Cumulative incidence of secondary neoplasms as a first event after childhood acute lymphoblastic leukemia

Context  Little is known about the incidence of secondary neoplasms after 15 to 20 years in children and adolescents who were treated for acute lymphoblastic leukemia. Objectives  To investigate the cumulative incidence of secondary neoplasms in pediatric patients treated for acute lymphoblastic leukemia over 30 years and to characterize late-occurring tumors. Design, Setting, and Patients  Retrospective study of 2169 patients with acute lymphoblastic leukemia treated between 1962 and 1998 at St Jude Children's Research Hospital, Memphis, Tenn, who achieved complete remission and had a median follow-up time of 18.7 years (range, 2.4-41.3 years). Main Outcome Measures  Cumulative incidences of secondary neoplasms in first remission and standard incidence ratios of observed rates compared with rates of cancer development in the general US population. Results  Secondary neoplasms developed as the first event in 123 patients and comprised 46 myeloid malignancies, 3 lymphomas, 14 basal cell carcinomas, 16 other carcinomas, 6 sarcomas, 16 meningiomas, and 22 other brain tumors. The cumulative incidence of secondary neoplasm was 4.17% (SE, 0.46%) at 15 years and increased substantially after 20 years, reaching 10.85% (SE, 1.27%) at 30 years. When meningiomas and basal cell carcinomas were excluded, the overall cumulative incidence was 3.99% (SE, 0.44%) at 15 years and 6.27% (SE, 0.83%) at 30 years, representing a 13.5-fold increase in overall risk compared with the general population. The cumulative incidence of each tumor type at 30 years was 2.19% (SE, 0.32%) for myeloid malignancy, 0.17% (SE, 0.10%) for lymphoma, 3.00% (SE, 0.59%) for brain tumor, 4.91% (SE, 1.04%) for carcinoma, and 0.57% (SE, 0.37%) for sarcoma. Conclusions  The cumulative incidence of secondary neoplasms increases steadily over 30 years after treatment of acute lymphoblastic leukemia. Although the majority of the late-occurring secondary neoplasms are low-grade tumors, the increase in incidence of more aggressive malignant neoplasms is significantly higher than expected in the general population. These results suggest that lifelong follow-up of acute lymphoblastic leukemia survivors is needed to ascertain the full impact of treatment and other leukemia-related factors on secondary neoplasm development.      

Vital Signs: Changes in Firearm Homicide and Suicide Rates — United States, 2019–2020

IntroductionThe majority of homicides (79%) and suicides (53%) in the United States involved a firearm in 2020. High firearm homicide and suicide rates and corresponding inequities by race and ethnicity and poverty level represent important public health concerns. This study examined changes in firearm homicide and firearm suicide rates coinciding with the emergence of the COVID-19 pandemic in 2020.MethodsNational vital statistics and population data were integrated with urbanization and poverty measures at the county level. Population-based firearm homicide and suicide rates were examined by age, sex, race and ethnicity, geographic area, level of urbanization, and level of poverty.ResultsFrom 2019 to 2020, the overall firearm homicide rate increased 34.6%, from 4.6 to 6.1 per 100,000 persons. The largest increases occurred among non-Hispanic Black or African American males aged 10–44 years and non-Hispanic American Indian or Alaska Native (AI/AN) males aged 25–44 years. Rates of firearm homicide were lowest and increased least at the lowest poverty level and were higher and showed larger increases at higher poverty levels. The overall firearm suicide rate remained relatively unchanged from 2019 to 2020 (7.9 to 8.1); however, in some populations, including AI/AN males aged 10–44 years, rates did increase.Conclusions and Implications for Public Health PracticeDuring the COVID-19 pandemic, the firearm homicide rate in the United States reached its highest level since 1994, with substantial increases among several population subgroups. These increases have widened disparities in rates by race and ethnicity and poverty level. Several increases in firearm suicide rates were also observed. Implementation of comprehensive strategies employing proven approaches that address underlying economic, physical, and social conditions contributing to the risks for violence and suicide is urgently needed to reduce these rates and disparities.     

The Relation of Caregiver Demand to Adjustment Outcomes in Children With Cancer: The Moderating Role of Parenting Stress

This study investigated the relation of caregiver demand (CD) and parenting stress (PS) to child adjustment in a pediatric cancer sample. Mothers of children with cancer completed measures of PS and CD and rated their child's emotional, behavioral, and social adjustment. PS emerged as an independent predictor of the child's emotional, behavioral, and social adjustment; and moderated the relation between CD and child internalizing problems (IP). Contrary to expectations, children evidenced fewer IP under conditions of high CD and low PS, and more IP under conditions of low CD and low PS.     

Substance Use and Sexual Risk Behavior in HIV-Positive Men Who Have Sex With Men: An Episode-Level Analysis

Men who have sex with men (MSM) make up nearly half of all people living with HIV in the United States. The prevalence of the epidemic in this population makes it vitally important to understand the transmission of the infection and to develop methods to prevent its spread. The current study uses longitudinal diary methods to examine relationships between substance use and unprotected anal intercourse in a sample of 158 HIV-positive, mostly ethnic minority MSM. Results indicate that both general substance use and use of specific drugs (i.e., inhalants, cocaine, crack, and club drugs) have a substantial impact on the sexual risk behavior of this population.     

Incremental Development of an Integrated Assessment Method for the Professional Curriculum

Objective. To incrementally create and embed biannual integrated knowledge and skills examinations into final examinations of the pharmacy practice courses offered in the first 3 years of the pharmacy curriculum that would account for 10% of each course’s final course grade.Design. An ad hoc integrated examination committee was formed and tasked with addressing 4 key questions. Integrated examination committees for the first, second, and third years of the curriculum were established and tasked with identifying the most pertinent skills and knowledge-based content from each required course in the curriculum, developing measurable objectives addressing the pertinent content, and creating or revising multiple-choice and performance-based questions derived from integrated examination objectives. An Integrated Examination Review Committee evaluated all test questions, objectives, and student performance on each question, and revised the objectives and questions as needed for the following year’s iteration. Eight performance objectives for the examinations were measured.Assessment. All 8 performance objectives were achieved. Sixty-four percent of the college’s faculty members participated in the integrated examination process, improving the quality of the examination. The incremental development and implementation of the examinations over a 3-year period minimized the burden on faculty time while engaging them in the process. Student understanding of expectations for knowledge and skill retention in the curriculum also improved.Conclusions. Development of biannual integrated examinations in the first 3 years of the classroom curriculum enhanced the college’s culture of assessment and addressed accreditation guidelines for formative and summative assessment of students’ knowledge and skills. The course will continue to be refined each year.
