ABSTRACT
Background: Changes in the course of diseases, their treatment, and care provision result in the need for a specific type of care known as palliative care. Medical staff’s knowledge and awareness of palliative care is important in this regard. Objectives: This study aims to examine the caregivers’ knowledge and awareness of palliative care and to determine the related predictors. Methods: In this cross-sectional study, 277 subjects were selected from among the caregivers working in the selected teaching hospitals in Iran through non-randomized sampling method. The subjects were asked to fill the online questionnaire which consisted of 3 sections including demographic data, knowledge, and attitude toward palliative care. Descriptive, inferential statistics, correlation and regression analyses were performed. Results: The mean scores of care providers’ attitude and knowledge were 140.90 ± 11.56 and 19.36 ± 2.73 respectively. There was a significant relationships between some variables such as working place, education level, age, palliative care-related working expe-rience, and the necessity to pass training courses and the mean scores of attitude and knowledge. Conclusions: Since palliative care providers’ level of knowledge and attitude were reported to be moderate, training courses at different levels in the form of clinical courses should be offered with the aim of improving care providers’ skills and scientific abilities. It is essential to include the related topics in the curricula of academic programs.
ABSTRACT
Background and Objectives: Several studies have focused on the alterations of hematological parameters for a better un-derstanding of the COVID-19 pathogenesis and also their potential for predicting disease prognosis and severity. Although some evidence has indicated the prognostic values of thrombocytopenia, neutrophilia, and lymphopenia, there are conflicting results concerning the leukocyte and monocyte count. Materials and Methods: In this retrospective Double Centre study, we reviewed the results of WBC and monocyte counts of 1320 COVID-19 patients (243 of whom (18.4%) had severe disease) both on admission and within a 7-day follow-up. Results: We found that both the number of monocytes and the percentage of monocytosis were higher in the severe group;however, it was not statistically significant. On the other hand, we found that not only the mean number of WBCs was significantly higher in the severe cases also leukocytosis was a common finding in this group;indicating that an increased number of WBC may probably predict a poor prognosis. Also, the monocyte count was not affected by age;however, univariate analysis showed that the percentage of leukocytosis was significantly greater in the older group (>50) with an odds ratio of 1.71 (P: 0.003). Conclusion: Alteration of monocytes either on admission or within hospitalization would not provide valuable data about the prediction of COVID-19 prognosis. Although the rapidly evolving nature of COVID-19 is the major limitation of the present study, further investigations in the field of laboratory biomarkers will pave the way to manage patients with severe disease better.
ABSTRACT
Background and Objectives: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was first de-scribed during a pneumonia outbreak in Wuhan, has attracted tremendous attention in a short period of time as the death toll and the number of confirmed cases is growing unceasingly. Although molecular testing is the gold standard method of SARS-CoV-2 detection, the existence of the false-negative results presents a major limitation to this method. Materials and Methods: This retrospective Double-Centre study was conducted on 1320 COVID-19 patients recruited at Taleghani and Shohadae Tajrish Hospitals in Tehran, Iran. We analyzed the leukocyte, lymphocyte and neutrophil counts of hospitalized cases both on admission and at discharge. We also evaluated the alteration of these parameters within a sev-en-day follow-up. Results: Of the whole, 1077 (81.6%) neither were admitted to intensive care unit (ICU) nor experienced death, and were defined as the mild-moderate group. Of 243 severe cases, while 59 (24.3%) were admitted to ICU and cured with the intensive care services, 184 (75.7%) patients died of the disease, either with or without ICU admission. Calculation of neu-trophil-to-lymphocyte ratio (NLR) revealed that the mild-moderate cases had a lower ratio at discharge. On the other hand, the ratio was significantly higher in the death group as compared to the ICU group;highlighting the fact that patients with a higher degree of neutrophilia and a greater level of lymphopenia have a poor prognosis. Conclusion: We suggest that NLR greater than 6.5 may reflect the progression of the disease towards an unfavorable clinical outcome, with this notion that the ratios higher than 9 may strongly result in death.
ABSTRACT
Background: Coronavirus disease 2019 (abbreviated as COVID-19) is a mysterious respiratory syndrome symptomatically spanning from healthy carriers to patients with life-threatening complications, in some cases, leading to a mournful death. For the time being, the contributory role of hematologists is much more recognized in the management of COVID-19, since the emergence of coagulopathy has recently been the focus of many studies in SARS-CoV-2 infection. Methods: To provide a well-conceptualized viewpoint demonstrating the prognostic value of coagulation-related laboratory tests, we planned to perform a meta-analysis of pertinent literature representing information on PT, aPTT, and D-dimer tests in patients with COVID-19. Results: Albeit the estimated pooled means of PT and aPTT were higher in severe cases, their mean values were not significantly higher as compared with patients in a non-severe condition. On the other hand, the mean value of D-dimer in severe patients was significantly higher than non-severe cases (X2=6.34, P=0.01), highlighting that the elevation of this parameter may be associated with the progression of the disease toward an unfavorable clinical outcome. Conclusion: Even though at the time of writing this article the lack of adequate and appropriate studies denotes a major limitation to the current study, planning for the future research to determine the prognostic value of laboratory tests reflecting SARS-CoV-2-induced coagulopathy, mainly D-dimer, will definitively cast a flash of light on the significance of therapeutic anticoagulation at least for those with no absolute contraindication.
