This study aims to evaluate the epidemiology of potential drug interactions in terminally-ill cancer patients receiving exclusively supportive care. In this cross-sectional study, during a 6-month follow-up, we considered the medical record of terminally-ill cancer patients referred to palliative care at the cancer center in Isfahan, Iran. Potential drug-drug interactions (DDIs) were assessed by Lexi-Interact ver.1.1 online software. During the study period, 133 terminally-ill cancer patients were recruited. We detected 1678 DDIs with moderate or major severity levels. Among them, 330, 219, 32, 1075, and 51 interactions were categorized in B, C, D, and X drug interactions categories, respectively. One hundred and twenty-two patients (91.73%) encountered at least one potential drug-drug interaction during the end of life care. Mechanistically, most drug-drug interactions (64.5%) were pharmacodynamics. The most frequent pharmacological class of drugs responsible for DDIs were quetiapine (91 cases), oxycodone (87 cases), and sertraline (55 cases). Interaction between oxycodone and sertraline was found to be in the top 10 detected DDIs (13.7%). Our results showed that potentially moderate or major drug-drug interactions often occur among terminally-ill cancer patients and the clinical significance of DDIs should be considered meticulously in the palliative care cancer setting.

Background: Patients with multiple myeloma (MM) have compromised immune systems due to the nature of the malignancy and anticancer treatments. This study aims to report the effects of Bortezomib-containing chemotherapy regimens on the severity and mortality of MM patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). Method: This retrospective cohort study enrolled MM patients presenting with coronavirus disease 2019 (COVID-19) infection referred to Omid Hospital. Patients were divided into two groups based on whether they received any chemotherapy regimens containing Bortezomib within the last 90 days of admission or not. Clinical and laboratory characteristics, severity, and outcomes of both groups were reported and compared. Results: Among 48 patients with MM diagnosed with COVID-19 (63% male; median age 66), 33 received chemotherapy. The most common symptoms were fever, cough, and dyspnea, and there was no significant difference between the groups. Only D-dimer had a significant difference in laboratory tests (P = 0.03) and was higher in the chemotherapy group. There was no significant relationship between chemotherapy and severity (risk ratio (RR) = 1.17; 95% confidence interval (CI): 0.37 to 3.71; P = 0.79) or chemotherapy and mortality (RR = 1.00; 95% CI: 0.39 to 2.61; P = 0.99), even after adjusting for baseline C-reactive protein and white blood cell counts. Conclusion: Our study showed that receiving Bortezomib-containing chemotherapy regimens did not worsen the symptoms and prognosis of MM patients infected with COVID-19. However, further studies with larger sample sizes and longer follow-up times are needed to provide better evidence on this subject. [ABSTRACT FROM AUTHOR]

Background: Hand-foot syndrome (HFS) is a prevalent skin reaction to cytotoxic systemic therapy, mainly Capecitabine. The present study aimed to determine etiologies of HFS in addition to its prevention in colorectal cancer patients with Capecitabine-containing chemotherapy regimen. Method: In this randomized double-blinded study, we recruited 66 eligible patients. The first 33 patients received 25 mg captopril twice daily, while the other 33 were given two placebo tablets. Results: All the patients were assessable for safety and efficacy. Captopril demonstrated a favorable safety profile. The participants in the two groups did not have any significant differences in terms of the median age and the level of hemoglobin (P = 0.45, P = 0.06, respectively). However, the CEA tumor marker was significantly higher in those with HFS (P < 0.05). The incidence of HFS in men and women were 8 (18.6%) and 3 (13%) cases, respectively, and the patients' sex did not affect the incidence of this syndrome (P = 0.73). Furthermore, according to the stage of colorectal cancer, the difference between the two groups was significant (P < 0.05). Meanwhile, there were no significant differences concerning the grade of colorectal cancer (P = 0.2). Conclusion: The results herein revealed that administration of captopril in colorectal cancer patients with Capecitabine-containing chemotherapy regimen reduced the symptoms and incidence of HFS. On the other hand, CEA tumor marker and the stage of colorectal cancer were in correlation with incidence of HFS. [ABSTRACT FROM AUTHOR]

Background: Patients with cancer are at an increased risk of mortality from COVID-19 infection. So, they are prioritized for vaccination. However, there is limited data about the immunogenicity, safety, and effectiveness of inactivated vaccines in preventing COVID-19 infection, hospitalization, and mortality in patients with cancer. Objectives: This study aimed to report the clinical characteristics of patients who had a positive PCR test after being fully vaccinated with the Sinopharm BBIBP-CorV Vaccine. Methods: In this retrospective study, the data of patients with cancer were extracted from the electronic health records of a cancer center in Isfahan, Iran. All COVID-19 data from Isfahan province also was collected by Isfahan COVID-19 Registry (I-CORE). We described the clinical characteristics of patients with cancer who have a positive test more than 14 days after the second dose. Results: Two hundred twenty-two patients with cancer had at least one positive PCR test after the start of the COVID-19 vaccination. Of these, 9 (4.1%) breakthrough infections have occurred. Six (67%) of them had hematological malignancies. Six (67%) were hospitalized and 3 (33%) patients died. Two of them had recent chemotherapy and have hematological malignancies. Conclusions: Vaccination is a good way to protect the population from COVID-19 complications and mortality, but it should be considered that fully-vaccinated patients with cancer are at risk of severe outcomes. Nevertheless, prioritizing cancer patients, especially those with hematological malignancies, or receiving chemotherapies for booster vaccines and studying the effectiveness of each COVID-19 vaccine for patients with cancer should be considered.

Aim and objectives: The present study aims at exploring oncology nurses' perceptions regarding work‐related stressors. Background: Oncology nurses work in an environment with a high degree of stress, which can negatively affect their health. There is limited research on work‐related stressors from the oncology nurses' perspective. Design: Qualitative descriptive study. Methods: Fifty‐two oncology nurses were selected purposefully from eight cancer treatment centres in different cities of Iran. Data were collected through semi‐structured interviews and analysed using conventional content analysis. The COREQ checklist was used to document the report of the study. Results: The extracted contents were classified into four main categories. The first category involved personal ability with two subcategories (person‐job fit and psychological competencies). The second category included physical environment arrangements with two subcategories (physical working conditions and equipment and facilities). The third category involved psychosocial safety in the workplace with four subcategories (creating a safe work environment, overcoming the challenges of providing care to cancer patients, work/life balance and social recognition of the nursing status). The fourth category holds an organisational context with four subcategories (organisational support, interpersonal relations, justice at work and human resources). Conclusion: It is necessary to find measures attenuating work‐related stresses in oncology nurses. These measures should be in line with developing personal abilities in nurses and creating a safe environment in terms of optimising physical, psychosocial and organisational conditions. It is also important to develop programmes protecting the oncology nurses' occupational health. Relevance to clinical practice: The results of this study can help improve nursing work conditions, attenuate work‐related stresses in nurses and introduce efficient interventions reducing occupational stressors.

Background: Cancer patients, as a highly vulnerable population, are receiving a great deal of attention in the current crisis of coronavirus 2019 (COVID-19). To date, shreds of evidence are not sufficient to the description of COVID-19 outcomes in patients with cancer. This study was performed to evaluate the demographic and clinical characteristics and subsequent outcomes of COVID-19 in cancer patients. Materials and Methods: A hospital-based study was conducted involving 66 cancer patients with a confirmed diagnosis of COVID-19 from January 15, 2020, to December 21, 2020, in Isfahan, Iran. The clinical information was collected by interview and medical records. The statistical analyses were performed to describe categorical variables as well as mean, standard deviation, median, and the interquartile range for quantitative variables. Results: In our study, 66 cancer patients with confirmed COVID-19 (age: 17–97 years; 50% female) were included. Leukemia and bone marrow cancer with a frequency of 25.7% were the most common types of cancer among them. Cancer patients mostly complained of fever, cough and fatigue, and shortness of breath. Among 76.9% of patients discharged from the hospital with relative recovery, 23% died; the most common cause of death was acute respiratory distress syndrome. Age, gender, and type of cancer did not affect cancer mortality. COVID-19 had no potential effect to increase the risk of side effects of anticancer therapies. Conclusion: The results of our studies revealed that cancer is an important risk factor for the higher rate of mortality in patients with COVID-19. These findings could help physicians for the management, treatment, and supportive care of COVID-19 cancer patients. [ABSTRACT FROM AUTHOR]
