Gun violence, particularly in the form of mass shooting events (MSE), is a growing, significant public health crisis in the US. Whether stricter gun laws decrease MSE is not known. We hypothesized that stronger state gun laws would be associated with lower MSE incidence. ⋯ Strength of state gun law grades does not affect MSE incidence, even after correction for population size. This suggests that legislation by itself is not an effective prevention measure and other broader and meaningful primary gun violence interventions are needed.

Role of Fibrinogen in Trauma-Induced Coagulopathy.
Fibrinogen is the first coagulation factor to decrease after massive hemorrhage. European massive transfusion guidelines recommend early repletion of fibrinogen; however, this practice has not been widely adopted in the US. We hypothesize that hypofibrinogenemia is common at hospital arrival and is an integral component of trauma-induced coagulopathy. ⋯ Hypofibrinogenemia is common after severe injury and predicts MT. Cryoprecipitate transfusion results in the most expeditious correction. Earlier administration of cryoprecipitate should be considered in MT protocols.

Circulating tumor DNA (ctDNA) is a promising biomarker for patients undergoing hepatectomy for colorectal liver metastases (CLM). We hypothesized that post-hepatectomy ctDNA detection would identify patients at highest risk for early recurrence of CLM. ⋯ Postoperative ctDNA detection is associated with early recurrence 1 year or earlier after curative-intent hepatectomy for CLM, and RAS/TP53 co-mutations result in a more than 3-fold increased risk for postoperative ctDNA positivity. This highlights the complementary effect of tumor tissue and circulating mutational profiling for patients with CLM.

Pancreatic neuroendocrine tumor (PNET) survival outcomes differ by race. Current recommendations for surveillance of PNETs less than 2 cm in size are based on low malignant potential and low rates of lymph node metastases (LNM). We investigated whether these guidelines are universally applicable regardless of race. ⋯ The current recommendation for surveillance of PNETs of less than 2 cm in size is likely based on a low rate of LNM seen in a predominantly White population. The incidence of LNM in Black patients with tumors less than 2 cm in size is clinically relevant and concerning. Current guidelines may not be universally applicable, and a more aggressive approach to resection in Black patients with small PNETs may be warranted.

This prospective study was designed to compare quality of life (QoL) among patients who underwent open (O-PD) vs minimally invasive pancreaticoduodenectomy (MI-PD), using a combination of validated qualitative and quantitative methodologies. ⋯ Using a novel combination of qualitative and quantitative analyses in patients undergoing PD, we found no association between operative approach and QoL in patients who underwent O-PD vs MI-PD. Given the increasing use of minimally invasive techniques for PD and the steep learning curve associated with these techniques, continued assessment of patient benefit is critical.
