Thyroid surgery is associated with low mortality and morbidity and often is performed in an ambulatory setting. The majority of patients undergoing thyroidectomy have an uncomplicated outcome, but common comorbidities may increase mortality and morbidity. Due to low complication rates, studies using single surgeon or single institutional data to identify risk factors for adverse outcomes may be limited by inadequate patient volume. ⋯ Thyroid surgery is generally safe. Common comorbidities significantly increase the risk of adverse outcomes and death. Clinically applicable risk calculation based on overall health may improve patient selection, surgical management, and informed consent.

Multicenter Study
Mortality and management of surgical necrotizing enterocolitis in very low birth weight neonates: a prospective cohort study.
Necrotizing enterocolitis (NEC) is a leading cause of death in very low birth weight (VLBW) neonates. The overall mortality of NEC is well documented. However, those requiring surgery appear to have increased mortality compared with those managed medically. The objective of this study was to establish national birth-weight-based benchmarks for the mortality of surgical NEC and describe the use and mortality of laparotomy vs peritoneal drainage. ⋯ Fifty-two percent of VLBW neonates with NEC underwent surgery, which was accompanied by a substantial increase in mortality. Regardless of birth weight, surgical NEC showed a plateau in mortality at approximately 30%. Laparotomy was the more frequent method of treatment (69%) and of those managed by drainage, 46% also had a laparotomy. The laparotomy alone and drainage with laparotomy groups had similar mortalities, while the drainage alone treatment cohort was associated with the highest mortality.

The incidence of community-acquired Clostridium difficile (CACD) is increasing in the United States. Many CACD infections occur in the elderly, who are predisposed to poor outcomes. We aimed to describe the epidemiology and outcomes of CACD in a nationally representative sample of Medicare beneficiaries. ⋯ Nearly half of the Medicare beneficiaries admitted with CACD have no recent antibiotic exposure. High mortality and readmission rates suggest that the burden of C difficile on patients and the health care system will increase as the US population ages. Additional efforts at primary prevention and eradication might be warranted.

The aim of this study was to compare outcomes of patients who sustained burn and ostensible inhalation injuries while on home oxygen therapy with those suffering equivalent injuries via other mechanisms. ⋯ Injury secondary to smoking on home oxygen therapy is a perennial problem, and guidelines for prescribing home oxygen therapy for smokers should be reassessed. Despite underlying lung disease, patients in our series did as well as patients without COPD who sustained similar injuries.

Epidemiologic studies have shown that individuals who consume low to moderate alcohol have a lower risk of cardiovascular disease developing compared with abstainers. Although experimental studies confirmed this observation, the effect of alcohol on ischemic myocardium is still unclear. We developed a clinically relevant animal model of chronic myocardial ischemia to investigate the effects of moderate alcohol consumption on the myocardium. ⋯ Alcohol consumption down-regulates apoptosis and promotes cell survival in the ischemic and nonischemic myocardium. Alcohol also modulates MTOR signaling, which regulates senescence and apoptosis. Perhaps MTOR and apoptosis regulation is another mechanism by which moderate EtOH consumption is cardioprotective.
