ABSTRACTIntroductionThis retrospective study investigated the implications of changes in blood parameters and cellular immune function in patients with 2019-coronavirus infected disease (COVID-19).MethodsRecords were reviewed of 85 patients with COVID-19 between February 4 and 16, 2020. The primary outcome was in-hospital mortality at 28 days.ResultsFourteen patients died. The baseline leukocyte count, neutrophil count and hemoglobin was significantly higher in non-survivors compared with survivors, while the reverse was true of lymphocyte count, platelet, PaO2/FiO2, CD3+ count and CD4+ count. The percentage of neutrophil count > 6.3×109/L in death group was significantly higher than that in survival group, and multivariate logistic regression showed neutrophil count was independently associated with mortality. However, there were not significant difference in IgG, IgM, IgA, C3, C4 and the percentage of IgE > 100 IU/ml between the death group and survival group. Areas under the receiver operating characteristic curves of the following at baseline could significantly predict mortality: leukocyte, neutrophil, lymphocyte, CD3+ and CD4+ counts.ConclusionsFor patients with COVID-19, lymphocyte, CD3+ and CD4+ counts that marked decrease suggest a poor outcome. A high neutrophil count is independently associated with mortality. At admission, leukocyte, neutrophil, lymphocyte, CD3+ and CD4+ counts should receive added attention.

Background: Coronavirus disease-19 (COVID-19) has become a world wellbeing compromise. The danger factors for unfavorable occasions of coronavirus disease-19 (COVID-19) have not been very much depicted. This study aimed to explore clinical characteristics, laboratory results, and CT imaging characteristics of COVID-19 patients in Midnapore medical college and hospital and provide evidence for the prevention and treatment of COVID-19.Methods: In this retrospective, single-center study, data of all confirmed patients with COVID-19 admitted at SARI HDU of Midnapore medical college and hospital from 1st July to 21July 2021 were collected and analyzed. Data including clinical presentations, basic laboratory investigations, and CT severity scores were analyzed and compared between survival and death patients.Results: In this study total of 81 patients of COVID-19 admitted at SARI HDU were included (male=50, female=31). The patients were divided into 2 groups according to the outcome: survival group (n=38) and death group (n=43). Information on the overall clinical characteristics of the patients was collected, including age, sexual orientation, past medical history, clinical symptoms, and so on. Compared with the patients in the Survival group, the patients in the death group, the proportion of patients presented with Dyspnoea and suffering from Diabetes and hypertension were higher (p<0.05). In patients of the death group, TLC, CRP, D-dimer, urea, and creatinine had higher values, while the levels of albumin were significantly reduced, and the differences were statistically significant (p<0.05). Between the Survival group and death group, there was no significant difference in other indexes such as NLR, platelet count, and liver enzymes (SGOT, SGPT) (p>0.05). Conclusions: The risk factors of comorbidities, like diabetes, hypertension and others like leucocytosis, high CRP, high d-dimer, altered renal function, low serum albumin, and higher CT severity score could help clinicians identify patients with potential adverse events.

Abstract Background This study aimed to study the value of brain natriuretic peptide (BNP) and cardiac troponin I(cTnI) for predicting the prognosis in cancer patients with sepsis. Methods A cohort of 233 cancer patients with sepsis admitted to our ICU from January 2017 to October 2020 was included in this retrospective study. BNP and cTnI on the first day (d1) and the third day(d3) after entering ICU, blood lactate (Lac), procalcitonin (PCT), Leucocyte, Sequential Organ failure assessment (SOFA) scores, the incidence of septic shock, acute kidney injury(AKI), acute respiratory failure (ARF) requiring mechanical ventilation(MV) and sepsis-induced myocardial dysfunction(SIMD) within 24 hours of entering ICU, fluid balance in 24hr and 72hr of entering ICU, time of MV, length of stay in ICU ,emergency surgery were collected. According to the 28-day mortality, these patients were divided into the survival group (190 cases) and the death group (43 cases). All the above variables were compared. Results The multiple COX regression analysis of these variables indicated that BNP on d1 and d3, SOFA scores ,72hr fluid balance were independent predictors of the mortality in these patients (P < 0.05); The area under the ROC curve was 0.91 ± 0.01(P < 0.05) for BNP on d3. BNP on d3 at 681.5 pg/mL predicted the mortality with a sensitivity of 91.5% and a specificity of 88.7%. All patients were divided into two groups (BNP on d3 < 681.5 pg/ml or > 681.5 pg/ml), Kaplan-Meier analysis performed on the two groups showed a significant difference in the survival curve (P < 0.05) .There were also significant differences on the comorbidities including shock, AKI, ARF in both groups (P < 0.05). 126 out of 233 patients underwent random bedside echocardiography, and a total of 42 cases developed SIMD with an incidence rate of 33.3% (30.6% in the survival group and 40.9% in the death group). There was no significant difference in the incidence of SIMD between the survival group and the death group (P = 0.23). There was a significant difference between the non-SIMD and the SIMD group for BNP on d1 and d3(P < 0.05). Conclusions BNP was a great predictor for the prognosis of cancer patients with sepsis, while cTnI was not.

Background: In the early period of spontaneous circulation (ROSC), the body may show severe immunosuppression and excessive activation of inflammatory response, This is very similar to sepsis in many ways. Objective: The aim of this study is to observe changes of the early expression of monocyte human leukocyte antigen DR in patients with cardiac arrest, so as to explore the clinical significance of the related immune assessment and prognosis prediction. Methods: A total of 43 patients with cardiac arrest who have been treated in the emergency department of Beijing Chaoyang Hospital from January 2015 to February 2018 are selected. By taking the survival rate on the 28th day of hospitalization as the end of observation, the patients are divided into the survival group and the death group. Changes of APACHE-II scores and monocyte human leukocyte antigen DR levels on the first, second, and third day after admission are analyzed. Results: On the first, second, and third day after onset, cardiac arrest patients show significantly decreased levels of monocyte human leukocyte antigen DR which are obviously lower in the death group than in the survival group. In addition, human leukocyte antigen DR levels were significantly negatively correlated with APACHE-II scores. Conclusion: The expression of monocyte human leukocyte antigen DR is proven to be an ideal indicator to evaluate the immune function and prognosis of cardiac arrest patients. A constantly low expression of human leukocyte antigen DR indicates impaired immune function and increased mortality of patients.

The aim of this study is to investigate the routine blood parameters of COVID-19 patients at the time of admission to the emergency department and their relationship with the severity of the disease and prognosis. A total of 500 patients, who were diagnosed with severe COVID-19 and hospitalized in the intensive care unit between 01.04.2020 and 01.02.2021 in the emergency department of a pandemic hospital, were retrospectively analyzed. Demographic, clinical, and laboratory data of the patients were obtained from the hospital registry system. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) were calculated using neutrophil, lymphocyte, monocyte, and platelet counts. These patients were divided into two groups: survivors and deceased. All parameters obtained from routine blood analysis were statistically compared between these two groups. While 280 out of 500 patients survived, 220 died. Of all patients, the mean age was 67 years and 51.8% were males. There was a significant difference between the two groups in terms of age, gender, length of hospital stay, need for mechanical ventilation, white blood cell, neutrophil, lymphocyte, monocyte, eosinophil, platelet counts, CRP, ferritin, procalcitonin values, NLR, MLR, and PLR ( p < 0.001 for all). While NLR alone and MLR + NEU and NLR + PLR + MLR combinations had the highest AUC values (0.930, 0.947, and 0.939, respectively), MLR and PLR alone showed the lowest AUC values (0.875 and 0.797, respectively). The sensitivity, specificity, positive predictive values (PPVs), and negative predictive values (NPVs) in the prediction of death according to the cutoff values of the parameters have been determined. A significant correlation was determined between age, NLR, MLR, and PLR and duration of hospital stay ( p < 0.001 for all). Routine blood parameters and NLR, MLR, and PLR can assist emergency physicians to identify the severity and early prognosis of COVID-19 patients.

Objective. To explore risk factors for death from cardiomyopathy and the effectiveness of health information management (HIM). Methods. A total of 80 patients with cardiomyopathy admitted in ICU of our hospital (January 2016–January 2020) were selected as study subjects, and the clinical data of the patients were retrospectively analyzed. The patients were divided into the survival group (n = 72) and the death group (n = 14) according to the treatment outcome. Then, according to the management mode, the survival group was further equally divided into the conventional group and the HIM group to investigate the influence of risk factors on prognosis of patients with cardiomyopathy and the effectiveness of HIM. Results. No significant difference was found in baseline body mass, myocardial enzymes, troponin, infection factors, history of heart disease, and gender between the survival group and the death group ( P  > 0.05). Compared with the survival group, the patients of the death group were older ( P  < 0.05), LVEF of the death group was obviously lower ( P  < 0.05), and the scores of APACHE II and SOFA of the death group were obviously higher ( P  < 0.05). Further logistic regression analysis of the univariate factors influencing the risk of death from cardiomyopathy led to the conclusion that LVEF was an independent risk factor for death in patients with cardiomyopathy. LVEF below 24.69% examined by echocardiography had a high predictive value, with a sensitivity of 98.6% and a specificity of 78.6%. No obvious difference was found in general data between the conventional group and the HIM group ( P  > 0.05). Compared with the conventional group, the disease remission rate, complication rate, awareness rate of health knowledge, ICU length of stay, and scores of self-management efficacy of the HIM group were obviously better ( P  < 0.05). No significant difference was found in 5-year mean survival rate between the conventional group and the HIM group ( P  > 0.05). Conclusion. Older age, lower LVEF, and higher scores of APACHE II and SOFA are all risk factors for death from cardiomyopathy. Lower LVEF is an independent risk factor, and LVEF below 24.69% is an important indicator of increased risk of death. Moreover, HIM can effectively improve short-term treatment efficacy but has little effect on the long-term survival rate.

Purpose: To understand the association between biomarkers and exacerbations of severe asthma in adult patients in Taiwan. Materials and Methods: Demographic, clinical characteristics and biomarkers were retrospectively collected from the medical charts of severe asthma patients in six hospitals in Taiwan. Exacerbations were defined as those requiring asthma-specific emergency department visits/hospitalizations, or systemic steroids. Enrolled patients were divided into: (1) those with no exacerbations (non-exacerbators) and (2) those with one or more exacerbations (exacerbators). Receiver operating characteristic curves were used to determine the optimal cut-off value for biomarkers. Generalized linear models evaluated the association between exacerbation and biomarkers. Results: 132 patients were enrolled in the study with 80 non-exacerbators and 52 exacerbators. There was no significant difference in demographic and clinical characteristics between the two groups. Exacerbators had significantly higher eosinophils (EOS) counts (367.8 ± 357.18 vs. 210.05 ± 175.24, p = 0.0043) compared to non-exacerbators. The optimal cut-off values were 292 for EOS counts and 19 for the Fractional exhaled Nitric Oxide (FeNO) measure. Patients with an EOS count ≥ 300 (RR = 1.88; 95% CI, 1.26–2.81; p = 0.002) or FeNO measure ≥ 20 (RR = 2.10; 95% CI, 1.05–4.18; p = 0.0356) had a significantly higher risk of exacerbation. Moreover, patients with both an EOS count ≥ 300 and FeNO measure ≥ 20 had a significantly higher risk of exacerbation than those with lower EOS count or lower FeNO measure (RR = 2.16; 95% CI, 1.47–3.18; p = < 0.0001). Conclusions: Higher EOS counts and FeNO measures were associated with increased risk of exacerbation. These biomarkers may help physicians identify patients at risk of exacerbations and personalize treatment for asthma patients.

One of the urgent problems of nursing premature babies is the timely prediction, diagnosis and treatment of anemia, the frequency of which reaches 90%. Of particular importance is the study of reticulocytic blood parameters in deep-premature newborns, since the correct assessment of hemograms is crucial in the management of this category of children. To determine the characteristics of red blood cells and reticulocyte parameters of venous blood hemogram in premature newborns 24-32 weeks of gestation in the dynamics of the neonatal period. 111 newborns were examined at 24-32 weeks of gestation in the early neonatal period (on day 3-7) and at the age of 1 month of life. Along with standard diagnostic procedures, in accordance with current clinical recommendations and standards, 28 parameters of erythrocyte and reticulocyte hemogram parameters were determined for children. Venous blood was examined using an automatic hematological analyzer ADVIA 2120i, Siemens, USA. In deep-premature newborns in the early neonatal period, there is a high activity of erythropoiesis, respectively, the severity of respiratory and metabolic disorders with rejuvenation of reticulocytic subpopulations. Negative values of Delta hemoglobin were found against the background of a decrease in the average amount of hemoglobin in reticulocytes in children 24-27 weeks of gestation, which characterizes the lowest values of iron availability for erythropoiesis in this category of newborns. It is shown that a decrease in reticulocyte counts and normochromia in all examined newborns by the age of one month are accompanied by high levels of immature reticulocyte fraction, while a third of children still have limited iron availability for erythropoiesis.
