RESUMO

Transposable elements (TEs) are often expressed at higher levels in tumor cells than normal cells, implicating these genomic regions as an untapped pool of tumor-associated antigens. In ovarian cancer (OC), protein from the TE ERV-K is frequently expressed by tumor cells. Here we determined whether the targeting of previously identified epitope in the envelope gene (env) of ERV-K resulted in target antigen specificity against cancer cells. We found that transducing healthy donor T cells with an ERV-K-Env-specific T cell receptor construct resulted in antigen specificity only when co-cultured with HLA-A*03:01 B lymphoblastoid cells. Furthermore, in vitro priming of several healthy donors with this epitope of ERV-K-Env did not result in target antigen specificity. These data suggest that the T cell receptor is a poor candidate for targeting this specific ERV-K-Env epitope and has limited potential as a T cell therapy for OC.

RESUMO

PURPOSE: The European Society of Intensive Care Medicine (ESICM) Green Paper aims to address the challenge of environmental sustainability in intensive care and proposes actionable strategies for integrating sustainability into intensive care unit (ICU) stakeholder actions. METHODS: The ESICM Executive Committee appointed a task force of topic experts and ESICM committee representatives to develop the ESICM Green Paper. The task force convened biweekly from January to June 2024, identifying key domains for environmental sustainability and prioritizing actions. Drafts were iteratively refined and approved by the ESICM Executive Committee. RESULTS: Climate change will impact activities in intensive care in many ways, but also the impact of ICU activities on the environment is considerable; drivers for this include extensive resource use and waste generation in ICUs from energy consumption, use of disposable items, and advanced therapies for critically ill patients. The ESICM Green Paper outlines a structured approach for ICUs to reduce their environmental impact, emphasizing energy efficiency, waste reduction, and sustainable procurement. Furthermore, it endorses the need for awareness and education among healthcare professionals, integration of sustainability into research, and sustainable policies within scientific societies. CONCLUSIONS: The ESICM Green Paper reviewed the relevance of climate change to intensive care and provided suggestions for clinical practice, research, education, and ESICM organizational domains. It underscores that reducing intensive care's ecological footprint can coexist with high-quality patient care. Promoting a resilient, responsible healthcare system is a joint responsibility of all ICU stakeholders.

RESUMO

BACKGROUND: Internalizing disorders (IDs), primarily depression and anxiety, are highly prevalent among adolescents receiving community-based treatment for substance use disorders (SUDs). For such clients, interventions that do not holistically address both SUDs and IDs are less effective. OBJECTIVE: This pilot treatment development study aims to develop and test a modular treatment protocol for addressing cooccurring IDs among adolescents (aged 13 to 18 years) enrolled in routine care for substance use problems: Family Support Protocol for Adolescent Internalizing Disorders (Fam-AID). As an adjunctive protocol, Fam-AID will not require clinicians to markedly alter existing base practices for SUD. It will be anchored by 3 evidence-based foundations for treating cooccurring adolescent IDs: family engagement techniques, transdiagnostic individual cognitive behavioral therapy techniques, and family psychoeducation and safety planning. METHODS: This quasi-experimental study will proceed in 2 stages. The pilot stage will use rapid-cycle prototyping methods in collaboration with end-user stakeholders to draft protocol delivery and fidelity guidelines adapted from existing resources, solicit provider and client input on protocol content and delivery via cognitive interviewing, and pilot prototype components on 4 to 6 cases. The second stage will be an interrupted time series study for 60 comorbid SUD+ID cases across 2 sites serving diverse adolescents: 30 will receive treatment as usual (TAU); following clinician training in the protocol, 30 new cases will receive TAU enhanced by Fam-AID. For aim 1, the focus is on evaluating the acceptability of the Fam-AID protocol through therapist and client interviews as well as assessing fidelity benchmarks using therapist- and observer-reported protocol fidelity data. For aim 2, the plan is to compare the effects of TAU only cases versus TAU+Fam-AID cases on family treatment attendance and on adolescent ID and substance use symptoms, with measurements taken at baseline and at 3-month and 6-month follow-ups. RESULTS: Study recruitment will begin in April 2025. CONCLUSIONS: We anticipate that Fam-AID will contain 5 treatment modules that can be delivered in any sequence to meet client needs: family engagement of primary supports in treatment planning and services; relational reframing of family constraints, resiliencies, and social capital connected to the adolescent's ID symptoms; functional analysis of the adolescent's ID symptoms and related behaviors; cognitive behavioral therapy to address the adolescent's ID symptoms and functional needs, featuring 3 core techniques (emotion acceptance, emotional exposure, and behavioral activation) to address negative affect and emotional dysregulation; and family psychoeducation and safety planning focused on education about comorbid SUD+ID and prevention of adolescent self-harm. If the abovementioned modules are found to be feasible and effective, Fam-AID will offer a set of pragmatic interventions to SUD clinicians for treating cooccurring IDs in adolescent clients.

RESUMO

The interplay between the immune system, coagulation, and endothelium is critical in regulating the host response to infection. However, in sepsis and other critical illnesses, a dysregulated immune response can lead to excessive alterations in these mechanisms, resulting in coagulopathy, endothelial dysfunction, and multi-organ dysfunction. This review aims to provide a comprehensive analysis of the pathophysiological mechanisms that govern the complex interplay between immune dysfunction, endothelial dysfunction, and coagulation in sepsis. It emphasises clinical significance, evaluation methods, and potential therapeutic interventions. Understanding these mechanisms is essential for developing effective treatments that can modulate the immune response, mitigate thrombosis, restore endothelial function, and ultimately improve patient survival.

RESUMO

BACKGROUND: Opioid use disorder (OUD) among young adults (YAs) continues to persist as a national health crisis. Best practice recommendations for YA OUD treatment highlight the importance of medication for OUD (MOUD) and family involvement across the treatment services continuum for better treatment retention and outcomes. Yet, concerned significant others (CSOs) such as family members, romantic partners, and family-of-choice members are not routinely involved in OUD and MOUD treatment for YAs. METHOD: We used convenience sampling to recruit 25 YAs (ages 21 to 36) in treatment for OUD from two urban treatment centers. We discussed with YAs the identities of their CSOs and the dynamics of those relationships, their perspectives on CSO involvement in their OUD treatment, and the beliefs and attitudes they hold about family involvement in treatment and recovery. Thematic content analysis was deductive-dominant based on a semi-structured qualitative interview guide. Group consensus coding was followed by matrix analysis. RESULTS: We identified five main themes: (1) YA and CSO relationships were supportive, evolving, and complex. (2) CSO support motivated treatment engagement and participation. (3) Only a small proportion of CSOs participated in treatment activities despite actively supporting treatment in other ways. (4) YAs experienced their CSOs as supportive of their treatment and recovery goals, including MOUD. (5) YAs believed family involvement is essential to treatment and many were unsatisfied with current family involvement in their care. CONCLUSIONS: In this qualitative study of OUD treatment experiences among YAs, we learned that many YAs have CSOs who are invested in their treatment and recovery and yet are not routinely involved in treatment. Moreover, YAs often expressed family involvement is essential to OUD treatment, and many expressed a desire for greater family involvement in their own treatment. Clinical recommendations for relationship-oriented treatment are presented.

RESUMO

OBJECTIVE: This study assessed the health-related quality of life (HRQo) of women surviving a borderline ovarian tumor (BOT) in comparison with early-stage ovarian cancer survivors treated surgically alone and with a matched cancer-free population. METHODS: Survivors of BOT and ovarian cancer were invited in two Dutch cross-sectional, population-based studies. Ovarian cancer survivors with tumor stage I who were treated surgically only were included. A random sample from the cancer-free population was matched on sex, age and education to the sample of BOT survivors. The EORTC QLQ-C30 (version 3.0) and the EORTC QLQ-OV28 were completed by the cancer-free population and the BOT and ovarian cancer survivors in study 1 and 2. The Hospital Anxiety and Depression Scale (HADS) was only completed by the cancer-free population and the survivors of BOT and ovarian cancer in study 1. BOT survivors were compared to early-stage ovarian cancer survivors and the general population using linear regression analyses and effect sizes regarding clinical importance. RESULTS: 83 BOT (42%), 88 early-stage ovarian cancer survivors (52%), and 82 women from the general population were included. In most HRQoL domains, BOT survivors were not significantly different from early-stage ovarian cancer survivors and the cancer-free population, except that BOT survivors reported significantly less insomnia than early-stage ovarian cancer survivors and more dyspnea than the cancer-free population (small clinical difference). CONCLUSION: In general, BOT survivors' HRQoL lies between the HRQoL of early-stage ovarian cancer survivors and of the cancer-free population, but clinical effect sizes between the groups were mostly only trivial.

RESUMO

BACKGROUND: Trauma induced coagulopathy remains to be an important cause of high transfusion requirements and mortality and shock induced endotheliopathy (SHINE) has been implicated. METHODS: European multicenter observational study of adult trauma patients with injury severity score ≥ 16 arriving within 2 h from injury to the trauma centers. Admission blood samples obtained were used for analysis of the SHINE biomarkers (syndecan-1, soluble thrombomodulin, adrenaline) and extensive analysis of coagulation, -and fibrinolytic factors together with collection of clinical data. Hierarchical clustering of the SHINE biomarkers was used to identify the SHINE phenotypes. RESULTS: The 313 patients clustered into four SHINE phenotypes. Phenotype 2, having the highest glycocalyx shedding, encompassing 22% of the whole cohort, had severe coagulopathy with lower levels of prothrombin, FV, IX, X, XI and severe hyperfibrinolysis with higher plasmin - alpha 2-antiplasmin (PAP) - and tPA levels and lower alpha2 - antiplasmin levels. This phenotype had significantly higher transfusion requirements and higher mortality (39% vs. 23%, 15% and 14%) but similar injury severity score (ISS) compared to the others phenotypes. CONCLUSIONS: Hierarchical clustering identified four SHINE phenotype in a cohort of trauma patients. Trauma induced coagulopathy was confined to only one of the SHINE phenotypes, encompassing 22% of the total cohort. This phenotype was characterized by severe hypocoagulability and hyperfibrinolysis, which translated to significantly higher transfusion requirements and higher mortality compared to the other SHINE phenotypes with similar injury severity, warranting further investigation.

RESUMO

Limited guidance exists on streamlining cancer therapy for adolescent and young adult (AYA) patients 15-39 years of age, as much of the current data are extrapolated from pediatric or adult counterparts and can differ significantly between the two care models. Harmonization of standard treatment approaches has the potential to improve outcomes and establish a foundation for the development of future clinical trials. We present our experience harmonizing treatment and supportive care regimens for AYA patients with osteosarcoma receiving treatment with methotrexate, doxorubicin, and cisplatin (MAP) therapy on the pediatric and adult sarcoma services at the Memorial Sloan Kettering Cancer Center.

RESUMO

The clover seed weevil, Tychius picirostris Fabricius (Coleoptera: Curculionidae), is a major pest in Oregon white clover seed crops. Reliance on synthetic pyrethroid insecticides and limited availability of diverse modes of action (MoAs) has increased insecticide resistance selection in regional T. picirostris populations, emphasizing the need to evaluate novel chemistries and rotational strategies for effective insecticide resistance management (IRM). The efficacy of 8 foliar insecticide formulations for managing T. picirostris adult and larval life stages was determined in small and large-plot field trials across 2 crop years. In both years, bifenthrin (Brigade 2EC), the grower's standard, showed negligible adult and larval suppression. Insecticide formulations with isocycloseram and cyantraniliprole active ingredients reduced adult and larval populations when applied at BBCH 59-60 (prebloom) and BBCH 65-66 (full bloom) growth stages, respectively. While differences in T. picirostris abundance were observed among insecticide treatments, seed yield differences were not detected in large-plot trials. Larval abundance was correlated with reduced seed yield, and an economic threshold of ≥3 larvae per 30 inflorescences was determined as a conservative larval threshold to justify foliar applications of diamide insecticides. Additional commercial white clover seed fields were surveyed to compare larval scouting techniques, including a standard Berlese funnel and a grower's do-it-yourself funnel. Both larval extraction techniques were correlated and provided similar estimates of larval abundance. These findings demonstrate new MoAs, optimal insecticide application timing, and larval monitoring methods that can be incorporated into an effective T. picirostris IRM program in white clover seed crops.

RESUMO

Violence against women is a global public health problem. CDC data shows 41% of US women have experienced intimate partner violence. Burn-related violence against women is an extremely confronting form of physical violence. The aim of this study was to describe the frequency, demographics, injury characteristics and outcomes of women admitted to US burn centers who have experienced burn violence compared to those with accidental burn injuries. 2008-2018 data was queried from the ABA Burn Quality Care Platform registry for patients that were women and ≥18 years old. Women who experienced an assault or accidental burn injury were included. Women who experienced self-harm were excluded. Descriptive/simple comparative statistics were used to describe/compare groups. 54,523 women met study inclusion criteria. 956 (2%) experienced burn violence. Women who experienced burn violence had a younger median [IQR] age (36 [27,48] vs 47 [32,61],p<0.0001), were Black/African American (44.5% vs. 22.4%,p< 0.0001), were covered by Medicaid (38.8% vs. 21.6%,p< 0.0001), had a higher median [IQR] %TBSA extent (6.0% [3,15.2] vs. 3.0% [1,7.3],p< 0.0001), a higher proportion with 3rd degree burns (35.4% vs. 28.9%,p<0.0001), and a higher proportion with TBSA >20% (18.2% vs. 6.7%,p<0.0001). Scald/flame injuries were the most frequent mechanism of injury. Women who experienced violence had a higher median [IQR] length of hospital stay (7.0 [2,18] vs. 4.0 [1,11] days, p< 0.0001), ICU stay (8.5 [2,27] vs. 4 [2,13] days,p< 0.0001), and mortality rate (5.7% vs 4.3%,p<0.04). The frequency of women who sustained burn violence appears small yet experience worse outcomes. Clinicians should be aware of these demographic/clinical characteristics to provide optimal care to this vulnerable population.

RESUMO

Abscisic acid (ABA) is crucial for plant water deficit (WD) acclimation, but how the interplay between ABA and guard cell (GC) metabolism aids plant WD acclimation remains unclear. Here, we investigated how ABA regulates GC metabolism and how this contributes to plant WD acclimation using tomato wild type (WT) and the ABA-deficient sitiens mutant. These genotypes were characterized at physiological, metabolic, and transcriptional levels under recurring WD periods and were used to perform a13C-glucose labelling experiment using isolated guard cells following exogenously applied ABA. ABA deficiency altered the level of sugars and organic acids in GCs in both irrigated and WD plants and the dynamic of accumulation/degradation of these compounds in GCs during the dark-to-light transition. WD-induced metabolic changes were more pronounced in sitiens than WT GCs. Results from the 13C-labelling experiment indicate that ABA is required for the glycolytic fluxes toward malate and acts as a negative regulator of a putative sucrose substrate cycle. The expression of key ABA-biosynthetic genes was higher in WT than in sitiens GCs after two cycles of WD. Additionally, the intrinsic leaf water use efficiency increased only in WT after the second WD cycle, compared to sitiens. Our results highlight that ABA deficiency disrupts the homeostasis of GC primary metabolism and the WD memory, negatively affecting plant WD acclimation. Our study demonstrates which metabolic pathways are activated by WD and/or regulated by ABA in GCs, which improves our understanding of plant WD acclimation, with clear consequences for plant metabolic engineering in the future.

RESUMO

BACKGROUND: Evidence on the optimal follow-up schedule after endometrial cancer is lacking. The study aim was to compare satisfaction with care between women who received reduced follow-up care and women who received usual guideline-directed follow-up care for three years after surgery. METHODS: The ENSURE (ENdometrial cancer SURvivors' follow-up carE) trial was a non-inferiority randomized controlled multicenter trial in 42 hospitals in the Netherlands. The intervention arm received reduced follow-up care (4 visits/3 years), while the control group received usual follow-up care (8-11 visits/3 years). Primary outcome was overall satisfaction with care, PSQIII score, over three years follow-up, with a non-inferiority margin of 6. Mixed linear regression, intention-to-treat and per-protocol analyses (presented below) were used. RESULTS: Among 316 women included, overall satisfaction with care was not lower in the reduced follow-up (mean 82; SD = 15) compared with the usual follow-up group (mean 80; SD = 15) group (B = 1.80(-2.09;5.68)). At 6, 12 and 36 months, more women (93/94/90%) in the reduced follow-up group were satisfied with their follow-up schedule than in the usual follow-up group (79/79/82%; p < 0.001; p < 0.001; p = 0.050). CONCLUSIONS AND RELEVANCE: Women with low-risk, early-stage endometrial cancer who received reduced follow-up care were no less satisfied with their care than women receiving usual follow-up care. Compared with usual follow-up, women in the reduced follow-up group had fewer clinical visits and, at the same time, more often reported being satisfied with their follow-up schedule. Findings suggest that reduced follow-up care may be the new standard, but should be tailored to meet additional needs where indicated.

RESUMO

INTRODUCTION: In the Netherlands, most emergency department (ED) patients are referred by a general practitioner (GP) or a hospital specialist. Early risk stratification during telephone referral could allow the physician to assess the severity of the patients' illness in the prehospital setting. We aim to assess the discriminatory value of the acute internal medicine (AIM) physicians' clinical intuition based on telephone referral of ED patients to predict short-term adverse outcomes, and to investigate on which information their predictions are based. METHODS: In this prospective study, we included adult ED patients who were referred for internal medicine by a GP or a hospital specialist. Primary outcomes were hospital admission and triage category according to the Manchester Triage System (MTS). Secondary outcome was 31-day mortality. The discriminatory performance of the clinical intuition was assessed using an area under the receiver operating characteristics curve (AUC). To identify which information is important to predict adverse outcomes, we performed univariate regression analysis. Agreement between predicted and observed MTS triage category was assessed using intraclass and Spearman's correlation. RESULTS: We included 333 patients, of whom 172 (51.7%) were referred by a GP, 146 (43.8%) by a hospital specialist, and 12 (3.6%) by another health professional. The AIM physician's clinical intuition showed good discriminatory performance regarding hospital admission (AUC 0.72, 95% CI: 0.66-0.78) and 31-day mortality (AUC 0.73, 95% CI: 0.64-0.81). Univariate regression analysis showed that age ≥65 years and a sense of alarm were significant predictors. The predicted and observed triage category were similar in 45.2%, but in 92.5% the prediction did not deviate by more than one category. Intraclass and Spearman's correlation showed fair agreement between predicted and observed triage category (ICC 0.48, Spearman's 0.29). CONCLUSION: Clinical intuition based on relevant information during a telephone referral can be used to accurately predict short-term outcomes, allowing for early risk stratification in the prehospital setting and managing ED patient flow more effectively.

RESUMO

OBJECTIVES: Describing mitochondrial oxygenation (mitoPO2) and its within- and between-subject variability over time after 5-aminolevulinic acid (ALA) plaster application in healthy volunteers. DESIGN: Prospective cohort study. SETTING: Measurements were performed in Leiden University Medical Center, the Netherlands. PARTICIPANTS: Healthy volunteers enrolled from July to September 2020. INTERVENTIONS: Two ALA plasters were placed parasternal left and right, with a 3-hour time interval, to examine the influence of the calendar time on the value of mitoPO2. We measured mitoPO2 at 4, 5, 7, 10, 28, and 31 hours after ALA plaster 1 application, and at 4, 5, 7, 25, and 28 hours after ALA plaster 2 application. PRIMARY AND SECONDARY OUTCOME MEASURES: At each time point, five mitoPO2 measurements were performed. Within-subject variability was defined as the standard deviation (SD) of the mean of five measurements per timepoint of a study participant. The between-subject variability was the SD of the mean mitoPO2 value of the study population per timepoint. RESULTS: In 16 completed inclusions, median mitoPO2 values and within-subject variability were relatively similar over time at all time points for both plasters. An increase in overall between-subject variability was seen after 25 hours ALA plaster time (19.6 mm Hg vs 23.9 mm Hg after respectively 10 and 25 hours ALA plaster time). CONCLUSIONS: The mitoPO2 values and within-subject variability remained relatively stable over time in healthy volunteers. An increase in between-subject variability was seen after 25 hours ALA plaster time warranting replacement of the ALA plaster one day after its application. TRIAL REGISTRATION: ClinicalTrials.gov with trial number NCT04626661.

RESUMO

We aimed to identify the minimum number of ambulatory blood pressure (ABP) measures to accurately determine daytime and nighttime systolic blood pressure (BP) averages and nocturnal dipping status (i.e., relative daytime:nighttime change). A total of 43 midlife participants wore an ABP monitor for 24 h with measurements every 20/30 min during the daytime/nighttime, as identified by a sleep diary. We calculated daytime/nighttime systolic BP average and dipping status from all available measurements per participant (i.e., normative data). We then calculated daytime and nighttime BP per participant based on a random selection of 8-20 and 4-10 measurements and replicated random selections 1,000 times. We calculated accuracy by checking the proportion from 1,000 different randomly selected samples for a particular number of measurements that systolic BP was ±5 mmHg of normative data, and dipping status remained unchanged for each participant compared with the normative value. The best fit for the regression model estimated the minimal number of measurements for an accuracy of 95% in BP averages. For a 95% accuracy in estimating daytime and nighttime systolic BP, 11 daytime and 8 nighttime measurements were required. The highest accuracy for dipping status was 91.6 ± 13.4% using 20 daytime and 10 nighttime measures, while the lowest was (83.4 ± 15.1%) using 8 daytime and 4 nighttime measures. In midlife adults, 11 daytime and 8 nighttime measurements are likely enough to calculate average systolic BPs accurately. However, no minimum number is suggested to accurately calculate dipping status.NEW & NOTEWORTHY We found that a minimum of 11 blood pressure (BP) measures are necessary to calculate an accurate average daytime BP, and 8 nighttime measures are necessary to calculate an accurate nighttime average if 95% accuracy is acceptable. Regarding BP dipping status, the current recommendations (20 daytime/7 nighttime) inaccurately classified the dipping status 10.5% of the time, suggesting that guidelines may need to be updated to classify patients as nocturnal dippers or nondippers correctly.

RESUMO

Background: Cardiovascular diseases are the leading cause of morbidity and mortality in the United States. Despite the complexity of cardiovascular disease etiology, we do not fully comprehend the interactions between non-modifiable factors (e.g., age, sex, and race) and modifiable risk factors (e.g., health behaviors and occupational exposures). Objective: We examined proximal and distal drivers of cardiovascular disease and elucidated the interactions between modifiable and non-modifiable risk factors. Methods: We used a machine learning approach on four cohorts (2005-2012) of the National Health and Nutrition Examination Survey data to examine the effects of risk factors on cardiovascular risk quantified by the Framingham Risk Score (FRS) and the Pooled Cohort Equations (PCE). We estimated a network of risk factors, computed their strength centrality, closeness, and betweenness centrality, and computed a Bayesian network embodied in a directed acyclic graph. Results: In addition to traditional factors such as body mass index and physical activity, race and ethnicity and exposure to heavy metals are the most adjacent drivers of PCE. In addition to the factors directly affecting PCE, sleep complaints had an immediate adverse effect on FRS. Exposure to heavy metals is the link between race and ethnicity and FRS. Conclusion: Heavy metal exposures and race/ethnicity have similar proximal effects on cardiovascular disease risk as traditional clinical and lifestyle risk factors, such as physical activity and body mass. Our findings support the inclusion of diverse racial and ethnic groups in all cardiovascular research and the consideration of the social environment in clinical decision-making.

RESUMO

Parotid abscesses are sequelae of acute parotitis that are rare in pediatric patients. Common inciting causes of parotid abscesses include infection, inflammatory conditions, and ductal obstruction. This case presents a parotid abscess found in an otherwise healthy four-year-old girl. Further evaluation revealed no evidence of infection, no anatomical ductal obstruction, and no evidence of autoimmune conditions that could have caused the abscess. Nonetheless, the patient was treated with an incision and drainage procedure and antibiotic therapy with full recovery. Development of a parotid abscess with no identifiable cause is exceedingly rare with limited documented instances. From this case, idiopathic parotid abscesses may be considered as a diagnosis of exclusion after ruling out common causes, though management still follows the standard of care.

RESUMO

BACKGROUND: Acute respiratory distress syndrome (ARDS) is characterized by alveolar edema that can progress to septal fibrosis. Mechanical ventilation can augment lung injury, termed ventilator-induced lung injury (VILI). Connective tissue growth factor (CTGF), a mediator of fibrosis, is increased in ARDS patients. Blocking CTGF inhibits fibrosis and possibly vascular leakage. This study investigated whether neutralizing CTGF reduces pulmonary edema in VILI. METHODS: Following LPS administration, rats were mechanically ventilated for 6 h with low (6 mL/kg; low VT) or moderate (10 mL/kg; mod VT) tidal volume and treated with a neutralizing CTGF antibody (FG-3154) or placebo lgG (vehicle). Control rats without LPS were ventilated for 6 h with low VT. Lung wet-to-dry weight ratio, FITC-labeled dextran permeability, histopathology, and soluble RAGE were determined. RESULTS: VILI was characterized by reduced PaO2/FiO2 ratio (low VT: 540 [381-661] vs. control: 693 [620-754], p < 0.05), increased wet-to-dry weight ratio (low VT: 4.8 [4.6-4.9] vs. control: 4.5 [4.4-4.6], p < 0.05), pneumonia (low VT: 30 [0-58] vs. control: 0 [0-0]%, p < 0.05) and interstitial inflammation (low VT: 2 [1-3] vs. control: 1 [0-1], p < 0.05). FG-3154 did not affect wet-to-dry weight ratio (mod VT + FG-3154: 4.8 [4.7-5.0] vs. mod VT + vehicle: 4.8 [4.8-5.0], p > 0.99), extravasated dextrans (mod VT + FG-3154: 0.06 [0.04-0.09] vs. mod VT + vehicle: 0.04 [0.03-0.09] µg/mg tissue, p > 0.99), sRAGE (mod VT + FG-3154: 1865 [1628-2252] vs. mod VT + vehicle: 1885 [1695-2159] pg/mL, p > 0.99) or histopathology. CONCLUSIONS: 'Double hit' VILI was characterized by inflammation, impaired oxygenation, pulmonary edema and histopathological lung injury. Blocking CTGF does not improve oxygenation nor reduce pulmonary edema in rats with VILI.

RESUMO

BACKGROUND: Screening, brief intervention, and referral to treatment for adolescents (SBIRT-A) is widely recommended to promote detection and early intervention for alcohol and other drug (AOD) use in pediatric primary care. Existing SBIRT-A procedures rely almost exclusively on adolescents alone, despite the recognition of caregivers as critical protective factors in adolescent development and AOD use. Moreover, controlled SBIRT-A studies conducted in primary care have yielded inconsistent findings about implementation feasibility and effects on AOD outcomes and overall developmental functioning. There is urgent need to investigate the value of systematically incorporating caregivers in SBIRT-A procedures. OBJECTIVE: This randomized effectiveness trial will advance research and scope on SBIRT-A in primary care by conducting a head-to-head test of 2 conceptually grounded, evidence-informed approaches: a standard adolescent-only approach (SBIRT-A-Standard) versus a more expansive family-based approach (SBIRT-A-Family). The SBIRT-A-Family approach enhances the procedures of the SBIRT-A-Standard approach by screening for AOD risk with both adolescents and caregivers; leveraging multidomain, multireporter AOD risk and protection data to inform case identification and risk categorization; and directly involving caregivers in brief intervention and referral to treatment activities. METHODS: The study will include 2300 adolescents (aged 12-17 y) and their caregivers attending 1 of 3 hospital-affiliated pediatric settings serving diverse patient populations in major urban areas. Study recruitment, screening, randomization, and all SBIRT-A activities will occur during a single pediatric visit. SBIRT-A procedures will be delivered digitally on handheld tablets using patient-facing and provider-facing programming. Primary outcomes (AOD use, co-occurring behavior problems, and parent-adolescent communication about AOD use) and secondary outcomes (adolescent quality of life, adolescent risk factors, and therapy attendance) will be assessed at screening and initial assessment and 3-, 6-, 9-, and 12-month follow-ups. The study is well powered to conduct all planned main and moderator (age, sex, race, ethnicity, and youth AOD risk status) analyses. RESULTS: This study will be conducted over a 5-year period. Provider training was initiated in year 1 (December 2023). Participant recruitment and follow-up data collection began in year 2 (March 2024). We expect the results from this study to be published in early 2027. CONCLUSIONS: SBIRT-A is widely endorsed but currently underused in pediatric primary care settings, and questions remain about optimal approaches and overall effectiveness. In particular, referral to treatment procedures in primary care remains virtually untested among youth. In addition, whereas research strongly supports involving families in interventions for adolescent AOD, SBIRT-A effectiveness trial testing approaches that actively engage family members in primary care are absent. This trial is designed to help fill these research gaps to inform the critical health decision of whether and how to include caregivers in SBIRT-A activities conducted in pediatric primary care.
