Objectives Methods Results Conclusions Oral health is an important part of general health and well‐being and shares risk factors, such as poor diet, with obesity. The published literature assessing the association between obesity and oral health in early childhood is sparse and inconsistent. The objective of this study was to investigate associations between overweight/obesity (measured by body mass index) and dental outcomes (caries, plaque index and gingival index) both cross‐sectionally and longitudinally, taking account of potential confounding factors, based on data collected at age 2 and age 5 within the Australian Study of Mothers' and Infants' Life Events Affecting Oral Health (SMILE) birth cohort study.This study used data from 1174 SMILE participants. Associations between overweight/obesity and dental outcomes were assessed using generalized linear regression models for the modified Poisson family with log link to estimate prevalence ratios. Cross‐sectional and longitudinal models were fitted, after minimal and full adjustment for potential confounders.Approximately 12% of the participants were overweight/obese at 2 years and 9% at 5 years. Between 2 and 5 years, the prevalence of caries increased from approximately 4% to 24%, at least mild plaque accumulation increased from 37% to 90% and at least mild inflammation from 27% to 68%. There were no associations between overweight/obesity and the prevalence of dental caries; prevalence ratios (PR) [95% confidence interval (CI)] after adjustment for age and sex were 0.9 (0.3, 2.4) cross‐sectionally at 2 years, 1.0 (0.6, 1.5) cross‐sectionally at 5 years, and 1.0 (0.6, 1.5) for overweight/obesity at 2 years and caries at 5 years. Prevalence ratios were all around the value of 1 for the other dental outcomes and also after adjustment for additional confounders.There were no associations between overweight/obesity and dental caries, plaque index or gingival index in this cohort of preschool children. However, associations may emerge as the children become older, and it will be possible to extend analyses to include data collected at age 7 in the near future. [ABSTRACT FROM AUTHOR]

Encephalocraniocutaneous lipomatosis (ECCL) is a rare genetic condition with well-described skin, ocular, and central nervous system findings. Several case reports have been documented demonstrating the presence of low-grade gliomas in patients with ECCL and the association with certain FGFR1 mutations. We report on a case of diffuse low-grade glioma, mitogen activated protein kinase pathway altered in a patient with ECCL, who was found to have a distinct FGFR1 mutation., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Introduction: In the setting of pediatric and adolescent young adult cancer, increased access to genomic profiling has enhanced the detection of genetic variation associated with cancer predisposition, including germline syndromic conditions. Noonan syndrome (NS) is associated with the germline RAS pathway activating alterations and increased risk of cancer. Herein, we describe our comprehensive molecular profiling approach, the association of NS with glioma and glioneuronal tumors, and the clinical and histopathologic characteristics associated with the disease., Methods: Within an institutional pediatric cancer cohort (n = 314), molecular profiling comprised of paired somatic disease-germline comparator exome analysis, RNA sequencing, and tumor classification by DNA methylation analysis was performed., Results: Through the implementation of paired analysis, this study identified 4 of 314 (1.3%) individuals who harbored a germline PTPN11 variant associated with NS, of which 3 individuals were diagnosed with a glioma or glioneuronal tumor. Furthermore, we extend this study through collaboration with a peer institution to identify two additional individuals with NS and a glioma or glioneuronal tumor. Notably, in three of five (60%) individuals, paired genomic profiling led to a previously unrecognized diagnosis of Noonan syndrome despite an average age of cancer diagnosis of 16.8 years. The study of the disease-involved tissue identified signaling pathway dysregulation through somatic alteration of genes involved in cellular proliferation, survival, and differentiation., Discussion: Comparative pathologic findings are presented to enable an in-depth examination of disease characteristics. This comprehensive analysis highlights the association of gliomas and glioneuronal tumors with RASopathies and the potential therapeutic challenges and importantly demonstrates the utility of genomic profiling for the identification of germline cancer predisposition., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Shatara, Schieffer, Melas, Varga, Thomas, Bucknor, Costello, Wheeler, Kelly, Miller, Rodriguez, Mathew, Lee, Crotty, Leary, Paulson, Cole, Abdelbaki, Finlay, Lazow, Salloum, Fouladi, Boué, Mardis and Cottrell.)

Later eating rhythm (LER) refers to later timing, greater energy intake (EI), and higher frequency of eating occasions (meal/snack) in the evening. The significance of LER in child health is becoming increasingly recognised. However, the lack of consensus regarding definitions of LER make it challenging to fully comprehend its role. This data note describes LER variables derived in the Avon Longitudinal Study of Parents and Children (ALSPAC), an ongoing birth cohort which enrolled 14,541 pregnant women living in Avon, UK, with an expected date of delivery between April 1991 - December 1992. When children were 7 years, parents completed a structured 3-day food diary, recording all foods/drinks consumed over 3 days (preferably 1 weekend day and 2 weekdays). Data was available for 7,285 children (50.1% response rate). A subsample of 4,869 children had exact time of eating occasions added to the existing database, which only included broad indications of eating timing based on 2-7 hour long meal slots. 13 LER variables were derived for the entire week and weekdays/weekend days separately. These comprise: 1) eating around individual bedtime (number days); 2) eating around average bedtime (number days); 3) time of evening main meal (hrs:mins); 4) time of last eating occasion (hrs:mins); 5) EI in the evening (percentage of total daily energy intake, %TDEI); 6) EI within 2hrs before bedtime (%TDEI); 7) EI for evening main meal (%TDEI); 8) EI for evening snacks (%TDEI); 9) Night eating1 (NE1): eating over 30% of total daily energy intake after 18:00 (number days); 10) NE2: eating over 25% of total daily energy intake within 2hrs before bedtime (number days); 11) eating frequency after 17:00 (number of eating occasions); 12) regularity of dinner (number of days); 13) frequency of evening snacks (number days). We describe the derivation, prevalence and inter-corelations between LER variables., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Zou M et al.)

Introduction: Syphilis, a bacterial infection caused by Treponema pallidum, can affect a wide variety of organ systems of its host. We aim to present the cases of two patients who presented to an urban, tertiary care, academic Emergency Department with ocular symptoms who underwent imaging, laboratory, and specialist evaluation and were ultimately diagnosed with ocular syphilis., Case Report: The first patient is a 46-year-old female who presented to the Emergency Department with painless complete vision loss in a unilateral eye. Her exam was significant for bilateral papilledema, and further workup revealed a retinal detachment in the affected eye. Rapid plasma reagin (RPR) titers resulted positive with 1:128 and a reactive fluorescent treponemal antibody (FTA). Further workup including lumbar puncture and magnetic resonance imaging were unable to be obtained due to patient refusal and multiple discharges against medical advice. The second patient is a 38-year-old female with a history of intravenous drug use who presented for bilateral circumferential peripheral vision loss with central sparing. The examination showed bilateral papilledema. Lumbar puncture was performed with normal intracranial pressure. RPR titers resulted positive with 1:128. MRI and ophthalmology evaluation did not reveal any other etiology or explanation for papilledema., Conclusion: This case series highlights the importance of considering syphilis as a possible cause of ocular symptoms in high risk patient populations and the need for prompt and appropriate treatment given the increasing prevalence of syphilis worldwide., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Importance: The COVID-19 pandemic has led to 775 million documented cases and over 7 million deaths worldwide as of March 2024 and is an ongoing health crisis. To limit viral spread within households and in the community, public health officials have recommended self-isolation, self-quarantine of exposed household contacts, and mask use. Yet, risk of household transmission (HHT) may be underestimated due to low frequency of sampling, and risk factors for HHT are not well understood., Objectives: To estimate the secondary attack rate of SARS-CoV-2 within households and to define the risk factors for new infections in household members who are in close contact with the index case., Design, Setting, and Participants: In this prospective cohort study, from March 2020-December 2021 we enrolled 60 households with index cases who tested positive for SARS-CoV-2. All household contacts and index cases were tested daily for SARS-CoV-2 via reverse transcription polymerase chain reaction (RT-PCR) using self-collected anterior nares specimens. Households were followed until all study participants in the household tested negative for SARS-CoV-2 for seven consecutive days. We collected sex, age, race/ethnicity, comorbidities, and relationship to index case for secondary contacts, household level characteristics including primary income, household density, and square feet per person on property. We compared the sociodemographic variables between COVID-19 positive and negative household members and between households where secondary transmission did and did not occur., Main Outcomes and Measures: Daily anterior nares swabs were tested for SARS-CoV-2 using RT-PCR, in order to assess duration of nasal shedding of SARS-CoV-2, as well as risk of transmission to secondary household contacts., Results: Of the 163 participants in this study, 84 (51.5%) were women; median age (IQR) was 36.0 (17.0-54.0) years of age; 78 (47.8%) were white and 48 (29.5%) were Hispanic/LatinX. Of the fifty households with household contacts, at least one secondary case occurred in twenty-six households (52.0%) and forty-five household contacts (43.7%) were infected. Secondary attack rate was lowest among children of index cases (6/23, 26.1%). Modified Poisson regression identified that the risk of transmission to household contacts increases significantly with age (Risk ratio for each increase in years of age = 1.01, 95% CI = 1.00-1.02). Mixed effects regression models identified that participants with chronic diseases, such as asthma, diabetes, cancer, or cardiac disease, had higher Cts at baseline when compared to participants without chronic diseases (6.62, 95% CI: 1.46-11.77, p = 0.02) and show a slower rate of increase in Ct over time (-0.43, 95% CI: -0.77 to -0.09, p = 0.02)., Conclusions and Relevance: This study suggests that HHT represents a key source of community-based infection of SARS-CoV-2. Allocation of resources for contact investigations and prevention interventions should focus on the individuals at highest risk of infection in households, especially those with higher density homes., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Altamirano et al.

Objectives: Investigate associations between cleft laterality in patients with non-syndromic unilateral cleft lip and palate (UCLP) and oral-health, dental-arch, speech, audiological, psychological and nasolabial-aesthetic outcomes., Methods: Secondary data analysis of the outcomes of 5-year-old children with non-syndromic complete UCLP identified from three studies: Cleft Collective (n = 155), Cleft Care UK (CCUK) (n = 266) and Clinical Standards Advisory Group (CSAG) study (n = 238). Outcome measures included occlusal assessment using the 5-year-old's index score, speech intelligibility rating using the CAPS-A Audit tool, audiological assessment using pure tone audiometry, nasolabial aesthetic assessment using the Asher-McDade tool, oral-health assessment using decayed, missing, filled teeth scores and parent-reported outcomes. Logistic regression with adjustment for age, sex and index-of-multiple-deprivation scores were performed., Results: No differences were found in patient-reported outcomes between the left and right clefts in the Cleft Collective study. From the CCUK study, right clefts had poorer speech (n = 236; 95% CI 1.09, 3.42; and P = .03) and hearing outcomes (n = 211; 95% CI 1.03, 3.43; P = .04). In the CSAG study, patients with left clefts were more likely to be teased (n = 213; 95% CI 0.26, 0.85; and P = .01)., Conclusion: Weak associations between cleft laterality, speech, hearing and psychological outcomes were found, however the findings were inconsistent across the studies. This study contributes to evidence of associations between laterality and outcomes in children born with UCLP., (© 2024 The Authors.

Purpose: To determine whether tranexamic acid (TXA) is safe to administer preoperatively in patients undergoing hip arthroscopy by comparing the venous thromboembolic rate and complication rate between patients who did and did not receive TXA preoperatively., Methods: This was a multicenter consecutive-cohort series of patients who underwent arthroscopic hip surgery between 2014 and 2021. The 2 cohorts comprised patients who did and did not receive TXA preoperatively (single dose of 1-2 g), after a practice change. Data were collected via chart review. Surgical outcomes included days until follow-up, visual analog scale pain score at first follow-up, total operating room (OR) time, number of arthroscopic fluid bags (3 L/bag), and complications and revision operations up to 1 year after surgery. The Mann-Whitney U test was performed for continuous variables, and the χ 2 test, for categorical variables., Results: A total of 862 patients were identified: 449 (52%) received TXA and 413 (48%) did not. Patient demographic characteristics including age, sex, height, weight, body mass index, smoking status, and procedures performed, as well as number of anchors used (3.5 anchors for no TXA vs 3.7 anchors for TXA) and traction time (38 minutes for no TXA vs 40 minutes for TXA), did not significantly differ between groups. Significantly more patients underwent prior hip arthroscopy in the TXA group (n = 45; primary, n = 404) than in the group that did not receive TXA (n = 25; primary, n = 388) (P = .03). Visual analog scale pain scores at the first follow-up visit (2.61 for no TXA vs 2.62 for TXA, P = .62) and the need for subsequent revision surgery (24 patients with no TXA vs 18 patients with TXA, P = .68) were not significantly different. TXA use was associated with less arthroscopic fluid utilization (5.9 bags of 3 L of fluid for no TXA vs 5.3 bags of 3 L of fluid for TXA, P < .01) and less total OR time (99.5 minutes for no TXA vs 90.0 minutes for TXA, P < .01). There was a higher overall complication rate in the group that did not receive TXA (n = 27) than in the group that did (n = 10) (P = .01). However, if lateral femoral cutaneous nerve neurapraxia was excluded, then no difference in complication rate was observed (P = .24)., Conclusions: There was no difference in the incidence of venous thromboembolic complications between patients who did and did not receive TXA preoperatively. We observed a lower overall complication rate in patients who received TXA preoperatively; however, this normalized between the 2 groups when lateral femoral cutaneous nerve neuritis was excluded. No difference in early pain control or revision surgery rate was observed between groups. Although there was statistically less arthroscopic fluid utilization and less total OR time in the group that received TXA, further studies are needed to clarify whether this is clinically meaningful. Preoperatively administered TXA is a safe adjunct medication in patients undergoing arthroscopic hip surgery., Level of Evidence: Level III, retrospective multicenter consecutive series., Competing Interests: Disclosures The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: R.W. reports board membership and a consulting or advisory relationship with University of Iowa.

Time-limited eating is a dietary intervention whereby eating is limited to a specific window of time during the day. The usual eating windows of adults, and how these can be manipulated for dietary interventions, is well documented. However, there is a paucity of data on eating windows of young people, the manipulation of which may be a useful intervention for reducing obesity. This paper reviewed the existing literature on the eating windows of children and adolescents, aged 5-18 years, plus clock times of first and last intakes and variations by subgroup. Two databases (Medline and Embase) were searched for eligible papers published between February 2013 and February 2023, with forward searching of the citation network of included studies on Web of Science. Articles were screened, and data extracted, in duplicate by two independent reviewers. Ten studies were included, with both observational and experimental designs. Narrative synthesis showed large variations in eating windows with average values ranging from 9.7 h to 16.4 h. Meta-analysis, of five studies, showed a pooled mean daily eating window of 11.3 h (95% CI 11.0, 11.7). Large variations in eating windows exist across different study populations; however, the pooled data suggest that it may be possible to design time-limited eating interventions in paediatric populations aimed at reducing eating windows. Further high-quality research, investigating eating windows and subsequent associations with health outcomes, is needed.
