RESUMO
Objective:To examine the significance of serum Endocan levels in evaluating the severity of disease and predicting the prognosis for elderly patients with multiple organ dysfunction syndrome(MODS).Methods:Seventy-five elderly patients from the Department of Geriatric ICU at the First Affiliated Hospital of Nanjing Medical University were selected and divided into two groups: the non-MODS group and the MODS group.This division was based on the levels of acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)scores and MODS scores within 24 hours of admission.Additionally, 40 elderly individuals undergoing physical examination were included as a control group.Venous blood samples were collected from all participants to detect the levels of Endocan using ELISA.The patients were further categorized into the survival group and the death group based on their clinical outcome within 28 days.The Endocan levels in all groups were compared, and receiver operating characteristic(ROC)curves were generated to assess the value of Endocan in determining the severity of the disease and predicting prognosis in elderly MODS patients.Results:The levels of Endocan were found to be higher in the MODS group compared to the non-MODS and control groups[(622.3±149.2)ng/L vs.(433.1±189.7)ng/L, P<0.001]. Furthermore, patients with higher APACHE Ⅱ and MODS scores exhibited higher levels of Endocan.The area under the ROC curve(AUC)for Endocan, MODS score, and Endocan+ MODS score were 0.791, 0.806, and 0.820, respectively( P>0.05). Similarly, the AUC for Endocan, APACHE Ⅱ score, and Endocan+ APACHE Ⅱ score were 0.763, 0.799, and 0.803, respectively( P>0.05). Interestingly, the survival group had lower levels of Endocan compared to the death group[(444.6±193.6)ng/L vs.(618.2±149.5)ng/L, P<0.001]. Conclusions:Endocan can be utilized as a noteworthy indicator, which is associated with the seriousness of illness and the prognosis for elderly patients with multiple organ dysfunction syndrome(MODS).

RESUMO
Objective To investigate the prevalence of nutritional risk,undernutrition and nutritional support among elderly inpatients with coronary heart disease in 11 tertiary A hospitals in China.Methods Records of elderly patients under the age of 90 with coronary heart disease were collected between March 2012 and May 2012 from 11 tertiary A hospitals in China following the direction of diagnosis related group of Beijing government.Results A total of 1 279 consecutive cases were recruited with the average age 74 years old (65-89).The total nutritional risk prevalence was 28.14％ (360/1 279).The prevalence of nutritional risk and nutritional risk score ≥ 5 increased with age.The prevalence of nutritional risk (12.88％ vs.30.08％ vs.42.28％) and nutritional risk scored ≥5 (10.86％ vs.18.61％ vs.27.78％)increased with age.Judging from BMI,most patients were overweight or obese (BMI ≥ 24 kg/m2),accounting for 53.0％ of the total,and prevalence of nutritional risk in this subgroup was 15.12％ (96/635).The prevalence of nutritional risk in patients with normal BMI was 34.24％.The prevalence of undernutrition defined as BMI＜ 18.5 kg/m2 was 4.25％ (51/1 279),among which patients with score ≥ 5 account for 64.7％ (33/51).The prevalence of undernutrition defined as nutritional impairment score =3 was 7.58％ (97/1 279).In patients with nutritional risk,57 were administrated nutrition support (16.6％);in patients without nutritional risk,21 received nutrition support,mostly parenteral nutrition (16 cases,76.2％).In patients with nutritional risk [(79.46± 7.19) years vs.(76.40± 6.16) years],there were statistically significant difference between those who received nutrition support and those who did not in terms of age and the ratio of patients with nutritional risk scored≥5 (35.1％ vs.17.1％) (P =0.001,P=0.002).Conclusions The prevalence of nutritional risk in patients with coronary heart disease was high.The prevalence of undernutrition was low.Prevalence of overweight and obese was high,but there was still nutritional risk in this group of patients.The patients who received nutrition support were older and had high nutritional impairment score,but the indication is not rationale.
RESUMO
Objective To study the efficacy of linezolid on gram positive bacterial infection in elderly patients and risk factors associated with thrombocytopenia.Methods A retrospective analysis of 50 elderly patients treated with intravenous linezolid for gram-positive bacterial infection from January 2008 to October 2010 was conducted.Clinical data and bacteriological responses were assessed.Efficacy of linezolid on infection and risk factors associated with thrombocytopenia in elderly patients were analyzed.Results The average duration of treatment was (13±2) d,the efficacy rate was 74 ％ and the bacteriological eradication rate was 69 ％ (18/26).Thrombocytopenia occurred in 24 patients during the treatment,and the average platelet count was significantly reduced compared with pretreatment[(146±87) 109/L vs.(239± 114) 109/L,t=3.888,P=0.000)].Thromhocytopenia was associated with the baseline platelet count and the mean time of linezolid treatment.Based on a Logistic regression analysis,the baseline platelet count ＜ 200 × 109/L was identified as the only significant risk factor for linezolid-associated thrombocytopenia in elderly patients (OR =0.244,95％CI:0.068-0.874,P=0.030).The mean platelet count was decreased significantly after 7 days of treatment,and decreased to the lowest value 1-2 days after the end of therapy.Conclusions Linezolid is effective and safe for the elderly with gram-positive bacterial infection,especially hospital acquired methicillin-resistant staphylococcus aureus infection.Linezolid has little effect on liver and renal function in elderly patients,but it can cause thrombocytopenia,which is associated with baseline platelet count and the mean time of linezolid treatment.Platelet counts should be monitored during treatment and measures should be taken to prevent hemorrhagic tendencies.
