RESUMEN

Exposure to discrimination has been linked to lower HIV antiretroviral therapy (ART) adherence and poor HIV care outcomes among Black Americans. Coping has been shown to mitigate the harmful effects of discrimination on health behaviors, but the use of cultural relevant Africultural coping strategies is understudied as a moderator of the association between intersectional discrimination and ART adherence among Black Americans. We used adjusted logistic regression to test whether Africultural coping strategies (cognitive/emotional debriefing; collective; spiritual-centered; ritual-centered) moderated associations between multiple forms of discrimination (HIV, sexual orientation, race) and good ART adherence (minimum of 75% or 85% of prescribed doses taken, as measured by electronic monitoring in separate analyses) among 92 sexual minority Black Americans living with HIV. Mean adherence was 66.5% in month 8 after baseline (36% ≥ 85% adherence; 49% ≥ 75% adherence). Ritual-centered coping moderated the relationship between each of the three types of discrimination at baseline and good ART adherence in month 8 (regardless of the minimum threshold for good adherence); when use of ritual coping was low, the association between discrimination and adherence was statistically significant. The other three coping scales each moderated the association between racial discrimination and good ART adherence (defined by the 75% threshold); cognitive/emotional debriefing was also a moderator for both HIV- and race-related discrimination at the 85% adherence threshold. These findings support the benefits of Africultural coping, particularly ritual-centered coping, to help sexual minority Black Americans manage stressors associated with discrimination and to adhere well to ART.

RESUMEN

Loneliness, an emerging public health problem, is higher among people living with HIV and is associated with negative health outcomes. Black/African Americans have a high burden of HIV, and little is known about the characteristics of loneliness among Black adults living with HIV; therefore, this study sought to understand the sociodemographic and psychosocial correlates of Black adults living with HIV who are lonely and the implications of loneliness for their health outcomes. A sample of 304 Black adults living with HIV (73.8% sexual minority men) in Los Angeles County, CA, USA, completed the survey items assessing sociodemographic and psychosocial characteristics, social determinants of health, health outcomes, and loneliness. Antiretroviral therapy (ART) adherence was assessed electronically with the medication event monitoring system. Bivariate linear regressions analysis showed higher loneliness scores among those with higher levels of internalized HIV stigma, depression, unmet needs, and discrimination related to HIV serostatus, race, and sexual orientation. In addition, participants who were married or living with a partner, had stable housing, and reported receiving more social support had lower levels of loneliness. In multivariable regression models controlling for correlates of loneliness, loneliness was found to be a significant independent predictor of worse general physical health, worse general mental health, and greater depression. Loneliness was marginally associated with lower ART adherence. Findings suggest that Black adults living with HIV, who experience multiple intersectional stigmas, require targeted interventions and resources.

RESUMEN

Enhanced S-cone syndrome (ESCS), also known as Goldmann-Favre syndrome, is a retinal degeneration that presents in childhood and leads to progressive nyctalopia and visual field loss. In advanced cases, this degeneration can result in loss of central visual acuity. We describe the case of a 15-year-old boy with ESCS who presented with retinal detachment, a rare complication.

RESUMEN

Sepsis, the leading cause of mortality in hospitals, currently lacks effective early diagnostics. A new cellular host response test, the IntelliSep test, may provide an indicator of the immune dysregulation characterizing sepsis. The objective of this study was to examine the correlation between the measurements performed using this test and biological markers and processes associated with sepsis. Phorbol myristate acetate (PMA), an agonist of neutrophils known to induce neutrophil extracellular trap (NET) formation, was added to whole blood of healthy volunteers at concentrations of 0, 200, and 400 nM and then evaluated using the IntelliSep test. Separately, plasma from a cohort of subjects was segregated into Control and Diseased populations and tested for levels of NET components (citrullinated histone (cit-H3) DNA and neutrophil elastase (NE) DNA) using customized ELISA assays and correlated with ISI scores from the same patient samples. Significant increases in IntelliSep Index (ISI) scores were observed with increasing concentrations of PMA in healthy blood (0 and 200: p < 10-10; 0 and 400: p < 10-10). Linear correlation was observed between the ISI and quantities of NE DNA and Cit-H3 DNA in patient samples. Together these experiments demonstrate that the IntelliSep test is associated with the biological processes of leukocyte activation and NETosis and may indicate changes consistent with sepsis.

RESUMEN

The current study examined the prevalence and typology of unmet needs and the association between unmet needs and HIV antiretroviral therapy (ART) medication adherence among a sample of Black people living with HIV(PLHIV) (N = 304) in Los Angeles, CA. We found a high prevalence of unmet needs, with 32% of participants reporting having two or more unmet needs. The most common unmet needs category was basic benefits needs (35%), followed by subsistence needs (33%), and health needs (27%). Significant correlates of unmet needs included food insecurity, history of homelessness, and history of incarceration. A greater number of unmet needs and any unmet basic benefits needs were each significantly associated with lower odds of HIV ART medication adherence. These findings provide further evidence linking the social determinants of health and social disenfranchisement to ART medication adherence among Black PLHIV.

RESUMEN

The British and Irish Chapter of the International Society for Magnetic Resonance in Medicine (BIC-ISMRM) held a workshop entitled "Steps on the path to clinical translation" in Cardiff, UK, on 7th September 2022. The aim of the workshop was to promote discussion within the MR community about the problems and potential solutions for translating quantitative MR (qMR) imaging and spectroscopic biomarkers into clinical application and drug studies. Invited speakers presented the perspectives of radiologists, radiographers, clinical physicists, vendors, imaging Contract/Clinical Research Organizations (CROs), open science networks, metrologists, imaging networks, and those developing consensus methods. A round-table discussion was held in which workshop participants discussed a range of questions pertinent to clinical translation of qMR imaging and spectroscopic biomarkers. Each group summarized their findings via three main conclusions and three further questions. These questions were used as the basis of an online survey of the broader UK MR community.

RESUMEN

BACKGROUND: Internalizing (anxiety and mood) disorders (INTD) commonly co-occur (are "comorbid") with alcohol use disorder (AUD). The literature suggests that excessive alcohol use aimed at coping with INTD symptoms is, at best, a partial explanation for the high comorbidity rates observed. We hypothesized that individuals with INTD experience greater susceptibility to developing AUD symptoms due to the partially shared neurobiological dysfunctions underlying both conditions. We probe this hypothesis by testing the prediction that, after accounting for the volume of alcohol intake, individuals with INTD experience higher levels of alcohol-related symptoms. METHODS: Data from the National Epidemiological Survey on Alcohol-Related Conditions (NESARC) Wave 3 were used for the primary analyses, and NESARC Wave 1 data were used for independent replication analyses. Individuals who reported any alcohol use in the prior year were categorized as: (1) never having had an INTD diagnosis ("INTD-Never"); (2) having a remitted INTD diagnosis only ("INTD-Remitted"); or (3) having current INTD diagnosis ("INTD-Current"). Between-group contrasts of alcohol-related symptoms controlled for total alcohol intake (past year), drinking pattern (e.g., binging) and variables previously shown to mark exaggerated AUD symptoms relative to drinking amount (e.g., SES, gender, and family history). RESULTS: With all covariates in the model, individuals in the INTD-Current group and the INTD-Remitted group reported significantly greater alcohol-related symptoms than those in the INTD-Never group but did not themselves differ in level of alcohol-related symptoms. These results were replicated in the NESARC 1 dataset. CONCLUSIONS: Individuals with INTD experience more alcohol-related symptoms than those who drink at the same level. While considering other explanations, we argue that this "harm paradox" is best explained by the view that INTD confers a neurobiologically mediated susceptibility to the development of AUD symptoms.

RESUMEN

Structural inequities have led to HIV disparities, including relatively low antiretroviral therapy adherence and viral suppression rates among Black Americans living with HIV. We conducted a randomized controlled trial of Rise, a community-based culturally congruent adherence intervention, from January 2018 to December 2021 with 166 (85 intervention, 81 control) Black adults living with HIV in Los Angeles County, California [M (SD) = 49.0 (12.2) years-old; 76% male]. The intervention included one-on-one counseling sessions using basic Motivational Interviewing style to problem solve about adherence, as well as referrals to address unmet needs for social determinants of health (e.g., housing services, food assistance). Assessments included electronically monitored adherence; HIV viral load; and baseline, 7-month follow-up, and 13-month follow-up surveys of sociodemographic characteristics, HIV stigma, medical mistrust, and HIV-serostatus disclosure. Repeated-measures intention-to-treat regressions indicated that Rise led to significantly (two-fold) higher adherence likelihood, lower HIV stigmatizing beliefs, and reduced HIV-related medical mistrust. Effects on HIV viral suppression, internalized stigma, and disclosure were non-significant. Moreover, Rise was cost-effective based on established standards: The estimated cost per person to reach optimal adherence was $335 per 10% increase in adherence. Interventions like Rise, that are culturally tailored to the needs of Black populations, may be optimal for Black Americans living with HIV (ClinicalTrials.gov #NCT03331978).


RESUMEN: Las desigualdades estructurales han dado lugar a disparidades relacionadas con el VIH, incluyendo la relativamente baja adherencia a la terapia antirretroviral (TAR) y las tasas de supresión viral entre los afroamericanos que viven con el VIH. Conducimos una prueba controlada aleatoria de Rise, una intervención de adherencia culturalmente congruente basada en la comunidad, desde Enero de 2018 hasta Diciembre de 2021 con 166 (85 intervención, 81 controlada) adultos afroamericanos que viven con el VIH en el condado de Los Ángeles, California [M (SD) = 49.0 (12,2) años; 76% de hombres]. La intervención incluyó sesiones de asesoramiento individualizadas, usando el estilo básico Motivacional para las entrevistas, para resolver los problemas de adherencia como también referencias para confrontar sus necesidades insatisfechas de los determinantes sociales de la salud (por ejemplo, servicios de vivienda y asistencia de alimentos). Las evaluaciones incluyeron la adherencia monitoreada electrónicamente; la carga viral del VIH; y encuestas de referencia, seguimiento a los 7 meses y seguimiento a los 13 meses sobre características sociodemográficas, el estigma del VIH, la desconfianza médica y divulgación del estado serológico respecto al VIH. Los efectos sobre la supresión viral del VIH, el estigma interiorizado y la revelación de información no fueron significativos. Además, Rise fue rentable según los estándares establecidos: El costo estimado por persona para alcanzar la adherencia óptima fue de 335 dólares por cada 10% de aumento en la adherencia. Las intervenciones como Rise, que se adaptan culturalmente a las necesidades de las poblaciones afroamericana, podrían ser óptimas para los estadounidenses afroamericanos que viven con el VIH.

RESUMEN

OBJECTIVE: Studies have demonstrated that reduced drinking without total abstinence is associated with improved outcomes in outpatients with alcohol use disorder (AUD). We sought to examine this question in AUD inpatients who have comorbid anxiety disorders, a common presentation in AUD. METHOD: This is a secondary analysis of data from a randomized controlled trial for N = 241 inpatients with AUD and comorbid anxiety disorders. Change from baseline drinking level was measured at 1-, 4-, and 12-months postdischarge, and psychological and functional outcomes were measured at 4- and 12-months postdischarge. Three groups were compared: abstinent, reduced (reduced drinking by 1-3 World Health Organization drinking risk levels without abstinence), or nonreduced (maintained or increased drinking risk level). RESULTS: At 1-, 4-, and 12-months posttreatment, most patients reported abstinence (83, 63, and 60%), and 11, 25, and 26% reported drinking at a reduced level. Drinking reductions achieved at 1-month posttreatment were maintained at 12-month posttreatment by 74% of participants. Overall, the abstinent group reported the best psychological and functional outcomes at follow-ups, followed by the reduced group. Few differences were observed between reducers and nonreducers, but reducers reported significantly better alcohol dependence severity and alcohol-related problems than nonreducers. CONCLUSIONS: Though abstinence was associated with the best outcomes in this abstinence-based treatment sample, we conclude that reduced drinking is also associated with significant improvements in alcohol-related outcomes in inpatients with AUD and comorbid anxiety disorders.At 1-, 4-, and 12-months posttreatment, most patients reported abstinence (83, 63, and 60%), and 11, 25, and 26% reported drinking at a reduced level. Drinking reductions achieved at 1-month posttreatment were maintained at 12-month posttreatment by 74% of participants. Overall, the abstinent group reported the best psychological and functional outcomes at follow-ups, followed by the reduced group. Few differences were observed between reducers and nonreducers, but reducers reported significantly (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMEN

Background: Drinking to cope with negative affect confers a direct risk of alcohol problems independently of greater alcohol consumption (i.e., confers susceptibility to the alcohol harm paradox). However, it remains unclear whether this risk is common across gender and countries. Methods: The current study applied path analysis to two cross-sectional samples of 18-25-year-old undergraduate hazardous drinking students recruited from the UK (Study 1; N = 873) and internationally (Study 2; N = 4064 recruited in Argentina, Canada, South Africa, Spain, Uruguay, USA, and England). The Drinking Motives Questionnaire (DMQ) measured drinking to cope with negative affect and drinking to enhance positive affect (i.e., enhancement motives). The Alcohol Use Disorders Identification Test (AUDIT) measured alcohol consumption and problems. Results: In both studies, drinking to cope with negative affect had a direct effect on alcohol problems (S1: ß = 0.259, SE = 0.031, p <.001; S2: ß = 0.255, SE = 0.017, p <.001), and only a negligible proportion of this effect was mediated by alcohol consumption (S1: 2.58 %, p =.550; S2: 0.79 %, p=.538). By contrast, drinking to enhance positive affect had a smaller direct effect on alcohol problems (S1: ß = 0.000, SE = 0.033, p =.989; S2: ß = 0.044, SE = 0.017, p =.009), and a substantial proportion of this effect was mediated by greater alcohol consumption (S1: 99.76 %, p <.001; S2: 60.36 %, p <.001). Crucially, in both studies, the direct effect of drinking to cope on alcohol problems was invariant across gender and countries. Conclusions: These findings suggest that individuals who endorse drinking to cope with negative affect are uniquely susceptible to the alcohol harm paradox, that is, greater alcohol problems which cannot be explained by greater alcohol consumption, and this susceptibility is common across gender and countries.

RESUMEN

Big trees and abundant species dominate forest structure and composition. As a result, their spatial distribution and interactions with other species and individuals may contribute disproportionately to the emergence of spatial heterogeneity in richness patterns. We tested scale-dependent spatial patterning and species richness structures to understand the role of individual trees (big trees) and species (abundant species) in driving spatial richness patterns on a 25 ha plot in a diverse tropical forest of Australia. The individual species area relationship (ISAR) was used to assess species richness in neighborhoods ranging from 1 to 50 m radii around all big trees (≥70 cm dbh, n = 296) and all species with more than 100 individuals in the plot (n = 53). A crossed ISAR function was also used to compute species richness around big trees for trees of different size classes. Big individuals exert some spatial structuring on other big and mid-sized trees in local neighborhoods (up to 30 m and 16 m respectively), but not on small trees. While most abundant species were neutral with respect to richness patterns, we identified consistent species-specific signatures on spatial patterns of richness for 14 of the 53 species. Seven species consistently had higher than expected species richness in their neighborhood (species "accumulators"), and seven had lower than expected (species "repellers") across all spatial scales. Common traits of accumulators and repeller species suggest that niche partitioning along disturbance gradients is a primary mechanism driving spatial richness patterns, which is then manifested in large-scale spatial heterogeneity in species distributions across the plot.

RESUMEN

BACKGROUND: Ecological momentary assessment (EMA) studies have provided conflicting evidence for the mood regulation tenet that people drink in response to positive and negative moods. The current study examined mood-to-alcohol relationships idiographically to quantify the prevalence and intensity of relationships between positive and negative moods and drinking across individuals. METHOD: We used two EMA samples: 96 heavy drinking college students (sample 1) and 19 young adults completing an ecological momentary intervention (EMI) for drinking to cope (sample 2). Mood and alcohol use were measured multiple times per day for 4-6 weeks. Mood-alcohol relationships were examined using three different analytic approaches: standard multilevel modeling, group causal modeling, and idiographic causal modeling. RESULTS: Both multilevel modeling and group causal modeling showed that participants in both samples drank in response to positive moods only. However, idiographic causal analyses revealed that only 63% and 21% of subjects (in samples 1 and 2, respectively) drank following any positive mood. Many subjects (24% and 58%) did not drink in response to either positive or negative mood in their daily lives, and very few (5% and 16%) drank in response to negative moods throughout the EMA protocol, despite sample 2 being selected specifically because they endorse drinking to cope with negative mood. CONCLUSION: Traditional group-level analyses and corresponding population-wide theories assume relative homogeneity within populations in mood-alcohol relationships, but this nomothetic approach failed to characterize accurately the relationship between mood and alcohol use in approximately half of the subjects in two samples that were demographically and clinically homogeneous. Given inconsistent findings in the mood-alcohol relationships to date, we conclude that idiographic causal analyses can provide a foundation for more accurate theories of mood and alcohol use. In addition, idiographic causal models may also help improve psychosocial treatments through direct use in clinical settings.

RESUMEN

PURPOSE: This overview of the current landscape of quantitative magnetic resonance imaging biomarkers (qMR IBs) aims to support the standardisation of academic IBs to assist their translation to clinical practice. METHODS: We used three complementary approaches to investigate qMR IB use and quality management practices within the UK: 1) a literature search of qMR and quality management terms during 2011-2015 and 2016-2020; 2) a database search for clinical research studies using qMR IBs during 2016-2020; and 3) a survey to ascertain the current availability and quality management practices for clinical MRI scanners and associated equipment at research institutions across the UK. RESULTS: The analysis showed increased use of all qMR methods between the periods 2011-2015 and 2016-2020 and diffusion-tensor MRI and volumetry to be popular methods. However, the "translation ratio" of journal articles to clinical research studies was higher for qMR methods that have evidence of clinical translation via a commercial route, such as fat fraction and T2 mapping. The number of journal articles citing quality management terms doubled between the periods 2011-2015 and 2016-2020; although, its proportion relative to all journal articles only increased by 3.0%. The survey suggested that quality assurance (QA) and quality control (QC) of data acquisition procedures are under-reported in the literature and that QA/QC of acquired data/data analysis are under-developed and lack consistency between institutions. CONCLUSIONS: We summarise current attempts to standardise and translate qMR IBs, and conclude by outlining the ideal quality management practices and providing a gap analysis between current practice and a metrological standard.

RESUMEN

We are not aware of any validated sexual health communication scales for use with young men who have sex with men (YMSM). We used data from an HIV prevention study in Lebanon with 226 YMSM aged 18-29 to assess the psychometric characteristics of our scale, Judgmental Communication with Peers about Sex (JCPS). The construct validity of the JCPS scale was supported by it being negatively correlated with general social support, percentage of alters perceived to be supportive, and the percentage of peers who are perceived to use condoms. The scale was positively correlated with gay-related discrimination, feeling part of the gay community, and gay social integration. These findings reflect a reliable, valid measure to assess judgmental sexual health communication between YMSM.

RESUMEN

Socioeconomic deprivation is associated with greater alcohol problems despite lower alcohol consumption, but the mechanisms underpinning this alcohol harm paradox remain obscure. Fragmented published evidence collectively supports a multistage causal risk pathway wherein socioeconomic deprivation increases the probability of exposure to aversive experience, which promotes internalizing symptoms (depression and anxiety), which promotes drinking alcohol to cope with negative affect, which in turn accelerates the transition from alcohol use to dependence. To evaluate this proposed risk pathway, 219 hazardous drinkers from an undergraduate population completed questionnaires assessing these constructs in a single, cross sectional, online survey. Partial correlation coefficients revealed that each variable showed the strongest unique association with the next variable in the proposed multistage model, when adjusting for the other variables. Bootstrapped serial mediation analysis revealed that the indirect pathway linking all the variables in the proposed serial order was significant, while all other permutations were non-significant. Network centrality analysis corroborated the serial order of this indirect path. Finally, risk ratios estimated by categorizing the variables suggested that socioeconomic deprivation increased the risk of aversive experience by 32%, which increased the risk of internalizing symptoms by 180%, which increased the risk of drinking to cope by 64%, which increased susceptibility to alcohol dependence by 59%. These preliminary findings need to be corroborated by future research, nevertheless, they call for prevention strategies founded on social justice and the minimization of aversive experience in socially deprived individuals to mitigate mental health problems, maladaptive coping and addiction.

RESUMEN

Perceived discrimination and medical mistrust are contributors to HIV inequities. The current study examined whether medical mistrust mediated the associations between perceived discrimination and adherence to antiretroviral therapy (ART) as well as care engagement in a sample of 304 Black adults living with HIV. Perceived discrimination and medical mistrust were measured using validated scales; ART adherence was electronically monitored for a month; care engagement was determined by medical record data. Results support significant total indirect effects from perceived discrimination (due to HIV-serostatus, race, sexual orientation) to ART adherence through three types of medical mistrust (towards healthcare organizations, one's physician, and HIV-specific mistrust). The total indirect effects were also significant for care engagement and were largely driven by mistrust towards one's own physician. Findings suggest interventions at the provider or healthcare organization levels should address medical mistrust to improve the health and well-being of Black Americans living with HIV.

RESUMEN

OBJECTIVE: To evaluate the use of tocilizumab in a community hospital setting for critically ill patients with severe COVID-19. DESIGN: A retrospective case series. SETTING: Five community hospitals within 1 urban health system. PATIENTS: Adult patients whom received tocilizumab between March 27th, 2020 to April 30th, 2020 for severe COVID-19. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Sixteen patients in total were evaluated from the 5 community hospitals. The mean (± SD) age of the patients was 53.9 ± 9.2 years, 56% were men, and the most common comorbidities present on admission were hypertension (31%) and diabetes mellitus (25%). All patients received at least 1 other treatment modality for COVID-19 (steroids, hydroxychloroquine, or convaslescent plasma). Additionally, all patients on admission to intensive care units had severe COVID-19 with 56% requiring mechanical ventilation with a pre-tocilizumab median (IQR) Pao2: Fio2 of 84 (69 - 108.6), 19% requiring vasopressor support, and inflammatory markers (CRP, LDH, ferritin, and IL-6) were elevated. The median (IQR) tocilizumab dose was 400 mg (400-600) which correlated with a weight-based mean (± SD) dose of 5.4 mg/kg ± 1.3. Of the 16 patients that received tocilizumab, 8 (50%) were discharged home, 7 (44%) died, and 1 (6%) was still hospitalized at the end of data collection. Patients who died were more likely to be older 62 ± 2 years, female (57%), had a higher rate of mechanical ventilation (86%) and vasopressors (43%) use at baseline, and had a higher median (IQR) IL-6 level prior to tocilizumab administration 550 pg/mL (IQR 83-1924). There were no reported adverse drug reactions reported after the administration of tocilizumab for any patient. CONCLUSIONS: Our findings do not support the effectiveness of tocilizumab in treatment of severe COVID-19 infection in critically ill patients.

RESUMEN

We evaluated the effects of a culturally adapted evidence-based HIV prevention intervention (Mpowerment), named "Tayf", on condom use and HIV testing among young men who have sex with men (YMSM) in Beirut. A 2-year implementation of Tayf was carried out independently and in parallel with a research cohort of 226 YMSM who were surveyed at baseline and months 6, 12, 18 and 24 after Tayf initiation. Primary outcomes were (1) any condomless anal sex with HIV-positive or unknown status partners in the past 3 months, and (2) HIV testing in the past six months. Hierarchical logistic regression models examined the association of Tayf participation with the outcomes averaged across all assessments, and the moderating effect of Tayf participation on change in the outcomes over the follow-up period. A total of 331 YMSM attended at least one event, including 33% of the cohort. Tayf participation was associated with a higher rate of any condomless sex with HIV-positive or unknown status partners averaged across the five assessments, but there was no moderating effect of Tayf participation on change in this outcome over time. Tayf participation was associated with higher HIV testing when averaged across all assessments, but its interaction with time showed that the strength of this association diminished over time. In conclusion, Tayf proved feasible and acceptable in Beirut, but with limited effects. Further work is needed, including innovative publicity and marketing strategies, to bolster effects in high stigma settings where security and legal risks are prominent.

RESUMEN

This article describes the University of Minnesota Medical School Proposal Preparation Program (P3). P3 is designed to develop grant-writing skills for assistant professors preparing their first K- or R-series application to the National Institutes of Health (NIH). Three 4-month P3 cycles are conducted annually. For each cycle, a cohort of around 10 assistant professor participants and 5 regular faculty mentors meet for ten ~2-hour group sessions. Participants receive iterative oral and written feedback on their proposals in development within a small, interdisciplinary, group mentoring setting providing structure, accountability, guidance, and support. Between sessions, 1 peer and 1 mentor are assigned (on a rotating basis) to critique each participant's developing application. The sessions include a brief mentor-led presentation on a particular grant section followed by discussion of each participant's application conducted by the assigned reviewers. The cycle concludes with a mock NIH review session, in which each participant is matched with a University of Minnesota faculty content expert who critiques their completed application using NIH guidelines. In a survey sent to all past P3 participants as of 2018 (n = 194), 88% of respondents reported having submitted their P3-developed NIH grant, and 35% of these submitters reported funding success. A separate analysis of institutional data for all past P3 participants as of 2016 (n = 165) showed that 73% submitted at least 1 NIH proposal since completing P3 and that 43% of these had acquired NIH funding, for a combined total of $193 million in funding awarded. The estimated rate at which participants obtained funding for their P3-developed grant application (~35%) exceeds the national annual NIH grant funding rates (~20%) by approximately 50%. This article provides the practical information needed for other institutions to implement a P3-like program and presents a cost-benefit analysis showing the advantages of doing so.
