The impact of COVID-19 on cancer patients, their carers and oncology health professionals: A qualitative study

OBJECTIVE

Cancer patients, carers and oncology health professionals have been impacted by the COVID-19 pandemic in many ways, but their experiences and psychosocial responses to the pandemic are still being explored. This study aimed to document the experience of Australians living with cancer, family carers, and Oncology health professionals (HPs) when COVID-19 first emerged.

METHODS

In this qualitative study, participants (cancer patients currently receiving treatment, family carers and HPs) completed a semi-structured interview exploring their experiences of COVID-19 and the impact it had on cancer care. Participants also completed the Hospital Anxiety and Depression Scale (patients) and the Depression, Anxiety and Stress Scale (carers and HPs) to assess emotional morbidity. Thematic analysis was undertaken on qualitative data.

RESULTS

32 patients, 16 carers and 29 HPs participated. Qualitative analysis yielded three shared themes: fear and death anxiety, isolation, and uncertainty. For HPs, uncertainty incorporated the potential for moral distress and work-stress. Patients and carers scoring high on anxiety/depression measures were more likely to have advanced disease, expressed greater death anxiety, talked about taking more extreme precautionary measures, and felt more impacted by isolation.

CONCLUSION

Cancer and COVID-19 can have compounding psychological impacts on all those receiving or giving care.

PRACTICE IMPLICATIONS

Screening for distress in patients, and burnout in HPs, is recommended. Increased compassionate access and provision of creative alternatives to face-to-face support are warrented.

Cross-national interrater agreement on the clinical diagnostic criteria for dementia. WHO-PRA Age-Associated Dementia Working Group, WHO-Program for Research on Aging, Health of Elderly Program

We assessed the interobserver agreement on the clinical diagnosis of dementia syndrome and dementia subtypes as part of a cross-national project on the prevalence of dementia. Fourteen clinicians from the participating countries (Canada, Chile, Malta, Nigeria, Spain, and the United States) independently assessed the diagnosis of 51 patients whose clinical information was in standard records written in English. We used the DSM-III-R and ICD-10 criteria for dementia syndrome, the NINCDS-ADRDA criteria for Alzheimer's disease (AD), and the ICD-10 criteria for other dementing diseases, and measured interobserver agreement. We found comparable levels of agreement on the diagnosis of dementia using the DSM-III-R (kappa = 0.67) as well as the ICD-10 criteria (kappa = 0.69). Cognitive impairment without dementia was a major source of disagreement (kappa = 0.10). The kappa values were 0.58 for probable AD, 0.12 for possible AD, and rose to 0.72 when the two categories were merged. The interrater reproducibility of the diagnosis of vascular dementia was 0.66 in terms of kappa index; the diagnoses of other dementing disorders as a whole reached a kappa value of 0.40. This study suggests that clinicians from different cultures and medical traditions can use the DSM-III-R and the ICD-10 criteria for dementia effectively and thus reliably identify dementia cases in cross-national research. The interrater agreement on the diagnosis of dementia might be improved if clear-cut guidelines in the definition of cognitive impairment are provided. To improve the reliability of AD diagnosis in epidemiologic studies, we suggest that the NINCDS-ADRDA "probable" and "possible" categories be merged.

Prophylaxis of heart transplant rejection with either antithymocyte globulin-, Minnesota antilymphocyte globulin-, or an OKT3-based protocol

We compared an equine antithymocyte globulin (ATGAM)-based protocol with a Minnesota antilymphocyte globulin (MALG)-based protocol and a murine monoclonal CD-3 (OKT-)-based protocol in 3 groups of heart transplant (HT) recipients. Thirty-four recipients received a four-day course of ATGAM. Thirty HT recipients received a 14-day course of OKT3. Fifteen HT recipients received MALG for an average of 10 days. The ATGAM group received cyclosporine beginning preoperatively, while the OKT3 and MALG groups received CyA beginning on post-transplant day 4. All three groups received identical azathioprine and similar steroid therapy. The 3 groups were similar in age, donor/recipient HLA mismatches, and donor/recipient gender mismatches. The MALG and OKT3 groups had 20% and 17% females, respectively, while the ATG group had 41% (p < 0.05). Average follow-up exceeded 14 months for each group. The ATGAM group received a higher dose of CyA during "induction" therapy than the OKT3 and MALG groups, and experienced a greater rise in post-transplant serum creatinine levels. We found no difference between the 3 groups in: preoperative creatinine levels, one-year post-transplant creatinine levels, number of patients who could be successfully "weaned" from steroids, or one-year survival. Other data are tabulated as episodes/patient: [table: see text] We conclude that ATG plus preoperative CyA is superior for rejection prophylaxis following heart transplantation when compared with either MALG plus postoperative CyA or OKT3 plus postoperative CyA.

In vitro recombination of bacteriophage T7 DNA: further characterization of the reaction using plasmid DNA

We have used a plasmid which contains a cloned fragment of T7 DNA to study the properties of general recombination of phage T7 in vitro. It was shown that T7-infected cell extracts promote recombination by the exchange of double strands of DNA. While both products of these double-strand exchanges were detected, we were unable to show that they were formed during a single recombination event.
