Randomized Controlled Trial
Randomized controlled trial of surgical rib fixation to non-operative management in severe chest wall injury.
To compare the effectiveness of surgical stabilization of rib fractures (SSRFs) to nonoperative management in severe chest wall injury. ⋯ In severe chest wall injury, even in the absence of clinical flail chest, the majority of patients still reported moderate to extreme pain and impairment of usual physical activity at one month. SSRF increased hospital LOS and did not provide any quality of life benefit for up to 6 months.

Develop a predictive model to identify patients with 1 pathologic lymph node (pLN) versus >1 pLN using machine learning applied to gene expression profiles and clinical data as input variables. ⋯ Gene expression profiles together with clinical variables can distinguish melanoma metastasis patients with 1 pLN versus >1 pLN. Future models trained using positron emission tomography/computed tomography imaging, gene expression, and relevant clinical variables may further improve accuracy and may predict patients who can be managed with a targeted LN excision rather than a complete TLND.

Multicenter Study
Demystifying BRAF Mutation Status in Colorectal Liver Metastases: A Multi-institutional, Collaborative Approach to 6 Open Clinical Questions.
To investigate the clinical implications of BRAF -mutated (mut BRAF ) colorectal liver metastases (CRLMs). ⋯ Although surgery may be futile in patients with BRAF -mutated CRLM and concurrent extrahepatic disease, resection of converted disease resulted in encouraging survival in the absence of extrahepatic spread. Importantly, second hepatectomy in select patients with recurrence was associated with improved outcomes. Finally, MSI-high status identifies a better prognostic group, with regard to RFS while patients with non-V600E mutations have excellent prognosis.

Randomized Controlled Trial Multicenter Study
Prophylactic Mesh Placement During Formation of an End-colostomy Long Term Rct on Effectiveness And Safety.
The aim of this study was to determine if prophylactic mesh placement is an effective, safe, and cost-effective procedure to prevent parastomal hernia (PSH) formation in the long term. ⋯ Prophylactic mesh placement during the formation of an end-colostomy is a safe procedure but does not reduce the incidence of PSH after 5 years of follow-up. It does, however, delay the onset of PSH without a significant difference in morbidity, mortality, or quality of life, and seems to be cost-effective.
