Factors Contributing to Patient Satisfaction Among VA Medical Center and Non-VA Medical Center Hospitals.

INTRODUCTION: Veteran satisfaction of care within the Veterans Affairs is typically very high. Yet recommendation ratings of VA medical center (VA) hospitals as measured by Hospital Consumer Assessment of Healthcare Providers and Systems are generally lower than non-VA hospitals.Therefore, it was our objective to assess Veteran satisfaction and recommendation scores and then examine whether satisfaction correlates to recommendation. METHODS: We identified all acute care VAs as our primary analytic cohort. As a comparator group, we also included all acute care academic hospitals (non-VAs), as designated by the Centers for Medicare Services. Using data from Hospital Consumer Assessment of Healthcare Providers and Systems and Strategic Analytics for Improvement and Learning (SAIL) Value Model, we collated patient satisfaction scores, as well as markers of surgical safety from Hospital Compare. We then analyzed the correlation within VAs and non-VAs, primarily focusing the relationship between the "would you recommend Hospital Rating" and subdomains of the "Overall Hospital Rating," as well as a composite score of patient safety. RESULTS: A total of 133 VAs and 1116 non-VAs were identified. Among VAs, the "Would you Recommend" hospital rating was significantly and positively correlated with markers of patient satisfaction including care transitions (Pearson's r = 0.59, P = 0.03), Nursing communication (Pearson's R 0.79, P = 0.001), and percent of primary care provider wait times less than 30 min (Pearson's r = 0.25, P = 0.01). VA-recommended scores were negatively correlated with factors such as time to emergency department discharge, and the "leaving the emergency department before being evaluated." When looking at non-VAs, correlation directions were similar, albeit with stronger associations at almost every metric. While recommended scores correlated strongly to overall hospital ratings for both groups, VAs had no significant correlation between "would you recommend" and patient safety. However, there was a slight negative correlation between patient safety and "recommend" among non-VAs. CONCLUSIONS: Although satisfiers and dissatisfiers of care appear similar between VAs and non-VAs, "would you recommend" is a far weaker marker of patient perceptions of safety and quality. These seemingly empathetic markers such as "would you recommend" should be used with caution as they may not address the fundamental question being asked.

A Retrospective Analysis of Surgical Acuity & Procedure Volume Before & During the COVID-19 Pandemic.

INTRODUCTION: In March 2020, the American College of Surgeons recommended postponing elective procedures amid the COVID-19 pandemic. We used Medicare claims to analyze changes in surgical and interventional procedure volumes from 2016 to 2021. METHODS: We studied 37 common surgical and interventional procedures using 5% Medicare claims files from January 1, 2016, through December 31, 2021. Procedures were classified according to American College of Surgeons guidelines as low, intermediate, or high acuity, and counts were analyzed per calendar year quarter (Q1-Q4), with stratification by sex and race/ethnicity. RESULTS: We observed 1,840,577 procedures and identified two periods of marked decline. In Q2 2020, overall procedure counts decreased by 32.2%, with larger declines in low (41.1%) and intermediate (30.8%) acuity procedures. High acuity procedures declined the least (18.2%). Overall volumes increased afterward but never returned to baseline. Another marked decline occurred in Q4 2021, with all acuity levels having declined to a similar extent (40.1%, 44.2%, and 46.9% for low, intermediate, and high acuity, respectively). High and intermediate acuity procedures declined more in Q4 2021 than Q2 2020 (P = 0.002). Similar patterns were observed across sex and race/ethnicity strata. CONCLUSIONS: Two major procedural volume declines occurred between 2020 and 2022 during the COVID-19 pandemic in the United States. High acuity (life or limb threatening) procedures were least affected in the first decline (Q2 2020) but not spared in second decline (Q4 2021). Future efforts should prioritize preserving high-acuity access during times of stress.

Intraoperative imaging and management of common duct stones during subtotal cholecystectomy.

BACKGROUND: Subtotal cholecystectomy is advocated in patients with severe inflammation and distorted anatomy preventing safe removal of the entire gallbladder. Not well documented in this surgically complex population is the feasibility of intraoperative imaging and management of common bile duct (CBD) stones. We evaluated these operative maneuvers in our subtotal cholecystectomy patients. METHODS: We retrospectively reviewed all cholecystectomy cases from 2014 to 2023 at a single Veterans Affairs (VA) Medical Center using VASQIP (VA Surgical Quality Improvement Program), selecting subtotal cholecystectomy cases for detailed analysis. We reviewed operative reports, imaging and laboratory studies, and clinical notes to understand biliary imaging, stone management, complications, and late outcomes including retained stones (within 6 months), and recurrent stones (beyond 6 months). RESULTS: 419 laparoscopic (n = 406) and open (n = 13) cholecystectomies were performed, including 40 subtotal cholecystectomies (36 laparoscopic, 4 laparoscopic converted to open). Among these 40 patients IOC was attempted in 35 and completed in 26, with successful stone management in 11 (9 common bile duct exploration [CBDE], 2 intraoperative endoscopic retrograde cholangiopancreatography [ERCP]). In follow-up, 3 additional patients had CBD stones managed by ERCP, including 1 with a negative IOC and 2 without IOC. Thus, 14 (35%) of 40 patients had CBD stones. Of note, IOC permitted identification and oversewing or closure of the cystic duct in 32 patients. There were no major bile duct injuries and one cystic duct stump leak (2.5%) that resolved spontaneously. CONCLUSIONS: Subtotal cholecystectomy patients had a high incidence of bile duct stones, with most detected and managed intraoperatively with CBDE, making a strong argument for routine IOC and single-stage care. When intraoperative imaging is not possible, postoperative imaging should be considered. Routine imaging, biliary clearance, and cystic duct closure during subtotal cholecystectomy is feasible in most patients with low rates of retained stones and bile leaks.

Increased Preoperative Stress Test Utilization is Not Associated With Reduced Adverse Cardiac Events in Current US Surgical Practice.

OBJECTIVE: To measure the frequency of preoperative stress testing and its association with perioperative cardiac events. BACKGROUND: There is persistent variation in preoperative stress testing across the United States. It remains unclear whether more testing is associated with reduced perioperative cardiac events. METHODS: We used the Vizient Clinical Data Base to study patients who underwent 1 of 8 elective major surgical procedures (general, vascular, or oncologic) from 2015 to 2019. We grouped centers into quintiles by frequency of stress test use. We computed a modified revised cardiac risk index (mRCRI) score for included patients. Outcomes included in-hospital major adverse cardiac events (MACEs), myocardial infarction (MI), and cost, which we compared across quintiles of stress test use. RESULTS: We identified 185,612 patients from 133 centers. The mean age was 61.7 (±14.2) years, 47.5% were female, and 79.4% were White. Stress testing was performed in 9.2% of patients undergoing surgery, and varied from 1.7% at lowest quintile centers, to 22.5% at highest quintile centers, despite similar mRCRI comorbidity scores (mRCRI>1: 15.0% vs 15.8%; P =0.068). In-hospital MACE was less frequent among lowest versus highest quintile centers (8.2% vs 9.4%; P <0.001) despite a 13-fold difference in stress test use. Event rates were similar for MI (0.5% vs 0.5%; P =0.737). Mean added cost for stress testing per 1000 patients who underwent surgery was $26,996 at lowest quintile centers versus $357,300 at highest quintile centers. CONCLUSIONS: There is substantial variation in preoperative stress testing across the United States despite similar patient risk profiles. Increased testing was not associated with reduced perioperative MACE or MI. These data suggest that more selective stress testing may be an opportunity for cost savings through a reduction of unnecessary tests.

A common genetic variant in zinc transporter ZnT2 (Thr288Ser) is present in women with low milk volume and alters lysosome function and cell energetics.

Suboptimal lactation is a common, yet underappreciated cause for early cessation of breastfeeding. Molecular regulation of mammary gland function is critical to the process lactation; however, physiological factors underlying insufficient milk production are poorly understood. The zinc (Zn) transporter ZnT2 is critical for regulation of mammary gland development and maturation during puberty, lactation, and postlactation gland remodeling. Numerous genetic variants in the gene encoding ZnT2 (SLC30A2) are associated with low milk Zn concentration and result in severe Zn deficiency in exclusively breastfed infants. However, the functional impacts of genetic variation in ZnT2 on key mammary epithelial cell functions have not yet been systematically explored at the cellular level. Here we determined a common mutation in SLC30A2/ZnT2 substituting serine for threonine at amino acid 288 (Thr288Ser) was found in 20% of women producing low milk volume (n = 2/10) but was not identified in women producing normal volume. Exploration of cellular consequences in vitro using phosphomimetics showed the serine substitution promoted preferential phosphorylation of ZnT2, driving localization to the lysosome and increasing lysosome biogenesis and acidification. While the substitution did not initiate lysosome-mediated cell death, cellular ATP levels were significantly reduced. Our findings demonstrate the Thr288Ser mutation in SLC30A2/ZnT2 impairs critical functions of mammary epithelial cells and suggest a role for genetic variation in the regulation of milk production and lactation performance.

Inability to replete white adipose tissue during recovery phase of sepsis is associated with increased autophagy, apoptosis, and proteasome activity.

Adipose tissue is an important energy depot and endocrine organ, and the degree of adiposity impacts the host response to infection. However, little is known regarding the mechanisms by which white adipose tissue (WAT) is lost acutely and then restored after the resolution of sepsis. Therefore, the signaling pathways governing protein synthesis, autophagy, apoptosis, and the ubiquitin-proteasome were investigated to identify potential mechanisms mediating the acute (24 h) loss of WAT after cecal ligation and puncture as well as the failure to replenish WAT during recovery (day 10). While whole body fat mass was decreased equally in pair-fed control and septic mice at 5 days after cecal ligation and puncture, fat mass remained 35% lower in septic mice at day 10 During sepsis-recovery, protein synthesis in epididymal WAT was increased compared with control values, and this increase was associated with an elevation in eukaryotic translation initiation factor (eIF)2Bε but no change in mammalian target of rapamycin complex 1 activity (eIF4E-binding protein-1 or S6 kinase 1 phosphorylation). Protein breakdown was increased during sepsis-recovery, as evidenced by the elevation in ubiquitin-proteasome activity. Moreover, indexes of autophagy (light chain 3B-II, autophagy-related protein 5/12, and beclin) were increased during sepsis-recovery and associated with increased AMP-activated kinase-dependent Ser555-phosphorylated Unc-51-like autophagy activating kinase-1. Apoptosis was increased, as suggested by the increased cleavage of caspase-3 and poly(ADP-ribose) polymerase. These changes were associated with increased inflammasome activity (increased NLR family, pyrin domain containing 3; TMS1; and caspase-1 cleavage) and the endoplasmic reticulum stress response (increased eIF2α and activating transcription factor-4) and browning (uncoupling protein-1) in epididymal WAT. Our data suggest that WAT stores remain depleted during recovery from sepsis due to sustained inflammation and elevations in protein and cellular degradation, despite the increase in protein synthesis.

The 1990s and the Association for Academic Surgery.

This lecture reviews the progress of the Association for Academic Surgery during the 1990s, a decade of sweeping innovations in technology, communication, and biomedical sciences; a well as a decade of transition in the demographics of surgical trainees; and a decade of new and previously unimagined possibilities for new directions in academic surgical careers.

Immune and metabolic responses in early and late sepsis during mild dietary zinc restriction.

BACKGROUND: Mild dietary zinc (Zn) deficiency is widespread in human populations, but its influence on recovery after acute illness is poorly understood. In a mouse model of abdominal sepsis (cecal ligation puncture), systemic immune responses and liver metabolism were monitored in early (24 h) and late (5 d) phases, under control conditions and during mild dietary Zn restriction. METHODS: Mice were fed diets adequate or marginally deficient (ZM) in Zn (30 versus 10 mg zinc/kg diet) for 4 wk, before undergoing laparotomy alone (nonseptic control) or cecal ligation puncture (septic). RESULTS: Among nonseptic mice, the ZM state was not associated with differences in inflammation or metabolic responses. Among septic mice, mortality did not differ between the zinc adequate and ZM groups. In the early phase, the ZM state amplified increases in plasma interleukin (IL) 6, tumor necrosis factor alpha, and IL-10, while dampening the interferon gamma response. In the late phase, subtle but significant ZM-associated increases were observed in plasma IL-5 and interferon gamma levels and hepatic protein synthesis, the latter of which appeared to be mammalian target of rapamycin independent and was associated with increased hepatic tumor necrosis factor alpha messenger RNA content. CONCLUSIONS: Without increasing mortality, the ZM state is associated with a more disordered acute systemic inflammatory response and persistence or enhancement of acute phase responses within the liver parenchyma.

Subtype-specific accumulation of intracellular zinc pools is associated with the malignant phenotype in breast cancer.

BACKGROUND: Zinc (Zn) hyper-accumulates in breast tumors and malignant cell lines compared to normal mammary epithelium. The mechanisms responsible for Zn accumulation and the consequence of Zn dysregulation are poorly understood. METHODS: Microarrays were performed to assess differences in the expression of Zn transporters and metallothioneins (MTs) in human breast tumors and breast cancer cell lines. Real-time PCR and immunoblotting were employed to profile Zn transporter expression in representative luminal (T47D), basal (MDA-MB-231), and non-malignant (MCF10A) cell lines. Zn distribution in human tumors was assessed by X-ray fluorescence imaging. Zn distribution and content in cell lines was measured using FluoZin-3 imaging, and quantification and atomic absorption spectroscopy. Functional consequences of ZnT2 over-expression in MDA-MB-231 cells including invasion, proliferation, and cell cycle were measured using Boyden chambers, MTT assays, and flow cytometry, respectively. RESULTS: Gene expression profiling of human breast tumors and breast cancer cell lines identified subtype-specific dysregulation in the Zn transporting network. X-ray fluorescence imaging of breast tumor tissues revealed Zn hyper-accumulation at the margins of Luminal breast tumors while Zn was more evenly distributed within Basal tumors. While both T47D and MDA-MB-231 cells hyper-accumulated Zn relative to MCF10A cells, T47D cells accumulated 2.5-fold more Zn compared to MDA-MB-231 cells. FluoZin-3 imaging indicated that Zn was sequestered into numerous large vesicles in T47D cells, but was retained in the cytoplasm and found in fewer and larger, amorphous sub-cellular compartments in MDA-MB-231 cells. The differences in Zn localization mirrored the relative abundance of the Zn transporter ZnT2; T47D cells over-expressed ZnT2, whereas MDA-MB-231 cells did not express ZnT2 protein due to proteasomal degradation. To determine the functional relevance of the lack of ZnT2 in MDA-MB-231cells, cells were transfected to express ZnT2. ZnT2 over-expression led to Zn vesicularization, shifts in cell cycle, enhanced apoptosis, and reduced proliferation and invasion. CONCLUSIONS: This comprehensive analysis of the Zn transporting network in malignant breast tumors and cell lines illustrates that distinct subtype-specific dysregulation of Zn management may underlie phenotypic characteristics of breast cancers such as grade, invasiveness, metastatic potential, and response to therapy.

Cost-effective Decisions in Detecting Silent Common Bile Duct Gallstones During Laparoscopic Cholecystectomy.

OBJECTIVE: To evaluate the cost-effectiveness of routine intraoperative ultrasonography (IOUS), cholangiography (IOC), or expectant management without imaging (EM) for investigation of clinically silent common bile duct (CBD) stones during laparoscopic cholecystectomy. BACKGROUND: The optimal algorithm for the evaluation of clinically silent CBD stones during routine cholecystectomy is unclear. METHODS: A decision tree model of CBD exploration was developed to determine the optimal diagnostic approach based on preoperative probability of choledocholithiasis. The model was parameterized with meta-analyses of previously published studies. The primary outcome was incremental cost per quality-adjusted life year (QALY) gained from each diagnostic strategy. A secondary outcome was the percentage of missed stones. Costs were from the perspective of the third party payer and sensitivity analyses were performed on all model parameters. RESULTS: In the base case analysis with a prevalence of stones of 9%, IOUS was the optimal strategy, yielding more QALYs (0.9858 vs 0.9825) at a lower expected cost ($311 vs $574) than EM. IOC yielded more QALYs than EM in the base case (0.9854) but at a much higher cost ($1122). IOUS remained dominant as long as the preoperative probability of stones was above 3%; EM was the optimal strategy if the probability was less than 3%. The percentage of missed stones was 1.5% for IOUS, 1.8% for IOC and 9% for EM. CONCLUSIONS: In the detection and resultant management of CBD stones for the majority of patients undergoing laparoscopic cholecystectomy, IOUS is cost-effective relative to IOC and EM.

Oral omega-3 fatty acids promote resolution in chemical peritonitis.

BACKGROUND: Recent studies suggest that purified omega-3 fatty acids may attenuate acute inflammation and hasten the transition to healing. In this study, we tested the hypothesis that pretreatment with omega-3-rich fish oil (FO) would promote resolution of peritoneal inflammation through production of specific lipid mediators. METHODS: C57/BL6 mice were given a daily 200-µL oral gavage of saline (CTL) or FO (1.0-1.5 g/kg/d docosahexaenoic acid and 1.3-2.0 g/kg/d eicosapentaenoic acid) for 7 d before chemical peritonitis was induced with thioglycollate. Peritoneal lavage fluid was collected before induction and at days 2 and 4 after peritonitis onset. Prostaglandin E2 (PGE2), Leukotriene B4 (LTB4), Resolvin D1 (RvD1), and the composition of immune cell populations were examined in peritoneal lavage exudates. Cells harvested from the peritoneum were assessed for macrophage differentiation markers, phagocytosis, and lipopolysaccharide-induced cytokine secretion profiles (interleukin [IL]-6, IL-10, IL-1ß, TNFα). RESULTS: The ratio of RvD1 to pro-inflammatory PGE2 and LTB4 was increased in the peritoneal cavity of FO-supplemented animals. FO induced a decrease in the number of monocytes in the lavage fluid, with no change in the number of macrophages, neutrophils, or lymphocytes. Macrophage phagocytosis and M1/M2 messenger RNA markers were unchanged by FO with the exception of decreased PPARγ expression. FO increased ex vivo TNFα secretion after stimulation with lipopolysaccharide. CONCLUSIONS: Our findings provide evidence that nutraceutically relevant doses of FO supplements given before and during chemical peritonitis shift the balance of lipid mediators towards a proresolution, anti-inflammatory state without drastically altering the number or phenotype of local innate immune cell populations.

Exome Sequencing of SLC30A2 Identifies Novel Loss- and Gain-of-Function Variants Associated with Breast Cell Dysfunction.

The zinc (Zn) transporter ZnT2 (SLC30A2) is expressed in specialized secretory cells including breast, pancreas and prostate, and imports Zn into mitochondria and vesicles. Mutations in SLC30A2 substantially reduce milk Zn concentration ([Zn]) and cause severe Zn deficiency in exclusively breastfed infants. Recent studies show that ZnT2-null mice have low milk [Zn], in addition to profound defects in mammary gland function during lactation. Here, we used breast milk [Zn] to identify novel non-synonymous ZnT2 variants in a population of lactating women. We also asked whether specific variants induce disturbances in intracellular Zn management or cause cellular dysfunction in mammary epithelial cells. Healthy, breastfeeding women were stratified into quartiles by milk [Zn] and exonic sequencing of SLC30A2 was performed. We found that 36% of women tested carried non-synonymous ZnT2 variants, all of whom had milk Zn levels that were distinctly above or below those in women without variants. We identified 12 novel heterozygous variants. Two variants (D(103)E and T(288)S) were identified with high frequency (9 and 16%, respectively) and expression of T(288)S was associated with a known hallmark of breast dysfunction (elevated milk sodium/potassium ratio). Select variants (A(28)D, K(66)N, Q(71)H, D(103)E, A(105)P, Q(137)H, T(288)S and T(312)K) were characterized in vitro. Compared with wild-type ZnT2, these variants were inappropriately localized, and most resulted in either 'loss-of-function' or 'gain-of-function', and altered sub-cellular Zn pools, Zn secretion, and cell cycle check-points. Our study indicates that SLC30A2 variants are common in this population, dysregulate Zn management and can lead to breast cell dysfunction. This suggests that genetic variation in ZnT2 could be an important modifier of infant growth/development and reproductive health/disease. Importantly, milk [Zn] level may serve as a bio-reporter of breast function during lactation.

Prolactin receptor attenuation induces zinc pool redistribution through ZnT2 and decreases invasion in MDA-MB-453 breast cancer cells.

Prolactin receptor (PRL-R) activation regulates cell differentiation, proliferation, cell survival and motility of breast cells. Prolactin (PRL) and PRL-R over-expression are strongly implicated in breast cancer, particularly contributing to tumor growth and invasion in the more aggressive estrogen-receptor negative (ER-) disease. PRL-R antagonists have been suggested as potential therapeutic agents; however, mechanisms through which PRL-R antagonists exert their actions are not well-understood. Zinc (Zn) is a regulatory factor for over 10% of the proteome, regulating critical cell processes such as proliferation, cell signaling, transcription, apoptosis and autophagy. PRL-R signaling regulates Zn metabolism in breast cells. Herein we determined effects of PRL-R attenuation on cellular Zn metabolism and cell function in a model of ER-, PRL-R over-expressing breast cancer cells (MDA-MB-453). PRL-R attenuation post-transcriptionally increased ZnT2 abundance and redistributed intracellular Zn pools into lysosomes and mitochondria. ZnT2-mediated lysosomal Zn sequestration was associated with reduced matrix metalloproteinase 2 (MMP-2) activity and decreased invasion. ZnT2-mediated Zn accumulation in mitochondria was associated with increased mitochondrial oxidation. Our results suggest that PRL-R antagonism in PRL-R over-expressing breast cancer cells may reduce invasion through the redistribution of intracellular Zn pools critical for cellular function.

Emphysematous gastritis and gastric emphysema: similar radiographic findings, distinct clinical entities.

INTRODUCTION: Despite similar appearances on imaging studies, emphysematous gastritis (EG) and gastric emphysema (GE) are rare clinical entities encountered in surgical practices. The purpose of this review is to clarify the presentation, natural history, and optimal treatment strategies for these two disorders. METHODS: We conducted a comprehensive literature review for reported adult cases of EG and GE in MEDLINE. Two cases from our institution were also included. Patient with demographics, diagnostic and therapeutic data, and outcomes were compared between patients with EG and GE. RESULTS: A total of 75 cases were included for our review. The finding of intramural air in the stomach was often associated with portal vein gas, pneumatosis intestinalis, or pneumoperitoneum in both groups. Surgical removal of the stomach was performed in 23.1% of EG patients, but only one patient in the GE group. In the EG group, overall mortality (55%) appeared to be driven by sepsis and its complications, whereas in the GE group, mortality (29%) was attributable to comorbid conditions and the underlying illness. CONCLUSIONS: Prompt surgical intervention is more commonly indicated for severe EG and is directed at removal of the septic organ, while the primary indication for surgical intervention in GE is the uncertainty of the diagnosis.

Persistent and chronic opioid use after ambulatory surgery in US veterans (2011-2018).

BACKGROUND: Opioid use beyond the perioperative period is a recognized adverse outcome, primarily studied in inpatients after complex major surgeries. Our goals are to determine the risk after ambulatory surgery and identify risk factors associated with long-term opioid prescriptions. METHODS: Our ambulatory surgery cohort included 1,393,332 veterans from October 1, 2011, to September 30, 2018 (fiscal year [FY] 12-18). Data included age, sex, race, rurality of patient residence and facility, body mass index, tobacco use, Charlson Comorbidity Index, psychiatric disorder, pain score at surgery, substance use, and medications (benzodiazepine, tricyclics and/or selective serotonin reuptake inhibitor and opioids in the 12 months previous). RESULTS: In aggregate, 9.6% had 1 or more prescriptions in the 90-180 days after surgery ("Persistent prescription[s]") and 1.8% had more than 180 days of opioids in the 31-366 days after surgery ("Chronic prescriptions"). For persistent prescription(s), trends over time decreased from 12.5% in FY12 to 7.1% by FY18 (P < .001). Similarly chronic prescriptions decreased from 2.9% in FY12 to 0.8% in FY18 (P < .001). The strongest independent association for persistent and chronic prescriptions after ambulatory surgery was previous prescription opioids, with 2.8 times increased risk for persistent prescriptions (adjusted odds ratio, 2.8; 95% confidence interval, 2.8-2.9; P < .001) and 3.3 times increased risk for chronic opioid prescriptions (adjusted odds ratio, 3.3; 95% confidence interval, 3.2-3.4; P < .001). CONCLUSIONS: Rates of persistent and chronic opioid prescriptions after ambulatory surgery in the Veterans Health Administration are small and decreasing over time. Providers and patients should have informed discussions regarding risks of opioid postoperative pain management strategies.

Engaging the Poetic Perspective on Care of the Surgical Patient: Lessons from W.H. Auden's "Surgical Ward".

Attention has been brought to the importance of cultivating empathy, communication skills, reflective writing, and self-care in surgeons-in-training. Classical literature and poetry pertaining to themes of surgery, specifically sonnets, can be exemplary methods for cultivating such skills. "Surgical Ward" by W.H. Auden is such a sonnet. Here we suggest that working poems such as "Surgical Ward" can cultivate transferable skills for analysis of text, context and subtext, as well as providing a substrate for discussion of multiple perspectives. These skills can aid in the development of surgical decision-making to produce positive outcomes, yet also benefit self-reflection when mistakes are inevitably made.

Image-based assessment of sarcopenic obesity predicts mortality in major trauma.

BACKGROUND: Patients with obesity are also at risk for sarcopenia, which is difficult to recognize in this population. Our study examines whether sarcopenic-obesity (SO) is independently associated with mortality in trauma. METHODS: Using a retrospective database, we performed logistic regression analysis. . Admission CT scans were used to identify SO by calculating the visceral fat to skeletal muscle ratio >3.2. RESULTS: Of 883 patients, the prevalence of SO was 38% (333). Patients with SO were more likely to be male (79% versus 43%, p < 0.001), older (mean 66.5 years versus 46.3 years, p < 0.001), and less likely to have an injury severity score (ISS) ≥ 24 (43% versus 55%, p = 0.0003). Using multivariable logistic regression analysis, SO was independently associated with mortality (OR 2.8; 95% CI 1.6-4.8, p < 0.001). Causal mediation analysis found admission hyperglycemia as a mediator for mortality. CONCLUSIONS: Sarcopenic obesity is an independent predictor of mortality in major trauma.
