Critically ill patients with COVID-19 pneumonia suffered both high thrombotic and bleeding risk. The effect of SARS-CoV-2 on coagulation and fibrinolysis is not well known. We conducted a retrospective study of critically ill patients admitted to an intensive care unit (ICU) a cause of severe COVID-19 pneumonia and we evaluated coagulation function using rotational thromboelastometry (ROTEM) on day of admission (T0) and 5 (T5) and 10 (T10) days after admission to ICU. Coagulation standard parameters were also evaluated. Forty patients were enrolled into the study. The ICU and the hospital mortality were 10% and 12.5%, respectively. On ICU admission, prothrombin time was slightly reduced and it increased significantly at T10 (T0 = 65.1 ± 9.8 vs T10 = 85.7 ± 1.5, p = 0.002), while activated partial thromboplastin time and fibrinogen values were higher at T0 than T10 (32.2 ± 2.9 vs 27.2 ± 2.1, p = 0.017 and 895.1 ± 110 vs 332.5 ± 50, p = 0.002, respectively); moreover, whole blood thromboelastometry profiles were consistent with hypercoagulability characterized by an acceleration of the propagation phase of blood clot formation [i.e., CFT below the lower limit in INTEM 16/40 patients (40%) and EXTEM 20/40 patients (50%)] and significant higher clot strength [MCF above the upper limit in INTEM 20/40 patients (50%), in EXTEM 28/40 patients (70%) and in FIBTEM 29/40 patients (72.5%)]; however, this hypercoagulable state persists in the first five days, but it decreases ten day after, without returning to normal values. No sign of secondary hyperfibrinolysis or sepsis induced coagulopathy (SIC) were found during the study period. In six patients (15%) a deep vein thrombosis and in 2 patients (5%) a thromboembolic event, were found; 12 patients (30%) had a catheter-related thrombosis. ROTEM analysis confirms that patients with severe COVID-19 pneumonia had a hypercoagulation state that persisted over time.

Background Critically ill COVID-19 patients have a clear pattern of inflammation and hypercoagulable state. The main aim of the study was to evaluate the outcome of severe COVID-19 patients basing on prothrombotic risk factors (i.e. D-dimer). We also evaluated the impact of different doses of low molecular weight heparin (LMWH) on the incidence of bleedings. Methods The data of forty-two patients admitted to the Intensive Care Unit (ICU) were retrospectively analyzed. On ICU admission, patients with D-dimer < 3000 ng/mL (Group 1) received enoxaparin 4000 UI (6000 UI, if body mass index >35) subcutaneously b.i.d. and patients with D-dimer ≥ 3000 ng/mL (Group 2) received enoxaparin 100 UI/kg every 12 h. Aspirin was administered to all patients once a day. Results Both groups presented a high incidence of perivascular thrombosis (40.9% in Group 1 and 30% in Group 2). Patients of Group 2 suffered a higher incidence of venous thromboembolism (VTE) than Group 1 (65% vs 13.6%, p = 0.001). One patient (4.5%) of Group 1 and three patients (15%) of Group 2 suffered from minor bleeding; no patient had major bleeding. Group 2 had a longer ICU and hospital stay than Group 1 (11.5 ± 5.6 vs 9.0 ± 4.8 and 30 ± 4.9 vs 21 ± 2.3, p < 0.05, respectively) as well as increased ICU mortality (25% vs 9.1%). Conclusions More severe critically ill COVID-19 patients have a high incidence of VTE and worse outcome, despite the use of heparin at the therapeutic dose. However, the use of heparin did not increase the incidence of bleeding complications.

Objectives: to identify reasons for re-hospitalization, assess nutritional status of elderly hospitalized patients using a validated nutritional assessment tool and analyze which factors are associated with readmission within the last year after discharge from index hospitalization for elderly hospitalized patients including nutritional related factors. Methodology: A cross-sectional study design was conducted in the internal medicine wards of Menoufia university hospital. All patients over 65 years of age within the first 72 hours of admission were eligible for the study. 162 patients were recruited with (93.6%) response rate. Data being collected using a structured questionnaire includes patients' sociodemographic, admission characteristics, severity of chronic disease using Cumulative Illness Rating Scale (CIRS) for geriatric. Assessment of nutrition status was performed using Mini Nutritional Assessment (MNA) tool and anthropometric measurements. Results: readmission within one year was found among (46.3%) of elderly participants. Relapse of initial condition was the most common reason (42.7%) followed by complications (24%). Half of readmitted group was malnourished and nearly one third at risk of malnutrition. Logistic regression identified strong association of hospital readmission with advanced old age ,smoking habit , poor dietary compliance , assistance needed feeding pattern ,severity of chronic disease ,comorbidities and lower MNA score Conclusion : Factors associated with readmission in elderly patients are multiple and complex. Malnourished elderly patients with cardiac , respiratory disease or diabetic with complex medical and social needs who are severely ill , with advanced age, smoker , who not compel well with dietary advice ,need assistance with feeding are tend to be readmitted. Recommendations: Re-hospitalized elderly patients should be identified and targeted by follow up and post hospital care to reduce readmissions.

Systemic coagulation abnormalities including clotting activation and inhibition of anticoagulant factors have been observed in patients with pneumonia. In severe coronavirus disease 2019 (COVID-19) the alteration of coagulation parameters was associated with poor prognosis. We evaluated the difference in coagulopathy between critically ill patients with COVID-19 pneumonia (COVID group) and non-COVID-19 pneumonia (non-COVID group), using traditional coagulation markers and rotational thromboelastometry (ROTEM). Standard laboratory and ROTEM parameters were evaluated in 45 patients (20 COVID group patients and 25 non-COVID group patients) at time of admission to the Intensive Care Unit (ICU) (T0) and at 5 (T5) and 10 days (T10) later. In all evaluations times, platelet count was found higher in COVID group rather than in non-COVID group. At T0, COVID group revealed a fibrinogen value greater than non-COVID group. d-Dimer values were high in both groups and they were not statistically different. At T0 COVID group showed a significant reduction of clot formation time in INTEM and in EXTEM and a significant increase of maximum clot firmness in INTEM, EXTEM and FIBTEM respect to non-COVID group. Moreover, COVID group demonstrated a coagulability state with ROTEM profiles higher than non-COVID group at T5 and T10. Coagulation profiles showed that critically ill patients with COVID-19 pneumonia are characterized by a higher coagulable state than others; this greater procoagulative state persists over time.
