BACKGROUND Older patients with aneurysmal subarachnoid hemorrhage (aSAH) are unique, and determinants of post-acute care outcomes are not well elucidated. The primary objective was to identify hospital characteristics associated with 30-day readmission and mortality rates after hospital discharge among older patients with aSAH. METHODS AND RESULTS This cohort study used Medicare patients ≥65 ...

A review of the literature that has appeared over the past five decades indicates that the median case fatality from severe malnutrition has remained unchanged over this period and is typically 20-30%, with the highest levels (50-60%) being among those with oedematous malnutrition. A likely cause of this continuing high mortality is faulty case-management. A survey of treatment centres worldwid...

We derive a generalized Balitskii-Fadin-Kuraev-Lipatov equation, which applies directly to the perturbative QCD component of total cross section. With the gluon correlation radius Rc ∼ 0.4fm we reproduce the empirical rate of growth of the hadron-nucleon total cross sections. The simultaneous estimate of the triple-pomeron coupling also agrees with the experiment. To be published in: JETP Lette...

Abeysinghe (Economic Letters, 1991, 36, 175-197; Journal of Econometrics, 1994, forthcoming) showed that seasonal dummies in regressions may lead to spurious inference. This paper evaluates the post-sample forecasting performance of a seasonal-dummy ARIMA model with four other models. The results, in general, do not stand in favor of the seasonal-dummy approach. JEL classification: C53

Nova Scotia, and especially Cape Breton, has high cervical cancer incidence and mortality rates. Letters were sent to 15,691 unscreened and 6,995 under-screened women from Cape Breton Island encouraging them to obtain a Pap test. Controls were 61,510 unscreened women and 32,996 under- screened women in mainland Nova Scotia who were not sent letters. For this cohort study, the provincial Health ...

BACKGROUND Early fluid resuscitation is vital to patients with sepsis. However, the choice of fluid has been a hot topic of discussion. The objective of this study was to evaluate whether the use of albumin-containing fluids for resuscitation in patients with sepsis was associated with a decreased mortality rate. METHODS We systematically searched PubMed, EMBASE and Cochrane library for eligi...

A descriptive retrospective study of acute intoxication cases registered at the Complexo Hospitalario de Pontevedra (CHOP) between January 2005 and December 2008 was performed to find out the number and types of poisoning cases treated, their distribution according to patient's sex and age, chronology, type of toxic agents involved, intentionality, history, symptoms, clinical development, treat...

OBJECTIVES To describe the content of non-public complete response letters issued by the US Food and Drug Administration (FDA) when they do not approve marketing applications from sponsors (drug companies) and to compare them with the content any subsequent press releases issued by those sponsors DESIGN Cross sectional study. DATA SOURCES All applications for which FDA's Center for Drug Eva...

BACKGROUND Persons being treated with IFNalpha-2b for advanced cutaneous malignant melanoma (CMM) have been reported to have a greatly improved prognosis if they develop autoantibodies or clinical signs of autoimmunity during therapy. Consequently, we examined whether autoimmune diseases might also be associated with lower CMM incidence and better prognosis. METHODS We established a study coh...
