Safety and Efficacy of Inpatient Infliximab Rescue Therapy for Acute Crohn's Disease Flares.

PURPOSE: Describe the safety, complications, and need for urgent surgery in patients requiring inpatient rescue infliximab for acute Crohn's disease (CD) flare. BACKGROUND: Infliximab is increasingly used for patients hospitalized with acute severe ulcerative colitis as rescue therapy; however, optimal management for patients hospitalized for CD flares remains unclear. METHODS: A single-institution retrospective study of patients aged 18+ admitted from 2008 to 2020 with acute Crohn's flare requiring induction of rescue infliximab therapy. Outcomes included postoperative and medication-related complications and need for urgent surgery. RESULTS: 52 patients were included in analysis; 8% required surgery on index admission, and 19% required surgery within 90 days of infliximab. Postoperative complications included 1 anastomotic leak, 3 superficial wound infections, 3 prolonged ileus, and 1 urinary infection. There were no adverse reactions to infliximab infusion, and medical complication rates were low. Patients with penetrating disease were more likely to undergo surgery within 90 days of infliximab (43% vs 8%; P = .01). Mean LOS was longer for patients undergoing surgery within 90 days of therapy compared to those who did not (13.4 vs 8.3 days, P = .04). CONCLUSION: Inpatient rescue infliximab is safe for treating acute Crohn's disease flare in addition to standard steroid therapy. The majority of patients hospitalized with Crohn's flare requiring rescue infliximab avoided surgery with low postoperative and medication-related complications. More research is needed to clarify the optimal rescue infliximab therapy dosage.

Mental health disorders as a risk factor in young patients with rectal prolapse.

BACKGROUND: Rectal prolapse (RP) typically presents in the elderly, though it can present in younger patients lacking traditional risk factors. The current study compares medical and mental health history, presentation, and outcomes for young and older patients with RP. METHODS: This is a single-center retrospective review of patients who underwent abdominal repair of RP between 2005 and 2019. Individuals were dichotomized into two groups based on age greater or less than 40 years. RESULTS: Of 156 patients, 25 were < 40. Younger patients had higher rates of diagnosed mental health disorders (80% vs 41%, p < 0.001), more likely to take SSRIs (p = .02), SNRIs (p = .021), anxiolytics (p = 0.033), and antipsychotics (p < 0.001). Younger patients had lower preoperative incontinence but higher constipation. Both groups had low rates of recurrence (9.1% vs 11.6%, p = 0.73). CONCLUSIONS: Young patients with RP present with higher concomitant mental health diagnoses and represent unique risk factors characterized by chronic straining compared to pelvic floor laxity.

United States-Based Colorectal Cancer Surgical Trials Lack Representation and Adequate Reporting of Racially and Ethnically Diverse Participants: Systematic Review and Regression Analysis.

BACKGROUND: Despite the established National Institute of Health Revitalization Act, which aims to include ethnic and racial minority representation in surgical trials, racial and ethnic enrollment disparities persist. OBJECTIVE: To assess the proportion of patients from minority races and ethnicities that are included in colorectal cancer surgical trials and reporting characteristics. DATA SOURCES: Search was performed using MEDLINE (Ovid), Embase, Web of Science, and Cochrane Central. STUDY SELECTION: Inclusion criteria included 1) trials performed in the United States between January 1, 2000, and May 30, 2022; 2) patients with colorectal cancer diagnosis; and 3) surgical intervention, technique, or postoperative outcome. Trials evaluating chemotherapy, radiotherapy, or other nonsurgical interventions were excluded. INTERVENTIONS: Pooled proportion and regression analysis was performed to identify the proportion of patients by race and ethnicity included in surgical trials and the association of year of publication and funding source. MAIN OUTCOME MEASURES: Proportion of trials reporting race and ethnicity and proportion of participants by race and ethnicity included in surgical trials. RESULTS: We screened 10,673 unique publications, of which 80 were examined in full text. Fifteen studies met our inclusion criteria. Ten (66.7%) trials did not report race, 3 reported races as a proportion of White participants only, and 3 reported 3 or more races. There was no description of ethnicity in 11 (73.3%) trials, with 2 describing "non-Caucasian" as ethnicity and 2 describing only Hispanic ethnicity. Pooled proportion of White participants was 81.3%, of Black participants was 6.2%, of Asian participants was 3.6%, and of Hispanic participants was 3.5%. LIMITATIONS: A small number of studies was identified that reported racial or ethnic characteristics of their participants. CONCLUSIONS: Both race and ethnicity are severely underreported in colorectal cancer surgical trials. To improve outcomes and ensure the inclusion of vulnerable populations in innovative technologies and novel treatments, reporting must be closely monitored.

Early C-reactive protein after colorectal surgery is not predictive of anastomotic leak: a retrospective cohort study.

PURPOSE: Prior studies suggest postoperative C-reactive protein (CRP) trends are sensitive for predicting anastomotic leak (AL) after elective colorectal surgery. However, in the setting of enhanced recovery pathways, multi-day CRP trends may not be feasible. This study aimed to assess the realistic and clinical utility of CRP in prediction of AL. METHODS: A retrospective review of patients who underwent elective colectomy or proctectomy from January 2019 to October 2020 at a single institution was performed. Comorbidities, operative characteristics, and perioperative outcomes were recorded. CRP was checked routinely on POD1 and on a clinical basis subsequently. The association between 10-point change in CRP-POD1 and AL was evaluated using multivariable logistic regression. The relationships between CRP-POD3, CRP-POD1, and AL were assessed using exploratory analyses. RESULTS: Among 332 patients, 23 (6.9%) developed AL, of which 9 cases (39%) were diagnosed upon readmission. AL was not associated with mortality. Median length of stay was 3 days (IQR 2-5). Median days to AL diagnosis was 7 (IQR 4-15). Adjusting for diverting stoma, steroid use, diagnosis, and open surgery, each 10-point increase in CRP was associated with increased odds of AL (OR 1.12, 95% CI 1.03-1.21, p=0.008). CRP-POD1 had poor discriminant utility for detecting AL (AUC 0.62, 95% CI = 0.494-0.746; p=0.061). CONCLUSION: CRP on POD1 is not a reliable method to predict a leak, and trending CRP may not be practical with decreasing lengths of stay in colorectal surgery.

Impact of National Accreditation Program for Rectal Cancer guidelines on surgical margin status.

BACKGROUND: The American College of Surgeons established the National Accreditation Program for Rectal Cancer (NAPRC) to standardize rectal cancer care. We sought to assess the impact of NAPRC guidelines at a tertiary care center on surgical margin status. MATERIALS AND METHODS: The Institutional NSQIP database was queried for patients with rectal adenocarcinoma undergoing surgery for curative intent two years prior to and following implementation of NAPRC guidelines. Primary outcome was surgical margin status before (pre-NAPRC) versus after (post-NAPRC) implementation of NAPRC guidelines. RESULTS: Surgical pathology in five (5%) pre-NAPRC and seven (8%) post-NAPRC patients had positive radial margins (p = 0.59); distal margins were positive in three (3%) post-NAPRC and six (7%) post-NAPRC patients (p = 0.37). Local recurrence was observed in seven (6%) pre-NAPRC patients, there were no recurrences to date in post-NAPRC patients (p = 0.15). Metastasis was observed in 18 (17%) pre-NAPRC patients and four (4%) post-NAPRC patients (p = 0.55). CONCLUSION: NAPRC implementation was not associated with a change in surgical margin status for rectal cancer at our institution. However, the NAPRC guidelines formalize evidence-based rectal cancer care and we anticipate that improvements will be greatest in low-volume hospitals which may not utilize multidisciplinary collaboration.

Retention of Knowledge After Opioid Education in Surgical Interns.

BACKGROUND: In many academic centers, opioid prescribing is managed primarily by residents with little or no formal opioid education. The present study evaluates intern knowledge and comfort with appropriate opioid prescribing 7 months after an organized opioid education effort. MATERIALS AND METHODS: A repeat knowledge and attitude survey was sent to surgical interns who had completed an initial opioid education training session 7 months before the study. Results were compared to post-education assessment results in the same cohort. SETTING: 16 general surgery and podiatric surgery interns at a single academic medical center. RESULTS: The mean percentage of correct answers on follow-up was 67.6% identical to the average post-session score of 67.6%. Interns reported comfort with opioid prescribing increased to a mean score of 5.9 (out of 10) on follow-up compared to post-session score of 5.19. CONCLUSIONS: Surgical interns have significant gaps in knowledge for optimal prescribing and management of opioid prescriptions. Targeted education demonstrates significant and lasting improvement in opioid assessment scores, but there remains room for improvement.

Gastrointestinal Malignancies and the COVID-19 Pandemic: Evidence-Based Triage to Surgery.

BACKGROUND: The COVID-19 pandemic has led to widespread cancelation of electively scheduled surgeries, including for colorectal, pancreatic, and gastric cancer. The American College of Surgeons and the Society of Surgical Oncology have released guidelines for triage of these procedures. We seek to synthesize available evidence on delayed resection and oncologic outcomes, while also providing a critical assessment of the released guidelines. METHODS: A systematic review was conducted to identify literature between 2005 and 2020 investigating the impact of time to surgery on oncologic outcomes in colorectal, pancreatic, and gastric cancer. RESULTS: For colorectal cancer, 1066 abstracts were screened and 43 papers were included. In primarily resected colon cancer, delay over 30 to 40 days is associated with lower survival. In rectal cancer, time to surgery over 7 to 8 weeks following neoadjuvant therapy is associated with decreased survival. Three hundred ninety-four abstracts were screened for pancreatic cancer and nine studies were included. Two studies demonstrate increased unexpected progression with delayed surgery over 30 days. Out of 633 abstracts screened for gastric cancer, six studies were included. No identified study demonstrated worse survival with increased time to surgery. CONCLUSION: Moderate evidence suggests that delayed resection of colorectal cancer worsens survival; the impact of time to surgery on gastric and pancreatic cancer outcomes is uncertain. Early resection of gastrointestinal malignancies provides the best chance for curative therapy. During the COVID-19 pandemic, prioritization of procedures should account for available evidence on time to surgery and oncologic outcomes.

Cell based therapy enhances activation of ventral premotor cortex to improve recovery following primary motor cortex injury.

Stroke results in enduring damage to the brain which is accompanied by innate neurorestorative processes, such as reorganization of surviving circuits. Nevertheless, patients are often left with permanent residual impairments. Cell based therapy is an emerging therapeutic that may function to enhance the innate neurorestorative capacity of the brain. We previously evaluated human umbilical tissue-derived cells (hUTC) in our non-human primate model of cortical injury limited to the hand area of primary motor cortex. Injection of hUTC 24 h after injury resulted in significantly enhanced recovery of fine motor function compared to vehicle treated controls (Moore et al., 2013). These monkeys also received an injection of Bromodeoxyuridine (BrdU) 8 days after cortical injury to label cells undergoing replication. This was followed by 12 weeks of behavioral testing, which culminated 3 h prior to perfusion in a final behavioral testing session using only the impaired hand. In this session, the neuronal activity initiating hand movements leads to the upregulation of the immediate early gene c-Fos in activated cells. Following perfusion-fixation of the brain, sections were processed using immunohistochemistry to label c-Fos activated cells, pre-synaptic vesicle protein synaptophysin, and BrdU labeled neuroprogenitor cells to investigate the hypothesis that hUTC treatment enhanced behavioral recovery by facilitating reorganization of surviving cortical tissues. Quantitative analysis revealed that c-Fos activated cells were significantly increased in the ipsi- and contra-lesional ventral premotor but not the dorsal premotor cortices in the hUTC treated monkeys compared to placebo controls. Furthermore, the increase in c-Fos activated cells in the ipsi- and contra-lesional ventral premotor cortex correlated with a decrease in recovery time and improved grasp topography. Interestingly, there was no difference between treatment groups in the number of synaptophysin positive puncta in either ipsi- or contra-lesional ventral or dorsal premotor cortices. Nor was there a significant difference in the density of BrdU labeled cells in the subgranular zone of the hippocampus or the subventricular zone of the lateral ventricle. These findings support the hypothesis that hUTC treatment enhances the capacity of the brain to reorganize after cortical injury and that bilateral plasticity in ventral premotor cortex is a critical locus for this recovery of function. This reorganization may be accomplished through enhanced activation of pre-existing circuits within ventral premotor, but it could also reflect ventral premotor projections to the brainstem or spinal cord.
