Exploring Social Media Preferences for Healthy Weight Management Interventions Among Adolescents of Color: Mixed Methods Study.

BACKGROUND: Social media holds promise as an intervention platform to engage youths in healthy weight management and target racial inequities in obesity. OBJECTIVE: This mixed methods study aimed to examine social media habits, preferences, and obesity-related behaviors (eg, diet and physical activity) among adolescents of color and understand preferences for healthy weight management interventions delivered via social media. METHODS: This mixed methods study is comprised of a cross-sectional web-based survey and a series of digital focus groups. Study participants (English-speaking youths of color ages 14-18 years) were recruited from high schools and youth-based community settings in Massachusetts and California. For surveys, participants were invited to complete an anonymous web-based survey assessing self-reported sociodemographics, social media habits and preferences, health behaviors (diet, physical activity, sleep, and screen time), and height and weight. For focus groups, participants were invited to participate in 45- to 60-minute web-based group discussions assessing social media habits, preferred social media platforms, and preferences for physical activity and nutrition intervention content and delivery. Survey data were analyzed descriptively; focus group transcripts were analyzed using a directed content analysis approach. RESULTS: A total of 101 adolescents completed the survey and 20 adolescents participated in a total of 3 focus groups. Participants reported most frequently using TikTok, followed by Instagram, Snapchat, and Twitter; preference for platform varied by purpose of use (eg, content consumption, connection, or communication). TikTok emerged as the platform of choice as an engaging way to learn about various topics, including desired health information on physical fitness and diet. CONCLUSIONS: Findings from this study suggest that social media platforms can be an engaging way to reach adolescents of color. Data will inform future social media-based interventions to engage adolescents of color in healthy weight management content.

Parent and Child Preferences and Styles of Communication About Cancer Diagnoses and Treatment.

Communication challenges frequently occur among families and health care providers of children with life-threatening conditions. These obstacles compound concerns related to children's diagnoses and treatment, the family's quality of life, and delivery of care. Developmentally appropriate and validated methods of addressing the communication preferences of families with chronically ill children are limited. This study used six focus groups to determine child and parent preferences and styles of communication centering on new diagnoses and changes in prognosis. Hypothetical situations were used to minimize feelings of self-consciousness among school-aged and adolescent participants. Qualitative analyses (interrater reliability 75%) of child and parent responses revealed 3 categories and 11 subcategories or themes. The category of Characteristics of Communication Exchange included (1) how to tell, (2) who should tell, (3) when to tell, (4) who should be included, and (5) what to tell. The Knowledge and Understanding category included themes of (1) side effects of treatment, (2) what children understand, and (3) questions when being diagnosed. The category of Feelings and Emotions included themes of (1) feelings about changes in prognosis, (2) children's feelings on being informed, and (3) coping and emotional regulation. Results reveal a need for developmentally appropriate, evidence-based education to inform parents on how, what, and when to communicate information concerning their child's disease, as well as instructions around facilitating those discussions. Moreover, a need for professional education and training programs for providers is demonstrated by some parental dissatisfaction with bedside manner and disclosure of information. The data collected from this study lay a foundation for future research in communication as a principal factor in quality of life for pediatric patients and their families.

Chronic ß2AR stimulation limits CFTR activation in human airway epithelia.

Traditional pulmonary therapies for cystic fibrosis (CF) target the downstream effects of CF transmembrane conductance regulator (CFTR) dysfunction (the cause of CF). Use of one such therapy, ß-adrenergic bronchodilators (such as albuterol), is nearly universal for airway clearance. Conversely, novel modulator therapies restore function to select mutant CFTR proteins, offering a disease-modifying treatment. Recent trials of modulators targeting F508del-CFTR, the most common CFTR mutation, suggest that chronic ß-agonist use may undermine clinical modulator benefits. We therefore sought to understand the impact of chronic or excess ß-agonist exposure on CFTR activation in human airway epithelium. The present studies demonstrate a greater than 60% reduction in both wild-type and modulator-corrected F508del-CFTR activation following chronic exposure to short- and long-acting ß-agonists. This reduction was due to reduced cellular generation of cAMP downstream of the ß-2 adrenergic receptor-G protein complex. Our results point towards a posttranscriptional reduction in adenylyl cyclase function as the mechanism of impaired CFTR activation produced by prolonged ß-agonist exposure. ß-Agonist-induced CFTR dysfunction was sufficient to abrogate VX809/VX770 modulation of F508del-CFTR in vitro. Understanding the clinical relevance of our observations is critical for CF patients using these drugs, and for investigators to inform future CFTR modulator drug trials.

Randomized controlled trial of a scoring aid to improve Glasgow Coma Scale scoring by emergency medical services providers.

STUDY OBJECTIVE: Emergency medical services (EMS) personnel frequently use the Glasgow Coma Scale (GCS) to assess injured and critically ill patients. This study assesses the accuracy of EMS providers' GCS scoring, as well as the improvement in GCS score assessment with the use of a scoring aid. METHODS: This randomized, controlled study was conducted in the emergency department (ED) of an urban academic trauma center. Emergency medical technicians or paramedics who transported a patient to the ED were randomly assigned one of 9 written scenarios, either with or without a GCS scoring aid. Scenarios were created by consensus of expert attending emergency medicine, EMS, and neurocritical care physicians, with universal consensus agreement on GCS scores. χ(2) And Student's t tests were used to compare groups. RESULTS: Of 180 participants, 178 completed the study. Overall, 73 of 178 participants (41%) gave a GCS score that matched the expert consensus score. GCS score was correct in 22 of 88 (25%) cases without the scoring aid. GCS was correct in 51 of 90 (57%) cases with the scoring aid. Most (69%) of the total GCS scores fell within 1 point of the expert consensus GCS score. Differences in accuracy were most pronounced in scenarios with a correct GCS score of 12 or below. Subcomponent accuracy was eye 62%, verbal 70%, and motor 51%. CONCLUSION: In this study, 60% of EMS participants provided inaccurate GCS score estimates. Use of a GCS scoring aid improved accuracy of EMS GCS score assessments.
