Appropriate enrollment in early-phase clinical trials demands that potential research participants understand and appreciate critical study-related information, because discrepancies in understanding or appreciation can potentially invalidate informed consent to participate in research. Four terms were previously developed to categorize these discrepancies: therapeutic "misconception," "therapeutic misestimation," "therapeutic optimism," and "unrealistic optimism." In this article, we propose a continuous framework of therapeutic misperceptions, rather than discrete categorical concepts. One end of this continuum contains discrepancies in understanding, and at the other end are discrepancies in appreciation. Categorical terminologies represent points along this continuum. Discrepancies in understanding and appreciation each lead to unique ethical concerns and likely require different interventions. This framework highlights the dearth of empirical work on the appreciation end of the continuum, especially related to navigating persistent discrepancies in appreciation. Employing a continuous framework of therapeutic misperceptions supports a nuanced approach to the unique circumstances of each research subject, aiding researchers in supporting truly informed consent.

Importance: Despite guideline recommendations to use low-molecular-weight heparins (LMWHs) or direct oral anticoagulants in the treatment of most patients with acute pulmonary embolism (PE), US-based studies have found increasing use of unfractionated heparin (UFH) in hospitalized patients.

Objective: To identify barriers and facilitators of guideline-concordant anticoagulation in patients hospitalized with acute PE.

Design, Setting, And Participants: This qualitative study conducted semistructured interviews from February 1 to June 3, 2024, that were recorded, transcribed, and analyzed in an iterative process using reflexive thematic analysis.

A mindfulness-based intervention for Substance Use Disorder in a Brazilian vulnerable population: a feasibility mixed method study.

Front Public Health

November 2024

Núcleo de Pesquisa em Saúde e Uso de Substâncias, Departamento de Psicobiologia, Universidade Federal de São Paulo, São Paulo, Brazil.

Introduction: Substance Use Disorder (SUD) is a chronic condition that impacts various facets of an individual's life, and society as a whole. The Mindfulness-Based Relapse Prevention (MBRP) protocol is an innovative intervention that can help to prevent relapse, particularly when used as a post-treatment approach. However, although there is significant evidence of its effectiveness in studies from high-income countries (HICs), there is a dearth of studies examining its feasibility and efficacy in low- and middle-income countries (LMICs).

Reflecting sex, social class and race inequalities in reproduction? Study of the gender representations conveyed by 38 fertility centre websites in 8 European countries.

Reprod Health

INED, Research Unit on Sexual and Reproductive Health and Rights, Campus Condorcet, cours des Humanités-CS 50004, 93322, Aubervilliers, France.

Background: Fertility centre websites are a key sources of information on medically assisted reproduction (MAR) for both infertile people and the general public. As part of a global fertility market, they are also a window to attract potential future patients. They give formal and practical information but in the way the information is displayed, they also convey social representations, and in particular, gender representation in its intersectional dimension.
