Abstract
AIMS The primary objective of the SmartSenior@home study was to examine the acceptance of the SmartSenior system by older adults. METHODS Twenty-eight partners from industry and research, including the health care sector, worked collaboratively to implement services aiming to maximize independence in old age. The prospective cohort study was conducted in Potsdam, Germany, with n = 35 older adults between 55 and 88 years of age in their apartments. All participants underwent extensive pre- and post-study visits with in-home interviews, functional assessments for cognition, fine motor skills, and mobility as well as responding to questionnaires on user acceptance and quality of life. RESULTS The results indicate moderate-to-high user acceptance for the SmartSenior system. In particular, the services for general assistance and health, such as audio/video communication, blood pressure monitoring, and communication with a health professional, were rated as very attractive. Less used and less accepted services were those promoting social interaction and reminder services. CONCLUSION Besides reliable functioning of the SmartSenior system, the availability of a confidant seems to be the most significant acceptance factor. As one conclusion of this trial, it is possible to develop, integrate, and test an infrastructure for ambient assisted living services in real life.

Functional impairment and mental health functioning among Vietnamese children. Soc Psychiatry Psychiatr Epidemiol 2016; 51:39-47. [PMID: 26315942 PMCID: PMC4724307 DOI: 10.1007/s00127-015-1114-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2015] [Accepted: 08/12/2015] [Indexed: 01/13/2023]
Abstract
PURPOSE Functional impairment is a key indicator of need for mental health services among children and adolescents, often a stronger predictor of service usage than mental health symptoms themselves. Functional impairment may be of particular importance in low- and middle-income countries (LMIC) because of its potential to focus policy on treatment of child mental health problems which is generally given low priority in LMIC. However, few studies have assessed functional impairment in LMIC. The present study assessed rates of functional impairment among children in Vietnam, as a case example of an LMIC, as well as effects of other risk/protective factors of particular relevance to LMIC (e.g., whether the family lived in an urban or rural area; family structure variables such as grandparents living with the family). METHODS 1314 parents of children 6-16 years old from 10 Vietnamese provinces were interviewed. RESULTS The overall rate of functional impairment among Vietnamese children was 20 %, similar to rates in high-income countries such as Germany and the United States, suggesting that LMIC status may not be associated with dramatic increases in functional impairment in children. Functional impairment was significantly greater among mental health cases than non-cases, with increases of over 550 % associated with mental health caseness. A number of other risk factors (e.g., marital status) had smaller but significant effects. CONCLUSIONS Mental health problems are a major but not the sole contributor to functional impairment among Vietnamese children. The pragmatic significance of this research lies in its potential to affect public awareness and policy related to child mental health in LMIC.

Abstract
The global burden of neurological, neuropsychiatric, substance-use and neurodevelopmental disorders in low- and middle-income countries is worsened, not only by the lack of targeted research funding, but also by the lack of relevant in-country research capacity. Such capacity, from the individual to the national level, is necessary to address the problems within a local context. As for many health issues in these countries, the ability to address this burden requires development of research infrastructure and a trained cadre of clinicians and scientists who can ask the right questions, and conduct, manage, apply and disseminate research for practice and policy. This Review describes some of the evolving issues, knowledge and programmes focused on building research capacity in low- and middle-income countries in general and for brain and nervous system disorders in particular.

Identification and functional characterization of rare SHANK2 variants in schizophrenia. Mol Psychiatry 2015; 20:1489-98.

Abstract
Recent genetic data on schizophrenia (SCZ) have suggested that proteins of the postsynaptic density of excitatory synapses have a role in its etiology. Mutations in the three SHANK genes encoding for postsynaptic scaffolding proteins have been shown to represent risk factors for autism spectrum disorders and other neurodevelopmental disorders. To address if SHANK2 variants are associated with SCZ, we sequenced SHANK2 in 481 patients and 659 unaffected individuals. We identified a significant increase in the number of rare (minor allele frequency<1%) SHANK2 missense variants in SCZ individuals (6.9%) compared with controls (3.9%, P=0.039). Four out of fifteen non-synonymous variants identified in the SCZ cohort (S610Y, R958S, P1119T and A1731S) were selected for functional analysis. Overexpression and knockdown-rescue experiments were carried out in cultured primary hippocampal neurons with a major focus on the analysis of morphological changes. Furthermore, the effect on actin polymerization in fibroblast cell lines was investigated. All four variants revealed functional impairment to various degrees, as a consequence of alterations in spine volume and clustering at synapses and an overall loss of presynaptic contacts. The A1731S variant was identified in four unrelated SCZ patients (0.83%) but not in any of the sequenced controls and public databases (P=4.6 × 10(-5)). Patients with the A1731S variant share an early prodromal phase with an insidious onset of psychiatric symptoms. A1731S overexpression strongly decreased the SHANK2-Bassoon-positive synapse number and diminished the F/G-actin ratio. Our results strongly suggest a causative role of rare SHANK2 variants in SCZ and underline the contribution of SHANK2 gene mutations in a variety of neuropsychiatric disorders.

Abstract
Risk of developing emotional and behavioral mental health problems increases markedly during adolescence. Despite this increasing need, most adolescents, particularly ethnic minority youth, do not seek professional help. Informed by conceptual models of health behavior, the current study examined how cultural values are related to help seeking among adolescents from 2 distinct racial/ethnic groups. Using a prospective survey design, 169 Vietnamese American and European American youth in 10th and 11th grade reported on their mental health need, as measured by emotional/behavioral mental health symptoms and stressful life events, with participants reporting on their help-seeking behavior at 6-month follow-up assessments. Multinomial logistic regression analyses indicated that mental health need interacted with cultural values and ethnicity to predict help-seeking behavior. Specifically, associations between symptoms and stressful life events, and help-seeking behavior were smaller among Vietnamese American adolescents, and among adolescents with strong family obligation values. These results underscore the complex sociocultural factors influencing adolescents' help-seeking behavior, which have important implications for engaging youth in needed mental health care.

Abstract
BACKGROUND Low drug levels are associated with emerging loss of response to anti-TNF. However, this may not be the case in patients with long-term remission. AIM To investigate the outcome of anti-TNF discontinuation in patients with long-term remission and incidental undetectable drug levels. METHODS A retrospective cohort study examining the duration of relapse-free survival in IBD patients in remission who discontinued infliximab or adalimumab having undetectable drug levels. RESULTS Forty eight patients who discontinued anti-TNF while in remission and had available drug levels were identified in two centres in France and Israel (infliximab-treated 35, adalimumab-13, Crohn's disease 30, ulcerative colitis 18, mean treatment duration of 22.7 ± 12.4 months). Endoscopy/MRE before stopping showed absence of active inflammation in 40/42 (95%) of evaluated patients, while inflammatory biomarkers (CRP and/or Calprotectin) were completely normal in only 31/48 (65%) of patients. During 12 months median follow-up, relapse occurred in 16/20 (80%) of patients who stopped anti-TNF while having measurable drug levels compared with 9/28 (32%) of patients who had undetectable drug levels (OR: 8.4, 95% CI: 2.2-32, P = 0.002). Relapse-free survival after anti-TNF cessation was significantly longer in patients with absent drug compared to those with detectable drug (P < 0.001, log rank test). On multivariate analysis, a patient's decision to stop therapy was weakly associated and abnormal inflammatory biomarkers and detectable drug levels were both strongly and independently associated with a higher risk of relapse after drug discontinuation. CONCLUSION Incidental finding of undetectable anti-TNF drug levels in patients with stable long-term deep remission may identify a subset of patients whose clinical remission is no longer dependent on anti-TNF treatment.

Abstract
BACKGROUND In high income countries in Europe and North America, early identification and intervention for autism spectrum disorders (ASD) have been linked to improved long-term outcomes. However, in most low and middle income countries (LMIC) little is known about use or availability of such services, which limits the ability of policy and development planning. The purpose of the present study was assess the use of ASD services in Vietnam, an Asian LMIC, in order to identify areas within the field that should be specifically targeted to improve ASD services in Vietnam. METHODS Surveys were conducted in six different cities across Vietnam with 90 parents/caregivers of children with ASD, 115 professionals working with children with ASD, and 10 directors of agencies providing ASD services. Parents/caregivers' survey assessed demographics and information regarding their child's symptoms and services the child received. Professionals' survey assessed their demographic and professional background, the ASD services they provide, and their perspective on the quality of ASD services at their agency. Directors' survey included these same questions as well as additional questions regarding the operation of the agency. RESULTS Early identification and intervention ASD services are available in Vietnam, at least in major cities. However, there is a lack of well-trained professionals, the tools used for evaluation and diagnosis are limited, outdated and unstandardized, and the quality of services is questionable. Most importantly, a scientific evidence base for services is absent, and the country lacks an official governmental policy for supporting children with ASD. CONCLUSIONS Research directly assessing the quality of ASD services in Vietnam is needed. Most centrally, efforts at facilitating governmental policy and support advocacy are needed to increase the likelihood that families and children with ASD will receive appropriate and effective services.

Abstract
We analysed the germination of seeds after their passage through the digestive tract of small floodplain fishes. Samples were collected in five open flooded fields of the northern Pantanal in March 2011. All fishes were sacrificed and their intestinal contents were removed. The fecal material was weighed and stored at 4°C in a GF/C filter wrapped in aluminum foil. The material was then transferred to a receptacle containing sterilised soil from the sampling area. The fecal samples were kept in a germination chamber for 68 days and then transferred to a greenhouse for another 67 days. We collected a total of 45 fish species and 1014 individuals which produced a total amount of 32 g of fresh fecal mass and 11 seedlings. We were able to identify six seedlings: two Banara arguta, two Steinchisma laxa, one Hymenachne amplexicaulis and one Luziola sp.. The fish species that produced samples with seedlings were Astyanax assuncionensis, Metynnis mola, Plesiolebias glaucopterus, Acestrorhyncus pantaneiro and Anadoras wendelli. With the exception of B. arguta the remaining plant species and all fish species were not known to be associated with the seed dispersal process of these plants. We found a ratio of 0.435 seedlings.g-1 of fresh fecal material, which is 100 times higher than the amount of seedlings encountered in fresh soil mass (92,974 grams) in seed bank studies conducted in the same study area. In particular, Astyanax assuncionensis and Metynnis mola were among the most frequent and most abundant fish taxa in the area. Together with the high seed concentration in the fish fecal material, this evidence allows us to conclude that such fish species may play an important role in seed dispersal in the herbaceous plants of the Pantanal.

Abstract
The present study identified moderators of Multisystemic Therapy's (MST) effects on adolescent conduct problems, considering facilitation and proximal process moderation models. The sample included 164 adolescents (mean age = 14.6 years; 83% male) randomly assigned to receive MST or services as usual; parent, youth, and teacher reports of adolescent functioning were obtained. A number of significant moderators were identified. Proximal process moderation patterns were identified (e.g., families with parents with lower levels of adaptive child discipline skills gained more from MST), but the majority of significant interactions showed a facilitation moderation pattern with, for instance, higher levels of adaptive functioning in families and parents appearing to facilitate MST (i.e., greater benefits from MST were found for these families). This facilitation pattern may reflect such families being more capable of and/or more motivated to use the resources provided by MST. It is suggested that factors consistently identified as facilitation moderators may serve as useful foci for MST's strength-based levers of change approach. Other implications of these findings for individualized treatment also are discussed.

Abstract
Children and adolescents with Crohn's disease (CD) present often with a more complicated disease course compared to adult patients. In addition, the potential impact of CD on growth, pubertal and emotional development of patients underlines the need for a specific management strategy of pediatric-onset CD. To develop the first evidenced based and consensus driven guidelines for pediatric-onset CD an expert panel of 33 IBD specialists was formed after an open call within the European Crohn's and Colitis Organisation and the European Society of Pediatric Gastroenterolog, Hepatology and Nutrition. The aim was to base on a thorough review of existing evidence a state of the art guidance on the medical treatment and long term management of children and adolescents with CD, with individualized treatment algorithms based on a benefit-risk analysis according to different clinical scenarios. In children and adolescents who did not have finished their growth, exclusive enteral nutrition (EEN) is the induction therapy of first choice due to its excellent safety profile, preferable over corticosteroids, which are equipotential to induce remission. The majority of patients with pediatric-onset CD require immunomodulator based maintenance therapy. The experts discuss several factors potentially predictive for poor disease outcome (such as severe perianal fistulizing disease, severe stricturing/penetrating disease, severe growth retardation, panenteric disease, persistent severe disease despite adequate induction therapy), which may incite to an anti-TNF-based top down approach. These guidelines are intended to give practical (whenever possible evidence-based) answers to (pediatric) gastroenterologists who take care of children and adolescents with CD; they are not meant to be a rule or legal standard, since many different clinical scenario exist requiring treatment strategies not covered by or different from these guidelines.

Abstract
As part of the global mental health movement's focus on identifying and reducing international disparities, this study conducted the first nationally representative child mental health epidemiological survey in Vietnam. We assessed as risk/protective factors several family social structure characteristics (e.g., presence of grandparents, number of siblings in the home) of particular relevance to non-Western countries. Epidemiological data using the Child Behavior Checklist and the Strengths and Difficulties Questionnaire were collected at 60 sites in 10 of Vietnam's 63 provinces selected to provide a nationally representative sample, which included 1,314 adult informants of children 6-16 years of age, and 591 children aged 12-16. Vietnamese children's mental health functioning was reported overall to be better by approximately a third standard deviation than the international average; this international difference was particularly large for externalizing (behavior) problems as compared to internalizing (emotional) problems, suggesting that a cultural problem suppression model may be operating in Vietnam. Significant variability in mental health problems was found across provinces, emphasizing the need for nationally representative samples when conducting child mental health epidemiological surveys. Contrary to many other studies, in Vietnam higher SES was found to be a risk factor for attention/hyperactivity problems.

Abstract
BACKGROUND Methionine adenosyltransferase I/III (MATI/III) deficiency is the most common genetic cause of persistent isolated hypermethioninemia. Patients and Methods : This is a retrospective data analysis of 62 newborns with elevated methionine detected by newborn screening between January 2000 and June 2013. The clinical, biochemical, and molecular findings of a subset of these children with MAT1A mutations associated with MATI/III deficiency are presented. RESULTS Of the 62 newborns with elevated methionine, 12 were identified as having classical homocystinuria; 37 were false-positives; and 13 were found to have isolated persistent hypermethioninemia in the absence of biochemical markers of homocystinuria, abnormal liver function studies, or other causes of elevated methionine. These 13 individuals underwent genetic testing for changes in the MAT1A gene, associated with MATI/III deficiency. Three of 13 were found to have the common autosomal dominant R264H mutation, one was found to be a compound heterozygote for two novel pathogenic mutations, and three were found to be heterozygotes for previously reported mutations shown to cause autosomal recessive MATI/III deficiency when present in homozygous or a compound heterozygous configuration. The remaining six patients had variants of unknown clinical significance or novel mutations. For the majority of individuals, methionine persisted above the normal range but trended downward over time. None of these 13 individuals was started on a low-methionine diet, and all have age-appropriate growth and development. CONCLUSION These cases show that individuals with even single changes in the MAT1A gene may have elevations in methionine identified by newborn screening, which may persist for months after birth without any clinical consequences.

Abstract
In this article, we discuss the Vietnam Multicomponent Collaborative Care for Depression Program, which was designed to provide evidence-based depression care services in low-resource, non-Western settings such as Vietnam. The article provides the program development background; the social, economic, and political context in which the program was developed; and the structure and content of the program and their underlying rationale in the context of rural Vietnam. Although the program was found to be acceptable, feasible, and effective in reducing depression outcomes, we did face challenges in implementation, which are outlined in this article. Key challenges included cultural factors (e.g., a lack of recognition of depression as a health-related entity amenable to professional treatment, relatively low levels of psychological mindedness useful for understanding of psychological interventions) and health system (e.g., lack of mental health specialists, overburdened health providers unfamiliar with behavioral interventions) factors. We discuss the strategies we employed to resolve these challenges and our successes and failures therein. We conclude with recommendations for others interested in implementing similar programs in low- and middle-income countries settings.

Abstract
OBJECTIVE Adolescent conduct problems exact serious social as well as personal costs, and effective treatments are essential. One of the most widely disseminated and effective programs for the treatment of serious conduct problems in adolescents is Multisystemic Therapy (MST). However, most evaluations of MST have involved the developers of MST. The purpose of the present study was to conduct an independent evaluation of MST, with non-court-referred adolescents with conduct problems. METHOD Participants were 164 adolescents ages 11-18 years who were recruited from self-contained behavior intervention classrooms in public schools. Adolescents and their families were randomly assigned to receive MST or services as usual. Outcome measures assessed conduct problems, school functioning, and court records of criminal behavior. Participants were followed for 18 months after baseline using parent, adolescent, and teacher reports; arrest data were collected for 2.5 years postbaseline. RESULTS Two of 4 primary outcome measures focused on externalizing problems showed significant treatment effects favoring MST. Several secondary and intervention targets pertaining to family functioning and parent psychopathology showed positive effects of MST, and no negative effects were identified. CONCLUSIONS Results provide some further support for the effectiveness of MST, although smaller effect sizes than previous studies also suggest the complexity of successful dissemination, particularly to non-court-referred populations.

[PMID: 23770126 PMCID: PMC3795956 DOI: 10.1016/j.ntt.2013.06.003] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2013] [Revised: 06/06/2013] [Accepted: 06/08/2013] [Indexed: 10/26/2022]
Abstract
BACKGROUND Fish are important sources of protein and contain a variety of nutrients, such as n-3 long-chain polyunsaturated fatty acids (PUFA), essential for normal brain development. Nevertheless, all fish also contain methyl mercury (MeHg), a known neurotoxicant in adequate dosage. Our studies of the Seychelles Child Development Study (SCDS) Main Cohort enrolled in 1989-1990 (n=779) have found no consistent pattern of adverse MeHg effects at exposures achieved by daily fish consumption. Rather, we have observed evidence of improved performance on some cognitive endpoints as prenatal MeHg exposure increases in the range studied. These observations cannot be related to MeHg and may reflect the role of unmeasured covariates such as essential nutrients present in fish. To determine if these associations persist into young adulthood, we examined the relationship between prenatal MeHg exposure, recent PUFA exposure and subjects' neurodevelopment and behavior at 19 years of age. METHODS We examined 533 participants using the following test battery: the Profile of Mood States-Bipolar (POMS-Bi); Finger Tapping; Kaufman Brief Intelligence Test (K-BIT); measures of Fine Motor Control and Complex Perceptual Motor Control; and Visual Spatial Contrast Sensitivity. We collected the following covariates: maternal IQ, family life course stressors, socioeconomic status, and subjects' recent postnatal MeHg, sex, and computer use. Primary analyses (based on N=392-475) examined covariate-adjusted associations in multiple linear regression models with prenatal MeHg as the primary exposure measure. Secondary analyses additionally adjusted for total n-6 and fish-related n-3 PUFA measured in the subjects' serum at the 19-year examination. RESULTS Study participants had a mean prenatal MeHg exposure of 6.9 ppm, and a mean recent postnatal exposure of 10.3 ppm. There were no adverse associations between prenatal MeHg and any of the measured endpoints. For recent postnatal MeHg exposure, however, adverse associations were observed for Finger Tapping (non-dominant hand) among women and for the K-BIT Matrices for both sexes, with or without adjustment for PUFA. CONCLUSION Our findings continue to provide no evidence for an adverse effect of prenatal MeHg exposure on development in a cohort that consumes fish daily. Observations for postnatal MeHg exposure will need to be confirmed using more comprehensive exposure measures.

Abstract
We present here the first genome-wide characterization of linkage disequilibrium (LD) in the French Blonde d'Aquitaine (BLA) breed, a well-muscled breed renowned for producing high-yielding beef carcasses. To assess the pattern and extent of LD, we used a sample of 30 unrelated bulls and 36 923 single nucleotide polymorphisms (SNPs) covering all cattle autosomes. The squared correlation of the alleles at two loci (r(2) ) was used as a measure of LD. The analysis of adjacent marker pairs revealed that the level of LD decreases rapidly with physical distance between SNPs. Overall mean r(2) was 0.205 (±0.262). Strong LD (r(2) > 0.8) and useful LD (measured as r(2 ) > 0.2) were observed within genomic regions of up to 720 and 724 kb, respectively. We analysed the genetic structure of the BLA population and found stratification. The observed genetic sub-structuring is consistent with the known recent demographic history that occurred during BLA breed formation. Our results indicate that LD mapping of phenotypic traits in the BLA population is feasible; however, because of this sub-structuring, special care is needed to reduce the likelihood of false-positive associations between marker loci and traits of interest.

Abstract
Intimate partner violence (IPV) against women occurs in all countries, with wide-ranging negative effects, including on mental health. IPV rates vary widely across countries, however, suggesting cultural factors may play a role in IPV. The primary purpose of the present study was to assess relations among IPV, mental health symptoms, and cultural beliefs among Vietnamese women, focusing on moderator effects of cultural beliefs on relations between IPV and mental health. IPV, anxious and depressive mental health symptoms, and culturally-related beliefs about IPV were cross-sectionally assessed in 105 married adult Vietnamese women randomly selected from public population registries in five provinces. IPV was significantly correlated with anxiety, depression, and suicidal ideation. Relations were moderated by wives' culturally-related beliefs about abuse (e.g., relations between IPV and mental health symptoms were smaller for women who believed that nothing could be done about abuse). Findings suggest that when attempting to prevent or treat effects of IPV, it will be important to consider that certain beliefs about IPV generally viewed as maladaptive (e.g., nothing can be done about abuse) may have adaptive effects, at least in the short-term, on relations between IPV and mental health functioning.

Abstract
Gemcitabine (dFdC) is a novel pyrimidine antimetabolite with documented antineoplastic activity against metastatic non-small cell lung cancer (NSCL), pancreatic carcinoma, ovarian and breast cancer. The side effects of gemcitabine are generally mild; severe infections are reported in less than Ilo of patients. In contrast, other new nucleoside analogues such as the purine antimetabolite fludarabine lead to a significant alteration of the CD4/CD8 lymphocyte ratio associated with an increased risk for opportunistic infections. This study investigates the effect of gemcitabine on different lymphocyte subsets during consecutive applications. 16 patients with solid rumours (3 non-small cell lung cancer, 3 pancreas, 3 testicular, 2 breast, ovarian germ-cell, 1 ovarian, 1 small cell lung, 1 gastric cancer, 1 carcinoma of unknown primary); 15 patients were previously treated, received at least 3 applications of gemcitabine (1,000 mg/m(2) as a 30 min infusion, at days 1, 8, 15; q 4 weeks). Lymphocytes surface antigens were analysed by standard technique flow cytometry prior to every infusion. The median number of leukocytes before therapy was 7823/mu l, with lymphocytes 875/mu l, including 68% T-cells (CD3(+)), 9% B-cells (CD19(+); CD20(+)) and 15% NK-cells (CD56(+); CD16(+); CD3(-)), the CD4/CD8 ratio was 1.7. After gemcitabine therapy the median number of leukocytes was 5136/mu l, with lymphocytes 1012/mu l, including 77% T-cells, 8% B-cells and 10% NK-cells and a CD4/CD8 ratio of 2.2. Severe complications or opportunistic infections were not seen in these 16 patients. No significant change of CD4/CD8 ratios and NK-ccll numbers was seen in our patients with solid tumours during weekly treatment with gemcitabine. A severely increased risk for opportunistic infections following treatment with the new antimetabolite gemcitabine appears unlikely.

Abstract
A 2-wave longitudinal study of young adolescents was used to test whether peer victimization predicts depressive symptoms, depressive symptoms predict peer victimization, or the 2 constructs show reciprocal relations. Participants were 598 youths in Grades 3 through 6, ages 8 to 14 (M = 10.9, SD = 1.2) at Wave 1. The sample was 50.7% female and 90.3% Caucasian. Participants completed self-reports of depressive symptoms, and self-reports and peer nomination measures of physical and relational peer victimization at 2 time points separated by 1 year. The results were as follows: (a) depressive symptoms predicted change in both physical and relational victimization, but neither type of peer victimization predicted change in depressive symptoms; (b) depressive symptoms were more predictive of physical victimization for boys than for girls; and (c) boys experienced more physical victimization, and girls experienced more relational victimization. Expression of some depressive symptoms may represent signs of vulnerability. For boys, they may also represent a violation of gender stereotypes. Both factors could be responsible for these effects. Implications for intervention include the possibility that treatment of depression in young adolescents may reduce the likelihood of peer victimization.

Abstract
Children and adolescents are among the highest need populations in regards to mental health support, especially in low and middle income countries (LMIC). Yet resources in LMIC for prevention and treatment of mental health problems are limited, in particular for children and adolescents. In this paper, we discuss a model for development of child and adolescent mental health (CAMH) resources in LMIC that has guided a ten year initiative focused on development of CAMH treatment and research infrastructure in Vietnam. We first review the need for development of mental health resources for children and adolescents in general, and then in Vietnam. We next present the model that guided our program as it developed, focused on the twin Capacity Development Goals of efficacy and sustainability, and the Capacity Development Targets used to move towards these goals. Finally we discuss our CAMH development initiative in Vietnam, the center of which has been development of a graduate program in clinical psychology at Vietnam National University, linking program activities to this model.

Abstract
Intelligence testing is used for many purposes including identification of children for proper educational placement (e.g., children with learning disabilities, or intellectually gifted students), and to guide education by identifying cognitive strengths and weaknesses so that teachers can adapt their instructional style to students' specific learning styles. Most of the research involving intelligence tests has been conducted in highly developed Western countries, yet the need for intelligence testing is as or even more important in developing countries. The present study, conducted through the Vietnam National University Clinical Psychology CRISP Center, focused on the cultural adaptation of the WISC-IV intelligence test for Vietnam. We report on (a) the adaptation process including the translation, cultural analysis and modifications involved in adaptation, (b) present results of two pilot studies, and (c) describe collection of the standardization sample and results of analyses with the standardization sample, with the goal of sharing our experience with other researchers who may be involved in or interested in adapting or developing IQ tests for non-Western, non-English speaking cultures.

Abstract
Xanthomonas axonopodis pv. passiflorae causes bacterial spot in passion fruit. It attacks the purple and yellow passion fruit as well as the sweet passion fruit. The diversity of 87 isolates of pv. passiflorae collected from across 22 fruit orchards in Brazil was evaluated using molecular profiles and statistical procedures, including an unweighted pair-group method with arithmetical averages-based dendrogram, analysis of molecular variance (AMOVA), and an assigning test that provides information on genetic structure at the population level. Isolates from another eight pathovars were included in the molecular analyses and all were shown to have a distinct repetitive sequence-based polymerase chain reaction profile. Amplified fragment length polymorphism technique revealed considerable diversity among isolates of pv. passiflorae, and AMOVA showed that most of the variance (49.4%) was due to differences between localities. Cluster analysis revealed that most genotypic clusters were homogeneous and that variance was associated primarily with geographic origin. The disease adversely affects fruit production and may kill infected plants. A method for rapid diagnosis of the pathogen, even before the disease symptoms become evident, has value for producers. Here, a set of primers (Xapas) was designed by exploiting a single-nucleotide polymorphism between the sequences of the intergenic 16S-23S rRNA spacer region of the pathovars. Xapas was shown to effectively detect all pv. passiflorae isolates and is recommended for disease diagnosis in passion fruit orchards.

Abstract
In this paper, we discuss development of the Vietnam National University graduate Clinical Psychology Program, which has the goal of training both Vietnamese researchers who will develop and evaluate culturally appropriate mental health treatments, as well as Vietnamese clinicians who will implement and help disseminate these evidence-based treatments. We first review the background situation in Vietnam regarding mental health, and its infrastructure and training needs, and discuss the process through which the decision was made to develop a graduate program in clinical psychology as the best approach to address these needs. We then review the development process for the program and its current status, and our focus on the schools as a site for service provision and mental health task shifting. Finally, we outline future goals and plans for the program, and discuss the various challenges that the program has faced and our attempts to resolve them.

Abstract
BACKGROUND There are no current recommendations for bowel cleansing before colonoscopy in children. The Israeli Society of Pediatric Gastroenterology and Nutrition (ISPGAN) established an iterative working group to formulate evidence-based guidelines for bowel cleansing in children prior to colonoscopy. METHOD Data were collected by systematic review of the literature and via a national-based survey of all endoscopy units in Israel. Based on the strength of evidence, the Committee reached consensus on six recommended protocols in children. Guidelines were finalized after an open audit of ISPGAN members. RESULTS Data on 900 colonoscopies per year were accrued, which represents all annual pediatric colonoscopies performed in Israel. Based on the literature review, the national survey, and the open audit, several age-stratified pediatric cleansing protocols were proposed: two PEG-ELS protocols (polyethylene-glycol with electrolyte solution); Picolax-based protocol (sodium picosulphate with magnesium citrate); sodium phosphate protocol (only in children over the age of 12 years who are at low risk for renal damage); stimulant laxative-based protocol (e. g. bisacodyl); and a PEG 3350-based protocol. A population-based analysis estimated that the acute toxicity rate of oral sodium phosphate is at most 3/7320 colonoscopies (0.041 %). Recommendations on diet and enema use are provided in relation to each proposed protocol. CONCLUSION There is no ideal bowel cleansing regimen and, thus, various protocols are in use. We propose several evidence-based protocols to optimize bowel cleansing in children prior to colonoscopy and minimize adverse events.

Abstract
Therapist treatment adherence has received a great deal of attention in recent years, in part because of its relation to treatment outcomes. Although certain therapist behaviors have been found to be associated with treatment outcomes, little is known about client factors impacting on therapists' ability to adhere to treatment protocols. In this study, we evaluated effects of parental beliefs, psychopathology, and interaction styles on therapists' adherence to Multi-systemic Therapy (MST) principles. Eighty-two parents participating in a clinical trial of MST completed baseline measures assessing psychopathology, family functioning, and treatment expectations. Analyses indicated that parental perceptions of therapist adherence were established within the first 4 weeks of treatment, and that parental psychopathology, motivation, expectations, and child rearing practices were related to parental ratings of therapist adherence. Results were essentially unchanged when controlling for parental positive response style. Clinical and research implications of the findings are discussed.

Abstract
The fixed-interval schedule of reinforcement is one of the more widely studied schedules in the experimental analysis of behavior and is also a common baseline for behavior pharmacology. Despite many intensive studies, the controlling variables and the pattern of behavior engendered are not well understood. The present study examined the microstructure and superstructure of the behavior engendered by a fixed-interval 5- and a fixed-interval 15-minute schedule of food reinforcement in the pigeon. Analysis of performance typical of fixed-interval responding indicated that the scalloped pattern does not result from smooth acceleration in responding, but, rather, from renewed pausing early in the interval. Individual interresponse-time (IRT) analyses provided no evidence of acceleration. There was a strong indication of alternation in shorter-longer IRTs, but these shorter-longer IRTs did not occur at random, reflecting instead a sequential dependency in successive IRTs. Furthermore, early in the interval there was a high relative frequency of short IRTs. Such a pattern of early pauses and short IRTs does not suggest behavior typical of reinforced responding as exemplified by the pattern found near the end of the interval. Thus, behavior from clearly scalloped performance can be classified into three states: postreinforcement pause, interim behavior, and terminal behavior.

Abstract
PURPOSE Factors influencing response to medications in Crohn's disease (CD) patients are not fully understood. We aimed to evaluate the relationships between NOD2/CARD15 mutations, disease phenotype and age of CD diagnosis and response to medical treatment with systemic steroids, azathioprine (AZA) or 6-mercaptopurine (6-MP), and infliximab. METHODS A retrospective medical records analysis was made of patients previously tested for the CD-associated NOD2/CARD15 mutations. Harvey- Bradshaw score was used to assess remission or response to therapy. RESULTS CD-associated NOD2/CARD15 mutations were not related to the rate of steroids dependency or clinical response to AZA/6-MP and infliximab. Steroid dependency was associated with colonic involvement. Thirty-three of 127 (26%) patients with colonic disease were steroid dependent, compared with 7/72 (9.7%) patients with isolated small bowel disease (ISBD), (p = 0.009). ISBD was mildly associated with a better remission/response to AZA/6-MP treatment. Disease behavior and age of diagnosis were not related to response to therapy. CONCLUSIONS Response to treatment with systemic steroids, AZA/6-MP and infliximab are not related to NOD2/CARD15 mutations, age of diagnosis and disease behavior. Patients with colonic disease have higher rates of steroid dependency.

Abstract
Individuals react in a variety of ways when experiencing environmental challenges exceeding their capacity to cope adaptively. Some researchers have suggested that Asian populations tend to react to excessive stress with somatic symptoms, whereas Western populations tend to respond more with affective or depressive symptoms. Other researchers, however, have suggested that such differences may represent different approaches to help seeking rather than actual variations in prevalence. The present study compared somatic versus affective symptoms in U.S. and Thai children from community and mental health clinic samples. In the clinic-referred sample, Thai children were reported to have higher levels of somatic versus depressive symptoms relative to U.S. children, whereas in the community sample, both groups were reported to have slightly higher levels of depressive than somatic symptoms. Because a primary difference between clinic-referred and community samples is that the former have been through the clinical referral process (i.e., were seeking help), these results suggest that differences in somatic versus depressive symptom presentation may be related to help-seeking behavior, at least for the samples involved in this study.

Abstract
Foetal exposure to antiandrogens alters androgen-sensitive development in male rodents, resulting in less male-typical behaviour. Foetal phthalate exposure is also associated with male reproductive development in humans, but neurodevelopmental outcomes have seldom been examined in relation to phthalate exposure. To assess play behaviour in relation to phthalate metabolite concentration in prenatal urine samples, we recontacted participants in the Study for Future Families whose phthalate metabolites had been measured in mid-pregnancy urine samples. Mothers completed a questionnaire including the Pre-School Activities Inventory, a validated instrument used to assess sexually dimorphic play behaviour. We examined play behaviour scores (masculine, feminine and composite) in relationship to (log(10)) phthalate metabolite concentrations in mother's urine separately for boys (N = 74) and girls (N = 71). Covariates (child's age, mother's age and education and parental attitude towards atypical play choices) were controlled using multivariate regression models. Concentrations of dibutyl phthalate metabolites, mono-n-butyl phthalate (MnBP) and mono-isobutyl phthalate (MiBP) and their sum, were associated with a decreased (less masculine) composite score in boys (regression coefficients -4.53,-3.61 and -4.20, p = 0.01, 0.07 and 0.04 for MnBP, MiBP and their sum respectively). Concentrations of two urinary metabolites of di(2-ethylhexyl) phthalate (DEHP), mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP) and mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and the sum of these DEHP metabolites plus mono(2-ethylhexyl) phthalate were associated with a decreased masculine score (regression coefficients -3.29,-2.94 and -3.18, p = 0.02, 0.04 and 0.04) for MEHHP, MEOHP and the sum respectively. No strong associations were seen between behaviour and urinary concentrations of any other phthalate metabolites in boys, or between girls' scores and any metabolites. These data, although based on a small sample, suggest that prenatal exposure to antiandrogenic phthalates may be associated with less male-typical play behaviour in boys. Our findings suggest that these ubiquitous environmental chemicals have the potential to alter androgen-responsive brain development in humans.
