Disparate lower-extremity ultrasonography (LUS) screening practices among trauma institutions reflecta lack of consensus regarding screening indications and whether screening improves outcomes. We hypothesized that LUS screening for deep-vein thrombosis (DVT) is not associated with a reduced incidence of pulmonary embolism (PE). ⋯ LUS in trauma patients is not associated with a change in the incidence of PE. Aggressive LUS DVT screening protocols appear to detect many clinically insignificant DVTs for which subsequent therapeutic intervention may be unnecessary, and the use of these protocols should be questioned.

Comparative Study
Net health benefit of hepatic resection versus intraarterial therapies for neuroendocrine liver metastases: A Markov decision model.
Management of patients with neuroendocrine liver metastasis (NELM) remains controversial. We sought to compare the net health benefit (NHB) of hepatic resection (HR) versus intraarterial therapy (IAT) among patients with NELM. ⋯ A Markov decision model demonstrated that HR was the preferred strategy among patients with symptomatic NELM, regardless of hepatic disease burden. In contrast, IAT should be preferred for patients with large volume nonfunctioning/asymptomatic NELM.

Geriatric emergency general surgery: Survival and outcomes in a low-middle income country.
Geriatric patients remain largely unstudied in low-middle income health care settings. The purpose of this study was to compare the epidemiology and outcomes of older versus younger adults with emergency general surgical conditions in South Asia. ⋯ Understanding unique needs of geriatric patients is critical to enhancing the management and prioritization of appropriate care in developing settings.

Decreasing readmissions has become a focus of emerging efforts to improve the quality and affordability of health care. However, little is known about reasons for readmissions after major cancer surgery in the expanding elderly population (≥65 years) who are also at increased risk of adverse operative events. We sought to identify (1) the extent to which older age impacts readmissions and (2) factors predictive of 30- and 90-day readmissions after major cancer surgery among older adults. ⋯ In this large, multihospital study of older adults, multiple morbidities, procedure type, greater number of complications, and the treating hospital predicted 30- and 90-day readmissions. These findings point toward the potential impact of hospital-level factors behind readmission. Our results also heighten the importance of assessing the influence of readmission on other important cancer care metrics, namely, patient-reported outcomes and the completion of adjuvant systemic therapies.

Calpain is a family of cysteine proteases that has an important role in the initiation, regulation, and execution of cell death. Our recent studies using a hypercholesterolemic swine model demonstrated that in the setting of the metabolic syndrome, calpain inhibition (CI) improved collateral-dependent perfusion and increased expression of proteins implicated in angiogenesis and vasodilation. In this study, we hypothesized that CI (by MLD28170) would decrease myocardial apoptosis in the same model. ⋯ In the setting of hypercholesterolemia, CI decreases apoptosis and the expression of proteins in proapoptotic signaling pathways. CI also increased expression of proteins implicated in anti apoptotic pathways and improves oxidative stress in ischemic myocardial tissue.
