RESUMO
OBJECTIVE: To determine if lymph node yield (LNY) is associated with improved overall survival (OS) and time to recurrence (TTR) in patients with node-negative pancreatic ductal adenocarcinoma (PDAC) treated with neoadjuvant therapy (NAT). BACKGROUND: Lymph node yield has been associated with survival in solid gastrointestinal cancers, including PDAC. METHODS: Patients with pathological T stage I-III, node-negative (N0), PDAC treated with NAT followed by pancreatoduodenectomy were identified in the Massachusetts General Hospital (MGH) pancreatectomy database and the National Cancer Database (NCDB). A cutoff point of 22 nodes was identified in the NCDB using the point with the optimal (log-rank test) split. Overall survival and TTR were evaluated using univariate and multivariable analyses. RESULTS: In the MGH cohort, 233 node-negative patients following NAT were included. A LNY ≥ 22 was associated with prolonged median OS (59 months vs. 25 months, P<0.001) and prolonged TTR (32 months vs. 14 months, P=0.019). On multivariable analysis, LNY was an independent predictor of survival (HR 0.97, 95% CI 0.95-0.99, P=0.034) per sampled node. In the NCDB, 2,029 node-negative patients following NAT were included. A LNY ≥ 22 was associated with prolonged median OS (49 months vs. 33 months, P<0.001). On multivariable analysis, LNY was an independent predictor of survival (HR 0.99, 95% CI 0.98-0.99, P<0.001) per sampled node. CONCLUSION: Lymph node yield was associated with improved oncologic outcomes in patients treated with NAT followed by pancreatoduodenectomy in two independent datasets. Responsible mechanisms by which LNY impacts the outcomes of node-negative patients following NAT warrant further exploration.
RESUMO
INTRODUCTION: Management of hemorrhage from pelvic fractures is complex and requires multidisciplinary attention. Pelvic angioembolization (AE) has become a key intervention to aid in obtaining definitive hemorrhage control. We hypothesized that pelvic AE would be associated with an increased risk of venous thromboembolism (VTE). METHODS: All adults (age >16) with a severe pelvic fracture (Abbreviated Injury Scale ≥ 4) secondary to a blunt traumatic mechanism in the 2017-2019 American College of Surgeons Trauma Quality Improvement Program database were included. Patients who did not receive VTE prophylaxis during their admission were excluded. Patients who underwent pelvic AE during the first 24 h of admission were compared to those who did not using propensity score matching. Matching was performed based on patient demographics, admission physiology, comorbidities, injury severity, associated injuries, other hemorrhage control procedures, and VTE prophylaxis type, and time to initiation of VTE prophylaxis. The rates of VTE (deep vein thrombosis and pulmonary embolism) were compared between the matched groups. RESULTS: Of 72,985 patients with a severe blunt pelvic fracture, 1887 (2.6%) underwent pelvic AE during the first 24 h of admission versus 71,098 (97.4%) who did not. Pelvic AE patients had a higher median Injury Severity Score and more often required other hemorrhage control procedures, with laparotomy being most common (24.7%). The median time to initiation of VTE prophylaxis in pelvic AE versus no pelvic AE patients was 60.1 h (interquartile range = 36.6-98.6) versus 27.7 h (interquartile range = 13.9-52.4), respectively. After propensity score matching, pelvic AE patients were more likely to develop VTE compared to no pelvic AE patients (11.8% versus 9.5%, P = 0.03). CONCLUSIONS: Pelvic AE for control of hemorrhage from severe pelvic fractures is associated with an increased risk of in-hospital VTE. Patients who undergo pelvic AE are especially high risk for VTE and should be started as early as safely possible on VTE prophylaxis.

BACKGROUND: Spontaneous retroperitoneal and rectus sheath hemorrhage (SRRSH) is associated with high mortality in the literature, but studies on the subject are lacking. The objective of this study was to identify early predictors of the need for angiographic or surgical intervention (ASI) in patients with SRRSH and define risk factors for mortality. METHODS: We conducted a retrospective cohort study at a tertiary academic hospital. All patients with computed tomography-identified SRRSH between 2012 to 2017 were included. Exclusion criteria were age below 18 years, possible mechanical cause of SRRSH, aortic aneurysm rupture or dissection, and traumatic or iatrogenic sources of SRRSH. The primary outcome was the incidence of ASI and/or mortality. RESULTS: Of 100 patients included (median age 70 years, 52% males), 33% were transferred from another hospital, 82% patients were on therapeutic anticoagulation, and 90% had serious comorbidities. Overall mortality was 22%, but SRRSH-related mortality was only 6%. Sixteen patients underwent angiographic intervention (n = 10), surgical intervention (n = 5), or both (n = 1). Flank pain (OR 4.15, 95% CI 1.21-14.16, p = 0.023) and intravenous contrast extravasation (OR 3.89, 95% CI 1.23-12.27, p = 0.020) were independent predictors of ASI. Transfer from another hospital (OR 3.72, 95% CI 1.30-10.70, p = 0.015), age above 70 years (OR 4.24, 95% CI 1.25-14.32, p = 0.020), and systolic blood pressure below 110 mmHg at the time of diagnosis (OR 4.59, 95% CI 1.19-17.68, p = 0.027) were independent predictors of mortality. CONCLUSIONS: SRRSH is associated with high mortality but is typically not the direct cause. Most SRRSHs are self-limited and require no intervention. Pattern identification of ASI is hard.

OBJECTIVE: Minimally invasive surgical necrosectomy and endoscopic necrosectomy, compared with open necrosectomy, might improve outcomes in necrotising pancreatitis, especially in critically ill patients. Evidence from large comparative studies is lacking. DESIGN: We combined original and newly collected data from 15 published and unpublished patient cohorts (51 hospitals; 8 countries) on pancreatic necrosectomy for necrotising pancreatitis. Death rates were compared in patients undergoing open necrosectomy versus minimally invasive surgical or endoscopic necrosectomy. To adjust for confounding and to study effect modification by clinical severity, we performed two types of analyses: logistic multivariable regression and propensity score matching with stratification according to predicted risk of death at baseline (low: <5%; intermediate: ≥5% to <15%; high: ≥15% to <35%; and very high: ≥35%). RESULTS: Among 1980 patients with necrotising pancreatitis, 1167 underwent open necrosectomy and 813 underwent minimally invasive surgical (n=467) or endoscopic (n=346) necrosectomy. There was a lower risk of death for minimally invasive surgical necrosectomy (OR, 0.53; 95% CI 0.34 to 0.84; p=0.006) and endoscopic necrosectomy (OR, 0.20; 95% CI 0.06 to 0.63; p=0.006). After propensity score matching with risk stratification, minimally invasive surgical necrosectomy remained associated with a lower risk of death than open necrosectomy in the very high-risk group (42/111 vs 59/111; risk ratio, 0.70; 95% CI 0.52 to 0.95; p=0.02). Endoscopic necrosectomy was associated with a lower risk of death than open necrosectomy in the high-risk group (3/40 vs 12/40; risk ratio, 0.27; 95% CI 0.08 to 0.88; p=0.03) and in the very high-risk group (12/57 vs 28/57; risk ratio, 0.43; 95% CI 0.24 to 0.77; p=0.005). CONCLUSION: In high-risk patients with necrotising pancreatitis, minimally invasive surgical and endoscopic necrosectomy are associated with reduced death rates compared with open necrosectomy.

BACKGROUND: The exact role of IV contrast-enhanced computed tomography (CT) in the diagnosis of necrotizing soft tissue infections (NSTIs) has not yet been established. We aimed to explore the role of CT in patients with clinical suspicion of NSTI and assess its sensitivity and specificity for NSTI. METHODS: The medical records of patients admitted between 2009 and 2016, who received IV contrast-enhanced CT to rule out NSTI, were reviewed. CT was considered positive in case of: (a) gas in soft tissues, (b) multiple fluid collections, (c) absence or heterogeneity of tissue enhancement by the IV contrast, and (d) significant inflammatory changes under the fascia. NSTI was confirmed only by the presence of necrotic tissue during surgical exploration. NSTI was considered absent if surgical exploration failed to identify necrosis, or if the patient was successfully treated non-operatively. RESULTS: Of the 184 patients, 17 had a positive CT and hence underwent surgical exploration with NSTI being confirmed in 13 of them (76%). Of the 167 patients that had a negative CT, 38 (23%) underwent surgical exploration due to the high clinical suspicion for NSTI and were all found to have non-necrotizing infections; the remaining 129 (77%) were managed non-operatively with successful resolution of symptoms. The sensitivity of CT in identifying NSTI was 100%, the specificity 98%, the positive predictive value 76%, and the negative predictive value 100%. CONCLUSIONS: A negative IV contrast-enhanced CT scan can reliably rule out the need for surgical intervention in patients with initial suspicion of NSTI.

BACKGROUND: Patients with gallstone pancreatitis (GP) or choledocholithiasis (CDL) may have common bile duct (CBD) stones that persist until cholangiography. The aim of this study is to evaluate pre-cholangiogram factors that predict persistent CBD stones. METHODS: Multiple logistic regression analyses were performed to identify demographic, laboratory, and radiologic predictors of persistent CBD stones and non-therapeutic cholangiography among adults with GP or CDL. RESULTS: In 152 patients from 2010 to 2015, preoperative diagnosis, presence of a CBD stone on US, and age ≥ 60 years were associated with persistent CBD stones. Two risk factors alone had a PPV of 88% and the absence of all risk factors had a NPV of 94%. Age < 60 years and the absence of a CBD stone on US were most predictive of non-therapeutic cholangiography. CONCLUSION: Age, LFTs, and US help predict persistent CBD stones in patients initially presenting with GP or CDL and help minimize non-therapeutic preoperative cholangiography.

OBJECTIVE: We sought to assess the impact of intraoperative adverse events (iAEs) on 30-day postoperative mortality, 30-day postoperative morbidity, and postoperative length of stay (LOS) among patients undergoing abdominal surgery. We hypothesized that iAEs would be associated with significant increases in each outcome. SUMMARY OF BACKGROUND DATA: The relationship between iAEs and postoperative clinical outcomes remains largely unknown. METHODS: The 2007 to 2012 institutional ACS-NSQIP and administrative databases for abdominal surgeries were matched then screened for iAEs using the Agency for Healthcare Research and Quality's 15 Patient Safety Indicator, "Accidental Puncture/Laceration". Each chart flagged during the initial screen was then manually reviewed to confirm whether an iAE occurred. Univariate then multivariable logistic regression models were constructed to assess the independent impact of iAEs on 30-day mortality, 30-day morbidity, and prolonged (≥7 days) postoperative LOS, controlling for preoperative/intraoperative variables (eg, age, comorbidities, ASA, wound classification), procedure type (eg, laparoscopic vs open, intestinal, foregut, hepatopancreaticobiliary vs abdominal wall procedure), and complexity (eg, adhesions; relative value units). Propensity score analyses were conducted with each iAE patient matched with 5 non-iAE patients. Sensitivity analyses were performed. RESULTS: A total of 9288 cases were included; 183 had iAEs. Most iAEs consisted of bowel (44%) or vessel (29%) injuries and were addressed intraoperatively (92%). In multivariable analyses, iAEs were independently associated with increased 30-day mortality [OR = 3.19, 95% confidence interval (CI) 1.52-6.71, P = 0.002], 30-day morbidity (OR = 2.68, 95% CI 1.89-3.81, P < 0.001), and prolonged postoperative LOS (OR = 1.85, 95% CI 1.27-2.70, P = 0.001). Postoperative complications associated with iAEs included deep/organ-space surgical site infection (OR = 1.94, 95% CI 1.20-3.14), P = 0.007), sepsis (OR = 2.14, 95% CI 1.32-3.47, P = 0.002), pneumonia (OR = 2.18, 95% CI 1.11-4.26, P = 0.023), and failure to wean ventilator (OR = 3.88, 95% CI 2.17-6.95, P < 0.001). Propensity score matching confirmed these findings, as did multiple sensitivity analyses. CONCLUSIONS: iAEs are independently associated with substantial increases in postoperative mortality, morbidity, and prolonged LOS. Quality improvement efforts should focus on iAE prevention, mitigation of harm after iAEs occur, and risk/severity-adjusted iAE tracking and benchmarking.

Enteric fistula is a serious complication of necrotizing pancreatitis. Endoscopic transluminal drainage and necrosectomy can significantly reduce the incidence of enterocutaneous fistula after pancreatic debridement. However, endoscopic necrosectomy may not be well-suited to debridement of necrosis that tracks laterally to the paracolic gutters, which is often more efficiently addressed by video-assisted retroperitoneal debridement (VARD). We report the combined use of endoscopic transgastric drainage and VARD for treatment of a 76 year old man with severe necrotizing acute pancreatitis complicated by infected, walled-off pancreatic necrosis. Computed tomography showed laterally tracking pancreatic necrosis and flouroscopic drain injection after percutaneous drainage demonstrated with fistulas to the stomach, duodenum, and colon. The infection and fistulas resolved completely. This approach combined the major advantage of VARD with the major advantage of endoscopic transluminal drainage. We are not aware of any reports of combining these techniques and believe the combination offers a minimally invasive approach for patients with extensive necrosis and a high likelihood of enteric or pancreatic fistulas.

BACKGROUND: Main concern during the practice of selective non-operative management (SNOM) for abdominal stab wounds (SW) and gunshot wounds (GSW) is the potential for harm in patients who fail SNOM and receive a delayed laparotomy (DL). The aim of this study is to determine whether such patients suffer adverse sequelae because of delays in diagnosis and treatment when managed under a structured SNOM protocol. METHODS: 190 patients underwent laparotomy after an abdominal GSW or SW (5/04-10/12). Patients taken to operation within 120 min of admission were included in the early laparotomy (EL) group (n =153, 80.5 %) and the remaining in the DL group (n =37, 19.5 %). Outcomes included mortality, hospital stay, and postoperative complications. RESULTS: The median time from hospital arrival to operation was 43 min (range: 17-119) for EL patients and 249 min (range: 122-1,545) for DL patients. The average number and type of injuries were similar among the groups. Mortality and negative laparotomy were observed only in the EL group. There was no significant difference in the hospital stay between the groups. The overall complications were higher in the EL group (44.4 vs. 24.3 %, p =0.026). DL was independently associated with a lower likelihood for complications (OR 0.39, 95 % CI 0.16-0.98, p =0.045). Individual review of all DL patients did not reveal an incident in which complications could be directly attributed to the delay. CONCLUSIONS: In a structured protocol, patients who fail SNOM and require an operation are recognized and treated promptly. The delay in operation does not cause unnecessary morbidity or mortality.

BACKGROUND: The value of additional imaging in clearing the cervical spine (C-spine) of alert trauma patients with tenderness on clinical exam and a negative computed tomographic (CT) scan is still unclear. METHODS: All adult trauma patients with a Glasgow Coma Scale of 15, C-spine tenderness in the absence of neurologic signs, and a negative C-spine CT were included. The study period extended from September 2011 to June 2012. C-spine CT scans were interpreted in detail and considered negative in the absence of any findings indicating bony, ligamentous, or soft tissue injury around the C-spine. The incidence of C-spine injury was evaluated using early (<24 h) repeat physical examination, MRI, and/or flexion-extension films. RESULTS: Of 2015 patients with a C-spine CT, 383 (19 %) fulfilled the inclusion criteria. The median age was 43 (IQR: 30-53) and 44.7 % were female. Thirty-six patients (9.4 %) underwent MRI (3.7 %), flexion-extension imaging (5.2 %), or both (0.5 %), with no significant injuries identified and subsequent removal of the collar allowed. The remaining patients were clinically cleared within 24 h of presentation. None of the patients developed neurological signs following removal of the collar. On bivariate analysis, no variable except for evaluation by trauma surgery was associated with performance of additional imaging. CONCLUSION: C-spine precautions can be withdrawn without additional imaging in most blunt trauma patients with C-spine tenderness but negative neurologic evaluation and C-spine CT. Focus should be placed on the detailed and comprehensive interpretation of the C-spine CT.

OBJECTIVE: To determine the role of intestinal alkaline phosphatase (IAP) in enteral starvation-induced gut barrier dysfunction and to study its therapeutic effect as a supplement to prevent gut-derived sepsis. BACKGROUND: Critically ill patients are at increased risk for systemic sepsis and, in some cases, multiorgan failure leading to death. Years ago, the gut was identified as a major source for this systemic sepsis syndrome. Previously, we have shown that IAP detoxifies bacterial toxins, prevents endotoxemia, and preserves intestinal microbiotal homeostasis. METHODS: WT and IAP-KO mice were used to examine gut barrier function and tight junction protein levels during 48-hour starvation and fed states. Human ileal fluid samples were collected from 20 patients postileostomy and IAP levels were compared between fasted and fed states. To study the effect of IAP supplementation on starvation-induced gut barrier dysfunction, WT mice were fasted for 48 hours +/- IAP supplementation in the drinking water. RESULTS: The loss of IAP expression is associated with decreased expression of intestinal junctional proteins and impaired barrier function. For the first time, we demonstrate that IAP expression is also decreased in humans who are deprived of enteral feeding. Finally, our data demonstrate that IAP supplementation reverses the gut barrier dysfunction and tight junction protein losses due to a lack of enteral feeding. CONCLUSIONS: IAP is a major regulator of gut mucosal permeability and is able to ameliorate starvation-induced gut barrier dysfunction. Enteral IAP supplementation may represent a novel approach to maintain bowel integrity in critically ill patients.

BACKGROUND: Pancreaticoduodenectomy for trauma (PDT) is a rare procedure, reserved for severe pancreaticoduodenal injuries. Using the National Trauma Data Bank (NTDB), our aim was to compare outcomes of PDT patients to similarly injured patients who did not undergo a PDT. METHODS: Patients with pancreatic or duodenal injuries treated with PDT (ICD-9-CM 52.7) were identified in the NTDB 20082010 Research Data Sets. We excluded those who underwent delayed PDT (>4 days). The PDT group (n = 39) was compared to patients with severe combined pancreaticoduodenal injuries (grade 4 or 5) who did not undergo PDT (non-PDT group, n = 38). Patients who died in the emergency department or did not undergo a laparotomy were excluded. Our primary outcome was death. Secondary outcomes were intensive care unit length of stay (LOS), hospital LOS, and total ventilator days. A multivariate model was used to determine predictors of in-hospital mortality within each group and in the overall cohort. RESULTS: The non-PDT group had a significantly lower systolic blood pressure and Glasgow Coma Scale values at baseline and more severe duodenal, pancreatic, and liver injuries. There were no significant differences in outcomes between the two groups. The Injury Severity Score was the only independent predictor of mortality among PDT patients [odds ratio (OR) 1.12, 95 % confidence interval (CI) 1.011.24] and in the entire cohort (OR 1.06, 95 % CI 1.011.12). The operative technique did not influence any of the outcomes. CONCLUSIONS: Compared to non-PDT, PDT did not result in improved outcomes despite a lower physiologic burden among PDT patients. More conservative procedures for high-grade injuries of the pancreaticoduodenal complex may be appropriate.

BACKGROUND: While cryoprecipitate (Cryo) is commonly included in massive transfusion protocols for hemorrhagic shock, the optimal dose of Cryo transfusion remains unknown. We evaluated the optimal red blood cell (RBC) to RBC to Cryo ratio during resuscitation in massively transfused trauma patients. METHODS: Adult patients in the American College of Surgeon Trauma Quality Improvement Program (2013-2019) receiving massive transfusion (≥4 U of RBCs, ≥1 U of fresh frozen plasma, and ≥1 U of platelets within 4 hours) were included. A unit of Cryo was defined as a pooled unit of 100 mL. The RBC:Cryo ratio was calculated for blood products transfused within 4 hours of presentation. The association between RBC:Cryo and 24-hour mortality was analyzed with multivariable logistic regression adjusting for the volume of RBC, plasma and platelet transfusions, global and regional injury severity, and other relevant variables. RESULTS: The study cohort included 12,916 patients. Among those who received Cryo (n = 5,511 [42.7%]), the median RBC and Cryo transfusion volume within 4 hours was 11 U (interquartile range, 7-19 U) and 2 U (interquartile range, 1-3 U), respectively. Compared with no Cryo administration, only RBC:Cryo ratios ≤8:1 were associated with a significant survival benefit, while lower doses of Cryo (RBC:Cryo >8:1) were not associated with decreased 24-hour mortality. Compared with the maximum dose of Cryo administration (RBC:Cryo, 1:1-2:1), there was no difference in 24-hour mortality up to RBC:Cryo of 7:1 to 8:1, whereas lower doses of Cryo (RBC:Cryo, >8:1) were associated with significantly increased 24-hour mortality. CONCLUSION: One pooled unit of Cryo (100 mL) per 7 to 8 U of RBCs could be the optimal dose of Cryo in trauma resuscitation that provides a significant survival benefit while avoiding unnecessary blood product transfusions. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level IV.

BACKGROUND: Data suggest that prolonged Emergency Department length of stay (EDLOS) has a detrimental effect on outcomes in some critically ill patients. However, the relationship between EDLOS and outcomes in traumatic brain injury (TBI) has not been examined. OBJECTIVE: Our objective was to determine the effect of EDLOS on neurologic outcomes in TBI patients. METHODS: We performed a retrospective analysis of a prospectively identified cohort of patients with moderate (Glasgow Coma Scale [GCS] score 9-13) and severe (GCS ≤ 8) TBI who presented to a Level 1 trauma center (2006-2010). Inclusion criteria were transfer to the intensive care unit (ICU) or operating room (OR) from the ED. Primary outcome was Glasgow Outcome Scale (GOS) score, a measure of neurologic function, at discharge. We used a proportional odds model to control for significant predictors of GOS in univariate analysis. RESULTS: Two hundred and twenty-four patients were included in the analysis, 77 (34%) of which were transferred to the OR. Median EDLOS was 3.3 h and 81.2% of patients had a GOS score ≤3 (e.g., severe disability, vegetative, or deceased). In multivariable analyses, EDLOS was not associated with GOS score in either ICU bound (p = 0.57) or OR bound (p = 0.11) patients. Younger age, pupil reactivity, and absence of intubation were independent predictors of good outcomes in the ICU group. In OR patients, predictors of higher GOS score included presence of an epidural hemorrhage, absence of midline shift, and pupil reactivity. CONCLUSIONS: Our study demonstrates that EDLOS was not associated with poor outcomes in patients with moderate to severe TBI who required intensive care or early operative intervention in an academic Level 1 trauma center.

Importance: For decades, infected or symptomatic pancreatic necrosis was managed by open surgical necrosectomy, an approach that has now been largely supplanted by an array of techniques referred to as the step-up approach. Observations: This review describes the evidence base behind the step-up approach, when to use the different techniques, and their technical basics. The most common treatment strategies are included: percutaneous drainage, video-assisted retroperitoneal debridement, sinus tract endoscopy, endoscopic transgastric necrosectomy, and surgical transgastric necrosectomy. Also included is the evidence base around management of common complications that can occur during step-up management, such as hemorrhage, intestinal fistula, and thrombosis, in addition to associated issues that can arise during step-up management, such as the need for cholecystectomy and disconnected pancreatic duct syndrome. Conclusions and Relevance: The treatment strategies highlighted in this review are those most commonly used during step-up management, and this review is designed as a guide to the evidence base underlying these strategies, as surgeons tailor their therapeutic approach to individual patients.

BACKGROUND: Abdominal wall hernias represent a common problem that can present as surgical emergencies with increased morbidity and mortality. The data examining outcomes in elderly patients with hernia emergencies is scant. METHODS: The 2007-2017 ACS-NSQIP database was queried. Patients ≥65 years old with a diagnosis of acute complicated abdominal wall hernia were included. Univariable and multivariable analyses were used to identify independent predictors of 30-day mortality and surgical site infection (SSI). RESULTS: Main predictors of 30-day mortality were admission from nursing home or chronic care facility (OR = 1.62, 95% CI: 1.10-2.38, P = .014), transfer from outside ED (OR = 1.81, 95% CI: 1.31-2.51, P < .001), days from admission to operation (OR = 1.05, 95% CI: 1.02-1.08, P = .002), recent significant weight loss (OR = 1.95, 95% CI: 1.12-3.37, P = .018), pre-operative septic shock (OR = 4.13, 95% CI: 2.44-6.99, P < .001), ventilator dependence (OR = 2.50, 95% CI: 1.29-4.81, P = .006), and ASA status. When compared to open repair, laparoscopic repair emerged as protective against SSI (OR = .34, 95% CI: .17-.66, P = .001). Bowel resection (OR = 2.15, 95% CI: 1.63-2.84, P < .001) and increasing wound class were risk factors for SSI. CONCLUSION: In the elderly patient presenting with an acute complicated abdominal wall hernia, time to surgery is crucial for survival, and comorbidities influence outcome. Laparoscopy is an option in management due to its decreased risk of surgical site infection without increased mortality, whenever patient factors are favorable for this approach.
