Results of the ECHO (Eating habits CHanges in Oncologic patients) Survey: An Italian Cross-Sectional Multicentric Study to Explore Dietary Changes and Dietary Supplement Use, in Breast Cancer Survivors

The role of a healthy diet in cancer prevention is well recognized. Recent data indicate that following the same advices can also improve cancer survivors’ quality of life. Breast cancer (BC) patients are commonly concerned about diet and nutrition and frequently express the need to obtain health-related information and the will to change their diet and lifestyle. Hence, be aware of survivors’ dietary changes and information needs is crucial for healthcare professionals to guide them toward optimal lifestyle choices. In order to investigate eating habits changes in a BC survivors’ population, we conceived the cross-sectional multicentric study ECHO (Eating habits CHanges in Oncologic patients) Survey. Data were collected from 684 patients, diagnosed with invasive breast cancer, in order to investigate their changes in food consumption, use of supplements, or the beginning of a specific diet, after BC diagnosis. We also examined the sources of information used and if any modification in their diets was reported to the oncologist. We primarily observed that patients increased their consumption of vegetables, pulses, nuts, fruits, wholemeal bread/pasta, grains and fish; while decreasing red and processed meat, refined bread/pasta, baked good and animal fat consumption. Survivors also reported the use of dietary supplements, mainly vitamins, aimed at counteracting therapies’ side effects. Changes in nutritional habits were often adopted without asking or informing the oncologist. Despite BC survivors made some positive changes in their nutritional habits, those modifications were mostly pursued by less than half of them, while the majority of patients consumed nutritional supplements after diagnosis. These results, as well as the failure to communicate with the physicians, reinforce the need to both improve the patient-healthcare professional relationship and to develop tailored nutrition counselling and intervention programs for cancer survivors.

The impact of COVID-19 pandemic on oncology workload: The experience of an Italian Reference Cancer Center

e13520

Background: Since its outbreak in January 2020, the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic dramatically affected health systems worldwide and a prompt realignment of clinical activities had to be thought. International Oncology guidelines recommended that routine oncology care continued to be delivered, ensuring triage procedures to prevent COVID-19 diffusion alongside treatments prioritization. Aim of this study was to assess the variation of activity volumes due to COVID-19 pandemic in the Oncology Department of the Academic Reference Cancer Center of Udine, Italy. Methods: We extracted activity volumes from the electronic “Data Warehouse” accountability system and compared activity in 2020 with historical activity in 2019. We then narrowed the analysis to the peak of COVID-19 pandemic, comparing data of a four-months period (February-May 2020 vs 2019). In accordance with the Italian Association of Medical Oncology guidelines, the activities analyzed included: new patients referrals, first consultations, new therapy assignments, treatment prescriptions and therapy administrations, disease re-assessments, follow-up visits, tele-examinations, unplanned visits and ward discharges. Results: Overall, throughout COVID-19 pandemic a negligible reduction in the number of first consultations (-5%) and new patients referrals to our Oncology Department (-10%) was detected. Of note, a significant reduction in the number of unplanned oncologic visits was observed (-23%). The replacement of follow up visits with telephonic interviews with the interpretation of laboratory and radiologic examinations (tele-examinations) led to a substantial reduction in follow-up visits throughout 2020 (-25%). Conversely, treatment-related activities, including new therapy assignments (+1%), treatment prescriptions and therapy administrations (+2% and +3%, respectively), confirmed the increasing trend of the previous year. Interestingly, similar trends were observed in the four-months peak period with a substantially higher decrease in follow-up visits in 2020 vs 2019 (-51%), whereas treatment-related activities remained stable. Conclusions: In the context of COVID-19 pandemic, our Oncology Department maintained stable performances on critical oncology activities. Strict triage procedures, serial swabs for patients and healthcare professionals and strategic follow-up visits remodulation were crucial. Notwithstanding the significant decrease in cancer treatments observed in several published reports, our experience demonstrates that the reorganization of oncology departments during a global pandemic is feasible and it should be pursued to preserve patients’ safety without compromising the continuum of care.

Feasibility and Predictive Performance of a Triage System for Patients with Cancer During the COVID-19 Pandemic

BACKGROUND

Triage procedures have been implemented to limit hospital access and minimize infection risk among patients with cancer during the coronavirus disease (COVID-19) outbreak. In the absence of prospective evidence, we aimed to evaluate the predictive performance of a triage system in the oncological setting.

MATERIALS AND METHODS

This retrospective cohort study analyzes hospital admissions to the oncology and hematology department of Udine, Italy, during the COVID-19 pandemic (March 30 to April 30, 2020). A total of 3,923 triage procedures were performed, and data of 1,363 individual patients were reviewed.

RESULTS

A self-report triage questionnaire identified 6% of triage-positive procedures, with a sensitivity of 66.7% (95% confidence interval [CI], 43.0%-85.4%), a specificity of 94.3% (95% CI, 93.5%-95.0%), and a positive predictive value of 5.9% (95% CI, 4.3%-8.0%) for the identification of patients who were not admitted to the hospital after medical review. Patients with thoracic cancer (odds ratio [OR], 1.69; 95% CI, 1.13-2.53, p = .01), younger age (OR, 1.52; 95% CI, 1.15-2.01, p < .01), and body temperature at admission ≥37°C (OR, 9.52; 95% CI, 5.44-16.6, p < .0001) had increased risk of positive triage. Direct hospital access was warranted to 93.5% of cases, a further 6% was accepted after medical evaluation, whereas 0.5% was refused at admission.

CONCLUSION

A self-report questionnaire has a low positive predictive value to triage patients with cancer and suspected severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) symptoms. Differential diagnosis with tumor- or treatment-related symptoms is always required to avoid unnecessary treatment delays. Body temperature measurement improves the triage process's overall sensitivity, and widespread SARS-CoV-2 testing should be implemented to identify asymptomatic carriers.

IMPLICATIONS FOR PRACTICE

This is the first study to provide data on the predictive performance of a triage system in the oncological setting during the coronavirus disease outbreak. A questionnaire-based triage has a low positive predictive value to triage patients with cancer and suspected severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) symptoms, and a differential diagnosis with tumor- or treatment-related symptoms is mandatory to avoid unnecessary treatment delays. Consequently, adequate recourses should be reallocated for a triage implementation in the oncological setting. Of note, body temperature measurement improves the overall sensitivity of the triage process, and widespread testing for SARS-CoV-2 infection should be implemented to identify asymptomatic carriers.

When and how clinical nurses adjust nursing care at the end-of-life among patients with cancer: Findings from multiple focus groups

PURPOSE

Defining patients as 'terminally-ill' may be difficult. Therefore, determining when to shift the goal of care from curative to comfort care may be extremely challenging. The aim of this study was to merge when and how Registered Nurses (RNs) and Nurses' Assistants (NAs) adjust end-of-life care to pursue patient comfort at the end of their lives.

METHODS

A descriptive qualitative study based on multiple focus groups was performed in 2017 according to the COnsolidated criteria for REporting Qualitative research guidelines. In all, 25 RNs and 16 NAs across seven north-east Italian facilities that provide end-of-life care, voluntarily participated in the study. Each focus group was conducted following the same interview guide with open-ended questions, and was audiotaped. A thematic analysis was applied to interview transcripts.

RESULTS

The process of nursing care plan adjustment is based upon two main themes, around 'when' and 'how' to adjust it. Regarding when, 'Detecting the turning point', and 'Being ready to change continuously until the end' emerged as the main sub-themes. Regarding how, 'Weighing harms and benefits of nursing care interventions'; 'Advocating for patients' wishes', 'Sharing the adjustments inside the team at different levels', 'Involving family in the adjustments of nursing care'; and 'Allowing care to move away from evidence-based practice' were the sub-themes emerged.

CONCLUSIONS

Shedding light on the implicit decisional processes that inform care adjustments and the implementation of related strategies is essential to improve the quality of end-of-life care given that an early detection of the terminal phase has been reported to result in changes of care improving outcomes.

What to do in an oncology department to face the new COVID-19 era challenges?

Italy was the first European country to be hit by COVID-19 pandemic. As a consequence, Italian oncologists had to guarantee essential treatments although minimizing exposure to the virus, and accidental infection, of patients and healthcare professionals. As Department of Medical Oncology of the University Hospital of Udine, in this short report, we describe the measures that we have taken, and gradually updated, since February 26, 2020. All accesses to our Oncology facilities are currently regulated by entrance check-points where patients are screened for infections following dedicated algorithms. Up to date, after 6 weeks of systematic execution of swabs no physician, nurse or other individual of the staff has been found positive to COVID-19. Only one patient admitted for therapy has been identified as COVID-19 positive. The aim of our work is to propose a model, made up of a set of operative procedures, that may be adopted by all the oncologists that daily struggle to guarantee safety and care in Oncology during this COVID-19 emergency.

Control of enteric neuromuscular functions by purinergic A(3) receptors in normal rat distal colon and experimental bowel inflammation

BACKGROUND AND PURPOSE

Adenosine A(3) receptors mediate beneficial effects in experimental colitis, but their involvement in enteric neuromuscular functions during bowel inflammation is undetermined. This study investigated the regulatory role of A(3) receptors on colonic motility in the presence of experimental colitis.

EXPERIMENTAL APPROACH

Colitis was induced in rats by 2,4-dinitrobenzenesulfonic acid. A(3) receptors and adenosine deaminase (ADA, adenosine catabolic enzyme) mRNA were examined by RT-PCR. Tissue distribution of A(3) receptors was detected by confocal immunofluorescence. The effects of 2,3-ethyl-4,5-dipropyl-6-phenylpyridine-3-thiocarboxylate-5-carboxylate (MRS1523) (MRS, A(3) receptor antagonist), 2-chloro-N(6) -(3-iodobenzyl)-adenosine-5'-N-methyluronamide (2Cl-IB-MECA) (CIB, A(3) receptor agonist), dipyridamole (DIP, adenosine transport inhibitor) and ADA were assayed on contractile responses evoked by electrical stimulation (ES) or carbachol in colonic longitudinal muscle preparations (LMP).

KEY RESULTS

RT-PCR showed A(3) receptors and ADA mRNA in normal colon and their increased level in inflamed tissues. Immunofluorescence showed a predominant distribution of A(3) receptors in normal myenteric ganglia and an increased density during colitis. MRS enhanced ES-induced cholinergic contractions in normal LMP, but was less effective in inflamed tissues. After pretreatment with dipyridamole plus ADA, to reduce extracellular adenosine, CIB decreased cholinergic motor responses of normal LMP to ES, with enhanced efficacy in inflamed LMP. A(3) receptor ligands did not affect carbachol-induced contractions in LMP from normal or inflamed colon.

CONCLUSIONS AND IMPLICATIONS

Normally, adenosine modulated colonic cholinergic motility via activation of A(3) receptors in the myenteric plexus. A(3) receptor-mediated tonic inhibitory control by adenosine was impaired in inflamed bowel, despite increased density of functioning and pharmacologically recruitable A(3) receptors.

A reasonable methodology to estimate the relationship between workload and human resources demand in a cancer unit

e17555

Background: Costs of cancer care account for a growing proportion of European health care spending. Despite the rising price of new cancer drugs draws the attention of medical oncologists and decision makers, personnel spending takes the largest share of health care costs. Nonetheless, few data exist about the relationship between workload and human resources demand in a cancer unit. Here we describe an empirical model to determine staffing requirements according to the annual number of patients. Methods: The Department of Oncology at the University Hospital of Udine, Italy, is a computerized Unit within the regional cancer network taking care of about 1,500 pts/year. Each clinical episode is recorded on a centralized database. Standard time limits are set for different types of consultation. We queried the database to obtain the total number of consultations for every pt taken charge of by the Unit during 2006. Considering both the time scheduled for each type of visit and the number of yearly working hours per employee, we could reach a reasonable estimate of the annual physician and nurse hours per pt and of the number of needed personnel. Results: In 2006, each case generated an average of 16 clinical evaluations, with small differences among breast, lung and colorectal cancer. Corresponding physician- and nurse-time per pt was of 8 and 16 hours, respectively. For the first year - in Units with a mean number of 1,500 pts/year - this translates into a global amount of about 12,000 physician- and 24,000 nurse-hours and a needed number of 7 physicians and 13 nurses, respectively. In the second year, the same cases induced a mean of 4.5 consultations; using a similar approach, the demand for additional time and resources could be estimated as well. Conclusions: A preliminary assessment of the time required for different types of consultation, together with a centralized recording of each clinical episode, allows a reasoned estimate of needed time and personnel resources, thus providing a simple tool to determine the total staff expenditure of a cancer unit.

Cytochrome P450 and radiopharmaceutical metabolism

Positron emission tomography (PET) is a powerful non-invasive probe to investigate human physiology. A large number of radiotracers have been studied as imaging agents, but only a few have found clinical applications in pharmacology. A potential radiopharmaceutical is designed with very specific physiochemical characteristics, but, generally, less attention is paid to its adsorption, distribution, metabolism, and excretion properties, especially metabolism. Understanding the metabolic fate of radiopharmaceutical probes is essential for an accurate analysis and interpretation of PET measurements. The inherent inability of PET to differentiate between a parent compound and its metabolites confounds the interpretation of images and may impact the identification of the pathologically induced biochemical changes under investigation. Cytochrome P450 plays a major role in mammalian xenobiotic biotransformation and many in vitro methods are available to study and predict drug metabolism. The purpose of this review is to highlight the existing in vitro techniques available to investigate the biotransformation of xenobiotics in a fashion analogous to small molecule drug discovery. The aim is to facilitate the development and validation phases of PET tracers during preclinical evaluation. Emphasis is placed also on describing how cross species comparisons are essential in establishing appropriate translational pharmacology. Procedures of analysis (tandem liquid chromatography-mass spectrometry), typically used for studying the metabolism of drugs, are proposed as quick and accurate tools for the determination of a radiopharmaceutical's metabolic stability at the tracer level.

[The surveillance system of decubital lesions of the University Polyclinic in Udine: results of an incidence study]

A retrospective study of the incidence of pressure sores was one of the principal component of the ad hoc program of surveillance, prevention and treatment of pressure sores started in 1996 at University Hospital of Udine. Data were collected from the nursing records of patients defined at risk according to the Waterlow scale and admitted during 1998-99. Aims of the study were to quantify the number of patients who developed a pressure sore while in hospital and their risk level; stage of the lesions; to qualify the main risk factors and the management strategies adopted (i.e. mattresses, medications). Overall, 151 subjects (20.7% of those recruited) developed a pressure sore the greatest majority (96%) were classified as transient and reactive redness or superficial sore, while 14 patients (4%) developed a severe sore. For 50.4% of the lesions a regression to a lower risk level or healing were documented.

Ozonation of Reactive Blue 81 in the bubble column

The decolourisation process of the Reactive Blue 81 was carried out in a laboratory bubble column reactor with inner diameter 110 mm and working height 550 mm, equipped with a porous glass ozone diffuser (diameter 50 mm). A model of ozone absorption with the chemical reaction in the liquid phase was employed. It was found that the decolourisation proceeds in the fast pseudo first-order regime. The average value of the enhancement factor was calculated from the experimental results and compared with those calculated according to the theory of mass transfer with a second-order chemical reaction. In order to determine the intrinsic kinetics of ozonation, a stopped-flow technique was employed. The rate constant of the dyestuff reaction with ozone was determined as equal to 4.5 x 10(7) mol/(dm3.s).
