ABSTRACT

Stimulated by development of reproductive technologies, many current bioethical accounts of parenthood focus on defining parenthood at or around birth. They tend to exclude from their scope some parent-child relationships that develop later in a child's life. In reality, a parent-child relationship can emerge or dissolve over time: the parents of person A as an adolescent or adult may be different to her parents when she is a young child. To address this aspect of parenthood, we propose a new 'mutuality account' of parenthood, grounded in the concept of ontological security. We argue that in most cases a parent-child relationship exists if there is mutual ontological security between the parent and child. We suggest that this mutual ontological security is constituted and sustained by shared frameworks of reality and cohesive personal narratives. Our intention is to broaden the conceptual understanding of parenthood, to include parent-child relationships that do not fall neatly into current bioethical accounts, and to argue against the notion that objective physiological, causal, or social ties are necessary to 'make' a parent.

ABSTRACT

INTRODUCTION: Biliary brushing (BB) cytology has a sensitivity of 15%-65% and specificity approaching 100% for detecting malignancy. Fluorescence in-situ hybridization (FISH) using the UroVysion probe set has been advocated to enhance the detection of malignancies with reported sensitivity of 43%-84%. We sought to evaluate the performance of FISH in BB with equivocal cytology at our institution. MATERIALS AND METHODS: Patients with atypical and suspicious BB with concurrent diagnostic FISH performed at our institution from 2014 to 2021 were identified through a query of our pathology database. FISH (using UroVysion probe set containing centromere enumeration probes to chromosomes 3, 7, and 17) was positive if at least 5 cells demonstrated polysomy. Electronic medical records were reviewed for pathology results and outcomes. Patients were classified malignant if they had positive pathology or documented clinical impression of malignancy and benign if they had negative pathology and/or documented benign clinical course for at least 12 months. RESULTS: We identified 254 equivocal BB (238 atypical/16 suspicious) with concurrent FISH results from 191 patients (105 benign, 86 malignant). 12% (22/191) of patients were FISH positive. Twenty-four percent (21/86) of patients with malignancy had positive FISH but were nonspecific for pancreaticobiliary/ampullary adenocarcinomas. Almost all positive FISH were associated with malignancy (21/22; 95%). There was 1 positive FISH in a patient with primary sclerosing cholangitis who had a benign outcome. CONCLUSIONS: The small number of positive FISH results in BB with equivocal cytology raises the question of the optimal criteria for malignancy. Using only polysomy could result in lower sensitivity.

ABSTRACT

CONTEXT.­: Pleural effusions are common cytologic specimens that can be leveraged to make diagnoses of malignancy that drive appropriate patient management. However, the overlap in morphologic features of reactive mesothelial proliferations, mesotheliomas, and adenocarcinomas can create diagnostic pitfalls in the cytologic evaluation of pleural fluids. OBJECTIVE.­: To review the morphologic spectrum of benign and malignant mesothelial proliferations in pleural effusions, as well as relevant clinicoradiologic contexts and ancillary tests. DATA SOURCES.­: Existing scientific and clinical literature as of January 2023. CONCLUSIONS.­: We can leverage the knowledge of several overlapping morphologic features, clinicoradiologic scenarios, and immunohistochemical studies to enhance the diagnostic accuracy of pleural effusion cytology to appropriately delineate cases of adenocarcinoma, reactive mesothelial proliferation, and mesothelioma. Earlier diagnosis through cytology, particularly in cases of mesothelioma, may positively impact patient treatment options and prognosis.

ABSTRACT

Genomic screening at population scale generates many ethical considerations. One is the normative role that people's preferences should play in determining access to genomic information in screening contexts, particularly information that falls beyond the scope of screening. We expect both that people will express a preference to receive such results and that there will be interest from the professional community in providing them. In this paper, we consider this issue in relation to the just and equitable design of population screening programs like reproductive genetic carrier screening (RGCS). Drawing on a pluralistic public health ethics perspective, we claim that generating and reporting information about genetic variants beyond the scope of the screening program usually lacks clinical, and perhaps personal, utility. There are both pragmatic and ethical reasons to restrict information provision to that which fits the stated purpose of the program.

ABSTRACT

The COVID-19 pandemic has highlighted the risks that can be involved in healthcare work. In this paper, we explore the issue of staff safety in clinical work using the example of personal protective equipment (PPE) in the COVID-19 crisis. We articulate some of the specific ethical challenges around PPE currently being faced by front-line clinicians, and develop an approach to staff safety that involves balancing duty to care and personal well-being. We describe each of these values, and present a decision-making framework that integrates the two. The aim of the framework is to guide the process of balancing these two values when staff safety is at stake, by facilitating ethical reflection and/or decision-making that is systematic, specific and transparent. It provides a structure for individual reflection, collaborative staff discussion, and decision-making by those responsible for teams, departments and other groups of healthcare staff. Overall the framework guides the decision maker to characterise the degree of risk to staff, articulate feasible options for staff protection in that specific setting and identify the option that ensures any decrease in patient care is proportionate to the increase in staff well-being. It applies specifically to issues of PPE in COVID-19, and also has potential to assist decision makers in other situations involving protection of healthcare staff.
