Long-term outcomes of office-based buprenorphine/naloxone maintenance therapy.

BACKGROUND: Buprenorphine/naloxone was approved by the FDA for office-based opioid maintenance therapy (OMT), with little long-term follow-up data from actual office-based practice. 18-Month outcome data on the office-based use of buprenorphine/naloxone (bup/nx) and the impact of socioeconomic status and other patient characteristics on the duration and clinical effects of bup/nx are reported. METHODS: This retrospective chart review and cross-sectional telephone interview provide treatment retention of opioid-dependent patients receiving bup/nx-OMT in an office-based setting. 176 opioid-dependent patients from two different socioeconomic groups (high and low SES) were begun on bup/nx, started intensive outpatient treatment, and followed-up after a minimum of 18 months (18-42 months) by telephone interview to assess treatment outcome. RESULTS: 110 subjects (67%) completed the interview, 77% remained on bup/nx with no difference in retention between high and low SES groups. Those on bup/nx at follow-up were more likely to report abstinence, to be affiliated with 12-step recovery, to be employed and to have improved functional status. CONCLUSIONS: Bup/nx-OMT is a viable treatment option and when coupled with a required abstinence oriented addiction counseling program is effective in promoting abstinence, self-help group attendance, occupational stability, and improved psychosocial outcomes in both low SES and high SES patient populations over an 18-42-month period.

Delusional versus nondelusional body dysmorphic disorder: clinical features and course of illness.

DSM-IV's classification of body dysmorphic disorder (BDD) is controversial. Whereas BDD is classified as a somatoform disorder, its delusional variant is classified as a psychotic disorder. However, the relationship between these BDD variants has received little investigation. In this study, we compared BDD's delusional and nondelusional variants in 191 subjects using reliable and valid measures that assessed a variety of domains. Subjects with delusional BDD were similar to those with nondelusional BDD in terms of most variables, including most demographic features, BDD characteristics, most measures of functional impairment and quality of life, comorbidity, and family history. Delusional and nondelusional subjects also had a similar probability of remitting from BDD over 1 year of prospective follow-up. However, delusional subjects had significantly lower educational attainment, were more likely to have attempted suicide, had poorer social functioning on several measures, were more likely to have drug abuse or dependence, were less likely to currently be receiving mental health treatment, and had more severe BDD symptoms. However, when controlling for BDD symptom severity, the two groups differed only in terms of educational attainment. These findings indicate that BDD's delusional and nondelusional forms have many more similarities than differences, although on several measures delusional subjects evidenced greater morbidity, which appeared accounted for by their more severe BDD symptoms. Thus, these findings offer some support for the hypothesis that these two BDD variants may constitute the same disorder. Additional studies are needed to examine this issue, which may have relevance for other disorders with both delusional and nondelusional variants in DSM.

Stressful life events as predictors of functioning: findings from the collaborative longitudinal personality disorders study.

OBJECTIVE: Although much attention has been given to the effects of adverse childhood experiences on the development of personality disorders (PDs), we know far less about how recent life events influence the ongoing course of functioning. We examined the extent to which PD subjects differ in rates of life events and the extent to which life events impact psychosocial functioning. METHOD: A total of 633 subjects were drawn from the Collaborative Longitudinal Personality Disorders Study (CLPS), a multi-site study of four personality disorders--schizotypal (STPD), borderline (BPD), avoidant (AVPD), obsessive-compulsive (OCPD)--and a comparison group of major depressive disorders (MDD) without PD. RESULTS: Borderline personality disorder subjects reported significantly more total negative life events than other PDs or subjects with MDD. Negative events, especially interpersonal events, predicted decreased psychosocial functioning over time. CONCLUSION: Our findings indicate higher rates of negative events in subjects with more severe PDs and suggest that negative life events adversely impact multiple areas of psychosocial functioning.

Diet, breakfast, and academic performance in children.

OBJECTIVE: To determine whether nutrient intake and academic and psychosocial functioning improve after the start of a universal-free school breakfast program (USBP). METHODS: Information was gathered from 97 inner city students prior to the start of a USBP and again after the program had been in place for 6 months. Students who had total energy intakes of <50% of the recommended daily allowance (RDA) and/or 2 or more micronutrients of <50% of RDA were considered to be at nutritional risk. RESULTS: Prior to the USBP, 33% of all study children were classified as being at nutritional risk. Children who were at nutritional risk had significantly poorer attendance, punctuality, and grades at school, more behavior problems, and were less likely to eat breakfast at school than children who were not at nutritional risk. Six months after the start of the free school breakfast programs, students who decreased their nutritional risk showed significantly greater: improvements in attendance and school breakfast participation, decreases in hunger, and improvements in math grades and behavior than children who did not decrease their nutritional risk. CONCLUSION: Participation in a school breakfast program enhanced daily nutrient intake and improvements in nutrient intake were associated with significant improvements in student academic performance and psychosocial functioning and decreases in hunger.

Utility of psychosocial screening at a school-based health center.

School-based health centers (SBHC) have substantial potential to improve the recognition and treatment of adolescents' mental health problems. This study was undertaken as a quality improvement project to evaluate utility of the Pediatric Symptom Checklist when completed by youth (PSC-Y) among 383 adolescents seen at a SBHC, and the extent to which identification of psychosocial dysfunction and referral to mental health services improved academic functioning. Adolescents identified by the PSC-Y were significantly more likely to be insured by Medicaid, be a teen-age parent, and to have higher rates of absenteeism and tardiness in comparison to those not identified. Adolescents identified with the PSC-Y who were referred to mental health services significantly decreased their rates of absences and tardiness. Study results provide support for the utility of psychosocial screening and referral in the SBHC environment in facilitating recognition and treatment of adolescent mental health problems and improving student academic functioning.

Use of the Pediatric Symptom Checklist to screen for psychosocial problems in pediatric primary care: a national feasibility study.

BACKGROUND: Routine use of a brief psychosocial screening instrument has been proposed as a means of improving recognition, management, and referral of children's psychosocial morbidity in primary care. OBJECTIVE: To assess the feasibility of routine psychosocial screening using the Pediatric Symptom Checklist (PSC) in pediatrics by using a brief version of the checklist in a large sample representative of the full range of pediatric practice settings in the United States and Canada. We evaluated large-scale screening and the performance of the PSC in detecting psychosocial problems by (1) determining whether the prevalence of psychosocial dysfunction identified by the PSC was consistent with findings in previous, smaller samples; (2) assessing whether the prevalence of positive PSC screening scores varied by population subgroups; and (3) determining whether the PSC was completed by a significant proportion of parents from all subgroups and settings. PATIENTS AND METHODS: Twenty-one thousand sixty-five children between the ages of 4 and 15 years were seen in 2 large primary care networks: the Ambulatory Sentinel Practice Network and the Pediatric Research in Office Settings network, involving 395 pediatric and family practice clinicians in 44 states, Puerto Rico, and 4 Canadian provinces. Parents were asked to complete a brief questionnaire that included demographic information, history of mental health services, the 35-item PSC, and the number of pediatric visits within the past 6 months. RESULTS: The overall prevalence rates of psychosocial dysfunction as measured by the PSC in school-aged and preschool-aged pediatric outpatients (13% and 10%, respectively) were nearly identical to the rates that had been reported in several smaller samples (12%-14% among school-aged children and 7%-14% among preschoolers). Consistent with previous findings, children from low-income families were twice as likely to be scored as dysfunctional on the PSC than were children from higher-income families. Similarly, children from single-parent as opposed to those from 2-parent families and children with a past history of mental health services showed an elevated risk of psychosocial impairment. The current study was the first to demonstrate a 50% increase in risk of impairment for male children. The overall rate of completed forms was 97%, well within an acceptable range, and at least 94% of the parents in each sociodemographic subgroup completed the PSC form. CONCLUSIONS: Use of the PSC offers an approach to the recognition of psychosocial dysfunction that is sufficiently consistent across groups and locales to become part of comprehensive pediatric care in virtually all outpatient settings. In addition to its clinical utility, the consistency and widespread acceptability of the PSC make it well suited for the next generation of pediatric mental health services research, which can address whether earlier recognition of and intervention for psychosocial problems in pediatrics will lead to cost-effective outcomes.

The relationship of school breakfast to psychosocial and academic functioning: cross-sectional and longitudinal observations in an inner-city school sample.

OBJECTIVE: To determine if a relationship exists between participation in a school breakfast program and measures of psychosocial and academic functioning in school-aged children. METHODS: Information on participation in a school breakfast program, school record data, and in-depth interviews with parents and children were collected in 1 public school in Philadelphia, Pa, and 2 public schools in Baltimore, Md, prior to the implementation of a universally free (UF) breakfast program and again after the program had been in place for 4 months. One hundred thirty-three low-income students had complete data before and after the UF breakfast program on school breakfast participation and school-recorded measures, and 85 of these students had complete psychosocial interview data before and after the UF breakfast program. Teacher ratings of behavior before and after the UF breakfast program were available for 76 of these students. RESULTS: Schoolwide data showed that prior to the UF breakfast program, 240 (15%) of the 1627 students in the 3 schools were eating a school-supplied breakfast each day. Of the 133 students in the interview sample, 24 (18%) of the students ate a school-supplied breakfast often, 26 (20%) ate a school-supplied breakfast sometimes, and 83 (62%) ate a school-supplied breakfast rarely or never. Prior to the UF breakfast program, students who ate a school-supplied breakfast often or sometimes had significantly higher math scores and significantly lower scores on child-, parent-, and teacher-reported symptom questionnaires than children who ate a school-supplied breakfast rarely or never. At the end of the school term 4 months after the implementation of the UF breakfast program, school-supplied breakfast participation had nearly doubled and 429 (27%) of the 1612 children in the 3 schools were participating in the school breakfast program each day. In the interview sample, almost half of the children had increased their participation. Students who increased their participation in the school breakfast program had significantly greater increases in their math grades and significantly greater decreases in the rates of school absence and tardiness than children whose participation remained the same or decreased. Child and teacher ratings of psychosocial problems also decreased to a significantly greater degree for children with increased participation in the school breakfast program. CONCLUSION: Both cross-sectional and longitudinal data from this study provide strong evidence that higher rates of participation in school breakfast programs are associated in the short-term with improved student functioning on a broad range of psychosocial and academic measures.

Relationship between hunger and psychosocial functioning in low-income American children.

OBJECTIVE: Using large-scale surveys from nine states, the Community Childhood Hunger Identification Project (CCHIP) estimates that 8% of American children under the age of 12 years experience hunger each year. CCHIP operationalizes child hunger as multiple experiences of parent-reported food insufficiency due to constrained resources. The current study examined the relationship between food insufficiency and school-age, low-income children's psychosocial functioning. The study also assessed the interinformant (parent versus child) reliability and time-to-time reliability of the CCHIP measure. METHOD: Two hundred four school-age children and their parents from four inner-city public schools were interviewed using parent, teacher, and clinician report measures of psychosocial functioning. Ninety-six children and their parents were reinterviewed 4 months later. RESULTS: Hungry and at-risk for hunger children were twice as likely as not-hungry children to be classified as having impaired functioning by parent and child report. Teachers reported higher levels of hyperactivity, absenteeism, and tardiness among hungry/at-risk children than not-hungry children. Parent and child reports of hunger were significantly related to each other, and time-to-time reliability of the CCHIP measure was acceptable. CONCLUSIONS: Results of this study suggest that intermittent experiences of food insufficiency and hunger as measured by CCHIP are associated with poor behavioral and academic functioning in low-income children. The current study also supports the validity and reliability of the CCHIP measure for assessing hunger in children.

The family APGAR and psychosocial problems in children: a report from ASPN and PROS.

BACKGROUND: Our study examined whether the lack of social support as measured by the Family APGAR was related to parents' and physicians' identification of child psychosocial problems and sociodemographic and symptom characteristics of the children screened. METHODS: The parents of 9626 children, ages 4 to 15 years, seen for outpatient medical visits participated in this national study. Parents completed the Family APGAR and the Pediatric Symptom Checklist (PSC), a measure of psychosocial dysfunction. Physicians rated the presence of a new or recurrent psychosocial problem in the child. RESULTS: Children from families with a lack of social support were 4.3 times as likely to receive scores indicating impairment on the PSC and 2.2 times as likely to be identified as having psychosocial problems by physician report. Families with low social support were significantly more likely to report low parental educational achievement, single parent status, and a history of mental health services for the child. Fifty percent of children from families with low social support were identified as having a psychosocial problem by either the PSC or physician rating, or both; however, only 21% of the children identified with psychosocial impairment by these two measures had scores indicating poor family functioning on the Family APGAR. CONCLUSIONS: A lack of family social support is associated with child psychosocial dysfunction as assessed by two different measures. However, the Family APGAR was not a sensitive measure of child psychosocial problems, and thus it supplements, but does not replace, information concerning the child's overall psychosocial functioning.

Localization of a constitutively active, phagocyte-like NADPH oxidase in rabbit aortic adventitia: enhancement by angiotensin II.

Superoxide anion (O2-) plays a key role in the endogenous suppression of endothelium-derived nitric oxide (NO) bioactivity and has been implicated in the development of hypertension. In previous studies, we found that O2- is produced predominantly in the adventitia of isolated rabbit aorta and acts as a barrier to NO. In the present studies, we characterize the enzyme responsible for O2- production in the adventitia and show that this enzyme is a constitutively active NADPH oxidase with similar composition as the phagocyte NADPH oxidase. Constitutive O2--generating activity was localized to aortic adventitial fibroblasts and was enhanced by the potent vasoconstrictor angiotensin II. Immunohistochemistry of aortic sections demonstrated the presence of p22(phox), gp91(phox), p47(phox), and p67(phox) localized exclusively in rabbit aortic adventitia, coincident with the site of staining for O2- production. Furthermore, immunodepletion of p67(phox) from adventitial fibroblast particulates resulted in the loss of NADPH oxidase activity, which could be restored by the addition of recombinant p67(phox). Further study into the regulation of this adventitial source of O2- is important in elucidating the mechanisms regulating the bioactivity of NO and may contribute to our understanding of the pathogenesis of hypertension.
