Pedigree-Based Description of Danubia Alba Rabbit Breed Lines.

The diversity of livestock animal breeds is an integral part of global biodiversity and requires careful management for sustainability and future availability. Avoiding inbreeding is a crucial aspect of mating of breeding animals. Our aims were to describe the quality of the pedigree, generation interval, gene origin, inbreeding, and effective population size of Danubia Alba rabbit lines.

Stability yield indices on different sweet corn hybrids based on AMMI analysis.

Currently, sweet corn is considered an important crop due to its high sugar content and low starch content. Important sugars in sweet corn include sucrose, fructose, glucose, and maltose. The purpose of the present study was to use the yield indices of the eight examined sweet corn hybrids and the correlation of the yield indices together.

Quantitative and qualitative yield in sweet maize hybrids.

Today, sweet corn is considered an important vegetable due to its high sugar content and low starch content. Cluster analysis and variance analysis showed that hybrids had variations in yield indices. GB, DE and GS hybrids had similar performance on indices.

Complex Congenital Heart Malformation Including Transposition of the Great Vessels, Presenting as Sudden Unexplained Infant Death.

Transposition of the great vessels (TGV) is a common congenital heart defect that is difficult to diagnose before birth. Antenatal diagnosis is associated with increased survival. Unusual features such as anomalous pulmonary artery origin may delay cyanosis, decreasing clinical suspicion.

Can Emotional and Behavioral Dysregulation in Youth Be Decoded from Functional Neuroimaging?

Introduction: High comorbidity among pediatric disorders characterized by behavioral and emotional dysregulation poses problems for diagnosis and treatment, and suggests that these disorders may be better conceptualized as dimensions of abnormal behaviors. Furthermore, identifying neuroimaging biomarkers related to dimensional measures of behavior may provide targets to guide individualized treatment. We aimed to use functional neuroimaging and pattern regression techniques to determine whether patterns of brain activity could accurately decode individual-level severity on a dimensional scale measuring behavioural and emotional dysregulation at two different time points.

White matter structure in youth with behavioral and emotional dysregulation disorders: a probabilistic tractographic study.

Importance: Psychiatric disorders in youth characterized by behavioral and emotional dysregulation are often comorbid and difficult to distinguish. An alternative approach to conceptualizing these disorders is to move toward a diagnostic system based on underlying pathophysiologic processes that may cut across conventionally defined diagnoses. Neuroimaging techniques have potentials for the identification of these processes.

Decreased amygdala-insula resting state connectivity in behaviorally and emotionally dysregulated youth.

The Research Domain Criteria (RDoC) adopts a dimensional approach for examining pathophysiological processes underlying categorically defined psychiatric diagnoses. We used this framework to examine relationships among symptom dimensions, diagnostic categories, and resting state connectivity in behaviorally and emotionally dysregulated youth selected from the Longitudinal Assessment of Manic Symptoms study (n=42) and healthy control youth (n=18). Region of interest analyses examined relationships among resting state connectivity, symptom dimensions (behavioral and emotional dysregulation measured with the Parent General Behavior Inventory-10 Item Mania Scale [PGBI-10M]; dimensional severity measures of mania, depression, anxiety), and diagnostic categories (Bipolar Spectrum Disorders, Attention Deficit Hyperactivity Disorder, Anxiety Disorders, and Disruptive Behavior Disorders).

Improving Clinical Prediction of Bipolar Spectrum Disorders in Youth.

This report evaluates whether classification tree algorithms (CTA) may improve the identification of individuals at risk for bipolar spectrum disorders (BPSD). Analyses used the Longitudinal Assessment of Manic Symptoms (LAMS) cohort (629 youth, 148 with BPSD and 481 without BPSD). Parent ratings of mania symptoms, stressful life events, parenting stress, and parental history of mania were included as risk factors.

Use of outpatient mental health services among children of different ages: are younger children more seriously ill?

Objective: The study compared use of specialty outpatient mental services among children ages six and seven and children ages eight through 12 and investigated predictors of differences in the patterns of service use by age.

Methods: Eligible children were first-time patients of clinics participating in the Longitudinal Assessment of Manic Symptoms who were between ages six and 12 and who were English speaking. Children who screened positive for symptoms of mania (N=1,124) were invited to participate, and families of 621 (55%) children consented.

Clinical decision making about child and adolescent anxiety disorders using the Achenbach system of empirically based assessment.

Anxiety disorders are common among children but can be difficult to diagnose. An actuarial approach to the diagnosis of anxiety may improve the efficiency and accuracy of the process. The objectives of this study were to determine the clinical utility of the Achenbach Child Behavior Checklist (CBCL) and Youth Self Report (YSR), two widely used assessment tools, for diagnosing anxiety disorders in youth and to aid clinicians in incorporating scale scores into an actuarial approach to diagnosis through a clinical vignette.

Behavioral and emotional dysregulation trajectories marked by prefrontal-amygdala function in symptomatic youth.

Background: Neuroimaging measures of behavioral and emotional dysregulation can yield biomarkers denoting developmental trajectories of psychiatric pathology in youth. We aimed to identify functional abnormalities in emotion regulation (ER) neural circuitry associated with different behavioral and emotional dysregulation trajectories using latent class growth analysis (LCGA) and neuroimaging.

Method: A total of 61 youth (9-17 years) from the Longitudinal Assessment of Manic Symptoms study, and 24 healthy control youth, completed an emotional face n-back ER task during scanning.

Emotional face processing in pediatric bipolar disorder: evidence for functional impairments in the fusiform gyrus.

Objective: Pediatric bipolar disorder involves poor social functioning, but the neural mechanisms underlying these deficits are not well understood. Previous neuroimaging studies have found deficits in emotional face processing localized to emotional brain regions. However, few studies have examined dysfunction in other regions of the face processing circuit.

Parsing dimensional vs diagnostic category-related patterns of reward circuitry function in behaviorally and emotionally dysregulated youth in the Longitudinal Assessment of Manic Symptoms study.

Importance: Pediatric disorders characterized by behavioral and emotional dysregulation pose diagnostic and treatment challenges because of high comorbidity, suggesting that they may be better conceptualized dimensionally rather than categorically. Identifying neuroimaging measures associated with behavioral and emotional dysregulation in youth may inform understanding of underlying dimensional vs disorder-specific pathophysiologic features.

Objective: To identify, in a large cohort of behaviorally and emotionally dysregulated youth, neuroimaging measures that (1) are associated with behavioral and emotional dysregulation pathologic dimensions (behavioral and emotional dysregulation measured with the Parent General Behavior Inventory 10-Item Mania Scale [PGBI-10M], mania, depression, and anxiety) or (2) differentiate diagnostic categories (bipolar spectrum disorders, attention-deficit/hyperactivity disorder, anxiety, and disruptive behavior disorders).

Prescription of psychiatric medications and polypharmacy in the LAMS cohort.

Objective: This study evaluated demographic and clinical correlates and predictors of polypharmacy at baseline assessment in the Longitudinal Assessment of Manic Symptoms (LAMS) sample, a cohort of children age six to 12 years at their first outpatient mental health visit at university-affiliated clinics.

Methods: Use of medications in four classes (mood stabilizers, antidepressants, antipsychotics, and stimulants) was assessed, and the Service Assessment for Children and Adolescents classified lifetime and current use of various services. Analyses examined correlates of the number of medications prescribed and odds of polypharmacy, defined as use of two or more concurrent medications.

The 24-month course of manic symptoms in children.

Objectives: The Longitudinal Assessment of Manic Symptoms (LAMS) study was designed to investigate phenomenology and establish predictors of functional outcomes in children with elevated manic symptoms. The purpose of this series of analyses was to determine whether the participants demonstrated different trajectories of parent-reported manic and biphasic symptoms over the first 24 months of follow-up and to describe the clinical characteristics of the trajectories.

Methods: The 707 participants were initially aged 6-12 years and ascertained from outpatient clinics associated with the four university-affiliated LAMS sites.

Phenomenology of bipolar disorder not otherwise specified in youth: a comparison of clinical characteristics across the spectrum of manic symptoms.

Objectives: Controversy surrounds the diagnostic categorization of children with episodic moods that cause impairment, but do not meet DSM-IV criteria for bipolar I (BD-I) or bipolar II (BD-II) disorder. This study aimed to characterize the degree to which these children, who meet criteria for bipolar disorder not otherwise specified (BD-NOS), are similar to those with full syndromal BD, versus those with no bipolar spectrum diagnosis (no BSD).

Methods: Children aged 6-12 years were recruited from nine outpatient clinics, preferentially selected for higher scores on a 10-item screen for manic symptoms.

Age differences in the phenomenology of pediatric bipolar disorder.

Background: The primary purpose of this study was to explore whether age differences in the phenomenology of bipolar disorders from 4 to 17 years of age exist.

Methods: Outcome measures included questionnaires pertaining to mood symptoms, psychosocial functioning, and family history of psychiatric illness. Phenomenology was examined in two diagnostic groups: syndromal bipolar disorder (bipolar I or II) and subsyndromal bipolar disorder (bipolar disorder not otherwise specified or cyclothymia) and across six age cohorts: 4-6, 7-8, 9-10, 11-13, and 14-17 years.

Examining the proposed disruptive mood dysregulation disorder diagnosis in children in the Longitudinal Assessment of Manic Symptoms study.

Objective: To examine the proposed disruptive mood dysregulation disorder (DMDD) diagnosis in a child psychiatric outpatient population. Evaluation of DMDD included 4 domains: clinical phenomenology, delimitation from other diagnoses, longitudinal stability, and association with parental psychiatric disorders.

Method: Data were obtained from 706 children aged 6-12 years who participated in the Longitudinal Assessment of Manic Symptoms (LAMS) study (sample was accrued from November 2005 to November 2008).

Examining the validity of cyclothymic disorder in a youth sample: replication and extension.

DSM-IV-TR defines four subtypes of bipolar disorder (BP): bipolar I, bipolar II, cyclothymic disorder and bipolar not otherwise specified (NOS). However, cyclothymic disorder in children is rarely researched, or often subsumed in an "NOS" category. The present study tests the replicability of findings from an earlier study, and expands on the criterion validity of cyclothymic disorder in youth.

What differentiates children visiting outpatient mental health services with bipolar spectrum disorder from children with other psychiatric diagnoses?

Objectives: To determine the contribution of parent-reported manic symptoms, family history, stressful life events, and family environment in predicting diagnosis of bipolar spectrum disorders (BPSD) in youth presenting to an outpatient psychiatric clinic.

Methods: A total of 707 6- to 12-year-old children [621 with elevated symptoms of mania (ESM+) based on screening via the Parent General Behavior Inventory 10-item Mania Scale (PGBI-10M) and 86 without ESM (ESM-)] received a comprehensive assessment.

Results: Of the 629 with complete data, 24% (n = 148) had BPSD.

Parents' perceptions of benefit of children's mental health treatment and continued use of services.

Objective: The authors examined the association of demographic and clinical characteristics, family history, and type of treatment among children receiving outpatient mental health services and parents' perception of treatment benefit. They also examined whether perceived benefit was related to continued use of services at six-month follow-up.

Methods: Parents of children age six to 12 years who were first-time patients at one of nine clinics participating in the Longitudinal Assessment of Manic Symptoms (LAMS) study completed the Parent General Behavior Inventory Ten-Item Mania Scale.

Pediatric bipolar disorder and ADHD: family history comparison in the LAMS clinical sample.

Background: Transgenerational association of bipolar spectrum disorder (BPSD) and attention deficit/hyperactivity disorder (ADHD) has been reported, but inconclusively.

Method: Children ages 6-12 were systematically recruited at first outpatient visit at 9 clinics at four universities and reliably diagnosed; 621 had elevated symptoms of mania (>12 on the Parent General Behavior Inventory 10-Item Mania Scale); 86 had scores below 12. We analyzed baseline data to test a familial association hypothesis: compared to children with neither BPSD nor ADHD, those with either BPSD or ADHD would have parents with higher rates of both bipolar and ADHD symptoms, and parents of comorbid children would have even higher rates of both.
