BACKGROUND: Antipsychotic prescribing for youth has increased rapidly, is linked with serious health concerns, and lacks clear measures of quality for pediatric care. We reviewed treatment guidelines relevant to 7 quality concepts for appropriate use and management of youth on antipsychotics: 1) use in very young children, 2) multiple concurrent antipsychotics, 3) higher-than-recommended doses, 4) use without a primary indication, 5) access to psychosocial interventions, 6) metabolic screening, and 7) follow-up visits with a prescriber. METHODS: We searched for clinical practice guidelines meeting the following criteria: developed or endorsed by a national body, published after 2000, and specific treatment recommendations made related to 1 or more of the 7 quality concepts. Sources included electronic databases, the American Academy of Child and Adolescent Psychiatry Web site, and stakeholder and expert advisory committee recommendations. Two raters reviewed the 11 guidelines identified, extracting treatment recommendations, including details that could support measure definitions, and ratings of strength of recommendation and evidence. RESULTS: All 7 quality concepts were strongly endorsed by 1 or more guidelines, and 2 or more guidelines assigned their highest strength of recommendation ratings to 6 of the 7 concepts. Two guidelines rated evidence, providing high strength of evidence for 2 quality concepts: psychosocial interventions and metabolic monitoring. CONCLUSIONS: Guidelines provide support for 7 quality concepts addressing antipsychotic prescribing for youth. However, guideline support is often based on strong clinical consensus rather than a robust evidence base.

Emotion plays a critical role in cognition and goal-directed behavior via complex interconnections between the emotional and motivational systems. It has been hypothesized that the impairment in goal-directed behavior widely noted in schizophrenia may result from defects in the interaction between the neural (ventral) emotional system and (rostral) cortical processes. The present study examined the impact of emotion on attention and memory in schizophrenia. Twenty-five individuals with schizophrenia related psychosis and 25 healthy control subjects were administered a computerized task in which they were asked to search for target images during a Rapid Serial Visual Presentation of pictures. Target stimuli were either positive or negative, or neutral images presented at either 200ms or 700ms lag. Additionally, a visual hedonic task was used to assess differences between the schizophrenia group and controls on ratings of valence and arousal from the picture stimuli. Compared to controls, individuals with schizophrenia detected fewer emotional images under both the 200ms and 700ms lag conditions. Multivariate analyses showed that the schizophrenia group also detected fewer positive images under the 700ms lag condition and fewer negative images under the 200ms lag condition. Individuals with schizophrenia reported higher pleasantness and unpleasantness ratings than controls in response to neutral stimuli, while controls reported higher arousal ratings for neutral and positive stimuli compared to the schizophrenia group. These results highlight dysfunction in the neural modulation of emotion, attention, and cortical processing in schizophrenia, adding to the growing but mixed body of literature on emotion processing in the disorder.

A large theoretical and empirical literature documents the central role of familismo (i.e., a strong emphasis on family) in the functioning of Latino youth. Few studies, however, have examined its association with early childhood functioning. The present study explored the potential risk and protective effects of maternal familismo on the adaptive and mental health functioning of 4 - 5 year old Latino children. A sample of 205 Mexican and 147 Dominican immigrant families was recruited from New York City. Mothers reported on their level of familismo, and acculturative status. Mothers and teachers rated child adaptive behavior and internalizing and externalizing problems. Findings suggest that maternal familismo is not uniformly associated with positive or negative early developmental outcomes but that its effects are moderated by child gender, family poverty and cultural (e.g., maternal ethnic and US American identity) characteristics. In addition, different mechanisms were identified for each ethnic group. Familismo was associated both positively (for boys) and negatively (for poor children) with adaptive behavior in the Mexican American sample. In the Dominican American sample, familismo showed a wide range of positive, albeit moderated, effects. Prevention efforts that help parents critically evaluate the impact of familismo on family processes, and preserve those manifestations of familismo that are protective, may best promote Latino child well-being.

Despite high rates of trauma exposure (46%-96%) and significant posttraumatic stress disorder (PTSD; 21%-29%) symptoms in adolescent psychiatric inpatients, there is a dearth of research on effective interventions delivered in inpatient settings. The current report describes the development of Brief STAIR-A, a repeatable 3-module version of skills training in affective and interpersonal regulation (STAIR) developed for adolescents in inpatient care. An uncontrolled design was used to conduct a preliminary examination of the group intervention's effectiveness. Adolescent psychiatric inpatients (N = 38; ages 12 years-17 years) admitted to a public hospital participated in Brief STAIR-A and attended a median of 6 sessions (range 3-36). They completed measures of PTSD and depressive symptom severity, coping skill use, and coping efficacy upon admission and again prior to discharge. Participants reported significant reductions in symptom severity (d = 0.65-0.67), no change in the absolute level of coping skills used (d = 0.16), but greater coping efficacy when discharged from care (d = 0.75). Results from this pilot study suggest that this brief group treatment shows promise for treating adolescents' trauma-related difficulties in inpatient psychiatry settings, but additional research examining its effectiveness is essential.

This study examined proximal risk and protective factors that contribute to academic achievement among 130 Latino students. Participating students were 56.2% female and 35.3% foreign-born (mean age = 11.38, SD = .59). Acculturative stress, immigrant status, child gender, parental monitoring, traditional cultural values, mainstream values, and English language proficiency were explored in relation to academic achievement. Higher levels of parental monitoring, English language proficiency, and female gender were associated with higher grades, while mainstream values were associated with lower grades. In addition, a significant interaction between acculturative stress and immigrant status was found, such that higher acculturative stress was related to poorer grades for U.S.-born students in particular. Thus, parental monitoring and female gender are potential protective factors, while identification with mainstream values and low English language proficiency are risk factors for poor grades. U.S.-born students may be particularly vulnerable to the effects of acculturative stress.

Patterns of neural activity are critical for sculpting the immature brain, and disrupting this activity is believed to underlie neurodevelopmental disorders [1-3]. Neural circuits undergo extensive activity-dependent postnatal structural and functional changes [4-6]. The different forms of neural plasticity [7-9] underlying these changes have been linked to specific patterns of spatiotemporal activity. Since maternal behavior is the mammalian infant's major source of sensory-driven environmental stimulation and the quality of this care can dramatically affect neurobehavioral development [10], we explored, for the first time, whether infant cortical activity is influenced directly by interactions with the mother within the natural nest environment. We recorded spontaneous neocortical local field potentials in freely behaving infant rats during natural interactions with their mother on postnatal days approximately 12-19. We showed that maternal absence from the nest increased cortical desynchrony. Further isolating the pup by removing littermates induced further desynchronization. The mother's return to the nest reduced this desynchrony, and nipple attachment induced a further reduction but increased slow-wave activity. However, maternal simulation of pups (e.g., grooming and milk ejection) consistently produced rapid, transient cortical desynchrony. The magnitude of these maternal effects decreased with age. Finally, systemic blockade of noradrenergic beta receptors led to reduced maternal regulation of infant cortical activity. Our results demonstrate that during early development, mother-infant interactions can immediately affect infant brain activity, in part via a noradrenergic mechanism, suggesting a powerful influence of the maternal behavior and presence on circuit development.

BACKGROUND: Questions remain regarding the sustainment of evidence-based practices following implementation. The present study examined the sustainment of community clinicians' implementation (i.e., penetration) of cognitive-behavioral therapy, attitudes toward evidence-based practices, and knowledge of cognitive-behavioral therapy for youth anxiety two years following training and consultation in cognitive-behavioral therapy for youth anxiety. METHODS: Of the original 115 participants, 50 individuals (43%) participated in the two-year follow-up. A t- test examined sustainment in penetration over time. Hierarchical linear modeling examined sustainment in knowledge and attitudes over time. Time spent in consultation sessions was examined as a potential moderator of the change in knowledge and attitudes. RESULTS: Findings indicated sustained self-reported penetration of cognitive-behavioral therapy for anxious youth, with low fidelity to some key CBT components (i.e., exposure tasks). Follow-up knowledge was higher than at baseline but lower than it had been immediately following the consultation phase of the study. Belief in the utility of evidence-based practices was sustained. Willingness to implement an evidence-based practice if required to do so, appeal of evidence-based practices, and openness toward evidence-based practices were not sustained. Participation in consultation positively moderated changes in knowledge and some attitudes. CONCLUSIONS: Sustainment varied depending on the outcome examined. Generally, greater participation in consultation predicted greater sustainment. Implications for future training include higher dosages of consultation.

The major aim of surgeons has always been a minimalist approach towards surgery, thereby reducing the complications associated with the surgery. The gold standard treatment for cholelithiasis with cholecystitis is currently the four port laparoscopic cholecystectomy (4 PLC). Recently, a newer technique has been introduced which uses a single port, rather than the four ports, for the removal of the gall bladder laparoscopically; it is known as Single Incision Laparoscopic Cholecystectomy (SILC). This is a comparatively minimal approach towards surgery. Therefore the purpose of this review is to compare the advantages and the disadvantages of SILC versus 4PLC, and hence, to give an idea of whether SILC is ready to replace the traditional approach as the new treatment of choice.
