Introduction. Rhupus syndrome is the overlap of two autoimmune diseases, rheumatoid arthritis or juvenile idiopathic arthritis, and systemic lupus erythematosus, with a prevalence of 7-401 per 100,000 children. Felty's syndrome is characterized by the triad of juvenile idiopathic arthritis, splenomegaly, and neutropenia; experiencing more than one rheumatic pathology is a rare phenomenon estimated between 0.01-2%. Objective. Describe the comprehensive nursing care process in an adolescent with Rhupus and Felty's syndrome, under the adaptation model of Callista Roy. Methodology. Nursing case study of a 15-year-old patient selected in pediatric hospitalization, with prior informed consent; intervened through the structured nursing care process according to the taxonomy of the North American Nursing Diagnosis Association, the Nursing Outcomes Classification, and the Nursing Interventions Classification, with in-hospital interventions and follow-up through tele-nursing. Results. Improvement in ambulation and coping with problems evidenced by the increased well-being of the patient and the family. Conclusions. Faced with an unknown disease, the nursing care process, with direct interventions and continuous support, allows for comprehensive care to achieve the adaptation of the patient and her family.

Hydrogenated or oxyfunctionalized turpentine: options for automotive fuel components.

Many concerns, such as economic and technical viability and social and ethical aspects, must be considered for a feedstock selection for advanced biofuels. Industrialized countries promote the use of industrial waste or by-products for this purpose. In particular, turpentine has several properties which make it an attractive source for biofuels, including its possible industrial waste origin. Nevertheless, turpentine has shown some disadvantages when blended directly with diesel, especially because it increases the sooting tendency. On the contrary, some derivatives of turpentine can be suitable for diesel blends. Thus, the evaluation of their properties is necessary. In the present work, the properties of hydrogenated and oxyfunctionalized turpentine have been analysed and compared with the purpose of elucidating their benefits and drawbacks in diesel fuel applications, using European standards as a reference. The results show a promising application of both hydroturpentine and oxyturpentine as diesel components. While hydroturpentine significantly improves the diesel cold flow properties, oxyturpentine noticeably reduces the sooting tendency.

Influence of molecular structure of oleoresin-derived compounds on flame properties and emissions from laminar flames.

The search for renewable fuels or components which may improve or replace fossil fuels is an important step towards a sustainable future. In particular, the pine oleoresin produced by conifer trees, which is composed by turpentine oil and non-volatile rosin, may be transformed into alternative fuels. In this work, combustion of six molecules which can be obtained from oleoresin either by distillation (i.e., α- and ß-pinene) or by further oxyfunctionalization (nopol, terpineol, myrtenol, and borneol) was studied to assess the potential of pine oleoresin as raw material for biofuels. Emission indices of the main pollutants (carbon monoxide-CO, unburned hydrocarbons-UHC, and nitrogen oxides-NOx) were obtained in non-premixed co-flow laminar flames of the oleoresin-derived molecules blended with n-heptane. The main characteristics of the flames (i.e., temperature and height) were also determined. Significant increase in flame temperature and reduction in CO and UHC emissions with respect to n-heptane were observed with nopol, terpineol, and myrtenol, along an increase in NOx emissions, suggesting an improvement in combustion performance. In addition, differences in emission indices, evidenced for these molecules (even between α- and ß-pinene), suggest the importance of the molecular structure in the combustion reaction.
