Efficacy and toxicity of concomitant cisplatin with external beam pelvic radiotherapy and two high-dose-rate brachytherapy insertions for the treatment of locally advanced cervical cancer

OBJECTIVE: There is no standard high-dose-rate (HDR) brachytherapy dose for locally advanced cervical cancer. The objective of this study was to determine the efficacy, toxicity and clinicopathologic predictive markers affecting survival using cisplatin (CDDP) concomitant with external beam pelvic radiotherapy (EBRT) and two 9-Gy HDR insertions for the treatment of locally advanced cervical cancer. METHODS: 77 consecutive patients with Stage IB2-IV cervical cancer treated with CDDP, EBRT and two 9-Gy HDR insertions were included. Kaplan-Meier methods and Cox proportional hazards models were applied for survival statistics. RESULTS: Median age was 53. 90% had squamous cell carcinoma. Median follow-up time was 3.5 years (range 0.5-12 years). Overall 5-year progression-free survival (PFS) was 75%. Local control rate and 5-year PFS were 88% and 83%, respectively, for Stages IB2/II, and 68% and 61%, respectively, for Stages III/IV. Grade 3/4 GI symptoms were the most common acute side effects (47%). Grade 3/4 late toxicities occurred in five (6%) patients. CONCLUSIONS: HDR brachytherapy regimens consisting of two 9-Gy HDR insertions have similar efficacy and side effect profiles as other brachytherapy regimens for the treatment of cervical cancer with improved safety and patient convenience.     

Baseline Results from Hawaii's Nā Mikimiki Project: A Physical Activity Intervention Tailored to Multiethnic Postpartum Women

During the postpartum period, ethnic minority women have higher rates of inactivity/under-activity than white women. The Nā Mikimiki (“the active ones”) Project is designed to increase moderate-to-vigorous physical activity over 18 months among multiethnic women with infants 2–12 months old. The study was designed to test, via a randomized controlled trial, the effectiveness of a tailored telephone counseling of moderate-to-vigorous physical activity intervention compared to a print/website materials-only condition. Healthy, underactive women (mean age = 32 ± 5.6 years) with a baby (mean age = 5.7 ± 2.8 months) were enrolled from 2008–2009 (N = 278). Of the total sample, 84% were ethnic minority women, predominantly Asian–American and Native Hawaiian. Mean self-reported baseline level of moderate-to-vigorous physical activity was 40 minutes/week with no significant differences by study condition, ethnicity, infant's age, maternal body mass index, or maternal employment. Women had high scores on perceived benefits, self-efficacy, and environmental support for exercise but low scores on social support for exercise. This multiethnic sample's demographic and psychosocial characteristics and their perceived barriers to exercise were comparable to previous physical activity studies conducted largely with white postpartum women. The Nā Mikimiki Project's innovative tailored technology-based intervention and unique population are significant contributions to the literature on moderate-to-vigorous physical activity in postpartum women.     

Copper deficiency in rats: the effect of type of dietary protein.

The present investigation was conducted to determine whether type of dietary protein can exacerbate the pathology induced by the combination of fructose feeding and copper (Cu) deficiency. Weanling male Sprague-Dawley rats were assigned to three different groups differing in the nature of dietary protein. The proteins used were egg-white, casein or lactalbumin. All diets contained 62.5% carbohydrate as fructose and were low in Cu (0.6-0.72 microgram Cu/g diet). Although the lowest concentration of Cu was found in the livers of rats fed egg-white, the pathology associated with Cu deficiency was more severe in rats fed lactalbumin. The highest concentration of hepatic Cu was found in rats fed casein. The data show that the type of dietary protein can exacerbate signs associated with Cu deficiency. The concentrations of hepatic Cu do not reflect accurately the pathology associated with Cu deficiency.     

Pre-morbid human T-lymphotropic virus type I proviral load,rather than percentage of abnormal lymphocytes,is associated with an increased risk of aggressive adult T-cell leukemia/lymphoma

Out of 153 newly referred human T-lymphotropic virus type I infected patients, 42 (27%) had 5% or more abnormal lymphocytes, consistent with the diagnosis of smoldering adult T-cell leukemia/lymphoma. The abnormal lymphocyte percentage was higher in patients with human T-lymphotropic virus type I associated inflammatory disease compared with asymptomatic carriers (P=0.006). Over 4.5 years median follow up, 4 patients, all with 10 or more human T-lymphotropic virus type I DNA copies/100 peripheral blood mononuclear cells at presentation, but only one with 5% or more abnormal lymphocytes at presentation, developed adult T-cell leukemia/lymphoma. Thus, high pre-morbid human T-lymphotropic virus type I proviral load, rather than fulfilment of the classification criteria for smoldering adult T-cell leukemia/lymphoma, was associated with an increased risk of developing aggressive adult T-cell leukemia/lymphoma.
