    ABSTRACT: Adjuvant treatment for early stage, estrogen receptor (ER) positive invasive breast cancer has been based on prognosticators such as menopausal status. The recurrence score (RS) from the 21-gene assay Oncotype DX (ODX) is predictive of a 10-y distant recurrence in this population but is rarely applied to premenopausal patients. The relationship between menopausal status and RS was evaluated. An institutional review board-approved retrospective review was conducted of invasive breast cancer patients with known RS. ODX eligibility was based on National Comprehensive Cancer Network guidelines or physician discretion. Perimenopausal women were classified as premenopausal for statistical analyses. Comparisons of menopausal status and RS were made using general linear regression model and the exact Wilcoxon rank-sum test. Menopausal status was available for 575 patients (142 premenopausal, 433 postmenopausal). Median age was 46 y for premenopausal and 62 y for postmenopausal. Median invasive tumor size was 1.5 cm for both cohorts. Mastectomy rate was higher in the premenopausal group (54.8%) than postmenopausal (42%; P = 0.0001). Premenopausal women had a higher local-regional recurrence rate (2.8% versus 0%; P = 0.0384) but distant recurrence and overall survival were not statistically different (P = 0.6808). Median ER H-score was lower in premenopausal (H-score = 270) than postmenopausal women (H-score = 280; P < 0.0001). Median RS was 16 for both premenopausal (range, 0-54) and postmenopausal (range, 0-63) women. Menopausal status as a categorical variable was not predictive of RS (P-value = 0.6780). Menopausal status has limited predictive power for distant recurrence. Therefore, menopausal status alone should not preclude performance of ODX in ER-positive, early stage breast cancer.

    ABSTRACT: Muscle loss is a sequela of severe burn and critical illness with bed rest contributing significantly to atrophy. We hypothesize that exercise will mitigate muscle loss after burn with bed rest. Male rats were assigned to sham ambulatory (S/A), burn ambulatory (B/A), sham hindlimb unloading (S/H), or burn hindlimb unloading (B/H). Rats received a 40% scald burn or sham and were ambulatory or placed in hindlimb unloading, a model of bed rest. Half from each group performed twice daily resistance climbing. Hindlimb isometric forces were measured on day 14. Soleus mass and muscle function were not affected by burn alone. Mass was significantly lower in hindlimb unloading (79 versus 139 mg, P < 0.001) and no exercise (103 versus 115 mg, P < 0.01). Exercise significantly increased soleus mass in B/H (86 versus 77 mg, P < 0.01). Hindlimb unloading significantly decreased muscle force in the twitch (12 versus 31 g, P < 0.001), tetanic (55 versus 148 g, P < 0.001), and specific tetanic measurements (12 versus 22 N/cm(2), P < 0.001). Effects of exercise on force depended on other factors. In B/H, exercise significantly increased twitch (14 versus 8 g, P < 0.05) and specific tetanic force (14 versus 7 N/cm(2), P < 0.01). Fatigue index was lower in ambulatory (55%) and exercise (52%) versus hindlimb (69%, P = 0.03) and no exercise (73%, P = 0.002). Hindlimb unloading is a significant factor in muscle atrophy. Exercise increased the soleus muscle mass, twitch, and specific force in this model. However, the fatigue index decreased with exercise in all groups. This suggests exercise contributes to functional muscle change in this model of disuse and critical illness. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: Laparoscopic cholecystectomy is one of the most common general surgical procedures performed. Conversion to an open procedure (CTO) is associated with increased morbidity and length of stay. Patients presenting with acute cholecystitis are at higher risk for CTO. Studies have attempted to examine risk factors for CTO in patients who undergo laparoscopic cholecystectomy for acute cholecystitis but are limited by small sample size. The aim of this study was to identify preoperative variables that predict higher risk for CTO in patients presenting with acute cholecystitis.

    ABSTRACT: Lipopolysaccharide/D-Galactosamine (LPS/GalN)-induced hepatic injury is an experimental model of fulminant hepatic failure in which tumor necrosis factor-a (TNF-α) plays a pivotal role. Moreover, it was reported from our laboratory that interleukin (IL)-17A enhanced production of TNF-α by the Kupffer cell.

    ABSTRACT: This study sought to determine significance of radiocolloid injection timing for sentinel node biopsy (SNB) after neoadjuvant chemotherapy (NAC). A retrospective comparison of intraoperative (IRCI) and preoperative (PRCI) radiocolloid injection for SNB was performed in breast cancer patients who had completed NAC. The sentinel node identification rate (SNIDR) was tested for noninferiority by a two-proportion z-test. The differences between clinical demographics, pathologic demographics, and SNIDR were evaluated by Fisher exact test. The difference in the number of sentinel nodes removed was analyzed by two-sample t-test. In the 6-y study period, 120 SNB were performed after NAC: 84 received PRCI and 36 received IRCI. The two groups were similar except there were fewer clinical T2 and more clinical T3 and T4 with IRCI (P = 0.0008). The SNIDR was 92.9% with PRCI and 80.6% with IRCI. By two-proportion z-test, IRCI was not "noninferior" (P = 0.5179). By Fisher exact test, the SNIDR of the two groups did not differ. The SNIDR differs only in patients who experience T downstaging (100% versus 80%, P = 0.0173). The mean number of lymph nodes removed was higher with IRCI: 3.38 versus 2.49 nodes (P = 0.0068). There were more positive SNB with IRCI: 32.1% versus 55.2%, (P = 0.0432). The incidence of nontherapeutic axillary dissection was similar between the two groups (3.6% for PRCI versus 5.6% for IRCI). IRCI for SNB after NAC may be inferior to PRCI. Published by Elsevier Inc.

    ABSTRACT: Kidney injury is common in hemorrhagic shock (HS). Kidney injury leads to a systemic increase in serum chemokines and cytokines and causes injuries to other vital organs. Our previous studies showed that vitamin C led to organ protection and inflammation inhibitory effects in rat models of HS via induction heme oxygenase-1 (HO-1). We also found that biliary tract external drainage (BTED) increased the expression levels of HO-1 in rat livers. We investigated roles of BTED in kidney injury and its relationship with the HO-1 pathway in HS in this research.

    ABSTRACT: Our previous study, consistent with others, demonstrated that administering an exogenous surfactant was a potential therapy for acute lung injury and acute respiratory distress syndrome. However, the underlying mechanisms remain largely unknown. In the present study, we investigated the effect of instilled porcine pulmonary surfactant (PPS) on rat inhalation injury model induced by smoke and the possible mechanism. Fifteen Sprague-Dawley rats were equally randomized to three groups as follows (n = 5 in each group): sham control group (C group), inhalation injury group (II group), and inhalation injury + PPS treatment group (PPS group). Lung tissues were assayed for wet/dry ratio, histologic, terminal dUTP nick-end labeling staining, and Western blotting examinations. The myeloperoxidase activity was tested in lung tissues as well. Bronchoalveolar lavage fluid was collected to determine the total protein concentrations, inflammatory cytokines, surfactant protein A (SP-A), and SP-D. Our present work exhibited that PPS had therapeutic effects on smoke inhalation injury reflected by significant increase of PaO2 values, improved edema status, decreased vascular permeability, amelioration of lung histopathology, and reduction of inflammatory response. In addition, PPS treatment could increase endogenous SP-A levels both in lung tissue and bronchoalveolar lavage fluid. Further correlation analysis showed that SP-A was negatively correlated with both myeloperoxidase activity and interleukin 8 levels. These results indicate that PPS can attenuate smoke-induced inhalation injury at least partly through stimulating production of endogenous SP-A and inhibiting the release of proinflammatory cytokines such as interleukin 8. The increasing production of endogenous SP-A may be due to the antioxidant effect of PPS, which contains no SP-A. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: Many general surgical residency programs lack a formal international component. We hypothesized that most surgery programs do not have international training or do not provide the information to prospective applicants regarding electives or programs in an easily accessible manner via Web-based resources. Individual general surgery program Web sites and the American College of Surgeons residency tool were used to identify 239 residencies. The homepages were examined for specific mention of international or global health programs. Ease of access was also considered. Global surgery specific pages or centers were noted. Programs were assessed for length of rotation, presence of research component, and mention of benefits to residents and respective institution. Of 239 programs, 24 (10%) mentioned international experiences on their home page and 42 (18%) contained information about global surgery. Of those with information available, 69% were easily accessible. Academic programs were more likely than independent programs to have information about international opportunities on their home page (13.7% versus 4.0%, P = 0.006) and more likely to have a dedicated program or pathway Web site (18.8% versus 2.0%, P < 0.0001). Half of the residencies with global surgery information did not have length of rotation available. Research was only mentioned by 29% of the Web sites. Benefits to high-income country residents were discussed more than benefits to low- and middle-income country residents (57% versus 17%). General surgery residency programs do not effectively communicate international opportunities for prospective residents through Web-based resources and should seriously consider integrating international options into their curriculum and better present them on department Web sites.

    ABSTRACT: Pediatric scald burns result in frequent emergency room visits and hospitalizations. We investigated whether cooking-related burns produce greater morbidity requiring more extensive care than noncooking burns. We performed a 6-y review at our free-standing children's hospital. Children aged <18 y admitted for accidental scald burns were included. Demographics, injury pattern, treatment, and outcome (contractures and/or limited mobility and nonhealing and/or infected wounds) data were analyzed comparing cooking versus noncooking burns. The Mann-Whitney U test, a chi-square test, and the negative binomial were used to compare continuous, categorical, and count data between groups. Bivariate analysis was performed to identify risk factors among patients with adverse outcomes. We identified 308 patients; 262 (85%) cooking and 46 (15%) noncooking burns. Most patients were African-American males, with public insurance, and a median age of 2 y. Cooking burns preferentially occurred over the head, neck, and upper body; noncooking burns were distributed over the lower body (P < 0.02). Median total body surface area was equal for both groups (P > 0.11). In subgroup analysis, semisolid and grease burns resulted in increased rates of wound contractures and/or limited mobility when compared with noncooking burns (P = 0.05 and P = 0.008, respectively). Patients with complications were more likely to have third degree burns and required more consults, longer hospitalization, and more surgical debridements and clinic visits. Most accidental scald burns occurred in young children during food preparation. Greater long-term morbidity was found in patients with semisolid and grease burns. This subset of children has a higher injury burden and requires extensive care in the acute and long-term setting. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: Older age is associated with high rates of morbidity and mortality after injury. Statewide studies suggest significantly injured patients aged ≥55 y are commonly undertriaged to lower level trauma centers (TCs) or nontrauma centers (NTCs). This study determines whether undertriage is a national phenomenon. Using the 2011 Nationwide Emergency Department Sample, significantly injured patients aged ≥55 y were identified by diagnosis and new injury severity score (NISS) ≥9. Undertriage was defined as definitive care anywhere other than level I or II TCs. Weighted descriptive analysis compared characteristics of patients by triage status. Multivariable logistic regression determined predictors of undertriage, controlling for hospital characteristics, injury severity, and comorbidities. Of 4,152,541 emergency department (ED) visits meeting inclusion criteria, 74.0% were treated at lower level TCs or NTCs. Patients at level I and II TCs more commonly had NISS ≥9 (22.2% versus 12.3%, P < 0.001), but among all patients with NISS ≥9, 61.3% were undertriaged to a lower level TC or a NTC. On multivariable logistic regression, factors independently associated with higher odds of being undertriaged were increasing age, female gender, and fall-related injuries. A subgroup analysis examined urban and suburban areas only where access to a TC is more likely and found that 55.8% of patients' age were undertriaged. There is substantial undertriage of patients aged ≥55 y nationwide. Over half of significantly injured older patients are not treated at level I or II TCs. The impact of undertriage should be determined to ensure older patients receive trauma care at the optimal site. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: The learning style preferences of general surgery residents have been previously reported; there is evidence that residents who prefer read/write learning styles perform better on the ABSITE. However, little is known regarding the learning style preferences of applicants to general surgery residency and their impact on educational outcomes. In this study, the preferred learning styles of surgical residency applicants were determined. We hypothesized that applicant rank data is associated with specific learning style preferences.

    ABSTRACT: A history of previous abdominal surgery (PAS) may increase the complexity of laparoscopic colorectal surgery. The aim of this study was to investigate the impact of PAS on the outcomes of laparoscopic colorectal resection for colorectal cancer. A total of 378 colorectal cancer patients (group A) with a history of PAS were 1:1 matched to 378 controls (group B) without PAS from our prospective laparoscopic colorectal surgery database. The two groups were matched for age, gender, body mass index, American Society of Anesthesiology score, tumor location, type of surgical procedure, and tumor stage. Patients in the two groups were well balanced with respect to baseline demographic and clinical characteristics. Group A was associated with significantly longer median operating time (220 versus 200 min; P = 0.002). Conversion rate in group A (63/378, 16.67%) was almost twice as high as that in group B (36/378, 9.55%; P = 0.004). Conversions caused by adhesion were more common in patients with a history of PAS (55.56% [35/63] versus 27.78% [10/36], P = 0.008). Postoperative recovery time, length of postoperative hospital stay, perioperative mortality and morbidity rate, lymph nodes harvested, circumferential resection margin positive rate, 3-y disease-free survival, and overall survival rate were not significantly different between the two groups. Laparoscopic colorectal surgery for colorectal cancer patients with PAS is time consuming, but the incidence of a successfully completed laparoscopic colorectal resection remains high, and the short- and long-term outcomes are not affected by PAS.

    ABSTRACT: Esophageal perforation is a rare complication of enteric instrumentation in neonates. Enteric tube placement in micro-preemies poses a particular hazard to the narrow lumen and thin wall of the developing esophagus. The complication may be difficult to recognize or misdiagnosed as esophageal atresia, and is associated with considerable mortality. Historically, management of this life-threatening iatrogenic disease was operative, but trends have shifted toward nonoperative treatment. Here, we review neonatal esophageal perforation at our own institution for management techniques, risk factors, and outcomes. Seven neonatal patients with esophageal perforation were identified and charts reviewed for demographics, comorbidities, etiology of perforation, diagnostic modalities, management decisions, complications, and outcomes. Mean gestational age was 27.2 ± 4.0 wk, and weight at diagnosis was 892 ± 674 g. All seven patients had esophageal perforation resulting from endotracheal or enterogastric intubation and were managed nonoperatively. Treatment included removal of the offending tube, nil per os, and antibiotics. Five patients required additional interventions: four tube thoracostomies for pneumothoraces and one peritoneal drain for pneumoperitoneum. Three patients died because of sequelae of prematurity (intraventricular hemorrhage, necrotizing enterocolitis, and sepsis). One patient was diagnosed as having esophageal atresia; esophagoscopy before surgical repair established the correct diagnosis. Neonates, particularly those under 1500 g, are at substantial risk for iatrogenic esophageal perforation during enterogastric intubation. Nonoperative management may be a safe initial strategy in the neonatal setting, but more aggressive interventions may ultimately be required. Despite recent improvement in early recognition of this injury, misdiagnosis still occurs. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: Use of the Trauma and Injury Severity Score (TRISS) for quality and outcomes assessment is challenged by the need for laborious collection of demographic and physiological data. We hypothesize that a novel stratification approach based on ICD-9 data that are readily available for trauma patients provides a more accurate and more easily obtainable alternative to TRISS with the potential for widespread use.

    ABSTRACT: The diagnosis of acute cholecystitis (AC) is challenging and may result in a delay in surgery, hospital discharge, and increased mortality. To improve its diagnosis, C-reactive protein (CRP) has been proposed as a benchmark. The aim of this study was to evaluate discriminative power of CRP against white cell count (WCC) in AC. This was a retrospective cohort study. Over a 5-y period, 1959 patients were identified from the audit of cholecystectomies. The exclusion criteria were coexisting acute surgical conditions, absence of blood tests within 3 d before hospital admission for elective surgery, and private patients. The eligibility criteria were met by 1843 patients. Comparison of the area under receiver operating characteristic (AUC) curve of CRP and WCC in acute on chronic, edematous, necrotic, suppurative, and gangrenous AC showed a better discriminative power of CRP. Both tests performed equally well in patients with pericholecystic abscess and gallbladder perforation. CRP was superior than WCC in mild AC, AUC = 0.93 (95% confidence interval [CI], 0.9-0.95) and 0.79 (95% CI, 0.74-0.84), P < 0.00005, in moderate and severe AC, AUC = 0.99 (95% CI, 0.97-1.0) and 0.92 (95% CI, 0.88-0.97), P = 0.009, and in all forms of AC combined, AUC = 0.94; (95% CI, 0.92-0.97) and 0.83 (95% CI, 0.79-0.87), respectively, P < 0.00005. CRP has a better discriminative power than WCC in most forms of AC and is a useful diagnostic marker of AC. Copyright © 2015 Elsevier Inc. All rights reserved.
