The nocebo effect is defined as a negative effect of a pharmacological or non-pharmacological medical treatment that is induced by patients' expectations, and that is unrelated to the physiological action of the treatment. The nocebo effect is an important clinical challenge in the current era of biosimilars. Areas covered: This review aims to answer five key questions about the nocebo effect, namely to reveal its definition, pathophysiology, clinical relevance, contributing factors, and management. Expert commentary: The nocebo effect lowers patients' quality of life and negatively affects treatment adherence rates in biosimilar-treated patients. It may negatively impact on the cost-savings of biosimilars. Health-care providers in charge of biosimilar-treated patients need to be aware of the nocebo effect and adopt strategies to minimize it. They have to be well-informed and confident about the existing evidence about biosimilars. A good patient-physician relationship will improve patients' acceptance of biosimilars, and limits the risk of inappropriate negative bias and the nocebo effect.
BackgroundThe aim of the present study was to explore the prospective relationship between anxiety symptoms and coping strategies during late pregnancy and early postpartum.MethodsParticipants completed the Hospital Anxiety Depression-Anxiety subscale and Carver’s Brief COPE at two time points, namely during the last trimester of pregnancy (N = 400) and at two months postpartum (N = 158).ResultsAntenatally, 18.8% of pregnant women presented severe anxiety symptoms while 20.2% of women presented severe anxiety symptoms after birth. Carver's proposed coping styles allowed to significantly distinguish between anxious and non anxious women during these two periods. Anxious women used significantly more inappropriate coping and less adaptive coping responses, such as self-blame and denial of reality, which remained associated with anxiety in the perinatal period. Our results also indicated a decrease in adaptive coping in women without anxiety after birth (e.g. acceptance, positive reframing).ConclusionOur findings confirm that antenatal and postnatal anxiety symptoms occur frequently and that inappropriate and/or non functional coping may account for persisting anxiety after childbirth. Limitations: Data were based on self-reports and participating women were predominantly primiparous. A high drop-out rate at two months postpartum must also be acknowledged.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
