Infective endocarditis in intravenous drug abusers: an update

Infective endocarditis despite advances in diagnosis remains a common cause of hospitalization, with high morbidity and mortality rates. Through literature review it is possible to conclude that polymicrobial endocarditis occurs mainly in intravenous drug abusers with predominance in the right side of the heart, often with tricuspid valve involvement. This fact can be associated with the type of drug used by the patients; therefore, knowledge of the patient's history is critical for adjustment of the therapy. It is also important to emphasize that the most common combinations of organisms in polymicrobial infective endocarditis are: Staphylococcus aureus, Streptococcus pneumonia and Pseudomonas aeruginosa, as well as mixed cultures of Candida spp. and bacteria. A better understanding of the epidemiology and associated risk factors are required in order to develop an efficient therapy, although PE studies are difficult to perform due to the rarity of cases and lack of prospective cohorts.This work was supported by Portuguese Foundation for Science and Technology (FCT) through the grants SFRH/BPD/47693/2008, SFRH/BPD/20987/2004 and SFRH/BPD/72632/2010 attributed to Claudia Sousa, Claudia Botelho and Diana Rodrigues, respectively

Rural-Urban Differences in Esophagectomy for Cancer

Introduction. Patients who are socioeconomically disadvantaged or in rural areas may not pursue surgery at high-volume centers, where outcomes are better for some complex procedures. The objective of this study was to determine and compare rural and urban patient differences and outcomes after undergoing esophagectomy for cancer. Methods. An analysis of the Healthcare Cost and Utilization Project National Inpatient Sample (HCUP NIS) database was performed, capturing adult patients with esophageal cancer who underwent esophagectomy. Patients were stratified into rural or urban groups by the National Center for Health Statistics Urban-Rural Classification Scheme. Demographics, hospital variables, and outcomes were compared. Results. A total of 2,877 patients undergoing esophagectomy for esophageal cancer were captured by the database, with 228 (7.92%) rural and 2,575 (89.50%) urban patients. The rural and urban groups had no difference in age, race, insurance status, and many common comorbidities. Major outcomes of mortality and length of stay were similar for both rural and urban patients (3.95% versus 4.27%, p=0.815) and (15.75±13.22 versus 15.55±14.91 days, p=0.828), respectively. There was a trend for rural patients to be more likely to discharge home (35.96% versus 29.79%, OR 0.667 [95%CI 0.479-0.929]; p=0.0167). Conclusions. This retrospective administrative database study indicates that rural and urban patients receive equivalent postoperative care after undergoing esophagectomy. The findings are reassuring as there does not appear to be a disparity in major outcomes depending on the location of residence, but further studies are necessary to assure equitable treatment for rural patients
