BACKGROUND The Stanford group has reported excellent results with the Stanford V regimen for patients with bulky and/or advanced Hodgkin lymphoma (HL). However, Gobbi reported markedly inferior failure-free survival (FFS) comparing Stanford V to other regimens but included major deviations from the original program. We retrospectively examined whether treatment at our institution carefully foll...

cept can serve as a basis for identifying subgroups that are in need of programmatic action. Unmet need rises as more women would like to control their fertility but for various reasons are unable to do so, and it falls as more start practicing contraception. However, high levels of unmet need in a country do not necessarily reflect program failure, nor do low levels always indicate program suc...

BACKGROUND Two of the most common types of health care delivery systems in the U.S. are fee-for-service (FFS) and managed care systems such as health maintenance organizations (HMO). Differences may exist in patient outcomes depending on the health care delivery system in which they are enrolled. We evaluated differences in the survival of patients with breast and colorectal cancer at diagnosis...

OBJECTIVE To evaluate differences in the stage at diagnosis and survival for melanoma between the 2 most common types of Medicare health care delivery systems, fee-for-service (FFS) and managed care (health maintenance organizations [HMOs]), in the United States during the period from January 1, 1985, through December 31, 1994. DESIGN We used a linkage of 2 national databases, ie, the Medicar...

The gold standard endpoint in trials of locoregionally advanced nasopharyngeal carcinoma (NPC) is overall survival (OS). Using data from a phase III randomized trial, we evaluated whether progression-free survival (PFS), failure-free survival (FFS), distant failure-free survival (D-FFS) or locoregional failure-free survival (LR-FFS) could be reliable surrogate endpoints for OS. Between July 200...

BACKGROUND This study examined the association between the physical work environment and physiological performance measures, physical activity levels and metabolic parameters among German civil servants. A main focus in this study was to examine the group differences rather than measuring the absolute values in an occupational group. METHODS We prospectively examined 198 male German civil ser...

Running research has focused on reducing injuries by changing running technique. One proposed method is to change from rearfoot striking (RFS) to forefoot striking (FFS) because FFS is thought to be a more natural running pattern that may reduce loading and injury risk. Muscle activity affects loading and influences running patterns; however, the differences in muscle activity between natural F...

The main objective of this study was to assess the impact of farmer field schools on adoption of technical packages of wheat production in Gezira Scheme, Sudan. Field survey was used to collect data from 50 FFS-participants of two schools (25 from each school), and also equal number from Non-FFS participants were selected for comparison. Close ended questionnaire was used in data collection. Th...

Background It is reported that 75% of long distance runners use a rearfoot strike (RFS) technique. This percentage decreases in faster runners, where the incidence of midfoot and forefoot strikers (FFS) increases [1]. It is possible that FFS better utilises the passive-elastic mechanisms of the lower limb reducing energy cost. Williams et al. [2] found runners who converted from RFS to FFS duri...

OBJECTIVE In this study, we evaluated used aluminum tuning forks (TFs) for fundamental frequencies (FF), overtones, and decay times. MATERIALS AND METHODS In total, 15 used (1 C1, 11 C2, and 3 C3) and 1 unused (C2) TFs were tuned, and the recorded sound data were analyzed using the Praat sound analysis program. RESULTS It was found that FFs of the recorded sounds produced by the used C2-TFs...
