RESUMO

Our well-being can improve when people heed evidence rather than simply follow familiar or charismatic advisors who neglect evidence. We developed the Reasoning through Evidence versus Advice (EvA) scale to measure individual differences in reasoning through evidence like science and statistics versus following advisors such as politicians and celebrities. No existing scales directly measure these tendencies; moreover, it was theoretically unknown whether they reflect a single dimension (from evidence- to advice-based) or distinct tendencies to value or distrust each. Our scale validation process included qualitative interviews and four studies that involved 1583 respondents (753 college graduates, 830 non-college graduates) in which we conducted exploratory and confirmatory factor analyses and tests of convergent validity, discriminant validity, and measurement invariance by gender and education. This process yielded a 16-item EvA scale with four dimensions: Pro-evidence, Anti-evidence, Pro-advice, and Anti-advice. In assessing criterion validity, these tendencies identified individual differences in important, real-world attitudes and behaviors, including susceptibility to health misinformation, adherence to CDC guidelines on social distancing, confidence in the COVID vaccine, science curiosity, and religiosity. The EvA scale extends our understanding of individual differences in reasoning tendencies that shape critical attitudes, decisions, and behaviors and can help promote informed decisions.

RESUMO

PURPOSE OF REVIEW: A recent increase in legislation in the United States prohibiting gender-affirming care (GAC) for transgender youth follows a wave of its politicization despite support from all pertinent mainstream medical associations. This review describes the standards of GAC for transgender youth, the origins of legislation prohibiting this care, a review of current legislation in the United States and a discussion on the impact on patients, providers, and the medical field. RECENT FINDINGS: A critical evaluation of historical parallels and current organizations supporting this legislation reveals it stems not from concerns within the medical field but from political and religious interests. This intrusion sets a dangerous precedent, undermining evidence-based medicine, providers' ability to practice according to standards of care, and patients' and guardians' autonomy and medical decision-making. This wave of antitrans rhetoric and legislation has resulted in threats to health providers and hospitals, 'moral distress" in providers, and migration of providers and patients from hostile states. SUMMARY: Similar to antiabortion legislation, these legislative efforts will likely result in negative health outcomes and worsening disparities. The medical community must confront these forces directly through an understanding of the political and structural forces at play and adopting strategies to leverage collective power.

RESUMO

The evidence-based treatment (EBT) movement has primarily focused on core intervention content or treatment fidelity and has largely ignored practitioner skills to manage interpersonal process issues that emerge during treatment, especially with difficult-to-treat adolescents (delinquent, substance-using, medical non-adherence) and those of color. A chief complaint of "real world" practitioners about manualized treatments is the lack of correspondence between following a manual and managing microsocial interpersonal processes (e.g. negative affect) that arise in treating "real world clients." Although family-based EBTs share core similarities (e.g. focus on family interactions, emphasis on practitioner engagement, family involvement), most of these treatments do not have an evidence base regarding common implementation and treatment process problems that practitioners experience in delivering particular models, especially in mid-treatment when demands on families to change their behavior is greatest in treatment - a lack that characterizes the field as a whole. Failure to effectively address common interpersonal processes with difficult-to-treat families likely undermines treatment fidelity and sustained use of EBTs, treatment outcome, and contributes to treatment dropout and treatment nonadherence. Recent advancements in wearables, sensing technologies, multivariate time-series analyses, and machine learning allow scientists to make significant advancements in the study of psychotherapy processes by looking "under the skin" of the provider-client interpersonal interactions that define therapeutic alliance, empathy, and empathic accuracy, along with the predictive validity of these therapy processes (therapeutic alliance, therapist empathy) to treatment outcome. Moreover, assessment of these processes can be extended to develop procedures for training providers to manage difficult interpersonal processes while maintaining a physiological profile that is consistent with astute skills in psychotherapeutic processes. This paper argues for opening the "black box" of therapy to advance the science of evidence-based psychotherapy by examining the clinical interior of evidence-based treatments to develop the next generation of audit- and feedback- (i.e., systemic review of professional performance) supervision systems.

RESUMO

Chater & Loewenstein argue for a shift in focus from individual- to structural-level approaches to societal ills. This is valid and important but overlooks the barriers inherent in the current US partisan context. Psychology can be applied to help people of mixed allyship join together, to effectively and quickly force institutions and corporations to accept structural change.

RESUMO

Background: Methods that aim to accurately measure and predict breast development can be utilized in gender-affirming treatment planning, patient education, and research. Objectives: The authors sought to evaluate whether three-dimensional (3D) stereophotogrammetry accurately measures transfeminine breast volume changes on a masculine frame when simulating anticipated changes in soft tissue after gender-affirming surgical therapy. Then, we describe the innovative application of this imaging modality in a transgender patient to illustrate the potential role of 3D imaging in gender-affirming surgical care. Methods: A 3D VECTRA scanner (Canfield, Fairfield, NJ) was used to measure anthropometric breast measurements. Postoperative changes in breast volume were simulated on a cardiopulmonary resuscitation mannequin using 450 cc MENTOR breast implants (Mentor Worldwide LLC, Irvine, CA). To demonstrate the ability of the VECTRA to accurately simulate transfeminizing augmentation in practice, we describe its use in a 30-year-old transgender female with a 2-year history of gender-affirming hormone therapy, presenting for gender-affirming surgical care. Results: In the mannequin, mean breast volumes were 382 cc on the right (range 375-388 cc), and 360 cc on the left (range 351-366 cc). The average calculated difference in volume between the 2 sides was 22 cc (range 17-31 cc). There were no instances where the left side was calculated to be larger than the right or where the calculated size was smaller than the actual implant size. Conclusions: The VECTRA 3D camera is a reliable and reproducible tool for preoperative assessment, surgical planning, and simulating breast volume changes after gender-affirming surgery.

RESUMO

Introduction: Why do people help strangers? Prior research suggests that empathy motivates bystanders to respond to victims in distress. However, this work has revealed relatively little about the role of the motor system in human altruism, even though altruism is thought to have originated as an active, physical response to close others in immediate need. We therefore investigated whether a motor preparatory response contributes to costly helping. Methods: To accomplish this objective, we contrasted three charity conditions that were more versus less likely to elicit an active motor response, based on the Altruistic Response Model. These conditions described charities that (1) aided neonates versus adults, (2) aided victims requiring immediate versus preparatory support, and (3) provided heroic versus nurturant aid. We hypothesized that observing neonates in immediate need would elicit stronger brain activation in motor-preparatory regions. Results: Consistent with an evolutionary, caregiving-based theory of altruism, participants donated the most to charities that provided neonates with immediate, nurturant aid. Critically, this three-way donation interaction was associated with increased BOLD signal and gray matter volume in motor-preparatory regions, which we identified in an independent motor retrieval task. Discussion: These findings advance the field of altruism by shifting the spotlight from passive emotional states toward action processes that evolved to protect the most vulnerable members of our group.

RESUMO

Introduction: People exhibit a strong attachment to possessions, observed in behavioral economics through loss aversion using new items in the Endowment or IKEA effects and in clinical psychology through pathological trouble discarding domestic items in Hoarding Disorder. These fields rarely intersect, but both document a reticence to relinquish a possessed item, even at a cost, which is associated with feelings of loss but can include enhanced positive states as well. Methods: To demonstrate the shared properties of these loss-related ownership effects, we developed the Pretzel Decorating Task (PDT), which concurrently measures overvaluation of one's own over others' items and feelings of loss associated with losing a possession, alongside enhanced positive appraisals of one's items and an effort to save them. The PDT was piloted with 31 participants who decorated pretzels and responded to their own or others' items during functional neuroimaging (fMRI). Participants observed one item per trial (self or other) and could work to save it (high or low probability loss) before learning the fate of the item (trashed or saved). Finally, participants rated items and completed hoarding tendency scales. Results: The hypotheses were supported, as even non-clinical participants overvalued, viewed as nicer, feared losing, and worked harder to save their items over others'-a response that correlated with hoarding tendencies and motor-motivational brain activation. Our region of interest in the nucleus accumbens (NAcc) was engaged when viewing one's own items to the extent that people worked harder to save them and was more active when their items were saved when they felt emotionally attached to possessions in real life. When their items were trashed, NAcc activity negatively correlated with trouble discarding and emotional attachments to possessions. Right anterior insula was more active when working to save one's own over others' items. Extensive motor-motivational areas were engaged when working to save one's own over others' items, including cerebellum, primary motor and somatosensory regions, and retrosplenial/parahippocampal regions-even after controlling for tapping. Discussion: Our attachments to items are emotional, continuous across typical and pathological populations, and drive us to save possessions that we value.

RESUMO

OBJECTIVE: To develop an imaging modality for the postoperative phalloplasty urethra. Despite high urologic complication rates after masculinizing genital surgery, existing methods for postsurgical evaluation after phalloplasty have drawbacks. Fluoroscopic studies like the retrograde urethrogram have limitations like user-dependence and need for meticulous positioning but also are inadequate for the evaluation of the anatomically complex postphalloplasty urethra. We developed a novel protocol utilizing CT urethrography with 3D reconstruction using cinematic rendering (3DUG) for neo-urethral imaging. MATERIALS AND METHODS: Patients who underwent 3DUG after either phalloplasty, metoidioplasty, or prior to revision surgery were included. Low-dose imaging protocols were used to avoid any increases in radiation exposure. The first iteration of our protocol utilized retrograde contrast administration via the penile urethra, whereas the second iteration of our protocol utilized an antegrade technique with contrast instillation via the suprapubic catheter and a voiding scan. Imaging was initially obtained according to symptoms and then per protocol at 3 weeks after urethral lengthening. RESULTS: Twenty-six patients were included in the series. Among postoperative phalloplasty patients imaged for symptoms, contrast extravasation/fistula was identified in 5 (63%), vaginal remnant in 3 (38%), and stricture in 2 (25%) compared to 5 (45%), 1 (9%), and zero respectively for patients imaged routinely. When intervention was required, operative findings correlated to anatomy on imaging. CONCLUSION: We present a new protocol for the use of 3D CT urethrography with cinematic rendering for neo-urethral reconstruction. This technique has the potential to improve surgical planning and surveillance of urologic complications in postphalloplasty patients.

RESUMO

The average American believes in climate change, worries about it, and supports related policy, but there are still considerable differences-across individuals and with political ideology-that limit the ability to foster change. Researchers and practitioners often increase concern and action for others through feelings of empathy, which also increases pro-environmentalism. However, some people appear less emotionally impacted by environmental destruction-particularly more ideologically conservative and less pro-environmental individuals. To determine why some people appear to be impassive to environmental destruction, we conducted 3 online studies to measure beliefs and emotional processes in political liberals versus conservatives. Across 3 studies, we replicated the link between impassivity and conservatism, and found that more impassive people acknowledge our negative impact on the environment but are less concerned about it and more confident in an eventual solution. Impassivity, however, is not specific to the environment. People who are more impassive about the environment also respond less emotionally to positive and negative images that are unrelated to the environment, including human suffering and hedonic reward. They also report reduced trait empathy, perspective taking, and daily emotional expression and experience. Impassivity is not linked to differences in trait personal distress, anxiety, psychopathy (apart from low empathy), or trouble appreciating consequences. Impassivity is not associated with deficits in processing others' facial emotion during early perceptual decoding but is associated with the later suppression of emotion. Everyone will not respond to emotional appeals to help a distressed environment. Other strategies are recommended to reach a broad audience.

RESUMO

Due to growing social acceptance, there has been an increasing number of gender-affirmation surgeries performed in North America. Most research in this patient population focuses on surgical outcomes and advancing techniques. However, little work has been done to study functional outcomes. To better evaluate urinary dysfunction in the postphalloplasty trans men patient population, our group developed a novel patient-reported outcome instrument - the postphalloplasty urinary function test (PP UFT) and protocol to measure postvoid urethral volume (PVUR), and we present our preliminary results. We conducted a cross-sectional pilot study in a cohort of 15 adult trans men who had undergone phalloplasty with urethral lengthening surgery between 2018 and 2021. Patients had stable urinary function via the neophallus at the time of survey. Patients filled out the PP UFT and were asked to record their PVUR as per our protocol. The average PP UFT score was 8.9 out of 40 and the average quality-of-life (QOL) score was 2.6. Postvoid dribbling constituted the major complaint and on average comprised 63.2% of the reported PP UFT score. The average PVUR was 2.2 ml (range: 0.5-5.6 ml). There was a positive correlation between higher PP UFT and worse-reported quality of life (P < 0.01; R2 = 0.4). Current questionnaires accepted in cis-male urology have limitations for accurately capturing urinary dysfunction in this specific patient group. The combination of PP UFT and PVUR measurement offers potential for quantifying urinary function and quality of life in patients who undergo phalloplasty. Future studies will validate these instruments.

RESUMO

Revision surgery after gender-affirming genitoplasty is becoming more and more common as more patients gain access to surgical treatment. The complexity of genitoplasty and extensive dissection of delicate tissues predisposes patients to necrosis of the flap(s) employed, which can leave patients with complications ranging from poor aesthetics to total lack of genital sensation. The purpose of this report is to detail the revision surgery of a 32-year-old transgender woman who underwent vaginoplasty at an outside institution and presented to our clinic for clitoral reconstruction following necrosis and near-total loss of the neoclitoris. Physical exam showed extensive necrosis, and 3-Tesla magnetic resonance (MRI) revealed significant scarring of the pudendal nerve branches at the level of the pubic symphysis. Healthy nerve was identified at the level of the right inferior pubic ramus, and total clitoral reconstruction with an innervated first dorsal web space free flap anastamosed to the deep inferior epigastric vessels was performed. Complications included donor site cellulitis with partial loss of the skin graft and formation of hypertrophic scar tissue. This was treated 6 months postoperatively with excision of scar tissue in the webspace and placement of an additional full-thickness skin graft. At follow-up, the patient reported tactile and erogenous sensation of the neoclitoris itself and subjective satisfaction with the aesthetic outcome. Our results provide evidence that this flap is a feasible option to create an aesthetic and sensate neoclitoris in the setting of previous neoclitoral necrosis. This case report also describes the novel use of 3-Tesla MRI in target selection for nerve coaptation.

RESUMO

The proliferation of fake news on social media is now a matter of considerable public and governmental concern. In 2016, the UK EU referendum and the US Presidential election were both marked by social media misinformation campaigns, which have subsequently reduced trust in democratic processes. More recently, during the COVID-19 pandemic, the acceptance of fake news has been shown to pose a threat to public health. Research on how to combat the false acceptance of fake news is still in its infancy. However, recent studies have started to focus on the psychological factors which might make some individuals less likely to fall for fake news. Here, we adopt that approach to assess whether individuals who show high levels of 'emotional intelligence' (EQ) are less likely to fall for fake news items. That is, are individuals who are better able to disregard the emotionally charged content of such items, better equipped to assess the veracity of the information. Using a sample of UK participants, an established measure of EQ and a novel fake news detection task, we report a significant positive relationship between individual differences in emotional intelligence and fake news detection ability. We also report a similar effect for higher levels of educational attainment, and we report some exploratory qualitative fake news judgement data. Our findings are discussed in terms of their applicability to practical short term (i.e. current Facebook user data) and medium term (i.e. emotional intelligence training) interventions which could enhance fake news detection.

RESUMO

The perceived value of our possessions extends well beyond their monetary worth or utility. Many possessions produce abiding attachments and contain deep conceptual meanings, which strongly influence our drive to acquire, retain, or relinquish them. In both the endowment effect and hoarding disorder (HD) research had focused on the degree that a fear of loss produces overvaluation by owners. There is evidence for this at both the behavioral and neural level, for example with self-reported negative emotions and activation in the insula and anterior cingulate cortex when one struggles to relinquish a good. However, there is also evidence from both fields that positive appraisals, motivations, and attachments participate in this process, with supporting activation in the dopaminergic mesolimbocortical system (e.g. nucleus accumbens and orbitofrontal cortex). These processes appear continuous between typical and clinical populations and with decisions about rewarding items in other contexts and species, such as food storing in rodents and offspring care in mammals. More research is needed on the degree that our attachment to and protection of goods reflect ancient neural systems for offspring care. We also need to study participants from other demographics and levels of wealth, and to consider how task framing shifts the proportion of associated negative and positive emotional states.

RESUMO

Empathy is a complex, multi-dimensional process. As such, it can be impaired at multiple stages, producing disorders of empathy with separable underlying causes. Studies often divide empathy into emotional and cognitive components to simplify the large space of empathic processes. This practice can be helpful, but also causes people to misunderstand their interdependence at the level of the mechanism and how they correspond to surveys and tasks. As a result, inferences made from experimental results are often incorrect and cannot be integrated across studies. We explain how emotional and cognitive empathy overlap through the proximate mechanism and clarify their operationalization in common surveys and tasks. A systematic review of three clinical disorders is used to highlight this issue and reinterpret and unite results according to the proximate framework--Borderline Personality Disorder (BPD), Narcissistic Personality Disorder (NPD), and Frontotemporal Dementia (FTD). Aligning constructs through the proximate mechanism allows us to understand both empathy and its disorders.

RESUMO

OBJECTIVES: Our first aim was to examine baseline differences in body dissatisfaction, depression, and anxiety symptoms by gender, age, and Tanner (ie, pubertal) stage. Our second aim was to test for changes in youth symptoms over the first year of receiving gender-affirming hormone therapy. Our third aim was to examine potential differences in change over time by demographic and treatment characteristics. Youth experiences of suicidal ideation, suicide attempt, and nonsuicidal self-injury (NSSI) are also reported. METHODS: Participants (n = 148; ages 9-18 years; mean age 14.9 years) were receiving gender-affirming hormone therapy at a multidisciplinary program in Dallas, Texas (n = 25 puberty suppression only; n = 123 feminizing or masculinizing hormone therapy). Participants completed surveys assessing body dissatisfaction (Body Image Scale), depression (Quick Inventory of Depressive Symptoms), and anxiety (Screen for Child Anxiety Related Emotional Disorders) at initial presentation to the clinic and at follow-up. Clinicians completed the Quick Inventory of Depressive Symptoms and collected information on youth experiences of suicidal ideation, suicide attempt, and NSSI. RESULTS: Affirmed males reported greater depression and anxiety at baseline, but these differences were small (P < .01). Youth reported large improvements in body dissatisfaction (P < .001), small to moderate improvements in self-report of depressive symptoms (P < .001), and small improvements in total anxiety symptoms (P < .01). No demographic or treatment-related characteristics were associated with change over time. Lifetime and follow-up rates were 81% and 39% for suicidal ideation, 16% and 4% for suicide attempt, and 52% and 18% for NSSI, respectively. CONCLUSIONS: Results provide further evidence of the critical role of gender-affirming hormone therapy in reducing body dissatisfaction. Modest initial improvements in mental health were also evident.

RESUMO

BACKGROUND: Mucosal appendicitis is a controversial entity that is histologically distinct from transmural appendicitis. There is mixed opinion regarding mucosal inflammation as a spectrum of appendicitis versus a negative appendectomy. The ability to distinguish these diagnoses preoperatively is of importance to prevent unnecessary surgery. We hypothesize that patients with mucosal appendicitis can be discriminated from those with transmural disease based on specific preoperative clinical and imaging findings. MATERIALS AND METHODS: After IRB approval, all patients who underwent laparoscopic appendectomy at our institution during 2015 were reviewed in the electronic medical record. Patients with mucosal appendicitis were identified and matched 2:1 to a random cohort of nonperforated transmural appendicitis cases. Demographic and clinical data were collected, including history, examination, laboratory, and imaging findings. Preoperative factors associated with mucosal appendicitis were modeled using binomial logistic regression analysis. RESULTS: Of 1153 appendectomies performed during 2015, 103 patients had pathologic diagnosis of mucosal appendicitis. When compared with patients with mucosal infection, leukocytosis >10,000 per microliter led to 5.9 times higher likelihood of transmural pathology (P = 0.000). Noncompressibility on ultrasound was associated with 7.3 times higher likelihood of transmural disease (P = 0.015). Echogenic changes were predictive of transmural appendicitis, conferring 3.9 times the risk (P = 0.007). Presence of free fluid led to 2.3 times the rate of transmural pathology (P = 0.007). Finally, for every millimeter decrease in appendiceal diameter, patients were half as likely to exhibit transmural disease (P = 0.000). Together, these variables can successfully predict presence of mucosal appendicitis on final pathology report at a rate of 82.1%, and explain 60% of the variance in diagnosis of mucosal versus transmural appendicitis (P = 0.000). CONCLUSIONS: Mucosal appendicitis remains a controversial pathologic entity, but is not associated with greater complications compared with transmural appendicitis when treated with laparoscopic appendectomy. Transmural disease can be predicted by leukocytosis, noncompressible appendix, presence of free fluid, larger appendiceal diameter and echogenicity.

RESUMO

BACKGROUND: Diagnostic imaging in pediatric appendicitis may decrease rates of negative appendectomy and identify alternate pathologies. We compared imaging practices for children transferred from nonpediatric facilities versus directly admitted to our tertiary children's hospital for laparoscopic appendectomy, and assessed the diagnostic accuracy in each population based on final pathologic diagnosis. MATERIALS AND METHODS: After institutional review board approval, all cases of laparoscopic appendectomy at our children's hospital during 2015 were reviewed. Demographic and clinical data were collected, including age, transfer status, imaging studies, and pathologic diagnosis. Imaging practices in patients transferred from adult centers were compared with those directly admitted. RESULTS: There were 1153 included patients who underwent laparoscopic appendectomy for acute appendicitis during the study period, with 242 (20.9%) presenting as transfers from nonpediatric facilities. Of these, 73.5% underwent preoperative computed tomography (CT), compared with 26.4% of nontransfer patients (P < 0.000). All remaining patients received ultrasound (US). Despite variation in imaging strategies, rates of negative appendectomy were similar in transfer and nontransfer groups (1.7% versus 2.0%, respectively, P = 0.744). There were marginal differences in sensitivity of US and CT to detect appendix features between the transferring and referral centers. CONCLUSIONS: Our results show that nonpediatric facilities use CT more frequently to diagnose pediatric appendicitis. Rates of nontherapeutic surgery were equivalent between transferred and directly admitted patients, which is likely related to high performance of both imaging strategies. Transferring centers should strive to rely more heavily on US, which may require education and development of improved pediatric US capacity.
