Unlabelled: Aim of this paper is to identify what is a difficult question, according to nurses' perceptions. Since the knowledge on this area is limited, a qualitative method was preferred for a pilot study.
Methods: As part of a training exercise, fifty-one nurses were requested to recall, from their own experience, and to describe, a difficult question asked by a patient, that created problems to the nurse. Data were analysed with hermeneutical-interpretative methodology.
Results: Three main conceptual cores were identified: the characteristics of the difficult question; the "after the question"; and the source of the problem experienced. The first core is related to the content of the question but also to the characteristics of the person that formulates it, to the setting, and to the subjective perception of the time window. What happens after the question is related to the nurse's reactions. The third conceptual core is related to the interplay between different possible roles: patient, professional, and human being. The denominator of the three cores has to do with the emotional-relational dimension of the communication. This difficulty may partly be due to the lack of education in the management of the emotions.

Background: In developed countries, most of the neurologists use pericranial nerve blocks to treat headache patients, nevertheless, the knowledge and use patterns of this technique in developing countries are unknown.
Objective: Evaluate the knowledge and use patterns of pericranial nerve blocks in headache treatment by Mexican neurologists.
Material And Methods: We did a cross-sectional study, 90 Mexican neurologists completed a 26-question survey including data about sociodemographics, knowledge and patterns of use of pericranial nerve blocks.

One of the most important and difficult challenges in the research of molecular evolution is modeling the process of amino acid substitutions. Although single-matrix models, such as the LG model, are popular, their capability to properly capture the heterogeneity of the substitution process across sites is still questioned. Several mixture models with multiple matrices have been introduced and shown to offer advantages over single-matrix models.

Background: Orthotopic murine models of pancreatic cancer represent an important tool for evaluating treatment strategies. Several genetically modified mouse tumors and xenograft models have been reported. Genetic models have unpredictable growth and variable waiting period, while orthotopic models are operative ones, difficult to create and result in irregular metastasis.

Community stakeholder participation can be incredibly valuable for the qualitative model development process. However, modelers often encounter challenges for participatory modeling projects focusing on high-complexity, synergistic interactions between multiple issues, systems, and granularity. The diverse stakeholder perspectives and volumes of information necessary for developing such models can yield qualitative models that are difficult to translate into quantitative simulation or clear insight for informed decision-making.

Primary pharmacologic interventions include stimulants and non-stimulants. Diagnosing ADHD is typically more difficult in women due to a range of different symptoms between the sexes.
