Further evidence of the role of microRNA in schizophrenia: a case report.

According to the neurodevelopmental hypothesis of schizophrenia, genetic predisposing factors cause abnormalities in neural functions, leading to the disease. A 2-year follow-up of a young woman with schizophrenia is presented. Karyotype, Affymetrix CytoScan TM 750K SNP array, and optical genome mapping ultra-high molecular weight were carried out.

Changes in genetic and environmental influences on disordered eating between pre-menarche and postmenarche girls. A twin study.

significantly increase during puberty. The goal of this research is to evaluate changes during puberty which could have genetic and environmental influences on a broad spectrum of disordered eating attitudes and behaviors. Methods.

Hypoesthesia in generalised anxiety disorder and major depression disorder.

The determination of soft signs can be a conducive practice to understand the differential etiology between depression and anxiety. This study aims at examining malleolar hypoesthesia role in distinguishing between patients with generalised anxiety disorder (GAD) and major depression disorder (MDD). This study examines the presence of malleolar hypoesthesia in patients with GAD ( = 47) compared to patients with MDD ( = 48) and healthy individuals (controls;  = 99).

Psychiatric symptoms after temporal epilepsy surgery. A one-year follow-up study.

Psychiatric symptoms must be considered in patients with refractory temporal lobe epilepsy after epilepsy surgery. The main objectives of our study were to describe clinical and socio-demographical characteristics of a cohort of patients with pharmacoresistant temporal lobe epilepsy who underwent temporal lobe epilepsy surgery, and moreover, to evaluate possible risk factors for developing psychiatric symptoms. In order to achieve those goals, we conducted a prospective evaluation of psychopathology throughout the first year after surgery in a clinical sample of 72 patients, by means of three clinical rated measures; the Hamilton Anxiety Rating Scale (HARS), the Hamilton Depression Rating Scale (HDRS), and the Brief Psychiatric Rating Scale (BPRS).

Genetic and environmental contributions to perfectionism and its common factors.

Unlabelled: The aims of this study: (1) To evaluate the relative contributions of genetics and environment to perfectionism and it's two constructs: self-oriented, and socially prescribed perfectionism. (2) To clarify genetic and environmental common origins of both personal and social components.

Methods: Participants were 258 pairs of adolescent Spanish twins.

Genetic and environmental influences on psychological traits and eating attitudes in a sample of Spanish schoolchildren.

Introduction: The heritability of eating disorders has been estimated to range from 22% to over 62%.The aim of this study is to determine the relative influence of genetics and environment that contribute to the drive for thinness, body dissatisfaction, perfectionism, and ineffectiveness, by evaluating sex differences in a sample of adolescent twins from Valencia, Spain.

Material And Methods: Five hundred eighty-four pairs of adolescent twins between 13 and 18 years of age completed the study.

[Genetic and environmental contributions to body mass index in a Spanish adolescent twin sample].

Background And Objective: Twin and family studies support large genetic influences on variability in body mass index (BMI), with heritability estimates ranging from 47% to over 90%. Our objective was to study the relative contributions of genetics and environment to BMI, evaluating sex differences, in an adolescent twin sample from Valencia, Spain.

Material And Methods: Five hundred eighty-four pairs of adolescent twins between 13 and 18 years of age completed the study (82 monozygotic [MZ] and 87 dizygotic [DZ] pairs of male twins, 118 MZ and 102 DZ pairs of female twins, and 195 opposite-sex pairs of DZ twins).
