Building upon the literature in developmental and life-course criminology, the present study assesses the possible association of age onset of delinquency with the trajectory of alcohol-impaired driving using data collected from the three waves of the Buffalo Longitudinal Survey of Young Men (BLSYM). It is argued that as a unique form of delinquency, alcohol-impaired driving among adolescents may be better understood in a broad context of adolescent delinquency involvement. The study adopts the general approach for the analysis of early onset of delinquency and criminal careers in developmental and life-course criminology and hypothesizes that early onset of delinquency is associated with a higher growth of alcohol-impaired driving over time among adolescents when age onsets of alcohol-impaired driving, drinking, and drug use are controlled. Our analysis with the HLM growth modeling method provides support for the hypothesis. Respondents who had an early start in delinquency were likely to have a faster growth of alcohol-impaired driving over the three waves of BLSYM, which implies that these respondents were likely to have a longer path of alcohol-impaired driving in their transition to adulthood. The implication of this finding is discussed.

PURPOSE

This study compared visuomotor speed and cognitive flexibility in emphysema patients treated either with standard multidisciplinary medical therapy (MT) or lung volume reduction surgery (LVRS), followed over a 2-year period.

METHODS

MT patients (n=544) and 542 LVRS patients completed the Trail Making Test (TMT) Parts A and B prior to randomization (baseline). Testing was repeated at 1 and 2 years.

RESULTS

There were no differences on scores for TMT Part A and B between the LVRS and MT groups at baseline or at years 1 and 2. No significant difference between MT and LVRS was noted in terms of overall change in TMT Part A and B over 2 years. The MT group had a significant improvement on TMT-Part A at each followup time compared to baseline (P<.03) but the LVRS group did not. Both the MT and LVRS groups had a significant decline in performance (increase in time to completion) on TMT-Part B when comparing year 1 to baseline (P<.0001).

CONCLUSION

Emphysema patients who received LVRS or MT as treatment performed similarly on measures of visuomotor speed and flexibility at baseline and 1 and 2 year followup. Both groups showed improvement on visuomotor speed during the first year yet overall cognitive flexibility declined. By the second year neither group had any significant change from baseline. These findings suggest that improvement on visuomotor speed and flexibility, observed in a previous 6-month study of LVRS subjects, was not sustained at 1 and 2 year followup.

Rationale: The characterization of young adults who develop late-onset diseases may augment the detection of novel genes and promote new pathogenic insights.

Methods: We analyzed data from 2,500 individuals of African and European ancestry in the COPDGene Study. Subjects with severe, early-onset chronic obstructive pulmonary disease (COPD) (n = 70, age < 55 yr, FEV1 < 50% predicted) were compared with older subjects with COPD (n = 306, age > 64 yr, FEV1 < 50% predicted).

Measurements and Main Results: Subjects with severe, early-onset COPD were predominantly females (66%), P = 0.0004. Proportionally, early-onset COPD was seen in 42% (25 of 59) of African Americans versus 14% (45 of 317) of non-Hispanic whites, P < 0.0001. Other risk factors included current smoking (56 vs. 17%, P < 0.0001) and self-report of asthma (39 vs. 25%, P = 0.008). Maternal smoking (70 vs. 44%, P = 0.0001) and maternal COPD (23 vs. 12%, P = 0.03) were reported more commonly in subjects with early-onset COPD. Multivariable regression analysis found association with African American race, odds ratio (OR), 7.5 (95% confidence interval [CI], 2.3–24; P = 0.0007); maternal COPD, OR, 4.7 (95% CI, 1.3–17; P = 0.02); female sex, OR, 3.1 (95% CI, 1.1–8.7; P = 0.03); and each pack-year of smoking, OR, 0.98 (95% CI, 0.96–1.0; P = 0.03).

Conclusions: These observations support the hypothesis that severe, early-onset COPD is prevalent in females and is influenced by maternal factors. Future genetic studies should evaluate (1) gene-by-sex interactions to address sex-specific genetic contributions and (2) gene-by-race interactions.

Purpose

Approximately 14-54% of patients with systemic lupus erythematosus without a history of major neuropsychiatric syndromes (nonNPSLE) have cognitive deficits. Elevated N-methyl-D-aspartate (NMDA) receptor antibodies (anti-NR2) have been reported in 35% of patients with SLE, but few studies have utilized controls or a composite memory index. We hypothesized that serum anti-NR2 would be elevated in nonNPSLE compared to healthy controls, and that elevated anti-NR2 would be associated with memory dysfunction and depression.

Methods

Subjects included 43 nonNPSLE patients with a mean age of 36.5 (SD=9.0) and mean education level of 14.7 years (SD=2.5). Twenty-seven healthy control subjects with similar demographic characteristics were also enrolled in this study. A global cognitive impairment index (CII) and a memory impairment index (MII) were calculated using impaired test scores from the ACR-SLE neuropsychological battery. Serum samples were analyzed using a standard ELISA for anti-NR2.

Results

Elevations of serum anti-NR2 were found in 14.0% of the nonNPSLE and 7.4% of the controls (p=0.47). There was no relationship between elevated anti-NR2 status and higher CII or performance on the MII. No relationship between levels of depressive symptoms and anti-NR2 was found.

Conclusions

The frequency of elevated anti-NR2 was low (14.0%) in this sample of SLE patients and not significantly different from controls. A relationship was not found between the presence of anti-NR2 in serum and global cognitive or memory indices, or with depression. Results suggest that serum anti-NR2 is not likely related to mild cognitive dysfunction in SLE patients without a prior history of NPSLE.

The present study assessed how the trajectory of delinquency affects the growth curve of alcohol-impaired driving using three-waves of data collected from the Buffalo Longitudinal Survey of Young Men (BLSYM). Using the structural equation modeling method, latent growth modeling was utilized to assess four age cohorts of sixteen, seventeen, eighteen, and nineteen years of age at the first wave. The data indicated that the growth rate of delinquency significantly and positively affects the growth rate of alcohol-impaired driving for the respondents who were sixteen at the first wave. The growth rate of drinking was also significantly and positively associated with the growth rate of alcohol-impaired driving for this age cohort. Although the growth rate of delinquency had no significant effect on the growth rate of alcohol-impaired driving for the age cohort which was seventeen at Wave 1, the growth rates of both drinking and drug use did affect for this age cohort. The data, however, showed that alcohol-impaired driving had a significant increase across the waves for the eighteen year old cohort, but there was no significant variation in the rate across respondents. Finally, for the nineteen year old cohort there was no significant increase in alcohol-impaired driving across the waves, and also no significant variation of the growth rate of alcohol-impaired driving across the respondents. These findings indicated that interventions focused on reducing delinquency, alcohol and drug use by sixteen and seventeen year old male adolescents will also reduce their alcohol-impaired driving.

Various psychological and cognitive difficulties have been documented in patients with emphysema. The aim of this article is to review prior literature on the prevalence of these difficulties in emphysema, as well as identify specific studies demonstrating improvement in these areas after therapy. Traditional therapies such as continuous and intermittent oxygen therapy and comprehensive pulmonary rehabilitation are reviewed. In general, these studies demonstrate reductions in symptoms of depression and anxiety as well as specific improvements in complex attention and verbal fluency. In a more recent study, patients with emphysema who underwent lung volume reduction surgery (LVRS) demonstrated improved psychomotor speed, verbal memory, and naming skills at 6 months compared with patients with emphysema who were in comprehensive rehabilitation only. The patients with emphysema who had LVRS also demonstrated greater decline in depressive symptoms compared with the rehabilitation patients at 6 months. There were no associations between improved neuropsychological tests and changes in depression, exercise tests, pulmonary function, oxygenation, or quality of life scores, and thus the mechanism of behavioral improvement identified in the patients who underwent LVRS remained unclear. Overall, studies suggest that psychological and cognitive improvements occur subsequent to a variety of medical and behavioral treatment therapeutic approaches, and that LVRS appears to have an advantage for some patients with emphysema.

Thirteen patients with systemic lupus erythematosus and depression (Depressed-SLE), 10 Depressed-Control subjects, and 25 Healthy Control subjects completed cognitive testing and self-report questionnaires of pain, depression, and fatigue. The Depressed-SLE group scored higher on the American College of Rheumatology Neuropsychological Battery for systemic lupus erythematosus cognitive impairment index compared to Depressed-Control and Healthy Control subjects (p < 0.05 and p < 0.02, respectively). No correlations between cognitive impairment and pain, fatigue, or perceived cognitive failures were observed in the Depressed-SLE participants. Moderate agreement (86.4%) was found between a comprehensive neuropsychology battery cognitive impairment index and the ACR-SLE impairment index in the Depressed-SLE patients. Overall, the magnitude and pattern of cognitive impairment in Depressed-SLE patients cannot be explained by depression alone.
