RESUMEN

E2F transcription factors are master regulators of the eukaryotic cell cycle. In Drosophila, the sole activating E2F, E2F1, is both required for and sufficient to promote G1→S progression. E2F1 activity is regulated both by binding to RB Family repressors and by posttranscriptional control of E2F1 protein levels by the EGFR and TOR signaling pathways. Here, we investigate cis-regulatory elements in the E2f1 messenger RNA (mRNA) that enable E2f1 translation to respond to these signals and promote mitotic proliferation of wing imaginal disc and intestinal stem cells. We show that small upstream open reading frames (uORFs) in the 5' untranslated region (UTR) of the E2f1 mRNA limit its translation, impacting rates of cell proliferation. E2f1 transgenes lacking these 5'UTR uORFs caused TOR-independent expression and excess cell proliferation, suggesting that TOR activity can bypass uORF-mediated translational repression. EGFR signaling also enhanced translation but through a mechanism less dependent on 5'UTR uORFs. Further, we mapped a region in the E2f1 mRNA that contains a translational enhancer, which may also be targeted by TOR signaling. This study reveals translational control mechanisms through which growth signaling regulates cell cycle progression.

RESUMEN

Newborn screening (NBS) was established as a public health program in the 1960s and is crucial for facilitating detection of certain medical conditions in which early intervention can prevent serious, life-threatening health problems. Genomic sequencing can potentially expand the screening for rare hereditary disorders, but many questions surround its possible use for this purpose. We examined the use of exome sequencing (ES) for NBS in the North Carolina Newborn Exome Sequencing for Universal Screening (NC NEXUS) project, comparing the yield from ES used in a screening versus a diagnostic context. We enrolled healthy newborns and children with metabolic diseases or hearing loss (106 participants total). ES confirmed the participant's underlying diagnosis in 15 out of 17 (88%) children with metabolic disorders and in 5 out of 28 (∼18%) children with hearing loss. We discovered actionable findings in four participants that would not have been detected by standard NBS. A subset of parents was eligible to receive additional information for their child about childhood-onset conditions with low or no clinical actionability, clinically actionable adult-onset conditions, and carrier status for autosomal-recessive conditions. We found pathogenic variants associated with hereditary breast and/or ovarian cancer in two children, a likely pathogenic variant in the gene associated with Lowe syndrome in one child, and an average of 1.8 reportable variants per child for carrier results. These results highlight the benefits and limitations of using genomic sequencing for NBS and the challenges of using such technology in future precision medicine approaches.

RESUMEN

BACKGROUND: Multiple reviews have identified a lack of evidence-based treatments for excessive anxiety in the context of food allergy (FAA) as an unmet need. OBJECTIVE: To evaluate the feasibility, acceptability, and proof of concept of Food Allergy Bravery (FAB), a brief, novel, manualized cognitive-behavioral-based intervention for anxiety in a clinical sample of children with FAA. METHODS: A total of 3 cohorts of children (aged 8 to 12 years) with clinically impairing FAA and their parents were offered a course of FAB delivered in a group format. Ratings of anxiety severity and quality of life were collected at pretreatment, posttreatment, and 2- to 4-month follow-up. RESULTS: All families offered treatment completed the full course of FAB, attended at least 5 of 6 active treatment sessions, and rated the intervention as highly satisfactory. All children were rated as very much improved or much improved on the Clinician Global Impression scale at posttreatment. Anxiety severity scores on the Scale of Food Allergy Anxiety and the Scale of Child Anxiety-Related Emotional Disorders significantly declined per both child and parent reports. Scores on the Food Allergy Quality of Life Questionnaire-Parent Form were significantly improved. Gains were maintained at follow-up. CONCLUSION: This is the first study of an outpatient manualized psychosocial treatment for FAA in a clinically ascertained sample of children. Findings provide initial evidence of feasibility, acceptability, and proof of concept for the FAB intervention protocol. Randomized controlled trials are needed.

RESUMEN

As new variants of SARS-Co-V 2 have emerged over time and Omicron sub-variants have become dominant, the severity of illness from COVID-19 has declined despite greater transmissibility. There are fewer data on how the history, diagnosis, and clinical characteristics of multisystem inflammatory syndrome in children (MIS-C) have changed with evolution in SARS-CoV-2 variants. We conducted a retrospective cohort study of patients hospitalized with MIS-C between April 2020 and July 2022 in a tertiary referral center. Patients were sorted into Alpha, Delta, and Omicron variant cohorts by date of admission and using national and regional data on variant prevalence. Among 108 patients with MIS-C, significantly more patients had a documented history of COVID-19 in the two months before MIS-C during Omicron (74%) than during Alpha (42%) (p = 0.03). Platelet count and absolute lymphocyte count were lowest during Omicron, without significant differences in other laboratory tests. However, markers of clinical severity, including percentage with ICU admission, length of ICU stay, use of inotropes, or left ventricular dysfunction, did not differ across variants. This study is limited by its small, single-center case series design and by classification of patients into era of variant by admission date rather than genomic testing of SARS- CoV-2 samples.     Conclusion: Antecedent COVID-19 was more often documented in the Omicron than Alpha or Delta eras, but clinical severity of MIS-C was similar across variant eras. What is Known: • There has been a decrease in incidence of MIS-C in children despite widespread infection with new variants of COVID-19. • Data has varied on if the severity of MIS-C has changed over time across different variant infections. What is New: • MIS-C patients were significantly more likely to report a known prior infection with SARS-CoV-2 during Omicron than during Alpha. • There was no difference in severity of MIS-C between the Alpha, Delta, and Omicron cohorts in our patient population.

RESUMEN

CONTEXT: Digital video-based behavioral interventions are effective tools for improving HIV care and treatment outcomes. OBJECTIVE: To assess the costs of the Positive Health Check (PHC) intervention delivered in HIV primary care settings. DESIGN, SETTING, AND INTERVENTION: The PHC study was a randomized trial evaluating the effectiveness of a highly tailored, interactive video-counseling intervention delivered in 4 HIV care clinics in the United States in improving viral suppression and retention in care. Eligible patients were randomized to either the PHC intervention or the control arm. Control arm participants received standard of care (SOC), and intervention arm participants received SOC plus PHC. The intervention was delivered on computer tablets in the clinic waiting rooms. The PHC intervention improved viral suppression among male participants. A microcosting approach was used to assess the program costs, including labor hours, materials and supplies, equipment, and office overhead. PARTICIPANTS: Persons with HIV infection, receiving care in participating clinics. MAIN OUTCOME MEASURES: The primary outcome was the number of patients virally suppressed, defined as having fewer than 200 copies/mL by the end of their 12-month follow-up. RESULTS: A total of 397 (range across sites [range], 95-102) participants were enrolled in the PHC intervention arm, of whom 368 participants (range, 82-98) had viral load data at baseline and were included in the viral load analyses. Of those, 210 (range, 41-63) patients were virally suppressed at the end of their 12-month follow-up visit. The overall annual program cost was $402 274 (range, $65 581-$124 629). We estimated the average program cost per patient at $1013 (range, $649-$1259) and the cost per patient virally suppressed at $1916 (range, $1041-$3040). Recruitment and outreach costs accounted for 30% of PHC program costs. CONCLUSIONS: The costs of this interactive video-counseling intervention are comparable with other retention in care or reengagement interventions.

RESUMEN

BACKGROUND: Mobilization is a key component in the recovery of those admitted to critical care. However, previous research has demonstrated challenges in the implementation of mobilization within critical care, including staff knowledge, attitudes, and behaviours. AIM: The aim of the current study was to explore the perceived barriers and limitations to mobilization from the perspective of nursing staff, and to compare these with physiotherapists. STUDY DESIGN: Single-site service evaluation utilizing the patient mobilizations attitudes and beliefs survey for ICU and locally developed barriers to rehabilitation questionnaire. RESULTS: About 135 participants (126 nurses and 9 physiotherapists) were invited to anonymously complete the questionnaires (either paper or electronic), with a response rate of 73.0% (n = 92) for nursing staff and 100% for physiotherapists. Nursing staff reported significantly higher perceived barriers to rehabilitation on both questionnaires when compared with physiotherapy staff, which was not associated with years of experience within critical care. Behavioural barriers were most frequent in both professions which included items such as time availability and presence of perceived contra-indications to mobilization. CONCLUSION: Nursing staff reported greater perceived barriers to rehabilitation when compared with physiotherapists. Further quality improvement projects are now required to reduce these barriers and assist the implementation of mobilization as part of the rehabilitation process. RELEVANCE TO CLINICAL PRACTICE: Rehabilitation is an essential element of practice within critical care. Understanding the system, local and personal barriers will allow for improvement projects to enhance the delivery of care and improve clinical outcomes.

RESUMEN

Early-life inflammatory stress increases seizure susceptibility later in life. However, possible sex- and age-specific differences and the associated mechanisms are largely unknown. C57BL/6 mice were bred in house, and female and male pups were injected with lipopolysaccharide (LPS; 100 µg/kg, i.p.) or vehicle control (saline solution) at postnatal day 14 (P14). Seizure threshold was assessed in response to pentylenetetrazol (1% solution, i.v.) in adolescence (∼P40) and adulthood (∼P60). We found that adult, but not adolescent, mice treated with LPS displayed ∼34% lower seizure threshold compared with controls. Females and males showed similar increased seizure susceptibility, suggesting that altered brain excitability was age dependent, but not sex dependent. Whole-cell recordings revealed no differences in excitatory synaptic activity onto CA1 pyramidal neurons from control or neonatally inflamed adolescent mice of either sex. However, adult mice of both sexes previously exposed to LPS displayed spontaneous EPSC frequency approximately twice that of controls, but amplitude was unchanged. Although these changes were not associated with alterations in dendritic spines or in the NMDA/AMPA receptor ratio, they were linked to an increased glutamate release probability from Schaffer collateral, but not temporoammonic pathway. This glutamate increase was associated with reduced activity of presynaptic GABAB receptors and was independent of the endocannabinoid-mediated suppression of excitation. Our new findings demonstrate that early-life inflammation leads to long-term increased hippocampal excitability in adult female and male mice associated with changes in glutamatergic synaptic transmission. These alterations may contribute to enhanced vulnerability of the brain to subsequent pathologic challenges such as epileptic seizures.SIGNIFICANCE STATEMENT Adult physiology has been shown to be affected by early-life inflammation. Our data reveal that early-life inflammation increases excitatory synaptic transmission onto hippocampal CA1 pyramidal neurons in an age-dependent manner through disrupted presynaptic GABAB receptor activity on Schaffer collaterals. This hyperexcitability was seen only in adult, and not in adolescent, animals of either sex. The data suggest a maturation process, independent of sex, in the priming action of early-life inflammation and highlight the importance of studying mature brains to reveal cellular changes associated with early-life interventions.

RESUMEN

BACKGROUND: Question prompt lists (QPLs) are an effective tool for improving communication during medical visits. However, no studies have attempted to correlate intentions related to question asking and actual questions asked during visits. Moreover, few studies have used QPLs with patients with heart failure (HF) or family companions who accompany them to visits. We examined the use of a previsit QPL for patients with HF and their family companions intended to enhance engagement in HF care. The aim of this research was to assess which questions from the QPL patients and companions selected most frequently to ask and compare this item with which questions were actually asked during the medical visit. METHODS AND RESULTS: This secondary analysis of QOLs and audiotaped visit data from a pilot study enrolled and consented patients with HF, family companions, and HF clinicians. A single group of 30 patients with HF and 23 family companions received the QPL to complete in the waiting room immediately before their cardiology visit. To meet our aims, we calculated the frequencies for each question selected and asked from the QPL, using data derived from completed prompt lists and audiotaped medical visits. A follow-up survey was administered 2 days after the appointment to assess differences in how participants filled out and used the prompt list. Patients and companions primarily selected and asked questions from the QPL regarding the management and treatment of the disease, general questions about HF, and questions about prognosis. Participants rarely asked questions about support for family and friends or health care team roles and responsibilities. Patients and companions did not ask many of the questions they reported wanting to ask. CONCLUSIONS: Prompt lists may empower patients and companions to communicate with their clinician by identifying important questions to help overcome patients' and companions' knowledge gaps. More research is needed to understand the true impact of prompt lists on patient-family-clinician communication and subsequent HF outcomes, and how best to implement them in clinical workflows to increase their potential usefulness.

RESUMEN

The global COVID-19 pandemic has imposed restrictions on people's movement, work and access to places at multiple international, national and sub-national scales. We need a better understanding of how the varied restrictions have impacted wildlife monitoring as gaps in data continuity caused by these disruptions may limit future data use and analysis. To assess the effect of different levels of COVID-19 restrictions on both citizen science and traditional wildlife monitoring, we analyse observational records of a widespread and iconic monotreme, the Australian short-beaked echidna (Tachyglossus aculeatus), in three states of Australia. We compare citizen science to observations from biodiversity data repositories across the three states by analysing numbers of observations, coverage in protected areas, and geographic distribution using an index of remoteness and accessibility. We analyse the effect of restriction levels by comparing these data from each restriction level in 2020 with corresponding periods in 2018-2019. Our results indicate that stricter and longer restrictions reduced numbers of scientific observations while citizen science showed few effects, though there is much variation due to differences in restriction levels in each state. Geographic distribution and coverage of protected and non-protected areas were also reduced for scientific monitoring while citizen science observations were little affected. This study shows that citizen science can continue to record accurate and widely distributed species observational data, despite pandemic restrictions, and thus demonstrates the potential value of citizen science to other researchers who require reliable data during periods of disruption.

RESUMEN

BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) is a pediatric complication of severe acute respiratory syndrome coronavirus 2 infection that is characterized by multiorgan inflammation and frequently by cardiovascular dysfunction. It occurs predominantly in otherwise healthy children. We previously reported haploinsufficiency of suppressor of cytokine signaling 1 (SOCS1), a negative regulator of type I and II interferons, as a genetic risk factor for MIS-C. OBJECTIVES: We aimed to identify additional genetic mechanisms underlying susceptibility to severe acute respiratory syndrome coronavirus 2-associated MIS-C. METHODS: In a single-center, prospective cohort study, whole exome sequencing was performed on patients with MIS-C. The impact of candidate variants was tested by using patients' PBMCs obtained at least 7 months after recovery. RESULTS: We enrolled 18 patients with MIS-C (median age = 8 years; interquartile range = 5-12.25 years), of whom 89% had no conditions other than obesity. In 2 boys with no significant infection history, we identified and validated hemizygous deleterious defects in XIAP, encoding X-linked inhibitor of apoptosis, and CYBB, encoding cytochrome b-245, beta subunit. Including the previously reported SOCS1 haploinsufficiency, a genetic diagnosis was identified in 3 of 18 patients (17%). In contrast to patients with mild COVID-19, patients with defects in SOCS1, XIAP, or CYBB exhibit an inflammatory immune cell transcriptome with enrichment of differentially expressed genes in pathways downstream of IL-18, oncostatin M, and nuclear factor κB, even after recovery. CONCLUSIONS: Although inflammatory disorders are rare in the general population, our cohort of patients with MIS-C was enriched for monogenic susceptibility to inflammation. Our results support the use of next-generation sequencing in previously healthy children who develop MIS-C.

RESUMEN

ABSTRACT: Lewis, MH, Siedler, MR, Lamadrid, P, Ford, S, Smith, T, SanFilippo, G, Waddell, B, Trexler, ET, Buckner, S, and Campbell, BI. Sex differences may exist for performance fatigue but not recovery after single-joint upper-body and lower-body resistance exercise. J Strength Cond Res 36(6): 1498-1505, 2022-This study evaluated sex differences in performance recovery and fatigue during dynamic exercise. Twenty-eight resistance-trained males (n = 16) and females (n = 12) completed a repeated-measures, randomized, parallel-groups design. The protocol consisted of a baseline assessment, a recovery period (4, 24, or 48 hours), and a postrecovery assessment. The assessments were identical consisting of 4 sets of 10 repetition maximum (10RM) bicep curls and 4 sets of 10RM leg extensions to failure. Recovery was quantified as the number of total repetitions completed in the postrecovery bout. Fatigue was quantified as the number of repetitions completed set to set within the session. For analysis, we set the level of significance at p ≤ 0.05. No sex differences in performance recovery were observed across any of the investigated time periods for either exercise modality. Regarding fatigue, significant effects were observed for set (p < 0.001) and sex (p = 0.031) for bicep curls. Repetitions dropped in later sets, and females generally completed a greater number of repetitions than males (8.8 ± 0.5 vs. 7.2 ± 0.5). For leg extension, a significant sex × set interaction was observed (p = 0.003), but post hoc tests revealed these sex differences as marginal. Our results suggest that in dynamic bicep curls and leg extensions, other factors unrelated to sex may be more impactful on performance recovery. To optimize an athlete's desired adaptations, it may be more important to consider other variables unrelated to sex such as volume, perceived exertion, and training history when formulating training prescriptions for single-joint exercises.

RESUMEN

BACKGROUND: Sex influences health and related behaviors due to biological and psychosocial/socioeconomic factors. Assessing sex-specific responses to integrated treatment for comorbid obesity and depression could inform intervention targeting. PURPOSE: To test (a) whether sex moderates the effects of integrated collaborative care on weight and depression outcomes through 24 months and (b) whether treatment response at 6 months predicts 12 and 24 month outcomes by sex. METHODS: Secondary data analyses on weight and depression severity (SCL-20) measured over 24 months among 409 adults with obesity and depression in the Research Aimed at Improving Both Mood and Weight trial. RESULTS: Men achieved significantly greater weight reductions in intervention versus usual care than women, whereas women achieved significantly greater percentage reductions in SCL-20 than men at both 12 and 24 months. In logistic models, at 80% specificity for correctly identifying participants not achieving clinically significant long-term outcomes, women who lost <3.0% weight and men who lost <4.1% weight at 6 months had ≥84% probability of not meeting 5% weight loss at 24 months. Similarly, at 80% specificity, women who reduced SCL-20 by <39.5% and men who reduced by <53.0% at 6 months had ≥82% probability of not meeting 50% decrease in SCL-20 at 24 months. CONCLUSIONS: Sex modified the integrated treatment effects for obesity and depression. Sex-specific responses at 6 months predicted clinically significant weight loss and depression outcomes through 24 months. Based on early responses, interventions may need to be tailored to address sex-specific barriers and facilitators to achieving healthy weight and depression outcomes at later time points.

RESUMEN

We used the 1-month pilot implementation of Positive Health Check, a brief web-based video counseling intervention that supports patients with HIV attending HIV primary care clinics, to exemplify how studying implementation strategies earlier in the evidence-generation process can improve implementation outcomes in later pragmatic trials. We identified how implementation strategies were operationalized and the barriers and facilitators these strategies addressed using multiple data sources, including adapted implementation procedures and weekly structured interviews conducted with 9 key stakeholders in 4 HIV primary care clinics. Nineteen of 73 discrete implementation strategies for clinical innovations were used in the pilot implementation of Positive Health Check. Clinic staff reported 17 barriers and facilitators related to the clinic environment, patient population, intervention characteristics, and training and technical assistance. Identifying the link between strategies, barriers, and facilitators helped plan for a subsequent larger multisite pragmatic trial.

RESUMEN

BACKGROUND & AIMS: Eosinophilic esophagitis (EoE) is caused by an immune response to specific food allergens. There are no approved therapies beyond avoidance of the allergen(s) or treatment of inflammation. Epicutaneous immunotherapy (EPIT) reduces features of eosinophilic gastrointestinal disease in mice and pigs. We performed randomized, placebo-controlled study to determine the safety and efficacy of EPIT with Viaskin milk in children with milk-induced EoE. METHODS: In a double-blind study, 20 children (4-17 years old) with milk-induced EoE were randomly assigned to groups given EPIT with Viaskin milk (n = 15) or placebo (n = 5) for 9 months during a milk-free period, followed by milk-containing diet for 2 months with EPIT. Then, subjects underwent upper endoscopy analysis, biopsies were collected, and maximum esophageal eosinophil counts were determined and was the primary endpoint. After upper endoscopy, patients were given open-label EPIT for 11 months (open-label phase). The subjects were allowed to consume milk if they had maximum values of fewer than 10 eosinophils/high-power field (eos/hpf); otherwise, they remained on a milk-free diet until the last 2 months of the open-label phase. RESULTS: In the intent to treat population, there was no significant difference between the Viaskin milk group in mean eos/hpf (50.1 ± 43.97 eos/hpf) vs the placebo group (48.20 ± 56.98 eos/hpf). However, in the per-protocol population (7 patients given Viaskin milk and 2 patients given placebo), patients given Viaskin milk patients had a significantly lower mean eos/hpf count (25.57 ± 31.19) than patients given placebo (95.00 ± 63.64) (p = .038). At the end of the open-label phase, 9 of 19 evaluable subjects had mean values of fewer than 15 eos/hpf (47% response). The number of adverse events did not differ significantly between the Viaskin milk and placebo groups; there was 1 serious adverse event in the placebo group. CONCLUSIONS: In a pilot study of pediatric patients with EoE given EPIT with Viaskin milk or placebo for 11 months, we found no significant difference between groups for the maximum eosinophil count at the end of the study. However, findings from a per-protocol analysis indicate that Viaskin milk can reduce eos/hpf. At study completion, 47% of patients who continued open-label Viaskin milk for an additional 11 months had mean values of fewer than 15 eos/hpf. ClinicalTrials.gov no: NCT02579876.

RESUMEN

OBJECTIVE: This study aimed to understand parental decisions, perspectives, values, and beliefs on next generation sequencing in the newborn period (NGS-NBS) to inform the development of a decision aid to support parental decision making in the North Carolina Newborn Exome Sequencing for Universal Screening study. METHODS: We conducted dyadic interviews with 66 current or expectant parents (33 couples) to understand overall decisions about NGS-NBS and reasons for and against learning NGS-NBS results differing by age of onset and medical actionability. Audio recordings were transcribed, coded, and analyzed using qualitative framework analyses. RESULTS: Favorable views of NGS-NBS included benefits of early intervention, preparedness, child autonomy, and altruism. Unfavorable views were the potential negative effects from early intervention, psychosocial harm, and religious beliefs. Parents universally reported quality of life as important. CONCLUSION: Interviews elucidated what is important in deciding to have NGS-NBS. Understanding parental perspectives, values, and beliefs and integrating evidence-based findings into a parent-centric decision aid provides value and support in making decisions related to NGS-NBS, where there is no clear course of action.

RESUMEN

Childhood maltreatment dysregulates an individual's physiological response to stress, increasing reactivity to stressors across the lifespan. Given the prevalence and impact of bereavement, we examined whether the association between childhood maltreatment and depression was exacerbated by spousal bereavement. We identified an interaction between childhood maltreatment and bereavement using linear regression analysis (B = 0.79, p < .001). A simple slopes test indicated a positive association between childhood maltreatment and depressive symptoms among those who were bereaved (B = 0.86, p < .001), but such association did not emerge among those who were not bereaved (B = 0.06, p = .60).

RESUMEN

PURPOSE: The Clinical Genome Resource (ClinGen) Actionability Working Group (AWG) developed a semiquantitative scoring metric to rate clinical actionability of genetic disorders and associated genes in four domains: (1) severity of the outcome, (2) likelihood of the outcome, (3) effectiveness of the intervention to prevent/minimize the outcome, and (4) nature of the intervention with respect to burden, risk, tolerability, and acceptability to the patient. This study aimed to assess whether nature of the intervention scores assigned by AWG experts reflected lay perceptions of intervention burden, risk, tolerability, and acceptability given the subjectivity of this domain. METHODS: In July 2017, a general population sample of 1344 adults completed the study. Each participant was asked to read 1 of 24 plain language medical intervention synopses and answer questions related to its burden, risk, tolerability, and acceptability. We conducted three multilevel mixed model analyses predicting the perceived burden, perceived risk, and perceived overall nature of the intervention. RESULTS: As AWG nature of the intervention scores increased, lay perceptions of intervention burden and risk decreased, and perceptions of tolerability and acceptability increased. CONCLUSION: The findings show alignment between the ClinGen actionability scoring metric and lay perceptions of the nature of the intervention.

RESUMEN

BACKGROUND: Newborn screening (NBS) occupies a unique space at the intersection of translational science and public health. As the only truly population-based public health program in the United States, NBS offers the promise of making the successes of translational medicine available to every infant with a rare disorder that is difficult to diagnose clinically, but for which strong evidence indicates that presymptomatic treatment will substantially improve outcomes. Realistic NBS policy requires data, but rare disorders face a special challenge: Screening cannot be done without supportive data, but adequate data cannot be collected in the absence of large-scale screening. The magnitude and scale of research to provide this expanse of data require working with public health programs, but most do not have the resources or mandate to conduct research. METHODS: To address this gap, we have established Early Check, a research program in partnership with a state NBS program. Early Check provides the infrastructure needed to identify conditions for which there have been significant advances in treatment potential, but require a large-scale, population-based study to test benefits and risks, demonstrate feasibility, and inform NBS policy. DISCUSSION: Our goal is to prove the benefits of a program that can, when compared with current models, accelerate understanding of diseases and treatments, reduce the time needed to consider inclusion of appropriate conditions in the standard NBS panel, and accelerate future research on new NBS conditions, including clinical trials for investigational interventions.

RESUMEN

Importance: Coexisting obesity and depression exacerbate morbidity and disability, but effective treatments remain elusive. Objective: To test the hypothesis that an integrated collaborative care intervention would significantly improve both obesity and depression at 12 months compared with usual care. Design, Setting, and Participants: The Research Aimed at Improving Both Mood and Weight (RAINBOW) randomized clinical trial enrolled 409 adults with body mass indices (BMIs) of 30 or greater (≥27 for Asian adults) and 9-item Patient Health Questionnaire (PHQ-9) scores of 10 or greater. Primary care patients at a health system in Northern California were recruited from September 30, 2014, to January 12, 2017; the date of final 12-month follow-up was January 17, 2018. Interventions: All participants randomly assigned to the intervention (n = 204) or the usual care control group (n = 205) received medical care from their personal physicians as usual, received information on routine services for obesity and depression at their clinic, and received wireless physical activity trackers. Intervention participants also received a 12-month intervention that integrated a Diabetes Prevention Program-based behavioral weight loss treatment with problem-solving therapy for depression and, if indicated, antidepressant medications. Main Outcomes and Measures: The co-primary outcome measures were BMI and 20-item Depression Symptom Checklist (SCL-20) scores (range, 0 [best] to 4 [worst]) at 12 months. Results: Among 409 participants randomized (mean age of 51.0 years [SD, 12.1 years]; 70% were women; mean BMI of 36.7 [SD, 6.4]; mean PHQ-9 score of 13.8 [SD, 3.1]; and mean SCL-20 score of 1.5 [SD, 0.5]), 344 (84.1%) completed 12-month follow-up. At 12 months, mean BMI declined from 36.7 (SD, 6.9) to 35.9 (SD, 7.1) among intervention participants compared with a change in mean BMI from 36.6 (SD, 5.8) to 36.6 (SD, 6.0) among usual care participants (between-group mean difference, -0.7 [95% CI, -1.1 to -0.2]; P = .01). Mean SCL-20 score declined from 1.5 (SD, 0.5) to 1.1 (SD, 1.0) at 12 months among intervention participants compared with a change in mean SCL-20 score from 1.5 (SD, 0.6) to 1.4 (SD, 1.3) among usual care participants (between-group mean difference, -0.2 [95% CI, -0.4 to 0]; P = .01). There were 47 adverse events or serious adverse events that involved musculoskeletal injuries (27 in the intervention group and 20 in the usual care group). Conclusions and Relevance: Among adults with obesity and depression, a collaborative care intervention integrating behavioral weight loss treatment, problem-solving therapy, and as-needed antidepressant medications significantly improved weight loss and depressive symptoms at 12 months compared with usual care; however, the effect sizes were modest and of uncertain clinical importance.

RESUMEN

PurposeApplication of whole-exome and whole-genome sequencing is likely to increase in clinical practice, public health contexts, and research. We investigated how parental preference for acquiring information from genome-scale testing is influenced by the characteristics of non-medically actionable genetic disorders in children, as well as whether the preferences differed by gender and between African-American and white respondents.MethodsWe conducted a Web-based discrete-choice experiment with 1,289 parents of young children. Participants completed "choice tasks" based on pairs of profiles describing sequencing results for hypothetical genetic disorders, selected the profile in each pair that they believed represented the information that would be more important to know, and answered questions that measured their level of distress.ResultsKnowing the likelihood that the disorder would develop given a true-positive test result was most important to parents. Parents showed greater interest in learning sequencing results for disease profiles with more severe manifestations. This was associated with greater distress. Differences by gender and race reflected small differences in magnitude, but not direction.ConclusionParents preferred to learn results about genetic disorders with more severe manifestations, even when this knowledge was associated with increased distress. These results may help clinicians support parental decision making by revealing which types of sequencing results parents are interested in learning.
