RESUMO
Significant variations in the patterns of care, incidence, and mortality rates of several common cancers have been noted. These disparities have been attributed to a complex interplay of factors, including genetic, environmental, and healthcare-related components. Within this review, primarily focusing on commonly occurring cancers (breast, lung, colorectal), we initially summarize the burden of these disparities with regard to incidence and screening patterns. We then explore the interaction between several proven genetic, epigenetic, and environmental influences that are known to contribute to these disparities.

BACKGROUND: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is a major operation frequently necessitating red blood cell transfusion. Using multi-institutional data from the U.S. HIPEC Collaborative, this study sought to determine the association of perioperative allogenic blood transfusion (PABT) with perioperative outcomes after CRS/HIPEC. METHODS: This retrospective cohort study analyzed patients who underwent CRS/HIPEC for peritoneal surface malignancy between 2000 and 2017. Propensity score-matching was performed to mitigate bias. Univariate analysis was used to compare demographic, preoperative, intraoperative, and postoperative variables. Factors independently associated with PABT were identified using multivariate analysis. RESULTS: The inclusion criteria were met by 1717 patients, 510 (29.7%) of whom required PABT. The mean Peritoneal Cancer Index (PCI) of our cohort was 14.8 ± 9.3. Propensity score-matching showed an independent association between PABT and postoperative risk of pleural effusion, hemorrhage, pulmonary embolism, enteric fistula formation, Clavien-Dindo grades 3 and 4 morbidity, longer hospital stay, and reoperation (all P < 0.05 in the multivariate analysis). Compared with the patients who received 1 to 5 red blood cell (RBC) units, the patients who received more than 5 units had a greater risk of renal impairment, a longer intensive care unit (ICU) stay, and more postoperative infections. Finally, PABT was an independent predictor of worse survival for patients with appendiceal and colorectal primaries. CONCLUSION: Even low levels of PABT for patients undergoing CRS/HIPEC are independently associated with a greater risk of infectious and non-infectious postoperative complications, and this risk is increased for patients receiving more than 5 RBC units. Worse survival was independently predicted by PABT for patients with peritoneal carcinomatosis of an appendiceal or colorectal origin.

INTRODUCTION: The pediatric quality indicator (PDI) measures released by the Agency for Healthcare Research and Quality (AHRQ) provide an impetus for benchmarking quality of care in children. The PDI-17, aimed at studying perforation in appendicitis, is one such measure that this study aims to utilize to assess surgical care delivery and outcomes in children managed at majority-minority hospitals. METHODS: The Kid Inpatient Database (2000-2012) was queried for pediatric patients (< 18 years) with a diagnosis of appendicitis, with and without perforation. Facilities were categorized into tertiles based on rates of perforation (PDI-17). Similarly, tertiles were generated based on volume of minority patients (Black and Hispanic) treated at each facility. Multivariable regression analysis adjusted for demographic parameters, hospital-level characteristics, propensity score quintiles, clinically relevant outcomes, and tertiles of minority patients treated. RESULTS: Of the 322,805 patients with appendicitis 28.7% had perforated appendicitis. Patients presenting to facilities caring for a higher volume of perforated appendicitis were younger with public insurance or no insurance and, however, these patients were less likely to belong to a minority group (p < 0.05). Additionally, these patients were less likely to belong to the highest income quartile (OR [95% CI] 0.45 [0.39-0.52]). Hospitals treating the highest volume of minority patients [majority-minority hospitals (MMHs)] had an 87% (OR [95% CI] 1.87 [1.77-1.98]) increased likelihood of also treating the highest rates of perforated appendicitis. CONCLUSION: Hospitals treating a high volume of complicated appendicitis are less likely to care for minority groups. Additionally, MMHs lacking experience and volume in caring for complicated appendicitis have an increased likelihood of patients with perforations which is indicative of poor healthcare access.

INTRODUCTION: Non-accidental trauma (NAT) is one of the common causes of injury in children in the United States (US). Abuse and maltreatment affect 2 per 100,000 children annually and may go unrecognized. The aim of this study to quantify the recidivistic nature of NAT in the US pediatric population. METHODS: The National Readmissions Database (2007-2015) was queried for pediatric (≤18y) trauma patients. Children presenting for non-accidental trauma were further identified. Data was obtained on demographic, clinical, and hospital-level characteristics. Body regions with an Abbreviated Injury Scale (AIS) greater than three were further identified. Multivariable logistic regression analysis (adjusting for age, gender, insurance status, year, Injury Severity Score [ISS], hospital region, and mechanism of injury) was utilized to determine factors influencing unintentional and intentional (assault) non-accidental traumatic injuries. RESULTS: NAT represents 1.6% (n = 4,634/286,508) of all pediatric trauma. The median age of presentation was <1y [IQR:0-3] with a male predominance (56.2%). Median ISS was 9 [IQR:2-16]. 87.5% of incidents represented assault (intentional). The most commonly affected body region was the head and neck (32.8%), followed by the extremities (11.4%) and soft tissue trauma or burns (6.3%). Penetrating trauma accounted for 18% of these injuries. 3.2% were readmitted to the hospital for a recurrent episode. 85.5% presented to the hospital for their initial evaluation. Mortality rates were 3.8% for those re-admitted to the hospital. The most common perpetrators were other specified persons known to the family, followed by fathers and mothers. CONCLUSION: Although uncommon, recidivism, after an initial episode of NAT, can have devastating consequences. The majority of the perpetrators of abuse are individuals known to the patient or family. Health policy aimed towards developing preventative strategies is needed to facilitate early recognition and tackle abuse in children. LEVEL OF EVIDENCE: III. TYPE OF EVIDENCE: Case Control Study.

INTRODUCTION: Non-accidental trauma (NAT) affects 2 per 100,000 children annually in the US and may go unrecognized. The aim of this study to quantify the burden of NAT and to evaluate regional variations in mortality. METHODS: The Kids Inpatient Database (2000-2012) was queried for pediatric patients presenting with a diagnosis of NAT. Data was obtained on demographic, clinical and hospital-level characteristics. Primary outcome measure was mortality. Multivariable logistic regression models for age, sex, race/ethnicity, insurance status, income quartile, hospital volume, region (Northeast, South, West and Midwest), teaching status, and injury severity scores. RESULTS: NAT represented 1.92% (n = 15,999) of all trauma patients. Mortality rates were 3.98% for patients presenting with NAT. African American children had a higher likelihood of mortality compared to White children (OR[95%CI]:1.35[1.03-1.79]), however, this effect was not statistically significant for patients being treated at designated children's hospitals (OR[95%CI]:1.23(0.78-1.95) and urban facilities (OR[95%CI]:1.30[0.99-1.72]). Statistically significant regional variations in mortality, lost significance for patients treated at designated children's hospitals (p > 0.05). CONCLUSION: NAT has devastating consequences and is associated with a high mortality rate. Treatment at designated children's hospitals results in the loss of variation in mortality, resulting in diminished disparities and improved outcomes. These findings align with current trends towards the "regionalization of pediatric health care" and reflects the value of regional transfer centers that are.

BACKGROUND: Tumor markers are commonly utilized in the diagnostic evaluation, treatment decision making, and surveillance of appendiceal tumors. In this study, we aimed to determine the prognostic significance of elevated preoperative tumor markers in patients with pseudomyxoma peritonei secondary to low-grade appendiceal mucinous neoplasm who underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. METHODS: Using a multi-institutional database, eligible patients with measured preoperative tumor markers [carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA 19-9), or cancer antigen 125 (CA-125)] were identified. Univariate and multivariate Cox-proportional hazards regression analysis assessed relationships between normal and elevated serum tumor markers with progression-free and overall survival in the context of multiple clinicopathologic variables. RESULTS: zTwo hundred and sixty-four patients met criteria. CEA was the most commonly measured tumor marker (97%). Patients who had any elevated tumor marker had a higher peritoneal carcinomatosis index (PCI) as compared to those with normal range markers. Elevated CEA and CA 19-9 levels were individually associated with longer inpatient length of stay, requirement for intraoperative transfusion, and incomplete cytoreduction. Utilization of neoadjuvant chemotherapy, increased PCI score, elevated CA 19-9 (p = 0.007), and CA-125 levels (p = 0.01) were predictive of decreased progression-free survival on univariate analysis. However, in a multivariate model, only elevated PCI was a statistically significant predictor of progression-free survival. CONCLUSION: Elevated preoperative tumor markers indicate a higher burden of disease but are not independently associated with survival in this retrospective multi-institutional cohort. Further prospective studies are needed to clarify the utility of these markers in this patient population.

RESUMO
As the US healthcare system restructured to deal with the COVID-19 pandemic, medical training was significantly disrupted. During the peak of the crisis, three surgical trainees in different stages of their residency shared their experiences and concerns on how this pandemic affected their training. The article is intended to generate discussion on the concerns of derailment and stagnation of surgical training and difficulties faced at all levels of surgical training to perform clinical duties and fulfill academic responsibilities during the early months of the COVID pandemic.

RESUMO
INTRODUCTION: Trauma center care and survival have been improving over the past several years. However, yearly firearm-related deaths have remained near constant at 33 000. One challenge to decreasing gunshot mortality is patients presenting with complex injury patterns from multiple gunshot wounds (GSWs) made possible by high-caliber automated weapons. Our study analyzes outcomes of trauma patients of firearms using the National Trauma Databank (NTDB). METHODS: We conducted a retrospective review of the NTDB from the years 2003-2015 for patients with penetrating injuries. We separated patients into groups based on stab wounds, single GSW, and multiple GSW. We performed multivariate logistic regression analyses in which we adjusted for demographics and injury severity. RESULTS: Overall, 382 376 patients presenting with penetrating injuries were analyzed. Of those 167 671 had stab, 106 538 single GSW, and 57 819 multiple GSW injuries. Crude mortality was 1.97% for stab wounds, 13.26% for single GSW, and 18.84% for multiple GSW. Adjusted odds ratio (OR) compared with 2003 demonstrates a trend toward decreased mortality for stab wounds (OR range of 0.48-0.69, P < .05 for years 2010-2015). A similar trend was demonstrated in single GSW injuries (OR 0.31-0.83, P < .01 for years 2005-2015). Conversely, multiple GSW injuries did not follow this trend (OR 0.91-1.36 with P > 0.05 for each year). CONCLUSION: In contrast to significant improvement in survival in patients with a single GSW injury since 2003, multiple GSW injuries still pose a challenge to trauma care. This warrants further investigation into the efficacy of legislature, and the lack thereof, as well as future preventative measures to this type of injury.

The ability to differentiate between benign, suspicious, and malignant pulmonary nodules is imperative for definitive intervention in patients with early stage lung cancers. Here, we report that plasma protein functional effector sncRNAs (pfeRNAs) serve as non-invasive biomarkers for determining both the existence and the nature of pulmonary nodules in a three-stage study that included the healthy group, patients with benign pulmonary nodules, patients with suspicious nodules, and patients with malignant nodules. Following the standards required for a clinical laboratory improvement amendments (CLIA)-compliant laboratory-developed test (LDT), we identified a pfeRNA classifier containing 8 pfeRNAs in 108 biospecimens from 60 patients by sncRNA deep sequencing, deduced prediction rules using a separate training cohort of 198 plasma specimens, and then applied the prediction rules to another 230 plasma specimens in an independent validation cohort. The pfeRNA classifier could (1) differentiate patients with or without pulmonary nodules with an average sensitivity and specificity of 96.2% and 97.35% and (2) differentiate malignant versus benign pulmonary nodules with an average sensitivity and specificity of 77.1% and 74.25%. Our biomarkers are cost-effective, non-invasive, sensitive, and specific, and the qPCR-based method provides the possibility for automatic testing of robotic applications.
RESUMO
PURPOSE: Primary lymphedema presenting in adolescence is known as lymphedema praecox. Older children presenting with leg swelling are often subjected to a myriad of diagnostic tests. The purpose of this study is to review a large-cohort of patients with lymphedema praecox to determine the fiscal impact of diagnostic testing on these patients. METHODS: A 13-year review was performed of patients with lymphedema praecox. Information was obtained on demographic parameters, diagnostic studies performed, and clinical outcomes. RESULTS: Forty-nine patients were identified. The median age was 14 (range: 7-21) years. Participants were predominantly female (nâ¯=â¯40, 81.6%). 19 patients had bilateral disease and 30 had unilateral disease. The diagnosis was made on clinical exam only in 14 patients. 35 patients had imaging which consisted of plain X rays, Doppler ultrasound (DUS), lymphoscintigraphy (LSG) or MRI as the sole imaging study (nâ¯=â¯28) or in combination with others (nâ¯=â¯7). The charges for plain X-rays, DUS, LSG, and MRI with contrast were $335, $1715, $1269, and $6006 respectively. CONCLUSION: We believe that in the adolescent female with physical findings consistent with lymphedema praecox, diagnostic imaging should be limited to a Doppler ultrasound to rule out a secondary cause of the swelling. LEVEL OF EVIDENCE: IV TYPE OF EVIDENCE: Case series with no comparison group.

RESUMO
BACKGROUND: Cholecystectomy is the most commonly performed procedure in sickle cell disease (SCD) patients, but outcomes after cholecystectomy have not been well studied. Our aim was to explore the characteristics and outcomes of cholecystectomy in patients with SCD compared with patients without SCD, and assess whether acuity of presentation played a role. STUDY DESIGN: Patients younger than age 35, with the primary diagnosis of gallbladder disease, who underwent cholecystectomy, were identified in the Nationwide Inpatient Sample (2005 to 2014). Patients were grouped into treatment groups by sickle cell status and acuity of surgery. Patient demographics, length of stay, hospital charges, and complications were evaluated. Descriptive and multivariate regression analyses were performed to compare these groups. RESULTS: There were 149,415 patients analyzed; 1,225 (0.82%) had SCD. SCD was associated with higher complication rates (2.69% vs 1.12%), longer lengths of stay (3 days vs 2 days), and higher median hospital charge ($29,170 vs $25,438) (all p < 0.01). Stratified by level of acuity, comparing the SCD group with the non-SCD group, higher complication rates were seen in the acute presentation group (3.92% vs 1.00%, p < 0.01), but were not demonstrated in the elective group (0.98% vs 1.95%, p = 0.114). CONCLUSIONS: SCD patients appear to have a longer length of stay, higher hospital spending, and increased complication rates compared with non-SCD patients undergoing cholecystectomy. This difference is pronounced among patients who underwent surgery in the acute setting. The data suggest that planned cholecystectomy may be beneficial in improving postoperative outcomes in SCD patients.

INTRODUCTION: Trauma is the leading cause of mortality in children. Factors influencing recidivism after major trauma have not been well documented in children. The objective of this study is to determine the burden of pediatric trauma recidivism and to identify predisposing factors in the United States. METHODS: The 2010-2015 National Readmissions Database was queried for pediatric patients (≤18 years) with a diagnosis of major traumatic injuries. Patients readmitted for major trauma were subsequently identified. Patients that did not survive their index-hospitalization were excluded. Information on mechanism, intent, nature and injury severity including Abbreviated Injury Scale (AIS) and Injury Severity Scores (ISS) was obtained. Multivariable-regression analyses were performed adjusting for demographic, hospital-level and injury characteristics. RESULTS: Of 286,508 pediatric trauma records analyzed, trauma recidivists represented 2.9% of the total population. Recidivists had a higher proportion of severe (AISâ¯≥â¯3) head injury (11.3%). Recidivists were more likely to have public-insurance (OR [95% CI]:1.30[1.25-1.37]), and belong to lower income families (OR [95% CI]:1.22[1.15-1.31]). Recidivism was more common amongst patients with penetrating injuries (OR [95% CI]:2.12[1.96-2.28]). The risk adjusted cost of readmission for trauma was $8401[95% CI: 6748-10,053] higher compared to the index hospitalization with a total increased cost of 11.5 million USD annually. CONCLUSION: Although not common, recidivism after major trauma remains a significant public-health concern. This study gauges the previously unquantified burden of recidivism amongst children and identifies factors predisposing to recurrent trauma. LEVEL OF EVIDENCE: III TYPE OF EVIDENCE: Case control study.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the standard operative intervention for gallbladder disease. Complications may necessitate conversion to an open cholecystectomy (OC). This study aims to determine the cost-consequences of laparoscopic-to-open conversion using a nationally-representative sample. METHODS: Using the National Inpatient Sample (2007-2011), adult patients undergoing emergent LC were identified. Patients undergoing secondary-conversion to OC were subsequently identified. Multivariable regression analyses, accounting for differences in propensity-quintile, mortality, length of stay, and hospital-level factors were then performed to assess for differences in the odds of conversion and total predicted mean costs per index-hospitalization. RESULTS: Of 225,805 observations, conversion to open occurred in 1.86% (nâ¯=â¯4203) of cases. Increased age, African-American ethnicity, public-insurance and teaching-hospital status were associated with a higher likelihood of conversion (pâ¯<â¯0.05) after risk-adjustment. Risk-adjusted odds of conversion increased by 34% (95%CI:1.33-1.36) for each day surgery was delayed. Risk-adjusted costs, were 259% higher (absolute-difference $23,358,pâ¯<â¯0.05) with conversion. Mortality was higher amongst patients undergoing conversion to open (4.98% vs 0.34%,pâ¯<â¯0.001). CONCLUSION: Patients undergoing conversion from laparoscopic to open cholecystectomy are at an increased risk of receiving disparate care and increased mortality.

BACKGROUND AND OBJECTIVES: The use of laparoscopy in the trauma setting is gaining momentum, with more therapeutic procedures being performed. We evaluated the use of laparoscopic splenectomy among trauma patients with data from the National Trauma Database. We compared outcomes for trauma patients undergoing laparoscopic (LS) versus open splenectomy (OS). METHODS: From the National Trauma Database (2007 to 2015), we identified all patients who underwent a total splenectomy. Patients who had other abdominal operations were excluded. All patients were categorized into 1 of 2 groups: LS or OS. Outcomes of in-hospital mortality, postoperative length of stay, and incidence of major complications between the 2 groups were compared. Bivariate parametric and nonparametric analyses were performed. Patients were then matched on baseline demographic and injury characteristics by using propensity score matching techniques, and we compared differences by using regression analysis. RESULTS: A total of 25,408 patients underwent OS and 113 patients underwent LS (0.44%). Patients were significantly different at baseline, with the LS group being less severely injured. Bivariate analysis revealed no difference in length of stay (9 vs 8 days, P = .62), incidence of major complications (10% vs 15%, P = .24), or mortality (6% vs 11%, P = .23). LS was performed in 29.2% of patients beyond 24 hours from presentation compared with 9.5% in the OS (P < .001). Adjusted multivariate analysis showed no overall difference in outcomes. CONCLUSION: LS for trauma is increasingly being used at many centers throughout the United States. The procedure is safe, with outcomes similar to those of OS in selected trauma patients.
