Comparing the effectiveness of home visiting paraprofessionals and mental health professionals delivering a postpartum depression preventive intervention: a cluster-randomized non-inferiority clinical trial

To determine whether pregnant women receiving the Mothers and Babies group–based intervention exhibited greater depressive symptom reductions and fewer new cases of major depression than women receiving usual community-based services, and to examine whether groups run by paraprofessional home visitors and mental health professionals yielded similar depressive symptom reductions and prevention of major depression. Using a cluster-randomized design, 37 home visiting programs were randomized to usual home visiting, Mothers and Babies delivered via home visiting paraprofessionals, or Mothers and Babies delivered via mental health professionals. Baseline assessments were conducted prenatally with follow-up extending to 24 weeks postpartum. Eligibility criteria were ≥ 16 years old, ≤ 33 gestation upon referral, and Spanish/English speaking. Depressive symptoms at 24 weeks postpartum was the primary outcome. Eight hundred seventy-four women were enrolled. Neither intervention arm was superior to usual care in decreasing depressive symptoms across the sample (p = 0.401 home visiting paraprofessional vs. control; p = 0.430 mental health professional vs. control). Post hoc analyses suggest a positive intervention effect for women exhibiting mild depressive symptoms at baseline. We have evidence of non-inferiority, as the model-estimated mean difference in depressive symptoms between intervention arms (0.01 points, 95% CI: −0.79, 0.78) did not surpass our pre-specified margin of non-inferiority of two points. Although we did not find statistically significant differences between intervention and control arms, non-inferiority analyses found paraprofessional home visitors generated similar reductions in depressive symptoms as mental health professionals. Additionally, Mothers and Babies appears to reduce depressive symptoms among women with mild depressive symptoms when delivered by mental health professionals. This trial is registered on ClinicalTrials.gov (initial post: December 1, 2016; identifier: NCT02979444).

     

Unusual presentation of a Stafne bone cyst

Mandibular radiolucencies are present in a variety of situations. These fall into developmental, metabolic, traumatic, infectious, and neoplastic categories. Differential diagnosis of these "lesions" is arrived at through signs, symptoms, history, radiographic presentation, and other diagnostic tools. This article presents the case of a 77-year-old man with an unusual radiographic presentation of the left posterior mandible.     

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.     

The Effects of the Going Places Program on Early Adolescent Substance Use and Antisocial Behavior

This study evaluated the effects of a school-based intervention on growth trajectories of smoking, drinking, and antisocial behavior among early adolescents. Seven middle schools were randomized to intervention or comparison conditions and students in two successive cohorts (n = 1484) provided five waves of data from sixth to ninth grade. The Going Places Program, included classroom curricula, parent education, and school environment components. Latent growth curve analyses demonstrated significant treatment group effects, including reducing increases in friends who smoke, outcome expectations for smoking, and smoking progression, but had non-significant effects on drinking or antisocial behavior. The Going Places Program was effective in preventing increases in smoking progression, but its efficacy as a more cross-cutting problem behavior preventive intervention was not confirmed.     

Impact of Multifocality and Multilocation of Positive Surgical Margin After Radical Prostatectomy on Predicting Oncological Outcome

Objective

To assess the impact of focality and location of positive surgical margins (PSM) on long-term outcomes after radical prostatectomy (RP) for prostate cancer (PCa), including biochemical recurrence (BCR), metastasis and overall mortality.

Intellectual and Developmental Status in Children With Hyperphenylalaninemia and PKU Who Were Screened in a National Program

Background:

Hyperphenylalaninemia (HPA) and Phenylkeonuria (PKU) are metabolic errors caused by deficiency of phenylalanine hydroxylase enzyme, which results in increased level of phenylalanine. This increase is toxic to the growing brain.

Objectives:

The purpose of this study was to compare the intellectual and developmental status in HPA and PKU children with normal population in national screening program.

Patients and Methods:

In a historical cohort study, 41 PKU patients who had the inclusion criteria and 41 healthy children were evaluated. Wechsler preschool and primary scale of intelligence-3rd edition (WPPI-3) was used in order to assess the intellectual status of children 4 years and older and Ages and stages questionnaire (ASQ) was used to assess the developmental status of children 5 years and younger.

Results:

In intellectual test comparison, the two groups showed significant difference in Wechsler’s performance intelligence score and some performance subscales (P-value < 0.01). In comparison of developmental status, no significant difference was observed between the two groups (P-value > 0.05).

Conclusions:

Even with early diagnosis and treatment of PKU patients, these children show some deficiencies intellectually compared to normal children. This study emphasizes on necessity for screening intellectual and developmental status of PKU patients so that effective medical or educational measures can taken in case of deficiencies.     

Temperature homeostasis in transgenic mice lacking thyroid hormone receptor-alpha gene products

We studied temperature homeostasis in male mice lacking all thyroid hormone receptor-alpha gene products (TRalpha-0/0). As other TRalpha-deficient mice, TRalpha-0/0 mice have lower core body temperature (T(C)) than cognate wild-type controls. We found that obligatory thermogenesis is normal in TRalpha-0/0 and that the lower T(C) at room temperature (RT, 20-22 C) is caused by a down setting of the hypothalamic thermostat. However, TRalpha-0/0 mice are cold intolerant due to impaired facultative thermogenesis. Norepinephrine-induced brown adipose tissue (BAT) thermogenesis is blunted, even though BAT-relevant genes and T(4) deiodinase respond normally to cold stimulation, as do serum T(3), serum glycerol (marker of lipolysis), and heart rate. BAT normally contributes to maintain T(C) at RT, 9 C below thermoneutrality, yet TRalpha-0/0 mice do not show signs of being cold stressed at 20-22 C. Instead, oxygen consumption is greater in TRalpha-0/0 than in wild-type mice at RT, suggesting the recruitment of an alternate, cold-activated form of thermogenesis to compensate for the lack of BAT thermogenesis. These results indicate that TRalpha is necessary for T(3) to modulate the central control of T(C) and for an essential step in norepinephrine activation of BAT thermogenesis but not to sustain obligatory thermogenesis. In addition, the results provide evidence for an alternate form of facultative thermogenesis, which probably originates in skeletal muscle and that is less effective and more energy demanding than BAT thermogenesis.
