The PROMIS Upper Extremity Computer Adaptive Test Correlates With Previously Validated Metrics in Patients With Carpal Tunnel Syndrome

Background: The Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS UE) computer adaptive test was developed to improve precision and reduce question burden. We hypothesized that in patients with carpal tunnel syndrome (CTS): (1) PROMIS UE would correlate with established patient-reported outcome measures (PROs); (2) the time and number of questions required would be lower than current metrics; (3) there would be no floor or ceiling effects; and (4) PROMIS UE would not correlate with disease severity. Methods: Patients undergoing electrodiagnostic evaluation found to have a primary diagnosis of unilateral CTS prospectively completed PROMIS UE, Quick Disabilities of the Arm, Shoulder and Hand (qDASH), and Boston Carpal Tunnel Syndrome Questionnaire (BCTQ). Electrophysiologic and clinical severity was recorded. The relationships among PROs were described with Spearman coefficients. A floor or ceiling effect was confirmed if >15% of patients achieved the lowest or highest possible score, respectively. Results: Fifty-one patients (average, 53.9 years) were enrolled. An excellent correlation was identified between PROMIS UE and qDASH (R = −0.76, P < .001). There was a good correlation between PROMIS UE and BCTQ (R = −0.58, P < 0.001). The PROMIS UE required less time and fewer questions than qDASH and BCTQ (P = .02 and P < .001). There were no floor or ceiling effects. Neither neurophysiologic nor clinical severity correlated with PROMIS UE (R = 0.24, P > .05 and R = −0.18, P > .05). Conclusions: The PROMIS UE has an excellent correlation with qDASH and a good correlation with BCTQ in patients with CTS. Furthermore, PROMIS UE required less time and fewer questions than established PROs. Used as a single PRO, PROMIS UE represents a practical alternative to current metrics in patients with CTS.     

Exon identity influences splicing induced by exonic variants and in silico prediction efficacy

BackgroundMinigenes and in silico prediction tools are commonly used to assess the impact on splicing of CFTR variants. Exon skipping is often neglected though it could impact the efficacy of targeted therapies. The aim of the study was to identify exon skipping associated with CFTR variants and to evaluate in silico predictions of seven freely available software.MethodsCFTR basal exon skipping was evaluated on endogenous mRNA extracted from non-CF nasal cells and on two CFTR minigene banks. In silico tools and minigene systems were used to evaluate the impact of CFTR exonic variants on exon skipping.ResultsData showed that out of 65 CFTR variants tested, 26 enhanced exon skipping and that in silico prediction efficacy was of 50%-66%. Some in silico tools presented predictions with a bias towards the occurrence of splicing events while others presented a bias towards the absence of splicing events (non-detection including true negatives and false negatives). Classification of exons depending on their basal exon skipping level increased prediction rates up to 80%.ConclusionThis study indicates that taking basal exon skipping into account could orientate the choice of the in silico tools to improve prediction rates. It also highlights the need to validate effects using in vitro assays or mRNA studies in patients. Eventually, it shows that variant-guided therapy should also target exon skipping associated with variants.     

PROMISE: Working with the CF community to understand emerging clinical and research needs for those treated with highly effective CFTR modulator therapy

Highly effective CFTR modulator drug therapy is increasingly available to those with cystic fibrosis. Multiple observational research studies are now being conducted to better understand the impacts of this important therapeutic milestone on long-term outcomes, patient care needs, and future research priorities. PROMISE is a large, multi-disciplinary academic study focused on the broad impacts of starting elexacaftor/tezacaftor/ivacaftor in the US population age 6 years and older. The many areas of investigation and rationale for each are discussed by organ systems, along with recognition of remaining important questions that will not be addressed by this study alone. Knowledge gained through this and multiple complementary studies around the world will help to understand important health outcomes, clinical care priorities, and research needs for a large majority of people treated with these or similarly effective medications targeting the primary cellular impairment in cystic fibrosis.     

Sex-Positivity,Medical Mistrust,and PrEP Conspiracy Beliefs Among HIV-Negative Cisgender Black Sexual Minority Men in Atlanta,Georgia

Because the public health response to the disproportionate HIV burden faced by Black sexual minority men (BSMMM) has focused on sexual risk reduction and disease prevention, other vital components of sexual health (e.g., intimacy, pleasure, benefits of sex) have been often overlooked. Sex-positive describes a more open, holistic approach toward sex and sexuality that prioritizes these other components, though such an approach is rarely applied to BSMM's sexual health. For sex-positive BSMM, risk/preventive discourse may foster or exacerbate medical mistrust as a reaction to the dissonance between how these men view sexual health and how the medical establishment views it, which may discourage sexual healthcare-seeking. We assessed sex-positivity and its association with medical mistrust and PrEP conspiracy beliefs among 206 HIV-negative cisgender BSMM in Atlanta, Georgia. We performed exploratory factor analytic procedures on responses to a sex-positivity scale, followed by multivariable linear regressions to determine sex-positivity’s associations with medical mistrust and PrEP conspiracy beliefs. We extracted two sex-positivity factors: sexual freedom (α?=?0.90), reflecting openness toward casual sex and rejection of sexual mores, and essence of sex (α?=?0.77), reflecting the intimate, relational, and pleasurable qualities of sex. Sexual freedom was independently associated with perceived provider deception (β?=?0.19, CI?=?0.04, 0.34). Essence of sex was independently associated with PrEP conspiracy beliefs (β?=?0.16, CI?=?0.02, 0.31) and marginally associated with perceived provider deception (β?=?0.14, CI?=???0.00, 0.29). Healthcare providers and public health practitioners may cultivate greater trust with BSMM by incorporating a sex-positive approach into patient/participant interactions, clinical decision-making, and interventions. Improving access to sexual pleasure acknowledges BSMM’s right to optimal, holistic sexual health.

     

Perceptions of Sexual Images: Factors Influencing Responses to the Ubiquitous External Ejaculation

The debate over pornography has drawn attention to sex differences not only in the frequency of pornography consumption but also in the different ways males and females may perceive sexually explicit images and respond to them. Some of these differences may be due to sex differences in a variety of factors including sexual strategies and disgust, in particular, disgust related to pathogen avoidance. There is a large literature that focuses on how pathogen avoidance has shaped human behavior from political ideology to in-group/outgroup behavior to sexual risk taking/avoidance. This study examined sex differences in perceptions and how they are influenced by the emotional context of the image as well as individual difference factors, including disgust sensitivity, mate value, sociosexuality, and sexual orientation. Participants viewed a series of sexually explicit images of external ejaculations and rated them in terms of being positive, neutral, or negative. The factors accounting for the greatest variance in perceptions were target affect and sex, sexual orientation, and respondent sex, followed by pathogen and sexual disgust, self-perceived mate value, and sociosexual attitudes and desire.

     

Acceptability and Feasibility of Geographically Explicit Ecological Momentary Assessment Among Men Who Have Sex with Men

Syphilis among men who have sex with men (MSM) has increased greatly in the past twenty years in the U.S. Geographically explicit ecological momentary assessment (GEMA), in which behaviors are geotagged and contextualized in time and space, may contribute to a greater understanding of transmission risk. The objective was to determine the acceptability and feasibility of GEMA for assessing HIV and syphilis transmission risk behaviors among a sample of MSM. Participants responded to a brief survey five times a day for two weeks. Feasibility was measured by participant recruitment, enrollment, prompts received and answered, geotagged prompts, and technical interference with data collection. Acceptability was measured by ratings of enjoyment and willingness for future participation. Summaries of five behavioral measures from the brief survey were calculated. Among the 83 participants contacted, 67.5% (56) expressed interest, 98% (55) were scheduled, and 81.8% (45) were enrolled. Participants answered 78.3% (2,277) of prompts received and 87.7% (1,998) of answered prompts were geotagged. Overall, 70.5% (31) enjoyed participating and 91.1% (41) were willing to participate in the future. Among prompts answered, missingness was low for five behavioral measures (range 0.2% (4) to 0.7% (16)). Feasibility and acceptability were high and missingness was low on behavioral measures in this MSM study population. Most participants reported that they would participate again. Future work should focus on whether GEMA improves our understanding of syphilis and HIV transmission risk.

Localized Bullous Pemphigoid Following Orthopedic Surgery

Bullous pemphigoid is an autoimmune condition whereby the immune system forms antibodies that target the skin, resulting in the formation of blisters in a generalized and symmetric pattern. Localized bullous pemphigoid can occur in special circumstances. Here, we describe two patients that developed localized bullous pemphigoid in one lower extremity following orthopedic surgery. We propose that underlying edema following orthopedic surgery is a potential trigger for localized bullous pemphigoid.
