Formation of intravenous catheter-related thrombosis leads to central venous stenosis in patients requiring renal replacement therapy or chemotherapy infusion, yet the triggering or mechanisms remain unclear, especially in patients without symptoms of infection. In this study, we found that neutrophil extracellular traps (NETs) could be detected in the fibrin sheaths from dialysis patients without clinical manifestations of infection. Confocal microscopy revealed bacteria imbedded in NETs in the fibrin sheaths. Thirty-nine of 50 (78%) fibrin sheath specimens contained bacteria detectable by 16S ribosomal RNA genome typing with a predominance of Staphylococcus aureus (69%). In rat models, transient bacteremia of S. aureus induced NETs in enlarged fibrin sheaths, and treatment with DNase I alone significantly reduced both NET and fibrin sheath formation surrounding the catheter. Therefore, transient bacteremia could be a silent trigger that induces NET-related immunothrombosis enhancing catheter-related central venous stenosis.

Over the last decade, chemotherapy treatments have dramatically shifted to outpatient services such that nearly 90% of all infusions are now administered outpatient. This shift has challenged oncology clinics to make chemotherapy treatment as widely available as possible while attempting to treat all patients within a fixed period of time. Historical data from a Veterans Affairs chemotherapy clinic in the United States and staff input informed a discrete event simulation model of the clinic. The case study examines the impact of altering the current schedule, where all patients arrive at 8:00 AM, to a schedule that assigns patients to two or three different appointment times based on the expected length of their chemotherapy infusion. The results identify multiple scheduling policies that could be easily implemented with the best solutions reducing both average patient waiting time and average nurse overtime requirements.

Background: Pembrolizumab is a monoclonal antibody-based chemotherapy infusion, recently approved for unresectable or metastatic solid tumors with certain genetic anomalies. Discussion: Pembrolizumab is an IV infusion therapy for treating non-surgical or metastatic melanoma and non-small cell lung cancer. Multiple cardiac complications have been related to this drug, the mechanism is not precise, but a possibility is immune events involving the cytotoxic T-cell resulting in fibrosis of the cardiac cells. Conclusion: New oncologic medications have emerged with a potential reversible or irreversible cytotoxicity, including inflammation, dysfunction, or apoptosis that could represent a life-threatening condition. There is not enough data to establish proper therapy to avoid cardiotoxicity on monoclonal therapies, but an early approach and immunosuppressive therapy are thought to improve the outcome.

BackgroundPediatric neurointervention is challenged by the appropriateness of adult catheters and devices. This multicenter report on the smallest groin access sheaths offers technical notes and clinical outcomes in the pediatric neurointerventional population.MethodsAll pediatric neurointerventional cases from 2019 to 2021 were reviewed for use of a 3.3F Pediavascular or a 4F Merit Prelude Ideal low profile sheath. Hospital records were reviewed for complications and technical notes and compared with arterial groin access with the 4F Terumo Pinnacle in infants less than 1 year old, before the low profile sheaths at one author’s institution were introduced.ResultsFrom January 1, 2019 to March 31, 2021 there were 347 procedures performed at Boston Children’s Hospital and University of Wisconsin. Forty-four procedures in 26 patients were identified in which a 3.3F (38 cases, 20 patients) or 4F (6 cases, 6 patients) sheath was used. The average age was 2.2 years (1.5 days to 18 years). Retinoblastoma intra-arterial chemotherapy infusion (18 of 44) was the most common indication. The remaining procedures comprised vein of Galen embolization (12), diagnostic cerebral angiography (13), and one preoperative tumor embolization. Morbidity included a groin hematoma and decreased pulses (4.5%). No major groin complications occurred. There was no statistically significant difference compared with the historical cohort (132 procedures), which had seven instances of decreased pulses (5.3%, p>0.05).ConclusionThe 3.3F Pediavascular and 4F Merit Prelude Ideal sheaths are easily incorporated into the pediatric neurointerventionalist’s armamentarium for infants and readily accommodate various microcatheters for distal embolization and catheterization.

Abstract Background The clinical outcomes of drug-eluting beads transarterial chemoembolization (DEB-TACE) with doxorubicin-loaded CalliSpheres® beads for patients with unresectable or recurrent esophageal carcinoma have not been reported. The aim of this study is to study the clinical outcomes of DEB-TACE for patients with unresectable or recurrent esophageal carcinoma. Methods This retrospective study enrolled 21 patients (15 men; mean age 68.7 ± 9.7; range 46–86 years) with unresectable or recurrent esophageal carcinoma received DEB-TACE between July 2017 and September 2020. Patient characteristic data, imaging findings, complications and DEB-TACE procedure were reviewed. The primary endpoints, disease control rate (DCR) and objective response rate (ORR), were calculated. The secondary endpoints were overall survival rate and progression-free survival (PFS). Results Twenty-two sessions of DEB-TACE were performed in 21 patients. The technical success rate was 100%; without sever adverse events or procedure-related deaths. All patients received transarterial chemotherapy infusion with raltitrexed or oxaliplatin. The median follow-up period was 3.6 months (interquartile range, IQR 1.5–9.4 months). ORR and DCR were 42.9 and 85.7%, 28.6 and 71.4%, 20.0 and 40.0% respectively at 1-, 3-, and 6-months after DEB-TACE. The median PFS was 6.0 months, and the 3-, 6- and 12-month PFS rates were 68.2%, 45.5 and 0.0%, respectively. The median overall survival was 9.4 months, and the 3-, 6- and 12-month overall survival rates were 75.5%, 55.0 and 13.8%, respectively. Conclusions To our knowledge, this is the first study reports outcomes of DEB-TACE with doxorubicin-loaded CallSpheres bead treatment in the management of patients with unresectable or recurrent esophageal carcinoma. According to our results, this is a safe and feasible treatment modality that may be considered among the options for the treatment of these patients.

BACKGROUND Current research into virtual reality (VR) use during chemotherapy shows that it can be an effective distraction intervention. There is limited research in adult patients and how VR can be sustainably implemented in healthcare organisations. This study explored the feasibility and acceptability of VR for adult patients undergoing chemotherapy. OBJECTIVE This study aimed to explore the feasibility and acceptability of using virtual reality for adult patients undergoing chemotherapy, and the factors that would enable sustained use of VR during chemotherapy in healthcare organisations. METHODS Participants undergoing chemotherapy were recruited to participate in a VR intervention during chemotherapy infusion. Participants were observed during the session and completed a post-intervention survey. Each participant was invited to participate in a semi-structured interview about their experience. RESULTS A total of 18 patients participated in the study, of whom five participated in semi-structured interviews. Findings indicated that the use of VR was acceptable for patients undergoing chemotherapy, and was also feasible. Some participants felt the VR was an effective distraction during chemotherapy infusion, but most still seemed aware of how long their treatment was undertaken for. Although VR was acceptable and feasible to patients, interviews identified a number of barriers to sustained implementation including access to a reliable application library, and impact on staff workloads. CONCLUSIONS VR was acceptable to patients with a diagnosis of cancer undergoing chemotherapy treatment. Patients found VR beneficial for breaking up the monotony of treatment, to provide an additional choice of activity in addition to other recreation, and in some instances as a distraction from treatment itself. There are, however, challenges to address if VR is to be implemented in practice for this patient group.

Abstract Purpose Scalp cooling during chemotherapy infusion to mitigate alopecia for breast cancer patients is becoming widespread; however, studies regarding hair recovery after chemotherapy with scalp cooling are limited. We conducted a prospective study of hair recovery after chemotherapy with scalp cooling. Patients and methods One hundred and seventeen Japanese female breast cancer patients who completed planned (neo)adjuvant chemotherapy using the Paxman Scalp Cooling System for alopecia prevention were evaluated for alopecia prevention in our prospective study. We evaluated their hair recovery 1, 4, 7, 10, and 13 months after chemotherapy. Primary outcomes were grades of alopecia judged by two investigators (objective grades) and patients’ answers to the questionnaire regarding the use of a wig or hat (subjective grades). Results Of 117 patients, 75 completed scalp cooling during the planned chemotherapy cycles (Group A), but 42 discontinued it mostly after the first cycle (Group B). Objective and subjective grades were significantly better in Group A than in Group B throughout 1 year, and at 4 and 7 months after chemotherapy. When we restricted patients to those with objective Grade 3 (hair loss of > 50%) at 1 month, Group A exhibited slightly faster hair recovery based on the objective grades than Group B. There was less persistent alopecia in Group A than in Group B. Conclusions Scalp cooling during chemotherapy infusion for Japanese breast cancer patients increased the rate of hair recovery and had preventive effects against persistent alopecia.

Background: Chemotherapy requires careful dosing and monitoring and is associated with numerous adverse events. There is limited data describing the impact of clinical pharmacists in the chemotherapy ambulatory setting. Objective: This study aimed to evaluate the impact of clinical pharmacy services on patient management in the adult chemotherapy infusion clinics. Methods: This was a 5-year retrospective study that utilized the pharmacy electronic documentation system to determine the type of interventions and adverse drug events (ADEs) reported by the clinical pharmacists in the chemotherapy infusion clinics. Interventions were described based on the type of intervention and medication involved. ADEs were evaluated based on the type of ADE, the suspected medication, and the required management. Results: During the study period, 3,279 interventions and 1,445 ADEs were reported. The most common interventions involved dose adjustments (51%), followed by addition (23%) or discontinuation (21%) of prescribed medications. Carboplatin (20%) and zoledronic acid (14%) were the most common medications that required pharmacist interventions. The most common types of ADEs were hematologic (22%) and infusion-related reactions (20%). Docetaxel was the most common medication associated with ADEs (20%). Among the reported ADEs, most required adding supportive care (44%), followed by adjusting chemotherapy doses (22%). Conclusion: Clinical pharmacy services at the chemotherapy infusion clinics play an important role in optimizing the chemotherapy regimens as well as identifying and managing ADEs. Future studies should be directed to measure the impact of these services on patient outcomes as well as, physicians and pharmacy operational workload and cost savings.
