Peritransplant eculizumab does not prevent delayed graft function in deceased donor kidney transplant recipients: Results of two randomized controlled pilot trials

Animal models and observational human data indicate that complement, including C5a, pathogenically participates in ischemia reperfusion (IR) injury that manifests as delayed graft function (DGF) following deceased donor kidney transplantation. We report on the safety/efficacy of anti‐C5 monoclonal antibody eculizumab (Ecu) administered in the operating room prior to reperfusion, to prevent DGF in recipients of deceased donor kidney transplants in two related, investigator‐sponsored, randomized controlled trials. Eight recipients from a single center were enrolled in a pilot study that led to a 19‐subject multicenter trial. Together, 27 deceased donor kidney transplant recipients, 16 Ecu‐treated and 11 controls, were treated with rabbit antithymocyte globulin, tacrolimus, mycophenolate mofetil with or without glucocorticoids, and followed for 6 months. Data analysis showed no epidemiological or transplant‐related differences between study arms. Ecu was well tolerated with a similar severe adverse event incidence between groups. The DGF rate did not differ between Ecu‐treated (44%) and control (45%, P = 1.0) subjects. Serum creatinine reduction in the first week after transplantation, and graft function up to 180‐days post‐transplant, were also similar. Ecu administration was safe but did not reduce the rate of DGF in a high‐risk population of deceased donor recipients.     

Feasibility of a Group-Based,Facilitator-Directed Online Family Lifestyle Program

ObjectiveThis study aimed to overcome barriers to access and attendance, and improve recruitment and engagement, through delivery and evaluation of the Parenting, Eating and Activity for Child Health (PEACH) child weight management program, as a facilitated group-based online healthy lifestyle program, PEACH Lifestyle.MethodsPre-post feasibility study of an online intervention comprising a website with 10 self-directed learning modules and 6 facilitated group-based video conferencing sessions with parents (n = 79) of children (7.9 ± 2.9 years, 25% healthy weight, 23% obese).ResultsThree enrollees were from remote locations. Half of the parents (n = 38) attended ≥1 video conferencing session (median = 3 participants per session [Range, 0–7]). Thirty percent (n = 7 of 21) completed all 10 online modules. Technical issues, time, and family commitments were barriers to engagement.Conclusions And ImplicationsReframing and delivering a weight management program as a healthy lifestyle program online in real-time did not address barriers to engagement in PEACH Lifestyle.     

Effects of reducing television viewing on children's requests for toys: a randomized controlled trial.

Previous attempts to reduce the effects of television advertising on children's purchase requests have had little success. Therefore, we tested the effects of a classroom intervention to reduce television, videotape, and video game use on children's toy purchase requests, in a school-based randomized controlled trial. Third- and fourth-grade children (mean age, 8.9 years) in two sociodemographically and scholastically matched public elementary schools were eligible to participate. Children in one randomly selected elementary school received an 18-lesson, 6-month classroom curriculum to reduce television, videotape, and video game use. In both schools, in September (before intervention) and April (after intervention) of a single school year, children and parents reported children's prior week's purchase requests for toys seen on television. After intervention, children in the intervention school were significantly less likely to report toy purchase requests than children in the control school, with adjusting for baseline purchase requests, gender, and age (odds ratio, 0.29; 95% confidence interval, 0.12-0.69). Among intervention school children, reductions in self-reported purchase requests were also associated with reductions in television viewing. There was no significant difference between schools in parent reports of children's requests for toy purchases. These findings suggest that reducing television viewing is a promising approach to reducing the influences of advertising on children's behavior.     

Pursuit of thinness and onset of eating disorder symptoms in a community sample of adolescent girls: A three-year prospective analysis

Community-based prospective studies are needed to shed light on mechanisms that may influence development of eating disorders and identify variables that could serve as potential targets for prevention efforts. In this paper we examine level of weight preoccupation and other variables prospectively associated with age of onset of eating disorder symptoms over a 3-year interval in a community sample (N = 939) of young adolescent girls. 3.6% (32/887) experienced onset of symptoms over the interval. Only one factor, a measure of Weight Concerns, was significantly associated with onset (p < 001). Girls scoring in the highest quartile on the measure of Weight Concerns had the shortest survival time (12% incidence by age 14.5) and those scoring in the lowest quartile had the highest survival time (2% incidence by age 14.5; p <001). This finding is consistent with both theoretical and clinical perspectives and represents one of the first prospective demonstrations of a linkage between weight and body shape concerns and later onset of eating disorder symptoms. An understanding of the independent variables that predispose girls to development of symptoms is a useful step towards the establishment of a rational basis for the choice of a prevention intervention target. © 1994 by John Wiley & Sons, Inc.     

Are overweight children unhappy?: Body mass index, depressive symptoms, and overweight concerns in elementary school children

BACKGROUND: It is commonly believed that overweight children are unhappy with their weight. However, population-based data addressing this association are lacking. OBJECTIVES: To evaluate the association between obesity and depressive symptoms in a diverse, school-based sample of preadolescent children, and to examine whether overweight concerns play a role in this association. DESIGN, SETTING, AND PARTICIPANTS: Third-grade students (N = 868, mean age, 8.4 years) attending 13 public elementary schools in Northern California were measured for weight and height, and were asked to complete self-report assessments of depressive symptoms and overweight concerns. RESULTS: A modest association between depressive symptoms and body mass index (BMI; calculated as weight in kilograms divided by the square of height in meters) was found for girls (r = 0.14, P<.01), but not for boys (r = 0.01, P<.78). Among girls, depressive symptoms were strongly associated with overweight concerns (r = 0.32, P<.001). After controlling for level of overweight concerns, BMI was no longer significantly associated with depressive symptoms among girls. In contrast, after controlling for BMI, overweight concerns remained significantly associated with depressive symptoms. CONCLUSIONS: This study provides cross-sectional evidence for a relationship between depressive symptoms and BMI in preadolescent girls, but not in preadolescent boys. This relationship seems to be explained by an excess of overweight concerns. Assessing overweight concerns may be a useful method to identify those overweight girls who are at highest risk for associated depressive symptoms.     

Associations among familism, language preference, and education in Mexican-American mothers and their children

Latino families who express a higher degree of familism are characterized by positive interpersonal familial relationships, high family unity, social support, interdependence in the completion of daily activities, and close proximity with extended family members. Retention of cultural values, such as familism, may be linked to positive health outcomes; however, little is known about how families retain culture of origin values in the face of acculturation pressures. The current study explores acculturation influences as indexed by language preference and household education on maternal and child familism. Mothers and children of Mexican descent (fourth grade students) (n = 219) completed measures of demographics, household education, language preference, and familism. Three hypotheses were examined. First, we predicted that lower household education would be correlated with higher familism scores. However, contrary to our prediction, a higher familism score was significantly associated with a higher level of household education (p <.05). Second, we predicted that higher child familism would be associated with the preference for speaking Spanish. Children who preferred to use both English and Spanish (p <.01) or English alone (p <.05) had higher familism scores than those who preferred Spanish. Third, we predicted that lower child familism scores would be associated with greater differences in mother and child language preferences. There were no significant differences in child familism based on differences between parent and child language. Protective influences of cultural maintenance deserve further attention in longitudinal studies and in relation to the physical and mental health of youth.     

Are perceived neighborhood hazards a barrier to physical activity in children?

BACKGROUND: We hypothesized that children's perceptions of more neighborhood hazards would be associated with less physical activity, less aerobic fitness, and a higher body mass index. OBJECTIVE: To examine the association between a hazardous neighborhood context and physical activity in children. METHODS: Fourth-grade students (n = 796) of diverse ethnic and economic backgrounds completed measures of neighborhood hazards, self-reported physical activity, physical fitness, height, and weight. Parents (n = 518) completed telephone interviews and provided data on their education level and occupation. RESULTS: As expected, children from families of lower socioeconomic status perceived significantly more neighborhood hazards. Contrary to our hypothesis, the perception of more hazards was significantly associated with more reported physical activity. This finding was not explained by school heterogeneity, alteration of the hazards measure, or differences in socioeconomic status. CONCLUSION: To further examine the relationship between neighborhood hazards and physical activity, we suggest that future studies include assessments of sedentary behavior, parental fear of violence, parental regulation of children's leisure activities, and cost and quality of available play areas and organized sports.     

Emergency Medicine Interest Groups

Emergency Medicine Interest Groups (EMIGs) serve as a bountiful resource for students interested in pursuing a career in Emergency Medicine (EM). In this article we elaborate on how medical students can get involved as members in an EMIG, discuss opportunities for leadership through these groups, detail how to make the most out of the EMIG (including a listing of important lectures, workshops/labs and opportunities for growth and advancement), provide a framework for how to institute a new EMIG when one does not exist, and discuss considerations for international EMIG groups.
