Messaging About HIV Transmission Risk When Viral Load Is Undetectable: Reactions and Perceived Accuracy Among US Sexual Minority Men.

BACKGROUND: Scientific evidence indicates that HIV viral suppression to an undetectable level eliminates sexual transmission risk ("Undetectable=Untransmittable" or "U=U"). However, U=U messaging has been met with skepticism among sexual minority men (SMM) and others. In this survey-based experiment, we manipulated messaging about HIV risk and examined reactions and perceived message accuracy among US SMM. METHODS: SMM living with HIV (n = 106) and HIV-negative/status-unknown SMM (n = 351) participated in an online survey (2019-2020). Participants were randomly assigned to 1 of 3 messaging conditions, which varied by level of HIV sexual transmission risk associated with an undetectable viral load (No Risk [U=U]/Low Risk/Control). Participants reported reactions, message accuracy, and reasons for perceiving inaccuracy. We coded open-response data (reactions and reasons) into conceptual categories (eg, "Enthusiasm"). We compared reactions, accuracy ratings, and reasons by condition and serostatus. RESULTS: In the No Risk Condition, common reactions were Enthusiasm (40.0%), Skepticism/Disagreement (20.0%), and Agreement (19.4%), reactions common to comparison conditions. A higher percentage of HIV-negative/status-unknown participants (24.1%) expressed Skepticism/Disagreement in the No Risk Condition compared with other conditions (3.2%-9.7%). Participants living with HIV were more likely than HIV-negative/status-unknown participants to perceive the message as accurate in all conditions. In the No Risk Condition, common reasons for perceiving inaccuracy were Risk Misstated (46.1%), Oversimplified/Caveats Needed (17.1%), and Personal Unfamiliarity/Uncertainty (14.5%), reasons common to comparison conditions. Across conditions, 10.3% of participants attributed message inaccuracy to undetectable being misdefined. CONCLUSION: Most SMM reacted favorably to U=U messaging. However, many-especially HIV-negative/status-unknown SMM-expressed skepticism. Interventions are needed to enhance U=U understanding and acceptance.

A reappraisal of the deep uterine vein: a multimodal exploration with implications for pelvic surgery.

PURPOSE: Pelvic gynecological surgeries, whether for malignant or benign conditions, frequently result in functional complications due to injuries to the autonomic nervous system. Recognizing the deep uterine vein (DUV) as an essential anatomical reference can aid in preserving these structures. Despite its significance, the DUV is infrequently studied and lacks comprehensive documentation in Terminologia Anatomica. This research endeavors to elucidate a detailed characterization of the DUV. METHODS: We undertook a systematic literature review aligning with the "PRISMA" guidelines, sourcing from PUBMED and EMBASE. Our comprehensive anatomical examination encompassed cadaveric dissections and radio-anatomical evaluations utilizing the Anatomage® Table. RESULTS: The literary exploration revealed a consensus on the DUV's description based on both anatomical and surgical observations. It arises from the merger of cervical, vesical, and vaginal veins, coursing through the paracervix in a descending and rearward direction before culminating in the internal iliac vein. The hands-on anatomical study further delineated the DUV's associations throughout its course, highlighting its role in bifurcating the uterus's lateral aspect into two distinct zones: a superior vascular zone housing the uterine artery and ureter and an inferior nervous segment below the DUV representing the autonomic nerve pathway. CONCLUSION: A profound understanding of the subperitoneal space anatomy is paramount for pelvic surgeons to mitigate postoperative complications. The DUV's intricate neurovascular interplays underscore its significance as an indispensable surgical guide for safeguarding nerves and the ureter.

The Implications of PrEP Use, Condom Use, and Partner Viral Load Status for Openness to Serodifferent Partnering Among US Sexual Minority Men (SMM).

PrEP has been reported to facilitate openness to serodifferent sexual partnerships among sexual minority men (SMM). However, other aspects of a sexual scenario likely come into play, including whether or not condoms are used and whether or not the partner living with HIV has an undetectable viral load. This online survey study evaluated the association between PrEP status and openness to serodifferent partnering, as well as the effects of various sexual scenario variables (condom use and partner's viral load) among 268 HIV-negative SMM in the US. Each participant reported their PrEP status and rated their openness to serodifferent partnering in four sexual scenarios, which varied by condom use (with/without) and partner viral load status (detectable/undetectable). Analyses of covariance (ANCOVAs) were conducted to assess differences in openness to serodifferent partnering by PrEP status in each scenario, adjusting for background characteristics. A two-way repeated measures ANCOVA and a three-way mixed factorial ANCOVA, including PrEP status as a between-subjects variable, were also performed to assess the effects of condom use and partner viral load status on openness. Across all scenarios, current PrEP users expressed significantly greater openness to serodifferent partnering compared to participants who had never used PrEP. Current PrEP users were also more likely than former PrEP users to consider partnering with someone with an undetectable viral load without using condoms. Both PrEP users and PrEP-inexperienced individuals had greater openness to serodifferent partnering with a partner having an undetectable (vs. detectable) viral load, which was magnified by condom use among the latter.

RESUMEN: Se ha reportado que hombres de minorías sexuales (HMS) están más dispuestos a tener parejas sexuales serodiferentes cuando usan PrEP. Sin embargo, es probable que existan otros aspectos del contexto sexual, como el uso o no de condones y si la pareja que vive con el VIH tiene o no una carga viral indetectable. Este estudio utilizó una encuesta virtual para evaluar la asociación entre el uso de PrEP y el estar abierto a parejas serodiferentes, así como los efectos de diversas variables del contexto sexual (uso de condón y carga viral de la pareja) entre 268 SMM VIH negativos en los EE. UU. Cada participante reportó su uso de PrEP y estimó su apertura a parejas serodiferentes en cuatro contextos sexuales, que variaron según el uso de condón (con o sin) y el estado de carga viral de la pareja (detectable/indetectable). Para examinar si la apertura a tener parejas sexuales serodiferentes estaba asociada con el uso de PrEP en cada contexto sexual, se realizaron análisis de covarianza (ANCOVA), controlando por características demográficas. También se utilizó ANCOVA de medidas repetidas de dos vías y una ANCOVA de diseño factorial mixto de tres vías, incluyendo el estado de PrEP como una variable entre sujetos, para evaluar los efectos del uso de condón y el estado de carga viral de la pareja en la apertura a tener parejas sexuales serodiferentes. En todos los contextos, las personas usando PrEP en ese momento expresaron una apertura significativamente mayor a las parejas serodiferentes comparados con los participantes que nunca habían usado PrEP. Las personas usando PrEP en ese momento también eran más propensas a considerar asociarse con alguien con una carga viral indetectable sin usar condones que los que habían descontinuado PrEP. Tanto los usuarios de PrEP como las personas sin experiencia en PrEP tuvieron una mayor apertura a tener relaciones serodiferentes con una pareja que tuviera una carga viral indetectable (versus detectable), que se magnificó por el uso de condones entre los sin inexperiencia.

The Potential Role of Undetectable = Untransmittable (U = U) in Reducing HIV Stigma among Sexual Minority Men in the US.

The Undetectable = Untransmittable (U = U) message and its scientific underpinnings have been widely suggested to reduce HIV stigma. However, misunderstanding and skepticism about U = U may prevent this destigmatizing potential from being fully realized. This cross-sectional study examined associations between U = U belief (belief that someone with a sustained undetectable viral load has zero risk of sexually transmitting HIV) and HIV stigma among US sexual minority men. Differences by serostatus and effects of brief informational messaging were also explored. The survey was completed online by 106 men living with HIV and 351 HIV-negative/status-unknown men (2019-2020). Participants were 18-83 years old (M[SD] = 41[13.0]). Most were non-Hispanic White (70.0%) and gay (82.9%). Although nearly all participants (95.6%) were aware of U = U, only 41.1% believed U = U. A greater percentage of participants living with HIV (66.0%) believed U = U compared with HIV-negative/status-unknown participants (33.6%). Among participants living with HIV, U = U belief was not significantly associated with perceived, internalized, or experienced HIV stigma or with viral load prejudice (prejudice against people who have a detectable HIV viral load). Among HIV-negative/status-unknown participants, U = U belief was associated with less frequently enacted HIV discrimination, more positive feelings toward people with an undetectable viral load, and lower personal endorsement of stigmatizing beliefs. Brief informational messaging about U = U did not affect most stigma dimensions and did not favorably affect any. Interventions are needed to correct commonly held, outdated misconceptions about HIV transmission risk. Such initiatives must not only engage people living with HIV but also engage HIV-negative/status-unknown people to maximize the destigmatizing potential of U = U.

RESUMEN: Para reducir el estigma del VIH se ha recomendado difundir extensivamente el mensaje Indetectable = Intransmisible (U = U) y sus fundamentos científicos. Sin embargo, falta de comprensión y escepticismo acerca de U = U pueden impedir que se realice plenamente su potencial desestigmatizante. Este estudio transversal examinó las asociaciones entre la creencia U = U (creencia de que alguien con una carga viral indetectable sostenida tiene cero riesgo de transmitir sexualmente el VIH) y el estigma del VIH entre hombres de minorías sexuales estadounidenses. También se exploró si el efecto de los mensajes informativos breves dependía del estatus serológico. La encuesta fue completada en línea por 106 hombres que viven con el VIH y 351 hombres VIH negativos o de estatus desconocido (2019­2020). Los participantes tenían entre 18 y 83 años (M[DS] = 41[13,0]). La mayoría eran blancos no hispanos (70,0%) y gay (82,9%). Aunque casi todos los participantes (95,6%) sabían sobre U = U, sólo el 41,1% creían en U = U. Un mayor porcentaje de participantes con VIH (66,0%) creían que U = U en comparación con los participantes VIH negativos o de estatus desconocido (33,6%). Entre los participantes con VIH, la creencia U = U no se asoció significativamente con el estigma del VIH percibido, interiorizado o experimentado ni con el prejuicio sobre la carga viral (prejuicio contra las personas que tienen una carga viral de VIH detectable). Entre los participantes VIH negativos/con estatus desconocido, la creencia U = U se asoció con menor frecuencia de discriminación por VIH, sentimientos más positivos hacia las personas con una carga viral indetectable y menor respaldo personal a las creencias estigmatizantes. Los mensajes informativos breves sobre U = U no afectaron la mayoría de las dimensiones del estigma y no afectó favorablemente a ninguno. Se necesitan intervenciones para corregir conceptos frecuentes sobre el riesgo de transmisión del VIH que son erróneos y obsoletos. Para maximizar el potencial desestigmatizador de U = U, estas iniciativas no sólo deben involucrar a las personas que viven con el VIH, sino también a las personas VIH-negativas o de estatus desconocido.

A systematic review of annotation for surgical process model analysis in minimally invasive surgery based on video.

BACKGROUND: Annotated data are foundational to applications of supervised machine learning. However, there seems to be a lack of common language used in the field of surgical data science. The aim of this study is to review the process of annotation and semantics used in the creation of SPM for minimally invasive surgery videos. METHODS: For this systematic review, we reviewed articles indexed in the MEDLINE database from January 2000 until March 2022. We selected articles using surgical video annotations to describe a surgical process model in the field of minimally invasive surgery. We excluded studies focusing on instrument detection or recognition of anatomical areas only. The risk of bias was evaluated with the Newcastle Ottawa Quality assessment tool. Data from the studies were visually presented in table using the SPIDER tool. RESULTS: Of the 2806 articles identified, 34 were selected for review. Twenty-two were in the field of digestive surgery, six in ophthalmologic surgery only, one in neurosurgery, three in gynecologic surgery, and two in mixed fields. Thirty-one studies (88.2%) were dedicated to phase, step, or action recognition and mainly relied on a very simple formalization (29, 85.2%). Clinical information in the datasets was lacking for studies using available public datasets. The process of annotation for surgical process model was lacking and poorly described, and description of the surgical procedures was highly variable between studies. CONCLUSION: Surgical video annotation lacks a rigorous and reproducible framework. This leads to difficulties in sharing videos between institutions and hospitals because of the different languages used. There is a need to develop and use common ontology to improve libraries of annotated surgical videos.

Detection and Diagnosis of Retinoblastoma: Can Mobile Devices Be the Next Step Toward Early Intervention?

Retinoblastoma (RB) is a common intraocular cancer in pediatric patients worldwide, and screening is routinely performed throughout the first few years of life. The diagnosis is often made clinically; however, the diagnosis can be delayed due to undetectable leukocoria because of small tumor size at the time of examination, missed appointments, non-compliance with eye examinations, or failure to perform the exam. As mobile devices continue to gain in both popularity and functionality, their use via applications and smartphone attachments for ocular examination introduces a new avenue for screening, detection, and staging of RB both inside and outside the clinical setting. Currently, research regarding mobile device use is still in its infancy, and further research is required to determine whether mobile devices could play a significant role in assisting with the diagnosis of RB. The purpose of this systematic review was to determine whether the existing literature supports the use of mobile devices by healthcare providers, specifically ophthalmologists and non-ophthalmologists, as well as by parents for the early detection of RB. A comprehensive literature search was conducted via PubMed, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science with a total of 10 studies included in the final analysis.

Ocular Manifestations in Patients with Sensorineural Hearing Loss.

Identification of ocular manifestations in patients with sensorineural hearing loss (SNHL) can have a large impact on the outcome and treatment of pediatric patients. Due to the common co-incidence of ocular manifestations and SNHL in children, both ophthalmologic and hearing loss screening and routine examinations must be conducted to minimize adverse outcomes and worsening of pathology. Early evaluation and diagnosis is imperative for intervention and further development of the patient. Co-incidence requires a thorough evaluation that includes a comprehensive history, examination, and diagnostic testing. In this article, a literature review was conducted to analyze the presentations of various diseases and syndromes, such as Alport Syndrome, Waardenburg Syndrome, Norrie Disease, Usher Disease, Stickler Syndrome, Marfan Syndrome, Congenital Rubella, and Hereditary Optic Neuropathies. We divided the various ocular pathologies into anterior and posterior segment presentations and associated systemic findings for better understanding. Additionally, this review aims to include an update on the management of patients with both ocular and hearing loss manifestations.
