PURPOSEnTo quantify the prevalence of prescribed opioid analgesics among pregnant women enrolled in Tennessee Medicaid from 1995 to 2009.nnnMETHODSnRetrospective cohort study of 277,555 pregnancies identified from birth and fetal death certificates, and linked to previously validated, computerized pharmacy records. Poisson regression was used to estimate trends over time, rate ratios, and 95% confidence intervals (CI).nnnRESULTSnDuring the study period, 29% of pregnant women filled a prescription for an opioid analgesic. From 1995 to 2009, any pregnancy-related use increased 1.90-fold (95% CI, 1.83-1.98), first trimester use increased 2.27-fold (95% CI, 2.14-2.41), and second or third trimester use increased 2.02-fold (95% CI, 1.93-2.12), after adjusting for maternal characteristics. Any pregnancy-related, first trimester, and second or third trimester use were each more likely among mothers who were at least 21 years old, white, non-Hispanic, prima gravid, resided in nonurban areas, enrolled in Medicaid owing to disability, and who had less than a high school education.nnnCONCLUSIONSnOpioid analgesic use by Tennessee Medicaid-insured pregnant women increased nearly 2-fold from 1995 to 2009. Additional study is warranted to understand the implications of this increased use.

BACKGROUNDnLittle is known about the extent of antiepileptic drug (AED) use in pregnancy, particularly for newer agents. Our objective was to assess whether AED use has increased among pregnant women in the US, 2001-2007.nnnMETHODSnu2002 We analysed data from the Medication Exposure in Pregnancy Risk Evaluation Program (MEPREP) database, 1 January 2001 to 31 December 2007. We identified liveborn deliveries among women, aged 15-45 years on delivery date, who were members of MEPREP health plans (n=585615 deliveries). Pregnancy exposure to AEDs, determined through outpatient pharmacy dispensing files. Older AEDs were available for clinical use before 1993; other agents were considered newer AEDs. Information on sociodemographic and medical/reproductive factors was obtained from linked birth certificate files. Maternal diagnoses were identified based on ICD-9 codes.nnnRESULTSnu2002 Prevalence of AED use during pregnancy increased between 2001 (15.7 per 1000 deliveries) and 2007 (21.9 per 1000 deliveries), driven primarily by a fivefold increase in the use of newer AEDs. Thirteen per cent of AED-exposed deliveries involved a combination of two or more AEDs. Psychiatric disorders were the most prevalent diagnoses, followed by epileptic and pain disorders, among AED users regardless of AED type, year of conception or gestational period.nnnCONCLUSIONSnu2002 AED use during pregnancy increased between 2001 and 2007, driven by a fivefold increase in the use of newer AEDs. Nearly one in eight AED-exposed deliveries involved the concomitant use of more than one AED. Additional investigations of the reproductive safety of newer AEDs may be needed.

Quality of life for veterans and servicemembers with major traumatic limb loss from Vietnam and OIF/OEF conflicts

Richard A. Epstein; Allen W. Heinemann; Lynne V. McFarland

The goals of rehabilitation after major limb loss include not only functional restoration but also a return to a high quality of life (QOL). Few studies have identified which factors are associated with QOL in veterans and servicemembers with combat-associated major limb loss. We enrolled Vietnam and Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) veterans and servicemembers in a national survey on prosthetic device use. In the Vietnam group, multivariate analysis found multiple limb loss (adjusted odds ratio [aOR] = 3.1, 95% confidence interval [CI] = 1.57-6.02) and satisfaction with current prostheses (aOR = 1.2, 95% CI = 1.05-1.38) are associated with better overall QOL, while a higher amputation impact rank (aOR = 0.66, 95% CI = 0.59-0.74) and depression (aOR = 0.21, 95% CI = 0.08-0.54) are associated with worse overall QOL. In the OIF/OEF group, three factors are significantly associated with worse overall QOL: combat-associated head injury (aOR = 0.78, 95% CI = 0.61-0.99), combat-associated injury to the nonamputated limb (aOR = 0.71, 95% CI = 0.57-0.88), and assistance needed in daily living (aOR = 0.12, 95% CI = 0.02-0.72). Improving satisfaction with prosthetic devices, improving mental health care, and treating other combat-associated injuries may significantly improve the overall QOL for these veterans and servicemembers.

Psychosocial Interventions for Child Disruptive Behaviors: A Meta-analysis

Richard A. Epstein; Christopher Fonnesbeck; Shannon A Potter; Katherine Rizzone; Melissa L McPheeters

BACKGROUND: Disruptive behavior disorders are among the most common child and adolescent psychiatric disorders and associated with significant impairment. OBJECTIVE: Systematically review studies of psychosocial interventions for children with disruptive behavior disorders. METHODS: We searched Medline (via PubMed), Embase, and PsycINFO. Two reviewers assessed studies against predetermined inclusion criteria. Data were extracted by 1 team member and reviewed by a second. We categorized interventions as having only a child component, only a parent component, or as multicomponent interventions. RESULTS: Sixty-six studies were included. Twenty-eight met criteria for inclusion in our meta-analysis. The effect size for the multicomponent interventions and interventions with only a parent component had the same estimated value, with a median of −1.2 SD reduction in outcome score (95% credible interval, −1.6 to −0.9). The estimate for interventions with only a child component was −1.0 SD (95% credible interval, −1.6 to −0.4). LIMITATIONS: Methodologic limitations of the available evidence (eg, inconsistent or incomplete outcome reporting, inadequate blinding or allocation concealment) may compromise the strength of the evidence. Population and intervention inclusion criteria and selected outcome measures eligible for inclusion in the meta-analysis may limit applicability of the results. CONCLUSIONS: The 3 intervention categories were more effective than the control conditions. Interventions with a parent component, either alone or in combination with other components, were likely to have the largest effect. Although additional research is needed in the community setting, our findings suggest that the parent component is critical to successful intervention.

Predictors of Residential Placement Following a Psychiatric Crisis Episode Among Children and Youth in State Custody

Jung Min Park; Neil Jordan; Richard A. Epstein; David S. Mandell; John S. Lyons

This study examined the extent and correlates of entry into residential care among 603 children and youth in state custody who were referred to psychiatric crisis services. Overall, 27% of the sample was placed in residential care within 12 months after their 1st psychiatric crisis screening. Among the children and youth placed in residential care, 51% were so placed within 3 months of their 1st crisis screening, with an additional 22% placed between 3 and 6 months after screening. Risk behavior and functioning, psychiatric hospitalization following screening, older age, placement type, and caregivers capacity for supervision were associated with increased residential placement. The findings highlight the importance of early identification and treatment of behavior and functioning problems following a crisis episode among children and youth in state custody to reduce the need for subsequent residential placement. Having an inpatient psychiatric episode following a crisis episode places children at greater risk for residential placement, suggesting that the hospital is an important point for diversion programs. Children and youth in psychiatric crisis may also benefit from efforts to include their families in the treatment process.

Olanzapine monotherapy for acute depression in patients with bipolar I or II disorder: results of an 8-week open label trial

William V. Bobo; Richard A. Epstein; Richard C. Shelton

We evaluated the efficacy, tolerability, and safety of olanzapine monotherapy in 20 adult patients with bipolar I or II disorder, depressed phase. Patients received open‐label olanzapine monotherapy (mean modal dose, 15u2009mg/day) for 8 weeks. Assessments of psychopathology (Montgomery–Asberg Depression Rating Scale [MADRS], Quick Inventory of Depressive Symptomatology [QIDS‐SR‐16], Young Mania Rating Scale [YMRS]), clinical global state (Clinical Global Impressions [CGI] scale), and safety/tolerability were performed at baseline, and at 1, 2, 4, 6, and 8 weeks. Seventeen patients (85.0%) completed the study. Improvement in MADRS total scores was observed after the first week of treatment, and at all remaining follow‐up time points (pu2009≤u20090.005). Parallel improvement in QIDS‐SR‐16 (pu2009<u20090.001) and CGI‐Severity (pu2009<u20090.001) was observed between baseline and study endpoint. Nine (45%) subjects achieved positive treatment response, eight of whom (40%) also achieved symptom remission. There were significant increases in weight (+3.2u2009kg, pu2009=u20090.001) and body mass index (+1.1u2009kg/m2, pu2009=u20090.001), but not fasting glucose or lipids, with the exception of reduced triglyceride levels in the overall sample, and reduced HDL cholesterol in females. Olanzapine may be an effective, well‐tolerated option for treating acute non‐psychotic depression across a variety of bipolar disorder subtypes. Copyright

Treatment of bipolar disorders during pregnancy: maternal and fetal safety and challenges.

Richard A. Epstein; Katherine M. Moore; William V. Bobo

Treating pregnant women with bipolar disorder is among the most challenging clinical endeavors. Patients and clinicians are faced with difficult choices at every turn, and no approach is without risk. Stopping effective pharmacotherapy during pregnancy exposes the patient and her baby to potential harms related to bipolar relapses and residual mood symptom-related dysfunction. Continuing effective pharmacotherapy during pregnancy may prevent these occurrences for many; however, some of the most effective pharmacotherapies (such as valproate) have been associated with the occurrence of congenital malformations or other adverse neonatal effects in offspring. Very little is known about the reproductive safety profile and clinical effectiveness of atypical antipsychotic drugs when used to treat bipolar disorder during pregnancy. In this paper, we provide a clinically focused review of the available information on potential maternal and fetal risks of untreated or undertreated maternal bipolar disorder during pregnancy, the effectiveness of interventions for bipolar disorder management during pregnancy, and potential obstetric, fetal, and neonatal risks associated with core foundational pharmacotherapies for bipolar disorder.

Treatment of Ankyloglossia for Reasons Other Than Breastfeeding: A Systematic Review

Sivakumar Chinnadurai; David O. Francis; Richard A. Epstein; Anna Morad; Sahar Kohanim; Melissa L McPheeters

BACKGROUND AND OBJECTIVE: Children with ankyloglossia, an abnormally short, thickened, or tight lingual frenulum, may have restricted tongue mobility and sequelae, such as speech and feeding difficulties and social concerns. We systematically reviewed literature on feeding, speech, and social outcomes of treatments for infants and children with ankyloglossia. METHODS: Medline, PsycINFO, Cumulative Index of Nursing and Allied Health Literature, and Embase were searched. Two reviewers independently assessed studies against predetermined inclusion/exclusion criteria. Two investigators independently extracted data on study populations, interventions, and outcomes and assessed study quality. RESULTS: Two randomized controlled trials, 2 cohort studies, and 11 case series assessed the effects of frenotomy on feeding, speech, and social outcomes. Bottle feeding and social concerns, such as ability to use the tongue to eat ice cream and clean the mouth, improved more in treatment groups in comparative studies. Supplementary bottle feedings decreased over time in case series. Two cohort studies reported improvement in articulation and intelligibility with treatment. Other benefits were unclear. One randomized controlled trial reported improved articulation after Z-frenuloplasty compared with horizontal-to-vertical frenuloplasty. Numerous noncomparative studies reported speech benefits posttreatment; however, studies primarily discussed modalities, with outcomes including safety or feasibility, rather than speech. We included English-language studies, and few studies addressed longer-term speech, social, or feeding outcomes; nonsurgical approaches, such as complementary and alternative medicine; and outcomes beyond infancy, when speech or social concerns may arise. CONCLUSIONS: Data are currently insufficient for assessing the effects of frenotomy on nonbreastfeeding outcomes that may be associated with ankyloglossia.

Treatment of nonpsychotic major depression during pregnancy: Patient safety and challenges

Richard A. Epstein; Katherine M. Moore; William V. Bobo

In pregnant women with major depression, the overarching goal of treatment is to achieve or maintain maternal euthymia, thus limiting both maternal and fetal exposure to the harmful effects of untreated or incompletely treated depression. However, the absence of uniformly effective therapies with guaranteed obstetric and fetal safety makes the treatment of major depression during pregnancy among the most formidable of clinical challenges. Clinicians and patients are still faced with conflicting data and expert opinion regarding the reproductive safety of antidepressants in pregnancy, as well as large gaps in our understanding of the effectiveness of most antidepressants and nonpharmacological alternatives for treating antenatal depression. In this paper, we provide a clinically focused review of the available information on potential maternal and fetal risks of untreated maternal depression during pregnancy, the effectiveness of interventions for maternal depression during pregnancy, and potential obstetric, fetal, and neonatal risks associated with antenatal antidepressant use.
