Regionalization of the surgical care of children: a risk-adjusted comparison of hospital surgical outcomes by geographic areas.
There is an ongoing debate among pediatric surgeons regarding the need or lack thereof to centralize the surgical care of children to high-volume children's centers. Risk-adjusted comparisons of hospitals performing pediatric surgery are needed. ⋯ The present analysis is a novel risk-adjusted assessment of the performance of hospitals delivering pediatric surgical care. By identifying the existence of multiple poor performing outlier hospitals, this study provides valuable data for discussion as health care delivery systems continue to debate optimal resource distribution and regionalization of the surgical care of children.

We have recently demonstrated that in a rodent model of lipopolysaccharide (LPS)-induced shock, an increase in circulating citrullinated histone H3 (Cit H3) is associated with lethality of sepsis, and treatment with suberoylanilide hydroxamic acid (SAHA), a histone deacetylase (HDAC) inhibitor (HDACI), significantly improves survival. However, the role of Cit H3 in pathogenesis and therapeutics of sepsis are largely unknown. The present study was designed to test whether treatment with HDACI could inhibit cellular Cit H3 production, and inhibition of peptidylarginine deiminase (PAD, an enzyme producing Cit H3) with Cl-amidine (PAD inhibitor) or neutralization of blood Cit H3 with anti-Cit H3 antibody could improve survival in a clinically relevant mouse model of cecal ligation and puncture (CLP)-induced septic shock. ⋯ Inhibition of HDAC or PAD significantly suppresses Cit H3 production in vitro and improves survival in vivo. Neutralization of Cit H3 significantly improves survival in septic mice. Collectively, our findings indicate for the first time that Cit H3 could not only serve as a potential biomarker, but also a novel therapeutic target in sepsis.

Over the past 2 decades, laparoscopy has been established as a superior technique in many general surgery procedures. Few studies, however, have examined the impact of the use of a laparoscopic approach in patients with symptomatic congestive heart failure (CHF). Because pneumoperitoneum has known effects on cardiopulmonary physiology, patients with CHF may be at increased risk. This study examines current trends in approaches to patients with CHF and effects on perioperative outcomes. ⋯ For patients with CHF, an open operative approach seems to be utilized more frequently in general surgery procedures, particularly in urgent/emergent cases. Despite these patterns and apparent preferences, laparoscopy seems to offer a safe alternative in appropriately selected patients. Because morbidity and mortality were considerable regardless of approach, further understanding of appropriate management in this population is necessary.

Sepsis has a profound impact on the inflammatory and hemostatic systems. In addition to systemic inflammation, it can produce disseminated intravascular coagulation, microvascular thrombosis, consumptive coagulopathy, and multiple organ failure. We have shown that treatment with suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor (HDACI), improves survival in a lethal model of cecal ligation and puncture (CLP) in mice, but its effect on coagulation remains unknown. The goal of this study was to quantify the impact of SAHA treatment on coagulopathy in sepsis. ⋯ SAHA treatment enhances survival and attenuates sepsis-associated coagulopathy by improving fibrin cross-linkage, rate of clot formation, platelet function, and clot strength. HDACI may represent a novel therapeutic strategy for correcting sepsis-associated coagulopathy.

Increasing use of Internet resources for health information is important in promoting patient involvement in medical care and decision-making. The National Institutes of Health and American Medical Association have recommended that patient health information should be written at a sixth-grade reading level. This study evaluates the readability of the most commonly used Internet resources for the operative treatment of breast cancer in the context of average American literacy. ⋯ Online patient resources for breast cancer surgery exceed recommended reading levels and are too difficult to be understood by a large portion of the United States population.
