Reading related white matter structures in adolescents are influenced more by dysregulation of emotion than behavior.

Mood disorders and behavioral are broad psychiatric diagnostic categories that have different symptoms and neurobiological mechanisms, but share some neurocognitive similarities, one of which is an elevated risk for reading deficit. Our aim was to determine the influence of mood versus behavioral dysregulation on reading ability and neural correlates supporting these skills in youth, using diffusion tensor imaging in 11- to 17-year-old children and youths with mood disorders or behavioral disorders and age-matched healthy controls. The three groups differed only in phonological processing and passage comprehension. Youth with mood disorders scored higher on the phonological test but had lower comprehension scores than children with behavioral disorders and controls; control participants scored the highest. Correlations between fractional anisotropy and phonological processing in the left Arcuate Fasciculus showed a significant difference between groups and were strongest in behavioral disorders, intermediate in mood disorders, and lowest in controls. Correlations between these measures in the left Inferior Longitudinal Fasciculus were significantly greater than in controls for mood but not for behavioral disorders. Youth with mood disorders share a deficit in the executive-limbic pathway (Arcuate Fasciculus) with behavioral-disordered youth, suggesting reduced capacity for engaging frontal regions for phonological processing or passage comprehension tasks and increased reliance on the ventral tract (e.g., the Inferior Longitudinal Fasciculus). The low passage comprehension scores in mood disorder may result from engaging the left hemisphere. Neural pathways for reading differ mainly in executive-limbic circuitry. This new insight may aid clinicians in providing appropriate intervention for each disorder.

Effects of Adenotonsillectomy on Parent-Reported Behavior in Children With Obstructive Sleep Apnea.

Objectives: The childhood obstructive sleep apnea syndrome (OSAS) is associated with behavioral abnormalities. Studies on the effects of OSAS treatment on behavior are conflicting, with few studies using a randomized design. Further, studies may be confounded by the inclusion of behavioral outcome measures directly related to sleep. The objective of this study was to determine the effect of adenotonsillectomy on behavior in children with OSAS. We hypothesized that surgery would improve behavioral ratings, even when sleep symptom items were excluded from the analysis. Methods: This was a secondary analysis of Child Behavior Checklist (CBCL) data, with and without exclusion of sleep-specific items, from the Childhood Adenotonsillectomy Trial (CHAT). CBCL was completed by caregivers of 380 children (7.0+1.4 [range 5-9] years) with OSAS randomized to early adenotonsillectomy (eAT) versus 7 months of watchful waiting with supportive care (WWSC). Results: There was a high prevalence of behavioral problems at baseline; 16.6% of children had a Total Problems score in the clinically abnormal range. At follow-up, there were significant improvements in Total Problems (p < .001), Internalizing Behaviors (p = .04), Somatic Complaints (p = .01), and Thought Problems (p = .01) in eAT vs. WWSC participants. When specific sleep-related question items were removed from the analysis, eAT showed an overall improvement in Total (p = .02) and Other (p = .01) problems. Black children had less improvement in behavior following eAT than white children, but this difference attenuated when sleep-related items were excluded. Conclusions: This large, randomized trial showed that adenotonsillectomy for OSAS improved parent-rated behavioral problems, even when sleep-specific behavioral issues were excluded from the analysis.

Practice and documentation of performance of colonoscopy in a central Canadian health region.

OBJECTIVE: To evaluate the reporting and performance of colonoscopy in a large urban centre. METHODS: Colonoscopies performed between January and April 2008 in community hospitals and academic centres in the Winnipeg Regional Health Authority (Manitoba) were identified from hospital discharge databases and retrospective review of a random sample of identified charts. Information regarding reporting of colonoscopies (including bowel preparation, photodocumentation of cecum/ileum, size, site, characteristics and method of polyp removal), colonoscopy completion rates and follow-up recommendations was extracted. Colonoscopy completion rates were compared among different groups of physicians. RESULTS: A total of 797 colonoscopies were evaluated. Several deficiencies in reporting were identified. For example, bowel preparation quality was reported in only 20%, the agent used for bowel preparation was recorded in 50%, photodocumentation of colonoscopy completion in 6% and polyp appearance (ie, pedunculated or not) in 34%, and polyp size in 66%. Although the overall colonoscopy completion rate was 92%, there was a significant difference among physicians with varying medical specialty training and volume of procedures performed. Recommendations for follow-up procedures (barium enema, computed tomography colonography or repeat colonoscopy) were recorded for a minority of individuals with reported poor bowel preparation or incomplete colonoscopy. CONCLUSIONS: The present study found many deficiencies in reporting of colonoscopy in typical, city-wide clinical practices. Colonoscopy completion rates varied among different physician specialties. There is an urgent need to adopt standardized colonoscopy reporting systems in everyday practice and to provide feedback to physicians regarding deficiencies so they can be rectified.

Colonoscopy and its complications across a Canadian regional health authority.

BACKGROUND: Defining the complication rate of endoscopy performed across an entire city will capture usual as opposed to referral center data. OBJECTIVE: Our purpose was to evaluate the current practice of colonoscopy and complications associated with lower GI endoscopy in usual clinical practice. DESIGN: All admissions within 30 days of an outpatient lower GI endoscopy at any of the 6 adult-care Winnipeg hospitals were identified. This includes endoscopy for both complex and routine patients. A chart audit of all cases with potential complications was performed. RESULTS: A total of 24,509 outpatient lower GI endoscopies for adults were performed at the 6 hospitals over the 2 study years (April 1, 2004, to March 31, 2006). There were 303 admissions with potential complications. The colonoscopy completion rate was 65% (72% for gastroenterologists vs 59% for general surgeons, P < .005). Quality of bowel preparation and nature of polyps were often not documented. The overall rate of complications was 2.9/1000 procedures; the perforation rate after polypectomy was 1.8/1000; and the postpolypectomy bleeding rate was 6.4/1000. Most (67%) complications were recognized after discharge for the index procedure. The complication rate was highest for the endoscopists performing fewer than 200 procedures per year (5.4/1000 vs 2.7/1000 for the rest, P = .02, relative risk 2 [95% CI, 1.1-3.7]). LIMITATIONS: Chart audit was limited to cases requiring admission within 30 days of the index procedure. CONCLUSIONS: The overall complication rate after lower GI endoscopy in usual clinical practice in Winnipeg is comparable to that previously reported. A higher complication rate after endoscopy by low-volume endoscopists needs to be further evaluated. The reporting of endoscopy must be standardized to enhance outcomes interpretation.

Improved neurodevelopmental outcomes for extremely low birth weight infants in 2000-2002.

BACKGROUND: Neurodevelopmental impairment of extremely low birth weight infants increased in the 1990s. Modern therapeutic changes may have influenced more recent neonatal outcomes. OBJECTIVE: We sought to compare neonatal therapies and outcomes among all extremely low birth weight infants born in 2000-2002 (period III) to 2 previous periods: 1982-1989 (period I) and 1990-1999 (period II). METHODS: The population included 496 extremely low birth weight infants born at our perinatal center during period I, 749 during period II, and 233 during period III. Therapies, rates of death, and survival with and without impairment at 20 months' corrected age were compared. RESULTS: Between periods I and II, survival increased from 49% to 68% as did neonatal morbidity. This resulted in increased survival without impairment but also increased survival with impairment. Changes in therapy during period III included an increase in antenatal steroid use and a decrease in postnatal steroid use, although the rate of chronic lung disease did not change. Sepsis decreased, as did severe intraventricular hemorrhage. On follow-up, the rate of cerebral palsy decreased from 13% to 5%, resulting in a decrease in neurodevelopmental impairment from 35% to 23%. As a result, during period III versus II, survival without impairment increased, whereas survival with impairment decreased. CONCLUSION: Since 2000, neurodevelopmental impairment has decreased among extremely low birth weight infants. A variety of perinatal and neonatal factors were associated with the improved outcomes including increased antenatal steroid use and cesarean section delivery, as well as decreased sepsis, severe cranial ultrasound abnormalities, and postnatal steroid use despite no change in the rate of chronic lung disease.

The impact of extremely low birth weight on the families of school-aged children.

OBJECTIVE: The purpose of this study was to document the impact and burden of extremely low birth weight (<1000 g) and associated problems on the families of school-aged children in a controlled study. The study was also designed to document the salient predictors of individual differences of family impact within the extremely low birth weight group. METHODS: A prospective study was completed at 8 years of a cohort of 219 children with extremely low birth weight born 1992-1995 and 176 children with normal birth weight. Measures included the following predictor variables: socioeconomic status and parent risk, birth risk, neonatal risk, neurodevelopmental outcome, impairment in adaptive abilities, and functional impact of chronic conditions. The primary outcome measure was the Impact on Family scale. A measure of family stressors and resources (the Life Stressors and Social Resources Inventory) was also obtained. RESULTS: The primary finding was that the total family impact was greater in the extremely low birth weight group compared with controls. Moreover, the negative impact on family in specific domains was greater in the extremely low birth weight group in financial impact, caretaker burden, and familial burden. These differences were not attributable to general family stressors, socioeconomic status, child, gender, or race. Higher parent/socioeconomic risk, neurodevelopmental outcomes, and the functional impact of chronic conditions predicted greater family impact within the extremely low birth weight group, whereas birth and neonatal risk scores did not. CONCLUSIONS: Extremely low birth weight was associated with a negative impact on families. Socioeconomic parental risk, but most especially child-related factors such as neurodevelopmental and the functional impact of chronic conditions, predicted the negative family impact within the extremely low birth weight group. Findings underscore the need to develop and test interventions to provide support for families of extremely low birth weight infants to ameliorate the burden of extremely low birth weight and associated risk factors on families.

Predictors of internalizing symptoms among very low birth weight young women.

As part of a longitudinal study of the outcomes of very low birth weight children (<1.5 kg), we sought to examine the perinatal, childhood, and young adult predictors of internalizing symptoms among very low birth weight young women and their normal birth weight controls. The cohort included 125 very low birth weight and 124 normal birth weight 20-year-old subjects. Perinatal, childhood, and young adult predictors were examined via stepwise multivariate analyses. Results revealed very low birth weight to be a significant predictor of parent-reported internalizing symptoms of their daughters but only among white subjects who had mothers with high levels of psychological distress. Additional significant predictors of 20-year internalizing symptoms included child I.Q. and internalizing symptoms at age 8 years and family expressiveness. When the results were analyzed according to the young adult self-report, additional predictors of internalizing symptoms included a history of asthma and exposure to violence. Perinatal risk factors were not found to be predictive of internalizing symptoms at age 20 years. Future studies should prospectively examine social and environmental factors associated with the neonatal intensive care experience that might explain the effect of very low birth weight on later psychopathology.

The effect of maternal milk on neonatal morbidity of very low-birth-weight infants.

OBJECTIVE: To examine the dose effect of maternal milk on neonatal morbidity of very low-birth-weight (<1.5 kg) infants. DESIGN: Prospective observational study. SETTING: An urban tertiary care neonatal intensive care unit and follow-up clinic. POPULATION: One hundred nineteen singleton very low-birth-weight infants admitted from January 1, 1997, to February 14, 1999 (mean birth weight, 1056 g; mean gestational age, 28 weeks; 57% male; and 43% white). METHODS: A comparison of the effect on neonatal outcomes of daily graded doses (1-24, 25-49, and > or = 50 mL/kg of body weight) of maternal milk through week 4 of life vs a reference group receiving no maternal milk. MAIN OUTCOME MEASURES: Neonatal outcomes examined included rates of sepsis after age 5 days, retinopathy of prematurity, chronic lung disease, necrotizing enterocolitis, jaundice, duration of ventilator dependence, and length of hospital stay. RESULTS: Seventy-nine infants (66%) received maternal milk, of whom 32 received at least 50 mL/kg per day through week 4 of life. Poisson regression analysis adjusting for birth weight, sex, and ethnicity revealed that the mean number of episodes of sepsis for infants receiving at least 50 mL/kg per day was lower by a factor of 0.27 (95% confidence interval, 0.08-0.95) compared with infants receiving no maternal milk. There was no effect of maternal milk on other neonatal outcomes. CONCLUSIONS: A daily threshold amount of at least 50 mL/kg of maternal milk through week 4 of life is needed to decrease the rate of sepsis in very low-birth-weight infants, but maternal milk does not affect other neonatal morbidities.
