Interstitial pneumonitis in acute leukemia patients submitted to T-depleted matched and mismatched bone marrow transplantation.
No full textPURPOSE:
To identify factors that could contribute to interstitial pneumonitis (IP), which remains one of the major causes of morbidity and mortality after both matched and mismatched bone marrow transplantation (BMT).
METHODS AND PATIENTS:
Ninety acute leukemia patients received an allogeneic T-depleted matched (n = 54) or mismatched (n = 36) BMT. They were preconditioned with total body irradiation (TBI), thiotepa, rabbit anti-thymocyte globulin, and cyclophosphamide. The TBI scheme was hyperfractionated in matched, and a single dose in mismatched patients. The dose to the lungs was reduced in both groups.
RESULTS:
Five of the 54 matched patients developed IP. All cases were fatal. There were 16 cases of IP, 13 fatal, in the mismatched group. The probability of developing IP was 11.3 +/- 4.9% and 48.6 +/- 9.0%, respectively. The between-group difference was statistically significant (p < 0.0001). The type of transplant and the TBI scheme were the most important parameters for IP development in univariate analysis, whereas acute graft-versus-host disease, disease stage and sex were nonsignificant. Median follow-up was 342 days (range 17-2900).
CONCLUSIONS:
The low incidence of IP in matched patients and the lack of idiopathic cases are evidence for the validity of the TBI schedule. In contrast, the incidence in mismatched patients remains too high; therefore, new strategies should be studied in an attempt to lower it
Hepatitis B, C and Delta virus infections in Albanian patients with chronic liver disease: evaluation of possible changes during the last 10 years
No full textObjective and methods The prevalence of viral hepatitis markers and of alcohol intake was evaluated in 106 and 99 Albanian patients with the diagnosis of viral and/or alcoholic chronic liver disease who were consecutively admitted to the University Hospital Center of Tirana, during 1995 and 2005, respectively. Results A slight decrease in HBsAg (78 vs. 70%) and HBeAg (18 vs. 12%) prevalences were observed in patients admitted to the hospital during 2005 compared with those admitted during 1995, respectively. In both periods of time, hepatitis B virus (HBV) DNA (genotype D) tested positive in all HBsAg-positive patients and in 36% of HBsAg-negative patients. Anti-hepatitis C virus (HCV) prevalence (mainly observed after 30 years of age) was 14 versus 11 %; anti-hepatitis Delta virus (HDV) prevalence (more frequently present in young age group patients) was 9 versus 7% during 1995 and 2005, respectively. Among patients who reported alcohol intake, alcoholic liver disease (HBsAg and anti-HCV negative) was diagnosed in 35 and in 57% of patients admitted during 1995 and 2005, respectively (P=0.05). Conclusion In Albanian patients with chronic liver disease, we have found that: (i) HBV remained the most important aetiologic factor of chronic liver disease; HDV and HCV prevalences were still low, (ii) in HBsAg-positive patients, HBeAg-negative chronic hepatitis prevailed, (iii) in HBsAg-negative patients, HBV DNA prevalence was high, (iv) during the last decade, an increased prevalence of alcohol intake in the aetiology of chronic liver disease was observed.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
