RESUMEN
During early embryogenesis in amniotic vertebrates, the gonads differentiate into either ovaries or testes. The first cell lineage to differentiate gives rise to the supporting cells: Sertoli cells in males and pre-granulosa cells in females. These key cell types direct the differentiation of the other cell types in the gonad, including steroidogenic cells. The gonadal surface epithelium and the interstitial cell populations are less well studied, and little is known about their sexual differentiation programs. Here, we show the requirement of the homeobox transcription factor gene TGIF1 for ovarian development in the chicken embryo. TGIF1 is expressed in the two principal ovarian somatic cell populations: the cortex and the pre-granulosa cells of the medulla. TGIF1 expression is associated with an ovarian phenotype in estrogen-mediated sex reversal experiments. Targeted misexpression and gene knockdown indicate that TGIF1 is required, but not sufficient, for proper ovarian cortex formation. In addition, TGIF1 is identified as the first known regulator of juxtacortical medulla development. These findings provide new insights into chicken ovarian differentiation and development, specifically cortical and juxtacortical medulla formation.

BACKGROUND: The optimal assessment of systemic and lung decongestion during acute heart failure is not clearly defined. We evaluated whether inferior vena cava (IVC) and pulmonary ultrasound (CAVAL US) guided therapy is superior to standard care in reducing subclinical congestion at discharge in patients with AHF. METHODS: CAVAL US-AHF was an investigator-initiated, single-center, single-blind, randomized controlled trial. A daily quantitative ultrasound protocol using the 8-zone method was used and treatment was adjusted according to an algorithm. The primary endpoint was the presence of more than 5 B-lines and/or an increase in IVC diameter and collapsibility at discharge. And secondary endpoint exploratory outcome was the composite of readmission for HF, unplanned visit for worsening HF or death at 90 days RESULTS: Sixty patients were randomized to CAVAL US (n = 30) or control (n = 30). The primary endpoint was achieved in 4 patients (13.3%) in the CAVAL US group and 20 patients (66.6%) in the control group (P < .001). A significant reduction in HF readmission, unplanned visit for worsening HF or death at 90 days was seen in the CAVAL US group (13.3% vs 36.7%; log rank P = .038). Other endpoints such as NT-proBNP reduction at discharge showed a nonstatistically significant reduction in the CAVAL US group (48% IQR 27-67 vs 37% -3-59; P = .09). Safety outcomes were similar in both groups. CONCLUSION: IVC and lung ultrasound-guided therapy in AHF patients significantly reduced subclinical congestion at discharge. CAVAL US-AHF provides preliminary evidence for the potential use of a simple technique to guide decongestive therapy during hospitalization for AHF, which may reduce the composite outcome at 90 days.
RESUMEN
OBJECTIVE: Although the presence of neuropathic pain (NP) components has been reported in whiplash-associated disorders (WAD), no studies have analyzed the usefulness of NP screening questionnaires to detect NP components in WAD. This study aimed to assess the usefulness of 3 NP screening tools (Douleur Neuropathique 4 [DN4], self-administered Leeds Assessment of Neuropathic Symptoms and Signs [S-LANSS], and painDETECT questionnaire [PDQ]) to detect the presence of NP components in acute WAD. DESIGN: A cross-sectional study. SETTING: Hospital. SUBJECTS: Of 188 eligible individuals, 50 people (68% women, mean age = 40.3 ± 12.5 years) with acute WAD (52% Grade III) were included. METHODS: Specialized physicians initially screened participants for the presence of NP components according to clinical practice and international recommendations. After physician assessment, blinded investigators used NP screening questionnaires (DN4, S-LANSS, and PDQ) to assess participants within 2 weeks of their accident. The diagnostic accuracy of these tools was analyzed and compared with the reference standard (physicians' assessments). RESULTS: The 3 screening questionnaires showed excellent discriminant validity (area under the curve: ≥0.8), especially S-LANSS (area under the curve: 0.9; P < .001). DN4 demonstrated the highest sensitivity (87%), followed by S-LANSS (75%), while S-LANSS and PDQ showed the highest specificity (85% and 82%, respectively). These tools demonstrated a strong correlation with the reference standard (S-LANSS: rho = 0.7; PDQ: rho = 0.62; DN4: rho = 0.7; all, P < .001). CONCLUSIONS: The DN4, S-LANSS, and PDQ show excellent discriminant validity to detect the presence of NP components in acute WAD, especially S-LANSS. Initial screening with these tools might improve management of WAD.

It is commonly necessary to perform inferences on the difference, ratio, and odds ratio of two proportions p1 and p2 based on two independent samples. For this purpose, the most common asymptotic statistics are based on the score statistics (S-type statistics). As these do not correct the bias of the estimator of the product pi (1-pi), Miettinen and Nurminen proposed the MN-type statistics, which consist of multiplying the statistics S by (N-1)/N, where N is the sum of the two sample sizes. This paper demonstrates that the factor (N-1)/N is only correct in the case of the test of equality of two proportions, providing the estimation of the correct factor (AU-type statistics) and the minimum value of the same (AUM-type statistics). Moreover, this paper assesses the performance of the four-type statistics mentioned (S, MN, AU and AUM) in one and two-tailed tests, and for each of the three parameters cited (d, R and OR). We found that the AUM-type statistics are the best, followed by the MN type (whose performance was most similar to that of AU-type). Finally, this paper also provides the correct factors when the data are from a multinomial distribution, with the novelty that the MN and AU statistics are similar in the case of the test for the odds ratio.
RESUMEN
School refusal (SR) is a form of school attendance problem (SAP) that requires specific mental health care. Despite improvements in the definition of SAPs, the course of SR is not well characterized. To explore three-year patterns of SR course in children, as reported by their parents, we deployed an anonymous web-based survey. We defined SR onset as the absence of ≥ 2 school weeks during one academic year, combined with emotional distress. We defined standard SR trajectories using sequence analysis of parents' recollection of three consecutive years of school attendance. We obtained 1970 responses, 1328 (67%) completed by a parent and meeting the definition of SR. Of these, 729 (55%) responses included three years of school attendance recollection. We identified five prototypical trajectories of SR: two profiles for children: beaded absences (n = 272), and rapid recovery (n = 132); and three for adolescents: prolonged recovery (n = 93), gradual decline (n = 89), and rapid decline (n = 143). We found five distinct trajectories of retrospective recall of SR course. Through pattern recognition, this typology could help with timely identification of SR and implementation of evidence-based interventions to optimize outcomes. Prospective replication of these findings and their field application is warranted.
RESUMEN
PURPOSE: Develop and assess a novel medical improvisation-based motivational interviewing (MI) curriculum for residents. MATERIALS AND METHODS: A 6-h medical improv-based MI curriculum occurred in 2022 for internal medicine residents. A mixed-methods evaluation included: pre- and post-role plays using the Motivational Interviewing Treatment Integrity Score (MITI) to assess MI competency, a post-course survey assessing confidence, and focus groups to understand learning through improvisation. RESULTS: Participants increased their confidence in applying MI skills after the curriculum in responding to a patient's argument against change (29% pre vs. 72% post, p < 0.001), eliciting change talk (21% vs. 86%, p < 0.001), and providing information in an MI-centric way (39% vs. 86%, p < 0.001). All role-play participants achieved at least beginning proficiency on MITI technical and relational global summary scores post-course. MI-adherent behaviors increased, and MI-non-adherent behaviors decreased in post-course role plays. Themes on learning through improvisation included: (1) improvisation can enhance the learning of MI skills, (2) using non-medical scenarios in improvisation exercises has benefits, and (3) trying improvisation had positive effects on the learning environment. DISCUSSION: A medical improvisation-based course is a promising, engaging way to teach residents MI skills and can improve competence and confidence with MI.

OBJECTIVE: There is a shortage of psychiatrists necessary to meet the clinical needs of children and adolescents. Efforts over the past decade to enhance the workforce have had a limited impact. This study sought to identify the critical components of a medical student mentorship network designed to increase recruitment into the subspecialty. METHODS: The authors conducted interviews via synchronized videoconferencing of network site leaders and medical students at 14 schools throughout the USA. In addition, they analyzed verbatim transcripts using a thematic-phenomenological qualitative approach. RESULTS: The authors interviewed thirty-eight program participants during seven focus group sessions: nine program directors and 29 medical students or graduates, a median of five participants per session. They constructed a framework consisting of two overarching domains, comprised of three themes each: (1) life cycle of a subspecialty mentorship network (Origins, Initiation, and Continuity); and (2) next steps to improve the program (Refining goals, Increasing accessibility, and Defining a path forward). CONCLUSION: Preliminary data have already documented the positive impact of participation in this mentorship program on medical student match rates into psychiatry. The qualitative model of this study provides a blueprint to develop, maintain, and optimize this and similar efforts aimed at increasing the child and adolescent psychiatry workforce.

Interpersonal communication is critical in training, licensing, and post-graduate maintenance of certification in veterinary medicine. Simulation has a vital role in advancing these skills, but even sophisticated simulation models have pedagogic limitations. Specifically, with learning goals and case scenarios designed by instructors, interaction with simulated participants (SPs) can become performative or circumscribed to evaluative assessments. This article describes co-constructive veterinary simulation (CCVS), an adaptation of a novel approach to participatory simulation that centers on learner-driven goals and individually tailored scenarios. CCVS involves a first phase of scriptwriting, in which a learner collaborates with a facilitator and a professional actor in developing a client-patient case scenario. In a second phase, fellow learners have a blinded interaction with the SP-in-role, unaware of the underlying clinical situation. In the final part, all learners come together for a debriefing session centered on reflective practice. The authors provide guidelines for learners to gain maximal benefit from their participation in CCVS sessions and describe thematic possibilities to incorporate into the model, with specific case examples drawn from routine veterinary practice. Finally, the authors outline challenges and future directions toward implementing CCVS in veterinary medical education toward the ultimate goal of professional growth and co-evolution as veterinary practitioners.

BACKGROUND: Confronting stigma early in life could enhance receptivity to seeking treatment. We evaluated the efficacy of social contact interventions to reduce stigma toward depression and to enhance treatment-seeking intentions among adolescents. We hypothesized that the brief video-based interventions would be more effective than their matched controls. METHOD: Using crowdsourcing, we recruited and randomly assigned 1,183 participants aged 14-18 to one of four video-based stimuli on a 4:4:1:1 ratio: (a) adolescent girl with depression; (b) adolescent boy with depression; (c) same girl, without depression; or (d) same boy, without depression. In each of the ~100-second-long videos, two simulated patients (SPs) depicted empowered presenters sharing their personal stories. In the depression conditions, SPs described how social support from family, friends, and professionals helped them overcome their symptoms and recover. RESULTS: We found a significant effect for the Depression Stigma Scale (DSS) between active and control groups (F = 27.4, p < .001). We found a significant increase in treatment-seeking intentions, as measured by the General Help-Seeking Questionnaire (GHSQ; p < .001). Secondary analyses revealed that racial (but not gender) congruence between protagonists and participants resulted in greater stigma reduction and treatment seeking, as compared to racially incongruent pairings (t = 2.9, p = .004). CONCLUSION: A brief video-based intervention effectively reduced stigma toward depression and increased treatment seeking among adolescents. Favorable changes were greater when race (but not gender) was congruent between protagonists and participants. Future studies should explore how to optimize brief contact-based interventions according to adolescents' race and ethnicity and how to scale such interventions to novel online platforms of dissemination.

OBJECTIVE: To test the utility of brief social contact-based video interventions of a Black adolescent girl to reduce stigmatized attitudes and increase help-seeking intentions around adolescent depression. METHODS: We conducted a randomized controlled trial (RCT) with 14- to18-year-old healthy volunteers drawn from the general US population. We enrolled participants through a crowdsourcing platform (n = 1,093) and randomly assigned participants to one of three video conditions (117 s each): depressed (DEP); depressed, adjusted to aspects unique to being a Black adolescent girl (including experienced or internalized racism; ADJ); and control (CONT). The primary outcome was the Depression Stigma Scale (DSS); secondary outcomes were the General Health-Seeking Questionnaire (GHSQ), and thermometers for Black and white race perception "warmth". RESULTS: Following the intervention, the DSS changed from baseline across the three conditions (p < .001). ADJ outperformed both DEP (p = .031) and CONT (p < .001). A race-by-intervention interaction (p < .001) revealed different response profiles between Black (ADJ = DEP = CONT; p = .726) and non-Black participants (ADJ > DEP > CONT; p < .001). DEP and ADJ both resulted in higher treatment-seeking intentions for both the emotional problems and the suicidal thought subscales of the GHSQ. We found a race-by-intervention interaction (p = .01) for the Black thermometer, which revealed a significant 2° increase in warmth among white (p < .001), but not Black, viewers (p = .06). CONCLUSIONS: On a short-term basis, brief social contact-based videos proved effective among adolescents in reducing depression-related stigma, increasing help-seeking intentions, and providing an "empathic foothold" in the lives of racially stigmatized groups. Even as the enduring effects of these interventions remain to be determined, the deployment on social media of short videos opens new opportunities to reach a large number of at-risk youth."

We assessed how rod excitation (R) affects luminance (L + M + S) and chromatic [L/(L + M)] reaction times (RTs). A four-primary display based on the overlapped images of two spectrally modified monitors, which allowed specific or combined [L + M + S + R, L/(L + M) + R] photoreceptor stimulation, was used to present a C-target stimulus differing from the background only by the selected stimulation. For the luminance pathway, rod input increased RTs, suggesting a suppressive rod-cone interaction. The responses of the chromatic pathway were faster when rods were involved, suggesting a major role of rods in mesopic color perception.

BACKGROUND: In collaboration with members of the transgender and gender diverse (TGD) community, we created a didactic resource about the unique needs of TGD youth. METHODS: We developed teaching materials enhanced by video clips of two TGD adolescents openly sharing aspects of their lived experience. We compared the video and no video conditions in a randomized controlled trial (RCT) in which participants were assigned to one of four parallel conditions: 1) a transgender [TgV] or 2) a cisgender [CgV] woman presenting with videos embedded into the presentation, 3) the same cisgender woman presenting without the videos [CgN], or 4) a no intervention control [NiC]. Our primary outcome was change in the total score of the Transgender Knowledge, Attitudes, and Beliefs Scale (T-KAB). RESULTS: We recruited and proportionally randomized 467 individuals, 200 of whom completed ratings before and after the intervention: TgV (n = 46), CgV (N = 46), CgN (n = 44), and NiC (n = 64). Mean scores on all measures of TGD acceptance increased in the video group, compared to the no video group. Improvements persisted after 30 days (p < 0.01), except on perceptions about TGD family members. The three active intervention groups did not differ in efficacy. CONCLUSIONS: These findings provide empirical evidence that a well-informed presenter, regardless of their gender, can achieve similar improvements in perceptions and knowledge about TGD youth when using a resource that can be disseminated free of cost.

BACKGROUND AND OBJECTIVE: Premature skin ageing, and skin hyperpigmentation are influenced by exogenous factors, such as ultraviolet radiation and blue light. In this study, we assess the protective effect of a sunscreen (TDF® Blu Voile Sunscreen) in protecting the skin against the harmful effects of blue light irradiation in vivo and through the in situ quantitative and qualitative evaluation of protein carbonylation in human skin explants. METHODOLOGY: The protective effect of the test product against blue light was first evaluated ex vivo on human skin explants. The treated and non-treated explants were exposed to 14 J/cm2 of blue light 460 nm following which the protein carbonylation was evaluated by in situ epifluorescence imaging and separation by high-resolution gel electrophoresis. To determine whether the test product could also protect against the immediate and persistent pigmenting effect of blue light, two randomized in vivo studies were conducted, which included respectively 17 subjects with a skin phototype of IV and V (Fitzpatrick classification) and 22 subjects with a skin phototype of IV, V, and VI (Fitzpatrick classification). The duration of the study for each subject was 2 days (D1 and D2) for immediate observations and 5 days (D1-D5) for persistent observations. Specific zones on the subjects' back were either left non-treated or treated with the test product and were then exposed to a unique dose of blue light 415 nm. The onset of pigmentation between the treated and exposed zones was then assessed relative to the non-exposed treated zone through colorimetric measurements of the Individual Typology Angle (ITAo ). RESULTS: Human skin explants treated with test product showed significantly lower levels of accumulated carbonylated proteins, with a protection of 82%, following exposure to blue light 460 nm. Findings of the in vivo studies also indicated that the test product presented significantly better protective efficacy against immediate and persistent pigmentation induced by blue light 415 nm. CONCLUSION: Hence, it can be concluded that the test product can protect against the oxidative stress as well as the immediate and persistent pigmentation induced by blue light.
CONTEXTE ET OBJECTIF: Le vieillissement prématuré de la peau et l'hyperpigmentation cutanée sont influencés par des facteurs exogènes, tels que les rayons ultraviolets et la lumière bleue. Dans cette étude, nous évaluons l'effet protecteur d'un écran solaire (TDF® Blu Voile Sunscreen) en matière de protection de la peau contre les effets nocifs de l'irradiation à la lumière bleue in vivo et par l'évaluation quantitative et qualitative in situ de la carbonylation des protéines dans des explants cutanés humains. MÉTHODOLOGIE: L'effet protecteur du produit testé contre la lumière bleue a d'abord été évalué ex vivo sur des explants cutanés humains. Les explants traités et non traités ont été exposés à 14 J/cm2 de lumière bleue à 460 nm, après quoi la carbonylation des protéines a été évaluée par imagerie par épifluorescence in situ et séparation par électrophorèse sur gel à haute résolution. Afin de déterminer si le produit testé pouvait également protéger contre la pigmentation immédiate et persistante dues à lumière bleue, deux études in vivo randomisées incluant respectivement 17 sujets ayant un phototype cutané IV et V (classification de Fitzpatrick) et 22 sujets ayant un phototype cutané IV, V et VI (classification de Fitzpatrick) ont été menées. La durée de l'étude pour chaque sujet était de 2 jours (J1 et J2) pour les observations immédiates et de 5 jours (J1 à J5) pour les observations persistantes. Des zones spécifiques du dos des sujets ont été laissées non traitées ou bien traitées avec le produit testé, et ont ensuite été exposées à une dose unique de lumière bleue à 415 nm. L'apparition de la pigmentation entre les zones traitées et exposées a ensuite été évaluée par rapport à la zone traitée non exposée par des mesures colorimétriques de l'angle typologique individuel (Individual Typology Angle, ITAo). RÉSULTATS: Les explants cutanés humains traités avec le produit testé ont montré des taux significativement plus faibles de protéines carbonylées accumulées, avec une protection de 82 %, après une exposition à la lumière bleue à 460 nm. Les résultats des études in vivo ont également indiqué que le produit testé présentait une efficacité protectrice significativement meilleure contre la pigmentation immédiate et persistante induite par la lumière bleue à 415 nm. CONCLUSION: Par conséquent, on peut conclure que le produit testé peut protéger contre le stress oxydatif ainsi que contre la pigmentation immédiate et persistante induite par la lumière bleue.

OBJECTIVE: The authors developed and tested video clips depicting three paradigmatic substance use disorder (SUD) clinical scenarios, each portrayed by a different simulated patient interacting with the same clinician. METHODS: The authors embedded 21 short video clips (with a cumulative duration of 27 min) into a 2-h session on SUDs. The didactic was delivered online through synchronous videoconferencing with Zoom. The primary outcome compared learners' scores on the Attitudes and Confidence in the Treatment of Patients with Substance Use Disorders (ACT-SUDS) before and after participating in the didactic. RESULTS: Fifty-eight second-year medical students participated and completed the survey prior to the didactic; 42 (72%) of them completed the survey immediately after. Compared to baseline, ACT-SUDS increased after the didactic: from 3.7 ± 0.5 to 4.0 ± 0.4 (mean difference = 0.4 [95% confidence interval = 0.2-0.5], paired-t = 5.75, p < 0.001), as did each of its four subscales: confidence, enjoyment, SUD as a medical disorder, and attitudes toward Alcoholics Anonymous (AA; t ≥ 3.0, p ≤ 0.005). CONCLUSIONS: The video-based educational module proved easy to implement in the virtual classroom and led to measurable changes in perceptions and attitudes toward SUDs. The module is available to view or freely download and is amenable for adaptation by end-use instructors.

OBJECTIVE: This study describes the supply, distribution, and characteristics of international medical graduate (IMG) psychiatrists who provide services in the USA. METHODS: Cross-sectional study design, using descriptive statistics based on combined data from the American Medical Association (2020 Physician Masterfile) and the Educational Commission for Foreign Medical Graduates. RESULTS: International medical graduates continue to make significant contributions to the US physician workforce. As a group, they represent 29% of active psychiatrists in the USA, compared to 23% in all other medical specialties. Many IMG psychiatrists were US citizens who obtained their medical degrees outside the USA or Canada, often in the Caribbean. In some states (i.e., Florida, New Jersey), over 40% of active psychiatrists are IMGs. Over 30% of IMG psychiatrists graduated from medical schools in India and Pakistan. CONCLUSIONS: This study provides an overview of the psychiatric workforce in the USA, quantifying the specific contribution of IMGs. Several factors, including immigration policies, continued expansion of US medical schools, and the number of available residency positions, could impact the flow of IMGs to the US. Longitudinal studies are needed to better understand the implications for workforce composition and distribution, and their potential impact on the care of psychiatric patients.

OBJECTIVE: Since 2002, the Klingenstein Third Generation Foundation (KTGF) has supported a network of medical student mentorship programs (MSMPs) across the USA with the explicit aim of enhancing interest in, and eventual recruitment into the field of child and adolescent psychiatry (CAP). The authors conducted a multisite, retrospective cohort analysis to examine the impact of the program on career selection, as reflected by graduation match rates into psychiatry or pediatrics. METHODS: The authors collected graduating match information (2008-2019) from fourteen participating medical schools (Exposed) and thirteen non-participating schools (Control). Control schools were selected based on region, comparable student body and faculty size, national standing, and rank in NIH funding. Match rates into psychiatry and pediatrics were compared between Exposed and Control groups. RESULTS: Exposed schools had significantly higher match rates into psychiatry as compared to unexposed schools (6.1% and 4.8%, respectively; OR [95%CI] = 1.29 [1.18, 1.40]; X2 = 32.036, p < 0.001). In contrast, during the same time period, exposed schools had significantly lower match rates into pediatrics than unexposed ones (11.6 and 10.5%, respectively; OR [95%CI] = 0.89 (0.83, 0.95); X2 = 12.127, p < 0.001). These findings persisted even after adjustment for secular trends in match rates. CONCLUSIONS: Seventeen years after its inception, the KTGF medical student mentorship program network has had a positive impact on match rates into general psychiatry. Future studies will address whether these results translate to trainees' eventual selection of careers in CAP.

BACKGROUND: Despite the growing impact of climate change on mental health, there have been few studies to date investigating how children and teenagers manage their ecological grief and eco-anxiety and how they can leverage it into environmental action. In this scoping review, we analyze lay press narratives about how youth respond to climate change to examine the dynamics between minors and adults around the evolving climate crisis. METHODS: We included articles published between 2018 and 2021 in six of the top ten American newspapers by circulation about young people during the climate crisis. The 131 articles we selected addressed the attitudes of children, adolescents, and parents toward the climate crisis. We conducted a qualitative analysis based on discourse analysis aided by NVivo software. RESULTS: Newspaper articles commonly categorized children, adolescents, and their respective perspectives and experiences around climate change along four patterns of discourse: (a) fierce young activists; (b) adultified children; (c) innocent victims; and/or (d) ultimate saviors. In turn, articles considered parents and adults in one of four paradigmatic ways: (a) experiencing eco-anxiety through parenthood; (b) taming children's eco-anxiety; (c) criticizing youth-led activism; and/or (d) reimagining climate action as a source of meaning in the lives of young people. CONCLUSION: Through the framework of childism, or prejudice against children, we conceptualize immature ways for adults to respond to youths' concerns as a defensive stance against overwhelming climate change anxiety. Alternatively, principles of existential psychology can help inform healthier and more productive responses from parents, clinicians, educators, and public health officials as they seek truthful yet supportive responses to address legitimate ecological threats that will disproportionately affect generations to come.

BACKGROUND: Knowledge gaps and stigmatized perceptions regarding electroconvulsive therapy (ECT) among patients and health providers contribute to the underutilization of an important therapeutic modality. The proactive education of future advanced practice registered nurses (APRNs) provides an opportunity to optimize the use of this evidence-based clinical practice. AIMS: As part of a general course in psychiatry during the first year of nursing school, we dedicated 1 hour to treatment-refractory depression, including ECT, and a second hour to a summary discussion of mood disorders. We evaluated the efficacy of this didactic offering, which was co-taught by a psychiatrist and a psychiatric APRN. METHOD: At baseline, consenting students (n = 94) provided three words they associated with ECT and then completed three validated instruments: (a) Questionnaire on Attitudes and Knowledge of ECT, (b) Opening Minds Stigma Scale for Health Care Providers, and (c) Self-Stigma of Seeking Help. Among the 67 students who repeated the assessment at endpoint, 39 attended the ECT didactic (Intervention group, 58%) and 28 did not (Control, 42%). RESULTS: After completion of the 3-month course, students showed improvement across all measures (p < .001). The only outcomes that improved differentially between the Intervention and Control groups were the Questionnaire on Attitudes and Knowledge of ECT Attitudes and Knowledge scales (p = .01). Word choice valence associated with ECT shifted favorably by endpoint (p < .001). CONCLUSIONS: An educational intervention co-led by a psychiatric-mental health APRN had a significant impact on nursing students' knowledge and perceptions of ECT. This approach can be readily implemented at other institutions. Future refinements will include the videotaped depiction of a simulated patient undergoing the consent, treatment, and recovery phases of ECT.

OBJECTIVE: To define "best possible" outcomes for secondary bariatric surgery (BS). BACKGROUND: Management of poor response and of long-term complications after BS is complex and under-investigated. Indications and types of reoperations vary widely and postoperative complication rates are higher compared to primary BS. METHODS: Out of 44,884 BS performed in 18 high-volume centers from 4 continents between 06/2013-05/2019, 5,349 (12%) secondary BS cases were identified. Twenty-one outcome benchmarks were established in low-risk patients, defined as the 75th percentile of the median outcome values of centers. Benchmark cases had no previous laparotomy, diabetes, sleep apnea, cardiopathy, renal insufficiency, inflammatory bowel disease, immunosuppression, thromboembolic events, BMI>â50âkg/m2 or age>â65âyears. RESULTS: The benchmark cohort included 3143 cases, mainly females (85%), aged 43.8â±â10âyears, 8.4â±â5.3âyears after primary BS, with a BMI 35.2â±â7âkg/m2. Main indications were insufficient weight loss (43%) and gastro-esophageal reflux disease/dysphagia (25%). 90-days postoperatively, 14.6% of benchmark patients presented ≥1 complication, mortality was 0.06% (n = 2). Significantly higher morbidity was observed in non-benchmark cases (OR 1.37) and after conversional/reversal or revisional procedures with gastrointestinal suture/stapling (OR 1.84). Benchmark cutoffs for conversional BS were ≤4.5% re-intervention, ≤8.3% re-operation 90-days postoperatively. At 2-years (IQR 1-3) 15.6% of benchmark patients required a reoperation. CONCLUSION: Secondary BS is safe, although postoperative morbidity exceeds the established benchmarks for primary BS. The excess morbidity is due to an increased risk of gastrointestinal leakage and higher need for intensive care. The considerable rate of tertiary BS warrants expertise and future research to optimize the management of non-success after BS.

Modelling the influence of age on the perception of brightness of visual stimuli is an important topic for indoor and outdoor lighting. As people get older, the transmittance of the ocular media becomes lower, especially in the blue wavelength region. This paper reports on an experimental study aiming to evaluate how the brightness perception of red and blue stimuli is affected by the age of the observer. A matching experiment has been set up in which both young (25 years old on average) and older (70 years old on average) adult observers had to match the brightness of a blue stimulus with the brightness of a red stimulus, both surrounded by a dark background (unrelated stimuli). A significant difference in brightness perception between the two groups of observers was found. In particular, older people report a decrease in brightness perception for the blue stimuli compared to younger people. The results show that the brightness correlate of the colour appearance model CAM18sl (applied with zero luminance background) adequately predicts the matching results of young observers, but failed to predict the results obtained by the older observers. As CAM18sl is built on cone fundamentals which include the transmittance of the ocular media and consider the age of the observer as an input parameter, the authors developed the idea to substitute the cone fundamentals for a young observer by the cone fundamentals for a 70 years old observer. This updated CAM18sl performed very well for the older observer as well, on condition that the transmittance of the ocular media is isolated and kept out of the normalization of the cone fundamentals.
