Predictors of Burnout Among Physicians: Evidence From a National Study in Portugal.

The aims of this research on burnout among physicians were threefold, (1) to characterize the burnout symptoms' prevalence among Portuguese physicians, (2) to test the hypothesis that organizational demands and resources add, on top of other factors, to the explanatory level of burnout; and (3) to explore the predictors of organizational demands and resources. Data collection was conducted online at the national level in Portugal, with 9,176 complete replies and a response rate of 21%. Predictors stemming from theoretical models of an intra-individual, occupational, organizational, and socio-psychological nature were measured using an online/paper survey. Results were analyzed through a significantly modified version of the Maslach Burnout Inventory (MBI) after transformations to address the fit of this measure in this sample. Results show that 66% of physicians have high levels of emotional exhaustion, 33% high levels of depersonalization, and 39% high levels of decrease of personal accomplishment. Moreover, a first set of hierarchical multiple regression models with burnout symptoms reveals that organizational resources, demands of the relationship with the patients and of work schedule are consistently important predictors of emotional exhaustion and depersonalization on top of other theoretically relevant predictors. A second set of regression models with the organizational-level variables shows that, aside from organizational variables, other context variables, like procedural justice and teamwork, have the most substantial predictive value. These results highlight the importance of recognizing physicians' burnout as a phenomenon that is predicted by a wide variety of factors, but also the importance of attending to the particular role of circumstancial factors that may be addressed in future interventions.

Strongyloides stercoralis Gastric Ulcer: A Rare Cause of Upper Gastrointestinal Bleeding.

Strongyloidiasis is an infection caused by Strongyloides stercoralis. Gastrointestinal manifestations typically include duodenitis, chronic enterocolitis, and malabsorption, while gastric involvement is very rare. In this case report, the -authors present a case of upper gastrointestinal bleeding caused by a gastric ulcer with a challenging etiological diagnosis. In Portugal, there have been reports in the past century of autochthonous cases of S. stercoralis infection suggesting endemic zones, but with the current sanitation infrastructure strongyloidiasis is thought to be rare. A 56-year-old Caucasian male smoker with a history of significant weight loss presented to the emergency department with hema-temesis and abdominal pain. Upper endoscopy revealed a giant gastric ulcer with a macroscopic appearance suggestive of malignancy. Further investigation with CT scan highlighted gastric wall thickness and a spiculated lung lesion in the upper right lobe without lymph node involvement or metastatic disease. Bronchoscopy with bronchial brushing was performed. Histological examination identified squamous cell carcinoma of the lung and the patient was referred to Oncological Pneumology. Gastric ulcer biopsies ruled out malignancy and identified fragments of nematodes with inflammatory infiltrates and fibrinogranulocytic exudate, suggestive of S. stercoralis. Accordingly, the diagnosis of strongyloidiasis was made and further confirmed with molecular methods and serology. The giant gastric ulcer was affirmed to be caused by S. stercoralis infection and the patient was treated with ivermectin with improvement of epigastric pain. On reevaluation 6 weeks later the patient was asymptomatic, had gained weight, parasitological stool examinations were negative, and upper endoscopy showed complete ulcer healing. Further tests were done targeting risk factors for strongyloidiasis, and in addition to the presence of malignancy, other underlying causes for immunosuppression were ruled out. In this case report strongyloidiasis was manifested by gastric involvement with upper gastrointestinal bleeding in a patient who was subsequently diagnosed with squamous cell carcinoma of the lung.

A estrongiloidíase é uma infecção causada por Strongyloides stercoralis. As manifestações gastrointestinais tipicamente incluem duodenite, enterocolite crónica e má absorção, sendo o envolvimento gástrico muito raro. Neste caso clínico, os autores apresentam um caso de hemorragia digestiva alta causada por uma úlcera gástrica com um diagnóstico etiológico desafiante. Em Portugal no século passado existiram casos autóctones de infecção a S. stercoralis sugerindo zonas endémicas, mas com a actual infraestrutura de saneamento a estrongiloidíase é rara. Homem de 56 anos de idade, caucasiano, fumador, com história de perda ponderal significativa, admitido no Serviço de Urgência por hematemeses e dor abdominal. A endoscopia digestiva alta realizada revelou uma úlcera gástrica gigante com aparência macroscópica sugestiva de malignidade. A investigação subsequente com tomografia computadorizada (TC) destacou a presença de espessamento gástrico e uma lesão pulmonar espiculada no lobo superior direito, sem envolvimento ganglionar ou doença metastática. Foi realizada broncofibroscopia com escovado brônquico tendo o exame histológico identificado carcinoma pavimento celular do pulmão, pelo que o doente foi referenciado para a Pneumologia Oncológica. As biópsias da úlcera gástrica descartaram malignidade e identificaram fragmentos de nemátodes com infiltrados inflamatórios e exsudado fibrino-granulocítico, sugestivo de Strongyloides stercoralis. Consequentemente, foi feito o diagnóstico de estrongiloidíase, confirmado com métodos moleculares e sorologia. Admitiu-se que a úlcera gástrica gigante terá sido causada pela infecção por Strongyloides stercoralis e o doente foi tratado com ivermectina com melhoria da dor epigástrica. Em reavaliação, seis semanas depois, o doente estava assintomático, com ganho ponderal, os exames parasitológicos das fezes estavam negativos e a endoscopia digestiva alta mostrou cicatrização completa da úlcera. Foram realizados exames adicionais para investigação de factores de risco para estrongiloidíase, tendo sido excluídas outras causas de imunossupressão subjacente para além da presença de malignidade. Neste caso clínico, a estrongiloidíase manifestou-se por envolvimento gástrico com hemorragia digestiva alta num doente que foi posteriormente diagnosticado com carcinoma pavimento celular do pulmão.
