RESUMEN
BACKGROUND & AIMS: Next-generation sequencing (NGS) of pancreatic cyst fluid is a useful adjunct in the assessment of patients with pancreatic cyst. However, previous studies have been retrospective or single institutional experiences. The aim of this study was to prospectively evaluate NGS on a multi-institutional cohort of patients with pancreatic cyst in real time. METHODS: The performance of a 22-gene NGS panel (PancreaSeq) was first retrospectively confirmed and then within a 2-year timeframe, PancreaSeq testing was prospectively used to evaluate endoscopic ultrasound-guided fine-needle aspiration pancreatic cyst fluid from 31 institutions. PancreaSeq results were correlated with endoscopic ultrasound findings, ancillary studies, current pancreatic cyst guidelines, follow-up, and expanded testing (Oncomine) of postoperative specimens. RESULTS: Among 1933 PCs prospectively tested, 1887 (98%) specimens from 1832 patients were satisfactory for PancreaSeq testing. Follow-up was available for 1216 (66%) patients (median, 23 months). Based on 251 (21%) patients with surgical pathology, mitogen-activated protein kinase/GNAS mutations had 90% sensitivity and 100% specificity for a mucinous cyst (positive predictive value [PPV], 100%; negative predictive value [NPV], 77%). On exclusion of low-level variants, the combination of mitogen-activated protein kinase/GNAS and TP53/SMAD4/CTNNB1/mammalian target of rapamycin alterations had 88% sensitivity and 98% specificity for advanced neoplasia (PPV, 97%; NPV, 93%). Inclusion of cytopathologic evaluation to PancreaSeq testing improved the sensitivity to 93% and maintained a high specificity of 95% (PPV, 92%; NPV, 95%). In comparison, other modalities and current pancreatic cyst guidelines, such as the American Gastroenterology Association and International Association of Pancreatology/Fukuoka guidelines, show inferior diagnostic performance. The sensitivities and specificities of VHL and MEN1/loss of heterozygosity alterations were 71% and 100% for serous cystadenomas (PPV, 100%; NPV, 98%), and 68% and 98% for pancreatic neuroendocrine tumors (PPV, 85%; NPV, 95%), respectively. On follow-up, serous cystadenomas with TP53/TERT mutations exhibited interval growth, whereas pancreatic neuroendocrine tumors with loss of heterozygosity of ≥3 genes tended to have distant metastasis. None of the 965 patients who did not undergo surgery developed malignancy. Postoperative Oncomine testing identified mucinous cysts with BRAF fusions and ERBB2 amplification, and advanced neoplasia with CDKN2A alterations. CONCLUSIONS: PancreaSeq was not only sensitive and specific for various pancreatic cyst types and advanced neoplasia arising from mucinous cysts, but also reveals the diversity of genomic alterations seen in pancreatic cysts and their clinical significance.

OBJECTIVE: We report the development and validation of a combined DNA/RNA next-generation sequencing (NGS) platform to improve the evaluation of pancreatic cysts. BACKGROUND AND AIMS: Despite a multidisciplinary approach, pancreatic cyst classification, such as a cystic precursor neoplasm, and the detection of high-grade dysplasia and early adenocarcinoma (advanced neoplasia) can be challenging. NGS of preoperative pancreatic cyst fluid improves the clinical evaluation of pancreatic cysts, but the recent identification of novel genomic alterations necessitates the creation of a comprehensive panel and the development of a genomic classifier to integrate the complex molecular results. METHODS: An updated and unique 74-gene DNA/RNA-targeted NGS panel (PancreaSeq Genomic Classifier) was created to evaluate 5 classes of genomic alterations to include gene mutations (e.g., KRAS, GNAS, etc.), gene fusions and gene expression. Further, CEA mRNA ( CEACAM5 ) was integrated into the assay using RT-qPCR. Separate multi-institutional cohorts for training (n=108) and validation (n=77) were tested, and diagnostic performance was compared to clinical, imaging, cytopathologic, and guideline data. RESULTS: Upon creation of a genomic classifier system, PancreaSeq GC yielded a 95% sensitivity and 100% specificity for a cystic precursor neoplasm, and the sensitivity and specificity for advanced neoplasia were 82% and 100%, respectively. Associated symptoms, cyst size, duct dilatation, a mural nodule, increasing cyst size, and malignant cytopathology had lower sensitivities (41-59%) and lower specificities (56-96%) for advanced neoplasia. This test also increased the sensitivity of current pancreatic cyst guidelines (IAP/Fukuoka and AGA) by >10% and maintained their inherent specificity. CONCLUSIONS: PancreaSeq GC was not only accurate in predicting pancreatic cyst type and advanced neoplasia but also improved the sensitivity of current pancreatic cyst guidelines.

Orthotopic liver transplantation continues to be the only effective therapy for patients with end-stage liver disease. Unfortunately, many of these patients are not considered transplant candidates, lacking effective therapeutic options that would address both the irreversible progression of their hepatic failure and the control of their portal hypertension. In this prospective study, a swine model was exploited to induce subacute liver failure. Autologous hepatocytes, isolated from the left hepatic lobe, were transplanted into the mesenteric lymph nodes (LNs) by direct cell injection. At 30-60 days after transplantation, hepatocyte engraftment in LNs was successfully identified in all transplanted animals with the degree of ectopic liver mass detected being proportional to the induced native liver injury. These ectopic livers developed within the LNs showed remarkable histologic features of swine hepatic lobules, including the formation of sinusoids and bile ducts. On the basis of our previous tyrosinemic mouse model and the present pig models of induced subacute liver failure, the generation of auxiliary liver tissue using the LNs as hepatocyte engraftment sites represents a potential therapeutic approach to supplement declining hepatic function in the treatment of liver disease.

PURPOSE: The objective of the study is to investigate trajectories of stress and depressive symptoms of spousal and intimate partner caregivers in the context of cancer. We also examined the patient-related predictors of caregiver stress and depression. DESIGN: This is a longitudinal cohort study. PARTICIPANTS: Patients diagnosed with cancers affecting the hepatobiliary and pancreatic system and their spousal or intimate partner caregivers were recruited at a large tertiary cancer center. METHODS: The patients and caregivers were assessed for their level of stress, depressive symptoms, relationship quality, and quality of life at the time of the patients' diagnosis, every 2 months for 12 months and then at 18 months. FINDINGS: One hundred and seventy-nine caregivers were included in the trajectory analyses. Amongst the 179 caregivers, 120 patient and caregiver dyads had complete data at baseline to 6-months. The majority of the spousal caregivers were female (84%) and the mean age was 57 years. 25% of caregivers reported high levels of chronic depressive symptoms. However, significant reductions were observed at 6 months. High and moderate levels of caregiver stress were also reported in 21% and 36% of caregivers, respectively. The caregivers who reported moderate levels of stress had a decrease in stress over time while those in the high stress group reported stable levels of stress over time. Caregivers' stress is predicted by the cancer patients' depressive symptoms but not patients' quality of life. CONCLUSIONS: Caregivers who reported high levels of stress and depressive symptoms at patients' cancer diagnosis remain high even after the initial adjustment. A bidirectional relationship between the caregivers' stress and the patients' depressive symptoms was observed. IMPLICATIONS: The development of dyadic interventions focusing on the patients' and caregivers' distress is warranted to decrease psychological morbidities of the dyad.

OBJECTIVE: According to the Common-Sense Model of Self-Regulation, when faced with a health threat, we make cognitive and emotional assumptions about the illness. The aims of this study were to (a) examine the role of sociodemographic and disease-specific factors on illness perception and perceived stress and (b) test the association between perceived stress and illness perception in participants diagnosed with gastrointestinal cancer. METHODS: Participants completed a battery of questionnaires including a Sociodemographic and Disease-Specific Questionnaire, the Illness Perception Questionnaire, Brief Version (Brief-IPQ), and the Perceived Stress Scale (PSS-14). Descriptive statistics, Pearson correlations, analysis of variance (ANOVA), and linear regression were performed to test the hypotheses. RESULTS: Of the 627 participants, the mean age was 62 years (SD = 11); the majority were male (63.3%) and Caucasian (90.9%). Younger (F3,625 = 5.80, P < .01) and divorced or never married participants reported higher levels of perceived stress when compared with older and married participants (F4,618 = 3.52, P < .01). Younger participants (18-74 years old) reported more negative illness perceptions than older participants (75 years and older) (F3,511 = 4.08, P < .01). A weak, positive relationship between perceived stress and illness perceptions was observed (r = 0.22, P < .01), and illness perceptions predicted 36.1% of the variance of perceived stress. CONCLUSIONS: Our findings suggest that participants who negatively perceived their illness experienced greater levels of perceived stress. Interventions that aim to adjust patients' illness perceptions in order to facilitate a reduction of stress and improvement in quality of life are needed.

OBJECTIVE: Cancer caregivers are at increased risk for cardiovascular disease (CVD) and mortality. The aims of this study were to examine psychosocial and behavioral predictors of metabolic syndrome, an intermediate endpoint of CVD. METHODS: Cancer caregivers were administered a battery of questionnaires assessing sociodemographic characteristics, depressive symptoms, perceived stress, caregiver quality of life, sleep, physical activity, alcohol and tobacco use, social support, relationship quality, and loneliness. Metabolic syndrome was defined using the American Heart Association guidelines and the National Cholesterol Education Program's Adult Treatment Panel (ATP) III, which includes the presence of at least three of the following abnormalities: blood pressure, glucose, abdominal girth, high-density lipoprotein (HDL), and triglycerides. RESULTS: Of the 104 caregivers, 77% were female, 94% were Caucasian, and the mean age was 59.5 (SD = 12.8). Of the 104 caregivers, 35.6% reported depressive symptoms in the clinical range of the Center for Epidemiologic Studies-Depression (CES-D) and 69.2% reported Perceived Stress Scale scores at least one standard deviation above the general population norms. A total of 16.3% of caregivers currently used tobacco, 28.8% consumed alcohol, and 26.7% were overweight (BMI = 25-29.9) and 48.5% were obese (BMI ≥ 30). Forty-nine percent of the caregivers met the criteria for metabolic syndrome. After age, gender, and race were adjusted, the following remained as significant predictors of metabolic syndrome: low levels of caregiver quality of life (Odds Ratio (OR) = 1.067; 95% CI, 1.019-1.117; P = .006), high levels of hostility (OR = 1.142; 95% CI, 1.030-1.267; P = .012), and current alcohol use (OR = 4.193; 95% CI, 1.174-14.978; P = .027). CONCLUSION: Development of interventions to reduce the risk of metabolic syndrome in cancer caregivers is recommended.

BACKGROUND: The aim of this study was to examine predictors of health behaviors over time and the link between health behaviors and survival after a diagnosis of advanced cancer. METHODS: Patients with a diagnosis of advanced cancer were administered a battery of questionnaires measuring optimism, depressive symptoms, physical activity, intake of fruits and vegetables, and alcohol and tobacco use over an 18-month period. Analyses included generalized linear mixed models and Cox regression survival analyses. RESULTS: Of the 334 patients enrolled in the study, the mean age at cancer diagnosis was 62 years; the majority were male (62.3%) and white (91%). Twenty percent of the patients reported using alcohol, 19% reported using tobacco, 19% reported eating fewer fruits and vegetables than recommended by the Centers for Disease Control and Prevention and 28% reported physical inactivity after the diagnosis of advanced cancer. Clinical levels of depressive symptoms were associated with lower intake of fruits and vegetables (t = 2.67, P = .007) and physical inactivity (t = 2.11, P = .035). Dispositional optimism was positively associated with physical activity (t = -2.16, P = .031) and a lower frequency of tobacco use (Z = -2.42, P = .015). Multivariate analyses revealed that after adjusting for demographic variables (age and sex), depressive symptoms, and disease-specific factors (diagnosis, tumor size, cirrhosis, vascular invasion, and number of lesions), alcohol use (χ2 = 4.1186, P = .042) and physical inactivity (χ2 = 5.6050, P = .018) were linked to an poorer survival. CONCLUSIONS: Greater dissemination and implementation of effective interventions to reduce alcohol use and increase physical activity in cancer patients are recommended.

The rectal trumpet (RT) is a nasopharyngeal airway device that is inserted into the rectum for management of fecal incontinence. No published data exist on adverse events caused by the use of an RT. The purpose of this quality improvement project was to determine the rate of RT-associated hemorrhage among patients treated with an RT in our transplant intensive care unit (TICU). This quality improvement initiative and retrospective medical record review included all patients (N = 3933) cared for in a single specialty intensive care unit at a tertiary academic medical center between January 1, 2014, and May 31, 2016. We estimate that approximately 400 patients were treated with an RT. We found 3 possible and 9 probable cases of RT-associated hemorrhage, resulting in an estimated incident rate of 3% among RT-treated patients. All of these patients underwent invasive procedures for hemostasis. They received a mean of 4.9 units of packed red blood cell transfusions, and 9 experienced hypotension. Eight out of the 9 probable RT-associated hemorrhage patients experienced hemorrhage only after greater than 7 days of treatment with an RT. Following this initiative, RT use was banned in our TICU. The use of RTs can cause hemorrhage with clinically significant consequences.

BACKGROUND: The aim of this study was to examine the efficacy of a collaborative care intervention in reducing depression, pain, and fatigue and improve quality of life. METHODS: A total of 261 patients with advanced cancer and 179 family caregivers were randomized to a web-based collaborative care intervention or enhanced usual care. The intervention included the following: 1) a web site with written and audiovisual self-management strategies, a bulletin board, and other resources; 2) visits with a care coordinator during a physician's appointment every 2 months; and 3) telephone follow-up every 2 weeks. Primary patient outcomes included measures of depression, pain, fatigue, and health-related quality of life. Secondary outcomes included Interleukin (IL)-1α, IL-1ß, IL-6, and IL-8 levels, Natural Killer (NK) cell numbers, and caregiver stress and depression. RESULTS: At the baseline, 51% of the patients reported 1 or more symptoms in the clinical range. For patients who presented with clinical levels of symptoms and were randomized to the intervention, reductions in depression (Cohen's d = 0.71), pain (Cohen's d = 0.62), and fatigue (Cohen's d = 0.26) and improvements in quality of life (Cohen's d = 0.99) were observed when compared to those in the enhanced usual car arm at 6 months. Reductions in IL-6 (φ = 0.18), IL-1ß (φ = 0.35), IL-1α (φ = 0.19), and IL-8 (φ = 0.15) and increases in NK cell numbers (φ = 0.23) were observed in comparison with enhanced usual care arm at 6 months. Reductions in caregiver stress (Cohen's d = 0.75) and depression (Cohen's d = 0.37) were observed at 6 months for caregivers whose loved ones were randomized to the intervention arm. CONCLUSIONS: The integration of screening and symptom management into cancer care is recommended.

OBJECTIVE: To characterize clinical and radiological features associated with biliary cystic tumors (BCTs) of the liver, and to define recurrence-free and overall survival. BACKGROUND: Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC) are rare tumors that arise in the liver. METHODS: Between 1984 and 2013, 248 patients who underwent surgical resection of BCA or BCAC were identified. Clinical and outcome data were analyzed. RESULTS: Median total bilirubin, CA19-9, and carcinoembryonic antigen (CEA) levels were 0.6 mg/dL, 15.0 U/mL, and 2.7 ng/mL, respectively. Preoperative imaging included computed tomography only (62.5%), magnetic resonance imaging only (6.9%), or CT + MRI (18.5%). Features on cross-sectional imaging included multiloculation (56.9%), mural nodularity (16.5%), and biliary ductal dilatation (17.7%). The presence of these factors did not reliably predict BCAC versus BCA (sensitivity, 81%; specificity, 21%). Median biliary cyst size was 10.0 cm (interquartile range, 7-13 cm). Operative interventions included unroofing/partial excision of the lesion (14.1%), less than hemihepatectomy (48.8%), or hemi-/extended hepatectomy (36.3%). On pathology most lesions were BCA (89.1%), whereas 27 (10.9%) were BCAC. At last follow-up, there were 46 (18.3%) recurrences; 2 patients who initially had BCA recurred with BCAC. Median overall survival was 18.1 years; 1-year, 3-year, and 5-year survival was 95.0%, 86.8%, and 84.2%, respectively. Long-term outcomes were associated with BCAC versus BCA, as well as the presence of spindle cell/ovarian stroma (both P < 0.05). CONCLUSIONS: Among patients undergoing surgery for BCT, associated malignancy was uncommon (10%) and no preoperative findings reliably predicted underlying BCAC. After excision of BCA, long-term outcomes were good; however, patients with BCAC had a worse long-term prognosis.

OBJECTIVE: To perform a matched comparison of surgical and postsurgical outcomes between our robotic and laparoscopic hepatic resection experience. BACKGROUND: The application of robotic technology and technique to liver surgery has grown. Robotic methods may have the potential to overcome certain laparoscopic disadvantages, but few studies have drawn a matched comparison of outcomes between robotic and laparoscopic liver resections. METHODS: Demographics, intraoperative variables, and postoperative outcomes among patients undergoing robotic (n = 57) and laparoscopic (n = 114) hepatic resections between November 2007 and December 2011 were reviewed. A 1:2 matched analysis was performed by individually matching patients in the robotic cohort to patients in the laparoscopic cohort based on demographics, comorbidities, performance status, and extent of liver resection. RESULTS: Matched patients undergoing robotic and laparoscopic liver resections displayed no significant differences in operative and postoperative outcomes as measured by blood loss, transfusion rate, R0 negative margin rate, postoperative peak bilirubin, postoperative intensive care unit admission rate, length of stay, and 90-day mortality. Patients undergoing robotic liver surgery had significantly longer operative times (median: 253 vs 199 minutes) and overall room times (median: 342 vs 262 minutes) compared with their laparoscopic counterparts. However, the robotic approach allowed for an increased percentage of major hepatectomies to be performed in a purely minimally invasive fashion (81% vs 7.1%, P < 0.05). CONCLUSIONS: This is the largest series comparing robotic to laparoscopic liver resections. Robotic and laparoscopic liver resection display similar safety and feasibility for hepatectomies. Although a greater proportion of robotic cases were completed in a totally minimally invasive manner, there were no significant benefits over laparoscopic techniques in operative outcomes.

OBJECTIVES: Before the advent of direct-acting antiviral therapy for hepatitis C virus, a large proportion of kidneys from donors with hepatitis C viremia were discarded. Hepatitis C virus is now amenable to effective treatment with excellent seronegativity rates. In this study, we review the outcomes of hepatitis C viremic kidneys transplanted into hepatitis C-naive recipients. MATERIALS AND METHODS: In this retrospective observational study, we examined 6 deceased donor kidneys with hepatitis C viremia that were transplanted into hepatitis C-naive recipients between March 2020 and April 2021 at a single center. Because of health insurance constraints, patients were treated for hepatitis C virus with glecaprevir/pibrentasvir for 8 weeks following seroconversion posttransplant. Primary outcome measured was viral seroconversion; secondary outcomes included graft function, posttransplant complications, and all-cause mortality. RESULTS: On average, patients seroconverted 6 days (range, 4-10 d) after transplant and began treatment 26 days (range, 15-37 d) after seroconversion. An 8-week course of antiviral treatment was successful in preventing acute hepatitis C virus infection in all patients. Posttransplant median creatinine was 1.96 mg/dL (range, 1-4.55 mg/dL), whereas median estimated glomerular filtration rate was 41.33 mL/min/1.73 m2 (range, 17-85 mL/min/1.73 m2). Patient survival rate was 66.7%, and death-censored graft survival rate was 100%. Two patients died from unrelated reasons: 1 from acute respiratory failure secondary to SARS-CoV-2 infection and 1 from posttransplant lymphoproliferative disorder. Two patients developed allograft rejection posttransplant (1 developed antibody mediated rejection, 1 developed borderline T-cell-mediated cellular rejection). Other major complications included neutropenia, fungal rash, SARS-CoV-2 infection, cytomegalovirus, BK virus, and Epstein-Barr virus reactivation. CONCLUSIONS: Use of hepatitis C-viremic donor kidneys for transplant is a safe option and has great potential to increase the kidney donor pool, as long as high index of suspicion is maintained for allograft rejection and opportunistic infections.

Statistically, the chance of having concurrent renal cell carcinoma (RCC), urothelial carcinoma of the bladder (UC), and a neuroendocrine tumor (NET) of the renal parenchyma is less than one in a trillion. Herein, we describe an unusual case of a 67-year-old female who presented with bilateral flank pain and severe gross hematuria. Cross-sectional imaging revealed two large heterogeneous, endophytic renal masses with a single enlarged paracaval lymph node. Diagnostic cystoscopy was performed for completion of gross hematuria evaluation and revealed a concurrent papillary bladder tumor. Percutaneous biopsies of bilateral renal masses revealed clear cell RCC involving the left kidney and well-differentiated NET involving the right kidney, and transurethral resection of the bladder tumor revealed high-grade nonmuscle invasive urothelial carcinoma. The patient elected to undergo bilateral nephroureterectomy, radical cystectomy, and retroperitoneal and pelvic lymphadenectomy. Final pathology confirmed the presence of three different malignancies: noninvasive high-grade papillary UC of the bladder (pTaN0), left renal clear cell RCC (pT2bN0), right renal well-differentiated NET, and a single paracaval lymph nodes positive for metastatic NET (pT2aN1).
RESUMEN
INTRODUCTION: Although gallbladder disease is more common in women, there is a trend toward more complicated cases in male patients. METHODS: All cholecystectomies captured by the National Surgical Quality Improvement Program database for the year 2016 were reviewed. This encompassed 38 736 records. Records were reviewed for age, sex, procedure performed, operative time, postoperative diagnosis, functional status, American Society of Anesthesiologists (ASA) class, preoperative lab values (total bilirubin, alkaline phosphatase, white blood cell count, and aspartate aminotransferase. Descriptive and inferential statistical analyses were conducted. RESULTS: Male patients are more likely to undergo cholecystectomy for a diagnosis of cholecystitis, gallstone pancreatitis, or cholangitis than women who are more likely to carry a diagnosis of biliary dyskinesia. The average operative time increases for both sexes as the patients become older. The average operative time is higher for men than women in all age groups and the variance becomes greater as the patients become older. Age, sex, postoperative diagnosis, ASA class, and functional status were all independently significant in predicting operative time. There was no difference in need for cholangiogram between the sexes. Female patients were more likely to have their cholecystectomy completed laparoscopically and they were more likely to have their surgery performed as an outpatient. CONCLUSION: These data show that women were more likely to present with uncomplicated gallbladder disease, while men were more likely to present with complicated gallbladder disease. This suggests that male patients present at a more advanced stage of disease.

PURPOSE: The aim of this study was to examine the link between psychological, behavioral, and social factors and survival in patients diagnosed with gastrointestinal cancer. METHODS: A cohort of gastrointestinal cancer patients were administered a battery of questionnaires that assessed trauma, depression, social support, sleep, diet, exercise, quality of life, tobacco and alcohol use, pain, and fatigue. Analyses included Pearson's correlations, analyses of variance, Kaplan Meier survival, and Cox regression analyses. RESULTS: Of the 568 patients, the majority were male (57.9%) and Caucasian (91.9%), with a mean age of 61 (S.D. = 10.7). The level of perceived social support was comparable to patients with other medical conditions. Sociodemographic predictors of social support included the number of years of education (r = 0.109, p = 0.05), marital status (F(6,387) = 5.465, p ≤ 0.001), and whether the patients' income met the family's basic needs (F(1,377) = 25.531, p < 0.001). Univariate analyses revealed that older age (p < 0.001), male gender (p = 0.007), being black (p = 0.005), diagnosis of hepatocellular carcinoma (p = 0.046), higher body mass index (p = 0.022), larger tumor size (p = 0.032), initial treatment including chemotherapy rather than surgery (p < 0.001), and lower level of perceived social support (p = 0.037) were associated with poorer survival. Using multivariate Cox regression and adjusting for all factors found to be significant in univariate survival analyses, older age (p = 0.024) and lower perceived social support (HR = 0.441, 95% CI = 0.233, 0.833; p = 0.012) were the factors that remained significantly associated with poorer survival. CONCLUSION: There are several biological and psychosocial factors that predict cancer mortality. Social support appears to be a robust factor affecting mortality in gastrointestinal cancer patients.

Background Hospital length of stay (LOS) remains an important, albeit nonspecific, metric in the analysis of surgical services. Modifiable factors to reduce LOS are few in number and the ability to practically take action is limited. Surgical scheduling of elective cases remains an important task in optimizing workflow and may impact the post-surgical LOS. Methods Retrospective data from a single tertiary care academic institution were analyzed from elective adult surgical cases performed from 2017 through 2019. Emergent or urgent add-on cases were excluded. Variables included primary procedure, age, diabetes status, American Society of Anesthesiologists (ASA) class, and surgical start time. Analysis of the median LOS following surgery was performed using Mann-Whitney tests and Cox hazards model. Matched-cohort analysis of mean total hospitalization costs was performed using the Student's t-test. Results 9,258 patients were analyzed across five surgical service lines, of which 777 patients had surgical start time after 3 PM. The median LOS for the after 3 PM group was 1 day longer than the before 3 PM start time cohort (3.0 vs 2.1, p < 0.001). Service line analysis revealed increased LOS for Orthopedics and Neurosurgery (3.0 vs 1.9, p < 0.001; 3.0 vs 2.0, p < 0.05). Multivariate analysis confirmed that start time before 3 PM predicted shorter LOS (HR = 1.214, 1.126-1.309; p < 0.001). Case-matched cost analysis for frequently performed orthopedic and neurosurgical cases with an after 3 PM start time failed to demonstrate a significant difference in total hospital charges. Conclusion Optimization of surgical services scheduling to increase the proportion of elective surgical cases started before 3 PM has the potential to decrease post-surgical LOS for adult patients undergoing Orthopedic or Neurosurgical procedures.
RESUMEN
BACKGROUND: Intraoperative radiation therapy (IORT) is an alternate accelerated form of radiation following breast-conserving surgery (BCS). Lack of data regarding long-term outcomes has limited adoption. We report our experience with IORT in patients undergoing BCS versus whole breast radiation therapy (WBRT). METHODS: Retrospective review of patients undergoing BCS with IORT versus WBRT (2012-2017). Inclusion: low grade, T1-2N0M0, estrogen receptor/progesterone receptor positive, and Her2-negative infiltrating ductal carcinomas. IORT was delivered as a single fraction of radiation (20 Gy) intraoperatively. Outcomes were compared using Fisher's test for discrete variables or Wilcoxon signed-rank test for continuous variables. Kaplan-Meier method was used to estimate disease-free survival (DFS). RESULTS: Fifty-one patients (44%) received IORT, and 66 (56%) received WBRT. There was no difference in age, tumor size, receptor status, or in-breast recurrence (1.9% vs 0%, all P > .05). Length of follow-up was longer in the WBRT group due to time to inception of IORT (mean ± SD: 44 ± 8.1 vs 73 ± 13 months, P < .001). There was no difference in DFS between the 2 groups (HR 2.5; P = .44). IORT patients experienced delay to BCS (mean ± SD: 38 ± 12.7 vs 27 ± 12.2 days, P < .001) likely due to coordination of care. Analysis demonstrated IORT patients would have traveled a mean distance of 20 miles to the closest WBRT center (range 1-70, miles) for a mean travel time of 31 minutes (range 4-90, minutes) per WBRT treatment. DISCUSSION: IORT produces noninferior oncologic outcomes and decreased skin toxicity compared with WBRT. It can be convenient for patients in rural regions with limited health care access.

Although gallbladder disease (GBD) is more common in females, we have noticed a trend toward more complicated cases in male patients. We reviewed all cholecystectomies performed at our institution over the last five years. After eliminating cases with confounding variables, we identified 1529 records. Charts were reviewed for age, gender, BMI, procedure performed, operative time, length of stay, and preoperative diagnosis. Descriptive and inferential statistical analyses were conducted along with linear regression. There were 1444 laparoscopic, 64 laparoscopic converted to open, and 21 primary open cases. Patients were 1008 (66%) females and 521 (34%) males. Average operative time was 89.8 minutes. Cholecystectomy averaged 17.7 minutes longer in males (P = 0.0046). Two per cent of female patients and 7.9 per cent male patient converted to open. Males were more likely to have complicated GBD, whereas women had uncomplicated disease. Average age was 51.9 years for males versus 42.7 years for females. Age, gender, BMI, length of stay, and preoperative diagnosis were all independently significant in predicting operative time. In our study, women presented with uncomplicated GBD, whereas men presented with complicated GBD. This suggests that male patients present at a later stage of disease.

Objectives: Research demonstrates a link between alcohol and tobacco use in the development of cancer, but limited research exists regarding substance use after a cancer diagnosis. In this study, we examine the rates of alcohol and tobacco use in advanced cancer patients, investigate the link between depression and tobacco and alcohol use pre- and post-diagnosis, and determine the relationship between illness perception and tobacco and alcohol use post-diagnosis.Methods: We performed a secondary data analysis on 2 prospective studies of patients with advanced gastrointestinal cancers. We administered a battery of questionnaires to assess substance use, depression, and illness perception. Results: Patients who reported tobacco use post-diagnosis had higher levels of depressive symptoms when compared to patients with a history of tobacco use or no alcohol or tobacco use (Kruskal-Wallis = 25.77, p < .0125). Patients who reported being more emotionally affected by their illness reported greater tobacco use (Mann-Whitney U = 17, 284.5, p < .003). Conclusions: Tobacco use post-diagnosis was associated with higher levels of depression.

We have proposed that the mechanisms of alloengraftment and variable acquired tolerance can be facilitated by minimum posttransplant immunosuppression. It was further suggested that the efficacy of minimalistic treatment could be enhanced by preoperative recipient conditioning with an antilymphoid antibody preparation. A total of 76 adults (38 hepatitis C virus [HCV], 38 HCV) were infused with 30 mg alemtuzumab before primary cadaveric liver transplantation and maintained afterward on daily monotherapy unless breakthrough rejection mandated additional agents. In stable patients, the intervals between tacrolimus doses were lengthened ("spaced weaning") after approximately 4 months. Eighty-four contemporaneous nonlymphoid-depleted liver recipients (58 HCV, 26 HCV) were treated with conventional postoperative immunosuppression. The overall incidence of rejection was similar with the two strategies of immunosuppression. With follow-ups of 14 to 22 months, patient and primary graft survival in HCV cases are 97% and 90%, respectively, with alemtuzumab depletion plus minimal immunosuppression versus 71% and 70%, respectively, under conventional immunosuppression. In HCV recipients, current patient and graft survival in the alemtuzumab-pretreated group are 71% and 70% versus 65% and 54%, respectively, under conventional treatment. With both strategies of immunosuppression, the adverse effect of preexisting HCV on survival parameters and graft function already was significant at the 1-year milestone, but its extent was not evident until the second year. With or without HCV, 62% of the 64 surviving lymphoid-depleted patients are on spaced immunosuppression, and four patients receive no immunosuppression. Lymphoid depletion with alemtuzumab and minimalistic maintenance immunosuppression is a practical strategy of liver transplantation in HCV recipients but not HCV recipients.
