Objetivo. Evaluar el efecto del cobre sobre el comportamiento reproductivo de novillas lecheras. Materiales y métodos. El trabajo se realizó en fincas de la provincia de Villa Clara, en dos etapas y con 210 novillas. En la primera se estudiaron 120 novillas divididas en dos grupos de 60 animales cada uno. El grupo A, control y el B, tratado con 2 ml de CuSO4 (2.5%) subcutáneamente. En la segunda etapa se estudiaron 90 novillas divididas en tres grupos de 30 animales cada uno, el grupo A, control; el B, fue tratado con 2 ml de CuSO4 (2.5%) subcutáneamente y el grupo C, se trató con acupuntura utilizando 0.1 ml de dicho producto subcutáneamente en el punto Pahuai; en ambas etapas los animales del grupo A, no recibieron ningún tratamiento y a los animales tratados, grupos B y C se les repitió el tratamiento cada 60 días en dos aplicaciones más. Los análisis hemoquímicos se efectuaron en los laboratorios de la Facultad de Ciencias Agropecuarias de la Universidad Central de Las Villas. Resultados. Los animales aumentaron significativamente los niveles del cobre en suero sanguíneo (p

IntroductionBurnout is characterized by emotional exhaustion, depersonalization and reduced personal accomplishment, resulting from the inability to cope with chronic job stress. The literature suggests that staffs working in adult oncology are at risk of burnout. At the same time, research found that pediatric staff experiences a different set of stressors when compared with colleagues working in adult oncology. However, no studies were identified which directly compared prevalence and sources of Burn-out on pediatric and adult oncology staff.ObjectivesTo compare the differences on prevalence and sources of burnout between pediatric and adult oncology multidisciplinary teams.MethodsPediatric and adult oncology professionals, including medical and nursing from a Portuguese oncology center completed the Portuguese version of the Copenhagen Burnout Inventory. Data was analyzed using SPSS.ResultsSince the study is currently ongoing the authors will only be able to provide final results and conclusions by the time of submission of our work presentation, in March 2016. However, according to the literature available, we are expecting to found symptoms of Burnout in the superior limit of normality, with differences in the major sources of stress between adult and pediatric professionals.ConclusionThe differences in the challenges experienced by adult and pediatric teams highlight the importance of adequate prevention strategies to specific needs of each unit. Further investigation of stress across a wider range of professional disciplines is required in order to explore this gap.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionBurnout is a condition characterized by emotional exhaustion, depersonalization and reduced personal accomplishment, resulting from the inability to cope with chronic job stress. Healthcare providers at pediatric oncology units, who care for children with life-threatening illnesses, are exposure to high levels of stress, which increases the risk for developing burnout, with consequences in their personal health and quality of patient care.ObjectiveTo assess the prevalence and sources of burnout on a multidisciplinary team of a pediatric oncology unit.MethodsParticipants were a convenience sample of 16 pediatric oncology professionals, including medical, nursing, and related health staff from a Portuguese pediatric oncology center. Participants completed the Portuguese version of the Copenhagen Burnout Inventory.ResultsAll three subscales that compose this Inventory were found to have burnout below normal levels (cut-off ≥ 50 points). However, personal and work-related subscales showed mean values in the superior limit of normality (48 ± 14, 18 points and 49, 48 ± 12, 23 points, respectively). Nevertheless, when analyzed the patient-related subscale, we found low levels of burnout in the majority of responders. These findings are similar to the existing literature, which suggests that patient care and interactions with children are the least stressful aspect of working in this specialty.ConclusionDespite the high levels of stress exposure in pediatric oncology units, results suggest that the majority of professionals are not actually in burnout. However, the obtained values advice for the need of prevention and workplace approaches to staff's well-being and stress reduction, in order to avoid burnout development.Disclosure of interestThe authors have not supplied their declaration of competing interest.
