Early life Western diet-induced memory impairments and gut microbiome changes in female rats are long-lasting despite healthy dietary intervention.

OBJECTIVE: Western diet consumption during adolescence results in hippocampus (HPC)-dependent memory impairments and gut microbiome dysbiosis. Whether these adverse outcomes persist in adulthood following healthy dietary intervention is unknown. Here we assessed the short- and long-term effects of adolescent consumption of a Western diet enriched with either sugar or both sugar and fat on metabolic outcomes, HPC function, and gut microbiota. METHODS: Adolescent female rats (PN 26) were fed a standard chow diet (CHOW), chow with access to 11% sugar solution (SUG), or a junk food cafeteria-style diet (CAF) containing various foods high in fat and/or sugar. During adulthood (PN 65+), metabolic outcomes, HPC-dependent memory, and gut microbial populations were evaluated. In a subsequent experiment, these outcomes were evaluated following a 5-week dietary intervention where CAF and SUG groups were maintained on standard chow alone. RESULTS: Both CAF and SUG groups demonstrated impaired HPC-dependent memory, increased adiposity, and altered gut microbial populations relative to the CHOW group. However, impaired peripheral glucose regulation was only observed in the SUG group. When examined following a healthy dietary intervention in a separate experiment, metabolic dysfunction was not observed in either the CAF or SUG group, whereas HPC-dependent memory impairments were observed in the CAF but not the SUG group. In both groups the composition of the gut microbiota remained distinct from CHOW rats after the dietary intervention. CONCLUSIONS: While the metabolic impairments associated with adolescent junk food diet consumption are not present in adulthood following dietary intervention, the HPC-dependent memory impairments and the gut microbiome dysbiosis persist.

Information Sharing in Neurosurgery Topics Among Pediatric Patients and Loved Ones Within the Reddit Community.

Introduction With crowd-sourced knowledge, patients arrive at their healthcare visits ready to play an active role. This exploratory study seeks to understand common concerns among patients and loved ones on Reddit, an anonymous internet forum. Ultimately, recognizing common concerns can aid providers in directing their conversations with patients. Methods Reddit posts in the "hot" tab of each subreddit were retroactively screened from September 1, 2022. Posts written within a five-year period were included. Posts by pediatric patients, loved ones, and pregnant patients experiencing the condition or whose fetus was diagnosed were included. Posts omitting the poster's age or individuals, outside of loved ones, who self-identified as over the age of 17 were excluded. Results A total of 12 subreddits and 286 posts were identified, with 37% of posts written by patients and 63% of posts written by a loved one. R/scoliosis patients (n=29) and r/epilepsy loved ones (n=28) sought the most health advice. The subreddit r/hydrocephalus comprised the most post-operative treatment symptom questions. The r/cerebralpalsy subreddit sought the most advice related to daily activities. Discussion Patients within r/scoliosis, r/hydrocephalus, and r/epilepsy are asking health-related questions. Hydrocephalus patients utilize anonymous internet responses to prepare for upcoming healthcare visits. Individuals in r/cerebralpalsy are utilizing Reddit as a method of communication; understanding how these patients interact with social media can guide software development tailored for online interactions. The anonymity of Reddit prevents us from understanding the diversity of posters. Conclusion Reddit is an avenue to disseminate correct information to pediatric patients and loved ones. Healthcare providers can use the information gathered to tailor their discussions better.

Your Brain on Reddit: Exploring Neurosurgical Concerns on a Popular Social Media Site.

OBJECTIVE: Social media has irreversibly impacted global interpersonal connectivity. This study aims to understand how information discussed in condition-specific communities, called "subreddits," on the major social media platform Reddit, can improve education by medical providers. METHODS: The top 50 Reddit posts in each subreddit's "hot" tab were retroactively screened from June 1, 2022. Posts written by those 18 and older who had the condition or were engaging in a better understanding of the condition were included in the analysis. In addition, posts were placed in 1 of 6 categories based on the redditors' primary questions: social advice, health advice, providing health education or suggesting equipment, personal experience/progress, researchers recruiting patients for research, or others. RESULTS: We identified 605 posts within 15 subreddits related to cranial neurosurgical topics including epilepsy, traumatic brain injury, stroke, brain tumors/cancer, seizures, hydrocephalus, cerebrospinal fluid leaks, Chiari malformations, aneurysms, pineal cysts, ataxia, and moyamoya. Asking for health advice was the most common form of information seeking across subreddits (53.6%), specifically treatment-related questions (41.0%). Redditors from r/epilepsy and r/seizures constituted 84.6% of nonsurgical treatment questions relating to antiepileptic dosing or side effects. CONCLUSIONS: Cranial neurosurgical disease can overwhelm patients, leaving them with unaddressed questions. Reddit provides anonymity and camaraderie within condition-specific communities not found at the doctor's office. The ease of access to an Internet community may encourage redditors to seek health information online.
