The outcome measures for loss of functionality in the activities of daily living of adults after stroke: a systematic review

Objective: To provide clinicians and researchers information regarding (1) the existing outcome measures to assess the loss of functionality in the activities of daily living (ADLs) of patients with stroke and (2) the presence of these assessment tools in the Italian context.

Study Design and Setting: For this Systematic Review Medline, CINAHL, and PsycINFO were searched for articles published up to 4 July 2017. Two authors independently identified eligible studies on the basis of prede?ned inclusion criteria and extracted data. Study quality and risk of bias were assessed using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.

Results: Of 370 publications identified and screened, 46 studies fell within the inclusion criteria and were critically reviewed. The most commonly used tools were: the Frenchay Activities Index and the Functional Independence Measure.

Conclusion: This review has emphasized the need for agreement among researchers as to which tool must be studied in depth or adapted to other national contexts in order to develop universal norms and standards.     

Erythropoietin production and erythropoiesis in compensated and anaemic states of hereditary spherocytosis

A compensated haemolytic state is defined by decreased red cell life-span without anaemia, i.e. by increased erythropoiesis in the absence of the physiological stimulus for erythropoietin (Epo) production. We evaluated s-Epo levels and the expansion of erythropoiesis (as measured by circulating transferrin receptor, s-TfR) in 32 patients with hereditary spherocytosis (HS) with the aim of verifying whether the enhanced erythropoiesis of compensated haemolysis was Epo-dependent. 20 of the patients (62.5%) had normal Hb values (> 12 g/dl in females and > 13 g/dl in males). Their compensated haemolytic state was the result of up to 8.2 times normal s-Epo and up to 3.9 times normal s-TfR levels, which were maintained by physiological regulation of erythropoiesis, as documented by the inverse dependence of Hb on s-Epo levels. Considering that patients with iron-deficiency anaemia represented the predicted physiological Epo response to anaemia, the observed/predicted ln s-Epo ratio (O/P ratio) was calculated in HS patients with anaemia and was used as an index of the adequateness of Epo production. All the anaemic HS patients had an O/P ratio > 1, documenting inappropriately high s-Epo levels. This work demonstrates that the compensated haemolytic state of HS patients is produced by an inappropriately high s-Epo level, and that the pattern of Epo overproduction is a biological characteristic of the disease.     

Comparison of Direct Interview and Family History Diagnoses of Alcohol Dependence

Using data from The Collaborative Study on the Genetics of Alcoholism, we compare direct interview diagnoses of alcohol dependence to those obtained by history from family members. Using a requirement of three or more positive implications by history, the specificity, sensitivity, and positive predictive values are 98%, 39%, and 45%, respectively.
A logistic analysis found the gender of the relative and alcoholism in the informant to be significant, but not the gender of the informant. The partial odds ratio of a diagnosis at interview associated with a positive family history diagnosis was 13.6. The relationship between the informant and relative was significant, with negative reports from an offspring or mate more influential than a negative report from a parent or second-degree relative.
We derived a recursive equation to combine a variable number of family history reports, wherein the probabilities associated with a single report are computed from the logistic analysis. This permits the use of family history information both as a proxy for an uninterviewed relative, as well as a second source of information to be used in the analysis of genetic family data.     

Transcatheter arterial chemoembolization (TACE) in treatment of hepatocellular carcinoma

BACKGROUND/AIMS: Substantial differences about the efficacy of transcatheter arterial chemoembolization for the treatment of hepatocellular carcinoma are reported in literature. This probably depends on the fact that in each single study, different patient selection criteria, type of epidemiological approach, end points adopted and kind of technical approach were used. This study aims to evaluate the efficacy of segmental transcatheter arterial chemoembolization in amelioring patient survival and to determine which patients might really benefit from this treatment. METHODOLOGY: To achieve our goals 193 consecutive patients (110 treated and 83 untreated) were studied. They were selected in the same period of time and matched as far as their demographic and clinical characteristics. RESULTS: Our results demonstrate that both in treated and control patients, Child class, alpha-fetoprotein and tumor diameter significantly influenced survival, resulting important prognostic factors. Transcatheter arterial chemoembolization significantly ameliorated survival in treated patients compared to controls (p < 0.0001). CONCLUSIONS: Transcatheter arterial chemoembolization significantly ameliorates survival in patients with hepatocellular carcinoma. However, the presence of large tumors producing high alpha-fetoprotein levels in patients with advanced Child class should discourage treatment.
