Objective: Breastfeeding is a highly demanding experience, especially for surgical residents who pump after returning to work. We believe that there are obstacles to pumping and opportunities exist to improve support for this group. The objective of this study was to understand the experience of breastfeeding surgery residents and find opportunities for increased support., Design: Surveys were sent out through the Association of Program Directors in Surgery for distribution among current residents. A survey was also conducted in a private group of surgeon mothers to identify those who had previously been breastfeeding during residency., Setting: All surveys were performed online with results collected in a REDCap web-based application., Participants: Participants were those who gave birth during their surgical residency., Results: 67% of the 246 survey respondents stated that they did not have adequate time for pumping and 56% rarely had access to a lactation room. 69% of mothers reported a reduction in milk supply and 64% stated that the time constraints of residency shortened the total duration they breastfed. 59% of women did not feel comfortable asking to pump., Conclusions: Surgical residents reported a lack of space, resources, and dedicated time for pumping. These deficiencies contribute to shorter breastfeeding duration. It is crucial to provide lactation rooms and to foster a supportive culture., (Copyright © 2023. Published by Elsevier Inc.)

Background: Blunt traumatic abdominal wall hernias (TAWH) occur in <1 % of trauma patients. Optimal repair techniques, such as mesh reinforcement, have not been studied in detail. We hypothesize that mesh use will be associated with increased surgical site infections (SSI) and not improve hernia recurrence., Materials and Methods: A secondary analysis of the Western Trauma Association blunt TAWH multicenter study was performed. Patients who underwent TAWH repair during initial hospitalization (1/2012-12/2018) were included. Mesh repair patients were compared to primary repair patients (non-mesh). A logistic regression was conducted to assess risk factors for SSI., Results: 157 patients underwent TAWH repair during index hospitalization with 51 (32.5 %) having mesh repair: 24 (45.3 %) synthetic and 29 (54.7 %) biologic. Mesh patients were more commonly smokers (43.1 % vs. 22.9 %, p = 0.016) and had a larger defect size (10 vs. 6 cm, p = 0.003). Mesh patients had a higher rate of SSI (25.5 % vs. 9.5 %, p = 0.016) compared to non-mesh patients, but a similar rate of recurrence (13.7 % vs. 10.5%, p = 0.742), hospital length of stay (LOS), and mortality. Mesh use (OR 3.66) and higher ISS (OR 1.06) were significant risk factors for SSI in a multivariable model., Conclusion: Mesh was used more frequently in flank TAWH and those with a larger defect size. Mesh use was associated with a higher incidence and risk of SSI but did not reduce the risk of hernia recurrence. When repairing TAWH mesh should be employed judiciously, and prospective randomized studies are needed to identify clear indications for mesh use in TAWH., Competing Interests: Declaration of Competing Interest The authors have no conflicts to report, (Copyright © 2023.

Introduction: Sarcopenia is a clinically relevant loss of muscle mass with implications of increased morbidity and mortality in adult trauma populations.  Our study aimed to evaluate loss of muscle mass change in adult trauma patients with prolonged hospital stays., Methods: Retrospective analysis using institutional trauma registry to identify all adult trauma patients with hospital length of stay >14 days admitted to our Level 1 center between 2010 and 2017. All CT images were reviewed, and cross-sectional area (cm 2 ) of the left psoas muscle was measured at the level of the third lumbar vertebral body to determine total psoas area (TPA) and Total Psoas Index (TPI) normalized for patient stature.  Sarcopenia was defined as a TPI on admission below gender specific thresholds of 5.45(cm 2 /m 2 ) in men and 3.85(cm 2 /m 2 ) in women.  TPA, TPI, and rates of change in TPI were then evaluated and compared between sarcopenic and non-sarcopenic adult trauma patients., Results: There were 81 adult trauma patients who met inclusion criteria. The average change in TPA was -3.8 cm 2 and TPI was -1.3 cm 2 . On admission, 23% (n = 19) of patients were sarcopenic while 77% (n = 62) were not. Non-sarcopenic patients had a significantly greater change in TPA (-4.9 vs. -0.31, p<0.0001), TPI (-1.7 vs. -0.13, p<0.0001), and rate of decrease in muscle mass (p = 0.0002). 37% of patients who were admitted with normal muscle mass developed sarcopenia during admission.  Older age was the only risk factor independently associated with developing sarcopenia (OR: 1.04, 95%CI 1.00-1.08, p = 0.045)., Conclusion: Over a third of patients with normal muscle mass at admission subsequently developed sarcopenia with older age as the primary risk factor. Patients with normal muscle mass at admission had greater decreases in TPA and TPI, and accelerated rates of muscle mass loss compared to sarcopenic patients., (Copyright © 2023.

Introduction: Large animal-related injuries (LARI) are relatively uncommon, but, nevertheless, a public hazard. The objective of this study was to better understand LARI injury patterns and outcomes., Materials and Methods: We performed a retrospective review of the 2016 National Trauma Data Bank and used ICD-10 codes to identify patients injured by a large animal. The primary outcome was severe injury pattern, while secondary outcomes included mortality, hospital length of stay, ICU admission, and mechanical ventilation usage., Results: There were 6,662 LARI included in our analysis. Most LARI (66%) occurred while riding the animal, and the most common type of LARI was fall from horse (63%). The median ISS was 9 and the most severe injuries (AIS ≥ 3) were to the chest (19%), head (10%), and lower extremities (10%). The overall mortality was low at 0.8%. Compared to non-riders, riders sustained more severe injuries to the chest (21% vs. 16%, p<0.001) and spine (4% vs. 2%, p<0.001). Compared to motor vehicle collisions (MVC), riders sustained fewer severe injuries to the head (10% vs. 12%, p<0.001) and lower extremity (10% vs. 12%, p=0.01). Compared to auto-pedestrian accidents, non-riders sustained fewer severe injuries to the head (11% vs. 19%, p<0.001) and lower extremity (10% vs. 20%, p<0.001)., Conclusion: Patients involved in a LARI are moderately injured with more complex injuries occurring in the chest, head, and lower extremities. Fall from horse was the most common LARI mechanism. Overall mortality was low. Compared to non-riders, riders were more likely to sustain severe injuries to the chest and spine. Severe injury patterns were similar when comparing riders to MVC and, given that most LARI are riding injuries, we recommend trauma teams approach LARI as they would an MVC., Competing Interests: Declaration of Competing Interest No., (Copyright © 2021 Elsevier Ltd.

Blunt thoracic aortic injury remains a major cause of prehospital deaths. For patients who reach the hospital alive, diagnosis and management have undergone dramatic changes over the last 50 years. Computed tomography scanning is the imaging modality of choice for injury diagnosis and repair planning. Medical management with antihypertensives dramatically decreases the risk of rupture, allowing for delayed repair, while abnormal physiology and more immediately life-threatening injuries can be addressed. Endovascular techniques and endograft technology have reduced significantly the risks associated with repair. However, the incidence of late complications associated with the devices currently available is not known., (Copyright © 2017 Elsevier Inc. All rights reserved.)
