Phantom limb pain (PLP) and residual limb pain (RLP) are debilitating sequelae of major limb amputation. Targeted muscle reinnervation (TMR), when performed at the time of amputation, has been shown to be effective for management of this pain; however, its long-term effects and the longitudinal trend of patient-reported outcomes is unknown. The purpose of this study was to characterize the longitudinal patient-reported outcomes of pain and quality of life following TMR at the time of initial amputation.

A prospective case series of patients undergoing major limb amputation with TMR performed at the time of amputation were followed from October 2015 to December 2020 with outcomes measured 3, 6, 12, and 18 months or longer after amputation and TMR. Outcomes included patient-reported severity of PLP and RLP as measured by the numeric rating scale (NRS). Secondary outcomes included the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference and Pain Behavior Questionnaires.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) achieves temporary hemorrhage control via aortic occlusion. Existing REBOA literature focuses on blunt trauma without a clearly defined role in penetrating trauma. This study compared clinical/injury data and outcomes after REBOA in penetrating vs blunt trauma.

All patients in the Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery (AORTA) database, an observational American Association for the Surgery of Trauma dataset of trauma patients requiring aortic occlusion, who underwent REBOA were included (January 2014 through February 2021). Study groups were defined by mechanism penetrating vs blunt. Subgroup analysis was performed of patients arriving with vital signs. Univariable/multivariable analyses compared injuries and outcomes.

Seven hundred fifty-nine patients underwent REBOA 152 (20%) penetrating and 607 (80%) blunt. Patients undergoing penetrating REBOA were less severely injured (injury severity score 25 vs 34; p &y be most beneficial among patients with vital signs. Because hemorrhage source, catheter insertion setting, and deployment zone varied significantly between groups, existing blunt REBOA data may not be appropriately extrapolated to penetrating trauma. Further study of REBOA as a means of aortic occlusion in penetrating trauma is needed.
Despite lower injury severity, REBOA was significantly less likely to improve or stabilize hemodynamics after penetrating trauma. Among patients arriving alive, however, outcomes were comparable, suggesting that penetrating REBOA may be most beneficial among patients with vital signs. Because hemorrhage source, catheter insertion setting, and deployment zone varied significantly between groups, existing blunt REBOA data may not be appropriately extrapolated to penetrating trauma. Further study of REBOA as a means of aortic occlusion in penetrating trauma is needed.
Bariatric surgery induces changes in gut microbiota that have been suggested to contribute to weight loss and metabolic improvement. selleck However, whether preoperative gut microbiota composition could predict response to bariatric surgery has not yet been elucidated.

Seventy-six patients who underwent sleeve gastrectomy were classified according to the percentage of excess weight loss (%EWL) 1 year after surgery in the responder group >50%EWL (n=50) and the nonresponder group <50%EWL (n=26). Patients were evaluated before surgery, and 3 months and 1 year after surgery. Gut microbiota composition was analyzed before surgery (n=76) and 3 months after bariatric surgery (n=40).

Diversity analysis did not show differences between groups before surgery or 3 months after surgery. Before surgery, there were differences in the abundance of members belonging to Bacteroidetes and Firmicutes phyla (nonresponder group enriched in Bacteroidaceae, Bacteroides, Bacteroides uniformis, Alistipes finegoldii, Alistipes alut microbiota could have an impact on bariatric surgery outcomes. Prevotella-to-Bacteroides ratio could be used as a predictive tool for weight loss trajectory. Early after surgery, patients who experienced successful weight loss showed an enrichment in taxa related to beneficial effects on host metabolism.
The influence of laparoscopic ultrasonography (LUS) on the operative management of patients during laparoscopic cholecystectomy (LC) has not been examined in a large unselected series.

Seven hundred eight-five consecutive LC operations were reviewed to determine whether the findings of LUS for bile duct imaging altered operative management. Patients were analyzed according to the primary indication for imaging anatomic identification (group I), possible common bile duct stones (group II), and routine use absent other indications (group III).

LUS demonstrated the cystic duct-common bile duct junction, the common hepatic duct, the common bile duct to the ampulla, and the right hepatic artery in 95.8% of cases. Among 56 of 111 (50%) patients in group I for whom initial dissection failed to result in adequate anatomic identification, subsequent LUS provided sufficient anatomic identification to allow completion of a laparoscopic operation in 87.5%. Group I patients were more likely to have acute cholecystitsion for an alternate operative strategy. When performed primarily for common bile duct stones or as routine practice, LUS results in CBDE for a limited proportion of patients.
Enhanced recovery programs (ERPs) are associated with a lower morbidity rate and a shorter length of stay. The present study's objective was to determine whether an ERP is feasible and effective for patients undergoing early cholecystectomy for grade I or II acute calculous cholecystitis.

A 2-step multicenter study was performed. In the first step (the feasibility study), patients were consecutively included in a dedicated, prospective database from March 2019 until January 2020. The primary endpoint was the ERP's feasibility, evaluated in terms of the number and nature of the ERP components applied. During the second step, the ERP's effectiveness in acute calculous cholecystitis was evaluated in a case-control study. The ERP+ group comprised consecutive patients who were prospectively included from March 2019 to November 2020 and compared with a control (ERP-) group of patients extracted from the ABCAL randomized controlled trial treated between May 2010 and August 2012 and who had not participated in a dedicated ERP.

During the feasibility study, 101 consecutive patients entered the ERP with 17 of the 20 ERP components applied. During the effectiveness study, 209 patients (ERP+ group) were compared with 414 patients (ERP- group). The median length of stay was significantly shorter in the ERP+ group (3.1 vs 5 days; p < 0.001). There were no intergroup differences in the severe morbidity rate, mortality rate, readmission rate, and reoperation rate.

Implementation of an ERP after early cholecystectomy for acute calculous cholecystitis appeared to be feasible, effective, and safe for patients. The ERP significantly decreased the length of stay and did not increase the morbidity rate.

The impact of chronic kidney disease (CKD) on surgery is still not well defined. We sought to characterize the association of preoperative CKD with 30-day mortality after hepatic resection.

Patients included in the American College of Surgeons (ACS) NSQIP who underwent hepatectomy between 2014 and 2018 were identified. Kidney function was stratified according to the "Kidney Disease Improving Global Outcomes" (KDIGO) Classification G1, normal/high function (estimated glomerular-filtration-rate ≥ 90 ml/min/1.73m2); G2-3, mild/moderate CKD (89-30 ml/min/1.73m2); G4-5, severe CKD (≤ 29 ml/min/1.73m2).

Overall, 18,321 patients were included. Older patients (ie more than 70 years old) and those with serious medical comorbidities (ie American Society of Anesthesiologists [ASA] class 3) had an increased incidence of severe CKD (both p < 0.001). Patients with G2-3 and G4-5 CKD were more likely to have a prolonged length of stay and to experience postoperative complications (both p < 0.001). Adjusted odds of 30-day mortality increased with the worsening CKD (p = 0.03). The degree of CKD was able to stratify patients within the NSQIP risk calculator. Among patients who underwent major hepatectomy for primary cancer, the rate of 30-day mortality was 2-fold higher with G2-3 and G4-5 CKD vs normal kidney function (p = 0.03).

The degree of CKD was related to the risk of complications and 30-day mortality after hepatectomy. CKD classification should be strongly considered in the preoperative risk estimation of these patients.

Financial toxicity (FT) depicts the burden of cancer treatment costs and is associated with lower quality of life and survival in breast cancer patients. We examined the relationship between geospatial location, represented by rurality and Area Deprivation Index (ADI), and risk of FT.

A single-institution, cross-sectional study was performed on adult female surgical breast cancer patients using survey data retrospectively collected between January 2018 and June 2019. Chart reviews were used to obtain patient information, and FT was identified using the COmprehensive Score for Financial Toxicity questionnaire, which is a validated instrument. Patients' home addresses were used to determine rurality using the Rural Urban Continuum Codes and linked to national ADI score. ADI was analyzed in tertiles for univariate statistical analyses, and as a continuous variable to develop multivariable logistic regression models to evaluate the independent associations of geospatial location with FT.

A total of 568 surgby the ADI. However, in adjusted analyses, rurality was not significantly associated with FT. ADI can be useful for preoperative screening of at-risk populations and the targeted deployment of community-based interventions to alleviate FT.
Determining the risk of developing severe acute pancreatitis (AP) on presentation to hospital is difficult but vital to enable early management decisions that reduce morbidity and mortality. The objective of this study was to determine global gene expression profiles of patients with different acute pancreatitis severity to identify genes and molecular mechanisms involved in the pathogenesis of severe AP.

AP patients (n = 87) were recruited within 24 hours of admission to the Emergency Department and were confirmed to exhibit at least 2 of the following features (1) abdominal pain characteristic of AP, (2) serum amylase and/or lipase more than 3-fold the upper laboratory limit considered normal, and/or (3) radiographically demonstrated AP on CT scan. Severity was defined according to the Revised Atlanta classification. Thirty-two healthy volunteers were also recruited and peripheral venous blood was collected for performing RNA-Seq.

In severe AP, 422 genes (185 upregulated, 237 downregulated) were significantly differentially expressed when compared with moderately severe and mild cases.
