Declines Noted in Cognitive Processes and Association With Achievement Among Children With Leukemia.

PURPOSE/OBJECTIVES: To assess change in specific cognitive processes during treatment with chemotherapy only among children with acute lymphoblastic leukemia (ALL). 
. DESIGN: A prospective, repeated measures design.
. SETTING: Pediatric oncology treatment centers at Banner-University Medical Center Tucson/Banner Children's-Diamond Medical Center (University of Arizona) and Texas Children's Cancer and Hematology centers (Baylor College of Medicine) in Houston. 
. SAMPLE: 71 children with ALL, with a mean age of 6.18 years at the time of diagnosis. 
. METHODS: Using mixed-effects latent growth curve modeling with time since diagnosis as a fixed effect, age-adjusted standardized measures of working memory, processing speed, executive function, and attention were obtained and repeated about one and two years later. A subsample was tested for academic achievement at the end of treatment.
. MAIN RESEARCH VARIABLES: Verbal working memory, visual spatial memory, processing speed, academic achievement, age, and gender. 
. FINDINGS: A significant main effect was observed for age at diagnosis on decline in verbal working memory during treatment. Planned contrasts revealed greater decline among children who were diagnosed when aged younger than five years compared to those diagnosed when aged five years or older. Decline in verbal working memory and achievement in letter-word identification and calculation skills were associated, and decline in spatial memory was associated with calculation. A main effect of gender was observed on processing speed, with female patients showing greater decline than male patients. 
. CONCLUSIONS: Findings from this study may guide the timing of interventions that could improve school achievement among survivors. 
. IMPLICATIONS FOR NURSING: Children undergoing treatment for ALL may experience issues with verbal working memory and increased difficulty in school. Nurses are in a position to refer parents and children to school resources for additional academic support.

Retained Products of Conception: An Atypical Presentation Diagnosed Immediately with Bedside Emergency Ultrasound.

Background. Retained products of conception is an important diagnosis to consider in patients presenting with postpartum complaints. Bedside ultrasound is a rapid, accurate, noninvasive modality to evaluate these patients. Objective. To report an atypical case of retained products of conception diagnosed with bedside ultrasound in the emergency department. Case Report. A 27-year-old female who was 1-month postpartum presented with vaginal bleeding, pelvic pain, and no fever. At the time of initial H&P, bedside ultrasound revealed echogenic material within the endometrial cavity with blood flow seen by color Doppler consistent with retained products of conception. The bedside ultrasound rapidly narrowed the differential and allowed a definitive diagnosis immediately. Ob/Gyn was consulted and dilation and curettage was performed in the operating room. Conclusions. Retained products of conception is an important diagnosis for the emergency physician to consider in at-risk patients. The sonographic findings are easily obtained and interpreted by emergency physicians. Earlier diagnosis of this disease process should lead to more focused patient evaluations and management.

Neurocognitive Predictors of Academic Outcomes Among Childhood Leukemia Survivors.

BACKGROUND: Acute lymphoblastic leukemia is the most common pediatric cancer, and survival approaches 90%. Acute lymphoblastic leukemia survivors are more likely than healthy peers or siblings to experience academic underachievement, yet little is known about neurocognitive predictors of academic outcomes. OBJECTIVES: Objectives were to compare neurocognitive abilities to age-adjusted standardized norms, examine change over time in neurocognitive abilities, and establish neurocognitive predictors of academic outcomes. METHODS: Seventy-one children were followed over the course of therapy. Cognitive abilities were assessed during induction when the child was in remission (baseline) and annually for 3 years (years 1, 2, and 3). Reading and mathematics abilities were assessed at year 3. RESULTS: Fine motor dexterity was significantly below age-adjusted norms at all data points but showed improvement over time. Baseline visual-motor integration was within the reference range but significantly declined by year 3, and mean scores at years 2 and 3 were significantly below age-adjusted norms. Verbal short-term memory was significantly below age-adjusted norms at all assessments. Visual-motor integration predicted reading and mathematics abilities. Verbal short-term memory predicted reading abilities, and visual short-term memory predicted mathematics abilities. CONCLUSIONS: Central nervous system-directed therapy is associated with specific neurocognitive problems. Visual-spatial skills and verbal and visual short-term memory predict academic outcomes. IMPLICATIONS FOR PRACTICE: Early assessment of visual-spatial perception and short-term memory can identify children at risk of academic problems. Children who are at risk of academic problems could benefit from a school-based individual educational program and/or educational intervention.

Oxidative Stress, Motor Abilities, and Behavioral Adjustment in Children Treated for Acute Lymphoblastic Leukemia.

PURPOSE/OBJECTIVES: To examine associations among oxidative stress, fine and visual-motor abilities, and behavioral adjustment in children receiving chemotherapy for acute lymphoblastic leukemia (ALL)
. DESIGN: A prospective, repeated-measures design
. SETTING: Two pediatric oncology settings in the southwestern United States. SAMPLE: 89 children with ALL were followed from diagnosis to the end of chemotherapy. METHODS: Serial cerebrospinal fluid samples were collected during scheduled lumbar punctures and analyzed for oxidative stress biomarkers. Children completed fine motor dexterity, visual processing speed, and visual-motor integration measures at three time points. Parents completed child behavior ratings at the same times. MAIN RESEARCH VARIABLES: Oxidative stress, fine motor dexterity, visual processing, visual-motor integration, and behavioral adjustment
. FINDINGS: Children with ALL had below-average fine motor dexterity, visual processing speed, and visual-motor integration following the induction phase of ALL therapy. By end of therapy, visual processing speed normalized, and fine motor dexterity and visual-motor integration remained below average. Oxidative stress measures correlated with fine motor dexterity and visual-motor integration. Decreased motor functioning was associated with increased hyperactivity and anxiety
. CONCLUSIONS: Oxidative stress occurs following chemo-therapy for childhood ALL and is related to impaired fine motor skills and visual symptoms
. IMPLICATIONS FOR NURSING: Early intervention should be considered to prevent fine motor and visual-spatial deficits, as well as behavioral problems.

Correlation between ED symptoms and clinical outcomes in the patient with aneurysmal subarachnoid hemorrhage.

INTRODUCTION: Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating neurologic insult often presenting to the emergency department as a headache. Recognition and prompt treatment are important to good outcomes. The purpose of this analysis was to examine the presentation of aSAH patients to the emergency department and determine whether presentation predicts length of stay or death. METHODS: This is a retrospective review of data gathered from 2 existing studies. Data from patients diagnosed with acute aSAH were reviewed for symptoms, clinical presentation, history, demographics, and laboratory results. Statistical analysis was completed by use of χ(2) and regression analysis. RESULTS: This sample of 193 adult aSAH patients confirmed headache as well as meningeal signs as the most frequent symptom on presentation to the emergency department, and this was cited as the most common reason for seeking medical treatment. Symptom presentation did not appear to affect length of stay; however, survival analysis showed that patients who presented with a Hunt and Hess grade greater than 3 along with bradycardia were 15.6 times more likely to die within the first month of aSAH. DISCUSSION: Although aSAH presentation remains the same, this analysis did find a correlation between poor clinical grade and bradycardia to be a significant predictor of death at 30 days. Additional study may help to determine whether any intervention could lessen this effect. Although patient diagnosis and referral from the community emergency department to a tertiary center were relatively quick, there was a wide window of time between patient recognition of symptoms and seeking medical treatment.

Hemophilia Growth and Development Study: caregiver report of youth and family adjustment to HIV disease and immunologic compromise.

OBJECTIVE: To assess differences in caregiver report of youth and family psychosocial adjustment associated with HIV infection and greater immune compromise in youths with hemophilia. METHODS: Caregivers of 162 boys with hemophilia 8 to 20 years old completed three youth and family questionnaires (Personality Inventory for Children, Revised [PIC-R]; Questionnaire on Resources and Stress [QRS]; Family Environment Scale). RESULTS: Caregivers of HIV positive (HIV+) youths reported greater health concerns, social withdrawal (PIC-R), physical and adaptive limitations associated with illness (QRS) in their sons, and more pessimism about their sons' future and negative attitudes about parenting (QRS). Caregivers of HIV+ youths with greater immune compromise reported greater concerns about their sons' health and greater pessimism about their futures, as well as lower levels of family integration and more limited family opportunities. CONCLUSIONS: Results suggest caregivers perceive psychosocial problems in HIV+ youths with hemophilia and their families; some problems are specifically associated with greater immune compromise.
