Increasing Importance of Ethics in Surgical Decision Making

Cutaneous melanoma in older patients

BACKGROUND

In industrialized countries, the aging population is steadily rising. The incidence of cutaneous malignant melanoma (CMM) is highest in old people. This study focuses on the clinicopathological profile of CMM and indicators of diagnostic-therapeutic performance in older patients.

METHODS

This retrospective population-based cohort study included 1,368 incident CMM, as recorded in 2017 by the Regional Veneto Cancer Registry (Northeast Italy). Older subjects were defined as ≥ 80, old as 65-79, and adults as < 65 years of age. The strength of association between pairs of variables was tested by Cramer's-V. Using age groups as the dependent variable, ordered logistic regression was fitted using the clinicopathological CMM profiles as covariates. In each of the three age-groups, the indicators of clinical performance were computed using the Clopper-Pearson exact method.

RESULTS

Compared to patients aged younger than 80 years (1,187), CMM in older patients (181; 13.2%) featured different CMM topography, a higher prevalence of ulcers (43.3% versus 12.7%; p < 0.001), a higher Breslow index (p < 0.001), a lower prevalence of tumor-infiltrating lymphocytes (64.4% versus 76.5%, p < 0.01), and a more advanced pTNM stage at clinical presentation (p < 0.001). Elderly patients with a positive sentinel-lymph node less frequently underwent sentinel- lymph node biopsy and lymphadenectomy (60.0% versus 94.2%, and 44.4% versus 85.5%, respectively; p < 0.001).

CONCLUSIONS

In older CMM patients, the clinicopathological presentation of CMM shows a distinctive profile. The present results provide critical information to optimize secondary prevention strategies and refine diagnostic-therapeutic procedures tailored to older patients.

Ethical issues in the operating room: A scoping review

BACKGROUND

For the patients receiving care in the operating room, it emphasizes that the ethical behavior and attitude of health professionals should be aligned with patients' basic human rights. Surgical ethics may provide an ethical alternative in a specific operating room context. However, it is unclear how actively research is being conducted in this regard.

AIM

This study determines the direction of future research by identifying ethical issues experienced in the operating room.

METHOD

This scoping review is based on the methodological framework suggested by Arksey and O'Malley in 2005. PubMed, CINAHL, EMBASE, WOS, Cochrane, KISS, and KMbase databases were searched from January 2012 to May 2022. Two researchers independently screened the searched articles by reviewing the titles, abstracts, and full texts. Consequently, 19 studies were selected.

FINDINGS

Five categories were identified: Professional ethics, Organizational ethics, Patients' rights, Patient safety, and Allocating resources. The derived categories covered all the same content as the International Council of Nurses' (ICN) code of ethics, with the exception of one element, that is, global health.

CONCLUSIONS

This study highlights ethical issues in the operating theatre and emphasizes the need for individual and organizational strategies aligned with the ICN code of ethics. Future research should cover a wider range of issues, employ diverse perspectives and methodologies, and enhance ethical practices to improve understanding and ethical practices in the field.

Ethical considerations during a pioneering surgical procedure: porcine cardiac xenotransplantation

Preclinical advances in life-sustaining porcine cardiac xenotransplantation from donor pigs to baboons have paved the way for the performance of porcine cardiac xenotransplantation in a human. This procedure was performed with emergency use authorisation granted by the United States Food and Drug Administration under the umbrella of investigational new drug use on compassionate grounds. The patient was denied candidacy for durable mechanical circulatory support and heart transplantation as a result of non-adherence to medical advice.

Successful porcine cardiac xenotransplantation in humans will significantly increase the availability of potential donor organs for long-term management of end-stage heart failure. Human porcine cardiac xenotransplantation is associated with ethical conflicts encompassing multiple ethical principles which are not mutually exclusive and are sometimes conflicting. This article focuses on some of the ethical conflicts encountered in relation to the use of mechanical circulatory support, pretransplant evaluation, shared decision making during informed consent, infectious disease risk, preclinical and clinical testing, and the role of regulatory bodies during performance of the first human porcine cardiac xenotransplantation.

An increase in human trials of xenotransplantation procedures is imminent. Potential ethical conflicts associated with xenotransplantation should be addressed appropriately.
