Biomechanical response of ultrathin slices of hypertrophic cardiomyopathy tissue to myosin modulator mavacamten

Hypertrophic cardiomyopathy (HCM) is the most common inherited myocardial disorder of the heart, but effective treatment options remain limited. Mavacamten, a direct myosin modulator, has been presented as novel pharmacological therapy for HCM. The aim of this study was to analyze the biomechanical response of HCM tissue to Mavacamten using living myocardial slices (LMS). LMS (n = 58) from patients with HCM (n = 10) were cultured under electromechanical stimulation, and Verapamil and Mavacamten were administered on consecutive days to evaluate their effects on cardiac biomechanics. Mavacamten and Verapamil reduced contractile force and dF/dt and increased time-to-relaxation in a similar manner. Yet, the time-to-peak of the cardiac contraction was prolonged after administration of Mavacamten (221.0 ms (208.8 – 236.3) vs. 237.7 (221.0 – 254.7), p = 0.004). In addition, Mavacamten prolonged the functional refractory period (FRP) (330 ms (304 − 351) vs. 355 ms (313 − 370), p = 0.023) and better preserved twitch force with increasing stimulation frequencies, compared to Verapamil. As such, Mavacamten reduced (hyper-)contractility and prolonged contraction duration of HCM LMS, suggesting a reduction in cardiac wall stress. Also, Mavacamten might protect against the development of ventricular tachyarrhythmias due to prolongation of the FRP, and improve toleration of tachycardia due to better preservation of twitch force at tachycardiac stimulation frequencies.</p

Information and participation preferences and needs of non-Western ethnic minority cancer patients and survivors: A systematic review of the literature

Objective: To provide an overview of information and participation preferences and needs of non-Western ethnic minority cancer patients living in Western countries. Methods: A systematic literature review was conducted using the databases PsycINFO, PubMed, CINAHL, and EMBASE. Thematic analysis was carried out to synthesize data, allowing for identification of important themes and synthesis of both qualitative and quantitative studies. Results: Forty-four papers were included. Non- Western ethnic minority cancer patients/survivors have high information preferences and needs regarding topics ranging from diagnosis to treatment and from prevention to the healthcare system. Younger, female, and unmarried patients/survivors, and patients with better language proficiency reported higher information preferences. Latin-American and African-American patients/survivors primarily prefer shared or active participation. Asian and Middle-Eastern patients/survivors prefer primarily passive participation. Younger patients, and those with a higher level of education and acculturation were more likely to prefer active or shared participation. Conclusion: Further (quantitative) research on factors associated with patients’ preferences is needed in order to better understand the underlying reasons of information and participation preferences and needs of diverse non-Western ethnic minority cancer patients. Practice implications: To better fulfil ethnic minority patients’/survivors’ preferences and needs healthcare providers should elaborate upon these and tailor their information- provision accordingly

Mitigating language and cultural barriers in healthcare communication: Toward a holistic approach

Due to ongoing globalization and migration waves, healthcare providers are increasingly caring for patients from diverse cultural and/or ethnic minority backgrounds. Adequate health communication with migrants and ethnic minorities is often more difficult to establish compared to people belonging to the majority groups of a given society, because of a combination of language and cultural barriers. To address this topic, in December 2018 a symposium was organized-under the auspices of the Amsterdam Center for Health Communication-during which speakers from both academia and professional practice discussed the current state-of-the-art and brought forward innovative solutions to improve intercultural communication in healthcare. Main questions that were discussed during this symposium included: "How can language barriers in intercultural health communication be mitigated?" and "Which innovations can contribute to improving intercultural health communication?" In this paper, we discuss some answers to these questions and propose that in order to enhance intercultural communication and healthcare for migrant and ethnic minority patients, a more holistic approach to studying when, how, and for what purposes (a combination of) communication strategies should be utilized in mitigating both language and cultural barriers to decrease health disparities and improve health care for migrant and ethnic minority patients.status: accepte

Does Media Use Result in More Active Communicators? Differences Between Native Dutch and Turkish-Dutch Patients in Information-Seeking Behavior and Participation During Consultations With General Practitioners

This study investigates differences between native Dutch and Turkish-Dutch patients with respect to media usage before and patient participation during medical consultations with general practitioners. In addition, the authors assessed the relation between patient participation and communication outcomes. The patients were recruited in the waiting rooms of general practitioners, and 191 patients (117 native Dutch, 74 Turkish-Dutch) completed pre- and postconsultation questionnaires. Of this sample, 120 patients (62.8%; 82 native Dutch, 38 Turkish-Dutch) agreed to have their consultations recorded to measure patient participation. Compared with Turkish-Dutch patients of similar educational levels, results showed that native Dutch patients used different media to search for information, participated to a greater extent during their consultations and were more responsive to their general practitioner. With respect to the Turkish-Dutch patients, media usage was related to increased patient participation, which was correlated with having fewer unfulfilled information needs; however, these relations were not found in the native Dutch patient sample. In conclusion, interventions that enhance participation among ethnic minority patients will better fulfill informational needs when such interventions stimulate information-seeking behavior in that group before a medical consultation
