    Abstract A small subset of males presenting with cryptorchidism are found to have ectopic testes. The most common location for an ectopic testicle is the superficial inguinal pouch, but there are several other possibilities, necessitating a thorough physical exam. A 4-month-old term male presented for evaluation of a nonpalpable right testicle. Examination revealed an ectopic right testicle located in the perineum. The patient underwent successful right orchiopexy. Ectopic testes are rare but remain in the differential diagnoses for patients with cryptorchidism. Patients should undergo prompt orchiopexy to avoid potential complications and allow maximal preservation of testicular function.

    Abstract Objective: Previous literature has indicated a strong negative correlation between the moral foundation of purity/sanctity and vaccination rates. The current research investigated how purity concerns impact COVID-19 vaccination hesitancy and tested an information intervention to bolster vaccination intention among people with purity concerns.
    Method: Study 1 surveyed 566 Republicans and Republican-leaning Independents in the United States. Study 2 was a between-subject-designed survey experiment that investigated the impact of three statements on the COVID-19 vaccination attitudes and intentions of 637 Republicans and Republican-leaning Independents. Statement 1 argued that vaccines are not impure from a scientific perspective; Statement 2 made the same argument with quotes from the Bible; and Statement 3 was a control statement.
    Results: Study 1 established a significant correlation between the existence of vaccination history and purity as a moral foundation. Study 2 found that among those with no COVID-19 vaccination history, statements arguing that vaccines are not impure from either a scientific perspective or a religious perspective improved attitudes toward vaccination and intention to get vaccinated.
    Conclusion: Purity concerns can be leveraged as a way to bolster vaccination rates, especially among conservatives. However, the impurity perception only mediated the causal relationship between the treatment and the attitude toward vaccines (but not the actual intention), suggesting that changes in the actual vaccination behavior are subject to factors other than purity concerns.

    Abstract Background and aims: Interns must be proficient in obtaining informed consent (IC), which is the Association of American Medical College's 11th of 13 Entrustable Professional Activities (EPAs). Medical students have limited opportunity to practice IC during clerkships, resulting in inconsistent proficiency. We aimed to create a tool to assess whether our transition to residency (TTR) workshop enables fourth-year medical students to meet a minimum standard of obtaining IC.
    Methods: Sixty fourth-year medical students were enrolled in the internal medicine virtual TTR course during AY2021. The curriculum prioritizes deliberate practice activities. Pre- and postworkshop assignments involved students typing verbatim what they would say during IC encounters. We modified an IC abstraction tool created by Spatz et al. to assess a minimum standard for students' IC assignments. Our final 7-item tool consisted of the following domains: "What," "Why," "How," "Benefits," "Quantitative Risks," "Qualitative Risks," and "Alternatives," weighing 1 point each. A minimum standard was obtained with a score of 6 or more points by appropriately discussing at least one domain involving risk and all other domains.
    Results: Students scored highly on the prework domains pertaining to "What," "Why," and "How" of the procedure with no significant difference on postwork. Significant improvement was achieved on postwork domains covering "Benefits" (
    Conclusion: Our students demonstrated a good a priori understanding of the "What," "Why," and "How" domains. After the workshop, they more reliably discussed "Benefits" and "Alternatives." Our abstraction tool helped assess the strengths and weaknesses in our students' IC skillset and helped recognize areas of our curriculum that will benefit from improvements to bring students to meet the minimum standard.

    Abstract Explainable Information Retrieval (XIR) is a growing research area focused on enhancing transparency and trustworthiness of the complex decision-making processes taking place in modern information retrieval systems. While there has been progress in developing XIR systems, empirical evaluation tools to assess the degree of explainability attained by such systems are lacking. To close this gap and gain insights into the true merit of XIR systems, we extend existing insights from a factor analysis of search explainability to introduce SSE (Search System Explainability), an evaluation metric for XIR search systems. Through a crowdsourced user study, we demonstrate SSE's ability to distinguish between explainable and non-explainable systems, showing that systems with higher scores indeed indicate greater interpretability. Additionally, we observe comparable perceived temporal demand and performance levels between non-native and native English speakers. We hope that aside from these concrete contributions to XIR, this line of work will serve as a blueprint for similar explainability evaluation efforts in other domains of machine learning and natural language processing.

    Abstract Language comprehension involves integrating low-level sensory inputs into a hierarchy of increasingly high-level features. Prior work studied brain representations of different levels of the language hierarchy, but has not determined whether these brain representations are shared between written and spoken language. To address this issue, we analyze fMRI BOLD data that were recorded while participants read and listened to the same narratives in each modality. Levels of the language hierarchy are operationalized as timescales, where each timescale refers to a set of spectral components of a language stimulus. Voxelwise encoding models are used to determine where different timescales are represented across the cerebral cortex, for each modality separately. These models reveal that between the two modalities timescale representations are organized similarly across the cortical surface. Our results suggest that, after low-level sensory processing, language integration proceeds similarly regardless of stimulus modality.

    Abstract Objectives: Few data on alveolar hypoventilation in Prader-Willi syndrome (PWS) are available and the respiratory follow-up of these patients is not standardized. The objectives of this study were to evaluate the prevalence of alveolar hypoventilation in children with PWS and identify potential risk factors.
    Study design: This retrospective study included children with PWS recorded by polysomnography (PSG) with transcutaneous carbon dioxide pressure (PtcCO2) or end-tidal CO2 (ETCO2) measurements, between 2007 and 2021, in a tertiary hospital center. The primary outcome was the presence of alveolar hypoventilation defined as partial pressure of carbon dioxide (pCO2) ≥ 50 mmHg during ≥2% of total sleep time (TST) or more than five consecutive minutes.
    Results: Among the 57 included children (38 boys, median age 4.8 years, range 0.1-15.6, 60% treated with growth hormone [GH], 37% obese), 19 (33%) had moderate-to-severe obstructive sleep apnea syndrome (defined as obstructive apnea-hypopnea index ≥5/h) and 20 (35%) had hypoventilation. The median (range) pCO2 max was 49 mmHg (38-69). Among the children with hypoventilation, 25% were asymptomatic. Median age and GH treatment were significantly higher in children with hypoventilation compared to those without. There was no significant difference in terms of sex, BMI, obstructive or central apnea-hypopnea index between both groups.
    Conclusion: The frequency of alveolar hypoventilation in children and adolescents with PWS is of concern and may increase with age and GH treatment. A regular screening by oximetry-capnography appears to be indicated whatever the sex, BMI, and rate of obstructive or central apneas.
