Cancer incidence, type, and survival after bariatric surgery.

BACKGROUND: Many types of cancer have been found to be associated with being overweight or obese. Literature has demonstrated a reduction in cancer risk in patients who have undergone bariatric surgery. OBJECTIVES: To compare the incidence and types of new cancer diagnoses, cumulative cancer incidence, cancer risk, and overall survival in patients with obesity who underwent bariatric surgery with that of those who did not. SETTING: Community-based academic medical center. METHODS: We retrospectively compared the rates and types of new incident cancers in a bariatric surgery cohort (Bariatric group) with those of a non-surgical cohort (Comparison group). The Comparison group was chosen from patients who had a clinic visit in our health system within 30 days of each bariatric surgical operation and matched on age, sex, and body mass index. Patients who had a cancer diagnosis prior to having bariatric surgery were excluded from the Bariatric group and patients who had a cancer diagnosis prior to the clinic visit on which they were matched were excluded from the Comparison group. Relative risk of cancer by type was calculated. Chi-square and Fisher exact tests were used for categorical data analysis, and Wilcoxon rank-sum for continuous data. The Kaplan Meier estimator with the log-rank test was used to compare overall survival between groups, while competing risks survival analysis with the Gray test for equality was used to compare cancer incidence in the Surgery group with that in the Comparison group. RESULTS: After matching, the Bariatric group had 1593 patients and the Comparison group had 2156. The Bariatric and Comparison groups had 82 and 222 new incident cancer cases, respectively (P < .001). The 10-year incidence of any new cancer in the Bariatric group was 6.5%, compared with an incidence of 12.1% in the Comparison group (P < .001). Relative risk of cancer in the Bariatric group was lower than that of the Comparison group, with the greatest differences in endometrial (88.8%), kidney (77.4%), thyroid (72.9%), and ductal carcinoma in situ (71.2%) cancers. The 10-year overall survival rate was higher in the Bariatric group than in the Comparison group, 93.3% versus 80.6%, respectively (P < .001). CONCLUSIONS: Bariatric surgery reduces the risk for developing cancer and offers survival advantage when compared with similar patients who do not undergo bariatric surgery.

Nonoperative Treatment of Diverticulitis and Appendicitis: Which Antibiotic Regimen Fails?

INTRODUCTION: Diverticulitis and appendicitis are common emergency general surgical conditions. Both can be treated with antibiotics alone; however, no antibiotic regimen has been identified as superior to others. In this study, we review different antibiotic regimens and their rates of failure. METHODS: Retrospective cohort study of patients treated empirically with antibiotics for diverticulitis or appendicitis from January 1, 2018, to December 31, 2020, at an independent academic hospital in the Midwest. RESULTS: A total of 587 (appendicitis, n = 43; diverticulitis, n = 544) patients were included in the cohort. They were equally male (49%) and female (51%) with a median age of 59 y. Three major antibiotic classes were compared: cephalosporin + metronidazole (C + M), penicillins, and quinolone + metronidazole. Appendicitis patients were more likely to receive C + M for empiric treatment (73%, P < 0.001), while diverticulitis patients were more likely to receive quinolone + metronidazole (45%, P < 0.001). Patients empirically treated with antibiotics for appendicitis were more likely than those treated for diverticulitis to require additional antibiotics or procedure within 90 d (33% versus 13%, respectively; P = 0.005). Empiric treatment with C + M for diverticulitis was more likely to be associated with the need for additional antibiotics or procedures within 90 d than treatment with other regimens (P = 0.003). Choice of antibiotic for empiric treatment did not correlate with death at 90 d for appendicitis or diverticulitis. Diverticulitis patients who were initially treated as inpatients and were prescribed C + M at hospital discharge had a higher rate of death than those who were prescribed the other antibiotics (P = 0.04). CONCLUSIONS: Empiric antibiotic treatment of appendicitis is more likely to be associated with additional antibiotics or procedure when compared with diverticulitis; however, antibiotic choice did not correlate with any of the other outcomes. Empiric treatment with a C + M for diverticulitis was more likely to be correlated with the need for additional antibiotics or procedure within 90 d.

Food cravings after bariatric surgery: comparing laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass.

BACKGROUND: Research suggests that food choices, preferences, and tastes change after bariatric surgery, but evidence regarding changes in food cravings is mixed. OBJECTIVES: The primary aim of this cohort study was to compare food cravings during the first year following bariatric surgery in patients who had undergone sleeve gastrectomy (SG) versus Roux-en-Y gastric bypass (RYGB). SETTING: Integrated multispecialty health system, United States. METHODS: Patients aged ≥ 18 years seen between May 2017 and July 2019, provided informed consent, completed the Food Craving Inventory (FCI), and had ≥ 1 year of follow-up after undergoing primary SG or RYGB were included in the study. Secondary data captured included psychological and behavioral measures. Preoperative and postoperative (3, 6, 9, and 12 months) FCI scores of patients who underwent SG and RYGB were compared. RESULTS: Some attrition occurred postoperatively (N = 187 at baseline, 141 at 3 months, 108 at 6 months, 89 at 9 months, and 84 at 12 months). No significant relationship between pre- or postoperative food cravings and surgery type was found except on the carbohydrate subscale. Patients with higher preoperative food addiction symptoms were not more likely to experience an earlier reoccurrence of food cravings during the first 12 months after surgery. Likewise, patients with higher levels of preoperative depression and anxiety were not more likely to have early reoccurrence of food cravings during the first 12 months after surgery; however, those with higher PHQ9 scores at baseline had uniformly higher food craving scores at all timepoints (pre-surgery, 3 m, 6 m, 9 m, and 12 m). CONCLUSIONS: Results suggest that food cravings in the year after bariatric surgery are equivalent by surgery type and do not appear to be related to preoperative psychological factors or eating behaviors. LEVEL OF EVIDENCE: Level III: Evidence obtained from well-designed cohort.

Understanding clinical implementation coordinators' experiences in deploying evidence-based interventions.

PURPOSE: The fluoroquinolone restriction for the prevention of Clostridioides difficile infection (FIRST) trial is a multisite clinical study in which sites carry out a preauthorization process via electronic health record-based best-practice alert (BPA) to optimize the use of fluoroquinolone antibiotics in acute care settings. Our research team worked closely with clinical implementation coordinators to facilitate the dissemination and implementation of this evidence-based intervention. Clinical implementation coordinators within the antibiotic stewardship team (AST) played a pivotal role in the implementation process; however, considerable research is needed to further understand their role. In this study, we aimed to (1) describe the roles and responsibilities of clinical implementation coordinators within ASTs and (2) identify facilitators and barriers coordinators experienced within the implementation process. METHODS: We conducted a directed content analysis of semistructured interviews, implementation diaries, and check-in meetings utilizing the conceptual framework of middle managers' roles in innovation implementation in healthcare from Urquhart et al. RESULTS: Clinical implementation coordinators performed a variety of roles vital to the implementation's success, including gathering and compiling information for BPA design, preparing staff, organizing meetings, connecting relevant stakeholders, evaluating clinical efficacy, and participating in the innovation as clinicians. Coordinators identified organizational staffing models and COVID-19 interruptions as the main barriers. Facilitators included AST empowerment, positive relationships with staff and oversight/governance committees, and using diverse implementation strategies. CONCLUSION: When implementing healthcare innovations, clinical implementation coordinators facilitated the implementation process through their roles and responsibilities and acted as strategic partners in improving the adoption and sustainability of a fluoroquinolone preauthorization protocol.

Temporal Artery Biopsy: When Is It Worth the Headache?

BACKGROUND: Temporal artery biopsy is ordered when clinical symptoms and an elevated C-reactive protein values and/or erythrocyte sedimentation rates suggest giant cell arteritis. The percentage of temporal artery biopsies positive for giant cell arteritis is low. The objectives of our study were to analyze the diagnostic yield of temporal artery biopsies at an independent academic medical center and to develop a risk stratification model for triaging patients for possible temporal artery biopsy. METHODS: We retrospectively reviewed the electronic health records of all patients who underwent temporal artery biopsy in our institution from January 2010 through February 2020. We compared clinical symptoms and inflammatory marker (C-reactive protein and erythrocyte sedimentation rate) values of patients whose specimens were positive for giant cell arteritis with those of patients with negative specimens. Statistical analysis included descriptive statistics, chi-square test, and multivariable logistic regression. A risk stratification tool, which included point assignments and measures of performance, was developed. RESULTS: Of 497 temporal artery biopsies for giant cell arteritis performed, 66 were positive and 431 were negative. Jaw/tongue claudication, elevated inflammatory marker values, and age were associated with a positive result. Using our risk stratification tool, 3.4% of low-risk patients, 14.5% of medium-risk patients, and 43.9% of high-risk patients were positive for giant cell arteritis. CONCLUSIONS: Jaw/tongue claudication, age, and elevated inflammatory markers were associated with positive biopsy results. Our diagnostic yield was much lower when compared with a benchmark yield determined in a published systematic review. A risk stratification tool was developed based on age and the presence of independent risk factors.

Trauma and Death in the Emergency Department: A Time to PAUSE (Promoting Acknowledgment, Unity, and Sympathy at the End of Life).

BACKGROUND: Witnessing death can be difficult and emotionally draining for health care workers and presents a risk factor for burnout. The practice of a ritual pause at patient death to recognize the patient as a person, reflect, and acknowledge the health care team is an emerging intervention that has not been well studied in trauma. OBJECTIVE: This study aims to explore the effect of a team pause on trauma team member attitudes after emergency department patient death. METHODS: This is a pre- and postintervention study of the implementation of a Trauma PAUSE (Promoting Acknowledgment, Unity, and Sympathy at the End of Life) conducted from March 2018 to June 2020. RESULTS: A total of 466 participated in this study. Emergency department employee responses to the pre- (296 of 745 employees contacted responded) and postimplementation surveys (170 of 732 employees contacted responded) were compared. Although not statistically significant, responses to the postsurvey suggested an increased connection to patients and belief in the need for a moment of silence following a death. Employees who had participated in a PAUSE (57/170) reported improvements in internal conflict, feeling of emptiness, resilience, and ability to move on to the next task. Overall, 84.2% (48/57) of Trauma PAUSE participants were satisfied with the Trauma PAUSE. CONCLUSION: The Trauma PAUSE is a meaningful way to help trauma staff members find peace, maintain resiliency, and readily shift their focus to providing care to other patients.

Patient characteristics and diagnostic tests associated with syncopal falls: A Southwestern surgical congress multicenter study.

BACKGROUND: Patients suspected of syncope frequently undergo laboratory and imaging studies to determine the etiology of the syncope. Variability exists in these workups across institutions. The purpose of this study was to evaluate the utilization and diagnostic yield of these workups and the patient characteristics associated with syncopal falls. METHODS: A multi-institutional retrospective review was performed on adult patients admitted after a fall between 1/2017-12/2018. Syncopal falls were compared to non-syncopal falls. RESULTS: 4478 patients were included. There were 795 (18%) patients with a syncopal fall. Electrocardiogram, troponin, echocardiogram, CT angiography (CTA), and carotid ultrasound were more frequently tested in syncope patients compared to non-syncope patients. Syncope patients had higher rates of positive telemetry/Holter monitoring, CTAs, and electroencephalograms. CONCLUSION: Patients who sustain syncopal falls frequently undergo diagnostic testing without a higher yield to determine the etiology of syncope.

Health care costs for adolescents and young adults with cancer: a Wisconsin community-based hospital study between 2005 and 2020.

INTRODUCTION: Adolescents and young adults (AYA) with cancer are at risk of high cumulative healthcare system costs potentially associated with poor health and financial outcomes. Although this has been studied at academic centers, little data on AYA costs at community-based practices exist. The goals of this study were to understand direct health care costs for AYA patients, identify factors for high costs, and assess how total health care costs may relate to survival. METHODS: AYA patients (15-39 years) treated at a community hospital in Wisconsin (USA) between 2005 and 2020 were identified. Patient demographics, cancer characteristics, therapies, support services, and all direct health care charges (including up to 1 year prior to diagnosis to capture any diagnostic workup) were collected. Logistic and Cox proportional hazard regression models identified factors associated with high costs and survival, respectively. RESULTS: The 388 AYA patients had a median follow-up of 9 years (97% survival). Most were 30-39 years (62%), female (61%), white (95%), diagnosed early-stage (85%), and underwent surgery (83%). Complete health care costs were available for 233 patients (60%). Median total costs per patient were $123 K (range, $73-$215 K). On adjusted analysis, higher direct health care costs (> $125 K) were associated with greater odds of hospital admissions (odds ratio [OR] = 1.7, 95% CI = 1.35-2.27), chemotherapy (OR = 4.1, 95% CI = 1.44-12.70), and breast cancer diagnosis (OR = 3.8, 95% CI = 1.07-14.70). Living farther from the hospital (OR = 0.1, 95% CI = 0.02-0.50), later year of diagnosis (OR = 0.7, 95% CI = 0.55-0.77), and uninsured/unknown insurance status (OR = 0.1, 95% CI = 0.01-0.57) were associated with decreased odds of having higher health care costs. On adjusted analysis, death was associated with greater odds of higher direct health care costs per $125 K (hazards ratio [HR] = 7.9, 95% CI = 2.22-27.80) and radiation (HR = 31.8, 95% CI = 3.15-321) but lower odds of hormone therapy (HR = 0.1, 95% CI = 0.01-0.72) and later year of diagnosis (HR = 0.3, 95% CI = 0.12-0.60). CONCLUSION: High direct health care costs among AYA patients are associated with hospital admissions, chemotherapy, breast cancer diagnosis, hospital proximity, and earlier year of diagnosis. Death was associated with high direct health care costs, earlier years of diagnosis, and radiation therapy. Total health care costs in community-based hospitals should be considered in the context of AYA patients with cancer.

External Validation of AJCC Eighth Edition of Non-small-cell Lung Cancer Staging Among African Americans.

INTRODUCTION: The American Joint Committee on Cancer (AJCC) eighth staging classification system for non-small-cell lung cancer was based on data from a multinational study consisting of 94,708 patients. African Americans were not included in this large database. MATERIALS AND METHODS: The authors aimed to compare the performance of the AJCC eighth staging system with that of the seventh in predicting overall survival among African Americans utilizing the National Cancer Database. Cases with T- and M- categories were classified into 2 groups based on the AJCC seventh and eighth edition staging systems. Kaplan-Meier curves for overall survival were then constructed for each subgroup. Concordance index was computed using Uno's methodology to assess the overall performance between the 2 staging systems in predicting the mortality. Time-dependent area under the curve was calculated at each follow-up event for the seventh and eighth edition clinical and pathologic staging using an inverse probability of censoring weighted methodology. A 2-sided P-value < .05 was considered to show statistical significance. RESULTS: The database identified a total of 70,606 African American patients in the study period of 2004 through 2014. Area under the curve values were consistently higher for the eighth edition scheme compared with the seventh edition (concordance 0.630 vs. 0.624, respectively; P < .0001 for clinical staging scheme and 0.596 vs. 0.591, respectively; P = .01 for pathologic staging scheme). CONCLUSION: The AJCC eighth edition staging system showed better prognostic value in predicting overall survival when compared with the AJCC seventh edition staging scheme among African American patients with non-small-cell lung cancer.

Utilization of Surgery and Its Impact on Survival in Patients With Early Stage Small-cell Lung Cancer in the United States.

INTRODUCTION: For patients with T1 or T2 N0 M0 small-cell lung cancer (SCLC), lobectomy followed by chemotherapy is the standard of care. However, because of its tendency for early dissemination, patients are often treated with concurrent chemo-radiation without surgery. This study was conducted to evaluate the utilization of surgery and its impact on survival in patients with early stage SCLC. MATERIALS AND METHODS: The National Cancer Database was queried to identify patients with T1 or T2 N0 M0 SCLC diagnosed from 2004 to 2013. Multivariate logistic regression modeling was utilized to identify factors associated with receipt of surgery. Patients were stratified into 3 groups: chemo-radiation, surgery followed by chemotherapy, and surgery followed by chemotherapy and prophylactic cranial irradiation (PCI). Kaplan-Meier estimators and Cox proportional-hazards regression were used to compare overall survival. Patients were matched on the propensity score. RESULTS: A total of 3879 SCLC cases were identified. Of those cases, 80.7% received chemo-radiation. Surgery followed by chemotherapy with or without PCI was associated with better median overall survival (93.0 months [lower 95% confidence interval (CI), 72.5] and 61.7 months [95% CI, 51.8-76.5], respectively) compared with chemo-radiation (31.2 months [95% CI, 26.3-37.0]). PCI offered survival benefit in addition to surgery and chemotherapy (hazard ratio, 0.75). CONCLUSIONS: Our study showed a significant survival benefit with surgery (lobectomy or more), adjuvant chemotherapy, and PCI in patients with T1-T2 N0 M0 SCLC.
