Obesity, like multiple trauma, is associated with an inflammatory condition that leads to an immunodeficient state. Obese trauma patients are thus thought to be at higher risk of infection compared to patients of normal body mass. Despite this risk, studies to date have not defined obesity as an independent risk factor for infection in trauma patients. ⋯ In this retrospective study, obesity was shown to be an independent risk factor for nosocomial infection after trauma. Prospective studies would clarify the reasons associated with this increased risk of infections in obese trauma patients.

Comparative Study
Comparison of survival after sublobar resections and ablative therapies for stage I non-small cell lung cancer.
Lobectomy is the standard therapy for patients with stage I non-small cell lung cancer (NSCLC). Recently, sublobar resections (SLR), radiofrequency ablation (RFA), and percutaneous cryablation therapy (PCT) for high-risk patients unfit for standard resection have been reported. This study compares all 3 modalities in stage I NSCLC. ⋯ This experience suggests comparable survival after sublobar resections and ablative therapies at 3 years. Ablative therapies appear to be a reasonable alternative in high-risk patients not fit for surgery. However, larger randomized studies with longer follow-up are needed to make recommendations for therapy.

Biliary complications (BCs) are a major cause of morbidity and mortality after living donor liver transplantation (LDLT). They occur because the graft hepatic ducts are often small, thin walled, multiple, and may become ischemic during transection. ⋯ By providing a graft with a well-vascularized hepatic duct or ducts with a sheath of supporting tissue that holds sutures well, the HPGS approach minimizes the incidence and severity of BCs in LDLT.

Preoperative risk assessment is important yet inexact in older patients because physiologic reserves are difficult to measure. Frailty is thought to estimate physiologic reserves, although its use has not been evaluated in surgical patients. We designed a study to determine if frailty predicts surgical complications and enhances current perioperative risk models. ⋯ Frailty independently predicts postoperative complications, length of stay, and discharge to a skilled or assisted-living facility in older surgical patients and enhances conventional risk models. Assessing frailty using a standardized definition can help patients and physicians make more informed decisions.
