Magnetic field exposure and long-term survival among children with leukaemia
We examined the association between magnetic field (MF) exposure and survival among children with acute lymphoblastic leukaemia (ALL) treated at 51 Pediatric Oncology Group centres between 1996 and 2001. Of 1672 potentially eligible children under treatment, 482 (29%) participated and personal 24-h MF measurements were obtained from 412 participants. A total of 386 children with ALL and 361 with B-precursor ALL were included in the analysis of event-free survival (time from diagnosis to first treatment failure, relapse, secondary malignancy, or death) and overall survival. After adjustment for risk group and socioeconomic status, the event-free survival hazard ratio (HR) for children with measurements ⩾0.3 μT was 1.9 (95% confidence interval (CI) 0.8, 4.9), compared to <0.1 μT. For survival, elevated HRs were found for children exposed to ⩾0.3 μT (multivariate HR=4.5, 95% CI 1.5–13.8) but based on only four deaths among 19 children. While risk was increased among children with exposures above 0.3 μT, the small numbers limited inferences for this finding
Can Systemic Interventions Designed to Reduce Reoffending by Youth also Reduce their Victimization?
Previous research indicates considerable overlap between populations of boys who are victimized and boys who victimize others. This study was concerned with whether a systems-focused treatment program designed to address individual and systemic risk factors associated with the perpetration of sexual and violent crimes might also be successful in reducing boys’ victimization by others. Boys adjudicated for sexual offences who received ‘treatment as usual’ (TAU; n = 335) were compared with similarly adjudicated boys who completed the treatment program (n = 200) on their histories of contact with police either as offenders or victims. Despite their higher rates of pre-intervention victimization, the treatment group were victimized less frequently post-intervention than the TAU group. Continued offending was the strongest predictor of victimization post-intervention. These findings suggest that offending and victimization share common risk factors that may be addressed simultaneously within offence-focused treatment
Patient-Perceived Changes in the System of Values After Cancer Diagnosis
A cross-sectional study investigated changes in patients’ value systems following a diagnosis of cancer. Fifty patients at 1 to 6 months following cancer diagnosis, were asked to compare their current values with their recollection of past values. Using the Rokeach Value Survey we obtained statistically significant results showing that twenty-seven out of thirty-six values changed their importance from the patients’ perspective: 16 values significantly increased, while 11 values significantly decreased in importance. Changes with respect to nine values were insignificant. We indentified clusters of values increasing in importance the most: Religious morality (Salvation, Forgiving, Helpful, Clean), Personal orientation (Self-Respect, True Friendship, Happiness), Self-constriction (Self-Controlled, Obedient, Honest), Family security (Family Security, Responsible), and Delayed gratification (Wisdom, Inner Harmony). We also observed that the following value clusters decreased in importance: Immediate gratification (An Exciting Life, Pleasure, A Comfortable Life); Self-expansion (Capable, Ambitious, Broadminded), Competence (A Sense of Accomplishment, Imaginative, Intellectual). The remaining values belonged to clusters that as a group changed slightly or not at all. Practical implications of the study are discussed
Ceratocystis manginecans associated with a serious wilt disease of two native legume trees in Oman and Pakistan
A serious wilt disease has recently been found
on Prosopis cineraria (Ghaf) in Oman and on
Dalbergia sissoo (Shisham) in Pakistan. Disease symptoms
on both these native, leguminous hosts include
vascular discolouration and partial or complete wilt of
affected trees. A species of Ceratocystis was consistently
isolated from symptomatic material. Morphological
comparisons and analyses of DNA sequence data of
the ITS, β-tubulin, and EF 1-α gene regions showed
that the Ceratocystis isolates obtained from both tree
species represent C. manginecans. This is the same
pathogen that is causing the devastating mango sudden
decline disease in Oman and Pakistan. This is also the
same pathogen that has been reported causing a wilting
disease on Acacia mangium in Indonesia. Cross inoculation
with C. manginecans isolates from P. cineraria,
D. sissoo and mango showed that the fungus can cause
disease on all three trees.Tree Protection Cooperative Programme (TPCP), University of Pretoria, South Africa,
