Time Is Survival: Continuing Education on Sepsis for Neurosurgical Critical Care Nurses.

BACKGROUND: Early identification of sepsis among neurosurgical critical care patients is a significant challenge because of the many possible confounding variables that lead to altered mental status in this specific patient population. Nurses' knowledge, attitudes, confidence, and practices related to the early identification and management of sepsis are crucial to patients' survival. METHOD: This evidence-based intervention project implemented continuing education for neurosurgical critical care nurses on the early signs and symptoms of sepsis and the management of sepsis according to the Surviving Sepsis Campaign (SSC) Guidelines. RESULTS: Continuing education on sepsis increased neurosurgical critical care nurses' knowledge of the SSC 1-hour sepsis bundle, reported confidence in the management of sepsis, and likelihood of assessing for sepsis. CONCLUSION: Continuing education for neurosurgical critical care nurses on the signs and symptoms of sepsis and the SSC Guidelines is necessary and may improve patient outcomes.

A Randomized Feasibility Trial Comparing Surveillance Regimens for Patients with Low and Low-Intermediate Risk Non-Muscle Invasive Bladder Cancer.

BACKGROUND: Surveillance regimens for non-muscle invasive bladder cancer (NMIBC) are disparate and controlled trials could inform guidelines. The feasibility of randomizing patients to variable frequency surveillance is unknown. OBJECTIVES: To determine patient willingness to randomization to high frequency (HF) versus low frequency (LF) surveillance regimen for NMIBC and compare patient comfort and healthcare costs across regimens. METHODS: A non-blinded, two-arm, randomized-controlled study of patients with low or low-intermediate risk NMIBC was conducted at two institutions where patients were offered randomization to HF vs. LF surveillance following initial tumor resection. The HF group underwent cystoscopy every three months for 2 years, then every 6 months for 2 years, then annually. The LF group underwent cystoscopy at 9 months following the 3-month cystoscopy, then annually. Assuming 75% of patients approached would agree to enrollment, a sample size of n = 35 patients per arm provided a one-sided 95% exact Clopper-Pearson confidence lower-limit of 60%. RESULTS: Of 70 patients approached, 45 (64.3%) agreed to participate and 25 (35.7%) declined enrollment due to preference for HF. Twelve biopsies were performed, including 4 (19%) of 21 patients in the HF group and 8 (33.3%) of 24 patients in the LF group. Disease recurrence (low grade Ta) was observed in 3 (14.3%) and 5 (20.8%) patients in the HF and LF groups, respectively. No patients experienced high grade recurrence or progression. Both groups had similar patient-reported procedure-related discomfort and quality of life measures over time. Patient out-of-pocket cost and healthcare systems costs were $383.80 more per patient annually in the HF group. CONCLUSIONS: Randomization to variable frequency surveillance is challenging as over a third of patients declined participation. However, these data provide important preliminary insights into the potential effects of surveillance frequency on oncologic and economic outcomes in patients with low and low-intermediate risk bladder cancer.

Bladder tumor ILC1s undergo Th17-like differentiation in human bladder cancer.

PURPOSE: Human innate lymphoid cells (hILCs) are lineage-negative immune cells that do not express rearranged adaptive antigen receptors. Natural killer (NK) cells are hILCs that contribute to cancer defense. The role of non-NK hILCs in cancer is unclear. Our study aimed to characterize non-NK hILCs in bladder cancer. EXPERIMENTAL DESIGN: Mass cytometry was used to characterize intratumoral non-NK hILCs based on 35 parameters, including receptors, cytokines, and transcription factors from 21 muscle-invasive bladder tumors. Model-based clustering was performed on t-distributed stochastic neighbor embedding (t-SNE) coordinates of hILCs, and the association of hILCs with tumor stage was analyzed. RESULTS: Most frequent among intratumoral non-NK hILCs were hILC1s, which were increased in higher compared with lower stage tumors. Intratumoral hILC1s were marked by Th17-like phenotype with high RORγt, IL-17, and IL-22 compared to Th1 differentiation markers, including Tbet, perforin, and IFN-γ. Compared with intratumoral hILC2s and hILC3s, hILC1s also had lower expression of activation markers (NKp30, NKp46, and CD69) and increased expression of exhaustion molecules (PD-1 and Tim3). Unsupervised clustering identified nine clusters of bladder hILCs, which were not defined by the primary hILC subtypes 1-3. hILC1s featured in all the nine clusters indicating that intratumoral hILC1s displayed the highest phenotypic heterogeneity among all hILCs. CONCLUSIONS: hILC1s are increased in higher stage tumors among patients with muscle-invasive bladder cancer. These intratumoral hILC1s exhibit an exhausted phenotype and Th17-like differentiation, identifying them as potential targets for immunotherapy.

Urinary Diversion Disparity Following Radical Cystectomy for Bladder Cancer in the Hispanic Population.

OBJECTIVE: To determine if disparities in quality of surgical care exist between Hispanics and non-Hispanics undergoing radical cystectomy for bladder cancer. MATERIALS AND METHODS: An observational cohort study was conducted retrospectively on patients who underwent radical cystectomy for urothelial carcinoma of the bladder at our institution between January 2005 and July 2018. Data was collected on demographic, clinical, and pathological characteristics of patients, including self-reported ethnicity. Univariable and multivariable logistic or linear regression analyses were used to evaluate the association of ethnicity with receipt of neoadjuvant chemotherapy, utilization of laparoscopic surgery, number of lymph nodes removed, and continent urinary diversion. RESULTS: We identified 507 patients in our database out of which, 136 (27%) were Hispanic and 371 (73%) were non-Hispanic. Compared to non-Hispanics, Hispanics had a higher body mass index (26.9 kg/m2 vs 28.2 kg/m2, P = .006) and lived further away from site of surgery (34 vs 96 miles, P = .02). No significant differences were observed in receipt of neoadjuvant chemotherapy, laparoscopic surgery, or number of lymph nodes removed during cystectomy between ethnicity groups. However, Hispanics were less likely than non-Hispanics to receive a continent urinary diversion on multivariable analysis (odds ratio 0.30, 95% confidence interval 0.10 - 0.92, P = .03). CONCLUSION: Disparity exists in the delivery of continent urinary diversions for Hispanic patients undergoing radical cystectomy for bladder cancer. Further investigation is needed to determine the potential causes for this disparity in care delivered.
