Heritability and clinical features of multigenerational families with obsessive-compulsive disorder and hoarding.

To date, only one complete genome screen for obsessive-compulsive disorder (OCD) has been published. That study identified a region of suggestive linkage (maximum lod score of 2.25) with a relatively small sample size (N = 56; 27 with OCD). Additional complete genome screens are needed to confirm this finding and identify other regions of linkage. We present the clinical characteristics and power to detect linkage of 11 multigenerational families with OCD and hoarding (N = 92; 44 with OCD), as well as heritability estimates for several quantitative traits. Families with at least two individuals with OCD were identified through probands with childhood-onset OCD. Expected lod scores were calculated for simulated genetic marker data under an additive and two dominant models assuming a dense SNP marker map. All affected individuals had an early age of onset (18 or younger). Hoarding was present in 46% of subjects. Obsessive-compulsive symptoms and hoarding were highly heritable. The maximum mean expected lod score was 3.31 for OCD and 1.39 for hoarding. We found reasonable power to detect regions of interest (lod = 2) for OCD in these families, but will need to expand our family collection to have adequate power to detect regions of interest for hoarding.     

Umbilical cord blood screening for cytomegalovirus DNA by quantitative PCR.

BACKGROUND: Cytomegalovirus (CMV) infection, which is the most common congenitally transmitted infection, affects approximately 1% of neonates worldwide. Despite its prevalence, no convenient screening test for neonatal CMV infection has been implemented. OBJECTIVE: The purpose of this pilot study was to evaluate the feasibility and yield of screening umbilical cord blood for CMV DNA emiaby quantitative PCR. STUDY DESIGN: Umbilical cord blood was tested for CMV DNAemia using a commercial quantitative PCR assay. Maternal CMV serostatus at the time of delivery was assessed by testing for CMV IgG and IgM antibodies in serum. CONCLUSIONS: Screening for congenital CMV infection with PCR is easily incorporated into routine labor and delivery care using discarded cord blood specimens to identify neonates whose infection is otherwise undiagnosed. Among 433 infants tested, two (0.5%) had DNAemia detected in cord blood, one of whom was symptomatic, and both of whose mothers were CMV IgG positive and IgM negative. Viremic neonates identified by screening with PCR may be at high risk of developing long-term neurological complications of CMV infection and cannot reliably be identified using clinical presentation or maternal serology. Because of its convenience, cord blood CMV screening with PCR should be further investigated for incorporation into neonatal screening protocols.

Social–Emotional Profiles of PTSD,Complex PTSD,and Borderline Personality Disorder Among Racially and Ethnically Diverse Young Adults: A Latent Class Analysis

The debate around the construct validity of complex posttraumatic stress disorder (CPTSD) has begun to examine whether CPTSD diverges from posttraumatic stress disorder (PTSD) when it co‐occurs with the diagnosis of borderline personality disorder (BPD). The present study (a) examined the construct validity of CPTSD through a latent class analysis of a non–treatment‐seeking sample of young trauma‐exposed adults and (b) characterized each class in terms of trauma characteristics, social emotions (e.g., shame, guilt, blame), and interpersonal functioning. A total of 23 dichotomized survey items were chosen to represent the symptoms of PTSD, CPTSD, and BPD and administered to 197 trauma‐exposed participants. Fit statistics compared models with 2–4 latent classes. The four‐class model showed the best fit statistics and clinical interpretability. Classes included a “high PTSD+CPTSD+BPD” class, characterized by high‐level endorsement of all symptoms for the three diagnoses; a “moderate PTSD+CPTSD+BPD” class, characterized by endorsement of some symptoms across all three diagnoses; a “PTSD” class, characterized by endorsement of the ICD‐11 PTSD criteria; and a “healthy” class, characterized by low symptom endorsement overall. Pairwise comparisons showed individuals in the high PTSD+CPTSD+BPD class to have the highest levels of psychological distress, traumatic event history, adverse childhood experiences, and PTSD symptoms. Shame was the only social emotion to significantly differ between the classes, p = .002, η² = .16. The findings diverge from the literature, indicating an overlap of PTSD, CPTSD, and BPD symptoms in a non–treatment‐seeking community sample. Further, shame may be a central emotion that differentiates between presentation severities following trauma exposure.     

Short-term chemoprophylaxis with ceftizoximevs. Five-day aminoglycoside with metronidazole in ‘contaminated’ lower gastrointestinal surgery

In a prospective, open, randomized controlled trial, 173 patients requiring surgery for potentially contaminated lower gastrointestinal surgery were allocated to receive either two doses of ceftizoxime (2 gm) with one dose of metronidazole (1.5 gm) or gentamicin 3 mg/kg/day for five days with one dose of metronidazole (1.5 gm). Eighty-nine patients received ceftizoxime and 84 patients received gentamicin. The groups were comparable with respect to diagnosis, procedure, type of anastomosis, and wound closure. The incidence of withdrawal due to failure to respond to the study drug (11.5 percent) was equivalent in the two groups. There was no difference in the overall incidence of postsurgical infection between the ceftizoxime and metronidazole group (22.2 percent) and the gentamicin and metronidazole group (25.7 percent). The incidence of wound infection (ceftizoxime and metronidazole, 6.9 percent; gentamicin and metronidazole, 10 percent) and deep sepsis (ceftizoxime and metronidazole, 15.3 percent; gentamicin and metronidazole, 15.7 percent) was similar.     

The Massachusetts Behavioral Health Program Year 5: Transition to a New Managed Care Organization

Year 5 of the Massachusetts Behavioral Health Program was a transition to management by a new private managed care organization. Fifty-eight providers interviewed for an ongoing panel survey reported slightly lower levels of quality, access, utilization, and length of stay than a year earlier. Relationships with providers and advocates improved after an initial difficult period, while consumer and family involvement at all levels remained low. The greatest changes in managed care appeared to take place during the initial transition from fee-for-service care, but intractable problems continue, and full participation of stakeholders seems difficult to achieve.     

Studentschool bonding and adolescent problem behavior

Adolescent problem behavior, including substance use, schoolmisconduct and delinquency, is a national concern. Implicitin the concept of middle school is the recognition that studentswho develop positive social bonds with their school are morelikely to perform well academically, and refrain from misconductand other antisocial behavior. However, little scientific attentionhas been given to the complex interactions between middle schoolstudents and the school environment. Prior to implementing amiddle school problem behavior prevention program we conducteda survey in the seven middle schools in one US school district.Out of 4668 grade 6–8 students enrolled, 4263 (91.3%)completed the survey. Student–school bonding was positivelycorrelated with school adjustment (r = 0.49) and perceived schoolclimate (r = 0.77), but inversely correlated with problem behavior(r = –0.39 to –0.43). Problem behavior was significantlyhigher (P < 0.001) among males than females and among studentsin higher grades. Conversely, school bonding, climate and adjustmentwere significantly higher (P < 0.001) among females thanmales, but declined significantly from one grade to the next.The data support the conclusion that school bonding is associatedwith problem behavior. We describe the development of a multiple-componentintervention in middle schools designed to increase student–schoolbonding and prevent problem behavior.
