RESUMO

BACKGROUND: Systemic symptoms associated with breast implants (SSBI) is a term used to describe a group of patients who attribute a variety of symptoms to their implants. Previous studies have shown symptom improvement after implant removal in these patients irrespective of whether part or all the implant capsule has been removed. OBJECTIVES: The aim of this study was to evaluate implant removal with no capsule removed in symptomatic and control subjects. METHODS: Eligible study subjects were sequentially enrolled at 5 investigator sites. The SSBI Cohort included patients with systemic symptoms they attributed to their implants who requested explantation. The Non-SSBI Cohort included subjects without systemic symptoms attributed to their implants who requested explantation with or without replacement. All subjects agreed to undergo explantation without removal of any capsule. RESULTS: Systemic symptom improvement was noted in SSBI subjects without removal of the implant capsule, comparable to the results of our previously published study. SSBI patients showed a 74% reduction in self-reported symptoms at 6 months with no capsulectomy which was not statistically different from partial or total capsulectomies (P = .23). CONCLUSIONS: Explantation with or without capsulectomy provides symptom improvement in patients with systemic symptoms they associate with their implants.

RESUMO

BACKGROUND: Social learning can be highly adaptive-for example, avoiding a hotplate your friend just burnt themselves on-but it has also been implicated in symptom transmission. Social learning is particularly pertinent given the rapid increase in the use of online mediums for social interaction. Yet, little is known about the social transmission of symptoms online or social chains extending further than a single model-observer interaction. PURPOSE: To explore whether socially induced symptoms could be propagated through a three-generation social transmission chain in an online setting. METHODS: We explored the social transmission of cybersickness following a virtual reality (VR) experience through online webcam interactions. One hundred and seventy-seven adults viewed a VR video in one of four links along a social transmission chain, after: viewing an actor model cybersickness to the VR video (First-Generation); viewing the First-Generation participant undergo VR (Second-Generation); viewing the Second-Generation participant undergo VR (Third-Generation); or naïve (Control). RESULTS: Cybersickness was strongest in First-Generation participants, indicating social transmission from the model. This was mediated by expectancy and anxiety. Whether or not subsequent generations experienced cybersickness depended on what the observed participant verbally reported, which is consistent with social transmission. CONCLUSIONS: Results demonstrate that symptoms can be readily transmitted online, and that expectancy and anxiety are involved. Although it is inconclusive as to whether symptoms can propagate along a social transmission chain, there is some evidence of protection from symptoms when a model who does not report any symptoms is observed. As such, this research highlights the role of social transmission in the modulation of symptoms through virtual mediums.


Social learning is a ubiquitous cognitive process whereby our own behaviors and experiences are influenced by observing others. Occasionally, this can involve the observation of an individual experiencing negative outcomes (e.g., pain or symptoms) following exposure to a treatment or intervention (e.g., consumption of medicine). Previous research has found that individuals may experience an increase in symptoms due to this social learning, even when their treatment has no active components. While research has primarily explored situations in which there is one model and one observer, it was of interest as to whether these socially induced symptoms can be transmitted beyond the first observer. Moreover, with social interaction through online mediums such as social media and video conferencing becoming more common, it was also of interest as to whether these symptoms can be transmitted online. The present findings highlight the significant role of social learning in symptom transmission, even when interactions occur online. With expectancy and anxiety being key features of this social transmission, this study highlights important implications for understanding how individuals can learn about their own future experiences through the observation of others.

RESUMO

Medication side effect information can create negative patient expectations of side effects, but such information is considered crucial to informed consent. The current study investigated the effect of informing participants of different numbers of medication side effects. Willingness to take the medication was highest for those informed of one or four compared with none or 26 side effects, and memory of side effects was also more accurate. Findings suggest that informing patients of some, but not several, side effects may optimise both medication adherence and accuracy of informed consent.

RESUMO

BACKGROUND: Breast Implant Illness (BII) describes a variety of symptoms reported by patients with breast implants. Biospecimens data revealed minimal statistical differences between BII and non-BII cohorts. Baseline analysis of PROMIS data demonstrated significant differences between the BII cohort and the 2 control cohorts. OBJECTIVES: This study was designed to determine if patients in the BII cohort obtained any symptom improvement after explantation, whether symptom improvement was related to the type of capsulectomy, and which symptoms improved. METHODS: A prospective blinded study enrolled 150 consecutive patients divided equally into 3 cohorts. Baseline demographic data and a systemic symptoms survey, including PROMIS validated questionnaires, were obtained at baseline, 3 to 6 weeks, 6 months, and 1 year. RESULTS: A total of 150 patients were enrolled between 2019 and 2021. Follow-up at 1 year included 94% of the BII cohort and 77% of non-BII and mastopexy cohorts. At 1 year, 88% of patients showed at least partial symptom improvement, with a reduction of 2 to 20 symptoms. The PROMIS score in the BII cohort decreased at 1 year for anxiety, sleep disturbances, and fatigue. Systemic symptom improvement was noted out to 1 year in the BII cohort regardless of the type of capsulectomy performed. CONCLUSIONS: Parts 1-3 in this series concluded that there were no consistent differences in biospecimen results between the cohorts. Unlike the data observed in the biospecimen analysis, BII patients had heightened symptoms and poorer PROMIS scores at baseline compared to the control cohorts. The reduction of negative expectations and a potential nocebo effect could contribute to this improvement.

RESUMO

BACKGROUND: Vaccines are being administered worldwide to combat the COVID-19 pandemic. Vaccine boosters are essential for maintaining immunity and protecting against virus variants. The side effects of the primary COVID-19 vaccine (e.g., headache, nausea), however, could reduce intentions to repeat the vaccination experience, thereby hindering global inoculation efforts. PURPOSE: The aim of this research was to test whether side effects of a primary COVID-19 vaccine relate to reduced intentions to receive a COVID-19 booster. The secondary aim was to test whether psychological and demographic factors predict booster intentions. METHODS: Secondary data analyses were conducted on a U.S. national sample of 551 individuals recruited through the online platform Prolific. Key measures in the dataset were side effects reported from a primary COVID-19 vaccination and subsequent intentions to receive a booster vaccine. Psychological and demographic variables that predicted primary vaccination intentions in prior studies were also measured. RESULTS: Booster intentions were high. COVID-19 booster vaccine intentions were uncorrelated with the number of side effects, intensity of side effects, or occurrence of an intense side effect from the primary COVID-19 vaccine. Correlational and regression analyses indicated intentions for a booster vaccination increased with positive vaccination attitudes, trust in vaccine development, worry about the COVID-19 pandemic, low concern over vaccine side effects, and democratic political party affiliation. CONCLUSIONS: Side effects of a primary COVID-19 vaccine were not directly associated with lower intentions to receive a booster of the COVID-19 vaccine early in the pandemic. However, many variables that predict primary vaccination intentions also predict booster intentions.

RESUMO

Attribute framing presents an ethically sound approach for reducing adverse nocebo effects. In past studies, however, attribute framing has not always decreased nocebo effects. The present study used a sham tDCS procedure to induce nocebo headaches to explore factors that may contribute to the efficacy of attribute framing. Participants (N = 174) were randomized to one of three between-subject conditions: a no-headache instruction (control) condition and two conditions in which headaches were described as either 70% likely (negative framing) to occur or 30% unlikely (positive framing) to occur. Results revealed nocebo headaches in both framing conditions, as compared to the control condition. Attribute framing did not influence headache measures recorded during the sham tDCS task, but framing did have a modest influence on one of two headache items completed after the task. Results suggest that attribute framing could have a stronger influence on delayed nocebo effect measures or retrospective symptom reports; a finding that may explain inconsistencies in the existing framing-nocebo effect literature. Exploratory analyses also revealed that low negative affect was associated with stronger nocebo and attribute framing effects, although these effects were found on only a few headache measures. It is concluded that researchers should further investigate the influence of attribute framing on nocebo headaches as a function of both timing and emotional factors.

RESUMO

The social facilitation of eating refers to people's tendency to eat more food when dining with others than when dining alone. Recent research suggests that social facilitation may be driven by people's tendency to make more food available even before social meals begin, a phenomenon referred to as social "precilitation." In order to uncover the mechanisms underlying social precilitation, it is helpful to first understand whether people consciously and deliberately make more food available for social meals. Three studies (total N = 792) used an online serving paradigm to investigate this question. Participants were asked to imagine dining alone and dining socially, and indicated how much food they would serve themselves in each scenario. Unexpectedly, participants consistently reported intending to serve themselves smaller portions for social meals than for non-social meals (Study 1). This effect emerged even when they were asked about how someone else would behave (Study 2), and when they were informed that there was plenty of food available at the social meal (Study 3). This research highlights a disconnect between people's intended serving behaviour and the actual serving behaviour observed in laboratory studies, and suggests that people may not be aware of how their behaviour is influenced by the social context. Future research should examine why the disconnect between people's intended and actual serving behaviour occurs, whether it is related to the amount of food provided for social meals, and what implications the disconnect has for people's ability to manage their food intake.

RESUMO

BACKGROUND: Breast implant illness (BII) is a term used to describe physical and psychological symptoms experienced by some women following breast implant surgery. Few studies have examined the experiences of women with BII-a poorly understood condition with no clear cause or treatment. OBJECTIVES: The aim of this study was to explore women's experiences of BII, including symptoms, healthcare encounters, social media, and explant surgery. METHODS: Employing an exploratory qualitative methodology, researchers undertook semistructured interviews with 29 women who self-identified as having BII. Interviews were audio-recorded and transcribed verbatim. Data were analyzed by inductive thematic analysis. RESULTS: Thematic analysis of the interviews identified 6 themes: (1) symptoms without explanation; (2) invalidation and invisibility; (3) making the BII connection; (4) implant toxicity; (5) explant surgery: solution to suffering?; and (6) concealed information. BII was described as distressing and debilitating across multiple domains including relationships, work, identity, and physical and mental health, and symptoms were attributed to implant toxicity and immune system rejection of foreign objects. When their experience was not validated by healthcare professionals, many looked to social media for information, support, and understanding, and saw explant as their only chance of recovery. CONCLUSIONS: BII is disabling mentally and physically. Women with BII require support, understanding, and validation, and proactive treatment to prevent disability. With unclear pathophysiology, future research should examine how biopsychosocial approaches can be used to guide treatment, and how to best support women with BII, focusing on early detection and evidence-based education and intervention.

RESUMO

BACKGROUND: Side effect warnings can contribute directly to their occurrence via the nocebo effect. This creates a challenge for clinicians and researchers, because warnings are necessary for informed consent, but can cause harm. Positive framing has been proposed as a method for reducing nocebo side effects whilst maintaining the principles of informed consent, but the limited available empirical data are mixed. PURPOSE: To test whether positive attribute framing reduces nocebo side effects relative to negative framing, general warning, and no warning. METHODS: Ninety-nine healthy volunteers were recruited under the guise of a study on virtual reality (VR) and spatial awareness. Participants were randomized to receive positively framed ("7 out of 10 people will not experience nausea"), negatively framed ("3 out of 10 people will experience nausea"), general ("a proportion of people will experience nausea"), or no side effect warnings prior to VR exposure. RESULTS: Receiving a side effect warning increased VR cybersickness relative to no warning overall, confirming that warnings can induce nocebo side effects. Importantly, however, positive framing reduced cybersickness relative to both negative framing and the general warning, with no difference between the latter two. Further, there was no difference in side effects between positive framing and no warning. CONCLUSIONS: These findings suggest that positive framing not only reduces nocebo side effects relative to negative framing and general warnings, but actually prevents nocebo side effects from occurring at all. As such, positive attribute framing may be a cheap and ethical way to reduce nocebo side effects.

RESUMO

BACKGROUND: Breast implant surgery is the most common plastic surgery procedure performed globally. A subset of women with breast implants report experiencing a myriad of disabling and distressing physical and psychological symptoms attributed to their implants. Social media groups have coined the condition "breast implant illness" (BII). Little to no scientific research currently exists for BII. OBJECTIVES: The aim of this study was to investigate the experiences of women with BII (both those with implants still in place and those who have explanted) and compare them with those of a control group of women with implants who do not report BII. METHODS: Women with self-reported BII and implants still in place (n = 51), self-reported BII who had explanted (n = 60), and women with implants in place without BII (n = 58) completed online self-report questionnaires about their symptoms, physical and mental health, health service use patterns, and lifestyle factors (eg, exercise, smoking, alcohol consumption). RESULTS: Women with BII, regardless of whether they had undergone explant surgery, reported experiencing more severe somatic symptoms, higher depression, anxiety and health anxiety, and poorer physical health than women without BII. CONCLUSIONS: These findings highlight the need for further investigation into the causes, risk factors, long-term effects, and potential interventions for women who experience BII.

RESUMO

INTRODUCTION AND HYPOTHESIS: Evidence regarding how women feel about episiotomies is not recorded in the literature. As the most common surgical procedure, there is a need to understand how women feel about episiotomy. METHODS: The primary outcome was to identify the percentage of women who would accept an episiotomy if required. A literature review was compiled to provide nulliparous women in their third trimester with evidence-based information about episiotomies and perineal tears. Questions eliciting demographics, pre-information level of anxiety and acceptance of episiotomy were asked. After reading the information sheets, anxiety and knowledge were assessed again. Changes in anxiety levels from pre- to post-information were investigated using paired samples t tests. Because anxiety was measured on a scale, we assessed potential departures from normality by using the Wilcoxon signed-rank test. Questions also assessed the value women placed on this form of education. RESULTS: There were 105 responses, with 88% accepting episiotomy, 2% declining and 10% seeking more information to decide. Eighty-one percent of women agreed that the information provided helped them to understand more about childbirth and 62% agreed that they felt more comfortable with the birthing process after reading the material. There was a reduction in anxiety levels regarding episiotomies after reading information (p = 0.002) and perineal tears (p = 0.02). CONCLUSIONS: Most women will accept an episiotomy if required. Antenatal education about episiotomies is important to women and helps them feel more comfortable with the birthing process. Written information increases acceptance and reduces anxiety levels regarding episiotomies.

RESUMO

Background: Recent evidence indicates that placebo effects can occur even when patients know that they are taking a placebo, termed the open-label placebo effect. Aim: To assess whether placebo dose (one pill per day vs. four pills per day), treatment expectancies, and adherence contribute to open-label placebo effects. Method: Healthy undergraduate participants were randomly assigned to take one or four open-label placebo pills per day or to a no-treatment control group. Placebo-treated participants took a 5-day course of an open-label placebo described as enhancing physical (symptoms and sleep) and psychological (positive and negative emotional experience) well-being. Expectancies about placebo effectiveness and well-being were assessed at baseline, and well-being and adherence were assessed after the 5-day course of treatment. Results: Medium-to-large open-label placebo effects were evidenced in all well-being outcomes including sleep quality. Dose did not influence these effects. Both treatment expectancies and adherence were significant independent predictors of enhanced well-being in the two psychological well-being outcomes and the experience of physical symptoms, but sleep quality improved independently. Conclusions: This is the first study to demonstrate the effect of open-label placebos in improving well-being and sleep quality and to show that open-label placebo reposes do not appear to be dose-dependent, but for most well-being outcomes are independently predicted by both positive expectancies and treatment adherence.

RESUMO

BACKGROUND: One contributing factor to the development of nocebo effects is information provided about possible side effects. However, nondisclosure of information can be problematic. PURPOSE: We assessed whether positively framed side effect information (highlighting likelihood of not experiencing side effects) can reduce nocebo effects compared to negatively framed information (highlighting likelihood of experiencing side effects). METHODS: One hundred twelve participants took part in research ostensibly assessing the influence of benzodiazepines (actually sham capsules) on anxiety. Participants were randomized to receive a sham capsule with positively or negatively framed information about four side effects, or a no-treatment control condition. Side effect expectations were assessed after information provision. Framed side effects and other unmentioned symptoms were assessed during the session and 24-hr follow-up. RESULTS: Nocebo effects occurred in symptoms presented as side effects (regardless of framing) during the study session and follow-up (ps < .003). At follow-up, there was also a nocebo effect in other unmentioned symptoms (p = .018). Positive framing reduced side effect symptoms compared with negative framing during the study session (p = .037), but this effect was no longer present at follow-up (p = .53). Side effect expectations did not differ between the framing conditions (p = .14). CONCLUSIONS: Positive framing reduced side effects short-term, but not at follow-up. Expectations did not differ between negative and positive framing. Nocebo effects appeared to generalize to other unmentioned symptoms over a 24-hr period. Further research is needed to determine whether the initial impact of positive framing can be maintained over time.

RESUMO

Background: Social modeling has the capacity to shape treatment outcomes, including side effects. Purpose: This study investigated the influence of social modeling of treatment side effects, gender, and participant empathy, on side effects of a placebo treatment. Methods: Ninety-six participants (48 females) completed a study purportedly investigating the influence of modafinil (actually placebo) on alertness and fatigue. The participants were randomly seated with a male or female confederate and saw this confederate report experiencing side effects or no side effects. Participant empathy was assessed at baseline. Changes in modeled and general symptoms, and misattribution of symptoms, were assessed during the session and at 24-hr follow-up. Results: During the experimental session, seeing side effect modeling significantly increased modeled symptoms (p = .023, d = 0.56) but not general or misattributed symptoms. Regardless of modeling condition, female participants seated with a female model reported significantly more general symptoms during the session. However, response to social modeling did not differ significantly by model or participant gender. At follow-up, the effect of social modeling of side effects had generalized to other symptoms, resulting in significantly higher rates of modeled symptoms (p = .023, d = 0.48), general symptoms (p = .013, d = 0.49), and misattributed symptoms (p = .022, d = 0.50). The experience of modeled symptoms in response to social modeling was predicted by participants' levels of baseline empathy. Conclusions: Social modeling of symptoms can increase the side effects following treatment, and this effect appears to generalize to a broader range of symptoms and symptom misattribution over time. Higher baseline empathy seems to increase response to social modeling.

RESUMO

OBJECTIVE: Choice may be an important influence on the effectiveness and side effects of medical treatments. PURPOSE: We investigated the impact of having a choice of medication compared to no choice on both nocebo and placebo responding. METHODS: Sixty-one participants were randomly assigned to either choose between or be assigned to one of the two equivalent beta-blocker medications (actually placebos) for pre-examination anxiety. RESULTS: There was a greater nocebo response in the no choice group and an increased placebo response in the choice group. Participants in the no choice group attributed significantly more side effects to the tablet than the choice group (p = 0.045), particularly at the 24-h follow-up (p = 0.002). The choice group showed a stronger placebo response in heart rate than the non-choice group. CONCLUSION: Not being given a choice of medication increased the nocebo effect and reduced the placebo response to the treatment.

RESUMO

PURPOSE: The belief that one is especially sensitive to the actions and side effects of medicines can influence treatment adherence and side-effect reporting. In this study, we investigated the prevalence of perceived medication sensitivity in the general population and its relationship to symptom complaints, information seeking about medications, use of medical care and demographic factors. METHODS: A nationally representative sample of 1000 New Zealand residents completed the Perceived Sensitivity to Medicines scale and symptoms experienced during the previous 7 days. Demographic data and medical visits, medication use and information seeking about medicines were also collected. RESULTS: Over 20% of the general population reported being very sensitive to the effects of medication (20.2%) and that small amounts of medicines can upset their body (25.3%). Participants who reported high levels of perceived sensitivity to medicines reported significantly more symptoms (M = 9.54, SE = 0.47) than people with low (M = 5.04, SE = 0.49) or moderate (M = 5.91, SE = 0.24) levels, ps < .001. This relationship was strongest in participants who were currently taking prescription medication. Those with high perceived sensitivity also reported being more likely to seek information about medicines, and had significantly more general practitioner visits. CONCLUSIONS: Perceived sensitivity to medicines is common in the population and associated with important clinical variables including information seeking, GP visits and symptom reporting. Identifying patients with higher perceived sensitivity to medicines may improve patient care by providing the basis for targeted and personalised interventions to reduce side effects and improve adherence to medications.

RESUMO

OBJECTIVE: Side effect information is routinely communicated online. However, limited experimental evidence exists regarding the role of this information in generating maladaptive health outcomes (i.e., the nocebo effect). A novel paradigm was developed to remotely induce the nocebo effect via provision of online side effect information. METHOD: Participants were given information regarding the positive effects of low frequency noise (LFN). A proportion were additionally warned of LFN-induced side effects. Study 1 (N = 423) investigated the source of information (listed vs. socially communicated side effects), while Study 2 (N = 560) investigated the role of positive and negative affects on attenuating and exacerbating the nocebo effect. Pooled analysis (N = 983) explored the effect of negative and positive expectations on both the nocebo effect and positive outcomes. RESULTS: Across studies, a significant nocebo effect in the warned side effects occurred after LFN exposure. This did not vary by source of information (Study 1) nor was it attenuated via the induction of positive affect (Study 2). Both studies demonstrated a reduction in positive outcomes among those receiving side effect information. Pooled analysis revealed that negative, but not positive, expectations mediated the nocebo effect. Positive and negative expectations interacted to predict positive outcomes. Holding negative expectations appeared to block positive health outcomes. Specifically, when negative expectations were above average, there was no effect of positive expectations on positive outcomes. CONCLUSIONS: Nocebo effects were remotely generated via minimal provision of side effect information. Pooled analysis revealed that future interventions should target positive and negative expectations to reduce side effects. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

The perception of taking a generic, relative to brand, medication has been demonstrated to exacerbate the nocebo effect. Conversely, positive attribute framing has been shown to attenuate the nocebo effect. However, little is known about the longevity of positive attribute framing nor how it interacts with generic versus brand treatment cues. Healthy participants (N = 205) were randomised to receive either sham-modafinil capsules with a brand or generic appearance, in conjunction with standard negative side effect framing (brand-negative: N = 42; generic-negative: N = 41) or positive side effect framing (brand-positive: N = 40; generic-positive: N = 40). The remainder were randomised to a no-treatment control (N = 42). Participants were informed that modafinil could enhance alertness and cognitive performance and reduce fatigue. Critically, modafinil was described as having several potential side effects. Treatment-related side effects, alertness, fatigue and cognitive performance were measured at baseline, 30-min post-treatment and 24 h later. Nocebo and placebo effects were observed across modafinil-treated participants relative to control. Positive framing significantly reduced warned side effects for 24 h. Perceived side effect likelihood, severity, and worry mediated the nocebo, but not framing, effect.

RESUMO

OBJECTIVE: People with autoimmune and inflammatory rheumatic disease (AIIRD) are at an increased risk of morbidity from COVID-19. While COVID-19 vaccination is effective at reducing disease complications, there have been significant levels of vaccine hesitancy in people with AIIRD. We aimed to understand vaccine hesitancy and promote shared decision-making by describing the experiences and perspectives of people with AIIRD who had concerns with COVID-19 vaccinations. METHODS: Adults with AIIRD on immunosuppressive medications who expressed concerns regarding the COVID-19 vaccination were purposively sampled until thematic saturation. Individual semi-structured interviews were conducted and analysed using reflexive thematic analysis. RESULTS: Sixteen adults with an AIIRD were interviewed. Thematic analysis yielded four themes: heightened sense of vulnerability; determining individual suitability; desperate for freedom and relief; deterred by scepticism. CONCLUSIONS: The perspectives of people with AIIRD towards the COVID-19 vaccination were shaped by a sense of vulnerability. The decision-making experience was challenging, resulting from struggles with handling information, dealing with external pressures, and facing negativity. PRACTICE IMPLICATIONS: A collaborative approach, involving close family and friends and avoiding negativity and pressure can improve engagement and support decision-making around COVID-19 vaccination. Clearly addressing potential risks of vaccination may prevent subsequent regret and hesitancy if they arise.
