Abstract
This paper investigated cortical thickness and volumetric changes in children to better understand the impact of obstructive sleep disordered breathing (SDB) on the neurodevelopment of specific regions of the brain. We also aimed to investigate how these changes were related to the behavioral and cognitive deficits observed in the condition. Neuroimaging, behavioral, and sleep data were obtained from 30 children (15 non-snoring controls, 15 referred for assessment of SDB) aged 7 to 17 years. Gyral-based regions of interest were identified using the Desikan-Killiany atlas. Student's t-tests were used to compare regions of interest between the controls and SDB groups. We found that the cortical thickness was significantly greater in the right caudal anterior cingulate and right cuneus regions and there were volumetric increases in the left caudal middle frontal, bilateral rostral anterior cingulate, left, right, and bilateral caudate brain regions in children with SDB compared with controls. Neither cortical thickness nor volumetric changes were associated with behavioral or cognitive measures. The findings of this study indicate disruptions to neural developmental processes occurring in structural regions of the brain; however, these changes appear unrelated to behavioural or cognitive outcomes.

Learning and memory impairment and transcriptomic profile in hippocampus of offspring after maternal fructose exposure during gestation and lactation. Food Chem Toxicol 2022; 169:113394. [PMID: 36049592 DOI: 10.1016/j.fct.2022.113394] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 08/06/2022] [Accepted: 08/24/2022] [Indexed: 11/22/2022]
Abstract
Increased fructose intake is a global issue, especially in mothers. Maternal fructose exposure during gestation and lactation can affect learning and memory in offspring; however, the detailed mechanism is still unknown. The hippocampus is a mind locale liable for learning and memory. Here, we established a maternal high-fructose diet model by administering 13% and 40% fructose water, applied the Morris Water Maze test on postnatal day 60 offspring, and performed full-length RNA sequencing using the Oxford Nanopore Technologies platform to explore the changes in gene expression in the hippocampus. The results showed that learning and memory in offspring were negatively affected. Compared with the control group, 369 differentially expressed transcripts (DETs) were identified in the 13% fructose group, and 501 DETs were identified in the 40% fructose group. Gene Ontology enriched term and Kyoto Encyclopedia of Genes and Genomes enriched pathway analyses identified several terms and pathways related to brain development and cognitive function. Furthermore, we confirmed that the Wnt/β-catenin signaling pathway was down-regulated and neuron degeneration was enhanced. In summary, our results indicate that maternal fructose exposure during gestation and lactation can impair learning and memory in offspring and affect brain function at the transcriptome level.

Abstract
This review provides an update on the neurocognitive phenotype of pediatric obstructive sleep apnea (OSA). Pediatric OSA is associated with neurocognitive deficits involving memory, learning, and executive functioning. Adenotonsillectomy (AT) is presently accepted as the first-line surgical treatment for pediatric OSA, but the executive function deficits do not resolve postsurgery, and the timeline for recovery remains unknown. This finding suggests that pediatric OSA potentially causes irreversible damage to multiple areas of the brain. The focus of this review is the hippocampus, 1 of the 2 major sites of postnatal neurogenesis, where new neurons are formed and integrated into existing circuitry and the mammalian center of learning/memory functions. Here, we review the clinical phenotype of pediatric OSA, and then discuss existing studies of OSA on different cell types in the hippocampus during critical periods of development. This will set the stage for future study using preclinical models to understand the pathogenesis of persistent neurocognitive dysfunction in pediatric OSA.

Abstract
BACKGROUND AND OBJECTIVES Extensive evidence links smoking and suicide independently of psychiatric diagnoses, but there are questions about the pathophysiology and specificity of this relationship. We examined characteristics of this linkage to identify potential transdiagnostic mechanisms in suicide and its prevention. METHODS We reviewed literature that associated suicide with smoking and e-cigarettes, including the temporal sequence of smoking and suicide risk and their shared behavioral risk factors of sensitization and impulsivity. RESULTS Smoking is associated with increased suicide across psychiatric diagnoses and in the general population, proportionately to the number of cigarettes smoked per day. Rapid nicotine uptake into the brain through inhalation of conventional cigarettes, electronic cigarettes (e-cigarette), or even second-hand smoke can facilitate long-term sensitization and short-term impulsivity. Both impair action regulation and predispose to negative affect, continued smoking, and suicidal behavior. Intermittent hypoxia, induced by cigarettes or e-cigarettes, synergistically promotes impulsivity and sensitization, exacerbating suicidality. Two other shared behavioral risks also develop negative urgency (combined impulsivity and negative affect) and cross-sensitization to stressors or to other addictive stimuli. Finally, early smoking onset, promoted by e-cigarettes in never-smokers, increases subsequent suicide risk. CONCLUSION AND SCIENTIFIC SIGNIFICANCE Prevention or cessation of nicotine inhalation can strategically prevent suicidality and other potentially lethal behavior regardless of psychiatric diagnoses. Medications for reducing smoking and suicidality, especially in younger smokers, should consider the neurobehavioral mechanisms for acute impulsivity and longer-term sensitization, potentially modulated more effectively through glutamate antagonism rather than nicotine substitution.

Abstract
OBJECTIVE To determine whether a postoperative prescription for opioids affects parental assessment of pain control following pediatric circumcision. METHODS This postoperative survey assessed the parental assessment of pain control in 199 patients, ages<18 years undergoing circumcision. This study was conducted at a quaternary care children's hospital in Houston, Texas from December 2018 to January 2020. Postoperative pain regimens included acetaminophen and ibuprofen or combination hydrocodone/acetaminophen in addition to ibuprofen for postoperative analgesia based on the surgical preference. The primary study outcome was identification of the proportion of parents rating their child's analgesia following pediatric circumcision as poor or inadequate based on the postoperative analgesic regimen. RESULTS Of the 502 surveys sent, the response rate was 40% (199/502) of those who received the survey email, and 64% (199/308) for those who opened the email. Between the opioid and nonopioid groups, there was no difference in, race/ethnicity (Caucasian; 28% vs 37%; P = .43) or insurance status (insured; 51% vs 45%; P = .44). The proportion of parents who rated their child's pain as poor or inadequately controlled following circumcision was relatively rare:5.5% and 1.1% in the nonopioid and opioid groups, respectively. Parents rating their child's pain as excellent with regards to pain control following circumcision were 61% and 53% in the nonopioids and opioid groups, respectively. CONCLUSION The results of this study indicate that nonopioid analgesic regimens following pediatric circumcision were not associated with decreased parental satisfaction or an increasing assessment of poor or inadequately controlled pain. Limiting opioid exposure following pediatric circumcision is feasible and does not result in worse parental satisfaction with the analgesic plan.

Abstract
OBJECTIVES Pediatric Obstructive Sleep Apnea (OSA) is associated with neurocognitive deficits. Cerebral structural alterations in the frontal cortex, cerebellum, and hippocampus have been reported in adult OSA patients. These brain areas are important for executive functioning, motor regulation of breathing, and memory function, respectively. Corresponding evidence comparing cerebral structures in pediatric OSA patients is limited. The objective of this study is to investigate MRI differences in cortical thickness and cortical volume in children with and without OSA. STUDY DESIGN Prospective, single institutional case-control study. METHODS Forty-five children were recruited at a pediatric tertiary care center (27 with OSA; mean age 9.9 ± 1.9 years, and 18 controls; mean age 10.5 ± 1.0 years). The OSA group underwent magnetic resonance imaging (MRI), polysomnography (PSG) and completed the Pediatric Daytime Sleepiness Scale (PDSS) and the Child's Sleep Habits Questionnaire (CSHQ). High-resolution T1-weighted MRI was utilized to examine cortical thickness and gray and white matter volume in children with OSA compared to a healthy group of demographically-comparable children without OSA selected from a pre-existing MRI dataset. RESULTS Children with OSA showed multiple regions of cortical thinning primarily in the left hemisphere. Reduced gray matter (GM) volume was noted in the OSA group in multiple frontal regions of the left hemisphere (superior frontal, rostral medial frontal, and caudal medial frontal regions). Reduced white matter (WM) volume in both the left and right hemisphere was observed in regions of the frontal, parietal, and occipital lobes in children with OSA. CONCLUSION This study noted differences in cortical thickness and GM and WM regional brain volumes in children with OSA. These findings are consistent with other pediatric studies, which also report differences between healthy children and those with OSA. We found that the severity of OSA does not correlate with the extent of MRI alterations.

Abstract
Pediatric obstructive sleep apnea affects a large number of children and has multiple end-organ sequelae. Although many of these have been demonstrated to be reversible, the effects on some of the organ systems, including the brain, have not shown easy reversibility. Progress in this area has been hampered by lack of a preclinical model to study the disease. Therefore, perioperative and sleep physicians are tasked with making a number of difficult decisions, including optimal surgical timing to prevent disease evolution, but also to keep the perioperative morbidity in a safe range for these patients.

Abstract
INTRODUCTION Postoperative prescribing of opioids following pediatric adenotonsillectomy can have negative consequences including unnecessary opioid exposure and potential for respiratory depression. While guidelines from The American Academy of Otolaryngology/Head & Neck Surgery recommend treatment of post adenotonsillectomy pain using acetaminophen and ibuprofen, many providers continue to prescribe opioids and may do so, in part with concern for parental dissatisfaction with post-operative analgesia. Our aim was to determine whether a post-operative prescription for opioids affects parental assessment of pain control following pediatric adenotonsillectomy. METHODS This post-operative survey assessed the parental assessment of pain control in 324 patients, ages 1-17 years undergoing adenotonsillectomy. This study was conducted at a quaternary care children's hospital in Houston, Texas from December 1, 2018 through March 31, 2019. Post-operative pain regimens included acetaminophen and ibuprofen or combination hydrocodone/acetaminophen in addition to ibuprofen for post-operative analgesia based on the attending surgeons prescribing preferences. The primary study outcome was identification of the proportion of parents rating their child's analgesia following pediatric adenotonsillectomy as poor or inadequate based on the post-operative analgesic regimen including opioids. RESULTS Of the 798 surveys sent, the response rate was 42% (324/775) of those who received the survey email, and 69% (324/470) for those who opened the email. Between the opioid and non-opioid groups, there was no difference in gender (male; 48% vs. 51.3%; p = 0.58), race/ethnicity (white; 53% vs. 46%; p = 0.35) or insurance status (insured; 62% vs. 50.9%; p = 0.06). The proportion of parents who rated their child's pain as poor or inadequately controlled following adenotonsillectomy was relatively rare: 9% and 5% in the non-opioid and opioid groups, respectively. Parents rating their child's pain as excellent with regards to pain control following adenotonsillectomy were 58% and 50% in the non-opioids and opioid groups respectively. CONCLUSION The results of this study indicate that non-opioid analgesic regimens following pediatric adenotonsillectomy were not associated with decreased parental satisfaction or an increasing assessment of poor or inadequately controlled pain. Limiting opioid exposure following pediatric adenotonsillectomy is feasible and does not result in worse parental satisfaction with the analgesic plan.

Abstract
Obstructive sleep apnea (OSA) affects up to 7.5% of the pediatric population and is associated with a variety of behavioral and neurocognitive sequelae. Prompt diagnosis and treatment is critical to halting and potentially reversing these changes. Depending on the severity of the OSA and comorbid conditions, different treatment paradigms can be pursued, each of which has its own unique risk:benefit ratio. Adenotonsillectomy is first-line recommended surgical treatment for pediatric OSA. However, it carries its own perioperative risks and the decision regarding surgical timing is therefore made in the context of procedural risk versus patient benefit. This article presents the seminal perioperative and neurocognitive risks from pediatric OSA to aid with perioperative management.
