Romiplostim for therapy-related thrombocytopenia in pediatric malignancies.

Therapy-related thrombocytopenia (TRT), due to chemotherapy and/or radiation therapy, is common with pediatric cancer treatments, and it can result in dose reductions and therapy delays. Romiplostim, a thrombopoietin mimetic, is efficacious as a second-line treatment for immune thrombocytopenia in children and for TRT in adult cancer patients. However, there are no data for its use for TRT in children. We report a case series of five children treated for solid tumors where romiplostim was used without adverse effects to successfully resolve and prevent therapy-limiting refractory TRT. Prospective studies on this use of romiplostim are warranted.

Refractory cytopenias secondary to copper deficiency in children receiving exclusive jejunal nutrition.

Copper deficiency is a known cause of anemia and neutropenia that is easily remedied with copper supplementation. Copper is primarily absorbed in the stomach and proximal duodenum, so patients receiving enteral nutrition via methods that bypass this critical region may be at increased risk for copper deficiency. In pediatrics, postpyloric enteral feeding is increasingly utilized to overcome problems related to aspiration, severe reflux, poor gastric motility, and gastric outlet obstruction. However, little is known about the prevalence of copper deficiency in this population. We describe three pediatric patients receiving exclusive jejunal feeds who developed cytopenias secondary to copper deficiency.

The relationship between alcohol use, eating habits and weight change in college freshmen.

PURPOSE: This study aims to improve understanding of how alcohol consumption in college freshmen affects eating patterns before, during, and after drinking, as well as its relation to body weight change. METHODS: Two hundred eighty-two college freshmen (61% female; 59% Caucasian) completed measures of alcohol use, measured body mass index (BMI), and eating and activity habits before, during and following drinking episodes. Students were categorized by drinking status (non-drinker, low-risk, and moderate/high-risk) in order to explore group differences. RESULTS: Seventy-five percent of the sample reported past-month alcohol consumption, with 65% (N=134) of these categorized as "low-risk" drinkers and 35% (N=72) as "moderate-risk" drinkers. Moderate-risk drinkers were more likely than low-risk drinkers to report increases in appetite after drinking, with nearly half of students reporting overeating and making unhealthy food choices following drinking. Moderate-risk drinkers also demonstrated significant increases in 1st semester BMI change, relative to non-drinkers and low-risk drinkers. CONCLUSIONS: Eating patterns for a significant number of college students are altered before, during, and following drinking episodes, which related to change in freshman year BMI.

Mobile Application vs Paper Pictorial Blood Assessment Chart to Track Menses in Young Women: A Randomized Cross-over Design.

STUDY OBJECTIVE: Heavy menstrual bleeding is a common symptom reported by approximately 30% of women. The Pictorial Blood Assessment Chart (PBAC) score is often used to quantify severity of menstrual bleeding. However, the traditional PBAC paper diary might be subject to recall bias and compliance issues, especially in adolescents. We developed a mobile application (app) version of the PBAC score and evaluated patient satisfaction and compliance with app reporting vs paper reporting. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: This study was a randomized cross-over study of 25 postmenarchal female adolescents and young women ages 13-21 years. Participants agreed to track bleeding in 2 consecutive menstrual cycles and were randomized to use the PBAC paper diary or mobile app format first. At the end of each cycle, a satisfaction survey and system usability scale (app only) was used to assess the acceptability of the format used. RESULTS: Twenty-five participants had a median age of 15 years. Cross-over analysis showed that satisfaction level was significantly higher for the app (P < .001). Twenty of 25 (80%) participants preferred the app over the paper diary. For the app, 20 of 25 participants (80%) had high compliance for reporting bleeding, with a mean of 2 app entries per day. Participants' PBAC scores did not vary significantly between the paper diary (median, 95) and mobile app (median, 114). All paper diaries met definition for high compliance. There was no significant period or carryover effect. CONCLUSION: This study showed that a PBAC app compared with the paper diary was the preferred method of recording menstrual bleeding in adolescents and showed feasibility as a research data collection tool.

Patterns of von Willebrand Disease Screening in Girls and Adolescents With Heavy Menstrual Bleeding.

OBJECTIVE: To estimate the frequency of von Willebrand disease screening and factors that affect screening frequency in a national sample of girls and adolescents with heavy menstrual bleeding. METHODS: In this retrospective cohort study, we used a national claims database for privately and publicly insured patients between 2011 and 2013 for girls aged 10-17 years. Diagnostic criteria of heavy menstrual bleeding were the presence of one inpatient or two outpatient International Classification of Diseases, 9th Revision codes for heavy menstrual bleeding. We defined severe heavy menstrual bleeding as heavy menstrual bleeding plus an inpatient stay for menstrual bleeding, iron deficiency anemia, or blood transfusion. To assess whether patient- or facility-level characteristics affected screening, we performed logistic regression analysis including patient age, health care provider type seen at first visit for menorrhagia, patient residence in a metropolitan statistical area (proxy for urban vs rural inhabitance), and approximate travel time to the nearest hemophilia treatment center. RESULTS: We identified 23,888 postpubertal girls and adolescents with heavy menstrual bleeding (986 with severe heavy menstrual bleeding). Von Willebrand disease screening was performed in 8% of females with heavy menstrual bleeding and 16% with severe heavy menstrual bleeding. Younger age at diagnosis, commercial insurance, and living within a metropolitan statistical area were associated with higher screening rates. Patients who underwent testing for iron deficiency anemia had the highest likelihood of undergoing screening (odds ratio 7.08, 95% CI 6.32-7.93). Among patients living in a metropolitan statistical area, those 60 minutes or more from a hemophilia treatment center were less likely to undergo screening. CONCLUSION: Despite recommendations by the American College of Obstetricians and Gynecologists for more than 15 years, fewer than 20% of postpubertal girls and adolescents with heavy menstrual bleeding underwent screening for von Willebrand disease in this cohort. Increased clinician awareness and adherence to recommended screening recommendations may increase diagnosis of von Willebrand disease.
