Feasibility and acceptability of a virtual mindfulness intervention for Black adults with PTSD and depression: Randomized controlled trial.

Mindfulness-based cognitive therapy (MBCT) offers promise as a group-based intervention to alleviate posttraumatic stress disorder (PTSD) and depression symptoms in traumatized Black adults. Given the high level of barriers that exist for low-income Black adults, virtual delivery of MBCT may be helpful. This pilot randomized controlled trial assessed feasibility and acceptability of an adapted 8-week virtual MBCT group intervention for Black adults screening positive for PTSD and depression. Forty-six participants (89.3% women) recruited from an urban safety net hospital were randomized to MBCT or waitlist control (WLC). Overall feasibility was fair (70%); however, completion rates were higher for WLC than MBCT (90% vs. 54%). Group acceptability was high across quantitative and qualitative measures for study completers. Perceived barriers to psychological treatment were high (>9). While showing potential via improved coping skills and positive health changes, this intervention's success hinges on mitigating engagement barriers for future delivery; additional studies are warranted.

Efficacy of social cognition and interaction training in outpatients with schizophrenia spectrum disorders: randomized controlled trial.

Given the relationship between social cognition and functional outcome in schizophrenia, a number of social cognitive interventions have been developed, including Social Cognition Interaction Training (SCIT), a group-based, comprehensive, manualized intervention. In the current trial, we examined SCIT efficacy as well as potential moderators of treatment effects. Fifty-one outpatients were randomized to SCIT or a wait-list-control (WLC), with assessments of social cognition, neurocognition, self-report, symptoms, and functioning conducted at baseline and end of the active phase. Relative to WLC, we did not find significant improvements for SCIT on neurocognition, social cognition, self-report, or symptoms, though there was a trend-level, medium effect favoring the SCIT condition on interpersonal and instrumental role function. Post-hoc analyses indicated that baseline neurocognition did not impact degree of social cognitive or functional change. Shorter duration of illness was significantly associated with better post-training neurocognition and self-esteem and, at trend-level with better symptoms and social functioning. We discuss the importance of outcome measure selection and the need for continued evaluation of potential treatment moderators in order to better match people to existing treatments.

Mindfulness Between the Sheets: Does a Brief Mindfulness Intervention Improve Community-Dwelling Populations' Sexual Experiences and Motivations, and Are Effects Moderated by Attachment Insecurity?

Research is increasingly linking mindfulness with better relationship outcomes. Less clear is whether these benefits extend to the sexual domain or whether the benefits of mindfulness are moderated by individual characteristics. Accordingly, the current report tested whether a brief online mindfulness intervention improved the cognitive, affective, and behavioral aspects of sexual experiences and whether effects varied by attachment anxiety and avoidance. Participants (N = 90) first completed a measure of attachment before reporting their sexual experiences each day for 7-days. Participants then listened to a mindfulness recording every day for 4 weeks. Finally, sexual experiences were reported on every day for 7 days again. Consistent with previous studies, no benefits of the mindfulness intervention were detected for more avoidant persons. Less consistent with expectation, however, the mindfulness intervention did not improve sexual outcomes in general, nor did it buffer other-focused avoidance-based sexual motivations or bolster sexual communal strength among more anxiously attached persons. However, the intervention did increase reports of positive sexuality among more anxious persons. Results are discussed in terms of the differential utility and limits of short mindfulness interventions looking to enhance sexual functioning in different populations and the potential mechanisms behind the presence and absence of effects.

Containing Attachment Concerns: Does Trait Mindfulness Buffer the Links between Attachment Insecurity and Maladaptive Sexual Motivations?

Individuals reporting greater insecure attachment are more likely to report maladaptive sexual motivations, such as sex to avoid negative relational and personal outcomes (e.g., conflict). Despite the costs of such sexual motivations, research is less clear regarding what might buffer the extent to which attachment insecurities manifest in such motives. The current study examined whether trait mindfulness moderates the links between attachment insecurity and maladaptive sexual motives. Participants (N = 194) completed measures of trait mindfulness, general sexual motivations, and attachment. As predicted, the links between attachment anxiety and having sex to cope and affirm the self were eliminated among individuals reporting higher levels of the acting with awareness facet of trait mindfulness. No such buffering effects were seen for attachment avoidance. Instead, acting with awareness mindfulness appeared to increase the extent to which more avoidantly attached individuals reported coping and self-affirmation-based sexual motives. These findings contribute to knowledge regarding the potential utility and limits of mindfulness in relational and sexual contexts, perhaps suggesting that mindfulness may help anxiously attached individuals manage the extent to which attachment concerns manifest in maladaptive sexual motivations. Findings of the study may inform both theory regarding mindfulness in interpersonal functioning and how mindfulness interventions might be deployed in sex therapy contexts.

Primary care-based mindfulness intervention for posttraumatic stress disorder and depression symptoms among Black adults: A pilot feasibility and acceptability randomized controlled trial.

OBJECTIVE: There is support for the use of mindfulness-based approaches with trauma-exposed adults. However, limited data are available on feasibility and acceptability of group-based mindfulness interventions in urban medical clinics serving primarily Black adults with low socioeconomic resources, where rates of trauma exposure are high. The present randomized pilot study evaluated the feasibility and acceptability of an 8-week adapted mindfulness-based cognitive therapy (MBCT) group for trauma-exposed Black adults who screened positive for posttraumatic stress disorder (PTSD) and depression in an urban primary care clinic setting. METHOD: Participants were randomized to waitlist control (WLC) or MBCT. Feasibility and acceptability were assessed through examination of retention rates, measures of group satisfaction and treatment barriers, and qualitative interview. Forty-two Black adults (85% women) were consented; of those, 34 (81%) completed preassessment and randomization. RESULTS: Feasibility of study design was shown, with > 75% (n = 26) of randomized participants completing the study through postassessment. Twenty-four individuals (70.5%) completed through 1-month follow-up. Results showed high levels of group acceptability across quantitative and qualitative measures. Perceived barriers to psychological treatment were high, with an average of > 6 barriers present. CONCLUSIONS: The findings indicate feasibility and acceptability of MBCT group interventions in urban primary care settings with trauma-exposed patients with significant psychopathology. However, substantial barriers to treatment engagement were endorsed and to improve numbers for successful engagement in the intervention, continued efforts to reduce treatment barriers and increase access to mindfulness-based interventions in underresourced communities are needed.

A novel aqueous dimethyl trisulfide formulation is effective at low doses against cyanide toxicity in non-anesthetized mice and rats.

BACKGROUND: Cyanide (CN) is a metabolic poison that is capable of intoxicating individuals through accidental or intentional means. With high concentration exposures, death can occur in minutes. In cases of mass casualty exposures, there is a need for a rapid-acting countermeasure capable of being administered in a short period of time in a pre-hospital setting to treat victims. OBJECTIVE: These studies evaluate the safety and efficacy of a novel aqueous formulation of dimethyl trisulfide (DMTS) as an intramuscular (IM) CN countermeasure using non-anesthetized rodent models. METHODS: Non-anesthetized rodents (mice and rats) were exposed to hydrogen cyanide (HCN) or potassium cyanide (KCN) along with immediate IM 10% DMTS treatment or vehicle treatment. Survival and other parameters, such as the time to recovery and assessment of clinical toxic signs (e.g., gasping, loss of righting reflex, convulsions, etc.), were quantified to determine the effectiveness of 10% DMTS treatment (12.5, 25, 75 mg/kg IM) compared to vehicle control treatment. A rat KCN delayed-treatment model with a 15-minute treatment delay was also utilized to simulate a real-life exposure/treatment scenario with 10% DMTS treatment. The stability of the 10% DMTS formulation was also assessed. RESULTS: A 25 mg/kg IM dose of 10% DMTS exhibits potent efficacy against subcutaneous (SC) KCN challenge in both mice and rats and inhalational HCN exposure in mice. 10% DMTS treatment also shortens the time to recovery in rats using a delayed-treatment model. CONCLUSION: IM treatment with 10% DMTS improves survival and clinical outcomes in non-anesthetized rodent models of acute CN toxicity. Additionally, the use of an SC KCN delayed-treatment model in rats is advised to assess the performance of a candidate CN countermeasure in a more realistic exposure/treatment scenario.

Heart rate variability and HbA1c predict plasma interleukin-6 response to psychosocial stress challenge in trauma-exposed women with type 2 diabetes.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a major public health problem in the United States. Although cardiovascular autonomic functioning, blood glucose control, and inflammation are known to play a role in T2DM, the interaction between these variables remains largely unexplored, particularly in the context of stress. To address this gap, we examined the relationship between these variables in a sample that is uniquely vulnerable to the health consequences of T2DM. METHODS: Participants were 37 trauma-exposed Black women with a diagnosis of T2DM. High frequency heart rate variability (HF-HRV), blood glucose control (HbA1c), and a stressor-evoked biomarker of inflammation (interleukin 6; IL-6) were obtained as part of a larger study of the genetic risk factors for and consequences of trauma exposure. RESULTS: The interaction of HbA1c and HF-HRV was significantly associated with IL-6 response calculated as area under the curve with respect to ground. Post-hoc simple slopes analyses revealed HbA1c, rather than HF-HRV, as the moderator in this association such that higher HF-HRV conferred higher circulating levels of IL-6 only in the presence of lower HbA1c, (ߠ​= â€‹0.60, t â€‹= â€‹3.51, p â€‹= â€‹.001). CONCLUSIONS: Cardiovascular autonomic functioning and blood glucose control were significantly associated with stressor-evoked IL-6 responses when controlling for BMI and age. Moreover, the association between cardiovascular autonomic functioning and inflammation varied at different levels of HbA1c. This highlights the possibility that individuals with trauma exposure and T2DM may benefit from stratification by HbA1c levels for research analysis and treatment decision making.

The mediating role of emotion dysregulation in the association between trait mindfulness and PTSD symptoms among trauma-exposed adults.

OBJECTIVES: Growing evidence of the effectiveness of mindfulness-based interventions for posttraumatic stress disorder (PTSD) warrants greater understanding of factors relevant to the relation between trait mindfulness and PTSD, such as emotion dysregulation (ED). The goal of this study was to examine associations between trait mindfulness, ED, and PTSD symptoms across two samples of trauma-exposed adults. METHODS: Participants for Sample 1 (n = 39, 90% women, 100% Black) and Sample 2 (n = 60, 100% women, 87% Black) were recruited from an urban hospital in the South. Trait mindfulness, ED, and PTSD were assessed. RESULTS: Across both samples, mindfulness and ED were significantly associated with overall PTSD severity (r = -.49 and r = -.42, ps = .001; r = .53 and r = .51, ps < .001, respectively) in the expected direction. In Sample 1, mindful nonjudgment and difficulty with emotion regulation strategies showed the strongest associations with overall PTSD severity as well as symptom clusters. In Sample 2, mindful acceptance and all ED dimensions (except non-awareness) showed strong associations with overall PTSD severity and particularly with negative cognitions and mood symptoms. In both samples, ED mediated the association between mindfulness and overall PTSD severity (Sample 1: ab = -.15, 95%CI [-.35, -.02]; Sample 2: ab = -.11, 95%CI [-.22, -.04]). CONCLUSIONS: These findings demonstrate the important role of ED in the relation between trait mindfulness and PTSD symptoms among trauma-exposed adults. They highlight the value of examining ED as a mechanism of change in mindfulness-based interventions for PTSD. CLINICAL TRIALS REGISTRATION INFORMATION: Sample 1: NCT03922581, April 22, 2019; NCT03938350, May 6, 2019; Sample 2: NCT02754557, April 28, 2016.

Emotion dysregulation and dissociation contribute to decreased heart rate variability to an acute psychosocial stressor in trauma-exposed Black women.

Reduced heart rate variability (HRV) in response to stress is a biomarker of emotion dysregulation (ED) and is related to posttraumatic stress disorder (PTSD), yet less is known about its role with dissociation in trauma-exposed adults. The goals of the current study were to examine unique patterns of associations between ED, dissociation, and PTSD with HRV at 15, 30, and 45 min (T1, T2, T3) following an acute psychosocial stressor task in a sample of 49 trauma-exposed, urban-dwelling Black women. Associations with baseline psychophysiology measures were also examined. ED and dissociation were assessed using self-report; PTSD was determined using a semi-structured interview. Heart rate (HR) and HRV, indexed with low frequency/high frequency (LF/HF) ratio and respiratory sinus arrhythmia (RSA), were measured with electrocardiogram recordings. ED and dissociation were positively correlated with LF/HF ratio at T3 (p < .05). There were no significant differences between individuals with PTSD versus those without PTSD in HR or HRV following acute stressor; PTSD diagnosis was related to higher HR at baseline. Latent growth modeling revealed that ED was associated with higher LF/HF ratio directly following acute stressor, while dissociation was associated with increase in LF/HF ratio over time. These findings demonstrate that ED is related to higher sympathetic reactivity for a prolonged period of time following stress exposure, while dissociation shows a delayed association with LF/HF ratio, suggesting a distinct impaired parasympathetic activation pattern exists for dissociation.

Characterizing Typologies of Polytraumatization: A Replication and Extension Study Examining Internalizing and Externalizing Psychopathology in an Urban Population.

A person-centered approach to examining trauma has uncovered typologies of polytraumatization that are differentially associated with psychopathology. However, previous research is limited by narrow conceptualizations of trauma, limited distal outcomes, and underrepresentation of minorities. To address these gaps, we used latent profile analyses to uncover distinct polytraumatization typologies and examine four symptom-based (PTSD, depression, aggression, and substance abuse) and two behavior-based (self-harm, jail counts) outcomes in a sample of low-income adults (n = 7,426, 94% African American). The models were indicated by 19 traumatic experiences (e.g., accident, sexual assault, witnessing/experiencing violence). The best fitting model uncovered five classes: minimal trauma, physical abuse, violence exposure, sexual abuse, and polytrauma. Classes characterized by significant and varied trauma were higher on both internalizing and externalizing psychopathology, while those characterized by specific types of trauma were only higher on one type of psychopathology. Implications for the assessment and treatment of trauma-related disorders are discussed.

Racial discrimination and posttraumatic stress: examining emotion dysregulation as a mediator in an African American community sample.

Background: African Americans experience more severe and chronic posttraumatic stress disorder (PTSD) symptoms compared to other racial groups, and thus it is important to examine factors that are relevant for the aetiology of PTSD in this population. Although racial discrimination has been implicated as an exacerbating factor in the development and maintenance of PTSD, relatively less is known about mechanisms through which this process may occur. Objective: The purpose of this study was to examine one such mechanism, emotion dysregulation, in two independent samples of African American adults. Method: Trauma-exposed participants were recruited in a large, urban community hospital setting (initial sample n = 1,841; replication sample n = 294). In the initial sample, participants completed a unidimensional measure of emotion dysregulation and self-reported PTSD symptoms based on the DSM-IV. In the replication sample, participants completed a multidimensional measure of emotion dysregulation and a diagnostic interview of PTSD symptoms based on the DSM-5. Mediation analyses were used to test our hypotheses. Results: Across both samples, results indicated that racial discrimination was indirectly associated with PTSD symptoms through emotion dysregulation (even when trauma load was added as a covariate). Conclusions: Taken together, these results provide strong evidence that the association between racial discrimination and PTSD symptoms may be partially explained by the association between racial discrimination and worse emotion dysregulation. These findings elucidate the impact of racist incidents on mental health and identify modifiable emotion regulatory processes that can be intervened upon to enhance the psychological and social wellbeing of African Americans.

Antecedentes: Los afroamericanos experimentan síntomas de trastorno de estrés postraumático (TEPT) en forma más severa y crónica en comparación con otros grupos raciales y, por lo tanto, es importante examinar los factores que son relevantes para la etiología del TEPT en esta población. Aunque la discriminación racial ha sido implicada como un factor agravante en el desarrollo y mantenimiento del TEPT, se sabe relativamente poco acerca de los mecanismos por los cuales este proceso puede ocurrir.Objetivo: El propósito de este estudio fue examinar uno de tales mecanismos, la desregulación emocional, en dos muestras independientes de adultos afroamericanos.Método: Los participantes expuestos a trauma fueron reclutados en un gran hospital comunitario urbano (Muestra 1 n= 1.841; Muestra 2 n= 294).Todos los participantes completaron una medida de discriminación racial, pero para la muestra 1, los participantes completaron una medida unidimensional de desregulación emocional y síntomas de TEPT auto-informados y para la Muestra 2, los participantes completaron una medida multidimensional de desregulación emocional y una entrevista diagnostica de síntomas de TEPT. Para probar nuestra hipótesis se utilizaron análisis de mediación.Resultados: En ambas muestras, los resultados indicaron que la discriminación racial estuvo asociada indirectamente con síntomas de TEPT a través de la desregulación emocional (incluso cuando la carga del trauma se agregó como una covariable).Conclusiones: En conjunto, estos resultados proveen una fuerte evidencia que la asociación entre discriminación racial y síntomas de TEPT puede explicarse en parte por la asociación entre discriminación racial y una peor desregulación emocional. Estos hallazgos dilucidan el impacto de los incidentes racistas en la salud mental e identifican procesos reguladores de emociones modificables que pueden intervenirse para mejorar el bienestar psicológico y social de los afroamericanos.

Trauma exposure and stress-related disorders in African-American women with diabetes mellitus.

OBJECTIVE: The purpose of the study was to assess demographic features, rates of trauma exposure, prevalence of post-traumatic stress and depressive symptoms in a group of urban, low-income, African-American women with type 1 or type 2 diabetes mellitus. RESEARCH DESIGN AND METHODS: We conducted a survey of (n = 290) low-income, African-American women seeking care in the diabetes clinic of an urban hospital and collected data on the demographic characteristics, childhood and nonchildhood abuse trauma exposure, and the severity of post-traumatic stress and depressive symptoms using the Post-traumatic Stress Disorder (PTSD) Symptom Scale (PSS) and the Beck Depression Inventory (BDI). In a subset of women with type 2 diabetes (n = 96), we assessed haemoglobin A1c to examine the relationship between psychopathology and glycaemic control. RESULTS: Of the overall sample, 61.7% reported exposure to trauma in their lifetime, and 30.4% and 29.3% had current PTSD and MDD, respectively. Exposure to both childhood and nonchildhood abuse trauma was associated with an increased PTSD and depressive symptom severity (P's < .05). PTSD diagnosis, but not depression, was associated with increased haemoglobin A1c (P = .002). CONCLUSIONS: These data document high levels of trauma exposure, PTSD and depressive symptoms in diabetic African-American women treated in a specialty clinic of an urban hospital setting. Furthermore, these data indicate that the presence of PTSD is negatively associated with glycaemic control.

The Effectiveness of Topical Cannabidiol Oil in Symptomatic Relief of Peripheral Neuropathy of the Lower Extremities.

BACKGROUND: Peripheral neuropathy can significantly impact the quality of life for those who are affected, as therapies from the current treatment algorithm often fail to deliver adequate symptom relief. There has, however, been an increasing body of evidence for the use of cannabinoids in the treatment of chronic, noncancer pain. The efficacy of a topically delivered cannabidiol (CBD) oil in the management of neuropathic pain was examined in this four-week, randomized and placebocontrolled trial. METHODS: In total, 29 patients with symptomatic peripheral neuropathy were recruited and enrolled. 15 patients were randomized to the CBD group with the treatment product containing 250 mg CBD/3 fl. oz, and 14 patients were randomized to the placebo group. After four weeks, the placebo group was allowed to crossover into the treatment group. The Neuropathic Pain Scale (NPS) was administered biweekly to assess the mean change from baseline to the end of the treatment period. RESULTS: The study population included 62.1% males and 37.9% females with a mean age of 68 years. There was a statistically significant reduction in intense pain, sharp pain, cold and itchy sensations in the CBD group when compared to the placebo group. No adverse events were reported in this study. CONCLUSION: Our findings demonstrate that the transdermal application of CBD oil can achieve significant improvement in pain and other disturbing sensations in patients with peripheral neuropathy. The treatment product was well tolerated and may provide a more effective alternative compared to other current therapies in the treatment of peripheral neuropathy.

Indoor versus Outdoor Air Quality during Wildfires.

The human behavioral modification recommendations during wildfire events are based on particulate matter and may be confounded by the potential risks of gas-phase pollutants such as polycyclic aromatic hydrocarbons (PAHs). Moreover, the majority of adults spend over 90 percent of their time indoors where there is an increased concern of indoor air quality during wildfire events. We address these timely concerns by evaluating paired indoor and outdoor PAH concentrations in residential locations and their relationship with satellite model-based categorization of wildfire smoke intensity. Low-density polyethylene passive air samplers were deployed at six urban sites for 1 week in Eugene, Oregon with matched indoor and outdoor samples and 24 h time resolution. Samples were then quantitatively analyzed for 63 PAH concentrations using gas-chromatography-tandem mass spectrometry. A probabilistic principal components analysis was used to reduce all 63 PAHs into an aggregate measure. Linear regression of the first principal component against indoor versus outdoor shows that indoor gas-phase PAH concentrations are consistently equal to or greater than outdoor concentrations. Regression against a satellite-based model for wildfire smoke shows that outdoor, but not indoor gas-phase PAH concentrations are likely associated with wildfire events. These results point toward the need to include gas-phase pollutants such as PAHs in air pollution risk assessment.

The Effect of a Common Antibiotics Doxycycline on Non-Healing Chronic Wound.

BACKGROUND: Up to 25% of diabetic patients will develop a diabetic foot ulcer. Chronic wounds such as diabetic foot ulcers often fail to heal with conventional therapies. In recent years, it has been identified that chronic wounds are usually associated with elevated level of matrix metalloproteinases (MMPs). Doxycycline, a cheap tetracycline antibiotic, has been shown to inhibit MMPs both in vitro and in vivo independent of its antimicrobial property. METHODS: We undertook a search through PUBMED for peer-reviewed research literature with doxycycline, chronic wound, diabetes, MMPs as key words. RESULTS: Seventy papers were included in the review. This review identified doxycycline is a very promising drug to be used in patients with diabetic foot ulcers because higher efficacy even in a very low dosage, little side effects in a lower dosage, inhibition of MMP as well as prevention/treatment of infection in the ulcers, beneficial to cardiovascular complications and cheap to manufacture. CONCLUSION: In this review, we provide an overview of the roles of MMPs in the pathogenesis of chronic wounds and explore the potential application of doxycycline as a treatment option in managing chronic wounds such as diabetic foot ulcers.

Unveil the mysterious mask of cytokine-based immunotherapy for melanoma.

Melanoma is the leading cause of death among all skin cancers and its incidence continues to rise rapidly worldwide in the past decades. The available treatment options for melanoma remain limited despite extensive clinical research. Melanoma is an immunogenic tumor and great advances in immunology in recent decades allow for the development of immunotherapeutic agents against melanoma. In recent years, immunotherapy utilizing cytokines has been particularly successful in certain cancers and holds promise for patients with advanced melanoma. In this review, an overview of the current status and emerging perspectives on cytokine immunotherapy for melanoma are discussed in details. Such a study will be helpful to unveil the mysterious mask of cytokine-based immunotherapy for melanoma.

Population-based evaluation of the 'LiveLighter' healthy weight and lifestyle mass media campaign.

The Western Australian (WA) 'LiveLighter' (LL) mass media campaign ran during June-August and September-October 2012. The principal campaign ad graphically depicts visceral fat of an overweight individual ('why' change message), whereas supporting ads demonstrate simple changes to increase activity and eat healthier ('how' to change message). Cross-sectional surveys among population samples aged 25-49 were undertaken pre-campaign (N= 2012) and following the two media waves (N= 2005 and N= 2009) in the intervention (WA) and comparison state (Victoria) to estimate the population impact of LL. Campaign awareness was 54% after the first media wave and overweight adults were more likely to recall LL and perceive it as personally relevant. Recall was also higher among parents, but equal between socio-economic groups. The 'why' message about health-harms of overweight rated higher than 'how' messages about lifestyle change, on perceived message effectiveness which is predictive of health-related intention and behaviour change. State-by-time interactions showed population-level increases in self-referent thoughts about the health-harms of overweight (P < 0.05) and physical activity intentions (P < 0.05). Endorsement of stereotypes of overweight individuals did not increase after LL aired. LL was associated with some population-level improvements in proximal and intermediate markers of campaign impact. However, sustained campaign activity will be needed to impact behaviour.

The role of IL-11 in immunity and cancer.

Interleukin-11 (IL-11) is a member of the glycoprotein-130 (GP-130) cytokines that utilizes the GP-130 signaling pathway shared by other cytokines of the same family. Traditionally regarded as an anti-inflammatory cytokine, IL-11 also demonstrates its role as a proinflammatory cytokine, suggesting its complex role in immune response. In recent years, IL-11 has an emerging role in various inflammation-associated cancers. In this review, we aim to discuss IL-11 signaling pathway, to explore the role of IL-11 in immunity and various cancers, and to provide a therapeutic perspective of strategies utilized to interfere IL-11 signaling in cancer cells.

Effects of nutrient content claims, sports celebrity endorsements and premium offers on pre-adolescent children's food preferences: experimental research.

OBJECTIVES: To assess pre-adolescent children's responses to common child-oriented front-of-pack food promotions. METHODS: Between-subjects, web-based experiment with four front-of-pack promotion conditions on energy-dense and nutrient-poor (EDNP) foods: no promotion [control]; nutrient content claims; sports celebrity endorsements (male athletes) and premium offers. Participants were 1302 grade 5 and 6 children (mean age 11 years) from Melbourne, Australia. Participants chose their preferred product from a randomly assigned EDNP food pack and comparable healthier food pack then completed detailed product ratings. Child-oriented pack designs with colourful, cartooned graphics, fonts and promotions were used. RESULTS: Compared to the control condition, children were more likely to choose EDNP products featuring nutrient content claims (both genders) and sports celebrity endorsements (boys only). Perceptions of nutritional content were enhanced by nutrient content claims. Effects of promotions on some product ratings (but not choice) were negated when children referred to the nutrition information panel. Premium offers did not enhance children's product ratings or choice. CONCLUSIONS: Nutrient content claims and sports celebrity endorsements influence pre-adolescent children's preferences towards EDNP food products displaying them. Policy interventions to reduce the impact of unhealthy food marketing to children should limit the use of these promotions.
