Introduction Although the development of nursing research is every day becoming more concrete, the related Mexican journals do not fulfill the index level of methodological rigor required by the National System of Researchers. Objective To describe the topics and methodological characteristics of nursing publications in the main Mexican journals in the last 5 years. Method This is a descriptive, retrospective, and transversal study. Six national journals published from the 2nd semester of 2010 to the 2nd semester of 2015 were analyzed. The sample included 244 original and/or research articles. Descriptive statistics, including frequencies and percentages, were calculated. Results Education level of the 1st author: master's degree or superior: 38.2%; institutions of higher studies: 66.8%; main topic: clinical 45.8%; does not use theory: 84.0%. From the studies with a quantitative design: descriptive analysis: 49.1%; transversal: 73.5%; without ethics registry: 79.6%. From the studies with qualitative design: semi-structured interview: 83.9%; open coding: 80.6%; rapport: 3.2%. Conclusions Future nursing research should implement and fulfill the corresponding criteria to enhance its quality, so that its products can become part of a trustable, replication-capable, and useful body of evidence which can drive the development of nursing.

Attention deficit hyperactivity disorder: From parents to children. / Trastorno por déficit de atención e hiperactividad: de padres a hijos.

INTRODUCTION: Multiple studies of attention deficit hyperactivity disorder (ADHD) have recognised a heritability factor in that a higher frequency of the disorder is observed in children with an affected relative. Our aim was to determine the association between ADHD symptoms in young children enrolled in five schools in Bogota and a history of ADHD symptoms in their parents using the Wender-Utah Rating Scale. METHODOLOGY: Case-control study of participants selected according to DSM-IV criteria for ADHD and the Behavioral Assessment System for Children (BASC) completed by parents and teachers; the WISC-IV scale was used to exclude children with cognitive deficit. Parents completed the Wender-Utah Rating Scale to retrospectively identify any ADHD symptoms in childhood. A score of 36 was used as a cutoff point. RESULTS: The study included 202 children: 117 cases and 85 controls. A positive history of ADHD symptoms in childhood was identified for 16% of 175 mothers and 20.6% of 141 fathers. The presence of symptoms in either parent, especially the mother, constitutes a significant risk factor for ADHD in children and this relationship persists after controlling for different variables. If both parents have the disorder, the risk tends to increase. CONCLUSION: Although ADHD has been linked to a genetic component, other environmental factors may be involved in the disorder.

Stability, structural, and magnetic phase diagrams of ternary ferromagnetic 3d-transition-metal clusters with five and six atoms.

We report a theoretical investigation of free-standing Fe(x)Co(y)Ni(z) ternary clusters with x + y + z = 5 and 6. Our study is performed within density functional theory as implemented in the GAUSSIAN 03 set of programs and with the BPW91/SDD level of theory. We analyze the geometries, chemical order, local and total magnetic moments, binding energies, excess energies, and second difference in the energy in the whole range of composition, from which structural, magnetic, and stability phase diagrams are predicted for these cluster sizes. We determine the optimal stoichiometries for these clusters as regards the maximum total magnetic moment and stability.
