Item Acute pancreatitis precedes chronic pancreatitis in the majority of patients: Results from the NAPS2 consortium(Elsevier, 2022-12) Singh, Vikesh K.; Whitcomb, David C.; Banks, Peter A.; AlKaade, Samer; Anderson, Michelle A.; Amann, Stephen T.; Brand, Randall E.; Conwel, Darwin L.; Cote, Gregory A.; Gardner, Timothy B.; Gelrud, Andres; Guda, Nalini; Forsmark, Christopher E.; Lewis, Michele; Sherman, Stuart; Muniraj, Thiruvengadam; Romagnuolo, Joseph; Tan, Xiaoqing; Tang, Gong; Sandhu, Bimaljit S.; Slivka, Adam; Wilcox, C. Mel; Yadav, Dhiraj; Medicine, School of MedicineIntroduction: The mechanistic definition of chronic pancreatitis (CP) identifies acute pancreatitis (AP) as a precursor stage. We hypothesized that clinical AP frequently precedes the diagnosis of CP and is associated with patient- and disease-related factors. We describe the prevalence, temporal relationship and associations of AP in a well-defined North American cohort. Methods: We evaluated data from 883 patients with CP prospectively enrolled in the North American Pancreatitis Studies across 27 US centers between 2000 and 2014. We determined how often patients had one or more episodes of AP and its occurrence in relationship to the diagnosis of CP. We used multivariable logistic regression to determine associations for prior AP. Results: There were 624/883 (70.7%) patients with prior AP, among whom 161 (25.8%) had AP within 2 years, 115 (18.4%) within 3–5 years, and 348 (55.8%) >5 years prior to CP diagnosis. Among 504 AP patients with available information, 436 (86.5%) had >1 episode. On multivariable analyses, factors associated with increased odds of having prior AP were a younger age at CP diagnosis, white race, abdominal pain, pseudocyst(s) and pancreatic duct dilatation/stricture, while factors associated with a lower odds of having prior AP were exocrine insufficiency and pancreatic atrophy. When compared with patients with 1 episode, those with >1 AP episode were diagnosed with CP an average of 5 years earlier. Conclusions: Nearly three-quarters of patients were diagnosed with AP prior to CP diagnosis. Identifying which AP patients are at-risk for future progression to CP may provide opportunities for primary and secondary prevention.Item Adolescent Substance Use and Occupational Therapy Interventions: A Rapid Systematic Review(2021-05-05) Byrn, Hannah; Davila, Danielle; Green, Samantha; Kendall, Mary; Larson, Sydney; Prentice, Alexandra; Chase, Anthony; Petrenchik, Terry; Department of Occupational Therapy, School of Health and Human SciencesThis rapid systematic review analyzes the evidence for substance use reduction through therapeutic interventions and activities in adolescents between the ages of 13-25, along with the potential for implementation in the field of occupational therapy. Adolescents with substance use disorders (SUDs) often have specific challenges regarding their family interactions, cultural beliefs, school engagement, and community support. It can be difficult for adolescents with SUDs to successfully navigate their ever changing lives, as they may also present with comorbid psychiatric conditions. It is noted that throughout this review, many interventions were the first of their kind and focused on targeting adolescents within the contexts of their environment. Many studies utilized specific techniques aimed at improving adolescents’ intrinsic beliefs regarding their substance use. Overall, low to moderate evidence was found for the effectiveness of various interventions to reduce adolescent substance use. More exhaustive research is needed to evaluate the usefulness of these interventions, as many were done in very specific settings with very individualized populations. Moreover, occupational therapists should be cautious before implementation into practice, as none of the studies evaluated explicitly examined the role of occupational therapy. More investigation is required to determine how these interventions can be applied to the field of occupational therapy.Item Alzheimer’s disease research progress in the Mediterranean region: the Alzheimer’s Association International Conference Satellite Symposium(Wiley, 2022) Sexton, Claire; Solis, Michele; Aharon-Peretz, Judith; Alexopoulos, Panagiotis; Apostolova, Liana; Bayen, Eléonore; Birkenhager, Betty; Cappa, Stefano; Constantinidou, Fofi; Fortea, Juan; Gerritsen, Debby L.; Hassanin, Hany I.; Ibanez, Agustin; Ioannidis, Panagiotis; Karageorgiou, Elissaios; Korczyn, Amos; Leroi, Iracema; Lichtwarck, Bjorn; Logroscino, Giancarlo; Lynch, Chris; Mecocci, Patrizia; Molinuevo, Jose Luis; Papatriantafyllou, John; Papegeorgiou, Sokratis; Politis, Antonis; Raman, Rema; Ritchie, Karen; Sanchez-Juan, Pascual; Sano, Mary; Scarmeas, Nikolas; Spiru, Luiza; Stathi, Afroditi; Tsolaki, Magda; Yener, Görsev; Zaganas, Ioannis; Zygouris, Stelios; Carrillo, Maria; Neurology, School of MedicineAs research and services in the Mediterranean region continue to increase, so do opportunities for global collaboration. To support such collaborations, the Alzheimer's Association was due to hold its seventh Alzheimer's Association International Conference Satellite Symposium in Athens, Greece in 2021. Due to the COVID-19 pandemic, the meeting was held virtually, which enabled attendees from around the world to hear about research efforts in Greece and the surrounding Mediterranean countries. Research updates spanned understanding the biology of, treatments for, and care of people with Alzheimer's disease (AD_ and other dementias. Researchers in the Mediterranean region have outlined the local epidemiology of AD and dementia, and have identified regional populations that may expedite genetic studies. Development of biomarkers is expected to aid early and accurate diagnosis. Numerous efforts have been made to develop culturally specific interventions to both reduce risk of dementia, and to improve quality of life for people living with dementia.Item Amyloid and Tau Pathology Associations With Personality Traits, Neuropsychiatric Symptoms, and Cognitive Lifestyle in the Preclinical Phases of Sporadic and Autosomal Dominant Alzheimer’s Disease(Elsevier, 2021) Pichet Binette, Alexa; Vachon-Presseau, Étienne; Morris, John; Bateman, Randall; Benzinger, Tammie; Collins, D. Louis; Poirier, Judes; Breitner, John C. S.; Villeneuve, Sylvia; Dominantly Inherited Alzheimer Network (DIAN); PREVENT-AD Research Group; Psychiatry, School of MedicineBackground: Major prevention trials for Alzheimer's disease (AD) are now focusing on multidomain lifestyle interventions. However, the exact combination of behavioral factors related to AD pathology remains unclear. In 2 cohorts of cognitively unimpaired individuals at risk of AD, we examined which combinations of personality traits, neuropsychiatric symptoms, and cognitive lifestyle (years of education or lifetime cognitive activity) related to the pathological hallmarks of AD, amyloid-β, and tau deposits. Methods: A total of 115 older adults with a parental or multiple-sibling family history of sporadic AD (PREVENT-AD [PRe-symptomatic EValuation of Experimental or Novel Treatments for AD] cohort) underwent amyloid and tau positron emission tomography and answered several questionnaires related to behavioral attributes. Separately, we studied 117 mutation carriers from the DIAN (Dominant Inherited Alzheimer Network) study group cohort with amyloid positron emission tomography and behavioral data. Using partial least squares analysis, we identified latent variables relating amyloid or tau pathology with combinations of personality traits, neuropsychiatric symptoms, and cognitive lifestyle. Results: In PREVENT-AD, lower neuroticism, neuropsychiatric burden, and higher education were associated with less amyloid deposition (p = .014). Lower neuroticism and neuropsychiatric features, along with higher measures of openness and extraversion, were related to less tau deposition (p = .006). In DIAN, lower neuropsychiatric burden and higher education were also associated with less amyloid (p = .005). The combination of these factors accounted for up to 14% of AD pathology. Conclusions: In the preclinical phase of both sporadic and autosomal dominant AD, multiple behavioral features were associated with AD pathology. These results may suggest potential pathways by which multidomain interventions might help delay AD onset or progression.Item “An Extra Variable to Consider”—Vaccine-Induced Seropositivity and Adolescent HIV Vaccine Clinical Trials(Oxford University Press, 2022) Fatola, Omolayo; Corneli, Amy; Perry, Brian; Hanlen-Rosado, Emily; Nsonwu, Adora; Constantine, Evangelia P.; Thompson, Amelia B.; Medicine, School of MedicineOur study explores the understanding of vaccine-induced seropositivity (VISP) and its potential impact on US adolescents' and caregivers' willingness to participate in adolescent HIV vaccine clinical trials. Findings from in-depth interviews suggest that addressing concerns about VISP will be essential for future pediatric HIV vaccine trials in the United States.Item Association Between Subjective Cognitive Decline and Twice-Weekly Muscle-Strengthening Activities in Middle-Aged and Older US Adults: An Analysis of the 2019 Behavioral Risk Factor Surveillance System(Sage, 2024) Schroeder, Matthew W.; Waring, Molly E.; Fowler, Nicole R.; Mace, Ryan A.; Pagoto, Sherry L.; Medicine, School of MedicinePurpose: Adults with subjective cognitive decline (SCD), the self-reported concern of reduced cognitive function, are recommended to do physical activity for its brain health benefits. US adults aged ≥45 with SCD are less likely to meet the American College of Sports Medicine (ACSM) aerobic activity recommendations. Their engagement in muscle-strengthening activities is unknown. We aimed to identify if US adults aged ≥45 with SCD are less likely to do twice-weekly muscle-strengthening activities compared to those without SCD. Design: Secondary analysis of the 2019 Behavioral Risk Factor Surveillance System (BRFSS) data. Sample: 114 164 respondents, representing approximately 59 million US adults aged ≥45. Measures: SCD was indicated if the respondent reported confusion or memory loss during the past 12 months (yes/no). Respondents reported the frequency of muscle-strengthening activities, which we categorized as meeting the ACSM's recommendations (2+ times per week) or not (<2 times per week). Analysis: Crude and adjusted logistic regression models controlling for variables associated with SCD and muscle-strengthening activities. The models used sample weights to represent US adults in the included 31 states and Washington D.C. Results: US adults aged ≥45 with SCD were less likely to do twice-weekly muscle-strengthening activities than those without SCD (28.6% [SE: .8%] vs 33.5% [SE: .3%], adjusted OR, .9; 95% CI: .9-1.0). Conclusion: Primary care providers should encourage middle-aged and older patients to engage in muscle-strengthening and aerobic activities.Item Associations between the stanford integrated psychosocial assessment for transplant and one-year lung transplant medical and psychosocial outcomes(Springer Nature, 2023-06-12) Hinton-Froese, Kendra E.; Teh, Lisa; Henderson, Danielle R.; Hage, Chadi A.; Chernyak, Yelena; Psychiatry, School of MedicineThe Stanford Integrated Psychosocial Assessment for Transplant (SIPAT) is a standardized measure of the psychosocial risk profile of solid organ transplant candidates. While studies have found associations between this measure and transplant outcomes, to date this has not been examined in lung transplant recipients. We examined relations between pre-transplant SIPAT scores and 1-year lung transplant medical and psychosocial outcomes in a sample of 45 lung transplant recipients. The SIPAT was significantly associated with 6-minute walk test (χ2(1) = 6.47, p = .010), number of readmissions (χ2(1) = 6.47, p = .011), and mental health services utilization (χ2(1) = 18.15, p < .001). It was not a significantly associated with the presence of organ rejection or mortality (ps > 0.10). Results suggest that the SIPAT can help identify patients who are at an elevated risk for transplant complications and thus would benefit from services to mitigate risk factors and improve outcomes.Item Attitudes towards microbicide use for bacterial vaginosis in pregnancy(CSIRO, 2014-09) Catallozzi, Marina; Williams, Camille Y.; Zimet, Gregory D.; Hargreaves, Katharine M.; Gelber, Shari E.; Ratner, Adam J.; Stanberry, Lawrence R.; Rosenthal, Susan L.; Department of Pediatrics, IU School of MedicineBackground Bacterial vaginosis (BV) is the most common reproductive tract infection (RTI) and is a significant risk factor for preterm birth. Microbicides could be an option for the prevention and treatment of BV in pregnancy, and understanding use of the product will be crucial. The present study explored attitudes of women in the third trimester of pregnancy regarding topical microbicide use for the prevention and treatment of BV. METHODS: Twenty-six women in their third trimester were interviewed regarding their knowledge and beliefs about RTIs during pregnancy and attitudes concerning the use of topical microbicides for prevention and treatment of BV. RESULTS: Participants had a mean age of 24.9 years, were largely under-represented minorities and the majority had had past pregnancies. Participants had knowledge and experience with RTIs but not BV. They were open to the use of microbicides for prevention or treatment of BV, but believed that women requiring treatment would be more motivated. Rationales for acceptability were most commonly related to the baby's health. Practical issues that may interfere with use were often, but not always, related to pregnancy. There was a range of attitudes about partner involvement in decision-making and the practicalities of product use. CONCLUSION: Pregnant women are knowledgeable about RTIs but not necessarily BV. The women in this study found microbicide use acceptable, particularly for treatment. To improve acceptability and use, education would be needed about BV and possible complications, how to overcome practical problems and the value of involving partners in the decision.Item Barriers to Screening: An Analysis of Factors Impacting Screening for Type 1 Diabetes Prevention Trials(Oxford University Press, 2023-01-11) Kinney, Mara; You, Lu; Sims, Emily K.; Wherrett, Diane; Schatz, Desmond; Lord, Sandra; Krischer, Jeffrey; Russell, William E.; Gottlieb, Peter A.; Libman, Ingrid; Buckner, Jane; DiMeglio, Linda A.; Herold, Kevan C.; Steck, Andrea K.; Pediatrics, School of MedicineContext: Participants with stage 1 or 2 type 1 diabetes (T1D) qualify for prevention trials, but factors involved in screening for such trials are largely unknown. Objective: To identify factors associated with screening for T1D prevention trials. Methods: This study included TrialNet Pathway to Prevention participants who were eligible for a prevention trial: oral insulin (TN-07, TN-20), teplizumab (TN-10), abatacept (TN-18), and oral hydroxychloroquine (TN-22). Univariate and multivariate logistic regression models were used to examine participant, site, and study factors at the time of prevention trial accrual. Results: Screening rates for trials were: 50% for TN-07 (584 screened/1172 eligible), 9% for TN-10 (106/1249), 24% for TN-18 (313/1285), 17% for TN-20 (113/667), and 28% for TN-22 (371/1336). Younger age and male sex were associated with higher screening rates for prevention trials overall and for oral therapies. Participants with an offspring with T1D showed lower rates of screening for all trials and oral drug trials compared with participants with other first-degree relatives as probands. Site factors, including larger monitoring volume and US site vs international site, were associated with higher prevention trial screening rates. Conclusions: Clear differences exist between participants who screen for prevention trials and those who do not screen and between the research sites involved in prevention trial screening. Participant age, sex, and relationship to proband are significantly associated with prevention trial screening in addition to key site factors. Identifying these factors can facilitate strategic recruitment planning to support rapid and successful enrollment into prevention trials.Item A clinical trial method to show delay of onset in Huntington disease(Wiley, 2019-02) Paulsen, Jane S.; Lourens, Spencer; Kieburtz, Karl; Zhang, Ying; Biostatistics, School of Public HealthBackground: Disease-modifying clinical trials in persons without symptoms are often limited in methods to assess the impact associated with experimental therapeutics. This study suggests sample enrichment approaches to facilitate preventive trials to delay disease onset in individuals with the dominant gene for Huntington disease. Methods: Using published onset prediction indexes, we conducted the receiver operating curve analysis for diagnosis within a 3-year clinical trial time frame. We determined optimal cut points on the indexes for participant recruitment and then conducted sample size and power calculations to detect varying effect sizes for treatment efficacy in reducing 3-year rates of disease onset (or diagnosis). Results: Area under the curve for 3 onset prediction indexes all demonstrated excellent value in sample enrichment methodology, with the best-performing index being the multivariate risk score (MRS). Conclusions: This study showed that conducting an intervention trial in premanifest and prodromal individuals with the gene expansion for Huntington disease is highly feasible using sample enrichment recruitment methods. Ongoing natural history studies are highly likely to indicate additional markers of disease prior to diagnosis. Statistical modeling of identified markers can facilitate participant enrichment to increase the likelihood of detecting a difference between treatment arms in a cost-effective and efficient manner. Such variations may expedite translation of emerging therapies to persons in an earlier phase of the disease.
