Introduction:Burnout is a psychological syndrome, characterized by a state of high emotional exhaustion, high depersonalization and low personal accomplishment, which leads to erosion of personal, professional and health values. This study reports the incidence of burnout in Portuguese Healthcare professionals. Material and Methods: Burnout in Portugal's health professionals was assessed with the Maslach Burnout Inventory -Human Services Survey, using a zero (never) to six (always) ordinal scale, on a sample of 1 262 nurses and 466 physicians with mean age of 36.8 year (SD = 12.2) and 38.7 (SD = 11.0), respectively. Participants came from all national districts (35% Lisbon, 18% Oporto, 6% Aveiro, 6% Setúbal, 5% Coimbra, 5% Azores and Madeira), working in hospitals (54%), Families' Health Units (30%), Personalized Health Units (8%) and other public or private institutions (8%).Results: Analysis of MBI-HSS scores, stratified by district, revealed that both types of professionals had moderate to high levels of burnout (M = 3.0, SD = 1.7) with no significant differences between the two groups. Vila Real (M = 3.8, SD = 1.7) and Madeira (M = 2.5, SD = 1.5) were the regions where burnout levels were higher and lower, respectively. Burnout levels did not differ significantly between Hospital, Personalized Health Units and Families' Health Centers. Professionals with more years in the function were less affected by Burnout (r = -0.15). No significant association was observed with the duration of the working day (r = 0.04). The strongest predictor of burnout was the perceived quality of working conditions (r = -0.35). Discussion: The occurrence of the burnout syndrome in Portuguese health professionals is frequent, being associated with a poor working conditions perception and reduced professional experience. The incidence of the burnout syndrome shows regional differences which may be associated with different and suboptimal conditions for health care delivery. Results suggest the need for interventions ARTIGO ORIGINAL

The side-effects of pesticides (insecticides, fungicides, herbicides and plant growth regulators) used on cotton were tested on adults and pupae of Trichogramma pretiosum Riley reared in the laboratory on two different hosts, the Angoumois grain moth (Sitotroga cerealella Olivier) and the Mediterranean flour moth (Ephestia kuehniella (Zeller)). The eggs of the host enclosing the parasitoid pupae received direct pesticide sprays, while the adults of the parasitoid were exposed to the pesticides through contact with residues on sprayed eggs offered to parasitism. Alpha-cypermethrin, carbosulfan, deltamethrin, endosulfan, profenofos and zeta-cypermethrin were highly noxious to the parasitoid, significantly reducing the percentage of emergence and parasitism of T. pretiosum developing in E. kuehniella or S. cerealella eggs. However, the pupal stage of the parasitoid developing in S. cerealella eggs was less susceptible to alpha-cypermethrin and deltamethrin. Lufenuron and metamidophos greatly reduced the percentage of adult emergence from eggs of both hosts, while novaluron only interfered on this variable when the wasps were developing in E. kuehniella eggs. However, lufenuron and monocrotophos had no effect on the parasitoid pupae of T. pretiosum developing in E. kuehniella eggs. Chlorfluazuron, diafenthiuron, diflubenzuron, fentin hydroxide, mepiquat chloride, novaluron, thiacloprid and triflumuron did not affect T. pretiosum emergence when eggs of S. cerealella enclosing pupae of the wasps were surface treated. The pesticides azoxystrobin, carbendazin + thiram, mepiquat chloride and novaluron had no effect on the ability of the wasps to parasitise E. kuehniella eggs. However, only mepiquat chloride did not affect the percentage of F1 wasps emerging from E. kuehniella eggs. The remaining pesticides moderately reduced the percentage of emergence and parasitism of the wasps when they had contact with the chemicals during their pupal or adult stage. Thus there were differences in pesticide toxicity according to the host used for parasitoid development. These differences were hypothesised to occur because of differences in egg morphology and parasitoid performance.
