- A total of 123 balanced rearrangements, including 26 occurring as a sole anomaly, not known to be recurrent in myelodysplastic syndromes (MDS) or acute myelold leukemia (AML) prior to the Workshop, were ascertained retrospectively from 104 patients with treatment-related MDS/AML (t-MDS/t-AML). Thirteen of the aberrations were reported previously in single cases and hence may be classified as recurrent as a result of the Workshop. Patients with Unique aberrations had complex karyotypes more often (P < 0.001 for all pairwise comparisons) than did other Workshop subgroups, with 72% having 3 or more aberrations. Among 85 cases with secondary chromosomal abnormalities, -5, -7, del(5q), and del(7q) were observed in 76%, which is significantly higher (P less than or equal to 0.007 for all pairwise comparisons) than the frequencies found in the Workshop subgroups of patients with previously known recurring aberrations. The chromosome bands most often involved in balanced aberrations were 1p36 and 3q26-27. Treatment exposure was significantly different (less topoisomerase 11 inhibitor exposure, more radiotherapy-only exposure) than for patients with 11q23 (P < 0.001 and P = 0.002, respectively) and 21q22 (P = 0.007 and P = 0.002, respectively) abnormalities. The median time from the first toxic exposure to secondary disease, 59 months, was significantly longer (P less than or equal to 0.016 for all significant pairwise comparisons) than the median latency of all other patients except those in the Rare subgroup, and the median survival time, 7 months, was significantly shorter than for patients in the 21q22, inv(16), and t(15; 17) subgroups (P less than or equal to 0.002 for all pairwise comparisons), but similar to patients in the 11q23 and Rare subgroups. In contrast to known recurring abnormalities, significantly more patients (61%, all P < 0.001) presented with t-MDS, with over one-third of these patients progressing to t-AML. Thus, this group of patients appears to be more similar to the typical t-MDS/t-AML patients, with complex karyotypes as well as chromosome 5 and 7 abnormalities, than to those with recurrent balanced rearrangements.

- Background:The goal of this study was to establish preliminary criterion-referenced cut points for adult pedometer-determined physical activity (PA) related to weight status defined by body mass index (BMI).Methods:Researchers contributed directly measured BMI and pedometer data that had been collected (1) using a Yamax-manufactured pedometer, (2) for a minimum of 3 days, (3) on ostensibly healthy adults. The contrasting groups method was used to identify age- and gender-specific cut points for steps/d related to BMI cut points for normal weight and overweight/obesity (defined as BMI <25 and ≥25 kg/m2, respectively).Results:Data included 3127 individuals age 18 to 94 years (976 men, age = 46.8 ± 15.4 years, BMI = 27.3 ± 4.9; 2151 women, age = 47.4 ± 14.9 years, BMI = 27.6 ± 6.4; all gender differences NS). Best estimated cut points for normal versus overweight/obesity ranged from 11,000 to 12,000 steps/d for men and 8000 to 12,000 steps/d for women (consistently higher for younger age groups).Conclusions:These steps/d cut points can be used to identify individuals at risk, or the proportion of adults achieving or falling short of set cut points can be reported and compared between populations. Cut points can also be used to set intervention goals, and they can be referred to when evaluating program impact, as well as environmental and policy changes.
