Prevalence of risk-drinking in critically ill patients, screened with carbohydrate-deficient transferrin and AUDIT-C score: A retrospective study.

Background Studies demonstrate that up to one-third of intensive care unit (ICU) admissions are directly or indirectly related to alcohol. Screening for alcohol use is not routine. This study examined the prevalence of elevated %CDT (carbohydrate-deficient transferrin) and above risk-level AUDIT-C (Alcohol Use Disorders Identification Test, Consumption) in patients admitted to ICU. Methods We conducted a retrospective analysis of clinical and laboratory data from a single ICU where %CDT and AUDIT-C were included in routine assessment. After excluding readmissions, 2532 adult patients from a 21-month period were included. Admission values of %CDT were available for 2049 patients, and AUDIT-C was available for 1617 patients. The association of %CDT and AUDIT-C with short- and long-term outcome was studied by using univariate and multivariate logistic regression analysis. Results %CDT was above the reference value in 23.7% (486/2048) of patients with available %CDT. Of patients with available AUDIT-C, 33% (544/1617) had a risk-level AUDIT-C score. Patients with a risk-level AUDIT-C score were significantly younger than those with a lower score (51 vs 64 years, P < .0001). Increased %CDT was associated with higher severity of illness. AUDIT-C was associated independently with increased risk of long-term mortality in multivariate analysis (P = .007). Conclusion One in three of ICU patients are risk-level alcohol users as measured with AUDIT-C score, and one in four are analysed with %CDT. The prevalence varies according to the method used and any method alone may be insufficient to detect risk-level consumption reliably. Editorial Comment Alcohol overconsumption is associated with need for ICU admission and with less favorable outcomes. Diagnosis of alcohol overconsumption though is problematic due to low sensitivity in screening. In a pilot study, a biomarker and a screening tool are compared. The finding is that multiple tools are needed to achieve an adequate sensitivity for detection.

[Anticoagulation for continuous renal replacement therapy in the intensive care unit: a comparison of dalteparin infusion with regional citrate anticoagulation]. / Antikoagulaatio jatkuvassa munuaisten korvaushoidossa: daltepariini-infuusion ja sitraatti-kalsiumtekniikan vertailu.

Continuous renal replacement therapy (CRRT) is used to treat severe acute kidney injury in intensive care units. The aim of this study was to compare two anticoagulation techniques in CRRT, the infusion of dalteparin and regional citrate-calcium anticoagulation, in terms of efficacy and safety. In a retrospective study, we analysed data on 77 dalteparin and 75 citrate-calcium treatment periods. The primary endpoint was the life span of the CRRT circuit. The use of regional anticoagulation with citrate and calcium resulted in a significantly longer CRRT circuit life span as compared to that achieved with dalteparin infusion.

Increased hyaluronan content and stromal cell CD44 associate with HER2 positivity and poor prognosis in human breast cancer.

Previous in vitro studies have suggested interactions between hyaluronan (HA), CD44 and HER2. We have studied the expression of HA and CD44 in a material of 278 breast cancer cases, half of which were HER2-positive. Intense stromal HA staining was associated with HER2 positivity, large tumor size, lymph node positivity, hormone receptor negativity, poor differentiation, a high body mass index, increased relapse rate and shortened overall survival. Among the 139 HER2-positive cases, the relapse rate was associated with the intensity of stromal HA staining as most of the relapses occurred in the cases with intense stromal HA staining. The presence of HA in the carcinoma cells was related to the frequency of relapses as none of the patients without HA in carcinoma cells experienced a relapse, whereas 33.3% of those with a high percentage of HA-positive carcinoma cells suffered a relapse. CD44 positivity in carcinoma cells was related to poor differentiation, postmenopausal status and triple negative breast carcinoma. CD44 positivity in stromal cells was associated with HER2 positivity, large tumor size, hormone receptor negativity, poor differentiation, increased relapse rate and shortened overall survival. The association between HER2 positivity and intense stromal HA staining indicates that HA could be one of the factors involved in the unfavorable outcome of HER2-positive patients. This study also suggests that HA in breast carcinoma cells and CD44 in stromal cells may have clinical significance.
