromboembolism (PTE) are not diagnosed because of its unspecific clinical presentation; in Mexico, autopsy data reveal a similar incidence to that of developed countries. The objective of this work was to know the concordance between the clinical diagnosis of PTE at hospital discharge and its autopsy diagnosis. The method used was a retrospective cohort study of cases with PTE diagnosis who attended from January 2005 to December 2013. Information was obtained from the autopsies registry and clinical charts. From 177,368 hospital discharges, there were 412 (6.74%) with PTE diagnosis. There were 13,559 deaths, with PTE diagnosis in 139 (1%) patients. There were 479 autopsies, and in 66 (14%) of whom PTE diagnosis was documented, the mean age was 55 years (range, 18–89 years). The premortem diagnosis of PTE at discharge was confirmed in 412 cases. Postmortem diagnosis of principal disease was medical in 49 (74%) and medical-surgical in 17 (26%) patients. We found that nine patients had the clinical diagnosis of PTE, unlike the postmortem diagnosis, which was reported in 66 autopsies. The above allows establishing a 1:7 ratio that represents 14%. D-dimer was determined in 11 cases (16%) and was positive in 8 (73%). Thromboprophylaxis was applied in 15 cases (23%). The study of necropsies and identification of discrepancies is needed to improve the diagnostic accuracy and healthcare quality. The evaluation of hemostasis biomarkers besides D-dimer can better describe the pro-thrombotic state, the risk of thrombosis, and its association with morbidity and mortality.

At the moment the suitability of stored red blood cells (sRBC) for transfusion is checked by routine methods such as haemoglobin estimation and the level of haemolysis. These methods cannot characterize directly the quality of the membranes of sRBC. The aim of this work is to assess the quality of sRBC based on such criteria as the membrane’s stiffness and the size and the form of sRBC. Materials and Methods. We have investigated 5 series of dry cytosmears of the sRBC which had been kept in blood bank in a period from 1 to 35 days. After AFM imaging, in every specimen, 5 RBC were chosen at random; the diameter, the height, and the stiffness were measured on each of them. Results. The present study shows high increase of the mean values of YM and height of RBC after 35 days of storage and decrease of the mean values of their diameter. Conclusion. Statistically significant high increase of the mean values of YM indicates the decrease of the elasticity of the cells in the course of storing of the RBC. This parameter along with the morphological characteristics can be used as criterion for assessment of applicability of the sRBC for blood transfusion.

Objective: Findings suggest dissatisfaction of half of the cancer patients regarding pain and anxiety management. This study aimed to determine the effect of reflexology on the intensity of pain and anxiety among patients with metastatic cancer hospitalized inadulthematology ward.  Methods: In this study, the samples were selected from adult hematology ward in Baghaei 2 hospital in Ahwaz, Iran, according to the inclusion criteria. They were then assigned into treatment and control groups. In the treatment group, reflexology protocol was performed following manual reflexology method by Fr Josef Eugster based on Ingham method on the patient’s bed. In the control group, sole touching was used as the placebo. Reflexology was performed for three days, 30 min per day. Spielberger questionnaire were provided to the samples and completed in the first and third days, and Spielberger questionnaire was provided to the samples and completed. The data obtained from this study were then analyzed by SPSS 20.Results: The two groups did not show a significant difference in terms of demographic characteristics (p>0.05). Based on the obtained results, it was found that in the test group, there was a significant difference between the mean intensity of pain before and after the treatment across all 3 days as well as the mean anxiety of the 1st and 3rd days (p<0.05). However, in the control group, there was no significant difference in terms of mean pain intensity before and after the treatment across 3 days (p>0.05). No significant difference was observed between the mean anxiety of the 1st and 3rd days either (p>0.05).Conclusion: Considering the findings of this research, it can be concluded that reflexology has a positive effect on mitigating the intensity of pain and anxiety in metastatic cancer patients. Therefore, it is recommended that nurses employed in cancer centers benefit from the findings of this research to further help patients with cancer. It is also suggested that further research be conducted on the effect of reflexology on the pain and anxiety of other patients.

e20509 Background: Low-molecular weight heparin (LMWH) is preferred over warfarin in patients with thromboembolic disease and active cancer, but no guidelines exist in hospice. Although warfarin may be less safe in hospice patients, hospices may prefer to provide warfarin due to lower cost and less invasiveness compared to LMWHs. We sought to identify disparities in the use of warfarin vs. LMWHs in cancer patients enrolled in hospice. Methods: We analyzed a dataset from a national pharmacy provider for more than 800 hospices. We identified patients with a terminal diagnosis of cancer who were enrolled and died in hospice in 2006 and who were prescribed warfarin or LMWH. Patient characteristics included age, gender, race, cancer diagnosis, length of hospice service, and number of comorbidities. For descriptive comparisons, the Kruskal-Wallis test was used for continuous variables, and the Chi-square test was used for categorical variables. Results: Of 54,764 patients with cancer admitted and deceased in 2006, 3874 (7.1%) were prescribed warfarin, and 1137 (2.1%) were prescribed LMWH. Patients prescribed warfarin (n=576) or enoxaparin (n=5) for treatment of atrial arrhythmias were excluded. The mean age was 70.6 years for warfarin and 64.8 years for LMWH (p<0.0001). The mean and median lengths of service, respectively, were 43.6 days and 23.0 days for warfarin and 35.0 and 18.0 days for LMWH, (p<0.0001). There were no differences for gender, and a higher proportion of white patients were prescribed warfarin. Patients prescribed warfarin had an average of 2.1 comorbid conditions, versus 1.6 conditions for LMWH (p<0.0001). Cancer diagnoses were significantly different between the two groups, with a higher proportion of patients with lung and prostate cancer taking warfarin. Conclusions: Patients prescribed warfarin were older, had more comorbidities, and a longer length of service than patients prescribed LMWHs. Further research is needed to determine the impact of anticoagulation on outcomes, especially cost and quality of life, for cancer patients in hospice. This study raises the need to establish guidelines for the appropriateness of anticoagulation in hospice patients with cancer. No significant financial relationships to disclose.

Coronavirus disease 2019 (COVID-19) is the third known animal coronavirus, after severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome coronavirus (MERS-CoV). The mean age of the infected patients was estimated to be between 50 and 69 years old. Accordingly, the COVID-19 mortality rate was calculated as 15%. In this regard, the essential component of prevention and planning is knowledge of laboratory and demographic findings among COVID-19 patients; therefore, the present study was conducted to investigate laboratory and demographic findings among these patients worldwide. This systematic review was performed on the articles published in English between January 1, 2019 and May 4, 2020, using MeSH-compliant keywords such as "COVID-19", "Laboratory, coronavirus disease-19 testing", and " demography " in international databases (PubMed, and web of science Scopus). Thereafter, the articles relevant to laboratory and demographic findings among COVID-19 patients were included in the final review. Reviewing the included articles showed changes in the mean lymphocytes count ranged from 0.7 to 39 in hospital or severe cases. Moreover, Leukopenia was not observed in patients with thrombocytopenia. In addition, C-reactive protein (CRP), leukocytes, D-dimer, FDP, FIB, neutrophils, AST, serum creatinine, t-troponin, troponin I, and blood bilirubin levels showed increasing trends in most studies conducted on COVID-19 patients. Notably, the elevated LDH level was more common among children than adults. According to the results of the present study, and by considering the clinical characteristics of COVID-19 patients on the one hand, and considering the changes in laboratory samples such as lymphocytes and other blood markers due to the damaged myocardial, hepatic, and renal tissues on the other hand, it is recommended to confirm the diagnosis of this infection by evaluating the patients’ blood samples using other diagnostic methods like lung scan.

The paper presents the results of the research conducted within the European provenance beech trial, in the Teaching Base of the Faculty of Forestry - Debeli Lug. To assess the inter- -provenance genetic variability of beech, using morphological markers, and comparative analysis of the results obtained in two successive years, 10 trees per each selected provenance were sampled. Thirty leaves were collected from each tree (total of 300 leaves per provenance per year). The inter-provenance differences of all morphological leaf characteristics were statistically significant and can be assumed to be the result of the genetic constitution of the provenances themselves. Based on the comparative analysis of the morphological characteristics of beech leaves from 13 different provenances in two research years, it was found that the mean values of most analyzed morphological characteristics were higher in 2017, compared to the results from 2016. Such results could be explained by the different climatic conditions that prevailed in the provenance trial in research years.
