Attorney Fees in Class Action Settlements: An Empirical Study

JOURNAL OF EMPIRICAL LEGAL STUDIES, Issue 1 2004
Theodore Eisenberg
Study of two comprehensive class action case data sets covering 1993,2002 shows that the amount of client recovery is overwhelmingly the most important determinant of the attorney fee award. Even in cases in which the courts engage in the lodestar calculation (the product of reasonable hours and a reasonable hourly rate), the client's recovery generally explains the pattern of awards better than the lodestar. Thus, the time and expense of a lodestar calculation may be wasteful. We also find no robust evidence that either recoveries for plaintiffs or fees of their attorneys increased over time. The mean fee award in common fund cases is well below the widely quoted one-third figure, constituting 21.9 percent of the recovery across all cases for a comprehensive data set of published cases. A scaling effect exists: fees constitute a lower percent of the client's recovery as the client's recovery increases. Fees are also correlated with risk: the presence of high risk is associated with a higher fee, while low-risk cases generate lower fees. Fees as a percent of class recovery were found to be higher in federal than state court. The presence of "soft" relief (such as injunctive relief or coupons) has no material effect on the fee, regardless of whether the soft relief was included in the quantified benefit for the class used as the basis for computing the attorney fee. The study also addresses costs and expenses. Like fees, these display significant scale effects. The article proposes a simple methodology by which courts can evaluate the reasonableness of fee requests. [source]

Prevalence of hepatitis C virus infection in thalassemia and haemodialysis patients in north Iran-Rasht

JOURNAL OF VIRAL HEPATITIS, Issue 5 2002
M. M. Ansar
summary.,Hepatitis C virus (HCV) seroprevalence and risk factors in north Iran were investigated in 105 thalassemia sufferers, 93 haemodialysis patients and 5976 blood donors by second generation ELISA. Our study showed that haemodialysis patients and thalassemia sufferers were at higher risk of having HCV infection; the prevalence being 55.9% and 63.8% respectively in comparison to the prevalence of blood donors (0.5%). A confirmatory immunoblotting was employed using HCV-positive cases (54 thalassemia sufferers and 19 blood donors). The result showed that 92.6% of samples of the first group and 10.5% of the latter were positive. Thus, it can be suggested that ELISA in low-risk cases may produce considerable false positives. In HCV-positive patients with thalassemia, the incidence of HCV among different age groups and genders was similar but a strong correlation in respect to the number of blood transfusion (P=0.008) was observed. In HCV-positive haemodialysis patients, it was found that there was no correlation with liver function tests (alanine aminotransferase and aspartate aminotransferase: ALT and AST), but a significant correlation was observed in respect to the duration of dialysis(P=0.000) and the number of units transfused (P=0.000). Consequently, it still seems blood transfusion is the main factor for increasing the incidence of HCV in thalassemia sufferers and haemodialysis patients. [source]

Correlation of enhanced cell turnover with prognosis of gastrointestinal stromal tumors of the stomach: Relevance of cellularity and p27Kip1

PATHOLOGY INTERNATIONAL, Issue 12 2006
Yuta Nemoto
The aim of the present study was to determine whether expression of molecules associated with cell cycle regulation and apoptosis might reflect tumor grade and patients' prognosis of gastrointestinal stromal tumor (GIST). Forty-nine cases of gastric GIST were divided into three grades; low, intermediate, and high risk. Ki-67, cyclin A, cyclin D1, cyclin E, p16Ink4, p21Waf1, p27Kip1, cyclin-dependent kinase (cdk)2, cdk4 and single-strand DNA (ssDNA) were immunohistochemically stained and assessed. Ki-67, ssDNA, cyclin A and cdk2 had higher labeling indices (LI) in high-risk than in low-risk cases. Cyclin E expression was greater in the intermediate- than in the low-risk grade. On Kaplan,Meier analysis, tumor size, necrosis, cellularity, Ki-67, ssDNA, and cyclin A LI were significantly correlated with disease-free survival. Necrosis, cellularity, and Ki-67 LI were significant as prognostic factors on univariate, and Ki-67 LI on multivariate Cox hazard tests. Within the high-risk grade, high cellularity and low p27Kip1 subgroups had the worst prognosis. The histological grade is related to cell turnover, assessed in terms of Ki-67, ssDNA, cyclin A, cyclin E, and cdk2 levels. Ki-67, ssDNA, and cyclin A are useful for prediction of prognosis, with cellularity and p27Kip1 expression as further prognostic factors in high-risk cases. [source]

Evidence-based prescription of antibiotics in urology: a 5-year review of microbiology

BJU INTERNATIONAL, Issue 6 2009
Ranan DasGupta
OBJECTIVE To analyse the results of positive urine cultures over a 5-year period in a large hospital and urology department (amongst both inpatients and outpatients), assess the prevalence of different organisms and the resistance profiles of a range of antibiotics, and thus provide information on which organisms are likely to cause urosepsis. METHODS The use of antibiotics should be based on knowledge of which pathogens are present and what resistance patterns are emerging, particularly relevant in surgical disciplines like urology, as antibiotics are now routinely administered peri-operatively, whereby evidence-based prescription is preferable to generic guidelines. We therefore examined almost 25 000 positive urine cultures in our hospital over a 5-year period, and focused on the infections encountered amongst urology patients during this time. RESULTS A significant proportion of inpatient urinary infection (40%) is caused by Gram-positive bacteria such as Streptococcus faecalis, underlining the need for including Gram-positive cover during urological prophylaxis. The commonest pathogen remains Escherichia coli among both inpatients and outpatients. The ineffectiveness of common antibiotics such as ciprofloxacin and trimethoprim was identified, as was the increase in gentamicin resistance. CONCLUSION We propose using an aminoglycoside with a penicillin for high-risk cases (e.g. endoscopic stone surgery) while low-risk cases (e.g. flexible cystoscopy with no risk factors) might be managed without such prophylaxis. Pathogenic patterns and resistance rates should be monitored regularly. [source]
