In a small number of patients, infusions of unirradiated donor leukocytes were an effective treatment for EBV-associated lymphoproliferative disease that arose after allogeneic bone marrow transplantation.
Ganciclovir, when combined with high-dose intravenous immune globulin, appears to have significantly altered the outcome of patients with cytomegalovirus pneumonia after allogeneic bone marrow transplantation.
This paper examines the value relevance of earnings components where there is a mandatory requirement to report generally accepted accounting principles (GAAP) earnings and non-GAAP earnings, and where the items to be eliminated from GAAP earnings are defined in detail. The setting is different from non-GAAP earnings disclosures presented in the United States and elsewhere, where managers have discretion over whether to report a non-GAAP earnings number, and what to exclude from GAAP earnings. Our mandatory setting enables us to report value relevance results that are not confounded by managers' discretionary choices regarding non-GAAP earnings exclusions.We use price-level regressions, based on the Ohlson (1995) model, to test for incremental and relative value relevance. The results show that non-GAAP earnings reported under a mandatory regime have higher value relevance than GAAP earnings. The disaggregation of these items is useful to investors in a setting where managerial motivations are minimized.
Epstein-Barr virus–induced lymphoproliferative disease (EBV-LPD) is a serious and potentially fatal complication after allogeneic stem cell transplantation (SCT). To evaluate levels of EBV DNA in SCT patients, a semiquantitative polymerase chain reaction (PCR) assay was developed. DNA was extracted from peripheral blood leukocytes and diluted, and PCR was performed by using a primer set specific for a well-conserved sequence of the internal repeat 1 region of the EBV genome. Forty-one SCT patients were screened with this method. Thirty-seven patients received allogeneic transplants, of which 18 were T-cell–depleted marrow. Four additional patients received autologous SCT, one of which was T-cell depleted. The mean time of follow-up by EBV PCR was 147 days (range, 47 to 328 days) posttransplant. The range of EBV copies/μg DNA from normal EBV sero-positive donors was 40 to 4,000. Seven patients had ≥40,000 copies of EBV DNA/μg DNA, all of whom were recipients of T-cell–depleted SCT. Five of the seven patients with elevated levels of EBV DNA developed EBV-LPD. Four of these five patients with EBV-LPD had elevated levels of EBV DNA from 1 to 8 weeks before diagnosis. Two patients with EBV-LPD had normal levels of EBV DNA, and two patients with ≥40,000 copies EBV/μg DNA did not develop EBV-LPD. In one patient, clinical resolution of disease correlated with a decrease in EBV DNA and an increase in the level of EBV-specific cytotoxic T-cell precursors. These data indicate that the measurement of EBV viral load with semiquantitative PCR is useful in detecting EBV-LPD in high-risk patients before the onset of clinical symptoms. Because not all patients with elevated levels of EBV DNA develop EBV-LPD, semiquantitative PCR results cannot substitute for clinical, radiographic, and pathological confirmation of this diagnosis.
SYNOPSIS
We examine the impact of IFRS adoption on the earnings quality of foreign firms cross-listed in the U.S. from countries that have already adopted IFRS on a mandatory basis. We use the cross-listed firms as surrogates for the U.S. firms so we can observe the effect of IFRS adoption in the U.S. We examine five measures of earnings quality related to discretionary accruals, target beating, earnings persistence, timely loss recognition, and the earnings response coefficient (ERC). To isolate the effect of IFRS adoption, we use a matched sample design where each cross-listed firm is matched to a U.S. firm. We find the difference in earnings quality from the pre- to post-IFRS period is not different for the cross-listed and matched firms when earnings quality is measured by absolute discretionary accruals, timely loss recognition, or a long-window ERC. However, for the incidence of small positive earnings and earnings persistence, we find significant difference-in-differences, indicating that IFRS adoption led to an improvement in earnings quality for cross-listed firms relative to the matched firms. Our results are slightly surprising since U.S. GAAP is generally viewed as high-quality standards with little room for improvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
